AMBIPAR EMERGENCY RESPONSE

Notes to the Condensed Consolidated Financial Statements As of June 30, 2024, and December 31, 2023 (Values expressed in thousands of Brazilian Reais)

1.2.Authorization to issue these Consolidated Financial Statements

The issue of these Unaudited Condensed Consolidated Interim Financial Statements was authorized by the Management on August 8, 2024.

2.Description of significant accounting policies

2.1.Basis of presentation

As a result of the reorganization described below, these financial statements have been presented for all periods as if the Company was the holding company of the Group Response.

The Company became the holding company of the Group Response in June 2023 through a business combination (note 1.2) and as a result Emergência Participações S.A. (predecessor entity) became a wholly owned subsidiary of Ambipar Emergency Response.

These transactions are being accounted for on the predecessor values basis as common control transactions, based on the predecessor values recognized by the Company in its Unaudited Condensed Consolidated Interim Financial Statements from the dates that it obtained control of the Group Response.

Upon conclusion of the business combination, the results of operations of the Group were included in The Unaudited Condensed Consolidated Interim Financial Statements of the Company as if the Company had always owned the Group Response.

The Unaudited Condensed Consolidated Interim Financial Statements are expressed in thousands of Reais ("R$"), and the reporting of amounts in other currencies, when needed, is also expressed in thousands, unless otherwise indicated.

The preparation of The Unaudited Condensed Consolidated Interim Financial Statements requires Management to make judgments, use estimates and adopt assumptions that affect the amounts presented for revenues, expenses, assets and liabilities, including contingent liabilities. However, uncertainty relating to these judgments, assumptions and estimates could lead to results that require a significant adjustment to the book value of certain assets and liabilities in future years.

Ambipar Emergency Response’s Management states and confirms that all relevant information for The Unaudited Condensed Consolidated Interim Financial Statements is being evidenced and corresponds to the one used by Management in the administration.

The Unaudited Condensed Consolidated Interim Financial Statements have been prepared on the historical cost’s basis, except certain financial assets and liabilities that measured at their fair value.

The Ambipar Emergency Response’s businesses included in these Unaudited Condensed Consolidated Interim Financial Statements are not generated as a single legal entity. These Unaudited Condensed Consolidated Interim Financial Statements are, therefore, not necessarily indicative of performance, cash flows obtained, and possessing actual equity and financial situation, as if this Ambipar Emergency Response had operated in a single legal entity during the years, or indicative of future results.

The Unaudited Condensed Consolidated Interim Financial Statements have been prepared on a going concern basis, which assumes that the Ambipar Emergency Response will be able to discharge its liabilities.

2.2.Basis of consolidation

These Unaudited Condensed Consolidated Interim Financial Statements include the results of the Company and all its subsidiaries undertakings made up to the same accounting date. All intra-Group balances, transactions, income and expenses are eliminated in full on consolidation. The results of subsidiary undertakings acquired or disposed of during the period are included or excluded from the consolidated income statement from the effective date of acquisition or disposal.

2.3.New or revised pronouncements applied for the first time in 2024

The new IFRS standards will only be applied in Brazil after the issuance of the respective standards in Portuguese by the Accounting Pronouncements Committee and approval by the Federal Accounting Council.

a)Amendment to IFRS 17 Insurance Contracts;

IFRS 17 was issued by the IASB in 2017 and replaces IFRS 4 for the reporting period beginning on or after January 1, 2023.

IFRS 17 introduces an internationally consistent approach to the accounting of insurance contracts. Prior to IFRS 17, there was significant diversity around the world in relation to the accounting and disclosure of insurance contracts.

Given that IFRS 17 applies to all insurance contracts issued by an entity (with limited scope exclusions), its adoption may have an effect on non-insurers, such as the Company. The Company carried out an assessment of its contracts and operations and concluded that the adoption of IFRS 17 had no effect on its consolidated annual financial statements.

b)Amendment to IAS 1 Presentation of Financial Statements;

In February 2021, the IASB issued amendments to IAS 1, which aim to make accounting policy disclosures more informative by replacing the requirement to disclose "significant accounting practices" with "material accounting policies." The amendments also provide guidance on the circumstances in which accounting policy information is likely to be considered material and therefore require disclosure.

These changes have no effect on the measurement or presentation of any items in the Company's Unaudited Condensed Consolidated Interim Financial Statements but affect the disclosure of its accounting policies.

c)Amendment to IAS 12 Taxes on Profit;

i.Deferred Tax related to Assets and Liabilities arising from a Single Transaction.

In May 2021, the IASB issued amendments to IAS 12, clarifying the exemption from initial recognition for certain transactions that result in both an asset and a liability being recognized simultaneously (e.g. a lease under IFRS 16). The amendments clarify that the exemption does not apply to the initial recognition of an asset or liability that, at the time of the transaction, generates equal taxable and deductible temporary differences.

These changes had no effect on the Company's consolidated annual financial statements.

ii.International Tax Reform – Pillar Two Model Rules

In December 2021, the Organization for Economic Co-operation and Development (OECD) released a draft legislative framework for a global minimum tax that should be used by individual jurisdictions. The objective of the framework is to reduce the shifting of profits from one jurisdiction to another in order to reduce overall tax liabilities on corporate structures. In June 2022, the OECD released detailed technical guidance on the Pillar Two rules.

Stakeholders raised concerns with the IASB about the potential implications for income tax accounting, especially deferred tax accounting, arising from the Pillar Two model rules.

The IASB issued the final Amendments to the International Tax Reform – Pillar Two Model Rules, in response to stakeholder concerns on May 23, 2023.

The amendments introduce a mandatory exception for entities to recognize and disclose information on deferred tax assets and liabilities related to the Pillar Two rules. The exception takes effect immediately and retrospectively. The amendments also provide for additional disclosure requirements with respect to an entity's exposure to Pillar Two income tax.

Management has determined that the Company is not within the scope of the OECD's Pillar Two Model Rules and the exception to the recognition and disclosure of deferred tax information.

d)Change in IAS 8 Accounting Policies, Changes in Estimates and Rectification of Errors;

The amendments to IAS 8, which added the definition of accounting estimates, clarifies that the effects of a change in information or measurement technique are changes in accounting estimates, unless they result from the correction of errors from prior periods. These changes clarify how entities distinguish between changes in accounting estimates, changes in accounting policy, and errors from prior periods.

These changes had no effect on the Company's consolidated financial statements.

e)Amendments to IFRS 16

Add subsequent measurement requirements for sale and leaseback transactions, which satisfy the requirements of IFRS 15 - effective for periods beginning on or after January 1, 2024;

f)Changes to IAS 1

Clarifies aspects to be considered for the classification of liabilities as current and non-current - effective for periods starting on or after January 1, 2024;

g)Changes to IAS 1

Clarifies that only covenants to be fulfilled on or before the end of the reporting period, affect the entity's right to postpone the settlement of a liability for at least 12 months after the reporting date - effective for periods beginning on or after January 1, 2024;


						13


AMBIPAR EMERGENCY RESPONSE

Notes to the Condensed Consolidated Financial Statements As of June 30, 2024, and December 31, 2023 (Values expressed in thousands of Brazilian Reais)

h)Changes to IAS 7 and IFRS 7

Clarifies entity must disclose supplier financing arrangements, with information that allows users of the financial statements to assess the effects of these arrangements on the entity's liabilities and cash flows - effective for periods beginning on or after January 1, 2024.

2.4.New standards, revisions and interpretations issued that were not yet in force as of June 30, 2024

For the following rules or changes, management has not yet determined whether there will be significant impacts on the Company's financial statements, namely:

a)Amendments to IAS 21 - require the disclosure of information that allows users of the financial statements to understand the impact of a currency not being exchangeable - effective for periods beginning on or after January 1, 2025;

b)Issuance of the first sustainability disclosure standards by the International Sustainability Standards Board (ISSB), IFRS S1 and S2 – IFRS S1 establishes the main contents required for a complete set of financial disclosures related to sustainability and requires the entity to disclose information about all risks and opportunities related to sustainability, which can probably be expected and may affect the entity's prospects. This effect on the entity's prospects refers to its cash flow, its access to financing or cost of capital in the short, medium or long term. IFRS S2 requires an entity to report its exposure to climate-related risks and opportunities. Both S1 and S2 are in the process of translation and subsequent public consultation, by the Brazilian Committee of Sustainability Pronouncements (CBPS). It is expected that the appropriate final version of the standards for the Brazilian market will occur in 2024, since the CVM has already spoken out through CVM Resolution 59, encouraging companies to adopt the standards from 2025 or earlier, in order to voluntary, in 2024.

The Company is currently evaluating the impact of these new accounting standards and changes. The Company will assess the impact of the final amendments to IAS 1 on the classification of its liabilities as they are issued by the IASB. The Company does not believe that the amendments to IAS 1, in its current form, will have a significant impact on the classification of its liabilities, since the conversion feature on its convertible debt instruments is classified as an equity instrument and, therefore, does not affect the classification of its convertible debt as a non-current liability.

Other pronouncements and interpretations

There are no other rules, changes in rules and interpretations that are not in force that the Company and its subsidiaries expect to have a material impact resulting from their application in their individual and consolidated financial statements.

