Context
This was a straight sale of common stock. Sales by insiders are common and can reflect personal liquidity needs or portfolio management rather than a view on company prospects; purchases typically provide a stronger signal of insider confidence. The PSU-related footnote affects reported beneficial ownership totals but does not change that this specific transaction was an open-market sale.
