        <footnote id="F1">Each restricted stock unit represents a contingent right to one share of DRCT's Class A Common Stock, par value $0.001 per share, upon settlement.</footnote>
        <footnote id="F2">Due to administrative error, the withholding of shares to satisfy the tax liability incident to the vesting of the restricted stock unit was inadvertently omitted from the original version of this report.</footnote>
        <footnote id="F3">On June 10, 2022, the reporting person was granted 60,900 restricted stock units, vesting in three annual installments beginning on the first anniversary of the grant date. 33% of the restricted stock units vested on June 10, 2023, an additional 33% will vest on June 10, 2024, and the remaining balance of 34% of the restricted stock units will vest on June 10, 2025. Vesting will be accelerated upon certain termination of employment events and upon a &quot;Change in Control&quot; (as defined in the Direct Digital Holdings, Inc. 2022 Omnibus Incentive Plan).</footnote>
