Unless expressly incorporated into this Registration Statement, documents or information deemed to have been furnished and not filed in accordance with the rules of the Commission prior or subsequent to the date hereof shall not be incorporated by reference into this Registration Statement.

Item 5. Interests of Named Experts and Counsel.

As of the date of this Registration Statement, attorneys of Fenwick & West LLP beneficially own an aggregate of approximately 32 shares of the Registrant’s common stock.

Item 6. Indemnification of Directors and Officers.

The Registrant is incorporated under the laws of the State of Delaware. Section 145 of the Delaware General Corporation Law (the “DGCL”) authorizes a court to award, or a corporation’s board of directors to grant, indemnity to directors and officers under certain circumstances and subject to certain limitations. The terms of Section 145 of the DGCL are sufficiently broad to permit indemnification under certain circumstances for liabilities, including reimbursement of expenses incurred, arising under the Securities Act of 1933, as amended (the “Securities Act”).

As permitted by the DGCL, the Registrant’s restated certificate of incorporation contains provisions that limit the liability of its directors for monetary damages to the fullest extent permitted by the DGCL for any breach of fiduciary duties as a director, except liability for the following:

II-2

As permitted by the DGCL, the Registrant’s restated bylaws provide that:

In addition, the Registrant has entered into indemnity agreements with each of its current directors and executive officers. These agreements provide for the indemnification of directors and executive officers for all reasonable expenses and liabilities incurred in connection with any action or proceeding brought against them by reason of the fact that they are or were agents of the Registrant.

The Registrant currently carries liability insurance for its directors and executive officers for securities matters.

Item 7. Exemption from Registration Claimed.

Not applicable.

Item 8. Exhibits.

II-3

Item 9. Undertakings.

A. The undersigned Registrant hereby undertakes: (1) to file, during any period in which offers or sales are being made, a post-effective amendment to this Registration Statement: (i) to include any prospectus required by Section 10(a)(3) of the Securities Act; (ii) to reflect in the prospectus any facts or events arising after the effective date of the Registration Statement (or the most recent post-effective amendment thereof) which, individually or in the aggregate, represent a fundamental change in the information set forth in this Registration Statement — notwithstanding the foregoing, any increase or decrease in volume of securities offered (if the total dollar value of securities offered would not exceed that which was registered) and any deviation from the low or high end of the estimated maximum offering range may be reflected in the form of prospectus filed with the Commission pursuant to Rule 424(b) if, in the aggregate, the changes in volume and price represent no more than a 20 percent change in the maximum aggregate offering price set forth in the “Calculation of Filing Fee Tables” in the effective Registration Statement; and (iii) to include any material information with respect to the plan of distribution not previously disclosed in the Registration Statement or any material change to such information in the Registration Statement; provided, however, that clauses (1)(i) and (1)(ii) do not apply if the information required to be included in a post-effective amendment by those clauses is contained in reports filed with or furnished to the Commission by the Registrant pursuant to Section 13 or Section 15(d) of the Exchange Act that are incorporated by reference in this Registration Statement; (2) that, for the purpose of determining any liability under the Securities Act, each such post-effective amendment shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof; and (3) to remove from registration by means of a post-effective amendment any of the securities being registered which remain unsold at the termination of the offering.

B. The undersigned Registrant hereby undertakes that, for purposes of determining any liability under the Securities Act, each filing of the Registrant’s annual report pursuant to Section 13(a) or Section 15(d) of the Exchange Act (and, where applicable, each filing of an employee benefit plan’s annual report pursuant to section 15(d) of the Exchange Act) that is incorporated by reference into this Registration Statement shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.

C. Insofar as indemnification for liabilities arising under the Securities Act may be permitted to directors, officers and controlling persons of the Registrant pursuant to the indemnification provisions summarized in Item 6, or otherwise, the Registrant has been advised that in the opinion of the Commission such indemnification is against public policy as expressed in the Securities Act and is, therefore, unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment by the Registrant of expenses incurred or paid by a director, officer or controlling person of the Registrant in the successful defense of any action, suit or proceeding) is asserted by such director, officer or controlling person in connection with the securities being registered, the Registrant will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question whether such indemnification by it is against public policy as expressed in the Securities Act and will be governed by the final adjudication of such issue.

