PROXY STATEMENT

FOR THE ANNUAL MEETING OF STOCKHOLDERS

June 7, 2024

INFORMATION CONCERNING SOLICITATION AND VOTING

General

This proxy statement (“Proxy Statement”) is furnished in connection with the solicitation of proxies for use prior to or at the 2024 Annual Meeting of Stockholders (the “Annual Meeting”) of Fate Therapeutics, Inc. (the “Company”), a Delaware corporation, to be held at 9:00 a.m. Pacific Time on Friday, June 7, 2024, at the offices of Fate Therapeutics, Inc., 12278 Scripps Summit Drive, San Diego, California, 92131, and at any adjournments or postponements thereof for the following purposes:

On or about April 26, 2024, we intend to mail to all stockholders entitled to vote at the Annual Meeting a Notice of Internet Availability of Proxy Materials (the “Notice”) containing instructions on how to access this Proxy Statement and our 2023 Annual Report on Form 10-K (“Annual Report”).

Solicitation

This solicitation is made on behalf of the Board of Directors. We will bear the costs of preparing, mailing, online processing and other costs of the proxy solicitation made by our Board of Directors. Certain of our officers and employees may solicit the submission of proxies authorizing the voting of shares in accordance with the Board of Directors’ recommendations. Such solicitations may be made by telephone, facsimile transmission, email or personal solicitation. No additional compensation will be paid to such officers, directors or regular employees for such services. We will reimburse banks, brokerage firms and other custodians, nominees and fiduciaries for reasonable out-of-pocket expenses incurred by them in sending proxy materials to stockholders.

Important Notice Regarding the Availability of Proxy Materials

In accordance with rules and regulations of the Securities and Exchange Commission (the “SEC”), instead of mailing a printed copy of our proxy materials to each stockholder of record, the Company may furnish proxy materials via the internet. Accordingly, all of the Company’s stockholders will receive a Notice, to be mailed on or about April 26, 2024.

On the date of mailing the Notice, stockholders will be able to access all of the proxy materials on the website at www.proxydocs.com/FATE. The proxy materials will be available free of charge. The Notice will instruct you as to how you may access and review all of the important information contained in the proxy materials (including the Annual Report) over the internet or through other methods specified on the website. The website contains instructions as to how to vote by internet or over the telephone. The Notice also instructs you as to how you may request a paper or email copy of the proxy card. If you received a Notice and would like to receive printed copies of the proxy materials, you should follow the instructions for requesting such materials included in the Notice.

Voting Rights and Outstanding Shares

Only holders of record of the Company’s common stock as of the close of business on April 9, 2024 are entitled to receive notice of, and to vote at, the Annual Meeting. Each holder of our common stock will be entitled to one vote for each share held on all matters to be voted upon at the Annual Meeting. At the close of business on April 9, 2024, there were 113,816,708 shares of our common stock issued and outstanding.

A quorum of stockholders is necessary to take action at the Annual Meeting. Stockholders representing a majority of our common stock issued, outstanding and entitled to vote on any matter (present at the Annual Meeting or represented by proxy) will constitute a quorum. We will appoint an inspector of elections for the meeting to determine whether or not a quorum is present and to tabulate votes cast by proxy or at the Annual Meeting. Abstentions, withheld votes and broker non-votes (which occur when a broker, bank or other nominee holding shares for a beneficial owner does not vote on a particular matter because such broker, bank or other nominee does not have discretionary authority to vote on that matter and has not received voting instructions from the beneficial owner) are counted as present for purposes of determining the presence of a quorum for the transaction of business at the Annual Meeting.

If you are a beneficial owner of shares held in a brokerage account and you do not instruct your broker, bank or other agent how to vote your shares, your broker, bank or other agent may still be able to vote your shares in its discretion. Under the rules of the New York Stock Exchange, which are also applicable to Nasdaq-listed companies, brokers, banks and other securities intermediaries that are subject to New York Stock Exchange rules may use their discretion to vote your “uninstructed” shares on matters considered to be “routine” under New York Stock Exchange rules but not with respect to “non-routine” matters. Proposals 1, 3, 4, 5 and 6 are considered to be “non-routine” such that your broker, bank or other agent may not vote your shares on those proposals in the absence of your voting instructions. Conversely, Proposal 2 is considered to be “routine” and thus if you do not return voting instructions to your broker, your shares may be voted by your broker in its discretion on Proposal 2.

Votes Required for Each Proposal

The vote required and method of calculation for the proposals to be considered at the Annual Meeting are as follows:

Proposal One—Election of Directors. If a quorum is present, the three director nominees receiving the highest number of affirmative votes properly cast, submitted in person or by proxy, will be elected as directors. You may vote “FOR” one or more nominees or “WITHHOLD” from one or more nominees by specifying your vote for each nominee on your proxy card. This proposal is not considered to be a “routine” item under the rules of the

2

New York Stock Exchange, so if you do not instruct your broker how to vote with respect to this proposal, your broker may not vote on this proposal, and those votes will be counted as broker “non-votes.” Withheld votes and broker non-votes will have no effect on the outcome of the election of the directors. Our charter and our bylaws do not provide for cumulative voting in the election of directors.

Proposal Two—Approval of the Ratification of Ernst & Young LLP as the Independent Registered Public Accounting Firm. Approval of this proposal requires the affirmative vote of a majority of the votes properly cast for and against such matter. You may vote “FOR,” “AGAINST” or “ABSTAIN” from voting on this proposal. If you abstain from voting on this matter, your shares will not be counted as “votes cast” with respect to such matter, and the abstention will have no effect on the proposal. This proposal is considered to be a “routine” item under the rules of the New York Stock Exchange, and your broker will be able to vote on this proposal even if it does not receive instructions from you. Accordingly, we do not anticipate that there will be any broker non-votes on this proposal; however, any broker non-votes will have no effect on the proposal.

Proposal Three—Non-Binding Advisory Vote to Approve the Compensation of Our Named Executive Officers. Approval of this non-binding advisory proposal requires the affirmative vote of a majority of the votes properly cast for and against such matter. You may vote “FOR,” “AGAINST” or “ABSTAIN” from voting on this proposal. If you abstain from voting on this matter, your shares will not be counted as “votes cast” with respect to such matter and therefore an abstention will have no effect on the proposal. This proposal is not considered to be a “routine” item under the rules of the New York Stock Exchange, which are also applicable to Nasdaq-listed companies, brokers, banks and other securities intermediaries that are subject to New York Stock Exchange rules, so if you do not instruct your broker how to vote with respect to this proposal, your broker may not vote on this proposal, and those votes will be counted as broker “non-votes.” Broker non-votes will have no effect on the outcome of this proposal.

Proposal Four—Approval of Amendment to Our Amended and Restated Certificate of Incorporation to Include an Officer Exculpation Provision. Approval of this proposal requires the affirmative vote of a majority of the outstanding shares of common stock entitled to vote on the matter. You may vote “FOR,” “AGAINST” or “ABSTAIN” from voting on this proposal. Abstentions are considered shares present and entitled to vote on this proposal and therefor an abstention will have the same effect as a vote “AGAINST” this proposal. This proposal is not considered to be a “routine” item under the New York Stock Exchange, so if you do not instruct your broker how to vote with respect to this proposal, your broker may not vote on this proposal, and those votes will be counted as broker “non-votes.” Broker non-votes have the same effect as a vote “AGAINST” this proposal.

Proposal Five—Approval of Amendment and Restatement of Our 2022 Stock Option and Incentive Plan to Increase the Number of Shares of Common Stock Reserved for Issuance Thereunder. Approval of this proposal requires the affirmative vote of a majority of the votes properly cast for and against such matter. You may vote “FOR,” “AGAINST” or “ABSTAIN” from voting on this proposal. If you abstain from voting on this matter, your shares will not be counted as “votes cast” with respect to such matter and therefore an abstention will have no effect on the proposal. This proposal is not considered to be a “routine” item under the rules of the New York Stock Exchange, so if you do not instruct your broker how to vote with respect to this proposal, your broker may not vote on this proposal, and those votes will be counted as broker “non-votes.” Broker non-votes will have no effect on the outcome of this proposal.

Proposal Six—Approval of the adjournment of the Annual Meeting to the extent there are insufficient votes at the Annual Meeting to approve any of the above proposals. Approval of this proposal requires the affirmative vote of a majority of the votes properly cast for and against such matter. You may vote “FOR,” “AGAINST” or “ABSTAIN” from voting on this proposal. If you abstain from voting on this matter, your shares will not be counted as “votes cast” with respect to such matter and therefore an abstention will have no effect on the proposal. This proposal is not considered to be a “routine” item under the rules of the New York Stock Exchange, so if you do not instruct your broker how to vote with respect to this proposal, your broker may not vote on this proposal, and those votes will be counted as broker “non-votes.” Broker non-votes will have no effect on the outcome of this proposal.

We request that you vote your shares by proxy following the methods as instructed by the Notice: over the Internet, by telephone or by mail. If you choose to vote by mail, your shares will be voted in accordance with your voting instructions if the proxy card is received prior to or at the Annual Meeting. If you sign and return your proxy card but do not give voting instructions, your shares will be voted FOR (i) the election of each of the Company’s three (3) nominees as Class II directors; (ii) the ratification of the appointment of Ernst & Young LLP as the independent registered public accounting firm of the Company for the fiscal year ending December 31, 2024; (iii) the approval, on a non-binding, advisory basis, of the compensation of our named executive officers; (iv) the approval of an amendment to Fate Therapeutics, Inc. Amended and Restated Certificate of Incorporation to include an officer exculpation provision that limits the liability of certain of our officers as permitted under current Delaware law; (v) the approval of an amendment and restatement of the Fate Therapeutics, Inc. 2022 Stock Option and Incentive Plan to increase the number of shares reserved for issuance under the 2022 Plan by 8,000,000 shares; and (vi) as the proxy holder deems advisable, in his or her discretion, on other matters that may properly come before the Annual Meeting.

Voting by Proxy over the Internet or by Telephone

Stockholders whose shares are registered in their own names may vote by proxy by mail, over the Internet or by telephone. Instructions for voting by proxy over the Internet or by telephone are set forth on the Notice. The Internet and telephone voting facilities will close at 11:59 p.m. Pacific Time on Thursday, June 6, 2024. The Notice will also provide instructions on how you can elect to receive future proxy materials electronically or in printed form by mail. If you choose to receive future proxy materials electronically, you will receive an email next year with instructions containing a link to the proxy materials and a link to the proxy voting site. Your election to receive proxy materials electronically or in printed form by mail will remain in effect until you terminate such election.

If your shares are held in street name, the voting instruction form sent to you by your broker, bank or other nominee should indicate whether the institution has a process for beneficial holders to provide voting instructions over the Internet or by telephone. A number of banks and brokerage firms participate in a program that also permits stockholders whose shares are held in street name to direct their vote over the Internet or by telephone. If your bank or brokerage firm gives you this opportunity, the voting instructions from the bank or brokerage firm that accompany this Proxy Statement will tell you how to use the Internet or telephone to direct the vote of shares held in your account. If your voting instruction form does not include Internet or telephone information, please complete and return the voting instruction form in the self-addressed, postage-paid envelope provided by your broker. Stockholders who vote by proxy over the Internet or by telephone need not return a proxy card or voting instruction form by mail, but may incur costs, such as usage charges, from telephone companies or Internet service providers.

