Report on the review of interim financial information (ITR)

(A free translation of the original report in Portuguese, as filed withthe Comissão de Valores Mobiliários - CVM, for the individual interim financial information prepared in accordance withthe Technical Pronouncement CPC 21 (R1) – Demonstração Intermediária, and for the consolidated interim financialinformation prepared in accordance with the Technical Pronouncement CPC 21 (R1) – Demonstração Intermediáriaand the international standard IAS 34 - Interim Financial Reporting, as issued by the International Accounting Standards Board - IASB)

To Shareholders, Members of the Board and Management

Braskem S.A.

Camaçari - Bahia

Introduction

We have reviewed the accompanying individual and consolidated interim financial information of Braskem S.A. (the “Company”) included in the Quarterly Information Form (ITR) for the quarter ended March 31, 2025, which comprises the statement of financial position as at March 31, 2025 and the related statements of profit or loss, comprehensive income (loss), changes in equity and of cash flows for the three-month period then ended, including the explanatory notes.

The Company’s management is responsible for the preparation of the individual interim financial information in accordance with CPC 21 (R1) - Demonstração Intermediária and the consolidated interim financial information in accordance with CPC 21 (R1) and international standard IAS 34 - Interim Financial Reporting, issued by the International Accounting Standards Board – (IASB), such as for the presentation of these information in accordance with the standards issued by the Comissão de Valores Mobiliários, applicable to the preparation of Quarterly Information Form (ITR). Our responsibility is to express a conclusion on this interim financial information based on our review.

Scope of review

We conducted our review in accordance with Brazilian and International Standards on Review of Interim Financial Information (NBC TR 2410 - Revisão de Informações Intermediárias Executadapelo Auditor da Entidade and ISRE 2410 - Review of Interim Financial Information Performed by the Independent Auditor of the Entity, respectively). A review of interim financial information consists of making inquiries, primarily of persons responsible for financial and accounting matters, and applying analytical and other review procedures. A review is substantially less in scope than an audit conducted in accordance with Standards on Auditing and consequently does not enable us to obtain assurance that we would become aware of all significant matters that might be identified in an audit. Accordingly, we do not express an audit opinion.

KPMG Auditores Independentes Ltda., uma sociedade simples brasileira, de responsabilidade limitada e firma-membro da organização global KPMG de firmas-membro independentes licenciadas da KPMG International Limited, uma empresa inglesa privada de responsabilidade limitada.	KPMG Auditores Independentes Ltda., a Brazilian limited liability company and a member firm of the KPMG global organization of independent member firms affiliated with KPMG International Limited, a private English company limited by guarantee.

Conclusion on the individual interim financial information

Based on our review, nothing has come to our attention that causes us to believe that the accompanying individual interim financial information included in the quarterly information referred to above was not prepared, in all material respects, in accordance with CPC 21 (R1) applicable to the preparation of Quarterly Information (ITR), and presented in accordance with the standards issued by the Comissão de Valores Mobiliários.

Conclusion on the consolidated interim financial information

Based on our review, nothing has come to our attention that causes us to believe that the accompanying consolidated interim financial information included in the quarterly information referred to above was not prepared, in all material respects, in accordance with CPC 21 (R1) and IAS 34, applicable to the preparation of Quarterly Information (ITR), and presented in accordance with the standards issued by the Comissão de Valores Mobiliários.

Other matters

Statements of value added

The interim information referred to above includes the individual and consolidated statements of added value (DVA) for the three-month period ended March 31, 2025, prepared under responsibility of Company’s management, and presented as supplementary information for IAS 34 purposes. These statements were submitted to review procedures performed together with the review of the quarterly information, to reach a conclusion on whether they are reconciled with the interim financial information and accounting records, as applicable, and if their form and content are in accordance with the criteria set forth in Technical Pronouncement CPC 09 – Demonstração do Valor Adicionado. Based on our review, nothing has come to our attention that causes us to believe that those statements of value added were not prepared, in all material respects, in accordance with the criteria set forth in that standard and consistently with the individual and consolidated interim financial information taken as a whole.

1Operations

Braskem S.A. (“Parent Company” or Braskem) is a public corporation headquartered in Camaçari, Bahia (“BA”), which, jointly with its subsidiaries (“Company”), is controlled by Novonor S.A. (“Novonor”), which directly and indirectly holds interests of 50.11% and 38.32% in its voting and total capital, respectively. The ultimate parent company of Braskem is Kieppe Patrimonial S.A.

The Braskem’s shares are traded on B3 S.A. Brasil, Bolsa, Balcão (“B3”), under the tickers BRKM3, BRKM5 and BRKM6, on the New York Stock Exchange (“NYSE”) under the ticker BAK and on the Madrid Stock Exchange (“LATIBEX”) under the ticker XBRK.

Braskem is engaged in the manufacture, sale, import and export of chemicals, petrochemicals and fuels, the production, supply and sale of utilities such as steam, water, compressed air and industrial gases, as well as the provision of industrial services and the production, supply and sale of electric energy and gas for its own use and use by other companies. Braskem also invests in other companies.

