In the event of any conflict or questioning between the concept or scope of Related Parties defined in this Policy and that of the PCP 05(R1), as amended, the rules of CPC 05(R1) or any other that may replace it will prevail.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;5.2 IDENTIFICATION OF BRASKEM'S RELATED PARTIES

The List of Related Parties shall be made available to the Company's areas for prior consultation before entering into contracts or transactions of any nature by any Company Member, who must identify and inform Braskem's Corporate Governance Area whenever such contracts or transactions qualify as a Related Party Transaction.

The List of Related Parties is prepared and periodically updated based on the form completed by the controlling shareholder(s), shareholder(s) exercising Significant Influence over the Company, and Key Persons of the controlling shareholder(s), Braskem, and its Controlled Companies, through which Braskem's Corporate Governance Area identifies the Related Parties.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;5.3 NEGOTIATION OF RELATED PARTY TRANSACTIONS

Related Party Transactions may involve the transfer of resources, provision of services, purchase or sale of goods, or assumption of obligations, whether for consideration or free of charge. Such transactions must be negotiated independently and transparently, under commutative conditions or with appropriate compensatory payment. Whenever possible, potential alternatives to such transactions should be considered to ensure the Company's best interest.

![](bak202508146k_003.jpg)

Transactions must also be supported by reasonable economic and business grounds, representing the best available alternative for Braskem and its Controlled Companies at the time of execution. Related Party Transactions must be formalized in writing, specifying their key characteristics, terms, and other relevant information.

The Company shall establish the appropriate processes and requirements to ensure that corporate restructuring transactions (such as mergers, consolidations, share incorporations, transformations, and spin-offs), involving the Company and/or its Controlled Companies on one side, and Related Parties on the other, are carried out under commutative conditions.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;5.4 ANALYSIS AND GOVERNANCE FOR THE APPROVAL OF RELATED
PARTY TRANSACTIONS

The execution of any Related Party Transaction must be preceded by review and approval, as applicable, by the General Shareholders' Meeting, the Board of Directors, or the Contracting Area, in accordance with the Company's Delegation of Authority Guideline and the provisions of this Policy.

Any Related Party Transaction subject to approval by the Board of Directors or reporting to the Corporate Governance Area, pursuant to this Policy, must be accompanied by the corresponding Related Party Form prepared by the Contracting Area and reviewed by the respective legal support team. This form must specify the key terms and conditions of the transaction, including a description of available market alternatives, the selection process, and the rationale for choosing the Related Party, or the justification for the absence of a selection process, where applicable.

The bodies or individuals responsible for reviewing or approving Related Party Transactions under this Policy may request opinions, reports, and/or valuation assessments from third parties (such as investment banks, law firms, accounting firms, among others), provided such third parties have no involvement or interest in the Related Party Transaction in question, in order to clarify any doubts and/or support the decision-making process.

Except as expressly permitted by this Policy or by the Board of Directors, within its duties and responsibilities, no Related Party Transaction may be executed prior to the completion of its approval as set forth herein, subject to the exemptions provided in this Policy.

![](bak202508146k_003.jpg)

Additionally, without prejudice to the treatment required under applicable laws and regulations, including disclosures in the financial statements, the following Related Party Transactions entered into by the Company and/or any of its Controlled Companies shall not be subject to the approvals set forth in this Policy and are exempt from reporting to the Corporate Governance Area, as applicable, provided they are carried out under commutative conditions or with appropriate compensatory payment, and in accordance with the Delegation of Authority Guideline and other applicable Company guidance documents:

&nbsp;&nbsp;&nbsp;&nbsp;· Confidentiality agreements for
the receipt or disclosure of information, provided they do not contain other obligations, such as exclusivity or the execution of additional
contracts;

&nbsp;&nbsp;&nbsp;&nbsp;· Letters of intent, memoranda
of understanding, or other non-binding preliminary instruments, provided they do not impose exclusivity obligations or otherwise restrict
the activities of the Company and/or any of its Controlled Companies;

&nbsp;&nbsp;&nbsp;&nbsp;· Sending and receiving product
samples up to an individual limit of R$50,000.00 (fifty thousand reais) per production batch, in accordance with the Company's guidance
documentation applicable to this type of transaction;

&nbsp;&nbsp;&nbsp;&nbsp;· Transactions resulting from
compliance with administrative, judicial, or arbitral decisions; and

&nbsp;&nbsp;&nbsp;&nbsp;· Transactions entered into between
Braskem and entities directly or indirectly controlled by Braskem on an individual basis (excluding joint control), as well as transactions
entered into between entities directly or indirectly controlled by Braskem on an individual basis (excluding joint control), shall be
exempted, except in cases where there is equity participation in the controlled entity by Braskem's controlling shareholder or by
Key Person(s) associated with the controlling shareholder.