SECTION 5. SHARES SUBJECT TO PLAN AND SHARE LIMITS.

SECTION 6. TERMS AND CONDITIONS OF OPTIONS.

(a) Stock Option Agreement. Each Grant of an Option under the Plan shall be evidenced and governed exclusively by a Stock Option Agreement between the Optionee and the Company. Such Option shall be subject to all applicable terms and conditions of the Plan and may be subject to any other terms and conditions that are not inconsistent with the Plan and that the Committee deems appropriate for inclusion in a Stock Option Agreement (including without limitation any performance conditions). The provisions of the various Stock Option Agreements entered into under the Plan need not be identical.

(b) Number of Shares. Each Stock Option Agreement shall specify the number of Shares that are subject to the Option and shall be subject to adjustment of such number in accordance with Section 9.

(c) Exercise Price. An Option’s Exercise Price shall be established by the Committee and set forth in a Stock Option Agreement. The Exercise Price of an Option shall not be less than 100% of the Fair Market Value on the date of Grant.

(d) Exercisability and Term. Each Stock Option Agreement shall specify the date when all or any installment of the Option is to become exercisable. The Stock Option Agreement shall also specify the term of the Option; provided that the term of an Option shall in no event exceed ten years from the date of Grant. Unless the applicable Stock Option Agreement provides otherwise, each Option shall vest and become exercisable with respect to 20% of the Shares subject to the Option upon completion of one year of Service measured from the vesting commencement date, the balance of the Shares subject to the Option shall vest and become exercisable in forty-eight equal installments upon completion of each month of Service thereafter, and the term of the Option shall be ten years from the date of Grant. A Stock Option Agreement may provide for accelerated vesting in the event of the Participant’s death, Disability, or other events. Notwithstanding any other provision of the Plan, no Option can be exercised after the expiration date provided in the applicable Stock Option Agreement and no Option may provide that, upon exercise of the Option, a new Option will automatically be granted.

(e) Modifications of Options. Within the limitations of the Plan, the Committee may modify outstanding Options, provided that, unless a modification is necessary or desirable to comply with any applicable law, regulation or rule, such modification of an Option shall not, without the consent of the Optionee, impair his or her rights or obligations under such Option.

-6-

(f) Assignment or Transfer of Options. Except as otherwise provided in the applicable Stock Option Agreement and then only to the extent permitted by applicable law, no Option shall be transferable by the Optionee other than by will or by the laws of descent and distribution. For the avoidance of doubt, in no event may an Option be transferred for value and any Option transferred in accordance with a Stock Option Agreement, if permitted, shall continue to be subject to the same terms and conditions as were applicable to the Option immediately before the transfer. Except as otherwise provided in the applicable Stock Option Agreement, an Option may be exercised during the lifetime of the Optionee only by the Optionee or by the guardian or legal representative of the Optionee. No Option or interest therein may be assigned, pledged or hypothecated by the Optionee during his or her lifetime, whether by operation of law or otherwise, or be made subject to execution, attachment or similar process.

SECTION 7. PAYMENT FOR OPTION SHARES.

The entire Exercise Price of Shares issued upon exercise of Options shall be payable in cash at the time when such Shares are purchased, except as follows and only if so provided for in an applicable Stock Option Agreement:

(a) Surrender of Stock. Payment for all or any part of the Exercise Price may be made with Shares which have already been owned by the Optionee; provided that the Committee may, in its sole discretion, require that Shares tendered for payment be previously held by the Optionee for a minimum duration. Such Shares shall be valued at their Fair Market Value.

(b) Cashless Exercise. Payment for all or any part of the Exercise Price may be made through Cashless Exercise at the Committee’s sole discretion.

(c) Other Forms of Payment. Payment for all or any part of the Exercise Price may be made in any other form that is consistent with applicable laws, regulations and rules and approved by the Committee.

