Manual for participation in General Meetings 15/30 IV. MANAGEMENT PROPOSAL In order to facilitate the understanding and participation of the Shareholder Lords in the Meeting, clarifications of the Company's Management on the matters that will be the subject of a deliberation to exercise the conscious vote are presented below. *** 1. AUTHORIZATION FOR THE COMPANY'S ADMINISTRATORS TO SUBMIT TO B3 S.A. - BRAZIL, STOCK EXCHANGE, COUNTER ("B3") A REQUEST FOR ENTRY OF THE COMPANY, EVEN IF CONDITIONED, IN THE SPECIAL SEGMENT OF THE B3 STOCK MARKET CALLED THE NOVO MERCADO AND ADMISSION OF THE COMPANY'S SHARES TO NEGOTIATION IN SAID SEGMENT Clarifications In line with the constant search for improvement of corporate governance, and following the process initiated in recent years, the Company’s management submits to the Shareholders’ Meeting the proposal for Copel to join and effectively list its shares in the special segment of the B3 stock market called Novo Mercado, which is exclusive for companies that adopt the highest corporate governance practices (“Migration to the Novo Mercado”). Among rules in force, we highlight the division of capital into voting shares only, favoring the principle of “one share, one vote”, as well as the requirement of specific policies and collegiate bodies, many of which are already voluntarily adopted by the Company due to its commitment to best practices. Migration to the Novo Mercado, therefore, requires the conversion of preferred shares of the Company into common shares. the conversion of shares mentioned above and comply with the mandatory rules of the Novo Mercado segment, it will be necessary to amend the Company’s Bylaws. The proposal for reform of the Bylaws for this purpose is presented in item 8 of this Proposal (and is further detailed in Appendices II, III and IV). In addition, it should be emphasized that the subject matters object of items 2, 3, 4 and 5 of this Proposal also refer to amendments necessary to enable the implementation of the steps that make up the proposed structure for Migration to the Novo Mercado, as highlighted throughout this Proposal. Thus, we subject for Shareholders approval the authorization for the Company to request its admission to the Novo Mercado segment, observing that the effective approval by B3 may be conditioned on the conversion of shares, approval of the amendment of Bylaws discussed below and the approval of policies and rules of procedure, among other requirements. Voting right Manual for participation in General Meetings 16/30 Holders of common shares have the right to vote on this item of the agenda. Additionally, pursuant to Article 6 of the Company’s bylaws, no shareholder or group of shareholders, Brazilian or foreign, public or private, may exercise voting rights in excess of the percentage equivalent to 10% (10 percent) of the total number of shares into which Copel’s voting capital is divided, regardless of their stake in the share capital. Approvals This matter was subject to review by the Board of Directors, at its 258th Extraordinary Meeting, held on June 23, 2025, and at its 259th Extraordinary Meeting, held on July 11, 2025; and by the Supervisory Board, at its 536th Meeting, held on June 23, 2025, and at its 537th Meeting held on July 11, 2025. 2. AMENDMENT OF THE STATUTORY RULES APPLICABLE TO THE CONVERSION OF SHARES, WITH THE EXCLUSION OF ITEM III OF § 11 OF ART. 5 OF THE COMPANY’S BYLAWS TO ENABLE PN UNIFICATION (AS DEFINED IN ITEM 4 BELOW), NOTING THAT THE EFFECTIVENESS OF THIS AMENDMENT WILL BE SUBJECT TO THE APPROVAL OF CREDITORS WHOSE FINANCIAL INSTRUMENTS PROVIDE FOR THE EARLY MATURITY OF THE DEBTS OF THE COMPANY OR ITS SUBSIDIARIES AS A RESULT OF THE APPROVAL OF ANY MATTERS PROVIDED HEREIN (“WAIVERS”); Clarifications The current wording of Art. 5, § 11, of the Company's Bylaws provides for certain rules of conversion of shares, essentially establishing that: (i) class A preferred shares (“PNA”) may be converted into class B preferred shares (“PNB”), at any time; (ii) PNA and PNB shares may be converted into common shares, in accordance with the terms, conditions and procedures defined by the Board of Directors; and (iii) common shares and the PNB shares may not be converted into PNA shares under any circumstances. Firstly, it should be noted that these conversion rules were introduced in another context, when the Company still had the Units Program, extinguished in 2023. Thus, these rules are no longer justified i view of the current composition of the Company's share capital and the proposed Migration to Novo Mercado. As highlighted above, the Company intends to carry out the Migration to Novo Mercado, which requires the conversion of PNA and PNB shares into common shares. In this sense, in line with the following items of the agenda of this Meeting, the structure proposed by Management to enable Migration to the Novo Mercado will include, in summary: Manual for participation in General Meetings 17/30 (a) the change in the preferences and advantages of PNB shares to match PNA shares, with the subsequent unification of the PNA and PNB classes (collectively referred to as “PN”) through the mandatory conversion of all PNB shares into PNA (“PN Unification”); (b) the creation of a new class C preferred share (“PNC”) compulsorily redeemable, without the need for approval at a special meeting of holders of PNC shares, pursuant to art. 44, §6, of the Brazilain Corporate Law; (c) the mandatory conversion of all PN shares into common shares and PNC shares, observing the proportion of one new common share and one new PNC share for each PN share (“PN Conversion”), the effectiveness of which will be subject to the implementation of certain suspensive conditions, detailed in item 6 of this Proposal; and (d) conditioned on PN Conversion, the application of the available reserves in the mandatory redemption of all PNC shares for the amount of BRL 0.7749 per share, without modification of the share capital ("Rescue"). To enable the implementation of the above steps, particularly PN Unification, the Company's management proposes to previously exclude Art. 5, §11, III, of