to Be Held on June 16, 2023. The Company’s Proxy Statement and Annual Report, provided to Stockholders

You are receiving this Proxy Statement because you owned shares of common stock, par value $0.005 (“common stock”), of Eterna Therapeutics Inc., a Delaware corporation (the “Company”), as of April 26, 2023, which entitles you to vote those shares at our 2023 Annual Meeting of stockholders (including any adjournments of or postponements thereof, the “Annual Meeting”) to be held on June 16, 2023, at 11:00 a.m. Eastern Time. The Annual Meeting will be a completely virtual meeting of stockholders conducted via live audio webcast. You will be able to attend the Annual Meeting by visiting virtualshareholdermeeting.com/ERNA2023. Our Board of Directors (the “Board”) is soliciting proxies from stockholders who wish to vote their shares at the Annual Meeting. By using a proxy, you can vote even if you do not attend the Annual Meeting. This proxy statement (this “Proxy Statement”) describes and provides information about the matters on which you are being asked to vote so that you can make an informed decision. Eterna Therapeutics Inc. is referred to in this document as Eterna, we, us, our and the Company.

The Notice of Internet Availability of Proxy Materials (the “Notice”), Proxy Statement and form of proxy are first being distributed and made available on the Internet on or about May 2, 2023. Stockholders should review the information contained in this Proxy Statement together with our 2022 Annual Report, which accompanies this Proxy Statement.

Our Internet website and the information contained therein or linked thereto are not incorporated by reference or otherwise made a part of this Proxy Statement.

The Annual Meeting will be held on June 16, 2023, at 11:00 a.m. Eastern Time. The Annual Meeting will be a virtual meeting of stockholders to be held solely as a live webcast over the Internet at virtualshareholdermeeting.com/ERNA2023. There will still not be a physical location for the Annual Meeting.

We are leveraging technology to hold a virtual Annual Meeting that expands convenient access to, and enables participation by, stockholders from any location around the world. We believe the virtual format encourages attendance and participation by a broader group of stockholders, while also reducing the costs and environmental impact associated with an in-person meeting.

Stockholders of record as of April 26, 2023 (which we refer to as the record date), or their duly appointed proxies, and our invited guests are permitted to attend the Annual Meeting.

The Annual Meeting will be a completely virtual meeting of stockholders conducted exclusively via live audio webcast. You will be able to attend the Annual Meeting by visiting virtualshareholdermeeting.com/ERNA2023. To participate in the Annual Meeting, you will need the 16-digit control number included on your Notice, proxy card, or voting instruction form. The Annual Meeting will begin promptly at 11:00 a.m. Eastern Time on June 16, 2023. We encourage you to access the virtual meeting website prior to the start time. Online check-in will begin at 10:45 a.m. Eastern Time, and you should allow ample time to ensure your ability to access the meeting.

We will hold our question and answer session with management immediately following the conclusion of the business to be conducted at the Annual Meeting.

You may submit a question at any time during the meeting by visiting virtualshareholdermeeting.com/ERNA2023. The Chairman of the meeting has broad authority to conduct the Annual Meeting in an orderly manner, including establishing rules of conduct. A replay of the Annual Meeting will be available on our website at https://www.eternatx.com after the meeting.

The Annual Meeting will be held for the following purposes:

You may vote your shares electronically at the Annual Meeting by using the control number on your Notice, proxy card, or voting instruction form and following the instructions at www.proxyvote.com. If you have already voted previously by telephone or Internet, there is no need to vote again at the Annual Meeting unless you wish to revoke and change your vote.

For beneficial stockholders with shares registered in the name of a brokerage firm or bank, a number of brokerage firms and banks are participating in a program that offers telephone and Internet voting options. Stockholders should refer to the voting instruction form provided by their brokerage firm or bank for instructions on the voting methods they offer. Registered stockholders with shares registered directly in their names with our transfer agent, Computershare Trust Company, N.A (“Computershare”), will also be able to vote by telephone and Internet. If your shares are held in an account at a brokerage firm or bank participating in this program or registered directly in your name with Computershare, then you may vote those shares by calling the telephone number specified on your proxy card or accessing the Internet website address specified on your proxy card instead of completing and signing the proxy itself. Submitting a telephonic or Internet proxy will not affect your right to vote electronically at the Annual Meeting should you decide to attend the Annual Meeting. The telephone and Internet voting procedures are designed to authenticate stockholders’ identities, to allow stockholders to give their voting instructions, and to confirm that stockholders’ instructions have been recorded properly.

The accompanying proxy card provides instructions on how to vote via the Internet or by telephone.

The Board set April 26, 2023 as the record date for the Annual Meeting. Holders of common stock at the close of business on the record date are entitled to vote their shares at the Annual Meeting, and any further postponements or adjournments of the Annual Meeting.

There were [5,200,729] shares of our common stock issued and outstanding as of the record date, all of which are entitled to be voted at the Annual Meeting. See “-What are the voting rights of Eterna stockholders?”

In accordance with the SEC rules, we may furnish proxy materials, including this Proxy Statement and our 2022 Annual Report, to our stockholders by providing access to such documents on the Internet instead of mailing printed copies. Accordingly, we are sending the Notice to our stockholders of record and beneficial stockholders as of April 26, 2023.

The Notice and proxy card or voting instruction form included with the proxy materials will contain instructions on how to view the proxy materials on the Internet. Electronic copies of this Proxy Statement and the 2022 Annual Report are available at www.proxyvote.com.

The Notice and proxy card or voting instruction form included with the proxy materials will contain instructions on how to request electronic delivery of future proxy materials. Choosing to receive your future proxy materials by email will eliminate the cost of printing and mailing documents and will reduce the associated environmental impact. If you choose to receive future proxy materials by email, you will receive an email next year with instructions containing a link to those materials and a link to the proxy voting site. Your election to receive proxy materials by email will remain in effect until you terminate it.

Holders of our common stock are entitled to one vote per share on each matter that is submitted to stockholders for approval.

You may change your vote or revoke your proxy at any time before the vote at the Annual Meeting. You may change your vote prior to the Annual Meeting by executing a valid proxy card bearing a later date and delivering it to us prior to the Annual Meeting at Eterna Therapeutics Inc., 1035 Cambridge Street, Suite 18A, Cambridge, MA 02141. Only your latest dated proxy we receive at or prior to the Annual Meeting will be counted. You may also revoke your proxy and change your vote at any time before the final vote at the Annual Meeting by voting again via the Internet or by telephone. Attendance at the virtual meeting will not by itself revoke a previously granted proxy. If you hold shares in street name and wish to change your vote, you must follow the directions provided by your brokerage or other financial intermediary.

The Board recommends that you vote:

When you properly submit your proxy, the shares it represents will be voted at the Annual Meeting in accordance with your directions. Unless otherwise specified in the proxy, shares of our stock represented by proxies will be voted:

The presence at the meeting, virtually or by proxy, of the holders of a majority of the shares of common stock entitled to vote at the meeting as of the record date will constitute a quorum, permitting the conduct of business at the Annual Meeting. If less than a majority of such shares of common stock is represented at the Annual Meeting, the chairman of the meeting may adjourn the Annual Meeting to another date, time or place. Notice need not be given of the new date, time or place if announced at the Annual Meeting before an adjournment is taken, unless (i) the date of any adjourned meeting is more than 30 days after the date for which the meeting was originally noticed or (ii) the Board fixes a new record date for the Annual Meeting, in which cases notice of the place, if any, date, and time of the adjourned meeting and the means of remote communications, if any, by which stockholders and proxy holders may be deemed to be present in person and vote at such adjourned meeting, shall be given in conformity with our Bylaws.

Technicians will be available to assist you if you experience technical difficulties accessing the virtual meeting website. If you encounter any difficulties accessing the virtual meeting during the check-in or meeting time, please call the technical support number that will be posted on the virtual shareholder meeting log-in page.

Under our Bylaws, if a quorum is present, the director nominees will be elected by a plurality of the votes cast. Accordingly, the nominees who receive the largest number of votes cast in favor of their election will be elected.

Stockholders entitled to vote may vote in favor of all of the nominees or any individual nominee or withhold their votes as to all the nominees or any individual nominee.

If a quorum is present, ratification of the appointment of our independent registered public accounting firm requires that a majority of the votes cast at the Annual Meeting are cast “FOR” ratification.

If a quorum is present, approval requires that a majority of the votes cast at the Annual Meeting are cast “FOR” approval.

If a quorum is present, approval requires that a majority of the votes cast at the Annual Meeting are cast “FOR” approval.

Proxies received but marked “ABSTAIN” will be included in the calculation of the number of shares considered to be present at the meeting for purposes of determining a quorum, but abstentions will not have an effect on the outcome of any proposal.

Broker non-votes occur when a broker, bank, or other nominee holds shares in “street name” for a beneficial owner and that nominee does not vote the shares because it (i) has not received voting instructions from the beneficial owner and (ii) lacks discretionary voting power to vote those shares with respect to a particular proposal. Broker non-votes are counted for purposes of determining the existence of a quorum at the Annual Meeting, but they will have no effect on the outcome of any proposal on which we receive a broker non-vote.

A broker is entitled to vote shares held for a beneficial owner on “routine” matters without instructions from the beneficial owner of those shares, which include the proposal to ratify Grant Thornton as our independent public accounting firm for the 2023 fiscal year (Proposal No. 2). On the other hand, absent instructions from the beneficial owner of such shares, a broker is not entitled to vote shares held for a beneficial owner on “non-routine” matters, which include Proposals Nos. 1, 3 and 4 described in this Proxy Statement.

If you hold your shares in street name, it is critical that you provide your broker, bank, or other nominee with instructions on how to cast your vote if you want it to count in the election of directors (Proposal No. 1), the approval, for purposes of complying with Nasdaq Listing Rule 5635(d), of the potential issuance and sale of more than 20% of our issued and outstanding common stock pursuant to the Lincoln Park Purchase Agreement (Proposal No. 3) and the approval of the Restated Plan Amendment (Proposal No. 4), each as described in this Proxy Statement. If you hold your shares in street name, and you do not instruct your broker, bank, or other nominee how to vote, then it will not be voted for the election of directors or with respect to the non-binding advisory resolutions.

If any other routine matters are properly brought before the Annual Meeting in addition to Proposal No. 2, then brokers holding shares in street name may vote those shares in their discretion for any such routine matters.

The U.S. Securities and Exchange Commission (the “SEC”) rules permit companies and intermediaries (e.g., brokers) to satisfy the delivery requirements for proxy statements and annual reports with respect to two or more stockholders sharing the same address by delivering only one (1) copy of our annual report and this Proxy Statement or the Notice addressed to those stockholders, if consented to by the stockholders. This delivery method, called “householding,” reduces our printing and mailing costs and provides extra convenience for stockholders. Stockholders who participate in householding and who request to receive printed proxy materials will continue to receive separate proxy cards.

Once a stockholder has received notification from its broker that it will be “householding” communications to such stockholder’s address, “householding” will continue until such stockholder is notified otherwise or until such stockholder notifies its broker or us that it no longer wishes to participate in “householding.” A stockholder may revoke such stockholder’s consent by notifying its broker or delivering written notice of such revocation to the Company at Eterna Therapeutics Inc., Attention: Secretary, Eterna Therapeutics Inc., 1035 Cambridge Street, Suite 18A, Cambridge, Massachusetts 02141. Upon written or oral request of a stockholder at a shared address to which a single copy of this Proxy Statement and 2022 Annual Report or Notice was delivered, we will deliver promptly separate copies of these documents or do so in the future if requested.

Pursuant to Rule 14a-8 under the Securities Exchange Act of 1934, as amended (the “Exchange Act”), our stockholders may present proper proposals for inclusion in our proxy statement and form of proxy and for consideration at the next annual meeting by submitting their proposals to us in a timely manner. Any stockholder of the Company who wishes to present a proposal for inclusion in the proxy statement and form of proxy for action at the 2024 annual meeting of stockholders (the “2024 Annual Meeting”) must comply with our Bylaws and the rules and regulations of the SEC, each as then in effect. Such proposals must be mailed to us at our offices at Eterna Therapeutics Inc., Attention: Secretary, 10355 Cambridge Street, Suite 18A, Cambridge, MA 02141. Under the rules of the SEC, any stockholder proposal intended to be presented at the 2024 Annual Meeting must be received no later

than January 3, 2024 in order to be considered for inclusion in our proxy statement and form of proxy relating to such meeting. Under the rules of the SEC, in the event we change the date of our 2024 Annual Meeting by more than thirty days from the one-year anniversary of the Annual Meeting, the deadline for a stockholder proposal to be included in our proxy statement and form of proxy relating to our 2024 Annual Meeting is a reasonable time before we begin to print and send our proxy materials for such meeting. Under our Bylaws, a stockholder must follow certain procedures to nominate persons for election as directors or to introduce an item of business at an annual meeting of stockholders. In order to be timely, we must receive notice of your intention to introduce a nomination or propose an item of business at our 2024 Annual Meeting between the close of business on January 3, 2024 and close of business on February 2, 2024. If we change the date of our 2024 Annual Meeting by more than thirty days before, or more than thirty days after, the one-year anniversary of the Annual Meeting, then the written notice of a stockholder proposal that is not intended to be included in our proxy statement must be delivered, or mailed and received, not later than the ninetieth day prior to our 2024 Annual Meeting or, if later, the tenth day following the day on which public announcement of the date of such meeting is first made. You are advised to review our Bylaws, which contain additional requirements with respect to advance notice of shareholder proposals and director nominees

In addition, for stockholder nominees for directors to be considered timely for inclusion on a universal proxy card pursuant to Rule 14a-19 under the Exchange Act, stockholders must provide notice to us no later than April 17, 2024, containing the information required by Rule 14a-19 under the Exchange Act.

If a stockholder notifies us of an intent to present a proposal at the 2024 Annual Meeting at any time after March 18, 2024 (and for any reason the proposal is voted on at that meeting), it will be considered untimely and our proxy holders will have the right to exercise discretionary voting authority with respect to the proposal, if presented at the meeting, without including information regarding the proposal in our proxy materials. Under the rules of the SEC, in the event we change the date of our 2024 Annual Meeting by more than thirty days after the one-year anniversary of the Annual Meeting, the deadline for a stockholder to submit a proposal for the 2024 Annual Meeting is a reasonable time before we begin to print and send our proxy materials.

