Growth Drivers

  • Robust orders for large-scale new construction projects for research facilities and hospital facilities in the Tokyo metropolitan area and the Hokuriku region (orders received of ¥24,713 million, up 31.1% year on year, a record high for the second consecutive year)
  • Improvement in the leading indicator for next fiscal year's net sales due to the accumulation of an order backlog of ¥22,070 million (up 22.4% year on year)
  • Enhanced competitive advantage through high-value-added projects such as proposals for ZEB-compliant, high-efficiency HVAC equipment utilizing ICT/IoT
  • Expansion of orders for modeling operations for redevelopment, logistics facilities, and data centers by the Vietnam subsidiary's BIM Engineering Center (over 250 BIM engineers)
  • Rationalization and efficiency through ICT utilization driven by DX promotion, and accumulation of on-site operational know-how and data
  • Securing stable orders through years of accumulated construction equipment know-how in the Hokuriku region and expanded maintenance services

Risks

  • Next fiscal year's (FY2027, ending March 2027) earnings forecast anticipates a slight decrease in operating profit to ¥2,300 million (down 0.9% year on year), with temporary disruptions in material procurement due to supply chain disruptions stemming from Middle East tensions and short-term delays in some projects
  • Chronic labor shortages against a backdrop of an aging workforce and a lack of new young entrants in the construction industry, as well as constraints on construction capacity due to overtime work regulations
  • Risk of increased construction costs due to rising raw material prices, energy costs, and logistics costs
  • Increased costs for responding to environmentally friendly buildings against a backdrop of energy conservation and decarbonization trends
  • Indirect impact of US tariff policy trends and geopolitical risks on trends in the construction-related industry
