Astellas Completes Acquisition of Ogeda SA

TOKYO, May 16, 2017

Under the share purchase agreement executed between Astellas and Ogeda shareholders, Astellas paid EUR 500 million to acquire 100% of the equity in Ogeda. In addition, Ogeda shareholders will become eligible to receive up to EUR 300 million in further contingent payments based on progress in the development of fezolinetant, Ogeda's most advanced clinical program for the treatment of menopausal-related vasomotor symptoms.

This transaction expands Astellas' late stage pipeline and is expected to contribute to its mid-to-long term growth.

Astellas reflected the impact from this closing of transaction in its financial forecasts of the current fiscal year ending March 31, 2018
