On December 15, 2025, Mr. Emanuel, our Executive Chair, Chief Executive Officer, and member of the Board of Directors, entered into a Rule 10b5-1 trading arrangement intended to satisfy the affirmative defense of Rule 10b5-1(c) under the Exchange Act, which is a sell-to-cover instruction letter that provides for sales of a number of shares of Class A common stock as is necessary to cover tax withholding obligations incurred in connection with the vesting or settlement of restricted stock units, performance stock units or restricted stock previously granted or that could in the future be granted under the Company’s 2023 Incentive Award Plan (the “Sell-to-Cover 10b5-1 Instruction”). The Sell-to-Cover 10b5-1 Instruction will remain in effect so long as taxes are required to be paid upon the vesting or settlement of restricted stock units, performance stock units or restricted stock awarded or to be awarded to Mr. Emanuel, unless the Sell-to-Cover 10b5-1 Instruction is earlier terminated. The total number of Class A shares that may be sold pursuant to the Sell-to-Cover 10b5-1 Instruction is not determinable. During the three months ended December 31, 2025, no shares of Class A common stock were sold pursuant to the Sell-to-Cover 10b5-1 Instruction.