the Bylaws, revoking the restriction on the conversion of common shares and PNB shares into PNA shares. The Company's management understands that there is no reason to maintain such restriction, either because it was created in a specific context, connected to a unit-based capital structure, which no longer exists, or because, after the preferences and advantages of PNB shares have been equalized with those of PNA shares, nothing prevents the unification of PNB and PNA, through the mandatory conversion of PNB to PNA. The updated wording of Art. 5 of the Company's Bylaws, without this restriction, is highlighted in the table contained in item 3 below. It should be noted too that, at the end of the Migration to Novo Mercado process, considering the implementation of the PN Conversion and of the Statutory Reform proposed in item 8 of the agenda, the wording presented in Appendices II, III and IV to this Proposal shall prevail. Finally, one must bear in mind that the effectiveness of this statutory reform is conditioned on obtaining the Waivers. Given that this deliberation is conditional on obtaining the Waivers, the Company's management clarifies that it has already started analysing its financial contracts and negotiating in order to obtain the necessary approvals from the creditors whose contracts provide for early maturity due to the changes proposed herein. The Board of Directors will meet in due course to certify compliance with this condition, keeping its shareholders and the market in general informed about the effectiveness of this resolution. Manual for participation in General Meetings 18/30 Voting right Holders of common shares have the right to vote on this item of the agenda. Additionally, pursuant to Article 6 of the Company’s bylaws, no shareholder or group of shareholders, Brazilian or foreign, public or private, may exercise voting rights in excess of the percentage equivalent to 10% (10 percent) of the total number of shares into which Copel’s voting capital is divided, regardless of their stake in the share capital. Approvals This matter was subject to review by the Board of Directors, at its 258th Extraordinary Meeting, held on June 23, 2025, and at its 259th Extraordinary Meeting, held on July 11, 2025; and by the Supervisory Board, at its 536th Meeting, held on June 23, 2025, and at its 537th Meeting held on July 11, 2025. 3. CHANGE IN PREFERENCES AND ADVANTAGES CONFERRED TO CLASS “B” PREFERRED SHARES (“PNB”) TO MATCH CLASS “A” PREFERRED SHARES (“PNA”), WITH THE PERTINENT AMENDMENT OF ART. 5. OF THE COMPANY’S BYLWAS, CONDITIONED ON OBTAINING WAIVERS Clarifications The proposal provides for the amendment of Art. 5 of the Bylaws to change the preferences and advantages currently conferred on PNB shares, in order to match them to those conferred on PNA shares, observing that the effectiveness of this deliberation will be conditioned on the obtaining of Waivers. Under this Proposal, once Waivers are obtained, the preferences and advantages of the PNA and PNB shares would be equalized and such modification would be reflected in the wording of Art. 5 of the Bylaws, to the extent that PNB shares would have priority in the distribution of minimum dividends of 10% (ten percent) per year, that would be apportioned among them equally, calculated on the basis of equity corresponding to that type and class of shares, paid up until December 31 of the immediately preceding fiscal year, an amount that would be imputed to the mandatory dividend. In view of this scenario, management subjects to Shareholders’ approval the amendment of Art. 5, § 7, I, IV, V and VI; the exclusion of Art. 5, § 7, II and III; and the renumbering of the other items of said paragraph, so that, between obtaining the Waivers and the effective Migration to the Novo Mercado, Art. 5, § 7, of the Company's Bylaws would come into force with the following new wording: “Art. 5 (...) § 7 Preferred shares shall give their holders the following preferences and advantages: Manual for participation in General Meetings 19/30 I. Preferred shares shall have priority in the distribution of minimum dividends of 10% (ten percent) per year, to be equally apportioned among them, on the basis of equity corresponding to this type of shares, paid up until December 31 of the immediately preceding fiscal year, an amount that will be imputed to the mandatory dividend provided for in Article 87; II. The dividend to be paid to each prefered share shall be at least 10% (ten percent) higher than that attributed to each common share, in accordance with the provisions of Federal Law No. 6,404/1976 and subsequent amendments; III. Preferred shares shall acquire the right to vote if, for a period of 03 (three) consecutive years, they are not paid the priority or minimum dividends to which they are entitled; IV. Preferred shares insure their holders the right to be included in a public offer to acquire shares as a result of the Disposal of Company Control at the same price and under the same conditions offered to the Disposing Controlling Shareholder; V. The special class preferred share held by the State of Paraná will give the State of Paraná priority in the reimbursement of capital, without premium, in the event of liquidation of the company, corresponding to the percentage of the share capital that such share represents, and the power to veto in general meeting resolutions (...)” Additionally, considering the proposal to match preferences and advantages between PNB and PNA shares, with the subsequent unification of the classes, it is reiterated that, in line with item 2 of the agenda, the Company's management also proposes the exclude Art. 5, § 11, III, which currently prohibits the conversion of PNB shares into PNA shares. These changes are consolidated in the table below. In compliance with art. 12, II, of RCVM 81, please find highlighted below the changes proposed to theBylaws in items 2 and 3 of this agenda, and the report that details the origin and justification of the proposed reform, analyzing itslegaland economic effects: Current Articles of Incorporation Proposed Amendment to Bylaws Art. 5.

