Context

• Sales by executives can be routine (diversification, tax planning, liquidity) and do not by themselves indicate a change in company outlook. Because this was an open-market sale of existing shares (not an option exercise or gift), it reduced the insider’s holding but does not convey additional contractual or derivative complexity.
