REPORT ON REVIEW OF INTERIM FINANCIAL INFORMATION

To the Shareholders and Management of

Neoenergia S.A.

Introduction

We have reviewed the accompanying individual and consolidated interim financial information of Neoenergia S.A. ("Company"), included in the Interim Financial Information Form (ITR) for the quarter ended March 31, 2024, which comprises the statement of financial position as of March 31, 2024 and the related statements of income, of comprehensive income, of changes in shareholders' equity and of cash flows for the three-month period then ended, including the explanatory notes.

The Company's Management is responsible for the preparation of this individual and consolidated interim financial information in accordance with technical pronouncement CPC 21 (R1) and international standard IAS 34 - Interim Financial Reporting, issued by the International Accounting Standards Board - IASB, as well as for the presentation of such information in accordance with the standards issued by the Brazilian Securities and Exchange Commission (CVM), applicable to the preparation of Interim Financial Information (ITR). Our responsibility is to express a conclusion on this interim financial information based on our review.

Scope of review

We conducted our review in accordance with Brazilian and international standards on review of interim financial information (NBC TR 2410 and ISRE 2410 ‐ Review of Interim Financial Information Performed by the Independent Auditor of the Entity, respectively). 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 the 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.

Conclusion on the individual and consolidated interim financial information

Based on our review, nothing has come to our attention that causes us to believe that the accompanying individual and consolidated interim financial information included in the ITR referred to above was not prepared, in all material respects, in accordance with technical pronouncement CPC 21 (R1) and international standard IAS 34, applicable to the preparation of ITR, and presented in accordance with the standards issued by the CVM.

Statements of added value

The interim financial information referred to above includes the individual and consolidated statements of added value (DVA) for the three-month period ended March 31, 2024, prepared under the responsibility of the Company's Management and presented as supplemental information for international standard IAS 34 purposes. These statements were subject to the review procedures performed together with the review of the ITR to reach a conclusion on whether they are reconciled with the interim financial information and the accounting records, as applicable, and if their form and content are consistent with the criteria set forth in technical pronouncement CPC 09 (R1) - Statement of Added Value. Based on our review, nothing has come to our attention that causes us to believe that these statements of added value were not prepared, in all material respects, in accordance with technical pronouncement CPC 09 (R1) and consistently with the accompanying individual and consolidated interim financial information taken as a whole.

(1) Considers Construction Revenue
(2) Considers Construction Costs

As expressed in Technical Guidance OCPC 08, the recognition and measurement of variations between non-manageable costs actually incurred in relation to approved tariffs are always classified in the Operating Revenue line as Amounts Receivable/Returnable from Parcel A and Other Financial Items. Considering that a large part of Parcel A is recorded as energy costs, the isolated analysis of revenue and cost variations can lead to distortions in the interpretation of the results for the period. Therefore, the Company believes it is more appropriate to explain the variations in results based on the Gross Margin.

Neoenergia ended the 1Q24 with Gross Margin without VNR of R$ 4,239 million (+3% vs. 1Q23), impacted by the effects of: (i) increase in the customer base, (ii) higher volumes; (iii) Tariff Revisions for Neoenergia Coelba and Neoenergia Cosern in April 2023, variation in parcel B +2.5% and +0.25%, respectively; (iv) Neoenergia Brasília's 2023 Tariff Adjustment, effective from October/23 (variation in parcel B: +7.14%); (v) better result of Termopernambuco, and (vi) consolidation of Dardanelos from September 2023. These effects were mitigated by the lower Transmission margin, due to the non-consolidation of the 8 assets of the operation with GIC, which started to be accounted for as equity income from the 4Q23 and wind, due to lower generation, in addition to the Neoenergia Elektro Tariff Review in August 2023, with a variation in parcel B of -3.9% and the Neoenergia Pernambuco Tariff Adjustment in May 2023, which did not show variation in parcel B. The gross margin was R$ 4,657 million in the 1Q24 (-2% vs. 1Q23). It is worth remembering that in the 1Q23 VNR was positively impacted by a one-off of R$ 105 million at Neoenergia Coelba and R$ 40 million at Neoenergia Cosern connected with tariff reviews.

Operating expenses totaled R$ 1,033 million in the 1Q24 (+6% vs. 1Q23). Normalizing new assets and corporate operations, expenses grew by 4.6% vs. 1Q23, confirming cost discipline.

PECLD was R$ 158 million in the 1Q24, 10% lower than in the 1Q23, due to better collection performance.

Under Equity Income/Corporate Operations, in the 1Q24, R$ 41 million were recorded, of which R$ 37 million referred to the equity income of transmission assets in partnership with GIC and R$ 4 million to the result of the Corumbá plant through equivalence.

The Networks business ended the 1Q24 with Gross Margin without VNR of R$ 3,698 million (+3% vs. 1Q23), impacted by the effects of: (i) increase in the customer base, (ii) higher volumes; (iii) Tariff Reviews for Neoenergia Coelba and Neoenergia Cosern in April 2023, variation in parcel B +2.5% and +0.25%, respectively; and, (iv) Neoenergia Brasília's 2023 Tariff Adjustment, effective from October/23 (variation in parcel B: +7.14%). These effects were mitigated by the lower Transmission margin, due to the non-consolidation of assets in partnership with GIC, which began to be recorded as equity income from the 4Q23, in addition to the Neoenergia Elektro Tariff Review in August 2023, with variation in parcel B of -3.9% and the Neoenergia Pernambuco Tariff Adjustment in May 2023, which did not present a variation in parcel B. The gross margin was R$ 4,116 million in the 1Q24 (-3% vs. 1Q23). It is worth remembering that in the 1Q23 VNR was positively impacted by a one-off of R$ 105 million at Neoenergia Coelba and R$ 40 million at Neoenergia Cosern in the 1Q23 related to tariff reviews.

Operating expenses totaled R$ 844 million in the 1Q24 (+4% vs. 1Q23), absorbing inflation and an increase in the number of customers. Excluding new assets, expenses grew +3.0% vs. 1Q23.

PECLD was R$ 158 million in the 1Q24 (-10% vs. 1Q23) due to the intensification of disconnection and collection actions, which reflected in higher collections.

The Equity Income/Corporate Operations item in the 1Q24 was R$ 37 million referring to the equity income of transmission assets in partnership with GIC, which began to be accounted for under this item as of 4Q23.

As a result of the effects presented, EBITDA was R$ 3,151 million in the 1Q24 (-3% vs. 1Q23). Adjusted EBITDA, without VNR and IFRS, was R$ 2,464 million in the 1Q24 (+10% vs. 1Q23).
