Footnote F1

In connection with the vesting on August 20, 2026, of Restricted Stock Units ("RSUs") previously granted to the Reporting Person, the Reporting Person's receipt of 1,296 shares of Class A Common Stock was deferred, resulting in the Reporting Person's receipt instead of 1,296 shares of phantom stock pursuant to the Issuer's deferred compensation plan.
