The Shareholders’ Meeting will be held exclusively in a digital format, considering that such format, in the judgment of the Management, reduces the costs of participation for shareholders, facilitating and contributing to greater attendance by the Company’s shareholder base at the Meeting and, thus, potentially increasing the representativeness of the resolutions to be taken.

The accounting practices adopted in Brazil comprise those included in Brazilian corporate law and the pronouncements, guidelines and technical interpretations issued by the Accounting Pronouncements Committee ("CPC") and approved by the Federal Accounting Council ("CFC") and the Brazilian Securities and Exchange Commission ("CVM"). The consolidated financial statements (“Financial Statements”)for the fiscal year ended December 31, 2025 have been prepared and are presented in accordance with the accounting practices adopted in Brazil and with the International Financial Reporting Standards ("IFRS") issued by the International Accounting Standards Board ("IASB"), currently referred to by the IFRS Foundation as "IFRS accounting standards".

The terms "HA" and "VA" in the columns of certain tables in item 2 generally mean "Horizontal Analysis" and "Vertical Analysis", respectively. 2.1 – Comments by the directors financial and equity conditions 2.1.a – General financial and asset conditions On December 31, 2025, the Company recorded a loss for the year attributable to shareholders1 of R$9,880 million, representing a reduction compared to 2024 mainly due to (i) the reduction of R$4,441 million in gross income in the period, from R$5,997 million in 2024 to R$1,556 million in 2025; and (ii) the write-off of deferred tax assets with a net impact on the result of R$7,593 million, resulting from factors that indicate potential unavailability of future taxable profits, mainly as a result of current uncertainties in the sector, according to CPC 32. Such effects were partially offset by the increase of R$14,995 million in net income from hedges and exchange rate variations, which reached R$3,474 million in 2025, compared to the negative result of R$11,520 million in 2024. Regarding the Company's equity conditions, as of December 31, 2025, the total shareholders' equity attributable to the Company's shareholders¹ was negative R$16,147 million. In the fiscal year ended December 31, 2025, the Company, excluding Braskem Idesa and its subsidiaries, presented a corporate financial leverage of 14.38x in Brazilian reais and 14.74x in US dollars, the calculation of which is shown in item 2.5 of this form. The Company's liquidity indicators, in the fiscal years ended December 31, 2025, and 2024, are presented in the following table: Liquidity Indicator 2025 2024 Current Liquidity (1) 0.76x 1.31x General Liquidity (2) 0.83x 0.96x Note 1: Current Liquidity = Current Assets / Current Liabilities Note 2: General Liquidity = (Current Assets + Non-Current Assets) / (Current Liabilities + Non-Current Liabilities) 2.1.b – Capital structure The Company's capital structure for the fiscal years ended December 31, 2025 and 2024 is presented in the following table: Capital structure in R$ million 2025 2024 Third-party capital 98,381 105,853 Equity (16,502) (4,278) Total capital (third party + own) 81,879 101,575 The Company uses the capital market as its main source of third-party capital resources, also obtaining funds from commercial banks, development banks and international credit agencies. With respect to Braskem Idesa's capital structure, on August 28, 2025, the Company communicated to the market in general that the Company and Idesa, in response, especially, to market conditions, were discussing a wide range of options to address the challenges of Braskem Idesa's capital structure. On September 8, 2025, the Company informed 1 It does not consider the participation of non-controlling shareholders in subsidiaries. the market in general that Braskem Idesa, in order to review its current capital structure and liquidity conditions, has engaged experienced legal and financial advisors to support Braskem Idesa in evaluating a wide range of economic and financial options. On November 19, 2025, the Company informed the general market that Braskem Idesa announced the non-payment of interest scheduled for November 18 on its senior secured notes due in 2029, with an outstanding principal amount of US$900 million. As a result, Braskem Idesa fully reclassified the principal amounts of its debts from non-current to current liabilities, totaling R$12,083 million (US$2,196 million), of which R$4,954 million (US$900 million) related to the 2029 bond, R$6,606 million (US$1,201 million) related to the 2032 bond and R$523 million (US$95 million) related to the Term Loan. Due to the non-compliance with contractual clauses of the financing that supported the hedge relationships, Braskem Idesa proceeded with the discontinuation of hedge accounting. On January 12, 2026, the Company informed the market in general that Braskem Idesa shared certain non-public information with holders and managers of its Senior Secured Notes due in 2029 and 2032, in the context of discussions on a reorganization of its capital structure, clarifying that there was an exchange of proposals between the parties, without any agreement reached at that time, and that the information disclosed does not constitute guidance practice. On February 20, 2026, the Company informed the general market that Braskem Idesa announced the non-payment of interest scheduled for February 20, 2026 on its senior secured notes due 2032. 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 shareholding control of Braskem Idesa. As mentioned in Note 1 (The Company's economic and financial condition and the maintenance of the going concern assumption) to the Consolidated and Individual Financial Statements for the year ended December 31, 2025, in September 2025 In September 2025, the Company has engaged financial and legal advisors (Lazard Inc., Cleary Gottlieb Steen & Hamilton LLP, and E. Munhoz Advogados) to assist in preparing a diagnosis of the economic-financial alternatives to reorganize its capital structure. Among the initiatives currently under development, the reorganization of the capital structure stands out, which depends on variables outside the Company’s exclusive control. The evaluation process of this alternative began in September 2025, when the Company informed the market of the engagement of specialized financial and legal advisors to support a comprehensive assessment of the available economic and financial options, with a focus on strengthening the liquidity of the capital structure. 2.1.c – Payment capacity in relation to the financial commitments undertaken In the year ended 2025, the Company sought to sustain its level of liquidity, using, among others measures, on the drawdown of the international revolving credit line, thus ensuring coverage of its operational and financial obligations. In the fiscal year ended December 31, 2025, the Company raised funds from third parties in the total amount of R$5,453 million, without considering the fundraising from third parties made by the subsidiary Braskem Idesa and its subsidiaries. Of this amount, R$5,350 million (US$1,000 million) represents the drawdown of the international revolving credit facility (RCF), with payment scheduled for December 2026. Braskem Idesa and its subsidiaries raised funds from third parties in the amount of R$972 million in the fiscal year ended December 31, 2025. The Company's ability to pay may be affected by several risk factors including, but not limited to, the imbalance between global supply and demand for chemical products, reducing chemical and petrochemical spreads in the international market, impacting the profitability and credit conditions of the industry and the Company, lower feedstock competitiveness and increased imports of resins in the regions where the Company operates, unfavorable outcomes of ongoing lawsuits, limitations on insurance coverage in case of damages, among other important factors. The Company's main cash needs include: (i) financing and maintenance of working capital; (ii) payment of debt service; (iii) investments in operations, including reliability and modernization of its main productive assets; (iv) payment of taxes; and (v) strategic investments. To meet such cash needs, the Company has relied on cash generated by operating activities and third-party capital, including working capital management. At the end of the fiscal year ended December 31, 2025, and due to the credit deterioration of the global chemical and petrochemical industry, the Company presented the following reductions in risk assessments on a global scale by the rating agencies Standard & Poor's and Fitch Ratings: Rating Agencies On 31 December 2025 2024 Global scale rating Fitch Ratings CC BB+ (Negative Outlook) Standard & Poor’s CCC- (Negative Outlook) BB+ (Negative Outlook) National Scale Rating Fitch Ratings CC (bra) AAA (bra) (Outlook stable) Standard & Poor’s brCCC- (Negative Outlook) brAAA (Negative Outlook) 2.1.d – Sources of financing for working capital and investments in non-current assets used As stated in the previous item, the Company used funds originated in its operations and funds raised from third parties, mainly for financing and maintaining working capital and investments in non-current assets. Regarding working capital, the Company actively manages its receivables, payment and inventory levels. As part of this management, the Company carries out financial operations to anticipate its accounts receivable from customers with financial institutions and funds intended for the acquisition of receivables. On December 31, 2025, the amounts of assigned accounts receivable securities maturing after December 31, 2025, corresponded to R$3,211 million on a consolidated basis, while in 2024 it was R$4,981 million. The amounts of interest expenses related to the assignments of the securities mentioned above correspond to R$90 million in 2025, while in 2024 it was R$73 million, recorded under the heading "financial expenses". The Company provides letters of credit, issued by financial institutions, to certain suppliers and has payment agreements with financial institutions. At the end of the 2025 fiscal year, the Company had in letters of credit related to purchases of feedstock maturing within 360 days the amount of R$7,758 million, while at the end of the 2024 fiscal year the balance was R$9,170 million. The Company has payment agreements with financial institutions and forfaiting contracts that allow certain suppliers to opt for the assignment of their receivables from the Company, upon acceptance by the financial institutions for acquiring (or not) such receivables, without interference from the Company. The balances classified as forfaiting represent amounts already anticipated to the Company's suppliers, which, in 2025, suffered a reduction in the available limits of payment agreements with financial institutions. The maturity of the receivables that are part of the forfaiting program is equivalent to the maturity of the accounts payables of Braskem's other suppliers in Brazil, and the maturity range of such bonds is between 30 and 180 days. In addition, on October 3, 2025, the Company drawdown its international revolving credit line, contracted abroad, in the amount of R$5,350 million (US$1,000 million), as disclosed in the Material Fact, maturing in December 2026. Also in 2025, considering the REIQ Investimentos, which consists of the presumed credit of 1.5% of PIS/COFINS linked to investments in the Brazilian chemical industry, the Company recorded R$858 million (US$157 million) in net tax credits. This amount is mainly related to investments for the implementation of the Transforma Rio project, in technology for efficiency in the resin chain, in the adaptation of the process for the industrial production of new copolymer grades, and in other projects already approved under REIQ Investimentos, calculated in accordance with current legislation. 2.1.e – Sources of financing for working capital and for investments in non-current assets that it intends to use to cover liquidity shortfalls The Company seeks to address any liquidity deficiencies through the combination of: (i) funds originating from its operations; (ii) funds raised through financing, including new funding and refinancing of existing debts; and (iii) resources arising from the reduction of the operating cycle and consequent reduction in the need for working capital financing. Due to the prolonged global downturn in the petrochemical sector and the economic and financial adversities faced by Braskem S.A., shareholders and the market in general were informed on September 26, 2025, of the engagement of financial and legal advisors to assist the Company in the preparation of a diagnosis of economic and financial alternatives to optimize its capital structure, compatible with the operational and financial challenges of Braskem S.A. 2.1.f – Levels of indebtedness and the characteristics of such debts The Company's debt profile can be summarized in the following table: Consolidated Indebtedness In R$ million December 31, 2025 Short-Term Debts 8,268 Long-Term Debts 43,553 Total 51,821 By currency Debts in Brazilian reais 6% Debts subject to the exchange rate variation of the dollar 94% Debts subject to exchange rate variations of other currencies 0% By type of warranty Unsecured Debts 98% Debts covered by collateral 2% Debts covered by other types of collateral 0% The amortization schedule for Braskem's consolidated debt is summarized in the table below: Consolidated Indebtedness in R$ million 2026 2027 2028 2029 2030 2031 2032 2033 2034 onwards TOTAL National Currency 610 378 746 1,960 216 172 113 0 0 4,195 Foreign Currency (1) 8,297 1,392 8,585 5,612 8,285 4,680 6,517 5,469 13,095 47,626 Total 8,907 1,770 9,331 7,572 8,501 4,852 6,630 5,469 13,095 51,821 Note 2: The table reflects the original schedule for the payment of Braskem Idesa's financing.

The proceeds from this new financing were used for the early settlement of the financing with an original maturity of October 2026. Note 2: In October 2025, Braskem Idesa increased the amount of Term Loan that had been contracted in May 2025, from R$ 523 million (US$95 million) to R$990 million (US$180 million). Disbursements resulting from the expansion of this credit line are due in December 2026. In October 2025, Braskem Idesa made withdrawals totaling R$188 million (US$34 million) from a credit line contracted with Banco Inbursa, whose total available limit is R$468 million (US$85 million). This credit line matures in December 2026.

