Why did I receive a Notice in the mail regarding the availability of proxy materials on the internet?

We are pleased to take advantage of rules of the Securities and Exchange Commission (the “SEC”) that allow companies to furnish their proxy materials over the internet. We intend to first mail a Notice of Internet Availability of Proxy Materials (the “Notice”) and make this proxy statement and the form of proxy available to stockholders on or about , 2026. To those that we do not send a Notice, we will send a full set of proxy materials, which include this proxy statement and an annual report to stockholders, on or about the same date. All stockholders will have the ability to access the proxy materials on the website referred to in the Notice or request to receive a printed set of the proxy materials. Instructions on how to access the proxy materials over the internet or to request a printed copy may be found in the Notice. In addition, stockholders may request to receive proxy materials in printed form or electronically by email on an ongoing basis. A stockholder’s election to receive proxy materials by mail or email will remain in effect until the stockholder terminates it.

Will I receive any other proxy materials by mail?

If we send you a Notice, we may (but are not required to) send you a proxy card, along with a second Notice, on or after , 2026.

How do I attend the Annual Meeting?

The Annual Meeting will be held on Thursday, June 25, 2026, at 9:30 a.m. Eastern time. Information on how to vote at the Annual Meeting is discussed below. We will be hosting the Annual Meeting live via the Internet. You will not be able to attend the Annual Meeting in person.

The Annual Meeting webcast will begin promptly at 9:30 a.m. Eastern time. We expect online check-in to begin at 9:15 a.m. Eastern time, and you should allow ample time for the check-in procedures. We designed the format of the Annual Meeting to ensure that our stockholders who attend the Annual Meeting virtually will be afforded the same rights and opportunities to participate as they would at an in-person meeting.

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.

Who can vote at the Annual Meeting?

Only stockholders of record at the close of business on April 27, 2026, will be entitled to vote at the Annual Meeting. On this record date, there were shares of common stock outstanding and entitled to vote.

Stockholder of Record: Shares Registered in Your Name

If on April 27, 2026, your shares were registered directly in your name with SCYNEXIS’s transfer agent, Equiniti Trust Company, LLC, then you are a stockholder of record. Whether or not you plan to attend the meeting, we urge you to fill out and return your proxy card or vote by proxy over the telephone or on the internet as instructed in the Notice of Internet Access and Availability or below to ensure your vote is counted.

Beneficial Owner: Shares Registered in the Name of a Broker or Bank

If on April 27, 2026, your shares were held, not in your name, but rather in an account at a brokerage firm, bank, dealer, or other similar organization, then you are the beneficial owner of shares held in “street name” and the proxy materials are being sent to you by that organization. The organization holding your account is considered to be the stockholder of record for purposes of voting at the Annual Meeting. As a beneficial owner, you have the right to direct your broker or other agent regarding how to vote the shares in your account, as provided in your voting instruction form. You are also invited to attend the Annual Meeting. Many stockholders of record will provide you with a 16-digit control number via email or in your voting instruction form in order to attend and vote your shares at the Annual Meeting. If you wish to vote your shares at the Annual Meeting, please contact your broker, bank, or other agent for instructions on how to vote your shares.

What am I voting on?

There are six matters scheduled for a vote:

•	Election of our Board of Directors’ six nominees as directors to serve until the 2027 annual meeting of stockholders and until their successors are duly elected and qualified;

•	Ratification of the selection by the Audit Committee of the Board of Directors of Deloitte & Touche LLP as the independent registered public accounting firm of SCYNEXIS, Inc. for its fiscal year ending December 31, 2026;

•	Advisory approval of the compensation of our named executive officers as disclosed in this proxy statement;

•	Advisory approval of the frequency of advisory votes on the compensation of our named executive officers as disclosed in this proxy statement;

•	Approval of an amendment to the 2024 Plan to, among other things, increase the aggregate number of shares of common stock authorized for issuance under the 2024 Plan by 9,600,000 shares; and

•

Approval of an amendment to our Amended and Restated Certificate of Incorporation to increase the total number of authorized shares of common stock to either (i) 60,000,000, subject to approval by our stockholders of a reverse stock split and our implementation of a reverse stock split described in the proxy statement for our special meeting of stockholders to be held on May 19, 2026, or (ii) 300,000,000.

What if another matter is properly brought before the Annual Meeting?

The Board of Directors knows of no other matters that will be presented for consideration at the Annual Meeting. If any other matters are properly brought before the Annual Meeting, it is the intention of the persons named in the Notice of Internet Access and Availability or the proxy card to vote on those matters in accordance with their best judgment.

TABLE OF CONTENTS

How do I vote?

You may either vote “For” all the nominees to the Board of Directors or you may “Withhold” your vote for any nominee you specify. For the other matters to be voted on, you may vote “For” or “Against” or abstain from voting. The procedures for voting are as follows:

Stockholder of Record: Shares Registered in Your Name

If you are a stockholder of record, you may vote your shares at the Annual Meeting. If you do not wish to vote your shares at the Annual Meeting or you will not be attending the Annual Meeting, you may vote by proxy, by telephone or over the internet. To vote by proxy on the internet, go to www.proxyvote.com to complete an electronic proxy card. To vote by proxy by telephone, dial 1-800-690-6903, the toll-free number shown on the proxy card, and follow the recorded instructions. Alternatively, you may complete, sign, and return the proxy card you may have received using the envelope provided with the proxy card. If you vote by proxy over the phone or the internet, you will be asked to provide the control number from the Notice of Internet Access and Availability or proxy card. If you vote by proxy, your vote must be received by 11:59 p.m. Eastern Time on June 24, 2026, to be counted.

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

Beneficial Owner: Shares Registered in the Name of Broker, Bank or other Agent

If you are a beneficial owner of shares held in street name, you should have received a voting instruction form from the broker, bank or other nominee that is the record owner of your shares rather than from us. Simply complete and mail the voting instruction form to ensure that your vote is counted. Alternatively, if your broker provides telephone or internet voting, you may vote by telephone or over the internet as instructed by your broker or bank. To vote at the Annual Meeting, follow the instructions from your broker, bank or other agent included with these proxy materials, or contact that organization for instructions on how to vote your shares. If you wish to vote your shares at the Annual Meeting, please contact your broker, bank or other agent for instructions on how to vote your shares.

How many votes do I have?

On each matter to be voted upon, you have one vote for each share of common stock you own as of April 27, 2026.

What happens if I do not vote?

Stockholder of Record; Shares Registered in Your Name

If you are a stockholder of record and do not vote by completing your proxy card, over the internet or in person at the annual meeting, your shares will not be voted.

Beneficial Owner; Shares Registered in the Name of a Broker or Bank

If you are a beneficial owner and do not instruct your broker, bank, or other agent how to vote your shares, the question of whether your broker or nominee will still be able to vote your shares depends on whether the New York Stock Exchange (“NYSE”) deems the particular proposal to be a “routine” matter. Brokers and nominees can use their discretion to vote “uninstructed” shares with respect to matters that are considered to be “routine,” but not with respect to “non-routine” matters. Under the rules and interpretations of the NYSE, “non-routine” matters are matters that may substantially affect the rights or privileges of stockholders, such as mergers, stockholder proposals, elections of directors (even if not contested), executive compensation (including any advisory stockholder votes on executive compensation and on the frequency of stockholder votes on executive compensation), and certain corporate governance proposals, even if management supported. Accordingly, your broker or nominee may not vote your shares on Proposals 1, 3, 4, 5 and 6 without your instructions but may vote your shares on Proposal 2.

What if I return a proxy card or otherwise vote but do not make specific choices?

If you return a signed and dated proxy card or otherwise vote without marking voting selections, your shares will be voted in accordance with the recommendations of our Board of Directors: “For” the election of all our six nominees for director; “For” the ratification of the Audit Committee’s selection of Deloitte & Touche LLP as the

TABLE OF CONTENTS

independent registered public accounting firm of SCYNEXIS for its fiscal year ending December 31, 2026; “For” the advisory approval of the compensation of our named executive officers as disclosed in this proxy statement; “One Year” for the advisory approval on the frequency of future stockholder votes on the compensation of our named executive officers; “For” the approval of an amendment to the 2024 Plan to, among other things, increase the aggregate number of shares of common stock authorized for issuance under the 2024 Plan by 9,600,000 shares; and “For” the approval of an amendment to our Amended and Restated Certificate of Incorporation to increase the total number of authorized shares of common stock.

If any other matter is properly presented at the Annual Meeting, your proxy holder (one of the individuals named on your proxy card) will vote your shares using his or her best judgment, if permitted under SEC rules.

Who is paying for this proxy solicitation?

We will pay for the entire cost of soliciting proxies. In addition to these proxy materials, our directors and employees may also solicit proxies in person, by telephone, or by other means of communication. Directors and employees will not be paid any additional compensation for soliciting proxies. We may also reimburse brokerage firms, banks and other agents for the cost of forwarding proxy materials to beneficial owners. In addition, we have retained Sodali & Co, 333 Ludlow Street, 5 Floor, South Tower, Stamford, CT 06902, to aid in the solicitation of proxies for a fee of $14,000, plus reasonable out-of-pocket expenses.

What does it mean if I receive more than one set of proxy materials?

If you receive more than one set of proxy materials, your shares may be registered in more than one name or in different accounts. Please follow the voting instructions on the Notice of Internet Access and Availability or proxy cards in the proxy materials to ensure that all of your shares are voted.

Can I change my vote or revoke my proxy after submitting my proxy?

Stockholder of Record; Shares Registered in Your Name

Yes. You can change your vote or revoke your proxy at any time before the final vote at the Annual Meeting. If you are the record holder of your shares, you may change your vote or revoke your proxy in any one of the following ways:

•	You may submit another properly completed proxy card with a later date.

