Growth Drivers

  • Market expansion through collaboration with overseas GTOSS members (expanded to 11 companies in Asia and 4 in North America, with progress in product sales and rentals in Europe, India, Singapore, and California)
  • Increase in projects adopting the method against a backdrop of domestic infrastructure aging, national resilience measures, and disaster recovery demand
  • Hat-shaped steel sheet pile press-in at 900mm width was listed in the Ministry of Land, Infrastructure, Transport and Tourism's civil engineering cost estimation standards, certified as a standard method for public works
  • Expansion of standard machine sales through the introduction of the new "Silent Piler ST400SX" model
  • Responding to customers' labor-saving and workforce efficiency needs through the provision of G-Lab and DX applications
  • Creation of new markets utilizing a cooperation agreement with a major precast concrete manufacturer in India

Risks

  • Decline in domestic users' capital investment sentiment due to rising construction costs, decreased construction volume, and shortage of skilled labor
  • Rising cost ratio due to soaring procurement prices for raw materials and parts
  • Pressure on profitability due to increased research and development expenses and personnel costs
  • Uncertainty regarding overseas business outlook due to trends in Middle East affairs and U.S. tariff policy
  • Risk related to relationships with local partners in overseas expansion (a special loss of ¥812 million was recorded in connection with a litigation settlement with a former overseas consolidated subsidiary)
  • Risk of demand fluctuation in domestic standard machine sales (customers' capital investment continues to be cautious)
