PRESS RELEASE CONSOLIDATED FINANCIAL STATEMENTS ENEL AMÉRICAS GROUP AS OF SEPTEMBER 30, 2026 Page 1 EXECUTIVE SUMMARY CONSOLIDATED FINANCIAL STATEMENTS ENEL AMÉRICAS GROUP AS OF SEPTEMBER 30, 2026 (figures expressed in millions of US$) • In the third quarter of 2026, revenues reached US$4,614 million, representing an increase of 26.3% compared to the same period of the previous year. This is mainly explained by an increase in revenues in Argentina, Brazil and Colombia, due to higher tariff indexation, higher energy distributed, higher energy sales in Colombia and the positive effect of the appreciation of the Brazilian real and the Colombian peso. • On a cumulative basis through September, revenues reached US$12,766 million, representing an increase of 22.3% compared to 2025, explained by higher revenues in Argentina, Brazil and Colombia, partially offset by lower revenues in Central America due to lower energy sales. • EBITDA in the third quarter of the year reached US$1,417 million, representing an increase of 37.7% compared to the same period of the previous year. This is mainly explained by better results in Argentina and Brazil, due to tariff adjustments, and in Colombia, due to higher energy sales at higher prices and higher tariff indexation. This is partially offset by a lower result in Central America, due to lower hydroelectric generation and higher energy purchases during the period. Excluding the positive impact of US$179 million from the exchange rate, EBITDA would have grown 20% compared to the same period of the previous year. • On a cumulative basis, EBITDA reached US$3,845 million, 23.8% higher than in the same period of the prior year. This is explained by an increase in the results of Argentina, Brazil and Colombia, partially offset by a lower result in Central America. Excluding the positive impact of US$420 million from the exchange rate, EBITDA would have grown 10% compared to the same period of the previous year.

On a cumulative basis, EBIT increased 39.0% to US$2,711 million. • Net Income attributable to Enel Américas shareholders reached US$390 million in the third quarter of 2026, showing an increase of 86.4% compared to the US$209 million recorded in the third quarter of 2025. This is mainly explained by better results in Argentina, Brazil and Colombia, partially offset by a lower result in Central America. On a cumulative basis, Net Income reached US$902 million, equivalent to an increase of 40.6% explained by better results in Brazil and Colombia. • Net financial debt reached US$6,508 million, representing an increase of 35.3% compared to year -end 2025, mainly explained by higher debt at Edesur and at the subsidiaries in Brazil, and lower cash at Enel Américas Holding due to the payment of the dividend charged to 2025 earnings and the execution of the share buyback program. • CAPEX in the third quarter of 2026 amounted to US$650 million, representing an increase of 20.0% compared to the third quarter of 2025, explained by higher investments in the distribution business in Argentina, Brazil and Colombia, partially offset by lowe r investments in generation in Brazil and Colombia. CAPEX through September 2026 reached US$1,633 million, resulting in an increase of 9.8% compared to the same period of the previous year, mainly due to higher investments in distribution in the countries within our perimeter.

Rounding The figures in this report are expressed in millions of U.S. dollars and, to facilitate their presentation, have been rounded. For this reason, the sum of the figures contained in the tables may not exactly equal the total shown in the table. SUMMARY BY BUSINESS Generation and transmission in continuing operations In the third quarter of 2026, EBITDA in the generation and transmission business increased by 58.4% compared to the same quarter of 2025, reaching US$710 million. This is mainly explained by higher generation in Colombia and the appreciation of the Brazilian real and the Colombian peso against the U.S. dollar, partially offset by lower generation in Brazil and Central America and i n Argentina, due to the non-renewal of the concession of the generation assets operated by Enel Generación El Chocón1. Considering cumulative EBITDA as of September 30, 2026, the generation and transmission business reached US$1,643 million, 32.3% higher than in the same period of 2025, also explained by the higher result in Colombia, offset by a lower result in Argentina and Central America. Physical energy sales from continuing operations decreased by 12.4% in the third quarter , mainly explained by lower sales in Argentina, Brazil and Central America, related to the non -renewal of the concession of the generation assets operated by Enel Generación El Chocón, lower trading activity in Brazil and lower own renewable generation, respectively, partially offset by higher sales in Colombia due to higher own generation. As of September 30, 2026, energy sales decreased by 12.0%, also mainly due to lower sales in Argentina, Brazil and Central America. In turn, energy generation in the third quarter decreased by 0.6% compared to the same period of 2025, mainly explained by lower generation in Argentina, due to the non -renewal of the concession of the generation assets operated by Enel Generación El Chocón, and lower renewable generation in Brazil and Central America, partially offset by higher generation in Colombia. Regarding the cumulative figure as of September 30, 2026, energy generation decrease d by 4.4% compared to 2025, due to lower generation in Argentina, Brazil and Central America.

