Re.: Request for clarification regarding news – CVM Proceeding No. 19957.004980/2026-96

Dear Sirs,

In response to Official Letter No. 136/2026/CVM/SEP/GEA-1 (“Official Letter”), dated April 7, 2026, please find below Braskem S.A.’s (“Braskem” or the “Company”) clarifications regarding the news item published on the O Estado de São Paulo newspaper, Broadcast column, which contains the following statements:

“Dear Director,

We refer to the news item published today in the O Estado de São Paulo newspaper, in the Broadcast column, which contains the following statements:

Braskem drops on potential request for bankruptcy protection by subsidiary

Braskem’s shares closed down 7.99% yesterday, the worst performance on the Ibovespa. Braskem Idesa, its subsidiary in Mexico, is preparing to file for judicial reorganization, which could trigger clauses that pressure the parent company to also restructure its debt.”

As informed by the Company in the Notice to the Market released on August 28, 2025, the Company and its subsidiary Braskem Idesa S.A.P.I. (“Braskem Idesa”) are assessing different alternatives and measures to address the current challenges related to Braskem Idesa’s capital structure, arising in particular from conditions in the global petrochemical industry and from exogenous factors with significant impacts on Braskem Idesa.

In this context, as informed by the Company in the Notice to the Market released on September 8, 2025, and in the Material Fact disclosed on January 12, 2026, Braskem Idesa has engaged specialized financial and legal advisors to support it in evaluating such alternatives and has also entered into discussions with representatives of an ad hoc group of its creditors, seeking to achieve a sustainable capital structure for the company while preserving its operations.

Additionally, as informed by the Company in the Notices to the Market released on November 19, 2025, and February 20, 2026, Braskem Idesa announced the non-payment of interest scheduled for November 18, 2025, and February 20, 2026, relating, respectively, to its secured senior notes due in 2029 and 2032.

The assessments and discussions with Braskem Idesa’s ad hoc group of creditors remain ongoing, with a view to reorganizing its capital structure, including the assessment of potential protective measures. Nevertheless, we clarify that, as of this date, there is no decision as to which alternative (or set of alternatives) will be implemented.

Finally, as informed by the Company in its financial statements for the year ended 2025, disclosed on March 26, 2026, the adoption of any measures by Braskem Idesa may have impacts on the Company and on the shareholder control of Braskem Idesa.

Being what we had to clarify, we made ourselves available to you for any additional clarifications regarding the topic, if necessary.

São Paulo, April 8, 2026.

Chief Financial and Investor Relations Officer