Rationale and Impacts: The amendment tothe statutory provisionsherein aims to reflect the equivalence between the preferences and advantages conferred on PNA shares and PNB shares, in the context of the proposal to unify the preferred share classes object of item “4” on the agenda. In this regard, Management clarifies that the PNA and PNB shares issued by tha Company currently have substantially equal rights, sharing the same political rights and, in practical terms, similar economic rights, as can be seen from the current version of Art. 5 of its Bylaws. It is worth noting that, when examining the preferences and advantages expressed in Art. 5, §7, I, one can see that the Company’s Bylaws establish a priority, intended for PNA shares, in the distribution of minimum dividends of 10% per year, to be equally apportioned among them, calculated on the basis of the equity of this type and class of shares, paid up by December 31 of the precedidng fiscal year, and that it will be attributed to the mandatory dividend. Nevertheless, in light of the Company’s current Dividend Policy (NPC 0107 Dividend Policy), whose last version was approved by the 262nd Ordinary Meeting of the Board of Directors held on May 8, 2025 (“Dividend Policy”), the parameters for defining the annual amount of dividend to be paid out by the Company consider, as a rule, the minimum of 75% of net profit earned – which, in practical terms, as has been the case in recent years, implies an equality of economic rights between the PNA and PNB classes. Nevertheless, in order to remedy this formal distinction, the Company's management proposed, in this item 3 of the agenda of this Meeting, the change of preferences and advantages of PNB shares, in order to also equalize them in formal aspects to PNA shares, in the terms provided for in the Bylaws - including with respect to such right of priority in the receipt of dividends. The changes described above in the preferences and advantages of PNB shares do not imply any loss to holders of PNA or PNB shares. The Company's management considers this amendment tobe both relevant and timelyin the context of the proposal to unify the preferred share classes in order to enable the Company's migration to the Novo Mercado. Additionally, by equalizing the preferences and advantages attributed to the PNA and PNB classes in its Bylaws, the Company's management understands that it formally recognizes the equivalence of the rights conferred to each preferred share class, especially in light of the Company's current dividend policy. Manual for participation in General Meetings 22/30 The Company's management also notes that, if the PN Conversion and Migration to the Novo Mercado are approved and the suspensive conditions for migration are verified, the current holders of PNA and PNB shares will have their shares converted into common shares, favoring the composition of the Company's share capital required to enable entry into the Novo Mercado. Finally, it should be noted that, if approved, the amendment can grant the holders of common shares the right of recess, pursuant to the terms presented below. Given that this resolution is conditioned on obtaining the Waivers, the Company's management reinforces that it has started analysing its financial contracts and negotiations in order to obtain the necessary approvals from the creditors whose contracts provide for early maturity due to the changes proposed herein. The Board of Directors will meet in due course to certify compliance with this condition, keeping its shareholders and the market in general informed about the effectiveness of this resolution. With regard to item 3 on the agenda, management notes that shareholders holding common shares that do not approve the change of preferences and advantages conferred to PNB shares to match PNA shares - whether by dissention, abstention or absence - will have the right to withdraw from the Company, through the reimbursement of shares that are proven to be held uninterruptedly between this date and the date of effective exercise of the right of recess, pursuant to Art. 137, § 1, of the Corporations Law. It is also important to note that Copel reserves the right to convene a general meeting to ratify or reconsider this resolution, if management believes that the payment of the price of reimbursement of common shares to dissidenting shareholders who exercised the right of withdrawal will jeopardize the financial stability of the Company, pursuant to Art. 137, §3, of the Corporation Law. It should also be noted that, pursuant to Article 107 of the Company's current Bylaws, in the event of exercise of the right of withdrawal by shareholders holding common shares, the reimbursement amount will correspond to the book equity value of the share, calculated on the basis of the net equity contained in the last financial statements approved by the general meeting, ensuring the right to draw up a special balance sheet, as provided for in Art. 45 of the Brazilian Corporate Law. The information relating to the right of withdrawal applicable to potentially dissenting holders of common shares, in compliance with Article 21 of the RCVM 81, can be found in Appendix I to this Proposal. Voting right Holders of common shares have the right to vote on this item of the agenda. Additionally, pursuant to Article 6 of the Company’s bylaws, no shareholder or group of shareholders, Brazilian or foreign, public or private, may exercise voting rights in excess of the percentage equivalent to 10% (10 percent) of the total number of shares into which Copel’s voting capital is divided, regardless of their stake in the share capital. Approvals This matter was subject to review by the Board of Directors, at its 258th Extraordinary Meeting, held on June 23, 2025, and at its 259th Extraordinary Meeting, held on July 11, 2025; and by the Manual for participation in General Meetings 23/30 Supervisory Board, at its 536th Meeting, held on June 23, 2025, and at its 537th Meeting held on July 11, 2025. 