Marelli Holdings

On August 25, 1938, Calsonic Corp. was founded as Nihon Radiator Manufacturing Company, Ltd., with radiators as its product line. Nagao Gentaro was its first president. By 1988, Nihon Radiator changed its name to Calsonic Corporation in celebration of its 50th anniversary. KKR stated that its intention in buying Calsonic Kansei would be to help its international expansion while the company's local Japanese market is shrinking. On October 22, 2018, Calsonic Kansei announced that it would be merged with components manufacturer Magneti Marelli from Fiat Chrysler Automobiles (FCA), acquired by the parent fund KKR for $7.1 billion (€6.2 billion). The news was mostly wrongly reported by the press as Calsonic Kansei purchasing Magneti Marelli, while the transaction happened between KKR and FCA. The company's previous bid of nearly $5.9 billion was deemed too low by FCA. By May 2019, Calsonic Kansei and Magneti Marelli united under one brand name, Marelli, as part of its strategy to compete on a global scale. On June 7, 2025, Marelli Holdings warned that it may file for Chapter 11 bankruptcy protection in the US. On June 11, 2025, Marelli Holdings filed for Chapter 11 bankruptcy protection with plans to eliminate debt and sell itself to new owners. ==Business segments and products==
