The Board of Directors knows of no other business that will come before the 2024 Annual Meeting of Stockholders.

The Notice of our 2024 Annual Meeting of Stockholders, this Proxy Statement, and a proxy card, together with our Annual Report on Form 10-K for the year ended December 31, 2023, are being mailed to our stockholders on or about September [●], 2024. Such annual report, which includes our audited financial statements, is not to be regarded as proxy solicitation material. We will bear the cost of our solicitation of proxies. The original solicitation of proxies by mail may be supplemented by personal interview, telephone, or facsimile by our directors, officers, or employees, who will receive no additional compensation for such services. Arrangements will be made with brokerage houses and other custodians, nominees, and fiduciaries for the forwarding of solicitation material to the beneficial owners of stock held by any such persons, and we will reimburse those custodians, nominees, and fiduciaries for the reasonable out-of-pocket expenses incurred by them in doing so.

The Board of Directors is soliciting votes (1) FOR each of the four (4) nominees for director named herein for election to the Company’s Board of Directors (“Proposal 1”); (2) FOR the ratification of the appointment of BDO USA, P.C. as the Company’s independent registered public accounting firm for the year ending December 31, 2024 (“Proposal 2”); (3) FOR the approval of amendments to the Company’s 2020 Stock Incentive Plan (the “Stock Incentive Plan Amendment”) to increase the number of shares of Common Stock that the Company will have authority to grant under the plan from 280,000 shares to 2,500,000 shares and to amend the annual non-employee director grant limit to 250,000 shares of common stock (the “Stock Incentive Plan Amendment Proposal” or “Proposal 3”); (4) FOR the approval of an amendment to the Articles of Incorporation, as amended (the “Articles of Incorporation”), to at the discretion of the Board of Directors of the Company, effect an increase in the number of authorized shares of Common Stock from 14,000,000 shares to 350,000,000 shares (the “Authorized Common Stock Increase Proposal” or “Proposal 4”), such amendment to be effected after stockholder approval thereof only in the event the Board of Directors still deems it advisable; and (5) FOR approval of an adjournment of the 2024 Annual Meeting of Stockholders to a later date or dates, if necessary or appropriate, to permit further solicitation and vote of proxies in the event there are not sufficient votes in favor of the Stock Incentive Plan Amendment Proposal and/or the Authorized Common Stock Increase Proposal (the “Adjournment Proposal” or “Proposal 5”).

A: The Board of Directors recommends that you vote your shares: (1) FOR each of the four (4) nominees named herein for election to the Company’s Board of Directors; (2) FOR the ratification of the appointment of BDO USA, P.C. as our independent registered public accounting firm for the year ending December 31, 2024; (3) FOR the approval of amendments to the Company’s 2020 Stock Incentive Plan (to increase the number of shares of Common Stock that the Company will have authority to grant under the plan from 280,000 shares to 2,500,000 shares and to amend the annual non-employee director grant limit to 250,000 shares of common stock ; (4) FOR the approval of an amendment to the Company’s Articles of Incorporation, to, at the discretion of the Board of Directors of the Company, effect an increase in the number of authorized shares of Common Stock from 14,000,000 shares to 350,000,000 shares, such amendment to be effected after stockholder approval thereof only in the event the Board of Directors still deems it advisable; and (5) FOR approval of the adjournment the 2024 Annual Meeting of Stockholders to a later date or dates, if necessary or appropriate, to permit further solicitation and vote of proxies in the event that there are insufficient votes for, or otherwise in connection with, the approval of Proposal 3 and/or Proposal 4.

Q: Who is entitled to vote?

A: Only stockholders who own our Common Stock as of the close of business on September 27, 2024 (the “Record Date”) will be entitled to vote at the 2024 Annual Meeting of Stockholders.

A: On the Record Date, (i) 1,353,862 shares of Common Stock were issued and outstanding1 All share numbers of Common Stock have been adjusted to reflect the 1-for-25 reverse stock split effected August 26, 2024.

Only holders of record of our Common Stock as of the close of business on the Record Date will be entitled to notice of and to vote at the 2024 Annual Meeting of Stockholders and at any adjournments or postponements thereof, with each share being entitled to one vote on each matter.

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

A: Most of our stockholders hold their shares through a broker or other nominee rather than directly in their own name. As summarized below, there are some distinctions between shares held of record and those owned beneficially. If your shares are registered directly in your name with our transfer agent, Equiniti Group plc (formerly Corporate Stock Transfer, Inc.), you are considered, with respect to those shares, the stockholder of record and these proxy materials are being sent directly to you by us. As the stockholder of record, you have the right to grant your voting proxy directly to Mr. Steven Shallcross, our Chief Executive Officer, Chief Financial Officer and a Director, or to vote in person at the meeting. The Board of Directors has enclosed a proxy card for stockholders of record to use to grant a voting proxy.

If your shares are held in a brokerage account or by another nominee, you are considered the beneficial owner of shares held in “street name,” and these proxy materials are being forwarded to you by your broker or nominee together with a voting instruction card. As the beneficial owner, you have the right to direct your broker or nominee how to vote. Since you are not the stockholder of record, however, you may not vote these shares in person at the meeting unless you obtain from the broker or nominee that holds your shares a valid proxy giving you the right to vote the shares. Your broker or nominee should have enclosed or provided voting instructions for you to use in directing the broker or nominee how to vote your shares. If you hold your shares through a broker and you do not give instructions to the record holder on how to vote, the record holder will be entitled to vote your shares in its discretion on certain matters considered routine, such as Proposals 2, 4 and 5. Proposals 1 and 3 are not considered a routine matter. If you hold your shares in street name and you do not instruct your broker how to vote for Proposals 1 or 3, no votes will be cast on your behalf for these non-routine matters for which you have not provided voting instructions. These “broker non-votes” will be treated as shares that are present and entitled to vote for purposes of determining the presence of a quorum, but not as shares entitled to vote on these non-routine proposals.

Q: May I attend the 2024 Annual Meeting of Stockholders?

A: You are entitled to attend the 2024 Annual Meeting of Stockholders only if you own Common Stock as of the close of business on the Record Date, September 27, 2024, or you hold a valid proxy for the 2024 Annual Meeting of Stockholders. You should be prepared to present photo identification for admittance. If you are not a record holder but hold shares beneficially through a broker or nominee (that is, in “street name”), you should provide proof of beneficial ownership on the Record Date, such as your most recent account statement, a copy of the voting instruction card provided by your broker or nominee, or other similar evidence of ownership. If you do not provide photo identification or comply with the other procedures outlined above upon request, you may not be admitted to the 2024 Annual Meeting of Stockholders. The 2024 Annual Meeting of Stockholders will begin promptly at 9:30 a.m. (Eastern Time). Check-in will begin at 9:00 a.m., and you should allow ample time for the check-in procedures.

Q: How can I vote my shares in person at the 2024 Annual Meeting of Stockholders?

A: You may vote by ballot in person at the 2024 Annual Meeting of Stockholders any shares that you hold as the stockholder of record. You may only vote in person shares held in street name if you obtain from the broker or nominee that holds your shares a valid proxy giving you the right to vote the shares.

Q: How can I vote my shares without attending the 2024 Annual Meeting of Stockholders?

A: Whether you hold shares directly as the stockholder of record or beneficially in street name, you may, without attending the meeting, direct how your shares are to be voted.

Stockholder of Record — Shares Registered in Your Name: If you are a stockholder of record, in addition to voting in person at the 2024 Annual Meeting of Stockholders, you may vote by submitting a proxy through the internet, or vote by proxy using a proxy card. Whether or not you plan to attend the 2024 Annual Meeting of Stockholders, we urge you to submit a proxy to ensure your vote is counted. You may still attend the meeting and vote in person even if you have already voted by proxy.

· Submit a proxy by Internet, by going to the web address www.voteproxy.com/tovx and following the instructions for internet voting shown on your proxy card. Your Internet vote must be received by 11:59 p.m., Eastern Time, on October 30, 2024 to be counted.

· Submit a proxy by mail, by completing, signing, dating and mailing the enclosed proxy card in the envelope provided. If you return your signed proxy card to us before the 2024 Annual Meeting of Stockholders, we will vote your shares as you direct.

Beneficial Owner — Shares Registered in the Name of a Broker or Bank: If you are a beneficial owner of shares registered in the name of your broker, bank, or other agent, you should have received an instruction card containing voting instructions from that organization rather than from us. You will be provided with instructions to vote by internet or to vote by mailing in your instruction card. Simply follow the voting instructions in the voting instruction card to ensure that your vote is counted.

We provide internet proxy voting to allow record holders to vote your shares online, with procedures designed to ensure authenticity and correctness of your proxy vote instructions. Please be aware, however, that you must bear any costs associated with your internet access, such as usage charges from internet access providers and telephone companies.

Q: Can I change or revoke my vote?

A: You may change or revoke your vote at any time prior to the final vote at the 2024 Annual Meeting of Stockholders. For shares held directly in your name, you may accomplish this by: (1) sending a written notice of revocation to our Corporate Secretary at Theriva Biologics, Inc., 9605 Medical Center Drive, Suite 270, Rockville, Maryland 20850; (2) submitting a new proxy bearing a later date (which automatically revokes the earlier proxy) subject to the voting deadlines that are described on the proxy card; (3) granting a subsequent proxy through the internet; subject to the voting deadlines that are described on the proxy card; or (4) by attending the 2024 Annual Meeting of Stockholders and voting in person. Attendance at the meeting will not cause your previously granted proxy to be revoked unless you specifically so request. Even if you plan to attend the 2024 Annual Meeting of Stockholders, we recommend that you also submit your or vote through the internet so that your vote will be counted if you later decide not to attend the 2024 Annual Meeting of Stockholders.

If your shares are held by your broker or bank as nominee or agent, you should follow the instructions provided by your broker or bank.

Q: Who can help answer my questions?

A: If you have any questions about the 2024 Annual Meeting of Stockholders or how to vote or revoke your proxy, or you need additional copies of this Proxy Statement or voting materials, you should contact our Corporate Secretary at Theriva Biologics, Inc., 9605 Medical Center Drive, Suite 270, Rockville, Maryland 20850 or by phone at (301) 417-4364.

Q: What is the voting requirement to approve each of the proposals?

Proposal	Vote Required	Voting Options	Impact of “Abstain” Vote	Impact of Broker Non- Votes
Proposal 1: Election of Directors	Plurality – the four (4) director nominees who receive the most “FOR” votes will be elected to serve on the Board	“FOR” “WITHELD”	No effect	No effect

Proposal 2: Ratification of Appointment of Independent Registered Public Accounting Firm	The affirmative vote of a majority of the shares present in person or by proxy and entitled to vote on the matter is required.	“FOR” “AGAINST” “ABSTAIN”	Counts as a vote “AGAINST” this proposal.	Not applicable

Proposal 3: Stock Incentive Plan Amendment Proposal	The affirmative vote of a majority of the shares present in person or by proxy and entitled to vote on the matter is required.	“FOR” “AGAINST” “ABSTAIN”	Counts as a vote “AGAINST” this proposal.	No effect

Proposal 4: Authorized Common Stock Increase Proposal	The affirmative vote of a majority of the Company’s outstanding shares of Common Stock is required.	“FOR” “AGAINST” “ABSTAIN”	Counts as a vote “AGAINST” this proposal.	Not applicable

Proposal 5: Adjournment Proposal	The affirmative vote of a majority of the shares present in person or by proxy and entitled to vote on the matter is required.	“FOR” “AGAINST” “ABSTAIN”	Counts as a vote “AGAINST” this proposal.	Not applicable

Your shares will be voted in accordance with your instructions. If you are a stockholder of record and sign, date and return a proxy card but do not indicate how you wish to vote your shares, the appointed proxies named on the proxy card will vote your shares “for” each of the nominees with respect to Proposal 1, “for” Proposals 2, 3, 4 and 5, and in the discretion of the appointed proxy named on the proxy card with respect to any other business properly brought before the 2024 Annual Meeting of Stockholders..

Q: What is a quorum and why is it necessary?

A: Conducting business at the 2024 Annual Meeting of Stockholders requires a quorum. The presence, either in person or by proxy, of the holders of shares of stock having one-third of the voting power of the shares of stock entitled to vote on September 27, 2024 are necessary to constitute a quorum to conduct business at the 2024 Annual Meeting of Stockholders. Your shares will be counted towards the quorum only if you submit a valid proxy (or, in the case of a beneficial owner, one is submitted on your behalf by your broker, bank or other nominee) or if you vote in person at the 2024 Annual Meeting of Stockholders. Abstentions and broker non-votes (which result when your shares are held in “street name,” your broker does not have discretion to vote such shares and you do not tell the nominee how to vote your shares, as described in detail below) are treated as present for purposes of determining whether a quorum exists. Broker non-votes are relevant in determining whether a quorum is present at the meeting. If there is no quorum, the holders of a majority of shares present at the meeting in person or represented by proxy may adjourn the meeting to another date.

