Quarterly information for the period ended March 31, 2026 (Free Translation into English from the Original Previously Issued in Portuguese) Braskem S.A. KPMG Auditores Independentes Ltda. Rua Verbo Divino, 1400 - Conjunto Térreo ao 801 – parte, Chácara Santo Antônio, CEP 04719-911, São Paulo - SP Caixa Postal 79518 - CEP 04707-970 - São Paulo - SP - Brasil Telefone 55 (11) 3940-1500 kpmg.com.br Report on the review of interim financial information (ITR) (A free translation of the original report in Portuguese, as filed with the Comissão de Valores Mobiliários - CVM, for the individual interim financial information prepared in accordance with the Technical Pronouncement CPC 21 (R1) - Demonstração Intermediária, and for the consolidated interim financial information prepared in accordance with the Technical Pronouncement CPC 21 (R1) - Demonstração lntermediária and 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, 2026, which comprises the statement of financial position as at March 31, 2026 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 lntermediária 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 lnformações lntermediárias Executada pelo 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. 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. Emphasis - Material uncertainty related to going concern We draw attention to Note 1 of the interim financial information, which indicates that according to the balance sheet as of March 31, 2026, current liabilities exceeded its total assets by R$ 2,714 million in the parent company and R$ 10,718 million in the consolidated, and equity was negative by R$ 15,736 million in the parent company and R$ 16,233 million in the consolidated. Management's plans regarding this matter are described in the aforementioned note. As stated in Note 1, these events or conditions, along with other matters as set forth in Note 1, indicate that a material uncertainty exists that may cast significant doubt on the Company’s ability to continue as a going concern. Our conclusion is not modified in respect of this matter. 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, 2026, 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.

Management notes to the parent company and consolidated quarterly information as of March 31, 2026 All amounts in millions Reais, except as otherwise stated The petrochemical plants are dedicated to producing thermoplastic resins, such as polyethylene (“PE”), polypropylene (“PP”), polyvinyl chloride (“PVC”) and other basic petrochemicals. Economic and financial condition of Braskem Idesa and substantial doubt about its ability to continue as going concern The financial statements of Braskem Idesa, included in this quarterly information, have been prepared on a going concern basis, which assumes the company will continue to operate, and that its assets will be realized and its liabilities and commitments settled in the normal course of Braskem Idesa's business. The deterioration of Braskem Idesa’s economic and financial condition is set within an adverse operating environment observed over recent years, primarily characterized by a significant compression of petrochemical spreads, resulting from a prolonged industry downturn, driven by weaker-than-expected global demand and global oversupply, largely attributable to China and the USA, as well as an increase in the reference price of ethane related to the original contract with the local supplier, which is the primary raw material in its production process. In addition, Braskem Idesa faced material constraints on the volume of locally supplied ethane (in Mexico) which limited its operating flexibility, reduced capacity utilization rates, and increased its exposure to imported feedstocks and higher logistics costs. Taken together, these factors resulted in operating cash generation consistently below the level required to support Braskem Idesa’s existing indebtedness, contributing to liquidity imbalance and an increased financial risk profile. As a result, in September 2025, Braskem Idesa, announced that, with the objective of reviewing its current capital structure and liquidity conditions, it had engaged financial and legal advisors (Lazard Inc., Cleary Gottlieb Steen & Hamilton LLP, and Sainz Abogados) to support Braskem Idesa in assessing a broad range of economic and financial alternatives. In December 2025, Braskem Idesa provided certain holders of the 2029 and 2032 bonds (the ad-hoc group or “AHG”) with non-public information in the context of a potential reorganization of its capital structure. After the parties were unable to reach a consensus on the proposal submitted by Braskem Idesa, such information was subsequently disclosed to the market, including the discussion materials and the proposals presented. In 2025, Braskem Idesa secured a Term Loan totaling R$939 million (US$180 million), of which R$674 million (US$129 million) had been disbursed by March 2026. Of the total amount used, R$177 (US$34) will mature in December 2026, while the remaining R$497 (US$95) will mature in 2029. In November 2025 and February 2026, Braskem Idesa defaulted on interest payments related to the bonds 2029 and 2032, respectively. As of March 2025, the outstanding balance of such interest, recorded in current liabilities, amounted to R$576 (US$110). As a result of this nonpayment, the full outstanding balance of interest and principal of the bond may be accelerated by the bondholders, subject to the applicable contractual quorum. Since the decision to accelerate the debt is not under Braskem Idesa’s control and it does not have the ability to defer these payments for at least 12 months after the reporting date, the balance of this obligation was reclassified to current liabilities, as well as other borrowings that contain cross default clauses in their contracts. The Company’s remaining balances of borrowings and debentures were not impacted. Finally, in light of the context presented, Braskem Idesa remains engaged in negotiations with the AHG, with a view to reorganizing its capital structure through judicial measures (e.g., Chapter 11 under U.S. Law), which may have potential impacts on the Company as well on the shareholding control of Braskem Idesa. Braskem S.A. Management notes to the parent company and consolidated quarterly information as of March 31, 2026 All amounts in millions Reais, except as otherwise stated These events and conditions indicate the existence of a substantial doubt about the Braskem Idesa’s ability to continue as going concern. Notwithstanding the substantial doubt, Management believes that the use of the going concern assumption remains appropriate in the preparation of this quarterly information, considering that the Company and its subsidiary continue to operate, with ongoing activities and initiatives underway aimed at financial restructuring and the restoration of liquidity. Accordingly, this quarterly information does not include adjustments that might be required