Context

• RSUs are awards that convert into actual shares only upon vesting; this grant is an award rather than an open-market purchase or sale and does not necessarily signal near-term buying or selling.
• For retail investors, awards to directors are common as compensation and primarily indicate alignment with shareholder interests, not an immediate change in insider holdings.
