MATERIAL FACT

Braskem S.A. ("Braskem" or "Company"), pursuant to CVM Resolution 44/21 and complementing the Notice to the Market dated as of September 28, 2021, hereby announces to its shareholders and the market that its indirect subsidiary Braskem Idesa ("BI") has secured the applicable corporate approvals, including final approval by its shareholders and creditors regarding (i) the Amendment to the ethane supply agreement signed with PEMEX Transformación Industrial and with PEMEX Exploración y Producción ("PEMEX") and (ii) the Agreement with measures to support the construction of an ethane import terminal signed with Petróleos Mexicanos, PEMEX Logística and other government entities.

Furthermore, BI concluded its debt refinancing plan replacing remaining balance of US$1.35 billion from Project Finance with new debt instruments under a corporate format and with a long maturity profile, which effectively lengthened its average debt maturity term to 9 years. With the settlement of the Project Finance debt, the guarantees pledged by Braskem to BI, in the total amount of US$358 million, will be extinguished.

The new capital structure of BI includes the issue of debt securities with commitment and interest rates linked to targets for reducing carbon emissions, in line with the Company's long-term sustainable development strategy.

In this way, Braskem fulfills its objective established for 2021 of negotiating a definitive amendment with PEMEX and expanding the ethane import operations and, through BI, reinforces its commitment to Mexico, to the local petrochemical industry and to the continuous search for increasing the availability of feedstock for the plastic transformation industry.
