Daiichi Sankyo to Transfer all Daiichi Fine Chemical Shares to Kyowa Hakko

Tokyo, April 23, 2007-DAIICHI SANKYO COMPANY,LIMITED and Kyowa Hakko Kogyo Co., Ltd.(President Yuzuru Matsuda) have agreed to transfer to Kyowa Hakko all shares of Daiichi Fine Chemical Co., Ltd.(President:Syunya Tamai).

Daiichi Fine Chemical manufactures, imports, and sells pharmaceuticals,veterinary medicines, IVD (in vitro diagnostic) reagents, and chemical intermediates.The company's earnings are growing steadily.

Kyowa Hakko intends to further grow its business by taking over the entire Daiichi Sankyo shareholding in Daiichi Fine Chemical and making Daiichi Fine Chemical a wholly owned subsidiary.The Kyowa Hakko group expects the move to allow it to supply first-class pharmaceutical and chemical intermediates and other products globally through the organic integration of Daiichi Fine Chemical'sorganic synthesis technologies and Kyowa Hakko's fermentation technologies.The Group will enhance its sales capabilities by having Kyowa Hakko and Daiichi Fine Chemical leverage one another's sales networks and develop the group's Bio-chemicals business by positioning Daiichi Fine Chemical at its core.

If Daiichi Sankyo's business performance of the fiscal year ended March 2008 is changed due to this share transfer, we will disclose it at a later date.
