Context

• RSUs are a form of equity compensation that convert to actual shares only when they vest; they do not represent immediately tradable shares. Grants to directors are common and typically reflect compensation or retention, not a direct purchase or sale signal. This Form 4 was filed within the required two business days, so there is no late-filing issue.
