Context RSUs are a form of equity compensation that convert to shares if and when they vest; they are not an immediate market purchase or sale and do not by themselves signal buying or selling intent. For a 10% owner who also manages an entity holding shares, footnotes clarify the limited nature of beneficial ownership and standard vesting restrictions.
