• Footnote F1: Company renamed Class A Common Stock to Common Stock in 2025; no change to rights.

Context RSUs are a deferred equity award that convert into shares only if vesting conditions are met; they are not an immediate sale or purchase of stock. Director awards are common as compensation for board service; because this was a grant (not a purchase), it should be interpreted as compensation rather than a direct buy signal.
