FINANCIAL STATEMENTS ANALYSIS ENEL CHILE GROUP AS OF MARCH 31, 2026

FINANCIAL SUMMARY- ENEL CHILE

The Company’s gross financial debt increased by US$ 41 million compared to December 2025, totaling US$ 3,882 million. This change is explained by the following:

Enel Chile’s available liquidity breaks down as follows:

The average cost of debt in March 2026 remained at 4.9% compared to December 2025.

Hedging and protection:

In order to mitigate the financial risks associated with exchange rate and interest rate fluctuations, Enel Chile has established policies and procedures to protect its financial statements against the volatility of these variables.

Enel Chile’s foreign exchange risk hedging policy stipulates that there must be a long-term balance between the currency in which each company’s cash flows are denominated and the currency in which they borrow. Consequently, as of today, the Enel Chile Group has cross-currency swap contracts totaling US$ 170 million and forward contracts totaling US$ 305 million.

To reduce the volatility of the financial statements due to changes in interest rates, the Enel Chile Group maintains an appropriate balance in its debt structure, for which it has interest rate swap contracts totaling US$ 286 million.

INFORMATION RELEVANT TO THE ANALYSIS OF THESE FINANCIAL STATEMENTS

Regulatory Changes:

On December 14, 2020, the National Energy Commission (CNE) published Resolution No. 340 Exempt, which amended the technical provisions for the implementation of the Rate Stabilization Law. This Resolution clarified that payments to each supplier “must be applied to outstanding balances in chronological order, starting with the oldest balances and moving to the newest,” rather than on a weighted basis across the total outstanding balances, as the industry had interpreted up to that point.

In addition, this Resolution established that the payment of balances will be made using the observed dollar rate on the sixth business day following the publication of the Coordinator’s Balance Payment Schedule, replacing the average dollar rate for the billing month, as had been established until that time.

This fund will be financed through an additional charge to end-users, segmented by consumption levels, whereby customers with monthly consumption of less than 350 kWh will be exempt from the charge, as will micro and small businesses with monthly consumption of up to 1,000 kWh.

FINANCIAL STATEMENTS ANALYSIS ENEL CHILE GROUP AS OF MARCH 31, 2026

The fund is administered by the General Treasury of the Republic and will receive an annual government contribution of US$20 million from 2023 until the end of its term on December 31, 2032, in addition to the US$15 million contributed in 2022. All surpluses generated in excess of the US$1.35 billion fund specified in Law 21,185 are recognized as part of the mechanism established in Law No. 21,472.

On March 14, 2023, the CNE published Exempt Resolution No. 86, which establishes the technical provisions for the implementation of Law No. 21,472. Subsequently, on August 9, 2023, the CNE issued Exempt Resolution No. 334, which amends Exempt Resolution No. 86, establishing, among other matters, certain provisions, procedures, deadlines, and conditions for the proper implementation of the aforementioned Law.

In February 2024, the limit of US$ 1.8 billion in accounts receivable from regulated customers established by Law No. 21,472 was reached.

On the other hand, customers with monthly consumption exceeding 350 kWh/month will pay the actual price of energy and capacity starting from the publication of the average base price decree for the first half of 2024, plus an additional charge (MPC charge) that will allow for the repayment of the debt accumulated by the PEC and MPC. In turn, customers with consumption of 350 kWh or less per month will pay the actual price of energy and capacity starting from the publication of the average base price decree for the second half of 2024, and beginning with the decree for the first half of 2025, the MPC charge will be added.

FINANCIAL STATEMENTS ANALYSIS ENEL CHILE GROUP AS OF MARCH 31, 2026

The deadline for submitting comments on the aforementioned ITP expired on October 24 of 2025.

As of the date of issuance of these consolidated financial statements, the Company is evaluating the potential implications of this proposed change in the methodology identified by the CNE, pending the Final Technical Report for the Setting of Node Prices.

Change of functional currency and reporting currency:

The change in the presentation currency at Enel Chile was accounted for as a change in accounting policy and applied retrospectively, as if the new presentation currency had always been the presentation currency of the consolidated financial statements. For further information, please refer to Note No. 3 of Enel Chile’s Consolidated Financial Statements as of March 31, 2026.

As of March 31, 2026, net income attributable to Enel Chile shareholders amounted to US$ 162 million, representing a decrease of US$ 12 million, or 7.0%, compared to the previous year. This decrease is primarily due to higher expenses in the financial result, which offset the improved operating income recorded during the period.