Prior to the Annual Meeting, we will select an inspector of election for the meeting. Such inspector will determine the number of shares of common stock represented at the meeting, the existence of a quorum and the validity and effect of proxies, and shall receive, count and tabulate ballots and votes and determine the results thereof.

The Company is making this solicitation. We pay the cost of soliciting your proxy, and we reimburse brokerage firms and others for forwarding proxy materials to you. Our directors, officers and employees may participate in the solicitation of proxies without additional consideration. We may engage the services of a professional proxy solicitation firm to aid in the solicitation of proxies from certain brokers, bank nominees, and other institutional owners. Our costs for such services, if retained, will not be significant.

In accordance with Delaware law, a list of stockholders entitled to vote at the Meeting will be available at our executive office in Cambridge, Massachusetts on June 6, 2023, and will be accessible for ten days prior to the Meeting between the hours of 9:00 a.m. and 5:00 p.m. The list of stockholders will also be available electronically at the Meeting.

Pursuant to the authority granted to our Board under Article III of our Bylaws, the Board shall determine the number of directors constituting the entire Board by duly adopted resolutions of the Board, and the Board has fixed such number at five. All five directors are to be elected at the Annual Meeting, each to hold office until the 2024 Annual Meeting of stockholders or until his successor is duly elected and qualified. Each stockholder of record on April 26, 2023 is entitled to cast one vote for each share of our common stock either in favor of or against the election of each nominee, or to abstain from voting on any or all nominees. Although management does not anticipate that any nominee will be unable or unwilling to serve as a director, in the event of such an occurrence, proxies may be voted in the discretion of the persons named in the proxy for a substitute designated by the Board, unless the Board decides to reduce the number of directors constituting the Board. Our directors are elected by a plurality of vote cast; therefore, the nominees who receive the largest number of votes cast in favor of their election will be elected.

The names of our directors nominees and executive officers and their respective ages, positions, biographies and, in the case of directors, their qualifications to serve as directors, are set forth below.

Our common stock is listed on the Nasdaq Capital Market under the symbol “ERNA.” Pursuant to our Bylaws and the Delaware General Corporation Law, our business and affairs are managed under the direction of our Board. Directors are kept informed of the Company’s business through discussions with management, by reviewing materials provided to them and by participating in meetings of the Board and its committees.

The Board has adopted Corporate Governance Guidelines that contain general principles regarding the responsibilities and function of our Board and Board Committees, a copy of which is available at: www.eternatx.com under Investor Relations—Governance. Information contained on, or accessible through, our website does not form a part of this Proxy Statement and is not incorporated by reference.

The Board believes it is appropriate to separate the roles of the Chairman of the Board and the Chief Executive Officer. The Chairman of the Board is charged with acting as a liaison between the Board and our management team, including oversight of management’s implementation of the Board’s strategies and directives. The Chief Executive Officer is responsible for providing general supervision of the affairs of the Company and general control of all of our business subject to the ultimate authority of the Board.

Risk Oversight. One of the key functions of our Board is informed oversight of our risk management process. Our Board administers this oversight function directly through our Board as a whole, as well as through various standing committees of our Board that address risks inherent in their respective areas of oversight. In particular, our Board is responsible for monitoring and assessing strategic risk exposure, and 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. The Audit Committee also has the responsibility to review with management the process by which risk assessment and management is undertaken, monitor compliance with legal and regulatory requirements, and review the adequacy and effectiveness of our internal controls over financial reporting. Our Nominating and Corporate Governance Committee is responsible for periodically evaluating our company’s corporate governance policies and systems.

Diversity and Inclusion. Although we do not have a formal diversity policy, the Nominating and Corporate Governance Committee, in accordance with its policies and procedures for director candidates, seeks to identify candidates who will enhance the Board’s overall diversity.

Corporate Governance Guidelines. Our Board strongly supports effective corporate governance and has developed and followed a program of strong corporate governance. Our Nominating and Corporate Governance Committee is responsible for overseeing our governance guidelines and reporting and making recommendations to the Board concerning corporate governance matters. Our guidelines are published on our website at www.eternatx.com and are available in print to any stockholder who requests them from our Secretary.

Director Independence. Our Board undertook a review of the independence of each director. Based on information provided by each director concerning his background, employment, and affiliations, our Board has determined that the Board meets independence standards under the applicable rules and regulations of the SEC and the listing standards of Nasdaq. The Board of Directors has affirmatively determined that the following Directors are “independent” as defined in the listing standards of Nasdaq: Charles Cherington; Nicholas J. Singer; and William Wexler. In making these determinations, our Board considered the current and prior relationships that each non-employee director has with our Company and all other facts and circumstances our Board deemed relevant in determining their independence, including the beneficial ownership of our capital stock by each non-employee director, and the transactions involving them described in the section titled “Certain Relationships and Related Party Transactions.”

Code of Ethics. Our Board has adopted a Code of Conduct and Ethics that applies to all of our employees, officers and directors, including our Chief Executive Officer, Chief Financial Officer and other executive and senior financial officers. The full text of our Code of Conduct and Ethics is available on our website at www.eternatx.com under Investor Relations—Governance and is available in print to any stockholder who requests a copy from our Secretary. We intend to disclose future amendments to certain provisions of our Code of Business Conduct and Ethics, or waivers of certain provisions as they relate to our directors and executive officers, at the same location on our website or in our public filings. The information on our website is not intended to form a part of or be incorporated by reference into this Proxy Statement.

Board and Committee Meetings; Meeting Attendance. The Board and its Committees meet regularly during the year, and they hold special meetings and act by unanimous written consent as circumstances require. Independent directors meet at regularly scheduled executive sessions without management present. Our Board held 28 meetings in calendar year 2022. Each director attended at least 75 percent of the aggregate of the total number of Board meetings and the total number of meetings held by all committees of the Board on which he or she served.

Although we do not have a formal policy with respect to the attendance of directors at our annual stockholder meetings, we encourage all of our directors to attend our annual stockholder meetings.

Board Committees. Our Board has three standing committees: an Audit Committee; a Compensation Committee; and a Nominating and Corporate Governance Committee. Each of the committees reports to the Board as it deems appropriate and as the Board may request. The composition, duties and responsibilities of these committees are set forth below. In the future, our Board may establish other committees, as it deems appropriate, to assist it with its responsibilities.

The table below provides current committee membership information:

Committee Meetings. During 2022, our Audit Committee held 11 meetings and took action by written consent two times; our Compensation Committee held six meetings and took action by written consent eight times; and our Nominating and Corporate Governance Committee held one.

Audit Committee. We have a standing audit committee established in accordance with Section 3(a)(58)(A) of the Exchange Act. Our Audit Committee is responsible for, among other things:

Our Audit Committee consists of William Wexler (Chair), Charles Cherington and Nicholas J. Singer, all of whom meet the requirements for independence of Audit Committee members under applicable Nasdaq and SEC rules, including Rule 10A-3 promulgated under the Exchange Act. All of the members of our Audit Committee meet the requirements for financial literacy under the applicable rules and regulations of the SEC and Nasdaq. In addition, Mr. Singer qualifies as our “Audit Committee financial expert,” as such term is defined in Item 407 of Regulation S-K.

Our Board has adopted a written charter for the Audit Committee, which is available on our website at: www.eternatx.com under Investor Relations—Governance. The information on our website is not intended to form a part of or be incorporated by reference into this Proxy Statement.

Compensation Committee. Our Compensation Committee is responsible for, among other things:

Our Compensation Committee consists of Nicholas J. Singer, Charles Cherington and William Wexler, with Mr. Singer serving as the chair. Each member of our Compensation Committee is independent, as defined under the Nasdaq listing rules, including Nasdaq’s additional independence standards for Compensation Committee members. Each member of our Compensation Committee is a non-employee director (within the meaning of Rule 16b-3 under the Exchange Act).

The Compensation Committee may establish and delegate authority to one or more subcommittees consisting of one or more of its members, when the Compensation Committee deems it appropriate to do so in order to carry out its responsibilities. In carrying out its responsibilities, the Compensation Committee shall be entitled to rely upon the advice and information that it receives in its discussions and communications with management and such experts, advisors and professionals with whom the Compensation Committee may consult.

Our Board has adopted a written charter for the Compensation Committee, which is available on our website at: www.eternatx.com under Investor Relations—Governance. The information on our website is not intended to form a part of or be incorporated by reference into this Proxy Statement.

Nominating and Corporate Governance Committee. Our Nominating and Corporate Governance Committee is responsible for, among other things:

Our Nominating and Corporate Governance Committee consists of Charles Cherington, Nicholas J. Singer and William Wexler, with Mr. Cherington serving as the chair. Each member of our Nominating and Corporate Governance Committee is independent as defined under the Nasdaq listing rules.

Our Board has adopted a written charter for the Nominating and Corporate Governance Committee, which is available on our website at: www.eternatx.com under Governance. The information on our website is not intended to form a part of or be incorporated by reference into this Proxy Statement.

Director Nominations. The Nominating and Corporate Governance Committee may solicit recommendations for the Board from any or all of the following sources: non-management directors, the Chief Executive Officer, other executive officers, third-party search firms, or any other source it deems appropriate, including stockholders. The Committee will evaluate all such proposed director candidates in the same manner, with no regard to the source of the initial recommendation of such proposed director candidate. In identifying and evaluating proposed director candidates, the Nominating and Corporate Governance Committee considers, in addition to the minimum qualifications and other criteria for Board membership, all facts and circumstances that it deems appropriate or advisable, including, among other things:

The Nominating and Corporate Governance Committee will consider candidates recommended by the Company’s stockholders holding at least three (3%) of the Company’s common stock continuously for at least twenty four (24) months prior to the date of the submission of the recommendation in the same manner as candidates recommended from other sources.

Although we have not adopted a formal policy regarding the consideration of Board candidates recommended by our stockholders, the Board believes that the procedures set forth in our Bylaws are currently sufficient and that the establishment of a formal policy is not necessary. Without limiting the requirements contained in our Bylaws, the recommendation must set forth (i) as to each person whom the stockholder proposes to nominate for election as a director (A) the name, age, business address and residence address of the person, (B) the principal occupation or employment of the person, (C) the class and number of shares of capital stock of the Company that are owned beneficially or of record by the person, (D) a description of all arrangements or understandings between the stockholder and each nominee and any other person or persons (naming such person or persons) and (E) any other information relating to the person that would be required to be disclosed in a proxy statement or other filings required to be made in connection with solicitations of proxies for election of directors pursuant to Section 14 of the Exchange Act and the rules and regulations promulgated thereunder; and (ii) as to the stockholder giving the notice (A) the name and record address of such stockholder as they appear on the Company’s books, (B) the class and number of shares of capital stock of the Company that are owned beneficially and of record by such stockholder and the beneficial owner, if any, on whose behalf the nomination is made and (C) any material interest of the stockholder in such nomination. Such notice must be accompanied by a written consent of each proposed nominee to being named as a nominee and to serve as a director if elected.

While we do not have a formal diversity policy with respect to Board composition, the Board believes it is important for the Board to have diversity of knowledge base, professional experience and skills, and the Corporate Governance and Nominating Committee takes these qualities into account when considering director nominees for recommendation to the Board. We believe diversity of perspectives and experience enhances our effectiveness. Given our commitment to diversity and related considerations in our appointment, hiring, and promotion practices, we have not adopted a formal diversity policy or specific diversity targets for determining Board membership or executive appointments. However, the Board remains committed to monitoring best practices and corporate governance developments in this area.

Director Election - Plurality Vote. Director nominees are elected by our stockholders based on a plurality of the votes of shares present and entitled to vote. Accordingly, the nominees who receive the largest number of votes cast will be elected.

Management Succession. As reflected in our Nominating and Corporate Governance Committee Charter, one of the Board’s primary responsibilities includes planning for CEO succession and monitoring and advising on management’s succession planning for other key officers of the Company, with the goal of establishing an effective succession plan. Our Nominating and Corporate Governance Committee and the Board have not yet established a formal succession plan for our CEO, but the Board routinely discusses management succession during the course of its meetings, including during sessions held by the Company’s non-management directors and our Nominating and Corporate Governance Committee has identified individuals who would be able to undertake the CEO’s duties on an interim basis if necessary.

All interested parties, including stockholders, may communicate with the Company or our Board by letter addressed to Eterna Therapeutics Inc., Attention: Secretary, 1035 Cambridge Street, Suite 18A, Cambridge, Massachusetts 02141, or by e-mail to Andrew.Jackson@eternatx.com or Sandra.Gurrola@eternatx.com.

Certain Relationships and Related Party Transactions

Except as set forth below, since January 1, 2022, there has not been nor are there currently proposed any transactions or series of similar transactions to which we were or are to be a party in which the amount involved exceeds the lesser of $120,000 or one percent (1%) of the average of our total assets at year-end for the last two completed fiscal years and in which any director, executive officer, holder of more than 5% of the common stock or any member of the immediate family of any of the foregoing persons had or will have a direct or indirect material interest.

As previously reported, we paid consideration totaling approximately $124.0 million in respect of our acquisition of Novellus, Inc., which we refer to as the “Novellus Acquisition,” consisting of (a) $22.8 million in cash and (b) approximately 351,000 shares of our common stock, which under the terms of the agreement and plan of acquisition, dated as of July 16, 2021, by and between us, Novellus and the other parties thereto (the “Novellus Acquisition Agreement”), were valued at a total of $102.0 million, based on a price of 290.51 per share of our common stock. In connection with the Novellus Acquisition, (i) Factor Bioscience, of which Dr. Angel beneficially owns approximately 64% of its outstanding equity, received approximately $1.7 million in cash consideration from us and approximately 129,000 shares of common stock, and (ii) Dr. Angel received approximately $2.0 million in cash consideration from us and approximately 31,000 shares of common stock. In addition, Dr. Angel also received approximately 14,000 shares of common stock, which we had placed in escrow for a period that ended on July 16, 2022 to secure indemnification obligations to us under the Novellus Acquisition Agreement. As part of the Novellus Acquisition, we also acquired 25.0% of the total outstanding equity interests of NoveCite, Inc. (“NoveCite”), a corporation focused on developing an allogeneic mesenchymal stem cell product for patients with acute respiratory distress syndrome. In October 2020, Novellus Limited (as sublicensor) and NoveCite (as sublicensee) entered into an exclusive license agreement (the “NoveCite Agreement”) to license a novel cellular therapy for acute respiratory indications, which Novellus Limited was licensing from Factor Limited under the Novellus-Factor License Agreement.

