INSTRUCTIONS FOR PARTICIPATION THROUGH ABSENTEE BALLOT

Pursuant to CVM Instruction 481, the Company will adopt the absentee voting system at this Annual Shareholders Meeting. As such, starting today, shareholders with voting rights can submit their voting instructions regarding the items on the agenda: (i) to qualified service providers; or (ii) directly to the Company, as described below:

(i) Voting through service providers

Bookkeeping services for ISA CTEEP's shares are provided by Itaú Corretora de Valores S.A. Shareholders whose shares are not held at the central depository can send their absentee ballot instructions through Banco Itaú, for which they must: (i) register at the Itaú Securities Services Assembleia Digital website; (ii) have a digital certificate (public or private) and, in case of legal entities; (iii) submit documents and proxy as evidence of voting powers. Other questions regarding the use of the system should be clarified with Banco Itaú.

Banco Itaúhttps://assembleiadigital.comprova.com/itausecuritiesservices/artigo/home/assembleia-digital 3003-9285 (state capitals and metropolitan areas) 0800 7209285 (other locations).

(ii) Submission of Absentee Ballot directly to the Company

Shareholders can exercise their absentee voting right directly at ISA CTEEP, for which they must send the following documents by email [e-mail]: (i) scanned Absentee Ballot Form duly completed; (ii) scanned copy of identity document; and (iii) proof of share ownership.

Absentee Ballots must be sent to ISA CTEEP up to 7 days prior to the date of the Shareholders Meeting.

Within 3 days after receiving the absentee ballot, ISA CTEEP shall inform the shareholder: (i) the receipt of the absentee ballot and whether the ballot and accompanying documents are sufficient for the shareholder's vote to be considered valid; or (ii) the need to rectify or resend the absentee ballot or accompanying documents, describing the necessary procedures and deadlines to regularize the absentee vote cast.

Absentee Ballots that do not meet the above specifications and are not rectified will not be considered valid and, consequently, the votes contained therein will not be counted.

During the voting period, shareholders may change their voting instructions such that the last voting instruction received by the Company is considered valid, provided it meets the requirements for submission of the necessary documents and the deadline for receipt. After the end of the voting period, shareholders cannot change the Voting Instructions sent already. Shareholders must attend the Shareholders Meeting in person if they consider it necessary to change the vote already cast.

In case of discrepancy between the Absentee Ballot sent directly to the Company and the Voting Instruction contained in the consolidated voting map sent by the stock transfer agent for the same Individual Taxpayer ID (CPF) or Corporate Taxpayer ID (CNPJ), the Voting Instruction received by the stock transfer agent shall prevail, in accordance with CVM Instruction 481.

Procedures for sending absentee ballots to the Custody Agent must be obtained from the respective agent.
