To the stockholders of International Seaways, Inc. and shareholders of Diamond S Shipping Inc.

TRANSACTION PROPOSED — YOUR VOTE IS VERY IMPORTANT

Dear investors:

On March 30, 2021, International Seaways, Inc., or INSW, Dispatch Transaction Sub, Inc., a wholly owned subsidiary of INSW, or Merger Sub, and Diamond S Shipping Inc., or Diamond S, entered into an Agreement and Plan of Merger, or the merger agreement, pursuant to which, subject to approval of INSW stockholders and Diamond S shareholders and the satisfaction or (to the extent permitted by law) waiver of other specified closing conditions, INSW and Diamond S will combine in an all-stock merger of equals, or the merger. At the completion of the merger, Merger Sub will merge with and into Diamond S, with Diamond S surviving the merger and becoming a wholly owned subsidiary of INSW. Each of the common stock of INSW and the common stock of Diamond S is traded on the New York Stock Exchange, or the NYSE, under the symbols “INSW” and “DSSI,” respectively. The common stock of the combined company will be listed on the NYSE under the symbol “INSW.”

If the merger is completed, each share of Diamond S common stock (other than shares held by Diamond S, INSW, Merger Sub or any of their respective direct or indirect wholly owned subsidiaries) will be converted into the right to receive 0.55375 validly issued, fully paid and non-assessable shares of common stock of INSW (and, if applicable, cash in lieu of fractional shares), or the merger consideration, less any applicable withholding taxes. Based on the current number of shares of Diamond S common stock outstanding, INSW expects to issue approximately 22,683,532 shares of INSW common stock to holders of Diamond S common stock in the aggregate in the merger. Based on the current number of shares of INSW common stock and Diamond S common stock outstanding and reserved for issuance, we estimate that, immediately following the consummation of the merger, pre-merger INSW stockholders will own approximately 55.75% and former Diamond S shareholders will own approximately 44.25% of the common stock of the combined company. Prior to the consummation of the merger, INSW is permitted to pay a special dividend to INSW stockholders in an aggregate amount equal to $31.5 million, which special dividend will not result in a change to the base exchange ratio. The base exchange ratio is subject to an upward adjustment to the extent that INSW sells any interest in, or assets of, its TI Asia Limited or TI Africa Limited joint ventures prior to the consummation of the merger and pays a special dividend to INSW’s stockholders from the proceeds of any such sale (up to a maximum of $25 million). For more details on the merger consideration, see “The Merger Agreement — Merger Consideration.”

Each of INSW and Diamond S is holding a special meeting of its respective stockholders or shareholders, as applicable, to vote on the proposals necessary to complete the merger. Information about each meeting, the merger and the other business to be considered by stockholders of INSW and shareholders of Diamond S at the respective special meetings is contained in this joint proxy statement/prospectus. Any stockholder of INSW or shareholder of Diamond S entitled to attend and vote at the applicable special meeting is entitled to appoint a proxy to attend and vote on such stockholder’s or shareholder’s behalf. Such proxy need not be a holder of INSW common stock or Diamond S common stock. We urge you to read this joint proxy statement/prospectus and the annexes and documents incorporated by reference carefully. You should also carefully consider the risks that are described in the “Risk Factors.”

Your vote is very important regardless of the number of shares of INSW common stock or Diamond S common stock that you own. The merger cannot be completed without (1) the adoption of the merger agreement by the affirmative vote of holders of at least a majority of the outstanding shares of Diamond S common stock entitled to vote on the authorization of the merger agreement at the Diamond S special meeting and (2) the approval of the issuance of INSW common stock to Diamond S shareholders in connection with the merger by the affirmative vote of the holders of a majority of the outstanding shares of INSW common stock present and entitled to vote at the INSW special meeting.

Whether or not you plan to attend the INSW special meeting or the Diamond S special meeting, please submit your proxy as soon as possible to make sure that your shares are represented at the applicable meeting.

We look forward to the successful combination of INSW and Diamond S.

Sincerely,

Lois K. Zabrocky
President and
Chief Executive Officer
International Seaways, Inc.

Chief Executive Officer
Diamond S Shipping Inc.

Neither the Securities and Exchange Commission nor any state securities commission has approved or disapproved of the merger or the other transactions described in this joint proxy statement/prospectus or the securities to be issued in connection with the merger or determined if this joint proxy statement/prospectus is accurate or complete. Any representation to the contrary is a criminal offense.

The accompanying joint proxy statement/prospectus is dated June 11, 2021 and is first being mailed to stockholders of INSW and shareholders of Diamond S on or about June 11, 2021.

To vote on a proposal (the “INSW share issuance proposal”) to approve the issuance (the “INSW share issuance”) of INSW common stock, no par value (“INSW common stock”), as consideration to Diamond S Shipping Inc. (“Diamond S”) shareholders in connection with the merger contemplated by the Agreement and Plan of Merger, dated as of March 30, 2021, by and among INSW, Dispatch Transaction Sub, Inc., a wholly owned subsidiary of INSW (“Merger Sub”) and Diamond S; and

Adjournment of the INSW Special Meeting. To vote on a proposal (the “INSW adjournment proposal”) to approve the adjournment of the INSW special meeting to a later date or dates, if necessary or appropriate, to solicit additional proxies in the event there are not sufficient votes at the time of the INSW special meeting to approve the INSW share issuance proposal.

INSW will transact no other business at the INSW special meeting, except such business as may properly be brought before the INSW special meeting or any adjournment or postponement thereof. Please refer to the joint proxy statement/prospectus of which this notice is a part for further information with respect to the business to be transacted at the INSW special meeting.

A special committee of the INSW board of directors (the “INSW Board”) has fixed the close of business on June 11, 2021 as the record date for the INSW special meeting (the “INSW record date”). Only INSW stockholders of record at that time are entitled to receive notice of, and to vote at, the INSW special meeting or any adjournment or postponement thereof. INSW is commencing its solicitation of proxies on or about June 11, 2021. INSW will continue to solicit proxies until the date of the INSW special meeting.

Completion of the merger is conditioned upon, among other things, approval of the INSW share issuance proposal by the INSW stockholders, which requires the affirmative vote of the holders of a majority of the outstanding shares of INSW common stock present and entitled to vote at the INSW special meeting.

The INSW Board unanimously approved and declared advisable the merger agreement and the transactions contemplated by the merger agreement, including the merger, and determined that the merger agreement and the transactions contemplated by the merger agreement, including the merger and the INSW share issuance are advisable and fair to and in the best interests of INSW and its stockholders, and unanimously recommends that INSW stockholders vote:

•

“FOR” the INSW share issuance proposal; and

•

“FOR” the INSW adjournment proposal.

TABLE OF CONTENTS

Your vote and that your shares be represented at the meeting are both very important, regardless of the number of shares of INSW common stock that you own. The votes cast in favor of the INSW share issuance proposal must exceed the aggregate of votes cast against the INSW share issuance proposal and abstentions. Whether or not you expect to attend the INSW special meeting virtually, to ensure your representation at the INSW special meeting, we urge you to submit a proxy to vote your shares of INSW common stock as promptly as possible by (1) visiting the Internet site listed on the INSW proxy card, (2) calling the toll-free number listed on the INSW proxy card or (3) submitting your INSW proxy card by mail by using the provided self-addressed, stamped envelope. Submitting a proxy will not prevent you from voting in person (by participating through the virtual meeting website), but it will help to secure a quorum and avoid added solicitation costs. Any eligible holder of INSW common stock who is present at the INSW special meeting may vote in person (by participating through the virtual meeting website ), thereby revoking any previous proxy. In addition, a proxy may also be revoked in writing before the INSW special meeting in the manner described in the accompanying joint proxy statement/prospectus. If your shares of INSW common stock are held in the name of a bank, broker or other nominee, please follow the instructions on the voting instruction card furnished by the bank, broker or other nominee.

QUESTIONS AND ANSWERS ABOUT THE BUSINESS COMBINATION

The following questions and answers briefly address some commonly asked questions about the merger, the merger agreement, the transactions contemplated by the merger agreement, the INSW special meeting and the Diamond S special meeting. They may not include all the information that is important to INSW stockholders and Diamond S shareholders. INSW stockholders and Diamond S shareholders should carefully read this entire joint proxy statement/prospectus, including the annexes and the other documents referred to or incorporated by reference herein.

Q: What is the merger?

A: INSW, Merger Sub and Diamond S have entered into a merger agreement. A copy of the merger agreement is attached as Annex A to this joint proxy statement/prospectus. The merger agreement contains the terms and conditions of the proposed stock-for-stock merger between INSW and Diamond S, whereby INSW and Diamond S will combine in an all-stock merger of equals. Under the merger agreement, subject to satisfaction or (to the extent permitted by law) waiver of the conditions set forth in the merger agreement and described hereafter, in each case prior to the completion of the merger, Merger Sub will merge with and into Diamond S, with Diamond S continuing as the surviving corporation and a wholly owned subsidiary of INSW. As a result of the merger, Diamond S will no longer be a publicly-held company. Following the merger, Diamond S common stock (which is currently listed on the NYSE under the symbol “DSSI”) will be delisted from the NYSE, and deregistered under the Exchange Act. Following the completion of the merger, the name of the combined company will be International Seaways, Inc. and the common stock of the combined company will be listed on the NYSE under the symbol “INSW.”

Q: Why am I receiving these materials?

A: You are receiving this joint proxy statement/prospectus to help you decide how to vote your shares of INSW common stock or Diamond S common stock with respect to the INSW share issuance proposal or the Diamond S merger proposal, as the case may be, and the other matters to be considered at the special meetings.

The merger cannot be completed unless, among other things, (1) INSW stockholders approve the issuance of INSW common stock to Diamond S shareholders in connection with the INSW special meeting and (2) Diamond S shareholders adopt the merger agreement at the Diamond S special meeting.

This joint proxy statement/prospectus constitutes both a joint proxy statement of INSW and Diamond S and a prospectus of INSW. It is a joint proxy statement because each of the INSW Board and the Diamond S Board is soliciting proxies from its respective stockholders or shareholders, as applicable. It is a prospectus because INSW will issue shares of INSW common stock in exchange for outstanding shares of Diamond S common stock in the merger. Information about the INSW special meeting, the Diamond S special meeting, the merger, the merger agreement and the other business to be considered by INSW stockholders at the INSW special meeting and the Diamond S shareholders at the Diamond S special meeting is contained in this joint proxy statement/prospectus. INSW stockholders and Diamond S shareholders should read this information carefully and in its entirety. The enclosed voting materials allow INSW stockholders and Diamond S shareholders to vote their shares by proxy without attending the applicable special meeting virtually.

Q: What will Diamond S shareholders receive in the merger?

A: If the merger is completed, each share of Diamond S common stock (other than excluded shares) will be converted into the merger consideration, which is the right to receive 0.55375 fully paid and non-assessable shares of INSW common stock, and, if applicable, cash in lieu of fractional shares. The base exchange ratio is subject to an upward adjustment to the extent INSW sells any interest in the FSO Joint Ventures or any of the assets of the FSO Joint Ventures prior to the effective time and declares and pays a special dividend to INSW stockholders with a record date for such dividend occurring prior to the effective time from the proceeds of any such sale (up to a maximum of $25 million). The merger consideration is described in more detail in “The Merger Agreement — Merger Consideration.”

TABLE OF CONTENTS

Q: What will INSW stockholders receive in the merger?

A: INSW stockholders will not receive any merger consideration, and their shares of INSW common stock will remain outstanding and will constitute shares of the combined company. Following the merger, shares of INSW common stock will continue to be traded on the NYSE under the symbol “INSW.”

Q: Will I still be paid dividends prior to the completion of the merger?

A: Yes. During the pendency of the merger, without the consent of Diamond S, INSW may declare and pay a regular quarterly cash dividend in an amount per share of up to $0.06 per quarter, the INSW special dividend and the INSW FSO dividend. It is expected that INSW will declare and pay the INSW special dividend prior to the closing of the merger, with a record date on or after the date of the INSW special meeting.

Diamond S has not paid any cash dividends since its inception. The terms of the merger agreement limit the ability of Diamond S to declare or pay dividends prior to the completion of the merger without INSW’s consent. In addition, certain of Diamond S’ debt instruments place restrictions on its ability to pay cash dividends.

Q: What respective equity stakes will INSW stockholders and Diamond S shareholders hold in the combined company immediately following the merger?

A: As of the date of this joint proxy statement/prospectus, based on the current number of shares of INSW common stock and Diamond S common stock outstanding and reserved for issuance and assuming the INSW FSO dividend is not paid, we estimate that, immediately following completion of the merger, pre-merger holders of INSW common stock will own approximately 55.75% and former holders of Diamond S common stock will own approximately 44.25% of the common stock of the combined company. The equity stake of INSW stockholders and Diamond S shareholders in the combined company immediately following the merger will depend on the number of shares of INSW common stock and Diamond S common stock issued and outstanding immediately prior to the merger and whether an exchange ratio adjustment event has occurred prior to the effective time of the merger.

Q: Will the market value of the merger consideration change between the date of this joint proxy statement/prospectus and the time the merger is completed?

A: Yes. Although the number of shares of INSW common stock that holders of Diamond S common stock will receive is fixed, the market value of the merger consideration will fluctuate between the date of this joint proxy statement/prospectus and the completion of the merger based upon the trading price of shares of INSW common stock. Any fluctuation in the trading price of shares of INSW common stock after the date of this joint proxy statement/prospectus will change the market value of the shares of INSW common stock that holders of Diamond S common stock will receive.

Q: When do INSW and Diamond S expect to complete the transaction?

A: INSW and Diamond S are working to complete the transaction as soon as practicable. We currently expect that the merger will be completed in the third quarter of 2021 after the Diamond S special meeting and the INSW special meeting (assuming the Diamond S shareholder approval and the INSW stockholder approval are obtained at the respective special meetings). Neither Diamond S nor INSW can predict, however, the actual date on which the merger will be completed because it is subject to conditions beyond each company’s control, including obtaining necessary regulatory approvals.

Q: What are INSW stockholders being asked to vote on?

A: INSW stockholders are being asked to vote on the following proposals:

Approval of the INSW Share Issuance. To vote on a proposal to authorize and approve the issuance of INSW common stock, no par value, to Diamond S shareholders in connection with the merger agreement, referred to as the INSW share issuance proposal; and

Adjournment of the INSW Special Meeting. To vote on a proposal to approve the adjournment of the INSW special meeting to a later date or dates, if necessary or appropriate, to solicit additional

TABLE OF CONTENTS

proxies in the event there are not sufficient votes at the time of the INSW special meeting to approve the INSW share issuance proposal, referred to as the INSW adjournment proposal.

Approval of the INSW share issuance proposal by INSW stockholders is required for completion of the merger.

Q: What are Diamond S shareholders being asked to vote on?

A: Diamond S shareholders are being asked to vote on the following proposals:

Adoption of the Merger Agreement. To vote on a proposal to adopt the merger agreement, which is further described in the section entitled “The Merger Agreement”, and a copy of which merger agreement is attached as Annex A to this joint proxy statement/prospectus, referred to as the Diamond S merger agreement proposal;

Approval of the Diamond S merger proposal by Diamond S shareholders is required for completion of the merger.

Q: What vote is required to approve each proposal at the INSW special meeting?

A: The INSW Share Issuance Proposal: The affirmative vote of the holders of a majority of the outstanding shares of INSW common stock present and entitled to vote (in person or by proxy) at the INSW special meeting is required to approve the INSW share issuance proposal.

The INSW Adjournment Proposal: The affirmative vote of the holders of a majority of the outstanding shares of INSW common stock present and entitled to vote (in person or by proxy) at the INSW special meeting is required to approve the INSW adjournment proposal.

Q: What vote is required to approve each of the proposals at the Diamond S special meeting?

A: The Diamond S Merger Proposal: The affirmative vote of the holders of at least a majority of the outstanding shares of Diamond S common stock entitled to vote (in person or by proxy) at the Diamond S special meeting is required to authorize and approve the Diamond S merger proposal.

The Diamond S Merger-Related Compensation Proposal: The affirmative vote of the votes cast by holders outstanding shares of Diamond S common stock entitled to vote (in person or by proxy) at the Diamond S special meeting is required to approve the Diamond S merger-related compensation proposal.

The Diamond S Adjournment Proposal: The affirmative vote of a majority of the votes cast by holders of outstanding shares of Diamond S common stock entitled to vote (in person or by proxy) at the Diamond S special meeting is required to approve the Diamond S adjournment proposal.

Q: Why am I being asked to consider and vote on the Diamond S merger-related compensation proposal?

A: Under SEC rules, Diamond S is required to seek a non-binding, advisory vote with respect to the compensation that may be paid or become payable to Diamond S’ named executive officers that is based on or otherwise relates to the merger, or “golden parachute” compensation.

TABLE OF CONTENTS

Q: What happens if Diamond S shareholders do not approve, by non-binding, advisory vote, the Diamond S merger-related compensation proposal?

A: The vote on the Diamond S merger-related compensation proposal is separate and apart from the votes to approve the other proposals being presented at the Diamond S special meeting. Because the vote on the Diamond S merger-related compensation proposal is advisory in nature only, it will not be binding on Diamond S, INSW or the combined company in the merger. Accordingly, the merger-related compensation will be paid to Diamond S’ named executive officers to the extent payable in accordance with the terms of their compensation agreements and arrangements even if Diamond S shareholders do not approve the Diamond S merger-related compensation proposal.

Q: Do any of INSW’s or Diamond S’ directors or executive officers have interests in the merger that may differ from those of INSW stockholders or Diamond S shareholders?

A: Certain of INSW’s non-employee directors and executive officers and Diamond S’ non-employee directors and executive officers have certain interests in the merger that may be different from, or in addition to, the interests of INSW stockholders and Diamond S shareholders generally. The INSW Board was aware of the interests of INSW’s directors and executive officers, the Diamond S Board was aware of the interests of Diamond S’ directors and executive officers, and each board considered such interests when it approved the merger agreement and the transactions contemplated thereby and in making its recommendations to its respective stockholders or shareholders, as applicable. For more information regarding these interests, see sections entitled “The Merger — Interests of Certain of INSW’s Directors and Executive Officers in the Merger” and “The Merger — Interests of Diamond S’ Directors and Executive Officers in the Merger.”

Q: How many votes do I have?

A: Each INSW stockholder is entitled to one vote for each share of INSW common stock held of record as of the INSW record date and each Diamond S shareholder is entitled to one vote for each share of Diamond S common stock held of record as of the Diamond S record date.

As of the close of business on June 1, 2021, there were 28,087,011 shares of INSW common stock outstanding. As of the close of business on June 1, 2021, there were 40,612,811 shares of Diamond S common stock outstanding. As summarized below, there are some important distinctions between shares held of record and those owned beneficially in street name.

Q: Are there any INSW stockholders who have already committed to voting in favor of any of the proposals at the INSW special meeting?

A: Contemporaneously with the execution of the merger agreement, Diamond S entered into a voting and support agreement (a copy of which is attached as Annex D to this joint proxy statement/prospectus) with certain INSW stockholders affiliated with Cyrus Capital Partners, L.P. (collectively, the “Cyrus stockholders”), pursuant to which the Cyrus stockholders agreed, among other things, subject to the terms and conditions thereof, to vote all of the shares of INSW common stock held by the Cyrus stockholders as of such date in favor of the INSW share issuance proposal at the INSW special meeting. The Cyrus stockholders beneficially owned approximately 14.3% of the outstanding shares of INSW common stock as of June 1, 2021. For more information, please see “The Merger Agreement — Cyrus Support Agreement.”

Q: Are there any Diamond S shareholders who have already committed to voting in favor of the proposals at the Diamond S special meeting?

(“CMTC”) (collectively, the “Capital shareholders”) (a copy of which is attached as Annex F to this joint proxy statement/prospectus), pursuant to which the WL Ross shareholders and the Capital shareholders have each agreed, among other things, subject to the terms and conditions thereof, to vote all of the shares of Diamond S common stock held by the WL Ross shareholders and the Capital shareholders as of such date

TABLE OF CONTENTS

If your shares are held in “street name,” through a bank, broker or other nominee, that institution will send you separate instructions describing the procedures for voting your shares.

Q: What is the difference between holding shares as a record holder and as a beneficial owner?

A: You are a “record holder” if your shares are registered directly in your name with INSW’s transfer agent, Computershare Trust Company, N.A., referred to as Computershare, or Diamond S’ transfer agent, which is also Computershare. As the record holder, you have the right to vote virtually at the INSW special meeting or the Diamond S special meeting, as applicable. You may also vote by Internet, telephone or mail, as described in the notice and above under the heading “How do I vote?”. You are deemed to beneficially own shares in “street name” if your shares are held by a bank, broker or other nominee. Your bank, broker or other nominee will send you, as the beneficial owner, a package describing the procedure for voting your shares. You should follow the instructions provided by them to vote your shares. If you beneficially own your shares, you are invited to attend the INSW special meeting or Diamond S special meeting, as applicable, virtually; however, you may not vote your shares in person at the INSW special meeting or the Diamond S special meeting, as applicable, unless you obtain a “legal proxy” from your bank, broker or other nominee that holds your shares, giving you the right to vote the shares at the INSW special meeting or the Diamond S special meeting, as applicable.

Q: If my shares are held in “street name” by a bank, broker or other nominee, will my bank, broker or other nominee vote my shares for me?

A: If your shares are held in “street name” by a bank, broker or other nominee, you must provide the record holder of your shares with instructions on how to vote your shares. Please follow the voting instructions provided by your bank, broker or other nominee. Please note that you may not vote shares held in street name by returning a proxy card directly to INSW or Diamond S, as applicable, or by voting virtually at the INSW special meeting or Diamond S special meeting, as applicable, unless you provide a “legal proxy,” which you must obtain from your bank, broker or other nominee. Your bank, broker or other nominee is obligated to provide you with a voting instruction card for you to use.

Banks, brokers or other nominees who hold shares in street name for a beneficial owner of those shares typically have the authority to vote in their discretion on “routine” proposals when they have not received instructions from beneficial owners. However, banks, brokers or other nominees are not allowed to exercise their voting discretion with respect to the approval of matters determined to be “non-routine” without specific instructions from the beneficial owner. It is expected that all proposals to be voted on at each of the INSW special meeting and the Diamond S special meeting are “non-routine” matters. Broker non-votes occur when a broker or nominee is not instructed by the beneficial owner of shares to vote on a particular proposal for which the bank, broker or other nominee does not have discretionary voting power.

If you are a beneficial owner of INSW common stock and you do not instruct your bank, broker or other nominee on how to vote your shares:

•

your bank, broker or other nominee may not vote your shares on the INSW share issuance proposal, which broker non-votes, if any, will have no effect on the outcome of such proposal; and

•

your bank, broker or other nominee may not vote your shares on the INSW adjournment proposal, which broker non-votes, if any, will have no effect on the outcome of such proposal.

If you are a beneficial owner of Diamond S common stock and you do not instruct your bank, broker or other nominee on how to vote our shares:

•

your bank, broker or other nominee may not vote your shares on the Diamond S merger proposal, which broker non-votes, if any, will have the same effect as a vote “AGAINST” such proposal;

•

your bank, broker or other nominee may not vote your shares on the Diamond S merger-related compensation proposal, which broker non-votes, if any, will have no effect on the outcome of such proposal; and

•

your bank, broker or other nominee may not vote your shares on the Diamond S adjournment proposal, which broker non-votes, if any, will have no effect on the outcome of such proposal.

Q: What if I fail to vote or abstain?

A: For purposes of the INSW special meeting, an abstention occurs when a INSW stockholder attends the INSW special meeting virtually and does not vote or returns a proxy with an “abstain” instruction.

INSW Share Issuance Proposal: An abstention will have the same effect as a vote cast “AGAINST” the INSW share issuance proposal. If a INSW stockholder is not present virtually at the INSW special meeting and does not respond by proxy, it will have no effect on the vote count for such proposal.

INSW Adjournment Proposal: An abstention will have the same effect as a vote cast “AGAINST” the INSW adjournment proposal. If a INSW stockholder is not present virtually at the INSW special meeting and does not respond by proxy, it will have no effect on the vote count for such proposal.

For purposes of the Diamond S special meeting, an abstention occurs when a Diamond S shareholder attends the Diamond S special meeting virtually and does not vote or returns a proxy with an “abstain” instruction.

Diamond S Merger Proposal: An abstention will have the same effect as a vote cast “AGAINST” the Diamond S merger proposal. If a Diamond S shareholder is not present virtually at the Diamond S special meeting and does not respond by proxy, it will have the effect of a vote cast “AGAINST” such proposal.

Diamond S Merger-Related Compensation Proposal: An abstention will have the same effect as a vote cast “AGAINST” the Diamond S merger-related compensation proposal. If a Diamond S shareholder is not present virtually at the Diamond S special meeting and does not respond by proxy, it will have no effect on the vote count for such proposal.

Diamond S Adjournment Proposal: An abstention will have the same effect as a vote cast “AGAINST” the Diamond S adjournment proposal. If a Diamond S shareholder is not present virtually at the Diamond S special meeting and does not respond by proxy, it will have no effect on the vote count for such proposal.

Q: What will happen if I return my proxy or voting instruction card without indicating how to vote?

A: If you sign and return your proxy or voting instruction card without indicating how to vote on any particular proposal, the common stock represented by your proxy will be voted as recommended by the INSW Board or the Diamond S Board, as applicable, with respect to that proposal.

Q: May I change or revoke my vote after I have delivered my proxy or voting instruction card?

A: Yes. If you are a record holder, you may change or revoke your vote before your proxy card is voted at the INSW special meeting or Diamond S special meeting, as applicable, as described herein. You may do so in one of the following four ways:

•

by logging onto the Internet website specified on your proxy card in the same manner you would to submit your proxy electronically or by calling the telephone number specified on your proxy card, in each case, if you are eligible to do so;

•

by sending a notice of revocation to the corporate secretary of INSW or Diamond S, as applicable;

•

by sending a completed proxy card bearing a later date than your original proxy card; or

•

by attending the INSW Special Meeting or the Diamond S Special Meeting virtually, as applicable, and voting.

If you choose any of the first three methods, you must take the described action no later than the beginning of the INSW special meeting or the Diamond S special meeting, as applicable.

If your shares are held in an account at a bank, broker or other nominee and you have delivered your voting instruction card or otherwise given instruction on how to vote your shares to your bank, broker or other nominee, you should contact your bank, broker or other nominee to change your vote.

TABLE OF CONTENTS

Q: What are the material U.S. federal income tax consequences of the merger to holders of Diamond S common stock?

A: It is intended that, for U.S. federal income tax purposes, (i) the merger qualify as a “reorganization” under Section 368(a) of the Code, to which each of INSW, Merger Sub, and Diamond S are parties under Section 368(b) of the Code, and (ii) the merger not result in the recognition of gain under Section 367(a)(1) of the Code (other than, in certain circumstances, a transfer by a holder of Diamond S common stock that is a United States person (as defined in Section 7701 of the Code) and that holds 5% or more by vote or by value (within the meaning of Treasury Regulations Section 1.367(a)¬-3(b)(1)(i)) of the INSW common stock outstanding immediately following the merger) (the “Intended Tax Treatment”). If the merger so qualifies, U.S. Holders (as defined below in the section entitled “Material U.S. Federal Income Tax Consequences of the Merger”) of Diamond S common stock generally should not recognize any gain or loss for U.S. federal income tax purposes upon the exchange of Diamond S common stock for INSW common stock. Although the parties will use commercially reasonable efforts to make such modifications or amendments to the structure as would permit the Intended Tax Treatment to be attained, the completion of the merger is not conditioned upon the receipt of an opinion of counsel to the effect that the merger qualifies for the Intended Tax Treatment. In addition, neither Diamond S nor INSW intends to request a ruling from the IRS regarding the U.S. federal income tax consequences of the merger. Accordingly, no assurance can be given that the IRS will not challenge the Intended Tax Treatment or that a court would not sustain such a challenge. You should read the section entitled “Material U.S. Federal Income Tax Consequences of the Merger” and consult your own tax advisors regarding the U.S. federal income tax consequences of the merger to you in your particular circumstances, as well as tax consequences arising under the laws of any state, local or non-U.S. taxing jurisdiction.

Q: Where can I find the voting results of the INSW special meeting and the Diamond S special meeting?

A: The preliminary voting results will be announced at each of the INSW special meeting and the Diamond S special meeting. In addition, within four business days following certification of the final voting results, each of INSW and Diamond S intends to file the final voting results with the SEC on a Current Report on Form 8-K.

Q: Are holders of INSW common stock or Diamond S common stock entitled to dissenters or appraisal rights?

A: No. Holders of INSW common stock and holders of Diamond S common stock are not entitled to appraisal rights under the BCA. For more information, see the section entitled “The Merger — No Dissenters or Appraisal Rights.”

Q: What happens if I sell my shares of INSW common stock after the INSW record date but before the INSW special meeting?

A: The INSW record date for the INSW special meeting is earlier than the date of the INSW special meeting and earlier than the date that the merger is expected to be completed. If you sell or otherwise transfer your shares of INSW common stock after the INSW record date but before the date of the INSW special meeting, you will retain your right to vote at the INSW special meeting.

Q: What happens if I sell my shares of Diamond S common stock after the Diamond S record date but before the Diamond S special meeting?

A: The Diamond S record date for the Diamond S special meeting is earlier than the date of the Diamond S special meeting and earlier than the date that the merger is expected to be completed. If you sell or otherwise transfer your shares of Diamond S common stock after the Diamond S record date but before the date of the Diamond S special meeting, you will retain your right to vote at the Diamond S special meeting. However, you will not have the right to receive the merger consideration to be received by Diamond S shareholders in the merger. In order to receive the merger consideration, you must hold your shares through the completion of the merger.

The terms and conditions of the merger are contained in the merger agreement, a copy of which is attached as Annex A to this joint proxy statement/prospectus. You are encouraged to read the merger agreement carefully and in its entirety, as it is the primary legal document that governs the merger.

TABLE OF CONTENTS

the merger as a wholly owned subsidiary of INSW. Following the merger, Diamond S common stock will be delisted from the NYSE, will be deregistered under the Exchange Act and will cease to be publicly traded.

Merger Consideration (See page 96)

Subject to the terms and conditions set forth in the merger agreement, at the effective time, Diamond S shareholders will have the right to receive, with respect to each share of Diamond S common stock they hold at the effective time, 0.55375 validly issued, fully paid and non-assessable shares of INSW common stock, with cash paid in lieu of fractional shares of INSW common stock. The base exchange ratio will result in INSW stockholders owning approximately 55.75% of the outstanding shares of INSW common stock following the effective time and the pre-effective time Diamond S shareholders owning approximately 44.25% of the outstanding shares of INSW common stock following the effective time.

Unless INSW sells any interest in the FSO Joint Ventures prior to the closing of the merger and pays a special dividend to INSW stockholders from the proceeds of any such sale, the base exchange ratio is not subject to adjustment. The merger agreement does not contain any provision that would adjust the applicable exchange ratios based on fluctuations in the market value of either company’s common stock.

Fractional shares will not be issued in accordance with the merger. Any Diamond S shareholders that would have received a fractional share of INSW’s common stock based on the exchange ratio will instead receive an amount in cash equal to the product of such fractional part of a share of INSW’s common stock, multiplied by the volume-weighted average trading price of INSW common stock for the ten trading days preceding the date of the closing. It is expected that Cede & Co., as nominee for the Depository Trust Company, will be treated as a single holder for purposes of receiving cash in lieu of fractional shares.

Recommendation of the INSW Board and its Reasons for the Transaction (See page 57)

After careful consideration of various factors described in “The Merger — Recommendation of the INSW Board and its Reasons for the Transaction,” the INSW Board unanimously (1) declared that the merger agreement and consummation of the transactions contemplated thereby, including the merger, are advisable and fair to, and in the best interests of INSW and its stockholders, (2) approved the merger agreement and the transactions contemplated thereby, including the merger, (3) authorized the execution, delivery and performance of the merger agreement, (4) declared that the INSW share issuance proposal be submitted for consideration at the INSW special meeting, (5) recommended in favor of the INSW share issuance and (6) approved the inclusion of the recommendation in this joint proxy statement/ prospectus.

Accordingly, the INSW Board recommends that INSW stockholders vote:

•

“FOR” the INSW share issuance proposal; and

•

“FOR” the INSW adjournment proposal.

Opinion of INSW’s Financial Advisor (See page 61)

TABLE OF CONTENTS

financial point of view, of the base exchange ratio provided for in the merger pursuant to the merger agreement. At a meeting of the INSW Board held on March 30, 2021 to evaluate the merger, Jefferies rendered an oral opinion, confirmed by delivery of a written opinion dated March 30, 2021, to the INSW Board to the effect that, as of that date and based on and subject to various assumptions made, procedures followed, matters considered and limitations and qualifications on the review undertaken as described in its opinion, the base exchange ratio provided for in the merger pursuant to the merger agreement was fair, from a financial point of view, to INSW.

The full text of Jefferies’ opinion, which describes various assumptions made, procedures followed, matters considered and limitations and qualifications on the review undertaken by Jefferies, is attached as Annex B to this joint proxy statement/prospectus and is incorporated herein by reference. Jefferies’ opinion was provided for the use and benefit of the INSW Board (in its capacity as such) in its consideration of the merger and did not address the relative merits of the transactions contemplated by the merger agreement as compared to any alternative transaction or opportunity that might be available to INSW, nor did it address the underlying business decision by INSW to engage in the merger or the terms of the merger agreement (other than the base exchange ratio to the extent expressly specified therein) or the documents referred to therein. The base exchange ratio is subject to adjustment pursuant to the merger agreement, as to which adjustment Jefferies expressed no opinion. Jefferies’ opinion did not constitute a recommendation as to how any holder of shares of INSW common stock should vote on the merger or any matter related thereto. See “The Merger — Opinion of INSW’s Financial Advisor.”

Interests of Certain INSW’s Directors and Executive Officers in the Merger (See page 87)

In considering the recommendations of the INSW Board that INSW stockholders vote “FOR” the INSW share issuance proposal, INSW stockholders should be aware that certain directors and executive officers of INSW have agreements or arrangements that provide them with interests in the merger that may be different from, or in addition to, the interests of the other stockholders of INSW. The INSW Board was aware of these interests when it approved the merger agreement and the transactions contemplated thereby and recommended that INSW’s stockholders vote “FOR” the INSW share issuance proposal. Such interests include the continued service of certain directors or executive officers of INSW as directors or executive officers of the combined company and are more fully summarized below.

Proxies and Revocations

Any Diamond S shareholder of record entitled to vote at the Diamond S special meeting may submit a proxy by telephone, over the Internet, by returning the enclosed Diamond S proxy card in the accompanying prepaid reply envelope or may vote in person by virtually attending the Diamond S special meeting. If your shares of Diamond S common stock are held in “street name” through a bank, broker or other nominee, you should instruct your bank, broker or other nominee on how to vote your shares of Diamond S common stock using the instructions provided by your bank, broker or other nominee.

Most Diamond S shareholders have a choice of voting over the Internet, by using a toll-free telephone number, or by returning a completed proxy card or voting instruction form. Please check your notice, proxy card or the information forwarded by your broker, bank, trust or other holder of record to understand which options are available to you. The Internet and telephone voting procedures have been designed to authenticate Diamond S shareholders, to allow you to vote your shares, and to confirm that your instructions have been properly recorded. The Internet and telephone voting facilities for Diamond S shareholders of record will close at 11:59 p.m. on July 12, 2021. If your shares are held through a broker, bank, trust or other holder of record and Internet or telephone facilities are made available to you, these facilities may close sooner than those for shareholders of record.

You can revoke your proxy at any time before it is exercised by delivering a properly executed, later-dated proxy (including an Internet or telephone vote) or by voting virtually at the Diamond S special meeting. Executing your proxy in advance will not limit your right to vote at the Diamond S special meeting if you decide to attend in person (via the virtual meeting website) by going to www.virtualshareholdermeeting.com/DSSI2021SM and using your 16-digit control number included on your proxy card, voting instruction form or notice you received. However, if your shares are held in the name of a broker, bank, trust or other holder of record, you cannot vote at the Diamond S special meeting unless you have a legal proxy, executed in your favor, from the holder of record.

All shares entitled to vote and represented by properly executed proxies received prior to the Diamond S special meeting and not revoked will be voted at the Diamond S special meeting in accordance with your

TABLE OF CONTENTS

instructions. If you sign and return your proxy but do not indicate how your shares should be voted on a proposal, the shares represented by your proxy will be voted as the Diamond S Board recommends for such proposal.

If you are a record holder, you may change or revoke your vote before your proxy is voted at the Diamond S special meeting as described herein. You may do this in one of the following four ways: (1) by logging onto the Internet website specified on your Diamond S proxy card in the same manner you would to submit your proxy electronically or by calling the telephone number specified on your Diamond S proxy card, in each case, if you are eligible to do so; (2) by sending a notice of revocation to the Corporate Secretary of Diamond S; (3) by sending a completed Diamond S proxy card bearing a later date than your original Diamond S proxy card; or (4) by virtually attending the Diamond S special meeting in person and voting through the virtual meeting website during the Diamond S special meeting. Shareholders of record may vote shares held in their name by going to www.proxyvote.com and using your 16-digit control number included on your proxy card, voting instruction form or notice you received. If you choose any of the first three methods, you must take the described action no later than the beginning of the Diamond S special meeting.

Recommendation of the Diamond S Board and its Reasons for the Transaction (See page 70)

After careful consideration of various factors described in “The Merger — Recommendation of the Diamond S Board and its Reasons for the Transaction,” the Diamond S Board unanimously determined that the merger agreement and the transactions contemplated by the merger agreement (including the merger) are fair to and in the best interests of Diamond S and its shareholders, and the Diamond S Board unanimously recommended that holders of Diamond S common stock vote:

“FOR” the Diamond S Merger Proposal;

“FOR” the Diamond S Advisory Compensation Proposal; and

“FOR” the Diamond S Adjournment Proposal, if necessary to solicit additional proxies if there are not sufficient votes to authorize and approve the merger agreement at the time of the Diamond S special meeting or any adjournment thereof.

Opinion of Diamond S’ Financial Advisor (See page 73)

At the meeting of Diamond S’ board of directors on March 30, 2021 to evaluate and approve the merger, Moelis delivered an oral opinion, which was confirmed by delivery of a written opinion, dated March 30, 2021, addressed to Diamond S’ board of directors to the effect that, as of the date of the opinion and based upon and subject to the assumptions made, procedures followed, matters considered and other limitations set forth in the opinion, the base exchange ratio provided for in the merger pursuant to the merger agreement was fair, from a financial point of view, to the holders of Diamond S common stock, other than INSW and its affiliates.

The full text of Moelis’ written opinion dated March 30, 2021, which sets forth the assumptions made, procedures followed, matters considered and limitations on the review undertaken in connection with the opinion, is attached as Annex C to this joint proxy statement/prospectus and is incorporated herein by reference. Moelis’ opinion was provided for the use and benefit of Diamond S’ board of directors (solely in its capacity as such) in its evaluation of the merger. Moelis’ opinion was limited solely to the fairness, from a financial point of view, to the holders of Diamond S common stock, other than INSW and its affiliates, of the base exchange ratio in the merger. Moelis’ opinion does not address Diamond S’ underlying business decision to effect the merger, or the relative merits of the merger as compared to any alternative business strategies or transactions that might be available with respect to Diamond S. Moelis’ opinion does not constitute a recommendation to any holder of securities as to how such holder should vote or act with respect to the merger or any other matter.

Interests of Diamond S’ Directors and Executive Officers in the Merger (See page 88)

In considering the recommendations of the Diamond S Board that Diamond S shareholders vote “FOR” the Diamond S merger proposal, Diamond S shareholders should be aware that certain directors and executive officers of Diamond S have agreements or arrangements that provide them with interests in the merger that may be different from, or in addition to, the interests of the other shareholders of Diamond S.

TABLE OF CONTENTS

The Diamond S Board was aware of these interests when it approved the merger agreement and the transactions contemplated thereby and recommended that Diamond S shareholders vote “FOR” the Diamond S merger proposal. Such interests include the following and are more fully summarized below:

•

Three directors of Diamond S, including Craig H. Stevenson, Jr., the current chief executive officer of Diamond S, will become directors of the combined company and Mr. Stevenson will serve as a special advisor to INSW’s chief executive officer for a six-month period following the completion of the merger for which he is expected to be paid $500,000;

•

Diamond S’ executive officers have entered into individual agreements that provide for certain severance protections upon a qualifying termination;

•

Diamond S’ executive officers have entered into individual equity award agreements that provide for acceleration of vesting upon a qualifying termination;

•

Diamond S’ directors have entered into individual equity award agreements that provide for acceleration of vesting upon a change in control;

•

Diamond S’ executive officers may enter into new arrangements prior to or following the closing; and

•

Diamond S’ directors and executive officers are entitled to continued indemnification and insurance coverage under the merger agreement.

Treatment of Diamond S’ Equity Awards (See page 97)

As of the effective time, each outstanding restricted stock unit (the “Diamond S RSUs”) under the Diamond S Shipping Inc. 2019 Equity and Incentive Plan, (the “Diamond S Equity Plan”) that is not then vested and does not vest at the effective time will be assumed by INSW and converted into a restricted stock unit award for capital stock of INSW (the “INSW RSUs”) with associated rights to the issuance of additional capital stock of INSW common stock. Each assumed and converted INSW RSU will vest in full (at the target level, with respect to any Diamond S RSUs subject to performance-based vesting criteria) on the holder’s termination of employment without “cause” or for “good reason” (as each such term is defined in the applicable award agreement) within twenty four (24) months following the closing date, and otherwise continue to have, and will be subject to, the same terms and conditions as applied to the applicable Diamond S RSUs immediately prior to the effective time of the merger (but taking into account any changes thereto, including any necessary changes to any issuance provisions, provided for or permitted in the Diamond S Equity Plan, in any applicable award agreement or in such Diamond S RSUs, by reason of the merger agreement or the consummation of the transactions contemplated thereby). To the extent any such Diamond S RSUs are subject to performance vesting or other performance conditions, following the effective time, such awards will be deemed to have achieved at least the target level of performance. As of the effective time, the number of shares of INSW common stock underlying each such INSW RSU as so assumed and converted (rounded (x) up to the nearest whole share if half a share or more or (y) down to the nearest whole share if less than half a share) will equal the product of (i) the number of shares of Diamond S common stock subject to such award, multiplied by (ii) the exchange ratio set forth in the merger agreement.

As of the effective time, INSW will assume and convert into restricted shares of INSW (“INSW Restricted Shares”) each outstanding share of restricted stock (collectively, the “Diamond S Restricted Shares”) granted under the Diamond S Equity Plan that is not then vested and does not vest at the effective time. Each assumed and converted INSW Restricted Share will continue to have, and will be subject to, the same terms and conditions as applied to the applicable Diamond S Restricted Shares immediately prior to the effective time (but taking into account any changes provided for in the Diamond S Equity Plan, in any applicable award agreement or in such Diamond S Restricted Shares, by reason of the merger agreement or the consummation of the transactions contemplated thereby). As of the effective time, the number of shares of INSW common stock underlying each such INSW Restricted Share as so assumed and converted (rounded (x) up to the nearest whole share if half a share or more or (y) down to the nearest whole share if less than half a share) will equal the product of (i) the number of shares of Diamond S common stock subject to such award, multiplied by (ii) the exchange ratio set forth in the merger agreement.

TABLE OF CONTENTS

Treatment of Indebtedness (See page 93)

It is expected that at the completion of the merger, Diamond S will have approximately $625.6 million plus an additional $30 million expected to be drawn down prior to the closing of indebtedness outstanding that INSW will maintain following completion of the merger. The lenders under Diamond S’ applicable credit agreements related to such indebtedness have agreed to waive any event of default that would arise as a result of the merger and waive certain past events of default. For more information see “Indebtedness Amendments.”

It is expected that INSW’s debt will also remain outstanding following completion of the merger.

Ownership of INSW after the Merger (See page 96)

As of the date of this joint proxy statement/prospectus, based on the base exchange ratio, the number of outstanding shares of Diamond S common stock (plus the number of shares underlying outstanding Diamond S equity awards) and the number of outstanding shares of INSW common stock, and assuming that INSW does not declare and pay the INSW FSO dividend, it is estimated that INSW stockholders will own approximately 55.75% and Diamond S shareholders will own approximately 44.25% of the issued and outstanding shares of INSW common stock on a fully diluted basis immediately following the effective time.

Governance of the Combined Company after the Merger (See page 93)

Directors

The merger agreement provides that following the effective time, that the combined company will have a board of directors consisting initially of ten directors comprised of (i) a chairman, designated by INSW, who is expected to be Douglas D. Wheat, (ii) six additional directors, designated by INSW that are reasonably acceptable to Diamond S, one of whom is expected to be Lois K. Zabrocky and the remainder of whom are expected to be current INSW directors, and (iii) three additional directors, designated by Diamond S that are reasonably acceptable to INSW, one of whom is expected to be Craig H. Stevenson, Jr., and the remainder of whom are expected to be current Diamond S directors. In connection with the merger, the Capital stockholders (as defined below) and the WL Ross stockholders (as defined below) agreed to terminate their existing director designation agreements with Diamond S. As a result, no stockholder of the combined company will have a contractual right to designate a director to the board of directors of the combined company.

Officers

The merger agreement provides that the officers of Merger Sub immediately prior to the effective time will become the officers of Diamond S following the effective time.

It is expected that the officers of INSW will remain in place following the effective time. Craig H. Stevenson, Jr., the current chief executive officer of Diamond S, will join the INSW Board and serve as a special advisor to INSW’s chief executive officer for a 6-month period following the completion of the merger. Mr. Stevenson is expected to be paid $500,000 for his role as special advisor.

Conditions to the Completion of the Merger (See page 111)

In addition to the approval of the INSW share issuance proposal by the INSW stockholders and of the Diamond S merger proposal by the Diamond S shareholders, completion of the merger is subject to the satisfaction or (to the extent permitted by law) waiver of a number of other conditions, including:

•

•

the absence of an adverse law or order or injunction prohibiting the merger or the transactions contemplated by the merger agreement, promulgated or issued by a governmental entity of competent jurisdiction;

TABLE OF CONTENTS

the expiration or termination of all applicable waiting periods relating to the merger under the HSR Act;

•

the approval of the listing on the NYSE of the shares of INSW common stock to be issued in the merger as merger consideration, subject to official notice of issuance;

•

the execution and delivery of the A&R debt agreements by the required lenders and the effectiveness of the A&R debt agreements and debt consents (including all amendments contemplated thereunder);

•

the delivery to INSW or Diamond S, as applicable, of a certificate signed on behalf of Diamond S or INSW, as applicable by a duly authorized executive officer of Diamond S or INSW, as applicable, to such effect.

For a more complete description of the conditions to the merger, see “The Merger Agreement — Conditions to the Completion of the Merger.”

Agreement Not to Solicit Other Offers (See page 107)

Diamond S and INSW have each agreed not to, and to cause their respective controlled affiliates and its and their respective officers, directors, employees and representatives not to, directly or indirectly:

•

participate in or engage in any negotiations or discussions (other than to state that they are not permitted to have discussions) regarding, or furnish to any person any nonpublic information relating to Diamond S, INSW or any of their respective subsidiaries in connection with, any inquiry, proposal or offer which constitutes or would be reasonably expected to lead to a competing proposal;

•

except in the event the Diamond S Board or INSW Board has determined in good faith after consultation with outside legal counsel that the failure to take such action would be reasonably likely to constitute a breach of the fiduciary duties of the members of the Diamond S Board or INSW Board under applicable Republic of the Marshall Islands law, waive, terminate, modify or release any person (other than Diamond S or INSW, Merger Sub or any of their respective subsidiaries) from any provision of, or grant any permission, waiver or request under, or fail to enforce, any “standstill” or similar agreement or obligation;

•

approve or recommend, propose publicly to approve or recommend, or fail to timely publicly and without qualification recommend against, any Diamond S or INSW competing proposal and reaffirm the Diamond S Board or INSW Board recommendation, in each case, within ten business days after the Diamond S or INSW competing proposal is made public (including upon request of the other party to do so) (or such fewer number of days as remains prior to the date that is two business days prior to the Diamond S special meeting or INSW special meeting);

•

fail to include the Diamond S Board or INSW Board recommendation in the joint proxy statement/prospectus;

•

withdraw, change, amend, modify or qualify, or otherwise propose publicly to withdraw, change, amend, modify or qualify, in a manner adverse to Diamond S or INSW, their respective board recommendation;

•

enter into any letter of intent or other document or agreement relating to, or any agreement or commitment providing for, any Diamond S or INSW competing proposal, other than a confidentiality agreement contemplated by the merger agreement; or

TABLE OF CONTENTS

•

resolve or agree to do any of the foregoing acts or failures to act described in bullet points four through seven (which is referred to as a board recommendation change).

Notwithstanding these limitations, the merger agreement provides that, if, at any time prior to obtaining the Diamond S shareholder approval or the INSW stockholder approval, Diamond S or INSW receives a proposal that the Diamond S Board or INSW Board, as applicable, determines in good faith (after consultation with its outside counsel and financial advisors) constitutes or would reasonably be expected to result in a “superior proposal” (as defined below) and which did not result from a breach of the non-solicitation obligations set forth in the merger agreement, then Diamond S or INSW, as applicable, may (a) furnish nonpublic information that was previously furnished to the other party to the person making such competing proposal, if, and only if, prior to so furnishing such information, Diamond S or INSW receives from such person an executed confidentiality agreement (and provides a copy of such confidentiality agreement to the other party) and (b) engage in discussions or negotiations with such person with respect to the Diamond S or INSW competing proposal.

The merger agreement also requires each party to (1) notify the other party promptly, and in any event within 24 hours of receipt, of any request for information or proposal relating to an alternative transaction, the material terms and conditions of such request or proposal (including any changes thereto) and the identity of the person making such request or proposal, (2) provide the other party, as soon as reasonably practicable, copies of all correspondence and other written materials exchanged with the person making such request or proposal or its representatives that describes or contains any such request or proposal and (3) keep the other party reasonably informed of the status and details (including amendments or proposed amendments) of any such request or proposal on a reasonably current basis.

For purposes of the merger agreement, a “superior proposal” means any bona fide, unsolicited written proposal (on its most recently amended or modified terms, if amended or modified) made by a third party to enter into an alternative transaction (with references to 20% and 80% being deemed to be replaced with references to 50%) that, taking into account all financial, regulatory, legal and other aspects of such proposal and whether the proposal is fully financed, as well as the identity of the person making the competing proposal, (1) is more favorable to the stockholders of Diamond S or INSW from a financial point of view than the merger, taking into account all relevant factors (including any adjustment to the terms and conditions proposed by Diamond S or INSW in response to such proposal), and (2) is reasonably capable of being completed as proposed on a timely basis.

Prior to Diamond S or INSW making a change of recommendation, Diamond S or INSW will provide the other with five business days’ prior written notice (it being understood and agreed that any material amendment to the applicable competing proposal will require a new notice and an additional two business day period) advising INSW or Diamond S that its board of directors intends to take such action and contemporaneously providing the other party with a copy of the superior proposal, a copy of any proposed agreements for such superior proposal (including any financing commitments related thereto) and indicating the identity of the person making such competing proposal (or, in each case, if not provided in writing, a written summary of the terms thereof), and during such initial five business day or subsequent two business day period, (a) Diamond S or INSW will negotiate, and cause its representatives to negotiate, with the other party and its representatives in good faith (to the extent that the other party wishes to negotiate) to enable the other party to determine whether to propose revisions to the terms of the merger agreement or any other agreement related to the transactions such that the competing proposal would no longer constitute a superior proposal and (b) Diamond S or INSW will consider in good faith any proposal by the other party to amend the terms and conditions of the merger agreement or any other agreement related to the transactions such that such competing proposal would no longer constitute a superior proposal.

For a more complete description of the limitations on the solicitation of transaction proposals from third parties, see “The Merger Agreement — Agreement Not to Solicit Other Offers.”

Termination of the Merger Agreement (See page 112)

The merger agreement may be terminated, and the merger and the other transactions may be abandoned, at any time prior to the completion of the merger under the following circumstances:

if at any time prior to the receipt of the Diamond S shareholder approval or INSW stockholder approval or the Diamond S Board, INSW Board or committees thereof make a change of recommendation or the party willfully breaches the solicitation provisions of the merger agreement (referred to as a “triggering event”) (the party whose triggering event occurs has the right to terminate the agreement);

•

if a governmental entity of competent jurisdiction has issued a final, non-appealable (or no longer appealable) order, injunction, decree, ruling or law in each case permanently restraining, enjoining or otherwise prohibiting the consummation of the merger, provided that this right to terminate the merger is not be available to a party if any such order, injunction, decree, ruling or law was due to the material breach by such party of any representation, warranty, covenant or agreement set forth in the merger agreement; or

Accounting Treatment (See page 94)

Material U.S. Federal Income Tax Consequences of the Merger (See page 151)

TABLE OF CONTENTS

Federal Income Tax Consequences of the Merger”) of Diamond S common stock generally should not recognize any gain or loss for U.S. federal income tax purposes upon the exchange of Diamond S common stock for INSW common stock. However, the completion of the merger is not conditioned upon the receipt of an opinion of counsel to the effect that the merger qualifies for the Intended Tax Treatment. In addition, neither Diamond S nor INSW intends to request a ruling from the IRS regarding the U.S. federal income tax consequences of the merger. Accordingly, no assurance can be given that the IRS will not challenge the Intended Tax Treatment or that a court would not sustain such a challenge. You should read the section entitled “Material U.S. Federal Income Tax Consequences of the Merger” and consult your own tax advisors regarding the U.S. federal income tax consequences of the merger to you in your particular circumstances, as well as tax consequences arising under the laws of any state, local or non-U.S. taxing jurisdiction.

Fractional Shares (See page 97)

No fractional share of INSW common stock will be issued upon the surrender for exchange of certificates or book-entry shares, and such fractional share interests will not entitle the owner thereof to any INSW common stock or to vote or any other rights the rights of a INSW stockholder. Each holder of shares of Diamond S common stock converted pursuant to the merger who would otherwise have been entitled to receive a fraction of a INSW share will receive, in lieu thereof, cash (without interest). It is expected that Cede & Co., as nominee for the Depository Trust Company, will be treated as a single holder for purposes of paying cash in lieu of fractional shares.

Rights of Diamond S Shareholders Will Change as a Result of the Merger (See page 163)

Diamond S shareholders will have different rights once they become INSW stockholders due to differences between the organizational documents of INSW and Diamond S. These differences are described in more detail in the section entitled “Comparison of the Rights of Combined Company Stockholders and Diamond S Shareholders”.

Listing of INSW’s Common Stock; Delisting and Deregistration of Diamond S Common Stock (See page 93)

Under the merger agreement, INSW is required to take all action necessary to cause the shares of INSW common stock issued as merger consideration to be approved on the NYSE prior to the effective time, subject to official notice of issuance. This approval is a condition to the closing of the merger.

If the merger is completed, Diamond S common stock will cease to be listed on the NYSE and Diamond S common stock will be deregistered under the Exchange Act.

Regulatory Matters (See page 94)

Under the HSR Act and related rules, certain transactions, including the merger, may not be completed until notifications have been given and information furnished to the Antitrust Division and the U.S. Federal Trade Commission (“FTC”) and all statutory waiting period requirements have been satisfied. Completion of the merger is subject to the expiration or earlier termination of the applicable waiting period under the HSR Act. INSW and Diamond S each filed their respective HSR Act notification forms on April 21, 2021 and the waiting period under the HSR Act expired on May 21, 2021.

Emerging Growth Company Status

INSW qualifies as an “emerging growth company,” as defined in the Jumpstart Our Business Startups Act of 2012, or the JOBS Act. INSW does not intend to take advantage of the exemptions from various reporting requirements that are applicable to other public companies that are emerging growth companies. Such exemptions include, but are not limited to, scaled disclosure provisions with respect to financial information and executive compensation, compliance with the auditor attestation requirements of Section 404 of the Sarbanes-Oxley Act and the requirements to hold a nonbinding advisory vote on executive compensation and any golden parachute payments not previously approved. Under the JOBS Act, INSW retains the ability to take advantage of these reporting exemptions until it is no longer considered an emerging growth company, which for INSW could be until December 31, 2021, which is the last day of the fiscal year in which the fifth anniversary of INSW's listing took place.

