        <footnote id="F2">The Reporting Person was issued RSUs. Each RSU represents a contingent right to receive one share of Common Stock. The RSUs shall vest in three (3) annual installments, with the first tranche vesting on January 24, 2025. The RSUs may be settled only by delivering shares of Common Stock, and thus, the grant is being reported in Table I as allowed per SEC guidance.</footnote>
