        <footnote id="F1">The reported securities are represented by restricted stock units (&quot;RSUs&quot;), of which one-third will vest on April 6, 2027 and the remaining two-thirds will vest in equal quarterly installments thereafter on the last day of each of the subsequent eight quarters, rounded down to the nearest whole share until the last such installment, such that one-hundred percent of the RSUs will be vested on the third anniversary of April 6, 2027, subject to the Reporting Person's continuous employment on each applicable vesting date.</footnote>
        <footnote id="F2">The reported securities were subject to a performance restricted stock unit (&quot;PRSU&quot;) award that was initially granted on February 1, 2025, and were earned by the Reporting Person upon the achievement of certain performance criteria as certified by the Compensation and Human Capital Committee of the Issuer's Board of Directors on February 2, 2026.</footnote>
        <footnote id="F3">These shares were withheld by the Issuer in order to satisfy certain tax withholding obligations in connection with the issuance of shares upon the vesting of PRSUs.</footnote>