Revocability of Proxies

Any proxy may be revoked at any time before it is exercised by filing an instrument revoking it with the Company’s Secretary or by submitting a duly executed proxy bearing a later date than such proxy prior to the time of the Annual Meeting. Stockholders who have voted by proxy over the Internet or by telephone or have executed and returned a proxy and who then attend the Annual Meeting and desire to vote in person are requested to notify the Secretary in writing prior to the time of the Annual Meeting. We request that all such written notices of revocation to the Company be addressed to Cindy R. Tahl, Secretary, c/o Fate Therapeutics, Inc., at the address of our principal executive offices at 12278 Scripps Summit Drive, San Diego, CA 92131. Our telephone number is (858) 875-1800. Stockholders may also revoke their proxy by entering a new vote over the Internet or by telephone.

Voting Results

We plan to announce preliminary voting results at the Annual Meeting and will publish final results in a Current Report on Form 8-K to be filed with the SEC within four business days following the Annual Meeting.

Any stockholder who meets the requirements of the proxy rules under the Securities Exchange Act of 1934, as amended (the “Exchange Act”), may submit proposals to the Board of Directors to be presented at the 2025 annual meeting.

If that happens, we will publicly announce the deadline for submitting a proposal in a press release or in a document filed with the SEC. A proposal submitted outside the requirements of Rule 14a-8 under the Exchange Act will be considered untimely if received after March 12, 2025.

Our Amended and Restated Bylaws (“Bylaws”) also provide for separate notice procedures to recommend a person for nomination as a director or to propose business to be considered by stockholders at a meeting. To be considered timely under these provisions, the stockholder’s notice must be received by our Secretary at our principal executive offices at the address set forth above no earlier than February 7, 2025 and no later than March 9, 2025. Our Bylaws also specify requirements as to the form and content of a stockholder’s notice.

In addition to satisfying the foregoing requirements, to comply with the universal proxy rules, stockholders who intend to solicit proxies in support of director nominees other than the Company’s nominees must provide notice that sets forth the information required by Rule 14a-19 under the Exchange Act no later than April 8, 2025. Stockholder proposals and the required notice submitted by mail should be addressed to our Secretary at our principal executive offices at the address set forth above.

PROPOSAL 1

ELECTION OF DIRECTORS

General

Our certificate of incorporation provides for a Board of Directors that is divided into three classes. The term for each class is three years, staggered over time. This year, the term of the directors in Class II expires. Each of our current Class II directors except for Dr. Robert Hershberg will stand for re-election at the Annual Meeting. Our Board of Directors is currently comprised of ten members. If each of the Class II director nominees is elected at the Annual Meeting, the composition of our Board of Directors will be as follows: Class I—Drs. Robert S. Epstein, John D. Mendlein and Karin Jooss; Class II—Drs. William H. Rastetter and Yuan Xu, and Mr. Michael Lee; and Class III—Dr. Shefali Agarwal, and Messrs. J. Scott Wolchko and Timothy P. Coughlin.

In the absence of instructions to the contrary, the persons named as proxy holders in the accompanying proxy intend to vote in favor of the election of the nominees designated below to serve until the 2027 Annual Meeting of Stockholders and until their successors shall have been duly elected and qualified. Each nominee is currently a director. The Board of Directors expects that each nominee will be available to serve as a director, but if any such nominee should become unavailable or unwilling to stand for election, it is intended that the shares represented by the proxy will be voted for such substitute nominee as may be designated by the Board of Directors.

Robert Hershberg, M.D., Ph.D. will not stand for re-election as a director at the Annual Meeting, and, accordingly, the size of the Board of Directors will be reduced from ten directors to nine directors effective immediately following the Annual Meeting. This decision was made in consultation with Dr. Hershberg and was not due to any performance issues or any disagreement relating to our operations, policies, or practices. We would like to thank Dr. Hershberg for his years of service on our Board of Directors. With Dr. Hershberg’s departure, and the Board of Directors’ corresponding reduction in the number of directors serving at that time, the Board of Directors intends to continue its ongoing review of its composition.

The biographies of our directors and their ages as of April 1, 2024 are set forth below.

CORPORATE GOVERNANCE

Board of Directors’ Role in Risk Management

Risk is inherent with every business, and how well a business manages risk can ultimately determine its success. We face a number of risks, including risks relating to our financial condition, development and commercialization activities, operations and intellectual property. Management is responsible for the management of risks we face, on an on-going, day-to-day basis, while our Board of Directors, as a whole and through its committees, has responsibility for the oversight of risk management. In its risk oversight role, our Board of Directors has the responsibility to satisfy itself that the risk management processes designed and implemented by management are adequate and functioning as designed.

The role of our Board of Directors in overseeing the management of our risks is conducted primarily through committees of the Board of Directors, as disclosed in the descriptions of each of the committees below and in the charters of each of the committees. The full Board of Directors (or the appropriate board committee in the case of risks that are under the purview of a particular committee) discusses with management our major risk exposures, their potential impact on our company, and the steps we take to manage them. When a board committee is responsible for evaluating and overseeing the management of a particular risk or risks, the chairman of the relevant committee reports on the discussion to the full Board of Directors during the committee reports portion of the next board meeting. This enables our Board of Directors and its committees to coordinate the risk oversight role, as well as information regarding on-going risk management activities, particularly with respect to risk interrelationships.

Board of Directors and Committees of the Board

During 2023, the Board of Directors held a total of five meetings. During the year ended December 31, 2023, each of the directors then in office attended at least 75% of the aggregate of the number of Board of Directors meetings and the number of meetings held by all committees of the Board of Directors on which such director served.

Our Board of Directors has determined that all of our directors, except for Mr. Wolchko, are independent, as determined in accordance with the rules of The Nasdaq Stock Market (“Nasdaq”) and the SEC. In making such independence determination, the Board of Directors considered the relationships that each non-employee director has with us and all other facts and circumstances that the Board of Directors deemed relevant in determining their independence, including the beneficial ownership of our capital stock by each non-employee director. In considering the independence of the directors listed above, our Board of Directors considered the association of our directors with the holders of more than 5% of our common stock. There are no family relationships among any of our directors or executive officers.

The Board of Directors has a standing Audit Committee, Compensation Committee, and Nominating and Corporate Governance Committee. Each of our Audit Committee, Compensation Committee and Nominating and Corporate Governance Committee is composed entirely of independent directors in accordance with current Nasdaq listing standards. Furthermore, our Audit Committee meets the enhanced independence standards established by the Sarbanes-Oxley Act of 2002 and related rulemaking of the SEC. Copies of our Audit Committee, Compensation Committee and Nominating and Corporate Governance Committee charters and our code of business conduct and ethics are available, free of charge, on our website at http://ir.fatetherapeutics.com/corporate-profile.

Our Board of Directors also has a standing Science & Technology Committee, which is an advisory committee.

12

Audit Committee

Mr. Coughlin and Drs. Rastetter and Epstein currently serve on the Audit Committee, which is chaired by Mr. Coughlin. Our Board of Directors has designated Mr. Coughlin as an “Audit Committee financial expert,” as defined under the applicable rules of the SEC. The Audit Committee’s responsibilities include:

During 2023, the Audit Committee held four meetings.

Compensation Committee

Drs. Jooss and Xu and Mr. Coughlin currently serve on the Compensation Committee, which is chaired by Dr. Jooss. Dr. Jooss was appointed as Chairperson of the Compensation Committee and Dr. Xu was appointed as a member of the Compensation Committee in February 2023. Dr. Mendlein previously served as a member and Chairperson of the Compensation Committee from May 2018 to February 2023. The Compensation Committee’s responsibilities include:

13

During 2023, the Compensation Committee held nine meetings.

Nominating and Corporate Governance Committee

Drs. Epstein, Agarwal, and Hershberg currently serve on the Nominating and Corporate Governance Committee, which is chaired by Dr. Epstein. Dr. Xu previously served as a member of the Nominating and Corporate Governance Committee from February 2022 to February 2023. The Nominating and Corporate Governance Committee’s responsibilities include:

14

During 2023, the Nominating and Corporate Governance Committee held two meetings.

Science & Technology Committee (Advisory)

Our Board of Directors formed a Science & Technology Committee in September 2019. Drs. Agarwal, Jooss, Hershberg, Mendlein, and Xu and Mr. Lee currently serve on the Science & Technology Committee, which is chaired by Dr. Agarwal. The Science & Technology Committee’s responsibilities include assisting the Board of Directors’ oversight of our research and development activities and advising the Board of Directors with respect to strategic and clinical considerations.

Board Leadership

The positions of our Chairman of the Board of Directors and CEO are presently separated at Fate. Separating these positions allows our CEO to focus on our day-to-day business, while allowing the Chairman of the Board of Directors to lead our Board of Directors in its fundamental role of providing advice to and independent oversight of management. Our Board of Directors recognizes the time, effort and energy that the CEO must devote to his position in the current business environment, as well as the commitment required to serve as our Chairman of the Board of Directors, particularly as our Board of Directors’ oversight responsibilities continue to grow. Our Board of Directors also believes that this structure ensures a greater role for the independent directors in the oversight of our Company and active participation of the independent directors in setting agendas and establishing priorities and procedures for the work of our Board of Directors.

While our Bylaws and corporate governance guidelines do not require that our Chairman of the Board of Directors and CEO positions be separate, our Board of Directors believes that having separate positions and having an independent outside director serve as Chairman of the Board of Directors is the appropriate leadership structure for us at this time and demonstrates our commitment to good corporate governance. Our separate Chairman of the Board of Directors and CEO positions are augmented by the independence of nine of our ten directors, and our three entirely independent Board committees that provide appropriate oversight in the areas described above. At executive sessions of independent directors, these directors speak candidly on any matter of interest, without the CEO or other executives present. The independent directors met three times in 2023 without management present. We believe this structure provides consistent and effective oversight of our management and the Company.

Board Diversity

Our Board of Directors believes that directors who provide a significant breadth of experience, knowledge and abilities in areas relevant to our business, while also representing a diversity in race, ethnicity and gender, contribute to a well-balanced and effective board. Presently, three of our directors self-identify as female and three directors self-identify as having a demographic background from an underrepresented community.

As required by rules of the Nasdaq Stock Market that were approved by the Securities and Exchange Commission in August 2021, we are providing information about the gender and demographic diversity of our directors in the format required by Nasdaq rules. The information in the matrix below is based solely on information provided by our directors about their gender and demographic self-identification. Directors who did not answer or indicated that they preferred not to answer a question are shown as “did not disclose gender” or “did not disclose demographic background” below.

To see our Board Diversity Matrix as of April 1, 2023, please refer to our definitive proxy statement filed with the SEC on April 21, 2023.

