In 2018, our energy business, which is part of the Value Recovery segment, was classified as discontinued operations, and as a result of that classification, the statement of profit and loss for the years ended December 31, 2017, 2016, 2015 and 2014 have been restated for comparative purposes. See note 1.5.1 to our audited financial statements included elsewhere in this annual report.

(2)

Solely for the convenience of the reader, the amounts in reais for the year ended December 31, 2018 has been translated into U.S. dollars using the rate of R$3.8742 per U.S. dollar, which was the commercial selling rate for U.S. dollars as of December 31, 2018, as reported by the Central Bank. These translations should not be considered representations that any such amounts have been, could have been or could be converted into U.S. dollars at that or any other exchange rate. See “—Exchange Rate Information” below.

(3)

Given that the Registrant is a new parent entity established to effect a share for share exchange in connection with the Transaction, and its audited financial statements have been presented as a continuation of the existing group, the number of shares taken as being issued for both the current and preceding periods was the number of shares issued by the new parent entity (Estre Ambiental, Inc.). In the calculation of earnings per share for the year ended December 31, 2016 presented in the audited financial statements, there were no changes in the number of outstanding ordinary shares of Estre Ambiental S.A. for that period that should be reflected in the calculation. Therefore, the weighted average number of shares was the same for all periods.

(4)

The calculation of basic earnings (loss) per share is based on the net income attributable to controlling equity holders of the Registrant and the proportional weighted average number of shares outstanding during the year. Diluted earnings per share is based on the net income attributable to controlling equity holders, as adjusted by the weighted average number of shares outstanding during the year assuming conversion of all potentially dilutive shares. For additional information, see note 34 to our audited financial statements included elsewhere in this annual report.

Exchange Rate Information

The Brazilian foreign exchange system allows the purchase and sale of foreign currency and the international transfer of reais by any person or legal entity, regardless of the amount, subject to certain regulatory procedures.

Since 1999, the Central Bank has allowed the U.S. dollar-real exchange rate to float freely. Since then, the U.S. dollar-real exchange rate has fluctuated considerably.

The Central Bank has intervened occasionally to control unstable movements in foreign exchange rates. We cannot predict whether the Central Bank or the Brazilian government will continue to permit the real to float freely or will intervene in the exchange rate market through the return of a currency band system or otherwise. See “—D. Risk Factors—Risks Related to Brazil—The Brazilian economy and we may be negatively impacted by exchange rate instability.”

The real may depreciate or appreciate against the U.S. dollar substantially. See “—D. Risk Factors—Risks Related to Brazil—The Brazilian economy and we may be negatively impacted by exchange rate instability.”

Furthermore, Brazilian law provides that, whenever there is a serious imbalance in Brazil’s balance of payments or there are substantial reasons to foresee a serious imbalance, the Brazilian government may impose temporary restrictions on the remittances of foreign capital abroad and on the conversion of Brazilian currency into foreign currencies. We cannot assure you that such measures will not be taken by the Brazilian government in the future. See “—D. Risk Factors—Risks Related to Brazil—The Brazilian economy and we may be negatively impacted by exchange rate instability.”

For convenience purposes only, the amounts in reais for the year ended December 31, 2018 presented throughout this annual report have been translated to U.S. dollars using the rate R$3.8742 per U.S. dollar, which was the commercial selling rate for U.S. dollars as of December 31, 2018, as reported by the Central Bank. These translations should not be considered representations that any such amounts have been, could have been or could be converted into U.S. dollars at that or any other exchange rate. Therealhas fluctuated significantly over the course of 2018 due in part to the general strengthening of the U.S. dollar worldwide and reflecting lower Brazilian interest rates and a high degree of political uncertainty.

The following table shows the period end, average, high and low commercial sellingreal/U.S. dollar exchange rate reported by the Central Bank on its website for the periods and dates indicated.

D.	Risk Factors

An investment in our ordinary shares carries a significant degree of risk. You should carefully consider the following risks and other information in this annual report, including our audited financial statements included elsewhere in this annual report, before you decide to purchase our ordinary shares. Additional risks and uncertainties of which we are not presently aware or that we currently deem immaterial could also affect our business operations and financial condition. If any of these risks actually occur, our business, financial condition, results of operations or prospects could be materially affected. As a result, the trading price of our ordinary shares could decline and you could lose part or all of your investment.

Risks Related to Our Business

We may lose contracts through competitive bidding or be required to substantially lower prices in order to retain certain contracts, which could negatively impact our revenues.

We derive a significant portion of our revenues from markets in which we have exclusive arrangements pursuant to municipal contracts. Our municipal contracts are for a specified term and are, or will be, subject to competitive bidding in the future. Although we intend to bid on additional municipal contracts in our target markets from time to time if and when suitable opportunities arise, we may not, if ever, be successful in winning bids, especially considering the significant increase in competitivity and margin compression in the market during the course of 2018. In addition, municipalities may unilaterally terminate any agreements on grounds of serving the public interest. If we are unable to replace revenue from contracts lost through competitive bidding or early termination or from lowering prices pursuant to the competitive bidding process for existing contracts, our revenues could decline.

Governmental action may also affect our exclusive arrangements. Municipalities may decide to develop their own landfills, on an optional or mandatory basis, which may cause us to lose customers. If we are not able to replace lost revenues within a reasonable time period, our business results of operations and financial condition could be adversely affected. Additionally, the loss of municipal contracts through competitive bidding, early termination or governmental action could cause long lived tangible and intangible assets to be impaired and require a charge against earnings.

In addition, the risks described under “—Risks Related to Compliance and Control” have caused, and may in the future cause, us to be unable to participate in certain competitive bidding processes, which may cause a significant decline in our revenues. For example, Estre was classified as a Compliance High Risk Supplier by Petrobras in the past and, as such, was not permitted to participate in certain of Petrobras’ bidding processes.

A significant portion of our revenue is derived from a small number of customers, and partial or full loss of revenues from any such customer may adversely affect our revenues and results of operations. In particular, the municipality of São Paulo is currently serviced based on a short-term temporary contract which will end on June 1, 2019. The loss of business from the São Paulo contract will have a material adverse impact on us.

Our customer base includes a mix of customers operating in both the private and public sectors. As of December 31, 2018, we had 138 municipal customers and more than 3,000 private sector customers, serving approximately 31 million individual customers daily. Although we have a diversified customer base across our four business segments, our top 13 customers accounted for 72.9% of our total net revenue in the year ended December 31, 2018. In addition, our top 5 costumers represent 38.2% of our revenue from the Landfills segment, totaling 12.1% of our total net revenue and 8 customers accounted for 93.7% or more of our revenue from the Collection & Cleaning segment, totaling 60.7% of total net revenue in the year ended December 31, 2018.

In addition, we rely significantly on certain municipal customers within our Collection & Cleaning segment as a source of revenues, namely the municipalities of São Paulo and Curitiba. Together, our contracts with the municipalities of São Paulo and Curitiba represented 79.0% of the net revenues from services rendered for the Collection & Cleaning segment for the year ended December 31, 2018, and 39.9% of our total net revenues from services that year. Competitive bidding processes are inherently subject to a high degree of uncertainty, and there can be no guarantee that past practices will be indicative of future success. As described below under “—Our contract with the municipality of São Paulo”, we will no longer provide services in São Paulo as of June 1, 2019 when our emergency temporary contract will be terminated. As described below under “Our contract with the municipality of Curitiba”, our contract with Curitiba has been renewed and we signed a five-year contract on January 3, 2019.

Moreover, we cannot assure you that we will be the successful bidder in bidding processes for any other competitive bidding process we participate in. In addition, even if we are successful in the bidding process and enter into new contracts with our most significant customers, the terms of the contracts might differ and might not be as favorable to us as those contracts currently in place, resulting in less revenue from these customers. The loss or adverse modification of any material customer contract could have a material adverse effect on our business, results of operations and financial condition.

While Brazilian law does not allow the term extension of government contracts already expired, public administrators may exercise their right to hire the same contractor on a provisional basis for a temporary period based on a waiver of the bidding process. Provisional service pursuant to a temporary contract may be with any service provider, not just the last serving contractor. These temporary contracts must be limited to a180-day term, counted as of the occurrence of the exceptional circumstances giving rise to the auction delay, and may be terminated by the municipality at its discretion at any time, including as a result of the conclusion of the formal bidding process. As a general rule, temporary contracts entered into on an emergency basis may not be extended. However, as the collection of MSW is considered an essential service under Brazilian law, once the initial180-day period expires on a temporary contract, municipalities may continue to extend for subsequent180-day periods.

Our contract with the municipality of São Paulo

We have been servicing the São Paulo contract through Soma since 2011. Our contract with the municipality of São Paulo for urban cleaning and street sweeping services represented approximately 25.5% of our revenues in 2018 (29.1% of our revenues in 2017). This contract expired in the end of 2017, and we are currently providing urban cleaning services to the city of São Paulo pursuant to a temporary contract. The temporary contract was first entered into on December 15, 2017 and expired in June 2018. On June 12, 2018, we further extended the temporary contract until the end of 2018. In December 2018, we further extended the temporary contract until the end of May 2019 and, on May 2, 2019, we were informed that our emergency contract with the municipality of São Paulo will be terminated on June 1, 2019, at which point we will no longer provide services in São Paulo. The extended temporary contract introduced in June 2018 certain significant changes to the contractual arrangement. Most significantly, under the extended temporary contract, the city of São Paulo has been divided into six separate parcels for urban cleaning, whereas under the previous contract the city had been divided into two parcels only. We, through Soma, were awarded only two parcels under the extended temporary contract, which reflects a significant decrease of our service area, since we previously serviced one of the only two parcels. As a result these changes, monthly revenues under the extended temporary contract decreased approximately 40% starting in June 2018 and as a result our revenues from the contract with the municipality of São Paulo for urban cleaning and street sweeping services decreased to approximately 31.8% of our revenues in 2018.

Considering the significance of the São Paulo contract in terms of revenues, it can be expected that our revenues will materially decrease upon the termination of the contract. According to management estimates, and based on our original revenue expectations for 2019, the impact of losing the São Paulo contract on an annualized basis will result in an estimated decrease in revenues of 25.1%.

A relevant part of our operational structure is designed to serve the São Paulo contract and, upon its termination, we will be required to significantly reallocate resources, including the termination of employees currently servicing this contract and/or closure of certain facilities and projects solely related to our current operations in São Paulo, all of which will have a cash impact in the short-term of approximately R$22 million, which amount is stated after taking account of the cash expected to be generated from the sale of assets previously used in such operation. Furthermore, given the medium and long term nature of the majority of our contracts, we will not have the flexibility to immediately offset a decrease in revenues by increasing prices. Given the staggered timing of attractive competitive bidding opportunities occurring only on an intermittent basis as existing contracts come due, we will likely face challenges to quickly replace the lost revenues with new collections business. Given the size of the city of São Paulo, being the largest city in Brazil in terms of population according to 2017 IBGE data, we would likely have to secure several smaller contracts to replace the revenues lost under the contract. The significant loss of revenues could, in turn, impact our ability to comply with the covenants under any of our indebtedness or make payments as they come due.

Our contract with the municipality of Curitiba

Cavo, which we acquired in 2011, has been servicing the Curitiba contract since 1995. Our contract with the municipality of Curitiba for collections, urban cleaning and street cleaning comprised approximately 12.0% of the Company’s revenues in 2018 (12.5% in 2017). In October 2018, we won the competitive bidding process for the Curitiba collections and cleaning contract. We signed a five-year contract on January 3, 2019 with a maximum value of R$844.8 million (a reduction in price of approximately 14.1% compared with the previous contract) and are currently providing the contractual services to Curitiba. In connection to the new contract, we are required to incur in expenses in order to comply with the terms of the new contract, which could further affect our short-term liquidity and therefore impact our ability to make payments as they become due.

As of December 31, 2018 we recorded significant negative working capital and capital deficiency, we are currently in breach of certain financial covenants and contractual obligations, and our ability to avoid a judicial reorganization is dependent on our ability to successfully complete a debt restructuring and significantly improve our liquidity position

We incurred net losses from continuing operations of R$720.9 million and R$364.2 million in the years ended December 31, 2018, and 2016, respectively, and while we recorded profits from continuing operations of R$37.9 million in 2017, such results were primarily driven by the gains recorded under deferred income and social contribution taxes as a result of our recognition of tax loss carryforwards in connection with our participation in the Brazilian Tax Regularization Program. As of December 31, 2018, we recorded negative working capital (calculated as total current assets minus total current liabilities) of R$1,289.8 million and a capital deficiency (calculated as total assets minus total liabilities) of R$1,149.2 million. As of December 31, 2017, we recorded working capital of R$293.4 million and a capital deficiency of R$455.9 million, and as of December 31, 2016, we recorded negative working capital of R$1,366.2 million and a capital deficiency of R$737.1 million.

As a result of liquidity constraints, the Company was not able to comply with the financial covenants included in its Debt Instruments for the year ended on December 31, 2018 and we are currently in breach of such covenants. In addition, on March 6, 2018, Angra confirmed the exercise of its put option to sell all of its shares of the Company. While we were required to pay the exercise price of approximately R$40.3 million by September 6, 2018, as of the date of this annual report, we have not yet made any payments to Angra due to our liquidity constraints, and the rescheduled payment terms are still being negotiated. See “Major Shareholders and Related Party Transactions—Share Put Option Agreement” and “—We are in default under the Angra Put Option Agreement, and if we are unable to reach an agreement with Angra to resolve the default, Angra can exercise remedies against us” below. Our management has identified several significant obligations arising during 2019 that require funding through liquidity, primarily relating to (a) the payments we are required to make for severance and other demobilization costs related to discontinued operations (for example, the contract with the municipality of São Paulo for cleaning services, which will be terminated on June 1, 2019, at which point we will no longer provide services in São Paulo) and (b) capital expenditures (e.g., new trucks and equipment) required in connection with contract renewals, such as the investment obligations arising under the contract with the municipality of Curitiba for cleaning services, which was renewed on January 3, 2019 for an additional five year period. Furthermore, as of December 31, 2018, the Company had aggregate overdue trade accounts of R$85.9 million, and there can be no assurance that such trade creditors will not demand immediate payment or use a variety of legal remedies to enforce their claims, which may further constrain our liquidity, further jeopardize our ability to continue as a going concern and increase the risk that we become subject to bankruptcy proceedings.

We are engaged in efforts to generate liquidity in order to improve our liquidity position and fund our obligations, including negotiations in respect of the sale of certain assets, which sales will likely require the approval of the holders of our Debt Instruments. In addition, the Company, with the approval of our board of directors, has initiated negotiations with the holders of the Debt Instruments, as well as other relevant creditors including Angra, with the goal of restructuring its financial and such other debt. In that regard, the Company engaged an outside restructuring advisor as well as outside legal counsel to advise in connection with the debt restructuring process. The Company is currently seeking to conclude the debt restructuring process in the course of 2019.

There can be no assurance that the debt restructuring process will be successful or that we will be able to generate sufficient liquidity in order to fully address our liquidity concerns. Our inability to significantly improve our liquidity position and comply with our financial covenants and other payment obligations, including overdue amounts owed to trade creditors, could have a material adverse effect on us and result in an extrajudicial reorganization or a judicially-supervised reorganization process, which may result in our shareholders losing their entire investment.

We have a significant level of indebtedness, including debt issued pursuant to the Debt Instruments, which is secured by a significant amount of our assets and contains financial covenants; we are currently in breach of our financial covenants and such breach and our high level of indebtedness generally may materially adversely affect us and our ability to successfully implement our strategic plan and continue our operations and may result in our bankruptcy.

We have substantial indebtedness. As of December 31, 2018, our total financial indebtedness, consisting primarily of outstanding balances on our debentures and working capital loans and, to a lesser extent, BNDES loans and financings and finance leases, was R$1,594.7 million, as compared to R$1,454.5 million and R$1,692.3 million as of December 31, 2017 and 2016, respectively. Of these total amounts, 97.6% of our total indebtedness was linked to floating rates as of December 31, 2018 as compared to 98.7% and 99.1% as of December 31, 2017 and 2016, respectively.

Furthermore, a significant part of our assets have been pledged as collateral to secure repayment of the Refinanced Debt. The Refinanced Debt is secured by collateral consisting of: (i) a lien on all real estate relating to the operational landfills; (ii) a lien on all material subsidiaries controlled, directly or indirectly, by us; (iii) a fiduciary assignment of the remaining balance originated from the foreclosure of liens described in this paragraph; and (iv) corporate guarantees of all material subsidiaries controlled, directly or indirectly, by us. The debt admission instrument related to our first issuance of debentures is also secured by a fiduciary assignment of certain real estate assets owned by us. In addition, the Refinanced Debt is secured by a fiduciary lien on all (except for 4.38% secured for the benefit of Angra) of the Company’s common shares as security for the payment of all obligations related to the Refinanced Debt. For further information, see “Item 5.B. Operating Financial Review and Prospects —Indebtedness—Debentures—Debt Restructuring and Refinanced Debt.”

The Debt Instruments also contain financial and other covenants. In particular, they require us to maintain certain financial ratios, which are measured semi-annually as of June 30 and December 31 of each year, on a Company consolidated basis, starting on December 31, 2018. As of December 31, 2018, the Company did not comply with its financial covenants, i.e. (i) the Company’s consolidated annual net debt to EBITDA ratio was 7.9x and exceeded the permitted maximum ratio of 4.0x, and (ii) the debt service coverage ratio of the Company was negative 15.6x, below the mimimum ratio of 1.2x. As a consequence of ournon-compliance with the financial covenants under the Debt Instruments, lenders are entitled to accelerate the debt obligations. The Company has initiated negotiations with the holders of its Debt Instruments and we currently do not expect that the relevant creditors will accelerate the debt obligations in the near future. However, the lenders have not provided any formal waivers with respect to thenon-compliance of the financial covenants.

Our high amount of indebtedness, related collateral and the breach of the financial covenants set forth in our Debt Instruments:

•

entitles the holders of our debentures to accelerate the debt obligations and may result in the execution against any collateral securing such indebtedness;

•

may result in cross-defaults under our other indebtedness, which in turn could result in the acceleration of our other indebtedness and in the execution against any collateral securing such indebtedness;

•

could force us to undergo a judicial reorganization or result in our bankruptcy;

•

increases our vulnerability to general adverse economic and industry conditions and an increase in interest rates;

•

limits our ability to obtain additional financing or refinancing on acceptable terms or at all;

•

may force us to reduce or delay capital expenditures, sell assets, restructure or refinance all or part of our existing debt, or seek additional equity capital, any of which may not be available on terms that are favorable to us or to our shareholders, if at all;

•

will, once the grace period for the payment of interest in cash in respect of the Refinanced Debt expires in December 2019 and once our grace period for the payment of principal of the Refinanced Debt expires in December 2020, require the dedication of a substantial portion of our cash flow from operations to the payment of interest on, and principal of, our indebtedness, thereby reducing the availability of such cash flow to fund our operations;

•

limits our flexibility in planning for, or reacting to, changes in our business and the industry; and

•

places us at a competitive disadvantage relative to our competitors with less debt.

Considering our unsustainably high level of indebtedness and the breach of the financial covenants set forth in our Debt Instruments, we are engaged in efforts to improve our financial position. In that regard, the Company, with the approval of our board of directors, has initiated negotiations with the holders of the Debt Instruments, as well as other relevant creditors such as Angra with the goal of restructuring its financial and such other debt. The Company engaged an outside restructuring advisor as well as outside legal counsel to advise in connection with the debt restructuring process. The Company is currently seeking to conclude the debt restructuring process during the course of 2019. However, there can be no assurance that the debt restructuring process will be successful or that we will be able to otherwise address our high level of indebtedness and distressed financial situation. Our inability to do so may result in our bankruptcy, which may result in our shareholders losing their entire investment.

We are in default under the Angra Put Option Agreement, and if we are unable to reach an agreement with Angra to resolve the default, Angra can exercise remedies against us.

On March 6, 2018, our former shareholder Angra confirmed the exercise of its put option to sell all of its shares of the Company. As a result of such exercise, Angra transferred 8,871,895 shares to the Company, which are currently held in treasury, and we were required to pay the exercise price of approximately R$40.3 million by September 6, 2018. However, as of the date of this annual report, as a result of our liquidity constraints, we have not yet made any payments to Angra with respect to the share transfer, but are negotiating alternative payment terms with Angra.

On September 11, 2018, we received a letter from Angra stating that we are in default under the Angra Put Option Agreement as a result of our failure to pay the put option amount when due and that additional amounts may be due to Angra because of our default, including default interest payments. We are in ongoing negotiations with Angra regarding the payment terms, which are conducted concurrently with our efforts to restructure our Debt Instruments and part of our larger debt restructuring efforts. There are no assurances that our negotiaions with Angra will be successful and Angra has reserved all of its rights, remedies, actions and powers to which it may be legally entitled. As a result, Angra may seek certain remedies afforded to them under the Angra Put Option Agreement and otherwise under Brazilian law, including the enforcement of their security interest of 4.38% of the share capital of the Company.

Our default under the Angra Put Option Agreement, if not cured, could also constitute an event of default under the cross-default provisions of our other indebtedness. If a default occurs under the Debt Instruments, in particular, the holders of such debt could accelerate the indebtedness, demand immediate payment and use a variety of legal remedies to enforce their claims. If any of these defaults and the acceleration of any of our debt were to occur, it is unlikely that we would be able to continue as a going concern and we may have to declare, or be forced into bankruptcy.

Our auditors have issued a “going concern” audit opinion, and our ability to continue as a going concern is dependent on our ability to significantly improve our liquidity position

Our management has concluded that substantial doubt exists with respect to our ability to continue as a going concern through one year after the date of issuance of our audited financial statements as of and for the year ended December 31, 2018. In addition, as a result of our material liquidity issues, our independent auditors have indicated, in their report on our audited financial statements that there exists significant uncertainty that could raise doubt about our ability to continue as a going concern. These doubts regarding our ability to continue as a going concern relate to our history of suffering recurring losses from operations, the ongoing process of renegotiating our debt obligations and our net capital deficiency, resulting in substantial doubt as to our ability to continue as a going concern.The audited financial statements do not include any adjustments that might be necessary if we are unable to continue as a going concern.

Our liquidity and our ability to continue as a going concern is dependent on various factors, including our ability to successfully complete a debt restructuring and generate additional liquidity through asset sales, and there are no assurances that we will be successful in our efforts to maintain a sufficient cash balance, report profitable operations in the future or pay our debts as they fall due, any of which could impact our ability to continue as a going concern. Any such inability to continue as a going concern may result in our shareholders losing their entire investment.

Our ability to collect for the services we provide is dependent on the financial condition of our customers, especially that of our public sector customers. The inability of our customers to pay in a timely manner or at all could result in increased working capital requirements and could have a material adverse effect on our business, results of operations and financial condition.

Our ability to collect amounts due pursuant to the terms of the contracts that we have entered into with our customers is largely dependent upon the financial condition of these customers. A significant portion of our customers are municipal entities, which are particularly sensitive to the impact of the macroeconomic and political environment, including election cycles, and, as a result, have historically demonstrated high rates of payment delinquency. As of December 31, 2017, our accounts receivable from customers totaled an aggregate R$969.8 million, 85.8% of which corresponded to accounts receivable from public sector customers, while our provisions for doubtful accounts from customers totaled R$157.2 million as of the same date, 82.9% of which corresponded to provisions for doubtful accounts from public sector customers. As of December 31, 2018, our accounts receivable from customers totaled an aggregate R$765.3 million, 87.0% of which corresponded to accounts receivable from public sector customers, while our provisions for doubtful accounts from customers totaled R$109.9 million as of the same date, 43.5% of which corresponding to provisions for doubtful accounts from public sector customers.

Brazil entered into a recession in 2014 and continues to face macroeconomic challenges (see “—Risks Related to Brazil”). We have observed that challenging macroeconomic circumstances generally impact many of our customers, particularly our municipal customers. Due to negative macroeconomic conditions, many municipalities in Brazil have suffered significant financial difficulties, reduced tax revenues, decreased federal funding and increased cost structures, all of which have imposed material budgetary constraints and cash shortfalls. Governmental entities and municipalities allocate significant portions of their budgets to waste management services costs, according to the Brazilian Ministry of Cities, so their likelihood of material delays in the payment of accounts receivable under existing contracts are exacerbated in an adverse macroeconomic scenario with increased budgetary pressures. As a result of these factors, we continue to experience increased payment delays of our public sector customers in line with delays experienced by the industry as a whole. Overall, the balance of accounts payable by Brazilian municipalities with waste management companies in Brazil has reached approximately R$11.6 billion as of December 31, 2017 according toSelur-SP (Sindicato das Empresas de Limpeza Urbana do Estado de São Paulo).

Pursuant to Brazilian law, public services may be suspended in the event the payment for past services is past due for more than 90 days, unless the suspension could result in severe disturbances of the public order. Certain of our public entity customers might argue that the suspension of our services thereunder might result in a severe disturbance of the public order, forcing us to provide such services even in the event of contractual breaches, including failure to honor payment obligations. In addition, although Brazilian law does not permit public entities to declare bankruptcy and forfeit on their obligations, it nevertheless provides them with certain extraordinary rights under distressed circumstances that provides public entities with flexibility in honoring their contractual commitments. Although such rights are subject to certain limitations, some of our public entity customers have in the past resorted to such mechanisms, resulting in payment delays and/or the renegotiation of the schedule of payments of our accounts receivable, and we expect such practices to continue in the future under certain circumstances. See “Item 5.A. Operating Financial Review and Prospects—Key Factors Affecting Our Results of Operations—How We Generate Revenue—Summary of Our Trade Accounts Receivable Policy.”

Our private sector C&I customers are also negatively affected by market forces and adverse financial and economic conditions beyond our or their control, which may result in increased delinquency or cause customers to terminate or not to renew their contracts with us. In particular, our operations serve clients in the Brazilian oil and gas, civil construction and industrial sectors, and these sectors have been acutely impacted by the ongoing Lava Jato corruption investigations in Brazil (see “—Risks Related to Brazil”).

The inability of our customers, both public and private, to pay us in a timely manner or, in the case of C&I customers, to pay the contracted rates, could have a material adverse effect on our business, results of operations, liquidity and financial condition. In addition, we may incur increased litigation expenses in our attempt to recoverpast-due amounts due to us from our customers, which may materially adversely affect our margins and results of operations.

We may not be successful in obtaining or renewing the necessary licenses to operate new landfills or expand existing ones. Further, the cost of operation and/or future construction of our existing landfills may become economically unfeasible, causing us to abandon or cease such operations.

As of December 31, 2018, we operated 12 active landfills and are in the process of developing another three greenfield landfill projects in Brazil. In Brazil, the operation of landfills is subject to various licensing requirements at the municipal, state and federal level, which specific requirements vary from location to location as well as across the regulatory spectrum, depending in part on the particular characteristics, size, location, and potential environmental impacts of each landfill. The licensing process generally comprises three phases: (i) preliminary licensing, whereby initial discussions with the pertinent environmental agencies are held, the basic conditions and milestones for the project are demonstrated and analyzed, such as its location, concept and environmental feasibility, and the basic requirements to be met during subsequent implementation phases are established; (ii) installation licensing, whereby we demonstrate our compliance with all technical specifications, terms and conditions established for the project during the preliminary licensing phase based on the approved project plans, programs and designs, including environmental control measures, and thus authorizes the implementation of the project and commencement of construction which culminates in a final review by the relevant environmental agency before the project becomes operational, and (iii) operating licensing, whereby, after implementing the project in accordance with all previously established requirements and undergoing a final review, which the operation of the project is authorized in compliance with the technical conditions set forth therein, including any environmental control measures and operating conditions. For more information, see “Item 4.B. Information on the Company—Business Overview—Licensing Regulations for Landfills.” Any delays or denials by the environmental licensing authority in issuing or renewing licenses, as well as the inability to meet the requirements established by the environmental authorities during the environmental licensing process, may delay or even prevent the construction, development and regular maintenance of our landfills, transfer stations and greenfield projects.

Our current strategic focus involves the expansion of our landfill business and, therefore, our ability to meet our business objectives depends significantly on our ability to acquire or renew landfill licenses to expand existing landfills and develop new landfill sites. The process of obtaining or renewing the required licensing to build, operate and expand solid waste management facilities, including landfills and transfer stations, can involve substantial costs over a multi-year period and is subject to a high degree of uncertainty, frequently involving factors outside of our control. Licenses to operate a landfill must be renewed numerous times during the useful life of a landfill (typically, every two to five years) pursuant to a process that requires compliance with zoning, environmental and other requirements, and may be challenged by the Public Prosecutor’s Office, special interest groups and other stakeholders. Such challenges may result in the denial of a license’s issuance or renewal, or its suspension for a shorter duration than we may have originally anticipated, or the imposition of burdensome terms and conditions that may not be favorable to us, each of which could adversely affect our business, results of operations and financial condition. Moreover, the difficulty, time and expense in obtaining and complying with licensing requirements may prevent us from taking advantage of profitable opportunities or reacting to changing market dynamics, which could adversely affect us.

After we acquire the land on which we intend to build a landfill, the process of obtaining an operating license is generally expected to take between three and five years, and, in case we are unable to secure the necessary licensing to operate the landfill in accordance with our expectations, we may elect to abandon our development plans and incur a loss in connection with a particular landfill, as has happened in the past in the case of our previous Arapiraca and Cabrália landfill projects. Such occurrence would be highly disruptive to our business plan and, due in part to the upfront costs involved in developing a landfill, could cause a material and adverse effect on our business, results of operations and financial condition.