Note 2: The table reflects the original schedule for the payment of Braskem Idesa's financing. In November 2025, Braskem Idesa did not make the interest payments scheduled for the month and as a result of this fact, Braskem Idesa reclassified the bond balance to current liabilities. With the exception of certain reserve accounts linked to the fulfillment of contractual obligations, Braskem's financing and debentures comprise unsecured obligations. From a contractual point of view, with the exception of the Bond issued in July 2020, there is no subordination between the debts, so that the payment of each of them must observe the maturity date established in each contractual instrument, regardless of the payment of the other debts. 2.1.f (iv) – Restrictions imposed on the Company, in particular, in relation to indebtedness limits and contracting of new debts, distribution of dividends, sale of assets, issuance of new securities and sale of corporate control The debts in which the Company, excluding Braskem Idesa and its subsidiaries, appear as issuer or guarantor do not have restrictions in relation to limits for certain indicators related to the capacity to borrow and pay interest. However, some of these financing agreements contain other obligations that restrict, among others, the ability of the Company and most of its subsidiaries to grant guarantees, merge, transfer or otherwise lien of all or substantially all of their assets. The debts in which Braskem Idesa and its subsidiaries appear as issuer or guarantor have restrictions on contracting indebtedness, payment of dividends, sale of assets and encumbrance of assets, according to the respective financing and bond agreements. The restrictions described above did not lead to the acceleration of any of the financing agreements entered into by the Company at the end of the fiscal year ended December 31, 2025. In November 2025, Braskem Idesa defaulted on interest due on the bond due in 2029. In December 2025, the balance of this interest, recorded in current liabilities, totaled R$230 million (US$42 million). As a result of this non-payment, the total interest and principal balance of the bond may be accelerated if the bondholders, subject to the applicable contractual quorums, vote to do so. As the decision to accelerate the debt is not under the control of Braskem Idesa, which does not have the ability to postpone such payments for at least 12 months after the balance sheet date, the balances of this obligation were classified in current liabilities, as well as other debts that provide for cross default clauses in its contracts. Thus, Braskem Idesa fully reclassified the principal amounts of its debts from non-current to current liabilities, totaling R$12,083 million (US$2,196 million), of which R$4,954 million (US$900 million) related to the 2029 bond, R$6,606 million (US$1,201 million) related to the 2032 bond and R$523 million (US$95 million) related to the Term Loan. Due to the non-compliance with contractual clauses of the financing that supported the hedge relationships, Braskem Idesa discontinued hedge accounting. 2.1.g – Limits of contracted financing and percentages already used On December 31, 2025, the credit limit contracted by the Company, excluding the limits contracted by Braskem Idesa and its subsidiaries, was used through the R$5.350 million (US$1,000 million) stand-by credit facility, due in December 2026, which was drawdown on October 3, 2025. In October 2025, Braskem Idesa increased the amount of the Term Loan that had been contracted in May 2025, from R$523 million (US$95 million) to R$990 million (US$180 million). The disbursements resulting from the expansion of the aforementioned credit line are due on December 31, 2026. Throughout the last quarter of 2025, Braskem Idesa made withdrawals from the Term Loan that totaled R$188 million (US$34 million). On December 31, 2025, Braskem Idesa used about 72% of the total credit limit contracted through the Term Loan, considering the initial agreement and subsequent increase. 2.1.h – Material changes in each item of the financial statements Income Statement (R$ million) Dec/25 (A) AV (%) Dec/24 (B) AV (%) AH (A)/(B) AH (A)-(B) Net sales and service revenue 70,717 100% 77,411 100% (9%) (6,694) Cost of goods sold (69,161) (98%) (71,414) (92%) (3%) 2,253 Gross Profit 1,556 2% 5,997 8% (74%) (4,441) Selling and Distribution Expenses (2,067) (3%) (1,991) (3%) 4% (76) (Reduction) reversion to recoverable amount of accounts receivable and other accounts receivable from customers (125) (0%) 108 0% (216%) (233) General and administrative (2,615) (4%) (2,639) (3%) (1%) 24 Research and development (460) (1%) (463) (1%) (1%) 3 Income from equity interests 9 0% (21) (0%) (143%) 30 Other net income (expenses) 1,895 3% (2,070) (3%) (192%) 3,965 Earnings before net financial expenses and taxes (1,807) (3%) (1,079) (1%) 68% (728) Net financial result (1,038) (1%) (16,654) (22%) (94%) 15,616 Financial expenses (6,802) (10%) (6,853) (9%) (1%) 51 Financial revenues 2,290 3% 1,719 2% 33% 571 Income from derivatives and exchange rate variations, net 3,474 5% (11,520) (15%) (130%) 14,994 Profit (loss) before income tax and social contribution (2,845) (4%) (17,733) (23%) (84%) 14,888 Income tax and social contribution - current and deferred (8,116) (11%) 5,681 7% (243%) (13,797) Net income (loss) for the period (10,961) (15%) (12,052) (16%) (19%) 1,091 Attributable to: Shareholders of Companhia (9,880) (14%) (11,320) (15%) (13%) 1,440 Participation of non-controlling shareholders in subsidiaries (1,081) (2%) (732) (1%) 48% (349) The main variations in the operating results of the last fiscal year can be explained as follows: NET SALES AND SERVICE REVENUE Net revenue from sales and services was lower by R$6,694 million, or 9%, to R$70,717 million in 2025, from R$77,411 million in 2024, mainly explained by the reduction of (i) R$3,070 million in net revenue from the Brazil segment, due to the reduction in the average international reference price of resins and main chemicals, with a negative impact of R$973 million; and the reduction in the volume of sales of resins and main chemicals in the Brazilian market and exports, with a negative impact of R$2,235 million; (ii) R$3,044 million in net revenue from the United States and Europe segment; and (iii) R$1,045 million in net revenue from the Mexico segment, due to the reduction in the average international reference price of PE, with a negative impact of R$423 million; and the reduction in the volume of sales of PE in the year, with a negative impact of R$622 million. Such effects were partially offset by the positive impact on the Brazil segment of the presumed PIS/COFINS credits under the REIQ Investments in the net amount of R$583 million (US$106 million). COST OF GOODS SOLD AND GROSS PROFIT In the period, the cost of goods sold decreased by R$2,253 million, or 3%, to R$69,161 million in 2025, from R$71,414 million in 2024, mainly explained by (i) a reduction of R$1,949 million in the cost of goods sold in the Brazil segment; and (ii) a reduction of R$1,747 million in the cost of goods sold in the United States and Europe segment. These effects were partially offset by an increase of R$1,699 million in the cost of goods sold in Mexico, mainly by the recording of impairment loss of approximately R$1,468 million, after the identification that Braskem Idesa's recoverable amounts of assets were lower than the respective book values. During 2025, COGS was positively impacted by PIS/COFINS credits on the purchase of feedstock (REIQ) by approximately R$273 million (US$46 million) and by Reintegra credits by R$8.4 million (US$1.5 million). Gross profit decreased by R$4,441 million, to R$1,556 million in 2025 from R$5,997 million in 2024. Gross margin (gross profit as a percentage of net revenue) reduced to 2.2% in 2025 from 7.7% in 2024. SELLING AND DISTRIBUTION EXPENSES Sales and distribution expenses increased by R$76 million, or 4%, to R$2,067 million in 2025 from R$1,991 million in 2024, mainly due to (i) the increase in logistics expenses and expenses with storage and tanking services, due to the scheduled shutdown of Braskem Idesa's petrochemical plant; and (ii) the depreciation of the average real against the average dollar of 4% in the period. REVERSAL OF (LOSS FOR) IMPAIRMENT OF TRADE ACCOUNTS RECEIVABLE AND OTHERS FROM CLIENTS Losses with reduction in the recoverable amount of accounts receivable and other customer receivables totaled R$125 million in 2025, from a reversal of R$108 million in 2024, mainly explained by the increase in provisions for losses in accounts receivable during 2025. GENERAL AND ADMINISTRATIVE EXPENSES General and administrative expenses decreased by R$24 million, or 1%, to R$2,615 million in 2025 from R$2,639 million in 2024, mainly from the lower administrative expenses associated with Cetrel S.A., which was sold in September 2024. These effects were partially offset by the depreciation of the average real against the average dollar of 4% in the period. The indicator of general and administrative expenses as a percentage of net revenue was 3.7% in 2025, compared to 3.4% in the corresponding period of 2024. RESEARCH AND DEVELOPMENT EXPENSES Research and development expenses decreased by R$3 million, or 1%, compared to 2024, totaling R$460 million in 2025, from R$463 million in 2024, mainly due to the decision to discontinue new investments in Oxygea. This decision is in line with the Company's strategic direction of prioritizing its assets and investments, both operational and strategic, in the search for optimizing capital allocation and cash generation. RESULT OF EQUITY INTERESTS Equity results increased by R$30 million, to a revenue of R$9 million in 2025, from an expense of R$21 million in 2024, due to the higher net income recorded by the investees Borealis Brasil S.A. and Plaind Investimentos S.A. (Holding company created and maintained to manage the control of Cetrel and DAC). This effect was partially offset by the higher loss of Bioglycols LLC. OTHER RECIPES Other revenues increased by R$2,236 million, to R$3,213 million in 2025, from R$978 million in 2024, mainly explained by (i) the recognition of a tax credit of approximately R$1,670 million related to the deduction of Cide-Combustíveis paid from PIS/COFINS due on the sale of gasoline since 2004; (ii) the recognition of PIS and COFINS credits related to the REIQ in the purchase of inputs in the amount of R$465 million, calculated in accordance with current legislation, which are subject to offsetting with federal taxes, subject to the legal terms and conditions; (iii) for the recognition of remaining PIS and COFINS credits from previous years related to the exclusion of ICMS from the calculation basis of these contributions in the amount of R$293 million; and (iv) the reversal of the withholding tax provision of Braskem Netherlands B.V related to the concepts of international tax reform (Pillar Two) in the amount of R$161 million. OTHER EXPENSES The reduction in other expenses from R$1,730 million, or 57%, to R$1,318 million in 2025, from R$3,048 million in 2024, is mainly explained by (i) expenses related to the shutdown of the chlor-alkali plant in Alagoas of R$253 million; (ii) for the provision related to the geological event in Alagoas of approximately R$324 million; (iii) for the discount related to the sale of credit rights, of approximately R$208 million; and (iv) the annual review of the net environmental provisions of the industrial units located in Brazil of approximately R$131 million. EARNINGS BEFORE NET FINANCIAL EXPENSES AND TAXES Earnings before net financial expenses and taxes decreased by R$728 million, from -R$1,079 million in 2024 to -R$1,807 million in 2025. The result is mainly explained by the lower result of (i) the United States and Europe segments, which decreased R$1,260 million to a loss of R$718 million in 2025, compared to a profit of R$542 million in 2024, due to the reduction of international propylene price references; and (ii) the Mexico segment, which decreased R$2,521 million to a loss of R$2,390 million in 2025, from a profit of R$130 million in 2024, due to the 16% reduction in PE sales volume in the year added to a 12% reduction in the international PE price reference of the United States in the period. These effects were partially offset by the result of the Brazil/South America segment, which increased by R$2,514 million, from R$119 million to R$2,633 million, mainly due to (i) the 7% increase in resin exports; and (ii) the positive impact of the recognition of presumed PIS/COFINS credits within the scope of REIQ Investments. FINANCIAL RESULT Financial Expenses The reduction in Financial Expenses by R$51 million, or 1%, to R$6,802 million in 2025 from R$6,853 million in 2024 is mainly explained by (i) lower interest expenses related to Braskem Idesa's Shareholder Loan, after its capitalization in 2024; and (ii) the appreciation of the Brazilian real at the end of the period against the U.S. dollar, of about 7.4%. The effect was partially offset by the increase in financial expenses related to tax regularization for the settlement and installment of ICMS debts. Financial Revenue Financial income increased by R$571 million, or 33%, to R$2,290 million in 2025, compared to R$1,719 million in 2024, mainly due to: (i) monetary adjustment related to the recovery of PIS/COFINS tax credits, associated with the deduction of CIDE-Fuels on gasoline sales, amounting to approximately R$890 million; and (ii) interest income of approximately R$132 million, related to the recovery of presumed PIS/COFINS credits under the Industrial REIQ program, resulting from the abrupt suspension of the benefit in July 2022, in violation of the Brazilian National Tax Code. Results from derivatives and exchange rate variations, net Net income from derivatives and exchange rate variations increased by R$14,994 million, to revenues of R$3,474 million in 2025 compared to expenses of R$11,520 million in 2024, mainly due to the effects of (i) appreciation of about 11.1% of the final real of the period against the dollar on the annual average of net exposure to the dollar in the amount of US$4,102 million; and (ii) appreciation of around 11.4% of the Mexican peso at the end of the period against the dollar over the average annual exposure to the dollar of Braskem Idesa in the amount of US$1,860 million. INCOME TAX AND SOCIAL CONTRIBUTION – CURRENT AND DEFERRED Income tax and social contribution was negative by R$8,116 million in 2025. The reduction in relation to the positive amount of R$5,681 million in 2024 is mainly explained by (i) the revaluation of the recoverability of the deferred tax assets of the Company and its subsidiaries with a negative effect of R$7,593 million; and (ii) the reduction of R$5,049 million in deferred assets calculated in the year , mainly due to the lower loss before income tax and social contribution impacted by the increase of R$14,994 million in income from derivatives and exchange rate variations. NET INCOME (LOSS) FOR THE YEAR The Company recorded a loss of R$10,961 million in 2025, lower when compared to the loss of R$12,052 million in 2024, mainly due to (i) the reduction of R$4,441 million in gross profit in the period, from R$5,997 million in 2024 to R$1,556 million in 2025; and (ii) the write-off of deferred tax assets with a net impact on the result of R$8,759 million, resulting from factors that indicate potential unavailability of future taxable profits, mainly as a result of current uncertainties in the sector, according to CPC 32. Such effects were partially offset by the increase of R$14,994 million in net income from derivatives and exchange rate variations, which reached R$3,474 million in 2025, compared to the negative result of R$11,520 million in 2024. CASH FLOW Cash Flow Statement (R$ million) CONSOLIDATED Dec/25 (A) Dec/24 (B) AH (%) (A)/(B) AH (Absolute) (A)-(B) Net cash generated (used) by operating activities (4,200) 2,435 N/A (6,635) Utilization of cash in investing activities (2,947) (3,485) (15%) 538 Cash generation in financing 3,175 469 N/A 2,706 Exchange rate variation of the cash of subsidiaries abroad (513) 1,380 (137%) (1,893) Increase in cash and cash equivalents (4,485) 799 N/A (5,284) Cash flows from Operating Activities The variation between the net cash used in operating activities of R$4,200 million in 2025 and the net cash generated by operating activities of R$2,435 million in 2024 is mainly explained: (a) the reduction of R$2,711 million in Financial Investments, from R$3,325 million in 2024 to R$614 million in 2025; (b) the negative variation in working capital in the period, mainly due to (i) the negative variation of R$2,523 million in suppliers, from a positive result of R$384 million in 2024 to a negative result of R$2,343 million in 2025; and (ii) the negative variation of R$240 million in accounts receivable. Such reductions are mainly explained by the reduction in the availability of certain payment agreements with financial institutions and suppliers. These effects were partially offset by the optimization of inventory levels and tax monetization during the year, initiatives included in the Company's Resilience Program; (c) for the variation of R$542 million related to the increase in payments and reclassifications related to the Geological Event of Alagoas, from R$2,052 million in 2024, to R$2,594 million in 2025. Of the amount at the end of 2025, R$1,348 million refer to payments made and R$1,246 million refer to reclassifications to the Other obligations group, which totaled a balance of R$1,416 million referring to accounts payable of the Geological Event in Alagoas. Cash flows used in investing activities The use of cash in investing activities was R$2,947 million in 2025, a reduction of R$538 million compared to the net cash used in investing activities in 2024, of R$3,485 million, mainly due to the lower amount of additions to property, plant and equipment and intangibles, due to the optimization and prioritization of investments during the year. Cash generation in financing In 2025, the use of cash in financing was R$3,175 million, R$2,706 million higher than the amount presented in 2024, mainly due to the following operations: • R$5.350 million (US$1,000 million) related to the withdrawal of the "stand-by" credit facility; • R$550 million (US$95 million) related to Braskem Idesa's "Term Loan" financing agreement with Banco Inbursa; and • R$188 million (US$34 million) in a credit line contracted with Banco Inbursa, which total available limit is R$468 million (US$85 million). During 2025, the Company paid R$606 million (US$100 million) related to the payment of export credit lines, in the amount of R$5,228 million less than that disbursed in 2024, mainly due to (i) the partial redemption of debt securities maturing in 2081; and (ii) the payment of credit lines for exports. 