Additional SEC filing notes

Filing notes and footnotes

Explanation of responses 4 footnotes

Footnote F1

In connection with the vesting on August 20, 2026, of Restricted Stock Units ("RSUs") previously granted to the Reporting Person, the Reporting Person's receipt of 1,296 shares of Class A Common Stock was deferred, resulting in the Reporting Person's receipt instead of 1,296 shares of phantom stock pursuant to the Issuer's deferred compensation plan. The Reporting Person is therefore reporting the disposition of 1,296 shares of Class A Common Stock in exchange for an equal number of shares of phantom stock.

Footnote F2

A portion of these securities are Restricted Stock Units ("RSUs"). Each RSU represents a contingent right to receive one share of the Issuer's Class A Common Stock.

Footnote F3

Each share of phantom stock represents a right to receive one share of Class A common stock.

Footnote F4

The phantom stock becomes payable in one lump sum payment upon separation from service.