Director Nominations

The director qualifications developed to date focus on what our Board of Directors believes to be essential competencies to effectively serve on the Board of Directors. The Nominating and Corporate Governance Committee must reassess such criteria annually and submit any proposed changes to the Board of Directors for approval. Presently, at a minimum, the Nominating and Corporate Governance Committee must be satisfied that each nominee it recommends has the highest personal and professional integrity, demonstrates exceptional ability and judgment and shall be most effective, in conjunction with the other nominees to the Board of Directors, in collectively serving the long-term interests of the stockholders.

In addition to those minimum qualifications, the Nominating and Corporate Governance Committee recommends that our Board of Directors select persons for nomination to help ensure that:

In addition to other standards the Nominating and Corporate Governance Committee may deem appropriate from time to time for the overall structure and compensation of the Board of Directors, the Nominating and Corporate Governance Committee considers the following factors when recommending that our Board of Directors select persons for nomination:

16

The Nominating and Corporate Governance Committee adheres to the following process for identifying and evaluating nominees for the Board of Directors. First, it solicits recommendations for nominees from non-employee directors, our CEO, other executive officers, third-party search firms or any other source it deems appropriate. The Nominating and Corporate Governance Committee then reviews and evaluates the qualifications of proposed nominees and conducts inquiries it deems appropriate; all proposed nominees are evaluated in the same manner, regardless of who initially recommended such nominee. In reviewing and evaluating proposed nominees, the Nominating and Corporate Governance Committee may consider, in addition to the minimum qualifications and other criteria for board membership approved by our Board of Directors from time to time, all facts and circumstances that it deems appropriate or advisable, including, among other things, the skills of the proposed nominee, his or her depth and breadth of business experience or other background characteristics, his or her independence and the needs of the Board of Directors. This process is designed to provide that the Board of Directors includes members with diverse backgrounds, skills and experience, including appropriate financial, scientific, medical and other expertise relevant to the business of the Company. Additionally, the Nominating and Corporate Governance Committee considers whether nominees assist in achieving a mix of board members that represents a diversity of background and experience, which is not only limited to race, gender or national origin, and is committed to actively seeking out highly qualified women and minority candidates, as well as candidates with diverse backgrounds, skills and experiences, to include in the pool from which board nominees are chosen. The Nominating and Corporate Governance Committee assesses its own performance on a periodic basis, and in doing so, gives consideration to its implementation of, and the results achieved through, this process.

If the Nominating and Corporate Governance Committee decides to retain a third-party search firm to identify proposed nominees, it has sole authority to retain and terminate such firm and to approve any such firm’s fees and other retention terms.

Each nominee for election as director at the 2024 Annual Meeting is recommended by the Nominating and Corporate Governance Committee and is presently a director and stands for re-election by the stockholders. From time to time, the Company may pay fees to third-party search firms to assist in identifying and evaluating potential nominees, although no such fees have been paid in connection with nominations to be acted upon at the 2024 Annual Meeting.

Pursuant to our Bylaws, stockholders who wish to nominate persons for election to the Board of Directors at an annual meeting must be a stockholder of record at the time of giving the notice, entitled to vote at the meeting, present (in person or by proxy) at the meeting and must comply with the notice procedures in our Bylaws. A stockholder’s notice of nomination to be made at an annual meeting must be delivered to our principal executive offices not less than 90 days nor more than 120 days before the anniversary date of the immediately preceding annual meeting. However, if an annual meeting is more than 30 days before or more than 60 days after such anniversary date, the notice must be delivered no later than the later of the 90th day prior to such annual meeting or the 10th day following the day on which the first public announcement of the date of such annual meeting was made. A stockholder’s notice of nomination may not be made at a special meeting unless such special meeting is held in lieu of an annual meeting. The stockholder’s notice must include the following information for the person making the nomination:

17

With respect to proposed director nominees, the stockholder’s notice must include all information required to be disclosed in a proxy statement in connection with a contested election of directors or otherwise required pursuant to Regulation 14A under the Exchange Act (including such person’s written consent to being named in the proxy statement as a nominee and to serving as a director if elected).

For matters other than the election of directors, the stockholder’s notice must also include a brief description of the business desired to be brought before the meeting, the reasons for conducting such business at the meeting and any material interest in such business of the stockholder(s) proposing the business.

The stockholder’s notice must be updated and supplemented, if necessary, so that the information required to be provided in the notice is true and correct as of the record date for the meeting and as of the date that is ten business days prior to the meeting.

The Board of Directors, a designated committee thereof or the chairman of the meeting will determine if the procedures in our Bylaws have been followed, and if not, declare that the proposal or nomination be disregarded.

The nominee must be willing to provide any other information reasonably requested by the Nominating and Corporate Governance Committee in connection with its evaluation of the nominee’s independence. There have been no material changes to the process by which stockholders may recommend nominees to our Board of Directors.

NON-EMPLOYEE DIRECTOR COMPENSATION

Non-Employee Director Compensation Policy in Effect Through April 3, 2023

Our Board of Directors has a non-employee director compensation policy that is designed to provide a total compensation package which enables us to attract and retain, on a long-term basis, high-caliber non-employee directors. Under this policy, all non-employee directors are paid cash compensation for service on the Board of Directors and committees of the Board of Directors as set forth below, prorated based on days of service during a calendar year.

In addition, under the policy as in effect through April 3, 2023, each new non-employee director initially appointed or elected to our Board of Directors was eligible to receive (i) an option grant to purchase an amount of shares of our common stock with a value of $400,000, subject to vesting in equal monthly installments during the three years following the grant date, and (ii) a grant of restricted stock units (“RSUs”) with a value of $400,000, subject to vesting in three (3) equal annual installments during the three years following the grant date, in each case subject to the director’s continued service on our Board of Directors. Thereafter, on the date of each annual meeting of stockholders, each continuing non-employee director was eligible to receive (i) an annual option grant to purchase an amount of shares of our common stock with a value of $200,000, subject to vesting in full upon the earlier of the first anniversary of the date of grant or the date of the following annual meeting of stockholders, and (ii) a grant of RSUs with a value of $200,000, subject to vesting in full upon the earlier of the first anniversary of the date of grant or the date of the following annual meeting of stockholders, subject to the director’s continued service on our Board of Directors. All of the foregoing options were to be granted with an exercise price per share equal to the fair market value of a share of our common stock on the date of grant.

We have agreed to reimburse all reasonable out-of-pocket expenses incurred by non-employee directors in attending Board of Directors and committee meetings.

20

Amended and Restated Non-Employee Director Compensation Policy in Effect Starting April 4, 2023

At the recommendation of our Compensation Committee, the Board of Directors adopted the Amended and Restated Non-Employee Director Compensation Policy (the “Amended Policy”) on April 4, 2023. Under the Amended Policy, non-employee directors will receive the same cash compensation as described above, but in lieu of the equity awards described above, each new non-employee director initially appointed or elected to our Board of Directors will receive an option grant to purchase 80,000 shares of our common stock, subject to vesting in equal monthly installments during the three years following the grant date, subject to the director’s continued service on our Board of Directors. Thereafter, on the date of each annual meeting of stockholders, each continuing non-employee director will be eligible to receive an annual option grant to purchase 40,000 shares of our common stock, subject to vesting in full upon the earlier of the first anniversary of the date of grant or the date of the following annual meeting of stockholders, subject to the director’s continued service on our Board of Directors. All of the foregoing options will be granted with an exercise price per share equal to the fair market value of a share of our common stock on the date of grant. In the event of a Sale Event (as defined in the 2022 Plan), each outstanding equity retainer award granted pursuant to the Amended Policy will become 100% vested and exercisable.

The aggregate amount of compensation, including both equity compensation and cash compensation, paid to any non-employee director of Company in a calendar year period cannot exceed $1,500,000 in the first calendar year such individual becomes a non-employee director and $1,000,000 in any other calendar year.

PROPOSAL 2

RATIFICATION OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

The Audit Committee has appointed Ernst & Young LLP as the Company’s independent registered public accounting firm for 2024. Representatives of Ernst & Young LLP will attend the Annual Meeting and will have the opportunity to make a statement if they desire to do so. They will also be available to respond to appropriate questions.

The Company’s organizational documents do not require that the stockholders ratify the selection of Ernst & Young LLP as the Company’s independent registered public accounting firm, and stockholder ratification is not binding on the Company, the Board of Directors or the Audit Committee. The Company requests such ratification, however, as a matter of good corporate practice. Our Board of Directors, including our Audit Committee, values the opinions of our stockholders and, to the extent there is any significant vote against the ratification of the selection of Ernst & Young LLP as disclosed in this Proxy Statement, we will consider our stockholders’ concerns and evaluate what actions may be appropriate to address those concerns, although the Audit Committee, in its discretion, may still retain Ernst & Young LLP.

The following table shows information about fees billed to the Company by Ernst & Young LLP for the fiscal years ended December 31, 2023 and 2022:

Audit Committee Pre-Approval Policies

The Audit Committee is directly responsible for the appointment, retention and termination, and for determining the compensation, of the Company’s independent registered public accounting firm. The Audit Committee shall pre-approve all auditing services and the terms thereof and non-audit services (other than non-audit services prohibited under Section 10A(g) of the Exchange Act or the applicable rules of the SEC or the Public Company Accounting Oversight Board), except that pre-approval is not required for the provision of non-audit services if the “de minimis” provisions of Section 10A(i)(1)(B) of the Exchange Act are satisfied. The Audit Committee may delegate to the chairperson of the Audit Committee the authority to grant pre-approvals for audit and non-audit services, provided such approvals are presented to the Audit Committee at its next scheduled meeting. All services provided by Ernst & Young LLP during fiscal year 2023 were pre-approved by the Audit Committee in accordance with the pre-approval policy described above, and all audit-related fees, tax fees and other fees during the fiscal year 2023 were approved by the Audit Committee.

Required Vote

The ratification of the selection of Ernst & Young LLP requires the affirmative vote of a majority of the votes properly cast for and against the proposal at the Annual Meeting. Abstentions and broker non-votes will have no effect on this proposal.

23

Recommendation of the Board of Directors

THE BOARD OF DIRECTORS RECOMMENDS THAT THE STOCKHOLDERS VOTE FOR THE RATIFICATION OF THE APPOINTMENT OF ERNST & YOUNG LLP AS THE INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM OF THE COMPANY FOR ITS FISCAL YEAR ENDING DECEMBER 31, 2024.

PROPOSAL 3

NON-BINDING ADVISORY VOTE TO APPROVE THE COMPENSATION OF OUR NAMED EXECUTIVE OFFICERS

Section 14A of the Exchange Act requires that we provide our stockholders with the opportunity to vote to approve, on a non-binding, advisory basis, not less frequently than once every three years, the compensation of our named executive officers, or a Say-on-Pay Vote, as disclosed in this Proxy Statement in accordance with the compensation disclosure rules of the SEC. In addition, we are required under the Exchange Act to solicit our stockholders, at least once every six years, to vote, on a non-binding advisory basis, on the frequency of such Say-on-Pay Vote, or a “say-on-frequency” vote. At our 2019 Annual Meeting of Stockholders, our stockholders approved one year as the frequency for holding non-binding advisory votes to approve the compensation of our named executive officers. As part of that commitment and consistent with the results of the advisory say-on-frequency vote of our stockholders that was held at the 2019 Annual Meeting, our Board of Directors is providing the stockholders with an opportunity to partake, on an advisory basis, in a Say-on-Pay Vote. This vote is not intended to address any specific item of compensation, but rather the overall compensation of our named executive officers and the policies and practices described in this Proxy Statement. Our next non-binding, advisory say-on-frequency vote will be held before or during 2025.

