(“EDP”), hereby notifies the acquisition of 70,143,242 shares representing around 1.9183% of EDP’s share capital (“Shares”).

The acquisition of the Shares results from an off-market transaction of 2017/09/29, only subject to the applicable physical and financial settlement mechanisms.

As CTG Europe is a subsidiary fully held by China Three Gorges Corporation (“CTG”), a state-owned company from the People’s Republic of China, all voting rights inherent to said 850,777,024 shares, are attributable to CTG.”