In addition, our operating licenses must be renewed periodically. Accordingly, as a result of this renewal process, it is possible that the operation or expansion of existing landfills may become economically unfeasible based on management’s assessment of licensing issues, acceptable waste streams, available volumes and operating costs, in which case we may abandon expansion plans or abandon or cease operations entirely at a particular landfill. Any such decision could result in impairment charges as well as ongoing costs for closure and site remediation, which would adversely impact us.

Our reserves and provisions for our landfill site closure and post-closure costs and contamination-related costs may be inadequate.

We are required to pay capping, closure and post-closure maintenance costs for all of our landfill sites. Our obligations to pay closure or post-closure costs or other contamination-related costs may exceed the amount we have accrued and reserved and other amounts available from funds or reserves established to pay such costs. We estimate capping, closure and post-closure maintenance costs and establishes reserves considering the type of landfill, volumetric capacity and the density of the waste to be disposed at a particular site. Any defect or failure in judgment in connection with such assumptions could lead to substantially higher costs than anticipated.

In addition, according to Brazilian regulations, subsequent to the closure of a landfill site, we must continue to monitor and maintain the underground and surface water, leachate treatment, gas collection system, drainages and capping of closed landfills for so long as the closed site is no longer potentially harmful to the environment or the community. In order to satisfy such obligation, we are required to, among other measures, calculate and provision the expected costs associated with such activities, taking into account the particular conditions, the characteristics of each landfill site and the planned future uses of the site, as well as the expected costs of securing the perimeter of such landfill sites and maintaining the necessaryon-site structures. We cannot assure you that we will have established sufficient reserves for all potential liabilities in connection with our landfill closure activities, and we may become liable for unforeseen environmental issues that could result in payment of substantial costs that may not have been fully provisioned, such as remediation costs, that could adversely affect our financial condition or operating results. See “Item 5.A. Operating and Financial Review and Prospects—Operating Results—Critical Accounting Policies—Landfill accounting and provision for landfill closure.”

The Brazilian waste management industry is fragmented and characterized by a high degree of competition.

The Brazilian waste management industry is highly fragmented, with no single player accounting for more than 15.0% of market share, and the top five largest players collectively accounting for 42.4% in 2017, according to the most recent ABRELPE data in conjunction with our internal studies. This high degree of fragmentation corresponds to an exceedingly competitive environment requiring substantial labor and capital resources to maintain and capture business. Some of the markets in which we compete or plan to compete are served by one or more large companies, as well as by regional and local companies of varying sizes and resources, some of which may have accumulated substantial goodwill in their markets.

Some of our competitors may be better capitalized in comparison, benefitting, in some cases, from the infrastructure and financial backing of international platforms, while other competitors may have greater name recognition than us, or be able to provide or be willing to bid their services at a lower price than we may be willing or able to offer. We may also face competition from companies that possess more specialized, technical expertise in certain niche services or markets.

We also compete with counties, municipalities and solid waste districts that maintain or could in the future choose to carry out and maintain their own waste collection and disposal operations. These operators may have financial advantages over us because of their access to user fees and similar charges, tax revenues,tax-exempt financing or government subsidies.

An increase in these or other competitive pressures, or our inability to compete effectively, could hinder our growth or adversely impact our business, results of operations and financial condition.

Our business requires a high level of capital expenditures.

Our business is capital-intensive. We must use a substantial portion of our cash flows from operating activities toward capital expenditures, which reduces our flexibility to use such cash flows for other purposes, such as reducing indebtedness. For example, pursuant to certain services contracts we are required to devote significant capital amounts to invest in the renewal of our vehicle fleet, the failure of which could result in the breach of certain obligations under the applicable contract and potentially lead to a suspension, or early termination, of such contracts. We are also required to invest significant capital in the opening and development of new landfill cells, the failure of which could result in damage to our landfill operations and ability to continue to receive hazardous and nonhazardous waste. Our capital expenditures could increase if we make acquisitions or further expand our operations or as a result of factors beyond our control, such as changes in federal, state, local or international requirements. The amount that we spend on capital expenditures may exceed current expectations, which may require us to obtain additional funding for our operations thereby adding additional stress on our liquidity position and adversely affecting us.

The waste management industry is characterized by increasing technological innovation, and our success depends on our capacity to enhance and maximize our existing services and develop new services.

We and others in the industry are increasingly focusing on new technologies that provide alternatives to traditional disposal and maximize the resource value of waste. If we fail to develop or adapt our services on a timely and cost-efficient basis to address customer needs in an evolving technological environment or to respond to regulatory or legislative changes, our competitiveness will be negatively impacted and our customer retention may suffer. We may experience difficulties or delays in the research, development, production or marketing of new services, which may negatively impact or operating results and prevent us from recouping or realizing a return on the investments required to bring new services to market. In particular, if a competitor develops or obtains exclusive rights to a breakthrough technology that provides a revolutionary change in traditional waste management, our financial results may suffer.

The renegotiation of collective bargaining agreements with the labor unions representing our employees may result in increased costs and other disruptions to our business.

Our employees are represented by labor unions with a strong presence in the waste management market. We have entered into collective bargaining and other agreements with each of these unions through a special committee, which agreements define, among other matters, the length of the work day, minimum compensation, vacations and other ancillary benefits for our employees. We renegotiate these agreements on an annual basis and, historically, have significantly adjusted the terms of these agreements upon renegotiation. When we renegotiate wage and salary adjustments, including the establishment of minimum wage thresholds, we typically use the inflation rate as a reference. Our personnel costs may increase significantly as a result of our renegotiation of collective bargaining agreements, which represents a major part of our cost of services. Our business and results of operations may be materially adversely affected if we are not able to pass the increased costs arising from the renegotiation of collective bargaining agreements onto our customers through inflation-based price increases. In addition, we may be negatively impacted if we otherwise fail to maintain harmonious relationships with the labor unions representing our employees, which could lead to strikes, work stoppages or other labor disruptions by its employees. Depending on the type and duration of any labor disruptions, our operating expenses could increase significantly, which could adversely affect our financial condition, results of operations and cash flows.

Increases in labor costs could impact our financial results.

Labor is one of our highest costs and relatively small increases in labor costs per employee could materially affect our cost structure. Our continued success will depend on our ability to attract and retain qualified personnel. A shortage of qualified employees, such as truck drivers or mechanics, would require us to enhance our wage and benefits packages to compete more effectively for employees, to hire more expensive temporary employees or to contract for services with more expensive third-party vendors. If we fail to attract and retain qualified employees, control our labor costs during periods of declining volumes or recover any increased labor costs through increased prices we charge for our services or otherwise offset such increases with cost savings in other areas, our operating margins could suffer.

We depend significantly on the services of the members of our senior, regional and local management teams, including our current CEO and the departure of any of those persons or the inability to adequately replace any such manager could cause our operating results to suffer.

Our success depends significantly on the continued individual and collective contributions of our senior, regional and local management teams including our current CEO. The loss of the services of any member of our senior, regional or local management, in particular our CEO, Mr. Pedreiro, or the inability to hire and retain experienced management personnel could have a material adverse effect on us. Our currently distressed financial situation has further increased the risk of the departure of one or more senior managers and the inability to adequately replace any such manager in the event of a departure.

We may be held legally responsible for the acts and omissions of outsourced personnel.

We rely on outsourced personnel to carry out certain of ournon-strategic functions (such as landfill security and gatekeepers) and to ensure the proper functioning of our operations in satisfaction of client needs at a lower cost. If the outsourcing companies engaged by us fail to comply with applicable labor laws in relation to their employees sent to provide services on our behalf, we, as a matter of Brazilian labor law, may be held severally liable for such violations over which we have little to no authority to monitor or prevent. As a result, we may be subject to fines and other penalties imposed by the relevant labor authorities or courts. If we are held liable for labor claims in connection with our outsourced personnel, our business and results of operations may be negatively impacted.

Increases in insurance costs and the amount that we self-insure for various risks could reduce our operating margins and reported earnings.

Our business exposes us to the risk of liabilities arising out of our operations, including environmental and labor-related claims as well as claims for personal injury, death and property damage resulting from the use of the trucks, machinery and equipment used in our operations. We maintain insurance policies at amounts considered by our management to be sufficient to cover possible losses, considering the nature of our activities and our size and operations. Our insurance policies cover: (i) environmental damage, (ii) civil liability, (iii) damage to property, including fleet and equipment, (iv) pain and suffering, (v) fire, lightning and explosion and (vi) directors’ and officers’ insurance. Our coverage limits might not be sufficient to cover all potential losses. We cannot assure you that we will not be exposed to uninsured liability at levels in excess of our historical levels resulting from multiple payouts or otherwise or that liabilities in respect of existing or future claims will not exceed the level of our insurance. Losses that exceed the insured amount or that are not covered by our insurance could result in material additional and unexpected costs. These could affect our results of operations and financial condition. For additional information regarding our insurance coverage, see “Item 4.B. Information on the Company—Business Overview—Insurance.”

We are party to various judicial, administrative, tax or other third-party proceedings that could interrupt or materially limit our operations, result in adverse judgments, settlements or fines and create negative publicity.

We are, and in the future may be, a defendant in various judicial, arbitral and administrative proceedings arising in the ordinary course of our business and also, on an exceptional basis. Such disputes may relate to civil, tax, labor or environmental matters and involve our suppliers, customers, management or environmental and tax authorities, among others. In addition, particularly in relation to our landfill operations, the Public Prosecutor’s Office, as well as individuals, citizens groups, trade associations, community groups or environmental activists, may bring actions against us in connection with our operations that could interrupt or limit the scope of our business. Many of these matters raise difficult and complicated factual and legal issues and are subject to uncertainties and complexities. The timing of the final resolutions to lawsuits, regulatory inquiries, and governmental and other legal proceedings is uncertain. Additionally, the possible outcomes or resolutions to these matters could include materially adverse judgments or settlements, either of which could require substantial payments or other significant financial obligations. We cannot assure you that the outcomes of these proceedings will be favorable to us, or that we will have established sufficient reserves for all potential liabilities in connection with these proceedings.

Unfavorable decisions or settlements in relation to these proceedings that prevent us from conducting our business as initially planned, or that involve substantial amounts that have not been adequately provisioned, may materially adversely affect our business, financial condition and results of operations. For example, based on advice of our external legal counsel, who assessed the risk of a potential loss as possible (and not probable), we have not recorded provisions in the aggregate amount of R$120.9 million and R$212.4 million in relation to recent tax assessments that we received from BFRS at the end of 2018 and 2017, respectively. Therefore, in the event that such possible loss materializes, our provisions would not be sufficient to cover our contingencies in relation to this liability. For more information on the material proceedings to which we are a party, see “Item 8.A. Financial Information—Consolidated Statements and Other Financial Information—Legal and Administrative Proceedings and Investigations.”

Changes in the tax regimes to which we and our customers are subject may adversely affect us. Brazilian tax authorities may challenge the tax treatment given to certain of our transactions, potentially resulting in significant tax liabilities that could adversely affect us.

The Brazilian government frequently implements changes to tax regimes that may affect our customers and us. These amendments may include changes in prevailing tax rates and, occasionally, the implementation of temporary taxes, the proceeds of which are earmarked for designated governmental purposes. Some of these changes may result in increases in our tax obligations and payments, which could cause us to increase the prices of our services, restrict our ability to do business in our existing and target markets and adversely affect our financial condition and results of operations. There can be no assurance that we will be able to maintain our projected cash flow and profitability following any increases in Brazilian taxes applicable to us and our operations.

Our income tax expense, deferred tax assets and liabilities and reserves for unrecognized tax benefits reflect management’s best assessment of estimated future taxes to be paid, which requires a significant degree of judgment and estimates. We cannot assure you that Brazilian tax authorities will agree with the assessments made with respect to our tax liability. Under Brazilian law, the tax authorities may challenge the amount of taxes we have paid for a period of up to five years counted from the taxable event or the first day of the following year, based on a variety of factors, including the nature of the tax payable and whether it involves self-reporting by the taxpayer orpre-payment as well as the existence of fraud. Any such challenges may require us to devote additional resources to defend the tax treatment we have ascribed to such transactions and, if adjudicated and decided against us, may result in the incurrence of significant tax liabilities, including fines and other capital commitments, and may have a negative impact on our public image, each of which could adversely affect us.

Moreover, the tax treatment for certain categories of transactions are more vulnerable to challenges by the Brazilian tax authorities. For example, we regularly perform intercompany transactions (such as loans and other financial or operational transactions), the tax treatment of which is especially uncertain under Brazil’s regulatory framework, and is more likely to be questioned by Brazilian tax authorities, particularly with respect to their compliance with IOF or IRRF tax rules.

In addition, ournon-compliance with any ancillary obligations could also result in further questioning by the tax authorities and result in additional tax liabilities, including fines and other capital commitments, which could adversely affect us.

We may be liable in connection with discontinued operations over which we currently have no control.

As part of our restructuring effort and with the objective of streamlining our operations and increasing our margins, we have divested of several assets in recent years, including our operations outside of Brazil and a significant portion of our oil and gas activities. For additional information, see “Item 4.A. Information on the Company—History and Development of the Company—Recent Divestments and Acquisitions.” Under Brazilian law, we may be subject to liability, financial losses, and adverse impacts on our image and reputation resulting from past divestitures, particularly in the event that the new owner of our divested assets is found to have insufficient funds to perform on our obligations with respect to those assets.

For example, in January 2016, we entered into an agreement with USA Global MKT (“USA Global”), for the sale of our 51% interest in Doña Juana S.A. ESP (“Doña Juana”), based in Colombia. Pursuant to the terms of the agreement, USA Global, our partner andco-investor in Doña Juana, agreed to seek out a compatible buyer for our interest in Doña Juana and, in the meantime, advanced payments to us for the sale. Following the execution of the agency agreement with USA Global, our results of operations from Doña Juana were recorded as discontinued in 2016, and we ceased to have any participation in the management and affairs of Doña Juana. On November 20, 2018, we fully transferred our shares in Doña Juana to Ecensa Colombia S.A.S. (“Ecensa Colombia”), a subsidiary of USA Global, but continue to have an outstanding balance of receivables in the amount of US$0.8 million (R$2.8 million, calculated using the average FX rate from January 1 to November 30, 2018) as of December 31, 2018 that is payable by USA Global. As a landfill, Doña Juana’s operations are inherently susceptible to various risks, including, among others, in connection with landfill site closure and post-closure costs as well as contamination-related costs. Our potential liability could be significant to the extent these risks materialize, particularly in relation to activities occurring during the period when we still had control. However, despite our sale and transfer, we may continue to be liable for the activities at Doña Juana during times at which we had no authority or control of the entity.

Another example relates to our sale of Estre Óleo e Gás Holding S.A. (“Estre O&G”) in 2014, following which we continued to have contractual obligations to provide certain services to Estre O&G’s business partners through 2017. In addition, we are the subject of, or mentioned in the context of, certain allegations and investigations of misconduct in connection with our discontinued operations. For further information, see “—Risks Related to Compliance and Control” below and “Item 5.A. Operating and Financial Review and Prospects—Operating Results—Discontinued Operations.” Given the current stage of the investigations, we cannot predict whether any such investigations will proceed and, if so, the duration or ultimate outcome of the investigation. In the event we are charged with any violations on the basis of the investigations or other investigations related to discontinued operations or otherwise held responsible in relation thereto, we may be subject to substantial monetary fines and potential ineligibility from contracting with state owned or government entities, which could also have significant impact on our results of operations.

We could also be liable for latent civil, tax, environmental, criminal and labor claims arising out of causes or circumstances existing during the time which we owned the assets we have since divested, the occurrence of which could have an adverse effect on us. For example, in the event that we are deemed responsible for causing an environment damage on a divested asset (irrespective of whether the former operations were supported by environmental licenses or not), we will nevertheless be held liable for the full extent of the damages, including the responsibility for repairing such damage in accordance with applicable legislation, to which statutes of limitations may not apply. Environmental liability may be also be attributed by administrative and criminal courts by imposing administrative and criminal sanctions uponnon-compliance with law. Administrative sanction can only be imposed within five years from the violation of the applicable violation and the statute of limitations of criminal liability varies according to the penalty imposed for the committed misconduct. Under Brazilian environmental laws and regulations, companies are subject to strict liability for damages caused to the environment, and no statute of limitations applies.

Any adverse outcome resulting from such risks or liabilities could harm our business, results of operations and financial condition and could create negative publicity that may be damaging to our reputation and competitive position.

Current and future accounting pronouncements and other financial reporting standards, including, but not limited to, those concerning revenue recognition, will impact our financial results.

The IASB, or other regulatory bodies, periodically introduce modifications to financial accounting and reporting standards under which we prepare our audited financial statements. A number of new accounting standards and amendments and interpretations to existing standards have recently been issued, including IFRS 15 regarding revenues from contracts with customers and IFRS 9 regarding financial instruments We have adopted these new accounting standards on the effective date required, which was January 1, 2018 and, therefore, the audited financial statements included in this annual report reflect the application of these new accounting standards.

Upon application of IFRS 9, we recorded a R$3.5 million decrease in the allowance for doubtful accounts on January 1, 2018. The adoption of IFRS 15 resulted in an impact of R$2.3 million, net of deferred income tax and social contribution of 34%, which was recorded in shareholders’ equity as of January 1, 2018.

In addition, on January 1, 2019, we adopted IFRS 16 which establishes principles for the recognition, measurement, presentation and disclosure of leases and requires lessees to account for all leases under a singleon-balance sheet model similar to the accounting for finance leases under IAS 17. On January 1, 2019, we recognized aright-of-use asset and a lease liability of R$23.3 million.

For further information regarding the new standards effective as of January 1, 2018 and new accounting requirements, including IFRS 16 – Leases, see “Item 5.A. Operating and Financial Review and Prospects—Operating Results—New Accounting Standards Issued But Not Implemented” and notes 2.22 and 2.23 to our audited financial statements included elsewhere in this annual report.

We rely on a limited number of suppliers for our heavy vehicles, which may materially adversely affect our ability to acquire a waste collection fleet on favorable terms.

In Brazil, the collection and transfer trucks that comprise our fleet are manufactured and sold by only a few suppliers, with Volkswagen, MAN, Mercedes Benz and Ford dominating the market. Accordingly, in the event our suppliers decide to unfavorably modify the purchasing terms for these vehicles, our flexibility to acquire these vehicles elsewhere is limited. As a result, our ability to renew and expand our fleet may be negatively affected and, consequently, our ability to effectively serve customers could suffer.

Risks Related to Compliance and Control

We have been charged, and remain under investigation by, the Brazilian tax authorities, alleging unpaid taxes over the course of several years arising from understated income due to alleged improper payments to certain suppliers. These charges, as well as potential future tax infringement charges, could result in substantial fines, penalties and criminal and regulatory sanctions, among other adverse effects.

Since 2015, the BFRS has periodically filed Notices of Tax Enforcement addressed to us, requiring that we produce information concerning transactions with a number of specified suppliers in relation to payments made from 2010 to 2015. In the majority of cases, these requests for information have resulted in official tax infringement notices charging our failure to pay the full amount of federal taxes due for a specified period on the assumption that we understated our taxable income for such periods due to costs recorded from alleged improper payments to certain suppliers. These tax infringement notices subject us to significant tax liabilities, including fines established by the BFRS and payments of interest. The statute of limitations for these claims is five years.

In 2017, we were able to settle certain tax liabilities resulting from these tax infringement charges on attractive terms through tax amnesty programs offered for a limited time in Brazil. However, after these amnesty programs were closed, (i) on December 15, 2017, Cavo Serviços e Saneamento S.A. (“Cavo”), the entity through which we hold an equity stake in Soma, received an official tax infringement notice from the BFRS in the amount of R$90.6 million concerning transactions with a number of specified suppliers in relation to payments made in 2012, (ii) on December 22 and 27, 2017, the Company received two additional official tax infringement notices from the Brazilian federal tax authorities in the aggregate amount of R$121.8 million concerning transactions with a number of specified suppliers in relation to payments made in 2012, (iii) on December 4, 2018, the Company received a further tax infringement notice from the Brazilian federal tax authorities in the aggregate amount of R$53.5 million concerning transactions with a number of specified suppliers in relation to payments made in 2013, and (iv) on December 11, 2018, Cavo received an additional tax infringement notice from the Brazilian federal tax authorities in the total amount of R$65.6 million relating to transactions entered into with a number of specified suppliers and related payments made in 2013. There is no guarantee that additional tax amnesty programs will be offered by the Brazilian government on favorable terms, or at all. We have not established provisions related to these matters based on the advice of our independent Brazilian counsel. For further information regarding our tax proceedings, see “Item 8.A. Financial Information—Consolidated Statements and Other Financial Information—Legal and Administrative Proceedings and Investigations.”

For the reasons described above, the current tax charges against us, as well as potential additional tax charges that we may receive in the future, may expose us to significant fines, penalties, judgments, damages and/or settlements as a result ofnon-compliance with applicable legal and regulatory requirements in amounts that exceed the provisions we have established in relation to these tax contingencies (see “Item 8.A. Financial Information—Consolidated Statements and Other Financial Information—Legal and Administrative Proceedings and Investigations”).

Furthermore, we have reason to believe that the tax authorities have shared their findings with other Brazilian authorities, including theLava Jato investigators. For example, the Brazilian federal police’s search of our corporate offices and the premises of Soma on March 1, 2018 as part of theso-called OperationDescarte was a collective effort in cooperation with the Brazilian tax authorities within the ambit of the broaderLava Jato task force. Accordingly, any tax charge from the BFRS could potentially result in additional regulatory and criminal inquiries, charges and, eventually, sanctions. Any such consequences emanating from these tax charges could significantly impact our results of operations, cash flows, ability to execute our growth strategy and overall financial health.

Based on our historical experience, we may receive additional tax infringement charges in the future in relation to other suppliers, facts or periods, particularly as the statute of limitations related to such matters approaches expiration. Any of these tax infringement charges may involve additional criminal and regulatory actions and governmental inquiries that could have a material adverse effect on us and otherwise severely limit our business.

Investigations by governmental authorities under the applicable anti-corruption and money laundering laws, including the currently ongoing Operation Descarte, may result in substantial fines, ineligibility from contracting with state-owned or government entities, criminal action against our management team and other adverse effects.

We, the former chairman of the Company’s board of directors as well as businesses formerly owned by us are currently the subject of, or otherwise implicated in, certain allegations and investigations of misconduct in relation to alleged improper payments. For further information regarding the related facts, see “Item 8.A. Financial Information—Consolidated Statements and Other Financial Information—Legal and Administrative Proceedings and Investigations.”

On March 1, 2018, the Brazilian Federal Police executed search warrants at a number of companies in the cities of São Paulo, Santos, Paulínia, Belo Horizonte and Lamim, including at the premises of Soma as well as the Company’s corporate offices and at Paulínia landfill. This action was part of theso-calledOperation Descarteeffort of the Brazilian Federal Police working in conjunction with the Brazilian tax authorities within the ambit of the broaderLava Jatotask force, with the stated objective of dismantling a criminal money-laundering network. As part of their search of our corporate offices, the Brazilian Federal Police confiscated numerous hard copy and electronic files related to specified suppliers, among other materials.

Most recently, on January 31, 2019, the Brazilian federal police executed search warrants at various locations in the State of São Paulo, including at the Company’s corporate headquarters, as part of investigations related to contracts entered into in the period between 2008 and 2014 between Estre and some of its former subsidiaries and Petrobras Transporte S.A. – Transpetro (“Transpetro”), a subsidiary of the Brazilian company Petroleo Brasileiro S.A. – Petrobras. We understand that the police investigation was launched within the gambit of the broaderLava Jato investigation and as a result of a plea bargain agreement entered into by Mr. Sergio Machado, the former president of Transpetro. As part of this police operation, temporary arrest warrants were also executed leading to, among others, the arrest of the founder and former chairman of Estre, Mr. Wilson Quintella, and a former senior employee of the Company, Mr. Antonio Kanji Hoshikawa.

On February 1, 2019, Mr. Quintella appeared for a deposition before the Brazilian federal police and confessed both to making payments to Mr. Sergio Machado and to the involvement of Mr. Kanji in executing such payments. On March 1, 2019, the federal prosecutor’s office filed a criminal complaint against Mr. Quintella and other former senior employee of the Company, whereby the prosecutors presented an indicative amount of at least R$79.6 million to be claimed from the individuals in connection with the alleged wrongdoing. In the future, similar claims could be made on civil compensation grounds against the Company.

We cannot predict whether these criminal investigations will move forward and, if so, the duration, scope or ultimate outcome of these investigations. The criminal proceedings are still ongoing and new facts may emerge. In the event we are charged with any violations on the basis of the investigations, these charges may seek to impose various sanctions, including significant monetary fines, potential ineligibility from contracting with state-owned or government entities, injunctions against future conduct, profit disgorgements, disqualifications from directly or indirectly engaging in certain types of businesses, the loss of business permits or other restrictions which could have a material adverse effect on our business, financial condition, results of operations or liquidity. An announcement of a negative outcome of an investigation, or the bringing of any charges against us (or persons or entities affiliated or previously affiliated with us), could also expose us to civil suits or regulatory action, and/or damage our reputation. The materialization of any of these events could have a material adverse effect on us.

Our governance, risk management, compliance, audit and internal controls processes might be unable to prevent, detect or remedy behaviors that are incompatible with relevant legal requirements or our own ethical or compliance standards, which could in turn expose us to sanctions, regulatory penalties, civil claims, tax claims, damage to our reputation, accounting adjustments or other adverse effects.

In 2015, under the leadership and guidance of our current CEO, Mr. Sergio Pedreiro, and in response to Brazil’s new anticorruption law adopted in 2014 and an intensified focus in Brazil on the prevention of corrupt practices, we implemented a new compliance program focused on transparency and ethical conduct. Since 2015, we have invested significantly in our internal controls mechanisms with the objective of auditing, detecting and reporting irregularities, imposing disciplinary measures and taking remedial or punitive measures in the case of violations. We have a focused commitment to continuing to strengthen our compliance policies and internal control systems.

Nevertheless, despite these substantial efforts, we have identified certain shortcomings and defects of our compliance infrastructure as a result of the Internal Evaluation Process (see “Item 15. Controls and Procedures”), particularly in relation to the implementation of our compliance program at Soma. Accordingly, we cannot assure you that our governance, risk management, compliance, audit and internal controls processes will be able to prevent, detect or remedy all behaviors that are incompatible with the applicable legal requirements or our own ethical or compliance standards, and any weakness or breach could expose us to sanctions, regulatory penalties, civil claims, tax claims, monetary losses, accounting errors or adjustments, reputational damages, or other adverse effects.

We are subject to the risk that our employees, counterparties or any person doing business with us may engage in fraudulent activity, corruption or bribery, circumvent or override our internal controls and procedures or misappropriate or manipulate our assets for their personal or business advantage. In the event that we believe or have reason to believe that our employees or agents have or may have violated applicable anti-corruption laws, including the U.S. Foreign Corrupt Practices Act (the “FCPA”), the Brazilian Anti-Corruption Law and similar anti-corruption laws, we may be required to investigate or have outside counsel investigate the relevant facts and circumstances, which can be expensive and require significant time and attention from senior management.

It is difficult for us to ensure that all of our employees and contractors will comply with and uphold our ethical principles, a risk that we believe we are highly susceptible to given the nature of our business in Brazil and substantial commercial dealings with municipal entities. Any weakness or breach in our governance, risk management, compliance, audit and internal controls processes could expose us to sanctions, regulatory penalties, civil claims, tax claims, monetary losses, accounting errors or adjustments, reputational damages, or other adverse effects. The perception or allegations that we, our employees, our affiliates or other persons or entities associated with us have engaged in any such improper conduct, even if unsubstantiated, may cause significant reputational harm and other adverse effects.

We have conducted several internal reviews related to our supply relationships, and additional facts and circumstances could arise requiring further evaluation.

As part of our response to ongoing investigations by the Brazilian authorities into potential misconduct, we have periodically engaged external consultants to review documentation concerning transactions with our suppliers.

Following a review of our transactions with specified suppliers in 2017, forensic consultants determined that certain disbursements made by us to contractors, suppliers and other service providers could not be properly supported by the documentary evidence. As a result of these findings, we terminated our commercial arrangements with a number of suppliers andwrote-off certain items of property, plant and equipment on our balance sheets for which proper support for payments was not available and their existence could not be properly verified. See “Item 5.A. Operating and Financial Review and Prospects—OperatingResults—Write-off of Property, Plant and Equipment.”

