MATERIAL FACT
Braskem S.A. ("Braskem"
or "Company") (Ticker B3: BRKM3, BRKM5 and BRKM6; NYSE: BAK; LATIBEX: XBRK) in continuity with the Notices to the Market of
September 8, 2025 and November 19, 2025, hereby informs its shareholders and the market in general that Braskem Idesa S.A.P.I. ( together
with its subsidiaries and affiliates, “Braskem Idesa”) has provided certain holders and investment managers of one or more
of Braskem Idesa's outstanding 7.450% Senior Secured Notes due 2029 and 6.990% Senior Secured Notes due 2032 (“Investors”)
with certain non-public information relating to Braskem Idesa, in the context of a possible reorganization of its capital structure (“Restructuring”).
Under the
terms of the confidentiality agreements entered into on December 18, 2025, between Braskem Idesa and the Investors (collectively, the
“Confidentiality Agreements”), Braskem Idesa agreed to publicly disclose all material information provided to the Investors
(“Shared Information”) after the termination of the period established in the Confidentiality Agreements. The Shared Information
is publicly available on the Braskem Idesa and Braskem websites at the link “https://api.mziq.com/mzfilemanager/v2/d/540b55c5-af99-45f7-a772-92665eb948e9/a8f7a40c-ca07-0290-3d19-a36bae3f8a79?origin=2”,
and is provided to fulfill Braskem Idesa's obligations under the Confidentiality Agreements and in compliance with applicable legal rules.
Since the execution of
the Confidentiality Agreements, Braskem Idesa and the Investors, through their respective advisors, have prepared and exchanged the following
information:
| 1. | Discussion materials from Braskem
Idesa and proposed terms for a possible restructuring (“Braskem Idesa Proposal”); and |
| 2. | Terms proposed by Investors
for a possible Restructuring, dated January 6, 2026 (“Investor Proposal” and together with the Braskem Idesa Proposal, the
“Proposals”). |
During this period, representatives
and advisors from Braskem Idesa and the Investors participated in discussions and correspondence regarding the Proposals, including an
in-person meeting held on December 18, 2025 among representatives and advisors from Braskem Idesa and the Investors, with no agreement
reached between the parties regarding Braskem Idesa's Proposal. Subsequently, after receiving the Investors' Proposal, Braskem Idesa indicated
that it would not agree to the terms proposed in said proposal.
The information contained
in the Braskem Idesa Proposal is accurate as of the delivery date, has not been updated since the delivery date, and should not be used
for any other purpose.
A copy of the terms of
the Proposals is attached to this Material Fact. No agreement regarding any of the Proposals or any other transaction has been reached
to date.
The Braskem Idesa materials
contain projections regarding prices, supply, costs, production, and use of polyethylene and ethane, as well as Braskem Idesa's financial
indicators, up to 2033. The projections presented are hypothetical data and forecasts that reflect the current expectations of Braskem
Idesa's management and should not be interpreted as guarantees or promises of performance, being subject to risks and uncertainties associated
with the economic, regulatory, and competitive conditions of the markets in which Braskem Idesa operates, and may therefore differ materially
from the figures and results actually recorded by Braskem Idesa. The Company clarifies that the projections contained in the materials
and the Braskem Idesa Proposal should not be considered as guidance and were prepared in the context of negotiations with Investors.
Braskem will keep the market
informed of any material developments on this matter, in compliance with applicable laws.

This Material Fact may contain forward-looking statements. These statements are not historical facts, but rather are based on the current
view and estimates of the Company's management regarding future economic and other circumstances, industry conditions, financial performance
and results, including any potential or projected impact regarding the geological event in Alagoas and related legal procedures on the
Company's business, financial condition and operating results. The words “project,” “believe,” “estimate,”
“expect,” “plan”, “objective” and other similar expressions, when referring to the Company, are used
to identify forward-looking statements. Statements related to the possible outcome of legal and administrative proceedings, implementation
of operational and financing strategies and investment plans, guidance on future operations, the objective of expanding its efforts to

or operating results of the Company are examples of forward-looking statements. Such statements reflect the current views of the Company's
management and are subject to various risks and uncertainties, many of which are beyond the Company’s control. There is no guarantee
that the events, trends or expected results will actually occur. The statements are based on various assumptions and factors, including,
but not limited to, general economic and market conditions, industry conditions and operating factors, availability, development and financial
access to new technologies. Any change in these assumptions or factors, including the projected impact from the joint venture and its
development of technologies, from the geological event in Alagoas and related legal procedures and the unprecedented impact on businesses,
employees, service providers, shareholders, investors and other stakeholders of the Company could cause effective results to differ significantly
from current expectations. For a comprehensive description of the risks and other factors that could impact any forward-looking statements
in this document, especially the factors discussed in the sections, see the reports filed with the Brazilian Securities and Exchange Commission
(CVM). This Material Fact does not constitute any offer of securities for sale in Brazil. No securities may be offered or sold in Brazil
