  • Expansion of cloud solutions through the Cloud Business Center leveraging AWS Advanced Tier Partner status
  • Achieving both revenue growth and improved profitability and maximizing group synergies as the final year of Phase 2 of the 2030 long-term vision

Risks

  • Increasing difficulty in securing talent in the information services industry (intensifying recruitment competition in the Tokyo metropolitan area and other major urban areas)
  • Pressure on profit margins from increased goodwill amortization (¥136 million in FY2026 ending March 2026) and higher administrative costs
  • Risk of revenue concentration among major customers (TEPCO Systems Corporation, NEC Corporation, Hitachi, Ltd.)
  • Uncertainty over the economic outlook due to prolonged geopolitical risk and uncertainty over U.S. trade policy direction
  • Rising cost of sales due to increased labor costs and outsourcing processing costs (cost of sales of ¥8,479 million in FY2026 ending March 2026, up 23.3% year on year)
