Insights

TL;DR: Director purchased a small, clearly disclosed stake increase totaling 3,000 shares at about $13.19 per share.

The filing shows routine insider purchases by a director rather than a coordinated program disclosure; total new shares acquired equal 3,000 and the post-transaction holding is 21,000 shares. Transaction codes are "P", indicating open-market purchases. Given the disclosed sizes and prices, this is informational for ownership monitoring but not clearly material to valuation on its own.

TL;DR: Disclosure is complete and timely; transactions were executed and the Form 4 is properly signed by an attorney-in-fact.

The report identifies the reporting person, relationship as a director, transaction date, and amounts acquired. The signature block shows execution by an attorney-in-fact on 09/16/2025. There are no indications of amendments or other governance issues in the form content provided.
