Financial Results

Sales Revenue

2,895.3 Billion Yen

Although shipments declined due to the global economic slowdown, product market prices increased, primarily in petrochemicals, cathode materials, and crop protection chemicals. In addition, the weaker yen in exchange rates in each business resulted in an increase in sales revenue of 130.0 billion yen compared to the previous year.

Overseas Sales Revenue Ratio


Revenue from sales outside of Japan exceeded 60% of the total, mainly due to a significant amount of sales in the Pharmaceuticals sector in North America, as well as in petrochemicals and the IT-related Chemicals sector in China.

Core Operating Income

92.8 Billion Yen

Sales of crop protection chemicals remained steady. On the other hand, petrochemicals were affected by a deterioration in the terms of trade due to higher raw material prices and a decrease in shipments. Shipments of display-related materials decreased due to a decline in the previous strong demand from stay-at-home measures. In addition, in pharmaceuticals, there was a decrease in sales of Latuda, as well as an increase in sales and general administrative expenses, and the effects of price revisions in Japan. These factors resulted in a decline in core operating income of 142.0 billion yen compared to the previous year.