The Board of Directors may, upon justified grounds, determine that other Related Party Transactions shall not be subject to the approvals set forth in this Policy, provided that such transactions are carried out under commutative conditions or with appropriate compensatory payment, and that, in their approval process, alternative options to the execution of such transactions are considered whenever applicable.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;5.5 PROHIBITIONS

Related Party Transactions shall be prohibited when:

![](bak202508146k_003.jpg)

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· they are not in compliance with this Policy, Braskem's Bylaws, or applicable legislation; or

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· they constitute loans granted in favor of (i) the Company's controlling shareholder or (ii) Key
Persons of (a) the Company and/or (b) its controlling shareholder.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;5.6 DISCLOSURE OF RELATED PARTY TRANSACTIONS

For purposes of disclosing the Financial Statements and the information contained in the Reference Form filed with the Brazilian Securities and Exchange Commission (CVM), as well as in the disclosure of Notices regarding Related Party Transactions pursuant to CVM Resolution No. 80/22, the Company shall apply the concepts and rules governing Related Parties as set forth in applicable laws and regulations.

In any disclosures required by applicable law or regulation, Braskem shall provide sufficient information to identify the Related Parties and the subject matter of the Transaction, along with any other required information, in order to enable the Company's shareholders to monitor and assess management's activities related to such transactions.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;5.7 SITUATIONS INVOLVING POTENTIAL CONFLICTS OF INTEREST

A potential conflict of interest arises when a shareholder, Member, or Key Person of the Company and/or its Controlled Entities is involved in a decision-making process in which their ability to exercise objective and impartial judgment may be compromised due to: (i) having the power to influence the outcome of the decision, and simultaneously (ii) the decision potentially resulting in a gain, benefit, or advantage for themselves, a Close Relative, or a Third Party with whom the shareholder, Member, or Key Person of the Company and/or its Controlled Entities is involved ("**Conflict of Interest**").

Given the potential for Conflict of Interest in such situations, the Company and its Controlled Entities shall seek to ensure that all decisions that may result in private gains, benefits, or advantages not shared with the Company and/or its Controlled Entities, for any shareholder, Member, Key Person, Close Relative, or related entities or individuals, are made with full transparency and in alignment with the best interests of the Company and/or its Controlled Entities, as applicable.

Within the scope of the Company's general shareholders' meetings, any Conflict of Interest involving a shareholder shall be addressed in accordance with Law No. 6,404/76, taking into account CVM guidance on the matter. If there is strong indication of a potential Conflict of Interest that may lead to disqualification or invalidation of a vote, the chairperson of the shareholders' meeting shall inquire the shareholder and remind them of their responsibilities, leaving it to the shareholder to assess the existence of a conflict and determine whether they are disqualified from participating in the resolution.

![](bak202508146k_003.jpg)

Furthermore, without prejudice to the rules set forth in the Company's guiding documents addressing Conflicts of Interest, Members and Key Persons of the Company and/or its Controlled Entities who identify the possibility of participating in a decision-making process involving a potential conflict must disclose such potential conflict to their Leader or to the other members of the competent body, as applicable. Additionally, such Members and Key Persons must refrain from participating in discussions on the matter and must abstain from negotiating, evaluating, expressing opinions, approving, voting, or otherwise influencing the handling or approval of the respective matter within the Company and/or its Controlled Entities, as applicable.

If requested by the members of the competent body, Key Persons in a Conflict of Interest situation may participate in discussions to provide further information regarding the matter and the parties involved, but must withdraw from the remainder of the discussion and the voting process.

If any Member or Key Person of the Company and/or its Controlled Entities stands to obtain a private gain, benefit, or advantage not shared with the Company and fails to disclose such situation, any other person aware of the matter must do so. The Member's Leader or the competent body shall then assess the situation collectively.

Any disclosure regarding the characterization of a potential Conflict of Interest and the resulting abstention from voting by the Key Person must be recorded in the minutes of the respective meeting.

Without prejudice to the foregoing, in situations where a Conflict of Interest involving any Member or Key Person of the Company and/or its Controlled Entities is identified and disclosed, the rules set forth in the Company's guiding documents on Conflicts of Interest and other applicable governance documents of Braskem must also be observed.

6. GENERAL PROVISIONS

Members are responsible for knowing and understanding all applicable Guiding Documentation. Likewise, Leaders are responsible for ensuring that their team members understand and comply with the Company's applicable Guiding Documentation.

Members who have questions regarding this Policy, including its scope, terms, or obligations, should contact their Leader or Braskem's Corporate Governance department.

![](bak202508146k_003.jpg)

If any Member or Third Party becomes aware of a potential violation of this Policy, they must immediately report the suspected violation through the Ethics Line Channel.

Violations of any of the Company's Guiding Documentation may result in serious consequences for Braskem and the Members involved. Therefore, failure to comply with this Policy or failure to report a violation may result in disciplinary action against the Member(s) involved.
