Insights

Securities Analyst

TL;DR: Insider executive bought 2,500 shares at $14.945, modestly increasing direct ownership to 17,500 shares.

The transaction is a routine Section 16 filing documenting a small open-market purchase by an executive who is also a director. The purchase size (2,500 shares) and post-transaction direct holding (17,500 shares) are modest relative to typical institutional positions and likely do not materially change insider alignment with shareholders. The unit price of $14.945 is disclosed; no derivative activity or additional cash consideration beyond the per-share price is reported. The filing includes a power-of-attorney signature dated 08/26/2025.

Corporate Governance Expert

TL;DR: Disclosure is complete for the reported non-derivative purchase and shows direct and indirect holdings.