Q: What are broker non-votes?

A: Under the rules of the New York Stock Exchange, member brokers who hold shares in street name for their customers that are the beneficial owners of those shares have the authority to only vote on certain “routine” items in the event that they have not received instructions from beneficial owners. Under New York Stock Exchange rules, when a proposal is not a “routine” matter and a member broker, bank or nominee has not received voting instructions from the beneficial owner of the shares with respect to that proposal, the brokerage firm, bank or nominee may not vote the shares on that proposal since it does not have discretionary authority to vote those shares on that matter. A “broker non-vote” is submitted when a broker, bank or nominee returns a proxy card and indicates that, with respect to particular matters, it is not voting a specified number of shares on that matter, as it has not received voting instructions with respect to those shares from the beneficial owner and does not have discretionary authority to vote those shares on such matters. If you hold your shares in street name and you do not instruct your broker how to vote on these matters not considered routine, no votes will be cast on your behalf with respect to these non-routine matters. “Broker non-votes” are not entitled to vote at the 2024 Annual Meeting of Stockholders with respect to the matters to which they apply; however, “broker non-votes” will be included for purposes of determining whether a quorum is present at the 2024 Annual Meeting of Stockholders.

Proposals 1 and 3 are each considered a “non-routine” matter. As a result, brokers, banks or nominees that do not receive instructions with respect to Proposal 1 or 3 from their customers will not be entitled to vote on such proposal for which instructions were not received.

Proposals 2, 4 and 5 are considered “routine” matters. As a result, brokers that do not receive instructions with respect to Proposals 2, 4 and 5 from their customers will be entitled to vote on such proposals in their discretion.

Q: What should I do if I receive more than one set of voting materials?

A: You may receive more than one set of voting materials, including multiple copies of this Proxy Statement and multiple proxy cards or voting instruction cards. For example, if you hold your shares in more than one brokerage account, you will receive a separate voting instruction card for each brokerage account in which you hold shares. If you are a stockholder of record and your shares are registered in more than one name, you will receive more than one proxy card. Please complete, sign, date, and return each proxy card and voting instruction card that you receive.

Q: Where can I find the voting results of the 2024 Annual Meeting of Stockholders?

A: We intend to announce the voting results at the 2024 Annual Meeting of Stockholders and publish final results in a Current Report on Form 8-K that will be filed with the U.S. Securities and Exchange Commission (the “SEC”) within four (4) business days after the meeting. If final voting results are not available to us in time to file a Current Report on Form 8-K within four (4) business days after the meeting, we intend to file a Current Report on Form 8-K to publish preliminary results and, within four (4) business days after the final results are known to us, file an additional Current Report on Form 8-K to publish the final results.

Q: What happens if additional matters are presented at the 2024 Annual Meeting of Stockholders?

A: Other than the five (5) items of business described in this Proxy Statement, we are not aware of any other business to be acted upon at the 2024 Annual Meeting of Stockholders. If you grant a proxy, the person named as proxy holder, Mr. Steven Shallcross, our Chief Executive Officer, Chief Financial Officer and Director, will have the discretion to vote your shares on any additional matters properly presented for a vote at the meeting. If for any unforeseen reason any of our nominees are not available as a candidate for director, the person named as proxy holder will vote your proxy for any one or more other candidates nominated by the Board of Directors.

Q: Who will count the votes?

A: One or more inspectors of election will tabulate the votes.

Q: Is my vote confidential?

A: Proxy instructions, ballots, and voting tabulations that identify individual stockholders are handled in a manner that protects your voting privacy. Your vote will not be disclosed, either within our business or to anyone else, except: (1) as necessary to meet applicable legal requirements; (2) to allow for the tabulation of votes and certification of the vote; or (3) to facilitate a successful proxy solicitation.

Q: Who will bear the cost of soliciting votes for the 2024 Annual Meeting of Stockholders?

A: The Board of Directors is making this solicitation on our behalf, and we will pay the entire cost of preparing, assembling, printing, mailing, and distributing these proxy materials. Certain of our directors, officers, and employees, without any additional compensation, may also solicit your vote in person, by telephone, or by electronic communication. On request, we will reimburse brokerage houses and other custodians, nominees, and fiduciaries for their reasonable out-of-pocket expenses for forwarding proxy and solicitation materials to stockholders. In addition to the use of the mail, proxies may be solicited by personal interview, telephone, telegram, facsimile and advertisement in periodicals and postings, in each case by our directors, officers and employees without additional compensation.

Q: When are stockholder proposals and director nominations due for next year’s (2025) Annual Meeting of Stockholders?

INFORMATION REGARDING THE BOARD OF DIRECTORS AND CORPORATE GOVERNANCE

Independence of the Board of Directors

Our Common Stock is listed on the NYSE American. Under the NYSE American listing standards, independent directors must comprise a majority of a listed company’s board of directors and all members of the Audit Committee, Compensation Committee and Nominations Committee must be independent. Audit Committee members must also satisfy the independence criteria set forth in Rule 10A-3 under the Exchange Act and Compensation Committee members must also satisfy the independence criteria set forth in Rule 10C-1 under the Exchange Act. Under the NYSE American listing standards, a director will only qualify as an “independent director” if, in the opinion of that company’s Board of Directors, that person does not have a relationship that would interfere with the exercise of independent judgment in carrying out the responsibilities of a director.

In order to be considered to be independent for purposes of Rule 10A-3, a member of an Audit Committee of a listed company may not, other than in his or her capacity as a member of the Audit Committee, the board of directors, or any other board committee: (i) accept, directly or indirectly, any consulting, advisory or other compensatory fee from the listed company or any of its subsidiaries, or (ii) be an affiliated person of the listed company or any of its subsidiaries.

The Board of Directors undertook a review of the independence of the members of the Board of Directors and considered whether any director has a material relationship with our company that could compromise his or her ability to exercise independent judgment in carrying out his or her responsibilities. Based upon information requested from and provided by each director concerning their background, employment and affiliations, including family relationships, the Board of Directors has determined that all of our current directors, except Mr. Shallcross, due to his current position as Chief Executive Officer and Chief Financial Officer of our company, is “independent” as that term is defined under the rules of the NYSE American. As a result, Mr. Kraws, Dr. Monahan and Mr. Wolf are deemed to be “independent” as that term is defined under the rules of the NYSE American.

In making these determinations, the Board of Directors considered the current and prior relationships that each non-employee director has with our company and all other facts and circumstances the Board of Directors deemed relevant in determining their independence, including the beneficial ownership of capital stock by each non-employee director, and the transactions involving them described in the section of this proxy statement entitled “Certain Relationships and Related Party Transactions.”

Board Leadership Structure

The Board of Directors has an independent Chairman, Mr. Kraws, who has authority, among other things, to call and preside over meetings of the Board of Directors, including meetings of the independent directors, to set meeting agendas and to determine materials to be distributed to the Board of Directors. Accordingly, the Chairman of the Board has substantial ability to shape the work of the Board of Directors. We believe that separation of the positions of Chairman of the Board and Chief Executive Officer reinforces the independence of the Board of Directors in its oversight of our business and affairs. In addition, we believe that having an independent Chairman of the Board creates an environment that is more conducive to objective evaluation and oversight of management’s performance, increasing management accountability and improving the ability of the Board of Directors to monitor whether management’s actions are in our best interests and the best interests of our stockholders. As a result, we believe that having an independent Chairman of the Board can enhance the effectiveness of the Board of Directors as a whole.

Risk Oversight

One of the Board of Directors’ key functions is informed oversight of our risk management process. The Board of Directors does not have a standing risk management committee, but rather administers this oversight function directly through the Board of Directors as a whole, as well as through various standing committees of the Board of Directors that address risks inherent in their respective areas of oversight. In particular, the Board of Directors is responsible for monitoring and assessing strategic risk exposure, including a determination of the nature and level of risk appropriate for us. Our Audit Committee has the responsibility to consider and discuss our major financial risk exposures and the steps our management has taken to monitor and control these exposures, including guidelines and policies to govern the process by which risk assessment and management is undertaken. The Audit Committee also monitors compliance with legal and regulatory requirements, in addition to oversight of the performance of our internal audit function at the time of its establishment. Our Nominations Committee monitors the effectiveness of our corporate governance guidelines, including whether they are successful in preventing illegal or improper liability-creating conduct. Our Compensation Committee assesses and monitors whether any of our compensation policies and programs has the potential to encourage excessive risk-taking.

Board and Committee Meetings and Attendance

During the year ended December 31, 2023, the Board of Directors held six (6) meetings. During the year ended December 31, 2023, our Audit, Compensation and Nominations Committees met seven (7) times, two (2) times, and one (1) time, respectively. Each director attended at least seventy five percent (75%) of the aggregate of all meetings of the Board of Directors and all of the Committee meetings, for the Committees on which he serves.

Board Attendance at Annual Stockholders’ Meeting

Our policy is to invite and encourage each member of the Board of Directors to be present at our annual meetings of stockholders (assuming that we hold in-person annual meetings). Only one director, Steven Shallcross, attended our 2023 Annual Meeting of Stockholders in person and our other three directors attended our 2023 Annual Meeting of Stockholders via telephone.

Review of Transactions with Related Persons

Pursuant to our charter, our Audit Committee reviews on an on-going basis for potential conflicts of interest, and approves if appropriate, all our “Related Party Transactions.” For purposes of the Audit Committee Charter, “Related Party Transactions” means those transactions required to be disclosed pursuant to Item 404 of SEC Regulation S-K.

A discussion of our current related person transactions appears in this Proxy Statement under “Certain Relationships and Related Party Transactions.”

Communication with Directors

Stockholders may direct any communications intended for the Board of Directors to our Corporate Secretary by telephone at (301) 417-4364, by facsimile at (301) 417-4367, or by mail to Theriva Biologics, Inc., 9605 Medical Center Drive, Suite 270, Rockville, Maryland 20850.

This centralized process assists the Board of Directors in reviewing and responding to stockholder communications in an appropriate manner. If a stockholder wishes to direct any communication to a specific member of the Board of Directors, the name of that member of the Board of Directors should be noted in the communication. The Board of Directors has instructed the Corporate Secretary to forward stockholder correspondence only to the intended recipients, and has also instructed the Corporate Secretary to review all stockholder correspondence and, in the Corporate Secretary’s discretion, refrain from forwarding any items deemed to be of a commercial or frivolous nature or otherwise inappropriate for the Board of Directors’ consideration. Any such items may be forwarded elsewhere in the Company for review and possible response.

Code of Conduct

We have adopted a code of conduct that applies to all officers, directors and employees. The Code of Conduct is intended to promote honest and ethical conduct, full, accurate and timely disclosure, and compliance with all applicable laws and government regulations. The full text of the code of conduct is posted on our website at www.therivabio.com and a copy will be made available to stockholders without charge, upon request, in writing to the Corporate Secretary at 9605 Medical Center, Suite 270, Rockville, Maryland 20850. If we make any substantive amendments to the code of conduct or grant any waiver from a provision of the code of conduct to any executive officer or director, we will promptly disclose the nature of the amendment or waiver on our website or by filing with the SEC a Current Report on Form 8-K, in each case if such disclosure is required by SEC or the NYSE American rules.

Code of Ethics for Financial Management

We adopted a Code of Ethics for Financial Management that applies to all persons responsible for our financial management. The Code of Ethics for Financial Management is intended to promote professional conduct in our financial management. A copy of our Code of Ethics for Financial Management is available on our website at www.therivabio.com and a copy will be made available to stockholders without charge, upon request, in writing to the Corporate Secretary at 9605 Medical Center, Suite 270, Rockville, Maryland 20850. Violations of the Code of Ethics for Financial Management may result in disciplinary action. If we make any substantive amendments to the Code of Ethics for Financial Management or grant any waiver from a provision of the Code of Ethics for Financial Management to any director or officer, we will promptly disclose the nature of the amendment or waiver on our website.

Anti-Hedging/Anti-Pledging Policy

The Company has adopted an insider trading policy which incorporates anti-hedging and anti-pledging provisions. Consequently, no employee, executive officer or director may enter into a hedge or pledge of the Company’s Common Stock, including short sales, derivatives, put options, swaps and collars.

INFORMATION REGARDING COMMITTEES OF THE BOARD OF DIRECTORS

The Board of Directors has the authority to appoint committees to perform certain management and administration functions. As disclosed above, the Board of Directors has established an Audit Committee, a Compensation Committee and a Nominations Committee. The Board of Directors may establish other committees to facilitate the management of our company’s business. The composition and functions of each committee are described below. Members serve on these committees until their resignation or until otherwise determined by the Board of Directors.

All of the committees comply with all applicable requirements of the Sarbanes-Oxley Act of 2002, NYSE American, and SEC, rules and regulations as further described below. The charters for each of these committees are available on our website at www.therivabio.com.

