ArriVent BioPharma, Inc. 10-K

Item 9A. Controls and Procedures Evaluation of Disclosure Controls and Procedures Our management maintains disclosure controls and procedures that are designed to ensure that information required to be disclosed in our periodic and current reports that we file with the SEC is recorded, processed, summarized and reported within the time periods specified in the SEC’s rules and forms, and that such information is accumulated and communicated to our management, including our principal executive officer and principal financial officer, as appropriate, to allow timely decisions regarding required disclosure. Management recognizes that any controls and procedures, no matter how well designed and operated, can provide only reasonable assurance of achieving their objectives, and management necessarily applies its judgment in evaluating the cost-benefit relationship of possible controls and procedures. Our management, with the participation of our Chief Executive Officer and Chief Financial Officer, has evaluated the effectiveness of our disclosure controls and procedures (as such term is defined in Rules 13a-15(e) and 15d-15(e) under the Exchange Act) as of December 31, 2023. As of December 31, 2023, our disclosure controls and procedures were not effective as a result of our material weaknesses in our internal control over financial reporting. However, our management, including our Chief Executive Officer and our Chief Financial Officer, has concluded that, notwithstanding the identified material weaknesses in our internal control over financial reporting, the financial statements in this Annual Report on Form 10-K fairly present, in all material respects, our financial position, results of operations and cash flows for the periods presented in conformity with U.S. GAAP. Inherent Limitations over Internal Controls ​ Our management is responsible for establishing and maintaining adequate internal control over financial reporting. Internal control over financial reporting is defined in Rules 13a-15(f) and 15d-15(f) under the Exchange Act as a process designed by, or under the supervision of, a company’s principal executive officer and principal financial officer, or persons performing similar functions, and effected by a company’s board of directors, management, and other personnel, to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles and includes those policies and procedures that: ​ ● pertain to the maintenance of records that in reasonable detail accurately and fairly reflect the transactions and dispositions of a company’s assets; ​ ● provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that a company’s receipts and expenditures are being made only in accordance with authorizations of the company’s management and directors; and ​ ● provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use or disposition of our assets that could have a material effect on the financial statements. ​ Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate. 140 Table of Contents As described in Item 1A. “Risk Factors,” as of December 31, 2023, we have material weaknesses in our internal control over financial reporting relating to insufficient accounting resources which resulted in the following ineffective risk assessment activities: (a) We did not effectively design and implement controls related to the review and approval of manual journal entries. (b) We had ineffectively designed process-level controls associated with accounting for certain non-routine transactions. Management’s Report on Internal Control Over Financial Reporting ​ This Annual Report does not include a report of management’s assessment regarding internal control over financial reporting due to a transition period established by rules of the SEC for newly public companies. Attestation Report of the Registered Public Accounting Firm ​ This Annual Report does not include an attestation report of our registered public accounting firm due to a transition period established by rules of the SEC for newly public companies. Additionally, our independent registered public accounting firm will not be required to opine on our internal control over financial reporting until we are no longer an emerging growth company. Changes in Internal Control Over Financial Reporting ​ Other than the material weakness remediation activities described below, there were no changes in our internal control over financial reporting, as identified in connection with evaluation required by Rules 13a-15(e) and 15d-15(e) under the Exchange Act, that occurred during the year ended December 31, 2023 that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting. ​ During the year ended December 31, 2023, we have taken steps of implementing our remediation plans with respect to the material weaknesses identified in our internal control over financial reporting. Specifically, with the oversight of senior management and our audit committee, we have hired our Chief Financial Officer, and begun implementing processes and controls to address the material weaknesses. We have increased the number of resources (internal and third-party) dedicated to our accounting and finance team, including personnel with