Dear Sir:

Pursuant to the provisions of article 9 and paragraph two of article 10, of Securities Market Law No. 18,045, and to the established provisions of General Norm No. 30 of that Superintendence, duly empowered on behalf of Endesa Américas S.A.

Under the United States rules applicable to the case, the information statement/prospectus that is part of the Form F-4 will be made available to shareholders and holders of ADSs to inform them about matters to be voted on at the upcoming extraordinary shareholders’ meetings of Enersis Américas S.A. and Endesa Américas to be held on September 28, 2016, and about the shares and ADSs of Enersis Américas S.A. that will be offered in exchange to holders of Endesa Américas shares and ADSs in the merger.