· reviewing and approving the internal corporate audit staff functions;

· approving the retention or replacement of the independent auditors;

· oversee cybersecurity risk management strategy and infrastructure; and

· reviewing and discussing our annual audited financial statements and quarterly financial statements with management and the independent auditor.

The Audit Committee operates pursuant to a written charter adopted by the Board of Directors, which is available on our website at www.therivabio.com. The charter describes in more detail the nature and scope of responsibilities of the Audit Committee.

Compensation Committee

Mr. Kraws (Chairman), Dr. Monahan and Mr. Wolf currently serve as members of the Compensation Committee, each of whom the Board of Directors has determined is independent in accordance Rule 10C-1 under the Exchange Act and the NYSE American definition of independence and that each is a “non-employee director” as defined in Rule 16b-3 promulgated under the Exchange Act.

The primary purpose of the Compensation Committee is to assist the Board of Directors in fulfilling its oversight responsibilities relating to compensation of our Chief Executive Officer and other senior executive officers, including evaluating and approving officer’s benefits, bonus, incentive compensation, severance, equity based-compensation and other compensation.

The Compensation Committee operates pursuant to a written charter adopted by the Board of Directors, which is available on our website at www.therivabio.com. The charter describes in more detail the nature and scope of responsibilities of the Compensation Committee.

Nominations Committee

Dr. Monahan (Chairman), Mr. Kraws, and Mr. Wolf currently serve as members of the Nominations Committee, each of whom the Board of Directors has determined is independent in accordance with the NYSE American definition of independence. Specific responsibilities of the Nominations Committee include:

· considering and recommending to the Board of Directors, candidates for appointment or election as directors, and making recommendations regarding re-election of incumbent directors;

· considering and recommending to the Board of Directors changes to the size of the Board of Directors or any Committee; and

· recommending to the Board of Directors, candidates to vacancies on any committees of the Board of Directors.

The Nominations Committee believes that candidates for director should have certain minimum qualifications, including the ability to read and understand basic financial statements, being over 21 years of age and having the highest personal integrity and ethics. The Nominations Committee also intends to consider such factors as possessing relevant expertise upon which to be able to offer advice and guidance to management, having sufficient time to devote to our affairs, demonstrated excellence in his or her field, having the ability to exercise sound business judgment and having the commitment to rigorously represent the long-term interests of our stockholders. However, the Nominations Committee retains the right to modify these qualifications from time to time. The Nominations Committee does not have a set policy or process for considering diversity in identifying nominees, but endeavors to establish a diversity of background and experience in a number of areas of core competency, including business judgment, management, accounting, finance, knowledge of our industry, strategic vision, research and development and other areas relevant to our business. Candidates for director nominees are reviewed in the context of the current composition of the Board of Directors, our operating requirements and the long-term interests of its stockholders. In conducting this assessment, the Nominations Committee typically considers diversity, age, skills and such other factors as it deems appropriate, given the current needs of the Company and the Board of Directors, to maintain a balance of knowledge, experience and capability.

In the case of incumbent directors whose terms of office are set to expire, the Nominations Committee reviews these directors’ overall service to us during their terms, including the number of meetings attended, level of participation, quality of performance and any other relationships and transactions that might impair the directors’ independence. The Nominations Committee also takes into account the results of the Board of Directors’ self-evaluation, conducted annually on a group and individual basis. In the case of new director candidates, the Nominations Committee also determines whether the nominee is independent for NYSE American purposes, which determination is based upon applicable NYSE American listing standards, applicable SEC rules and regulations and the advice of counsel, if necessary. The Nominations Committee then uses its network of contacts to compile a list of potential candidates, but may also engage, if it deems appropriate, a professional search firm. The Nominations Committee conducts any appropriate and necessary inquiries into the backgrounds and qualifications of possible candidates after considering the function and needs of the Board of Directors. The Nominations Committee meets to discuss and consider the candidates’ qualifications and then selects a nominee for recommendation to the Board of Directors by majority vote.

The Nominations Committee operates pursuant to a written charter adopted by the Board of Directors, which is available on our website at www.therivabio.com. The charter describes in more detail the nature and scope of responsibilities of the Nominations Committee.

The Nominations Committee will consider director candidates recommended by stockholders. The Nominations Committee does not intend to alter the manner in which it evaluates candidates, including the minimum criteria set forth above, based on whether or not the candidate was recommended by a stockholder. Under our current governing documents, stockholders wishing to directly recommend candidates for election to the Board of Directors at our next annual meeting to be included in our Proxy Statement must do so by giving written notice to: Chairman of the Nominations Committee, Theriva Biologics, Inc., 9605 Medical Center Drive, Suite 270, Rockville, Maryland 20850. Any such notice must be delivered to the Chairman not less than 120 days prior to the anniversary of the preceding year’s annual meeting. The notice must state: (1) the name and address of the stockholder making the recommendations; (2) the name, age, business address, and residential address of each person recommended; (3) the principal occupation or employment of each person recommended; (4) the class and number of shares of the Company’s stock that are beneficially owned by each person recommended and by the recommending stockholder; (5) any other information concerning the persons recommended that must be disclosed in nominee and proxy solicitations in accordance with Regulation 14A of the Exchange Act; and (6) a signed consent of each person recommended stating that he or she consents to serve as a director of the Company if elected.

During 2023, our independent, non-executive Chairman of the Board of Directors received an annual cash retainer of $150,000, each other non-employee member of the Board of Directors received an annual cash retainer of $43,000, all non-employee directors receive an annual cash fee of $7,500, $5,000 and $3,750 for service as a member of the Audit, Compensation and Nominations Committees, respectively, or an additional annual cash fee of $15,000, $10,000 and $7,500 for service as Chairman of the Audit, Compensation and Nominations Committees, respectively. In addition, each non-employee member of the Board of Directors was issued an option exercisable for 4,400 shares of our Common Stock, for a term of seven years, vesting monthly over one year of the date of grant. In setting 2023 compensation for directors, the Compensation Committee relied on a report from Meridian Compensation Partners, LLC.

LIMITS ON LIABILITY AND INDEMNIFICATION

Our Articles of Incorporation and Second A&R Bylaws provide that we will indemnify and hold harmless each person who serves at any time as a director or officer from and against any and all claims, judgments and liabilities to which such person shall become subject by reason of the fact that he or she is or was a director or officer of the Company, and shall reimburse such person for all legal and other expenses reasonably incurred by him or her in connection with any such claim or liability. We believe that this indemnification covers at least negligence and gross negligence on the part of the indemnified parties. Insofar as indemnification for liabilities under the Securities Act of 1933, as amended (the “Securities Act”) may be permitted to directors, officers, and controlling persons of the Company under the foregoing provisions or otherwise, we have been advised that in the opinion of the SEC that indemnification is against public policy as expressed in the Securities Act, and is therefore unenforceable. We entered into an indemnification agreement with our directors and officers. The agreement confirms our obligation to indemnify the directors and officers to the fullest extent authorized by our Articles of Incorporation and Second A&R Bylaws and supplements the indemnification otherwise available to the covered person under our Articles of Incorporation and Second A&R Bylaws. The form of indemnification agreement was described and filed as an exhibit to the Form 8-K we filed with the SEC on January 6, 2009.

COMPENSATION COMMITTEE INTERLOCKS

During the last fiscal year ended December 31, 2023, none of our executive officers served on the Board of Directors or Compensation Committee of any other entity whose officers served either on our Board of Directors or Compensation Committee.

PROPOSAL 2

RATIFICATION OF APPOINTMENT OF

INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

The Audit Committee has selected BDO USA, P.C., an independent registered accounting firm, to audit the books and financial records of the Company for the year ending December 31, 2024. Theriva is asking its stockholders to ratify the appointment of BDO USA, P.C. as Theriva’s independent registered public accounting firm for fiscal 2023.

A representative of BDO USA, P.C. is expected to be present either in person or via teleconference at the 2024 Annual Meeting of Stockholders and available to respond to appropriate questions, and will have the opportunity to make a statement if he or she desires to do so.

Vote Required

The affirmative vote of the holders of a majority of the shares present in person or represented by proxy and entitled to vote on this matter at the 2024 Annual Meeting of Stockholders will be required to approve the ratification of the appointment of Theriva’s independent registered public accounting firm. Abstentions will be counted and will have the same effect as a vote against the proposal. Ratification of the appointment of BDO USA, P.C. by our stockholders is not required by law, our Second A&R Bylaws or other governing documents. As a matter of policy, however, the appointment is being submitted to our stockholders for ratification at the 2024 Annual Meeting of Stockholders. If our stockholders fail to ratify the appointment, the Audit Committee will reconsider whether or not to retain that firm. Even if the appointment is ratified, the Audit Committee, in its discretion, may direct the appointment of different independent auditors at any time during the year if they determine that such a change would be in our best interest and the best interests of our stockholders.

THE BOARD OF DIRECTORS UNANIMOUSLY RECOMMENDS THAT YOU VOTE “FOR” RATIFICATION OF THE SELECTION OF BDO USA, P.C. AS OUR INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM FOR OUR FISCAL YEAR ENDING ON DECEMBER 31, 2024.

REPORT OF THE AUDIT COMMITTEE OF THE BOARD OF DIRECTORS

The Audit Committee reviews our financial reporting process on behalf of the Board of Directors. In January 2007, the Board of Directors adopted a written charter for the Audit Committee, which it re-evaluates annually. In fulfilling its responsibilities, the Audit Committee has reviewed and discussed the audited financial statements contained in the Annual Report on Form 10-K for the year ended December 31, 2023 (the “2023 Annual Report on Form 10-K”) with our management and our independent registered public accounting firm for such year, BDO USA, P.C. Our management is responsible for the financial statements and the reporting process, including the system of internal controls. The independent registered public accounting firm is responsible for expressing an opinion on the conformity of those audited financial statements with accounting principles generally accepted in the United States.

The Audit Committee (1) discussed with BDO USA, P.C. the matters required by the applicable requirements of the Public Company Accounting Oversight Board (“PCAOB”) and the SEC; (2) received the written disclosures and the letter from BDO USA, P.C. required by the applicable requirements of the PCAOB regarding the independent accountant’s communications with the audit committee concerning independence; and (3) discussed with BDO USA, P.C. its independence. The Audit Committee also considered whether, and determined that, the independent registered public accounting firm’s provision of other non-audit services to us was compatible with maintaining BDO USA, P.C.’s independence.

During 2023, management evaluated our system of internal control over financial reporting in accordance with the requirements set forth in Section 404 of the Sarbanes-Oxley Act of 2002 and related regulations. The Audit Committee was kept apprised of the progress of the evaluation and provided oversight and advice to management during the process. In connection with this oversight, the Audit Committee received periodic updates provided by management and the independent registered public accounting firm at each regularly scheduled Audit Committee meeting. At the conclusion of the process, management provided the Audit Committee with a report on the effectiveness of our internal control over financial reporting. The Audit Committee also reviewed the report of management contained in our 2023 Annual Report on Form 10-K, as well as the Report of Independent Registered Public Accounting Firm and the Consolidated Financial Statements (included in the 2023 Annual Report on Form 10-K). These reports related to its audit of the consolidated financial statements. The Audit Committee continues to oversee our efforts related to our internal control over financial reporting and management’s preparations for the evaluations in 2024.

It should be noted that the members of our Audit Committee are not our employees and are not performing the functions of auditors or accountants. Accordingly, it is not the duty or responsibility of the Audit Committee or its members to conduct “field work” or other types of auditing or accounting reviews or procedures or to set auditor independence standards. Members of the Audit Committee necessarily rely on the information provided to them by management and the independent auditors. Accordingly, the Audit Committee’s considerations and discussions referred to above do not constitute assurance that the audit of our financial statements has been carried out in accordance with generally accepted auditing standards or that our auditors are in fact independent.

Based on the review and discussions referred to above, the Audit Committee recommended to the Board of Directors (and the Board of Directors approved) that the audited financial statements be included in our Annual Report on Form 10-K for the year ended December 31, 2023, for filing with the SEC.

Members of the Audit Committee:

Jeffrey Wolf (Chairman)
Jeffrey J. Kraws
John Monahan

The material in this report is not “soliciting material,” is not deemed “filed” with the SEC and is not incorporated by reference in any filing of the Company under the Securities Act of 1933, as amended, or the Exchange Act, whether made before or after the date hereof and irrespective of any general incorporation language in any such filing.

