Insights

Financial Analyst

TL;DR: Routine tax-withholding caused a small disposition; overall ownership remains substantial and unchanged in control.

The reported disposition of 6,932 shares at $89.46 is described as shares withheld to cover taxes on vested restricted stock units granted February 25, 2022, indicating this was not an open-market sale to raise cash but an administrative withholding. Post-transaction direct beneficial ownership of 417,745 shares plus 5,691 indirect shares keeps the CEO materially invested in the company. For investors, this is a routine insider administrative action and does not by itself signal a change in strategic ownership or control.

Corporate Governance Expert

TL;DR: The Form 4 documents a standard tax-related withholding on RSU vesting; disclosure is timely and complete.

The filing identifies Christopher A. Cartwright as both a director and President/CEO and discloses the withholding of 6,932 shares to satisfy taxes on vested RSUs. The use of a power of attorney signature on 08/26/2025 is noted. This is a routine Section 16 disclosure consistent with equity compensation administration. There are no additional governance actions or departures reported in this filing.