if its subsidiary was unable to continue operating on a going concern basis. Economic and financial condition of the Company and substantial doubt about its ability to continue as going concern The quarterly information have been prepared under the going concern assumption, which presumes the continuity of operations and the realization of assets as well as the settlement of liabilities and commitments in the ordinary course of business of the Company. As of March 31, 2026, the statement of financial position presents negative net working capital (defined as total current assets less total current liabilities) amounting to R$10,718 (2025: negative amount ofR$9,770) in the Consolidated. The net working capital balances are negative as a result of the effects of Braskem Idesa's financing, which has been reclassified under current liabilities. Net working capital is negative by R$2,714 (2025: negative amount of R$3,090) in the Parent Company. Shareholders’ equity is negative by R$16,233 (2025: negative amount of R$16,502) in the Consolidated and negative by R$ 15,736 (2025: negative amount of R$16,147) in the Parent Company. Borrowings and debentures are predominantly due in the long term, except for the reclassification effect related to Braskem Idesa’s borrowings, with over 94% denominated in US dollars, consistent with the Company's Financial Policy. Braskem believes that this US dollar exposure is adequate 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. As communicated to the market, in September of 2025, the Company has engaged financial and legal advisors — Lazard Inc., Cleary Gottlieb Steen & Hamilton LLP, and E. Munhoz Advogados — to support it in preparing a diagnosis of economic-financial alternatives to reorganize its capital structure. Consistent with its cash management, in October 2025, the Company has withdrawn the available stand-by credit facility in the amount of US$1.0 billion (R$: 5,350). The credit facility matures in December 2026. At the end of 2025, the Company's global credit ratings assigned by the rating agencies Fitch Ratings and S&P Global were CC and CCC-, with no outlook and negative outlook, respectively. In this context, there was an increase in the balances of reserve accounts associated with the fulfillment of certain contractual obligations (see Note 5), and guarantees were provided for specific energy contracts. As of March 31, 2026, no provisions were recorded, nor was the Company considered to be in default under these energy contracts. During the last year, there was a decrease in the availability of certain payment agreements with financial institutions and forfaiting agreements. The Company had obtained access to a set of actions that contributed to strengthening its cash position for the coming years, including, among others: PRESIQ: In 2025, aiming to mitigate the effects of the termination of the Special Regime for the Chemical Industry (“REIQ”) and preserve the competitiveness of the chemical industry, which is a strategic and essential sector for the Brazilian economy, Law No. 15,294/25 was enacted, establishing the Special Program for the Sustainability of Braskem S.A. Management notes to the parent company and consolidated quarterly information as of March 31, 2026 All amounts in millions Reais, except as otherwise stated the Chemical Industry (“PRESIQ”). The program introduces an incentive regime aimed at stimulating the Brazilian chemical industry, effective from January 1, 2027, through December 31, 2031, in two modalities: (i) industrial, related to the acquisition of certain chemical products, and (ii) investment, related to the expansion or modernization of installed capacity. PE Antidumping: In November 2024, the Foreign Trade Office of Brazil ("SECEX") published the Circular Letter No. 63/2024, initiating an investigation to assess the existence of dumping in exports of PE resins from the United States and Canada to Brazil, as well as the resulting injury to the domestic industry. In August 2025, the Executive Management Committee of the Foreign Trade Chamber (“GECEX”/ “CAMEX”) approved the application of a provisional antidumping duty. In April 2026, GECEX Resolution No. 876/2026 was published, concluding the investigation and imposing definitive antidumping duties, for a five-year period, on imports of polyethylene PE resins originating from the United States and Canada. List of cyclical trade imbalances: In October 2025, GECEX approved, through GECEX Resolution No. 800/2025, the maintenance of the 20% import duty rate applicable to PE, PP, and PVC resins market by the Company, effective through October 16, 2026, upon their inclusion in the List of Temporary Tariff Increases for Cyclical Trade Imbalances. These measures are strategic, as they contribute to preserving the Company’s competitiveness in the domestic market by mitigating the impacts of unfair competition and imports at artificially reduced prices. Management assessed, in a comprehensive manner, the internal and external factors capable of, eventually, affecting the going concern assumption. Based on available information and the projections set forth in the approved business plan, Management identified a high level of cash utilization over the assessment horizon, considering both existing cash balances and projected operating-cycle inflows. Key elements considered include: • The prolonged downturn cycle in the petrochemical industry, with structurally compressed spreads; • Cash consumption associated with debt service, particularly recurring interest payments; • Cash requirements related to the obligations arising from the Geological Event in Alagoas; • Cash requirements for the maintenance of operating assets, essential for ensuring operational continuity and safety; • Credit rating downgrade; and • Maturity of the US$1.0 billion -stand-by facility in December 2026, requiring a significant cash outflow, if not renewed. These factors, as reflected in the approved business plan, indicate increasing pressure on liquidity and guide Management’s actions aimed at continuously adjusting the Company’s financial position to the current challenges faced by the global chemical industry, as described below. Measures to strengthen financial resilience and capital structure reorganization Among the initiatives currently under development, the planned reorganization of the capital structure is noteworthy, as it depends on factors beyond the Company's exclusive control. The assessment process for this alternative began in the second semester of 2025, when the Company disclosed to the market the engagement of specialized financial and legal advisors to support a comprehensive diagnosis of the available economic‑financial options, with a focus on strengthening liquidity in the capital structure. Braskem S.A. Management notes to the parent company and consolidated quarterly information as of March 31, 2026 All amounts in millions Reais, except as otherwise stated The Company and its specialized