•	You may vote again by telephone or over the internet.

•	You may send a timely written notice that you are revoking your proxy to our Corporate Secretary at SCYNEXIS, Inc., 1 Evertrust Plaza, 13^th Floor, Jersey City, New Jersey 07302.

•	You may attend the Annual Meeting and vote at the Annual Meeting. Simply attending the Annual Meeting will not, by itself, revoke your proxy.

Your most current proxy card or telephone or internet proxy is the one that is counted.

Beneficial Owner; Shares Registered in the Name of a Broker or Bank

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

When are stockholder proposals due for next year’s annual meeting?

To be considered for inclusion in next year’s proxy materials, your proposal must be submitted in writing by , to our Corporate Secretary at SCYNEXIS, Inc., 1 Evertrust Plaza, 13^th Floor, Jersey City, New Jersey, 07302; provided, however, that if our 2027 annual meeting of stockholders is held before May 26, 2027, or after July 25, 2027, then your deadline is a reasonable amount of time prior to the date we begin to print and mail our proxy statement for the 2027 annual meeting of stockholders. If you wish to submit a proposal that is not to be included in next year’s proxy materials or nominate a director pursuant to our Bylaws, you must provide specified information in writing to our Corporate Secretary at the address above by not later than March 27, 2027, nor earlier than the close of business on February 25, 2027, except that if our 2027 annual meeting of stockholders is held before May 26, 2027, or after July 25, 2027, notice to be timely must be so delivered not earlier than the close of

TABLE OF CONTENTS

business on the one hundred twentieth (120^th) day prior to such annual meeting and not later than the close of business on the later of the ninetieth (90^th) day prior to such annual meeting or the tenth (10^th) day following the day on which public announcement of the date of such meeting is first made. You are also advised to review our Bylaws, which contain a description of the information required to be submitted as well as additional requirements about advance notice of stockholder proposals and director nominations.

In addition, stockholders who intend to solicit proxies in support of director nominees other than our nominees must provide their notice any additional information required by Rule 14a-19(b) under the Exchange Act.

Please refer to our bylaws and Rule 14a-19 under the Exchange Act for additional information and requirements regarding stockholder proposals and director nominations. We will not consider any proposal or nomination that is not timely or otherwise does not meet our bylaws and the SEC’s requirements for submitting a proposal or nomination, as applicable. We reserve the right to reject, rule out of order or take other appropriate action with respect to any proposal or nomination that does not comply with these and any other applicable requirements.

How are votes counted?

Votes will be counted by the inspector of election appointed for the Annual Meeting, who will separately count: with respect to the proposal to elect directors, votes “For,” “Withhold” and broker non-votes; with respect to other proposals other than Proposal 4 (advisory approval of the frequency of advisory votes on the compensation of our named executive officers), votes “For,” “Against,” abstentions and, if applicable, broker non-votes; and with respect to Proposal 4, “One Year”, “Two Years”, “Three Years”, abstentions and broker non-votes. The effect of abstentions and broker non-votes, if any, on whether a proposal is approved is set forth under “How many votes are needed to approve each proposal?” below.

What are “broker non-votes”?

As discussed above, when a beneficial owner of shares held in “street name” does not give instructions to the broker or nominee holding the shares as to how to vote on matters deemed by the NYSE to be “non-routine,” the broker or nominee cannot vote the shares. These unvoted shares are counted as “broker non-votes.”

How many votes are needed to approve each proposal?

What is the quorum requirement?

A quorum of stockholders is necessary to hold a valid meeting. A quorum will be present if stockholders holding at least a majority of the outstanding shares entitled to vote are present via webcast at the Annual Meeting or represented by proxy. On the record date, there were shares outstanding and entitled to vote. Thus the holders of shares must attend or represented by proxy at the Annual Meeting to have a quorum.

Your shares will be counted towards the quorum only if you submit a valid proxy (or one is submitted on your behalf by your broker, bank or other nominee) or if you attend the Annual Meeting. Abstentions and broker non-votes will be counted towards the quorum requirement. If there is no quorum, the chairman of the Annual Meeting or the holders of a majority of the shares present via webcast at the Annual Meeting or represented by proxy may adjourn the Annual Meeting to another date.

How can I find out the results of the voting at the Annual Meeting?

We expect to announce the preliminary voting results at the Annual Meeting. In addition, final voting results will be published in a current report on Form 8-K that we expect to file with the SEC within four business days after the Annual Meeting. If final voting results are not available to us in time to file a Form 8-K within four business days after the Annual Meeting, we intend to file a Form 8-K to publish preliminary results and, within four business days after the final results are known to us, file an amendment to the Form 8-K to publish the final results.

What proxy materials are available on the internet?

The proxy statement and annual report to stockholders are available at www.proxyvote.com.

Who should I contact if I have questions about voting my shares or need assistance in voting?

PROPOSAL 1

ELECTION OF DIRECTORS

SCYNEXIS’s Board of Directors (the “Board”) is elected annually at each annual meeting. Vacancies on the Board may be filled only by persons elected by a majority of the remaining directors. A director elected by the Board to fill a vacancy shall serve for the remainder of the year, and until the director’s successor is duly elected and qualified. This includes vacancies created by an increase in the number of directors.

The Board currently has seven members, all of whose terms of office expire at the Annual Meeting. Our Nominating and Corporate Governance Committee recommended, and our Board approved, the nomination of six nominees for election at the Annual Meeting. Proxies may not be voted for a greater number of persons than the number of nominees named. All of our nominees were elected by our stockholders at our 2025 annual meeting of stockholders. On April 16, 2026, Steven C. Gilman notified the Board of his intent to retire as a member of the Board and therefore not stand for reelection at the Annual Meeting. Accordingly, Dr. Gilman’s term as a director will end when his current term expires at the Annual Meeting. The size of our Board of Directors will be reduced to six directors effective at the conclusion of the Annual Meeting.

Our six nominees, their ages as of April 15, 2026, and their position currently held with SCYNEXIS, are as follows:


Name	Age	Position Held With SCYNEXIS
Armando Anido	68	Director
David Angulo, M.D.	61	Chief Executive Officer, President and Director
Ann F. Hanham, Ph.D.	73	Director
David Hastings	64	Director
Guy Macdonald	67	Chairman of the Board, Director
Philippe Tinmouth	62	Director

If elected at the Annual Meeting, each of these nominees would be elected and qualified to serve until the 2027 annual meeting of stockholders and until his or her successor is duly elected and qualified, or, if sooner, until the director’s death, resignation or removal. It is our policy to encourage directors and nominees for director to attend the Annual Meeting. All of our current directors attended the 2025 annual meeting of stockholders.

If any nominee becomes unavailable for election as a result of an unexpected occurrence, your shares will be voted for the election of a substitute nominee proposed by us. Each person nominated for election has agreed to serve if elected. Our management has no reason to believe that any nominee will be unable to serve.

This Proposal 1 is to elect our six nominees nominated as directors. The biographies of each of the nominees below contain information regarding the person’s service as a director, business experience, director positions held currently or at any time during the last five years, information regarding involvement in certain legal or administrative proceedings, if applicable, and the experiences, qualifications, attributes and skills of each director, including those that led to the Nominating and Corporate Governance Committee and the Board’s conclusion that the director should continue to serve as a director of SCYNEXIS.

Armando Anido joined our Board on January 21, 2019. Mr. Anido served as Chairman of the board of directors and Chief Executive Officer of Zynerba Pharmaceuticals, a publicly-traded biopharmaceutical company, from October 2014 until it was acquired by Harmony Biosciences Holdings, Inc.

Prior to Zynerba, Mr. Anido served as CEO of two publicly-traded companies. Most recently, he was the CEO and a director of NuPathe Inc., a publicly-traded pharmaceutical company, which was acquired by Teva Pharmaceuticals in February 2014. At NuPathe, he led the company through FDA approval of its lead product, Zecuity®, the first transdermal patch for migraine, to pre-launch before the company’s acquisition by Teva. Prior to NuPathe he served as President, CEO and a director of Auxilium Pharmaceuticals, a specialty pharmaceutical company acquired by Endo Pharmaceuticals, Inc. in January 2015.

Mr. Anido earned a BS in Pharmacy and an MBA from West Virginia University. Because of Mr. Anido’s extensive executive, operational, and commercial leadership in the biopharmaceutical industry, we believe he is able to make valuable contributions to our Board of Directors.

David Angulo, M.D., has served as a member of our Board and as our Chief Executive Officer since January 2023. Dr. Angulo joined SCYNEXIS in 2015 as Chief Medical Officer. An infectious disease specialist with more than 20 years of experience in successful drug development, he previously served as Vice President, Research and Development of Brickell Biotech, Inc.

He received his medical degree from the Universidad de Guadalajara, Mexico, and has post-graduate degrees in pediatrics and infectious diseases. Because of Dr. Angulo’s extensive experience in drug development, as well as role as our Chief Executive Officer and his long tenure with, and extensive knowledge of, our company and our product candidates, we believe he is able to make valuable contributions to our Board.

Ann F. Hanham, Ph.D., has served as a member of our Board since December 2008. Prior to becoming a Founding Partner and Managing Director of BAR Capital Management, a privately-held life-sciences venture capital fund, in December 2013, she was a General Partner with Burrill & Company, a life sciences venture capital firm from 2000 to 2013.

Dr. Hanham holds a Ph.D. from the University of British Columbia, an MSc from Simon Fraser University, and a BSc from the University of Toronto. She was also Board Certified in Toxicology in 1986. Because of Dr. Hanham’s extensive clinical and regulatory experience, as well as her extensive experience in working with development stage biotechnology companies, we believe she is able to make valuable contributions to our Board.

