10b5-1 Trading Arrangements

On June 10, 2026, Jonathan Steinberg, our Chief Executive Officer, entered into a written trading plan intended to satisfy the affirmative defense conditions of Rule 10b5-1(c) under the Exchange Act. Subject to the terms of the plan, Mr. Steinberg may sell up to approximately 635,000 shares of our common stock, representing shares deliverable upon vesting of restricted stock awards and performance-based restricted stock units, in each case net of shares withheld to satisfy tax withholding obligations. The plan will terminate on June 10, 2027, or upon the earlier completion of all transactions under the plan. The plan wasadopted during an open trading window, and no sales will commence under the plan until completion of the applicable cooling-off period required by Rule 10b5-1(c).

During the three months ended June 30, 2026, none of our other directors or officers (as defined in Rule 16a-1(f) of the Exchange Act) adopted, modified or terminated a Rule 10b5-1 trading arrangement or non-Rule 10b5-1 trading arrangement (as such terms are defined in Item 408 of Regulation S-K).