The Stock Option Agreement may specify that payment may be made in any form(s) described in this Section 7.

SECTION 8. TERMS AND CONDITIONS OF STOCK UNITS.

(a) Stock Unit Agreement. Each grant of Stock Units under the Plan shall be evidenced and governed exclusively by a Stock Unit Agreement between the Specified Individual and the Company. Such Stock Units shall be subject to all applicable terms and conditions of the Plan and may be subject to any other terms and conditions that are not inconsistent with the Plan and that the Committee deems appropriate for inclusion in the applicable Stock Unit Agreement (including without limitation any performance conditions). The provisions of the various Stock Unit Agreements entered into under the Plan need not be identical. Stock Units may be granted in consideration of a reduction in the Specified Individual’s other compensation.

(b) Number of Shares. Each Stock Unit Agreement shall specify the number of Shares to which the Stock Unit Grant pertains and shall be subject to adjustment of such number in accordance with Section 9.

(c) Payment for Stock Units. Stock Units shall be issued without consideration.

(d) Vesting Conditions. Unless the applicable Stock Unit Agreement provides otherwise, each Stock Unit shall vest with respect to 25% of the Shares subject to the Stock Unit upon completion of each year of Service on each of the first through fourth annual anniversaries of the vesting commencement date.

(e) Voting and Dividend Rights. The holders of Stock Units shall have no voting or dividend rights.

(f) Form and Time of Settlement of Stock Units. Settlement of vested Stock Units may be made in the form of (i) cash, (ii) Shares or (iii) any combination of both, as determined by the Committee at the time of grant of the Stock Units, in its sole discretion. Methods of converting Stock Units into cash may include (without limitation) a method based on the average Fair Market Value of Shares over a series of trading

-7-

days. Vested Stock Units may be settled in a lump sum or in installments. The distribution may occur or commence when the vesting conditions applicable to the Stock Units have been satisfied or have lapsed, in accordance with applicable law, to any later date. Until an Award of Stock Units is settled, the number of such Stock Units shall be subject to adjustment pursuant to Section 9.

(g) Creditors’ Rights. A holder of Stock Units shall have no rights other than those of a general creditor of the Company. Stock Units represent an unfunded and unsecured obligation of the Company, subject to the terms and conditions of the applicable Stock Unit Agreement.

(h) Modification or Assumption of Stock Units. Within the limitations of the Plan, the Committee may modify or assume outstanding stock units or may accept the cancellation of outstanding stock units (including stock units granted by another issuer) in return for the grant of new Stock Units for the same or a different number of Shares and with the same or different vesting provisions. Notwithstanding the preceding sentence or anything to the contrary herein, the Committee may not modify an outstanding Stock Unit such that the modification shall, without the consent of the Participant, impair his or her rights or obligations under such Stock Unit, unless such modification is necessary or desirable to comply with any applicable law, regulation or rule.

(i) Assignment or Transfer of Stock Units. Except as provided in the applicable Stock Unit Agreement and then only to the extent permitted by applicable law, Stock Units shall not be anticipated, assigned, attached garnished, optioned, transferred or made subject to any creditor’s process, whether voluntarily, involuntarily or by operation of law. Any act in violation of this Section 8(i) shall be void. However, this Section 8(i) shall not preclude a Specified Individual from designating a beneficiary who will receive any outstanding vested Stock Units in the event of the Specified Individual’s death, nor shall it preclude a transfer of vested Stock Units by will or by the laws of descent and distribution.

SECTION 9. PROTECTION AGAINST DILUTION.

(a) Adjustments. In the event of a subdivision of the outstanding Shares, a declaration of a dividend payable in Shares, a declaration of a dividend payable in a form other than Shares in an amount that has a material effect on the price of Shares, a combination or consolidation of the outstanding Shares (by reclassification or otherwise) into a lesser number of Shares, a recapitalization, a spin-off or a similar occurrence, the Committee shall make appropriate adjustments to the following:

(i) the number of Shares and the kind of shares or securities available for future Awards under Section 5;

(ii) the number of Shares and the kind of shares or securities covered by each outstanding Award;

(iii) or the Exercise Price under each outstanding Option;

provided, however, that the Committee will make such adjustments to an Award required by Section 25102(o) of the California Corporations Code to the extent the Company is relying upon the exemption afforded thereby with respect to the Award.

