Business Overview

-In April 2017, American Axle & Manufacturing (AAM) completed the acquisition process of Metaldyne Performance Group (MPG). As a result, MPG became a wholly owned subsidiary of AAM.

-The Company manufactures highly engineered metal components for powertrain and safety-critical applications in the light, commercial, and industrial vehicle markets.

-The Company is organized into three segments:

  • HHI: Manufactures highly engineered metal-based components used in powertrain and safety-critical applications primarily for the North American light vehicle market.
  • Metaldyne: Manufactures highly engineered metal-based components for powertrain applications in global light vehicle markets.
  • Grede: Manufactures cast, machined and assembled components for light, commercial, and industrial vehicle markets.

-The Company was formed through the merger of three metal-forming manufacturing companies: HHI Holdings; Metaldyne, LLC; and Grede Holdings. The Company's majority owner, American Securities LLC, and its affiliates acquired HHI Holdings in October 2012; Metaldyne, LLC in December 2012; and Grede Holdings in June 2014. The merger of the three companies was completed in August 2014.
