Enel Chile's exchange rate risk hedging policy establishes that there must be a long-term balance between the currency in which each company's cash flows are indexed and the currency in which it borrows. Therefore, to date, the Enel Chile Group has cross currency swap contracts for US$ 203 million and forwards for US$ 670 million. In order to reduce the volatility of the financial interest rate swap contracts for US$ 286 million. -4-

FINANCIAL STATEMENTS ANALYSIS ENEL CHILE GROUP AS OF SEPTEMBER 30, 2025 INFORMATION RELEVANT TO THE ANALYSIS OF THESE FINANCIAL STATEMENTS Regulatory Changes: > As part of the social agenda announced by the government, the Ministry of Energy published Law 21,185 (hereafter the “Tariff Stabilization Law”) in the Official Gazette on November 2, 2019. This Law creates a Temporary Regulated Customer Tariff Stabilization Mechanism that states that the price to charge regulated customers for electricity from July 1, 2019, through December 31, 2020, is to be equal to the prices in force during the first semester of 2019 (Decree 20T/2018). This stabilized price was named the “Stabilized Regulated Customer Price” PEC (in its Spanish acronym). From January 1, 2021, until the stabilization mechanism is suspended, the prices will be those defined in the tariff setting processes carried out every six months as established in Article 158 of the Electricity Law, but not to exceed the PEC adjusted by inflation according to the Consumer Price Index as of January 1, 2021, using the same date as base (adjusted PEC). The billing differences until 2023 are to be recorded as accounts receivables in favor of generation companies, limited to a maximum US$ 1,350 million. This limit was reached in January 2022. The balance of these accounts receivable is to be recovered, at the latest, by December 31, 2027. On December 14, 2020, the National Energy Commission (“CNE” in its Spanish acronym) published Exempt Resolution No. 340 that modified the technical provisions regarding the implementation of the Tariff Stabilization Law. This Resolution clarified that the payment to each supplier “must be booked against the Balance in a chronological manner, beginning with the most dated to the most recent pending Balances”, and not weighted based on the total Balance pending payment as it had been interpreted by the industry up to such date.

It is to receive a US$ 20 million fiscal contribution every year until its expiration date set at December 31, 2032, in addition to the US$ 15 million contribution made in 2022. The amount accumulated in excess of the US$ 1,350 million fund established in Law No. 21,185 is subject to this new mechanism created by Law No. 21,472. On March 14, 2023, the National Energy Commission published Exempt Resolution 86 that establishes technical provisions regarding the implementation of Law No. 21,472. On August 9, 2023, the CNE issued Exempt Resolution No. 334 that amends and restates the text of Exempt Resolution No. 86 indicating, among other issues, certain provisions, procedures, terms and conditions to adequately implement such Law. The US$ 1.8 billion regulated customer accounts receivable limit established by Law No. 21,472 was reached in February 2024. > On April 30, 2024, Law No. 21,667 was enacted in Chile and, among other things, establishes the following: - Tariffs for regulated customers are allowed to gradually increase reflecting the real costs of energy and capacity and consequently putting an end to the accumulation of debt by power generators. - Power generators are to recover the balance of debt they accumulated under price stabilization mechanisms PEC and MPC established by Law No. 21,185 and Law No. 21,472, respectively. - An additional US$ 5,500 million is added to the MPC fund, of which US$ 3,700 million will have a 30% state guarantee. It is to be repaid, at the latest, by December 31, 2035. - Most vulnerable customers are to benefit from an electricity subsidy to cover tariff increases.

As of the date of issuance of these consolidated financial the Final Technical Report for the Setting of Node Prices. Change of functional currency and reporting currency: > Effective January 1, 2025, Enel Chile changed its functional currency from Chilean pesos to United States dollars, as the US currency became the currency that significantly influences the economic environment in which the Company operates. The analysis that determined the change in functional currency was completed during the last quarter of the previous year and was disclosed in Enel Chile's consolidated financial statements as of December 31, 2024. This change in functional currency was mainly due to the fact that, also on January 1, 2025, its subsidiary Enel Generación Chile changed its functional currency from Chilean pesos to US dollars. This was mainly due to the fact that, as of 2025, the main source of income of said subsidiary will originate from the group of free customer contracts, which, considering the billing and collection cycles, give rise to substantially lower exposure to exchange rate fluctuations compared to the group of regulated customers, which require a much longer time to complete the collection process. The group of regulated customer contracts represented the Company's main source of income until fiscal year 2024. Thus, considering the relevance of the generation segment for the Group, Enel Chile's main source of income, i.e., dividends from its subsidiaries, will have a consistent determination basis in United States dollars. It is important to note that, until the end of 2024, the Company maintained certain operations defined as cash flow hedges, w