TABLE OF CONTENTS

In addition, Section 107 of the JOBS Act provides that an emerging growth company may take advantage of the extended transition period provided in Section 13(a) of the Exchange Act, for complying with new or revised accounting standards applicable to public companies. In other words, INSW may delay adopting new or revised accounting standards until such time as those standards apply to private companies. INSW has elected not to take advantage of this extended transition period, and our election is irrevocable pursuant to Section 107(b) of the JOBS Act.

S special meeting. The Capital shareholders beneficially owned 6.9% of the outstanding shares of Diamond S common stock as of June 1, 2021. For more information, please see “The Merger Agreement — Capital Support Agreement.”

Capital Termination Agreement (See page 117)

Concurrently with the execution and delivery of the merger agreement, Diamond S entered into a termination agreement with CSMC (the “Capital termination agreement”), dated as of March 30, 2021, whereby, upon the completion of certain events and obligations, including consummation of the merger, the following managerial agreements will be terminated: (i) commercial management agreement, dated as of March 27, 2019, by and between Diamond S and CSMC; (ii) management and services agreement, dated as of March 27, 2019, by and between Diamond S and CSMC; and (iii) each technical management agreement, dated as of March 27, 2019, by and between certain Diamond S vessel-owning subsidiaries and CSMC (also referred to as part II shipman 2009 standard ship management agreement).

Pursuant to the Capital termination agreement, at the effective time, Diamond S will (i) pay, or cause to be paid to CSMC, an amount equal to $30 million minus a certain specified termination fee adjustment amount and (ii) deliver, or cause to be delivered, an amount equal to $4 million minus a certain specified adjustment amount, to be held in escrow and distributed to CSMC on the first day on which certain vessels currently managed by CSMC have been transitioned.

The Capital termination agreement provides that, with respect to each vessel managed by CSMC that is on a time charter, the parties will jointly approach the time charterers to agree to a change in technical management as soon as reasonably practicable following the effective time. However, if an earlier transition cannot be agreed upon, then CSMC will provide technical management services to such vessel through the end of the time charter and, if necessary, for a period of time until a transition is reasonably practicable. In addition, CSMC has agreed to provide (i) commercial management services until each such vessel is transitioned and (ii) the certain additional services outlined in the Capital termination agreement. With respect to vessels not on a time charter, the parties to the Capital termination agreement have agreed to use their reasonable best efforts to (A) commence planning and coordination for the transition of commercial and technical management of such vessels that are not on a time charter from CSMC and/or its affiliates and (B) facilitate such transition on the earliest practical date after the effective time.

No Dissenters or Appraisal Rights (See page 95)

Holders of Diamond S common stock and holders of INSW common stock are not entitled to appraisal rights under the BCA with respect to the merger. For more information, see “The Merger — No Dissenters or Appraisal Rights.”

RISK FACTORS

You should consider carefully the following risk factors, as well as the other information set forth in and incorporated by reference into this joint proxy statement/prospectus, before making a decision on the Diamond S merger proposal, the INSW share issuance proposal or the other proposals presented herein, as applicable. As a INSW stockholder following completion of the merger, Diamond S shareholders will be subject to all risks inherent in the pre-merger businesses of both INSW and Diamond S. The market value of the shares of INSW common stock to Diamond S shareholders will reflect the performance of the business relative to, among other things, that of the competitors of INSW and Diamond S and general economic, market and industry conditions. The value of your investment may increase or may decline and could result in a loss. You should carefully consider the following factors as well as the other information contained in and incorporated by reference into this joint proxy statement/prospectus. For information about the filings incorporated by reference in this joint proxy statement/prospectus, see the section entitled “Where You Can Find Additional Information.”

Risks Related to the Merger

Because the market value of shares of INSW common stock that Diamond S shareholders will receive in the merger may fluctuate, Diamond S shareholders cannot be sure of the market value of the merger consideration that they will receive in the merger.

Pursuant to the merger agreement, each share of Diamond S common stock will be cancelled in exchange for the right to receive 0.55375 shares of INSW common stock. Accordingly, the merger consideration that Diamond S shareholders will receive upon completion of the merger is a fixed number of shares of INSW common stock (except to the extent of any cash received in lieu of a fractional shares of INSW common stock and except if INSW sells any interests in the FSO Joint Ventures prior to the closing and pays a dividend from the proceeds), not a number of shares that will be determined based on a fixed market value. The market value of shares of INSW common stock and the market value of shares of Diamond S common stock at the effective time may vary significantly from their respective values on the date that the merger agreement was executed or at other dates, such as the date of this joint proxy statement/prospectus or the date of the Diamond S special meeting. Changes in share price may result from a variety of factors, including, among others, changes in INSW’s or Diamond S’ respective businesses, operations or prospects, regulatory considerations, governmental actions, legal proceedings, certain permitted dilutive share issuances and general business, market, industry or political or economic conditions. Market assessments of the benefits of the merger, the likelihood that the merger will be completed and general and industry-specific market and economic conditions may also have an effect on the market price of shares of INSW common stock and shares of Diamond S common stock. Many of these factors are beyond Diamond S’ or INSW’s control. The merger consideration will not be adjusted to reflect any changes in the market value of shares of INSW common stock or the market value of shares of Diamond S common stock or the number of shares of Diamond S common stock or number of shares of INSW common stock outstanding at the closing. Therefore, the aggregate market value of the shares of INSW common stock that a Diamond S shareholder is entitled to receive at the time that the merger is completed could vary significantly from the value of the equivalent shares of INSW common stock on the date of this joint proxy statement/prospectus or the date of the Diamond S special meeting and, at the time of the Diamond S special meeting, Diamond S shareholders will not know or be able to calculate the value of the merger consideration they would receive upon completion of the merger. Neither INSW nor Diamond S is permitted to terminate the merger agreement solely because of changes in the market prices of shares of Diamond S common stock or shares of INSW common stock. Shareholders are urged to obtain current market quotations for shares of INSW common stock and shares of Diamond S common stock. See the section entitled “Comparative Per Share Market Price and Dividend Information” for additional information on the historical market values of shares of INSW common stock and shares of Diamond S common stock.

The completion of the merger is subject to a number of conditions and the merger agreement may be terminated in accordance with its terms. As a result, there is no assurance when or if the merger will be completed.

The completion of the merger is subject to the satisfaction or waiver of a number of conditions as set forth in the merger agreement. These include, among others, at or prior to the effective time, (a) the adoption of the merger agreement at the Diamond S special meeting by holders of a majority of the outstanding

TABLE OF CONTENTS

shares of Diamond S common stock; (b) the approval of the issuance of the merger consideration by a majority of the shares of INSW common stock present and entitled to vote at the INSW special meeting; (c) the effectiveness of the registration statement on Form S-4 of which this joint proxy statement/prospectus is a part and the absence of an actual or threatened proceeding by the SEC to stop the effectiveness of the registration statement on Form S-4; (d) no governmental entity of competent jurisdiction having enacted any law, or having issued any injunction, prohibiting, making illegal or preventing the consummation of the merger; (e) the expiration or termination of all applicable waiting periods (and extensions thereof) under the HSR Act; (f) the approval for listing of the shares of INSW common stock issued as merger consideration on the NYSE, subject to official notice of issuance; (g) the entry into, and effectiveness of the A&R debt agreements and the debt consents (including the amendments contemplated thereunder); (h) the accuracy of the representations and warranties contained in the merger agreement (subject to specified materiality qualifiers); and (i) compliance with the pre-closing covenants and agreements in the merger agreement in all material respects. There can be no assurance as to when these conditions will be satisfied or waived, if at all, or that other events will not intervene to delay or result in the failure to close the merger.

In addition, if the merger is not completed by the outside date of November 1, 2021, either INSW or Diamond S may choose to terminate the merger agreement. However, this right to terminate the merger agreement will not be available to INSW or Diamond S if such party has materially breached the merger agreement and the breach is the cause of or resulted in the failure of the merger to be completed prior to the outside date. INSW or Diamond S may elect to terminate the merger agreement in certain other circumstances, and INSW and Diamond S can mutually decide to terminate the merger agreement at any time prior to the effective time, before or after the required approval by the INSW stockholders or the Diamond S shareholders. If the merger agreement is terminated, INSW and Diamond S may incur substantial fees in connection with the termination of the merger agreement and will not recognize the anticipated benefits of the merger. For more information, see the sections entitled “The Merger Agreement — Conditions to the Completion of the Merger” and “The Merger Agreement — Termination of the Merger Agreement.”

Delay or failure by Diamond S or INSW to satisfy the conditions under the A&R debt agreements may delay or prevent the closing of the merger.

A condition to the completion of the merger is that the required lenders under Diamond S’ existing $525 million credit facility and its $360 million credit facility must have executed and delivered amendment and restatements of such credit facilities that continue to be effective as of the closing of the merger. In addition, the required lenders under such credit facilities and the $66 million credit facility of the NT Suez joint venture waived events of default as a result of the merger and certain past events of default, which consents must remain in effect as a condition to completion of the merger. Although the required lenders have executed and delivered the A&R debt agreements, there are conditions precedent under the A&R debt agreements that will need to be satisfied prior to the amendments contemplated under the A&R debt agreement coming into effect. As a result, completion of the merger may be delayed or prevented. For more information, see the section entitled Indebtedness Amendments.”

The completion of the merger is subject to receipt of consents, orders and approvals from regulatory and governmental entities, which may delay, or result in conditions or restrictions on, the closing of the merger or prevent the closing of the merger entirely.

The completion of the merger is subject to the satisfaction or waiver of a number of conditions relating to the receipt of consents, order and approvals from regulatory and governmental entities under the HSR Act (the waiting period for which expired on May 21, 2021), as well as the absence of any injunctions prohibiting the merger. In addition, the Form S-4 must be declared effective by the SEC. As a result of these conditions, the merger may not be completed until notifications have been given and information furnished to the Antitrust Division of the FTC and all statutory waiting period requirements have been satisfied. Completion of the merger is subject to the expiration or earlier termination of the applicable waiting period under the HSR Act as described in the section “The Merger — Regulatory Matters.” INSW and Diamond S have made the required filings and submissions with governmental entities and the waiting period under the HSR Act expired on May 21, 2021. Even if all required consents, orders and approvals are obtained and all necessary conditions are satisfied, the consents, orders and approvals may include restrictive terms and conditions. Regulatory and governmental entities may impose conditions on the granting of

TABLE OF CONTENTS

consents, orders and approvals, and if regulatory and governmental entities seek to impose conditions, lengthy negotiations may ensue among the regulatory or governmental entities, INSW and Diamond S. These conditions and the process of obtaining these consents, orders and approvals could delay the completion of the merger and any such conditions may not be satisfied for an extended period of time following the Diamond S special meeting and INSW special meeting, if at all.

The conditions imposed by regulatory and governmental entities on the granting of consents, orders and approvals may also require divestitures relating to the divisions, operations or assets of INSW and Diamond S, may impose limitations or costs, and may place restrictions on the conduct of INSW’s or Diamond S’ business. Compliance with these conditions may reduce the anticipated benefits of the merger, which could also have an adverse effect on the combined company’s business, cash flows and results of operations, and neither INSW nor Diamond S can predict, what, if any, changes may be required by regulatory or governmental authorities whose consents, orders or approvals are required.

INSW or Diamond S may waive one or more of the closing conditions without re-soliciting stockholder approval.

INSW or Diamond S may determine to waive, in whole or in part, one or more of the conditions to its obligations to consummate the merger. INSW or Diamond S currently expect to evaluate the materiality of any waiver and its effect on INSW stockholders or Diamond S shareholders, as applicable, in light of the facts and circumstances at the time to determine whether any amendment of this joint proxy statement/prospectus or any re-solicitation of proxies or voting cards is required in light of such waiver. Any determination whether to waive any condition to the merger or as to re-soliciting shareholder approval or amending this joint proxy statement/prospectus as a result of a waiver will be made by INSW or Diamond S, as applicable, at the time of such waiver based on the facts and circumstances as they exist at that time.

The termination of the merger agreement could negatively impact Diamond S and/or INSW and could result in payment of a termination fee.

If the merger agreement is terminated in accordance with its terms and the merger is not consummated, the ongoing businesses of Diamond S or and INSW may be adversely affected by a variety of factors. Diamond S and INSW’s respective businesses may be adversely impacted by the failure to pursue other beneficial opportunities during the pendency of the merger, by the failure to obtain the anticipated benefits of completing the merger, by payment of certain costs relating to the merger, and by the focus of their respective managements on the merger for an extended period of time rather than on management opportunities or other issues. The market price of shares of Diamond S common stock or shares of INSW common stock may decline as a result of any such failures to the extent that the current market prices reflect a market assumption that the merger will be completed.

Diamond S may be required to pay INSW a termination fee of $17 million if the merger agreement is terminated under certain circumstances specified in the merger agreement relating to third party offers to acquire Diamond S or a third party acquisition of Diamond S or a breach of Diamond S’ obligation not to solicit third party offers or its obligations with respect to holding a meeting of its shareholders in connection with the merger. INSW may be required to pay Diamond S a termination fee of $19 million if the merger agreement is terminated under certain circumstances specified in the merger agreement relating to third party offers to acquire INSW or a third party acquisition of INSW or a breach of INSW’s obligation not to solicit third party offers or its obligations with respect to holding a meeting of its stockholders in connection with the merger. If the merger agreement is terminated and Diamond S or INSW determines to seek another business combination or strategic opportunity, Diamond S or INSW may not be able to negotiate a transaction with another party on terms comparable to, or better than, the terms of the merger. For more information, see the sections entitled “The Merger Agreement — Agreement Not to Solicit Other Offers” and “The Merger Agreement — Expenses and Termination Fee.”

The pendency of the merger could adversely affect INSW’s and Diamond S’ respective businesses, results of operations and financial condition.

Beginning at the time of the execution of the merger agreement and continuing until the merger closes or the merger agreement is terminated in accordance with its terms, the pendency of the merger could cause

TABLE OF CONTENTS

disruptions in and create uncertainty surrounding INSW’s and Diamond S’ businesses, including affecting INSW’s and Diamond S’ relationships with their existing and future customers, suppliers, partners in the business community and employees. This could have an adverse effect on INSW’s and Diamond S’ respective businesses, results of operations and financial condition, as well as the market prices of their shares, regardless of whether the merger is completed. In particular, INSW and Diamond S could potentially lose important personnel who decide to pursue other opportunities as a result of the merger. Any adverse effect could be exacerbated by a prolonged delay in closing the merger or if Diamond S and INSW are unable to decide quickly on the business direction or strategy of the combined company. INSW and Diamond S could also potentially lose customers or suppliers, existing customers or suppliers may seek to change their existing business relationships or renegotiate their contracts with INSW or Diamond S or defer decisions concerning INSW or Diamond S, and potential customers or suppliers could defer entering into contracts with INSW or Diamond S, each as a result of uncertainty relating to the merger. In addition, in an effort to complete the merger, INSW and Diamond S have expended, and will continue to expend, significant management resources, which are being diverted from INSW’s and Diamond S’ day-to-day operations, and significant demands are being, and will continue to be, placed on the managerial, operational and financial personnel and systems of INSW and Diamond S in connection with efforts to complete the merger.

The termination of the Capital relationship could adversely affect Diamond S, or following the closing of the merger, the combined company.

Twenty-three of Diamond S’ 64 vessels are currently managed by CSMC. In connection with the merger, CSMC’s management agreements with Diamond S will terminate and CSMC, Diamond S and INSW will transition management of such vessels to Diamond S or INSW or a new third party manager. In connection with the termination of CSMC’s management agreements, Diamond S will pay CSMC, or cause to be paid to CSMC, an amount equal to $30 million minus a certain specified termination fee adjustment amount and deliver, or cause to be delivered, an amount equal to $4 million minus a certain specified termination fee adjustment amount, to be held in escrow and distributed to CSMC on the first day on which certain vessels currently managed by CSMC have been transitioned. CSMC is also entitled to certain additional fees while it continues to manage the vessels and is entitled to reimbursement of its legal fees up to $200,000.

The termination of the CSMC management agreements may adversely affect Diamond S because it may be difficult to replace CSMC’s expertise and knowledge in managing such vessels. In addition, the process of transitioning management from CSMC may be time consuming for management of Diamond S and INSW and may involve the incurrence of one-time costs. The termination fee payable to CSMC to terminate the management agreements will reduce the cash on hand of the combined company. The majority of the termination fee is payable to CSMC at closing of the merger, prior to the completion of the transition of management of the relevant vessels. Post-closing of the merger, CSMC will have ongoing obligations related to management of the vessels and the transition after receiving the majority of the termination fee. The transition of management of these vessels will be more difficult during the COVID-19 pandemic. For more information, see the section entitled “The Merger Agreement — Capital Termination Agreement.”

Third parties may terminate, alter or decline to renew existing contracts or relationships with INSW or Diamond S.

Each of INSW and Diamond S has contracts with customers, suppliers, vendors, distributors, landlords, lenders, licensors, joint venture partners and other business partners and these contracts may require INSW or Diamond S, as applicable, to obtain consent from these other parties in connection with the merger. If these consents cannot be obtained, the counterparties to these contracts (and other third parties with which INSW and/or Diamond S currently have relationships, even if not contractual) may have the ability to terminate, reduce the scope of or otherwise materially adversely alter their relationships or terms of such contracts with either or both parties in anticipation of the merger, or with the combined company following the merger. In addition, counterparties to agreements that are near termination may determine not to renew such agreements as a result of the merger or seek amendments to terms of existing contracts. The pursuit of such termination rights or amendments, or a determination not to renew such agreements, may result in INSW, Diamond S or the combined company suffering a loss of potential future revenue, incurring

TABLE OF CONTENTS

liabilities in connection with breaches of agreements or losing rights that are material to its business. Any such disruptions could limit the combined company’s ability to achieve the anticipated benefits of the merger. The adverse effect of such disruptions could also be exacerbated by a delay in the completion of the merger or the termination of the merger agreement.

INSW and Diamond S will incur substantial transaction fees and costs in connection with the merger.

INSW and Diamond S have incurred and expect to continue to incur additional material expenses in connection with the merger and the completion of the transactions contemplated by the merger agreement, including costs relating to obtaining required INSW stockholder and Diamond S shareholder approvals and regulatory approvals, as well as costs related to the amendment and restatement of Diamond S’ existing debt agreements and payment of a termination fee to CSMC, as well as reimbursement of certain legal fees of CSMC. INSW and Diamond S have incurred significant legal, financial and other advisory services fees in connection with the process of negotiating and evaluating the terms of the merger and will continue to incur significant costs, such as legal, accounting, financial advisory, filing and printing fees, prior to and in connection with the completion of the merger. Additional significant unanticipated costs may be incurred in the course of integrating the businesses of INSW and Diamond S after completion of the merger. Irrespective of whether the merger is completed, INSW and Diamond S will need to pay certain costs relating to the merger incurred prior to the date the merger was abandoned, including legal, accounting, financial advisory, filing and printing fees. These costs may be significant and could have an adverse effect on the parties’ future results of operations, cash flows and financial condition.

Each party may not have discovered certain liabilities of the other party or other factors that may adversely affect the future financial performance of the relevant company.

In the course of the due diligence review of INSW that Diamond S conducted prior to the execution of the merger agreement, and the due diligence review of Diamond S that INSW conducted prior to the execution of the merger agreement, the party conducting due diligence may not have discovered, or may have been unable to quantify, certain liabilities of the other party or other factors that may have an adverse effect on the business, results of operations, financial condition and cash flows of the other party or the combined company after the consummation of the merger or on the value of the shares of INSW common stock or the shares Diamond S common stock after the consummation of the merger. Neither party’s existing stockholders will be indemnified or otherwise compensated for any of these liabilities or other adverse effects resulting from other factors.

While the merger agreement is in effect, INSW and Diamond S are subject to restrictions on their respective business activities. These provisions may discourage a potential competing transaction counterparty from making a favorable alternative transaction proposal.

Under the merger agreement, each of INSW and Diamond S, subject to certain exceptions, is subject to a range of restrictions on the conduct of its business and generally must operate its business in the ordinary course prior to completing the merger (unless INSW or Diamond S obtains the other’s consent, which is not to be unreasonably withheld, conditioned or delayed). In addition, consent of the other party (not to be unreasonably withheld, conditioned or delayed) is required to take a number of enumerated non-ordinary course actions. These restrictions may constrain INSW’s and Diamond S’ ability to pursue certain business strategies. The restrictions may also prevent INSW and Diamond S from pursuing otherwise attractive business opportunities, making acquisitions and investments or making other changes to their respective businesses prior to the completion of the merger or the termination of the merger agreement. Any such lost opportunities may reduce either or both companies’ competiveness or efficiency and could lead to an adverse effect on INSW’s and Diamond S’ business, financial results, financial condition or share prices. These interests are described in more detail in the section entitled “The Merger Agreement — Covenants and Agreements — Conduct of Business.”

In addition, the merger agreement prohibits INSW and Diamond S, subject to certain exceptions, from (a) soliciting, initiating or knowingly encouraging or knowingly facilitating any inquiry, proposal or offer, or the making, submission, modification or amendment or announcement of any inquiry, proposal or offer (including any inquiry, proposal or offer to their respective stockholders or shareholders, as applicable) which

TABLE OF CONTENTS

constitutes, or would be reasonably expected to lead to, a competing acquisition proposal; (b) participating in or engaging in any negotiations or discussions regarding, or furnishing to any person any nonpublic information in connection with any inquiry, proposal or offer which constitutes, or would be reasonably expected to lead to, a competing acquisition proposal; (c) waiving, terminating, modifying or releasing any person (other than Diamond S, INSW, Merger Sub and their respective affiliates, as applicable) from any provision of, or granting any permission, waiver or request under, or failing to enforce, any “standstill” or similar agreement or obligation; (d) approving or recommending, proposing publicly to approve or recommend, or failing to timely recommend against, any competing acquisition proposal; (e) withdrawing, changing, amending, modifying or qualifying, or otherwise proposing publicly to withdraw, change, amend, modify or qualify, in a manner adverse to INSW or Diamond S, as applicable, the Diamond S Board’s or INSW Board’s recommendation to their respective stockholders or shareholders, as applicable, to approve the INSW share issuance proposal or the Diamond S merger agreement proposal, as applicable; (f) entering into any letter of intent or other document or agreement relating to, or any agreement or commitment providing for, any competing acquisition proposal; or (g) resolving or agreeing to do any of the foregoing. In addition, following receipt by either party of a proposal that constitutes a “superior proposal,” the other party will have the ability to modify the terms of the merger agreement before the other party’s board may modify or qualify the terms of its recommendation. These provisions may limit Diamond S’ ability to pursue offers from third parties that could result in greater value to Diamond S shareholders than they would receive in the merger. The $17 million termination fee payable to INSW may also discourage third parties from pursuing an acquisition proposal with respect to Diamond S and the $19 million termination fee payable to Diamond S may also discourage third parties from pursuing an acquisition proposal with respect to INSW.

The merger agreement also limits each party’s ability to pay dividends. Diamond S is generally prohibited from paying dividends or effecting share repurchases. INSW may only make the INSW special dividend, its regular quarterly dividend of up to $0.06 per share and the INSW FSO dividend following the sale of any of INSW’s interest in, or the assets of, the FSO Joint Ventures. There is no guarantee that any dividends will be paid by INSW to its stockholders, including any such dividends that are permitted under the merger agreement.

If the merger does not qualify for the Intended Tax Treatment, holders of Diamond S common stock may be required to recognize gain for U.S. federal income tax purposes in the merger and may be required to pay substantial U.S. federal income taxes.

It is intended that, for U.S. federal income tax purposes, the merger qualifies for the Intended Tax Treatment. If the merger so qualifies, U.S. Holders (as defined below in the section entitled “Material U.S. Federal Income Tax Consequences of the Merger”) of Diamond S common stock generally should not recognize any gain or loss for U.S. federal income tax purposes upon the exchange of Diamond S common stock for INSW common stock. However, qualification of the merger for the Intended Tax Treatment depends on many factors, and neither INSW nor Diamond S is making any representation as to whether the merger qualifies for the Intended Tax Treatment. Moreover, the completion of the merger is not conditioned upon the receipt of an opinion of counsel to the effect that the merger qualifies for the Intended Tax Treatment, and neither Diamond S nor INSW intends to request a ruling from the IRS regarding the U.S. federal income tax consequences of the merger. Accordingly, no assurance can be given that the IRS will not challenge the Intended Tax Treatment or that a court would not sustain such a challenge. If the IRS or a court determines that the merger fails to qualify for the Intended Tax Treatment, upon the exchange of Diamond S common stock for INSW common stock pursuant to the merger, a holder of Diamond S common stock generally would recognize taxable gain or loss as if it sold its Diamond S common stock. You should read the section entitled “Material U.S. Federal Income Tax Consequences of the Merger” and consult your own tax advisors regarding the U.S. federal income tax consequences of the merger to you in your particular circumstances, as well as tax consequences arising under the laws of any state, local or non-U.S. taxing jurisdiction.

In addition, although Diamond S does not believe it is currently a “passive foreign investment company” (a “PFIC”) within the meaning of Section 1297 of the Code for U.S. federal income tax purposes, if Diamond S is now or previously was for any year a PFIC, the merger may, in certain circumstances, be taxable to U.S. Holders of Diamond S common stock who owned equity interests in Diamond S while Diamond S

TABLE OF CONTENTS

was a PFIC even if the merger qualifies for the Intended Tax Treatment. U.S. Holders of Diamond S common stock who believe they may have held equity interests of Diamond S while it was a PFIC are urged to consult with their own tax advisors regarding the consequences to them of the merger.

Directors and executive officers of INSW and Diamond S may have interests in the merger that differ from, are in addition to, or conflict with, the interests of their respective stockholders or shareholders, as applicable, generally.

The directors and executive officers of INSW and Diamond S negotiated the terms of the merger agreement and the INSW Board and Diamond S Board recommended that their respective stockholders and shareholders vote in favor of the proposals set forth herein, including the INSW share issuance proposal and Diamond S merger proposal, as applicable. Some of these directors and executive officers may have interests in the merger that are different from, or in addition to those of INSW stockholders and Diamond S shareholders generally. Additional interests of directors or executive officers of INSW include the continued service of certain directors or executive officers of INSW as directors or executive officers of the combined company and are more fully summarized below. Additional interests of the directors and executive officers of Diamond S include the following and are more fully summarized below:

•

Three directors of Diamond S, including Mr. Stevenson, will become directors of the combined company and Mr. Stevenson will serve as a special advisor to the combined company’s chief executive officer for a six-month period following the closing of the merger for which he is expected to be paid $500,000;

•

Diamond S’ executive officers have entered into individual agreements that provide for certain severance protections upon a qualifying termination;

•

Diamond S’ executive officers have entered into individual equity award agreements that provide for acceleration of vesting upon a qualifying termination;

•

Diamond S’ directors have entered into individual equity award agreements that provide for acceleration of vesting upon a change in control;

•

Diamond S’ executive officers may enter into new arrangements prior to or following the closing; and

•

Diamond S’ directors and executive officers are entitled to continued indemnification and insurance coverage under the merger agreement.

INSW stockholders and Diamond S shareholders should be aware of these interests when they consider the recommendation of the INSW Board that the INSW stockholders vote in favor of the proposals set forth herein, including the INSW share issuance proposal, and the recommendation of the Diamond S Board that Diamond S shareholders vote in favor of the proposals set forth herein, including the Diamond S merger proposal. The INSW Board was aware of these interests when it determined that the merger agreement and the transactions contemplated thereby were advisable and fair to, and in the best interests of, the INSW stockholders and recommended that the INSW stockholders vote “FOR” the proposals set forth herein, including the INSW share issuance proposal, and the Diamond S Board was aware of these interests when it determined that the merger agreement and the transactions contemplated thereby were advisable and fair to, and in the best interests of, the Diamond S shareholders and recommended that the Diamond S shareholders vote “FOR” the proposals set forth herein, including the Diamond S merger proposal. These interests are described in more detail in the sections entitled “The Merger — Interests of Certain of INSW’s Directors and Executive Officers in the Merger” and “The Merger — Interests of Diamond S’ Directors and Executive Officers in the Merger.”

Uncertainties associated with the merger may cause a loss of management personnel and other key employees, which could adversely affect the future business and operations of the combined company following completion of the merger.

Each of Diamond S and INSW are dependent on the experience and industry knowledge of their officers and other key employees to execute their business plans. The combined company’s success after the completion of the merger will depend in part upon the ability of the combined company to retain certain key

TABLE OF CONTENTS

management personnel and employees of Diamond S and INSW. Although Craig H. Stevenson, Jr. will join the board of INSW and serve as a special advisor to the combined company’s chief executive officer for a six-month period following the closing of the merger to ensure a smooth transition, it is expected that other executive officers of Diamond S will not serve the combined company. Prior to the completion of the merger, current and prospective employees of Diamond S and INSW may experience uncertainty about their roles following the completion of the transactions, which may have an adverse effect on the ability of the combined company to attract or retain key management and other key personnel. In addition, no assurance can be given that the combined company, after the completion of the merger, will be able to attract or retain key management personnel and other key employees to the same extent that INSW and Diamond S have previously been able to attract or retain their own employees.

The unaudited pro forma combined financial information in this joint proxy statement/prospectus is presented for illustrative purposes only and may not be reflective of the operating results and financial condition of the combined company following completion of the merger.

The unaudited pro forma combined financial information in this joint proxy statement/prospectus is presented for illustrative purposes only and is not necessarily indicative of what the combined company’s actual financial position or results of operations would have been had the merger been completed on the dates indicated. The unaudited pro forma combined financial information is subject to a number of assumptions, and does not take into account any synergies related to the proposed transaction. Further, the combined company’s actual results and financial position after the merger may differ materially and adversely from the unaudited pro forma combined financial data that is included in this joint proxy statement/prospectus. The unaudited pro forma combined financial information has been prepared with the expectation, as of the date of this joint proxy statement/prospectus, that INSW will be identified as the acquiror under GAAP and reflects adjustments based upon preliminary estimates of the fair value of assets to be acquired and liabilities to be assumed. The final asset acquisition accounting will be based upon the actual purchase price and the fair value of the assets and liabilities of the party that is determined to be the acquiree under GAAP as of the date of the completion of the merger. Accordingly, the final acquisition accounting may differ materially from the unaudited pro forma combined financial information reflected in this joint proxy statement/prospectus. For further discussion, see “Unaudited Pro Forma Condensed Combined Financial Information.”

Diamond S shareholders and INSW stockholders will have a reduced ownership and voting interest after the merger and will have less influence over the management of the combined organization.

Diamond S shareholders currently have the right to vote in the election of the Diamond S Board and on certain other matters affecting Diamond S. Upon the completion of the merger on the terms set forth in the merger agreement, each holder of shares of Diamond S common stock that receives shares of INSW common stock will become a stockholder of INSW with a percentage ownership of the combined organization that is smaller than the holder’s current percentage ownership of Diamond S. Similarly, holders of shares of INSW common stock will be diluted as a result of the issuance of shares to Diamond S shareholders as the merger consideration. It is expected that the former shareholders of Diamond S, as a group, will receive shares in the merger constituting approximately 44.25% of the outstanding shares of INSW common stock immediately following the merger and former stockholders of INSW will retain approximately 55.75% of the outstanding shares of INSW common stock immediately following the merger. In addition, as of immediately following the merger, former directors of Diamond S will constitute three of the 10 members of the combined company’s board of directors. As a result, holders of shares of Diamond S common stock, as a group, will have significantly less influence on the management and policies of INSW than they now have on the management and policies of Diamond S.

INSW and Diamond S may be targets of shareholder class actions or derivative actions, which could result in substantial costs and may delay or prevent the merger from being completed.

Shareholder class action lawsuits or derivative lawsuits are often brought against companies that have entered into merger agreements. Even if the lawsuits are without merit, defending against these claims can result in substantial costs and divert management time and resources. Additionally, if a plaintiff is successful in obtaining an injunction prohibiting consummation of the merger, then that injunction may delay or prevent the merger from being completed.

TABLE OF CONTENTS

One of the conditions to consummating the merger is that no governmental entity has enacted or promulgated any statute, rule, regulation or law that prohibits or makes illegal the consummation of the merger and that there is no order or injunction issued by any governmental entity in effect preventing the consummation of the merger. Consequently, if a claimant secures injunctive or other relief prohibiting, delaying or otherwise adversely affecting INSW’s or Diamond S’ ability to complete the merger on the terms contemplated by the merger agreement, then such law or injunctive or other relief may prevent consummation of the merger in a timely manner or at all.

Each of the Diamond S Board and the INSW Board has not requested, and does not anticipate requesting, an updated opinion from its respective financial advisor reflecting changes in circumstances that may occur between the signing of the merger agreement and the completion of the merger.

Consistent with market practice, the Diamond S Board has not obtained an updated opinion from its financial advisor, Moelis, as of the date of this joint proxy statement/prospectus, and does not expect to receive an updated, revised or reaffirmed opinion prior to the completion of the merger. Similarly, the INSW Board has not requested, and does not anticipate requesting, an updated opinion from its financial advisor, Jefferies, as of the date of this proxy statement/prospectus, and does not expect to receive an updated, revised or reaffirmed opinion prior to the completion of the merger. Changes in the operations and prospects of INSW and Diamond S, general market and economic conditions and other factors that may be beyond the control of INSW and Diamond S, and on which each company’s respective financial advisor’s opinion was based, may significantly alter the value of INSW and Diamond S or the market price of shares of INSW common stock and shares of Diamond S common stock by the time the merger is completed. Each of Diamond S’ financial advisor’s or INSW’s financial advisor’s respective opinions do not speak as of the time the merger will be completed or as of any date other than the date of such opinions. The Diamond S Board’s recommendation that Diamond S shareholders vote “FOR” the Diamond S merger proposal, and the INSW Board’s recommendation that INSW stockholders vote “FOR” the INSW share issuance proposal, however, is made as of the date of this joint proxy statement/prospectus. For a description of the opinions that the INSW Board and Diamond S Board received from their respective financial advisors, see the sections entitled “The Merger — Opinion of Diamond S’ Financial Advisor” and “The Merger — Opinion of INSW’s Financial Advisor.”

INSW stockholders and Diamond S shareholders will not be entitled to appraisal rights under Marshall Islands law in connection with the merger.

Appraisal rights are statutory rights that, if applicable under law, enable stockholders to dissent from an extraordinary transaction, such as a merger, and to demand that the corporation pay the fair value for their shares as determined by a court in a judicial proceeding instead of receiving the consideration offered to stockholders in connection with the extraordinary transaction. Under the BCA, stockholders of a Marshall Islands corporation do not have appraisal rights if the common stock they hold, as of the record date for determining the stockholders entitled to vote at a meeting of stockholders to act upon a merger, is listed on a national securities exchange. Since shares of Diamond S common stock are listed on the NYSE, a national securities exchange, on the record date for the Diamond S special meeting, Diamond S shareholders will not be entitled to appraisal rights in connection with the merger.

Because INSW is not a constituent company in the merger, its stockholders will not be entitled to appraisal rights in connection with the merger.

Risks Related to Diamond S’ Business

Risks Related to INSW’s Business

You should read and consider the risk factors specific to INSW’s business that will also affect the combined company after completion of the merger. These risks are described in “Part I. Item 1A. Risk Factors” of INSW’s Annual Report on Form 10 K for the fiscal year ended December 31, 2020, which are incorporated by reference into this proxy statement/prospectus, and in other documents that are incorporated by reference into this proxy statement/prospectus.

Risks Related to the Combined Company

The combined company may not realize all of the anticipated benefits of the merger or those benefits may take longer to realize than expected. The combined company may also encounter significant difficulties in integrating the two businesses.

INSW anticipates that the merger will generate estimated annual cost synergies in excess of $23 million and revenue synergies of $9 million, which are expected to be fully realizable within 2022. However, there is a risk that some or all of the expected benefits of the merger may fail to materialize, or may not occur within the time periods anticipated by INSW and Diamond S. The realization of the anticipated benefits may be affected by a number of factors, many of which will be beyond the control of INSW. The challenge of combining previously independent businesses makes evaluating the business and future financial prospects of INSW following the merger difficult. INSW and Diamond S have operated and, until the completion of the merger, will continue to operate, independently. The past financial performance of each of INSW and Diamond S may not be indicative of the future financial performance of the combined company. Realization of the anticipated benefits in the merger will depend, in part, on the ability of INSW and Diamond S to successfully integrate their operations in an efficient and timely manner and without adversely affecting current revenues and investments in future growth.

The combined company will be required to devote significant management attention and resources to integrating its business practices and support functions, including aligning policies and internal controls of the two companies. The diversion of management’s attention and any delays or difficulties encountered in connection with the merger and the subsequent coordination of the two companies’ operations could have an adverse effect on the business, financial results, financial condition or the share price of the combined company following the merger. The coordination process may also result in additional and unforeseen expenses.

The forecasts considered by Diamond S and INSW may not be realized, which may adversely affect the market price of shares of the combined company’s common stock.

In connection with their respective evaluations of the merger, the Diamond S Board and INSW Board each relied on, among other things, internal stand-alone forecasts prepared by Diamond S and INSW management, respectively (for more information see the section entitled “Certain Unaudited Forecasted Financial Information of INSW” and “Certain Unaudited Forecasted Financial Information of Diamond S”). These forecasts were not prepared with a view towards public disclosure or compliance with the published guidelines of the SEC or the guidelines established by the American Institute of Certified Public Accountants for preparation and presentation of financial forecasts. These projections are inherently based on estimates and assumptions that are subject to the judgment of those preparing them. These projections are also subject to significant economic, competitive, industry and other uncertainties and contingencies, all of which are difficult or impossible to predict and many of which are beyond the control of INSW and Diamond S. INSW’s or Diamond S’ financial condition or results of operations may not be consistent with those set forth in the forecasts, which could have a material impact on the market price of shares of the combined company’s common stock following the merger.

Disruption in the financial markets could affect the combined company’s ability to refinance existing obligations on favorable terms, or at all.

INSW and Diamond S both have existing debt obligations (and Diamond S’ debt for borrowed money will remain outstanding following the merger), some of which the combined company may in the future

TABLE OF CONTENTS

wish to repay or refinance on an opportunistic basis. However, disruptions in the credit markets or uncertainty in the United States or elsewhere, including as a result of the COVID-19 pandemic, could result in a tightening of financial markets. As a result of financial market turmoil, the combined company may not be able to obtain the necessary funding to refinance its existing debt obligations on favorable terms (or at all). If the combined company is unable to successfully refinance its obligations at reasonable terms and conditions (including, but not limited to, pricing and other fee payments), this could result in additional costs to the combined company.

Following the consummation of the merger, the combined company’s substantial leverage and debt service obligations could adversely affect its business.

Following the completion of the merger, the combined company will have a significant amount of indebtedness outstanding. On a pro forma basis, the consolidated indebtedness of the combined company would have been approximately $1.3 billion as of December 31, 2020 (see “Unaudited Pro Forma Condensed Combined Financial Statements,” including the notes thereto). The combined company’s future net consolidated borrowing costs, which cannot be predicted at this time, will depend on rates in effect from time to time, the structure of the indebtedness, taxes and other factors.

This substantial level of indebtedness could have important consequences to the combined company’s business, including, but not limited to:

•

limiting the combined company’s ability to borrow additional funds and increasing the cost of any borrowing;

•

increasing the combined company’s vulnerability to, and reducing its flexibility to respond to, general adverse economic and industry conditions;

•

limiting the combined company’s flexibility in planning for, or reacting to, changes in its business and the industry in which it operates;

•

placing the combined company at a competitive disadvantage as compared to its competitors, to the extent that they are not as highly leveraged; and

•

restricting the combined company from pursuing potential business opportunities.

The combined company’s future results will suffer if it does not effectively manage its expanded operations following the merger.

Following the merger, the size of the business of the combined company will be significantly larger than the current size of either Diamond S or INSW’s current businesses. The combined company’s future success depends, in part, upon its ability to manage this expanded business, which may pose substantial challenges for management, including challenges related to the management and monitoring of new operations and associated increased costs and complexity. There can be no assurance that the combined company will be successful or that it will realize the expected operating efficiencies, cost savings, revenue enhancements and other benefits currently anticipated from the mergers.

The combined company may be unable to make desirable acquisitions or to integrate successfully any businesses it acquires.

The future success of the combined company may depend in part on mergers or acquisitions or vessel acquisitions intended to complement, enhance or expand the combined company’s business or that might otherwise offer growth opportunities. The combined company’s ability to complete transactions in the future may be hindered by a number of factors, including potential difficulties in obtaining financing or in issuing the combined company’s own securities as payment in acquisitions or obtaining regulatory approvals.

Any future merger or acquisition that the combined company undertakes may pose risks related to the integration of the new business with the combined company’s business. The combined company may not achieve the benefits it expects from a particular merger, acquisition or investment, and furthermore, mergers, acquisitions or investments may also expose the combined company to various unanticipated liabilities. Mergers and acquisitions may also strain the combined company’s managerial and operational resources, as

TABLE OF CONTENTS

the challenge of managing new operations may divert its staff from monitoring and improving operations in its existing operations. If the combined company fails to coordinate its resources effectively to manage both its existing operations and any businesses the combined company acquires or with which it merges, this could have a material adverse effect on the combined company’s business, results of operations or financial condition.

The market price of shares of the combined company’s common stock may decline as a result of the merger, including as a result of some Diamond S and/or INSW stockholders adjusting their portfolios.

INSW expects that it will issue or reserve for issuance approximately 22,683,532 shares of INSW common stock in order to deliver the merger consideration to Diamond S shareholders at the effective time in connection with the merger and to assume Diamond S equity awards at the completion of the merger. The issuance of the shares of INSW common stock and the sale of additional shares that may become eligible for sale in the public market from time to time could have the effect of depressing the market value for shares of INSW common stock. The increase in the number of shares of INSW common stock may lead to sales of INSW common stock or the perception that sales may occur, either of which may adversely affect the market for, and the market value of, shares of INSW common stock.

In addition, the market price of shares of the combined company’s common stock may decline as a result of the merger if, among other things, the operational cost savings estimates in connection with the integration of Diamond S and INSW’s respective businesses are not realized or if the transaction costs related to the merger are greater than expected. The market price also may decline if the combined company does not achieve the perceived benefits of the merger as rapidly or to the extent anticipated by financial or industry analysts or if the effect of the transactions on the combined company’s financial position, results of operations or cash flows is not consistent with the expectations of financial or industry analysts.

If securities or industry analysts do not publish research or publish inaccurate or unfavorable research about the combined company’s business, the price and/or trading volume of shares of the combined company’s common stock could decline.

The trading market for shares of the combined company’s common stock will depend, in part, on the research and reports that securities or industry analysts publish about the combined company and its business. If too few analysts commence and maintain coverage of the combined company, the trading price for its shares might be adversely affected. Similarly, if one or more of the analysts currently covering Diamond S cease coverage of the combined company or fail to publish reports on it regularly, demand for shares of the combined company’s common stock could decrease, which might cause the price of shares of the combined company’s common stock and trading volume to decline. In addition, if analysts publish inaccurate or unfavorable research about the combined company’s business, the price and/or trading volume of shares of the combined company’s common stock could decline.

Future offerings of debt or equity securities by the combined company may materially adversely affect the share price, and future capitalization measures could lead to substantial dilution of existing stockholders’ interests in the combined company.

The combined company may seek to raise additional equity through the issuance of new shares or convertible or exchangeable bonds to finance future organic growth or acquisitions. Increasing the number of issued shares would dilute the ownership interests of existing stockholders. Stockholders’ ownership interests could also be diluted if other companies or equity interests in companies are acquired in exchange for new shares of the combined company’s common stock to be issued and if shares are issued to employees under future option plans.

INSW and Diamond S have different historical policies with respect to the payment of dividends and other distributions. The payment of future dividends and other distributions will depend on the combined company’s business, cash flows, financial condition and results of operations, and in the future stockholders may not receive dividends or other distributions regularly or at all.

INSW’s dividend distribution policy and Diamond S’ dividend policy have been different in the past. Diamond S has not paid dividends while INSW has paid a quarterly dividend. While the parties anticipate

TABLE OF CONTENTS

that, going forward, the board of directors of the combined company will declare and pay a quarterly dividend, there can be no guarantee that the combined company’s stockholders will receive or be entitled to dividends or other distributions commensurate with previous dividends or other distributions of INSW, and the amount of dividends or other distributions, if any, that are declared or paid to the combined company’s stockholders cannot yet be determined. Moreover, the INSW Board may also change its policy on the payment of dividends or other distributions at any time.

The decision whether to pay future dividends or make other distributions will be made by the combined company’s board of directors and will be dependent on the circumstances at the time and a number of other factors, including the combined company’s results of operations, financial and investment needs, the availability of distributable profits and reserves, the availability of sufficient funds or financing, the market price of shares of the combined company’s common stock, vessel divestitures, compliance with the combined company’s cash reserve policy, the combined company’s access to capital markets, as well as industry practice, the requirements of Marshall Islands law with respect to dividends or other distributions and other relevant factors. These factors may restrict the combined company’s ability to make dividends or other distributions and may cause the combined company to deviate from INSW’s currently existing dividend policies and guidance. The combined company may declare either no dividends or other distributions, or dividends or other distributions that are small relative to those paid or made by competitors. The combined company’s ability to pay dividends or make other distributions may also depend on whether profits from its operating subsidiaries are distributed to the combined company and whether this is possible may depend on the laws of the jurisdictions in which the subsidiaries are organized.

Should the combined company not pay regular dividends or make other distributions in the foreseeable future, former Diamond S shareholders who become stockholders of the combined company would have to rely on increases, if any, in the trading price of shares of the combined company’s common stock for any returns on their investment.

Each of Diamond S and INSW expects to incur substantial expenses related to the completion of the merger and the integration of Diamond S and INSW’s respective businesses.

Each of Diamond S and INSW will incur substantial expenses in connection with the completion of the merger (including payment of termination fees to CSMC) to integrate a large number of processes, policies, procedures, operations, technologies and systems of Diamond S and INSW in connection with the merger. The substantial majority of these costs will be non-recurring expenses related to the transactions and facilities and systems consolidation costs. The combined company may incur additional costs or suffer loss of business under third-party contracts that are terminated or that contain change in control or other provisions that may be triggered by the completion of the transactions, and/or losses of, or decreases in orders by, customers, and may also incur costs to retain certain key management personnel and employees. Diamond S and INSW will also incur transaction fees and costs related to formulating integration plans for the combined business, and the execution of these plans may lead to additional unanticipated costs and time delays. These incremental transaction-related costs may exceed the savings the combined company expects to achieve from the elimination of duplicative costs and the realization of other efficiencies related to the integration of the businesses, particularly in the near term and in the event there are material unanticipated costs. Factors beyond the parties’ control could affect the total amount or timing of these expenses, many of which, by their nature, are difficult to estimate accurately.

COMPARATIVE PER SHARE MARKET PRICE AND DIVIDEND INFORMATION

The following table sets forth the closing sale prices per share of INSW common stock and Diamond S common stock on the NYSE on March 30, 2021, the last trading day prior to the public announcement of the merger agreement, and on June 1, 2021, the last practicable trading day prior to the mailing of this joint proxy statement/prospectus. INSW common stock is traded on the NYSE under the symbol “INSW” and Diamond S common stock is traded on the NYSE under the symbol “DSSI.” The high and low trading prices for the INSW common stock on March 30, 2021, the last trading day immediately prior to the public announcement of the merger, were $18.77 and $17.90, respectively. The high and low trading prices for the Diamond S common stock on March 30, 2021, the last trading day immediately prior to the public announcement of the merger agreement, were $9.63 and $9.07, respectively. The table also shows the estimated implied value of the merger consideration proposed for each share of Diamond S common stock as of the same two dates. The implied value for share consideration was calculated by multiplying the closing sales price of a share of INSW common stock on the relevant date by the base exchange ratio of 0.55375 shares of INSW common stock for each share of Diamond S common stock.

	INSW Common Stock			Diamond S Common Stock			Implied Share Value of Share Consideration
March 30, 2021		$	18.36		$	9.60		$	10.17
June 1, 2021			20.28			10.67			11.23

The market prices of INSW common stock and Diamond S common stock have fluctuated since the date of the announcement of the merger agreement and will continue to fluctuate prior to the completion of the merger. For example, the value of INSW common stock may decrease following payment of the INSW special dividend or INSW FSO dividend, in each case if and when paid. No assurance can be given concerning the market prices of INSW common stock or Diamond S common stock before completion of the merger or of INSW common stock after the completion of the merger. Because the exchange ratio, which determines the merger consideration, will not be adjusted for changes in the market prices of either INSW common stock or Diamond S common stock, the market price of INSW common stock (and, therefore, the value of the merger consideration) when received by the Diamond S shareholders after the merger is completed could be greater than, less than or the same as shown in the table above. Accordingly, these comparisons may not provide meaningful information to stockholders in determining how to vote with respect to the proposals described in this joint proxy statement/prospectus. We urge you to obtain current market quotations for INSW common stock and Diamond S common stock and to review carefully the other information contained in this joint proxy statement/prospectus. Please see “Risk Factors — Risks Related to the Merger.” Because the market value of shares of INSW common stock that Diamond S shareholders will receive in the merger may fluctuate, Diamond S shareholders cannot be sure of the market value of the merger consideration that they will receive in the merger.”

TABLE OF CONTENTS

On February 23, 2021, the INSW’s Board declared a regular quarterly dividend of $0.06 per share of INSW common stock to record holders as of March 11, 2021. The terms of the merger agreement limit the ability of INSW to declare or pay additional dividends during the pendency of the merger without Diamond S consent, other than the INSW special dividend, INSW’s regular quarterly dividend of up to $0.06 per share of INSW common stock and the INSW FSO dividend. It is expected that INSW will declare and pay the INSW special dividend prior to the closing of the merger, with a record date on or after the date of the INSW special meeting.

Diamond S has not paid any cash dividends since its inception. The terms of the merger agreement limit the ability of Diamond S to declare or pay dividends prior to the completion of the merger. In addition, certain of Diamond S’ debt instruments place restrictions on its ability to pay cash dividends.

PARTIES TO THE MERGER

Information about International Seaways, Inc.

INSW and its wholly owned subsidiaries own and operate a fleet of oceangoing vessels engaged primarily in the transportation of crude oil and petroleum products in the International Flag trade. INSW’s vessel operations are organized into two segments: Crude Tankers and Product Carriers.

THE MERGER

Terms of the Merger

The Closing

At the effective time, Merger Sub will be merged with and into Diamond S, with Diamond S surviving the merger as a wholly-owned subsidiary of INSW. Immediately following the merger, it is expected that INSW will contribute Diamond S to International Seaways Operating Company, a direct wholly-owned subsidiary of INSW. As a result, among other things, INSW will become the ultimate parent of Diamond S and all of its subsidiaries.

The closing of the merger will take place on the third business day after satisfaction or, to the extent permitted by applicable law, waiver of the conditions to the consummation of the merger set forth in the merger agreement (except for conditions that by their nature are to be satisfied at the closing) subject to the satisfaction or, to the extent permitted by applicable, waiver of all the conditions to the consummation of the merger set forth in the merger agreement at the closing, unless another date or place is agreed to in writing by Diamond S and INSW.

The Merger Consideration

Subject to the terms and conditions set forth in the merger agreement, at the effective time, Diamond S shareholders will have the right to receive, with respect to each share of Diamond S common stock they hold at the effective time, 0.55375 validly issued, fully paid and non-assessable shares of INSW common stock, with cash paid in lieu of fractional shares of INSW common stock. The base exchange ratio will result in INSW stockholders owning approximately 55.75% of the outstanding shares of INSW common stock following the effective time of the merger and the pre-effective time Diamond S shareholders owning approximately 44.25% of the outstanding shares of INSW common stock following the effective time.

There is one instance in which the base exchange ratio would be altered. The base exchange ratio is subject to an upward adjustment to the extent that INSW sells any of its interest in or the assets of the FSO Joint Ventures prior to the effective time and pays a special dividend to INSW stockholders from the proceeds of any such sale (up to a maximum of $25 million). In that instance, the base exchange ratio will be increased in accordance with the terms of the merger agreement so as to cause Diamond S shareholders to hold up to an additional 0.67% of the outstanding shares of INSW common stock based on the amount of the dividend. For example, the full $25 million dividend from the proceeds of a sale of the FSO Joint Ventures would increase Diamond S shareholders’ pro forma ownership by 0.67% and a $12.5 million dividend will increase Diamond S shareholders’ pro forma ownership by 0.33%. If INSW sells any of its interest in or the assets of the FSO Joint Ventures prior to the effective time and pays a further special dividend to INSW stockholders from the proceeds of any such sale of $25 million prior to the effective time, INSW stockholders will own approximately 55.08% of the outstanding shares of INSW common stock following the effective time of the merger and the pre-effective time Diamond S shareholders will own approximately 44.92% of the outstanding shares of INSW common stock following the effective time.

The merger agreement does not contain any provision that would adjust the exchange ratio based on fluctuations in the market value of either company’s common stock. Because of this, the implied value of the stock consideration to Diamond S shareholders will fluctuate between now and the completion of the merger and will depend on the market value of INSW common stock at the time the merger is completed.

At the effective time, all shares of Diamond S common stock that are owned by INSW, Diamond S, Merger Sub or any of their respective direct or indirect wholly owned subsidiaries will be cancelled and will cease to exist and no consideration will be delivered in exchange for those shares.

Fractional shares will not be issued in accordance with the merger. Any Diamond S shareholders that would have received a fractional INSW share based on the exchange ratio above, will instead receive an amount in cash equal to the product of such fractional part, multiplied by the volume-weighted average trading price of INSW shares for the ten trading days preceding the date of the completion of the merger.

TABLE OF CONTENTS

Director and Officer Indemnification

Under the merger agreement, certain indemnification and insurance rights exist in favor of Diamond S’ current and former directors and officers. See “The Merger Agreement — Covenants and Agreements” and “The Merger Agreement — Indemnification; Exculpation and Insurance” for information about these rights.

Background of the Merger

The terms of the merger are the result of arm’s length negotiations between INSW and Diamond S. The following is a summary of the events leading up to the agreement to merge and the key meetings, negotiations, discussions and actions by and between INSW and Diamond S and their respective advisors that preceded the public announcement of the merger.

The management and boards of directors of INSW and Diamond S each regularly review its company’s respective results of operations and competitive positions in the industries in which it operates as well as the strategic options of its businesses in light of economic and regulatory conditions, among other things, including whether the continued execution of its strategies as a stand-alone company or the possible sale to, or a combination with, a third party offers the best avenue to enhance shareholder value. INSW and Diamond S, and their respective predecessors, have from time to time engaged in discussions about a potential strategic transaction involving the parties.

In October 2019, representatives of Jefferies engaged in informal discussions with Jeffrey Pribor, INSW’s Chief Financial Officer, regarding industry conditions and strategic options, including potential strategic transactions between Diamond S and INSW. Thereafter, in October 2019, and at the request of INSW management, representatives of Jefferies engaged in informal discussions with certain members of the Diamond S Board, regarding Diamond S’ interest in engaging in discussions regarding a potential transaction with INSW.

On November 4, 2019, the Diamond S Board was updated regarding such informal discussions regarding a potential strategic transaction between Diamond S and INSW.

Beginning in November 2019, Craig H. Stevenson, Jr., Diamond S’ President and Chief Executive Officer and member of the Diamond S Board, Kevin Kilcullen, Diamond S’ Chief Financial Officer, Lois Zabrocky, INSW’s President and Chief Executive Officer and member of the INSW’s board, and Mr. Pribor engaged in informal discussions regarding a potential strategic transaction between Diamond S and INSW. In late December 2019, Moelis reviewed certain financial information with Diamond S management to support them regarding these informal discussions.

In January 2020, Mr. Stevenson and Ms. Zabrocky agreed that there was sufficient interest from both companies to pursue exploring a potential strategic transaction between Diamond S and INSW and decided that the parties should enter into a confidentiality agreement, which Diamond S and INSW executed on February 4, 2020, to facilitate the sharing of information between the parties.

