(2) As of August 31, 2025.

(3) Represents grant of 2,000 DSUs vesting ratably on 2/17/2026, 2/16/2027 and 2/15/2028, with the recipient having the option on 1/19/2026 and 1/18/2027 to defer vesting to the next scheduled vesting. The number of shares of Class B common stock that will be issued depends on the Market Price on the applicable vesting date as compared to the Grant Price of the DSUs ($50.90), with no less than 0.5 shares (Market Price less than $25.45) and no more than 4.0 shares (Market Price greater than $101.80), to be issued for each DSU vested. Upon vesting of all of the DSUs, between 1,000 and 8,000 shares of Class B common stock will have been issued. "Market Price" for each vesting date will be the greater of (i) the closing price for the Class B common stock on the trading date immediately prior to such vesting date, and (ii) the average of the closing prices of the Class B common stock for the 20 trading days ending with the trading day immediately prior to such vesting date.