Our compensation programs are designed to effectively align our executives’ interests with the interests of our stockholders by focusing on long-term equity incentives that correlate with the growth of sustainable long-term value for our stockholders.

Stockholders are urged to read the section titled “Executive Compensation ” in this Proxy Statement in particular, which discusses how our executive compensation policies and practices implement our compensation philosophy and contains tabular information and narrative discussion about the compensation of our named executive officers, in conjunction with the section titled “Compensation of Our Executive Officers,” which provides additional information on the 2023 compensation of our named executive officers. Our Board of Directors and our Compensation Committee believe that these policies and practices are effective in implementing our compensation philosophy and in achieving our compensation program goals.

The vote on this resolution is not intended to address any specific element of compensation; rather, the vote relates to the compensation of our named executive officers, as described in this Proxy Statement in accordance with the compensation disclosure rules of the SEC.

Accordingly, we are asking our stockholders to vote on the following resolution at the Annual Meeting:

RESOLVED, that the stockholders hereby approve, on a non-binding advisory basis, the compensation paid to the Company’s named executive officers, as disclosed in the Company’s Proxy Statement for the 2024 Annual Meeting of Stockholders, pursuant to the compensation disclosure rules of the SEC, including the compensation tables and the narrative discussions that accompany the compensation tables.

Required Vote

The approval of this advisory non-binding proposal requires the affirmative vote of a majority of the votes properly cast for and against the proposal at the Annual Meeting. Abstentions and broker non-votes will have no effect on this proposal.

The vote is advisory, which means that the vote is not binding on the Company, our Board of Directors or our Compensation Committee. To the extent there is any significant vote against our named executive officer compensation as disclosed in this proxy statement, our Compensation Committee will evaluate whether any actions are necessary to address the concerns of stockholders.

25

Recommendation of the Board of Directors

THE BOARD OF DIRECTORS RECOMMENDS THAT THE STOCKHOLDERS VOTE FOR THE APPROVAL, ON A NON-BINDING ADVISORY BASIS, OF THE COMPENSATION OF THE COMPANY’S NAMED EXECUTIVE OFFICERS, AS DISCLOSED IN THIS PROXY STATEMENT.

PROPOSAL 4

APPROVAL OF AMENDMENT TO OUR AMENDED AND RESTATED CERTIFICATE OF INCORPORATION TO INCLUDE AN OFFICER EXCULPATION PROVISION

Our Board of Directors believes that eliminating personal monetary liability for officers under certain circumstances is essential to attract, retain and motivate people with the necessary talent and experience to join the Company and to achieve our short- and long-term business objectives. In February 2024, our Board of Directors approved an amendment to our Amended and Restated Certificate of Incorporation (the “Charter”) to provide for the exculpation of liability for certain officers of the Company (“Charter Amendment”). We are requesting that our stockholders approve the Charter Amendment. If our stockholders approve the Charter Amendment, it will amend the current version of the Charter. In the event that our stockholders do not approve this Proposal 4, the Charter Amendment will not become effective, and the Charter will continue in its current form.

Background

In August 2022, the State of Delaware, which is the Company’s state of incorporation, enacted legislation that enables Delaware companies to limit the liability of certain officers in limited circumstances under Section 102(b)(7) of the Delaware General Corporation Law (“DGCL”).

Specifically, the amended Section 102(b)(7) of the DGCL allows us to add a provision to our certificate of incorporation that no officer of the Company shall be personally liable to the Company or our stockholders for monetary damages for breach of fiduciary duty as an officer, except for liability (i) for any breach of the officer’s duty of loyalty to the Company or its stockholders, (ii) for acts or omissions not in good faith or which involve intentional misconduct or a knowing violation of law, (iii) for any transaction from which the officer derived an improper personal benefit, or (iv) arising from any claim brought by or in the right of the Company.

Conditions and Limitations to Exculpation under DGCL Section 102(b)(7)

As amended, Section 102(b)(7) of the DGCL provides important conditions and limitations on a corporation’s exculpation of its officers for monetary damages from breaches of fiduciary duty.

Purpose for the Inclusion of an Officer Exculpation Provision

Our Board of Directors believes that eliminating personal monetary liability for officers under certain circumstances is reasonable and appropriate. Generally, claims against corporations for breaches of fiduciary duties are expected to continue increasing. Delaware corporations that fail to adopt officer exculpation provisions may experience a disproportionate amount of nuisance litigation and disproportionately increased costs in the form of increased director and officer liability insurance premiums, as well as diversion of management attention from the business of the corporation. Further, the Board of Directors anticipates that similar exculpation provisions are likely to continue to be adopted by the Company’s peers and others with whom the Company competes for executive talent. As a result, officer exculpation provisions may become necessary for Delaware

27

corporations to attract and retain experienced and qualified corporate officers. A Delaware corporation seeking to extend the benefits of the amended Section 102(b)(7) of the DGCL to its corporate officers must amend its certificate of incorporation, as the protections do not apply automatically and must be embedded in the corporation’s certificate of incorporation to be effective. Our Board of Directors believes the proposed Charter Amendment would better position us to recruit top officer candidates and retain our current officers and enable the officers to exercise their business judgment in furtherance of the interests of the stockholders without the potential for distraction posed by the risk of personal liability. Additionally, it would align the protections for our officers with those protections currently afforded to our directors. Accordingly, the Board of Directors has determined it advisable and in the best interests of the Company and its stockholders to seek stockholders’ approval for the Charter Amendment.

Effect of the Proposal if Approved

The following description of certain features of the Charter Amendment is qualified by the full text of the amendment, which is adding a new Article XI in the Charter and attached to this Proxy Statement as Annex A.

The Charter Amendment would provide for the elimination of personal monetary liability for certain officers only in connection with direct claims brought by stockholders, subject to the limitations described above. As is already the case with directors under the Charter, the Charter Amendment would not limit the liability of officers for any breach of the duty of loyalty to the Company or its stockholders, any acts or omissions not in good faith or which involve intentional misconduct or a knowing violation of the law, or any transaction from which the officer derived an improper personal benefit.

If this proposal to amend the Charter is approved by our stockholders at the annual meeting, it will become effective upon the filing of the Charter Amendment, and the resulting Charter Amendment will be filed with the Secretary of State of the State of Delaware shortly after the Annual Meeting. In accordance with the DGCL, however, the Board of Directors may abandon the Charter Amendment without further action by the stockholders at any time prior to the effectiveness of the filing of the Charter Amendment with the Secretary of State of the State of Delaware, notwithstanding stockholder approval. If our stockholders do not approve the Charter Amendment, the Charter will remain unchanged, our officers will not be entitled to exculpation under the DGCL, and the Charter Amendment will not be filed with the Delaware Secretary of State.

Required Vote

The approval of this proposal requires the affirmative vote of a majority of the outstanding shares of common stock entitled to vote on the matter. Abstentions and broker non-votes will have the same effect on the outcome of this proposal as a vote “AGAINST” this proposal.

Recommendation of the Board of Directors

THE BOARD OF DIRECTORS RECOMMENDS THAT THE STOCKHOLDERS VOTE FOR THE APPROVAL OF THE AMENDMENT TO OUR AMENDED AND RESTATED CERTIFICATE OF INCORPORATION TO INCLUDE AN OFFICER EXCULPATION PROVISION, AS DISCLOSED IN THIS PROXY STATEMENT.

PROPOSAL 5

APPROVAL OF AMENDMENT AND RESTATEMENT OF OUR 2022 STOCK OPTION AND INCENTIVE PLAN TO INCREASE THE NUMBER OF SHARES OF COMMON STOCK RESERVED FOR ISSUANCE THEREUNDER

Our Board of Directors believes that stock-based incentive awards play an important role in the success of the Company by encouraging and enabling the employees, officers, non-employee directors, and consultants of the Company upon whose judgment, initiative and efforts the Company largely depends for the successful conduct of its business to acquire a proprietary interest in the Company. In addition, our Board of Directors believes that providing such persons with a direct stake in the Company assures a closer identification of the interests of such individuals with those of the Company and its stockholders, thereby stimulating their efforts on the Company’s behalf and strengthening their desire to remain with the Company. In April 2024, our Board of Directors approved an amendment and restatement of our 2022 Plan, subject to stockholder approval, to, among other things, increase the number of shares of common stock authorized for issuance under the 2022 Plan by 8,000,000 shares. Based on the number of shares of common stock currently authorized and reserved for issuance under the 2022 Plan, this would represent an increase from 9,500,000 shares to 17,500,000 shares. We are requesting that our stockholders approve an amendment and restatement of our 2022 Plan to, among other things, increase the number of shares of common stock reserved for issuance under the 2022 Plan by 8,000,000 shares (the 2022 Plan, as amended and restated, the “2022 Amended Plan”). If our stockholders approve the 2022 Amended Plan, it will amend and restate the current version of the 2022 Plan and will otherwise continue in effect through its current term (June 2032), unless terminated earlier by our Board of Directors. In the event that our stockholders do not approve this Proposal 5, the 2022 Amended Plan will not become effective, and the 2022 Plan will continue in its current form through its current term, without the 8,000,000 additional shares becoming available for issuance under the plan.

We believe that our equity compensation program is integral to our ability to attract, retain and motivate key personnel, non-employee directors and consultants given the competition for highly skilled and experienced individuals among biotechnology and pharmaceutical companies. Additionally, we believe increases in our employees’ equity ownership positions are currently needed to provide greater retentive value and incentivize our key personnel, including certain members of our executive leadership team. Based on an analysis conducted by Aon, our compensation consultant, of our peer group’s equity ownership position for employees and our projected hiring requirements, we believe that the current number of shares available for issuance under the 2022 Plan is insufficient to meet our need to provide adequate retentive value to our existing employees and to hire new employees. Therefore, our Board of Directors believes that this amendment and restatement of our 2022 Plan, which authorizes the issuance of additional shares available for grant under the 2022 Plan, is necessary in order to attract and retain the high caliber talent required to accomplish our business objectives and align the interests of our employees with those of our stockholders.

Broad-Based Equity Compensation Program

Since our inception, we have compensated all eligible employees using a mix of cash and equity. Our broad-based equity program has allowed us to conserve our cash resources while motivating our employees to act in the company’s and our stockholders’ interests. The broad-based nature of our equity compensation program is an important element of our overall employee compensation program and reflects our philosophy that it is important for all of our employees to approach their jobs with a long-term perspective. The 2022 Amended Plan, if approved, will continue to provide opportunities for ownership of shares of our common stock through stock option grants, restricted stock unit grants and other stock-based awards to employees that in each case vest over time or on the basis of the achievement of performance objectives. Our equity compensation program rewards both past and future performance. The number of shares each employee is awarded on an annual basis is based on the employee’s performance rating for the prior year, with higher performance levels rewarded with more shares.

