Context

• This is a sale by a 10% owner (large shareholder), which can reflect portfolio rebalancing or other personal reasons; sales by large holders are common and do not by themselves indicate company performance.
• No options exercise, award, gift, or tax-withholding detail is included—this was a straight open-market sale.
