 Centrais Elétricas Brasileira S/A 00.001.180/0001-26 Avenida Graça Aranha, 26 – Centro Rio de Janeiro │RJ – Brasil │20030-900 Colíder Hydroelectric Power Plant leaves alert status Rio de Janeiro, February 23 , 2026 – Centrais Elétricas Brasileiras S/A – Eletrobras (“Company” and “AXIA Energia”), further to the market announcement dated August 15, 2025, informs that the Colíder Hydroelectric Power Plant has officially exited alert status and returned to attention status, after technical analyses confirmed that the interventions carried out were effective in resolving the condition that had led to the alert. The Company will begin today the gradual and controlled refilling of the reservoir, prioritizing the safety of people and the environment. The process includes continuous monitoring of water quality and wildlife, as well as communication with local communities. The procedure was authorized by the competent authorities following the review of the respective action plan. Background In order of increasing severity, the four possible safety levels are classified as normal, attention, alert, and emergency. In May 2025, AXIA Energia acquired the power plant from Companhia Paranaense de Energia — Copel while it was in attention status. At that time, the Company began implementing measures aimed at changing the safety level to normal, including a safety inspection conducted by AXIA Energia specialists and by an external Board of Consultants to define and implement an action plan to achieve this objective. In August 2025, following problems identified in some drainage systems, the facility moved from attention status to alert status. Since then, the Company has commissioned technical studies and specialists to further assess the structure. As a preventive measure, controlled drawdown of the reservoir was carried out, and field actions were implemented to prevent environmental and social impacts. The interventions recommended based on this diagnosis were executed and completed in November 2025, after which the Company began conducting additional tests and monitoring to assess the adequacy of the measures adopted. These measures proved effective, allowing the safety level to be changed from alert to attention. AXIA Energia will continue to carry out monitoring and complementary work with the objective of restoring the plant to normal safety status. These actions reinforce AXIA Energia’s priority on the safety of people, the environment, and its assets. Eduardo Haiama Vice President of Finance and Investor Relations
