IMPROVED FINANCIAL PERFORMANCE EARNING RELEASE FOURTH QUARTER 2025 02 FINANCIAL RESULTS EARNINGS RELEASE FOURTH QUARTER 2025 Revenues: Rose to ARS 706,123 million in 4Q25 (+4% in constant currency vs. 4Q24). This was mainly due to the tariff regularization including the impact of February 2024 tariff adjustment (319.2%) and subsequent monthly adjustments since August 2024 (3.1% on average). The number of clients at 4Q25 reached 3.39 million (+1% vs. 4Q24). Energy Purchases: Reached ARS 385,999 million in 4Q25, representing a 1% decrease compared to the ARS 391,206 million recorded in the same period of the previous year, with a cumulative total of ARS 1,737,629 million (+13% vs. 12M24). The variation as of December 2025 is mainly explained by a rise in demand, higher generation prices, and a reduction in subsidies. Distribution Margin: Reached ARS 320,124 million in 4Q25, representing an 11% increase compared to 4Q24. Accumulative distribution margin as of December 2025 totaled ARS 1,253,262 million (+9% vs. 12M24). This was mainly driven by tariff increases (3.1% average monthly) and higher demand. Net Financial Results: During the year, financial results decreased by 38%, reaching ARS 377,238 million, mainly driven by a reduction in outstanding debt and lower interest expenses related to CAMMESA. Fourth quarter financial results rose, reaching ARS 61,445 million in 4Q25 (+50% vs. 4Q24). Net Results: For 4Q25, a profit of ARS 45,675 million was recorded, compared to a loss of ARS 21,399 million in 4Q24. The main reasons for the difference are the positive impact of the tariff adjustment and the increase in RECPAM. Investments: For4Q25, capex was ARS 103,415 millionwith an accumulative total of ARS 394,892 million. 8 EDENOR invested ARS 394,892 in 2025 and achieved improvements in main operating indicators. IMPROVEMENT IN RESULTS. EARNINGS RELEASE FOURTH QUARTER 2025 9 *4Q25: 876,768 customersbenefitedfromSocial Tariff Sales volumes in 4Q25 totaled 5,379 GWh, (+3.94% vs. 4Q24) mainly due to the effect on demand from residential and small commercial clients. Edenor's client base reached 3.39 million (+1% vs 4Q24), which was mainly due to an increase in the number of residential and medium-size commercial clients. With the continuation of our efforts to improve market discipline, a total of 3,729 energy meters were installed in the fourth quarter of 2025, which were largely designed to convert informal, unreported connections into fully transparent connections in the electricity distribution system. During 2025 8,156 smart meters were installed in all T3 clients.

This was mainly driven by optimization and efficiency improvements in the use of materials and inventory (-81%), a 23% reduction in professional fees, and lower depreciation of right-of-use assets. On a cumulative basis, during 2025 salaries and social security expenses decreased by 6%, reflecting the implementation of a development and retirement plan aimed at promoting talent renewal. At the end of December 2025, collectability was 95.75%, resulting in a period-end accrued bad debt of ARS 95,395 million.

These levels are the lowest observed since 2017 and are below the Regulator’s requirements. This recovery in service is mainly due to the strong investments that the Company has made over the last year. These investments have been focused on implementing improvements in operational processes and the adoption of technology applied to the operation and management of the network. QUALITY STANDARDS Note: SAIDI: Measures the number of hours a user is without service per year | SAIFI: Measures the number of times a user is without service per year. Requested Real EARNINGS RELEASE FOURTH QUARTER 2025 15 Driving Innovation and Efficiency in Loss Mitigation: We continue to leverage the potential of analytical and artificial intelligence tools, strategically optimizing inspection routes and raising their efficacy. The mission of DIME (“market discipline”) actions remains resolute: identifying and rectifying irregular connections, thwarting fraud, and curbing energy pilferage. Measurable Strides in Inspection and Detection: From October to December 2025, a substantial total of 66,822 inspections were conducted on Tariff 1 (Residential and General users), which showed an efficiency rate of 46.3%. This stands in comparison to the same period in the prior year when 130,635 inspections yielded an efficiency rate of 43.0%. Recovery Initiatives and Redefining Balance: To the inspections of MIDE and conventional meters was added the normalization of inactive accounts (that had been cancelled after the delinquency process had been exhausted) with MIDE meters. Progress is being made in the implementation of a system that fully and efficiently integrates the growing number of country clubs and closed neighborhoods. Despite our consistent efforts, cases of repeat fraud have continued. Energy losses LTM at December2025 were15.7%.
