Att.: Superintendent of Company Relations - SEP
Ref.: Request for clarification regarding news
– CVM Process nº 19957.013591/2025-71
Dear Sirs,
We refer to Official Letter nº
255/2025/CVM/SEP/GEA-1 ("Official Letter"), dated October 6, 2025, through which you request clarifications from Braskem S.A.
("Braskem" or "Company"), as detailed below:
“Mr. Director,
1. We refer to the news
published today in O Estado de São Paulo, Economy & Business section, under the title: “IG4 wants to take over Braskem
in 60 days and banks do not rule out executing guarantee", which contains the following statements:
The creditor banks of Novonor, which
controls Braskem, are willing to become shareholders and take control of the petrochemical company in the next 60 days, alongside Petrobras.
The Column found that the movement can be carried out even without consensus with Novonor, that is, they do not rule out taking over the
shares, which were given as collateral for loans to the former Odebrecht.
2. In view of the above, we require you
to clarify whether the news is true and, if so, explain the reasons why it was understood that it is not a Material Fact, in addition
to commenting on other information considered important on the matter.”
In this regard, Braskem would like
to reiterate that it is not responsible for nor conducts any negotiations by its shareholders, Novonor S.A. – In Judicial Recovery
and Petrobras S.A. (“Shareholders”), regarding the potential sale of controlling interest in the Company, nor about possible
negotiations by the creditor banks of Novonor S.A. – In Judicial Recovery. In this sense, the Company clarifies that it is not aware
of the information contained in such news, which is why it requested clarifications from its Shareholders, who informed the following:
“We received with surprise any mention of a hostile
takeover of control of Braskem alongside Petrobras. We also inform that, to date, there has been no material evolution in the discussions
it has been holding with interested parties involving its indirect participation in Braskem S.A.”
1

“The company clarifies that Petrobras does not participate
in negotiations between Novonor, banks and IG4. Petrobras reiterates that no decision has been made regarding its participation in Braskem
and continues to study alternatives.”
Being what we had to clarify, we
made ourselves available to you for any additional clarifications regarding the topic, if necessary.
São Paulo, October 7, 2025.

Chief Financial and Investor Relations Officer
Braskem S.A.