On February 25, 2020, Mr. Nadim Z. Qureshi, Diamond S’ Chairman of the Board, and Mr. Stevenson updated the Diamond S Board on the progress of discussions regarding a potential strategic transaction between Diamond S and INSW and Moelis’ proposed formal engagement as its financial advisor due to Moelis’ qualifications, industry experience and reputation.

On March 9, 2020, the INSW Board held a telephonic meeting at which INSW management updated the INSW Board on the progress of discussions regarding a potential strategic transaction between Diamond S and INSW.

On March 11, 2020, Diamond S confirmed its engagement of Moelis as its financial advisor since December 21, 2019 in connection with the potential strategic transaction between Diamond S and INSW and other strategic alternatives.

On June 10, 2020, the INSW Board held a telephonic meeting at which INSW management outlined key terms of a potential proposal to Diamond S, including relative ownership interests of the stockholders of the two companies, post-closing company governance and termination of the CSMC’s management of

TABLE OF CONTENTS

certain Diamond S vessels. The INSW Board determined to engage in exploratory discussions regarding a potential transaction on that basis.

On June 17, 2020, INSW delivered a preliminary, non-binding indicative proposal to Diamond S (the “June Proposal Letter”). The June Proposal Letter detailed INSW’s proposed terms for a potential strategic transaction with Diamond S, including INSW’s proposal that (i) such a transaction be structured as a stock-for-stock merger, (ii) a pro forma ownership split that would result in INSW stockholders owning 60% of the combined company and Diamond S shareholders owning the remaining 40% equity interest, with an exchange ratio of approximately 0.464 common shares of INSW for each common share of Diamond S held by Diamond S shareholders at the time of the merger, (iii) a post-closing board with two Diamond S designees and (iv) consummation of the merger to be conditioned on the termination of commercial and technical management services provided by CSMC on terms that are satisfactory to INSW. The June Proposal Letter also addressed certain governance matters, support and lockup agreements to be entered into concurrently with the execution of the definitive documentation and a proposal that the parties enter into a mutual exclusivity agreement to facilitate further discussions of the proposed merger.

On June 26, 2020, following receipt of the June Proposal Letter, the Diamond S Board held a meeting by video conference at which members of Diamond S management and representatives of Moelis were also present to provide an update as to the status of the preliminary discussions with INSW and their advisors and discuss the terms of the June Proposal Letter. In particular, the Diamond S Board discussed INSW’s proposed requirement that Diamond S terminate all commercial and technical management services provided by CSMC as a condition to the merger, procedurally how the Diamond S Board should consider further exploring a potential merger with INSW and the next steps. Each of the Diamond S directors disclosed to the Diamond S Board any interests and other material relationships that they may have in INSW or its affiliates.

On July 2, 2020, the Diamond S Board held a meeting by video conference at which members of Diamond S management and representatives of Moelis were also present to continue discussions regarding the status of the preliminary discussions with INSW and their advisors and the terms of the June Proposal Letter. Mr. Gerasimos G. Kalogiratos, a member of the Diamond S Board, offered to negotiate for and on behalf of CSMC if the Diamond S Board determined to negotiate an agreement for the early termination of the commercial and technical management services provided by CSMC. At the conclusion of the meeting, the Diamond S Board directed representatives of Moelis to discuss the material terms of the June Proposal Letter with representatives of Jefferies, including the proposed conditions to closing, the relative contributions of Diamond S and INSW, governance considerations and the management of the combined fleet.

In early July 2020, INSW management discussed with representatives of Jefferies the terms of the June Proposal Letter, and indicated to representatives of Jefferies that INSW may have flexibility on some material terms of the proposal, such as pro forma ownership splits for the companies’ respective shareholders and governance considerations, but that INSW would require that CSMC cease to provide commercial and technical management services as a condition to the proposed merger and that both parties negotiate exclusively with one another. Following this discussion, INSW management instructed representatives of Jefferies to convey such information regarding the June Proposal Letter to representatives of Moelis. Representatives of Jefferies subsequently discussed the terms of the June Proposal Letter and the information it had reviewed with INSW management with representatives of Moelis.

On July 17, 2020, the Diamond S Board held a meeting by video conference at which members of Diamond S management and representatives of White & Case LLP (“White & Case”) and Moelis were also present. White & Case had been serving as counsel to the Conflicts Committee of the Diamond S Board since its formation in March of 2020 and was present at the meeting in light of INSW’s requirement that there be a termination of CSMC’s commercial and technical management services as part of any merger. The Diamond S Board discussed the June Proposal Letter and the discussions between representatives of Moelis and Jefferies as to its terms. Upon further discussion, the Diamond S Board determined to further explore a potential merger with INSW. A representative of White & Case then provided an overview of the fiduciary duties of the Diamond S Board generally as well as in the context of exploring, evaluating, negotiating and approving a strategic transaction between Diamond S and INSW. White & Case and the Diamond S Board discussed the role of Mr. Kalogiratos and George Cambanis as Capital nominees to the Diamond S Board

TABLE OF CONTENTS

in light of INSW’s requirement that CSMC cease to provide commercial and technical management services as a condition to the proposed merger. The Diamond S Board discussed procedural matters in connection with a potential combination and requested that White & Case and Sullivan & Cromwell LLP (“S&C”), acting as counsel for CSMC, discuss the appropriate procedural approach to a potential combination and the role of Messrs. Kalogiratos and Cambanis in such decisions.

Following the July 17, 2020 meeting of the Diamond S Board, representatives of White & Case and S&C discussed the appropriate process for a potential merger between Diamond S and INSW as instructed. The Diamond S Board then held a meeting by video conference on July 20, 2020 at which members of Diamond S management and representatives of White & Case and Moelis were present. White & Case confirmed any interests the directors may have in the proposed merger. Following discussion of any such interests, the Diamond S Board resolved to form the Transaction Committee to be composed of Diamond S directors Messrs. Hal Malone and Nadim Qureshi, and Ms. Alexandra Kate Blankenship and to which the Diamond S Board delegated the power and authority to, among other things, propose, review and negotiate the terms of a possible transaction with INSW, including any alternative transaction and the terms and condition of the potential termination of the commercial relationships between Diamond S and CSMC, and to make recommendations to the Diamond S Board with respect to the possible transaction and such termination. The Transaction Committee formally engaged White & Case as legal counsel to Diamond S and the Transaction Committee and Moelis as its financial advisor in connection with the potential merger on July 21, 2020.

The Transaction Committee thereafter met regularly by video conference together with members of Diamond S management and representatives of White & Case and Moelis to discuss the status of negotiations, terms of the proposed merger and the termination of the commercial and technical management services provided by CSMC. On multiple occasions, the Transaction Committee directed representatives of Moelis to discuss certain terms of the proposed termination of the CSMC services with Mr. Kalogiratos, who represented CSMC in such negotiations. Representatives of Moelis and Mr. Kalogiratos discussed, in particular, various financial aspects relating to the remaining commercial and technical management services to be provided by CSMC to Diamond S pursuant to existing contractual arrangements and ways in which the parties could transition the management of vessels from CSMC to Diamond S upon the successful consummation of a potential merger with INSW. The Transaction Committee also directed representatives of Moelis to engage with representatives of Jefferies to plan logistics and key exchanges of information.

On August 4, 2020, the INSW Board held a telephonic meeting at which management updated the INSW Board on the status of a potential transaction with Diamond S, including that, although INSW had not received any formal response to the June Proposal Letter, a number of discussions had taken place between representatives of Moelis and Jefferies. Representatives of Jefferies also provided an update on its discussions to date with representatives of Moelis.

On August 17, 2020, Diamond S, CSMC and CMTC executed a mutual confidentiality and standstill agreement.

On September 29, 2020, the Transaction Committee sent a revised Term Sheet to CSMC reflecting the Transaction Committee’s positions on key issues.

On March 2, 2021, Mr. Qureshi called Mr. Wheat and representatives of Moelis called representatives of Jefferies to discuss the relative contributions of Diamond S and INSW and communicated that while the Transaction Committee was open to revisiting the parties’ pro forma ownership split in the combined company given the passage of time and based on the reduced value of the pre-closing dividend that INSW proposed to pay to its stockholders, the Transaction Committee’s position was that the appropriate relative ownership interests in the combined company following the merger would result in INSW stockholders owning 55.5% of the combined company and Diamond S shareholders owning the remaining 44.5% equity interest, which represented the midpoint between the previously agreed pro forma ownership split and INSW’s new proposal.

On March 2, 2021, Mr. Wheat called Mr. Qureshi and conveyed that the INSW Board was prepared to agree to a revised pro forma ownership split that would result in INSW stockholders owning 56.0% of the combined company and Diamond S shareholders owning the remaining 44.0% equity interest.

INSW management also discussed the status of discussions with CSMC and the status of due diligence on Diamond S.

TABLE OF CONTENTS

Recommendation of the INSW Board and its Reasons for the Transaction

At its meeting on March 30, 2021, the INSW board of directors unanimously (1) declared that the merger agreement and consummation of the transactions contemplated thereby, including the merger, are advisable and fair to, and in the best interests of INSW and its stockholders, (2) approved the merger agreement and the transactions contemplated thereby, including the merger, (3) authorized the execution, delivery and performance of the merger agreement, (4) declared that the INSW share issuance proposal be submitted for consideration at the INSW special meeting, (5) recommended in favor of the INSW share issuance and (6) approved the inclusion of the recommendation in this joint proxy statement/ prospectus.

In evaluating the merger agreement, the INSW board of directors consulted with and received the advice of INSW’s senior management and its legal and financial advisor, following an extensive due diligence process. In reaching its decision, the INSW board of directors considered a number of factors, including, but not limited to, the factors set forth below, which the INSW board of directors viewed as generally supporting its decision to approve the merger agreement and the transactions contemplated thereby and recommend that the INSW stockholders approve the INSW share issuance proposal (which are not necessarily listed in order of importance).

•

Scale and Fleet. The merger will enhance INSW’s capabilities in both the crude and product markets. With a fleet of 100 vessels, the combined company will be a diversified tanker company, with capability in each of VLCC, Suezmax, LR1/ Panamax and the MR markets. The merger will create the second largest U.S.-listed tanker company by vessel count and the third largest U.S.-listed tanker company by deadweight, with 100 vessels in the combined fleet. The combined company has enhanced ability to increase exposure to favorable markets such as the crude oil, refined petroleum and other products in the international shipping markets.

•

Synergies. INSW expects to realize estimated annual cost synergies in excess of $23 million and revenue synergies of $9 million, which are expected to be fully realizable during 2022. This includes cost synergies in each of cash salaries and benefits, office and administrative expenses, external management fees, professional fees and public company costs and non-cash compensation.

•

New Vessel Management. In connection with the transaction, Diamond S will terminate its vessel management arrangements with CSMC. This will give INSW greater control of Diamond S’ fleet following completion of the merger than Diamond S has had as an independent company.

•

Strong Financial Position. The combined company will have greater scale and financial resources. The transaction is expected to be accretive to INSW’s earnings and cash flow per share, even excluding potential revenue synergies and the increased size of the vessel fleet is expected to generate strong cash flows and can act as a reserve of saleable assets should INSW require cash in the future. Moreover, the combined company is expected to have a combined pro forma net leverage ratio of 42% as of December 31, 2020, which would be one of the lowest among peers in the tanker sector.

Other Factors Considered by the INSW Board. In addition to considering the strategic factors described above, the INSW Board considered the following additional factors, all of which it viewed as supporting its decision to approve the merger agreement:

•

the fact that no adjustment will be made in the merger consideration to be received by Diamond S’ shareholders in the merger as a result of possible increases or decreases in the trading price of shares of INSW common stock or shares of Diamond S common stock following the announcement of the merger;

•

INSW’s knowledge of Diamond S’ business, operations, financial condition, earnings and prospects, taking into account the results of INSW’s due diligence review of Diamond S and the fact that INSW and Diamond S operate in the same industry;

•

the current and prospective business climate in the shipping industry; the alternatives reasonably available to INSW, including remaining a standalone entity, the lack of other strategic alternatives, and the INSW Board’s belief that the merger with Diamond S would create the best reasonably available opportunity to maximize value for the INSW stockholders given the potential risks, rewards and uncertainties associated with each strategic alternative and without limiting strategic alternatives

TABLE OF CONTENTS

that INSW could pursue in the future, including other strategic transactions, joint ventures and vessel acquisitions and divestitures;

•

the projected financial results of INSW as a standalone company and the fit of the transaction with INSW’s previously established strategic goals;

•

the complementary cultures of INSW and Diamond S, including their long-term customer relationships and similar focus on safety and environmental, social and governance matters;

•

the recommendation of INSW’s senior management in favor of the merger;

•

the resulting percentage ownership interest that current INSW stockholders would have in the combined company following the merger;

•

the ability of INSW to continue to pay its regular quarterly dividends to its stockholders under the terms of the merger agreement during the pendency of the merger and INSW’s ability to make a special dividend of $31.5 million prior to the completion of the merger;

•

the fact that seven of the ten member board of the combined company will comprise members of the INSW Board as of immediately prior to the effective time, including the chairman;

•

the fact that senior management of the combined company will be comprised of senior management of INSW;

•

the fact that a group of shareholders, representing approximately 14% and 29% of the issued and outstanding shares of INSW and Diamond S, respectively, has committed to vote in favor of the merger, subject to the terms and conditions contained in voting and support agreements as more fully described in the sections entitled “The Merger Agreement — Cyrus Support Agreement”, “The Merger Agreement — Capital Support Agreement” and “The Merger Agreement — WL Ross Support Agreement”, and the resulting likelihood that the merger would be consummated;

•

the fact that INSW, as well as Diamond S, has agreed to use its reasonable best efforts to obtain the necessary approvals and clearances required under applicable antitrust laws to effect the merger, as more fully described in the section entitled “The Merger Agreement — Other Covenants and Agreements,” and the INSW’s board’s view, after consultation with its legal counsel, concerning the likelihood that regulatory approvals and clearances necessary to consummate the mergers would be obtained;

•

the fact that (1) Diamond S’ debt will remain outstanding following completion of the merger, (2) the terms of Diamond S’ debt will be amended to permit dividends and otherwise to more closely mirror the terms of INSW’s existing indebtedness, (3) there exists a large amount of overlap between Diamond S’ lenders and INSW’s lenders and (4) the fact that INSW’s debt will also remain outstanding following completion of the merger;

•

the expected tax-efficient treatment of the merger for U.S. federal income tax purposes, as more fully described below under the section entitled “Material U.S. Federal Income Tax Consequences of the Merger”;

•

the anticipated customer, supplier and stakeholder reaction to the merger;

•

the fact that the counterparties to both of Diamond S’ joint ventures consented to the merger prior to entering into the merger agreement, permitting the joint ventures to remain intact following completion of the merger;

•

the fact that Diamond S is obligated to pay INSW a termination fee of $17 million in certain circumstances;

•

the INSW Board’s right to withhold, withdraw or change its recommendation to the INSW stockholders to vote “FOR” the INSW share issuance proposal if a superior proposal is available has occurred or not to hold the INSW stockholder meeting, subject to INSW being obligated to pay Diamond S a termination fee of $19 million in the event INSW terminates the merger agreement prior to the INSW’s stockholders’ vote on the INSW share issuance proposal or in certain other

TABLE OF CONTENTS

circumstances in which INSW enters into definitive agreement with respect to a competing proposal within 12 months after the termination of the merger agreement, which competing proposal is subsequently consummated;

•

the ability of INSW’s stockholders to vote “FOR” or “AGAINST” the INSW share issuance proposal, with generally no termination fee being payable by INSW to Diamond S if the INSW stockholders do not approve the merger proposal and the INSW Board has not changed its recommendation to INSW stockholders to vote “FOR” the merger proposal, INSW has not breached certain provisions of the merger agreement and no competing proposal has been publicly made prior to the INSW special meeting;

•

the INSW Board’s conclusion, after consultation with INSW’s legal advisors, that the provisions of the merger agreement providing for the INSW Board’s ability to respond to alternative transaction proposals and change its recommendation to INSW stockholders to vote in favor of the adoption of the merger agreement are customary and reasonable for transactions of this type;

•

the outside date under the merger agreement, which is expected to allow for sufficient time to complete the merger;

•

the ability of Diamond S to seek specific performance of INSW’s obligations under the merger agreement; and

•

the financial analyses reviewed by Jefferies with the INSW Board as well as the opinion of Jefferies delivered to the INSW Board on March 30, 2021 as to the fairness, from a financial point of view, of the base exchange ratio provided for in the merger pursuant to the merger agreement. See “The Merger — Opinion of INSW’s Financial Advisor.”

Countervailing Factors. The INSW Board weighed these advantages and opportunities against a number of other risks and potential negative factors concerning the merger agreement and the merger, including:

•

the challenges inherent in the merger of two businesses of the size and scope of INSW and Diamond S, each of whose assets are scattered all of the world, and the size of the companies relative to each other, including the risk that integration costs may be greater than anticipated and the possible diversion of management attention for an extended period of time;

•

the difficulties of combining the businesses and workforces of INSW and Diamond S and the need to align Diamond S policies and internal controls to INSW policies and internal controls;

•

the substantial costs to be incurred in connection with the merger, including the costs of integrating the businesses of INSW and Diamond S, and the transaction expenses arising from the merger, including advisor fees;

•

Diamond S’ right, subject to certain conditions, to respond to and negotiate with respect to certain acquisition proposals from third parties made prior to the time the Diamond S shareholders approve the merger agreement and the right of the Diamond S Board to change its recommendation to the Diamond S shareholders to vote “FOR” the Diamond S merger agreement proposal in certain instances;

•

the restrictions in the merger agreement on the conduct of each of INSW’s and Diamond S’ respective business during the period between execution of the merger agreement and the consummation of the merger;

•

the risk of litigation, injunctions or other legal proceedings related to the transactions contemplated by the merger agreement;

•

the risk that the merger may not be completed despite the parties’ efforts, even if the requisite approvals are obtained from INSW stockholders and Diamond S shareholders, including the possibility that certain conditions to the merger may not be satisfied;

•

the risk that INSW stockholders or Diamond S shareholders may object to and challenge the merger and take actions that may prevent or delay the consummation of the merger, including to vote down the proposals at the INSW special meeting or Diamond S special meeting;

TABLE OF CONTENTS

•

the need to find a new technical manager for Diamond S vessels previously managed by CSMC and the possibility that transitioning the management of certain Diamond S vessels from CSMC to new management arrangements pursuant to the Capital Termination Agreement may present challenges or uncertainty and may not occur as seamlessly or as promptly as expected;

•

the risk that regulatory agencies may object to and challenge the merger or may impose terms and conditions in order to resolve those objections that adversely affect the financial results of INSW following the closing; see the section entitled “The Merger Agreement — Other Covenants and Agreements”;

•

the risk that the pendency of the merger for an extended period of time following the announcement of the execution of the merger agreement could have an adverse impact on INSW or Diamond S and that the merger could be pending for over seven months if the conditions to the merger relating to the receipt of the required regulatory approvals and clearances are not satisfied by November 1, 2021;

•

the potential for diversion of management and employee attention during the period prior to completion of the merger, and the potential negative effects on Diamond S’ and INSW’s respective businesses;

•

the risk of not capturing all the anticipated cost savings and revenue synergies between INSW and Diamond S and the risk that other anticipated benefits might not be realized;

•

the possibility that either INSW or Diamond S may not achieve its projected financial results;

•

the potential that the exchange ratio under the merger agreement could result in INSW delivering greater value to the Diamond S shareholders than had been anticipated by INSW should the value of the shares of INSW common stock increase disproportionately relative to the value of shares of Diamond S common stock from the date of the execution of the merger agreement;

•

the fact that the merger agreement prohibits each of INSW and Diamond S from soliciting or engaging in discussions regarding acquisition proposals during the pendency of the mergers, subject to limited exceptions;

•

the requirement that INSW pay Diamond S a $19 million termination fee if the merger agreement is terminated under certain circumstances, and the risks that such termination fee may discourage third parties that might otherwise have an interest in a business combination with, or acquisition of, INSW from making alternative proposals;

•

the possibility that the $17 million termination fee payable by Diamond S to INSW in specified circumstances may not fully compensate INSW for the harm it would suffer if the merger agreement is terminated and the merger does not occur;

•

the difficulty of transitioning management of Diamond S vessels from CSMC, particularly during the COVID-19 pandemic; and

•

the risks of the type and nature described under “Risk Factors” and the matters described under “Cautionary Statement Regarding Forward-Looking Statements.”

The foregoing discussion of the factors considered by the INSW Board is not intended to be exhaustive, but rather includes the principal factors considered by the INSW Board. In view of the wide variety of factors considered in connection with its evaluation of the merger and the complexity of these matters, the INSW Board did not find it useful and did not attempt to quantify or assign any relative or specific weights to the various factors that it considered in reaching its determination to approve the merger agreement and to make its recommendations to INSW stockholders. Rather, the INSW Board viewed its decisions as being based on the totality of the information presented to it and the factors it considered, including its discussions with, and questioning of, members of INSW’s management and INSW’s legal and financial advisors, as well as the directors’ individual experiences and expertise. In addition, individual members of the INSW Board may have assigned different weights to different factors.

In considering the recommendation of the INSW Board to approve the INSW share issuance proposal, INSW stockholders should be aware that INSW’s directors may have interests in the merger that are different

TABLE OF CONTENTS

from, or in addition to, those of INSW stockholders generally. For additional information, see the section entitled “The Merger — Interests of Certain of INSW’s Directors and Executive Officers in the Merger.”

The explanation of the reasoning of the INSW Board and certain information presented in this section are forward-looking in nature and, therefore, the information should be read in light of the factors discussed in the section entitled “Cautionary Statement Regarding Forward- Looking Statements.”

The INSW Board unanimously determined that the merger agreement and the transactions contemplated by the merger agreement, including the INSW share issuance, are advisable and fair to, and in the best interests of INSW and its stockholders and the INSW Board unanimously recommends that INSW stockholders “FOR” the INSW share issuance proposal and “FOR” the INSW adjournment proposal.

Consummation of the merger is conditioned on approval by the INSW stockholders of the INSW share issuance proposal, but is not conditioned on approval of the INSW adjournment proposal.

Opinion of INSW’s Financial Advisor

INSW retained Jefferies as its financial advisor in connection with a possible merger with Diamond S. In connection with this engagement, the INSW Board requested that Jefferies evaluate the fairness, from a financial point of view, of the base exchange ratio provided for in the merger pursuant to the merger agreement. At a meeting of the INSW Board held on March 30, 2021 to evaluate the merger, Jefferies rendered an oral opinion, confirmed by delivery of a written opinion dated March 30, 2021, to the INSW Board to the effect that, as of that date and based on and subject to various assumptions made, procedures followed, matters considered and limitations and qualifications on the review undertaken as described in its opinion, the base exchange ratio provided for in the merger pursuant to the merger agreement was fair, from a financial point of view, to INSW.

The full text of Jefferies’ opinion, which describes various assumptions made, procedures followed, matters considered and limitations and qualifications on the review undertaken by Jefferies, is attached as Annex B to this joint proxy statement/prospectus and is incorporated herein by reference. Jefferies’ opinion was provided for the use and benefit of the INSW Board (in its capacity as such) in its consideration of the merger and did not address the relative merits of the transactions contemplated by the merger agreement as compared to any alternative transaction or opportunity that might be available to INSW, nor did it address the underlying business decision by INSW to engage in the merger or the terms of the merger agreement (other than the base exchange ratio to the extent expressly specified therein) or the documents referred to therein. The base exchange ratio is subject to adjustment pursuant to the merger agreement, as to which adjustment Jefferies expressed no opinion. Jefferies’ opinion did not constitute a recommendation as to how any holder of shares of INSW common stock should vote on the merger or any matter related thereto. The following summary is qualified in its entirety by reference to the full text of Jefferies’ opinion.

In arriving at its opinion, Jefferies, among other things:

•

reviewed a draft dated March 30, 2021 of the merger agreement;

•

reviewed certain publicly available financial and other information about Diamond S and INSW;

•

reviewed certain information furnished to Jefferies by Diamond S’ management, including financial forecasts and analyses relating to the business, operations and prospects of Diamond S (the “Diamond S forecasts”);

•

reviewed certain information furnished to Jefferies by INSW’s management, including (a) an alternative version of the Diamond S forecasts incorporating certain adjustments thereto made and approved for Jefferies’ use by the senior management of INSW (the “adjusted Diamond S forecasts”), and (b) financial forecasts and analyses relating to the business, operations and prospects of INSW (the “INSW forecasts”);

•

held discussions with members of senior management of Diamond S concerning the matters described in the second and third bullet points above and with members of senior management of INSW concerning the matters described in the second through fourth bullet points above;

TABLE OF CONTENTS

•

reviewed certain third party appraisals and valuation estimates relating to certain assets of Diamond S and INSW, in each case as approved for Jefferies’ use by the senior management of INSW (collectively, the “appraisals and valuation estimates”);

•

reviewed the share trading price history and valuation multiples for the Diamond S common stock and the INSW common stock and compared them with those of certain publicly traded companies that Jefferies deemed relevant;

•

compared the proposed financial terms of the merger with the financial terms of certain other transactions that Jefferies deemed relevant; and

•

conducted such other financial studies, analyses and investigations as Jefferies deemed appropriate.

In its review and analyses and in rendering its opinion, Jefferies assumed and relied upon, but did not assume any responsibility to independently investigate or verify, the accuracy and completeness of all financial and other information that was supplied or otherwise made available by Diamond S or INSW or that was publicly available to Jefferies (including, without limitation, the appraisals and valuation estimates and the other information described above), or that was otherwise reviewed by Jefferies. With regard to the appraisals and valuation estimates, Jefferies assumed, with the consent of the INSW Board, that they provide an appropriate basis for evaluating Diamond S and INSW, as applicable, and Jefferies relied upon such appraisals and valuation estimates in its review and analyses and in rendering its opinion. Jefferies relied on assurances of the managements of Diamond S and INSW that they were not aware of any facts or circumstances that would make any of the foregoing information inaccurate or misleading. In its review, Jefferies did not obtain any independent evaluation or appraisal of any of the assets or liabilities (contingent, accrued, derivative, off-balance sheet or otherwise), nor did Jefferies conduct a physical inspection of any of the properties or facilities, of Diamond S or INSW, and Jefferies was not furnished with (in each case, other than the appraisals and valuation estimates), and assumed no responsibility to obtain, any such evaluations, appraisals or physical inspections. Jefferies did not evaluate the solvency or fair value of Diamond S, INSW or any other entity under any laws relating to bankruptcy, insolvency or similar matters.

With respect to the financial forecasts and estimates provided to and reviewed by Jefferies, Jefferies noted that projecting future results of any company is inherently subject to uncertainty. However, Jefferies was advised, and Jefferies assumed, that the Diamond S forecasts were reasonably prepared on bases reflecting the best currently available estimates and good faith judgments of the management of Diamond S as to the future financial performance of Diamond S and the other matters covered thereby, and the adjusted Diamond S forecasts and the INSW forecasts were reasonably prepared on bases reflecting the best currently available estimates and good faith judgments of the management of INSW as to the future financial performance of Diamond S and INSW, respectively, and the other matters covered thereby. With regard to the financial forecasts and estimates relating to Diamond S, at the direction of the INSW Board, Jefferies relied upon the adjusted Diamond S forecasts in its review and analyses and in rendering its opinion. Jefferies expressed no opinion as to such financial forecasts or estimates or the assumptions on which they were based.

Jefferies’ opinion was based on economic, monetary, regulatory, market and other conditions existing and which could be evaluated as of the date of Jefferies’ opinion. Jefferies expressly disclaimed any undertaking or obligation to advise any person of any change in any fact or matter affecting its opinion of which Jefferies became aware after the date of its opinion.

Jefferies made no independent investigation of, and Jefferies expressed no view or opinion as to, any legal, regulatory, accounting or tax matters affecting or relating to Diamond S, INSW or the merger, and Jefferies assumed the correctness in all respects material to its analyses and opinion of all legal, regulatory, accounting and tax advice given to INSW and/or the INSW Board, including, without limitation, with respect to changes in, or the impact of, accounting standards or tax and other laws, regulations and governmental and legislative policies affecting Diamond S, INSW or the merger and legal, regulatory, accounting and tax consequences to INSW of the terms of, and transactions contemplated by, the merger agreement and related documents. Jefferies was advised that the merger would qualify as a tax free reorganization for federal income tax purposes. Jefferies assumed that the merger would be consummated in accordance with the terms of the merger agreement without waiver, modification or amendment of any material term, condition

TABLE OF CONTENTS

or agreement and in compliance with all applicable laws, documents and other requirements and that the final form of the merger agreement would be substantially similar to the last draft reviewed by Jefferies. Jefferies also assumed that in the course of obtaining the necessary governmental, regulatory or third-party approvals, consents, waivers and releases for the merger or otherwise, including with respect to any divestitures or other requirements, no delay, limitation, restriction or condition would be imposed or occur that would have an adverse effect on Diamond S, INSW or the contemplated benefits of the merger or that otherwise would be material in any respect to Jefferies’ analyses or opinion.

Jefferies’ opinion did not address the relative merits of the transactions contemplated by the merger agreement as compared to any alternative transaction or opportunity that might be available to INSW, nor did it address the underlying business decision by INSW to engage in the merger or the terms of the merger agreement or the documents referred to therein, including the form or structure of the merger or any term, aspect or implication of any voting agreements, derivatives arrangements or other agreements, arrangements or understandings entered into in connection with, or contemplated by or resulting from, the merger or otherwise. Jefferies was not asked to address, and Jefferies’ opinion did not address, the fairness to, or any other consideration of, the holders of any class of securities, creditors or other constituencies of INSW or any other party. Jefferies expressed no view or opinion as to the prices at which the INSW common stock may trade or otherwise be transferrable at any time. Furthermore, Jefferies did not express any view or opinion as to the fairness, financial or otherwise, of the amount or nature of any compensation or other consideration payable to or to be received by any officers, directors or employees, or any class of such persons, in connection with the merger relative to the base exchange ratio or otherwise. The issuance of Jefferies’ opinion was authorized by the fairness committee of Jefferies.

In connection with rendering its opinion to the INSW Board, Jefferies performed certain financial and comparative analyses, including those described below. The following summary is not a complete description of all analyses performed and factors considered by Jefferies in connection with its opinion. The preparation of a financial opinion is a complex process involving subjective judgments and is not necessarily susceptible to partial analysis or summary description.

Jefferies believes that its analyses and the summary below must be considered as a whole and in context and that selecting portions of its analyses and factors or focusing on information presented in tabular format, without considering all analyses and factors or the narrative description of the analyses, could create a misleading or incomplete view of the processes underlying Jefferies’ analyses and opinion. Jefferies did not draw, in isolation, conclusions from or with regard to any one factor or method of analysis for purposes of its opinion, but rather arrived at its ultimate opinion based on the results of all analyses undertaken by it and assessed as a whole.

The estimates of the future performance of INSW and Diamond S in or underlying Jefferies’ analyses are not necessarily indicative of future results or values, which may be significantly more or less favorable than those estimates. In performing its analyses, Jefferies considered industry performance, general business and economic conditions and other matters, many of which are beyond the control of INSW and Diamond S. Estimates of the financial value of companies or businesses do not purport to be appraisals or necessarily reflect the prices at which companies, businesses or securities actually may be sold or acquired. Accordingly, the estimates used in, and the implied reference ranges resulting from, any particular analysis described below are inherently subject to substantial uncertainty and should not be taken as Jefferies’ view of the actual value of INSW or Diamond S or their respective businesses or securities.

The terms of the merger were determined through negotiations between the INSW Board and Diamond S, and the decision by the INSW Board to authorize the merger agreement was solely that of the INSW Board. Jefferies’ opinion and financial analyses were only one of many factors considered by the INSW Board and should not be viewed as determinative of the views of the INSW Board with respect to the merger or the base exchange ratio provided for in the merger.

Financial Analyses

The following is a summary of the material financial analyses reviewed with the INSW Board and performed by Jefferies in connection with its opinion. Considering the data below without considering the full narrative description of the financial analyses, including the methodologies and assumptions underlying the

TABLE OF CONTENTS

analyses, could create a misleading or incomplete view of Jefferies’ financial analyses. The order in which the financial analyses summarized below appear does not necessarily reflect the relative importance or weight given to such analyses.

Implied Value of Merger Consideration

Based on the closing price per share of INSW common stock of $18.26 as of March 29, 2021 and the approximately 28.5 million shares of INSW common stock that were outstanding of as March 8, 2021 on a fully diluted basis, Jefferies noted that the implied value of the INSW common stock as of March 29, 2021, after giving effect to the INSW special dividend in the amount of $31.5 million, was $17.15 per share (the “implied INSW ex-dividend value”).

Based upon the approximately 40.9 million shares of Diamond S common stock that were outstanding as of March 12, 2021 on a fully diluted basis, the implied INSW ex-dividend value of $17.15 per share, and the base exchange ratio of 0.55375, Jefferies noted that the implied value of the merger consideration pursuant to the merger agreement as of March 29, 2021 was approximately $9.50 per share of Diamond S common stock (the “implied merger consideration value”).

Net Asset Value Analysis

INSW

Jefferies performed a net asset value, or NAV, analysis for INSW on a standalone basis based on the fleet appraisals and estimates in the appraisals and valuation estimates for the vessels comprising INSW’s fleet. Jefferies estimated the NAV of INSW by taking the total of the vessel values of INSW’s fleet, based on the fleet appraisals and estimates in the appraisals and valuation estimates, which ranged from approximately $949.9 million to $1.057 billion, adding the value of INSW’s interest in certain joint ventures and its lightering business as provided by INSW management, subtracting the amount of INSW’s net debt, and adjusting for changes in working capital and certain other items (including net other assets, net capital expenditures adjustment, charter and purchase option agreements, and the pre-transaction INSW special dividend). This analysis resulted in a range of total NAVs for INSW of approximately $775.4 million to $882.5 million. Jefferies then divided the range of total NAVs of INSW by the number of fully diluted shares outstanding as of March 29, 2021 to derive a NAV per share value for INSW common stock. This analysis indicated a range of per share values of approximately $27.25 to $31.02 per share of INSW common stock, as compared to the implied INSW ex-dividend value of $17.15 per share.

Diamond S

Jefferies performed a net asset value, or NAV, analysis for Diamond S on a standalone basis based on the fleet appraisals and estimates in the appraisals and valuation estimates for the vessels comprising Diamond S’ fleet. Jefferies estimated the NAV of Diamond S by taking the total of the vessel values of Diamond S’ fleet based on the fleet appraisals and estimates in the appraisals and valuation estimates, which ranged from approximately $1.1692 billion to $1.409 billion, subtracting the amount of Diamond S’ net debt, and adjusting for the value of Diamond S’ interest in certain joint ventures, changes in working capital and certain other items (including net other assets pro forma for two asset sales completed in January 2021 and a CSMC termination fee of $34 million, net capital expenditures adjustments and charter and purchase option agreements). This analysis resulted in a range of total NAVs for Diamond S of approximately $566.8 million to $798.5 million. Jefferies then divided the range of total NAVs of Diamond S by the number of fully diluted shares outstanding as of March 29, 2021 to derive a NAV per share value for Diamond S common stock. This analysis indicated a range of per share values of approximately $13.84 to $19.50 per share of Diamond S common stock, as compared to the implied merger consideration value of $9.50 per share.

Implied Exchange Ratio Analysis

Jefferies calculated a range of implied exchange ratios, based on the net asset value analyses described above, by using the range of implied per share values for INSW of $27.25 to $31.02 and the range of implied per share values for Diamond S of $13.84 to $19.50. Jefferies calculated the range of implied exchange

TABLE OF CONTENTS

ratios by (i) dividing the low end of the range of per share values for Diamond S by the high end of the range of per share values for INSW, and (ii) dividing the high end of the range of per share values for Diamond S by the low end of the range of per share values for INSW. This analysis indicated a range of implied exchange ratios of 0.4463 to 0.7156, as compared to the base exchange ratio provided for in the merger of 0.55375.

Jefferies also calculated a range of implied exchange ratios by (a) dividing the low end of the range of per share values for Diamond S by the low end of the range of per share values for INSW, and (b) dividing the high end of the range of per share values for Diamond S by the high end of the range of per share values for INSW. This analysis indicated a range of implied exchange ratios of 0.5079 to 0.6288, as compared to the base exchange ratio provided for in the merger of 0.55375.

Selected Public Companies Analysis

Jefferies reviewed publicly available financial, stock market and operating information of INSW, Diamond S and selected publicly traded companies in the crude oil and products tanker sector of the seaborne transportation industry that Jefferies considered generally relevant for purposes of its analysis.

Jefferies reviewed, among other information and to the extent publicly available, the equity value per share of the selected public companies, calculated as fully diluted equity values based on closing stock prices on March 29, 2021, as a percentage of NAV. Financial data and NAVs of the selected public companies were based on estimated values from the Clarksons Shipping Intelligence Network database as of March 26, 2021, as adjusted for vessel age and profile, subtracting the amount of net debt and adjusting for changes in working capital based on public filings and other publicly available information, including, as applicable, charter adjustment value where rates and terms were disclosed and corresponding market rate estimates were available from the Clarksons Shipping Intelligence Network database as of March 26, 2021. Financial data of INSW was based on the INSW forecasts, financial data of Diamond S was based on the adjusted Diamond S forecasts, and the average fleet NAV for INSW and Diamond S, respectively, was based on the appraisals and valuation estimates.

The selected public companies and the financial data reviewed included the following:

Jefferies also calculated a range of implied exchange ratios by (a) dividing the low end of the range of per share values for Diamond S by the low end of the range of per share values for INSW, and (b) dividing the high end of the range of per share values for Diamond S by the high end of the range of per share values for INSW. This analysis indicated an implied exchange ratio of 0.5652, as compared to the base exchange ratio provided for in the merger of 0.55375.

Discounted Cash Flow Analysis

INSW

Jefferies performed a discounted cash flow analysis of INSW by calculating the estimated present value of the stand-alone unlevered, after-tax free cash flows (excluding FSO Income and Lightering Income) that INSW was forecasted to generate during the second half of the calendar year 2021 and the calendar years ending December 31, 2022 through December 31, 2025, and the present value of the terminal value of INSW, using the INSW forecasts provided by INSW management. The implied terminal value of INSW was derived by applying a selected range of terminal multiples of 7.0x to 8.0x to INSW’s estimated calendar year 2025 Adjusted EBITDA (excluding FSO Income and Lightering Income). The present values (as of June 30, 2021) of the cash flows and terminal values were then calculated using a selected discount rate range of 5.4% to 6.4%, which was based on INSW’s estimated weighted average cost of capital, to derive a range of implied enterprise values for INSW. Jefferies then subtracted from that range of implied enterprise values the amount of INSW’s total debt, added INSW’s cash and cash equivalents (including restricted cash and pro forma for the $31.5 million special dividend), and added the value of INSW’s interest in certain joint ventures and its lightering business, as provided by INSW management, and divided the result by the number of fully diluted shares of INSW common stock, each as provided or based upon information furnished to Jefferies by INSW management, to derive a range of implied equity values per share of INSW common stock. This analysis indicated a range of implied equity values per share of INSW common stock of approximately $33.63 to $39.38, as compared to the implied INSW ex-dividend value of $17.15 per share.

Diamond S

Jefferies performed a discounted cash flow analysis of Diamond S by calculating the estimated present value of the stand-alone unlevered, after-tax free cash flows that Diamond S was forecasted to generate during the second half of the calendar year 2021 and the calendar years ending December 31, 2022 through December 31, 2025, and the present value of the terminal value of Diamond S, using the adjusted Diamond S forecasts provided by INSW management. The implied terminal value of Diamond S was derived by applying a selected range of terminal multiples of 7.0x to 8.0x to Diamond S’ estimated calendar year 2025 Adjusted EBITDA. The present values (as of June 30, 2021) of the cash flows and terminal values were then calculated using a selected discount rate range of 5.7% to 6.7%, which was based on Diamond S’ estimated weighted average cost of capital, to derive a range of implied enterprise values for Diamond S. Jefferies then subtracted from that range of implied enterprise values the amount of Diamond S’ total debt, and added Diamond S’ cash and cash equivalents (pro forma for Diamond S’ two asset sales completed in January 2021), and divided the result by the number of fully diluted shares of Diamond S common stock, each as provided or based upon information furnished to Jefferies by INSW management, to derive a range of implied equity values per share of Diamond S common stock. This analysis indicated a range of implied equity values per share of Diamond S common stock of approximately $12.60 to $15.81, as compared to the implied merger consideration value of $9.50 per share.

Jefferies also performed a discounted cash flow analysis of Diamond S, taking into account the projected synergies from the merger as provided by INSW management, using the methodology described

TABLE OF CONTENTS

above. This analysis indicated a range of implied equity values per share of Diamond S common stock of approximately $17.26 to $21.07, as compared to the implied merger consideration value of $9.50 per share.

Implied Exchange Ratio Analysis

Jefferies calculated a range of implied exchange ratios, based on the discounted cash flow analyses described above, by using the range of implied per share values for INSW of $33.63 to $39.38 and the range of implied per share values for Diamond S of $12.60 to $15.81 (without taking into account the projected synergies) and $17.26 to $21.07 (taking into account the projected synergies from the merger as provided by INSW management). Jefferies calculated the range of implied exchange ratios by (i) dividing the low end of the range of per share values for Diamond S by the high end of the range of per share values for INSW, and (ii) dividing the high end of the range of per share values for Diamond S by the low end of the range of per share values for INSW. This analysis indicated a range of implied exchange ratios of 0.3199 to 0.4702 (without taking into account the projected synergies) and of 0.4383 to 0.6266 (taking into account the projected synergies from the merger as provided by INSW management), as compared to the base exchange ratio provided for in the merger of 0.55375.

Jefferies also calculated a range of implied exchange ratios by (a) dividing the low end of the range of per share values for Diamond S by the low end of the range of per share values for INSW, and (b) dividing the high end of the range of per share values for Diamond S by the high end of the range of per share values for INSW. This analysis indicated a range of implied exchange ratios of 0.3746 to 0.4016 (without taking into account the projected synergies), as compared to the base exchange ratio provided for in the merger of 0.55375.

Other Factors

Implied Historical Exchange Ratio Analysis

Jefferies also calculated, for reference purposes only, the implied historical exchange ratio for Diamond S common stock and INSW common stock, based on the daily closing price per share as of March 29, 2021 and for the various time periods set forth in the table below ending on that date. Jefferies calculated the implied historical exchange ratios by dividing the daily closing price per share of Diamond S common stock by the daily closing price per share of INSW common stock. This analysis indicated the following implied historical exchange ratios, compared, in each case, to the base exchange ratio provided for in the merger of 0.55375.

Implied Historical Exchange Ratio

			3 months						6 months						9 months						Since Diamond S Public Listing (March 2019)
Average Implied Exchange Ratio					0.4331						0.4263						0.4562						0.5308

Miscellaneous

INSW has agreed to pay Jefferies for its financial advisory services in connection with the merger an aggregate fee of $6.5 million, of which $2.0 million become payable upon delivery of Jefferies’ opinion to the INSW Board and the remainder of which is payable contingent upon the closing of the merger. INSW may also pay Jefferies an additional amount, to be determined in INSW’s sole discretion, of up to $1.0 million. In addition, INSW agreed to reimburse Jefferies for expenses, including fees and expenses of counsel, incurred in connection with Jefferies’ engagement and to indemnify Jefferies and related parties against liabilities, including liabilities under federal securities laws, arising out of or in connection with the services rendered and to be rendered by Jefferies under its engagement.

During the two years prior to the date of its opinion, Jefferies did not receive any fees from INSW or Diamond S for financial advisory or financing services. Jefferies may seek to, in the future, provide financial advisory and financing services to INSW, Diamond S or entities that are affiliated with INSW or Diamond S, for which Jefferies would expect to receive compensation. In addition, in the ordinary course of business, Jefferies and its affiliates may trade or hold securities or financial instruments (including loans

TABLE OF CONTENTS

and other obligations) of Diamond S, INSW and/or their respective affiliates for their own account and for the accounts of their customers and, accordingly, may at any time hold long or short positions or otherwise effect transactions in those securities.

Jefferies was selected as the financial advisor to INSW in connection with the merger because of its familiarity with INSW and because Jefferies is an internationally recognized investment banking firm with substantial experience in merger and acquisition transactions. Jefferies is regularly engaged in the valuation of businesses and their securities in connection with mergers and acquisitions, leveraged buyouts, negotiated underwritings, competitive bids, secondary distributions of listed and unlisted securities and private placements.

Recommendation of the Diamond S Board and its Reasons for the Transaction

In evaluating the merger agreement, the merger and the other transactions contemplated by the merger agreement, the Diamond S Board consulted with Diamond S’ management and legal and financial advisors and, in reaching its decision to approve the merger agreement and to recommend that Diamond S’ shareholders vote “FOR” the Diamond S merger proposal, the Diamond S Board considered a variety of factors, including the following (which are not necessarily in order of their relative importance):

•

The Diamond S’ Board’s knowledge of Diamond S’ business, operations, financial condition, earnings and prospects and of INSW’s business, operations, financial condition, earnings and prospects, taking into account the results of Diamond S’ due diligence review of INSW;

•

The fact that the merger will unite two companies with long-term customer relationships, similar cultures, and complementary positions in key tanker sectors;

•

The merger will enhance capabilities and scale in both the crude and product markets;

•

The merger will create the second largest U.S.-listed tanker company by vessel count and the third largest U.S.-listed tanker company by deadweight, with 100 vessels in the combined fleet;

•

The Diamond S Board’s expectation that the merger will present the combined company with the opportunity to realize estimated annual cost synergies in excess of $23 million and annual revenue synergies in excess of $9 million;

•

The Diamond S Board’s expectation that the merger will enable the combined company to maintain or enhance financial strength, including anticipated improvement in liquidity relative to applicable financial covenants, as INSW and Diamond S are expected to have a combined pro forma net leverage ratio that is one of the lowest in the tanker sector and across global shipping;

•

The enhanced ability of the combined company to increase exposure to favorable markets such as the crude oil, refined petroleum and other products in the international shipping markets;

•

The expectation that the merger will enable each of INSW and Diamond S to enhance fleet modernization;

•

The governance terms in the merger agreement, which provide, among other things, that upon the closing of the merger: the INSW Board will be comprised of (i) an initial chairman, designated by INSW, (ii) six additional directors, designated by INSW that are reasonably acceptable to Diamond S, (iii) three additional directors, designated by Diamond S that are reasonably acceptable to INSW and (iv) that each committee of the INSW Board following the closing will initially include one of the independent directors designated by Diamond S;

•

The fact that a group of shareholders, representing approximately 14% and 29% of the issued and outstanding shares of INSW and Diamond S, respectively, has committed to vote in favor of the merger, subject to the terms and conditions contained in voting and support agreements as more fully described in the sections entitled “The Merger Agreement — Cyrus Support Agreement”, “The Merger Agreement — Capital Support Agreement” and “The Merger Agreement — WL Ross Support Agreement”;

•

The opportunity that Diamond S shareholders will have to participate in the future performance of the combined company, including the revenue and cost synergies realized as a result of the combination,

TABLE OF CONTENTS

as holders of outstanding shares of Diamond S common stock as of immediately prior to the completion of the merger will hold, at a minimum, approximately 44.25% of the outstanding INSW common stock immediately after completion of the merger;

•

The fact that INSW, as well as Diamond S, has agreed to use its reasonable best efforts to obtain the necessary approvals and clearances required under applicable antitrust laws to effect the merger, as more fully described in the section entitled “The Merger Agreement — Other Covenants and Agreements,” coupled with the view of the Diamond S Board, after discussions with Diamond S’ legal advisors, that the merger is likely to be completed in a timely manner without the imposition by any relevant antitrust authority of any condition or requirement that would be sufficiently material to preclude the merger;

•

The base exchange ratio and merger consideration, including the Diamond S Board’s evaluation of the base exchange ratio relative to the value of common shares of Diamond S over various periods and relative to its current assessment of the synergies and other benefits of the merger;

•

The fact that the exchange ratio is fixed (subject to adjustment only upon the payment of an FSO Dividend) as further described in “The Merger Agreement — Merger Consideration”) and will not fluctuate in the event that the market price of INSW common stock increases relative to the market price of Diamond S common shares between the date of the merger agreement and the closing of the merger;

•

The financial analyses reviewed and discussed with the Diamond S Board on March 30, 2021 by representatives of Moelis in connection with the consideration by the Diamond S Board of the proposed merger provided for in the merger agreement, as well as the oral opinion, as of March 30, 2021, of Moelis rendered to the Diamond S Board on March 30, 2021 (which was subsequently confirmed in writing by delivery of Moelis’ written opinion addressed to the Diamond S Board dated the same date) as to, and subject to the assumptions made, procedures followed, matters considered and other limitations set forth in the opinion, the fairness, from a financial point of view, to the holders of Diamond S common stock, other than INSW and its affiliates, of the base exchange ratio in the merger pursuant to the merger agreement.

•

The right of the Diamond S Board, subject to certain conditions, to change its recommendation to its shareholders to vote “FOR” the merger proposal in response to a proposal to acquire Diamond S that is superior to the merger if the Diamond S Board determines that failure to take such action would be reasonably likely to constitute a breach of its fiduciary duties under applicable law;

•

The Diamond S Board’s conclusion, after consultation with Diamond S’ legal advisors, that the provisions of the merger agreement providing for the Diamond S Board’s ability to respond to alternative transaction proposals and change its recommendation to Diamond S shareholders to vote in favor of the authorization and approval of the merger agreement are customary and reasonable for transactions of this type;

•

The Diamond S Board’s consideration, from time to time, with the assistance of Diamond S’ management and legal counsel, of various potential strategic alternatives available to Diamond S, including remaining an independent company, and its conclusion that the merger presents a more favorable opportunity for Diamond S’ shareholders than the potential value that might result from remaining an independent company or pursuing other potential strategic alternatives;

•

The outside date under the merger agreement, which is expected to allow for sufficient time to complete the merger;

•

The ability of Diamond S to seek specific performance of INSW’s obligations under the merger agreement; and

•

The Diamond S Board’s belief that the terms of the ancillary agreements to be entered into upon consummation of the merger, including the Capital Termination Agreement, are reasonable.

In its deliberations regarding the merger, the Diamond S Board also weighed the opportunities and advantages described above against a number of uncertainties, risks and potential negative factors concerning the merger, including the following (which are not necessarily in order of their relative importance):

TABLE OF CONTENTS

•

The risk that the merger may not be completed despite the parties’ efforts, even if the requisite approvals are obtained from Diamond S’ and INSW’s respective shareholders, including the possibility that certain conditions to the merger may not be satisfied, including the delivery by certain of Diamond S’ existing lenders of A&R debt agreements, as more fully described in the section entitled “The Merger Agreement — Conditions to the Completion of the Merger”, which are outside the control of Diamond S;

•

The fact that the merger could be pending for over seven months if the conditions to the merger relating to the receipt of the required regulatory approvals and clearances are not satisfied by November 1, 2021 and the resulting potential for diversion of Diamond S’ management focus for such an extended period of time, coupled with the possible adverse effects of the pendency of the merger on Diamond S’ employees, customers, ship managers, providers, suppliers and regulatory and other business relationships, in particular if the merger is not completed;

•

The restrictions under the terms of the merger agreement on the conduct of Diamond S’ business prior to the completion of the merger, as more fully described in the section entitled “The Merger Agreement — Covenants and Agreements — Conduct of Business,” which could delay or prevent Diamond S from undertaking material strategic opportunities that might arise during the pendency of the completion of the merger, to the detriment of Diamond S’ shareholders, in particular if the merger is not completed;

•

The fact that the merger agreement includes customary restrictions on the ability of Diamond S to solicit offers for alternative proposals or to engage in discussions regarding such proposals, subject to exceptions, which could have the effect of discouraging such proposals from being made or pursued. The Diamond S Board understood that these provisions may have the effect of discouraging alternative proposals and may make it less likely that the transactions related to such proposals would be negotiated or pursued, even if potentially more favorable to the Diamond S shareholders than the merger;

•

The right of the INSW Board, subject to certain conditions, to change its recommendation to its shareholders to vote “FOR” the INSW share issuance proposal in response to a proposal to acquire INSW that is superior to the merger if the INSW Board determines that failure to take such action would be inconsistent with its fiduciary duties under applicable law;

•

The possibility that the $19 million termination fee payable by INSW to Diamond S in specified circumstances may not fully compensate Diamond S for the harm it would suffer if the merger agreement is terminated and the merger does not occur;

•

The possibility that Diamond S would be required to pay INSW a termination fee of $17 million under certain conditions, as more fully described in the section entitled “The Merger Agreement — Expenses and Termination Fees”;

•

The substantial costs to be incurred in connection with the merger, including the costs of integrating the businesses of INSW and Diamond S and the transaction expenses arising from the merger;

•

The possibility of not capturing all of the anticipated synergies and the risk that other anticipated benefits might not be realized;

•

The fact that the merger consideration is based on a fixed exchange ratio, which means that Diamond S shareholders could be adversely affected by a decrease in the trading price of INSW common stock during the pendency of the merger;

•

The possibility that Diamond S or INSW may be subject to lawsuits or other challenges to the merger, and adverse effects of these challenges, including any adverse rulings in lawsuits, may delay or prevent the merger from being completed or that may require Diamond S or INSW to incur significant costs to address such challenges, including any costs to defend or settle any lawsuits;

•

The difficulties and management challenges inherent in completing the merger, integrating the businesses and managing an expanded business, operations and workforce of the combined companies, particularly in light of the merger-of-equals nature of the transaction and the possibility that certain members of Diamond S’ senior management might not remain employed with the combined company;

TABLE OF CONTENTS

•

The possibility that transitioning the management of certain Diamond S vessels from CSMC to new management arrangements pursuant to the Capital Termination Agreement may present challenges or uncertainty and may not occur as seamlessly or as promptly as expected; and

•

The risks described in the section entitled “Risk Factors”.

In addition, the Diamond S Board was aware of and considered that Diamond S’ directors and executive officers may receive in connection with the merger certain benefits that are different from, and in addition to, those of Diamond S’ other shareholders (see the section entitled “The Merger — Interests of Diamond S’ Directors and Executive Officers in the Merger”).

The Diamond S Board considered the foregoing factors as a whole and unanimously concluded that the positive factors described above significantly outweighed the potential negative factors concerning the merger. In particular, the Diamond S Board concluded that the transaction provides a compelling opportunity to combine two of the leading tanker companies worldwide, with long-term customer relationships, similar cultures, and complementary positions in key tanker sectors. Accordingly, the Diamond S Board unanimously determined that entering into the merger agreement is in the best interests of Diamond S and its shareholders, and resolved to recommend to Diamond S shareholders that they vote to authorize and approve the merger agreement.

The foregoing discussion of the material factors considered by the Diamond S Board in its consideration of the merger is not intended to be exhaustive, but does set forth the principal factors considered by the Diamond S Board. In light of the number and wide variety of factors considered in connection with the evaluation of the merger, and the complexity of these matters, the Diamond S Board did not consider it practicable to, and did not attempt to, quantify, rank or otherwise assign relative weights or values to the specific factors it considered in reaching its final decision to approve the merger agreement. The Diamond S Board made its decision to approve the merger agreement based on all of the information available to it and the factors presented to and considered by it, including its experience and history. In addition, individual directors may themselves have given different weight to different factors.

The factors, potential risks and uncertainties contained in this explanation of Diamond S’ reasons for the transaction and other information presented in this section contain information that is forward-looking in nature and, therefore, should be read in light of the factors discussed in “Cautionary Statement Regarding Forward-Looking Statements.”

Opinion of Diamond S’ Financial Advisor

At the meeting of the Diamond S Board on March 30, 2021 to evaluate and approve the merger, Moelis delivered an oral opinion, which was confirmed by delivery of a written opinion, dated March 30, 2021, addressed to the Diamond S Board to the effect that, as of the date of the opinion and based upon and subject to the assumptions made, procedures followed, matters considered and other limitations set forth in the opinion, the base exchange ratio provided for in the merger pursuant to the merger agreement was fair, from a financial point of view, to the holders of Diamond S common stock, other than INSW and its affiliates.