In November 2020, Novellus Limited, our wholly owned subsidiary following the Novellus Acquisition, and Factor Bioscience Limited, a subsidiary of Factor Bioscience (“Factor Limited”), entered into the Third Amended and Restated Exclusive License Agreement (the “Novellus-Factor License Agreement”), pursuant to which Factor Limited granted to Novellus Limited an exclusive license under certain patents owned by Factor Limited for the development of certain stem cell-based cellular therapies for treating diseases and conditions in humans and animals.

In December 2020, Eterna LLC, our wholly owned subsidiary, entered into option agreements (the “Novellus-Factor Option Agreements”) with Novellus Limited. and Factor Limited (together, the “Licensors”) to obtain the right to exclusively license the Licensors’ intellectual property and mRNA cell reprogramming and gene editing technology for use in the development of certain cell-based therapies to be evaluated and developed for treating human diseases, including certain types of cancer, sickle cell disease, and beta thalassemia (the “Licensed Technology”).

In April 2021, Eterna LLC and the Licensors entered into an exclusive license agreement (the “Original Factor License Agreement”) pursuant to which Eterna LLC acquired an exclusive worldwide license to the Licensed Technology for use in the development of certain mRNA, gene-editing, and cellular therapies to be evaluated and developed for treating human diseases, including certain types of cancer, sickle cell disease, and beta thalassemia.

As a result of the July 2021 Novellus Acquisition, the rights and obligations of Novellus Limited under the Novellus-Factor License Agreement pertaining to any and all licensed products from Factor Limited inured to Eterna. Our agreement with Factor Limited under the Original Factor License Agreement remained unchanged after the completion of the Novellus Acquisition.

In November 2022, following the expiration of one of the delineated milestone deadlines for certain regulatory filings required under the Novellus-Factor License Agreement expired, which permitted Factor Limited to terminate the license granted to Novellus Limited thereunder, we entered into the first amendment to the Original Factor License Agreement (the “Amended Factor License Agreement”), pursuant to which, among other things, Factor Limited granted to Eterna LLC an exclusive, sublicensable license under certain patents owned by Factor Limited (the “Factor Patents”) for the purpose of identifying and pursuing certain opportunities to grant to third parties sublicenses to the Factor Patents. The Amended Factor License Agreement also (i) terminated the Novellus-Factor License Agreement, (ii) confirmed Factor Limited’s grant to Eterna LLC of the rights and licenses Novellus Limited previously granted to Eterna LLC under the Novellus-Factor License Agreement on the same terms and conditions as granted by Novellus Limited to Eterna LLC under such agreement, (iii) confirmed that the sublicense granted by Novellus Limited in accordance with the Novellus-Factor License Agreement to NoveCite (as discussed below),

survived termination of the Novellus-Factor License Agreement; and (iv) removed Novellus Limited from the Amended Factor License Agreement and the NoveCite Agreement and replaced Novellus Limited with Factor Limited as the direct licensor to Eterna LLC and NoveCite under such agreements, respectively.

On February 20, 2023, we and Factor Limited entered into an exclusive license agreement (the “Exclusive Factor License Agreement”), which terminated and replaced in its entirety the Amended Factor License Agreement. Subject to certain exclusive licenses or other rights granted by Factor Limited to certain third parties as of the effective date of the Amended Factor License Agreement, Factor granted us the exclusive, sublicensable license under the Factor Patents.

The term of the Exclusive Factor License Agreement expires on November 22, 2027 (the “Expiration Date”) but will be automatically extended for an additional two and a half years (such period, the “Renewal Term”) if we receive at least $100 million in fees from sublicenses to the Factor Patents (“Sublicense Fees”) granted by it pursuant to the Exclusive Factor License Agreement. Pursuant to the Exclusive Factor License Agreement, we will pay to Factor 20% of any Sublicense Fee received by us before the Expiration Date and 30% of any Sublicense Fees received by us during the Renewal Term. We may terminate the Exclusive Factor License Agreement upon 120 days’ written notice to Factor, and both parties otherwise have additional customary termination rights, including in connection with certain uncured material breaches of the Exclusive Factor License Agreement and specified bankruptcy events. Under the Exclusive Factor License Agreement, we are obligated to pay the expenses incurred by Factor Limited in preparing, filing, prosecuting and maintaining the Factor Patents and agreed to bear all costs and expenses associated with enforcing and defending the Factor Patents in any action or proceeding arising from pursuit of sublicensing opportunities under the license granted under the Exclusive Factor License Agreement.

Pursuant to the MSA we entered into with Factor Bioscience and the related Work Order No. 1 (the “WO1”), Factor Bioscience is providing us with certain mRNA cell engineering research support services, including (i) access to Factor Bioscience’s research laboratory facilities located in Cambridge, Massachusetts, (ii) access to Factor Bioscience’s scientific equipment, (iii) training of our research staff in mRNA, iPSC, and gene editing technology, (iv) copies of protocols, formulations, and sequences useful for the development of mRNA cell engineering products and (v) in vitro transcription templates, mRNA constructs, and iPS cells useful for the development of mRNA cell engineering products. In consideration for entry into the MSA, we agreed to pay Factor Bioscience an initial fee of $5.0 million, payable in twelve equal monthly installments of approximately $0.4 million, and, following the initial 12-month period, a monthly fee of $0.4 million until such time as the WO1 is terminated. We may terminate the work under the WO1 on or after the second anniversary of the date of the MSA, subject to providing Factor Bioscience with 120 days’ prior notice. Factor Bioscience may terminate such work order only on and after the fourth anniversary of the date of the MSA, subject to providing us with 120 days’ prior notice.

On October 8, 2022, we entered into the Exacis Option Agreement with Exacis, pursuant to which Exacis granted us the option to negotiate and enter into an exclusive worldwide license to certain of the technology licensed by Exacis for the treatment of cancer in humans. The Exacis Option Agreement provided for us paying Exacis a fee of $250,000 for the option, which would be creditable against the fees or purchase price payable under any such license if entered into by us in accordance with Exacis Option Agreement. We did not exercise the option, and the Exacis Option Agreement terminated on December 31, 2022.

On November 23, 2022, we entered into a securities purchase agreement with certain investors (the “Q4-22 PIPE Investors”), providing for the private placement (the “Q4-22 PIPE Transaction”) to the Q4-22 Investors of approximately 2,185,000 units, each unit consisting of (i) one share of common stock and (ii) two warrants, each exercisable to purchase one share of common stock at an exercise price of $3.28 per share (the “Q4-22 Warrants”), at a purchase price of $3.53 per unit (inclusive of $0.125 per Q4-22 Warrant), for net proceeds of approximately $7.4 million. The Company received aggregate gross proceeds of approximately $7.7 million, and the Q4-22 PIPE Transaction closed on December 2, 2022. Each Q4-22 Warrant becomes exercisable six months following the date of closing, expires five-and-one-half years following such date, and is subject to customary adjustments.

Mr. Charles Cherington, Chairman of the Company’s Board of Directors, and Mr. Nicholas Singer, a director of the Company, participated in the Q4-22 PIPE Transaction on the same terms and subject to the same conditions as all other Q4-22 PIPE Investors.

Our Audit Committee is responsible for the review, approval, or ratification of any potential conflict of interest transaction involving any of our directors or executive officers, director nominees, any person known by us to be the beneficial owner of more than 5% of our outstanding capital stock, or any family member of or related party to such persons, including any transaction required to be reported under Item 404(a) of Regulation S-K promulgated by the SEC.

In reviewing any such proposed transaction, our Audit Committee is tasked with considering all relevant facts and circumstances, including the commercial reasonableness of the terms, the benefit or perceived benefit, or lack thereof, to us, opportunity costs of alternate transactions, the materiality and character of the related person’s direct or indirect interest and the actual or apparent conflict of interest of the related person.

Under our policy, employees are required to report any material transaction or relationship that could result in a conflict of interest to our compliance officer.

The following table sets forth information known to us regarding beneficial ownership of common stock as of March 20, 2023 by:

Beneficial ownership is determined according to the rules of the SEC, which generally provide that a person has beneficial ownership of a security if he, she or it possesses sole or shared voting or investment power over that security, including options and warrants that are currently exercisable or exercisable within 60 days. In computing the number of shares beneficially owned by a person or entity and the percentage ownership of that person or entity in the table below, all shares subject to options, warrants and restricted stock units held by such person or entity were deemed outstanding if such securities are currently exercisable, or exercisable or would vest based on service-based vesting conditions within 60 days of March 20, 2023, assuming that the liquidity event vesting conditions had been satisfied as of such date. These shares were not deemed outstanding, however, for the purpose of computing the percentage ownership of any other person or entity.

The beneficial ownership of our common stock is based on 5,200,729 shares of our common stock outstanding as of April 17, 2023.

Unless otherwise indicated, we believe that each person named in the table below has sole voting and investment power with respect to all shares of common stock beneficially owned by him.

Unless otherwise noted, the business address of each of these shareholders is c/o Eterna Therapeutics, Inc., 1035 Cambridge Street, Suite 18A, Cambridge, MA 02141.

Section 16(a) of the Exchange Act requires our directors, executive officers and persons who beneficially own more than 10% of a registered class of our equity securities to file with the SEC reports of ownership of, and transactions in, our equity securities. To our knowledge, based solely on a review of copies of such reports that we received, our records and written representations received from our directors, executive officers and certain of those persons who own greater than 10% of any class of our equity securities, for the year ended December 31, 2022, all applicable Section 16(a) filing requirements were complied with on a timely basis.

The following table contains information as of December 31, 2022 with respect to compensation plans under which any of our equity securities are authorized for issuance.

When determining executive officer compensation, and the various components that comprise it, our Compensation Committee evaluates and considers publicly available executive officer compensation survey data to present a competitive compensation package to attract and retain top talent, including an appropriate level of salary, performance-based bonus and equity incentives. Typically, the Compensation Committee evaluates between three and five different sources of compensation data to provide relevant market benchmark data for a given executive role. Additionally, the Compensation Committee is authorized to engage outside advisors and experts to assist and advise the Compensation Committee on matters relating to executive compensation. The Compensation Committee currently retains the services of Aon’s Human Capital Solutions practice, a division of Aon plc (“Aon”), an independent compensation consultant. Our Chief Executive Officer presents compensation recommendations to the Compensation Committee with respect to the executive officers other than himself. The Compensation Committee considers such recommendations, in conjunction with input from the Compensation Committee’s independent compensation consultant, in making compensation decisions or recommendations to the full Board. The full board of directors participates in evaluating the performance of our executive officers, except that neither our former CEO, Howard J. Federoff, or our current CEO, Dr. Matthew Angel, participated when the Board evaluated their respective performance, and neither was present during voting or deliberations regarding their respective performance or compensation matters.

Under applicable SEC rules and regulations, all individuals who served as our principal executive officer during 2022, our two most highly compensated executive officers (other than our principal executive officer) who were serving as executive officers at December 31, 2022, and up to two additional individuals who would have been one of our top two most highly compensated executive officer had they been serving as an executive officer at the end of 2022 are referred to as our “named executive officers” and identified in the table below:

The following table sets out the compensation for our Named Executive Officers for the years ended December 31, 2022 and December 31, 2021:

The following is a discussion of each component of our executive compensation program for 2022.

Each of our named executive officers receives a base salary. The base salary is the fixed cash compensation component of our executive compensation program and it recognizes individual performance, time in role, scope of responsibility, leadership skills and experience. The base salary compensates an executive for performing his or her job responsibilities on a day-to-day basis. Generally, base salaries are reviewed annually company-wide and adjusted (upward or downward) when appropriate based upon individual performance, expanded duties, changes in the competitive marketplace and, with respect to upward adjustments, if we are, financially and otherwise, able to pay it.

We try to offer competitive base salaries to help attract and retain executive talent.

In addition to base salaries, our Compensation Committee has the authority to award discretionary annual bonuses to our named executive officers based on corporate and individual performance. Incentives, as a percent of salary, increase with executive rank so that, as rank increases, a greater portion of total annual cash compensation is based on annual corporate and individual performance.

Annual incentives are awarded based on quantitative performance standards and reward performance of each named executive officer individually. The determination of a named executive officer’s performance may vary from year to year depending on economic conditions and conditions in the industry in which we operate and may be based on measures such as revenue, achievement of certain research and development milestones, completion of a strategic transaction, and other metrics the directors and management believe to provide proper incentives for achieving long-term shareholder value for Eterna. The Board retains full discretion over performance evaluation and the amount of any bonuses to be paid to a named executive officer.

At our 2021 annual meeting of stockholders, our stockholders approved a restatement of the Eterna Therapeutics Inc. Restated 2020 Stock Incentive Plan (the “Restated Plan”). The general purpose of the Restated Plan is to provide a means whereby eligible employees, officers, employee and non-employee directors, consultants and prospective employees may develop a sense of proprietorship and personal involvement in our development and financial success, and to encourage them to devote their best efforts to us, thereby advancing our interests and the interests of stockholders. The Board believes that the granting of stock options, restricted stock, restricted stock units, performance awards, unrestricted stock awards and similar kinds of equity-based compensation promotes continuity of management and increases incentive and personal interest in our welfare by those who are primarily responsible for shaping and carrying out our long-range plans and securing growth and financial success. In general, the Restated Plan is administered by the Compensation Committee. The Compensation Committee determines the persons to whom awards issuable under the Restated Plan may be granted. The Compensation Committee may also establish rules and regulations for the administration of the Restated Plan and amendments or modifications of outstanding awards. The Compensation Committee also delegates authority to certain executive officers grant awards and execute award agreements, subject to applicable law and the Restated Plan. Each award is set forth in a separate agreement with the person receiving the award and will indicate the type, terms and conditions of the award. A brief description of the material terms of the Restated Plan and the equity awards thereunder follows.

