INTRODUCTION Copel’s Dividend Policy defines the guidelines and criteria for the distribution of dividends and its indebtedness. This Policy was prepared based on a meticulous analysis aimed at balancing factors such as shareholder compensation, maintaining the Company’s financial stability, and supporting long-term growth. Accordingly, Copel has established this Policy in compliance with its Bylaws, applicable regulations and legislation, and best practices of corporate governance. 1.1 - SCOPE To set out the guidelines and criteria for distribution of dividends and/or interest on equity (IOE) to Copel shareholders (Proceeds), with the aim of making the financial flow more transparent and predictable to shareholders, in accordance with the guidelines of the Company’s capital structure. Accordingly, it also establishes the payment frequency, distribution methods and the financial conditions that may change them. 1.2 - CONCEPTS The terms used in this Policy are conceptualized and organized in the Concept Book which can be accessed on the Copel Investor Relations website. 1.3 - PURPOSE The purpose of this policy is to set out the guidelines for the distribution of proceeds applicable to Companhia Paranaense de Energia - Copel (Holding). It seeks to maximize shareholder value and provide predictability through clear guidelines on how the Company will distribute its profits to shareholders, balancing the imperative to compensate investors and the need to reinvest in the business to sustain or accelerate growth. The aim is to provide adequate financial return to shareholders, compensating them for investment in the Company, while enabling financial sustainability and supporting longterm growth. 1.4 - PRINCIPLES To ensure that the distribution of profits to shareholders is balanced and sustainable, valuing shareholder return and financial soundness, meeting the Company’s cash flow needs and investment opportunities, always in legal and regulatory compliance and in line with the Company’s commitment to transparency. 1.5 - ASSUMPTIONS Key assumptions are as follows: a) Sustainability: Proceeds are supported by the Company’s consistent results; b) Reinvestment: Part of the profits may be allocated to reserves or withheld to fund expansion or innovation projects or to strengthen the financial structure; c) Maintaining solvency and liquidity: maintain appropriate cash and working capital levels to honor financial commitments and maintain a sound operation; d) Governance: compliance with legislation and Bylaws; e) Growth: compliance with the Copel Growth and Investment Policy; and f) Extraneous factors: analysis of macroeconomic and industry conditions. 1.6 - GUIDELINES 1.6.1 - Each year, management bodies shall present a proposal for the distribution of net profit for the fiscal year, if any, drawn up in accordance with applicable legislation and standards and with the parameters established in this Policy, to the General Meeting for deliberation. 1.6.2 - The proposal for the distribution of Proceeds should consider, in addition to the Company’s financial results and conditions, Intermediate and Interim Proceeds distributed, future prospects of the operating markets, investment strategies, financial covenants and other factors deemed relevant.
