The Debentures will be subject to public distribution under the automatic registration regime, with the intermediation of institutions that are part of the securities distribution system, pursuant to CVM Resolution No. 160, of July 13, 2022, as amended (“Offering”).

On the Unit Par Value or the balance of the Unit Par Value of the Debentures, as the case may be, remunerative interest will accrue corresponding to the accumulated variation of 100% (one hundred percent) of the daily average rates of the Interbank Deposit (DI) for one day, over extra-group, expressed as an annual percentage, based on 252 (two hundred and fifty-two) business days, calculated and disclosed daily by B3 S.A. – Brasil, Bolsa, Balcão (“B3”), plus a surcharge (spread) of 1.20% (one point twenty percent) per year, based on 252 (two hundred and fifty-two) business days.

The net proceeds raised through the Offering will be used by the Company as part of the payment for the early redemption of all simple debentures, not convertible into shares, unsecured, in a single series, of the Company’s 4th (fourth) issuance, issued under the “Instrumento Particular de Escritura da 4ª (Quarta) Emissão de Debêntures Simples, não Conversíveis em Ações, da Espécie Quirografária, em Série Única, para Distribuição Pública com Esforços Restritos, da Sendas Distribuidora S.A.” initially executed on November 26, 2021 (as amended from time to time), whose trading code is ASAI14.

The minutes of the Board of Directors’ Meeting that approved the terms and conditions of the Issuance, as well as further information regarding the Issuance and the Offering, can be obtained in the Deed of Issuance and the Offering Notice available for consultation on the Company’s investor relations website (https://ri.assai.com.br/) and on the websites of the CVM (https://cvm.gov.br) and B3 (https://b3.com.br).

This Material Fact is for informational purposes only, in accordance with current regulations, and does not constitute nor should it be interpreted as any effort to sell the Debentures.

The Company will keep its shareholders and the market in general informed about any new relevant developments related to the Issuance.
