TL;DR: A routine insider buy of 5,000 shares increases director ownership modestly; no other material changes.

John McCartney, identified as a director, purchased 5,000 common shares at $5.30, raising his reported holdings to 77,117 shares. The transaction is a straightforward open-market purchase reflected on a Form 4 with no associated derivatives or dispositions noted. For investors, this is a limited-significance insider purchase absent size context relative to outstanding shares or unusual timing.

Corporate Governance Expert

TL;DR: Director reported a small-scale purchase; filing procedures appear correct and timely.

The Form 4 indicates proper disclosure of a director’s acquisition with signature by a power of attorney. The report shows the reporting person checked the director box and filed as one reporting person. There are no indications of Rule 10b5-1 plan usage, amendments, or complex ownership structures. Governance compliance appears routine.
