Interim consolidated

and report on review

Report on review of interim

consolidated financial statements

To the Board of Directors and Shareholders

Ambev S.A.

Introduction

We have reviewed the accompanying interim consolidated balance sheet of Ambev S.A. and its subsidiaries ("Company") as at September 30, 2025, the related interim consolidated income statement and statement of comprehensive income for the quarter and nine-month periods then ended and the related interim consolidated statements of changes in equity and cash flows for the nine-month period then ended, and notes, comprising a summary of material accounting policies and other explanatory information.

Management is responsible for the preparation and fair presentation of these interim consolidated financial statements in accordance with the accounting standard International Accounting Standard (IAS) 34 - Interim Financial Reporting, of the International Accounting Standards Board (IASB). Our responsibility is to express a conclusion on these interim consolidated financial statements based on our review.

Scope of review

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

Conclusion

Based on our review, nothing has come to our attention that causes us to believe that the accompanying interim consolidated financial statements referred to above are not prepared, in all material respects, in accordance with IAS 34.

São Paulo, October 29, 2025

1.3 Major corporate events in the three-month period ended September 30, 2025

1.3.1 Distribution of dividends

In a meeting held on July 30, 2025, the Board of Directors approved the distribution of dividends in the amount of R$0.1283 per share of the Company, based on the balances available in the extraordinary balance sheet dated as of June 30, 2025, of which the amount corresponding to the profit recorded in the period from January 1st to June 30, 2025 was allocated to the minimum mandatory dividends for the 2025 fiscal year, without income tax withholding, pursuant to applicable law. The aforementioned payment was made on October 06, 2025, considering the shareholding position of August 07, 2025, with respect to B3 S.A. - Brasil, Bolsa, Balcão, and August 11, 2025 with respect to the New York Stock Exchange - NYSE, without any monetary adjustment. Shares and ADRs was traded ex-dividends as from and including August 08, 2025.

1.3.2 Sale of subsidiary

On December 26, 2024, the Company's subsidiary, Cervecería Nacional Dominicana, S.A. ("CND"), and Koscab Holdings Limited ("Koscab") entered into an Share Purchase Agreement (“Agreement”) through which CND committed to transfer all the shares it holds in the holding company SLU Beverages LTD. ("SLU") to Koscab. SLU holds a controlling interest in Banks Holdings Limited, Saint Vincent Brewery Limited, Antigua Brewery Limited, and Dominica Brewery & Beverages Limited, all of which form part of the CAC reportable segment.

The transfer of the entire interest will be made in consideration of a minimum estimated amount of US$186 million, equivalent to R$989 million, payable in up to five tranches through 2028. The completion of the first two tranches took place on July 31, 2025, upon which CND transferred to Koscab 61.83% of its interest in SLU for a price of US$115 million, equivalent to R$612 million. As a result of this completion, the Group recognized the loss of control over SLU, ceasing its consolidation in the financial statements for the period ended September 30, 2025. The remaining portion of the investment has been classified under assets held for sale, in accordance with IFRS 5 – Non-current Assets Held for Sale and Discontinued Operations.

As of September 30, 2025, the gain related to the transaction amounted to R$884 million, which was recorded under non-recurring items. The recognized gain includes the full reclassification of the cumulative amount of foreign exchange differences related to SLU, previously recognized in other comprehensive income within equity, to profit or loss for the period, in accordance with IAS 21 – The Effects of Changes in Foreign Exchange Rates.

The interim consolidated financial statements at September 30, 2025 have been prepared using the going concern basis of accounting and are being presented in accordance with IAS 34 – Interim Financial Reporting as issued by the International Accounting Standards Board (“IASB®”).

The information does not meet all disclosure requirements for the presentation of full annual consolidated financial statements and are disclosed with relevant information and changes in the period, without the level of detail in certain notes previously disclosed, avoiding repetition. In Management's view the interim consolidated financial statements provide sufficient understanding of the Company's equity position and performance during the interim period. Therefore, it should be read in conjunction with the consolidated financial statements for the year ended December 31, 2024, prepared in accordance with International Financial Reporting Standards (“IFRS®”) issued by the IASB®.

The following notes are not disclosed in the interim consolidated financial statements:

In addition, the material accounting policies presented in the respective accompanying notes are not disclosed in these interim consolidated financial statements. The following notes are not in the same level of detail presented in the annual consolidated financial statements, for the year ended December 31, 2024:

In preparing the interim consolidated financial statements, management uses judgments, estimates and assumptions that affect the application of accounting practices and the reported amounts of assets, liabilities, income and expenses. The relevant estimates and judgments are disclosed in note 4 - Use of estimates and judgments.

