Context

• This was vesting of performance-based RSUs, not an open-market purchase or discretionary sale. Shares withheld to satisfy tax obligations are routine and do not represent a market sale of additional shares beyond what's needed for taxes.
• The 165% payout indicates above-target performance for the award period, but this is a description of award mechanics, not a market recommendation.
