The reporting person received an award of 8,681 restricted stock units on May 29, 2026, which vest quarterly in four equal installments over one year, with the first such vesting event occurring on August 29, 2026. Each restricted stock unit represents the right to receive one share of Class A Common Stock upon vesting. Pursuant to the issuer's Deferred Compensation Plan for Non-Employee Directors, the reporting person elected to defer receipt of the underlying shares of Class A Common Stock upon vesting of the restricted stock units and will instead receive an equal number of shares of phantom stock. Each share of phantom stock represents the right to receive one share of Class A Common Stock upon the reporting person's separation from service with the issuer.
