NOTICE TO THE MARKET

São Paulo, March 7, 2023 - Braskem S.A. (“Braskem” or “Company”) (Ticker B3: BRKM3, BRKM5 and BRKM6; NYSE: BAK; LATIBEX: XBRK), within the scope of the geological event in Alagoas, informs its shareholders and the market that it has become aware of the following actions filed against the Company and other defendants as detailed below:

In the ACP, the DPE-AL pleads for measures related to the Flexais region, including (i) the registration of residents of this region so that they can opt for relocation through the Company's Relocation and Financial Compensation Program (“PCF”); and (ii) the claim for compensation in the amount of R$1.7 billion for moral and material damages allegedly owed to residents of this region, with a subsidiary claim for judicial blocking of said amount.

In this regard, the Company reiterates that, on October 26, 2022, the judgment of the 3^rd Federal Court of Maceió approved the Term of Agreement for the Implementation of Socioeconomic Measures for the Requalification of the Flexal Area (“Flexais Agreement”) entered into by the Company with the Federal Public Prosecutor's Office, State Public Prosecutor's Office, Federal Public Defender's Office and Municipality of Maceió for the adoption of requalification actions in said region; and payment of compensation to the Municipality of Maceió and indemnities to residents of this locality. The estimated disbursement amounts for the execution of the obligations defined in the Flexais Agreement are already provisioned by the Company.

In the State of Alagoas Action, the State of Alagoas claims compensation for alleged damages caused to that State, including loss of tax revenue and loss of properties located in the risk area. Additionally, on an injunction basis, the State of Alagoas requests a judicial blocking in the amount of R$1 billion as a guarantee for compensation for property damage allegedly suffered by the State Public Administration.

In this regard, the Company informs that it was not summoned in the records of said action, but will evaluate and take the relevant measures within the applicable legal deadlines.

Braskem will keep the market informed of relevant developments, in compliance with applicable laws.

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.
