Recent Overview
Orders declined as Noto recovery demand subsided, but progress on backlog and margin improvement drove higher sales and profit
In Q1 FY2026 (ending December 2026), orders received decreased to ¥7,747 million (91.5% YoY) as demand for Noto Peninsula earthquake disaster recovery response work, which had been at a high level in the prior period, subsided. Meanwhile, steady progress was made on the order backlog carried over from the start of the period, including renewal work for earthquake and volcano observation and monitoring equipment, resulting in a significant increase in sales to ¥9,909 million (117.7% YoY). Gross profit margin improved through efforts to strengthen regional base functions, optimize staffing, and improve productivity, resulting in a significant increase in operating profit to ¥2,423 million (161.5% YoY) compared to the same period of the prior year.
Key Products
Growth Drivers
- Medium- to long-term stable demand for public works backed by the government's 'National Resilience Implementation Medium-Term Plan (2026-2030, total of over ¥20 trillion)'
- Expanding demand for recovery support and disaster prevention-related work amid more frequent and severe natural disasters
- Continued increase in demand for inspection, diagnosis, and maintenance due to progressing aging of social infrastructure
- Improvement in gross profit margin through strengthening regional bases, optimizing staffing, and improving productivity
- Capture of new demand areas such as volcano observation network renewal work
- Strengthening of group structure through the merger of Geo Five Co., Ltd.
Risks
- Risk of decreased orders due to cuts or reviews of public works budgets
- Risk of deteriorating profitability due to engineer shortages and rising labor costs
- Risk of additional costs such as repair expenses related to work completed in prior years
- Risk of demand fluctuation depending on the timing and scale of natural disasters (such as the temporary falloff seen as Noto recovery demand subsides)
- Risk of declining competitiveness due to delays in adopting digital technology and AI
