MATERIAL FACT
Braskem S.A. (“Braskem”
or “Company”) (Ticker B3: BRKM3, BRKM5 and BRKM6; NYSE: BAK; LATIBEX: XBRK), further to the Material Fact of September 26,
2025 and June 25, 2026, hereby informs its shareholders and the market in general that it has provided certain holders and investment
managers of one or more of senior securities and debenture holders issued or guaranteed by Braskem (“Investors”) with certain
non-public information relating to Braskem and its subsidiaries (“Shared Information”), in the context of a possible reorganization
of its capital structure (“Restructuring”).
Under the
terms of the confidentiality agreements entered into on June 11, 2026, between Braskem and the Investors (collectively, the “Confidentiality
Agreements”), Braskem agreed to publicly disclose all material information provided to the Investors after the termination of the
period established in the Confidentiality Agreements. The Shared Information is publicly available on the Braskem website at the link,
and is provided to fulfill Braskem’s obligations under the Confidentiality Agreements and in compliance with applicable legal rules.
Since the execution of
the Confidentiality Agreements, Braskem and the Investors, through their respective advisors, have prepared and exchanged the following
information:
| 1. | Discussion materials from Braskem
and proposed terms for a possible restructuring (“Braskem Proposal”); |
| 2. | Terms proposed by Investors
for the structure of the process and framework rules to negotiate a possible Restructuring, dated June 19, 2026 (the “Investors’
Proposal”); and |
| 3. | The Company’s response
to the Investor Proposal dated June 24, 2026 (together with Braskem Proposal and the Investors’ Proposal, the “Proposals”). |
During this period, representatives
and advisors from Braskem and the Investors participated in discussions and correspondence regarding the Proposals, including an in-person
meeting held on June 11, 2026 among representatives and advisors from Braskem and the Investors, with no agreement reached between the
parties regarding Braskem Proposal.
Given the short-term needs
of the Company and the Company’s interest in negotiating a Restructuring under a stable environment, during that in-person meeting
the Company requested the Investors to prioritize discussions on the process and framework rules to negotiate the terms of the Restructuring
under the stable and protected environment provided by an extrajudicial reorganization proceeding in Brazil and, accordingly, requested
to the Investors to provide a response with respect to the Company’s proposed process and framework rules on an expedited basis,
by the beginning of the week following the June 11 meeting. The Investor Proposal with such response was received by the Company six business
days after the meeting and in terms unacceptable to the Company. Therefore, Braskem indicated that it would not agree to the Investor
Proposal.
The Company reassured the
Investors that it is fully committed to continue discussions with its financial creditors in finding a consensual, structured, and orderly
solution for its capital structure that ensures the continuance of its operations in the ordinary course of business.
The information contained
in the Braskem 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 are available on the Braskem website at the link. No agreement regarding
any of the Proposals or any other transaction has been reached to date.
The Braskem Proposal contain
projections regarding prices, supply, sales volume, consumption and feedstock supply, costs, production and utilization rate, as well
as Braskem's financial indicators, up to 2035. The projections presented are hypothetical data and forecasts that reflect the current
expectations of Braskem'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 operates, and may therefore
differ materially from the figures and results actually recorded by Braskem. The Company clarifies that the projections contained in the
materials and the Braskem Proposal should not be considered as guidance and were prepared in the context of negotiations with Investors.
The Company clarifies that
the projections contained in Braskem's Shared Information should not be considered as guidance and were prepared in the context of the
Restructuring.
Braskem will keep the market
informed of any material developments on this matter, in compliance with applicable laws.
