Any deterioration of those relations or increase in labor costs due to our compliance with labor laws could adversely affect our business.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Our market is highly competitive. Failure to compete successfully could have a material adverse effect on our business, financial condition and results of operations.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• The dual class structure of our Ordinary Shares may adversely affect the trading market for our Class A Ordinary Shares.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• We may redeem unexpired Warrants prior to their exercise at a time that is disadvantageous to warrantholders, thereby making their Warrants worthless.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Our management has the ability to require holders of our Warrants to exercise such Warrants on a cashless basis which would cause holders to receive fewer ordinary shares upon their exercise of the Warrants than they would have received had they been able to exercise their Warrants for cash.

**Financial Statement Presentation**

***The Company***

The Company was incorporated by Ambipar under the laws of the Cayman Islands on May 3, 2022 for the purpose of effectuating the Business Combination.

On March 3, 2023 (the "Closing Date"), Ambipar Emergency Response, an exempted company incorporated with limited liability in the Cayman Islands (the "Company"), consummated the previously announced business combination (the "Closing") pursuant to the Business Combination Agreement, dated as of July 5, 2022 (the "Business Combination Agreement"), by and among the Company, HPX Corp., a Cayman Island exempted company ("HPX"), Ambipar Merger Sub, an exempted company incorporated with limited liability in the Cayman Islands and a wholly-owned subsidiary of the Company ("Merger Sub"), Emergência Participações S.A., a *sociedade anônima* organized under the laws of Brazil ("Emergencia"), and Ambipar Participações e Empreendimentos S.A., a *sociedade anônima* organized under the laws of Brazil ("Ambipar").

Prior to the Business Combination, the Company had no material assets and did not operate any businesses. The Business Combination resulted in (i) the merger of the blank check company, HPX, with and into the Company, with a conversion of the shares and warrants issued by HPX into those of the Company, and immediately thereafter, (ii) the merger of Merger Sub with and into the Company, with a conversion of the shares issued by Merger Sub into those of the Company. The Business Combination was unanimously approved by HPX's board of directors and was approved at the extraordinary general meeting of HPX's shareholders held on February 28, 2023 (the "HPX Extraordinary General Meeting"), and on March 6, 2023, our Class A Ordinary Shares and our Warrants commenced trading on the NYSE American LLC ("NYSE American") under the symbols "AMBI" and "AMBIWS," respectively. Following the Business Combination, Emergencia became a wholly-owned subsidiary of the Company.

HPX did not meet the definition of a "business" pursuant to IFRS 3 as it was an empty listed shell holding only cash raised as part of its original equity issuance. As a result, the Business Combination did not qualify as a "business combination" within the meaning of IFRS 3, Business Combinations; rather, the Business Combination was accounted for as a capital reorganization in accordance with IFRS 2, Share-Based Payments.

As a result of the Business Combination being accounted for as a capital reorganization, Emergencia was deemed to be the accounting predecessor of the Company. The accounting predecessor has a direct voting interest or a variable interest in all of our direct and indirect subsidiaries' activities and operations that result in revenues, expenses, assets and liabilities.

We maintain our books and records in Brazilian *reais*, the functional currency of our operations and the presentation currency for our audited Consolidated Financial Statements. Unless otherwise noted, the financial information presented herein has been derived from our audited Consolidated Financial Statements as of December 31, 2024 and 2023 and for each of the three years ended December 31, 2024, 2023 and 2022 together with the accompanying notes thereto, prepared in accordance with IFRS and included elsewhere in this annual report, or our audited Consolidated Financial Statements.

Certain amounts and percentages included in this annual report have been rounded for ease of presentation. Percentage figures included in this annual report have not been calculated in all cases on the basis of the rounded figures but on the basis of the original amounts prior to rounding. For this reason, certain percentage amounts in this annual report may vary from those obtained by performing the same calculations using the figures in our audited Consolidated Financial Statements. The tables included in this annual report may not total due to rounding.

**Important Information About GAAP and Non-GAAP Financial Measures**

To evaluate the performance of our business, our management relies on both our results of operations recorded in accordance with IFRS and certain non-GAAP financial measures, including EBITDA, EBITDA Margin, ROIC, Free Cash Flow and Cash Conversion Rate. Management believes that these measures provide investors with a supplemental measure of the operating performance and financial results of our core operations that facilitates period-to-period comparisons on a consistent basis. These measures are not defined or calculated under principles, standards or rules that comprise IFRS or U.S. GAAP and have important limitations as analytical tools. Accordingly, the non-GAAP financial measures we use and refer to should not be viewed as a substitute for our audited Consolidated Financial Statements prepared and presented in accordance with IFRS or any other performance measure derived in accordance with IFRS, and we encourage you not to rely on any single financial measure to evaluate our business, financial condition or results of operations.

Our definition of EBITDA, EBITDA Margin, ROIC, Free Cash Flow and Cash Conversion Rate are specific to our business and you should not assume that these definitions are comparable to similarly titled financial measures of other companies. These financial measures should be viewed as supplemental to, and not substitutive for, our audited Consolidated Financial Statements included elsewhere in this annual report. Because this financial information is not prepared in accordance with IFRS, you are cautioned not to place undue reliance on this information.

For a reconciliation of these non-GAAP measures to the most directly comparable IFRS measures, see *"Item 5.A. Operating and Financial Review and Prospect—Operating Results—Non-GAAP Financial Measures—Reconciliation of Non-GAAP Financial Measures."*

***EBITDA and EBITDA Margin***

We calculate EBITDA as profit (loss) for the year plus income tax and social contribution plus net finance cost/revenue plus depreciation and amortization expenses, in each case for the relevant year.

Management believes that EBITDA is a useful indicator of our operating performance because it evidences the results deriving directly from our core activities and improves comparability with our performance over time. Also, management believes that EBITDA is a useful indicator of our capacity to comply with our obligations and obtain financing for our investments and working capital.

We calculate EBITDA Margin as EBITDA for the relevant year divided by net revenue for the relevant year. Management believes that EBITDA Margin is a useful indicator of the performance of our core activities, in relative terms.

Although EBITDA and EBITDA Margin are commonly used as a measure of operating performance, definitions of EBITDA and EBITDA Margin differ, and our computation of EBITDA and EBITDA Margin may not be comparable to other similarly titled measures of other companies.

***ROIC***

We calculate ROIC as net operating profit after tax for the relevant year divided by invested capital.

We define net operating profit after tax as operating profit for the relevant year minus income tax adjustment. Income tax adjustment is defined as operating profit for the relevant year multiplied by our effective tax rate for the relevant year, the numerator of which is income tax and social contribution and the denominator of which is profit before tax. We define invested capital as total shareholders' equity minus goodwill minus intangibles assets plus current and non-current loans and financing plus debentures plus non-current related party loans liabilities plus current and non-current obligations from acquisition of investment plus dividend payable minus cash and cash equivalents minus non-current related party loans assets. Management believes ROIC is a meaningful measure because it measures capital efficiency by quantifying how well we generate operating profit relative to the capital that has been invested in our business and illustrates the profitability of a business or project taking into account the capital invested. Management uses ROIC to assist them in capital resource allocation decisions and in evaluating business performance.

Although ROIC is commonly used as a measure of capital efficiency, definitions of ROIC differ, and our computation of ROIC may not be comparable to other similarly titled measures of other companies.

***Free Cash Flow and Cash Conversion Rate***

We calculate Free Cash Flow as EBITDA for the relevant year minus change in working capital minus acquisition of property, plant and equipment and intangible assets. Change in working capital is calculated as the sum of changes in current assets and liabilities affecting the cash generated from operating activities in the statements of cash flow. Management believes that Free Cash Flow, which measures the ability to generate additional cash from business operations, is an important financial measure for use in evaluating our financial performance and ability to reduce debt, fund acquisitions and fund growth initiatives.

We calculate Cash Conversion Rate as Free Cash Flow for the year divided by EBITDA for the year. Management believes that Cash Conversion Rate is a useful indicator of our cash generation and efficiency in converting our operating profit into cash.

Our calculation of Free Cash Flow and Cash Conversion Rate may be different from the calculation used by other companies, including our competitors in the industry, and therefore, our measures may not be comparable to those of other companies.

**Industry and Market Data**

In this annual report, we present industry data, forecasts, information and statistics regarding the markets in which we compete as well as our analysis of statistics, data and other information that we have derived from third parties, including independent consultant reports, publicly available information, various industry publications and other published industry sources. Independent consultant reports, industry publications and other published industry sources generally indicate that the information contained therein was obtained from sources believed to be reliable. While we have compiled, extracted, and reproduced industry data from these sources, we have not independently verified the data. Similarly, internal surveys, industry forecasts and market research, which we believe to be reliable based upon our management's knowledge of the industry, have not been independently verified. Such information is supplemented where necessary with our own internal estimates and information obtained from discussions with our customers, taking into account publicly available information about other industry participants and our management's judgment where information is not publicly available. This information appears in *"Item 4.B. Information on the Company—Business Overview," "Item 5. Operating and Financial Review and Prospects*" and other sections of this annual report.

While we believe that the market data, industry forecasts and similar information included in this annual report are generally reliable, such information is inherently imprecise and the accuracy and completeness of such information is not guaranteed. Forecasts and other forward-looking information obtained from these sources are subject to the same qualifications and uncertainties as the other forward-looking statements in this annual report. See *"Cautionary Note Regarding Forward-Looking Statements."* In addition, assumptions and estimates of our future performance and growth objectives and the future performance of our industry and the markets in which we operate are necessarily subject to a high degree of uncertainty and risk due to a variety of factors.

Certain market, ranking and industry data included elsewhere in this annual report, including the size of certain markets and our size or position and the positions of our competitors within these markets, including our services relative to our competitors, are based on estimates by us. These estimates have been derived from management's knowledge and experience in the markets in which we operate, as well as information obtained from surveys, reports by market research firms, third-party industry publications and sources in the markets in which we operate and other publicly available information, and have not been verified by independent sources. Unless otherwise noted, all of our market share and market position information presented in this annual report is an approximation. References herein to Emergencia being a leader in a market or product category refer to our belief that we have a leading market share position in each specified market, unless the context otherwise requires. As there are no publicly available sources supporting this belief, it is based solely on our internal analysis of our results as compared to the results made available by our competitors. In addition, the discussion herein regarding our various end markets is based on how we define the end markets for our products, which products may be either part of larger overall end markets or end markets that include other types of products and services.

Solely for convenience, some of the trademarks, service marks, trade names and copyrights referred to in this presentation may be listed without the TM, SM© or® symbols, but we will assert, to the fullest extent under applicable law, the rights of the applicable owners, if any, to these trademarks, service marks, trade names and copyrights.

None of the publications, reports or other published industry sources referred to in this annual report were commissioned by us or prepared at our request. We have not sought or obtained the consent of any of these sources to include such market data in this annual report.

**Emerging Growth Company Status**

We qualify as an "emerging growth company," as defined in Section 2(a) of the Securities Act, as modified by the JOBS Act. As such, we are eligible to take advantage of certain exemptions from various reporting requirements that are applicable to other public companies that are not "emerging growth companies," and are not required to, among other things, (1) provide an auditor's attestation report on our system of internal controls over financial reporting pursuant to Section 404 of the Sarbanes-Oxley Act; (2) provide all of the compensation disclosure that may be required of non-emerging growth public companies under the Dodd-Frank Wall Street Reform and Consumer Protection Act; (3) comply with any requirement that may be adopted by the PCAOB regarding mandatory audit firm rotation or a supplement to the auditor's report providing additional information about the audit and the financial statements (auditor discussion and analysis); and (4) disclose certain executive compensation related items such as the correlation between executive compensation and performance and comparisons of the CEO's compensation to median employee compensation. Accordingly, the information about us available to investors will not be the same as, and may be more limited than, the information available to shareholders of a non-emerging growth company. If some investors find our Securities less attractive as a result, there may be a less active trading market for our Securities and the prices of our Securities may be more volatile.

We will remain an emerging growth company until the earlier of (1) the last day of the fiscal year following the fifth anniversary of the Closing of the Business Combination or (b) in which we have total annual gross revenue of at least $1.235 billion (as adjusted for inflation pursuant to SEC rules from time to time), and (2) the date on which (x) we are deemed to be a large accelerated filer, which means that the market value of our Class A Ordinary Shares held by non-affiliates exceeds $700 million as of the prior June 30th, or (y) the date on which we have issued more than $1.0 billion in nonconvertible debt during the prior three-year period.

**D.Risk Factors**

*The following risk factors apply to the business and operations of the Company. These risk factors are not exhaustive, and investors are encouraged to perform their own investigation with respect to the business, financial condition and prospects of the Company. You should carefully consider the risks and uncertainties described below, together with all of the other information in this annual report, including the sections titled "Cautionary Note Regarding Forward-Looking Statements," and "Item 5. Operating and Financial Review and Prospects," and our audited Consolidated Financial Statements and accompanying notes. The risks and uncertainties described below are not the only ones we face. Additional risks and uncertainties that we are unaware of, or that we currently believe are not material, or which are not identified because they are generally common to businesses, may also become important factors that adversely affect our business. If any of these risks actually occurs, alone or in combination with other events or circumstances, our business, financial condition, results of operations, future prospects and reputation could be materially and adversely affected.*

*Unless the context otherwise requires, all references in this subsection to "we," "us," "our" or the "Company" refer to Ambipar Emergency Response and its subsidiaries.*

**Risks Relating to Our Business and Industry**

***The success of integration of acquired companies, subjects us to a variety of risks that could adversely affect our operations and revenues.***

As part of our strategy to expand our operations in Brazil, North America and other jurisdictions, we acquire and invest in businesses that are complementary to ours, including through strategic mergers and acquisitions or investments. RIn 2020, we acquired the U.S. companies Allied International Emergency, LLC, One Stop Environmental LLC, Intracoastal Environmental LLC and Custom Environmental Services, Inc. In 2021, we acquired Orion Environmental Services Ltd., in Canada, Enviroclear Site Services Limited, in the United Kingdom, Controlpar Participações S.A., in Brazil, and Lehane Environmental and Industrial Services Limited, in Ireland, among other acquisitions. In 2022, we acquired First Response Inc., Graham Utility Hydrovac Services and Ridgeline Canada Inc., in Canada; Dracares Apoio Marítimo e Portuário Ltda., Flyone Serviço Aéreo Especializado, Comércio e Serviço Ltda. and CTA Serviços em Meio Ambiente Ltda., in Brazil; and Witt O'Brien's in the United States, among other acquisitions.In 2023, we acquired Girassol Apoio Marítmo Ltda, Ekman – Serviços Ambientais e Oceanográficos Ltda, Plimsoll Serviços Ltda, DFA Contracting Ltd, Reconditec Sistemas e Participações, RMC2 Soluções Ambientais Ltda, SMR (composed by entities SMR, SSMR, and SSR), Alberta, among other acquisitions.

The successful execution of mergers and acquisitions and the successful integration of such acquisitions is a critical element of our strategy. We may incur significant transaction costs to for the acquisition or incorporation of companies or assets and, even so, we may not be able to complete such transactions or, if we manage to complete them, they may not generate the expected benefits. In addition, we may be unable to identify suitable acquisition or strategic investment opportunities or may be unable to obtain any required financing or governmental licenses, findings of suitability, registrations, permits and approvals, and therefore may be unable to complete such acquisitions or strategic investments on favorable terms, if at all, and in accordance with regulatory requirements. We may decide to pursue acquisitions with which our investors may not agree, and we cannot assure investors that any acquisition or investment will be successful or otherwise provide a favorable return on investment. We also cannot guarantee that we will be able to identify successful acquisition candidates or that we will be successful in integrating these acquisitions.

Any acquisition or investment involves a series of risks and challenges that could adversely affect our business, including due to the failure of such acquisition to contribute to our business strategy or improve our image. As a result, we may not be able to generate the expected returns and synergies from our investments. In addition, the amortization of acquired intangible assets may decrease our net income.

------

[T](#ib885b07745664dce8cc23d0d35721f6b_7)[able](#ib885b07745664dce8cc23d0d35721f6b_7)[of](#ib885b07745664dce8cc23d0d35721f6b_7)[Contents](#ib885b07745664dce8cc23d0d35721f6b_7)

We may also face challenges in integrating acquired companies, including new employees and technologies, into our existing business, which may divest our capital and our management's attention to other business challenges and opportunities. In this regard, we may not be able to create and implement uniform and effective controls, procedures and policies, and we may incur in additional costs to integrate systems, people, distribution methods or operating procedures. In addition, we may not be able to integrate technologies from acquired businesses or retain clients, executives and key employees of the acquired businesses.

We may acquire the control of companies that have significant minority investors, or become minority investors in certain transactions. In such cases, our ability to effectively control and manage the business may be limited.

***We may face successor liability for contingencies and damages arising from our acquisitions that have not been identified prior to the relevant acquisition and may not be sufficiently indemnified under the terms of the applicable acquisition agreement.***

Our strategy of growing through acquisitions subjects us to potential successor liability risk with respect to legal claims incurred by target companies prior to our acquisition of their businesses. We may face liabilities for contingencies and the obligation to indemnify relating to, among other matters, (1) legal and/or administrative proceedings of the acquired company, including civil, regulatory, labor, tax, social security, environmental and intellectual property proceedings and (2) financial, reputational and technical issues, including those related to accounting practices, financial statement disclosures and internal controls, as well as other regulatory matters. These contingencies may not have been identified prior to the acquisition and may not be sufficiently indemnified under the terms of the acquisition agreement, which could have an adverse effect on our business and financial condition. Generally, in connection with acquisitions we often only conduct a limited due diligence prior to the closing of the acquisition. This practice increases the risk that after closing of the respective transaction certain risks or contingencies materialize that were not previously identified and which may adversely affect the acquired entity, the integration of the asset and us. Furthermore, although we endeavor to accurately estimate and limit environmental liabilities presented by the businesses or facilities to be acquired, some liabilities, including ones that may exist only because of the past operations of an acquired business or facility, may prove to be more difficult or costly to address than we then estimate. It is also possible that government officials responsible for enforcing environmental laws may believe that an environmental liability is more significant than we then estimate, or that we will fail to identify or fully appreciate an existing liability before we become legally responsible to address it. See "— *Failure to comply with socio-environmental laws and regulations, including with respect to the handling of hazardous waste, may adversely affect our business*."

Some purchase and sale agreements provide for caps and other restrictions on the liability of sellers for any contingencies and liabilities arising from the sale, which may, for example, be limited to representations and warranties made by the seller in the purchase and sale agreement, among others. Any indemnities that we receive or may receive from sellers of acquired companies may not be sufficient to protect or offset legal claims and liabilities or may not be fulfilled.

Unidentified pre-closing contingencies may lead us to negotiate a security package that does not cover the entire risk exposure of the business. In addition, we cannot ensure that any negotiated guarantees will be sufficient to cover future materialized contingencies, as these guarantees may have been used to pay other contingencies. Any collateral granted in our favor in the context of business acquisition may perish, depreciate or be affected in the event of insolvency or the existence of creditors who have preference over our right to indemnity and there may be no obligations of reinforcement or replacement of such guarantees.

We may be involved in legal disputes against the sellers regarding the risk allocation for these contingencies, which could increase our costs and turn into losses if we are not successful. We are also subject to tax authorities questioning corporate reorganizations. The tax authorities have already questioned and may question in the future tax benefits achieved as a result of corporate reorganizations and may disallow the tax benefits we claimed in a given year, charging the total amount due plus late payment interest and fines according to applicable legislation.

[T](#ib885b07745664dce8cc23d0d35721f6b_7)[able](#ib885b07745664dce8cc23d0d35721f6b_7)[of](#ib885b07745664dce8cc23d0d35721f6b_7)[Contents](#ib885b07745664dce8cc23d0d35721f6b_7)

Some companies we acquire may not deliver the expected result according to our financial and business expectations and, as a result, we may decide to dispose of some of our assets. However, we cannot guarantee that, in the event of disposals of assets, they will be adequately priced by the market and potential buyer, which could lead to accounting and financial losses on the sale. We may also be subject to having to respond for contingencies due to the divested asset, negatively affecting our provisions, results, cash and reputation.

Any of the above factors could adversely affect us, including our reputation, which would reduce acquisition-related benefits and cause material harm to our financial condition and future business.

***Our growth depends largely on our ability to successfully integrate companies acquired. We may not realize the expected benefits from recent or potential future acquisitions or may incur significant expenses in connection therewith, which could adversely affect our results of operations and financial condition*.**

The integration success of an acquisition or investment will depend on our ability to make accurate assessments with respect to operations, growth potential, synergies and other factors related to that business. Accordingly, we cannot guarantee that our acquisitions or investments will produce the results we expect when we enter into or complete a particular transaction. Our ability to continue to expand our business through acquisitions depends on several factors, including: (i) our ability to identify and assess opportunities, negotiate favorable terms and close potential target acquisitions; (ii) our ability to obtain funds to finance such transactions on favorable terms; and (iii) our ability to successfully integrate acquired businesses.

Expected benefits from recent acquisitions are necessarily based on projections and assumptions, which may not materialize as expected or which may prove to be inaccurate. Our ability to achieve the expected benefits and synergies will depend on successfully and efficiently integrating the businesses and operations of the newly acquired companies. We may encounter the following significant risks and challenges in integrating and recognizing expected benefits from recent acquisitions:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• potential interruption or reduction in the growth of our business, due to the diversion of management's attention to tasks related to the integration of the acquired companies and uncertainty about our management's relationship with the management of the acquired companies;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• disputes with the former owners of the acquired companies, including owners who remain as minority shareholders of the acquired companies, which can result in increased legal expenses, management distraction and the risk that we suffer an adverse judgment if we are not the prevailing party in the dispute;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• difficulties related to entry into jurisdictions with which we have limited or no prior experience, including due to having to operate in other languages, manage different types of currency, billing, and contracting needs, and comply with new laws and regulations, including labor laws and privacy laws that in some cases may be more restrictive on our operations than laws presently applicable to our business, and the potential of increased competition with new or existing competitors as a result of such acquisitions;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• insufficient internal controls from acquired businesses that we must remediate, and the need to modify or enhance our own internal controls, in each case resulting in increased administrative expense and risk that we fail to comply with the requirements of Section 404 of the Sarbanes-Oxley Act going forward, resulting in late filing of Exchange Act reports, loss of investor confidence, regulatory investigations and litigation;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• difficulties in coordinating sales and marketing efforts to effectively position our capabilities and drive product development;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• difficulties in achieving anticipated cost savings, synergies, business opportunities and growth prospects from combining the businesses of the newly acquired companies with ours;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• retention of employees, suppliers and other key partners of newly acquired companies;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• difficulties in anticipating and responding to actions that may be taken by competitors in response to our acquisitions; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• the assumption of successor liability and exposure to unknown or contingent liabilities of newly acquired companies, in particular companies we acquire without conducting a comprehensive due diligence process.

If we do not successfully manage these issues and other challenges that may inherently arise in the integration of the acquired businesses, we may not achieve the expected benefits of the acquisitions made and incur in unforeseen expenses, contingencies and succession responsibilities. As a result, our results of operations may be materially and adversely affected.

***The use of cash and significant indebtedness in connection with financing acquisitions could adversely impact our liquidity, limit our flexibility to respond to other business opportunities and increase our vulnerability to adverse economic and operating conditions.***

Our recent acquisitions were financed by cash and cash equivalents, in addition to indebtedness through the issuance of Debentures and the entry into the IBBA Loan Agreement, and we expect to fund future acquisitions in a similar manner. The use of available cash to finance recent acquisitions may reduce our liquidity, which may reduce the availability of our cash flow for working capital needs, dividends and capital expenditures or to pursue other potential strategic plans, which may affect our growth strategy and adversely affect our business and operating results. Borrowing to fund any cash purchase price would result in increased fixed obligations and could also include covenants or other restrictions that would impair our ability to manage our operations. See "—*We may not be able to raise sufficient funds to implement our business plan, renew our existing lines of credit or access new financing facilities on attractive terms or at all, which could have a material adverse effect on us*."

***We may be unable to comply with the financial and operating covenants set forth in the deeds governing our Debentures and certain financing agreement.***

On September 20, 2022, Emergencia issued the Second Issuance of Debentures, pursuant to the Second Deed of Debentures. On September 16, 2024, Emergencia issued the Third Issuance of Debentures, pursuant to the Third Deed of Debentures.In addition, on August 26, 2022, our subsidiary Ambipar USA entered into the IBBA Loan Agreement. The Deeds of Debentures and the IBBA Loan Agreement limit in certain circumstances, among other things, the extent to which we can:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• pay dividends and interest on equity or make other distributions to our stockholders;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• purchase or redeem capital stock;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• sell assets;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• consolidate or merge with or into other companies or transfer all or substantially all of its assets; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• carry out corporate restructurings; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• undertake a change of control.

As a result of these covenants, we may not be able to respond to changes in business and economic conditions and to obtain additional financing, if needed, and we may be prevented from engaging in transactions that might otherwise be beneficial to us.

[T](#ib885b07745664dce8cc23d0d35721f6b_7)[able](#ib885b07745664dce8cc23d0d35721f6b_7)[of](#ib885b07745664dce8cc23d0d35721f6b_7)[Contents](#ib885b07745664dce8cc23d0d35721f6b_7)

The Deeds of Debentures and the IBBA Loan Agreement require, and our future debt instruments may require, us to maintain under certain circumstances certain financial ratios and satisfy certain other financial condition tests. Our ability to meet these financial ratios and tests can be affected by events beyond our control, and we may not be able to meet those tests. The breach of any of these covenants could result in a default under our outstanding or future debt. Upon the occurrence of an event of default, the lenders could elect to declare all amounts outstanding under such debts, including accrued interest or other obligations, to be immediately due and payable. If amounts outstanding under such debts were accelerated, our assets might not be sufficient to repay in full those debts.

The Deeds of Debentures and the IBBA Loan Agreement also contain cross-default and cross-acceleration provisions. Under these provisions, a default or acceleration under one instrument governing our debt may constitute a default under our other debt instruments that contain cross-default and cross-acceleration provisions, which could result in the related debt and the debt under such other instruments becoming immediately due and payable. In such event, we would need to raise funds from alternative sources, which funds might not be available to us on favorable terms, on a timely basis or at all. Alternatively, such a default could require us to sell assets and otherwise curtail operations to pay our creditors. The proceeds of such a sale of assets or curtailment of operations might not enable us to pay all of our liabilities.

***Difficulties in managing our liquidity risk may adversely affect our financial and operating performance and limit our growth.***

Liquidity (i.e., ready access to funds) is essential to our business. Liquidity risk is the potential that we will be unable to meet our obligations as they come due because of an inability to generate sufficient cash flows from operations, to liquidate assets or obtain adequate funding. Our liquidity may be impaired by an inability to collect accounts receivable or any recoverable balances in a timely manner, an inability to sell assets or redeem investments, unforeseen outflows of cash or large claim payments, or an inability to access credit from banks or debt investors.

Our access to funding sources in amounts adequate to finance our activities or on acceptable terms could be impaired by factors that affect us specifically or the emergency response industry or economy in general. Factors that could detrimentally impact access to liquidity sources include a decrease in the level of our business activity as a result of a downturn in the markets in which we offer our products and services, operational problems that affects us, our customers, suppliers or third parties, or even the perception among market participants that we, or other market participants, are experiencing greater liquidity risk.

Market conditions or other events could also negatively affect the level or cost of funding, affecting our ongoing ability to accommodate liability maturities and deposit withdrawals, meet contractual obligations and fund asset growth and new business transactions at a reasonable cost, in a timely manner and without adverse consequences.

Any substantial, unexpected or prolonged change in the level or cost of liquidity could have a material adverse effect on our financial condition and results of operations, and could impair our ability to fund operations and meet our obligations as they become due and could jeopardize our financial condition.

***We may not be able to raise sufficient funds to implement our business plan, renew our existing lines of credit or access new financing facilities on attractive terms or at all, which could have a material adverse effect on us.***

We intend to continue to make investments to support our business growth and may require additional funds to respond to business challenges, including the need to develop new products and services, enhance our technology, scale and improve our operating infrastructure, or acquire complementary businesses and technologies. Accordingly, we may need to engage in equity, debt or convertible debt financings to secure additional funds.

Our ability to obtain additional capital, if and when required, will depend on our business plans, investor demand, our operating performance, markets conditions, our credit rating, and other factors.

------

[T](#ib885b07745664dce8cc23d0d35721f6b_7)[able](#ib885b07745664dce8cc23d0d35721f6b_7)[of](#ib885b07745664dce8cc23d0d35721f6b_7)[Contents](#ib885b07745664dce8cc23d0d35721f6b_7)

If we raise additional funds by issuing equity securities or securities convertible into equity securities, our shareholders may experience significant dilution of their ownership interests and the per share value of our Ordinary Shares may decline. Debt financing, such as credit facilities or corporate bonds, may require us to agree to covenants restricting our operations or our ability to incur additional debt. Debt financing may also require security arrangements including cash collateral agreements that restrict the availability of cash held as collateral. Any of those securities may have rights, preferences or privileges senior to the rights of our currently issued and outstanding equity or debt. In addition, future equity financing or replacement or refinancing of any debt financings may not be available on terms favorable to us or our shareholders, or at all.

In addition, there is no assurance that the holders of the Warrants will elect to exercise any or all Warrants, which could impact our liquidity position. Whether warrantholders will exercise their Warrants, and therefore the amount of cash proceeds we would receive upon exercise, is dependent upon the trading price of the Class A Ordinary Shares, the last reported sales price for which was $4.46 per share on June 23, 2025. Subject to the terms and conditions of the Warrant Agreement, each Warrant is exercisable for one Class A Ordinary Share at an exercise price of $11.50. Therefore, if and when the trading price of the Class A Ordinary Shares is less than $11.50, we expect that warrantholders would not exercise their Warrants. We could receive up to an aggregate of approximately $186.1 million if all Warrants are exercised for cash, but we would only receive such proceeds if and when the warrantholders exercise the Warrants. The Warrants may not be or remain in the money during the period they are exercisable and prior to their expiration and, therefore, it is possible that the Warrants may not be exercised prior to their maturity on March 3, 2028, even if they are in the money, and as such, may expire worthless with minimal proceeds received by us, if any, from the exercise of Warrants. To the extent that any of the Warrants are exercised on a "cashless basis," we will not receive any proceeds upon such exercise. As a result, we do not expect to rely on the cash exercise of Warrants to fund our operations. Instead, we intend to rely on other sources of cash to continue to fund our operations. See "*Item 5.B. Operating and Financial Review and Prospects—Liquidity and Capital Resources*."

If we are unable to obtain adequate financing or financing on terms satisfactory to us when we require it, we may be unable to pursue certain business opportunities and our ability to continue to support our business growth and to respond to business challenges or unforeseen circumstances could be impaired and our business may be harmed.

***Our emergency response services are subject to operational and security risks, including as a result of the handling of hazardous substances, and any accidents that occur during the performance of our services may expose us to significant civil, labor, environmental and criminal liabilities and adversely affect our business, results of operations, financial condition and reputation.***

The provision of emergency response services to our customers involves operational risks such as equipment defects or malfunctions, problems in training professionals, failures and natural disasters, which can result in the release of hazardous materials, accidents involving our employees, or the need to shut down or reduce the operation of our facilities while corrective actions are taken. Our employees generally work in potentially dangerous conditions, which exposes us to possible liability, in line with applicable occupational safety standards, for personal injury and other accidents, business interruptions and the damage or destruction of property. Our equipment and vehicle training and maintenance programs may not be adequate to cover all of our potential liability, as well as to prepare our professionals to perform the necessary activities during the provision of customer service without causing damage or accidents. For example, we operate in the handling of hazardous waste and other dangerous substances from different sources. Although we seek to minimize our exposure to operational risks through comprehensive training, compliance and response and recovery programs, including internal safety protocols in accordance with the applicable legal and regulatory requirements, we cannot guarantee that irregularities will not arise or that external factors will not cause accidents. Fires or other incidents involving our team in the provision of emergency response services can cause our reputation to be questioned and subject us to the filing of lawsuits and administrative proceedings and launch of regulatory investigations against us, with possible imposition of fines or other penalties. Further, a major operational failure, even if suffered by a competitor, may bring enhanced scrutiny and regulation of our industry, with a corresponding increase in operating expense.

In addition, some contracts entered into with customers allocate the responsibility for damages caused by irregularities committed during the execution of activities to us, thus increasing our liability exposure.

Any accidents that occur during the performance of our services may damage our reputation and result in significant costs and, consequently, adversely affect our business, financial condition and results of operations.

***Our performance depends on favorable labor relations with our employees and our compliance with labor laws. Any deterioration of those relations or increase in labor costs due to our compliance with labor laws could adversely affect our business.***

As of December 31, 2024, we employed 5,137 in Brazil, 860 in other parts of Latin America, 1,307 in North America and 131 in Europe. In Brazil, 100% of the Company's employees are covered under collective bargaining agreements, involving approximately 100 agreements. Substantially all employees covered under collective bargaining agreements are covered under agreements that expire in one year or later. We have not experienced any labor-related work stoppage at any location in over ten years. We believe our relationship with our employees and union leadership is satisfactory. At any given time, we will likely be in some stage of contract negotiations with various collective bargaining units. In the absence of agreements, we may become subject to labor disruption at one or more of these locations, which could have an adverse effect on our financial results.

***Our market is highly competitive. Failure to compete successfully could have a material adverse effect on our business, financial condition and results of operations.***

The environmental and industrial field services industry is highly competitive. Competition is primarily based on geographic location, breadth of services, quality and reliability of operations, brand recognition and reputation, customer support, and price. We face direct competition from large multinational companies as well as numerous regional and local companies across our geographic markets. Competition is likely to exist in new locations to which we may expand in the future. Some of these competitors may have greater financial and operational resources, strategic geographic locations, advanced technology, may provide service offerings that we do not provide, and may have flexibility to reduce prices or other competitive advantages that could make it difficult for us to compete effectively. We may also face competition from new entrants, including competitors employing new or alternative technologies.

Our revenue derives mainly from contract renewals and new contract signings. We may be unable to renew contracts at historical price levels or at all or to obtain additional contracts at historical rates or at all as a result of competition. We may also elect to exit or not participate in low margin customer relationships. Price reductions or our inability to increase prices could significantly and adversely affect our results of operations.

If we were to lose market share or if we were to lower prices to address competitive issues, it could negatively impact our financial condition, results of operations and cash flows.

***Unfavorable conditions in our industry or the global economy could limit our ability to grow our business and negatively affect our results of operations.***

Uncertainty and negative trends in general economic conditions, including recessions or fear of recessions and significant tightening of credit markets, may create a difficult operating environment for our industry and the industry of our customers. Our business is dependent upon activity levels in cyclical industries, such as chemical and petrochemical. Challenges our customers may face, such as low demand for their products and services, willingness or capacity of their customers to make payment on obligations, or the returns on other assets, may affect us. If these cyclical industries slow significantly as a result of recessionary conditions, the business we receive from them would likely decrease. A weak economy generally results in lower activity levels and a decline in infrastructure, construction and demolition projects, which could negatively affect demand for our services. Consumer uncertainty and the loss of consumer confidence may also decrease overall economic activity and thereby reduce demand for the services we provide. Further, a challenging economic environment may cause some of our customers to suffer financial difficulties and ultimately to be unable or unwilling to pay amounts owed to us. A decline in industrial projects may also result in increased competitive pricing pressure and increased customer turnover, resulting in lower revenue and increased operating costs.

In addition, many factors, including factors that are beyond our control, may impact our results of operations or financial condition and our overall success by affecting our access to capital. These factors include recessions or fear of recessions, interest rates, unemployment levels, conditions in the housing market, immigration policies, government shutdowns, trade wars and delays in tax refunds, as well as events such as natural disasters, acts of war, terrorism, catastrophes and pandemics. In addition, the increased pace of consolidation in certain industries may result in reduced overall spending on our offering.

General worldwide economic conditions have experienced significant instability in recent years including the recent global economic uncertainty and financial market conditions caused by war and other armed conflicts, including the ongoing conflicts between Russia and Ukraine, Hamas and Israel and resultant escalating tensions in the region involving the Gaza Strip, Iran, Hezbollah in Lebanon and the Houthi in Yemen. See "—We are c*urrently operating in a period of economic uncertainty and capital markets disruption, which has been significantly impacted by geopolitical instability due to war and other armed conflicts. Our business, financial condition and results of operations may be materially adversely affected by any negative impact on the global economy and capital markets resulting from the conflicts in Ukraine, in the Gaza Strip or from any other geopolitical tensions*."

The United States has recently experienced historically high levels of inflation which have recently started falling. According to the U.S. Department of Labor, the annual inflation rate for the United States reached approximately 9.1% for June 2022, slowed to 4.1% in 2023, and decreased to 2.9% in 2024. In the event that the trend of falling inflation reverts going forward, we may experience an escalation in our operating costs, including employee compensation and general corporate expenses, which could reduce cash flow and operating income. As of the date of this annual report, we have not experienced material impacts to our business performance from inflationary pressure.

Actual events involving limited liquidity, defaults, non-performance or other adverse developments that affect financial institutions, transactional counterparties or other companies in the financial services industry or the financial services industry generally, or concerns or rumors about any events of these kinds or other similar risks, have in the past and may in the future lead to market-wide liquidity problems. For example, on March 10, 2023, Silicon Valley Bank failed and was taken into receivership by the Federal Deposit Insurance Corporation; on March 12, 2023, Signature Bank and Silvergate Capital Corp. were each swept into receivership; the following week, a syndicate of U.S. banks infused $30 billion in First Republic Bank; and later that same week, the Swiss Central Bank provided $54 billion in covered loan and short-term liquidity facilities to Credit Suisse Group AG, all in an attempt to reassure depositors and calm fears of a banking contagion. Our ability to effectively run our business could be adversely affected by general conditions in the global economy and in the financial services industry. Various macroeconomic factors could adversely affect our business, including fears concerning the banking sector, changes in inflation, interest rates and overall economic conditions and uncertainties. A severe or prolonged economic downturn could result in a variety of risks, including our ability to raise additional funding on a timely basis or on acceptable terms. A weak or declining economy could also impact third parties upon whom we depend to run our business. Increasing concerns over bank failures and bailouts and their potential broader effects and potential systemic risk on the banking sector generally and on the emergency response industry and its participants may adversely affect our access to capital and our business and operations more generally. Although we assess our banking relationships as we believe necessary or appropriate, our access to funding sources in amounts adequate to finance or capitalize our current and projected future business operations could be significantly impaired by factors that affect us, the financial institutions with which we have arrangements directly, or the financial services industry or economy in general.

We cannot predict the timing, strength or duration of any economic slowdown or recovery. In addition, even if the overall economy is robust, we cannot assure you that the market for services such as ours will experience growth or that we will experience growth.

If there is an economic downturn that affects our current and prospective customers, or if we are unable to address and mitigate the risks associated with any of the foregoing, our business, financial condition and results of operations could be adversely affected.

***We are currently operating in a period of economic uncertainty and capital markets disruption, which has been significantly impacted by geopolitical instability due to war and other armed conflicts. Our business, financial condition and results of operations may be materially adversely affected by any negative impact on the global economy and capital markets resulting from the conflicts in Ukraine, in the Gaza Strip or from any other geopolitical tensions.***

Global markets have recently experienced volatility and disruption following the escalation of geopolitical tensions, the start of military conflict between Russia and Ukraine, Hamas and Israel and resultant escalating tensions in the region involving the Gaza Strip, Iran, Hezbollah in Lebanon and the Houthi in Yemen.

On February 24, 2022, Russian military forces launched a full-scale military invasion of Ukraine, and since then there has been continued sustained conflict and disruption in the region. Although the length and further impact of the ongoing military conflict is highly unpredictable, the conflict in Ukraine has led and may continue to lead to market disruptions, including significant volatility in commodity prices (in particular oil and gas), credit and capital markets, increase in our energy and other input costs, and supply chain interruptions for some of our and our clients' equipment and vehicles' components, including as a result of uncertainties with regard to Russia's production and export of oil and gas, aluminum and other materials. We are continuing to monitor the situation in Ukraine and globally and assessing its potential impact on our business.

In response to Russia's prior annexation of Crimea, recognition of two separatist republics in the Donetsk and Luhansk regions of Ukraine and subsequent military interventions in Ukraine, the United States, the United Kingdom, the European Union and several other countries have imposed or are imposing far-reaching sanctions and export control restrictions on Russian entities and individuals, including an agreement to remove certain Russian financial institutions from the Society for Worldwide Interbank Financial Telecommunication (SWIFT) payment system. Additional potential sanctions and penalties have also been proposed and/or threatened. These and any additional sanctions, as well as any counter responses by the governments of Russia or other jurisdictions, and prolonged unrest, intensified military activities and/or the implementation of more extensive sanctions and embargoes could lead to further regional instability, geopolitical shifts and adverse effects on macroeconomic conditions, security conditions, currency exchange rates and the global financial markets generally and reduce levels of economic activity as well as increase financial markets volatility, potentially making it more difficult for us to obtain additional funds.

Furthermore, sanctions against Russia continue to evolve, particularly targeting the energy sector, including oil, gas, and infrastructure, imposed by the United States and the European Union. These restrictions have contributed to fluctuations in fuel prices and changes in global supply chains, impacting production costs and operational expenses. Additionally, disruptions in the agricultural sector, including Russia's blockade of Black Sea ports, have affected Ukraine's grain exports, exacerbating volatility in global food prices and supply chains. These factors could lead to increased costs, supply chain disruptions, and overall market uncertainty, all of which may adversely affect our business operations, financial condition, and results.

On October 7, 2023, Hamas militants and members of other terrorist organizations infiltrated Israel's southern border from the Gaza Strip and conducted a series of terror attacks on civilian and military targets. Thereafter, these terrorists launched extensive rocket attacks on Israeli population and industrial centers located along the Israeli border with the Gaza Strip. Shortly following the attack, Israel's security cabinet declared war against Hamas.

Israel has also faced attacks from Hezbollah in Lebanon and there have been disruptions to global shipping routes in the Red Sea from Houthi rebels.

In January 2025, Israel and Hamas reached a ceasefire agreement, halting the exchange of hostilities. The agreement includes a 15-month truce. However, the war resulted in the displacement of 90% of Gaza's population and led to hundreds of hostages being taken by Hamas. Persistent tensions and underlying political instability between the two sides create a risk of renewed direct conflict and potential resumption of warfare. The intensity and duration of the current Israel-Hamas war and the larger regional conflict is difficult to predict, and as are such war's economic implications on our business and operations, the global supply chain and on the global geopolitical instability.

While we do not have any employees, staff, consultants, operations, materials or equipment located in Israel or the surrounding region, Ukraine, Russia or Belarus, some of our clients and suppliers may have employees, staff, consultants, operations, materials or equipment located in Israel or the surrounding region, Ukraine, Russia or Belarus, which could adversely affect our business or the services being provided to us. Likewise, in recent years, diplomatic and trade relationships between the U.S. government and China have become increasingly frayed and the threat of a takeover of Taiwan by China has increased, which may also adversely affect our business or the services we provide for the same reasons.

Cybersecurity organizations in many countries have published warnings of increased cybersecurity threats to businesses, and external events, like the conflict between Russia and Ukraine or the political tensions between China and Taiwan, may increase the likelihood of cybersecurity attacks. Any failure or security breach of information systems or data could result in a violation of applicable privacy and other laws, significant legal and financial exposure, damage to our reputation or a loss of confidence in our security measures. See "—*Breaches of, or significant interruptions experienced by, our information technology systems and those of our third-party service providers or breaches of data security could adversely affect our business, reputation and financial condition*."

Any of the above mentioned factors could affect our business, prospects, financial condition, and operating results. The extent and duration of military action, sanctions and resulting market disruptions are impossible to predict, but could be substantial. Any such disruptions may also magnify the impact of other risks described in this form.

***We, our subsidiaries, affiliates, direct and indirect controlling shareholders and members of our management, or companies with which management has been involved with in the past, have been in the past and may in the future be subject to legal, administrative or arbitration disputes or investigations. Any disputes or investigations may adversely affect our results of operations, financial condition and reputation.***

We, our subsidiaries, our direct and indirect controlling shareholders and members of our management are and may in the future become subject to legal, administrative or arbitration proceedings, investigations and claims regarding civil, commercial, tax, labor, socio-environmental, criminal, tort and other matters, brought against us by customers, suppliers, regulators, governmental authorities or other third-parties.

In addition, certain of our affiliates within the environmental segment of the Ambipar Group, including Ambitec S.A., as well as certain directors and executive officers of the Ambipar Group, are defendants in one or more lawsuits in Brazil, which may lead to the imposition of fines and other regulatory sanctions. Although we are not directly involved in any such proceedings, an adverse outcome could result in negative media coverage, adversely impact in our reputation and the price of our Class A Ordinary Shares.

We cannot guarantee that the results of any such proceedings, investigations and claims will be favorable to us or any such other defendants, as applicable, or that the liabilities arising from them will be adequately provisioned. Any litigation, investigation or claim, whether meritorious or not, could harm our reputation and restrict the conduct of our business, will increase our costs and may divert management's attention, time and resources, which may in turn harm our business, financial condition and results of operations. Insurance might not cover such claims, might not provide sufficient payments to cover all the costs to resolve one or more such claims and might not continue to be available on terms acceptable to us. A claim brought against us for which we are uninsured or underinsured could result in unanticipated costs, potentially harming our business, financial position and results of operations.

***Losses not covered by insurance policies or that exceed the respective indemnity limits, as well as failure to renew insurance policies under conditions favorable to us, may have an adverse effect on our business.***

Our operations involve high-risk services and may subject us to liability claims by employees, contractors or other third parties, including as a result of accidents that may occur at our units or at customers' sites. While we currently maintain insurance in connection with our business, including, among other coverages, employment practices liability insurance, civil liability insurance, property damage insurance, and machinery and equipment insurance, these insurance policies are subject to deductibles and coverage limitations. Although we endeavor to purchase insurance coverage appropriate to our risk assessment, we are unable to predict with certainty the frequency, nature or magnitude of claims for direct or consequential damages, and as a result, we cannot guarantee that our insurance policies will be available or sufficient to cover eventual damages arising from any type of claim.

The scope and limits of such insurance may not be sufficient to cover the types or extent of claims or loss that may be incurred or received, such as cyber-attacks, wars, acts of God, force majeure or the interruption of certain activities. Even in the event of a claim covered by our policies, we cannot guarantee that payment will be made in a timely manner, or in a sufficient amount to fully offset the losses arising from such claim. The successful assertion of one or more large claims against us that exceeds available insurance coverage or changes in our insurance policies, including premium increases or the imposition of large deductible or co-insurance requirements, could have a material adverse effect on our financial condition, operating results and reputation. In addition, there may be risks for which we do not maintain or procure insurance coverage or for which the insurance coverage may not respond. For example, we do not maintain separate cyber liability insurance. A partially or completely uninsured claim against us, if successful and of sufficient magnitude, could have a material adverse effect on our business, financial condition and results of operations. Further, if we fail to pay an insurance premium, the insurance companies may deny reimbursements.

As we grow, our insurance coverage may not be sufficient to protect us from any loss now or in the future and we may not be able to successfully claim our losses under our current insurance policies on a timely basis, or at all. Moreover, we cannot guarantee that we will be able to maintain insurance policies at reasonable commercial rates or on acceptable terms, or contracted with the same or similar insurance companies. Due to the variable condition of the insurance market, we may experience in the future, increased insurance retention levels and increased premiums or unavailability of insurance. Higher deductibles could result in more volatility in our results of operations as well. Any future difficulty in obtaining insurance could also impair our ability to secure future contracts, which may be conditioned upon the availability of adequate insurance coverage. Our inability to obtain and maintain appropriate insurance coverage could cause a substantial business disruption, adverse reputational impact, and regulatory scrutiny and, as a result, could have a material adverse effect on our business financial condition and results of operations.

***We may not be successful in renewing strategic lease agreements or at terms and conditions favorable to us.***

In order to improve our customer experience with efficient and expeditious services, our facilities are located at strategic locations, which we lease from third parties, including one of our affiliates. See "*Item 7.B. Major Shareholders and Related Party Transactions—Related Party Transactions*." If we are unable to renew the lease agreements for our facilities, which have varying terms and conditions, at reasonable prices, terms and conditions, or if we are required to relocate to areas that are not as functional, we could be subject to an interruption or delay in the provision of our services, which would adversely affect our financial condition and results of operation. In addition, the renewal of lease agreements on less favorable terms may reduce the profitability of our facilities and adversely affect our results of operations.

We have entered into lease agreements that are not registered or endorsed before a notary public, or that are not properly registered with the property registry, which may result in an obligation for us to vacate the property during the term of the lease agreement if the landlord sells the leased property and the acquirer has no interest in continuing the lease. In Brazil, where a significant number of our facilities is located, tenancy laws and regulations set forth that, if the leased property is sold to a third party during the contractual term, the acquirer is not required to respect the terms and conditions of the lease, unless (a) the lease is in for a specified length; (b) a covenant allowing the tenant to enforce the lease in the event of a sale is included in the lease agreement; and (c) the contract has been registered with the competent real estate registry office. Considering that some of our lease agreements do not meet these requirements, if our landlords decide to sell the leased properties under these agreements, the acquirers may request that we vacate the property within 90 days from the receipt of a notice to vacate.

Any failure to extend, renew or replace on acceptable terms a significant portion of our lease agreements could have a material adverse effect on our business, financial condition, results of operations and cash flows.

***Breaches of, or significant interruptions to, our information technology systems and those of our third-party service providers or breaches of data security could adversely affect our business, reputation and financial condition.***

We rely upon information technology networks and systems, including the information technology systems of our third-party service providers, to operate our business. Our systems include, but are not limited to, (i) the Integrated Environmental Management System (*SIGA — Sistema Integrado de Gerenciamento Ambiental*), a tool for operations, administrative and financial management control of environmental processes, (ii) the Environmental Management System (*SGA — Sistema de Gerenciamento Ambiental*), which, among other things, controls environmental licenses, conditions, deadlines and cost of licensing and presents environmental projects' and programs' metrics and panels, (iii) the Territory Management System (*SGT — Sistema de Gerenciamento Territorial*), which is used to register real estate property and landlords and control topography, reports, contracts and royalty payments; (iv) the Operating Management System (*SGO — Sistema de Gerenciamento Operacional*), which provides on-demand management of key performance indicators, and (v) SAP Business One, an enterprise resource planning software.

In the ordinary course of our business, we collect, process, transmit and store sensitive information, including personal information, credit information and other sensitive data of our customers, suppliers and employees. We also have outsourced elements of our operations to third parties, and as a result we manage a number of third-party service providers who may receive access to our confidential information or information technology systems. Our internal computer systems, and those of third-party service providers or business partners on which we rely, and the large amounts of confidential information stored on those systems, are vulnerable to damage from physical, electronic or technical break-ins, accidental or intentional exposure of our data by employees, independent contractors, third-party service providers, customers or others with authorized access to our networks, computer viruses, malware, ransomware, unauthorized access, denial of service, "phishing attacks" and other cyberattacks, natural disasters, fire, terrorism, war, telecommunication, electrical failures or disruptive incidents that could result in actual or attempted data breaches, unauthorized access to, mishandling, misuse or disclosure of our confidential information, corruption or encryption of, or loss of sensitive or proprietary data, including personal information, or network failures or interruptions that may result in disruption of service or damaged systems.

Although we have security measures and procedures in place to mitigate risks associated with cybersecurity incidents and attacks, these security measures and procedures may not be adequate or sufficient to mitigate such risks and avoid security breaches, incidents, attacks and exposures. Cyberattacks by malicious third parties are increasing in their frequency, levels of persistence, sophistication and intensity, and are being conducted by sophisticated and organized groups and individuals with a wide range of motives (including, but not limited to, industrial espionage) and expertise, including organized criminal groups, "hacktivists," nation states and others. Because the techniques used to obtain unauthorized access to, or to sabotage, systems change frequently and often are not recognized until launched against a target, we may be unable to anticipate these techniques or implement adequate preventative measures. We may also experience security breaches that may remain undetected for an extended period. If our systems are damaged or cease to function properly due to any number of causes, ranging from catastrophic events to power outages to security breaches, and our business continuity plans do not effectively compensate, we may suffer interruptions in our ability to manage operations, and would also be exposed to a risk of loss, including financial assets or litigation and potential liability, which could materially adversely affect our business, financial condition, results of operation and reputation. Further, our reliance on internet technology may create additional opportunities for cybercriminals to exploit vulnerabilities.

We exercise little or no control over third party systems, which increases our vulnerability to problems with their systems. Our operations and results may be adversely affected if there is any interruption in the provision of information technology services to us, whether due to omissions, including those related to obtaining third party consent or licenses for intellectual property used in the equipment or software they manufacture or use, or failure by these service providers to fulfill their obligations to us. If we are unable to maintain or renew contracts with current service providers, we may have trouble integrating our systems with new providers, which may cause operational problems. In addition, the replacement of these service providers may not occur in a timely manner or cause failures in the transition period, which may also affect our operations. Finally, if the suppliers discontinue the services provided to us, we may suffer a material adverse effect on our operations.

Any interruption, disruption or breach of our systems or the systems of third party service providers which we rely upon could adversely affect our business operations and/or result in the loss or unauthorized access, use or disclosure of critical or sensitive confidential information or intellectual property, and could result in financial, legal, business and reputational harm to us. For example, interruptions or failures in our information technology systems caused by accidents, malfunctions or malicious acts could hinder our timely response to emergency calls, which would damage our reputation with customers. We could incur liability, the further development of our current and future products and services could be delayed and our business could be otherwise adversely affected. In addition, investigating, responding to and remediating cybersecurity incidents or theft of our intellectual property or proprietary business information may be costly and time-consuming.

We and our vendors, like other commercial entities, have been, and will likely continue to be, subject to a variety of forms of cyberattacks with the objective of gaining unauthorized access to our systems and data or disrupting our operations. To date, none of these cyberattacks has, individually or in the aggregate, resulted in a security incident with a material effect on our operations or our financial condition, results of operations, liquidity, or cash flows. However, these cyberattacks could have a material impact in the future.

We do not maintain separate cyber liability insurance, and we cannot assure that any limitations of liability provisions in our contracts would protect us from potential losses for any liabilities or damages with respect to any particular claim relating to a security lapse or breach. Further, such insurance may not be available to us in the future on economically reasonable terms, or at all. See "— *Losses not covered by insurance policies or that exceed the respective indemnity limits, as well as failure to renew insurance policies under conditions favorable to us, may have an adverse effect on our business*."

***We are subject to evolving legal and regulatory risks related to artificial intelligence, particularly concerning potential future obligations arising from the European Union Artificial Intelligence Act and Brazil's Artificial Intelligence Framework Bill, even if we do not currently employ AI systems.***

We are facing increasing regulatory challenges as both the European Union and Brazil advance their efforts to establish frameworks for artificial intelligence governance. The EU AI Act, which came into effect on August 1, 2024, introduces strict limitations on AI systems that engage in cognitive-behavioral manipulation, social scoring, biometric identification, and real-time facial recognition in public spaces. It also classifies certain AI applications as high-risk, imposing obligations such as extensive documentation, human oversight, cybersecurity measures, and transparency requirements.

In parallel, Brazil is moving toward similar regulatory oversight. In December 2024, the Brazilian Senate approved a bill that now awaits a vote in the Brazilian Chamber of Deputies. If enacted, this legislation will establish significant compliance obligations, including prohibitions on AI activities deemed excessively risky, particularly those that exploit vulnerabilities or manipulate individuals into behaviors harmful to their health, safety, or legal rights. It will also introduce governance structures requiring adherence to the Brazilian General Data Protection Law - LGPD and enhanced security protocols

While we do not currently utilize AI systems in our operations, the evolving regulatory landscape, including the implementation of new laws and the updating of existing ones, presents potential legal risks. These regulations could impose new obligations on our company, even in the absence of current AI deployment. For example, if enacted, the Brazilian legislation could require adherence to specific governance structures and enhanced security protocols related to AI, regardless of our current practices. Similarly, the EU AI Act, though not directly applicable to our current operations, may create a precedent for future regulations in other jurisdictions where we operate, potentially leading to compliance complexities and costs. Therefore, monitoring these developments and proactively adapting our policies and procedures will be essential to mitigate potential legal risks associated with future AI regulations.

***We are subject to risks associated with non-compliance with the Brazilian General Data Protection Law - LGPD, General Data Protection Regulation – GDPR, and similar legislation of other countries that impose obligations in connection with the collection, storage, use, processing, disclosure, protection, transmission, retention and disposal of personal, sensitive, regulated or confidential data.***

We and our customers are subject to Brazilian and foreign privacy and data protection-related laws and regulations that impose obligations in connection with the collection, storage, use, processing, disclosure, protection, transmission, retention and disposal of personal, sensitive, regulated and confidential data. Laws and regulations governing data privacy, data protection and information security are constantly evolving and there has been an increasing focus on privacy and data protection issues with the potential to affect our business. Compliance with any additional and evolving privacy laws or regulations in Brazil or in other jurisdictions applicable to us may be costly and time-consuming.

Any perceived or actual unauthorized disclosure of personal data, whether through breach of our network by an unauthorized party, employee theft, misuse or error or otherwise, including the personally identifiable information of our customers, suppliers, employees or third parties, could harm our reputation, impair our ability to attract and retain our clients, and subject us to claims or litigation arising from damages suffered by individuals.

Many foreign countries and governmental bodies, including in countries in which we currently operate, have laws and regulations concerning the collection, storage, use, processing, disclosure, protection, transmission, retention and disposal of personal, sensitive, regulated or confidential data. Such laws and regulations will be subject to interpretation by various courts and other governmental authorities, thus creating potentially complex compliance issues for us and our future customers and strategic partners. For more information on relevant privacy and personal data regulations, see "*Item 4.B. Business Overview—Regulatory Overview—Privacy and Data Protection.*"

We also may be bound by contractual obligations relating to our collection, use and disclosure of personal, confidential and other data.

While we strive to comply with all applicable privacy, data protection and information security laws and regulations, as well as our contractual obligations, posted privacy policies and applicable industry standards, such laws, regulations, obligations and standards continue to evolve and are becoming increasingly complex, and sometimes conflict among the various jurisdictions and countries in which we operate, which makes compliance challenging and expensive. In addition, any failure or perceived failure by us, or any third parties with whom we do business, to comply with laws, regulations, policies, industry standards or contractual or other legal obligations relating to privacy, data protection or information security may result in governmental investigations, inquiries, enforcement actions and prosecutions, private litigation, fines and penalties, adverse publicity or potential loss of business.

We expect that there will continue to be new proposed laws, rules of self-regulatory bodies, regulations and industry standards concerning privacy, data protection and information security in Brazil and other jurisdictions, and we cannot yet determine the impact such future laws, rules, regulations and standards may have on our business. Moreover, existing Brazilian and foreign privacy and data protection-related laws and regulations are evolving and subject to potentially differing interpretations, and various legislative and regulatory bodies may expand current or enact new laws and regulations regarding privacy and data protection-related matters. Additionally, the data subjects may be subject to differing privacy laws, rules and legislation, which may mean that they require us to be bound by varying contractual requirements application to certain other jurisdictions. Because global laws, regulations and industry standards concerning privacy and data security have continued to develop and evolve rapidly, compliance with such new laws or to changes to existing laws may impact our business and practices, require us to expend significant resources to adapt to these changes, or to stop offering our solutions in certain countries. These developments could adversely affect our business, results of operations and financial condition.

***The loss of members of our management may have a material adverse effect on our business, financial condition and results of operations.***

We have an experienced management team including local managers at our operating facilities and rely on the continued service of these senior managers to achieve our objectives, nurture our corporate culture and maintain a competitive position. We strive to retain our present management and identify, hire, train, motivate and retain other highly skilled personnel. However, senior managers may leave their positions for a variety of reasons, some of which we cannot control. In the event one or more senior managers depart, we may be unable to replace them with individuals with the same level of experience and qualifications and we may face challenges to maintain our culture. The loss of members of our management for any reason could limit our ability to implement our strategic plans and adversely affect our business, financial condition and results of operations.

***The estimates of market opportunity and forecasts of market growth included in this annual report may prove to be inaccurate. Even if the market in which we compete achieves the forecasted growth, our business could fail to grow at similar rates, if at all.***

This annual report contains market and industry data, estimates and statistics obtained from third-party sources. While we believe such information to be reliable in general, we have not independently verified the accuracy or completeness of any such third-party information. Such information may not have been prepared on a comparable basis or may not be consistent with other sources. Similarly, this annual report contains information based on or derived from internal company surveys, studies and research that have not been independently verified by third-party sources. Industry data, projections and estimates are subject to inherent uncertainty as they necessarily require certain assumptions and judgments.

In addition, the market for environmental and industrial services is relatively new, fragmented and will experience changes over time. Data market estimates and growth forecasts are uncertain and based on assumptions and estimates that may be inaccurate. Our addressable market depends on a number of factors, including changes in the competitive landscape, technological changes, data security or privacy concerns, customer budgetary constraints, changes in business practices, changes in the regulatory environment, and changes in economic conditions. Moreover, geographic markets and the industries we operate in are not rigidly defined or subject to standard definitions. Accordingly, our use of the terms referring to our geographic markets and industries may be subject to interpretation, and the resulting industry data, projections and estimates may not be reliable. Our estimates and forecasts relating to the size and expected growth of our market may prove to be inaccurate and our ability to produce accurate estimates and forecasts may in the future be impacted by the economic uncertainty, as well as with other macroeconomic factors to which we are subject (see "— *Risks Relating to the Markets where we Operate*"). Even if the market in which we compete meets the size estimates and growth rates we forecast, our business could fail to grow at similar rates, if at all. For these reasons, you should not place undue reliance on such information.

***Our inability or failure to protect our intellectual property or our infringement of the intellectual property of third parties may negatively impact our operating results, divert management and key personnel from the business operations and could harm our financial condition and reputation.***

We rely on a combination of trade secret, trademark, copyright laws and other rights, as well as confidentiality procedures, contractual provisions and our information security infrastructure to protect our proprietary brands, technology, processes and other intellectual property as well as those we license from other entities within the Ambipar Group. See "*Item 7.B. Major Shareholders and Related Party Transactions—Related Party Transactions*." The steps we take to protect our intellectual property rights may not be adequate, or may not effectively prevent unauthorized use or disclosure of our intellectual property or confidential information. In addition, the pursuit of a claim against a third party for infringement or misappropriation of our intellectual property rights or confidential information could be costly, and any such efforts may not be successful or could be met with defenses, counterclaims, and countersuits attacking the validity and enforceability of our intellectual property rights. Many companies have encountered significant problems in enforcing and defending intellectual property rights in various jurisdictions globally. The legal systems of certain countries, particularly certain developing countries, do not favor the enforcement of intellectual property, which could make it difficult for us to stop the infringement of our intellectual property or marketing of competing services in violation of our intellectual property rights generally. Our failure to obtain pending trademark applications and generally secure, protect and enforce our intellectual property rights could adversely affect our brand and adversely impact our business.

We cannot guarantee that our current and future services, or the use of our brands or technology will not infringe third-party intellectual property. There may be third-party intellectual property of which we are currently unaware that covers our services, brands or technology. Third parties may engage in legal proceedings against us or our customers, who in turn may seek indemnification from us. Any such claims of intellectual property infringement or claims for indemnification, even those without merit, could be expensive and time-consuming to defend, result in us being required to pay possibly significant damages, causing us to cease providing services that allegedly incorporate a third party's intellectual property, require us to enter into potentially costly royalty or licensing agreements in order to obtain the right to use a third party's intellectual property, although royalty or licensing agreements may not be available to us on acceptable terms or at all. If we are unable to obtain the necessary licenses or other rights, we may be forced to acquire or develop alternate technology, which could be costly, time-consuming, or impossible. Any of the preceding could have a negative impact on our operating results, divert management and key personnel from the business operations and could harm our financial condition and reputation.

For example, we use proprietary software in our activities, which are developed internally by our employees. Although any software developed in-house legally belongs to us, we may be subject to lawsuits filed by ex-employees claiming ownership of such software. In both cases, we may be ordered to abstain from using the software and to indemnify any such third-party. Although it is our policy to require our employees and consultants who may be involved in the conception or development of intellectual property to execute agreements assigning such intellectual property to us, we may be unsuccessful in executing such an agreement with each party who conceives or develops intellectual property that we regard as our own or such party may breach the assignment agreement. Litigation may be necessary to obtain ownership or to defend against claims challenging inventorship. If we or our licensors fail in any such litigation, in addition to paying monetary damages, we may lose valuable intellectual property rights, such as exclusive ownership of, or right to use, intellectual property or other proprietary information. Such an outcome could have a material adverse effect on our business. Even if we or our licensors are successful in defending against such claims, litigation could result in substantial costs and be a distraction to our management and other employees, and such claims could have a material adverse effect on our business, financial condition, results of operations, and prospects.

If we cannot protect our proprietary technology from intellectual property challenges, our ability to maintain our model and systems or facilitate products could be adversely affected.

***Intellectual property rights do not necessarily address all potential competitive threats.***

The degree of future protection afforded by our intellectual property rights is uncertain because intellectual property rights have limitations and may not adequately protect our business or permit us to maintain our competitive advantage. For example:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• others may be able to use brands and offer services that are similar to ours without infringing our intellectual property rights;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• others may independently develop similar or alternative proprietary software or technology without infringing our intellectual property rights;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• we may not develop additional proprietary technologies; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• our technology may become obsolete or inadequate, and we may not be able to successfully develop, obtain or use new technologies to adapt our models and systems to compete with other technologies as they develop.

Should any of these events occur, they could have a material adverse effect on our business, financial condition, results of operations, and prospects.

***If our trademarks are not adequately protected, then we may not be able to build name recognition in our markets of interest and our business may be adversely affected.***

If our trademarks are not adequately protected, then we may not be able to build name recognition in our markets of interest and our business may be adversely affected. Our trademarks may be challenged, infringed, circumvented, declared generic or determined to be infringing on other marks. We may not be able to protect our rights to these trademarks, which we need to build name recognition among potential partners or customers in our markets of interest. At times, competitors may adopt trademarks similar to ours, thereby impeding our ability to build brand identity and possibly leading to market confusion. In addition, there could be potential trademark infringement claims brought by owners of other registered trademarks or trademarks that incorporate variations of our trademarks. Over the long term, if we are unable to successfully register our trademarks and establish name recognition based on our trademarks, then we may not be able to compete effectively and our business may be adversely affected. Our efforts to enforce or protect our proprietary rights related to trademarks, domain names, copyrights, or other intellectual property may be ineffective and could result in substantial costs and diversion of resources and could adversely impact our business, financial condition, results of operations, and prospects.

***If we are unable to attract, develop and retain employees committed to our culture and brand, our operations may be adversely affected.***

Our success and future growth depend upon the continued services of our key employees, including highly-skilled technical experts, engineers, biologists and oceanographers, and, as a result, upon our ability to attract, develop and retain employees committed to our culture and brand. From time to time, there may be changes in our management team resulting from the hiring or departure of key employees, which could disrupt our business. The loss of one or more members of our key employees could harm our business, and we may not be able to find adequate replacements.

Competition for highly-skilled personnel is intense and we may not be able to attract, hire, train, retain, motivate and manage sufficiently qualified employees. Many of the companies with which we compete for experienced personnel have greater resources than we have.

As we expand our business in Brazil and abroad, we may be unable to identify, hire, develop and retain a sufficient number of employees with specific knowledge and skills in those geographies who are committed to our corporate culture. Such a failure could result in a reduction in the quality of customer service, and consequently compromise our brand and reputation.

If we fail to attract new personnel or fail to retain and motivate our current personnel, our business and future growth prospects would be harmed. We generally enter into non-competition agreements with our key employees, which prohibit these employees, if they cease working for us, from competing directly with us or working for our competitors for a limited period. We may be unable to enforce these agreements under the laws of the jurisdictions in which our employees work, and it may be difficult for us to restrict our competitors from benefiting from the expertise our former employees developed while working for us.

***We may not be able to manage our growth effectively, which could have a material adverse effect on our business, results of operations, financial condition and reputation.***

Over the last several years, we have experienced rapid growth in our business and number of employees, and we expect to continue to experience growth in the future. This rapid growth has placed, and may continue to place, significant demands on our management, processes, systems and operational, technological and financial resources.

Our ability to manage our growth effectively, integrate new employees and technologies into our existing business and attract new customers and maintain relationships with existing customers will require us to continue to retain, attract, train, motivate and manage employees and expand our operational, technological and financial infrastructure. Continued growth could strain our ability to develop and improve our operational, technological, financial and management controls, reporting systems and procedures, recruit, train and retain highly skilled personnel and maintain customers' satisfaction.

We cannot assure you that we estimate correctly the costs and risks associated with our expansion, either qualitatively or quantitatively, or that our current systems, procedures, business processes and management controls will be sufficient to support the expansion of our operations going forward, including expansion into new countries and new market segments.

Our failure to successfully manage our expansion process, or to maintain or increase our historical growth levels, could negatively affect our business, financial condition and results of operations.

***Failures in our risk management, compliance and internal control systems, policies and procedures may adversely affect our business, financial condition and reputation.***

We have developed risk management policies and procedures and we continue to refine them as we conduct our business. Our policies and procedures to identify, analyze, quantify, assess, monitor and manage risks may not be fully effective in mitigating our risk exposure. Our risk management methods may not predict future exposures or be sufficient to protect us against unknown and/or unmapped risks, which may be significantly greater than those indicated by the historical measures we use.

The information on which we rely or based on which we develop and maintain historical and statistical models may be incomplete or incorrect. Certain risk management methods adopted by us depend on the evaluation of publicly available industry data, which may not be entirely accurate, complete, updated or properly evaluated. As we expand into new lines of business, our risk management policies and procedures may not be able to adequately keep up with our current rapid rate of expansion, and may not be adequate or sufficient to mitigate risks.

In November 2023, we commenced, with the assistance of a consultancy firm, a comprehensive evaluation of our existing risk management frameworks and internal control mechanisms. This initiative was aimed at identifying key areas of deficiency and developing strategies for enhancement. By January 2024, the consultancy firm had completed their assessment and submitted a detailed report, along with a robust action plan, to our Chief Executive Officer (CEO) and Chief Financial Officer (CFO). Following this, in February 2024, our Board began a review of proposed measures to implement the action plan. Subsequently, they endorsed a strategic implementation agenda for 2024 designed to strengthen our policies and procedures, thereby significantly elevating the efficacy of our risk management and internal control systems.

In addition, our internal controls over financial reporting may not be effective and our independent registered public accounting firm may not be able to certify as to our effectiveness, which could have a significant and adverse effect on our business and reputation. Our current controls and any new controls that we develop may be inadequate because of changes in conditions in our business.

In 2024, we completed the integration of our risk and control framework with SAI360 (referred to internally as "a360"). This enterprise risk management system, suitable for a U.S. public company, now houses our catalog of identified risks and corresponding controls. We have also completed an assessment of inherent risk, residual risk, and control effectiveness using a360. This platform will facilitate the development of remediation plans to reduce risk levels and inform the design and implementation of new controls.

However, despite these enhancements, it is possible that unidentified risks remain, and the system's effectiveness depends on the accuracy and completeness of the initial risk mapping. We are also continuing to develop our finance and accounting team's expertise in U.S. public company accounting policies, practices, and internal controls over financial reporting, which remains an area of ongoing focus.

Further, despite the enhancements made to our internal control framework through the implementation of a360 in 2024, weaknesses may still be discovered in the future. Maintaining and improving the effectiveness of our disclosure controls and procedures and internal control over financial reporting will require ongoing, significant resource allocation, including accounting-related costs and management oversight. Any failure to develop or maintain effective controls, or difficulties encountered in their implementation or improvement, could adversely affect our operating results, cause us to fail to meet our reporting obligations, and potentially lead to a restatement of prior period financial statements. Ineffective disclosure controls and procedures and internal control over financial reporting could also harm investor confidence in our reported financial and other information.

Moreover, we are subject to the risks of errors and misconduct by our management, employees and independent contractors, which are often difficult to detect in advance and deter. Our compliance procedures and internal controls may not be sufficient to prevent, detect, and respond to all errors, misconduct, fraud, acts of corruption or violations of applicable laws and of our policies by our management, employees and other third parties with which we engage in the ordinary course of business. We could be held liable for any of such acts, which could result in penalties, fines, loss of permits or licenses, prohibition to bid or contract with the government.

Although we maintain insurance and use other traditional risk-shifting tools, such as third-party indemnification, to manage certain exposures, they are subject to terms such as deductibles, coinsurance, limits and policy exclusions, as well as risk of counterparty denial of coverage, default or insolvency. If our policies, procedures and internal controls do not adequately protect us from exposure, and our exposure is not adequately covered by insurance or other risk-shifting tools, we may incur losses that would adversely affect our business, financial condition, results of operations and reputation.

***In preparing our financial statements, we have identified material weaknesses in our internal control over financial reporting and, if we fail to remediate such material weaknesses (and any other ones) or implement and maintain effective internal controls over financial reporting, we may be unable to accurately report our results of operations, meet our reporting obligations or prevent fraud.***

Prior to the Business Combination, we were a private company with limited accounting personnel and other resources and processes necessary to address our internal control over financial reporting and procedures. Our internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external reporting purposes in accordance with the IFRS. In addition, we had to establish and implement disclosure controls and procedures, which include, without limitation, controls and procedures designed to ensure that information required to be disclosed by a company in those reports is accumulated and communicated to our management as appropriate to allow timely decisions regarding required disclosure.

In connection with the preparation of Ambipar Emergency Response's audited Consolidated Financial Statements as of and for the three years ended December 31, 2024, material weaknesses were identified in our internal control over financial reporting (including certain previous unremedied material weaknesses). A material weakness is a deficiency, or a combination of deficiencies, in internal control over financial reporting such that there is a reasonable possibility that a material misstatement of the annual or interim financial statements will not be prevented or detected on a timely basis. The material weaknesses identified relate to: (i) the consolidation process of recent acquisitions we made, due to the lack of a sufficient number of personnel in the acquired entities with an adequate level of knowledge and experience in the closing functions of our financial reports and related disclosures, to process the transition to the application of IFRS and International Accounting Standards and Interpretations issued by the IASB, consistent with our financial reporting requirements; and (ii) the design and operation of our accounting and financial reporting closing functions, in which required policies and procedures either were not designed or were not operating effectively at period end, resulting in a number of adjustments to our audited consolidated financial statements during the course of the audit.

Each material weakness may result in a misstatement of one or more account balances or disclosures that would result in a material misstatement of our audited Consolidated Financial Statements that would not be prevented or detected, and accordingly, we determined that these control deficiencies constitute material weaknesses.

For more information on these material weaknesses and our plan for remediating them, see "*Item 15. Controls and Procedures.*" We cannot assure you that our efforts will be effective or sufficient to remediate our material weaknesses or prevent any future material weakness in our internal control over financial reporting.

Under Section 404(b) of the Sarbanes-Oxley Act, until we cease to be an "emerging growth company" as such term is defined in the JOBS Act (see "*— Risks Relating to Our Securities—We are and will continue to be an "emerging growth company*" *and are subject to reduced SEC reporting requirements applicable to emerging growth companies*"), our independent registered public accounting firm is not required to attest to and report on the effectiveness of our internal control over financial reporting. Once such attestation from our independent registered public accounting firm is required, even if our management concludes that our internal control over financial reporting is effective, such firm, after conducting its own independent testing, may disagree with our assessment or may issue a report that is qualified if it is not satisfied with our internal controls or the level at which our controls are documented, designed, operated, or reviewed, or if it interprets the relevant requirements differently from us.

During documenting and testing our internal control procedures, in order to satisfy the requirements of Section 404 of the Sarbanes-Oxley Act, we may also identify other weaknesses and deficiencies in our internal control over financial reporting. In addition, if we fail to maintain the adequacy of our internal control over financial reporting, as these standards are modified, supplemented or amended from time to time, we may not be able to conclude on an ongoing basis that we have effective internal control over financial reporting in accordance with Section 404 of the Sarbanes-Oxley Act.

If we fail to remediate our existing or future internal material weaknesses or other deficiencies in our internal control over financing reporting and to maintain an effective internal control environment, we could suffer material misstatements in our financial statements, we could fail to meet our reporting obligations or fail to prevent fraud, investors could lose confidence in our financial reporting, and we could become subject to investigations, civil or criminal litigation, delisting proceedings, sanctions or other measures by the NYSE American, the SEC and other regulatory authorities. This could, in turn, limit our access to capital markets, harm our results of operations and lead to a decline in the trading price of our Securities.

***Our governance, risk management and compliance processes may fail to detect violations of anti-corruption and anti-money laundering laws and our standards of ethics, including as a result of the conduct of our managers, employees, suppliers, business partners and third parties who act in our name, interest or benefit, which may have a material and adverse impact on our business, financial condition, results of operations, reputation and market price of our Securities.***

We operate in jurisdictions that have a high risk of corruption according to the Corruption Perception Index from Transparency International. Mechanisms for preventing and combating bribery and corruption, money laundering, governance procedures, as well as our current internal procedures, may not be sufficient to ensure that all of our managers, employees, suppliers, business partners and third parties who act on our behalf, interest or benefit always act in strict compliance with our internal policies and laws and regulations aimed at preventing and combating corruption that we are subject to. These laws and regulations include the Brazilian Decree-Law No. 2,848/1940, Law No. 8,137/1990, Law No. 8,429/1992 (the Administrative Misconduct Law), Law No. 14,133/2021 (the Public Bidding Law), Law No. 9,613/1998, Law No. 12,846/2013, as amended and its regulation, Decree No. 11,129/2022 and Decree No. 12,304/2024 (collectively, "Brazilian Anti-Corruption Laws"), the United States Foreign Corrupt Practices Act of 1977 ("FCPA"), as amended, the United States Foreign Extortion Prevention Act of 2023, and the Bribery Act 2010 of the United Kingdom, as well as other standards related to the Convention on Combating Corruption of Foreign Public Officials in International Business Transactions of the Organization for Economic Cooperation and Development — OECD, including the guidelines issued by the Brazilian Comptroller General (collectively, "Anti-Corruption Laws").

In general, the Anti-Corruption Laws prohibit companies and their employees, shareholders or managers from making improper payments to government officials, directly or indirectly, for the purpose of obtaining or retaining business and/or other benefits. We cannot guarantee that our direct and indirect shareholders, directors, officers, employees and other third parties (including agents, suppliers and service providers) and the companies to which some business operations are outsourced will fully comply with the Anti-Corruption Laws and related policies. Our governance, policies, risk management and compliance processes may not be able to, for example: (i) detect, prevent or respond to violations of the Anti-Corruption Laws or similar legislation, as well as violations of our internal compliance policies; (ii) detect, prevent or respond to occurrences of fraudulent and dishonest behavior by our managers, employees, suppliers, customers, business partners or third parties acting on our behalf, interest or benefit; (iii) manage all risks identified in our risk management matrix and/or predict, identify or mitigate new risks; and (iv) detect, prevent or respond to other occurrences of behavior inconsistent with ethical and moral principles, which may materially and adversely affect our reputation, our business, financial conditions and operating results, as well as impact the market price of our Securities negatively. Public authorities are empowered to impose penalties on us if acts of corruption are inadvertently or intentionally committed by members of our management, employees and/or third parties acting on our behalf or in our interest. Under the terms of certain Anti-Corruption Laws, companies may be jointly and severally liable for the payment of a fine and full compensation for damage for unethical practices attributed to their affiliates and consortia members. As a result, we may be held liable for any such violations.

As we increase and scale our business, we may engage with new business partners and third-party intermediaries to market our products and services and obtain necessary permits, licenses and other regulatory approvals. In addition, we or our third-party intermediaries may have direct or indirect interactions with officials and employees of government agencies or state-owned or affiliated entities. We can be held liable for the corrupt or other illegal activities of these third-party intermediaries, our employees, representatives, contractors, customers and agents, even if we do not authorize such activities.

We are also subject to Brazilian Law No. 9,613 of March 3, 1998, as amended ("Money Laundering Prevention Law"), by which legal entities engaged in the sale of high value goods are subject to obligations related to identification of customers and operations, maintenance of records and submission of reports on financial operations to the competent authorities, among others. We are subject to the following sanctions in the event of non-compliance with the Money Laundering Prevention Law: (i) warnings; (ii) variable monetary fine; (iii) the revocation or suspension of our business licenses and (iv) the cancellation or suspension of the authorization to carry out the activity, operation or functioning. The application of any of these sanctions to us could adversely affect our reputation, business, financial condition, results of operations and the trading price of our Securities.

The existence of any current or past investigations, inquiries or proceedings of an administrative or judicial nature related to the violation of the Anti-Corruption Laws, against us, our managers, employees, suppliers, business partners or third parties acting on our behalf, interest or benefit may result in: (i) fines and indemnities in the administrative, civil and criminal spheres (the latter, to the administrators who contributed to the infraction); (ii) loss of unlawfully obtained benefits, including operating licenses; (iii) prohibition or suspension of our activities; and/or (iv) loss of rights to contract with the public administration, to receive incentives or tax benefits from any financing and resources from the public administration, among other applicable penalties. We may also be jointly and severally liable for the payment of a fine and full compensation for the damage due to practices contrary to the Anti-Corruption Laws caused by our controlling, controlled, affiliated or, under the respective contract, consortium companies, which could materially and adversely affect our reputation, business, financial condition and operating results, as well as impact the market price of our Securities negatively.

All of these circumstances could have a material adverse effect on us. Therefore, if we are not able to keep the governance, risk management and compliance processes operating effectively, we may not be able to prevent the occurrence of fraud and/or the occurrence of other deviations, including in relation to the preparation of statements and accounting information. We are actively collaborating with Ambipar ESG to enhance the effectiveness of our anti-money laundering and countering the financing of terrorism program ("AML/CFT Program") and our anti-bribery and corruption compliance program ("ABAC Program").

The existence of lawsuits, procedures, investigations, convictions, publications or negative comments in any media vehicle or social network involving us, our direct or indirect shareholders and subsidiaries, our business, our operations, executive officers, members of our Board, or any third party acting on our behalf, interest or benefit, could seriously damage our reputation. The reputational risk arising from the negative perception of our brand by customers, counterparties, shareholders, subsidiaries, investors, regulators and society in general for involvement in any of the above cases can originate from several factors, including those related to non-compliance with legal obligations, inappropriate business practices related to our customers, products and services, relationships with partners with questionable ethical posture, employee misconduct, information leakage, anti-competitive practices, failures in the risk management process, among others.

Any such damages to our reputation and imposition of sanctions or other penalties may adversely affect our business, financial condition and results of operations, as well as the market price of our Securities.

***Our results may be adversely impacted by incorrect estimates, judgments or assumptions relating to our critical accounting policies and changes in international financial reporting standards.***

The preparation of financial statements in conformity with IFRS requires our management to make estimates, judgments and assumptions that affect the amounts reported and disclosed in our Consolidated Financial Statements and accompanying notes. We base our estimates and assumptions on historical experience and on various other assumptions that we believe to be reasonable under the circumstances. The results of these estimates form the basis for making judgments about the carrying values of certain assets, liabilities, and equity, and the amount of revenue and expenses that are not readily apparent from other sources. Significant assumptions and estimates used in preparing our Consolidated Financial Statements and accompanying notes include those related to revenue recognition, fair value of certain assets and liabilities, share-based compensation, and income taxes, including any valuation allowance for deferred tax assets. Our results of operations may be adversely affected if our assumptions change or if actual circumstances differ from those in our assumptions, which could cause our results of operations to fall below the expectations of industry or financial analysts, which may result in a decline in the trading price of our Securities.

Additionally, the International Accounting Standard Board, or IASB, has a calendar for approving accounting pronouncements and IFRS, which may change at any time and over which we have no interference. Therefore, we are unable to predict which and when new accounting pronouncements or new IFRS rules will be approved that may in any way impact the future financial statements prepared by us.

We regularly monitor our compliance with applicable financial reporting standards and review new pronouncements and drafts thereof that are relevant to us. As a result of new standards, or changes and challenges to existing standards or their interpretation, we might be required to change our accounting policies, alter our operational policies or implement new or enhance existing systems so that they reflect new or amended financial reporting standards, or we may be required to restate our published financial statements. Such changes or challenges to existing standards or in their interpretation may have an adverse effect on our business, financial condition, and results of operations, or cause an adverse deviation from our revenue and operating profit and loss target, which may negatively impact our results of operations.

***Any increase in operational costs and any difficulties we encounter in recovering costs incurred by us for the performance of our activities may adversely affect us.***

The profitability of our services may be adversely affected by increases in the cost of food, wages and labor, insurance, fuel, acquisition and maintenance of equipment and machines, operating inputs, waste disposal, uniforms, PPE, medical assistance, transportation, tires, tolls, change in labor, social security and tax rates, public services and other essential items for the provision of services, particularly to the extent that we cannot recover this increase in costs through increases in the prices of our services due to general economic conditions, competitive conditions or contractual provisions with customers.

Operational costs for the performance of our activities have fluctuated significantly in recent years, and substantial increases in the cost of fuels and utilities have historically resulted in cost increases for our units. We may not be able to fully recover the increases in these costs, which could adversely affect our profitability.

[T](#ib885b07745664dce8cc23d0d35721f6b_7)[able](#ib885b07745664dce8cc23d0d35721f6b_7)[of](#ib885b07745664dce8cc23d0d35721f6b_7)[Contents](#ib885b07745664dce8cc23d0d35721f6b_7)

In addition, contractual, economic, competitive or market-specific conditions may limit our ability to increase the prices of our services. As a result of these factors, we may not be able to pass through any increases in costs to provide our services, improve operating margins and obtain adequate investment returns through price increases. We may also lose customers to lower-priced competitors and new competitors may enter our markets as we increase prices, directly impacting our financial balance.

***We may face potential conflicts of interest in negotiations with related parties.***

We generate revenues and incur costs and expenses in relation to related-party transactions, including under the Cost Sharing Agreement, as well as certain lease and loan agreements. These transactions can give rise to potential conflicts of interest. Conflicts of interest continue to be a significant area of focus for regulators, investors and the media. A failure to appropriately deal with these potential conflicts could negatively impact our reputation and result in potential litigation or regulatory action against us.

We cannot guarantee that our related person transaction policy and procedures is or will be effective to avoid potential conflicts of interest between us, our shareholders, members of our management and any related-parties, or that any such party has complied or will strictly comply with good governance practices and rules to deal with conflicts of interest. The perception of non-compliance with such requirements or policies could harm our reputation and adversely affect our business, financial condition and results of operations.

For additional information regarding transactions between related parties and our related person transaction policy, see "*Item 7.B. Major Shareholders and Related Party Transactions—Related Party Transactions*."

***We are a holding company and depend on the operational results of our subsidiaries.***

We are a holding company and therefore depend on the results of operations of our subsidiaries and controlled companies. Our ability to meet our debt service and other obligations depends not only on our cash flow generation, but also on the cash flow generation of our subsidiaries, controlled companies and their subsidiaries, and their ability to make cash available to us in the form of interest payments, equity, debt repayment and dividend distributions, among others.

Legal and contractual restrictions may limit our ability to obtain cash from our subsidiaries and controlled companies. If this limitation occurs, we may be unable to make the required payments of principal and interest on our debt instruments, or to honor our obligations. In addition, with respect to our Brazilian subsidiaries, the income tax exemption on the distribution of dividends provided for in the current Brazilian legislation may be amended, and dividends may be taxed in the future, adversely affecting us, given that taxes may be due on the distribution of dividends by our Brazilian subsidiaries.

Any adverse change in the business, financial condition or results of operations of our subsidiaries and controlled companies could adversely and materially affect our business, financial condition and results of operations.

***We may be liable for environmental, tax, labor and social security obligations of suppliers or service providers.***

We work with suppliers in various fields of activity and we cannot guarantee that such suppliers will be in full compliance with laws and regulations governing working conditions, environmental practices and sustainability, quarantine of the production chain and safety conditions, or that they will not use improper practices to reduce their costs, including corruption, money laundering or bribery. If any of our suppliers becomes involved in these practices, our reputation may be harmed and, as a result, our customers' perception of us may be adversely affected.

In some situations, we may be jointly liable for the acts of our suppliers. For example, we may be held jointly liable for environmental damages caused by our suppliers during the provision of services hired by us. In addition, under the Anti-Corruption Laws, we may be held strictly liable for acts of corruption committed by suppliers or other third parties acting on our behalf or interest, subject to applicable sanctions. Under the LGPD, we could also face liability for any incidents of personal data misuse committed by suppliers or third parties operating on our behalf or in our interest.

We may also be jointly and severally liable if our suppliers or third-party service providers do not comply with their obligations under the tax, labor, administrative, and social security laws and the regulations applicable to our industry, resulting in fines and other penalties that may affect us material and adversely. Further, we may be held liable for accidents within our or our customers' facilities involving third-party employees, which could adversely affect our reputation and our business. Any labor violations, environmental damage and/or damage to third parties caused by certain service providers in the exercise of activities contracted by us, mainly within our premises, may expose us to joint liability for the repair and/or indemnification of the damage caused, including the possibility of being included as a defendant in lawsuits aiming at repairing and/or indemnifying damages caused to workers, the environment and/or third parties. Depending on the involvement in the harmful event, we will also be exposed to administrative and criminal liability and to reputational risk, which could even prevent us from taking advantage of certain incentives and/or tax benefits, contracting with the government and/or causing the removal of our directors.

Any of such factors could adversely and materially affect our business, financial condition, results of operations and reputation, in addition to impacting the price of our Securities.

***The use and supply of outsourced labor may subject us to joint and several liability for labor and social security liabilities.***

We and our subsidiaries outsource certain ancillary activities that support our business, in addition to providing outsourced work to our customers. We do not provide benefits to these outsourced workers, who are paid directly by their employers. The use of outsourced labor subjects us to the risk that our relationship with these workers be considered an employment relationship by labor administrative and judicial authorities. In addition, according to Brazilian legislation, if our outsourced service providers fail to comply with their obligations under labor, social security, tax and/or environmental laws, we may be held jointly and severally or secondarily liable for their debts, including fines and/or other penalties, which may adversely affect us. We may also be liable for breaches of occupational health standards at our and our customers' facilities by the employees of third parties resulting from accidents or occupational diseases, which may adversely affect our reputation as well as our business. Further, any environmental damage and/or damage to third parties caused by service providers when undergoing work engaged by us expose us to joint and several liability for redress and/or damages for harm caused.

***Our operations may be affected by seasonal fluctuations and other demand factors over which we have no control.***

Demand for our services can be affected by the commencement and completion of cleanup of major spills and other events, customers' decisions to undertake remedial projects, seasonal fluctuations due to weather and budgetary cycles influencing the timing of customers' spending for remedial activities, the timing of regulatory decisions relating to hazardous waste management projects, changes in regulations governing the management of hazardous waste, changes in the waste processing industry towards waste minimization and the propensity for delays in the demand for remedial services, and changes in governmental regulations relevant to our diverse operations. Such impacts related to weather conditions could become more significant if climate change results in an increase in the frequency or severity of adverse weather events. We do not control such factors and, as a result, our revenue and income can vary from quarter to quarter or year to year, and past financial performance may not be a reliable indicator of future performance.

***Any failure to maintain long-term business relationships with our customers at the same or higher volumes or prices and/or to renegotiate such relationships on other favorable terms could negatively affect our ability to grow and adversely affect our competitiveness and our results of operations.***

We have developed long-term relationships with several customers and invest substantial amounts in machinery, equipment and specialized labor to comply with service agreements, with an average depreciation of 60 months of such machinery and equipment. If early termination occurs, for any reason, we could incur considerable losses.

------

[T](#ib885b07745664dce8cc23d0d35721f6b_7)[able](#ib885b07745664dce8cc23d0d35721f6b_7)[of](#ib885b07745664dce8cc23d0d35721f6b_7)[Contents](#ib885b07745664dce8cc23d0d35721f6b_7)

Under the terms of these agreements, customers can, at any time, unilaterally terminate the contracts they have entered into with us, materially reducing the amount of business that drives our revenue. There is no guarantee that we will be able to maintain or renew existing contracts, maintain relationships with our current customers or business partners or recover amounts owed by defaulting customers or business partners. In addition, we cannot guarantee that it will be possible to replace the revenue from these contracts, as they depend on various factors outside our control, including, among others, economic conditions in the industry, credit availability, general level of government financing for environmental activities, real estate development and other industrial investment opportunities. Increased competition could also require us to alter the pricing and terms we offer to our customer.

Accordingly, the loss of one or more of our customers or long-term business partners may adversely affect our business, financial condition and results of operations.

***Our business, financial condition and results of operations may be adversely affected by the various conflicting and/or onerous legal and regulatory requirements imposed on us by the countries where we operate.***

Our operations are subject to extensive federal, state and municipal environmental requirements, including those related to the transportation and disposal of regulated materials and cleaning up soil and groundwater contamination. In particular, in Brazil, we are subject to the provisions of the following environmental regulations: Federal Law No. 12,305/2010; CONAMA Resolution No. 358/2005; ABNT — NBR 13.221; ANTT nº 5232/2016, NBRs 7500, 7501, 7503, 9735, 14619, Decree No. 96044 and Statute No. 204 both issued by the Transportations Ministry NBR 10.004:2004; and IBAMA Normative Instruction No. 13/2012. We are also subject to extensive environmental requirements in other jurisdictions in which we operate, including in the United States under the Comprehensive Environmental Response, Compensation and Liability Act, the Resource Conservation and Recovery Act and the Oil Pollution Act.

We may not be able to fully comply with the legal and regulatory requirements to which we are subject. These legal and regulatory requirements may become more stringent in the future as a result of legislative and regulatory changes, which may cause us to incur unforeseen regulatory expenses. For example, we may need to incur additional costs to train employees and customers, purchase health and safety equipment and, in some cases, hire employees, external advisors and lawyers as a result of these changes.

The interpretation or application of existing laws and regulations, or the adoption of new laws and regulations, may require modifying or reducing our operations or replacing our facilities or equipment at a substantial cost, which we may not be able to pass onto our customers, which may negatively impact our results or may imply additional expenses in order to adapt our activities to these rules.

In addition, our industry is subject to extensive socio-environmental regulation. If the requirements imposed on our customers under federal or state laws and regulations for the handling of hazardous or radioactive waste are relaxed or applied less vigorously, the demand for our services may decrease significantly and our results of operations may be adversely affected. Conversely, if such requirements are made more stringent, certain of our customers' operations may be constrained or become subject to greater costs, and the demand for our services may consequently decrease significantly and our results of operations may be adversely affected.

***Failure to comply with socio-environmental laws and regulations, including with respect to the handling of hazardous waste, may adversely affect our business.***

We are subject to extensive foreign, Brazilian federal, state and municipal laws and regulations related to the adequate handling, transportation and disposal of hazardous or radioactive waste, the preservation and protection of the environment, the handling of dangerous products, as well as those related to occupational health and safety, the prohibition of labor analogous to slavery, to the use of child labor, to not encouraging prostitution and not employing foresters. Among other obligations, laws and regulations establish standards for the disposal of effluents, atmospheric emissions, solid waste management, minimum requirements for transporting waste, noise emission parameters, as well as requirements related to specially protected areas or species of organism.

[T](#ib885b07745664dce8cc23d0d35721f6b_7)[able](#ib885b07745664dce8cc23d0d35721f6b_7)[of](#ib885b07745664dce8cc23d0d35721f6b_7)[Contents](#ib885b07745664dce8cc23d0d35721f6b_7)

Any violations of socio-environmental laws and regulations may expose us to administrative and criminal penalties, in addition to the obligation to repair or indemnify damages caused to the environment and to third parties. In particular, the handling and transportation of hazardous waste services involve relevant environmental regulations, and any failure to comply with such regulations may adversely affect our ability to collect, process and finally dispose of hazardous waste generated by our customers. In case we are held liable for any losses or damages caused by the handling and transportation of hazardous waste, changes in environmental laws and regulations or in their interpretation could result in unforeseen changes to estimated timing and amounts for payment of such damages.

Some of these laws impose strict and, under certain circumstances, joint and several liability on current and former owners and operators of facilities that release regulated materials or that generate them and provide for their improper disposal or treatment. Such liability can also be imposed on certain other persons who release, transport, dispose of, or arrange for the disposal of hazardous substances. Such responsibilities may relate to the necessary cleaning of releases of regulated materials and the repair of environmental damage.

We are routinely inspected by government agencies, which may impose fines or other sanctions or require expenditures for remedial work. In addition, regulators have the power to suspend or revoke the permits for the operation of our facilities, equipment and vehicles based on, among other factors, our compliance record, and customers may decide not to use a specific installation of disposal or negotiate due to concerns about our compliance record. The suspension or revocation of permits would affect our operations and could have a material impact on our financial results.

Some environmental laws and regulations impose liability and responsibility on present and former owners, operators or users of facilities and sites for contamination at such facilities and sites without regard to causation or knowledge of contamination.

Any non-compliance and/or penalties applied within the scope of compliance with social and environmental legislation or any substantial capital expenditures made as a result of government proceedings may adversely impact our business, results, and our financial situation and reputation.

For more information about the environmental regulations to which we are subject, see "*Item 4.B. Information on the Company—Business Overview— Regulatory Overview*."

***We may incur increased costs arising from compliance with new or more restrictive social and environmental laws and regulations.***

Government agencies or other authorities, including environmental inspectors and control agents, may enact new stricter rules or seek more restrictive interpretations of existing socio-environmental laws and regulations. Environmental obligations, liabilities and conditions may also change depending on changes in the staff of the competent authorities, as well as in jurisprudence. As a result of any such changes, our investments and expenses necessary to comply with environmental legislation may increase substantially, which may require us to employ additional resources to adapt to the eventual new requirements of these agencies and environmental authorities. Any action in this regard by government agencies could adversely affect our business and have a material adverse effect on us. For more information about the environmental regulations to which we are subject, see "*Item 4.B. Information on the Company—Business Overview— Regulatory Overview*."

**Risks Relating to the Markets Where We Operate**

***Our international presence subjects us to a variety of risks arising from doing business internationally.***

As of December 31, 2024, we operated in 41 countries, having generated 41.9%, 46.3%, 5.6%, and 6.2% of our net revenues in North America, Brazil, Latin America (excluding Brazil) and Europe, respectively. In addition, as of December 31, 2024, 66% of our non-current assets other than financial instruments and deferred tax assets were located outside of Brazil. Our international footprint exposes us to a variety of risks that may adversely affect our results of operations, financial condition, liquidity and cash flows. These include, but may not be limited to, the following:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• periodic economic downturns in the countries in which we do business, measured by gross domestic product;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• foreign exchange fluctuation and imposition of or increases in currency exchange controls and hard currency shortages;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• customs matters and changes in trade policy or tariff regulations;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• changes in regulatory requirements in the countries in which we do business;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• changes in tax regulations, higher tax rates in certain jurisdictions and potentially adverse tax consequences including restrictions on repatriating earnings, adverse tax withholding requirements and "double taxation";

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• complexities around changes in the still developing relationship between the U.K. and the EU arising out of the U.K.'s withdrawal from the EU;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• longer payment cycles and difficulty in collecting accounts receivable;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• complexities in complying with a variety of Brazilian, U.S. and foreign government laws, controls and regulations;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• political, economic and social instability, including general strikes and mass demonstrations, civil and political unrest, transnational organized crime, terrorist actions and armed hostilities in the regions or countries in which, or adjacent to which, we do business;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• increasingly complex laws and regulations concerning privacy and data security, including the Brazilian LGPD, EU's GDPR and EU AI Act;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Varying degrees of anti-corruption or anti-money laundering legislation that could result in vulnerabilities within certain markets.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• inflation rates in the countries in which we do business;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• complying with complex labor laws in foreign jurisdictions;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• laws in various international jurisdictions that limit the right and ability of subsidiaries to pay dividends and remit earnings to affiliated companies unless specified conditions are met;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• sovereign risk related to international governments, including, but not limited to, governments stopping interest payments or repudiating their debt, nationalizing private businesses or altering foreign exchange regulations;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• uncertainties arising from local business practices, cultural considerations and international political and trade tensions;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• public health issues or other calamities impacting regions or countries in which we operate, including travel to and/or imports or exports to or from such regions or countries; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• other political, diplomatic, social and economic events that may occur in the country or affecting the country where each business is headquartered.

These risks may further increase as we continue to adopt our international expansion strategy. If we are unable to successfully manage the risks associated with our international business, our results of operations, financial condition, liquidity and cash flows may be negatively impacted.

***Governments have a high degree of influence in the economies of emerging markets where we operate, which could adversely affect our results of operations.***

Our operations in Brazil and Latin America (excluding Brazil) accounted, respectively, for 46.3% and 5.6% of our net revenues for the year ended December 31, 2024, and 36.1% and 7.3% of our net revenues for the year ended December 31, 2023. Governments in Latin America have exerted and continue to exert significant influence on the economy, occasionally making significant changes in monetary, credit, industry regulations and others. Government actions to control inflation and other policies and regulations often involve, among other measures, price controls, currency devaluations, capital controls and limits on imports.

[T](#ib885b07745664dce8cc23d0d35721f6b_7)[able](#ib885b07745664dce8cc23d0d35721f6b_7)[of](#ib885b07745664dce8cc23d0d35721f6b_7)[Contents](#ib885b07745664dce8cc23d0d35721f6b_7)

In particular, the Brazilian economy has suffered frequent interventions by the Brazilian federal government, which sometimes makes significant changes in its monetary, credit, tariff, tax and other policies and rules, in order to influence the Brazilian economy. Measures taken by the Brazilian federal government to control inflation, in addition to other policies and regulations, often involve raising interest rates, changing fiscal policies, controlling wages and prices, intervening in the foreign exchange market, currency devaluations, blocking access to bank accounts, controlling capital and limiting imports, among other measures.

In Chile, the government has changed in the past and has the ability to change monetary, fiscal, tax and other policies to influence the Chilean economy.

We have no control over, and cannot predict, what government measures or policies the Brazilian federal or other Latin American governments will take in the future, and how these measures and policies will affect the national and regional economy of Latin American countries. We may be materially and adversely affected by changes in policies or regulations that involve or affect certain factors, such as:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• interest rates;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• foreign exchange controls and restrictions on abroad remittances and payments of dividends;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• monetary policy;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• labor laws or jurisprudence positions;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• changing labor, legal and regulatory standards;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• data protection laws or regulations;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• intellectual property;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• inflation;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• liquidity and solvency of the financial system;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• liquidity of domestic financial and capital markets and availability of domestic loans;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• water and energy rationing;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• commodity prices;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• health policies, including due to epidemics and pandemics, such as the COVID-19 pandemic;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• fiscal policy, tax policy and changes in tax legislation, including royalties and the effect of tax laws on distributions from our subsidiaries;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• import/export restrictions or other laws and policies that affect foreign trade and investments;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• price controls or pricing regulations; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• takings or nationalization.

Uncertainty over the implementation of policy or regulatory changes by the Brazilian or other Latin American governments creates instability in the region's economy, increasing the volatility of its securities market. These uncertainties, the recession with a period of slow recovery and other future developments in the Brazilian and Latin American economy could adversely affect our business and, consequently, our financial condition and operating results, and could adversely affect the trading price of our Securities.

***Changes in U.S. Trade Policy Under the Trump Administration may adversely affect our result of operations***

Beginning on January 20, 2025, the Trump administration introduced significant alterations to existing trade policies, impacting global economic dynamics and creating both opportunities and challenges for international businesses. One notable shift was the implementation of reciprocal tariffs which introduced complexity and uncertainty for businesses reliant on global supply chains.

The administration also pursued renegotiations of existing trade agreements, such as those with Mexico and Canada, sometimes employing threats of tariffs as leverage. Furthermore, Trump continued to exert pressure on China through tariffs and other trade restrictions, contributing to broader trade tensions and disruptions in global markets.

As part of our global operations, we rely on access to international markets and supply chains to support our business expansion and operational efficiency. The trade policy changes implemented may adversely impact our ability to source key inputs at competitive prices, integrate newly acquired businesses, and execute our growth strategy. Higher import costs, retaliatory measures from key trading partners, and potential disruptions in supply chains could increase our operating expenses and affect the profitability of our business. Additionally, heightened trade tensions and regulatory uncertainty may create challenges for our mergers and acquisitions strategy, as they could affect valuations, transaction costs, and the ability to complete cross-border deals on favorable terms. If these policies persist or escalate, we may face increased risks in securing strategic acquisitions, maintaining cost efficiency, and sustaining our competitive position in the global market.

Beyond the direct impacts of the trade war, a significant risk stemmed from the uncertainty surrounding the administration's trade policy. The unpredictable nature of the measures taken, including fluctuating tariff threats and abrupt shifts in negotiating positions, made it challenging for businesses to plan effectively, forecast future performance, and make informed investment decisions. These uncertainties could adversely affect our business and, consequently, our financial condition and operating results, and could adversely affect the trading price of our Securities.

***Economic uncertainties and political instability in the Latin American countries in which we operate, in particular Brazil and Chile, may adversely affect our business, operations and financial condition and that of our subsidiaries.***

Countries in Latin America have experienced periods of economic and political instability in recent years. Unfavorable general economic conditions in the past, including the 2008 financial crisis that affected the global banking system and financial markets have caused economic slowdown and a decrease in the amount of foreign capital invested in emerging markets, including Latin America. This in turn has caused many emerging markets, including Latin America, to decline in value and has led to the depreciation of emerging market currencies against the U.S. dollar. As international investors' reactions to events that occur in one market sometimes affect other regions or disadvantage certain investments, the Latin American economy could be adversely affected by negative economic or financial developments in other countries, such as those related to the outbreak of COVID-19. Negative developments in Latin America or other emerging markets or developed economies could affect the decisions to hire service providers and the demand for the services offered by us, with a potential reduction in the number of customers.

According to the Brazilian Institute of Geography and Statistics (I*nstituto Brasileiro de Geografia e Estatística*, or "IBGE"), Brazil's gross domestic product ("GDP") sharply contracted by 4.1% in 2020 due to global effects of developments relating to the COVID-19 pandemic and grew by 2.9%, 2.9%, 3.4% in 2022, 2023 and 2024, respectively. Developments in the Brazilian economy may affect Brazil's growth rates and, consequently, the use of our products and services and we have been, and will continue to be, affected by changes in the Brazilian GDP.

In addition, Brazilian markets experienced heightened volatility in the last decade due to uncertainties deriving from investigations conducted by the Brazilian Federal Police and the Brazilian Federal Prosecutor's Office, including "Operação Lava Jato." Such investigations have impacted the Brazilian economy and political environment. Numerous members of the Brazilian federal government and the legislative power, as well as executives of large state owned, public and private companies, have resigned from their positions and/or been arrested or convicted, and others are still being investigated for allegations of unethical and illegal conduct identified during such investigations, including for accepting bribes through kickbacks in contracts awarded by the government to infrastructure, oil and gas, construction companies, among others. The amounts of these bribes allegedly financed political party campaigns and were not accounted for or publicly disclosed, serving to promote the personal enrichment of beneficiaries of the corruption scheme.

The ultimate outcome of this and other investigations is uncertain, but they had adversely affected the image and reputation of the implicated companies, as well as the market's general perception of the Brazilian economy. The development of these cases of unethical conduct has affected and may continue to adversely affect our business, financial condition and results of operations, as well as the trading price of our Securities. We cannot predict whether the ongoing investigations will lead to further political and economic instability, nor whether new allegations against government officials and executives or private companies will emerge in the future. We also cannot predict the results of these investigations, nor the impact on the Brazilian economy or the Brazilian stock market.

Any consequences of these investigations could materially and adversely affect the business environment in Brazil and our activities. Further political instability has been exacerbated by the Brazilian polarized presidential election held in October 2022. After having his criminal convictions related to Operação Lava Jato overturned and his political rights restored by the Brazilian Supreme Court, former Brazilian president Luiz Inácio Lula da Silva ran for office in the presidential election and narrowly defeated President Bolsonaro. Luiz Inácio Lula da Silva took office on January 1, 2023. In the aftermath of the November 2022 presidential election, there have been countrywide roadblocks and mass protests by supporters of former president Jair Bolsonaro disputing the election results, culminating, on January 8, 2023, in riots in the country's federal capital Brasilia where protesters stormed government buildings, including the Congress, the Supreme Court and the Presidential Palace. It is unclear whether this heightened state of political and social tension will dissipate or intensify in coming months and what resulting impacts may occur to adversely affect our business operations or the safety of our employees, our customers, and the communities in which we operate.

We cannot predict which policies the incoming president may adopt or change during his term in office, or the effect that any such policies might have on our business and on the Brazilian economy. Moreover, any difficulty experienced by the Brazilian federal government in obtaining a majority in the national congress could result in congressional deadlock, political unrest and massive demonstrations or strikes that could adversely affect our operations. Uncertainty over whether the Brazilian federal government will implement reforms or changes in policy or regulation affecting these or other factors in the future may affect economic performance and contribute to economic instability and increase the volatility of the Brazilian securities market.

We are also exposed to economic and political volatility in Chile. The Chilean economy has recently experienced a slowdown, and we cannot assure you that the Chilean economy will grow in the future or that future developments that affect the Chilean economy, including economic difficulties in Brazil, Argentina and other emerging markets or financial markets from developed economies, will not impair our ability to proceed with our Chilean operations.

Further, starting in October 2019, Chile began to experience social turmoil, initially because of a fare hike in Santiago's metro system. Student and civil protestors damaged public property and the private sector and disrupted institutions and commerce. The government initially declared a 90-day state of emergency, extendable as needed, and at the same time launched several political, social and economic reforms, and approved the calling of a national referendum. However, the state of emergency lasted less than ten days. On October 25, 2020, a constitutional referendum was held, in which about 80% of voters elected to replace the Chilean Constitution. The 2019 civil unrest led to the victory of left-wing Gabriel Boric in the December 2021 presidential elections. Mr. Boric was sworn in as president in March 2022. In September 2022, almost 62% of Chileans voted to reject the left-leaning draft of a new constitution proposed by the constituent assembly and backed by President Boric, which was perceived to be less market-friendly and to create legal uncertainty. There can be no assurance that the recent changes in the Chilean administration, its Constitution or any future civil unrest will not adversely affect our business, operating results and financial condition in Chile.

In general, emerging markets such as Brazil, Chile or other Latin American countries are also exposed to relatively higher risks of liquidity constraints, inflation, devaluation, price volatility, corruption, crime, asset expropriation and sovereign default, as well as additional legal and regulatory risks and uncertainties.

Economic uncertainty and political uncertainty in Brazil, Chile or other Latin American countries could materially and adversely affect the business environment in these countries and affect us disproportionately or differently than our competitors, depending on our specific exposure to any particular emerging market, which could have a material adverse effect on our business, operating income, financial condition and prospects.

***Political, economic and social events and the perception of risks in other countries, especially in emerging economy countries and in the United States, China and the European Union, may adversely affect the economy of the countries in which we operate and the market price of our Securities.***

Our Latin American operations may be affected, to varying degrees, by economic and market conditions in other countries, including the United States, European Union countries and other emerging economies. To the extent the conditions of the global markets or economy deteriorate, the business of companies with significant operations in Latin American countries may be harmed. For example, we are subject to impacts resulting from the current war between Ukraine and Russia and the recent escalating tensions in the region involving the Gaza Strip, Iran, Hezbollah in Lebanon and the Houthi in Yemen. The Ukraine war has caused market turmoil and led oil prices to soar, reaching the highest level in almost 14 years, thus affecting the market commodities and energy in Brazil and in the world, which could raise our operational costs and consumer expenses and, therefore, adversely affect our operational results and financial condition. In addition, an escalation in political tensions between the United States, Iran, Yemen, and Iraq, as well as other related conflicts in the Middle East, and imposition of additional sanctions from the United States, Iran, Iraq, and European countries could cause the price of oil to increase even further. Further, trade disputes between countries, in particular the current dispute between the United States and China, crises in the United States, the European Union or in emerging countries and global tensions, including conflicts involving the occurrence of Brexit, have generated political and economic instability around the world, producing several effects that, directly or indirectly, negatively impact the Latin American capital markets and economy, such as fluctuations in the price of securities issued by listed companies, reductions in the supply of credit, deterioration of the economy, fluctuations in foreign exchange rates and inflation, among others.

The weakness in the global economy has been marked by, among other adverse factors, lower levels of consumer and corporate confidence, decreased business investment and consumer spending, increased unemployment, reduced income and asset values in many areas, reduction of China's growth rate, currency volatility and limited availability of credit and access to capital, and, in early 2023, the crisis in global financial systems.

Given our exposure to Latin American economies, any such factors can reduce investor interest in our Securities. Developments, crises, political instability or economic conditions in other countries may significantly affect the perceptions of risks inherent to Latin America and the availability of credit to companies with significant operations in Latin America, which could result in considerable outflows of funds from Latin America and make it more difficult for us to access the capital markets and finance our operations in the future, on favorable terms or at all.

***Exchange rate instability can harm the economy of emerging markets where we operate and, consequently, affect us.***

The Latin American currencies have experienced in the past and are currently experiencing strong fluctuations against the dollar and other strong currencies.

In Brazil, over the past four decades, the federal government implemented various economic plans and used various foreign exchange policies, including sudden devaluations, periodic mini-devaluations (during which the frequency of adjustments has ranged from daily to monthly), floating exchange market systems, foreign exchange controls and the dual exchange market. Since 1999, Brazil has adopted a floating foreign exchange system with Central Bank interventions in the purchase or sale of foreign currency. From time to time, there have been significant foreign exchange rate fluctuations between the real and the dollar and other currencies.

Although long-term depreciation of the real is generally linked to the rate of inflation in Brazil, depreciation of the real occurring over shorter periods of time has resulted in significant variations in the exchange rate between the real, the U.S. dollar and other currencies. The real/U.S. dollar exchange rate reported by the Central Bank was R$5.218 per US$1.00 on December 31, 2022. As of December 31, 2023, the average real/U.S. dollar exchange rate reported by the Central Bank was R$5.00 per US$1.00, which reflected a 3.3% appreciation of the real against the U.S. dollar during 2023. As of December 31, 2024, the real/U.S. dollar exchange rate reported by the Central Bank was R$5.392 per US$1.00, which reflected a 7.9% depreciation in the real against the U.S. dollar during 2024. There can be no assurance that the real will not further appreciate or again depreciate against the U.S. dollar or other currencies in the future.

The devaluation of the real and other Latin American currencies relative to the U.S. dollar could create additional inflationary pressures in Brazil and Latin America and lead to increases in interest rates. Any depreciation of these currencies may generally restrict access to the international capital markets. It would also reduce the U.S. dollar value of our results of operations. Restrictive macroeconomic policies could reduce the stability of the Brazilian and Latin American economy and harm our results of operations and profitability. In addition, domestic and international reactions to restrictive economic policies could have a negative impact on the Brazilian and Latin American economy. These policies and any reactions to them may harm us by curtailing access to foreign financial markets and prompting further government intervention. A devaluation of Latin American currencies relative to the U.S. dollar may also, as in the context of the current economic slowdown, decrease consumer spending, increase deflationary pressures and reduce economic growth, which could negatively affect the economy of Latin American countries as a whole and our results, due to the contraction in consumption and the increase in its costs.

On the other hand, the appreciation of the Latin American currencies relative to the U.S. dollar and other foreign currencies could lead to the deterioration of the region's current accounts and balance of payments, as well as a weakening in the growth of the gross domestic product generated by exports. It could also have an adverse impact in our financial condition and results of operations due to translation risk.

We do not exercise any influence on the exchange policy adopted in Brazil or other Latin American countries, nor do we have the capacity to predict it. Our business, financial condition, results of operations and prospects could be negatively affected by changes in such foreign exchange rate policies.

***Inflation and government efforts to curb it may contribute to an uncertain economic scenario, adversely affecting us and the market price of our Securities.***

General inflation, including rising prices for energy and other inputs as well as rising wages may negatively impact our business by increasing our operating costs. The cost of materials, fuel, labor and other components of our operating costs used in our services are affected by inflation and global commodity prices. We may mitigate this risk through passing along price increases to our customers. However, we may not always be able to raise prices in response to increased costs or may experience delays in passing through such costs, as our ability to do so is largely dependent upon market conditions and competitive market pressures. These inflationary cost pressures have resulted and may result in reductions in our operating margins and cash flows in the future.

General inflation in the United States, Europe and other geographies has risen to levels not experienced in recent decades. These concerns have resulted in an increase of interest rates and the respective governments and institutions taking and contemplating other measures to curb inflation, which in turn has negatively impacted the capital markets generally.

Latin American countries have historically experienced high rates of inflation from time to time, which have, together with certain actions taken by the Latin American government in an attempt to curb inflation and speculation about what measures would be adopted, negative effects on the Latin American countries economy and contributed to economic uncertainty, increasing the volatility of the Latin American capital markets.

[T](#ib885b07745664dce8cc23d0d35721f6b_7)[able](#ib885b07745664dce8cc23d0d35721f6b_7)[of](#ib885b07745664dce8cc23d0d35721f6b_7)[Contents](#ib885b07745664dce8cc23d0d35721f6b_7)

In Brazil, according to the National Consumer Price Index (*Índice Nacional de Preços ao Consumidor Amplo*, or IPCA), which is published by the IBGE, Brazilian inflation rates were 4.83%, 4.62%, 5.79%, 10.06%, 4.52%, and 4.31% as of December 31, 2024, 2023, 2022, 2021 2020 and 2019, respectively. While inflation rates slowdown in recent years, Brazil may experience high levels of inflation in the future and may lead to the Brazilian government's intervening in the economy and introducing policies that could harm our business and the price of our Securities. In the past, the Brazilian government's interventions included the maintenance of a restrictive monetary policy with high interest rates that restricted credit availability and reduced economic growth, causing volatility in interest rates. The Monetary Policy Committee (*Comitê de Política Monetária do Banco Central do Brasil*, or COPOM) frequently adjusts the interest rate in situations of economic uncertainty to achieve goals established in the Brazilian federal government's economic policy. In the event of an increase in inflation, the Brazilian federal government may choose to significantly increase interest rates. For example, the official interest rate in Brazil oscillated from 14.25% as of December 31, 2015 to 2.00% as of December 31, 2020, as established by the COPOM, and since then it has remained at a higher level. As of December 31, 2021, 2022, 2023 and 2024, the SELIC rate was 9.25% p.a., 13.75% p.a., 11.75% p.a., 12.25% p.a. respectively. As of the date of this annual report, the SELIC rate is 15.00% p.a. The increase in interest rates will affect not only the cost of our new loans and financing, but also the cost of our current debt, as well as our cash and cash equivalents, securities and payable leases, which are subject to interest rates.

In Chile, the annual rates of inflation, measured by changes in the CPI, in 2022, 2023 and 2024 were 12.8%, 3.9% and 4.5%, respectively. Higher levels of inflation in Chile could adversely affect the Chilean economy and have an adverse effect on our results of operations if high inflation is not accompanied by a corresponding devaluation of the local currency. It is not possible to guarantee or predict that Chilean inflation will not revert to previous levels in the future. In addition, measures taken by the Central Bank of Chile to control inflation often included maintaining a tight monetary policy with high interest rates, thus restricting the availability of credit and economic growth. A significant portion of our operating costs are denominated in U.S. dollars and could, therefore, be significantly affected by a decrease in economic activity levels in Chile. If inflation in Chile increased without a corresponding depreciation of the peso, or if the amount of the peso appreciated against the dollar without the peso experiencing a corresponding deflation in Chile, our financial position and operating results, as well as the value of our Securities, could be materially and adversely affected.

Any fluctuations in interest rates and measures taken by the U.S., EU, Latin American and other governments in the future, including reducing interest rates, intervening in the foreign exchange market and implementing mechanisms to adjust or determine currency amount, could trigger inflation, adversely affecting the overall performance of global and national economies. If the countries where we operate experience higher inflation in the future, we may not be able to adjust the prices we charge our customers to offset the effects of inflation on their cost structure, which will increase our costs and reduce our operating and net margins.

***Our operating results may be impacted by changes in tax legislation, unfavorable results from tax contingencies or by the modification, suspension or cancellation of tax benefits or special regimes.***

Latin American tax authorities regularly implement changes in the tax regime that could affect us. These measures include changes in current rates and, occasionally, the creation of temporary and permanent taxes. Some of these changes may increase, directly or indirectly, our tax burden, which may increase the prices we charge for our services, restrict our ability to do business and, therefore, materially and adversely impact our business and results of operations. In addition, certain tax laws may be subject to controversial interpretations by tax authorities. If tax authorities interpret tax laws in a manner inconsistent with our interpretations, we may be adversely affected, including by the full payment of taxes due, plus charges and penalties.

The Brazilian tax reform on consumption taxes was approved by the Brazilian Congress and is now expected to come into effect gradually between 2027 and 2032, pending the resolution of certain administrative matters. Nonetheless, Brazilian legislators continue debating a comprehensive tax reform, focused on income tax legislation, which may include an increase in existing taxes and contribution rates, the revocation of income tax exemptions on the distribution of profits and dividends and further changes relating to interest on net equity. The approval of these legislative proposals or changes in fiscal policies, tax laws and interpretations may impact our tax obligations and may have a material adverse effect on our financial condition and results of operations, and on the market value of our Securities.

In Chile, over the past decade, several substantial changes have been made to the income tax system, including increases in corporate and personal income tax rates. In February 2020, the Chilean Congress passed Law No. 21,210 (the "2020 Chilean Tax Reform"), including several amendments to the Chilean tax system. Among these amendments, the 2020 Chilean Tax Reform provides for (i) the elimination, effective from January 1, 2020, of the coexistence of the attributed income tax system and the consolidation of a partially integrated single tax system for large companies, which was created in 2014, with an income tax rate of 27%, (ii) the creation of a new special tax regime for small and medium-sized companies, with an income tax rate of 25% that can be fully integrated into final taxes, (iii) phasing out the tax refunds that Chilean holding companies could claim for corporate taxes paid by their Chilean subsidiaries as a result of absorbing the holding companies' tax losses with dividends received from such subsidiaries, (iv) increasing the maximum rate of taxes to 40% for personal income tax applicable to resident individuals, (v) application of VAT to foreign digital services used in Chile and (vi) stricter requirements for private investment funds to benefit from preferential tax treatment. Based on Chile's current social and political environment following the civil unrest that began in October 2019, the Chilean government may introduce further tax reforms aimed at limiting tax exemptions and/or preferential tax treatments. The 2020 Chilean Tax Reform and the interpretation of the RSI (the Chilean tax authority), or the potential approval of future tax reforms, may have other consequences for us, and there can be no guarantee that the current tax burden will not be adjusted in the future to finance future social reforms promoted by the Chilean government or to achieve other purposes.

Further changes in the tax laws of the jurisdictions in which we operate could arise as a result of the base erosion and profit shifting project being undertaken by the OECD. The OECD, which represents a coalition of member countries that includes Chile, Colombia and the United States, has undertaken studies and is publishing action plans that include recommendations aimed at addressing what they believe are issues within tax systems that may lead to tax avoidance by companies. The OECD has extended inclusion to non-OECD countries under their Inclusive Framework on Base Erosion and Profit Shifting, or BEPS, bringing together over 100 countries to collaborate on the implementation of the OECD BEPS Package. This framework allows interested countries and jurisdictions to work with the OECD and G20 members on developing standards on BEPS-related issues and reviewing and monitoring the implementation of the whole BEPS Package. Included within this expanded group of countries are several additional jurisdictions in which we do business. It is possible that the additional jurisdictions in which we do business could react to these initiatives or their own concerns by enacting tax legislation that could adversely affect us or our shareholders through increasing our tax liabilities.

Besides changes in tax legislation, we are subject to inspections by tax authorities at the various jurisdictions in which we operate. As a result of such inspections, our tax positions may be questioned by the tax authorities, which can result in legal and administrative proceedings. For example, Brazilian tax authorities regularly inspect companies and have recently intensified the number of inspections they conduct, showing particular concern for certain matters such as inventory control, goodwill amortization expenses, corporate restructuring and tax planning, among others. Any legal and administrative proceedings relating to tax matters may adversely affect us. We cannot guarantee that the provisions for any tax proceedings will be correct, that there will be no identification of additional tax exposure, and that it will not be necessary to establish additional tax reserves for any tax exposure. Any increase in the amount of taxation as a result of challenges to tax positions could adversely affect our business, results of operations and financial condition.

***Any further decline in Brazil's credit rating could adversely affect the trading price of our Securities.***

We may be adversely affected by investors' perception of risks related to the credit rating of Brazil's sovereign debt. Risk rating agencies regularly assess Brazil and its sovereign risk scores, which are based on a number of factors, including macroeconomic trends, fiscal and budgetary conditions, debt metrics and the prospect of changes in any of these factors.

In September 2015, Standard & Poor's initiated a review of Brazil's sovereign credit risk rating, downgrading it to a grade below "investment grade." Brazil has suffered successive downgrades in its rating by the three major risk rating agencies in the world in the past years. Recently Moody's upgraded Brazil's sovereign rating credit from Ba2 to Ba1, positive outlook, but on May 30, 2025, changed the outlook from positive to stable. As of the date of this annual report, Standard & Poor's, Moody's and Fitch rated Brazil's sovereign credit rating as BB stable, Ba1 stable and BB stable, respectively.

Continuing or worsening of the current Brazilian recession and continued political uncertainty, among other factors, could lead to further downgrades. We cannot guarantee that credit bureaus will maintain these ratings on Brazilian credit. Any further downgrade of Brazil's sovereign credit ratings could increase investors' perception of risk and, as a result, negatively affect the price of our Securities.

***Changes in legislation and regulations in Chile may have an adverse effect on our business.***

Our Chilean subsidiaries are subject to a certain set of Chilean laws and regulations, and there can be no assurance that such laws and regulations will remain unchanged. Changes in legislation, whether due to the repeal of existing legislation, the imposition of additional regulation, the enactment of new applicable legislation or changes in official interpretations of existing rules by the competent authorities, may affect our Chilean subsidiaries' way of conducting their business and may have an adverse effect on our business.

In the past, the Chilean government has modified, and has the ability to modify laws, monetary, fiscal, tax and other policies to influence the Chilean economy. We have no control over government policies and cannot predict how government intervention will affect the Chilean economy or, directly and indirectly, our business, results of operations and financial condition. For example, as part of the COVID-19 economic and financial aid package promulgated by the Chilean Congress, from July 2020 to April 2021, three laws (Law No. 21,248; Law No. 21,295; and Law No. 21,330) were passed to allow affiliates of the private pension system governed by Decree Law No. 3,500, to withdraw funds (up to 10% each time, subject to certain limitations) from their personal pension funds accounts.

Industry laws and regulations change at the national, regional and local levels, and these changes can impose costs and other difficulties that can prevent our Chilean subsidiaries from properly developing their business and achieving expected results. In addition, any change in regulation, the interpretation of existing regulations, the imposition of additional regulations or the enactment of new legislation that affects any of the companies could have an adverse impact, directly or indirectly, on the financial condition and results of operations.

For example, there have been some legislative efforts in labor matters that could affect the operational costs of our Chilean subsidiaries. For instance, there are several bills under discussion to shorten the work week from 5-6 days to 4 days a week, and from 45 hours to 40-38 weekly hours, with no salary decrease. There is also discussion to force companies to distribute among eligible employees, between 8% to 15% of a company's profits (depending on the company's size), subject to certain limits. Likewise, the minimum wage was recently increased to Ch$350,000/month under a government plan that intends to gradually increase it to up to Ch$500,000/month. These changes, and other that may arise in the future, could impact labor costs associated with our operations and affect our income.

***A severe earthquake or tsunami in Chile could negatively affect the Chilean economy and our facilities and, as a result, negatively impact our business, financial condition and consolidated operating results.***

Chile is on the Nazca tectonic plate, one of the most seismically active regions in the world. Chile has been adversely affected by powerful earthquakes in the past, including a magnitude 8.8 Richter scale earthquake in south-central regions in 2010, and a magnitude 8.3 Richter Scale earthquake in northern Chile in 2014 that caused several blackouts due to damage to the local electricity distribution network, and a magnitude 8.4 Richter Scale earthquake in northern Chile in 2015. An earthquake of magnitude 9.5 Richter Scale occurred in Valdivia, Chile, in 1960, which remains the largest recorded earthquake in modern history.

A severe earthquake or tsunami in Chile could damage our facilities and have an adverse impact on the Chilean economy and us, including our business, financial condition and consolidated operating results. Our facilities are also susceptible to damage from fire and other catastrophic disasters arising from natural or man-made accidental causes, as well as acts of terrorism and health pandemics or other contagious outbreaks. A catastrophic event could cause disruption to our business, significant reductions in our revenues or significant additional costs.

***Under a constitutional provision, the Chilean government has the power to seize or expropriate our assets under certain circumstances.***

Pursuant to Article 19 No. 24 of the Chilean Constitution, the Chilean government may exercise its eminent domain powers over our assets, if the government considers the action required in order to protect public interests. According to Decree-Law (Decreto con Fuerza de Ley) No. 2186 of 1978, eminent domain powers can be exercised through a process of administrative expropriation, the result of which can be appealed to a civil court. In the event of expropriation, we would be entitled to compensation for the expropriated assets. However, the offset may be less than the price at which the expropriated asset could be sold in an open market sale or the asset's value as part of an ongoing deal.

**Risks Relating to Our Securities**

***The market price and trading volume of our Securities have been and may be continue to be extremely volatile and could decline significantly.***

The price of our Class A Ordinary Shares, as well as the price of our Warrants, have been and may continue to be extremely volatile in the future. Our Class A Ordinary Shares and Warrants began trading on the NYSE American on March 6, 2023 and as such, are newly listed, have a limited public float and a short trading history to date. For instance, on March 14, 2023, the Class A Ordinary Shares experienced an intra-day trading high of $22.24 per share and a low of $5.37 per share. In addition, from March 6, 2023 to May 11, 2023, the closing price of Class A Ordinary Shares on the NYSE American ranged from as low as $5.26 to as high as $25.35 and daily trading volume ranged from 9,129 to 8,383,749 shares. Likewise, on the same period, the closing price of our Warrants on the NYSE American ranged from as low as $0.31 to as high as $0.72 and daily trading volume ranged from 100 to 248,265 Warrants. In the last twelve months as of the date of this report, AMBI shares ranged from as low as $3.22 to as high as $8.20. During this time, we have not experienced any material changes in our financial condition or results of operations that would explain such price volatility or trading volume. These broad market fluctuations may adversely affect the trading price of the Class A Ordinary Shares and Warrants.

Factors affecting the trading price of our Securities may include, without limitation:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• actual or anticipated fluctuations in our consolidated quarterly financial results or the quarterly financial results of companies perceived to be similar to it;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• changes in the industries in which we and our customers operate;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• developments involving our competitors;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• variations in our operating performance and the performance of our competitors in general;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• changes in the market's expectations about our operating results;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• our operating results failing to meet market expectations in a particular period;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• operating and stock price performance of other companies that investors deem comparable to us;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• publication of research reports by securities analysts about us or our competitors or our industry;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• the public's reaction to our press releases, our other public announcements and filings with the SEC;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• actions by shareholders, including the sale of substantial amounts of our Ordinary Shares by our directors, executive officers or significant shareholders or the perception that such sales could occur;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• "short squeezes;"

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• our ability to integrate and retain key personnel, identify and recruit additional key individuals, and manage additions and departures of key personnel;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• commencement of, or our involvement in, litigation;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• our ability to enhance our acquisition strategies;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• changes in laws and regulations affecting our business;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• our ability to meet compliance requirements;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• changes in our capital structure, such as future issuances of securities or the incurrence of additional debt;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• the volume of our Class A Ordinary Shares available for public sale;

------

[T](#ib885b07745664dce8cc23d0d35721f6b_7)[able](#ib885b07745664dce8cc23d0d35721f6b_7)[of](#ib885b07745664dce8cc23d0d35721f6b_7)[Contents](#ib885b07745664dce8cc23d0d35721f6b_7)

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• any significant change in our Board or management; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• general economic and political conditions such as recessions or fear of recessions, interest rates, unemployment levels, conditions in the housing market, immigration policies, government shutdowns, trade wars, fuel prices, international currency fluctuations, delays in tax refunds, as well as events such as natural disasters, acts of war (including the recent conflict in Ukraine), terrorism, catastrophes and pandemics.

These and other external factors, some of which are beyond our control, may have caused and may continue to cause the market price and demand for the Class A Ordinary Shares and Warrants to fluctuate substantially. Any of such factors could have a material adverse effect on your investment in our Securities, and our Securities may trade at prices significantly below the price you paid for them, which may limit or prevent you from readily selling your Securities and may otherwise negatively affect the liquidity of the Class A Ordinary Shares and Warrants. In such circumstances, the trading price of our Securities may not recover and may experience a further decline.

Broad market and industry factors may materially harm the market price of our Securities irrespective of our operating performance. The stock market in general, and the NYSE American in particular, have experienced price and volume fluctuations that have often been unrelated or disproportionate to the operating performance of the particular companies affected. The trading prices and valuations of these stocks, and of our Securities, may not be predictable. A loss of investor confidence in the market for emergency response or the stocks of other companies which investors perceive to be similar to us could depress the trading price of our Securities and our business, prospects, financial conditions or results of operations. A decline in the market price of our Securities also could adversely affect our ability to issue additional securities and to obtain additional financing in the future.

***A "short squeeze" due to a sudden increase in demand for our Class A Ordinary Shares that largely exceeds supply may lead to extreme price volatility in our Class A Ordinary Shares.***

Investors may purchase our Class A Ordinary Shares to hedge existing exposure or to speculate on the price of our Class A Ordinary Shares. Speculation on the price of our Class A Ordinary Shares may involve long and short exposures. To the extent aggregate short exposure exceeds the number of the Class A Ordinary Shares available for purchase on the open market, investors with short exposure may have to pay a premium to repurchase the Class A Ordinary Shares for delivery to lenders of the Class A Ordinary Shares. Those repurchases may in turn dramatically increase the price of the Class A Ordinary Shares until additional Class A Ordinary Shares are available for trading or borrowing. This is often referred to as a "short squeeze." A short squeeze could lead to volatile price movements in the Class A Ordinary Shares that are unrelated or disproportionate to our financial condition, results of operations or our future prospects and, once investors purchase the Class A Ordinary Shares necessary to cover their short positions, the price of the Class A Ordinary Shares may rapidly decline. Shareholders that purchase the Class A Ordinary Shares during a short squeeze may lose a significant portion of their investment.

***Subject to the terms and conditions of the Warrant Agreement, our Warrants are exercisable for our Class A Ordinary Shares, which may increase the number of shares eligible for future resale in the public market and result in dilution to our shareholders, and adversely affect the market price of our Class A Ordinary Shares.***

Outstanding Warrants to purchase up to 16,180,000 of our Class A Ordinary Shares are exercisable at a price of $11.50 per share. As long as we have an effective registration statement covering the issuance of the Class A Ordinary Shares issuable upon exercise of the Public Warrants, the Public Warrants may only be exercised for cash. The Private Warrants may be exercised on a "cashless" basis by the Sponsor or its permitted transferees and on the same basis as the Public Warrants if held by holders other than the Sponsor or its permitted transferees.

------

[T](#ib885b07745664dce8cc23d0d35721f6b_7)[able](#ib885b07745664dce8cc23d0d35721f6b_7)[of](#ib885b07745664dce8cc23d0d35721f6b_7)[Contents](#ib885b07745664dce8cc23d0d35721f6b_7)

To the extent such Warrants are exercised, additional Class A Ordinary Shares will be issued, which will result in dilution to the existing holders of our Class A Ordinary Shares and increase the number of our shares eligible for resale in the public market. We believe the likelihood that warrant holders will exercise their Warrants, and therefore the amount of cash proceeds that we would receive, is dependent upon the trading price of our Class A Ordinary Shares. If the trading price for our Class A Ordinary Shares is less than $11.50 per share, we believe warrant holders will be unlikely to exercise their Warrants on a cash basis. On June 23, 2025, the last reported sales price of our Class A Ordinary Shares was $4.46 per share and the last reported sales price of our Warrants was $0.15 per warrant. Sales of substantial numbers of such shares in the public market or the fact that such Warrants may be exercised could adversely affect the market price of our Class A Ordinary Shares. However, there is no guarantee that the Warrants will ever be in the money prior to their expiration, and as such, our Warrants may expire worthless.

***We may issue additional Class A Ordinary Shares from time to time, including under our Omnibus Incentive Plan or in connection with equity or convertible debt offerings to finance our growth and implementation of our business strategy. Any such issuances would dilute the interest of our shareholders and likely present other risks.***

We may issue additional Class A Ordinary Shares from time to time, including under our Omnibus Incentive Plan. Class A Ordinary Shares reserved for future issuance under our Omnibus Incentive Plan will become eligible for sale in the public market once those shares are issued, subject to provisions relating to time-based and performance-based vesting conditions, lock-up agreements and, in some cases, limitations on volume and manner of sale applicable to affiliates under Rule 144, as applicable. We have filed a registration statement on Form S-8 under the Securities Act to register the issuance of up to approximately 1.1 million Class A Ordinary Shares issuable under the Omnibus Incentive Plan. In addition, on July 3, 2024, we filed registration statements on Form S-8 under the Securities Act to register an additional 953,403 Class A Ordinary Shares or securities convertible into or exchangeable for Class A Ordinary Shares issued pursuant to our Omnibus Incentive Plan, as amended and restated on July 22, 2024. Any future Form S-8 registration statements will automatically become effective upon filing. Accordingly, shares registered under such registration statements may be immediately available for sale in the open market.

We may also issue additional Class A Ordinary Shares from time to time in connection with equity or convertible debt offerings to finance our growth and implementation of our business strategy, including as part of an acquisition. Because our decision to issue additional equity or debt securities in the future will depend on market conditions and other factors beyond our control, we cannot predict or estimate the amount, timing, nature or success of our future capital raising efforts. As a result, future capital raising efforts may reduce the market price of Class A Ordinary Shares and be dilutive to existing shareholders. In addition, our ability to raise additional capital through the sale of equity or convertible debt securities could be significantly impacted by substantial sale of our Securities by securityholders, which could result in a significant decline in the trading price of our Class A Ordinary Shares and potentially hinder our ability to raise capital at terms that are acceptable to us or at all. In addition, a significant decline in the trading price of our Class A Ordinary Shares could potentially impact our ability to use equity securities as consideration in acquisitions or as a potential source of liquidity for future growth.

***We incur increased costs as a result of becoming a public company in the United States***.

As a public company in the United States that qualifies as a foreign private issuer, we are subject to certain of the reporting requirements of the Exchange Act and the Sarbanes-Oxley Act and other requirements by the NYSE American. The Exchange Act requires the filing of annual reports on Form 20-F and current reports on Form 6-K with respect to a public company's business and financial condition. Rules promulgated under the Exchange Act also require us to make detailed narrative and financial statement disclosures regarding risks, initiatives and other matters confronting us relating to climate change, beginning as early as 2026. The Sarbanes-Oxley Act requires, among other things, that a public company establish and maintain effective internal control over financial reporting.

------

[T](#ib885b07745664dce8cc23d0d35721f6b_7)[able](#ib885b07745664dce8cc23d0d35721f6b_7)[of](#ib885b07745664dce8cc23d0d35721f6b_7)[Contents](#ib885b07745664dce8cc23d0d35721f6b_7)

As a result of these rules and regulations, we incur substantial legal, accounting and financial compliance costs. These laws, regulations and standards are subject to varying interpretations, in many cases due to their lack of specificity, and, as a result, their application in practice may evolve over time as new guidance is provided by regulatory and governing bodies. This could result in continuing uncertainty regarding compliance matters, higher costs necessitated by ongoing revisions to disclosure and governance practices and a diversion of management's time and attention from revenue generating activities to compliance activities. Additionally, these rules and regulations will likely make it more difficult and more expensive for us to obtain director and officer liability insurance, and we may be required to accept reduced policy limits and coverage or incur substantially higher costs to obtain the same or similar coverage. As a result, it may be difficult for us to attract and retain qualified people to serve on our Board, our Board committees or as executive officers.

In addition to the above, the compliance with these requirements have increased, and will continue to increase, our legal and financial compliance costs. Our management team and many of our other employees and independent contractors need to devote substantial time to compliance. Many members of our management team also have limited experience managing a publicly traded company, interacting with public company investors and complying with the increasingly complex laws pertaining to public companies. The additional demands associated with being a public company may disrupt regular operations of our business by diverting the attention of some of our senior management team away from revenue producing activities to management and administrative oversight, adversely affecting our ability to attract and complete business opportunities and increasing the difficulty in both retaining professionals and managing and growing our businesses Our management team may not successfully or efficiently manage a public company subject to significant regulatory oversight and reporting obligations under the federal securities laws and regulations and the continuous scrutiny of securities analysts and investors.

We have made, and will continue to make, changes to our financial management control systems and other areas to manage our obligations as a public company in the United States, including corporate governance, corporate controls, disclosure controls and procedures and financial reporting and accounting systems. Implementation of such changes is an ongoing, costly, time-consuming and, even if implemented, may not be sufficient to allow us to satisfy our obligations as a public company on a timely basis. Any delay could impact our ability or prevent us from timely reporting our operating results or timely filing reports with the SEC. The development and implementation of the standards and controls necessary for us to achieve the level of accounting standards required of a public company in the United States may require costs greater than expected. We may need to significantly expand our employee and independent contractor base in order to support our operations as a public company, increasing our operating costs. Any failure to implement required new or improved controls, or difficulties encountered in their implementation, could cause us to fail to meet our reporting obligations. Ineffective internal controls could also cause investors to lose confidence in our reported financial information, which could negatively affect the trading price of our Securities.

As a result of disclosure of information in this annual report and in filings required of a public company, our business and financial condition has become more visible, which could result in threatened or actual litigation, including by competitors and other third parties. If such claims are successful, our business and operating results could be adversely affected, and, even if the claims do not result in litigation or are resolved in our favor, these claims, and the time and resources necessary to resolve them, could cause an adverse effect on our business, financial condition, results of operations, prospects and reputation.

***We are and will continue to be an "emerging growth company" and are subject to reduced SEC reporting requirements applicable to emerging growth companies.***

We are an "emerging growth company" as defined in Section 2(a)(19) of the Securities Act, as modified by the JOBS Act. As such, we will be eligible for and intend to take advantage of certain exemptions from various reporting requirements applicable to other public companies that are not emerging growth companies for as long as we continue to be an emerging growth company, including the exemption from the auditor attestation requirements with respect to internal control over financial reporting under Section 404(b) of the Sarbanes-Oxley Act, (and, to the extent we cease to be a foreign private issuer but remain an emerging growth company, we would remain able to take advantage of (a) the exemptions from say-on-pay, say-on-frequency and say-on-golden parachute voting requirements and (b) reduced disclosure obligations regarding executive compensation in its periodic reports and proxy statements). We will remain an emerging growth company until the earliest of (i) the last day of the fiscal year in which the market value of our Securities that are held by non-affiliates exceeds $700 million as of June 30 of that fiscal year, (ii) the last day of the fiscal year in which we have total annual gross revenue of $1.235 billion or more during such fiscal year (as indexed for inflation), (iii) the date on which we have issued more than $1 billion in non-convertible debt in the prior three-year period or (iv) the last day of the fiscal year following the fifth anniversary of the Closing of the Business Combination. In addition, Section 107 of the JOBS Act provides that an emerging growth company can take advantage of the exemption from complying with new or revised accounting standards provided in Section 7(a)(2)(B) of the Securities Act as long as it is an emerging growth company. An emerging growth company can therefore delay the adoption of certain accounting standards until those standards would otherwise apply to private companies. We have elected not to opt out of such extended transition period and, therefore, we may not be subject to the same new or revised accounting standards as other public companies that are not emerging growth companies. Investors may find our Ordinary Shares less attractive because we will rely on these exemptions, which may result in a less active trading market for our Ordinary Shares and its price may be more volatile.

***We are a "controlled company" within the meaning of the rules of the NYSE American. As a result, we qualify for exemptions from certain corporate governance requirements that would otherwise provide protection to shareholders of other companies.***

Ambipar controls a majority of the voting power of our Ordinary Shares. As a result, we are a "controlled company" within the meaning of the corporate governance standards of the NYSE American. Under these rules, a company of which more than 50% of the voting power is held by an individual, group or another company is a "controlled company" and may elect not to comply with certain corporate governance requirements, including:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• the requirement that a majority of its Board consist of independent directors;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• the requirement that the nominating and corporate governance committee is composed entirely of independent directors; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• the requirement that the compensation committee is composed entirely of independent directors.

Currently, we do not plan to utilize the exemptions available for controlled companies, but are relying on the exemption available for foreign private issuers to follow our home country governance practices instead. If we cease to be a foreign private issuer or if we cannot rely on our home country governance practice exemption for any reason, we may decide to invoke the exemptions available for a controlled company as long as we remain a controlled company. As a result, shareholders will not have the same protection afforded to shareholders of companies that are subject to all of the NYSE American corporate governance requirements.

***Our controlling shareholder may take actions which are not necessarily in our interest or in the interest of our other shareholders.***

Our Class A Ordinary Shares, which are listed, have one vote per share, and our Class B Ordinary Shares have 10 votes per share. By virtue of their holdings of all of the issued and outstanding Class B Ordinary Shares, as of the date of this annual report, Ambipar holds approximately 96.0% of our voting power. Accordingly, except with respect to the limited matters as to which Cayman Islands corporate law requires approval by a majority of votes cast by shareholders other than the controlling shareholder, Ambipar controls and is expected to control all matters submitted to our shareholders for the foreseeable future, including the election of directors, certain amendments of our organizational documents, compensation matters, and any merger, consolidation, sale of all or substantially all of our assets, or other major corporate transaction requiring shareholder approval.

Ambipar may have interests that differ from ours or our other shareholders' and may vote in a way with which such shareholders disagree and which may be adverse to their interests. This concentrated control is likely to have the effect of limiting the likelihood of an unsolicited merger proposal, unsolicited tender offer, or proxy contest for the removal of directors. As a result, our governance structure and our governing documents may have the effect of depriving our shareholders of an opportunity to sell their shares at a premium over prevailing market prices and make it more difficult to replace our directors and management.

Additionally, being a controlled company, relevant risks materializing at the ultimate parent level could have a negative impact on the trading price of our Securities and our financial condition, credit ratings or reputation.

***As a foreign private issuer, we are exempt from a number of rules under the U.S. securities laws and are permitted to file less information with the SEC than a U.S. company. This may limit the information available to holders of our Securities.***

We are considered a "foreign private issuer" under the Exchange Act and are therefore exempt from certain rules under the Exchange Act, including the proxy rules, which impose certain disclosure and procedural requirements for proxy solicitations for U.S. and other issuers (including the requirement applicable to emerging growth companies to disclose the compensation of its Chief Executive Officer and the other two most highly compensated executive officers on an individual, rather than an aggregate, basis). Moreover, we have four months after the end of each fiscal year to file our annual report with the SEC, are not required to file certain periodic reports at all, and are not required to file other periodic reports and financial statements with the SEC as frequently or within the same time frames as U.S. issuers with securities registered under the Exchange Act. However, we issue, and expect to continue issuing, interim quarterly financial information publicly and furnish it to the SEC under cover of Form 6-K. We are not required to comply with Regulation FD, which imposes restrictions on the selective disclosure of material information to shareholders. In addition, our officers, directors and principal shareholders are exempt from the reporting and short-swing profit recovery provisions of Section 16 of the Exchange Act and the rules under the Exchange Act with respect to their purchases and sales of our Securities. Therefore, our shareholders may not know on a timely basis when our officers, directors and principal shareholders purchase or sell our Securities. Accordingly, investors may receive less or different information about us than you would receive about a U.S. issuer.

In addition, as a "foreign private issuer," we are permitted to follow certain home-country corporate governance practices in lieu of certain NYSE American requirements. A foreign private issuer must disclose in its annual reports filed with the SEC each NYSE American requirement with which it does not comply followed by a description of its applicable home country practice. We currently intend to follow some, but not all of the corporate governance requirements of the NYSE American. With respect to the corporate governance requirements that we do follow, we cannot make any assurances that we will continue to follow such corporate governance requirements in the future, and may therefore in the future, rely on available NYSE American exemptions that would allow us to follow our home country practice. Unlike the requirements of the NYSE American, we are not required to, under the corporate governance practice and requirements in the Cayman Islands, have our Board consisting of a majority of independent directors, nor are we required to have a compensation committee or a nomination or corporate governance committee consisting entirely of independent directors, or have regularly executive sessions with only independent directors each year. Such Cayman Islands home country practices may afford less protection to holders of our Securities.

***In the future, we may lose our foreign private issuer status, which would then require us to comply with the Exchange Act's domestic reporting regime and cause us to incur significant legal, accounting and other expenses.***

We could lose our status as a "foreign private issuer" under applicable securities laws and regulations if more than 50% of our outstanding voting securities become directly or indirectly held of record by residents of the United States and any one of the following is true: (i) the majority of our directors or executive officers are U.S. citizens or residents; (ii) more than 50% of our assets are located in the United States; or (iii) our business is administered principally in the United States, or if we fail to meet additional requirements necessary to avoid loss of foreign private issuer status. The determination of foreign private issuer status will be made annually on the last business day of our second fiscal quarter. Accordingly, we will next make a determination with respect to our foreign private issuer status on June 30, 2025.

If we lose our status as a "foreign private issuer" in the future, we will no longer be exempt from the rules described above and, among other things, will be required to file with the SEC periodic reports and annual and quarterly financial statements as if we were a company incorporated in the United States and modify certain of our policies to comply with corporate governance practices associated with U.S. domestic issuers. Such conversion and modifications would involve additional costs. In addition, we may lose our ability to rely upon exemptions from certain corporate governance requirements on U.S. stock exchanges that are available to foreign private issuers, which could also increase our costs. Further, our officers, directors and principal shareholders will become subject to the short-swing profit disclosure and recovery provisions of Section 16 of the Exchange Act. If this were to happen, we would likely incur substantial costs in fulfilling these additional regulatory requirements, including significant additional legal, accounting and other expenses, and members of our management would likely have to divert time and resources from other responsibilities to ensuring these additional regulatory requirements are fulfilled.

***We do not expect to pay dividends for the foreseeable future.***

We currently intend to retain our future earnings, if any, to finance the further development and expansion of our business and do not intend to pay dividends to shareholders in the foreseeable future. Any future determination to pay dividends will be at the discretion of our Board and will depend on our financial condition, results of operations, capital requirements, restrictions contained in the Cayman Islands Companies Act and in future agreements and financing instruments, business prospects and such other factors as our Board deems relevant. As a result, investors may not receive any return on an investment in our Class A Ordinary Shares unless they sell our Class A Ordinary Shares for a price greater than that which they paid for them. See "*Item 8.A. Financial Information—Consolidated Statements and Other Financial Information—Dividends and Dividend Policy*."

***Our only principal asset is our interest in Emergencia and, accordingly, we depend on distributions from Emergencia to pay our debts and other obligations.***

We are a holding company and have no material assets other than our interests in Emergencia. We are not expected to have independent means of generating revenue or cash flow, and our ability to pay taxes and operating expenses, as well as dividends in the future, if any, is dependent upon the financial results and cash flows of Emergencia. There can be no assurance that Emergencia will generate sufficient cash flow to distribute funds to us, or that applicable law and contractual restrictions, including negative covenants under any debt instruments, if applicable, will permit such distributions. In addition, according to the Deeds of Debentures and the IBBA Loan Agreement, Emergencia must maintain a minimum net debt to EBITDA ratio and, according to the Deeds of Debentures, Emergencia shall not pay dividends or interest on equity or make other distributions to its shareholders if an event of acceleration or an event of default has occurred and has not been cured within the applicable grace period set forth in the Deeds of Debentures. Emergencia may enter into additional financing or other agreements in the future that may restrict the distribution of dividends or other payments to shareholders. If Emergencia does not distribute sufficient funds to us to pay our taxes or other liabilities, we may default on contractual obligations or have to borrow additional funds. In the event that we are required to borrow additional funds, it could adversely affect our liquidity and subject us to additional restrictions imposed by lenders.

***Anti-takeover provisions in our governing documents might discourage, delay or prevent a change in control or changes in our management and, therefore, depress the trading price of our Securities.***

Our governing documents contain provisions that may make our acquisition more difficult, including the following:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• *Notice Requirements for Shareholder Proposals*. Cayman Islands law and our Articles provide that one or more shareholders together holding at least one-third of the votes entitled to be cast at our general meetings may request the convening of our extraordinary general meeting or the addition of one or more items to the agenda of any general meeting. The request must be deposited at the registered office and must be signed by the relevant requisitionists. Our governing documents also specify certain requirements regarding the form and content of a shareholder's requisition, including stating the purposes of the requested meeting. These requirements may make it difficult for our shareholders to bring matters before a general meeting.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• *Special Resolutions*. Our governing documents require special resolutions adopted at an extraordinary general meeting for any of the following matters, among other things: (a) a decrease of the share capital and of any capital redemption reserves, (b) an amendment to the governing documents or change of its name, (c) changing its registration to a different jurisdiction, (d) merge or consolidate with one or more constituent companies, upon such terms as the directors may determine, (e) change the number of directors of the Board and (f) in a winding up, direct the liquidator to divide amongst the shareholders our assets, value the assets for that purpose and determine how the division will be carried out between the shareholders or different classes of shareholders. Pursuant to our governing documents any special resolution may be adopted at a general meeting at which a quorum is present (except as otherwise provided by mandatory law) by the affirmative votes of at least two-thirds (2∕3) of the votes validly cast on such resolution by shareholders entitled to vote.

These anti-takeover provisions could discourage, delay or prevent a transaction involving a change in our control or changes in our management, even if such transaction would benefit our shareholders, and therefore, adversely affect the trading price of our Securities.

***The trading market for our Securities is influenced by the research and reports that analysts may publish about us, our business, our market and our competitors, or by the lack of any such research and reports. If we do not meet the expectations of these analysts, the market price of our Securities may decline.***

The trading market for our Securities depends in part on the research and reports that analysts publish about our business. We do not have any control over these analysts. If one or more of the analysts who cover us downgrade our Securities or publish inaccurate or unfavorable research about our business, the price of our Securities may decline. If few analysts cover us, demand for our Securities could decrease, and our Securities and trading volume may decline. Similar results may occur if one or more of these analysts stop covering us in the future or fail to publish reports on us regularly.

***We expect fluctuations in our results of operations, making it difficult to project future results, and if we fail to meet the expectations of analysts or investors with respect to our results of operations, our stock price could decline.***

Our results of operations have fluctuated in the past and are expected to fluctuate in the future due to a variety of factors, many of which are outside of our control. As a result, our past results may not be indicative of our future performance. In addition to the other risks described herein, factors that may affect our results of operations include the following:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• fluctuations in demand for or pricing of our service;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• our ability to attract new customers or retain existing customers;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• customer expansion rates;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• seasonality;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• investments in new features and functionality;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• the speed with which we are able to provide our services to customers;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• changes in customers' budgets, the timing of their budget cycles and purchasing decisions;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• our ability to control costs, including our operating expenses;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• the amount and timing of payment for operating expenses, particularly research and development and sales and marketing expenses;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• the amount and timing of non-cash expenses, including stock-based compensation, goodwill impairments and other non-cash charges;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• the amount and timing of costs associated with recruiting, training and integrating new employees and retaining and motivating existing employees;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• the effects and timing of acquisitions and their integration;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• general economic conditions, both domestically and internationally, as well as economic conditions specifically affecting industries in which our customers participate;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• fluctuations in currency exchange rates and changes in the proportion of our revenue and expenses denominated in foreign currencies;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• health epidemics or pandemics, such as the COVID-19 outbreak;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• the impact, or timing of our adoption, of new accounting pronouncements;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• changes in regulatory or legal environments that may cause us to incur, among other things, expenses associated with compliance;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• the overall tax rate for our business, which may be affected by the mix of income we earn in Brazil and in jurisdictions with different tax rates, the effects of stock-based compensation and the effects of changes in our business;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• the impact of changes in tax laws or judicial or regulatory interpretations of tax laws, which are recorded in the period such laws are enacted or interpretations are issued and may significantly affect the effective tax rate of that period;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• changes in the competitive dynamics of our market, including consolidation among competitors or customers; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• significant security breaches of, technical difficulties with, or interruptions to, the delivery and use of our services.

Any of these and other factors, or the cumulative effect of some of these factors, may cause our results of operations to vary significantly. If our quarterly results of operations fall below the expectations of investors or analysts who follow our stock, the price of our Securities could decline substantially, and we could face costly lawsuits, including securities class actions.

***Substantial future sales, or the perception of future sales, of our Securities could cause the market price of our Securities to decline, even if our business is doing well.***

Pursuant to the Investor Rights Agreement, Ambipar, the Sponsor and certain other persons listed thereto have agreed that, during the applicable lock-up period and subject to certain exceptions, they will not sell or assign, offer to sell, contract or agree to sell, hypothecate, pledge, grant any option to purchase or otherwise dispose of or agree to dispose of, directly or indirectly, or establish or increase a put equivalent position or liquidation with respect to or decrease a call equivalent position within the meaning of Section 16 of the Exchange Act with respect to, any of our Securities, enter into any swap or other arrangement that transfers to another, in whole or in part, any of the economic consequences of ownership of, or any other derivative transaction with respect to, any of our Securities, whether any such transaction is to be settled by delivery of such Security, in cash or otherwise, or publicly announce any intention to effect any such transaction. Further, the Investor Rights Agreement provides the Sponsor and certain other parties thereto with customary demand registration rights and piggy-back registration rights with respect to registration statements filed by us after the Closing. See "*Item 7.A. Major Shareholders and Related Party Transactions—Major Shareholders—Investor Rights Agreement*."

[T](#ib885b07745664dce8cc23d0d35721f6b_7)[able](#ib885b07745664dce8cc23d0d35721f6b_7)[of](#ib885b07745664dce8cc23d0d35721f6b_7)[Contents](#ib885b07745664dce8cc23d0d35721f6b_7)

Upon expiration of the applicable lock-up period and upon the effectiveness of any registration statement that we file pursuant to the above-referenced Investor Rights Agreement, in a registered offering of securities pursuant to the Securities Act or otherwise in accordance with Rule 144 under the Securities Act, our shareholders may sell large amounts of our Ordinary Shares in the open market or in privately negotiated transactions, which could have the effect of increasing the volatility in the trading price of our Class A Ordinary Shares or putting significant downward pressure on the trading price of our Class A Ordinary Shares.

Further, sales of our Ordinary Shares upon expiration of the applicable lockup period could encourage short sales by market participants. Generally, short selling means selling a security, contract or commodity not owned by the seller. The seller is committed to eventually purchase the financial instrument previously sold. Short sales are used to capitalize on an expected decline in the security's price. As such, short sales of our Ordinary Shares could have a tendency to depress the price of our Class A Ordinary Shares, which could increase the potential for short sales.

We cannot predict the size of future issuances of our Ordinary Shares or the effect, if any, that future issuances and sales of shares of our Ordinary Shares will have on the market price of our Class A Ordinary Shares. Sales of substantial amounts of our Ordinary Shares, or the perception that such sales could occur, may materially and adversely affect prevailing market prices of our Class A Ordinary Shares.

***An active trading market for our Securities may not be sustained, which would adversely affect the liquidity and price of our Securities.***

The price of our Securities may fluctuate significantly due to the market's reaction to our performance and general market and economic conditions. An active trading market for our Securities may never develop or, if it develops, it may not be sustained. Investors may be unable to sell their Ordinary Shares and Warrants unless a market can be established and sustained.

***We may be unable to satisfy listing requirements in the future, which could limit investors' ability to effect transactions in our Securities and subject us to additional trading restrictions.***

We may be unable to maintain the listing of our Securities in the future. If we are delisted, we could face significant material adverse consequences including:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• a limited availability of market quotations for our Securities;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• reduced liquidity for our Securities;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• a determination that our shares are a "penny stock" which will require brokers trading in our shares to adhere to more stringent rules, possibly resulting in a reduced level of trading activity in the secondary trading market for our Securities;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• a limited amount of news and analyst coverage; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• a decreased ability to obtain capital, pursue acquisitions, issue additional securities or obtain additional financing in the future.

***We may be required to take write-downs or write-offs, restructuring and impairment or other charges that could have a significant negative effect on our financial condition, results of operations and stock price, which could cause investors to lose some or all of their investment.***

We may be forced to write-down or write-off assets, restructure our operations, or incur impairment or other charges that could result in us reporting losses. Even though these charges may be non-cash items and not have an immediate impact on our liquidity, the fact that charges of this nature are reported, could contribute to negative market perceptions about us or our Securities. In addition, charges of this nature may cause us to violate net worth or other covenants to which we currently are and may in the future be subject. Accordingly, any of our shareholders could suffer a reduction in the value of their Securities as a result of the foregoing factors and would be unlikely to have a remedy for such reduction in value.

***We depend on our shareholder Ambipar for many support services, certain of which are provided only on a transitional basis while others may be provided for the foreseeable future on arms-length terms.***

We rely on certain administrative and other resources of Ambipar, including information technology, controllership, organization and corporate support activities, marketing, invoicing, debt collection, facilities, human resources, accounting documentation, archive, compliance, data privacy, fleet management, project assessment, quality assurance, labor safety, investor relations, sustainability advisory services, treasury and legal services, to operate its business. Emergencia entered into a Cost Sharing Agreement with Ambipar to retain the ability to use these resources. The Cost Sharing Agreement allows Ambipar to terminate the agreement, at its sole discretion, for as long as it controls us, with sixty days' prior written notice to Emergencia, and Emergencia to terminate the agreement with one hundred-eighty days' prior written notice to Ambipar, with the reimbursement of all reasonable and duly documented costs and expenses incurred by Ambipar until the date of the delivery of the written notice and all reasonable and duly documented additional costs and expenses that Ambipar reasonably incurs in order to cease and terminate the Cost Sharing Agreement. The services provided under the Cost Sharing Agreement may not be sufficient to meet our needs and may not be provided at the same level as when the entities comprising Emergencia were direct and indirect wholly-owned subsidiaries of Ambipar. Emergencia and Ambipar will rely on each other to perform their obligations under the Cost Sharing Agreement. If Ambipar is unable to satisfy its material obligations under the agreement, or if the agreement is terminated, we may not be able to obtain such services at all or obtain the services on terms as favorable as those in the Cost Sharing Agreement, and could as a result suffer operational difficulties or significant losses. See also "—*Risks Relating to Our Business and Industry—We may face potential conflicts of interest in negotiations with related parties*."

In addition, before entering into the Cost Sharing Agreement, Emergencia and its subsidiaries received informal support from Ambipar as wholly owned subsidiaries of Ambipar, and the level of this informal support may diminish as we become a more independent company. Any failure or significant interruption of our own administrative systems or in the Ambipar's administrative systems during the term of the Cost Sharing Agreement could result in unexpected costs, impact our results or prevent us from paying our suppliers or employees and performing other administrative services on a timely basis.

***Our business and operations could be negatively affected if we become subject to any securities litigation, shareholder activism, regulatory actions or compliance issues which could cause us to incur significant expenses, hinder execution of business and growth strategies, including by distracting our management and impacting the price of our Securities.***

In the past, following periods of volatility in the market price of a company's securities, securities class action litigation has often been brought against that company. Shareholder activism, which could take many forms or arise in a variety of situations has been increasing recently, especially in the context of special purpose acquisition company business combinations. Volatility in the share price of our Securities or other reasons may in the future cause us to become the target of securities litigation or shareholder activism. Securities litigation and shareholder activism, including potential proxy contests, could result in substantial costs and divert our management attention and resources from our business. Additionally, such securities litigation and shareholder activism could give rise to perceived uncertainties as to our future, adversely affect our relationships with customers and make it more difficult to attract and retain qualified personnel. Also, we may be required to incur significant legal fees and other expenses related to any securities litigation and activist shareholder matters. Further, the price of our Securities could be subject to significant fluctuation or otherwise be adversely affected by the events, risks and uncertainties of any securities litigation and shareholder activism.

***The dual class structure of our Ordinary Shares may adversely affect the trading market for our Class A Ordinary Shares.***

We cannot predict whether our dual class structure will result in a lower or more volatile market price of our Class A Ordinary Shares or in adverse publicity or other adverse consequences. For example, certain index providers have announced restrictions on including companies with dual class or multi-class share structures in certain of their indices. In July 2017, S&P Dow Jones and FTSE Russell announced changes to their eligibility criteria for the inclusion of shares of public companies on certain indices, including the Russell 2000, the S&P 500, the S&P Mid Cap 400 and the S&P SmallCap 600, to exclude companies with multiple classes of shares from being added to these indices. Beginning in 2017, MSCI Inc. ("MSCI"), a leading stock index provider, opened public consultations on their treatment of no-vote and multi-class structures and temporarily barred new multi-class listings from certain of its indices; however, in October 2018, MSCI announced its decision to include equity securities "with unequal voting structures" in its indices and to launch a new index that specifically includes voting rights in its eligibility criteria. As a result, our dual class capital structure would make us ineligible for inclusion in indices that exclude companies with multi-class share structures, and mutual funds, exchange-traded funds and other investment vehicles that attempt to passively track these indices will not be investing in our Class A Ordinary Shares. We cannot assure you that other stock indices will not take a similar approach to S&P Dow Jones or FTSE Russell in the future. Exclusion from indices could make our Class A Ordinary Shares less attractive to investors and, as a result, the market price of our Class A Ordinary Shares could be adversely affected.

***We may redeem unexpired Warrants prior to their exercise at a time that is disadvantageous to warrantholders, thereby making their Warrants worthless.***

We have the ability to redeem our outstanding Warrants, at any time prior to their expiration, at a price of $0.01 per warrant if, among other things, the last reported sale price of our Class A Ordinary Shares for any 20 trading days within a 30-trading day period ending on the third trading day prior to the date on which they send the notice of redemption to the warrantholders ("Reference Value") equals or exceeds $18.00 per share (as adjusted). If and when the Warrants become redeemable, we may exercise our redemption right even if we are unable to register or qualify the underlying securities for sale under all applicable state securities laws. As a result, we may redeem our Warrants as set forth above even if the holders are otherwise unable to exercise our Warrants. Redemption of our outstanding Warrants as described above could force holders to: (1) exercise their Warrants and pay the exercise price therefor at a time when it may be disadvantageous for them to do so; (2) sell their Warrants at then-current market price when they might otherwise wish to hold their Warrants; or (3) accept the nominal redemption price which, at the time the outstanding Warrants are called for redemption, we expect would be substantially less than the market value of their Warrants.

In addition, we have the ability to redeem our outstanding Warrants at any time prior to their expiration, at a price of $0.10 per Warrant if, among other things, the Reference Value equals or exceeds $10.00 per share (as adjusted). In such a case, the holders will be able to exercise their Warrants prior to redemption for a number of our Class A Ordinary Shares determined based on the redemption date and the fair market value of our Class A Ordinary Shares. The value received upon exercise of our Warrants (1) may be less than the value the holders would have received if they had exercised their Warrants at a later time where the underlying share price is higher and (2) may not compensate the holders for the value of the Warrants, including because the number of ordinary shares received is capped at 0.361 Class A Ordinary Shares per Warrant (subject to adjustment) irrespective of the remaining life of the Warrants.

In the event that we elect to redeem all of our outstanding Warrants, we would only be required to have the notice of redemption mailed by first class mail, postage prepaid by us not less than 30 days prior to the redemption date to registered holders of the outstanding Warrants to be redeemed at their last address as they shall appear on the registration books.

***Our management has the ability to require holders of our Warrants to exercise such Warrants on a cashless basis which would cause holders to receive fewer ordinary shares upon their exercise of the Warrants than they would have received had they been able to exercise their Warrants for cash.***

If we call our Warrants for redemption after the redemption criteria described elsewhere in this annual report have been satisfied, our management will have the option to require any holder that wishes to exercise their Warrant (including any Warrants held by the Sponsor, HPX's former officers or directors or their permitted transferees) to do so on a "cashless basis." If our management chooses to require holders to exercise their Warrants on a cashless basis, the number of Class A Ordinary Shares received by a holder upon exercise will be fewer than it would have been had such holder exercised his Warrant for cash. This will have the effect of reducing the potential "upside" of the holder's investment in us.

**Risks Relating to U.S. Tax**

***We may be or may become a passive foreign investment company ("PFIC"), which could result in adverse U.S. federal income tax consequences to U.S. Holders of our Class A Ordinary Shares.***

If we are (or our predecessor HPX is) a PFIC for any taxable year (or portion thereof) that is included in the holding period of a U.S. Holder (as defined in "Item 10.E. Additional Information—Taxation—Certain United States Federal Income Tax Considerations") of our Class A Ordinary Shares, such U.S. Holder may be subject to adverse U.S. federal income tax consequences and additional reporting requirements. Based on the past and projected composition of our income and assets and the value of our assets, including goodwill, we do not believe we were a PFIC for our most recent taxable year, and we do not expect to become a PFIC in the current taxable year or the foreseeable future, although there can be no assurance in this regard.

However, the determination of whether we are a PFIC is an annual factual determination that can be made only after the end of each taxable year. Accordingly, it is possible that we may become a PFIC in the current or any future taxable year due to changes in our asset or income composition.

Additionally, even if we are not a PFIC, our Class A Ordinary Shares may be treated as stock of a PFIC with respect to a U.S. Holder that held HPX Class A Ordinary Shares in a prior taxable year in which HPX was treated as a PFIC. Absent certain elections, a determination that we are a PFIC (or, in the circumstances described above, that HPX was a PFIC) for any taxable year in which a U.S. Holder holds shares in such entity will generally continue to apply to such U.S. Holder for subsequent years in which such U.S. Holder continues to hold shares in such entity (including a successor entity), whether or not such entity continues to be a PFIC.

For a more detailed discussion of the PFIC rules and the risks and tax consequences of PFIC classification to U.S. Holders of our Class A Ordinary Shares, please see "*Item 10.E. Taxation — Certain United States Federal Income Tax Considerations — Passive Foreign Investment Company*." U.S. Holders should consult their tax advisors regarding the application of the PFIC rules to holders of our Class A Ordinary Shares.

**Item 4. INFORMATION ON THE COMPANY**

**A.History and Development of the Company**

Ambipar Emergency Response's history dates back to April 2008, when we founded our environmental emergencies operations as part of the broader Ambipar Group created in 1995 by Mr. Tercio Borlenghi Junior, who is the chairman of our Board and our indirect controlling shareholder.

Over the years following our foundation, we focused on building a fully integrated platform in Latin America by executing a strategy to increase our reach, market share and complementary portfolio of services through strategic acquisitions, thus being established as a leading environmental, emergency response and industrial field services provider in Brazil. To expand our operations, we acquired SOS COTEC — Consultoria e Tecnologia e Ecológica S.A. ("SOS COTEC") in September 2011, then one of the main Brazilian providers of emergency response services on highways.

In July 2012, the Ambipar Group acquired 51% of the share capital of Emergencia, which controlled the companies Suatrans Emergência S.A. ("Suatrans Brazil") and Suatrans Chile S.A. ("Suatrans Chile"), one of the main emergency response service providers in relation to railroads and industrial plants in Brazil. Through this acquisition, we entered the Chilean market, launching our international operations.

In 2016, we acquired Ecosorb S.A. in Brazil and began our operations in the emergency response segment at ports and port terminals.

In January 2018, the Ambipar Group acquired the remaining outstanding share capital of Emergencia, which became our parent company.

Due to the demand for emergency solutions from our customers in Europe, we acquired Braemar Response Ltd.

In 2019, we acquired Atmo Hazmat Ltda., which focuses on road emergencies in Brazil. During that same year, as part of Ambipar Group's rebranding strategy, we renamed all the companies in our group under the AMBIPAR brand, strengthening our brand and image so that customers would have a unified perception of all of our group activities.

In 2020, Ambipar went public and, as a result, we implemented several initiatives to strengthen the quality of our corporate governance, including the adoption of an audit committee at the Ambipar level, and a robust risk management policy.

**B.Business Overview**

**Our Purpose and Vision**

Our purpose is to help our customers address environmental and sustainability challenges to contribute to a sustainable world and protect the environment for the generations to come.

Our vision is to become a global reference in client-focused, integrated environmental solutions.

**Overview**

We are a leading environmental, emergency response and industrial field service provider in Brazil with presence in 41 countries in Latin America, North America, Europe, Africa, Antarctica, Asia and Oceania as of December 31, 2024. Through our international platform, our sophisticated special equipment and our highly qualified personnel, we provide our customers with a full suite of environmental services organized around prevention, training and emergency response on all transportation modes. Our portfolio includes a broad variety of services such as environmental remediation, industrial field services, industrial cleaning of chemical and non-chemical products and of hazardous and non-hazardous waste, consulting services focused on accident prevention and environmental licensing. We believe we are pioneers in offering several environmental and industrial field services across the value chain, in addition to being a market leader for innovation and the use of cutting-edge environmental technologies.

Our diversified customer base of over 11,000 customers as of December 31, 2024 ranges from local to blue chip and multinational companies operating in a wide range of industries, including chemicals, pulp and paper, mining, oil and gas, logistics, power, steel, meatpacking and cement, among others. Our broad and recurrent portfolio includes services contracted through our subscription model, such as emergency response services for highway accidents, industrial chemical spills and dry port emergencies, as well as services contracted through spot agreements, such as gas decommissioning, industrial silo cleaning and underground gas tanking cleaning.

We started our environmental emergencies operations in 2008 as part of the broader Ambipar Group founded in 1995 by Mr. Tercio Borlenghi Junior, chairman of our Board and our indirect controlling shareholder. Over the years, we have focused on building a fully integrated platform in Latin America by applying a strategy of increasing our reach, market share and complementary services through strategic acquisitions, including the acquisitions of SOS COTEC in 2011, Suatrans Brazil and a stake in Suatrans Chile in 2012, and WGRA in 2018. In 2021, we acquired Ambipar Response ES S.A. (formerly known as Controlpar Participações S.A.), thereby improving our portfolio of accident prevention services. In 2022, we have completed six acquisitions in Brazil that expanded the breadth of our services offering, including Dracares Apoio Marítimo e Portuário Ltda, which strengthened our oil spill operations; Flyone Serviço Aéreo Especializado, Comércio e Serviços Ltda., through which we began our activities of fighting wildfires through aircrafts; and CTA Serviços em Meio Ambiente Ltda., through which we act in the rescue of animals and recovery of flora impacted by oil spills.

In 2018, we started our international expansion with the acquisition of Braemar Response Ltd., a British company founded in 1948 with extensive experience in responding to environmental emergencies, responding to our customers' demand in Europe. In 2020, we acquired Allied International Emergency, LLC in the United States, which provides emergency response, environmental remediation and industrial services. In addition to that acquisition, since 2020, we have completed seven other acquisitions in the United States, including the WOB Acquisition, six in Canada (including our recent acquisition of Ridgeline Canada Inc. in August 2022), two in Europe and two in Latin America (including the consolidation of our control of Suatrans Chile). We believe that the WOB Acquisition has been and continues to be transformational for us as it strengthened our presence on continents where we were already active and allowed us entry into Asia and Oceania.

In 2022, we executed more than 37,000 service deliveries to our customers. We organize our services within three categories: (i) emergency response and industrial field services; (ii) consulting services focused on accident prevention and environmental licensing; and (iii) training services.

In 2023 and 2024, the Company managed its business with a focus on organic growth as the main guideline, increase cash generation, deleveraging, and focus on efficiency and integration of processes and acquired companies.

***Emergency Response and Industrial Field Services***

Our emergency response and industrial field service category comprises the response to accidents involving hazardous and non-hazardous chemical and non-chemical products and waste and natural disasters (fire, flood, and hurricanes), as well as tank cleaning, silo cleaning, asbestos removal, vessel and container cleaning, waste transportation and disposal, soil remediation, turnaround, and decommissioning. We also provide biological emergency management and response services, including in relation to epidemics and pandemics such as the COVID-19 pandemic. Over the years, we have been called to remediate significant environmental accidents, such as the 2019 Brumadinho mining dam collapse in Brazil, and the 2015 fire in Port of Santos in Brazil, which lasted 10 days, as well as the Callao oil spill at the Peruvian shoreline, characterized by the Peruvian Ministry of Foreign Affairs as one of the worst climate disasters in recent times. In addition, we supported containment efforts relating to the COVID-19 pandemic in the United Kingdom, in conjunction with the British army, and in Brazil at office buildings, schools, and in aircraft, buses, and other locations. Considering our prominent role in emergency situations, we have been recognized as a point of reference by public authorities in Brazil, such as the Brazilian Marines, which sent a number of its Marines to train at our training grounds in Nova Odessa, São Paulo, Brazil.

In order to serve our customers efficiently and expeditiously, we operate through a broad network of service centers (some of which are dedicated to specific customers), which are strategically distributed across South America, North America, Europe, Africa and Antarctica. These service centers are equipped with high-quality assets that are subject to frequent preventive maintenance to keep them in excellent condition and we follow standard procedures for each hazardous material category in accordance with the safety guidelines set forth by the United Nations. As of December 31, 2024, we had 469 service centers across five continents.

Our service centers are linked to four regional fully automated centralized operations centers — one in Brazil operating nationwide and in Antarctica, one in Chile serving countries in Latin America other than Brazil, one in the United Kingdom serving Europe and Africa, and one in the United States serving North America. These operation centers manage the emergency response services and other jobs by centralizing the strategic decisions involved in the process of serving our customers. They are responsible for operating a 24/7/365 dedicated hotline that responds to our customers' orders for emergency response and industrial field services, both subscribed and at spot, and, when required, promptly send the appropriate commands to the service center that is closest to the location where the service will be rendered. These operations centers can track assets in real time by using geographic information system — GIS and geoprocessing tools, and therefore allow for a fast and efficient deployment of equipment and personnel to handle the relevant service.

***Consulting services focused on accident prevention and environmental licensing***

Our consulting services include highly complex accident prevention and environmental impact studies for various industries to mitigate accident risks and ensure client compliance with the requirements under the applicable environmental licensing processes. Over the past 15 years, we have performed several consulting projects to clients in sectors such as oil and gas, mining, energy, infrastructure and logistics, ports and terminals, sanitation, steel, petrochemicals, beverages and pulp and paper. Our consulting business operates via a Global Environmental Solutions (GES) platform, offering complete and innovative environmental products and services to our customers, with a portfolio including studies of locational alternatives for projects, environmental licensing, construction management and HSE (Health, Safety and Environment) as well as the execution of environmental programs, management of contaminated areas, effluents and contaminant waste. We seek to innovate in connection with the technical delivery of our products and services, through the development of technological solutions that optimize results using digital tools and geotechnologies, which initiatives culminated in the formation of a partnership with the Environmental Systems Research Institute — ESRI<sup>®</sup>.

***Training Services***

In addition, we offer more than 40 professional training programs related to preventing, fighting and remediating emergencies. These services are supported by our proprietary multimodal training centers, in which we perform real-world simulations and provide periodic training to customers, as well as our employees and government agents that cooperate with us in the field, such as environmental agencies, firefighters, policemen, the army and the navy, in each case from countries such as the United Kingdom, Portugal, Brazil, Chile and Argentina, among others. As of December 31, 2024, we had four training centers in North and South America.

We participate in technical cooperation programs with several high-profile environmental agencies, which include the publishing of technical articles on emergency protocols to governmental authorities as well as the attendance of meetings and audiences with various governmental authorities and non-governmental associations, including the Brazilian Association of Technical Standards (*Associação Brasileira de Normas Técnicas — ABNT*) in Brazil and the National Fire Protection Association — NFPA in the United States, to contribute our expertise to the development of supporting materials and of technical standards. For example, in line with changes in legislation on the storage and transportation of hazardous products, we publish a Hazardous Products Self-Protection Manual, which is currently in its 16<sup>th</sup> edition. In 2019, we launched the first edition of the Manual for the Environmental Emergency Prevention and Readiness in Ports, Marinas and Terminals.

As of December 31, 2024, we employed approximately 7,400 people, including trained responders, who are trained to follow applicable regulatory guidelines and rigorous safety protocols.

**Our Competitive Strengths**

We are a leading environmental, emergency response and industrial field service provider in Brazil with a strong and growing global presence. We plan to build on our core strengths to continue serving a wide range of important customers across the world.

***Competitive advantages in a substantially fragmented market.***

The global market for environmental, emergency response and industrial field services is substantially fragmented. In addition, on a global level, there are only few competitors with the capabilities to offer their services globally and as a result, we believe that our value proposition to offer a diversified portfolio of environmental, emergency response and industrial field services covering an extensive geographical area across the supply chain has a strong appeal for customers, in particular clients that operate globally such as multinational petrochemical and commodities companies. Moreover, we believe that our exclusive focus on environmental, emergency response and industrial field services in multiple countries sets us apart from our competitors. Typically in a fragmented market such as ours, most players are local, covering small geographies and covering particular services niches. We are one of very few companies with an international reach as well as specialized personnel on-the-ground to service local markets, enabling us to act both at the local, national and international levels.

Entering and expanding internationally in a market such as ours requires significant financial resources, operating expertise and a qualified workforce to build profitable operations. We believe that our leading position in Brazil together with our long history in the marketplace, international scale and proficiency, safety profile, comprehensive service capabilities, capillarity, and highly-skilled and trained personnel serve as solid competitive advantages, which we believe help us foster and maintain customer loyalty and mitigate the risks of competitive pressure.

***Standardized services rendered at large scale.***

We rendered high-quality environmental, emergency response and industrial field services on over 14,300 billed hours in 2024 through our network of service centers spread across five continents and furnished with state-of-the-art equipment, which are linked to our four regional, fully automated centralized operations centers that expedite our response to customer demand. We carefully select the locations of our service centers to optimize our network. The density of our network helps us stay close to our clients and increase our client base. In addition, our multimodal training centers ensure that our staff receives what we believe to be industry-leading training in order to best serve our customers following the utmost quality and safety standards.

In addition, by hiring and training our technical staff in Brazil to serve customers across the world, we believe that we can take advantage of our scale and know-how to deliver superior services at a lower cost than players who operate only in developed countries, thus improving our margins. For instance, with the acquisition of Controlpar Participações S.A. in 2021, we increased our staff of highly-qualified technical employees located in Brazil, who create customized solutions to support our customers' needs for sustainability, environment, oceanography, geoprocessing, outsourced technical personnel, and managing system at a global scale.

***Increased commitment to sustainable practices under a favorable regulatory environment.***

We are committed to integrating sustainability into our business practices. One of our main goals is to help our clients adopt and improve their environmental, social and governance ("ESG") practices and mitigate adverse environmental impacts of their operations on communities. We believe that our services are conducive to long-term sustainability, and that the global transition towards sustainable practices presents an attractive business opportunity within our industry. In 2020, we joined the United Nations Global Compact, the largest corporate sustainability initiative in the world organized by the United Nations, and committed to joining efforts to advance all 17 of the United Nations' sustainable development goals — SDGs, including developing inclusive and sustainable industrialization, supporting affordable and clean energy, fighting climate change, restoring and protecting life below water and on land, ending extreme poverty, improving gender equality and reducing other inequalities, among other goals. By joining the Global Compact, we took an important step towards the full alignment of our business with social and environmental sustainability standards and reinforced our commitment to these values, which we also seek to transmit to our customers.

Sustainability is not only a priority for us, but increasingly also for our clients. Businesses across the globe continue to realize that a focus on sustainability is ever more important to meeting the increasing demands and expectations of customers and stakeholders for environmental responsibility. In addition to market demand, sustainable practices are prompted by a new and stricter regulatory framework together with increasing regulatory oversight, incentivizing or mandating green practices. In Brazil and elsewhere, applicable rules and regulations assign criminal liability to environmental damages. As a result, we believe that it is increasingly essential for businesses to have a global, trustworthy and recognized environmental, emergency response and industrial field services provider like us to help them navigate the complex compliance rules as well as adopt appropriate procedures to respond to sustainability challenges.

***Solid financial performance and consistent growth.***

We have demonstrated our ability to grow our business through a combination of organic growth, accretive acquisitions and tight cost control, while remaining resilient through slow economic cycles such as during the COVID-19 pandemic.

Our track-record of profitable growth is largely a result of a disciplined strategy of pursuing accretive acquisitions and our ability to integrate companies of different sizes. Since our founding in 2008, we have completed 36 acquisitions. Our experience in identifying suitable targets, acquiring them on what we believe are relatively attractive terms and integrating them successfully into our business has generated significant profit and cash flow accretion. Our business model enables us to leverage our position to optimize the purchase price paid for these acquisitions while using our acquired network to generate synergies and benefits of scale. We seek to capture operational and financial synergies, ensuring quality, operational efficiency and sustainable growth. We also benefit from the expertise brought by the targets in their niche services. For example, with our acquisitions in the United States, we have added asbestos cleaning to our portfolio of services, and by acquiring Lehane Environmental and Industrial Services Limited in Ireland, we integrated their technology and expertise in tank cleaning. We then incorporate the target's expertise to expand our offering in all of our markets. By bringing new expertise into our offerings, we improve our portfolio and increase customer retention.

Further, the success of our international expansion demonstrates our strong ability to enter into new markets through acquisitions. The specialization and ability to provide services at scale allows us to be competitive internationally. For further information about our recent acquisitions, see "—*A. History and Development of the Company*."

In addition, we have built a business which we believe will achieve a strong organic growth, which is based on four pillars consisting of (i) operating through standardized service centers, (ii) building and operating centralized emergency operation centers, (iii) offering hazardous materials training centers and (iv) participating in relevant technical committees across the jurisdictions where we operate. The combination of these pillars allows us to be a one-stop-shop for emergency and industrial services, which has translated into a historical organic growth in its client base, an increase in services provided and consequently an increase in net revenue and profits over the years.

***Large and diversified customer base with long-standing relationships.***

We serve more than 11,000 clients in 41 countries (including Antarctica), many of which have decade- long relationships with us and several of which have been using our services on a recurring basis for more than five years. Our customer base consists of a broad mix of clients, spanning from local transport companies to multinational mining companies. Our clients operate in a variety of industries, such as chemicals, pulp and paper, mining, oil and gas, logistics, power, steel, meatpacking, cement, among others. The breadth of our offering allows us to become deeply embedded within our clients, who rely on us to undertake an essential role for their core business, and creates cross-selling opportunities. Our capabilities and customized solutions allow us to build strong client relationships that grow and expand over time. We believe that our long-standing customer relationship and diverse customer base limits our credit exposure to any one customer and potential cyclicality in any one industry.

In addition, the listing of our parent Ambipar in the Brazilian stock exchange enhanced and expanded our relationship with blue-chip companies, which rely on high compliance and governance standards required from listed companies. Becoming a publicly listed company in the United States with shares traded in the NYSE American will open doors to many new opportunities that we can capitalize on.

***Highly experienced management team and well-established corporate governance practices.***

We operate in a well-structured manner to facilitate the effective execution of our growth plan. The principal managers of our technical teams have more than 20 years of experience in our industry and more than 7 years of experience, on average, working with us. Our experienced team has already demonstrated its ability to grow our business.

Our management team is supported by Ambipar's internal compliance and audit committees and organized under strict corporate governance policies and guidelines, which are in the center of all our actions. We strive for excellence in corporate governance, which is fundamental to how we manage and operate our company, from our everyday business to ESG issues. Ambipar is also listed on the Novo Mercado segment of the B3, which has the strictest governance requirements on the B3.

**Our Strategy**

We believe we can continue to scale our business and expand our footprint well into the future. We aim to continue strengthening our market position by implementing the key strategies set forth below.

***Continue investing in our international expansion through acquisitions, in particular in North America.***

We intend to further strengthen and expand our international footprint and to selectively enter new markets. We already operate a sizeable international business and intend to replicate the successful business model of our Latin American operations to other countries in the developed markets with the goal of becoming a global leader in our industry. For the execution of our acquisition strategy in various geographies, we apply a methodology that uses specific qualitative and quantitative criteria to identify and carefully select targets, which results in the identification of companies, the acquisition of which we believe has a high probability of creating value, as shown in the chart below.

In particular, we seek to grow in the North American market, which benefits from a strong demand and a developed regulatory framework. In the United States, we will continue to prioritize geographic and portfolio expansion through organic investments. Our U.S. acquisition strategy contemplates as key elements finding local targets with solid reputation in local markets, passionate and experienced management teams, entrepreneurs and business owners who share our vision for long-term growth (and who we usually keep on as employees for at least the transition process), sustainable value creation and strong corporate culture. We believe that this strategy facilitates a smooth integration process and that such acquired companies comply with the highest standards of quality that in turn facilitate growth within our platform. The WOB Acquisition, our largest acquisition to date, is aligned with this strategy and we believe will not only significantly strengthen our position in the United States, including as a result of Witt O'Brien's presence in the public sector, but also allow us access to the Asian and Oceanian markets, which will significantly expand our global reach.

By expanding our operations internationally, we aim at reducing costs through centralizing back-office operations of our acquired assets and optimizing performance through cross-selling services across different geographies, which has a direct impact in the acquired companies' margins and, as a result, increases our return on investment.

***Strengthen market share in Brazil and in other markets by capitalizing on market growth opportunities, with strong tailwind from ESG compliance.***

We expect that the remediation and industrial field services market will grow faster than global GDP growth in the short to medium-term. We understand that the remediation and industrial field services market growth is driven by nominal GDP growth and increased demand for compliance with stricter ESG regulations. A stronger GDP is associated with more transportation of hazardous materials, an increase in industrial activity and, thus, increased events which demand service expertise. In addition, our industry has seen a global outsourcing trend, which is driven by the need for specialization and lower costs to clients. We intend to leverage our position as a leading environmental, emergency response and industrial field services provider in Brazil with a broad geographic footprint to benefit from the expected market growth and gain market share in the several markets we serve. We believe that a business strategy that bundles extensive geographic coverage with a broad portfolio of standardized services constitutes a strong value proposition for customers. We are continuously looking for new possibilities to expand and innovate our business model, our footprint and product offering. We intend to capitalize on our difficult-to-replicate combination of standardized services to provide a one-stop-shop for emergency response and industrial field services. We believe our focus on sustainability, workforce safety and innovation, as well as our passionate commitment to customer service, provides for a long-term sustainable business model. In addition to organic growth initiatives, the fragmentation in our market offers significant opportunities for consolidation through M&A activity, and we will continue to pursue acquisition opportunities to expand our geographic reach, service lines and customer base.

***Invest in our commercial team to increase cross-selling and in business development with potential customers.***

As we expand our geographical footprint and services portfolio of acquired companies, we seek to benefit from our scale and the breadth of our services to increase cross-selling and ultimately drive incremental volume into our services. Cross-selling is largely driven by our capability of sharing know-how and technology developed among our businesses in different markets to our clients globally. In Brazil, for example, we did not customarily offer industrial services. We are now offering the services of industrial cleaning, specialized in cleaning of contaminant products and confined environments to our Brazilian clients, an expertise we gained from the North American companies that we acquired. In addition, the WOB Acquisition has provided us with a new and complementary customer base and has created and we believe will further create meaningful commercial synergy opportunities that we expect will be materialized through cross-selling initiatives between consulting services, such as post-emergency mitigation planning and applications development, and our current offering of large-scale emergency response services.

As part of this strategy, we intend to further develop relationships with multinational, blue chip clients that require extensive geographic coverage. Our commercial team is an essential part of our organic business development strategy. From 2019 to 2024, we opened 270 service centers only in Brazil. We plan to invest in new commercial offices as well as in training our commercial team and those of acquired companies to strengthen our relationship with existing customers and attract new customers. In addition, we seek to leverage our acquired companies' client portfolio by generating business leads through the recommendation of complementary services to those already provided to these clients by the acquired companies.

**Our Services and Operations**

We serve customers from various industries, including logistics (highways, railways, airports, ports and port terminals), chemical, oil and gas, mining, energy, infrastructure, agribusiness and construction.

We offer a one-stop-shop platform of emergency, prevention and routine services rendered at scale and organized within three business units, namely (i) Subscription, (ii) Field Services, Maintenance & Routine Emergency; and (iii) High Impact Emergency.

| High impact emergency | 5.6% | 4.6% | n.a. |

---

*Subscription*

Our entire portfolio of services can be contracted through a subscription model (with contracts having a one to three-year term) with fixed-rates and recurring stand-by contracts, containing an agreed price, defined duration and specified materials. Monthly subscription paid to have access to stand-by services and other predefined time and materials resources such as stand-by contracts for shipping companies, where our teams remain available for interventions; and contracts with the shipping industry that offer documentary support and assistance to vessels.

*Field Services, Maintenance & Routine Emergency*

Through our Field Services, Maintenance & Routine Emergency business unit we perform services on a recurring basis and generally approved by the customer, based on master service agreements, or MSAs, such as maintenance of industries during scheduled shutdowns, tank, silo and vessel cleaning and maintenance, as well as blasting, excavation, inspection of critical facilities, soil remediation and decontamination, and routine emergencies that require cleaning and clearance.

We also provide a comprehensive portfolio of consulting services including highly complex accident prevention and environmental impact studies for various industries to mitigate accident risks and ensure client compliance with the requirements under the applicable environmental licensing processes. Over the past 16 years, we have performed several consulting projects for clients in sectors such as oil and gas, mining, energy, infrastructure and logistics, ports and terminals, sanitation, steel, petrochemicals, beverages and pulp and paper. Our consulting business operates via a Global Environmental Solutions (GES) platform, offering complete and innovative environmental products and services to our customers, with a portfolio including studies of locational alternatives for projects, environmental licensing, construction management and HSE (Health, Safety and Environment) as well as the execution of environmental programs, management of contaminated areas, effluents and contaminant residue. We seek to innovate the technical delivery of our products and services, through the development of technological solutions that optimize results using digital tools and geotechnologies. These initiatives culminated in the formation of a partnership with the Environmental Systems Research Institute—ESRI®. In addition, we offer more than 40 professional training programs to our customers related to preventing, fighting and remediating emergencies. These services are supported by our proprietary multimodal training centers, in which we perform real-world simulations and provide periodic training to customers, as well as our employees and government agents that cooperate with us in the field, such as environmental agencies, firefighters, policemen, armies and navies, in each case from countries such as the United Kingdom, Portugal, Brazil, Chile and Argentina, among others.

We participate in technical cooperation programs with several high-profile environmental agencies. In connection with these programs, we publish technical articles on emergency protocols to governmental authorities as well as participate in meetings and surveys with various governmental authorities and non-governmental associations, including the Brazilian Association of Technical Standards (Associação Brasileira de Normas Técnicas—ABNT) in Brazil and the National Fire Protection Association—NFPA in the United States—to contribute our expertise to the development of supporting materials and of technical standards. For example, in line with changes in legislation regulating the storage and transportation of hazardous products, we publish a Hazardous Products Self-Protection Manual, which is currently in its 16th edition. In 2019, we launched the first edition of the Manual for the Environmental Emergency Prevention and Readiness in Ports, Marinas and Terminals.

*High Impact Emergency*

Through our High Impact Emergency business unit, we respond to accidents involving hazardous and non-hazardous chemical and non-chemical products and residue and natural disasters with contract values exceeding US$1 million per occurrence, such as fighting wildfires, offshore oil spills, floods, hurricanes, and large-scale industrial fires. We also provide biological emergency management and response services, including in relation to epidemics and pandemics such as the COVID-19 pandemic. Over the years, we have been called to remediate significant environmental accidents, such as the 2019 Brumadinho mining dam collapse in Brazil, and the 2015 fire in Port of Santos in Brazil, which lasted 10 days, as well as the Callao oil spill at the Peruvian shoreline, characterized by the Peruvian Ministry of Foreign Affairs as one of the worst climate disasters in recent times. In addition, we supported containment efforts relating to the COVID-19 pandemic in the United Kingdom, in conjunction with the British army, and in Brazil at office buildings, schools, and in aircraft, buses and other locations. Considering our prominent role in emergency situations, we have been recognized as a point of reference by public authorities in Brazil, such as the Brazilian Marines, which sent several of its Marines to train at our training grounds in Nova Odessa, Brazil. As of December 31, 2024, Brazil represented 37% of total revenue from high impact emergencies, while Europe and North America represented 36% and 27%, respectively.

In order to serve our customers efficiently and expeditiously, we operate through a broad network of service centers (some of which are dedicated to specific customers), which are strategically distributed across South America, North America, Europe, Africa and Antarctica. These service centers are equipped with high-quality assets that are subject to frequent preventive maintenance to keep them in optimal condition, and we follow standard procedures for each hazardous material category in accordance with the safety guidelines set forth by the United Nations. As of December 31, 2024, we had 469 service centers across six continents.

Our service centers are linked to four regional fully automated centralized operations centers — one in Brazil operating nationwide and in Antarctica, one in Chile serving countries in Latin America other than Brazil, one in the United Kingdom serving Europe and Africa, and one in the United States serving North America. These operation centers manage emergency response services and other jobs by centralizing the strategic decisions involved in our client service processes. They are responsible for operating a 24/7/365 dedicated hotline that responds to our customers' orders for emergency response and prevention and routine services, and, when required, promptly send the appropriate commands to the service center that is closest to the location where the service will be rendered. These operations centers can track assets in real time by using geographic information system — GIS and geoprocessing tools—and therefore allow for a fast and efficient deployment of equipment and personnel to handle the relevant service.

The chart below shows the workflow of our Control Tower emergency response and industrial field services operations (other than in the United States, which is still in the process of rollout):

![Image_0.jpg](ambi-20241231_g1.jpg)

Since 2006, we have been committed to maintaining the highest level of hazmat procedures and standards for emergency responses, which we view as the golden standard for emergency responses. We comply with the 470 requirements set forth by the National Fire Protection Association — NFPA's Standard for Competence of Responders to Hazardous Materials/ Weapons of Mass Destruction Incidents, and we are the only foreign company that is part of the NFPA's technical committee, which is comprised of governmental authorities and legal entities involved in the chemical industry.

Given our know-how in emergency response services, Latin American clients often rely on us to develop dedicated emergency response centers including centers such as a 24-hour emergency response management center, and centers for civil and industrial firefighters, and industrial plants, railway and mining emergency specialists.

**Suppliers**

We maintain a long-term relationship with our suppliers, which we periodically evaluate based on financial and technical criteria. We have implemented supplier management processes, including methodology for approving the contracting of suppliers based not only on the quality of the product and its price, but also on the reputation of the suppliers, their financial condition, delivery guarantees and product availability. There is no relevant concentration of suppliers, measured as a percentage of costs or related revenues attributable to products and/or services provided by suppliers.

**Competition**

Competition within our industry varies by locality and by type of service rendered, and competitors include several major national and regional environmental services firms, as well as numerous smaller local firms, including outsourcing companies, though no one competitor directly competes with our full suite of offerings. Clean Harbors, Inc. and US Ecology, Inc. are or have been U.S. publicly-listed companies that render competing services within their portfolio.

The principal competitive factors applicable to our services are quality of performance, price, breadth of service portfolio, operational efficiency and reliability of services, availability of specialized equipment and latest technologies, skilled, technical, and professional personnel, customer-service oriented culture, regulatory compliance and safety record, industry reputation and brand name recognition.

We believe that we are competitive in all markets we serve and that we offer a unique mix of services, including niche technologies and services that favorably distinguish us from competitors. We also believe that our strong brand name recognition, compliance and safety record, customer service reputation and positive relations with regulators, government agents and local communities enhance our competitive position.

**Our People**

As of December 31, 2024, we employed approximately 7,400 full-time employees. A substantial portion of these employees are represented by labor unions, through approximately 100 collective bargaining agreements. See "*Item 6.D. Directors, Senior Management and Employees—Employees*" for additional information.

**Sales Channels and Marketing Efforts**

We seek to expand market awareness of the breadth of our service offerings to current and future customers through targeted marketing opportunities, including:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Direct sales pipeline development and management;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Maintain an online presence through our website and social media channels by utilizing video, written content and social implementations to create awareness;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Speaking engagements at industry conferences;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Networking within our established channels;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Direct sales channel management programs including both inbound and outbound programs and client referrals; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Public relations campaigns.

Our direct sales channel is core to our go-to-market strategy. We believe that regional, vertical, and broader domain expertise, as well as continued client management, are critical to our sales success. Our regional sales teams respond to our chief operating officer and are located in the United States, Canada, Latin America and Europe. Our regional sales teams augments direct sales capabilities by cultivating existing relationships and identifying cross-sell and up-sell opportunities of additional solutions.

We focus our sales and marketing efforts on generating leads to develop our sales pipeline, building brand and vertical awareness, scaling our network of partners, and growing our business from our existing client base and that of acquired companies. Our sales leads primarily come through inbound digital channels including our website, content marketing efforts, lead generation and account-based marketing tactics, phone calls, virtual events, and industry trade shows and associations.

We typically follow a "land-and-expand" strategy as our clients engage with us on more than one solution as we grow our partnership. For example, multinational clients who initially engage with us locally tend to rely on our scalability to adopt a full-suite enterprise solution. Once our clients experience the depth of our ability to handle their multi-faceted environmental needs, our regional sales teams are able to successfully cross-sell and up-sell other solutions, creating a large avenue of revenue generation with minimal incremental acquisition cost.

**Research and Development**

Our competitiveness depends on, among other things, our ability to anticipate trends and to identify and respond to new and changing consumer preferences. We therefore devote significant resources to various research and development activities to design, create and develop new solutions. See "*Item 5.C. Operating and Financial Review and Prospects—Research and Development, Patents and Licenses, etc*." for additional information.

**Seasonality**

Our business in general is not subject to seasonality, however, during the second half of the year there is usually a higher incidence of weather and climate change events in the Northern Hemisphere.

**Environmental Social and Governance, or ESG**

Environmental, organizational and financial sustainability initiatives have been key components of our success since we were founded in 2008. We continuously monitor and evaluate new technologies and investments that can enhance our commitment to the environment, to the safety of our employees and to the communities we serve. These investments align with our focus on value creation for all stakeholders and we remain committed to expanding these efforts as our industry and technology continue to evolve.

In 2020, we adhered to the United Nations Global Compact, the largest corporate sustainability initiative in the world organized by the United Nations, and committed to join efforts to advance all 17 sustainable development goals — SDGs, including developing inclusive and sustainable industrialization, supporting affordable and clean energy, fighting climate change, restoring and protecting life below water and on land, ending extreme poverty, improving gender equality and reducing other inequalities, among other goals. By joining the Global Compact, we took an important step towards the full alignment of our business with social and environmental sustainability standards and reinforced our commitment to these values, which we carry over to our customers.

We recognize the importance of disclosure surrounding these initiatives and strive to become increasingly transparent through the continued use and adoption of new ESG frameworks, expansion of ESG-related data points, as well as participation at ESG-related industry events and other investor engagements.

*Quality, Safety and Management*

Safety is a core value in our company. A large number of our employees work as drivers, heavy equipment operators and sorters and are exposed to the inherent risks of on-field work. We rely on incident and accident indicators such as total recordable incident rate — TRIR, fatality rate, disabling injury rate, frequency rate and severity rate, which are constantly monitored, and apply methodologies for action plans. To guide safety management, we use an integrated management system, which is used to perform operation analyses related to health, safety at work, environment and quality, establishing guidelines for achieving the outlined objectives.

All operations are conducted based on risk management and undergo environmental risk assessment, including mechanical, physical, chemical, ergonomic, and biological assessment to minimize risks in our operations and for our customers. For the analysis of these qualitative or quantitative risks, we adopt national and international regulatory standards.

We strive to fully comply with environmental legislation and health and safety standards, in accordance with the quality standards applicable to our business.

Employees learn safety best practices through new-hire and ongoing technical, legal, security and operational training. Our trainings are directed at teams according to their specific needs. All employees undergo regulatory training and refresher trainings from time to time.

As part of our efforts to apply the highest quality, safety and management standards, we have obtained the following certificates: ISO 9001 (quality management system), ISO 14001 (environmental management system), ISO 45001 (occupational health and safety management system) and ISO 22320 (emergency management).

**Intellectual Property**

Ambipar owns relevant brands, domain names, trademarks and copyrights linked to our activities in Brazil, Colombia, the United States and the United Kingdom, which we are entitled to use. Technology, sophisticated deep learning methodologies, human capital, unpatented trade secrets, pending trademarks and domain names are key to our success.

As of the date of this annual report, we use Ambipar's trademark portfolio as part of the Ambipar Group, including 14 registrations. Ambipar has also applied and is in the process of obtaining a total of 5 trademarks in Argentina, Canada, and the United States, which are relevant to our business.

------

[T](#ib885b07745664dce8cc23d0d35721f6b_7)[able](#ib885b07745664dce8cc23d0d35721f6b_7)[of](#ib885b07745664dce8cc23d0d35721f6b_7)[Contents](#ib885b07745664dce8cc23d0d35721f6b_7)

The principal owned trademark that we license from Ambipar's portfolio brands to use in our business is "Ambipar Response" and "Ambipar," which Ambipar has registered or is in the process of registering in all of the countries in which we operate. We entered into the Trademark Licensing Agreement with Ambipar under which Ambipar formally granted us with a non-exclusive, non-assignable, non-sublicensable and non-transferable license to use the trademarks "Ambipar Response," "Grupo Ambipar" and "Ambipar" in any country or territory where we and our affiliates operate and do business, for an indefinite period of time. See "*Item 7.B. Major Shareholders and Related Party Transactions—Related Party Transactions—Trademark Licensing Agreement*."

We also enter into software license agreements with third parties, develop internal software and enter into service agreements for the use of software to perform our services. Under our employment contracts, except when otherwise provided, all industrial designs and software developed by employees as part of their employment relationship with us remain our exclusive property. As of the date of this annual report, we held title to five registered and several unregistered proprietary software in Brazil.

As of the date of this annual report, we own the domain names ambiparresponse.cl, ambiparresponse.co, ambiparresponse.com.py, ambiparresponse.pe, ambiparresponse.uk and ambiparresponse.ca, but we use the domain name *https:// ir.response.ambipar.com*, which is registered with the Registro.br (the Brazilian internet domain name registry) under the name of Ambipar as well as other domain names registered by Ambipar with other internet domain name registries in foreign jurisdictions.

We devote significant resources to the protection and enhancement of our intellectual property assets and actively monitor the market for infringements or abuses of our trademarks and product designs. We are also active in enforcing our rights against third-party infringements. In addition, we monitor third-party applications for registration of trademarks that could be confused with our trademarks, and file oppositions against the applications for, or the registration of such trademarks in accordance with the laws and regulations of the relevant jurisdictions and cooperate with competent authorities worldwide to fight the counterfeiting of our products.

**Legal and Administrative Proceedings**

From time to time, we may become involved in legal proceedings or be subject to claims arising in the ordinary course of business, including labor and civil proceedings. Regardless of the outcome, litigation can have an adverse impact on us because of defense and settlement costs, diversion of management time and resources, reputation and other factors.

We are not presently a party to any legal proceedings that, if determined adversely to us, would individually or taken together have a material adverse effect on our business, operating results, financial condition or cash flows. As of December 31, 2024, we recorded a provision for contingencies in the amount of R$0.4 million. For additional information, see note 15.1 to our audited Consolidated Financial Statements included elsewhere in this annual report.

**Regulatory Overview**

Our business has benefited substantially from increased government regulation. In addition, the environmental services industry itself is the subject of extensive and evolving regulation by federal, state, provincial and local authorities in all countries in which we operate. We are constantly monitoring the regulatory environment in the different jurisdictions in which we operate, which regulatory environment is often influenced by changes in leadership at the federal, state, provincial and local levels. We make a continuing effort to anticipate regulatory, political and legal developments that might affect our operations and/or strategic initiatives but cannot guarantee that we are always able to do so successfully. In addition, we cannot predict the extent to which any legislation or regulation that may be enacted or enforced in the future may affect our operations.

Below is a summary of the most relevant regulations applicable to our activities in our principal markets in terms of revenue and size of operations.

*Brazilian regulation applicable to our activities*

<u>Transportation of waste and hazardous products in Brazil</u>

The transportation of hazardous waste is regulated by the Brazilian Road Transport National Agency (ANTT) Resolution No. 5947/2021, which requires, in addition to technical requirements for the transport of these materials, the registration of transporters of hazardous products on highways and certain classifications for each type of waste, schedules of risk precedence, limited quantity transport, and identification of packaging, among others.

We are also subject to NBR 7500 issued by the Brazilian Association of Technical Norms — ABNT, which sets forth specific technical requirements related to risk labels and safety panels during loading, transportation, unloading, transshipment, cleaning and decontamination of hazardous products, as well as to NBR norms 9735 and 14619 issued by the ABNT, which set forth technical requirements and proceedings for the identification of land transportation and safety equipment.

<u>Environmental laws and regulations</u>

Environmental laws and regulations set forth strict liability regimes, and their breach can give rise to administrative, criminal and civil liabilities. In administrative matters, penalties such as fines of up to R$50 million may be applied, which may also be doubled or tripled in the event of a repeated offense, in addition to an embargo and suspension of activities. The violation of environmental norms can also subject violators to criminal liability, with jail time or restrictive rights as penalties.

In civil matters, the law sets forth joint and several liability among the agents that are responsible, directly or indirectly, for the activity that caused environmental damage. The obligation to repair damages to the environment is not subject to a statute of limitations.

*U.S. regulation applicable to our activities*

Our properties and operations in the United States are subject to regulation under a broad range of federal, State and local laws and regulations relating to the protection of the environment, natural resources and worker and public health and safety. In addition to environmental, health and safety obligations imposed under statutory laws or governmental regulations, our United States properties and operations are also impacted by obligations and liabilities imposed under common law, including regarding potential common law liability for personal injuries related to exposure to hazardous materials.

United States environmental, health and safety laws are subject to change and have, in general, become more stringent over the passage of time. The most significant United States federal environmental laws affecting us are the Comprehensive Environmental Response, Compensation and Liability Act (the "Superfund Act") and the Resource Conversation and Recovery Act ("RCRA"). The laws of the individual States in which we operate often have State law analogues to the Superfund Act and RCRA, which in some circumstances are more stringent than the similar federal laws.

The Superfund Act is the primary federal statute regulating the cleanup of inactive hazardous substance sites and imposing liability for damages caused in connection with such cleanup on the responsible parties. The statute provides for strict and, in certain cases, joint and several liability of the parties involved in the generation, transportation and disposal of hazardous substances for the cost of these responses and for the cost of damages to natural resources. Under the Superfund Act, by reason of our business activities, including the management and performance of contaminated site remediations, we may be deemed liable as a generator or transporter of a hazardous substance which is released into the environment, as a person who arranged for the disposal of a hazardous substance, or as the owner or operator of a facility at or from which there has been a release of a hazardous substance into the environment.

RCRA is the principal federal statute governing hazardous waste generation, treatment, transportation, storage and disposal. Pursuant to RCRA, the United States Environmental Protection Agency has established a comprehensive "cradle-to-grave" system for the management of a wide range of materials identified as hazardous waste. Hazardous wastes generated in connection with our business operations may be subject to stringent regulation under RCRA and State law analogues. Additionally, certain wastes which may be generated in connection with our operations, but which may not be subject to regulation under the federal Superfund Act or RCRA, such as certain nonhazardous wastes or petroleum or petroleum-impacted material, can nevertheless be stringently regulated under other State and local environmental laws.

To the extent that our operations impact water bodies, including wetlands, or the atmosphere, we are subject to regulation under, respectively, the federal Clean Water Act ("CWA") and the federal Clean Air Act ("CAA"). The laws of the individual States in which we operate often have State law analogues to the CWA and CAA, which in some circumstances are more stringent than the similar federal laws. The CWA prohibits the discharge of pollutants into the waters of the United States without government authorization and regulates the discharge of pollutants into surface waters and sewers from a variety of sources, including remediation sites, disposal sites and treatment facilities. The CAA regulates the emission of pollutants into the air, including, in some instances, air emissions generated during remedial activities. To the extent that our operations involve the remediation or management of polychlorinated biphenyls — PCBs or materials contaminated by PCBs, we are also subject to regulation under the federal Toxic Substances Control Act.

*Privacy and Data Protection*

The laws on privacy and data protection have evolved in recent years in order to establish more objective rules on how personal data may be used by organizations.

In Brazil, the rights to privacy are generally guaranteed by the Brazilian Federal Constitution, the Brazilian Civil Code and the Brazilian Consumer Protection Code, but, in the absence of more specific rules on the subject, the legitimacy of practices involving the use of personal data was historically ruled upon on a case-by-case basis by legal courts. Until August 2018, when the Brazilian Data Protection Law No. 13,709/2018, as amended by Law No. 13,853/2019 (*Lei Geral de Proteção de Dados Pessoais*, or the "LGPD") was approved, the practices related to the use of personal data were regulated by sparse and sectorial laws only.

The LGPD came into force on September 18, 2020 to regulate the processing of personal data and the right to privacy and data protection in Brazil. The LGPD applies to individuals or legal entities, either private or governmental entities, that process or collect personal data in Brazil and which processing activities aim at offering or supplying goods or services to data subjects located in Brazil, regardless of the individuals' or legal entities' country of domicile or where the data is located. The LGPD establishes detailed rules for the collection, use, processing and storage of personal data and affects all economic sectors, including the relationship between clients and suppliers of goods and services, employees and employers and other relationships in which personal data is collected, whether in a digital or physical environment.

Since the entry into force of the LGPD, all processing agents/legal entities are required to adapt their data processing activities to comply with this new set of rules. We have implemented changes to our policies and procedures designed to ensure our compliance with the relevant requirements under the LGPD and we are carrying out an ongoing improvement of our privacy governance. Even so, as it is a recent law, the Brazilian National Data Protection Authority (Autoridade Nacional de Proteção de Dados, or the "ANPD") as regulatory agency may raise other relevant issues or provide new guidance that will require further action from us to remain fully compliant.

The ANPD has powers and responsibilities similar to the European data protection authorities, exercising a triple role, including: (i) a regulatory role, with the power to issue standards and procedures, decide on the interpretation of the LGPD and request information from controllers and operators; (ii) a punishing role, in case of breach of law, through an administrative process; and (iii) an education role, with the responsibility to disseminate information and promote knowledge of the LGPD and security measures, promoting standards of services and products that facilitate data control and preparing studies on national and international practices for the protection of personal data and privacy, among others. The ANPD has ensured technical independence, although it is subordinated to the President of Brazil.

The penalties for violations of the LGPD include: (i) warnings imposing a deadline for the adoption of corrective measures; mandatory disclosure of investigated and confirmed violations; (ii) restriction, temporary block and/or deletion of personal data; (iii) a fine of up to 2% of the company's or group's revenue, subject to the limit of R$50 million per violation; (iv) daily fines, subject to the aforementioned global limit; (v) partial or total prohibition of activities related to data processing, either temporarily or permanently; and (vi) publication of the violation. Under the LGPD, security breaches that may result in significant risk or damage to data subjects must be reported to the ANPD within a reasonable time period (no more than 2 business days). Moreover, the ANPD could establish other obligations related to data protection that are not described above. In addition to administrative sanctions, as a result of any noncompliance with the obligations established by the LGPD, we can be held liable for individual or collective material damages, and moral damages caused to data subjects, including when caused by third parties that serve as data processors on our behalf.

The imposition of the administrative sanctions by the ANPD does not prevent the imposition of administrative sanctions set forth by other laws that address issues related to data privacy and protection in Brazil, such as Law No. 8,078/1990, or the Brazilian Code of Consumer Defense, and Law No. 12,965/ 2014, or the Brazilian Internet Act, as applicable. Public prosecutors and consumer protection authorities (such as the National Consumer Secretariat — Senacon, and State or municipal consumer protection bodies, known as Procons) and class associations may file collective lawsuits for breach of privacy laws.

In the United States, California enacted the California Consumer Privacy Act ("CCPA"), which took effect in January 2020 and limits how we may collect, use and process personal data of California residents. The CCPA establishes a privacy framework for covered companies such as ours by, among other things, creating an expanded definition of personal information, establishing data privacy rights for California residents, including, among other things, the right to request a copy from a covered company of the personal information collected about them, the right to request deletion of such personal information, and the right to opt out of certain sales of personal information, and creating a potentially severe statutory damages framework and private rights of action for certain data breaches. Further, in November 2020, California voters approved the California Privacy Rights Act (the "CPRA"). The CPRA, which became effective on January 1, 2023, imposes additional obligations on companies covered by the legislation and significantly modifies the CCPA, including by expanding California residents' rights with respect to their personal data, and by establishing a regulatory agency dedicated to implementing and enforcing the CCPA (as amended by the CPRA). The effects of the CCPA and CPRA are potentially far-reaching, and may require us to modify our data processing practices and policies and incur substantial compliance-related costs and expenses. Further, although there has been some enforcement activity and guidance, it remains unclear how various provisions will be interpreted and enforced. In addition, the CCPA and CPRA could mark the beginning of a trend toward more stringent privacy legislation in the United States, which could increase our potential liability and adversely affect our business. Virginia, Colorado, Utah and Connecticut have all passed comprehensive privacy statutes that are currently effective and 12 additional states have passed laws that will become effective by 2026. Furthermore, all 50 states have laws including obligations to provide notification of certain security breaches to affected individuals, state officials and others.

In the EU, the EU General Data Protection Regulation ("GDPR"), went into effect in May 2018, and has and will continue to result in significantly greater compliance burdens and costs for companies with users and operations in the EU and EEA by imposing stringent administrative requirements for controllers and processors of personal data of EU residents, including, for example, data breach notification requirements, requirements on the cross-border transfer of data, limitations on retention of information, and rights for individuals over their personal data. The GDPR also provides that EU member states may introduce their own further laws and regulations limiting the processing of personal data. Ensuring compliance with the GDPR is an ongoing commitment that involves substantial costs, and despite our efforts, data protection authorities or others (including individual consumers) may asset that our business practices fail to comply with its requirements. Violations of GDPR requirements may result in fines and other penalties, including bans on processing and transferring personal data and change of business practices. In particular, serious breaches of the GDPR can result in administrative fines of up to 4.0% of annual worldwide revenues or up to €20 million, whichever is higher. Such penalties are in addition to any civil litigation claims by data controllers, clients and data subjects.

Since January 1, 2021, we are also required to comply with the UK equivalent of the GDPR, the implementation of which exposes us to two parallel data protection regimes in Europe, each of which potentially authorizes similar fines and other enforcement actions for certain violations.

In addition, recent legal developments in Europe have created compliance uncertainty regarding transfers of personal data from Europe to the United States. In July 2020, the Court of Justice of the European Union, or CJEU, invalidated the EU-U.S. Privacy Shield Framework, a mechanism for the transfer of personal information from the EU to the United States, and made clear that reliance on Standard Contractual Clauses, an alternative mechanism for the transfer of personal information outside of the EU alone may not be sufficient in all circumstances. Authorities in Switzerland have also issued guidance calling the Swiss-U.S. Privacy Shield Framework inadequate and raising similar questions about the Standard Contractual Clauses. At present, there are few, if any, viable alternatives to the Standard Contractual Clauses (e. g., the Binding Corporate Rules (BCRs)). However, in March 2022, the United States and the European Commission announced that they had reached an agreement in principle to replace the Privacy Shield Framework with a new data transfer framework, the EU-U.S. Data Privacy Framework (DPF). In July 2023, the European Commission adopted an adequacy decision approving the DPF which permits a business to transfer personal data from the E.U. to the United States following a certification to the Department of Commerce that the business will adhere to data privacy principles. If we are unable to implement sufficient safeguards to ensure that our transfers of personal information from the EU are lawful, we may face increased exposure to regulatory actions, substantial fines and injunctions against processing personal information from the EU. Loss of our ability to lawfully transfer personal data out of the EU to these or any other jurisdictions may cause reluctance or refusal by current or prospective European customers to use our products or services, and we may be required to increase our data processing capabilities in the EU at significant expense. Additionally, other countries outside of the EU have passed or are considering passing laws requiring local data residency, which could increase the cost and complexity of delivering our services.

Further, the UK's withdrawal from the EU and ongoing developments in the United Kingdom have created uncertainty regarding data protection regulation in the United Kingdom. As of January 1, 2021, we are required to comply with the GDPR as well as the UK equivalent, the implementation of which exposes us to two parallel data protection regimes in Europe, each of which potentially authorizes similar fines and other enforcement actions for certain violations. However, going forward, there may be increasing scope for divergence in application, interpretation and enforcement of the data protection law as between the United Kingdom and the EEA, and the relationship between the United Kingdom and the EEA in relation to certain aspects of data protection law remains uncertain. In addition, while the UK data protection regime currently permits data transfers from the UK to the EU and other third countries covered by a European Commission adequacy decision, this will automatically expire in June 2025 unless the European Commission re-assesses and renews/extends that decision. Any such changes could have implications for our transfer of personal data from the UK to the EU and other countries.

In 2024, Ambipar Response S/A and Ambipar Response Ireland Limited drafted a Data Processing Agreement (DPA) for the international transfer and processing of employee data from the Ireland division to the Brazil division. This DPA meets the requirements of the GDPR, in accordance with the guidelines of the Data Protection Commission (DPC) of Ireland. The agreement covers the transfer of data necessary for payroll processing, human resources management, and the consolidation of financial information related to labor costs.

In addition to the DPA, an International Data Transfer Agreement (IDTA) was also drafted between Ambipar Response S/A, in Brazil, and Ambipar Response UK Limited, in the United Kingdom. This agreement formalizes the terms and conditions governing the international transfer of employee personal data between the two divisions, from the United Kingdom to Brazil. It establishes safeguards for the international transfer of data itself, ensuring that it complies with the GDPR. The agreement defines the legitimate purposes for the processing of this data by the importer, including, but not limited to: payroll processing, human resources management, and the consolidation of financial information related to labor costs.

For the year 2025, Ambipar plans to execute these agreements and establish a more seamless data transfer process between its European divisions and Brazil. Ambipar also expects to create a global data privacy office, which will be managed by Ambipar ESG. Given the company's international operations, which span a wide range of countries and jurisdictions, each with distinct data protection regulations, this office will play a fundamental role in harmonizing privacy and data protection practices across all of the group's operations, including the Company. It will be responsible for establishing guidelines and policies aligned with applicable legislation, such as LGPD, GDPR, CCPA, and other international data privacy regulations.

***Artificial Intelligence***

In April 2021, the European Commission introduced the first EU law on artificial intelligence, implementing a risk-based classification system. AI systems are assessed and categorized based on the level of risk they pose to users, with higher risks requiring stricter compliance measures. In June 2024, the EU approved the world's first AI regulations (the "EU AI Act"). The EU AI Act will take full effect 24 months after its entry into force, but some provisions will apply earlier:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• The ban on AI systems posing unacceptable risks took effect on February 2, 2025.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Codes of practice will be enforced nine months after the law enters into force.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Rules for general-purpose AI systems requiring transparency compliance will apply 12 months after the law's entry into force.

High-risk AI systems will have an extended timeframe to meet compliance requirements, as the obligations for them will take effect 36 months after the law's entry into force.

For more information see "*Item 3. D. Risk Related To the European Union Artificial Intelligence Act and Brazil's Artificial Intelligence Legal Framework Bill, especially regarding exposure to high-risk AI systems as defined in the regulations and the lack of adequate protection for individuals affected by the use of artificial intelligence*".

**Compliance**

We regard compliance with applicable regulations as a critical component of our overall operations. We strive to maintain the highest professional standards in our compliance activities. We have a dedicated team responsible for the facilities' permitting and regulatory compliance, compliance training, transportation compliance and related record keeping. To ensure the effectiveness of our regulatory compliance program, our dedicated team also monitors our facilities' operations are monitored.

Our facilities are frequently inspected and audited by regulatory agencies, as well as by customers. We believe that each of our facilities is currently in substantial compliance with applicable permit requirements.

**Item 5. OPERATING AND FINANCIAL REVIEW AND PROSPECTS**

**A.Operating Results**

The following discussion of our financial condition and results of operations should be read in conjunction with our audited Consolidated Financial Statements for each of the three years ended December 31, 2024, and the notes thereto, included elsewhere in this annual report, as well as the information presented under "*Financial Statement Presentation*" and "*Item 3.D—Key Information—Risk Factors*."

**Overview**

We are a leading environmental, emergency response and industrial field service provider in Brazil with presence in 41 countries in Latin America, North America, Europe, Africa, Antarctica, Asia and Oceania as of December 31, 2024. Through our international platform, our sophisticated special equipment and our highly qualified personnel, we provide our customers with a full suite of environmental services organized around prevention, training and emergency response on all transportation modes. Our portfolio includes a broad variety of services such as environmental remediation, industrial field services, industrial cleaning of chemical and non-chemical products and of hazardous and non-hazardous waste, consulting services focused on accident prevention and environmental licensing. We believe we are pioneers in offering several environmental and industrial field services across the value chain, in addition to being a market leader for innovation and the use of cutting-edge environmental technologies.

Our diversified customer base of over 11,000 customers as of December 31, 2024 ranges from local to blue chip and multinational companies operating in a wide range of industries, including chemicals, pulp and paper, mining, oil and gas, logistics, power, steel, meatpacking and cement, among others. Our broad and recurrent portfolio includes services contracted through our subscription model, such as emergency response services for highway accidents, industrial chemical spills and dry port emergencies, as well as services contracted through spot agreements, such as gas decommissioning, industrial silo cleaning and underground gas tanking cleaning.

We started our environmental emergencies operations in 2008 as part of the broader Ambipar Group founded in 1995 by Mr. Tercio Borlenghi Junior, chairman of our Board and our indirect controlling shareholder. Over the years, we have focused on building a fully integrated platform in Latin America by applying a strategy of increasing our reach, market share and complementary services through strategic acquisitions, including the acquisitions of SOS COTEC in 2011, Suatrans Brazil and a stake in Suatrans Chile in 2012, and WGRA in 2018.

In 2018, we started our international expansion with the acquisition of Braemar Response Ltd., a British company founded in 1948 with extensive experience in responding to environmental emergencies, responding to our customers' demand in Europe. In 2020, we acquired Allied International Emergency, LLC in the United States, which provides emergency response, environmental remediation and industrial services. In addition to that acquisition, since 2020, we have completed seven other acquisitions in the United States, including the WOB Acquisition, six in Canada (including our recent acquisition of Ridgeline Canada Inc. in August 2022), two in Europe and two in Latin America (including the consolidation of our control of Suatrans Chile). We believe that the WOB Acquisition has been and continues to be transformational for us as it strengthened our presence on continents where we were already active and allowed us entry into Asia and Oceania. In 2023 and 2022, we executed more than 52,000 and 37,000 service deliveries to our customers, respectively. We organize our services within three categories: (i) emergency response and industrial field services; (ii) consulting services focused on accident prevention and environmental licensing; and (iii) training services.

In 2021, we acquired Ambipar Response ES S.A. (formerly known as Controlpar Participações S.A.), thereby improving our portfolio of accident prevention services. In 2022, we have completed six acquisitions in Brazil that expanded the breadth of our services offering, including Dracares Apoio Marítimo e Portuário Ltda, which strengthened our oil spill operations; Flyone Serviço Aéreo Especializado, Comércio e Serviços Ltda., through which we began our activities of fighting wildfires through aircrafts; and CTA Serviços em Meio Ambiente Ltda., through which we act in the rescue of animals and recovery of flora impacted by oil spills.

In 2023, we completed 10 acquisitions which were Girassol Apoio Marítimo Ltda (Brasil), Ekman – Serviços Ambientais e Oceanográficos Ltda (Brasil), Plimsoll Serviços Ltda (Brasil), DFA Contracting Ltd (Canadá), RMC2 Soluções Ambientais Ltda (Brasil), Unidroid Robotica Do Brasil Ltda (Brasil), Smr Socorro Médico E Resgate Ltda (Brasil), Ssmr Saude Ocupacional Ltda. Epp (Brasil), Ssr Servicos De Seguranca E Resgate Ltda Epp (Brasil), Ambipar Response Maritime Services PDA S.A.(Brasil). Also in 2023, Ambipar Holding Canada (Holding Canada) established a holding company "Ambipar Response Industrial Services Canada (Industrial Services Canada)" and transferred all operating companies of "Industrial Services" (Orion, Lynx, Emerge and Graham) to this new Group holding company. Holding Canada acquired 100% of the company 1653395 Alberta Ltda (controlling company of Bulldog) and part of the payment to shareholders was in shares of the company Industrial Services Canada. At this time, Holding Canada transfers the shares of 1653395 Alberta Ltda to Industrial Services Canada. After this corporate movement, Holding Canada holds 70% control of Industrial Services Canada and 30% remains with Burly's Holdings Ltd.

**Business Combination**

On March 3, 2023, we consummated the previously announced Business Combination pursuant to the Business Combination Agreement, by and among HPX, the Company, Ambipar Merger Sub, Emergencia and Ambipar. As a result of the Business Combination, Emergencia has become our wholly owned direct subsidiary. On March 6, 2023, our Class A Ordinary Shares and Warrants commenced trading on the NYSE American under the symbols "AMBI" and "AMBI.WS," respectively.

For additional information on the expected main impacts of the Business Combination on our results of operations, balance sheet and cash flow statement, see "—*B. Liquidity and Capital Resources*."

We also provide a comprehensive portfolio of consulting services including highly complex accident prevention and environmental impact studies for various industries to mitigate accident risks and ensure client compliance with the requirements under the applicable environmental licensing processes. Over the past 16 years, we have performed several consulting projects for clients in sectors such as oil and gas, mining, energy, infrastructure and logistics, ports and terminals, sanitation, steel, petrochemicals, beverages and pulp and paper. Our consulting business operates via a Global Environmental Solutions (GES) platform, offering complete and innovative environmental products and services to our customers, with a portfolio including studies of locational alternatives for projects, environmental licensing, construction management and HSE (Health, Safety and Environment) as well as the execution of environmental programs, management of contaminated areas, effluents and contaminant residue. We seek to innovate the technical delivery of our products and services, through the development of technological solutions that optimize results using digital tools and geotechnologies. These initiatives culminated in the formation of a partnership with the Environmental Systems Research Institute—ESRI®. In addition, we offer more than 40 professional training programs to our customers related to preventing, fighting and remediating emergencies. These services are supported by our proprietary multimodal training centers, in which we perform real-world simulations and provide periodic training to customers, as well as our employees and government agents that cooperate with us in the field, such as environmental agencies, firefighters, policemen, armies and navies, in each case from countries such as the United Kingdom, Portugal, Brazil, Chile and Argentina, among others.

We participate in technical cooperation programs with several high-profile environmental agencies. In connection with these programs, we publish technical articles on emergency protocols to governmental authorities as well as participate in meetings and surveys with various governmental authorities and non-governmental associations, including the Brazilian Association of Technical Standards (Associação Brasileira de Normas Técnicas—ABNT) in Brazil and the National Fire Protection Association—NFPA in the United States—to contribute our expertise to the development of supporting materials and of technical standards. For example, in line with changes in legislation regulating the storage and transportation of hazardous products, we publish a Hazardous Products Self-Protection Manual, which is currently in its 16th edition. In 2019, we launched the first edition of the Manual for the Environmental Emergency Prevention and Readiness in Ports, Marinas and Terminals.

*High Impact Emergency*

Through our High Impact Emergency business unit, we respond to accidents involving hazardous and non-hazardous chemical and non-chemical products and residue and natural disasters with bills exceeding US$1 million per occurrence, such as fighting wildfires, offshore oil spills, floods, hurricanes, and large-scale industrial fires. We also provide biological emergency management and response services, including in relation to epidemics and pandemics such as the COVID-19 pandemic. Over the years, we have been called to remediate significant environmental accidents, such as the 2019 Brumadinho mining dam collapse in Brazil, and the 2015 fire in Port of Santos in Brazil, which lasted 10 days, as well as the Callao oil spill at the Peruvian shoreline, characterized by the Peruvian Ministry of Foreign Affairs as one of the worst climate disasters in recent times. In addition, we supported containment efforts relating to the COVID-19 pandemic in the United Kingdom, in conjunction with the British army, and in Brazil at office buildings, schools, and in aircraft, buses and other locations. Considering our prominent role in emergency situations, we have been recognized as a point of reference by public authorities in Brazil, such as the Brazilian Marines, which sent several of its Marines to train at our training grounds in Nova Odessa, Brazil. As of December 31, 2024, Brazil represented 37% of total revenue from high impact emergencies, while Europe and North America represented 36% and 27%, respectively.

In order to serve our customers efficiently and expeditiously, we operate through a broad network of service centers (some of which are dedicated to specific customers), which are strategically distributed across South America, North America, Europe, Africa and Antarctica. These service centers are equipped with high-quality assets that are subject to frequent preventive maintenance to keep them in optimal condition, and we follow standard procedures for each hazardous material category in accordance with the safety guidelines set forth by the United Nations. As of December 31, 2024, we had 469 service centers across six continents.

Our service centers are linked to four regional fully automated centralized operations centers — one in Brazil operating nationwide and in Antarctica, one in Chile serving countries in Latin America other than Brazil, one in the United Kingdom serving Europe and Africa, and one in the United States serving North America. These operation centers manage emergency response services and other jobs by centralizing the strategic decisions involved in our client service processes. They are responsible for operating a 24/7/365 dedicated hotline that responds to our customers' orders for emergency response and prevention and routine services, and, when required, promptly send the appropriate commands to the service center that is closest to the location where the service will be rendered. These operations centers can track assets in real time by using geographic information system — GIS and geoprocessing tools—and therefore allow for a fast and efficient deployment of equipment and personnel to handle the relevant service.

The increase in net revenue from subscription was primarily due to the expansion of our offering in North America and Brazil segments, in which we have started or expanded our operations since 2020 through the acquisitions we completed in those regions. Such an increase is consistent with our effort to pursue our strategy to increasingly become a one-stop-shop for emergency and industrial services to our clients, seeking synergies and increasing our cross-selling abilities in all jurisdictions in which we operate.

In October 2022, in order to accelerate our growth strategy, we acquired Witt O'Brien's. As a result of this acquisition, our gross revenue derived from high impact emergencies reached R$50.7 million, as we incorporated Witt O'Brien's to our ecosystem acquiring consulting services capabilities, such as disaster mitigation, emergency preparedness and recovery, and seeking cross-selling opportunities with existing customers of Witt O'Brien's.

**Principal Factors Affecting Our Results of Operations**

We believe that the trends affecting our performance for historical periods and future periods include the following key factors:

***Delivering Organic Growth through our International Expansion and Portfolio Diversification:*** Our ability to generate strong, stable organic revenue growth across macroeconomic cycles depends on our ability to increase the breadth and depth of services that we provide to our existing customers and realize on cross-selling opportunities between our complementary service capabilities. We believe that our continued success depends on our ability to further enhance and leverage our portfolio of services offered and geographies served. We expect that our international activities will continue to grow for the foreseeable future as we continue to pursue opportunities in existing and new international markets, which will require significant dedication of management attention and financial resources. We also believe we are well positioned to respond to changing customer needs and regulatory demands in order to maintain our success, win new contracts, realize renewals or extensions of existing contracts and expand into new or adjacent markets.

***Delivering excellence and consistency through standardized training:*** We aim to deliver consistently excellent services regardless of the services offered or geographies served. Our offer of a diversified training portfolio focuses on emergency services and occupational safety and health. We have invested in training centers located in the United States, Chile, Peru, and in Brazil, where we own and operate the largest center of multimodal training in Latin America. We believe that delivering high quality, standardized training throughout our network will allow us to promote personnel qualifications, ensure quality and safety in processes with a highly qualified technical team, allowing to leverage our scalable capabilities to deliver operational and financial synergies. This includes using the capacity of our existing facilities, technology processes and people to support future growth, provide economies of scale and constantly update our training and services protocol to new industrial processes, and hazardous materials, which are constantly evolving as manufacturing processes worldwide evolve.

In addition, other significant factors affecting our performance and results of our operations include:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Our ability to attract new clients and our ability to retain existing clients, as well as to increase our net revenue from existing clients pursuant to the expansion of services provided to them;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Our ability to expand and deepen the quality, range and diversity of our portfolio of service offerings while maintaining excellent quality standards;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Our ability to maintain favorable pricing;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Our ability to comply with environmental regulations and hazardous materials, at a local, national and international level;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Our ability to maintain and strengthen a strong brand and corporate reputation;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• The impact of natural disasters or health epidemics/pandemics

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Economic growth rates in the industries and countries in which our clients operate, as well as their impact on our clients' expenditures on our services;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Wage rates and operating costs in the countries where we operate, particularly in Brazil, United States, Canada, Chile and the United Kingdom, where most of our employees are based;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Changes in foreign exchange rates, particularly fluctuations in exchange rates between the Brazilian real and the other currencies in which our subsidiaries operate; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• The level of our outstanding indebtedness and fluctuations in benchmark interest rates in Brazil, which affect our interest expenses on our real-denominated floating rate debt and financial income on our cash and cash equivalents.

**Principal Components of Our Statement of Income**

The following is a summary of the principal line items comprising consolidated statement of income.

***Net Revenue***

We provide emergency services within three business units, namely (i) Subscription; (ii) Field Services, Maintenance & Routine Emergency; and (iii) High Impact Emergency. Our net revenue is generated from services at customer sites or other locations. Our 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. We recognize net revenue for these services over time, as the customer receives and consumes the benefits of the services as they are being performed and we have a right to payment for performance completed to date. We use the input method to recognize revenue over time, based on time and materials incurred. The duration of such services can be over a number of hours, several days or even months for larger scale projects.

***Cost of services rendered***

Our cost of services rendered consist primarily of expenses related to personnel and labor, fuel, third-party services, depreciation and amortization, rent, materials and maintenance, travel, marketing, among others.

***Operating Expenses***

Our operating expenses consist primarily of expenses related to selling, general and administrative expenses, as personnel and labor, fuel, third-party services, travel and marketing, among others.

***Net finance cost/revenue***

Net finance cost/revenue consist of finance income and finance costs. Finance income consists primarily of interest earned from financial investments, foreign exchange gains and other financial income. Finance costs are primarily comprised of interests on loans, payment of interest, foreign exchange losses and financial transaction tax.

***Income tax and social contribution***

Provision for income tax and social contribution consists primarily of current and deferred income tax and social contribution. The provision for income tax and social contribution is calculated based on tax laws enacted or substantively enacted at the end of the reporting period in the countries in which we operate and generate taxable income.

**Our Segments**

Our business operations are organized in one operating and reporting segment, and our revenue is divided into four geographic segments, which correspond to the principal regions in which we operate: Brazil, Latin America (other than Brazil), Europe and North America. As of December 31, 2024, our most significant segment was Brazil, representing 46.3% of our net revenue (compared to 36.1% for the year ended December 31, 2023), followed by North America, representing 41.9% of our net revenue (compared to 50.8% for the year ended December 31, 2023), Europe, representing 6.2% of our net revenue (compared to 5.8% for the year ended December 31, 2023) and Latin America (other than Brazil), representing 5.6% of our net revenues (compared to 7.3% for the year ended December 31, 2023).

For additional information on our segment reporting see notes 3.16 and 18 of our audited Consolidated Financial Statements included elsewhere in this annual report.

**Non-GAAP Financial Measures**

This annual report presents our EBITDA, EBITDA Margin, ROIC, Free Cash Flow and Cash Conversion Rate for the convenience of the investors. EBITDA, EBITDA Margin, ROIC, Free Cash Flow and Cash Conversion Rate are non-GAAP financial measures. A non-GAAP financial measure is generally defined as a numerical measure of historical or future financial performance, financial position, or cash flow that excludes or includes amounts that would not be adjusted in the most comparable IFRS measure.

We use these non-GAAP financial measures for decision-making purposes and to assess our financial and operating performance, generate future operating plans and make strategic decisions regarding the allocation of capital. We believe that the disclosure of our non-GAAP measures provides useful supplemental information to investors and financial analysts and other interested parties in their review of our operating performance. Additionally, we believe that non-GAAP financial information, when taken collectively, may be helpful to investors because it provides consistency and comparability with past financial performance and facilitates period-to-period comparisons of results of operations. The non-GAAP financial measures described in this annual report are not a substitute for the IFRS measures of earnings.

Additionally, our calculations of EBITDA, EBITDA Margin, ROIC, Free Cash Flow and Cash Conversion Rate may be different from the calculation used by other companies, including our competitors in the industry, and therefore, our measures may not be comparable to those of other companies. For a reconciliation of EBITDA, EBITDA Margin, ROIC, Free Cash Flow and Cash Conversion Rate to the most directly comparable IFRS measure, see "— *Reconciliation of Non-GAAP Financial Measures*."

(1)For convenience purposes only, certain amounts in reais have been translated to U.S. dollars using an exchange rate of R$6.1923 to US$1.00, the commercial selling rate for U.S. dollars as of December 31, 2024, as reported by the Central Bank. These translations have not been audited and should not be considered representations that any such amounts have been, could have been or could be converted at that or any other exchange rate. See "*Item 3.D. Key Information—Risk Factors—Risks Relating to the Markets Where We Operate—Exchange rate instability can harm the economy of emerging markets where we operate and, consequently, affect us.*"

(2)We calculate EBITDA as profit (loss) for the year *plus* income tax and social contribution plus net finance cost/revenue *plus* depreciation and amortization expenses, in each case for the relevant period. Our calculation of EBITDA may be different from the calculation used by other companies, including our competitors in the industry, and therefore, our measures may not be comparable to those of other companies.

(3)We calculate EBITDA Margin as EBITDA for the relevant period *divided by* net revenue for the relevant period. Our calculation of EBITDA Margin may be different from the calculation used by other companies, including our competitors in the industry, and therefore, our measures may not be comparable to those of other companies.

(4)We calculate ROIC as net operating profit after tax for the relevant period divided by invested capital. We define net operating profit after tax as operating profit for the relevant period *minus* income tax adjustment. Income tax adjustment is defined as operating profit for the relevant period multiplied by our effective tax rate for the relevant period, the numerator of which is income tax and social contribution and the denominator of which is profit before tax. We define invested capital as total shareholders' equity *minus* goodwill *minus* intangibles assets *plus* current and non-current loans and financing *plus* debentures *plus* non-current related party loans liabilities *plu*s current and non-current obligations from acquisition of investment *plus* dividend payable *minus* cash and cash equivalents *minus* non-current related party loans assets. Although ROIC is commonly used as a measure of capital efficiency, definitions of ROIC differ, and our computation of ROIC may not be comparable to other similarly titled measures of other companies.

(5)We calculate Free Cash Flow as EBITDA for the relevant period *minus* change in working capital *minus* acquisition of property, plant and equipment and intangible assets. Change in working capital is calculated as the sum of changes in current assets and liabilities affecting the cash generated from operating activities in the statements of cash flow. Our calculation of Free Cash Flow may be different from the calculation used by other companies, including our competitors in the industry, and therefore, our measures may not be comparable to those of other companies.

(6)We calculate Cash Conversion Rate as Free Cash Flow for the relevant period *divided by* EBITDA for the relevant period. Our calculation of Cash Conversion Rate may be different from the calculation used by other companies, including our competitors in the industry, and therefore, our measures may not be comparable to those of other companies.

---

(1)Net revenue derived from our operations in Antarctica is included within the Latin America segment.

(2)Net revenue derived from operations in Africa is included within the Europe segment.

Net revenue for the year ended December 31, 2024 amounted to R$3,248.4 million, compared to R$2,590.0 million in the year ended December 31, 2023, which represents an increase of R$658.4 million, or 25.4%.

The increase in net revenue was primarily due to: (1) an increase of R$128.8 million from our Subscription business unit in Brazil and increase from the High Impact Emergencies business unit of R$63.7 million in Europe; (2) an increase of R$166.2 million as a result of extraordinary income from the sale of assets and an (3) increase of R$96.5 million from Subscription and Field Services, Maintenance & Routine Emergency in our North America segment. These increases were partially impacted by an exchange variation of the U.S. dollar, Canadian dollar and the British pound against the *real*.

Cost of services rendered for the year ended December 31, 2024 amounted to R$2,769.7 million, compared to R$2,090.5 million in the year ended December 31, 2023, which represents an increase of R$679.2 million, or 32.5%. This increase was primarily due to an increase in Personnel and labor charges due to the increase of 958 employees, hiring of third parties and travel for emergency response, as partially offset by an exchange variation of the U.S. dollar, Canadian dollar and the British pound against the *real*. Cost of services represented 85.3% and 80.7% of our net revenue, respectively, in the year ended December 31, 2024 and 2023.

*Net finance cost/revenue*

Our net finance costs increased by R$107.6 million, or 42.8%, to R$359.0 million for the year ended December 31, 2024 from R$251.3 million for the year ended December 31, 2023. Finance income increased by R$190.4 million, or 437.9%, to R$233.9 million in the year ended December 31, 2024 from R$43.5 million in the year ended December 31, 2023, primarily due to an increase in foreign-exchange rate income, as partially offset by a greater average cash balance in the period which resulted in an increase in revenues from interest earning bank deposits. Our finance costs increased by R$298.1 million, or 101.1%, to R$592.9 million in the year ended December 31, 2024 from R$294.8 million in the year ended December 31, 2023 primarily due to an increase in debentures interest and interest on loans, and the borrowing under the loan agreement with Itau BBA International PLC to finance the WOB Acquisition in 2022.

This decrease was primarily due to the decrease in the provision for deferred taxes.

*Profit for the year*

As a result of the foregoing factors, our profit for the year ended December 31, 2024 amounted to R$58.8 million, compared to R$17.2 million in the year ended December 31, 2023, which represents an increase of R$41.6 million, or 241.9%. Profit represented, respectively, 1.8% and 0.7% of the net revenue for the years ended December 31, 2024 and 2023.

(1)Net revenue derived from our operations in Antarctica is included within the Latin America segment.

(2)Net revenue derived from Witt O'Brien's' operations since closing of the WOB Acquisition on October 24, 2022 is included within the North America segment.

(3)Net revenue derived from operations in Africa is included within the Europe segment.

Net revenue for the year ended December 31, 2023 amounted to R$2,590.0 million, compared to R$1,684.9 million in the year ended December 31, 2022, which represents an increase of R$905.1 million, or 53.7%.

The increase in net revenue was primarily due to: (1) the acquisitions we concluded in the North America and Brazil segments, which experienced the largest growth in the period, reaching a net revenue of R$1,314.6 million and R$936.2 million in the year ended December 31, 2023, respectively, from R$789.5 million and R$534.1 million in the year ended December 31, 2022, respectively, as a result of a wider regional reach and, consequently, an increase in the overall number of subscription contracts and spot contracts; and (2) an increase of our net revenue generated in our Latin America segment (other than Brazil) of R$2.8 million, or 1.5%, in the year ended December 31, 2023, primarily as a result of the expansion of our existing operations in Chile and Peru and the start of new operations in Colombia. These increases were partially offset by a negative effect of 3.3 percentage points on our net revenue as a result the depreciation of the U.S. dollar, Canadian dollar and the British pound against the *real*.

*Cost of services rendered*

Cost of services rendered for the year ended December 31, 2023 amounted to R$2,090.5 million, compared to R$1,337.8 million in the year ended December 31, 2022, which represents an increase of R$752.7 million, or 56.3%. This increase was primarily due to the acquisitions we completed in the period and the increase in operations, consistent with the increase in net revenue described above, as partially offset by a positive effect of 3.3 percentage point on our cost of services rendered, as a result of the appreciation of the U.S. dollar, Canadian dollar and the British pound against the *real*. Cost of services represented 80.7% and 79.4% of our net revenue, respectively, in the year ended December 31, 2023 and 2022.

*Gross profit*

Gross profit for the year ended December 31, 2023 amounted to R$499.5 million, compared to R$347.1 million in the year ended December 31, 2022, which represents an increase of R$152.4 million, or 43.9%. Gross profit represented 19.3% and 20.6% of our net revenue, respectively, for the years ended December 31, 2023 and 2022. The decrease in gross profit margin was primarily due to the increase in cost of services rendered in the year ended December 31, 2023 as a percentage of net revenue, as a result of increased costs related to third-party providers and fuel caused by inflationary cost pressure, supply chain disruptions, and increases in oil prices in the period, as well as decreased economies of scale resulting from (1) recently acquired businesses that were in the process of being integrated into our ecosystem, and (2) organic growth in markets which we had recently entered and had smaller operations. The adoption of heightened controls over our costs and expenditures following recent acquisitions helped to mitigate inflationary pressures, including by means of centralizing negotiations with suppliers at the corporate level and the renegotiation of pricing terms with suppliers, and we have been able to gradually increase prices as a way to pass on costs and improve gross profit margins. Supply chain disruptions have been mitigated through the earlier ordering of vehicles and equipment, and increasing utilization of suppliers who have more favorable delivery terms. The increase in cost of services rendered as a percentage of net revenue was partially offset primarily by a decrease in costs with personnel as a percentage of net revenue due to workforce optimization.

*Selling, general and administrative expenses*

Selling, general and administrative expenses for the year ended December 31, 2023 amounted to R$28.4 million, compared to R$26.5 million in the year ended December 31, 2022 which represents an increase of R$1.9 million, or 7.2%. Selling, general and administrative expenses represented, respectively, 1.1% and 1.6% of our net revenue in the year ended December 31, 2023 and 2022.

*Operating profit*

Operating profit for the year ended December 31, 2023 amounted to R$360.4 million, compared to R$336.7 million in the year ended December 31, 2022, which represented an increase of R$23.7 million, or 7.0%, due to the factors described above.

*Net finance cost/revenue*

Our net finance costs increased by R$147.3 million, or 141.6%, to R$251.3 million for the year ended December 31, 2023 from R$104.0 million for the year ended December 31, 2022. Finance income increased by R$33.9 million, or 353.1%, to R$43.5 million in the year ended December 31, 2023 from R$9.6 million in the year ended December 31, 2022, primarily due to an increase in foreign-exchange rate income, as partially offset by a greater average cash balance in the period which resulted in an increase in revenues from interest earning bank deposits. Our finance costs increased by R$181.3 million, or 159.7%, to R$294.8 million in the year ended December 31, 2023 from R$113.5 million in the year ended December 31, 2022 primarily due to an increase of R$36.6 million and R$27.2 million in year ended December 31, 2022 in debentures interest and interest on loans, respectively, primarily as a result of our First Issuance of Debentures in 2022, the Second Issuance of Debentures and the borrowing under the loan agreement with Itau BBA International PLC to finance the WOB Acquisition in 2022.

Profit before tax for the year ended December 31, 2023 amounted to R$109.0 million, compared to R$232.8 million in the year ended December 31, 2022, which represents a decrease of R$123.8 million, or 53.2%, due to the factors described above.

*Income tax and social contribution*

Income tax and social contribution expense for the year ended December 31, 2023 was R$91.9 million, compared to R$44.9 million in the year ended December 31, 2022, which represents an increase of R$47.0 million, or 104.7%. This increase was primarily due to the increase in the provision for deferred taxes.

*Profit for the year*

As a result of the foregoing factors, our profit for the year ended December 31, 2023 amounted to R$17.2 million, compared to R$187.9 million in the year ended December 31, 2022, which represents a decrease of R$170.7 million, or 90.8%. Profit represented, respectively, 0.7% and 11.2% of the net revenue for the years ended December 31, 2023 and 2022.

**B.Liquidity and Capital Resources**

The following discussion of our liquidity and capital resources is based on the financial information derived from our audited Consolidated Financial Statements included elsewhere in this annual report.

We regularly evaluate opportunities to enhance our financial flexibility through a variety of methods, including, without limitation, through loans and financing. As a result of any of these actions, we may be subject to restrictions and covenants in the agreements governing these transactions that may place limitations on us, and we may be required to pledge collateral to secure such instruments. See "— *Loans and financing and debenture*" for additional information.

On March 3, 2023, we consummated the previously announced Business Combination pursuant to the Business Combination Agreement. For additional information, see "—*A. Operating Results—Business Combination*." Prior to the Business Combination, our principal sources of liquidity were cash and cash equivalents and cash flow from financing activities.

Our cash and cash equivalents include cash on hand, immediate demand deposits with financial institutions and other short-term highly liquid investments, which have an immaterial risk of change in value. As of December 31, 2024 and December 31, 2023 our cash and cash equivalents amounted to R$358.4 million and R$423.3 million, respectively. Third party financing includes working capital loans, investment financing for the acquisition of heavy vehicles and machinery and fixed-rate financing agreements, as well as, for the year ended December 31, 2023 and 2024, the issuance of Debentures. As of December 31, 2024 and 2023, our current loans and financing amounted to R$212.1 million and R$84.4 million, respectively, and our current debentures amounted to R$84.1 million and R$79.7 million, respectively. During the year ended December 31, 2024 and the year ended December 31, 2023, net cash from financing activities were R$(514.1) million and R$417.3 million, respectively.

As a result of the completion of the Business Combination concluded in 2023, we raised gross proceeds of $174.2 million, of which $50.5 million were in the form of the conversion into equity of a portion of the intercompany loan provided by Ambipar pursuant to the Ambipar Intercompany Loan Agreement (without considering any payment of Business Combination related transaction expenses). Total direct transaction costs of Ambipar and HPX were approximately $18.0 million, substantially all of which will be recorded as a reduction to additional paid-in capital. We expect to incur additional annual expenses as a public company for, among other things, director fees and additional internal and external accounting, legal and administrative resources, including increased audit, legal, and filing fees. After the consummation of the Business Combination, our principal sources of liquidity remained cash and cash equivalents, including net proceeds from the Business Combination, and cash flow from financing activities.

We intend to reduce our capital expenditures, for organic uses, to support the growth in our business and operations. Our management believes that our current available cash and cash equivalents and financial investments, and the cash flows from our operating activities, will be sufficient to meet our working capital requirements and capital expenditures in the ordinary course of business for the next 12 months. This estimate is based on our current business plan and expectations and assumptions in light of current macroeconomic conditions. However, we cannot guarantee that our liquidity assumptions will prove to be correct, and we could exhaust our available financial resources sooner than we currently expect.

Our future capital requirements will depend on many factors, including our growth rate, the timing and extent of spending to support research and development efforts, the expansion of sales and marketing activities, and the cost of any future acquisitions of businesses or machinery, equipment and vehicles. In the event that additional financing is required from outside sources, we may be unable to raise the funds on acceptable terms, if at all. We may seek additional capital through equity and/or debt financings depending on market conditions, particularly if the cash generated from operating activities is not in accordance with our expectations. If we are required to raise additional funds by issuing equity securities, dilution to public shareholders would result. Any equity securities issued may also provide for rights, preferences or privileges senior to those of holders of our Class A Ordinary Shares. If we raise funds by issuing debt securities, such debt securities would have rights, preferences and privileges senior to those of holders of Class A Ordinary Shares. The terms of debt securities or borrowings could impose significant restrictions on how we hand our operations. The credit market and immediate demand deposits financial services industry have in the past, and may in the future, experience periods of uncertainty that could impact the availability and cost of equity and debt financing. In addition, our ability to raise additional capital through the sale of equity or convertible debt securities could be significantly impacted by substantial sales of our Securities by securityholders, which could result in a significant decline in the trading price of our Class A Ordinary Shares and potentially hinder our ability to raise capital at terms that are acceptable to us or at all. A significant decline in the trading price of our Class A Ordinary Shares could potentially impact our ability to use equity or convertible debt securities as consideration in acquisitions or as a potential source of liquidity for future growth.

In addition, there is no assurance that the holders of the Warrants will elect to exercise any or all of the Warrants, which could impact our liquidity position. Whether warrantholders will exercise their Warrants, and therefore the amount of cash proceeds we would receive upon exercise, is dependent upon the trading price of the Class A Ordinary Shares, the last reported sales price for which was $0.15 per share on June 23, 2025. Each Warrant became exercisable for one Class A Ordinary Share at an exercise price of $11.50, provided, however, that an effective registration statement or a valid exemption therefrom is available. Therefore, if and when the trading price of the Class A Ordinary Shares is less than $11.50, we expect that warrantholders would not exercise their Warrants. We could receive up to an aggregate of approximately $186.1 million if all of the Warrants are exercised for cash, but we would only receive such proceeds if and when the warrant holders exercise the Warrants. The Warrants may not be or remain in the money during the period they are exercisable and prior to their expiration and, therefore, it is possible that the Warrants may not be exercised prior to their maturity on March 3, 2028, even if they are in the money, and as such, may expire worthless with minimal proceeds received by us, if any, from the exercise of Warrants. To the extent that any of the Warrants are exercised on a "cashless basis," we will not receive any proceeds upon such exercise. As a result, we do not expect to rely on the cash exercise of Warrants to fund our operations. Instead, we intend to rely on other sources of cash discussed elsewhere in this annual report to continue to fund our operations.

***Net cash generated from operating activities***

Our net cash generated from operating activities increased to R$421.4 million for the year ended December 31, 2024 from R$78.5 million of net cash generated from operating activities for the year ended December 31, 2023, primarily due to the following factors:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• our profit for the year ended December 31, 2024 increased to R$58.8 million from R$17.2 million for the year ended December 31, 2023, combined with adjustments for non-cash items consisting primarily of:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(1)an increase in interest on loans and financing and exchange-rate change to a positive net cash of R$336.5 million in the year ended December 31, 2024 compared to a positive net cash of R$150.8 million in the year ended December 31, 2023, as a result of an increase in our debentures and loans and financing combined with the increase in Brazil's base interest rates in the period;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(2)an increase in depreciation and amortization to R$322.5 million in the year ended December 31, 2024 from R$181.9 million in the year ended December 31, 2023, mainly as a result of an increase of R$167.2 million in property, plant and equipment to R$954.8 million in the year ended December 31, 2024;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• changes in assets and liabilities resulted in a total outflow of R$191.7 million in the year ended December 31, 2024 compared to a total outflow of R$71.2 million for the year ended December 31, 2023, resulting primarily as a result of:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(1)a decrease in accounts receivables by R$24.0 million for the year ended December 31, 2024 compared to a decrease by R$4.4 million for the year ended December 31, 2023, primarily as a result of our focus to return to normalized payment schedules in the year ended December 31, 2024; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(2)a decrease in suppliers of R$29.6 million for the year ended December 31, 2024, compared to an increase of R$56.3 million for the year ended December 31, 2023, in each case primarily as the result of the growth of our operations and the return to normal payment schedules to our suppliers following stabilization;

as partially offset by:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(1)a decrease in taxes payable of R$42.4 million for the year ended December 31, 2024, compared to a decrease of R$44.7 million for the year ended December 31, 2023, primarily as the result of an increase in net income before income and social contribution taxes;

***Net cash (used in) generated from financing activities***

Our net cash used in financing activities increased to R$(514.1) million for the year ended December 31, 2024 from R$417.3 million of net cash generated from financing activities for the year ended December 31, 2023, primarily due to (1) an increase to R$153.7 million for the year ended December 31, 2024 from R$124.3 million for the year ended December 31, 2023 in proceeds from loans and financing and (2) a decrease in funding of our Debentures, as offset by an increase to R$113.7 million for the year ended December 31, 2024, from R$98.2 million for the year ended December 31, 2023, in cash generated from financing received from related parties, primarily Ambipar. For more information, see "*Item 7.B. Major Shareholders and Related Party Transactions—Related Party Transactions*."

Our net cash generated from financing activities decreased to R$417.3 million for the year ended December 31, 2023 from R$994.7 million of net cash generated from financing activities for the year ended December 31, 2022, primarily due to (1) a decrease to R$124.3 million for the year ended December 31, 2023 from R$446.9 million for the year ended December 31, 2022 in proceeds from loans and financing and (2) a decrease in funding of our Debentures, as offset by an increase to R$98.2 million for the year ended December 31, 2023, from R$71.0 million for the year ended December 31, 2022, in cash generated from financing received from related parties, primarily Ambipar. For more information, see "*Item 7.B. Major Shareholders and Related Party Transactions—Related Party Transactions*."

**Capital Expenditure**

Our capital expenditures are related primarily to (1) purchasing equipment and technology or (2) acquisition of companies.

For the years ended December 31, 2024, 2023, 2022, our total capital expenditures amounted to R$134.7 million, R$287.4 million R$1,320.8 million, respectively, representing 4.1%, 11.1% and 78.4% of our net revenue respectively. We divide our capital expenditures in two categories: (1) cash spent on companies' acquisitions; net of cash received, was nil for the year ended December 31, 2024, from R$47.1 million for the year ended December 31, 2023, and R$1,090.0 million for the year ended December 31, 2022; (2) acquisition of property, plant and equipment and intangible assets amounting to and R$134.7 million for the year ended December 31, 2024 from R$236.2 million for the year ended December 31, 2023, and R$135.0 million for the year ended December 31, 2022.

We expect to maintain the amount of our capital expenditures for 2025 at the same level of 2024 to support the organic growth in our business and operations. Our management believes that the proceeds from our current available cash and cash equivalents and financial investments, and the cash flows from our operating activities, will be sufficient to meet our capital expenditures in the ordinary course of business for the next 12 months. This estimate is based on our current business plan and expectations and assumptions in light of current macroeconomic conditions. However, we cannot guarantee that our liquidity assumptions will prove to be correct, and we could exhaust our available financial resources sooner than we currently expect. Our future capital requirements will depend on several factors, including those described above in "*— Liquidity and Capital Resources*" as well as in "*Item 3.D. Key Information—Risk Factors*" in this annual report.

**Loans and financing and Debentures**

As of December 31, 2024, we had R$463.9 million in outstanding debentures (compared to R$545.8 million as of December 31, 2023) and R$990.1 million in outstanding loans and financing (compared to R$701.9 million as of December 31, 2023).

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• the development of new software, such as our Integrated Environmental Management System (SIGA — *Sistema Integrado de Gerenciamento Ambiental*), which was developed in-house;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• the research of innovative and technological equipment with specific features, including safety equipment; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• the creation of new solutions.

For example, our team has recently developed a portfolio of products used in environmental emergencies and accident prevention services in order to reduce environmental impacts and preserve the environment.

These products include an absorbent peat made of hydrophobic material for the absorption of petroleum and derivative liquids, which is highly resistant, easy to apply, has greater absorption capacity than similar products in the market, is not toxic or flammable, and has an indeterminate lifespan.

In the years ended December 31, 2024, 2023 and 2022, we paid an aggregate of R$50.4 million, R$77.3 million and R$35.3 million, respectively, in cash compensation to our executive officers and directors.

There was no amount set aside for pension, retirement or similar benefits during such period.

**Omnibus Incentive Plan**

We currently maintain an Omnibus Incentive Plan governed by the laws of the Cayman Islands for our service providers and our subsidiaries.

The Omnibus Incentive Plan gives us the ability to grant various forms of awards, including without limitation non-qualified stock options ("Options") and performance-based restricted stock units ("PSUs"). Initial grants for employees are expected to be a combination of Options (with an exercise price at fair market value on the date of grant) and PSUs.

The Options will vest over three years, with 1/3 of the option shares subject to the grant vesting on each anniversary of grant, in each case subject to continued employment on the applicable vesting date.

The PSUs are subject to a performance-based vesting based on a cumulative EBITDA target over the three-year post-Closing period from 2024 to 2026. Vesting is subject to continued employment through the last day of the performance period, or as otherwise determined in the grant agreements.

The Omnibus Incentive Plan does not grant automatic acceleration of awards due to a change in control.

Grantees are subject to customary restrictive covenants in connection with each grant. A breach of these restrictive covenants will result in forfeiture of all awards.

As of December 31, 2024, the total pool consisted of 2,062,000 Class A Ordinary Shares. No Options nor PSUs have been awarded under the Omnibus Incentive Plan.

**Indemnification Agreements**

We have entered into indemnification agreements with our directors and executive officers. The indemnification agreements and our Articles will require us to indemnify our directors and executive officers to the fullest extent permitted by law in connection with claims made by reason of their being a director or officer, as applicable, of the Company.

**C.Board Practices**

**Duties of Directors**

Under Cayman Islands law, our directors owe fiduciary duties to us, including a duty of loyalty, a duty to act honestly, and a duty to act in what they consider in good faith to be in our best interests. Our directors also have a duty to exercise their powers only for a proper purpose, a duty to avoid conflicts of interest and of duty, a duty to disclose personal interest in contracts involving us, a duty not to make secret profits from the directors' office and a duty to act with skill, care and diligence. Our directors are required to exercise the skills they actually possess and such care and diligence that a reasonably prudent person would exercise in comparable circumstances. In fulfilling their duty of care to us, our directors must ensure compliance with our Articles, as amended and restated from time to time, and the rights vested thereunder in the holders of the shares. We have the right to seek damages if a duty owed by our directors is breached. In certain limited exceptional circumstances, one or more shareholders may have the right to seek damages in our name if a duty owed by our directors is breached.

**A.Major Shareholders**

The following table sets forth information known to us regarding the beneficial ownership our Ordinary Shares as of December 31, 2024:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• each person known by us to beneficially own more than 5% of our issued and outstanding Ordinary Shares;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• each of our directors and executive officers; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• all our directors and executive officers as a group.

Beneficial ownership is determined according to the rules of the SEC, which generally provide that a person has beneficial ownership of a security if he, she or it possesses sole or shared voting or investment power over that security, including options and warrants that are currently exercisable or exercisable within 60 days. Such securities, however, are deemed to be outstanding only for the purpose of computing the percentage beneficial ownership of that person but are not deemed to be outstanding for the purpose of computing the percentage beneficial ownership of any other person. Under these rules, more than one person may be deemed to be a beneficial owner of the same securities.

As of December 31, 2024, there were 16,195,105 Class A Ordinary Shares, 39,234,746 Class B Ordinary Shares and 16,180,000 Warrants issued and outstanding. Pursuant to our Articles, each holder of Class A Ordinary Shares is entitled to one vote per share and each holder of Class B Ordinary Shares is entitled to 10 votes per share on all matters submitted to them for a vote on all Ordinary Shares voting together as a single class. The Warrants, which entitle the holder to purchase one Class A Ordinary Share at an exercise price of $11.50 per share, became exercisable on April 2, 2023, which is 30 days after the completion of the Business Combination, provided, however, that an effective registration statement or a valid exemption therefrom is available.

The expected beneficial ownership percentages set forth below do not take into account up to 11,000,000 Earn-Out Shares that may be issued to Ambipar, but do take into account the Class A Ordinary Shares underlying the Warrants.

Unless otherwise indicated, we believe that all persons named in the table below have sole voting and investment power with respect to all Ordinary Shares beneficially owned by them.

To our knowledge, other than as disclosed in this annual report and our other filings with the SEC, there has been no significant change in the percentage ownership held by any major shareholder since Closing of the Business Combination.

Any number of Warrants or additional Class A Ordinary Shares issued to any PIPE Investors, Non-Redeeming Shareholders or the XP Non-Redeeming Shareholder pursuant to any of the Subscription Agreements, the Cygnus Subscription Agreement or the Non-Redemption Agreements, as the case may be, would be equally deducted from the number of HPX Class A Ordinary Shares or HPX Private Warrants, as applicable, issued to the Sponsor in connection with the Sponsor Recapitalization.

***Voting and Support Agreement***

Concurrently with the execution and delivery of the Business Combination Agreement, Ambipar and HPX entered into the Voting and Support Agreement, pursuant to which Ambipar agreed, among other things, (i) prior to the termination of the Voting and Support Agreement, to vote to approve the Mergers, the adoption of the transactions and such other actions as contemplated in the Business Combination Agreement for which the approval of Ambipar was required and (ii) to certain transfer restrictions on its equity interests in Emergencia, us and Merger Sub for the period prior until the earlier of the Closing or the termination of the Business Combination Agreement in accordance with its terms, subject to certain limited exceptions.

**Investor Rights Agreement**

In connection with the consummation of the Business Combination Agreement, we, the Sponsor, Ambipar, Opportunity Agro Fund, the Insiders and Rafael Salvador Grisolia entered into the Investor Rights Agreement pursuant to which certain holders of registrable Securities are able to make a written demand for registration under the Securities Act of all or a portion of their registrable Securities, subject to certain limitations, so long as such demand includes a number of registrable Securities with a total offering price in excess of $75,000,000, net of all underwriting discounts and commissions. Any such demand may be in the form of an underwritten offering, it being understood that, subject to certain exceptions, we shall not be required to conduct more than an aggregate total of eight underwritten offerings or an aggregate of four underwritten offerings in any 12-month period. In addition, certain holders of registrable Securities have "piggy-back" registration rights to include their Securities in other registration statements of secondary offerings filed by us. We also filed with the SEC a resale shelf registration statement covering the resale of all registrable Securities.

In addition, pursuant to the Investor Rights Agreement, signatories thereof agreed to certain transfer restrictions on their respective equity interests in us, in the case of the Insiders and Rafael Salvador Grisolia, for a period of one year following the Closing Date, and, in the case of Ambipar and the Sponsor, for a period of three years following the Closing Date, in each case, subject to the following exceptions of permitted transfers (i) in the case of a transfer to a permitted transferee, if such shareholder provides written notice to us or (ii) (A) if such shareholder is an individual, by virtue of laws of descent and distribution upon the death of the individual, (B) if such shareholder is an individual, pursuant to a qualified domestic relations order, (C) pursuant to any liquidation, merger, share exchange or similar transaction (other than the Mergers) which results in all of our shareholders having the right to exchange their Ordinary Shares or other equity securities for cash, securities or other property; provided that in connection with any transfer of such securities pursuant to clause (ii) above, (x) such shareholder shall, and shall cause any such transferee of his, her or its Lock-Up Securities, to enter into a written agreement, in form and substance reasonably satisfactory to us, agreeing to be bound by the lock-up agreement prior to and as a condition to the occurrence of such transfer, and (y) that such transferee shall have no rights under the Investor Rights Agreement, unless they are a permitted transferee according to the terms of the Investor Rights Agreement, in which case, as a condition to such transfer, the transferee shall be required to become a party to the Investor Rights Agreement.

Furthermore, pursuant to the Investor Rights Agreement, our Board will establish an advisory executive committee comprised of up to four members to advise our Board, of which (i) one member will be designated by Opportunity Agro Fund, for as long as Opportunity Agro Fund is entitled under the terms of our Articles to appoint a member of the Board and effectively appoints such member; (ii) one member will be designated by the Sponsor, for as long as the Sponsor is entitled under the terms of our Articles to appoint a member of the Board and effectively appoints such member; and (iii) two members will be designated by Ambipar, for as long as Ambipar is entitled under the terms of our Articles to appoint a member of the Board and effectively appoints such member.

**Downside Protection Agreements**

In connection with the execution of the Subscription Agreements, the Cygnus Subscription Agreement and the Non-Redemption Agreements, the DPA Beneficiaries, we, Ambipar and the Sponsor entered into the Downside Protection Agreements dated as of July 5, 2023, pursuant to which the DPA Beneficiaries are provided with certain downside protection rights. Subject to the terms and conditions of the Downside Protection Agreements, the DPA Beneficiaries may receive, on a pro rata basis, an aggregate of up to 1,050,000 Class A Ordinary Shares from the Sponsor or may sell a certain number of their respective Class A Ordinary Shares to Ambipar, the Sponsor or to a third party in a block trade, in each case to occur no earlier than 30 months following the Closing, as detailed below:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Each DPA Beneficiary is only eligible to receive such downside protection if it holds, on each day beginning on the Closing Date and until the 30-month anniversary of the Closing Date (the "DPA Measurement Period"), a number of Class A Ordinary Shares representing at least 50% of the number of Class A Ordinary Shares held by such DPA Beneficiary immediately after Closing.

------

[T](#ib885b07745664dce8cc23d0d35721f6b_7)[able](#ib885b07745664dce8cc23d0d35721f6b_7)[of](#ib885b07745664dce8cc23d0d35721f6b_7)[Contents](#ib885b07745664dce8cc23d0d35721f6b_7)

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• In case an eligible DPA Beneficiary chooses to exercise its downside protection rights under the Downside Protection Agreements, (i) Ambipar is entitled to purchase from such DPA Beneficiary a number of Class A Ordinary Shares equal to the lowest number of Class A Ordinary Shares held by such DPA Beneficiary during the DPA Measurement Period (the "DPA Protected Shares"), and (ii) if Ambipar does not purchase the DPA Protected Shares, then the Sponsor is entitled either (x) to purchase from such DPA Beneficiary the DPA Protected Shares or (y) to facilitate the sale of such DPA Beneficiary's Class A Ordinary Shares and Warrants held as of the 30-month anniversary of the Closing Date in a block trade or on an underwritten basis to a third party pursuant to the terms of the Downside Protection Agreements (the "DPA Block Trade").

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• The purchase price payable by Ambipar or the Sponsor, as applicable, for the DPA Protected Shares of the relevant DPA Beneficiary is equal to an inflation-adjusted return (measured by the consumer price index) generated over the 30-month period following Closing and relative to the initial investment made by the relevant DPA Beneficiary pursuant to the relevant Subscription Agreement, Cygnus Subscription Agreement or Non-Redemption Agreement (the "DPA Guaranteed Return").

If the return generated by the block trade is below the DPA Guaranteed Return, the Sponsor is required to transfer, from the DPA Pro Rata Downside Protection Shares (as defined below) available to the relevant DPA Beneficiary, such number of shares in order for such DPA Beneficiary's return to be equal to or as close as possible to the relevant DPA Guaranteed Return.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• If neither Ambipar nor the Sponsor acquires the relevant DPA Protected Shares or if a DPA Block Trade is not consummated or available, then, pursuant to the terms and conditions of the relevant Downside Protection Agreement, the Sponsor shall transfer to the relevant DPA Beneficiary the applicable number of DPA Pro Rata Downside Protection Shares.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Under the terms of the Downside Protection Agreements, the maximum aggregate number of Class A Ordinary Shares that may be transferred by the Sponsor to the DPA Beneficiaries is 1,050,000 Class A Ordinary Shares (the "DPA Pro Rata Downside Protection Shares"), including: (i) 808,500 to Opportunity Agro Fund, (ii) 24,150 to XP Gestão de Recursos Ltda., (iii) 14,490 to Cygnus, (iv) 4,830 to Gannett Peek, (v) 9,660 to Genome, (vi) 4,830 to Tuchola Investments Inc., (vii) 9,732 to Constellation Master Fundo de Investimento de Ações, (viii) 8,163 to Constellation Qualificado Master Fundo de Investimento de Ações, (ix) 8,670 to Const Brazil US Fund LP and (x) 62,664 to XP Allocation Asset Management Ltda.

For the avoidance of doubt, we will not issue any Ordinary Shares in connection with the Downside Protection Agreements and the transactions contemplated in the Downside Protection Agreements will not have any dilutive effect on holders of Ordinary Shares.

**Indemnification Agreements**

We have entered into indemnification agreements with our directors and executive officers. The indemnification agreements and our Articles will require us to indemnify our directors and executive officers to the fullest extent permitted by law.

**Relationships with our Directors and Executive Officers**

Tercio Borlenghi Junior, our chairman, indirectly holds 39.8% of our Ordinary Shares (and 54.0% of the voting power of our outstanding Ordinary Shares).

**Related Person Transaction Policy**

We maintain a person transaction policy. This related person transaction policy requires any related party transaction (excluding related party transaction involving an amount equal or lower than $1,000,000, subject to certain exceptions) to be subject to (i) the approval of our audit committee, and (ii) for as long as Opportunity Agro Fund is entitled to appoint a member to our Board, to the unanimous approval of all non-interested members of our Board.

Furthermore, the policy outlines several categories of transactions that are expressly prohibited. These include transactions not conducted at market conditions, as well as the direct provision of loans, mutual transactions, or the provision of guarantees (endorsement/surety) to administrators, members of the fiscal, administrative, or committees (statutory or otherwise), their respective alternates, spouses, partners, descendants, and relatives up to the 2nd degree. Additionally, transactions that favor other companies within the group to the detriment of the Company, those with companies whose administrators or partners are relatives of Company employees in positions of trust, operations that do not guarantee equitable treatment to shareholders, and transactions with related parties that violate SEC rules and regulations, where applicable to the Company, are prohibited.

**C.Interests of Experts and Counsel**

Not applicable.

**Item 8. FINANCIAL INFORMATION**

**A.Consolidated Statements and Other Financial Information**

The information included under Item 18 of this annual report is referred to and incorporated by reference into this Item 8A.

**Legal and Administrative Proceedings**

From time to time, we may become involved in legal proceedings or be subject to claims arising in the ordinary course of business, including labor and civil proceedings. Regardless of the outcome, litigation can have an adverse impact on us because of defense and settlement costs, diversion of management time and resources, reputation and other factors.

We are not presently a party to any legal proceedings that, if determined adversely to us, would individually or taken together have a material adverse effect on our business, operating results, financial condition or cash flows. As of December 31, 2024, we recorded a provision for contingencies in the amount of R$0.4 million. For additional information, see note 15 to our audited Consolidated Financial Statements included elsewhere in this annual report.

**Dividends and Dividend Policy**

We have not adopted a dividend policy with respect to payments of any future dividends and have no current plans to pay dividends. The declaration, amount and payment of any future dividends on our Ordinary Shares will be at the sole discretion of the Board. The Board may take into account general and economic conditions, our financial condition and results of operations, our available cash and current and anticipated cash needs, capital requirements, contractual, legal, tax and regulatory restrictions and implications on the payment of dividends to our shareholders or by our subsidiaries to it and such other factors as the Board may deem relevant. In addition, the our ability to pay dividends is limited by the deeds governing our Debentures and certain financing agreements and may be limited by covenants of other of indebtedness that we or our subsidiaries may incur in the future. As a result, investors may not receive any return on an investment in our Ordinary Shares unless such investors sell their Ordinary Shares for a price greater than that which they paid for it.

**Certain Cayman Islands Legal Requirements Related to Dividends**

Under the Companies Act and our Articles, a Cayman Islands company may pay a dividend out of either its profit or share premium account, but a dividend may not be paid if this would result in the company being unable to pay its debts as they fall due in the ordinary course of business. According to our Articles, dividends can be declared and paid out of funds lawfully available to us, which include the share premium account. Dividends, if any, would be paid in proportion to the number of ordinary shares a shareholder holds. For further information with respect to taxes, see "*Item 10.E. Additional Information—Taxation—Certain Cayman Islands Tax Considerations*."

**B.Significant Changes**

Except as disclosed elsewhere in this annual report, we have not experienced any significant changes since the date of our audited Consolidated Financial Statements included in this annual report.

We were incorporated on May 3, 2022 as a Cayman Islands exempted company with limited liability duly registered with the Cayman Islands Registrar of Companies. Our corporate purposes are unrestricted pursuant to item 4 of our Articles, and we have the authority to carry out any object not prohibited by any law as provided by Section 7(4) of the Companies Act.

Our affairs are governed by our Articles, the Companies Act and the common law of the Cayman Islands. As provided in our Articles, subject to Cayman Islands law, we have full capacity to carry on or undertake any business or activity, do any act or enter into any transaction, and, for such purposes, full rights, powers and privileges. Our registered office is c/o CO Services Cayman Limited, P.O. Box 10008, Willow House, Cricket Square, Grand Cayman, KY1-1001, Cayman Islands, and our principal executive office is Avenida Angélica, 2346, 5th Floor, São Paulo, São Paulo, Brazil, 01228-200.

[T](#ib885b07745664dce8cc23d0d35721f6b_7)[able](#ib885b07745664dce8cc23d0d35721f6b_7)[of](#ib885b07745664dce8cc23d0d35721f6b_7)[Contents](#ib885b07745664dce8cc23d0d35721f6b_7)

**Description of Share Capital**

Our Articles authorize the following classes of shares: (i) Class A Ordinary Shares, which are entitled to one (1) vote per share, (ii) Class B Ordinary Shares, which are entitled to ten (10) votes per share, and (iii) such class or classes (howsoever designated) having the rights as the Board may determine from time to time. Any holder of Class B Ordinary Shares may convert his or her shares at any time into Class A Ordinary Shares on a share-for-share basis, in the manner contemplated in our Articles. The rights of the two existing classes of Ordinary Shares are otherwise identical, except with respect to voting, conversion and transfer restriction applicable to Class B Ordinary Shares as described below. See "—*Anti-Takeover Provisions in our Articles of Association—Two Classes of Ordinary Shares*."

As of the date of this annual report, our share capital is US$50,000 divided into 500,000,000 shares of a nominal or par value of US$0.0001 each.

Our authorized share capital is US$50,000 consisting of 500,000,000 shares of a nominal or par value of US$0.0001 each, which is comprised of: (i) 250,000,000 Class A Ordinary Shares; (ii) 150,000,000 Class B Ordinary Shares; and (iii) 100,000,000 shares of such class or classes (howsoever designated) and having the rights as the Board may determine from time to time in accordance with our Articles.

All of the issued and outstanding Ordinary Shares are fully paid and non-assessable. Certificates (to the extent any are issued) representing the issued and outstanding Ordinary Shares are generally not issued and legal title to the issued shares is recorded in fully registered, book-entry form in the register of members. Holders of Ordinary Shares have no redemption rights.

Each Class B Ordinary Share is convertible into one Class A Ordinary Share (as adjusted for share split, share combination and similar transactions occurring), whereas Class A Ordinary Shares are not convertible into Class B Ordinary Shares under any circumstances. Holders of Class B Ordinary Shares have the right to require that their Class B Ordinary Shares be converted into Class A Ordinary Shares, at any time after issue and without payment of any additional sum. A Class B Ordinary Share shall automatically convert into a Class A Ordinary Share upon the registration of any transfer of such Class B Ordinary Share, with certain exceptions.

For so long as Opportunity Agro Fund has the right to designate a director to our Board, we shall not issue any preference shares to a person on any terms unless we have made an offer to Opportunity Agro Fund to issue to Opportunity Agro Fund, on the same or more favorable economic terms as those terms applying to the applicable proposed issuance of preference shares, a number of preference shares equal to the product of (i) the number of preference shares to be issued and (ii) a fraction (x) the numerator of which is the Class A Ordinary Shares then held by Opportunity Agro Fund and (y) the denominator of which is all of the then issued and outstanding Class A Ordinary Shares and Class B Ordinary Shares as a single class.

We shall not issue Class A Ordinary Shares to a person on any terms unless: (a) we have made an offer to each person who holds Class B Ordinary Shares to issue to such person, on the same or more favorable economic terms as those terms applying to the applicable proposed issuance of Class A Ordinary Shares, such number of Class B Ordinary Shares as would ensure that the proportion in nominal value of the issued Ordinary Shares held by such person as Class B Ordinary Shares after the issuance of such Class A Ordinary Shares will be as nearly as practicable equal to the proportion in nominal value of the issued Ordinary Shares held by such person as Class B Ordinary Shares before the said issuance; and (b) the period during which any such offer may be accepted has expired or we have received notice of the acceptance or refusal of every offer so made.

*Register of members*

Our Class A Ordinary Shares are held through DTC, and DTC or Cede & Co., as nominee for DTC, recorded in the register of members as the holder of our Class A Ordinary Shares.

------

[T](#ib885b07745664dce8cc23d0d35721f6b_7)[able](#ib885b07745664dce8cc23d0d35721f6b_7)[of](#ib885b07745664dce8cc23d0d35721f6b_7)[Contents](#ib885b07745664dce8cc23d0d35721f6b_7)

Under Cayman Islands law, we must keep a register of members (i.e., its shareholders) that includes:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• the names and addresses of the members, a statement of the shares held by each member, and of the amount paid or agreed to be considered as paid, on the shares of each member, the number and category of shares held by each member, whether each relevant category of shares held by a member carries voting rights under the articles of association of the company, and if so, whether such voting rights are conditional;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• the date on which the name of any person was entered on the register as a member; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• the date on which any person ceased to be a member.

Under Cayman Islands law, the register of members is prima facie evidence of the matters set out therein (i.e., the register of members will raise a presumption of fact on the matters referred to above unless rebutted) and a shareholder registered in the register of members is deemed as a matter of Cayman Islands law to have prima facie legal title to the shares as set against its name in the register of members.

If the name of any person is incorrectly entered in or omitted from the register of members, or if there is any default or unnecessary delay in entering on the register the fact of any person having ceased to be a member of the company, the person or shareholder aggrieved (or any shareholder of the company or the company itself) may apply to the Cayman Islands Grand Court for an order that the register be rectified. However, there are certain limited circumstances where an application may be made to a Cayman Islands court for a determination on whether the register of members reflects the correct legal position. Further, the Cayman Islands court has the power to order that the register of members maintained by a company should be rectified where it considers that the register of members does not reflect the correct legal position. If an application for an order for rectification of the register of members were made in respect of our Ordinary Shares, then the validity of such shares may be subject to re-examination by a Cayman Islands court.

*Issuance of Shares*

Except as expressly provided in our Articles and with due regard to Opportunity Agro Fund's right to be issued preference shares as described below in "—Preferred Shares," our Board has general and unconditional authority to allot, grant options over, offer or otherwise deal with or dispose of any unissued shares in our capital without the approval of the shareholders (whether forming part of the original or any increased share capital), either at a premium or at par, with or without preferred, deferred or other special rights or restrictions, whether in regard to dividend, voting, return of capital or otherwise and to such persons, on such terms and conditions, and at such times as the Board may decide, but so that no share shall be issued at a discount, except in accordance with the provisions of the Companies Act. In accordance with our Articles and the Companies Act, we shall not issue bearer shares.

Our Articles provide that at any time that there are Class A Ordinary Shares in issue, additional Class B Ordinary Shares may only be issued pursuant to (1) a share split, subdivision of shares or similar transaction or where a dividend or other distribution is paid by the issue of shares or rights to acquire shares or following capitalization of profits; (2) a merger, consolidation, or other business combination involving the issuance of Class B Ordinary Shares as full or partial consideration; or (3) an issuance of Class A Ordinary Shares, whereby holders of Class B Ordinary Shares are entitled to purchase a number of Class B Ordinary Shares that would allow them to maintain their proportional ownership interest in the company. In light of: (a) the above provisions; (b) the fact that future transfers by holders of Class B Ordinary Shares will generally result in those shares converting to Class A Ordinary Shares, subject to limited exceptions as provided in the Articles; and (c) the ten-to-one voting ratio between our Class B Ordinary Shares and Class A Ordinary Shares, means that holders of our Class B Ordinary Shares will in many situations continue to maintain control of all matters requiring shareholder approval. This concentration of ownership and voting power will limit or preclude investors' ability to influence corporate matters for the foreseeable future.

Our Articles also provide that the issuance of non-voting ordinary shares requires the affirmative vote of a majority of the of then-outstanding Class A Ordinary Shares.

*Dividends*

We have not adopted a dividend policy with respect to payments of any future dividends. Subject to the Companies Act, our shareholders may, by resolution passed by a simple majority of the voting rights entitled to vote at a general meeting, declare dividends (including interim dividends) to be paid to shareholders but no dividend shall be declared in excess of the amount recommended by the Board. The Board may also declare dividends.

Dividends may be declared and paid out of funds lawfully available to us. Except as otherwise provided by the rights attached to shares and the Articles, all dividends shall be paid in proportion to the number of Class A Ordinary Shares or Class B Ordinary Shares a shareholder holds at the date the dividend is declared (or such other date as may be set as a record date); but, (1) if any share is issued on terms providing that it shall rank for dividend as from a particular date, that share shall rank for dividend accordingly; and (2) where we have shares in issue which are not fully paid up (as to par value) we may pay dividends in proportion to the amounts paid up on each share.

The holders of Class A Ordinary Shares and Class B Ordinary Shares shall be entitled to share equally in any dividends that may be declared in respect of Ordinary Shares from time to time. In the event that a dividend is paid in the form of Class A Ordinary Shares or Class B Ordinary Shares, or rights to acquire Class A Ordinary Shares or Class B Ordinary Shares, (1) the holders of Class A Ordinary Shares shall receive Class A Ordinary Shares, or rights to acquire Class A Ordinary Shares, as the case may be; and (2) the holders of Class B Ordinary Shares shall receive Class B Ordinary Shares, or rights to acquire Class B Ordinary Shares, as the case may be.

*Voting Rights*

The holders of the Class A Ordinary Shares and Class B Ordinary Shares have identical rights, except that: (1) the holder of Class B Ordinary Shares is entitled to ten (10) votes per share, whereas holders of Class A Ordinary Shares are entitled to one (1) vote per share; (2) Class B Ordinary Shares have certain conversion rights; and (3) holders of Class B Ordinary Shares are subject to transfer restrictions as set forth in the Articles. For more information see "—*Conversion*." The holders of Class A Ordinary Shares and Class B Ordinary Shares vote together as a single class on all matters (including the election of directors) submitted to a vote of shareholders, except as provided below and as otherwise required by law.

Our Articles provide as follows regarding the respective rights of holders of Class A Ordinary Shares and Class B Ordinary Shares:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• class consents in writing from the holders of two-thirds of the issued Class A Ordinary Shares or Class B Ordinary Shares, as applicable, shall be required for any variation to the rights attached to their respective class of shares or with the sanction of a special resolution passed at a separate general meeting of the holders of the shares of that class; however, the directors may treat any two or more classes of shares as forming one class if they consider that all such classes would be affected in the same way by the proposal;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• the rights conferred on holders of Class A Ordinary Shares shall not be deemed to be varied by the creation or issue of further Class B Ordinary Shares and vice versa;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• the rights attaching to the Class A Ordinary Shares and the Class B Ordinary Shares shall not be deemed to be varied by the creation or issue of shares with preferred or other rights, including, without limitation, shares with enhanced or weighted voting rights;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• subject to the rights of appointment and removal set forth in the Articles, our Board shall consist of such number of directors as a majority of the directors then in office may determine from time to time, provided that, unless otherwise determined by the shareholders acting by special resolution, with the approval by vote or written consent of the holders of a majority of the voting power of Class A Ordinary Shares then outstanding voting exclusively and as a separate class, the Board shall consist of not less than five (5) directors and not more than eleven (11) directors;

For the avoidance of doubt, the Articles refer to and include only economic rights;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• the approval by vote or written consent of the holders of a majority of the voting power of the Class A Ordinary Shares then outstanding, voting exclusively and as a separate class, shall be required to amend the Articles in the event such amendment would adversely affect the rights of the holders of the Class A Ordinary Shares or otherwise have an adverse effect on such rights; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• at any time when there are Class A Ordinary Shares in issue, Class B Ordinary Shares may only be issued pursuant to: (i) a share-split, subdivision or similar transaction or as contemplated in subdivision of shares or capitalization of undivided profits, in each case pursuant to the Articles; (ii) a business combination involving the issuance of Class B Ordinary Shares as full or partial consideration; and (iii) an issuance of Class A Ordinary Shares, whereby holders of Class B Ordinary Shares are entitled to purchase a number of Class B Ordinary Shares that would allow them to maintain their proportional ownership interest in us pursuant to the relevant terms of the Articles.

As set forth in the Articles, the holders of Class A Ordinary Shares and Class B Ordinary Shares, respectively, do not have the right to vote separately if the number of authorized shares of such class is increased or decreased. Rather, the number of authorized shares may be increased by the affirmative vote of the holders of a majority of the voting power of the issued and outstanding Class A Ordinary Shares and Class B Ordinary Shares, voting together in a general meeting. A two-thirds majority of the votes of shareholders, voting in a special resolution, is required to reduce our share capital.

*Preemptive or Similar Rights*

The Class A Ordinary Shares and Class B Ordinary Shares are not entitled to preemptive rights upon transfer and are not subject to conversion (except as described below under "—Conversion"), redemption or sinking fund provisions.

*Conversion*

The outstanding Class B Ordinary Shares are convertible at any time as follows: (1) at the option of the holder; and (2) on the election of the holders of a majority of the then issued and outstanding Class B Ordinary Shares, in each case, each Class B Ordinary Share of the applicable holder(s) shall be converted into one Class A Ordinary Share.

In addition, each Class B Ordinary Share will convert automatically into one Class A Ordinary Share upon: (1) any transfer, whether or not for value, except for certain transfers described in the Articles; or (2) if, at any time, the total number of the issued and outstanding Class B Ordinary Shares represents less than 10% of the total number of shares outstanding. For the avoidance of doubt, the creation of any pledge, charge, encumbrance or other security interest or third-party right of whatever description on any Class B Ordinary Shares to secure a holder's contractual or legal obligations shall not be deemed to be a transfer unless and until any such pledge, charge, encumbrance or other third-party right is enforced and results in such third party (or its nominee) holding legal title to the related Class B Ordinary Shares.

*Equal Status*

Except as expressly provided in the Articles, Class A Ordinary Shares and Class B Ordinary Shares have the same rights and privileges and rank equally, share proportionally and are identical in all respects as to all matters. In the event of any merger, consolidation, scheme, arrangement or other business combination requiring the approval of the shareholders entitled to vote thereon (whether or not we are the surviving entity), the holders of Class A Ordinary Shares shall have the right to receive, or the right to elect to receive, the same form of consideration as the holders of Class B Ordinary Shares, and the holders of Class A Ordinary Shares shall have the right to receive, or the right to elect to receive, at least the same amount of consideration at a per share basis as the holders of Class B Ordinary Shares. In the event of any: (1) tender or exchange offer to acquire any Class A Ordinary Shares or Class B Ordinary Shares by any third-party pursuant to an agreement to which we are a party; or (2) any tender or exchange offer by us to acquire any Class A Ordinary Shares or Class B Ordinary Shares, the holders of Class A Ordinary Shares shall have the right to receive, or the right to elect to receive, the same form of consideration as the holders of Class B Ordinary Shares, and the holders of Class A Ordinary Shares shall have the right to receive, or the right to elect to receive, at least the same amount of consideration at a per share basis as the holders of Class B Ordinary Shares.

*Record Dates*

For the purpose of determining shareholders entitled to notice of, or to vote at any general meeting of shareholders or any adjournment thereof, or shareholders entitled to receive dividend or other distribution payments, or in order to make a determination of shareholders for any other purpose, our Board may set a record date which shall not exceed forty (40) clear days prior to the date where the determination will be made.

*General Meetings of Shareholders*

As a condition of admission to a shareholders' meeting, a shareholder must be duly registered as our shareholder at the applicable record date for that meeting and, in order to vote, all calls or installments then payable by such shareholder to us in respect of the shares that such shareholder holds must have been paid.

Subject to any special rights or restrictions as to voting then attached to any shares, at any general meeting every shareholder who is present in person or by proxy (or, in the case of a shareholder being a corporation, by its duly authorized representative not being himself or herself a shareholder entitled to vote) shall have one (1) vote per Class A Ordinary Share and ten (10) per Class B Ordinary Share.

As a Cayman Islands exempted company, we are not obliged by the Companies Act to hold annual general meetings; however, the Articles provide that in each year we will hold an annual general meeting of shareholders, at a time determined by the Board. The agenda for an annual general meeting of shareholders will only include such items as have been included therein by the Board.

Also, we may, but are not required to (unless required by the laws of the Cayman Islands), hold other extraordinary general meetings during the year. General meetings of shareholders will be held where the directors so decide. To the extent permitted by law, annual general meetings may also be held virtually.

The Companies Act provides shareholders a limited right to request a general meeting and does not provide shareholders with any right to put any proposal before a general meeting in default of a company's articles of association. However, these rights may be provided in a company's articles of association. Our Articles provide that upon the requisition of one or more shareholders representing not less than one-third of the voting rights entitled to vote at general meetings, the Board will convene an extraordinary general meeting and put the resolutions so requisitioned to a vote at such meeting. The Articles provide no other right to put any proposals before annual general meetings or extraordinary general meetings.

Subject to regulatory requirements, the annual general meeting and any extraordinary general meetings must be called by not less than ten (10) clear days' notice prior to the relevant shareholders meeting and convened by a notice, as discussed below. Alternatively, upon the prior consent of all holders entitled to receive notice, with regards to the annual general meeting, and the holders of 95% in par value of the shares entitled to attend and vote at an extraordinary general meeting, that meeting may be convened by a shorter notice and in a manner deemed appropriate by those holders.

We will give notice of each general meeting of shareholders by publication on our website and in any other manner that we may be required to follow in order to comply with Cayman Islands law, the NYSE American and SEC requirements. The holders of registered shares may be given notice of a shareholders' meeting by means of letters sent to the addresses of those shareholders as registered in our shareholders' register, or, subject to certain statutory requirements, by electronic means.

Holders whose shares are registered in the name of DTC or its nominee, which we expect will be the case for substantially all holders of Class A Ordinary Shares, will not be our shareholder or our member and must rely on the procedures of DTC regarding notice of shareholders' meetings and the exercise of rights of a holder of the Class A Ordinary Shares.

A quorum for a general meeting consists of any one or more persons holding or representing by proxy not less than one-third of the aggregate voting power of all shares in issue and entitled to vote upon the business to be transacted.

A resolution put to a vote at a general meeting shall be decided on a poll. An ordinary resolution to be passed by the shareholders at a general meeting requires the affirmative vote of a simple majority of the votes cast by, or on behalf of, the shareholders entitled to vote, present in person or by proxy and voting at the meeting. A special resolution requires the affirmative vote on a poll of no less than two-thirds of the votes cast by the shareholders entitled to vote who are present in person or by proxy at a general meeting. Both ordinary resolutions and special resolutions may also be passed by a unanimous written resolution signed by all our shareholders, as permitted by the Companies Act and our Articles.

Pursuant to the Articles, general meetings of shareholders are to be chaired by the chairman of the Board or in his absence the vice-chairman of the Board. If both the chairman and vice-chairman of the Board are absent, the directors present at the meeting shall appoint one of them to be chairman of the general meeting. If neither the chairman nor another director is present at the general meeting within 15 minutes after the time appointed for holding the meeting, the shareholders present in person or by proxy and entitled to vote may elect any one of the shareholders to be chairman. The order of business at each meeting shall be determined by the chairman of the meeting, and he or she shall have the right and authority to prescribe such rules, regulations and procedures and to do all such acts and things as are necessary or desirable for the proper conduct of the meeting, including, without limitation, the establishment of procedures for the maintenance of order and safety, limitations on the time allotted to questions or comments on our affairs, restrictions on entry to such meeting after the time prescribed for the commencement thereof, and the opening and closing of the polls.

*Liquidation Rights*

If we are voluntarily wound up, the liquidator, after taking into account and giving effect to the rights of preferred and secured creditors and to any agreement between us and any creditors that the claims of such creditors shall be subordinated or otherwise deferred to the claims of any other creditors and to any contractual rights of set-off or netting of claims between us and any person or persons (including without limitation any bilateral or any multi-lateral set-off or netting arrangements between us and any person or persons) and subject to any agreement between us and any person or persons to waive or limit the same, shall apply our property in satisfaction of our liabilities *pari passu* and subject thereto shall distribute the property amongst the shareholders according to their rights and interests into the company.

*Changes to Capital*

Pursuant to the Articles, we may from time to time by ordinary resolution:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• increase our share capital by such sum, to be divided into shares of such amount, as the resolution shall prescribe;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• consolidate and divide all or any of our share capital into shares of a larger amount than our existing shares;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• convert all or any of our paid-up shares into stock and reconvert that stock into paid up shares of any denomination;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• subdivide our existing shares or any of them into shares of a smaller amount; provided, that in the subdivision the proportion between the amount paid and the amount, if any, unpaid on each reduced share shall be the same as it was in the case of the share from which the reduced share is derived; or

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• cancel any shares which, at the date of the passing of the resolution, have not been taken or agreed to be taken by any person and diminish the amount of our share capital by the amount of the shares so cancelled.

[T](#ib885b07745664dce8cc23d0d35721f6b_7)[able](#ib885b07745664dce8cc23d0d35721f6b_7)[of](#ib885b07745664dce8cc23d0d35721f6b_7)[Contents](#ib885b07745664dce8cc23d0d35721f6b_7)

Our shareholders may by special resolution, subject to confirmation by the Grand Court of the Cayman Islands on an application by the company for an order confirming such reduction, reduce our share capital or any capital redemption reserve in any manner permitted by law.

In addition, subject to the provisions of the Companies Act and our Articles, we may:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• issue shares on terms that they are to be redeemed or are liable to be redeemed;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• purchase our own shares (including any redeemable shares); and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• make a payment in respect of the redemption or purchase of our own shares in any manner authorized by the Companies Act, including out of our own capital.

*Transfer of Shares*

Subject to any applicable restrictions set forth in our Articles, any of our shareholder may transfer all or any of his or her Ordinary Shares by an instrument of transfer in the usual or common form or in the form prescribed by the NYSE American or any other form approved by the Board.

The Class A Ordinary Shares are traded on the NYSE American in book-entry form and may be transferred in accordance with the Articles and the NYSE American rules and regulations.

However, our Board may, in its absolute discretion, decline to register any transfer of any Ordinary Share that is either not fully paid up to a person of whom it does not approve or is issued under any share incentive scheme for employees which contains a transfer restriction that is still applicable to such Ordinary Share. The Board may also decline to register any transfer of any Ordinary Share unless:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• a fee of such maximum sum as the NYSE American may determine to be payable or such lesser sum as the Board may from time to time require is paid to us in respect thereof;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• the instrument of transfer is lodged at the registered office with us, accompanied by the certificate (if any) for the Ordinary Shares to which it relates and such other evidence as our Board may reasonably require to show the right of the transferor to make the transfer;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• the instrument of transfer is in respect of only one class of shares;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• the instrument of transfer is properly stamped, if required;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• the Ordinary Shares transferred are fully paid (as to both par value and any premium) and free of any lien in our favor; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• in the case of a transfer to joint holders, the transfer is not to more than four joint holders.

If the Board refuses to register a transfer they are required, within two (2) months after the date on which the instrument of transfer was lodged, to send to the transferee notice of such refusal.

*Share Repurchase*

The Companies Act and our Articles permit us to purchase our own Ordinary Shares, subject to certain restrictions. The Board may only exercise this power on our behalf, subject to the Companies Act, the Articles and to any applicable requirements imposed from time to time by the SEC, the NYSE American, or by any recognized stock exchange on which our Securities are listed.

**Board of Directors**

Subject to the provisions of the Companies Act, the Articles, to any directions given by Ordinary Resolution and to the listing rules of the NYSE American, our business shall be managed by the Directors who may exercise all our powers, including to raise capital or borrow money and to mortgage or charge all or any part of our undertaking, property and assets (present and future) and uncalled capital and, subject to the Companies Act, to issue debentures, bonds and other securities, whether outright or as collateral security for any of our debt, liability or obligation or those of any third party.

*Appointment and Removal*

We are managed by our Board. The Articles provide that, unless otherwise determined by a special resolution of shareholders with the approval by the holders of a majority of the Class A Ordinary Shares voting exclusively and as a separate class, the Board will be composed of five (5) to nine (9) directors, with the number being determined by a majority of the directors then in office. As of the date of this annual report, our Board consists of seven (7) directors and has no vacancy.

The Articles provide that directors shall be elected by an ordinary resolution of the shareholders, which requires the affirmative vote of a simple majority of the votes cast on the resolution by the shareholders entitled to vote who are present, in person or by proxy, at the meeting. Each director shall be appointed and elected for such term as the resolution appointing him or her may determine or until his or her death, resignation or removal. There is no age limit for our Directors.

Notwithstanding the foregoing, Ambipar shall be entitled to nominate a number of designees to the Board by written notice served upon the company: (1) for so long as the aggregate voting power of Class B Ordinary Shares held by Ambipar continues to be at least fifty percent (50%) of the total voting power of all shares, then Ambipar shall be entitled to nominate at least the majority of the directors; provided that at least one of such directors shall qualify as an independent director pursuant to Rule 10A-3 under the Exchange Act and shall also be appointed as a member of the audit committee; provided, further, that if more than one director nominated by Ambipar shall be appointed as a member of the audit committee, such member shall also qualify as an independent director pursuant to Rule 10A-3 under the Exchange Act should the applicable rules and regulations so require; and (2) for so long as the aggregate voting power of Class B Ordinary Shares held by Ambipar continues to be at least twenty-five percent (25%), but less than fifty percent (50%), of the total voting power of all shares, then Ambipar shall be entitled to nominate at least one-third of the directors to the Board.

For so long as the Sponsor is subject to the transfer restrictions with respect to its Class A Ordinary Shares pursuant to the terms of the Investor Rights Agreement, the Sponsor shall be entitled to nominate one director by written notice served upon us; provided that such Sponsor director shall qualify as an independent director. The Sponsor director shall also be appointed as a member of the audit committee, provided that the Sponsor director shall be considered an independent director pursuant to Rule 10A-3 under the Exchange Act.

For so long as Opportunity Agro Fund shall hold at least fifty percent (50%) of the Class A Ordinary Shares voting power held by Opportunity Agro Fund immediately after Closing, Opportunity Agro Fund shall be entitled to nominate one director by written notice served upon us.

Each of Ambipar, the Sponsor and Opportunity Agro Fund, as applicable, shall have the exclusive right to appoint and remove the respective director(s) appointed by it, and appoint replacement director(s). Any such directors shall be nominated, appointed and removed only by Ambipar, the Sponsor or Opportunity Agro Fund, as the case may be, by written notice served upon us. Such appointment or removal by Ambipar, the Sponsor or Opportunity Agro Fund, as applicable, shall have immediate effect when the notice is served, or take effect at such later time as may be stated in such notice. Any vacancies on the Board that arise other than upon the removal of a director by resolution passed at a general meeting can be filled by the remaining directors (notwithstanding that they may constitute less than a quorum). Any such appointment shall be as an interim director to fill such vacancy until the next annual general meeting of shareholders (and such appointment shall terminate at the commencement of the annual general meeting).

*Grounds for Removing a Director*

Except for directors appointed by Ambipar, the Sponsor and Opportunity Agro Fund, which may be removed by them at any time at their discretion, before the expiration of his or her term of office, a director may only be removed with or without cause by ordinary resolution in accordance with the provisions of the Articles.

The notice of the general meeting must contain a statement of the intention to remove the director and must be served on the director not less than ten (10) calendar days before the meeting. The director is entitled to attend the meeting and be heard on the motion for his removal.

The office of a director will be vacated automatically if he or she: (1) becomes prohibited by law from being a director; (2) dies or is, in the opinion of all his co-directors, incapable by reason of mental disorder of discharging his duties as director; (3) becomes bankrupt or makes an arrangement or composition with his creditors; (4) resigns his office by notice to us; or (5) has for more than six months been absent without permission of the directors from meetings of the Board held during that period, and the remaining directors resolve that his or her office be vacated.

*Director's Interest*

A Director must disclose any direct or indirect interest in any transaction or arrangement with the Company, and following a declaration being made pursuant to the Articles, subject to any separate requirement for audit committee approval under applicable law or the listing rules of the NYSE American or specific policies adopted by the Board, and unless disqualified by the chairman of the relevant meeting, a Director may vote in respect of any such transaction or arrangement in which such Director is interested and may be counted in the quorum at such meeting.

*Indemnity of Directors and Officers*

In accordance with the Articles, our directors and officers must be indemnified out of our assets and funds against any liability incurred or sustained by that director or officer as a result of any act or failure to act in carrying out their functions, except for any such liability that the director or officer may incur by reason of his own dishonesty, willful default or fraud in or about the conduct of our business or affairs (including as a result of any mistake of judgment) or in the execution or discharge of his duties, powers, authorities or discretion.

**Inspection of Books and Records**

Holders of our shares will have no general right under Cayman Islands law to inspect or obtain copies of our list of shareholders or our corporate records. However, the Board may determine from time to time whether and to what extent our accounting records and books shall be open to inspection by shareholders who are not members of the Board.

**Exempted Company**

We are an exempted company with limited liability under the Companies Act. The Companies Act distinguishes between ordinary resident companies and exempted companies. Any company that is registered in the Cayman Islands but conducts business mainly outside of the Cayman Islands may apply to be registered as an exempted company. The requirements for an exempted company are essentially the same as for an ordinary company except for the exemptions and privileges listed below:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• an exempted company does not have to file an annual return of its shareholders with the Registrar of Companies;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• an exempted company's register of members is not open to inspection;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• an exempted company does not have to hold an annual general meeting;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• an exempted company may obtain an undertaking against the imposition of any future taxation (such undertakings are usually given for 20 years in the first instance);

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• an exempted company may register by way of continuation in another jurisdiction and be deregistered in the Cayman Islands;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• an exempted company may register as a limited duration company; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• an exempted company may register as a segregated portfolio company.

"Limited liability" means that the liability of each shareholder is limited to the amount unpaid by the shareholder on the shares of the company (except in exceptional circumstances, such as involving fraud, the establishment of an agency relationship or an illegal or improper purpose or other circumstances in which a court may be prepared to pierce or lift the corporate veil).

**Anti-Takeover Provisions in Our Articles of Association**

Some provisions of the Articles of Association may discourage, delay or prevent a change in our control or management that shareholders may consider favorable. In particular, our capital structure concentrates ownership of voting rights in the hands of our controlling shareholder. These provisions, which are summarized below, are expected to discourage coercive takeover practices and inadequate takeover bids. These provisions are also designed to encourage persons seeking to acquire our control to first negotiate with the Board. However, these provisions could also have the effect of discouraging others from attempting hostile takeovers and, consequently, they may also inhibit temporary fluctuations in the market price of the Class A Ordinary Shares that often result from actual or rumored hostile takeover attempts. These provisions may also have the effect of preventing changes in our management. It is possible that these provisions could make it more difficult to accomplish transactions that shareholders may otherwise deem to be in their best interests.

*Two Classes of Ordinary Shares*

Our Class B Ordinary Shares are entitled to ten (10) votes per share, while the Class A Ordinary Shares are entitled to one (1) vote per share. Our controlling shareholder owns all of our Class B Ordinary Shares, has the ability to elect certain directors (see "—*Board of Directors—Appointment and Removal*" above) and to determine the outcome of most matters submitted for a vote of shareholders. This concentrated voting control could discourage others from initiating any potential merger, takeover, or other change of control transaction that other shareholders may view as beneficial.

So long as the controlling shareholder has the ability to determine the outcome of most matters submitted to a vote of shareholders as well as our overall management and direction, third parties may be deterred in their willingness to make an unsolicited merger, takeover, or other change of control proposal, or to engage in a proxy contest for the election of directors. As a result, the fact that we have two classes of ordinary shares may have the effect of depriving investors as a holder of Class A Ordinary Shares of an opportunity to sell their Class A Ordinary Shares at a premium over prevailing market prices and make it more difficult to replace our directors and management.

*Authorized Ordinary Shares*

Our authorized but unissued Ordinary Shares are available for future issuances without shareholder approval and could be utilized for a variety of corporate purposes, including future offerings to raise additional capital, acquisitions and employee benefit plans. The existence of authorized but unissued and unreserved Ordinary Shares could render more difficult or discourage an attempt to obtain our control by means of a proxy contest, tender offer, merger or otherwise.

*Preferred Shares*

Our Board is given wide powers to issue one or more classes or series of shares with preferred rights. Such preferences may include, for example, dividend rights, conversion rights, redemption privileges, enhanced voting powers and liquidation preferences; provided, however, that for so long as Opportunity Agro Fund has the right to designate a director to our Board, we shall not issue any preference shares to a person on any terms unless we have made an offer to Opportunity Agro Fund to issue to Opportunity Agro Fund, on the same or more favorable economic terms as those terms applying to the applicable proposed issuance of preference shares, a number of preference shares equal to the product of (i) the number of preference shares to be issued and (ii) a fraction (x) the numerator of which is the Class A Ordinary Shares then held by Opportunity Agro Fund and (y) the denominator of which is all of the then issued and outstanding Class A Shares and Class B Ordinary Shares as a single class.

Despite the anti-takeover provisions described above, under Cayman Islands law, the Board may only exercise the rights and powers granted to them under the Articles, for what they believe in good faith to be in the company's best interests.

**Protection of Non-Controlling Shareholders — Cayman Islands**

The Grand Court of the Cayman Islands may, on the application of shareholders holding not less than one fifth of our shares in issue, appoint an inspector to examine our affairs and report thereon in a manner as the Grand Court shall direct.

Subject to the provisions of the Companies Act, any shareholder may petition the Grand Court of the Cayman Islands which may make a winding up order, if the court is of the opinion that this winding up is just and equitable.

Notwithstanding the U.S. securities laws and regulations that are applicable to us, general corporate claims against us by our shareholders must, as a general rule, be based on the general laws of contract or tort applicable in the Cayman Islands or their individual rights as shareholders as established by our Articles.

The common law of the Cayman Islands is derived in part from comparatively limited judicial precedent in the Cayman Islands as well as from English common law, the decisions of whose courts are of persuasive authority but are not binding on a court in the Cayman Islands, which permit a minority shareholder to commence a representative action against us, or derivative actions in our name, to challenge: (1) an act which is ultra vires or illegal; (2) an act which constitutes a fraud against the minority and the wrongdoers themselves control us; and (3) an irregularity in the passing of a resolution that requires a qualified (or special) majority.

**Fiscal Year**

Our fiscal year begins on January 1 of each year and ends on December 31 of the same year.

**Cayman Islands Data Protection**

We have certain duties under the Data Protection Act (as amended) of the Cayman Islands (the "DPL"), based on internationally accepted principles of data privacy.

***Privacy Notice***

This privacy notice puts our shareholders on notice that through their investment in us they will provide us with certain personal information which constitutes personal data within the meaning of the DPL (the "personal data").

***Investor Data***

We will collect, use, disclose, retain and secure personal data to the extent reasonably required only and within the parameters that could be reasonably expected during the normal course of business. We will only process, disclose, transfer or retain personal data to the extent legitimately required to conduct our activities on an ongoing basis or to comply with legal and regulatory obligations to which we are subject. We will only transfer personal data in accordance with the requirements of the DPL, and will apply appropriate technical and organizational information security measures designed to protect against unauthorized or unlawful processing of the personal data and against the accidental loss, destruction or damage to the personal data.

In our use of this personal data, we will be characterized as a "data controller" for the purposes of the DPL, while our affiliates and service providers who may receive this personal data from us in the conduct of our activities may either act as our "data processors" for the purposes of the DPL or may process personal information for their own lawful purposes in connection with services provided to us.

We may also obtain personal data from other public sources. Personal data includes, without limitation, the following information relating to a shareholder and/or any individuals connected with a shareholder as an investor: name, residential address, email address, contact details, corporate contact information, signature, nationality, place of birth, date of birth, tax identification, credit history, correspondence records, passport number, bank account details, source of funds details and details relating to the shareholder's investment activity.

***Who this Affects***

If you are a natural person, this will affect you directly. If you are a corporate investor (including, for these purposes, legal arrangements such as trusts or exempted limited partnerships) that provides us with personal data on individuals connected to you for any reason in relation your investment in us, this will be relevant for those individuals and you should transmit the content of this Privacy Notice to such individuals or otherwise advise them of its content.

***How We May Use a Shareholder's Personal Data***

We may, as the data controller, collect, store and use personal data for lawful purposes, including, in particular: (1) where this is necessary for the performance of our rights and obligations under any agreements; (2) where this is necessary for compliance with a legal and regulatory obligation to which we are or may be subject (such as compliance with anti-money laundering and FATCA/CRS requirements); and/or (3) where this is necessary for the purposes of our legitimate interests and such interests are not overridden by your interests, fundamental rights or freedoms.

Should we wish to use personal data for other specific purposes (including, if applicable, any purpose that requires your consent), we will contact you.

***Why We May Transfer Your Personal Data***

In certain circumstances we may be legally obliged to share personal data and other information with respect to your shareholding with the relevant regulatory authorities such as the Cayman Islands Monetary Authority or the Tax Information Authority. They, in turn, may exchange this information with foreign authorities, including tax authorities.

We anticipate disclosing personal data to persons who provide services to us and our affiliates (which may include certain entities located outside the US, the Cayman Islands or the European Economic Area), who will process your personal data on our behalf.

***The Data Protection Measures We Take***

Any transfer of personal data by us or our duly authorized affiliates and/or delegates outside of the Cayman Islands shall be in accordance with the requirements of the DPL.

We and our duly authorized affiliates and/or delegates shall apply appropriate technical and organizational information security measures designed to protect against unauthorized or unlawful processing of personal data, and against accidental loss or destruction of, or damage to, personal data.

We shall notify you of any personal data breach that is reasonably likely to result in a risk to your interests, fundamental rights or freedoms or those data subjects to whom the relevant personal data relates.

**C.Material Contracts**

See *"Item 6.B. Directors, Senior Management and Employees — Compensation*," "*Item 7.A — Major Shareholders and Related Party Transactions*" and "*Item 7.B. Major Shareholders and Related Party Transactions—Related Party Transactions*." Except as otherwise disclosed in this annual report on Form 20-F (including the Exhibits), we are not currently, and have not been in the last two years, party to any material contract, other than contracts entered into in the ordinary course of business.

**D.Exchange Controls**

The Cayman Islands currently has no exchange control restrictions.

Certain Latin American economies in which we operate are subject to significant foreign currency exchange controls and currency devaluation. See "*Item 3.D. Key Information—Risk Factors—Risks Relating to the Markets Where We Operate—Exchange rate instability can harm the economy of emerging markets where we operate and, consequently, affect us*."

**E.Taxation**

The following summary contains a description of certain Cayman Islands and U.S. federal income tax consequences of the acquisition, ownership and disposition of our Class A ordinary shares. It does not purport to be a comprehensive description of all the tax considerations that may be relevant to a decision to purchase our Class A Ordinary Shares, is not applicable to all categories of investors, some of which may be subject to special rules, and does not address all of the Cayman Islands and U.S. federal income tax considerations applicable to any particular holder. The summary is based upon the tax laws of the Cayman Islands and the United States and regulations thereunder as of the date hereof, which are subject to change.

Prospective purchasers of our Class A Ordinary Shares should consult their own tax advisors about the particular Cayman Islands and U.S. federal, state, local and other tax consequences to them of the acquisition, ownership and disposition of our Class A Ordinary Shares.

The following summary does not address any tax consequences relating to our Warrants, and prospective purchasers of our Warrants should consult their own tax advisors about the particular tax consequences to them of the acquisition, ownership, exercise and disposition of our Warrants.

**Certain Cayman Islands Tax Considerations**

The Cayman Islands laws currently levy no taxes on individuals or corporations based upon profits, income, gains or appreciation and there is no taxation in the nature of inheritance tax or estate duty or withholding tax applicable to us or to any holder of Class A ordinary shares. There are currently no other taxes likely to be material to us levied by the government of the Cayman Islands except for stamp duties which may be applicable on instruments executed in, or after execution brought within the jurisdiction of the Cayman Islands. No stamp duty is payable in the Cayman Islands on transfers of shares of Cayman Islands companies except: (i) in respect to any transfer instrument or document to which the immediately preceding sentence applies; and (ii) in respect of shares through which an interest in land in the Cayman Islands is held. There are no exchange control regulations or currency restrictions imposed on us under Cayman Islands law.

As a Cayman Islands exempted company with limited liability, we applied for and successfully received an undertaking as to tax concessions pursuant to Section 6 of the Tax Concessions Act (Revised) of the Cayman Islands. This undertaking provides that, for a period of 20 years from the date of issue of the undertaking, no law thereafter enacted in the Cayman Islands imposing any taxes to be levied on profits, income, gains or appreciation will apply to us or our operations.

Payments of dividends and capital in respect of our Class A ordinary shares will not be subject to taxation in the Cayman Islands and no withholding tax will be required on the payment of a dividend or capital under Cayman Islands law to any holder of our Class A ordinary shares, nor will gains derived from the disposal of our Class A ordinary shares be subject to Cayman Islands income or corporation tax.

There is no income tax treaty or convention currently in effect between the United States and the Cayman Islands.

**Certain United States Federal Income Tax Considerations**

The following discussion describes certain U.S. federal income tax consequences of the ownership and disposition of our Class A Ordinary Shares. This discussion deals only with Class A Ordinary Shares that are held as capital assets by a U.S. Holder (as defined below).

As used herein, the term "U.S. Holder" means a beneficial owner of our Class A Ordinary Shares that is, for U.S. federal income tax purposes, any of the following:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• an individual who is a citizen or resident of the United States;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• a corporation (or other entity treated as a corporation for U.S. federal income tax purposes) created or organized in or under the laws of the United States, any state thereof or the District of Columbia;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• an estate the income of which is subject to U.S. federal income taxation regardless of its source; or

[T](#ib885b07745664dce8cc23d0d35721f6b_7)[able](#ib885b07745664dce8cc23d0d35721f6b_7)[of](#ib885b07745664dce8cc23d0d35721f6b_7)[Contents](#ib885b07745664dce8cc23d0d35721f6b_7)

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• a trust if it (1) is subject to the primary supervision of a court within the United States and one or more United States persons have the authority to control all substantial decisions of the trust; or (2) has a valid election in effect under applicable United States Treasury regulations to be treated as a United States person.

This discussion is based upon provisions of the Internal Revenue Code of 1986, as amended (the "Code"), and regulations, rulings and judicial decisions thereunder as of the date hereof. Those authorities may be changed, perhaps retroactively, so as to result in U.S. federal income tax consequences different from those summarized below.

This discussion does not represent a detailed description of the U.S. federal income tax consequences applicable to you if you are subject to special treatment under the U.S. federal income tax laws, including if you are:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• a dealer or broker in securities;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• a financial institution;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• a regulated investment company;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• a real estate investment trust;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• an insurance company;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• a tax-exempt organization;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• a person holding our Class A Ordinary Shares as part of an integrated or conversion transaction, a constructive sale or a straddle;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• a trader in securities that has elected the mark-to-market method of accounting for your securities;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• a person liable for alternative minimum tax;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• a person who owns or is deemed to own 10% or more of all of our outstanding stock (by vote or value);

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• a partnership or other pass-through entity for U.S. federal income tax purposes;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• a person required to accelerate the recognition of any item of gross income with respect to our Class A Ordinary Shares as a result of such income being recognized on an applicable financial statement; or

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• a person whose "functional currency" for U.S. federal income tax purposes is not the U.S. dollar.

If a partnership (or other entity or arrangement treated as a partnership for U.S. federal income tax purposes) holds our Class A Ordinary Shares, the tax treatment of a partner will generally depend upon the status of the partner and the activities of the partnership. If you are a partnership or partner of a partnership holding our Class A Ordinary Shares, you should consult your tax advisors.

This summary does not contain a detailed description of all the U.S. federal income tax consequences to you in light of your particular circumstances and does not address the Medicare tax on net investment income, U.S. federal estate and gift taxes or the effects of any state, local or non-U.S. tax laws. If you are considering the purchase of our Class A Ordinary Shares, you should consult your own tax advisors concerning the particular U.S. federal income tax consequences to you of the ownership and disposition of our Class A Ordinary Shares, as well as the consequences to you arising under other U.S. federal tax laws (such as estate and gift tax laws) and the laws of any other taxing jurisdiction.

***Taxation of Dividends***

Subject to the discussion under "—*Passive Foreign Investment Company*" below, the gross amount of distributions on our Class A Ordinary Shares will be taxable as dividends to the extent paid out of our current or accumulated earnings and profits, as determined under U.S. federal income tax principles. To the extent that the amount of any distribution exceeds our current and accumulated earnings and profits for a taxable year, the distribution will first be treated as a tax-free return of capital, causing a reduction in your tax basis in the Class A Ordinary Shares, and to the extent the amount of the distribution exceeds your tax basis, the excess will be taxed as capital gain recognized on a sale or exchange (as discussed below under "—*Taxation of Sales or Exchanges*"). We do not, however, expect to determine earnings and profits in accordance with U.S. federal income tax principles. Therefore, you should expect that a distribution will generally be reported as a dividend for U.S. federal income tax purposes.

------

[T](#ib885b07745664dce8cc23d0d35721f6b_7)[able](#ib885b07745664dce8cc23d0d35721f6b_7)[of](#ib885b07745664dce8cc23d0d35721f6b_7)[Contents](#ib885b07745664dce8cc23d0d35721f6b_7)

Any dividends that you receive will be includable in your gross income as ordinary income on the day actually or constructively received by you and, for purposes of calculating the U.S. foreign tax credit, such dividends will be treated as income from sources outside the United States and will generally constitute passive category income. Such dividends will not be eligible for the dividends received deduction allowed to corporations under the Code. Subject to applicable limitations (including a minimum holding period requirement), dividends received by non-corporate U.S. investors from a qualified foreign corporation may be treated as "qualified dividend income" that is subject to reduced rates of taxation. A foreign corporation is treated as a qualified foreign corporation with respect to dividends paid by that corporation on shares that are readily tradable on an established securities market in the United States. United States Treasury Department guidance indicates that our Class A Ordinary Shares, which are listed on the NYSE American, are readily tradable on an established securities market in the United States. Thus, we believe that any dividends we pay on our Class A Ordinary Shares to non-corporate U.S. Holders will be potentially eligible for these reduced tax rates. There can be no assurance, however, that our Class A Ordinary Shares will be considered readily tradable on an established securities market in later years. In addition, non-corporate U.S. Holders will not be eligible for reduced tax rates on any dividends received from us if we are a passive foreign investment company (as discussed below under "—*Passive Foreign Investment Company*") in the taxable year in which such dividends are paid or in the preceding taxable year. You should consult your own tax advisors regarding the application of these rules to your particular circumstances.

Distributions of Class A Ordinary Shares, or rights to subscribe for Class A Ordinary Shares, which are received as part of a *pro rata* distribution to all of our shareholders generally will not be subject to U.S. federal income tax.

***Taxation of Sales or Exchanges***

For U.S. federal income tax purposes, you will recognize taxable gain or loss on any sale, exchange or other taxable disposition of Class A Ordinary Shares in an amount equal to the difference between the amount realized for the Class A Ordinary Shares and your tax basis in the Class A Ordinary Shares. Subject to the discussion under "—*Passive Foreign Investment Company*" below, such gain or loss will generally be capital gain or loss and will generally be long-term capital gain or loss if you have held the Class A Ordinary Shares for more than one year. Long-term capital gains of non-corporate U.S. Holders (including individuals) are eligible for reduced rates of taxation. The deductibility of capital losses is subject to limitations. Any gain or loss recognized by you will generally be treated as U.S. source gain or loss.

***Passive Foreign Investment Company***

Based on the past and projected composition of our income and assets and the value of our assets, including goodwill, we do not believe we were a passive foreign investment company, or PFIC, for our most recent taxable year, and we do not expect to become a PFIC in the current taxable year or the foreseeable future, although there can be no assurance in this regard.

In general, we will be a PFIC for any taxable year in which:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• at least 75% of our gross income is passive income, or

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• at least 50% of the value (generally determined based on a quarterly average) of our assets is attributable to assets that produce, or are held for the production of, passive income

For this purpose, passive income generally includes dividends, interest, royalties and rents (other than royalties and rents derived in the active conduct of a trade or business and not derived from a related person). In addition, cash and other assets readily convertible into cash are generally considered passive assets. If we own at least 25% (by value) of the stock of another corporation, for purposes of determining whether we are a PFIC, we will be treated as owning our proportionate share of the other corporation's assets and receiving our proportionate share of the other corporation's income.

The determination of whether we are a PFIC is made annually. Accordingly, it is possible that we may become a PFIC in the current or any future taxable year due to changes in our asset or income composition. If we are or were a PFIC for any taxable year during which you hold our Class A Ordinary Shares (possibly including, for these purposes, taxable years in which you held HPX Class A Ordinary Shares (if applicable)), you will be subject to special tax rules discussed below.

------

[T](#ib885b07745664dce8cc23d0d35721f6b_7)[able](#ib885b07745664dce8cc23d0d35721f6b_7)[of](#ib885b07745664dce8cc23d0d35721f6b_7)[Contents](#ib885b07745664dce8cc23d0d35721f6b_7)

If we are a PFIC for any taxable year during which you hold our Class A Ordinary Shares and you do not make a timely mark-to-market election, as described below, you will be subject to special tax rules with respect to any "excess distribution" received and any gain realized from a sale or other disposition, including a pledge, of Class A Ordinary Shares. Distributions received in a taxable year will be treated as excess distributions to the extent that they are greater than 125% of the average annual distributions received during the shorter of the three preceding taxable years or your holding period for the Class A Ordinary Shares. Under these special tax rules:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• the excess distribution or gain will be allocated ratably over your holding period for the Class A Ordinary Shares,

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• the amount allocated to the current taxable year, and any taxable year prior to the first taxable year in which we were a PFIC, will be treated as ordinary income, and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• the amount allocated to each other year will be subject to tax at the highest tax rate in effect for that year for individuals or corporations, as applicable, and the interest charge generally applicable to underpayments of tax will be imposed on the resulting tax attributable to each such year.

Although the determination of whether we are a PFIC is made annually, if we are a PFIC for any taxable year in which you hold our Class A Ordinary Shares, you will generally be subject to the special tax rules described above for that year and for each subsequent year in which you hold the Class A Ordinary Shares (even if we do not qualify as a PFIC in such subsequent years). However, if we cease to be a PFIC, you can avoid the continuing impact of the PFIC rules by making a special election to recognize gain as if your Class A Ordinary Shares had been sold on the last day of the last taxable year during which we were a PFIC. You are urged to consult your own tax advisor about this election.

In lieu of being subject to the special tax rules discussed above, if we are a PFIC for any taxable year in which you hold our Class A Ordinary Shares, you may make a mark-to-market election with respect to your Class A Ordinary Shares provided such Class A Ordinary Shares are treated as "marketable stock." The Class A Ordinary Shares generally will be treated as marketable stock if they are regularly traded on a "qualified exchange or other market" (within the meaning of the applicable Treasury regulations). A class of stock is considered "regularly traded" on a qualified exchange or other market for any calendar year during which such class of stock is traded, other than in de minimis quantities, on at least 15 days during each calendar quarter. The Class A Ordinary Shares are listed on the NYSE American, which is treated as a qualified exchange for these purposes, but no assurance can be given that the Class A Ordinary Shares will be "regularly traded" for purposes of the mark-to-market election.

If you make an effective mark-to-market election, for each taxable year that we are a PFIC you will include as ordinary income the excess of the fair market value of your Class A Ordinary Shares at the end of the year over your adjusted tax basis in the Class A Ordinary Shares. You will be entitled to deduct as an ordinary loss in each such year the excess of your adjusted tax basis in the Class A Ordinary Shares over their fair market value at the end of the year, but only to the extent of the net amount previously included in income as a result of the mark-to-market election. Your adjusted tax basis in the Class A Ordinary Shares will be increased by the amount of any income inclusion and decreased by the amount of any deductions under the mark-to-market rules. In addition, upon the sale or other disposition of your Class A Ordinary Shares in a year that we are a PFIC, any gain will be treated as ordinary income and any loss will be treated as ordinary loss to the extent of the net amount of previously included income as a result of the mark-to-market election, and thereafter as capital loss.

If you make a mark-to-market election, it will be effective for the taxable year for which the election is made and all subsequent taxable years unless the Class A Ordinary Shares are no longer regularly traded on a qualified exchange or other market, or the Internal Revenue Service, or the IRS, consents to the revocation of the election. However, because a mark-to-market election cannot be made for any lower-tier PFICs that we may own (as discussed below), you will generally continue to be subject to the special tax rules discussed above with respect to your indirect interest in any such lower-tier PFIC. You are urged to consult your tax advisor about the availability of the mark-to-market election, and whether making the election would be advisable in your particular circumstances.

------

[T](#ib885b07745664dce8cc23d0d35721f6b_7)[able](#ib885b07745664dce8cc23d0d35721f6b_7)[of](#ib885b07745664dce8cc23d0d35721f6b_7)[Contents](#ib885b07745664dce8cc23d0d35721f6b_7)

Alternatively, you can sometimes avoid the special tax rules described above by electing to treat a PFIC as a "qualified electing fund" under Section 1295 of the Code. However, this option is not available to you with respect to our Class A Ordinary Shares because we do not intend to comply with the requirements necessary to permit you to make this election.

If we are a PFIC for any taxable year during which you hold our Class A Ordinary Shares (possibly including, for these purposes, taxable years in which you held HPX Class A Ordinary Shares (if applicable)) and any of our non-U.S. subsidiaries is also a PFIC, you will be treated as owning a proportionate amount (by value) of the shares of the lower-tier PFIC for purposes of the application of the PFIC rules. You are urged to consult your tax advisors about the application of the PFIC rules to any of our subsidiaries.

You will generally be required to file IRS Form 8621 if you hold our Class A Ordinary Shares in any year in which we are classified as a PFIC. You are urged to consult your tax advisors concerning the U.S. federal income tax consequences of holding Class A Ordinary Shares if we are considered a PFIC in any taxable year.

***Information Reporting and Backup Withholding***

In general, information reporting will apply to dividends in respect of our Class A Ordinary Shares and the proceeds from the sale, exchange or other disposition of Class A Ordinary Shares that are paid to you within the United States (and in certain cases, outside the United States), unless you are an exempt recipient. Backup withholding may apply to such payments if you fail to provide a taxpayer identification number and a certification that you are not subject to backup withholding or if you fail to report in full dividend and interest income.

Backup withholding is not an additional tax. Any amounts withheld under the backup withholding rules will be allowed as a refund or a credit against your U.S. federal income tax liability provided the required information is timely furnished to the IRS.

Certain U.S. Holders are required to report information relating to our Class A Ordinary Shares, subject to certain exceptions (including an exception for Class A Ordinary Shares held in accounts maintained by certain financial institutions), by attaching a complete IRS Form 8938, Statement of Specified Foreign Financial Assets, with their tax return for each year in which they hold the Class A Ordinary Shares. You are urged to consult your own tax advisors regarding information reporting requirements relating to your ownership of the Class A Ordinary Shares.

As a foreign private issuer, we are exempt from certain rules under the Exchange Act, including the proxy rules, which impose certain disclosure and procedural requirements for proxy solicitations for U.S. and other issuers(including the requirement applicable to emerging growth companies to disclose the compensation of its Chief Executive Officer and the other two most highly compensated executive officers on an individual, rather than an aggregate, basis). Moreover, we have four months after the end of each fiscal year to file our annual report with the SEC, are not required to file certain periodic reports at all, and are not required to file other periodic reports and financial statements with the SEC as frequently or within the same time frames as U.S. issuers with securities registered under the Exchange Act.However, we issue, and expect to continue issuing, interim quarterly financial information publicly and furnish it to the SEC under cover of Form 6-K.We are not required to comply with Regulation FD, which imposes restrictions on the selective disclosure of material information to shareholders. In addition, our officers, directors and principal shareholders are exempt from the reporting and short-swing profit recovery provisions of Section 16 of the Exchange Act and the rules under the Exchange Act with respect to their purchases and sales of our Securities.

Interest rate risk arises from the portion of our debt pegged to the long-term interest rate — CDI and interest earning bank deposits at the CDI rate, 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 us to cash flow interest rate risk.

Loans issued at fixed rates expose us to fair value risk associated with interest rate. Considering that a substantial part of our loans is linked to fixed rates, our management believes that the risk of material changes in income and cash flows is low.

We set forth below three scenarios (probable, possible and remote) for simulation. In the probable scenario, the rates disclosed by the BM&F (*Bolsa de Mercadorias e Futuros*) were set forth by our management and the possible and remote scenario, a 25% and 50% deterioration on interest rates, respectively, in the variables. These amounts have been calculated using the amounts presented in the notes to the audited Consolidated Financial Statements for cash and cash equivalents and loans and financing:

Due to the nature, complexity, and isolation of a single variable, the estimates presented above may not faithfully represent the value of the loss, if the variable in question has the deterioration shown.

***Credit risk***

Credit risk is the risk of our financial loss if a customer or counterparty to a financial instrument fails to meet its contractual obligations and arises mainly from our receivables from customers and investments in debt securities. Credit risk also arises from cash and cash equivalents, deposits in banks and other financial institutions, and exposure to client credit. For banks and financial institutions, we only purchase securities of issuers with a prime rating.

When analyzing credit risk, our management evaluates the client's creditworthiness by taking into account their financial position, past experience and other factors. Individual risk limits are determined with basis on internal or external classifications in accordance with limits determined by our management. The use of credit limits is regularly monitored. See notes 3.22.1 and 5 to our audited Consolidated Financial Statements for additional information.

***Liquidity risk***

Liquidity risk is the risk associated with the difficulty in meeting the obligations associated with our financial liabilities that are settled by delivering cash or another financial assets. Our objective when managing liquidity is to ensure, to the extent possible, that we will have sufficient liquidity to meet our liabilities when they are due, under both normal and stressed conditions, without incurring in unacceptable losses or risking damage to our reputation and our business.

The cash flow forecast is carried out by our management. Our management monitors the continuous forecasts of our liquidity requirements to ensure we have enough cash to satisfy operating needs. This forecast takes into consideration our debt financing plans, compliance with financial covenants, expected earnings and cash flows and, if applicable, external or legal regulatory requirements — for example, currency restrictions.

We hold surplus cash in excess of amounts we need for working capital, 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 December 31, 2024, we maintained short-term funds of R$222.1 million, compared to R$143.5 million as of December 31, 2023.

**Item 15. CONTROLS AND PROCEDURES**

**A.Disclosure Controls and Procedures**

We have evaluated, with the participation of our Chief Executive Officer and Chief Financial Officer, the effectiveness of our disclosure controls and procedures as of December 31, 2024. "Disclosure controls and procedures" as defined in Rules 13a-15(e) and 15d-15(e) under the Exchange Act means controls and procedures of a company that are designed to ensure that information required to be disclosed by a company in the reports that it files or submits under the Exchange Act is recorded, processed, summarized and reported, within the time periods specified in the applicable rules and forms. Disclosure controls and procedures include, without limitations, controls and procedures designed to ensure that information required to be disclosed by a company in the reports that it files or submits under the Exchange Act is accumulated and communicated to its management, including its principal executive and principal financial officers, as appropriate to allow timely decisions regarding required disclosure. There are inherent limitations to the effectiveness of any system of disclosure controls and procedures, including the possibility of human error and the circumvention or overriding of the controls and procedures. Accordingly, even effective disclosure controls and procedures can only provide reasonable assurance of achieving their control objectives.

Based upon the evaluation of our disclosure controls and procedures as of December 31, 2024, our Chief Executive Officer and Chief Financial Officer concluded that our disclosure controls and procedures were not effective due to the material weaknesses in internal control over financial reporting described below under "B. Management's Annual Report on Internal Control Over Financial Reporting."

**B.Management's Annual Report on Internal Control Over Financial Reporting**

Our management is responsible for establishing and maintaining adequate internal control over financial reporting as defined in Rules 13a-15(f) under the Exchange Act. Our internal control over financial reporting is designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with IFRS and includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the Company; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with IFRS, and that receipts and expenditures of the Company are being made only in accordance with authorizations of management and directors of the Company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use or disposition of the Company's assets that could have a material effect on the financial statements. Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements.

Management has assessed the effectiveness of the Company's internal control over financial reporting as of December 31, 2024, utilizing the criteria in the Committee of Sponsoring Organizations of the Treadway Commission's Internal Control-Integrated Framework (2013). Based on its assessment, our management determined that, as of December 31, 2024, the Company's internal control over financial reporting was not effective due to material weaknesses described below. A material weakness is a deficiency, or combination of deficiencies, in internal control over financial reporting such that there is a reasonable possibility that a material misstatement of a company's annual or interim financial statements will not be prevented or detected on a timely basis.

The material weaknesses related 2024 Financial Statements which include certain material weaknesses previously identified and disclosed in our annual report for the fiscal year ended December 31, 2022, and the report for the fiscal year ended December 31, 2023:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• lack of effective controls over the completeness, existence and accuracy of the inputs to calculate and record the cost of sales;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• lack of effective controls over the financial reporting process with sufficient precision to prevent or detect misstatements in a timely manner;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• lack of effective controls over the application of revenue recognition accounting standards, affecting revenue, cost of sales, account receivable, and unbilled process, with sufficient precision to prevent or detect misstatements in a timely manner;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• lack of effective controls over the accuracy of the discount rate used to calculate lease-related accounts.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• lack of a sufficient number of personnel in the acquired entities with an adequate level of knowledge and experience in the closing functions of our financial reports and related disclosures, to process the transition to the application of IFRS, consistent with our financial reporting requirements;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• design and operation of our accounting and financial reporting closing functions, where the required policies and procedures were not implemented or operating effectively at period end, resulting in a number of adjustments to our audited consolidated financial statements during the course of the audit;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• inadequate segregation of duties and/or lack of a policy for delegation of authorities;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• deficiencies in our internal control oversight framework, including the absence of an internal audit function and poor internal communication and documentation related to risk management and internal controls; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• deficiencies in information technology controls, such as information classification, vulnerability management, encryption, and business continuity management, and lack of automation in financial reporting consolidation, which enables certain off-book adjustments.

The Company and its Board are committed to maintaining an effective internal control environment. The Company's management, with the oversight of the Board, has evaluated the material weaknesses described above and designed a remediation plan to address the material weaknesses. The remediation of previously and currently identified material weaknesses and strengthening our internal control environment required a substantial effort throughout 2024, and will continue to require a substantial effort in 2025.

The material weaknesses cannot be considered completely remediated until the applicable controls have operated for a sufficient period of time and management has concluded, through testing, that these controls are operating effectively. The Company also cannot assure you that our efforts will be effective or sufficient to prevent any future material weakness in our internal control over financial reporting.

The remediation plan for 2025 includes the following ongoing actions:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• approval and implementation of the draft of the delegation of authority policy, which is designed to ensure clear segregation of duties;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• completion of the integration processes for acquired companies in North America;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• enhancement of the utilization of SAP Enterprise Resource Software or similar system across Ambipar Response companies in Brazil and North America;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• creation of detailed job descriptions for all areas within the Company, highlighting responsibilities related to internal controls and hiring of additional finance and accounting personnel with the requisite experience and knowledge, including a Chief Accounting Officer (CAO);

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• launch of an internal audit function, with a reporting line to the Board, to assess and improve internal controls regularly;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• review and adjustment of off-book practices in financial consolidation to ensure transparency and accuracy;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• standardization of internal procedures for the Board and applicable committees, including the audit committee, to increase the frequency and efficiency of meetings; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Implement an ETL (Extract, Transform, Load) technology to automate key financial and accounting processes, streamlining data flow and improving the timeliness of financial reporting.

The following details the key items of the remediation plan that have been completed to date:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• establishment of ongoing monitoring mechanisms for internal control procedures;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• hiring of a SOX compliance consulting firm (Ambipar ESG);

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• development of an outsourced risk management and internal controls division to refine existing risk assessments;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• organization of a comprehensive communication and training plan focusing on ethics, internal controls, and compliance frameworks such as COSO and ISO;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• implementation of a whistleblowing policy, including an independent reporting hotlines; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• enhancement of ABAC (Anti-Bribery and Anti-Corruption) and AML/CFT (Anti-Money Laundering/Countering the Financing of Terrorism) compliance procedures.

***Development of an Outsourced Risk Management and Internal Controls Division to Refine Existing Risk Assessments***

In 2024, Ambipar Group established and implemented the Risk Management and Internal Controls Division ("GRC"), outsourcing this function to Ambipar ESG. The division is responsible for identifying, assessing, monitoring, and mitigating corporate risks that may impact Ambipar Group's strategic objectives. This division operates across all Ambipar's business units, including the Company, where it works to integrate risk management into operations.

Among its key responsibilities are mapping risks across various categories (strategic, financial, climate-related, compliance/regulatory, reputational, among others), assessing impact and likelihood using tools such as the risk matrix (heatmap), and prioritizing corrective actions. The division is also responsible for advising various departments on the implementation of effective internal controls, continuous monitoring, and risk communication.

Throughout 2024, several initiatives were implemented to enhance the Company's risk management and internal controls. As part of this effort, interviews were conducted with professionals and managers across various departments and subsidiaries to map and analyze processes, risks, and internal controls in detail. This process included the description of activities, identification of associated risks, evaluation of existing control effectiveness, and identification of improvement opportunities. Based on the collected information, a comprehensive database was structured to document existing processes, risks, and controls, as well as to define process and risk owners.

To further strengthen risk management, the Company developed its risk assessment procedures using the SAI360 platform, which has been internally adapted within the Ambipar Group as "a360". This platform was employed to conduct comprehensive inherent risk assessments, categorizing impact and likelihood, as well as residual risk assessments based on implemented controls. The impact assessments considered financial, brand reputation, social and environmental, climate-related, ethical-compliance, personnel (safety), and operational factors. Risks were classified into impact levels - low, moderate, high, and very high - and probability levels - rare, unlikely, possible and likely. The results are visualized by the CEO and CFO in a risk matrix, allowing for the identification and prioritization of key risks requiring mitigation. Additionally, a360 enables the creation of a database of process owners, improving the traceability of internal procedures and controls within the company's structure.

As part of the ongoing efforts to refine risk management, control and residual risk assessments were conducted for the identified corporate risks. A360 was utilized to evaluate the effectiveness of existing controls, assess residual risks, and prioritize mitigation actions. The assessment results are organized to support continuous monitoring and risk management by the CEO. Moreover, a360 allows for direct reporting of incidents within the Company and Ambipar Group, automatically forwarding them to responsible teams and facilitating the development of appropriate treatment plans.

To support and enhance the activities of the GRC division, in October 2024, Ambipar Group approved an updated Risk Management Policy, which establishes guidelines and responsibilities for managing risks across the Company. The risk management framework consists of several stages, including risk identification and assessment, classification by impact and probability, risk prioritization and mitigation (elimination, reduction, transfer, or acceptance), monitoring, communication, and stakeholder consultation. The Board, audit committee, and executive management play critical roles in this process.

***Internal Audit Structure***

The Company has taken steps towards the implementation of the internal audit function, including the drafting of an internal audit policy, which outlines, among other provisions, the responsibilities of the internal audit function and individual auditors; procedures for the selection and contracting of audit services (overseen by the Board, taking into consideration recommendations from the audit committee); and guidelines for the development of the audit plan. Additionally, a draft internal audit plan for 2025 has been prepared, outlining specific objectives by area/business unit, an audit timeline, and the planning matrix for conducting audits. This plan is pending final approval. Further structuring and development of the internal audit function are planned for 2025 to ensure full alignment with the Risk Management Policy and enhance its effectiveness.

The Risk Management Policy establishes that the internal audit function is responsible for evaluating the Company's risk environment, identifying and addressing potential failures, fostering a risk management culture, assessing the quality and effectiveness of risk management, control, and governance processes, and reporting its findings to the audit committee. As of the date of this annual report, the internal audit function has not yet been fully structured, but it is expected to be operational during 2025. The internal audit function will report directly to the Board while maintaining oversight obligations to the audit committee, in line with best market practices to ensure its independence and autonomy.

***Organization of a Comprehensive Communication and Training Plan on Ethics, Internal Controls, and Compliance Frameworks such as COSO and ISO***

Between September and November 2024, we conducted a series of training sessions on Internal Controls, ISO standards, COSO, and SOx regulation for the Company employees. These live online training sessions were delivered in three languages—Portuguese, Spanish, and English—covering employees across Latin America, Brazil, Chile, the United States, Canada, the United Kingdom, Ireland, and other regions.

In addition to the training sessions, we provided a handbook (available in English, Portuguese, and Spanish) to employees on the topics of internal controls, COSO, and SOx. This material includes supplementary information, frequently asked questions, as well as case studies on these topics.

***Assessment of Positions, Competencies, and Organizational Fit, with the Chief Accounting Officer (CAO) Position***

The Company is strengthening its corporate governance structure and compliance with the SOx by creating a position of Chief Accounting Officer (CAO). In the proposed organizational structure, the CAO will report directly to the CFO. Reporting to the CAO will be the business unit controllers, including those responsible for the U.S., Canada, Latin America, the United Kingdom, Ireland, and Brazil.

The CAO will reinforce internal controls over the company's accounting functions, with oversight and coordination responsibilities for the accounting team's activities. Alongside the CAO, the Company will also implement an internal accounting sub-certification process, led by the CAO. This sub-certification will encompass key controls and processes relevant to SOx compliance. The CAO will be responsible for consolidating, reviewing, and issuing a formal sub-certification, attesting to the quality, consistency, and compliance of financial information with applicable legislation before this information is presented to the CFO and CEO for final certification.

Within the accounting cycle, the CAO will be responsible for overseeing tax compliance, keeping the company in compliance with federal, state, local, and corporate tax laws and policies. Furthermore, the CAO will be responsible for analyzing financial reports, preparing periodic reports, summarized financial statements, and documents for annual review. The proper preparation of financial statements, reports analyzing the company's financial position, and management of accounting procedures, including the monthly close, will also fall under their responsibility.

As a foreign private issuer, we are permitted to follow home country practice in lieu of certain corporate NYSE governance rules, subject to certain requirements. We currently rely, and will continue to rely, on the foreign private issuer exemption with respect to the following rules:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Section 803 of the NYSE American LLC Company Guide, which requires that independent directors comprise a majority of a company's board of directors. As allowed by the laws of the Cayman Islands, independent directors do not comprise a majority of our Board.

**Item 16 K.CYBERSECURITY**

*Risk management and strategy*

We recognize the need to manage cybersecurity risk and seek to embed data protection and cybersecurity risk management in our operations. We are in the process of establishing processes for assessing, identifying, and managing material risks from potential unauthorized occurrences on or through our electronic information systems that could adversely affect the confidentiality, integrity, or availability of our information systems or the information residing on those systems. These processes for assessing, identifying, and managing material risks from cybersecurity threats have been integrated into our overall risk management system and processes.

As a foundation of our approach, we are implementing a data privacy and cybersecurity governance structure to help assess, identify and manage data privacy and cybersecurity risks. Our privacy and cybersecurity policies encompass incident response procedures, information security and vendor management. In order to help develop these policies and procedures, we monitor the privacy, data protection, artificial intelligence and cybersecurity laws, regulations and guidance applicable to us in the regions where we do business (including LGPD, GDPR, CCPA, CPRA, and the EU AI Act) as further described in "*Item 3.D. Key Information—Risk Factors*" and "*Item 4.B. Information on the Company—Business Overview— Regulatory Overview,*" as well as proposed privacy, data protection, artificial intelligence and cybersecurity laws, regulations, guidance and emerging risks.

As described in "*Item 3.D. Key Information—Risk Factors,*" our operations rely on the secure processing, storage and transmission of confidential and other information in our computer systems and networks. Computer viruses, hackers, employee or vendor misconduct, and other external hazards could expose our information systems and those of our vendors to security breaches, privacy and cybersecurity incidents or other disruptions, any of which could materially and adversely affect our business the Company faces regular privacy and cybersecurity risks which may cause regular adverse operational effects. The Company had no material privacy or cybersecurity incident during the 2024 fiscal year.

The sophistication of cybersecurity threats, including through the use of artificial intelligence, continues to increase, and the controls and preventative actions we take to reduce the risk of cybersecurity incidents and protect our systems, including testing our cybersecurity incident response plan, may be insufficient. In addition, new technology that could result in greater operational efficiency may further expose our computer systems to the risk of privacy or cybersecurity incidents.

*Governance*

As part of our overall risk management approach, we prioritize the identification and management of privacy and cybersecurity risk at several levels, including Board oversight, executive commitment and employee training. Our audit committee oversees the Board's responsibilities relating to operational risks, including privacy, cybersecurity, information technology, business continuity and data security risks of the Company. Our audit committee is informed of such risks through quarterly reports from our Chief Information Officer (CIO).

In 2025, the Company plans to create a privacy and cybersecurity committee composed of members of management to support processes related to assessing privacy and cybersecurity risk, and possibly also to provide summary reports on its activities, which the CIO would communicate as appropriate to the audit committee.

At the employee level, we maintain an experienced information technology team tasked with implementing our privacy and cybersecurity program and support the CIO in carrying out reporting, security and mitigation functions. We also hold employee onboarding trainings on privacy and cybersecurity, as well as records and information management, conduct phishing tests and generally seek to promote awareness of privacy and cybersecurity risk through communication and education of our employee population.

**REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM**

Shareholders and Board of Directors

**Ambipar Emergency Response**

São Paulo – SP

**Opinion on the consolidated financial statements**

We have audited the accompanying consolidated statements of financial position of **Ambipar Emergency Response and its subsidiaries (the "Company")**, as of December 31, 2024 and 2023, the related consolidated statements of income and statements of comprehensive income, changes in shareholders' equity, and cash flows for each of the three years in the period ended December 31, 2024 and the related notes (collectively referred to as the "consolidated financial statements"). In our opinion, the consolidated financial statements present fairly, in all material respects, the financial position of the Company as at December 31, 2024 and 2023, and the results of its operations and its cash flows for each of the three years in the period ended December 31, 2024, in conformity with IFRS Accounting Standards as issued by International Accounting Standards Board (IFRS Accounting Standards).

**Basis for opinion on the consolidated financial statements**

These consolidated financial statements are the responsibility of the Company's management. Our responsibility is to express an opinion on the Company's consolidated financial statements based on our audits. We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) ("PCAOB") and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the consolidated financial statements are free of material misstatement, whether due to error or fraud. The Company is not required to have, nor were we engaged to perform, an audit of its internal control over financial reporting. As part of our audits, we are required to obtain an understanding of internal control over financial reporting but not for the purpose of expressing an opinion on the effectiveness of the Company's internal control over financial reporting. Accordingly, we express no such opinion.

Our audits included performing procedures to assess the risks of material misstatement of the consolidated financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the consolidated financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the consolidated financial statements. We believe that our audits provide a reasonable basis for our opinion.

We have served as the Company's auditor since 2020.

São Paulo/SP - Brazil, June 23, 2025.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**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 1.1) 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 Consolidated Financial Statements from the dates that it obtained control of the Group Response.

| **Notes to the Consolidated Financial Statements**<br>**As of December 31, 2024, 2023 and 2022** <br>(Values expressed in thousands of Brazilian Reais, unless otherwise indicated) |

---

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

The Consolidated 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 Consolidated 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 Consolidated Financial Statements is being evidenced and corresponds to the one used by Management in the administration.

The Consolidated 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 Consolidated Financial Statements are not generated as a single legal entity. These Consolidated 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 Consolidated Financial Statements have been prepared on a going concern basis, which assumes that the Ambipar Emergency Response will be able to discharge its liabilities.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**2.2.Basis of consolidation**

These Consolidated 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.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**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.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**a)&nbsp;&nbsp;&nbsp;&nbsp;Amendments to IAS 1 Presentation of financial projections**

The IASB issued amendments to IAS 1 in January 2020 and October 2022, and these amendments clarified the following points:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• An entity's right to defer settlement of a liability for at least twelve months after the reporting period must be substantial and exist before the end of that period;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• If an entity's right to defer settlement of a liability is subject to covenants, such covenants have the existence of that right at the end of the reporting period only if the obligation to comply with the covenant exists at or before the end of the reporting period;

---

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• The classification of a liability as current or non-current is not affected by the likelihood that an entity will exercise its right to defer settlement; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• In the case of a liability that can be settled, at the option of the counterparty, by the transfer of the entity's own equity instruments, such settlement terms do not affect the classification of the liability as current or non-current only if the option of replacement as an equity instrument is exercised.

These amendments have no effect on the measurement of any items in the Group's consolidated financial statements. However, the classification of certain borrowings has changed from non-current to current as a result of the application of the amendments for the current year as well as for the comparative period.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**b)&nbsp;&nbsp;&nbsp;&nbsp;Amendments to IFRS 16 Leases**

We have increased the subsequent measurement requirements for sale and leaseback transactions, which meet the requirements of IFRS 15 for accounting purposes as a sale.

On September 22, 2022, the IASB issued amendments to IFRS 16 – which address the subsequent measurement for sale and leaseback (releaseback) transactions.

Prior to the amendments, IFRS 16 did not contain specific measurement requirements for lease liabilities that may contain payments of lease variables arising from a sale and leaseback transaction. When applying the subsequent measurement requirements for lease liabilities to a sale and leaseback transaction, the lessee-seller shall determine "lease payments" or "revised lease payments" in such a way that the lessee-seller does not recognise any amount of gain or loss relating to the right of use retained by the lessee-seller.

These amendments had no effect on the Group's consolidated financial projections.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**c)&nbsp;&nbsp;&nbsp;&nbsp;Amendments to IAS 7 and IFRS 7**

On 25 May 2023, the IASB issued amendments to IAS 7 Statement of Cash Flows and IFRS 7 Financial Instruments: Disclosures.

The amendments exclude entities from providing certain specific disclosures (qualitative and quantitative) relating to supplier financing arrangements (reverse factoring, forfeit or drawee risk). The amendments also provide guidance on the characteristics of supplier financing arrangements.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**2.4.New standards, revisions and interpretations issued that were not yet in force as of December 31, 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:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;a)&nbsp;&nbsp;&nbsp;&nbsp;**Amendments to IAS 21 -** disabling the disclosure of information that allowed users of projections to examine the impact of a currency not being exchangeable - effective for periods beginning on or after January 1, 2025;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;b)&nbsp;&nbsp;&nbsp;&nbsp;**Amendments to IFRS 7 and IFRS 9 -** classification and measurement of financial instruments and contracts that reference nature-dependent electricity - effective for periods beginning on or after January 1, 2026;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;c)&nbsp;&nbsp;&nbsp;&nbsp;**IFRS 18 Presentation and Disclosure in Financial Statements.** The new standard, which was issued by the IASB in April 2024, replaces IAS 1 and will result in major changes to IFRS Accounting Standards, including IAS 8 Basis of Preparation of Financial Statements (renamed from Accounting Policies, Changes in Accounting Estimates and Errors). Although IFRS 18 will not have any effect on the recognition and measurement of items in consolidated financial statements, it is expected to have a significant effect on the presentation and disclosure of certain items. These changes include categorization and subtotals in the income statement, aggregation/disaggregation and labeling of information, and disclosure of performance measures defined by management. A related standard has not yet been issued in Brazil - effective for periods beginning on or after January 1, 2027;

The Company is currently evaluating the impact of these new accounting standards and amendments. For the amendments to IFRS 19, the Company does not expect to be eligible to apply the reduced disclosure requirements.

**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**

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**3.1.Currency translation**

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**(a)&nbsp;&nbsp;&nbsp;&nbsp;Functional and presentation currency**

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

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**(b)&nbsp;&nbsp;&nbsp;&nbsp;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.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**(c)&nbsp;&nbsp;&nbsp;&nbsp;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.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**3.2.Use of accounting estimates and judgment**

The preparation of the Consolidated Financial Statements in accordance with IFRS Accounting Standards as issued by International Accounting Standards Board (IFRS Accounting Standards) 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.

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 Consolidated 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.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**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.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**3.4.Financial instruments**

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**3.4.1&nbsp;&nbsp;&nbsp;&nbsp;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:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• 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;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• How the performance of the portfolio is evaluated and reported to the Ambipar Emergency Response's management;

---

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• 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;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• 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

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• 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:

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

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• terms that may adjust the contractual coupon rate, including variable-rate features;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• prepayment and extension feature; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• 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 Consolidated 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.

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.

---

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**a)&nbsp;&nbsp;&nbsp;&nbsp;Recognition**

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

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Financial assets measured at amortized cost;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Debt investments measured at FVOCI; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• 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:

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

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• 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:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• 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

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• 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.

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.

---

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**b)&nbsp;&nbsp;&nbsp;&nbsp;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.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**c)&nbsp;&nbsp;&nbsp;&nbsp;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:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• significant financial difficulty of the debtor;

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

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

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

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

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**d)&nbsp;&nbsp;&nbsp;&nbsp;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.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**e)&nbsp;&nbsp;&nbsp;&nbsp;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 Company 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.

**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.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**3.4.2&nbsp;&nbsp;&nbsp;&nbsp;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:

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

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• 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.

**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 years. The balance on December 31, 2024 is R$35,448.

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.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**3.5.Intangible assets and Goodwill**

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;***(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:

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

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

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• It can be demonstrated how the software will generate probable future economic benefits;

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

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• 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.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;***(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.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;***(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.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;***(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.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;***(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.

In December 31, 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.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**3.6.Impairment of non-financial assets**

An impairment loss is recognized in the Consolidated 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.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**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.

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.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**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.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**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.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**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.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**3.10.1&nbsp;&nbsp;&nbsp;&nbsp;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.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**3.10.2&nbsp;&nbsp;&nbsp;&nbsp;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:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• 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;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• 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; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• 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.

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.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**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.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**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.

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:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• fixed payments, including in-substance fixed payments;

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

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

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• 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 1<sup>st</sup>, 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.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**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 Consolidated 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.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**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.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**3.15.Non-controlling interests**

The interest attributable to non-controlling shareholders was calculated based on the percentage mentioned in the table below, of total shareholders' equity in 2024.

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

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**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.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**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.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**3.19.Transactions eliminated on consolidation**

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.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**3.20.Financial income and financial expenses**

The Company's financial income and financial expenses include:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• interest income.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• interest expense.

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

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• 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:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• the gross carrying amount of the financial asset; or

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• the amortized cost of the financial liability.

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.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**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.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**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, 2024, 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.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**3.22.1.&nbsp;&nbsp;&nbsp;&nbsp;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.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**(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.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**(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.

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.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**(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.

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 December 31, 2024 and December 31, 2023.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**(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 December 31, 2024, the Company maintained short-term funds of R$222,062 (R$143,473 as of December 31, 2023) which are expected to readily generate cash inflows to manage the liquidity risk.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**(e)Foreign currency risks**

On December 31, 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 year ended.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**3.22.2&nbsp;&nbsp;&nbsp;&nbsp;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 level of indebtedness.

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-gap measure.

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 December 31, 2024 and December 31, 2023, can be summarized as follows:

---

| | | |
|:---|:---|:---|
| **Consolidated financial information** | **December 31, 2024** | **December 31, 2023** |
| Loans and financing and debentures | 1454039 | 1247652 |
| Less: cash and cash equivalents | (358434) | (423266) |
| Net bank loans and financing | **1095605** | **824386** |
| Total shareholders' equity | 1816497 | 1356797 |
| Total capital | **2912102** | **2181183** |
| **Leverage ratio** | **37.6%** | **37.8%** |

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**3.22.3.&nbsp;&nbsp;&nbsp;&nbsp;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:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**▪ Level 1:** prices charged (unadjusted) in active markets for identical assets or liabilities;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**▪ 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

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**▪ Level 3:** inputs for the asset or liability that are not based on observable market variables (non-observable inputs).

Financial investments are mainly represented by Bank Deposit Certificates and Capitalization Bonds from first-rate financial institutions, with low credit risk, whose profitability is linked to the variation of the Interbank Deposit Certificate (CDI) and offers immediate liquidity and maturity in up to 90 days, indexed to 104% of the CDI for December 31, 2024, and the year ended December 31, 2023.

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 December 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.

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 1<sup>st</sup>, 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.

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

**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.

**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** | |
| 2025 | 95,413 |
| 2026 | 10,762 |

| Current | 95,413 |
| Non-current | 13,762 |

**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. Goodwill arising from a business combination is allocated to a CGU or group of CGUs (Cash Generating Unit), each CGU or group of CGUs being the lowest level at which goodwill is monitored for internal management purposes and not being larger than an operating segment. Goodwill related to operations in Brazil, Latin America (Other than Brazil), North America and Europe is allocated to each operating segment (see note 18).

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

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 December 31, 2024, and December 31<sup>st</sup>, 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$3,222,425 (R$2,683,399 as of December 31, 2023). Management foresees that the two hypotheses of alteration are reasonably possible.

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 2024 and the long-term projections of its subsidiaries. Estimated future cash flows were discounted at the rate equivalent to the 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 | 11.8 |
| Terminal value growth rate | 3.8 |

---

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:

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

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;▪ 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

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

For December 31, 2024, and the year ended December 31, 2023, the estimated value in use exceeded the carrying amount.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**(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.

Company Management believes that resolving these issues will not have an effect significantly different from the provisioned amount.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**15.2.&nbsp;&nbsp;&nbsp;&nbsp;Rollforward of provision for contingencies**

Changes in provision for contingencies As of December 31, 2024, and December 31, 2023, are as follows:

Civil claims refer to lawsuits filed by former suppliers and partners related to compensation for property damages arising from the commercial relationship that existed with the Group Reponse companies.

The Company has labor contingencies classified as a possible loss As of December 31, 2024, in the amount estimated by its legal advisors of R$1,256 (as of December 31, 2023, in the amount of R$982).

Notwithstanding the foregoing in this Section 4(c), it is intended that any action under the Plan intended to qualify for an exemption provided by Rule 16b-3 promulgated under the Exchange Act related to Persons who are subject to Section 16 of the Exchange Act will be taken only by the Board or by a committee or subcommittee of two or more Qualifying Directors. However, the fact that any member of such committee or subcommittee shall fail to qualify as a Qualifying Director shall not invalidate any action that is otherwise valid under the Plan.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(d)<u>Finali</u>ty <u>of Decisions</u>. Unless otherwise expressly provided in the Plan, all designations, determinations, interpretations, and other decisions under or with respect to the Plan, any Award or any Award Agreement shall be within the sole discretion of the Committee, may be made at any time, and shall be final, conclusive, and binding upon all Persons, including, without limitation, any member of the Company Group, any Participant, any holder or beneficiary of any Award, and any shareholder of the Company.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(e)<u>Indemnification</u>. No member of the Board, the Committee, or any employee or agent of any member of the Company Group (each such Person, an **<u>"Indemnifiable Person")</u>** shall be liable for any action taken or omitted to be taken or any determination made with respect to the Plan or any Award hereunder (unless constituting fraud, dishonesty, or a willful criminal act or omission). Each Indemnifiable Person shall be indemnified and held harmless by the Company to the maximum extent permitted by Applicable Law against and from any loss, cost, liability, or expense (including attorneys' fees) that may be imposed upon or incurred by such Tndemnifiable Person in connection with or resulting from any action, suit, or proceeding to which such Tndemnifiable Person may be a party or in which such Indemnifiable Person may be involved by reason of any action taken or omitted to be taken or determination made with respect to the Plan or any Award hereunder and against and from any and all amounts paid by such Jndemnifiable Person with the Company's approval, in settlement thereof, or paid by such Indemnifiable Person in satisfaction of any judgment in any such action, suit, or proceeding against such Indernnifiable Person, and the Company shall advance to such Indemnifiable Person any such expenses promptly upon written request (which request shall include an undertaking by the Indernnifiable Person to repay the amount of such advance if it shall ultimately be determined, as provided below, that the Indemnifiable Person is not entitled to be indemnified); *provided,* that the Company shall have the right, at its own expense, to assume and defend any such action, suit, or proceeding and once the Company gives notice of its intent to assume the defense, the Company shall have sole control over such defense with counsel of the Company's choice. The foregoing right of indemnification shall not be available to an Indernnifiable Person to the extent that a final judgment or other final adjudication (in either case not subject to further appeal) binding upon such Indemnifiable Person determines that the acts, omissions, or determinations of such Indemnifiable Person giving rise to the indemnification claim resulted from such Indemnifiable Person's fraud, dishonesty, or willful criminal act or omission or that such right of indemnification is otherwise prohibited by Applicable Law or by the organizational documents of any member of the Company Group. The foregoing right of indemnification shall not be exclusive of or otherwise supersede any other rights of indemnification to which such Tndemnifiable Persons may be entitled under (i) the organizational documents of any member of the Company Group, (ii) pursuant to Applicable Law,

&nbsp;&nbsp;&nbsp;&nbsp;(iii)an individual indemnification agreement or contract, or otherwise, or (iv) any other power that the Company may have to

indemnify such Tndemnifiable Persons or hold such Tndemnifiable Persons harmless.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(f)<u>Board Authorit</u>y. Notwithstanding anything to the contrary contained in the Plan, the Board may, in its sole discretion, at any time and from time to time, grant Awards and administer the Plan with respect to such Awards. Any such actions by the Board shall be subject to Applicable Law. In any such case, the Board shall have all the authority granted to the Committee under the Plan.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**5.Grant of Awards; Shares Subject to the Plan; Limitations.**

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(a)<u>Grants.</u> The Committee may, from time to time, grant Awards to one or more Eligible Persons. All Awards granted under the Plan shall vest and become exercisable in such manner and on such date or dates or upon such event or events as determined by the Committee, including, without limitation, attainment of Performance Conditions.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b)<u>Share Reserve and Limits</u>. Awards granted under the Plan shall be subject to the following limitations: (i) subject to Section 10 of the Plan, no more than 2,062,000 Class A Ordinary Shares (the **<u>"Absolute</u> <u>Share Limit")</u>** shall be available for Awards under the Plan; and (ii) subject to Section 10 of the Plan, no more than the number of Class A Ordinary Shares equal to the Absolute Share Limit may be issued in the aggregate pursuant to the exercise of Incentive Share Options granted under the Plan.

------

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(c)<u>Share Countin</u>g. Other than with respect to Substitute Awards, to the extent that an Award expires or is canceled, forfeited, terminated, settled in cash, or otherwise is settled without issuance to the Participant of the full number of Class A Ordinary Shares to which the Award related, the unissued Class A Ordinary Shares will again be available for grant under the Plan. Class A Ordinary Shares withheld in payment of the Exercise Price, or taxes relating to an Award, and shares equal to the number of shares surrendered in payment of any Exercise Price, or taxes relating to an Award, shall be deemed to constitute shares not issued to the Participant and shall be deemed to again be available for Awards under the Plan; *provided, however,* that such shares shall not become available for issuance hereunder if either: (i) the applicable shares are withheld or surrendered following the termination of the Plan; or

&nbsp;&nbsp;&nbsp;&nbsp;(ii) at the time the applicable shares are withheld or surrendered, it would constitute a material revision of the Plan subject to shareholder approval under any then-applicable rules of the national securities exchange on which the Class A Ordinary Shares are listed.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(d)<u>Source of Shares</u>. Class A Ordinary Shares issued by the Company in settlement of Awards may be authorized and unissued shares, Class A Ordinary Shares held in the treasury of the Company, Class A Ordinary Shares purchased on the open market or by private purchase, or a combination of the foregoing.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(e)<u>Substitute Awards</u>. Awards may, in the sole discretion of the Committee, be granted under the Plan in assumption of, or in substitution for, outstanding Awards previously granted by an entity directly or indirectly acquired by the Company or with which the Company combines **<u>("Substitute Awards").</u>** Substitute Awards shall not be counted against the Absolute Share Limit; *provided,* that Substitute Awards issued in connection with the assumption of, or in substitution for, outstanding Options intended to qualify as "incentive stock options" within the meaning of Section 422 of the Code shall be counted against the aggregate number of Class A Ordinary Shares available for Awards of Incentive Share Options under the Plan. Subject to applicable stock exchange requirements, available Class A Ordinary Shares under a shareholder-approved plan of an entity directly or indirectly acquired by the Company or with which the Company combines (as appropriately adjusted to reflect the acquisition or combination transaction) may be used for Awards under the Plan and shall not reduce the number of Class A Ordinary Shares available for issuance under the Plan.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**6.Options.**

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(a)<u>General.</u> Each Option granted under the Plan shall be evidenced by an Award Agreement, which agreement need not be the same for each Participant. Each Option so granted shall be subject to the conditions set forth in this Section 6, and to such other conditions not inconsistent with the Plan as may be reflected in the applicable Award Agreement. All Options granted under the Plan shall be Nonqualified Share Options unless the applicable Award Agreement expressly states that the Option is intended to be an Incentive Share Option. Incentive Share Options shall be granted only to Eligible Persons who are employees of a member of the Company Group, and no Incentive Share Option shall be granted to any Eligible Person who is ineligible to receive an Incentive Share Option under the Code. No Option shall be treated as an Incentive Share Option unless the Plan has been approved by the shareholders of the Company in a manner intended to comply with the shareholder approval requirements of Section 422(b)(l) of the Code; *provided,* that any Option intended to be an Incentive Share Option shall not fail to be effective solely on account of a failure to obtain such approval, but rather such Option shall be treated as a Nonqualified Share Option unless and until such approval is obtained. In the case of an Incentive Share Option, the terms and conditions of such grant shall be subject to, and comply with, such rules as may be prescribed by Section 422 of the Code. If for any reason an Option intended to be an Incentive Share Option (or any portion thereof) shall not qualify as an Incentive Share Option, then, to the extent of such nonqualification, such Option or portion thereof shall be regarded as a Nonqualified Share Option appropriately granted under the Plan.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b)<u>Exercise Price</u>. Except as otherwise provided by the Committee in the case of Substitute Awards, the exercise price **<u>("Exercise Price")</u>** per Common Share for each Option shall not be less than 100% of the Fair Market Value of such share (determined as of the Date of Grant); *provided, however,* that in the case of an Incentive Share Option granted to an employee who, at the time of the grant of such Option, owns shares representing more than 10% of the voting power of all classes of shares of any member of the Company Group, the Exercise Price per share shall be no less than 110% of the Fair Market Value per share on the Date of Grant.

------

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(c)<u>Vesting</u> <u>and Expiration; Termination</u>.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(i)Options shall vest and become exercisable in such manner and on such date or dates or upon such event or events as determined by the Committee including, without limitation, those set forth in Section 5(a) of the Plan; *provided, however,* that notwithstanding any such vesting dates or events, the Committee may in its sole discretion accelerate the vesting of any Options at any time and for any reason. Options shall expire upon a date determined by the Committee, not to exceed ten years from the Date of Grant (the **<u>".Qntion Period");</u>** *provided,* that if the Option Period (other than in the case of an Incentive Share Option) would expire at a time when trading in the Class A Ordinary Shares is prohibited by the Company's insider trading policy (or Company imposed "blackout period"), then the Option Period shall be automatically extended until the 30<sup>t</sup><sup>h</sup> day following the expiration of such prohibition. Notwithstanding the foregoing, in no event shall the Option Period exceed five years from the Date of Grant in the case of an Incentive Share Option granted to a Participant who on the Date of Grant owns shares representing more than 10% of the voting power of all classes of shares of any member of the Company Group.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(ii)Unless otherwise determined by the Committee, whether in an Award Agreement or otherwise, in the event of:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(A) a Participant's Termination by the Service Recipient for Cause, all outstanding Options granted to such Participant shall immediately terminate and expire; (B) a Participant's Termination due to death or Disability, each outstanding unvested Option granted to such Participant shall immediately terminate and expire, and each outstanding vested Option shall remain exercisable for one year thereafter (but in no event beyond the expiration of the Option Period); and (C) a Participant's Termination for any other reason, each outstanding unvested Option granted to such Participant shall immediately terminate and expire, and each outstanding vested Option shall remain exercisable for 90 days thereafter (but in no event beyond the expiration of the Option Period).

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(d)<u>Method of Exercise and Form of Payment</u>. No Class A Ordinary Shares shall be issued pursuant to any exercise of an Option until payment in full of the Exercise Price therefor is received by the Company and the Participant has paid to the Company an amount equal to any Federal, state, local, and non-U.S. income, employment, and any other applicable taxes that are statutorily required to be withheld in accordance with Section 12(d) of the Plan. Options which have become exercisable may be exercised by delivery of written or electronic notice of exercise to the Company (or telephonic instructions to the extent provided by the Committee) in accordance with the terms of the Option accompanied by payment of the Exercise Price. The Exercise Price shall be payable: (i) in cash, check, cash equivalent, and/or Class A Ordinary Shares valued at the Fair Market Value at the time the Option is exercised (including, pursuant to procedures approved by the Committee, by means of attestation of ownership of a sufficient number of Class A Ordinary Shares in lieu of actual issuance of such shares to the Company); *provided,* that such Class A Ordinary Shares are not subject to any pledge or other security interest and have been held by the Participant for at least six months (or such other period as established from time to time by the Committee in order to avoid adverse accounting treatment applying generally accepted accounting principles **<u>("GAAP"));</u>** or (ii) by such other method as the Committee may permit in its sole discretion, including, without limitation (A) in other property having a fair market value on the date of exercise equal to the Exercise Price; (B) if there is a public market for the Class A Ordinary Shares at such time, by means of a broker-assisted "cashless exercise" pursuant to which the Company is delivered (including telephonically to the extent permitted by the Committee) a copy of irrevocable instructions to a stockbroker to sell the Class A Ordinary Shares otherwise issuable upon the exercise of the Option and to deliver promptly to the Company an amount equal to the Exercise Price; or (C) a "net exercise" procedure effected by withholding the minimum number of Class A Ordinary Shares otherwise issuable in respect of an Option that are needed to pay the Exercise Price and any Federal, state, local, and non-U.S. income, employment, and any other applicable taxes that are statutorily required to be withheld in accordance with Section 12(d) of the Plan. Any fractional Class A Ordinary Shares shall be settled in cash.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(e)<u>Notification upon Disqualifying Disposition of an Incentive Share Option</u>. Each Participant awarded an Incentive Share Option under the Plan shall notify the Company in writing immediately after the date the Participant makes a disqualifying disposition of any Class A Ordinary Shares acquired pursuant to the exercise of such Incentive Share Option. A disqualifying disposition is any disposition (including, without limitation, any sale) of such Class A Ordinary Shares before the later of (i) the date that is two years after the Date of Grant of the Incentive Share Option, or (ii) the date that is one year after the date of exercise of the Incentive Share Option.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(f)<u>Compliance With Applicable Laws, etc</u>. Notwithstanding the foregoing, in no event shall a Participant be permitted to exercise an Option in a manner which the Committee determines would violate the Sarbanes-Oxley Act of 2002, as it may be amended from time to time, or any other Applicable Law.

------

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**7.Share Appreciation Rights.**

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(a)<u>General.</u> Each SAR granted under the Plan shall be evidenced by an Award Agreement. Each SAR so granted shall be subject to the conditions set forth in this Section 7, and to such other conditions not inconsistent with the Plan as may be reflected in the applicable Award Agreement. Any Option granted under the Plan may include tandem SARs. The Committee also may award SARs to Eligible Persons independent of any Option.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b)<u>Strike Price</u>. Except as otherwise provided by the Committee in the case of Substitute Awards, the strike price **<u>("Strike Price")</u>** per Common Share for each SAR shall not be less than 100% of the Fair Market Value of such share (determined as of the Date of Grant). Notwithstanding the foregoing, a SAR granted in tandem with (or in substitution for) an Option previously granted shall have a Strike Price equal to the Exercise Price of the corresponding Option.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(c)<u>Vesting and</u> <u>Expiration;</u> <u>Termination</u>.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(i)A SAR granted in connection with an Option shall become exercisable and shall expire according to the same vesting schedule and expiration provisions as the corresponding Option. A SAR granted independent of an Option shall vest and become exercisable in such manner and on such date or dates or upon such event or events as determined by the Committee including, without limitation, those set forth in Section 5(a) of the Plan; *provided, however,* that notwithstanding any such vesting dates or events, the Committee may, in its sole discretion, accelerate the vesting of any SAR at any time and for any reason. SARs shall expire upon a date determined by the Committee, not to exceed ten years from the Date of Grant (the **<u>"SAR Period");</u>** *provided,* that if the SAR Period would expire at a time when trading in the Class A Ordinary Shares is prohibited by the Company's insider trading policy (or Company-imposed "blackout period"), then the SAR Period shall be automatically extended until the 30th day following the expiration of such prohibition.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(ii)Unless otherwise determined by the Committee, whether in an Award Agreement or otherwise, in the event of:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(A) a Participant's Termination by the Service Recipient for Cause, all outstanding SARs granted to such Participant shall immediately terminate and expire; (B) a Participant's Termination due to death or Disability, each outstanding unvested SAR granted to such Participant shall immediately terminate and expire, and each outstanding vested SAR shall remain exercisable for one year thereafter (but in no event beyond the expiration of the SAR Period); and (C) a Participant's Termination for any other reason, each outstanding unvested SAR granted to such Participant shall immediately terminate and expire, and each outstanding vested SAR shall remain exercisable for 90 days thereafter (but in no event beyond the expiration of the SAR Period).

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(d)<u>Method of Exercise</u>. SARs which have become exercisable may be exercised by delivery of written or electronic notice of exercise to the Company in accordance with the terms of the Award, specifying the number of SARs to be exercised and the date on which such SARs were awarded.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(e)<u>Payment</u>. Upon the exercise of a SAR, the Company shall pay to the Participant an amount equal to the number of shares subject to the SAR that is being exercised multiplied by the excess of the Fair Market Value of one Common Share on the exercise date over the Strike Price, less an amount equal to any Federal, state, local, and non-U.S. income, employment, and any other applicable taxes that are statutorily required to be withheld in accordance with Section 12(d) of the Plan. The Company shall pay such amount in cash, in Class A Ordinary Shares valued at Fair Market Value, or any combination thereof, as determined by the Committee. Any fractional Class A Ordinary Shares shall be settled in cash.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**8.Restricted Share and Restricted Share Units.**

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(a)<u>General.</u> Each grant of Restricted Share and Restricted Share Units shall be evidenced by an Award Agreement. Each Restricted Share and Restricted Share Unit so granted shall be subject to the conditions set forth in this Section 8, and to such other conditions not inconsistent with the Plan as may be reflected in the applicable Award Agreement.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b)<u>Share Certificates and Book-Entry Notation;</u> <u>Escrow</u> <u>or Similar Arrangement</u>. Upon the grant of Restricted Share, the Committee shall, at its discretion, cause a share certificate registered in the name of the Participant to be issued or shall cause Common Share(s) to be registered in the name of the Participant and held in book-entry form subject to the Company's directions and, if the Committee determines that the Restricted Share shall be held by the Company or in escrow rather than issued to the Participant pending the release of the applicable restrictions, the Committee may require the Participant to additionally execute and deliver to the Company

------

&nbsp;&nbsp;&nbsp;&nbsp;(i) an escrow agreement satisfactory to the Committee, if applicable, and (ii) the appropriate share power (endorsed in blank) with respect to the Restricted Share covered by such agreement. If a Participant shall fail to execute and deliver (in a manner permitted under Section 12(a) of the Plan or as otherwise determined by the Committee) an agreement evidencing an Award of Restricted Share and, if applicable, an escrow agreement and blank share power within the amount of time specified by the Committee, the Award shall be null and void. Subject to the restrictions set forth in this Section 8, Section 12(b) of the Plan, and the applicable Award Agreement, a Participant generally shall have the rights and privileges of a shareholder as to Restricted Shares, including, without limitation, the right to vote such Restricted Shares. To the extent Restricted Shares are forfeited, any share certificates issued to the Participant evidencing such shares shall be returned to the Company without undue delay, and all rights of the Participant to such shares and as a shareholder with respect thereto shall terminate automatically without further obligation on the part of the Company. A Participant shall have no rights or privileges as a shareholder as to Restricted Share Units.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(c)<u>Vestin</u>g; <u>Termination</u>.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(i)Restricted Share and Restricted Share Units shall vest, and any applicable Restricted Period shall lapse, in such manner and on such date or dates or upon such event or events as determined by the Committee including, without limitation, those set forth in Section 5(a) of the *Plan;provided, however,* that notwithstanding any such dates or events, the Committee may, in its sole discretion, accelerate the vesting of any Restricted Share or Restricted Share Unit or the lapsing of any applicable Restricted Period at any time and for any reason.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(ii)Unless otherwise determined by the Committee, whether in an Award Agreement or otherwise, in the event of a Participant's Termination for any reason prior to the time that such Participant's Restricted Shares or Restricted Share Units, as applicable, have vested, (A) all vesting with respect to such Participant's Restricted Shares or Restricted Share Units, as applicable, shall cease and (B) unvested shares of Restricted Share and unvested Restricted Share Units, as applicable, shall be forfeited to the Company by the Participant for no consideration as of the date of such Tennination.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(d)<u>Issuance of Restricted Share and Settlement of Restricted Share Units</u>.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(i)Upon the expiration of the Restricted Period with respect to any Restricted Shares, the restrictions set forth in the applicable Award Agreement shall be of no further force or effect with respect to such shares, except as set forth in the applicable Award Agreement. If an escrow arrangement is used, upon such expiration the Company shall issue to the Participant or the Participant's beneficiary, without charge, the share certificate (or, if applicable, a notice evidencing a book-entry notation) evidencing the Restricted Shares which have not then been forfeited and with respect to which the Restricted Period has expired (rounded down to the nearest full share).

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(ii)Unless otherwise determined by the Committee in an Award Agreement or otherwise, upon the expiration of the Restricted Period with respect to any outstanding Restricted Share Units, the Company shall issue to the Participant or the Participant's beneficiary, without charge, one Common Share (or other securities or other property, as applicable) for each such outstanding Restricted Share Unit; *provided, however,* that the Committee may, in its sole discretion, elect to (A) pay cash or part cash and part Class A Ordinary Shares in lieu of issuing only Class A Ordinary Shares in respect of such Restricted Share Units or (B) defer the issuance of Class A Ordinary Shares (or cash or part cash and part Class A Ordinary Shares, as the case may be) beyond the expiration of the Restricted Period if such extension would not cause adverse tax consequences under Section 409A of the Code. If a cash payment is made in lieu of issuing Class A Ordinary Shares in respect of such Restricted Share Units, the amount of such payment shall be equal to the Fair Market Value per Common Share as of the date on which the Restricted Period lapsed with respect to such Restricted Share Units.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(e)<u>Legends on Restricted Share</u>. Each certificate, if any, or book entry representing Restricted Shares awarded under the Plan, if any, shall bear a legend or book-entry notation substantially in the form of the following, in addition to any other information the Company deems appropriate, until the lapse of all restrictions with respect to such Class A Ordinary Shares:

TRANSFER OF THIS CERTIFICATE AND THE SHARES REPRESENTED HEREBY IS RESTRICTED PURSUANT TO THE TERMS OF THE AMBIPAR EMERGENCY RESPONSE 2023 OMNIBUS INCENTIVE PLAN AND A RESTRICTED SHARE AWARD AGREEMENT BETWEEN AMBIPAR EMERGENCY RESPONSE AND THE PARTICIPANT. A COPY OF SUCH PLAN AND AWARD AGREEMENT IS ON FILE AT THE PRINCIPAL EXECUTIVE OFFICES OF AMBIPAR EMERGENCY RESPONSE.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**9.Other Equity-Based Awards and Other Cash-Based Awards.** The Committee may grant Other Equity-Based Awards and Other Cash-Based Awards under the Plan to Eligible Persons, alone or in tandem with other Awards, in such amounts and dependent on such conditions as the Committee shall from time to time in its sole discretion determine including, without limitation, those set forth in Section 5(a) of the Plan. Each Other Equity-Based Award granted under the Plan shall be evidenced by an Award Agreement and each Other Cash-Based Award granted under the Plan shall be evidenced in such form as the Committee may determine from time to time. Each Other Equity-Based Award or Other Cash-Based Award, as applicable, so granted shall be subject to such conditions not inconsistent with the Plan as may be reflected in the applicable Award Agreement or other form evidencing such Award, including, without limitation, those set forth in Section 12(c) of the Plan.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**10.Changes in Capital Structure and Similar Events.** Notwithstanding any other provision in this Plan to the contrary, the following provisions shall apply to all Awards granted hereunder (other than Other Cash-Based Awards):

Any adjustment under this Section 10 shall be conclusive and binding for all purposes.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b)<u>Adjustment Events</u>. Without limiting the foregoing, except as may otherwise be provided in an Award Agreement, in connection with any Adjustment Event, the Committee may, in its sole discretion, provide for any one or more of the following:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(i)substitution or assumption of Awards (or awards of an acquiring company), acceleration of the exercisability of, lapse of restrictions on, or termination of Awards, or a period of time (which shall not be required to be more than ten days) for Participants to exercise outstanding Awards prior to the occurrence of such event (and any such Award not so exercised shall terminate upon the occurrence of such event); and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(ii)subject to any limitations or reductions as may be necessary to comply with Section 409A of the Code, cancellation of any one or more outstanding Awards and payment to the holders of such Awards that are vested as of such cancellation (including, without limitation, any Awards that would vest as a result of the occurrence of such event but for such cancellation or for which vesting is accelerated by the Committee in connection with such event) the value of such Awards, if any, as determined by the Committee (which value, if applicable, may be based upon the price per Common Share received or to be received by other shareholders of the Company in such event), including, without limitation, in the case of an outstanding Option or SAR, a cash payment in an amount equal to the excess, if any, of the Fair Market Value (as of a date specified by the Committee) of the Class A Ordinary Shares subject to such Option or SAR over the aggregate Exercise Price or Strike Price of such Option or SAR (it being understood that, in such event, any Option or SAR having a per share Exercise Price or Strike Price equal to, or in excess of, the Fair Market Value of a Common Share subject thereto may be canceled and terminated without any payment or consideration therefor), or, in the case of Restricted Shares, Restricted Share Units, or Other Equity-Based Awards that are not vested as of such cancellation, a cash payment or equity subject to deferred vesting and delivery consistent with the vesting restrictions applicable to such Restricted Shares, Restricted Share Units, or Other Equity-Based Awards prior to cancellation, or the underlying shares in respect thereof.

------

Payments to holders pursuant to clause (ii) above shall be made in cash or, in the sole discretion of the Committee, in the form of such other consideration necessary for a Participant to receive property, cash, or securities (or combination thereof) as such Participant would have been entitled to receive upon the occurrence of the transaction if the Participant had been, immediately prior to such transaction, the holder of the number of Class A Ordinary Shares covered by the Award at such time (less any applicable Exercise Price or Strike Price).

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(c)<u>Other Requirements</u>. Prior to any payment or adjustment contemplated under this Section 10, the Committee may require a Participant to (i) represent and warrant as to the unencumbered title to the Participant's Awards; (ii) bear such Participant's pro rata share of any post-closing indemnity obligations, and be subject to the same post-closing purchase price adjustments, escrow terms, offset rights, holdback terms, and similar conditions as the other holders of Class A Ordinary Shares, subject to any limitations or reductions as may be necessary to comply with Section 409A of the Code; and (iii) deliver customary transfer documentation as reasonably determined by the Committee.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(d)<u>Fractional Shares</u>. Any adjustment provided under this Section 10 may provide for the elimination of any fractional share that might otherwise become subject to an Award.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(e)<u>Binding Effect</u>. Any adjustment, substitution, determination of value or other action taken by the Committee under this Section 10 shall be conclusive and binding for all purposes.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**11.Amendments and Termination.**

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(a)<u>Amendment and Termination of the Plan</u>. The Board may amend, alter, suspend, discontinue, or terminate the Plan or any portion thereof at any time; *provided,* that no such amendment, alteration, suspension, discontinuance, or termination shall be made without shareholder approval if: (i) such approval is required under Applicable Law; (ii) it would materially increase the number of securities which may be issued under the Plan (except for increases pursuant to Section 5 or 10 of the Plan), or (iii) it would materially modify the requirements for participation in the Plan; *provided, further,* that any such amendment, alteration, suspension, discontinuance, or termination that would materially and adversely affect the rights of any Participant or any holder or beneficiary of any Award theretofore granted shall not to that extent be effective without the consent of the affected Participant, holder, or beneficiary. Notwithstanding the foregoing, no amendment shall be made to the last proviso of Section 11(b) of the Plan without shareholder approval.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b)<u>Amendment of Award Agreements</u>. The Committee may, to the extent consistent with the terms of the Plan and any applicable Award Agreement, in its sole discretion, waive any conditions or rights under, amend any terms of, or alter, suspend, discontinue, cancel, or terminate, any Award theretofore granted or the associated Award Agreement, prospectively or retroactively (including after a Participant's Termination); *provided,* that, other than pursuant to Section 10, any such waiver, amendment, alteration, suspension, discontinuance, cancellation, or termination that would materially and adversely affect the rights of any Participant with respect to any Award theretofore granted shall not to that extent be effective without the consent of the affected Participant; *provided, further,* that without shareholder approval, except as otherwise permitted under Section 10 of the Plan, (i) no amendment or modification may reduce the Exercise Price of any Option or the Strike Price of any SAR; (ii) the Committee may not cancel any outstanding Option or SAR and replace it with a new Option or SAR (with a lower Exercise Price or Strike Price, as the case may be) or other Award or cash payment that is greater than the intrinsic value (if any) of the canceled Option or SAR; and (iii) the Committee may not take any other action which is considered a "repricing" for purposes of the shareholder approval rules of any securities exchange or inter-dealer quotation system on which the securities of the Company are listed or quoted.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**12.General.**

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(a) <u>Award Agreements</u>. Each Award (other than an Other Cash-Based Award) under the Plan shall be evidenced by an Award Agreement, which shall be delivered to the Participant to whom such Award was granted and shall specify the terms and conditions of the Award and any rules applicable thereto, including, without limitation, any Performance Conditions, the effect on such Award of the death, Disability, or Termination of a Participant, or of such other events as may be determined by the Committee. For purposes of the Plan, an Award Agreement may be in any such form (written or electronic) as determined by the Committee (including, without limitation, a Board or Committee resolution, an employment agreement, a notice, a certificate, or a letter) evidencing the Award. The Committee need not require an Award Agreement to be signed by the Participant or a duly authorized representative of the Company.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b)<u>Nontransferabilit</u>y.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(i)Each Award shall be exercisable only by such Participant to whom such Award was granted during the Participant's lifetime, or, if permissible under Applicable Law, by the Participant's legal guardian or representative. No Award may be assigned, alienated, pledged, attached, sold, or otherwise transferred or encumbered by a Participant (unless such transfer is specifically required pursuant to a domestic relations order or by Applicable Law) other than by will or by the laws of descent and distribution and any such purported assignment, alienation, pledge, attachment, sale, transfer, or encumbrance shall be void and unenforceable against any member of the Company Group; *provided,* that the designation of a beneficiary shall not constitute an assignment, alienation, pledge, attachment, sale, transfer, or encumbrance.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(ii)Notwithstanding the foregoing, the Committee may, in its sole discretion, permit Awards (other than Incentive Share Options) to be transferred by a Participant, without consideration, subject to such rules as the Committee may adopt consistent with any applicable Award Agreement to preserve the purposes of the Plan, to: (A) any Person who is a "family member" of the Participant, as such term is used in the instructions to Form S-8 under the Securities Act or any successor form of registration statement promulgated by the Securities and Exchange Commission (collectively, the **<u>"Immediate</u> <u>FamilY. Members");</u>** (B) a trust solely for the benefit of the Participant and the Participant's Immediate Family Members; (C) a partnership or limited liability company whose only partners or shareholders are the Participant and the Participant's Immediate Family Members; or (D) a beneficiary to whom donations are eligible to be treated as "charitable contributions" for federal income tax purposes (each transferee described in clauses (A), (B), (C), and (D) above is hereinafter referred to as a **<u>"Permitted</u> <u>Transferee");</u>** *provided,* that the Participant gives the Committee advance written notice describing the terms and conditions of the proposed transfer and the Committee notifies the Participant in writing that such a transfer would comply with the requirements of the Plan.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(iii)The terms of any Award transferred in accordance with clause (ii) above shall apply to the Permitted Transferee and any reference in the Plan or in any applicable Award Agreement to a Participant shall be deemed to refer to the Permitted Transferee, except that: (A) Permitted Transferees shall not be entitled to transfer any Award, other than by will or the laws of descent and distribution; (B) Permitted Transferees shall not be entitled to exercise any transferred Option unless there shall be in effect a registration statement on an appropriate form covering the Class A Ordinary Shares to be acquired pursuant to the exercise of such Option if the Committee determines, consistent with any applicable Award Agreement, that such a registration statement is necessary or appropriate; (C) neither the Committee nor the Company shall be required to provide any notice to a Permitted Transferee, whether or not such notice is or would otherwise have been required to be given to the Participant under the Plan or otherwise; and (D) the consequences of a Participant's Termination under the terms of the Plan and the applicable Award Agreement shall continue to be applied with respect to the Participant, including, without limitation, that an Option shall be exercisable by the Permitted Transferee only to the extent, and for the periods, specified in the Plan and the applicable Award Agreement.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(c)<u>Dividends and Dividend Equivalents</u>.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(i)The Committee may, in its sole discretion, provide a Participant as part of an Award with dividends, dividend equivalents, or similar payments in respect of Awards, payable in cash, Class A Ordinary Shares, other securities, other Awards or other property, on a current or deferred basis, on such terms and conditions as may be determined by the Committee in its sole discretion, including, without limitation, payment directly to the Participant, withholding of such amounts by the Company subject to vesting of the Award or reinvestment in additional Class A Ordinary Shares, Restricted Shares or other Awards.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(ii)Without limiting the foregoing, unless otherwise provided in the Award Agreement, any dividend otherwise payable in respect of any Restricted Shares that remains subject to vesting conditions at the time of payment of such dividend shall be retained by the Company, remain subject to the same vesting conditions as the Restricted Shares to which the dividend relates and shall be delivered (without interest) to the Participant within 15 days following the date on which such restrictions on such Restricted Shares lapse (and the right to any such accumulated dividends shall be forfeited upon the forfeiture of the Restricted Shares to which such dividends relate).

------

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(iii)To the extent provided in an Award Agreement, the holder of outstanding Restricted Share Units shall be entitled to be credited with dividend equivalent payments (upon the payment by the Company of dividends on Class A Ordinary Shares) either in cash or, in the sole discretion of the Committee, in Class A Ordinary Shares having a Fair Market Value equal to the amount of such dividends (and interest may, in the sole discretion of the Committee, be credited on the amount of cash dividend equivalents at a rate and subject to such terms as determined by the Committee), which accumulated dividend equivalents (and interest thereon, if applicable) shall be payable at the same time as the underlying Restricted Share Units are settled following the date on which the Restricted Period lapses with respect to such Restricted Share Units, and if such Restricted Share Units are forfeited, the Participant shall have no right to such dividend equivalent payments (or interest thereon, if applicable).

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(d)<u>Tax Withholdin</u>g.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(i)A Participant shall be required to pay to the Company or one or more of its Subsidiaries, as applicable, an amount in cash (by check or wire transfer) equal to the aggregate amount of any income, employment, and/or other applicable taxes that are statutorily required to be withheld in respect of an Award. Alternatively, the Company or any of its Subsidiaries may elect, in its sole discretion, to satisfy this requirement by withholding such amount from any cash compensation or other cash amounts owing to a Participant.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(ii)Without limiting the foregoing, the Committee may (but is not obligated to), in its sole discretion, permit or require a Participant to satisfy all or any portion of the minimum income, employment, and/or other applicable taxes that are statutorily required to be withheld with respect to an Award by: (A) the delivery of Class A Ordinary Shares (which are not subject to any pledge or other security interest) that have been both held by the Participant and vested for at least six months (or such other period as established from time to time by the Committee in order to avoid adverse accounting treatment under applicable accounting standards) having an aggregate Fair Market Value equal to such minimum statutorily required withholding liability (or portion thereof); or (B) having the Company withhold from the Class A Ordinary Shares otherwise issuable or deliverable to, or that would otherwise be retained by, the Participant upon the grant, exercise, vesting, or settlement of the Award, as applicable, a number of Class A Ordinary Shares with an aggregate Fair Market Value equal to an amount, subject to clause (iii) below, not in excess of such minimum statutorily required withholding liability (or portion thereof).

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(iii)The Committee, subject to its having considered the applicable accounting impact of any such determination, has full discretion to allow Participants to satisfy, in whole or in part, any additional income, employment, and/or other applicable taxes payable by them with respect to an Award by electing to have the Company withhold from the Class A Ordinary Shares otherwise issuable or deliverable to, or that would otherwise be retained by, a Participant upon the grant, exercise, vesting, or settlement of the Award, as applicable, Class A Ordinary Shares having an aggregate Fair Market Value that is greater than the applicable minimum required statutory withholding liability (but such withholding may in no event be in excess of the maximum statutory withholding amount(s) in a Participant's relevant tax jurisdictions).

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(e)<u>No Claim to Awards; No Rights to Continued</u> <u>Employment;</u> <u>Waiver</u>. No employee of any member of the Company Group, or other Person, shall have any claim or right to be granted an Award under the Plan or, having been selected for the grant of an Award, to be selected for a grant of any other Award. There is no obligation for uniformity of treatment of Participants or holders or beneficiaries of Awards. The terms and conditions of Awards and the Committee's determinations and interpretations with respect thereto need not be the same with respect to each Participant and may be made selectively among Participants, whether or not such Participants are similarly situated. Neither the Plan nor any action taken hereunder shall be construed as giving any Participant any right to be retained in the employ or service of the Service Recipient or any other member of the Company Group, nor shall it be construed as giving any Participant any rights to continued service on the Board. The Service Recipient or any other member of the Company Group may at any time dismiss a Participant from employment or discontinue any consulting relationship, free from any liability or any claim under the Plan, unless otherwise expressly provided in the Plan or any Award Agreement. By accepting an Award under the Plan, a Participant shall thereby be deemed to have waived any claim to continued exercise or vesting of an Award or to damages or severance entitlement related to non-continuation of the Award beyond the period provided under the Plan or any Award Agreement, except to the extent of any provision to the contrary in any written employment contract or other agreement between the Service Recipient and/or any member of the Company Group and the Participant, whether any such agreement is executed before, on, or after the Date of Grant.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(f)<u>International Participants</u>. With respect to Participants who reside or work outside of the United States of America, the Committee may, in its sole discretion, amend the terms of the Plan and create or amend Sub-Plans or amend outstanding Awards with respect to such Participants in order to permit or facilitate participation in the Plan by such Participants, conform such terms with the requirements of Applicable Law or to obtain more favorable tax or other treatment for a Participant or any member of the Company Group.

------

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(g)<u>Des</u>ig<u>nation and Change of Beneficiar</u>y. Each Participant may file with the Committee a written designation of one or more Persons as the beneficiary or beneficiaries, as applicable, who shall be entitled to receive the amounts payable with respect to an Award, if any, due under the Plan upon the Participant's death. A Participant may, from time to time, revoke or change the Participant's beneficiary designation without the consent of any prior beneficiary by filing a new designation with the Committee. The last such designation received by the Committee shall be controlling; *provided, however,* that no designation, or change or revocation thereof, shall be effective unless received by the Committee prior to the Participant's death, and in no event shall it be effective as of a date prior to such receipt. If no beneficiary designation is filed by a Participant, the beneficiary shall be deemed to be the Participant's spouse or, if the Participant is unmarried at the time of death, the Participant's estate.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(h)<u>Tennination</u>. Except as otherwise provided in an Award Agreement, unless determined otherwise by the Committee at any point following such event: (i) neither a temporary absence from employment or service due to illness, vacation, or leave of absence (including, without limitation, a call to active duty for military service through a Reserve or National Guard unit) nor a transfer from employment or service with one Service Recipient to employment or service with another Service Recipient (or vice-versa) shall be considered a Tennination; and (ii) if a Participant undergoes a Termination, but such Participant continues to provide services to the Company Group in a non-employee capacity, including as a consultant, such change in status shall not be considered a Termination for purposes of the Plan. Further, unless otherwise determined by the Committee, in the event that any Service Recipient ceases to be a member of the Company Group (by reason of sale, divestiture, spin-off, or other similar transaction), unless a Participant's employment or service is transferred to another entity that would constitute a Service Recipient immediately following such transaction, such Participant shall be deemed to have suffered a Termination hereunder as of the date of the consummation of such transaction.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(i)<u>No Rights</u> <u>as a</u> <u>Shareholder</u>. Except as otherwise specifically provided in the Plan or any Award Agreement, no Person shall be entitled to the privileges of ownership in respect of Class A Ordinary Shares which are subject to Awards hereunder until such shares have been issued or delivered to such Person.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(j)<u>Government and Other Regulations</u>.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(i)The obligation of the Company to settle Awards in Class A Ordinary Shares or other consideration shall be subject to compliance with Applicable Law. Notwithstanding any terms or conditions of any Award to the contrary, the Company shall be under no obligation to offer to sell or to sell, and shall be prohibited from offering to sell or selling, any Class A Ordinary Shares pursuant to an Award unless such shares have been properly registered for sale pursuant to the Securities Act with the Securities and Exchange Commission or unless the Company has received an opinion of counsel (if the Company has requested such an opinion), satisfactory to the Company, that such shares may be offered or sold without such registration pursuant to an available exemption therefrom and the terms and conditions of such exemption have been fully complied with. The Company shall be under no obligation to register for sale under the Securities Act any of the Class A Ordinary Shares to be offered or sold under the Plan. The Committee shall have the authority to provide that all Class A Ordinary Shares or other securities of any member of the Company Group issued under the Plan shall be subject to such stop-transfer orders and other restrictions as the Committee may deem advisable under the Plan, the applicable Award Agreement and Applicable Law, and, without limiting the generality of Section 8 of the Plan, the Committee may cause a legend or legends to be put on certificates representing Class A Ordinary Shares or other securities of any member of the Company Group issued under the Plan to make appropriate reference to such restrictions or may cause such Class A Ordinary Shares or other securities of any member of the Company Group issued under the Plan in book-entry form to be held subject to the Company's instructions or subject to appropriate stop-transfer orders. Notwithstanding any provision in the Plan to the contrary, the Committee reserves the right to add, at any time, any additional terms or provisions to any Award granted under the Plan that the Committee, in its sole discretion, deems necessary or advisable in order that such Award complies with the legal requirements of any governmental entity to whose jurisdiction the Award is subject.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(ii)The Committee may cancel an Award or any portion thereof if it determines, in its sole discretion, that legal or contractual restrictions and/or blockage and/or other market considerations would make the Company's acquisition of Class A Ordinary Shares from the public markets, the Company's issuance of Class A Ordinary Shares to the Participant, the Participant's acquisition of Class A Ordinary Shares from the Company, and/or the Participant's sale of Class A Ordinary Shares to the public markets, illegal, impracticable, or inadvisable. If the Committee determines to cancel all or any portion of an Award in accordance with the foregoing, the Company shall, subject to any limitations or reductions as may be necessary to comply with Section 409A of the Code:

------

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(A)pay to the Participant an amount equal to the excess of (I) the aggregate Fair Market Value of the Class A Ordinary Shares subject to such Award or portion thereof canceled (determined as of the applicable exercise date, or the date that the shares would have been vested or issued, as applicable), over (11) the aggregate Exercise Price or Strike Price (in the case of an Option or SAR, respectively) or any amount payable as a condition of issuance of Class A Ordinary Shares (in the case of any other Award), with such amount being delivered to the Participant as soon as practicable following the cancellation of such Award or portion thereof or

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(B)in the case of Restricted Shares, Restricted Share Units, or Other Equity-Based Awards, provide the Participant with a cash payment or equity subject to deferred vesting and delivery consistent with the vesting restrictions applicable to such Restricted Shares, Restricted Share Units, or Other Equity-Based Awards, or the underlying shares in respect thereof.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(k)<u>No Section 83(b)</u> <u>Elections</u> <u>Without Consent of Company</u>. No election under Section 83(b) of the Code or under a similar provision of law may be made unless expressly permitted by the terms of the applicable Award Agreement or by action of the Committee (or its designee in accordance with Section 4(c) of the Plan) in writing prior to the making of such election. If a Participant, in connection with the acquisition of Class A Ordinary Shares under the Plan or otherwise, is expressly permitted to make such election and the Participant makes the election, the Participant shall notify the Company of such election within ten days of filing notice of the election with the Internal Revenue Service or other governmental authority, in addition to any filing and notification required pursuant to Section 83(b) of the Code or other applicable provision.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(1)&nbsp;&nbsp;&nbsp;&nbsp;<u>Payments to Persons Other Than Participants</u>. If the Committee shall find that any Person to whom any amount is payable under the Plan is unable to care for the Participant's affairs because of illness or accident, or is a minor, or has died, then any payment due to such Person or the Participant's estate (unless a prior claim therefor has been made by a duly appointed legal representative) may, if the Committee so directs the Company, be paid to the Participant's spouse, child, relative, an institution maintaining or having custody of such Person, or any other Person deemed by the Committee to be a proper recipient on behalf of such Person otherwise entitled to payment. Any such payment shall be a complete discharge of the liability of the Committee and the Company therefor.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(m)<u>Nonexclusivity of the Plan</u>. Neither the adoption of the Plan by the Board nor the submission of the Plan to the shareholders of the Company for approval shall be construed as creating any limitations on the power of the Board to adopt such other incentive arrangements as it may deem desirable, including, without limitation, the granting of equity-based awards otherwise than under the Plan, and such arrangements may be either applicable generally or only in specific cases.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(n)<u>No Trust or Fund Created</u>. Neither the Plan nor any Award shall create or be construed to create a trust or separate fund of any kind or a fiduciary relationship between any member of the Company Group, on the one hand, and a Participant or other Person, on the other hand. No provision of the Plan or any Award shall require the Company, for the purpose of satisfying any obligations under the Plan, to purchase assets or place any assets in a trust or other entity to which contributions are made or otherwise to segregate any assets, nor shall the Company be obligated to maintain separate bank accounts, books, records, or other evidence of the existence of a segregated or separately maintained or administered fund for such purposes. Participants shall have no rights under the Plan other than as unsecured general creditors of the Company, except that insofar as they may have become entitled to payment of additional compensation by performance of services, they shall have the same rights as other service providers under general law.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(o)<u>Reliance on Reports</u>. Each member of the Committee and each member of the Board shall be fully justified in acting or failing to act, as the case may be, and shall not be liable for having so acted or failed to act in good faith, in reliance upon any report made by the independent public accountant of any member of the Company Group and/or any other information furnished in connection with the Plan by any agent of the Company or the Committee or the Board, other than himself or herself.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(p)<u>Relationship to Other Benefits</u>. No payment under the Plan shall be taken into account in determining any benefits under any pension, retirement, profit sharing, group insurance, or other benefit plan of the Company except as otherwise specifically provided in such other plan or as required by Applicable Law.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(q)<u>Governing Law</u>. THIS PLAN AND ITS ENFORCEMENT AND ANY CONTROVERSY ARISING OUT OF OR RELATING TO ANY RIGHTS AND OBLIGATIONS HEREUNDER SHALL BE GOVERNED BY AND CONSTRUED IN

ACCORDANCE WITH THE LAWS OF THE CAYMAN ISLANDS. Each Participant who accepts an Award hereby (i) agrees that any action, directly or indirectly, arising out of, under or relating to the Plan or any Award hereunder shall exclusively be brought in and shall exclusively be heard and determined by either the Supreme Court of the State of New York sitting in Manhattan or the United States District Court for the Southern District of New York, and (ii) solely in connection with the action(s) contemplated by subsection

&nbsp;&nbsp;&nbsp;&nbsp;(i) hereof, (A) irrevocably and unconditionally consents and submits to the exclusive jurisdiction of the courts identified in subsection

------

&nbsp;&nbsp;&nbsp;&nbsp;(i) hereof, (B) irrevocably and unconditionally waives any objection to the laying of venue in any of the courts identified in clause (i) of this Section 12(q), (C) irrevocably and unconditionally waives and agrees not to plead or claim that any of the courts identified in such clause (i) is an inconvenient forum or does not have personal jurisdiction over such Participant or any member of the Company Group, and (D) agrees that mailing of process or other papers in connection with any such action in the manner provided herein or in such other manner as may be permitted by Applicable Law shall be valid and sufficient service thereof. EACH PARTICIPANT WHO ACCEPTS AN AWARD IRREVOCABLY WAIVES ALL RIGHT TO A TRIAL BY JURY IN ANY SUIT, ACTION, OR OTHER PROCEEDING INSTITUTED BY OR AGAINST SUCH PARTICIPANT IN RESPECT OF THE PARTICIPANT'S RIGHTS OR OBLIGATIONS HEREUNDER.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(r)<u>Severabilit</u>y.

## Exhibit 11.2

**Exhibit 11.2**

**POLICIES AND PROCEDURES FOR TRADING IN SECURITIES** 

**OF AMBIPAR EMERGENCY RESPONSE BY ACCESS INSIDERS**

Ambipar Emergency Response and its entities directly or indirectly controlled (collectively, the "**Company**") are committed to fair trading and the SEC and the New York Stock Exchange rules and regulations (including those applicable to the NYSE American).

To avoid any situation where an Access Insider (as defined below) is in an asymmetrical trading position *vis a vis* an investor of the Company, the Company has adopted this policy and procedures applicable to Access Insiders. The procedures in this policy should be interpreted in the context of all applicable laws and the Company's other policies and procedures (each as they may be amended, restated and in effect at the relevant time). It is expected that these procedures will be reviewed by the Company from time to time to ensure that they comply with all applicable laws, and regulations, and as the Company deems appropriate.

1. GENERAL

&nbsp;&nbsp;&nbsp;&nbsp;These policies and procedures (together, this "**Policy**") govern trading activity in securities of the Company by directors, executive officers, and all regular employees with managerial functions of the Company or of Ambipar Participações e Empreendimentos S.A. that provide administrative services to the Company, and any other persons the Company determines should be subject to this policy (together, the "**Access Insiders**"). This Policy also applies to the immediate family members of the Company's Access Insiders. Immediate family members include spouse, parents, children, siblings, mothers and fathers-in-law, sons and daughters-in-law, brothers and sisters-in-law, and anyone (other than tenants and domestic employees) who shares such person's home.

If you have any question about whether you are subject to this Policy, please contact the Company's Chief Investor Relations Officer.

The SEC defines purchases and sales to include an extensive list of transactions beyond simple open-market transactions to buy or sell the Company's securities. Also included, for example, are the granting of options in the Company's securities as well as the acquisition of or disposition of interests in the Company's securities through various company benefit plans. Dispositions of securities include the sale of these securities as well as gift transfers. This Policy, therefore, relates and applies to all transactions involving any securities of the Company by Access Insiders (including pledge of Company's securities to secure a loan or margin account) or tipping of any such transaction by Access Insiders, whether or not the transaction is a purchase or sale in the usual sense, and whether or not the security is common shares, preferred shares or another security, such as an option, except as set forth in the paragraph immediately below.

The prohibition on trading Company's securities set forth in this Policy shall not apply to: (i) the transfer of securities to an entity that does not involve a change in the beneficial ownership of the securities, (ii) the exercise of stock options or similar incentive plan for cash under the Company's benefit plans, however, the **<u>sale</u>** of any such stock acquired upon such

------

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;

exercise, including as part of a cashless exercise of an option, is subject to this Policy, (iii) the execution of transactions pursuant to a trading plan that complies with SEC Rule 10b5-1 and which has been approved by the Company and (iv) sales of the Company's securities as selling stockholder in a registered public offering in accordance with applicable securities laws.

For the purposes of this Policy, (i) an information shall be deemed "material" as per the criteria provided for in the Policy and Procedures for Disclosure of Material Information, and (ii) an information shall be deemed "inside information" if it has not been publicly disclosed as provided for in the Policy and Procedures for Disclosure of Material Information.

2. TRADING WINDOWS

We have established four "windows" of time for each fiscal year during which Access Insiders may engage in transactions involving securities of the Company.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• *A window period begins* at the opening of trading on the first trading day after at least one full trading day on the New York Stock Exchange, or the NYSE American, as the case may be, after the day on which the Company issues a public news release of its quarterly or annual earnings for the prior fiscal quarter or year. Assuming the New York Stock Exchange or the NYSE American, as the case may be, is open each day, the following example illustrates when Access Insiders may trade after the Company's public news release of its quarterly or annual earnings for the prior fiscal quarter or year:

<u>Timing of Announcement on Tuesday</u>&nbsp;&nbsp;&nbsp;&nbsp;<u>First Day of Trading</u>

Before market opens&nbsp;&nbsp;&nbsp;&nbsp;Wednesday

While market is open&nbsp;&nbsp;&nbsp;&nbsp;Thursday

After market closes&nbsp;&nbsp;&nbsp;&nbsp;Thursday

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• *That same trading window closes* by the end of the last trading day of the current fiscal quarter. After the close of the window period, Access Insiders may not purchase, sell, gift or otherwise acquire, transfer or dispose of any of the Company's securities.

**The prohibitions against trading while aware of, or tipping, material, non-public information and short-term trading apply even during a trading window**. Thus, no Access Insider shall be authorized to trade with the Company's securities in the possession of material inside information not yet disclosed as per the Policy and Procedures for Disclosure of Material Information, even during trading windows. For example, if you are aware that a material acquisition or divestiture is pending or that a forthcoming publication in the financial press may affect the relevant securities market, you may not trade in the Company's securities. *The Company also may close regular window periods if any such event occurs, and you will receive a notification from the Chief Investor Relations Officer or his or her designee when this occurs.* Closing of a regular window period should be considered to be confidential information, and may not be shared with anyone, other than one's legal and financial advisers or to the extent necessary to notify others of their obligations under this Policy.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;

------

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;

This Policy shall apply during the period when a person is an Access Insider and for the first three months after the person is no longer an Access Insider.

3. PRE-APPROVAL

Individuals holding certain positions within the Ambipar group identified on Annex 1 hereto ("<u>Permanent Restricted Persons</u>") are required to notify the Chief Investor Relations Officer or his or her designee each proposed transaction in accordance with the approval process described below <u>before</u> the transaction is consummated.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• The exceptions to this requirement are: (i) any transaction pursuant to a pre-existing and approved written plan or arrangement complying with Rule 10b5-1 promulgated under the Securities Exchange Act of 1934, as amended (the "**Exchange Act**") and approved in advance by the Chief Investor Relations Officer, (ii) transfer of securities to an entity that does not involve a change in the beneficial ownership of the securities and (iii) the exercise of stock options for cash under the Company's benefit plans.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• **Requests for approval may only be submitted, and approval for trades and gifts of securities of the Company will generally be granted, only during a window period, and an approved transaction may only be performed within two (2) business days of any such grant or approval during the window period in which the approval was granted**.

With respect to any Permanent Restricted Person in possession of any material inside information pertaining to the Company, the limitations under this Policy shall be extended until such material inside information is disclosed to the market in accordance with the Policy and Procedures for Disclosure of Material Information.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• It is therefore the responsibility of each Permanent Restricted Person and each former Permanent Restricted Person, during his or her employment and for a period of three months after leaving such position, to submit notification to the Chief Investor Relations Officer or his or her designee at least one week in advance of any proposed transaction by such Permanent Restricted Person.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Such notice, which shall be accomplished by submission of the information contained in the written Transaction Questionnaire attached hereto as <u>Exhibit A via e-mail to</u> the Chief Investor Relations Officer, shall describe fully the details of the proposed transaction, including the nature of the transaction, the number of shares or other securities and the parties involved.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Before the transaction is actually consummated, there shall be confirmation from the Chief Investor Relations Officer or his or her designee that the transaction is not restricted under the terms of this Policy.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• The Chief Investor Relations Officer or his or her designee shall respond within two (2) business days of the receipt of the notice.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• The Chief Investor Relations Officer or his or her designee may revoke any approval previously granted if she or he subsequently determines that a Permanent Restricted Person is in possession of material, non-public information about the Company or such transaction would result in a violation of law.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;

------

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• If the transaction is not approved or approval for such transaction has been revoked, then the proposed transaction may not be conducted.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Permanent Restricted Persons shall promptly (and, in any event, by the close of the business day after the day during which the transaction occurred) notify the Chief Investor Relations Officer of any trading of the Company's securities.

4. ANNUAL CERTIFICATION