2.2 – Officers’ comments on operating and financial results: 2.2.a – Results of the Company's operations (i) description of any important components of the recipe The information in this item is set forth in 2.2(b) below. (ii) factors that materially affected the results of operations Growth of the Brazil’s GDP and Domestic Demand for the Company's goods The Company's sales volume has an important correlation with the global economic situation and in the countries where it operates. Profit and loss of operations and financial condition have been and will continue to be affected by changes in global GDP and changes in global GDP and changes in GDP in Brazil, the United States, Europe and Mexico According to the IMF, the growth of the global economy should remain stable, amid the progress of global disinflation. World GDP expanded by 3.3% in 2023, 3.3% in 2024, 3.3% in 2025, and is expected to grow by 3.3% in 2026 and 3.2% in 2027. In the fiscal year ended December 31, 2025, sales in the Brazilian market and exports from the Brazil segment represented 71% of the consolidated net revenue of all the Company's segments. The following table shows the growth rates of the Brazilian GDP and other relevant macroeconomic indicators in the periods presented: Fiscal Year Ended December 31, 2025 GDP Growth/Reduction (1) 2.3% Inflation (IGP-M) (2) (1.1%) Inflation (IPCA) (3) 3.8% CDI Rate (4) 14.9% Appreciation (devaluation) of the real vs. dollar (11%) End-of-period exchange rate ($1.00) R$5.5024 Sources: Note 1: Brazilian GDP measured according to the IBGE Automatic Recovery System SIDRA. Note 2: Inflation measured by the General Market Price Index (IGP-M) of the Getúlio Vargas Foundation. Note 3: Inflation measured by the IBGE's Extended National Consumer Price Index (IPCA). Note 4: The CDI rate is the average of the overnight interbank rates in Brazil (on the last date of the respective period). The Company's management believes that the growth rate of the Brazilian GDP, which has been fluctuating, should maintain this behavior in the future. Management also believes that economic growth in Brazil could positively impact net sales and service revenue and operating results in the Brazil segment. Effects of exchange rate fluctuations between the real and the dollar The Company's operating results and financial condition have been and will continue to be affected by the devaluation or appreciation of the Brazilian real against the U.S. dollar, since: (i) a substantial portion of the Company's net revenue is denominated or linked to the U.S. dollar; (ii) the costs of feedstock and certain inputs necessary in the production processes are in dollars or are linked to this currency; (iii) operating expenses and investments of other natures are denominated in dollars or are linked to this currency; and (iv) significant amounts of dollar-denominated liabilities that require payment of principal and interest in that currency. Practically all the Company's sales are of petrochemical products whose prices in the international market are expressed in dollars. In general, management seeks to set prices considering: (i) the price of chemicals and petrochemicals in international markets; and (ii) in Brazil, the variations in the real/dollar exchange rate. Thus, although a significant portion of net sales and service revenues are denominated in Brazilian reais, the Company's products are sold at prices based on the international market, quoted in dollars. Fluctuations in the Brazilian reais affect the cost of naphtha, ethane, propane, propylene and other feedstock. Feedstock contracts with Petrobras are linked to the dollar. The pricing formula includes a factor that adjusts the price in Brazilian reais. The devaluation of the Brazilian real against the U.S. dollar increases the production costs of its products and the Company normally seeks to increase the prices of its products in Brazilian reais (to the extent possible, considering the market conditions prevailing in Brazil), which may result in a reduction in the sales volumes of its products in the Brazilian market. To the extent that price increases are not sufficient to cover increases in the cost of feedstock, the Company's gross margin decreases. In periods of high volatility of the dollar/real exchange rate, there is usually a lag between the moment when the dollar appreciates or depreciates and the moment when the Company sets prices to its customers. These price mismatches diminish when the real/dollar exchange rate is less volatile. The Company may carry out transactions with financial derivatives to mitigate the exchange rate risk associated with the exposure of costs in Brazilian reais. These operations may include call and put options or other derivative operations. For example, the Company may apply a protection strategy called collar, which consists of the purchase of a put option associated with the simultaneous sale of a call option, both with the same expiration. In this case, if the Brazilian real depreciates and the exchange rate on the exercise date of the option exceeds the exercise price of the call option, the Company may suffer significant financial losses. However, since these strategies will be implemented only for non-speculative purposes (in accordance with the Company's financial policy), the potential losses on derivative transactions should be offset by more competitive fixed costs in Brazilian reais. The Company's corporate debt in U.S. dollars represented 91.9% of its indebtedness as of December 31, 2025, excluding debt related to Braskem Idesa and its subsidiaries. Considering the inclusion of Braskem Idesa and its subsidiaries, the Company's consolidated indebtedness in U.S. dollars represented 93.7% of its indebtedness as of December 31, 2025. As a consequence, when the real depreciates against the dollar: (i) interest costs on debt expressed in dollars increase when converted to Brazilian reais, negatively affecting the net income from operations in Brazilian reais; (ii) the amount of debt in dollars increases when expressed in Brazilian reais, increasing total obligations and debt service in Brazilian reais; and (iii) financial expenses tend to increase as a result of the foreign exchange losses that the Company records, mitigated by the Company's decision on May 1, 2013, October 10, 2017, February 1, 2019, May 2, 2019, November 1, 2019, January 2, 2020, March 1, 2021, 1 September 2022, 1 October 2023, 1 November 2024, 30 April 2025 and 1 July 2025, to designate part of the US dollar-denominated liabilities as a hedge for future exports. Export sales and sales in the United States and Europe segment, which allow the Company to have receivables in foreign currencies, tend to provide a hedge against a portion of the Company's U.S. dollar debt service obligations. In addition, because the Company's sales in Brazil consider the price of chemical and petrochemical products in international markets and variations in the real/dollar exchange rate, the Company expands the risk mitigation to liabilities denominated in U.S. dollars. The real/US dollar exchange rate has varied significantly over time. On December 31, 2025, the real/US dollar exchange rate reported by the Central Bank was R$5.5024 to US$1.00. Effects of Brazilian Inflation Brazilian inflation affects the Company's financial performance to the extent that it increases operating expenses expressed in Brazilian reais (and not linked to the dollar). A significant portion of its cost of goods sold, however, is pegged to the dollar, not being substantially affected by the Brazilian inflation rate. Some of the Company's debts in Brazilian reais are indexed to inflation. generally adjusted with reference to the Extended National Consumer Price Index, an inflation index, such that inflation results in increases in the Company's financial expenses and debt service obligations. In addition, a significant portion of the Company's debt denominated in Brazilian reais is charged with interest in the CDI rate, which is partially adjusted for inflation. Effect of Foreign Sales on the Company’s Financial Performance The Company has production capacities installed outside Brazil, located in the United States, Germany and Mexico. In the fiscal year ended December 31, 2025, 40% of net revenue came from exports from Brazil and sales made through the United States and Europe and Mexico segments, compared to 42.3% in 2024 and 43.2% in 2023. In 2025, the world economy was impacted by a combination of protectionism, tariff wars, and persistent trade tensions, which reinforces global uncertainty. The year was marked by tariff increases in the United States, resulting in greater trade tensions, raising operating costs, fragmenting global chains and reducing investments. At the same time, the international scene continued to be pressured by conflicts such as the war between Russia and Ukraine and the conflict between Israel and Gaza. This combination of factors has intensified global economic fragmentation, put pressure on financial markets, and limited growth potential. Cyclical Events Affecting the Petrochemical Industry One of the key characteristics of the petrochemical industry is its cyclical nature, and historically, the global petrochemical market has experienced alternating periods of limited supply, leading to increased global prices and operating margins in the industry, followed by periods of adding production capacity, which puts pressure on utilization rates, global prices, and, consequently, operating margins in the industry. The increase in demand for petrochemicals and chemicals is related to the growth in global demand, which is impacted by macroeconomic factors such as interest rates, oil prices, shifts to alternative products, innovation, consumer trends, regulatory requirements, trade agreements, as well as logistical disruptions, pandemics or other global events. Therefore, the Company's results are influenced not only by its activities, but also by the dynamics of the global industry and by macroeconomic scenarios, over which the Company has no control and which may adversely affect its operating results. However, new opportunities may arise due to externalities, such as the change in consumer behavior, as an example derived from COVID-19. In 2025, spreads remained challenged, mainly due to the continued entry of new capacity into operation for PE and PP throughout the year, and uncertainties regarding trade tensions between the United States and China. In addition, oil prices were impacted by the economic uncertainty resulting from the tariff war, in addition to the gradual resumption of production by OPEC+, which contributed to adjustments in global supply, putting pressure on resin price references in the international market. The capacity rationalizations carried out in 2025 were not enough to reestablish the balance between supply and demand. In the longer term, the trend is for the current bear cycle to smooth out and eventually turn back into a boom cycle, as the industry waits to make decisions on new investments, while global trade rebalances and world demand absorbs new capacities. Additionally, projects announced to come online later in the future are more likely to be postponed or canceled, as the scenario may change, feedstock may become less advantageous and cost curves may change. Effects of fluctuating international prices for the main feedstock (naphtha, ethane, propane and propylene) Fluctuations in the international market price of naphtha have significant effects on the Company's costs of goods sold and on the prices it can charge its customers for its first and second generation products. Political instability in the Middle East or similar events that may occur, including the military conflict between Russia and Ukraine, and more recently the conflict between Israel, Hamas and Hezbollah, as well as other conflicts in the Middle East, can lead to unpredictable effects on the global economy or the economies of the affected regions. These events can have negative effects on oil production and price volatility, consequently leading to increased prices of naphtha and petrochemicals worldwide. The price of ethane and propane in the Mont Belvieu region of Texas and the Henry Hub in the United States are used as benchmarks for part of the Company's feedstock costs. Any future development that affects the balance between supply and demand of natural gas in the United States could adversely affect the price of natural gas at Mont Belvieu and Henry Hub (including, therefore, ethane, propane and butane) and increase the Company's production costs or decrease the price of petrochemicals. External factors and natural disasters, such as hurricanes, harsh winters or industrial developments, such as shale gas exploration, may disrupt the supply of natural gas, thereby increasing the cost, which may materially adversely affect the cost of goods sold and the results of the Company's operations. The price of propylene is based on the U.S. benchmark and is (i) produced by three different processes: refinery production (FCC), steam cracking, on-purpose production and PDH (propane dehydrogenator) process, with refineries being the main source of propylene in the United States; however, (ii) refineries can use propylene to make some products different. Their desire to sell propylene on the open market depends on the demand and price of gasoline, along with a few other chemicals. Effects of fluctuation of the international prices on the cost of goods sold Naphtha is the main feedstock used in the chemical operations that are part of the Brazil Segment. In 2025, naphtha and condensate accounted for 35.2% of the Company's consolidated direct and indirect cost of goods sold. The cost of naphtha varies according to prices in the international market, which fluctuates as a function of the balance of supply and demand for oil and other refined petroleum products. The Company purchases naphtha under a long-term supply agreement with Petrobras, and imports naphtha from other suppliers through the terminal in Aratú, in the State of Bahia, and the Petrobras terminal in Osório, in the State of Rio Grande do Sul. The prices that the Company pays for naphtha under these agreements, in addition to the supply agreement with Petrobras, are based on the market price of naphtha in the Amsterdam-Rotterdam-Antwerp (ARA) market. As a result, fluctuations in the ARA market price for naphtha have had a direct impact on the cost of the Company's first-generation products. The Company's contracts with Petrobras provide for naphtha prices based on ARA quotations. The volatility of the price of this product in the international market, the real/US dollar exchange rate and the level of carbon disulfide, a contaminant of the naphtha that is delivered, also influence the price of naphtha that the Company buys from Petrobras. The Company believes that these contracts have reduced the exposure of the cost of the Company's first-generation products to fluctuations in the ARA market price of naphtha. The price of naphtha in the international market has varied significantly in the past, and the Company expects it to continue to vary in the future. Significant increases in the price of naphtha and, consequently, in the cost of production of the Company's products, generally reduce its gross margins and operating results to the extent that it is not able to pass on all these increased costs to its customers, and may result in a reduction in the sales volume of its products. On the other hand, significant reductions in the price of naphtha and, consequently, in the cost of production of the Company's products, generally increase its gross margins, its operating results and may result in higher sales volumes, if this lower cost leads the Company to lower prices. In periods of high price volatility in U.S. dollars of naphtha, there is usually a lag between the time the U.S. dollar price increases or decreases and the time the Company is able to pass on higher costs. The Company does not currently hedge exposure to changes in naphtha prices because a portion of its sales are exports payable in foreign currencies and linked to international market prices of naphtha, and because the prices of polyethylene, polypropylene and PVC sold in Brazil generally reflect changes in international market prices of these products. The hedging strategy focuses on mitigating through swap operations, short-term price volatility and temporary distortions that may affect specific purchases that were not contracted based on a monthly average. These exposures are converted to a pricing structure at the monthly average, reducing sensitivity to daily price fluctuations and sporadic market movements. Effects of the fluctuation of the international prices on the prices of goods sold In Brazil, most of the prices of the Company's products are based on international references. The prices of products exported from Brazil are generally based on international spot market prices. The Company sets the prices of products sold in the United States and Europe based on market prices in those regions. The price of PE in Mexico is based on prices in the U.S. Gulf Coast region. The Company negotiates the prices in Brazilian reais of its products monthly. The Company seeks to revise its prices to reflect (i) changes in the prices in the international market of these products, which tend to vary in tandem with naphtha prices; and (ii) the appreciation or devaluation of the Brazilian real against the U.S. dollar. However, during periods of high volatility in international market prices or exchange rates, the Company may not be able to fully reflect these changes in its prices immediately. Capacity utilization The Company's operations are capital-intensive. In view of this, in order to obtain lower unit production costs and maintain adequate operating margins, the Company seeks to maintain high-capacity utilization rates in all its industrial units. The following table shows the capacity utilization rates related to the plants of some of the Company's main products in the periods presented: Fiscal Year Ended December 31, 2025 Ethene Brazil (Petrochemical Plants) 68% PE Brazil 68% PP Brazil 68% PVC Brazil 60% PP USA and Europe 74% PE Mexico 64% Effects of the Brazilian Industrial Policy SUDENE – Income Tax Reduction Since 2015, Braskem has obtained a tax benefit of a 75% reduction in corporate income tax on the income of the following industrial units: (i) PVC and chlorine soda units, established in the state of Alagoas; and (ii) chemical, PE and PVC units established in the city of Camaçari (BA). This benefit is valid for legal entities with projects for the implementation, modernization or expansion of industrial enterprises. The benefit can be used for a period of ten years. The tax benefit for the units in Camaçari (BA) was successfully renewed for an additional period of ten years, extending the benefits until 2033. The other units are in the process of renewing the tax benefit. In 2025, operations in Brazil recorded tax losses, so the benefit was not available for use. PRODESIN – ICMS Incentive Braskem has ICMS tax incentives in the State of Alagoas, through the Integrated Development Program of the State of Alagoas, or PRODESIN, which aimed to implement and expand a plant in that state. This incentive is considered a countervailing entry to the sales tax. In 2025, the amount was R$58 million (R$28 million in 2024). Special Regime for the Chemical Industry (REIQ) – PIS/COFINS Tax Incentive In 2025, the National Congress, considering the sensitive moment for the sector in Brazil and noting that several countries have supported their chemical industries through public policies, approved a bill that creates a new incentive program for the sector, called PRESIQ, considering that the taxes that make up the basis of the REIQ — PIS and COFINS — will be extinguished in 2026 due to the country's tax reform. PRESIQ consists of a financial credit for the sector in the total amount of R$3,000 million per year between 2027 and 2031, considering the industrial and investment modalities. Braskem also obtained approval for projects under the REIQ ("REIQ Investimentos") in order to receive an additional tax incentive at the rate of 1.5%, linked to investments in expansion of production capacity. We started to report these incentives through an accessory obligation called DIRBI. Based on data sent to the Federal Revenue of Brazil, in 2025, the total gross incentive of REIQ Investimentos reached R$629.3 million. Additionally, on March 20, 2026, Complementary Law No. 228 was published, providing for an increase, from 0.73% to 5.8%, in the benefit of the Special Regime for the Chemical Industry (“REIQ”), which corresponds to PIS/Cofins credits, levied on feedstock for the chemical and petrochemical industries, eligible for offsetting against federal taxes. Reintegra In December 2011, the Brazilian government implemented the "Reintegra" program, which aims to increase the competitiveness of Brazilian manufacturers in international markets, through the full or partial return of federal taxes on exports. Currently, the Reintegra program remains with a refund rate of 0.1%. This rate is expected to persist, as Brazil's Supreme Court ruled that Reintegra constitutes a tax subsidy for exporters. For the year ended December 31, 2025, the Company recognized in the result the amount of R$8 million of this tax credit. Pricing and Tariffs The Company defines the selling prices of ethylene with reference to international market prices. The prices paid by resin producers for imported petrochemical products reflect, in part, transportation costs, taxes and tariffs. The Company sets the prices of ethylene by-products, such as butadiene, by reference to various market factors, including the prices paid by resin producers for imported products, which also take into account transportation costs, taxes and tariffs. The Brazilian government has used import tariffs to implement economic policies. As a result, import tariffs applied to petrochemicals have varied in the past and may vary again in the future. Until September 2024, the import tax applied to Braskem's resins was 12.6%, according to the TEC level. Tariff adjustments could lead to increased competition from imports and cause Braskem to reduce its prices in the Brazilian market, with an impact on net revenue, which could negatively affect the Company's financial performance. In addition, products we export to the United States and Europe are subject to 6.5% tariffs. These tariffs generally balance the level of competition for the Company's locally produced products, and any future adjustments to these tariff structures could negatively impact our