Insights

Financial Analyst

TL;DR: A director purchased 618 shares at $25.25, a routine insider buy with limited size relative to total holdings.

The reported acquisition of 618 shares at $25.25 is a clear, direct purchase and increases the director's direct stake to 67,904 shares. There are no derivative instruments reported, which simplifies assessment of economic exposure. The transaction size appears modest versus the reported total holdings, so while it is a positive disclosure of insider buying, it is unlikely on its own to be material to valuation or signal a major change in insider sentiment.

Corporate Governance Expert

TL;DR: Filing documents a standard Section 16 disclosure of an insider purchase, properly executed by a POA.

The Form 4 identifies the reporting person as a director and records a purchase on 09/30/2025. The signature by a power of attorney (Terri J. Ziepfel) dated 10/01/2025 is consistent with procedural requirements. No amendments or additional transactions are shown. From a governance and compliance perspective, the filing appears complete for the reported transaction.