Following the receipt of tax infringement notices at the conclusion of 2017 (see “Item 8.A. Financial Information—Consolidated Statements and Other Financial Information—Legal and Administrative Proceedings and Investigations”), we engaged a forensic services firm to review Soma’s relationships with certain suppliers. This investigation was only in the preliminary stages when the Brazilian federal police searched our corporate offices and the premises of Soma on March 1, 2018. In the aftermath of the events of March 1, 2018, we broadened the scope of the internal review process at the direction of a newly constituted special committee of our board of directors comprised of independent members of our board of directors. This expanded internal evaluation process sought to ascertain the nature of the goods and services provided to us for payments made to certain suppliers during the period from 2012 to 2017, including via Soma and our joint ventures. As a result, we identified payments to certain suppliers, particularly through Soma, for which there was insufficient evidence that goods and services were provided. Considering these findings, we restated our financial statements as of January 1 and December 31, 2016 and for the years ended December 31, 2015 and 2016, as presented and restated in the 2017 annual report and recalculated our income tax payable corresponding to our management’s assessment of probable tax losses emanating from these payments, as further described under “Item 5.A. Operating and Financial Review and Prospects—Operating Results—Internal Evaluation Process and Previous Restatement of Financial Statements,” “Item 8.A. Financial Information—Consolidated Statements and Other Financial Information—Legal and Administrative Proceedings and Investigations” and Note 1.4 of our audited financial statements included herein.

Internal evaluation processes are costly and disruptive and require significant time, resources and management attention. They are also subject to inherent shortcomings, namely involving (i) the absence of subpoena power to compel production of relevant documents from third parties, and (ii) the inability to compel interviews with important witnesses, such as certain former members of our management team. Accordingly, it is possible that improper conduct may have occurred within the Company that was not captured or considered in the Internal Evaluation Process and other historical investigations. As result, it is possible that facts and circumstances could arise in the future related to alleged improper conduct that we have not considered or adequately prepared for but could nevertheless expose us to significant liability, warrant further investigation, or involve further restatement of our audited financial statements.

Allegations and investigations of impropriety involving Wilson Quintella Filho, our founder, a shareholder and former chairman of our board of directors, have surfaced as part of Brazil’s ongoing Lava Jato and Operation Descarte investigations, which have, and may continue to, adversely affect us, principally by harm to our reputation. Any negative developments in or relating to such allegations and investigations involving Mr. Quintella could further adversely affect us.

There are several allegations of improper payments and other improper conduct against Mr. Quintella, who is our founder, a minority shareholder and former chairman of our board of directors, and certain entities affiliated with him, in connection with the ongoingLava Jato investigation, including entities that were previously under our control. In 2018, Mr. Quintella’s personal apartment was subject to a police search as part of OperationDescarte, and on February 1, 2019, Mr. Quintella appeared for a deposition before the Brazilian federal police and confessed both to making payments to Mr. Sergio Machado and to the involvement of Mr. Kanji, a former employee of the Company, in executing such payments. On March 1, 2019, the federal prosecutor’s office filed a criminal complaint against Mr. Quintella and other former senior employee of the Company, whereby the prosecutors presented an indicative amount of at least R$79.6 million to be claimed from the individuals in connection with the alleged wrongdoing In the future, similar claims could be made on civil compensation grounds against the Company. For further information regarding the related facts, see “Item 8.A. Financial Information— Consolidated Statements and Other Financial Information—Legal and Administrative Proceedings and Investigations.”

Although Mr. Quintella no longer has management control over us and his share ownership in us (held through Cygnus Asset Holding Ltd) has been significantly reduced to 5.9% as a result of the Transaction, we nonetheless believe that, because of Mr. Quintella’s connections with us as our founder, shareholder and former chairman, these allegations could have adverse impacts on us, principally by way of harm to our reputation and, potentially, as a result of his ongoing influence on our employees resulting from his historical role at the Company. We cannot predict the outcome of the ongoing investigations and the criminal complaint involving Mr. Quintella or whether the authorities will ultimately prosecute us in administrative and civil court, as applicable. The criminal proceedings are still ongoing and new facts may emerge. Both the investigation and the complaint may further negatively impact our reputation or otherwise adversely affect us.

Our commercial relationship with Petrobras has been the subject of inquiry.

We had a commercial relationship with Petrobras and certain of its 2016, 2017 and 2018 generated total revenues of R$52.5 million, R$18.5 million and R$12.8 million, respectively, from such relationship, all of which was allocated to our Oil & Gas (O&G) segment. Petrobras is the primary customer in our Oil & Gas segment, representing 83.6% of the net revenues from services rendered for this segment in 2016, 71.4% in 2017 and 100% in 2018. We engaged independent consultants to review our commercial relationships with Petrobras mainly in response to ongoing investigations by the Brazilian authorities and other allegations related to our historical relationship with Petrobras (see “Item 8.A. Financial Information—Consolidated Statements and Other Financial Information—Legal and Administrative Proceedings and Investigations.”). This review of our dealings with Petrobras was concluded in January 2018 and the consultants identified a number of suppliers that provided goods and services in connection with our Petrobras engagements. These suppliers were then included in the Internal Evaluation Process described above and the respective supply relationships were evaluated across our organization, including Soma and our joint ventures.

We, our affiliates and our shareholders could be materially affected by violations of the FCPA, the Brazilian Anti-Corruption Law and similar anti-corruption laws.

We, our subsidiaries and our joint venture partners are subject to a number of anti-corruption laws, including Law No. 12,846/2013, or the Brazilian Anti-Corruption Law, which became effective on January 28, 2014, the FCPA and various other anti-corruption and anti-bribery laws of other jurisdictions.

The FCPA, the Brazilian Anti-Corruption Law and similar anti-bribery laws in other jurisdictions generally prohibit companies and their intermediaries from making improper payments to government officials or other persons for the purpose of obtaining or retaining business. If our policies and procedures designed to prevent bribery and other corrupt practices were not in the past or are not in the future capable of preventing voluntary or inadvertent action by our administrators, employees or third parties acting on our behalf that constitutes corruption, applicable regulatory agencies, to which we respond, have the power and authority to impose fines and other penalties.

Violations of these laws, which could arise out of the current allegations and investigations involving Wilson Quintella Filho or otherwise, may result in criminal or civil sanctions (including fines), inability to do business with existing or future business partners, injunctions against future conduct, profit disgorgements, disqualifications from directly or indirectly engaging in certain types of businesses, the loss of business permits or other restrictions which could have a material adverse effect on our business, financial condition, results of operations or liquidity.

Any company that controls, is controlled by, or has a material interest in a company that violates the provisions of the Brazilian Anti-Corruption Law may be held joint and severally liable for the payment of fines and monetary damages arising from such violations. Under Brazilian law, “material interest” means that a given investor either (i) has or exercises the power to participate on decisions involving financial or operational policies of the invested company, without controlling it, or (ii) holds a 20% or higher stake in the voting capital of the invested company, without controlling it.

Personnel from BTG Pactual are the subject of investigations in Brazil, which because of the relationships between BTG Pactual and us may have an adverse impact on our reputation or otherwise.

We have various significant relationships with BTG Pactual, which remains our largest shareholder after the Transaction. Furthermore, certain members of our senior management, including the CEO, are affiliated with BTG Pactual. BTG Pactual is also the holder of 27.0% of our debentures and 52.9% of the Company’s total debt, encompassing the outstanding existing debentures and other obligations arising out of the related debt acknowledgment instrument, as amended and restated pursuant to the Debt Restructuring. In 2015, André Esteves, then the CEO and chairman of BTG Pactual, was temporarily taken into custody in Brazil in connection with allegations of obstruction of justice, which allegations were unrelated to us or BTG Pactual’s and Mr. Esteves’s relationship to us.

On September 1, 2017, the Brazilian Federal Prosecutor’s Office filed its closing arguments requesting the dismissal of all charges against Mr. Esteves. On July 12, 2018, Mr. Esteves was acquitted by the competent court of the charges and the case was officially closed on August 17, 2018. However, as a result of certain statements included in the plea bargain of Delcídio do Amaral Gomez, a former Brazilian senator, Mr. Esteves became subject to additional corruption-related investigations. Other corruption related allegations have been made against Mr. Esteves in connection with an investment by Banco BTG Pactual in assets acquired by Banco BTG Pactual from Petrobras from its PetroAfrica subsidiary as well. None of the foregoing matters have resulted in any criminal charges being brought against Mr. Esteves, BTG Pactual or any other Banco BTG Pactual employees. While a conviction of Mr. Esteves in the ongoing criminal proceedings seems unlikely given the dismissal of all charges as described above on July 12, 2018 by the court of competent jurisdiction and the official closing of the case on August 17, 2018, we cannot predict the ultimate outcome of that criminal proceeding or whether any of the investigations, including new investigations resulting from plea bargains involving third parties or otherwise, will result in criminal charges being brought against Mr. Esteves. Should Mr. Esteves be found liable for any misconduct or should BTG Pactual or any of its affiliates be accused of or found responsible for any wrongdoing, there may be negative impact on our reputation or otherwise, such as administrative or civil liability, as a result of our relationship with BTG Pactual.

We have identified weaknesses in our internal control over financial reporting and our disclosure controls and procedures.

In connection with the audit of our audited financial statements for the year ended December 31, 2018 included in this annual report, we and our independent registered public accounting firm identified material weaknesses in our internal control over financial reporting. In addition, our management has concluded that our disclosure controls and procedures as of December 31, 2018 were not effective due to such weaknesses in internal control over financial reporting. In addition, in connection with the preparation of our annual report for the year ended December 31, 2017, we also identified material weaknesses in our internal control over financial reporting, and consequently, in our disclosure controls and procedures.

Details of the material weaknesses in our internal control over financial reporting are set forth in detail under “Item 15. Controls and Procedures.”

Although our management has put in place a remediation plan aimed at addressing the material weaknesses that we have identified, we cannot at this time estimate how long it will take to fully remediate the weaknesses identified in this annual report and our efforts may not be successful in remediating these material weaknesses. In addition, we will incur additional costs in improving our internal control over financial reporting and our disclosure controls and procedures. If we are unable to remediate these material weaknesses, or if we experience additional weaknesses in the future or otherwise fail to maintain an effective system of internal controls or disclosure controls and procedures, we may not be able to accurately or timely report our financial condition or results of operations, which may adversely affect investor confidence in us and, as a result, the value of our securities.

Our independent registered public accounting firm has not performed an evaluation of our internal control over financial reporting in accordance with Section 404 of the Sarbanes-Oxley Act for purposes of identifying and reporting any weakness or significant deficiency in our internal control over financial reporting, as our independent registered public accounting firm will only be required to do once we cease to be an emerging growth company. Had our independent registered public accounting firm performed an audit of our internal control over financial reporting, additional weaknesses in our internal control over financial reporting may have been identified.

We have recently implemented new process management software and are increasingly dependent on technology in our operations and, if our technology fails, our business could be adversely affected.

We may experience problems with the operation of our current information technology systems or the technology systems of third parties on which we rely, as well as the development and deployment of new information technology systems, any of which could adversely affect, or temporarily disrupt, all or a portion of our operations until resolved. For example, in 2016, we began implementing new enterprise resource planning (“ERP”), business process management software in order to better manage our business and automate many back office functions with the goal of improving our internal controls over financial reporting on a consolidated basis. The full system migration was expected to be completed by the end of 2018, however, until the system reaches full implementation, distortions may occur. Prior to the adoption of these new systems, certain control functions were managed manually, without the use of technology, including the provisioning for landfill closures and judicial deposits, thus subjecting these processes to a high degree of human error. Accordingly, the process of automating these processes will require constant monitoring and potentially adjustments during thephase-in period. We cannot assure you that technological failures will not occur as a result of the ongoing implementation of this new system that could result in distortions and other problems. Inabilities and delays in implementing new systems, as well as the possibility of human failure when dealing with new systems, could affect our ability to realize projected or expected cost savings and improve our controls as anticipated. Additionally, any systems failures could impede our ability to timely collect and report financial results in accordance with applicable laws.

We rely on computer systems to run our business, and face risks from security breaches that could disrupt or damage our internal operations, information technology systems or reputation, and expose us to litigation risk.

We use computers in substantially all aspects of our business operations. We also uses mobile devices, social networking and other online activities to connect with employees and customers. Such uses give rise to cybersecurity risks, including security breach, espionage, system disruption, hacking,cyber-attack, theft and inadvertent release of information. Our business involves the storage and transmission of numerous classes of sensitive and/or confidential information and intellectual property, including customers’ personal information, private information about employees, and our financial and strategic information. Further, as we pursue our strategy to grow through strategic acquisitions in addition to internal growth, our technological presence and corresponding exposure to cybersecurity risk will increase. If we fail to assess and identify cybersecurity risks associated with acquisitions and new initiatives, we may become increasingly vulnerable to such risks.

Despite the constant monitoring of our technology systems and hiring of specialized third parties to identify and address any vulnerabilities through implementation of multi-tiered network security measures, computer programmers and hackers, or even internal users, may be able to penetrate, create systems disruptions or cause shutdowns of our network security or that of third party companies with which we have contracted. As a result, we could experience significant disruptions of our operations and incur significant expenses addressing problems created by these breaches. Such unauthorized access could disrupt our business and could result in a loss of revenue or assets and any compromise of customer information could subject us to customer or government litigation and harm our reputation, which could adversely affect our business and growth.

We may face difficulty consummating future acquisitions and we may become liable for unknown obligations of acquired companies, which may pose significant risks and could have an adverse effect on our operations.

In the past, we have grown through strategic acquisitions in addition to internal growth and may, in the future, engage in acquisitions in order to acquire or develop additional disposal capacity or businesses that are complementary to our core business strategy. We expect that increased consolidation in the solid waste services industry will continue and may reduce the number of attractive acquisition candidates. Even if we identify suitable acquisition candidates, we may nevertheless be unable to negotiate successfully the acquisition at a price or on acceptable terms and conditions, due to limitations imposed by our debt obligations, amongst others. We may have to borrow money or incur liabilities in order to finance any future obligations and may not be able to do so on favorable terms or at all. In addition, we may be unable to obtain the necessary regulatory approvals to complete potential acquisitions. The integration of acquired businesses and other assets may require significant management time and resources that would otherwise be available for the ongoing management of our existing operations.

In addition, it is possible that the operations or sites we have acquired in the past or that we may acquire in the future, have liabilities or risks with respect to former or existing operations or properties, or otherwise, which we have not been able to identify and assess through our due diligence investigations. For example, employee misconduct or a history of improper payments are not always easy to detect as part of the diligence processpre-acquisition and are frequently concealed by counterparties. Accordingly, it is possible that we could later discover that assets acquired by us have conducted business or engaged in activities that are not aligned with our ethical standards and for which we could be responsible. As a successor owner, we may be generally legally responsible for liabilities that arise from the businesses that we acquire. Even if we obtain legally enforceable representations, warranties and indemnities from the sellers of such businesses, we may not cover the liabilities fully or the sellers may not have sufficient funds to perform their obligations, as was the case in some of our past acquisitions. Some environmental liabilities, even if we do not expressly assume them, may be imposed on us under various regulatory schemes and other applicable laws regardless of whether we caused or contributed to any conditions that resulted in such liabilities. In addition, our insurance program may not cover such sites and will not cover liabilities associated with some environmental issues that may have existed prior to attachment of coverage. A successful uninsured claim against us could harm our financial condition or operating results. Furthermore, risks or liabilities of which we are unaware or judges to be not material or remote at the time of acquisition may develop into more serious risks to our business. Any adverse outcome resulting from such risks or liabilities could harm our business, results of operations and financial condition and create negative publicity, which could damage our reputation and competitive position.

We incur significant expenses and administrative burdens as a public company, which could have an adverse effect on our business, financial condition and results of operations.

We are listed as a public company, which results in increased legal, accounting, administrative and other costs and expenses as a public company that we did not incur until recently as a private company. The Sarbanes-Oxley Act as well as rules and regulations subsequently implemented by the SEC, the Dodd-Frank Wall Street Reform and Consumer Protection Act of 2010 and the rules and regulations promulgated and to be promulgated thereunder, the PCAOB and the securities exchanges, impose additional reporting and other obligations on public companies. Compliance with public company requirements increases costs and makes certain activities more time-consuming. A number of those requirements require us to carry out activities we have not done as a private company. For example, we have created board committees and are continuing to adopt internal controls and disclosure controls and procedures. In addition, we incur expenses associated with SEC reporting requirements. Furthermore, if any issues in complying with those requirements are identified (for example, the existence of material weaknesses or significant deficiencies in our internal control over financial reporting or our disclosure controls and procedures), we could incur additional costs rectifying those issues, and the existence of those issues could adversely affect our reputation or investor perceptions of us. See also “—We have identified weaknesses in our internal control over financial reporting and our disclosure controls and procedures.” If we are unable to remediate these weaknesses, or if we experience additional weaknesses in the future or otherwise fail to maintain an effective system of internal control over financial reporting and disclosure controls and procedures in the future, we may not be able to accurately or timely report our financial condition or results of operations, which may adversely affect investor confidence in us and, as a result, the value of our securities. It may also be more expensive to obtain director and officer liability insurance. Risks associated with our status as a public company may make it more difficult to attract and retain qualified persons to serve on the board of directors or as executive officers. The additional reporting and other obligations imposed by these rules and regulations increases legal and financial compliance costs and the costs of related legal, accounting and administrative activities. These increased costs require us to divert a significant amount of money that could otherwise be used to fund our business and achieve strategic objectives. Advocacy efforts by shareholders and third parties may also prompt additional changes in governance and reporting requirements, which could further increase costs.

Our management has limited experience in operating a public company.

We became a publicly traded company on December 21, 2017. Our executive officers and directors have limited experience in the management of a publicly traded company. Our management team may not successfully or effectively manage our continued operation as a public company, which subjects us to significant regulatory oversight and reporting obligations under federal securities laws. Their limited experience in dealing with the increasingly complex laws pertaining to public companies could be a significant disadvantage in that it is likely that an increasing amount of their time may be devoted to these activities which will result in less time being devoted to the management of our business and execution of our business strategies. It is possible that we will be required to hire additional employees in order to support our operations as a public company which will increase our operating costs in future periods, including increasing the number of employees in our internal audit team in order to strengthen our ability to continuously evaluate its internal control environment and procedures and seek to remediate the material weaknesses in internal control over financial reporting as described under “Item 15. Controls and Procedures.”

We may lose certain benefits afforded under Brazilian tax repayment programs if we are unable to comply with the program’s terms, and the program may not fully cover our tax liability in connection with past activities.

In 2017 and 2018, we elected to participate in certain tax amnesty programs which allowed us to settle certain of our tax debts under administrative or judicial discussion. While these programs did not provide amnesty for penalties or interest, it did allow us to resolve certain of our federal tax debts in installment payments. The program also allowed the partial settlement of tax debts with the use of tax credits and/or the use of tax loss carryforwards. In order to benefit from this program, we were required to waive in advance any defense or rights in relation to administrative disputes involving the tax indebtedness. For additional information regarding our participation in tax amnesty programs, see “Item 8.A. Financial Information—Consolidated Statements and Other Financial Information—Legal and Administrative Proceedings and Investigations” and note 17 to our audited financial statements included elsewhere in this annual report.

Despite our participation in these programs, we could be subject to tax audits for subsequent periods, which may lead to additional tax challenges by the relevant authorities on similar claims. In addition, if we are delinquent in our payments under these programs or are otherwise unable to pay as scheduled, we may be barred from participation in these programs.

Risks Related to the Waste Management Regulatory Environment

We are subject to substantial governmental regulation, and failure to comply with these requirements, as well as enforcement actions, could subject us to a shut-down of facilities, fines, penalties and judgments.

We are subject to comprehensive federal, state and, in some cases, municipal laws and regulations in connection with our operations, including environmental and other laws and regulations pertaining to (i) the management (collection, transportation, recycling, storage and disposal) of waste, (ii) atmospheric emissions of pollutants, (iii) water usage and the discharge of effluents into waterways, (iv) licensing requirements, especially relating to our landfill activities, (v) land use requirements, including the protection and preservation of forests, coastlines, caves, watersheds and other features of the ecosystem, (vi) interference into specially protected areas, such as areas of cultural and historical relevance, conservation, preservation and legal reserve areas and their surrounding regions, and (vii) a broad range of occupational health and safety regulations. In addition, under certain circumstances, Brazil’s environmental laws may impose additional costs on licenses for significant impact activities, such as landfills, with proceeds to be destined toward conservation areas.

The Brazilian Constitution grants federal, state and municipal governments the authority to issue environmental protection laws and to publish regulations based on those laws. While the Brazilian federal government has authority to issue environmental regulations setting general standards for environmental protection, state governments have the authority to issue stricter environmental regulations. Municipal governments may only issue regulations regarding matters of local interest or as a supplement to federal or state laws.

With respect to environmental licensing, pursuant to Brazilian law, the projects must be licensed by a single entity, at the federal, state or municipal level. There are certain factors that must be taken into consideration to establish the licensing jurisdiction. Nevertheless, as a general rule, IBAMA (Instituto Brasileiro do Meio Ambiente e dos Recursos Naturais Renováveis) is the competent authority for the environmental licensing of undertakings and activities of national interest or capable of causing significant environmental impact in a regionally or internationally, or for activities located in certain protected areas such as indigenous lands or territorial waters, among others. The local environmental entities, are responsible for the licensing of enterprises with a local impact. The state environmental authorities have jurisdiction to conduct the licensing process of for activities whose impacts are restricted to their territory and whose licensing jurisdiction is not assigned to federal or local agencies.

On the federal level, we are subject to IBAMA, which is part of the Brazilian Ministry for the Environment. In the state of São Paulo, the environmental agency is CETESB (Companhia Ambiental do Estado de São Paulo) and in the state of Paraná, the environmental agency is IAP (Instituto Ambiental do Paraná). In addition, in some of the larger municipalities in which we operate there are local regulators that enforce their own rules and licensing procedures. For example, in the city of São Paulo, we are subject to regulation by the Secretary for the Environment (Secretaria do Verde e Meio Ambiente).

Environmental liability may be attributed under civil, administrative and criminal spheres, with the imposition of administrative civil and criminal sanctions, despite the obligation to readdress all the damages caused. As a result, it is important to bear in mind that lack of conviction in one of these spheres does not necessarily exempt the infractor from liability arising from the remaining other matters.

The civil liability for environmental damage can subject us to environmental remediation or payment of indemnification when the environment cannot be restored. Under Federal Law No. 6,938/1981, companies are subject to strict liability for damages caused to the environment, and no statute of limitations applies. Brazilian law also imposes joint and several liability for anyone who, by virtue of a given activity, regardless of fault (intentional or negligent failure to maintain some standard of conduct, when such failure results in harm to something or someone), facilitates or contributes to environmental damage.

Therefore, we could be civilly liable if our operations cause negative impacts on human health or environmental damage to our properties or to the property of third parties, for example, as a result of the contamination of soil, groundwater or surface water, or drinking water. We may be held liable for any environmental damage that our current or former facilities cause. As part of our restructuring activities, we have recentlyspun-off or sold various assets (for additional information, see “Item 4.A. Information on the Company—History and Development of the Company—Recent Divestments and Acquisitions”), and our liability exposure would extend to these assets as well despite the fact that they are no longer under our control.

Under current Brazilian law, the owners of real property are jointly and severally liable with the party that has caused damage to the environment for the restoration of the environment and/or the payment of indemnification, i.e. we may be responsible for repairing an asset that was environmentally degraded before our acquisition. We may also be liable for anyon-site environmental contamination caused by pollutants or hazardous substances related to our or our predecessors’ activities.

In the event any of the risks described above, or any unforeseen risks in relation to our compliance with applicable regulation, materialize, we may need to shut down or reduce operation of our facilities while expensive and time-consuming remedial actions are undertaken. We may be required to spend substantial capital to bring an operation or an asset into compliance, to temporarily or permanently discontinue activities and/or take corrective actions, possibly including the removal of landfilled materials.

In addition, we may also be subject to administrative and criminal sanctions or penalties, pursuant to Federal Law No. 9,605/98 (Environmental Crimes Law), which regulates certain conduct that is considered criminal conduct. According to such law, both corporations and individuals may be subject to criminal liability. Thus, corporations found to be wrongdoers may be subject to (i) partial or total interruption of operations, (ii) temporary suspension of construction work or activity, and (iii) prohibition of contracting with governmental authorities, and obtaining governmental subsidies, incentives or donations. Executive officers, directors, managers and other individuals from companies found to be polluting may be subject to fines, required to render community service or may be imprisoned for up to five years.

Moreover, administrative penalties may also be imposed whenever there is a breach of environmental laws, according to Federal Decree No. 6,514/2008, and such penalties include: (i) warnings; (ii) restriction of rights; (iii) suspension or prohibition of installation or development of activities; (iv) prohibition to contract with the government; (v) license suspension; (vi) suspension of financing or tax benefits; and (vii) fines. The fines applicable to polluters or those that do not comply with the legal provisions on waste management range from R$50 to R$50 million.

In any of these cases, we may experience negative publicity in addition to liability for environmental remediation. Associated costs with any of these outcomes could be significant to us and impact our results of operations, cash flows and available capital. We may not have sufficient insurance coverage for our environmental liabilities, such coverage may not cover all of the potential liabilities to which we may be subject and we may not be able to obtain insurance coverage in the future at reasonable expense or at all. While we seek to minimize our exposure to such risks through comprehensive training and compliance programs, as well as vehicle and equipment maintenance programs, if we were to incur substantial liabilities in excess of any applicable insurance, our business, results of operations and financial condition could be adversely affected.

In the ordinary course of business, we have in the past, are currently, and may in the future, become involved in legal and administrative proceedings relating to land use and environmental laws and regulations. These include proceedings relating to environmental claims, with noteworthy reference to certain rules established by Brazil’s labor public ministry. The provisions established for the proceedings to which we are party to may be insufficient to cover the total cost resulting from such proceedings, and an adverse outcome of one or more of these proceedings could result in, among other things, material increases in our costs or liabilities as well as material charges for asset impairments.

Future changes in regulations, particularly in relation to our landfill operations, may result in increased liabilities and impose additional compliance costs, which could adversely affect us.

Our operations, particularly our disposal activities, may be adversely affected by changes in governmental laws or regulations, including measures seeking to address global warming or reducing the environmental impact of our operations generally. In particular, legislative changes may result in new or more stringent environmental standards imposed on us which could require additional capital commitments from us, including as a result of the need to modify or replace equipment or facilities. In addition, legislative changes may affect our ability to operate our landfills at full capacity by reclassifying items in the waste stream as hazardous, prohibiting the disposal of certain wastes, impacting the demand for landfill space, or decreasing the tipping fees and prices that we can charge for utilization of landfill space, each of which could increase the costs and decrease the profitability levels associated with the services we provide. Regulatory changes affecting the siting, design and closure of landfills could require us to undertake investigatory or remedial activities, curtail operations or close landfills temporarily or permanently.

With respect to landfill operations, we have significant financial obligations relating to final capping, closure,post-closure and environmental remediation at our existing landfills. We established accruals for these estimated costs, but could underestimate such accruals. Environmental regulatory changes could accelerate or increase capping, closure, post-closure and remediation costs, requiring expenditures to materially exceed our current accruals.

Moreover, our landfill operations produce methane as well as other biogases, which we process at our facilities to emit the greenhouse gases carbon dioxide and carbon monoxide. There are a number of legislative and regulatory efforts at the state, regional and federal levels to curtail the emission of greenhouse gases, among other emissions, to ameliorate the effect of climate change. Legislation and increased regulation regarding climate change could impose significant costs on us and our suppliers, including costs related to increased energy requirements, capital equipment, environmental monitoring and reporting and other costs to comply with such regulations. Given the emotion, moral and political significance and the uncertainty around the impact of climate change and how it should be dealt with, we cannot predict how legislation and regulation will affect our financial condition, operating performance and ability to compete. Even without such regulation, increased awareness and any adverse publicity in the global marketplace about potential impacts on climate change by us or other companies in our industry could harm our reputation. The potential physical impacts of climate change on our operations are highly uncertain, and would be particular to the geographic circumstances in areas in which we operate. These impacts may adversely impact the cost, potential production and financial performance of our operations.

It is also possible that government officials responsible for enforcing environmental laws and regulations may believe an issue is more serious than expected, or that we will fail to identify or fully appreciate an existing liability before we become legally responsible for addressing it. Some of the legal sanctions to which we could become subject could cause the suspension or revocation of a needed permit or license required for our operations, prevent us from, or delay us in, obtaining or renewing permits or licenses to operate or expand our facilities, or harm our reputation.

The implementation and progression of product stewardship policies and take-back requirements, may reduce demand for the services we provide, which could adversely affect us.

Environmental initiatives, such as product stewardship and take-back requirements, which hold manufacturers and other actors responsible for the disposal of manufactured goods and other products throughout such products’ life cycle, may reduce the volume of products that enter the waste stream. In Brazil, Federal Law No. 12,305/2010 established the National Solid Waste Policy, which sets out a framework of shared responsibility among manufacturers, importers, distributors, retailers, consumers and governmental agents for the life cycle of certain products, and places specific obligations on each of these entities across the waste management chain with a view toward reducing the volume of solid residues and mitigating the adverse impact on human health and the environment.

Under the existing regulatory framework, such actors are charged with taking back and managing certain products and packaging at their end of life, and participating in the actions provided for by MSW management plans in relation to those products and packaging not yet subject to the take-back obligation, provided that this participation has been agreed with municipalities. Take-back is currently mandatory for the following products: (i) pesticides and their packaging, as well as other hazardous packaging, (ii) batteries, (iii) tires, (iv) lubricants and lubricant packaging, (v) lamps as well as (vi) electric and electronic equipment. For other products and packaging, take-back may be made mandatory by means of specific agreements entered into by manufacturers, importers, distributors and sellers, on the one hand, and governmental authorities, on the other hand. If further take-back regulations were adopted, they could have a fundamental impact on the waste streams that we manage and how we operate our business, including contract terms and pricing. A significant reduction in the waste, recycling and other streams we manage could have a material adverse effect on our financial condition, results of operations and cash flows.

