#1 On January 19, 2022, the reporting person received a restricted stock unit award (Award) with price-based vesting conditions. The terms of the Award provide that 1,000 shares vest if the issuer's Class B Common Stock's closing price meets or exceeds $700 for 90 consecutive calendar days on or before December 31, 2027, with an additional 1,000 shares vesting following each additional incremental increase of $100 in the closing price of the issuer's Class B Common Stock maintained for 90 consecutive days on or before December 31, 2027. On November 5, 2024, the first 1,000 shares vested following achievement of the first stock price goal.

#2 Represents the second tranche of the Award, which will vest if the closing price of the issuer's Class B Common Stock exceeds $800 for 90 consecutive calendar days on or before December 31, 2027. As noted above, if such price-based vesting condition is satisfied, the reporting person is eligible for vesting of additional 1,000 share increments of Class B Common Stock for each additional $100 increase in the closing price of the issuer's Class B Common Stock maintained for 90 consecutive days on or before December 31, 2027 (e.g., if the closing price of the issuer's Class B Common Stock exceeds $900 for 90 consecutive calendar days, then 1,000 additional shares of Class B Common stock will vest).