The Company has industrial plants in Brazil, the United States, Germany and Mexico. The units produce thermoplastic resins, such as polyethylene (“PE”), polypropylene (“PP”), polyvinyl chloride (“PVC”) and other basic petrochemicals.

As of March 31, 2025, the statement of financial position reflects a positive working capital (defined as total current assets minus total current liabilities) amounting to R$8,200 (2024: positive amount of R$8,765) in the consolidated and negative working capital amounting to R$1,508 (2024: negative amount of R$7,431) in the parent company. It also reflects negative equity of R$3,795 (2024: negative in R$4,278) in the consolidated and R$4,236 (2024: negative amount of R$4,782) in the parent company.

The Company used cash flow from operating activities amounting to R$2,332 (cash generation of R$ 965 as of March 31, 2024) in the consolidated and R$1,728 (cash generation of R$1,336 as of March 31, 2024) in the parent company as of March 31, 2025. Borrowings and debentures are predominantly due in the long term, with 95% denominated in US dollars, consistent with the Company's Financial Policy. The Company is comfortable with this US dollar exposure since a significant portion of the operational cash expected to be generated in the upcoming years, which will be allocated to settle these borrowings, is either directly or indirectly in US dollars.

New investments in capacity

In January 2025, the Company announced the execution of seven projects to expand its current production capacity in Bahia, Rio Grande do Sul and Alagoas, distributed among PE, PVC and other chemicals.

In February 2025, the Company approved the start of the project to increase the ethylene production capacity at its petrochemical plant in Rio de Janeiro. The project is part of the Company's transformation strategy by increasing the use of gas in its raw material matrix, seeking greater competitiveness of the Brazilian chemical industry.

3 New accounting standards applicable in the current year

The following changes of accounting standards became effective on January 1, 2025:

Lack of exchangeability (amendments to CPC 02/IAS 21).

Adoption of the amendment did not have any material impact on the disclosures or amounts presented in this quarterly information.

3.1	Review of Technical Pronouncement CPC 09 (R1) - Statement of Value Added (DVA)

In February 2024, the CVM approved resolution 199/2024, which introduced changes in the disclosure of the Statement of Value Added, applicable to fiscal years starting on or after January 1, 2024.

The resolution altered the definition of elements that are components of the revenue generated, without affecting the net value added produced. Based on the change, the Company adjusted, as from December 2024, the allocation of amounts related to the net realizable value of inventories, previously classified as inputs acquired from third parties, which are now classified as other income.

Thus, the DVA for the current year was released based on the new requirements, and the retrospective effects of the quarter ended March 2024 are restated below:

Cash equivalents in Brazil are represented by fixed-income instruments and time deposits, such as bank deposit certificates (“CDBs”), treasury bonds, financial bills, debentures, and shares of fixed income investment funds. These assets may be directly held by the Company or through its exclusive funds, FIM Jupiter and FIM Netuno. Average yield of cash equivalents is presented jointly with financial investments (see note 5).

In the period ended March 31, 2024, financial investments and cash equivalents (Note 4) in Brazilian Real had average yield of 102.03% of the Interbank Certificate of Deposit (“CDI”) rate p.a. (2024: 102.25%) and financial investments and cash equivalents in foreign currency (Note 4) had average yield of 4.85% p.a. (2024: 5.46% p.a.).

6Trade accounts receivable

The Company’s average receivables term is generally 30 days, therefore, the carrying value of the trade accounts receivable approximates their fair value.

The Company realizes part of its trade accounts receivable through the sale of trade notes to funds and financial institutions that acquire receivables. These operations are not entitled to recourse and substantial risks and benefits over the receivables are transferred and the trade accounts receivable are derecognized.

As of March 31, 2025, the amounts of trade accounts receivable transferred and derecognized maturing after March 31, 2025 were R$3.2 billion in the Parent Company and R$5.4 billion in the Consolidated (2024: R$2.9 billion in the Parent Company and R$5 billion in the Consolidated).

The bonds due in 10 years have an interest rate of 6.99% p.a., which may be increased by up to 0.37% p.a. if certain conditions are not met, which include the reduction of greenhouse gas (GHG) emissions by 15% in absolute terms by 2028, considering a baseline of 2017.

On April 23, 2025, Braskem Idesa entered into a new agreement with the lender in the amount of R$545 (US$95), maturing in April 2029, with quarterly interest payments (SOFR + 8.25% p.a.). This new financing was used for the early settlement of the existing financing, which originally matured in October 2026.

18 Financial instruments and risk management

18.1 Financial risk management

Overview

The Company approved, together with its Board of Directors, the financial policy that establishes concepts, criteria and power limits for decisions involving:

• Cash flow and liquidity risk management;

• Counterparty risk management; and

• Foreign exchange, index and interest rate, and commodity risk management.

