Insights

Corporate Governance Analyst

TL;DR: Officer reports modest direct holdings plus time‑vested options and RSUs, aligning compensation with tenure.

The reported package combines 5,462 directly owned shares with non‑qualified stock options totaling 8,893 underlying shares and RSUs for 1,815 shares. Exercise prices range from $39.50 to $57.17, and vesting is spread across Q1 2026–Q1 2028 (one RSU vests 04/14/2026), which creates multi‑year retention incentives tied to continued employment.

This is routine for senior officers and is actionable for governance monitoring: watch actual exercises or RSU deliveries as they vest and any future filings that change direct ownership or disclose sales within the next 12–36 months.
