Due to concerns regarding the COVID-19 pandemic and to assist in protecting the health and well-being of our stockholders and employees, this year’s Annual Meeting of stockholders of SCYNEXIS will be held virtually via the Internet. Stockholders will be able to listen and vote and submit questions regardless of location via the Internet at www.virtualshareholdermeeting.com/SCYX2022 by using the 16-digit control number included on your proxy card or voter instruction form and the instructions that accompanied your proxy materials. 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.

Only stockholders of record at the close of business on April 19, 2022, will be entitled to vote at the Annual Meeting. On this record date, there were 29,246,158 shares of common stock outstanding and entitled to vote.

If on April 19, 2022, your shares were registered directly in your name with SCYNEXIS’s transfer agent, American Stock Transfer & Trust Company, then you are a stockholder of record. Whether or not you plan to attend the meeting, we urge you to fill out and return the enclosed proxy card or vote by proxy over the telephone or on the internet as instructed below to ensure your vote is counted.

If on April 19, 2022, 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, or a Notice is, 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 four 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 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 using the enclosed 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 proxy card. If you vote by proxy, your vote must be received by 11:59 p.m. Eastern Time on June 15, 2022, 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 19, 2022.

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. With respect to Proposal 4, we have not been advised as to whether the NYSE will deem this proposal as “routine” or “non-routine”; however, we believe that the NYSE will deem Proposal 4 (approval of an amendment to our Amended and Restated Certificate of Incorporation, as amended, to increase the number of authorized shares) a “routine” matter. Since we have not been advised as to how the NYSE will designate these provisions, we recommend that stockholders cast their votes by proxy to ensure that their shares are voted in the manner they wish.

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, 2022, “For” the advisory approval of the compensation of our named executive officers as disclosed in this proxy statement, and “For” the approval of an amendment to our Amended and Restated Certificate of Incorporation, as amended, to increase the number of authorized shares.

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.

If you receive more than one Notice or 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 proxy cards in the proxy materials or Notices 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 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 January [  ], 2023, to our Corporate Secretary at SCYNEXIS, Inc., 1 Evertrust Plaza, 13^th Floor, Jersey City, New Jersey, 07302; provided, however, that if our 2023 annual meeting of stockholders is held before May 17 2023, or after July 16, 2023, then the deadline is a reasonable amount of time prior to the date we begin to print and mail our proxy statement for the 2023 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 18, 2023, nor earlier than the close of business on February 16, 2023, except that if our 2023 annual meeting of stockholders is held before May 17, 2023, or after July 16, 2023, 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.

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,

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 in person at the Annual Meeting or represented by proxy. On the record date, there were 29,246,158 shares outstanding and entitled to vote. Thus the holders of 14,623,080 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 in person 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 2021 annual meeting of stockholders.

Our seven nominees, their ages as of May 1, 2022, 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 2023 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 SCYNEXIS’s policy to encourage directors and nominees for director to attend the Annual Meeting. All of our current directors attended the 2021 annual meeting of stockholders, with the exception of Mr. Hastings, who was unavailable.

Directors are elected by a plurality of the votes of the holders of shares present in person or by proxy and entitled to vote on the election of directors. Unless marked otherwise we will vote proxies returned to us for the nominees named above. The seven nominees receiving the highest number of affirmative votes will be elected. 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 SCYNEXIS. Each person nominated for election has agreed to serve if elected. SCYNEXIS’s 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.

There are no family relationships among our directors and executive officers.

The Board Diversity Matrix below provides the diversity statistics for our Board of Directors.

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 his 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 2021 and currently, other than Dr. Taglietti, our current 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. Taglietti 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 2021 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 CEO. 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 Radford as an independent compensation consultant. Radford serves as a compensation resource available to the Compensation Committee on an hourly basis. As part of its engagement, Radford 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. Radford 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., and 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, 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.

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, Radford, 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 four times in 2021. 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 2021.

As required under applicable Nasdaq listing standards, in fiscal year 2021, 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, 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.

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.

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, 2022, 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 affirmative vote of the holders of a majority of the shares present in person or represented by proxy and entitled to vote on the matter at the Annual Meeting will be required to ratify the selection of Deloitte & Touche LLP.

