Business Overview

-A major supplier to Nissan, Calsonic Kansei acquired a major Italian lamp manufacturer, Magneti Marelli, in 2019 and renamed the company to Marelli.

-The main products of the former Calsonic Kansei are cockpit modules/interiors, air conditioning systems, heat exchangers, and compressors. The main products of the former Magneti Marelli (Now is Marelli Europe S.p.A.) are lighting, electronics, and powertrain.

-The Company operates through 10 business areas: Automotive lighting and sensing, Electric powertrain, Thermal solutions, Electronics systems, Green technology solutions, Interior experience, Powertrain, Ride dynamics, Motorsport, and Aftermarket.

-On May 2023, the Company announced the creation of Marelli Propulsion Solutions division. The new division combines Powertrain and Electric powertrain businesses and plan to support the customers’ electrification journey with co-created innovation. It focuses on software enabled components and systems such as battery management systems and smart actuators, as well as on vehicle software architecture like vehicle domain controls.


Business revitalization plan

-In March 2022, the company filed an application for a Turnaround ADR, a type of private liquidation, because its total liabilities exceeded 1 trillion yen. The company said it would request debt forgiveness from Mizuho Bank, its main bank, and other financial institutions with which it does business. In June of the same year, the company was unable to obtain the consent of all creditors at a meeting of creditors and decided to move into civil rehabilitation proceedings.

-In July 2022, the Company started its simplified civil rehabilitation. With the simplified civil rehabilitation proceeding, the Company can take over the rehabilitation plan of the ADR proceeding. At the same month, the Company’s business revitalization plan including additional investment by KKR & Co. Inc., a U.S. investment fund, and debt waiver by financial institutions has also been approved. The business revitalization plan will focus on the reassessment of the organization and workforce system, cost competitiveness reinforcement, and investment in human resources and innovation.

-In August 2022, the Company announced that the approval of its business revitalization plan by the Tokyo District Court had been confirmed. Revitalization proceedings were concluded with the confirmation of approval. Moreover, the revitalization plan will come into effect, and the parent company's US investment fund KKR will make an additional investment in Marelli, and financial institutions will waive their claims.