This is mainly explained by a better result in Argentina, Brazil and Colombia due to higher tariff indexation. On a cumulative basis, EBITDA as of September 30, 2026, increased by 17.9%, reaching US$2,251 million, also explained by a better result in all the countries within our perimeter. As of September 30, 2026, the consolidated number of customers in continuing operations showed an increase of 349 thousand, or 1.5%, compared to the same period of 2025, reaching 23.2 million. In turn, physical sales increased by 2.8% in the quarter, explained by higher sales in Brazil and Colombia, partially offset by lower sales in Edesur in Argentina. On a cumulative basis, during the 2026 period sales increased by 1.4% compared to 2025, mainly driven by increases across all our concessions.

PRESS RELEASE CONSOLIDATED FINANCIAL STATEMENTS ENEL AMÉRICAS GROUP AS OF SEPTEMBER 30, 2026 Page 7 EBITDA The EBITDA for continuing operations for the period ended on September 30, 2026 amounted to US$3,845 million, representing an increase of US$740 million, equivalent to 23.8% compared to the US$3,106 million of the same period of 2025. This increase is mainly explained by better results in the distribution business in Brazil and Colombia, related to higher tariff indexation, higher energy distributed and the appreciation of the Brazilian real and the Colombian peso against the U.S. dollar. The increase in EBITDA during the third quarter of 2026 amounted to US$388 million, which is mainly explained by better results in Colombia, related to higher generation, and Brazil in distribution and transmission.

The main variables that explain the items that make up EBITDA are explained below: The operating revenues increased by US$198 million, equivalent to 20.5%, compared to the 2025 period. The increase is mainly explained by; (i) US$120 million of positive effect from translation of figures due to the appreciation of the Brazilian real against the U.S. dollar; and (ii) US$69 million from higher average selling prices. The operating costs increased by US$183 million, or 40.6%, compared to the 2025 period. The increase is mainly explained by; (i) US$108 million of higher energy purchase costs, mainly due to higher volume; and (ii) US$73 million of negative effect from translation of figures due to the appreciation of the Brazilian real against the U.S. dollar. The personnel expenses remained practically in line with those recorded in the 2025 period. The other expenses by nature increased by US$17 million mainly due to negative effect from translation of figures due to the appreciation of the Brazilian real against the U.S. dollar. Regarding EBITDA for the third quarter of 2026, it reached US$144 million, which implies a decrease of US$13 million compared to that reached in the same period of 2025. The main variables involved are explained by US$71 million of lower revenues in energy volumes (-2.1 TWh) and lower average selling prices. The aforementioned was partially offset by; (i) US$46 million from lower purchase volumes; and (ii) US$7 million of positive effect from translation of figures due to the devaluation of the Brazilian real against the U.S. dollar.

