        <footnote id="F1">The transaction reported represents the withholding of shares by the issuer to satisfy the reporting person's tax withholding obligations in connection with the non-reportable vesting and settlement of restricted stock units.</footnote>
        <footnote id="F2">These shares are represented by restricted stock units (&quot;RSUs&quot;). Each RSU represents a contingent right to receive one share of common stock of the issuer. Of the shares underlying this RSU award, 34% shall vest on June 1, 2027 and the remainder shall vest in equal quarterly installments thereafter on each September 1, December 1, March 1 and June 1, so that all shares of common stock shall be vested as of June 1, 2029, subject to the reporting person's continuous service with the issuer as of each such vesting date.</footnote>
