Insights

Corporate Governance Expert

TL;DR: A company director made a routine open-market purchase of 268 shares, modestly increasing direct ownership.

The reported acquisition by Director Jeffrey J. Barnes is a straightforward disclosure of insider buying. At 268 shares for $33.13 each, the purchase size is small relative to total reported holdings of 41,221.7188 shares. The filing explicitly states some holdings arise from dividend reinvestment, and the Form 4 was executed by power of attorney. This appears to be a routine, compliant Section 16 disclosure with no additional governance actions or changes reported.

Securities Analyst

TL;DR: Insider purchase reported; transaction size is minor and is unlikely to be materially market-moving.

The Form 4 documents a purchase on 09/02/2025 of 268 common shares at $33.13, increasing the director's direct beneficial ownership to 41,221.7188 shares. The note that dividend reinvestment contributed to total holdings explains the fractional share amount. No options, derivatives, sales, or other compensatory transactions are reported. This is a routine disclosure for investor transparency under Section 16.
