Key Details

- F1: These were performance-based RSUs certified by the Board’s committee for the three‑year period ended Dec 31, 2025 (certified Feb 18, 2026).

Context
- This was an award/vesting event (not an open-market buy or voluntary sale). The largest disposals here are tax withholdings by the company to satisfy tax obligations at vesting, a routine administrative step rather than an intent to liquidate by the insider.
- Performance-based RSUs vesting requires committee certification of goals; the filing shows certification occurred before the vesting date.
