Business Model
A public-sector order-based business model in which three ministries and agencies—the Ministry of Land, Infrastructure, Transport and Tourism, the Ministry of Defense, and the Ministry of the Environment—account for over approximately 50% of net sales. Government budgets related to disaster prevention/mitigation and national resilience serve as the primary source of demand, and revenue stability is secured by building up the order backlog (¥14,269 million). The environmental consulting business maintains a profit margin of 11.9% and the construction consulting business a profit margin of 15.2%, sustaining a reasonable level of profitability through differentiation via specialized technology. The real estate leasing business (profit margin exceeding 70%) supplements this with stable cash flow.
Company Strengths

Sales to the Ministry of Defense grew 8.1% year on year, and defense-related operations are beginning to function as a new growth pillar.

ENVALITH's Perspective
Performance Trend
Over the past five fiscal periods, revenue has followed a moderate growth trend, rising from ¥20,624 million in FY2021 to ¥24,616 million in FY2025. In the first quarter of FY2026 (ending December 2026), revenue was ¥7,001 million (up 5.7% year on year), operating profit was ¥1,264 million (up 7.6%), ordinary profit was ¥1,289 million (up 8.1%), and quarterly net income attributable to owners of the parent was ¥891 million (up 10.3%), with all profit metrics exceeding the prior-year quarter. As an external tailwind, the FY2025 government budget's emphasis on disaster prevention/mitigation and decarbonization fields provided support, with renewable energy-related environmental assessments and large-scale marine environmental surveys driving revenue growth. The full-year earnings forecast (revenue of ¥25,700 million, operating profit of ¥3,400 million) remains unchanged from the previous announcement.
