Business Model
Domestically, the company provides order-based consulting services such as geological surveys, design, monitoring, and disaster prevention planning, with public works accounting for the majority of sales. Overseas, it also generates product-based revenue by manufacturing and selling measurement instruments such as seismographs, ground-penetrating radar, and magnetic survey equipment. Of net sales of ¥76,285 million for FY2025 (ending December 2025), the three segments are diversified as follows: Disaster Prevention & Infrastructure 39.3%, Environment & Energy 39.0%, and International 21.6%. The company invests ¥2,403 million in R&D expenses to maintain its technological advantage.
Company Strengths
Against the backdrop of the government's 'National Resilience Implementation Medium-Term Plan (2026–2030, total scale of over ¥20 trillion),' specialized technologies in geology, ground surveying, observation, monitoring, and disaster risk assessment translate directly into demand. Orders received for the Disaster Prevention/Infrastructure business in FY2025 (ending December 2025) showed strong growth, reaching ¥32,803 million (111.9% year-on-year).
The Environment/Energy business achieved net sales of ¥29,759 million, operating profit of ¥3,073 million, and an operating margin of 10.3% in FY2025 (ending December 2025). The company holds the top domestic market share in seabed ground survey technology for offshore wind power and also boasts the top domestic market share in disaster waste treatment planning services. It has become a highly profitable segment driving the group's overall earnings.
The ground information database accumulated over 67 years since the company's founding in 1957 is being developed into a 'Ground Information Data Platform.' Overseas, the group has 13 measuring instrument manufacturers and service companies in the United States, United Kingdom, France, Singapore, and elsewhere, and owns global brands such as KINEMETRICS (seismometers), GSSI (ground-penetrating radar), and GEOMETRICS (magnetic survey equipment).
ENVALITH's Perspective
Performance Trend
Revenue increased for five consecutive fiscal periods, from ¥51,675 million in FY2021 to ¥76,285 million in FY2025, but the full-year forecast for FY2026 (ending December 2026) stands at ¥75,000 million (down 1.7% year on year), marking the first projected decline in revenue. In Q1 FY2026 (ending December 2026), revenue was ¥20,189 million (down 0.7% year on year), operating profit was ¥2,692 million (down 11.9%), and profit attributable to owners of parent was ¥1,929 million (down 19.7%), representing significant declines across all profit lines. External factors included the tapering off of demand related to recovery from the Noto Peninsula earthquake, a postponement in the schedule for detailed survey projects related to offshore wind power generation, and sluggishness in international business due to geopolitical risk, all of which occurred simultaneously. Selling, general and administrative expenses increased to ¥4,697 million (from ¥4,504 million in the same period of the previous year), and rising cost pressures are also squeezing profit margins.
Growth Strategy
Leveraging tailwinds from national resilience and decarbonization policies, the company aims to deepen its three-segment strategy and achieve an ROE of 6% and an operating profit margin of 8%.
Improving gross profit margin through strengthening the functions of regional offices, optimizing staff allocation, and enhancing productivity. In Q1 of FY2026 (ending December 2026), operating profit reached ¥2,423 million (161.5% year-on-year), demonstrating the effects of these measures in concrete figures. The company will continue to capture medium- to long-term public works demand underpinned by the National Resilience Implementation Medium-Term Plan (2026–2030, totaling over ¥20 trillion).
Promoting order growth in offshore wind power generation (JOGMEC basic surveys), environmental restoration support, and decarbonization-related fields. Orders received in Q1 of FY2026 (ending December 2026) increased 110.5% year-on-year, and the focus going forward is on revenue conversion as detailed survey projects move into full-scale execution. Strengthening cost management for projects with front-loaded costs is also a challenge.
Working to recover order intake at overseas subsidiaries, mainly in the United States and Singapore. Orders received in Q1 of FY2026 (ending December 2026) rose 135.7% year-on-year, showing signs of bottoming out, but revenue remained at 87.7% of the prior-year level, and the operating loss widened to ¥428 million. Resolving timing gaps in product shipments and work progress, as well as addressing geopolitical risk, are urgent priorities.
The annual dividend forecast for FY2026 (ending December 2026) is ¥110 (¥55 at the second-quarter end and ¥55 at year-end), maintaining the same level as the previous fiscal year. Backed by a solid financial foundation with an equity ratio of 71.3% and cash and deposits of ¥23,634 million, the company plans to continue stable dividends even amid fluctuations in business performance.
