Our Director Nominees

You are being asked to vote on the election of Timothy P. Walbert and Paul Hoelscher as Class I directors, each to serve for a three-year term expiring at our 2027 Annual Meeting of Stockholders, or the 2027 Annual Meeting. The number of members of our board of directors, or Board, is currently set at nine members. We expanded the size of the Board from seven members to nine members on April 1, 2024 with the appointment of Timothy P. Walbert and Paul Hoelscher. Our Board is divided into three classes, each of which has a three-year term. Class I currently consists of four directors, Class II consists of three directors and Class III consists of two directors.

The term of office of our Class I directors, Richard Rodgers, Jinzi Wu, Ph.D., Timothy P. Walbert and Paul Hoelscher, expires at the Annual Meeting. On March 20, 2024, Mr. Rodgers and Dr. Wu notified our Board that they would not stand for re-election at the Annual Meeting. As a result, each of Mr. Rodger’s and Dr. Wu’s service as a member of our Board will end effective as of the date of the Annual Meeting, and, after careful consideration, our Board has elected to reduce the size of the Board from nine to seven directors, effective as of the date of the Annual Meeting.

We are nominating Timothy P. Walbert and Paul Hoelscher for re-election as Class I directors at our Annual Meeting to serve until the 2027 Annual Meeting and until their successors, if any, are elected or appointed, or their earlier death, resignation, retirement, disqualification or removal. Directors are elected by a plurality of the votes properly cast by our stockholders at the Annual Meeting. The nominees receiving the most FOR votes (among votes properly cast online at the meeting or by proxy) will be elected. If no contrary indication is made, shares represented by executed proxies will be voted FOR the election of Timothy P. Walbert and Paul Hoelscher. Each nominee has agreed to serve as a director if elected, and we have no reason to believe that any nominee will be unable to serve.

RECENT CORPORATE HIGHLIGHTS

•

In March 2024, we announced the appointment of Timothy P. Walbert and Paul Hoelscher to our Board effective April 1, 2024.

•

In January 2024, we sold 9,000,000 shares of our Series A common stock, or Series A common stock, in an underwritten public offering and received $104.7 million in net proceeds. Proceeds from the offering, together with our existing cash, cash equivalents and marketable securities will be used (i) to advance the development of denifanstat and begin startup activities related to the pivotal Phase 3 program in metabolic dysfunction-associated steatohepatitis, or MASH, formerly known as nonalcoholic steatohepatitis, or NASH, including manufacturing of additional drug supply, (ii) to advance the development of TVB-3567 and submit an investigational new drug application for a Phase 1 clinical trial for the treatment of acne and (iii) for other general corporate purposes, including additional clinical development, working capital and operating expenses.

•

In January 2024, we announced positive topline results from our FASCINATE-2 Phase 2b clinical trial of denifanstat versus placebo in biopsy-confirmed MASH patients with stage 2 or stage 3 fibrosis (F2/F3) at week 52. Denifanstat met its primary and secondary endpoints, showing statistically significant improvements relative to placebo on both of the primary endpoints of MASH resolution without worsening of fibrosis with ≥2-point reduction in NAS (NAFLD Activity Score), and ≥2-point reduction in NAS without worsening of fibrosis. Denifanstat-treated patients also showed statistically significant fibrosis improvement by ≥ 1 stage with no worsening of MASH, and a greater proportion of MRI-derived proton density fat fraction (MRI-PDFF) ≥30% responders relative to placebo.

•

In July 2023, we closed an upsized initial public offering, or IPO, of Series A common stock, at a public offering price of $16.00 per share. Including shares issued pursuant to the exercise of the underwriters’ option, we issued 6,026,772 shares of Series A common stock, and received net proceeds of approximately $86.2 million.

•

Virtually attend the Annual Meeting at https://web.lumiconnect.com/217605655, using the password sagimet2024.

TABLE OF CONTENTS

Virtually attending the Annual Meeting will not by itself revoke a previously granted proxy.

If your shares are held by your broker, bank or other holder of record as a nominee or agent (i.e., the shares are held in street name), you should follow the instructions provided by your broker, bank or other holder of record.

Deadline for Voting. The deadline for voting by telephone or internet, other than by virtually attending the Annual Meeting, is 11:59 p.m. Eastern Time, or 8:59 p.m. Pacific Time, on June 4, 2024. If you are a registered stockholder and virtually attend the Annual Meeting, you may deliver your vote online during the Annual Meeting. “Street name” stockholders who wish to vote at the Annual Meeting will need to obtain a proxy form from the institution that holds their shares.

BROKER VOTING AND VOTES REQUIRED FOR EACH PROPOSAL

If your shares are held in a stock brokerage account or by a bank or other holder of record, you are considered the beneficial owner of shares held in street name. The Notice has been forwarded to you by your broker, bank or other holder of record who is considered the stockholder of record of those shares. As the beneficial owner, you may direct your broker, bank or other holder of record on how to vote your shares by using the proxy card included in the materials made available or by following their instructions for voting on the internet.

A broker non-vote occurs when a broker or other nominee that holds shares for another does not vote on a particular item because the nominee does not have discretionary voting authority for that item and has not received instructions from the beneficial owner of the shares. The following table summarizes how votes withheld, broker non-votes and abstentions are treated with respect to our proposals:

VOTING MATTERS	VOTES REQUIRED	TREATMENT OF ABSTENTIONS AND BROKER NON-VOTES	BROKER DISCRETIONARY VOTING
PROPOSAL 1: Election of Class I Directors for a Three-Year Term Expiring in 2027	Plurality of the votes properly cast	Votes withheld and broker non-votes will have no effect on the outcome of the proposal	No
PROPOSAL 2: Ratification of Appointment of Deloitte as our Independent Registered Public Accounting Firm for 2024	Majority of the votes properly cast	Abstentions and broker non-votes will have no effect on the outcome of the proposal	Yes

QUORUM

We must have a quorum to conduct business at the Annual Meeting. A quorum consists of the presence at the Annual Meeting, either attending the meeting virtually or represented by proxy, of the holders of shares of capital stock entitled to vote representing a majority of the voting power of all outstanding shares of capital stock entitled to vote. Holders of Series B common stock are not entitled to vote on any matters that will come before the Annual Meeting and therefore will not be considered for the purpose of determining the presence or absence of a quorum. For the purpose of establishing a quorum, votes withheld, abstentions, including brokers holding customers’ shares of record who cause abstentions to be recorded at the meeting, and broker non-votes count toward the quorum. If there is no quorum, the holders of shares of capital stock entitled to vote representing a majority of the voting power virtually attending the Annual Meeting or represented by proxy or the presiding officer of the meeting may adjourn the Annual Meeting to another date.

PROXY SOLICITATION COSTS

We pay the cost of soliciting proxies. Proxies will be solicited on behalf of the Board by mail, telephone, and other electronic means or in person. Directors and employees will not be paid any additional compensation for soliciting proxies. We may reimburse brokerage firms, banks and other agents for the cost of forwarding proxy materials to beneficial owners.

TABLE OF CONTENTS

BOARD OF DIRECTORS

Our Board has nominated Paul Hoelscher and Timothy P. Walbert for election as Class I directors at our Annual Meeting to hold office until our 2027 Annual Meeting.

Our Board consists of directors divided into three classes, with each class holding office for a three-year term. Each of Paul Hoelscher and Timothy P. Walbert, current Class I directors, have been nominated by our Board for election at the Annual Meeting for a three-year term that will expire at the 2027 Annual Meeting and until their successors, if any, are elected or appointed, or their earlier death, resignation, retirement, disqualification or removal. Each of the nominees has agreed to be named and to serve, and we expect each nominee to be able to serve if elected. If any nominee is unable to serve, the nominating and corporate governance committee of the Board, or the Nominating and Corporate Governance Committee, will recommend to our Board a replacement nominee. The Board may then designate the other nominee to stand for election. If you voted for the unavailable nominee, your vote will be cast for his or her replacement.

The number of members of our Board is currently set at nine members. We expanded the size of the Board from seven members to nine members on April 1, 2024 with the appointment of Timothy P. Walbert and Paul Hoelscher. The term of office of our Class I directors, Richard Rodgers, Jinzi Wu, Ph.D., Timothy P. Walbert and Paul Hoelscher, expires at the Annual Meeting. On March 20, 2024, Mr. Rodgers and Dr. Wu notified our Board that they would not stand for re-election at the Annual Meeting. As a result, each of Mr. Rodger’s and Dr. Wu’s service as a member of our Board will end effective as of the date of the Annual Meeting, and, after careful consideration, our Board has elected to reduce the size of the Board from nine to seven directors, effective as of the date of the Annual Meeting.

