Rule 10b5-1 Trading Plans Adopted by Officers and Directors During the Fourth Quarter

During the three months ended June 30, 2024, the following officers of the Company adopted trading plans to sell and/or gift shares of our common stock that have been or will be issued upon the vesting of RSUs, or purchased in our Employee Stock Purchase Plan, that are intended to satisfy the affirmative defense conditions set forth in Rule 10b5-1(c) under the Securities Exchange Act. The material terms of the trading plans other than pricing conditions are set forth in the table below:

• Due to pricing conditions in the trading plans, the number of shares actually sold under the trading plans may be less than the maximum number of shares that can be sold. Shares sold under plans upon the vesting of PRSUs where the performance conditions have not been met at the time of plan adoption or are to be purchased in the future under our employee stock purchase plan are calculated at the maximum number of shares that may be issued, with fractional shares disregarded.

^ For RSUs that have not vested, the maximum number of shares to be sold does not take into account shares withheld for taxes.

** Mr. Higgins’ trading plan terminates when the last trade is placed under the plan. The last scheduled trade is on May 22, 2025; provided that if any scheduled trades are not placed because of trading conditions set forth in the plan, the trading plan will terminate on June 30, 2025.