(b) Participant Rights. Except as provided in this Section 9, a Participant shall have no rights by reason of any issue by the Company of stock of any class or securities convertible into stock of any class, any subdivision or consolidation of shares of stock of any class, the payment of any stock dividend or any other increase or decrease in the number of shares of stock of any class. If by reason of an adjustment pursuant to this Section 9 a Participant’s Award covers additional or different shares of stock or securities, then such additional or different shares and the Award in respect thereof shall be subject to all of the terms, conditions and restrictions which were applicable to the Award and the Shares subject to the Award prior to such adjustment.

-8-

(c) Fractional Shares. Any adjustment of Shares pursuant to this Section 9 shall be rounded down to the nearest whole number of Shares. Under no circumstances shall the Company be required to authorize or issue fractional shares and no consideration shall be provided as a result of any fractional shares not being issued or authorized.

SECTION 10. EFFECT OF A CORPORATE TRANSACTION.

(a) Corporate Transaction. In the event that the Company is a party to a Corporate Transaction, outstanding Awards shall be subject to the applicable agreement of merger, reorganization, or sale of assets. Such agreement may provide, without limitation, for the assumption or substitution of outstanding Options or Stock Units by the surviving corporation or its parent, for the replacement of outstanding Options and Stock Units with a cash incentive program of the surviving corporation which preserves the spread existing on the unvested portions of such outstanding Awards at the time of the transaction and provides for subsequent payout in accordance with the same vesting provisions applicable to those Awards, or for the cancellation of outstanding Options and/or Stock Units, with or without consideration, in all cases without the consent of the Participant.

(b) Termination. Immediately following the consummation of a Corporate Transaction, all outstanding Options and Stock Units shall terminate and cease to be outstanding, except to the extent that they are assumed by the surviving corporation or its parent.

(c) Dissolution. To the extent not previously exercised or settled, Options and Stock Units shall terminate immediately prior to the dissolution or liquidation of the Company.

SECTION 11. LIMITATIONS ON RIGHTS.

(a) No Entitlements. A Participant’s rights, if any, in respect of or in connection with any Award is derived solely from the discretionary decision of the Company to permit the individual to participate in the Plan and to benefit from a discretionary Award. By accepting an Award under the Plan, a Participant expressly acknowledges that there is no obligation on the part of the Company to continue the Plan and/or grant any additional Awards. Any Award granted hereunder is not intended to be compensation of a continuing or recurring nature, or part of a Participant’s normal or expected compensation, and in no way represents any portion of a Participant’s salary, compensation, or other remuneration for purposes of pension benefits, severance, redundancy, resignation or any other purpose.

Neither the Plan nor any Award granted under the Plan shall be deemed to give any individual a right to remain an employee, consultant or director of the Company, a Parent, a Subsidiary or an Affiliate. The Company and its Parents and Subsidiaries and Affiliates reserve the right to terminate the Service of any person at any time, and for any reason, subject to applicable laws, the Company’s Articles of Incorporation and Bylaws and a written employment agreement (if any), and such terminated person shall be deemed irrevocably to have waived any claim to damages or specific performance for breach of contract or dismissal, compensation for loss of office, tort or otherwise with respect to the Plan or any outstanding Award that is forfeited and/or is terminated by its terms or to any future Award.

(b) Stockholders’ Rights. A Participant shall have no dividend rights, voting rights or other rights as a stockholder with respect to any Shares covered by his or her Award prior to the issuance of such Shares (as evidenced by an appropriate entry on the books of the Company or a duly authorized transfer agent of the Company). No adjustment shall be made for cash dividends or other rights for which the record date is prior to the date when such Shares are issued, except as expressly provided in Section 9.

