São Paulo, January 3, 2023 - BRASKEM S.A. (“Braskem” or “Company”) (B3: BRKM3, BRKM5 e BRKM6; NYSE: BAK; LATIBEX: XBRK) hereby announces to its shareholders and the market that the Board of Directors approved the hiring of KPMG Auditores Independentes Ltda.

KPMG audited the Company's financial statements from 2015 to 2019 and, due to the mandatory rotation of independent auditors provided for in article 31 of CVM Resolution No. 23/21, it was replaced by Grant Thornton from 2020 to 2022.

The Company also informs that KPMG will continue to provide auditing services to comply with US legislation and regulations.

DISCLAIMER ON FORWARD-LOOKING STATEMENTS

This Notice to the Market may contain forward-looking statements. These statements are not historical facts, but rather are based on the current view and estimates of the Company's management regarding future economic and other circumstances, industry conditions, financial performance and results, the geological event in Alagoas and related legal procedures and from COVID-19 on the Company's business, financial condition and operating results. The words “project,” “believe,” “estimate,” “expect,” “plan” and other similar expressions, when referring to the Company, are used to identify forward-looking statements.

The statements are based on various assumptions and factors, including general economic and market conditions, industry conditions and operating factors. Any change in these assumptions or factors, including the projected impact from the joint venture and its development of technologies, from the geological event in Alagoas and related legal procedures and the unprecedented impact from COVID-19 on businesses, employees, service providers, shareholders, investors and other stakeholders of the Company could cause effective results to differ significantly from current expectations.
