Context
The award appears to be vesting of equity (RSUs) rather than a market purchase. The subsequent sale was used to cover withholding and fees per a pre-established 10b5-1 instruction, which is a routine, non-discretionary transaction and is commonly treated differently by investors than an elective sale.
