Suncrete Completes Oklahoma Acquisition

Company Enters Oklahoma City Metro Area with 20 Plants

DALLAS, Oct. 21, 2025 /PRNewswire/ -- Concrete Partners Holding, LLC (d.b.a. Suncrete), a ready-mix concrete logistics and distribution platform strategically located in Oklahoma and Arkansas ("Suncrete" or the "Company"), and Haymaker Acquisition Corp. 4 (NYSE: HYAC), a publicly traded special purpose acquisition company ("Haymaker"), today announced that Suncrete has acquired substantially all of the assets of SRM, Inc. DBA Schwarz Ready Mix and SRM Leasing, LLC and all of the issued and outstanding equity interests of Schwarz Sand, LLC (such assets and equity interests, collectively, "Schwarz"), which companies collectively run a ready-mix concrete business in Oklahoma City, Oklahoma, and surrounding areas.

Randall Edgar, Suncrete's Chief Executive Officer, said, "Today's acquisition significantly expands our operations in the fast-growing Oklahoma City metro area while strategically growing our geographic footprint in the state. With today's transaction, we immediately gain 20 ready-mix plants and more than 100 mixer trucks. We are pleased to welcome more than 200 Schwarz employees to Suncrete. The strong Schwarz reputation represents more than 75 years of service in Oklahoma City, and we greatly value their capabilities and local relationships with a customer-first focus in a dynamic and growing market."

Edgar added, "This acquisition exemplifies our growth strategy to expand Suncrete's geographic reach, scale our business into new local markets and increase our asset base for the production and delivery of high-quality concrete. In addition, we believe this expansion creates new incremental growth opportunities in the surrounding markets. Through our differentiated strategy and company culture, extensive operational experience, technological sophistication, and customer focus, we believe Suncrete can continue to gain scale and grow in the highly fragmented ready-mix industry across the high-growth Sunbelt region of the United States."
