        <footnote id="F2">This sale was made to cover withholding taxes following the vesting of the previously granted RSUs pursuant to a durable automatic sales instruction letter adopted by Mr. Howton on August 16, 2024 effecting the sell-to-cover election. The sale does not represent a discretionary trade by Mr. Howton.</footnote>