financial and legal advisors have been progressing in a structured manner in the formulation of a comprehensive capital structure reorganization plan in negotiations with the creditors’ advisors. Regulatory measures In March 2026, Complementary Law No. 228 was enacted, providing for the increase of the benefit under the REIQ from 0.73% to 5.8%. This benefit corresponds to PIS and Cofins credits levied on feedstocks used by the chemical and petrochemical industries, which may be offset against federal taxes. The benefit will have a sector‑wide budget limit of R$2 billion and will remain in effect from March through December 31, 2026, and beginning in April, will be subject to a 10% reduction, as provided for in the applicable legislation. For the year 2026, a sector cap of R$1.1 billion was also established for the use of the incremental credit (“REIQ Investimentos”) of 1.5%, which is linked to the execution of investment projects. Potential Transaction involving a change in Braskem’s controlling shareholder In December 2025, Novonor informed the Company of the execution of a binding agreement between a FIDC managed by Vórtx Capital and advised by IG4 Sol Ltda., and Novonor’s creditor banks, for the acquisition of all loans secured by shares issued by the Company and held by NSP Investimentos S.A., as well as the signing of an exclusivity agreement for negotiating a potential corporate transaction involving such shares (the “Transaction”). On December 23, 2025, the Transaction was submitted to the Administrative Council for Economic Defense (“CADE”) for clearance by the competition authority. In February 2026, Petrobras informed that it would not exercise its preemptive rights, and, subsequently, on 25th of March 2026, the CADE’s General Superintendence- approved the Transaction without restrictions. The Transaction has also already been approved by all relevant antitrust authorities required for the consummation of the operation. In April 2026, the Company received notifications from Novonor S.A., NSP Investimentos S.A., and Shine I Fundo de Investimento em Participações (FIP) regarding the signing of an agreement for the court-ordered sale of shares issued by the Company, representing approximately 50.1% of its voting capital and 34.3% of its total capital stock. The completion of the transaction is subject to the satisfaction of certain conditions precedent, including court approvals and regulatory consents. Additionally, Petrobras announced that it has sent a notice to Novonor, formally stating its decision not to exercise the Preemptive and Tag Along Rights stipulated in the Company's current Shareholders' Agreement. The FIP also expressed its intention to carry out, jointly with Petrobras, a financial and operational restructuring of the Company. Additionally, a public tender offer for acquisition of shares ("PTO") by the FIP is planned, in accordance with the applicable legislation. In connection with the execution of the Company's share sale agreement, the FIP and Petrobras entered into a new Shareholders' Agreement, which regulates, among other matters, the exercise of joint control over Braskem. The Shareholders' Agreement will become effective and enter into force on the date the Transaction is consummated. These events and conditions indicate the existence of a substantial doubt about the Company's ability to continue as a going concern. The quarterly information does not include any adjustments to reflect possible future effects over the recoverability and classification of assets or amounts and classification of liabilities that may result from material uncertainty related to the Company’s ability to continue operating normally. Braskem S.A. Management notes to the parent company and consolidated quarterly information as of March 31, 2026 All amounts in millions Reais, except as otherwise stated Uncertainties arising from geopolitical conflicts The current global environment remains subject to geopolitical tensions in regions that are strategic for energy markets, particularly the Middle East, which has generated additional volatility in oil, natural gas, and petrochemical feedstock prices. Such events have translated into volatility (increases) in international prices of resins and chemical products sold by the Company, as well as uncertainties regarding potential logistical restrictions on relevant international trade routes. The Company has been continuously monitoring potential scenarios and the associated impacts of these dynamic events, assessing their effects on the conduct of its operations. The quarterly information presented does not reflect material impacts arising from this event. Braskem S.A.

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. Braskem S.A.

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 Fair value total Carrying amount Assets Cash equivalents - 1,138 1,138 1,138 Financial investments - 1,368 1,368 1,368 Trade accounts receivable - 96 96 96 Derivatives - 125 125 125 Energy future agreements - 666 666 666 Total assets 3,393 3,393 3,393 Liabilities Derivatives - 36 36 36 Energy future agreements - 662 662 662 Financing Foreign currency - Bonds 16,935 - 16,935 36,646 Foreign currency - Others - 5,975 5,975 8,475 Local currency - 753 753 1,079 Debentures - 993 993 3,236 Braskem Idesa financing Bond 6,545 - 6,545 11,570 Others - 1,914 1,914 2,536 Total liabilities 23,481 10,334 33,814 64,240 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: Braskem S.A. Management notes to the parent company and consolidated quarterly information as of March 31, 2026 All amounts in millions Reais, except as otherwise stated 35 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: Mar/26 Dec/25 Domestic market Foreign market Total Domestic market Foreign market Total Financial assets with risk classification AAA 1,299 1,146 2,445 1,810 4,111 5,921 AA+ 227 - 227 632 - 632 AA 11 5 16 65 32 97 AA- 16 - 16 27 - 27 A+ 2 2,070 2,072 6 3,604 3,610 A 223 244 467 385 147 532 A- - 517 517 - 891 891 1,778 3,982 5,760 2,925 8,785 11,710 Financial assets without risk classification Other financial assets with no risk (i) 200 86 286 156 - 156 assessment 200 86 286 156 - 156 Total 1,978 4,068 6,046 3,081 8,785 11,866 (i) Investments approved by the Management, in accordance with the Financial Policy. Counterparty risk - Trade accounts receivable As part of its financial risk management, the Company has a specific policy for managing the credit risk of clients, which sets operational parameters and responsibilities for the management of receivables and is enforced by a specialized credit and collection team, which is in charge of the main activities of credit risk management. The Company also has a credit committee responsible for monitoring and supporting the management in the application of internal policies. Considering the expected credit losses, the percentage of trade accounts receivable by risk ratings, representing the Company’s total exposure, was as follows: Braskem S.A.

