Attn: Superintendence of Corporate

Ref.: Request for clarification
on news - CVM Process no. 19957. 016584/2025-21
Dear Sirs,
We refer to Official
Letter No. 304/2025/CVM/SEP/GEA-1 ("Official Letter"), dated November 11, 2025, through which you request clarifications from
Braskem S.A. ("Braskem" or "Company"), as follows:
"Mr.
Director,
We refer to
the news published on this date in the Exame Online media, News section, under the title: "Novonor negotiates sale of control of
Braskem", which contains the following statements:
Novonor,
the parent company of Braskem (BRKM5), is close to concluding an agreement to sell its majority stake in the petrochemical company to
IG4 Capital, according to sources heard by the American website Bloomberg. The fund would share control of the company with Petrobras
(PETR3; PETR4).
[...]
The
new control of the company would be assumed by IG4 after approval of the deal by Cade, the Brazilian antitrust body. The expectation is
that a final agreement will be reached this week. However, talks are ongoing and the outcome still depends on adjustments.
To
reduce losses and maintain some influence in the company, Novonor is trying to preserve a residual slice of between 4% and 5% in the corporate
structure, according to people with direct knowledge of the matter.
In view of
the above, we request that you clarify whether the news is true and, if so, explain the reasons why you consider it not to be a relevant
fact, as well as comment on other information considered important on the subject."
In this regard,
Braskem would like to reiterate that it is not responsible for and does not conduct any negotiations by its shareholder, Novonor S.A.
- Em Recuperação Judicial ("Controlling Shareholder"), on the potential sale of the Company's controlling stake,
nor on any negotiations by Novonor S.A. - Em Recuperação Judicial's creditor banks. In this regard, the Company clarifies
that it is not aware of the information contained in this report, which is why it requested clarification from its Controlling Shareholder,
who informed it as follows:
1
"In response
to the clarifications requested, Novonor informs that, to date, there have been no material or binding developments in the discussions
it has been holding with interested parties involving its indirect stake in Braskem S.A.
Any material
developments in the discussions will be immediately communicated to the Company so that it can adopt the usual measures."
That's all we
have to say, and we remain at your disposal for any further clarification on the subject, should they be necessary.
São Paulo, November 11, 2025.
Felipe Montoro Jens
Chief Financial and Investor Relations
Officer
Braskem S.A.
