        <footnote id="F2">The Reporting Person elected, pursuant to the Issuer's Amended and Restated Deferred Compensation Plan for Directors, to receive deferred stock units in lieu of cash retainer payments for service on the Issuer's board of directors. The price of the deferred stock units reported herein represents the closing price of the Issuer's Class A common stock on January 8, 2026, which price was used to calculate the number of deferred stock units issued to the Reporting Person.</footnote>
        <footnote id="F3">The deferred stock units will be settled for cash or shares of Class A common stock, in the Issuer's discretion, within 45 days of the first to occur of (i) termination of service; (ii) a change in control; (iii) death; or (iv) disability. Deferred stock units issued in lieu of a cash retainer payment are 100% vested on the grant date.</footnote>
