Note:

The content of statements concerning financial forecasts are based on certain assumptions judged to be reasonable at the present time in light of information currently available concerning economic conditions in Japan and overseas, fluctuations in exchange rates and other factors that may have an impact on performance.

They are therefore susceptible to the impact of many uncertainties, including market conditions, competition, the launching of new products and their success or failure, and global conditions in the semiconductor production equipment business. Consequently, actual sales and profits may differ substantially from the projected figures.

[Reason for revision]

Net sales in the semiconductor production equipment division are likely to exceed previous forecasts as a result higher orders.