For the export market, approximately 91% of the portfolio has guarantees, consisting primarily of credit insurance. For the domestic market, approximately 28% of the portfolio has guarantees, mainly suretyships by the partners of counterparties, complemented by credit insurance. 18.4 Market risk The Company, in the normal course of its operations, is exposed to a variety of market risks, mainly related to fluctuations in exchange rates, interest rates and commodity prices, which may affect its current and future cash flows. To mitigate these risks, the Company follows procedures set forth in its financial risk management policy, which aims to identify and monitor exposures, implement actions to protect the organization's results against market volatility, and conduct an organized risk management process. As of March 31, the Company has contracted the following derivative financial instruments, which are used in managing market risk protection: Braskem S.A.

Currently, the only active program refers to the cash flow hedge of TQPM's debt. The details of the outstanding derivatives are provided below: SOFR Swaps - TQPM To mitigate the risk associated with the terminal project, TQPM entered into an interest rate swap to reduce the volatility of highly probable future cash flows indexed to SOFR, related to financial liabilities. The notional amount of the hedge corresponds to 75% of the expected principal of the debt on each interest payment date, under a cash flow hedge structure that covers only the interest payments linked to the variable SOFR component. The economic relationship between the hedging instrument and the hedged item is established based on reference rates, durations, reset dates, maturities, and notional or principal amounts. The main sources of ineffectiveness in these hedge relationships are: • the impact of the counterparty’s and the Company’s own credit risk on the fair value of the swaps, which is not reflected in the changes in the fair value of the hedged cash flows; and • mismatches in repricing dates between the swaps and the underlying borrowings. Braskem S.A. Management notes to the parent company and consolidated quarterly information as of March 31, 2026 All amounts in millions Reais, except as otherwise stated 38 The asset leg of the swap is tied to the 3-month SOFR rate, while the liability leg is fixed at 4.308% per annum. Braskem S.A.'s Derivatives The Company uses derivative financial instruments to hedge against its exposure to fluctuations in the R$/US$ exchange rate. The adopted strategies include transactions involving US dollar call and put options, intended to hedge future sales in Brazilian real that are exposed to the US dollar, as well as entering into swaps. These instruments were designated for hedge accounting of cash flows through December 2025, with the underlying hedge items being future revenues subject to foreign exchange volatility. The effective portion of these instruments, measured up to the date the hedge program was discontinued, was recognized in other comprehensive income (OCI) and will be reclassified to profit or loss as the related hedged cash flows are realized. From January 2026 onwards, changes in the fair value of derivative instruments and their financial effects will be recognized directly in the financial result for the period. 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: As of March 31, 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. 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, 2026. The probable scenario for the Mexican Peso is constructed based on the interpolation of forward exchange rate curves for US$-MXN, using market data. This curve is then converted using the US$-R$ forward curve as a reference. According to the Market Readout, US$1 will remain at approximately R$5.40, while the Selic rate should reach 12,5% p.a. at the end of the year 2026. 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$7.07, and the Mexican Peso is expected to remain near R$0.38. 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 2026, in comparison with the current level of the Federal Funds rate on March 31, 2026. Braskem S.A. Management notes to the parent company and consolidated quarterly information as of March 31, 2026 All amounts in millions Reais, except as otherwise stated 39 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.

Management notes to the parent company and consolidated quarterly information as of March 31, 2026 All amounts in millions Reais, except as otherwise stated 40 18.6 Cash flow hedge By December 2025, the Company has designated financial liabilities of debts denominated in US dollars as hedging instruments to mitigate the exposure to cash flow variability that is attributable to foreign exchange risk associated with highly probable future sales. The purpose of the cash flow hedges was to mitigate the impact of fluctuations in the R$/US$ exchange rate on projected cash flows. Due to the significant uncertainty disclosed in Note 1, management has reassessed, for accounting purposes, whether the 'highly probable transactions' criterion required by IFRS 9 continues to be met for maintaining the hedge accounting program. As a result, hedge accounting for Braskem S.A.'s future revenues will be prospectively discontinued as of December 31, 2025. It should be emphasized that the discontinuation is solely due to the assessment of compliance with applicable accounting requirements in a context of increased uncertainty. This does not change the expectation that these transactions will be carried out, as they remain planned and included in the approved business plan. The remaining balances of the hedge reserve, accumulated in equity, will be reclassified to profit or loss in the same period in which the respective hedged items are realized. The remaining balances in the reserves related to the debt hedge program are: Future exports in US$ - Braskem S.A.

