MATERIAL FACT

Sendas Distribuidora S.A. ("Company" or "Assaí"), pursuant to the Resolution of the Brazilian Securities Commission No. 44/21, informs its shareholders and the market in general that it has included new expectations related to the investments levels expected for the year 2026. The new guidance considers the current macroeconomic scenario and market expectations for next year.

As part of its strategy of continuing financial discipline and focusing on reducing leverage for 2026, the Company informs the new future expectation of investments of approximately R$ 700 million in the cash view and reiterates the expectation of opening 10 stores.

The Company reiterates the projections forecast for the year 2025: investments levels between R$ 1.0 and R$ 1.2 billion in the cash view and expectation of opening 10 stores.

The projections outlined above are valid until their effective realization or until new analyses and/or revisions are carried out by the Company's management that identify different indicators for the projections presented as a result of changes in the assumptions used, provided that the revision will be at least annual.

The above projections will be included in section 3 of the Reference Form and will be available in the Empresas.Net system, on the websites of the Brazilian Securities Commission (http://cvm.gov.br/) and the Company’s Investor Relations (https://ri.assai.com.br/) within the applicable period. Any changes in these estimates will be disclosed to the market by means of a Material Fact.

Information on business prospects, projections and targets are mere forecasts, based on management's current expectations, always subject to risks and uncertainties, and in no way constitute, guarantee or predict results. Such projections depend on market conditions in general, the Brazilian economic scenario and the sector in which the Company operates. Any changes in perception or in the factors described above may cause the actual results to differ from those provided for in the estimates presented herein, and the Company may revise them to higher or lower levels, in accordance with the new expectations. In the event of a material change in these factors, the above expectations will be revised.
