Growth Drivers

  • Continued favorable performance of communication quality improvement construction (mobile) in the NTT facility business
  • Increased construction volume due to the shift of facilities from metal to fiber-optic lines (10G-compatible)
  • Expanding demand for large-scale data center construction, mainly in the Tokyo metropolitan area
  • Capturing demand for large-scale system infrastructure renewal and AI-related investment in the IT Solutions Business
  • Improved profit margins through operational efficiency and productivity gains via DX utilization
  • Strengthened construction capabilities through inter-group collaboration (flexible response to large-scale data center and communication quality improvement construction)
  • Acceleration of overseas market expansion through the establishment of the Indonesia branch
  • Demand for social infrastructure such as renewable energy-related construction and undergrounding of power lines

Risks

  • Risk of customer concentration in the NTT Group (Nippon Telegraph and Telephone East Corporation is a major customer accounting for a significant portion of consolidated net sales)
  • Risk of order fluctuations due to changes in telecom carriers' capital expenditure policies
  • Occurrence of impairment losses on fixed assets (¥64 million recorded in the Nippon COMSYS Group in the current period)
  • Impact on construction execution capacity due to difficulty securing personnel and shortage of engineers
  • Risk of rising construction costs due to soaring energy and raw material prices
  • Risk of construction delays and profitability deterioration on large-scale projects
