Eagle Materials to expand, modernize Oklahoma gypsum wallboard plant

Eagle Materials (EXP) announced that its subsidiary company, American Gypsum, plans to expand and modernize its Duke, Oklahoma gypsum wallboard plant, which serves customers throughout the South and Sunbelt and is strategically located near decades of low-cost natural gypsum reserves. The project will expand American Gypsum’s ability to serve customers in high-growth markets and enhance its low-cost producer position in the wallboard industry. Upon completion, the project will increase the plant’s annual wallboard manufacturing capacity by 300M square feet, or 25%, to approximately 1.5B square feet, and will enable, with moderate additional investment in the future, a further 500 million square feet of capacity expansion, for a total of 2B square feet of manufacturing capacity. The facility will be upgraded with technology that will increase operating efficiencies, simplify maintenance programs, and reduce natural gas usage, resulting in manufacturing cost savings of almost 20%. The total project investment is estimated to be $330M. Planning for the project has been completed, all regulatory approvals have been received, and construction is expected to begin immediately, with startup scheduled for the second half of calendar year 2027.
