MANAGEMENT PROPOSAL

TO SPECIAL MEETING OF SHAREHOLDERS OF CLASS “B” PREFERRED SHARES OF BRASKEM S.A.

TO BE HELD ON FEBRUARY 25, 2022

Dear Shareholders,

The Management of Braskem S.A. (“Company” or “Braskem”) hereby presents this proposal (“Proposal”) regarding the matters on the agenda of the Special Meeting of Shareholders of Class "B" Preferred Shares of Braskem ("PNB Shareholders”), to be held on February 25, 2022, at 10:00 a.m., with participation exclusively digitally, in accordance with article 4, paragraph 2, item I and article 21-C, paragraphs 2 and 3 of Instruction 481, issued by the Securities and Exchange Commission of Brazil (“CVM”) on December 17, 2009 (“CVM IN 481”), via the digital platform WebEx (“Digital Platform” and “Special Meeting,” respectively).

In connection with the studies that have been conducted for the potential migration of the Company to the Novo Mercado segment of B3 S.A.- Brasil, Bolsa, Balcão (“B3”), as announced in the Material Fact notice dated December 16, 2021, and aiming to simplify the capital structure of the Company, equalize rights between holders of Class "B" Preferred Shares and the holders of Class "A" Preferred Shares and prepare for a future unification of the classes and types of preferred shares into common shares, if such migration comes to be approved, Management proposes to PNB Shareholders the approval of the conversion of all Class "B" Preferred Shares issued by the Company into Class "A" Preferred Shares, in accordance with article 136, paragraph 1 of Federal Law 6,404/76, at the ratio of two (2) class "B" preferred shares to one (1) class "A" preferred share, in line with the ratio established in article 6, paragraph 3 of the Bylaws of the Company for the voluntary conversion of such shares.

The Company clarifies, however, that, in line with said Material Fact notice, the migration to the Novo Mercado and the corporate changes necessary for such still depend on the conclusion of the ongoing studies, the negotiation of a new Shareholders Agreement to adjust the rights and obligations of shareholders to the new corporate structure of the Company and, further, the applicable approvals by the Board of Directors and, if applicable, by the General and Special Shareholders Meetings of the Company.

The Class “B" Preferred Shares originated from subscriptions made using funds from tax incentives, pursuant to tax law and as established in the Bylaws of the Company, and correspond to 0.06% of the share capital of the Company, with low trading liquidity.

As a result of the proposed conversion, if approved, the current four hundred seventy-eight thousand, seven hundred and ninety (478,790) Class "B" Preferred Shares issued by the Company will be converted into two hundred thirty-nine thousand, three hundred and ninety-five (239,395) Class "A" Preferred Shares which, combined with the existing three hundred forty-five million, sixty thousand, three hundred and ninety-two (345,060,392) Class "A" Preferred Shares, will amount to three hundred forty-five million, five hundred thirty-nine thousand, one hundred and eighty-two (345,539,182) Class "A" Preferred Shares.

The Company clarifies that the conversion, if approved by the Special Meeting, will be conditioned upon approval in the Shareholders Meeting of the Company, to be convened opportunely, by a vote of shareholders representing at minimum half of the total votes conferred by the shares with voting rights issued by the Company, in accordance with art. 136, head paragraph and subitem II of Federal Law 6.404/76.

The ownership and political rights attributed to the new Class "A" Preferred Shares will be identical to the ownership and political rights attributed to the existing shares. The information on changes to the preferences, advantages or conditions for redemption or amortization of the Class "B" Preferred Shares, under article 17 of CVM IN 481, is available in Appendix I to this Proposal.

Although Class "A" Preferred Shares enjoy rights and advantages superior to those of the Class "B" Preferred Shares, considering the conversion ratio proposed, the PNB Shareholders will have the right to withdrawal, in accordance with article 137, item I of Federal Law 6,404/76, if and when said conversion is effectively approved by a General Meeting. Information on the right of withdrawal of the Class "B" Preferred Shares, under article 20 of CVM IN 481, is available in Appendix II to this Proposal.

As permitted by Brazilian Corporation Law and by CVM IN 481, the Special Meeting will be held exclusively digital, which means that Shareholders may participate only via the Digital Platform, personally or by a proxy duly empowered in accordance with art. 21-C, §2 and 3§ of CVM IN 481, in which case Shareholders may: (i) simply participate in the Meeting; or (ii) participate and vote in the Meeting.

Voting via absentee ballot will not be adopted for the purposes of the Meeting, in accordance with CVM IN 481.

2.               In the event of changes to the preferences, advantages or conditions for redeeming or amortizing preferred shares:

The proposal provides for the conversion of all Class "B" Preferred Shares issued by the Company into Class "A" Preferred Shares, at the ratio of two (2) Class "B" Preferred Shares to one (1) Class "A" Preferred Share, in line with the ratio established in art. 6, §3 of the Bylaws of the Company for the voluntary conversion of such shares

As a result of the conversion, if approved, the current four hundred seventy-eight thousand, seven hundred and ninety (478,790) Class "B" Preferred Shares issued by the Company will be converted into two hundred thirty-nine thousand, three hundred and ninety-five (239,395) Class "A" Preferred Shares which, combined with the existing three hundred forty-five million, sixty thousand, three hundred and ninety-two (345,060,392) Class "A" Preferred Shares, will amount to three hundred forty-five million, five hundred thirty-nine thousand, one hundred and eighty-two (345,539,182) Class "A" Preferred Shares.

The Company clarifies that the conversion, if approved by the Special Meeting, will be conditioned upon approval in the Shareholders Meeting of the Company, to be convened opportunely, by a vote of shareholders representing at minimum half of the total votes conferred by the shares with voting rights issued by the Company, in accordance with art. 136, head paragraph and subitem II of Federal Law 6.404/76.

