MATERIAL FACT
Braskem S.A. (B3 Ticker:
BRKM3, BRKM5, and BRKM6; NYSE: BAK; LATIBEX: XBRK) (“Braskem” or the “Company”), further to the Material Facts
dated September 26, 2025, June 25 and 26, 2026 and as of today, hereby notifies its shareholders and the market in general that it has
filed, on this date, together with certain subsidiaries (collectively with the Company, the “Debtors”), a petition for extrajudicial
reorganization (“Extrajudicial Reorganization”), filed with the 2nd Bankruptcy and Judicial Reorganization Court of the Judicial
District of the Capital of the State of São Paulo (2ª Vara de Falências e Recuperações Judiciais da
Comarca da Capital do Estado de São Paulo), pursuant to Law 11,101/05, with the objective of ensuring a stable, protected,
and appropriate legal environment for negotiating and implementing the restructuring of its unsecured financial obligations in the approximate
amount of US$ 10.9 billion (“Subject Claims”).
The Company
has secured the participation in the extrajudicial reorganization plan that was filed (the “Plan”) of unsecured creditors
who, collectively, represent 39.6% of the Subject Claims (“Signatory Creditors”), a percentage sufficient to file the referred
petition. Pursuant to applicable law, the Company has 90 days from the filing of the Extrajudicial Reorganization petition to obtain the
minimum percentage required for approval of its updated Extrajudicial Reorganization Plan (“Updated Plan”), thereby ensuring
that 100% of the Subject Claims are bound by the new terms and conditions of payment to be defined in the Updated Plan. The Plan is publicly
available at Braskem’s site in https://api.mziq.com/mzfilemanager/v2/d/540b55c5-af99-45f7-a772-92665eb948e9/1f8bcb17-45b3-8cbd-2e84-ade239596ea2?origin=2.
The Plan establishes,
among other things, the general parameters that will form the basis for negotiations between the Debtors, their main shareholders, and
their financial creditors of the terms and conditions of an Updated Plan, to be presented within the next 90 days, based on principles
of burden sharing among all the relevant stakeholders and a sustainable capital structure and balance sheet of the Debtors. Those parameters
include, among others, (i) an amendment and extension of the obligations and maturities of the Subject Claims, including capitalization
of interest for a period to be defined (relief period), considering the Company’s operational turnaround and the Debtors’
capital and liquidity needs, alongside compensation to creditors for providing such extension and relief, including through economics
and credit enhancements of the Subject Claims as well as reporting and oversight to be agreed; (ii) potential liquidity support from
the Company’s main shareholders during the relief period, if necessary, subject to their approvals required under the applicable
governance; (iii) a commitment by the main shareholders or third parties (to the extent agreed by the Debtors, the main shareholders,
and the Signatory Creditors), to contribute or backstop equity capital to the Debtors at the end of the relief period or such other date
to be agreed, subject to their approvals required under the applicable governance, should the Company fail to meet certain metrics to
be negotiated; and (iv) possible equitization of a portion of the Subject Claims at the end of the relief period or other date as agreed.
In addition, the Plan establishes
certain milestones to be met during the negotiation of the Updated Plan, as well as certain rights to early terminate the Plan for the
benefit of the Signatory Creditors.
The terms, conditions and
deadlines of the aforementioned and other parameters to be included in the Updated Plan, are subject to the negotiation and agreement
by the Company, its main shareholders and the Signatory Creditors, and their approvals required under the applicable governance.
The filing of the petition
for Extrajudicial Reorganization made today takes effect immediately and suspends the enforceability of the Debtors’ obligations
with respect to the Subject Claims.
The Plan represents a significant
step for the Company towards the long-term sustainability of the Debtors’ capital structure and reflects the shared goal of the
Company and its key stakeholders to achieve a consensual restructuring in accordance with the negotiation framework agreed with the Signatory
Creditors. The Plan has the support of Shine I Fundo de Investimento em Participações de Responsabilidade Limitada and Petróleo
Brasileiro S.A. – Petrobras, the Company’s main shareholders.
Braskem clarifies that
the Extrajudicial Reorganization has a limited, strictly financial scope and does not cover any of the Company’s obligations to
its suppliers, customers, and other stakeholders, which remain in effect and continue to be fulfilled as usual, in accordance with the
terms of the respective contracts.
Braskem will
keep the market informed of relevant developments, in compliance with applicable laws, and will make the relevant documents available
on its investor relations website (www.braskem-ri.com.br) and on the websites of the CVM (www.cvm.gov.br)
and B3 (www.b3.com.br), as required by applicable regulations.