Audit Committee Pre-Approval Policy

The Audit Committee has adopted procedures for pre-approving all audit and non-audit services provided by the independent registered public accounting firm, including the fees and terms of such services. These procedures include reviewing detailed back-up documentation for audit and permitted non-audit services. The documentation includes a description of, and a budgeted amount for, particular categories of non-audit services that are recurring in nature and therefore anticipated at the time that the budget is submitted. Audit Committee approval is required to exceed the pre-approved amount for a particular category of non-audit services and to engage the independent registered public accounting firm for any non-audit services not included in those pre-approved amounts. For both types of pre-approval, the Audit Committee considers whether such services are consistent with the rules on auditor independence promulgated by the SEC and the PCAOB. The Audit Committee may form and delegate pre-approval authority to subcommittees consisting of one or more members of the Audit Committee, and such subcommittees must report any pre-approval decisions to the Audit Committee at its next scheduled meeting. All of the services provided by the independent registered public accounting firm were pre-approved by the Audit Committee.

Narrative Disclosure to Summary Compensation Table

Overview of Our Compensation Program

A. Philosophy and Objectives

The Compensation Committee seeks to attract and retain superior executive talent by offering competitive base salaries, bonuses and long-term incentives. The Compensation Committee’s philosophy is to deliver higher rewards for superior performance and consequences for underperformance. It is also the Compensation Committee’s practice to provide a balanced mix of cash and equity-based compensation that aligns both the short and long-term interests of our executives with that of our stockholders. Our executive compensation program is based on the following philosophies and objectives:

●

Compensation Should Align with Stockholders’ Interests — The Compensation Committee believes that executives’ interests should be aligned with those of stockholders. Executives are granted stock options so that their total compensation is tied directly to value realized by our stockholders. Executive bonuses are tied directly to the achievement of performance goals that the Compensation Committee believes will ultimately drive stockholder value creation.

●

Compensation is Competitive — The Compensation Committee seeks to provide a total compensation package that attracts, motivates and retains the executive talent that we need in order to maximize our return to stockholders. To accomplish this objective, executive compensation is reviewed annually to ensure that compensation levels are competitive and reasonable relative to our level of performance and to the compensation opportunities provided by comparable companies with which we compete for talent.

●

Compensation Motivates and Rewards the Achievement of Goals — Our executive compensation program is designed to appropriately reward both individual and collective performance that meets and exceeds our annual, long-term and strategic goals. To accomplish this objective, a substantial percentage of total compensation is variable and “at risk”, both through annual incentive compensation in the form of cash bonuses and the granting of long-term incentive awards.

B. Oversight of Executive Compensation

Role of the Compensation Committee

Pursuant to the terms of its charter, the Compensation Committee is responsible for the review of all aspects of our executive compensation program and makes decisions regarding the compensation of our Named Executive Officers. Our Named Executive Officers for the year ended December 31, 2023 were Steven Shallcross, our Chief Executive Officer who also serves as our Chief Financial Officer, and Frank Tufaro, who served as our Chief Operating Officer until his separation on May 10, 2023.

The Compensation Committee’s responsibilities include but are not limited to the following:

	●	Establishing on an annual basis the performance goals and objectives for purposes of determining the compensation of our Chief Executive Officer and other senior executive officers.
	●	Evaluating the Chief Executive Officer’s and other senior executive officers’ performance at least annually in light of those goals and objectives, and based upon these evaluations setting the compensation level for those officers.
	●	Reviewing the competitive position of, and making recommendations to, the Board of Directors with respect to the cash-based and equity-based compensation plans and our programs relating to compensation and benefits.
	●	Overseeing administration of our stock option plan and incentive compensation plans, making recommendations to the Board of Directors regarding the granting of options and incentives and otherwise assisting the Board of Directors in administering awards under these plans.
	●	Reviewing the financial performance and operations of our major benefit plans.

Additional information regarding the Compensation Committee’s responsibilities is set forth in its charter, which is posted on our website at www.therivabio.com.

Role of the Chief Executive Officer

Our Chief Executive Officer makes recommendations to the Compensation Committee regarding the compensation of our other Named Executive Officers. The Chief Executive Officer does not participate in any discussions or processes concerning his own compensation and participates in a non-voting capacity in discussions or processes concerning the compensation of our other members of management. In addition to our Chief Executive Officer, other members of our management and consultants also attend Compensation Committee meetings from time to time and may take part in discussions of executive compensation.

C. Program Design

The Compensation Committee uses a simple and straightforward approach in compensating our Named Executive Officers in which base salary, annual incentives and stock options are the principal components. In addition, executive officers generally participate in the same benefit programs as other full-time employees.

Our executive compensation program is designed to provide executives with a reasonable level of fixed compensation through base salary and benefits, and an opportunity to earn incentive compensation through the annual and long-term incentive programs based on a mix of individual and corporate performance, individual performance and the value of our stock. We do not currently have formal policies for allocating compensation among base salary, performance-based bonus and equity awards. Instead our Compensation Committee uses its judgment to establish a total direct compensation opportunity for each Named Executive Officer that is a mix of current, short-term and long-term incentive compensation and cash and non-cash compensation that it believes appropriate to achieve the goals of our executive compensation program and corporate objectives. Our target pay mix places a significant emphasis on performance based variable compensation. The incentive plans are designed to pay well when performance meets or exceeds expectations and pay little or no incentive if performance is below expectations.

In designing and implementing our executive compensation program, our Compensation Committee considers our company’s operating and financial objectives, including our risk profile, and the effect that its executive compensation decisions will have on encouraging our executive officers to take an appropriate level of business risk consistent with our overall goal of enhancing long-term stockholder value. In particular, the Compensation Committee considers how our executive compensation program serves to achieve our operating and financial objectives while at the same time mitigating any incentives for our executive officers to engage in excessive risk-taking to achieve short-term results that may not be sustainable in the long-term.

Target compensation comprises base salary and performance based variable compensation, including targeted cash bonus amounts and equity-based compensation. As an executive’s level of responsibility increases, the Compensation Committee generally targets a greater portion of the executive’s compensation to be contingent upon performance in the form of variable compensation. For example, historically our Named Executive Officers have a higher percentage of compensation at risk (and thus greater upside and downside potential) relative to our other employees. The Compensation Committee believes this is appropriate because our Named Executive Officers have the greatest influence on our performance.

During 2023, the salary for our Chief Executive Officer who also serves as our Chief Financial Officer was 51% of his target compensation package and performance based variable compensation comprised 49% of his target compensation. Of the performance based variable compensation 52% was equity-based compensation and 49% was his target cash bonus. During 2023, our Chief Operating Officer Officer’s salary was 71% of his target annual compensation package and performance based variable compensation comprised 29% of his target annual compensation. Because he served only until May 10, 2023, our Chief Operating Officer received only a pro-rated amount of his base salary, was not paid a cash bonus and did not receive equity-based compensation in 2023.

D. Compensation Review Process

The Compensation Committee annually reviews compensation for our Named Executive Officers. The Compensation Committee considers the executive’s role and responsibilities, corporate and individual performance, and industry-wide compensation practices and trends for other companies of similar size. This approach is used to set base salaries, bonuses, stock option award levels and the mix of compensation elements.

We strive to attract and retain the most highly qualified executive officers in an extremely competitive market. Our Compensation Committee believes that it is important when making its compensation decisions to be informed as to the competitive market for executive talent, including the current practices of comparable public companies with which we compete for such talent. Consequently, our Compensation Committee reviewed an executive compensation benchmarking report prepared by Meridian Compensation Partners, LLC (“Meridian”) at the Compensation Committee’s request. With respect to its analysis of the compensation of the Chief Executive Officer, the Compensation Committee took into account that our Chief Executive Officer also serves as our Chief Financial Officer, which is not typical for most companies.

While the Compensation Committee does take into consideration the data it reviewed, the Committee does not attempt to benchmark our executive compensation against any specific level, range, or percentile of compensation paid at any other companies, does not apply any specific measures of internal or external pay equity in reaching its conclusions, and does not employ tally sheets, wealth accumulation, or similar tools in its analysis. Rather, the Compensation Committee reviews compensation data from the report mentioned above as reference points in making executive compensation decisions especially in light of the fact that our Chief Executive Officer is also performing the role of Chief Financial Officer. The Compensation Committee’s general aim is for our compensation to remain competitive with the market, falling above or below the median of the market data as appropriate based on corporate and individual executive performance, and other factors deemed to be appropriate. Competitive market positioning is only one of several factors, as described below, that the Compensation Committee considers in making compensation decisions, and therefore individual Named Executive Officer compensation may fall at varying levels as compared to the market data.

Our Compensation Committee values the opinion of our stockholders. At our 2022 Annual Meeting of Stockholders approximately 97% of the shares voted (excluding broker non-votes) were cast in support of our fiscal 2022 executive compensation and related disclosures. At that time, our Compensation Committee viewed those voting results as broad stockholder support for our executive compensation program and consequently made no material changes to the program or to our compensation policies. Our Compensation Committee will continue to consider input from stockholders, including through advisory votes on executive compensation, in making compensation decisions and reviewing executive compensation programs and policies.

We currently hold our advisory vote to approve the compensation of our named executive officers (“Say-on-Pay vote”) every three years. Stockholders have an opportunity to cast an advisory vote on the frequency of the Say-on-Pay vote at least every six years, and the next advisory vote on the frequency of the Say-on-Pay vote will be at our 2025 Annual Meeting of Stockholders.

E. Components of Compensation

We provide four compensation components to Named Executive Officers:

●

base salary;

●

bonuses based on the achievement of specified goals and objectives;

	●	long-term incentives; and

	●	benefits

1. Base Salaries

We provide our Named Executive Officers a base salary commensurate with their position, responsibilities and experience. In setting the base salary, the Compensation Committee considers the scope and accountability associated with each Named Executive Officer’s position and such factors as performance and experience of each Named Executive Officer. We design base pay to provide the essential reward for an employee’s work that is required to be competitive in attracting talent. Once base pay levels are initially determined, increases in base pay may be provided to recognize an employee’s specific performance achievements or expansion of responsibilities. The base salaries are targeted to be competitive with other similar biotechnology companies. Base salaries for the Named Executive Officers are set by their respective employment contracts and are reviewed annually by the Compensation Committee referencing an executive compensation benchmarking report provided by Meridian. Mr. Shallcross’ base salary was $585,000 for the year ended December 31, 2022. Mr. Shallcross received a 5% merit increase to $614,250 for the year ended December 31, 2023, and on December 14, 2023 received a 5% merit increase to $644,963.

executive compensation benchmarking report executive compensation benchmarking report Our former Chief Operating Officer, Dr. Tufaro, received a base salary of $375,000 for the year ended December 31, 2022. Dr. Tufaro received a 5% merit increase to $393,750 for the year ended December 31, 2023.

The below shows the 2023 annualized base salary levels for our Named Executive Officers, including a comparison with 2022.

	2022		2023
Named Executive Officer	Base Salary		Base Salary
Steven A. Shallcross, Chief Executive Officer and Chief Financial Officer	$	585,000	$	614,250
Frank Tufaro, Chief Operating Officer	$	375,000	$	393,750

2. Bonuses

The Compensation Committee believes that the granting of a bonus is appropriate to motivate the Named Executive Officers. The bonuses are to be rewarded in the discretion of the Compensation Committee and the Board of Directors, based on a review of achievements for the year. The Compensation Committee focuses on individual performance, which enables the Compensation Committee to differentiate among executives and emphasize the link between personal performance and compensation. The Compensation Committee also uses executive benchmarking information provided by Meridian in determining bonus amounts. Although the Compensation Committee does not use any fixed formula in determining bonuses, it does bonuses to objectives the Compensation Committee deems important such as for 2023, effective M&A strategy and implementation, financings, and achievement of clinical milestones.

Mr. Shallcross’ employment agreement provides that he was eligible for a target bonus of up to fifty percent (50%) of his base salary in cash. After considering Mr. Shallcross’ achievement relative to performance goals in 2023, the Compensation Committee approved a $350,000 cash bonus, or 114% of target.

Dr. Tufaro’s employment agreement provided that he was eligible for a target bonus of up to forty percent (40%) of his base salary in cash. Because he served only until May 10, 2023, Dr. Tufaro did not receive a cash bonus for 2023.

3. Long-Term Incentives

The Compensation Committee believes that a substantial portion of the Named Executive Officer’s compensation should be awarded in equity-based compensation since equity-based compensation is directly linked to the interests of stockholders. The Compensation Committee has elected to grant stock options to the Named Executive Officers and other key employees as the primary long-term incentive vehicle. In making this determination, the Compensation Committee considered a number of factors including: the accounting impact, potential value of stock option grants versus other equity instruments and cash incentives, and the alignment of equity participants with stockholders. The Compensation Committee determined to grant stock options to:

	·	enhance the link between the creation of stockholder value and executive compensation;

	·	provide an opportunity for equity ownership;

act as a retention tool; and

provide competitive levels of total compensation.

In 2023, the Compensation Committee approved grants of options exercisable for 28,000 shares to Mr. Shallcross. The options had a grant date of December 14, 2023, an exercise price of $14.75, vest pro rata on a monthly basis over 36 months and expire seven years from date of grant. Because he served only until May 10, 2023, Dr. Tufaro did not receive any equity-based compensation in 2023.

