Business Details
Handles the development, manufacture, sales, construction and engineering of centralized monitoring/control systems and electrical equipment for power plants and substations, distribution line automatic control systems/distribution equipment, power business IT systems, Smart Security Systems, and other products. The main customer is Kyushu Electric Power Co., Inc. (sales of ¥7,348 million in FY2025 (ending December 2025), 23.4% of total company sales). In addition to domestic operations, the company also conducts business in China through Dalian Seiko Electric Control Co., Ltd. and Beijing Seiko United Electric Co., Ltd.
Recent Overview
Sales and profit both declined year-on-year in Q1 FY2026 due to sluggish distribution equipment demand
In Q1 FY2026 (ending December 2026) (January to March 2026), while integrated control center systems (OT) and Smart Security Systems such as remote monitoring systems in the information/control field performed steadily, the distribution equipment field was sluggish. As a result, sales were ¥2,434 million (down 2.7% year-on-year) and segment profit was ¥479 million (down 14.6% year-on-year), with the segment profit margin declining to 19.7% (from 22.5% in the same period of the previous year).
Key Products
Growth Drivers
- Steady demand for integrated control center systems (OT) and Smart Security Systems in the information/control field
- Expectations of expanded power infrastructure investment amid AI data center construction and rising power demand
- Promotion of the digital-first strategy (OT×IT fusion) under the medium-term management plan SEIKO IC2026
- Steady demand for renewal of aging social infrastructure and resilient public investment for national land resilience
- Improved sales visibility from the accumulation of order backlog (¥6,667 million at end of FY2025, up 4.4% year-on-year)
Risks
- Risk of continued weak demand for distribution equipment products (sluggish in both FY2025 and Q1 FY2026)
- Sales dependence on the major customer Kyushu Electric Power Co., Inc. (sales of ¥7,348 million in FY2025, 23.4% of total company)
- Restraint of customer capital expenditure due to geopolitical risk and persistently high resource/energy costs
- Risk of deteriorating business environment at Chinese subsidiaries (Dalian Seiko Electric Control, Beijing Seiko United Electric)
- Uncertainty in progress-rate estimates for construction/engineering projects (a significant accounting estimate)
