Insights

Corporate Governance Expert

Director sold a large block and still holds significant deferred RSUs.

The Form 4 shows a disposition of 56,888 shares on 09/30/2025, which materially reduces direct share ownership to 107 shares. This is an explicit, reportable sale by a director and is notable for transparency and insider activity tracking.

The filing also documents substantial deferred equity: 51,047 RSUs (annual retainer) plus other RSU balances and a 469-share conversion at $82.03. These RSUs remain subject to deferral rules and convert on participant-elected dates or termination, indicating ongoing alignment via deferred compensation rather than current voting stock.
