Japan's Denso has submitted a 1.3 trillion yen takeover bid for Rohm, planning to acquire all of its shares through a TOB. This move will strengthen its market position in the power semiconductor sector, especially in the electric vehicle and data center fields, marking a shift for Japanese companies from collaboration to mergers and acquisitions.

Nippon Denso has made a takeover bid for semiconductor giant Rohm. The move is believed to involve acquiring all shares through a tender offer (TOB). The acquisition is expected to reach approximately 1.3 trillion yen. If successful, it would establish a major presence in the power semiconductors sector used for pure electric vehicles (EVs) and data center power control in Japan. Previously, industry restructuring centered on cooperation will shift toward elimination through mergers and acquisitions.

In the power semiconductor field, Japanese companies have traditional advantages, but with the rise of Chinese firms, capacity among Japanese companies has become oversupplied. Japan’s Ministry of Economy, Trade and Industry has also urged companies to restructure. Previously, Denso collaborated separately with Fuji Electric and Rohm with Toshiba; now, the framework may undergo significant changes.

Denso and Rohm announced in May 2025 that they would cooperate in the semiconductor sector, planning to jointly develop analog semiconductors for controlling sensors in pure electric vehicles. Denso acquired a 0.3% stake in Rohm through this partnership. By July of the same year, they further increased their shareholding, raising their investment to nearly 5%.