additional knowledge, experience, and training, to ensure we have adequate staff, to segregate key duties, and to comply with company policies and procedures. We also plan to engage a third-party provider to help us assess and improve our internal controls in preparation for compliance with the Sarbanes-Oxley Act. Additionally, we continue to make progress on implementing written policies and implementing process level and management review controls for our manual journal entries. However, we cannot assure you that we will be successful in remediating the material weaknesses we identified or that our internal control over financial reporting, as modified, will enable us to identify or avoid material weaknesses in the future. While we believe that these efforts will improve our internal control over financial reporting in accordance with U.S. GAAP and SEC reporting requirements, the implementation of these measures is ongoing and will require validation and testing of the design and operating effectiveness of internal controls over a sustained period of financial reporting cycles. The material weaknesses will not be considered remediated until our management designs and implements effective controls that operate for a sufficient period of time and our management has concluded through testing that these controls are effective. We cannot assure you that the measures we have taken to date, and are continuing to implement, will be sufficient to establish and maintain effective internal control over financial reporting. ​ 141 Table of Contents Item 9B. Other Information On March 27, 2024, Dr. Jallal notified our board of directors of her decision to resign from our board of directors and the compensation committee and the nominating and corporate governance committee, effective March 28, 2024. Dr. Jallal’s decision to resign was not due to any disagreement with the Company on any matter relating to the Company’s operations, policies or practices. ​ On March 28, 2024, we notified the Nasdaq Stock Market (“Nasdaq”) of Dr. Jallal’s resignation from the board of directors and that because such resignation, the compensation committee (the “Compensation Committee”) of our board of directors will have only one member, and the registrant will no longer comply with Nasdaq Listing Rule 5605(d)(2), which requires companies with securities listed on Nasdaq to have a compensation committee composed of at least two directors. In accordance with Nasdaq Listing Rule 5605(d)(4), we have an automatic cure period in order to regain compliance. We expect to regain compliance with such rule by filling the vacancy on the Compensation Committee caused by Dr. Jallal’s resignation with an independent director who satisfies the applicable requirements of the Nasdaq Listing Rules prior to the expiration of the cure period provided under Nasdaq Listing Rule 5605. Rule 10b5-1 Trading Plans During the fiscal quarter ended December 31, 2023, none of our directors or executive officers adopted, modified or terminated any contract, instruction or written plan for the purchase or sale of our securities that was intended to satisfy the affirmative defense conditions of Rule 10b5-1(c) or any “non-Rule 10b5-1 trading arrangement” as defined in Item 408(c) of Regulation S-K. ​ ​ Item 9C.

Board Composition Our board of directors consists of six members with one vacancy. All of our directors are members pursuant to the board composition provisions of our amended and restated certificate of incorporation and amended and restated bylaws. Our nominating and corporate governance committee and our board of directors may therefore consider a broad range of factors relating to the qualifications and background of nominees, which may include diversity, which is not only limited to race, gender or national origin. We have no formal policy regarding board diversity. Our nominating and corporate governance committee’s and board of directors’ priority in selecting board members is identification of persons who will further the interests of our stockholders through his or her established record of professional accomplishment, the ability to contribute positively to the collaborative culture among board members, knowledge of our business, understanding of the competitive landscape and professional and personal experiences and expertise relevant to our growth strategy. Our directors hold office until their successors have been elected and qualified or until the earlier of their death, resignation or removal. Our amended and restated certificate of incorporation and amended and restated bylaws provide that our directors may be removed only for cause by the affirmative vote of the holders of at least 75% of the votes that all our stockholders would be entitled to cast in an annual election of directors, and that any vacancy on our board of directors, including a vacancy resulting from an enlargement of our board of directors, may be filled only by vote of a majority of our directors then in office. Director Independence Our common stock is listed on the Nasdaq Global Market. Under the Nasdaq listing rules, independent directors must comprise a majority of a listed company’s board of directors within 12 months