**Timelines for the Unification of Preferred Shares (PNB and PNA)**

**COMPANHIA PARANAENSE DE ENERGIA – COPEL** ("Company"), in continuity with Material Facts No. 4/25, 6/25, 7/25, 8/25, 9/25, and 11/25, and in compliance with paragraph 4 of Article 157 of Law No. 6,404, dated December 15, 1976 ("Lei das S.A."), and with the provisions of the Brazilian Securities and Exchange Commission ("CVM") Resolution No. 44, dated August 23, 2021, as amended, and considering that, as of this date, the Company has obtained the final consents ("Waivers") from creditors whose financial instruments provided for early maturity of the Company's or its subsidiaries' debts due to the approval of matters at the Extraordinary General Meeting held on August 22, 2025 ("EGM"), hereby informs its shareholders and the market in general that the schedule for the mandatory conversion of all Class "B" preferred shares ("PNB") into Class "A" preferred shares ("PNA") ("PN Unification") will follow the timeline below:

---

| | |
|:---|:---|
| &nbsp;&nbsp;**Date** | &nbsp;&nbsp;**Event / Note** |
| &nbsp;&nbsp;November 7, 2025 | &nbsp;&nbsp;Last trading day of PNB shares on the secondary market and execution of the PN Unification by B3 S.A. – Brasil, Bolsa, Balcão ("B3") and the Company's bookkeeping agent. |
| &nbsp;&nbsp;November 10, 2025 (inclusive) | &nbsp;&nbsp;PNB shares cease to be traded due to their conversion into PNA shares. |
| &nbsp;&nbsp;November 12, 2025 | &nbsp;&nbsp;Credit of PNA shares to former holders of PNB shares. |

---

Additionally, as a result of the PN Unification, beginning on November 10, 2025, American Depositary Shares currently representing PNB shares will automatically begin representing PNA shares (the "Preferred ADSs"). The CUSIP number and symbol of Preferred ADSs will not be impacted as a result of the PN Unification.

As previously disclosed in Material Fact No. 11/25, the PN Unification process will be completed prior to the special meeting of preferred shareholders ("AGESP PN"), which will be held, on first call, on November 17, 2025, as per the documentation previously made available on the websites of the CVM (www.gov.br/cvm), B3 (www.b3.com.br), and the Company itself (https://ri.copel.com/).

For clarification purposes, as indicated in the AGESP PN call documentation, current holders of PNA and PNB shares may duly complete remote voting ballots until the PN Unification is executed. These ballots will remain valid and will be duly counted for quorum purposes at the AGESP PN.

Accordingly, at the AGESP PN, all preferred shareholders will hold PNA shares and may resolve, pursuant to Article 136, paragraph 1, of the Brazilian Corporate Law, on the ratification ("PN Ratification") of the mandatory conversion of all preferred shares into one new common share and one new Class "C" preferred share ("PNC"), which will be mandatorily redeemable ("PN Conversion").

The Company reiterates that holders of preferred shares who do not approve the PN Conversion at the AGESP — whether by dissent, abstention, or absence — will be entitled to exercise withdrawal rights through the reimbursement of shares held continuously from June 23, 2025 (inclusive) until the effective reimbursement date, as will be timely disclosed by the Company.

Reaffirming its commitment to transparency, in compliance with applicable laws and regulations and aligned with best corporate governance practices, the Company emphasizes that it will keep its shareholders and the market informed of any relevant developments through its usual disclosure channels mentioned above.