BOARD STRUCTURE AND COMPOSITION

Our business and affairs are managed under the direction of our Board, which currently consists of nine members. The primary responsibilities of our Board are to provide oversight, strategic guidance, counseling and direction to our management. Our Board meets on a regular basis and additionally as required. Our Eleventh Amended and Restated Certificate of Incorporation, or Charter, and Second Amended and Restated Bylaws, or Bylaws, permit our Board to establish the authorized number of directors from time to time by resolution. As described above, after careful consideration we have elected to reduce the size of our Board from nine to seven directors following the departure of Mr. Rodgers and Dr. Wu, effective as of the date of the Annual Meeting. Each director serves until the expiration of the term for which such director was elected or appointed, or until such director’s earlier death, resignation or removal. In accordance with our Charter, our Board is divided into three classes with staggered three-year terms. At each annual meeting of stockholders, the successors to directors whose terms then expire will be elected to serve from the time of election and qualification until the third annual meeting following election. Our directors are divided among the three classes as follows:

•

the Class I directors are Jinzi J. Wu, Ph.D., Richard Rodgers, Paul Hoelscher and Timothy P. Walbert and their terms will expire at the Annual Meeting (Dr. Wu and Mr. Rodgers will not stand for re-election at the Annual Meeting);

•

the Class II directors are Merdad Parsey, M.D., Ph.D., Elizabeth Grammer, Esq. and Beth Seidenberg, M.D. and their terms will expire at the annual meeting of stockholders to be held in 2025; and

•

the Class III directors are David Happel and George Kemble, Ph.D. and their terms will expire at the annual meeting of stockholders to be held in 2026.

Dr. Wu, Dr. Seidenberg, Dr. Kemble and Mr. Rodgers were elected to our Board pursuant to the Amended and Restated Voting Agreement we entered into in December 2020 with certain investors, or the Voting Agreement, which terminated upon the closing of our IPO.

On April 15, 2021, we entered into an Amended and Restated Nominating Agreement, as amended by Amendment No. 1 to Amended and Restated Nominating Agreement, entered into on June 22, 2023, or the BBA Funds Nominating Agreement, with Baker Brothers Life Sciences, L.P. and 667, L.P. (together, the BBA Funds). Pursuant to the BBA Funds Nominating Agreement, at any time at which the BBA Funds, together with their affiliates, collectively beneficially own (i) at least 1,449,543 shares of our Series A common

TABLE OF CONTENTS

stock and Series B common stock, and (ii) at least 2% of our then-outstanding voting common stock, we would have the obligation to support the nomination of, and to cause our Board to include in the slate of nominees recommended to our stockholders for election, one individual designated by the BBA Funds, or the Baker Designee, unless a majority of our disinterested directors reasonably and in good faith determines that a Baker Designee would not be qualified to serve as our director under law, rules of the Nasdaq Stock Market LLC, or Nasdaq, or other stock exchange on which our shares are listed, or our Bylaws. On December 21, 2023, the BBA Funds delivered a waiver to us under the BBA Funds Nominating Agreement, waiving such right to propose the nomination of the Baker Designee. During the Nominating Agreement term, if there is no Baker Designee on our Board, we will have the obligation to invite one Board observer designee of the BBA Funds, or the Baker Observer, to attend all meetings of our Board and all meetings of the committees of our Board as a nonvoting observer, subject to the Baker Observer’s agreement to hold in confidence the information they receive as observers of our Board and committee meetings, as well as subject to their exclusion from our Board meetings to preserve our attorney-client privilege, to avoid conflicts of interest, if the BBA Funds is determined by our Board to be a competitor, or other customary conditions. The BBA Funds Nominating Agreement automatically terminates upon the earliest of (i) such time when the BBA Funds together with their affiliates no longer beneficially own at least 1,449,543 shares of our Series A common stock and Series B common stock, (ii) July 18, 2026, or (iii) the consummation of a liquidation as such term is defined in our Charter.

CRITERIA FOR BOARD MEMBERSHIP

The Nominating and Corporate Governance Committee has identified certain criteria that it considers in identifying director nominees. Important general criteria and considerations for Board membership include:

GENERAL CRITERIA

✓

Relevant experience and expertise

✓

Proven achievement and competence in such individual’s field

✓

Sound business judgment

✓

An understanding of the fiduciary responsibilities required of a director willingness and ability to devote sufficient time to Board responsibilities

✓

Commitment to devoting time and energy to our affairs

✓

Diverse personal background, perspective and experience

The Nominating and Corporate Governance Committee also considers, on an ongoing basis, the background, experience and skills of the incumbent directors that are important to our current and future business needs and evaluates the experience and skills that would be valuable in new Board members.

SELECTION OF CANDIDATES

Director Skill Set Considerations

The Nominating and Corporate Governance Committee considers a wide range of factors including each director or candidate’s skill sets, other boards of directors on which he or she serves, other positions he or she holds, and the independence of each director and candidate, to ensure that a substantial majority of the Board is independent.

Potential Director Candidates

On an ongoing basis, the Nominating and Corporate Governance Committee considers potential director candidates identified on its own initiative, as well as candidates referred or recommended to it by other directors, members of management, search firms, stockholders and others (including individuals seeking to join the Board). Stockholders who wish to recommend candidates may contact the Nominating and

TABLE OF CONTENTS

Corporate Governance Committee in the manner described in “Stockholder Communications to the Board” in this Proxy Statement. Stockholder nominations must be made according to the procedures required under our Bylaws and described in this Proxy Statement under the heading “Requirements for Submission of Stockholder Proposals for Next Year’s Annual Meeting.” Stockholder-recommended candidates and stockholder nominees whose nominations comply with these procedures and who meet the criteria referred to above will be evaluated by the Nominating and Corporate Governance Committee in the same manner as the Board’s nominees.

BOARD DIVERSITY

Board diversity and inclusion is critical to our success. While we do not have a formal policy on Board diversity, the Board is committed to building a Board that consists of the optimal mix of skills, expertise, and diversity capable of effectively overseeing the execution of our business and meeting our evolving needs, with diversity reflecting gender, age, race, ethnicity, background, professional experience and perspectives. The Nominating and Corporate Governance Committee considers the value of diversity on the Board in evaluating director nominees. Accordingly, the Nominating and Corporate Governance Committee’s evaluation of director nominees includes consideration of their ability to contribute to the diversity of personal and professional experiences, opinions, perspectives and backgrounds on the Board.

As presently constituted, the Board represents a deliberate mix of members who have a deep understanding of our business who also have different skill sets and points of view. Our Board composition is in compliance with the listing requirements of Nasdaq, which mandate each listed company to have, or explain why it does not have, two diverse directors on the board, including at least one diverse director who self-identifies as female and at least one diverse director who self-identifies as an underrepresented minority or LGBTQ+, or for smaller reporting companies, two female directors.

The matrix below provides certain highlights of the composition of our Board members based on self-identification. Each term used above and in the matrix below has the meaning given to it in Nasdaq Listing Rule 5605(f).

Our Board believes that a strong culture of integrity, ethics and compliance is fundamental to the conduct of our business, and is necessary for effective risk management, maintaining investor trust, and successful corporate governance.

We understand corporate responsibility is essential for good governance because it strengthens the accountability of our Board and management team. We view Environmental, Social and Governance, or ESG, initiatives as long-term value drivers for the Company and our stockholders. Our focus on and commitment to ESG is tied to our belief that achieving and sustaining business excellence goes hand-in-hand with strong corporate leadership and stewardship. Our Board is primarily responsible for overseeing our corporate strategy, which includes the oversight of ESG matters that impact our business and related risks. Though our current ESG initiatives are broad, we continue to focus on our people, culture and strong corporate governance.

The following is a summary of our current ESG policies and practices:

•

Independent Committees: Each of our Board committees consists entirely of independent directors.

•

Regularly Held Executive Sessions: The independent directors of our Board meet separately in executive session on a regular basis to discuss matters relating to the Company and the Board, without members of the management team present.

•

Code of Conduct: All of our directors, officers and employees are subject to the Code of Conduct, which is available on our website at www.sagimet.com.

•

Human Capital Management: We are committed to the health and welfare of our employees. We support the development of our employees with a competitive compensation and benefits package, internal advancement, and individualized development opportunities.

•

Diversity and Inclusion: We strive to create a workplace culture that supports a diverse, multi-cultural workforce, treats individuals fairly, and provides an inclusive environment where everyone can bring their whole self to work and feel supported in reaching their full potential.