The waste management industry in Brazil is undergoing fundamental change as traditional waste streams are increasingly viewed as renewable resources, which could cause customers to seek alternatives to landfill disposal which could result in a decline in our revenues and operating results.

As we have continued to develop our landfill capacity, the waste management industry has increasingly recognized the value of the waste stream as a renewable resource and new alternatives to landfills are being developed that seek to maximize the renewable energy and other resource benefits of waste. Although most of these efforts are still in the research orpre-operational phase, and a significant portion of Brazil’s MSW is still being disposed of in more rudimentary open dumps, future technological advances in the waste management industry may result in increasing competition from companies that seek to use parts of the waste stream as feedstock for renewable energy supplies. As a result of such increased competition, our revenues and operating margins could be adversely affected.

In addition, we are increasingly vigilant in monitoring growing worldwide support for “zero landfill” programs, which encourage the redesign of resource life cycles with the ultimate goal of eliminating waste being sent to landfills. Implementation of such programs typically take up to ten years, and the movement in Brazil is still incipient and is just starting to gain momentum. Nevertheless, many important multinational industrial companies operating in Brazil have already indicated a commitment to a “zero landfill” philosophy and are demanding solutions to meet these ambitions. Progression of this industry trend toward a “zero landfill” philosophy could have a fundamental impact on the waste streams we manage and how we operate our business, potentially requiring, among other things, significantly increased investments in value recovery technologies to meet this changing market demand. Increased movement toward a “zero landfill” philosophy could result in higher capital commitments by us into new technologies than currently anticipated, as well as a significant reduction in the role played by our landfills in the Brazilian waste cycle, each of which could have a material adverse effect on our financial condition, results of operations and cash flows.

The provision of environmental and waste management services involves risks, such as truck accidents, equipment defects, malfunctions and failures, abnormal weather conditions and natural disasters, which may not be covered by insurance and could adversely affect our operations and financial condition.

The provision of environmental and waste management services involves inherent risks, such as truck accidents, equipment defects, malfunctions and failures and natural disasters, which could partially interrupt our activities and potentially result in releases of hazardous materials, injury or death of employees, among other negative consequences. These risks include increased rainfall and flooding, fires or explosions, natural disasters, criminal acts, malfunction of equipment and emission of toxic substances, and could expose us to potential liability for pollution and other environmental damages, personal injury, loss of life, business interruption and property damage or destruction. For example, increased rainfall can result in landslides that could threaten our landfills and other infrastructure and limit road transportation, and could also lead to flooding which could restrict our operations and damage our landfills and other facilities, and consequently, result in an increase in operational costs for environmental remediation and treatment of leachate, as well as other cost additions related to landfill operation. In addition, abnormal weather conditions and natural disasters could disrupt our electric power supply, which could affect certain of our activities, such as pumping and shredding, which could adversely affect our waste treatment activities. Finally, the effects of climate change could create impacts and losses in any part of our business operations, for instance, by causing extreme floods.

As a result, our activities could be significantly affected or even paralyzed. These risks could result in property damage, loss of revenue, loss of life, pollution and harm to the environment, among others. If any of these occur, we may be exposed to economic sanctions, damages, fines or penalties in addition to the costs required to repair or remediate the related damage. Moreover, any interruption in production capability may require us to make additional capital expenditures to remedy the problem, which would reduce the amount of cash available for our operations. These costs, fines and penalties may adversely affect our financial condition and results of operations.

Our insurance may not cover losses and liabilities resulting from such incidents. Such incidents could also harm our reputation and result in a loss of customers, which could adversely affect us.

Disagreements with the local communities where we operate can have a negative impact on our business and reputation.

We currently operate, and plan to further expand our operations, in areas considered close to communities and other population centers, including in connection with our landfill operations. Such presence could disproportionately impact certain segments of the population in these areas, or affect vulnerable demographic group (actually or perceived), which could lead to disagreements with surrounding communities, local leaderships, community associations, organized social movements and local government. In order to undertake our activities, we may be required to first consult with such groups and negotiate with them as a condition to obtaining local government approvals and the necessary operating licenses.

Our activities may be subject to opposition, including protests by various communities, even in areas in which we are not required to engage in a consultation process. Disagreements or legal disputes with these local forces could cause delays or disruptions in our operations, result in operational restrictions, adversely affect our reputation or otherwise impair its ability to conduct our operations, thus adversely affecting our business and the viability of planned projects. No assurances can be given that we will successfully reach an agreement with the different community forces opposed to our operations or that such communities will participate in consultation processes.

Our insurance may not cover losses and liabilities resulting from such incidents. Such incidents could also harm our reputation and result in a loss of customers, which could adversely affect us.

Risks Related to Brazil

The Brazilian government has exercised, and continues to exercise, significant influence over the Brazilian economy. This influence, as well as Brazilian political and economic conditions, could adversely affect us.

The Brazilian government frequently intervenes in the Brazilian economy and occasionally makes significant changes in policy and regulations. The Brazilian government’s actions designed to control inflation, stimulate growth and other policies and regulations have often involved, among other measures, increases in interest rates, changes in tax policies, price controls, currency devaluations, capital controls and limits on imported goods and services. We cannot control or predict changes in policy or regulations that the Brazilian government might adopt in the future.

We may be adversely affected by the economic and political conditions in Brazil as well as changes in policy or regulations at the federal, state or municipal levels involving or affecting factors such as:

•

economic, social and political instability, including allegations of corruption against political parties, elected officials or other public officials, such as those allegations made in relation to theLava Jatoinvestigation;

•

expansion or contraction of the Brazilian economy, as measured by GDP growth rates;

•

interest rate fluctuations;

•

currency and exchange rate fluctuations;

•

inflation;

•

volatility and liquidity of domestic capital and lending markets;

•

tax policies;

•

environmental policy;

•

labor regulations;

•

energy and water shortages and rationing;

•

foreign exchange controls and restrictions on remittances abroad, such as those restrictions that were briefly imposed in 1989 and early 1990; and

•

other economic, political and social developments in or affecting Brazil.

Brazil is currently recovering from a recession, and continued weaknesses in the Brazilian macroeconomic environment, including a low savings rate, a high interest rate spread and high public indebtedness, could adversely affect us.

Brazil is currently recovering from a recession, and material weaknesses and imbalances continue to threaten macroeconomic stability and the future prospects of the Brazilian economy, including:

•

a notably low savings rate at 6.2% as of December 31, 2018, according to the Brazilian Central Bank;

•

one of the highest headline interest rates in the world at 6.4% as of December 31, 2018, according to CETIP;

•

a relatively high level public indebtedness, representing 53.8% of Brazil’s gross domestic product (“GDP”) as of December 31, 2018, according to the Brazilian Central Bank; and

•

a R$120.3 billion federal budget primary deficit in 2018, according to the Brazilian Central Bank.

For more information, see “Item 5.A. Operating and Financial Review and Prospects—Operating Results—Brazilian Macroeconomic Environment.” We cannot predict what measures the Brazilian government will take in the face of mounting macroeconomic pressures or otherwise or how continued weak macroeconomic conditions may affect us.

Uncertainty over whether the Brazilian government will implement changes in policy or regulation in order to address the current economic challenges affect economic performance and contribute further to economic uncertainty in Brazil and to heightened volatility in the Brazilian financial markets. For more information, see “Item 5.A. Operating and Financial Review and Prospects—Operating Results—Brazilian Macroeconomic Environment.”

The persistence or intensification of the economic crisis in Brazil and the uncertainty over whether the Brazilian government will implement changes in policy or regulation in order to address the current economic challenges could adversely affect us.

Brazil continues to experience political instability, which may adversely affect us.

Brazil’s political environment has historically influenced, and continues to influence, the performance of the country’s economy. Political crises have affected and continue to affect the confidence of investors and the general public, which have historically resulted in economic deceleration and heightened volatility in the securities issued by Brazilian companies.

Brazil has experienced heightened economic and political instability derived from various currently ongoing investigations into allegations of money laundering and corruption being conducted by the Office of the Brazilian Federal Prosecutor, including the largest such investigation, known asLava Jato, which have negatively impacted the Brazilian economy and political environment and contributed to a decline in market confidence in Brazil.

As a result of these investigations, a number of senior politicians, including members of Congress, and high-ranking executive officers of major corporations and state-owned companies in Brazil, have been arrested, convicted of various charges relating to corruption, entered into plea agreements with federal prosecutors and/or have resigned or been removed from their positions as a result of theseLava Jato investigations. These individuals are alleged to have accepted bribes by means of kickbacks on contracts granted by the government to several infrastructure, oil and gas and construction companies. The profits of these kickbacks allegedly financed the political campaigns of political parties forming the former government’s coalition that was led by former President Dilma Rousseff, which funds were unaccounted for or not publicly disclosed. These funds were also allegedly destined toward the personal enrichment of certain individuals.

Amidst this background of political and economic uncertainty, President Dilma Rousseff was suspended from office on May 12, 2016, when the Brazilian Senate voted to hold a trial on impeachment charges against her. President Rousseff was replaced by then Vice-President Michel Temer, who served as acting President until Ms. Rousseff was permanently removed from office by the Senate on August 31, 2016. Former President Temer’s term of office ended in December 2018.

In May 2017, several motions for impeachment proceedings against former President Temer were filed in Congress by opposition parties following the surfacing of allegations that Mr. Temer had appeared to endorse the bribing of a jailed politician. On June 26, 2017, Brazil’s chief prosecutor initiated criminal indictment proceedings against former President Temer, which were then referred to Congress for an indictment decision. On August 2, 2017, Congress decided by a majority vote against criminally indicting former President Temer on these charges, and the charges were dismissed for the remainder of his term in office. On an unrelated proceeding, on June 9, 2017, the Brazilian Supreme Court decided that there was insufficient evidence to rule against former President Temer and former President Rousseff on charges relating to illegal campaign financing during former President Temer and former President Rousseff’s 2014 election campaign. On September 14, 2017, Brazil’s chief prosecutor brought additional criminal charges against former President Temer, which were then referred to Congress for an indictment decision. On October 25, 2017, Congress decided by a majority vote against criminally indicting former President Temer on these new charges. On March 21, 2019, former President Temer was arrested for a period of four nights pursuant to an order by a Brazilian federal judge as a precautionary measure in a case involving alleged kickbacks to secure a contract to build a nuclear power plant in Rio de Janeiro state.

Uncertainty regarding the 2018 elections in Brazil also had an adverse effect on the economy and the general public, particularly the incarceration of the former president of Brazil Luiz Inacio Lula da Silva, who was leading polls as a top contender to win the presidential election when he began serving a12-year prison sentence on corruption and money laundering charges in April 2018. In July 2017, Mr. da Silva was convicted on corruption and money laundering charges and sentenced to almost 10 years in prison, and in January 2018, an appeals court unanimously upheld the conviction and decrease the sentence to 8 years. The warrant for Mr. da Silva’s incarceration was issued after Brazil’s highest court rejected his bid to remain out of prison while appeals of the conviction were considered.

Although Mr. Jair Bolsonaro was elected in November 2018 and took office on January 1, 2019, it remains to be seen whether the proposed economic changes and policies to be adopted will be effective in producing political stability and economic growth. See “—Policies under the new administration of Jair Bolsonaro, Brazil’s recently inaugurated president, may adversely affect the Brazilian economy, our business and the market price of our securities.”

We believe that some continued political instability in Brazil and new allegations of wrongdoing involving Brazilian public officials are likely. We have no control over, and cannot predict, whether such investigations or allegations will lead to further political and economic instability or whether new allegations against government officials will arise in the future or will adversely affect us.

Any of the above factors may create additional political uncertainty, which could have a material adverse effect on the Brazilian economy our business, financial condition and results of operations.

Policies under the new administration of Jair Bolsonaro, Brazil’s recently inaugurated president, may adversely affect the Brazilian economy, our business and the market price of our securities.

During his presidential campaign, Jair Bolsonaro was reported to favor the privatization of state-owned companies, economic liberalization, and social security and tax reforms. However, there is no guarantee that Bolsonaro will be successful in executing his campaign promises or passing certain favored reforms fully or at all, particularly when confronting a fractured congress.

Moreover, Jair Bolsonaro was generally a polarizing figure during his campaign for presidency, particularly in relation to certain of his social views, and we cannot predict the ways in which a divided electorate may continue to impact his presidency and ability to implement policies and reforms, all of which could have a negative impact on our business.

The Brazilian economy and we may be negatively impacted by exchange rate instability.

The Brazilian currency has been historically volatile and has been devalued frequently over the past three decades. Since 1999, the Central Bank has allowed thereal/U.S. dollar exchange rate to float freely and during this period, thereal/U.S. dollar exchange rate has experienced frequent and substantial variations in relation to the U.S. dollar and other foreign currencies. Throughout this period, the Brazilian government has implemented various economic plans and used various exchange rate policies, including sudden devaluations, periodic mini-devaluations (during which the frequency of adjustments has ranged from daily to monthly), exchange controls, dual exchange rate markets and a floating exchange rate system. Although long-term depreciation of the realis 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 thereal, the U.S. dollar and other currencies. We cannot predict whether the Central Bank or the Brazilian government will continue to let the real float freely or intervene in the exchange rate market by returning to a currency band system or otherwise. The real may depreciate or appreciate substantially against the U.S. dollar. Furthermore, Brazilian law provides that, whenever there is a serious imbalance, the Brazilian government may impose temporary restrictions on the remittances of foreign capital abroad and on the conversion of Brazilian currency into foreign currencies. We cannot assure you that such measures will not be taken by the Brazilian government in the future.

Thereal/U.S. dollar exchange rate reported by the Central Bank was R$3.8742 per U.S. dollar on December 31, 2018, reflecting a 17.1% appreciation against the U.S. dollar as compared to R$3.3080 per U.S. dollar on December 31, 2017, which, in turn, reflected a 16.5% appreciation against the U.S. dollar as compared to R$3.9048 per U.S. dollar on December 31, 2015. On September 24, 2015, thereal fell to the lowest level since the introduction of the currency, at R$4.195 per US$1.00. As of December 31, 2018, thereal/ U.S. dollar exchange rate was R$3.8742 per U.S. dollar, reflecting a 17.1% depreciation against the U.S. dollar as compared to December 31, 2017. Thereal has fluctuated significantly over the course of 2018 due in part to the general strengthening of the U.S. dollar worldwide and reflecting lower Brazilian interest rates and a high degree of political uncertainty.

Depreciation of thereal could create inflationary pressures in Brazil and cause increases in interest rates, which could negatively affect the growth of the Brazilian economy as a whole, harm us, curtail access to financial markets and prompt government intervention, including recessionary governmental policies. Depreciation of thereal can also, as in the context of the current global economic recovery, lead to decreased consumer spending, and reduced growth of the economy as a whole.

Because of the degree of volatility and the uncertainty of the factors that impact the Brazilianreal’s exchange rate, it is difficult to predict future exchange rate movements. In addition, the Brazilian government may change its foreign currency policy, and any governmental interference in the exchange rate, or the implementation of exchange control mechanisms, could influence the real’s exchange rate.

An increase in inflation, as well as government efforts to combat inflation, may hinder the growth of the Brazilian economy and could adversely affect us.

In the past, Brazil has at times experienced extremely high rates of inflation. Inflation and some of the measures taken by the Brazilian government in an attempt to curb inflation have historically had significant negative effects on the Brazilian economy generally and on Brazil’s capital markets. According to the National Consumer Price Index (Índice Nacional de Preços ao Consumidor Amplo) (“IPCA”), Brazilian inflation rates were 3.75%, 2.95%, and 6.29% in 2018, 2017 and 2016, respectively.

If Brazil experiences high inflation again in the future, our operating expenses and borrowing costs may increase while our operating and net margins may decrease. Inflationary pressures may also adversely affect our ability to access foreign capital markets, adversely affecting us. Conversely, more lenient government and Central Bank policies and interest rate decreases have triggered and may continue to trigger increases in inflation, and, consequently, growth volatility and the need for sudden and significant interest rate increases, which could negatively affect us and increase our indebtedness.

Inflationary pressures may also lead the Brazilian government to intervene in the economy and introduce policies that could adversely affect us. In the past, the Brazilian government’s interventions included the maintenance of a restrictive monetary policy with high interest rates. For example, the official interest rate in Brazil increased from 7.25% in 2013 to 14.25% in 2015, as established by the Brazilian Monetary Policy Committee (Comitê de Política Monetária do Banco Central do Brasil). The official interest rate in Brazil was lowered from 14.25% to 14.00% to 13.75% in 2016, and was lowered to 6.75% on February 7, 2018, with further lowering to 6.50% in March 2018. There have been no changes to the official interest rate between then and December 31, 2018.

The government’s high interest rate policies have historically restricted credit availability and reduced economic growth, and may reduce our ability to execute our business and management plans and adversely affect us in the future. In addition, as of December 31, 2017, the interest rates of substantially all of our loans, financing and debentures and related debt acknowledgment instrument were directly tied to the interest rates in Brazil, such as the Brazilian long-term interest rate (Taxa de Juros de Longo Prazo) (“TJLP”) and the interbank deposit rate (Certificados de Depósitos Interbancários) (“CDI”). An increase in such interest rates would increase our borrowing costs and may affect our ability to comply with our financial obligations, which could adversely affect us.

We are exposed to variations in interest rates, which may have adverse effects on us.

We are exposed to the risk of interest rate variations, principally in relation to Brazil’s TJLP, Brazil’s CDI, and Brazil’s consumer price index (Índice de Preço ao Consumidor) (“IPC”). As of December 31, 2018, all of our debt was indexed to Brazilian interest rates, principally the CDI. If these interest rates were to increase, this could adversely affect us by increasing expenses in making the repayments and could restrict our ability to access financing in the future. We may not be able to adjust the prices we charges to our customers to offset increased debt payments, particularly as our contracts with our customers are typically for a term of four years.

As of December 31, 2018, the outstanding balance due on our loans subject to the CDI rate was R$1,552.4 million (R$1,448.2 million as of December 31, 2017).

Significant increases in consumption, inflation or other macroeconomic pressures may lead to an increase in these rates. For further information regarding our exposure to the risk of interest rate variations, see “Item 5.A. Operating and Financial Review and Prospects—Operating Results—Brazilian Macroeconomic Environment.”

The Brazilian government’s inefficiencies or inability to implement critical reforms to improve the Brazilian tax system, labor laws and other areas key to macroeconomic vitality may negatively impact us.

Legislative rigidities, particularly in the goods and labor markets, continue to negatively impact the competitiveness and productivity of the Brazilian economy and hinder the allocation of resources to their most efficient use. Distortionary excise taxes, taxation on investments and a lack of flexibility in the Brazilian labor market are hindrances to continued and robust economic growth in Brazil. In addition, the Brazilian legal and administrative framework within which individuals, firms, and governments interact remains encumbered by bureaucratic constraints. Furthermore, a low confidence level in Brazilian government officials and in the rule of law continues to pose additional challenges. There can be no assurances that the Brazilian government will implement reforms adequately addressing these impediments to greater economic growth and, as a result, we may be adversely affected.

Risks Related to Our Ordinary Shares

We could be adversely affected by any further downgrading of Brazil’s credit rating.

Credit ratings affect investors’ perceptions of risk and, as a result, the yields required on future debt issuances in the capital markets. Rating agencies regularly evaluate Brazil and its sovereign ratings, which are based on a number of factors including macroeconomic trends, fiscal and budgetary conditions, indebtedness metrics and the perspective of changes in any of these factors.

Rating agencies began the classification review of Brazil’s sovereign credit rating in September 2015, and Brazil subsequently lost its investment grade condition by the three main rating agencies. Standard & Poor’s Financial Services LLC initially reduced Brazil’s credit rating fromBBB-minus toBB-plus and subsequently reduced it again fromBB-plus to BB, and maintained its negative outlook on the rating, citing a worsening credit situation since the first downgrade. In December 2015, Moody’s Investors Service, Inc. placed Brazil’s Baa3 issuer and bond ratings on review for a downgrade, and subsequently downgraded Brazil’s issuer and bond ratings to below investment grade, to Ba2 with a negative outlook, citing the prospect for further deterioration in Brazil’s debt metrics in a low growth environment, in addition to challenging political dynamics. In April 2018 Moody’s placed Brazilian sovereign outlook as stable. Fitch Ratings Inc. downgraded Brazil’s sovereign credit rating toBB-plus with a negative outlook, citing the country’s rapidly expanding budget deficit and worse-than-expected recession. As a result, Brazil lost its investment grade status from all three major rating agencies and consequently the trading prices of securities of the Brazilian debt and equity markets were negatively affected. In January 2018, Standard & Poor’s lowered its long-term rating for Brazil sovereign debt toBB-, citing less timely and effective policymaking, and a risk of greater policy uncertainty after Brazil’s 2018 elections. A continuation of the current Brazilian recession and political uncertainty could lead to further ratings downgrades.

Any further downgrade of Brazil’s sovereign credit ratings could heighten investors’ perception of risk and could, adversely affect us.

Future issuances of any equity securities may dilute your ownership interests and decrease the trading price of our ordinary shares.

Any future issuance of equity securities could dilute the interests of our shareholders and could substantially decrease the trading price of our ordinary shares. We may issue equity or equity-linked securities in the future, including pursuant to a private investment in public equity (“PIPE”) or other offering of equity securities, for a number of reasons, including to finance our operations and business strategy (including in connection with acquisitions and other transactions), to adjust our ratio of debt to equity, to satisfy our obligations upon the exercise of then-outstanding options or other equity-linked securities, if any, in connection with the terms of any possible debt restructuring efforts, in connection with any judicial reorganization or for other reasons. We are not required to obtain shareholder approval for the issuance of additional ordinary shares, and investors should note that we are not required to comply with the NASDAQ rule requiring shareholder approval for issuances of additional securities exceeding 20% of our outstanding ordinary shares. See “Item 16. Corporate Governance.”

Future sales of ordinary shares held by significant shareholders, or market expectations as to any such future sales, may increase the volatility in the price of the ordinary shares and negatively impact the trading price of the ordinary shares.

If any significant shareholder sells large amounts of ordinary shares in the open market or in privately negotiated transactions, or if the market has expectations as to any such future sales, this could have the effect of increasing the volatility in the price of the ordinary shares and negatively impact the trading price of the ordinary shares.

The Registrant is a Cayman Islands exempted company and, because judicial precedent regarding the rights of shareholders is different under Cayman Islands law than under U.S. law, you could have less protection of your shareholder rights than you would under U.S. law.

The Registrant’s corporate affairs are governed by our Memorandum and Articles, the Companies Law, as amended, and the common law of the Cayman Islands. The rights of shareholders to take action against the directors, actions by noncontrolling shareholders and the fiduciary responsibilities of our directors to us under Cayman Islands law are to a large extent governed by the common law of the Cayman Islands. 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, which has persuasive, but not binding, authority on a court in the Cayman Islands. The rights of our shareholders and the fiduciary responsibilities of our directors under Cayman Islands law are different from under statutes or judicial precedent in some jurisdictions in the United States. In particular, the Cayman Islands has a different body of securities laws from the United States and may provide significantly less protection to investors. In addition, some U.S. states, such as Delaware, have different bodies of corporate law than the Cayman Islands.

We have been advised by our Cayman Islands legal counsel, Maples and Calder, that the courts of the Cayman Islands are unlikely (i) to recognize or enforce against us judgments of courts of the United States predicated upon the civil liability provisions of the securities laws of the United States or any State and (ii) in original actions brought in the Cayman Islands, to impose liabilities against us predicated upon the civil liability provisions of the securities laws of the United States or any State, so far as the liabilities imposed by those provisions are penal in nature. In those circumstances, although there is no statutory enforcement in the Cayman Islands of judgments obtained in the United States, the courts of the Cayman Islands will recognize and enforce a foreign money judgment of a foreign court of competent jurisdiction without retrial on the merits based on the principle that a judgment of a competent foreign court imposes upon the judgment debtor an obligation to pay the sum for which judgment has been given provided certain conditions are met. For a foreign judgment to be enforced in the Cayman Islands, such judgment must be final and conclusive and for a liquidated sum, and must not be in respect of taxes or a fine or penalty, inconsistent with a Cayman Islands judgment in respect of the same matter, impeachable on the grounds of fraud or obtained in a manner, and or be of a kind the enforcement of which is, contrary to natural justice or the public policy of the Cayman Islands (awards of punitive or multiple damages may well be held to be contrary to public policy). A Cayman Islands Court may stay enforcement proceedings if concurrent proceedings are being brought elsewhere. There is recent Privy Council authority (which is binding on the Cayman Islands Court) in the context of a reorganization plan approved by the New York Bankruptcy Court which suggests that due to the universal nature of bankruptcy/insolvency proceedings, foreign money judgments obtained in foreign bankruptcy/insolvency proceedings may be enforced without applying the principles outlined above. However, a more recent English Supreme Court authority (which is highly persuasive but not binding on the Cayman Islands Court), has expressly rejected that approach in the context of a default judgment obtained in an adversary proceeding brought in the New York Bankruptcy Court by the receivers of the bankruptcy debtor against a third party, and which would not have been enforceable upon the application of the traditional common law principles summarized above and held that foreign money judgments obtained in bankruptcy/insolvency proceedings should be enforced by applying the principles set out above, and not by the simple exercise of the Courts’ discretion. Those cases have now been considered by the Cayman Islands Court. The Cayman Islands Court was not asked to consider the specific question of whether a judgment of a bankruptcy court in an adversary proceeding would be enforceable in the Cayman Islands, but it did endorse the need for active assistance of overseas bankruptcy proceedings. We understand that the Cayman Islands Court’s decision in that case has been appealed and it remains the case that the law regarding the enforcement of bankruptcy/insolvency related judgments is still in a state of uncertainty.

The Registrant may be treated as a U.S. corporation for U.S. federal income tax purposes.

As an exempted company incorporated under the laws of the Cayman Islands, the Registrant is generally classified as anon-U.S. entity (and, therefore, not a U.S. person) under general rules of U.S. federal income taxation. Section 7874 of the Code and the Treasury regulations promulgated thereunder, however, contain rules that may cause anon-U.S. corporation to be treated as a U.S. corporation for U.S. federal income tax purposes in certain cases. Whether the rules of section 7874 apply to cause the Registrant to be treated as U.S. corporation for U.S. federal income tax purposes depends on the application of complex statutory and regulatory rules to the steps of thePre-Closing Restructuring, the Merger, and certain related transactions. There is limited guidance regarding the application of the rules of section 7874 to thePre-Closing Restructuring, the Merger, and certain related transactions.

Based on the terms of thePre-Closing Restructuring, the Merger, and certain related transactions, we do not expect that the Registrant is treated as a U.S. corporation for U.S. federal income tax purposes. Nevertheless, the application of section 7874 is uncertain and depends, in part, on the application of complex rules, the application of which is uncertain. Accordingly, there can be no assurance that the IRS will not assert that the Registrant is treated as a U.S. corporation for U.S. federal income purposes pursuant to section 7874, or that a court would not uphold such an assertion. If the Registrant is treated as a U.S. corporation for U.S. federal income tax purposes, the Registrant could be liable for substantial U.S. federal income tax, dividends paid tonon-U.S. shareholders could be subject to U.S. withholding tax and certain other U.S. federal income tax consequences could apply to the Registrant that would adversely affect our tax and financial position. See “Item 10.E. Additional Information—Taxation—U.S. Federal Income Tax Considerations” for a more complete discussion of certain U.S. federal income tax considerations relating to the ownership and disposition of our ordinary shares.

As a “foreign private issuer” under the rules and regulations of the SEC, we are permitted to, and will, file less or different information with the SEC than a company incorporated in the United States or otherwise subject to these rules, and may follow certain home country corporate governance practices in lieu of certain NASDAQ requirements applicable to U.S. issuers.

We are considered a “foreign private issuer” under the Exchange Act and are therefore exempt from certain rules under the Exchange Act, which impose certain disclosure requirements for U.S. and other issuers. Moreover, we are not required to file periodic reports and financial statements with the SEC as frequently or within the same time frames as U.S. companies with securities registered under the Exchange Act. We currently prepare our financial statements in accordance with IFRS. We will not be required to file financial statements prepared in accordance with or reconciled to U.S. GAAP so long as our financial statements are prepared in accordance with IFRS as issued by the IASB. 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.

Furthermore, as a “foreign private issuer” whose ordinary shares are listed on the NASDAQ, we are permitted to follow certain home country corporate governance practices in lieu of certain NASDAQ Global Market requirements. A foreign private issuer must disclose in its Annual Reports filed with the SEC each NASDAQ requirement with which it does not comply followed by a description of its applicable home country practice. With effect from the date of this annual report, we follow home country practice that does not require us to obtain shareholder approval for issuing additional securities exceeding 20% of our outstanding ordinary shares. See “Item 16. Corporate Governance.”

We could lose our status as a “foreign private issuer” under current SEC rules and regulations if more than 50% of our outstanding voting securities become directly or indirectly held of record by U.S. holders and 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. 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 periodic reports and annual and quarterly financial statements as if we were a company incorporated in the United States. If this were to happen, we would likely incur substantial costs in fulfilling these additional regulatory requirements 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 qualify as an emerging growth company within the meaning of the Securities Act, which could make our securities less attractive to investors and may make it more difficult to compare our performance to the performance of other public companies.

