‌Note 1 | General information

Empresa Distribuidora y Comercializadora Norte S.A. (hereinafter "edenor" or "the Company") is a corporation (sociedad anónima) organized under the laws of the Argentine Republic, with legal address at 6363 Av. Del Libertador Ave - City of Buenos Aires, Argentina, whose shares are listed on Bolsas y Mercados Argentinos S.A. (ByMA) (Argentine Stock Exchange and Securities Market), traded on Mercado Abierto Electrónico S.A. (MAE) (electronic securities and foreign currency trading market), and the New York Stock Exchange (NYSE).

The Company's corporate purpose is to engage in the provision of electricity distribution and sale services within the concession area and under the terms of the Concession Agreement by which this public service is regulated. The Company may also provide and/or sale telecommunication services; subscribe or acquire shares of other companies; hold equity interests in other companies engaged in activities related to the distribution and sale of electric power and/or the generation of electric power, whether renewable or conventional, critical minerals, digitalization, and/or artificial intelligence; provide advisory, training, operation and maintenance, consulting and management, and research and analysis services; as well as assign, for valuable consideration or free of charge, specialized know-how acquired in the development of its business activities.

The Company's economic and financial situation

The Company's economic performance has continued its trend of improvement during the first three months of this period. Since 2024, the electricity rate increases, including the approval of the 2025-2030 Electricity Rate Review, have helped restore the Company's financial and cash structure. Furthermore, it is worth pointing out that during this period, the automatic monthly periodic adjustments have continued, using the CPD inflation adjustment formula (33% based on the consumer price index (IPC) and 67% based on the wholesale price index (IPIM)), plus 0.42% above inflation in real terms, with average increases of 3%.

Additionally, and taking into consideration the expansion of the corporate purpose carried out in 2024, aimed at providing greater flexibility and actively capturing new business opportunities arising from the energy transition and sustainable mobility, the Company is currently evaluating the acquisition of other energy assets in accordance with its strategic plan to diversify, expand, and capitalize on opportunities in the energy sector, with the aim of strengthening its position in the energy industry and realizing long-term growth opportunities, including the potential acquisition-whether direct or indirect by the Company-of businesses in the power, electricity transmission, and hydrocarbons sectors, including complementary assets in the sale, final refining, and/or distribution (downstream) of hydrocarbons, oil, and their derivatives, as well as the distribution and sale of natural gas, thus allowing for the integration of businesses in this new context.

Finally, taking into consideration the impact of the electricity rate adjustments implemented, the results of operations for the period continue to reflect an improvement in the Company's operational and financial performance. Within this framework, the Company has continued to make the investments necessary to maintain grid reliability and enhance service quality through technology and innovation, aimed at more efficient energy use.

‌Note 2 | Regulatory framework

At the date of issuance of these condensed interim consolidated financial statements, there exist the following changes with respect to the situation reported by the Company in the Consolidated Financial Statements as of December 31, 2025:

1. Electricity rate situation

   On March 30, 2026, by means of Resolution No. 198/2026, the ENRE approved the values of the Company's electricity rate schedule effective from the billing relating to the reading of meters subsequent to 12:00 AM on April 1, 2026, with a 2.04% increase in the CPD.

   Furthermore, on April 30, 2026, by means of Resolution No. 109/2026, the SE approved the values of the Seasonal Price of Energy and the Power Reference Price, along with the definitive Winter Seasonal Programming for the MEM submitted by CAMMESA, relating to the May 1, 2026-October 31, 2026 period. In line with this, on May 4, 2026, by means of Resolution No. 243/2026, the ENRE approved the values of the Company's electricity rate schedule effective from the billing relating to the reading of meters subsequent to 12:00 AM on May 1, 2026, with a 4.1% increase in the CPD.

2. Agreements on the Regularization of Payment Obligations with CAMMESA - Debt for the purchase of energy in the MEM

   As of March 31, 2026, the debts payable relating to: (i) the Payment plan signed on December 29, 2022; (ii) the Payment plan signed on July 28, 2023 and converted into Argentine pesos on May 21, 2025; and (iii) the new Payment plan signed on the previously mentioned date, amount to $ 89,783,

   $ 116,439 and $ 189,476, respectively, and have been disclosed in the current and non-current Other payables account within the Statement of Financial position.

