Explanation of responses 1 footnote

Footnote F1

The restricted stock units reported in this Form 4 were granted effective June 3, 2026, the date of the Issuer's 2026 annual meeting of stockholders, pursuant to the Issuer's Non-Employee Director Compensation Policy, which provides, among other things, for an automatic annual grant of restricted stock units to eligible non-employee directors. Each restricted stock unit represents the right to receive one share of Class A common stock. The restricted stock units vest on the earlier of the day immediately preceding the date of the Issuer's 2027 annual meeting of stockholders and June 3, 2027, subject to continued service as a director. Settlement of the restricted stock units is deferred pursuant to the reporting person's standing deferral election. Due to administrative oversight, this Form 4 is being filed late.
