As a result of Law Decree 205 - G/75 (April 16th), which led to the nationalisation of companies operating in electricity generation, transmission and distribution at the time, EDP was created in accordance with the provisions of Law decree 502/76 (June 30th), with the merger of the aforementioned companies’ assets and the attribution of the exclusive rights for Portugal’s mainland public service of electricity generation, transmission and distribution.
EDP, initially 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, EDP is listed on the Euronext Lisbon and the Portuguese State holds no share on EDP, either directly or indirectly.
EDP’s shares were initially listed on the Euronext Lisbon’s official securities market (known then as the Lisbon Stock Exchange) on 16 June 1997. The Company later underwent 8 additional privatisation phases from 1997 to 2011.
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.
