Between 1997 and 2001 EDP has passed by 8 different privatisation phases
As a result of Decreto-Lei nº 205 - G/75, de 16 de Abril, that led to the nationalisation of companies which were operating in electricity generation, transmission and distribution at the time, EDP was created in accordance with the provisions of Decreto-Lei nº 502/76, de 30 de Junho, with the merger of the aforementioned companies' assets and the attribution of the exclusive rights for Portugal’s mainland public service of electricity generation, transmition and distribution.
EDP, which began as a State-owned company, saw its statute successively transformed from a Public Limited Company of exclusively public capital to a Public Limited Company of mainly public capital. Currently it is a Public Limited Company in which the Portuguese State and other Public Entities have a minority shareholding.
EDP’s shares were initially listed on the Euronext Lisbon’s official securities market (known then as the Lisbon Stock Exchange) on 16 July 1997. The Company later underwent additional privatisation phases in 1998, 2000, 2004 and 2005.
On 17 July 2000 a 1-to-5 Stock-split took place as a result of an amendment to the nominal value of the shares representing EDP share capital, from EUR 5 to EUR 1.
In November 2004 EDP went ahead with a capital increase through the public offering of shares, reserved to shareholders, of 656,537,715 new shares with a nominal value nominal of EUR 1 each, at a unit price of EUR 1.84.