(e) International Tax Reform – Pillar II The Company complies with the rules of the International Tax Reform – Pillar II Model Rules, an initiative of the Organization for Economic Cooperation and Development (“OECD”) in the context of the BEPS (Base Erosion and Profit Shifting) Project. This project aims to combat tax planning practices that result in the erosion of the tax base and the transfer of profits to low-tax jurisdictions. Pillar II establishes a global minimum tax of 15% for each jurisdiction in which the multinational group operates. The Company is subject to Pillar II rules in Germany, Brazil, and the Netherlands. In the third quarter of 2025, the Company fully reversed the provision previously recorded after incorporating tax sparing credits accumulated through December 31, 2023, into the Pillar II calculation of its subsidiary in the Netherlands. Under Pillar II rules, such credits may be recognized as tax expense, resulting in a higher effective tax rate for the subsidiary. As a result of this increase, no additional tax was assessed under the Pillar II rules. The Company does not expect additional impacts on its financial statements resulting from the enactment of the standard in other jurisdictions, since the effective tax rate in these regions is higher than 15%. In addition, the Company applied the temporary exemption from accounting for deferred taxes related to the supplementary tax and assessed the new disclosure requirements on Pillar II exposures, as provided for in the applicable accounting standards. 21 Sundry provisions Consolidated Parent company Mar/26 Dec/25 Mar/26 Dec/25 Leniency agreement (a) 649 673 649 673 Provision for environmental damages 942 972 942 972 Provision for customers rebates 136 189 90 97 Other 101 90 103 90 Total 1,828 1,924 1,784 1,832 Current liabilities 672 711 628 619 Non-current liabilities 1,156 1,213 1,156 1,213 Total 1,828 1,924 1,784 1,832 Braskem S.A.

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 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 CGU/AGU Agreement, and no additional payments by the Company are expected. Since 2016, The Company has already paid R$3,484 distributed as shown below: AGU CGU and MPF DoJ (i) OAG (i) MPF SEC (i) Total Agreements signed with: Amounts paid 1,292 297 407 1,282 206 3484 (i) U.S. Department of Justice (“DoJ”); Swiss Office of the Attorney General (“OAG”) and U.S. Securities Exchange Commission (“SEC”). In August 2023, the Company was notified by the CGU about the end of the monitoring period of the Company’s integrity program, and also presented the closing of the monitorship. In February 2024, a decision was rendered by the Federal Supreme Court (“STF”), within the scope of the Action against the Violation of a Constitutional Fundamental Right (“ADPF”) No. 1051, determining the renegotiation of leniency agreements. In December 2024, the Company entered into an Amendment to the CGU/AGU Agreement to adjust the payment schedule and other obligations and conditions, as outlined below. The MPF agreed to the terms of the Amendment to the CGU/AGU Agreement: (i) 2026: R$ 35 (ii) 2027: R$ 55 (iii) 2028 to 2030: installments of R$ 158 each. In January 2026, the amount scheduled for the current year was settled, with payment of the inflation-adjusted amount at R$42. The CGU/AGU Amendment is pending approval by the 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, 2026, the balance payable adjusted by the SELIC rate is R$649 (2025: R$673), of which R$113 is recorded under current liabilities (2025: R$90) and R$536 is recorded under non-current liabilities (2025: R$583).

(a) Tax (i) PIS/Cofins: The Company was questioned by the Federal Revenue Service about various federal taxes that were offset by non-cumulative PIS and COFINS credits, which were generated by the exclusion of ICMS from the calculation basis of such contributions, as ensured by a final and unappealable court decision. The claims are in the administrative phase. In the first quarter of 2026, the Company received a new decision order, which led to an increase in the contingency to R$718. (ii) Separate Fine - Law No. 10,833/03: In March 2026, the Company was notified of a tax-deficiency notice in which the Federal Revenue Service is imposing a separate fine of 150% on the offsetting of non-cumulative PIS and COFINS credits. These credits were generated due to the exclusion of ICMS from the calculation base of these contributions, as determined by a final and unappealable court decision. As of March 31, 2026, the contingency amount is R$563. Braskem S.A. Management notes to the parent company and consolidated quarterly information as of March 31, 2026 All amounts in thousands Reais, except as otherwise stated 46 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: 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”), with the second amendment to the Agreement being related to the map issued 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 social and urban impacts and damages arising from salt mining in the Municipality of Maceió. 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, which establishes the actions to requalify the Flexal region, payment of compensation to the Municipality of Maceió and indemnifications to residents in the region; iv) Global Agreement with the Municipality of Maceió (“Global Agreement”) ratified on July 21, 2023, which establishes, among other things: (a) payment of R$1.7 billion as indemnity, compensation and full reimbursement for any property and non-property damages caused to the Municipality of Maceió; and (b) adherence of the Municipality of Maceió to the terms of the Socio-environmental Agreement, including the Social Actions Plan (“PAS”); and Braskem S.A. Management notes to the parent company and consolidated quarterly information as of March 31, 2026 All amounts in thousands Reais, except as otherwise stated 47 v) Instrument of Agreement with the State of Alagoas (“State Agreement”), executed on November 10, 2025, which provides, among other terms: (a) a total amount of R$ 1.2 billion as compensation, indemnification, and/or reimbursement to the State of Alagoas for the full reparation of all material and non-material damages suffered by the State; (b) grants the Company a full release from any liability for damages arising from and/or related to the geological event in Alagoas, including the dismissal of the State of Alagoas’ Action for Damages. Of the total R$1.2 billion established in the agreement, R$139 million (adjusted to current value) have already been paid. The outstanding balance will be paid in 10 variable annual installments, which will be adjusted mainly after 2030, taking into account the Company's ability to pay. 