Insights

Corporate Governance Expert

TL;DR: CEO reported large option exercises and share sales; transactions include 10b5-1 plan and termination of GRAT indirect holdings.

The filing documents material insider activity by the Chair & CEO: multiple option exercises (235,000 at $39; 372,024 at $35.49) and large open-market sales totaling 994,863 shares across 08/28–08/29/2025 at weighted average sale prices noted as $58.24 and $58.13. The checked 10b5-1 box signals these trades were executed under a pre-established plan. The filing also discloses final GRAT annuity distribution and subsequent termination sales leaving no indirect ownership via the GRAT. For governance review, the key facts are the size of sales by the CEO, the use of a trading plan, and the conversion/monetization of vested option awards.

Securities/Compensation Analyst

TL;DR: Significant option exercises were converted to shares then sold; vesting and exercise dates are disclosed and fully vested.

The Form shows fully vested employee stock options granted 02/13/2019 (235,000 at $39) and 02/12/2020 (372,024 at $35.49) were exercised on 08/28/2025 and the underlying shares were reported acquired and, in multiple transactions, sold the same day or the next. The filing quantifies the exercises and related sales and provides weighted average sale-price ranges. From a compensation perspective, this is routine monetization of vested equity awards but is large in absolute share count and value.
