On or about April 30, 2025, we intend to first mail to most of our stockholders at the close of business on the Record Date a Notice of Internet Availability of Proxy Materials (the “Notice”) instead of a paper copy of the proxy materials and make this proxy statement and the form of proxy available.

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 April 30, 2025.

A stockholder’s election to receive proxy materials by mail or email will remain in effect until the stockholder terminates it.

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 May 10, 2025.

The Annual Meeting will be held on Wednesday, June 25, 2025, 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.

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.

Instructions on how to connect to the Annual Meeting and participate via the Internet, including how to demonstrate proof of stock ownership, are posted at www.virtualshareholdermeeting.com/SCYX2025.

Only stockholders of record at the close of business on April 28, 2025, will be entitled to vote at the Annual Meeting. On this record date, there were 39,020,274 shares of common stock outstanding and entitled to vote.

If on April 28, 2025, 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.

If on April 28, 2025, 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.

There are three matters scheduled for a vote:

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.

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:

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, 2025, 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.

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.

On each matter to be voted upon, you have one vote for each share of common stock you own as of April 28, 2025.

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.

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 and 3 without your instructions but may vote your shares on Proposal 2.

If you return a signed and dated proxy card or otherwise vote without marking voting selections, your shares will be voted, “For” the election of all our seven nominees for director, “For” the ratification of the Audit Committee’s selection of Deloitte & Touche LLP as the independent registered public accounting firm of SCYNEXIS for its fiscal year ending December 31, 2025, and “For” the advisory approval of the compensation of our named executive officers as disclosed in this proxy statement.

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.

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. We have hired Sodali & Co, 333 Ludlow Street, 5 Floor, South Tower, Stamford, CT 06902, to aid in the solicitation of proxies for a fee of $7,000, plus reasonable out-of-pocket expenses.

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.

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:

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

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.

To be considered for inclusion in next year’s proxy materials, your proposal must be submitted in writing by December 30, 2025, to our Corporate Secretary at SCYNEXIS, Inc., 1 Evertrust Plaza, 13^th Floor, Jersey City, New Jersey, 07302; provided, however, that if our 2026 annual meeting of stockholders is held before May 26, 2026, or after July 25, 2026, then your deadline is a reasonable amount of time prior to the date we begin to print and mail our proxy statement for the 2026 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, 2026, nor earlier than the close of business on February 25, 2026, except that if our 2026 annual meeting of stockholders is held before May 26, 2026, or after July 25, 2026, notice to be timely must be so delivered not earlier than the close of 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, to comply with the universal proxy rules, stockholders who intend to solicit proxies in support of director nominees other than our nominees must provide notice that sets forth the information required by Rule 14a-19 under the Exchange Act no later than April 26, 2026; provided, however, that, in the event that the

annual meeting is held before May 26, 2026, or after July 25, 2026, for your notice to be timely, it must be so received by our Corporate Secretary not earlier than the close of business on the date the later of sixty (60) days prior to such annual meeting and the tenth (10^th) day following the day on which public announcement of the date of such meeting is first made by us.

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.

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; and with respect to other proposals, votes “For,” “Against,” abstentions and, if applicable, 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.

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.”

The following table summarizes the minimum vote needed to approve each proposal and the effect of abstentions and broker non-votes.

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 39,020,274 shares outstanding and entitled to vote. Thus the holders of 19,510,138 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.

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.

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

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 seven 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 2024 annual meeting of stockholders.

Our seven nominees, their ages as of April 15, 2025, and their position currently held with SCYNEXIS, are as follows:

If elected at the Annual Meeting, each of these nominees would be elected and qualified to serve until the 2026 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 2024 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 seven 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.

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.

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.

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 2024 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.

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 2024 for each of the Audit, Compensation, and Nominating and Corporate Governance Committees:

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.

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:

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.

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:

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 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.

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.

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:

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 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, 13th 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.

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.

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 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.

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.

The Board met five times in 2024. 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 2024.

As required under applicable Nasdaq listing standards, in fiscal year 2024, SCYNEXIS’s independent directors met in regularly scheduled executive sessions at which only independent directors were present.

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, 13th 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.

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, 13th 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.

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.

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, 2025, 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.

