Copel (ELP) adopts updated bylaws on voting caps and control rules

Q: What special rights does the State of Paraná have in Copel (ELP) under the new bylaws?

The State of Paraná holds a special class preferred share that gives it priority in capital reimbursement on liquidation, and a veto power over specific shareholders’ meeting resolutions. These include attempts to change the corporate name, move the headquarters out of Paraná, alter the 10% voting cap, allow certain shareholders’ agreements, or change rules that tie Copel Distribuição S.A.’s annual investment plan to at least 2.0 times the Regulatory Reintegration Quota (QRR) in the 2021/2025 rate cycle and beyond.

Q: What are the voting limits for Copel (ELP) shareholders set by the bylaws?

The bylaws state that no shareholder or group of shareholders , whether Brazilian or foreign, public or private, may exercise voting rights in excess of 10% of the total voting share capital , regardless of their ownership stake. Shareholder agreements that regulate voting rights above this 10% threshold are prohibited, and the chair of the General Shareholders’ Meeting must disregard votes cast in violation of these limits.

Q: What change-of-control and public tender offer rules apply to Copel (ELP) under these bylaws?

The bylaws require that any direct or indirect transfer of control be conditioned on the acquirer launching a public tender offer for the shares held by other shareholders, following Brazilian law and Novo Mercado rules, to ensure equal treatment. Separately, any shareholder or group that acquires more than 25% of voting capital must offer to buy all remaining common shares at a price at least 100% higher than the highest trading price in the previous 504 trading sessions, and if they pass 50% , the minimum offer price must be at least 200% higher , both adjusted by the SELIC rate.

Q: How is corporate governance structured at Copel (ELP) according to the updated bylaws?

The bylaws establish a governance structure with a Board of Directors of 7–9 members serving unified two-year terms, a separate Executive Board led by a President and Vice Presidents, and non-permanent Supervisory Board if installed. They also create four statutory committees —Audit, Investment and Innovation, Sustainable Development, and People—to advise the Board of Directors on financial oversight, capital allocation, ESG issues and human resources, each under specific internal regulations approved by the Board.

Rhea-AI Filing Summary

Companhia Paranaense de Energia (Copel) reports updated bylaws approved at its 212th Extraordinary General Meeting of Shareholders. The bylaws set the corporate purpose around researching, producing, transporting, distributing and trading energy, and related infrastructure and telecommunications activities, in Brazil and abroad. Share capital is described as R$12,831,618,938.25, divided into 2,982,810,590 common book-entry shares and 1 special class preferred share held by the State of Paraná.

The new text details governance rules, including a Board of Directors with 7–9 members serving two-year unified terms, a separate Executive Board, and statutory committees for audit, investment and innovation, sustainable development and people. Voting rights are capped so no shareholder or group may exercise more than 10% of voting capital, and shareholder agreements that exceed this limit are prohibited. The State of Paraná’s special preferred share grants veto power over specified matters, such as changes to the corporate name, headquarters location, voting caps, and minimum investment levels for the distribution subsidiary.

The bylaws also define dividend and interest-on-equity distribution of at least 25% of adjusted net income, conditions for capital increases up to 4,000,000,000 shares, rules for related-party approvals, and use of indemnity, insurance and legal defense for managers. They incorporate Novo Mercado requirements, including public tender offers in change-of-control situations and mandatory offers at premium prices if a shareholder or group surpasses 25% or 50% of voting capital, and adopt mandatory arbitration at the Market Arbitration Chamber for corporate disputes.

FAQ

What did Copel (ELP) disclose in this Form 6-K?

Copel disclosed a fully updated and consolidated version of its bylaws, as approved by the 212th Extraordinary General Meeting of Shareholders held on 08/22/2025. The document sets out the company’s corporate purpose, capital structure, governance framework, voting limits, dividend rules, defense mechanisms and procedures for change of control and exit from B3’s Novo Mercado segment.

How much share capital and how many shares does Copel (ELP) have under the bylaws?

The bylaws state that Copel’s fully paid-in share capital is R$12,831,618,938.25, divided into 2,982,810,590 common, nominative, book-entry shares without par value and 1 special class preferred share held exclusively by the State of Paraná.

What special rights does the State of Paraná have in Copel (ELP) under the new bylaws?

The State of Paraná holds a special class preferred share that gives it priority in capital reimbursement on liquidation, and a veto power over specific shareholders’ meeting resolutions. These include attempts to change the corporate name, move the headquarters out of Paraná, alter the 10% voting cap, allow certain shareholders’ agreements, or change rules that tie Copel Distribuição S.A.’s annual investment plan to at least 2.0 times the Regulatory Reintegration Quota (QRR) in the 2021/2025 rate cycle and beyond.

What are the voting limits for Copel (ELP) shareholders set by the bylaws?

The bylaws state that no shareholder or group of shareholders, whether Brazilian or foreign, public or private, may exercise voting rights in excess of 10% of the total voting share capital, regardless of their ownership stake. Shareholder agreements that regulate voting rights above this 10% threshold are prohibited, and the chair of the General Shareholders’ Meeting must disregard votes cast in violation of these limits.

How do the Copel (ELP) bylaws address dividends and profit distribution?

The bylaws provide that shareholders are entitled each fiscal year to receive dividends and/or interest on equity of at least 25% of adjusted net income, calculated under Federal Law No. 6,404/1976. The Board of Directors may authorize interim and interim-dividend distributions or interest on equity based on annual or interim financial statements, with amounts credited against the mandatory dividend, and profits can be allocated to legal and other reserves within legal limits.

What change-of-control and public tender offer rules apply to Copel (ELP) under these bylaws?

The bylaws require that any direct or indirect transfer of control be conditioned on the acquirer launching a public tender offer for the shares held by other shareholders, following Brazilian law and Novo Mercado rules, to ensure equal treatment. Separately, any shareholder or group that acquires more than 25% of voting capital must offer to buy all remaining common shares at a price at least 100% higher than the highest trading price in the previous 504 trading sessions, and if they pass 50%, the minimum offer price must be at least 200% higher, both adjusted by the SELIC rate.

How is corporate governance structured at Copel (ELP) according to the updated bylaws?

The bylaws establish a governance structure with a Board of Directors of 7–9 members serving unified two-year terms, a separate Executive Board led by a President and Vice Presidents, and non-permanent Supervisory Board if installed. They also create four statutory committees—Audit, Investment and Innovation, Sustainable Development, and People—to advise the Board of Directors on financial oversight, capital allocation, ESG issues and human resources, each under specific internal regulations approved by the Board.
