NOTICE TO THE MARKET

São Paulo, March 29, 2023 - Braskem S.A. (“Braskem” or “Company”) (Ticker B3: BRKM3, BRKM5 and BRKM6; NYSE: BAK; LATIBEX: XBRK) hereby informs its shareholders and the market that, in line with its strategy to expand the use of clean energy matrices in its industrial operations, celebrated a new purchase agreement of wind energy with Casa dos Ventos, which provides Braskem with a supply of up to 22 years.

Braskem estimates a reduction of 3.2 million tons of CO2 considering this agreement and the other contracts entered into by the company for the purchase of competitive renewable energy in Brazil, reaching more than 220 MW average in long-term wind and solar energy contracts, which represents approximately 40% of the energy purchased by Braskem in Brazil for its operations, thus contributing to the goal of reducing 15% of scope 1 and 2 emissions by 2030 and being carbon neutral by 2050.

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. Statements related to the possible outcome of legal and administrative proceedings, implementation of operational and financing strategies and investment plans, guidance on future operations, as well as factors or trends that affect the financial condition, liquidity or operating results of the Company are examples of forward-looking statements. Such statements reflect the current views of the Company's management and are subject to various risks and uncertainties, many of which are beyond the Company’s control. There is no guarantee that the events, trends or expected results will actually occur. 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. For a comprehensive description of the risks and other factors that could impact any forward-looking statements in this document, especially the factors discussed in the sections, see the reports filed with the Brazilian Securities and Exchange Commission (CVM). This Notice to the Market does not constitute any offer of securities for sale in Brazil.