sales in these regions. Future trade agreements concluded by Brazil, Mercosur, the United States or the European Union may also lead to increased competition from imports and a reduction in domestic prices. Imports and exports within the South American Free Trade Area (Southern Common Market), or Mercosur, which is composed of Argentina, Brazil, Paraguay and Uruguay, have not been subject to tariffs since December 2001. Imports of suspended PVC from Bolivia, Chile, Colombia, Cuba, Ecuador, Israel, Peru and Venezuela are not subject to tariffs, due to a series of trade agreements. Suspended PVC imports from Mexico with reduced tariffs of 80% of the NMF, due to trade agreements. Measures implemented in 2025 The Executive Management Committee (Gecex) of the Chamber of Foreign Trade (Camex) approved the temporary increase in the import tax from 12.6% to 20% until October 16, 2026, for PE, PP and PVC resins sold by the Company, via inclusion in Camex's List of Temporary Tariff Increases due to Conjunctural Trade Imbalances. Trade defense measures Since the 1990s, PVC imports from the United States and Mexico have been subject to anti-dumping duties of 16.0% and 18.0%, respectively, which were imposed by the Brazilian Chamber of Foreign Trade (Câmara de Comércio Exterior), or CAMEX. The duties applied to imports from the United States and Mexico were revised in 2022 by the Brazilian government, which decided to extend until 2027 the application of antidumping duties for imports from the United States, with an ad valorem rate reduced to 8.2%, and for imports from Mexico, with a rate of 13.6%, but with immediate suspension of the application of antidumping duties for imports originating in Mexico. In June 2023, the Department of Trade Defense (DECOM) initiated a review of the anti-dumping duty applied to Brazilian imports of PVC obtained through suspension proceedings originating in the United States due to a change in circumstances that could lead to an increase in the duties applied. At the end of the investigation, the Brazilian authority concluded that the antidumping measure of 8.2% was not sufficient to neutralize the practice of dumping on PVC imports from the United States and decided to increase the duty to 43.7%, as published in Gecex Resolution No. 737, of May 28, 2025. The measure remains in force until September 19, 2027. Since 2008, PVC imports from China have also been subject to anti-dumping duties of 21.6%. These rights had been temporarily suspended in August 2020, but were reinstated in September 2021. In August 2025, the Brazilian government initiated a review of the anti-dumping duty applied to PVC originating in China to investigate the likelihood of recurrence of damage and dumping should the measure be terminated. The review was requested by Braskem and should be completed by August 2026. During the investigation period, the anti-dumping duty of 21.6% remains in force. In addition, in December 2010, CAMEX imposed an anti-dumping duty of 10.6% on imports of PP from the United States, which was extended in November 2016 and again in October 2022. In this latest review, the Brazilian government decided to extend the duties applied to PP imports from the United States until 2027, but with an immediate suspension of the application of antidumping duties. Subsequently, in February 2024, the Brazilian government decided to reapply anti-dumping duties to PP imports from the United States, at the ad valorem rate of 10.6%. In August 2014, the Brazilian government also imposed anti-dumping duties on PP imports from South Africa, India and South Korea, of 16.0%, from 6.4% to 9.9%, and from 2.4% to 6.3%, respectively. In December 2020, the Brazilian government extended the anti-dumping duties applied to imports of PP from India, reduced the duties applied to South Africa to a range between 4.6% and 16%, and ended the duties applied to South Korea. In December 2025, the Brazilian government initiated a review of the anti-dumping duty applied to the PP of South Africa and India to investigate the likelihood of recurrence of damage and dumping should the measure be terminated. The review was requested by Braskem and should be completed by December 2026. During the investigation period, the anti-dumping duties currently applied remain in force. In November 2024, the Department of Trade Defense (DECOM) initiated an original investigation to determine the existence of dumping in exports of polyethylene resins from the United States and Canada to Brazil, classified under subheadings 3901.10.30, 3901.20.29 and 3901.40.00 of the MERCOSUR Common Nomenclature (NCM), and the consequent damage to the domestic industry resulting from these practices. The investigation process can last up to 18 months. In August 2025, DECOM published a preliminary determination of the investigation, recommending the application of a provisional anti-dumping duty for six months to contain the damage to the domestic industry during the investigative period. Consequently, the provisional anti-dumping duty became applicable as of August 29, 2025, and will remain in force for six months. This measure imposes an anti-dumping duty of US$238.49 per metric ton on polyethylene imports originating in Canada and US$199.04 per metric ton on imports originating in the United States. Effect of Level of Indebtedness and Interest Rates In the fiscal year ended December 31, 2025, the Company's consolidated indebtedness, net of transaction costs, was R$66,128 million (US$12,018 million), including R$14,308 million (US$2,600 million), related to Braskem Idesa and its subsidiaries. The Company's level of indebtedness results in relevant financial expenses, reflected in the Company's Financial Statements. These expenses in Brazilian reais consist of interest expenses, including exchange rate variation of debts in relation to the dollar and other currencies, exchange gains or losses, among other items. In the fiscal year ended December 31, 2025, the Company recorded an expense totaling R$6,802 million associated, mainly (i) R$4,945 million related to interest expenses; (ii) R$861 million refer to the adjustment to present value – appropriation; and (iii) R$305 million refer to interest expenses on leases. A positive result of R$3,474 million related to hedges and exchange rate variations was also recorded, net in connection with the exchange rate variation on the Company's financial assets and liabilities. Effect of Taxes on The Company’s Income The Company is subject to various federal and state taxes in various jurisdictions and levied on its operations and results. The Company is subject to the Brazilian federal income tax of 25% (including surcharge) which, combined with the Social Contribution on Net Income – CSLL of 9%, totals a nominal rate of 34%, which is the standard corporate tax rate in Brazil. There are certain federal tax exemptions provided for in federal law that offer tax incentives to companies that set up their industrial operations in the state of Bahia. These exemptions represent a 75% reduction in the tax burden and, as a result, the Company is entitled to pay 25% of the statutory income tax rate on profits from the sale of: polyethylene, basic chemicals and PVC manufactured at one of its plants in the Complexo do Nordeste (State of Bahia) until 2033. The 75% exemption from the income tax rate, combined with the CSLL of 9%, allows the Company to pay 44.9% of the standard rate of 34% on profits from products manufactured in these plants. Accrued tax losses available for offsetting in Brazil do not expire. However, the annual compensation is limited to 30% of our adjusted taxable net income basis. This limit also applies to CSLL. The consolidated amount includes the impact of the different rates applicable in the countries where the foreign subsidiaries are located, which, as of December 31, 2025, were as follows: • Braskem Europe (Germany): 31.33% (including surcharges); • Braskem America and Braskem America Finance (United States): 21% + sales tax; • Braskem Argentina (Argentina): 35%; • Braskem Petroquímica Chile (Chile): 27%; • Braskem Netherlands, Braskem Netherlands Finance, Braskem Netherlands Inc. and companies from the Netherlands (Netherlands): 25.8%; • Braskem Idesa, Braskem Idesa Serviços, Braskem México, Braskem México Serviços and Braskem México Sofom (Mexico): 30%; • Braskem India (India): 25% (including surcharges). In addition, the introduction of a global minimum tax rate of 15% under the Pillar II Solution, agreed by more than 135 jurisdictions under the Organization for Economic Co-operation and Development (OECD)/G20 Inclusive Framework on Base Erosion and Profit Shifting (BEPS), brings an additional tax impact for countries where the effective tax rate is below 15%. Depending on the results by business segment, an additional tax (qualified domestic minimum supplementary tax) may be applicable to specific countries and/or there may be a supplementary charge by the country of the Ultimate Parent Entity of the Group (Income Inclusion Rule). The consolidated amount also includes the impact of taxation on a universal basis, introduced in Brazil by articles 76 and 77 of Law No. 12,973/2014. This law determines that the positive portions of the results earned by subsidiaries abroad will be computed in the calculation basis of the Corporate Income Tax (IRPJ) and CSLL in Brazil, individually. If the subsidiary has accumulated losses, these can be deducted up to the amount of the profit calculated; Thus, the legal entity is required to inform the tax authority of the accumulated losses in its annual income tax return. All profits earned by the subsidiaries mentioned above must be subject to IRPJ and CSLL taxation in Brazil, except for those earned by subsidiaries based in countries with which Brazil has a double taxation treaty. The profits of these companies will only be taxed when distributed to the respective parent companies. In addition, the universal taxation mechanism allows the use, as a tax credit, of the tax proven to be paid by the subsidiaries abroad (including the tax provided for in Pillar II paid abroad, as introduced by Law No. 15,079/2024), limited to the tax due on the profit of the subsidiary in Brazil at the rate of 34%. The legislation also allows the parent company in Brazil to apply a presumed credit of 9.0% on the profit earned by subsidiaries abroad that carry out industrial activity. Braskem applies this mechanism to its subsidiaries Braskem Europe GmbH, Braskem America Inc. and Braskem Idesa SAPI. Currently, the Company's exports are exempt from: (i) PIS – Social Integration Program, (ii) COFINS – Contribution to the Financing of Social Security, a federal value-added tax, (iii) IPI – Tax on Industrialized Products, and (4) ICMS – State Tax on the Circulation of Goods and Services. In the year ended December 31, 2025, management reassessed the recoverability of the deferred tax assets of the Company and its subsidiaries, in accordance with CPC 32 / IAS 12, considering all available evidence, positive and negative, on the existence of future taxable profits sufficient to realize the credits recorded. This process included, among others, the analysis of the recent history of results, the performance projections contained in the approved business plan, the expiration date of tax losses and the applicable tax planning strategies. Thus, in the year ended December 31, 2025, the deferred tax asset was written off in the amount of R$9,393, with an effect of R$7,054 on the year's income and R$2,339 on the comprehensive income Tax Reform in Brazil The new regulatory framework for consumption taxation in Brazil aims to simplify the tax system for transactions involving the sale of goods and services, with significant impacts on the petrochemical industry. This reform, established by Constitutional Amendment No. 132 at the end of 2023, was followed by the approval of regulatory legislation at the end of 2024. The federal consumption tax reform is expected to enter the testing phase in 2026 and fully take effect in 2027. Meanwhile, the implementation of state and municipal consumption taxes will follow a gradual transition period from 2029 to 2032. Braskem is conducting studies to assess the impacts of this reform and is working proactively to prepare for its implementation. It is believed that the reform will bring indirect benefits to the sector, including a simplified tax system, the possibility of taking advantage of tax credits on all taxed purchases of goods and services — and not just feedstock — and leaner internal processes. However, a gradual reduction in tax incentives is expected as the new regulatory framework comes into force. The Company is evaluating these effects to fully understand their implications. 2.2.b – Variations in revenues attributable to price changes, currency exchange rates, inflation, volume alterations and the introduction of the new products and services, and c) Impact caused by the inflation, the variations in prices for the most important inputs and products, the currency exchange and the interest rate in the Company’s operation income and the financial result, if applicable OPERATING INCOME The directors present below the analysis of the last fiscal year by segment of the Company: BRAZIL International Spreads: The spread of the main chemicals produced by Braskem was lower compared to 2024 (-13%), mainly due to the reduction in (i) the prices of the main chemicals given the lower price of propylene in the international market, mainly explained by the increase in the supply of propylene in the United States and the reduction in demand for PP during the period; (ii) the price of butadiene, mainly explained by the reduction in demand from the automotive sector; (iii) the price of benzene, mainly explained by the oversupply in the United States and the lower prices of oil and naphtha; and (iv) the prices of gasoline, mainly explained by the lower price of oil during the period. The PE spread decreased compared to 2024 (-7%) mainly due to (i) the lower PE price, given the increase in the supply of this product in the year; and (ii) the reduction of sea freight, which was higher in 2024, due to the conflicts in the Red Sea. The PP spread was higher compared to 2024 (+3%) mainly due to the lower price of naphtha in the period, mainly explained by the lower price of oil, influenced by the higher supply in the period, associated with the increase in production levels during the year. The PVC Par spread decreased by 20% compared to 2024, mainly explained by the lower price of PVC due to the reduction in demand from the civil construction sector given global interest rates, and offset by the reduction in oil prices. Demand: The demand for resins in the Brazilian market (PE+PP+PVC) in 2025 was 6.7 million tons, 2% lower when compared to 2024, mainly due to the lower demand for (i) PP influenced, mainly, by the durable consumer goods sector; and (ii) PE, mainly by the civil construction, automotive and household appliances sectors. These effects were partially offset by the higher demand for PVC, especially in the civil construction sector. Operational indicators: The average utilization rate of petrochemical plants in Brazil was 68% in 2025, 4 p.p. lower when compared to 2024, mainly explained by (i) the adjustments of production levels in the face of lower demand in the period; and (ii) scheduled maintenance shutdown at the Bahia petrochemical plant completed in January 2026. Resin sales in the Brazilian market totaled 3.2 million tons in 2025, 5% lower than the volume presented in 2024, mainly due to (i) the strategy of prioritizing sales with higher added value; and (ii) the lower volume of sales of PP and PE due to lower demand in the Brazilian market. Regarding the main chemicals, sales in the Brazilian market totaled 2.6 million tons in 2025, representing a reduction of 5% compared to 2024 mainly due to the lower sales volume of propylene, cumene, ethylene and paraxylene, explained by the lower demand in the period in the Brazilian market. Resin exports in 2025 totaled 0.9 million tons, representing an increase of 7% compared to 2024, mainly due to the higher volume of PE and PP exports to South America given the greater availability of products as a result of the lower demand in the Brazilian market by 3%. Exports of main chemicals totaled 0.2 million tons, a reduction of 27% compared to 2024, mainly due to the lower volume of exports of (i) gasoline, due to the prioritization of serving the Brazilian market; (ii) benzene, impacted by import tariffs in the US; and (iii) toluene, due to the lower demand related to the greater supply of substitute products in the Brazilian market. Net revenue from sales and services in the Brazil segment decreased by R$3,070 million, or 6%, from R$54,844 million in 2024 to R$51,774 million in 2025, mainly explained by the reduction of (i) 5% or 175 thousand tons in the volume of sales of resins in the Brazilian market; (ii) 13% in the average international price reference of main chemicals; (iii) 5% or 128 thousand tons in the sales volume of the main chemicals in the Brazilian market; (iv) 10% in the average international reference price of resins; and (v) 27% or 72 thousand tons in the export volume of the main chemicals in the international market. Additionally, in 2025 the revenue of the Brazil segment was positively impacted by around R$583 million (US$106 million) of PIS/COFINS credits related to REIQ Investimentos, calculated in accordance with current legislation. The cost of goods sold in the Brazil segment decreased by R$1,949 million, or 4%, from R$50,600 million in 2024 to R$48,651 million. In 2025, the COGS of the Brazil segment was impacted by the provision of shutdown of the chlor- alkali plant in Alagoas, within the scope of Transforma Alagoas, which aims to make PVC production more competitive and sustainable, by R$546 million (US$100 million). Excluding the above effect, the reduction in dollars (-8%) and Brazilian reais (-5%) is mainly explained by the reduction of (i) 14% and 4% in the international references of naphtha and propane, respectively; (ii) 5% or 175 thousand tons in the volume of resin sales in the Brazilian market; and (iii) 5% or 128 thousand tons in the sales volume of main chemicals in the Brazilian market. These effects were partially offset by the impact of R$85 million (US$14 million) increase in idle costs and scheduled shutdowns during 2025 compared to 2024, mainly related to scheduled maintenance shutdowns carried out at the petrochemical plants in Rio de Janeiro, during 3Q25, and Bahia, during 4Q25. Additionally, during 2025, COGS was positively impacted by PIS/COFINS credits on the purchase of feedstock (REIQ) by R$273 million (US$46 million) and by Reintegra credits by R$8.4 million (US$1.5 million). In this sense, in 2025 the gross profit of the Brazil segment was R$3,123 million, lower by R$1,122 million compared to 2024, when it presented gross profit of R$4,244 million. UNITED STATES AND EUROPE International spreads: The PP spread in the United States remained in line compared to 2024 mainly due to (i) the reduction in the price of PP, explained by the reduction in the price of propylene with the increase in supply during the year given the normalization of utilization rates in the region; and (ii) the reduction in the price of propylene explained, mainly, due to the increase in the supply of propylene. The PP spread in Europe in 2025 was 34% lower compared to 2024, mainly due to the lower PP price given the lower demand from the civil construction, home appliances and automotive sectors during the period. Demand: PP demand in North America remained in line when compared to 2024, mainly explained by the optimization of inventory levels in the transformation chain associated with the maintenance of demand levels compared to the previous year. PP demand in Europe was higher by 3% when compared to 2024, mainly due to the anticipation of purchases in the transformation chain during 4Q25, explained by the reduction in the price of PP Europe (-7%), combined with the increase in China's production capacity during the period, resulting in higher levels of imports to Europe. Operational indicators: The average utilization rate and sales volume of PP in the United States and Europe segment remained in line when compared to 2024. Net revenue from the U.S. and Europe segment decreased by R$3,044 million, or 16%, to R$16,400 million in 2025, compared to R$19,444 million in 2024, due to the 17% and 7% reduction in international PP price references in the United States and Europe, respectively. The cost of goods sold in the United States and Europe segment decreased R$1,747 million, or 10%, to R$16,279 million in 2025 from R$18,026 million in 2024, mainly as a result of the 24% and 1% reduction in