Context

• The disposition was a tax-withholding event (not an open-market sale) commonly used when equity awards vest; it does not necessarily indicate insider sentiment about the stock.
• This was a vesting of long-term performance awards (final payout after the performance period), not an option exercise or discretionary purchase.
