Bolton Plant

Tokyo, July 16, 2025- Astemo UK Ltd., (hereafter “Astemo UK”) a wholly owned subsidiary of Astemo Ltd. (hereafter “Astemo”) that is responsible for Astemo's UK operations, will build a new production line for inverters for next-generation EVs^* at its Bolton plant, which is based in Greater Manchester in Northern England. This initiative, which aims to strengthen Astemo UK’s electrification business, has been approved by the UK Government’s Automotive Transformation Fund (hereafter “ATF”) in the UK, and production is scheduled to begin in April 2027. Through the support of the ATF, Astemo and Astemo UK will build a supply chain for electrification products in the European region.

The ATF is led by the Department for Business and Trade in partnership with the Advanced Propulsion Centre. Under the Government’s new DRIVE35 program, the ATF will continue to unlock private investment in strategic zero-emission vehicle technologies in the UK.

Expected to create and secure employment for an estimated 220 jobs, this investment by Astemo and Astemo UK for the new inverter production line aims to ensure a stable supply of electrification products for the UK and EU markets. The total program investment will be over 100 million pounds.

Designed with electromagnetic compatibility (EMC) in mind and compliant with the strict European market standards, the next-generation inverters will be highly efficient, compact, and lightweight. In addition, through establishing local production systems the product will comply with the green procurement policies of major automobile manufacturers, which can contribute to the reduction of Scope 3 emissions throughout the supply chain by avoiding the transporting of products from other regions. This will enable Astemo UK to further capture market share, by supplying products that meet the needs of the European region.

Through this investment, Astemo and Astemo UK will contribute to the decarbonization of the UK and Europe and realizing a sustainable mobility society, while accelerating the strengthened global supply of electrification products.

"We are honored by the UK Government's support, which reflects the high regard it has for our electrification technology,” said Astemo Senior Executive Vice President Toru Kamioke. "This investment in our Bolton plant in the UK will mark the fourth country in which Astemo manufactures electrification products, following Japan, the US and China. It is an important achievement in our global electrification supply chain. Through the supply of products from the Bolton plant, we will respond to Europe’s EV market growth, while contributing to job creation and the development of the UK automotive industry."