29

We are asking our stockholders to approve the 2022 Amended Plan so that we will have a sufficient reserve of common stock to continue incentivizing, attracting, and retaining talent in a highly competitive market and industry, and to align the interests of our employees with those of our stockholders. If our stockholders do not approve the 2022 Amended Plan, then 8,000,000 additional shares requested will not become available for issuance under the 2022 Plan. The 2022 Plan will otherwise remain in effect in accordance with its terms, and based on historical and current grant practices, we anticipate that we could deplete our share reserve prior to 2025, putting us at a severe competitive disadvantage by severely restricting our ability to offer equity incentives to motivate, attract, and retain our employees. In such event, our Board will consider whether to adopt alternative arrangements based on its assessment of our needs. We believe that the proposed share pool increase to the 2022 Plan is reasonable, appropriate, and in the best interests of our stockholders.

As of April 1, 2024, there were stock options to acquire 13,308,902 shares of common stock outstanding under our equity compensation plans (5,132,492 under our Amended and Restated 2013 Stock Option and Incentive Plan, as amended from time to time (the “2013 Plan”), 7,658,172 under our 2022 Plan and 518,238 under our Amended and Restated Inducement Equity Plan (the “Inducement Plan”)), with a weighted average exercise price of $11.83 ($19.24, $6.92 and $10.93 for stock options granted under our 2013 Plan, 2022 Plan and the Inducement Plan, respectively) and a weighted average remaining term of 7.6 years (4.9, 9.3 and 8.9 years for stock options granted under our 2013 Plan, 2022 Plan and the Inducement Plan, respectively). In addition, as of April 1, 2024, there were 2,456,139 unvested full value awards with time-based vesting (637,736, 1,769,403 and 49,000 under our 2013 Plan, 2022 Plan and the Inducement Plan, respectively) and 1,002,453 unvested full value awards with performance vesting (1,002,453 under our 2013 Plan and none under our 2022 Plan nor the Inducement Plan, respectively) outstanding under our equity compensation plans. Other than the foregoing, no awards under our equity compensation plans were outstanding as of April 1, 2024. As of April 1, 2024, there were 4,213,389 shares of common stock available for future grant under our 2022 Plan (which does not reflect the additional 8,000,000 shares reserved under the 2022 Amended Plan, as set forth in this proposal) and 610,750 shares of common stock available for future grant under our Inducement Plan.

Summary of Material Changes

The 2022 Amended Plan provides for the following:

Summary of Material Features of the 2022 Amended Plan

The material features of the 2022 Amended Plan are:

30

Based solely on the closing price of our common stock as reported by the Nasdaq Global Market on April 1, 2024 and the maximum number of shares that would have been available for awards as of such date under the 2022 Amended Plan, after taking into account the share increase submitted for stockholder approval in this Proposal 5, the maximum aggregate market value of the common stock that could potentially be issued under the 2022 Amended Plan is $123,900,000.

Rationale for Approving the 2022 Amended Plan

Equity incentive awards are an important component of our executive and non-executive employees’ compensation. The Compensation Committee and our Board of Directors believe that we must continue to offer a competitive equity compensation program in order to attract, retain and motivate the talented and qualified employees necessary for our continued growth and success, especially given our industry and geographic location, and that the 2022 Amended Plan is critical to our ongoing effort to build stockholder value. Our ability to issue equity compensation is a key component of our compensation strategy and represents a significant element of the compensation granted to all of our employees. Equity compensation will continue to be an important element of our compensation program as the Company increases in size and number of employees. If the 2022 Amended Plan is not approved by stockholders, our ability to attract, motivate and retain highly qualified talent through the issuance of additional equity awards would be materially curtailed and we would be forced to use more of our cash resources for compensation purposes. If our stockholders approve the 2022 Amended Plan, then we expect that we will be able to grant equity awards under the 2022 Amended Plan for approximately the next one to two years, depending on a variety of factors, including the future price of our common stock, our hiring activity during the next few years, and the rate of forfeitures of outstanding awards. Without stockholder approval of the 2022 Amended Plan, we would not be able to offer a competitive equity compensation program to attract, retain, and motivate the talented and qualified employees necessary for our

31

continued growth and success, especially in an industry that relies on equity compensation as a key component of overall employee compensation. Hence, the 2022 Amended Plan is critical to our ongoing effort to build stockholder value.

We manage our long-term stockholder dilution by limiting the number of equity incentive awards granted annually. The Compensation Committee carefully monitors our annual net burn rate, total dilution and equity expense in order to maximize stockholder value by granting only the number of equity incentive awards that it believes are necessary and appropriate to attract, reward and retain our employees. Our compensation philosophy reflects broad-based eligibility for equity incentive awards for high performing employees. By doing so, we link the interests of those employees with those of our stockholders and motivate our employees to act as owners of the business.

Burn rate

The following table sets forth information regarding historical awards granted and earned for the fiscal year 2021 through 2023 period, and the corresponding burn rate, which is defined as the number of shares subject to equity-based awards granted in a year divided by the weighted average number of shares of common stock outstanding for that year, for each of the last three fiscal years:

Our Compensation Committee determined the size of the reserved pool under the 2022 Amended Plan based on projected equity awards to anticipated new hires, projected annual equity awards to existing employees and an assessment of the magnitude of increase that our institutional investors and the firms that advise them would likely find acceptable. We anticipate that if our request to increase the share reserve is approved by our stockholders, it will provide us with enough shares for equity awards for the next one to two years, with such timing dependent on a variety of factors, including the future price of our common stock, our hiring activity during the next few years and the rate of forfeitures of outstanding awards. These factors may require us to reevaluate our current equity grant practices which could then cause the reserved pool under the 2022 Amended Plan to be depleted at a more rapid pace. The Compensation Committee believes that a request covering up the next one to two years is reasonable and allows the Board of Directors to better tie our long-term compensation strategy to our long-term business growth strategy.

Summary of the 2022 Amended Plan

The following description of certain features of the 2022 Amended Plan is intended to be a summary only. The summary is qualified in its entirety by the full text of the 2022 Amended Plan, which is attached hereto as Annex B.

Administration. The 2022 Amended Plan will be administered by either the Board of Directors or the Compensation Committee (the “Administrator”). The Administrator has full power to select, from among the individuals eligible for awards, the individuals to whom awards will be granted, to make any combination of

32

awards to participants, to modify or accelerate any award, and to determine the specific terms and conditions of each award, subject to the provisions of the 2022 Amended Plan. The Administrator may delegate to a committee consisting of one or more officers of the Company, including our Chief Executive Officer, the authority to grant awards to employees who are not subject to the reporting and other provisions of Section 16 of the Exchange Act are not members of the delegated committee, subject to certain limitations and guidelines.

Eligibility; 2022 Amended Plan Limits. All full-time and part-time officers, employees, non-employee directors and consultants of the Company and its affiliates are eligible to participate in the 2022 Amended Plan, subject to the discretion of the Administrator. As of April 1, 2024, approximately 193 individuals would have been eligible to participate in the 2022 Amended Plan had it been effective on such date, which includes four executive officers, 177 employees who are not executive officers, nine non-employee directors and three consultants. There are certain limits on the number of awards that may be granted under the 2022 Amended Plan. For example, no more than 17,500,000 shares of common stock may be granted in the form of incentive stock options.

Director Compensation Limit. The 2022 Amended Plan provides that the value of all awards awarded under the 2022 Amended Plan and all other cash compensation paid by the Company to any non-employee director in any calendar year shall not exceed $1,000,000; provided, however, that such amount shall be $1,500,000 for the calendar year in which the applicable non-employee director is initially elected or appointed to the Board of Directors.

Stock Options. The 2022 Amended Plan permits the granting of (1) options to purchase common stock intended to qualify as incentive stock options under Section 422 of the Code and (2) options that do not so qualify. Options granted under the 2022 Amended Plan will be non-qualified options if they fail to qualify as incentive options or exceed the annual limit on incentive stock options. Incentive stock options may only be granted to employees of the Company. Non-qualified options may be granted to any persons eligible to receive incentive options and to non-employee directors and consultants. The option exercise price of each option will be determined by the Administrator. Except in the case of options (i) granted pursuant to a transaction described in, and in a manner consistent with, Section 424(a) of the Code, (ii) granted to individuals who are not subject to U.S. income tax on the date of grant or (iii) that are compliant with Section 409A of the Code, the exercise price of an option may not be less than 100% of the fair market value of the common stock on the date of grant. Fair market value for this purpose will be determined by reference to the last reported sale price of the shares of common stock on the Nasdaq Global Market (or such other market on which our common stock is then principally listed). The exercise price of an option may not be reduced after the date of the option grant without stockholder approval, other than to appropriately reflect changes in our capital structure.

The term of each option will be fixed by the Administrator and may not exceed ten years from the date of grant. The Administrator will determine at what time or times each option may be exercised. Options may be made exercisable in installments and the exercisability of options may be accelerated by the Administrator. In general, unless otherwise permitted by the Administrator, no option granted under the 2022 Amended Plan is transferable by the optionee other than by will or by the laws of descent and distribution or pursuant to a domestic relations order, and options may be exercised during the optionee’s lifetime only by the optionee, or by the optionee’s legal representative or guardian in the case of the optionee’s incapacity.

Upon exercise of options, the option exercise price must be paid in full either in cash, by certified or bank check or other instrument acceptable to the Administrator or by delivery (or attestation to the ownership) of shares of common stock that are beneficially owned by the optionee and that are not subject to risk of forfeiture. Subject to applicable law, the exercise price may also be delivered to the Company by a broker pursuant to irrevocable instructions to the broker from the optionee. In addition, non-qualified options may be exercised using a net exercise feature which reduces the number of shares issued to the optionee by the number of shares with a fair market value equal to the exercise price.

33

To qualify as incentive options, options must meet additional federal tax requirements, including a $100,000 limit on the value of shares subject to incentive options that first become exercisable by a participant in any one calendar year.

Stock Appreciation Rights. The Administrator may award stock appreciation rights subject to such conditions and restrictions as the Administrator may determine. Stock appreciation rights entitle the recipient to shares of common stock or cash equal to the value of the appreciation in the stock price over the exercise price. Except in the case of stock appreciation rights (i) granted pursuant to a transaction described in, and in a manner consistent with, Section 424(a) of the Code, (ii) granted to individuals who are not subject to U.S. income tax on the date of grant or (iii) that are compliant with Section 409A of the Code, the exercise price may not be less than the fair market value of the common stock on the date of grant. The term of a stock appreciation right may not exceed ten years.

Restricted Stock. The Administrator may award shares of common stock to participants subject to such conditions and restrictions as the Administrator may determine. These conditions and restrictions may include the achievement of certain performance goals and/or continued employment with us through a specified restricted period. During the vesting period, restricted stock awards may be credited with dividend equivalent rights (but dividend equivalents payable with respect to restricted stock awards with vesting shall not be paid unless and until such vesting conditions are attained).

