Context
This was a performance‑based equity vesting event (award of PSUs), not an open‑market purchase or a deliberate sale for liquidity. The 7,286‑share disposal was a tax‑withholding/cashless settlement to cover withholding obligations arising from the PSU vesting, a routine administrative step common with equity awards.