The following table represents aggregate fees billed to us for the fiscal years ended December 31, 2021, and December 31, 2020, 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, 2021, 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, 2021.

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.

Our Board of Directors has adopted resolutions approving and submitting to a vote of the stockholders an amendment to Article IV of our Amended and Restated Certificate of Incorporation, as amended, to increase the number of authorized shares of common stock from 100,000,000 to 150,000,000.

Our Board of Directors believes that the availability of additional authorized shares of common stock will provide us with the flexibility in the future to issue shares of our common stock (i) for general corporate purposes, including raising additional capital and settling outstanding obligations, (ii) in connection with present and future employee benefit programs and (iii) in connection with expanding our business through acquisitions of companies or assets. We have no plans, arrangements or understandings, whether written or oral, to issue any of the common stock that will be newly available following the approval of this proposal by our stockholders.

Our Board of Directors will determine whether, when and on what terms the issuance of shares of our common stock may be warranted in connection with any future actions. No further action or authorization by our stockholders will be necessary before the issuance of the additional shares of our common stock authorized under our Amended and Restated Certificate of Incorporation, as amended, except as may be required for a particular transaction by applicable law or regulatory agencies or by the rules of any stock market or exchange on which our common stock may then be listed.

Our Amended and Restated Certificate of Incorporation currently authorizes the issuance of 100,000,000 shares of common stock, par value $0.001 per share, and 5,000,000 shares of preferred stock, par value $0.001 per share. As of April 27, 2022, there were 32,579,491 shares of common stock outstanding and no shares of preferred stock outstanding. In addition, as of April 27, 2022, 45,379,650 shares of common stock were issuable upon the exercise of outstanding options and warrants and 1,138,200 shares of common stock were reserved for issuance in connection with the conversion of outstanding promissory notes.

The additional common stock proposed to be authorized pursuant to the amendment would have rights identical to the currently outstanding shares of our common stock. Approval of this Proposal 4 would not affect the rights of the holders of currently outstanding shares of our common stock, except for effects incidental to increasing the number of shares of our common stock outstanding if such additional authorized shares are issued, such as dilution of any earnings per share and voting rights of current holders of common stock. The additional shares of common stock authorized by the approval of this Proposal 4 could be issued by our Board without further vote of our stockholders except as may be required in particular cases by our Charter, applicable law, regulatory agencies or the rules of Nasdaq. Under our Charter, stockholders do not have preemptive rights to subscribe for additional securities that may be issued by us, which means that current stockholders do not have a prior right thereunder to purchase any new issue of common stock in order to maintain their proportionate ownership interests in SCYNEXIS. The proposed amendment to increase the authorized number of shares of common stock does not change the number of shares of preferred stock that the company is authorized to issue.

The Board reserves the right, notwithstanding stockholder approval and without further action by stockholders, to elect not to proceed with the increase in the authorized shares of common stock if the Board determines that such increase is no longer in the best interests of the company and our stockholders.

If approved, the amendment would amend and restate paragraph A of Article IV of the Amended and Restated Certificate of Incorporation to read in its entirety as follows:

“A. This Corporation is authorized to issue two classes of stock to be designated, respectively, “Common Stock” and “Preferred Stock.” The total number of shares which the Corporation is authorized to issue is 155,000,000 shares. 150,000,000 shares shall be Common Stock, each having a par value of $0.001. 5,000,000 shares shall be Preferred Stock, each having a par value of $0.001.”

The approval of this Proposal 4 could, under certain circumstances, have an anti-takeover effect or delay or prevent a change in control of the company by providing the company the capability to engage in actions that would be dilutive to a potential acquirer, to pursue alternative transactions, or to otherwise increase the potential cost to acquire control of the company. The additional shares of common stock that would become available for issuance if this Proposal 4 is adopted could be used by us to oppose a hostile takeover attempt or to delay or

prevent changes in control or management. For example, without further stockholder approval, the Board could adopt a “poison pill” which would, under certain circumstances related to an acquisition of our securities that is not approved by the Board, give certain holders the right to acquire additional shares of our common stock at a low price, or the Board could strategically sell shares of common stock in a private transaction to purchasers who would oppose a takeover or favor the current Board. Although this Proposal 4 to approve the amendment has been prompted by business and financial considerations and not by the threat of any hostile takeover attempt (nor is the Board currently aware of any such attempts directed at us), and the Board does not intend or view the proposed increase in the number of authorized shares of our common stock as an anti-takeover measure, stockholders should nevertheless be aware that approval of this Proposal 4 could facilitate future efforts by us to deter or prevent changes in control, including transactions in which our stockholders might otherwise receive a premium for their shares over then-current market prices.

