We have sent you the proxy notice because our Board of Directors is soliciting your proxy to vote at the 2021 Annual Meeting of Stockholders (the “Annual Meeting”), including at any adjournments or postponements of the meeting.

We have elected to provide access to the full proxy materials over the Internet and have provided our stockholders with instructions on how to access the proxy materials in the Notice of Internet Availability of Proxy Materials (the “Notice”) that you received.

All stockholders will have the ability to access the proxy materials on the website at www.proxyvote.com or may request a printed set of the proxy materials.

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/SCYX2021 by using the 16-digit control number included on your

Notice, 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 at the close of business on April 19, 2021 will be entitled to vote at the Annual Meeting. Beneficial owners of common stock at the close of business on April 19, 2021 will be able to vote at the Annual Meeting by following the instructions from the stockholder of record. On this record date, there were 20,630,750 shares of common stock outstanding and entitled to vote.

If on April 19, 2021, 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 vote by proxy over the telephone or on the internet as instructed below, or if you have received paper proxy materials to fill out and return the proxy card you would have received, to ensure your vote is counted.

If on April 19, 2021, 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. You are also invited to attend the Annual Meeting. However, since you are not the stockholder of record, if you wish to vote your shares at the Annual Meeting please follow the instructions from your broker, bank or other agent, or contact that organization 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 proxy card to vote, to the extent permitted by SEC rules, 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 an envelope provided with the proxy card if you have received one. 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 14, 2021, 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.

On each matter to be voted upon, you have one vote for each share of common stock you own as of April 19, 2021.

If you are a stockholder of record and do not vote by completing your proxy card, over telephone or 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 of 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, 2021, and “For” 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, to the extent permitted by SEC rules, 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 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 27, 2021, to our Corporate Secretary at SCYNEXIS, Inc., 1 Evertrust Plaza, 13^th Floor, Jersey City, New Jersey, 07302; provided, however, that if our 2022 annual meeting of stockholders is held before May 16, 2022, or after July 15, 2022, then the deadline is a reasonable amount of time prior to the date we begin to print and mail our proxy statement for the 2022 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 17, 2022, nor earlier than the close of business on February 15, 2022, except that if our 2022 annual meeting of stockholders is held before May 15, 2022, or after July 15, 2022, 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; 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 in person at the Annual Meeting or represented by proxy. On the record date, there were 20,630,750 shares outstanding and entitled to vote. Thus, the holders of 10,315,376 shares must be present in person 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.

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 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 2020 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 2020 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 Steven C. Gilman, Ph.D., Ann F. Hanham, Ph.D., and David Hastings, 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

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, Ann F. Hanham, Ph.D., and Philippe Tinmouth, 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. 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 five times in 2020. 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 2020.

As required under applicable Nasdaq listing standards, in fiscal year 2020, 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: Eric Francois, Chief Financial Officer, SCYNEXIS, Inc., 1 Evertrust Plaza, 13^th Floor, Jersey City, New Jersey, 07302, or via email to eric.francois@scynexis.com. The communications will be reviewed by the Chief Financial Officer. The Chief Financial Officer 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 Chief Financial Officer 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.

Our executive officers 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 agreed to by our executive officers. In prior years these performance bonuses have been disclosed in the summary compensation table as bonuses but, given the increasing structure of the bonus program, we have determined to categorize these payments as nonequity incentive plan compensation.

In January 2020, as part of its annual performance compensation review, the Compensation Committee awarded the following option awards to our named executive officers to purchase the following numbers of shares: Dr. Taglietti, 89,999 shares; Dr. Angulo, 44,999 shares; and Mr. Francois, 37,499 shares. The stock options allow our named executive officers to purchase shares of our common stock at a price equal to $8.63, the fair market value of our common stock on January 31, 2020, the date of grant. The shares subject to these stock options vest in equal monthly installments for 48 months as measured from January 31, 2020, subject to the continued employment of the named executive officer through the respective vesting date.

The following table provides information regarding outstanding equity awards held by our named executive officers as of December 31, 2020.

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. We entered into an employment agreement with Dr. Taglietti in February 2015 setting forth the terms of Dr. Taglietti’s employment as our Chief Executive Officer. Pursuant to the agreement, Dr. Taglietti was entitled to receive an annual salary of $480,000 (which was subsequently increased to $510,000 for 2017, $530,000 for 2018, $545,000 for 2019, $561,350 for 2020 and $579,320 for 2021) and is eligible to receive an annual performance bonus of up to 50% of his base salary (or such higher amount as determined by the Compensation Committee) and certain equity awards. 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. In April 2016, we and Dr. Taglietti amended the severance provisions of the employment agreement to avoid adverse tax consequences in the event that severance was to be paid.

Employment agreement with Mr. Francois. We entered into an employment agreement with Mr. Francois in November 2015 setting forth the terms of Mr. Francois’s employment as our Chief Financial Officer. Pursuant to the agreement, Mr. Francois will be entitled to receive an annual salary of $350,000 (which was subsequently increased to $360,500 for 2017, $371,400 for 2018, $382,600 for 2019, $394,080 for 2020 and $406,700 for 2021) and is eligible to receive an annual performance bonus of up to 35% of his base salary (or such higher amount as determined by the Compensation Committee) and certain equity awards. Mr. Francois 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 Dr. Angulo. We entered into an employment agreement with Dr. Angulo in July 2015 setting forth the terms of Dr. Angulo’s employment as our Chief Medical Officer. Pursuant to the agreement, Dr. Angulo was entitled to receive an annual salary of $390,000 (which was subsequently increased to $413,800 for 2017, $426,300 for 2018, $439,100 for 2019, $452,280 for 2020 and $466,760 for 2021) and is eligible to receive an annual performance bonus of up to 35% of his base salary and certain stock options. 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. In April 2016, we and Dr. Angulo amended the severance provisions of the employment agreement to avoid adverse tax consequences in the event that severance was to be paid.

