Ref.: Requestfor clarification regarding news report- CVM Proceeding No. 19957.012863/2026-04

Dear Sir/Madam,

We refer to Official Letter 231/2026/CVM/SEP/GEA-1 “Official Letter”), dated July 27, 2026, through which you requested clarifications from Braskem S.A. ("Braskem" or "Company"), as detailed below:

“Dear Director,

We refer to the news article publishedon this date in the newspaper O Estado de S. Paulo, News section, under the headline: " Near the court-imposed deadline, the deadlockbetween Braskem and its creditors continues", which includes the following statements:

[...]

The providing of capital, of course,requires consideration: they are requesting that all of the Company's assets be pledged as collateral.

[...]

In view of the above, we request thatyou clarify whether the news is true and, if so, explain the reasons why it was not considered a material fact, as well as comment onany additional information deemed relevant on the matter.”

As disclosed in the Material Fact published on September 26, 2025, the Company retained specialized financial and legal advisors to assist it in conducting a comprehensive assessment of economic and financial alternatives aimed at optimizing its capital structure.

As disclosed in the Material Fact published on June 25, 2026, the Company and certain holders of, and investment managers for, one or more of the Senior Notes and Debentures issued or guaranteed by Braskem (“Investors”), together with their respective advisors, have been exchanging information and non-binding, indicative proposals regarding terms and conditions in the context of a potential reorganization of the Company’s capital structure (“Restructuring”).

In addition, as disclosed in the Material Facts published on June 25 and 26, 2026, the Court of 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 daComarca da Capital do Estado de São Paulo), within the scope of the Precautionary Injunctive Relief proceeding (Tutela deUrgência Cautelar), filed by the Company and certain of its subsidiaries, has granted the requests, among other measures, order the stay of all enforcement actions and attachments by creditors that have been invited to participate in the mediation proceeding initiated by the Company and certain of its subsidiaries before the Wind Mediation Chamber (Câmara Wind de Mediação), with such stay remaining in effect for a period of 60 days.

Since then, and as clarified in the response to B3 Letter No. 219/2026-SLE disclosed by the Company in its Notice to the Market dated July 21, 2026, the Company and its advisors have continued to engage with creditors and their advisors, having received merely indicative and non-binding proposals from groups of creditors regarding the key terms and tentative parameters for a potential Restructuring. Such proposals include a possible capitalization and the granting of security interests over assets, which remain under analysis by the Company. As of this date, no decision has been reached regarding the terms of a potential Restructuring.

The Company reiterates to its Investors that it remains fully committed to continuing discussions with its financial creditors in pursuit of a consensual, structural and orderly solution for its capital structure, while ensuring the continuity of its operations in the ordinary course of business.

There being no further matters to address at this time, we remain at disposal for any further clarification that may be required.
