Transfer of new development projects for automotive power supply products from TDK

Tokyo, September 25, 2025 – Astemo Ltd. (hereafter “Astemo”) will enter into a definitive agreement to succeed the new development business for automotive power supply products operated by TDK Corporation (hereafter “TDK”) through a corporate spin-off (absorption-type split, hereafter “this Matter”). Based on this agreement resolved at Astemo’s board meeting on September 25, 2025, both companies will execute the absorption-type split effective April 1, 2026.

Astemo aims to further strengthen its brand and become a leading company in electrification and intelligence of mobility in the SDV^*1 age. Beyond the In-Car domain—which includes electric powertrains, AD/ADAS^*2 technologies, and power control technologies essential for the stable operation of ECUs^*3 supporting software-based control—the company is also advancing energy management technologies in the Out-Car domain, such as its IoV^*4 platform, with a focus on integration with infrastructure and energy supply networks. Among these initiatives, further strengthening power system technologies remains a critical area in supporting next-generation vehicle development.

Astemo will take over from TDK the development of automotive power supply technologies such as DC-DC converters and onboard chargers—for which TDK has built technical reliability through years of practical application, mass production, and market deployment—along with the supporting development personnel and assets for a new development business. This will expand Astemo’s technological foundation in the electrification domain, as well as enable the advancement and restructuring of energy management technologies within the In-Car domain and Out-Car domain, which encompasses integration with charging infrastructure and power grids. In particular, the advancement of power conversion technology increases design flexibility for E/E^*5 architectures, and is crucial to realizing next-generation energy management technologies such as V2X^*6 and integration with external energy sources. Through this transfer, Astemo will accelerate its efforts to provide the advanced energy management technologies required for next-generation vehicles in both the In-Car and Out-Car domains.

In connection with this Matter, Astemo will pay 4.3 billion yen to TDK for the rights and obligations being transferred.

Through this opportunity to accelerate the optimization of power supply and control technologies in both In-Car and Out-Car domains, as well as the advancement of energy management technologies, Astemo will contribute to the evolution of next-generation mobility required in the SDV era.
