Arcosa Specialty Materials Revenue and Competitors

Arcosa Specialty Materials is the result of a long and successful history of doing one thing and one thing only. Treating people right. Our customers, our employees, our partners, and vendors. We believe when you take care of the people that matter most, everything else will take care of itself. Our roots go back to 1955 when the Harrison Gypsum Company originally began as a small family operation supplying gypsum to the family farm and neighbors. Originally named the Cement Gypsum Company, Harrison Mine No. 1 was opened near Cement, OK, and underwent the name change to Harrison Gypsum Company in 1956. Over the years the company developed the mining business by supplying raw gypsum rock to nearby manufacturers of Portland cement. As the market area for Harrison Gypsum expanded, gypsum reserves and production capacity also expanded. With business growing, capital investments were made to upgrade to modern mining equipment and improve infrastructure. In 1994, Harrison Gypsum’s mine #2 was named the largest single gypsum mine in the United States by the U.S. Department of the Interior Publication. Today, the total gypsum reserves of Harrison Gypsum Company is estimated to be in excess of a quarter of a billion tons. In 2012, HIG Capital, a leading global private equity investment firm, completed a recapitalization of Harrison Gypsum. This provided Harrison Gypsum with financial and operating resources that will enable us to further capitalize on our significant growth potential. 2015 marked a new chapter in the history of the company when Harrison Gypsum became ACG Materials. This new name gives a strong nod to our history as a company, but also to our future opportunities.
