19.Stock Incentive Plan

The Company’s stock-based compensation program is designed to attract and retain certain key employees while also aligning employees’ interests with the interests of its stockholders. Stock options have been granted to employees under the stockholder-approved 2014 Stock Incentive Plan (“2014 Plan”) and the stockholder approved 2024 Stock Option and Incentive Plan (the “2024 Plan”). In connection with expiration of the 2014 Plan in July 2024, the available share reserve (including any awards outstanding under the 2014 Plan that lapsed prior to stockholder approval of the new 2024 Plan) was transferred to the 2024 Plan upon stockholder approval thereof. The 2024 Plan provides that the aggregate number of shares of common stock that initially may be issued pursuant to awards granted under the 2024 Plan may not exceed 1,916,011 shares (the “Share Reserve”), along with any awards that transferred over from the 2014 Plan. In addition, the Share Reserve automatically increases on January 1st of each year, for a period of not more than 10 years, beginning on January 1st of the year following the year in which the 2024 Plan became effective and ending on (and including) January 1, 2034, in an amount equal to 4% of the total number of shares of common stock outstanding on

December 31st of the preceding calendar year. The Company’s board of directors may act prior to January 1st of a given year to provide that there will be no January 1st increase in the Share Reserve for such year or that the increase in the Share Reserve for such year will be a lesser number of shares of common stock than would otherwise occur. The available Share Reserve was 1,858,702 shares as of June 30, 2025.

Employee options generally have vesting terms of 1/4th of options being vested one year after the grant date and 1/48th for each month thereafter contingent upon the participant’s continued service beginning on the initial vesting date and ending when the vested ratio equals 1/1. Non-executive members of board of directors have vesting terms of 1/12th and 1/24th of options being vested per month over a period of one and two years.
