The percent of class is calculated based on 115,626,347 shares of Class A Common Stock outstanding as of July 29, 2026 as reported in the Issuer's Form 10-Q filed on July 30, 2026, as increased by certain amounts of Class A Common Stock issuable upon conversion of RSILP Units (together with an equivalent number of shares of Class V Common Stock) or options beneficially owned by certain of the Reporting Persons, as applicable, as detailed in the comments to the cover pages. The previously disclosed percentages in the 13D calculated Class A Common Stock and Class V Common Stock as separate precents. However, this Amendment No. 3 corrects this approach and reports the percent of Class A Common Stock on an as diluted basis.