We qualify as an “emerging growth company” as defined in Section 2(a)(19) of the Securities Act, as modified by the JOBS Act. As such, we are 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 continues to be an emerging growth company, including (i) the exemption from the auditor attestation requirements with respect to internal control over financial reporting under Section 404(b) of the Sarbanes-Oxley Act, (ii) the exemptions fromsay-on-pay,say-on-frequency andsay-on-golden parachute voting requirements and (iii) reduced disclosure obligations regarding executive compensation in our 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 ordinary shares that are held bynon-affiliates exceeds US$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 US$1.07 billion or more during such fiscal year (as indexed for inflation), (iii) the date on which we have issued more than US$1 billion innon-convertible debt in the prior three-year period or (iv) the last day of the fiscal year following the fifth anniversary of the date of the first sale of our ordinary shares in our initial public offering. In addition, Section 107 of the JOBS Act also 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 we are 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 may elect not to avail itself of this exemption from new or revised accounting standards 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 the ordinary shares and our stock price may be more volatile.

We have a staggered board of directors, which could impede an attempt to acquire our company or remove our management.

Our Memorandum and Articles provide for a board of directors that is divided into three classes, each of which serves for a staggered term of three years.

A staggered board makes it more difficult for shareholders to change a majority of the directors since only approximatelyone-third of the existing board of directors may be replaced at any election of directors. This arrangement may have the effect of keeping the current members of our board of directors in control for a longer period of time than shareholders may desire, and may impede any attempts to take over our company or change or remove our management.

An active or liquid trading market for our ordinary shares may not be maintained and the trading price for our ordinary shares may fluctuate significantly.

An active, liquid trading market for our ordinary shares may not be maintained in the long term and we cannot be certain that any trading market for our ordinary shares will be sustained or that the present price will correspond to the future price at which our ordinary shares will trade. Loss of liquidity could increase the price volatility of our ordinary shares.

Any additional issuance of our ordinary shares would dilute the positions of existing investors in our ordinary shares and could adversely affect the market price of our ordinary shares. We cannot assure you that our ordinary shares will not decline below their prevailing market price. You may be unable to sell your ordinary shares at a price that is attractive to you.

We rely principally on dividends and other distributions on equity paid by our operating subsidiaries, and limitations on their ability to pay dividends to us could adversely impact shareholders’ ability to receive dividends on our ordinary shares.

Dividends and other distributions on equity paid by our operating subsidiaries are our principal source for cash in order for us to be able to pay any dividends and other cash distributions to our shareholders. As of the date hereof, we have not paid any cash dividends on our ordinary shares. The instruments governing the debt of the Company, our main operating subsidiary, restrict its ability to pay dividends, with the effect of adversely impacting our shareholders’ ability to receive dividends on our ordinary shares in the foreseeable future.

If securities or industry analysts do not publish or cease publishing research or reports about our company, our business, or our market, or if they change their recommendations regarding our ordinary shares adversely, the price and trading volume of our ordinary shares could decline.

The trading market for our ordinary shares will be influenced by the research and reports that industry or securities analysts may publish about our company, our business, our market, or our competitors. Securities and industry analysts do not currently, and may never, publish research on our company. If no securities or industry analysts commence coverage of our company, our share price and trading volume would likely be negatively impacted. If any of the analysts who may cover our company change their recommendation regarding our shares adversely, or provide more favorable relative recommendations about our competitors, the price of our ordinary shares would likely decline. If any analyst who may cover our company were to cease coverage of our company or fail to regularly publish reports on our company, we could lose visibility in the financial markets, which in turn could cause our share price or trading volume to decline.

The liquidity in our securities may be limited and the market price of our securities may be volatile and decline.

The liquidity in our securities may be limited, negatively affecting the trading price of our securities. Even if an active market for our securities develops and continues, the trading price of our securities could be volatile and subject to wide fluctuations in response to various factors, some of which are beyond our control. Any of the factors listed below 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. In such circumstances, the trading price of our securities may not recover and may experience a further decline.

Factors affecting the trading price of our securities may include:

•

actual or anticipated fluctuations in our periodic financial results or the financial results of companies perceived to be similar to ours;

•

our liquidity constraints and our restructuring efforts and results;

•

our entering into an extrajudicial or a judicially-supervised reorganization;

•

expectations with respect to, and the results of, the ongoing investigations of the Brazilian tax and criminal authorities related to the Company and certain former affiliates;

•

changes in the market’s expectations about our operating results;

•

success of competitors;

•

our operating results failing to meet the expectation of securities analysts or investors in a particular period;

•

changes in financial estimates and recommendations by securities analysts concerning our company or our industry in general;

•

operating and share price performance of other companies that investors deem comparable to ours;

•

changes in laws and regulations affecting our business;

•

our ability to meet compliance requirements;

•

commencement of, or involvement in, litigation involving us;

•

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

•

the volume of our ordinary shares available for public sale;

•

any major change in our board of directors or management;

•

sales of substantial amounts of our ordinary shares by our directors, executive officers or significant shareholders or the perception that such sales could occur; and

•

general economic and political conditions such as recessions, interest rates, fuel prices, international currency fluctuations and acts of war or terrorism.

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 NASDAQ 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 shares, and of our securities, may not be predictable. A loss of investor confidence in the market for travel-related securities or the shares of other companies which investors perceive to be similar to ours could depress our share price regardless of 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 our ability to obtain additional financing in the future.

There is no guarantee that our ordinary shares will continue to qualify for listing on the NASDAQ for any period of time, and the failure to have our ordinary shares listed for any reason may negatively affect the value of our ordinary shares.

Our ordinary shares began trading on the NASDAQ on December 22, 2017. There are no guarantees that our ordinary shares will continue to qualify for listing on the NASDAQ. If our ordinary shares are ever in the future delisted, the holders could face significant consequences, including:

•

a limited availability for market quotations for our securities;

•

reduced liquidity with respect to our securities;

•

a determination that our securities are a “penny stock,” which will require brokers trading in those securities to adhere to more stringent rules and possibly result in a reduced level of trading activity in the secondary trading market for those securities;

•

limited amount of news and analyst coverage for our company in the United States; and

•

a decreased ability to issue additional securities or obtain additional financing in the future.

You will have limited ability to bring an action against us or our directors and officers, or to enforce a judgment against us or them, because we are incorporated in the Cayman Islands, because we conduct a majority of our operations in Brazil and because a majority of our directors and officers reside outside the United States.

We are incorporated in the Cayman Islands and conduct our operations in Brazil. All of our assets are located outside the United States. A majority of our officers and directors reside outside the United States and a substantial portion of the assets of those persons are located outside of the United States. As a result, it could be difficult or impossible for you to bring an action against our company or against these individuals in the Cayman Islands or in Brazil in the event that you believe that your rights have been infringed under the applicable securities laws or otherwise. Even if you are successful in bringing an action of this kind, the laws of the Cayman Islands and of Brazil could render you unable to enforce a judgment against our assets or the assets of our directors and officers.

Shareholders of Cayman Islands exempted companies such as our company have no general rights under Cayman Islands law to inspect corporate records and accounts or to obtain copies of lists of shareholders of these companies. Our directors have discretion under Cayman Islands law to determine whether or not, and under what conditions, our corporate records could be inspected by our shareholders, but are not obliged to make them available to our shareholders. This could make it more difficult for you to obtain the information needed to establish any facts necessary for a shareholder motion or to solicit proxies from other shareholders in connection with a proxy contest.

As a result of all of the above, public shareholders might have more difficulty in protecting their interests in the face of actions taken by management, members of the board of directors or controlling shareholders than they would as public shareholders of a U.S. company.

A. History and Development of the Company

Overview

Our company was founded in 1999 as a company initially focused on the development of landfills fornon-hazardous residues in the State of São Paulo. In 2000, we began operating our first landfill, CGR Paulínia, in the city of Paulínia, State of São Paulo, which, at that time, had a daily handling capacity of 500 metric tons ofnon-hazardous residues. In 2001, we developed our second landfill, CDR Pedreira—Centro de Disposição de Resíduos (“CDR Pedreira”), in the city of São Paulo, which we later sold in 2014, as more fully described below.

In 2005, we established Estação Ecologia and began recycling construction materials, and in 2006, we began the collection of biogas in CGR Paulínia. In 2007 we acquired Oxil, a company focused on the recycling and reassembling of electronics.

In 2008, Estre Petróleo e Gás Ltda. (“Estre Petróleo”) began its operations in renting and supplying oil rigs for the oil and gas industry and providing other services, such as the completion, restoration, deepening and cleaning of, as well as water injection into, oil and gas wells. That same year, we acquired Pollydutos, a company that installs and provides maintenance services for petroleum pipelines and ducts, and transports oil, gas and other fuels. We later transferred these businesses to Mr. Wilson Quintella Filho in 2014, as described below.

In 2009, we acquired, together with Angra, the hazardous andnon-hazardous waste treatment and disposal businesses in the states of São Paulo and Paraná of Veolia, a multinational waste management company based in France, which businesses would later be merged into Resicontrol Soluções Ambientais S.A. (“Resicontrol”), one of our wholly-owned subsidiary.

In 2010, we began operating (i) CTR Itaboraí, a landfill in the city of Itaboraí, State of Rio de Janeiro, of which we at the time owned 50%; (ii) CGR Curitiba, a landfill in the city of Curitiba, State of Paraná; and (iii) Doña Juana, a landfill operated as a public concession in the city of Bogotá, Colombia. In addition, in 2010, we established a partnership with Sabesp, a mixed capital, state-controlled company that provides water and sewage services to the 364 municipalities in the State of São Paulo, to implement and operate anon-domestic wastewater treatment plant, which plant started operating in 2014.

In 2011, we acquired Cavo Serviços e Saneamento (“Cavo”), from the Brazilian conglomerate Camargo Correa S.A. As a result of this acquisition, we acquired control of Cavo’s subsidiary Unidade de Tratamento de Resíduos—UTR S.A., a 50% equity interest in Essencis S.A. (“Essencis”) and a 37.6% equity stake in Logística Ambiental de São Paulo (“Loga”), thereby more than doubling our revenues. The transaction was structured and financed by Banco BTG Pactual S.A. as a 100% leveragedbuy-out. Through this acquisition, we expanded our operations to include urban waste collection and medical waste management.

In October 2011, BTG Pactual, indirectly through its vehicle BPMB Digama Participações S.A., converted all the convertible debentures issued by us which were then held by BTG Pactual into 16,818,904 of the Company’s common shares, then representing 20.9% of our capital stock. On the same date, Angra indirectly acquired 6,526,378 of the Company’s common shares, then representing 8.11% of our capital stock, in exchange for Angra’s 50% equity stake in Resicontrol. BTG Pactual and Angra introduced enhanced corporate governance and focused on improving operational efficiencies, including through the implementation of several measures with the objective of streamlining our operations.

In December 2011, Wilson Ferro de Lara became a shareholder in our company through the acquisition of 3,477,501 of the Company’s common shares from Wilson Quintella Filho, and 755,391 of the Company’s common shares then held by Gisele Mara de Moraes, then collectively representing 5.26% of our capital stock.

In 2011, our current CEO, Sergio Pedreiro, was appointed a member of our board of directors. Since then, Mr. Pedreiro has become intimately familiar with ourday-to-day operations, and has played a leading role in implementing efforts at improving our governance structure, operational efficiencies and streamlining our operations.

In 2012, we acquired: (i) full control of CTR Itaboraí by purchasing the remaining 50% equity interest in that entity that we did not then own; (ii) 100% of the shares of Viva Ambiental e Serviços S.A. and its subsidiaries (“Viva”), which provided landfill and collection services and other urban waste services predominantly in the northeastern region of Brazil; (iii) an additional 43% equity stake in Soma, which provides cleaning services in the eastern and southern regions of the city of São Paulo, thus increasing our ownership interest from 39% to 82%; (iv) 100% of the shares of Geo Vision Soluções Ambientais e Energia S.A. (“Geo Vision”), which provides landfill and collection services and other urban waste services predominantly in the State of São Paulo; (v) a 50% equity stake in our Guatapará and Jardinópolis landfills; (vi) an indirect 10.9% equity stake in Advanced Disposal Services Inc., or ADS, which provides collection, transportation, treatment, recycling and waste disposal services in the United States and which was later sold to an affiliate of BTG in 2013; (vii) a 100% stake in Ambiental Sul Brasil—Central Regional de Tratamento de Resíduos Ltda., which owns a landfill in the municipality of Sarandi, in the State of Paraná; and (viii) a 50% equity interest in Metropolitana Serviços Ambientais Ltda., apre-operational company that owns property in the State of Goiás, and has an environmental license to build a landfill with an expected daily handling capacity of 1,200 tons.

In September 2014, we executed, together with Wilson Quintella Filho, our founding shareholder, anon-cash share exchange agreement pursuant to which Mr. Quintella exchanged 2,053,983 of his common shares in our company (corresponding to 1.9% of the total common shares he then owned with a book value of R$37.4 million) for 53,701,027 common shares issued by Estre O&G, which we held at the time. Prior to this sale, Estre O&G was a 100%-owned consolidated subsidiary of ours engaged in providing tank cleaning, oil sludge treatment, pipeline construction and maintenance services in various locations under agreements entered into with Petrobras. Upon the closing of the transaction in January 2015, we ceased to hold any equity ownership in Estre O&G or any of its subsidiaries, including Pollydutos, and Mr. Quintella became holder of all the shares of Estre O&G and controller of its subsidiaries. For more information, see “—Sale of Estre Óleo e Gás Holding S.A.” below.

In December 2014, we sold our 50% equity stake in Essencis to Solvi Participações S.A. (“Solvi”), for R$488.0 million thereby increasing Solvi’s ownership to 100%. In connection with Essencis’s sale, we agreed with Solvi to terminate the arbitration proceeding regarding the sale of Essencis’ shares by Camargo Correa S.A. to us.

In October 2014, we sold 65% of our equity interest in CDR Pedreira to BTG Pactual (through BTG Pactual’s vehicle A.Z.P.S.P.E.) for a total purchase price of R$180 million paid in three instalments over the course of 2014. Simultaneously with this sale, we entered into call and put option agreements in connection with a potential repurchase of CDR Pedreira from A.Z.P.S.P.E., originally set to expire in October 2017. On May 19, 2016, we executed a private agreement with A.Z.P.S.P.E. pursuant to which we renounced our rights under the call option and recorded a loss in connection therewith. Following this, BTG Pactual sold CDR Pedreira to an affiliate of Veolia in Brazil. For more information, see “—Sale of CDR Pedreira—Centro de Disposicâo de Resíduo” below.

In March 2015, we sold our 100% interest in Azaleia Empreendimentos e Participações S.A. (“Azaleia”), back to an affiliate of the original seller. The purpose of such transaction was to divest certain of our collections operations in the region of Ribeirão Preto conducted through Geo Vision, which we acquired in 2012. As the buyer was an entity wholly-owned by the original sellers of Geo Vision, at the time of settlement of the earnout provisions for the Azaleia transaction in 2016, we fully offset our accounts receivable from this transaction against our accounts payables in connection with the original acquisition. For more information, see “—Sale of Geo Vision Contracts through Azaleia Empreendimentos e Participacões S.A.” below.

In May 2015, Sergio Pedreiro was appointed as our interim CEO, and was appointed CEO on a permanent basis in September 2015. Under his leadership, we have implemented several concrete measures with the goal of operating at a level of sophistication and efficiency similar to that of major U.S. waste management companies. Chief among these new measures were the reorganization of our upper management team, increased focus on compliance, reduction of corporate headcount, promotion of a new results-oriented culture, and implementation of an objective, results-based compensation system.

In December 2015, we sold our 75% equity stake in Argentina-based Estrans S.A. (“Estrans”), the proceeds of which were used to offset certain existing obligations. For more information, see “—Sale of Interest in Estrans S.A.” below.

In January 2016, we entered into an agency agreement with USA Global MKT (“USA Global”), for the sale of our 51% equity stake in Colombia-based Doña Juana. Pursuant to the terms of the agreement, USA Global, our partner andco-investor in Doña Juana, assumed control of Doña Juana, while at the same time seeking a compatible buyer for our interest in Doña Juana. As per the terms of the agreement, USA Global also agreed to advance us payments for the sale of Doña Juana (irrespective of whether a buyer was found or such sale was completed). For more information, see “—Sale of Interest in CGR Doña Juana S.A. ESP” below.

In an effort to return to profitability and to strengthen our balance sheet, we have been undergoing a comprehensive financial and corporate restructuring over the past several years pursuant to which we have reviewed and rationalized our cost structure, pricing, compliance and controls, planning processes, information technology and use of data. For more information, see “Item 5.A. Operating and Financial Review and Prospects—Operating Results—Key Factors Affecting Our Results of Operations—Restructuring Plan.”

On December 21, 2017, immediately prior to the Merger, we completed ourPre-Closing Restructuring, pursuant to which the holders of the Company’s common shares (other than Angra) contributed their common shares in the Company to us in exchange for an aggregate of 27,001,886 of our ordinary shares. In addition, 1,983,000 of our ordinary shares were issued to the Employee Compensation Entity immediately prior to the closing of the Merger.

As a result of ourPre-Closing Restructuring and the Merger, the Company and Estre USA became the Registrant’spartially-owned subsidiaries, and the former public security holders of Estre USA became our shareholders.

On December 21, 2017, we completed the Merger pursuant to which Merger Sub merged with and into Estre USA.

On December 21, 2017, the Registrant issued 15,438,000 of the Registrant’s ordinary shares and 3,748,600 warrants to purchase the Registrant’s ordinary shares at US$11.50 per share to certain institutional investors unaffiliated with us pursuant to a private investment in public equity, which we refer to as the PIPE Investment.

On December 26, 2017, we completed our Debt Restructuring, pursuant to which we used an amount of US$110.6 million from the total cash investments received by us to partially prepay certain of our existing debentures and related debt acknowledgment instrument, each denominated in Brazilian reais, coupled with a partial debt write-down and the refinancing of the balance of our existing debentures and related debt acknowledgment instrument through the amendment and restatement of such instruments with new terms.

Our ordinary shares and warrants began trading on the NASDAQ on December 22, 2017 under the symbols “ESTR” and “ESTRW,” respectively.

On March 6, 2018, Angra confirmed the exercise of its put option to sell all of its shares to the Company through a formal notification. Consequently, on March 6, 2018, Angra transferred 8,871,895 shares to the Company, with the Company having until September 6, 2018 to complete the payment for such shares. The shares transferred by Angra are currently held by the Company as treasury shares and, thus, in accordance with Brazilian Law No. 6,404/76, will not hold voting or dividend rights for as long as they remain in the treasury of the Company. As of the date of this annual report, as a result of our liquidity constraints, we have not yet made any payments to Angra with respect to the share transfer, but are negotiating alternative payment terms with Angra.

On April 23, 2018, we concluded the sale of our 50% interest in Leccaros Participações S.A. (“Leccaros”) for R$22.1 million to a third party—Lara Central de Tratamento de Resíduos Ltda. Lecarros owned a single asset consisting of land located in the state of São Paulo and did not have any operations. Cash consideration of R$10.0 million was received upon the closing of the transaction, and R$12.1 million are payable in 12 equal monthly installment payments.

On December 14, 2018, we concluded the sale of our 50% interest in CGR Catanduva – Centro de Gerenciamento de Resíduos Ltda. (“CGR Catanduva”) to our business partner for a total consideration of R$7.5 million. CGR Catanduva owned and operated a landfill in Catanduva, São Paulo State. Cash consideration of R$1.0 million was received upon closing of the transaction, a second payment of R$4.0 million was received on December 18, 2018 and R$2.5 million will be received in 5 equal monthly installment payments between January 2019 and May 2019. As a consequence of the sale of our 50% interest in CGR Catanduva its results are no longer consolidated with ours. As of December 31, 2018, the net assets of CGR Catanduva were R$10.2 million, with R$5.1 million attributable to us. The transaction resulted in a gain on sale of R$2.0 million.

Recent Divestments and Acquisitions

Sale of Interest in CGR Doña Juana S.A. ESP

On January 5, 2016, we entered into an agency agreement with USA Global, for the sale of our 51% interest in Doña Juana, based in Colombia. Pursuant to the terms of the agreement, USA Global, our partner andco-investor in Doña Juana, assumed control over Doña Juana while at the same time seeking a compatible buyer for our interest in Doña Juana. As per the terms of the agreement, USA Global also agreed to advance payments to us for the sale of Doña Juana (irrespective of whether a buyer was found or such sale was completed). After USA Global made the first payment to us for Doña Juana, the composition of Doña Juana’s management completely changed such that we relinquished all control over the entity. Accordingly, all of the Estre-appointed board members and executive officers of Doña Juana resigned and were replaced by individuals appointed by USA Global, thus effectively fully conveying control over Doña Juana to USA Global. The initial term of this agency agreement was 18 months, which was subsequently extended by 12 months, during which time we received 59.6% of the purchase price for Doña Juana of US$1.9 million (or R$6.2 million, calculated based on an exchange rate of $1 to R$3.2591 for payments received in 2016 and based on a the actual exchange rate existing on the day of payment for all payments made in 2017) from USA Global in four installments over the course of 2016. In February 2018, we signed an amendment to the agency agreement postponing some of USA Global’s obligations, such as (i) extending the date that the final installment of US$0.6 million (R$2.1 million, calculated as of February 28,2018) would be paid on May, 26, 2018 and (ii) extending the contract term from 12 to 14 months. As of the date of this annual report, USA Global has remaining payment obligations in an amount of US$0.8 million (R$2.8 million, calculated using the average FX rate from January 1 to November 30, 2018) to be paid in installments until June 2019, as described below.

On November 20, 2018, we fully transferred our shares in Doña Juana to Ecensa Colombia, a subsidiary of USA Global, but continue to have an outstanding balance of receivables in the amount of R$2.8 million as of December 31, 2018 that is payable by USA Global.

Doña Juana operates pursuant to a contract with the municipality of Bogotá and, as such, must have authorization of the Colombian regulatory authority UAESP—AESP—Unidad Administrativa Especial de Servicios Publicos (“UASEP”), in order to operate and also to effect certain changes, including, prior to April 30, 2018, a change in the shareholder composition. On April 30, 2018, UAESP amended the contract with Doña Juana to modify the required procedures to effect a change in shareholder structure such that Doña Juana must only now notify UASEP about shareholder changes rather than obtaining UASEP’s prior approval and such change permitted the transfer of shares to occur.

Following the execution of the original agency agreement with Doña Juana, we classified our investment in Doña Juana as an asset held for sale, recording it at its carrying amount. After the investment in Doña Juana was classified as an asset held for sale, we accounted for the investment under the equity method under IAS 28. In 2017, our share of profit in Doña Juana amounted to approximately R$0.7 million.

On November 20, 2018, we fully transferred our shares in Doña Juana to Ecensa Colombia, a subsidiary of USA Global and agreed that the outstanding amount to be paid to us (as described above) is paid in five installments between December 2018 and June 2019. Such transaction increased our profits by R$31.7 million as a consequence of the reversal of a provision for losses on investments. As of May 5, 2019, the remaining balance of R$1.6 million is scheduled to be paid between May 31 and June 28, 2019.

For additional information, see notes 1.3.1 and 10.2.1. to our audited financial statements included elsewhere in this annual report.

Sale of Geo Vision Contracts through Azaleia Empreendimentos e Participacões S.A.

On May 5, 2015, we entered into a purchase and sale agreement to sell 100% of our interest in Azaleia to Limpus—Soluções Ambientais Ltda. (“Limpus”) for R$30.3 million. The purpose of such transaction was to divest certain of our smaller collections operations in the region of Ribeirao Preto conducted through Geo Vision Soluções Ambientais e Energia S.A. (“Geo Vision”), which we acquired in 2012. These collections operations generated low revenues relative to associated costs, particularly considering the sizeable distance between the collection sites and our landfills. As a result, as part of our restructuring process and with the goal of streamlining our operations in the region, wespun-off these collections operations into Azaleia, a newly-formed entity, which we later sold to Limpus, an entity that was controlled by the original sellers of Geo Vision. Following the execution of our agreement with Limpus in May 2015, we ceased to record results from these contracts. In the first part of 2015 prior to the sale of Azaleia, generated revenues of R$10.9 million and operating costs of R$9.2 million.

There was no cash exchanged as part of the Azaleia transaction. In connection with the original acquisition of Geo Vision, we had a remaining balance of R$39.8 million to be paid to the seller as of December 31, 2016. As Limpus was an entity wholly-owned by the original sellers of Geo Vision, at the time of settlement of the earnout provisions for the Azaleia transaction in 2016, we fully offset our accounts receivable from this transaction, amounting to R$41.3 million as of December 31, 2016, as adjusted by interest, by our accounts payable on the original Geo Vision of transaction of R$39.8 million, as adjusted for interest, with the remaining balance of R$1.4 million written off as a loss from the settlement of accounts.

For additional information, see note 1.3.2 of our audited financial statements included elsewhere in this annual report.

Sale of CDR Pedreira—Centro de Disposicâo de Resíduos

In October 2014, we entered into a purchase and sale agreement with BTG Pactual (through AZPSPE) for the sale of 65% of CDR Pedreira for a total purchase price of R$180 million paid in three installments over the course of 2014.

In addition, simultaneous with this sale, we entered into call and put option agreements in connection with our potential repurchase of CDR Pedreira from AZPSPE, originally set to expire in October 2017. The call and put option amount was R$180 million, plus 25% fixed interest per year from October 2014 and an additional put option premium equivalent to R$1.00 per share. The put option premium would be due on the earlier of (i) the exercise date of the put option or (ii) the last day of the period to exercise the put option. The fair value of the call option was R$20.9 million and R$10.7 million as of December 31, 2016 and 2015, respectively, recorded in noncurrent assets against other operating income. Despite the call option, following our execution of the purchase and sale agreement in October 2014, we ceased all control and influence in the operation and management of CDR Pedreira.

On May 19, 2016, in connection with the sale by BTG Pactual (through AZSPE) of the CDR Pedreira to an independent third party, we agreed to terminate the right corresponding to the call and put options, the fair value of which totaled R$20.8 million at that time and, accordingly, fully wrote it off as a loss under “Other Operating Expense” in 2016.

Transfer of Interests in Loga, Attend and Terrestre

We recorded the transactions as a distribution to shareholders of equity in the amount of R$103.2 million in the year ended December 31, 2017 corresponding to the carrying amount of these investments and the account receivable.

Sale of Interest in Leccaros Participações S.A.

On April 23, 2018, we concluded the sale of our 50% interest in Leccaros Participações S.A., anon-operational company holding only real estate assets, for R$22.1 million to a third party—Lara Central de Tratamento de Resíduos Ltda. Cash consideration of R$10.0 million was received upon closing of the transaction, and R$12.1 million was payable in 12 equal monthly installment payments. As of December 31, 2017, Leccaros’ net assets were R$6.5 million, with R$3.3 million attributable to us. The transaction resulted in a gain on sale of R$37.6 million, of which R$18.8 million was attributable to us. As of December 31, 2017, we classified our investment in Leccaros as an asset held for sale. For additional information, see note 1.3.5 of our audited financial statements included elsewhere in this annual report.

Sale of Catanduva

On December 14, 2018, we concluded the sale of our 50% interest in CGR Catanduva – Centro de Gerenciamento de Resíduos Ltda., an invested company which owned and operated a landfill in Catanduva, São Paulo State, for R$7.5 million to our business partner – SHZ Participações Ltda. Cash consideration of R$5.0 million was received upon closing of the transaction and R$2.5 million is payable in 5 equal monthly installments (of R$0.5 million each). As of December 31, 2018, the net assets of CGR Catanduva were R$10.2 million, with R$5.1 million attributable to us. The transaction resulted in a gain on sale of R$2.0 million.

Sale of Energy Business

As per our financial statements as of and for the year ended December 31, 2018, our energy business is considered an assetheld-for-sale. The sale of the energy business has been approved by our board of directors and we are in ongoing discussions with potential buyers. However, as a significant asset, the energy business is part of the collateral securing our obligations under the Debt Instruments and, therefore, the transaction is subject to the approval of the holders of our Debt Instruments, which approval remains pending. For additional information, see note 1.3.1 of our audited financial statements included elsewhere in this annual report.

Other Pending Divestments

As described elsewhere in this annual report, in light of our severe liquidity constraints, we are analyzing and exploring the potential sale of additional assets to improve our liquidity position in the future. However, as of the date of this annual report, we have not entered into any memoranda of understanding or binding commitments in relation to the sale of any assets not disclosed elsewhere in this annual report.

Capital Expenditures

Historically, we have allocated our capital expenditures by balancing replacement and growth needs and expect to continue to do so.

In 2018, we spent R$122.1 million on capital expenditures, representing 9.7% of our revenue from services rendered, of which R$51.3 million was spent on land and implementation of cells on our landfills, R$25.1 million was spent on turbines for ourgas-to-landfill energy business and MRF equipment, and R$47.7 million was spent on the acquisition of new operating equipment.

In 2017, we spent R$145.0 million on capital expenditures, representing 10.8% of our revenue from services rendered, of which R$57.2 million was spent on land and implementation of cells on our landfills, R$35.6 million was spent on turbines for ourgas-to-landfill energy business and MRF equipment, and R$13.8 million was spent on the acquisition of new operating equipment.