The main objectives of the Company's financial policy are to ensure:

Proactive and continuous risk management through anticipation and, when necessary, protection against unfavorable scenarios, in order to protect the Company's results and assets;
The continuous alignment of the objectives of the teams involved in risk management with the Company's overall objectives;
The continuous preservation of the Company's financial health;
The protection of the Company's results and assets against the non-performance of financial obligations assumed by counterparties;
The efficiency and effectiveness in safeguarding against market risk exposures, currency exposures, and commodity exposures, through the use of financial instruments or by recognizing the presence of natural hedges and the correlations between the prices of different assets and markets, as well as in maintaining the balance between active and passive exposures;

In order to comply with the objectives of the financial policy, management conducts risk management as a continuous process, considering the exposed areas of the business, involving the identification, measurement, follow-up, monitoring, and, if necessary, the definition of limits and appropriate mitigation instruments under the circumstances. In line with risk management policies, every derivative operation must be linked to an effective exposure, without a speculative character.

18.2 Classification of financialinstruments

Transactions in financial instruments are recognized on the date the Company becomes a party to the contractual provisions of the instrument and end when they expire, are settled, received, or their risks and benefits are substantially transferred.

Financial assets are initially recognized at fair value, which corresponds to the transaction price, and are subsequently measured based on the management model of these assets by the management.

18.3 Fair value hierarchy

The Company classifies part of its financial instruments as carried at fair value and, depending on the inputs used in their measurement, such instruments can be classified into 3 levels of hierarchy. Level 1 indicates a value based on quoted prices for identical assets and liabilities, without any adjustments. Level 2 involves inputs from pricing models or the use of available prices for similar assets and liabilities. Level 3 involves pricing through a model based on data not available in the market.

The fair value of the financial instruments measured at the end of the year is shown below:

	Consolidated
	Level 1	Level 2	Total
Assets
Cash equivalents	-	6,305	6,305
Financial investments	-	1,756	1,756

Counterparty risk - Financial institutions

In defining counterparties for active financial operations, including derivatives, the criteria for classifying the counterparty's credit risk by a specialized agency should be observed. This involves using the local long-term rating for Brazilian institutions and the global rating for international institutions, as well as considering the concentration of exposure to the counterparty.

The Company accepts as counterparties financial institutions and issuers of securities that meet the minimum rating below:

Rating agency	Local minimum rating	Global minimum rating
Fitch Ratings	A+	BBB-
Standard & Poor's	A+	BBB-

Other agencies that have an equivalent reputation may be considered in the risk management process. In addition to the minimum rating, the Company also considers, as main criteria, the exposure by institution concentration, exposure relative to the counterparty's equity, and exposure by category of rating and Credit Default Swap ("CDS") of counterparties.

The exposure classified by credit risk rating of the cash and cash equivalents and financial investments is presented below:

18.5 Sensitivity analysis

Financial instruments, including derivatives, may be subject to changes in their fair value as a result of the variation in commodity prices, foreign exchange rates, interest rates, price indexes and other variables. The sensitivity of the derivative and non-derivative financial instruments to these variables are presented below:

Selection of risks

On March 31, 2025, the main risks that can affect the value of Company’s financial instruments are:

· IPCA inflation rate;

· Selic and CDI interest rates;

· SOFR interest rate;

· US$/R$ exchange rate;

· MXN/R$ exchange rate; and

· Euro/R$ exchange rate.

For the purposes of the risk sensitivity analysis, the Company presents the exposures to currencies as if they were independent, that is, without reflecting in the exposure to a foreign exchange rate the risks of the variation in other foreign exchange rates that could be directly influenced by it.

(a)	Selection of scenarios

The Focus Market Readout published by the Central Bank of Brazil (“BACEN”) was used to create the probable scenario for the US$-R$/Euro-R$ exchange rate, the Selic/CDI interest rate and the IPCA interest rate as at March 31, 2025.

According to the Market Readout, US$1 will remain at approximately R$5.92, while the Selic rate should reach 15.00% p.a. at the end of the year 2025. The Selic rate is used as benchmark for sensitivity analysis of the CDI rate. According to the forward market curves, the Euro is expected to stay around R$7.47, and the Mexican Peso is expected to remain near R$0.33.

Since the Market Readout report does not include consensus forecasts for the SOFR interest rates, the projection of the U.S. Federal Reserve for the Federal Funds Rate was used, which was published in March 2025, in comparison with the current level of the Federal Funds rate on March 31, 2025.

For each variable analyzed in the sensitivity analysis, the Company has considered estimating annualized variations corresponding to 1 and 3 standard deviations of monthly averages of the last five years. They are equivalent to approximately 15.866% and a 0.135% probability of occurrence for the reasonably possible and possible scenarios, respectively. Then, these changes are applied to the current market levels of each variable.

18.6 Cash flow hedge

The Company designates certain derivative financial instruments and financial liabilities of debts in US dollars as hedging instruments to protect against cash flow variability. Cash flow hedges are intended to protect against exposure to cash flow variability that is attributable to foreign exchange risk associated with highly probable future sales.

Derivatives designated for hedgeaccounting – Braskem S.A.

(i) US$ call and put options

On March 31, 2025, the Company holds a total notional amount of put options of US$0.96 billion (R$4.68 billion), with an average strike price of 4.84 R$/US$ and notional amount of call options of US$0.66 billion (R$4.68 billion), with an average strike price of 7.09 R$/US$. The operations have a maximum term of 18 months.

