NOTICE TO MARKET
SENDAS DISTRIBUIDORA S.A. (“Company”
or “Assaí”), in continuation of the Material Fact disclosed by
the Company on September 24, 2025 (“Material Fact 24.9.25”) and in
view of the Material Fact disclosed today by Companhia Brasileira de Distribuição (“GPA”),
hereby communicates and clarifies the following:
1. As previously disclosed by the Company, there is an ongoing precautionary judicial measure with a
request for an injunction (“Precautionary Measure”) and an arbitration
proceeding initiated by Assaí against GPA and Casino Guichard Perrachon S.A. and Segisor (jointly, “Casino”),
aimed at holding GPA and Casino responsible and requiring them to provide guarantees for GPA’s tax contingencies prior to the spin-off
completed on December 31, 2020, since tax authorities have been seeking to attribute joint liability to Assaí for such GPA tax contingencies
that are still under discussion
2. On December 12, 2025, the judge of the 3rd Business Court of the State of São Paulo
issued a decision denying the request for urgent relief made by Assaí in the Precautionary Measure. This first instance decision,
which is subject to appeal, was rendered in view of the fact that GPA had secured the tax contingencies that were, up to that point,
being claimed against Assaí, including the Administrative Procedure for Recognition of Liability (PARR), in the approximate amount
of R$ 36 million, as mentioned in the Material Fact of September 24, 2025.
3. The judicial precautionary measure and the arbitration proceedings initiated by Assaí against
Casino and GPA are still ongoing, with the aim of safeguarding Assaí’s rights and ensuring, pursuant to the Separation Agreement,
the proper allocation of responsibilities and obligations among the parties, including with respect to the provision of guarantees and
indemnification for any liabilities that are not Assaí’s responsibility.
4.
Assaí reiterates its firm conviction that it does not have any responsibility, whether direct or joint, for tax liabilities belonging
to GPA, a position supported by solid legal grounds and independent legal opinions of recognized reputation. Assaí will continue
to take all appropriate measures, in the judicial, arbitral, or administrative spheres, including before the competent tax authorities,
to safeguard its rights and definitively prevent any attempt to attribute to it a liability that does not pertain to it.
