Enersis Américas S.A. (“Enersis Américas”, “we”, “us” and “our”) is filing this Report on Form 6-K to provide an update on the pending concurrent tender offers for (i) all outstanding shares of common stock of Endesa Américas S.A. (“Endesa Américas”), other than shares owned by Enersis Américas, for Ch$ 300 per share (the “Chilean Offer”) and (ii) all outstanding shares held by holders of Endesa Américas shares resident in the United States (“U.S. Holders”) for Ch$ 300 per share, payable in U.S. dollars, and all outstanding American Depositary Shares (ADSs) from all holders of Endesa Américas ADSs for Ch$ 9,000 per Endesa Américas ADS, payable in U.S. dollars (the “U.S. Offer”), and exercises of statutory merger dissenters’ withdrawal rights in connection with the pending merger of Endesa Américas and Chilectra Américas S.A. (“Chilectra Américas”) with and into Enersis Américas (the “Merger”).

As of the close of business on October 20, 2016, there were 287,266 Endesa Américas shares validly tendered in the Chilean Offer and 775 Endesa Américas shares or Endesa Américas ADSs validly tendered in the U.S. Offer. The Chilean Offer and the U.S. Offer (collectively, the “Offers”) were commenced on September 14, 2016 and are currently expected to expire at 5:30 p.m. Chilean time (4:30 p.m. New York City time) on October 28, 2016. On October 20, 2016, the closing price for Endesa Américas shares on the Santiago Stock Exchange was Ch$ 322.89 per share.

Among the conditions to the completion of the Offers and the Merger is that less than 10% of the outstanding shares of Enersis Américas, 10% of the outstanding shares of Endesa Américas and 0.91% of the outstanding shares of Chilectra Américas exercise the statutory merger dissenters’ withdrawal rights provided under Chilean law, provided that no shareholder of will own more than 65% of Enersis Américas on the day of the expiration of the period to exercise statutory merger dissenters’ withdrawal rights by dissenting shareholders, considering the number of shares in the new share capital of Enersis Américas approved by shareholders in connection with the Merger on September 28, 2016.

As of the close of business on October 20, 2016, there were exercises of statutory merger dissenters’ withdrawal rights with respect to the following number of shares: (i) 1,891,558 Enersis Américas shares, representing less than 0.01% of the outstanding shares; (ii) 982,519 Endesa Américas shares, representing 0.01% of the outstanding shares; and (iii) 17,904 Chilectra Américas shares, representing less than 0.01% of the outstanding shares. The exercise period for the statutory merger dissenters’ withdrawal rights expires on October 28, 2016, the same day as the expiration of the Offers.

There can be no assurance as to whether or when the conditions to the Offers or the Merger will be satisfied. Under Chilean law, the Merger will become effective as of the first day of the calendar month following the month in which a deed of compliance with the merger conditions is granted. Although Enersis Américas initially expected to complete the Merger on or before December 1, 2016, Enersis Américas is currently evaluating a possible Merger effective date of January 1, 2017 in order to provide additional time for regulatory compliance in connection with the Merger, the issuance of the Enersis Américas shares and ADSs to be exchanged for Endesa Américas shares and ADSs and Chilectra Américas shares, as applicable, in the Merger, and listing of such shares and ADSs with Chilean stock exchanges and the New York Stock Exchange, respectively.

The information in this Report on Form 6-K shall be incorporated by reference into the registration statement on Form F-4 of the Company (Registration No. 333-211405).