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: 2026 2025 Balance at the beginning of the year 3,503 5,570 - - Provisions (*) 88 320 Payments and reclassifications (**) (278) (2,594) Realization of present value adjustment 54 207 - - Total 3,367 3,503 Current liability 1,092 1,107 Non-current liability 2,275 2,396 Total 3,367 3,503 (*) The change in the provision for the period ended March 31, 2026, mainly refers to: (i) based on the updated cost estimates for the action fronts in Alagoas, and (ii) the update of the present value adjustment due to the remeasurement of the discount rate and the revised estimate of disbursements over the years. The change in the provision in the fiscal year 2025 mainly refers to: (i) the signing of the Instrument of Agreement with the State of Alagoas; (ii) reversals resulting from updated cost estimates for the action fronts undertaken in Alagoas, and (iii) the update of the present value adjustment due to the remeasurement of the discount rate and revised estimates of disbursements over the years. In the fiscal year 2024, the variation in the provision was mainly caused by: (i) the update of cost estimates related to the closing of mining areas; b) Includes inflation/foreign exchange adjustment of R$6 (2025: R$(4) reported under Financial expenses. (**) Of this amount, R$130 (2025: R$1,348) refers to payments made and R$148 (2025: R$1,246) was reclassified to Other liabilities, which totals a balance of R$1,209 (2025: R$1,416) 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, including compensation that requires special relocation measures, such as hospitals, schools, and public facilities, whether they belong to private or public entities. This action has a provision of R$141 (2025: R$192) 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. Braskem S.A. Management notes to the parent company and consolidated quarterly information as of March 31, 2026 All amounts in thousands Reais, except as otherwise stated 48 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 is currently divided as follows: i) 18 cavities are expected to be filled with solid material with priority. To date, 6 cavities have been filled with sand, 4 cavities have reached the technical filling limit, 2 cavities are currently being evaluated to confirm whether the technical limit has been reached, 4 cavities are in the filling process, and 2 cavities are in the preparation and planning activities; ii) 6 cavities were naturally filled and, therefore, do not indicate, at this moment, the need for additional measures; 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$1,657 (2025: R$1,730) 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 in December 2023, as agreed in the Socio-Environmental Reparation Agreement, the specific Environmental Diagnosis and Environmental Plan to evaluate potential impacts caused by the collapse of said cavity, conducted by specialized firm, was completed. The action plan resulting from this study is still in progress. The document was acknowledged by the MPF in February 2026, at which time the ministerial body also approved the extension of the deadline for updating the Environmental Diagnosis, as stipulated in the Agreement, to 2027. 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 Braskem S.A. Management notes to the parent company and consolidated quarterly information as of March 31, 2026 All amounts in thousands Reais, except as otherwise stated 49 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, 3 are in progress and 2 are in the planning stage. Regarding the Social and Urban Action Plan ("PAS"), of the 44 planned actions, which may be changed in accordance with the authorities, 35 are under Braskem's responsibility (4 are completed and 7 are under implementation) and 9 are under of the responsibility of Municipality of Maceió, funded by the Company. The balance of the provision is R$779 (2025: R$793). 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$790 (2025: R$788). 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 compensate potential environmental impacts and damages, as provided for in the Socio-environmental Reparation Agreement, are in progress and eventually new measures may be necessary and will be consolidated as part of the measures for a Plan to Recover Degraded Areas (“PRAD”). The Company has been making progress in negotiations with private and 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. 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"). The Company has been monitoring the matters and their developments. In October 2025, the MPF filed charges based on the final report of the Federal Police from October 2024. The Company reiterates that it has always been at the disposal of authorities and will present its statement at the appropriate time in the legal proceedings. Additionally, 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 and/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 Braskem S.A. Management notes to the parent company and consolidated quarterly information as of March 31, 2026 All amounts in thousands Reais, except as otherwise stated 50 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. 23.1 Lawsuits in progress The contingent liabilities whose loss is assessed as possible by the Company’s Management, based on its evaluation and that of its external legal advisors, related to the geological event in Alagoas, are disclosed as follows: 2026 2025 Civil claims - Alagoas (*) 8,137 8,036 Environmental claims - Alagoas 98 96 Total (**) 8,235 8,132 (*) Amounts presented net of the portion of the provision for compensation and relocation of public and private facilities located on the Civil Defense Map (version 4) covered by lawsuits related to the topic. The total amount of provisions related to these claims is R$18. (**) Comprise the lawsuits with possible loss prognosis detailed below, and others of lesser value involved, including Public-Interest Civil Actions related to the relocation of certain public facilities located in the region.

