DENSO Corporation (DNZOF)

How it makes money

DENSO sells parts as an original-equipment supplier under contracts tied to specific vehicle models, so revenue tracks how many cars carmakers actually build and how much content DENSO wins on each one. Prices are negotiated per component and typically decline over a model's life under automakers' cost-reduction pressure, so DENSO depends on new wins and efficiency gains to protect margins.

DENSO's revenue follows global vehicle production, which rises and falls with consumer confidence, credit conditions and automakers' own inventory cycles. Because contracts are tied to specific models, a model's production cut or delay shows up directly in DENSO's results with little lag.

Key risks

• Dependence on Toyota group sales — DENSO discloses that fluctuations in Toyota group sales could materially affect its performance, even though it states it negotiates terms with Toyota group companies on the same basis as with other customers.
• Semiconductor and supply-chain fragility — Recent shortages of automotive semiconductors exposed how dependent DENSO's production is on a resilient global supply chain; a disruption at a chip or raw-material supplier can constrain output across several of its product lines at once.
• Competition in electrification components — As electrification becomes central to vehicle powertrains, DENSO faces rivals such as LG Magna e-Powertrain and CATL in inverters and battery-related systems, an area where it does not hold the same long incumbency it has in traditional components.

Top customers account for 48.6% of revenue

For the fiscal year ended March 2026, sales to the Toyota group accounted for 48.6% of DENSO's net sales, according to the company's own related-party disclosure. Toyota also holds roughly 22% of DENSO's voting rights.
