FY11/26 Forecast Medium-Term Management Plan Progress Appendix

Operating environment

The economy is on a gradual recovery trajectory, buoyed by improvements in the employment and income environment and by the effects of various government policies. However, the outlook remains uncertain with risks of a downturn in the economy stemming from factors such as the impact of U.S. trade policy and rising prices in Japan.



Net sales

Net sales increased compared to the previous year in each business of Chemical Products, Electronic Materials and Specialty

Chemicals. As a result, net sales for the fiscal year under review increased 10.9% year on year to 36,265 million yen.

Operating profit

Operating profit increased by 34.2% year on year to 6,187 million yen due to factors such as a decrease in depreciation, in addition

Summary

  • Sales of products for automotive coatings are on a recovery track.

  • Sales of products for display adhesives and UV inkjet inks performed robustly.

  • Sales of methacrylate were sluggish.

  • The semiconductor materials group saw a drop in sales of cutting-edge raw materials for EUV resists, but sales of mainstay raw materials for ArF resists recovered and drove a sizeable increase in the group-wide sales.

  • The display materials group's sales as a whole

were flat, despite the strong performance of insulating films for touch panels.

  • The cosmetics materials group's sales remained flat.

  • The functional materials group recorded strong sales.

  • Sales of high-purity specialty solvents produced by a subsidiary remained solid.

FY11/26 Forecast

In the fiscal year ending November 30, 2026, we forecast net sales of 37.5 billion yen, an increase of 1.2 billion yen, based on expectations of a continued recovery trend in the semiconductor market and steady performance in the market of chemical products and specialty chemicals. Operating profit is expected to increase by 0.2 billion yen to 6.4 billion yen, primarily due to decreased depreciation.

(*The decrease in profit is mainly due to the recording of 3.1 billion yen in subsidy income as extraordinary income in the previous period.)