The full text of Moelis’ written opinion dated March 30, 2021, which sets forth the assumptions made, procedures followed, matters considered and limitations on the review undertaken in connection with the opinion, is attached as Annex C to this joint proxy statement/prospectus and is incorporated herein by reference. Moelis’ opinion was provided for the use and benefit of the Diamond S Board (solely in its capacity as such) in its evaluation of the merger. Moelis’ opinion was limited solely to the fairness, from a financial point of view, to the holders of Diamond S common stock, other than INSW and its affiliates, of the base exchange ratio in the merger. Moelis’ opinion does not address Diamond S’ underlying business decision to effect the merger, or the relative merits of the merger as compared to any alternative business strategies or transactions that might be available with respect to Diamond S. Moelis’ opinion does not constitute a recommendation to any holder of securities as to how such holder should vote or act with respect to the merger or any other matter.

In arriving at its opinion, Moelis, among other things:

•

reviewed certain publicly available business and financial information relating to Diamond S and INSW;

TABLE OF CONTENTS

•

reviewed certain third-party vessel appraisals of Diamond S and INSW provided to Moelis by the management of Diamond S and certain adjustments to be made to such appraisals as agreed by Diamond S and INSW in connection with a net asset value analysis (referred to in this section as the “Appraisal Adjustments”);

•

reviewed certain internal information relating to the business, earnings, cash flow, assets, liabilities and prospects of Diamond S, including certain vessel sales, furnished to Moelis by Diamond S, including financial forecasts for Diamond S provided to or discussed with Moelis by the management of Diamond S (referred to in this section as the “Diamond S Projections”);

•

reviewed certain internal information relating to the business, earnings, cash flow, assets, liabilities and prospects of INSW furnished to Moelis by INSW, including financial forecasts for INSW provided to or discussed with Moelis by the management of INSW (referred to in this section as the “INSW Projections”);

•

reviewed estimates of management of INSW, as adjusted by the management of Diamond S, regarding cost savings and other synergies anticipated to result from the merger, including the amount and timing thereof (referred to in this section as the “Synergy Estimates”);

•

reviewed certain information relating to the capitalization of Diamond S and INSW furnished to Moelis by Diamond S and INSW, respectively;

•

considered certain potential pro forma impacts of the merger on the combined company resulting from the merger;

•

conducted discussions with members of the senior managements and representatives of Diamond S and INSW concerning the information described above, as well as the business and prospects of Diamond S and INSW, generally;

•

reviewed publicly available financial and stock market data of certain other companies in lines of business that Moelis deemed relevant;

•

reviewed a draft of the merger agreement made available to Moelis on March 30, 2021 and a draft, dated March 30, 2021, of the termination agreement by and between Diamond S and CSMC;

•

participated in certain discussions and negotiations among representatives of Diamond S and INSW and their advisors; and

•

conducted such other financial studies and analyses and took into account such other information as Moelis deemed appropriate.

In connection with its review, with Diamond S’ consent, Moelis relied on the information supplied to, discussed with or reviewed by it for purposes of its opinion being complete and accurate in all material respects. Moelis did not assume any responsibility for independent verification of, and Moelis did not independently verify, any of such information. With Diamond S’ consent, Moelis relied upon, without independent verification, the assessment of Diamond S with respect to legal, tax, regulatory and accounting matters and Moelis assumed that Diamond S had obtained advice as to such matters from appropriate professionals. With respect to the third-party vessel appraisals of Diamond S and INSW provided to Moelis by the management of Diamond S and the Appraisal Adjustments, Moelis assumed, at Diamond S’ direction, that they represented reasonable estimates regarding the matters covered thereby. With respect to the financial forecasts referred to above in this section, including Diamond S Projections and the INSW Projections, Moelis assumed, at Diamond S’ direction, that they had been reasonably prepared on a basis reflecting the best currently available estimates and judgments of the managements of Diamond S and INSW (as the case may be) as to the future performance of Diamond S and INSW, respectively. With respect to the Synergy Estimates, Moelis assumed, at Diamond S’ direction, that they have been reasonably prepared on a basis reflecting the best currently available estimates and judgments of the management of Diamond S as to the cost savings anticipated to result from the merger (including the amount and timing thereof). At Diamond S’ direction, Moelis assumed that the third-party vessel appraisals of Diamond S and INSW provided to Moelis by the management of Diamond S (and the Appraisal Adjustments) and the financial forecasts referred to above, including Diamond S Projections, the INSW Projections, and the Synergy Estimates, were a reasonable basis upon which to evaluate Diamond S, INSW and the merger and at Diamond

TABLE OF CONTENTS

S’ direction Moelis relied upon such appraisals (and the Appraisal Adjustments) and financial forecasts for purposes of its analyses and opinion. Moelis did not express any views as to the reasonableness of any appraisals, financial forecasts or other information or the assumptions or methodologies on which they were based. With Diamond S’ consent, Moelis did not make any independent evaluation or appraisal of any of the assets or liabilities (contingent, derivative, off-balance-sheet, or otherwise) of Diamond S or INSW, nor was it furnished with any such evaluation or appraisal (other than certain third-party vessel appraisals of Diamond S and INSW provided to Moelis by the management of Diamond S and the Appraisal Adjustments). With Diamond S’ consent, Moelis assumed that any adjustment to be made to the Exchange Ratio pursuant to the merger agreement, including the adjustment provided for in the merger agreement to account for a sale by INSW of certain specified interests or assets and the subsequent declaration and payment of a dividend to holders of INSW Common Stock of proceeds of such sale in an aggregate amount up to $25 million (referred to in this section as the “Sale Dividend”), would not be material to Moelis’ analyses or opinion.

Moelis’ opinion did not address Diamond S’ underlying business decision to effect the merger, or the relative merits of the merger as compared to any alternative business strategies or transactions that might be available to Diamond S and did not address any legal, regulatory, tax or accounting matters. Moelis was not asked to, and Moelis did not, offer any opinion as to any terms of the merger agreement or any aspect or implication of the merger, except for the fairness of the base exchange ratio in the merger pursuant to the merger agreement from a financial point of view to the holders of Diamond S common shares, other than INSW and its affiliates. In that regard, Moelis’ opinion did not address the fairness or reasonableness of the amount of the termination fee payable to CSMC to terminate the management agreements (“CSMC termination payment”), the INSW special dividend or the Sale Dividend. Moelis’ opinion also did not address the individual circumstances that may be applicable to any particular holder of Diamond S common shares, including any discount or premium that may be attributable to any such holder’s interest for any reason, or the non-economic rights of any such holder arising from its interest in the shares or otherwise. Moelis did not express any opinion as to what the value of INSW shares actually will be when issued in the merger or the prices at which Diamond S common shares or INSW shares may trade at any time. Moelis assumed, with Diamond S’ consent, that the INSW shares to be issued in the merger will be approved for trading on the New York Stock Exchange. Moelis assumed, with Diamond S’ consent, that the final executed form of the merger agreement and the CSMC termination agreement would not differ in any material respect from the drafts that it reviewed, that the merger (including the payment of the CSMC termination payment and the INSW special dividend) would be consummated in accordance with its terms without any waiver or modification that would be material to its analysis, and that the parties to the merger agreement would comply with all the material terms of the merger agreement. Moelis assumed, with Diamond S’ consent, that all governmental, regulatory or other consents or approvals necessary for the completion of the merger would be obtained, except to the extent that would not be material to Moelis’ analyses.

Moelis’ opinion was necessarily based on economic, monetary, market and other conditions as in effect on, and the information made available to Moelis as of, the date thereof, and Moelis assumed no responsibility to update its opinion for developments occurring or coming to its attention after such date.

Moelis’ opinion did not address the fairness of the merger or any aspect or implication thereof to, or any other consideration of or relating to, the holders of any class of securities, creditors or other constituencies of Diamond S, other than the fairness of the base exchange ratio in the merger pursuant to the merger agreement from a financial point of view to the holders of Diamond S common shares (other than INSW and its affiliates). Moelis did not express any opinion as to the fairness of the amount or nature of any compensation to be received by any officers, directors or employees of any parties to the merger, or any class of such persons, relative to the base exchange ratio or otherwise. Moelis’ opinion was approved by a Moelis fairness opinion committee.

This summary of the analyses is not a complete description of Moelis’ opinion or the analyses underlying, and factors considered in connection with, Moelis’ opinion. The preparation of a fairness opinion is a complex analytical process and is not necessarily susceptible to partial analysis or summary description. Selecting portions of the analyses or summary set forth above, without considering the analyses as a whole, could create an incomplete view of the processes underlying Moelis’ opinion. In arriving at its fairness determination, Moelis considered the results of all of its analyses and did not attribute any particular

TABLE OF CONTENTS

weight to any factor or analysis. Rather, Moelis made its fairness determination on the basis of its experience and professional judgment after considering the results of all of its analyses.

No company used in the analyses described below is identical to Diamond S or INSW. In addition, such analyses do not purport to be appraisals, nor do they necessarily reflect the prices at which businesses or securities actually may be sold. Analyses based upon forecasts of future results are not necessarily indicative of actual future results, which may be significantly more or less favorable than suggested by such analyses. Because the analyses described below (including much of the information used therein) are inherently subject to uncertainty, being based upon numerous factors or events beyond the control of the parties or their respective advisors, neither Diamond S nor Moelis or any other person assumes responsibility if future results are materially different from those forecasts.

The exchange ratio was determined through arms’ length negotiations between Diamond S and INSW and was approved by the board of directors of Diamond S. Moelis did not recommend any specific consideration to Diamond S or the Diamond S Board, or that any specific amount or type of consideration constituted the only appropriate consideration for Diamond S in the merger.

Summary of Financial Analyses

The following is a summary of the material financial analyses presented by Moelis in connection with its opinion to the board of directors of Diamond S at a meeting held on March 30, 2021. This summary describes the material analysis underlying Moelis’ opinion but does not purport to be a complete description of the analyses performed by Moelis in connection with its opinion.

In reviewing the base exchange ratio provided for in the merger, except where otherwise indicated, Moelis adjusted the ranges indicated by its analyses for Diamond S to account for the payment of the CSMC termination payment and for INSW to account for the payment of the INSW special dividend.

Some of the summaries of financial analyses below include information presented in tabular format. In order to fully understand Moelis’ analyses, the tables must be read together with the text of each summary. The tables alone do not constitute a complete description of the analyses. Considering the data described below without considering the full narrative description of the financial analyses, including the methodologies and assumptions underlying the analyses, could create a misleading or incomplete view of Moelis’ analyses.

For purposes of its analyses, Moelis reviewed a number of financial metrics, including the following, which are described below solely for purposes of this section, “The Merger — Opinion of Diamond S’ Financial Advisor”:

•

EBITDA — generally the amount of the relevant company’s earnings before interest, taxes, depreciation, and amortization for a specified time period.

•

Enterprise Value — generally the value as of a specified date of the relevant company’s outstanding equity securities (taking into account outstanding options and other securities convertible, exercisable or exchangeable into or for equity securities of the company) plus the value of its net debt (the face amount of total debt and preferred stock and the book value of non-controlling interests, less the amount of cash and cash equivalents, as reflected on then most recently available balance sheet).

Net Asset Value Analysis

Moelis performed an analysis of the net asset value (referred to in this section as “NAV”) of each of Diamond S and INSW, based on, as directed by Diamond S, certain third-party vessel appraisals of Diamond S and INSW provided to Moelis by the management of Diamond S and the Appraisal Adjustments.

Moelis calculated net asset values (referred to in this section as “Implied Adjusted NAVs”) using (i) total owned fleet value based on the third-party vessel appraisals, (ii) balance sheet information provided by Diamond S and INSW, including certain effects of asset sales, cash, indebtedness, net working capital, other assets and liabilities, and certain other items, (iii) estimates provided by Diamond S and INSW of values relating to (x) certain capital expenditure adjustments, (y) Diamond S’ and INSW’s respective time charters and (z) INSW’s purchase options in respect of certain vessels with bareboat charter-ins, (iv) values attributable to INSW’s FSO joint venture interests and Crude Tanker Lightering Business and (v) the

TABLE OF CONTENTS

amounts of the CSMC termination payment and the INSW special dividend. Moelis estimated a range of values for INSW’s interest in the INSW’s FSO joint venture by applying discount rates ranging from 7.50% to 11.00% to forecasts for the joint venture provided by INSW (and used by Moelis at Diamond S’ direction). Moelis estimated a range of values for INSW’s Lightering Business by applying a multiple range, informed by KNOT Offshore Partners LP 2021 estimated EBITDA trading multiple as of March 26, 2021, based on research analyst estimates, of 6.8x to 8.8x to INSW’s estimates of 2021 estimated EBITDA (adjusted by INSW to reflect a normalized run-rate EBITDA for 2021 excluding the effect of the COVID-19 pandemic) (and used by Moelis at Diamond S’ direction). The amounts used in these analyses, which were derived from the appraisals and other information provided by Diamond S and INSW, including the Appraisal Adjustments, as well as the resulting Implied Adjusted NAVs, were as follows:

	Diamond S						INSW
($ in millions)	Low			High			Low			High
Owned Fleet Value(1)		$	1,168.3		$	1,168.3		$	948.3		$	948.3

(1)

Third-party appraisals used by Moelis at direction of Diamond S. Vessel valuations and appraisals are commonly used in the shipping industry. The valuations and appraisals are estimates by their nature, and the amount realized upon the actual sale of a vessel could be more or less than the appraisal estimates. The fleet valuations were used to calculate NAVs for purposes of evaluating the implied exchange ratio.

As of December 31, 2020 and provided by Diamond S and INSW. Cash and Debt are pro forma for asset sales excluded from Fleet Value.

(3)

Reflect Appraisal Adjustments as agreed by Diamond S and INSW.

Estimate assuming closing of merger on June 30, 2021.

This analysis indicated an implied per share equity value for Diamond S, after giving effect to the CSMC termination payment, of approximately $15.51. This analysis indicated an implied per share equity value range for INSW, after giving effect to the INSW special dividend, of approximately $26.68 to $28.19.

Based on the implied per share equity value for Diamond S and the implied per share equity value range for INSW derived from the NAV analysis performed, the following implied exchange ratio range (representing the range determined by using (x) as the bottom end, the amount calculated by dividing the implied per share equity value for Diamond S by the upper bound of the implied per share equity value range for INSW and (y) as the top end, the amount calculated by dividing the implied per share equity value for Diamond S by the lower bound of the implied per share equity value range for INSW), as compared to the exchange ratio provided for in the merger, was indicated:

Implied Exchange Ratio Range:			Base Exchange Ratio
0.550x – 0.581x			0.55375x

TABLE OF CONTENTS

Discounted Cash Flow Analysis

Moelis performed discounted cash flow (“DCF”) analysis of each of Diamond S and INSW to calculate the present value of the estimated future unlevered free cash flows projected by Diamond S’ and INSW’s respective managements to be generated by Diamond S and INSW, respectively and the present value of estimated terminal values for Diamond S and INSW based on estimates of a terminal year Adjusted EBITDA projected by the management of Diamond S. The financial data for Diamond S and INSW was based on financial forecasts and other information and data provided by Diamond S and INSW, including Diamond S Projections and the INSW Projections. Estimates of terminal year Adjusted EBITDA for Diamond S and INSW were based on, as approved by Diamond S’ management, average annual Adjusted EBITDA projected for the years 2021 through 2025 to represent a mid-cycle normalized Adjusted EBITDA, adjusted, in the case of Diamond S, for the termination and elimination of certain management fees that expire in the first quarter of 2024 across the entire time period.

For Diamond S, Moelis utilized a range of discount rates (based on an estimated range of weighted average cost of capital for Diamond S) of 7.00% to 11.00% to calculate estimated present values as of December 31, 2020 of (i) estimated after-tax unlevered free cash flows for fiscal years January 1, 2021 through December 31, 2025 and (ii) estimated terminal values derived by applying a range of multiples of 4.00x to 5.00x to a terminal year Adjusted EBITDA, which multiple range was informed by both the historical and current EBITDA trading metrics for Diamond S.

For INSW, Moelis utilized a range of discount rates (based on an estimated range of weighted average cost of capital for INSW) of 6.50% to 10.75% to calculate estimated present values as of December 31, 2020 of (i) estimated after-tax unlevered free cash flows for fiscal years January 1, 2021 through December 31, 2025 and (ii) estimated terminal values derived by applying a range of multiples of 4.75x to 5.75x to a terminal year Adjusted EBITDA, which multiple range was informed by both the historical and current EBITDA trading metrics for INSW.

The ranges of weighted average cost referred to above reflected a derived cost of equity for each of Diamond S and INSW using (i) selected ranges of betas informed by selected publicly traded companies as of March 26, 2021, (ii) selected ranges of debt to total capitalization ratios informed by the selected publicly traded companies, and (iii) size premiums based on publicly traded companies with equity values similar to Diamond S and INSW.

This analysis indicated an implied per share equity value range for Diamond S, after giving effect to the CSMC termination payment, of approximately $4.47 to $9.76. This analysis indicated an implied equity value range for INSW, after giving effect to the INSW special dividend, of approximately $14.81 to $23.89.

Based on the implied per share equity value ranges for Diamond S and INSW derived from the discounted cash flow analysis performed, the following implied exchange ratio range (representing the range determined by using (x) as the bottom end, the amount calculated by dividing lower bound of the implied per share equity value range for Diamond S by the upper bound of the implied per share equity value range for INSW and (y) as the top end, the amount calculated by dividing upper bound of the implied per share equity value range for Diamond S by the lower bound of the implied per share equity value range for INSW), as compared to the exchange ratio provided for in the merger, were indicated:

Implied Exchange Ratio Range:			Base Exchange Ratio

Selected Publicly Traded Companies Analysis

Moelis performed a selected publicly traded companies analysis of each of Diamond S and INSW. Moelis reviewed financial and stock market information of the selected publicly traded companies that were categorized as crude fleet tanker companies, predominantly crude fleet tanker companies, mixed-fleet companies and product fleet tanker companies. Moelis selected companies that it deemed similar in one or more respects to Diamond S or INSW, including companies that owned and operated a fleet of oceangoing vessels engaged primarily in the transportation of crude oil and / or other petroleum products.

TABLE OF CONTENTS

Moelis reviewed, among other things, Enterprise Values of the selected publicly traded companies as a multiple of estimated EBITDA for 2022 and share price as a multiple of estimated net asset value per share. Enterprise Values used in the selected publicly traded companies analyses described below were calculated using the market price of the common stock of the selected publicly traded companies listed below as of March 26, 2021. Financial and certain other data (including EBITDA and NAV estimates) for the selected publicly traded companies, including Diamond S and INSW, were based on publicly available consensus research analysts’ estimates, public filings and other publicly available information. The selected publicly traded companies and their respective multiples are summarized below:

Moelis reviewed and determined not to take into account Frontline’s multiples due to Frontline’s historical trading premium to the peer group.

Moelis noted that in evaluating the appropriate multiple ranges to apply to Diamond S’ financial metrics, the low end of its selected multiple range was informed by the then current trading multiples of Diamond S’ shares, and the high end of its selected multiple range was informed by observed discounts in the historical trading multiples of Diamond S’ shares relative to the trading multiples of INSW’s shares. Moelis further noted that in evaluating the appropriate multiple ranges to apply to INSW’s financial metrics, the low end of its selected multiple range was informed by the then current trading multiples of INSW’s shares and the high end of its selected multiple range was informed by observed discounts in the historical trading multiples of INSW relative to the average trading multiples of the selected publicly traded companies (excluding Frontline Ltd.).

For Diamond S, Moelis applied ranges of selected multiples derived from the selected publicly traded companies of 4.50x to 5.50x to Diamond S’ 2022 estimated Adjusted EBITDA and 0.55x to 0.75x to Diamond S’ Implied Adjusted NAV referred to in the table above under the description of the NAV analysis. For INSW, Moelis applied ranges of selected multiples derived from the selected publicly traded companies of 5.25x to 6.25x to INSW’s 2022 estimated Adjusted EBITDA and 0.70x to 0.90x to the midpoint of the INSW’s Implied Adjusted NAV range referred to in the table above under the description of the NAV analysis. Financial data for Diamond S and INSW was based on Diamond S Projections and the INSW Projections and the other information and data provided by Diamond S’ management, including the third-party vessel appraisals of Diamond S and INSW provided to Moelis by the management of Diamond S and the Appraisal Adjustments.

This analysis indicated implied per share equity value ranges for Diamond S, after giving effect to the CSMC termination payment, of approximately $7.49 to $12.48 (based on the 2022 estimated Adjusted

EBITDA multiple) and $8.53 to $11.63 (based on the NAV multiple). This analysis indicated implied per share equity value ranges for INSW, after giving effect to the INSW special dividend, of approximately $26.85 to $34.20 (based on the 2022 estimated Adjusted EBITDA multiple) and $19.29 to $24.69 (based on the NAV multiple).

Based on the implied per share equity value ranges for Diamond S and INSW derived from the selected publicly traded companies analysis performed, the following implied exchange ratio ranges (representing the ranges determined by using (x) as the bottom end, the amount calculated by dividing lower bound of the implied per share equity value range for Diamond S by the upper bound of the implied per share equity value range for INSW and (y) as the top end, the amount calculated by dividing upper bound of the implied per share equity value range for Diamond S by the lower bound of the implied per share equity value range for INSW), as compared to the exchange ratio provided for in the merger, were indicated:

DCF Based Has — Gets Analysis

The DCF based has/gets analysis illustrated a comparison of the standalone implied per share equity value range for Diamond S indicated by its discounted cash flow analysis, before giving effect to the merger and the payment of the CSMC termination payment (the “Standalone Company DCF Share Value”), with the implied per share equity value range for the pro forma INSW adjusted by the exchange ratio and after giving effect to the consummation of the merger, including the Synergy Estimates, payment of the CSMC termination payment and the INSW special dividend and certain other pro forma effects of the merger reviewed with Diamond S (the “Pro Forma Company DCF Share Value”). The financial data for Diamond S and INSW was based on financial forecasts and other information and data provided by Diamond S and INSW, including the Diamond S Projections and the INSW Projections. For the pro forma discounted cash flow analysis, Moelis used a discount rate of 6.50% to 10.75% and a terminal multiple range of 4.50x to 5.75x.

Moelis noted that the range indicated by its discounted cash flow analysis for the Standalone Company DCF Share Value was $5.23 to $10.52 and the range indicated by its discounted cash flow analysis for the Pro Forma Company DCF Share Value was $8.13 to $14.59. Moelis then noted that the illustrative accretion relative (x) to the high end of the range for the Standalone Company DCF Share Value that is implied by the high end of the range for the Pro Forma Company DCF Share Value was 38.7% and (y) to the low end of the range for the Standalone Company DCF Share Value that is implied by the low end of the range for the Pro Forma Company DCF Share Value was 55.5%.

NAV Based Has — Gets Analyses

The NAV based has/gets analysis compared the estimated NAV per Diamond S share based on certain third-party vessel appraisals of Diamond S provided to Moelis by the management of Diamond S and the Appraisal Adjustments (the “Standalone Company NAV Share Value”), with an illustrative NAV per share of the pro forma INSW adjusted by the exchange ratio after giving effect to the consummation of the merger, including the Synergy Estimates, payment of the CSMC termination payment and the INSW special dividend and certain other pro forma effects of the merger reviewed with Diamond S (the “Pro Forma Company NAV Share Value”).

Moelis noted that the estimated Standalone Company NAV Share Value indicated by the NAV analysis was $16.27, and the range for the Pro Forma Company NAV Share Value indicated by the NAV analysis was $16.44 to $17.41. Moelis then noted that the illustrative accretion relative to the estimated Standalone Company NAV Share Value that is implied by (x) the high end of the range for the Pro Forma Company NAV Share Value was 7.0% and (y) the low end of the range for the Pro Forma Company NAV Share Value was 1.0%.

TABLE OF CONTENTS

Miscellaneous

Moelis acted as financial advisor to Diamond S in connection with the merger and will receive a transaction fee for its services, currently estimated to be approximately $8 million and calculated at closing in accordance with the terms of the Moelis’ engagement letter with Diamond S, contingent upon the consummation of the merger. Moelis also became entitled to receive a fee of approximately $2 million upon having substantially completed its work necessary to deliver its opinion, without regard to the conclusion reached therein, which is creditable against the transaction fee. In addition, Diamond S agreed to indemnify Moelis for certain liabilities and other items, including liabilities under the federal securities laws, arising out of its engagement. Moelis’ affiliates, employees, officers and partners may at any time own securities (long or short) of Diamond S and INSW. Moelis provided investment banking and other services to Diamond S unrelated to the merger and in the future may provide such services to Diamond S and INSW, and have received and may receive compensation for such services. In the past two years prior to the date of its opinion, Moelis (i) acted as financial advisor to Diamond S in connection with a business combination completed in March 2019, for which Moelis received $6 million in compensation and (ii) had not received any fees for financial advisory services from INSW. In the past two years prior to the date of its opinion, Moelis also provided investment banking and other services to certain of Diamond S’ significant shareholders, companies in which such shareholders had an interest and committees on which such shareholders participated, including acting as a financial advisor to WL Ross & Co in connection with a sale of an interest in a portfolio company that closed in December 2020, financial advisor to an ad hoc committee of senior secured creditors on which Invesco Ltd. or an affiliate thereof was a member in connection with a restructuring transaction that closed in October 2020, and financial advisor to a company in which Invesco Ltd. was a significant shareholder.

The board of directors of Diamond S selected Moelis as its financial advisor in connection with Diamond S merger because Moelis has substantial experience in similar transactions and familiarity with Diamond S. Moelis is regularly engaged in the valuation of businesses and their securities in connection with mergers and acquisitions, strategic transactions, corporate restructurings, and valuations for corporate and other purposes.

Certain Unaudited Forecasted Financial Information of INSW

Although INSW may issue limited financial guidance to investors periodically, INSW generally does not disclose projections of its expected future financial performance, revenues, earnings or other results due to, among other reasons, the inherent difficulty of accurately predicting financial performance for future periods and the uncertainty and subjectivity of the underlying assumptions and estimates. However, in connection with discussions between INSW and Diamond S regarding a business combination transaction, and the strategic review process conducted by the INSW Board that followed, INSW’s management prepared certain non-public unaudited financial projections and operating data for INSW as a stand-alone company, without giving effect to the merger, for the fiscal years ending December 31, 2021 through December 31, 2025, which were discussed with the INSW Board, and which are referred to as the “INSW forecasts.” The INSW forecasts were provided to Diamond S (except as indicated below) in connection with its consideration of the potential strategic transaction and to INSW’s financial advisor, Jefferies, in connection with its financial analyses. For more information, see the section entitled “The Merger — Opinion of INSW’s Financial Advisor.”

The financial forecasts provided in this section were not prepared for the purpose of public disclosure. However, a summary of the financial forecasts has been included in this section to provide INSW stockholders and Diamond S shareholders access to this financial information. The inclusion of the summary of the financial forecasts in this section should not be regarded as an indication that INSW, Diamond S, their respective financial advisors or any other recipient of this information considered, or now considers, it to be necessarily predictive of actual future results and it should not be relied upon as such.

public accounting firms, nor any other independent accountants, have compiled, examined or performed any procedures with respect to the financial forecasts summarized in this section, nor expressed any opinion or any other form of assurance with respect to this information or its achievability and assume no responsibility for, and disclaim any association with, the prospective financial information. The report of INSW’s independent registered public accounting firm contained in the INSW Annual Report on Form 10-K for the year ended December 31, 2020, which is incorporated by reference into this joint proxy statement/prospectus, relates to INSW’s historical financial statements. It does not extend to the financial forecasts in this section and should not be read to do so.

Although presented with numerical specificity, the financial forecasts in this section are subject in many respects and reflect the use of variables, estimates and assumptions that are inherently uncertain, susceptible to multiple interpretations and may be beyond the control of INSW, Diamond S or the combined company, and which may prove not to have been accurate at the time they were prepared or at any time during the period covered by the financial forecasts in this section. While in the view of INSW’s management, the financial forecasts in this section were prepared on a reasonable basis and reflect the best available estimates and judgments at the time of their preparation, the achievement of the results included in the financial forecasts in this section is subject to many risks and uncertainties. Important factors that may affect actual results and cause actual results to differ materially from the financial forecasts in this section include, but are not limited to, risks and uncertainties relating to INSW’s business (including its ability to achieve strategic goals and the effects that the merger may have on its business), industry performance, the laws to which INSW is subject, general business and economic conditions, market and financial conditions, tax rates, transactions or events that were not anticipated at the time the financial forecasts in this section were prepared, the COVID-19 pandemic, various risks set forth in INSW’s public filings with the SEC incorporated by reference herein and various risks and other factors described or referenced in the section entitled “Cautionary Statement Regarding Forward-Looking Statements” and in the section entitled “Risk Factors.”

The financial forecasts in this section do not necessarily reflect INSW’s current estimates and do not necessarily take into account any circumstance, transaction or event occurring after the date the financial forecasts in this section were prepared and some or all of the assumptions that had been made in the financial forecasts in this section and certain events and results after such date may have differed from the assumptions utilized in the financial forecasts in this section or might lead to different assumptions being utilized if forecasts were subsequently prepared. The financial forecasts in this section do not give effect to the merger or the potential synergies that may be achieved by the combined company as a result of the merger nor do they take into account the effect of any failure of the merger to occur. Actual results may have differed and may continue to differ, and may differ materially, from those contained in the financial forecasts in this section. For all the reasons discussed in this section, there can be no assurance that the financial forecasts in this section will be realized.

The financial forecasts in this section were prepared by INSW’s management, independent of, and without any collaboration or coordination with, Diamond S’ management, other than with respect to certain assumptions relating to day rates.

Neither INSW nor its affiliates, officers, directors or other representatives, gives any INSW stockholder or any other person any assurance that forecasted results will be realized or that financial results of INSW prepared after the date the financial forecasts in this section were prepared do not and will not differ materially from the financial forecasts in this section and, except as otherwise required by law, none of INSW, Diamond S or the combined company undertakes any obligation to update or otherwise revise or reconcile the financial forecasts in this section to reflect circumstances existing after the date the financial forecasts in this section were prepared, or to reflect the occurrence of future events, or to make any such update or other revision or reconciliation publicly available, even in the event that any or all of the assumptions and estimates underlying the financial forecasts in this section are shown to be in error.

TABLE OF CONTENTS

Diamond S, their respective financial advisors or any other recipient of this information considered, or now considers, the financial forecasts in this section to be material or to be a reliable prediction of actual future results. The financial forecasts in this section have not been included in an effort to influence any INSW stockholder’s or Diamond S shareholder’s decision to vote on any proposal. Rather, the summary of the INSW forecasts is included in this joint proxy statement/prospectus to give INSW stockholders and Diamond S shareholders access to non-public information that was provided to the INSW Board and the Diamond S Board in connection with their respective evaluations of the merger and the transactions contemplated thereby, and that was also provided to Diamond S’ financial advisor and INSW’s financial advisor in connection with each of their respective analyses and opinions.

The summary of the financial forecasts in this section covers multiple years and this information by its nature becomes subject to greater uncertainty with each successive year. The financial forecasts in this section should be evaluated, if at all, in conjunction with the historical financial statements and other information contained in this joint proxy statement/prospectus and INSW’s public filings with the SEC incorporated by reference herein.

The financial forecasts in this section reflect various assumptions and estimates that INSW’s management made in good faith for illustrative purposes at the time that the financial forecasts in this section were prepared, all of which are difficult to predict and many of which are beyond the control of INSW, Diamond S or the combined company.

INSW uses certain financial measures in the INSW forecasts that are not in accordance with GAAP as supplemental measures to evaluate operational performance. While INSW believes that non-GAAP financial measures provide useful supplemental information, there are limitations associated with the use of non-GAAP financial measures. Non-GAAP financial measures are not prepared in accordance with GAAP, are not reported by all of INSW’s competitors and may not be directly comparable to similarly titled measures of INSW’s competitors. Non-GAAP financial measures should not be considered in isolation from, or as a substitute for, financial information presented in accordance with GAAP. Financial measures included in forecasts (including the INSW forecasts) provided to a board of directors or financial advisor in connection with a business combination or asset acquisition transaction are excluded from the definition of “non-GAAP financial measures” under the rules of the SEC, and therefore the INSW forecasts are not subject to SEC rules regarding disclosures of non- GAAP financial measures, which would otherwise require a reconciliation of a non-GAAP financial measure to a GAAP financial measure. Reconciliations of non-GAAP financial measures were not provided to or relied upon by the INSW Board, Diamond S, or INSW’s or Diamond S’ respective financial advisors in connection with the merger. Accordingly, no reconciliation of the financial measures included in the INSW forecasts is provided in this joint proxy statement/prospectus.

In addition, Diamond S also reviewed certain non-public unaudited financial projections and operating data for INSW as a stand-alone company, without giving effect to the merger, for the fiscal years ending December 31, 2021 through December 31, 2025, provided by INSW, and made certain assumptions to develop additional estimates for INSW for purposes of evaluating the merger. Diamond S directed Moelis to use and rely on these forecasts and estimates for purposes of its financial analyses and opinion.

The INSW forecasts used by Diamond S and its financial advisor were based on and reflected the following:

Interests of Certain of INSW’s Directors and Executive Officers in the Merger

In considering the recommendations of the INSW Board that you vote to authorize and approve the INSW share issuance proposal, you should be aware that certain directors and executive officers of INSW have agreements or arrangements that provide them with interests in the merger that may be different from, or in addition to, the interests of the other stockholders of INSW. The INSW Board was aware of these interests when it approved the merger agreement and the transactions contemplated thereby and recommended that INSW stockholders vote “FOR” the INSW share issuance proposal.

As more fully described in “The Merger — Governance of the Combined Company after the Merger,” Doug Wheat, Lois Zabrocky and Jeffrey Pribor, Chairman of the INSW Board, Chief Executive Officer of INSW and Chief Financial Officer of INSW, respectively, will serve as the Chairman of the Board, Chief Executive Officer and Chief Financial Officer of the combined company, respectively, and, upon completion

TABLE OF CONTENTS

of the merger, the board of directors of the combined company will consist of ten directors, including seven INSW designees. Otherwise, none of the directors or executive officers of INSW has interests in the merger that may be different from, or in addition to, the interests of INSW’s stockholders generally. The members of the INSW Board were aware of these interests when it approved the merger agreement and transactions contemplated thereby and recommended that INSW stockholders approve the INSW share issuance proposal.

Interests of Diamond S’ Directors and Executive Officers in the Merger

In considering the recommendations of the Diamond S Board that you vote to authorize and approve the Diamond S merger proposal, you should be aware that certain directors and executive officers of Diamond S have agreements or arrangements that provide them with interests in the merger, including financial interests, that may be different from, or in addition to, the interests of the other shareholders of Diamond S. The Diamond S Board was aware of these interests when it approved the merger agreement and the transactions contemplated thereby and recommended that Diamond S shareholders vote “FOR” the Diamond S merger proposal. Such interests include the following and are more fully summarized below:

•

Diamond S’ executive officers have entered into individual agreements that provide for certain severance protections upon a qualifying termination;

•

Diamond S’ executive officers have entered into individual equity award agreements that provide for acceleration of vesting upon a qualifying termination;

•

Diamond S’ directors have entered into individual equity award agreements that provide for acceleration of vesting upon a change in control;

•

Diamond S’ executive officers may enter into new arrangements prior to or following the closing; and

•

Diamond S’ directors and executive officers are entitled to continued indemnification and insurance coverage under the merger agreement.

The Diamond S Board was aware of these interests during their deliberations of the merits of the merger and in determining to recommend that Diamond S shareholders vote in favor of the proposal to authorize and approve the merger agreement.

Continued Service of Certain Diamond S Directors and Executive Officers

Certain Diamond S’ directors are expected to continue as directors following consummation of the merger and Craig H. Stevenson, Jr. is expected to become a special advisor to the chief executive officer of the combined company.

Employment Agreements with Executive Officers

Diamond S’ executive officers are employed by its wholly-owned subsidiaries, Diamond S Management LLC, a limited liability company organized under the laws of the Republic of the Marshall Islands (“DSM”), and Diamond S Management (Singapore) Pte. Ltd, a company organized under the laws of Singapore (“DSMS”). DSM has an employment agreement with each of Craig H. Stevenson Jr., Kevin Kilcullen and Sanjay Sukhrani and DSMS has an employment agreement with Anoushka Kachelo. The merger will constitute a change in control for purposes of these employment agreements. Under these employment agreements the executive officers would become entitled to certain severance benefits if their employment with DSM or DSMS is terminated following consummation of the merger either by DSM or DSMS without “cause” or by the executive for “good reason” (as those terms are defined in their respective agreements). The potential severance benefits include a lump-sum cash severance payment equal to 24 months of base salary for Mr. Stevenson and Mr. Kilcullen and 12 months of base salary for Mr. Sukhrani and Mrs. Kachelo,

TABLE OF CONTENTS

a lump-sum cash amount equal to the executive’s target bonus for the year in which the termination occurs, and a lump-sum cash amount equal to the cost of premiums under COBRA for a period of 18 months for Mr. Stevenson and Mr. Kilcullen, and for a period of 12 months for Mr. Sukhrani following the termination date, all subject to a release of claims by the executive. These amounts would be payable on the sixtieth day following the applicable termination.

Acceleration of Equity Awards

If the Diamond S executive officers are terminated either by DSM or DSMS (as applicable) without “cause” or by the executive for “good reason” as those terms are defined in the executive’s respective restricted stock award agreements, restricted unit awards, and performance restricted stock unit agreements with Diamond S within two years after the merger, certain of the executive officers’ restricted stock awards and restricted unit awards would vest in full at the time of termination of employment and certain of the executive officers’ performance restricted stock units would vest with respect to a number of performance restricted stock units equal to the target number of performance restricted stock units awarded to the executive officer. The merger itself, absent a subsequent termination of employment, does not impact the treatment of the restricted stock awards, restricted unit awards and performance restricted stock awards held by the executive officers. Diamond S’ standard annual director awards provide for acceleration of vesting upon a change in control.

Agreements with the Surviving Corporation

Prior to or following the closing, certain executive officers of Diamond S may discuss or enter into agreements with the surviving corporation or any of its affiliates regarding employment with, or the right to purchase or participate in the equity of, the surviving corporation or one or more of its affiliates. Mr. Stevenson will serve as a special advisor to INSW’s chief executive officer for a six-month period following the completion of the merger for which he is expected to be paid $500,000. As of the date hereof, no other new employment or compensation arrangements between any executive officer of Diamond S and the surviving corporation for post-closing periods have been discussed, negotiated or established.

Indemnification and Insurance. From the completion of the merger through the sixth anniversary of the date on which the merger occurs, INSW has agreed to cause the surviving corporation, pursuant to the merger agreement, to maintain the existing directors’ and officers’ liability insurance policy maintained by Diamond S with respect to claims arising from facts or events occurring at or prior to the effective time (the “D&O insurance”). The surviving corporation will not be required to pay an annual premium for the D&O insurance that exceeds 400% of the last annual premium paid by Diamond S prior to the date of the merger agreement. If however the premium for the D&O insurance would at any time exceed 400% of the last annual premium paid by Diamond S, then the surviving corporation will maintain an insurance policy which, in its good faith determination, provides the maximum coverage available at an annual premium equal to the cap. Prior to the effective time, Diamond S may substitute a tail policy for Diamond S’ current directors’ and officers’ liability insurance policy providing equivalent coverage with a cost not exceeding 400% of the last annual premium paid prior to the date of the merger agreement by Diamond S for such policy. Diamond S will reasonably cooperate with INSW prior to the effective time to enable INSW, at INSW’s election, to purchase such a tail policy.

For a further discussion of the terms of the merger agreement with respect to indemnification in connection with the completion of the merger, please see the section captioned “The Merger Agreement — Indemnification; Exculpation and Insurance.”

Quantification of Payments to Diamond S Named Executive Officers in Connection with the Merger

In accordance with Item 402(t) of Regulation S-K, the table below sets forth the estimated amounts of compensation that are based on or otherwise relate to the merger and that may be payable to those individuals (comprising Diamond S’ existing named executive officers) who were listed in the “Summary Compensation Table” that was set out in Diamond S’ most recent securities filing for which disclosure was required under Item 402(c) of Regulation S-K (Form 10-K/A for the fiscal year ended December 31, 2020, filed with the SEC on April 30, 2021).

TABLE OF CONTENTS

See the section above entitled “The Merger — Interests of Diamond S’ Directors and Executive Officers in the Merger” for further information about the compensation disclosed in the table below. The amounts set out below assume (i) the merger was consummated on July 16, 2021, which is the assumed completion date of the merger solely for purposes of the disclosure in this section and (ii) the relevant price per share of Diamond S common stock is $10.73, which is the average closing price per share of Diamond S common stock as reported on the NYSE over the first five business days following the first public announcement of the merger on March 31. These amounts are estimates of amounts that might become payable to the named executive officers and the estimates are based on multiple assumptions that may or may not prove correct. Some of the assumptions are based on information not currently available and as a result the actual amounts received by a named executive officer may differ in material respects from the amounts set forth below.

As noted above under “The Merger — Interests of Diamond S’ Directors and Executive Officers in the Merger,” the consummation of the merger alone will not increase the pension/non-qualified deferred compensation amounts that were already otherwise earned by the executive officers.

Named Executive Officer	Cash (USD)(1)			Equity (USD)(2)			Pension/ Non-Qualified Deferred Compensation (USD)		Perquisites/ Benefits (USD)(3)			Tax Reimbursement (USD)		Other (USD)		Total (USD)
Craig H. Stevenson, Jr.		$	2,907,000		$	2,453,876		—		$	63,923		—		—		$	5,424,799

This column reflects the severance entitlements of our named executive officers pursuant to their respective employment agreements and represent the sum of (a) the value of (i) two (2x) times Mr. Stevenson’s and Mr. Kilcullen’s base salary, respectively, and (ii) one (1x) times Mr. Sukhrani’s base salary, plus (b) the value of the officer’s target annual cash bonus amount. These benefits are “double-trigger” in that there needs to be a “change in control” under the employment agreement (which will include the consummation of the merger) and Messrs. Stevenson, Kilcullen and Sukhrani would need to be terminated within two (2) years after a change in control without “cause” or resign for “good reason”. Details regarding the terms of these payments and the applicable release on which the payments are conditioned, are set forth in “The Merger — Interests of Diamond S’ Directors and Executive Officers in the Merger — Employment Agreements with Executive Officers.”

These components of the named executive officers’ severance are set forth in the following table:

Name	Cash Severance Payment (USD)			Target Annual Cash Bonus Award (USD)
Craig H. Stevenson, Jr.		$	1,938,000		$	969,000
Kevin Kilcullen			900,000			315,000
Sanjay Sukhrani			482,000			241,000

This column represents the value of unvested Diamond S restricted shares and Diamond S PSUs outstanding as of June 1, 2021, that would vest pursuant to the respective equity awards of the named executive officers. This benefit is “double-trigger” in that there needs to be a “change in control” under the equity award agreement (which will include the consummation of the merger), and Messrs. Stevenson, Kilcullen and Sukhrani would need to be terminated within two years after a change in control without “cause” or for “good reason”.

TABLE OF CONTENTS

Diamond S Restricted Shares

The table below provides information on the estimated value of unvested Diamond S restricted shares held by the named executive officers.

Treatment of Diamond S’ Equity Awards

Restricted Stock Units. As of the effective time of the merger, each outstanding Diamond S RSU awards under the Diamond S equity plan that is not then vested and does not vest at the effective time of the merger will be assumed by INSW and converted into INSW RSU awards with associated rights to the issuance of INSW common stock. Each assumed and converted INSW RSU awards will vest in full (at the target level, with respect to any Diamond S RSU awards subject to performance-based vesting criteria) on the holder’s termination of employment without “cause” or for “good reason” (as each such term is defined in the applicable award agreement) within twenty four (24) months following the closing date of the

TABLE OF CONTENTS

merger, and otherwise continue to have, and will be subject to, the same terms and conditions as applied to the applicable Diamond S RSU awards immediately prior to the effective time of the merger (but taking into account any changes thereto, including any necessary changes to any issuance provisions, provided for or permitted in the Diamond S equity plan, in any applicable award agreement or in such Diamond S RSU awards, by reason of the merger agreement or the consummation of the transactions contemplated thereby). To the extent any such Diamond S RSU awards are subject to performance vesting or other performance conditions, following the effective time of the merger, such awards will be deemed to have achieved at least the target level of performance. As of the effective time of the merger, the number of INSW common stock underlying each such INSW RSU award as so assumed and converted (rounded (x) up to the nearest whole share if half a share or more or (y) down to the nearest whole share if less than half a share) will equal the product of (i) the applicable number of shares of Diamond S common stock subject to such award, multiplied by (ii) the exchange ratio set forth in the merger agreement.

Restricted Stock. As of the effective time of the merger, INSW will assume and convert into INSW restricted shares each outstanding Diamond S restricted share granted under the Diamond S equity plan that is not then vested and does not vest at the effective time of the merger. Each assumed and converted INSW Restricted Share will continue to have, and will be subject to, the same terms and conditions as applied to the applicable Diamond S restricted shares immediately prior to the effective time of the merger (but taking into account any changes provided for in the Diamond S equity plan, in any applicable award agreement or in such Diamond S restricted shares, by reason of the merger agreement or the consummation of the transactions contemplated thereby). As of the completion of the merger, the number of INSW common stock underlying each such INSW restricted share as so assumed and converted (rounded (x) up to the nearest whole share if half a share or more or (y) down to the nearest whole share if less than half a share) will equal the product of (i) the applicable number of shares of Diamond S common stock subject to such award, multiplied by (ii) the exchange ratio set forth in the merger agreement. The table below sets forth the estimated value of unvested restricted stock and restricted stock units (time- and performance-based) as of June 1, 2021, the last practicable date prior to the date of this proxy statement, held by Diamond S’ named executive officers, based on the merger consideration. Depending on when the merger is completed, certain outstanding equity awards shown in the table below may become vested in accordance with their terms.

Named Executive Officer	Number of Restricted Stock (#)		Market value of unvested Restricted Stock (USD)(1)			Number of unvested RSUs (#)		Market value of unvested RSUs (USD)(1)		Number of unvested PSUs (#)		Market value of unvested PSUs (USD)(1)

The amounts reflected in these columns represent the number of stock awards reported in the immediately preceding column, multiplied by $10.73, which is the average closing price per share of Diamond S common stock as reported on the NYSE over the first five business days following the first public announcement of the merger on March 31, 2021.

Assumption of Diamond S Equity Plan and Equity Awards. At the effective time of the merger, INSW will assume all obligations of Diamond S under the Diamond S equity plan, each outstanding Diamond S equity award and the award agreements evidencing the grants, INSW will administer and honor all awards in accordance with the terms and conditions of such awards and the Diamond S equity plan pursuant to which they were granted (subject to the adjustments required by reason of the merger agreement or the consummation of the transactions contemplated thereby or such other adjustments or amendments made by INSW in accordance with such terms and conditions).

At the effective time of the merger, INSW will assume all rights and obligations in respect of the Diamond S equity plan. INSW will be able to grant stock awards under the terms of the Diamond S equity plan, to the extent permissible by applicable law, if INSW elects to assume the share reserves of the Diamond S equity plan as of the effective time of the merger, provided that: (i) stock covered by such awards will be INSW common stock; (ii) all references in the Diamond S equity plan to a number of Diamond

TABLE OF CONTENTS

S common stock will be amended or deemed amended to refer instead to a number of INSW common stock determined by multiplying the number of referenced Diamond S common stock by the exchange ratio set forth in the merger agreement, and rounding the resulting number down to the nearest whole number of INSW common stock; and (iii) the INSW Board or a committee thereof will succeed to the authority and responsibility of the Diamond S Board or any committee thereof with respect to the administration of the Diamond S equity plan.

Termination of Management Services Provided by CSMC

Messrs. Kalogiratos and Cambanis have been nominated to the Diamond S Board by the Capital shareholders, which are affiliated with CSMC. The Diamond S Board, understanding that the commercial and technical management services provided by CSMC would be required to be terminated in connection with the proposed merger, formed the Transaction Committee, to direct and oversee the negotiation of any transaction terms of the proposed merger and the related termination of such services.

Treatment of Indebtedness

It is expected that at the completion of the merger Diamond S will have approximately $625.6 million of indebtedness outstanding that INSW will maintain following completion of the merger plus an additional $30 million expected to be drawn down prior to the closing. The lenders under the applicable credit agreements related to such indebtedness have agreed to waive any event of default that would arise as a result of the merger and waive certain past events of default. For more information see “Indebtedness Amendments” below.

INSW existing debt will also remain outstanding following the completion of the merger.

Governance of the Combined Company after the Merger

Directors

The merger agreement provides that following the completion of the merger, the combined company will have a board of directors consisting initially of ten directors comprised of (i) a chairman, designated by INSW, who is expected to be Douglas D. Wheat, (ii) six additional directors, designated by INSW that are reasonably acceptable to Diamond S, one of whom is expected to be Lois K. Zabrocky and the remainder of whom are expected to be current INSW directors, and (iii) three additional directors, designated by Diamond S that are reasonably acceptable to INSW, one of whom is expected to be Craig H. Stevenson, Jr., and the remainder of whom are expected to be current Diamond S directors. In connection with the merger, the Capital shareholders (as defined below) and the WL Ross shareholders (as defined below) agreed to terminate their existing director designation agreements with Diamond S. As a result, no stockholder of the combined company will have a contractual right to designate a director to the board of directors of the combined company.

The merger agreement provides that the directors of Merger Sub immediately prior to the effective time will become the directors of Diamond S following the effective time.

Officers

The merger agreement provides that the officers of Merger Sub immediately prior to the effective time will become the officers of Diamond S following the effective time.

It is expected that the officers of INSW will remain in place following the effective time. Craig H. Stevenson, Jr., the current chief executive officer of Diamond S, will join the board of directors of the combined company and serve as a special advisor to INSW’s chief executive officer for a six-month period following the completion of the merger.

Listing of INSW Common Stock; Delisting and Deregistration of Diamond S Common Stock

It is a condition to the obligation of each of Diamond S and INSW to effect the merger that the shares of INSW common stock constituting the merger consideration are approved for listing on the NYSE, subject

TABLE OF CONTENTS

to official notice of issuance. Under the merger agreement, INSW is required to take all action necessary to cause the INSW shares issued as merger consideration to be approved on the NYSE prior to the effective time, subject to official notice of issuance, and Diamond S must cooperate with INSW in the preparation of the materials to be submitted to the NYSE and the resolution of any comments thereto received from the NYSE on such materials.

Such listing of shares of INSW common stock is subject to INSW fulfilling all of the listing requirements of the NYSE. For example, INSW will not be able to satisfy the listing requirements of the NYSE unless INSW obtains the INSW stockholder approval.

When the merger is completed, the Diamond S common stock listed on the NYSE under the symbol “DSSI” will cease to be quoted on the NYSE and will subsequently be deregistered under the Exchange Act. Diamond S expects to continue to comply with their duty to file reports under Section 13(a) or Section 15(d) of the Exchange Act, as applicable until the filing of a Form 25, expected to be 10 days after completion of the merger.

Accounting Treatment

INSW prepares its financial statements in accordance with GAAP. The merger is expected to be accounted for as an acquisition of Diamond S by INSW under the asset acquisition method of accounting in accordance with GAAP, which requires that one of the two companies in the merger be designated as the acquirer for accounting purposes based on the evidence available. INSW will be treated as the acquiring entity for accounting purposes. In identifying INSW as the acquiring entity for accounting purposes, the companies took into account the voting rights of all equity instruments, the planned composition of the corporate governing body and senior management, the size of each of the companies, and the terms of the exchange of equity interests. In assessing the size of each of the companies, the companies evaluated various metrics, including, but not limited to: assets, revenue, billings, operating income, operating cash flow and market capitalization. No single factor was the sole determinant in the overall conclusion that INSW is the acquirer for accounting purposes, rather all factors were considered in arriving at such conclusion. INSW stockholders will own a majority of the combined company following the closing. The planned composition of the senior management strongly implies INSW is the accounting acquirer, with all of executive management expected to come from INSW. The planned composition of the corporate governing body also suggests INSW is the accounting acquirer with seven directors of the combined company (including the chairman) coming from INSW and three directors coming from Diamond S. To a lesser extent, the continued use of the INSW corporate name, ticker symbol and corporate headquarters are all further indicators of INSW as the accounting acquirer.

Regulatory Matters

Under the HSR Act and related rules, certain transactions, including the merger, may not be completed until notifications have been given and information furnished to the Antitrust Division and the FTC and all statutory waiting period requirements have been satisfied. Completion of the merger is subject to the expiration or earlier termination of the applicable waiting period under the HSR Act. INSW and Diamond S each filed their respective HSR Act notification forms on April 21, 2021 and the waiting period under the HSR Act expired on May 21, 2021.

At any time before or after the expiration of the statutory waiting periods under the HSR Act, the Antitrust Division or the FTC may take action under the antitrust laws, including seeking to enjoin the completion of the merger, to rescind the merger or to conditionally permit completion of the merger subject to regulatory conditions or other remedies. In addition, non-U.S. regulatory bodies and U.S. state attorneys general could take action under other applicable regulatory laws as they deem necessary or desirable in the public interest, including, without limitation, seeking to enjoin or otherwise prevent the completion of the merger or permitting completion subject to regulatory conditions. Private parties may also seek to take legal action under regulatory laws under some circumstances. There can be no assurance that a challenge to the merger on antitrust or other regulatory grounds will not be made or, if such a challenge is made, that it would not be successful.

TABLE OF CONTENTS

Timing of the Transaction

The merger is expected to be completed in the third quarter of 2021 after the Diamond S special meeting and the INSW special meeting (assuming the Diamond S shareholder approval and the INSW stockholder approval are obtained at the respective special meetings). It is also possible that the regulatory approvals described above may only be obtained after the special meetings and that such approvals will determine the timing of the completion of the merger. Neither Diamond S nor INSW can predict, however, the actual date on which the merger will be completed because it is subject to conditions beyond each company’s control, including obtaining necessary regulatory approvals. See “The Merger Agreement — Conditions to the Completion of the Merger” and “The Merger — No Dissenters or Appraisal Rights.”

Appraisal rights are not available in all circumstances, and exceptions to these rights are provided under the BCA. Section 100 of the BCA provides that stockholders have the right, in some circumstances, to dissent from certain corporate actions and to instead demand payment of the fair value of their shares. Stockholders do not have the right to receive payment of the fair value of their shares for the shares of any class or series of stock, which shares or depository receipts in respect thereof, at the record date fixed to determine the stockholders entitled to receive notice of and to vote at the meeting of stockholders to act upon the agreement of merger or consolidation or any sale or exchange of all or substantially all of the property and assets of the corporation not made in the usual course of its business, were either (i) listed on a securities exchange or admitted for trading on an interdealer quotation system or (ii) held of record by more than 2,000 holders.

Because Diamond S common stock is listed on the NYSE, a national securities exchange, Diamond S shareholders will not be entitled to appraisal rights in connection with the merger. Because INSW is not a constituent company in the merger, its stockholders will not be entitled to appraisal rights in connection with the merger.

Litigation Related to the Merger

As of the date of this proxy statement, neither INSW nor Diamond S is subject to any filed stockholder litigation related to the merger.

Accordingly, the representations and warranties in the merger agreement should not be relied on by any persons as characterizations of the actual state of facts about INSW or Diamond S at the time they were made or otherwise.

Structure of the Merger

The merger agreement provides that, upon the terms and subject to the conditions set forth in the merger agreement, and in accordance with the BCA, Merger Sub will be merged with and into Diamond S at the completion of the merger. As a result of the merger, the separate corporate existence of Merger Sub will cease and Diamond S will continue as the surviving corporation as a wholly owned subsidiary of INSW.