4. CONDITIONED ON THE APPROVAL OF ITEMS “2” AND “3” ABOVE, THE UNIFICATION OF THE PNA AND PNB SHARE CLASSES (PNA AND PNB, TOGETHER, “PN”), THROUGH THE MANDATORY CONVERSION OF ALL PNB SHARES INTO PNA (“PN UNIFICATION”), WITH THE RESPECTIVE AMENDMENT OF ART. 5 OF THE COMPANY’S BYLAWS, WHOSE EFFICACY WILL BE SUBORDINATED TO OBTAINING WAIVERS Clarifications As highlighted above, the PN Unification, substantiated in the conversion of PNB shares into PNA shares, must occur prior to the PN Conversion and the implementation of the Migration to the Novo Mercado. Once the preferences and advantages of the PNA and PNB shares (object of item 3 of the agenda) have been formally equalized, the Company's management understands that the most appropriate measure is the PN Unification, in order for the holders of PNA shares and PNB shares to jointly decide on the PN Conversion within the scope of a special meeting of preferential shareholders, pursuant to Art. 136, §1, of the Corporations Law. The joint decision is justified not only because the legal status of the current holders of PNA and PNB shares will be equivalent and because such shareholders will be subject to the same effects of the proposed operation, and there will be no loss of right to the PN share classes. In addition, distortions are avoided in the decision-making process, especially considering the small representation of PNA shares in the total share capital of the Company and its high degree of share dispersion. Thus, the proposal for PN Unification presented herein, whose effectiveness remains subject to obtaining the Waivers described in item 3 above, becomes a fundamental measure to enable the appropriate resolution on the subsequent PN Conversion and Migration to the Novo Mercado. Finally, the Management emphasizes that the changes to Art. 5 of the Bylaws to reflect the PN Unification are already described in the table in item 3 above. Voting right Holders of common shares have the right to vote on this item of the agenda. Additionally, pursuant to Article 6 of the Company’s bylaws, no shareholder or group of shareholders, Brazilian or foreign, public or private, may exercise voting rights in excess of the percentage equivalent to 10% (10 percent) of the total number of shares into which Copel’s voting capital is divided, regardless of their stake in the share capital. Approvals This matter was subject to review by the Board of Directors, at its 258th Extraordinary Meeting, held on June 23, 2025, and at its 259th Extraordinary Meeting, held on July 11, 2025; and by the Manual for participation in General Meetings 24/30 Supervisory Board, at its 536th Meeting, held on June 23, 2025, and at its 537th Meeting held on July 11, 2025 5. AMENDMENT OF ART. 5 OF THE COMPANY’S BYLAWS FOR CREATION OF CLASS “C” PREFERRED SHARES, NOMINATIVE, BOOK-ENTRY AND WITHOUT NOMINAL VALUE (“PNC”), COMPULSORILY REDEEMABLE, WITHOUT THE NEED FOR APPROVAL AT A SPECIAL MEETING OF PNC SHAREHOLDERS, UNDER § 6 OF ART. 44 OF THE BRAZILIAN CORPORATE LAW Clarifications The proposal provides for the amendment of Art. 5 of the Bylaws to create a new class of preferred shares, called “PNC”, nominative, book-entry and without nominal value, compulsorily redeemable. In the context of the Migration to the Novo Mercado, as indicated in the items above, the Company's share capital should be exclusively composed of voting shares, which will require the conversion of the PN shares (current PNA and PNB shares, which will be unified) into common shares, if the proposal contained in item 4 above (PN Unification) is approved by the EGM. The structure proposed by the Company's management to enable this conversion of shares - PN Conversion, detailed in item 6 below - assumes, in summary: (a) the creation of the new PNC preferred share class; and (b) the mandatory conversion of all PN shares into common shares and "PNC" shares, observing the proportion of 1 common share and 1 PNC share for each 1 PN share. Accordingly, in the event of approval, current holders of PNA and PNB shares will receive 1 common share and 1 compulsorily redeemable PNC share. The PNC share created herein would be redeemed immediately after conversion, without the need for new approval at a Special Meeting of the PNC shareholders, as authorized by article 44, §6, of the Brazilian Corporate Law. The terms and conditions of the redemption of PNC shares are detailed in item 4 of this Proposal Under the proposed terms, PNC shares will have the following characteristics, rights and advantages, to be provided for in Article 5 of the Bylaws, as below: “Art. 5. (...) § 1. Subject to the provisions of Article 100, the Company may, by resolution of the General Meeting, issue preferential, nominative and non-nominal shares, which will have the following characteristics, rights and advantages: I. except for the provisions of the Level 2 Regulation until migration to the Novo Mercado, they shall not grant the holder the right to vote in the resolutions of the General Meeting, nor shall they acquire the right to vote fully in the event of non-declaration or payment of the proceeds to which they are entitled; II. they shall grant priority to repayment of capital in the event of liquidation of the Company's Manual for participation in General Meetings 25/30 assets, without premium, in the amount corresponding to the percentage of the share capital represented by such share; III. they are automatically and compulsorily redeemable immediately upon issuance, without the need for a special meeting of holders of preferred shares, for the amount to be defined at the time of its issuance, to be paid in national currency on the date of redemption, occasion on which the Company is permitted to withhold amounts for tax payment purposes, taxes, fees and expenses for which, by law, the Company is responsible for withholding at the source on behalf of the shareholder. IV. they confer the right to receiving proceeds on equal terms with the common shares issued by the Company; and V. they confer the right to be included in a public offer of disposal of control, on equal terms with common shares.” It should be emphasized that the proposal to amend Article 5 of the Bylaws, pursuant to the above terms, is already included in Appendices II, III and IV to this Management Proposal, which, in compliance with the provisions of Article 12 of RCVM 811, highlight the changes proposed to the Company's Bylaws (including the reform proposed in item 8 of the agenda), detailing the origin and justification of the proposed changes and analysis of their legal and economic effects. It is also noted that, in compliance with Article 18 of RCVM 81, Appendix V to this Management Proposal provides information relating to the creation of a new preferred share class. Finally, Appendix VI also provides information relating to the right of withdrawal to the holders of PN shares, as required by Article 21 of RCVM 81. Voting right Holders of common shares have the right to vote on this item of the agenda. Additionally, pursuant to Article 6 of the Company’s bylaws, no shareholder or group of shareholders, Brazilian or foreign, public or private, may exercise voting rights in excess of the percentage equivalent to 10% (10 percent) of the total number of shares into which Copel’s voting capital is divided, regardless of their stake in the share capital. Approvals This matter was subject to review by the Board of Directors, at its 258th Extraordinary Meeting, held on June 23, 2025, and at its 259th Extraordinary Meeting, held on July 11, 2025; and by the 1 For clarification purposes, the appendices related to the Bylaws include the following information: Annex II - Company Bylaws reflecting, among other changes, the new wording of Art. 5, with the proposed changes highlighted, in accordance with Art. 12 of RCVM 81.