from the date of listing. In addition, 145 Table of Contents the Nasdaq listing rules require that, subject to specified exceptions, each member of a listed company’s audit, compensation and nominating and corporate governance committees be independent within 12 months from the date of listing. Audit committee members must also satisfy additional independence criteria, including those set forth in Rule 10A-3 under the Exchange Act, and compensation committee members must also satisfy the independence criteria set forth in Rule 10C-1 under the Exchange Act. Pursuant to Rule 10A-3, a minority of a company’s audit committee may be comprised of non-independent directors for a period of up to one year after becoming subject to Rule 10A-3 under the Exchange Act. Under Nasdaq listing rules, a director will only qualify as an “independent director” if, in the opinion of that company’s board of directors, that person does not have a relationship that would interfere with the exercise of independent judgment in carrying out the responsibilities of a director. In order to be considered independent for purposes of Rule 10A-3 under the Exchange Act, a member of an audit committee of a listed company may not, other than in his or her capacity as a member of the audit committee, the board of directors, or any other board committee: (1) accept, directly or indirectly, any consulting, advisory, or other compensatory fee from the listed company or any of its subsidiaries, other than compensation for board service; or (2) be an affiliated person of the listed company or any of its subsidiaries. In order to be considered independent for purposes of Rule 10C-1, the board of directors must consider, for each member of a compensation committee of a listed company, all factors specifically relevant to determining whether a director has a relationship to such company which is material to that director’s ability to be independent from management in connection with the duties of a compensation committee member, including, but not limited to: the source of compensation of the director, including any consulting advisory or other compensatory fee paid by such company to the director, and whether the director is affiliated with the company or any of its subsidiaries or affiliates. Our board of directors has determined that all members of our board of directors, except Carl L. Gordon, Ph.D., CFA, only with respect to the requirements of Rule 10A-3 under the Exchange Act, and Zhengbin (Bing) Yao, Ph.D. and Stuart Lutzker, M.D., Ph.D. are independent directors, including for purposes of the rules of Nasdaq and relevant federal securities laws and regulations. In making such independence determinations, our board of directors considered the relationships that each nonemployee director has with us and all other facts and circumstances that our 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. Zhengbin (Bing) Yao, Ph.D. and Stuart Lutzker, M.D., Ph.D. are not independent directors under these rules because each is an executive officer. Classified Board In accordance with the terms of our amended and restated certificate of incorporation and amended and restated bylaws, our board of directors are divided into three staggered classes of directors. At each annual meeting of the stockholders, a class of directors will be elected for a three-year term to succeed the directors of the same class whose terms are then expiring. The terms of the directors will expire upon the election and qualification of successor directors at the annual meeting of stockholders to be held during the years 2025 for Class I directors, 2026 for Class II directors and 2027 for Class III directors: ● our Class I director is Carl L. Gordon, Ph.D., CFA; ● our Class II directors are James Healy, M.D., Ph.D. and Stuart Lutzker, M.D., Ph.D.; and ● our Class III directors are Zhengbin (Bing) Yao, Ph.D., Bahija Jallal, Ph.D. and Chris W. Nolet. Our amended and restated certificate of incorporation and amended and restated bylaws provide that the number of our directors shall be fixed from time to time by a resolution of the majority of our board of directors. Any additional directorships resulting from an increase in the number of directors will be distributed among the three classes. The division of our board of directors into three classes with staggered three-year terms may delay or prevent stockholder efforts to effect a change of our management or a change in control. 146 Table of Contents Committees of the Board of Directors and Meetings Our board of directors has established an audit committee, a compensation committee and a nominating and corporate governance committee, each of which operates pursuant to a charter adopted by our board of directors. The board of directors may also establish other committees from time to time to assist us and our board of directors. The composition and functioning of all of our committees complies with all applicable requirements of the Sarbanes-Oxley Act of 2002, Nasdaq and SEC rules and regulations, subject to any applicable transition or phase-in periods.

Gordon, Ph.D., CFA, James Healy, M.D., Ph.D., and Chris W. Nolet, with Mr. Nolet serving as chair of the committee.

