In view of this, in order to attend B3's requirement, the Company informs that it will submit to its Board of Directors, proposal for a reverse split of its common and preferred shares, in a ratio to be evaluated, for shareholder deliberation at an Extraordinary General Meeting, to be called and held in conjunction with its General Annual Meeting, on April 29, 2024.

Dear Ma'am,

We refer to Official Letter 1134/2023-SLS, sent on September 27, 2023, which established the deadline of March 27, 2024 for the Company to take the appropriate measures to meet the requirement set out in art. 46 of the Issuers' Regulation ("Regulation"), which determines that the price of securities admitted to trading on B3 must be maintained at a value equal to or greater than R$1.00 per unit.

In view of the requests for suspension and, alternatively, extension of the deadline presented on February, 29, 2024, we inform the partial approval of the claim, in such a way that the deadline for compliance, provided for in Official Letter 1134/2023-SLS, is extended until April 30, 2024, with the aim of enabling the Company to adopt the appropriate measures to place the price of its securities above R$ 1.00.

If the appropriate measures are not taken within the period abovementioned, B3 may, without prejudice to any enforcement procedure, determine non-continuous trading of the aforementioned securities, as provided in art. 50 of the Regulation.

Finally, in order to provide the necessary clarifications to the market, the Company must disclose the content of this letter by March 18, 2024.