3.Basis of measurement

3.1.Currency translation

a)Functional and presentation currency

Items included in Ambipar Emergency Response’s Unaudited Condensed Consolidated Interim Financial Statements are measured using the currency of the primary economic environment in which companies operate ("the functional currency"). The Unaudited Condensed Consolidated Interim Financial Statements are presented in Reais (R$). All financial information disclosed has been rounded to the nearest value, except otherwise indicated.

b)Foreign currency

Transactions with foreign currencies are converted into functional currency by using exchange rates prevailing on the transaction or valuation dates when the items are measured. Exchange gains and losses resulting from the settlement of those transactions and from the translation at year-end exchange rates referring to monetary assets and liabilities in foreign currencies, are recognized in the statement of income. Foreign exchange gains and losses related to accounts receivable, suppliers and loans are presented in the statement of income as financial revenue or expense.

c)Foreign operations

The assets and liabilities of foreign operations, including goodwill and fair value adjustments arising on acquisition, are translated in euro at the exchange rates at the reporting date. The income and expenses of foreign operations are translated into euro at the exchange rates at the dates of the transactions.

Foreign currency differences are recognized in OCI and accumulated in the Translation reserve, except to the extent that the translation difference is allocated to NCI.

When a foreign operation in disposed of in its entirety or partially such as that the control, significant influence, or joint control is lost, the cumulative amount in the translation reserve related to that foreign operation in reclassified to profit or loss as part of the gain or loss on disposal. If the Company disposes part of its interest in a subsidiary but retains control, then the relevant proportion of the cumulative amount is reattributed to NCI. When the Company disposes only part of an associate or joint venture while retaining significant influence or joint control, the relevant proportion of the cumulative amount is reclassified to profit or loss.

3.2.Use of accounting estimates and judgment

The preparation of The Unaudited Condensed Consolidated Interim Financial Statements in accordance with International Financial Reporting Standards, issued by International Accounting Standards Board (IASB) and Interpretations (collectively "IFRS") and interpretations requires management to make judgments, estimates and assumptions that affect the application of accounting policies and the reported amounts of assets, liabilities, revenues, and expenses. Actual results may differ from these estimates. The settlement of transactions involving these estimates may result in significantly different amounts due to the lack of precision inherent to the process of their determination.


						15


AMBIPAR EMERGENCY RESPONSE

Notes to the Condensed Consolidated Financial Statements As of June 30, 2024, and December 31, 2023 (Values expressed in thousands of Brazilian Reais)

Estimates and assumptions are reviewed in a continuous manner. Revisions to accounting estimates are recognized in the year in which the estimates are revised and in any future periods affected. The information on critical judgments that refer to accounting policies adopted that have effects on amounts recognized in The Unaudited Condensed Consolidated Interim Financial Statements is presented in the following notes:

Impairment of non-financial assets

As stated in note 3.6, impairment testing involves calculating the value in use or the fair value less cost of disposal, when applicable, of the cash generating units to which the goodwill or other non-financial assets have been assigned. The value in use is determined by estimating five years of future cash flows, a perpetual value and using a discount rate that comprises three components: time value in money, the appropriate risk premium and uncertainty about the future cash flows. Hence, it relies on several critical judgements, estimates and assumptions. For more information on estimates and assumptions used in impairment testing, refer to note 8.

Revenue recognition

The Company applies certain judgment in assessing the terms of revenue from contracts with customers to determine whether the contract involves the delivery of service (revenue recognized over time). The Company evaluates each contract individually, its critical terms and business relationship with its customer and any associated third party.

Lease term

The Company determines the lease term as the non-cancellable term of the lease, together with any periods covered by an option to extend the lease if it is reasonably certain to be exercised, or any periods covered by an option to terminate the lease, if it is reasonably certain not to be exercised. The Company has the option, under some of its leases, to lease the assets for additional terms. The Company applies judgment in evaluating whether it is reasonably certain to exercise the option to renew, it considers all relevant factors that create an economic incentive for it to exercise the renewal such as contractual terms and conditions for the optional periods compared with market rates and the length of a non-cancellable period of a lease.

After the commencement date, the Company reassesses the lease term if there is a significant event or change in circumstances that is within its control and affects its ability to exercise (or not to exercise) the option to renew (e.g., a change in business strategy).

Residual value and estimated useful life of property, plant and equipment and intangible asset (finite useful lives)

As stated in note 3.5 and 3.7, Intangible and property, plant and equipment assets are amortized over their useful lives. The useful life is based on management’s estimates for the period in which the assets will contribute to generate revenue and is periodically reviewed. Changes in estimates may result in significant changes in the book value. Revisions to these estimates are recognized prospectively.

Business Combination Accounting

We recognize, separately from goodwill, the identifiable assets acquired, and liabilities assumed at their estimated acquisition date fair values. We measure and recognize goodwill as of the acquisition date as the excess of: (a) the aggregate of the fair value of consideration transferred, the fair value of any non-controlling interest in the acquiree (if applicable) and the acquisition date fair value of our previously held equity interest in the acquiree (if applicable), over (b) the fair value of net assets acquired, and liabilities assumed. At the acquisition date, we measure the fair values of all assets acquired and liabilities assumed that arise from contractual contingencies. We measure the fair values of all non-contractual contingencies if, as of the acquisition date, it is more likely than not that the contingency will give rise to an asset or liability.

Expected credit losses related to trade and other receivables

The expected loss on doubtful accounts is established when there is objective evidence that the Company will not be able to collect all amounts according to the accounts receivable original terms.

It is formed in an amount considered adequate by Management to cover probable losses arising on collection of accounts receivable, based on analysis of each client’s default risk considering a reasonable and supportable information available at the time that demonstrates that the credit risk has not increased significantly since initial recognition, the customer’s financial situation committed in the market, history of negotiations carried out, signed agreements not being fulfilled, mainly taking into consideration risk scenarios in which it has observable behavior in the market, and with special attention to long-standing overdue credits.

Income taxes

The calculation of current and deferred income taxes requires us to make estimates and assumptions and to exercise judgement regarding the carrying values of assets and liabilities which are subject to accounting estimates inherent in those balances, the interpretation of income tax legislation across various jurisdictions, expectations about future operating results, the timing of reversal of temporary differences and possible audits of income tax filings by the tax authorities.

Changes or differences in underlying estimates or assumptions may result in changes to the current or deferred income tax balances on the consolidated statements of financial position, a charge or credit to income tax expense in the Consolidated statements of operations and comprehensive income (loss) and may result in cash payments or receipts.

All income tax filings are subject to audits and reassessments. Changes in interpretations or judgements may result in a change in our income tax provisions in the future. The amount of such a change cannot be reasonably estimated.

3.3.Cash and cash equivalents

Cash and cash equivalents include cash, bank deposits, highly liquid short-term investments, redeemable in up to three months or less, with an insignificant risk of change in fair value and for the purpose of meeting short-term commitments.

3.4.Financial instruments

3.4.1.Financial assets

Recognition and measurement

Purchases and sales of financial assets are recognized on trading date, Investments are initially recognized at fair value plus transaction cost for all financial assets not classified at fair value recognized in income (loss).

Financial assets at fair value recognized in the income (loss) are initially recognized at fair value, and transaction costs are charged to statement of income in the period they occur.

The fair value of publicly quoted investments is based on the current purchase price. If the market of a financial asset is not active, the Ambipar Emergency Response establishes the fair value using valuation techniques. These techniques include the use of recent transactions contracted from third parties, reference to other instruments that are substantially similar, analysis of discounted cash flows and option pricing models, privileging market information and minimizing the use of information generated by Management.

Classification

In the initial recognition, a financial asset is classified as measured at: (i) amortized cost; (ii) fair value through other comprehensive income (“FVTOCI”); or (iii) fair value through profit or loss (“FVTPL”).

A financial asset is measured at amortized cost if it meets both conditions below: (i) the asset is held within a business model whose purpose is to collect contractual cash flows; and (ii) the contractual terms of financial assets give rise, on specific dates, to cash flows that are only payments of principal and interest on the outstanding principal value.

A financial asset is measured in FVOCI only if it meets both conditions below: (i) the asset is maintained within a business model whose purpose is achieved by both the collection of contractual cash flows and the sale of financial assets; and (ii) the contractual terms of financial assets give rise, on specific dates, to cash flows that refer to payments of principal and interest on the outstanding principal value. All other financial assets are classified as measured at fair value through profit or loss.

In addition, upon initial recognition, the Ambipar Emergency Response may, irrevocably, designate a financial asset that satisfies the requirements to be measured at amortized cost, FVTOCI or even FVTPL. This designation is intended to eliminate or significantly reduce a possible accounting mismatch stemming from the result produced by the respective asset.

