        <footnote id="F1">Reflects an award of performance stock units (&quot;PSUs&quot;), originally granted to the Reporting Person on June 21, 2023, that were earned upon the final certification by the Board of Directors of the Issuer (the &quot;Board&quot;) on April 22, 2026, of the level of achievement of the rTSR modifier performance metric for the performance period from April 1, 2023 to March 31, 2026.</footnote>
        <footnote id="F2">The Reporting Person previously reported on a Form 4 filed with the SEC on May 22, 2024 the acquisition of 76,219.5 PSUs as initially earned pursuant to this award based on achievement of the applicable financial metrics for the performance period from April 1, 2023 to March 31, 2024. Such number of PSUs reported on such Form 4 reflected 75% of the number of PSUs initially earned, which was the minimum amount of PSUs that were eligible to be earned and eligible to vest at the end of the three-year performance period, regardless of the level of achievement of the rTSR modifier performance metric (the &quot;Minimum PSU Amount&quot;), subject generally to continued employment through the vesting date.</footnote>
        <footnote id="F3">The number of PSUs reported herein reflects the additional number of PSUs in excess of the Minimum PSU Amount earned upon certification of the Board of the level of achievement of the rTSR modifier performance metric applicable to such award.</footnote>
        <footnote id="F4">Each earned PSU reflects the right to receive one share of the Issuer's common stock upon satisfaction of the applicable vesting conditions.</footnote>
        <footnote id="F5">Reflects the number of shares required to be sold pursuant to a &quot;sell-to-cover&quot; transaction in order to satisfy the tax withholding obligations in connection with the vesting and conversion of PSUs. These sales are mandated by the Issuer's &quot;sell-to-cover&quot; policy adopted by the Issuer on March 2, 2023 pursuant to the requirements of Rule 10b5-1 and its authority under its equity incentive plan, and do not represent discretionary trades by the Reporting Person.</footnote>