CONDITIONED ON THE APPROVAL OF PN UNIFICATION, MANDATORY CONVERSION OF ALL PN SHARES INTO COMMON SHARES AND PREFERRED PNC SHARES, OBSERVING THE PROPORTION OF ONE NEW COMMON SHARE AND ONE NEW PNC SHARE FOR EACH PN SHARE (“PN CONVERSION”), THE EFFECTIVENESS OF WHICH WILL BE SUBJECT TO THE IMPLEMENTATION OF THE FOLLOWING SUSPENSIVE CONDITIONS (“SUSPENSIVE CONDITIONS - NM”): (i) RATIFICATION OF THE PN CONVERSION AT A SPECIAL MEETING OF PREFERRED SHAREHOLDERS, PURSUANT TO ART. 136, § 1 OF THE BRAZILIAN CORPORATE LAW (“PN RATIFICATION”); (ii) OBTAINING WAIVERS; AND (iii) EFFECTIVE ENTRY OF THE COMPANY INTO THE NOVO MERCADO SEGMENT AND EFFECTIVE ADMISSION TO TRADING OF THE COMPANY'S SHARES IN THE NOVO MERCADO SEGMENT ("MIGRATION TO NOVO MERCADO"). Clarifications As highlighted above, to enable Migration to the Novo Mercado, the Company's management proposes a structure that includes the PN Conversion, namely, the mandatory conversion of all PN shares (currently PNA and PNB shares unified) into common shares and PNC shares - observing the proportion of 1 common share and 1 PNC share for each 1 PN share. It should be emphasized once again that the PN Conversion is necessary to meet the requirements of the Novo Mercado Regulation. Pursuant to Art. 8 of the Regulation, except for special classes of preferred shares in the event of destatization – as attributed to the State of Paraná pursuant to Art. 5 of the Bylaws – the share capital of the companies listed in the Novo Mercado must be divided exclusively into common shares. For clarification purposes, the preferred shares owned by the State of Paraná will not be subject to any modification in this Migration to the Novo Mercado process. Thus, the Company's management proposes that the Shareholders decide on the PN Conversion, the effectiveness of such conversion being conditioned on: (i) ratification by the holders of preferred shares (unified PNA and PNB shares) gathered at a special meeting, pursuant to Art. 136, §1 of the Brazilian Corporate Law, to be convened in due course (“PN Classification”); (ii) obtaining the Waivers; and (ii) migration to the Novo Mercado, with the effective admission of shares issued by the Company to trading in the segment. With regard to the Suspensive Conditions - NM, the Company's management reinforces that it will adopt all the relevant measures for its compliance. Manual for participation in General Meetings 27/30 Firstly, preferred shareholders will be convened to decide on PN Ratification at a special meeting (“AGESP PN”), as set forth in Article 136, §1, of the Corporations Law. The convening of the AGESP PN will only occur after the approval of the PN Unification (and obtaining of Waivers), so that, at the time of the AGESP PN, the necessary corporate approvals to enable the PN Unification (object of items 2, 3 and 4 of the agenda of this EGM) will have been obtained. In this sense, the current shareholders holding PNA and PNB shares will participate in the same special meeting, on equal terms, and the matter will be considered approved, pursuant to §1 of Art. 136 of the Brazilian Corporate Law, upon approval by holders of more than half of the PN shares (which, as mentioned, shall include the current PNA and PNB shares, considering the PN Unification). The convening of AGESP PN, with the information pertinent to the resolution by the PN shareholders, will be timely disclosed to the market by the Company's management. The current holders PNA and PNB shares who do not approve the PN Conversion in AGESP PN - either by dissention, abstention or absence —shall have the right to withdraw from the Company, through reimbursement of the shares that they are proven to be uninterrupted holders between the date of the relevant fact that announced the PN Conversion, on June 23, 2025 (date the transaction was disclosed to the market), and the effective exercise date of the right of wihdrawal, pursuant to art. 137, § 1, of the Brazilian Corporate Law. It is also important to note that Copel reserves the right to convene a general meeting to ratify or reconsider the deliberation, if Management believes that the payment of the price of reimbursement of the PN shares to the dissenting shareholders who exercised the right of withdrawal will jeopardize the financial stability of the Company, pursuant to Art. 137, §3, of the Corporation Law. It should also be emphasized that, pursuant to Article 107 of the Company's Bylaws, in the event of exercise of the right of withdrawal by shareholders holding PN shares, the amount of reimbursement will correspond to the book equity value of the share, calculated based on the net equity contained in the last financial statements approved by the general meeting, ensuring the right to draw up the special balance sheet provided for in Art. 45 of the Corporate Law. With regard to the Waivers, the Company's management reiterates that it has already started the analyses for its obtaining and will conduct the pertinent negotiations with the creditors in a timely manner. Finally, the PN Conversion also remains conditional on the Migration to the Novo Mercado – the order of which will be submitted to B3, as proposed in item 1 of the agenda of this Meeting. In this regard, the Company only clarifies that this condition will be considered fulfilled when B3 approval occurs, even if conditional, and the setting of the date on which the Company's shares will be traded on the Novo Mercado, without prejudice to any operational aspects necessary to carry out the PN Conversion itself. It should be noted that if the PN Conversion is concluded, the Company's capital will be divided exclusively into common, nominative, book-entry shares and without nominal value, with the exception of the Golden Share owned by the State of Paraná. Manual for participation in General Meetings 28/30 Information regarding the right of withdrawal arising from the PN Conversion, in compliance with Article 21 of the 81 RCVM, is found in Annex VI to this Proposal. Voting right Holders of common shares have the right to vote on this item of the agenda. Additionally, pursuant to Article 6 of the Company’s bylaws, no shareholder or group of shareholders, Brazilian or foreign, public or private, may exercise voting rights in excess of the percentage equivalent to 10% (10 percent) of the total number of shares into which Copel’s voting capital is divided, regardless of their stake in the share capital. Approvals This matter was subject to review by the Board of Directors, at its 258th Extraordinary Meeting, held on June 23, 2025, and at its 259th Extraordinary Meeting, held on July 11, 2025; and by the Supervisory Board, at its 536th Meeting, held on June 23, 2025, and at its 537th Meeting held on July 11, 2025 7. CONDITIONED ON THE PN CONVERSION, APPLICATION OF AVAILABLE RESERVES IN THE COMPULSORY REDEMPTION OF