The Compensation Committee reviews the performance, potential burn rates and dilution levels to create an option pool that may be awarded to employee participants. Grants to the Named Executive Officers are determined by the Compensation Committee after reviewing market data, including the reports and analysis discussed above and after considering each executive’s performance, role and responsibilities.

The Compensation Committee does not seek to time equity grants to take advantage of information, either positive or negative, about our company that has not been publicly disclosed. Option grants are effective on the date the award determination is made by the Compensation Committee and the exercise price of options is the closing market price of our common stock on the business day of the grant or, if the grant is made on a weekend or holiday, on the prior business day.

4. Benefits

Named Executive Officers are eligible to participate in our standard medical, dental, vision, disability insurance, life insurance plans and other health and welfare plans provided to other full-time employees.

Each of our Named Executive Officers is entitled to participate in our 401(k) contributory defined contribution plan.

Pension Benefits

We do not currently provide pension arrangements or post-retirement health coverage for our employees, although we may consider such benefits in the future.

5. Retirement Benefits

Each of our Named Executive Officers is eligible to participate in our 401(k) contributory defined contribution plan. Pursuant to our 401(k) plan, all eligible employees, including our Named Executive Officers, are provided with a means of saving for their retirement. We currently match all participating employee contributions up to maximum of 4 percent of compensation which vest immediately.

6. Nonqualified Deferred Compensation

We do not provide any nonqualified deferred compensation plans to our employees, although we may consider such benefits in the future.

Conclusion

Attracting and retaining talented and motivated management and key employees is essential to creating long-term stockholder value. Offering a competitive, performance-based compensation program with a substantial equity component helps to achieve this objective by aligning the interests of the executive officers and other key employees with those of stockholders. We believe that our compensation program met these objectives and that our 2023 compensation program was appropriate in light of the challenges we and our employees face.

Risk Analysis of Our Compensation Program

Our Compensation Committee has reviewed our compensation policies as generally applicable to our employees and believes that our policies do not encourage excessive or inappropriate risk taking and that the level of risk that they do encourage is not reasonably likely to have a material adverse effect on us. As part of its assessment, the Compensation Committee considered, among other factors, the allocation of compensation among base salary and short- and long-term compensation, and our approach to establishing company-wide and individual financial, operational and other performance goals.

Outstanding Equity Awards at December 31, 2023

The table below reflects all outstanding equity awards made to each of the Named Executive Officers that were outstanding at December 31, 2023.

On January 3, 2022, we entered into a three-year employment agreement with Mr. Shallcross (the “2022 Shallcross Employment Agreement”), to serve as our Chief Executive Officer and to continue to serve as our Chief Financial Officer. The 2022 Employment Agreement replaced the prior employment agreement with us that Mr. Shallcross entered into on December 6, 2018, as amended December 5, 2019 (the “Amended Employment Agreement”). Mr. Shallcross has served as our Chief Financial Officer since June 1, 2015, initially pursuant to the terms of a two year employment agreement that we entered with him on April 28, 2015 (the “Initial Shallcross Employment Agreement”) and then pursuant to an employment agreement we entered into with him on December 6, 2018, which replaced the Initial Shallcross Agreement (the “Amended Shallcross Employment Agreement”). Mr. Shallcross does not receive additional compensation for service as our director. The material terms of the 2022 Shallcross Employment Agreement are set forth below.

Pursuant to the 2022 Employment Agreement, Mr. Shallcross was initially entitled to an annual base salary of $585,000 which was increased to $614,250 for the year ended December 31, 2023 and increased on December 14, 2023 to $644,963 to reflect a 5% merit increase. Mr. Shallcross is also eligible to receive an annual cash performance bonus targeted at fifty percent (50%) of his annual base salary as well as discretionary annual equity awards pursuant to the Company’s incentive plans. The annual bonus will be based upon the assessment of the Board of Mr. Shallcross’s performance. The 2022 Employment Agreement also includes confidentiality obligations and inventions assignments by Mr. Shallcross and non-solicitation and non-competition provisions.

The 2022 Employment Agreement has a stated term of three years but may be terminated earlier pursuant to its terms. If Mr. Shallcross’s employment is terminated for any reason, he or his estate as the case may be, will be entitled to receive the unpaid base salary through the date of termination and accrued vacation, any unpaid annual bonus earned with respect to any calendar year ending on or preceding the date of termination, expense reimbursement and any other entitlements accrued by him to the extent not previously paid (the “Accrued Obligations”); provided, however, that if his employment is terminated (i) by the us without Cause or by Mr. Shallcross for Good Reason (as each is defined in the Employment Agreement) then, subject to him executing a general release in form acceptable to the us that becomes effective, in addition to paying the Accrued Obligations, (a) we will continue to pay his then current base salary and if the Executive timely elects continued coverage under COBRA, the Company will continue to provide benefits at least equal to those that were provided at the time of termination for a period of twelve (12) months and (b) all unvested equity awards will vest and he shall have the right to exercise any such vested equity awards until the earlier of eighteen (18) months after termination or the remaining term of the awards; or (ii) by reason of his death or Disability (as defined in the Employment Agreement), then in addition to paying the Accrued Obligations, Mr. Shallcross or his estate would have the right to exercise any vested options until the earlier of six (6) months after termination or the remaining term of the awards. In such event, if Mr. Shallcross commenced employment with another employer and becomes eligible to receive medical or other welfare benefits under another employer-provided plan, the medical and other welfare benefits to be provided by the Company as described herein would terminate.

The 2022 Employment Agreement provides that upon the closing of a “Change in Control” (as defined in the 2022 Employment Agreement), all unvested options shall immediately vest and the time period that Mr. Shallcross will have to exercise all vested stock options and other awards that Mr. Shallcross may have will be equal to the shorter of: (i) eighteen (18) months after termination, or (ii) the remaining term of the award(s). If within one (1) year after the occurrence of a Change in Control, Mr. Shallcross terminates his employment for “Good Reason” or the Company terminates Mr. Shallcross’s employment for any reason other than death, disability or Cause, Mr. Shallcross will be entitled to receive: (i) the portion of his base salary for periods prior to the effective date of termination accrued but unpaid (if any); (ii) all unreimbursed expenses (if any); (iii) an aggregate amount (the “Change in Control Severance Amount”) equal to two (2) times the sum of his base salary plus an amount equal to the bonus that would be payable if the “target” level performance were achieved under the Company’s annual bonus plan (if any) in respect of the fiscal year during which the termination occurs (or the prior fiscal year if bonus levels have not yet been established for the year of termination) subject to him executing a general release in form acceptable to the Company that becomes effective. If within two (2) years after the occurrence of a Change in Control, Mr. Shallcross terminates his employment for “Good Reason” or the Company terminates Mr. Shallcross’s employment for any reason other than death, disability or Cause, Mr. Shallcross will be entitled to also receive for the period of two (2) consecutive years commencing on the date of such termination of his employment, medical, dental, life and disability insurance coverage for him and the members of his family that are not less favorable to him than the group medical, dental, life and disability insurance coverage carried by the Company for him subject to him executing a general release in form acceptable to the Company that becomes effective. The Change in Control Severance Amount is to be paid in a lump sum if the Change in Control event constitutes a “change in the ownership” or a “change in the effective control” of the Company or a “change in the ownership of a substantial portion of a corporation’s assets” (each within the meaning of Section 409A of the Internal Revenue Code (“Rule 409A”)), or in 48 substantially equal payments, if the Change in Control event does not so comply with Section 409A.

Frank Tufaro, Former Chief Operating Officer

On March 22, 2022, we entered into an employment agreement with Dr. Tufaro, as amended on December 15, 2022 (the “Employment Agreement”) to serve as the Chief Operating Officer of the Company, which agreement terminated on May 10, 2023. The material terms of the Employment Agreement are set forth below.

Pursuant to the Employment Agreement, as amended Dr. Tufaro was to receive an annual base salary of $393,750 and was eligible to earn an annual performance bonus targeted at forty percent (40%) of his annual base salary. The annual bonus was to be based upon the assessment of the Company’s Board of Dr. Tufaro’s performance and the Company’s attainment of targeted goals set by the Board. In addition, Dr. Tufaro was eligible to receive annual equity awards pursuant to the Company’s incentive equity plans: such awards (including the number and type of awards), if any, were at the sole discretion of the Board. The Employment Agreement also included confidentiality obligations and inventions assignments by Dr. Tufaro and non-solicitation and non-competition provisions.

The Employment Agreement had a stated term of three (3) years but could be terminated earlier pursuant to its terms. If Dr. Tufaro’s employment was terminated for any reason, he or his estate as the case may be, would be entitled to receive the accrued base salary, any unpaid annual bonus earned with respect to any calendar year ending on or preceding the date of termination, vacation pay, expense reimbursement and any other entitlements accrued by him to the extent not previously paid (the “Accrued Obligations”); provided, however, that if his employment was terminated (i) by the Company without Cause or by Dr. Tufaro for Good Reason (as each was defined in the Employment Agreement) then in addition to paying the Accrued Obligations, (a) the Company would continue to pay his then current base salary and continue to provide benefits at least equal to those that were provided at the time of termination for a period of six (6) months and (b) all unvested stock options and other equity awards would immediately vest and he would be entitled to exercise any vested equity awards until the earlier of six (6) months after termination or the remaining term of the awards; or (ii) by reason of his death or Disability (as defined in the Employment Agreement), then in addition to paying the Accrued Obligations, Dr. Tufaro, or his estate as the case may be, would have the right to exercise any vested options until the earlier of six (6) months after termination or the remaining term of the awards. If Dr. Tufaro commenced employment with another employer and became eligible to receive medical or other welfare benefits under another employer-provided plan, the medical and other welfare benefits to be provided by the Company as described herein would terminate.

Effective May 10, 2023, the Company entered into a Separation Agreement and Release (the “Separation Agreement”) and a consulting agreement (the “Consulting Agreement”) with Dr. Tufaro. Dr. Tufaro had entered into the Employment Agreement with the Company on March 22, 2022 to serve as our Chief Operating Officer.

In accordance with the terms of the Employment Agreement, the Separation Agreement provides for (i) the payment to Mr. Tufaro of a total of $196,875, paid in bi-monthly installments, less applicable withholding, for a period of six months, (ii) reimbursement of COBRA coverage for himself, his spouse and other eligible dependents for the lesser of: six months or until he commences new employment or substantial self-employment, (iii) acceleration of the vesting of his outstanding stock options (the “Option Awards”) and (iv) the extension of the period of time for which Mr. Tufaro has the right to exercise any vested shares subject to options until the earlier of (a) the expiration date of the Option Awards, or (b) six (6) months from the separation date. The Separation Agreement contains mutual general releases of claims and non-disparagement provisions.

The Consulting Agreement has a term of six months unless sooner terminated. Either party may terminate the Consulting Agreement without cause at any time upon thirty days’ prior written notice or with cause immediately. Mr. Tufaro will be compensated a set daily rate for each full day that he provides consulting services, pro-rated for any days services are provided less than eight hours.

Clawback Policy

The Board has adopted a clawback policy which allows us to recover performance-based compensation, whether cash or equity, from a current or former executive officer in the event of an Accounting Restatement. The clawback policy defines an Accounting Restatement as an accounting restatement of our financial statements due to our material noncompliance with any financial reporting requirement under the securities laws. Under such policy, we may recoup incentive-based compensation previously received by an executive officer that exceeds the amount of incentive-based compensation that otherwise would have been received had it been determined based on the restated amounts in the Accounting Restatement.

The Board has the sole discretion to determine the form and timing of the recovery, which may include repayment, forfeiture and/or an adjustment to future performance-based compensation payouts or awards. The remedies under the clawback policy are in addition to, and not in lieu of, any legal and equitable claims available to the Company.

PAY VERSUS PERFORMANCE

As required by Item 402(v) of Regulation S-K, we are providing the following information about the relationship between executive compensation actually paid and certain financial performance of the Company. For the most recently completed fiscal year, the Company did not use any “financial performance measures” as defined in Item 402(v) of Regulation S-K to link compensation paid to our Named Executive Officers, or NEOs, to the Company’s performance. We are also permitted to report as a “smaller reporting company” as defined under the U.S. federal securities laws. Accordingly, we have not included a tabular list of financial performance measures, and the table below does not include a column for a “Company-Selected Measure” as defined in Item 402(v) of Regulation S-K. For further information regarding our compensation philosophy and how we seek to align executive compensation with the Company’s performance, refer to “Executive Compensation”.

(1)

The dollar amounts reported are the amounts of total compensation reported for Steven A. Shallcross (our Chief Exeutive Officer and principal executive officer, or PEO) for each corresponding year in the “Total” column of the Summary Compensation Table. Refer to “Executive Compensation—Summary Compensation Table.”

