Context
These were open‑market sales (dispositions). Sales by executives can be routine (e.g., for diversification or liquidity) and do not by themselves indicate the company’s outlook; purchases tend to be more directly interpreted as bullish. The filing includes weighted‑average price ranges (see F1, F2), and no additional details (e.g., 10b5‑1 plan or tax withholding) were provided in the summary.