3. Framework Agreement

   On March 19, 2026, the Company and the Federal Government entered into a new agreement on the recognition of electricity consumption in vulnerable neighborhoods of the Province of Buenos Aires for the 2024-2026 period. This consumption represents 57.53% of the total consumption to be jointly recognized by the Federal Government and the Province. In this regard, the aforementioned consumption is supplied at the cost of energy, transmission and the FNEE, excluding the VAD.

   The above-mentioned agreement sets forth the consumption amounts to be recognized for 2024 and 2025 (January-October period), totaling $ 7,708 and $ 12,732, respectively; the offsetting thereof against the invoice for energy purchases from the MEM, and the carrying out of certain works in accordance with the annual investment plan, already completed by the Company in a timely manner.

   Regarding consumption for the November-December 2025 period and for 2026, the amounts to be recognized are to be defined in order to subsequently proceed based on the provisions set forth in the aforementioned agreement.

   Furthermore, the Company requested that the Infrastructure Ministry of the Province of Buenos Aires initiate the necessary administrative procedures in order to formalize an agreement for the 2024-2026 period, relating to the remaining 42.47% of the total consumption. At the date of issuance of these condensed interim consolidated financial statements, said agreement has not been formalized.

   As of March 31, 2026, the Company has recognized income of $ 20,440 relating to the total amounts recognized, which is disclosed in the Other operating income account, within the Statement of Comprehensive Income.

   Finally, on May 4, 2026, the National Economy Ministry, through the Energy Secretariat, instructed CAMMESA to apply the amount of $ 7,708 to offset the invoice for energy purchases from the MEM.

   ‌Note 3 | Basis of preparation

   These condensed interim consolidated financial statements for the three-month period ended March 31, 2026 have been prepared in accordance with the provisions of IAS 34 "Interim Financial Reporting". They were approved for issue by the Company's Board of Directors on May 8, 2026.

   By means of General Resolution No. 622/2013, the CNV provided for the application of Technical Resolution No. 26 of the FACPCE, which adopts the IFRS Accounting Standards issued by the IASB, for those entities that are included in the public offering system of Law No. 17,811, as amended, whether on account of their capital or their corporate notes, or have requested authorization to be included in the aforementioned system.

   These condensed interim consolidated financial statements include all the necessary information in order for the users to properly understand the relevant facts and transactions that have occurred subsequent to the issuance of the last Consolidated Financial Statements for the year ended December 31, 2025 and until the date of issuance of these condensed interim consolidated financial statements. The Company's Management estimates that they include all the necessary adjustments to fairly present the results of operations for each period. The results of operations for the three-month period ended March 31, 2026 and its comparative period as of March 31, 2025 do not necessarily reflect the Company's results in proportion to the full fiscal year. Therefore, the condensed interim consolidated financial statements should be read together with the audited Consolidated Financial Statements as of December 31, 2025 prepared under IFRS Accounting Standards.

   The Company's condensed interim consolidated financial statements are measured in pesos (the legal currency in Argentina), restated in accordance with that mentioned in this Note, which is also the presentation currency.

   Comparative information

   The balances as of December 31 and March 31, 2025, as the case may be, disclosed in these condensed interim consolidated financial statements for comparative purposes, arise as a result of restating the annual Consolidated Financial Statements and the Condensed Interim Consolidated Financial Statements as of those dates, respectively, to the purchasing power of the currency at March 31, 2026, as a consequence of the restatement of financial information described hereunder. Furthermore, in addition to the situation reported in Note 1, certain amounts of the financial statements presented in comparative form have been reclassified in order to maintain consistency of presentation with the amounts of the current periods.

   Restatement of financial information

   The condensed interim consolidated financial statements, including the figures relating to the previous year/period, have been stated in terms of the measuring unit current at March 31, 2026, in accordance with IAS 29 "Financial reporting in hyperinflationary economies", using the indexes published by the FACPCE. The inflation rate for the period of January 1, 2026 - March 31, 2026 was 9.4%.

   Segment information

   edenor's main activity consists of the provision of electricity distribution and sale services within the concession area. As of March 31, 2026, all the Company's revenues, expenses, assets and liabilities are associated with a single operating and geographical segment. Accordingly, no additional disaggregation by business segment is presented, as internal management and decision-making are conducted based on a single segment.

   The information disclosed in these condensed interim consolidated financial statements is presented in a single segment and refers to the entire Company.

   ‌Note 4 | Accounting policies

   The accounting policies adopted for these condensed interim consolidated financial statements are consistent with those used in the Consolidated Financial Statements for the last financial year, which ended on December 31, 2025.

