COMMERCIAL METALS COMPLETES ACQUISITION OF CONCRETE PIPE & PRECAST, LLC

Irving, TX – December 1, 2025 - Commercial Metals Company (NYSE: CMC) (“CMC”) today announced that it has successfully completed the acquisition of Concrete Pipe & Precast, LLC (“CP&P”) from Eagle Corporation and ECPP, LLC for a cash purchase price of $675 million, subject to customary adjustments.

CP&P is a leading supplier of precast concrete and pipe products to the Mid-Atlantic and South Atlantic regions, selling into seven core states from 17 strategically located facilities. The company offers a complete line of standard and highly engineered precast and reinforced concrete pipe solutions to infrastructure, non-residential, and residential construction markets, and is well positioned to benefit from the structural demand tailwinds in its core regions, including data center construction, stormwater management, industrial re-shoring and infrastructure investment. CP&P has established a strong competitive position through scale in local geographies, a track record of superior customer service, and unique design and engineering capabilities.

“I am thrilled to welcome CP&P’s 700 employees to the CMC team,” said Peter Matt, President and Chief Executive Officer. “This acquisition marks an important milestone in our Company’s growth strategy, helping us bring more value to our customers and create more value for our shareholders.”

CMC anticipates closing its acquisition of Foley Products Company (“Foley”) by the end of calendar 2025. Following the completion of both purchases, CMC will operate one of the largest precast concrete platforms in the United States and will be a leader across the Mid-Atlantic and Southeastern regions.