In each of the director nominee and continuing director biographies that follow, we highlight the specific experience, qualifications, attributes and skills that led the Board to conclude that the director nominee or continuing director should serve on our Board at this time.

TABLE OF CONTENTS

CORPORATE GOVERNANCE AND RISK MANAGEMENT

We are committed to good corporate governance and integrity in our business dealings. We believe that strong corporate governance practices that provide meaningful rights to our stockholders and ensure Board and management accountability are key to our relationship with our stockholders. We strive to have regular, constructive conversations with our stockholders to better understand our stockholders’ priorities and perspectives.

Our governance practices are documented in our Charter, our Bylaws, our Code of Conduct, our corporate governance guidelines, or the Corporate Governance Guidelines, and the charters of the committees of the Board, each of which is posted on our website at https://ir.sagimet.com/corporate-governance/governance-overview. Aspects of our governance documents are summarized below.

BOARD INDEPENDENCE

Under the listing standards, requirements and rules of Nasdaq, or the Nasdaq Listing Rules, independent directors must comprise a majority of our Board as a listed company within one year of the listing date. Our Board is currently comprised of a majority of independent directors.

Our Board has undertaken a review of the independence of each director. Based on information provided by each director concerning her or his background, employment and affiliations, including family relationships, our Board has determined that Dr. Seidenberg, Dr. Parsey, Ms. Grammer, Mr. Hoelscher, Mr. Rodgers and Mr. Walbert do not have relationships that would interfere with the exercise of independent judgment in carrying out the responsibilities of a director and that each of these directors is “independent” as that term is defined under the Nasdaq Listing Rules. Our Board has determined that each of Mr. Happel, by virtue of his position as our current Chief Executive Officer, Dr. Kemble, by virtue of his prior position as our former Chief Executive Officer, and Dr. Wu, by virtue of his executive officer role at Ascletis BioScience Co. Ltd., or Ascletis, our collaboration partner, are not independent under applicable rules and regulations of the SEC and the Nasdaq Listing Rules. In making these determinations, our Board considered the current and prior relationships that each non-employee director has with our Company and all other facts and circumstances our Board deemed relevant in determining their independence, including the beneficial ownership of our shares by each non-employee director and the transactions described in “Certain Relationships and Related Person Transactions.”

BOARD LEADERSHIP STRUCTURE AND THE BOARD’S ROLE IN RISK OVERSIGHT

Dr. Kemble is the current Executive Chairman of our Board and Mr. Happel is our current Chief Executive Officer, hence the roles of Executive Chairman and Chief Executive Officer are separated. We believe that separating these positions allows our Chief Executive Officer to focus on our day-to-day business, while allowing the Executive Chairman to lead the Board in its fundamental role of providing advice to and independent oversight of management. Our Board recognizes the time, effort and energy that the Chief Executive Officer is required to devote to his position in the current business environment, as well as the commitment required to serve as our Executive Chairman. While our Bylaws and Corporate Governance Guidelines do not require that our Executive Chairman and Chief Executive Officer positions be separate, our Board believes that having separate positions is the appropriate leadership structure for us at this time and demonstrates our commitment to good corporate governance.

Risk is inherent with every business, and how well a business manages risk can ultimately determine its success. Management is responsible for the day-to-day management of risks we face, while our Board, as a whole and through its committees, has responsibility for the oversight of risk management. In its risk oversight role, our Board 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 in overseeing the management of our risks is conducted primarily through committees of the Board, as disclosed in the descriptions of each of the committees below and in the charters of each of the committees. The full Board, 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 us, and the steps we take to manage them. When a Board committee is responsible

TABLE OF CONTENTS

for evaluating and overseeing the management of a particular risk and such risk is discussed at a Board committee meeting, the chairperson of the relevant committee reports on the discussion to the full Board during the committee report portion of the next Board meeting. This enables the Board and its committees to coordinate in risk oversight, particularly with respect to risk interrelationships.

BOARD COMMITTEES

Our Board has established an audit committee, or the Audit Committee, a compensation committee, or the Compensation Committee, and the Nominating and Corporate Governance Committee. The composition and responsibilities of each of the committees of our Board are described below. Members serve on these committees until their resignation or until otherwise determined by our Board. Each committee has adopted a written charter that satisfies the application rules and regulation of the SEC and the Nasdaq Listing Rules, which we have posted to our website at www.sagimet.com. Our Board may establish other committees as it deems necessary or appropriate from time to time.

EVALUATING BOARD EFFECTIVENESS

The Board, led by the Nominating and Corporate Governance Committee, is committed to continuous improvement and believes annual self-evaluations are an important tool for evaluating effectiveness. Beginning in 2024, our Board will conduct an annual self-evaluation of the Board, which will be presented by the Chairperson of the Nominating and Corporate Governance Committee to the Board for discussion. In addition, each committee will conduct an annual self-assessment in a review process similar to that used by the Board.

CODE OF BUSINESS CONDUCT AND ETHICS

We have adopted a written Code of Conduct that applies to all our employees, officers and directors. This includes our principal executive officer, principal financial officer and principal accounting officer or controller, or persons performing similar functions. The full text of our Code of Conduct is posted on our website at sagimet.com. We intend to disclose on our website any amendments of our Code of Conduct or waivers that exempt any principal executive officer, principal financial officer, principal accounting officer or controller, persons performing similar functions or our directors from provisions in the Code of Conduct.

DIRECTOR ORIENTATION AND CONTINUING EDUCATION

We familiarize new directors with the Company’s businesses, financial position, strategies, and policies, and assist them in developing the skills and knowledge required for their service on the Board. From time to time, management advises, or invites outside experts to attend Board meetings to advise, the Board on its responsibilities, management’s responsibilities, developments relevant to corporate governance and best corporate practices. Additionally, Board members may attend, and are encouraged to attend, accredited director education programs at our expense.

CORPORATE GOVERNANCE GUIDELINES

We have a written set of Corporate Governance Guidelines that are designed to help ensure effective corporate governance of our Company. Our Corporate Governance Guidelines cover topics including, but not limited to, the size and composition of the Board, Board membership criteria, director qualifications and duties, Board committees, director compensation and director communications with third parties. Succession planning for the Board is critical to our success. Our goal is to achieve a Board that provides effective oversight of the Company through the appropriate balance of diversity of perspectives, experience, expertise and skills. Our Corporate Governance Guidelines are reviewed periodically by the Nominating and Corporate Governance Committee, which will recommend any proposed changes to our Board for approval. Our Corporate Governance Guidelines can be found on our website at https://ir.sagimet.com/corporate-governance/governance-overview.

Under the policy, our non-employee directors are eligible to receive cash retainers (which will be payable quarterly in arrears and prorated for partial years of service) and equity awards as set forth below, provided that our non-employee directors may opt to receive their cash retainers in fully vested shares of our Series A common stock:

The Initial Grant and the Annual Grant are subject to full accelerated vesting upon the sale of the Company.

Narrative to the Summary Compensation Table

Our Compensation Committee reviews and approves compensation annually for all employees, including our named executive officers, with the exception of our Chief Executive Officer. The Compensation Committee reviews and recommends the Chief Executive Officer’s compensation to the Board for approval. In making compensation determinations, we consider compensation for comparable positions in the market, the historical compensation levels of our executives, individual performance as compared to our expectations and objectives, our desire to motivate our employees to achieve short- and long-term results that are in the best interests of our stockholders and a long-term commitment to our Company.

Annual Base Salary

Base salaries for our executive officers are initially established through arm’s-length negotiations at the time of the executive officer’s hiring, taking into account such executive officer’s qualifications, experience, the scope of his or her responsibilities and competitive market compensation paid by other companies for similar positions within the industry and geography. Base salaries are reviewed periodically, typically in connection with our annual performance review process, and adjusted from time to time to realign salaries with market levels after taking into account individual responsibilities, performance and experience. In making decisions regarding salary increases, we may also draw upon the experience of members of our Board with executives at other companies.

The 2023 annual base salaries in effect on January 1, 2023 for Mr. Happel, Dr. Kemble, Dr. Martins, and Mr. Hom were $470,000, $393,588, $414,000 and $360,360, respectively. The 2023 annual base salaries for Dr. Martins and Mr. Hom were increased on February 1, 2023 to $430,560 and $374,774, respectively. The 2023 annual base salaries for Mr. Happel, Dr. Kemble, and Dr. Martins were increased to $545,000, $489,000 and $451,000, respectively, following our IPO. Beginning in August 2023 and pursuant to the terms of his transition services agreement, from July 31, 2023 through September 15, 2023, Mr. Hom remained employed by us as a part-time, at-will employee and worked approximately eight hours per week and was paid $1,442 per week. See below for additional information regarding our transition services agreement with Mr. Hom.

