Key Products

Growth Drivers

• Expansion of development demand related to SDV (Software-Defined Vehicle): the shift toward software-first approaches in the automotive market is accelerating
• Rapid expansion of Software Products (Q1 FY2026, ending December 2026: ¥589 million, up 111.6% year on year)
• Continued expansion of Engineering Services (full year FY2025, ended December 2025: ¥9,874 million, up 11.7% year on year)
• Acquisition of higher value-added projects through advancement of functional safety standard certification
• Increase in order backlog (¥1,698 million, up 21.7% year on year) contributing to sales in future periods
• Expansion of business scope and customer base through consolidation of KMC Holdings (Kyoto Microcomputer Co., Ltd.)
• Increase in sales to Honda Motor Co., Ltd. (from ¥652 million in the prior period to ¥944 million in the current period)

Risks

• Risk of volatility in Software Products sales: in the prior period there was a temporary large licensing revenue item (¥2,305 million), the reversal of which caused a decline to ¥1,652 million for full-year FY2025 (ended December 2025), with uncertainty as to reproducibility
• Cost pressure from continued R&D investment (segment profit margin declined to 7.0% for full-year FY2025, ended December 2025, from 8.2% in the prior period)
• Emergence of customer concentration risk due to a decline in sales to major customer Denso (from ¥2,738 million in the prior period to ¥1,816 million in FY2025, a 33.7% decrease)
• Risk of a global economic slowdown due to sharp exchange rate fluctuations and other factors
• Aggressive business expansion by vendors in emerging countries (intensifying competition)
• Difficulty securing engineers due to a deteriorating hiring environment amid Japan's population decline