B. Business Overview

Description of Our Operations

We provide collection, transfer, recycling and disposal services to more than 31 million people. We provide municipal, commercial and industrial customers with a full range of waste management solutions, with a focus on leveraging our strategic disposal network to capture compelling growth opportunities in the Brazilian waste management industry. With the goal of creating and maintaining vertically integrated operations, we seek to serve the waste management needs of our customers from the point of collection to the point of disposal, a process we refer to as internalization. By internalizing the waste in the markets in which we operate, we strive to capture higher operating margins while simultaneously attaining a stable revenue stream, with the overall effect of creating significant barriers to entry for competitors.

As of December 31, 2018, we operated the largest landfill portfolio in Brazil, comprised of 12 landfills fornon-hazardous residues (Class IIA and IIB) and three landfills also handling hazardous residues (Class I). In 2018, we handled over 17,441 daily tons of waste and, as of December 31, 2018, our landfills had a combined remaining licensed capacity of approximately 129.2 million cubic meters, with a robust pipeline of 24.2 million cubic meters of additional unlicensed capacity. Our waste management infrastructure also includes three autoclaving facilities for the treatment and disposal of medical waste, five transfer stations, two units for blending hazardous waste, one refuse-derived fuel (RDF) facility, one electronic recycling plant (REEE), three landfillgas-to-energy facilities containing a total of 13 electricity generators with an aggregate 18.5 MW of installed capacity, two leachate treatment facilities and a fleet of 1,539 vehicles supporting our collection, O&G, medical waste and landfill businesses.

Our geographic focus is on densely populated urban markets where we can capitalize on upstream and downstream opportunities for vertical integration through a strategically-planned and high-qualitylandfill-infrastructure. The states in which we operate represent approximately 45.3% of the population and 55.2% of the GDP of Brazil, according to IBGE.

The map of Brazil below demonstrates our geographic footprint and our capabilities in the main markets in which we operate as of December 2018.

Brazil is geographically similar in size to the continental United States, and we believe the Brazilian waste management market exhibits many of the same characteristics as the U.S. market 30 years ago. There are 2,976 landfills in Brazil as of June 2017, according to the International Solid Waste Association (“ISWA”) and ABRELPE, of which approximately 25% are duly licensed and comply with regulatory and environmental standards and the remaining 75% are open dumps that are considered illegal. By contrast, there are approximately 1,700 landfills in the United States as of December 31, 2018, as compared with 7,924 in 1988 when the enforcement of the Resource Conservation and Recovery Act and other environmental regulations had begun to solidify. In addition, close to one half of all MSW in Brazil, or 29 million tons annually, is not properly disposed of according to ABRELPE.

We are a significant participant in a fragmented industry. In the Brazilian landfills market, we have a 14.7% market share, with the top five players capturing 42.4% of the total market, according to our analysis based on the most recent ABRELPE data available from 2017. Starting in 2018, we began to measure landfills market share on the volume effectively disposed of in the relevant landfills. We understand that participation in the total volume disposed of in landfills is a good indicator of landfills market share. The graph below demonstrates our market share relative to our main competitors as of 2017:

We have been undergoing a comprehensive financial and corporate restructuring over the past several years pursuant to which we have reviewed and rationalized our cost structure, pricing, compliance and controls, planning processes, information technology and use of data. This restructuring effort has yielded several tangible benefits through focus on the following initiatives, among others; (i) the comprehensive redesign of our management information systems, including migration to SAP and implementation of CRM Oracle solutions and pricing systems, with the effect of improving efficiency of pricing and internal controls; (ii) the sale of certain assets that negatively impacted our margins and did not align with our strategic vision, (iii) collection of overdue accounts and implementation of price adjustments on certain large contracts with our municipal customers and (iv) the reduction of corporate headcount by approximately 13% in December 2018.

We have been facing liquidity issues as further described in this annual report and are focused on executing a number of initiatives to allow us to improve our liquidity position and return to profitability and growth, including, among others: (i) the sale of our energy business (which, prior to its classification as a discontinued operation, was part of the Value Recovery segment), (ii) the development of new landfills, with three greenfield landfill projects in Brazil in the pipeline, (iii) commercial efforts to attract new C&I customers to our existing landfills, and (iv) the development of new transfer stations to expand the coverage area of our existing waste disposal infrastructure.

Business Segments

We offer our customers a full range of waste-related and environmental services that comprise every step of the waste management cycle, from waste collection to disposal and, ultimately, value recovery. Our operations are grouped into four distinct business segments (i) Collection & Cleaning Services; (ii) Landfills; (iii) Oil & Gas; and (iv) Value Recovery.

Collection & Cleaning Services

Our Collection & Cleaning Services segment is our largest in terms of revenues, comprising 69.0% of our total net revenues from services rendered in 2017 and 68.4% in 2018. This segment includes, primarily, household collection, pursuant to exclusive contracts with municipalities across six Brazilian states. Our collection services are supported by a fleet of 864 vehicles (845 for municipal services and 19 for C&I services) as of December 31, 2018 (of which 569 were owned by us, and 295 were leased), consisting mostly of collection and transfer trucks. According to census data compiled by the IBGE, we estimate that we currently serve approximately 31 million residential clients through our collection and cleaning and landfill activities and 580 private clients through our collection and cleaning activities.

A significant portion of our revenues in this segment is derived from urban cleaning services, including street sweeping and the maintenance of public spaces and monuments. Through Soma, we operate (together with other providers) the largest urban cleaning operation in Brazil for the city of São Paulo. As described elsewhere in this annual report, following a recent bid process or the city of São Paulo, the Company was not the bidder with the lowest price for any of the six parcels in São Paulo and, on May 2, 2019, we were informed that our emergency contract with the municipality of São Paulo will be terminated on June 1, 2019, at which point we will no longer provide services in São Paulo.

This segment involves focused logistical planning in terms of routing based on the profiles and conditions of each municipality, with the objective of optimizing efficiency and minimizing risks and environmental impact in transporting waste to the final destination. In 2018, approximately 56.0% of the MSW we collected through this segment was subsequently disposed in our own landfills, as compared to 55.0% in 2017.

Public Sector Collections and Cleaning Operations

Our residential collection operations consist of curbside collection of residential solid waste from trash bins, small carts or containers for transport to a transfer station/disposal site or landfill. These services are typically performed pursuant to exclusive contracts with municipal entities that are usually entered into for an initial term of three to five years. Our municipal contracts typically set forth fees based on the weight of the waste collected or, less commonly, a fixed monthly collection fee, as is the case for our Salvador contract. The pricing of these contracts is established at the time of execution as part of the competitive bidding process based on factors such as anticipated collection frequency, type of collection equipment furnished, number of employees needed to provide service, anticipated type and volume or weight of the waste collected, distance to the transfer station or disposal facilities and our disposal costs. The majority of contracts with our customers have annual price escalation clauses that are tied to inflation. Contracts with municipalities in the Collection & Cleaning segment may be renewed or extended at the end of the scheduled term.

Our urban cleaning services are typically bundled with our collections operations. Services consist mainly of street sweeping services operations comprised of manual or mechanized sweeping to maintain public roads and streets cleaned on aday-to-day basis, including the washing and disinfection of streets and public places following the conclusion of certain activities, such as outdoor public markets. In addition, we also provide public cleaning services that entail the washing of public equipment and monuments, mechanized scraping of land and sand from the gutters of public roads, weeding and scrubbing of streets and roadways, collecting and transporting bulky debris such as rubble. We also have specialized teams dedicated toward cleaning and sweeping after special events and for temporary operations. Finally, we provide manual and mechanized cleaning of beaches, coastlines, streams and channels as part of our municipal cleaning activities.

We operate exclusive waste collection services in some of the largest and most densely-populated urban areas in Brazil such as the cities of São Paulo and Curitiba, which had a combined metropolitan population of approximately 24 million inhabitants in 2018 according to IBGE. For additional information regarding our contracts with the city of São Paulo and Curitiba, see “—Our contract with the municipality of São Paulo” and “—Our contract with the municipality of Curitiba”. In the state of São Paulo, we provide collection services to the cities of Ribeirão Preto, Taboão da Serra, Araraquara, Jaú, Américo Brasiliense and Sertãozinho and elsewhere in Brazil, in the cities of Maceió in the state Alagoas, Aracaju in the state of Sergipe and Salvador in the state of Bahia. For additional information regarding our main customers in the Collection & Cleaning Services segment, see “—Collection & Cleaning Services.”

We generally secure our contracts with municipalities through a competitive bidding process pursuant to which we receive exclusive rights to service all or a portion of the homes in the respective municipalities.

The process of public procurement in Brazil is regulated by a series of federal laws, primarily: Law No. 8,666/1993 (Competition, Price Taking, Invitation, etc.); Law No. 10,520/2002 (Trading); Law No. 8,987/1995 (Public Concession), Law No. 11,079/2004 (Contracting ofPublic-Private Partnership) and Law No. 13,303/2016(State-Owned Companies). This legislation stipulates the criteria for the competitive bidding process, which involves analysis of legal, tax, technical and financial qualifications and, most critically, pricing, with municipalities typically favoring price competitiveness above other factors. In Brazil, it is generally the responsibility of the municipality to render collection services and, therefore, the municipality is obliged to adhere to a competitive bidding process in contracting these services to private entities as per Articles 37 and 175 of the Federal Constitution of 1988, item XXI.

Revenue from our municipal collections operations consists of the fees we receive from our customers, with pricing of these contracts established based on factors such as anticipated collection frequency, type of collection equipment furnished, anticipated type, distance to the transfer station or disposal facilities and, occasionally, also include disposal costs. In 2018, our revenues from collections services from municipal contracts represented 97.8% of our total net revenues from services in our Collection & Cleaning segment and 56.3% of our total net revenues from services on a company-wide basis (compared to 89.5% and 60.9%, respectively, in 2017).

Commercial and Industrial Collections Business

While the Brazilian constitution establishes that municipalities are responsible for providing waste collection services to its citizens, each municipality has discretion to establish maximum per capita waste volumes entitled to collection, with any excess amount falling outside the purview of the constitutional protections. In the City of São Paulo, for example, individuals that generate more than 200 liters (equivalent to approximately 50 kilograms) of waste daily are not eligible for the collection services rendered by the concessionaires Loga and Ecourbis and have to hire private collection companies. In this context, C&I collection businesses have developed significantly in Brazil to fill the gap for large waste generators.

We offer comprehensive waste management solutions to our C&I customers that encompass the entire waste management chain, including strategic planning for our customers’ waste management needs with the goal of optimizing operational and economic efficiency. We provide diagnostic and waste classification services to our C&I customers based on the types and quantities of waste generated, which is then used in order to map out the disposal strategies available. We also offer waste handling services to our C&I customers, whereby we supply waste containers suitable for our customers’ needs and transports the waste from where it is generated to the central collection areas within the customer’s premises where the waste containers and compactors are located. Our C&I collection and transportation services involve planning the best routes and vehicles suitable for waste collection and disposal, and collecting the waste from the customers’ premises and transporting it to its final destination.

Standard service agreements with C&I customers are typically one year in duration with pricing based on estimated weight and time required to service the account. In 2018, revenues from collections and cleaning services from C&I customers represented 7.5% of our total net revenues from services on a company-wide basis (compared to 7.2%, respectively, in 2017).

We have observed a growth in demand for our C&I services in recent years as part of companies’ efforts to comply with the requirements of Brazil’s National Solid Waste Policy legislation of 2010, particularly in relation to treatment services. In order to meet such demand, we have established a dedicated subdivision specifically focused on capturing and servicing C&I business opportunities. We intend to focus our marketing efforts in the short-term on capturing new customers in the manufacturing, food & beverage, vehicle assembly, metallurgy and steelmaking sectors.

Principal Customers in Collections and Cleaning Segment

We rely significantly on municipal customers within our Collection & Cleaning segment as a source of revenues. Contracts with municipal customers and subject to competitive bidding processes, as such are inherently subject to a high degree of uncertainty, and there can be no guarantee that past practices will be indicative of future success. Accordingly, we cannot predict with certainty when the competitive bidding processes for municipal contracts occur and, likewise, there can be no assurances that we will prevail in securing municipal contracts on favorable terms or at all. Our most significant contracts in the Collection & Cleaning segment are our contracts with the municipalities of São Paulo and Curitiba. Together, our contracts with the municipalities of São Paulo and Curitiba represented 79.0% of the net revenues from services rendered for the Collection & Cleaning segment for the year ended December 31, 2018, and 39.9% of our total net revenues from services during the same period. The contract with the municipality of São Paulo is currently serviced on an emergency basis and on May 2, 2019, we were informed that our emergency contract with the municipality of São Paulo will be terminated on June 1, 2019, at which point we will no longer provide services in São Paulo. The contract with the municipality of Curitiba was renewed in January 2019 for an additional5-year period.

Our contract with the municipality of São Paulo

We have been servicing the São Paulo contract through Soma since 2011. Our contract with the municipality of São Paulo for urban cleaning and street sweeping services comprised approximately 25.5% of our revenues in 2018 (29.1% of our revenues in 2017). This contract expired, and we are currently providing urban cleaning services to the city of São Paulo pursuant to a temporary contract. The temporary contract was first entered into on December 15, 2017 and expired in June 2018. On June 12, 2018, we further extended the temporary contract until the end of 2018. In December 2018, we signed a new extension of the contract which was set to expire in June 2019, subject to earlier termination by the municipality. However, the extended temporary contract executed in June 2018 introduced certain significant changes to the contractual arrangement. Most significantly, under the extended temporary contract, the city of São Paulo has been divided into six separate parcels for urban cleaning, whereas under the prior contract the city had been divided into two parcels only. We, through Soma, were awarded only two parcels under the extended temporary contract, which reflects a significant decrease of our service area, since we previously serviced one of the only two parcels. As a result of these changes, the monthly revenue under the extended temporary contract decreased by 37.7%.

After a series of delays, a new bid for the São Paulo contract was initiated in October 2018, in which the Company participated. In connection with the bidding process, São Paulo has divided the urban cleaning contract into six separate parcels, in line with the extended temporary contracts entered into in June 2018. The Company was not the bidder with the lowest price for any of the six parcels in São Paulo and, on May 2, 2019, we were informed that our emergency contract with the municipality of São Paulo will be terminated on June 1, 2019, at which point we will no longer provide services in São Paulo. For additional information regarding the risks of losing the contract with the municipality of São Paulo, see “Item 3. Key Information—D. Risk Factors—A significant portion of our revenue is derived from a small number of customers, and partial or full loss of revenues from any such customer may adversely affect our revenues and results of operations. In particular, the municipality of São Paulo is currently serviced based on a short-term temporary contract which will end on June 1, 2019. The loss of business from the São Paulo contract will have a material adverse impact on us—Our contract with the municipality of São Paulo.”

Our contract with the municipality of Curitiba

Cavo, which we acquired in 2011, has been servicing the Curitiba contract since 1995. Our contract with the municipality of Curitiba for collections, urban cleaning and street cleaning comprised approximately 12.0% of the Company’s revenues in 2018 (12.5% in 2017). In October 2018, we won the competitive bidding process for the Curitiba collections and cleaning contract. We signed afive-year contract on January 3, 2019 with a maximum value of R$844.8 million (a reduction in price of approximately 14.1% compared with the previous contract) and are currently providing the contractual services to Curitiba.

For additional information regarding the competitive bidding processes in Curitiba and São Paulo, see “Item 5.A. Operating and Financial Review and Prospects—Operating Results—How We Generate Revenue—Competitive Bidding Processes and Revenue Impact.”

Other relevant Customer in the Collection and Cleaning Segment

In addition, our other significant customers in this segment include the municipalities of Ribeirão Preto, Taboão da Serra, Araraquara, Jaú, Américo Brasiliense, Sertãozinho Altinópolis and Rio Claro, all located in the State of São Paulo, Campo Largo in the state of Paraná, and the cities of Maceió in the state Alagoas, Aracaju in the state of Sergipe, and Salvador in the state of Bahia.

Our principal C&I customers in this segment are GPA, Vale, Kimberly Clark, Bosch and Votorantim.

Our Transfer Stations

As part of our vertically integrated solid waste disposal services, we operate five transfer stations. Transfer stations receive, consolidate and transfer solid waste to landfills and recycling facilities. Transfer stations enable us to:

•

increase the operational reach of our landfill operations;

•

increase the volume of revenue-generating disposal at our landfills; and

•

improve efficiency of collection, personnel and equipment.

Transfer stations provide our collection operations with a cost-effective means to consolidate waste and reduce transportation costs while providing our landfill sites with an additional point of access to extend the geographic reach of a particular landfill site with the goal of increasing market share. Our transfer stations thus provide important economies of scale, permitting us to offer more competitive pricing to municipalities even when a municipality generates a low amount of waste or is far from the ultimate landfill.

Our transfer stations are used exclusively for the temporary storage of waste we collected prior to final disposal at a landfill and, accordingly, are not used by other private and municipal haulers. Therefore, while our transfer stations serve as an integral part of our disposal network, they do not independently generate revenues through afee-based system.

Landfills

We own and operate the largest portfolio of landfills in Brazil, with 12 landfills for the final disposal of both hazardous (Class I) andnon-hazardous (Classes IIA and IIB) waste. In addition, as of December 31, 2018, we were developing three additional landfill sites, which we expect will become operational on dates ranging from late 2019 through 2020. Our landfills received approximately 6.3 million tons of waste in 2018, with a remaining licensed disposal capacity of more than 129.2 million cubic meters of waste as of December 31, 2018. In 2018, 17.0% of the total volume of waste disposed in our landfills was internalized from our municipal collection operations and transfer stations.

Landfills remain the most cost-effective waste disposal technology and the primary way of disposing of waste in Brazil, receiving approximately 59.1% of MSW collected in 2017, according to the ABRELPE. To the extent alternative treatments for industrial waste develop in Brazil (such as biological treatments, for example), this treated waste would still need to be disposed somewhere, which we believe bodes well for the longevity of a landfill-focused disposal model in Brazil. In addition, we perceive recycling as an attractive alternative to waste disposal that has the potential of adding value to the waste stream. According to ABRELPE and the EPA, less than 2% of waste collected in Brazil is recycled compared to 34.6% recycled in the United States as of December 31, 2017. As Brazil continues to develop its regulatory framework with an increased focus on recycling and other environmental sustainability strategies, we believe that higher recycling rates could have the effect of increasing the longevity of our landfills.

We believe our landfills are operated in an efficient manner, adhering to a series of requirements designed to protect the soil, groundwater, atmosphere and surrounding communities. All leachate naturally generated in our landfills is collected and treated into reclaimed water for reuse, and greenhouse gases are captured and treated so as to minimize the impact of greenhouse gases on the atmosphere. Our landfills are compliant with international environmental policies and standards, and we have never experienced a material operational disruption as a result of any environmental violation on any of our properties. We are the first company in Brazil to use drones to control and monitor the geotechnical parameters concerning the stability of each landfill. In addition, it is our policy to use an extra layer in the impermeability and drainage layer at the bottom of each installation for purposes of environmental protection. We have implemented an internal quality control and benchmarking system so as to promote consistency, as well as a high standard of quality and environmental compliance, across our operations. In fact, our landfills have been regularly rated highly by CETESB, the State of São Paulo’s environmental agency, which frequently monitors and grades the operations of landfills in that state, having most recently rated our operations between 8.3 and 10.0 on a scale of 0 to 10 (Paulínia 8.3; Itapevi 8.5; Piratininga 9.1; Guatapará 10.0; Tremembé 10.0; and Jardinópolis 10.0).

CETESB, the state environmental agency of São Paulo, developed the landfill quality index (IQR) in 1997 as a tool to evaluate the general conditions of MSW disposal in the state of São Paulo through assigning a score from 0 to 10 to all disposal sites. The scores intend to reflect the adequacy of the disposal processes at such sites from a sustainability standpoint. The rating takes into account a variety of factors, primarily, among others: (i) the site support structure, including the sufficiency of the entry and discharge points and the draining and collection systems for percolated liquid, (ii) compacting rates, (iii) soil protection systems to help reduce odor, control litter, insects, and rodents, and protect public health, (iv) rainwater drainage systems, (v) leachate collection and removal systems, (vi) groundwater monitoring to determine whether waste materials have escaped from the landfill and (vii) monitoring of landfill gas emissions. CETESB assigns a rating largely based on data compiled through reports prepared by CETESB technicians during site visits. In 2016, the average landfill score in the state of São Paulo was 8.5, according to CETESB’s 2016 Inventory of Urban Solid Waste Report (Inventário Estadual de Resíduos Sólidos Urbanos). In 2017, the average landfill score in the state of São Paulo was 8.7 according to CETESB’s State Survey of Urban Waste for the year 2017.

We focus on the operation ofmid- and large-scale landfills (i.e., landfills with greater than 100 tons per day and total area over 100 thousand square meters). Our landfills received approximately 6.3 million tons of waste in 2018 and, over the past three years, have averaged approximately six million tons of waste per year. As of December 31, 2018, our operating landfills had a remaining licensed disposal capacity of more than 129.2 million cubic meters of waste. Of the total volume of waste disposed in our landfills in 2018, 47% originated from our municipal collection operations and transfer stations. Our landfills are located in some of the largest markets in Brazil, including the state of São Paulo, which is the most populous Brazilian state. Furthermore, the landfills that we operate outside of São Paulo serve some of the fastest-growing markets in the Northeastern region of Brazil, where we believe we are well-positioned to capture an increased portion of market share in the coming years.

The map below shows the location and remaining life span of our 12 landfills and the inset shows the landfills we operate in the state of São Paulo:

LOGO

Several of our landfill sites have the potential for expanded disposal capacity beyond the currently permitted acreage. We monitor the availability of permitted disposal capacity at each of our landfills and evaluate whether to pursue an expansion at a given landfill based on estimated future waste volumes and prices, market needs, remaining capacity and the likelihood of obtaining licensing. Thein-place capacity of our landfills is subject to change based on engineering factors, requirements of regulatory authorities and our ability to continue to operate our landfills in compliance with applicable regulations and licensing restrictions.

We have observed that our landfills follow approximately the same patterns as those in the United States, insofar as it relates to the landfills’ base waterproofing system, which exhibit a clayK10-7 compacted layer, HDPE membrane and drainage system. The sizes of our landfills vary as in the same way as typical landfills in the United States. We believe that the main difference between our landfills and landfills typically found in the United States is that our landfills are designed and operated intwo-to-one (two horizontal, one vertical) slopes, while typical landfills in the United States exhibit slopes that are less steep. This characteristic results in our landfills having a higher number of waste layers, and consequently higher volume capacity, as well as significantly greater stability.

The table below sets forth key operating data with respect to each of our landfill sites, including their respective area, processing capacity and remaining licensed capacity as of December 31, 2018.

Data presented corresponds exclusively to remaining capacity for which we have already obtained a license for expansion from the relevant governmental authorities, and the figures presented do not consider disposal capacity beyond this licensed amount. In addition to these amounts, as of December 31, 2018, we had an additional capacity of 23.0 million cubic meters for which licenses had not been obtained (13.3 million corresponding to unlicensed capacity at our Paulínia landfill, 9.6 million corresponding to unlicensed capacity at our Curitiba landfill and 76,000 corresponding to unlicensed capacity at our Jardinópolis landfill).

Our landfills generate revenue from disposal and tipping fees based on the type and weight of waste being disposed, which are paid by private and public collection companies, municipalities and large C&I waste generators. Our standard disposal agreement is aone- to three-year renewable agreement with annual price adjustment based on inflation indexes and charged on a monthly basis. While, as a result of the competitive bidding process, our landfill contracts with our municipal customers typically stipulate a fixed amount per ton of waste disposed, the amount invoiced to municipal customers on a monthly basis varies based on actual volume of waste disposed. For certain municipalities for which we provide waste collection services, such as Curitiba and Aracaju, we also provide landfill services; however, such landfill services are governed by separate contracts apart from our waste collection services.

With the exception of the landfill in Maceió, which is a concession established in a leased area, all of our landfills are established in duly-licensed proprietary or leased areas. All of our landfills include soil protection systems, draining and collection systems for percolated liquids and greenhouse gases, rainwater drainage systems and geotechnical monitoring systems, with regular reports controlled by environmental authorities.

Principal Customers in Landfills Segment

Our principal customers in our Landfills business segment are similar to those in our Collection and Cleaning Services segment. Principally as a result of our relatively high rate of internalization, there is a significant degree of overlap between our customers in the Collection & Cleaning Services segment and Landfills segment (47.2%). Collections and disposal services are generally provided pursuant to separate agreements with different pricing models. For more information, see “—Collection & Cleaning Services” above. Our main customers in this segment are municipalities, including public collection companies (accounting for 69.7% of our net revenues from this segment in 2018) and private customers, including large C&I waste generators (accounting for 30.3% of our net revenues from this segment in 2018). Our principal customers in our Landfills business segment include the municipalities of Curitiba, Maceió and Aracaju. In addition, other significant customers in this segment include the municipalities of Campinas and Paulínia and private customers such as Arcelor Mittal and Renova.

Licensing Regulations for Landfills

We work carefully to select the location of our landfills, transfer stations and greenfield projects, which are subject to strict environmental licensing due to the nature of our activities.

Under Brazilian law (Federal Law No. 6,938/1981), the construction, installation, expansion and operation of effectively or potentially polluting activities, such as landfills, transfer stations and power plants, are subject to environmental licensing by the relevant governmental authorities. Specifically, an environmental license is needed for approval of the feasibility of landfills, transfer stations and greenfield projects, initial construction and start of our operations, as well as for any future expansions.

With respect to environmental licensing, as a general rule, IBAMA (Instituto Brasileiro do Meio Ambiente e dos Recursos Naturais Renováveis) is the competent authority for the environmental licensing of undertakings and activities of national interest or capable of causing significant environmental impact regionally or internationally, or for activities located in certain protected areas such as indigenous lands or territorial waters, among others. The local environmental entities are responsible for the licensing of enterprises with a local impact. The state environmental authorities have jurisdiction to conduct the licensing process for activities whose impacts are restricted to their territory and whose licensing jurisdiction is not assigned to federal or local agencies.

In the state of São Paulo, the environmental agency is CETESB (Companhia Ambiental do Estado de São Paulo) and in the state of Paraná, the environmental agency is IAP (Instituto Ambiental do Paraná). Also, in some of the larger municipalities in which we operate there are local regulators that enforce their own rules and licensing procedures. For example, in the city of São Paulo, we are subject to licensing by the Secretary for the Environment (Secretaria do Verde e Meio Ambiente).

The specific requirements to operate a landfill in Brazil vary from location to location, depending in part on the particular characteristics, size, location, and potential environmental impacts of each landfill. The environmental licensing process in Brazil, as a general rule, consists of a three-step system, in which each license is contingent upon the issuance of its preceding license, as follows:

•

Preliminary License (“LP”): granted during the preliminary stage of planning of the enterprise or activity approving its location, conception and environmental feasibility, and sets forth the basic requirements to be met during the subsequent stages of its implementation. Generally, LPs will only be issued upon the successful completion of an environmental impact study (such as the Environmental Impact Assessment and the Environmental Impact Report –Estudo de Impacto Ambiental e Relatório de Impacto Ambiental);

•

Installation License (“LI”): authorizes the implementation of the project and commencement of construction which culminates in a final review by the relevant environmental agency before the facilities begin operating. Applications for the LI must be made through the applicable environmental authority accompanied by an environmental report ensuring compliance with the requirements of the LP, and a certificate issued by the municipal government regarding land use; and

•

Operational License (“LO”): after implementing the project in accordance with all previously established requirements and undergoing a final review, the operation of the project is authorized in compliance with the technical conditions set forth therein, including any environmental control measures and operating conditions. Applications for the LO must be made through the applicable state-level environmental authority accompanied by an environmental report ensuring compliance with the requirements of both the LP and the LI.

Environmental licenses are issued on a conditional basis, meaning that they set forth technical requirements and obligations that must be complied with in order to maintain the validity of the respective licenses. The accomplishment of technical conditions may involve the adoption of specific pollution control measures and other actions that may result in high costs to us.

In addition to the general guidelines set by the Brazilian federal government, each state has the power to issue specific regulations governing environmental licensing procedures under its jurisdiction. In addition, depending on the level of environmental impact caused by the exploratory activity, the procedures for obtaining an environmental license may require assessment of the environmental impact and public hearings, which can considerably increase the complexity and duration of the licensing process and expose the relevant operations to potential legal claims.

Once granted, licenses must be renewed periodically to ensure continuous compliance with the previous technical requirements. The maximum term for environmental licenses is five years for LPs, six years for LIs and 10 years for LOs. Every environmental license must have its renewal request to be presented to the competent agency on a timely basis (generally, at least 120 days prior to expiration), and the validity of licenses will be extended automatically until the environmental body has rendered a decision on the renewal request.

Failing to secure licenses or authorizations from the environmental agencies for the construction, implementation, modification, expansion and/or operation of potentially pollutant activities and/or enterprises will subject the violator to criminal and administrative sanctions, including the imposition of penalties of fines, suspension of activities, deactivation and demolition, among others. These penalties are also applicable if a project developer fails to fulfill the conditions established in its environmental license.

In addition to the above technical requirements, the installation, expansion and operation of our landfill operations in areas considered close to communities and other population centers may require us to consult with representatives of potentially affected communities, social movements and local government organizations. We may be required to negotiate with such groups as a condition to obtaining local government approvals and the necessary environmental licenses for our landfills.