The interim consolidated financial statements relating to the period ended September 30, 2025 were approved by the Executive Board of Officers on October 29, 2025.

2.1 Functional and presentation currency

The functional and presentation currency of the Company interim consolidated financial statements is the Brazilian Real, which is the currency of its main economic operating environment. For presentation purposes, the interim consolidated financial statements are presented in thousands of Brazilian Reais (“R$”), unless otherwise indicated, and the balances are rounded to the nearest thousand.

2.1.1 Exchange rates

The most significant exchange rates used for the preparation of the Company’s interim consolidated financial statements are as follow:

The accounting practices adopted by the Company are consistent for all the years and periods presented. There were no changes to the accounting policies or calculation methods used for the interim consolidated financial statements at September 30, 2025 compared to those used for the consolidated financial statements for the years ended December 31, 2024.

3.1 Recently issued IFRS

The following new and amended standards that came into effect in 2025 were not applicable to or did not have any material impact on these consolidated financial statements:

The following are the main changes in accounting standards that, based on Management's assessment, may have an impact on the Company's disclosures in subsequent periods:

Beyond the above, the Company does not anticipate that any other standards or amendments to IFRS® standards or IFRIC® interpretations that have not yet come into force could have a material impact on the Group's financial statements. The Company has not opted for the early adoption of any standards.

The preparation of interim consolidated financial statements in compliance with IFRS requires Management to make use of judgments, estimates and assumptions that affect both the application of accounting practices and the reported amounts of assets and liabilities, income and expenses. The estimates and significant judgment are based on past experience and on other factors that are believed to be reasonable under the circumstances, the results of which form the basis for making judgments regarding the carrying amounts of assets and liabilities that cannot readily be determined based on other sources. The actual results achieved may differ from these estimates.

Such estimates and assumptions are reviewed on a regular basis. Changes in accounting estimates may affect the results for the period during which they are realized, or for future periods.

The impairment test is performed annually considering the most accurate estimates calculated by Management. The Company’s Management has not identified any relevant indications of impairment in the nine-month period ended September 30, 2025.

The accounting policy which reflects significant estimates and judgments used in the preparation of these interim consolidated financial statements for the nine-month period ended September 30, 2025 has not changed from those valid on December 31, 2024.

5.1 Cash and equivalents

(i) The balance refers mostly to Bank Deposit Certificates (“CDBs”), which have high liquidity, are readily convertible into known amounts of cash, and are subject to an insignificant risk of changes in value.

The cash and cash equivalents balance include the amount of R$5,314,017 at September 30, 2025 (R$8,038,817 in December 31, 2024), which is not freely remittable to the parent company due to remittance restrictions in Cuba and Argentina, and due to the unavailability of foreign currency in Bolivia, although the balances are available for use in the local operations of those subsidiaries.

5.2 Investment securities

(i) The balance refers substantially to financial investments linked to tax incentives that are not immediately convertible into a known amount of cash.

The changes in impairment losses on inventory are as follow:

(i) Effect related to the reclassification of SLU's asset balances to the line of assets held for sale, as note 1.3.2 – Sale of subsidiary.

(i) Over the past few years, as previously disclosed, the Company has recognized PIS/COFINS credits arising from the exclusion of ICMS, including in the form of tax substitution, from the calculation bases of these contributions. These tax credits were recorded against the recoverable taxes in the balance sheet, in the PIS/COFINS – ICMS exclusion line, as shown in the table above. The amounts that have not yet been offset substantially refer to tax credits from Regime Especial de Tributação de Bebidas Frias (“REFRI”), for the period from 2009 to 2015, in relation to which the lawsuit is currently in the final expert evaluation phase.

8.1 Deferred income tax and social contribution

The amounts of deferred income tax and social contribution for each type of temporary difference are as shown below:

(i) Historically, tax authorities have offset tax losses ex-officio in administrative proceedings in which the Company and some of its subsidiaries are involved, resulting in an accumulated offset of R$268,602. This amount is included in the tax credits recognized under the line of tax losses carried forward. As of September 30, 2025, the amount remained unchanged since there were no new ex-officio offsets during the period. The contingencies in question have a probability of a possible loss.

8.1.1 Realization of deferred taxes

At September 30, 2025, the deferred tax assets and liabilities expected to be utilized/settled, not related to tax losses, are: (i) to be realized until 12 months R$1,755,207; and (ii) to be realized after 12 months R$(706,477).

