FAQ

What is the main purpose of Braskem (BAK) creating internal rules for its Compliance and Audit Committee?

The new rules formally define how Braskem’s Compliance and Audit Committee supports the Board on compliance, audit, risk and governance matters. They clarify duties, powers, structure and procedures so the committee can operate with autonomy, documented authority and alignment with Brazilian, U.S. and NYSE regulations.

How is Braskem (BAK)’s Compliance and Audit Committee structured under the new regulations?

The committee has five members appointed by the Board for two-year terms, with a maximum of ten years’ service.

What is the role of the Compliance and Conformity Officer at Braskem (BAK)?

Braskem must maintain a dedicated compliance area led by a non-statutory Compliance and Conformity Officer, reporting to the Board and the committee.

Preferably, all members of the CAE should be present at all meetings, whether in person or by means of telephone conference, videoconference or any other means of communication. The minimum quorum for the installation of meetings must be more than half of the members. The member of the CAE who is unable to attend the meeting must inform the CAE Coordinator in advance and indicate, if applicable, which member will represent him.

The decisions or recommendations of the CAE are made by the majority of its members and must be recorded in minutes prepared by the S-CA and, after being validated by the members of the CAE, made available on Braskem's Governance Portal. The minutes must be filed by the Corporate Governance area at the Company's office or in external custody.

The members of the CAE may record in the minutes their observations, recommendations or divergent votes in relation to the matters under consideration. The registration of the divergence is an individual right and must be included in full in the corresponding minutes.

The Compliance and Conformity Officer shall have the right to request the CAE Coordinator to include specific matters in the agenda of the Committee's meetings, by means of a reasoned written communication, at least five (5) business days prior to the date of the meeting. The CAE Coordinator shall include the matter in the agenda of the next ordinary meeting or, in cases of justified urgency, call an extraordinary meeting to consider the matter.

The CAE shall, prior to the assessment of matters related to compliance policies, structure of the compliance area, budget of the compliance area and performance evaluation of the compliance program, request an advisory opinion from the Compliance and Conformity Officer. The opinion must be submitted within 10 (ten) business days from the request and will be non-binding, and the CAE must justify any deliberation diverging from the opinion.

The Compliance and Conformity Officer will be a permanent guest at the CAE's meetings, and may participate in all sessions, except those in which there is a conflict of interest or when the CAE decides, by majority, to hold an executive session without the presence of members of the management. The Compliance and Conformity Officer shall not have the right to vote in the deliberations of the CAE.

The S-CA shall make available, on the Corporate Governance Portal, to the Compliance and Conformity Officer, within five (5) business days after validation by the members of the CAE, a full copy of the minutes of the Committee's meetings, as well as the approved reports, opinions and recommendations. The Compliance and Conformity Officer must maintain confidentiality regarding the information received, observing the same confidentiality duties applicable to CAE members.

4.7.1. Quarterly Meetings with the Chief Compliance and Conformity Officer

The CAE will hold at least four (4) ordinary meetings per year with the Compliance and Conformity Officer, preferably quarterly, to report, monitor and discuss: (i) the status of implementation of the Company's compliance program; (ii) the main compliance risks identified and respective mitigation plans; (iii) the progress of relevant internal investigations; (iv) the effectiveness of internal controls related to compliance; and (v) the planning of compliance activities for the subsequent period. Such meetings may be held in conjunction with the regular meetings of the CAE or in specific sessions, at the discretion of the CAE Coordinator, subject to the availability of the Compliance and Conformity Officer.

4.8. Conflict of Interest

If any of the members of the Committee is in a situation of conflict of interest with a certain matter to be considered, they must promptly manifest themselves to the Coordinator or to the S-CA, being prevented from deliberating or otherwise intervening in the subject matter of the conflict. The impediment of the participation of the member of the Committee will be recorded in the minutes of the meeting. If you fail to express your conflict of interest, any member of the Committee who is aware of the situation must do so. Exceptionally, to protect its interests, the Company, by decision of the Legal Area, may restrict the access by conflicting members to information and materials related to the subject of conflict of interest, as well as to the part of the meeting that deals with the subject.

The document management related to the work of the CAE will observe formal information security standards, including: (i) secrecy and confidentiality; (ii) secure storage; (iii) restricted access control; and (iv) institutionalized flow of information through the S-CA.

The minutes of the CAE's meetings may be made available in full or in the form of an extract, upon resolution of the Committee, subject to confidentiality restrictions arising from sensitive information, ongoing investigations or protection of the Company's legitimate interest.

Communications between CAE members and their advisors, internal or external, must be carried out under secrecy and confidentiality, and their disclosure to unauthorized third parties is prohibited, except in the cases provided for by law or at the request of competent authorities.

The S-CA is responsible for ensuring that all documents, agendas, presentations, opinions, reports and support materials of the CAE are organized, recorded, maintained and filed in accordance with the Company's internal standards and norms of Corporate Governance, information security and document management.

The confidentiality of the information passed by each of the members of the Committee is and will remain confidential even if the member ceases to be a member of the Committee and will extend for a period of eight (8) years after his or her departure.

4.13. General Provisions

In the event of any conflict between these Rules and the Company's Bylaws, the latter shall prevail and these Rules shall be amended, to the extent necessary.