international propylene price benchmarks in the United States and Europe, respectively. In the fiscal year ended December 31, 2025, gross profit in the United States and Europe segment was lower by R$1,297 million, or 91%, to R$121 million in 2025, from R$1,418 million in 2024. MEXICO Spread internacional: The PE spread in North America, in 2025, decreased by 19%, mainly due to the lower PE price, mainly explained by (i) the oversupply of this product in the year, and the reduction in sea freight, which was higher in 2024, due to the conflicts in the Red Sea; and (ii) the higher price of ethane due to, mainly, the increase in the price of natural gas and the higher demand for ethane in the period. Demand: PE demand in Mexico was 2.6 million tons in 2025, an increase of 3% compared to 2024, mainly due to the increase in inventory formation in the chain related to (i) tariff uncertainties in the United States; and (ii) expectations of increased PE prices. The utilization rate of the PE plants was 64% in 2025, 14 p.p. lower than in 2024, mainly explained by the scheduled general maintenance shutdown at Braskem Idesa's petrochemical plant in 2Q25 and 3Q25. The average supply of ethane during the year was approximately 41 thousand barrels per day, lower than the average of about 50 thousand barrels per day supplied in 2024. Operational indicators: In 2025, PE sales were 16% lower when compared to 2024, totaling 708 thousand tons, mainly explained by the lower availability of product for sale in 2Q25 and 3Q25 due to the general maintenance shutdown carried out in these quarters. Net revenue from the Mexico segment decreased by R$1,045 million, or 20%, to R$4,103 million in 2025 from R$5,148 million in 2024, mainly due to (i) a reduction of 138 thousand tons, or 16%, in PE sales volume in the year; and (ii) a 12% reduction in the international PE price reference in the international market. The segment's cost of goods sold in Mexico increased by R$1,699 million, or 38%, to R$6,200 million in 2025 from R$4,501 million in 2024, mainly due to the recording of impairment loss in the amount of R$1,468 million, after the identification that Braskem Idesa's recoverable amounts of assets were lower than the respective book values. In the fiscal year ended December 31, 2025, gross profit in the Mexico segment decreased by R$2,744 million, to a negative value of R$2,097 million in 2025, from R$647 million in 2024. CONSOLIDATED Adjusted Consolidated EBITDA Adjusted Consolidated EBITDA was lower by R$2,603 million, from R$5,759 million in 2024 to R$3,156 million in 2025. The reduction compared to 2024 is mainly explained by the reduction of R$4,441 million in gross profit, from R$5,997 million in 2024, to R$1,556 million in 2025, due to the reduction of R$6,694 million in net revenue compared to 2024. These effects were partially offset by (i) the provisions of a contractual fine to be received on the delay in the construction of the ethane import terminal in Mexico of R$225 million; (ii) the reduction of R$173 million in the constitution of provisions for the repair of environmental damages; (iii) the adjustment in the appraisal report related to the sale of Cetrel, of R$43 million; and (iv) the increase of R$33 million in disposals of fixed assets mainly due to the sale of railcars in the United States. 2.2.c – Impact of inflation, price variation of the main inputs and products, exchange rate and interest rate in the operating result and in the financial result of the Company, when relevant The information related to this item 2.2(c) is described in item 2.2(a) (ii) of this Form. 2.3 – Officers' comments on changes in accounting practices/modified opinions and emphases: 2.3.a – Changes in accounting practices that have resulted in significant effects on the information provided for in fields 2.1 and 2.2 Material changes in accounting practices There were no significant changes in accounting practices in the fiscal year ended December 31, 2025. Significant effects of changes in accounting practices There are no significant events of changes in accounting practices in the individual and consolidated financial statements for the fiscal year ended December 31, 2025. 2.3.b – Modified opinions and emphases in the auditor's report Commentary on the Independent External Auditors' Report on the Individual and Consolidated Financial Statements for the Year Ended December 31, 2025 The report of the Company's independent auditors on the individual and consolidated financial statements for the fiscal year ended December 31, 2025, did not contain any reservations. Regarding the paragraph of emphasis referring to material and significant uncertainties about the Company's operational continuity, it should be noted that several pieces of evidence were presented to the auditors on the measures that are currently being adopted to address the deterioration of the Company's financial situation, arising, among others, from the prolonged global downturn in the petrochemical industry. In addition, in this scenario, no impacts of the recent armed conflicts in the Middle East were considered, with relevant impacts on petrochemical inputs and logistics chains that impact the sale prices of the Company's products. 2.4 – Officers' comments on relevant effects on FDs Directors should comment on the material effects that the following events have caused or are expected to have on the issuer's financial statements and results: 2.4.a – Introduction or disposal of an operating segment There was no introduction or sale of an operating segment in the fiscal year ended December 31, 2025. 2.4.b – Incorporation, acquisition or disposal of ownership interest In June 2025, the Company completed the sale of its entire interest in B&TC B.V. ("B&TC"), which holds 100% of the shares of ER Plastics B.V. ("ER Plastics"), and its wholly owned subsidiary ER Plastics, which operates in the mechanical recycling of mixed plastic waste into compression molded parts (construction plates and pallets). As a result of this operation, the Company recognized a loss of R$96 million. In January 2025, the Company decided to reevaluate and discontinue new investments in Oxygea, Braskem's vehicle focused on digital transformation with startups in the market. This decision is in line with the Company's strategic direction of prioritizing its assets and investments, both operational and strategic. As of December 31, 2025, the balance of the investment in Oxygea was R$79 million. In May 2025, four more Special Purpose Entities ("SPEs") were incorporated owned by Braskem Trading and Shipping B.V., a company indirectly controlled by the Company, with the main objective of entering into certain ocean freight agreements and certain commercial transactions for the purchase and sale of chemical and petrochemical products, namely: Mares do Futuro Shipping B.V., Baita Futuro Shipping B.V., Bravo Futuro Shipping B.V. and Fortunate Future Shipping B.V. In June 2025, the Company concluded the acquisition of 100% of the class B common shares of Serra das Almas F1 Holding S.A. ("Serra das Almas"), equivalent to 49% of its voting capital and 24.5% of its total capital, now holding an indirect interest in five SPEs controlled by Serra das Almas, holders of the authorization for the generation of wind energy from wind farms, namely: Serra das Almas I S.A. Wind Farm, Serra das Almas III S.A. Wind Farm, Serra das Almas IV S.A. Wind Farm, Serra das Almas V S.A. Wind Farm and Serra das Almas VI S.A. Wind Farm. In August 2025, the Company concluded the acquisition of 100% of the Class B Common Shares of the company Folha Larga 1 Holding S.A. ("Folha Larga"), equivalent to 49.89% of its voting capital and 24.95% of its total capital, now holding an indirect interest in four SPEs controlled by Folha Larga and holding the authorization for the generation of wind energy from wind farms namely: Wind Farm Ventos de São Januário 01 S.A., Wind Farm Ventos de São Januário 04 S.A., Wind Farm Ventos de São Januário 13 S.A. and Wind Farm Ventos de São Januário 14 S.A. 2.4.c – Unusual events or operations 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 phenomenon 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 agreement in progress: i) Instrument of 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) Instrument of Agreement to Dismiss the Public-Interest Civil Action on 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. Following ratification by the courts of this agreement, the Public-Interest Civil Action for Socio-environmental Reparation was dismissed; iii) Instrument of Agreement for Implementation of Socioeconomic Measures for the 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 3rd Federal Court of Maceió, which establishes the adoption of requalification actions in the Flexais region, compensation to the Municipality of Maceió and indemnities to the residents of this location; iv) iv) Instrument of Global Agreement with the Municipality of Maceió (“Instrument of Global Agreement”) ratified on July 21, 2023 by the 3rd Federal Court of Maceió, which establishes, among other things: (a) payment of R$1.7 billion as indemnity, compensation and full reimbursement for any property and non-property damages caused to the Municipality of Maceió; (b) adherence of the Municipality of Maceió to the terms of the Socio-environmental Agreement, including the Social Actions Plan (PAS); and v) Instrument of Agreement with the State of Alagoas (“State Agreement”), executed on November 10, 2025, which provides, among other terms: (a) a total amount of R$ 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 R$ 1.2 billion established in the State Agreement, R$ 139 million (on an updated basis) had already been paid. The remaining balance must be paid in 10 adjusted variable annual installments, mainly after 2030, considering the Company’s payment capacity. The Company's Management, based on its assessment and that of its external advisers, taking into account the short and long-term effects of technical studies prepared, available information and the best estimate of expenses for implementing the measures related to the geological event in Alagoas, presents the following changes to the provision in the fiscal years ended December 31, 2025 and 2024: Provisions - Geological event Alagoas On 31 December in R$ million 2025 2024 Balance at the beginning of the year 5,570 5,240 Provisions (*) 320 2,237 Paymen and reclassifications (**) (2,594) (2,052) Realization of present value adjustment 207 145 Total 3,503 5,570 Current liabilities 1,107 2,436 Non-current liabilities 2,396 3,134 Total 3,503 5,570 (*) a) The variation in the provision for the fiscal year ended December 31, 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; (ii) the implementation and advancement in the maturity of projects; and (iii) initiatives and programs present in Alagoas. b) Includes inflation/foreign exchange adjustment of R$ (4) million (2024: R$ 114 million) reported under Financial expenses. Note 2: Of this amount, R$1,348 million (2024: R$1,819 million) refer to payments made and reclassifications of R$1,246 million (2024: R$233 million) for the Other obligations group, which totals a balance of R$1,416 million (2024: R$478 million) referring to accounts payable from the Geological Event in Alagoas. The current provision can be segregated into the following action fronts: a. Support for relocation and compensation: Refers to initiatives to support relocation and compensation of the residents, business and real state owners of properties located in the Civil Defense Map, including indemnifications that require special measures for relocation, such as hospitals, schools and public equipment, either pertaining to private entities or the government. These actions have a provision of R$192 (2024: R$997) comprising 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 mining areas. The closure plan of 35 mining areas currently considers the following: (i) 18 cavities are expected to be filled with solid material with priority. To date, 6 cavities have already been filled with sand, 4 cavities reached the technical filling limit, 6 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 the need for additional measures to date; (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 amount of R$ 1,730 million (2024: R$ 2,607 million) to implement the 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 change based on new information, such as the results of monitoring of the cavities, the progress of implementing the plans to close mining areas, possible changes that may be required in the environmental plan, the 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, occurred 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, were completed. The report was submitted to the authorities. c. Socio-urban measures: Refers to actions to implement 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 related to urban mobility. To date, of the 11 projects defined for urban mobility, 6 have already been completed, 3 are in progress and the remaining 2 projects are in the planning stages. 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 (2 are completed and 8 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$793 million (2024: R$1,141 million). d. Additional measures: Refer to actions related to: (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 current balance of additional measures described in this item totals R$788 million (2024: R$825 million). On November 10, 2025, Braskem and the State of Alagoas entered into the State Agreement, providing for a total payment of R$ 1.2 billion, of which R$ 139 million (on an updated basis) had already been paid. The remaining balance, classified to Other liabilities, must be paid in 10 adjusted variable annual installments, mainly after 2030. The Company had previously recorded a provision of R$ 467 million for compensation of property damages to the State of Alagoas. The State Agreement establishes compensation, indemnification and/or reimbursement to the State of Alagoas for the full reparation of all property and non-property damages at the state level and grants the Company full discharge from any damages arising from and/or related to the geological event in Alagoas, including the termination of the State of Alagoas’ indemnification lawsuit. 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; and possible 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, are in progress, and additional measures may become necessary and will be implemented as part of the measures for a Plan to Recover Degraded Areas (“PRAD”). The Company has been making progress in negotiations with private entities and government authorities about other indemnification claims, deepening its understanding, 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 their 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"). In October 2025, the MPF filed charges based on the final report of the Federal Police from October 2024. The Company reaffirms that it is, and has always been, available to the authorities and will provide its statements at the appropriate time in the legal proceedings. Furthermore, it is not possible to anticipate all new claims, related to damages 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 infraction 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, Municipality or Federal level. Therefore, the number of such actions, their nature or the amounts involved cannot be estimated. 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 differ significantly from its estimates and provisions. Legal actions in progress The contingent liabilities with a prognosis of loss assessed as possible by the Company's management, based on its assessment and that of its external legal advisors, related to the geological event in Alagoas, are disclosed as follows (in millions of Brazilian reais): Ongoing lawsuits - Alagoas geological event in R$ million On 31 December 2025 2024 Civil proceedings – Alagoas (1) 8,036 9,241 Environmental processes – Alagoas 96 85 Total (2) 8,132 9,326 Note 1: Amounts presented net of the portion of the provision for compensation and relocation of public 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$ 103 million. Note 2: Comprise the lawsuits with possible loss prognosis detailed below, and others of lesser value involved, including Public Civil Actions related to the relocation of certain public facilities located in the region. See explanatory note "23.1 – Ongoing lawsuits" of its Financial Statements as of December 31, 2025 for more information on these ongoing lawsuits related to the Alagoas Geological Event. Leniency Agreement 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 (Ministério Público Federal, hereinafter “MPF Agreement”) and with U.S. and Swiss authorities (“Global Settlement”), in the amount of US$ 957 million (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 (Controladoria-Geral da União, hereinafter “CGU”) and the Office of the Attorney General (Advocacia-Geral da União, hereinafter “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 million 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. Therefore, no additional payments are expected to be made by the Company. Since 2016, The Company has paid R$ 3,405 million, distributed as shown below: Payments per entity in R$ million Cumulative amounts as of December 31, 2025 AGU, CGU and MPF DoJ (1) OAG (1) MPF SEC (1) Total Payments Made 1,213 297 407 1,282 206 3,405 Nota 1: U.S. Department of Justice (“DoJ”); Swiss Office of the Attorney General (“OAG”) e U.S. Securities Exchange Commission (“SEC”). In August 2023, the Company was notified by 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 (Superior Tribunal Federal, hereinafter “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 Leniency 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) 2025: BRL35 million (ii) 2026: BRL35 million (iii) 2027: BRL55 million (iv) 2028 to 2030: installments of about R$158 million each. The CGU/AGU Amendment will be submitted for 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 million in the amount of the provision of the leniency agreement. On December 31, 2025, the balance payable adjusted by the SELIC is R$673 million, with the amount of R$90 million recorded in current liabilities and the amount of R$583 million in non-current liabilities. 2.5 – Non-accounting measurements Consistent with market practices, the Company discloses non-accounting measures that do not consist of measures of financial performance in accordance with the Accounting Practices Adopted in Brazil and the International Financial Reporting Standards ("IFRS"). Management believes that the presentation of these measures provides useful information for shareholders and the market in general to have a better understanding of the Company's operating performance and financial results. However, these non-accounting measures do not have standardized meanings and methodologies and may not be directly comparable with metrics of the same or similar name published by other companies due to different calculation methodologies or due to items that may be subject to interpretation. Although non-accounting measures are frequently used by the general market and by the Company's management to analyze its financial and operating position, shareholders and the market in general should not base their investment decisions on this information as a substitute for accounting measures or as an indication of future results. The information included in this item 2.5 was prepared based on the Company's Financial Statements and should be read and analyzed in conjunction with the information contained in the Company's individual and consolidated financial statements and their respective explanatory notes, available on the Company's Investor Relations website (www.braskem-ri.com.br) and on the CVM website (www.cvm.gov.br). 2.5.a – Inform the value of non-accounting measures Non-accounting measurements December 31, 2025 In R$ million Consolidated EBITDA 2,866 Adjusted Consolidated EBITDA 3,156 Consolidated EBITDA Margin (%) 4% Adjusted Consolidated EBITDA Margin (%) 4% Adjusted EBITDA excluding Braskem Idesa and its subsidiaries 2,864 Consolidated Gross Debt 66,188 Debt Braskem Idesa and its subsidiaries 14,308 Adjusted Gross Debt (excluding Braskem Idesa and its subsidiaries) 51,881 Consolidated Cash & Marketable Securities 11,867 Caixa Braskem Idesa and its subsidiaries 233 Exclusive Cash of Alagoas 138 Reserve Account¹ 122 Cash and Financial Investments (excluding Braskem Idesa and its subsidiaries, Exclusive Cash of Alagoas and Reserve Accounts) 11,373 Net Debt 40,507 Global Agreement 673 Adjusted Net Debt 41,180 Financial Leverage in R$ 14.38x Note (1) Regarding reserve accounts linked to the fulfilment of contractual obligations.

