Context

• These were performance-based RSUs that vested after meeting established performance targets over three years — a compensation event rather than an open-market purchase or sale. Tax withholding may reduce the net shares delivered. Such awards are routine executive compensation and do not by themselves signal buy/sell intentions by the insider.
