Context
RSU grants are a form of equity compensation and do not represent an immediate market purchase or sale; they become valuable only if and when they vest and convert to shares. This filing reports a grant (compensation) rather than a buy or sale; it’s factual disclosure of executive compensation, not a direct market signal.
