Eagle Materials Inc.
A maker of cement, concrete and aggregates, gypsum wallboard, and recycled paperboard for infrastructure and residential construction across the U.S. heartland. It began in 1963 as a building-materials arm of homebuilder Centex Corporation, then was spun off in 2004 and renamed Eagle Materials, with the name change pitched as the division "spreading its wings." Its brands include American Gypsum wallboard and Republic Paperboard.
