Recent Overview
Sales increased but profit declined due to higher cost ratio, as semiconductor and automotive demand remained weak
Full-year sales for FY2026 (ending March 2026) reached ¥12,439 million (up 3.7% year on year), securing an increase in revenue, but operating income declined to ¥1,963 million (down 5.0% year on year). While demand from the semiconductor and automotive-related industries remained weak, demand from the industrial machinery sector remained firm. On the profit side, the cost ratio rose due to increased expenses and higher procurement costs stemming from the strong Thai baht, causing the operating margin to fall from 17.2% to 15.8%.
Key Products
Growth Drivers
- Recovery and increase in demand for semiconductor manufacturing equipment amid the spread of generative AI
