In October 2024, the Company adopted the 2024 Equity Incentive Plan (the “2024 Plan”), which became effective in connection with the Company’s IPO. The 2024 Plan provides for the grant of stock options, stock appreciation rights, restricted and unrestricted stock awards, restricted stock unit awards, and other stock-based awards to employees, directors, and non-employee service providers of the Company.

Awards granted under the 2024 Plan expire no later than ten years from the date of grant. The price of stock options shall not be less than 100% of the estimated fair value on the date of grant and typically vest over a four-year period, although awards may be granted with different vesting terms. The 2024 Plan initially reserved 2,143,039 shares of common stock for the issuance of future awards and provides for an automatic annual increase in the number of shares of common stock reserved for future issuance by the lesser of (i) 5% of the number of shares of the Company’s common stock outstanding as of the close of business on the immediately preceding December 31 and (ii) the number of shares determined by the Company’s Board of Directors on or prior to such date for such year. Pursuant to the terms of the 2024 Plan, an additional 604,832 shares of common stock were added to the number of available shares, effective January 1, 2025. As of March 31, 2025, there were 2,579,781 shares of common stock reserved and available for issuance pursuant to the 2024 Plan.

In October 2024, the Company adopted the 2024 Employee Stock Purchase Plan (the “2024 ESPP”), which became effective in connection with the Company’s IPO. The 2024 ESPP initially reserved 214,303 shares of common stock for the issuance of future awards and provides for an automatic annual increase in the number of shares of common stock reserved for future issuance by the lesser of (1) 1% of the number of shares of the Company’s common stock outstanding as of the close of business on the immediately preceding December 31 and (2) the number of shares determined by the Company’s Board of Directors on or prior to such date for such year. Pursuant to the terms of the 2024 ESPP, an additional 201,610 shares of common stock were added to the number of available shares, effective January 1, 2025. As of March 31, 2025, there were 415,913 shares of common stock reserved and available for issuance pursuant to the 2024 ESPP.

The 2024 ESPP permits eligible employees to enroll in six-month offering periods. Participants may purchase shares of the Company’s common stock, through payroll deductions, at a price equal to 85% of the fair market value of the common stock on the first or last day of the applicable offering period, whichever is lower. Purchase dates under the 2024 ESPP occur on or around January 1 and July 1 each year. As of March 31, 2025, there have been no offering periods.

In 2016, the Company adopted the Marauder Therapeutics, Inc. 2016 Stock Option and Grant Plan (the “2016 Plan”) that provided for the grant of stock options, restricted stock units, and other stock-based awards to employees, directors, and non-employee service providers of the Company. The 2016 Plan was suspended in connection with the Company’s IPO and no further grants will be made. The 2016 Plan continues to govern the terms and conditions of outstanding awards granted under the 2016 Plan.