At the completion of the merger, the certificate of incorporation of Diamond S and the by-laws of Diamond S will be amended and restated in their entirety to be (1) in the form of the certificate of incorporation attached to the merger agreement as Exhibit A, a copy of which is attached to this joint proxy statement/prospectus as Annex A, and (2) the by-laws of Merger Sub as in effect immediately prior to the completion of the merger (except that the name of the surviving corporation will be “Diamond S Shipping Inc.”).

The directors and officers of Merger Sub immediately prior to the effective time will become the directors and officers of the surviving corporation.

Merger Consideration

At the completion of the merger, upon the terms and subject to the conditions set forth in the merger agreement, each issued and outstanding share of Diamond S common stock (other than the excluded shares) will be automatically converted into the right to receive the merger consideration, which is:

•

0.55375 validly issued, fully paid and non-assessable shares of INSW common stock; plus

TABLE OF CONTENTS

•

if applicable, cash in lieu of fractional shares of INSW common stock at a price determined based on the volume-weighted average trading price of shares of INSW common stock in the ten trading days prior to the date of the completion of the merger, referred to as the fractional share consideration.

The 0.55375 shares of INSW common stock into which each share of Diamond S common stock (other than the excluded shares) will be converted is referred to as the base exchange ratio.

The base exchange ratio may be adjusted should an exchange ratio adjustment event occur prior to the completion of the merger. An exchange ratio adjustment event occurs if INSW consummates a sale of its interest in the FSO Joint Ventures, coupled with the declaration and payment by INSW of a dividend from the proceeds of such sale, up to $25 million. Should such an event occur prior to the completion of the merger, the base exchange ratio will be increased to a ratio necessary to cause the number of fully paid INSW shares issuable to Diamond S shareholders to equal (a) the implied pro forma ownership of former Diamond S shareholders in the Combined Company (estimated to be 44.25%) plus (b) 0.0067 multiplied by a fraction, the numerator of which is the amount of the INSW FSO dividend and the denominator of which is $25 million. We refer to the base exchange ratio as so adjusted as the exchange ratio or merger consideration. The merger consideration will be adjusted appropriately to reflect the effect of any stock split, reverse stock split, stock dividend, reorganization, recapitalization, reclassification, combination, exchange of shares or other changes with respect to the Diamond S common stock or INSW common stock.

Prior to the completion of the merger, the bank or trust company designated by INSW (and accepted by Diamond S) as the exchange agent will enter into an agreement with INSW, setting forth the exchange agent’s duties, responsibilities and obligations. The exchange agent will act as the agent for Diamond S’ shareholders for receiving and holding their certificates and shares from INSW. At or prior to the completion of the merger, INSW will deposit with the exchange agent an exchange fund consisting of (i) evidence of INSW common stock issuable in a book-entry form equal to the aggregate merger consideration and (ii) cash in immediately available funds in an amount sufficient to pay the aggregate fractional share consideration and any dividends that might be payable until the surrender of each Diamond S stock certificate. If the exchange fund is insufficient to pay the aggregate fractional share consideration and any applicable dividends, INSW will promptly deposit additional funds with the exchange agent.

Fractional Shares

No fractional shares of INSW common stock will be issued upon the surrender for exchange of certificates or book-entry shares, and such fractional share interests will not entitle the owner thereof to any shares of INSW common stock or to vote or to any other rights of a INSW stockholder. Each holder of shares of Diamond S common stock converted pursuant to the merger who would otherwise have been entitled to receive a fraction of a share of INSW common stock will receive, in lieu thereof, cash (without interest) in an amount equal to the product of (1) the fractional part of a share of INSW common stock and (2) the volume weighted average trading price of shares of INSW common stock for a ten day trading period, starting with the opening of trading on the 11th trading day prior to the date of the completion of the merger to the closing of trading on the second to last trading day prior to the date of the completion of the merger, as reported by Bloomberg L.P. or, if not reported therein, by another authoritative source mutually selected by INSW and Diamond S.

Treatment of Diamond S’ Equity Awards

As of the effective time of the merger, each outstanding restricted stock unit (the “Diamond S RSUs”) under the Diamond S Shipping Inc. 2019 Equity and Incentive Plan, amended as of March 27, 2019 (the “Diamond S Equity Plan”) that is not then vested and does not vest at the effective time of the merger will be assumed by INSW and converted into a restricted stock unit award for capital stock of INSW (the “INSW RSUs”) with associated rights to the issuance of additional capital stock of INSW common stock. Each assumed and converted INSW RSU will vest in full (at the target level, with respect to any Diamond S RSUs subject to performance-based vesting criteria) on the holder’s termination of employment without “cause” or for “good reason” (as each such term is defined in the applicable award agreement) within twenty four (24) months following the closing date of the merger, and otherwise continue to have, and will be subject to, the same terms and conditions as applied to the applicable Diamond S RSUs

TABLE OF CONTENTS

immediately prior to the effective time of the merger (but taking into account any changes thereto, including any necessary changes to any issuance provisions, provided for or permitted in the Diamond S Equity Plan, in any applicable award agreement or in such Diamond S RSUs, by reason of the merger agreement or the consummation of the transactions contemplated thereby). To the extent any such Diamond S RSUs are subject to performance vesting or other performance conditions, following the effective time of the merger, such awards will be deemed to have achieved at least the target level of performance. As of the effective time of the merger, the number of shares of INSW common stock underlying each such INSW RSU as so assumed and converted (rounded (x) up to the nearest whole share if half a share or more or (y) down to the nearest whole share if less than half a share) will equal the product of (i) the number of shares of Diamond S common stock subject to such award, multiplied by (ii) the exchange ratio set forth in the merger agreement.

As of the effective time of the merger, INSW will assume and convert into restricted shares of INSW (“INSW Restricted Shares”) each outstanding share of restricted stock (collectively, the “Diamond S Restricted Shares”) granted under the Diamond S Equity Plan that is not then vested and does not vest at the effective time of the merger. Each assumed and converted INSW Restricted Share will continue to have, and will be subject to, the same terms and conditions as applied to the applicable Diamond S Restricted Shares immediately prior to the effective time of the merger (but taking into account any changes provided for in the Diamond S Equity Plan, in any applicable award agreement or in such Diamond S Restricted Shares, by reason of the merger agreement or the consummation of the transactions contemplated thereby). As of the effective time of the merger, the number of shares of INSW common stock underlying each such INSW Restricted Share as so assumed and converted (rounded (x) up to the nearest whole share if half a share or more or (y) down to the nearest whole share if less than half a share) will equal the product of (i) the number of shares of Diamond S common stock subject to such award, multiplied by (ii) the exchange ratio set forth in the merger agreement.

Closing and Effectiveness of the Merger

Unless another date is agreed to in writing by INSW and Diamond S, the closing of the merger will take place by conference call and by exchange of signature pages by email or other electronic transmission on the third business day after the satisfaction or waiver of all of the closing conditions set forth in the merger agreement (other than those conditions that by their nature are to be satisfied at the closing).

The merger will become effective when the articles of the merger have been duly filed with the registrar or deputy registrar of corporations of the Republic of the Marshall Islands as provided by the BCA and any other filings, recordings or publications required under the BCA in connection with the merger are made. The date and time at which the merger becomes effective is referred to as the “effective time.” At the effective time, all of the rights, privileges, immunities, powers, purposes, property and assets of each of Merger Sub and Diamond S will vest in the surviving corporation, and all liabilities, obligations and penalties of each of Merger Sub and Diamond S shall be assumed by the surviving corporation.

Conversion of Diamond S Shares

The conversion of shares of Diamond S common stock (other than the excluded shares) into the right to receive the merger consideration will occur automatically at the completion of the merger.

As promptly as practicable following the completion of the merger, and in no event later than the fifth business day after such time, the exchange agent will mail or otherwise provide a letter of transmittal to each holder of record of a certificate that immediately prior to the completion of the merger represented outstanding Diamond S common stock whose shares were converted into the right to receive the merger consideration. The exchange agent will deliver both (1) a letter of transmittal specifying that delivery of certificates will be effected and risk of loss and title to such certificates will pass only upon proper delivery of such certificates (or affidavits of loss in lieu of such certificates) to the exchange agent and (2) instructions for surrendering the certificates (or affidavits of loss in lieu thereof) in exchange for payment of the merger consideration, including any amount payable in respect of the fractional share consideration and any applicable dividends. Similarly, the exchange agent will mail or otherwise provide to each holder of record of non-certificated shares of Diamond S common stock represented by book-entry whose shares of Diamond S common stock were converted into the right to receive the merger consideration, a notice of the

TABLE OF CONTENTS

effectiveness of the merger. Upon surrender of a certificate (or affidavit of loss thereof) for cancellation to the exchange agent and an executed letter of transmittal and without action by a holder of a book-entry share, the holder of such a certificate (or affidavit of loss thereof) or book-entry share is entitled to receive in exchange of such certificate or book-entry share (1) the applicable merger consideration, (2) any fractional share consideration and (3) any cash amounts the holder has the right to receive in respect of dividends or distributions on shares of INSW common stock for each share of Diamond S common stock share formerly represented by the certificate or book-entry share.

At the completion of the merger, the Diamond S stock transfer books will be closed and thereafter no further transfers of shares of Diamond S common stock outstanding may be registered. From the time of the completion of the merger, the holders of certificates outstanding immediately prior to the completion will cease to have any rights with respect to shares of Diamond S common stock.

As of the completion of the merger, all shares of Diamond S common stock will no longer be outstanding and will automatically be cancelled and cease to exist. As of the completion of the merger, each holder of a certificate of book-entry share representing any shares of Diamond S common stock will cease to have any rights with respect thereto, except the right to receive the merger consideration as described above and subject to the terms and conditions set forth in the merger agreement, including the right to receive cash in lieu of fractional shares of INSW common stock which would otherwise be issuable in respect of such shares of Diamond S common stock, together with any dividends, if applicable, without interest.

At any time following twelve (12) months after the effective time, INSW may require the exchange agent to deliver to INSW any undisbursed funds (including any interest received with respect thereto) remaining in the exchange fund and thereafter holders of certificated or book-entry shares shall be entitled to look only to the surviving corporation and INSW (subject to abandoned property, escheat or other similar Laws) as general creditors thereof with respect to the applicable merger consideration, including any amount payable in respect of fractional shares or dividends, without any interest thereon.

Each of INSW and the surviving corporation will be entitled to deduct and withhold, or cause the exchange agent to deduct and withhold, from any amounts otherwise payable pursuant to the merger agreement to any person such amounts as are required to be deducted and withheld with respect to the making of such payment under the Code or any provision of applicable tax law. The parties acknowledged that no deduction or withholding is anticipated but, in the event that such is required, the parties agree to cooperate in good faith to minimize the amount of any deduction or withholding. Any amounts so withheld will be treated for all purposes of the merger agreement as having been paid to the person in respect of which such deduction and withholding was made.

Representations and Warranties

The merger agreement contains representations and warranties made by Diamond S to INSW and by INSW to Diamond S. Certain of the representations and warranties in the merger agreement are subject to materiality or “material adverse effect” qualifications (that is, they will not be deemed to be inaccurate or incorrect unless their failure to be true or correct is material or would result in a “material adverse effect” (as defined below) on the company making such representation or warranty).

Employee Benefits Matters

INSW has agreed to provide each employee of Diamond S or its subsidiaries as of immediately prior to the effective time of the merger (other than certain excluded individuals set forth in Diamond S’ disclosure letter to the merger agreement) (such non-excluded employees, the “Continuing Employees”) with the following: (1) for nine (9) months following the effective time of the merger (or, if earlier, the termination of employment of such Continuing Employee), a base salary or wage level that is no less favorable than the base salary or wage level to which such Continuing Employee was entitled immediately prior to the effective time of the merger and (2) for the period from the effective time of the merger through December 31, 2021 (or, if earlier, the termination of employment of such Continuing Employee), other benefits, perquisites and other compensatory terms that are substantially similar, in the aggregate, to those provided to such Continuing Employees immediately prior to the effective time of the merger. For any Continuing Employee who is terminated by INSW or any applicable subsidiary of INSW without cause on or prior to December 31, 2021 and who is not party to an agreement that provides for a contractual right to severance or other termination benefits, INSW or its applicable subsidiary will provide such Continuing Employee with certain severance payments as set forth in Diamond S’ disclosure letter to the merger agreement.

Following the effective time of the merger and upon the transition of the Continuing Employees to its health and welfare benefits plans (the “New Benefit Plans”), INSW has agreed to use commercially reasonable

105

TABLE OF CONTENTS

efforts to (1) ensure that no limitations or exclusions as to pre-existing conditions, evidence of insurability or good health, waiting periods or actively-at-work exclusions or other limitations or restrictions on coverage are applicable to any Continuing Employees or their dependents or beneficiaries and (2) provide that any costs or expenses incurred by Continuing Employees (and their dependents or beneficiaries) up to (and including) the effective time of the merger shall be taken into account for purposes of satisfying applicable deductible, co-payment, coinsurance, maximum out-of-pocket provisions and like adjustments or limitations on coverage under any such New Benefit Plan.

For purposes of eligibility, participation, vesting, benefit accrual, early retirement subsidies and severance (except to the extent that such credit would result in a duplication of benefits) under the New Benefit Plans and Diamond S benefit plans, INSW shall use commercially reasonable efforts to grant all Continuing Employees from and after the completion of the merger credit for all service with Diamond S, INSW or any of their respective subsidiaries. In order to further an orderly transition and integration, INSW and Diamond S shall use commercially reasonable efforts to cooperate with each other as necessary to enable them to comply with this section of the merger agreement and to furnish to one another such information regarding employment and benefits as may be reasonably requested from time to time.

Combined Company Governance

Board of Directors

The initial board of directors of the combined company following the completion of the merger will have ten members. Prior to the completion of the merger, INSW and Diamond S will each designate, in writing, directors from the persons who currently serve as directors of INSW and Diamond S, so that the INSW Board following the completion of the merger will consist of:

•

An initial chairman designated by INSW;

•

Six additional directors designated by INSW that are reasonably acceptable to Diamond S; and

•

Three additional directors designated by Diamond S that are reasonably acceptable to INSW.

In connection with the merger, the Capital shareholders and the WL Ross shareholders agreed to terminate their existing director designation agreements with Diamond S. As a result, no stockholder of combined company will have a contractual right to designate a director to the board of directors of the combined company.

Committees of the Board of Directors

Each committee of the board of directors of the combined company will initially include one of the directors designated by Diamond S who qualifies as “independent” under the rules and regulations of the SEC and NYSE.

Shareholder Meetings and Recommendations of the INSW and Diamond S Boards of Directors

As promptly as reasonably practicable after the effectiveness of the merger agreement, Diamond S and INSW were required to jointly prepare and cause to be filed with the SEC this joint proxy statement/prospectus in preliminary form and INSW was required to prepare the Form S-4 with respect to the shares of INSW common stock issuable in the merger, which will include this joint proxy statement/prospectus and be filed with the SEC. Diamond S and INSW were required to use their respective reasonable best efforts to (1) make such filings no later than 35 days after the date of the merger agreement, (2) have the Form S-4 declared effective under the Securities Act as promptly as practicable after such filings and thereafter as promptly as practicable mail or deliver the proxy statement/prospectus to their respective stockholders or shareholders, as applicable, (3) ensure that the Form S-4 complies in all material respects with the applicable provisions of the Exchange Act or Securities Act and (4) keep the Form S-4 effective for so long as necessary to complete the merger. If any information relating to Diamond S or INSW, respectively, or any of their respective affiliates, officers or directors, should be discovered by Diamond S or INSW which, in the reasonable judgment of Diamond S or INSW, respectively, should be set forth in an amendment of, or a supplement to, any of the Form S-4 or the proxy statement/prospectus so that any of such documents would

106

TABLE OF CONTENTS

not include any misstatement of a material fact or omit to state any material fact necessary to make the statements therein, in light of the circumstances under which they were made, not misleading, the party who discovers such information will promptly notify the other party, and Diamond S and INSW will cooperate in the prompt filing with the SEC of any necessary amendment of, or supplement to, the proxy statement/prospectus or the Form S-4 and, to the extent required by law, in disseminating the information contained in such amendment or supplement to Diamond S shareholders and INSW stockholders.

Diamond S has agreed to hold the Diamond S special meeting as promptly as practicable after the effectiveness of the Form S-4, in accordance with applicable law and its governing documents and mail the proxy-statement/prospectus to its shareholders entitled to vote at the Diamond S special meeting. Diamond S may only postpone or adjourn the Diamond S special meeting (1) to solicit additional proxies for the purpose of obtaining the Diamond S shareholder approval, (2) for the absence of a quorum and (3) to allow additional time for the filing and/or mailing of any supplemental or amended disclosure to the proxy statement-prospectus that Diamond S has determined is likely to be required under applicable law and for such supplemental or amended disclosure to be disseminated and reviewed by shareowners of Diamond S prior to the Diamond S special meeting. The Diamond S special meeting may not be postponed or adjourned to a date that is in the aggregate more than 30 days after the originally scheduled date of the Diamond S special meeting. Without the prior written consent of INSW, the adoption of the plan of merger will be the only matter (other than matters of procedure, matters required by applicable law to be voted on by Diamond S shareholders in connection with the authorization of the plan of merger) that Diamond S will propose to be acted on by Diamond S shareholders at the Diamond S special meeting.

INSW has agreed to hold the INSW special meeting as promptly as practicable after the effectiveness of the Form S-4, in accordance with applicable law and its governing documents and mail the joint proxy statement/prospectus to INSW stockholders entitled to vote at the INSW special meeting. INSW may only postpone or adjourn the INSW special meeting (1) to solicit additional proxies for the purpose of obtaining the INSW shareowner approval, (2) for the absence of a quorum and (3) to allow additional time for the filing and/or mailing of any supplemental or amended disclosure to the proxy statement-prospectus that INSW has determined is likely to be required under applicable law and for such supplemental or amended disclosure to be disseminated and reviewed by INSW stockholders prior to the INSW special meeting. The INSW special meeting may not be postponed or adjourned to a date that is in the aggregate more than 30 days after the originally scheduled date of the INSW special meeting. Without the prior written consent of Diamond S, the INSW share issuance will be the only matter (other than matters of procedure, matters required by applicable law to be voted on by INSW stockholders in connection with the authorization of the plan of merger) that INSW will propose to be acted on by INSW stockholders at the INSW special meeting.

Diamond S and INSW will use their respective reasonable best efforts to hold the Diamond S special meeting and the INSW special meeting as closely together in time as practicable and on the same date and as soon as reasonably practicable after the date of the merger agreement.

Agreement Not to Solicit Other Offers

Diamond S and INSW have each agreed not to, and to cause their respective controlled affiliates and its and their respective officers, directors, employees, and representatives not to, directly or indirectly:

•

solicit, initiate or knowingly encourage or knowingly facilitate any inquiry, proposal or offer, or the making, submission, modification or amendment or announcement of any inquiry, proposal or offer (including any inquiry, proposal or offer to its stockholders) which constitutes or would be reasonably expected to lead to a proposal or offer made by a person or group (other than Diamond S or INSW or any of its subsidiaries) at any time, including any amendment or modification to any existing proposal or offer, pursuant to which if consummated such person or group would acquire ownership or beneficial ownership (as defined in Rule 13d-3 under the Exchange Act) of at least 20% of the assets of Diamond S or INSW (based on a fair market value on a consolidated basis), at least 20% of the outstanding shares of Diamond S common stock or shares of INSW common stock or businesses of Diamond S or INSW representing at least 20% of Diamond S’ or INSW’s net income or net revenues (on a consolidated basis for the 12-month period ending on the last day of Diamond S’ or INSW’s most recently completed fiscal quarter for which financial statements are

107

TABLE OF CONTENTS

available) (whether pursuant to a merger, consolidation or other business combination, sale of shares of capital stock, sale of assets, tender offer or exchange offer or otherwise, including any single or multi step transaction or series of related transactions), in each case other than the merger, or that is a merger, consolidation, recapitalization or other similar transaction that if consummated would result in the stockholders of Diamond S or INSW immediately preceding such transaction holding less than 80% of the equity interests of the surviving or resulting entity of such transaction, in each case other than the merger (the foregoing described proposal or offer is referred to as a Diamond S or INSW competing proposal);

•

participate in or engage in any negotiations or discussions (other than to state that they are not permitted to have discussions) regarding, or furnish to any person any nonpublic information relating to Diamond S or INSW or any of their respective subsidiaries in connection with, any inquiry, proposal or offer which constitutes or would be reasonably expected to lead to a Diamond S or INSW competing proposal;

•

except in the Diamond S Board or INSW Board has determined in good faith after consultation with outside legal counsel that the failure to take such action would be reasonably likely to constitute a breach of the fiduciary duties of the members of the Diamond S Board or INSW Board under applicable Republic of the Marshall Islands law, waive, terminate, modify or release any person (other than Diamond S or INSW, Merger Sub or any of their respective subsidiaries) from any provision of, or grant any permission, waiver or request under, or fail to enforce, any “standstill” or similar agreement or obligation; provided that Diamond S and INSW will notify the other party promptly (and in any event within 24 hours of any such waiver, termination, modification, release or grant of permission, waiver or request);

•

fail to include the Diamond S Board or INSW Board recommendation in the joint proxy statement/prospectus;

•

resolve or agree to do any of the foregoing acts or failures to act described in bullet points four through seven (which is referred to as a board recommendation change).

108

TABLE OF CONTENTS

the material terms and conditions of such request or proposal (including any changes thereto) and the identity of the person making such request or proposal, (2) provide the other party, as soon as reasonably practicable, copies of all correspondence and other written materials exchanged with the person making such request or proposal or its representatives that describes or contains any such request or proposal and (3) keep the other party reasonably informed of the status and details (including amendments or proposed amendments) of any such request or proposal on a reasonably current basis.

For purposes of the merger agreement, a “superior proposal” means any bona fide written proposal (on its most recently amended or modified terms, if amended or modified) made by a third party to enter into an alternative transaction (with references to 20% and 80% being deemed to be replaced with references to 50%) that, taking into account all financial, regulatory, legal and other aspects of such proposal and whether the proposal is fully financed, as well as the identity of the person making the competing proposal, (1) is more favorable to the stockholders of Diamond S or INSW from a financial point of view than the merger, taking into account all relevant factors (including any adjustment to the terms and conditions proposed by Diamond S or INSW in response to such proposal), and (2) is reasonably capable of being completed as proposed on a timely basis.

Prior to the Diamond S or INSW making a change of recommendation, Diamond S or INSW will provide the other with five business days’ prior written notice (it being understood and agreed that any material amendment to the applicable competing proposal will require a new notice and an additional two business-day period) advising INSW or Diamond S that its board of directors intends to take such action and contemporaneously providing the other party with a copy of the superior proposal, a copy of any proposed agreements for such superior proposal (including any financing commitments related thereto) and indicating the identity of the person making such competing proposal (or, in each case, if not provided in writing, a written summary of the terms thereof), and during such initial five business-day or subsequent two business-day period, (a) Diamond S or INSW will negotiate, and cause its representatives to negotiate, with the other party and its representatives in good faith (to the extent that the other party wishes to negotiate) to enable the other party to determine whether to propose revisions to the terms of the merger agreement or any other agreement related to the transactions such that the competing proposal would no longer constitute a superior proposal and (b) Diamond S or INSW will consider in good faith any proposal by the other party to amend the terms and conditions of the merger agreement or any other agreement related to the transactions such that such competing proposal would no longer constitute a superior proposal.

None of the foregoing will prohibit Diamond S or INSW from disclosing to its stockholders a position contemplated by Rule 14d-9 or Rule 14e-2(a) promulgated under the Exchange Act, or from issuing a “stop, look and listen” statement or similar communication of the type contemplated by Rule 14d-9(f) under the Exchange Act pending disclosure of its position thereunder; provided that any such disclosure or statement that constitutes or contains a board recommendation change will be subject to the restrictions described above.

Indemnification; Exculpation and Insurance

For a period of six years after the effective time, INSW will cause the combined company to indemnify and hold harmless all past and present directors and officers of Diamond S and its subsidiaries (collectively, the “indemnified parties”) to the fullest extent permitted by applicable law against any costs or expenses, judgments, fines, losses, claims, damages, liabilities and amounts paid in settlement (including advancing reasonable fees and expenses in advance of the final disposition) of any actual or threatened claim, action, suit, proceeding or investigation as a result of such indemnified party’s service as a director or officer of Diamond S or its subsidiary. However each indemnified party must agree in advance to return any such funds to which a court of competent jurisdiction has determined in a final, non-appealable judgment such indemnified party is not ultimately entitled to indemnification or advancement.

All rights to indemnification, exculpation and advancement in existence on March 30, 2021 will remain in effect for six years and following the completion of the merger and no such rights may be amended, modified or repealed in any manner that would adversely affect the rights or protections thereunder of any such indemnified party.

109

TABLE OF CONTENTS

INSW will cause the combined company to maintain, for an aggregate period of not less than six years from the effective time, the current directors’ and officers’ liability insurance policy maintained by Diamond S with respect to claims arising from facts or events occurring at or prior to the effective time unless Diamond S elects to obtain a tail insurance policy prior to the effective time; however, the combined company need not expend more than 400% of the last annual premium for such policy.

•

each of Diamond S and INSW must use its commercially reasonable efforts to have any conditions of class on vessels removed and ensure that vessels maintain inventories of critical usable spares in accordance with its manager’s safety management systems.

Pre-Merger Dividends

INSW may declare and set the record date for, and pay, the $31.5 million special dividend and declare and pay the INSW FSO dividend. It is expected that INSW will declare and pay the INSW special dividend prior to the closing of the merger, with a record date on or after the date of the INSW special meeting.

Amendment and Waiver

Amendment

Subject to compliance with applicable law, the merger agreement may be amended by mutual agreement of the parties in writing at any time before or after receipt of the requisite stockholder approvals; provided that any amendment of the merger agreement that requires the approval by Diamond S shareholders or INSW stockholders, as applicable, under applicable law, will be subject to such approval.

Waiver

At any time prior to the completion of the merger, a party may, in writing, (1) extend the time for performance of any obligation or act of the other party, (2) waive any inaccuracy in a representation or warranty of the other party or (3) waive compliance by the other party with any of the agreements or conditions for the benefit of such party contained in the merger agreement. Any agreement on the part of INSW or Diamond S to any such extension or waiver will be valid only if set forth in an instrument in writing signed on behalf of INSW or Diamond S, as applicable. Any delay in exercising any right under the merger agreement will not constitute a waiver of such right.

Specific Performance

The parties to the merger agreement agreed that irreparable injury will occur in the event that any of the provision of the merger agreement is not performed in accordance with its specific terms or is otherwise breached. Therefore each party is entitled to an injunction or injunctions to prevent or remedy any breaches or threatened breaches of the merger agreement by any other party, to a decree or order of specific performance to specifically enforce the terms and provisions of the merger agreement and to any further equitable relief, without any obligation to post a bond in respect thereof. Each party further agreed that there is not an adequate remedy at law for breach of the merger agreement.

Governing Law

INDEBTEDNESS AMENDMENTS

Indebtedness

In connection with the merger, lenders under Diamond S’ existing debt agreements, described below, have agreed, among other things, to consent to the merger and waive any existing default or event of default and any default or event of default that would arise as a result of the merger, pursuant to the debt consent letters (as defined below). Lenders under Diamond S’ $360 Million Nordea Facility and $525 Million Nordea Facility (each defined below) have entered into amendment and restatement agreements to amend the terms of such existing debt agreements to more closely mirror the terms of INSW’s credit facilities. In addition, INSW has agreed to become a credit party to the A&R debt agreements (as defined below) and to provide a guaranty of Diamond S’ obligations under the A&R debt agreements.

$525 Million Nordea Facility

On December 27, 2019, Diamond S refinanced certain of its existing indebtedness with the proceeds of a new credit agreement, dated December 23, 2019 (the “$525 Million Nordea Facility”), by and among Diamond S, Nordea Bank Abp, New York Branch (“Nordea”), as administrative agent and collateral agent, and each of the lenders from time to time party thereto, consisting of a $375 million term loan and a $150 million revolving credit facility. The $525 Million Nordea Facility bears interest at LIBOR plus a margin of 2.5%, with interest paid quarterly, and matures on December 27, 2024. Commitment fees on undrawn amounts related to the revolving loan component of the $525 Million Nordea Facility are 0.875%. The repayment profile reflects a 17-year, age-adjusted amortization with the first amortization period beginning on March 31, 2020. The $525 Million Nordea Facility is secured by, inter alia, mortgages over ten Suezmax vessels and 26 medium range vessels.

In connection with the merger agreement signing, Diamond S, Nordea and the lenders under the $525 Million Nordea Facility entered into a consent letter dated March 30, 2021 (the “525 consent letter”), pursuant to which the lenders party thereto consented to the merger and waived any existing default or event of default and any default or event of default that would arise as a result of the merger. Pursuant to the terms of the 525 consent letter, in connection with the consummation of the merger, the parties thereto entered into an amendment and restatement agreement dated May 27, 2021 (the “525 Nordea A&R debt agreement”), pursuant to which the $525 Million Nordea Facility shall be amended and restated upon the consummation of the merger (and upon the satisfaction of certain other customary conditions precedent) to more closely mirror the representations, warranties and covenants of INSW’s credit facilities and to include INSW as a credit party. In addition, INSW has executed a guaranty of Diamond S’ obligations under the 525 Nordea A&R debt agreement, which guaranty will become effective simultaneously with the amendment and restatement of the $525 Million Nordea Facility as contemplated under the 525 Nordea A&R debt agreement. The 525 Nordea A&R debt agreement includes covenants relating to, among other things, the ability to incur indebtedness, the ability to pay dividends, maintaining a minimum cash balance, collateral maintenance, maintaining a net debt to capitalization ratio and other customary restrictions. The 525 Nordea A&R debt agreement also provides for customary events of default. Effectiveness of the 525 Nordea A&R debt agreement is a condition to the consummation of the merger.

Each lender under the $525 Million Nordea Facility which provided its consent to the merger and executed and delivered the 525 Nordea A&R debt agreement will receive a non-refundable consent fee equal to 0.20% of the aggregate principal amount of loans made available by such lender (including any undrawn commitment) which fee will be due and payable on the completion of the merger and paid by Diamond S.

$360 Million Nordea Facility

On March 27, 2019, Diamond S entered into a $360 million five-year senior secured term loan and revolving credit facility (the “$360 Million Nordea Facility”) among Diamond S, Nordea, as administrative agent and collateral agent, and each of the lenders from time to time party thereto. The $360 Million Nordea Facility provides for borrowings of up to $360 million and is secured by mortgages over 26 collateral vessels (the “360 vessels”). Loans under the $360 Million Nordea Facility are available in two tranches consisting of an up to $300 million term loan and up to $60 million in revolving loans, for an aggregate amount not to exceed the lesser of 65% of the fair market value of the 360 vessels and $360 million. Diamond

TABLE OF CONTENTS

S’ borrowings under the $360 Million Nordea Facility bear interest at the LIBOR rate with three- or six-month interest periods, plus a margin of 2.65% per annum. Commitment fees on undrawn amounts are 40% of the margin. The secured term loan must be repaid in equal consecutive quarterly installments in an amount that reflects a straight-line amortization reducing the principal amount to $0 upon the 360 vessels having achieved an average age of 17 years. The revolving loans and any outstanding amounts under the term loan mature on March 27, 2024.

In connection with the merger agreement signing, Diamond S, Nordea and the lenders under the $360 Million Nordea Facility entered into a consent letter dated March 30, 2021 (the “360 consent letter”), pursuant to which the lenders party thereto consented to the merger and waived any existing default or event of default and any default or event of default that would arise as a result of the merger. Pursuant to the terms of the 360 consent letter, in connection with the consummation of the merger, the parties thereto entered into an amendment and restatement agreement dated May 27, 2021 (the “360 Nordea A&R debt agreement” and together with the 525 Nordea A&R debt agreement, the “A&R debt agreements”), pursuant to which the $360 Million Nordea Facility shall be amended and restated upon the consummation of the merger (and upon the satisfaction of certain other customary conditions precedent) to more closely mirror the representations, warranties and covenants of INSW’s credit facilities and to include INSW as a credit party. In addition, INSW has executed a guaranty of Diamond S’ obligations under the 360 Nordea A&R debt agreement, which guaranty will become effective simultaneously with the amendment and restatement of the $360 Million Nordea Facility as contemplated by the 360 Nordea A&R debt agreement. The 360 Nordea A&R debt agreement includes covenants relating to, among other things, the ability to incur indebtedness, the ability to pay dividends, maintaining a minimum cash balance, collateral maintenance, maintaining a net debt to capitalization ratio and other customary restrictions. The 360 Nordea A&R debt agreement also provides for customary events of default. Effectiveness of the 360 Nordea A&R debt agreement is a condition to the consummation of the merger.

Each lender under the $360 Million Nordea Facility which provided its consent to the merger and executed and delivered the 360 Nordea A&R debt agreement will receive a non-refundable consent fee equal to 0.20% of the aggregate principal amount of loans made available by such lender (including any undrawn commitment) which fee will be due and payable on the completion of the merger and paid by Diamond S.

NT Suez Joint Venture Facility

On August 9, 2016, the venture 51% owned by Diamond S, NT Suez Holdco LLC (“NT Suez”), entered into a $66 million five-year senior secured term loan facility (the “NT Suez Facility”) for the purpose of financing two vessels owned by NT Suez. The NT Suez Facility, which is collateralized by the two vessels owned by NT Suez, is a nonrecourse term loan with reductions that are based on a 15-year amortization schedule and are payable on a quarterly basis. Interest is paid quarterly, and the NT Suez Facility bears interest at the LIBOR rate for a three-month interest period, plus a 3.25% interest rate margin. The NT Suez Facility includes restrictions and financial covenants including, among other things, NT Suez’s ability to incur indebtedness, limitations on dividends, minimum cash balance, collateral maintenance, and other customary restrictions.

In connection with the merger, lenders under the NT Suez Facility have agreed pursuant to a consent and amendment letter dated March 30, 2021 (the “NT Suez debt consent” and together with the 360 consent letter and the 525 consent letter, the “debt consent letters”), among other things, to consent to the merger (including waiving a mandatory prepayment that would otherwise be triggered by the merger) and waive any existing event of default and any event of default that would arise as a result of the merger. In addition, lenders under the NT Suez Facility have agreed to amend the definition of “change of control” upon the closing of the merger to reflect the ownership structure of INSW and its subsidiaries.

Each lender under the NT Suez Facility which provided its consent under the NT Suez debt consent will receive a non-refundable consent fee equal to 0.20% of the aggregate principal amount of loans of such lender which fee will be due and payable on the completion of the merger and paid by NT Suez.

INSW SPECIAL MEETING

General

This joint proxy statement/prospectus is being provided to INSW stockholders as part of a solicitation of proxies by the INSW Board for use at the INSW special meeting to be held at the time and place specified below and at any properly convened meeting following an adjournment or postponement thereof. This joint proxy statement/prospectus provides INSW stockholders with information they need to know to be able to vote or instruct their vote to be cast at the INSW special meeting.

Date, Time and Place

The INSW special meeting will be conducted solely as a virtual meeting via the Internet at www.virtualshareholdermeeting.com/INSW2021SM on July 13, 2021 at 10:00 a.m.. INSW intends to mail this joint proxy statement/prospectus and the enclosed form of proxy to its shareowners entitled to vote at the INSW special meeting on or about June 11, 2021.

Purpose of the INSW Special Meeting

At the INSW special meeting, INSW stockholders will be asked to consider and vote on the following:

Approval of the INSW Share Issuance. To vote on a proposal to approve the issuance of INSW common stock, no par value, to Diamond S shareholders in connection with the merger contemplated by merger agreement; and

Adjournment of the INSW Special Meeting. To vote on a proposal to approve the adjournment of the INSW special meeting to a later date or dates, if necessary or appropriate, to solicit additional proxies in the event there are not sufficient votes at the time of the INSW special meeting to approve the INSW share issuance proposal.

Recommendation of the INSW Board

On March 30, 2021, the INSW Board unanimously approved and declared advisable the merger agreement and the transactions contemplated by the merger agreement, including the merger, and determined that the merger agreement and the transactions contemplated by the merger agreement, including the merger, certain governance arrangements and the INSW share issuance, are advisable and fair to and in the best interests of INSW and its stockholders. Accordingly, the INSW Board unanimously recommends that INSW stockholders vote “FOR” the INSW share issuance proposal and “FOR” the INSW adjournment proposal.

INSW stockholders should carefully read this joint proxy statement/prospectus, including any documents incorporated by reference, and the annexes in their entirety for more detailed information concerning the merger and the other transactions contemplated by the merger agreement.

INSW Record Date; INSW Stockholders Entitled to Vote

Only holders of record of INSW common stock at the close of business on June 11, 2021 will be entitled to notice of, and to vote at, the INSW special meeting or any adjournments or postponements thereof.

As of June 1, 2021, there were 28,087,011 shares of INSW common stock outstanding and entitled to vote at the INSW special meeting. Each share of INSW common stock outstanding on the INSW record date entitles the holder thereof to one vote on each proposal to be considered at the INSW special meeting, in person or by proxy through the Internet or by telephone or by a properly executed and delivered proxy with respect to the INSW special meeting.

Your vote is important. We expect that many INSW stockholders will not attend the INSW special meeting virtually, and instead will be represented by proxy. Most INSW stockholders have a choice of voting over the Internet, by using a toll-free telephone number, or by returning a completed INSW proxy

card or voting instruction form. Please check your notice, proxy card or the information forwarded by your broker, bank or other holder of record to see which options are available to you. The Internet and telephone voting procedures have been designed to authenticate INSW stockholders, to allow you to vote your shares, and to confirm that your instructions have been properly recorded. The Internet and telephone voting facilities for INSW stockholders of record will close at 11:59 p.m. Eastern Time on July 12, 2021. If your shares are held through a broker, bank or other holder of record, and Internet or telephone facilities are made available to you, these facilities may close sooner than those for INSW stockholders of record.

You can revoke your proxy at any time before it is exercised by delivering a properly executed, later-dated proxy (including an Internet or telephone vote) or by voting virtually at the INSW special meeting. Executing your proxy in advance will not limit your right to vote at the INSW special meeting if you decide to attend in person (via the virtual meeting website). However, if your shares are held in the name of a broker, bank or other holder of record, you cannot vote at the INSW special meeting virtually unless you have a legal proxy, executed in your favor, from the holder of record.

All shares of INSW common stock entitled to vote and represented by properly executed proxies received prior to the INSW special meeting and not revoked will be voted at the INSW special meeting in accordance with your instructions. If you sign and return your proxy but do not indicate how your shares of INSW common stock should be voted on a proposal, the shares represented by your proxy will be voted as the INSW Board recommends for such proposal.

A complete list of INSW stockholders entitled to vote at the INSW special meeting will be available for examination by any INSW stockholder in the Corporate Secretary’s office at International Seaways, Inc., 600 Third Avenue, 39th Floor, New York, New York 10016 for purposes pertaining to the INSW special meeting, during ordinary business hours for a period of ten days before the INSW special meeting, and at the time and place of the INSW special meeting.

Quorum; Adjournment

The INSW by-laws provide that the holders of a majority of the outstanding shares of INSW common stock as of the INSW record date, present either in person or by proxy and entitled to vote, will constitute a quorum for the transaction of business at the INSW special meeting. Abstentions will count for the purpose of determining the presence of a quorum for the transaction of business at the INSW special meeting. Broker non-votes, if any, will not be counted for the purpose of determining the presence of a quorum for the transaction of business at the INSW special meeting.

Subject to certain restrictions contained in the merger agreement, the INSW special meeting may be adjourned to allow additional time for obtaining additional proxies. No notice of an adjourned meeting need be given if the time and place thereof are announced at the INSW special meeting at which the adjournment was taken unless:

•

the adjournment is for more than thirty (30) days, in which case a notice of the adjourned meeting will be given to each INSW stockholder of record entitled to vote at the INSW special meeting; or

•

if, after the adjournment, a new record date for determination of INSW stockholders entitled to vote is fixed for the adjourned meeting, in which case the INSW Board will fix as the record date for determining INSW stockholders entitled to notice of such adjourned meeting the same or an earlier date as that fixed for determination of INSW stockholders entitled to vote at the adjourned meeting, and will give notice of the adjourned meeting to each INSW stockholder of record as of such record date.

At any subsequent reconvening of the INSW special meeting at which a quorum is present, any business may be transacted which properly could have been transacted at the original INSW special meeting, and all proxies will be voted in the same manner as they would have been voted at the original convening of the INSW special meeting, except for any proxies that have been effectively revoked or withdrawn prior to the adjourned meeting.

122

TABLE OF CONTENTS

Required Vote

The required votes to approve the INSW proposals are as follows:

•

The INSW share issuance proposal requires the affirmative vote of the holders of a majority of the outstanding shares of INSW common stock present and entitled to vote at the INSW special meeting.

•

The INSW adjournment proposal requires the affirmative vote of the holders of a majority of the outstanding shares of INSW common stock present and entitled to vote at the INSW special meeting.

Treatment of Abstentions; Failure to Vote

For purposes of the INSW special meeting, an abstention occurs when a INSW stockholder attends the INSW special meeting, either in person (via the special meeting website) or by proxy, but abstains from voting. For each of the INSW share issuance proposal and the INSW adjournment proposal, if a INSW stockholder present in person (via the virtual meeting website) at the INSW special meeting abstains from voting, or responds by proxy with an “abstain” vote, it will have the same effect as a vote cast “AGAINST” such proposal. If a INSW stockholder is not present in person at the INSW special meeting and does not respond by proxy, it will have no effect on the vote count for such proposal.

Shares Held in Street Name

If your shares of INSW common stock are held in an account at a bank, broker or other nominee holder of record (i.e., in “street name”), you must provide the record holder of your shares with instructions on how to vote the shares. Please follow the voting instructions provided by the bank, broker or other nominee. You may not vote shares held in street name by returning a INSW proxy card directly to INSW or by voting in person at the INSW special meeting unless you provide a “legal proxy,” which you must obtain from your bank, broker or other nominee. Further, banks, brokers or other nominees who hold shares of INSW common stock on behalf of their customers may not give a proxy to INSW to vote those shares with respect to the INSW share issuance proposal and the INSW adjournment proposal without specific instructions from their customers, as banks, brokers and other nominees do not have discretionary voting power on these “non-routine” matters. Under the current rules of the NYSE, each of the proposals to be considered at the INSW special meeting as described in this joint proxy statement/prospectus are considered non-routine. Therefore banks, brokers and other nominee holders of record do not have discretionary authority to vote on any of the proposals to be considered at the INSW special meeting. Broker non-votes occur when a broker or nominee is not instructed by the beneficial owner of shares to vote on a particular proposal for which the broker does not have discretionary voting power.

Therefore, if you are a INSW stockholder and you do not instruct your bank, broker or other nominee on how to vote your shares, your bank, broker or other nominee may not vote your shares on the INSW share issuance proposal or the INSW adjournment proposal, which broker non-votes, if any, will have no effect on the vote count for such proposal.

Voting by INSW’s Board of Directors and Executive Officers

As of the close of business on June 1, 2021, the most recent practicable date for which such information was available, directors and executive officers of INSW and their affiliates owned and were entitled to vote 919,108 shares of INSW common stock, or approximately 3.3% of the shares of common stock outstanding on that date. The number and percentage of shares of INSW common stock owned by directors and executive officers of INSW and their affiliates as of the INSW record date are not expected to be meaningfully different from the number and percentage as of June 1, 2021. It is currently expected that INSW’s directors and executive officers will vote their shares of INSW common stock in favor of each of the proposals to be considered at the INSW special meeting, although none of them have entered into any agreements obligating them to do so. For information with respect to INSW common stock owned by directors and executive officers of INSW, please see the section entitled “Certain Beneficial Owners of INSW Common Stock.”

Solicitation of Proxies; Expenses of Solicitation

To assist in the solicitation of proxies, INSW has retained Innisfree, for a fee of $20,000 plus reimbursement of out-of-pocket expenses for their services and a fee of $5.50 per call with individual investors.

INSW PROPOSAL 1 — THE INSW SHARE ISSUANCE PROPOSAL

This joint proxy statement/prospectus is being furnished to the INSW stockholders as part of the solicitation of proxies by the INSW Board for the INSW special meeting to consider and vote upon a proposal to approve the INSW share issuance proposal pursuant to the merger agreement, which is attached as Annex A to this joint proxy statement/prospectus.

The INSW Board, after due and careful discussion and consideration, unanimously adopted, approved and declared advisable the merger agreement and the other transactions contemplated by the merger agreement, including the issuance of shares of INSW common stock as merger consideration (referred to as the INSW share issuance).

Required Vote of Stockholders

The INSW Board unanimously recommends that INSW stockholders vote “FOR” the proposal to approve the INSW share issuance proposal.

Approval of the INSW share issuance proposal is a condition to completion of the merger.

The vote on the INSW share issuance proposal is a vote separate and apart from the vote to approve the INSW adjournment proposal. Accordingly, a INSW stockholder may vote to approve the INSW share issuance proposal and vote not to approve the INSW adjournment proposal, and vice versa.

Assuming a quorum is present, approval of the INSW share issuance proposal requires the affirmative vote of the holders of a majority of the outstanding shares of INSW common stock present and entitled to vote at the INSW special meeting.

Pursuant to the Cyrus Support Agreement, Cyrus (which collectively with its affiliated entities beneficially owned approximately 14.3% of the outstanding shares of INSW common stock as of June 1, 2021), has agreed, subject to the terms and conditions thereof, to vote their shares of INSW common stock in favor of the INSW share issuance proposal.

INSW is asking its stockholders to authorize the holder of any proxy solicited by the INSW Board to vote in favor of any adjournment of the INSW special meeting to solicit additional proxies if there are not sufficient votes to approve the INSW share issuance proposal or to ensure that any supplement or amendment to this joint proxy statement/prospectus is timely provided to INSW stockholders.

Required Vote of Stockholders

The INSW Board unanimously recommends that INSW stockholders vote “FOR” the INSW adjournment proposal, if necessary.

The vote on the INSW adjournment proposal is a vote separate and apart from the vote to approve the INSW share issuance proposal. Accordingly, a INSW stockholder may vote to approve the INSW share issuance proposal and vote not to approve the INSW adjournment proposal, and vice versa.

DIAMOND S SPECIAL MEETING

This joint proxy statement/prospectus is being provided to the Diamond S shareholders as part of a solicitation of proxies by the Diamond S Board for use at the Diamond S special meeting to be held at the time and place specified below and at any properly convened meeting following an adjournment or postponement thereof. This joint proxy statement/prospectus provides Diamond S shareholders with information they need to know to be able to vote or instruct their vote to be cast at the Diamond S special meeting.

Time and Place

The Diamond S special meeting will be conducted solely as a virtual meeting via the Internet at www.virtualshareholdermeeting.com/DSSI2021SM, July 13, 2021 at 10:00 a.m. Eastern Time. Diamond S intends to mail this joint proxy statement/prospectus and the enclosed form of proxy to its shareholders entitled to vote at the Diamond S special meeting on or about June 11, 2021.

Purpose of the Diamond S Special Meeting

At the Diamond S special meeting, Diamond S shareholders will be asked to consider and vote on the following:

Authorization and Approval of the Merger Agreement. To vote on a proposal to authorize and approve the merger agreement, which is further described in the section entitled “The Merger Agreement,” and a copy of which merger agreement is attached as Annex A to this joint proxy statement/prospectus;

Diamond S Advisory Compensation. To vote on a proposal to approve, by advisory (non-binding) vote, certain compensation arrangements that may be paid or become payable to Diamond S named executive officers in connection with the merger contemplated by the merger agreement; and

Completion of the merger is conditioned on the approval of the Diamond S merger proposal.

Recommendation of the Diamond S Board

On March 30, 2021, the Diamond S Board unanimously approved and declared advisable the merger agreement and the transactions contemplated by the merger agreement, including the merger, and determined that the merger agreement and the transactions contemplated by the merger agreement, including the merger, are fair to and in the best interests of Diamond S and its shareholders. Accordingly, the Diamond S Board unanimously recommends that Diamond S shareholders vote “FOR” the Diamond S merger proposal, “FOR” the Diamond S advisory compensation proposal and “FOR” the Diamond S adjournment proposal.

Diamond S shareholders should carefully read this joint proxy statement/prospectus, including any documents incorporated by reference, and the annexes in their entirety for more detailed information concerning the merger and the other transactions contemplated by the merger agreement.

Diamond S Record Date; Diamond S Shareholders Entitled to Vote

Only holders of record of Diamond S common stock at the close of business on June 11, 2021 will be entitled to notice of, and to vote at, the Diamond S special meeting or any adjournments or postponements thereof.

As of the close of business on June 1, 2021, there were 40,612,811 shares of Diamond S common stock outstanding and entitled to vote at the Diamond S special meeting. Each share of Diamond S common stock outstanding on the Diamond S record date entitles the holder thereof to one vote on each proposal to be

128

TABLE OF CONTENTS

considered at the Diamond S special meeting, in person (via the virtual meeting website) or by proxy through the Internet or by telephone or by a properly executed and delivered proxy with respect to the Diamond S special meeting.

Your vote is important. We expect that many Diamond S shareholders will not attend the Diamond S special meeting in person (via the virtual meeting website), and instead will be represented by proxy. Most Diamond S shareholders have a choice of voting over the Internet, by using a toll-free telephone number, or by returning a completed proxy card or voting instruction form. Please check your notice, proxy card or the information forwarded by your broker, bank or other holder of record to see which options are available to you. The Internet and telephone voting procedures have been designed to authenticate shareholders, to allow you to vote your shares, and to confirm that your instructions have been properly recorded. The Internet and telephone voting facilities for Diamond S shareholders of record will close at 11:59 p.m. Eastern Time on July 12, 2021. If your shares are held through a broker, bank or other holder of record and Internet or telephone facilities are made available to you, these facilities may close sooner than those for Diamond S shareholders of record.

You can revoke your proxy at any time before it is exercised by delivering a properly executed, later-dated proxy (including an Internet or telephone vote) or by voting virtually at the Diamond S special meeting. Executing your proxy in advance will not limit your right to vote virtually at the Diamond S special meeting if you decide to attend in person (via the virtual meeting website). However, if your shares are held in the name of a broker, bank or other holder of record, you cannot vote at the Diamond S special meeting unless you have a legal proxy, executed in your favor, from the holder of record.

All shares of Diamond S common stock entitled to vote and represented by properly executed proxies received prior to the Diamond S special meeting and not revoked will be voted at the Diamond S special meeting in accordance with your instructions. If you sign and return your proxy but do not indicate how your shares of Diamond S common stock should be voted on a proposal, the shares represented by your proxy will be voted as the Diamond S Board recommends for such proposal.

A complete list of Diamond S shareholders entitled to vote at the Diamond S special meeting will be available for examination by any Diamond S shareholder in the Corporate Secretary’s office at Diamond S’ corporate office at Diamond S Shipping Inc., 33 Benedict Place, Greenwich, Connecticut 06830 for purposes pertaining to the Diamond S special meeting, during ordinary business hours for a period of ten days before the Diamond S special meeting, and during the Diamond S special meeting, and at the time and place of the Diamond S special meeting.

Quorum

The Diamond S by-laws provide that the holders of a majority of the shares issued and outstanding and entitled to vote at the Diamond S special meeting, present in person (via the virtual meeting website) or represented by proxy, will constitute a quorum for the transaction of business at the Diamond S special meeting.

Abstentions will count for the purpose of determining the presence of a quorum for the transaction of business at the Diamond S special meeting.

Broker non-votes, if any, will not be counted for the purpose of determining the presence of a quorum for the transaction of business at the Diamond S special meeting.

Adjournments

Subject to certain restrictions contained in the merger agreement, the Diamond S special meeting may be adjourned to allow additional time for obtaining additional proxies.

At any subsequent reconvening of the Diamond S special meeting at which a quorum is present, any business may be transacted which properly could have been transacted at the original Diamond S special meeting, and all proxies will be voted in the same manner as they would have been voted at the original convening of the Diamond S special meeting, except for any proxies that have been effectively revoked or withdrawn prior to the adjourned meeting.

129

TABLE OF CONTENTS

Required Vote

The required votes to approve the Diamond S proposals are as follows:

•

The Diamond S advisory compensation proposal requires the affirmative vote of holders of a majority of the shares of Diamond S common stock represented in person (via the virtual meeting website) or by proxy at the Diamond S special meeting and entitled to vote on the proposal, assuming a quorum. Because the vote on the Diamond S merger-related compensation proposal is advisory only, it will not be binding on either Diamond S or INSW.

•

Accordingly, if the Diamond S merger proposal is approved and the merger is completed, the merger-related compensation will be payable to Diamond S’ named executive officers, subject only to the conditions applicable thereto, regardless of the outcome of the approval of the Diamond S advisory compensation proposal.

•

Treatment of Abstentions; Failure to Vote

For purposes of the Diamond S special meeting, an abstention occurs when a Diamond S shareholder attends the Diamond S special meeting, either in person (via the virtual meeting website) or by proxy, but abstains from voting.

•

For the Diamond S merger proposal, if a Diamond S shareholder present in person (via the virtual meeting website) at the Diamond S special meeting abstains from voting, or responds by proxy with an “abstain” vote, it will have the effect of a vote cast “AGAINST” such proposal. If a Diamond S shareholder is not present in person (via the virtual meeting website) at the Diamond S special meeting and does not respond by proxy, it will have the effect of a vote cast “AGAINST” such proposal.

•

For the Diamond S advisory compensation proposal, if a Diamond S shareholder present in person (via the virtual meeting website) at the Diamond S special meeting abstains from voting, or responds by proxy with an “abstain” vote, it will have the same effect as a vote cast “AGAINST” such proposal. If a Diamond S shareholder is not present in person (via the virtual meeting website) at the Diamond S special meeting and does not respond by proxy, it will have no effect on the vote count for such proposal (assuming a quorum is present).

•

For the Diamond S adjournment proposal, if a Diamond S shareholder present in person (via the virtual meeting website) at the Diamond S special meeting abstains from voting, or responds by proxy with an “abstain” vote, it will have the same effect as a vote cast “AGAINST” such proposal. If a Diamond S shareholder is not present in person (via the virtual meeting website) at the Diamond S special meeting and does not respond by proxy, it will have no effect on the vote count for such proposal.

Voting by Diamond S’ Board of Directors and Executive Officers

As of the close of business on June 1, 2021, the most recent practicable date for which such information was available, directors and executive officers of Diamond S and their affiliates owned and were entitled to vote 782,962 shares of Diamond S common stock or less than 2.0% of the shares of Diamond S common stock outstanding on that date. The number and percentage of shares of Diamond S common stock owned by directors and executive officers of Diamond S and their affiliates as of the Diamond S record date are not expected to be meaningfully different from the number and percentage as of June 1, 2021. It is currently expected that Diamond S’ directors and executive officers will vote their shares of Diamond S common stock in favor of each of the proposals to be considered at the Diamond S special meeting, but none of them have entered into any agreement obligating them to do so. For information with respect to

DIAMOND S PROPOSAL 1 — DIAMOND S MERGER AGREEMENT PROPOSAL

This proxy statement/prospectus is being furnished to Diamond S shareholders as part of the solicitation of proxies by the Diamond S Board for use at the Diamond S special meeting to consider and vote upon a proposal to authorize and approve the merger agreement, which is attached as Annex A to this joint proxy statement/prospectus, and approve the transactions contemplated thereby, including the merger.

The Diamond S Board, after due and careful discussion and consideration, unanimously adopted, approved and declared advisable the merger agreement, the merger and the other transactions contemplated by the merger agreement and determined that the merger agreement, the merger and the other transactions contemplated by the merger agreement are advisable and fair to, and in the best interests of, Diamond S and its shareholders.

Required Vote of Shareholders

The Diamond S Board accordingly unanimously recommends that Diamond S shareholders vote “FOR” the proposal to authorize and approve the merger agreement and approve the merger, as disclosed in this joint proxy statement/prospectus, particularly the related narrative disclosures in the sections of this joint proxy statement/prospectus entitled “The Merger” and “The Merger Agreement” and as attached as Annex A to this joint proxy statement/prospectus.

Approval of the Merger Proposal is a condition to completion of the merger.

