OTEC CORPORATION
1736・Standard Market・Construction
Business
OTEC Corporation was founded in 1948 and is listed on the Standard Market of the Tokyo Stock Exchange as a construction equipment-related company. In its core Environmental Systems business, the company handles the design, construction, and maintenance of automatic control systems and radiant heating/cooling systems for new and existing buildings, expanding nationwide on the basis of its distributor agreement with Azbil Corporation. In its Piping and Equipment Materials business, it operates as a specialized trading company for sanitary ware, valves, steel pipes, and similar products, selling to equipment installation contractors and secondary wholesalers. With a group structure including 7 consolidated subsidiaries, the company captures construction demand from both public and private sectors. Consolidated net sales for FY2026 (ending March 2026) were ¥33,722 million.
Business Model
The Environmental Systems business handles three work categories—new installation, existing facility work, and maintenance—and enjoys a high level of customer lock-in, with the ratio of negotiated (tokumei) orders reaching nearly 100% in both new installation and existing facility work. Backlog of ¥13,124 million provides visibility into next-period sales. The Piping Equipment and Materials business sells a wide range of products, including those from affiliated companies, as a specialized trading company, generating synergies with the Environmental Systems business through shared customer bases. Combined, the two businesses have improved gross profit margin while achieving an operating margin of 15.1% (FY2026, ending March 2026).
Company Strengths
In the Environmental Systems business, the ratio of sole-source (negotiated) orders for new and existing facility construction reached 100.0% and 99.6%, respectively, in FY2026 (ending March 2026). Years of construction track record and accumulated project data underpin the company's proposal capabilities, building customer relationships that are difficult for competitors to replicate in a short period. Backlog of ¥13,124 million (up 22.6% year on year) enhances visibility into next-period sales.
Operating profit in the Environmental Systems business for FY2026 (ending March 2026) reached ¥6,075 million, with an operating margin of 27.9%. Thorough cost management and an increase in completed construction revenue from existing facility work (high-margin, up 17.5% year on year) pushed up the margin, marking a significant improvement from the operating margin in FY2025 (ended March 2025). This earnings structure supports the majority of profit for the group as a whole.
Since the agreement was concluded in 1961, the company has maintained a distributorship agreement with Azbil Corporation for air-conditioning automatic control equipment and related products for over 60 years, ensuring stable procurement of key equipment and technical support. This long-term relationship represents a competitive advantage that new entrants cannot replicate in a short period, forming the foundation of the Environmental Systems business's order-taking and construction capabilities.
ENVALITH's Perspective
Performance Trend
Revenue increased 32.7% over five fiscal periods, from ¥25,410 million in FY2022 (ended March 2022) to ¥33,722 million in FY2026 (ending March 2026). In particular, operating profit expanded roughly 2.5-fold over two periods, from ¥2,027 million in FY2024 (ended March 2024) to ¥5,084 million in FY2026 (ending March 2026), with the operating margin reaching 15.1% (up from 12.8% in the prior period). This was driven mainly by improvement in gross margin, supported by expansion of retrofit and maintenance construction work in the Environmental Systems business and an improved construction mix. External factors also provided tailwinds, including resilient public investment and rising private-sector labor-saving investment. Cash and cash equivalents stood at ¥10,340 million, a record high. For FY2027 (ending March 2027), profit growth is expected to continue, but at a slower pace (operating profit up 6.2%).
Growth Strategy
Advancing on two fronts: capturing decarbonization demand in the environmental systems business and reforming the profit structure of the piping materials & equipment business.
Through strengthened proposal capabilities leveraging construction project data and DX promotion, along with enhanced support systems for field engineers, the company achieved order intake of ¥23,337 million (up 23.5% year on year) and a backlog of ¥13,124 million (up 22.6% year on year). Orders for new construction work expanded sharply, up 47.1% year on year, significantly improving visibility into revenue for the next period.
The company is promoting operational efficiency in order management, inventory management, and customer support through enhanced functionality of its product sales site "O/tegaru." In FY2026 (ending March 2026), sales increased 5.1%, but insufficient pass-through of rising cost of sales to prices resulted in an operating loss of ¥80 million. Achieving price pass-through and improving the product mix (valves up 13.6% year on year, etc.) are key to profit recovery.
Effective April 6, 2026, the company made K.T.S Co., Ltd. (test-run adjustment of air conditioning automatic control systems, inspection and repair of control equipment, and control program design) a wholly owned subsidiary for ¥200 million (funded internally). This strengthens the test-run adjustment and maintenance system in the Tokyo metropolitan area and expands the company's capability to provide integrated services from design through test-run adjustment and maintenance.
The company changed its dividend policy to "whichever is higher between a consolidated payout ratio of 40% or more, or DOE of 4.8% or more," and plans an annual dividend of ¥98 for FY2027 (ending March 2027) (payout ratio forecast of 40.0%). Combined with the 1-for-3 stock split implemented in April 2025, this clearly signals expansion of the investor base and a more proactive approach to shareholder returns.