Financial assets – Business model assessment

The Ambipar Emergency Response makes an assessment of the objective of the business model in which a financial asset is held at a portfolio level because this best reflects the way the business is managed, and information is provided to management. The information considered includes:

•the stated policies and objectives for the portfolio and the operation of those policies in practice. These include whether management’s strategy focuses on earning contractual interest income, maintaining a particular interest rate profile, matching the duration of the financial assets to the duration of any related liabilities or expected cash outflows or realizing cash flows through the sale of the assets;


						18


AMBIPAR EMERGENCY RESPONSE

Notes to the Condensed Consolidated Financial Statements As of June 30, 2024, and December 31, 2023 (Values expressed in thousands of Brazilian Reais)

•how the performance of the portfolio is evaluated and reported to the Ambipar Emergency Response’s management;

•the risks that affect the performance of the business model (and the financial assets held within that business model) and how those risks are managed;

•how managers of the business are compensated – e.g. whether compensation is based on the fair value of the assets managed or the contractual cash flows collected; and

•the frequency, volume and timing of sales of financial assets in prior periods, the reasons for such sales and expectations about future sales activity.

Transfers of financial assets to third parties in transactions that do not qualify for derecognition are not considered sales for this purpose, consistent with the Ambipar Emergency Response’s continuing recognition of the assets.

Financial assets that are held for trading or are managed and whose performance is evaluated on a fair value basis are measured at FVTPL.

Financial assets – Assessment whether contractual cash flows are solely payments of principal and interest

For the purposes of this assessment, ‘principal’ is defined as the fair value of the financial asset on initial recognition, ‘Interest’ is defined as consideration for the time value of money and for the credit risk associated with the principal amount outstanding during a particular period of time and for other basic lending risks and costs (e.g., liquidity risk and administrative costs), as well as a profit margin.

In assessing whether the contractual cash flows are solely payments of principal and interest, the Ambipar Emergency Response considers the contractual terms of the instrument. This includes assessing whether the financial asset contains a contractual term that could change the timing or amount of contractual cash flows such that it would not meet this condition, in making this assessment, the Ambipar Emergency Response considers:

•contingent events that would change the amount or timing of cash flows.

•terms that may adjust the contractual coupon rate, including variable‑rate features;

•prepayment and extension feature; and

•terms that limit the Ambipar Emergency Response’s claim to cash flows from specified assets (e.g., non‑recourse features).

A prepayment feature is consistent with the solely payments of principal and interest criterion if the prepayment amount substantially represents unpaid amounts of principal and interest on the principal amount outstanding, which may include reasonable compensation for early termination of the contract. Additionally, for a financial asset acquired at a discount or premium to its contractual per amount, a feature that permits or requires prepayment at an amount that substantially represents the contractual par amount plus accrued (but unpaid) contractual interest (which may also include reasonable compensation for early termination) is treated as consistent with this criterion if the fair value of the prepayment feature is insignificant at initial recognition.

Financial assets – Subsequent measurement and gains and losses


Financial assets at FVTPL						These assets are subsequently measured at fair value, Net gains and losses, including any interest or dividend income, are recognized in profit or loss.
Financial assets at amortized cost						These assets are subsequently measured at amortized cost using the effective interest method. The amortized cost is reduced by impairment losses, Interest income, foreign exchange gains and losses and impairment are recognized in profit or loss. Any gain or loss on derecognition is recognized in profit or loss.
Debt investments at FVOCI						These assets are subsequently measured at fair value, Interest income calculated using the effective interest method, foreign exchange gains and losses and impairment are recognized in profit or loss. Other net gains and losses are recognized in OCI. On derecognition, gains and losses accumulated in OCI are reclassified to profit or loss.
Equity investments at FVOCI						These assets are subsequently measured at fair value, Dividends are recognized as income in profit or loss unless the dividend clearly represents a investment’s cost part recovery. Other net gains and losses are recognized in OCI and are never reclassified to profit or loss.

Trade and other receivables

Trade and other receivables correspond to the amount’s receivable from clients for the rendering of service carried out in the normal course of Company’s activities. If the payment term is equivalent to one year or less (or any other term that is in conformity with Company's normal cycle), accounts receivable are classified as current assets. Otherwise, they are presented in non-current assets.

Trade and other receivables are initially recognized at fair value and, subsequently, measured at amortized cost using the effective interest rate method less expected impairment losses on accounts receivable, in practice, they are usually recognized at the billed amount, adjusted by provision for impairment, if necessary.

Recognition and derecognition

The financial instrument is recognized in The Unaudited Condensed Consolidated Interim Financial Statements when the entity becomes a party to the financial instrument contract. An entity removes a financial liability from its statement of financial position when its obligation is extinguished. An entity removes a financial asset from its statement of financial position when its contractual rights to the asset’s cash flows expire; when it has transferred the asset and substantially all the risks and rewards of ownership; or when it has transferred the asset and has retained some substantial risks and rewards of ownership, but the other party may sell the asset. The risks and rewards retained are recognized as assets.

Impairment of financial assets

Expected credit losses

The expected loss on doubtful accounts is established when there is objective evidence that the Company will not be able to collect all amounts according to the accounts receivable original terms.

AMBIPAR EMERGENCY RESPONSE

Notes to the Condensed Consolidated Financial Statements As of June 30, 2024, and December 31, 2023 (Values expressed in thousands of Brazilian Reais)

a)Recognition

The Ambipar Emergency Response recognizes loss allowances for Expected Credit Loss (ECLs) on:

•financial assets measured at amortized cost;

•debt investments measured at FVOCI; and

•contract assets.

The Ambipar Emergency Response also recognizes loss allowances for ECLs on lease receivables, which are disclosed as part of trade and other receivables.

The Ambipar Emergency Response measures loss allowances at an amount equal to lifetime ECLs, except for the following, which are measured at 12‑month ECLs:

•debt securities that are determined to have low credit risk at the reporting date; and

•other debt securities and bank balances for which credit risk (i.e. the risk of default occurring over the expected life of the financial instrument) has not increased significantly since initial recognition.

Loss allowances for trade receivables (including lease receivables) and contract assets are always measured at an amount equal to lifetime ECLs.

When determining whether the credit risk of a financial asset has increased significantly since initial recognition and when estimating ECLs, the Ambipar Emergency Response considers reasonable and supportable information that is relevant and available without undue cost or effort. This includes both quantitative and qualitative information and analysis, based on the Ambipar Emergency Response’s historical experience and informed credit assessment, that includes forward‑looking information.

The Ambipar Emergency Response assumes that the credit risk on a financial asset has increased significantly if it is more than 30 days past due.

The Ambipar Emergency Response considers a financial asset to be in default when:

•the debtor is unlikely to pay its credit obligations to the Ambipar Emergency Response in full, without recourse by the Ambipar Emergency Response to actions such as realizing security (if any is held); or

•the financial asset is more than 90 days past due.

The Ambipar Emergency Response considers a debt security to have low credit risk when its credit risk rating is equivalent to the globally understood definition of ‘investment grade’.

Lifetime ECLs are the ECLs that result from all possible default events over the expected life of a financial instrument.


						21


AMBIPAR EMERGENCY RESPONSE

Notes to the Condensed Consolidated Financial Statements As of June 30, 2024, and December 31, 2023 (Values expressed in thousands of Brazilian Reais)

12‑month ECLs are the portion of ECLs that result from default events that are possible within the 12 months after the reporting date (or a shorter period if the expected life of the instrument is less than 12 months).

The maximum period considered when estimating ECLs is the maximum contractual period over which the Ambipar Emergency Response is exposed to credit risk.

b)Measurement

ECLs are a probability‑weighted estimate of credit losses. Credit losses are measured as the present value of all cash shortfalls (i.e. the difference between the cash flows due to the entity in accordance with the contract and the cash flows that the Ambipar Emergency Response expects to receive).

ECLs are discounted at the effective interest rate of the financial asset.

c)Credit-impaired financial assets

At each reporting date, the Ambipar Emergency Response assesses whether financial assets carried at amortized cost and debt securities at FVOCI are credit‑impaired. A financial asset is ‘credit‑impaired’ when one or more events that have a detrimental impact on the estimated future cash flows of the financial asset have occurred.

Evidence that a financial asset is credit‑impaired includes the following observable data:

•significant financial difficulty of the debtor;

•a breach of contract such as a default or being more than 90 days past due;

•the restructuring of a loan or advance by the Ambipar Emergency Response on terms that the Ambipar Emergency Response would not consider otherwise;

•it is probable that the debtor will enter bankruptcy or other financial reorganization; or

•the disappearance of an active market for a security because of financial difficulties.

d)Presentation of allowance for ECL in the statement of financial position

Loss allowances for financial assets measured at amortized cost are deducted from the gross carrying amount of the assets.

For debt securities at FVOCI, the loss allowance is charged to profit or loss and is recognized in OCI.

e)Write-off

The gross carrying amount of a financial asset is written off when the Company has no reasonable expectations of recovering a financial asset in its entirety or a portion thereof. For individual customers, the Company has a policy of writing off the gross carrying amount when the financial asset is 180 days past due based on historical experience of recoveries of similar assets. For corporate customers, the Compnay individually makes an assessment with respect to the timing and amount of write‑off based on whether there is a reasonable expectation of recovery. The Company expects no significant recovery from the amount written off. However, financial assets that are written off could still be subject to enforcement activities in order to comply with the Company’s procedures for recovery of amounts due.


