F2 · derivative.exercise_price: On November 26, 2024, the reporting person converted, at his election, 516,500 shares of his Class B Common Stock into Class A Common Stock. Each share of Class B Common Stock is convertible at any time at the option of the holder into one share of Class A Common Stock and has no expiration date.

F1 · shares: On November 27, 2024, the reporting person filed a Form 4 (the "Original Filing") which inadvertently reported that on November 26, 2024, he converted, at his election, 500,000 shares of his Class B Common Stock into Class A Common Stock and acquired 500,000 shares of Class A Common Stock. In fact, as reported in this amendment, on November 26, 2024, the reporting person converted, at his election, 516,500 shares of his Class B Common Stock into Class A Common Stock and acquired 516,500 shares of Class A Common Stock.

F1 · derivative.underlying_shares: On November 27, 2024, the reporting person filed a Form 4 (the "Original Filing") which inadvertently reported that on November 26, 2024, he converted, at his election, 500,000 shares of his Class B Common Stock into Class A Common Stock and acquired 500,000 shares of Class A Common Stock. In fact, as reported in this amendment, on November 26, 2024, the reporting person converted, at his election, 516,500 shares of his Class B Common Stock into Class A Common Stock and acquired 516,500 shares of Class A Common Stock.

F3 · balance_after: The Original Filing also inadvertently reported that, following the conversion and acquisition referenced in footnote (1) above, the reporting person directly owned 679,137 shares of Class A Common Stock and 10,490,996 shares of Class B Common Stock. In fact, as reported in this amendment, following such conversion and acquisition, the reporting person directly owned 695,637 shares of Class A Common Stock and 10,474,496 shares of Class B Common Stock. As a result of the foregoing inadvertent errors, the ending balance of shares of Class A Common Stock in the Original Filing and all subsequently filed Forms 4 underreported 16,500 shares of Class A Common Stock directly owned by the reporting person. This amendment also serves to correct the ending balance of Class A Common Stock directly owned by the reporting person as of November 27, 2024, and in all Forms 4 filed thereafter but prior to the filing of this amendment. All subsequent Form 4 filings will reflect this correction.