(2)	The dollar amounts reported in column (c) represent the amount of “compensation actually paid” to Mr. Shallcross, as computed in accordance with Item 402(v) of Regulation S-K. The dollar amounts do not reflect the actual amount of compensation earned by or paid to Mr. Shallcross during the applicable year. In accordance with the requirements of Item 402(v) of Regulation S-K, the adjustments below were made to Mr. Shallcross' total compensation for each year to determine the compensation actually paid.

(3)	The dollar amounts reported represent the average of the amounts reported for the non-PEOs as a group (excluding our PEO) in the “Total” column of the Summary Compensation Table in each applicable year. Frank Tufaro was our only non-PEO (excluding our PEO) included for purposes of calculating the average amounts in 2022. For the years 2021 and 2020, we did not have any named executive officers other than our PEO.

(4)	The dollar amounts reported represent the average amount of “compensation actually paid” to the NEOs as a group (excluding our PEO), as computed in accordance with Item 402(v) of Regulation S-K. The dollar amounts do not reflect the actual average amount of compensation earned by or paid to the NEOs as a group (excluding our PEO) during the applicable year. In accordance with the requirements of Item 402(v) of Regulation S-K, the adjustments below were made to average total compensation for the NEOs as a group (excluding our PEO) for each year to determine the compensation actually paid, using the same methodology described above in Note (2).

(5)	Cumulative TSR is calculated by dividing the sum of the cumulative amount of dividends for the measurement period, assuming dividend reinvestment, and the difference between the Company’s share price at the end and the beginning of the measurement period by the Company’s share price at the beginning of the measurement period.

Analysis of the Information Presented in the Pay Versus Performance Table

As described in more detail above in “Executive Compensation–Narrative Disclosure to Summary Compensation Table,” the Company’s executive compensation program reflects a performance-driven compensation philosophy. While the Company utilizes several performance measures to align executive compensation with Company performance, those Company measures are not financial performance measures and are therefore not presented in the Pay Versus Performance table. Moreover, the Company generally seeks to incentivize long-term performance, and therefore does not specifically align the Company’s performance measures with “compensation actually paid” (as computed in accordance with Item 402(v) of Regulation S-K) for a particular year. In accordance with Item 402(v) of Regulation S-K, we are providing the following descriptions of the relationships between information presented in the Pay Versus Performance table above.

Compensation Actually Paid and Cumulative TSR

The chart below shows the relationship between the compensation actually paid to our PEO and the average compensation actually paid to our non-PEO NEOs, on the one hand, to the Company’s cumulative TSR over the three years presented in the table, on the other.

Compensation Actually Paid and Net Income

All information provided above under the heading “Pay Versus Performance” will not be deemed to be incorporated by reference into any filing of the Company under the Securities Act of 1933, as amended, or the Securities Exchange Act of 1934, as amended, whether made before or after the date hereof and irrespective of any general incorporation language in any such filing, except to the extent the Company specifically incorporates such information by reference.

PROPOSAL 3

APPROVAL OF AMENDMENTS TO THE COMPANY’S 2020 STOCK INCENTIVE PLAN

On July 30, 2020, the Board of Directors adopted, and on September 17, 2020 our stockholders approved, the Synthetic Biologics, Inc. 2020 Stock Incentive Plan (the “2020 Plan”). The 2020 Plan, as adopted, initially reserved an aggregate of 16,000 shares of Common Stock (which number has been adjusted to reflect prior reverse stock splits, including the 1-for-25 reverse stock split effected on August 26, 2024). The Board of Directors adopted, and the stockholders approved, an amendment to the 2020 Plan in 2022 to increase the shares available for issuance under the 2020 Plan to 280,000 shares (which number has been adjusted to reflect the 1-for-25 reverse stock split effected on August 26, 2024). As of September 27, 2024, there were (i) 112,640 shares of Common Stock available for grant under the 2020 Plan and (ii) 175,191 shares of Common Stock subject to awards were outstanding under the 2020 Plan, which numbers have been adjusted for the 1-for-25 reverse stock split effected on August 26, 2024.

In an effort to preserve cash and to attract, retain and motivate persons who make important contributions to our business, we would like to issue securities to our officers, directors and consultants. Management believes that the number of shares of Common Stock currently available for issuance under the 2020 Plan is insufficient to ensure it can meet its needs to provide for awards to the 2020 Plan participants for the next 12 months and that it may be insufficient in order to allow us the ability to compete successfully for talented employees and consultants.

The Board of Directors has approved, subject to stockholder approval, the amendment to the 2020 Plan (the “2020 Plan Amendment”) to increase by 2,220,000 the number of shares that may be granted under the 2020 Plan. The amendment to our 2020 Plan will (i) increase the number of shares of Common Stock with respect to which awards may be granted under the 2020 Plan from 280,000 shares of Common Stock (which number has been adjusted to reflect the reverse stock split effected on August 26, 2024) to 2,500,000 shares of Common Stock, and (ii) amend the number of shares of Common Stock with respect to which awards may be granted under the 2020 Plan to any non-employee director during any calendar year from 40,000 shares of Common Stock (which number has been adjusted to reflect the reverse stock split effected on August 26, 2024) to 250,000 shares of Common Stock.

Purpose of the 2020 Stock Incentive Plan

The Board of Directors believes that the proposed amendment to the 2020 Plan is necessary for us to attract, retain and motivate our employees, directors and consultants through the grant of stock options, stock appreciation rights, restricted stock, restricted stock units and other equity-based or equity-related awards. The Company believes the 2020 Plan is best designed to provide the proper incentives for our employees, directors and consultants, ensures our ability to make performance-based awards, and meets the requirements of applicable law. Additional individuals may be awarded awards under the 2020 Plan as consultants.

We manage our long-term stockholder dilution by limiting the number of equity incentive awards granted annually. The Board of Directors monitors our annual stock award Burn Rate, Dilution and Overhang (each as defined below), among other factors, in its efforts to maximize stockholders’ value by granting what, in the Board of Directors’ judgment, are the appropriate number of equity incentive awards necessary to attract, reward, and retain employees, consultants and directors. The table below illustrates our Burn Rate, Dilution, and Overhang for 2023, 2022, and 2021 with details of each calculation are noted below the table.

	2023			2022			2021
Burn Rate(1)		13.63	%		11.27	%		1.85	%
Dilution(2)		29.57	%		31.25	%		3.08	%
Overhang(3)		17.97	%		9.96	%		2.93	%

(1)

Burn Rate is (number of shares subject to equity awards granted during a fiscal year)/(weighted average shares outstanding for that fiscal year).

(2)

Dilution is (number of shares subject to equity awards + the number of shares available for future awards at the end of a fiscal year)/(number of shares outstanding at the end of the fiscal year + number of share subject to equity awards + number of shares available for future awards).

(3)

Overhang is (number of shares subject to equity awards at the end of a fiscal year)/(number of shares outstanding at the end of the fiscal year + number of shares subject to equity awards + number of shares available for future awards).

Limitation on Awards and Shares Available

The aggregate number of shares of Common Stock that we have authority to issue pursuant to stock awards under the 2020 Stock Incentive Plan is 280,000 shares. To date, we have issued options to purchase an aggregate of 167,360 shares of Common Stock under the 2020 Plan. As of September 27, 2024, there are 112,640 shares of Common Stock available for grants that may be made under the 2020 Plan. The 2020 Plan Amendment would increase the number of shares we have authority to issue pursuant to stock awards under the 2020 Stock Incentive Plan by 2,220,000 shares to 2,500,000 shares.

Summary of the 2020 Stock Incentive Plan

The following is a summary of the principal features of the 2020 Plan. This summary does not purport to be a complete description of all of the provisions of the 2020 Plan and it is qualified in its entirety by reference to the full text of the 2020 Plan, a copy of which has been filed as an exhibit to our Annual Report on Form 10-K for the year ended December 31, 2023 and the proposed amendment to the 2020 Plan is attached hereto as Appendix A.

Available Shares. Currently, an aggregate of 280,000 shares of the Company’s Common Stock may be issued under the 2020 Plan, subject to equitable adjustment in the event of stock splits and other capital changes, all of which may be issued in respect of Incentive Stock Options (or ISOs) that meet the requirements of Section 424(a) of the Code.

In applying the aggregate share limitation under the 2020 Plan, shares of Common Stock (i) subject to awards that are forfeited, cancelled, returned to or repurchased by the Company for failure to satisfy vesting requirements or otherwise forfeited, or terminated without payment being made thereunder and (ii) that are surrendered in payment or partial payment of the exercise price of an option or taxes required to be withheld with respect to the exercise of stock options or in payment with respect to any other form of award, are not counted and, therefore, may be made subject to new awards under the 2020 Plan.

Non-Employee Director Compensation Limit

Under the 2020 Plan, no more than 40,000 shares of Common Stock (which number has been adjusted to reflect the reverse stock split effected on August 26, 2024) may be subject to stock awards granted under the 2020 Plan during any one calendar year to any non-employee director. The 2020 Plan Amendment would adjust the number of shares of Common Stock with respect to which awards may be granted under the 2020 Plan to any non-employee director during any calendar year from 40,000 shares of Common Stock to 250,000 shares of Common Stock.

Administration. The 2020 Plan is administered by the Compensation Committee of our Board of Directors (the “Compensation Committee”). The Compensation Committee has discretion to determine the individuals to whom awards may be granted under the 2020 Plan, the number of shares of Common Stock, units or other rights subject to each award, the type of award, the manner in which such awards will vest, and the other conditions applicable to awards. The Compensation Committee is authorized to interpret the 2020 Plan, to prescribe, amend and rescind any rules and regulations relating to the 2020 Plan and to make any other determinations necessary or desirable for the administration of the 2020 Plan. All interpretations, determinations and actions by the Compensation Committee are final, conclusive and binding on all parties.

Eligibility. Any employee, officer, director, consultant, advisor or other individual service provider of the Company or any of its subsidiaries, or any person who is determined by our Compensation Committee to be a prospective employee, officer, director, consultant, advisor or other individual service provider of the Company or any of its subsidiaries is eligible to participate in the 2020 Plan. As of September 27, 2024, the Company had approximately 23 full-time employees, including 1 executive officer, 3 non-employee directors, and 4 consultants, advisors and/or other individual service providers. As of September 27, 2024, no person is eligible to participate as a result of a determination by the Compensation Committee that that person is a prospective employee, director or consultant of our Company or any of our subsidiaries. As awards under the 2020 Plan are within the discretion of the Compensation Committee, we cannot determine how many individuals in each of the categories described above will receive awards.

Types of Awards. Under the 2020 Plan, the Compensation Committee may grant nonqualified stock options (or NSOs), incentive stock options (or ISOs), stock appreciation rights (or SARs), restricted stock, stock units, performance shares, performance units, other cash-based awards and other stock- based awards. The terms of each award will be set forth in a written agreement with the recipient.

Stock Options. The Compensation Committee will determine the exercise price and other terms for each option and whether the options will be NSOs or ISOs. The exercise price per share of each option will not be less than 100% of the fair market value of the Company’s Common Stock on the date of grant or, if there are no trades on such date, then the closing price of a share of our Common Stock on the most recent date preceding the date of grant on which shares of Common Stock were publicly traded (or 110% of the fair market value per share in the case of ISOs granted to a ten-percent or more shareholder). However, if permissible under law and the rules of the exchange on which the Company is listed, options to participants who are not residents of the U.S. may be granted at a price below fair market value on the date of grant. On September 27, 2024, the closing sale price of a share of our Common Stock on the NYSE American was $[·].

ISOs may be granted only to employees and are subject to certain other restrictions. To the extent an option intended to be an ISO does not qualify as an ISO, it will be treated as a nonqualified option.

A participant may exercise an option by written notice and payment of the exercise price in cash, or, as determined by the Compensation Committee, through delivery of previously owned shares, the withholding of shares deliverable upon exercise, a cashless exercise program implemented by the Compensation Committee in connection with the 2020 Plan, and/or such other method as approved by the Compensation Committee and set forth in an award agreement. The maximum term of any option granted under the 2020 Plan is ten years from the date of grant (five years in the case of an ISO granted to a ten-percent or more shareholder). The Compensation Committee may, in its discretion, permit a holder of an NSO to exercise the option before it has otherwise become exercisable, in which case the shares of the Company’s Common Stock issued to the recipient will be restricted stock having analogous vesting restrictions to the unvested NSO before exercise.

No option may be exercisable for more than ten years (five years in the case of an ISO granted to a ten-percent or more shareholder) from the date of grant. Options granted under the 2020 Plan will be exercisable at such time or times as the Compensation Committee prescribes at the time of grant. No employee may receive ISOs that first become exercisable in any calendar year in an amount exceeding $100,000.

