Rule 10b5-1 Trading Plans

The Company’s directors and officers (as defined in Rule 16a-1(f) under the Exchange Act) are only permitted to trade in the Company’s securities pursuant to a prearranged trading plan intended to satisfy the affirmative defense of Rule 10b5-1(c) under the Exchange Act (a “Rule 10b5-1 Plan”). During the three months ended December 31, 2025, one of the Company’s officers adopted a Rule 10b5-1 Plan, which was entered into during an open trading window in accordance with the Company’s Insider Trading Policy and Trading Plan Policy.

On December 3, 2025, Lawrence Brock, the Company’s Chief People Officer, entered into a Rule 10b5-1 Plan (the “Brock Plan”) providing for the potential sale of up to 86,393 shares of Class A common stock owned by Mr. Brock, plus an additional undetermined number of shares of Class A common stock to be received by Mr. Brock upon the future grant, vesting, and settlement of RSUs for shares of Class A common stock, including upon the vesting and settlement of RSUs for shares of Class A common stock and the exercise of vested stock options for shares of Class A common stock, so long as the market price of the Class A common stock is higher than certain minimum threshold prices specified in the Brock Plan or, in certain circumstances, at the market price, between an estimated start date of March 4, 2026 and May 28, 2027. The Brock Plan provides for the sale of shares of Class A common stock to be received by Mr. Brock upon the future grant, vesting, and settlement of RSUs for shares of Class A common stock.

The Brock Plan also provides for the sale of shares of Class A common stock to be received upon the future vesting and settlement of certain outstanding RSUs, net of any shares withheld or mandatorily sold by the Company to satisfy applicable tax obligations and shares sold pursuant to Mr. Brock’s prior Rule 10b5-1 Plan dated December 2, 2024 (the “Prior Brock Plan”). The numbers of shares (i) to be received by Mr. Brock upon the future grant, vesting, and settlement of RSUs for shares of Class A common stock and (ii) to be withheld or mandatorily sold by the Company or sold pursuant to the Prior Brock Plan, and therefore the exact number of shares to be sold pursuant to the Brock Plan, can only be determined upon the occurrence of the future vesting events. For purposes of this disclosure, we have included the maximum aggregate number of shares to be sold without (i) including any shares to be sold upon the future vesting and settlement of any RSUs that have not yet been granted and (ii) subtracting any shares to be withheld or mandatorily sold by the Company upon future vesting events or to be sold pursuant to the prior Brock Plan.
