In continuity to what was presented at the 200th Extraordinary Board of Directors’ Meeting held on March 10. Mr. Adriano Rudek de Moura, Chief Financial and Investor Relations Officer, and Mr. Ronaldo Bosco Soares, Accounting Superintendent, presented the Board of Directors the Executive Board’s Proposal for the Allocation of Net Income for Fiscal Year 2020 and Payment of Profit Sharing Related to the Integration of Capital and Labor and Incentive to Productivity, as follows: THE EXECUTIVE BOARD’S PROPOSAL FOR THE ALLOCATION OF NET INCOME FOR THE FISCAL YEAR 2020 AND PAYMENT OF PROFIT SHARING RELATED TO THE INTEGRATION OF CAPITAL AND LABOR AND INCENTIVE TO PRODUCTIVITY: Mr. Chairman of the Board of Directors of Companhia Paranaense de Energia - Copel: In compliance with the provisions of article 192 of Law 6,404, dated December 15, 1976, and other legal and statutory provisions in force, we present this Board, for deliberation at the 66th Annual General Meeting, after hearing the Fiscal Council, the proposals set forth below. I. ALLOCATION OF NET INCOME: Of the net income for the 2020 fiscal year, calculated in accordance with corporate

law, in the amount of R$ 3,904,203,695.86 (three billion, nine hundred and four million, two hundred and three thousand, six hundred and ninety-five reais and eighty-six centavos), the Executive Board proposes the following: a) R$195,210,184.79 (one hundred and ninety-five million, two hundred and ten thousand, one hundred and eighty-four reais and seventy and nine centavos), corresponding to 5% of net income, as legal reserve, pursuant to article 193 of Law 6,404, of December 15, 1976, and article 87, paragraph 2, item II, of the Bylaws; b) R$807,500,000.00 (eight hundred and seven million and five hundred thousand reais) as interest on equity, as a partial replacement of the minimum mandatory dividends, pursuant to article 202 of Law 6,404, of December 15, 1976, article 9, paragraph 7, of Law 9,249, of December 26, 1995, and article 88 of the Company's Bylaws; c) R$781,331.33 (seven hundred and eighty-one thousand, three hundred and thirty-one reais and thirty-three centavos) as complementary dividends to shareholders of PNA shares, which were declared and paid, as decided at the 260th Board of Directors’ Meeting, held on September 16, 2020; d) R$210,275,576.76 (two hundred and ten million, two hundred and seventy-five thousand, five hundred and seventy-six reais and seventy-six centavos) as dividends in addition to the mandatory minimum amounts, pursuant to article 202 of Law 6,404, of December 15, 1976, article 9, paragraph 7, of Law 9,249, of December 26, 1995 and in article 88 of the Company’s Bylaws, as well as the rules established by CVM Resolution 683, of August 30, 2012, and by ICPC Technical Interpretation 08 (R1) of the Accounting Pronouncements Committee, which addresses the accounting of the proposed dividend payment; ·According to legal and statutory provisions in force, shareholders are entitled to receive dividends in an amount no less than 25% of the adjusted net income, calculated as net income for the year minus the amounts allocated for the legal reserve. However, the aforementioned calculation base was adjusted to the equity valuation according to item 28 of ICPC10, in such a way that it canceled the negative effect to the net income of the year caused by the increase in depreciation expenses, resulting from the adoption of the accounting standards established by said instruction, as well as Accounting Pronouncement CPC27 - Property, Plant and Equipment, which totaled, net of income tax and social contributions, R$59,628,859.28 (fifty-nine million, six hundred and twenty-eight thousand, eight hundred and fifty-nine reais and twenty-eight centavos) in 2020. Therefore, the amounts for the calculation base and the minimum mandatory dividends are R$3,768,622,370.35 (three billion, seven hundred and sixty-eight million, six hundred and twenty-two thousand, three hundred and seventy reais and thirty-five centavos) and R$942,155,592.59 (nine hundred and forty-two million, one hundred and fifty-five thousand, five hundred and ninety-two reais and fifty-nine centavos), respectively. ·CVM Resolution 683, August 30, 2012, approved and made mandatory, for publicly held companies, the application of Technical Interpretation ICPC 08 (R1), issued by the Accounting Pronouncements Committee (CPC), which establishes the accounting rules for proposed dividend payments. According to said legal basis, proposed interest on