COMMUNICATION

In accordance with and for the purposes of article 17 of the Regulation (EU) No 596/2014, of the European Parliament and of the Council, of 16 April 2014, of article 248A of the Portuguese Securities Code and other applicable regulations, REN – Redes Energéticas Nacionais, SGPS, S.A. hereby informs the market and the public that, following the communication to the market and the public of 23rd July 2019, its subsidiaries Aerio Chile SpA and Apolo Chile, SpA, acquired today the entire share capital of Empresa de Transmisión Eléctrica Transemel S.A. ("Transemel") from Compañia General de Electricidad S.A. and Naturgy Inversiones Internacionales, S.A., for 168.6 million USD.

Transemel, with approximately 93% of its revenues coming from regulated activities, owns and operates 92 km of electricity transmission lines and 5 substations, located mainly in northern Chile.

As previously disclosed, this transaction was financed solely with debt.

This is the second acquisition that REN makes in Chile and is in line with REN's strategic plan, which is based on a conservative growth strategy, favoring projects in the sectors in which the Company has a vast experience, and in markets with economic stability and predictable regulatory frameworks.

Despite remaining attentive to investment opportunities abroad, Portugal is REN's main target and natural market, where it will continue to invest to ensure the long-term needs of the electricity and natural gas infrastructures, with a permanent focus on improving performance and quality of service, to provide a reliable, safe and efficient service at the lowest possible cost to the country and to the consumers.
