Context
This is a routine RSU settlement (compensation award converted into shares), not an open‑market purchase or sale. Such settlements are common for directors and do not by themselves indicate a buy/sell market signal. The filing shows the derivative conversion code (M) consistent with RSU settlement; no tax‑withholding or share‑withholding details are provided in the excerpt.
