The vesting of the PSUs was subject to satisfying both a performance-based requirement and a service-based requirement.

The service-based requirement was satisfied because the Reporting Person remained continuously employed by Strategy as an "Eligible Participant" (as defined in the PSU Agreement) through the certification date. All PSUs vested in full upon certification.
