81. Shareholders may exercise their voting rights through: (i) remote voting ballot, with the sending of voting instructions prior to the AGM ("Ballot"); or, (ii) participation via electronic system through Ten Meetings platform at the time of the AGM.

To participate in the AGM through the electronic platform, shareholders must register on the digital platform and send the necessary documents, pursuant to item 1 of the Shareholders' Participation Manual, through the electronic address of the digital platform https://assembleia.ten.com.br/869153752up to 48 (forty-eight) hours before the AGM, that is, until 4 p.m. on April 28, 2024, and must observe the detailed instructions in the Platform Manual - Participant, of the Ten Meetings platform, also available for download at the above electronic address.

Any shareholder may appoint an attorney-in-fact to participate in the AGM and vote on their behalf. In the event of representation, the shareholder must observe the terms of article 126 of Law No. 6,404, of December 15, 1976, as amended ("Corporations Law"),

and the attorney-in-fact must have been appointed less than 1 (one) year before and be a shareholder, a Company administrator or a lawyer, or, also, be a financial institution.

The shareholder that chooses to exercise their right to vote through the remote voting ballot must send the corresponding Ballot by April 23, 2024, including, through their respective custody agent, by the share bookkeeping bank of the Company or directly to the Company, through the electronic address ri@light.com.br.

Shareholders that choose to exercise their right to vote remotely through service providers must contact their custody agent or the Company's share bookkeeping institution, depending on whether or not their shares are deposited in a central depositary, subject to the rules determined by them for the transmission of their voting instructions, as well as the deadlines necessary for their votes to be transmitted.

We emphasize that, in the event of discrepancy between the remote voting ballot received directly by the Company and the voting instructions eventually sent to the custodian agents or to the bookkeeper of the Company's shares, the latter will prevail.

The sending of the physical copy of the Ballot to the Company's principal place of business is waived, as well as the notarization and authentications. It suffices to send a simple copy of the original counterparts to the electronic address ri@light.com.br. The shareholder will be responsible for the integrity and reliability of the documents sent to the Company.
