        <footnote id="F1">On May 12, 2025, the compensation committee of the board of directors of the Issuer determined that the performance criteria had been met, resulting in the vesting of these shares. The performance share units reported on this line were credited due to a performance metric related to the achievement of a pre-established stock price hurdle for the one-year performance period ending May 2, 2025.</footnote>
        <footnote id="F2">Each performance share unit represents a contingent right to receive one share of Common Stock.</footnote>
