Small-bore piston production: Rheinmetall finalises sale to Comitans Capital AG

  • Sale of small-bore piston production to Comitans Capital AG has now been finalised
  • Transaction effective retrospectively as of 1 April 2024
  • Parting with the pistons business as part of the strategic realignment of the company
  • 3,650 employees at six locations

Rheinmetall has transferred its activities around the small-bore piston production to Comitans Capital AG as planned. Following the announcement of the sale in December 2023, the transaction has now been closed retrospectively as of 1 April 2024 after having received approval from the regulatory authorities.

With this transaction, Rheinmetall has parted with its entire pistons trade, after the large-bore pistons trade had already been sold in January 2023. The disposal of the pistons trade is part of Rheinmetall's strategic realignment, which was launched in 2021 aiming at reducing Rheinmetall's dependence on combustion engine-related products.

With the sale to Comitans, the Rheinmetall Group has achieved its goal of responsibly placing the small-bore pistons division in good hands. Comitans will take over the entire small-bore pistons sector with all production sites and all employees. This includes around 3,650 employees in all six factories in Neckarsulm/Germany, Marinette/USA, Celaya/Mexico, Nova Odessa/Brazil, Trmice/Czech Republic and Hiroshima/Japan as well as two factories of the Chinese joint venture KSHP in Shanghai and Chongqing. Comitans will operate the small-bore pistons division as an independent, autonomous company with its own organisation with the “Kolbenschmidt Pistons” brand. The existing management team of the small-bore pistons division (CEO, CFO and COO) will remain unchanged.