   New accounting standards, amendments and interpretations issued by the IASB that are effective as of March 31, 2026 and have been adopted by the Company

   • IFRS 7 "Financial Instruments: Disclosures" and IFRS 9 "Financial Instruments", amended in May 2024. The amendments address matters identified during the post-implementation review of the classification and measurement requirements of financial instruments. The application of these amendments impacted neither the Company's results of operations nor its financial position.

   • Annual improvements to IFRS - Volume 11, issued in July 2024. It contains amendments to IFRS 1 "First-time adoption of IFRS", IFRS 7 "Financial Instruments: Disclosures", IFRS 9 "Financial Instruments", IFRS 10 "Consolidated Financial Statements" and IAS 7 "Statement of Cash Flows". The application of these amendments impacted neither the Company's results of operations nor its financial position.

     There are no new IFRS Accounting Standards or IFRIC applicable as from this period that

     have a material impact on the Company's condensed interim consolidated financial statements.

     New accounting standards, amendments and interpretations issued by the IASB that are not yet effective and have not been early adopted by the Company

     In accordance with Title IV, Chapter III, Section 1 of CNV Regulations, the early adoption of IFRS and/or their amendments is not permitted, unless specifically allowed at the time of adoption.

   • IFRS 18 "Presentation and disclosure in financial statements", issued in April 2024. It includes new requirements for all entities applying IFRS for the presentation and disclosure of information in financial statements. It introduces three defined categories of income and expenses (operating, investing and financing) that modify the structure of the statement of profit or loss, and requires companies to present new defined subtotals, including operating profit or loss, in order to analyze the companies' financial performance and facilitate comparison between companies. The standard requires companies to disclose explanations of those company-specific measures that are related to the statement of profit or loss, referred to as management-defined performance measures. It provides enhanced guidance on how to organize information and whether to provide it in the primary financial statements or in the notes. It requires that companies provide more transparency about operating expenses. The management-defined performance measures, as defined by IFRS 18, consist of measures that are subtotals of income and expenses. IFRS 18 does not require companies to provide management-defined performance measures but does require companies to explain them if they are provided.

     IFRS 18 replaces IAS 1 "Presentation of financial statements" but carries forward many requirements from IAS 1 unchanged. IFRS 18 is effective for annual reporting periods beginning as from January 1, 2027, with early adoption permitted. In this regard, the Company is currently assessing the impact of IFRS 18 and estimates that there will be significant changes in the disclosure of the Statement of Comprehensive Income and its related notes.

   • IFRS 19 "Subsidiaries without public accountability: Disclosures", issued in May 2024. It specifies reduced disclosure requirements that an eligible entity is permitted to apply instead of the disclosure requirements in other IFRS. IFRS 19 is effective for annual reporting periods beginning as from January 1, 2027, with early adoption permitted.

   • IAS 21 "The effects of changes in foreign exchange rates", amended in November 2025. It clarifies how companies should translate their financial statements from a non-hyperinflationary currency into a hyperinflationary one. The amendments are effective for annual reporting periods beginning as from January 1, 2027.

   ‌Note 5 | Financial risk management Note 5.1 | Financial risk factors

   The Company's activities and the market in which it operates expose the Company to a number of financial risks: market risk (including currency risk, cash flows interest rate risk, fair value interest rate risk and price risk), credit risk and liquidity risk.

   Additionally, the difficulty in obtaining financing in international or national markets could affect certain variables of the Company's business, such as interest rates, foreign currency exchange rates and the access to sources of financing.

   With regard to the Company's risk management policies, there have been no significant

   changes since the last fiscal year-end.

         (1) The exchange rates used are the BNA exchange rates in effect as of March 31, 2026 for United States dollars (USD), and Euros (EUR).

      2. Fair value estimate

         The Company classifies the measurements of financial instruments at fair value using a fair value hierarchy that reflects the relevance of the variables used for carrying out such measurements. The fair value hierarchy has the following levels:

         • Level 1: quoted prices (unadjusted) in active markets for identical assets or liabilities.

         • Level 2: inputs other than quoted prices included in Level 1 that are observable for the asset or liability, either directly (i.e. prices) or indirectly (i.e. derived from the prices).

         • Level 3: inputs for the asset or liability that are not based on observable market data (i.e. unobservable inputs).

