Business Details
Provides semiconductor design services centered on system LSI, embedded software development for IoT devices and other equipment, and hardware design services for various devices. Primary target areas include semiconductor fields such as CMOS image sensors, mechanical design for communication equipment components, design and development of medical devices, and CASE-related embedded software. Centered on technical support for major IT manufacturers, the segment aims to provide edge computing-compatible processor development and control equipment technology for the connected society.
Recent Overview
Net sales rose 11.9% year on year on growth in semiconductor, communications, and medical orders, but profit margin declined
In the System Core business for FY2026 (ending March 2026), orders grew in semiconductor fields such as image sensors, mechanical design for communication equipment components, and embedded software development, while medical device design and development work also trended steadily, resulting in net sales of ¥4,675 million (up 11.9% year on year). On the other hand, segment profit was only ¥1,098 million (up 1.8% year on year), a modest increase relative to the growth in sales, causing segment profit margin to decline from 25.8% in the prior period to 23.5%. This appears to reflect margin pressure from expanded human capital investment, including salary increases.
Key Products
Growth Drivers
- Expanding demand for CMOS image sensors (driven by wider adoption of driver-assistance systems and increased demand for automotive semiconductors)
- Growth in orders for CASE-related embedded software development projects
- Steady trends in mechanical design for communication equipment components and design/development of medical devices
- Strengthened capabilities for edge computing-compatible processor development technology
- Profitability improvement through contract unit price revisions and a shift toward growth areas
Risks
- Risk of earnings volatility due to excessive concentration on/dependence on specific fields or clients (stated explicitly in the securities report)
- Rising personnel costs and difficulty in hiring due to tight supply-demand conditions for IT talent
- Fluctuations in semiconductor market demand (dependent on customers' capital expenditure cycles)
- Ongoing burden of talent development and technology investment needed to keep pace with the speed of technological innovation
- Declining trend in segment profit margin (23.5% in FY2026 ending March 2026, deteriorating from 25.8% in the prior period)