The affirmative vote of the holders of a majority of the shares of the common stock outstanding on the record date will be required to approve this Proposal 4. As a result, abstentions and broker non-votes will have the same effect as “Against” votes.

The following table sets forth information regarding the beneficial ownership of our common stock as of March 31, 2022, 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 29,221,158 shares outstanding on March 31, 2022 adjusted as required by rules promulgated by the SEC.

See “Transactions With Related Persons” below for additional purchases of our securities by the entities in the table above subsequent to the effective date of the table above.

The following table provides information with respect to all of our equity compensation plans in effect as of December 31, 2021.

The following table provides information regarding the compensation of our principal executive officer and our other two highest paid executive officers during the years ended December 31, 2021 and 2020. We refer to these executive officers as our named executive officers.

Our executive officers receive annual salaries, may receive annual cash performance bonuses based on a percentage of their respective annual salaries upon achievement of weighted performance goals as established by our board of directors or Compensation Committee, and equity incentive grants. Our Compensation Committee determines annual salaries, sets annual cash performance bonus targets, and determines annual cash performance bonuses to be paid, in each case based on individual and corporate performance, market data, and other information following discussion and consultation with Radford, the Compensation Committee’s independent compensation consultant. In January 2021, as part of its annual performance compensation review, the Compensation Committee awarded the following option awards to two of our named executive officers to purchase the following numbers of shares: Dr. Taglietti, 170,000 shares, and Dr. Angulo, 65,000 shares. The stock options allow these named executive officers to purchase shares of our common stock at a price equal to $7.47, the fair market value of our common stock on January 29, 2021, the date of grant. The shares subject to these stock options vest in equal monthly installments for 48 months as measured from January 29, 2021, subject to the continued employment of the named executive officer through the respective vesting date. The Compensation Committee determined these amounts based on individual and corporate performance, market data, and other information following discussion and consultation with Radford, the Compensation Committee’s independent compensation consultant. In May 2021, Ms. Coyne was hired as Chief Commercial Officer. Ms. Coyne’s compensation was established through arm’s length negotiations when she joined the company. She was granted RSUs and options in connection with joining the company.

The following table provides information regarding outstanding equity awards held by our named executive officers as of December 31, 2021.

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. Taglietti.

Dr. Taglietti

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 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.

Ms. Coyne is entitled to certain severance payments and benefits under her employment agreement, subject to executing a release and settlement agreement in a form acceptable to us, as further described below.

Dr. Taglietti, Dr. Angulo, and Ms. Coyne 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,” 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.

The following table sets forth information regarding compensation earned by our non-employee directors during the fiscal year ended December 31, 2021.

Information regarding Dr. Taglietti, 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 options held by our non-employee directors as of December 31, 2021.

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

Each non-employee director receives an annual base cash retainer of $40,000 for such service, to be paid quarterly. In addition, the chairman of the Board receives an additional annual base cash retainer of $35,000 (prior to January 2022, $30,000), 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 an option to purchase 10,000 (prior to June 2021, 5,500)

shares of the company’s common stock. These annual grants will have an exercise price per share equal to the fair market value of a share of common stock on the date of grant and 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 option to purchase 15,000 (prior to June 2021, 8,500) shares of the company’s common stock. Initial option grants to new board members will have an exercise price per share equal to the fair market value of a share of common stock on the date of grant and will vest over three years following the date of grant, with one-third of the options vesting on the first anniversary of the date of grant and the balance vesting equally monthly 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 company’s 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, 2020, the following are the only 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, 2021, 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.