         The table below shows the Company's financial assets and liabilities measured at fair value

         as of March 31, 2026 and December 31, 2025:

         LEVEL 1 LEVEL 3

         At March 31, 2026 Assets
         Other receivables Assigned assets and in custody	17,111		-

         Mutual funds	475,857		-
         Shares	-		58,756
         Cash and cash equivalents Mutual funds	66,273		-
         Total assets	704,595		58,756

         As of March 31, 2026, the Company has investments in equity instruments relating to minority interests in unlisted companies, engaged in the development of early-stage mining projects. As there is no active market for these shares, their fair value was classified within Level 3 of the hierarchy established by IFRS 13.

         The fair value of these investments was determined on the basis of valuation reports prepared by independent experts, using a market approach based on recent comparable transactions involving properties at similar exploration stages, adjusted for specific conditions, such as location, degree of geological development, and macroeconomic environment. The applied method consisted of using per-hectare multiples, weighted according to the aforementioned factors.

         Significant unobservable variables

         Among the key unobservable inputs included in the valuation, the following stand out:

         • Market value per hectare adjusted for geological prospectivity.

         • Project development stage (pre-exploration or initial exploration).

         • Exclusion of transactions in non-applicable geographic regions.

         The properties comprise projects at the initial stage of exploration in the lithium, copper, and gold sectors, located in regions with high mining activity and strong discovery potential, such as the province of Catamarca (mountain range area and western salt flats) and border areas between Argentina and Chile. Due to the fact that most of these properties show little or no exploration development, and that there is no active market for this type of assets, their valuation was determined based on third-party comparable transactions carried out over the last five years. These transactions were adjusted according to the exploration stage, location, and other particular conditions of each project.

         For lithium-related properties, mainly located in salt flats and brine areas, reference values range from USD 80 to USD 985 per hectare, taking into account geological prospectivity and the limited available information. As for copper and gold projects, located in areas with early exploration activity and high potential but without defined resources, the range considered varies between USD 200 and USD 1,000 per hectare, using comparable transactions in the region as a reference.

         Sensitivity

         Due to the fact that the fair value estimate is subject to significant uncertainties arising from the absence of an active market for these assets, reasonable changes in the variables used (for example, variations in reference multiples or in the assessment of the geological potential) could significantly impact the value assigned to the investments (Note 19).

      3. Interest rate risk

         Interest rate risk is the risk of fluctuation in the fair value or cash flows of an instrument due to changes in market interest rates. The Company's exposure to interest rate risk is mainly related to its long-term debt obligations.

         Indebtedness at floating rates exposes the Company to interest rate risk on its cash flows. Indebtedness at fixed rates exposes the Company to interest rate risk on the fair value of its liabilities. As of March 31, 2026, with the exception of both the Class No. 9 Corporate Notes issued by the Company in Argentine pesos, at a TAMAR floating interest rate plus an annual 6% fixed margin, and the bank loans in Argentine pesos (Note 25), all loans were obtained at fixed interest rates. The Company's policy is to keep the largest percentage of its indebtedness in instruments that accrue interest at fixed rates.

         ‌Note 6 | Critical accounting estimates and judgments

         The preparation of the condensed interim consolidated financial statements requires the Company's Management to make estimates and assessments concerning the future, exercise critical judgment and make assumptions that affect the application of the accounting policies and the reported amounts of assets and liabilities and revenues and expenses.

         These estimates and judgments are permanently evaluated and are based upon past experience and other factors that are reasonable under the existing circumstances. Future actual results may differ from the estimates and assessments made at the date of preparation of these condensed interim consolidated financial statements.

         In the preparation of these condensed interim consolidated financial statements, there were no changes in either the critical judgments made by the Company when applying its accounting policies or the sources of estimation uncertainty used with respect to those applied in the Consolidated Financial Statements for the year ended December 31, 2025.

         ‌Note 7 | Contingencies and lawsuits

         The provision for contingencies has been recorded to face situations existing at the end of each period that may result in a loss for the Company if one or more future events occurred or failed to occur.

         At the date of issuance of these condensed interim consolidated financial statements, there are no significant changes with respect to the situation reported by the Company in the Consolidated Financial Statements as of December 31, 2025.

         ‌Note 8 | Revenue from sales and energy purchases

         We provide below a brief description of the main services provided by the Company:

         Sales of electricity Small demand segment:

         Residential use and

         public lighting (T1)

         Medium demand segment: Commercial and industrial customers (T2) Large demand segment (T3)

         Other: (Shantytowns/ Wheeling system)

         Relates to the highest demand average recorded over 15 consecutive minutes that is less than 10 kilowatts. In turn, this segment is subdivided into different residential categories based on consumption. This segment also includes a subcategory for public lighting.