Although our board of directors has determined that Dr. Gordon is an “independent director” as defined under the applicable Nasdaq listing rules, it has also determined that he does not meet the additional requirements of independence applicable to audit committee members of a listed issuer under Rule 10A-3 under the Exchange Act because he is a founding member and Managing Partner and Co-Head of Global Private Equity of OrbiMed Advisors LLC, which indirectly owns one of our stockholders that beneficially holds greater than 10% of our stock. However, our board of directors determined that it was in our best interest to appoint Dr. Gordon to the audit committee due to his scientific expertise, extensive business experience, and experience in venture capital and the life sciences industry. Our board of directors has determined that Mr. Nolet is an “audit committee financial expert” within the meaning of the SEC regulations and the applicable rules of Nasdaq. The audit committee’s responsibilities include: ● selecting a firm to serve as the independent registered public accounting firm to audit our financial statements; ● ensuring the independence of the independent registered public accounting firm; ● discussing the scope and results of the audit with the independent registered public accounting firm, and reviewing, with management and that firm, our interim and year-end operating results; ● establishing procedures for employees to anonymously submit concerns about questionable accounting or audit matters; ● considering the effectiveness of our internal controls and internal audit function; ● reviewing material related-party transactions or those that require disclosure; and ● approving or, as permitted, pre-approving all audit and non-audit services to be performed by the independent registered public accounting firm.

Each member of this committee is a non-employee director, as defined by Rule 16b-3 promulgated under the Exchange Act, and an outside director, as defined pursuant to Section 162(m) of the Internal Revenue Code of 1986, as amended. Our board of directors has determined that each member of the compensation committee is “independent” as defined in the rules of Nasdaq. The composition of our compensation committee meets the requirements for independence under 147 Table of Contents the listing standards of Nasdaq, including the applicable transition rules. Our compensation committee is comprised of only directors that are independent under the rules of Nasdaq. The compensation committee’s responsibilities include: ● annually reviewing and recommending to the board of directors the corporate goals and objectives relevant to the compensation of our Chief Executive Officer; ● evaluating the performance of our Chief Executive Officer in light of such corporate goals and objectives and, based on such evaluation, recommending to the board of directors the cash compensation of our Chief Executive Officer; ● reviewing and approving, or recommending that our board of directors approve, the compensation of our executive officers; ● reviewing and recommending to our board of directors the compensation of our directors; ● reviewing and recommending to our board of directors the terms of any compensatory agreements with our executive officers; ● administering our stock and equity incentive plans; ● reviewing and approving, or making recommendations to our board of directors with respect to, incentive compensation and equity plans; ● reviewing and approving the retention or termination of any consulting firm or outside advisor to assist in the evaluation of compensation matters and evaluating and assessing potential and current compensation advisors in accordance with the independence standards identified in the applicable Nasdaq rules; ● retaining and approving the compensation of any compensation advisors; ● preparing the compensation committee report required by SEC rules, if and when required, to be included in our annual proxy statement; and ● reviewing all overall compensation policies and practices. Nominating and Corporate Governance Committee Our nominating and corporate governance committee did not meet during our fiscal year ended December 31, 2023. Our nominating and corporate governance committee is comprised of James Healy, M.D., Ph.D. and Bahija Jallal, Ph.D., with Dr. Healy serving as chair of the committee.