Consolidated EBITDA, Adjusted Consolidated EBITDA, Adjusted EBITDA excluding Braskem Idesa and its subsidiaries, Consolidated EBITDA Margin, Adjusted Consolidated EBITDA Margin Consolidated EBITDA is a non-accounting measure prepared by the Company in accordance with CVM Instruction No. 527, of October 4, 2012 ("CVM Instruction 527"), reconciled with its financial statements and corresponds to the net income (loss) for the period plus (i) income tax and social contribution - current and deferred; (ii) net financial income; and (iii) depreciation and amortization. Based on Consolidated EBITDA, the Company discloses the consolidated non-accounting measurements Adjusted Consolidated EBITDA, Adjusted EBITDA excluding Braskem Idesa and its subsidiaries, Consolidated EBITDA Margin and Adjusted Consolidated EBITDA Margin. The Company defines Consolidated Adjusted EBITDA as Consolidated EBITDA plus (i) impairment loss of approximately R$1,415 million in the Mexico segment; (ii) the result of the hibernation of the chlor-alkali plant in Alagoas in the amount of R$797 million; (iii) the (Reversal) provision of the geological event in Alagoas of R$324 million; (iv) the discount related to the sale of credit rights of R$208 million; (v) the Provision (reversal) for losses of long-term assets in the amount of R$105 million; (vi) the Result of equity interests in the negative amount of R$9 million; (vii) the reversal of the withholding tax provision of Braskem Netherlands B.V. related to the concepts of international tax reform (Pillar Two) in the negative amount of R$150 million; (viii) the result of the recognition of the PIS/COFINS credit in the negative amount of R$293 million; (ix) the result of the recognition of presumed PIS/COFINS credits under the Industrial REIQ and the REIQ Investments in the negative amount of R$437 million; and (x) the tax credit in the negative amount of R$1,670 million referring to the deduction of Cide-Combustíveis paid from the PIS/COFINS due on the sale of gasoline since 2004. Adjusted EBITDA excluding Braskem Idesa and its subsidiaries corresponds to the Consolidated Adjusted EBITDA, mentioned above, subtracted from the EBITDA of Braskem Idesa and its subsidiaries as well as the consolidation effects of the companies. The Consolidated EBITDA Margin corresponds to the percentage of Consolidated EBITDA divided by the consolidated net revenue from sales and services, and the Adjusted Consolidated EBITDA Margin corresponds to the percentage of the Consolidated Adjusted EBITDA divided by the consolidated net revenue from sales and services. The Company uses the non-accounting indicators Consolidated EBITDA, Consolidated Adjusted EBITDA, Adjusted EBITDA excluding Braskem Idesa, Consolidated EBITDA Margin and Adjusted Consolidated EBITDA Margin to measure its consolidated operating performance, as it believes it facilitates the comparability of its structure over the years, since they correspond to indicators used to evaluate the financial results of a Company, without the influence of its capital structure, tax and financial effects. Consolidated EBITDA, Consolidated Adjusted EBITDA, Adjusted EBITDA excluding Braskem Idesa and its subsidiaries, Consolidated EBITDA Margin and Consolidated Adjusted EBITDA Margin are not measures established in accordance with international accounting standards (IFRS) and are only additional information to its financial statements and should not be used as (i) the basis for dividend distribution; (ii) substitutes for net income and operating cash flow; (iii) operational performance indicators, in isolation from other accounting indicators; or (iv) liquidity indicators, separately from other accounting indicators. Consolidated Gross Debt, Adjusted Net Debt and Financial Leverage (Consolidated Net Debt/Adjusted Consolidated EBITDA) The Company's Consolidated Gross Debt corresponds to the sum of financing and debentures (current and non-current). The Consolidated Gross Debt minus cash and cash equivalents, and minus the financial investments (current and non-current), results in the Company's Consolidated Net Debt. Based on Consolidated Net Debt and Consolidated Adjusted EBITDA, the Company discloses the non-accounting measure Financial Leverage, which is calculated as Adjusted Consolidated Net Debt divided by Adjusted Consolidated EBITDA for the last twelve months. Consolidated Gross Debt, Net Adjusted Debt and Financial Leverage are not measures established in accordance with international accounting standards (IFRS) and have no standard meaning. Other companies may calculate Consolidated Gross Debt, Adjusted Net Debt and Financial Leverage differently from the Company. The Company understands that the measurements of Consolidated Gross Debt, Adjusted Net Debt and Financial Leverage are useful in assessing the degree of financial leverage in relation to operating cash flow. 2.5.b – Make conciliations of reported values and the audited financial statement figures Consolidated EBITDA, Adjusted Consolidated EBITDA, Consolidated EBITDA Margin and Adjusted Consolidated EBITDA Margin Consolidated Values Fiscal Year Ended December 31, 2025 in R$ million Net profit (loss) for the period (10,960) (+) Income tax and social contribution – current and deferred 8,116 (+) Financial result 1,038 (+) Depreciation and amortization 4,673 Consolidated EBITDA (1) 2,866 (+) Provision (reversal) for long-lived asset losses (2) 105 (+) Income from equity interests (3) (9) (+) Leniency Agreement - (+) (Reversal) provision of the geological event in Alagoas (4) 324 (+) CS-AL hibernation provision 979 (+) Others non-recurring (926) Adjusted Consolidated EBITDA (1) 3,156 Consolidated Net Sales and Service Revenue 70,717 Consolidated EBITDA Margin (%) 4% Adjusted Consolidated EBITDA Margin (%) 4% Note 1: Consolidated EBITDA and Consolidated Adjusted EBITDA correspond, respectively, to Basic EBITDA and Recurring EBITDA in other documents disclosed by the Company including, but not limited to, quarterly earnings releases, investor presentations, annual management report and Sustainability report.

It is worth mentioning that Consolidated EBITDA, Adjusted Consolidated EBITDA, Adjusted EBITDA excluding Braskem Idesa and its subsidiaries, Consolidated EBITDA Margin and Adjusted Consolidated EBITDA Margin are additional information to the financial statements and should not be used as a substitute for audited results as they are not measures recognized by the accounting practices adopted in Brazil or by international accounting standards (IFRS). Consolidated Gross Debt, Consolidated Net Debt and Financial Leverage (Consolidated Net Debt/Adjusted Consolidated EBITDA The Company understands that the measurements of Consolidated Gross Debt, Consolidated Net Debt and Financial Leverage (Consolidated Net Debt/Consolidated Adjusted EBITDA) better reflect its indebtedness and financial leverage. It is worth noting that the Consolidated Gross Debt, Consolidated Net Debt and Financial Leverage (Consolidated Net Debt/Adjusted Consolidated EBITDA) are additional information to the financial statements and may be supplementary measures for shareholders and the market in general in their analysis of the Company's financial condition and operating performance. 2.6 – Events subsequent to the financial statements The Company's Consolidated Financial Statements for the fiscal year ended December 31, 2025 were approved by the Company's Board of Directors and issued on March 26, 2026. The following events were verified subsequent to the financial statements for the fiscal year 2025, pursuant to the rules set forth in Technical Pronouncement CPC 24, approved by CVM Resolution No. 105/2022: In January 2026, the Company became aware of the filing of a Public Civil Action by the DPE and the Association of Entrepreneurs and Victims of Braskem, claiming material and moral damages for entrepreneurs who explore businesses in the edge of the map area. Additionally, in an injunction, they request the creation of an emergency fund to support entrepreneurs, with an initial contribution by Braskem of R$400 thousand to subsidize loans for the benefit of entrepreneurs. The plaintiffs attributed the amount of R$2billion to the case. The Company, supported by the opinion of its external legal advisors, classifies the chance of losing the lawsuit as possible. In the first quarter of 2026, the Company was notified of two new tax assessments totaling R$ 1.2 billion, relating to various federal taxes offset against non-cumulative PIS and COFINS credits generated as a result of the exclusion of ICMS from the calculation bases of such contributions. Based on the opinion of its external legal counsel, the Company assesses the likelihood of loss in this action as possible. 2.7 – Allocation of results (a) rules on retention of profits The Company's Bylaws do not provide for any statutory reservation, as provided for in Article 194 of Law No. 6,404, of December 15, 1976, as amended ("Brazilian Corporation Law"). However, the Company's Shareholders' Meeting may resolve on the constitution of other reserves, as well as on the retention of profits, as established in the Brazilian Corporation Law. (a.i) amounts withheld from profits In the fiscal year ended December 31, 2025, the Company recorded a loss. (a.ii) percentages in relation to total reported profits Not applicable, given that the Company recorded a loss in the fiscal year ended December 31, 2025. (b) rules on dividend distribution Mandatory dividend: According to the Company's Bylaws, 25.0% of the net income for the year will be allocated to the payment of mandatory dividends, subject to the legal and statutory advantages of Class "A" and "B" preferred shares. Priority dividend: Class "A" and "B" preferred shares have equal priority in the distribution in each fiscal year, of a minimum, non-cumulative dividend of six percent (6%) on their unit value (obtained by dividing the capital stock by the total outstanding shares), according to the profits available for distribution to shareholders. Common shares will only be entitled to dividends after the payment of dividends from preferred shares. After the provisions of the previous paragraph have been complied with and the common shares are guaranteed a dividend of six percent (6%) levied on their unit value, the class "A" preferred shares shall compete on equal terms with the common shares in the distribution of remaining profit. Class "B" preferred shares will not participate in remaining profits after they receive the minimum dividend referred to above. If there is a surplus of the mandatory dividend after the payment of the priority dividend, it will be applied: in the payment of a dividend to the common shares up to the limit of the priority dividend of the preferred shares; and if there is still a remaining balance, in the distribution of an additional dividend to the common shares and to the class "A" preferred shares, under equal conditions, so that each common or preferred class "A" share receives the same dividend. (c) Periodicity for dividend distributions In accordance with the Brazilian Corporation Law and the Company's Dividend Policy, the resolution on the allocation of the Company's net income, calculated annually based on the Company's audited financial statements, is incumbent upon the Annual Shareholders' Meeting to be held within the first four months following the end of the fiscal year. Without prejudice, the Company is entitled to draw up quarterly and/or semiannual balance sheets and, if there is a profit, the Board of Directors may approve the distribution of advance dividends, with the ad referendum distribution of the Shareholders' Meeting being prohibited, pursuant to paragraph 4 of article 47 of the Bylaws and subject to the legal provisions. In addition, the Board of Directors may declare interim dividends, to the account of retained earnings or existing profit reserves, under the terms of the Law and the Bylaws.