The main variables that explain this increase in the items that make up EBITDA are explained below: The operating revenues of Enel Colombia Generación increased by US$564 million in the period ended September 30, 2026, or 46.2% compared to the revenues recognized in the 2025 period. This increase is mainly explained by; (i) US$301 million from higher physical sales of electricity (+0.7 TWh) ; and (ii) positive effect of US$273 million from translation of figures, related to the appreciation of the Colombian peso against the U.S. dollar. The foregoing was partially offset by US$7 million from lower indemnities for claims. The operating costs increased by US$98 million, equivalent to 19.3%, and is mainly explained by; (i) negative effect from translation of figures of US$92 million due to the appreciation of the Colombian peso against the U.S. dollar; (ii) US$ 15 million of higher cost from fuel-based generation; and (iii) US$14 million due to an increase in the volumes of energy purchased. The foregoing was partially offset by US$23 million of lower transportation cost. The personnel expenses increased by US$13 million mainly due to higher salary costs from adjustments. The other expenses by nature increased by US$14 million basically due to higher costs resulting from the entry into force of the wealth tax in the 2026 period. Regarding the third quarter of 2026, the EBITDA of our generation segment in Colombia reached US$527 million, exceeding by US$300 million the figure reached in the same quarter of the 2025 period. This increase is mainly explained by: (i) US$278 million of higher revenues from physical volume and higher average selling prices in the spot market; (ii) US$44 million of lower transportation costs, and (iii) US$42 million from the positive effect of translation of figures due to the appreciation of the Colombian peso against the U.S. dollar. All of the foregoing was partially offset by; (i) US$50 million from higher energy purchases to cover demand due to higher generation compared to the same quarter of the 2025 period; and (ii) US$13 million of higher cost of fuel-based generation.

The operating costs increased by US$280 million, or 31.4%, which are mainly explained by; (i) US$179 million of negative effect from translation of figures originating from the appreciation of the Colombian peso against the U.S. dollar, and (ii) US$100 million of higher costs due to the increase in average energy purchase prices. The personnel expenses remained in line with those recorded in the same 2025 period. The other expenses by nature increased by US$6 million, mainly due to; (i) US$19 million from the negative effect of translation of figures due to the appreciation of the Colombian peso against the U.S. dollar, and (ii) US$6 million from higher maintenance costs for operations. The foregoing was partially offset by US$22 million of lower operating expenses related to third-party service costs. costs of purchasing materials and supplies for the operation. Regarding the third quarter of 2026, the EBITDA of our distribution segment in Colombia reached US$244 million, higher by US$34 million than the figure reached in the same period of 2025. This increase is mainly explained by; (i) US$80 million of higher physical sales volumes; and (ii) US$39 million of positive effect from translation of figures, due to the appreciation of the Colombian peso against the U.S. dollar in the third quarter of 2025. The foregoing was partially offset by US$84 million due to an increase in costs in energy purchase prices. Energy losses (%) Number of Customers (in millions) Sep-26 Sep-25 Var p.p.

This decrease is mainly explained by; (i) US$ 1 45 million from lower recognition of impairment losses on financial assets, comprised of: (a) a decrease of US$108 million, mainly explained by the update of parameters and assumptions associated with trade receivables of the distribution companies in Brazil, Enel Distribución Sao Paulo , Enel Distribución Rio and Enel Ceará, mainly those related to loss given default (LGD). The update incorporated more recent historical information on the recovery behavior of the portfolios and the recovery expectations for them; (b) US$36 million from lower losses from recognition of impairment of financial assets at Enel X Brasil due to a better recovery outlook for its receivables ; offset with (c) increases of US$36 million from the application of IFRS 9 due to a deterioration in the determination of expected credit loss mainly at the companies Edesur, and Enel Colombia. The foregoing was partially offset with US$14 million of higher impairment losses on long- lived generation assets at Enel Colombia associated with an adjustment to the impairment of the Windpeshi renewable project plant in 2025. In the third quarter of 2026, depreciation, amortization and impairment of continuing operations amounted to US$331 million, decreasing by US$59 million compared to the close of the same period of 2025. The depreciation and amortization amounted to US$331 million in the third quarter ended September 30, 2026, an amount that is US$15 million higher than that recorded in the same period of 2025; mainly due to US$15 million of higher depreciation due to the commencement of operation of new renewable source generation projects in Brazil and Colombia. In turn, the impairment losses in the third quarter of 2026,recorded a decrease of US$74 million compared to the same period of 2025. This variation is mainly explained by a decrease of US$82 million in impairment losses on financial assets, highlighting; US$107 million of lower impairment losses on Brazilian financial assets at Enel Distribución Sao Paulo, Enel Distribución Rio and Enel Ceará due to better recovery prospects for their receivables; partially offset with US$25 million of higher loss at Enel Colombia, and Edesur due to a deterioration in the determination of expected credit loss, in accordance with the guidelines of IFRS 9.

