        <footnote id="F1">On May 7, 2021, May 16, 2022 and May 15, 2023, the Reporting Person was granted awards of performance-vesting restricted stock units (&quot;PSUs&quot;), which vest over a three fiscal year period in the form of common stock, contingent upon the Issuer's attainment of certain performance objectives between one and three fiscal years. On May 15, 2024, the Compensation Committee of the Issuer's Board of Directors determined that the performance objective goals of the PSUs for the period ending March 29, 2024 had been met for the aggregate number of shares shown. Following certification, the certified portion of the awards remain subject to the time-based vesting conditions, and a portion of the awards vested on May 16, 2024, and the remaining amounts are scheduled to vest in part on May 16, 2025 and May 16, 2026, as applicable.</footnote>
        <footnote id="F2">Represents shares withheld to cover taxes due upon the vesting of PSUs and restricted stock units that were previously granted by the Issuer.</footnote>
