Rohm, a leading semiconductor manufacturer, has revealed that it received an acquisition proposal from Denso, a major auto parts company, on the sixth of the month. Rohm is renowned for its expertise in power semiconductors, which are critical for controlling electricity in automotive and industrial equipment, a sector that Denso is also actively pursuing. The outcome of the potential acquisition remains uncertain, but there is a possibility of enhanced competitiveness through consolidation in this domain.

On the same day, Rohm issued a statement confirming the receipt of Denso's stock acquisition proposal, while Denso also announced that it is considering various strategic options including stock acquisition. Rohm mentioned that it has received multiple proposals from Denso, some of which may involve the acquisition of up to 100% of the company's shares. The board of directors is currently evaluating these proposals in consultation with experts.

Both companies had previously announced a basic agreement on collaboration in the semiconductor field in May 2025. Denso had also increased its stake in Rohm to about 5%. With Rohm's market capitalization exceeding 1 trillion yen, an acquisition involving all shares would certainly be a significant deal exceeding this value. The demand for power semiconductors is expected to rise in the context of the electrification and intelligence of vehicles, making it an area of high competition among domestic manufacturers. A Denso representative indicated the importance of this situation for the future of Japan’s semiconductor industry, describing it as a matter of significant consequence for the country's final bastion in semiconductor technology.