						22


AMBIPAR EMERGENCY RESPONSE

Notes to the Condensed Consolidated Financial Statements As of June 30, 2024, and December 31, 2023 (Values expressed in thousands of Brazilian Reais)

Derecognition of financial assets

A financial asset (or, when appropriate, part of a financial asset or part of a group of similar financial assets) is written off when: (i) the rights to receive cash flows from the asset have expired; and (ii) the Company transferred its rights to receive cash flows of the asset or has assumed an obligation to fully pay cash flows received, without significant delay, to a third party under terms of an "on lending" agreement; and (a) the Company has substantially transferred all risks and benefits related to the asset; or (b) the Company has not transferred and has not substantially retained all risks and benefits related to the asset, but has transferred control over that asset.

When the Company transfers its rights to receive cash flows from an asset or enters into a transfer agreement and does not transfer or substantially retain all risks and benefits related to the asset, an asset is recognized to the extent of the Company’s ongoing involvement with this asset.

3.4.2.Financial liabilities

Initial recognition, classification and measurement

A financial asset or financial liability is measured initially at fair value. Subsequent measurement depends on the category of financial instrument. Some categories are measured at amortized cost, and some at FVTPL. A financial liability is classified as at FVTPL if it is classified as held‑for‑trading, it is a derivative or it is designated as such on initial recognition. Financial liabilities at FVTPL are measured at fair value and net gains and losses, including any interest expense, are recognized in profit or loss. Other financial liabilities are subsequently measured at amortized cost using the effective interest method, Interest expense and foreign exchange gains and losses are recognized in profit or loss. Any gain or loss on derecognition is also recognized in profit or loss.

Interest rate benchmark reform

When the basis for determining the contractual cash flows of a financial asset or financial liability measured at amortized cost changed as a result of interest rate benchmark reform, the Company updated the effective interest rate of the financial asset or financial liability to reflect the change that is required by the reform. A change in the basis for determining the contractual cash flows is required by interest rate benchmark reform if the following conditions are met:

•the change is necessary as a direct consequence of the reform; and

•the new basis for determining the contractual cash flows is economically equivalent to the previous basis – i.e., the basis immediately before the change.

When changes were made to a financial asset or financial liability in addition to changes to the basis for determining the contractual cash flows required by interest rate benchmark reform, the Company first updated the effective interest rate of the financial asset or financial liability to reflect the change that is required by interest rate benchmark reform. After that, the Company applied the policies on accounting for modifications to the additional changes.

AMBIPAR EMERGENCY RESPONSE

Notes to the Condensed Consolidated Financial Statements As of June 30, 2024, and December 31, 2023 (Values expressed in thousands of Brazilian Reais)

Borrowing costs

Cost of loans attributed to the acquisition, construction or production of an asset that necessarily demands a substantial period of time to become ready for intended use or sale is capitalized as part of this asset’s cost.

Loan costs are comprised by interest and other costs that the Company incurs in connection with fundraising.

Derecognition of financial liabilities

A financial liability is derecognized when the obligation under the liability is discharged, canceled, or expired. When an existing financial liability is replaced by another of the same lender with substantially different terms, or the terms of an existing liability are significantly changed, this substitution or alteration is treated as a write-off of the original liability and recognition of a new liability, whereas the difference in the corresponding book value is recognized in the statement of income.

Loans and financing

Borrowings and financing are initially recognized at fair value, net of costs incurred in the transaction and are subsequently stated at amortized cost.

Any difference between the amounts raised (net of transaction costs) and the settlement amount is recognized in the income statement during the period while the loans are outstanding, under the effective interest rate method.

Loans and financing are classified as current liabilities unless the Company has an unconditional right to defer settlement of the liability for at least 12 months after the balance sheet date.

Warrant and Earn-out

Warrant is a financial instrument that confers the right, but not the obligation, to acquire shares at a specified price during a specific period. It is recognized as a financial liability, and the subsequent measurement of fair value is recognized in profit or loss for the period. The balance on June 30, 2024 is R$ 17,989.

Earn-out is related to the achievement of certain objectives in merger and acquisition operations, in which a part of the purchase price is deferred and based on the future performance of the company. It is recognized as a financial liability, and the subsequent measurement of fair value is recognized in the equity transaction account in the Company's equity.

Such operations are classified in IAS 32/IFRS 9 and are classified as derivative financial instruments, assets and liabilities. Fair value is calculated according to a Monte Carlo simulation model at each measurement date.

3.5.Intangible assets and Goodwill

(i)Software

Costs associated with maintaining software programs are recognized as an expense as incurred. Development costs that are directly attributable to the design and testing of identifiable and unique software products controlled by the Company are recognized as intangible assets where the following criteria are met:

•it is technically feasible to complete the software so that it will be available for use;

•management intends to complete the software and use or license it there is an ability to use or sell the software;


						24


AMBIPAR EMERGENCY RESPONSE

Notes to the Condensed Consolidated Financial Statements As of June 30, 2024, and December 31, 2023 (Values expressed in thousands of Brazilian Reais)

•it can be demonstrated how the software will generate probable future economic benefits;

•adequate technical, financial and other resources to complete the development and to use or sell the software are available; and

•the expenditure attributable to the software during its development can be reliably measured.

Directly attributable costs that are capitalized as part of the software include employee´s costs and an appropriate portion of relevant overheads.

Capitalized development costs are recorded as intangible assets and amortized from the point at which the asset is ready for use.

(ii)Goodwill

Goodwill is measured as described in note 9, Goodwill on acquisitions of subsidiaries is included in intangible assets, Goodwill is not amortized but it is tested for impairment annually, or more frequently if events or changes in circumstances indicate that it might be impaired and is carried at cost less accumulated impairment losses. Gains and losses on the disposal of an entity include the carrying amount of goodwill relating to the entity sold.

Goodwill is allocated to cash-generating units for the purpose of impairment testing. The allocation is made to those cash-generating units or groups of cash-generating units that are expected to benefit from the business combination in which the goodwill arose. The units or groups of units are identified at the lowest level at which goodwill is monitored for internal management purposes.

(iii)Research and development

Expenditure on research activities is recognized in profit or loss as incurred.

Development expenditure is capitalized only if the expenditure can be measured reliably, the product or process is technically and commercially feasible, future economic benefits are probable, and the Company intends to and has sufficient resources to complete development and to use or sell the asset. Otherwise, it is recognized in profit or loss as incurred. Subsequent to the initial recognition, development expenditure is measured at cost less accumulated amortization and any accumulated impairment losses.

(iv)Other Intangibles

Other intangible assets, including client’s portfolio, patents and trademarks, that are acquired by the Company and have finite useful lives are measured at cost less accumulated amortization and any accumulated impairment losses.

(v)Amortization

Amortization is recognized in the Consolidated Statement of Income (loss) based on the straight-line method in relation to the estimated useful lives, since this method is the closest that reflects the consumption pattern of future economic benefits incorporated into the asset. The estimated useful lives of intangible assets are as measured as described in note 9 (b).

The assets' net book values and useful lives are reviewed at each reporting date, and adjusted prospectively, where applicable.


						25


AMBIPAR EMERGENCY RESPONSE

Notes to the Condensed Consolidated Financial Statements As of June 30, 2024, and December 31, 2023 (Values expressed in thousands of Brazilian Reais)

In June 30, 2024, the Company reviewed the estimated useful lives of these assets, and no significant change was identified.

Other intangible assets, including customer relationships, work force, that are acquired by the Company and have finite useful lives are measured at cost less accumulated amortization and any accumulated impairment losses.

3.6.Impairment of non-financial assets

An impairment loss is recognized in The Unaudited Condensed Consolidated Interim Financial Statements of income (loss) for the amount by which the asset’s carrying amount exceeds its recoverable amount. The recoverable amount is the higher of an asset’s fair value less costs of disposal and value in use. For the purposes of assessing impairment, assets are grouped at the lowest levels for which there are separately identifiable cash inflows that are largely independent of the cash inflows from other assets or groups of assets (cash-generating units).

Goodwill and intangible assets that have an indefinite useful life are not subject to amortization and are tested annually for impairment, or more frequently if events or changes in circumstances indicate that they might be impaired. Other non-financial assets are tested for impairment whenever events or changes in circumstances indicate that the carrying amount may not be recoverable. Non-financial assets other than goodwill that suffered an impairment are reviewed for possible reversal of the impairment at the end of each reporting period. Therefore, impairment losses recognized for goodwill cannot be reversed in a subsequent period.

3.7.Property, plant, and equipment

Property, plant, and equipment (PPE) are stated at historical cost less accumulated depreciation and accumulates impairment losses (if applicable). Historical cost includes expenses directly attributable to the acquisition of items. Historical cost also includes financing costs related to the acquisition of qualifying assets.

Subsequently incurred costs are added to the asset's book value or are recognized as a separate asset, as applicable, and only when it is likely that associated future economic benefits will flow and that the item's cost can be reliably measured.

The book value of replaced items and parts is written off. All other maintenance and repair costs are recorded as a contra entry to income (loss) for the year, when incurred.