         Revenue is recognized in the period in which the service provided to certain shantytowns is accrued. In the case of the service related to the Wheeling system, revenue is recognized when the Company allows third parties (generators and large users) to access the available transmission capacity within its distribution system upon payment of a wheeling fee.

         The KWh price relating to the Company's sales of electricity is determined by the ENRE by means of the periodic publication of electricity rate schedules (Note 2.a), for those distributors that are regulated by the aforementioned Regulatory Authority, based on the rate setting and adjustment process set forth in the Concession Agreement.

         Other services Right of use of poles

         Connection and reconnection charges

         Energy purchases

         Energy purchase

         Energy losses

         The Company bills its users the cost of its purchases of energy, which includes charges for purchases of energy and power. The Company purchases electric power at seasonal prices approved by the SE. The price of the Company's electric power reflects the costs of transmission and other regulatory charges.

         Energy losses are equivalent to the difference between energy purchased and energy sold. These losses can be classified into technical and non-technical losses. Technical losses represent the energy lost during transmission and distribution within the network as a consequence of the natural heating of the conductors and transformers that carry electricity from power generation plants to users. Non-technical losses represent the remainder of the Company's energy losses and are mainly due to the illegal use of its services or the theft of energy. Energy losses require that the Company purchase additional energy in order to meet the demand and its Concession Agreement allows it to recover from its users the cost of these purchases up to a loss factor specified in its concession for each rate category. The current loss factor recognized in the tariff by virtue of its concession amounts approximately to 10%.

         The non-current shares relate to acquisitions of minority interests in the share capital of two companies engaged in the development of mining projects aimed at the exploration of critical minerals, such as lithium and copper, at an early-stage or pre-exploration phase, in the province of Catamarca, whose adjacent areas show high prospectivity. Those acquisitions represent 15% and 40% of those companies' share capital, with political rights in the latter case being limited to 11.8%. The Company has recognized these investments at their fair value in accordance with IFRS 9.

         The fair value of the shares as of March 31, 2026 amounts to $ 50,976 and has been determined on the basis of valuation reports prepared by independent experts, which take into consideration third-party comparable transactions involving properties at similar exploration stages. Due to the fact that there is no active market for the shares, a per-hectare multiples approach was used, adjusted for geological characteristics, location and market conditions. The applicable fair value category is Level 3 (Note 5).

         Based on the guidelines provided for in IFRIC 23 "Uncertainty over income tax treatments", the Company has restated for inflation the cumulative tax losses and fixed assets depreciation for additions prior to January 1, 2018, using the wholesale price index, general level (IPIM) and the consumer price index, general level (IPC), respectively. This criterion has been adopted taking into consideration that the effective income tax rate shows a confiscatory result, in line with the Supreme Court of Justice of Argentina's decision rendered in the case entitled "Telefónica de Argentina SA and Another vs/EN-AFIP-DGI, General Tax Bureau" on October 25, 2022.

To the Shareholders, President and Directors of Empresa Distribuidora y Comercializadora Norte Sociedad Anónima (Edenor S.A.)

We have reviewed the accompanying condensed consolidated interim statement of financial position of Empresa Distribuidora y Comercializadora Norte Sociedad Anónima (Edenor S.A.) and its subsidiaries (the 'Group') as at March 31, 2026 and the related condensed consolidated interim statements of comprehensive income, changes in equity and cash flows for the three-month period then ended and selected explanatory notes.

The board of Directors is responsible for the preparation and presentation of this condensed consolidated interim financial information in accordance with IFRS Accounting Standards and is therefore responsible for the preparation and presentation of the condensed interim financial statements mentioned in the first paragraph, in accordance with International Accounting Standard 34 (IAS 34).

We conducted our review in accordance with International Standard on Review Engagements 2410, 'Review of interim financial information performed by the independent auditor of the entity'. A review of interim financial information consists of making inquiries, primarily of persons responsible for financial and accounting matters, and applying analytical and other review procedures. A review is substantially less in scope than an audit conducted in accordance with International Standards on Auditing and consequently does not enable us to obtain assurance that we would become aware of all significant matters that might be identified in an audit. Accordingly, we do not express an audit opinion.