As the object of hedge, future sales in Brazilian real pegged to U.S. dollar were designated, with the months of recognition always coinciding with those of the options. The future elements of forward exchange contracts are excluded from the designation of hedge instrument and are separately recorded as hedging cost, recognized in the OCI.

(ii) US$ CDI Swap Agreements

In 2018, the Company contracted foreign exchange derivatives operations ("swaps") totaling R$1.27 billion, with annual maturities from January 2019 to January 2025, replacing the CDI-linked maturity variations with those linked to the US dollar. These operations were designated to cash flow hedge, where the hedging instruments are foreign exchange derivatives, and the hedged objects are highly probable future revenues in the domestic market subject to fluctuations in R$/US$ price.

Accordingly, the mark-to-market adjustment in the effective hedge portion will be recorded in equity in OCI and will be recognized in financial results upon the realization of each of the objects.

(iii) US$ Swap Agreements - CRA

In 2022, the Company entered into swap agreements with semiannual maturities over the next 10 years, starting in March 2022, replacing the variation of the IPCA with the variation of the US dollar. These operations were designated for cash flow hedge accounting, in which hedge instruments are foreign exchange derivatives and the hedge objects are highly probable future revenue subject to the R$/US$ exchange rate.

Accordingly, the mark-to-market adjustment in the effective hedge portion will be recorded in equity in OCI and will be recognized in financial results upon the realization of each of the hedge objects.

In the period ended as of March 31, 2025, the Company did not identify any events indicating that the book value of these deferred taxes exceeds the recoverable amount.

(e)	International Tax Reform – Pillar two

The Company is within the scope of the International Tax Reform – Pillar two model rules and operates in Netherlands and Germany, which have already effective new legislation, from January 1, 2024, however, the Company only recorded additional income taxes in the Netherlands, where its effective rate is less than 15%.

No other jurisdiction in which the Company has operations has enacted the new legislation and, furthermore, the effective rate in these regions is greater than 15%. Therefore, the Company does not expect any additional impact on its financial statements.

The Company applied mandatory temporary exemption to the recognition of deferred taxes for the impacts of the complementary tax rate and assessed the new disclosures required about Pillar Two exposures.

---	---

In the context of allegations of undue payments in connection with Operation Car Wash in Brazil, the Company hired external experts in investigation to conduct an independent investigation into such allegations (“Investigation”) and to report their findings.

In December 2016, the Company entered into Leniency Agreements with the Federal Prosecution Office (“MPF Agreement”) and with U.S. and Swiss authorities (“Global Settlement”), in the amount of US$957 (R$3.1 billion, at the time), which were duly ratified. Further, the Company engaged in a process of cooperation and negotiation with the Ministry of Transparency and the Office of The Federal Controller General (“CGU”) and the Office of the Attorney General (“AGU”), which culminated in the execution of the leniency agreement with such authorities on May 31, 2019 (“CGU/AGU Agreement” and, jointly with the Global Settlement, “Agreements”), which addresses the same facts that are the subject of the Global Settlement and provides for an additional disbursement of R$410 due to the calculations and parameters adopted by CGU/AGU. In addition, in 2019, the State Prosecution Office of Bahia and the State Prosecution Office Rio Grande do Sul adhered to the MPF Agreement, and no additional payments by the Company are expected.

In August 2023, the Company was notified by the CGU about the end of the monitoring period of the Company’s integrity program, and also presented the closing of the monitorship.

In February 2024, a decision was rendered by the Federal Supreme Court, within the scope of the Action against the Violation of a Constitutional Fundamental Right (“ADPF”) No. 1051, determining the renegotiation of leniency agreements. In December 2024, the Company entered into an Amendment to the Leniency Agreement to adjust the payment schedule and other obligations and conditions, as outlined below:

(i)	2025: R$35
(ii)	2026: R$35
---	---
(iii)	2027: R$55

In January 2025, the amount scheduled for the current year was settled, with payment of the inflation-adjusted amount at R$37.

The CGU/AGU Amendment is pending approval by the Federal Supreme Court (STF), in the ADPF records.

As a result of the amendment, the Company recognized a reversal of R$112 in the provision amount of the leniency agreement.

As of March 31, 2025, the balance payable adjusted by the SELIC rate is R$615 (2024: R$636), of which R$86 is recorded under current liabilities (2024: R$ 85) and R$529 is recorded under non-current liabilities (2024: R$551).

23 Geological event - Alagoas

In May 2019, the Geological Survey of Brazil (“CPRM”) issued a report, indicating that the geological phenomenon identified in certain neighborhoods of the municipality of Maceió, Alagoas, could be related to the rock salt well exploration activities developed by Braskem. The salt mining operation, from this moment on, was fully ended by the Company.

Since then, the Company has been devoting its best efforts to understand the geological event, its possible effects on surfaces, stability of rock salt cavities and in carrying out precautionary measures to ensure public safety. The results arising from the understanding of the geological event are being shared with the Brazilian National Mining Agency (“ANM”) and other pertinent authorities.