Restricted Stock Units. The Administrator may award restricted stock units to participants. Restricted stock units are ultimately payable in the form of shares of common stock or cash subject to such conditions and restrictions as the Administrator may determine. These conditions and restrictions may include the achievement of certain performance goals and/or continued employment with the Company through a specified vesting period. In the Administrator’s sole discretion, it may permit a participant to make an advance election to receive a portion of his or her future cash compensation otherwise due in the form of a restricted stock unit award, subject to the participant’s compliance with the procedures established by the Administrator and requirements of Section 409A of the Code. During the deferral period, the deferred stock awards may be credited with dividend equivalent rights.

Unrestricted Stock Awards. The Administrator may also grant shares of common stock that are free from any restrictions under the 2022 Amended Plan. Unrestricted stock may be granted to any participant in recognition of past services or other valid consideration and may be issued in lieu of cash compensation due to such participant.

Cash-Based Awards. The Administrator may grant cash bonuses under the 2022 Amended Plan to participants. The cash bonuses may be subject to the achievement of certain performance goals.

Dividend Equivalent Rights. The Administrator may grant dividend equivalent rights to participants, which entitle the recipient to receive credits for dividends that would be paid if the recipient had held specified shares of common stock. Dividend equivalent rights granted as a component of another award (other than a stock option or stock appreciation right) may be paid only if the related award becomes vested. Dividend equivalent rights may be settled in cash, shares of common stock or a combination thereof, in a single installment or installments, as specified in the award.

Change of Control Provisions. In the event of a “sale event,” as defined in the 2022 Amended Plan, awards under the 2022 Amended Plan may be assumed, continued or substituted. In the event that awards are not assumed, continued or substituted, the 2022 Amended Plan and all outstanding awards thereunder will terminate. In such case of termination, except as otherwise provided in the applicable award agreement, upon the effective time of the sale event, all awards with time-based conditions or restrictions will become vested and exercisable or non-forfeitable, and all awards with conditions and restrictions relating to the attainment of performance goals will be deemed vested and non-forfeitable in connection with a sale event and the target level of performance for each performance goal for the entire performance period will be deemed achieved. In addition, the Company may

34

make or provide for payment, in cash or in kind, to participants holding options and stock appreciation rights equal to the difference between the per share cash consideration and the exercise price of the options or stock appreciation rights (provided that, in the case of an option or stock appreciation right with an exercise price equal to or greater than the per share cash consideration, such option or stock appreciation right shall be cancelled for no consideration). The Company shall also have the option to make or provide for a payment, in cash or in kind, to grantees holding other awards in an amount equal to the per share cash consideration multiplied by the number of vested shares under such awards. All awards will terminate in connection with a sale event unless they are assumed by the successor entity.

Adjustments for Changes in Stock. The 2022 Amended Plan requires the Administrator to make appropriate and proportionate adjustments to the number of shares of common stock that are subject to the 2022 Amended Plan, to certain limits in the 2022 Amended Plan, and to any outstanding awards to reflect stock dividends, stock splits, extraordinary cash dividends and similar events.

Tax Withholding. Participants in the 2022 Amended Plan are responsible for the payment of any federal, state or local taxes that the Company is required by law to withhold upon the exercise of options or stock appreciation rights or vesting of other awards. The Administrator may require that tax withholding obligations be satisfied by withholding shares of common stock to be issued pursuant to exercise or vesting. The Administrator may also require our tax withholding obligation to be satisfied, in whole or in part, by an arrangement whereby a certain number of shares issued pursuant to any award are immediately sold and proceeds from such sale are remitted to us in an amount that would satisfy the withholding amount due. The Company has no duty or obligation to advise any participant as to the time or manner of exercising an award or to minimize the potential tax consequences of an award.

Amendments and Termination. Our Board of Directors may at any time amend or discontinue the 2022 Amended Plan and the Board of Directors and the Compensation Committee may at any time amend or cancel any outstanding award for the purpose of satisfying changes in the law or for any other lawful purpose. However, no such action may adversely affect any rights under any outstanding award without the holder’s consent. Without prior stockholder approval, in no event may the Administrator exercise its discretion to reduce the exercise price of outstanding stock options or stock appreciation rights, effect repricing through cancellation and re-grants or cancellation of stock options or stock appreciation rights in exchange for cash or other awards or effect cash buyouts of underwater stock options or stock appreciation rights. To the extent required under the rules of Nasdaq, any amendments that materially change the terms of the 2022 Amended Plan will be subject to approval by our stockholders. Amendments shall also be subject to approval by our stockholders if and to the extent determined by the Administrator to be required by the Code to preserve the qualified status of incentive options.

Effective Date of Plan. The 2022 Plan was initially approved by our Board of Directors on April 14, 2022 and by our stockholders on June 9, 2022. Awards of incentive options may be granted under the 2022 Plan until the tenth anniversary of April 14, 2022. The 2022 Amended Plan was approved by our Board of Directors on April 1, 2024. No other awards may be granted under the 2022 Amended Plan after June 9, 2032.

New Plan Benefits

Because the grant of awards under the 2022 Amended Plan is within the discretion of the Administrator, the Company cannot determine the dollar value or number of shares of common stock that will in the future be received by or allocated to any participant in the 2022 Amended Plan. Accordingly, in lieu of providing information regarding benefits that will be received under the 2022 Amended Plan, the following table provides information concerning the benefits that were received by the following persons and groups during 2023: each named executive officer; all current executive officers, as a group; all current directors who are not executive officers, as a group; and all current employees who are not executive officers, as a group.

35

Tax Aspects under the Code

The following is a summary of the principal federal income tax consequences of certain transactions under the 2022 Amended Plan. It does not describe all federal tax consequences under the 2022 Amended Plan, nor does it describe state or local tax consequences.

Incentive Stock Options. No taxable income is generally realized by the optionee upon the grant or exercise of an incentive stock option. If shares of common stock issued to an optionee pursuant to the exercise of an incentive stock option are sold or transferred after two years from the date of grant and after one year from the date of exercise, then (i) upon sale of such shares, any amount realized in excess of the option exercise price (the amount paid for the shares) will be taxed to the optionee as a long-term capital gain, and any loss sustained will be a long-term capital loss, and (ii) the Company will not be entitled to any deduction for federal income tax purposes. The exercise of an incentive stock option will give rise to an item of tax preference that may result in alternative minimum tax liability for the optionee.

If shares of common stock acquired upon the exercise of an incentive stock option are disposed of prior to the expiration of the two-year and one-year holding periods described above (a “disqualifying disposition”), generally (i) the optionee will realize ordinary income in the year of disposition in an amount equal to the excess (if any) of the fair market value of the shares of common stock at exercise (or, if less, the amount realized on a sale of such shares of common stock) over the option exercise price thereof, and (ii) we will be entitled to deduct such amount. Special rules will apply where all or a portion of the exercise price of the incentive stock option is paid by tendering shares of common stock.

If an incentive stock option is exercised at a time when it no longer qualifies for the tax treatment described above, the stock option is treated as a non-qualified stock option. Generally, an incentive stock option will not be eligible for the tax treatment described above if it is exercised more than three months following termination of employment (or one year in the case of termination of employment by reason of disability). In the case of termination of employment by reason of death, the three-month rule does not apply.

36

Non-Qualified Stock Options. No income is realized by the optionee at the time the non-qualified stock option is granted. Generally (i) at exercise, ordinary income is realized by the optionee in an amount equal to the difference between the option exercise price and the fair market value of the shares of common stock on the date of exercise, and we receive a tax deduction for the same amount, and (ii) at disposition, appreciation or depreciation after the date of exercise is treated as either short-term or long-term capital gain or loss depending on how long the shares of common stock have been held. Special rules will apply where all or a portion of the exercise price of the non-qualified stock option is paid by tendering shares of common stock. Upon exercise, the optionee will also be subject to Social Security taxes on the excess of the fair market value over the exercise price of the stock option.

Stock Appreciation Rights. No income will be recognized by a recipient upon the grant of either tandem or freestanding stock appreciation rights. For the year in which the stock appreciation right is exercised, the recipient will generally be taxed at ordinary income rates on the amount equal to the cash received plus the fair market value of any unrestricted shares received on the exercise.

Restricted Stock Awards. The recipient of a restricted stock award will generally be taxed at ordinary income rates on the fair market value of the restricted shares (reduced by any amount paid by the recipient for such restricted shares) at such time as the shares are no longer subject to restrictions. However, a recipient may elect under Section 83(b) of the Code (the election must be filed with the IRS within 30 days of the grant date) to be taxed at ordinary income rates on the difference between: (i) the fair market value of such shares of the Company’s common stock on the grant date, and (ii) the purchase price, if any, of the shares. If a Section 83(b) election has not been made, dividends received with respect to restricted shares will generally be taxed as ordinary income to the recipient. If a Section 83(b) election has been made, dividends will be taxed at dividend rates.

Restricted Stock Units. The recipient of a restricted stock unit will generally be taxed at ordinary income rates on the fair market value of the shares of the Company’s common stock awarded on the transfer date. The capital gains/loss holding period for such shares will also commence on such date.

Unrestricted Stock Awards. The recipient of an unrestricted stock award will generally be taxed at ordinary income rates on the difference between: (i) the fair market value of the shares of the Company’s common stock on the grant date, and (ii) the purchase price, if any, of the shares.

Cash-Based Awards. The recipient will generally be taxed at ordinary income rates on the amount equal to the cash received.

Dividend Equivalent Rights. There are generally no Federal income tax consequences to the recipient or the Company on the grant of a dividend equivalent right. When the dividend equivalent right is converted to cash and/or additional shares of common stock and distributed to the recipient of a dividend equivalent right, the cash or the fair market value of the shares of common stock will be taxable to the recipient as ordinary income and the Company will be entitled to a corresponding deduction for tax purposes.

Parachute Payments. The vesting of any portion of an option or other award that is accelerated due to the occurrence of a change in control (such as a sale event) may cause a portion of the payments with respect to such accelerated awards to be treated as “parachute payments” as defined in the Code. Any such parachute payments may be non-deductible to the Company, in whole or in part, and may subject the recipient to a non-deductible 20% federal excise tax on all or a portion of such payment (in addition to other taxes ordinarily payable).

Limitation on Deductions. Under Section 162(m) of the Code, the Company’s deduction for awards under the 2022 Plan may be limited to the extent that any “covered employee” (as defined in Section 162(m) of the Code) receives compensation in excess of $1 million a year.

Equity Compensation Plan Information

The following table sets forth information regarding outstanding shares reserved for future issuance under the Company’s equity compensation plans as of December 31, 2023.

Required Vote

The approval of this proposal requires the affirmative vote of a majority of the votes properly cast for and against the proposal at the Annual Meeting. Abstentions and broker non-votes will have no effect on this proposal.