ALL THE PN SHARES, FOR THE AMOUNT OF R$ 0.7749 PER SHARE, WITHOUT MODIFICATION OF THE SHARE CAPITAL ("REDEMPTION") Clarifications In order to promote adherence and encourage shareholder approval of the transaction, especially the current holders of PNA and PNB shares, the Company's management proposes that the Conversion of Shares include, in addition to the delivery of the corresponding number of common shares (in the proportion of 1 common share for each PN share, as applicable), the delivery of 1 compulsorily redeemable PNC share, with the characteristics, rights and advantages provided for in item 5 of this Proposal. The Company's management proposes that the redemption, to be carried out immediately after the PN Conversion, be effected at the amount of R$ 0.7749 per PNC share redeemed. Under the proposed terms, the Redemption will be effective without reduction of share capital, through the application of available profit and capital reserves. The Company emphasizes that the Redemption is conditioned on the prior implementation of the PN Conversion. Finally, the Company reinforces that Redemption will not be subject to the approval of the holders of "PNC" shares, in view of the proposal to amend Art. 5 of the Bylaws and the provisions of Art. 44, § 6, of the Corporate Law. Voting right Holders of common shares have the right to vote on this item of the agenda. Additionally, pursuant to Article 6 of the Company’s bylaws, no shareholder or group of shareholders, Brazilian or foreign, public or private, may exercise voting rights in excess of the percentage equivalent to 10% (10 percent) of the total number of shares into which Copel’s voting capital is divided, regardless of their stake in the share capital.

The effectiveness of the Shareholders’ resolution that approves the Amendment of Bylaws will be subject to the effective PN Conversion, which, in turn, is subject to the implementation of the Suspensive Conditions - NM detailed in item 6 above. Finally, it should be emphasized that the information required by RCVM 812, in the context of the reform of the Bylaws proposed herein, can be found in Appendices II, III and IV to this Management Proposal.

Describe the event that gave or will give rise to the withdrawal and its legal basis Under this Proposal, with the objective of enabling the migration of the Company to the Novo Mercado segment of B3, the Company's management proposed to its shareholders, among other matters, the change in preferences and benefits conferred to class “B” preferred shares (“PNB”) to match class “A” preferred shares (“PNA”), with the respective amendment of Art. 5 of the Company's Bylaws, whose effectiveness will be subject to the approval of creditors whose financial instruments provide for the early maturity of the debts of the Company or its subsidiaries as a result of the approval of any matters provided herein (“Waivers”). Pursuant to Article 136, II, of the Brazilian Corporate Law, the structure proposed above, with the equalizing of the preferences and advantages conferred on PNA shares with PNB shares, involves matters that, under the terms of the Brazilian Corporate Law (art. 137, I), confer the right of withdrawal to the holders of common shares, in view of the expansion of preferences and advantages of the former PNB shares. Shareholders who hold common shares that do not approve the change in preferences and advantages conferred to PNB shares to match PNA shares – whether by dissention, abstention or absence – will have the right to withdraw from the Company, through the reimbursement of shares of which they are proven to be uninterrupted holders between this date and the date of effective exercise of the right of withdrawal, pursuant to Art. 137, § 1, of the Brazilian Corporate Law. The criteria for calculating the reimbursement amount in the event of exercising of the right of withdrawal are provided for in item 5 below. Finally, the Company notes that it reserves the right to convene a general meeting to ratify or reconsider the decision, if administrators understand that payment of the price of the reimbursement of common shares to dissenting shareholders who exercised the right of withdrawal will put the financial stability of the Company at risk, pursuant to Art. 137, §3, of the Brazilian Corporate Law. 2. Report the shares and classes to which the withdrawal applies The right of withdrawal will be applicable to holders of common shares that do not approve – whether by dissention, abstention or absence – the change of preferences and advantages conferred on the PNB to match the PNA at the General Shareholders’ Meeting. 3. Inform the date of the first publication of the call notice of the meeting, as well as the date of communication of the material fact regarding the decision that gave or will give rise to the withdrawal The Material Fact regarding the proposals that will give rise to the right of withdrawal is disclosed by the Company on this date, July 11, 2025. The re-ratification of the call notice of this Meeting which included the proposal was originally published on July 11, 2025. 4. Inform the deadline for exercising the right of withdrawal and the date that will be considered for the purpose of determining the holders of the shares that may exercise the right of withdrawal Uninterrupted holders of common shares between July 11, 2025 and the date of effective exercise of the right of withdrawal, pursuant to Art. 137, § 1, of the Brazilian Corporate Law. Among such shareholders, those holders of common shares who do not approve – whether by dissention, abstention or absence, at the General Meeting, the change of preferences and advantages conferred on PNBs to match PNAs may exercise the right of withdrawal. Pursuant to Art. 137, IV, of the Brazilian Corporate Law, the deadline for exercising the right of withdrawal, under penalty of forfeiture, will be up to 30 days from the date of publication of the minutes of the EGM. 5. Report the amount of the reimbursement per share or, if it is not possible to determine it in advance, the management estimate of this amount Pursuant to Article 107 of the Company's Bylaws, in the event of exercise of the right of withdrawal by shareholders holding common shares, the amount of reimbursement will correspond to the book equity value of the share, calculated based on the net equity contained in the last financial statements approved by the general meeting, ensuring the right to draw up the special balance sheet provided for in Art. 45 of the Brazilian Corporate. Based on this criterion, the equity value of the Company's shares calculated based on the financial statements for the fiscal year ended December 31, 2024, adjusted based on the net equity divided by the number of outstanding shares, excluding shares in treasury, would correspond to BRL 8.6467556201 per share. 6.