PRESS RELEASE CONSOLIDATED FINANCIAL STATEMENTS ENEL AMÉRICAS GROUP AS OF SEPTEMBER 30, 2026 Page 19 Financial Result The financial result amounted to a loss of US$700 million in the period ended September 30, 2026, representing a greater loss of US$126 million compared to that recorded during the 2025 period. The detail of its composition is presented below. (a) Higher financial income of US$82 million, mainly explained by; (i) US$105 million from higher update of regulatory assets and liabilities in Brazil, due to the higher inflation recorded in that country compared to 2025; and (ii) US$5 million of higher financial income from higher interest collections from customers. The foregoing was partially offset by (i) US$20 million of lower updates of taxes of Brazilian companies; (ii) US$9 million of lower income from derivative transactions in the distribution companies in Brazil; and (iii) US$5 million from lower income from updates of leases and accounts receivable. In the third quarter of 2026, financial income increased by US$25 million compared to the previous period. This is mainly explained by; (i) US$46 million of higher update of regulatory assets and liabilities in Brazil, due to the higher inflation recorded in that country in the third quarter compared to the previous period; (ii) US$15 million of higher income from updates of leases and accounts receivable; and (iii) US$9 million of higher income from updates of cash and cash equivalents accounts mainly in Brazil and Colombia. The foregoing was partially offset by; (i) US$21 million of lower income from derivative transactions in the distribution companies in Brazil; (ii) US$21 million of lower updates of taxes of Brazilian companies. (b) Higher financial expenses of US$249 million mainly explained by; (i) US$205 million of higher financial expenses on bank loans, originating mainly from the increase in debt at Enel Colombia and in Brazil; (ii) US$81 million from higher expense in updates of regulatory assets and liabilities in Brazil (iii) US$15 million of higher expense incurred on obligations with the public for the bonds that the company holds in Brazil; (iv) US$11 million from higher interest associated with accounts payable to CAMMESA; and (v) US$4 million of higher expenses related to fines. The foregoing was partially offset by; (i) US$27 million of lower effects on post - employment benefit obligations; (ii) US$13 million of lower financial expenses recognized from derivative transactions in the distribution companies in Brazil; (iii) US$13 million of lower capitalization of financial expenses on projects; (iv) US$7 million of lower expense incurred from transactions with related companies that are outside the consolidation perimeter; and (v) US$3 million from lower updates of PIS/COFINS tax credits. In the third quarter, financial expenses increased by US$61 million mainly explained by; (i) US$73 million of higher financial expenses on bank loans mainly at Enel Colombia and in Brazil; (ii) US$30 million of expenses related to fines; (iii) US$27 million from higher update of regulatory assets and liabilities; (iv) US$5 million of higher financial expenses associated with accounts payable to CAMMESA in Argentina; (v) US$5 million of higher financial expenses recognized from derivative transactions in the distribution companies in Brazil.

(c) The results from indexation units increased by US$63 million and correspond to the financial result generated by the application of IAS 29 Financial Reporting in Hyperinflationary Economies in Argentina. They reflect the net balance arising from applying in flation to non-monetary assets and liabilities and to incom e statement accounts that are not determined on an updated basis, converted to U.S. dollars at the closing exchange rate. In the third quarter of 2026, the effect of hyperinflation in Argentina generated an increase of US$24 million in the results from indexation units account. (d) Losses from foreign exchange differences show a lower income of US$22 million when compared to the 2025 period, mainly due to; (i) US$61 million from higher loss from foreign exchange differences on derivative instruments, and (ii) US$19 million from higher loss from recognition of foreign exchange differences at Enel Generación El Chocón, which include the effect of accounts payable exposed to a devaluation process of the Argentine peso. The foregoing was partially offset by; (i) US$44 million from higher income from the update of trade accounts payable with related companies outside the consolidation perimeter; and (ii) US$13 million from higher income from foreign exchange differences from the update of trade accounts receivable and accounts payable with related companies outside the consolidation perimeter.

