  1. ELECTION OF DIRECTORS

    ELECTION OF DIRECTORS Our Board is divided into three classes, with one class of our directors standing for election each year. The members of each class are elected to serve a three-year term with the term of office of each class ending in successive years. The Board presently has six members. The Board has nominated, based on the recommendation of the Nominating and Corporate Governance Committee (the “Governance Committee”), two Class II directors to stand for election at the Annual Meeting: Dr. Raymond Sanchez and Gwill York. Both nominees are currently directors of the Company. Dr. Raymond Sanchez was appointed by the Board in August 2025 after being identified and evaluated by members of the Board and management team, and Ms. York was previously elected by our stockholders. If elected at the Annual Meeting, each nominees would serve until the 2029 annual meeting and until the director’s successor has been duly elected and qualified or, if sooner, until the director’s death, resignation or removal. Directors are elected by a plurality of the votes of the holders of shares present at the Annual Meeting or represented by proxy and entitled to vote on the election of directors. Accordingly, the two nominees receiving the highest number of affirmative votes will be elected. Shares represented by executed proxies will be voted, if authority to do so is not withheld, for the election of the two nominees named below. We have no reason to believe that our director nominees will be unavailable for election at the Annual Meeting. In the event that either of our director nominees is unexpectedly not available to serve, proxies may be voted for another person nominated as a substitute by the Board, or the Board may reduce the number of directors to be elected at the Annual Meeting. On March 16, 2026, our Board approved an expansion of the size of the Board of Directors from six to seven directors, in accordance with a Securities Purchase Agreement that we entered into with certain institutional investors, dated March 16, 2026, pursuant to which we issued and sold shares of our common stock and pre-funded warrants to purchase shares of our common stock with an aggregate purchase price of approximately $120 million. All vacancies on the board of directors are filled exclusively by the affirmative vote of a majority of the remaining directors, even if less than a quorum is present, and not by the stockholders. Your proxy cannot be voted for a greater number of persons than the number of director nominees named in this proxy statement. A director elected by the Board to fill a vacancy in a class, including vacancies created by an increase in the number of directors, shall serve for the remainder of the full term of that class and until the director’s successor is duly elected and qualified or such director’s earlier death, resignation or removal. Our corporate governance guidelines encourage our Board, including the nominees for director, to attend our annual meetings. Information relating to the director nominees and each continuing director, including his or her period of service as a director of the Company, principal occupation and other biographical material is shown below.

  20. Outstanding Equity Awards at Fiscal Year End

    All of the equity awards prior to our IPO were granted under the 2019 Plan and all of the equity awards following our IPO were granted under the 2024 Plan. Prior to our IPO, all option awards were granted with a per share exercise price equal to the fair market value of one share of our common stock on the date of grant, as determined by our Board. All option awards granted since our IPO in February 2024 were granted with a per share exercise price equal to the closing sales price of our common stock on the NYSE on the date of grant. (3) Amounts are calculated by multiplying the number of shares shown in the table by $17.80, the closing market price of our common stock on the NYSE as of December 31, 2025. (4) This stock option vests over a period of four years, with 25% of the shares underlying the option vesting on the one year anniversary of the January 1, 2023 vesting commencement date, and 1/48 of the shares underlying the option vesting on a monthly basis thereafter, subject to continued service through each vesting date. (5) In connection with the Repricing described above under “—Narrative to the Summary Compensation Table—Option Repricing,” this stock option was repriced to reduce the exercise price per share to $2.35 (the closing price of our common stock on the New York Stock Exchange on the Repricing Effective Date). There were no changes to the number of shares underlying the stock option or to the vesting schedule of expiration date of the stock option. If the named executive officer exercises the repriced stock option before the end of the Retention Period, the named executive officer would be required to pay a premium exercise price equal to the original exercise price per share shown in the table. The Retention Period had not yet ended for the named executive officer as of December 31, 2025 and accordingly, we have reflected the original exercise price in this table. (6) This stock option vests as follows: 1/3 of the shares underlying the option vested upon completion of the IPO and 2/3 of the shares underlying the option will vest over a period of four years, with 25% of the shares underlying the time-based portion vesting on the one year anniversary of the December 20, 2023 vesting commencement date, and 1/48 of the shares underlying the time-based portion vesting on a monthly basis thereafter, subject to continued service through each vesting date. (7) This stock option vests over a period of four years, with 25% of the shares underlying the option vesting on the one year anniversary of the March 1, 2024 vesting commencement date and 1/48 of the shares underlying the option vesting on a monthly basis thereafter, subject to continued service through each vesting date. (8) The shares underlying the restricted stock unit vest in two equal annual installments on September 1, 2025 and March 1, 2026, subject to the named executive officer’s continuous service as of each such vesting date. (9) This stock option vests over a period of four years, with 25% of the shares underlying the option vesting on the one year anniversary of the February 5, 2025 vesting commencement date and 1/48 of the shares underlying the option vesting on a monthly basis thereafter, subject to continued service through each vesting date. (10) This stock option vests over a period of four years, with 1/48 of the shares underlying the option vesting monthly beginning on the one-month anniversary of the September 21, 2022 vesting commencement date, subject to continued service through each vesting date. (11) This stock option was originally granted at an exercise price of $7.06 per share (the fair market value of our common stock as of the date of grant), which exercise price was amended by our board of directors in April 2023 to reflect an exercise price of $6.23 per share (the then current fair market value of our common stock). Pursuant to the Repricing, the exercise price of the repriced options has been modified to be $2.32 per share (see Footnote 5, above). (12) This stock option vests over a period of four years, with 25% of the shares underlying the option vesting on the one year anniversary of the May 20, 2024 vesting commencement date and 1/48 of the shares underlying the option vesting on a monthly basis thereafter, subject to continued service through each vesting date.

  21. Potential Payments Upon Termination or Change in Control

    Potential Payments Upon Termination or Change in Control Regardless of the manner in which a named executive officer’s service terminates, each of our named executive officers is entitled to receive amounts earned during his term of service, including unpaid salary and unused vacation.