David Hastings joined our Board on September 24, 2015. Mr. Hastings has served as Chief Financial Officer of Trevi Therapeutics, Inc. (Nasdaq: TRVI), a publicly-traded biopharmaceutical company, since January 2026. Prior to Trevi, Mr. Hastings served as the Chief Financial Officer at Arbutus Biopharma Corp.

Mr. Hastings previously served on the boards of directors of VBL Therapeutics (Nasdaq: VBLT) and Entasis Therapeutics Inc. Mr. Hastings received his B.A. in Economics at the University of Vermont. Because of Mr. Hastings extensive financial experience, including an executive position as chief financial officer of multiple Nasdaq-listed companies as well as his relationships with institutional investors and investment banks, we believe he is able to make valuable contributions to our Board.

Guy Macdonald has served as a member of our Board since November 2014. Mr. Macdonald served as a member of the board of directors of Tetraphase Pharmaceuticals, Inc., a publicly-traded biopharmaceutical company, from January 2008 to July 2020, in addition to serving as its President and Chief Executive Officer from January 2008 to August 2019.

TABLE OF CONTENTS

Hospital Products. Mr. Macdonald received an Honors Degree in biochemistry from Dundee University in Dundee, Scotland. Because of Mr. Macdonald’s extensive experience in drug development and commercialization, particularly with anti-infectives, including antifungals, we believe he is able to make valuable contributions to our Board.

Philippe Tinmouth joined our Board on December 13, 2019. Mr. Tinmouth has been a Partner at Flagship Pioneering since September 2025. Prior to Flagship, Mr. Tinmouth served as a Senior Advisor to Mammoth Biosciences, Inc., a biotechnology company, from March 2025 through December 2025 and previously served as Chief Business and Strategy Officer from December 2022 through February 2025.

From October 2002 through his retirement in March 2020, Mr. Tinmouth served in various positions at Vertex Pharmaceuticals (Nasdaq: VRTX), a publicly traded biopharmaceutical company, most recently serving as Vice President and Head of Business Development & Alliance Management since July 2013. From 1997 to 2002, Mr. Tinmouth held various positions at Bain & Company, most recently serving as a Senior Manager in the Boston office, where he advised both Fortune 50 pharmaceutical companies and smaller biotechnology companies on growth strategies.

Mr. Tinmouth holds a Master’s Degree in Business Administration from Harvard Business School and a Bachelor’s Degree with Honors in Mechanical Engineering from Queen’s University in Canada. Because of Mr. Tinmouth’s extensive business development, alliance management, and strategic leadership in the biopharmaceutical industry, we believe he is able to make valuable contributions to our Board.

In the last ten years none of our directors were executive officers of a corporation that declared bankruptcy within two years of the director being an executive officer of that corporation other than Mr. Hastings, who was an executive officer of Unilife Corporation when it filed for voluntary bankruptcy in April 2017. There are no family relationships among our directors and executive officers.

Diversity of our Board of Directors

As of our record date, 43% of our directors were women or racially or ethnically diverse individuals. We believe that our current directors possess diverse professional experiences, skills, and backgrounds in addition to, among other characteristics, high standards of personal and professional ethics and valuable knowledge of our business and our industry.

TABLE OF CONTENTS

Independence of The Board

As required under the Nasdaq Stock Market (“Nasdaq”) listing standards, a majority of the members of our Board must qualify as “independent,” as affirmatively determined by our Board. The Board consults with SCYNEXIS’s counsel to ensure that the Board’s determinations are consistent with all relevant securities laws and other laws and regulations regarding the definition of “independent,” including those set forth in pertinent listing standards of Nasdaq, as in effect from time to time.

Consistent with these considerations, after review of all relevant identified transactions or relationships between each director, or any of their family members, and SCYNEXIS, its senior management and its independent registered public accounting firm, the Board affirmatively has determined that all of the directors during 2025 and currently, other than Dr. Angulo, our president and chief executive officer, are independent directors within the meaning of the applicable Nasdaq listing standards. In making this determination, the Board found that none of the directors or nominees for director other than Dr. Angulo had a material or other disqualifying relationship with SCYNEXIS.

Information Regarding the Board and Its Committees

The Board has an Audit Committee, a Compensation Committee, and a Nominating and Corporate Governance Committee. The following table provides membership information and meeting information for 2025 for each of the Audit, Compensation, and Nominating and Corporate Governance Committees:


Name	Audit	Compensation	Nominating and Corporate Governance

Total meetings in year 2025	4	3	1

*	Chair of the committee.

Below is a description of each committee of the Board. Each of the committees has authority to engage legal counsel or other experts or consultants, as it deems appropriate to carry out its responsibilities. The Board has determined that each member of each committee meets the applicable rules and regulations regarding “independence” and that each member is free of any relationship that would interfere with his individual exercise of independent judgment with regard to SCYNEXIS. Each of these committees has a charter, and the charters for each of these committees are available on our website at www.scynexis.com.

Audit Committee

Our Audit Committee currently consists of Ann F. Hanham, Ph.D., David Hastings, and Philippe Tinmouth, each of whom satisfies the independence requirements under the Nasdaq Global Market listing standards and Rule 10A-3(b)(1) of the Securities Exchange Act of 1934, or the Exchange Act. Our Board has determined that Mr. Hastings is an “audit committee financial expert” within the meaning of SEC regulations.

Mr. Hastings is the Chair of the Audit Committee. Each member of our Audit Committee can read and understand fundamental financial statements in accordance with Audit Committee requirements. In arriving at this determination, our Board has examined each Audit Committee member’s scope of experience and the nature of their employment in the corporate finance sector.

Our Audit Committee oversees our corporate accounting and financial reporting process. The Audit Committee has the following responsibilities, among other things, as set forth in the Audit Committee charter:

•	reviewing and pre-approving the engagement of our independent registered public accounting firm to perform audit services and any permissible non-audit services;

•	evaluating the performance of our independent registered public accounting firm and deciding whether to retain their services;

TABLE OF CONTENTS

•

reviewing our annual and quarterly financial statements and reports and discussing the statements and reports with our independent registered public accounting firm and management, including a review of disclosures under the section of our annual report on Form 10-K as filed March 4, 2026, titled “Management’s Discussion and Analysis of Financial Condition and Results of Operations;”

•	considering and approving or disapproving of all related party transactions;

•	preparing the Audit Committee report required by the SEC to be included in our annual proxy statement;

•	reviewing, with our independent registered public accounting firm and management, significant issues that may arise regarding accounting principles and financial statement presentation, as well as matters concerning the scope, adequacy and effectiveness of our financial controls;

•	conducting an annual assessment of the performance of the Audit Committee and its members, and the adequacy of its charter; and

•	establishing procedures for the receipt, retention and treatment of complaints received by us regarding financial controls, accounting or auditing matters.

Compensation Committee

Our Compensation Committee currently consists of Armando Anido, Steven C. Gilman, Ph.D., and Guy Macdonald, each of whom our Board has determined to be independent under the Nasdaq Global Market listing standards. Dr. Gilman will not be standing for re-appointment at the Annual Meeting and will retire from the board and each of the committees at the expiration of his current term as a director, as of the date of the Annual Meeting.

Our Compensation Committee reviews and recommends policies relating to compensation and benefits of our officers and employees. The Compensation Committee has the following responsibilities, among other things, as set forth in the Compensation Committee’s charter:

•

recommending to the full Board the compensation and other terms of employment of our chief executive officer, determining the compensation and other terms of employment of our other executive officers, and reviewing and recommending to the full Board corporate performance goals and objectives relevant to the compensation of executive officers;

•	reviewing and recommending to the full Board the compensation of our non-employee directors;

•	evaluating, adopting and administering the equity incentive plans, compensation plans, and similar programs advisable for us, as well as modification or termination of existing plans and programs;

•	establishing policies with respect to equity compensation arrangements;

•	reviewing and discussing annually with management our “Compensation Discussion and Analysis” if required by SEC rules;

•	preparing the Compensation Committee report if required by the SEC to be included in our annual proxy statement; and

•	reviewing and evaluating, at least annually, the performance of the Compensation Committee and the adequacy of its charter.

Compensation Committee Processes and Procedures

We expect that the Compensation Committee will generally meet four times annually and with greater frequency if necessary. The agenda for each meeting is usually developed by the Chair of the Compensation Committee, in consultation with the Chief Executive Officer. The Compensation Committee meets regularly in executive session. However, from time to time, various members of management and other employees as well as outside advisors or consultants may be invited by the Compensation Committee to make presentations, to provide financial or other background information or advice or to otherwise participate in Compensation Committee meetings. The Chief Executive Officer may not participate in, or be present during, any deliberations or determinations of the Compensation Committee regarding his compensation or individual performance objectives. The charter of the Compensation Committee grants the Compensation Committee full access to all books, records, facilities and personnel of SCYNEXIS, and provides that the Compensation Committee may form and delegate

TABLE OF CONTENTS

authority to subcommittees as appropriate. In addition, under the charter, the Compensation Committee has the authority to obtain, at the expense of SCYNEXIS, advice and assistance from internal and external legal, accounting or other advisors and other external resources that the Compensation Committee considers necessary or appropriate in the performance of its duties. The Compensation Committee has direct responsibility for the oversight of the work of any advisers engaged for the purpose of advising the Committee. In particular, the Compensation Committee has the sole authority to retain compensation consultants to assist in its evaluation of executive and director compensation, including the authority to approve the consultant’s reasonable fees and other retention terms. Under the charter, the Compensation Committee may select, or receive advice from, a compensation consultant, legal counsel or other adviser to the Compensation Committee, other than in-house legal counsel and certain other types of advisers, only after taking into consideration six factors, prescribed by the SEC and Nasdaq, that bear upon the adviser’s independence; however, there is no requirement that any adviser be independent.

