Key Products
Growth Drivers
- Increased sales to the electronics/semiconductor industry driven by expanding demand for AI and advanced semiconductor processing tools and a recovery in memory production
- Recovery in demand for ceramics and bearing tools for semiconductor manufacturing equipment in the machinery industry
- Increased sales of aircraft-related tools for the transportation equipment industry due to a recovery in aircraft demand
- Improved gross margin through product price revisions (price increases) in response to rising prices
- Concentrated investment in the electronics/semiconductor field and global expansion based on the Medium-Term Management Plan 2030
Risks
- Decline in automobile production volumes and sluggish demand for automotive tools due to the impact of U.S. trade policy
- Impact on business in Asia due to the stagnation of the Chinese economy and rare earth issues
- Stagnant demand for power semiconductor-related tools due to a global slowdown in EV sales
- Continued sluggish demand in the domestic and overseas stone/construction industries
- Risk of additional costs arising from business structure improvements at the European subsidiary
- Risk of impairment loss on fixed assets (an impairment loss of ¥1,920 million was recorded in the fiscal year under review)
