Context
RSU grants are a common form of equity compensation designed to retain executives; they are not an immediate purchase or sale and do not move shares into the market at grant. Each RSU converts to a share only when it vests and is delivered (and may be subject to withholding or other restrictions at that time). This grant signals a compensation/retention action rather than an immediate insider buy or sell.
