Denso
Denso is a Toyota-group global auto-parts supplier ranked among the world's largest, with FY2025 (year ended March 31, 2025) consolidated revenue of about 7,161.8 billion yen. Roughly half of revenue comes from the Toyota Group, and the business spans five segments: Thermal, Powertrain, Mobility Electronics, Electrification, and Advanced Devices. To handle the shift to electrification it develops its own SiC power semiconductors, plans to invest 500 billion yen in chips by 2030, and is vertically integrating automotive-chip supply through equity stakes in TSMC's Kumamoto fab (JASM) and Coherent's SiC business.

- Coherent Silicon Carbide LLC (SiC 웨이퍼) High confidence
Denso procures SiC wafers, the core material for SiC power semiconductors used in electrification inverters, from Coherent's SiC subsidiary (Silicon Carbide LLC) under a long-term supply arrangement covering 150mm and 200mm wafers.

Until it in-houses SiC, Denso sources automotive chips such as microcontrollers and power semiconductors from ROHM and Renesas, and relies on foundries including TSMC Kumamoto (JASM). The 2021-2022 automotive-chip shortage that forced Toyota production cuts made supply security a strategic priority.Mentions EN Nikkei Asia Published May 1, 2025: Toyota supplier Denso to invest $3.3bn in chip businessMentions KO Sisa Journal e Published Oct 27, 2023: Toyota's Denso to invest 4.5 trillion won in semiconductors

Denso operates across Nikkei 225, Auto parts, Toyota-group, SiC in-housing. It is -8.9% in 2026. The stock (-8.9%) and its demand side (avg -4.5%) are moving in step. Among connected nodes the furthest ahead is Mazda Motor (+1.8%) and the furthest behind is Toyota Motor Corporation (-10.8%). If chain logic explains the gap, the laggard is the next propagation candidate; if not, the link itself deserves a second look.
