Key Products
Growth Drivers
- Sales expansion supported by solid demand trends in the domestic Japanese truck market
- Profit margin improvement through ongoing product mix improvement and continued promotion of production efficiency and cost reduction activities
- Maintenance and strengthening of production capacity through expanded capital expenditures (from ¥667 million in the prior period to ¥847 million in the current period)
- A profit growth plan centered on the Japan segment under the new medium-term management plan "TRS Vision-2030"
- Plans for increased revenue and profit in the Japan segment in the next fiscal year (FY2027, ending March 2027), assuming continued solid trends in the commercial vehicle market
Risks
- The industrial and construction machinery market is expected to remain at a level similar to the current fiscal year, limiting room for growth
- Structural change risk in the truck and construction machinery markets due to accelerating carbon neutrality initiatives (shift to EVs/NEVs)
- Risk of sales concentration on the main customer, Isuzu Motors
- Continuation of a challenging cost environment, including fluctuations in raw material prices and rising labor costs due to wage increases
- Indirect impacts from geopolitical risks, monetary policy trends, and foreign exchange rate fluctuations
