Re: Official Letter 128/2023/CVM/SEP/GEA-1

Dear Sirs,

In reference to Official Letter 128/2023/CVM/SEP/GEA-1 ("Official Letter"), dated April 26, 2023, in which you requested clarifications from Braskem S.A. ("Braskem" or "Company”), as transcribed and translated below:

“Dear Executive Officer,

We refer to the news published by the CMA Agency on April 25, 2023, news section, under the title: "Justice of Alagoas suspends blocking of Braskem accounts and action leads to increases in the Ibovespa", which contains the following statements:

Braskem informed that the Court of Justice suspended, on April 23, the effectiveness of the decision to block R$ 1.1 billion from the company's bank accounts referring to lawsuits filed against the company regarding geological events that occurred in the state of Alagoas, as previously given by the Court of First Instance. The information is contained in the 20F form filed this Monday (2/24) by the company to the Securities and Exchange Commission (SEC) and the Securities and Exchange Commission (CVM), for the year 2022.

In view of the foregoing, we determine that you clarify whether the news is true, and, if so, explain the reasons why you understood that it was not a relevant fact, as well as comment on other information considered important on the subject, including the performance of the securities issued on 04.25.2023 and the apparent non-compliance with the guidance contained in item 5.5 of LETTER CIRCULAR/ANUAL-2023-CVM/SEP.”

In this regard, the Company informs that on April 20, 2023, it released a notice to the market about the precautionary block in the approximate amount of R$1.1 billion in the Company's bank accounts determined by the Judge of the 16^th Civil Court of the Capital of Alagoas. After that date, the Company offered guarantee insurance for the same amount to replace the precautionary blocking order previously made, which was accepted by the Court of Justice of Alagoas (appealable decision by the plaintiff). In this sense, the Company understands that there was no material change from what had previously been communicated to the market.

Additionally, Braskem clarifies that there was no relevant fact or act not disclosed by the Company that justifies the performance of its securities on 04.25.23.

Finally, with regard to item 5.5 of the LETTER CIRCULAR/ANUAL-2023-CVM/SEP, the Company will release a translated version of its Form 20-F into Portuguese as soon as possible, as recommended in the aforementioned item of the Letter Circular.

Being what we had for the moment, we subscribe, making ourselves available for further clarifications if necessary.

São Paulo, April 27, 2023.

Chief Financial and Investor Relations Officer

Braskem S.A.