Meeting Attendance During our fiscal year ended December 31, 2023, there were five (5) meetings of our board of directors, and the various committees of our board of directors met a total of five (5) times. No director attended fewer than 75% of the total number of meetings of our board of directors and of committees of our board of directors on which he or she served 148 Table of Contents during fiscal 2023, except for Bahija Jallal, Ph.D., who attended five (5) of the applicable seven (7) meetings of the board and committees of the board on which she served that were held during 2023. Our board of directors has adopted a policy under which each member of our board of directors is strongly encouraged but not required to attend each annual meeting of our stockholders. Leadership Structure and Risk Oversight Our board of directors is currently chaired by Zhengbin (Bing) Yao, Ph.D., who also serves as our Chief Executive Officer. Our board of directors does not have a policy regarding the separation of the roles of Chief Executive Officer and Chairman of the board of directors, as our board of directors believes it is in our best interest to make that determination based on our position and direction and the membership of the board of directors. Our board of directors has determined that having an employee director serve as Chairman is in the best interest of our stockholders at this time because of the efficiencies achieved in having the role of Chief Executive Officer and Chairman combined, and because the detailed knowledge of our day-to-day operations and business that the Chief Executive Officer possesses greatly enhances the decision-making processes of our board of directors as a whole. We have a governance structure in place, including independent directors, designed to ensure the powers and duties of the dual role are handled responsibly. We do not have a lead independent director. Our board of directors oversees the management of risks inherent in the operation of our business and the implementation of our business strategies. Our board of directors performs this oversight role by using several different levels of review. In connection with its reviews of our operations and corporate functions, our board of directors addresses the primary risks associated with those operations and corporate functions. In addition, our board of directors reviews the risks associated with our business strategies periodically throughout the year as part of its consideration of undertaking any such business strategies. Each of our board committees also oversees the management of our risks that fall within the committee’s areas of responsibility. In performing this function, each committee has full access to management, as well as the ability to engage advisors. Our Chief Executive Officer reports to the audit committee and is responsible for identifying, evaluating and implementing risk management controls and methodologies to address any identified risks. In connection with its risk management role, our audit committee meets privately with representatives from our independent registered public accounting firm and our Chief Executive Officer. The audit committee oversees the operation of our risk management program, including the identification of the primary risks associated with our business and periodic updates to such risks, and reports to our board of directors regarding these activities. Compensation Committee Interlocks and Insider Participation None of the members of our compensation committee has at any time during the last fiscal year been one of our officers or employees. None of our executive officers currently serves, or in the past fiscal year has served, as a member of the board of directors or compensation committee of any entity that has one or more executive officers serving on our board of directors or compensation committee. For a description of transactions between us and members of our compensation committee and affiliates of such members, please see the “Certain Relationships and Related Transactions, and Director Independence” section of this Annual Report. Board Diversity We believe that our board of directors should be diverse, including a diversity of experience, competency in relevant fields, gender, race, ethnicity and age. In making determinations regarding nominations of directors, our nominating and corporate governance committee takes into account the benefits of diverse viewpoints. Our nominating and corporate governance committee will also consider these and other factors as it oversees the annual board of directors and committee evaluations. ​ 149 Table of Contents The table below provides certain information regarding the diversity of our board of directors: Board Diversity Matrix (As of March 22, 2024) Board Size: Total Number of Directors 6 Female Male Non-Binary Did not Disclose Gender Gender Identity: Directors 1 4 — 1 Number of Directors Who Identify in Any of the Categories Below: African American or Black — — — — Alaskan Native or Native American — — — — Asian — 1 — — Hispanic or Latinx — — — — Native Hawaiian or Pacific Islander — — — — White — 2 — — Two or More Races or Ethnicities — — — — LGBTQ+ — Persons with Disabilities — Did Not Disclose Demographic Background 3 ​ Corporate Code of Conduct and Ethics We have adopted a corporate code of conduct and ethics that applies to all of our employees, officers and directors, including those officers responsible for financial reporting. Our code of business conduct and ethics is available on our website at https://arrivent.com/ . The information on our website is deemed not to be incorporated in this Annual Report or to be a part of this Annual Report. We intend to disclose any amendments to such code, or any waivers of its requirements, on our website or in a Current Report on Form 8-K. Delinquent Section 16(a) Reports Section 16(a) of the Exchange Act requires our directors, officers and beneficial owners of more than 10% of our common stock to file with the SEC initial reports of ownership and reports of changes in the ownership of our common stock and other equity securities. Such persons are required to furnish us copies of all Section 16(a) filings. Based upon a review of the forms filed with the SEC, we believe that our officers, directors and beneficial owners of more than 10% of our common stock complied with all applicable filing requirements during our fiscal year ended December 31, 2023. 150 Table of Contents ​ Item 11.

