( 2 )Consists of securities held by the Daniel S. Kotcher Revocable Trust u/t/a dated December 7, 2012 (the "Kotcher Trust"). The reporting person is a beneficiary of the Kotcher Trust and may be deemed to have a beneficial ownership interest with respect to the securities held thereby, and the reporting person's husband, Daniel Kotcher, serves as trustee of the Kotcher Trust and exercises sole voting and investment control over such securities. The reporting person disclaims beneficial ownership of the securities held by the Kotcher Trust except to the extent of her actual pecuniary interest therein. ( 3 )The shares of Class V Voting Stock of the Issuer provide no economic rights in the Issuer to the holder thereof. However, each holder of Class V Voting Stock will be entitled to vote as a common stockholder of the Issuer, with the number of votes equal to the number of shares of Class V Voting Stock held at the time of such vote. ( 4 )Shares were sold pursuant to a 10b5-1 Plan dated September 26, 2024. ( 5 )The reported price in Column 4 is a weighted average sale price. These shares were sold in multiple transactions at prices ranging from $13.27 to $13.775 per share. The Reporting Person undertakes to provide to the Issuer, any security holder of the Issuer, or the staff of the Securities and Exchange Commission, upon request, full information regarding the number of shares sold at each separate price within the range set forth in this footnote. ( 6 )Pursuant to the Amended and Restated Limited Partnership Agreement of RSI LP, beginning on June 29, 2021, the RSI Units beneficially owned by the reporting person's spouse may be exchanged, at any time, at the election of the holder, and has no expiration date, subject to certain conditions, for one share of Class A Common Stock of the Issuer. Upon such exchange, an equivalent number of shares of Class V Voting Stock then held by the reporting person's spouse will be canceled.