Appendix V INFORMATION REGARDING THE CREATION OF A NEW PREFERRED SHARE CLASS (PNC), ACCORDING TO ART. 18 RCVM 81 1. If Preferred Stock or New Preferred Stock Class is Created a) Present rationale, in detail, for the proposal to create shares The proposal to create the new compulsorily redeemable PNC shares falls within the context of the Company's migration to the Novo Mercado. Due to the requirements set forth in the Novo Mercado Regulation, especially the one set forth in Art. 8, the Company's share capital must be exclusively composed of voting shares, which will require the conversion of preferred shares ("PN"). In order to promote adhesion and stimulate approval of the operation by shareholders, particularly the current holders of PN shares, the Company's management proposes that the PN Conversion (as detailed in item 6 of this Proposal) include, in addition to the delivery of the corresponding number of common shares (in the proportion of 1 common share for each PN share), also the delivery of 1 compulsorily redeemable PNC share. The creation and granting of compulsorily redeemable PNC shares to the holders of PN shares may contribute to the execution of the operation, insofar as it is predicted that, immediately after the PN Conversion, the compulsory redemption of such PNC shares will occur at the amount of R$ 0.7749 per PNC share redeemed. Thus, at the end, by virtue of the PN Conversion, the holders of PN shares would receive, in return, 1 common share for each PN share as well as the amount corresponding to R$ 0.7749 per share. It should be noted that, pursuant to Articles 5 and 100 of the amended Bylaws as proposed to the Extraordinary General Meeting scheduled to be held, on the first call, on August 22, 2025, the statutory authorization for the creation of the PNC shares will no longer in force with the admission and effective trading of the shares issued by the Company in the Novo Mercado. b) Describe, in detail, the rights, advantages and restrictions to be attributed to the shares to be created, in particular: i. Increased dividends in comparison to common shares ii. Fixed or minimum dividends iii. Possible cumulative nature of dividends iv. Right to participate in remaining profits v. Right to receive dividend to the capital reserve account vi. Capital reimbursement priority vii. Equity Reimbursement Premium viii. Voting right ix. Statutory right to elect board members by separate vote x. Right to be included in the public offer to acquire shares in the event of disposal of control provided for in art. 254-A of Law No. 6.404, of 1976 xi. Right to veto in relation to statutory amendments xii. Redemption Terms and Conditions xiii. Amortization Terms and Conditions Under the terms described in this Proposal, the PNC shares to be issued would be compulsorily redeemed, immediately after the PN Conversion, upon payment of the amount of R$ 0.7749 per PNC share redeemed. As provided for in Art. 5 of the draft Bylaws submitted for EGM approval, the PNC shares to be issued – and compulsorily redeemed – would have the following characteristics, rights and advantages: (i) except for the provisions of the Level 2 Regulation until migration to the Novo Mercado, they do not grant the holder the right to vote in the resolutions of the General Meeting, nor will they acquire the right to vote fully in the event of non-declaration or payment of the proceeds to which they are entitled; (ii) they grant the priority of capital reimbursement in the event of liquidation of the Company's assets, without premium, in the amount corresponding to the percentage of the share capital represented by such share; (iii) they are automatically and compulsorily redeemable immediately upon issuance, without the need for a special meeting of shareholders holding preferred shares, the amount to be defined at the time of its issuance, to be paid in national currency on the date of redemption, with the Company being permitted to withhold amounts for the purpose of paying taxes, fees and expenses for which, by law, the Company is responsible for withholding at the source on behalf of the shareholder; (iv) they grant the right to receive proceeds on equal terms with the common shares issued by the Company; and (v) they confer the right to be included in any public offer of disposal of control, on equal terms with common shares. c) Provide detailed analysis of the impact of the creation of shares on the rights of holders of other types and classes of shares of the company Under the terms described in item 1(a) above, the management clarifies that the creation of PNC shares falls within the context of the Migration to the Novo Mercado, having been structured in order to promote and stimulate the adhesion and approval of the operation by the Company's shareholders, especially by the holders of PN shares – who would receive PNC shares in the context of the PN Conversion. In this sense, considering that the PNC shares would be compulsory and immediately redeemed shortly after the PN Conversion, the management does not envision relevant impacts for the other shareholders of the Company. 2. If preferences, advantages or conditions for redemption or amortization of preferred shares change a) Describe in detail the proposed changes b) Rationale, in detail, the proposed changes c) Provide detailed analysis of the impact of the proposed changes on the holders of the shares subject to the change d) Provide detailed analysis of the impact of proposed changes on the rights of holders of other species and share classes of the company As highlighted above, PNC shares would be issued only in the context of the PN Conversion of PN shares. In this context, if the issuance of the PNC shares, the PN Conversion and the respective Redemption are approved, the PN shares would be extinguished - consedering that their holders would receive common shares and compulsorily redeemable PNC shares - observing the proportion of 1 common share and 1 PNC share for each 1 PN share. Appendix VI INFORMATION RELATING TO THE RIGHT OF WITHDRAWAL, IN ACCORDANCE WITH ART. 21 OF COVM 81 (ANNEX H OF COVM 81) 1. Describe the event that gave or will give rise to the withdrawal and its legal basis Pursuant to this Proposal, with the objective of enabling the migration of the Company to the Novo Mercado segment of B3, the Company's management proposed to its shareholders, among other matters: (a) the creation of the