Business
Metawater Co., Ltd. is a comprehensive water environment engineering company established in 2008 through the integration of NGK Corporation and Fuji Electric's water environment divisions. Domestically, the company handles the design, construction, and maintenance of mechanical equipment (Environmental Engineering Business) and electrical equipment (System Solutions Business) for water purification plants, sewage treatment plants, and resource recycling facilities, as well as direct operation of facilities (Operations Business). Overseas, the company operates in the reclaimed water and advanced treatment process markets through subsidiaries in North America (Aqua-Aerobic Systems, Wigen Companies, Schwing Bioset) and Europe (Rood Wit Blauw Water, E&P Anlagenbau). Its primary customers are government agencies (accounting for over 90% of order volume), and consolidated net sales for FY2026 (ending March 2026) reached ¥209,844 million.
Business Model
The business is centered on multi-year construction contracts spanning order intake through revenue recognition, and the order backlog at the end of FY2026 (ending March 2026) stood at ¥389,299 million (up 22.2% year on year), securing strong revenue visibility. In the Operations Business, stable recurring revenue is accumulated through long-term concession and PFI contracts.

Performance Trend
Revenue grew for five consecutive fiscal years, from ¥135,557 million in FY2022 (ended March 2022) to ¥209,844 million in FY2026 (ending March 2026), with the most recent period's growth rate accelerating to +17.2%.

The Overseas Business led growth with sales up +50.4% year on year, while the Environmental Engineering Business also saw a sharp recovery in operating profit, up +92.3% year on year. As an external factor, foreign exchange gains of ¥621 million from yen depreciation boosted ordinary profit.

Growth Strategy
Significantly revised Medium-Term Management Plan 2027 upward, driving growth across the four business segments and expanding overseas M&A and public-private partnerships
The company is now expected to significantly exceed its original targets (net sales of ¥200.0 billion, operating profit of ¥13.0 billion), and has revised its FY2028 (ending March 2028) targets to net sales of ¥245.0 billion, operating profit of ¥16.5 billion, net income of ¥11.0 billion, and ROE of 11% or higher. The accumulation of the order backlog underpins sales contributions from the next fiscal year onward.
Schwing Bioset, Inc. was newly consolidated in April 2025, securing a product and sales network foundation in the U.S. sludge treatment market. The company is promoting synergy creation among its North American subsidiaries, and overseas business net sales expanded rapidly to ¥56,759 million in FY2026 (ending March 2026) (up 50.4% year on year). The order backlog of ¥55,676 million (up 30.0% year on year) supports sales in the coming fiscal years.
Against the backdrop of the expanded introduction of "Water PPP" based on the Cabinet Office's PPP/PFI Promotion Action Plan, the company is promoting the acquisition of new projects in the Operations Business and Environmental Engineering Business. The order backlog of the Operations Business increased to ¥118,120 million (up 14.7% year on year), advancing the strengthening of a long-term stable earnings base.
As a key initiative of Medium-Term Management Plan 2027, the company is promoting human capital investment and DX investment. It is expanding sales of WBC (Water Business Cloud), reforming engineering methods through ICT utilization, and responding to demand for monitoring system migration. J-ESOP (Employee Stock Ownership Trust) was introduced in February 2026 to strengthen employee incentives.
The company conducted a tender offer for Suido Kiko Kaisha, Ltd. from February to March 2026, acquiring 34.8% of its total issued shares to make it an equity-method affiliate. This aims to strengthen business collaboration in the manufacturing and sales of water treatment machinery and equipment.
