The AGESP PN, which will be held, on first call, on November 17, 2025, is part of the measures necessary to complete the processes of changing its shareholding structure and migrating the Company to the Novo Mercado of [B]³ S.A. - Brasil, Bolsa, Balcão, as approved at the 212th Extraordinary General Meeting (AGE) on August 22, 2025. The other conditions set forth for the conversion, as approved at the 212th AGE, are following the common procedures for this type of operation and will be disclosed to the market in due course. In this regard, the Company emphasizes that the process of implementing the mandatory conversion of all class "B" preferred shares ("PNB") into class "A" preferred shares ("PNA") ("PN Unification") will be completed before the PN AGESP. Thus, prior to the date of the PN EGM, all shareholders currently holding preferred shares will be holders of PNA shares and will be able to vote on the PN Ratification. The Company will disclose a new Material Fact informing the dates related to the completion of the PN Unification, including the date on which the current PNB shareholders will have their respective PNA shares credited. The Company further emphasizes that holders of preferred shares who do not vote in favor of the PN Ratification at the PN AGESP will have the right to withdraw upon reimbursement of shares that they have held uninterruptedly between June 23, 2025, inclusive, and the effective date of reimbursement, as disclosed by the Company in due course. The documentation convening the PN AGM is available for consultation on the websites of the CVM (www.gov.br/cvm), [B]³ (www.b3.com.br), and the Company itself (https://ri.copel.com/). Reaffirming its commitment to transparency, in accordance with applicable laws and regulations and in line with best corporate governance practices, the Company reiterates that it will keep its shareholders and the market in general informed of relevant developments and progress through its usual disclosure channels.
