DENSO's Reported ¥1.3T Bid for ROHM
Japanese auto parts giant DENSO has reportedly made a buyout offer for semiconductor firm ROHM, valuing it at around ¥1.3 trillion ($8.7B USD). The move signals major consolidation in the chip sector, driven by surging demand for automotive and AI applications.
This takeover bid follows a deepening alliance between the two firms. DENSO and ROHM formalized a strategic partnership in May 2025, building on a long-standing collaboration in developing automotive semiconductors. As part of that earlier agreement, the companies were already considering strengthening their capital relationship to solidify the partnership. The move is a direct play to vertically integrate a critical part of the electric vehicle supply chain. ROHM is a leader in power semiconductors, particularly those using silicon carbide (SiC), which are essential for improving the efficiency of EV inverters. DENSO has explicitly identified semiconductors as a key strategic area to enable next-generation systems for electrification and autonomous driving. As of September 2025, DENSO already held an equity stake of approximately 5% in ROHM. The current proposal, reportedly made in February 2026 or earlier, would involve acquiring the remaining shares to take full control of the semiconductor manufacturer. In response to the bid, ROHM has confirmed it received the proposal and has formed a special committee to formally assess the offer. Sources suggest that if the current offer is rejected by ROHM's board, DENSO may consider pursuing a hostile takeover to complete the transaction.
