An ADS (American Depositary Shares) is a receipt that is issued by a depositary bank representing ownership of the Company's underlying ordinary shares. Each ADS represents ten ordinary shares.

On May 18, 2007 the Executive Board of Directors of EDP - Energias de Portugal, S.A. adopted a resolution that approved the delisting of its American Depositary Shares, from the New York Stock Exchange ("NYSE") and the deregistration of the Company and termination of its reporting obligations under the U.S.

Following the delisting from the NYSE, the Company's common shares will continue to trade on Euronext and EDP will continue to publish its Annual Report and Accounts and other documents and communications in accordance with Exchange Act Rule 12g3-2(b) on its Investor Relations website.

EDP maintains its ADS facility with Deutsche Bank as a Level I Program which will enable investors to retain their ADSs while facilitating EDP ADS trading in the US over-the-counter market.

The Company ADS Program is sponsored by Deutsche Bank Trust Company Americas.