Persons eligible to receive awards under the Restated Plan consist of our employees, officers, directors, consultants, independent contractors who, in the opinion of the Compensation Committee, are in a position to contribute to our success, or any other person who is determined by the Compensation Committee to be a prospective employee, officer, director, consultant, advisor or other individual service provider, any entity whose financials statements are required to be consolidated with our company, and any other entity that the Compensation Committee determines to be an affiliate of our company. As of March 20, 2022, we had nine full-time employees, including three executive officers.

The aggregate number of shares of common stock initially available for issuance in connection with awards granted under the Restated Plan is equal to the sum of (a) approximately 424,000 shares and (b) an annual increase on January 1 of each year from 2022 through 2031 equal to the lesser of (i) 5% of the number of shares of common stock outstanding on the immediately preceding December 31 and (ii) such smaller number of shares of common stock as may be determined by the Board.

Incentive stock options, or ISOs, that are intended to meet the requirements of Section 422 of the Code may be granted under the Restated Plan with respect to all of the shares of common stock authorized for issuance under the Restated Plan.

If any option or stock appreciation right, or SAR, granted under the Restated Plan is terminated without having been exercised in full or if any award is forfeited, the number of shares of common stock as to which such option, SAR

or award was terminated or forfeited will be available for future grants under the Restated Plan. Awards settled in cash will not count against the number of shares available for issuance under the Restated Plan; however, if any award is cancelled forfeited or terminated in order to pay the exercise price of a stock option, purchase price or any taxes or tax withholdings on an award, such shares will not be available for future awards under the Restated Plan.

The number of shares authorized for issuance under the Restated Plan and the foregoing share limitations are subject to customary adjustments for stock splits, stock dividends or similar transactions effected after the effective time of the Restated Plan.

Options granted under the Restated Plan may be either ISOs or “nonstatutory stock options,” or NSOs, that do not meet the requirements of Section 422 of the Code. The Compensation Committee will determine the exercise price of options granted under the Restated Plan. The exercise price of options may not be less than the fair market value per share of common stock on the date of grant (or 110% of fair market value in the case of ISOs granted to a ten-percent stockholder).

If on the date of grant the common stock is listed on a stock exchange or is quoted on an automated quotation system, the fair market value will generally be the closing sale price on the last trading day before the date of grant. If no such prices are available, the fair market value will be determined in good faith by the Compensation Committee based on the reasonable application of a reasonable valuation method.

No option may be exercisable for more than ten years (five years in the case of an ISO granted to a ten-percent stockholder) from the date of grant. Options granted under the Restated 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.

Generally, the option price may be paid (a) in cash or by certified check, bank draft or money order, (b) through delivery of shares of common stock having a fair market value equal to the purchase price, or (c) any other methods of payment that the Compensation Committee permits in its sole and absolute discretion, including a cashless exercise program.

The Compensation Committee may grant SARs under the Restated Plan. The Compensation Committee will determine the other terms applicable to SARs. The exercise price per share of a SAR will not be less than 100% of the fair market value of a share of common stock on the date of grant, as determined by the Compensation Committee. The maximum term of any SAR granted under the Restated Plan is ten years from the date of grant. Generally, each SAR will entitle a participant upon exercise to an amount equal to:

Payment may be made in shares of common stock, in cash, or partly in common stock and partly in cash, all as determined by the Compensation Committee.

The Compensation Committee may award restricted common stock and/or restricted stock units under the Restated 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. Restricted stock units confer the right to receive shares of 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. The restrictions and conditions applicable to each award of restricted stock or restricted stock units may include performance-based conditions. Dividends with respect to restricted stock may be paid to the holder of the shares as and when dividends are paid to stockholders or at the time that the restricted stock vests, as determined by the Compensation Committee. Dividend equivalent amounts may be paid with respect to restricted stock units either when cash dividends are paid to stockholders or when the units vest. Unless the Compensation Committee determines otherwise, holders of restricted stock will have the right to vote the shares.

The Compensation Committee may award performance shares and/or performance units under the Restated Plan. Performance shares and performance units are awards, denominated in either shares or U.S. dollars, which are earned during a specified performance period subject to the attainment of performance criteria, 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.

The Compensation Committee may award other types of equity-based or cash-based awards under the Restated Plan, including the grant or offer for sale of shares of common stock that do not have vesting requirements and the right to receive one or more cash payments subject to satisfaction of such conditions as the Compensation Committee may impose.

No award option may be transferred other than by will or by the laws of descent and distribution, and during a recipient’s lifetime an option may be exercised only by the recipient. However, the Compensation Committee may permit the holder of an option, restricted stock or other award to transfer the option, restricted stock or other award to immediate family members.

On May 20, 2021, the Board also approved our 2021 Inducement Stock Incentive Plan (the “2021 Inducement Plan”). The 2021 Inducement Plan was adopted without stockholder approval pursuant to Section 711 of the Company Guide of the NYSE American LLC, the stock exchange on which our common stock was previously listed. The 2021 Inducement Plan provides for the grant of equity-based awards, including non-qualified stock options, performance shares, performance unis, restricted stock, restricted stock units, and stock appreciation rights, and its terms are substantially similar to the Restated Plan, including with respect to treatment of equity awards in the event of a “Change in Control” as defined under both Restated Plan and the 2021 Inducement Plan. The awards available for grant under the 2021 Inducement Plan are available only to new employees and cannot be issued pursuant to ISOs under Section 422 of the Code.

Named executive officers are eligible to participate in our employee benefit plans, including our medical, disability and life insurance plans, in each case, on the same basis as all of our other employees. The employee benefit plans are designed to assist in attracting and retaining skilled employees critical to our long-term success. We also maintain a 401(k) plan for the benefit of our eligible employees, including the named executive officers, as discussed below.

We maintain a retirement savings plan, or 401(k) plan, that provides eligible U.S. employees with an opportunity to save for retirement on a tax advantaged basis. Under the 401(k) Plan, eligible employees may defer up to 90% of their compensation subject to applicable annual contribution limits imposed by the Internal Revenue Code of 1986, as amended, or the Code and limits imposed by non-discrimination testing. Our employees’ pre-tax contributions are allocated to each participant’s individual account and participants are immediately and fully vested in their contributions. The 401(k) plan is intended to be qualified under Section 401(a) of the Code with the 401(k) plan’s related trust intended to be tax exempt under Section 501(a) of the Code. As a tax-qualified retirement plan, contributions to the 401(k) plan and earnings on those contributions are not taxable to the employees until distributed from the 401(k) plan. As of December 31, 2022, we had not contributed a match to the employees’ contribution. Beginning on January 1, 2023, we began matching employees’ contributions at a rate of 100% of the first 3% of the employee’s contribution and 50% of the next 2% of the employee’s contribution, for a maximum match of 4%.

We do not maintain any pension benefit or retirement plans other than the 401(k) Plan.

Eterna does not maintain any nonqualified deferred compensation plan We do not maintain any nonqualified deferred compensation plans.

The following descriptions summarize the principal terms of our employment agreements with our named executive officers as of December 31, 2022.

On May 24, 2022, the Board appointed Dr. Angel as our interim Chief Executive Officer and President, which appointment became effective on May 26, 2022. On June 6, 2023, Dr. Angel was appointed as a member of our Board. Dr. Angel did not receive a salary or other cash compensation during his tenure as interim Chief Executive Officer and President, and he does not receive compensation for services as a member of the Board.

On August 1, 2022, we granted Dr. Angel a time-based non-qualified stock option covering 124,350 shares of common stock, of which 5,181 shares vested immediately on the grant date and the remaining 119,169 shares vest in 46 substantially equal monthly installments thereafter (the “2022 Grant”).

On December 30, 2022, we entered into an offer letter with Dr. Angel (the “Offer Letter”) effective on January 1, 2023 with respect to terms of his employment as our Chief Executive Officer and President. The compensatory terms of the Offer Letter, including equity awards, were approved by the Compensation Committee. Dr. Angel’s hiring, and his Offer Letter, were approved by the Board. We have been working together with Dr. Angel to negotiate in good faith and execute and deliver a formal, written employment agreement containing such other terms and conditions as are mutually acceptable to Dr. Angel and us (the “Employment Agreement”) as contemplated by the Offer Letter.

Under the terms of the Offer Letter, we will pay Dr. Angel an annual base salary of $350,000, which amount is subject to annual review by the Board or the Compensation Committee and subject to adjustment to reflect market practices among our peers in the sole discretion of the Board or the Compensation Committee.

We also paid Dr. Angel a cash signing bonus of $210,959, which represents the salary Dr. Angel would have earned for the period during which he served as interim Chief Executive Officer had the Offer Letter been in effect as of May 26, 2022.

Dr. Angel will be eligible to receive a performance bonus (the “Performance Bonus”) equal to two percent of the gross proceeds that we actually receive pursuant to all licensing, option, collaboration, partnership, joint venture, settlement, other similar agreements that we entered into, or other actions, judgments, or orders that generate cash proceeds to us, that are originated, negotiated and/or entered into by us during Dr. Angel’s employment (commencing on May 26, 2022), subject to certain conditions to be set forth in the Employment Agreement, including that Dr. Angel has not voluntarily resigned other than for good reason or has been terminated for cause.

In accordance with the terms of the Offer Letter, on January 12, 2023, we granted to Dr. Angel a time-based incentive stock option covering 132,003 shares of common stock, of which 110,043 shares vested immediately on the grant date and the remaining 21,960 shares vest in 35 substantially equal monthly installments on the first day of each month thereafter (the “2023 Grant”).

For both the 2022 Grant and the 2023 Grant, vesting generally requires Dr. Angel’s continued employment through the relevant vesting date.

If Dr. Angel’s employment is terminated by us without Cause or by Dr. Angel for Good Reason (which shall have the meaning as mutually agreed in the Employment Agreement), the portion of the 2022 Grant, the 2023 Grant and any other grant subsequently issued that would have vested during the twelve months following the date of termination would immediately vest, and Dr. Angel will have twelve months following the date of termination to exercise any vested options. In addition, the Performance Bonus will remain a continuing obligation of ours to pay Dr. Angel so long as Dr. Angel has remained employed by us for two years following the applicable agreement/arrangement underlying the applicable Performance Bonus and so long as Dr. Angel does not voluntarily resign other than for Good Reason or for Cause.

Pursuant to the Offer Letter, Dr. Angel is eligible for (a) reimbursement of reasonable business expenses, (b) participation in our benefit plans and (c) paid vacation days in accordance with our policies, as in effect from time to time.

For information on related party transactions with Dr. Angel, see Certain Relationships and Related Party Transactions above.

We entered into an executive employment agreement, dated April 1, 2021 and effective as of April 16, 2021, with Howard J. Federoff with respect to terms of his employment as our Chief Executive Officer and President. The compensatory terms of the executive employment agreement, including equity awards, were approved by the Compensation Committee, which consists of two disinterested members of the Board. Dr. Federoff’s hiring, and his executive employment agreement, were approved by the Board.

The executive employment agreement provided for our at-will employment of Dr. Federoff as our Chief Executive Officer and President for a term commencing on April 16, 2021 and continuing until terminated by us or Dr. Federoff. Dr. Federoff resigned as the Company’s Chief Executive, which became effective on May 26, 2022.

Under the terms of the executive employment agreement, we paid Dr. Federoff an annual base salary of $450,000, which amount was subject to annual review by the Board or the Compensation Committee and subject to adjustment to reflect market practices among our peers in the sole discretion of the Board or the Compensation Committee. Dr. Federoff was also eligible to receive an annual cash bonus award in an amount up to 50% of his base salary upon achievement of reasonable performance targets set by the Board or the Compensation Committee, each in its sole discretion. The bonus would be determined by the Board or the Compensation Committee and paid annually in March in the year following the performance year on which such bonus was based. For the year ended December 31, 2021 we paid Dr. Federoff a $159,375 cash bonus. The agreement also provided for the grant of certain equity awards and severance benefits.

Effective May 26, 2022 (the “Separation Date”), Dr. Federoff resigned as an employee. Upon the effective date of his resignation, we entered into a Separation Agreement and General Release with Dr. Federoff (the “Separation Agreement”), pursuant to which Dr. Federoff resigned from his positions as Chief Executive Officer and as an officer, director and employee of the Company and all subsidiaries. In consideration for Dr. Federoff’s execution of the Separation Agreement and non-revocation of a waiver and release of claims relating thereto, Dr. Federoff was entitled to the following benefits under the Separation Agreement:

Under the Separation Agreement, Dr. Federoff agreed to cooperate with and assist us regarding certain matters and transitioning his employment duties and responsibilities. Subject to certain exceptions and limitations, the Separation Agreement included a general release of claims by Dr. Federoff in favor of us and certain related persons and parties, and customary confidentiality and mutual non-disparagement provisions. The Separation Agreement also included

certain other customary representations, warranties and covenants of Dr. Federoff, and provided for reimbursement of certain expenses incurred by Dr Federoff. The Separation Agreement superseded all other agreements or arrangements between Dr. Federoff and us regarding the subject matter of the agreement, including those with respect to severance payments and benefits.

We entered into an amended and restated employment agreement, dated as of May 10, 2022, with Andrew Jackson with respect to his employment as our Chief Financial Officer. The employment agreement provides for our at-will employment of Mr. Jackson as our Chief Financial Officer for a term commencing on May 31, 2022 and continuing until terminated by us or Mr. Jackson.

Under the terms of the employment agreement, we will pay Mr. Jackson an annual base salary of $415,000, which amount is subject to periodic review by the Board or the Compensation Committee.

Mr. Jackson is eligible to receive an annual cash bonus award in an amount up to 40% of his base salary upon achievement of agreed upon performance targets. The bonus will be determined by the Board or the Compensation Committee and paid annually by March 15 in the year following the performance year on which such bonus is based. For the year ended December 31, 2022, there was no bonus earned.

In accordance with the terms of the employment agreement, Mr. Jackson is entitled to receive equity awards, consisting of a time-based nonqualified stock option, which we refer to as the Jackson Option Grant, covering 33,239 shares of common stock, 25% of which will vest on the first anniversary of the employment agreement’s effective date, and the remainder will vest ratably on a monthly basis over the three-year period thereafter. Vesting generally requires Mr. Jackson’s continued employment through the relevant vesting date.

