Item 8.01 Other Events.

On May 11, 2026, the Company's Board of Directors authorized the Company to repurchase up to an aggregate of $10.0 million of its common stock (“May 2026 Share Repurchase Program”).

The May 2026 Share Purchase Program may be effected, from time-to-time, through open market purchases, privately negotiated transactions, Rule 10b5-1 plans, accelerated stock repurchases, block trades, derivative contracts or otherwise in compliance with Rule 10b-18 of the Securities Exchange Act of 1934, as amended. The May 2026 Share Repurchase Program is not subject to a termination or expiration date, and it does not obligate the Company to acquire any specific number of shares.
