Context
RSU vesting and grants are compensation events and do not represent open-market purchases or discretionary sales by the insider. The conversion + immediate disposition pattern is common when shares are withheld to satisfy tax obligations (the filing shows conversion and a matching disposition). The new RSU grant is a forward-looking award that will only become shares if and when it vests next year.