Management notes to the parent company and consolidated quarterly information as of March 31, 2026 All amounts in thousands Reais, except as otherwise stated 51 In the context of this event, the main lawsuits filed against the Company are: Description of civil lawsuits Estimate 2026 2025 1) Public-Interest Civil Action - Reparation for Residents – Map Version 5 Plaintiffs: Federal Prosecution Office, Federal Public Defender’s Office and Alagoas State Prosecution Office On November 30, 2023, the Company was informed of the Public-Interest Civil Action filed by the plaintiffs against the Municipality of Maceió and Braskem, with a request for a injunctive relief based on evidence, against Braskem: (i) inclusion in the PCF of the new criticality area 00 (area defined by the Civil Defense of Maceió with recommendation of relocation) of Version 5 of the Civil Defense Map and the optional inclusion of all residents affected whose properties are located in the criticality area 01 (area defined by the Civil Defense of Maceió with recommendation of monitoring) of Version 5 of the Map, with inflation adjustment corresponding to the amounts adopted by the PCF; (ii) establishment, with the permission of the affected party of the criticality area 01, of a Program for Reparation of Damage to Properties resulting from the alleged depreciation of the property, as well as the alleged pain and suffering resulting from the inclusion of the property in the Map; (iii) engagement of independent and specialized firm to identify the alleged damages to properties if the affected party decides to remain in the area of criticality 01 of Version 5 of the Civil Defense Map; and (iv) engagement of independent and specialized technical advisory to provide support to the affected parties in the analysis of the scenarios and decision-making of their relocation or staying in the area. On the merits, they request confirmation of the preliminary injunctions. The preliminary injunctions granted at first instance on November 30, 2023 had their effects suspended on January 22, 2024, by decision of the Federal Regional Court of the 5th Region (“TRF5”), as a result of an interlocutory appeal filed by the Company. Said appeal was adjudicated on February 27, 2025 and was fully granted, resulting in the definitive dismissal of the effects of the preliminary injunction. In June 2025, the plaintiffs reiterated a request for relief based on evidentiary grounds, seeking the voluntary relocation of residents from a specific area of the Bom Parto neighborhood. On September 3, 2025, a decision was issued determining the inclusion of 13 properties previously interdicted by the Municipal Civil Defense in the Financial Compensation Program (“PCF”). However, on October 10, 2025, the TRF5 suspended the effects of such decision and, on March 31, 2026, upon ruling on the merits of the appeal, recognized the absence of any liability of the Company for the relocation and compensation of the aforementioned 13 properties located in Area AT-06B of the Bom Parto neighborhood. 1,279 1,245 Braskem S.A. Management notes to the parent company and consolidated quarterly information as of March 31, 2026 All amounts in thousands Reais, except as otherwise stated 52 2) Public-Interest Civil Action - Request for indemnification for additional collective pain and suffering Plaintiff: State Public Defender's Office of Alagoas 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. 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. On April 12, 2024, the preliminary injunction requests sought in the lawsuit were denied at first instance. Subsequently, on November 27, 2025, the Federal Regional Court of the 5th Region (“TRF5”), by unanimous decision, granted the appeal filed by the Company in July 2025, recognizing the lack of standing of the State Public Defender’s Office (“DPE”), as well as the validity of the previously executed settlement agreement and the res judicata effect, and ordered the dismissal of the lawsuit. On January 6, 2026, the DPE filed a motion seeking recognition of the nullity of the judgment session related to the aforementioned appeal. On March 17, 2026, the 3rd Federal Court rendered a decision dismissing the Public-Interest Civil Action, based on binding precedent established by the TRF5. The DPE filed motions for clarification against such decision, which are currently pending adjudication. 187 182 3) Public-Interest Civil Action - Border Area Entrepreneurs Plaintiff: State Public Defender's Office of Alagoas and Association of Entrepreneurs and Victims of Braskem In January 2026, the Company became aware of the Public-Interest Civil Action filed by the DPE and the Association of Entrepreneurs and Victims of Braskem, seeking to hold Braskem liable for damages allegedly suffered by entrepreneurs who conduct economic activities along the boundary of the Civil Defense Map, including Area 01. As a preliminary injunction, the plaintiffs seek the creation of an emergency support fund for entrepreneurs, with an initial contribution of R$ 0.4 by Braskem to subsidize loans for the benefit of the entrepreneurs. On the merits, they seek compensation for actual damages (including real estate devaluation, loss of improvements, and other property losses), loss of profits, loss of business goodwill, individual and collective moral damages, existential damages, and social damages. The Company submitted its defense on February 20, 2026. 2,043 2,000 Braskem S.A. Management notes to the parent company and consolidated quarterly information as of March 31, 2026 All amounts in thousands Reais, except as otherwise stated 53 4) 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. - - 5) Public-Interest Civil - Review of terms of the Flexal Agreement Plaintiff: Alagoas State Public Defender’s Office In March 2023, the Company became aware of the Public-Interest Civil Action filed by DPE against the Company, the Federal Government, the State of Alagoas and the Municipality of Maceió seeking, among other claims, the revision of terms of the Flexal Agreement, signed amongst Braskem, the MPF, the MPE, the DPU, and Municipality of Maceió, ratified on October 26, 2022, by the 3rd Federal Court of Alagoas. Through this lawsuit, the DPE seeks, among other claims, the inclusion of residents of the 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, the Alagoas State Government and the Federal Government filed appeals against this decision. On August 19, 2025, the appeals of both Braskem and the Federal Government were upheld on their merits, resulting in the reversal of the lower court’s ruling, the recognition of the validity of the agreement, and the annulment of the financial penalties previously imposed. The appeals of the State of Alagoas and the DPE were denied. Braskem, the State of Alagoas, and the Federal Government filed motions for clarification , which were pending adjudication at the time. On October 30, 2025, the TRF5 unanimously granted Braskem's interlocutory appeal and overturned the lower court's ruling that had ordered an anthropological expert examination. On March 24, 2026, the TRF5 denied the motions for clarification filed by Braskem, the State of Alagoas, and the Federal Government. As a result, the TRF5’s findings regarding the validity and enforceability of the Flexais Agreement, as well as the revocation of the order to conduct the anthropological technical expert examination, remain in full force and effect. 