Greenfield Projects

The landfill business is characterized by high barriers to entry resulting from the significant capital costs of landfill development, increasingly stringent environmental legislation and the lengthy and uncertain permitting process for new landfills.

Through our many years of experience in the landfill business, we have become one of the leading experts in landfill siting, development and operation in the Brazilian waste management industry. We have assembled a team of specialized professionals that monitors various locations for potential landfill site acquisitions, taking into account environmental, demographic, economic as well as other aspects. We compile this information into a continuously updated database that we use in making landfill site acquisition decisions. Once a decision has been made to acquire a landfill site, our specialized team of regulatory and licensing experts play a critical role in obtaining the necessary licenses and approvals to develop and operate the contemplated landfill. We have developed specialized knowledge and experience in managing the regulatory process at the federal, state and municipal levels, and our technical teams are capable of carrying out complex analyses on proposed landfill sites, including sophisticated geotechnical and topographical surveys. These analyses are then used to prepare detailed reports that are submitted to the licensing authorities, which can help expedite the licensing process. We also possess an experienced landfill project development team, which conceives all landfill projects with the appropriate safety features while seeking to maximize the utility to be derived from the landfill site. In addition, we possess an active M&A team that is dedicated toward identifying and evaluating potential acquisition targets as well as new landfill project developments, with specialized knowledge in integrating these new projects into our operations. After a landfill has been developed or acquired, our landfill operations team comes into play with its several years’ experience in managing landfill operations.

To satisfy future disposal demand, we are currently developing three greenfield landfill projects in strategic locations that we believe are located in underserved regions of Brazil. These three greenfield projects have a combined potential processing capacity of over 2,700 tons of waste daily, adding significant value to our existing landfill infrastructure and will help to replenish our landfills’ capacity in the future. The greenfield project related to CGR Ceará (Caucaia) was discontinued as after a detailed analysis we determined that the project was not economically interesting. However, we are continuously seeking opportunities and analyzing potential new projects.

We cannot assure you that all proposed or future expansions of our greenfield projects will be successfully realized as intended or at all.

Oil & Gas (O&G)

Our Oil & Gas segment provideson-site andoff-site biological remediation of soil that has been contaminated with oil or other pollutants as well as cleaning of storage tanks. We provide remediation and cleaning services in several sites and transfer the contaminated soil to our biopile facilities located in the Paulínia and Curitiba landfills. In these facilities, the soil goes through a bioventing process whereby contaminated soil is stacked into engineered piles or cells with the aim of enhancing conditions required for biodegradation by controlling oxygen and nutrients such as phosphorus, nitrogen and water. Bacteria or microorganisms are added to the waste and the soil, in order to degrade hydrocarbon contaminants such as diesel that are affixed to the soil particles. Our Oil & Gas segment accounted for only 1.9% of our total net revenues from services rendered in 2017 and 1.2% in 2018.

This segment’s soil remediation is provided primarily to one main customer, Petrobras, which accounted for 71.4% of the Oil & Gas segment’s net revenues from services rendered in 2017 and 100% in 2018. Petrobras contracts with us to clean contaminated sites on an as needed,per-engagement basis, rather than on a fixed or term basis. Accordingly, revenues derived from our Oil & Gas segment are highly dependent on demand from Petrobras, and are therefore subject to volatility in direct correlation to increases or decreases in Petrobras’ need for soil remediation services.

Value Recovery

Through the Value Recovery segment, we develop processes to convert and recycle collected waste into usable and efficient forms of energy and/or recyclables which can be sold to third parties. We also have the capabilities to carry out traditional recycling activities, including the recycling of complex electronic devices. This segment is driven by public and private markets that view environmental stewardship as a top priority.

Our activities in our Value Recovery segment can be divided into foursub-segments: (i) landfillgas-to-energy,(ii) co-processing and blending, (iii) reverse manufacturing and waste recycling and (iv) carbon credit trading, each described in greater detail as follows.

We are currently in the process of selling our landfillgas-to-energy business. The sale has been approved by our board of directors and negotiations are ongoing. However, the sale transaction is subject to the approval of the holders of our debentures, which approval remains pending. As of December 31, 2018, the energy business was classified as a disposal group held for sale and as a discontinued operation. As such, the results of operations our energy business are no longer presented within our Value Recovery segment.

LandfillGas-to-Energy

Energy generated from landfill gas is considered a renewable resource, since this fuel source is derived from household waste and other materials that have been deposited in landfills, and, therefore, because it is considered sustainable, it is eligible to tax benefits.

Our landfill operations naturally produce methane as well as other biogases from the decomposition of organic compounds. These biogases are readily available, renewable energy sources that can be gathered and used beneficially as an alternative to fossil fuels or to generate electricity. We capture these biogases at our landfills using drains installed throughout our landfills, channeling them to processing plants through a gas network interconnecting the drains. At our power plants, these biogases go through a process of filtration and cooling to fuel the turbines that burn biogas and generate electricity.

We have been generating electricity from our landfill gases since 2014. We currently operate three landfillgas-to-energy generation facilities at our Curitiba, Tremembé and Guatapará landfills, with a total installed capacity of approximately 18.5 MW and energy generation and sale of 111.4 MWh in 2018 and 82.0 MWh and 49,1 MWh in the years 2017 and 2016, respectively. In addition, we have received approval for the required permits to develop newgas-to-energy generation facilities at our Paulínia, Maceió, Piratininga, Aracaju and Jardinópolis landfills, which together comprise a total potential capacity of additional 40.6 MW.

We sell approximately 80% of the energy we generate from our biogas generation operations to private customers in the free market pursuant to power purchase agreements usually on three-year terms with annual inflation-based price adjustments, and the remaining approximately 20% in the spot market to benefit from the more volatile Brazilian energy market. In 2018, we generated and sold 111,414 MWh of energy generated from our landfillgas-to-energy operations (82,005 MWh and 49,081 MWh for the years 2017 and 2016, respectively).

Co-Processing

Co-processing is the use of waste materials as substitutes for primary fuel and raw materials in industrial processes, such as cement production. A wide range of waste materials may be used inco-processing, ranging from papers, plastics and wood to industrial byproducts, such as used oil, tires, solvents or paint sludge, or even obsolete pesticides and other organic waste materials.Co-processing offers a significant potential for the reduction of greenhouse gas emissions from fossil fuels, primarily by increasing the energy recovery factor from industrial waste streams that would have otherwise been destined to landfills and incinerators.

We maintain commercial agreements with some of the largest industrial companies in Brazil for collection and treatment of certain types of industrial waste forco-processing into a form of fuel commonly referred to as a RDF (refuse-derived fuel). RDF is a combustible “blend” with high energy output value that can be used in a variety of contexts, including, most commonly, in cement kilns, boilers and biomass plants.

We operate twoco-processing facilities, one in Sorocaba, São Paulo and another in Balsa Nova, Paraná.Co-processing employees use equipment such as backhoe loaders, wheel loaders or lifts to move and mix the waste, and use grinders and screeners to create a homogeneous blend. Then, employees use machines to handle the material and to pack the blend into large containers, bulks or barrels, which are then transported to the cement plants by contracted third parties.Co-processing is not a capital-intensive process. As of December 31, 2018, ourco-processing and blending facilities have a daily processing capacity of 700 to 900 tons of waste.

We supply RDF free of charge primarily to cement plants for use as an energy input in their industrial ovens. While we do not currently generate additional revenues from the supply of RDF to cement plants, we do receive collection and disposal fees from the industrial companies producing the waste that is used as an input in theco-processing to produce RDF. We may, however, opportunistically pursue opportunities to monetize ourco-processing activities in the future through the sale of RDF should market conditions so permit.

Waste Recycling

We operate one waste recycling facility at our Paulínia landfill with capacity to process approximately 40 thousand tons of waste per year, the primary function of which is to segregate inorganic from organic waste and have contracted the construction of a materials recovery facility (“MRF”) in the Paulínia landfill with capacity to handle 500 tons of MSW per day.This new MRF facility started its operations in October 2018. Organic waste with high energy output value is converted into RDF by means of theco-processing described above and supplied to cement plants, while metals and plastic waste products are sold as commodities, with the remaining waste being disposed at our Paulínia landfill.

We also operate one reverse manufacturing facility that breaks down complex electronic devices and products with diverse components into simple and easily disposable materials. Our reverse manufacturing services are offered pursuant to medium-term contracts with large electronic-producing companies that seek our specialized services to limit the environmental impact of the disposal of their electronic waste output. The component parts of the electronics that we collect, primarily metals, electronic parts and plastic waste products, are sold as commodities. We recycle such electronic devices in an efficient manner, ensuring that at least 85% of the original parts are effectively recycled and reused. In 2018, our subsidiary Oxil recycled 101 thousand tons of toners and 249 thousand tons of other electronics.

We also operate a mechanized recycling system that has the capacity to process various types of construction materials. The materials are converted into raw materials with physical properties similar to unused products, however, with more competitive costs. Recycled materials produced as part of this process include sand, gravel, stones, mortar, concrete, crushed ceramic material and other materials that can be used in various aspects of the construction industry.

Contracts in connection with our recycling operations generally provide for the payment of a collection fee and set forth the terms pursuant to which the recycling byproduct may be sold.

In 2017, Brazilians generated about 78.4 million tons of municipal solid waste and recycled and composted about 1.5 million tons of this material, equivalent to a 1.9% recycling rate, according to ABRELPE data. As Brazil continues to develop its regulatory framework with an increasing focus on environmental sustainability, we believe that there may be attractive opportunities to capitalize on recycling-related activities. In addition, we believe that higher recycling rates would bode well for the longevity of alandfill-focused disposal model in Brazil by making use of waste that would otherwise have been disposed in landfills. We also perceive the expected environmental benefits of increased recycling as an important social benefit that is consistent with our philosophy of environmental sustainability, by, for example, decreasing the use of primary resources and energy, and reducing water and air pollution (including greenhouse gas emissions).

Carbon Credit

Under the Kyoto Protocol, signatories are required to abide by certain caps, or quotas, on the amounts of greenhouse gases emitted, and, to meet such quotas, participants are allowed to trade carbon credits to offset their carbon emissions. Carbon credit revenue consists of a tradable certificate or permit representing the right to emit carbon dioxide, which we sell to carbon emitters. Our landfill operations produce methane as well as other biogases as a result of the biological decomposition of organic waste in our landfills, some of which we process by burning such gases in our Paulínia landfill to convert them into carbon dioxide and carbon monoxide. As methane is a greenhouse gas that has approximately 21 times the heat-trapping capacity of carbon dioxide, our process of reducing methane into carbon dioxide and carbon monoxide generates carbon credits.

We have been selling carbon credits generated from our landfill operations since 2006, at prices of approximately EUR1.98 per Certified Emission Reduction (one Certified Emission Reduction is equivalent to one ton of carbon dioxide avoided in the atmosphere). We sell the carbon credits we generate to the NEFCO (Nordic Environment Finance Corporation) pursuant to a procurement contract that expires in 2020, which it uses in order to meet Norway’s requirements under the second commitment period of the Kyoto Protocol.

Our stock of carbon credits is measured by United Nations and recognized companies, through approved methodologies, to quantify the amount of carbon credits that we can sell. From 2015 to 2018, we had sold a total of 1,870,440 Certified Emission Reductions carbon credits resulting in total revenues of R$13.8 million.

We anticipate that a continued focus by regulatory authorities on environmental issues could increase the demand for carbon credits we generate, and could present an attractive opportunity to generate ancillary revenues in the future.

Principal Customers Value Recovery

Our principal customers in our Value Recovery business segment are Apple, Votorantim Cimentos, HP, Goodyear, ABB, Dow Chemicals, CPFL and Camil.

Competition

The Brazilian waste management industry is highly fragmented and, accordingly, we face competition in all aspects of our operations. According to internal studies based on ABRELPE data and other public information related to landfills locations and size, in 2017, no one player in the Brazilian waste management sector had greater than a 15% market share, and the top five players collectively had an approximately 42.4% market share in terms of volume. Based on our internal studies based on 2017 data, we were a significant participant in the waste management company, in 2017 in terms of waste disposal market share, with 14.7% market share.

The graph below demonstrates our market share in the Brazilian landfills market relative to our main competitors in 2017 according to internal studies based on 2017 ABRELPE data, which is the most recent data available:

LOGO

Competition in the waste management industry is mainly driven by a few large companies and several smaller and regionally-based companies. We believe that most of our competitors are typicallyfamily-owned companies that lack the scale, technology and skilled management that we possess. Nevertheless, in any given market, certain competitors may have larger operations and greater resources available than us. Municipal landfills, in most part, are used exclusively to dispose the waste generated by its own municipality, therefore the competition that we face with our landfills is not significant.

Our principal competitors in each of our business segments include:

•

Collection and Cleaning Services: Solvi, Vital, Marquise, Ambipar, Sustentare, Constroeste, Seleta

•

Landfills: Solvi, Vital, Haztec and Proactiva (Veolia), JSL, Marquise

•

Oil & Gas (O&G): Essencis, Ambiental do Brasil, Geoclock, Arcadis

•

Value Recovery: Essencis, Haztec, Serquip, Renova, Ecoprimos, Revalore

We compete for municipal contracts and private sector accounts primarily on the basis of price and the quality of our services. Operating costs, disposal costs and collection fees vary throughout the areas in which we operate. The prices that we charge are determined locally, and typically vary by volume and weight, type of waste collected, treatment requirements (especially the availability to treat the leachate generated in the landfill), risk of handling or disposal, frequency of collections, distance to final disposal sites, the availability of airspace within the geographic region, labor costs and amount and type of equipment furnished to the customer. From time to time, our competitors reduce the price of their services in an effort to expand market share or to win a competitive bid municipal contract. Our ability to maintain and increase prices in certain markets may be impacted by our competitors’ pricing policies. This may have an impact on our future revenue and profitability.

Marketing and Sales

Our marketing and sales efforts are conducted on a company-wide basis, rather than individually for each of our business segments. For our municipal customers, we enter into competitive bidding processes to win long-term contracts to provide municipal collection services. Due to the strength of our localized operations and highly experienced regional management teams operating through our four main regional hubs, we maintain close relationships with keydecision-makers throughout our markets, which we believe positions us well to capitalize on new municipal contracts and renew existing ones. For our private sector customers, our marketing and procurement efforts are mainly focused on the segmentation of the target market (principally the manufacturing industry) and the customization of marketing proposals.

Seasonality

We experience moderate revenue seasonality in our business segments due to the location of certain landfills in regions that depend heavily on tourism, therefore leading to an increase in the volume of waste processed at these landfills in the summer months. Moreover, periods of heavy rain will generate a higher volume of leachate at our landfills leading to an increase in costs.

On a cash basis, we experience a higher rate of payments on our accounts receivable from municipalities during the first three months of each year, as Brazilian municipalities receive an annual transfer of federal funds at the beginning of the year. The rate of payments on accounts receivable progressively decreases as the year progresses, with the fourth quarter of each year exhibiting the longest collection periods.

In addition, we also experience a lower overall rate of payments on our accounts receivable from municipalities during election years and during the first quarter of the years following elections. Municipal elections were last held in Brazil in 2016 and the next municipal elections in the regions in which we operate are expected to be held in 2020.

Raw Materials and Suppliers

Our principal raw materials are in relation to the purchase and leasing of the light vehicles, trucks and heavy machinery that comprise our fleet together with the diesel fuel needed to operate our collection and transfer vehicles. In Brazil, the collection and transfer trucks that comprise our fleet are manufactured and sold primarily by Volkswagen, MAN, Mercedes Benz and Ford. As of December 31, 2018, we owned approximately 56% of our fleet, while 44% was leased or rented. Our leasing contracts for our fleet are typically for a term of four years, with the option to buy the leased equipment at the end of the leasing period at a set price. As of December 31, 2018, the aggregate amount of the minimum lease payments under our leasing contracts was R$36.5 million. In addition, on January 1, 2019 we adopted IFRS 16 – Leases, for which we recognized aright-of-use asset and a lease liability at the present value of R$23.3 million. For further details, see “Item 5. Operating And Financial Review And Prospects—New Accounting Standards Not Yet Adopted”.

We purchase fuel from a number of distributors in Brazil, principally from Ipiranga Produtos de Petróleo S.A., pursuant to long-term contracts providing us with generally more attractive pricing than we could otherwise obtain in the open market. Our diesel fuel contract with Ipiranga provides for the purchase and delivery of a minimum of 33.6 million liters of diesel fuel per year at a fixed price, with prices being adjusted on a yearly basis. Fuel delivery takes place upon request. Prices are set by Ipiranga and are charged uniformly to all companies in a similar industry at a set rate. The contract does not have a fixed term but may be cancelled by either party with at least 30 days’ advanced notice.

We also contract with third parties that provide leachate treatment and disposal, which consist of costs associated with the physical, chemical and biological treatment of leachate as well as costs associated with the transportation of this residue from our landfills to treatment plants, which in the majority of cases are offsite and operated by third-parties. We and our subsidiaries have entered into ten service contracts with various suppliers for the collection, treatment and transportation of leachate. The price of the service contract is calculated based on the price per cubic meter of leachate, and the aggregate value of our service contracts for leachate collection, treatment and transportation is R$50.7 million as of December 31, 2018. All agreements are set to expire on September 1, 2019, and we currently expect that the ongoing renewal process will be completed before that time. The duration of our service contracts typically vary in duration from six months to eight years, depending on the amount of services provided.

Insurance

We have insurance policies covering (i) environmental damage; (ii) civil responsibility; (iii) our fleet, equipment and properties; and (iv) directors’ and officers’ insurance, among others. We believe that the insured amounts are sufficient, considering our business activities and exposure to risk.

Regulation

There have been significant developments in the regulatory environment of the waste management industry in Brazil at the federal, state and municipal levels. These new regulations have significantly benefited the waste management operators, and have created opportunities for the remediation business as well as for services in the collection, treatment and destination of all waste types. Recently, Brazilian environmental regulatory agencies have been increasing their enforcement activities aimed at reducing environmental damages and enforcing current regulations.

The Brazilian waste management industry is heavily regulated at the federal, state and municipal levels. At the federal level, the main regulatory bodies are: IBAMA (Instituto Brasileiro de Meio Ambiente) and National Council of the Environment (CONAMA), which are part of the Ministry for the Environment, and ANVISA (Agência Nacional de Vigilância Sanitária). The federal authorities work with the state authorities. For example, in the State of São Paulo, the environmental authorities are CETESB (Companhia Ambiental do Estado de São Paulo) and SMA (Secretaria de Meio Ambiente), while in the State of Paraná, the environmental authorities are IAP (Instituto Ambiental do Paraná) and SEMA (Secretaria de Estado do Meio Ambiente e Recursos Hídricos). In addition, in some of the larger municipalities there are local regulators that enforce their own rules. For example, in the city of São Paulo, the environmental authority is the Secretary for the Environment (Secretaria do Verde e Meio Ambiente) and, regarding health issues, COVISA (Coordenação de Vigilância e Saúde).

The Brazilian Constitution grants federal, state and municipal governments the authority to issue environmental protection laws and to pass regulations based on those laws. While the Brazilian federal government has jurisdiction to issue environmental regulations setting minimum general standards for environmental protection, state governments have the jurisdiction to issue stricter environmental regulations. Municipal governments may only issue regulations regarding matters of local interest or aiming at supplementing federal or state laws.

Environmental Regulations

Environmental Liability

Environmental liability may be attributed under civil, administrative and criminal spheres, with the imposition of administrative and criminal sanctions, in addition to the obligation to redress the damages caused.

The Brazilian National Environmental Policy sets forth strict civil liability for environmental damages. The fact that the offender’s operations are licensed does not waive such liability. Under Brazilian law, legal entities and individuals directly or indirectly involved in the damaging or polluting activities are subject to joint and several liabilities.

Criminal liability also applies to both individuals and legal entities that violate environmental laws. As a result, a legal entity’s officer, administrator, director, manager, agent or proxy may also be subject to criminal liability if he is negligent or commits environmental crimes. Settlement of civil and administrative proceedings does not prevent criminal prosecution.Freedom-restricting-penalties (confinement or imprisonment) are often reduced to right-restricting penalties, such as community services.

Administrative penalties include single fines of up to up to R$50 million, or daily fines, full or partial suspension of activities, right-restricting penalties and orders to redress damages, among others. In addition to criminal and administrative sanctions, Brazilian environmental laws require the offender to repair or indemnify for damages caused to the environment and to third parties. Enforcement of fines may be suspended upon settlement with environmental authorities for damage redress. In the event of failure to redress damages or to pay fines, the corporate veil piercing doctrine may apply.

In addition, according to Brazilian legislation, after the closure of a landfill, we must continue to monitor the underground and surface water and maintain the leachate treatment, the gas collection system, the drainages and the capping of closed landfills for a long period, until the closed site is no longer potentially harming to the environment or the community.

Management of Waste

The Solid Residues National Policy, which is outlined by the Federal Law No. 12,305/2010, determines that the management and final disposal of residues must not cause any damage to the environment, nor any inconvenience to the public health and welfare. As a result, Brazilian legislation regulates the sorting, collection, storage, transportation, treatment and final disposal of residues, and states that parties outsourcing such activities are jointly liable with the contracted third parties in the event of environmental damages.

Inappropriate disposal as well as potential accidents resulting from the transportation of waste can be a factor of environmental contamination and trigger the imposition of penalties at the administrative (which could include warnings, fines, embargoes, and suspension of financing and tax benefits) and criminal levels, despite the obligation to redress the damages caused.

The Solid Residues National Policy also created a new legal regime intended to produce a positive impact on the waste management industry. The creation of this new regime established relevant waste management sustainability goals through the following measures:

•

shared responsibility among manufacturers, importers, distributors, retailers, consumers and governmental agents for the life cycle of certain products, which places specific obligations on each of these entities across the waste management chain;

•

regulation of the regional and local waste management authorities, in order to guide such authorities on the management of waste and allocate resources to those entities for promoting cost reduction programs;

•

requires the private sector to develop waste management plans, which includes segments such as mining, industrials, hospitals, drugs manufacturers, water and sewage companies, construction companies, ports, airports, roads, railways and companies within the agribusiness, among others. Those that do not comply with the Solid Residues National Policy would not be entitled to eventual environmental licenses that would be required to their businesses;

•

prohibits the disposal of solid waste into dumps, which shall be gradually eliminated or cleaned up (decontaminated);

•

establishes the mandatory reverse logistics, which consists in returning products post consumption from the final consumer to the manufacturer or importer independently from the public waste collection; and

•

tax incentives for energy generated from waste.

Finally, as thewaste-to-energy technology becomes more efficient and cost effective, new opportunities are being presented to Brazilian waste management companies to enter into the power generation business, notably through landfill gas and the development of new businesses to supply the international demand of carbon credits. Aswaste-to-energy technology—such as in our value recovery segment—becomes more efficient and cost effective, new opportunities might arise for waste management players in Brazil to enter into the power generation business through landfill gas and clean waste incineration, among other methods.

The National Solid Waste Policy also sets forth specific obligations with a view to reduce the volume of solid residues and mitigate the adverse impact on human health and on the environment, such as the take-back obligations imposed to manufacturers or other actors in the product life cycle of certain products.

Pursuant to the National Solid Waste Policy Act, outlined by the Federal Law No. 12,305/2010, administrative penalties applicable to the inadequate provision of solid waste, liquids and gases, whether or not causing effective pollution, include, among others, the embargo of the activity and fines up to R$50 million. According to our experience, the maximum penalty is only imposed in cases of severe damage to the environment.

Contaminated Areas

The existence of contamination may be confirmed by investigatory evaluations carried out by specialized technical consultants, through the assessment of past and current conditions of the area, occupancy history, natural characteristics, sampling of soil and groundwater, among other aspects. An area may be deemed as contaminated when the concentration of polluting substances is higher than the quality standards set forth by the applicable legislation. Contamination events may arise from planned, accidental or even natural pollution due to the disposal, accumulation, storage or infiltration of substances or wastes, resulting in adverse impacts to the soil and water.

In the civil sphere (strict liability, irrespective of fault), the remediation of environmental damages involves joint and several liability, which means that the detection of contamination requires that actions be taken by the causer of the damage (even if it does not have the possession or ownership of the area), by the owners and occupants of the property, as well as by whomever benefits itself from the existing environmental damage. The environmental agency may require from any of the aforementioned agents that corrective steps be taken to establish quality levels compatible with the present and future use of the area.

It is also important to bear in mind that claims seeking the restitution of environmental damages are not subject to cap values. Likewise, liabilities for environmental damages are not subject to statute of limitations and, therefore, shall not be extinguished by the course of time.

D.	Property, Plant and Equipment

Our principal property and equipment consists of land, landfills, buildings, vehicles and equipment. We own or operate 12 landfills, five transfer stations, three facilities for the treatment of medical waste, two units for blending hazardous waste, one recycling and RDF unit, one reverse manufacturing facility, two biogas power generation plants and three effluent treatment facilities. In addition, we own the land on which we intend to develop three additional landfills. As of December 31, 2018, we also owned or leased a fleet of 1,539 vehicles consisting mostly of collection and transfer trucks.

We also are responsible for a closed cell on the Paulínia landfill, which landfill is composed of a total of two cells. The total amount provisioned as a contingency for landfill closure and post-closure obligations was R$92.8 million as of December 31, 2018. The post-closure period generally runs for 20 years after final landfill’s site closure.

OPERATING AND FINANCIAL REVIEW AND PROSPECTS

A.	OperatingResults

Introduction

The following management’s discussion and analysis of financial condition and results of operations should be read in conjunction with our audited financial statements included elsewhere in this annual report on Form20-F. This annual report contains forward-looking statements that involve risks and uncertainties. Our actual results may differ materially from those discussed in the forward-looking statements as a result of various factors including, without limitation, those set forth in “Item 3.D. Key Information—Risk Factors” and the matters set forth in this annual report generally.

Liquidity Constraints and Breach of Financial Covenants

As a result of liquidity constraints, we were unable to comply with the financial and other covenants included in our Debt Instruments and, as a result, are currently in default under our Debt Instruments. Since we were unable to obtain a waiver from the banks that hold the Debt Instruments by December 31, 2018 in relation to such defaults, pursuant to IFRS accounting rules, we were required to reclassify the total outstanding amount under the Debt Instruments (consisting of R$1,548.3 million) as short-term obligations in our financial statements as of and for the year ended December 31, 2018 included in this annual report.

The terms of the Debt Instruments required, among other things, that as of December 31, 2018, our consolidated net debt to EBITDA ratio must be 4.0x or less. In addition, the Debt Instruments also contain a covenant that required our debt service coverage ratio to be at least 1.2x. As of December 31. 2018, our consolidated net debt to EBITDA was 7.9x, and our debt service coverage ratio was negative 15.6x. In addition, the terms of the Debt Instruments required that by December 31, 2018 we register certain liens on certain real estate relating to operational landfills with the appropriate governmental agencies and to provide certain documents listed in the annexes to the Debentures, which we were also unable to comply with by December 31, 2018.

Therefore, as a result of the breach of the consolidated net debt to EBITDA ratio and the debt service coverage ratio, the failure to register the relevant liens and to provide certain of the documents required to be provided, we are in default of our obligations under our Debt Instruments. These defaults entitle the banks that hold the Debt Instruments to accelerate the debt obligations and declare that all amounts owing under the Debt Instruments are immediately due and payable.

The Debt Instruments are secured by collateral consisting of a lien on all real estate relating to our operational landfills, a lien on all material subsidiaries controlled, directly or indirectly, by us and a fiduciary assignment of the remaining balance originated from the foreclosure of liens granted in relation to the Debt Instruments. In addition, the Debt Instruments are secured by a fiduciary assignment of certain real estate owned by us and a fiduciary assignment lien on all of the common shares of the Company (except for 4.38% secured for the benefit of Angra). In addition, the Debt Instruments are also guaranteed by all material subsidiaries controlled, directly or indirectly, by us. The breach of the obligations under the Debt Instruments entitles the holders of the Debt Instruments to enforce against any collateral securing the Debt Instruments.

In addition, on March 6, 2018, Angra confirmed the exercise of its put option to sell all of its shares of the Company. While we were required to pay the exercise price of approximately R$40.3 million by September 6, 2018, as of the date of this annual report, we have not yet made any payments to Angra due to our liquidity constraints, which constitutes a default under the share put option agreement entered into with Angra. As a result, Angra may seek certain remedies afforded to them under the share put option agreement and otherwise under Brazilian law, including the enforcement of their security interest of 4.38% of the share capital of the Company.

Furthermore, as of December 31, 2018, the Company had aggregate overdue trade accounts of R$85.9 million, and there can be no assurance that such trade creditors will not demand immediate payment or use a variety of legal remedies to enforce their claims, which may further constrain our liquidity, further jeopardize our ability to continue as a going concern and increase the risk that we become subject to bankruptcy proceedings. For further information, please see note 15 of our consolidated audited financial statements included elsewhere in this annual report.

We have identified several significant other obligations arising during 2019 that require funding through liquidity, primarily relating to (1) the payments we are required to make for severance and other demobilization costs related to discontinued operations (for example, the contract with the municipality of São Paulo for cleaning services, which will terminate on June 1, 2019) and (2) capital expenditures (e.g., new trucks and equipment) required in connection with contract renewals, such as the investment obligations arising under the contract with the municipality of Curitiba for cleaning services, which was renewed on January 3, 2019 for an additional five year period.

