        <footnote id="F1">Represents the withholding of shares of common stock of the issuer to pay tax withholding obligations associated with the settlement of certain restricted stock units (&quot;RSUs&quot;) held by the reporting person. These RSUs relate to two RSU awards granted to the reporting person on April 30, 2025, pursuant to the issuer's 2022 Equity Incentive Plan (as amended, the &quot;Plan&quot;), each of which RSU represents a contingent right to receive one share of common stock of the issuer upon vesting and settlement thereof. Of the 7,144 RSUs, in the aggregate, granted on April 30, 2025, to the reporting person, 3,572 vested 12 months from such date, and the remaining 50% will vest in four equal quarterly installments over the 12-month period thereafter, subject to the continuous service of the reporting person on such vesting dates and compliance with the terms and conditions of the Plan.</footnote>
        <footnote id="F2">The reporting person is the managing member of Giri Devanur Holdings LLC and holds sole voting and investment power with respect to those shares of common stock.</footnote>
