TopBuild Corp. entered into a Third Supplemental Indenture for its 4.125% Senior Notes due 2032 and a First Supplemental Indenture for its 5.625% Senior Notes due 2034. The amendments were approved by a majority of noteholders in connection with the previously announced acquisition by QXO, Inc. Key changes include the elimination of restrictive covenants, asset sale limitations, and change of control repurchase requirements. The amendments become operative only upon the successful consummation of the tender offer and the satisfaction of the merger condition. Events of default have been significantly reduced, now primarily limited to failure to pay principal and interest.