The following table represents aggregate fees billed to us for the fiscal years ended December 31, 2024, and December 31, 2023, by Deloitte & Touche LLP, SCYNEXIS’s independent registered public accounting firm (in thousands).

All fees described above were approved by the Audit Committee.

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.

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, 2024, 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, 2024.

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 following table sets forth information regarding our executive officers as of April 15, 2025:

Dr. Angulo’s biography is included above under “Proposal 1 - Election of Directors.”

Ivor Macleod, MBA, CPA, has served as our Chief Financial Officer since October 2022. Prior to joining SCYNEXIS, Mr. Macleod served as Chief Financial Officer at Athersys, Inc., a clinical stage biotechnology company focused on regenerative medicine, from January 2020 to October 2022, in which role he was responsible for the Finance, Accounting, Investor Relations, and Corporate Communications departments.

Prior to joining Eisai, Mr. Macleod served as Vice President Finance – Merck Research Labs at Merck & Co., Inc., a global healthcare company that delivers innovative health solutions through its prescription medicines, vaccines, biologic therapies and animal health products, from 2012 to 2015.

Hoffmann-La Roche, Inc., a multinational health care company, in various roles, including as North American Chief Financial Officer from 2000 to 2011 as well as General Manager from 2010 to 2011. Mr. Macleod received his B.Sc. from St. Andrews University in Scotland and his M.B.A. from the University of Arizona. Mr. Macleod is a Certified Public Accountant licensed in Virginia.

Mr. Sukenick is a registered patent attorney. He obtained a B.S. in Biology and a B.A. in Chemistry from Duke University and a J.D. from Harvard University.

The following table sets forth information regarding the beneficial ownership of our common stock as of March 31, 2025, by the following:

The following table is based upon information supplied by officers, directors and principal stockholders and Schedules 13D and 13G filed with the SEC. Applicable percentages are based on 39,020,274 shares outstanding on March 31, 2025 adjusted as required by rules promulgated by the SEC.

The following table provides information with respect to all of our equity compensation plans in effect as of December 31, 2024.

The following table provides information regarding the compensation of our principal executive officer, our principal financial officer and our other highest paid executive officer as of December 31, 2024, for each of the years ended December 31, 2024 and 2023. We refer to these executive officers as our named executive officers.

The elements of the compensation program for our named executive officers include: base salary; an annual cash (non-equity) incentive plan bonus; long-term equity awards; and eligibility to participate in employee benefit and 401(k) plans. The Compensation Committee and the Board of Directors determines compensation amounts based on individual and corporate performance, market data, and other information following discussion and consultation with Pearl Meyer, the Compensation Committee’s independent compensation consultant.

Base salaries for our named executive officers are initially established through arm’s-length negotiation at the time the executive is hired or promoted, taking into account such executive’s qualifications, experience, prior salary, the scope of his or her responsibilities, and competitive market compensation paid by other companies for similar positions within the industry. Base salaries are reviewed annually, typically in connection with our annual performance review process, and adjusted from time to time to realign salaries with market levels of compensation paid by our peer companies and after taking into account individual responsibilities, performance and experience. In making decisions regarding salary increases, we draw upon the expertise of our independent compensation consultant, who provides comparative compensation data from similar companies in our industry. We also draw upon the experience of members of our Board of Directors with other companies. The Compensation Committee has not previously applied specific formulas to determine increases, although it has generally awarded increases as a percentage of an executive officer’s then-current base salary. This strategy is consistent with our intent of offering base salaries that are cost-effective while remaining competitive.

The compensation of our named executive officers other than our Chief Executive Officer is generally determined and approved by our Compensation Committee. The compensation of our Chief Executive Officer had, through March 2024, been determined and approved by our Compensation Committee without members of management present. The compensation of our Chief Executive Officer is now determined and approved by our Board of Directors without members of management present, based on recommendations from our Compensation Committee.

The 2024 annual base salaries for our named executive officers are set forth in the table below.