As a result of the geological phenomenon, negotiations were conducted with public and regulatory authorities that resulted in the Agreements executed, including the following agreements in progress:

i) Agreement to Support the Relocation of People in Risk Areas (“Agreement for Compensation of Residents"), entered into with State Prosecution Office (“MPE”), the State Public Defender’s Office (“DPE”), the Federal Prosecution Office (“MPF”) and the Federal Public Defender’s Office (“DPU”), which was ratified by the court on January 3, 2020, adjusted by its resolutions and subsequent amendments, , which establish cooperative actions for relocating residents from risk areas, defined in the Map of Sectors of Damages and Priority Action Lines by the Civil Defense of Maceió (“Civil Defense Map”), as updated in December 2020 (version 4), and guaranteed their safety, which provides support, under the Financial Compensation and Support for Relocation Program (“PCF”) implemented by Braskem to the population in the areas of the Civil Defense Map. Following ratification by the courts of the Agreement for Compensation of Residents, the Public-Interest Civil Action for Resident Reparation was dismissed;

ii) Agreement to Dismiss the Public-Interest Civil Action on Socio-Environmental Reparation (“ACP Socio-Environmental Reparation”) and the Agreement to define the measures to be adopted regarding the preliminary injunctions of the Public-Interest Civil Action on Socio-Environmental Reparation (jointly referred to as “Agreement for Socio-Environmental Reparation”), signed with the MPF with the MPE as the intervening party, on December 30, 2020, in which the Company mainly undertook to: (i) adopt measures to stabilize and monitor the subsidence phenomenon arising from salt mining; (ii) repair, mitigate or compensate possible environmental impacts and damages arising from salt mining in the Municipality of Maceió; and (iii) repair, mitigate or compensate possible socio-environmental impacts and damages arising from salt mining in the Municipality of Maceió. Additionally, the agreement provides for the allocation of the amount of R$300 for compensation for social damages and collective pain and suffering and for any contingencies related to actions in vacated areas and urban mobility actions. Following ratification by the courts of this agreement, the Public-Interest Civil Action for Socio-environmental Reparation was dismissed;

iii) Agreement for Implementation of Social and Economic measures for Requalification of the Flexal Area (“Flexal Agreement”), entered into with MPF, MPE, DPU and the Municipality of Maceió and ratified on October 26, 2022, by the 3^rd^ Federal Court of Maceió, which establishes the actions to requalify the Flexal region, payment of compensation to the Municipality of Maceió and indemnifications to residents in the region; and

iv) Global Agreement with the Municipality of Maceió (“Global Agreement”) ratified on July 21, 2023 by the 3^rd^ Federal Court of Maceió, which establishes, among other things: (a) payment of R$1.7 billion as indemnity, compensation and full reimbursement for any property and non-property damages caused to the Municipality of Maceió; (b) adherence of the Municipality of Maceió to the terms of the Socio-environmental Agreement, including the Social Actions Plan (PAS).

The Management of Braskem, based on its assessment and that of its external advisors, considering the measures recommended on technical studies in the short and long-term and the existing information and refined estimates of expenses for implementing several measures connected with the geological event in Alagoas, presents the following changes in the period:

		Parent company
		Consolidated
	Mar/25	Dec/24
Balance at the beginning of the year	5,570	5,240
	-	-
Provisions (reversal) (*)	(47)	2,237
Payments and reclassifications (**)	(468)	(2,052)
Realization of present value adjusment	25	145
	-	-
Total	5,080	5,570
Current liability	2,044	2,436
Non-current liability	3,036	3,134
Total	5,080	5,570

(*) i) The reversal of the provision during the period primarily refers to the update of the present value adjustment due to the remeasurement of the estimated disbursement. In the fiscal year 2024, it is mainly explained by the update of cost estimative relating to the adjustments to the plan for closing the mining wells, implementation and advancement in the maturity of projects, initiatives and programs present in the actions fronts in Alagoas; and ii) inflation adjustment of R$4 (2024: R$114) reported under Financial expenses;

(**) Of this amount, R$286 (2024: R$1,819) refers to payments made and R$182 (2024: R$233) was reclassified to Other liabilities, which totals a balance of R$431 (2024: R$478) referring to accounts payable for the Geological event – Alagoas.

The amounts included in the provision are segregated into the following action fronts:

a. Support for relocating and compensating: Refers to actions to support for relocating and compensating for the residents, business and real state owners of properties located in the Civil Defense Map (version 4 updated in December 2020), including establishments that require special measures for their relocation, such as hospitals, schools and public equipment.

This action has a provision of R$765 (2024: R$997) that comprises expenses related to relocation actions, such as relocation allowance, rent allowance, household goods transportation, negotiation of individual agreements for financial compensation and indemnities related to establishments that require special measures for their relocation.

b. Actions for closing and monitoring the salt cavities,environmental actions and other technical matters: Based on the findings of sonar and technical studies, stabilization and monitoring actions were defined for all 35 existing salt mining areas.

