Context

• RSUs are awards that convert to shares only upon vesting; the May 21 entry is a future‑vesting grant (no immediate cash outlay).
• The 593‑share disposition was a tax withholding (shares retained by the issuer to cover taxes), not an open‑market sale — a routine administrative action rather than a directional bet on the stock.
• For retail investors, grants/vests are informative about compensation but do not necessarily reflect the director’s market view.