If Mr. Jackson’s employment is terminated by us without Cause or by Mr. Jackson for Good Reason (each such capitalized term as defined in the employment agreement), we will pay Mr. Jackson all amounts accrued but unpaid as of the effective date of such termination, as well as continuation of his salary and benefits for the following nine month period (such period, the “Severance Period”). Notwithstanding the foregoing, if a termination without Cause or for Good Reason occurs within three months before or twelve months after a Change in Control (as defined in the employment agreement), Mr. Jackson will receive the benefits described in the preceding sentence, but the Severance Period shall run for a period of twelve months, and, in addition, Mr. Jackson will receive a lump-sum payment of his target bonus and the Jackson Option Grant shall become fully vested. Any such severance benefits under the employment agreement are contingent on Mr. Jackson entering into and not revoking a general release of claims in favor of our company.

The employment agreement provides for (a) reimbursement of reasonable business expenses, (b) participation in our benefit plans and (c) paid vacation days in accordance with our policies, as in effect from time to time, and up to an additional seven floating paid vacation days a year.

The employment agreement contains customary covenants related to non-solicitation for one year following termination of employment, as well as customary covenants related to non-competition, confidentiality, inventions and intellectual property rights.

We had entered into an employment agreement, effective as of September 20, 2021, with Roger Sidhu with respect to terms of his employment as our Chief Medical Officer. The employment agreement provided for at-will employment of Dr. Sidhu as our Chief Medical Officer for a term commencing on September 20, 2021 and continuing until terminated by us or Dr. Sidhu. Dr. Sidhu resigned as our Chief Medical Officer effective January 31, 2023.

Under the terms of the employment agreement, we paid Dr. Sidhu an annual base salary of $447,200, which amount was subject to annual review by the Board or the Compensation Committee and subject to adjustment to reflect market practices among our peers in the sole discretion of the Board or the Compensation Committee.

Dr. Sidhu was eligible to receive an annual cash bonus award in an amount up to 40% of his base salary upon achievement of reasonable performance targets set by the board or the Compensation Committee, each in its sole discretion. The bonus would be determined by the Board or the Compensation Committee and paid annually in March in the year following the performance year on which such bonus was based. For the year ended December 31, 2021 we paid Dr. Sidhu a $48,277 cash bonus.

In accordance with the terms of the employment agreement, we granted to Dr. Sidhu, effective as of September 20, 2021, a time-based nonqualified stock option, which we refer to as the Sidhu Option Grant, and a time-based restricted stock unit grant, which we refer to as the RSU Grant. The Sidhu Option Grant covered 8,065 shares of common stock, and the RSU Grant covered 4,032 shares of common stock. The Sidhu Option Grant and the RSU Grant each vested over four years, with vesting generally subject to Dr. Sidhu’s continued employment through the relevant vesting date. Consistent with the employment inducement grant rules set forth in Section 711(a) of the NYSE American LLC Company Guide, the equity award to Dr. Sidhu was made as an inducement material to his entering into employment with us and was approved by the Compensation Committee without need for stockholder approval.

If Dr. Sidhu’s employment was terminated by us without Cause or by Dr. Sidhu for Good Reason (each such capitalized term as defined in the employment agreement), he would be entitled to, among other things, continued base salary for nine months following the termination date and the total monthly cost of health care continuation coverage pursuant to COBRA for such period. Notwithstanding the foregoing, if a termination without Cause or for Good Reason occurs within ninety days before or twelve months after a Change in Control (as defined in the employment agreement), Dr. Sidhu would become entitled to (a) receive the continued-based salary and total monthly cost of health care continuation coverage described in the preceding sentence for a period of twelve months rather than nine months, (b) receive a lump sum payment of his target annual bonus and (c) accelerated vesting in full of the Sidhu Option Grant and the RSU Grant. Any of such severance benefits under the employment agreement are contingent on Dr. Sidhu entering into and not revoking a general release of claims in favor of our company.

The employment agreement provided for (a) reimbursement of reasonable business expenses, (b) participation in our benefit plans and (c) twenty paid vacation days per year.

The employment agreement also contained customary covenants related to non-competition and non-solicitation for one year following termination of employment, as well as customary covenants related to confidentiality, inventions and intellectual property rights.

On March 11, 2022, we issued Dr. Sidhu a performance-based restricted stock unit grant (the “Sidhu PSU Grant”). The Sidhu PSU Grant covered 7,108 shares of common stock and were subject to the achievement of four performance goals, which were weighted equally. Once a performance goal was achieved, the tranche of shares allocated to that performance goal would be earned and would begin to vest annually over a three-year period beginning on the date the performance goal was achieved subject to Dr. Sidhu’s continued employment through the relevant vesting date. If a performance goal was not achieved, then tranche of shares allocated to that performance goal would be unearned and forfeited. As of December 31, 2022, none of the performance goals were achieved, and as a result, the shares covered under the Sidhu PSU Grant were cancelled.

There was no separation agreement entered into upon Dr. Sidhu’s voluntary resignation effective January 31, 2023.

We entered into an employment agreement, dated June 5, 2021 and effective as of June 28, 2021, with Kevin A. D’Amour with respect to terms of his employment as our Chief Scientific Officer. The employment agreement provided for our at-will employment of Dr. D’Amour as our Chief Scientific Officer for a term commencing on June 28, 2021 and continuing until terminated by us or Dr. D’Amour. Dr. D’Amour resigned as our Chief Scientific Officer effective August 26, 2022.

Under the terms of the employment agreement, we paid Dr. D’Amour an annual base salary of $415,000, which amount was subject to annual review by the Board or the Compensation Committee and subject to adjustment to reflect market practices among our peers in the sole discretion of the Board or the Compensation Committee.

Dr. D’Amour was eligible to receive an annual cash bonus award in an amount up to 40% of his base salary upon achievement of reasonable performance targets set by the Board or the Compensation Committee, each in its sole discretion. The bonus would be determined by the Board or the Compensation Committee and paid annually in March in the year following the performance year on which such bonus was based. For the year ended December 31, 2021 we paid Dr. D’Amour a $84,886 cash bonus. We additionally granted certain equity awards to Dr. D’Amour under his employment agreement.

Effective August 26, 2022, Dr. D’Amour resigned as an employee. Upon the effective date of his resignation, we entered into a Separation Agreement and General Release with Dr. D’Amour (the “D’Amour Separation Agreement”), pursuant to which Dr. D’Amour resigned from his position as Chief Scientific Officer. In consideration

for Dr. D’Amour’s execution of the D’Amour Separation Agreement and non-revocation of a waiver and release of claims relating thereto, Dr. D’Amour was entitled to the following benefits under the D’Amour Separation Agreement:

Under the D’Amour Separation Agreement, Dr. D’Amour agreed to cooperate with and assist us regarding certain matters and transitioning his employment duties and responsibilities. Subject to certain exceptions and limitations, the D’Amour Separation Agreement included a general release of claims by Dr. D’Amour in favor of us and certain related persons and parties, and customary confidentiality and mutual non-disparagement provisions. The D’Amour Separation Agreement also included certain other customary representations, warranties and covenants of Dr. D’Amour, and provided for reimbursement of certain expenses incurred by Dr D’Amour. The D’Amour Separation Agreement superseded all other agreements or arrangements between Dr. D’Amour and us regarding the subject matter of the agreement, including those with respect to severance payments and benefits.

The following table summarizes the number of shares of our common stock underlying outstanding equity incentive plan awards for each named executive officer as of December 31, 2022.

Our Insider Trading Policy prohibits our directors, officers, employees, family members of such persons and entities controlled by such persons from engaging in hedging, short sales, or trading in publicly traded put or call options with respect to our securities. Additionally, such policy prohibits the same persons from purchasing our securities on margin, borrowing against any account in which our securities are held, or pledging our securities as collateral for a loan.

Our Compensation Committee assesses and monitors whether any of our compensation policies and programs is reasonably likely to have a material adverse effect on our Company. The Compensation Committee and management do not believe that the Company presently maintains compensation policies or practices that are reasonably likely to have a material adverse effect on the Company’s risk management or create incentives that could lead to excessive or inappropriate risk taking by employees. In reaching this conclusion, the Compensation Committee considered all components of our compensation program and assessed any associated risks. The Compensation Committee also considered the various strategies and measures employed by the company that mitigate such risk, including: (i) the overall balance achieved through our use of a mix of cash and equity, annual and long-term incentives and time-and performance-based compensation; (ii) our use of multi-year vesting periods for equity grants; and (ii) the oversight exercised by the Compensation Committee over the performance metrics and results under the Restated Plan and the 2021 Inducement Plan.

In accordance with rules adopted by the SEC pursuant to the Dodd-Frank Wall Street Reform and Consumer Protection Act of 2010, we provide the following disclosure regarding executive “compensation actually paid” (“CAP”) and certain Company performance for the fiscal years listed below.

The following table provides the information required for our principal executive officers (“PEOs”) and our non-PEO NEOs for each of the fiscal years ended December 31, 2022 and 2021 (the “2022 fiscal year” and the “2021 fiscal year”, respectively), along with the financial information required to be disclosed for each such fiscal year by Item 402(v) of Regulation S-K.

The graphs below reflect the relationship between the PEO and average non-PEO NEO CAP and the Company’s cumulative indexed Total Shareholder Return (“TSR”) (assuming an initial fixed investment of $100) for the 2022 and 2021 fiscal years:

PEO CAP vs TSR (January 1, 2021 – December 31, 2022)

 

Average Other NEO CAP vs TSR (January 1, 2021 – December 31, 2022)

 

The graph below reflects the relationship between the PEO and average non-PEO NEO CAP and the Company’s net income for the applicable reporting year. As a pre-commercial biotechnology company, we do not tie executive compensation to net income performance, and we do not have other financial metrics that are used to determine executive compensation. See the “—Narrative to Summary Compensation Table” for more information regarding how we compensate our NEOs.

 

We compensate our non-employee directors for their service in such capacity with annual retainers and equity compensation as described below. Directors who are also our employees do not receive any additional compensation for their services as directors. We do not pay fees to any of our directors for meeting attendance.

The Board and the Compensation Committee designed our non-employee director compensation program to reward directors for their contributions to our success, align the director compensation program with stockholder interests, and provide competitive compensation necessary to attract and retain high quality non-employee directors. The Compensation Committee expects to review director compensation periodically to ensure that director compensation remains competitive such that we can recruit and retain qualified directors.

The following table provides summary information concerning compensation paid or accrued by us to or on behalf of our non-employee directors for services rendered to us during the last fiscal year.

As of December 31, 2022, our non-employee directors had the following options outstanding:

The Nominating and Corporate Governance Committee recommended for nomination, and the Board of Directors nominated the following persons for election as members of our Board of Directors at the Annual Meeting of stockholders.

Charles Cherington

Matthew Angel

Nicholas J. Singer

Gregory Fiore

William Wexler

The section titled “Directors & Executive Officers” beginning on page 7 of this Proxy Statement contains more information about the leadership skills and other experience that caused the Nominating and Corporate Governance Committee and the Board of Directors to determine that these nominees should serve as directors of the Company.

We believe that each of these directors possesses the experience, skills, and qualities to fully perform his duties as a director and contribute to our success. Our directors have been nominated because they possess the highest standards of personal integrity, interpersonal and communication skills, are highly accomplished in their fields, understand the interests and issues that are important to our stockholders, and are able to dedicate sufficient time to fulfilling their obligations as directors. Our directors as a group complement each other with their respective experiences, skills, and qualities. While our directors make up a diverse group in terms of age, gender and professional experience, together they comprise a cohesive body in terms of Board process and collaboration.

Vote Required. Under our Bylaws, if a quorum is present, the directors will be elected by a plurality of the votes of shares present and entitled to vote. Accordingly, the nominees who receive the largest number of votes cast will be elected.

THE BOARD OF DIRECTORS RECOMMENDS A VOTE “FOR” EACH OF THE DIRECTOR NOMINEES.

Our Audit Committee selected and appointed Grant Thornton LLP (“Grant Thornton”) as our independent registered public accounting firm for the 2023 fiscal year. In selecting Grant Thornton as the Company’s independent registered public accounting firm for 2023, the Audit Committee considered several factors, including:

Although ratification is not required by our Bylaws or otherwise, the Board is submitting the appointment of Grant Thornton to our stockholders for ratification. The Audit Committee will consider the outcome of this vote in future deliberations regarding the appointment of our independent registered public accounting firm; however, the Audit Committee is solely responsible for the appointment and termination of our auditors and may do so at its discretion.

A representative from Grant Thornton is expected to attend the Annual Meeting of stockholders and will have the opportunity to make a statement, if he or she desires to do so, and answer questions, if any.

Vote Required. If a quorum is present, ratification of the appointment of our independent registered public accounting firm requires that a majority of the votes cast at the Annual Meeting are cast “FOR” ratification.

THE BOARD OF DIRECTORS RECOMMENDS A VOTE “FOR” RATIFICATION OF THE APPOINTMENT OF GRANT THORNTON AS OUR INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM FOR THE 2023 FISCAL YEAR.

On January 18, 2022, we notified Marcum LLP (“Marcum”) that it would be dismissed as our independent registered public accounting firm effective after the completion of Marcum’s audit of our financial statements for the year ended December 31, 2021. The Audit Committee approved Marcum’s dismissal on January 18, 2022.

Marcum performed audits of our consolidated financial statements for the years ended December 31, 2021 and 2020. Marcum’s reports for such years did not contain an adverse opinion or a disclaimer of opinion and were not qualified or modified as to uncertainty, audit scope, or accounting principles. During the two years ended December 31, 2021, and from December 31, 2020 through January 24, 2022, there were no (i) disagreements (as defined in Item 304(a)(1)(iv) of Regulation S-K and the related instructions to Item 304 of Regulation S-K promulgated by the SEC pursuant to the Exchange Act) between us and Marcum on any matter of accounting principles or practices, financial statement disclosure, or auditing scope or procedure, which disagreements, if not resolved to satisfaction of Marcum, would have caused Marcum to make reference to the subject matter of such disagreements in connection with its report, or (ii) “reportable events,” as described in Item 304(a)(1)(v) of Regulation S-K, that would require disclosure under Item 304(a)(1)(v) of Regulation S-K, except for the material weaknesses previously reported in our Quarterly Report on Form 10-Q for the period ended September 30, 2021 related to (a) segregation of duties and (b) documentation of policies and procedures critical to the accomplishment of financial reporting objectives. We previously furnished Marcum with a copy of the disclosure under this heading “Change in Certifying Accountant” prior to filing a Current Report on Form 8-K containing such disclosure with the SEC on January 24, 2022 and requested that Marcum furnish it with a letter addressed to the SEC stating whether or not it agreed with the statements made by us in such Current Report on Form 8-K insofar as they related to Marcum’s audit services and engagement as our independent registered public accounting firm. A copy of Marcum’s letter concurring with the foregoing disclosures was attached as Exhibit 16.1 to the Current Report on Form 8-K filed by us on January 24, 2022. Marcum’s dismissal became effective on April 15, 2022, and no events had occurred since the filing of such Form 8-K that would have required the filing of an amendment to such Form 8-K.