TABLE OF CONTENTS

Performance Bonuses

During the year ended December 31, 2023, our named executive officers were each eligible to earn an annual bonus based on the achievement of certain individual objectives and company performance objectives. For the fiscal year ended December 31, 2023, the target annual bonuses for Mr. Happel and Dr. Martins were 55% and 40%, respectively. Dr. Kemble is not entitled to receive a cash bonus, but may receive cash incentive compensation as determined by the Board or Compensation Committee from time to time. Mr. Hom was not entitled to receive an annual bonus for 2023 pursuant to the terms of his separation agreement.

For 2023, all of our named executive officers were eligible to earn their annual bonus pursuant to the achievement of corporate and/or individual performance goals approved by our Board. These goals primarily related to the clinical development of denifanstat, the execution of our IPO, pipeline and platform development, financing and operations. The Board determined that the 2023 corporate goals were achieved at 110%. Following a review of 2023 performance, our Compensation Committee approved, and, in the case of Mr. Happel, our Compensation Committee recommended and our Board approved, 2023 annual bonus payouts to each of Mr. Happel and Dr. Martins equal to $329,725 and $202,840, respectively, in each case representing 110% of the target cash incentive for each such named executive officer.

Equity Compensation

We believe that equity awards provide our executive officers with a strong link to our long-term performance, create an ownership culture and help to align the interests of our executives and stockholders. In addition, we believe that equity awards with a time-based vesting feature promote executive retention because this feature incentivizes our executive officers to remain in our employment during the applicable vesting period. Accordingly, our Board periodically reviews the equity incentive compensation of our named executive officers and from time to time may grant equity incentive awards to them. In 2023, we granted options and restricted stock units to our named executive officers with the aggregate grant date fair values set forth in the 2023 summary compensation table above.

On April 20, 2023, we granted Dr. Martins an option to purchase 44,009 shares of our Series A common stock at an exercise price of $13.51 per share. The option vests in equal monthly installments over the course of 48 months, subject to Dr. Martin’s continued employment with us. Following our IPO, after an analysis and assessment of our executive compensation program and potential adjustments as a result of becoming a public company, on November 17, 2023, we granted restricted stock units to Mr. Happel, Dr. Martins and Dr. Kemble in the amounts of 624,910, 89,570 and 150,750, respectively. The restricted stock units will vest 25% on July 18, 2024, the first anniversary of our IPO, with the remaining 75% vesting in equal annual installments for the three years thereafter, subject to each executive’s continued employment with us through each such date. These awards are described in more detail in the “Outstanding equity awards as of December 31, 2023” table.

401(k) Plan

We maintain a defined contribution employee retirement plan (401(k) Plan) for our employees. The 401(k) Plan is intended to qualify as a tax-qualified plan under Section 401(a) of the Code. The 401(k) Plan covers all employees, including our named executive officers, who meet defined minimum age and service requirements and allows participants to defer a portion of their annual compensation on a pre-tax basis. The 401(k) Plan provides that each eligible participant may contribute up to the lesser of 100% of his or her compensation or the statutory limit. Participant contributions are held and invested, pursuant to the participant’s instructions, by the plan’s trustee. As a tax-qualified retirement plan, contributions to the 401(k) Plan are deductible by us when made, and contributions and earnings on those amounts are not generally taxable to the employees until withdrawn or distributed from the 401(k) Plan. We have not made any employer contributions to the 401(k) Plan as of the date of this proxy statement.

Nonqualified Deferred Compensation

We do not maintain nonqualified defined contribution plans or other nonqualified deferred compensation plans. Our Board may elect to provide our officers and other employees with nonqualified defined contribution or other nonqualified deferred compensation benefits in the future if it determines that doing so is in our best interests.

Employment Arrangements

We entered into new employment agreements with our named executive officers in connection in connection with our IPO providing for base salary, cash incentives, equity incentives, severance, and certain other benefits and payments. Below are descriptions of our executive employment agreements and other agreements with our named executive officers.

Mr. Happel. In October 2022, we entered into an offer letter with Mr. Happel, or the Happel Letter. The Happel Letter provided for at-will employment, an initial base salary of $470,000, a discretionary annual target bonus opportunity equal to 45% of base salary, eligibility for an initial stock option award to purchase 1,011,826 shares of our Series A common stock, and eligibility to receive an additional stock option grant upon the closing of a qualified financing to purchase that number of shares sufficient to bring Mr. Happel’s aggregate holdings up to 5% of our fully diluted shares at such time. Each option grant was subject to Board approval and has or will have an exercise price equal to the fair market value of our Series A common stock on the grant date. If Mr. Happel experienced a qualifying termination (as defined in the Happel Letter), he was entitled to (i) 12 months of salary continuation payments, and (ii) Consolidated Omnibus Budget Reconciliation Act, or COBRA, continuation coverage for up to 12 months. In addition, if Mr. Happel experienced a qualifying termination upon or within the 12-month period that immediately follows a change of control (as defined in the Happel Letter), then 100% of his initial stock option would have accelerated and would become fully vested as of the termination date. These severance and equity acceleration benefits were conditioned upon Mr. Happel continuing to comply with his obligations under the Happel Letter and his delivery of a general release of claims.

On August 15, 2023, we entered into an employment agreement with David Happel, which was effective as of July 19, 2023, or the Happel Employment Agreement, memorializing the terms of his continued employment as our Chief Executive Officer, and which supersedes the Happel Letter. The Happel Employment Agreement has an initial three-year term, subject to automatic renewal for additional one-year periods, unless either party gives written notice of termination to the other party and subject to earlier

termination in accordance with the terms of the Happel Employment Agreement. The payments and benefits to which Mr. Happel is entitled under the Happel Employment Agreement include: (i) an annual base salary of $545,000; (ii) a target annual bonus opportunity equal to 55% of base salary; and (iii) participation in our employee benefit plans that are generally available to our employees.

Pursuant to the Happel Employment Agreement, if we terminate Mr. Happel’s employment without “cause” or Mr. Happel resigns for “good reason” (each, as defined in the Happel Employment Agreement) outside of the Change in Control Period (as defined below), Mr. Happel will be entitled to the following severance benefits (in addition to certain accrued but unpaid amounts), subject to his execution of a general release of claims in favor of the Company: (i) a lump sum cash payment equal to 12 months of Mr. Happel’s base salary and (ii) the payment by us of premiums for up to 12 months of COBRA coverage substantially similar to that provided under our health plan, provided that Mr. Happel properly elects such coverage. In addition, pursuant to the terms of the Happel Employment Agreement, if we terminate Mr. Happel’s employment without “cause” or Mr. Happel resigns for “good reason” during the Change in Control Period, Mr. Happel will receive, subject to his execution of a general release of claims in favor of the Company, (i) a lump sum cash payment equal to 18 months of Mr. Happel’s base salary, (ii) a pro-rated portion of Mr. Happel’s target bonus for the year of termination (or, if higher, Mr. Happel’s target bonus in effect immediately prior to the “change in control” (as defined in the Happel Employment Agreement)), (iii) the payment by us of premiums for up to 18 months of COBRA coverage substantially similar to that provided under our health plan, provided that Mr. Happel properly elects such coverage, (iv) 100% vesting acceleration of all of Mr. Happel’s then-unvested equity awards (with any performance-based vesting deemed achieved and vested at target levels), and (v) an extension of the period of time (to a maximum of 12 months) following termination during which all of Mr. Happel’s outstanding stock option awards may be exercised, to the extent vested as of the date of termination (including any awards that accelerate and vest in connection with his termination). The “Change in Control Period” is the date of a “change in control” and ending 12 months following the date of such “change in control.”