The main factors explaining this result are described below:

§     An increase in financial expenses of US$ 11 million, mainly explained by: (i) a decrease in capitalization of interest of US$ 9 million, primarily in the Generation Segment, resulting from the commissioning of the Los Cóndores power plant during the first quarter of 2025; and (ii) an increase in financial costs from payment schedule optimization agreements with suppliers of US$ 4 million.

§     An increase in foreign exchange rate differences losses of US$ 32 million compared to the same period in 2025, primarily due to: (i) an increase in negative foreign exchange rate differences on accounts receivable and payable with related parties of US$ 33 million; (ii) an increase in negative foreign exchange rate differences on trade accounts of US$ 42 million; and (iii) an increase in negative foreign exchange rate differences on cash and cash equivalents of US$ 8 million. This was partially offset by: (i) a decrease in negative foreign exchange rate differences on derivative instruments of US$ 47 million; and (ii) an increase in positive foreign exchange rate differences on other financial assets of US$ 4 million.

§     A decrease in income from indexed units of US$ 6 million compared to the same period in 2025, mainly explained by: (i) a decrease in income from the adjustment of trade receivables of US$ 2 million; and (ii) a decrease in income from the adjustment of tax assets of US$ 4 million.

Corporate income tax

Corporate income tax amounted to a loss of US$ 68 million for the period ended March 31, 2026, representing an increase in expense of US$ 5 million compared to the same period of the prior year. This variation is primarily due to an increase in tax expense of US$ 3 million resulting from price-level restatement.

Enel Chile Group generated positive net cash flow of US$ 5 million for the period ended March 31, 2026, representing an improvement of US$ 4 million in net cash flow compared to the same period in 2025. The main factors explaining this higher positive net cash flow for the period are described below:

Operating activities generated a net cash inflow of US$ 175 million for the period ended March 31, 2026. These cash flows consist primarily of: (i) cash inflows from sales of goods and services of US$ 1,778 million; (ii) proceeds from the lease and subsequent sale of those assets of US$ 6 million; and (iii) other proceeds from operating activities of US$ 6 million. These cash inflows were partially offset by: (i) payments to suppliers of US$ 1,452 million; (ii) other payments for operating activities of US$ 70 million, primarily for VAT and other taxes; (iii) income tax payments of US$ 50 million; (iv) payments to employees of US$ 42 million; and (v) Other cash outflows of US$ 1 million.

The positive change in operating cash flow of US$ 23 million compared to March 2025 is primarily explained by: (i) higher collections from sales of goods and services totaling US$ 177 million; (ii) higher other collections from operating activities totaling US$ 5 million; (iii) higher other cash inflows totaling US$ 4 million; (iv) an increase in collections from the leasing and subsequent sale of those assets of US$ 2 million. This was partially offset by: (i) an increase in payments to suppliers of US$ 109 million; (ii) an increase in other payments from operating activities of US$ 30 million; (iii) an increase in payments to employees of US$ 15 million; and (iv) an increase in income tax payments of US$ 12 million.

Investing activities generated a net cash outflow of US$ 129 million for the period ended March 31, 2026. These cash flows consist primarily of: (i) cash outflows from purchases of property, plant, and equipment totaling US$ 76 million; (ii) payments related to futures contracts, options, and swaps totaling US$ 60 million; and (iii) cash outflows from the purchase of intangible assets totaling US$ 2 million. This was partially offset by: (i) proceeds from the sale of property, plant, and equipment totaling US$ 4 million; and (ii) interest received totaling US$ 3 million.

The negative change in investing cash flow of US$ 17 million compared to March 2025 is primarily explained by an increase in payments arising from futures contracts, options, and swaps totaling US$ 60 million. This was partially offset by: (i) a decrease in purchases of intangible assets of US$ 24 million; (ii) a decrease in expenditures for the purchase of property, plant, and equipment of US$ 12 million; (iii) an increase in proceeds from the sale of property, plant, and equipment of US$ 4 million; (iv) a decrease in interest paid of US$ 1 million; and (v) an increase in interest received of US$ 1 million.

FINANCIAL STATEMENTS ANALYSIS ENEL CHILE GROUP AS OF MARCH 31, 2026

Financing activities generated a net cash outflow of US$ 41 million for the period ended March 31, 2026. These cash flows consist primarily of cash outflows for: (i) dividend payments of US$ 60 million; (ii) interest payments of US$ 23 million; (iii) partial repayment of loans with the Corporación Andina de Fomento (CAF) of US$ 50 million; and (iv) lease liability payments of US$ 6 million. This was partially offset by cash inflows from a US$ 100 million loan granted by the Corporación Andina de Fomento (CAF).