During the past fiscal year, after taking into consideration the six factors prescribed by the SEC and Nasdaq, the Compensation Committee engaged Pearl Meyer as an independent compensation consultant. Pearl Meyer serves as a compensation resource available to the Compensation Committee on an hourly basis. As part of its engagement, Pearl Meyer was requested by the Compensation Committee to develop a grant value method for equity compensation of employees and directors for consideration by the Compensation Committee and to review the competitiveness of director compensation based on a comparative group of biotechnology and pharmaceutical companies. Pearl Meyer was also requested by the Compensation Committee to review compensation of senior executives in comparison with other biotech companies to advise the Compensation Committee on compensation benchmarking, to review equity guideline recommendations and to assist in developing an overall employee compensation structure for consideration by the Compensation Committee.

Nominating and Corporate Governance Committee

Our Nominating and Corporate Governance Committee currently consists of Armando Anido, Steven C. Gilman, Ph.D., and Ann F. Hanham, Ph.D., each of whom our Board has determined to be independent under the Nasdaq Global Market listing standards. Dr. Gilman will not be standing for re-appointment at the Annual Meeting and will retire from the board and each of the committees at the expiration of his current term as a director, as of the date of the Annual Meeting.

Our Nominating and Corporate Governance Committee makes recommendations regarding corporate governance, the composition of our Board, identification, evaluation and nomination of director candidates and the structure and composition of committees of our Board. The Nominating and Corporate Governance Committee has the following responsibilities, among other things, as set forth in the Nominating and Corporate Governance Committee’s charter:

•	reviewing periodically and evaluating director performance on our Board and its applicable committees, and recommending to our Board and management areas for improvement;

•	interviewing, evaluating, nominating and recommending individuals for membership on our Board;

•	reviewing and recommending to our Board any amendments to our corporate governance policies; and

•	reviewing and assessing, at least annually, the performance of the Nominating and Corporate Governance Committee and the adequacy of its charter.

In considering whether to recommend any candidates for inclusion in the Board’s slate of recommended director nominees, including candidates recommended by stockholders, the Nominating and Corporate Governance Committee considers the candidate’s ability to read and understand financial statements, age, personal integrity and ethics, relevant expertise upon which to be able to offer advice and guidance to management, having sufficient time to devote to the affairs of the company, demonstrated experience in his or her field, ability to exercise sound business judgment, and having the commitment to rigorously represent the long-term interests of the company’s stockholders. In addition, when conducting its assessment, the Nominating and Corporate Governance Committee considers any criteria for director qualifications set by the Board, as well as diversity, skills, and such other factors as it deems appropriate given the current needs of the Board and the company to maintain a balance of knowledge, experience and capability. When considering diversity, the Board and Nominating and Corporate Governance Committee views “diversity” as diversity of experience and expertise. The Board and Nominating and Corporate Governance Committee believe that having a Board diverse in experience and expertise enables the Board, as a body, to have the broad range of requisite expertise and experience to guide the company and management and to

TABLE OF CONTENTS

fulfill its role of oversight and stewardship. However, neither the Board nor the Nominating and Corporate Governance Committee has developed a policy with respect to diversity in identifying nominees for director, other than to consider diversity when assessing nominees.

In the case of incumbent directors whose terms of office are set to expire, the Nominating and Corporate Governance Committee reviews such directors’ overall service to the company during their term, including the number of meetings attended, level of participation, quality of performance, and any other relationships and transactions that might impair such directors’ independence. In the case of new director candidates, the Nominating and Corporate Governance Committee also determines whether the nominee should be independent for Nasdaq purposes, which determination is based upon applicable Nasdaq listing standards, applicable SEC rules and regulations and the advice of counsel, if necessary. The Nominating and Corporate Governance Committee does not assign specific weights to particular criteria and no particular criterion is necessarily applicable to all prospective nominees. The Nominating and Corporate Governance Committee then uses its network of contacts to compile a list of potential candidates, but may also engage, if it deems appropriate, a professional search firm. The Nominating and Corporate Governance Committee has engaged a professional search firm several times and that firm has performed a recruiting function by compiling lists of potential candidates, evaluating and interviewing the most appropriate candidates, and presenting to the Nominating and Corporate Governance Committee the most qualified. The Nominating and Corporate Governance Committee conducts any appropriate and necessary inquiries into the backgrounds and qualifications of possible candidates after considering the function and needs of the Board. The Nominating and Corporate Governance Committee meets to discuss and consider such candidates’ qualifications and then recommends a nominee to the Board by majority vote.

To date, the Nominating and Corporate Governance Committee has not received a timely recommended director nominee from a stockholder or stockholders holding more than 5% of our voting stock.

The Nominating and Corporate Governance Committee will consider director candidates recommended by stockholders who demonstrate, by written documentation, satisfactory to the Nominating and Corporate Governance Committee, that such stockholders hold outstanding shares of the company. The Nominating and Corporate Governance Committee does not intend to alter the manner in which it evaluates candidates, including the minimum criteria set forth above, based on whether the candidate was recommended by a stockholder or not. Stockholders who wish to recommend individuals for consideration by the Nominating and Corporate Governance Committee to become nominees for election to the Board at an annual meeting may do so by delivering a written recommendation to the Nominating and Corporate Governance Committee at the following address: 1 Evertrust Plaza, 13^th Floor, Jersey City, New Jersey, 07302 no earlier than 120 days before, nor later than 90 days before, the first anniversary of the previous year’s annual meeting. Submissions must include the full name of the proposed nominee, a description of the proposed nominee’s business experience for at least the previous five years, complete biographical information, and a description of the proposed nominee’s qualifications as a director. Any such submission must be accompanied by the written consent of the proposed nominee to be named as a nominee and to serve as a director if elected.

Board Leadership Structure

The Board’s leadership structure is a separate Chairman of the Board and Chief Executive Officer. Mr. Guy Macdonald was appointed as our Chairman in June 2015. The Chairman has authority, among other things, to call and preside over Board meetings, including meetings of the independent directors, to set meeting agendas and to determine materials to be distributed to the Board. Accordingly, the Chairman has substantial ability to shape the work of the Board. The Board believes that separation of the positions of Chairman and Chief Executive Officer reinforces the independence of the Board in its oversight of the business and affairs of SCYNEXIS and is appropriate for SCYNEXIS. In addition, the Board believes that having an independent Chairman creates an environment that is more conducive to objective evaluation and oversight of management’s performance, increasing management accountability and improving the ability of the Board to monitor whether management’s actions are in the best interests of the company and its stockholders. As a result, the Board believes that having an independent Chairman can enhance the effectiveness of the Board as a whole.

Role of the Board in Risk Oversight

The Board has an active role, as a whole and also at the committee level, in overseeing management of the company’s risks. The Board regularly reviews information regarding the company’s credit, liquidity and operations, as well as the risks associated with each. The Audit Committee’s charter mandates the Audit Committee to review

TABLE OF CONTENTS

and discuss with management, and the company’s independent registered public accounting firm, as appropriate, the company’s major financial risk exposures and the steps taken by management to monitor and control these exposures. The Compensation Committee is responsible for overseeing the management of risks relating to the company’s executive compensation plans and arrangements. The Nominating and Corporate Governance Committee manages risks associated with the independence of the Board and potential conflicts of interest. While each committee is responsible for evaluating certain risks and overseeing the management of such risks, the entire Board is regularly informed through committee reports about such risks.

Compensation Policies and Practices as They Relate to Risk Management

With the help of the Compensation Committee’s independent compensation consulting firm, Pearl Meyer, the Compensation Committee has reviewed the company’s compensation policies and practices as they relate to risk management for all employees, including executive officers. Following such review, the Compensation Committee determined that risks arising from the company’s compensation policies and practices for its employees are not reasonably likely to have a material adverse effect on the company.

Meetings of the Board

The Board met four times in 2025. All directors attended at least 75% of the aggregate number of the meetings of the Board and the committees on which they served, held during the portion of the last fiscal year for which they were directors or committee members in 2025.

As required under applicable Nasdaq listing standards, in fiscal year 2025, SCYNEXIS’s independent directors met in regularly scheduled executive sessions at which only independent directors were present.

Stockholder Communications with the Board

SCYNEXIS’s Board has adopted a formal process by which stockholders may communicate with the Board or any of its directors. Stockholders who wish to communicate with the Board may do so by sending written communications addressed as follows: Scott Sukenick, General Counsel, SCYNEXIS, Inc., 1 Evertrust Plaza, 13^th Floor, Jersey City, New Jersey, 07302, or via email to scott.sukenick@scynexis.com. The communications will be reviewed by the General Counsel. The General Counsel will forward such communication to the Board or to any individual director to whom the communication is addressed unless the communication is unduly frivolous, hostile, threatening or similarly inappropriate, in which case, the General Counsel shall discard the communication.

Code of Business Conduct and Ethics

SCYNEXIS has adopted the SCYNEXIS, Inc. Code of Business Conduct and Ethics that applies to all officers, directors and employees. The Code of Business Conduct and Ethics is available on our website, which is www.scynexis.com, and available in print to any stockholder who requests it. Requests for printed copies of the Code of Business Conduct and Ethics can be made by writing to Attn: Corporate Secretary, SCYNEXIS, Inc., 1 Evertrust Plaza, 13^th Floor, Jersey City, New Jersey, 07302. If SCYNEXIS makes any substantive amendments to the Code of Business Conduct and Ethics or grants any waiver from a provision of the Code of Business Conduct and Ethics to any executive officer or director, SCYNEXIS will promptly disclose the nature of the amendment or waiver on its website.

