        <footnote id="F2">Unless earlier terminated pursuant to, and subject to the terms of, the applicable equity agreement entered into between the reporting person and the Issuer (the &quot;PSU Agreement&quot;), the PSUs shall vest, in ratable tranches representing 25% of the total award, upon the certification of achievement of certain stock price targets for the Issuer's Class A Common Stock, measured with respect to certain performance periods more completely described in the PSU Agreement, with such measurement periods continuing over the four-year period beginning January 15, 2026 and ending January 15, 2030. In the event that any tranche does not vest by the end of the applicable performance measurement period, the PSU comprising such tranche shall be forfeited for no consideration.</footnote>
