(a)On August 8, 2023, the Company’s Board of Directors authorized a share repurchase program for up to $5 million of the Company’s outstanding common stock.

In the third quarter of 2025, the Company completed its $5 million share repurchase program authorized on August 8, 2023. On September 10, 2025, the Board of Directors authorized a new common stock repurchase program under which the Company may repurchase up to $3 million of its outstanding common stock.

During the six months ended June 30, 2025, no repurchases of shares were made by the Company.

On December 31, 2025, we adopted a Rule 10b-18 and 10b5-1 trading plan (the "10b5-1 Plan") which allows the Company to purchase shares of our common stock under our announced repurchase programs during certain restricted blackout periods. The 10b5-1 Plan allows for the purchase of up to an aggregate of the lower of (i) common stock totaling a combined $2,000,000 purchase price, excluding commissions; or (ii) 350,000 shares of common stock. Shares of common stock purchased pursuant to the 10b5-1 Plan may only be purchased in accordance with trading requirements adopted by the Company and there can be no assurance as to how many shares of common stock, if any, will be purchased pursuant to the 10b5-1 Plan or at what price any such shares of common stock will be purchased.
