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

Dear Sirs,

In response to Official Letter No. 129/2026/CVM/SEP/GEA-1 (“Official Letter”), attached to this reply, Braskem S.A. (“Braskem” or the “Company”) would like to provide the following clarifications regarding the news item published by Exame Online, under the title: “Crisis leads Braskem to consider judicial reorganization, agency says,” which contains the following statements:

“According to sources heard by Bloomberg, Braskem is considering resorting to judicial reorganization or other creditor protection mechanisms amid its debt. The measure, under review by the management, seeks to preserve cash and reorganize obligations at a time when the company faces difficulties in meeting future commitments to creditors.

Sources close to the discussions stated that the company is considering both the filing for precautionary protection—a temporary instrument in Brazil—and broader alternatives, including a potential judicial reorganization.”

As disclosed by the Company in the Material Facts notice dated September 26, 2025, the Company engaged specialized financial and legal advisors to assist in preparing a comprehensive assessment of economic and financial alternatives to optimize its capital structure.

Such assessment is still ongoing, and the Company and its advisors have been making structured progress in the formulation of a comprehensive plan to restructure its capital structure, as well as in negotiations with the creditors’ advisors, as reported in its financial statements for the fiscal year ended 2025, released on March 26, 2026.

In the course of the work related to such assessment, the Company and its advisors are considering different alternatives, including potential creditor protection measures. Notwithstanding, we clarify that, as of this date, there is no decision regarding which alternative (or set of alternatives) to be implemented.

We remain available to provide any additional clarifications.

Sincerely,

Felipe Montoro Jens

Chief Financial and Investor Relations Officer
