Insights

Corporate Governance Expert

Director reported a large share sale and ongoing RSU holdings.

The Form 4 discloses a disposition of 151,199 shares on 09/30/2025 by director Robert F. Cummings Jr., alongside multiple RSU holdings and a 488-RSU grant. These entries document both cash/stock transactions and deferred equity under the Non-Employee Directors' Deferred Compensation Plan.

This is a factual reporting of insider activity required under Section 16; the filing shows the mechanics of equity compensation (each RSU converts to one share and distribution is deferred per plan rules) without additional context on proceeds, prices beyond the single reported price of $82.03 for the 488-RSU entry, or intent.
