These shares were formed from the consolidation of share fractions resulting from the reverse stock split of all common shares issued by the Company, at a ratio of 40 (forty) shares to 1 (one) share, followed by a forward stock split, where 1 (one) consolidated share became equivalent to 80 (eighty) shares. This operation did not change the Company’s share capital, only the total number of shares, as approved by shareholders at the Extraordinary General Meeting held on March 13, 2025 (“Transaction”), and was conducted through Itaú Corretora de Valores S.A. on B3 S.A. – Brasil, Bolsa, Balcão (“B3”).

The auction proceeds, totaling R$949,354,168.17 (nine hundred forty-nine million, three hundred fifty-four thousand, one hundred sixty-eight reais and seventeen cents), net of costs and fees, equivalent to R$ 26.64196300439 per common share, will be made available to the holders of the share fractions, in proportion to their holdings, by May 28, 2025, as follows:

(a) Shareholders with complete registration data: the amounts will be deposited into the checking account indicated in the respective shareholder’s registration;

(b) Shareholders with shares held in B3’s Central Depository: the amounts will be credited directly to the Central Depository, which will be responsible for transferring them to the respective shareholder through their custodian agent; and

(c) Other shareholders not identified or with incomplete registration data: the amounts will be held by the Company, within the legal timeframe, for collection by the respective holder upon submission of complete registration information.

Amounts allocated to investors (both residents and non-residents) may be subject to income tax on any capital gains, which will be taxed as “net gains” in accordance with current legislation. Therefore, shareholders and their advisors are responsible for determining the appropriate tax treatment.

Pursuant to the requirements of the Securities Exchange Act of 1934, the registrant has duly caused this report to be signed on its behalf by the undersigned, thereunto duly authorized.
