Insights

Corporate Governance Expert

TL;DR: CEO equity awards and forfeitures were reported, showing standard retention-focused compensation with multi-year vesting.

The Form 4 discloses an RSU award of 23,536 shares and an option grant of 65,161 options at an exercise price of $105.16, with vesting schedules extending from 2026 through 2029 for RSUs and beginning 08/08/2026 for options. Two small forfeitures totaling 1,402.1108 shares were recorded across 08/09/2025 and 08/11/2025.

Compensation Analyst

TL;DR: The grant structure combines time-based RSUs and multi-year option vesting, indicating retention incentive rather than immediate liquidity.

The RSUs vest 25% annually on August 8 from 2026 to 2029, while the stock options vest in three equal annual installments beginning 08/08/2026 and expire on 08/08/2035. The exercise price is explicitly stated as $105.16. Forfeitures noted on 08/09/2025 (816.1095 shares) and 08/11/2025 (586.0013 shares) reduce the CEO's share count to 65,223.7432 shares. From a compensation-design perspective, this is a conventional mix of time-based equity awards.
