OFFERING OF NEW AMERICAN DEPOSITARY SHARES OF ENEL AMÉRICAS S.A. AT A PRICE OF US$8.31 PER AMERICAN DEPOSITARY SHARE

PREEMPTIVE ADS RIGHTS CERTIFICATE

In connection with the offers (the “Preemptive Rights Offers”) by Enel Américas S.A. (“Enel Américas”) to holders of shares of its common stock (the “Shares”) of rights to subscribe for new Shares (the “Preemptive Share Rights”), Enel Américas is offering to holders of its American Depositary Shares (the “ADSs”) registered as such at 5:00 p.m. (New York City time) on July 2, 2019 (the “ADS Record Date”) rights to subscribe for new ADSs (the “Preemptive ADS Rights”).  The Preemptive ADS Rights may be exercised at any time during the period beginning July 3, 2019 and ending at 2:15 p.m. (New York City time) on July 23, 2019 (the “Preemptive ADS Rights Subscription Period”).

For each ADS held as of the ADS Record Date, a holder of ADSs will receive approximately 0.326003 Preemptive ADS Rights.  Holders will receive only a whole number of Preemptive ADS Rights.  Fractional entitlements to Preemptive ADS Rights will be aggregated and sold by Citibank, N.A. (“Citibank”), as ADS Rights Agent (the “ADS Rights Agent”), and net sales proceeds after deduction of all applicable fees, taxes and expenses will be distributed to the applicable holders of ADSs as of the ADS Record Date.  One (1) Preemptive ADS Right entitles the holder of ADSs to purchase one (1) new ADS at a subscription price of US$8.31 per subscribed new ADS (the “ADS Subscription Price”).  To subscribe for new ADSs, the holder of Preemptive ADS Rights must indicate on the certificate representing Preemptive ADS Rights (the “Preemptive ADS Rights Certificate”) the number of new ADSs for which such holder desires to exercise Preemptive ADS Rights.  The CUSIP No. for Enel Américas’ ADSs is 29274F104, which are quoted on The New York Stock Exchange under the symbol “ENIA”.  The CUSIP No. for the Preemptive ADS Rights is 29274F138 which will be quoted on The New York Stock Exchange under the symbol “ENIA RT”.

To exercise Preemptive ADS Rights and to subscribe for any new ADSs, holders of Preemptive ADSs Rights must pay the ADS subscription price of US$8.31 per subscribed new ADS, which includes the fees incurred in connection with the ADS rights and the issuance of the new ADSs of US$0.20 per new ADS. The exercise of Preemptive ADS Rights is irrevocable and may not be cancelled or modified.

Upon expiration of the Preemptive Rights Offers and to the extent that there are any new Shares remaining unsubscribed after the Preemptive Rights Offers (subject to reduction to the extent necessary not to exceed the US$3.0 billion limit of the capital increase authorized by shareholders) (the “Unsubscribed Shares”), each holder of Preemptive ADS Rights who exercised his/her Preemptive ADS Rights shall receive a distribution of a number of transferable ADS Rights (the “Additional ADS Rights”) to purchase new ADSs representing a proportionate share of the Unsubscribed Shares, based on the number of new shares underlying the new ADSs subscribed and paid for in the Preemptive Rights Offers, with each full Additional ADS Right entitling the holder thereof to purchase one (1) new ADS subject to the same price, and certain terms and conditions as those Preemptive ADS Rights subscribed and paid for in the Preemptive Rights Offers and as further described in the Prospectus. A separate set of documentation (other than the Prospectus) will be distributed in connection with the Additional ADS Rights.

Each subscriber should read the Prospectus, dated June 18, 2019, together with the accompanying Prospectus Supplement, dated June 27, 2019 (collectively, the “Prospectus”) provided with this Preemptive ADS Rights Certificate for a complete description of the offering of new ADSs.  Terms not defined herein shall have the meaning given to them in the Prospectus.  The undersigned holder of existing ADSs issued under the Third Amended and Restated Deposit Agreement, dated as of March 28, 2013, by and among Enel Américas, Citibank, in its capacity as depositary, and all Holders and Beneficial Owners of ADSs issued thereunder, hereby provides to ADS Rights Agent the following instructions in connection with the offering of new ADSs.

If you do not indicate below the number of new ADSs subscribed for or if you indicate a number of new ADSs which does not correspond to the total U.S. dollar amount delivered to ADS Rights Agent, you will be deemed to have subscribed for the maximum number of new ADSs that may be purchased with the amount delivered to ADS Rights Agent.