Insider Trading Policy

SCYNEXIS has adopted an Insider Trading Policy that governs the purchase, sale and/or other dispositions of its securities by the directors, officers and employees that is designed to promote compliance with insider trading laws, rules and regulations, as well as procedures designed to further the foregoing purposes. A copy of the Insider Trading Policy is filed as an exhibit to SCYNEXIS’s Annual Report on Form 10-K for the fiscal year ended December 31, 2025. In addition, it is SCYNEXIS’s intent to comply with applicable laws and regulations relating to trading in its securities.

Policy Against Hedging Transactions

SCYNEXIS believes that speculative and short-term trading of its securities is not appropriate for its employees or directors and thus provides, in its insider trading policy, that no employee, director or covered consultant may engage in short sales, transactions in put or call options or other derivative securities based on SCYNEXIS securities, hedging transactions, margin accounts, pledges, or other inherently speculative transactions with respect to SCYNEXIS equity at any time.

PROPOSAL 2

RATIFICATION OF SELECTION OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

The Audit Committee of the Board of Directors has selected Deloitte & Touche LLP as SCYNEXIS’s independent registered public accounting firm for the fiscal year ending December 31, 2026, and has further directed that management submit the selection of its independent registered public accounting firm for ratification by the stockholders at the Annual Meeting. Deloitte & Touche LLP has audited SCYNEXIS’s financial statements since fiscal year 2000. Representatives of Deloitte & Touche LLP are expected to be present at the Annual Meeting. They will have an opportunity to make a statement if they so desire and will be available to respond to appropriate questions.

Neither SCYNEXIS’s Bylaws nor other governing documents or law require stockholder ratification of the selection of Deloitte & Touche LLP as SCYNEXIS’s independent registered public accounting firm. However, the Audit Committee of the Board is submitting the selection of Deloitte & Touche LLP to the stockholders for ratification as a matter of good corporate practice. If the stockholders fail to ratify the selection, the Audit Committee of the Board will reconsider whether or not to retain that firm. Even if the selection is ratified, the Audit Committee of the Board in its discretion may direct the appointment of different independent auditors at any time during the year if they determine that such a change would be in the best interests of SCYNEXIS and its stockholders.

Principal Accountant Fees and Services

The following table represents aggregate fees billed to us for the fiscal years ended December 31, 2025, and December 31, 2024, by Deloitte & Touche LLP, SCYNEXIS’s independent registered public accounting firm (in thousands).


	Fiscal 2025	Fiscal 2024
Audit Fees⁽¹⁾	$888	$859
Audit-Related Fees	—	—
Tax Fees	—	—
All Other Fees	—	—
Total Fees	$888	$859

(1)

Audit fees consist of fees billed for professional services rendered for the audit of our consolidated annual financial statements and review of the interim consolidated financial statements and the issuance of consent and comfort letters in connection with registration statement filings with the Securities and Exchange Commission, and all services that are normally provided by the accounting firm in connection with statutory and regulatory filings or engagements.

All fees described above were approved by the Audit Committee.

Pre-Approval Policy and Procedures

The Audit Committee has adopted a policy and procedures for the pre-approval of audit and non-audit services rendered by our independent registered public accounting firm, Deloitte & Touche LLP. The policy generally pre-approves specified services in the defined categories of audit services, audit-related services and tax services up to specified amounts. Pre-approval may also be given as part of the Audit Committee’s approval of the scope of the engagement of the independent auditor or on an individual, explicit, case-by-case basis before the independent auditor is engaged to provide each service. The pre-approval of services may be delegated to one or more of the Audit Committee’s members, but the decision must be reported to the full Audit Committee at its next scheduled meeting.

The Audit Committee has determined that the rendering of services other than audit services by Deloitte & Touche LLP is compatible with maintaining the principal accountant’s independence.

REPORT OF THE AUDIT COMMITTEE OF THE BOARD^*

Management is responsible for SCYNEXIS’s internal controls and the financial reporting process. The independent registered public accounting firm is responsible for performing an independent audit of SCYNEXIS’s consolidated financial statements in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB) to obtain reasonable assurance that SCYNEXIS’s consolidated financial statements are free from material misstatement and expressing an opinion on the conformity of such financial statements with accounting principles generally accepted in the United States. We are responsible for overseeing and monitoring Deloitte & Touche LLP’s auditing process on behalf of the Board of Directors.

In this context, the Audit Committee has reviewed and discussed the audited consolidated financial statements for the fiscal year ended December 31, 2025, with management and Deloitte & Touche LLP. The Audit Committee has discussed with Deloitte & Touche LLP the matters required to be discussed by the applicable requirements of the PCAOB and the Securities and Exchange Commission. The Audit Committee has also received the written disclosures and the letter from Deloitte & Touche LLP required by applicable requirements of the PCAOB regarding the independent accountants’ communications with the Audit Committee concerning independence, and has discussed with the independent registered public accounting firm the accounting firm’s independence.

Based on its discussions with management and the independent registered public accounting firm, the Audit Committee has recommended to the Board of Directors that the audited consolidated financial statements be included in SCYNEXIS’s Annual Report on Form 10-K for the fiscal year ended December 31, 2025.

PROPOSAL 3

ADVISORY VOTE ON NAMED EXECUTIVE OFFICER COMPENSATION

Under the Dodd-Frank Wall Street Reform and Consumer Protection Act, or the Dodd-Frank Act, and Section 14A of the Exchange Act, SCYNEXIS’s stockholders are entitled to vote to approve, on an advisory basis, the compensation of the named executive officers (those executive officers appearing in the “Summary Compensation Table” below), or “NEOs,” commonly referred to as a “say-on-pay vote,” as disclosed in this proxy statement in accordance with SEC rules.

This vote is not intended to address any specific item of compensation, but rather the overall compensation of SCYNEXIS’s NEOs and the compensation philosophy, policies and practices described in this proxy statement. The compensation of SCYNEXIS’s NEOs subject to the vote is disclosed in the compensation tables and the related narrative disclosure contained in this proxy statement.

Before you vote on this proposal, we urge you to read the executive compensation information (including the compensation tables and the accompanying footnotes and narrative) set forth in this Proxy Statement. As we describe in these disclosures, our compensation philosophy strives to align the interests of our employees and board members with those of our stockholders. As part of this philosophy, we emphasize equity over cash compensation. We seek to ensure that the total compensation paid to our executive officers is reasonable and competitive.

Accordingly, our Board of Directors is asking stockholders to indicate their support for the compensation of SCYNEXIS’s named executive officers by casting a non-binding advisory vote “FOR” the following resolution:

“RESOLVED, that the compensation paid to SCYNEXIS’s named executive officers, as disclosed in the proxy statement pursuant to Item 402 of Regulation S-K, including the compensation tables and narrative discussion, is hereby APPROVED.”

This is an advisory vote and the results will not be binding; however, we, our Board of Directors, and the Compensation Committee value the views of our stockholders and intend to consider the outcome of this vote when making future compensation decisions of our NEOs and on our executive compensation principles, policies, and procedures and will evaluate whether any actions are necessary to address the stockholders’ concerns.

THE BOARD RECOMMENDS

A VOTE IN FAVOR OF PROPOSAL 3.

PROPOSAL 4

ADVISORY VOTE ON THE FREQUENCY OF NAMED EXECUTIVE OFFICER COMPENSATION

ADVISORY VOTES

Under the Dodd-Frank Act and Section 14A of the Exchange Act, every six calendar years stockholders are entitled to vote, on an advisory basis, whether say-on-pay votes should occur every year, every two years or every three years.

Our Board of Directors has determined that holding an advisory vote on executive compensation every “One YEAR” is the most appropriate policy for SCYNEXIS at this time. Holding an annual say-on-pay vote is a meaningful and effective way to gather feedback from stockholders on SCYNEXIS’s compensation principles, policies, and procedures. Accordingly, we are asking stockholders to indicate whether they would prefer an advisory vote every year, every two years or every three years.

The option among the choices of every year, every two years or every three years, that receives the votes of the holders of a majority of shares present in person or represented by proxy and voting on this proposal at the Annual Meeting will be deemed to be the frequency preferred by the stockholders. If no frequency receives votes from a majority of the shares voting on this proposal, no preferred frequency will have been approved by the stockholders.

Our Board of Directors and the Compensation Committee value the views of our stockholders in this matter and intend to hold say-on-pay votes in the future in accordance with the frequency that receives the most stockholder support. However, because this is an advisory vote and the results will not be binding, the Board of Directors may decide that it is in the best interests of the stockholders that SCYNEXIS hold an advisory vote on named executive officer compensation more or less frequently than the option preferred by the stockholders.

THE BOARD RECOMMENDS

A VOTE IN FAVOR OF “ONE YEAR” FOR THIS PROPOSAL 4.

PROPOSAL 5

APPROVAL OF AN AMENDMENT TO THE SCYNEXIS, INC. 2024 EQUITY INCENTIVE PLAN

In April 2026, the Board approved an amendment to the SCYNEXIS, Inc. 2024 Equity Incentive Plan (the “2024 Plan”), subject to stockholder approval of this proposal and an amendment to our Amended and Restated Certificate of Amendment as described in Proposal 6. We refer to the 2024 Equity Incentive Plan, as amended by the Board in April 2026, as the “Amended 2024 Plan” throughout this proxy statement.

The material differences between the 2024 Plan and the Amended 2024 Plan are (i) an increase to the maximum number of shares of our common stock issuable under the 2024 Plan by 9,600,000 shares and (ii) an increase to the maximum number of shares of our common stock issuable through incentive stock options (“ISOs”) granted under the 2024 Plan by 28,800,000 shares.

We are seeking stockholder approval of the Amended 2024 Plan to allow us to continue granting equity awards at levels determined appropriate by our Board or Compensation Committee and thereby enable us to continue to have a competitive equity incentive program to compete with our peer group for key talent.

If this Proposal 5 is approved by our stockholders, the Amended 2024 Plan will become effective as of the date of the Annual Meeting. In the event our stockholders do not approve this Proposal 5, the Amended 2024 Plan will not become effective, and the 2024 Plan will continue in its current form.