Dr. Kemble. In October 2022, we entered into an amended and restated offer letter with Dr. Kemble, or the Kemble Letter. The Kemble Letter provided for at-will employment, provided, however, that Dr. Kemble serve in his role as Executive Chairman until the earliest of (i) the completion of the end of the Phase 2 meeting with the FDA for FASCINATE-2; (ii) the consummation of a change of control (as defined in the Kemble Letter), or (iii) the Board’s approval and execution of an employment agreement as Chief Scientific Officer (collectively, the Expected Events). The Kemble Letter provided an initial annual base salary of $393,588 and eligibility for an initial stock option to purchase 21,173 shares of our Series A common stock at an exercise price based on the fair market value of our Series A common stock on the grant date, subject to Board approval. The Kemble Letter also provided for a $40,000 annual payment to Dr. Kemble in respect of his services on our Board. If Dr. Kemble’s employment was terminated without cause (as defined in the Kemble Letter), excluding termination upon the occurrence of an Expected Event and other than as a result of his death or disability, then in addition to any amounts accrued and payable under the terms of our benefit plans through the date of termination, Dr. Kemble was entitled to (i) six months of salary continuation payments, and (ii) COBRA continuation coverage for up to six months. These severance benefits were conditioned upon Dr. Kemble’s delivery of a general release of claims, resignation, as applicable, from all positions, and delivery of all property and confidential information in Dr. Kemble’s possession, or the Severance Conditions. Further, if Dr. Kemble’s employment was terminated without cause or he was constructively terminated (as defined in the Kemble Letter) upon or within the 12-month period that immediately follows a change of control, in addition to the severance benefits provided above, 100% of all of his outstanding stock options and equity awards would have accelerated and would become fully vested as of the termination date, and any options would remain exercisable for a period of 12 months following such termination, subject to Dr. Kemble’s compliance with the Severance Conditions and his obligations under his proprietary information assignment agreement.

On August 15, 2023, we entered into an employment agreement with George Kemble, which was effective as of July 19, 2023, or the Kemble Employment Agreement, memorializing the terms of his continued employment as our Executive Chairman, and which supersedes the Kemble Letter. The Kemble Employment Agreement has an initial three-year term, subject to automatic renewal for additional one-year periods, unless either party gives written notice of nonrenewal to the other party and subject to earlier termination in accordance with the terms of the Kemble Employment Agreement. The payments and benefits

In addition, pursuant to the terms of the Kemble Employment Agreement, if we terminate Dr. Kemble’s employment without “cause” or Dr. Kemble resigns for “good reason” during the Change in Control Period, Dr. Kemble will receive, subject to his execution of a general release of claims in favor of the Company, (i) a lump sum cash payment equal to 12 months of Dr. Kemble’s base salary, (ii) the payment by us of premiums for up to 12 months of COBRA coverage substantially similar to that provided under our health plan, provided that Dr. Kemble properly elects such coverage, (iii) 100% vesting acceleration of all of Dr. Kemble’s then-unvested equity awards (with any performance-based vesting deemed achieved and vested at target levels), and (iv) an extension of the period of time (to a maximum of 12 months) following termination during which all of Dr. Kemble’s outstanding stock option awards may be exercised, to the extent vested as of the date of termination (including any awards that accelerate and vest in connection with his termination). The “Change in Control Period” is the date of a “change in control” (as defined in the Kemble Employment Agreement) and ending 12 months following the date of such “change in control.”

Dr. Martins. In February 2021, we entered into an offer letter with Dr. Martins, or the Martins Letter. The Martins Letter provided for at-will employment, an annual base salary of $400,000, a discretionary annual target bonus opportunity equal to 35% of base salary, and eligibility for an initial stock option grant to purchase 198,132 shares of our Series A common stock at an exercise price based on the fair market value of our Series A common stock on the grant date, subject to Board approval. If Dr. Martins experienced a qualifying termination (as defined in the Martins Letter), then in addition to any amounts accrued and payable under the terms of our benefit plans through the date of termination, Dr. Martins was entitled to (i) six months of salary continuation payments, and (ii) COBRA continuation coverage for up to six months. Further, if Dr. Martins experienced a qualifying termination (as defined in the Martins Letter) upon or within the 12-month period that immediately follows a change of control (as defined in the Martins Letter), then 100% of his initial stock option would have accelerated and would become fully vested as of the termination date. These severance and equity acceleration benefits were conditioned upon Dr. Martins continuing to comply with his obligations under the Martins Letter and his delivery of a general release of claims in favor of us.

On August 15, 2023, we entered into an employment agreement with Eduardo Martins, which was effective as of July 19, 2023, or the Martins Employment Agreement, memorializing the terms of his continued employment as our Chief Medical Officer, and which supersedes the Martins Letter. The Martins Employment Agreement has an initial three-year term, subject to automatic renewal for additional one-year periods, unless either party gives written notice of termination to the other party and subject to earlier termination in accordance with the terms of the Martins Employment Agreement. The payments and benefits to which Dr. Martins is entitled under the Martins Employment Agreement include: (i) an annual base salary of $461,000; (ii) a target annual bonus opportunity equal to 40% of base salary; and (iii) participation in our employee benefit plans that are generally available to Company employees.

Pursuant to the Martins Employment Agreement, if we terminate Dr. Martins’ employment without “cause” or Dr. Martins resigns for “good reason” (each, as defined in the Martins Employment Agreement) outside of the Change in Control Period (as defined below), Dr. Martins will be entitled to the following severance benefits (in addition to certain accrued but unpaid amounts), subject to his execution of a general release of claims in favor of the Company: (i) a lump sum cash payment equal to six months of Dr. Martins’ base salary and (ii) the payment by us of premiums for up to six months of COBRA coverage substantially

similar to that provided under our health plan, provided Dr. Martins properly elects such coverage. In addition, pursuant to the terms of the Martins Employment Agreement, if we terminate Dr. Martins’ employment without “cause” or Dr. Martins resigns for “good reason” during the Change in Control Period, Dr. Martins will receive, subject to his execution of a general release of claims in favor of the Company, (i) a lump sum cash payment equal to 12 months of Dr. Martins’ base salary, (ii) a pro-rated portion of Dr. Martins’ target bonus for the year of termination (or, if higher, Dr. Martins’ target bonus in effect immediately prior to the “change in control” (as defined in the Martins Employment Agreement)), (iii) the payment by us of premiums for up to 12 months of COBRA coverage substantially similar to that provided under our health plan, provided Dr. Martins properly elects such coverage, (iv) 100% vesting acceleration of all of Dr. Martins’ then-unvested equity awards (with any performance-based vesting deemed achieved and vested at target levels), and (v) an extension of the period of time (to a maximum of 12 months) following termination during which all of Dr. Martins’ outstanding stock option awards may be exercised, to the extent vested as of the date of termination (including any awards that accelerate and vest in connection with his termination). The “Change in Control Period” is the date of a “change in control” and ending 12 months following the date of such “change in control.”

Mr. Hom. In January 2019, we entered into an amended and restated employment agreement with Mr. Hom that governed the terms of Mr. Hom’s employment with us, or the Hom Agreement. The Hom Agreement provided for at-will employment, an initial annual base salary of $315,000, an annual target bonus opportunity equal to 30% of base salary, and eligibility for an initial stock option grant to purchase that number of shares that would represent 1.2% of our fully diluted shares following our Series E financing at an exercise price based on the fair market value of our Series A common stock on the grant date, subject to Board approval. If Mr. Hom’s employment terminated without cause (as defined in the Hom Agreement), and other than as a result of his death or disability, then in addition to any amounts accrued and payable under the terms of our benefit plans through the date of termination, Mr. Hom was entitled to (i) six months of salary continuation payments, and (ii) COBRA continuation coverage for up to six months. Further, if within the 12-month period that immediately follows a change of control (as defined in the Hom Agreement) Mr. Hom’s employment terminated without cause or he was constructively terminated (as defined in the Hom Agreement), then 100% of all of his outstanding stock options and equity awards would accelerate and become fully vested as of the termination date, and any options would remain exercisable for a period of 12 months following such termination. These severance and equity accelerations benefits were conditioned upon Mr. Hom’s delivery of a general release of claims, resignation from all positions, and delivery to us of all property and confidential information in Mr. Hom’s possession.

In April 2023, we entered into a transition services agreement with Mr. Hom, which was amended in June 2023. Pursuant to the terms of the transition services agreement, as amended, Mr. Hom served as our Chief Financial Officer until July 31, 2023. Following July 31, 2023 through September 15, 2023, Mr. Hom remained employed by us as a part-time, at-will employee and worked approximately eight hours per week and was paid $1,442 per week. Pursuant to the transition services agreement, we also paid for his COBRA premiums, and Mr. Hom received retention payments in the amount of $327,928. We also agreed to provide Mr. Hom with additional separation benefits beyond those he was entitled to in the Hom Agreement. Those additional benefits include accelerating Mr. Hom’s options to purchase our Series A common stock to the extent unvested on his termination date and extending the time period for him to exercise his vested options to the later of (i) 12 months following the termination of his employment, or (ii) September 15, 2024.

