Certain of the RSUs remain subject to service-based vesting conditions.</footnote>
        <footnote id="F3">Represents the number of shares withheld by the Issuer in connection with the net settlement of the applicable RSUs prior to the open of trading on September 19, 2023, which settlement date was determined by the Issuer's board of directors, to satisfy the tax obligation realized upon vesting of such RSUs.</footnote>
