Context This activity reflects routine compensation events: vesting of performance stock units, tax-withholding via share disposition (common practice), and the receipt of new long-term incentive awards (options and RSUs) with multi-year vesting/exercise schedules. The withholding sale is not an open-market purchase (not a bullish buy signal); the new awards are standard compensation and will only convert to or be exercisable for stock according to the stated schedules.