In September 2023, we entered into a separation agreement and release with Mr. Hom, pursuant to which his employment with the Company terminated effective September 15, 2023. In addition, pursuant to the separation agreement and release, Mr. Hom received (i) a one-time lump sum payment in the amount of $187,387, (ii) monthly payments by us of premiums for up to six months of COBRA coverage, (iii) accelerated vesting of Mr. Hom’s unvested stock options, and (iv) an extended time period for him to exercise his vested options to the later of 12 months following the termination of his employment, or September 15, 2024.

Equity Benefit Plans

2023 Stock Option and Incentive Plan

The 2023 Stock Option and Incentive Plan, or the 2023 Plan, was adopted by our Board on June 22, 2023, approved by our stockholders on July 4, 2023 and became effective on July 12, 2023. The 2023 Plan replaced the 2017 Plan. The 2023 Plan provides flexibility to our Compensation Committee to use various equity-based incentive awards as compensation tools to motivate our workforce.

We initially reserved 2,585,968 shares of Series A common stock for the issuance of awards under the 2023 Plan, or the Initial Limit. The 2023 Plan provides that the number of shares reserved and available for issuance under the 2023 Plan will automatically increase on January 1, 2024 and each January 1 thereafter, by 4% of the outstanding number of shares of our Series A common stock on the immediately preceding December 31, or such lesser number of shares as determined by our Compensation Committee, or the Annual Increase. On January 1, 2024, the number of shares of Series A common stock reserved for issuance under the 2023 Plan increased by 855,016 shares. The number of shares reserved under the 2023 Plan is subject to adjustment in the event of a stock split, stock dividend or other change in our capitalization.

The shares issuable under the 2023 Plan are and will be authorized but unissued shares or shares that we reacquire. The shares of Series A common stock underlying any awards under the 2023 Plan that are forfeited, cancelled, held back upon exercise or settlement of an award to satisfy the exercise price or tax withholding, reacquired by us prior to vesting, satisfied without the issuance of stock or are otherwise terminated (other than by exercise) will be added back to the shares of Series A common stock available for issuance under the 2023 Plan.

The maximum aggregate number of shares that may be issued in the form of incentive stock options shall not exceed the Initial Limit, cumulatively increased on January 1, 2024 and on each January 1 thereafter by the lesser of the Annual Increase for such year or shares of Series A common stock.

The grant date fair value of all awards made under the 2023 Plan and all other cash compensation paid by us to any non-employee director in any calendar year for services as a non-employee director shall not exceed $500,000; provided, however, that such amount shall be $750,000 for the calendar year in which the applicable non-employee director is initially elected or appointed to the Board.

The 2023 Plan is administered by our Compensation Committee. Our Compensation Committee has the full power to select, from among the individuals eligible for awards, the individuals to whom awards will be granted and the number of shares subject to such awards, to make any combination of awards to participants, to accelerate at any time the exercisability or vesting of any award, to impose any limitations and/or vesting conditions on each award and to determine the specific terms and conditions of each award, subject to the provisions of the 2023 Plan. Persons eligible to participate in the 2023 Plan are full or part-time officers, employees, non-employee directors and consultants as selected from time to time by our Compensation Committee in its discretion.

The 2023 Plan permits the granting of both options to purchase Series A common stock intended to qualify as incentive stock options under Section 422 of the Code and options that do not so qualify. The option exercise price of each option will be determined by our Compensation Committee but may not be less than 100% of the fair market value of our Series A common stock on the date of grant unless the option is granted (i) pursuant to a transaction described in, and in a manner consistent with, Section 424(a) of the Code or (ii) to individuals who are not subject to U.S. income tax. The term of each option will be fixed by our Compensation Committee and may not exceed ten years from the date of grant. Our Compensation Committee will determine at what time or times each option may be exercised.

TABLE OF CONTENTS

Our Compensation Committee may award stock appreciation rights subject to such conditions and restrictions as it may determine. Stock appreciation rights entitle the recipient to shares of Series A common stock, or cash, equal to the value of the appreciation in our stock price over the exercise price. The exercise price of each stock appreciation right may not be less than 100% of the fair market value of our Series A common stock on the date of grant unless the stock appreciation right is granted (i) pursuant to a transaction described in, and in a manner consistent with, Section 424(a) of the Code or (ii) to individuals who are not subject to U.S. income tax. The term of each stock appreciation right will be fixed by our Compensation Committee and may not exceed ten years from the date of grant. Our Compensation Committee will determine at what time or times each stock appreciation right may be exercised.

Our Compensation Committee may award restricted shares of Series A common stock and restricted stock units to participants subject to such conditions and restrictions as it may determine. These conditions and restrictions may include the achievement of certain performance goals and/or continued employment with us through a specified vesting period. Our Compensation Committee may also grant shares of Series A common stock that are free from any restrictions under the 2023 Plan. Unrestricted stock may be granted to participants in recognition of past services or for other valid consideration and may be issued in lieu of cash compensation due to such participant.

Our Compensation Committee may grant dividend equivalent rights to participants that entitle the recipient to receive credits for dividends that would be paid if the recipient had held a specified number of shares of our Series A common stock. Our Compensation Committee may grant cash bonuses under the 2023 Plan to participants, subject to the achievement of certain performance goals.

The 2023 Plan provides that upon the effectiveness of a “sale event,” as defined in the 2023 Plan, an acquirer or successor entity may assume, continue or substitute outstanding awards under the 2023 Plan. To the extent that awards granted under the 2023 Plan are not assumed or continued or substituted by the successor entity, upon the effective time of the sale event, such awards shall terminate. In such case, except as may be otherwise provided in the relevant award certificate, all awards with time-based vesting conditions or restrictions shall become fully vested and exercisable or nonforfeitable as of the effective time of the sale event, and all awards with conditions and restrictions relating to the attainment of performance goals may become vested and exercisable or nonforfeitable in connection with a sale event in the administrator’s discretion or to the extent specified in the relevant award certificate. In the event of such termination, individuals holding options and stock appreciation rights (i) may be permitted to exercise such options and stock appreciation rights (to the extent exercisable) within a specified period of time prior to the sale event or (ii) we may make or provide for a payment, in cash or in kind, to participants holding vested and exercisable options and stock appreciation rights equal to the difference between the per share consideration payable to stockholders in the sale event and the exercise price of the options or stock appreciation rights. In addition, we may make or provide for a payment, in cash or in kind, to participants holding other vested awards.

Our Board may amend or discontinue the 2023 Plan and our Compensation Committee may amend or cancel outstanding awards for purposes of satisfying changes in law or any other lawful purpose but no such action may adversely affect rights under an award without the holder’s consent. Certain amendments to the 2023 Plan require the approval of our stockholders. The administrator of the 2023 Plan is specifically authorized to exercise its discretion to reduce the exercise price of outstanding stock options and stock appreciation rights or effect the repricing of such awards through cancellation and re-grants without stockholder consent. No awards may be granted under the 2023 Plan after the date that is ten years from the effective date of the 2023 Plan.

2023 Employee Stock Purchase Plan

The 2023 Employee Stock Purchase Plan, or ESPP, was adopted by our Board on June 22, 2023, approved by our stockholders on July 4, 2023 and became effective on July 12, 2023. The ESPP is intended to qualify as an “employee stock purchase plan” within the meaning of Section 423 of the Code. The ESPP initially reserved and authorized the issuance of up to a total of 215,497 shares of Series A common stock to participating employees. The ESPP provides that the number of shares reserved and available for issuance will automatically increase on January 1, 2024 and each January 1 thereafter through January 1, 2033, by the least of (i) 215,497 shares of Series A common stock, (ii) 1% of the outstanding number of shares of our

TABLE OF CONTENTS

Series A common stock on the immediately preceding December 31 or (iii) such lesser number of shares of Series A common stock as determined by the administrator of the ESPP. On January 1, 2024, the number of shares of Series A common stock reserved for issuance under the ESPP increased by 213,754 shares. The number of shares reserved under the ESPP will be subject to adjustment in the event of a stock split, stock dividend or other change in our capitalization.

All employees are eligible to participate in the ESPP. However, any employee who owns 5% or more of the total combined voting power or value of all classes of stock will not be eligible to purchase shares under the ESPP.

We may make one or more offerings each year to our employees to purchase shares under the ESPP. Offerings will usually begin on each May 1 and November 1 and will continue for six-month periods, referred to as offering periods. Each eligible employee will be able to elect to participate in any offering by submitting an enrollment form at least 15 business days before the relevant offering date.

