ITEM 9B OTHER INFORMATION

Insider Trading Arrangements

Our directors and executive officers may purchase or sell shares of our common stock in the market from time to time, including pursuant to equity trading plans adopted in accordance with Rule 10b5-1 under the Exchange Act and in compliance with guidelines specified by our insider trading policy. In accordance with Rule 10b5-1 and our insider trading policy, directors, officers and certain employees who, at such time, are not in possession of material non-public information are permitted to enter into written plans that pre-establish amounts, prices and dates (or formula for determining the amounts, prices and dates) of future purchases or sales of our stock, including shares acquired pursuant to our equity incentive plans. Under a Rule 10b5-1 trading plan, a broker executes trades pursuant to parameters established by the director or executive officer when entering into the plan, without further direction from them. The use of these trading plans permits asset diversification as well as personal financial and tax planning. Our directors and executive officers also may buy or sell additional shares outside of a Rule 10b5-1 plan when they are not in possession of material nonpublic information, subject to compliance with SEC rules, the terms of our insider trading policy and certain minimum holding requirements.

During the quarterly period ended June 30, 2025, none of our directors or executive officers adopted orterminated a Rule 10b5-1 trading arrangement or a non-Rule 10b5-1 trading arrangement (each term as defined in Item 408 of Regulation S-K).