(c) Regulatory Requirements. Any other provision of the Plan notwithstanding, the obligation of the Company to issue Shares or other securities under the Plan shall be subject to all applicable laws, rules and regulations and such approval by any regulatory body as may be required. The Company reserves the right to restrict, in whole or in part, the delivery of Shares or other securities pursuant to any Award prior to the satisfaction of all legal requirements relating to the issuance of such Shares or other securities, to their registration, qualification or listing or to an exemption from registration, qualification or listing.

-9-

SECTION 12. WITHHOLDING TAXES.

(a) General. A Participant shall make arrangements satisfactory to the Company for the satisfaction of any withholding tax obligations that arise in connection with his or her Award. The Company shall not be required to issue any Shares or make any cash payment under the Plan until such obligations are satisfied.

(b) Share Withholding. If a public market for the Company’s Shares exists, the Committee may permit a Participant to satisfy all or part of his or her withholding or income tax obligations by having the Company withhold all or a portion of any Shares that otherwise would be issued to him or her or by surrendering or attesting to all or a portion of any Shares that he or she previously acquired. Such Shares shall be valued based on the value of the actual trade or, if there is none, the Fair Market Value as of the previous day. Any payment of taxes by assigning Shares to the Company may be subject to restrictions, including, but not limited to, any restrictions required by rules of the SEC. The Committee may, in its discretion, also permit a Participant to satisfy withholding or income tax obligations related to an Award through Cashless Exercise or through a sale of Shares underlying the Award.

SECTION 13. DURATION AND AMENDMENTS.

(a) Term of the Plan. The Plan shall become effective upon its approval by Board, subject to the approval of the Company’s stockholders in compliance, when required, with Section 260.140.41(g) of Title 10 of the California Code of Regulations. The Plan shall terminate on the tenth anniversary of the date of approval by the Company’s stockholders and may be terminated on any earlier date pursuant to this Section 13.

(b) Right to Amend or Terminate the Plan. The Board may amend or terminate the Plan at any time and for any reason. The termination of the Plan, or any amendment thereof, shall not impair the rights or obligations of any Participant under any Award previously granted under the Plan without the Participant’s consent, unless such modification is necessary or desirable to comply with any applicable law, regulation or rule. No Awards shall be granted under the Plan after the Plan’s termination. An amendment of the Plan shall be subject to the approval of the Company’s stockholders only to the extent such approval is otherwise required by applicable laws, regulations or rules.

Exhibit 99.2

United States Holders

CISCO SYSTEMS, INC.

RESTRICTED STOCK UNIT ASSUMPTION AGREEMENT

Dear [Field: Full Name]:

As you know, on January 31, 2025 (the “Closing Date”), Cisco Systems, Inc. (“Cisco”) acquired Threatology, Inc. (“Company”) (the “Acquisition”), pursuant to the Agreement and Plan of Merger by and among Cisco, the Company and certain other parties dated on or about December 15, 2024 (the “Acquisition Agreement”). On the Closing Date, you held one or more outstanding restricted stock units related to shares of Company common stock that were previously granted to you under the Company 2025 Equity Incentive Plan (the “Plan”). Pursuant to the Acquisition Agreement, on the Closing Date, Cisco assumed Company’s obligations to honor each of your restricted stock unit award(s) related to shares of Company common stock granted to you under the Plan (the “Company RSU(s)”) and documented by a restricted stock unit agreement(s) and any amendment(s) entered into by and between you and Company (collectively, the “RSU Agreement(s)”) and such Company RSU(s) were accordingly assumed by Cisco (the “Assumed RSU(s)”) to be settleable for a number of shares of Cisco common stock. This Restricted Stock Unit Assumption Agreement (the “Agreement”) evidences the terms of the assumption of your Company RSU(s), including the necessary adjustments for assumption of the Company RSU(s) that are required by the Acquisition.