On January 18, 2022, we notified Grant Thornton LLP (“Grant Thornton”) that the Audit Committee had selected Grant Thornton to serve as our independent registered public accounting firm for the fiscal year ending December 31, 2022 and related interim periods, and Grant Thornton’s engagement became effective on April 18, 2022.

During the two years ended December 31, 2021 and from December 31, 2019 through April 19, 2022 (the date on which we filed a Current Report on Form 8-K, reporting the respective effective dates of Marcum’s dismissal and Grant Thornton’s engagement), neither we nor anyone acting on its behalf has consulted Grant Thornton regarding either: (i) the application of accounting principles to a specified transaction, either completed or proposed; or the type of audit opinion that might be rendered on our financial statements, and no written report or oral advice was provided to us by Grant Thornton that Grant Thornton concluded was an important factor considered by us in reaching a decision as to an accounting, auditing or financial reporting issue; or (ii) any matter that was either subject of a disagreement, as that term is defined in Item 304 (a)(1)(iv) of Regulation S-K and the related instructions to Item 304 of Regulation S-K, or a “reportable event,” as that term is described in Item 304(a)(1)(v) of Regulation S-K.

The table below summarizes the fees and expenses billed to us by Grant Thornton and Marcum for the years ended December 31, 2022 and 2021.

Audit Fees. Audit fees consist of services rendered by an independent registered public accounting firm for the audit of our consolidated financial statements (including tax services performed to fulfill the auditor’s responsibility under generally accepted auditing standards) and our internal control over financial reporting, reviews of the interim financial statements included in Forms 10-Q and includes services that generally only an external auditor can reasonably provide, such as comfort letters, statutory audits, attest services, consents and assistance with and review of documents filed with the SEC.

Audit-Related Fees. Audit-related fees consist of assurance and related services (e.g., due diligence) by an external auditor that are reasonably related to the audit or review of financial statements, including employee benefit plan audits, due diligence related to mergers and acquisitions, accounting consultations and audits in connection with proposed or consummated acquisitions, internal control reviews, attest services related to financial reporting that are not required by statute or regulation, and consultation concerning financial accounting and reporting standards.

Tax Fees. Tax fees consist of services rendered by an external auditor for tax compliance, tax consulting and tax planning.

All Other Fees. All other fees are for any other permissible work that is not an Audit, Audit-Related or Tax Fee.

All audit and permissible non-audit services provided by the independent auditors are pre-approved by the Audit Committee (or the Chair of the Audit Committee, pursuant to a delegation of authority). These services may include audit services, audit-related services, tax services and other services. Pre-approval is generally provided for up to one year and any pre-approval is detailed as to the particular service or category of services and is generally subject to a specific budget. The independent auditors and management are required to periodically report to the Audit Committee regarding the extent of services provided by the independent auditors in accordance with this pre-approval, and the fees for the services performed to date. The Audit Committee may also pre-approve particular services on a case-by-case basis.

On April 5, 2023, we entered into the Lincoln Park Purchase Agreement with Lincoln Park Capital Fund, LLC (“Lincoln Park”) and a related registration rights agreement (the “Registration Rights Agreement”). Pursuant to the Lincoln Park Purchase Agreement, Lincoln Park has agreed to purchase from us up to an aggregate of $10.0 million of shares our common stock. We are submitting this Proposal 3 to our stockholders in order to obtain the requisite stockholder authorization in accordance with Nasdaq listing rules, specifically Rule 5635(d), to issue and sell shares of our common stock to Lincoln Park in excess of 20% of the outstanding shares of our common stock as of the date we entered into the Lincoln Park Purchase Agreement. Nothing contained in the Lincoln Park Purchase Agreement obligates us to issue and sell any shares, other than the Commitment Shares (as defined below), and any sales by us under the Lincoln Park Purchase Agreement would be made at our sole election and in our discretion, subject to the terms and satisfaction of the conditions contained in the Lincoln Park Purchase Agreement.

Under the terms and subject to the conditions of the Lincoln Park Purchase Agreement, we have the right, but not the obligation, to sell to Lincoln Park, and Lincoln Park is obligated to purchase, up to $10.0 million of shares of common stock. Such sales of common stock by us, if any, are subject to certain limitations, and may occur from time to time, at our sole discretion, over the 24-month period commencing after the satisfaction of certain conditions set forth in the Lincoln Park Purchase Agreement, including the effectiveness of a registration statement that we filed with the SEC in accordance with the terms of the Registration Rights Agreement, pursuant to which we have registered for resale by Lincoln Park the shares of common stock that we may issue and sell under the Lincoln Park Purchase Agreement.

Under the Lincoln Park Purchase Agreement, for a period of up to 24-months following the date on which all applicable conditions have been satisfied, on any business day that we select on which the closing sale price of our common stock equals or exceeds $0.50 per share, we may direct Lincoln Park to purchase up to 30,000 shares of our common stock in a “Regular Purchase” on such business day; provided, however, that (i) the Regular Purchase may be increased to up to 40,000 shares of our common stock if the closing sale price of our common stock is not below $4.50 on the purchase date, (ii) the Regular Purchase may be increased to up to 50,000 shares of our common stock if the closing sale price of our common stock is not below $6.00 on the purchase date and (iii) the Regular Purchase may be increased to up to 90,000 shares of our common stock if the closing sale price of our common stock is not below $5.00 on the purchase date (such share amount limitation, the “Regular Purchase Share Limit”). In each case, Lincoln Park’s maximum commitment in any single Regular Purchase may not exceed $1.0 million. The Regular Purchase Share Limit is generally subject to proportionate adjustment for any reorganization, recapitalization, non-cash dividend, stock split, reverse stock split or other similar transaction as provided in the Lincoln Park Purchase Agreement.

The purchase price per share for each such Regular Purchase will be equal to the lower of: (i) the lowest sale price for our common stock on the purchase date for such Regular Purchase; and (ii) the arithmetic average of the three lowest closing sale prices for our common stock during the 10 consecutive business days ending on the business day immediately preceding the purchase date for such Regular Purchase.

In addition to Regular Purchases described above, on any purchase date for a Regular Purchase on which we have properly submitted a Regular Purchase notice directing Lincoln Park to purchase the maximum number of shares of our common stock that we are then permitted to include in a single Regular Purchase notice (and provided all shares of common stock subject to all prior Regular Purchases, Accelerated Purchases (as defined below) and Additional Accelerated Purchases (as defined below) that we have effected under the Lincoln Park Purchase Agreement prior to such purchase date, if any, have been received by Lincoln Park before we deliver notice to Lincoln Park for such Accelerated Purchase in accordance with the Lincoln Park Purchase Agreement), we may, by written notice delivered by us to Lincoln Park simultaneously with such Regular Purchase notice for such corresponding Regular Purchase, direct Lincoln Park to purchase an additional amount of our common stock, which we refer to as an “Accelerated Purchase,” on the next business day following such purchase date for such corresponding Regular Purchase, which we refer to as the “Accelerated Purchase Date,” not to exceed the lesser of: (i) 30% of the aggregate number of shares of our common stock traded during all or, if certain trading volume or market price thresholds specified in the Lincoln Park Purchase Agreement are crossed on the applicable Accelerated Purchase Date, the portion of the normal trading hours the applicable Accelerated Purchase Date prior to such time that any one of such thresholds is crossed, which

period of time on the applicable Accelerated Purchase Date we refer to as the “Accelerated Purchase Measurement Period”; and (ii) 300% of the number of shares of common stock purchased pursuant to the corresponding Regular Purchase.

The purchase price per share for the shares of common stock subject to an Accelerated Purchase will be equal to 96% of the lower of: (i) the volume weighted average price of our common stock during the Accelerated Purchase Measurement Period on the applicable Accelerated Purchase Date; and (ii) the closing sale price of our common stock on the applicable Accelerated Purchase Date.

We may also direct Lincoln Park, by written notice delivered to Lincoln Park not later than 1:00 p.m., Eastern time, on an Accelerated Purchase Date (and provided all shares of common stock subject to all prior Regular Purchases, Accelerated Purchases and Additional Accelerated Purchases that we have effected under the Lincoln Park Purchase Agreement, including those prior Accelerated Purchases and Additional Accelerated Purchases effected on the same Accelerated Purchase Date as the applicable Additional Accelerated Purchase, if any, have been received by Lincoln Park in accordance with the Lincoln Park Purchase Agreement before we deliver notice to Lincoln Park for such Additional Accelerated Purchase), to purchase an additional amount of our common stock on such same Accelerated Purchase Date, which we refer to as an “Additional Accelerated Purchase,” of up to the lesser of: (i) 30% of the aggregate number of shares of our common stock traded during the portion of the normal trading hours on the applicable Accelerated Purchase Date determined in accordance with the Lincoln Park Purchase Agreement, which period of time on the applicable Accelerated Purchase Date we refer to as the Additional Accelerated Purchase Measurement Period; and (ii) three times the number of purchase shares purchased pursuant to the Regular Purchase corresponding to the Accelerated Purchase that was completed on such Accelerated Purchase date on which an Additional Accelerated Purchase notice was properly received.

The purchase price per share for the shares subject to an Additional Accelerated Purchase will be equal to 96% of the lower of: (i) the volume weighted average price of our common stock during the applicable Additional Accelerated Purchase Measurement Period for such Additional Accelerated Purchase; and (ii) the closing sale price of our common stock on the applicable same Accelerated Purchase Date.

As consideration for Lincoln Park’s commitment to purchase shares of common stock in accordance with the Lincoln Park Purchase Agreement, the Company issued 73,659 shares of common stock to Lincoln Park as a commitment fee (the “Commitment Shares”).

In all instances, we may not sell shares of our common stock to Lincoln Park under the Lincoln Park Purchase Agreement if it would result in Lincoln Park beneficially owning more than 4.99% of our common stock. There are no upper limits on the price per share that Lincoln Park must pay for shares of common stock.

We currently intend to use the net proceeds from the sale of common stock to Lincoln Park for general corporate purposes.

As a result of the listing of our common stock on The Nasdaq Capital Market, issuances of our common stock are subject to the Nasdaq Listing Rules, including Rule 5635(d), which requires us to obtain stockholder approval prior to the issuance of securities in connection with a transaction, other than a public offering, involving the sale, issuance or potential issuance by us of more than 19.99% of our outstanding shares of our common stock (or securities convertible into or exercisable for shares of our common stock) at a price less than the lower of: (i) the closing price (as reflected on Nasdaq.com) immediately preceding the signing of the binding agreement; or (ii) the average closing price of the common stock (as reflected on Nasdaq.com) for the five trading days immediately preceding the signing of the binding agreement (the “Nasdaq 20% Rule”).

Under the Nasdaq 20% Rule, in no event may we issue or sell to Lincoln Park under the Lincoln Park Purchase Agreement more than 19.99% of the shares of our common stock outstanding immediately prior to the execution of the Lincoln Park Purchase Agreement (which was 1,024,901 shares, based on 5,127,070 of our shares outstanding immediately prior to the execution of the Lincoln Park Purchase Agreement) (the “Exchange Cap”), unless (i) the Company first obtains stockholder approval to issue shares of common stock in excess of the Exchange Cap in accordance with applicable Nasdaq listing rules, or (ii) at the time the Company has issued shares of common stock equal to the Exchange Cap and at all times thereafter, the average price per share of common stock for all shares of common stock sold by the Company to Lincoln Park under the Lincoln Park Purchase Agreement equals or exceeds $3.6094 per share (representing the lower of the official closing price of the common stock on Nasdaq on the trading

day immediately preceding the date of the Lincoln Park Purchase Agreement and the average official closing price of the common stock on Nasdaq for the five consecutive trading days ending on the trading day immediately preceding the date of the Lincoln Park Purchase Agreement, as adjusted under applicable Nasdaq rules to take into account the issuance of the Commitment Shares) (the “LP Minimum Price”), such that the Exchange Cap limitation would no longer apply to issuances and sales of common stock by the Company to Lincoln Park under the Lincoln Park Purchase Agreement under the Nasdaq 20% Rule. In any event, the Lincoln Park Purchase Agreement specifically provides that we may not issue or sell any shares of our common stock under the Lincoln Park Purchase Agreement if such issuance or sale would breach any applicable Nasdaq rules.

Based on the closing sale price of our common stock as reported on Nasdaq on April 26, 2023, to fully utilize the $10 million amount available to us under the Lincoln Park Purchase Agreement, we would need to issue [•] shares of common stock to Lincoln Park, which would be in excess of the Nasdaq 20% Rule. Accordingly, in order to be able to sell to Lincoln Park the full amount available under the Lincoln Park Purchase Agreement at a price less than the LP Minimum Price, we are seeking stockholder approval to issue greater than 20% of our outstanding shares as of the date we entered into the agreement with Lincoln Park, which issuance would be effected under the Lincoln Park Purchase Agreement in accordance with its terms.

If the stockholders do not approve this Proposal No. 3, then we will be unable to issue shares of common stock to Lincoln Park pursuant to the Lincoln Park Purchase Agreement in excess of the Exchange Cap if sold at a price less than the LP Minimum Price.

