"Grants to U.S. eligible participants will be settled ... 6 months following the Reporting Person's termination date."

Termination date is the specific calendar day when a contract, agreement, option or other legal arrangement stops being in effect and any remaining rights or obligations expire. For investors it matters because that date sets deadlines for exercising rights, receiving payments, closing positions or avoiding penalties—similar to the day a lease or warranty ends, after which parties no longer have the same protections or claims.
