As previously announced, on June 26, 2025, MRC Global Inc., a Delaware corporation (“MRC Global” or the “Company”), entered into an Agreement and Plan of Merger (the “Merger Agreement”) with DNOW Inc., a Delaware corporation (“DNOW”), Buck Merger Sub, Inc., a Delaware corporation and a wholly-owned, direct subsidiary of DNOW (“Merger Sub”), and Stag Merger Sub, LLC, a Delaware limited liability company and a wholly-owned, direct subsidiary of DNOW (“LLC Sub”). The Merger Agreement provides that, among other things and subject to the terms and conditions of the Merger Agreement, (1) Merger Sub will be merged with and into MRC Global (the “First Merger”), with MRC Global continuing as the surviving corporation in the First Merger (the time the First Merger becomes effective, the “Effective Time”) and (2) immediately following the First Merger, MRC Global will be merged with and into LLC Sub (the “Second Merger” and, together with the First Merger, the “Mergers”), with LLC Sub continuing as the surviving company at the effective time of the Second Merger as a wholly-owned, direct subsidiary of DNOW. The Mergers and the other transactions contemplated by the Merger Agreement are herein referred to as the “Transactions.”

The Transactions are conditioned on, among other things, the expiration or early termination of the statutory waiting period under the Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended (the “HSR Act”), and other required regulatory approvals. The statutory waiting period under the HSR Act expired on October 6, 2025. The Transactions remain subject to the remaining customary closing conditions and approvals and the receipt of other required regulatory approvals.
