GMH Gruppe Acquires Two Business Units of Buderus Edelstahl GmbH
Expansion of rolled steel portfolio and enhancement of machining & heat treatment capacities
GMH Gruppe is acquiring two business units of Buderus Edelstahl GmbH in Wetzlar: the hot rolling mill for large, rolled steel dimensions and the machining and heat treatment facilities for highly complex open-die forged parts. These operations will become part of GMH Gruppe, while the remaining business units will stay under the ownership of Mutares SE & Co. KGaA. The purchase price remains confidential. The transaction is subject to various closing conditions, which are expected to be fulfilled in the fourth quarter, thus enabling the legal completion of the acquisition.
With the integration of Buderus Edelstahl, GMH Gruppe continues to pursue its strategic growth agenda: strengthening existing production capabilities, expanding into new market segments, and enhancing service quality for its customers.
“We are very pleased to integrate Buderus Edelstahl into our group, as it ideally complements our portfolio in two key areas,” said Dr. Alexander Becker, CEO of GMH Gruppe. “The machining and heat treatment of highly complex open-die forgings, as well as the hot rolling mill for large dimensions, are a perfect fit with our strategic business areas: Circular Economy, Green Steel and Heavy Forging.”
The integration of Buderus Edelstahl´s business units into GMH Gruppe is planned for the fourth quarter. “We look forward to welcoming our new colleagues in the GMH family soon. The exchange of expertise and the further development of our sites will create exciting opportunities for everyone involved,” added Dr. Anne-Marie Großmann, CDO of GMH Gruppe.