354 345 Braskem S.A. Management notes to the parent company and consolidated quarterly information as of March 31, 2026 All amounts in thousands Reais, except as otherwise stated 54 6) 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 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. On November 13, 2025, the TRF5 denied the appeal, and Braskem filed motions for clarification, which are pending adjudication. 2,023 1,970 7) 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. - - 8) Indemnity Claim Plaintiff: Companhia Brasileira de Trens Urbanos (“CBTU”) On February 2, 2021, the Company was notified of the filing of an action, formulating initially only a preliminary injunction for maintaining the Technical Terms of the Cooperation (operational) agreement signed previously by the parties. 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 memoranda 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. After the suspension period ended, on September 18, 2025, Braskem submitted its defense, and on October 15, 2025, CBTU filed a reply with its considerations. In the extrajudicial sphere, on August 26, 2025, CBTU and Braskem entered into a technical cooperation agreement aimed at enabling the road requalification of the railway section whose operations were suspended, reinforcing the understanding regarding the safe resumption of remodeling services in the mentioned section. 1,537 1,528 Braskem S.A. Management notes to the parent company and consolidated quarterly information as of March 31, 2026 All amounts in thousands Reais, except as otherwise stated 55 9) Indemnity Claim - 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. On July 5, 2023, a decision was rendered in favor of Braskem. It did not recognize the existence of the alleged loss of profits and alleged damage to the contractor’s image, only ordering the return of R$3 by Braskem to the plaintiff, plus inflation adjustment, to be deducted from the amounts already received by Humberto Lobo during the lawsuit. Appeals filed by the parties are pending judgment. On March 30, 2026, the Court of Justice of the State of Alagoas (“TJAL”) denied Braskem’s appeal and partially granted the Contractor’s appeal, and, by reforming the lower court decision, declared that the contractual termination occurred due to Braskem’s sole fault. The Company was ordered to pay damages in an amount equivalent to the market value of the property subject to the agreement, plus monetary restatement and default interest, as well as moral damages in the amount of BRL 0.3. On April 13, 2026, Braskem filed Motions for Clarification, which are pending judgment. 1 1 10) Indemnity Claim Plaintiff: State of Alagoas In March 2023, the Company became aware of the indemnity claim requesting compensation for alleged damages resulting, among others claims, from the loss of properties within the risk area defined by the Civil Defense of Maceió, alleged investments initiated by the State of Alagoas and that would have become void unusable due to the evacuation of the risk area and alleged loss of tax revenue, with a request that such damages to be determined by a court appraiser, with a preliminary request to block funds in Company's current account. An Instrument of Appeal was filed by Braskem. The preliminary injunction was granted. On October 10, 2023, the trial court handed down summary judgment ordering Braskem to reimburse the amounts invested, public equipment and losses in tax collection as required by the State of Alagoas. The indemnity amounts must be set in the award calculation phase. The Company filed an appeal against the decision. On April 7, 2025, the Court of Justice of Alagoas declared the absolute lack of jurisdiction of the State Court of Alagoas, ordering the transfer of the case to the Federal Court in Alagoas. In May 2025, a decision was issued suspending the transfer of the case to the Federal Court in a new appeal filed by the State of Alagoas. On November 10, 2025, Braskem and the State of Alagoas entered into the State Agreement, comprehensive and complete settlement agreement, fully releasing and extinguishing this compensation claim. On January 7, 2026, the Federal Court issued a decision approving the agreement, pending final judgment due to an appeal filed by the Federal Public Prosecutor's Office and the Public Defender's Office. On February 6, 2026, the MPF and the DPU filed an appeal seeking to overturn the decision with respect to matters involving the Portugal Ramalho Teaching Hospital, challenging the replacement of the obligation to perform with an obligation to pay, as well as the corresponding full and unrestricted discharge granted to Braskem. Braskem, in turn, submitted its counterarguments to the appeal. The appeal is pending judgment. - - 11) Other civil actions - Indemnifications related to the impacts of subsidence and relocation of areas affected The Company is defendant in several other actions filed by individuals in Brazil and abroad, seeking the payment of indemnifications directly or indirectly related to the geological event in Maceió. 713 765 Total civil lawsuits 8,137 8,036 Braskem S.A. Management notes to the parent company and consolidated quarterly information as of March 31, 2026 All amounts in thousands Reais, except as otherwise stated 56 Description of environmental lawsuits Estimate 2026 2025 1) Notice of violation Plaintiff: Environment Institute of Alagoas State (“IMA”) On December 4, 2023, the IMA issued a fine to the Company due to the alleged environmental degradation resulting from the soil displacement in the region where the mining front is closed in the municipality of Maceió. Considering that in 2019 Braskem had already been fined for the same event and legal grounds, a defense to the notice of violation was filed for bis in idem. The original notice of violation of 2019 was closed with the signature of the Consent Decree (TAC) on December 23, 2023. On December 9, 2025, a final administrative decision was issued upholding the application of the fine. On February 6, 2026, the Company filed a judicial action seeking the suspension of its enforceability, and a preliminary injunction was granted on February 9, 2026. On April 15, 2026, a judgment dismissing the claim was rendered, against which the Company filed Motions for Clarification on April 16, 2026, resulting in the reinstatement of the effects of the injunction suspending the notice of violation. The case is currently pending before the judicial courts. 90 88 2) Sundry environmental lawsuits 8 8 Total environmental lawsuits 98 96 Total lawsuits with probability of possible loss 8,235 8,132 Braskem S.A.

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. In the periods ended March 31, 2026 and March 31, 2025, no shares were delivered. Braskem S.A.
