Tariff overhaul lifts Edenor (NYSE: EDN) to 4Q25 profit and EBITDA surge

Rhea-AI Filing Summary

Empresa Distribuidora y Comercializadora Norte S.A. (edenor) reported a strong turnaround for 4Q25 and full-year 2025, helped by tariff normalization and cost control. Fourth-quarter revenues reached ARS 706,123 million, up 4% in constant currency versus 4Q24, driven mainly by a 319.2% tariff adjustment applied in February 2024 and average monthly increases of 3.1% since August 2024.

The company recorded a 4Q25 profit of ARS 45,675 million, compared with a loss of ARS 21,399 million in 4Q24, supported by higher distribution margin and inflation-adjustment effects (RECPAM). For 12M25, revenues rose to ARS 2,990,891 million from ARS 2,687,708 million, while EBITDA climbed to ARS 571,975 million, up 110% year over year, including an ARS 218 billion gain from a regularization agreement with CAMMESA.

Operating expenses in 4Q25 fell 6% to ARS 283,354 million as edenor optimized materials, reduced professional fees, and implemented a development and retirement plan that lowered salaries and social security costs by 6% for the year. Investments totaled ARS 394,892 million in 2025, with ARS 103,415 million in 4Q25, supporting better service quality: SAIDI fell to 6.81 hours and SAIFI to 2.96 outages per customer, improvements of 75% and 67% versus 2017, both below regulatory limits.

Insights

Equity analyst – Latin American utilities

Tariff reset and cost discipline drove edenor’s 2025 earnings recovery and stronger balance sheet.

edenor shows a marked financial rebound after Argentina’s 5-year tariff review. 12M25 revenues rose to ARS 2,990,891 million, while EBITDA reached ARS 571,975 million, up 110% year over year, aided by the tariff step-up and a CAMMESA regularization gain of ARS 218 billion.

Fourth-quarter profitability also improved sharply: 4Q25 revenues were ARS 706,123 million, distribution margin grew 11% versus 4Q24, and the company moved from a 4Q24 loss to a 4Q25 profit of ARS 45,675 million. Operating expenses declined 6% in 4Q25 as management cut materials usage, professional fees and personnel costs.

Leverage remains relevant but better framed. Total financial debt was USD 782M with net debt of USD 657M as of December 30, 2025, while service quality indicators SAIDI and SAIFI improved 75% and 67% versus 2017. Actual long-term impact will depend on consistent tariff indexation, ongoing investment execution and future regulatory decisions on the “regulatory asset” claim.

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.

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.

These levels are the lowest observed since 2017 and are below the Regulator’s requirements.

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%.
