Recent Overview

Sales fell 12.7%, but operating profit remained nearly flat due to efficiency improvement efforts

In FY2026 (ending March 2026), sales were ¥38,792 million (down 12.7% year on year) due to a decrease in large-scale new-construction-related projects. On the other hand, thanks to efforts to improve production efficiency, construction profitability, and work-style reform, operating profit remained nearly flat at ¥3,976 million (down 0.6% year on year). Orders received declined significantly to ¥30,706 million (down 31.8% year on year) amid a challenging business environment, and the order backlog also shrank to ¥55,116 million.

Growth Drivers

  • Stable earnings base through steady recognition of sales from the order backlog of ¥55,116 million (end of FY2026, ending March 2026)
  • Mid- to long-term demand from continued ordering of expressway large-scale renewal and maintenance work (business scale of approximately ¥7 trillion)
  • Robust demand for railway-related construction such as terminal station redevelopment and continuous grade separation projects in the Tokyo metropolitan area
  • Progress on highly complex major projects such as the Osaka Bay Route Western Extension, the Meishin Bay Route Connecting Bridge, and the Shimonoseki-Kitakyushu Road
  • Continued efforts to improve production efficiency, construction profitability, and operational efficiency through DX
  • Expectations for recovery in the market environment, including new-construction-related demand, driven by the comprehensive economic package aimed at realizing a "strong economy"

Risks

  • Deterioration of the order environment due to a decline in new bridge construction orders (expected to fall to a scale of ¥1,800 million in FY2027, ending March 2027)
  • The continuing trend of shrinking new contract scale in large-scale renewal and maintenance-related work
  • Impact on construction profitability from trends in the price of steel materials, a key raw material
  • Declining order volume on a workload basis due to soaring construction unit prices resulting from wage and price increases
  • Uncertainty in order volume due to fluctuations in public works budgets of national and local governments
  • Risk of temporary earnings decline due to the long lag between order receipt and revenue/profit recognition