This Proposal 5 does not assume any implementation of a reverse stock split. If a reverse stock split is implemented, all of the foregoing numbers would be proportionally adjusted based on the split ratio determined by the Board. Refer to our proxy statement filed on , 2026 with the SEC for our special meeting to be held on May 19, 2026 for more information. Additionally, if a reverse stock split is implemented, outstanding awards under the Amended 2024 Plan would be proportionally adjusted.

Why You Should Vote to Approve the Amended 2024 Plan

Equity Awards Are an Important Part of Our Compensation Philosophy

Our Board believes that our future success depends, in large part, on our talent and that the issuance of equity awards is a key element underlying our ability to attract, retain and motivate key personnel, non-employee directors, consultants, and advisors, and better aligns the interests of our personnel, non-employee directors, consultants, and advisors with those of our stockholders. The Amended 2024 Plan will allow us to continue to provide performance-based incentives to our eligible employees, non-employee directors, consultants, and advisors. Therefore, the Board believes that the Amended 2024 Plan is in our best interests and the best interests of our stockholders and recommends a vote in favor of this Proposal 5.

We Have Experienced and Expect to Continue to Experience Growth in Our Business

The Board believes that the Amended 2024 Plan is necessary to ensure that the number of shares available for issuance is sufficient to allow us to continue to attract and retain the services of talented individuals essential to our long-term growth and financial success. Our Board strongly believes that the issuance of equity awards is a key element underlying our ability to attract, retain and motivate our employees, including our executives, and our consultants and advisors, and is a substantial contributing factor to our success and the growth of our business. So far we have relied significantly on equity incentives in the form of stock option awards and restricted stock unit awards to attract and retain key employees, and we believe that equity incentives are necessary for us to remain competitive in the marketplace for executive talent and other employees.

The Size of Our Share Reserve Request Is Reasonable

If the Amended 2024 Plan is approved by our stockholders, we will have 11,908,196 shares available for grant after this annual meeting (based on shares available as of April 1, 2026), which we anticipate being sufficient for grants for the next one to two years, and necessary to provide a predictable amount of equity for attracting, retaining, and motivating employees. The size of our request is also reasonable in light of our historical burn rate, which has aligned with biotech market norms.

We Manage Our Equity Incentive Award Use Carefully, and Dilution Is Reasonable

We continue to believe that equity awards such as stock options and restricted stock units are a vital part of our overall compensation program. Our compensation philosophy reflects broad-based eligibility for equity incentive

TABLE OF CONTENTS

awards, and we grant awards to substantially all of our employees. However, we recognize that equity awards dilute existing stockholders, and, therefore, we must responsibly manage our use of equity compensation. We are committed to effectively monitoring our equity compensation share reserve, including our “burn rate,” to ensure that we maximize stockholders’ value by granting the appropriate number of equity incentive awards necessary to attract, reward, and retain employees and non-employee directors. The tables below show our responsible overhang and burn rate percentages.

Overhang

The following table provides certain additional information regarding outstanding equity awards:


			As of April 1, 2026
Total number of shares of common stock subject to outstanding stock options			3,519,408
Weighted-average exercise price of outstanding stock options			$4.37
Weighted-average remaining term of outstanding stock options (in years)			6.29
Total number of shares of common stock subject to outstanding full value awards (RSUs and PSUs)			3,732,599
Total number of shares of common stock outstanding (including outstanding pre-funded warrants)⁽¹⁾			94,582,448
Per-share closing price of common stock as reported on Nasdaq Global Select Market on April 1, 2026			$0.8883

(1)	As of April 1, 2026, we had a total of 79,442,633 shares of common stock outstanding and 15,139,815 outstanding pre-funded warrants. Our pre-funded warrants are convertible 1:1 into shares of our common stock at an exercise price per share equal to $0.001 per share and are exercisable at any time.

Burn Rate

We monitor stockholder dilution by tracking the number of shares subject to equity awards that we grant annually, commonly referred to as the burn rate. Burn rate shows how rapidly a company is depleting its shares reserved for equity compensation awards and is defined for this purpose as the number of equity awards granted as incentives during the year divided by the weighted average number of shares of common stock outstanding during the year. We have calculated the burn rate for the past three fiscal years, as set forth in the following table:


	Total Number of Shares of Common Stock Subject to Stock Options Granted	Total Number of Shares of Common Stock Subject to Full Value Awards Granted	Weighted Average Number of Shares of Common Stock Outstanding⁽¹⁾	Burn Rate
Fiscal Year 2025	809,925	1,485,949	49,933,381	4.60%
Fiscal Year 2024	1,070,060	2,025,940	48,513,073	6.38%
Fiscal Year 2023	303,000	1,929,575	48,390,582	4.61%

(1)	This number includes both common stock outstanding and existing pre-funded warrants. Our pre-funded warrants are convertible 1:1 into shares of our common stock at an exercise price per share equal to $0.001 per share and are exercisable at any time.

Key Plan Features

The Amended 2024 Plan includes provisions that are designed to protect our stockholders’ interests and to reflect corporate governance best practices including:

•	No single trigger accelerated vesting upon change in control. The Amended 2024 Plan does not provide for any automatic mandatory vesting of awards upon a change in control.

•

Stockholder approval is required for additional shares. The Amended 2024 Plan does not contain an annual “evergreen” provision. Thus, stockholder approval is required each time we need to increase the share reserve allowing our stockholders the ability to have a say on our equity compensation programs.

TABLE OF CONTENTS

•

Prohibition on repricing. The Amended 2024 Plan specifically prohibits us from repricing any outstanding stock option or stock appreciation right by reducing the exercise price of the stock option or stock appreciation right or canceling any outstanding stock option or stock appreciation right that has an exercise price or strike price in excess of the current fair market value in exchange for cash or other awards without obtaining the approval of our stockholders within 12 months prior to such event.

•	Prohibition on the payment of dividends and dividend equivalents on unvested stock options or awards. The Amended 2024 Plan prohibits the payment or crediting of dividends or dividend equivalents with respect to any award until the underlying shares or units vest.

•

Prohibition on share recycling. Any shares of common stock reacquired or withheld (or not issued) by us to satisfy the exercise or purchase price of an award will no longer be available for issuance under the Amended Plan, including any shares subject to an award that are not delivered to a participant because such award is exercised through a reduction of shares subject to such award (i.e., “net exercised”). In addition, any shares reacquired or withheld (or not issued) by us to satisfy a tax withholding obligation in connection with an award, or any shares repurchased by us on the open market with the proceeds of the exercise or strike price of an option or stock appreciation right will no longer be available for issuance under the Amended 2024 Plan.

•

No discounted stock options or stock appreciation rights. All stock options and stock appreciation rights granted under the Amended 2024 Plan must have an exercise price or strike price equal to or greater than the fair market value of our common stock on the date the stock option or stock appreciation right is granted.

•

Flexibility in designing equity compensation scheme. The Amended 2024 Plan allows us to provide a broad array of equity incentives, including traditional option grants, stock appreciation rights, restricted stock awards, restricted stock unit awards, performance awards and other awards. By providing this flexibility we can quickly and effectively react to trends in compensation practices and continue to offer competitive compensation arrangements to attract and retain the talent necessary for the success of our business.

Description of the 2024 Equity Incentive Plan

The material features of the Amended 2024 Plan are described below. The following description of the Amended 2024 Plan is a summary only and is qualified in its entirety by reference to the complete text of the Amended 2024 Plan. Stockholders are urged to read the actual text of the Amended 2024 Plan in its entirety, which is attached as Annex A of the proxy statement filed with the SEC.

Awards. The Amended 2024 Plan will provide for the grant of incentive stock options, within the meaning of Section 422 of the Internal Revenue Code of 1986, as amended (the “Code”) to employees, including employees of any parent or subsidiary, and for the grant of nonstatutory stock options (“NSOs”), stock appreciation rights, restricted stock awards, restricted stock unit (“RSU”) awards, performance awards and other forms of awards to employees, directors, and consultants, including employees and consultants of our affiliates.

Authorized Shares. the aggregate number of shares of our common stock that may be issued pursuant to awards under the Amended 2024 Plan will not exceed 21,410,683 shares, which number is the sum of: (i) 6,150,000 shares initial reserved under the 2024 Plan, plus (ii) 9,600,000 shares that are subject to approval by our stockholders under this Proposal 5, plus (iii) the number of Returning Shares (as defined in the Amended 2024 Plan), if any, as such shares become available from time to time.

The maximum number of shares of our common stock that may be issued on the exercise of ISOs under the Amended 2024 Plan will be 40,610,683 shares.

Shares subject to awards granted under the Amended 2024 Plan that expire or terminate without being exercised in full or that are paid out in cash rather than in shares will not reduce the number of shares available for issuance under the Amended 2024 Plan. Any shares of our common stock previously issued pursuant to an award are forfeited back to or repurchased or reacquired by us because of a failure to meet a contingency or condition required for the vesting of such shares will be added back to the share reserve and again become available under the Amended 2024 Plan. However, the following types of shares subject to awards will reduce the share reserve and will not become available for the grant of new awards under the Amended 2024 Plan: (1) shares of common stock

TABLE OF CONTENTS

reacquired or withheld (or not issued) by us to satisfy the exercise, strike or purchase price of an award, including any shares subject to an award that are not delivered to a participant because the award is exercised through a reduction of shares subject to the award, (2) shares reacquired or withheld (or not issued) by us to satisfy a tax withholding obligation in connection with an award, and (3) any shares repurchased on the open market with the proceeds of the exercise or strike price of an option or stock appreciation right.