Narrative Disclosure to Summary Compensation Table Base Salaries Each named executive officer’s base salary is a fixed component of annual compensation for performing specific duties and functions, and has been established by our board of directors taking into account each individual’s role, responsibilities, skills and expertise. Base salaries are reviewed annually, typically in connection with our annual performance review process, approved by our board of directors and adjusted from time to time to realign salaries with market levels after taking into account individual responsibilities, performance and experience. Annual Bonus Our annual cash incentive program is designed to reward the achievement of corporate objectives and individual performance. Our named executive officers are eligible to receive annual cash incentive awards, with the target bonus opportunity determined as a percentage of their base salary. Bonus payments are based upon the assessments of individual and company performance measured against prospectively determined objectives, including pipeline development, financial and strategic goals, as determined by our board of directors. During our fiscal year ended December 31, 2022, the target annual bonuses for Dr. Yao, Dr. Lutzker and Ms. LaChapelle were 50%, 40% and 40% of their base salary, respectively. The annual bonus earned by each named executive officer with respect to our fiscal year ended December 31, 2022 is reported under the “Non-Equity Incentive Plan Compensation” column in the “Summary Compensation Table” above. During our fiscal year ended December 31, 2023, the target annual bonuses for Dr. Yao, Dr. Lutzker and Ms. LaChapelle remained at 50%, 40% and 40% of their base salary, respectively. The annual bonus earned by each named executive officer with respect to our fiscal year ended December 31, 2023 is reported under the “Non-Equity Incentive Plan Compensation” column in the “Summary Compensation Table” above. Equity Compensation Although we do not have a formal policy with respect to the grant of equity incentive awards to our executive officers, we believe that equity grants provide our executives with a strong link to our long-term performance, create an ownership culture and help to align the interests of our executives and our stockholders. In addition, we believe that equity grants promote executive retention because they incentivize our executive officers to remain in our employment during the vesting period. Accordingly, our board of directors periodically reviews the equity incentive compensation of our named executive officers and may grant equity incentive awards to them from time to time. Our named executive officers have been granted certain options to purchase shares of our common stock, as described in more detail in the “Outstanding Equity Awards at December 31, 2023” table below.

Compensation Risk Assessment We believe that although a portion of the compensation provided to our executive officers and other employees is performance-based, our executive compensation program does not encourage excessive or unnecessary risk taking. This is primarily due to the fact that our compensation programs are designed to encourage our executive officers and other employees to remain focused on both short-term and long-term strategic goals. As a result, we do not believe that our compensation programs are reasonably likely to have a material adverse effect on us. Potential Payments upon Termination or Change-In-Control Executive Severance Plan Each of our named executive officers, as well as Winston Kung, MBA, our Chief Financial Officer and Treasurer, is a participant in the Severance Plan. 155 Table of Contents Under the Severance Plan, if we terminate a participant’s employment without “Cause” at any time other than during the “Change in Control Period”, then the participant is eligible to receive the following benefits: Severance is payable in the form of salary continuation.

On June 9, 2021, our board of directors adopted, and our stockholders approved the 2021 Plan. On October 12, 2023, our board of directors adopted the 2024 Equity Incentive Plan (the 2024 Plan, collectively with the 2021 Plan, the Plans). The Plans provide for, among other things, grants of stock options, restricted stock units, restricted stock and other stock-based awards to employees, directors, consultants who provide services to us and our affiliates. We have 3,952,835 shares of our common stock reserved for issuance under the 2024 Plan (plus any shares available for future grants under our 2021 Plan and any shares underlying outstanding stock awards granted under our 2021 Plan that expire or are repurchased, forfeited, cancelled or withheld). Since our 2024 Plan has been approved by our stockholders, we will not make any additional grants under the 2021 Plan. Other Benefits All of our current named executive officers are eligible to participate in our employee benefit plans, including our medical, dental, vision, life and disability insurance plans, in each case on the same basis as all of our other employees. 401(k) Plan We maintain a 401(k) plan for employees. The 401(k) plan is intended to qualify under Section 401(k) of the Internal Revenue Service Code of 1986, as amended, so that contributions to the 401(k) plan by employees or by us, and the investment earnings thereon, are not taxable to the employees until withdrawn from the 401(k) plan, and so that contributions by us, if any, will be deductible by us when made. Under the 401(k) plan, our employees may elect to 158 Table of Contents reduce their current compensation by up to the statutorily prescribed annual limit and to have the amount of such reduction contributed to the 401(k) plan, and we make a matching contribution of 100% of salary deferral contributions up to 4% of pay for each payroll period. Rule 10b5-1 Sales Plans Our directors and executive officers 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 common stock on a periodic basis. Under a Rule 10b5-1 plan, a broker executes trades pursuant to parameters established by the director or officer when entering into the plan, without further direction from the director or officer. The director or officer may amend or terminate the plan in limited circumstances. Our directors and executive officers may also buy or sell additional shares of our common stock outside of a Rule 10b5-1 plan when they are not in possession of material, nonpublic information. ​ Item 12.