In addition, the Company announced the execution of projects within the scope of REIQ Investimentos, which consists of the presumed credit of 1.5% of PIS/COFINS linked to investments in the expansion of the installed capacity of the Brazilian chemical industry. In 2025, the Company advanced in the implementation of projects and recorded around R$322 million in net tax credits through REIQ Investimentos. This amount is mainly related to investments for the implementation of the Transforma Rio project, in technology for efficiency in the resin chain and in the adaptation of the process for the industrial production of new copolymer grades. Regarding Braskem Idesa, investments at the end of 2025 totaled about R$896 million (US$160 million), of which (i) R$397 million (US$70 million) are related to the completion of the construction of the ethane import terminal, through Terminal Química Puerto México (TQPM); and (ii) R$499 million allocated mainly to scheduled shutdown of general maintenance, asset reliability and integrity initiatives and Safety, Health and Environment ("HSE"). 2026 Investments The total investments expected to be made in 2026 by Braskem (ex- Braskem Idesa and ex-REIQ Investimentos) is R$2,565 million, which will be used mainly for: (i) scheduled maintenance shutdowns of the petrochemical plant in Rio Grande do Sul and other resin plants in Brazil; (ii) regulatory and safety-related investments (iii) mechanical integrity of assets and acquisition of spare parts for operational continuity; (iv) investments in technological developments and (v) acquisition of industrial land in the Duque de Caxias industrial complex in Rio de Janeiro. In October 2025, the Board of Directors approved the investment to increase the ethane base capacity of its petrochemical plant in Rio de Janeiro by 220 thousand tons of ethylene per year and equivalent volumes of polyethylene. The total estimated value of the investment in the Project is approximately R$4.2 billion, which may vary by up to 30% given the current stage of maturity of the Project. The implementation of the Project, estimated to be completed by the end of 2028, is conditional on obtaining financing, in addition to the resources already approved under the REIQ Investments benefit for 2025 and 2026. With respect to Braskem Idesa and its subsidiaries, the total investment expected to be made in 2026 is R$242 million (US$44 million), of which approximately R$234 million (US$42 million) will be directed to operational investments in the maintenance and operation of the petrochemical complex and to projects related to operational efficiency, such as maintenance, productivity and HSE), and about R$8 million (US$2 million) will be directed, mainly, to expenses with people, considering the commissioning phase of the terminal. (ii) Sources of financing for investments The Company seeks to finance its investment plan preferably, with financing lines contracted with government agents (including development institutions), both Brazilian and international. In addition, the Company uses a presumed credit of 1.5% PIS/COFINS linked to REIQ Investimentos, applicable to projects eligible for the Brazilian chemical industry. The financing decision depends on the Company's financial strategy and the eligibility of investments for available lines. (iii) ongoing relevant divestments and planned divestments At the end of 2025, there was no process of total divestment of material and strategic assets in progress. In line with its strategic pillars, Braskem maintains its focus on return on invested capital, strengthening its leadership and growth in biopolymers. In this context, the Company constantly evaluates its portfolio of assets in order to guide its strategic decisions for potential future divestments. 2.10.b – the acquisition of plants, equipment, patents and other assets that may have a material impact on the issuer’s production capacity, if already disclosed There is no process for the acquisition of plants, equipment, patents or other relevant assets that could materially influence the Company's production capacity. 2.10.c – new products and services, indicating: 2.10.c (i) description of the ongoing research already disclosed; (ii) total amounts spent by the issuer on research for the development of new products or services; (iii) projects under development already disclosed; and (iv) total amounts spent by the issuer on the development of new products or services. Braskem's Innovation & Technology (R&T) area acts in line with the company's strategic direction, reflecting its vision of the future and commitment to the transformation of the chemical industry. The area has a global structure formed by 352 professionals distributed in research centers, laboratories and state-of-the-art pilot plants, dedicated to developing research that meets the needs of customers, being: (a) 2 technology and innovation centers located in Triunfo, Brazil, and Pittsburgh, United States; (b) 2 polymer technical centers located in Wesseling, Germany, and Coatzacoalcos, Mexico; (c) 1 process technology development center located in Mauá, Brazil; e (d) 2 research centers in renewable chemicals located in Campinas, Brazil, and Boston, United States. Based on this structure, projects and initiatives aligned with the objective were developed that sustain the perpetuity of the business through Braskem's Transformation Program, which brings in conjunction initiatives structured on three pillars: a. Naphtha-based optimization: comprises the implementation of the strategy for naphtha-based assets seeking greater profitability and cash generation. • In 2025, actions were initiated to transform the operation of the chlor-alkali plant, in Alagoas, into a dichloroethane volume handling unit ("EDC"), with the aim of increasing the competitiveness of PVC operations and making it more sustainable. As part of this process, chlor-alkali production was hibernated in September 2025 and part of the existing infrastructure was redirected to EDC handling logistics operations. b. Increase and flexibility of the gas base: considering the greater competitiveness of gas in relation to naphtha, the projects aim to (i) make feasible projects to increase the gas base capacity (ethane/propane/HLR); (ii) expansion of the flexibility of petrochemical plants in Brazil; and (iii) guarantee of operational stability, through stability in the supply and receipt of feedstock. • Part of this pillar is the Transforma Rio project, announced in February 2025, which aims to increase the capacity of the gas-based petrochemical plant in Rio de Janeiro by 220 thousand tons per year of ethylene and equivalent volumes of PE. On October 24, 2025, the approval of the investment by Braskem's Board of Directors was announced. The total estimated investment value is approximately R$ 4.2 billion, which may vary by up to 30% given the current stage of project maturity. The implementation of the Project, estimated to be completed by the end of 2028, is conditional on obtaining financing, in addition to the resources already approved under the REIQ Investimentos benefit for 2025 and 2026. It is estimated that approximately 80% of the project will be disbursed starting in 2027. c. Migration to products with renewable sources: the goal of expanding its production capacity to 1 million tons per year by 2030, reinforcing the competitive advantage in renewables. • Among the initiatives in progress, the following stand out: (i) the Sustainea joint venture, in partnership with Sojitz, which is studying the construction of plants for the production of MEG (monoethylene glycol) from renewable sources ("bioMEG") and MPG (monopropylene glycol) from renewable sources ("bioMPG"); (ii) the joint venture Braskem Siam, in partnership with SCG Chemicals, which evaluates the construction of the first green ethylene plant outside Brazil, in Thailand. In 2025, the Company maintained its focus on developing technological solutions that drive competitiveness, the continued satisfaction of its customers, sustainability and the transition to a circular and low-carbon economy. At the end of 2025, Braskem's portfolio had 108 projects in innovation and technology, more than 440 customers were supported by the team, and 35 new patent applications and 51 extensions were made. Starting in 2025, the Company adopted a new metric to more accurately reflect its strategic priorities and resource allocation. The indicator measures the overall percentage of innovation investments directed to projects with a positive impact on sustainability, such as bio-based initiatives and recycling technologies, considering the operating and capital expenditures ("CAPEX") directly associated with these projects. According to the defined methodology, 49% of innovation capital is currently focused on sustainable initiatives, with a goal of reaching 60% by 2030. In 2025, the total invested by Braskem's Innovation & Technology (R&T) area was R$404.8 million. 2.10.d – opportunities included in the issuer's business plan related to ESG issues: In 2024, Braskem defined the strategic direction with action fronts for the 2025–2027 cycle, based on three pillars: resilience and financial health, transformation and foundation, generating a positive impact for all stakeholders. The transformation pillar is guided by the Transformation Program, focusing on the transformation of Braskem's operations with the Switch to Gas and Fly up to Green strategy. This transformation aims to ensure greater resilience and profitability in the face of changes in the global petrochemical industry, while reinforcing the company's commitment to sustainable development and the agenda to combat climate change. The program is structured on three pillars: a. Naphtha-based optimization: comprises the implementation of the strategy for naphtha-based assets seeking greater profitability and cash generation. b. Increase and flexibility of the gas base: (i) feasibility of projects to increase the gas base capacity (ethane/propane/HLR); (ii) expansion of the flexibility of petrochemical plants in Brazil; and (iii) guarantee of operational stability, through stability in the supply and receipt of feedstock. c. Expansion of the portfolio of goods with renewable sources: the goal of expanding its production capacity to 1 million tons per year by 2030. Braskem has objectives aligned with sustainable development and a proven track record in implementing successful initiatives that reinforce sustainability and climate change mitigation. In line with the Company's Global Plan, Braskem sees the decarbonization of its assets as an opportunity related to ESG. In this sense, the Decarbonization Program was created, an industrial decarbonization plan with the objective of structuring the business plan and advancing initiatives that promote a 15% reduction in absolute CO2 equivalent emissions (scopes 1 and 2) by 2030. In 2025, Braskem continued to advance in the Decarbonization Program, strengthening its lines of action in continuous improvement, energy efficiency, electrification and transition of the energy matrix. Since the beginning of the program, more than 1.5 million tons of CO₂e have been reduced compared to baseline, considering the average from 2018 to 2020. The initiatives focus on Braskem's assets currently in operation and have as a methodological instrument the MACC – Marginal Carbon Abatement Curve and the Industrial Decarbonization Roadmap – Portfolio of Prioritized Decarbonization Initiatives. In line with the Migration to products with renewable sources, the Company continues to advance in its Joint Venture with SCG Chemicals, Braskem Siam Company Ltda, to enable the production of bioethylene in Thailand. The plant will be designed to have a capacity of 200 thousand tons, based on EtE Evergreen™ technology – its own technology, resulting from the partnership between Braskem and Lummus Technology. This initiative represents the Company's first industrial park in Asia and will contribute to the achievement of its long-term objectives. In 2025, the project advanced in the engineering detailing phase, a study necessary to obtain the cost and final design of the construction of the ethanol dehydration unit, for the production of bioethene. In addition, the project has made progress related to the agreements and supply of ethanol with local players, including the logistical solution for this supply and inclusion in the Free Trade Zone by the Thai customs department. In addition, in partnership with Sojitz (a company based in Japan), Sustainea was created, a joint venture focused on the production and commercialization of bioMEG, a feedstock used in the production of PET (polyethyl terephthalate), and bioMPG, which can be used in applications for civil construction, industrial use and cosmetics. In 2023, Sustainea produced the first bottle made from PET of renewable origin from the use of bioMEG, which passed regulatory tests for food contact. In 2025, the main milestones were strategic agreements that enabled access to proprietary processes for bioMEG production and specialized technical support throughout the project. BRASKEM S.A.

National Register of Legal Entities (CNPJ) No. 42.150.391/0001-70 State Registration (NIRE) 29300006939 A Publicly-Held Company ANNEX III MANAGEMENT PROPOSAL FOR THE ORDINARY GENERAL MEETING OF BRASKEM S.A. TO BE HELD ON APRIL 29, 2026 Proposal for the compensation of managers, pursuant to article 13, item I, of CVM Ruling 81 1. Proposal for the Compensation of Managers for 2026 Pursuant to the compensation strategy defined by the Board of Directors, with favorable recommendation from the Personnel and Organization Committee, the proposal of global compensation to the Company’s managers is based on the items below, with items (ii) and (iii) being applicable only to the Officers Appointed by the Bylaws: (i) The results of the study on executive compensation for the positioning of monthly fees and other compensation curves; (ii) The economic and financial indicators agreed upon for the year in order to define the sharing of results related to the short-term variable compensation; and (iii) Planning for the delivery of shares scheduled for 2026 within the scope of the Company’s 2026 Long-Term Incentive Plan. The total proposed amount for the global annual compensation of the administrators (Statutory Officers and members of the Company’s Board of Directors) for the 2026 fiscal year is up to R$ 84,307,940.81. This amount includes fixed and variable compensation, as well as applicable benefits, net of employer social charges, and represents a higher value than that approved at the Annual Shareholders’ Meeting held on April 28, 2025, as detailed throughout this Annex. The proposed global annual compensation also includes the remuneration of the regular and alternate members of the Board of Directors for their participation in advisory committees to the Board. The proposed global annual amount refers to an estimate of the maximum total sum that may be recognized by the Company in the 2026 fiscal year with respect to the compensation of its administrators, including fixed and variable components. The 8% increase in the global compensation amount for administrators compared to the value proposed for the 2025 shareholders’ meeting arises from the provision of a contingency fund to address potential consequences—regarding the Company’s management members—of a possible transaction involving the Company’s issued shares, as disclosed to the market through the Material Facts dated 12/15/2025, 12/23/2025, and 03/06/2026. Such consequences may include the possible creation of new positions within the Statutory Executive Board and new short- and long-term incentive programs or other compensation mechanisms intended to attract and/or retain executives in a highly complex scenario. The proposal is also based on aligning the compensation strategy for the Board of Directors and the Statutory Executive Board with market benchmarks. Additionally, Management proposes that the remuneration of the Fiscal Council members be set at the legal minimum amount, corresponding to 10% of the average compensation attributed to each director, pursuant to Article 162, §3, of the Brazilian Corporations Law, and up to the global amount of R$ 1,200,000.00. Summary of the main variations of the amounts of the proposals submitted to the Annual General Meeting in 2026 and 2025 Officers Board of Directors (BRL in thousands) Discrimination 2026 2025 Monthly and Short-Term Fees (ICP) 74,842 63,460 Long-Term Fees (ILP) 8,274 12,750 Benefits 1,191 1,790 Total (net of charges) 84,308 78,000 The amount related to the global compensation of the administrators proposed for the 2026 fiscal year is higher than the amount approved at the Annual Shareholders’ Meeting held on April 28, 2025. This increase results from the provision of a contingency fund to address potential consequences—regarding the Company’s management members—of a potential transaction involving the Company’s issued shares, as disclosed to the market through the Material Facts dated 12/15/2025, 12/23/2025, and 03/06/2026. Such consequences may include the possible creation of new positions within the Statutory Executive Board and the development of new short‑ and long‑term incentive programs or other compensation mechanisms aimed at attracting and/or retaining executives in a highly complex scenario. Notes: ¹ Alternate members of the Board of Directors are not entitled to compensation, except if they hold positions on advisory committees of the Board of Directors, and solely by reason of the function performed. This includes the compensation owed to both regular and alternate members of the Board of Directors for their participation in advisory committees to the Board of Directors. Fiscal Council (BRL in thousands) Discrimination 2025 2024 Fees 1,200 1,115 (Net) total 1,200 1,115 Notes: 1 The alternate members of the Fiscal Council receive no remuneration for their functions. 2. Amounts effectively realized in 2025 versus proposed amounts in 2025 Officers Board of Directors (BRL in thousands) Discrimination 2025 Proposal 2025 Realized Total 78,000 48,546 The amount actually realized in 2025 was lower than the amount proposed for the 2025 fiscal year, since the proposed annual global compensation for management for the 2025 fiscal year considered seven positions in the Statutory Executive Board, while the actual amount for annual global management compensation in the 2025 fiscal year reflects the five members of the Statutory Executive Board who served during 2025. Additionally, the use of the contingency fund projected for the fiscal year was not required.