8.1.2 Net change in deferred taxes

The net change in deferred income tax and social contribution is as follows:

8.1.3 Deferred tax assets related to tax losses

Beyond the tax credits related to tax losses effectively recognized as part of the amounts disclosed above, there are other tax credits related to tax losses that were not recorded in the balance sheets due to their low expectations of realization, based on Management’s assessment. At September 30, 2025, the accumulated balance of these credits represented R$852,553 in taxable value (R$866,979 in December 31, 2024) equivalent to a taxable basis of R$3,242,247 in September 30, 2025 (R$3,310,110 in December 31, 2024).

8.2 Income tax and social contribution

The income taxes reported in the income statement are broken down as follows:

The reconciliation between the weighted nominal tax rate and the effective tax rate is summarized below:

The main events that impacted the effective tax rate for the period were:

9.1 Changes in the carrying amount of property, plant, and equipment

(i) Effect related to the reclassification of SLU's asset balances to the line of assets held for sale, as note 1.3.2 - Sale of subsidiary.

9.2 Changes in the carrying amount of right-of-use assets

(i) Effect related to the reclassification of SLU's asset balances to the line of assets held for sale, as note 1.3.2 - Sale of subsidiary. 

The present value adjustment related to the obligations recorded in trade payables, at September 30, 2025 is R$225,209 million (R$210,694 million at December 31, 2024).

The subsidiaries in Argentina, Chile, and Panama have discount transactions of endorsed trade bills (trade payables securitization) with vendors in the amount of R$35,941 million at September 30, 2025 (R$76,230 million at December 31, 2024). In general, such discount transactions occur due to legal requirements existing in these jurisdictions. These transactions retain their commercial characteristics, as there are no changes to the previously agreed conditions (amount, terms, or counterparty), and it is the vendor’s discretion to anticipate its receivables. Therefore, these transactions do not result in any additional obligations for the Company.

Additional information regarding the exposure of the Company to interest rates, foreign currency risk and debt repayment schedule is disclosed in Note 20 - Financial instruments and risks.

11.1 Contractual clauses (covenants)

At September 30, 2025, at December 31, 2024, and up to the date of issuance of these consolidated financial statements, no events of default, breaches of covenants, or significant contractual changes occurred that would result in changes to the payment terms of loan and financing agreements.

11.2 Leasing contracts regarding the term and discount rate (Brazil)

The Company estimated the discount rates based on the risk-free interest rates observable in the Brazilian market over the terms of its contracts, adjusted to its specific circumstances (i.e. the credit 'spreads'). These spreads are based on surveys conducted with financial institutions. The table below presents the weighted average rates applied, considering the terms of the existing contracts:

The Company and its subsidiaries are involved in administrative and judicial proceedings and arbitrations arising from the normal course of business. The assessment of the likelihood of loss, carried out by the Company with the support of its legal advisors, considers the likelihood of the Company position being accepted at the end of the proceedings, considering the applicable legislation, the case law on the subject and the existing evidence. Due to their nature, these proceedings involve inherent uncertainties, including, but not limited to, decisions by courts and tribunals agreements between the parties involved and governmental actions and, as a result, Management cannot, at this stage, estimate the precise timing to conclude such proceedings.

12.1 Provisions

The lawsuits considered probable of loss are fully provisioned, under the terms of IAS 37 - Provisions, Contingent Liabilities and Contingent Assets, and have a tax, civil or labor nature. Cases are considered likelihood of loss when there is established or binding case law unfavorable to the position defended by the Company and its subsidiaries, or, in the case of factual or evidentiary disputes, when the Company and its subsidiaries do not have the necessary and sufficient evidence to prove the claimed right.

12.1.1 Main lawsuits with a probable likelihood of loss

Taxes on sales: in Brazil, the Company and its subsidiaries are parties to various administrative and judicial proceedings related to ICMS, IPI, PIS and COFINS taxes, considered as probable likelihood of loss. Such proceedings include, among others, tax offsetting, appropriation of tax credits and alleged insufficient payment of the respective taxes.

Labor: the Company and its subsidiaries are parties to labor lawsuits considered likely to result in loss, involving former employees, including those from outsourced service providers. The main issues involve overtime and related effects and respective charges.

Civil: the Company and its subsidiaries are involved in civil proceedings considered as representing a probable likelihood of loss. The most relevant portion of these lawsuits was filed by former distributors, mainly in Brazil, mostly claiming damages resulting from the termination of their contracts with the Company.