Agreements with Stockholders Amended and Restated Investors’ Rights Agreement On December 16, 2022, in connection with the Series B Preferred Stock Financing, we entered into an Amended and Restated Investors’ Rights Agreement (the Investors’ Rights Agreement) with certain holders of more than 5% of our outstanding capital stock, including LAV Fund VI, L.P. (together with its affiliates, LAV Funds), and VSUM VIII Holdings Limited (together with its affiliates, VSUM), as well as OrbiMed Asia Partners IV, L.P. and OrbiMed Private Investments VIII, L.P. (together with its affiliates, OrbiMed) and Sofinnova Venture Partners XI, L.P. (Sofinnova), each of which, besides VSUM and LAV Funds, is affiliated with certain of our directors and officers. Pursuant to the Investors’ Rights Agreement, these stockholders have registration rights with respect to certain issuances of our capital stock. The registration rights include the right to demand that we file a registration statement or request that their shares be covered by a registration statement that we have otherwise filed, subject, in each case, to certain exceptions. Demand Registration Rights Beginning on July‎ ‎24‎, ‎2024, the holders of a majority of registrable securities then outstanding under the Investors’ Rights Agreement may require us to file a registration statement under the Securities Act on a Form S-1 at our expense, subject to certain exceptions, with an anticipated aggregate offering price, net of the offering expenses, of more than $20.0 million, in which case we will be required to effect the registration as soon as practicable, and in any event within 60 days. We are required to effect only two demand registrations pursuant to this provision of the Investors’ Rights Agreement. Any time after we are eligible to use a registration statement on Form S-3, the holders of at least 10% of our registrable securities under the Investors’ Rights Agreement may require us to file a registration statement on Form S-3 at our expense, subject to certain exceptions, with respect to the then outstanding registrable securities of such holders having an anticipated aggregate offering price, net of the offering expenses, of at least $5.0 million, in which case we will be required to effect the registration as soon as practicable, and in any event within 45 days. If we determine that it would be detrimental to us and our stockholders to effect a requested registration, we may postpone each such registration for a period of up to 60 days; provided that we may neither invoke this right more than once in any 12-month period nor effect a registration for our own account or any other stockholder during such 60 day period. The foregoing demand registration rights are subject to a number of additional exceptions and limitations. Piggyback Registration Rights If we propose to file a registration statement under the Securities Act for the purposes of a public offering of our securities, including, but not limited to, registration statements relating to a secondary offering of our securities but 164 Table of Contents excluding (i) a registration statement relating to the sale or grant of securities to employees pursuant to a stock option, stock purchase, equity incentive or similar plan; (ii) with respect to any corporate reorganization or transaction under Rule 145 of the Securities Act; (iii) a registration on any form that does not include substantially the same information as would be required to be included in a registration statement covering the sale of the registrable securities; or (iv) a registration in which the only common stock being registered is common stock issuable upon conversion of debt securities that are also being registered, the holders of registrable securities are entitled to receive notice of such registration and to request that we include their registrable securities for resale in the registration statement. The underwriters of the offering will have the right to limit the number of shares to be included in such registration. The foregoing piggyback registration rights are subject to a number of additional exceptions and limitations. Expenses of Registration We will pay all registration expenses along with reasonable fees and disbursements, not to exceed $50,000 of one counsel for the selling stockholders selected by the holders of a majority of the registrable securities to be registered, other than underwriting discounts and commissions, related to any demand or piggyback registration. Indemnification The Investors’ Rights Agreement contains customary cross-indemnification provisions pursuant to which we are obligated