Mr. DeFeo continued, "The acquisition of Powerscreen is an excellent fit with Terex's strategy of extending both the product type and geographic range of our customer offerings.

These products are also sold through distribution channels that complement Terex's existing distribution network. Powerscreen will broaden the strategic position of Terex Earthmoving, Terex Lifting and our emerging light equipment business. We expect to integrate the screening and crushing businesses with Terex Earthmoving, the material handling business with Terex Lifting, and Benford light equipment business with our recent Terex Amida acquisition."