Eligibility. All of our employees, directors and consultants (including employees and consultants of our affiliates) are eligible to participate in the Amended 2024 Plan and may receive all types of awards other than ISOs. ISOs may be granted under the Amended 2024 Plan only to our (including our affiliates’) employees. As of April 1, 2026, approximately 18 employees, six non-employee directors and 17 consultants would be eligible to participate in the Amended 2024 Plan.

Plan Administration. Our board of directors, or a duly authorized committee of our board of directors, will administer the Amended 2024 Plan. Our board of directors may also delegate to one or more persons or bodies the authority to do one or more of the following: (i) designate recipients (other than officers) of specified awards, provided that no person or body may be delegated authority to grant an award to themself; (ii) determine the number of shares subject to such award; and (iii) determine the terms of such awards. Under the Amended 2024 Plan, our board of directors will have the authority to determine award recipients, grant dates, the numbers and types of awards to be granted, the applicable fair market value and the provisions of each award, including the period of exercisability and the vesting schedule applicable to an award.

The plan administrator will have the power to modify outstanding awards under the Amended 2024 Plan; provided, however, that the Amended 2024 Plan specifically prohibits the plan administrator from repricing any outstanding stock option or stock appreciation right by reducing the exercise price of the stock option or stock appreciation right, or from canceling any outstanding stock option or stock appreciation right that has an exercise price or strike price in excess of the current fair market value in exchange for cash or other awards, in either case without obtaining the approval of our stockholders within 12 months prior to such event.

Stock Options. The Amended 2024 Plan allows for the grant of ISOs and NSOs pursuant to stock option agreements adopted by the plan administrator. The plan administrator will determine the exercise price for stock options, within the terms and conditions of the Amended 2024 Plan, provided that the exercise price of a stock option generally cannot be less than 100% of the fair market value of our common stock on the date of grant for NSOs and 110% of the fair market value of the stock subject to the option on the date of grant for ISOs. Options granted under the Amended 2024 Plan will vest at the rate specified in the stock option agreement as determined by the plan administrator.

The plan administrator will determine the term of stock options granted under the Amended 2024 Plan, up to a maximum of 10 years. Unless the terms of an optionholder’s stock option agreement, or other written agreement between us and the recipient approved by the plan administrator, provide otherwise, if an optionholder’s service relationship with us or any of our affiliates ceases for any reason other than disability, death, or cause, the optionholder may generally exercise any vested options for a period of three months following the cessation of service. This period may be extended in the event that either an exercise of the option or an immediate sale of shares acquired upon exercise of the option following such a termination of service is prohibited by applicable securities laws or our insider trading policy. If an optionholder’s service relationship with us or any of our affiliates ceases due to death, or an optionholder dies within a certain period following cessation of service, the optionholder or a beneficiary may generally exercise any vested options for a period of 18 months following the date of death. If an optionholder’s service relationship with us or any of our affiliates ceases due to disability, the optionholder may generally exercise any vested options for a period of 12 months following the cessation of service. In the event of a termination for cause, options generally terminate upon the termination date. In no event may an option be exercised beyond the expiration of its term.

Acceptable consideration for the purchase of common stock issued upon the exercise of a stock option will be determined by the plan administrator and may include (1) cash, check, bank draft or money order, (2) a broker-assisted cashless exercise, (3) the tender of shares of our common stock previously owned by the optionholder, (4) a net exercise of the option if it is an NSO or (5) other legal consideration approved by the plan administrator.

TABLE OF CONTENTS

Unless the plan administrator provides otherwise, options or stock appreciation rights generally are not transferable except by will or the laws of descent and distribution. Subject to approval of the plan administrator or a duly authorized officer, an option may be transferred pursuant to a domestic relations order, official marital settlement agreement or other divorce or separation instrument.

Tax Limitations on ISOs. The aggregate fair market value, determined at the time of grant, of our common stock with respect to ISOs that are exercisable for the first time by an award holder during any calendar year under all of our stock plans may not exceed $100,000. Options or portions thereof that exceed such limit will generally be treated as NSOs. No ISO may be granted to any person who, at the time of the grant, owns or is deemed to own stock possessing more than 10% of our total combined voting power or that of any of our parent or subsidiary corporations unless (1) the option exercise price is at least 110% of the fair market value of the stock subject to the option on the date of grant and (2) the term of the ISO does not exceed five years from the date of grant.

Restricted Stock Unit Awards. The Amended 2024 Plan allows for the grant of RSU awards pursuant to restricted stock unit award agreements adopted by the plan administrator. RSU awards may be granted in consideration for any form of legal consideration that may be acceptable to our board of directors and permissible under applicable law. An RSU award may be settled by cash, delivery of stock, a combination of cash and stock as deemed appropriate by the plan administrator or in any other form of consideration set forth in the RSU award agreement. Additionally, dividend equivalents may be credited in respect of shares covered by an RSU award. Except as otherwise provided in the applicable award agreement or other written agreement between us and the recipient approved by the plan administrator, RSU awards that have not vested will be forfeited once the participant’s continuous service ends for any reason.

Restricted Stock Awards. The Amended 2024 Plan allows for the grant of restricted stock awards pursuant to restricted stock award agreements adopted by the plan administrator. A restricted stock award may be awarded in consideration for cash, check, bank draft or money order, past or future services to us or any other form of legal consideration that may be acceptable to our board of directors and permissible under applicable law. The plan administrator will determine the terms and conditions of restricted stock awards, including vesting and forfeiture terms. If a participant’s service relationship with us ends for any reason, we may receive any or all of the shares of common stock held by the participant that have not vested as of the date the participant terminates service with us through a forfeiture condition or a repurchase right.

Stock Appreciation Rights. The Amended 2024 Plan allows for the grant of stock appreciation rights pursuant to stock appreciation right agreements adopted by the plan administrator. The plan administrator will determine the purchase price or strike price for a stock appreciation right, which generally will not be less than 100% of the fair market value of our common stock on the date of grant. A stock appreciation right granted under the Amended 2024 Plan will vest at the rate specified in the stock appreciation right agreement as determined by the plan administrator. Stock appreciation rights may be settled in cash or shares of common stock or in any other form of payment as determined by our board of directors and specified in the stock appreciation right agreement.

The plan administrator will determine the term of stock appreciation rights granted under the Amended 2024 Plan, up to a maximum of 10 years. If a participant’s service relationship with us or any of our affiliates ceases for any reason other than cause, disability or death, the participant may generally exercise any vested stock appreciation right for a period of three months following the cessation of service. This period may be further extended in the event that exercise of the stock appreciation right following such a termination of service is prohibited by applicable securities laws. If a participant’s service relationship with us, or any of our affiliates, ceases due to disability or death, or a participant dies within a certain period following cessation of service, the participant or a beneficiary may generally exercise any vested stock appreciation right for a period of 12 months in the event of disability and 18 months in the event of death. In the event of a termination for cause, stock appreciation rights generally terminate immediately upon the occurrence of the event giving rise to the termination of the individual for cause. In no event may a stock appreciation right be exercised beyond the expiration of its term.

Performance Awards. The Amended 2024 Plan will permit the grant of performance awards that may be settled in stock, cash, or other property. Performance awards may be structured so that the stock or cash will be issued or paid only following the achievement of certain pre-established performance goals during a designated performance period. Performance awards that are settled in cash or other property are not required to be valued in whole or in part by reference to, or otherwise based on, the common stock.

TABLE OF CONTENTS

The performance criteria that will be used to establish such performance goals may be based on any one of, or combination of, the following as determined by the plan administrator: earnings (including earnings per share and net earnings); earnings before interest, taxes and depreciation; earnings before interest, taxes, depreciation and amortization; total stockholder return; return on equity or average stockholder’s equity; return on assets, investment, or capital employed; stock price; margin (including gross margin); income (before or after taxes); operating income; operating income after taxes; pre-tax profit; operating cash flow; sales or revenue targets; increases in revenue or product revenue; expenses and cost reduction goals; improvement in or attainment of working capital levels; economic value added (or an equivalent metric); market share; cash flow; cash flow per share; share price performance; debt reduction; customer satisfaction; stockholders’ equity; capital expenditures; debt levels; operating profit or net operating profit; workforce diversity; growth of net income or operating income; billings; preclinical development related compound goals; financing; regulatory milestones, including approval of a compound; stockholder liquidity; corporate governance and compliance; product commercialization; intellectual property; personnel matters; progress of internal research or clinical programs; progress of partnered programs; partner satisfaction; budget management; clinical achievements; completing phases of a clinical trial (including the treatment phase); announcing or presenting preliminary or final data from clinical trials, in each case, whether on particular timelines or generally; timely completion of clinical trials; submission of INDs and BLAs and other regulatory achievements; partner or collaborator achievements; internal controls, including those related to the Sarbanes-Oxley Act of 2002; research progress, including the development of programs; investor relations, analysts and communication; manufacturing achievements (including obtaining particular yields from manufacturing runs and other measurable objectives related to process development activities); strategic partnerships or transactions (including in-licensing and out-licensing of intellectual property); establishing relationships with commercial entities with respect to the marketing, distribution and sale of our product candidates (including with group purchasing organizations, distributors and other vendors); supply chain achievements (including establishing relationships with manufacturers or suppliers of active pharmaceutical ingredients and other component materials and manufacturers of our product candidates); co-development, co-marketing, profit sharing, joint venture or other similar arrangements; individual performance goals; corporate development and planning goals; and other measures of performance selected by the plan administrator.