Lands are not depreciated. Depreciation of other assets is calculated using the straight-line method, with the costs of other assets being allocated to their residual values over the estimated useful life. Assets under development are not depreciated until they are available for use. Property, plant, and equipment useful lives are disclosed in note 8.

Residual values and the useful lives of material assets are reviewed and adjusted, if adequate, at the end of each year and depreciated using the straight-line method.

An asset's book value is immediately written down to its recoverable amount if the asset's book value is greater than its estimated recoverable amount, as impairment.


						26


AMBIPAR EMERGENCY RESPONSE

Notes to the Condensed Consolidated Financial Statements As of June 30, 2024, and December 31, 2023 (Values expressed in thousands of Brazilian Reais)

An item of property and equipment is de-recognized upon disposal or when no future economic benefits are expected to arise from the continued use of the asset. Any gain or loss arising on de-recognition of the asset (calculated as the difference between net disposal proceeds and the carrying amount of the asset) is included as a gain or loss in the Consolidated statement of operations in the period the asset is de-recognized.

Gains and losses from disposals are determined when the asset is derecognized by the comparison of results with the book value and are recognized in "Other net operating revenues (expense)" in the statement of income, as incurred.

3.8.Trade accounts payable and other accounts payable

Trade accounts payable and other accounts payable are obligations due for assets or services acquired from suppliers in the normal course of businesses and are classified as current liabilities if payment is due within one year. Otherwise, trade accounts payable are presented as non-current liabilities.

They are initially recognized at fair value and, subsequently, measured at amortized cost using the effective interest rate method. In practice, they are usually recognized at the amount of the related invoice.

3.9.Provisions

Provisions for lawsuits (labor, civil and tax) are recognized when: the Company has a present or constructive obligation as result of past events; it is likely that an outflow of funds will be required to settle the obligation; and if the amount can be estimated reliably, Provisions are not recognized for future operating losses.

When there is a series of similar obligations, the probability of settling them is determined by considering all obligation as a whole. A provision is recognized even if the likelihood of settlement related to any individual item included in the same class of obligations is small.

The provisions are measured at the present value of the expenditures that shall be necessary to settle the obligation, using a pre-tax rate which reflects the current market evaluations as to the value of the cash over time and the specific risks of the liability. The increase in the obligation over time is recognized as a financial expense.

3.10.Income tax

Income tax expense comprises current and deferred tax. It is recognized in profit or loss except to the extent that it relates to a business combination, or items recognized directly in equity or in OCI.

The Company has determined that interest and penalties related to income taxes, including uncertain tax treatments, do not meet the definition of income taxes, and therefore accounted for them under IAS 37 Provisions, Contingent Liabilities and Contingent Assets.

3.10.1.Current tax

Current tax comprises the expected tax payable or receivable on the taxable income or loss for the year and any adjustment to the tax payable or receivable in respect of previous years. The amount of current tax payable or receivable is the best estimate of the tax amount expected to be paid or received that reflects uncertainty related to income taxes, if any. It is measured using tax rates enacted or substantively enacted at the reporting date. Current tax also includes any tax arising from dividends.

Companies under the deemed income system

There are companies that opted for taxation based on estimated profit. The income tax and social contribution, both current and deferred, are calculated based on the rates of 15% plus a surcharge of 10% more than R$ 240 for income tax and 9% for social contribution, both applied to a percentage of 32% gross revenue.

Companies under the taxable income system

The income tax and social contribution of current year are calculated based on the rates of 15% plus a surcharge of 10% on taxable income more than R$ 240 for income tax and 9% on taxable income for social contribution on net income and take into account (if any) tax loss carry forward and negative basis of social contribution, limited to 30% of taxable income.

The Company operates in several international tax jurisdictions. Judgement is required in respect of the interpretation of state, federal and international tax law and practices as service provider and tax continues to evolve.

3.10.2.Deferred tax

Deferred tax is recognized in respect of temporary differences between the carrying amounts of assets and liabilities for financial reporting purposes and the amounts used for taxation purposes. Deferred tax is not recognized for:

•temporary differences on the initial recognition of assets or liabilities in a transaction that is not a business combination and that affects neither accounting nor taxable profit or loss;

•temporary differences related to investments in subsidiaries, associates and joint arrangements to the extent that the Company is able to control the timing of the reversal of the temporary differences and it is probable that they will not reverse in the foreseeable future;

•taxable temporary differences arising on the initial recognition of goodwill.

Temporary differences in relation to a right‑of‑use asset and a lease liability for a specific lease are regarded as a net package (the lease) for the purpose of recognizing deferred tax.

Deferred tax assets are recognized for unused tax losses, unused tax credits and deductible temporary differences to the extent that it is probable that future taxable profits will be available against which they can be used. There are no unrecognized tax losses or tax credits.

Future taxable profits are determined based on the reversal of relevant taxable temporary differences. If the amount of taxable temporary differences is insufficient to recognize a deferred tax asset in full, then future taxable profits, adjusted for reversals of existing temporary differences, are considered, based on the business plans for individual subsidiaries in the Company. Deferred tax assets are reviewed at each reporting date and are reduced to the extent that it is no longer probable that the related tax benefit will be realized; such reductions are reversed when the probability of future taxable profits improves.

The measurement of deferred tax reflects the tax consequences that would follow from the manner which the Company expects, at the reporting date, to recover or settle the carrying amount of its assets and liabilities. For this purpose, the carrying amount of investment property measured at fair value is presumed to be recovered through sale, and the Company has not rebutted this presumption.


						28


AMBIPAR EMERGENCY RESPONSE

Notes to the Condensed Consolidated Financial Statements As of June 30, 2024, and December 31, 2023 (Values expressed in thousands of Brazilian Reais)

Deferred tax liabilities are offset if a legally enforceable right exists to set off current income tax assets against current income tax liabilities and the deferred tax relates to the same taxable entity and the same taxation authority.

3.11.Revenue recognition

The revenue is stated net of taxes, returns, rebates or discounts, its recognition is in accordance with IFRS 15 - Revenue from customer contracts, which establishes a five-steps model to determine how and when it will be recognize, as well as its measurement, provided that revenues and costs can be measured reliably.

The Company revenue recognizes revenue when control of the promised services is transferred to the customer, in an amount that reflects the consideration the Company expects to be entitled to in exchange for those services.

In addition, specific criteria for each of the Company’s activities must be met, as described below:

Rendering of services

The Company provides emergency services that includes prevention, training, and emergency response.

Revenues are generated from services at customer sites or other locations. Response services for environmental emergencies include any scale from man-made disasters such as oil spills, to natural disasters such as hurricanes. Emergency response services are provided based on purchase orders or agreements with customers and include prices generally based upon daily, hourly or job rates for equipment, materials and personnel.

The Company recognizes revenue for these services over time, as the customer receives and consumes the benefits of the service as they are being performed and the Company has a right to receive for performance completed to date. The Company uses the input method to recognize revenue over time, based on time and materials incurred. The duration of such services can be over the number of hours, days or even months for larger scale projects. In this situation, can be recognized unbilled revenue.

3.12.Leases liabilities

As a lessee

At inception of a contract, the Company assesses whether a contract is, or contains, a lease liability. A contract is, or contains, a lease if the contract conveys the right to control the use of an identified asset for of the period agreed time in exchange for consideration.

At commencement or on modification of a contract that contains a lease component, the Company allocates the consideration in the contract to each lease component based on its relative stand‑alone prices. However, for the leases of property the Company has elected not to separate non‑lease components and account for the lease and non‑lease components as a single lease component.

The Company recognizes a right‑of‑use asset and a lease liability at the lease commencement date. The right‑of‑use asset is initially measured at cost, which comprises the initial amount of the lease liability adjusted for any lease payments made at or before the commencement date, plus any initial direct costs incurred and an estimate of costs to dismantle and remove the underlying asset or to restore the underlying asset or the site on which it is located, less any lease incentives received.


						29


AMBIPAR EMERGENCY RESPONSE

Notes to the Condensed Consolidated Financial Statements As of June 30, 2024, and December 31, 2023 (Values expressed in thousands of Brazilian Reais)

The right‑of‑use asset is subsequently depreciated using the straight‑line method from the commencement date to the end of the lease term, unless the lease transfers ownership of the underlying asset to the Company by the end of the lease term or the cost of the right‑of‑use asset reflects that the Company will exercise a purchase option. In that case the right‑of‑use asset will be depreciated over the useful life of the underlying asset, which is determined on the same basis as those of property and equipment. In addition, the right‑of‑use asset is periodically reduced by impairment losses, if any, and adjusted for certain remeasurements of the lease liability.

The lease liability is initially measured at the present value of the lease payments that are not paid at the commencement date, discounted using the interest rate implicit in the lease or, if that rate cannot be readily determined, the Company’s incremental borrowing rate. Generally, the Company uses its incremental borrowing rate as the discount rate.

The Company determines it’s the range incremental borrowing rate from 7,08% to 8,5% as each year by obtaining interest rates from various external financing sources and makes certain adjustments to reflect the terms of the lease and type of the asset leased.

Lease payments included in the measurement of the lease liability comprise the following:

•fixed payments, including in‑substance fixed payments;

•variable lease payments that depend on an index or a rate, initially measured using the index or rate as at the commencement date;

•amounts expected to be payable under a residual value guarantee; and

•the exercise price under a purchase option that the Company is reasonably certain to exercise, lease payments in an optional renewal period if the Company is reasonably certain to exercise an extension option, and penalties for early termination of a lease unless the Company is reasonably certain not to terminate early.

The lease liability is measured at amortized cost using the effective interest method. It is remeasured when there is a change in future lease payments arising from a change in an index or rate, if there is a change in the Company’s estimate of the amount expected to be payable under a residual value guarantee, if the Company changes its assessment of whether it will exercise a purchase, extension or termination option or if there is a revised in‑substance fixed lease payment.

When the lease liability is remeasured in this way, a corresponding adjustment is made to the carrying amount of the right‑of‑use asset or is recorded in profit or loss if the carrying amount of the right‑of‑use asset has been reduced to zero.

From January 1st, 2021, where the basis for determining future lease payments changes as required by interest rate benchmark reform, the Company remeasures the lease liability by discounting the revised lease payments using the revised discount rate that reflects the change to an alternative benchmark interest rate.

The Company presents right‑of‑use assets that do not meet the definition of investment property in ‘property, plant and equipment’ and lease liabilities in ‘loans and borrowings’ in the statement of financial position.

Short-term leases and leases of low-value assets

The Company has elected not to recognize right‑of‑use assets and lease liabilities for leases of low‑value assets and short‑term leases, including IT equipment. The Company recognizes the lease payments associated with these leases as an expense on a straight‑line basis over the lease term.

3.13.Distribution of dividends and interest on own capital

Payment of dividends and interest on capital to Company shareholders is recognized as a liability in The Unaudited Condensed Consolidated Interim Financial Statements at the end of the year, based on the by-laws that govern the Company’s companies.

Any amount above the mandatory minimum is provisioned only on the date of its approval by the shareholders.

The tax benefit of interest on own capital is recognized in the statement of income.

3.14.Business combinations

The Company accounts for business combinations using the acquisition method when the acquired set of activities and assets meets the definition of a business and control is transferred to the Company. In determining whether a particular set of activities and assets is a business, the Company assesses whether the set of assets and activities acquired includes, at least, an input and substantive process and whether the acquired set has the produce outputs ability.

The Company has an option to apply a ‘concentration test’ that permits a simplified assessment of whether an acquired set of activities and assets is not a business. The optional concentration test is met if substantially all the fair value of the gross assets acquired is concentrated in a single identifiable asset or group of similar identifiable assets.

The consideration transferred in the acquisition is generally measured at fair value, as are the identifiable net assets acquired. The goodwill constituted in the business combination is recorded in non-current assets, subgroup of intangible assets. Any goodwill that arises is recorded in intangible assets and tested annually for impairment. Any gain on a bargain purchase is recognized in profit or loss immediately. Transaction costs are expensed as incurred, except if related to the issue of debt or equity securities.

The consideration transferred does not include amounts related to the settlement of pre‑existing relationships. Such amounts are generally recognized in profit or loss.

Any contingent consideration is measured at fair value at the date of acquisition. If an obligation to pay contingent consideration that meets the definition of a financial instrument is classified as equity, then it is not remeasured, and settlement is accounted for within equity. Otherwise, other contingent consideration is remeasured at fair value at each reporting date and subsequent changes in the fair value of the contingent consideration are recognized in profit or loss.

If the Company makes a purchase of an investment and part of the amount is in installments, the accounts payable is recorded in the item Obligations from acquisition of, as mentioned in Note 7.

3.16.Segment reporting

For reviewing the operational performance of the Company and allocating resources purposes, the Chief Operating Decision Maker ("CODM") of the Company, which is comprised of the Chief Executive Officer of the Company, reviews the Consolidated results as a geographical area disaggregated by domestic market and foreign market as a whole market. The CODM considers the whole Company a single operating and reportable segment, when monitoring operations, making decisions on fund allocation, and evaluating performance. The CODM reviews relevant financial data on a Consolidated basis for all subsidiaries and business lines.

The Company’s net revenue, profit or loss, and assets and liabilities for this one reportable segment can be determined by reference to The Unaudited Condensed Consolidated Interim Financial Statements.

For more information regarding the Company's non-current assets and net revenue by geographic area, refer to note 8.

3.17.Earnings per share – basic and diluted

The Company calculates basic earnings per share using the total average weighted number of outstanding ordinary shares during the period corresponding to income, in accordance with accounting pronouncement IAS 33.

3.18.Prepaid expenses

Those are basically disbursements made in advance, which will be charged to the result as soon as the expenses are actually incurred.

3.19.Transactions eliminated on combination

Intra‑group balances and transactions, and any unrealized income and expenses (except for foreign currency transaction gains or losses) arising from intra‑group transactions, are eliminated. Unrealized gains arising from transactions with equity‑accounted investees are eliminated against the investment to the extent of the Company’s interest in the investee unrealized losses are eliminated in the same way as unrealized gains, but only to the extent that there is no evidence of impairment.

3.20.Financial income and financial expenses

The Company’s financial income and financial expenses include:

•interest income.

•interest expense.

•the net gain or loss on financial assets at FVTPL; and

•the fair value loss on contingent consideration classified as a financial liability.

The ‘effective interest rate’ is the rate that exactly discounts estimated future cash payments or receipts through the expected life of the financial instrument to:

•the gross carrying amount of the financial asset; or

•the amortized cost of the financial liability.


						33


AMBIPAR EMERGENCY RESPONSE

Notes to the Condensed Consolidated Financial Statements As of June 30, 2024, and December 31, 2023 (Values expressed in thousands of Brazilian Reais)

In calculating interest income and expense, the effective interest rate is applied to the gross carrying amount of the asset (when the asset is not credit‑impaired) or to the amortized cost of the liability. However, for financial assets that have become credit‑impaired after the initial recognition, interest income is calculated by applying the effective interest rate to the amortized cost of the financial asset, if the asset is no longer credit‑impaired, then the calculation of interest income reverts to the gross basis.

3.21.Share capital

Incremental costs directly attributable to the issue of ordinary shares are recognized as a deduction from equity, Income tax relating to transaction costs of an equity transaction is accounted for in accordance with IAS 12.

3.22.Financial risk management

The Company is party to transactions involving financial instruments for the purpose of financing its activities or investing its available funds.

The management of these risks is performed through the definition of conservative strategies aiming at liquidity, profitability, and safety. The control policy consists of permanent follow-up of the rates engaged versus those in force in the market.

In December 31, 2023, there were no transactions involving derivative financial instruments with speculative purposes and compound financial instruments with embedded derivatives.

Financial instruments are recognized only as from the date the Company becomes a party to contractual provisions. When recognized, they are initially recorded at its fair value plus any transaction costs directly attributed to its acquisition or issue (when applicable). Then they are measured at the end of each reporting period, in accordance with the standards established for each type of classification of financial assets and liabilities.

3.22.1.Financial risk factors

In the normal course of business, the Company is exposed to market risks, including changes in interest rates and foreign currency rates.

Market risk is the risk that changes in market prices – e.g. foreign exchange rates, interest rates and equity prices – will affect the Company’s income or the value of its holdings of financial instruments. The objective of market risk management is to manage and control market risk exposures within acceptable parameters, while optimizing the return.

The Company's activities expose it to various financial risks: market risk (including fair value interest rate risk, and cash flow interest rate risk and price risk), credit risk and liquidity risk, related primarily to our financing activities and foreign operation. The Company’s risk management program focuses on the unpredictability of financial markets and seeks to minimize potential adverse effects on the Company’s financial performance. The Company does not have operations quoted at commodity prices; therefore, it has no exposure to commodity price risks.

The management of risk is conducted by the treasure departments.

a)Market risk

Market risk is the risk that changes in market prices – e.g. Foreign exchange rate, interest rates and equity prices – will affect the Company’s income or the value of its holdings of financial instruments. The objective of market risk management is to manage and control market risk exposure within acceptable parameters, while optimizing the return.

(i)Interest rate risk

Interest rate risk arises from the portion of debt pegged to the long-term interest rate – CDI and interest earning bank deposits at CDI, which may affect the financial revenues or expenses in the event an unfavorable change in interest or inflation rates takes place. Loans issued at variable rates expose the Company to cash flow interest rate risk.

Loans issued at fixed rates expose the Company to fair value risk associated with interest rate. Considering that a substantial part of the Company’s loans is linked to fixed rates. Management believes that the risk of significant changes in income and cash flows is low.

The Company set three scenarios (probable, possible, and remote) for simulation, In the probable scenario, the rates disclosed by BM&F were set forth by the Management and the possible and remote scenario, a 25% and 50% impairment, respectively, in the variables. The calculation basis used is the amount presented in the notes of cash and cash equivalents, loans and financing and debentures:

•June 30, 2024 (unaudited)


	(Consolidated) scenarios
Index risk	Base	Probable	Possible	Remote
CDI - Interest earning bank deposits	321,859	33,795	42,244	50,693
CDI – Loans	(898,648)	(94,358)	(117,948)	(141,537)
CDI – Debentures	(252,803)	(26,544)	(33,180)	(39,816)
Net exposure	(829,592)	(87,107)	(108,884)	(130,660)

•December 31, 2023


	(Consolidated) scenarios
Index risk	Base	Probable	Possible	Remote
CDI - Interest earning bank deposits	132,072	15,518	19,398	23,277
CDI - Loans and Financing	(701,902)	(82,473)	(103,091)	(123,710)
CDI – Debentures	(545,750)	(64,126)	(80,158)	(96,189)
Net exposure	(1,115,580)	(131,081)	(163,851)	(196,622)

Due to the nature, complexity, and isolation of a single variable, the estimates presented may not faithfully represent the value of the loss, if the variable in question has the deterioration shown. The calculation was performed for a win/loss scenario in the period of one month.

b)Credit risk

Credit risk is the risk of financial loss to the Company if a customer or counterparty to a financial instrument fails to meet its contractual obligations and arises principally from the Company’s receivables from customers and investments in debt securities.


						35


AMBIPAR EMERGENCY RESPONSE

Notes to the Condensed Consolidated Financial Statements As of June 30, 2024, and December 31, 2023 (Values expressed in thousands of Brazilian Reais)

The credit risk arises from cash and cash equivalents, deposits in banks and other financial institutions, and exposure to client credit. For banks and financial institutions, only securities from entities considered as prime line are accepted.

The Credit Analysis area evaluates the client’s creditworthiness by considering their financial position, past experiences, and other factors.

Individual risk limits are determined with basis on internal or external classifications in accordance with limits determined by management. The use of credit limits is regularly monitored.

No credit limit was exceeded in the period, and Management does not expect any losses arising from defaults by those parties in addition to the provision already formed (Note 5).

As mentioned in note 18 - Segment reporting, the Emergency Response Services do not have customers representing more than 10% of their net revenue in June 30, 2024 and December 31, 2023.

c)Liquidity risk

Liquidity risk is the risk that the Company will encounter difficulty in meeting the obligations associated with its financial liabilities that are settled by delivering cash or another financial asset. The Company’s objective when managing liquidity is to ensure, as far as possible, that it will have sufficient liquidity to meet its liabilities when they are due, under both normal and stressed conditions, without incurring unacceptable losses or risking damage to the Company’s reputation.

The cash flow forecast is carried out by the Company’s Management. The Management monitors the continuous forecasts of Company’s liquidity requirements to ensure it has enough cash to satisfy operating needs. This forecast takes into consideration the Company’s debt financing plans, compliance with clauses, attainment of the internal goals of the balance sheet quotient and, if applicable, external or legal regulatory requirements - for example, currency restrictions.

Surplus cash held by the Company beyond the balance required for administration of working capital, is invested in checking accounts with incidence of interest, term deposits, short-term deposits, choosing instruments with appropriate maturities and sufficient liquidity to provide sufficient margin as determined by the above predictions. As of June 30, 2024, the Company maintained short-term funds of R$ 321,859 (R$ 143,473 as of December 31, 2023) which are expected to readily generate cash inflows to manage the liquidity risk.

d)Regulatory and environmental risks

The Company is subject to the laws and regulations of the countries where it operates. The Company’s Management established environmental certified policies and procedures focused on the compliance with environmental laws.

The Management carries out regular analyses to identify environmental risks and assure that controls under operation are appropriate and duly certified.

e)Foreign currency risks

On June 30, 2024, and December 31, 2023, the Company has not exposed to a significant transactional foreign currency. So, it concluded that they had no impact on the Annual Financial Statements as the fiscal years ends.

3.22.2.Capital management

The Company's objectives in managing its capital are to safeguard its business continuity capacity to offer return to shareholders and benefits to the other stakeholders besides maintaining an optimal capital structure to reduce this cost.

In order to keep or adjust the capital structure, the Company may review the dividend payment policy, refund capital to the shareholders or, also, issue new shares or sell assets to reduce, for instance, the indebtedness level.

The Company monitors capital based on the ratio of financial leverage. This index corresponds to net bank loans and financing divided by total capital. Net bank loans and financing, on its turn, corresponds to current and non-current loans and financings as shown in statement of financial position less cash and cash equivalents. Net bank loans and financing is a non-gaap measure.


						37


AMBIPAR EMERGENCY RESPONSE

Notes to the Condensed Consolidated Financial Statements As of June 30, 2024, and December 31, 2023 (Values expressed in thousands of Brazilian Reais)

The total capital is calculated through the sum of shareholders equity, as shown in the statement of financial position with net bank loans and financing and debentures.

The financial leverage ratio on June 30, 2024 and December 31, 2023, can be summarized as follows:


Consolidated financial information	June 30, 2024 (unaudited)	December 31, 2023
Loans and financing and debentures	1,151,451	1,247,652
Less: cash and cash equivalents	(549,513)	(423,266)
Net bank loans and financing	601,938	824,386
Total shareholders' equity	1,674,640	1,356,796
Total capital	2,276,578	2,181,182
Leverage ratio	26,4%	37.8	%

3.22.3.Fair value estimate

It is assumed that balances of trade accounts receivable and trade accounts payable at book value, less impairment loss, approximate their fair values, considering the realization terms and settlement of these balances, from 30 to 60 days.

For disclosure purposes, financial liabilities’ fair value is estimated by discounting future contract cash flows at interest rate prevailing in the market, which is available to the Company for similar financial instruments. The effective interest rates at the balance sheet dates are customary in the market and their fair values do not differ materially from the balances in the accounting records.

Interest earning bank deposits, represented by investments in Interbank Deposit Certificate (CDI) (note 4) were initially measured at fair value and classified as amortized cost. Additionally, were evaluated based on the yield rate contracted with the respective financial institution, considered as the usual market rate. Interest income from these financial assets is included in financial income using the effective interest rate method. Any gains or losses due to the write-down of the asset are recognized directly in profit (loss) and presented in net financial expenses.

Additionally, Management understands the financial instruments recognized in the financial information at their book values, do not show significant changes in relation to the respective market values.

Fair value is the amount for which an asset could be exchanged, or a liability settled, between knowledgeable and willing parties in arm's length transactions. Fair value hierarchy must have the following levels:

•Level 1: prices charged (unadjusted) in active markets for identical assets or liabilities;

•Level 2: different inputs of the prices negotiated in active markets included at Level 1 that are observable for the asset or liability, either directly (as prices) or indirectly (derived from prices); and

•Level 3: inputs for the asset or liability that are not based on observable market variables (non-observable inputs).

The expected credit losses are established by considering supportable information that is relevant and available without undue cost or effort. This includes both quantitative and qualitative information, based on the Ambipar Emergency Response’s historical experience and informed credit assessment, that includes forward‑looking information.

It is formed an amount considered adequate by Management to cover probable losses arising on collection of accounts receivable, based on analysis of each client’s default risk considering a reasonable and supportable information available at the time that demonstrates that the credit risk has not increased significantly since initial recognition, the customer’s financial situation committed in the market, history of negotiations carried out, signed agreements not being fulfilled, mainly taking into consideration risk scenarios in which it has observable behavior in the market, and with special attention to long-standing overdue credits.

The Company allocates each exposure to a credit risk grade based on the determined data to be predictive of the risk of loss (including but not limited to external ratings, audited Financial Statements, management accounts and cash flow projections and available press information about customers) and applying experienced credit judgement. Credit risk grades are defined using qualitative factors that are indicative of the risk of default and are aligned to external credit rating definitions from agencies.

Concerning the securities that are overdue for more than 181 days, the collection processes and procedures, and agreements, even in installment payments, are in progress, and the probability of success is relatively high.

The Company assumes that there was no significant decrease in ECL between December 2023 and June 2024, despite the relevant increase in accounts receivable. This situation is mainly due to the customer portfolio of new acquisitions without significant historical losses observed.

AMBIPAR EMERGENCY RESPONSE

Notes to the Condensed Consolidated Financial Statements As of June 30, 2024, and December 31, 2023 (Values expressed in thousands of Brazilian Reais)

For June 30, 2024 (unaudited), and June 30, 2023, the acquired companies contributed with the following net revenue and profit to the Company's results.


	June 30, 2024 (unaudited)		June 30, 2023
	Net Revenue	Profit for the year	Net Revenue	Profit for the year
Ambipar Response Marine S/A	—	—	5,681	2,393
Ambipar Response Industrial Services S/A	—	—	16,789	1,546
Ambipar Response Environmental Consulting Offshore	—	—	3,177	1,920
DFA Contracting Ltd	—	—	8,201	1,322

	—	—	33,848	7,181

(*) see note 7.6.

If the above acquisitions had occurred on January 1st, 2024, and January 1st, 2023, management estimates that the consolidated net revenue and profit for the year would have been the following:


	June 30, 2024 (unaudited)	June 30, 2023
Net Revenue	1,419,574	1,248,330
Profit for the period	122,393	(9,830)

Indetermining these amounts, management has assumed that the fair value adjustments, if any, determined provisionally, that arose on the date of acquisition would have been the same if the acquisition had occurred on January 1st, 2022. The information presented above is not intended to indicate expected results in future years, being only shown for informational purposes.

