Footnotes

F1: The company's stock previously referred to as Class A Common Stock is now referred to as Common Stock following changes made to the company's articles of incorporation. There was no change to any rights related to the stock.

F2: In a Form 4 filed on June 3, 2024 the PSU grant reflected here, due to an administrative error, was reported as Class A Common Stock in Table I rather than a PSU grant in Table II. The PSUs are
hereby being removed from Table I and correctly reported in Table II.

F3: These shares were withheld by the Issuer to cover the tax liability upon the vesting of a time-based restricted stock unit previously granted, and does not represent a discretionary sale by the reporting person.

F4: Includes 1,079 shares acquired pursuant to the Company's 2021 Employee Stock Purchase Plan ("ESPP") for the purchase period of 12/1/2024 to 5/31/2025.

F5: The PSUs are subject to both service-based vesting conditions and a requirement that the average closing price of the Class A Common Stock of Company, as measured over a period of 30 trading
days commencing at the grant date and ending July 1, 2027, equals or exceeds a designated level (the "Stock Price Condition"). The PSUs will vest in one-third installments on each of July 1, 2025, 2026
and 2027, provided that the Stock Price Condition has been satisfied prior to the relevant date. If the Stock Price Condition has not yet been satisfied prior to the relevant date, then the PSUs that
otherwise would have vested on such date will remain unvested unless and until the Stock Price Condition has been satisfied, subject to the Reporting Person's continuous service through the relevant
vesting date.
