Rule 10b5-1 trading arrangement

During the three months ended August 31, 2025, one of our directors or executive officers adopted, modified orterminated a Rule 10b5-1 trading arrangement or a non-Rule 10b5-1 trading arrangement as defined in Item 408 of Regulation S-K.

On August 14, 2025, the Company’s Chief Legal Officer and Secretary, Tara D. Mackey, entered into a Rule 10b5-1 trading arrangement providing for the potential sale of an aggregate of up to 8,281 shares of the Company’s common stock acquired upon the vesting of restricted stock units and performance stock units previously awarded to Ms. Mackey under the terms of the Company’s 2014 Long-Term Incentive Plan. The trading arrangement is intended to satisfy the affirmative defense in Rule 10b5-1(c) under the Securities Exchange Act of 1934, as amended. The first date that sales of any shares are permitted to be sold under the trading arrangement is November 13, 2025, and subsequent sales under the trading arrangement may occur from time to time for the term of the trading arrangement which expires on August 15, 2027, or earlier if all transactions under the trading arrangement are completed prior to such date.
