CLAYTON, Missouri — Olin Corp. announced Tuesday it is set to buy ammunition manufacturing equipment from an Arizona company for $75 million. The deal is expected to close in the second quarter of 2025.

The acquisition between Clayton-based Olin and AMMO, Inc. includes AMMO’s brass shell capabilities and a 185,000-square-foot production facility the company owns in Manitowoc, Wisconsin, less than 50 miles southeast of Green Bay.

The small-caliber manufacturing assets will become part of Olin’s Winchester Ammunition business. The Wisconsin plant will “enable greater specialization and broader participation across high-margin specialty calibers,” Olin said in a press release.

"The Manitowoc assets will extend Winchester's leadership position and expand the reach and value of our near full integration," Brett Flaugher, Olin’s president of Winchester Ammunition, said in a statement. "The acquired assets will enable our legacy plants to lower costs of existing high-volume products and increase our ability to participate in higher-margin specialty rounds at a cost advantage."

The AMMO deal follows Olin's recent acquisition of sport-shooting company White Flyer Targets, which closed in October 2023.

Olin’s chemical businesses produce products such as chlorine and caustic soda, vinyls, epoxies and chlorinated organics. The company’s ammunition segment, Winchester, produces and distributes sporting ammunition, law enforcement ammunition, reloading components, small-caliber military ammunition and components and industrial cartridges.