Should stockholder approval not be obtained, the 2022 Amended Plan will not be implemented, and the 2022 Plan will continue in effect pursuant to its current terms and 8,000,000 additional shares of common stock shall not be available for issuance under the 2022 Plan. Without 8,000,000 additional shares of common stock available for issuance, the shares reserved under the 2022 Plan will be depleted by 2025 and the Company will not achieve its intended objectives of attracting and retaining employees.

Recommendation of the Board of Directors

THE BOARD OF DIRECTORS RECOMMENDS THAT THE STOCKHOLDERS VOTE FOR THE APPROVAL OF THE AMENDMENT AND RESTATEMENT OF OUR 2022 STOCK OPTION AND INCENTIVE PLAN TO INCREASE THE NUMBER OF SHARES OF COMMON STOCK RESERVED FOR ISSUANCE UNDER THE 2022 PLAN BY 8,000,000 SHARES.

EXECUTIVE COMPENSATION

Our Named Executive Officers (collectively, our “NEOs”) for 2023 are as follows:

2023 Executive Summary Compensation Table

The following table provides information regarding the total compensation, for services rendered in all capacities, that was paid or earned by our NEOs during the fiscal years ending December 31, 2023 and 2022.

41

Narrative Disclosure to Summary Compensation Table

Our Compensation Committee determines the overall compensation structure for our CEO and other NEOs and executives. Each year, the Compensation Committee reviews the Company’s compensation policies and programs to ensure that these policies and programs enhance shareholder value, align pay and performance, and attract and retain top executive talent. As part of this process, the Compensation Committee reviews our compensation practices and policies to help maintain appropriate base salary, annual bonus and equity compensation plans for our executives and determines the target total direct compensation opportunities for our NEOs. The Compensation Committee does not use a single method or measure in developing its recommendations, nor does it establish specific targets for the total direct compensation opportunities for our NEOs; however, the Compensation Committee generally begins its deliberations on cash and equity compensation levels with reference to various percentile levels for cash and equity compensation as reflected in competitive market data. Pursuant to our 2022 Plan, the Compensation Committee has delegated to our CEO the authority to approve grants of stock options or RSUs to new hires, subject to certain limitations for each level of employment and an annual aggregate maximum amount of awards that can be granted pursuant to such delegated authority.

The CEO makes recommendations to the Compensation Committee on the base salary and target incentive plans for the other NEOs. Such recommendations consider internal pay equity, changes in responsibilities, compensation levels for similar positions in the industry, Company performance, total targeted and historical compensation, and personal performance and contributions. The Compensation Committee weighs the CEO’s guidance as a part of a greater assessment of the Company’s strategic goals and corporate performance when setting executive officer pay. With respect to our CEO’s compensation, the same considerations are made; however, this process is formalized in the Compensation Committee’s charter, specifying that the CEO cannot be present during voting or deliberations concerning this individual’s compensation.

Pursuant to its charter, the Compensation Committee has the authority to retain compensation consultants to assist in its evaluation of executive and director compensation. The Compensation Committee engaged Aon’s Human Capital Solutions practice a division of Aon plc (“Aon”), formerly known as Radford, as an independent outside compensation consultant to perform compensation advisory services during 2023 and to assist with evaluating executive compensation. The Compensation Committee believes that working with an independent compensation consultant furthers the Company’s objectives to recruit and retain qualified executives, align executive interests with those of shareholders and ensure that executive compensation packages will appropriately motivate and reward ongoing achievement of business goals. Our Compensation Committee will continue to retain a consultant to provide similar information and analyses in future years for consideration in determining annual cash, equity and other compensation for our employees, executive officers and directors.

The Compensation Committee annually assesses whether the work of Aon as a compensation consultant has raised any conflict of interest and evaluates Aon’s independence and performance under the applicable listing standards of Nasdaq, taking into consideration the following factors: (i) the provision of other services, if any, to the Company by Aon; (ii) the amount of fees the Company paid to Aon; (iii) Aon’s policies and procedures that are designed to prevent conflicts of interest; (iv) any business or personal relationship of Aon or the individual compensation advisors employed by the firm with an executive officer of the Company; (v) any business or personal relationship of the individual compensation advisors with any member of the Compensation Committee; and (vi) any stock of the Company owned by Aon or the individual compensation advisors employed by the firm. In 2023, Aon did not provide any other services to the Company other than the consulting services to the Compensation Committee with respect to compensation matters and a subscription to the Radford compensation database. The Compensation Committee has determined, based on its analysis of the above factors, that the work of Aon and the individual compensation advisors employed by Aon as compensation consultants to the Company have not created any conflict of interest.

Base Salaries

The 2023 annual base salaries for Messrs. Wolchko and Dulac, Dr. Valamehr and Ms. Tahl were $645,000, $475,000, $500,000 and $475,000, respectively. Our Compensation Committee reviews the base salaries of our executive officers, including our NEOs, from time to time and makes adjustments (or, in the case of our CEO, may recommend adjustments for approval by the Board of Directors) as it determines to be reasonable and necessary to reflect the scope of the executive officer’s performance, contributions, responsibilities, experience, tenure, prior salary level, position (in the case of a promotion) and market conditions, including base salary amounts relative to similarly situated executive officers at peer group companies.

Bonuses

The Board of Directors adopted the Company’s Amended and Restated Senior Executive Cash Incentive Bonus Plan (the “Bonus Plan”), which applies to certain key executives, including our NEOs. The Bonus Plan provides for bonus payments based upon the attainment of certain performance metrics related to the Company’s corporate objectives. The target annual bonuses for Messrs. Wolchko and Dulac, Dr. Valamehr and Ms. Tahl were 60%, 40%, 40% and 40%, respectively, of the applicable NEO’s annual base salary. For the fiscal year ended December 31, 2023, the compensation committee determined a 70% achievement level of its corporate performance metrics for purposes of the NEO bonuses.

Equity Compensation

During the fiscal year ended December 31, 2023, we granted stock option awards to each of our NEOs, as described in more detail in the “Outstanding Equity Awards at Fiscal 2023 Year-End” table.

Perquisites or Personal Benefits

Currently, we do not view perquisites or other personal benefits as a significant component of our executive compensation program. Accordingly, we do not provide significant perquisites or other personal benefits to our executive officers, including our NEOs, except as generally made available to our employees, or in situations where we believe it is appropriate to assist an individual in the performance of his or her duties, to make him or her more efficient and effective, and for recruitment and retention purposes. During 2023, none of our NEOs received perquisites or other personal benefits that were, in the aggregate, $10,000 or more for each individual.

401(k) Plan and Other Benefits

We have established a 401(k) plan to allow our employees to save on a tax-favorable basis for their retirement. We match a portion of eligible contributions made by employees pursuant to the plan. The Company makes discretionary contributions to the 401(k) plan equal to 100 percent of each employee’s pretax contributions up to 20 percent of the IRS’ limits. We also pay, on behalf of our employees, a portion of the premiums for health, life and disability insurance.

Employment, Severance and Change in Control Arrangements with our Named Executive Officers

Employment Agreements with our NEOs

We have entered into a written employment offer letter agreement with each of our NEOs. These agreements set forth the basic terms and conditions of employment, including initial base salary, initial equity awards, eligibility to participate in our standard employee benefits plans, and the at-will employment relationship. These agreements also require that each NEO execute our standard employee confidentiality and assignment agreement.

43

J. Scott Wolchko

We initially entered into an employment agreement with Mr. Wolchko, dated September 17, 2007, which was amended and restated in its entirety by a new employment agreement, dated January 14, 2018, effective January 1, 2018 (the “CEO Employment Agreement”). The CEO Employment Agreement sets forth Mr. Wolchko’s then-current annual base salary, an option grant and his eligibility to participate in our incentive bonus and benefit plans generally. Pursuant to the CEO Employment Agreement, Mr. Wolchko is eligible to receive an annual incentive compensation at a target percentage of 50% his annual base salary, as determined by the Board of Directors or the Compensation Committee from time to time. Mr. Wolchko’s employment is at-will. In the event that Mr. Wolchko’s employment is terminated by the Company without “Cause” (other than due to death or disability) or by Mr. Wolchko for “Good Reason” (as such terms are defined in the CEO Employment Agreement), in each case outside of the “Sale Event Period” (as defined below), subject to his execution of a nonrevocable separation agreement and release, Mr. Wolchko will be entitled to (i) a lump sum cash payment equal to the sum of (A) twelve (12) months of Mr. Wolchko’s then-current base salary and (B) his annual target incentive compensation for the year of termination, (ii) full acceleration of vesting of all outstanding equity awards containing performance-based vesting conditions, only if such performance-based vesting conditions have been satisfied as of the date of termination, (iii) for all outstanding equity awards containing time-based vesting conditions, twelve (12) months of accelerated vesting; and (iv) payment of the premiums for Mr. Wolchko’s and his family’s participation in the Company’s group health care plans, subject to Mr. Wolchko’s copayment amount, for up to eighteen (18) months after such termination.

Pursuant to the CEO Employment Agreement, in the event that Mr. Wolchko’s employment is terminated by the Company without Cause (other than due to death or disability) or by Mr. Wolchko for Good Reason, in each case within the period beginning three months prior to and ending eighteen (18) months following a “Sale Event” (as defined in the 2013 Plan) (the “Sale Event Period”), subject to his execution of a nonrevocable separation agreement and release, Mr. Wolchko is entitled to (i) a lump sum cash payment equal to the sum of (A) eighteen (18) months of Mr. Wolchko’s then-current base salary (or base salary in effect immediately prior to the Sale Event, if higher) and (B) one and a half (1.5) times his annual target incentive compensation for the year of termination; (ii) full acceleration of vesting of all outstanding equity awards; provided, however, that for any equity awards that include a performance-based vesting condition, no acceleration of vesting will be provided unless the applicable performance-based vesting condition has been satisfied as of the date of Mr. Wolchko’s termination, provided further that, in determining whether achievement of a specified stock price has been satisfied, such price is satisfied to the extent that the consideration payable per share of common stock of the Company upon a Sale Event exceeds such stock price; and (iii) payment of the premiums for Mr. Wolchko’s and his family’s participation in the Company’s group health care plans, subject to Mr. Wolchko’s copayment amount, for up to eighteen (18) months after such termination.

The payments and benefits provided to Mr. Wolchko under the CEO Employment Agreements in connection with a change of control may not be eligible for federal income tax deduction for the Company pursuant to Section 280G of the Code. These payments and benefits may also be subject to an excise tax under Section 4999 of the Code. If the payments or benefits payable to Mr. Wolchko in connection with a change of control would be subject to the excise tax imposed under Section 4999 of the Code, then those payments or benefits will be reduced if such reduction would result in a higher net after-tax benefit to him.

Edward J. Dulac III

Mr. Dulac is a party to an at-will employment offer letter with us, dated May 20, 2020 (the “Dulac Offer Letter”). The Dulac Offer Letter sets forth Mr. Dulac’s initial annual base salary, initial option grant and his eligibility to participate in our incentive bonus and benefit plans generally. Pursuant to the Bonus Plan, Mr. Dulac is eligible to receive annual incentive compensation at a target percentage of 40% of his then-current annual base salary, as determined by the Board of Directors or the Compensation Committee. Mr. Dulac may be entitled to certain severance payments and other benefits under the SCCP described below.

