Represents a grant of restricted stock units ("RSUs") that will vest one third on the first, second, and third anniversary of July 14, 2026, subject to the Reporting Person's continued service through the vesting date. Each RSU represents a contingent right to receive one share of the Issuer's Class A Common Stock.
