Context

• RSUs are a contingent equity award, not an immediate purchase of shares. No shares are issued until vesting conditions are met; tax consequences and actual ownership occur at vesting/delivery.
• Grants like this are common as part of executive compensation and do not by themselves indicate buying or selling sentiment.