The vote on the Merger Proposal is a vote separate and apart from the vote to approve either the Advisory Compensation Proposal or the Diamond S Adjournment Proposal. Accordingly, a Diamond S shareholder may vote to approve the Merger Proposal and vote not to approve the Advisory Compensation Proposal or the Diamond S Adjournment Proposal, and vice versa.

Approval of the Merger Proposal requires the affirmative vote of holders of a majority of the outstanding shares of Diamond S common stock entitled to vote on the authorization of the merger agreement at the Diamond S special meeting in favor of such authorization. A failure to vote, a broker non-vote or an abstention will have the same effect as a vote “AGAINST” the Merger Proposal.

DIAMOND S PROPOSAL 2 — THE ADVISORY COMPENSATION PROPOSAL

Diamond S is asking its shareholders to approve, on an advisory (non-binding) basis, the compensation that will or may be paid to Diamond S’ named executive officers in connection with the merger. Because the vote on the Advisory Compensation Proposal is advisory only, it will not be binding on either Diamond S or INSW. Accordingly, if the Merger Proposal is approved and the merger is completed, the merger-related compensation will be payable to Diamond S’ named executive officers, subject only to the conditions applicable thereto, regardless of the outcome of the approval of the Advisory Compensation Proposal.

Required Vote of Shareholders

The Diamond S Board unanimously recommends that Diamond S shareholders vote “FOR” the proposal to approve the Advisory Compensation Proposal.

Approval of the Advisory Compensation Proposal requires the affirmative vote of the holders of a majority of the shares of Diamond S common stock represented in person (via the virtual meeting website) or by proxy at the Diamond S special meeting and entitled to vote on the proposal at the Diamond S special meeting, assuming a quorum.

Accordingly, a failure to vote or a broker non-vote will have no effect on the outcome of the vote for the Advisory Compensation Proposal, whereas an abstention will have the same effect as a vote “AGAINST” the Advisory Compensation Proposal.

Approval of the Diamond S Adjournment Proposal requires the affirmative vote of the holders of a majority of the shares of Diamond S common stock represented in person (via the virtual meeting website) or by proxy at the Diamond S special meeting and entitled to vote on the proposal at the Diamond S special meeting.

UNAUDITED PRO FORMA CONDENSED COMBINED FINANCIAL INFORMATION

The following unaudited pro forma condensed combined financial information of the combined company is presented to illustrate the proposed combination of INSW and Diamond S.

On March 30, 2021, INSW and the Merger Sub entered into a merger agreement with Diamond S, pursuant to which Merger Sub will merge with and into Diamond S, and Diamond S will continue as the surviving corporation as a wholly-owned subsidiary of INSW. Upon the closing of the merger, the shareholders of Diamond S will receive consideration in the form of INSW common stock (the “Transaction”).

The unaudited pro forma condensed combined balance sheet as of March 31, 2021 and unaudited pro forma condensed combined statement of operations for the year ended December 31, 2020 and for the three months ended March 31, 2021 are based upon, derived from, and should be read in conjunction with the following: (i) the historical audited consolidated financial statements of INSW, which are available in INSW’s Annual Report on Form 10-K for the fiscal year ended December 31, 2020, as filed with the SEC on March 12, 2021 and which is incorporated by reference in this joint proxy statement/prospectus, (ii) the historical audited consolidated financial statements of Diamond S, which are available in Diamond S’ Annual Report on Form 10-K for the year ended December 31, 2020, as filed with the SEC on March 16, 2021 and which is incorporated by reference in this joint proxy statement/prospectus, (iii) the historical unaudited consolidated financial statements of INSW, which are available in INSW’s Form 10-Q for the quarter ended March 31, 2021, as filed with the SEC on May 6, 2021 and which is incorporated by reference in this joint proxy statement/prospectus, and (iv) the historical unaudited consolidated financial statements of Diamond S, which are available in Diamond S’ Form 10-Q for the quarter ended March 31, 2021, as filed with the SEC on May 10, 2021 and which is incorporated by reference in this joint proxy statement/prospectus.

The unaudited pro forma condensed combined financial information has been prepared in accordance with Article 11 of Regulation S-X, as amended by the final rule, Release No. 33-10786 “Amendments to Financial Disclosures about Acquired and Disposed Businesses.” Release No. 33-10786 replaced the existing pro forma adjustment criteria with simplified requirements to depict the accounting for the transaction (“Transaction Accounting Adjustments”) and present the reasonably estimable synergies and other transaction effects that have occurred or reasonably expected to occur (“Management’s Adjustments”). The combined company has elected not to present Management’s Adjustments and will only be presenting Transaction Accounting Adjustments in the unaudited pro forma condensed combined financial information. The unaudited pro forma condensed combined balance sheet gives effect to the combination as if it had been consummated on March 31, 2021 and the unaudited pro forma condensed combined statement of operations gives effect to the combination as if it had been consummated on January 1, 2020.

The unaudited pro forma condensed combined financial information is subject to the assumptions and adjustments described in the accompanying notes. The pro forma adjustments are based on available information and assumptions that the Company’s management believes are reasonable under the circumstances. Actual results may differ materially from the assumptions within the accompanying unaudited pro forma condensed combined financial information.

The combination has been treated as an asset acquisition under the guidelines of Accounting Standard Codification (“ASC”) 805, Business Combinations, and Accounting Standard Update (“ASU”) 2017-01, Business Combinations (Topic 805), whereby all assets acquired and liabilities assumed are recorded at the cost of the acquisition, including transaction costs, on the basis of their relative fair values. For purposes of the pro forma condensed combined financial information, the fair values of Diamond S’ identifiable tangible and intangible assets acquired and liabilities assumed are based on a preliminary estimate of fair value. Occasionally, upon allocating the cost of the asset acquisition to the individual assets acquired and liabilities assumed based on their relative fair values under ASC 805, an acquiring entity may determine that the total cost of the acquisition may be less than the fair value of the identifiable net assets acquired. In this case the acquirer shall reassess whether it has correctly identified all of the assets acquired and all of the liabilities assumed and shall recognize any additional assets or liabilities that are identified in that review. If the fair value of the identifiable net assets still exceeds the cost of the acquisition, the excess of fair value over cost should be allocated on a relative fair value basis to all qualifying assets, which will result in recognizing qualifying assets at less than fair value and recognizing non-qualifying assets and the assumed liabilities

136

TABLE OF CONTENTS

at fair value. Certain current market-based assumptions were used that will be updated in the accounting for the Transaction upon its completion. INSW’s management believes that the estimated fair values utilized for the assets to be acquired and liabilities assumed for purposes of the pro forma condensed combined financial information, are based on reasonable estimates and assumptions. Preliminary fair value estimates may change as additional information becomes available and such changes could be material.

NOTES TO THE UNAUDITED PRO FORMA CONDENSED COMBINED FINANCIAL INFORMATION

1. Description of Transaction

On March 30, 2021, INSW and Merger Sub, a wholly-owned subsidiary of INSW, entered into a merger agreement with Diamond S, pursuant to which Merger Sub will merge with and into Diamond S, and Diamond S will continue as the surviving corporation that will continue its corporate existence as a wholly-owned subsidiary of INSW. As a result of the merger, the combined company is expected to become the second largest publicly traded shipping company, with a combined fleet of 100 vessels, consisting of 61 product carriers and 37 crude tankers with an aggregate carrying capacity of approximately 10.4 million dwt and two Floating Storage and Offloading Service vessels owned in a joint venture. The merger will result in INSW shareholders owning approximately 55.75% of the issued and outstanding common stock of the combined company and Diamond S shareholders owning approximately 44.25% (based on the fully diluted issued and outstanding common stock of each of Diamond S and INSW as of March 30, 2021). The merger is subject to the approval of each of INSW and Diamond S shareholders, and the effectiveness of this registration statement on Form S-4 to register the additional INSW shares of common stock to be issued in the merger as the merger consideration. The merger is expected to close in the third quarter of 2021. Completion of the merger is also subject to the execution of certain definitive documents, customary closing conditions and regulatory approvals.

Pursuant to the Merger Agreement, the shareholders of Diamond S will receive at the time the Merger is completed an estimated 22,683,532 INSW shares as the merger consideration, which gives Diamond S shareholders the right to receive 0.55375 shares in INSW common stock for each share of Diamond S common stock issued and outstanding immediately prior to the effective time (based on the number of fully diluted Diamond S shares outstanding as of June 1, 2021). Immediately following the Closing of the merger, the estimated 22,683,532 new shares to be issued as the merger consideration will represent approximately 44.25% of the outstanding shares of the Combined Company on a pro forma basis. Prior to the effective time, INSW is permitted to pay a special dividend to its shareholders in an aggregate amount equal to $31.5 million. Payment of the special dividend will not result in a change to the base exchange ratio. The base exchange ratio is subject to an upward adjustment as further described in the merger agreement, to the extent that INSW sells any interest in the FSO Joint Venture prior to the effective time and pays a further special dividend to INSW shareholders from the proceeds of any such sale (up to a maximum of $25 million). The merger agreement provides that, at the effective time, the Diamond S restricted stock units (“RSU”) and restricted stock (“RS”) that are not vested and do not vest at the effective time will be assumed by INSW and will automatically convert into restricted stock units or restricted shares with respect to INSW common stock, on the same general terms and conditions under the applicable Diamond S plans and award agreements in effect immediately prior to the effective time, after giving effect to the exchange ratio and appropriate adjustments to reflect the consummation of the merger.

The merger values the entire issued and outstanding common stock of Diamond S, including RSUs and RS, at approximately $460.0 million based on a closing share price of $20.28 on June 1, 2021 (the latest practicable date used for preparation of the pro forma condensed combined financial information). Except as set forth above in connection with a sale of the FSO Joint Venture, the base exchange ratio will not change and therefore the value of the merger consideration received by shareholders of Diamond S will ultimately be based on the closing price of INSW common stock on the closing date of the merger, and could materially change.

INSW common stock is currently listed for trading on the NYSE under the trading symbol “INSW,” and Diamond S common stock is currently listed for trading on NYSE under the trading symbol “DSSI.” Following the closing of the merger, INSW common stock will continue to be listed on the NYSE and Diamond S common shares will be delisted from NYSE.

2. Accounting Policies

During the preparation of this unaudited pro forma condensed combined financial information, management of INSW has performed a preliminary review and comparison of INSW’s U.S. GAAP accounting policies with those of Diamond S. For purposes of preparing the unaudited pro forma condensed

141

TABLE OF CONTENTS

combined financial information, both INSW’s and Diamond S’ historical audited consolidated financial statements were prepared under U.S. GAAP. The only differences in the application of U.S. GAAP are noted in 4.A and 5.A below. Adjustments have been made to Diamond S historical financial statements to conform its accounting policies to those adopted by INSW. The resulting pro forma condensed combined financial information has not been audited.

Following the consummation of the combination, management of the combined company will conduct a final review of Diamond S’ accounting policies in an effort to determine if further differences in accounting policies are identified that require further adjustment or reclassification of Diamond S’ statement of operations or reclassification of assets or liabilities to conform to INSW’s accounting policies and classifications, as required by acquisition accounting rules. As a result of that review, management may identify differences that, when conformed, could have a material impact on the unaudited pro forma condensed combined financial information as presented herein.

3. Accounting for the Combination

Following the guidelines of ASC 805 and ASU 2017-01, the combination is accounted for identifying INSW as the accounting acquirer. The factors that were considered in determining that INSW should be treated as the accounting acquirer in the Transaction were the relative voting rights in the combined company and the composition of senior management and board of directors of the combined company. With respect to the relative voting rights in the combined company, after the completion of the merger, the current INSW shareholders and Diamond S shareholders will own approximately 55.75% and 44.25% of the combined company, respectively. In addition, following the Transaction, the senior management of INSW will remain in their current roles and lead the combined company and the board of directors of the combined company will be comprised of seven representatives designated by the board of directors of INSW and three representatives designated by the board of directors of Diamond S.

Based on the terms of the merger agreement, the combination was determined to not meet the requirements of a business combination under ASU 2017-01. The combination consists of acquiring vessels and associated assets and liabilities, which are concentrated in a group of similar identifiable assets, and therefore not considered a business. As of March 31, 2021, approximately 93% of Diamond S’ total assets acquired and liabilities assumed, exclusive of cash, were comprised of similar vessels with similar risk characteristics. As a result, the Transaction is expected to be accounted for as an asset acquisition, which values the acquired assets and liabilities at the cost of the acquisition, including transaction costs, on the basis of their relative fair values.

The following represents the preliminary merger consideration of the Transaction:

(Dollars in thousands, except per share data)	Amounts
Diamond S issued and outstanding shares as of March 31, 2021			40,596,182	(a)
Post March 2021 issuance of Diamond S RS and vesting of RSUs, net of forfeitures			14,489	(b)
Estimated Diamond S unvested RSUs at closing date			352,817	(b)
Estimated Diamond S outstanding shares pro forma for closing date			40,963,488
Exchange ratio			0.55375
INSW common stock to be issued to Diamond S shareholders			22,683,532
Closing price per share on June 1, 2021		$	20.28
Consideration transferred		$	460,022
Consideration transferred not related to net asset value acquired		$	30,500	(c)
Consideration transferred related to net asset value acquired		$	429,522	(d)

(a)

Includes 621,822 issued and outstanding restricted shares that are unvested as of March 31, 2021. Subsequent to March 31, 2021, a total of 208,034 restricted shares vested, 2,140 were forfeited and 15,902 restricted shares were granted to members of Diamond S’ board of directors.

(b)

Diamond S granted RSUs and RS to certain executives, employees, and members of their board of

142

TABLE OF CONTENTS

directors. As noted in Note 1 above, the merger agreement provides that the unvested Diamond S restricted stock units and restricted stock that are outstanding at the effective time will be assumed by INSW and replaced with restricted stock units or restricted shares with respect to INSW common stock, after giving effect to the exchange ratio and appropriate adjustments to reflect the consummation of the merger. However, for purposes of the pro forma condensed combined financial information, it is assumed that these RSUs and RS totaling 352,817 and 427,550, respectively, will vest and convert into common shares immediately prior to the effective time. Accordingly, these have been included as part of the estimated Closing Date share count. 274,724 out of the 352,817 unvested RSUs are performance based RSUs, which are estimated based on a payout of 100% for purposes of the pro forma condensed combined financial information.

(c)

ASC 805 requires an evaluation of all consideration transferred by the acquirer to identify the inclusion of any payments that might be related to goods and services that are separate from the combination. Pursuant to the merger agreement, Diamond S' management services agreements with CSMC will be terminated, with the vessels under management by CSMC expected to be re-delivered to the combined company during the remainder of 2021. The estimated termination fee to CSMC is approximately $30.5 million. As INSW is the recipient of the future economic benefits of such restructuring activities, such termination fee is deemed to be a cost incurred by the acquiree on behalf of the acquirer and is considered as part of the consideration transferred that is not related to the fair value of the acquired net asset. As a result, consideration transferred allocated to net asset value acquired is reduced by such amount.

(d)

Includes $25.1 million consideration paid for 51% of the net assets of a joint venture, as discussed in 4.B(9) below.

The pro forma condensed combined financial information reflects the following fair values of tangible and intangible assets acquired and liabilities assumed based on management’s preliminary valuation as of March 31, 2021. The final valuation at closing of the merger may result in different fair values from that presented in the pro forma condensed combined balance sheet:

(Dollars in thousands)	Book Value			Transaction Accounting and Fair Value Adjustments				Fair Value
Vessels, deferred drydock expenditures and other property, net		$	1,707,421		$	(398,571)	(a)		$	1,308,850
Cash			75,824			(44,304)	(b)			31,520
Other current assets			79,373			(1,714)	(b)			77,659
Advances to Norient pool			8,001							8,001
Time charter contracts acquired, net			1,633			5,933	(c)			7,566
Other noncurrent assets			4,640							4,640
Accounts payable, accrued expenses and other current liabilities			(32,261)							(32,261)
Current and noncurrent debt			(645,983)			(11,636)	(d)			(657,619)
Derivative liabilities			(510)							(510)
Noncontrolling interests			(35,586)			11,429	(e)			(24,157)
Net asset value acquired		$	1,162,552		$	(438,863)			$	723,689
Consideration transferred									$	429,522
Excess of net asset value acquired over consideration transferred									$	294,167

(a)

The carrying value of the vessels acquired are adjusted to fair value in accordance with ASC 820, Fair Value Measurement, using the latest valuations obtained from third-party vessel appraisals as of

143

TABLE OF CONTENTS

December 31, 2020. Other property consisting of software and office furniture and equipment with a carrying value of $0.3 million at March 31, 2021, are assumed to have a fair value of zero for the purposes of this calculation.

(b)

Represents transaction accounting adjustments to cash and cash equivalents, voyage receivables, inventories and prepaid expenses and other current assets as discussed below in 4.B.

(c)

The carrying value of the above-market time charter contracts acquired are revalued to their estimated fair value as of March 31, 2021, taking into consideration the differential between the stated time charter rates and the contracts’ fair value at the time of the acquisition.

(d)

Unamortized deferred financing costs were eliminated as part of the fair value measurement of debt assumed.

(e)

The carrying value of the noncontrolling interest acquired is revalued based on its proportionate share of the fair value of its net assets as discussed below in 4.B.(9).

For purposes of the pro forma condensed combined financial information, the fair value of Diamond S’ identifiable tangible and intangible assets acquired and liabilities assumed are based on a preliminary estimate of fair value and such fair value estimate is in excess of the consideration amount. INSW’s management has reassessed whether INSW correctly identified all of the assets acquired and all of the liabilities assumed and determined that such fair value estimate remains in excess of the consideration amount. As the combination is accounted for as an asset acquisition, such excess of the fair value of net asset value acquired over consideration transferred is allocated on a relative fair value basis to all qualifying assets. The calculation of such excess of the fair value of net asset value acquired over consideration transferred will ultimately be based on the Closing Date share price of INSW’s common stock, which could materially change the calculation of the excess of the net asset value acquired over consideration transferred.

The fair value of assets acquired and liabilities assumed will be determined in accordance with ASC 820. As of March 31, 2021, approximately 93% of Diamond S’ total assets acquired and liabilities assumed, exclusive of cash, were comprised of vessels. Upon closing of the merger, the acquired vessel fair values which will be based on their then estimated market values obtained from third-party vessel appraisals, will be adjusted by the estimated transaction costs incurred directly by INSW, which mainly consist of legal, advisory and other professional fees, and reduced by an allocation of the excess of the net asset value acquired over consideration transferred, because the combination is expected to be accounted for as an asset acquisition. The following table provides sensitivities to changes in the fair value of the vessels to be acquired.

(Dollars in thousands)	Valuation			Excess of the fair value of net asset value acquired over consideration transferred			Recognized cost of vessels acquired			Adjustment to depreciation for the year ended December 31, 2020			Adjustment to depreciation for the three months ended March 31, 2021

Decrease of 5%			1,243,408			228,725			1,025,601			(57,431)			(14,074)

For purposes of the pro forma information, the closing stock price of INSW on June 1, 2021 (the latest practicable date used for preparation of the pro forma condensed combined financial information) of $20.28 has been used and compared with net asset acquired as of March 31, 2021, which we have estimated to be $723.7 million. The following table provides sensitivities to changes in the merger consideration due to changes in INSW’s share price on the closing date.

Decrease of 20%			16.22			337,518			386,171			(63,325)			(15,548)

Furthermore, as of March 31, 2021, 95% of Diamond S’ total liabilities consisted of secured indebtedness. The fair value of such arrangements will be determined using the income approach, which will take into consideration the future cash flows that a market participant would expect to receive from holding the liability as an asset. In applying this approach, an estimate will be made for the effective cost of financing that could be obtained in the market at or near the closing date of the merger. This estimate will consider the terms of recently executed credit facilities in addition to INSW’s assessment of prevailing market conditions for financing arrangements under similar terms, conditions and Diamond S’ creditworthiness.

4. Unaudited Pro Forma Condensed Combined Balance Sheet Adjustments as of March 31, 2021

Conforming Accounting Policies

While both INSW and Diamond S prepared historical financial statements in accordance with U.S. GAAP, INSW has adopted ASC 842, Leases, and ASC 326, Financial Instruments — Credit Losses, for the reporting period commencing January 1, 2019 and January 1, 2020, respectively. As an emerging growth company, Diamond S has not adopted ASC 842 or ASC 326.

For a voyage charter that contains a lease component, the Company recognizes revenue and expenses based on a lease commencement-to-discharge basis and the lease commencement date is the latter of discharge of the previous cargo or voyage charter contract signing. For voyage charters that do not have a lease component, the Company recognizes revenue and expenses based on a load-to-discharge basis. Diamond S recognizes revenue and expenses based on a load-to-discharge basis for all voyage charters. In addition, for voyage charters that contain a lease component, the Company expenses fuel costs as incurred whereas Diamond S defers fuel costs incurred prior to the commencement of the voyage. Transaction accounting adjustments have been made to reflect the net changes in the amount of voyage charter revenues and voyage expenses during the year ended December 31, 2020 and during the three months ended March 31, 2021 and the changes to the balances of voyage receivables and prepaid expenses and other current assets as of March 31, 2021. In relation to the lease for Diamond S’ headquarters office space, adjustments have been made to recognize operating lease right-of-use assets and corresponding current and long-term operating lease liabilities associated with the office lease.

The effect of the adoption of ASC 326 was determined to be insignificant for purposes of the pro forma condensed combined financial information as Diamond S’ voyage receivables are operating lease receivables due from charterers, which are not in the scope of ASC 326.

In addition, Diamond S capitalizes lube oil inventory when purchased and expenses the inventory as it is consumed. INSW has an accounting policy to expense lube oil inventory when purchased. Transaction accounting adjustments have been made to reflect the net changes in the amount of vessel expenses during the year ended December 31, 2020 and during the three months ended March 31, 2021 and eliminate the balance of lube oil inventory from the March 31, 2021 pro forma condensed combined balance sheet.

TABLE OF CONTENTS

Pro Forma Adjustments

(1) Cash and cash equivalents

The decrease in cash and cash equivalents of $82.7 million is composed of the following:

(Dollars in thousands)	Amounts
Special cash dividend		$	(31,500)	(a)
Transaction costs paid by cash			(17,079)	(b)
Management services termination fee			(30,500)	(c)
Other costs related to the merger			(3,666)	(d)
		$	(82,745)

(a)

Immediately prior to the closing of the Transaction, existing INSW shareholders will receive a special cash dividend in an aggregate amount equal to $31.5 million.

(b)

Total transaction costs are estimated to be approximately $25.9 million, which includes $10.9 million of INSW’s transaction costs directly related to the asset acquisition as discussed in 4.B.(4) below and $15.0 million of similar costs incurred by Diamond S which includes debt consent fees as discussed in 4.B.(7) below. The actual transaction costs incurred could differ materially from this estimate. Approximately $8.8 million of such costs are included in the accounts payable, accrued expenses and other current liabilities line of the historical March 31, 2021 balance sheets of INSW and Diamond S, respectively. Accordingly, only the balance of $17.1 million is reflected as a pro forma adjustment to the historical March 31, 2021 cash balance.

(c)

The estimated termination fee to CSMC of approximately $30.5 million is included in the pro forma condensed combined balance sheet, and condensed combined statement of operations as a nonrecurring cost.

(d)

Represents the insurance premium for the tail policy to Diamond S’ current directors and officers liability insurance policy to cover potential claims arising from facts or events occurring at or prior to the effective date (the “D&O Insurance”). Pursuant to the merger agreement, such policy shall be maintained by the combined company for an aggregate period of six years from the closing date.

(2) Voyage receivables and prepaid expenses and other current assets

The increase in voyage receivables of $2.9 million and the decrease in prepaid expenses and other current assets of $1.8 million represents adjustments made to reflect the application of ASC 842 to Diamond S’ voyage charters as discussed above in 4.A.

In addition, prepaid expenses and other current assets includes a $3.7 million D&O Insurance premium as discussed above in (1).

(3) Inventories

The decrease in inventory of $6.5 million represents adjustment made to Diamond S’ historical March 31, 2021 balance sheet to eliminate the lube oil inventory balance as discussed above in 4.A.

(4) Vessels and other property and deferred drydock expenditures

The $1.0 billion balance of acquired vessel values as of March 31, 2021, is comprised of the estimated fair value of the vessels of $1.3 billion, which is based on the market values obtained from third-party vessel appraisals as of December 31, 2020, the estimated transaction costs to be incurred directly by INSW of $10.9 million, which mainly consist of legal, advisory and other professional fees, reduced by a $294.2 million allocation of the excess of the net asset value acquired over consideration transferred to the fair value of vessels acquired because the combination is expected to be accounted for as an asset acquisition. Deferred drydock expenditures are taken into consideration in the vessel appraisals obtained to determine the market values of the vessels acquired and are therefore eliminated for purposes of the pro forma condensed combined financial information.

TABLE OF CONTENTS

(5) Operating lease right-of-use assets and liabilities

The operating lease right-of-use asset of $5.5 million and the corresponding current and long-term operating lease liabilities of $0.8 million and $4.7 million, respectively, relate to Diamond S’ headquarters office lease expiring July 2026, and have been reflected in the pro forma condensed combined balance sheet in order to reflect the application of ASC 842.

(6) Time charter contracts acquired, net

In accordance with ASC 820, the above market time charter contracts are recorded at estimated fair value at the time of acquisition. For purposes of the unaudited pro forma condensed combined financial information, the Company estimates $7.6 million to be the value of above market time charter contracts (assets), which were in existence as of March 31, 2021, at the Closing Date. The fair value estimate takes into consideration future cash flows under the time charters compared to estimated future market-based charter rates, using a discounted cash flow model.

(7) Long-term debt

All unamortized deferred financing costs associated with existing financing arrangements of Diamond S of $11.6 million were eliminated as part of the fair value measurement. The preliminary cost allocation estimates the fair value of Diamond S’ secured borrowings, all of which will be assumed as part of the merger. Fair value was measured using the income approach, which takes into account the future cash flows that a market participant would expect to receive from holding the liability as an asset. The carrying amount of the variable rate borrowings under the secured debt facilities as of March 31, 2021 approximates the fair value estimated based on current market rates and an appropriate credit spread. The credit spread is estimated as the margin over LIBOR in Diamond S’ recently entered secured debt facilities, which varies from 2.5% to 3.25%, and represents INSW management’s best estimate of such credit spreads. Accordingly, no fair value adjustment has yet been made for purposes of the pro forma condensed combined balance sheet.

In connection with and as a condition to the consummation of the merger, lenders under Diamond S’ existing credit facilities, have agreed, among other things, to consent to the merger and waive any event of default that would arise as a result of the merger. Lenders under Diamond S’ $360 Million Facility and $525 Million Facility also agreed to enter into amended and restated credit agreements to amend the terms of such credit facilities to more closely mirror the representations, warranties and covenants of INSW’s credit facilities and to include INSW as a credit party. In addition, INSW agreed to provide a guaranty of Diamond S’ obligations under the amended and restated debt agreements. The amended and restated credit agreements were entered into on May 27, 2021. The non-refundable consent fees due and payable by Diamond S on the merger effective date along with legal costs associated with obtaining these consents are estimated to approximate $2.6 million. The consent fees and legal costs associated with obtaining the consents, which are included in the pro forma condensed combined statement of operations are nonrecurring costs.

(8) Equity

The following increases/(decreases) have been made to total equity before noncontrolling interest:

(Dollars in thousands)	Capital			Accumulated Deficit			Accumulated Other Comprehensive Loss			Total Equity
Pro forma condensed combined balance sheet adjustments:
Cost of net assets acquired		$	429,522		$	—		$	—		$	429,522

TABLE OF CONTENTS

(9) Noncontrolling Interest

Diamond S owns two 2016-built Suezmaxes through a joint venture, NT Suez Holdco LLC (“NT Suez”), which is owned 51% by Diamond S and 49% by WLR/TRF Shipping S.a.r.l (“WLR/TRF”). WLR/TRF is indirectly owned by funds managed or jointly managed by WL Ross & Co, LLC (“WLR”), including WLR Recovery Fund V DSS AIV, L.P. and WLR V Parallel ESC, L.P., which are also shareholders of Diamond S. WLR is a fund manager that manages Diamond S’ largest shareholders. Management has determined that NT Suez qualifies as a VIE, and, when aggregating the variable interests held by the related parties (i.e., Diamond S and WLR/TRF), Diamond S is the primary beneficiary as it has the ability to direct the activities that most significantly impact NT Suez’s economic performance. Accordingly, Diamond S consolidates NT Suez. The carrying value of the noncontrolling interest acquired is revalued based on its proportionate share of the fair value of its net assets as of March 31, 2021:

(Dollars in thousands)	Fair Value
Vessels		$	89,750
Time charter contracts			5,873
Debt			(46,323)
Net amount of VIE's identifiable assets and liabilities		$	49,300
Non controlling interest %			49%
Fair value of non controlling interest		$	24,157

5. Unaudited Pro Forma Condensed Combined Statement of Operations Adjustments for the Year Ended December 31, 2020 and for the three months ended March 31, 2021

Conforming Accounting Policies

The effect of adoption of ASC 326 was determined to be insignificant for purposes of the pro forma condensed combined financial information as Diamond S’ voyage receivables are operating lease receivables due from charterers, which are not in the scope of ASC 326.

148

TABLE OF CONTENTS

Pro Forma Adjustments

(1) Time and bareboat charter revenues

For the year ended December 31, 2020, time and bareboat charter revenues have been decreased by $4.1 million to eliminate Diamond S’ historical amortization of time charter contracts acquired of $2.8 million and amortize the revalued asset for time charter contracts acquired of $6.9 million, as noted above in “4.B.(5) Time charter contracts acquired, net,” amortized over the remaining terms of the applicable time charter contracts.

For the three months ended March 31, 2021, time and bareboat charter revenues have been decreased by $1.0 million to eliminate Diamond S’ historical amortization of time charter contracts acquired of $0.6 million and amortize the revalued asset for time charter contracts acquired of $1.6 million.

(2) Voyage charter revenues and voyage expenses

For the year ended December 31, 2020, the decrease in voyage charter revenues of $5.3 million, and the decrease in voyage expenses of $2.2 million represent the net adjustments made to conform Diamond S’ revenue and expense recognition policy for voyage charters to that of the Company as discussed above in 5.A.

For the three months ended March 31, 2021, such adjustments resulted in an increase of $0.9 million in voyage charter revenues and voyage expenses, respectively.

(3) Vessel expenses

The increase in vessel expenses of $0.5 million for the year ended December 31, 2020 and the decrease in vessel expenses of $0.1 million for the three months ended March 31, 2021 represent the net adjustments made to conform Diamond S’ lube oil expense recognition policy to that of the Company as discussed above in 5.A.

(4) Depreciation and amortization

For the year ended December 31, 2020, depreciation and amortization expense has been reduced by $57.4 million as a result of the fair value adjustment to the carrying value of the vessels acquired as of January 1, 2020 as part of the preliminary accounting for the asset acquisition. Consistent with INSW’s and Diamond S’ accounting policies, depreciation is calculated on a straight-line basis over the anticipated remaining useful life of 25 years from each vessel’s date of delivery down to the vessel’s estimated salvage value, using the vessel’s lightweight tonnage multiplied by an estimated scrap steel price of $300 per ton.

For the three months ended March 31, 2021, such adjustment amounted to $14.1 million.

(5) General and administrative

Amortization of the D&O Insurance policy as discussed in Note 4.B.(1) above amounted to $0.6 million and $0.2 million, respectively, for the year ended December 31, 2020 and for the three months ended March 31, 2021.

For purposes of the pro forma condensed combined financial information, the $4.9 million transaction costs recorded in general and administrative line of Diamond S’ historical statement of operations for the three months ended March 31, 2021 were eliminated in the pro forma condensed combined statement of operations for the three months ended March 31, 2021 as such costs were included in the transaction and other costs related to merger line of the pro forma condensed combined statement of operations for the year ended December 31, 2020.

6. Net Income/(Loss) Per Share

The unaudited pro forma condensed combined basic and diluted earnings per share calculations are based on the aggregate basic and diluted weighted average shares of the combined company. The pro forma basic and diluted weighted average shares outstanding are determined using the exchange ratio stated in the merger agreement of 0.55375 share of INSW common stock per Diamond S common share issued and outstanding immediately prior to the effective time.

The weighted average numbers of common shares outstanding were calculated as follows:

	For the Year ended December 31, 2020		For the Three Months ended March 31, 2021
Weighted average number of common shares – historical		28,372,375		28,023,815

MATERIAL U.S. FEDERAL INCOME TAX CONSEQUENCES OF THE MERGER

The following is a general discussion of material U.S. federal income tax consequences of the merger to U.S. Holders (as defined below) of Diamond S common stock. This discussion applies only to U.S. Holders who hold their Diamond S common stock as “capital assets” within the meaning of Section 1221 of the Code (generally, property held for investment). This discussion is based on current provisions of the Code, the Treasury Regulations promulgated thereunder, judicial interpretations thereof and administrative authorities, rulings and decisions, each as in effect as of the date hereof, all of which are subject to change or differing interpretations, possibly with retroactive effect, and any such change or differing interpretation could affect the accuracy of the statements and conclusions set forth herein. This discussion assumes that the merger will be completed in accordance with the merger agreement and as further described herein. This discussion does not address any considerations under U.S. federal tax laws other than those pertaining to the income tax, nor does it address any considerations with respect to the Medicare tax on net investment income or any state, local or non-U.S. tax laws. Furthermore, it does not address any tax consequences to holders who are not U.S. Holders.

For purposes of this discussion, the term “U.S. Holder” means a beneficial owner of Diamond S common stock that is, for U.S. federal income tax purposes:

•

an individual who is a citizen or resident of the United States;

•

a corporation (or other entity taxable as a corporation for U.S. federal income tax purposes) created or organized in or under the laws of the United States, any state thereof or the District of Columbia;

•

an estate the income of which is subject to U.S. federal income tax regardless of its source; or

•

a trust (i) the administration of which is subject to the primary supervision of a U.S. court and which has one or more United States persons who have the authority to control all substantial decisions of the trust or (ii) which has made a valid election under applicable U.S. Treasury regulations to be treated as a United States person.

If an entity or arrangement treated as a partnership for U.S. federal income tax purposes holds Diamond S common stock, the tax treatment of a partner in such partnership generally will depend on the status of the partner and the activities of the partnership. An entity or arrangement treated as a partnership for U.S. federal income tax purposes and any partners in such partnership should consult their own tax advisors regarding the tax consequences of the merger to them.

This discussion is for general information only and does not purport to address all aspects of U.S. federal income taxation that may be relevant to particular U.S. Holders of Diamond S common stock in light of their particular facts and circumstances and does not apply to U.S. Holders of Diamond S common stock that are subject to special rules under the U.S. federal income tax laws (including, for example, banks or other financial institutions, dealers in stocks and securities, commodities or currencies, traders in securities that elect to apply a mark-to-market method of accounting, insurance companies, mutual funds, tax-exempt entities, entities or arrangements treated as partnerships for U.S. federal income tax purposes or other flow-through entities (and investors therein), subchapter S corporations (and investors therein), retirement plans, individual retirement accounts or other tax-deferred accounts, real estate investment trusts, regulated investment companies, persons liable for the alternative minimum tax, persons subject to special timing rules under Section 451(b) of the Code, certain former citizens or former long-term residents of the United States, U.S. Holders having a functional currency other than the U.S. dollar, and U.S. Holders who hold their Diamond S common stock as part of a hedge, straddle, constructive sale, conversion transaction or other integrated transaction). In addition, this discussion does not address the consequences of the merger to U.S. Holders of Diamond S common stock who actually or constructively own 5% or more by vote or value of Diamond S common stock (immediately prior to the merger) or of INSW common stock (immediately after the merger), or U.S. Holders who acquired their Diamond S common stock through the exercise of an employee option or otherwise as compensation or through a tax-qualified retirement plan.

HOLDERS OF DIAMOND S COMMON STOCK SHOULD CONSULT THEIR OWN TAX ADVISORS WITH RESPECT TO THE PARTICULAR TAX CONSEQUENCES TO THEM OF THE MERGER, INCLUDING THE APPLICABILITY AND EFFECT OF ANY U.S. FEDERAL, U.S. STATE OR LOCAL OR NON-U.S. TAX LAWS OR ANY APPLICABLE TAX TREATY.

TABLE OF CONTENTS

Qualification of the Merger for the Intended Tax Treatment

It is intended that, for U.S. federal income tax purposes, (i) the merger qualifies as a “reorganization” under Section 368(a) of the Code and (ii) the merger not result in the recognition of gain under Section 367(a)(1) of the Code (other than, in certain circumstances, a transfer by a holder of Diamond S common stock that is a United States person (as defined in Section 7701 of the Code) and that holds 5% or more by vote or by value (within the meaning of Treasury Regulations Section 1.367(a)-3(b)(1)(i)) of the INSW common stock outstanding immediately following the merger).

The completion of the merger is not conditioned upon the receipt of an opinion of counsel to the effect that the merger qualifies for the Intended Tax Treatment. In addition, neither Diamond S nor INSW intends to request a ruling from the IRS regarding the U.S. federal income tax consequences of the merger. Accordingly, no assurance can be given that the IRS will not challenge the Intended Tax Treatment or that a court would not sustain such a challenge.

U.S. Federal Income Tax Consequences of the Merger to U.S. Holders of Diamond S Common Stock if the Merger Does not Qualify for the Intended Tax Treatment

If the merger fails to qualify for the Intended Tax Treatment, a U.S. Holder of Diamond S common stock would generally recognize gain or loss in an amount equal to the difference, if any, between (i) the fair market value of the INSW common stock and cash, if any, received by such holder in the merger, and (ii) such holder’s tax basis in the Diamond S common stock surrendered. Gain or loss must be calculated separately for each block of Diamond S common stock exchanged by such U.S. Holder if such blocks were acquired at different times or at different prices. Any gain or loss so recognized with respect to a particular block of Diamond S common stock generally would be long-term capital gain or loss if the U.S. Holder’s holding period in such block of Diamond S common stock exceeds one year at the Effective Time. Long-term capital gain of non-corporate U.S. Holders (including individuals) currently is eligible for preferential U.S. federal income tax rates. The deductibility of capital losses is subject to limitations. If the merger fails to qualify for the Intended Tax Treatment, a U.S. Holder’s holding period in INSW common stock received in the merger would begin on the day following the merger.

U.S. Federal Income Tax Consequences of the Merger to U.S. Holders of Diamond S Common Stock if the Merger Qualifies for the Intended Tax Treatment

If the merger qualifies for the Intended Tax Treatment, the U.S. federal income tax consequences of the merger to U.S. Holders of Diamond S common stock generally should be as follows:

•

a U.S. Holder of Diamond S common stock who exchanges Diamond S common stock for INSW common stock pursuant to the merger generally should not recognize gain or loss, except with respect to cash received in lieu of a fractional share of INSW common stock (as discussed below);

•

a U.S. Holder of Diamond S common stock should have an aggregate tax basis in the INSW common stock received in the merger (including any fractional shares deemed received and redeemed for cash as described below) equal to the aggregate adjusted tax basis in the Diamond S common stock surrendered in the merger; and

•

a U.S. Holder of Diamond S common stock should have a holding period for the INSW common stock received in the merger (including any fractional shares deemed received and redeemed for cash as described below) that includes the holding period of the Diamond S common stock surrendered in the merger.

If a U.S. Holder acquired different blocks of Diamond S common stock at different times or at different prices, the INSW common stock such holder receives will be allocated pro rata to each block of Diamond S common stock exchanged for such INSW common stock, and the basis and holding period of each block of INSW common stock received will be determined on a block-for-block basis depending on the basis and holding period of the blocks of Diamond S common stock exchanged for such INSW common stock.

Each U.S. Holder of Diamond S common stock who receives cash in lieu of a fractional share of INSW common stock generally will be treated as having received such fractional share of INSW common

152

TABLE OF CONTENTS

stock pursuant to the merger and then as having sold such fractional share for cash. Any such holder will recognize gain or loss equal to the difference between the amount of cash received and the basis in the holder’s fractional share of INSW common stock (as set forth above). Such gain or loss generally will be long-term capital gain or loss if, as of the Effective Time, the holding period for such fractional share of INSW common stock (as described above) exceeds one year. Long-term capital gain of non-corporate U.S. Holders (including individuals) currently is eligible for preferential U.S. federal income tax rates. The deductibility of capital losses is subject to limitations.

Notwithstanding the above, although Diamond S does not believe it is currently a “passive foreign investment company” within the meaning of Section 1297 of the Code for U.S. federal income tax purposes, if Diamond S is now or previously was for any year a PFIC, the merger may in certain circumstances be taxable to U.S. Holders of Diamond S common stock who owned equity interests in Diamond S while Diamond S was a PFIC even if the merger qualifies for the Intended Tax Treatment. U.S. Holders of Diamond S common stock who believe they may have held equity interests of Diamond S while it was a PFIC are urged to consult with their own tax advisors regarding the consequences to them of the merger.

Information Reporting and Backup Withholding

In addition, a U.S. Holder generally would be subject to information reporting and would, under certain circumstances, be subject to backup withholding (currently at a rate of 24%) with respect to the INSW common stock and cash received in the merger, unless such holder properly establishes an exemption or provides, on a properly completed IRS Form W-9, its correct tax identification number and otherwise complies with the applicable requirements of the backup withholding rules. Backup withholding is not an additional tax. Any amounts withheld under the backup withholding rules can be refunded or credited against the holder’s U.S. federal income tax liability, if any, provided that an appropriate claim is timely filed with the IRS.

TABLE OF CONTENTS

DESCRIPTION OF INSW CAPITAL STOCK

The following description of the INSW common stock is not complete and may not contain all the information you should consider before investing in INSW common stock. This description is a summary of certain provisions contained in, and is qualified in its entirety by reference to, INSW’s amended and restated articles of incorporation and INSW’s amended and restated by-laws.

Authorized Capitalization

INSW authorized capital stock consists of (a) 100,000,000 authorized shares of common stock, no par value, and (b) 10,000,000 shares of preferred stock, no par value (the “preferred stock”).

As of June 1, 2021, there were 28,087,011 shares of INSW common stock outstanding and no shares of preferred stock outstanding. No shares of INSW common stock were held in treasury by INSW.

INSW Common Stock

The holders of INSW common stock are entitled to dividends as the INSW Board may declare from time to time from legally available funds, based on the number of shares of INSW common stock then held of record by such holder, subject to the preferential rights of the holders of any shares of preferred stock that INSW may issue in the future. The holders of INSW common stock are entitled to one vote per share.

INSW’s amended and restated articles of incorporation do not provide for cumulative voting in the election of directors, which means that the holders of a majority of the outstanding shares of INSW common stock can elect all of the directors standing for election, and the holders of the remaining shares are not able to elect any directors. INSW’s amended and restated by-laws provide that directors will be elected by a majority of the shares voting once a quorum is present.

Upon any voluntary or involuntary liquidation, dissolution or winding up of our affairs, the holders of INSW common stock are entitled to share, on a pro rata basis, all assets remaining after payment to claimants and creditors and subject to prior distribution rights of any shares of preferred stock that INSW may issue in the future. All of the outstanding shares of INSW common stock are fully paid and non-assessable. Holders of INSW common stock have no preemptive rights, conversion rights or other subscription rights as set out in INSW’s amended and restated articles of incorporation, and there are no redemption or sinking fund provisions applicable to INSW common stock. The rights, preferences and privileges of holders of INSW common stock are subject to, and may be impacted by, the rights of the holders of shares of any series of preferred stock that INSW may designate and issue in the future.

As of March 30, 2021, there were approximately 39 holders of record of INSW common stock, including Cede & Co., as nominee for the Depository Trust Company, or DTC.

INSW Preferred Stock

INSW’s amended and restated articles of incorporation authorizes the INSW Board or a committee of the INSW Board to cause preferred stock to be issued in one or more series, without stockholder action. INSW is authorized to issue up to 10,000,000 shares of preferred stock and can determine the number of shares of each series, and the rights, designations, preferences and limitations of each series. INSW may amend its amended and restated articles of incorporation to increase the number of authorized shares of preferred stock in a manner permitted by INSW’s amended and restated articles of incorporation and Marshall Islands law. As of the date of this joint proxy statement/prospectus, there were no preferred shares outstanding.

Anti-Takeover Provisions of INSW’s Amended and Restated Articles of Incorporation, By-Laws and RMI Law

INSW’s amended and restated articles of incorporation and amended and restated by-laws contain a number of provisions relating to corporate governance and to the rights of stockholders. Certain of these provisions may be deemed to have a potential “anti-takeover” effect in that such provisions may delay, defer or prevent a change of control or an unsolicited acquisition proposal that a stockholder might consider favorable, including a proposal that might result in the payment of a premium over the market price for the

154

TABLE OF CONTENTS

shares held by the stockholders. Examples of such provisions in INSW’s amended and restated articles of incorporation and amended and restated by-laws relating to corporate governance and the rights of stockholders, certain of which may be deemed to have a potential “anti-takeover” effect include:

Authorized but Unissued or Undesignated Capital Stock. INSW’s authorized capital stock consists of 100,000,000 authorized shares of INSW common stock and 10,000,000 shares of preferred stock. A large quantity of authorized by unissued shares may deter potential takeover attempts because of the ability of the INSW Board to authorize the issuance (without a shareholder vote) of some or all of these shares to a friendly party, or to the public, which would make it more difficult for a potential acquirer to obtain control of INSW. This possibility may encourage persons seeking to acquire control of INSW to negotiate first with the INSW Board. The authorized but unissued stock may be issued by the INSW Board in one or more transactions. In this regard, INSW’s amended and restated articles of incorporation grants the INSW Board broad power to establish the rights and preferences of authorized by unissued preferred stock. Although INSW’s amended and restated articles of incorporation prohibits the INSW Board, without the affirmative vote of at least a majority of the total voting power of INSW outstanding shares of capital stock entitled to vote on such matters, voting as a class, from issuing any preferred stock for any defensive or anti-takeover purpose, for the purpose of implementing any shareholder rights plan or with features specifically intended to make any attempted acquisition of INSW more difficult or costly, the issuance of shares of preferred stock pursuant to the INSW Board’s authority described above could decrease the amount of earnings and assets available for distributions to holders of INSW common stock and adversely affect the rights and powers, including the voting rights, of such holders and may have the effect of delaying, deferring or preventing a chance of control. The INSW Board does not currently intend to seek stockholder approval prior to any issuance of preferred stock, unless otherwise required by law or INSW’s amended and restated articles of incorporation.

Action by Written Consent. INSW’s amended and restated by-laws and Section 7 of the BCA provide that stockholder action can be taken by written consent in lieu of a meeting if all stockholders entitled to vote on the subject matter unanimously consent.

Special Meeting of Stockholders. INSW’s amended and restated by-laws provide that special meetings of INSW’s stockholders may be called only by the president or vice president of INSW, by resolution of the INSW Board or by holders of not less than 25% of all outstanding shares entitled to vote on the matter for which the meeting is called. INSW’s amended and restated by-laws prohibit the conduct of any business at a special meeting other than as specified in the notice for such meeting.

Advance Notice Procedures. INSW’s amended and restated by-laws establish advance notice procedures with respect to stockholder procedures and the nomination of candidates for election as directors, other than nomination made by or at the directions of the INSW Board. In order for any matter to be “properly brought” before a meeting, a stockholder will have to comply with advance notice requirements to provide INSW with certain information. Generally, to be timely, a stockholder’s notice must be received at INSW’s principal executive offices not less than 60 days or more than 90 days prior to the first anniversary of the date immediately preceding the annual meeting. In the event that the date of the annual meeting is more than 30 days earlier or more than 60 days later than such anniversary date, notice by the stockholder must be received no earlier than 90 days prior to the annual meeting and no later than the later of (i) 60 days prior to the annual meeting or (ii) 10 days following the public announcement of the date of the annual meeting. INSW’s amended and restated by-laws also specify requirements as to the form and content of a stockholder’s notice. These provisions may defer, delay or discourage a potential acquirer from conducting a solicitation of proxies to elect the acquirer’s own slate of directors or otherwise attempting to influence or obtain control from INSW.

Super Majority Approval Requirements. INSW’s amended and restated by-laws provide that the INSW Board, at any regular meeting or special meeting called for such purpose, and INSW stockholders, at any annual meeting or special meeting called for such purpose, may make, alter, amend or repeal INSW’s amended and restated by-laws. However, the INSW Board may not, without the affirmative vote of a majority of the outstanding stock entitled to vote on such matters, alter, amend or repeal certain provisions of INSW’s amended and restated by-laws, including those relating to stockholder meeting quorum requirements, majority election of directors, notification of the nomination for the election of directors, special meetings of the INSW Board, committees of the INSW Board and amendments to the amended and restated by-laws.

TABLE OF CONTENTS

Further, the INSW Board may not, without the affirmative vote of the holders of two-thirds or more of the outstanding stock entitled to vote on such matters, alter, amend or repeal certain other provisions of INSW’s amended and restated by-laws, including those relating to the calling of special meetings by stockholders and stockholder action by written consent.

The BCA provides generally that the affirmative vote of a majority of the outstanding shares then entitled to vote is required to amend a corporation’s articles of incorporation, unless the articles of incorporation requires a greater percentage. INSW’s amended and restated articles of incorporation provides that specified provisions, including those relating to amendment of INSW’s amended and restated articles of incorporation and the procedures by which any action required or permitted to be taken by holders of INSW common stock may be performed, may only be amended or repealed by the affirmative vote of two-thirds of the combined voting power of the outstanding shares of INSW’s capital stock.

The combination of these provisions may make it more difficult for INSW’s existing stockholders to replace the INSW Board as well as for another party to obtain control of INSW by replacing the INSW Board. Because the INSW Board has the power to retain or discharge INSW’s officers, these provisions could also make it more difficult for existing stockholders or another party to effect a change in management.

Limitation of Liability and Indemnification of Officers and Directors

Under the BCA, a Marshall Islands corporation shall have the power to indemnify any person who was or is a party or is threatened to be made a party to or a witness in or is otherwise involved in any threatened, pending or completed action, suit, claim, inquiry or proceeding whether civil, criminal, administrative or investigative (including an action by or in the right of the corporation) and whether formal or informal, by reason of the fact that he or she, or a person for whom he or she is the legal representative, is or was a director or officer of the corporation, or, while a director or officer of the corporation, is or was serving at the request of the corporation as a director, officer, employee, trustee or agent of another corporation, partnership, joint venture, trust, nonprofit or other entity, including service with respect to employee benefit plans, against all liability and loss suffered, and expenses (including attorneys’ fees) actually and reasonably incurred by him or her in connection with such action, suit or proceeding. The corporation shall be required to indemnify or advance expenses to such a person in connection with a proceeding commenced by the person against the corporation only if the commencement of such proceeding was authorized in the specific case by the board of directors or was brought to establish or enforce a right to indemnification under the bylaws, the corporation’s articles of incorporation, any agreement, the laws of the Republic of the Marshall Islands or otherwise.

To the extent that a director or officer of a Marshall Islands corporation has been successful on the merits or otherwise in defense of any action, suit or proceeding referred to in the preceding paragraphs, or in the defense of a claim, issue or matter therein, he or she shall be indemnified against expenses (including attorneys’ fees) actually and reasonably incurred by him or her in connection therewith. Expenses incurred in defending a civil or criminal action, suit or proceeding may be paid in advance of the final disposition of such action, suit or proceeding as authorized by the board of directors in the specific case upon receipt of an undertaking by or on behalf of the director or officer to repay such amount unless it shall ultimately be determined that he or she is entitled to be indemnified by the corporation as authorized in the BCA.

In addition, a Marshall Islands corporation has the power to purchase and maintain insurance on behalf of any person who is or was a director or officer of the corporation or is or was serving at the request of the corporation as a director or officer against any liability asserted against him or her and incurred by him or her in such capacity whether or not the corporation would have the power to indemnify him or her against such liability under the provisions of the BCA. The indemnification provisions of the BCA are not exclusive of any other rights under any bylaw, agreement, vote of stockholders or disinterested directors or otherwise.

INSW’s amended and restated articles of incorporation limits the liability of INSW’s directors to the fullest extent permitted by the BCA and requires that INSW provide them with customary indemnification.

TABLE OF CONTENTS

CERTAIN BENEFICIAL OWNERS OF INSW COMMON STOCK

General

The tables below set forth certain beneficial ownership information with respect to certain individuals and stockholders of INSW as of June 1, 2021. Except as disclosed in the notes to these tables and subject to applicable community property laws, INSW believes that each beneficial owner identified in the table possesses sole voting and investment power over all INSW common stock shown as beneficially owned by the beneficial owner.

Beneficial ownership for the purposes of the following tables is determined in accordance with the rules and regulations of the SEC. Those rules generally provide that a person is the beneficial owner of shares if such person has or shares the power to vote or direct the voting of shares, or to dispose or direct the disposition of shares or has the right to acquire such powers within 60 days. For purposes of calculating each person’s percentage ownership, shares of INSW common stock issuable pursuant to options exercisable within 60 days (including out of the money options) are included as outstanding and beneficially owned for that person, but are not deemed outstanding for the purposes of computing the percentage ownership of any other person. The percentage of beneficial ownership is based on 28,087,011 shares of INSW’s common stock outstanding as of June 1, 2021, and excludes any treasury stock.

Directors and Executive Officers

The table below sets forth information as to each director, director nominee and named executive officer of INSW, and includes the amount and percentage of the INSW common stock of which each director, director nominee, each named executive officer of INSW, and all directors, directors nominees and executive officers as a group, was the “beneficial owner” (as defined in regulations of the SEC) on the record date, all as reported to INSW.

COMPARISON OF THE RIGHTS OF COMBINED COMPANY STOCKHOLDERS
AND DIAMOND S SHAREHOLDERS

Both INSW and Diamond S are incorporated under the laws of the Republic of the Marshall Islands, and, accordingly, the rights of the INSW stockholders and the Diamond S shareholders each are currently governed by the Marshall Islands Business Corporations Act (the “BCA”). INSW will continue to be a Republic of the Marshall Islands corporation following completion of the merger and will be governed by the BCA.

The Diamond S shareholders as of immediately prior to the completion of the merger will, at the effective time, receive INSW common stock. Diamond S’ pre-merger shareholders will hold approximately 44.25%, and INSW’s pre-merger stockholders will hold approximately 55.75%, of the outstanding shares of common stock of the combined company upon the completion of the merger. The rights of the former Diamond S shareholders and the INSW stockholders will thereafter be governed by the BCA and by the combined company’s amended and restated articles of incorporation and the amended and restated by-laws. The rights of the combined company stockholders following the merger are generally consistent with the rights of INSW stockholders prior to the merger, other than with respect to the governance provisions that will be implemented in connection with the merger as described in the section entitled “The Merger Agreement — Combined Company Governance.”

The following description summarizes the material differences between the rights of Diamond S shareholders and the rights of the combined company stockholders, based on the current amended and restated certificate of incorporation and by-laws of Diamond S, the combined company’s amended and restated articles of incorporation, the by-laws of INSW and the BCA. This does not purport to be a complete statement of all those differences, or a complete description of the specific provisions referred to in this summary. The identification of specific differences is not intended to indicate that other equally significant or more significant differences do not exist. Shareholders of Diamond S and stockholders of INSW should read carefully the relevant provisions of the BCA, the INSW articles of incorporation and current by-laws, the Diamond S certificate of incorporation, and the Diamond S by-laws. Copies of the documents referred to in this summary may be obtained as described under the section entitled “Where You Can Find More Information.”

	Rights of Combined Company Stockholders	Rights of Diamond S Shareholders
Authorized Capital Stock	The authorized capital stock of the combined company will consist of 110,000,000 total shares, of which 100,000,000 shares are common stock without par value, and 10,000,000 shares are preferred stock without par value.	The authorized capital stock of Diamond S consists of 110,000,000 registered shares, consisting of 100,000,000 registered common shares, par value $0.001 per share, and 10,000,000 registered preferred shares, par value $0.001 per share.
Preferred Stock	The combined company’s articles of incorporation will provide that the board of directors of the combined company may authorize the issue of one or more series of preferred stock and fix by resolution the voting powers, full or limited, if any, of the shares of such series and the designations, preferences and relative, participating, optional or other special rights, as well as the qualifications, limitations or restrictions of the series.	Diamond S’ amended and restated articles of incorporation provide that the Diamond S Board may authorize the issue of one or more series of preferred shares and fix from time to time before issuance the number of shares to be included in any such series and the designation, powers, preferences and relative, participating, option or other rights, if any, and the qualifications, limitations or restrictions of the series.

