Reason for the difference
We had expected demand to remain steady, particularly in the semiconductor industry, one of our major
customers. However, in response to the global shortage of semiconductor components and the trend of
aggressive investment in electric vehicles, capital investment by the semiconductor industry in East Asia
(mainly China and Taiwan) and by the lithium-ion battery industry in China were brisk beyond our initialexpectations. In addition to this, the effects of the weak yen and other factors contributed to higher-thanexpected net sales, operating profit, ordinary profit, and net profit attributable to owners of parent (netprofit) on a consolidated and non-consolidated basis.

Reason for the revision
Financial results for the fiscal year ending March 31, 2023, are expected to exceed the previous forecast, as
capital investment in the semiconductor industry, one of our major customers, is expected to remain steadyfollowing on from the first six months of the current fiscal year. On the other hand, we should pay close
attention to the impact of the supply shortage of semiconductor and electronic components in the future.
Taking these factors into consideration, we revised financial results forecast as described above.

The above forecasts have been prepared based on information currently available to the Company, andactual financial results may differ from the forecasts due to various factors.