We seek to motivate and reward our executives for achievements relative to our corporate goals and expectations for each fiscal year. In 2024, each of our named executive officers was eligible to receive an annual performance bonus based on the achievement of performance goals as determined by our Board of Directors or an authorized committee thereof. Each named executive officer has a target bonus represented as a percentage of base salary (a “target bonus percentage”) each of which is set forth below:

The annual corporate performance goals are generally tied to achievement of research and development, finance, and other milestones important to our business. The Compensation Committee and our Board of Directors reviews the Company’s achievement of the corporate goals in their totality, taking into account the Company’s overall performance for the year.

The corporate goals established and achieved for 2024 included various research and development activities and objectives. The annual performance bonus for our Chief Executive Officer is tied entirely to the achievement of corporate goals which were achieved at 93% of target, resulting in an annual performance bonus of $307,412 for Dr. Angulo. For our other named executive officers, the annual performance bonus is determined based on the achievement of corporate goals (weighted 80%) which were achieved at 93% of target and individual performance (weighted 20%) which were achieved at 103% for each, resulting in annual performance bonuses of $171,912 and $169,146 for Mr. Macleod and Mr. Sukenick, respectively.

Our long-term, equity-based incentive awards are designed to align the interests of our executive officers and our other employees, non-employee directors, and consultants with the interests of our stockholders. Because vesting is generally subject to continued service over a period of several years following the date of grant, our equity-based incentives also serve as a retention device for executive officers, employees and other service providers. We generally provide initial equity-based incentive awards in connection with the commencement of employment of our executive officers as an inducement to commencement of employment, and we generally grant annual equity-based incentive awards to our executive officers shortly following the end of each year, each of which are subject to vesting over a period of multiple years in order to facilitate retention.

In January 2024, as part of its annual performance compensation review, the Compensation Committee (a) awarded the following restricted stock units to our named executive officers to acquire the following numbers of shares: Dr. Angulo, 290,590 shares; Mr. Macleod, 143,675 shares; and Mr. Sukenick, 143,675 shares, and (b) awarded options to our named executive officers to purchase the following number of shares: Dr. Angulo, 431,030 shares; Mr. Macleod, 215,515 shares; and Mr. Sukenick, 215,515 shares.

The shares subject to the restricted stock units described above vest over three years in equal annual installments. The stock options described above vest in equal monthly installments for 48 months as measured from the date of grant, subject to continued employment through the respective vesting date and allows for the purchase shares of our common stock at a price equal to $1.86, the fair market value of our common stock on January 26, 2024, the date of grant.

All of our named executive officers are eligible to participate in our employee benefit plans, including our medical, dental, vision and life plans, and our 401(k) plan, in each case on the same basis as all of our other employees. We pay the premiums for the life insurance for all of our employees, including our named executive officers.

The following table provides information regarding outstanding equity awards held by our named executive officers as of December 31, 2024.

We have entered into an employment agreement with each of our named executive officers. These agreements generally provide for “at will” employment and set forth the terms and conditions of employment of each named executive officer. Each of the executive officers entered into a confidentiality, invention and non-competition agreement with us, which is incorporated by reference in his employment agreement.

Employment agreement with Dr. Angulo. We entered into an employment agreement with Dr. Angulo in January 2023 setting forth the terms of Dr. Angulo’s employment as our Chief Executive Officer. Pursuant to the agreement, Dr. Angulo was entitled to receive an annual salary of $565,000 (which has been subsequently increased to $601,000 for 2024 and $631,050 for 2025) and is eligible to receive an annual performance bonus of up to 55% of his base salary and certain equity awards. Dr. Angulo is entitled to certain severance payments and benefits under his employment agreement, subject to executing a release and settlement agreement in a form acceptable to us, as further described below.

Employment agreement with Mr. Macleod. We entered into an employment agreement with Mr. Macleod in October 2022 setting forth the terms of Mr. Macleod’s employment as our Chief Financial Officer. Pursuant to the agreement, Mr. Macleod was entitled to receive an annual salary of $435,000 (which has been subsequently increased to $452,400 for 2024 and $470,496 for 2025) and is eligible to receive an annual performance bonus of up to 40% of his base salary and certain equity awards. Mr. Macleod is entitled to certain severance payments and benefits under his employment agreement, subject to executing a release and settlement agreement in a form acceptable to us, as further described below.