PRESS RELEASE CONSOLIDATED FINANCIAL STATEMENTS ENEL AMÉRICAS GROUP AS OF SEPTEMBER 30, 2026 Page 20 In the third quarter of 2026, foreign exchange differences generated a loss of US$28 million, compared to the same period of 2025, mainly explained by; (i) US$22 million from higher loss from foreign exchange differences from the update of trade accounts receivable and accounts payable with related companies outside the consolidation perimeter; (ii) US$16 million at Enel Américas, from negative foreign exchange differences associated with dividends from foreign subsidiaries and on cash and cash equivalents; (iii) US$9 million from higher loss from foreign exchange differences on derivative instruments; and (iv) US$9 million from lower foreign exchange differences at Enel Generación El Chocón. All of the foregoing was partially offset by US$28 million from higher gain from foreign exchange differences from the update of trade accounts payable with related companies outside the consolidation perimeter. Income Tax on Corporations: The income tax on corporations reached US$690 million in the period ended September 30, 2026, representing a higher tax expense of US$244 million compared to the 2025 period. This variation is mainly explained by; (i) US$172 million of higher taxes due to the increase in results of the companies in Colombia; (ii) higher taxes of US$95 million due to higher results in Brazil ; and (iii) higher taxes of US$14 million at Edesur, fundamentally explained by; (a) US$43 million of higher taxes due to better results and recognition of the effects of hyperinflation; and (b) lower taxes of US$28 million due to the lower revenue corresponding to the settlement agreement under the Special Regime for the Regularization of Obligations recorded in 2025. All of the foregoing was partially offset by; (i) US$18 million from lower taxes at Enel Generación El Chocón , associated with updates of net assets for hyperinflation; (ii) lower deferred taxes of US$14 million corresponding, mainly US$16 million from lower tax associated with dividends received from subsidiaries ; and (iii) US$4 million from lower taxes at Enel Argentina and Hidroinvest. The income tax in the third quarter of 2026 had a higher expense of US$139 million compared to the same period of 2025, which is mainly explained by US$143 million of higher taxes due to higher results in the companies of (a) Colombia for US$98 million; (b) US$17 million of higher tax of Brazilian companies; and (c) higher taxes of US$ 11 million at Edesur, fundamentally explained by the effect of inflation.