Unless an award agreement provides otherwise, if a participant’s Service (as defined in the 2020 Plan) terminates (i) by reason of his or her death or Disability (as defined in the 2020 Plan), any option held by such participant may be exercised, to the extent otherwise exercisable, by the participant or his or her estate or personal representative, as applicable, at any time in accordance with its terms for up to one year after the date of such participant’s death or termination of Service, as applicable, (ii) for Cause (as defined in the 2020 Plan), any option held by such participant will be forfeited and cancelled as of the date of termination of Service and (iii) for any reason other than death, Disability or Cause, any option held by such participant may be exercised, to the extent otherwise exercisable, up until ninety (90) days following termination of Service.

Stock Appreciation Rights. The Compensation Committee may grant SARs on a basis that allows for the exercise of the right by the Participant or that provides for the automatic payment of the right upon a specified date or event. The Compensation Committee will determine the other terms applicable to SARs. The base price per share of each SAR will not be less than 100% of the closing price of a share of the Company’s Common Stock on the date of grant or, if there are no trades on such date, then the closing price of a share of the Company’s Common Stock on the most recent date preceding the date of grant on which shares of Common Stock were publicly traded. The maximum term of any SAR granted under the 2020 Plan will be ten years from the date of grant. Generally, each SAR will entitle a participant upon exercise to an amount equal to the excess of the fair market value on the exercise date of one share of our Common Stock over the base price, multiplied by the number of shares of Common Stock as to which the SAR is exercised. Payment may be made in shares of Company Common Stock, in cash, or partly in shares of Company Common Stock and partly in cash, all as determined by the Compensation Committee.

Restricted Stock and Stock Units. The Compensation Committee may award restricted common stock and/or stock units under the 2020 Plan. Restricted stock awards consist of shares of stock that are transferred to a participant subject to restrictions that may result in forfeiture if specified conditions are not satisfied. Stock units confer the right to receive shares of the Company’s Common Stock, cash, or a combination of shares and cash, at a future date upon or following the attainment of certain conditions specified by the Compensation Committee, subject to applicable tax withholding requirements. The Compensation Committee will determine the restrictions and conditions applicable to each award of restricted stock or stock units, which may include performance-based conditions. Unless the Compensation Committee determines otherwise at the time of grant, holders of restricted stock will have the right to vote the shares and receive all dividends and other distributions.

Performance Shares and Performance Units. The Compensation Committee may award performance shares and/or performance units under the 2020 Plan. Performance shares and performance units are awards, payable in shares of the Company’s Common Stock, cash or a combination thereof, which are earned during a specified time period subject to the attainment of performance goals, as established by the Compensation Committee. The Compensation Committee will determine the restrictions and conditions applicable to each award of performance shares and performance units.

Incentive Bonus Awards. The Compensation Committee may award incentive bonus awards payable in cash or shares of common stock, as set forth in an award agreement. Incentive bonus awards may be based upon the attainment of specified levels of Company or subsidiary performance. The amount of an incentive bonus award to be paid upon the attainment of each targeted level of performance will equal a percentage of a participant’s base salary for the fiscal year, a fixed dollar amount or such other formula, as determined by the Compensation Committee. The Compensation Committee will determine the terms and conditions applicable to each incentive bonus award.

Other Stock-Based and Cash-Based Awards. The Compensation Committee may award other types of stock-based or cash-based awards under the 2020 Plan, including the grant or offer for sale of unrestricted shares of the Company’s Common Stock, in such amounts and subject to such terms and conditions as the Compensation Committee determines.

Transferability. Awards granted under the 2020 Plan will not be transferable other than by will or by the laws of descent and distribution, except that the Compensation Committee may permit NSOs, share-settled SARs, restricted stock, performance share or share-settled other stock-based awards to be transferred to immediate family members and/or for estate planning or charitable purposes.

Change in Control. The Compensation Committee may, at the time of the grant of an award, provide for the effect of a Change in Control (as defined in the 2020 Plan) on any award, including (i) accelerating or extending the time periods for exercising, vesting in, or realizing gain from any award, (ii) eliminating or modifying the performance or other conditions of an award, (iii) providing for the cash settlement of an award for an equivalent cash value, as determined by the Compensation Committee, or (iv) such other modification or adjustment to an award as the Compensation Committee deems appropriate to maintain and protect the rights and interests of participants upon or following a Change in Control. Unless otherwise provided by an award agreement, the Compensation Committee may, in its discretion and without the need for the consent of any recipient of an award, also take one or more of the following actions contingent upon the occurrence or in anticipation of a Change in Control: (a) cause any or all outstanding options and SARs to become immediately exercisable, in whole or in part; (b) cause any other awards to become non-forfeitable, in whole or in part; (c) cancel any option or SAR in exchange for a substitute option and/or SAR; (d) cancel any award of restricted stock, stock units, performance shares or performance units in exchange for a similar award of the capital stock of any successor corporation; (e) redeem any restricted stock for cash and/or other substitute consideration with a value equal to the fair market value of an unrestricted share of the Company’s Common Stock on the date of the Change in Control; or (f) terminate any award in exchange for an amount of cash and/or property equal to the amount, if any, that would have been attained upon the exercise of such award or realization of the participant’s rights as of the date of the occurrence of the Change in Control (the “Change in Control Consideration”); provided, however that if the Change in Control Consideration with respect to any option or SAR does not exceed the exercise price of such option or SAR, the Compensation Committee may cancel the option or SAR without payment of any consideration therefor. Any such Change in Control Consideration may be subject to any escrow, indemnification and similar obligations, contingencies and encumbrances applicable in connection with the Change in Control to holders of the Company’s Common Stock. Without limitation of the foregoing, if as of the date of the occurrence of the Change in Control the Compensation Committee determines that no amount would have been attained upon the realization of the participant’s rights, then such award may be terminated by the Company without payment. The Compensation Committee may cause the Change in Control Consideration to be subject to vesting conditions (whether or not the same as the vesting conditions applicable to the award prior to the Change in Control) and/or make such other modifications, adjustments or amendments to outstanding Awards or the 2020 Plan as the Compensation Committee deems necessary or appropriate.

Term; Amendment and Termination. No award may be granted under the 2020 Plan on or after July 30, 2030. The Board of Directors may suspend or terminate the 2020 Plan (or any portion thereof) at any time and may amend the 2020 Plan at any time and from time to time in such respects as the Board of Directors may deem advisable or in the best interests of the Company or any subsidiary, provided, however, that (i) no amendment, suspension or termination may materially impair the rights of a participant under any awards previously granted, without his or her consent, (ii) the Company shall obtain stockholder approval of any 2020 Plan amendment as required to comply with any applicable law, regulation or stock exchange rule and (iii) stockholder approval is required for any amendment to the 2020 Plan that (x) increases the number of shares of common stock available for issuance thereunder or (y) changes the persons or class of persons eligible to receive awards.

New Plan Benefits

The grant of options and other awards under the 2020 Plan is discretionary, and we cannot determine now the number or type of options or other awards to be granted in the future to any particular person or group.

Since it is not possible to determine the exact number of awards that will be granted under the 2020 Plan, the awards granted during 2023 under the 2020 Plan are set forth in the following table.

Name and position	Number of Stock Options
Steven A. Shallcross, Chief Executive Officer, Chief Financial Officer and Director		28,000
Frank Tufaro, Chief Operating Officer		0
All Current Executive Officers as a Group (two (2) persons)		28,000
All Current Non-Executive Directors as a Group (three (3) persons)		13,200
All Employees, including our current officers who are not Executive Officers, as a group		46,600

U.S. Federal Income Tax Consequences

The following is a brief summary of the general U.S. federal income tax consequences relating to the 2020 Plan. This summary is based on U.S. federal tax laws and regulations in effect on the date of this Proxy Statement and does not purport to be a complete description of the U.S. federal income tax laws.

Incentive Stock Options. Incentive stock options are intended to qualify for special treatment available under Section 422 of the Internal Revenue Code. A participant who is granted an incentive stock option will not recognize ordinary income at the time of grant. A participant will not recognize ordinary income upon the exercise of an incentive stock option provided that the participant was, without a break in service, an employee of the Company or a subsidiary during the period beginning on the grant date of the option and ending on the date three months prior to the date of exercise (one year prior to the date of exercise if the participant’s employment is terminated due to permanent and total disability).

If the participant does not sell or otherwise dispose of the shares of Common Stock acquired upon the exercise of an incentive stock option within two years from the grant date of the incentive stock option or within one year after he or she receives the shares of Common Stock, then, upon disposition of such shares of Common Stock, any amount recognized in excess of the exercise price will be taxed to the participant as a capital gain. The participant will generally recognize a capital loss to the extent that the amount recognized is less than the exercise price.

If the foregoing holding period requirements are not met, the participant will generally recognize ordinary income at the time of the disposition of the shares of Common Stock in an amount equal to the lesser of (i) the excess of the fair market value of the shares of Common Stock on the date of exercise over the exercise price or (ii) the excess, if any, of the amount recognized upon disposition of the shares of Common Stock over the exercise price. Any amount recognized in excess of the value of the shares of Common Stock on the date of exercise will be capital gain. If the amount recognized is less than the exercise price, the participant generally will recognize a capital loss equal to the excess of the exercise price over the amount recognized upon the disposition of the shares of Common Stock.

The rules described above that generally apply to incentive stock options do not apply when calculating any alternative minimum tax liability. The rules affecting the application of the alternative minimum tax are complex, and their effect depends on individual circumstances, including whether a participant has items of adjustment other than those derived from incentive stock options.

Nonqualified Stock Options. A participant will not recognize ordinary income when a nonqualified stock option is granted. When a nonqualified stock option is exercised, a participant will recognize ordinary income in an amount equal to the excess, if any, of the fair market value of the shares of Common Stock that the participant purchased over the exercise price he or she paid.

Stock Appreciation Rights. A participant will not recognize ordinary income when a SAR is granted. When a SAR is exercised, the participant will recognize ordinary income equal to the cash and/or the fair market value of shares of Common Stock the participant receives.

Restricted Shares. A participant who has been granted restricted shares will not recognize ordinary income at the time of grant, assuming that the underlying shares of Common Stock are not transferable and that the restrictions create a “substantial risk of forfeiture” for federal income tax purposes and that the participant does not make an election under Section 83(b) of the Internal Revenue Code. Generally, upon the vesting of restricted shares, the participant will recognize ordinary income in an amount equal to the then fair market value of the shares of Common Stock, less any consideration paid for such shares of Common Stock. Any gains or losses recognized by the participant upon disposition of the shares of Common Stock will be treated as capital gains or losses. However, a participant may elect, pursuant to Section 83(b) of the Internal Revenue Code, to have income recognized at the date of grant of a restricted share award equal to the fair market value of the shares of Common Stock on the grant date (less any amount paid for the restricted shares) and to have the applicable capital gain holding period commence as of that date.

Restricted Share Units. A participant generally will not recognize ordinary income when restricted share units are granted. Instead, a participant will recognize ordinary income when the restricted share units are settled in an amount equal to the fair market value of the shares of Common Stock or the cash he or she receives, less any consideration paid.

Sale of Shares. When a participant sells shares of Common Stock that he or she has received under an award, the participant will generally recognize long-term capital gain or loss if, at the time of the sale, the participant has held the shares of Common Stock for more than one year (or, in the case of a restricted share award, more than one year from the date the restricted shares vested unless the participant made an election pursuant to Section 83(b) of the Internal Revenue Code, described above). If the participant has held the shares of Common Stock for one year or less, the gain or loss will be a short-term capital gain or loss.

Section 409A of the Tax Code. In 2004, the Internal Revenue Code was amended to add Section 409A, which created new rules for amounts deferred under nonqualified deferred compensation plans. Section 409A includes a broad definition of nonqualified deferred compensation plans which may extend to various types of awards granted under the 2020 Plan. If an award is subject to, but fails to comply with, Section 409A, the participant would generally be subject to accelerated income taxation, plus a penalty tax and an interest charge. The Company intends that awards granted under the 2020 Plan will either be exempt from, or will comply with, Section 409A.

Tax Deductibility of Compensation Provided Under the 2020 Plan. When a participant recognizes ordinary compensation income as a result of an award granted under the 2020 Plan, the Company may be permitted to claim a federal income tax deduction for such compensation, subject to various limitations that may apply under applicable law.

Further, to the extent that compensation provided under the 2020 Plan may be deemed to be contingent upon a change in control of the Company, a portion of such compensation may be non-deductible by the Company under Section 280G of the Internal Revenue Code and may be subject to a 20% excise tax imposed on the recipient of the compensation.

Interests of Directors and Executive Officers

Our directors and executive officers have substantial interests in the matters set forth in this proposal regarding the proposed 2020 Plan Amendment since equity awards may be granted to them under the 2020 Plan.

Vote Required

Approval of the 2020 Plan Amendment included as Appendix A requires the affirmative vote of a majority of the shares of Common Stock present in person or represented by proxy and entitled to vote on this matter at the 2024 Annual Meeting of Stockholders.

