Companhia Paranaense de Energia - COPEL, a company that generates, transmits, distributes and sells power, with shares listed on B3 (CPLE3, CPLE5, CPLE6), the NYSE (ELPVY, ELP) and LATIBEX (XCOP), hereby discloses to its shareholders and the market in general that:

1.       The Company's Board of Directors (“CAD”) was informed of the result of the independent internal investigation work, conducted by the “Special Committee”, created in December 2019, to investigate alleged irregularities originating substantially between 2015 and 2018, which involved its subsidiary Copel Telecomunicações SA (“Copel Telecom”);

2. The “Special Committee” had the participation of members of the Statutory Audit Committee and the CAD, as well as the participation of an independent ad hoc external member, with the support of external legal and forensic advisors hired, respectively, Stocche Forbes Advogados and Control Risks;

3. The alleged irregularities that could have injured Copel Telecom, were basically related to the processes of contracting service providers and waiving revenues related to some customers and suppliers;

4. The aforementioned irregularities were identified, mainly, through reports from the Company's Whistleblowing Channel and internal control work, which were initially the object of analysis and verification by the Internal Audit. As a result, an action plan has already started to be implemented, with the objective of continuing to strengthen corporate governance and adapt Copel Telecom's systems, processes and controls.

5. The Paraná State Audit Court (“TCE-PR”) and the Paraná Public Prosecutor's Office were formally communicated. Thus, these facts were also subject to analysis by the TCE-PR resulting in the availability of reports to the Company's Management at the end of 2019;

6. Considering the internal findings and reports made available by the TCE-PR, the CAD determined the creation of the referred “Special Committee”;

7. The work carried out identified deficiencies in controls and opportunities for improvements in customer, supply and supplier management processes at Copel Telecom. However, there was no evidence of accounting fraud and / or intentional error, nor was there evidence of receipt or payment of an improper advantage involving employees;

8. Consequently, there are no elements or indications that the amounts in the Company's consolidated financial statements may be materially affected;

9. Based on the results of the work carried out, the CAD decided: (i) to prepare a plan for remediation, repair and continued collaboration with the authorities and, as a result, (ii) the closure of the Special Investigation Committee.