Other taxes: refer to provisions for lawsuits concerning taxes unrelated to sales or income taxation. The uncertain tax treatments related to income taxes with a prognosis of probable loss have their value reported directly in the income tax and social contribution payable line, as per IFRIC 23 - Uncertainty on the Treatment of Income Taxes.

12.1.2 Provisions changes

12.1.3 Expected settlement of provisions

The expected settlement of provisions was based on Management’s best estimate, in line with their internal and external legal advisors’ assessments, at the consolidated balance sheet date.

12.2 Contingencies

The Company and its subsidiaries maintain administrative and judicial disputes with fiscal authorities in Brazil related to certain tax positions adopted when calculating the income tax and social contribution, which, based on Management’s current evaluation, probably are going to be accepted in superior court decisions of last instance, considering the regular compliance with tax laws, case law, and evidence produced, in line with IFRIC 23 - Uncertainty over Income Tax Treatments. The Group is also part on tax proceedings related to other taxes, which involve possible loss risk, according to Management's assessment. To these uncertain tax treatments and possible contingencies there are no constituted provision, due to the prognosis assessment carried out. Such proceedings represent the following estimates.

Contingencies with a remote risk of loss are not disclosed, as the possibility of any settlement is remote, in accordance with IAS 37 - Provisions, Contingent Liabilities and Contingent Assets.

The Company and its subsidiaries have guarantee-insurance bonds and letters of guarantee for some legal proceedings, presented as guarantees on civil, labor and tax lawsuits.

12.2.1 Main contingencies with a possible risk of loss

The changes in the amount of contingencies reported relate mainly to the increase resulting from monetary restatement. In addition, the main process classified with a possible loss probability, which relevant changed until September 30, 2025, are summarized in the table below, along with their respective estimated values involved in the cases.

12.2.2 Tax Proceeding Initiated by the Group

The Company is also a party on other tax proceedings in which it is the plaintiff and discusses the possibility of recovering or avoiding the payment of taxes that, in the Administration's view, lack constitutional and/or legal support for their enforcement. As disclosed on the accounting policy, the Company does not recognize contingent assets in its financial statements. If the inflow of economic benefits becomes probable, based on a forecast assessment conducted by external legal advisors in conjunction with the internal assessment of the Administration, the Company discloses the contingent asset. When the inflow of economic benefits becomes virtually certain, such as when a final judgment is rendered in the case and the gain can be reliably estimated, the asset is no longer contingent, and the Company recognizes it in the financial statements in period in which the estimate has changes.

The contingent assets with relevant changed until September 30, 2025, are summarized in the table below.

13.1 Issued capital

At September 30, 2025, the authorized and issued capital, fully subscribed and paid in, amounting to R$58,275,696 (R$58,226,036 in September 30, 2024) was composed of 15,761,639 common shares (15,757,657 in September 30, 2024), book entry, registered, and with no par value, distributed as follows:

(i) Capital increase related to the issue of shares, under Company’s share-based payment programs.

13.2 Capital reserves

13.2.1 Share buyback and treasury shares results

Treasury shares represent the Company’s own issued shares that have been repurchased by the Company. The results of treasury shares refer to gains and losses arising from share-based payment transactions and others related items. The changes in treasury shares are as follow:

13.2.2 Share-based payment

Different share-based payment programs allow the Group’s senior management to acquire shares in the Company (Note 19 – Share-based payments). The share-based payment reserve recorded an expense of R$306,106 on September 30, 2025 (R$290,447 at September 30, 2024).

13.3 Net income reserves

There was no change in profit reserves in the third quarter of 2024 and of 2025.

13.3.1 Tax incentives

The tax incentives recognized by the Company in its net equity, under profit reserves, relate to industrial development programs that aim at the fostering of employment generation, increasing of regional decentralization, in addition to complementing and diversifying the industrial bases of some regions and states in Brazil. In these states, the grace periods and incentive terms are set out in normative acts issued by the respective states, and when there are conditions for obtaining these grants, they are under the Company’s control. The tax treatment of states incentives complies with the provisions of current federal, state, and municipal legislation, particularly Complementary Federal Law No. 160/2017 and CONFAZ Agreement No. 190/2017. Following the revocation of Article 30 of Federal Law No. 12,973/14 by Federal Law No. 14,789/23, the state tax incentives in the form of presumed ICMS credits have ceased to be allocated to the tax incentive reserve, starting from 2024. The other federal and state tax incentives continue to be recognized as reserve.

13.3.2 Interest on capital/dividends
