Context
RSU grants are a form of equity compensation and do not represent an open-market purchase or sale by the insider. The economic value of this award depends on ERII’s future share price and the vesting schedule; they are commonly used to align executives’ incentives with shareholders but do not by themselves indicate buying or selling intent.