The Diamond S by-laws provide that special meetings of shareholders may be called only (a) by (i) the chairman of the Diamond S Board, (ii) the chief executive officer of Diamond S or (iii) the secretary within ten calendar days after receipt by the chairman and the secretary of the written request of the Diamond S Board or holders of more than 10% of the voting power of the outstanding common shares and preferred shares of Diamond S or (b) as specified in a preferred stock designation.

Number and Qualification of Directors	The BCA provides that the board of directors of a Marshall Islands corporation must consist of one or more directors, with the number of directors fixed by or in the manner provided in the corporation’s by-laws, by the shareholders, or by action of the board under the specific provisions of a by-law.
	The combined company’s articles of incorporation will provide that the number of directors must not be less than seven nor more than 11, provided that the number of directors may be changed by an affirmative vote of a majority of the whole board of directors of the combined company at any regular or special meeting of the board of directors of the combined company, provided that the number of directors shall not be reduced by action of the board of directors of the combined company below the number of directors then in office. Directors need not be stockholders of the combined company. There are currently eight directors serving on the INSW Board. No shareholder will have a contractual right to designate a director to the combined company’s board of directors.	Diamond S’ amended and restated articles of incorporation provide that the number of directors will not be fewer than three nor more than 15, subject to the rights, if any, of the holders of any series of preferred shares to elect additional directors, and will be fixed from time to time as provided in the Diamond S by-laws.

Furthermore, if the Former DSS

		Holders reduce their aggregate beneficial ownership (A) by 50% or more, but less than 75%, from that owned by such Former DSS Holders as at the of the transactions contemplated by the Transaction Agreement, they will, without further action, only be entitled to designate two directors, (B) by 75% or more from that owned by such Former DSS Holders at the of the transactions contemplated by the Transaction Agreement, they will, as long as WL Ross & Co. or First Reserve Corporation continues to own at least five percent of the then outstanding common shares, only be entitled to designate one director, and (C) by an amount sufficient to cause each of WL Ross & Co., and its controlled affiliates and successors by operation of law, and First Reserve Corporation, and its controlled affiliates or successors by operation of law, to no longer own at least five percent of the then outstanding common shares, they will no longer have any nomination rights. There are currently seven directors serving on the Diamond S Board.
Election of Directors	The BCA provides that, unless otherwise required by the BCA or the articles of incorporation, directors will be elected by a plurality of the votes cast at a meeting of shareholders by the holders of shares entitled to vote in the election. The BCA also permits classified boards.
	The combined company’s articles of incorporation will provide that the directors are to be elected annually. The board of directors of the combined company is not classified. The combined company’s directors are elected if the votes cast “for” the nominee’s election by the stockholders entitled to vote at such annual meeting exceed 50% of the votes cast with respect to such nominee’s election at a meeting for the election of directors at which a quorum is present. The combined company’s by-laws will provide that the chairman of the board of directors of the combined company shall be elected by the board of directors.

Removal of Directors	The combined company’s by-laws will provide that directors may be removed with or without cause, at any time, by the affirmative vote of the holders of record of a majority of the outstanding shares of stock entitled to vote at a meeting of the stockholders.	Diamond S’ amended and restated articles of incorporation and the Diamond S by-laws provide that any director may be removed from office only by the shareholders and only for cause or pursuant to a plan of merger, consolidation or reorganization approved by shareholders, subject to the rights, if any, of the holders of any series of preferred shares to elect additional directors under circumstances specified in a preferred stock designation.
Vacancies of Directors	The combined company’s by-laws will provide that vacancies may be filled by a majority of the combined company’s directors then in office, although less than a quorum, or by the sole remaining director. Any director elected in accordance with these procedures will hold office until the next annual or special meeting of stockholders at which directors are to be elected and until the director’s successor is duly elected and qualified.	Diamond S’ amended and restated articles of incorporation and the Diamond S By-laws provide that, subject to the rights, if any, of the holders of any series of preferred shares to elect additional directors under circumstances specified in a preferred stock designation, newly created directorships resulting from any increase in the authorized number of directors and any vacancies on the Diamond S Board resulting from death, resignation, qualification, removal or other cause may be filled by the affirmative vote of a majority of the remaining directors then in office, even though less than a quorum of the Diamond S Board, or by a sole remaining director. No decrease in the authorized number of directors will shorten the term of any incumbent director.
Limitation on Liability of Directors	The BCA permits corporations to include provisions in their articles of incorporation eliminating or limiting personal liability of a director to the corporation or its stockholders for monetary damages for breach of fiduciary duty as a director. A corporation may not eliminate or limit liability for a director’s breach of the duty of loyalty to the corporation or its stockholders, for acts or omissions not undertaken in good faith or which involve intentional misconduct or a knowing violation of law, or for any transaction from which the director derived an improper personal benefit.

	Rights of Combined Company Stockholders	Rights of Diamond S Shareholders
	In accordance with the BCA, the combined company’s articles of incorporation will provide that no director will be personally liable to the combined company or its stockholders for monetary damages for breach of fiduciary duty as a director, except for liability (1) for any breach of the director’s duty of loyalty to the combined company or its stockholders, (2) for acts or omissions not in good faith or which involve intentional misconduct or a knowing violation of law, (3) under Section 28(m) of the BCA or (4) for any transaction from which the director derived an improper personal benefit.	Diamond S’ amended and restated articles of incorporation provide that, to the full extent permitted by the BCA, or any other applicable law, no director of Diamond S will be personally liable to Diamond S or its shareholders for or with respect to any acts or omissions in the performance of his or her duties as a director of Diamond S. No repeal or modification of the above provisions relating the limitation of liability of directors will adversely affect any right or protection of a director of Diamond S existing prior such repeal or modification.
Indemnification of Directors and Officers	Under the BCA, a corporation has the power to indemnify any person who was or is a party or is threatened to be made a party to any threatened, pending or completed action, suit or proceeding whether civil, criminal, administrative or investigative (other than an action by or in the right of the corporation) by reason of the fact that such person is or was a director or officer of the corporation, or is or was serving at the request of the corporation as a director or officer of another corporation, partnership, joint venture, trust or other enterprise, against expenses (including attorneys’ fees), judgments, fines and amounts paid in settlement actually and reasonably incurred by such person in connection with such action, suit or proceeding if such person acted in good faith and in a manner such person reasonably believed to be in or not opposed to the best interests of the corporation, and, with respect to any criminal action or proceeding, had no reasonable cause to believe such person’s conduct was unlawful. The termination of any action, suit or proceeding by judgment, order, settlement, conviction, or upon a plea of no contest, or its equivalent, shall not, of itself, create a presumption that the person did not act in good faith and in a manner which such person reasonably believed to be in or not opposed to the best interests of the corporation, and, with respect to any criminal action or proceeding, had reasonable cause to believe such person’s conduct was unlawful.
	A Marshall Islands corporation also has the power to indemnify any person who was or is a party or is threatened to be made a party to any threatened, pending or completed action or suit by or in the right of the corporation to procure judgment in its favor by reason of the fact that such person is or was a director or officer of the corporation, or is or was serving at the request of the corporation as a director or officer of another corporation, partnership, joint venture, trust or other enterprise against expenses (including attorneys’ fees) actually and reasonably incurred by such person or in connection with the defense or settlement of such action or suit if such person acted in good faith and in a manner such person reasonably believed to be in or not opposed to the best interests of the corporation and except that no indemnification shall be made in respect of any claim, issue or matter as to which such person shall have been adjudged to be liable for negligence or misconduct in the performance of such person’s duty to the corporation unless and only to the extent that the court in which such action or suit was brought shall determine upon application that, despite the adjudication of liability but in view of all the circumstances of the case, such

			person is fairly and reasonably entitled to indemnity for such expenses which the court shall deem proper.
			To the extent that a director or officer of a Marshall Islands corporation has been successful on the merits or otherwise in defense of any action, suit or proceeding referred to in the preceding paragraphs, or in the defense of a claim, issue or matter therein, such director or officer shall be indemnified against expenses (including attorneys’ fees) actually and reasonably incurred by such director or officer in connection therewith. Expenses incurred in defending a civil or criminal action, suit or proceeding may be paid in advance of the final disposition of such action, suit or proceeding as authorized by the board of directors in the specific case upon receipt of an undertaking by or on behalf of the director or officer to repay such amount if it shall ultimately be determined that such director or officer is not entitled to be indemnified by the corporation as authorized under the BCA.
			The BCA permits a corporation to purchase and maintain insurance on behalf of any person who is or was a director or officer of the corporation or is or was serving at the request of the corporation as a director or officer against any liability asserted against such person and incurred by such person in such capacity whether or not the corporation would have the power to indemnify such person against such liability under the BCA.
			The combined company’s by-laws will provide that the combined company shall indemnify any person (and the legal representatives of any such person) made or threatened to be made a party to or a witness in or is otherwise involved in any action, suit, claim, inquiry or proceeding, whether civil, criminal, administrative or investigative (including an action by or in the right of the combined company), referred to as a proceeding, by reason of the fact that such person is or was a director or officer of the combined company or serves or served at the request of the combined company as a director, officer, employee, trustee or agent of another corporation or of a partnership, joint venture, trust, nonprofit entity or other entity, including service with respect to employee benefit plans, against all liabilities and losses suffered and expenses (including attorneys’ fees) actually and reasonably incurred by any such person in connection with such proceeding.
			The combined company shall pay or reimburse the expenses (including attorneys’ fees) actually and reasonably incurred by any person who is or was a director or officer of the combined company, or serves or served at the request of the combined company as a director, officer, employee, trustee or agent of another corporation, or of a partnership, joint venture, trust, nonprofit entity or other entity, including service with respect to employee benefit plans, in advance of the final disposition of any such proceeding, as long as the person undertakes to repay the expenses if the final judicial decision is that the person is not entitled to be indemnified.
			Under the BCA, amendments to articles of incorporation may be authorized by the holders of a majority of all outstanding shares entitled to vote thereon. In addition, and notwithstanding any provision in the articles of incorporation to the contrary, if an amendment would increase or decrease the aggregate number of authorized shares of any class, or alter or change the powers,			Diamond S’ amended and restated articles of incorporation provide that Diamond S shall indemnify and hold harmless each person who was or is threatened to be made a party to or is otherwise involved in any threatened, pending or completed action, suit or proceeding, whether civil, criminal, administrative or investigative, by reason of the fact that such person is or was (i) a director or officer of

If any proposed amendment would alter or change the powers, preferences, or special rights of one or more series of any class so as to affect them adversely, but would not affect the entire class, then only the shares of the series so affected by the amendment shall be considered a separate class for such purposes.

Diamond S’ amended and restated articles of incorporation also provide that Diamond S shall pay the expenses (including, without limitation, attorney’s fees and expenses) of directors and officers incurred in defending any such action, suit or proceeding in advance of its final disposition; provided, however, that if the BCA so requires, an advancement of expenses incurred by a person in their capacity as an officer or director shall be made only upon delivery to Diamond S of an undertaking, by or on behalf of the director or officer, to repay all amounts advanced if it should be ultimately determined by final judicial decision from which there is no further right to appeal that the director

						or officer is not entitled to be indemnified. The rights to indemnification and advancement of expenses are contractual rights and such rights will continue as to an indemnitee who has ceased to be a director, officer employee or agent and will inure to the benefit of the indemnitee’s heirs, executors and administrators. Diamond S’ amended and restated articles of incorporation also provide that if a claim for indemnification or advancement of expenses is not paid in full by Diamond S within the timeframes set forth therein, , the indemnitee may file suit against Diamond S to recover the unpaid amount of the claim. It shall be a defense to any such action, except in certain circumstances, that the claimant has not met the standard of conduct required to indemnify the claimant for the amount claimed. Diamond S’ amended and restated and articles of incorporation also provide that Diamond S may maintain insurance, at its expense to protect itself and any director, officer, employee or agent of Diamond S or any such person who is or was serving at the request of Diamond S as a director, officer, employee or agent of another entity against any such liability asserted against such person and incurred by such person in any such capacity, whether or not Diamond S would have the power to indemnify such person under the BCA. Diamond S may, to the extent authorized from time to time by agreement, grant rights to indemnification, contribution and the advancement of expenses incurred in defending any proceeding in its final disposition to any employee, underwriter or agent of Diamond S to the extent set forth in such agreement. Diamond S has entered into indemnification agreements with persons who serve as directors or

HOUSEHOLDING OF PROXY MATERIALS

The SEC has adopted rules that permit companies and intermediaries such as brokers to satisfy delivery requirements for proxy statements and annual reports with respect to two or more stockholders sharing the same address by delivering a single proxy statement or annual report, as applicable, addressed to those stockholders. As permitted by the Exchange Act, only one copy of this joint proxy statement/prospectus is being delivered to INSW stockholders residing at the same address and only one copy of this joint proxy statement/prospectus is being delivered to Diamond S shareholders residing at the same address, unless such INSW stockholders or Diamond S shareholders, as applicable, have notified INSW or Diamond S, as applicable, of their desire to receive multiple copies of the joint proxy statement/prospectus. This process, which is commonly referred to as “householding,” potentially provides extra convenience for stockholders and cost savings for companies.

If, at any time, you no longer wish to participate in householding and would prefer to receive a separate joint proxy statement/prospectus, or if you are receiving multiple copies of this joint proxy statement/prospectus and wish to receive only one, please contact INSW or Diamond S, as applicable, at the respective address identified below. INSW or Diamond S, as applicable, will promptly deliver, upon oral or written request, a separate copy of this joint proxy statement/prospectus to any stockholder residing at an address to which only one copy was mailed.

Diamond S

Upon completion of the merger, Diamond S will become a wholly owned subsidiary of INSW and, consequently, will no longer hold annual meetings of its public company shareholders in 2022.

To be timely, the notice must be delivered to or mailed and received by Diamond S no earlier than 120 days and no later than 90 days prior to the anniversary of the preceding year’s annual meeting of shareholders. However, if the date of the annual meeting of shareholders is advanced or delayed by more than 30 days relative to the anniversary of the preceding year’s annual meeting of shareholders, such notice must be delivered by the close of business on the later of the date that is 90 days prior to such annual meeting of shareholders and 10 days following the first public announcement of the date of such annual meeting of shareholders.

Seaways shall cause the Exchange Agent to make, and the Exchange Agent shall make, delivery of the Merger Consideration, including payment of the Fractional Share Consideration and any amounts payable in respect of dividends or other distributions on Seaways Shares in accordance with Section 2.2(f) out of the Exchange Fund in accordance with this Agreement. The Exchange Fund shall not be used for any purpose that is not expressly provided for in this Agreement. The cash portion of the Exchange Fund shall be invested by the Exchange Agent as directed by Seaways; provided, however, that any investment of such cash shall in all events be limited to direct short-term obligations of, or short-term obligations backed by the full faith and credit, as to principal and interest by, the United States of America, or in commercial paper rated P-1 or A-1 or better by Moody’s Investors Service, Inc. or Standard & Poor’s Corporation, respectively, or in certificates of deposit, bank repurchase agreements or banker’s acceptances of commercial banks with capital exceeding $10 billion (based on the most recent financial statements of such bank that are then publicly available), and that no such investment or loss thereon shall affect the amounts payable to holders of Certificates or Book-Entry Shares pursuant to this Article II. Any interest and other income resulting from such investments shall, upon request by Seaways, be paid to Seaways on the earlier of (A) twelve (12) months after the Effective Time or (B) the full payment of the Exchange Fund.

(b) Procedures for Surrender. Promptly, but in any event within five (5) business days after the Effective Time, Seaways shall, and shall cause the Surviving Corporation to, cause the Exchange Agent to mail (and make available for collection by hand) or otherwise provide (i) to each holder of record of a certificate or certificates which immediately prior to the Effective Time represented outstanding Diamond Shares (the “Certificates”) whose Diamond Shares were converted pursuant to Section 2.1 into the right to receive the Merger Consideration (A) a letter of transmittal, which shall specify that delivery shall be effected, and risk of loss and title to the Certificates shall pass, only upon delivery of the Certificates (or affidavits of loss in lieu thereof) to the Exchange Agent and shall be in customary form and have such other provisions as Seaways may reasonably specify subject to Diamond’s reasonable approval prior to the Effective Time and (B) instructions for effecting the surrender of the Certificates (or affidavits of loss in lieu thereof) in exchange for payment of the Merger Consideration issuable and payable in respect of such Diamond Shares pursuant to Section 2.1, including any amount payable in respect of Fractional Share Consideration in accordance with Section 2.5, and any dividends or other distributions on Seaways Shares in accordance with Section 2.2(f) or (ii) to each holder of record of non-certificated Diamond Shares represented by book-entry (“Book-Entry Shares”) whose Diamond Shares were converted pursuant to Section 2.1 into the right to receive the Merger Consideration, a notice of the effectiveness of the Merger. Upon surrender of a Certificate (or an affidavit of loss in lieu thereof) for cancellation to the Exchange Agent or to such other agent or agents as may be appointed by Seaways or the Surviving Corporation, together with such letter of transmittal duly completed and validly executed in accordance with the instructions thereto, and such other documents as may be reasonably required pursuant to such instructions, and without any action by any holder of record of any Book-Entry Share, the holder of such Certificate or Book-Entry Share shall be entitled to receive in exchange therefor the applicable Merger Consideration pursuant to the provisions of this Article II, any Fractional Share Consideration that such holder has the right to receive pursuant to the provisions of Section 2.5, and any amounts that such holder has the right to receive in respect of dividends or other distributions on Seaways Shares in accordance with Section 2.2(f) for each Diamond Share formerly represented by such Certificate or Book-Entry Share, to be mailed (or made available for collection by hand if so elected by the surrendering holder) as promptly as practicable and, with respect to the holders of Certificates, within five (5) business days following the Exchange Agent’s receipt of such Certificate (or affidavit of loss in lieu thereof), letter of transmittal and such other documents, and the Certificate (or affidavit of loss in lieu thereof) so surrendered or Book-Entry Share shall be forthwith cancelled. The Exchange Agent shall accept such Certificates (or affidavits of loss in lieu thereof) upon compliance with such reasonable terms and conditions as the Exchange Agent may impose to effect an orderly exchange thereof in accordance with normal exchange practices. If payment of

A-5

TABLE OF CONTENTS

the Merger Consideration is to be made to a Person other than the Person in whose name the surrendered Certificate is registered, it shall be a condition precedent of payment that (A) the Certificate so surrendered shall be properly endorsed or shall be otherwise in proper form for transfer and (B) the Person requesting such payment shall have paid any transfer and other similar Taxes required by reason of the payment of the Merger Consideration to a Person other than the registered holder of the Certificate surrendered or shall have established to the satisfaction of the Surviving Corporation that such Tax either has been paid or is not required to be paid. Payment of the applicable Merger Consideration with respect to Book-Entry Shares shall only be made to the Person in whose name such Book-Entry Shares are registered. Until satisfaction of the applicable procedures contemplated by this Section 2.2(b), each Certificate and Book-Entry Share shall be deemed at any time after the Effective Time to represent only the right to receive the applicable Merger Consideration as contemplated by this Article II, including any amount payable in respect of Fractional Share Consideration in accordance with Section 2.5, and any dividends or other distributions on Seaways Shares in accordance with Section 2.2(f), without interest thereon.

(c) Transfer Books; No Further Ownership Rights in Diamond Shares. At the Effective Time, the stock transfer books of Diamond shall be closed and thereafter there shall be no further registration of transfers of Diamond Shares outstanding immediately prior to the Effective Time on the records of Diamond. From and after the Effective Time, the holders of Certificates outstanding immediately prior to the Effective Time shall cease to have any rights with respect to such Diamond Shares except as otherwise provided for herein or by applicable Law. If, after the Effective Time, Certificates or Book-Entry Shares are presented to the Surviving Corporation or the Exchange Agent for any reason, they shall be cancelled and exchanged as provided in this Agreement.

(d) Termination of Exchange Fund; No Liability. At any time following twelve (12) months after the Effective Time, Seaways shall be entitled to require the Exchange Agent to deliver to Seaways any funds (including any interest received with respect thereto) remaining in the Exchange Fund that have not been disbursed, or for which disbursement is pending subject only to the Exchange Agent’s routine administrative procedures, to holders of Certificates or Book-Entry Shares, and thereafter such holders shall be entitled to look only to the Surviving Corporation and Seaways (subject to abandoned property, escheat or other similar Laws) as general creditors thereof with respect to the applicable Merger Consideration, including any amount payable in respect of Fractional Share Consideration in accordance with Section 2.5, and any dividends or other distributions on Seaways Shares in accordance with Section 2.2(f), payable upon due surrender of their Certificates and compliance with the procedures in Section 2.2(b), without any interest thereon. Notwithstanding the foregoing, (i) none of the Surviving Corporation, Seaways or the Exchange Agent shall be liable to any holder of a Certificate or Book-Entry Share for any Merger Consideration or other amounts delivered to a public official pursuant to any applicable abandoned property, escheat or similar Law and (ii) any portion of the Merger Consideration, including any amount payable in respect of Fractional Share Consideration in accordance with Section 2.5, that remains undistributed to the holders of Certificates and Book-Entry Shares as of immediately prior to the date on which the Merger Consideration or such cash would otherwise escheat to, or become the property of, any Governmental Entity shall, to the extent permitted by applicable Law, become the property of Seaways, free and clear of all claims or interests of any Person previously entitled thereto.

(e) Lost, Stolen or Destroyed Certificates. In the event that any Certificates shall have been lost, stolen or destroyed, the Exchange Agent shall issue in exchange for such lost, stolen or destroyed Certificates, upon the making of an affidavit of that fact by the holder thereof and, if required by Seaways or the Exchange Agent, the posting by such holder of an indemnity or a bond in such amount as Seaways or the Exchange Agent may determine is reasonably necessary as indemnity against any claim that may be made against it or the Surviving Corporation with respect to any such Certificates, the applicable Merger Consideration payable in respect thereof pursuant to Section 2.1, including any amount payable in respect of Fractional Share Consideration in accordance with Section 2.5, and any dividends or other distributions on Seaways Shares in accordance with Section 2.2(f).

Subject to applicable Laws, following surrender of any such Certificate (or affidavit of loss in lieu thereof) there shall be paid to the holder thereof, without interest, (i) the amount of dividends or other distributions with a record date after the Effective Time theretofore paid with respect to such Seaways Shares to which such holder is entitled pursuant to this Agreement and (ii) at the appropriate payment date, the amount of dividends or other distributions with a record date after the Effective Time, but prior to such surrender, and with a payment date subsequent to such surrender payable with respect to such Seaways Shares.

Section 2.3 Treatment of Diamond Equity Awards.

(a) As of the Effective Time, each outstanding restricted stock unit (the “Diamond RSUs”) under the Diamond Equity Plan that is not then vested and does not vest at the Effective Time shall be assumed by Seaways and shall be converted into a restricted stock unit award for Seaways Shares (the “Seaways RSUs”) with associated rights to the issuance of additional Seaways Shares in accordance with this Section 2.3. Each Seaways RSU as so assumed and converted shall provide for full vesting (at the target level, with respect to any Diamond RSUs subject to performance-based vesting criteria) on a termination of employment without Cause or for Good Reason (as defined in the applicable award agreement) within twenty four (24) months following the Closing Date, and otherwise continue to have, and shall be subject to, the same terms and conditions as applied to the applicable Diamond RSUs immediately prior to the Effective Time (but taking into account any changes thereto, including any necessary changes to any issuance provisions, provided for or permitted in the Diamond Equity Plan, in any applicable award agreement or in such Diamond RSUs, by reason of this Agreement or the Transactions). To the extent any such Diamond RSUs are subject to performance vesting or other performance conditions, following the Effective Time, such awards shall be deemed to have achieved at least the target level of performance. As of the Effective Time, the number of Seaways Shares underlying each such Seaways RSU as so assumed and converted (which shall be rounded (x) up to the nearest whole share if half a share or more or (y) down to the nearest whole share if less than half a share) shall be equal to the product of (i) the applicable number of Diamond Shares subject to such award, multiplied by (ii) the Exchange Ratio.

(b) As of the Effective Time, each outstanding share of restricted stock (collectively, the “Diamond Restricted Shares”) granted under the Diamond Equity Plan that is not then vested and does not vest at the Effective Time shall be assumed by Seaways and shall be converted into restricted shares of Seaways (“Seaways Restricted Shares”) in accordance with this Section 2.3. Each Seaways Restricted Share as so assumed and converted shall continue to have, and shall be subject to, the same terms and conditions as applied to the applicable Diamond Restricted Shares immediately prior to the Effective Time (but taking into account any changes thereto provided for in the Diamond Equity Plan, in any applicable award agreement or in such Diamond Restricted Shares, by reason of this Agreement or the Transactions). As of the Effective Time, the number of Seaways Shares underlying each such Seaways Restricted Share as so assumed and converted (which shall be rounded (x) up to the nearest whole share if half a share or more or (y) down to the nearest whole share if less than half a share) shall be equal to the product of (i) the applicable number of Diamond Shares subject to such award, multiplied by (ii) the Exchange Ratio.

(c) Prior to the Effective Time, Diamond shall adopt such resolutions as are necessary to effect the treatment of the Diamond Restricted Shares and Diamond RSUs (collectively, the “Diamond Equity Awards”) as contemplated by this Section 2.3. At the Effective Time, Seaways shall assume all obligations of Diamond under the Diamond Equity Plan, each outstanding Diamond Equity Award and the agreements evidencing the grants thereof and shall administer and honor all such awards in accordance with the terms and conditions of such awards and the Diamond Equity Plan pursuant to which they were granted (subject to the adjustments required by reason of this Agreement or the Transactions or such other adjustments or amendments made by Seaways in accordance with such terms and conditions).

A-7

TABLE OF CONTENTS

(d) At the Effective Time, all Seaways Equity Awards shall continue on their terms and conditions and Seaways shall administer all Seaways Equity Awards in accordance with the terms and conditions of such awards and the Seaways Equity Plans pursuant to which they were granted (subject to the adjustments required by reason of this Agreement or the Transactions or such other adjustments or amendments made by Seaways in accordance with such terms and conditions).

(e) At the Effective Time, Seaways shall assume all rights and obligations in respect of the Diamond Equity Plan and will be able to grant stock awards, to the extent permissible by applicable Law under the terms of the Diamond Equity Plan if Seaways elects to assume the share reserves of the Diamond Equity Plan as of the Effective Time, except that: (i) stock covered by such awards shall be Seaways Shares; (ii) all references in Diamond Equity Plan to a number of Diamond Shares shall be amended or deemed amended to refer instead to a number of Seaways Shares determined by multiplying the number of referenced Diamond Shares by the Exchange Ratio, and rounding the resulting number down to the nearest whole number of Seaways Shares; and (iii) the Seaways Board of Directors or a committee thereof shall succeed to the authority and responsibility of the Diamond Board of Directors or any committee thereof with respect to the administration of the Diamond Equity Plan. Diamond and Seaways shall cooperate in connection with the preparation of registration statements on Form S-8 (or any successor or other appropriate form) with respect to the Diamond Equity Awards and the Seaways Equity Awards, in order to file such forms as soon as reasonably practicable following the Effective Time.

(f) Notwithstanding anything to the contrary in Article II, any payment to which a current or former employee of Diamond or any Diamond Subsidiary becomes entitled pursuant to this Section 2.3 shall be made through the Surviving Corporation’s payroll. The Surviving Corporation shall cause the Exchange Agent to make the payments under Section 2.3 payable to holders who are not current or former employees of Diamond or any Diamond Subsidiary in accordance with Section 2.2.

Section 2.4 Withholding. Notwithstanding any other provision of this Agreement, each of Seaways and the Surviving Corporation shall be entitled to (i) deduct and withhold, or cause the Exchange Agent to deduct and withhold, from the consideration otherwise payable pursuant to this Agreement any amounts as are required to be withheld or deducted with respect to such consideration under the Code, or any applicable provisions of U.S. state, local or non-U.S. Tax Law and (ii) in order to effectuate such withholding, to request any necessary Tax forms, including Form W-9 or the appropriate series of Form W-8, as applicable, or any similar information, from Diamond or its shareholders (or such shareholders’ direct and indirect owners), or any other Person to whom a payment is required to be made pursuant to this Agreement. The Parties acknowledge and agree that no such deduction or withholding is anticipated, but, in the event that any such deduction or withholding is required, the Parties shall cooperate in good faith to minimize to the extent permissible under applicable Law the amount of any such deduction or withholding. To the extent that amounts are so withheld and timely remitted to the appropriate Governmental Entity, such withheld amounts shall be treated for all purposes of this Agreement as having been paid to the Person in respect of which such deduction and withholding was made.

Section 2.5 Fractional Shares. No fractional Seaways Shares shall be issued in connection with the Merger, no certificate or scrip representing fractional Seaways Shares shall be issued upon the surrender for exchange of Certificates or Book-Entry Shares and such fractional share interests shall not entitle the owner thereof to vote or to any other rights of a shareholder of Seaways. Notwithstanding any other provision of this Agreement, each holder of Diamond Shares converted pursuant to the Merger who would otherwise have been entitled to receive a fraction of a Seaways Share (after aggregating all Diamond Shares represented by Book-Entry Shares held, and Certificates delivered, by such holder) shall receive, in lieu thereof and, in the case of Certificates, upon surrender thereof, cash, without interest, in an amount equal to the product of such fractional part of a Seaways Share (rounded to the nearest one thousandth when expressed in decimal form) and the Seaways VWAP.

Diamond, each Diamond Subsidiary and each of their respective officers and directors in their capacities as such are in material compliance with, and, since January 1, 2019, have materially complied with the applicable provisions of Sarbanes-Oxley Act and the Exchange Act.

Section 5.3 Solicitation by Diamond.

(a) From and after the date of this Agreement until the earlier of the Effective Time and the time, if any, at which this Agreement is terminated in accordance with Section 8.1, and except as otherwise specifically provided for in this Section 5.3, Diamond agrees that it shall not (and that the Diamond Board of Directors shall not and that Diamond shall cause each Diamond Subsidiary not to), and that it shall cause its and its Subsidiaries’ officers and employees not to, and that it shall use its reasonable best efforts to cause its and its Subsidiaries’ other Representatives not to, directly or indirectly: (i) solicit, initiate or knowingly encourage or knowingly facilitate any inquiry, proposal or offer, or the making, submission, modification or amendment or announcement of any inquiry, proposal or offer (including any inquiry, proposal or offer to its shareholders) which constitutes or would be reasonably expected to lead to a Diamond Competing Proposal, (ii) participate in or engage in any negotiations or discussions (other than to state that they are not permitted to have discussions) regarding, or furnish to any Person any nonpublic information relating to Diamond or any Diamond Subsidiary in connection with, any inquiry, proposal or offer which constitutes or would be reasonably expected to lead to a Diamond Competing Proposal, (iii) except in the event the Diamond Board of Directors has determined in good faith after consultation with Diamond’s outside legal counsel that the failure to take such action would be reasonably likely to constitute a breach of the fiduciary duties of the members of the Diamond Board of Directors under applicable Republic of the Marshall Islands Law, waive, terminate, modify or release any Person (other than Seaways, Merger Sub or any Seaways Subsidiary) from any provision of, or grant any permission, waiver or request under, or fail to enforce, any “standstill” or similar agreement or obligation; provided that Seaways shall notify Diamond promptly (and in any event within twenty-four (24) hours of any such waiver, termination, modification, release or grant of permission, waiver or request), (iv) approve or recommend, propose publicly to approve or recommend, or fail to timely publicly and without qualification recommend against, any Diamond Competing Proposal and reaffirm the Diamond Board Recommendation, in each case, within ten (10) business days after the Diamond Competing Proposal is made public (including upon request of Seaways to do so) (or such fewer number of days as remains prior to the date that is two (2) business days prior to the Diamond Special Meeting), (v) fail to include the Diamond Board Recommendation in the Proxy Statement/Prospectus, (vi) withdraw, change, amend, modify or qualify, or otherwise propose publicly to withdraw, change, amend, modify or qualify, in a manner adverse to Seaways, the Diamond Board Recommendation, (vii) enter into any letter of intent or other document or agreement relating to, or any agreement or commitment providing for, any Diamond Competing Proposal, other than an Acceptable Confidentiality Agreement, or (viii) resolve or agree to do any of the foregoing (any act or failure to act described in clauses (iv) through (vii) above, a “Diamond Change of Recommendation”). Diamond shall immediately cease, and cause its Subsidiaries and its and their respective directors, officers and employees to cease, and shall use its reasonable best efforts to cause its and its Subsidiaries’ other Representatives to immediately cease, any and all existing discussions or negotiations with any parties (or provision of any nonpublic information to any parties) conducted heretofore with respect to any Diamond Competing Proposal or Diamond Inquiry. Diamond shall, and shall cause its affiliates to, promptly (x) cause (to the extent it has not already done so prior to the date of this Agreement) any Person that has executed a confidentiality or non-disclosure agreement in connection with any Diamond Competing Proposal or Diamond Inquiry that remains in effect as of the date of this Agreement to return or destroy all confidential information in the possession of such Person or its Representatives in accordance with such non-disclosure agreement and (y) terminate access by any other Person and its Representatives to any physical or electronic data room or other access to data or information by Diamond or any of its Subsidiaries, in each case, relating to or in connection with, any Diamond Competing Proposal or Diamond Inquiry. Diamond shall promptly following the execution of this Agreement inform its and its relevant Subsidiaries’ Representatives of Diamond’s obligations under this Section 5.3. For purposes of this Section 5.3, the term “Person” means any Person or “group,” as defined in Section 13(d) of the Exchange Act, other than, with respect to Diamond, Seaways or any Seaways Subsidiaries. Notwithstanding anything to the contrary contained in this Agreement, Diamond, the Diamond Subsidiaries and their respective Representatives may in any event (A) seek to clarify and understand the terms and conditions of any Diamond Competing Proposal (or amended proposal) solely to determine whether such Diamond Competing Proposal constitutes or would

TABLE OF CONTENTS

reasonably be expected to lead to a Diamond Superior Proposal and (B) inform a Person that has made a Diamond Competing Proposal or an inquiry, proposal or offer which would reasonably be expected to lead to a Diamond Competing Proposal of the provisions of this Section 5.3, in each case, so long as Diamond, the Diamond Subsidiaries and their respective Representatives otherwise comply with this Section 5.3 in connection therewith.

(b) Notwithstanding the limitations set forth in Section 5.3(a), if Diamond receives, after the date hereof and prior to the receipt of the Diamond Shareholder Approval, a bona fide, unsolicited, written Diamond Competing Proposal from any Person that did not result from a breach of this Section 5.3, which the Diamond Board of Directors determines in good faith after consultation with Diamond’s outside legal and financial advisors, constitutes a Diamond Superior Proposal or is reasonably likely to lead to a Diamond Superior Proposal, then, subject to compliance with Section 5.3(c), Diamond may take the following actions: (x) furnish nonpublic information that was previously furnished to Seaways to the Person making such Diamond Competing Proposal, if, and only if, prior to so furnishing such information, Diamond receives from such Person an executed Acceptable Confidentiality Agreement (and provides a copy of such Acceptable Confidentiality Agreement to Seaways) and (y) engage in discussions or negotiations with such Person with respect to the Diamond Competing Proposal.

(c) Diamond shall notify Seaways promptly (but in no event later than twenty-four (24) hours) after receipt of any inquiry, proposal or offer that constitutes or would reasonably be expected to lead to a Diamond Competing Proposal, or any inquiry or request for nonpublic information relating to Diamond or any Diamond Subsidiary by any Person who has made or would reasonably be expected to make any Diamond Competing Proposal (each of the foregoing, a “Diamond Inquiry”). Such notice shall be made orally and confirmed in writing, and shall indicate the identity of the Person making the Diamond Inquiry or with whom Diamond is engaging in discussions or negotiations, and the material terms (including price) and conditions of any such Diamond Inquiry or the nature of the information requested pursuant to such Diamond Inquiry. In addition, Diamond shall promptly (but in any event within twenty-four (24) hours) after the receipt thereof, provide to Seaways copies of any proposed draft agreements and other written documentation material to understanding any Diamond Competing Proposal or Diamond Inquiry which is received by Diamond from any Person (or from any Representatives of such Person) making such Diamond Competing Proposal or Diamond Inquiry or with whom discussions or negotiations would reasonably be expected to lead to a Diamond Competing Proposal. Diamond shall keep Seaways reasonably informed of the status and material terms and conditions (including any amendments or proposed amendments to such material terms or conditions) of any such Diamond Competing Proposal or Diamond Inquiry and keep Seaways reasonably informed as to the nature of any information requested of Diamond or any Diamond Subsidiary or any of their respective Representatives with respect thereto. Neither Diamond nor any of its affiliates will enter into any agreement with any Person which prohibits Diamond from providing any information to Seaways in accordance with, or otherwise complying with, this Section 5.3.

(d) Notwithstanding anything in this Section 5.3 (other than Section 5.3(e)) or Section 5.5 to the contrary, at any time prior to the receipt of the Diamond Shareholder Approval, the Diamond Board of Directors may make a Diamond Change of Recommendation following receipt of a bona fide, unsolicited, written Diamond Competing Proposal, which the Diamond Board of Directors determines in good faith after consultation with Diamond’s outside legal and financial advisors is a Diamond Superior Proposal, in each case, if and only if, (x) neither Diamond nor any of its Representatives solicited, encouraged or facilitated such Diamond Competing Proposal in breach of, or is otherwise in breach of, the provisions of this Section 5.3, and (y) the Diamond Board of Directors has determined in good faith after consultation with Diamond’s outside legal counsel that the failure to take such action would be reasonably likely to constitute a breach of the fiduciary duties of the members of the Diamond Board of Directors under applicable Republic of the Marshall Islands Law.

(e) Prior to Diamond making a Diamond Change of Recommendation in accordance with Section 5.3(d), Diamond shall provide Seaways with five (5) business days’ prior written notice (it being understood and agreed that any material amendment to the applicable Diamond Competing Proposal shall require a new notice and an additional two (2) business day period) advising Seaways that the

commitment providing for, any Seaways Competing Proposal, other than an Acceptable Confidentiality Agreement, or (viii) resolve or agree to do any of the foregoing (any act or failure to act described in clauses (iv) through (vii) above, a “Seaways Change of Recommendation”). Seaways shall immediately cease, and cause its Subsidiaries and its and their respective directors, officers and employees to cease, and shall use its reasonable best efforts to cause its and its Subsidiaries’ other Representatives to immediately cease, any and all existing discussions or negotiations with any parties (or provision of any nonpublic information to any parties) conducted heretofore with respect to any Seaways Competing Proposal or Seaways Inquiry. Seaways shall, and shall cause its affiliates to, promptly (x) cause (to the extent it has not already done so prior to the date of this Agreement) any Person that has executed a confidentiality or non-disclosure agreement in connection with any Seaways Competing Proposal or Seaways Inquiry that remains in effect as of the date of this Agreement to return or destroy all confidential information in the possession of such Person or its Representatives in accordance with such non-disclosure agreement and (y) terminate access by any other Person and its Representatives to any physical or electronic data room or other access to data or information by Seaways or any of its Subsidiaries, in each case, relating to or in connection with, any Seaways Competing Proposal or Seaways Inquiry. Diamond. Seaways shall promptly following the execution of this Agreement inform its and its relevant Subsidiaries’ Representatives of Seaways’ obligations under this Section 5.4. For purposes of this Section 5.4, the term “Person” means any Person or “group,” as defined in Section 13(d) of the Exchange Act, other than, with respect to Seaways, Diamond or any Diamond Subsidiaries. Notwithstanding anything to the contrary contained in this Agreement, Seaways, the Seaways Subsidiaries and their respective Representatives may in any event (A) seek to clarify and understand the terms and conditions of any Seaways Competing Proposal (or amended proposal) solely to determine whether such Seaways Competing Proposal constitutes or would reasonably be expected to lead to a Seaways Superior Proposal and (B) inform a Person that has made a Seaways Competing Proposal or an inquiry, proposal or offer which would reasonably be expected to lead to a Seaways Competing Proposal of the provisions of this Section 5.4, in each case, so long as Seaways, the Seaways Subsidiaries and their respective Representatives otherwise comply with this Section 5.4 in connection therewith.

(b) Notwithstanding the limitations set forth in Section 5.4(a), if Seaways receives, after the date hereof and prior to the receipt of the Seaways Shareholder Approval, a bona fide, unsolicited, written Seaways Competing Proposal from any Person that did not result from a breach of this Section 5.4, which the Seaways Board of Directors determines in good faith after consultation with Seaways’ outside legal and financial advisors constitutes a Seaways Superior Proposal or is reasonably likely to lead to a Seaways Superior Proposal, then, subject to compliance with Section 5.4(c), Seaways may take the following actions: (x) furnish nonpublic information that was previously furnished to Diamond to the Person making such Seaways Competing Proposal, if, and only if, prior to so furnishing such information, Seaways receives from such Person an executed Acceptable Confidentiality Agreement and (y) engage in discussions or negotiations with such Person with respect to the Seaways Competing Proposal (and provides a copy of such Acceptable Confidentiality Agreement to Diamond).

(c) Seaways shall notify Diamond promptly (but in no event later than twenty-four (24) hours) after receipt of any inquiry, proposal or offer that constitutes or would reasonably be expected to lead to a Seaways Competing Proposal, or any inquiry or request for nonpublic information relating to Seaways or any Seaways Subsidiary by any Person who has made or would reasonably be expected to make any Seaways Competing Proposal (each of the foregoing, a “Seaways Inquiry”). Such notice shall be made orally and confirmed in writing, and shall indicate the identity of the Person making the Seaways Inquiry or with whom Seaways is engaging in discussions or negotiations, and the material terms (including price) and conditions of any such Seaways Inquiry or the nature of the information requested pursuant to such Seaways Inquiry. In addition, Seaways shall promptly (but in any event within twenty-four (24) hours) after the receipt thereof, provide to Diamond copies of any proposed draft agreements and other written documentation material to understanding any Seaways Competing Proposal or Seaways Inquiry which is received by Seaways from any Person (or from any Representatives of such Person) making such Seaways Competing Proposal or Seaways Inquiry or with whom discussions or negotiations would reasonably be expected to lead to a Seaways Competing Proposal. Seaways shall keep Diamond reasonably informed of the status and material terms and conditions (including any amendments or proposed amendments to such material terms or conditions) of any such Seaways Competing Proposal or Seaways Inquiry and keep Diamond reasonably informed as to the

nature of any information requested of Seaways or any Seaways Subsidiary or any of their respective Representatives with respect thereto. Neither Seaways nor any of its affiliates will enter into any agreement with any Person which prohibits Seaways from providing any information to Diamond in accordance with, or otherwise complying with, this Section 5.4.

(d) Notwithstanding anything in this Section 5.4 (other than Section 5.4(e)) or Section 5.5 to the contrary, at any time prior to the receipt of the Seaways Shareholder Approval, the Seaways Board of Directors may make a Seaways Change of Recommendation following receipt of a bona fide, unsolicited, written Seaways Competing Proposal, which the Seaways Board of Directors determines in good faith after consultation with Seaways’ outside legal and financial advisors is a Seaways Superior Proposal, in each case, if and only if, (x) neither Seaways nor any of its Representatives solicited, encouraged or facilitated such Seaways Competing Proposal in breach of, or is otherwise in breach of, the provisions of this Section 5.4, and (y) the Seaways Board of Directors has determined in good faith after consultation with Seaways’ outside legal counsel that the failure to take such action would be reasonably likely to constitute a breach of the fiduciary duties of the members of the Seaways Board of Directors under applicable Republic of the Marshall Islands Law.

(e) Prior to Seaways making a Seaways Change of Recommendation in accordance with Section 5.4(d), Seaways shall provide Diamond with five (5) business days’ prior written notice (it being understood and agreed that any material amendment to the applicable Seaways Competing Proposal shall require a new notice and an additional two (2) business day period) advising Diamond that the Seaways Board of Directors intends to take such action and contemporaneously providing to Diamond a copy of the Seaways Superior Proposal, a copy of any proposed agreements for such Seaways Superior Proposal (including any financing commitments related thereto) and indicating the identity of the Person making such Seaways Competing Proposal (or, in each case, if not provided in writing to Seaways or any of its Representatives, a written summary of the terms thereof), and during such initial (5) business day or subsequent two (2) business day period, (x) Seaways shall negotiate, and cause its Representatives to negotiate, with Diamond and its Representatives in good faith (to the extent Diamond wishes to negotiate) to enable Diamond to determine whether to propose revisions to the terms of this Agreement or any other agreement related to the Transactions such that such Seaways Competing Proposal would no longer constitute a Seaways Superior Proposal and (y) Seaways shall consider in good faith any proposal by Diamond to amend the terms and conditions of this Agreement or any other agreement related to the Transactions such that such Seaways Competing Proposal would no longer constitute a Seaways Superior Proposal.

provisions of the Exchange Act or Securities Act and (4) keep the Form S-4 effective for so long as necessary to complete the Merger.

No filing of, or amendment or supplement to, the Form S-4 or the Proxy Statement/Prospectus will be made by Diamond or Seaways, as applicable, without the other’s prior written consent (not to be unreasonably withheld, conditioned or delayed) and without providing the other Party a reasonable opportunity to review and comment thereon. Seaways shall advise Diamond, promptly after it receives notice thereof, of the time of effectiveness of the Form S-4 or upon filing any supplement or amendment thereto, the issuance of any stop order relating thereto or the suspension of the qualification of the Seaways Shares issuable in connection with the Merger for offering or sale in any jurisdiction, and Seaways shall use its reasonable best efforts to have any such stop order or suspension lifted, reversed or otherwise terminated.

Each of Diamond and Seaways will use its reasonable best efforts to ensure that the information relating to Diamond and its affiliates, officers and directors in the case of Diamond, and relating to Seaways and its affiliates, officers and directors in the case of Seaways, contained in the Form S-4 and the Proxy Statement/Prospectus will not, (x) in the case of the Proxy Statement/Prospectus, on the date the Proxy Statement/Prospectus (and any amendment or supplement thereto) is first mailed to the shareholders of Diamond or Seaways and (y) in the case of the Form S-4, at the time the Form S-4 (and any amendment or supplement thereto) is filed and the date it is declared effective or any post-effective amendment thereto is filed or is declared effective, or at the time of the Seaways Special Meeting (as it may be adjourned or postponed in accordance with the terms hereof), contain any untrue statement of any material fact or omit to state any material fact required to be stated therein or necessary in order to make the statements therein, at the time and in light of the circumstances under which they were made, not false or misleading.

(b) If any information relating to Diamond or Seaways, respectively, or any of their respective affiliates, officers or directors, should be discovered by Diamond or Seaways which, in the reasonable judgment of Diamond or Seaways, respectively, should be set forth in an amendment of, or a supplement to, any of the Form S-4 or the Proxy Statement/Prospectus so that any of such documents would not include any misstatement of a material fact or omit to state any material fact necessary to make the statements therein, in light of the circumstances under which they were made, not misleading, the Party

which discovers such information shall promptly notify the other Parties, and Diamond and Seaways shall cooperate in the prompt filing with the SEC of any necessary amendment of, or supplement to, the Proxy Statement/Prospectus or the Form S-4 and, to the extent required by Law, in disseminating the information contained in such amendment or supplement to shareholders of Diamond and the shareholders of Seaways. Nothing in this Section 5.5(b) shall limit the obligations of any Party under Section 5.5(a). For purposes of this Section 5.5, any information concerning or related to Diamond, its affiliates or the Diamond Special Meeting will be deemed to have been provided by Diamond, and any information concerning or related to Seaways, its affiliates or the Seaways Special Meeting will be deemed to have been provided by Seaways.

Diamond shall, through the Diamond Board of Directors, make the Diamond Board Recommendation, include such Diamond Board Recommendation in the Proxy Statement/Prospectus and solicit and use its reasonable best efforts to obtain the Diamond Shareholder Approval, except in each case to the extent that the Diamond Board of Directors shall have made a Diamond Change of Recommendation as permitted by Section 5.3. Notwithstanding the foregoing provisions of this Section 5.5(c), Diamond shall have the right, following consultation with Seaways, to make (and, if so requested by Seaways, shall be required to make) one or more successive postponements or adjournments of the Diamond Special Meeting of not more than fifteen (15) days individually (i) if, on a date for which the Diamond Special Meeting is scheduled, Diamond has not received proxies representing a sufficient number of Diamond Shares to obtain the Diamond Shareholder Approval, whether or not a quorum is present, or (ii) if such adjournment or postponement is required by applicable Law, including to the extent such adjournment or postponement is required under applicable Law to ensure that any required supplement or amendment to the Proxy Statement/Prospectus is provided or made available to Diamond shareholders or to permit dissemination of information which is material to shareholders voting at the Diamond Special Meeting and to give Diamond shareholders sufficient time to evaluate any such supplement or amendment or other information; provided that the Diamond Special Meeting shall not be postponed or adjourned to a date that is in the aggregate more than thirty (30) days after the date for which the Diamond Special Meeting was originally scheduled (without giving effect to any postponement).

(c) Seaways shall cause the Surviving Corporation to maintain, for an aggregate period of not less than six (6) years from the Effective Time, the current directors’ and officers’ liability insurance policy maintained by Diamond with respect to claims arising from facts or events occurring at or prior to the Effective Time (the “D&O Insurance”); provided, however, that the Surviving Corporation shall not be required to pay an annual premium for the D&O Insurance in excess of four hundred percent (400%) of the last annual premium paid prior to the date of this Agreement by Diamond for such policy and if such premium for such insurance would at any time exceed such cap, then the Surviving Corporation shall cause to be maintained an insurance policy which, in the Surviving Corporation’s good faith determination, provides the maximum coverage available at an annual premium equal to such cap; provided, further, that Diamond may, prior to the Effective Time, substitute therefor a tail policy to Diamond’s current directors’ and officer’s liability insurance policy providing equivalent coverage with a cost not in excess of four hundred percent (400%) of the last annual premium paid prior to the date of this Agreement by Diamond for such policy. Diamond shall reasonably cooperate with Seaways prior to the Effective Time to enable Seaways, at the election of Seaways, to purchase such a tail policy. Notwithstanding anything in this Section 6.4 to the contrary, if any Indemnified Party notifies Seaways on or prior to the sixth anniversary of the Effective Time of a matter in respect of which such Person may seek indemnification pursuant to this Section 6.4, the provisions of this Section 6.4 that require the Surviving Corporation to indemnify and advance expenses shall continue in effect with respect to such matter until the final disposition of all claims, actions, investigations, suits and proceedings relating thereto.

The provisions of this Section 6.4 shall survive the Effective Time and are intended to be for the benefit of, and shall be enforceable by, each Indemnified Party and his or her heirs and Representatives.

For any Continuing Employee who is terminated by the Post-Closing Employer without cause (as determined by the Post-Closing Employer in its sole discretion) on or prior to December 31, 2021 and who is not party to an agreement that provides a contractual right to severance or other termination benefits, the Post-Closing Employer will provide such Continuing Employee with the severance benefits set forth in, and subject to the terms and conditions of, Section 6.7(a)(ii) of the Disclosure Letter.

(b) Following the Effective Time and upon the transition of the Continuing Employees to the Post-Closing Employer’s health and welfare benefit plans (the “New Benefit Plans”), (i) Seaways shall use commercially reasonable efforts, or shall use commercially reasonable efforts to cause the Post-Closing Employer to take commercially reasonable steps to ensure that no limitations or exclusions as to pre-existing conditions, evidence of insurability or good health, waiting periods or actively-at-work exclusions or other limitations or restrictions on coverage are applicable to any Continuing Employees or their dependents or beneficiaries under the New Benefit Plans and (ii) Seaways shall use commercially reasonable efforts, or shall use commercially reasonable efforts to cause the Post-Closing Employer to take commercially reasonable steps to provide that any costs or expenses incurred by Continuing Employees (and their dependents or beneficiaries) up to (and including) the Effective Time shall be taken into account for purposes of satisfying applicable deductible, co-payment, coinsurance, maximum out-of-pocket provisions and like adjustments or limitations on coverage under any such New Benefit Plan.

In some instances, the representations and warranties in this Agreement may represent an allocation among the Parties of risks associated with particular matters regardless of the knowledge of any of the Parties. Consequently, Persons other than the Parties may not rely upon the representations and warranties in this Agreement as characterizations of actual facts or circumstances as of the date of this Agreement or as of any other date.

Section 9.10 Severability. If any term or other provision of this Agreement is invalid, illegal or incapable of being enforced by rule of Law or public policy, all other conditions and provisions of this Agreement shall nevertheless remain in full force and effect so long as the economic or legal substance of the Merger is not affected in any manner adverse to any Party. Upon such determination that any term

A-88

or other provision is invalid, illegal or incapable of being enforced, the Parties shall negotiate in good faith to modify this Agreement so as to effect the original intent of the Parties as closely as possible in an acceptable manner to the end that the Merger are fulfilled to the extent possible.

Section 9.11 Governing Law; Jurisdiction.

(a) This Agreement shall be governed by, and construed in accordance with, the laws of the State of Delaware, without giving effect to conflicts of laws principles that would result in the application of the Law of any other jurisdiction, except (i) to the extent that the law of the Republic of the Marshall Islands is mandatorily applicable to the Merger and (ii) all matters relating to the fiduciary duties of the Diamond Board of Directors and Seaways Board of Directors shall be subject to the laws of the Republic of the Marshall Islands.

Each of the Parties hereto agrees that a final judgment in any such action or proceeding shall be conclusive and may be enforced in other jurisdictions by suit on the judgment or in any other manner provided by Law. Each Party to this Agreement irrevocably consents to service of process inside or outside the territorial jurisdiction of the courts referred to in this Section 9.11(b) in the manner provided for notices in Section 9.4. Nothing in this Agreement will affect the right of any Party to this Agreement to serve process in any other manner permitted by Law.

Section 9.12 Waiver of Jury Trial. EACH PARTY HEREBY IRREVOCABLY AND UNCONDITIONALLY WAIVES ANY RIGHT IT MAY HAVE TO A TRIAL BY JURY IN RESPECT OF ANY LITIGATION DIRECTLY OR INDIRECTLY ARISING OUT OF OR RELATING TO THIS AGREEMENT AND ANY OF THE AGREEMENTS DELIVERED IN CONNECTION HEREWITH OR THE MERGER AND OTHER TRANSACTIONS CONTEMPLATED HEREBY OR THEREBY. EACH PARTY CERTIFIES AND ACKNOWLEDGES THAT (A) NO REPRESENTATIVE, AGENT OR ATTORNEY OF ANY OTHER PARTY HAS REPRESENTED, EXPRESSLY OR OTHERWISE, THAT SUCH OTHER PARTY WOULD NOT, IN THE EVENT OF LITIGATION, SEEK TO ENFORCE EITHER OF SUCH WAIVERS, (B) IT UNDERSTANDS AND HAS CONSIDERED THE IMPLICATIONS OF SUCH WAIVERS, (C) IT MAKES SUCH WAIVERS VOLUNTARILY, AND (D) IT HAS BEEN INDUCED TO ENTER INTO THIS AGREEMENT BY, AMONG OTHER THINGS, THE MUTUAL WAIVERS AND CERTIFICATIONS IN THIS SECTION 9.12.

Section 9.13 Assignment. This Agreement shall not be assigned by any of the Parties (whether by operation of Law or otherwise) without the prior written consent of the other Parties, except Merger Sub may assign any or all of its rights, interests and obligations hereunder to (i) Seaways, (ii) Seaways and one or more direct or indirect wholly owned Subsidiaries of Seaways or (iii) one or more direct or indirect wholly owned Subsidiaries of Seaways; provided, that no such assignment shall be permitted without the prior written consent of Diamond if such assignment could increase the risk that any of the conditions set forth in Article VII may not be timely satisfied, or result in a breach of any of covenants and agreements set forth in this Agreement or adversely affect Diamond; provided, further, that no such assignment shall relieve Seaways or Merger Sub of any obligation or liability under this Agreement. Subject to the preceding sentence, but without relieving any Party of any obligation hereunder, this Agreement will be binding upon, inure to the benefit of and be enforceable by the Parties and their respective successors and assigns and this Agreement is not intended to, and shall not, confer upon any other Person other than the Parties and their respective successors and permitted assigns any rights or remedies hereunder.

