Context

• RSU grants are a form of equity compensation tied to continued employment and/or performance; the units convert to actual shares only if vesting conditions are met. This grant does not represent an immediate purchase of shares nor an immediate sale; it is compensation that may result in share issuance in 2029 if vesting conditions are satisfied.