The closure plan of 35 mining areas currently considers the following:

i)	18 cavities are scheduled for priority filling with solid material. To date, 6 cavities<br>have already been filled, 6 cavities are in the filling process, and the remaining 6 cavities are in the preparation and planning activities;
ii)	6 cavities were naturally filled and, therefore, do not indicate, at this moment, the need<br>for additional measures. Cavity 18, which collapsed on December 10, 2023, is awaiting approval by the ANM regarding the technical studies<br>presented that conclude on its natural filling;

| --- | | Braskem S.A. **** Management notes to the parent company and consolidated quarterly information as of March 31, 2025 All amounts in millions of Brazilian Real, except as otherwise stated | | iii) | 11 cavities remain within the salt layer and suitable for pressurization. By the end of 2024, the Company based on the technical note issued by expert consultancy, considered the recommendation of filling these pressurized cavities with solid material, in the long term, over the course of several years to decades, and after the completion of the current filling plan, with the purpose of to achieve a maintenance-free state for the 35 cavities, suitable for the final closure of the field. | | --- | --- |

Note that any need for additional actions is assessed on an ongoing basis by the Company and are based on technical studies prepared by external specialists, whose recommendations may be updated periodically according to the changes in the geological event and knowledge obtained, being submitted to competent authorities and following the execution timeframe agreed under the mine closure plan, which is public and regularly revaluated with ANM. Subsidence is a dynamic process occurring in the area outlined by the priority action lines map and should continue to be monitored during and after the actions envisaged in the closure plan. The results of the monitoring activities will be important to assess the need for potential future actions, with a focus on security and monitoring of stability in the region. Any potential future actions may result in significant additional costs and expenses that may differ from current estimates and provisions.

The provisioned balance amount of R$2,404 (2024: R$2,607) to implement actions for closing and monitoring the salt cavities, environmental actions and other technical matters was calculated based on currently known techniques and the solutions planned for the current conditions of the cavities, including expenses with technical studies and monitoring, as well as environmental actions already identified. The provision amount may be changed based on new information, such as: results of the monitoring of the cavities, progress of implementing the plans to close mining areas, possible changes to be made to the environmental plan, monitoring of the ongoing measures and other possible natural alterations.

Regarding environmental actions, in compliance with the Agreement for Socio-environmental Reparation, Braskem continues implementing the actions established in the environmental plan approved by the MPF and sharing the results of its actions with the authorities.

As one of the results of the collapse of cavity 18, as agreed in the Socio-Environmental Reparation Agreement, the specific Environmental Diagnosis to evaluate potential impacts caused by the collapse of said cavity, conducted by specialized firm, was completed. The report was submitted to the authorities, and their opinion is awaited concerning the recommended additional actions, which are related to evaluations and monitoring that complement the ongoing environmental plan.

**c. Social and urban measures:**Refers to actions in compliance with social and urban measures, under the Agreement for Socio-environmental Reparation signed on December 30, 2020, for the adoption of actions and measures in vacated areas, urban mobility and social compensation actions, indemnification for social damages and collective pain and suffering and possible contingencies related to the actions in the vacated areas and urban mobility actions. To date, of the 11 projects defined for urban mobility, 6 have already been completed, 2 are in progress and the remaining projects are in the planning stage. Regarding the Social and Urban Action Plan ("PAS"), of the 30 actions under Braskem's responsibility, 5 are under implementation, 10 are in the planning stage, and 15 are yet to be planned. The balance of the provision is R$998 (2024: R$1,141).

d. Additional measures: Refers to actions regarding: (i) actions related to the Technical Cooperation Agreements entered into by the Company; (ii) expenses relating to communication, compliance, legal services, etc.; (iii) additional measures to assist the region and maintenance of areas, including actions for requalification and indemnification directed to Flexais region; and (iv) other matters classified as a present obligation for the Company, even if not yet formalized. The balance of additional measures described in this item totals R$913 (2024: R$825).

| 51 |  | ![](bakitr1q256k_004.jpg) |

| --- | --- | --- |

| ![](bakitr1q256k_003.jpg) |

The provisions of the Company are based on current estimates and assumptions and may be updated in the future due to new facts and circumstances, including, but not limited to: changes in the execution time, scope and method and the success of action plans; new repercussions or developments arising from the geological event, including possible revision of the Civil Defense Map; studies that indicate recommendations from specialists, including the Technical Monitoring Committee, according to Agreement for Compensation of Residents, and other new developments in the matter.

The actions to repair, mitigate or offset potential environmental impacts and damages, as provided for in the Socio-environmental Reparation Agreement, were defined considering the environmental diagnosis prepared by a specialized and independent company. After the conclusion of all discussions with authorities and regulatory agencies, as per the process established in the agreement, an action plan was agreed to be part of the measures for a Plan to Recover Degraded Areas (“PRAD”).

On May 21, 2024, the final report of the Parliamentary Investigative Committee ("CPI"), set up by the Senate on December 13, 2023, was approved, with the purpose of investigating the effects of the Company's socio-environmental legal liability related to the geological event in Alagoas. On this date, the aforementioned CPI was declared closed, with the subsequent submission of the final report to the appropriate institutions.

There are also administrative proceedings related to the geological event in Alagoas in progress before the Federal Accounting Court ("TCU") and the Securities and Exchange Commission of Brazil ("CVM").