Each employee who is a participant in the ESPP will be able to purchase shares by authorizing payroll deductions of up to 15% of his or her eligible compensation during an offering period. Unless the participating employee has previously withdrawn from the offering, his or her accumulated payroll deductions will be used to purchase shares of Series A common stock on the last business day of the offering period at a price equal to 85% of the fair market value of the shares on the first business day or the last business day of the offering period, whichever is lower, provided that no more than a number of shares of Series A common stock determined by dividing $25,000 by the fair market value of the Series A common stock on the first day of the offering may be purchased by any one employee during any offering period. Under applicable tax rules, an employee may purchase no more than $25,000 worth of shares of Series A common stock, valued at the start of the purchase period, under the ESPP in any calendar year.

The accumulated payroll deductions of any employee who is not a participant on the last day of an offering period will be refunded. An employee’s rights under the ESPP will terminate upon voluntary withdrawal from the plan or when the employee ceases employment with us for any reason.

The ESPP may be terminated or amended by our Board at any time. An amendment that increases the number of shares of Series A common stock authorized under the ESPP and certain other amendments will require the approval of our stockholders.

2017 Equity Incentive Plan

Our Board adopted the 2017 Equity Incentive Plan, or 2017 Plan, in September 2017 and our stockholders approved the 2017 Plan in October 2017. The 2017 Plan was the successor to and continuation of the 2007 Plan. The 2017 Plan provided for the grant of incentive stock options, or ISOs, non-qualified stock options, or NSOs, stock appreciation rights, restricted stock awards, restricted stock unit awards and other awards to our employees, directors and consultants or our affiliates. ISOs may be granted only to our employees or employees of our affiliates. The 2017 Plan was terminated in July 2023. However, any outstanding awards granted under the 2017 Plan remain outstanding, subject to the terms of the 2017 Plan and award agreements, until such outstanding options are exercised or until any awards terminate or expire by their terms. In the event of a change in control, as defined under the 2017 Plan, awards granted under the 2017 Plan will not receive automatic acceleration of vesting and exercisability, although this treatment may be provided for in an award agreement.

Authorized Shares. As of September 30, 2023, options to purchase 3,702,976 shares of Series A common stock were outstanding under the 2017 Plan with a weighted-average exercise price of $7.80 per share.

Plan Administration. Our Board, or a duly authorized committee of our Board, administers the 2017 Plan and the awards granted under it. The administrator has the power to modify outstanding awards under the 2017 Plan. The administrator has the authority to reprice any outstanding option with the consent of any adversely affected participant.

Corporate Transactions. The 2017 Plan provides that in the event of certain specified significant corporate transactions, as defined under the 2017 Plan, our Board may (1) arrange for the assumption,

TABLE OF CONTENTS

continuation or substitution of an award by a successor corporation, or the acquiring corporation’s parent company; (2) arrange for the assignment of any reacquisition or repurchase rights held by us to a successor corporation, or the acquiring corporation’s parent company; (3) accelerate the vesting, in whole or in part, of the award and provide for its termination prior to the transaction if not exercised prior to the effective time of the corporate transaction; (4) arrange for the lapse, in whole or in part, of any reacquisition or repurchase rights held by us; (5) cancel or arrange for the cancellation of the award prior to the transaction in exchange for a cash payment, if any, determined by the Board; or (6) make a payment in such form as determined by the Board equal to the excess, if any, of the value of the property the participant would have received upon exercise of the awards prior to the transaction over any exercise price payable by the participant in connection with the exercise. The administrator is not obligated to treat all awards or portions of awards, even those that are of the same type, in the same manner.

Transferability. Our Board may impose limitations on the transferability of ISOs, NSOs and stock appreciation rights as the Board will determine. Absent such limitations, a participant may not transfer awards under the 2017 Plan other than by will, the laws of descent and distribution or as otherwise provided under the 2017 Plan.

2007 Equity Incentive Plan

Our Board adopted the 2007 Equity Incentive Plan, or the 2007 Plan, in December 2006, and our stockholders adopted the 2007 Plan in April 2007. The 2007 Plan provided for the grant of ISOs, NSOs and stock purchase rights, or restricted stock awards. ISOs were only granted to our employees or employees of our affiliates. The 2007 Plan was terminated in September 2017. However, any outstanding awards granted under the 2007 Plan remain outstanding, subject to the terms of the 2007 Plan and award agreements, until such outstanding options are exercised or until any awards terminate or expire by their terms.

Authorized Shares. As of September 30, 2023, options to purchase 63,529 shares of Series A common stock were outstanding under the 2007 Plan with a weighted-average exercise price of $19.61 per share.

Plan Administration. Our Board, or a duly authorized committee of our Board, administers the 2007 Plan and the awards granted under it. The administrator has the power to modify outstanding awards under the 2007 Plan. The administrator has the authority to determine whether to offer to buyout previously granted options and to determine the terms and conditions of such offer and buyout.

Acquisitions. The 2007 Plan provides that in the event of certain specified acquisitions, as defined under the 2007 Plan, our Board may arrange for the assumption or substitution of an award by a surviving corporation or entity, or the acquiring corporation or entity. In the event that an award is not assumed or substituted, then with respect to awards held by participants that did not terminate status as a service provider, the vesting for such awards will be accelerated and the awards will be made fully exercisable at least ten (10) days prior to the closing of the acquisition. Awards for all other participants shall be terminated if not exercised prior to the closing of the acquisition.

Transferability. A participant may not transfer awards under the 2007 Plan other than by will, the laws of descent and distribution or as otherwise provided under the 2007 Plan.

Senior Executive Cash Incentive Bonus Plan

On June 22, 2023, our Board adopted the Senior Executive Cash Incentive Bonus Plan, or the Bonus Plan. The Bonus Plan provides for cash bonus payments based upon company and individual performance targets established by our Compensation Committee. The payment targets are related to financial and operational measures or objectives with respect to our company, or one or more of the “Corporate Performance Goals” (as described below), as well as individual performance objectives.

Our Compensation Committee establishes the Corporate Performance Goals which may include the following: research, pre-clinical, non-clinical, developmental, publication, clinical or regulatory milestones; scientific or technological advances; research and development or manufacturing capabilities; cash flow (including, but not limited to, operating cash flow and free cash flow); revenue; corporate revenue; earnings before interest, taxes, depreciation and amortization; net income (loss) (either before or after interest, taxes, depreciation and/or amortization); changes in the market price of our Series A common stock;

TABLE OF CONTENTS

economic value-added; acquisitions, licenses, collaborations or strategic transactions; financing or other capital raising transactions; operating income (loss); return on capital, assets, equity, or investment; shareholder returns; return on sales; total shareholder return; gross or net profit levels; productivity; expense efficiency; margins; operating efficiency; satisfaction of, or other achievement metrics relating to, key third parties; working capital; earnings (loss) per share of our Series A common stock; bookings, new bookings or renewals; sales or market shares; number of prescriptions or prescribing physicians; coverage decisions; leadership development, employee retention, and recruiting and other human resources matters; operating income and/or net annual recurring revenue; or any other performance goal selected by the Compensation Committee, any of which may be measured in absolute terms, as compared to any incremental increase, in terms of growth, or as compared to results of a peer group, against the market as a whole, compared to applicable market indices and/or measured on a pre-tax or post-tax basis.

Each executive officer who is selected to participate in the Bonus Plan will have a target bonus opportunity set for each performance period and may also have a minimum and/or maximum bonus opportunity. The bonus formulas are adopted in each performance period by the Compensation Committee and communicated to each executive officer. The Corporate Performance Goals are measured at the end of each performance period after our financial reports have been published. If the Corporate Performance Goals and individual performance objectives are met, payments will be made as soon as practicable following the end of each performance period, but not later than 21∕2 months after the end of the fiscal year in which such performance period ends. Subject to the rights contained in any agreement between the executive officer and us, an executive officer shall be required to be employed by us on the bonus payment date to be eligible to receive a bonus payment.

Limitations on Liability and Indemnification

Our Charter contains provisions that limit the liability of our current and former directors for monetary damages to the fullest extent permitted by Delaware law. Delaware law provides that directors of a corporation will not be personally liable for monetary damages for any breach of fiduciary duties as directors, except liability for:

•

any breach of the director’s duty of loyalty to the corporation or its stockholders;

•

any act or omission not in good faith or that involves intentional misconduct or a knowing violation of law;

•

unlawful payments of dividends or unlawful stock repurchases or redemptions; or

•

any transaction from which the director derived an improper personal benefit.

Such limitation of liability does not apply to liabilities arising under federal securities laws and does not affect the availability of equitable remedies such as injunctive relief or rescission.