to indemnify the selling stockholders, in the event of misstatements or omissions in the registration statement attributable to us, and they are obligated to indemnify us for misstatements or omissions attributable to them. Expiration of Registration Rights The registration rights will terminate upon the earliest to occur of (i) the closing of certain liquidation events and (ii) such time after closing of our initial public offering in January 2024 as Rule 144 or another similar exemption under the Securities Act is available for the sale of all such holders’ registrable securities without limitation, during a three-month period without registration. Shanghai Allist Agreements On June 30, 2021, we entered into the Allist License Agreement with Allist, a holder of more than 5% of our outstanding capital stock.

Subject to certain limitations, our amended and restated bylaws require us to advance expenses incurred by our directors and officers. We also maintain a general liability insurance policy, which covers certain liabilities of our directors and officers arising out of claims based on acts or omissions in their capacities as directors or officers. Policies and Procedures for Related Party Transactions In connection with our initial public offering, we adopted a written policy that requires all future transactions between us and any director, executive officer, holder of 5% or more of any class of our capital stock or any member of the immediate family of, or entities affiliated with, any of them, or any other related persons, as defined in Item 404 of Regulation S-K, or their affiliates, in which the amount involved is equal to or greater than $120,000, be approved in advance by our audit committee. Any request for such a transaction must first be presented to our audit committee for review, consideration and approval. In approving or rejecting any such proposal, our audit committee will consider the relevant facts and circumstances available and deemed relevant to the audit committee, including, but not limited to, the extent of the related party’s interest in the transaction, and whether the transaction is on terms no less favorable to us than terms we could have generally obtained from an unaffiliated third party under the same or similar circumstances. ​ Item 14.

We have furnished the foregoing disclosure to KPMG. 166 Table of Contents Policy on Audit Committee Pre-Approval of Audit and Permissible Non-Audit Services of Independent Public Accountant Consistent with SEC policies regarding auditor independence, our audit committee has responsibility for appointing, setting compensation and overseeing the work of our independent registered public accounting firm. In recognition of this responsibility, our audit committee has established a policy to pre-approve all audit and permissible non-audit services provided by our independent registered public accounting firm. Prior to engagement of an independent registered public accounting firm for the next year’s audit, management will submit an aggregate of services expected to be rendered during that year for each of four categories of services to our audit committee for approval. (1) Audit Fees include professional services in connection with the audit of our financial statements, reviews of our interim financial statements, as well as work that generally only an independent registered public accounting firm can reasonably be expected to provide, including comfort letters, statutory audits, and attest services and consultation regarding financial accounting and/or reporting standards. (2) There were no Audit-Related Fees during 2023. (3) There were no Tax Fees during 2023. (4) There were no Other Fees during 2023. Prior to engagement, our audit committee pre-approves these services by category of service. The fees are budgeted, and our audit committee requires our independent registered public accounting firm and management to report actual fees versus the budget periodically throughout the year by category of service. During the year, circumstances may arise when it may become necessary to engage our independent registered public accounting firm for additional services not contemplated in the original pre-approval. In those instances, our audit committee requires specific pre-approval before engaging our independent registered public accounting firm. Our audit committee may delegate pre-approval authority to one or more of its members. The member to whom such authority is delegated must report, for informational purposes only, any pre-approval decisions to our audit committee at its next scheduled meeting. ​ ​ ​ PART IV Item 15.
