Insights

Corporate Governance Analyst

Director sold a small stake across multiple accounts; holdings remain diversified across trusts and plans.

The report documents a total of 1,100 shares sold on 10/08/2025 at weighted average prices around $65.66. The sales are recorded as direct and indirect dispositions and the filing identifies multiple remaining holdings by the reporting person through a profit sharing plan, trusts, spouse and a limited partnership.

The main dependency is that the Form 4 only discloses transactions and post-sale holdings; it does not state intent or reason for the sales. Investors may monitor subsequent Section 16 filings for additional changes over the next few reporting periods.
