Securities Trading Plans of Directors and Executive Officers

Transactions in our securities by our directors and executive officers are required to be made in accordance with our Policy on the Prevention of Insider Trading and Selective Disclosure (the "Insider Trading Policy"), which, among other things, requires that the transactions be in accordance with applicable U.S. federal securities laws that prohibit trading while in possession of material nonpublic information. Rule 10b5-1 under the Exchange Act provides an affirmative defense that enables prearranged 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 Policy permits our directors and executive officers to enter into trading plans designed to comply with Rule 10b5-1.

During the fourth quarter of 2025, none of our directors or executive officers adopted, modified orterminated a Rule 10b5-1 trading plan oradopted, modified orterminated a non-Rule 10b5-1 trading arrangement (as defined in Item 408(c) of Regulation S-K).