Section 9.14 Enforcement; Remedies.

(a) Except as otherwise expressly provided herein, any and all remedies herein expressly conferred upon a Party will be deemed cumulative with and not exclusive of any other remedy conferred hereby, or by Law or equity upon such Party, and the exercise by a Party of any one remedy will not preclude the exercise of any other remedy.

(b) The Parties agree that irreparable injury will occur in the event that any of the provisions of this Agreement is not performed in accordance with its specific terms or is otherwise breached. It is agreed that prior to the termination of this Agreement pursuant to Article VIII, each Party shall be entitled to an injunction or injunctions to prevent or remedy any breaches or threatened breaches of this Agreement by any other Party, to a decree or order of specific performance to specifically enforce the terms and provisions of this Agreement and to any further equitable relief. Each of the Parties hereby acknowledges and agrees that it may be difficult to prove damages with reasonable certainty, that it may be difficult to procure suitable substitute performance, and that injunctive relief and/or specific performance will not cause an undue hardship to the Parties. Each of the Parties hereby further acknowledges that the existence of any other remedy contemplated by this Agreement does not diminish the availability of specific performance of the obligations hereunder or any other injunctive relief.

(c) The Parties’ rights in this Section 9.14 are an integral part of the Transactions and each Party hereby waives any objections to any remedy referred to in this Section 9.14 (including any objection on the basis that there is an adequate remedy at Law or that an award of such remedy is not an appropriate remedy for any reason at Law or equity). For the avoidance of doubt, each Party agrees that there is not an adequate remedy at Law for a breach of this Agreement by any Party. In the event any Party seeks any remedy referred to in this Section 9.14, such Party shall not be required to obtain, furnish, post or provide any bond or other security in connection with or as a condition to obtaining any such remedy.

AMENDED AND RESTATED ARTICLES OF INCORPORATION OF DIAMOND S SHIPPING INC.

PURSUANT TO THE MARSHALL ISLANDS BUSINESS CORPORATIONS ACT

The undersigned, for the purpose of forming a corporation pursuant to the provisions of the Marshall Islands Business Corporations Act (the “BCA”), does hereby make, subscribe, acknowledge and file with the Registrar of Corporations the following Articles of Incorporation (these “Articles”) for that purpose, as follows:

ARTICLE ONE

The name of the Corporation shall be Diamond S Shipping Inc. (the “Corporation”).

The purpose of the Corporation is to engage in any lawful act or activity for which corporations may now or hereafter be organized under the BCA.

ARTICLE FOUR

The aggregate number of shares of stock that the Corporation is authorized to issue is five hundred (500) registered shares, which will be designated common stock, par value $0.001.

ARTICLE SIX

The name and address of the incorporator is:

	Name			Address
	Majuro Nominees Ltd.			P.O. Box 1405
				Majuro
				Marshall Islands

ARTICLE SEVEN

The board of directors of the Corporation (the “Board of Directors”) may from time to time adopt, amend or repeal the bylaws of the Company (the “Bylaws”), subject to the power of the shareholders to adopt any Bylaws or to amend or repeal any Bylaws adopted, amended or repealed by the Board of Directors.

ARTICLE EIGHT

To the full extent permitted by the BCA or any other applicable law currently or hereafter in effect, no director of the Corporation will be personally liable to the Corporation or its shareholders for or with respect to any acts or omissions in the performance of his or her duties as a director of the Corporation. Any repeal or modification of this Article Eight may not adversely affect any right or protection of a director of the Corporation existing prior to such repeal or modification.

ARTICLE NINE

Section 1. Rights to Indemnification. Each person who is or was a party or is threatened to be made a party to or is otherwise involved in any threatened, pending or completed action, suit or proceeding,

TABLE OF CONTENTS

whether civil, criminal, administrative or investigative (a “Proceeding”), by reason of the fact that the person is or was a director or an officer of the Corporation, or is or was serving at the request of the Corporation as a director, officer, employee or agent of another corporation, partnership, joint venture, trust or other enterprise, including service with respect to an employee benefit plan (an “Indemnitee”), whether the basis of such Proceeding is alleged action in an official capacity as a director, officer, employee or agent or in any other capacity while serving as a director, officer, employee or agent, will be indemnified and held harmless by the Corporation to the fullest extent permitted or required by the BCA, as the same exists or may hereafter be amended (but, in the case of any such amendment, only to the extent that such amendment permits the Corporation to provide broader indemnification rights than such law permitted the Corporation to provide prior to such amendment), against all expense, liability and loss (including attorneys’ fees, judgments, fines, excise taxes or penalties and amounts paid in settlement) reasonably incurred or suffered by such Indemnitee in connection therewith; provided, however, that, except as provided in Section 3 of this Article Nine with respect to Proceedings to enforce rights to indemnification, the Corporation will indemnify any such Indemnitee in connection with a Proceeding (or part thereof) initiated by such Indemnitee only if such Proceeding (or part thereof) was authorized by the Board of Directors.

Section 2. Rights to Advancement of Expenses. The right to indemnification conferred in Section 1 of this Article Nine includes the right to be paid by the Corporation the expenses (including, without limitation, attorneys’ fees and expenses) incurred in defending any such Proceeding in advance of its final disposition (an “Advancement of Expenses”); provided, however, that, if the BCA so requires, an Advancement of Expenses incurred by an Indemnitee in such person’s capacity as a director or officer (and not in any other capacity in which service was or is rendered by such Indemnitee, including, without limitation, service to an employee benefit plan) will be made only upon delivery to the Corporation of an undertaking (an “Undertaking”), by or on behalf of such Indemnitee, to repay all amounts so advanced if it is ultimately determined by final judicial decision from which there is no further right to appeal (a “Final Adjudication”) that such Indemnitee is not entitled to be indemnified for such expenses under this Section 2 or otherwise. The rights to indemnification and to the Advancement of Expenses conferred in Sections 1 and 2 of this Article Nine will be contractual rights and such rights will continue as to an Indemnitee who has ceased to be a director, officer, employee or agent and will inure to the benefit of the Indemnitee’s heirs, executors and administrators.

Section 3. Rights of Indemnitee to Bring Suit. If a claim under Section 1 or 2 of this Article Nine is not paid in full by the Corporation within 60 calendar days after a written claim has been received by the Corporation, except in the case of a claim for an Advancement of Expenses, in which case the applicable period will be 20 calendar days, the Indemnitee may at any time thereafter bring suit against the Corporation to recover the unpaid amount of the claim. If successful in whole or in part in any such suit, or in a suit brought by the Corporation to recover an Advancement of Expenses pursuant to the terms of an Undertaking, the Indemnitee will be entitled to be paid also the expense of prosecuting or defending such suit. In (a) any suit brought by the Indemnitee to enforce a right to indemnification hereunder (but not in a suit brought by the Indemnitee to enforce a right to an Advancement of Expenses) it will be a defense, and (b) any suit brought by the Corporation to recover an Advancement of Expenses pursuant to the terms of an Undertaking, the Corporation is entitled to recover such expenses upon a Final Adjudication, that the Indemnitee has not met any applicable standard for indemnification set forth in the BCA. Neither the failure of the Corporation (including the Board, a Board committee or the Corporation’s independent legal counsel or shareholders) to have made a determination prior to the commencement of such suit that indemnification of the Indemnitee is proper in the circumstances because the Indemnitee has met the applicable standard of conduct set forth in the BCA, nor an actual determination by the Corporation (including the Board, a Board committee, or the Corporation’s independent legal counsel or shareholders) that the Indemnitee has not met such applicable standard of conduct, will create a presumption that the Indemnitee has not met the applicable standard of conduct or, in the case of such a suit brought by the Indemnitee, be a defense to such suit. In any suit brought by the Indemnitee to enforce a right to indemnification or to an Advancement of Expenses hereunder, or brought by the Corporation to recover an Advancement of Expenses pursuant to the terms of an Undertaking, the burden of proving that the Indemnitee is not entitled to be indemnified, or to such Advancement of Expenses, under this Article Nine or otherwise will be on the Corporation.

Section 4. Non-Exclusivity Rights. The rights to indemnification and to the Advancement of Expenses conferred in this Article Nine will not be exclusive of any other right that any person may have or

TABLE OF CONTENTS

hereafter acquire under any statute, these Articles, Bylaws, any agreement, vote of shareholders or disinterested directors or otherwise.

Section 5. Insurance. The Corporation may maintain insurance, at its expense, to protect itself and any person who is or was a director, officer, employee or agent of the Corporation, or is or was serving at the request of the Corporation as a director, officer, employee or agent of another corporation, partnership, joint venture, trust or other enterprise against any liability asserted against such person and incurred by such person in any such capacity, or arising out of such person’s status as such, whether or not the Corporation would have the power to indemnify such person against such liability under the BCA.

Section 6. Indemnification of Employees and Agents of the Corporation. Indemnification of Employees and Agents of the Company. The Company may, to the extent authorized from time to time by agreement, grant rights to indemnification, contribution and to the Advancement of Expenses to any employee, underwriter or agent of the Company to the extent set forth in such agreement whether or not subject to the provisions of this Article Nine with respect to the indemnification and Advancement of Expenses of directors and officers of the Company.

ARTICLE TEN

The Corporate existence shall begin upon filing these Articles with the Registrar of Corporations as of the filing date stated on these Articles.

[MISSING IMAGE: LG_JEFFERIESLLLCTRHD-K.JPG]

March 30, 2021

The Board of Directors
International Seaways, Inc.
600 Third Avenue, 39th Floor
New York, NY 10016

Members of the Board:

We understand that International Seaways, Inc. (“Seaways”), Dispatch Transaction Sub, Inc., a wholly-owned subsidiary of Seaways (“Merger Sub”), and Diamond S Shipping Inc. (“Diamond”) propose to enter into an Agreement and Plan of Merger (the “Merger Agreement”), pursuant to which, among other things, Merger Sub will merge with and into Diamond (the “Merger”) in a transaction in which each issued and outstanding common share, par value $0.001 per share, of Diamond (the “Diamond Common Stock”), other than shares of Diamond Common Stock owned by Diamond, Seaways, Merger Sub or any of their respective wholly owned subsidiaries, all of which shares will be canceled, will be converted into the right to receive 0.55375 (the “Exchange Ratio”) registered shares, without par value, of Seaways (the “Seaways Common Shares”). The Exchange Ratio is subject to adjustment as set forth in the Merger Agreement and we express no opinion as to such adjustment. The terms and conditions of the Merger are more fully set forth in the Merger Agreement.

You have asked for our opinion as to whether the Exchange Ratio provided for in the Merger pursuant to the Merger Agreement is fair, from a financial point of view, to Seaways.

In arriving at our opinion, we have, among other things:

(i)

reviewed a draft dated March 30, 2021 of the Merger Agreement;

(ii)

reviewed certain publicly available financial and other information about Diamond and Seaways;

(iii)

reviewed certain information furnished to us by Diamond’s management, including financial forecasts and analyses relating to the business, operations and prospects of Diamond (the “Diamond Forecasts”);

(iv)

reviewed certain information furnished to us by Seaways’ management, including (a) an alternative version of the Diamond Forecasts incorporating certain adjustments thereto made and approved for our use by the senior management of Seaways (the “Adjusted Diamond Forecasts”), and (b) financial forecasts and analyses, relating to the business, operations and prospects of Seaways (the “Seaways Forecasts”);

(v)

held discussions with members of senior management of Diamond concerning the matters described in clauses (ii) and (iii) above and with members of senior management of Seaways concerning the matters described in clauses (ii) through (iv) above;

(vi)

reviewed certain third party appraisals and valuation estimates relating to certain assets of Diamond and Seaways, in each case as approved for our use by the senior management of Seaways (collectively, the “Appraisals and Valuation Estimates”);

B-1

TABLE OF CONTENTS

(vii)

reviewed the share trading price history and valuation multiples for the Diamond Common Stock and the Seaways Common Shares and compared them with those of certain publicly traded companies that we deemed relevant;

(viii)

compared the proposed financial terms of the Merger with the financial terms of certain other transactions that we deemed relevant; and

(ix)

conducted such other financial studies, analyses and investigations as we deemed appropriate.

In our review and analyses and in rendering this opinion, we have assumed and relied upon, but have not assumed any responsibility to independently investigate or verify, the accuracy and completeness of all financial and other information that was supplied or otherwise made available by Diamond or Seaways or that was publicly available to us (including, without limitation, the Appraisals and Valuation Estimates and the other information described above), or that was otherwise reviewed by us. With regard to the Appraisals and Valuation Estimates, we have assumed, with your consent, that they provide an appropriate basis for evaluating Diamond and Seaways, as applicable, and we have relied upon such Appraisals and Valuation Estimates in our review and analyses and in rendering this opinion. We have relied on assurances of the managements of Diamond and Seaways that they are not aware of any facts or circumstances that would make any of the foregoing information inaccurate or misleading. In our review, we did not obtain any independent evaluation or appraisal of any of the assets or liabilities (contingent, accrued, derivative, off-balance sheet or otherwise), nor did we conduct a physical inspection of any of the properties or facilities, of Diamond or Seaways, and we have not been furnished with (in each case, other than the Appraisals and Valuation Estimates), and assume no responsibility to obtain, any such evaluations, appraisals or physical inspections. We have not evaluated the solvency or fair value of Diamond, Seaways or any other entity under any laws relating to bankruptcy, insolvency or similar matters.

With respect to the financial forecasts and estimates provided to and reviewed by us, we note that projecting future results of any company is inherently subject to uncertainty. However, we have been advised, and we have assumed, that the Diamond Forecasts were reasonably prepared on bases reflecting the best currently available estimates and good faith judgments of the management of Diamond as to the future financial performance of Diamond and the other matters covered thereby, and the Adjusted Diamond Forecasts and the Seaways Forecasts were reasonably prepared on bases reflecting the best currently available estimates and good faith judgments of the management of Seaways as to the future financial performance of Diamond and Seaways, respectively, and the other matters covered thereby. With regard to the financial forecasts and estimates relating to Diamond, at your direction we have relied upon the Adjusted Diamond Forecasts in our review and analyses and in rendering this opinion. We express no opinion as to such financial forecasts or estimates or the assumptions on which they are based.

Our opinion is based on economic, monetary, regulatory, market and other conditions existing and which can be evaluated as of the date hereof. We expressly disclaim any undertaking or obligation to advise any person of any change in any fact or matter affecting our opinion of which we become aware after the date hereof.

We have made no independent investigation of, and we express no view or opinion as to, any legal, regulatory, accounting or tax matters affecting or relating to Diamond, Seaways or the Merger, and we have assumed the correctness in all respects material to our analyses and opinion of all legal, regulatory, accounting and tax advice given to Seaways and/or the Board of Directors of Seaways (the “Board”), including, without limitation, with respect to changes in, or the impact of, accounting standards or tax and other laws, regulations and governmental and legislative policies affecting Diamond, Seaways or the Merger and legal, regulatory, accounting and tax consequences to Seaways of the terms of, and transactions contemplated by, the Merger Agreement and related documents. You have advised us that the Merger will qualify as a tax free reorganization for federal income tax purposes. We have assumed that the Merger will be consummated in accordance with the terms of the Merger Agreement without waiver, modification or amendment of any material term, condition or agreement and in compliance with all applicable laws, documents and other requirements and that the final form of the Merger Agreement will be substantially similar to the last draft reviewed by us. We have also assumed that in the course of obtaining the necessary governmental, regulatory or third-party approvals, consents, waivers and releases for the Merger or otherwise,

B-2

TABLE OF CONTENTS

including with respect to any divestitures or other requirements, no delay, limitation, restriction or condition will be imposed or occur that would have an adverse effect on Diamond, Seaways or the contemplated benefits of the Merger or that otherwise would be material in any respect to our analyses or opinion.

Our opinion does not address the relative merits of the transactions contemplated by the Merger Agreement as compared to any alternative transaction or opportunity that might be available to Seaways, nor does it address the underlying business decision by Seaways to engage in the Merger or the terms of the Merger Agreement or the documents referred to therein, including the form or structure of the Merger or any term, aspect or implication of any voting agreements, derivatives arrangements or other agreements, arrangements or understandings entered into in connection with, or contemplated by or resulting from, the Merger or otherwise. We have not been asked to address, and our opinion does not address, the fairness to, or any other consideration of, the holders of any class of securities, creditors or other constituencies of Seaways or any other party. We express no view or opinion as to the prices at which the Seaways Common Shares may trade or otherwise be transferrable at any time. Furthermore, we do not express any view or opinion as to the fairness, financial or otherwise, of the amount or nature of any compensation or other consideration payable to or to be received by any officers, directors or employees, or any class of such persons, in connection with the Merger relative to the Exchange Ratio or otherwise. The issuance of this opinion has been authorized by the Fairness Committee of Jefferies LLC.

It is understood that our opinion is for the use and benefit of the Board (in its capacity as such) in its consideration of the Merger. Our opinion does not constitute a recommendation as to how any holder of Seaways Common Shares should vote on the Merger or any other matter.

We have been engaged by Seaways to act as its financial advisor in connection with the Merger and will receive a fee for our services, a portion of which is payable upon delivery of this opinion and a significant portion of which is payable contingent upon consummation of the Merger. We also will be reimbursed for expenses incurred. Seaways has also agreed to indemnify us against liabilities arising out of or in connection with the services rendered and to be rendered by us under such engagement.

We have, in the past, provided financial advisory and financing services to Seaways and may continue to do so and have received, and may receive, fees for the rendering of such services. In the ordinary course of our business, we and our affiliates may trade or hold securities of Seaways or Diamond and/or their respective affiliates for our own account and for the accounts of our customers and, accordingly, may at any time hold long or short positions in those securities. In addition, we may seek to, in the future, provide financial advisory and financing services to Seaways, Diamond or entities that are affiliated with Seaways or Diamond, for which we would expect to receive compensation. In addition, in the ordinary course of our business, we and our affiliates may trade or hold securities or financial instruments (including loans and other obligations) of Diamond, Seaways and/or their respective affiliates for our own account and for the accounts of our customers and, accordingly, may at any time hold long or short positions or otherwise effect transactions in those securities. Except as otherwise expressly provided in our engagement letter with Seaways, our opinion may not be used or referred to by Seaways, or quoted or disclosed to any person in any manner, without our prior written consent.

Based upon and subject to the foregoing, we are of the opinion that, as of the date hereof, the Exchange Ratio provided for in the Merger pursuant to the Merger Agreement is fair, from a financial point of view, to Seaways.

Very truly yours,

Board of Directors
Diamond S Shipping Inc.
33 Benedict Place, 2nd Floor
Greenwich, CT 06830

Members of the Board:

You have requested our opinion as to the fairness, from a financial point of view, to the holders of common shares, par value $0.001 per share (“Company Common Stock”), of Diamond S Shipping Inc. (the “Company”), other than International Seaways, Inc. (“International Seaways”) and its affiliates (collectively, the “Excluded Holders”), of the Exchange Ratio (as defined below) set forth in the Agreement and Plan of Merger (the “Agreement”) to be entered into by and among the Company, International Seaways and Dispatch Transaction Sub, Inc., a wholly owned subsidiary of International Seaways (the “Merger Sub”). As more fully described in the Agreement, Merger Sub will be merged with and into the Company (the “Transaction”) and each issued and outstanding share of Company Common Stock will be converted into the right to receive 0.55375 registered shares, without par value (“International Seaways Common Stock”), of International Seaways (the “Exchange Ratio”), subject to adjustment as specified in the Agreement (as to which we express no opinion). In addition, the Agreement contemplates (1) the termination, at the closing of the Transaction, of certain management and services agreements to which the Company is a party in accordance with a termination agreement to be entered into concurrently with the execution of the Agreement (the “Termination Agreement”), pursuant to which the Company will be required to make specified payments thereunder (collectively, the “CSM Termination Payment”) and (2) that International Seaways may declare and pay a special dividend in the amount of $31,500,000 prior to the closing of the Transaction to holders of International Seaways Common Stock (the “International Seaways Special Dividend”).

In arriving at our opinion, we have, among other things: (i) reviewed certain publicly available business and financial information relating to the Company and International Seaways; (ii) reviewed certain third-party vessel appraisals of the Company and International Seaways provided to us by the management of the Company and certain adjustments to be made to such appraisals as agreed by the Company and International Seaways in connection with a net asset value analysis (“Appraisal Adjustments”); (iii) reviewed certain internal information relating to the business, earnings, cash flow, assets, liabilities and prospects of the Company, including certain vessel sales, furnished to us by the Company, including financial forecasts for the Company provided to or discussed with us by the management of the Company (the “Company Projections”); (iv) reviewed certain internal information relating to the business, earnings, cash flow, assets, liabilities and prospects of International Seaways furnished to us by International Seaways, including financial forecasts for International Seaways provided to or discussed with us by the management of International Seaways (the “International Seaways Projections”); (v) reviewed estimates of management of International Seaways, as adjusted by the management of the Company, regarding cost savings and other synergies anticipated to result from the Transaction, including the amount and timing thereof (“Synergy Estimates”); (vi) reviewed certain information relating to the capitalization of the Company and International Seaways furnished to us by the Company and International Seaways, respectively; (vii) considered certain potential pro forma impacts of the Transaction on the combined company resulting from the Transaction; (viii) conducted discussions with members of the senior managements and representatives of the Company and International Seaways concerning the information described in clauses (i) through (vii) of this paragraph, as well as the business and prospects of the Company and International Seaways, generally; (ix) reviewed publicly available financial and stock market data of certain other companies in lines of business that we deemed relevant; (x) reviewed a draft of the Agreement made available to us on March 30, 2021 and a draft,

C-1

TABLE OF CONTENTS

dated March 30, 2021, of the Termination Agreement; (xi) participated in certain discussions and negotiations among representatives of the Company and International Seaways and their advisors; and (xii) conducted such other financial studies and analyses and took into account such other information as we deemed appropriate.

In connection with our review, we have, with your consent, relied on the information supplied to, discussed with or reviewed by us for purposes of this opinion being complete and accurate in all material respects. We have not assumed any responsibility for independent verification of, and we did not independently verify, any of such information. With your consent, we have relied upon, without independent verification, the assessment of the Company with respect to legal, tax, regulatory and accounting matters and have assumed that the Company has obtained advice as to such matters from appropriate professionals. With respect to the third-party vessel appraisals of the Company and International Seaways provided to us by the management of the Company and Appraisal Adjustments, at your direction, we have assumed, that they represent reasonable estimates regarding the matters covered thereby. With respect to the financial forecasts referred to above, including the Company Projections and the International Seaways Projections, we have assumed, at your direction, that they have been reasonably prepared on a basis reflecting the best currently available estimates and judgments of the management of the Company and International Seaways (as the case may be) as to the future performance of the Company and International Seaways, respectively. With respect to the Synergy Estimates, we have assumed, at your direction, that they have been reasonably prepared on a basis reflecting the best currently available estimates and judgments of the management of the Company as to the cost savings and other synergies anticipated to result from the Transaction (including the amount and timing thereof) and net of costs necessary to achieve such cost savings and other synergies. At your direction, we have assumed that the third-party vessel appraisals of the Company and International Seaways provided to us by the management of the Company (and the Appraisal Adjustments) and the financial forecasts referred to above, including the Company Projections, the International Seaways Projections, and the Synergy Estimates, are a reasonable basis upon which to evaluate the Company, International Seaways and the Transaction and at your direction we have relied upon such appraisals (and the Appraisal Adjustments) and financial forecasts for purposes of our analyses and this opinion. We express no views as to the reasonableness of any such appraisals, financial forecasts or other information or the assumptions on which they are based. In addition, with your consent, we have not made any independent evaluation or appraisal of any of the assets or liabilities (contingent, derivative, off-balance-sheet, or otherwise) of the Company or International Seaways, nor have we been furnished with any such evaluation or appraisal (other than the third-party vessel appraisals of the Company and International Seaways provided to us by the management of the Company and Appraisal Adjustments). With your consent, we have assumed that any adjustment to be made to the Exchange Ratio pursuant to the Agreement, including the adjustment provided for in the Agreement to account for a sale by International Seaways of certain specified interests or assets and the subsequent declaration and payment of a dividend to holders of International Seaways Common Stock of proceeds of such sale in an aggregate amount up to $25,000,000 (the “Sale Dividend”), would not be material to our analyses or this opinion.

Our opinion does not address the Company’s underlying business decision to effect the Transaction or the relative merits of the Transaction as compared to any alternative business strategies or transactions that might be available to the Company and does not address any legal, regulatory, tax or accounting matters. At your direction, we have not been asked to, nor do we, offer any opinion as to any terms of the Agreement or any aspect or implication of the Transaction, except for the fairness of the Exchange Ratio in the Transaction pursuant to the Agreement from a financial point of view to the holders of Company Common Stock (other than Excluded Holders). In that regard, our opinion does not address the fairness or reasonableness of the amount of the CSM Termination Payment, the International Seaways Special Dividend or the Sale Dividend. Our opinion also does not address the individual circumstances that may be applicable to any particular holder of Company Common Stock, including any discount or premium that may be attributable to any such holder’s interest for any reason, or the non-economic rights of any such holder arising from its interest in the shares or otherwise. We are also not expressing any opinion as to what the value of shares of International Seaways Common Stock actually will be when issued in the Transaction or the prices at which shares of Company Common Stock or International Seaways Common Stock may trade at any time. We have assumed that the shares of International Seaways Common Stock to be issued in the Transaction will be approved for trading on the New York Stock Exchange. In addition, for purposes of our analyses and this opinion we have at your direction assumed that the final executed form of the Agreement and the

C-2

TABLE OF CONTENTS

Termination Agreement will not differ in any material respect from the drafts that we have reviewed, that the Transaction (including the payment of the CSM Termination Payment and the International Seaways Special Dividend) will be consummated in accordance with its terms without any waiver or modification that would be material to our analysis, and that the parties to the Agreement will comply with all the material terms of the Agreement. We have assumed, with your consent, that all governmental, regulatory or other consents or approvals necessary for the completion of the Transaction will be obtained, except to the extent that would not be material to our analysis.

Our opinion is necessarily based on economic, monetary, market and other conditions as in effect on, and the information made available to us as of, the date hereof, and we assume no responsibility to update this opinion for developments occurring or coming to our attention after the date hereof.

We have acted as your financial advisor in connection with the Transaction and will receive a fee for our services, the principal portion of which is contingent upon the consummation of the Transaction. We also became entitled to receive a fee upon having substantially completed our work necessary to deliver this opinion, without regard to the conclusion reached herein. Our affiliates, employees, officers and partners may at any time own securities (long or short) of the Company and International Seaways. We have provided investment banking and other services to the Company unrelated to the Transaction and in the future may provide such services to the Company and International Seaways, and have received and may receive compensation for such services. In the past two years prior to the date hereof, we acted as a financial advisor to the Company in connection with a business combination completed in March 2019.

This opinion is for the use and benefit of the Board of Directors of the Company (solely in its capacity as such) in its evaluation of the Transaction. This opinion does not constitute a recommendation as to how any holder of securities should vote or act with respect to the Transaction or any other matter. This opinion does not address the fairness of the Transaction or any aspect or implication thereof to, or any other consideration of or relating to, the holders of any class of securities, creditors or other constituencies of the Company, other than the fairness of the Exchange Ratio in the Transaction pursuant to the Agreement from a financial point of view to the holders of Company Common Stock (other than Excluded Holders). In addition, we do not express any opinion as to the fairness of the amount or nature of any compensation to be received by any officers, directors or employees of any parties to the Transaction, or any class of such persons, relative to the Exchange Ratio or otherwise. This opinion was approved by a Moelis & Company LLC fairness opinion committee.

Based upon and subject to the foregoing, it is our opinion that, as the date hereof, the Exchange Ratio in the Transaction pursuant to the Agreement is fair from a financial point of view to the holders of Company Common Stock, other than Excluded Holders.

Very truly yours,

MOELIS & COMPANY LLC

“INSW Shares” shall mean registered shares of INSW, without par value.

“Permitted Transfer” shall mean, in each case, with respect to each Securityholder, so long as (a) such Transfer is in accordance with applicable Law and (b) such Securityholder is in compliance with this Agreement, any Transfer of Subject Securities by the Securityholder to an Affiliate of such transferring Securityholder, so long as such Affiliate, in connection with such Transfer, executes a joinder to this Agreement pursuant to which such Affiliate agrees to become a party to this Agreement and be subject to the restrictions applicable to such Securityholder and otherwise become a party for all purposes of this Agreement, including delivering the irrevocable proxy set forth in Section 5 hereof; provided that no such Transfer shall relieve the transferring Securityholder from its obligations under this Agreement, other than with respect to the Subject Securities transferred in accordance with the foregoing provision; provided further, such transferring Securityholder delivers notice of such Transfer pursuant to Section 10.

“Subject Securities” shall mean, collectively, with respect to each Securityholder, such Securityholder’s Existing Shares, together with any INSW Shares or other voting capital stock or other securities of INSW of which such Securityholder acquires beneficial ownership or record ownership on or after the date of this Agreement (including any New Shares) up to and including the record date for any meeting of the stockholders of INSW (whether annual or special) called with respect to attaining a Required Vote of stockholders (including any additional record dates established for any postponements of such meeting).

“Transfer” shall mean (i) any direct or indirect offer, sale, assignment, conveyance, exchange, encumbrance, pledge, hypothecation, disposition, loan or other transfer (whether by merger of the applicable Securityholder, by tendering into any tender or exchange offer, by testamentary disposition, by operation of law or otherwise), either voluntary or involuntary, (ii) entry into any Contract, option or other understanding with respect to any offer, sale, assignment, conveyance, exchange, encumbrance, pledge, hypothecation, disposition, loan or other transfer (whether by merger of the applicable Securityholder, by tendering into any tender or exchange offer, by testamentary disposition, by operation of law or otherwise), of any Subject Securities (or any security convertible or exchangeable into Subject Securities) or beneficial or record ownership or other interest in any Subject Securities, (iii) to otherwise grant, permit or suffer the creation of any Liens on any Subject Securities (other than those created by this Agreement or under applicable securities laws) or (iv) to commit or agree, directly or indirectly, to take any of the foregoing actions.

2. Agreement to Retain Subject Securities.

2.1 Transfer and Encumbrance of Subject Securities. Before the receipt of due approval of the Idaho Share Issuance by Idaho’s shareholders, each Securityholder (severally as to itself and not jointly) agrees (and agrees to cause each of its Affiliates to agree), with respect to any Subject Securities owned beneficially or of record by such Securityholder, not to (a) Transfer any such Subject Securities except pursuant to a Permitted Transfer or pursuant to the Merger and the transactions contemplated by the Merger Agreement or (b) deposit any such Subject Securities into a voting trust or enter into any agreement, arrangement or understanding with any Person to vote or give instructions inconsistent with this Section 2, including any rights to acquire, any granting of, options, rights of first offer or refusal,

or any voting agreement or arrangement with respect to such Securityholder’s Subject Securities, grant any proxy (except as otherwise provided herein) or power of attorney with respect thereto or commit or agree, directly or indirectly, to take any of the foregoing actions. Such Securityholder further agrees (and agrees to cause each of its Affiliates to agree) to authorize and request INSW to notify INSW’s transfer agent that there is a stop transfer order with respect to all of the Subject Securities and that this Agreement places limits on the voting of the Subject Securities; provided, however, that any such stop transfer order shall terminate upon the Expiration Time. For the avoidance of doubt, nothing in this Agreement will restrict any Securityholder from Transferring any INSW Shares following receipt of the Required Votes.

2.2 Acquisition of Additional Securities. Each Securityholder (severally as to itself and not jointly) agrees that any INSW Shares and other capital shares of INSW that such Securityholder purchases or otherwise acquires beneficial or record ownership of, or with respect to which such Securityholder otherwise acquires sole or shared voting power, following the execution of this Agreement and prior to the Expiration Time (the “New Shares”), shall constitute Subject Securities and be subject to the terms and conditions of this Agreement.

2.3 Unpermitted Transfers. Any Transfer or attempted or purported Transfer of any Subject Securities in violation of Section 2.1 shall be null and void ab initio.

3. Agreement to Vote and Approve. Until the Expiration Time, at every meeting of the stockholders of INSW (whether annual or special) called with respect to any of the following matters, and at every adjournment or postponement thereof, and on every action or approval by written consent of the stockholders of INSW with respect to any of the following matters, each Securityholder shall (and agrees to cause each of its Affiliates to), or shall cause (and agrees to cause each of its Affiliates to cause) the holder of record on any applicable record date to (including via proxy), vote the Subject Securities owned beneficially or of record by such Securityholder and/or Affiliate (or cause the holder of record on any applicable record date to vote (including via proxy) the Subject Securities owned beneficially or of record by such Securityholder and/or Affiliate): (a) in favor of (i) the Idaho Share Issuance and (ii) any other proposals reasonably requested by INSW in furtherance of the transactions contemplated by the Merger Agreement (including any changes to the governing documents of INSW or as proposed in connection with the Merger and the other transactions contemplated by the Merger Agreement), (b) in favor of any proposal to adjourn or postpone such meeting of the stockholders of INSW to a later date if there are not sufficient votes to adopt the Merger Agreement and/or if there are not sufficient shares present in person or by proxy at such meeting of the stockholders of INSW to constitute a quorum and (c) against (i) any merger agreement, merger, tender offer, exchange offer, sale of all or substantially all assets, recapitalization, reorganization, consolidation, share exchange, business combination, liquidation, dissolution or similar transaction or series of transactions involving INSW, any Subsidiary of INSW, and any other Person or Idaho Superior Proposal (as defined in the Merger Agreement) (other than the Merger Agreement and the Merger), (ii) any action, proposal, transaction or agreement that could reasonably be expected to result in a breach of any covenant, representation or warranty or any other obligation or agreement of INSW under the Merger Agreement or of such Securityholder under this Agreement, (iii) any action, proposal, transaction or agreement that could reasonably be expected to hinder, delay, postpone, inhibit, discourage, interfere with or adversely affect the timely consummation of the Merger and the other transactions contemplated by the Merger Agreement, or that would reasonably be expected to result in any condition to the consummation of the Merger as set forth in Article VII of the Merger Agreement not being satisfied, or dilute, in any material respect, the benefit of the transactions contemplated thereby to INSW or to the stockholders of INSW, (iv) any amendment to INSW’s articles of incorporation or by-laws and (v) any change in a majority of the board of directors of INSW (clauses (a) through (c), the “Required Votes”). Any such vote shall be cast, or consent shall be given, for purposes of this Section 3, in accordance with such procedures relating thereto as shall ensure that it is duly counted for purposes of determining that a quorum is present and for purposes of recording in accordance herewith the results of such vote or consent.

D-3

TABLE OF CONTENTS

provided, however, that nothing herein shall prevent such Securityholder from acting in such Securityholder’s capacity as an employee, officer or director of INSW or any Subsidiary of INSW, or taking any action in such capacity (including at the direction of the board of directors of INSW), but only in either such case as and to the extent permitted by Section 5.4 of the Merger Agreement.

5. Irrevocable Proxy. By execution of this Agreement, each Securityholder and its Affiliates (if applicable) do hereby irrevocably and unconditionally appoint and constitute DSSI or any designee thereof, until the Expiration Time (immediately after which time this proxy shall automatically be revoked), with full power of substitution and resubstitution, as such Securityholder’s or Affiliates’ (if applicable) true and lawful attorney-in-fact and irrevocable proxy, to the fullest extent of such Securityholder’s or Affiliates’ (if applicable) rights with respect to the Subject Securities owned beneficially or of record by such Securityholder or its respective Affiliates (if applicable), to vote (or consent pursuant to a written consent) and exercise all voting and related rights, sign or execute forms of proxy and/or such other deeds or documents (including under seal, if necessary or desirable) and to do such other acts and things as may be necessary (including, without limitation, the power to execute and deliver written consents) with respect to such Subject Securities owned or held by the Shareholder regarding the matters referred to in such Subject Securities as set forth in Section 3. Each Securityholder and its Affiliates (if applicable) intend this proxy to be irrevocable and coupled with an interest until the Expiration Time (at which time this proxy shall automatically be revoked) for all purposes and hereby represents that any proxies heretofore given with respect to its Subject Securities, if any, are revocable and hereby revokes any proxy previously granted by each Securityholder and its Affiliates (if applicable) with respect to its Subject Securities. This proxy is granted in consideration of DSSI entering into the Merger Agreement. Each Securityholder and its Affiliates (if applicable) hereby ratifies and confirms all actions that the proxies appointed hereunder may lawfully do or cause to be done in accordance with this Agreement. At any meeting of the Securityholders of INSW (whether annual or special) to which Section 3 is applicable, each Securityholder shall (and shall cause its Affiliates to), or shall direct (and shall cause its Affiliates to direct) the holder(s) of record of all of the Subject Securities of such Securityholder or Affiliate (if applicable) on any applicable record date to, appear, in person or by proxy, at each meeting or otherwise cause all of the Subject Securities of such Securityholder or Affiliate (if applicable) to be counted as present thereat for purposes of establishing a quorum. If for any reason any proxy granted herein is not irrevocable after it becomes effective, then the Securityholder granting such proxy agrees, until the Expiration Time, to vote the Subject Securities of such Securityholder in accordance with the Required Votes. The parties hereto agree that the foregoing is a voting agreement. This proxy shall be binding upon the heirs, estate, executors, personal representatives, successors and assigns of the Securityholder (including any transferee of any of the Subject Securities). Each Securityholder undertakes and agrees: (i) to indemnify the Attorney and against all actions, claims, demands, proceedings, costs, charges, expenses and other liabilities whatsoever which may be made against the Attorney or for which the Attorney may become liable by reason of acting pursuant to this power of attorney; and (ii) that the Attorney shall not be liable to the Securityholder for any loss or damage occurring as a result of any act or omission made by the Attorney by reason of acting pursuant to this power of attorney.

6. Representations and Warranties of the Securityholders. Each Securityholder (severally as to itself and not jointly) hereby represents and warrants to DSSI as follows:

6.1 Due Authority; Organization. Such Securityholder has all necessary corporate or similar power and authority to execute and deliver this Agreement and to perform such Securityholder’s obligations hereunder. If such Securityholder is an entity, the execution, delivery and performance of this Agreement by such Securityholder has been duly and validly authorized by all necessary action on the part of such Securityholder, and no other corporate proceedings on the part of such Securityholder are necessary to approve this Agreement or to consummate the transaction contemplated hereby, and such Securityholder is duly organized, validly existing and in good standing under the laws of its jurisdiction of organization. This Agreement has been duly and validly executed and delivered by such Securityholder and, assuming the due authorization, execution and delivery of this Agreement by DSSI, constitutes a legal, valid and binding obligation of such Securityholder, enforceable against such Securityholder in accordance with its terms (except to the extent that enforceability may be limited by bankruptcy, insolvency, reorganization, moratorium, fraudulent conveyance, or other laws of general application relating to or affecting the enforcement of creditors’ rights generally).

E-3

TABLE OF CONTENTS

is duly counted for purposes of determining that a quorum is present and for purposes of recording in accordance herewith the results of such vote or consent.

4. Agreement Not to Solicit. Until the Expiration Time, each Securityholder (severally as to itself and not jointly and solely in the Securityholder’s capacity as such) shall not, and shall not authorize or permit any Representative or Affiliate to act on such Securityholder’s behalf in order to, directly or indirectly, engage in any conduct in which DSSI is not permitted to engage by Section 5.3(a) of the Merger Agreement; provided, however, that nothing herein shall prevent such Securityholder from acting in such Securityholder’s capacity as an employee, officer or director of DSSI or any Subsidiary of DSSI, or taking any action in such capacity (including at the direction of the board of directors of DSSI), but only in either such case as and to the extent permitted by Section 5.3 of the Merger Agreement.

5. Irrevocable Proxy. By execution of this Agreement, each Securityholder and its Affiliates (if applicable) do hereby irrevocably and unconditionally appoint and constitute INSW or any designee thereof, until the Expiration Time (immediately after which time this proxy shall automatically be revoked), with full power of substitution and resubstitution, as such Securityholder’s or Affiliates’ (if applicable) true and lawful attorney-in-fact and irrevocable proxy, to the fullest extent of such Securityholder’s or Affiliates’ (if applicable) rights with respect to the Subject Securities owned beneficially or of record by such Securityholder or its respective Affiliates (if applicable), to vote (or consent pursuant to a written consent) and exercise all voting and related rights, sign or execute forms of proxy and/or such other deeds or documents (including, without limitation, the power to execute and deliver written consents) with respect to such Subject Securities owned or held by the Shareholder regarding the matters referred to in such Subject Securities as set forth in Section 3. Each Securityholder and its Affiliates (if applicable) intend this proxy to be irrevocable and coupled with an interest until the Expiration Time (at which time this proxy shall automatically be revoked) for all purposes and hereby represents that any proxies heretofore given with respect to its Subject Securities, if any, are revocable and hereby revokes any proxy previously granted by each Securityholder and its Affiliates (if applicable) with respect to its Subject Securities. This proxy is granted in consideration of INSW entering into the Merger Agreement. Each Securityholder and its Affiliates (if applicable) hereby ratifies and confirms all actions that the proxies appointed hereunder may lawfully do or cause to be done in accordance with this Section 5. At any meeting of the Securityholders of DSSI (whether annual or special) to which Section 3 is applicable, each Securityholder shall (and shall cause its Affiliates to), or shall direct (and shall cause its Affiliates to direct) the holder(s) of record of all of the Subject Securities of such Securityholder or Affiliate (if applicable) on any applicable record date to, appear, in person or by proxy, at each meeting or otherwise cause all of the Subject Securities of such Securityholder or Affiliate (if applicable) to be counted as present thereat for purposes of establishing a quorum. If for any reason any proxy granted herein is not irrevocable after it becomes effective, then the Securityholder granting such proxy agrees, until the Expiration Time, to vote the Subject Securities of such Securityholder in accordance with the Required Votes. The parties hereto agree that the foregoing is a voting agreement. This proxy shall be binding upon the heirs, estate, executors, personal representatives, successors and assigns of the Securityholder (including any transferee of any of the Subject Securities). Each Securityholder undertakes and agrees: (i) to indemnify the Attorney and against all actions, claims, demands, proceedings, costs, charges, expenses and other liabilities whatsoever which may be made against the Attorney or for which the Attorney may become liable by reason of acting in good faith pursuant to and in accordance with this power of attorney; and (ii) that the Attorney shall not be liable to the Securityholder for any loss or damage occurring as a result of any act or omission made by the Attorney by reason of acting in good faith pursuant to and in accordance with this power of attorney.

WHEREAS, concurrently with the execution and delivery of this Agreement, DSSI, certain Affiliates (as defined below) of CSM are entering into a Voting and Support Agreement (the “Voting Agreement”) and a Termination of Director Designation Agreement and Resale and Registration Rights Agreement (the “DDA Termination Agreement”);

WHEREAS, the parties intend that, subject to the consummation of the INSW Transaction Closing, upon the transition of the management services in accordance with the terms and subject to the conditions contained herein, the following agreements shall terminate:

Commercial Management Agreement, dated as of March 27, 2019, by and between DSSI and CSM (the “CMA”);

(ii)

Management and Services Agreement, dated as of March 27, 2019, by and between DSSI and CSM (the “MSA”); and

(iii)

each Technical Management Agreement, dated as of March 27, 2019, by and between certain DSSI vessel-owning subsidiaries and CSM (also referred to as Part II Shipman 2009 Standard Ship Management Agreement) (the “TMAs”, and collectively with the CMA and the MSA, the “Subject Agreements”).

WHEREAS, in connection with the termination of the Subject Agreements, the Parties wish to facilitate an orderly transfer of activities related to the Vessels on the terms and subject to the conditions set forth herein.

NOW, THEREFORE, in consideration of the premises and the mutual agreement and covenants set forth herein, and for other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, the Parties do hereby agree as follows:

ARTICLE I
DEFINITIONS

Capitalized terms used herein but not otherwise defined herein have the meanings set forth in the MSA. The following terms used herein have the following meanings:

G-1

TABLE OF CONTENTS

Section 1.1 ”Affiliates” means, with respect to any Person as at any particular date, any other Persons that directly or indirectly, through one or more intermediaries, are controlled by, control or are under common control with the person in question, and “Affiliate” means any one of them; provided, that, with respect to CSM, “Affiliates” shall in any event include Capital Maritime & Trading Corp., Crude Carriers Investments Corp. and Capital GP L.L.C; provided, further, that neither INSW nor any of its Affiliates shall be deemed Affiliates of DSSI or DSSI’s Affiliates for any purpose hereunder or under the Subject Agreements.

Section 1.2 ”Escrow Agreement” means the Escrow Agreement on customary and reasonable terms reflecting the escrow deposit and release provisions contemplated by this Agreement, to be entered into by DSSI, CSM and the Escrow Agent concurrently with the INSW Transaction Closing.

Section 1.3 ”Escrow Amount Adjustment” means the aggregate amount of the Ticking Fee multiplied by 0.12.

Section 1.4 ”Freight Earned” with respect to any period means all gross charter revenues generated by the applicable vessel during such period, established based on supporting documentation provided by DSSI and/or Newco as reasonably required by CSM. In the event that the relevant vessel’s new commercial manager is unwilling or unable to provide such vessel’s Freight Earned, DSSI or Newco and CSM shall agree on an alternate method of calculating the Freight Earned, which method shall, as nearly as possible, approximate the economic effect of the preceding sentence. Such alternative method shall be deemed the “Freight Earned” hereunder.

Section 1.5 ”Governmental Entity” means any court, arbitral tribunal, administrative agency or commission or other governmental or regulatory agency or authority or any securities exchange.

Section 1.6 ”Law” means any statute, law, ordinance, policy rule or regulation of any Governmental Entity and all judicial interpretations thereof.

Section 1.7 ”Representative” means with respect to any Person, such Person’s directors, managers, officers, employees, agents, attorneys, consultants, advisors, financing sources or other Persons acting on behalf of such Person.

Section 1.8 ”Surviving Provisions” means Sections 6.1(5) (first sentence only), 8.1 (solely with respect to periods prior to the Transition Completion), 9.3, 9.4, 16.1, 17 and 18 of the CMA, Sections 6 (subject to Schedule 2 to the MSA as amended pursuant to Section 3.5 of this Agreement), 9 (last sentence only), 10 (last sentence only), 11 and 15 of the MSA, Schedule 2 to the MSA (as amended pursuant to Section 3.5 of this Agreement) and Sections 17(b), 17(c), 17(d), 22(i), 22(j) and 23 of the TMAs.

Section 1.9 ”Termination Fee Adjustment” means the aggregate amount of the Ticking Fee multiplied by 0.88.

Section 1.10 “Ticking Fee” means USD 700,000 per month for each calendar month the Transition Period — Other Vessels will extend after May 31, 2021; provided, that if the Transition Period — Other Vessels will end prior to the last day of a calendar month, the amount of the Ticking Fee for such calendar month shall be pro rated based upon a 30 day calendar month. By way of example only, if the INSW Transaction Closing occurs on June 30, 2021, the Ticking Fee would equal USD 2,800,000, as the Transition Period — Other Vessels will end on September 30, 2021 (such date being 90 days after the INSW Transaction Closing), which constitutes a period of four months by which the Transition Period — Other Vessels will extend past May 31, 2021. In such example, the Termination Fee Adjustment would be USD 2,464,000 and the Escrow Amount Adjustment would be USD 336,000.

Section 1.11 “Transition Completion” means the first day on which all of the Vessels have been transitioned (including in terms of both technical management and commercial management) to a DSSI Manager in accordance with Article III.

Section 1.12 “Transition Period — Other Vessels” means the 90 day period commencing on the day of the INSW Transaction Closing.

TRANSITION

(a) With respect to each Vessel on a time charter as of the INSW Transaction Closing, from the date of the INSW Transaction Closing, CSM, DSSI and/or Newco will jointly approach (in a manner to be mutually agreed by CSM, DSSI and/or Newco) the time charterers to endeavor to agree to a change in technical management as soon as reasonably practicable and, as per the terms of the respective time charters, from CSM and/or its Affiliates to the manager(s) designated by DSSI and/or Newco (the

G-3

TABLE OF CONTENTS

“DSSI Manager”); provided, however, to the extent that an earlier transition cannot be agreed upon, then CSM shall technically manage such applicable Vessel to the end of the time charter pursuant to the Subject Agreements and, if necessary, for a period of time until a transition is reasonably practicable and to be effected at a port/place in each case as mutually agreed between Newco and CSM, each acting reasonably (taking into account ship management practices and any local restrictions due to the COVID-19 pandemic).

(b) Subject to Section 3.3, CSM will continue to provide commercial management services pursuant to the Subject Agreements until each Vessel on a time charter is transitioned to the DSSI Manager.

(c) CSM will provide (including, for the avoidance of doubt, if necessary after the completion of the transition to the DSSI Manager) the remaining support services outlined on Exhibit B attached hereto (the “Remaining Support Services”) for each Vessel on time charter related to the period under the commercial and technical management of CSM and/or its Affiliates pursuant to the Subject Agreements.

(d) For the avoidance of doubt, (x) the TMA may terminate with respect to a particular Vessel on a time charter prior to the CMA for such Vessel, but not vice versa and accordingly the transition of commercial management for a Vessel on a time charter may occur only simultaneously with or after the transition of technical management of such Vessel, and (y) the transition of each such Vessel on a time charter for all purposes of this Agreement shall be deemed complete only once both commercial and technical management have been transitioned pursuant to this Section 3.1.

Section 3.2 Transition Period — Other Vessels. Beginning on the date hereof, CSM and/or its Affiliates, DSSI and/or Newco shall use their respective reasonable best efforts to commence planning and coordination for the transition of commercial and technical management of the Vessels not on a time charter from CSM and/or its Affiliates to the DSSI Manager (the “Other Vessel Transition”), including by putting together a schedule for the handover of each Vessel not on a time charter at the earliest practical opportunity. For each such Vessel, notwithstanding anything to the contrary in the Subject Agreements, beginning on the INSW Transaction Closing, CSM and/or its Affiliates, DSSI and/or Newco shall use their respective reasonable best efforts to facilitate the Other Vessel Transition on the earliest practical date after the INSW Transaction Closing. CSM and/or its Affiliates shall deliver such Vessels to a port/place in each case as mutually agreed between DSSI and/or Newco and CSM, each acting reasonably (taking into account ship management practices and any local restrictions due to the COVID-19 pandemic) on or promptly after the date of the INSW Transaction Closing consistent with the applicable Vessel’s commercial obligations. CSM will provide (including, for the avoidance of doubt, if necessary after the Transition Completion) the Remaining Support Services for each Vessel not on time charter related to the period under the commercial and technical management of CSM and/or its Affiliates pursuant to the Subject Agreements. For the avoidance of doubt, the transition of commercial management and technical management of any given Vessel not on a time charter may be completed at different times and in different ports/places, and the transition of each such Vessel for all purposes of this Agreement shall be deemed complete only once both commercial and technical management have been transitioned pursuant to this Section 3.2.

Section 3.3 New Time Charters. CSM and/or its Affiliates shall not commit any Vessels to any new time charter business longer than three (3) months +/- (30 days) without the prior written consent of DSSI and INSW (such consent not to be unreasonably withheld or delayed); provided that the charters are with respect to vegetable oils only. If for whatever reason the Merger Agreement is terminated prior to the INSW Transaction Closing, DSSI shall immediately inform CSM and CSM will be at liberty to commit Vessels to time charter business as set forth in the CMA.

Section 3.4 Management Transition. CSM shall provide technical management and commercial management services with respect to each Vessel which it continues to manage pursuant to the terms of this Agreement in the ordinary course of business as per the Subject Agreements until the Transition Completion. CSM will provide (including, for the avoidance of doubt, if necessary after the Transition Completion) the Remaining Support Services and any services to be provided pursuant to the Surviving Provisions for each Vessel related to the period under the commercial and technical management of CSM and/or its Affiliates.

Section 3.6 Observers. From and after the date hereof, DSSI and/or Newco: (a) may place two (2) observers at their own cost and expense and liability, for familiarization purposes, on board each Vessel; and (b) shall have the right to retain two (2) members of the off-signing crew (if practicable and acceptable to the crew members) for familiarization purposes for thirty (30) days or one (1) voyage, whichever is shorter, and subject to any applicable local restrictions imposed as a result of the COVID-19 pandemic. The DSSI Manager shall cover all expenses associated with retention of up to two (2) members of the off-signing crew as aforesaid. The rights of DSSI and/or Newco under this Section 3.6 shall be subject to using commercially reasonable efforts consistent with industry standards to ensure that such observers are COVID-19 free, including, without limitation, providing negative COVID-19 test results within 72 hours prior to embarkation at the intended port, and providing CSM with evidence of appropriate isolation measures having been taken. Each of DSSI and/or Newco shall use reasonable best efforts to ensure that, after embarkation, the observers strictly adhere to the Vessel’s health and safety protocols relating to COVID-19 at all times, which shall include, without limitation, submitting daily temperature readings and wearing face masks, and if requested by the Vessel’s master, immediately self-isolating should they show symptoms or signs of infection. These observers shall be on board of a Vessel for the purpose of familiarization and in the capacity of observers only, and they shall not interfere in any respect with the operation of the Vessel. The observers shall sign the P&I Club’s standard letter of indemnity prior to their embarkation and at all times adhere to the Vessel’s master orders. Promptly following completion of the transition of the relevant Vessel, DSSI and/or Newco, as the case may be, shall reimburse Capital for Capital’s reasonable, documented out-of-pocket costs associated with providing meals and sundry to such observers for the period during which they were on board the relevant Vessel, to the extent such costs are not allocated to Capital under the Subject Agreements.

Section 3.7 Insurance. CSM and/or its Affiliates shall make available, at the sole cost and expense of DSSI and/or Newco, all historical records and provide reasonable clarifications and support as required by DSSI and/or Newco on all (i) open claims in respect of each Vessel that arose during the period of DSSI’s and/or Newco’s ownership of such Vessel until such open claim has been closed and (ii) closed claims in respect of each Vessel during the period of DSSI’s and/or Newco’s ownership of such Vessel.

Section 3.8 Management of Additional Vessels and Replacements Provision.

The Parties agree that, in addition to the Termination Fee and any other payment to CSM pursuant to this Agreement, subject to the occurrence of the INSW Transaction Closing, DSSI shall pay, or cause to be paid to CSM, in each case by wire transfer of immediately available funds promptly following the INSW Transaction Closing (provided that all fees set forth below payable in respect of the calendar month in which the INSW Transaction Closing takes place (the “Closing Month”), shall be payable on or prior to the last day of the calendar month following the Closing Month) the following (collectively, the “Section 8 Amount”):

(a)

Upon payment of the Section 8 Amount to CSM, Section 8 of the MSA shall be null and void and of no further force or effect. In the event this Agreement is terminated pursuant to the first sentence of Section 8.1, DSSI shall (i) work in good faith to replace the M/T Aias and the M/T Amoureux with Other Vessels or Additional Vessels (as such terms are defined in the MSA) within three (3) months of the termination and (ii) pay to CSM the amounts specified in paragraphs (a) and (b) of this Section 3.8, as applicable, until the replacement of the applicable vessel.

Section 8.6 Law and Arbitration. This Agreement shall be governed by the laws of England. Any dispute under this Agreement shall be referred to arbitration in London in accordance with the Arbitration Act 1996 or any statutory modification or re-enactment then in force. The arbitration shall be conducted in accordance with the London Maritime Arbitrators’ Association (LMAA) Terms current at the time when the arbitration is commenced.

Save as after mentioned, the reference shall be to three arbitrators, one to be appointed by each Party and the third by the two arbitrators so appointed. A Party wishing to refer a dispute to arbitration shall appoint its arbitrator and send notice of such appointment to the other Party requiring the other party to appoint its arbitrator within 14 calendar days of that notice and stating that it will appoint its arbitrator as sole arbitrator unless the other Party appoints its own arbitrator and gives notice that it has done so within the 14 calendar days specified.