Bahram Valamehr, Ph.D.

Dr. Valamehr is a party to an at-will employment offer letter with us, dated November 20, 2009 (the “Valamehr Offer Letter”). The Valamehr Offer Letter sets forth Dr. Valamehr’s initial annual base salary, initial option grant and his eligibility to participate in our incentive bonus and benefit plans generally. Pursuant to the Bonus Plan, Dr. Valamehr is eligible to receive annual incentive compensation at a target percentage of 40% of his then-current annual base salary, as determined by the Board of Directors or the Compensation Committee. Dr. Valamehr may be entitled to certain severance payments and other benefits under the SCCP described below.

Cindy R. Tahl, J.D.

Ms. Tahl is a party to an at-will employment offer letter with us, dated October 17, 2009 (the “Tahl Offer Letter”). The Tahl Offer Letter sets forth Ms. Tahl’s initial annual base salary, initial option grant, and her eligibility to participate in our incentive bonus and benefit plans generally. Pursuant to the Bonus Plan, Ms. Tahl is eligible to receive annual incentive compensation, for which the initial target annual incentive compensation will be 40% of her then-current annual base salary, as determined by the Board of Directors or the Compensation Committee. Ms. Tahl may be entitled to certain severance payments and other benefits under the SCCP described below.

Severance and Change in Control Policy

We consider it essential to the best interests of our stockholders to foster the continuous employment of our key management personnel. Accordingly, we believe that reasonable and competitive post-employment compensation arrangements are essential to attracting and retaining highly-qualified executives. We further believe that when recruiting executive talent these arrangements are necessary to offer compensation packages that are competitive. The Compensation Committee does not consider the specific amounts payable under these post-employment compensation arrangements, however, when determining the annual compensation of our NEOs.

Effective on January 14, 2018, the Compensation Committee adopted the Severance Change in Control Policy (the “SCCP”), in which all of our NEOs, except our CEO, participate. It provides certain protections in the event of certain qualifying terminations of employment, including a qualifying termination of employment in connection with a change in control of the company. Our CEO has similar terms included in his employment agreement that were negotiated in conjunction with his appointment as CEO. These arrangements are designed to provide reasonable compensation to the executive officer if their employment is terminated under certain circumstances to facilitate their transition to new employment. Further, in some instances we seek to mitigate any potential employer liability and avoid future disputes or litigation by requiring a departing executive officer to sign a separation and release agreement acceptable to us as a condition to receiving post-employment compensation payments or benefits.

We believe that these arrangements help maintain our executive officers continued focus and dedication to their assigned duties to maximize stockholder value if there is a potential transaction that could involve a change in control of the company. In this event, these arrangements keep our most senior executives focused on pursuing all corporate transaction activity in the best interests of our stockholders regardless of whether those transactions may result in their own job loss. Thus, these arrangements align the interests of our executives, including our NEOs, and our stockholders when considering our long-term future.

In determining payment and benefit levels under the various circumstances triggering post-employment compensation provisions under the SCCP and our CEO’s employment agreement, our Board of Directors has drawn a distinction between (i) voluntary terminations of employment without good reason or terminations of employment for cause and (ii) terminations of employment without cause or voluntary terminations of employment for good reason. Payment in the latter circumstances has been deemed appropriate in light of the

45

benefits described in the prior paragraph, as well as the likelihood that an executive officer’s departure is due, at least in part, to circumstances not within his or her control. In contrast, we believe that payments are not appropriate in the event of a termination of employment for cause or a voluntary resignation without good reason because such events often reflect either performance challenges or an affirmative decision by the executive to end his or her relationship without fault by the Company.

All payments and benefits in the event of a change in control of the Company are payable only if there is a subsequent loss of employment by an executive officer (a so-called “double-trigger” arrangement). In the case of the acceleration of vesting of outstanding equity awards, we use this double-trigger arrangement to protect against the loss of retention value following a change in control of the Company and to avoid windfalls, both of which could occur if vesting of either equity or cash-based awards accelerated automatically as a result of the transaction.

To receive payments and benefits under the SCCP, or in the case of the CEO, under his employment agreement, an executive officer must execute and not subsequently revoke a severance agreement within 60 days following the date of the termination of employment, including a general release of claims acceptable to us.

Under the SCCP (in which all of our NEOs, except our CEO, participate), if a participant is terminated by the Company without “Cause” or resigns for “Good Reason” (each term as defined in the SCCP), in each case, following the first anniversary of the participant’s first day of employment with the Company and not in connection with a Sale Event (as defined in the SCCP), the participant will be entitled to the following benefits, subject to his or her execution of an irrevocable release: (i) for all outstanding equity awards containing time-based vesting conditions, nine (9) months of accelerated vesting; provided, however, that for any equity awards that include a performance-based vesting condition, no acceleration of vesting will be provided unless the applicable performance-based vesting condition has been satisfied as of the date of the participant’s termination; (ii) a lump sum cash payment equal to nine (9) months of the participant’s then-current base salary; and (iii) payment of the employer portion of group health care benefits under COBRA for up to nine (9) months.

In addition, if a participant is terminated by the Company without Cause or resigns for Good Reason, in each case within the period beginning three (3) months prior to and ending twelve (12) months following a Sale Event, then, in lieu of the benefits described above, such participant will be entitled to the following benefits, subject to his or her execution of a an irrevocable release: (i) for all outstanding equity awards containing time-based vesting conditions, full acceleration of vesting; provided, however, that for any equity awards that include a performance-based vesting condition, no acceleration of vesting will be provided unless the applicable performance-based vesting condition has been satisfied as of the date of the participant’s termination; (ii) a lump sum cash payment equal to twelve (12) months of the participant’s then-current base salary; (iii) one (1) times the participant’s annual target incentive compensation for the year of termination; and (iv) payment of the employer portion of group health care benefits under COBRA for up to twelve (12) months.

The payments and benefits provided a participant under the SCCP may not be eligible for federal income tax deduction for the Company pursuant to Section 280G of the Code. These payments and benefits may also be subject to an excise tax under Section 4999 of the Code. If the payments or benefits payable to a participant would be subject to the excise tax imposed under Section 4999 of the Code, then those payments or benefits will be reduced to the extent necessary so that no portion of such payments or benefits will be subject to such excise tax or loss of tax deduction for the Company.

Participants who are party to an agreement or an arrangement with the Company that provides greater benefits in the aggregate than set forth in the SCCP are not eligible to receive any payments or benefits under the SCCP.

46

Outstanding Equity Awards at Fiscal 2023 Year-End

The following table sets forth certain information with respect to outstanding equity awards as of December 31, 2023 held by our NEOs. The equity awards are subject to certain acceleration of vesting provisions as described in the “Employment, Severance and Change in Control Arrangements with our Named Executive Officers” section above. Unless otherwise described in a footnote below, the vesting of each equity award is subject to the applicable NEO’s continued employment/service relationship with the Company through each applicable vesting date.

CERTAIN RELATIONSHIPS AND RELATED TRANSACTIONS

Other than the compensation agreements and other arrangements described under “Compensation of Executive Officers” and the transactions described below, since the beginning of the fiscal year ended December 31, 2022, there has not been and there is not currently proposed, any transaction or series of similar transactions to which we were, or will be, a party in which the amount involved exceeded, or will exceed, $120,000 (or, if less, 1% of the average of our total assets amounts as of the end of the fiscal year in which the transaction was entered into) and in which any director, executive officer, holder of five percent or more of any class of our capital stock or any member of the immediate family of, or entities affiliated with, any of the foregoing persons, had, or will have, a direct or indirect material interest.

Private Placement

On March 19, 2024, we entered into a securities purchase agreement (the “Purchase Agreement”) with a fund affiliated with Redmile Group, LLC (collectively, “Redmile”), pursuant to which Redmile purchased pre-funded warrants to purchase up to 3,636,364 shares of our common stock (the “Pre-Funded Warrants”) at an aggregate purchase price of approximately $20.0 million for a purchase price per Pre-Funded Warrant of $5.499. The exercise price of each Pre-Funded Warrant is $0.001. Pursuant to the Purchase Agreement, we have agreed to file a resale registration statement with the SEC as soon as practicable, and in all events by April 19, 2024, to register the resale of the shares of our common stock issuable upon the exercise of the Pre-Funded Warrants. Redmile is a beneficial owner of more than 5% of our outstanding common stock and is affiliated with Michael Lee, a member of our board of directors.

Indemnification Agreements

We have entered into indemnification agreements with or have contractual obligations to provide indemnification to each of our directors and intend to enter into such agreements with certain of our executive officers. These agreements require us, among other things, to indemnify these individuals for certain expenses (including attorneys’ fees), judgments, fines and settlement amounts reasonably incurred by such person in any action or proceeding, including any action by or in our right, on account of any services undertaken by such person on behalf of the Company or that person’s status as a member of our Board of Directors to the maximum extent allowed under Delaware law.

Equity Incentive Awards

For information regarding stock option awards and other equity incentive awards granted to our NEOs and directors, see “Election of Directors-Director Compensation” and “Compensation of Executive Officers.”

54

SECURITY OWNERSHIP OF CERTAIN BENEFICIAL OWNERS AND MANAGEMENT

The following table sets forth information with respect to the beneficial ownership of shares of our common stock by (i) each director, (ii) each named executive officer, (iii) all directors and executive officers as a group, and (iv) each person who we know beneficially owns more than 5% of our common stock as of March 31, 2024.

Beneficial ownership is determined in accordance with the rules of the SEC. These rules generally attribute beneficial ownership of securities to persons who possess sole or shared voting power or investment power with respect to those securities and include shares of common stock issuable upon the exercise of stock options that are immediately exercisable or exercisable within 60 days after March 31, 2024 and upon the vesting and settlement of RSU awards within 60 days after March 31, 2024, but excludes unvested stock options and unvested RSUs. Except as otherwise indicated, all of the shares reflected in the table are shares of common stock and all persons listed below have sole voting and investment power with respect to the shares beneficially owned by them, subject to applicable community property laws. The information is not necessarily indicative of beneficial ownership for any other purpose.

In computing the number of shares of common stock beneficially owned by a person and the percentage ownership of that person, we deemed outstanding shares of common stock subject to options or warrants held by that person that are currently exercisable or exercisable within 60 days of March 31, 2024, as well as common stock issuable upon the vesting and settlement of RSU awards held by that person within 60 days of March 31, 2024. We did not deem these shares outstanding, however, for the purpose of computing the percentage ownership of any other person. Shares beneficially owned include restricted shares of common stock acquired upon any early exercise of stock options granted under our 2007 Plan.

Percentage ownership calculations for beneficial ownership for each person or entity are based on 113,798,942 shares of our common stock outstanding as of March 31, 2024 and, except as set forth in footnote (2) below, do not take into account 13,805,540 shares of common stock issuable upon conversion of all 2,761,108 shares of our Class A Convertible Preferred Stock outstanding on such date.
