Securities Trading Plans of Executive Officers and Directors

Rule 10b5-1 under the Exchange Act provides an affirmative defense that enables pre-arranged transactions in securities in a manner that avoids concerns about initiating transactions at a future date while possibly in possession of material nonpublic information. Our Insider Trading and Unauthorized Disclosures Policy permits our officers and directors to enter into trading plans designed to comply with Rule 10b5-1.

During the quarterly period ended December 31, 2025, Director Nancy E. Cooper adopted a Rule 10b5-1 trading arrangement, dated October 29, 2025, providing for the sale each quarter of 35 percent of net shares of her director compensation paid in common stock. The duration of the trading arrangement is from the selling start date, February 19, 2026, through November 9, 2026, or earlier if all transactions under the trading arrangement are completed prior to that date. The trading arrangement is intended to satisfy the affirmative defense in Rule 10b5-1(c). None of our officers (as defined in Rule 16a-1(f) under the Exchange Act) or any other directors adopted or terminated a Rule 10b5-1 trading plan or adopted or terminated a non-Rule 10b5-1 trading arrangement (as defined in Item 408(c) of Regulation S-K) during the quarterly period.
