Business

Tekken Corporation is a general construction company founded in 1944, with civil engineering works and building construction as its core businesses, alongside real estate and ancillary businesses. Its core strength lies in construction techniques for work in close proximity to railways, and its main customers include railway operators such as East Japan Railway Company (JR East), government agencies, and private companies. Consolidated net sales for FY2026 (ending March 2026) were ¥179,825 million, with civil engineering works (¥91,165 million) and building construction (¥84,080 million) accounting for approximately 97% of sales. The company holds large-scale railway infrastructure projects on order, including construction of the new Haneda Airport access line and the Shinagawa Station north entrance plaza, and conducts business as a group comprising 10 subsidiaries and 3 affiliated companies.

Business Model

The company's core business model is order-based production contracting for civil engineering and construction works, generating revenue through a cycle of order receipt → construction → completion and delivery. It maintains a stable customer base, with sales to JR East accounting for approximately 24% of consolidated net sales, and aims to improve profit margins through rigorous selective order-taking and cost reduction via centralized management. The real estate business (net sales of ¥5,002 million) and ancillary businesses serve as complementary revenue sources.

Company Strengths

Completed construction revenue from East Japan Railway Company reached ¥41,658 million (24.0% of total completed construction revenue) in FY2026 (ending March 2026), expanding from ¥39,264 million (22.0%) in the prior period. The company holds large-scale projects in its order backlog, including the Haneda Airport Access Line and the new Nasushiobara rolling stock depot, with technical expertise cultivated through construction adjacent to operating railways serving as a barrier to entry for competitors.

Order backlog as of the end of March 2026 stood at ¥329,481 million (civil engineering ¥188,403 million; building construction ¥141,078 million), up 18.4% from ¥278,222 million at the end of the prior period. Multi-year large-scale projects such as the Haneda Airport Access Line (scheduled for completion in February 2029) and the Tohoku Shinkansen Nasushiobara rolling stock depot (scheduled for completion in February 2033) have accumulated, providing visibility into the medium-term revenue base.

R&D expenses in FY2026 (ending March 2026) totaled ¥1,231 million (civil engineering ¥1,132 million; building construction ¥98 million). The company has built up a track record of proprietary technology development, including a track surface monitoring system utilizing point cloud data (jointly developed with JR East), machine guidance technology for non-GNSS environments, and a BIM-based concrete placement simulation system, giving it a technological foundation that enhances both construction efficiency and safety.

ENVALITH's Perspective

Operating profit showed a strong recovery, rising from ¥3,459 million in FY2025 (ended March 2025) to ¥5,622 million in FY2026 (ended March 2026), up 62.5% year on year. However, operating cash flow remained negative at ¥13,889 million (an improvement from negative ¥20,285 million in the prior period), and the structure of covering this shortfall with financing cash flow (net increase in borrowings of ¥19,752 million) continued. Interest-bearing debt increased sharply, with short-term borrowings at ¥53,353 million (prior period: ¥39,845 million) and long-term borrowings at ¥22,326 million (prior period: ¥16,082 million), while interest expense also expanded to ¥1,204 million (prior period: ¥752 million). Increases in trade receivables and inventories accompanying the consumption of the order backlog are putting pressure on working capital, making it a challenge to achieve both earnings improvement and financial soundness simultaneously.

The company has changed its dividend policy from FY2026 onward to target a DOE (dividend on equity ratio) of 4% or higher. The projected dividend for FY2027 (ending March 2027) is ¥223 per share (an increase of ¥53 from ¥170 in the prior period), with a payout ratio of 49.3%. The shift to a DOE-based standard aims to achieve stable dividends less susceptible to earnings volatility; against equity of ¥78,420 million (as of FY2026 (ended March 2026)), a 4% DOE corresponds to a total dividend amount of approximately ¥3,137 million, which leaves sufficient room given the current net profit level (¥5,029 million). However, continuing to increase dividends while operating cash flow remains negative could deepen reliance on borrowing, making sustained improvement in earnings capacity a prerequisite.

As external factors, tariff increases stemming from U.S. trade policy, the surge in crude oil and materials prices amid heightened tensions in the Middle East, and labor shortages resulting from the decline in the number of workers across the construction industry as a whole continue to exert upward pressure on construction costs. The provision for construction contract losses booked in FY2026 (ended March 2026) remained at a high level of ¥1,687 million (prior period: ¥1,684 million), and the international arbitration case related to the South Asian project (with an allowance for doubtful accounts of ¥2,633 million recorded) also remains a potential loss risk. The operating profit forecast for FY2027 (ending March 2027) is a bullish ¥6,600 million (up 17.4% year on year), but achieving this could prove difficult depending on trends in materials and labor costs.

Growth Strategy

Under the updated Medium-Term Management Plan 2028, the company is accelerating enhancement of corporate value through DOE-based management, selective order-taking, and DX promotion.

With the purpose of "Continuing to evolve, for a city that keeps moving," the company has clarified its future vision from six perspectives: social value, customer value, technological evolution, human resource development, organizational culture, and sustainable growth. Having achieved its profit targets ahead of schedule, the plan was updated and financial and non-financial KPIs were revised.

The company has thoroughly pursued selective order-taking with an awareness of its business portfolio, achieving a turnaround to profitability in the building construction segment (from a loss of ¥997 million in the prior period to a profit of ¥1,030 million in the current period). It continues to improve profit productivity through organizational initiatives premised on ensuring quality and thorough safety.

The company has implemented the use of proprietary generative AI and the introduction of ICT construction machinery at railway construction sites. It is promoting business transformation and efficiency improvements to reduce costs and address labor shortages, with R&D expenses trending upward to ¥1,231 million (up from ¥1,101 million in the prior period).

The dividend policy from fiscal year 2026 onward has been changed to a guideline of DOE of 4% or more, achieving stable dividends less susceptible to business fluctuations. The forecast dividend for FY2027 (ending March 2027) is ¥223 per share (an increase of ¥53 year on year). Share buybacks will also be conducted flexibly in consideration of the financial position and market environment.

The company continues to participate in projects laying the groundwork for the future, such as construction of a new Haneda Airport access line and defense-related construction work. In the real estate business, the balance of real estate for sale increased significantly from ¥1,685 million to ¥6,196 million, expanding the pipeline of sale and purchase deals. Investment activities are also being conducted through anonymous partnership investments and other means.
