Repurchases of Equity Securities.

On November 19, 2025, our Board of Directors authorized a share repurchase program under which we may repurchase up to $25 million of our outstanding shares of common stock, from time to time, through open market transactions, privately negotiated transactions or in such other manners approved by the Board of Directors, in accordance with all applicable securities laws and regulations, including Rule 10b-18 of the Exchange Act. We may enter into a pre-arranged stock trading plan in accordance with the guidelines specified under Rule 10b5-1 to effectuate all or a portion of the share repurchase program. The repurchase program does not obligate us to purchase any shares and does not have an expiration date. The timing and method of any repurchases, which will depend on a variety of factors, including market conditions, are subject to our results of operations, financial condition, liquidity and other factors.

As of the close of trading on June 30, 2026, approximately $16.0 million remained available for repurchase by us under the stock repurchase authorization. The number of shares and average price paid per share for shares repurchased in the quarter ending June 30, 2026, are set forth in the table below:
