Context

• RSUs are contingent awards that convert to actual shares only upon vesting; they do not represent immediate transferable ownership. Performance-based RSUs depend on future stock-price performance metrics, while time-based RSUs vest over four years. These grants are typical executive compensation and should be viewed as incentive alignment rather than an immediate market buy or sell.
