(a) Effects mainly of business combinations occurring in 2023. 12.1.1. Projection for realization of deferred income tax and social contribution: The projection of deferred tax credits realization recorded in noncurrent assets and liabilities is based on the realization period of each item of deferred assets and liabilities and tax losses, according to future results projections. The criteria used for the realization of each item are related to the predictability of realization of the main value that gave rise to the temporary difference. When the expectation of realization of the item is difficult to predict, mainly because it is not under the control of the Company, such as provisions for legal claims, the Company adopts history of realization to project its future realization. Following are the items that were the basis for the setup of the main credits of the company, as well as their form of realization: •Provision for allocation of PIS and Cofins credits: will be carried out as the amounts are passed on in the tariff review and readjustment processes approved by the regulatory body, if any, or by the reversal of the respective provision; •Provisions for post-employment benefits: realized as the payments are made to the Copel Foundation or reversed according to new actuarial estimates; •Provisions for legal claims: realized according to court decisions or by the reversal when the possible risk of the shares is reviewed; •Impairment of assets: realized through the amortization and/or depreciation of the impaired asset; •Deemed cost: realized to the extent that the amortization, depreciation, write-off or disposal of the valued asset occurs; •Amounts related to the concession agreement: realized over the term of the agreement; •Amounts related to tax losses and negative tax basis: recovered by offsetting against future taxable income, considering the limit established in the legislation; and •Other amounts: realized when they meet the deductibility criteria provided for in tax legislation, or upon reversal of the recorded amounts. The projected realization of the deferred taxes is shown below:

12.1.2. Unrecognized tax credits In addition to the deferred income tax and social contribution credits recorded in assets, on December 31, 2024, the Company did not recognize income tax and social contribution credits on income tax and social contribution tax losses in the amount of R$105,311 (R$87,410, as of December 31, 2023) for not having reasonable assurance of generation of future taxable profits sufficient to allow the utilization of these tax credits, mainly at Cutia Empreendimentos Eólicos S.A. (subsidiary of Copel GeT). 12.2. Other taxes recoverable and other tax obligations

Asset and liability balances presented on a net basis, considering the Company's right and intention to realize the asset and liability on a net basis. (a) The balance contains amounts referring Pis and Cofins credit on ICMS (Notes 12.3) (b) Installment of ICMS tax credits from the State of Paraná, with payment deadline until September 2027. (c) In March 2024, after the disputes were concluded, the balances were written off against the judicial deposit balance recorded in assets (Note 13) 12.3. Pis and Cofins credit on ICMS - Copel Distribuição Balance resulting from the final and unappealable decision in June 2020 regarding the lawsuit filed by Copel DIS in 2009, which recognized the right to exclude from the PIS and Cofins tax base the full amount of ICMS included in the energy supply and distribution invoices and recognized that the limitation period, in this case, is of five years and that, therefore, Copel DIS has the right to recover the amounts that have been paid during the five years preceding the filing of the writ of mandamus until the date of the final unappealable decision, therefore from August 2004 to June 2020. The updated tax credit in assets, after the credits were enabled by the Brazilian Federal Revenue Service, has been recovered through compensation with taxes payable since June 2021, for the Cofins credit and since January 2024 for PIS credit. The following table shows the movement of the asset:
Balance as of January 1, 2023 | 3,484,616 |

Balance as of December 31, 2024 | 1,723,027 |
Current | 804,084 |
Noncurrent | 918,943 |
The asset will continue to be offset against future federal tax debts, respecting the deadlines and limits established by current tax legislation. 12.3.1. Pis and Cofins to be refunded to consumers and Provision for allocation of PIS and Cofins credits In June 2020, Copel DIS recorded PIS and Cofins liability to be refunded to consumers related to the recovery of tax credits for the last 10 years, counting from the date of the final and unappealable decision of the lawsuit filed by the Company, considering the current legislation, the statute of limitations period defined in the civil code and the jurisprudence of the courts. In June 2022, arising from the effects of Federal Law No. 14,385/2022, Copel DIS, listening to the opinion of its external legal advisors and based on the risk assessment, recognized a provision for the allocation of PIS and Cofins credits referring to the period between the 11th and the 16th year from the date of the final and unappealable decision of the lawsuit, therefore from 2004 to 2010. The amounts have been refunded to consumers, through the tariff process, as the tax credits in the assets are offset. On June 24, 2024, Aneel Homologation Resolution 3,336/2024 determined the refund to the consumer of the amount of R$1,182,915, with a reducing effect on the tariff during the 2024-2025 tariff cycle. Thus, the remaining balance of the liability was used to refund consumers and the difference was written off from the provision for allocation of PIS and Cofins credits. The table below illustrates the changes in liabilities and provisions:
| Liabilities to be refunded to consumers | Provision for allocation of PIS and Cofins credits | Total
Balance as of January 1, 2023 | 1,995,158 |  | 1,851,257 |  | 3,846,415 |

Regarding the provision for the controversial period, the Company is evaluating the appropriate measures to be taken, including legal measures, considering the shelter given to unappealable decisions and applicable limitation periods. Concomitantly, on December 12, 2022, the Brazilian Association of Electric Energy Distributors - Abradee filed a Direct Action of Unconstitutionality - “ADI” with the Federal Supreme Court - “STF”, questioning Law No. 14,385/2022. On September 4, 2024, the ministers formed a majority in favor of the constitutionality of the law. However, regarding the limitation period for the collection of amounts from consumers, so far five ministers voted for the application of the ten-year term (10 years), in line with the understanding of Copel Management, and two ministers voted for the application of the five-year term (5 years). The judgment is suspended due to the request for review by Minister Luis Roberto Barroso. The Company is awaiting the judgment's finalization. 12.4.

With regard to uncertainties about the treatment of income taxes, the Company has made assessments and concluded that it is more likely than not that the treatments will be accepted by the tax authority. 12.5. Consumption tax reform In December 2023, Constitutional Amendment No. 132 was enacted, establishing the Tax Reform in the field of consumption.The new model adopts a split Value Added Tax system ("dual VAT") with two competencies: a federal one (Contribution on Goods and Services - “CBS”) which will replace PIS and Cofins, and a sub-national one (Tax on Goods and Services - “IBS”) which will replace ICMS and ISS. Additionally, a federal Selective Tax (“IS”) was created, which will be applied to the production, extraction, sale or import of goods and services that are detrimental to health and the environment, as defined by the complementary legislation. On January 16, 2025, Complementary Law - LC No. 214 was sanctioned, regulating part of the tax reform. The Federal Senate is still analyzing Complementary Bill No. 108/2024, which will finalize the regulations. The Reform establishes a transition period from 2026 to 2032 during which the current and new tax systems will coexist. In the electricity sector, LC No. 214 stipulates the deferral of taxation of CBS and IBS throughout the production chain, ensuring that taxation will only occur in the operation with the final consumer. This measure should significantly reduce the impact of the reform on the sector. In addition, given the express provisions in the law and in the concession contracts regarding financial economic rebalancing for public service concessions, the company anticipates that the impacts of the reform will be reduced for its business. Regarding IS, given the company's renewable energy matrix, no significant impacts are expected. However, the full effects of the tax reform on the calculation of the aforementioned taxes will only be known once the pending issues have been regulated by complementary law and the reference rate has been defined. Therefore, there is no impact of the tax reform on the financial statements as of December 31, 2024.
