2. Reason for difference and revision
The consolidated financial forecasts for the fiscal year ending March 31,2023 announced on May 2, 2022
were based on the assumptions that the global economy was recovering from COVOD-19, but that raw
material prices are increasing and remaining at high levels in Japan and overseas and these would have animpact on our business performance.
With regard to the consolidated financial results for the six months ended September 30, 2022, profit at eachstage exceeded initial forecasts due to the effects of the progress in passing on the increase in raw material
prices to product prices, depreciation of the yen and other factors.
With regard to the consolidated financial forecasts for the fiscal year ending March 31,2023, although thepace of economic recovery is expected to decelerate due to the impact of monetary tightening overseas andother factors, profit at each stage is expected to exceed the initial forecast, reflecting the actual results of thefirst half.