Employment agreement with Mr. Sukenick. We entered into an employment agreement with Mr. Sukenick in November 2017 setting forth the terms of Mr. Sukenick’s employment as our General Counsel. Pursuant to the agreement, Mr. Sukenick was entitled to receive an annual salary of $320,000 (which has been subsequently increased to $445,120 for 2024 and $462,925 for 2025) and is eligible to receive an annual performance bonus of up to 40% of his base salary and certain equity awards. Mr. Sukenick is entitled to certain severance payments and benefits under his employment agreement, subject to executing a release and settlement agreement in a form acceptable to us, as further described below.

Dr. Angulo, Mr. Macleod and Mr. Sukenick are entitled to certain severance payments and benefits under their respective employment agreements, subject to the applicable executive officer executing a release and settlement agreement in a form acceptable to us.

In the event of a termination without “just cause” by us or an executive officer’s resignation for “good reason” at any time other than during the twelve-month period following a “change in control” (or, for Dr. Angulo, during the ninety (90) day period prior to a “change in control”), the executive officer is eligible to receive the following payments and benefits:

In the event of a termination without “just cause” by us or an executive officer’s resignation for “good reason” at any time during the period that is within twelve months following a “change in control,” the executive officer is eligible to receive the following payments and benefits:

Each executive officer’s employment agreement contains a “better after-tax” provision, which provides that if any of the payments to the executive officer constitutes a parachute payment under Section 280G of the Internal Revenue Code, the payments will either be (i) reduced or (ii) provided in full to the executive, whichever results in the executive receiving the greater amount after taking into consideration the payment of all taxes, including the excise tax under Section 4999 of the Internal Revenue Code, in each case based upon the highest marginal rate for the applicable tax.

For purposes of the agreements described above:

In addition to the amounts presented above, each executive officer is eligible to receive any benefits accrued under our broad-based benefit plans, such as accrued vacation pay, in accordance with those plans and policies. In the event that we determine that an executive officer has earned all or a portion of his annual performance bonus, we will pay the executive officer such earned amount within 30 days of the date of our determination.

As required by Item 402(v) of Regulation S-K, we are providing the following graphs to illustrate the relationship between the pay and performance figures that are included in the pay versus performance tabular disclosure above. As noted above, compensation actually paid for purposes of the tabular disclosure and the following graphs were calculated in accordance with SEC rules and do not fully represent the actual final amount of compensation earned by or actually paid to our NEOs during the applicable years.

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

The following table sets forth information regarding compensation earned by our non-employee directors during the fiscal year ended December 31, 2024.

Information regarding Dr. Angulo, our Chief Executive Officer, is set forth under “Executive Compensation” above.

The following table sets forth information regarding the number of shares of our common stock subject to outstanding restricted stock units and stock options held by our non-employee directors as of December 31, 2024.

Our non-employee directors are compensated in accordance with the following policy:

Each non-employee director receives an annual base cash retainer of $45,000 for such service, to be paid quarterly. In addition, the chairman of the Board receives an additional annual base cash retainer of $35,000, to be paid quarterly.

In addition, each member of a committee receives compensation for service on a committee as follows:

The Board has established our non-employee director compensation policy with respect to equity grants to provide that each year on the first business day following the company’s annual meeting of stockholders, each non-employee director will automatically be granted a restricted stock unit to acquire 23,000 shares of the company’s common stock and an option to purchase 23,000 shares of the company’s common stock at an exercise price per share equal to the fair market value of a share of common stock on the date of grant. These annual grants will vest in full on the one-year anniversary of the grant date, provided that the non-employee director is providing continuous services on the applicable vesting date. If a new board member joins the Board, the director will be granted an initial restricted stock unit to acquire 46,000 shares of the company’s common stock and an initial option to purchase 46,000 shares of the company’s common stock at an exercise price per share equal to the fair market value of a share of common stock on the date of grant. These initial grants will vest over three years following the date of grant. One-third of the restricted stock units will vest each year on the anniversary of the date of grant. One-third of the options will vest on the first anniversary of the date of grant and the balance will vest in equal monthly installments over the remaining two-year period.

