The completion of the transaction is subject to the approval of the EGM and the obtaining of the required authorizations from ANEEL. Lastly, the Company notes that additional information on the mergers and the EGM is available for consultation in the call documents disclosed on this date on the websites of the Company (https://ri.axia.com.br/en/), the CVM (https://www.gov.br/cvm/en), and B3 (https://www.b3.com.br/en_us/).

Description and purpose of the transaction By means of the Mergers, AXIA Energia seeks to simplify its corporate structure, promoting the consolidation of the operational, administrative, and tax activities currently carried out by the Merged Companies, which will be extinguished. The Mergers will also contribute to the strengthening of corporate governance, insofar as these activities will begin to be carried out directly by the Company. The Mergers will be carried out pursuant to Articles 224 through 227 of Law No. 6,404/1976 (“Brazilian Corporations Law”), resulting in the extinction of the Merged Companies and the succession, by AXIA Energia, to all of their rights and obligations. AXIA Energia S.A. 00.001.180/0001-26 Avenida Graça Aranha, 26 – Centro Rio de Janeiro │RJ – Brasil │20030-900 The consummation of the Mergers is subject to the verification of the conditions precedent set forth in the respective protocol and justification instruments executed between the managements of AXIA Energia and the Merged Companies, including the obtaining of the required authorizations from ANEEL. 3. Main benefits, costs, and risks of the transaction 3.1. Benefits of the Mergers. The Mergers will allow: (i) to simplify the corporate structure of the AXIA Energia group, with the restructuring and consolidation of operational, administrative, and tax activities; (ii) higher levels of corporate governance with respect to the activities previously carried out by the Merged Companies, since such activities will begin to be carried out directly by AXIA Energia; and (iii) greater speed in the decision-making processes, which will be carried out directly by AXIA Energia. 3.2. Costs of the Mergers It is estimated that the total costs and expenses related to the completion and consummation of the Mergers, considering the fees of legal advisors and appraisers, will total the approximate amount of R$ 340,000.00, without considering ordinary costs of registration and publication of corporate acts. After the consummation of the Mergers, it is further estimated that there will be cost reductions for the AXIA Energia group arising, in particular, from the elimination of redundancies and inefficiencies, as well as from the more efficient allocation of resources and people. 3.3. Risks of the Mergers Considering that the Merged Companies are wholly held, directly and indirectly, by the Company, there is no change in the Company’s risk exposure as a result of the Mergers. 4. Exchange ratio of the shares AXIA Energia S.A. 00.001.180/0001-26 Avenida Graça Aranha, 26 – Centro Rio de Janeiro │RJ – Brasil │20030-900 Not applicable, considering that the shares of all the Merged Companies are already directly or indirectly held by AXIA Energia. 5. Criterion for setting the exchange ratio Not applicable, considering that, pursuant to item 4 above, there will be no exchange ratio. 6. Main asset and liability elements that will form each portion of the equity, in the event of a spin-off Not applicable, since no spin-off will occur. 7. Whether the transaction was or will be submitted to the approval of Brazilian or foreign authorities All the Mergers are subject to the obtaining of the required authorizations from ANEEL for the transfer of ownership of the relevant concessions. The Mergers will not be submitted to the approval of other authorities, Brazilian or foreign. 8. In transactions involving controlling companies, controlled companies, or companies under common control, the exchange ratio of shares calculated in accordance with Article 264 of Law No. 6,404, of 1976 Not applicable, given that: (i) the Mergers will be carried out without an exchange ratio of the shares; and (ii) there are no non-controlling shareholders in the Merged Companies to be protected. 9. Applicability of the withdrawal right and reimbursement value There will be no withdrawal right as a result of the Mergers. The withdrawal right, in merger transactions, is ensured to the dissenting shareholders of the merged company, pursuant to Articles 137 and 230, in conjunction with Article 136, item IV, of the Brazilian Corporations Law. In this case, considering that AXIA Energia is the sole direct and indirect shareholder of the Merged Companies, there will be no dissenting shareholder able to exercise the withdrawal right.
