Context

The sale was disclosed as a tax-withholding sale tied to the vesting of restricted awards (routine administrative transaction), rather than a standalone discretionary sell for investment reasons.
The awards are time-vesting (RSUs and option-like vesting) and do not represent an immediate purchase of free-and-clear shares until they vest; the derivative award vests monthly over four years.