In October 2024, the Company became aware of the conclusion of the Federal Police of Alagoas investigation that had been ongoing since 2019. The investigation files were forwarded to the Public Prosecutor's Office for evaluation, which required additional measures. The Company reiterates that it has always been at the disposal of authorities and has been providing all information related to salt mining exploration over the course of the investigation.

The Company has been making progress in negotiations with public entities about other indemnification requests to understand them better, which may lead to future agreements. Although future disbursements may occur as a result of said negotiations, as of the reporting date, the Company is unable to predict the results and timeframe for concluding these negotiations or its possible scope and the total associated costs in addition to those already provisioned for.

It is not possible to anticipate all new claims related to damage or other nature, that may be brought by individuals or groups, including public or private entities, that understand they suffered impacts or damages somehow related to the geological phenomenon and the relocation of people from risk areas, as well as new notices of violation or administrative penalties of diverse natures. Braskem continues to face and could still face administrative procedures and various lawsuits filed by individuals or legal entities not included in the PCF or that disagree with the financial compensation offer for individual settlement, as well as new collective actions and new lawsuits filed by public utility concessionaires, entities of the direct or indirect administration of the State, Municipalities or Federal level. Therefore, the number of such actions, their nature or the amounts involved cannot be estimated at this moment.

Consequently, the Company cannot eliminate the possibility of future developments related to all aspects of the geological event in Alagoas, the relocation process and actions in vacated and adjacent areas, so the expenses to be incurred may significantly differ from its estimates and provisions.

| --- | | Braskem S.A. **** Management notes to the parent company and consolidated quarterly information as of March 31, 2025 All amounts in millions of Brazilian Real, except as otherwise stated | | 2) | Public-Interest Civil Action - Request for Indemnification for Additional Collective Pain and Suffering | | | | --- | --- | --- | --- | | | Plaintiff: Alagoas State Public Defender’s Office | | | | | In March 2024, the Company became aware of the Public-Interest Civil Action filed by the Public Defender’s Office (DPE) which, among others, challenges clause 69 of the Socio-environmental Agreement (payment of R$150 for collective pain and suffering), alleging that there are facts subsequent to the execution of the agreement that would have caused additional pain and suffering. DPE requested a preliminary injunction: (i) to suspend clause 58, paragraph two, of the Socio-environmental Agreement in order to reject the possibility of returning the area to Braskem; (ii) to prohibit the sale of the PCF area until a final and unappealable decision is made on the subject of the claim, considering that the assets acquired through the Program for Financial Compensation must not be sold or pledged. On April 12, 2024, these preliminary claims were rejected by the court. In the merit, the claims include: (i) the loss of all properties that are the subject of PCF, with the possibility of returning the area to the victims or to the public domain, besides ordering Braskem to pay, as compensation for collective and social pain and suffering, the same amount paid by Braskem for material damages; (ii) condemning Braskem, as compensation for existential damages, for the loss of all properties that are the subject of the PCF; (iii) condemning Braskem for “illicit profit,” with the loss of properties that are the subject of the PCF, and the payment of amounts obtained by the Company through its alleged illicit conduct (to be calculated in the liquidation of the award); (iv) issue of subpoena to the Investor Relations Officer, for the purposes of regulatory obligations, with the publication of material fact notice. | 166 | 162 | | 3) | Public-Interest Civil Action - Refusal of insurance within the scope of Housing Financial System (“SFH”) | | | | | Plaintiff: Federal Public Defender’s Office | | | | | In November 2021, the Company became aware of the Public-interest civil action to question the denial of necessary insurance for contracts under the SFH to acquire properties located within a radius of 1 km outside the risk area defined by the version 4 map of Civil Defense authorities, which is the subject matter of the Residents PCA agreement – See item (i). Insurers linked to SFH, financial agents, the regulatory agency and Braskem are the defendants. The main claim is only against the insurers, financial agents and the regulatory agency on the grounds that the refusal to contract the insurance is abusive and has no technical or legal grounds. There is a secondary and eventual claim to sentence Braskem to pay indemnification in an amount to be settled in the future, if the judge understands that the refusal somehow has grounds in the subsidence phenomenon. On January 10, 2024, a decision was rendered partially ordering the insurance companies to: (i) refrain from applying the safety margin beyond the risk area defined by the Civil Defense and engaging in unfair pricing and increases to avoid contracting insurance coverage for properties out of and next to the risk area, declaring that there were no denials/decreases in the insurance coverage based exclusively on the safety margin, (ii) call everyone who is interested to reassess the request for housing insurance. Braskem was not found guilty, and insurance companies filed an appeal against the decision, which is still pending. It is not possible to estimate the indemnification amount, which will depend on the evidence of damages submitted by people whose insurance was denied. | - | - |