Dr. Taglietti, Mr. Francois and Dr. Angulo 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 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 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 8,500 shares. 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.

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:

On December 21, 2020, we completed a public offering (the “December 2020 Public Offering”) of our common stock and warrants pursuant to our effective shelf registration. We sold an aggregate of (a) 8,340,000 shares of our common stock, par value $0.001 per share, (b) pre-funded warrants, in lieu of common stock, to purchase 5,260,000 shares of our common stock, par value $0.001 per share, and (c) two series of warrants, which will accompany the common stock or pre-funded warrants, to purchase up to an aggregate of 13,600,000 shares of our common stock. The pre-funded warrants entitle the holders to purchase up to 5,260,000 shares of common stock and have an unlimited term and an exercise price of $0.001 per share. Each of the two series of warrants entitle the holders to purchase up to an aggregate of 6,800,000 shares of common stock. The price to the public in the offering was $6.25 per share of common stock and accompanying warrants, or in the case of pre-funded warrants and accompanying warrants, $6.249 per pre-funded warrant and accompanying warrants. The following directors, executive officers and holders of 5% of our common stock purchased shares of our common stock and warrants in our December 2020 Public Offering at the public offering price:

On April 9, 2020, we entered into a Senior Convertible Note Purchase Agreement with Puissance Life Science Opportunities Fund VI (“Puissance”), under which we issued and sold to Puissance $10.0 million aggregate principal amount of our 6.0% Convertible Senior Notes due 2026, resulting in $9.3 million in net proceeds after deducting $0.7 million for an advisory fee paid to an advisor affiliated with Puissance and other issuance costs. See footnote [4] to the table set forth in “Security Ownership of Certain Beneficial Owners and Management” above for additional information regarding Puissance and entities affiliated with Puissance. Theodore Wang is the Chief Executive Officer and Chief Investment Officer of Puissance Life Science Opportunities Fund VI, and the Managing Member of Angel Pond Capital LLC, the advisor affiliated with Puissance.

On December 12, 2019, we completed a public offering (the “December 2019 Public Offering”) of our common stock and warrants pursuant to our effective shelf registration. We sold an aggregate of 38,888,889 shares of our common stock and warrants to purchase up to an aggregate of 38,888,889 shares of our common stock at a public offering price of $0.90 per share and accompanying warrant, and, pursuant to partial exercise of the underwriters’ option, sold additional warrants to purchase up to an aggregate of 5,833,333 shares of our common stock at a public offering price of $0.0010 per warrant. All warrants sold in the December 2019 Public Offering have an exercise price of $1.10 and an expiration date that is the earlier of (i) such date that is six months after we publicly announce the approval from the U.S. Food and Drug Administration for ibrexafungerp for the treatment of vulvovaginal candidiasis and (ii) June 12, 2023. The following directors, executive officers

and holders of 5% of our common stock purchased shares of our common stock and warrants in our December 2019 Public Offering at the public offering price:

On March 7, 2019, we entered into a Senior Convertible Note Purchase Agreement with Puissance, under which we issued and sold to Puissance $16.0 million aggregate principal amount of our 6.0% Convertible Senior Noted due 2025, resulting in $14.7 million in net proceeds after deducting $1.3 million for an advisory fee paid to an advisor affiliated with Puissance and other issuance costs.

Theodore Wang is the Chief Executive Officer and Chief Investment Officer of Puissance Life Science Opportunities Fund VI, and the Managing Member of Angel Pond Capital LLC, the advisor affiliated with Puissance.

Section 16(a) of the Securities Exchange Act of 1934 requires our executive officers, directors and persons who beneficially own more than 10% of our common stock to file initial reports of ownership and reports of changes in ownership with the SEC. These persons are required by SEC regulations to furnish us with copies of all Section 16(a) forms that they file.

To our knowledge, based solely on review of the forms furnished to us and written representations that no other reports were required during the fiscal year ended December 31, 2020, we believe that all Section 16(a) filing requirements applicable to the executive officers, directors and persons who beneficially own more than 10% of our common stock were complied with in 2020, except for the following: (a) each of our independent directors (Armando Anido, Steven C. Gilman, Ann F. Hanham, David Hastings, Guy Macdonald and Philippe Tinmouth) filed an amended Form 4 on March 31, 2021 to correct an administrative error that resulted in mistakenly reporting on July 6, 2020 that each independent director was granted an option to acquire 45,000 shares of common stock - the correct number was 55,000 shares, which subsequently became 5,500 shares following the 1-for-10 reverse stock split that took effect in July 2020; and (b) each of Eric Francois, our Chief Financial Officer, David Angulo, our Chief Medical Officer, and Scott Sukenick, our General Counsel, filed two Forms 4 late reporting, in each one, the withholding of shares to cover tax withholding obligations in connection with vesting of a restricted stock unit award.

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.