Our Charter authorizes us to indemnify our directors, officers, employees and other agents to the fullest extent permitted by Delaware law. Our Bylaws provide that we are required to indemnify our directors and officers to the fullest extent permitted by Delaware law and may indemnify our other employees and agents. Our Bylaws also provide that, on satisfaction of certain conditions, we will advance expenses incurred by a director or officer in advance of the final disposition of any action or proceeding, and permit us to secure insurance on behalf of any officer, director, employee, or other agent for any liability arising out of his or her actions in that capacity regardless of whether we would otherwise be permitted to indemnify him or her under the provisions of Delaware law. We have entered and expect to continue to enter into agreements to indemnify our directors, executive officers and other employees as determined by the Board. With certain exceptions, these agreements provide for indemnification for related expenses including attorneys’ fees, judgments, fines and settlement amounts incurred by any of these individuals in any action or proceeding.

We believe that our Charter and Bylaws provisions and indemnification agreements are necessary to attract and retain qualified persons as directors and officers. We also maintain customary directors’ and officers’ liability insurance.

TABLE OF CONTENTS

The limitation of liability and indemnification provisions in our Charter and Bylaws may discourage stockholders from bringing a lawsuit against our directors for breach of their fiduciary duty. They may also reduce the likelihood of derivative litigation against our directors and officers, even though an action, if successful, might benefit us and other stockholders. Further, a stockholder’s investment may be adversely affected to the extent that we pay the costs of settlement and damage awards against directors and officers as required by these indemnification provisions.

Insofar as indemnification for liabilities arising under the Securities Act may be permitted for directors, executive officers, or persons controlling us, we have been informed that, in the opinion of the SEC, such indemnification is against public policy as expressed in the Securities Act and is therefore unenforceable.

Rule 10b5-1 Plans

We maintain a Rule 10b5-1 Policy, under which our directors, executive officers and employees may adopt written plans, known as Rule 10b5-1 plans, in which they will contract with a broker to buy or sell shares of our Series A common stock on a periodic basis. Under a Rule 10b5-1 plan, a broker executes trades under parameters established by the director or officer when entering into the plan, without further direction from them. The director or officer may amend a Rule 10b5-1 plan in some circumstances and may terminate a plan at any time. Our directors and executive officers may also buy or sell additional shares outside of a Rule 10b5-1 plan when they do not possess material nonpublic information, subject to compliance with the terms of our insider trading policy.

Compensation Recovery Policy

Our Board has adopted a Compensation Recovery Policy, or the Clawback Policy, applicable to all officers subject to Section 16 of the Exchange Act. Under the Clawback Policy, we will pursue recoupment of any excess compensation, which was awarded to a covered officer based on financial statements of the Company where such statements are required to be restated. In addition to recoupment of any excess compensation, we will seek to recoup up to 100% of all incentive-based compensation in the case of (i) willful, knowing or intentional misconduct or a willful, knowing or intentional violation of any of our rules or applicable legal or regulatory requirements or (ii) fraud in the course of a covered employee’s employment. The recovery period for recoupment of any compensation is up to three fiscal years preceding the date on which we determine we are required to prepare and file the restated financial statements. This policy has been adopted to comply with the final guidance under Section 954 of the Dodd-Frank Wall Street Reform and Consumer Protection Act of 2010, or the Dodd-Frank Act.

CERTAIN RELATIONSHIPS AND RELATED PARTY TRANSACTIONS

Below we describe transactions since January 1, 2022 and each currently proposed transaction in which:

•

the amounts involved exceeded or will exceeds the lesser of $120,000 or 1% of our total assets at the year-end for the last two completed fiscal years; and

BBA Funds Nominating Agreement

Policies and Procedures for Transactions with Related Persons

We have adopted a written policy that our executive officers, directors, nominees for election as a director, beneficial owners of more than 5% of any series of our Series A common stock and any members of the immediate family of any of the foregoing persons are not permitted to enter into a related person transaction with us without the approval or ratification of our Board or our Audit Committee.

In approving or rejecting any such proposal, our Board or our Audit Committee is to consider the material facts of the transaction, including whether the transaction is on terms no less favorable than terms generally available to an unaffiliated third party under the same or similar circumstances and the extent of the related person’s interest in the transaction.

As of December 31, 2023, (i) 1,453,558 shares remained available for future issuance under our 2023 Plan, (ii) and 215,497 shares remained available for future issuance under our ESPP (as of December 31, 2023 we have not commenced any purchase periods associated with our ESPP). No shares remained available for future issuance under the 2007 Plan or 2017 Plan as of December 31, 2023. However, the 2007 Plan and 2017 Plan continue to govern outstanding equity awards granted thereunder. Our 2023 Plan has an evergreen provision that allows for an annual increase in the number of shares available for issuance under the 2023 Plan to be added on the first day of January, starting with January 1, 2024, in an amount equal to the lesser of (i) 4% of the outstanding number of shares of our Series A common stock on the immediately preceding December 31 or (ii) such number of shares as determined by our Compensation Committee in each case subject to adjustment in the event of a stock split, stock dividend or other change in our capitalization.

Inducement grants to new employees are determined on a case-by-case basis. Other than inducement grants, we expect that all equity awards will be made under shareholder-approved plans.

SECURITY OWNERSHIP OF CERTAIN BENEFICIAL OWNERS AND MANAGEMENT

The following table sets forth certain information regarding the beneficial ownership of Series A common stock as of April 10, 2024 by (a) each person known by us to be the beneficial owner of more than 5% of the outstanding shares of Series A common stock, (b) each named executive officer identified in the “Summary Compensation Table” above, (c) each director and nominee for director, and (d) all executive officers and directors as a group.

We have determined beneficial ownership in accordance with the rules and regulations of the SEC, and the information is not necessarily indicative of beneficial ownership for any other purpose. Except as indicated by the footnotes below, we believe, based on information furnished to us, that the persons and entities named in the table below have sole voting and sole investment power with respect to all shares that they beneficially own, subject to applicable community property laws.

The following table excludes our non-voting Series B common stock. Entities associated with Baker Brothers Life Sciences, L.P., or Baker Brothers, hold all 1,520,490 outstanding shares of Series B common stock. Baker Brothers has the right to convert each share of Series B common stock into one share of Series A common stock at such its election, provided that as a result of such conversion, Baker Brothers would not beneficially own in excess of 4.99% of any series of our securities registered under the Exchange Act, except as expressly provided for in Charter.

The percentage of Series A common stock outstanding is based on 30,393,397 shares of Series A common stock outstanding as of April 10, 2024.

In computing the number of shares beneficially owned by a person and the percentage ownership of such person, we deemed to be outstanding all shares subject to options held by the person that are currently exercisable, or exercisable within 60 days of January 1, 2024. However, except as described above, we did not deem such shares outstanding for the purpose of computing the percentage ownership of any other person.

Unless otherwise indicated, the address for each beneficial owner listed in the table below is c/o Sagimet Biosciences Inc., 155 Bovet Road, Suite 303, San Mateo, California 94402.

PROPOSAL 2: RATIFICATION OF APPOINTMENT OF DELOITTE & TOUCHE LLP AS OUR INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM FOR 2024

The Audit Committee of the Board has appointed and engaged Deloitte to serve as our independent registered public accounting firm to audit the consolidated financial statements of the Company and our subsidiary for the 2024 fiscal year, and to perform audit-related services. Deloitte has served as our independent registered public accounting firm since 2015.

Stockholders are hereby asked to ratify the Audit Committee’s appointment of Deloitte as our independent registered public accounting firm for the 2024 fiscal year.

The Audit Committee is solely responsible for selecting our independent auditors. Although stockholder ratification of the appointment of Deloitte to serve as our independent registered public accounting firm is not required by law or our organizational documents, the Board has determined that it is desirable to seek stockholder ratification as a matter of good corporate governance in view of the critical role played by independent registered public accounting firms in maintaining the integrity of financial controls and reporting. If the stockholders do not ratify the appointment of Deloitte, the Audit Committee will reconsider its selection and whether to engage an alternative independent registered public accounting firm.

Representatives of Deloitte are expected to virtually attend the Annual Meeting where they will be available to respond to appropriate questions and, if they desire, to make a statement.

THE BOARD UNANIMOUSLY RECOMMENDS A VOTE FOR THE RATIFICATION OF DELOITTE & TOUCHE LLP AS INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM FOR THE COMPANY FOR THE FISCAL YEAR ENDING DECEMBER 31, 2024.
