Context
These transactions are the vesting and settlement of performance-based RSUs. The withholding of shares to cover taxes is a common administrative step (a cashless/stock-withholding settlement) and should not be interpreted as an open-market sale indicating negative sentiment. Awards like these reflect compensation tied to prior performance periods rather than a new purchase by the insider.
