[ Reasons for the revision ]Difference between Performance Forecast and Results
Net sales were lower than expected due to a decrease in the volume of graphite electrodes in theChemicals segment, while demand for semiconductor materials and HD media remained strong in
the Semiconductors and Electronic Materials segment. Operating income significantly exceeded
expectations due to the sales increase in the Semiconductors and Electronic Materials segment.
Ordinary income significantly exceeded expectations due to an increase in operating income and animprovement in non-operating income. Net income attributable to owners of the parent significantly
exceeded expectations due to an increase in ordinary income and an improvement in extraordinary
income.
Revised Forecast of Consolidated Performance
Based on the results of the first half of the fiscal year, and due to continued strong demand in theSemiconductor and Electronic Materials segment, we expect both sales and operating income toincrease. As a result, we have revised upward the forecasts for sales, operating income, ordinary
income, and net income attributable to owners of parent. The assumptions for foreign exchange rates
and domestic naphtha pricing have been also revised.