The performance goals may be based on a company-wide basis, with respect to one or more business units, divisions, affiliates, or business segments, and in either absolute terms or relative to the performance of one or more comparable companies or the performance of one or more relevant indices. Unless specified otherwise (i) in the award agreement at the time the award is granted or (ii) in such other document setting forth the performance goals at the time the goals are established, we will appropriately make adjustments in the method of calculating the attainment of performance goals as follows: (1) to exclude restructuring and/or other nonrecurring charges; (2) to exclude exchange rate effects; (3) to exclude the effects of changes to generally accepted accounting principles; (4) to exclude the effects of any statutory adjustments to corporate tax rates; (5) to exclude the effects of items that are “unusual” in nature or occur “infrequently” as determined under generally accepted accounting principles; (6) to exclude the dilutive effects of acquisitions or joint ventures; (7) to assume that any business divested by us achieved performance objectives at targeted levels during the balance of a performance period following such divestiture; (8) to exclude the effect of any change in the outstanding shares of our common stock by reason of any stock dividend or split, stock repurchase, reorganization, recapitalization, merger, consolidation, spin-off, combination or exchange of shares or other similar corporate change, or any distributions to common stockholders other than regular cash dividends; (9) to exclude the effects of stock based compensation and the award of bonuses under our bonus plans; (10) to exclude costs incurred in connection with potential acquisitions or divestitures that are required to be expensed under generally accepted accounting principles; (11) to exclude the goodwill and intangible asset impairment charges that are required to be recorded under generally accepted accounting principles; and (12) to exclude the effects of the timing of acceptance for review and/or approval of submissions to the FDA, EMA or other comparable regulatory authority. In addition, we retain the discretion to reduce or eliminate the compensation or economic benefit due upon attainment of the goals. The performance goals may differ from participant to participant and from award to award.

Other Awards. The plan administrator will be permitted to grant other awards based in whole or in part by reference to our common stock. The plan administrator will set the number of shares under the award (or cash equivalent) and all other terms and conditions of such awards.

Changes to Capital Structure. In the event there is a specified type of change in our capital structure, such as a stock split, reverse stock split or recapitalization, appropriate adjustments will be made to (1) the class and

TABLE OF CONTENTS

maximum number of shares reserved for issuance under the Amended 2024 Plan, (2) the class and maximum number of shares by which the share reserve may increase automatically each year, (3) the class and maximum number of shares that may be issued on the exercise of ISOs and (4) the class and number of shares and exercise price, strike price or purchase price, if applicable, of all outstanding awards.

Corporate Transactions. In the event of a corporate transaction, unless otherwise provided in a participant’s award agreement or other written agreement with us or one of our affiliates or unless otherwise expressly provided by the plan administrator at the time of grant, any awards outstanding under the Amended 2024 Plan may be assumed, continued or substituted for by any surviving or acquiring corporation (or its parent company), and any reacquisition or repurchase rights held by us with respect to the award may be assigned to the successor (or its parent company). If the surviving or acquiring corporation (or its parent company) does not assume, continue or substitute for such awards, then (1) with respect to any such awards that are held by participants whose continuous service has not terminated prior to the effective time of the corporate transaction, or current participants, the vesting (and exercisability, if applicable) of such awards will be accelerated in full to a date prior to the effective time of the corporate transaction (contingent upon the effectiveness of the corporate transaction), and such awards will terminate if not exercised (if applicable) at or prior to the effective time of the corporate transaction, and any reacquisition or repurchase rights held by us with respect to such awards will lapse (contingent upon the effectiveness of the corporate transaction) and (2) any such awards that are held by persons other than current participants will terminate if not exercised (if applicable) prior to the effective time of the corporate transaction, except that any reacquisition or repurchase rights held by us with respect to such awards will not terminate and may continue to be exercised notwithstanding the corporate transaction.

In the event an award will terminate if not exercised prior to the effective time of a corporate transaction, the plan administrator may provide, in its sole discretion, that the holder of such award may not exercise such award but instead will receive a payment equal in value to the excess (if any) of (1) the per share amount payable to holders of common stock in connection with the corporate transaction, over (2) any per share exercise price payable by such holder, if applicable. In addition, any escrow, holdback, earn out or similar provisions in the definitive agreement for the corporate transaction may apply to such payment to the same extent and in the same manner as such provisions apply to the holders of common stock.

Under the Amended 2024 Plan, a corporate transaction is generally defined as the consummation of: (1) a sale of all or substantially all of our assets, (2) the sale or disposition of at least 50% of our outstanding securities, (3) a merger or consolidation where we do not survive the transaction or (4) a merger or consolidation where we do survive the transaction but the shares of our common stock outstanding immediately before such transaction are converted or exchanged into other property by virtue of the transaction.

Change in Control. Awards granted under the Amended 2024 Plan may be subject to acceleration of vesting and exercisability upon or after a change in control as may be provided in the applicable award agreement or in any other written agreement between us or any affiliate and the participant, but in the absence of such provision, no such acceleration will automatically occur.

Under the Amended 2024 Plan, a change in control is generally defined as: (1) the acquisition by any person or company of more than 50% of the combined voting power of our then outstanding stock; (2) a consummated merger, consolidation or similar transaction in which our stockholders immediately before the transaction do not own, directly or indirectly, more than 50% of the combined voting power of the surviving entity (or the parent of the surviving entity) in substantially the same proportions as their ownership immediately prior to such transaction; (3) a consummated sale, lease, exclusive license or other disposition of all or substantially all of our assets other than to an entity more than 50% of the combined voting power of which is owned by our stockholders in substantially the same proportions as their ownership of our outstanding voting securities immediately prior to such transaction; or (4) when a majority of our board of directors becomes comprised of individuals who were not serving on our board of directors on the date the Amended 2024 Plan was adopted by the board of directors, or the incumbent board, or whose nomination, appointment, or election was not approved by a majority of the incumbent board still in office.

Plan Amendment or Termination. Our board of directors has the authority to amend, suspend or terminate the Amended 2024 Plan, provided that such action does not materially impair the existing rights of any participant without such participant’s written consent. Certain material amendments also require the approval of our stockholders. No ISOs may be granted after the tenth anniversary of the date the Board first adopted the 2024 Plan. No awards may be granted under the Amended 2024 Plan while it is suspended or after it is terminated.

TABLE OF CONTENTS

U.S. Federal Income Tax Consequences

The following is a summary of the principal United States federal income tax consequences to participants and us with respect to participation in the Amended 2024 Plan. This summary is not intended to be exhaustive and does not discuss the income tax laws of any local, state or foreign jurisdiction in which a participant may reside. The information is based upon current federal income tax rules and therefore is subject to change when those rules change. Because the tax consequences to any participant may depend on his or her particular situation, each participant should consult the participant’s tax adviser regarding the federal, state, local and other tax consequences of the grant or exercise of an award or the disposition of stock acquired under the Amended 2024 Plan. The Amended 2024 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. Our ability to realize the benefit of any tax deductions described below depends on our generation of taxable income as well as the requirement of reasonableness, the provisions of Section 162(m) of the Code, and the satisfaction of our tax reporting obligations.

Nonstatutory Stock Options. Generally, there is no taxation upon the grant of an NSO if the stock option is granted with an exercise price equal to the fair market value of the underlying stock on the grant date. Upon exercise, a participant will recognize ordinary income equal to the excess, if any, of the fair market value of the underlying stock on the date of exercise of the stock option over the exercise price. If the participant is employed by us or one of our affiliates, that income will be subject to withholding taxes. The participant’s tax basis in those shares will be equal to their fair market value on the date of exercise of the stock option, and the participant’s capital gain holding period for those shares will begin on that date.

We will generally be entitled to a tax deduction equal to the taxable ordinary income realized by the participant.

Incentive Stock Options. The Amended 2024 Plan provides for the grant of stock options that are intended to qualify as “incentive stock options,” as defined in Section 422 of the Code. Under the Code, a participant generally is not subject to ordinary income tax upon the grant or exercise of an ISO. If the participant holds a share received upon exercise of an ISO for more than two years from the date the stock option was granted and more than one year from the date the stock option was exercised, which is referred to as the required holding period, the difference, if any, between the amount realized on a sale or other taxable disposition of that share and the participant’s tax basis in that share will be long-term capital gain or loss.

If, however, a participant disposes of a share acquired upon exercise of an ISO before the end of the required holding period, which is referred to as a disqualifying disposition, the participant generally will recognize ordinary income in the year of the disqualifying disposition equal to the excess, if any, of the fair market value of the share on the date of exercise of the stock option over the exercise price. However, if the sales proceeds are less than the fair market value of the share on the date of exercise of the stock option, the amount of ordinary income recognized by the participant will not exceed the gain, if any, realized on the sale. If the amount realized on a disqualifying disposition exceeds the fair market value of the share on the date of exercise of the stock option, that excess will be short-term or long-term capital gain, depending on whether the holding period for the share exceeds one year.

For purposes of the alternative minimum tax, the amount by which the fair market value of a share of stock acquired upon exercise of an ISO exceeds the exercise price of the stock option generally will be an adjustment included in the participant’s alternative minimum taxable income for the year in which the stock option is exercised. If, however, there is a disqualifying disposition of the share in the year in which the stock option is exercised, there will be no adjustment for alternative minimum tax purposes with respect to that share. In computing alternative minimum taxable income, the tax basis of a share acquired upon exercise of an ISO is increased by the amount of the adjustment taken into account with respect to that share for alternative minimum tax purposes in the year the stock option is exercised.

We are not allowed a tax deduction with respect to the grant or exercise of an ISO or the disposition of a share acquired upon exercise of an ISO after the required holding period. If there is a disqualifying disposition of a share, however, we will generally be entitled to a tax deduction equal to the taxable ordinary income realized by the participant, provided that either the employee includes that amount in income or we timely satisfy our reporting requirements with respect to that amount.

Restricted Stock Awards. Generally, the recipient of a restricted stock award will recognize ordinary income at the time the stock is received equal to the excess, if any, of the fair market value of the stock received over any amount paid by the recipient in exchange for the stock. If, however, the stock is not vested when it is received (for
