Key Products

product

Growth Drivers

  • Increase in equipment-related sales accompanying the launch of new models by the principal customer (Honda Motor Co., Ltd. group)
  • Reduction in manufacturing costs through structural reforms (lower amortization burden following the drop-off of impairment losses recorded in the prior period)
  • Promotion of appropriate pricing
  • Increase in order intake and order backlog (order intake of ¥49,735 million, up 103.9% year on year; order backlog of ¥4,416 million, up 141.5% year on year)
  • Profitability improvement measures for existing businesses under the medium-term management plan "Change 2027"

Risks

  • Risk of revenue concentration in the principal customer (Honda Motor Co., Ltd. group), which accounts for the majority of the group's total revenue
  • Risk of temporary decline in Automobile Frame production volume for the principal customer due to semiconductor supply shortages
  • Risk of structural changes in demand for existing products accompanying the CASE revolution (electrification and automation) in the automotive industry
  • Risk of profit pressure from rising domestic production costs (labor costs, energy costs, etc.)
  • Foreign exchange risk (deterioration in export profitability due to yen appreciation)
