Extension of Share Repurchase Program

On May 6, 2026, our Board authorized an extension of the Company’s previously announced share repurchase program. As a result of such extension, the share repurchase program will terminate on May 31, 2028. The dollar value of the shares of common stock that may yet be repurchased under the share repurchase program is approximately $8.1 million. Repurchases may be made from time to time at management's discretion on the open market or through privately negotiated transactions in compliance with Rule 10b-18 promulgated under the Exchange Act, subject to market conditions, applicable legal requirements and other relevant factors. Repurchases of common stock may also be made under a Rule 10b5-1 plan, which permits common stock to be repurchased when the Company might otherwise be precluded from doing so under insider trading laws. The share repurchase program does not obligate the Company to purchase any particular amount of common stock and may be suspended, modified or discontinued by the Company without prior notice. This disclosure is responsive to Item 8.01 of Form 8-K.