PRESS RELEASE CONSOLIDATED FINANCIAL STATEMENTS ENEL AMÉRICAS GROUP AS OF SEPTEMBER 30, 2026 Page 25 MAIN RISKS ASSOCIATED WITH THE ACTIVITY OF THE ENEL AMERICAS S.A. GROUP The Group’s activities are subject to a broad set of government regulations, and changes introduced to them could affect its activities, financial position and results of operations. The Group’s operating subsidiaries are subject to extensive regulations on tariffs and other aspects that govern their activi ties in the countries in which they operate. Consequently, the introduction of new laws or regulations, as well as the modification of existing laws or regulations, could impact their activities, financial position and results of operations. These new laws or regulations sometimes modify aspects of the regulation that may affect existing rights which, where applica ble, could have adverse effects on the Group’s future results. The Group’s activities are subject to extensive environmental regulations with which Enel Américas complies on an ongoing basis. Any modifications introduced in these matters could affect the activities, financial position and results of operations. Enel Américas and its operating subsidiaries are subject to environmental regulations, which, among other things, require env ironmental impact studies to be carried out for projects under study, the obtaining of licenses, permits and other mandatory author izations, and compliance with all requirements set forth in such licenses, permits and regulations. As with any regulated company, Enel Américas cannot guarantee that:  Public authorities will approve such environmental impact studies;  Public opposition will not result in delays or modifications of any proposed project;  Laws or regulations will not be modified or interpreted in such a way as to increase expenses or affect the operations, plants or plans of the Group companies. The Group’s business activity has been planned to moderate potential impacts arising from changes in hydrological conditions. The operations of the Enel Américas group include hydroelectric generation and, therefore, depend on the hydrological conditi ons that exist at any given time in the broad geographic areas where the Group’s hydroelectric generation facilities are located. I f hydrological conditions produce droughts or other conditions that negatively influence hydroelectric generation activity, results could be adversely affected, which is why Enel Américas has defined as an essential part of its commercial policy not to contract 100% of its total capacity. In turn, the electricity business is affected by atmospheric conditions such as average temperatures that determine consumption. As is standard practice in bank loans and in capital market transactions, a portion of the financial indebtedness of Enel Américas is subject to cross-default provisions. If certain defaults are not cured, they could result in a cross default and, eventually, certain liabilities of Enel Américas could become due and payable. In relation to the credit line under New York State law, entered in September 2026 and maturing in September 2028, its early repayment could be triggered following the non-payment – after any applicable grace period – of debts of Enel Américas whose individual outstanding principal exceeds the equivalent of US$150 million. In addition, this credit line contains provisions under which certain events other than non-payment, at Enel Américas, such as bankruptcy, insolvency, final adverse court judgments for an amount exceeding US$300 milli on, among others, could cause the declaration of its acceleration. With respect to the Yankee bonds issued in 2016, maturing in 2026, their mandatory early repayment could be triggered due to the non- payment – after any applicable grace period – of any debt of Enel Américas individually or of any Significant Subsidiary (a s contractually defined) with a principal amount exceeding US$150 million, or its equivalent in other currencies. Whereas in the specific case of the Yankee bond issued in 1996, maturing in 2026, early repayment is triggered only by the default on payment of individual debt for an amount of US$30 million, or its equivalent in other currencies, by the Issuer or Debtor, with no reference to its foreign subsidiaries. There are no clauses in the credit agreements under which changes in the corporate or debt credit rating of Enel Américas, by the rating agencies, give rise to the obligation to make debt prepayments. For further background on the risk management policy, see Note 21 of the Consolidated Financial Statements of Enel Américas a s of September 30, 2026.

PRESS RELEASE CONSOLIDATED FINANCIAL STATEMENTS ENEL AMÉRICAS GROUP AS OF SEPTEMBER 30, 2026 Page 26 BOOK VALUE AND ECONOMIC VALUE OF ASSETS Regarding the most important assets, the following should be mentioned: Property, plant and equipment are generally measured at their acquisition cost, net of the corresponding accumulated depreciation and of any impairment losses they have experienced. Property, plant and equipment, net of its residual value where applicable , is depreciated by distributing the cost of the different elements that comprise it on a straight-line basis over the estimated useful life years, which constitute the period in which the companies expect to use them. Such estimated useful life is reviewed periodically. Goodwill (lower value of investments or goodwill) generated in the consolidation represents the excess of the acquisition cost over the Group’s share in the fair value of the identifiable assets and liabilities, including contingent liabilities and the non -controlling interest, of a subsidiary company, at the acquisition date. Goodwill is not amortized, but at the close of each accounting period an estimate is made of whether any impairment has occurred that would reduce its recoverable amount to an amount lower than the recorded net cost, proceeding, where applicable, to the corresponding impairment adjustment (See Note 3.e) of the Consolidated Financial Statements. Throughout the year and mainly at its closing date, the Group assesses whether there is any indication that an asset may have suffered an impairment loss or a reversal thereof. If any indication exists, an estimate is made of the recoverable amount of such asset in order to determine, where applicable, the amount of the impairment. If these are identifiable assets that do not generate cash flows independently, the recoverability of the Cash-Generating Unit (CGU) to which the asset belongs is estimated, understood as the smallest identifiable group of assets that generates independent cash inflows. Assets expressed in foreign currency are presented at the exchange rate in effect at the close of the year. Accounts and notes receivable from related companies are classified according to their maturity as short and long term. Transactions are conducted under arm’s-length conditions similar to those prevailing in the market. In summary, assets are presented valued in accordance with International Financial Reporting Standards, whose criteria are set out in Notes No. 2 and 3 of the Consolidated Financial Statements of Enel Américas as of September 30, 2026.