The table below summarizes your Company RSU(s) immediately before and after the Acquisition:

Grant Details

The post-Acquisition adjustments are based on the Equity Exchange Ratio of 0.0518104076, as determined in accordance with the terms of the Acquisition Agreement, and are intended to preserve immediately after the Acquisition the aggregate fair market value of the underlying shares immediately prior to the Acquisition. The number of shares of Cisco common stock subject to your Assumed RSU(s) was determined by multiplying the Equity Exchange Ratio by the number of shares of Company common stock remaining subject to your Company RSU(s) on the Closing Date and rounding the resulting product down to the next whole number of shares of Cisco common stock.

Unless the context otherwise requires, for purposes of this Agreement, any references in the Plan and the RSU Agreement(s) to: (i) the “Company” or the “Corporation” means Cisco, (ii) “Stock,” “Common Stock,” “Shares” or “Ordinary Shares” means shares of Cisco common stock, (iii) the “Board of Directors” or the “Board” means the Board of Directors of Cisco and (iv) the “Committee” means the Compensation and Management Development Committee of the Board of Directors of Cisco. As used in this Agreement, “employer” means your actual employer. All references in the RSU Agreement(s) and the Plan relating to your status as an employee or consultant of Company or a subsidiary or affiliate will now refer to your status as an employee or consultant of Cisco or any present or future Cisco parent, subsidiary or affiliate.

United States Holders

The vesting commencement date, vesting schedule and expiration date of your Assumed RSU(s) remain the same as set forth in the RSU Agreement(s) and/or any notice of grant but with the number of shares subject to each vesting installment adjusted to reflect the effect of the Acquisition. (In this respect, please note that any discussion of terms in any employment offer letter (whether from Cisco, Company or any other related employer) is explanatory in nature and will not result in duplication of benefits (including vesting) with respect to your Assumed RSU(s).) Vesting of your Assumed RSU(s) may be suspended, or your Assumed RSUs may be pro-rated, during a leave of absence in accordance with your RSU Agreement(s) and Cisco’s policies. Cisco will withhold applicable taxes by withholding vested Cisco shares that would otherwise be released under the assumed Company RSU on the vest date. The amount of Cisco shares withheld will be equal in value to the amount necessary to satisfy any such withholding tax obligation. All other provisions which govern either the settlement or the termination of your Assumed RSU(s) remain the same as set forth in the RSU Agreement(s), and the provisions of the RSU Agreement(s), will govern and control your rights under this Agreement to acquire shares of Cisco common stock, except as expressly modified by this Agreement, the Acquisition Agreement or otherwise in connection with the Acquisition.

UNLESS EXPRESSLY SET FORTH IN AN EMPLOYMENT AGREEMENT OR OFFER LETTER WITH CISCO, UPON TERMINATION OF YOUR EMPLOYMENT WITH CISCO OR ANY PRESENT OR FUTURE CISCO SUBSIDIARY, ALL UNVESTED RESTRICTED STOCK UNITS SHALL BE IMMEDIATELY FORFEITED WITHOUT CONSIDERATION, EXCEPT AS MAY BE OTHERWISE DETERMINED BY CISCO IN ITS SOLE DISCRETION.

Nothing in this Agreement or the RSU Agreement(s) interferes in any way with your right and the right of Cisco or any parent, subsidiary or affiliate, which rights are expressly reserved, to terminate your employment at any time for any reason, subject to applicable law. Future restricted stock units, if any, you may receive from Cisco will be governed by the terms of the Cisco equity plan under which such restricted stock units are granted, and such terms may be different from the terms of your Assumed RSU(s), including, but not limited to, vesting and forfeiture upon your termination of employment.

Until Cisco’s Stock Administration Department is in receipt of your understanding and acceptance of this Agreement (which can be accomplished electronically by following the instructions under the heading of Acknowledgment below) your Cisco account will not be activated and your Assumed RSU(s) will not be settled. Notwithstanding the forgoing, if you do not accept this Agreement prior to the first vesting date of the Assumed RSUs that occurs on or after the Closing Date, your Award will be automatically accepted on your behalf on such first vesting date.

If you have any questions regarding this Agreement or your Assumed RSU(s), please contact mastockinquiries@cisco.com.
