Context

• RSU grants are deferred equity awards that do not represent immediately tradable shares until they vest; the 4,544 RSUs granted here vest at a future date (2028) and are routine compensation. The share disposition was a tax withholding event tied to previously vested RSUs, a common administrative transaction rather than a market-driven sale.