If we obtain stockholder approval as requested in this Proposal No. 3, then we would no longer be subject to the Nasdaq 20% Rule restriction with respect to the issuance and sale of common stock to Lincoln Park under the Lincoln Park Purchase Agreement. If this Proposal No. 3 is approved by our stockholders, we would be able to issue more than the Exchange Cap (or 1,024,901 shares) to Lincoln Park under the Lincoln Park Purchase Agreement at a price less than the LP Minimum Price. The maximum number of shares of common stock that we may issue and sell to Lincoln Park under the Lincoln Park Purchase Agreement would fluctuate from time to time based on the price of our common stock. Assuming that our stockholders approve this Proposal No. 3, and assuming and the total number of shares issuable under the Lincoln Park Purchase Agreement were issued on April 26, 2023 at the closing price on that date, a total of [•] additional shares of common stock would be issuable to Lincoln Park, which have an approximate value of $[•] million.

In addition, these additional shares of common stock that we could issue to Lincoln Park will result in greater dilution to existing stockholders and may result in a decline in our stock price or greater price volatility.

Each such additional share of common stock that would be issuable to Lincoln Park under the Lincoln Park Purchase Agreement would have the same rights and privileges as each share of our currently authorized common stock.

If a quorum is present, approval, for purposes of complying with Nasdaq Listing Rule 5635(d), of the potential issuance and sale of more than 20% of the Company’s issued and outstanding common stock pursuant to the Lincoln Park Purchase Agreement requires that a majority of the votes cast at the Annual Meeting are cast “FOR” approval.

THE BOARD OF DIRECTORS RECOMMENDS A VOTE “FOR” THE APPROVAL OF THE POTENTIAL ISSUANCE AND SALE OF MORE THAN 20% OF OUR OUTSTANDING COMMON STOCK PURSUANT TO THE LINCOLN PARK PURCHASE AGREEMENT.

The Company’s stockholders are being asked to approve an amendment (the “Restated Plan Amendment”) to the Company’s Restated 2020 Stock Incentive Plan (the “Restated Plan”), which would increase the number of shares of common stock reserved for issuance under the Restated Plan from 680,599 to [•]. A copy of the Restated Plan, as amended by the Restated Plan Amendment, is set forth in this Proxy Statement as Appendix A.

We are seeking approval of the Restated Plan Amendment to comply with the Nasdaq stockholder approval requirements applicable to material amendments to equity plans. Under Nasdaq listing rules, the Board may not increase the number of shares of common stock issuable under the Restated Plan (except in the case of a recapitalization, stock split or similar event) without stockholder approval. The Board believes that the Restated Plan Amendment is necessary to continue to enable the Company to attract and retain qualified directors, officers, employees and consultants for the Company by making available additional shares under the Restated Plan, as well as helping to align the interests of management, employees and stockholders to create long-term stockholder value.

The Restated Plan was originally adopted by the Board on May 20, 2021 and approved by our stockholders on August 20, 2021 at the Company’s 2021 annual meeting of the stockholders. On April [•], 2023, upon the recommendation of the Compensation Committee, the Board unanimously approved the Restated Plan Amendment and recommended that it be submitted to our stockholders for approval. As of April 26, 2023, awards representing an aggregate of 577,872 shares of common stock, including shares that had been cancelled, forfeited or otherwise put back into the pool for the Restated Plan, had been issued under the Restated Plan. Approximately 215,329 shares remain available for issuance under the Restated Plan. The Company is seeking stockholder approval to increase the total number of shares of common stock issuable under the Restated Plan to [•] (or [•] additional shares of common stock).

If the Restated Plan Amendment is approved by our stockholders at the Annual Meeting, it will become effective on the date of the Annual Meeting, and the total number of shares of our common stock that will be reserved for issuance under the Restated Plan will be [•] shares (representing approximately [•]% of our outstanding common stock as of April 26, 2023) plus any additional shares added pursuant to expiration, termination or forfeiture of outstanding awards under the Restated Plan. If the Restated Plan Amendment is not approved by our stockholders at the Annual Meeting, the Restated Plan will remain in effect as it presently exists.

The Board reviewed the number of shares of common stock covered by, and reserved for issuance under, the Restated Plan, and determined that it is appropriate to increase the number of shares of common stock authorized for issuance under the Restated Plan. In setting the number of shares authorized under the Restated Plan Amendment, the Compensation Committee and the Board considered the following:

As of April 26, 2023 the number of shares of common stock that remained available for issuance under the Restated Plan was 215,329 shares. As of April 26, 2023, options to purchase an aggregate of 464,810 shares of our common stock were outstanding under the Restated Plan, with a weighted average exercise price of $10.80 per share and a weighted average remaining contractual life of 9.5 years. Our Board believes that an increase in the Restated Plan’s share reserve is necessary to ensure that a sufficient reserve of common stock is available for issuance to make competitive grants through at least [•]. The additional [•] shares that would be made available for grant if stockholders approve the Restated Plan Amendment, together with the remaining shares under the Restated Plan, represent the shares the Company anticipates needing under normal circumstances.

In determining the number of shares to request for stockholder approval under the Restated Plan Amendment, the Compensation Committee and the Board considered various other factors, including our current stock price and prior grants made to our employees. Since the Restated Plan’s approval by our stockholders in 2021, we have been able to incentivize our workforce and attract qualified employees, directors, officers and consultants. Because of the limited number of shares

of common stock that remain available for issuance under the Restated Plan, our ability to use long-term equity-based compensation as a significant component of our overall compensation would be significantly restricted if the stockholders do not approve the Restated Plan Amendment. Additionally, our inability to issue awards under the Restated Plan could require that we pay more compensation in the form of cash, which would limit the amount of cash that we could otherwise devote to other business purposes, and cash compensation would not necessarily incentivize recipients to focus on our long-term performance.

After consideration of these factors, the Compensation Committee and Board determined that an increase of [•] shares available under the Restated Plan would be appropriate to allow us to continue to grant equity-based compensation at levels we deem appropriate for approximately one to two years. As noted above, if our stockholders do not approve the Restated Plan Amendment, in order to remain competitive in hiring and retaining high quality employees, it may become necessary to replace components of compensation previously awarded in equity with cash. We do not believe increasing cash compensation to make up for any shortfall in equity compensation would be practical or advisable because we believe that a combination of equity awards and cash compensation provide a more effective compensation strategy than cash alone for attracting, retaining and motivating our employees long-term and aligning employees’ and stockholders’ interests. In addition, any significant increase in cash compensation in lieu of equity awards could substantially increase our operating expenses and increase the negative cash flow from our operations, which could adversely affect our business results and could adversely affect our business strategy.

The following is a summary of the material provisions of the Restated Plan, as amended by the Restated Plan Amendment. The following summary does not purport to be a complete description of all the provisions of the Restated Plan and the Restated Plan Amendment and is qualified in its entirety by reference to the complete text of the Restated Plan, which we filed as Exhibit 10.29 to our Annual Report on Form 10-K for the year ended December 31, 2022, and the Restated Plan Amendment, a form of which is set forth in Appendix A to this Proxy Statement.

The Restated Plan is administered and interpreted by our Compensation Committee. The Compensation Committee determines the persons to whom awards issuable under the Restated Plan may be granted. The Compensation Committee may also establish rules and regulations for the administration of the Restated Plan and amendments or modifications to outstanding awards. The Compensation Committee may delegate authority to officers or employees to grant awards and execute award agreements, subject to applicable law and the Restated Plan.

Persons eligible to receive awards under the Restated Plan consist of our employees, officers, directors, consultants, independent contractors who, in the opinion of our Compensation Committee, are in a position to contribute to our success, or any other person who is determined by our Compensation Committee to be a prospective employee, officer, director, consultant, advisor or other individual service provider, any entity whose financials statements are required to be consolidated with the Company, and any other entity that our Compensation Committee determines to be an affiliate of the Company. As of April 26, 2023, we had nine full-time employees, which includes four research and development positions and five administrative positions. As awards under the Restated 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 under the Restated Plan, as amended by the Restated Plan Amendment.

Subject to approval of the Restated Plan Amendment, and further adjustment in certain circumstances as discussed below, the Restated Plan authorizes up to [•] shares of our common stock for issuance pursuant to its terms (including the additional [•] shares of our common stock that would be available if our stockholders approve the Restated Plan Amendment), plus any shares of our common stock subject to outstanding awards under the Restated Plan which are forfeited, expire or otherwise put back into the pool of the Restated Plan.

Incentive stock options (“ISOs”) that are intended to meet the requirements of Section 422 of the Internal Revenue Code (the “Code”) may be granted under the Restated Plan with respect to all of the shares of common stock authorized for issuance under the Restated Plan.

If any option or stock appreciation right (“SAR”) granted under the Restated Plan is terminated without having been exercised in full or if any award is forfeited, the number of shares of common stock as to which such option, SAR or award was terminated or forfeited will be available for future grants under the Restated Plan. Awards settled in cash will not count against the number of shares available for issuance under the Restated Plan; however, if any award is cancelled forfeited or terminated in order to pay the exercise price of a stock option, purchase price or any taxes or tax withholdings on an award, such shares will not be available for future awards under the Restated Plan.

The number of shares authorized for issuance under the Restated Plan and the foregoing share limitations are subject to customary adjustments for stock splits, stock dividends or similar transactions effected after the effective time of the Restated Plan.

Options granted under the Restated Plan may be either ISOs or nonstatutory stock options (“NSOs”), that do not meet the requirements of Section 422 of the Code. The Compensation Committee will determine the exercise price of options granted under the Restated Plan. The exercise price of options may not be less than the fair market value per share of common stock on the date of grant (or 110% of fair market value in the case of ISOs granted to a ten-percent stockholder).

If on the date of grant the common stock is listed on a stock exchange or is quoted on an automated quotation system, the fair market value will generally be the closing sale price on the last trading day before the date of grant. If no such prices are available, the fair market value will be determined in good faith by the Compensation Committee based on the reasonable application of a reasonable valuation method.

No option may be exercisable for more than 10 years (five years in the case of an ISO granted to a ten-percent stockholder) from the date of grant. Options granted under the Restated Plan are 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.

Generally, the option price may be paid (a) in cash or by certified check, bank draft or money order, (b) through delivery of shares of common stock having a fair market value equal to the purchase price, or (c) any other methods of payment that the Compensation Committee permits in its sole and absolute discretion, including a cashless exercise program.

The Compensation Committee may grant SARs under the Restated Plan. The Compensation Committee will determine the other terms applicable to SARs. The exercise price per share of a SAR will not be less than 100% of the fair market value of a share of common stock on the date of grant, as determined by the Compensation Committee. The maximum term of any SAR granted under the Restated Plan is 10 years from the date of grant. Generally, each SAR will entitle a participant upon exercise to an amount equal to:

Payment may be made in shares of common stock, in cash, or partly in common stock and partly in cash, all as determined by the Compensation Committee.

The Compensation Committee may award restricted common stock and/or restricted stock units under the Restated 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. Restricted stock units confer the right to receive shares of 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. The restrictions and conditions applicable to each award of restricted stock or restricted stock units may include performance-based conditions. Dividends with respect to restricted stock may be paid to the holder of the shares as and when dividends are paid to stockholders or at the time that the restricted stock vests, as determined by the Compensation Committee. Dividend equivalent amounts

may be paid with respect to restricted stock units either when cash dividends are paid to stockholders or when the units vest. Unless the Compensation Committee determines otherwise, holders of restricted stock have the right to vote the shares.

The Compensation Committee may award performance shares and/or performance units under the Restated Plan. Performance shares and performance units are awards, denominated in either shares or U.S. dollars, which are earned during a specified performance period subject to the attainment of performance criteria, 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.

The Compensation Committee may award other types of equity-based or cash-based awards under the Restated Plan, including the grant or offer for sale of shares of common stock that do not have vesting requirements and the right to receive one or more cash payments subject to satisfaction of such conditions as the Compensation Committee may impose.

No award option may be transferred other than by will or by the laws of descent and distribution, and during a recipient’s lifetime an option may be exercised only by the recipient. However, the Compensation Committee may permit the holder of an option, restricted stock or other award to transfer the option, restricted stock or other award to immediate family members.

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 Restated Plan) on any award, including (i) making some or all of the awards immediately exercisable or vested, (ii) terminating awards provided that the participant has the right immediately before the corporate transaction to exercise any vested award, eliminating or modifying the performance or other conditions of an award, or (iii) terminating all awards and providing for the cash settlement of an award for an equivalent cash value equal to the change in control price of any vested award (net of any exercise price).

The Board may at any time amend the Restated Plan for the purpose of satisfying the requirements of the Code, or other applicable law or regulation or for any other legal purpose, provided that, without the consent of stockholders, the Board may not (a) increase the number of shares of common stock available under the Restated Plan, (b) change the group of individuals eligible to receive awards or (c) extend the term of the Restated Plan.

A “new plan benefits” table, as described in the SEC’s proxy rules, is not provided, because the grant of options and other awards under the Restated Plan is discretionary, and we cannot determine now the specific number or type of options or awards to be granted in the future to any particular person or group.

Set forth below is a general description of the federal income tax consequences relating to awards granted under the Restated Plan.

The Restated Plan is not qualified under the provisions of section 401(a) of the Code and is not subject to any of the provisions of the Employee Retirement Income Security Act of 1974, as amended.

Treatment of Options. The Code treats ISOs and NSOs differently. As to both types of options, however, no income will be recognized to the optionee at the time of the grant of the options under the Restated Plan, nor will we be entitled to a tax deduction at that time.

Generally, upon exercise of a NSO (including an option intended to be an ISO but that has not continued to so qualify at the time of exercise), an optionee will recognize ordinary income tax on the excess of the fair market value of the

stock on the exercise date over the option price. We will be entitled to a tax deduction in an amount equal to the ordinary income recognized by the optionee in the fiscal year that includes the end of the optionee’s taxable year. We will be required to satisfy applicable withholding requirements in order to be entitled to a tax deduction. In general, if an optionee, in exercising a NSO, tenders shares of common stock in partial or full payment of the option price, no gain or loss will be recognized on the tender. However, if the tendered shares were previously acquired upon the exercise of an ISO and the tender is within two years from the date of grant or one year after the date of exercise of the ISO, the tender will be a disqualifying disposition of the shares acquired upon exercise of the ISO.