THE BOARD OF DIRECTORS UNANIMOUSLY RECOMMENDS THAT YOU VOTE “FOR” THE AMENDMENT TO THE COMPANY’S 2020 PLAN TO INCREASE THE NUMBER OF SHARES OF COMMON STOCK AVAILABLE THAT WE WILL HAVE AUTHORITY TO GRANT.

PROPOSAL 4

APPROVAL OF AN AMENDMENT TO THE COMPANY’S ARTICLES OF INCORPORATION TO INCREASE THE NUMBER OF AUTHORIZED SHARES OF COMMON STOCK

Our Board of Directors has unanimously approved an amendment to our Articles of Incorporation to increase the number of shares of authorized Common Stock from 14,000,000 shares to 350,000,000 shares, as further described below. The number of authorized shares was decreased in connection with the reverse stock split effected August 26, 2024. If approved, the Authorized Common Stock Increase would be effected by amending Article 3 of our Articles of Incorporation to reflect the Authorized Common Stock Increase which would restore the authorized number of shares of Common Stock to the pre-August 26, 2024 reverse stock split authorized number. The full text of the proposed certificate of change to amend Article 3 of our Articles of Incorporation is attached to this Proxy Statement as Appendix B.

The Board of Directors proposes and recommends increasing the number of shares of authorized Common Stock from the 14,000,000 shares that are authorized for issuance pursuant to our Articles of Incorporation to a total of 350,000,000 shares of Common Stock. The chart below illustrates the number of shares of Common Stock that will be available for issuance if the Authorized Common Stock Increase is effected. The number of shares disclosed in the column “Estimated Number of Shares of Common Stock after the Increase” gives further effect to the Authorized Common Stock Increase in the number of authorized shares of Common Stock from 14,000,000 to 350,000,000.

	ESTIMATED NUMBER OF SHARES OF COMMON STOCK BEFORE INCREASE		ESTIMATED NUMBER OF SHARES OF COMMON STOCK AFTER THE INCREASE(3)
Authorized		14,000,000		350,000,000
Outstanding		1,353,862		1,353,862
Issuable upon exercise of outstanding warrants and options		175,191		175,191
Reserved for issuance⁽¹⁾		112,640		2,332,640
Authorized but unissued⁽²⁾		12,358,307		346,138,307

(1)

Shares reserved for future issuance under our existing equity incentive plans, excluding shares issuable under outstanding stock options.

(2)

Shares authorized but unissued represent Common Stock available for future issuance beyond shares currently outstanding, shares issuable under outstanding warrants and stock options, and shares reserved for issuance under equity incentive plans.

(3)

Assumes the 2020 Plan Amendment is approved by stockholders.

The Board of Directors believes that the Authorized Common Stock Increase is advisable and in our stockholders’ best interests. The Authorized Common Stock Increase will provide us with flexibility in completing financing and capital raising transactions, which may be necessary for us to execute our future business plans.

We anticipate that we may issue additional shares of Common Stock in the future in connection with one or more of the following:

• financing transactions, such as public or private offerings of Common Stock or convertible securities;

• partnerships, collaborations and other similar transactions;

• our equity incentive plans;

• strategic investments; and

• other corporate purposes that have not yet been identified.

The availability of additional shares of Common Stock for issuance is, in management’s view, prudent and will afford us flexibility in acting upon financing transactions to strengthen our financial position and/or commercial partnership opportunities that may arise and aid in meeting the NYSE American stockholders’ equity requirements. Other possible business and financial uses for the additional shares of Common Stock include, without limitation, potential strategic transactions, including, among other things, acquisitions, strategic partnerships, joint ventures, restructurings, business combinations and investment. As of the Record Date, we have approximately 112,640 authorized shares of Common Stock available for future issuance. We do not believe that this is sufficient to meet our future equity financing requirements. We currently have no agreements with any third parties for the sale of our securities. Although at this time, we do not have any plans, commitments, proposals, arrangements, understandings or agreements regarding the issuance of Common Stock other than issuances upon exercise or conversion of currently outstanding securities; we anticipate seeking future equity financing opportunities and will evaluate opportunities that are presented to us. We believe that the Authorized Common Stock Increase will help ensure that we have sufficient authorized shares available for issuance to allow us to pursue equity financings if the Board of Directors determines that it would be in our best interests based on our working capital needs and prevailing market conditions.

We believe that the additional authorized shares would enable us to act quickly in response to opportunities that may arise for these types of transactions, in most cases without the necessity of obtaining further stockholder approval and holding a special stockholders’ meeting before such issuance(s) could proceed, except as provided under Nevada law or under applicable NYSE American rules.

Possible Effects of the Authorized Common Stock Increase

The newly authorized shares of Common Stock will have all the powers, preferences, and rights of the shares of Common Stock presently authorized. Therefore, approval of the Authorized Common Stock Increase and any subsequent issuance of additional shares of Common Stock would not affect a current common stockholder’s rights as a stockholder, except for any dilutive effects of a potential increase in the number of outstanding shares of Common Stock to, among other things, earnings per share, book value per share, and the voting power of current holders of our Common Stock. The Authorized Common Stock Increase would not have any immediate dilutive effect on the proportionate voting power or other rights of existing stockholders until additional shares are issued.

As is true for shares presently authorized but unissued, the future issuance of Common Stock authorized by the Authorized Common Stock Increase may, among other things, decrease existing stockholders’ percentage equity ownership and, depending on the price at which they are issued, could be dilutive to the voting rights of existing stockholders and have a negative effect on the market price of the Common Stock.

Potential Anti-takeover Effects of the Authorized Common Stock Increase

Release No. 34-15230 of the staff of the SEC requires disclosure and discussion of the effects of any action, including the proposals discussed herein, that may be used as an anti-takeover mechanism. Since the Authorized Common Stock Increase will provide that the number of authorized shares of Common Stock will be 350,000,000, the Authorized Common Stock Increase, if effected, will result in a relative increase in the number of authorized but unissued shares of our Common Stock vis-à-vis the outstanding shares of our Common Stock and, could, under certain circumstances, have an anti-takeover effect, although this is not the purpose or intent of our Board of Directors. A relative increase in the number of authorized shares of Common Stock could have other effects on our stockholders, depending upon the exact nature and circumstances of any actual issuances of authorized but unissued shares. A relative increase in our authorized shares could potentially deter takeovers, including takeovers that our Board of Directors has determined are not in the best interest of our stockholders, in that additional shares could be issued (within the limits imposed by applicable law and the NYSE American) in one or more transactions that could make a change in control or takeover more difficult. For example, we could issue additional shares without further stockholder approval so as to dilute the stock ownership or voting rights of persons seeking to obtain control without our agreement. Similarly, the issuance of additional shares to certain persons allied with our management could have the effect of making it more difficult to remove our current management by diluting the stock ownership or voting rights of persons seeking to cause such removal. The Authorized Common Stock Increase therefore may have the effect of discouraging unsolicited takeover attempts. By potentially discouraging initiation of any such unsolicited takeover attempts, the Authorized Common Stock Increase may limit the opportunity for our stockholders to dispose of their shares at the higher price generally available in takeover attempts or that may be available under a merger proposal.

We have not proposed the increase in the number of authorized shares of Common Stock with the intention of using the additional authorized shares for anti-takeover purposes, but we would be able to use the additional shares to oppose a hostile takeover attempt or delay or prevent changes in our control or our management. Although the Authorized Common Stock Increase has been prompted by business and financial considerations and not by the threat of any known or threatened hostile takeover attempt, stockholders should be aware that the effect of the Authorized Common Stock Increase could facilitate future attempts by us to oppose changes in our control and perpetuate our management, including transactions in which the stockholders might otherwise receive a premium for their shares over then current market prices. We cannot provide assurances that any such transactions will be consummated on favorable terms or at all, that they will enhance stockholder value, or that they will not adversely affect our business or the trading price of the Common Stock.

Consequences if Stockholder Approval for Proposal Is Not Obtained

If stockholder approval for this Proposal 4 is not obtained, we will not be able to file a certificate of change to amend our Articles of Incorporation to effect the Authorized Common Stock Increase, and our limited number of authorized shares of the Common Stock that are neither outstanding nor reserved for issuance could adversely affect our ability to raise capital through equity financings or engage in acquisitions or other transactions.

Interests of Directors and Executive Officers

Our directors and executive officers have no substantial interests, directly or indirectly, in the matters set forth herein regarding the proposed Authorized Common Stock Increase except to the extent of their ownership of shares of our Common Stock and any additional shares of Common Stock that will be available for grant under the 2020 Plan.

Vote Required to Approve the Authorized Common Stock Increase

Approval of the certificate of change to our Articles of Incorporation included as Appendix B, and to authorize our Board of Directors to effect the Authorized Common Stock Increase, requires an affirmative vote of a majority of the voting power of the Common Stock.

Recommendation

OUR BOARD OF DIRECTORS UNANIMOUSLY RECOMMENDS THAT YOU VOTE “FOR” APPROVAL OF THE AMENDMENT TO THE COMPANY’S ARTICLES OF INCORPORATION TO INCREASE THE NUMBER OF AUTHORIZED SHARES OF COMMON STOCK.

PROPOSAL 5

THE ADJOURNMENT OF THE ANNUAL MEETING

Background of and Rationale for the Adjournment Proposal

Our stockholders are being asked to consider and vote upon an adjournment of the 2024 Annual Meeting of Stockholders, if necessary, to solicit additional proxies if there are not sufficient votes in favor Proposal 3 and/or Proposal 4.

In the Adjournment Proposal, we are asking stockholders to authorize the holder of any proxy solicited by the Board to vote in favor of adjourning or postponing the 2024 Annual Meeting of Stockholders or any adjournment or postponement thereof. If our stockholders approve this proposal, we could adjourn or postpone the 2024 Annual Meeting of Stockholders, and any adjourned session of the 2024 Annual Meeting of Stockholders, to use the additional time to solicit additional proxies in favor of Proposal 3 and/or Proposal 4.

Additionally, approval of the Adjournment Proposal could mean that, in the event we receive proxies indicating that holders of a majority of the number of shares present in person or represented by proxy at the 2024 Annual Meeting of Stockholders will vote against Proposal 3 and/or Proposal 4, we could adjourn or postpone the 2024 Annual Meeting of Stockholders without a vote on Proposal 3 and/or Proposal 4 and use the additional time to solicit the holders of those shares to change their vote in favor of Proposal 3 and/or Proposal 4.

Vote Required

Approval of the adjournment of the 2024 Annual Meeting of Stockholders requires an affirmative vote of holders of a majority of the shares of Common Stock present in person or represented by proxy and entitled to vote on this matter at the 2024 Annual Meeting of Stockholders.

THE BOARD OF DIRECTORS UNANIMOUSLY RECOMMENDS A VOTE “FOR”

APPROVAL OF THE ADJOURNMENT PROPOSAL.

ANNUAL REPORT/FORM 10-K

Theriva’s Annual Report on Form 10-K for the fiscal year ended December 31, 2023 is being mailed to stockholders concurrently with this Proxy Statement. Copies of the Annual Report on Form 10-K for the fiscal year ended December 31, 2023 and any amendments thereto, as filed with the SEC, may be obtained without charge by writing to Theriva Biologics, Inc., 9605 Medical Center Drive, Suite 270, Rockville, Maryland 20850, Attention: Corporate Secretary. A complimentary copy may also be obtained at the internet website maintained by the SEC at www.sec.gov, and by visiting our internet website at www.therivabio.com.

NOTICE REGARDING DELIVERY OF STOCKHOLDER DOCUMENTS

(“HOUSEHOLDING” INFORMATION)

The SEC has adopted rules that permit companies and intermediaries (e.g., brokers) to satisfy the delivery requirements for proxy statements and annual reports by delivering a single copy of these materials to an address shared by two or more Theriva stockholders. This process, which is commonly referred to as “householding,” potentially means extra convenience for stockholders and cost savings for companies and intermediaries. A number of brokers and other intermediaries with account holders who are our stockholders may be householding our proxy materials, including this Proxy Statement. In that event, a single proxy statement, as the case may be, will be delivered to multiple stockholders sharing an address unless contrary instructions have been received from the affected stockholders. Once you have received notice from your broker or other intermediary that it will be householding communications to your address, householding will continue until you are notified otherwise or until you revoke your consent, which is deemed to be given unless you inform the broker or other intermediary otherwise when you receive or received the original notice of householding. If, at any time, you no longer wish to participate in householding and would prefer to receive a separate proxy statement, please notify your broker or other intermediary to discontinue householding and direct your written request to receive a separate proxy statement and other annual meeting materials to us at: Theriva Biologics, Inc., Attention: Corporate Secretary, 9605 Medical Center Drive, Suite 270, Rockville, Maryland 20850 or by calling us at (301) 417-4364. Stockholders who currently receive multiple copies of the proxy statement at their address and would like to request householding of their communications should contact their broker or other intermediary.