Through this lawsuit, the DPE seeks, among other claims, the inclusion of residents of Flexais region, who choose to adhere the PCF, program created under the agreement in ACP (Reparation for Residents), with consequent reallocation of these residents and compensation for moral and material damages in parameters specified in the ACP. As injunction relief, DPE also requested, that the Municipality of Maceió and Braskem initiated the registration of all residents who requested to be relocated and their concomitant inclusion in the PCF, or, alternatively, requested the freeze of Braskem bank accounts in the amount of R$1.7 billion, to guarantee the compensation for moral and material damages to residents of the Flexais region. The injunction relief requests were rejected by the trial and appellate courts. On January 19, 2024, a decision was rendered, judging partially valid the requests made by the DPE. The Company, the DPE/AL, the Alagoas State Government and the Federal Government filed appeals against this decision. The effects of the lower court's decision are suspended until the appeals are adjudicated. | 2,189 | 2,137 | | 5) | Public-Interest Civil Action - Fishermen Reparation | | | | | Plaintiffs: Federation of Fishermen of the State of Alagoas (“FEPEAL”) and National Confederation of Fishermen and Aquaculturists (“CNPA”) | | | | | In August 2023, the Company became aware of the Public-Interest Civil Action filed by FEPEAL and CNPA (jointly the “Associations”) against the Company, seeking compensation for material damages (damages and loss of profit) and homogeneous individual and collective morals damages for the Associations and each of the alleged 8,493 affected fishermen represented by the Associations. As a preliminary measure, the Associations requested, among other claims, that the Company provision sufficient funds to guarantee the compensation of fishermen included in the public-interest civil action, and also publishing a material fact notice to the shareholders. These requests were rejected by the Courts. Among other requests, the Associations claim the payment of: (i) compensation for (a) individual and homogeneous moral damages suffered, in the amount of R$50,000 and (b) material damages in the form of individual and homogeneous loss of profits, in the amount of R$132,000 in both cases for each of the allegedly affected fishermen; (ii) compensation for collective moral damages for the Associations, in the amount of R$100,000; (iii) compensation for collective material damages to the Associations, in the amount of R$750,000; and (iv) attorney fees in the amount of 20% on the value of the award. The Company filed an answer. The action was suspended by the TRF5 pending the judgment of the Interlocutory Appeal filed by Braskem, which challenges the legitimacy of the representation of the plaintiff institutions. | 1,812 | 1,767 | | 6) | Action against the Violation of a Constitutional Fundamental Right (ADPF) | | | | | Plaintiff: Alagoas State Governor | | | | | On December 18, 2023, the Company was informed of the Action against the Violation of a Constitutional Fundamental Right (ADPF) filed before the Federal Supreme Court due to some clauses of the agreements entered into out-of-court and ratified in the records of the cases 0803836-61.2019.4.05.8000 (ACP Reparation for Residents, 0806577-74.2019.4.05.8000 (ACP Social-Environmental Reparation) and 0812904-30.2022.4.05.8000 (Flexal Agreement), which deal with the settlement to the Company, as well as the acquisition and exploration of vacant properties. On June 24, 2024, the judge rapporteur issued a decision denying the ADPF continuance. The plaintiff filed an appeal against this decision. It is not possible to assign a contingency amount to this lawsuit, which has illiquid claims, aiming at the declaration of nullity of specific contractual clauses of the Agreements. | - | - |

The request was denied in lower and appellate courts, given the fulfillment of the obligations undertaken by Braskem. On February 24, 2021, CBTU filed an amendment to the initial request claiming compensation for losses and damages in the amount of R$222 and for moral damages in the amount of R$0.5, as well as the imposition of obligations, including the construction of a new rail line to substitute the stretch that passed through the risk area. Braskem entered into a memorandum of understanding with CBTU to reach a mutual solution and suspend the lawsuit during the negotiation period. Moreover, a procedural legal transaction was presented, approved by the court, which provided for the suspension of lawsuit, enabling the continuity of negotiations. | 1,500 | 1,492 | | 8) | Action for Damages - Pinheiro District Property | | | | | Plaintiff: Construtora Humberto Lobo | | | | | In July 2019, the Company became aware of the action for damages claiming that the plaintiff suffered damages and loss of profits due to an agreement to purchase from Braskem a property in the District of Pinheiro. Said agreement was terminated by Braskem due to lack of payment by the Contractor. Nevertheless, the Contractor claims that Braskem omitted information on the existence of structural problems in the deactivated salt mining wells located on said property.

24.2 Share rights

Preferred shares carry no voting rights, but they ensure priority, non-cumulative annual dividend of 6% of their unit value, according to profits available for distribution. The unit value of the shares is obtained through the division of capital by the total number of outstanding shares. As common shares, only class “A” preferred shares will have the same claim on the remaining profit that exceeds the minimum mandatory dividend of 6% and will be entitled to dividends only after the priority dividend is paid to preferred shareholders. Only class “A” preferred shares also have the same claim as common shares on the distribution of shares resulting from capitalization of other reserves. Class “A” preferred shares can be converted into common shares upon resolution of majority voting shareholders present at a General Meeting. Class “B” preferred shares can be converted into class “A” preferred shares at any time, at the ratio of two class “B” preferred shares for one class “A” preferred share, upon a simple written request to the Company, provided that the non-transferability period provided for in specific legislation that allowed for the issue and payment of such shares with tax incentive funds has elapsed.