new PNC preferred share class, compulsorily redeemable; and (b) the mandatory conversion of all PN preferred shares (already considering the PN Unification) into common shares and PNC shares – observing the proportion of 1 common share and 1 PNC share for each 1 PN share (“PN Conversion”). It should be emphasized that, pursuant to the terms of art. 136, I and II, of the Brazilian Corporate Law, the structure proposed above, with the creation of redeemable PNC shares, and the PN Conversion, involves matters that, under the terms of the Brazilian Corporate Law (art. 137, I), confer the right of withdrawal to the current holders of the PNA and PNB shares – which, under the terms of the PN Unification, if approved, will become holders of PN shares. Accordingly, the PN Conversion is subject to the implementation of the Suspending Conditions detailed in item 6 of this Proposal, which include ratification, by more than half of the holders of PNA and PNB shares gathered at a special meeting ("AGESP PN"), pursuant to Art. 136, §1, of the Brazilian Corporate Law ("PN Classification"). Thus, in the context of the adoption of the measures for the implementation of the Migration to the Novo Mercado, the Company's management will timely provide for the convening of AGESP PN for the holders of PN shares to decide on the matter. Holders of PN shares who do not approve the PN Conversion in the aforementioned AGESP PN - whether by dissension, abstention or absence - will have the right to withdraw from the Company, upon reimbursement of the shares of which they are proven to be uninterrupted holders between the date of the material fact that announced the PN Conversion, on June 23, 2025, and the date of effective exercise of the right of withdrawal, pursuant to Art. 137, § 1, of the Brazilian Corporation Law. The criteria for calculating the reimbursement amount in the event of any exercise of the right of withdrawal are provided for in item 5 below. Finally, the Company notes that it reserves the right to convene a general meeting to ratify or reconsider the resolution, if the administrators believe that payment of the price of reimbursement of the PN shares to the dissenting shareholders who exercised the right of withdrawal will put the financial stability of the Company at risk, pursuant to Art. 137, §3, of the Brazilian Corporate Law. 2. Report the shares and classes to which the withdrawal applies The right of withdrawal will be applicable to shareholders holding PN shares who do not approve the PN Conversion in AGESP PN—whether by dissention, abstention or absence. 3. Inform the date of the first publication of the call notice of the meeting, as well as the date of communication of the relevant fact regarding the decision that gave or will give rise to the withdrawal The first Material Fact referring to the proposals that will give rise to the right of withdrawal was disclosed by the Company on June 23, 2025. The call notice of this Meeting was published, for the first time, on June 24, 2025. 4. Inform the deadline for exercising the right of withdrawal and the date that will be considered for the purpose of determining the holders of the shares that may exercise the right of withdrawal Uninterruptible holders of PN shares between the date of disclosure of the first Material Fact on the proposal of the PN Conversion (June 23, 2025), and the date of effective exercise of the right of withdrawal, pursuant to Art. 137, § 1, of the Corporations Act. Among such shareholders, holders of PN shares who do not vote favorably for the PN Conversion in the AGESP PN—whether by dissention, abstention or absence, may exercise the right to withdraw Pursuant to Art. 137 of the Corporations Law, the deadline for exercising the right of withdrawal, under penalty of forfeiture, will be up to 30 days from the date of publication of the minutes of the special meeting. 5. Report the amount of reimbursement per share or, if it is not possible to determine it in advance, the management estimate of this amount Pursuant to Article 107 of the Company's Bylaws, in the event of exercise of the right of withdrawal by shareholders holding PN shares, the reimbursement amount will correspond to the book equity value of the share, calculated based on the net equity contained in the last financial statements approved by the general meeting, ensuring the right to draw up the special balance sheet provided for in Art. 45 of the Corporation Law. Based on this criterion, the equity value of the Company's shares calculated based on the financial statements for the fiscal year ended December 31, 2024, adjusted based on the Net Equity divided by the number of outstanding shares, excluding shares in treasury, would correspond to R$ 8.6467556201 per share. 6. Inform how reimbursement is to be calculated The amount of the reimbursement will correspond to the book equity value of the share, calculated based on the net equity contained in the last financial statements approved by the general meeting, observing the provisions of item 5 above. 7. Inform whether shareholders will be entitled to request the withdrawal of the special balance sheet The right to draw up the special balance sheet provided for in art. 45 of the Brazilian Corporate Law will be guaranteed, in compliance with the provisions of item 5 above. 8. If reimbursement amount is determined by evaluation, list experts or specialist companies recommended by management Not applicable. 9. In the event of incorporation, incorporation of shares or merger involving controlling and controlled companies or under common control a) Calculate stock replacement relationships based on equity value at market prices or other criteria accepted by CVM b) Inform whether the relationships of substitution of the shares provided for in the operation protocol are less advantageous than those calculated in accordance with item 9 (a) above c) Report the reimbursement amount calculated based on the value of the equity at market prices or other criteria accepted by the CVM Not applicable. 10. Report the equity value of each share calculated according to the last approved balance sheet The equity value of the Company's shares calculated based on the financial statements for the fiscal year ended December 31, 2024, adjusted based on the Net Equity divided by the number of shares outstanding, excluding shares in treasury, would correspond to R$ 8.6467556201 per share.
