Context

RSU grants are a common form of executive compensation to align management with shareholder interests; they do not represent immediate ownership until vested and settled.
Because the award vests over multiple dates through 2029 and may be settled in cash or stock, it should be viewed as long-term compensation rather than an immediate market signal.