With respect to ISOs, there is no taxable income to an optionee at the time of exercise. However, the excess of the fair market value of the stock on the date of exercise over the exercise price will be taken into account in determining whether the “alternative minimum tax” will apply for the year of exercise. If the shares acquired upon exercise are held until at least two years from the date of grant and more than one year from the date of exercise, any gain or loss upon the sale of such shares, if held as capital assets, will be long-term capital gain or loss (measured by the difference between the sales price of the stock and the exercise price). Under current federal income tax law, a long-term capital gain will be taxed at a rate that is less than the maximum rate of tax on ordinary income. If the two-year and one year holding period requirements are not met (a “disqualifying disposition”), an optionee will recognize ordinary income in the year of disposition in an amount equal to the lesser of (a) the fair market value of the stock on the date of exercise minus the exercise price or (b) the amount realized on disposition minus the exercise price. The remainder of the gain will be treated as long-term capital gain, depending upon whether the stock has been held for more than a year. If an optionee makes a disqualifying disposition, we will be entitled to a tax deduction equal to the amount of ordinary income recognized by the optionee.

In general, if an optionee, in exercising an ISO, tenders shares of common stock in partial or full payment of the option price, no gain or loss will be recognized on the tender. However, if the tendered shares were previously acquired upon the exercise of another ISO and the tender is within two years from the date of grant or one year after the date of exercise of the other option, the tender will be a disqualifying disposition of the shares acquired upon exercise of the other option.

As noted above, the exercise of an ISO could subject an optionee to the alternative minimum tax. The application of the alternative minimum tax to any particular optionee depends upon the particular facts and circumstances that exist with respect to the optionee in the year of exercise. However, as a general rule, the amount by which the fair market value of the common stock on the date of exercise of an option exceeds the exercise price of the option will constitute an item of “adjustment” for purposes of determining the alternative minimum taxable income on which the alternative tax may be imposed. As such, this item will enter into the tax base on which the alternative minimum tax is computed and may therefore cause the alternative minimum tax to become applicable in any given year.

Treatment of Stock Appreciation Rights. Generally, the recipient of a SAR will not recognize any income upon grant of the SAR, nor will we be entitled to a deduction at that time. Upon exercise of a SAR, the holder will recognize ordinary income, and we generally will be entitled to a corresponding deduction, equal to the excess of fair market value of common stock at that time over the exercise price.

Treatment of Stock Awards. Generally, absent an election to be taxed currently under Section 83(b) of the Code (a “Section 83(b) Election”), there will be no federal income tax consequences to either the recipient or us upon the grant of a restricted stock award or award of performance shares. At the expiration of the restriction period and the satisfaction of any other restrictions applicable to the restricted shares, the recipient will recognize ordinary income and we generally will be entitled to a corresponding deduction equal to the fair market value of the common stock at that time. If a Section 83(b) Election is made within 30 days after the date the restricted stock award is granted, the recipient will recognize an amount of ordinary income at the time of the receipt of the restricted shares, and we generally will be entitled to a corresponding deduction, equal to the fair market value (determined without regard to applicable restrictions) of the shares at such time, less any amount paid by the recipient for the shares (if any). If a Section 83(b) Election is made, no additional income will be recognized by the recipient upon the lapse of restrictions on the shares (and prior to the sale of such shares), but, if the shares are subsequently forfeited, the recipient may not deduct the income that was recognized pursuant to the Section 83(b) Election at the time of the receipt of the shares.

The recipient of an unrestricted stock award will recognize ordinary income, and we generally will be entitled to a corresponding deduction, equal to the fair market value of common stock that is the subject of the award when the award is made.

The recipient of a restricted stock unit generally will recognize ordinary income as and when the units vest and are settled. The amount of the income will be equal to the fair market value of the shares of common stock issued at that time, and we will be entitled to a corresponding deduction. The recipient of a restricted stock unit will not be permitted to make a Section 83(b) Election with respect to such award.

The federal income tax consequences of performance share awards, performance unit awards, other cash-based awards and other stock-based awards will depend on the terms and conditions of those awards but, in general, participants will be required to recognize ordinary income in an amount equal to the cash and the fair market value of any fully vested shares of common stock paid, determined at the time of such payment, in connection with such awards.

Section 409A. The Restated Plan is intended to comply with Section 409A of the Code to the extent that such section would apply to any award under the Restated Plan. Section 409A of the Code governs the taxation of deferred compensation. Any participant that is granted an award that is deemed to be deferred compensation, such as a grant of restricted stock units that does not qualify for an exemption from Section 409A of the Code, and does not comply with Section 409A of the Code, could be subject to taxation on the award as soon as the award is no longer subject to a substantial risk of forfeiture (even if the award is not exercisable) and an additional 20% tax (and a further additional tax based upon an amount of interest determined under Section 409A of the Code) on the value of the award. Participants are urged to consult with their own tax advisors regarding the applicability of Section 409A of the Code to their awards.

Potential Limitations on Company Deductions. Section 162(m) of the Code generally disallows a tax deduction for compensation in excess of $1 million paid in a taxable year by a publicly held corporation to its chief executive officer and certain other “covered employees”. Our Board and the Compensation Committee intend to consider the potential impact of Section 162(m) on grants made under the Restated Plan but reserve the right to approve grants of options and other awards for an executive officer that exceed the deduction limit of Section 162(m) and, therefore, some options and other awards may not be fully deductible by us.

Tax Withholding. As and when appropriate, we shall have the right to require each optionee purchasing shares of common stock and each grantee receiving an award of shares of common stock under the Restated Plan to pay any federal, state or local taxes required by law to be withheld.

Importance of Consulting Tax Adviser. The information set forth above is a summary only and does not purport to be complete. In addition, the information is based upon current Federal income tax rules and therefore is subject to change when those rules change. Moreover, because the tax consequences to any recipient may depend on his or her particular situation, each participant should consult his or her tax adviser as to the Federal, state, local, foreign and other tax consequences of the grant or exercise of an award or the disposition of shares of common stock acquired as a result of an award.

The Company’s executive officers and the director nominees have an interest in this Proposal No. 4 to adopt the Restated Plan Amendment, as each is eligible to receive awards under the Restated Plan, as amended by the Restated Plan Amendment. The benefits that will be received by or allocated to eligible persons under the Restated Plan, as amended by the Restated Plan Amendment, including each of the current directors, each of the Named Executive Officers, the current executive officers as a group, the current directors who are not executive officers as a group, and all employees, including all current officers who are not executive officers, as a group, are discretionary and are not presently determinable.

Vote Required. If a quorum is present, approval of the Restated Plan Amendment requires that a majority of the votes cast at the Annual Meeting are cast “FOR” approval.

THE BOARD OF DIRECTORS RECOMMENDS A VOTE “FOR” APPROVAL OF THE RESTATED PLAN AMENDMENT.

The following report of the Audit Committee does not constitute soliciting material and should not be deemed filed with the SEC nor shall this information be incorporated by reference into any filing under the Securities Act or the Exchange Act, except to the extent that the Company specifically incorporates it by reference into a filing.

Our Audit Committee consists of Chair, William Wexler, and members, Charles Cherington and Nicholas J. Singer. The Board has determined that each Audit Committee member is “independent,” as independence for Audit Committee members is defined in the applicable Nasdaq listing standards and rules of the SEC. The Board also determined that all members of the Audit Committee are financially literate, and Mr. Singer has been designated as an Audit Committee financial expert, as such term is defined in Item 407 of Regulation S-K. Although designated as Audit Committee financial experts, the Audit Committee Chair and members are not accountants for the Company nor, under SEC rules, an “expert” for purposes of the liability provisions of the Securities Act or for any other purpose.

The role of the Audit Committee is to (a) oversee the accounting and financial reporting processes of the Company and the audits of the Company’s financial statements; (b) oversee the Company’s compliance with legal and regulatory requirements; (c) oversee the performance of the Company’s internal audit function; (d) take, or recommend that the Board of the Company take, appropriate action to oversee the qualifications, independence and performance of the Company’s independent auditors; and (e) prepare the report required by the rules of the SEC to be included in the Company’s annual proxy statement.

The Audit Committee influences the overall tone for quality financial reporting, sound internal controls, and ethical behavior. Management is responsible for the preparation, presentation and integrity of the Company’s financial statements, for the appropriateness of the accounting and reporting policies that are used by the Company, and for the establishment and effectiveness of internal controls and procedures designed to ensure compliance with accounting standards and applicable laws and regulations. The independent auditors are responsible for auditing the Company’s consolidated financial statements in accordance with the standards of the Public Company Accounting Oversight Board (“PCAOB”), expressing an opinion as to the conformity of such financial statements with generally accepted accounting principles, expressing an opinion on the effectiveness of internal control over financial reporting (when required), and for reviewing the Company’s interim consolidated financial statements.

The independent auditors report directly to the Audit Committee. The Audit Committee has the sole authority and responsibility to recommend to the Board the nomination of the independent auditors for approval by the stockholders on an annual basis. The Audit Committee is directly responsible for the appointment, retention, termination, compensation, retention, evaluation and oversight of the work of the independent auditors for the purpose of preparing or issuing an audit report or performing other audit, review or attest services for the Company.

In 2022, the Audit Committee met and held discussions with management and Grant Thornton, the Company’s independent registered public accounting firm. The Audit Committee discussed with management and Grant Thornton the Company’s audited consolidated financial statements and policies and procedures designed to reduce the likelihood of events of non-compliance with rules and regulations, including discussions of the quality, not just the acceptability, of accounting policies and principles, significant judgments and estimates, system of internal control over financial reporting, and clarity of disclosures, including items reported as Critical Auditing Matters in the report of the independent auditor. The Audit Committee reviewed the annual plan and scope of work to be performed by Grant Thornton, and met outside of the presence of management with Grant Thornton to discuss their respective audit results, evaluations of Eterna’s internal controls, and the overall quality of Eterna’s financial reporting. Consistent with the requirements of the Sarbanes-Oxley Act of 2002 and the rules promulgated thereunder, the Audit Committee discussed with Grant Thornton those matters required to be discussed pursuant to PCAOB Auditing Standard 1301, “Communications with Audit Committees,” and the rules of the SEC, and reviewed a letter from Grant Thornton disclosing such matters.

The Audit Committee also discussed with Grant Thornton the firm’s independence from the Company and its management team and reviewed the written disclosures and letter from Grant Thornton pursuant to applicable requirements of the PCAOB regarding the independent registered public accounting firm’s communications with the Audit Committee concerning independence, and considered the compatibility of non-audit services, if any, with Grant Thornton’s independence.

Based upon the reports and discussions described above, the Audit Committee, in accordance with its responsibilities, recommended to the Board that the audited consolidated financial statements be included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2022.

We will bear the cost of the solicitation of proxies on behalf of the Board. In addition to the use of the mail, proxies may be solicited by us personally, by telephone, or by similar means. None of our directors, officers, or employees will be specifically compensated for those activities. We do not expect to pay any compensation for the solicitation of proxies. However, we will reimburse brokerage firms, custodians, nominees, fiduciaries, and other persons holding our shares in their names, or in the names of nominees, at approved rates for their reasonable expenses in forwarding proxy materials to beneficial owners of securities held of record by them and obtaining their proxies.

All interested parties, including stockholders, may communicate with the Company or our Board by letter addressed to Eterna Therapeutics Inc., Attention: Secretary, 1035 Cambridge Street, Suite 18A, Cambridge, Massachusetts 02141 or by e-mail to Andrew.Jackson@eternatx.com or Sandra.Gurrola@eternatx.com.

Submission of Shareholder Proposals and Director Nominations for 2023 Annual Meeting. Pursuant to Rule 14a-8 under the Securities Exchange Act of 1934, as amended (the “Exchange Act”), our stockholders may present proper proposals for inclusion in our proxy statement and form of proxy and for consideration at the next annual meeting by submitting their proposals to us in a timely manner. Any stockholder of the Company who wishes to present a proposal for inclusion in the proxy statement and form of proxy for action at the 2024 annual meeting of stockholders (the “2024 Annual Meeting”) must comply with our Bylaws and the rules and regulations of the SEC, each as then in effect. Such proposals must be mailed to us at our offices at Eterna Therapeutics Inc., Attention: Secretary, 10355 Cambridge Street, Suite 18A, Cambridge, MA 02141. Under the rules of the SEC, any stockholder proposal intended to be presented at the 2024 Annual Meeting must be received no later than January 3, 2024 in order to be considered for inclusion in our proxy statement and form of proxy relating to such meeting. Under the rules of the SEC, in the event we change the date of our 2024 Annual Meeting by more than thirty days from the one-year anniversary of the Annual Meeting, the deadline for a stockholder proposal to be included in our proxy statement and form of proxy relating to our 2024 Annual Meeting is a reasonable time before we begin to print and send our proxy materials for such meeting. Under our Bylaws, a stockholder must follow certain procedures to nominate persons for election as directors or to introduce an item of business at an annual meeting of stockholders. In order to be timely, we must receive notice of your intention to introduce a nomination or propose an item of business at our 2024 Annual Meeting between the close of business on January 3, 2024 and close of business on February 2, 2024. If we change the date of our 2024 Annual Meeting by more than thirty days before, or more than thirty days after, the one-year anniversary of the Annual Meeting, then the written notice of a stockholder proposal that is not intended to be included in our proxy statement must be delivered, or mailed and received, not later than the ninetieth day prior to our 2024 Annual Meeting or, if later, the tenth day following the day on which public announcement of the date of such meeting is first made. You are advised to review our Bylaws, which contain additional requirements with respect to advance notice of shareholder proposals and director nominees

In addition, for stockholder nominees for directors to be considered timely for inclusion on a universal proxy card pursuant to Rule 14a-19 under the Exchange Act, stockholders must provide notice to us no later than April 17, 2024, containing the information required by Rule 14a-19 under the Exchange Act.

If a stockholder notifies us of an intent to present a proposal at the 2024 Annual Meeting at any time after March 18, 2024 (and for any reason the proposal is voted on at that meeting), it will be considered untimely and our proxy holders will have the right to exercise discretionary voting authority with respect to the proposal, if presented at the meeting, without including information regarding the proposal in our proxy materials. Under the rules of the SEC, in the event we change the date of our 2024 Annual Meeting by more than thirty days after the one-year anniversary of the Annual Meeting, the deadline for a stockholder to submit a proposal for the 2024 Annual Meeting is a reasonable time before we begin to print and send our proxy materials.

The Board knows of no other business to be brought before the Annual Meeting. If, however, any other business should properly come before the Annual Meeting, the persons named as proxies will vote in their discretion as they may deem appropriate.
