• Semi-annual financial results reports are exempt from review conducted by certified public accountants or an audit firm.
• Proper use of earnings forecasts, and other special matters

(We urge you to be cautious in relying on forward-looking statements.)

Forward-looking statements such as the earnings forecasts in this material are based on currently available information and certain assumptions deemed rational, and are not intended as a guarantee that these forecasts will be achieved. Accordingly, actual results may differ significantly from these forecasts due to various factors.

In the third quarter onward, the Company originally anticipated a recovery in the Si (silicon) semiconductor market, but it now appears that this recovery will take some time, while the current adjustment in the SiC (silicon-carbide) semiconductor market is expected to continue. In this market environment, demand for the Company's products for semiconductor applications is forecast to decline. Demand for products for metallurgical applications is also forecast to decline, mainly due to the impact of postponement of capital investment. As a result of these factors as well as a decrease in marginal profit, both net sales and profit are forecast to fall short of the initial targets.

Faced with this situation, the Company will respond robustly to changes in the market by focusing on pioneering new applications and further developing existing applications to control the balance of applications, as well as by curbing personnel expenses and other fixed costs.

Based on these conditions and its results for the six months ended June 30, 2025, the Company has revised its consolidated earnings forecast for the year ending December 31, 2025.
