Tokyo, Japan, October 29, 2010 - "The company raised its recurring profit forecast to 100 billion yen from 85 billion yen for the year to March 2011."

In the six months ended September 30, 2010, operating income rose due to efforts to curtail overall expenses, mostly R&D expenses being carried forward into the third quarter or later, and other factors. Also, ordinary income and net income rose significantly above the forecasts. For the fiscal year ending March 31, 2011, while on one hand we fear a decrease in sales due to the long-term trend of the strong yen, mainstay product sales are expected to expand, offsetting any decrease. Therefore, the initial forecast for net sales is unchanged. Daiichi Sankyo is upwardly revising profits in order to push forth the curtailment of overall expenses.

The above forecasts are based on information currently available and certain assumptions that the Company regards as reasonable. Actual performance and other results may differ materially from these forecasted figures due to various factors.
