Explanation of Responses:

Id	Content
F1	In connection with the vesting on November 20, 2025, of Restricted Stock Units ("RSUs") previously granted to the Reporting Person, the Reporting Person's receipt of 1,125 shares of Class A Common Stock was deferred, resulting in the Reporting Person's receipt instead of 1,125 shares of phantom stock pursuant to the Issuer's deferred compensation plan. The Reporting Person is therefore reporting the disposition of 1,125 shares of Class A Common Stock in exchange for an equal number of shares of phantom stock.
F2	A portion of these securities are RSUs. Each RSU represents a contingent right to receive one share of the Issuer's Class A Common Stock.
F3	These shares are held of record by the Greg and Christina Baszucki Living Trust dtd 08/18/2006 of which the Reporting Person serves as trustee. The Reporting Person may be deemed to have beneficial ownership of the shares held by the Trust.
F4	These shares are held directly by the Morningstar Dynasty Trust dtd 11/13/2020 of which Bessemer Trust Company of DE, N.A. serves as trustee. The Reporting Person may be deemed to have beneficial ownership of the shares held by the Trust.
F5	These shares are held directly by the Crossbow Dynasty Trust dtd 11/13/2020 of which Bessemer Trust Company of DE, N.A. serves as trustee. The Reporting Person may be deemed to have beneficial ownership of the shares held by the Trust.
F6	These shares are held directly under a Roth IRA account for the Reporting Person (formerly known as the PENSCO Trust Co).
