Re.: B3 OFFICIAL LETTER 122/2026-SLE DATED MAY 15, 2026 – BRASKEM – REQUEST FOR CLARIFICATION REGARDING NEWS PUBLISHED IN THE MEDIA

Dear Sirs,

We refer to B3 Official Letter No. 122/2026-SLE ("Letter"), dated May 15, 2026, through which you requested clarifications from Braskem S.A. ("Braskem" or "Company"), as follows:

“Re.: Request for clarification regarding news published in the media

Dear Sir,

In an article published by Valor Econômico - Pipeline on May 15, 2026, under the title “Without agreement with Slim, Braskem subsidiary may file for judicial reorganization in the U.S.”, it was reported, among other information, that:

Braskem Idesa, Braskem’s subsidiary in Mexico, is expected to file for judicial reorganization in the United States (Chapter 11) even before asset manager IG4 takes over the petrochemical company, according to Pipeline.

The initial idea was to carry out a broader restructuring of the holding company’s debt, but now this should begin with the debt in Mexico. Braskem Idesa had been negotiating with holders of the 2029 and 2032 bonds to reschedule payments and reduce financial leverage, which stood at 40.31x in March. This group of investors holds most of the company’s debt, totaling US$2 billion in securities.

The creditor of these bonds is businessman Carlos Slim, who is a shareholder of Inbrusa, which owns 25% of Idesa. With more than 50% of the securities, Slim is said to be interested in increasing his stake in the company through a potential debt-to-equity swap, but no consensus was reached.

Discussions with the other bondholders are more advanced. Therefore, the most likely path is a Chapter 11 filing in the United States, as Slim would not be able to vote due to a conflict of interest, as he is also a shareholder.

Braskem Idesa is seeking DIP (Debtor-in-Possession) financing, which may involve the participation of bondholders as well as the Braskem holding. The company in Mexico has been in default on interest payments for the 2029 notes since November and did not pay the interest due on the 2032 notes in February.

Filing for Chapter 11 in the United States should not accelerate Braskem’s debt. “There is no cross-default clause with Braskem’s debt,” says Roger Horn, senior credit strategist for emerging markets at Mariva Capital Markets.

However, the Braskem holding supported a loan taken by its subsidiary in Mexico to build an ethane import terminal in the country, through the subsidiary Terminal Químico Puerto México (TQPM). If this debt is called by creditors, it could impact the holding company.

Braskem Idesa, which produces polyethylene at its plant in Veracruz, Mexico, has been operating below installed capacity due to lower-than-contracted ethane supply from Pemex. The company recorded a loss of R$654 million in the first quarter and net revenue fell by 32%.

We request clarification on the highlighted items by May 18, 2026, with confirmation or denial, as well as any other information deemed relevant.”

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

In this context, as also disclosed by the Company in the Market Notice published on September 8, 2025, and in the Material Fact disclosed on January 12, 2026, Braskem Idesa has retained specialized financial and legal advisors to support the evaluation of such alternatives, and has engaged in discussions with representatives of an ad hoc group of Braskem Idesa’s financial creditors, seeking a reorganization of its capital structure.

Additionally, as also disclosed by the Company in the Market Notices published on November 19, 2025, and February 20, 2026, Braskem Idesa reported the non-payment of scheduled interest due on November 18, 2025 and February 20, 2026, related respectively to its senior secured notes maturing in 2029 and 2032.

Furthermore, in the Company’s Financial Information for the period ended March 31, 2026, disclosed on May 13, 2026 (“Quarterly Information”), Braskem reported that the evaluations and discussions with the ad hoc group of Braskem Idesa’s financial creditors were ongoing, aiming at reorganizing its capital structure, including the assessment of potential protective measures (e.g., Chapter 11 under U.S. law), with potential impacts on the Company and on the shareholding control of Braskem Idesa. With respect to the financing obtained by TQPM for the construction of the ethane import terminal in Mexico (“TQPM”), Braskem reported that it provided a guarantee through an Equity Support Agreement which, as of the end of March 2026, covered 50% of the outstanding balance of TQPM’s financing, with the remaining 50% guaranteed by the other shareholder of TQPM until the Collateral Perfection Date of such financing. After reaching this milestone, Braskem must provide support to cover monthly payments under the agreement entered into between Braskem Idesa and TQPM up to the outstanding balance of TQPM’s financing.

Finally, as disclosed in the Quarterly Information, discussions with the ad hoc group of Braskem Idesa’s financial creditors remain ongoing, and the adoption of potential protective measures by Braskem Idesa may have impacts on the Company, including with respect to the shareholding control of Braskem Idesa and the aforementioned equity support guarantee. Nevertheless, we clarify that, as of this date, there is no decision regarding which alternative (or set of alternatives) will be implemented.

We remain at your disposal for any further clarification that may be required.