The negative change of US$ 2 million in cash flows from financing activities compared to March 2025 is primarily explained by: (i) higher repayments of bank loans totaling US$ 50 million; (ii) higher interest payments on bonds totaling US$ 12 million; and (iii) higher payments of lease liabilities totaling US$ 1 million; This was partially offset by: (i) an increase in proceeds from long-term loans of US$ 50 million; (ii) a decrease in dividend payments of US$ 10 million; and (iv) a decrease in other cash outflows of US$ 1 million.

II. MAIN RISKS ASSOCIATED WITH THE ACTIVITY OF ENEL CHILE S.A. GROUP

The Group’s activities are subject to a broad set of governmental regulations, and any changes in them could affect their activities, economic situation and operating income.

The Group’s operating subsidiaries are subject to a wide range of tariff regulations and other aspects that govern their operations in Chile. Consequently, the introduction of new laws or regulations, or the modification of current laws and regulations, could affect their operations, economic situation and operating results.

These new laws or regulations, on occasion, modify regulatory aspects that may affect existing entitlements which, as the case might be, may adversely affect the Group’s future income.

The Group’s operations are also subject to wide-ranging environmental regulations that Enel Chile continuously meets. Eventual modifications introduced to such regulations could affect its operations, economic situation and operating income.

These regulations, among other things, require the preparation and submission of Environmental Impact Studies for projects under study, obtaining licenses, permits and other mandatory authorizations and complying with all the requirements imposed by such licenses, permits and regulations. Just as with any regulated company, Enel Chile cannot guarantee that:

The Group’s commercial operations have been planned in order to mitigate possible impacts as a result of changing hydrological conditions.

The operations of Enel Chile Group include hydroelectric generation, and therefore, depend on actual hydrological conditions throughout a broad geographical area where the Group’s hydroelectric generation facilities are located. Should the hydrological conditions lead to droughts or other conditions that might negatively affect hydroelectric generation business, our results could be adversely affected, which is why Enel Chile has established, as an essential part of its commercial policy, to refrain from contractually committing 100% of its generation capacity. At the same time, the electricity business is also affected by meteorological conditions, such as temperatures, that affect consumption. Our margins may be affected by weather conditions depending on the different climate conditions.

FINANCIAL STATEMENTS ANALYSIS ENEL CHILE GROUP AS OF MARCH 31, 2026

The financial position and results of operations may be adversely affected if risk exposure to interest rate, commodity price, and foreign exchange rate is not effectively managed. For further details on the risks covered, please refer to Note 22 of Enel Chile’s Consolidated Financial Statements as of March 31, 2026, available at the following link: https://www.enel.cl/en/investors/investor-enel-chile/information-for-the-shareholder/quarterly-results.html

FINANCIAL STATEMENTS ANALYSIS ENEL CHILE GROUP AS OF MARCH 31, 2026

III. BOOK VALUE AND ECONOMIC VALUE OF ASSETS

The following are the most important assets:

Property, plant, and equipment are valued at their acquisition cost, net of the corresponding accumulated depreciation, and impairment losses. The property, plant, and equipment, net of their residual value, depreciate by distributing the cost of their different components linearly over the years of the estimated useful life of the asset, which is the period in which the companies expect to use them. The estimated useful life of the asset is reviewed periodically.

Goodwill (lower value of investments or commercial funds) generated in the consolidation, represents the excess acquisition cost over the Group’s participation in the fair value of assets and liabilities, including contingent liabilities and any non-controlling, identifiable shareholdings in a subsidiary, as of the date of acquisition. Goodwill is not amortized, but at the end of each accounting period an estimation of any impairment that might reduce its recoverable value to an amount below the recorded net cost is calculated, in which case an adjustment is made for the impairment. For additional information see Note 4.e. of the Financial Statements as of March 31, 2026.

Throughout the year and, primarily at its closing date, an evaluation is carried out to determine whether any asset might have suffered an impairment loss. In the event that there is an indication of such loss, an estimate of the recoverable value of such asset is made to determine the amount of the impairment. In the case of identifiable assets that do not generate cash flows independently, an estimate is made of the recoverable amount of the cash-generating unit to which the asset belongs, which is considered to be the smallest group of assets that generate cash inflows independently.

Assets denominated in foreign currencies are presented at the exchange rate prevailing at the end of the period.

Accounts and notes receivable from related companies are classified according to their maturity in short-term and long-term. Transactions are adjusted to conditions prevailing in the market.

In summary, asset values are determined according to the International Financial Reporting Standards, whose criteria are included in Notes No. 2, 3 and 4 of the Financial Statements of Enel Chile as of March 31, 2026, available at the following link: https://www.enel.cl/en/investors/investor-enel-chile/information-for-the-shareholder/quarterly-results.html
