Among other matters, the Board of Directors deliberated on: 01. PROPOSAL FOR A DECLARATION OF INTEREST ON EQUITY BASED ON RETETAINED EARNINGS - Mr. Felipe Gutterres Ramella, Vice President of Finance and Investor Relations, accompanied by his technical team, presented a proposal for distribution of earnings in the form of Interest on Equity in the gross amount of R$706,000,000.00 (seven hundred and six million reais) based on the Retained Earnings account, to be credited to shareholders holding shares as of April 29, 2026 (record date), subject to trades executed up to and including that date. Accordingly, as of April 30, 2026, inclusive, the Company's common shares will be traded "ex-dividend." The amounts of Interest on Equity, net of withholding taxes, will be allocated to the mandatory dividend for the 2026 fiscal year, in accordance with the criteria established in Article 84, Paragraph 2 of the Company's Bylaws. After analyzing and discussing the information provided, receiving the clarifications deemed necessary, and considering the favorable recommendation of the Executive Board, issued at its 2660th Meeting on April 9, 2026, the Board of Directors unanimously resolved to approve the proposal for the distribution of earnings in the form of Interest on Equity, as recorded in the material held by the Department of Secretariat and in accordance with item 1.8 of the Dividend Policy, with payment to be made on September 30, 2026, pursuant to Article 30, item XXII, and Article 84, paragraph 1, of the Company's Bylaws. ---------------------------------------------------------------- 02. FORM 20-F - Mr. Felipe Gutterres Ramella, Vice President of Finance and Investor Relations, accompanied by his team and with the support of the Integrity Office (DRC/SIN), presented Form 20-F to be filed with the Securities and Exchange Commission - SEC. He stated that this report contains accounting information for the fiscal year 2025, already approved by the Executive Board and the Board of Directors (Standardized Financial Statements - DFP). In addition, the document contains additional information for shareholders regarding: (i) risk factors, (ii) the Company, (iii) the electric power sector model, (iv) management (Executive Board and Boards), (v) dividend distribution, (vi) internal controls, among other information. Next, the members of the Statutory Audit Committee were heard; they reported having analyzed the matter at their 326th Meeting on April 14, 2026, and recommended its approval to this Board. After analyzing and discussing the COMPANHIA PARANAENSE DE ENERGIA - COPEL CNPJ No. 76.483.817/0001-20 PUBLIC COMPANY CVM Registration No. 1431-1 NIRE 41300036535 information provided, receiving the clarifications deemed necessary, and considering the favorable recommendation of the Executive Board, issued at its 2660th Meeting on April 9, 2026, as well as that of the Statutory Audit Committee, as noted above, the Board of Directors unanimously resolved to approve the 20-F Report as recorded in the material held by the Department of Secretariat. ------------------------------------------------ The other matters dealt with at this meeting have been omitted from this certificate, out of legitimate caution, supported by the Administration's duty of secrecy, in accordance with the caption of article 155 of Law no. 6.404/76, since they relate to interests that are merely internal to the Company, and therefore fall outside the scope of the rule contained in paragraph 1 of article 142 of the aforementioned Law.