The ownership and political rights attributed to the new Class "A" Preferred Shares will be identical to the ownership and political rights attributed to the existing shares.

The purpose of the conversion is to simplify the ownership structure of the Company, which currently is divided into two classes of Preferred Shares, and to equalize the rights attributed between Class "B" Preferred Shareholders and Class “A” Preferred Shareholders, including those related to the payment of dividends. Furthermore, the conversion is the result of ongoing studies for a possible migration of the Company to the Novo Mercado listing segment of B3, as disclosed in the Material Fact notice dated December 16, 2021. If approved, the conversion will enable the Company to consolidate its Preferred Shares into a single class, ensuring higher liquidity for the holders of Class “B” Preferred Shares and resulting in a less complex ownership structure. The Class “B” Preferred Shares represent 0.06% of the share capital of the Company.

The Company clarifies, however, that, in line with said Material Fact notice, the migration to the Novo Mercado and the corporate changes necessary for such still depend on the conclusion of the ongoing studies, the negotiation of a new Shareholders Agreement to adjust the rights and obligations of shareholders to the new corporate structure of the Company and, further, the applicable approvals by the Board of Directors and, if applicable, by the General and Special Shareholders Meetings of the Company.

Given that the Class “A” Preferred Shares enjoy preferences and advantages over the Class “B” Preferred Shares, the conversion will have a positive impact on the rights of PNB Shareholders, because, since after the conversion:

The Class “B” Preferred Shares currently correspond to zero point one four percent (0.14%) of the total preferred shares issued by the Company and zero point zero six (0.06%) of the total shares issued.

The conversion will result in increases in the number of Class “A” Preferred Shares issued and in the interest that shareholders of Class “A” Preferred Shares will hold jointly in the total share capital issued by the Company. Consequently, the conversion will affect the distribution, between the holders of common shares and Class "A" Preferred Shares, of the profits remaining after the distribution assured to the Class “A” Preferred Shares and to the common shares of the dividend corresponding to six percent (6%) of the unit value, in accordance with art. 9, (c) of the Bylaws of the Company. However, given that the Class “B” Preferred Shares represent a minimal portion of the share capital, the impact on dividend distributions to the Class “A” Preferred Shares and the common shares will be marginal.

The Company reinforces that the change in proportion between the numbers of the various classes of preferred shares is expressly authorized by art. 4, §4 of the Bylaws of the Company.

MANAGEMENT PROPOSAL

TO SPECIAL MEETING OF SHAREHOLDERS OF CLASS “B" PREFERRED SHARES

TO BE HELD ON FEBRUARY 25, 2022

Appendix 20 to CVM IN 481

Withdrawal Rights

Withdrawal rights will be conferred to the holders of Class "B" Preferred Shares (“PNB Shareholders”), in accordance with item I or article 137 of Federal Law 6,404/76, in view of the proposal for the conversion of two (2) Class "B" Preferred Shares into one (1) Class “A” Preferred Share. Withdrawal rights will be assured if and when this conversion is approved by a General Meeting of Shareholders.

In accordance with article 137 of Brazilian Corporation Law, the right to withdraw from the Company will be conferred only to PNB shareholders who (i) are dissidents from the resolution of the Special Meeting; (ii) have abstained from voting in the resolution of the Special Meeting; or (iii) did not participate in the Special Meeting. Said right only will be conferred to Class “B” Preferred Shares that are held by these shareholders uninterruptedly from the close of trading on February 2, 2022 (disclosure date of the Material Fact notice on the approval of the conversion by the Board of Directors) to the date of the effective exercise of the withdrawal right.

The Material Fact notice on the conversion and the call notice for the Special Meeting were disclosed on February 2, 2022 in the Empresas.NET System, on the website of the B3 and on the Investor Relations website of the Company.

PNB Shareholders who want to withdraw from the Company will have at least thirty (30) days as from the disclosure date of the minutes of the General Meeting that approved the conversion to exercise their right.

If this right is not exercised within said period, it will be lost, in accordance with paragraph 4 of article 137 of Brazilian Corporation Law.

The cutoff date for determine those shareholders who are entitled to the withdrawal rights and the other information required for exercising the withdrawal rights will be disclosed on a timely basis via a Notice to Shareholders upon approval of the conversion by the General Meeting.

The reimbursement amount based on the book value stated in the financial statements of the Company for the fiscal year ended December 31, 2020 would be zero, since the net equity value of the Company based on these financial statements is negative.

However, since the withdrawal rights are guaranteed only after approval of the conversion by the General Meeting, when the financial statements of the Company for the fiscal year ended December 31, 2021 will already have been at least disclosed, the reimbursement amount will be calculated and informed on a timely basis based on said financial statements. For illustrative purposes only, if the reimbursement amount was calculated based on the book value at September 30, 2021 stated in the most recent Quarterly Financial Information (ITR) of the Company, said reimbursement would correspond to R$16.01 per share.

The reimbursement will be calculated by multiplying the reimbursement value per share for the number of Class "B" Preferred Shares in the Company held by the shareholder, observing the aforementioned items.

Dissenting PNB Shareholders may request, jointly with the reimbursement, the preparation of a special balance sheet, in accordance with paragraph 2 of article 45 of Brazilian Corporation Law, provided the resolution of the General Meeting occurs more than sixty (60) days after the date of the last balance sheet approved.

Not applicable.

Not applicable.

Not applicable.

The book value of each share based on the most last balance sheet approved by the Annual and Extraordinary Shareholders Meeting held on April 13, 2021 is negative R$2.76.
