Recent Overview

Achieved revenue and substantial profit growth driven by strong sales of two-wheel vehicle instrumentation and cost improvements.

In FY2026 (ending March 2026), the Automotive Components Business posted revenue of ¥267,236 million (up 3.5% year on year) and operating profit of ¥8,514 million (up 24.0% year on year). Strong sales of two-wheel vehicle instrumentation, mainly in ASEAN, India, and Brazil, drove revenue growth. Four-wheel vehicle products declined due to weak sales of Japanese and European vehicles in the Chinese market, but increased sales of construction machinery instrumentation also contributed to profit. The operating profit margin improved due to progress in supply chain reform and cost reduction activities. As a subsequent event, on April 20, 2026, the company resolved to make Toyo Denso Co., Ltd., which handles switches for four-wheel and two-wheel vehicles, a wholly owned subsidiary (acquisition consideration of ¥49,850 million, scheduled for October 1, 2026), aiming to expand its product portfolio in the HMI domain and create technological synergies.

Key Products

Growth Drivers

• Expanding demand for two-wheel vehicle instrumentation centered on ASEAN, India, and South America (Brazil) (accelerating sales in Global South regions)
• Revenue expansion through the introduction of high-value-added new Head-Up Display models and unit price increases through the development of advanced functions
• Expansion of the product portfolio in the HMI domain, technological synergies, and mutual utilization of customer bases through the full consolidation of Toyo Denso as a subsidiary
• Cost reduction through supply chain reforms such as accelerating local production for local consumption and optimizing production layouts, as well as product specification reviews
• Profit contribution from increased sales of instrumentation for construction machinery

Risks

• Risk of declining sales of Instrumentation for Four-Wheel Vehicles due to continued weak sales of Japanese and European vehicles in the Chinese market
• Risk of impact on the automotive industry and economic slowdown due to U.S. trade policy (tariff increases)
• Decrease in the yen-converted value of overseas revenue due to yen appreciation (foreign exchange translation risk)
• Profitability challenges in the European business (risk of delayed cost improvement for fixed cost burden and unprofitable models)
• Risk of revenue concentration on the Honda Motor Co., Ltd. group
• Risk of integration costs and goodwill recognition associated with making Toyo Denso a subsidiary, and risk that expected synergies will not be realized
