Context
This was not an open-market purchase or discretionary sale; it reflects PSUs awarded in 2023 that vested based on performance and were settled in shares, with a portion withheld to cover taxes (a common practice on vesting). The filing reports the award and the tax-withholding disposition but gives no commentary on future trading intentions.
