Overview
- Denso’s proposal values Rohm at up to ¥1.3 trillion (about $8.2 billion), roughly an 18% premium to its pre-announcement share price.
- Rohm has set up a special committee to assess the bid, and both companies say talks continue with no agreement yet.
- The rationale centers on Rohm’s power semiconductors for EV drivetrains and autonomous functions alongside Denso’s push into systems-on-chip.
- Denso already holds 5% of Rohm and is 20–24% owned by the Toyota Group, which is simplifying governance through a higher Toyota Industries tender and about $19 billion of cross-holding sales.
- A government official cited by the Financial Times pointed to concern over BYD’s growing semiconductor strength, while Japan’s power-chip sector remains fragmented across mid-size players.
