MATERIAL FACT

São Paulo, May 9, 2023 - Braskem S.A. (“Braskem” or “Company”) (Ticker B3: BRKM3, BRKM5, and BRKM6; NYSE: BAK; LATIBEX: XBRK), in compliance with Official Letter No. 140/2023/CVM/SEP/GEA-1, sent by the Brazilian Securities Commission (“CVM”), which determined that the Company republish the Material Fact disclosed on May 8, 2023 “with complete, clear and objective information on the proposal received”, informs the market in general that, after sending the said letter to its controlling shareholder Novonor, it received, at 11:11 PM, the following additional information:

“Dear Sirs:

We refer to your e-mail dated 05.08.2023, whereby you forwarded to us CVM Official Letter No. 140/2023/CVM/SEP/GEA-1, dated 05.08.2023, concerning the response of Braskem S.A. ("Company") to CVM Official Letter No. 136/2023/CVM/SEP/GEA-1, in connection with the Material Facts disclosed by the Company on 05.05.2023 and 05.08.2023 ("Official Letter"), and request clarifications on the matter.

In said Official Letter, the CVM requests that the Company, in view of news published in the press with details of a potential transaction involving the Company, republish the Material Fact of 05.08.2023, which must contain "complete, clear and objective information about the proposal received, which must confirm or deny all the points mentioned in the news, in addition to other information considered important on the subject.

In compliance with the request, and reiterating our previous messages regarding this matter, Novonor S.A. ("Novonor") confirms that it has received from Apollo Management X, L.P. (together with Apollo Global Management, Inc. and its affiliates, as representatives of certain funds under its management) ("Apollo") and ADNOC International Limited - Sole Proprietorship L. L.C. ("ADNOC" and, together with Apollo, the "Prospective Investors") a non-binding offer for the indirect acquisition of the interest held by Novonor in the Company ("Offer"), the shares of which are fiduciarily disposed of to the creditor banks ("Creditor Banks"). The Offer is also intended for the Creditor Banks.

Although the Offer is subject to a confidentiality agreement (the disclosure of which, in our case, may lead to the loss of validity of its terms), Novonor is expressly permitted to share the terms of the Offer with Braskem in order to comply with the applicable specific disclosure rules. Accordingly, we are forwarding to you a complete copy of the Offer.

Novonor reiterates that the Offer is under its evaluation and emphasizes that no decision, even if preliminary, has been made with respect to it.

Sincerely”

With respect to price, the non-binding proposal received by Novonor establishes R$47.0 per share with the usual adjustments for this type of transaction, which may represent 4% between signing and closing of the transaction. The price per share is divided into:

(i) R$20.0 paid at sight, in cash;

(ii) R$20.0 paid with perpetual debentures issued by the acquiring vehicles, at a rate of 4% per year; and

(iii) approximately R$7.0 with deferred payment in the form of a warrant.

The non-binding proposal depends on evaluation and negotiation with Petrobras and its effectiveness is subject to compliance with certain conditions that are usual for this type of transaction, including but not limited to the realization of a due diligence process and approval by the competent bodies of the companies involved.

Finally, Braskem reinforces that it does not conduct any negotiations of its Shareholders Novonor and Petrobras on the sale of its shareholdings.

The Company informs that it will continue to support the Shareholders and keep the market informed about relevant developments, in compliance with the applicable laws.