National Register of Legal Entities (CNPJ) No. 42.150.391/0001-70 State Registration (NIRE) 29300006939 A Publicly-Held Company ANNEX IV MANAGEMENT PROPOSAL FOR THE ORDINARY GENERAL MEETING OF BRASKEM S.A. TO BE HELD ON APRIL 29, 2026 8. Compensation of managers 8.1. Describe the policy or practice adopted for compensation of the board of directors, Statutory Office and other officers, fiscal council, committees provided for in the bylaws and audit, risk, financial and compensation committees, addressing the following aspects: a. objectives of the compensation policy or practice, informing if the compensation policy was formally approved, the body responsible for its approval, approval date and, if the issuer discloses the policy, websites where the document can be found The Company adopts a competitive and transparent compensation strategy, which seeks to attract, develop and retain the best professionals and compensates its managers based on the market practices, according to their duties and responsibilities in effectively running the business. The variable compensation practice also allows strengthening the alignment of the shareholders’ interests with those of the Statutory Office in obtaining and exceeding the short- and long-term results. The Compensation Policy is formally approved by the Board of Directors. b. practices and procedures adopted by the board of directors to determine the individual compensation of the board of directors and the Management, indicating: (i) the bodies and committees of the issuer that are part of the decision-making process, identifying the manner in which they participate (ii) criteria and methodology used to set the individual compensation, indicating if studies were used to verify the market practices and, if so, the comparison criteria and scope of these studies (iii) frequency and how the board of directors evaluates the adequacy of the issuer’s compensation policy The proposals for Global Compensation of the Managers and the Fiscal Council are based on market studies, and are submitted to analysis by the Personnel and Organization Committee (“CPO”) of the Board of Directors prior to the submission to approval at an Annual General Meeting (“AGM”). After approval at the Annual General Meeting, the CPO recommends to the Board of Directors the proposal for individualization of the Compensation of the Managers, which is subsequently approved at a meeting of the Board of Directors. The proposal for individualization of the Compensation of the Managers is carried out as previously described in relation to the market comparison and strategic position of the members of the Board of Directors, as well as of the Statutory Officers. The frequency of the studies for updating and comparing the market occurs on an annual basis. c. breakdown of the compensation, stating: (i) a description of the elements that form the compensation, including, in relation to each of them: • their goals and alignment to short, medium, and long-term interests of the issuer • their proportion in the global compensation of the 3 last fiscal years • the calculation and adjustment methodology • the main performance indicators taken into account, including, if applicable, ESG-related indicators The objectives of the compensation elements, the calculation and adjustment methodology, as well as the main performance indicators (when applicable) are presented below: Board of Directors With the objective of compensating them for the duties and responsibilities inherent to the positions they hold, and in accordance with market practices, the regular members of the Board of Directors are remunerated competitively, with fixed fees (monthly pro‑labore payments) based on annual market surveys (through benchmarking against a peer group of companies of similar size and with sound policies and governance practices). Alternate members of the Board of Directors are not entitled to compensation for serving as alternates; they are only entitled to potential compensation arising from their participation in Committees, should they become members. Such compensation is also fixed and paid monthly. Additionally, both regular and alternate members are not entitled to variable compensation (short- or long‑term), nor to benefits for the exercise of their duties. This practice is reviewed annually by the CPO and the Board of Directors, and the total compensation amount proposed for the Board of Directors—including that corresponding to the participation of its members on Committees—forms part of the global compensation submitted for approval at the Annual Shareholders’ Meeting. The compensation strategy for the regular members of the Board of Directors is to position their fixed monthly fees competitively in relation to the practices of the relevant market. This strategy will always seek alignment with Braskem’s evolving governance. Board of Directors’ Advisory Committees For greater clarity regarding the objectives of the compensation elements and the calculation and adjustment methodology, we present below the Board of Directors' Advisory Committees and how they are organized: • Currently, the Company has one (1) committee appointed by the Bylaws, the Statutory Compliance and Audit Committee ("CCAE"), pursuant to CVM Ruling No. 23/21, the Sarbanes-Oxley Act and the rules issued by the Securities and Exchange Commission - SEC. The CCAE is a permanent advisory body of the Board of Directors, consisting of five (5) members, elected by the Board of Directors, of which three (3) are independent members of the Board of Directors in accordance with the Company's policies; and two (2) are members from outside the Company, as further detailed below. The two (2) members that are not part of the Board of Directors are chosen by the Board of Directors from the list submitted by the Chairman of the Board of Directors, prepared by a specialized company with proven experience, and appointment by the shareholders is not allowed. The Company also has three (3) other permanent Board of Directors’ Advisory Committees (not appointed by the Bylaws), namely: • Finance and Investment Committee; • Personnel and Organization Committee; and • Strategy & Communication Committee and ESG. Such committees not appointed by the Bylaws consist of the permanent and alternate members of the Company's Board of Directors, and the Chairman of the Board of Directors shall appoint the Board Members to compose each of the Committees and the designate the Coordinating Board Member, taking into account the experience and skills of each Board Member, vis a vis the attributions of each Committee. Each Committee will have at least three (3) and at most five (5) full members, with one member designated as the Coordinator. The terms of office of the Board Members in the Committees coincide with their terms on the Board of Directors, and re-election is permitted, provided that the members are reelected to their positions on the Board of Directors. With the objective of compensating them for the duties and responsibilities inherent to the positions they hold, and in accordance with market practices, the members of the Committees are remunerated competitively, with fixed fees (monthly pro‑labore payments) based on annual market surveys (through benchmarking against a peer group of companies of similar size and with sound policies and governance practices). The Company differentiates the monthly fees of Committee members according to the responsibilities and participation levels within each Committee, acknowledging and reflecting the time demands, responsibilities, and complexity inherent to the position held. Members of the CCAE who are not members of the Board of Directors will receive a fixed monthly compensation for serving on and/or coordinating a Committee. The differentiation of fees follows the same rule mentioned above. Regular and alternate members of the Board of Directors who serve on the Company’s Committees receive an additional fixed monthly fee for serving on and/or coordinating a Committee. No variable compensation (short- or long‑term) or benefits are granted to Committee members. This practice is reviewed annually by the CPO and the Board of Directors, and the compensation awarded to Committee members forms part of the total amount submitted for approval at the Annual Shareholders’ Meeting. The compensation strategy for the Board of Directors’ Advisory Committees is to position the fixed monthly fees competitively in relation to the practices of the relevant market. This strategy will always seek alignment with the evolution of Braskem’s governance model. Statutory Office and other Officers The members of the Statutory Office and other officers have a competitive compensation strategy, formed by the fixed monthly compensation, short- and long-term incentives and benefits. All compensation positioning takes into consideration the annual benchmark market in all locations where Braskem is present and compared to a peer group of companies, which have similar sizes and good practices regarding policies and governance: In the monthly compensation, the individual contribution and performance of each member of the Executive Office is assessed, its position in the compensation band and the need to make any adjustments to the monthly compensation is assessed; • In the variable compensation, the short-term incentive is proposed according to the challenge of each member and the individual performance is evaluated (through the fulfillment of individual goals) and Braskem's operational and economic performance (EBITDA + Free Cash Flow and Operating Cash Flow). The individual goals include ESG indicators such as, for example, investments in circular economy, marketing of recycled resins, CO2 emission reduction, action plans for the management of socio-environmental risks and implementation of action plans and other actions agreed with the Compliance department. Under the terms of the LTI Plans approved at the Company's Extraordinary General Meetings held on March 21, 2018 and July 28, 2023, the Board of Directors is responsible for annually approving its programs, the list of eligible people and the amount of shares to be delivered (matching in these programs, according to specific criteria provided for in the LTI Plan. In this sense, the members of the Company’s Office Appointed by the Bylaws and Other Offices are beneficiaries of the ongoing programs approved under the LTI Plan (2022, 2023 and 2024 Programs) and will receive the number of shares (matching) already defined by the Board of Directors for each of these programs. • The benefits offered by the Company to all officers are the same, such as: medical and dental assistance, meal vouchers, life insurance and private pension scheme. • The Company seeks to compensate its Officers in the 3rd quartile of the market, acknowledging and encouraging them to obtain and exceed the results to be achieved. The compensation of the Statutory Executive Board is reviewed annually by the CPO and the Board of Directors, and the total compensation amount proposed for the Executive Board forms part of the overall amount submitted for approval at the Annual Shareholders’ Meeting. With respect to the Non‑Statutory Executive Board, the approval of its compensation and any potential adjustments falls under the authority of LN‑Braskem.. Fiscal Council The permanent members of the Fiscal Council are compensated by means of fixed monthly fees, according to market research, meeting the minimum limit provided for in paragraph 3 of article 162 of the Brazilian Corporations Law, with the purpose of rewarding the board members for the attributions and responsibilities pertinent to the position held and in accordance with market practices and legal provision. The alternate members of the Fiscal Council receive no remuneration for their functions. There is no variable compensation (short or long term) and benefits for members of the Fiscal Council. The proportion of each element in the total compensation of each management body of the Company regarding the last three fiscal years is below: Thus, presented the details above, the alignment of the compensation elements to the interests of company occurs to the extent that they are (i) equitable (remunerate proportionately according to skills, professional training and impact on results); (ii) competitive (suitable to market standards); (iii) efficient (regarding the costs for the Company); and (iv) safe (committed to the continuity and growth of the business). The fulfillment of short, medium and long-term goals generates results for the company, thus adding value to it. In return, the Company distributes these results in the form of short- and long-term variable compensation. This cycle causes the Company to grow and develop to seek its perpetuity. The proportion of each element in the total compensation was as follows in the last 3 fiscal years: % in relation to the total compensation - 2025 Compensation Fixed Compensation Variable Benefits Total Board of Management 100% 0% 0% 100% Office Appointed by the Bylaws/Office Not Appointed by the Bylaws 31,20% 66,79% 2,01% 100% Fiscal Council 100% 0% 0% 100% Committees 100% 0% 0% 100% % in relation to the total compensation - 2024 Compensation Fixed Compensation Variable Benefits Total Board of Management 100% 0% 0% 100% Office Appointed by the Bylaws/Office Not Appointed by the Bylaws 27,72% 70,55% 1,72% 100% Fiscal Council 100% 0% 0% 100% Committees 100% 0% 0% 100% % in relation to the total compensation - 2023 Compensation Fixed Compensation Variable Benefits Total Board of Management 100% 0% 0% 100% Office Appointed by the Bylaws/Office Not Appointed by the Bylaws 45,6% 50,3% 4,1% 100% Fiscal Council 100% 0% 0% 100% Committees 100% 0% 0% 100% (ii) reasons that justify the composition of the compensation Board of Directors It is understood that the members of the Board of Directors must be entitled only to the fixed compensation in order to reflect the recognition given to their function that supervises and guides the Company Business, without, however, any involvement with its execution. Board of Directors’ Advisory Committees In the same way, it is understood that the Board of Directors’ Advisory Committees should be entitled only to fixed remuneration in recognition of their function, without, however, being involved with its execution. Statutory Office and other Officers The compensation of the Office Appointed by the Bylaws and Other Offices is in line with the market practices of the peer group (companies of equivalent size and with good practices in terms of policies and governance). The Company has a competitive practice regarding variable compensation, as it understands that this way, it aligns the interests of officers with those of the Company, sharing the risks and results of the Company with its main executives, seeking to obtain gains through the commitment to long-term results and short-term performance. Fiscal Council The composition of the compensation of the Fiscal Council is in line with market practices and with the provisions of paragraph 3 of article 162 of the Brazilian Corporations Law, which establishes the minimum legal compensation. (iii) existence of members not compensated by the issuer and the reason for such fact Alternate members of the Board of Directors and alternate members of the Fiscal Council do not receive fixed monthly fees, as they are not engaged in the Company’s activities. However, alternate members of the Board of Directors who serve on the Board’s Advisory Committees are compensated for that function. d. existence of compensation supported by subsidiaries, controlled companies or direct or indirect controlling companies There is no compensation for positions held in the Company that is funded by subsidiaries, controlled entities, or the Company’s direct or indirect controlling shareholders. e. existence of any compensation or benefit linked to the occurrence of a given corporate event, such as the disposal of corporate control of the issuer As a key personnel retention instrument, certain Statutory and Non-Statutory Directors are entitled to a “Retention Bonus”, the right to which is subject to certain conditions and requirements, linked to the occurrence of specific corporate events, including the change in control of the Company, as approved by the Board of Directors. In the event of a share transaction involving control of the Company during the year 2025, the new Statutory Directors sworn in in December 2024 will be entitled to payment of the full annual amount agreed for the short-term incentive for the year 2025. 8.2 Total compensation per body 9 Total compensation estimated for the current Fiscal Year ending on December 31, 2026 - Annual Amounts Board of Directors Statutory Office Fiscal Council Total Total number of members 11 8 5 24 No. of paid members 11 8 5 24 Fixed annual compensation Salary or Pro labore 9,847,200.00 15,578,883.87 1,200,000 24,199,204.96 Direct and indirect benefits 0.00 494,485.37 0.00 494,485.37 Participations in committees 3,684,000.00 0.00 0.00 3,684,000.00 Others 1,828,023.77 10,000,000.00 0,00 11,828,023.77 Description of other fixed compensations Contingency Contingency Contingency Variable compensation Bonus Profit sharing 24,155,000.00 24,155,000.00 Participation in meetings Commissions Others 8,501,250.00 8,501,250.00 Description of other variable compensations The members of the Board of Directors are not entitled to variable compensation.

Regarding the stock-based compensation plan of the board of directors and statutory officers in effect in the last fiscal year and expected for the current fiscal year, please describe: The company had two (2) plans with current grants, as detailed below: • The Company's Restricted Stock Grant Plan (“2018 Plan”) was approved at the Extraordinary General Meeting held on March 21, 2018, contemplating, among other members, the Officers Appointed by the Bylaws. The Plan was effective from the date of its approval by the Meeting and ended five (5) years after that date, in 2022. Within the scope of the Plan, however, the 2022 program was in effect until May 17, 2025, as detailed in items 8.9 and 8.10 below. • The Company's Restricted Stock Grant Plan (“2023 Plan”) was approved at the Extraordinary General Meeting held on July 28, 2023, contemplating, among other members, the Officers Appointed by the Bylaws. The Plan was effective from the date of its approval by the Meeting and ends five (5) years after that date, in 2028. The Plans can be found on the CVM website (www.cvm.gov.br) and on the Company's Investor Relations page (www.braskem-ri.com.br). The Company does not have an equity-based compensation plan for members of the Board of Directors. 2018 Plan (Effective from 2018 to 2022) a. general terms and conditions Natural persons who work for and are part of the Company or its controlled companies, including but not limited to Officers, may be nominated to participate in the Plan. The Board of Directors has defined, among such members, the participants of each annual restricted stock grant program (respectively "Eligible Persons" and "Program”). The Eligible Persons shall express their desire to adhere to the Plan and to the respective Program, upon the execution of the respective Award Agreement, then being referred to as “Participants”. The award of the Restricted Shares (“Consideration”) shall be conditioned to the voluntary investment of the Participants’ own funds to acquire owned shares (“Owned Shares”), and the Eligible Persons may voluntarily invest, with their own funds, the minimum amount of 10% and the maximum amount of 20% of the gross amount of their short-term planned incentive. The Plan's goal is to award, for every one (1) Owned Share, two (2) Restricted Shares. However, the Board of Directors may define, as an exception and with a justification, to each Program, a different multiple of Restricted Shares to be transferred to each Owned Share under the terms and conditions of the applicable Award Agreement, observing the minimum of one (01) Restricted Share and the maximum of three (3) Restricted Shares to each Owned Share. The number is defined at the exclusive discretion of the Board of Directors from the analysis of the following indicators: (a) the performance of the Company in the financial year immediately before the execution of the Award Agreement; (b) the expected challenge level to the Company in the three (03) years after the approval of each Program; and (c) the value of the Restricted Shares traded at B3 S.A. – Brasil, Bolsa, Balcão on the date of approval of each Program.
