Revision of Earnings Forecasts

Tokyo, Japan(July 31, 2009) – Daiichi Sankyo Company Limited today announced a revision of its earnings forecasts which was announced on May 12, 2009 , in light of recent trends in operating performance.

Revisions to Consolidated Earnings Forecasts for the First Six Months of Fiscal Year Ending March 2010


Main reasons for revising earnings forecasts
With regard to the earnings forecasts for the first six months of the fiscal year ending March 2010 (from April 1, 2009 to September 30, 2009), operating results at the end of the three months ended June 30, 2009 were generally firm and net sales and operating income for the six months are expected to be as previously forecasted.

With respect to non-operating revenues, the disarray on the foreign exchange market is winding down and foreign exchange losses/gains related to Ranbaxy Laboratories Limited, our consolidated subsidiary, have become more favorable. As a result, ordinary income has been upwardly revised.

Net income, on the other hand, has been upwardly revised by a smaller amount as a result of cases of non-application for R&D tax credit, income tax amendments related to prior periods and others.

Based on the above circumstances, the Company has amended the earnings forecasts of the first six months of the fiscal year ending March 2010 announced on May 12, 2009 as follows. With respect to net sales and operating income, no changes have been made. Ordinary income, however, has been upwardly revised to ¥37.0 billion, up ¥20.0 billion, and net income has been upwardly revised to ¥11.0 billion, up ¥3.0 billion.

The earnings forecasts for the full fiscal year remain unchanged from the previously announced forecasts.


 The forecasted statement shown in these materials 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.
