Optimal Capital Structure and New Dividend Policy

COPEL (“Company”) hereby informs its shareholders and the market in general that its wholly-owned subsidiary Copel Geração e Transmissão S.A. (“Copel GeT”) has approved, on May 08, 2025, the Company's optimal capital structure and a new Dividend Policy ("New Policy"), which aims to reinforce a balanced and sustainable profit distribution, valuing shareholder returns, financial solidity, meeting cash needs and investment opportunities for the Company.

COPEL has defined that its optimal capital structure considers the following factors:

• Financial leverage is 2.8x, measured by net debt/EBITDA; and

• A tolerance range of 0.3X up (3.1x) or down (2.5x) as long as there is convergence within 24 months to the center of the range (2.8X).

The New Dividend Policy will provide more transparency and predictability of the dividend payment flow to the Company shareholders. In this regard, the annual amount of dividends will consider the following financial parameters determined at the end of each fiscal year:

• The financial leverage defined for the Company's optimal capital structure;

• Minimum of 75% of Net Profit; and

• Minimum payment frequency of 2 times a year.

For more details, access the full New Policy on the investor relations website (ri.copel.com).