equity can only be included as minimum mandatory dividends at an amount that is net of withholding income tax, which is taxed at a 15% (fifteen percent) rate for this type of income. However, for interest on equity paid to exempt shareholders, there is no such incidence of withholding taxes. The amount of withholding taxes for shareholders who are subject to taxation, was R$76,401,315.50 (seventy-six million, four hundred and one thousand, three hundred and fifteen reais and fifty centavos), resulting in an effective tax rate of 9.46% (nine and forty-six hundredths percent) for the 2020 fiscal year. Therefore, the proposed interest on equity payable, in the gross amount of R$807,500,000.00 (eight hundred and seven million and five hundred thousand reais), will result in a net payment of R$731,098,684.50 (seven hundred and thirty-one million, ninety-eight thousand, six hundred and eighty-four reais and fifty centavos) to shareholders, of which, added to the R$781,331.33 (seven

hundred and eighty-one thousand, three hundred and thirty-one reais and thirty-three centavos), proposed as complementary dividends, declared and paid to the shareholders of PNA shares, and the R$210,275,576.76 (two hundred and ten million, two hundred and seventy-five thousand, five hundred and seventy-six reais and seventy-six centavos), proposed as complementary dividends to the mandatory minimum amounts, total remuneration, net of withholding tax, was R$942,155,592.59 (nine hundred and forty-two million, one hundred and fifty-five thousand, five hundred and ninety-two reais and fifty-nine centavos) corresponding to the minimum statutory dividends; e) R$2,750,065,462.26 (two billion, seven hundred and fifty million, sixty-five thousand, four hundred and sixty-two reais and twenty-six centavos) was for the constitution of profit retention reserve, which serves the purpose of ensuring the Company's investment program, as established in article 196 of Law 6,404, of December 15, 1976, and article 87, paragraph 2, item IV, of the Company’s Bylaws. ·The profit retention reserve corresponds to the sum of the remaining net income balance for the year, after the constitution of the legal reserve, after equity valuation adjustments and minus the proposed interest on equity and dividends to shareholders. Below is a statement of the changes that occurred in the “retained earnings” account, including the alllocation proposed herein: Equity changes: Net income for the 2020 fiscal year: R$3,904,203,695.86; ( - ) Legal reserve (5% of net income for the period): R$195,210,184.79; = Adjusted Net Income: R$3,708,993,511.07; ( + ) Equity valuation adjustments - net of taxes: R$59,628,859.28; = Calculation basis for mandatory minimum dividends: R$3,768,622,370.35; ( - ) Interest on equity - gross amount: R$807,500,000.00; ( - ) Complementary dividends (PNA shares): R$781,331.33; ( - ) Complementary dividends to the mandatory minimum: R$210,275,576.76; ( - ) Retained profits reserve: R$2,750,065,462.26. The financial statements for the year 2020 reflect the effects of the accounting records for the allocations previously specified, based on the assumption that they will be approved by the 66th Annual General Meeting, as established in article 176, paragraph 3, of Law 6,404, of December 15, 1976. I.1. PROFIT SHARING RELATED TO THE INTEGRATION OF CAPITAL AND LABOR AND INCENTIVE TO PRODUCTIVITY: Federal Law 10,101, of December 19, 2000, State Law 16,560, of September 8, 2010 and State Decree 1978, of December 20, 2007 regulates employee profit sharing in the Company's profits, as an integration instrument of capital and labor and as an incentive to productivity, pursuant to article 7, item XI, of the Federal Constitution. In compliance with the aforementioned legislation, the Executive Board proposes the distribution, as means of profit sharing, in the amount of R$420,004,161.37 (four hundred and twenty million, four thousand, one hundred and sixty-one reais and thirty-seven centavos) to be paid by the Parent Company and the wholly owned subsidiaries to their employees. Said profit sharing has been provisioned in the "personnel expenses" line of the financial statements for the 2020 fiscal year, in accordance with item 26.2 of the CVM Official Letter SNC/SEP 1, of February 14, 2007. In our opinion, these proposals comply with current legal and statutory provisions and the Company's interests, therefore, should be fully approved by the Board of Directors, the Fiscal Council and the Annual General Meeting.
