Ref .: Request for clarification on atypical oscillation

Dear Sir,

In view of the latest fluctuations recorded with the securities issued by this company, the number of trades and the amount traded, as shown below, we ask to be informed, by 06/21/2021, if there is any fact known to you by V.S.a. that can justify them.

 * Updated until 5:00 pm.

** Note: the CPLE5 share had its last trade on 05/22/2020.

____________________________________________________

In response to the request, it is clarified that the fluctuation mentioned in the Official Letter involved the trading of 500 class “A” preferred shares issued by the Company (“PNA”) traded under the code CPLE5. Today, PNA shares correspond to 0.11% of the total shares issued by Copel. Since they represent a small fraction of the capital, the average volume of trades (“ADTV”) involving PNA shares is quite low, so much so that in many sessions, there is not even PNA shares trading. Thus, sporadic trades involving PNA shares end up affecting the price in an atypical way.

The Company does not know the reason for carrying out the negotiations in question, as well as any material information not disclosed to the market that may have been used in the decision of investors to trade the PNA shares that are being questioned.

Curitiba, June 21, 2021.