Goodwill

Management considered that most of the acquisitions performed by Response have a purpose of increasing market share and geographical presence. The response segment usually operates with emergency services, where being close to the customers is very important for a good performance of the services. Therefore, goodwill is measured as the excess of the cost of acquisition over the acquirer's fair value of assets, liabilities and contingent liabilities acquired.

Customer relationship

The Company considered that the customer relationships do not consist of relevant asset for the acquisitions because the acquiree did not present at the acquisition date contracts with customers that present a term long enough or large recurrence of services contracted by a customer that could present significant benefit to the acquirer. Most of the contracts with customers and relationship with customers refer to regional contracts with clients that are located on the geographical area of the acquiree. Aligned with the rationale presented on the section of “Brand” above, the acquirees mostly refers to small entities and have limited capabilities of retaining significant clients. The capability is improved by the acquiree from the moment that Response obtains its control, by applying the processes and skills of Ambipar Group.

Goodwill

The main motivation for the acquisitions of the Company refer to increase of market share on different geographical areas. All the acquisitions identified goodwill on the analyzed transactions. The Company understands that this amount goodwill presented above refers mostly to the expectation of benefits arising from the increase of market share that motivated the purchases.

Workforce

The Company did not identify an asset referring to workforce and work qualifications since the acquirees do not demonstrate competitive advantage on the market. The workers do not have proven specific training, needed for the rendering of the services provided by the acquirees. Also, the high turnover rates contribute for the non-significancy of the workforce on the acquisitions analyzed.

Brand

No asset related to brand was identified in the acquisitions since the acquirees do not disclose massively its brand name on the local media and market so it does not have expressiveness that could significantly contribute generating benefits related to this potential asset.

In addition, the Company has the practice of including the Ambipar Group’s brand to all the acquirees, in order to link the new acquiree to the Ambipar Group and help it to utilize the power of Ambipar’s brand and market recognition to help it improve the operations of the acquiree.

Obligation from acquisition

The payment schedule for obligations due to investment acquisition:


Year of maturity
2024						52,230
2025 (6 meses)						105,718
2025 (6 meses)						32,337
2026						36,044
2027						3,000
						229,329

Current						157,948
Non-current						71,381

Impairment tests

Goodwill is classified as an asset that has an undefined useful life and must be tested annually and whenever there are indications of possible loss of value. Assets and liabilities are grouped into a single CGU (Cash Generating Unit) which is the Group Response itself for the purpose of impairment testing, Goodwill was allocated to this single CGU.

Any impairment loss is immediately recorded as a loss in the statement of income and is not subject to a subsequent reversal.


						46


AMBIPAR EMERGENCY RESPONSE

Notes to the Condensed Consolidated Financial Statements As of June 30, 2024, and December 31, 2023 (Values expressed in thousands of Brazilian Reais)

The Company used the value-in-use method to carry out the impairment test. For the entire CGU, a 5-years projection period was considered, with growth in perpetuity, in addition to observing the financial budgets prepared by Management to start the projection of cash flows.

Cash flows were discounted to present value through the application of the rate determined by the Weighted Average Capital Cost (WACC), which was calculated using the Capital Asset Pricing Model (CAPM) method, also considering several components of financing, debt and equity used by the Company to finance its activities.

As a result of the impairment test, as of June 30, 2024 (unaudited), and December 31st, 2023, and evaluating the scenario that there have been no changes in significant risk variables and the used future cash flow assumptions of the acquired businesses since the last closing of the annual Consolidated Financial Statements, no losses have been identified for the CGU in which the goodwill is allocated.

The recoverable amounts of the CGUs at estimated value were its book value at the amount of R$ 2,954,031 (R$ 2,683,399 as of December 31, 2023). Management foresees that the two hypotheses of alteration are reasonably possible.

(c)Relevant maintenance costs

The Company owns an investment in a subsidiary of the aviation industry, which performs relevant maintenance on property, plant and equipment at regular intervals during its economic useful life. These maintenances are performed to restore or maintain the original performance standards foreseen by the suppliers and represent the only alternative for the use of the asset until the end of its useful life. For such maintenance, entities stop the operations of the asset or group of assets for a certain period of time and generally incur the following main expenses:

a)Main components and parts;

b)Own services or services contracted from third parties for the replacement of components and parts;

c)Own or outsourced services for relevant maintenance and cleaning; and

d)Fixed plant costs during the maintenance period, inventory losses, etc.

(d)PPE held as collateral

In the period ended on June 30, 2024 (unaudited), the amount of R$ 241,712 (R$ 141,821 as of December 31, 2023) is represented by the property, plant, and equipment in the vehicle classes (primarily represented by trucks), machinery, appliances, and equipment, which are the guarantees of the respective financing in the FINAME and Lease liabilities modality.

(e)Impairment

Management annually reviews the net book value of assets for purposes of evaluating events or changes in economic or operating circumstances that may indicate impairment or loss of its recoverable value. This evidence is detected and the net book value exceeds recoverable value, a provision for impairment is recognized to adjust net book value to the recoverable value.

The recoverable value of an asset is defined as the lower of its book value and its value in use. The value-in-use calculation is based on the discounted cash flow model, considering a single CGU that is the Group Response itself. The business growth assumptions are based on the annual budget for 2022 and the long-term projections of its subsidiaries. Estimated future cash flows were discounted at the rate equivalent to average weighted cost of capital. The fair value measurement was categorized as a Level 3 fair value based on the inputs in the valuation technique used.

The key assumptions used in the estimation of the recoverable amount are set out below. The values assigned to the key assumptions represent management’s assessment of future trends in the relevant industries and have been based on historical data from both external and internal sources.


In percent						%
Discount rate						20.19
Terminal value growth rate						3.4

The discount rate was a post‑tax measure estimated based on the historical industry average weighted‑average cost of capital.

Estimated EBITDA was projected considering histories and forecasts as follows:

•CGU’s revenues include service provision. Revenue growth was projected considering economic recovery and price increases/decreases based on inflation estimates;

•Operating costs and expenses were projected considering the historical performance of the CGU and the trends in personnel cost readjustments and investments in the structure; and

•Capital expenditures were estimated considering the maintenance of existing infrastructure, machinery, equipment, and vehicles for continuous operation and compliance with client contracts.

For June 30, 2024 (unaudited), and the year ended December 31, 2023, the estimated value in use exceeded the carrying amount.

(f)Leasehold improvements

Leasehold improvements comprise improvements made on third party properties and are substantially related to the lease liabilities agreement for the use of properties in Nova Odessa/SP and the Ambipar Group’s headquarters in São Paulo/SP with a related company of the Company, which owns the property, for a period of five years, signed in 2021.

Accounting impacts

a)Stock listing expense

The Transaction is not within the scope of IFRS 3 - Business Combination since HPX was a special purpose entity for the acquisition of businesses and did not meet the definition of business by the standard, thus being accounted for in accordance with the standard IFRS 2 – Share-Based Payment. According to this rule, AMBI recognized a single non-cash expense of R$ 100.9 million equivalents to US$ 19.4 million as a listing expense (Listing Expenses), based on the difference between the value of the AMBI shares issued to HPX shareholders and the fair value of HPX's identifiable net assets. This expense represents the implicit incurred cost of listing AMBI on the NYSE American.


			R$
Cost of shares issued to HPX shareholders (1)			146,741
Fair value of Earn-out shares for Ambipar Holding (2)			(44,240)
Adjusted cost of shares issued to HPX shareholders			102,501

HPX Assets			48,083
HPX Liabilities			(49,676)
HPX net assets on 3/3/2023			(1,593)

Stock listing expense			100,909

(2)Fair value estimated based on a Monte Carlo simulation model.

b)Transaction costs

The Company incurred extraordinary expenses of R$18,913 referring to legal, financial, and listing advisors.

c)Earn-out

As part of the Transaction, the Company is entitled to an additional 11,000,000 AMBI shares, to be issued in 2 tranches of 5,500,000 each in case certain objectives are achieved (“Earn-out”). The first tranche will be granted if the AMBI quotation exceeds US$17.0 per share during any 20 trading sessions out of 30 consecutive trading sessions. The second tranche will be granted if the AMBI quotation exceeds US$20.0 per share during any 20 trading sessions out of 30 consecutive trading sessions. If these objectives are not achieved by March 3, 2026, the Earn-out not awarded will be cancelled.

Earn-out is within the scope of IAS 32/IFRS 9 and was classified as a passive derivative financial instrument of AMBI. The subsequent measurement of fair value has been recognized in the equity transaction account in the Company's shareholders' equity. Earn out fair value is calculated according to a Monte Carlo simulation model at each measurement date, using typical inputs equity markets volatility, the price of AMBI shares and time to expiration. As the pricing inputs vary quarterly, so does the earn out fair value Company reorganization.

In 2021, the Company did a reorganization and had 100% of the capital stock of which held the control of investees: Ambipar Holding USA, Ambipar Holding Canada, Ambipar Holding UK, Ambipar Holding Ireland and Inversiones Disal which were part of the group and resulted in an impact of $326,056 in the Company's equity.
