Context
This was primarily an award/vesting event, not an open-market sale: some RSUs converted into shares for the director while a portion was cash-settled (commonly used to cover tax withholding). Derivative-code M denotes conversion/exercise of RSU-like awards. Such cash-settlements are routine and do not necessarily signal insider sentiment about the company’s stock.
