        <footnote id="F1">On February 21, 2023, Ribeye Parent, LLC (&quot;Parent&quot;) acquired the Issuer pursuant to the Agreement and Plan of Merger by and among the Issuer, Parent and Ribeye Merger Sub, Inc., a direct, wholly owned subsidiary of Parent (&quot;Merger Sub&quot;), dated as of December 11, 2022 (the &quot;Merger Agreement&quot;). In accordance with the Merger Agreement, Merger Sub merged with and into the Issuer, with the Issuer surviving such merger as a wholly owned subsidiary of Parent (the &quot;Merger&quot;). Prior to the Merger, LLC Units of Weber Holdco LLC were exchangeable at the holder's direction on a one-for-one basis for an equal number of shares of Class A Common Stock of the Issuer, at which time an equal number of shares of Class B Common Stock of the Issuer would be cancelled.</footnote>
        <footnote id="F2">(Continued from footnote 1) In connection with the Merger, each share of Class B Common Stock outstanding prior to the effective time of the Merger (other than certain shares of Class B Common Stock canceled for no consideration pursuant to the Merger Agreement) was converted into an identical number of newly issued shares of Class B common stock of the surviving corporation.  As a result of the Merger, the LLC Units are no longer redeemable for Issuer's Class A Common Stock and became redeemable instead for Class A common stock of the surviving corporation.</footnote>