In addition, each non-employee director may elect to receive nonstatutory stock options in lieu of all or a portion of the cash compensation to which the non-employee director would otherwise be entitled to, as described above. Each non-employee director shall make their election prior to the period in which the compensation is to be earned. For each non-employee director electing to receive a nonstatutory stock option in lieu of such cash compensation, the date on which the nonstatutory stock options will be granted will be the date on which the cash compensation would otherwise have been earned, which is generally the first business day of each fiscal quarterly period, and the number of shares underlying such stock option will be determined by (i) dividing the cash compensation that the non-employee director elects to forgo in exchange for such nonstatutory stock options by 0.65, and (ii) dividing the result by the fair market value of a share of common stock on the date of grant. Each nonstatutory stock option granted in lieu of cash compensation pursuant to a non-employee director’s election will be 100% vested on the date of grant. After a non-employee director has elected to receive nonstatutory stock options in lieu of cash compensation, the option grants made to that non-employee director are awarded automatically pursuant to the previously described policy and no further action is required by the Board.

In February 2014, our board of directors adopted a policy that our executive officers, directors, nominees for election as a director, beneficial owners of more than 5% of any class of our common stock and any members of the immediate family of any of the foregoing persons are not permitted to enter into a related person transaction with us without the prior consent of our Audit Committee. Any request for us to enter into a transaction with an executive officer, director, nominee for election as a director, beneficial owner of more than 5% of any class of our common stock or any member of the immediate family of any of the foregoing persons in which the amount involved exceeds $120,000 and such person would have a direct or indirect interest must first be presented to our Audit Committee for review, consideration and approval. In approving or rejecting any such proposal, our Audit Committee is to consider the material facts of the transaction, including, but not limited to, whether the transaction is on terms no less favorable than terms generally available to an unaffiliated third party under the same or similar circumstances and the extent of the related person’s interest in the transaction.

Other than compensation arrangements for our directors and named executive officers previously described, since January 1, 2023, there have been no transactions with our directors and named executive officers to which we were a party or will be a party, in which:

The SEC has adopted rules that permit companies and intermediaries (e.g., brokers) to satisfy the delivery requirements for Notices of Internet Availability of Proxy Materials and Annual Meeting materials with respect to two or more stockholders sharing the same address by delivering a single Notice of Internet Availability of Proxy Materials or set of Annual Meeting materials addressed to those stockholders. This process, which is commonly referred to as “householding,” potentially means extra convenience for stockholders, allows us to save money by reducing the number of documents we must print and mail and helps protect the environment as well.

Householding is available to both registered stockholders (i.e., those stockholders with certificates registered in their name) and street name holders (i.e., those stockholders who hold their shares through a brokerage).

If you are a registered stockholder and have consented to our mailing of proxy materials and other stockholder information only to one account in your household, as identified by you, we will deliver or mail a single copy of our Notice of Internet Availability of Proxy Materials or set of Annual Meeting materials, as applicable, for all registered stockholders residing at the same address unless contrary instructions have been received from the affected stockholders. Once you have received notice from your broker that they will be “householding” communications to your address, “householding,” will continue until you are notified otherwise or until you revoke your consent. If, at any time, you no longer wish to participate in “householding” and would prefer to receive a Notice of Internet Availability of Proxy Materials or set of Annual Meeting materials, as applicable, please notify your broker or direct your written request to our Corporate Secretary at SCYNEXIS, Inc., 1 Evertrust Plaza, 13^th Floor, Jersey City, New Jersey, 07302, or contact Scott Sukenick, General Counsel, at (201) 884-5485. A separate copy of a Notice of Internet Availability of Proxy Materials or set of Annual Meeting materials will then promptly be delivered to you. Stockholders who currently receive multiple copies of the Notice of Internet Availability of Proxy Materials or set of Annual Meeting materials, as applicable, at their address and would like to request “householding” of their communications should contact their brokers.

The Board 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 accompanying proxy to vote, to the extent permitted by SEC rules, on such matters in accordance with their best judgment.

A copy of SCYNEXIS’s Annual Report to the Securities and Exchange Commission on Form 10-K for the fiscal year ended December 31, 2024, is available on our website, www.scynexis.com. A printed copy is also available without charge upon written request to: Corporate Secretary at SCYNEXIS, Inc., 1 Evertrust Plaza, 13^th Floor, Jersey City, New Jersey, 07302.