Our management has concluded that substantial doubt exists with respect to our ability to continue as a going concern through one year after the date of issuance of our audited financial statements as of and for the year ended December 31, 2018. In addition, as a result of our material liquidity issues, our independent auditors have indicated, in their report on our audited financial statements that there exists significant uncertainty that could raise doubt about our ability to continue as a going concern. These doubts regarding our ability to continue as a going concern relate to our history of suffering recurring losses from operations, the ongoing process of renegotiating our debt obligations and our net capital deficiency, resulting in substantial doubt as to our ability to continue as a going concern. The audited financial statements do not include any adjustments that might be necessary if we are unable to continue as a going concern.

For further information, see “Item 3.D. Key Information—Risk Factors—Risks Related to Our Business—As of December 31, 2018 we recorded significant negative working capital and capital deficiency, we are currently in breach of certain financial covenants and contractual obligations, and our ability to avoid a judicial reorganization is dependent on our ability to successfully complete a debt restructuring and significantly improve our liquidity position” and “—Our auditors have issued a “going concern” audit opinion, and our ability to continue as a going concern is dependent on our ability to significantly improve our liquidity position.”

The December 2017 Transaction

Prior to the Transaction, the Registrant had limited or no assets, operations or activities. The Registrant was incorporated to become the holding entity of the Company to effect the Transaction. Considering that substantially all of the shareholders of the Company exchanged their shares of the Company for shares of the Registrant, the Transaction was accounted for as a reverse recapitalization transaction. The historical operations of the Registrant are deemed to be those of the Company. Thus, the financial statements included in this annual report reflect (i) the historical operating results of the Company prior to the Transaction, as restated as of and for the years ended December 31, 2016, as described under “—Internal Evaluation Process and Previous Restatement of Financial Statements”; (ii) the consolidated results of the Registrant and the Company following the Transaction; (iii) the assets and liabilities of the Company at their historical cost; and (iv) the Registrant’s equity and earnings per share for all periods presented, each of which were previously reflected in our annual report on Form20-F for the year ended December 31, 2017 which was filed with the SEC.

As of December 31, 2017, Estre USA had assets of R$1.2 million reflecting its cash position and did not generate revenues from operations.

The main financial statement effects of the Transaction were as follows:

•

the receipt by the Registrant of R$37.1 million (US$11.2 million) from existing shareholders of Estre USA that did not redeem their public shares in connection with the Merger;

•

the receipt by the Registrant of R$425.6 million (US$128.7 million) from the gross proceeds of the sale of 15,438,000 of our ordinary shares and 3,748,600 warrants to purchase ordinary shares to certain institutional investors unaffiliated with us pursuant to the PIPE Investment;

•

the payment of R$366.0 million (US$110.6 million) used to partially repay certain of our indebtedness pursuant to the Debt Restructuring, which was repaid using the net proceeds from the transactions referred to above;

•

a discount of an amount corresponding to 25% of the prepaid amount of our debentures and related debt acknowledgment instrument as of such date, totaling R$91.5 million (US$27.7 million), and reclassification of the remaining balance of debentures and related debt asnon-current; and

•

payment of R$96.7 million (US$29.2 million) in fees and expenses in connection with the Transaction.

Internal Evaluation Process and Previous Restatement of Financial Statements

In response to the findings of the Internal Evaluation Process, the Company’s audited financial statements included in this annual report as of December 31, 2016 and January 1, 2016 and for the year ended December 31, 2016 (as well as the audited financial statements for the year ended December 31, 2015 which are not included in this annual report) were restated to reflect certain adjustments, as described below. Such restatement was previously reflected in our annual report on Form20-F for the year ended December 31, 2017 which was filed with the SEC.

Overview

On March 1, 2018, the Brazilian Federal Police executed search warrants at a number of companies in the cities of São Paulo, Santos, Paulínia, Belo Horizonte and Lamim, including the premises of Soma, as well as our corporate offices. This action formed part of theso-calledOperation Descarteeffort of the Brazilian Federal Police working in conjunction with the Brazilian tax authorities within the ambit of the broaderLava Jato task force. The stated objective ofOperation Descarteis dismantling a criminal money laundering scheme focused on payments made by companies operating in the Brazilian waste management industry.

In the aftermath of the events of March 1, 2018, we instituted a special committee of our board of directors comprised of independent members of our board of directors for the specific purpose of evaluating our supply relationships and related matters at the Company, including Soma and our joint ventures, which we refer to herein as the “Internal Evaluation Process.” This Internal Evaluation Process was conducted by external legal counsel working together with external forensic service providers with a focus on the integrity of our supply relationships. For additional information, see “Item 8.A. Financial Information—Consolidated Statements and Other Financial Information—Legal and Administrative Proceedings and Investigations.”

In response to the findings of the Internal Evaluation Process, the Company’s audited financial statements as of December 31, 2016 were restated and such restatements were reflected in our annual report on Form20-F for the year ended December 31, 2017 which was filed with the SEC.

Tax Adjustments

Following our Internal Evaluation Process, we recalculated our taxes to reflect probable amounts due, including fines and interest, applying an income tax rate of 34% (principal), plus application of a 150% fine and an average 14.9% interest payment (fines and penalties). On this basis, we recorded provisions for Corporate Income Tax (Imposto de Renda de Pessoa Jurídica– “IRPJ”) and Social Contribution of Net Profits (Contribuição Social sobre o Lucro Líquido – “CSLL”) in an aggregate amount of R$25.6 million and R$26.0 million in the years ended December 31, 2017 and 2016, respectively, corresponding to impermissible deductions in the past in relation to the alleged unsupported payments made to specific suppliers and alleged impermissible amortization (as applicable) recorded from these transactions that may be challenged by the BFRS. In the case of taxes payable arising from unsupported payments made through Soma, our recalculated income taxes reflect only our proportional interest in this entity.

In connection with the adjustments described above, based on the advice of our external legal counsel, who assessed the risk of a potential loss as possible (and not probable), we did not establish provisions in the aggregate amount of R$212.4 million (as of December 31, 2017) corresponding to IRPJ, CSLL and IRRF taxes levied by the BFRS in relation to the tax assessments received by the Company and Cavo at the conclusion of 2017 alleging impermissible deductions with respect to certain allegedly unsupported payments made to specific suppliers and alleged impermissible deductions with respect to amortization derived from these transactions. For additional information, including information in connection with tax assessments received in the year ended December 31, 2018 (i.e. subsequent to the adjustments described in this section), see “Item 8.A. Financial Information—Consolidated Statements and Other Financial Information—Legal and Administrative Proceedings and Investigations.”

While no additional provisions were recorded in 2018, we partially reversed the loss recorded for the year ended December 31, 2017 in an amount of R$66.6 million, which corresponds to a reduction in the probable amounts due in respect of taxes as a result of a reduction in the amount of penalties applied in calculating the probable amount due, which we decreased from a penalty rate of 150% to a penalty rate of 20% after we self-reported certain outstanding tax payments as part of the tax regularization programs.

Key Factors Affecting Our Results of Operations

Brazilian Macroeconomic Environment

As a company with all of its operations and activities conducted in Brazil, our results of operations and financial condition are affected by Brazilian economic conditions. Most notably, we are impacted by Brazilian economic growth and its consequences on our customers’ ability to pay in a timely manner, particularly our municipal customers that may confront fiscal challenges and cash shortages in an adverse macroeconomic scenario. In addition, the Brazilian interest rate environment and inflation materially impact our financing costs, as 97.6% of our indebtedness was linked to floating rates as of December 31, 2018, with the majority linked to the Brazilian CDI rate as well as the Brazilian TJLP rate. Inflation in Brazil also impacts our revenue from services rendered, cost of services and other operating expenses as a result of our inflation-adjusted contracts with both our customers and suppliers as well as annual inflation adjustments that we are required to make pursuant to the collective bargaining agreements that we maintain with employees.

The Brazilian macroeconomic environment has historically been characterized by significant variations in economic growth, inflation and interest rates. Our results of operations and financial conditions are affected by these factors. The table below sets forth Brazilian GDP, inflation rates, interest rates, exchange rates and other key macroeconomic data as of and for the years ended December 31, 2018, 2017 and 2016:

Brazil experienced a 3.8% contraction in 2015 followed by an additional contraction of 3.6% in 2016. After contracting two consecutive years, GDP grew 1.0% in 2017 and 1.1% in 2018 according to IBGE.

Recently, the Brazilian political and economic scenario has been characterized by high levels of volatility and instability, including meager GDP, sharp fluctuations of the real against the U.S. dollar and increased levels of unemployment. Such scenario is in part due to economic and political uncertainties resulting from a global decrease in commodities prices as well as to corruption investigations of Brazilian state-owned and private sector companies, politicians and business executives. In particular, the ongoingLava Jato launched by the Office of the Brazilian Federal Prosecutor at the end of 2014 has probed members of the Brazilian federal government and other members of the legislative branch, as well as senior officers and directors of large state-owned as well as other companies in connection with allegations of political corruption including, more recently, individuals related to Company (for additional information, see “Item 3.D. Risk Factors—Risks Related to Compliance and Control” and “Item 8.A. Consolidated Statements and Other Financial Information—Legal and Administrative Proceedings and Investigations”). The resulting fallout from theLava Jato investigation contributed to, among other factors, the destabilization of the Brazilian economy and the ouster and the arrest of several prominent politicians, including the impeachment of former President Dilma Rousseff in August 2016, incarceration of former Brazilian President Luiz Inacio Lula da Silva in April 2018 and arrest of previous president, Michel Temer, in March 2019.

On October 28, 2018, Jair Bolsonaro, a retired military officer who represented the state of Rio de Janeiro in the lower house of the Brazilian Congress from 1991 through 2018, was elected the next President of Brazil and took office on January 1, 2019. During his presidential campaign, Bolsonaro was reported to favor the privatization of state-owned companies, economic liberalization, and social security and tax reforms. However, there is no guarantee that Bolsonaro will be successful in executing his campaign promises or passing certain favored economic and other reforms fully or at all, particularly when confronting a fractured congress. Adverse macroeconomic conditions in Brazil may persist to the extent Bolsonaro is unsuccessful in implementing these reforms and other adjustments.

For more information, see “Item 3.D. Key Information—Risk Factors—Risks Related to Brazil—Brazil continues to experience political instability, which may adversely affect us”.

Effects of Inflation and Interest Rates

Inflation rates in Brazil have been volatile in the past. According to the IPCA, Brazilian inflation rates were 3.75%, 2.95% and 6.29% in 2018, 2017 and 2016, respectively.

Inflation affects our performance primarily by affecting our revenues from services rendered, which is supported, in almost all cases, by contracts with annual inflation-adjustment clauses. Inflation also affects our results by increasing costs from inflation-indexed supply contracts, increasing expenditures primarily for diesel fuel, electricity, and leachate treatment and disposal as well as wage expenses through our collective bargaining agreements. In addition, some of our indebtedness is generally adjusted with reference to inflation indexes; for example, a significant portion of our debt bears interest based at the Brazilian CDI rate, which is partially adjusted for inflation.

The Brazilian government’s measures to control inflation frequently have included maintaining a tight monetary policy with high interest rates, thus limiting the availability of credit and reducing economic growth. Consequently, the official interest rates in Brazil at the end of 2017 and 2016 were 7.0% and 13.75%, respectively, as established by the Brazilian Central Bank’s Monetary Policy Committee (Comitê de Política Monetária) (“Copom”). In March 2018, Copom established a 6.5% interest rate, reflecting a historical low, which has been maintained until the day of this annual report. Despite the recent downward trend in interest rates, any potential future increase could negatively affect our profits and operating results, by increasing the cost associated with financing our activities.

Variations in Brazilian interest rates affect our financial liquidity and capital resources primarily by exposing us to the variations in our floating-rate lending. Substantially all of our debt accrues interest at floating rates, with 97.6% of our loans and financings indexed to Brazilian variable interest rates as of December 31, 2018, with particular exposure to the CDI rate (to which all of our debentures and related debt acknowledgment instrument are indexed), and, to a lesser extent, the Brazilian TJLP interest rate. Accordingly, rising interest rates significantly impact the costs of our indebtedness, increasing our finance expenses. Such an increase could in turn adversely affect our ability to pay our obligations to the extent it reduces cash on hand. Mismatches between rates contracted in assets versus liabilities and/or high volatility in interest rates may result in financial losses for us. The high interest rate environment in Brazil in recent years, impacted in part by high inflation environment, led to the suspension of interest payments and amortization of principal on our debentures since 2014 (for additional information, see “Item 3.D. Key Information—Risk Factors—Risks Related to Brazil”. An increase in inflation, as well as government efforts to combat inflation, may hinder the growth of the Brazilian economy and could adversely affect us”).

Write-off of Property, Plant and Equipment

We are the subject of certain allegations and investigations of misconduct. For further information regarding the related facts, see “Item 8.A. Financial Information—Consolidated Statements and Other Financial Information—Legal and Administrative Proceedings and Investigations.” As part of our historical response to the allegations and investigations of misconduct, we engaged independent consultants in November 2016 to review documentation regarding our transactions with certain identified suppliers during the 2010 to 2017 period. These consultants concluded in March 2017 that certain disbursements made by us were not properly supported by documentary evidence. On the basis of this historical investigation, our management made an accounting adjustment reflected in our financial statements as of and for the year ended December 31, 2017 resulting in thewrite-off of property, plant and equipment items totaling R$44.0 million relating to payments by us for goods and services that could not be properly documented during the 2010 to 2014 period. We also made an additionalwrite-off of property, plant and equipment of R$9.4 million reflected in our financial statements as of and for the year ended December 31, 2017 as a result of the related review of our inventory based on our improved controls and management systems. This earlier investigation did not capture payments made by Soma, which was the focus of our more recent Internal Evaluation Process. For additional information, see “Item 3.D. Key Information—Risk Factors— Risks Related to Compliance and Control.”

Participation in Tax Regularization Programs

In 2017, we entered into the Brazilian Tax Regularization Programs which allowed us to settle certain of our tax debts under administrative or judicial discussion. For additional information, see “Item 8.A. Financial Information—Consolidated Statements and Other Financial Information—Legal and Administrative Proceedings and Investigations—Tax Proceedings.” While these programs did not provide for amnesty of penalties or interest, it did allow us to resolve certain of our federal tax debts, including some of which were the subject of ongoing disputes, in installment payments. The programs also allowed the partial settlement of tax debts with the use of tax credits and/or the use of tax loss carryforwards. In order to benefit from this program, we were required to waive in advance any defense or rights in relation to administrative disputes involving the tax indebtedness.

The main impacts on the statement of profit or loss in relation to entering into this program in 2017 were (i) recognition of a gain of R$373.2 million recorded under “Income and Social Contribution Taxes” reflecting the recognition of tax loss carryforwards (previously not recognized as a deferred tax assets) that were applied in partial settlement of the tax debts under the Tax Regularization Program, (ii) a R$120.4 million increase in interest expenses recorded under “Finance Costs” reflecting interest accrued on the balance of taxes settled through the Brazilian Tax Regularization Program and (iii) a R$53.6 million loss recorded under “General and administrative expenses” reflecting a provision established corresponding to disputed amounts for which our management had not previously recorded provisions based on their determination that the risk of loss for such liabilities was not probable, and (iv) R$3.0 million in September 2017 reflecting the inclusion of tax liabilities from our CGR Catanduva landfill under this program, which was previously being settled through another tax amnesty program.

The main impacts on the statement of profit or loss in relation to entering into this program in 2018 were: (i) inclusion of additional R$46.6 million into the Brazilian Tax Regularization Program as a result of the internal investigation process; (ii) reversal of R$7.7 million deferred tax assets million not used to settle “Income and Social Contribution Taxes” in one of the programs; (iii) accrual of R$11.4 million in interest expenses recorded under “Finance Expenses” reflecting interest accrued on the balance of taxes through the Brazilian Tax Regularization Programs; (iv) the usage of R$89.9 million in tax losses carryforward and other tax credits that were applied in partial settlement of the tax debts under the Tax Regularization Program; and (v) R$54.0 million of taxes excluded from the Brazilian Tax Regularization Program as they were not due or not eligible to be included (which resulted in a R$6 million positive impact on our statement of profit and loss for the year ended December 31, 2018).

2018 Cost Cutting Initiatives

As described elsewhere in this annual report, during the course of 2018, the revenue we generated from our collection business significantly decreased and our liquidity position deteriorated. We are currently focused on executing a number of initiatives aimed at allowing us to improve our liquidity position. In the second half of 2018, the Company implemented certain cost-cutting initiatives, of which the most significant from a cost perspective was a headcount reduction in approximately 13%. We estimate that on an annual basis, such measures resulted in a reduction of employee compensation costs of R$2.5 million. As a result of the headcount reduction, in the year ended December 31, 2018, we incurred in severance costs of R$15.7 million, which were paid in December 2018.

Divestments and Asset Sales

As part of our efforts to streamline our operations, we have since 2014 divested of certain assets that negatively impacted our margins and did not align with our strategic vision, together with the sale of other assets to generate additional liquidity. These divestments and other transactions have had a significant impact on our results of operations, serving as a salient factor driving variations between periods. A summary of our significant asset sales is set forth in “Item 4.A. Information About the Company—History and Development of the Company—Recent Divestments and Acquisitions.” It is possible that we may have to sell additional assets in the future to improve our liquidity position.

In addition, as discussed below under “—Principal Components of Our Statement of Profit or Loss—Discontinued Operations,” during the periods included in this annual report, we classified certain of our operations as discontinued operations. Our results for the years ended December 31, 2018, 2017 and 2018 included in this annual report have been restated to reflect the reclassification of the relevant operations as discontinued operations.

How We Generate Revenue

We generate revenue primarily by providing cleaning, collection, disposal and treatment services to municipal, residential, waste collection companies and C&I customers. Our remaining revenue is generated from soil treatment and siteclean-up for oil and gas clients,co-processing, landfill biogas energy generation operations, recycling, reverse manufacturing and the sale of carbon credits.

Revenue from our collection and urban cleaning operations consists of fees we receive from municipal and C&I customers pursuant to short and medium-term contracts through which we collect based on the weight collected or, less commonly, a fixed monthly fee, as is the case for our Salvador contract. The pricing of our municipal contracts is established at the time of execution as part of the competitive bidding process based on factors such as anticipated collection frequency, type of collection equipment needed, number of employees needed to provide service, anticipated type and weight of the waste collected, distance to the transfer station or disposal facilities and disposal costs. The pricing model for our C&I customers differs from the process for public clients, since it does not involve public bidding processes. Instead, contracts are negotiated privately between us and our prospective customers. Once an initial inquiry is made, our pricing team analyzes several factors based on the scope and type of services to be provided, as well as margin and other financial requirements, in order to arrive at the specific pricing terms to be negotiated with the prospective C&I client. Our municipal customer relationships are generally supported by exclusive contracts ranging from three to five years in initial duration with subsequent renewal periods when permitted by the contract agreement. Our contracts with our C&I customers are typically from one to three years in initial duration with subsequent renewal periods. The majority of our contracts with our customers have annual price escalation clauses that are tied to inflation.

Our landfills generate revenue from disposal and tipping fees. Revenue from our landfill operations consist of fees which are generally based on the type and weight of waste being disposed. While, as a result of the competitive bidding process, our landfill contracts with our municipal customers typically stipulate a fixed amount per ton of waste disposed, the amount invoiced to municipal customers on a monthly basis varies based on actual volume of waste disposed. Due to our high rate of internalization pursuant to which we currently dispose of approximately 55% of the total waste collected for municipal clients in our own landfills, there is a significant degree of overlap between our customers in the Collection & Cleaning Services segment and Landfills segment. Collections and disposal services are generally provided pursuant to separate agreements with different pricing models.

Revenue from our Oil & Gas operations was derived from the fees we receive for site cleanup of oil and gas projects and, specifically, remediation of areas contaminated by hydrocarbons. Our main customer in this segment was Petrobras with whom we no longer have active contracts.

Revenue derived from ourco-processing operations consists primarily of treatment fees that we receive from industrial customers based on the type and weight of the hazardous waste being treated. While we receive fees by the waste generators for the treatment of materials used forco-processing, we do not generate additional revenues in selling the fuel byproduct, which we give, without charge, to private industrial companies to use as fuel for industrial ovens.

Revenue derived from our energy-generation activities consists of the proceeds we receive from the sale of energy we produce from biogas. Our landfill operations naturally produce methane as well as other biogases from the decomposition of organic compounds. We capture these biogases using drains installed throughout our landfills, channeling them to processing plants through a gas network interconnecting the drains. At our power plants, these biogases go through a process of filtration and cooling to fuel the turbines that burn biogas and generate electricity. Of the energy produced as a result of this process, approximately 80% is sold pursuant to power purchase agreements (“PPAs”), which are structured as take or pay contracts with long-standing customers pursuant to which we are required to deliver a certain amount of electricity at set intervals, while the remaining approximately 20% is sold on the spot market.

Revenue from our recycling operations consists of treatment fees as well as the sale of products produced from construction and demolition waste to participants in the construction industry.

Revenue from our reverse manufacturing operations consists of treatment fees as well as the sale of the component parts of complex electronic products, such as steel, plastics and electronic parts, that are the byproduct of our disassembly of such products.

Carbon credit revenue consists of our sale of a tradable certificate or permit representing the right to emit carbon dioxide to carbon emitters. Our landfill operations produce biogas, which we burn in high-temperature flares at our facilities to convert into carbon dioxide. As methane is a greenhouse gas that has approximately 21 times the heat-trapping capacity of carbon dioxide, our process of reducing methane into carbon dioxide generates carbon credits. We sell the carbon credits to the NEFCO Nordic Environment Finance Corporation (“NEFCO”), pursuant to a procurement contract that expires in 2020, which NEFCO uses in order to meet Norway’s requirements under the second commitment period of the Kyoto Protocol.

Until December 31, 2017, we used to recognize revenue to the extent economic benefits are likely to be generated and when such amount can be reliably measured and, accordingly, revenue recognition did not necessarily correspond to cash flow. Revenue was measured at fair value of payments received or receivable and were recorded in our statement of profit and loss net of certain sales taxes and other discounts.

On January 1, 2018, IFRS 15 – Revenue from Contracts with Customers came into effect, which establishes a five-step model to account for revenue arising from contracts with customers and requires that revenue be recognized at an amount that reflects the consideration to which the entity expects to be entitled in exchange for transferring good or services to a customer. The five steps are as follows: (i) identification of the contract with the client; (ii) identification of performance obligations; (iii) determination of transaction price; (iv) allocation of transaction price; and (v) income recognition upon satisfaction of performance obligation. Considering the above-mentioned aspects, revenues shall be recorded at the amount that reflects the Company’s expectation of receiving in consideration of the products and financial services offered to customers.

Revenue from services

•

Collection & Cleaning Services: Revenue from Collection & Cleaning Services is recognized when the service is provided. The Company measures the provided service by the transaction price the Company expected to be entitled to.

•

Landfills: Waste that cannot be reused is sent for the most appropriate final disposal, in sanitary landfills. The Company operates 12 landfills across Brazil, serving public and private entities. Revenue is recognized when the disposals are received in the Company’s landfills. The Company measures the waste disposed in the landfills by the transaction price the Company expected to be entitled to.

•

Value Recovery: Value Recovery services are related to a series of solutions that ensure the maximum use of the waste, with its reuse or search for new technology to recycle the materials. Revenue is recognized when the service is provided. The Company measures the provided service by the transaction price the Company expected to be entitled to.

•

O&G: Revenue from services contracts provided to the Oil & Gas industry is recognized when the service is provided. The Company measures the provided service by the transaction price the Company expected to be entitled to.

Revenue from the sale of products

Revenue from the sale of products refers to the sale of scrap, fuel gas, carbon credits and electric power. For the sale of products, revenue is recognized when the performance obligations is satisfied at the time the control of the product sold is transferred to the customer, usually at the time of receipt and acceptance.

The gross income is less rebates and discounts and eliminations of income between related parties and adjustment to present value. For further information, see “Adoption of New IFRS Accounting Standards” below.

Summary of Our Trade Accounts Receivable Policy

Accounts Receivable Policy for C&I Customers

Our trade accounts receivable collection policy with respect to our C&I customers is as follows:

•

Trade accounts receivable that are three days overdue result in a notification informing the customer of the balance and requesting payment;

•

Trade accounts receivable that are seven days overdue result in a second notification informing the customer of the overdue balance and requesting payment, subject to suspension of the services being provided;

•

Trade accounts receivable that are ten days overdue result in suspension of the services being provided, as well as a third notification to the client;

•

Trade accounts receivable that are more than 15 days overdue are result in a fourth notification informing the customer of the overdue balance and requesting payment, subject to being reported to the local credit bureaus;

•

Trade accounts receivable that are 30 days overdue are reported to the local credit bureaus and result in a notification informing the customer of the balance, requesting payment and reiterating the suspension of the services; and

•

Trade accounts receivable that are 45 or more days overdue are forwarded to our legal department to consider legal action, which may involve a collection demand in court.

Our contracts with our C&I customers typically provide for payment within 30 days from the date of the invoice, although invoicing arrangements can vary on acase-by-case basis based on the profile of the municipality. Our experience is that our C&I customers typically pay for current invoices between 30 to 45 days from the date of the invoice, but significant variation exists across the spectrum of our customers. As of December 31, 2018, accounts receivable from C&I customers represented approximately 14.0% of our total accounts receivable balance (14.2% as of December 31, 2017).

Accounts Receivable Policy for Public Entity Customers

Our trade accounts receivable collection policy with respect to our municipal and other public entity customers is as follows:

•

Trade accounts receivable that are 45 days overdue result in a notification informing the customer of the balance and requesting payment;

•

Trade accounts receivable that are 60 days overdue result in a second notification informing the customer of the overdue balance and requesting payment;

•

Trade accounts receivable that are 90 days overdue result in a third notification requesting payment within 72 hours, subject to suspension of the services being provided (to the extent permitted under Brazilian law); and

•

Trade accounts receivable that are more than 90 days overdue are forwarded to our legal department to consider legal action, which may involve a collection demand in court. We typically attempt to simultaneously negotiate alternative payment arrangements with our defaulting public entity customers to incentivize payment, which arrangements can vary on a case by case basis, but do not involve forgiveness of any portion of the principal amount due to us. Generally, we will renegotiate the payment schedule, allowing delinquent customers to pay the full principal amount due in installments over a period of 24 to 60 months, sometimes with interest or inflation adjustments. Failure to reach agreement with the customer to settle the debt could result in suspension of the services being provided (to the extent permitted under Brazilian law).

Our contracts with our public sector customers typically provide for payment within 30 days from the date of the invoice, although invoicing arrangements can vary on acase-by-case basis based on the profile of the municipality. Our experience is that our customers typically pay for current invoices between 30 to 45 days from the date of the invoice, but significant variation exists across the spectrum of our customers. As of December 31, 2018, accounts receivable from public sector customers represented approximately 87.0% of our total accounts receivable balance (85.8% as of December 31, 2017).

Significantly late payments by public entity customers, such as municipalities, are a frequent occurrence in the Brazilian waste management industry. Pursuant to Brazilian Law No. 8,987/95 and Law No. 8,666/93, public services may be suspended in the event the payment for past services is past due for more than 90 days, unless the suspension could result in severe disturbances of the public order. In addition, under the Brazilian Constitution, as well as Law No. 11,101/05, municipalities are unable to declare bankruptcy and forfeit on their obligations. As a result of this, we do not typically write off accounts receivable from our public entity clients, as there is an expectation that accounts will eventually be settled following renegotiation and, if necessary, court intervention, even if such payment may be delayed for years. In addition, in extreme circumstances, the Brazilian Constitution allows the intervention of the state to settle unpaid obligations at the municipal level.

In addition, Brazilian Complimentary Law No. 101/00 and Law No. 4,320/64, which regulate public budgets, permit a governmental entity to transfer unpaid amounts in any given year to the subsequent year’s budget. Such practice underlies our policy of not writing off municipal accounts, as any overdue amounts will be presumably budgeted for the subsequent period until settled. In addition, as an additional form of protection, creditors owed amounts by governmental entities can claim such unpaid amounts through legal actions by obtaining a government-backed credit document called a “precatório” through which the petitioning creditor can guarantee that the claimed amounts will be included in the relevant governmental entity’s budget until these amounts are settled. Governmental entities must consider in their annual budgets the payment of claims for which an officialprecatório has been issued, with actual payments typically made in the order thatprecatórios are received. Default of the obligation to pay aprecatório may trigger the intervention of the state to pay on behalf of the municipality.

In our experience, the general macroeconomic environment has a significant impact on the financial condition of municipalities, with the rate of payments on trade accounts receivable decreasing significantly during periods of economic downturn as municipalities face decreasing revenues. For example, the extended recession that Brazil experienced starting in 2014 and from which it is still recovering, has increased budgetary pressures on Brazilian municipalities and significantly increased payment delays by our public entity customers.

In addition, we experience a higher rate of payments on our trade accounts receivable from municipalities during the first three months of each year, as Brazilian municipalities receive an annual transfer of federal funds at the beginning of the year. In the first quarter of the year, municipalities typically pay on time and, in addition, often make payments on past due amounts, if any. The rate of payments on trade accounts receivable progressively decreases as the year progresses, with the fourth quarter of each year exhibiting the lowest rate of payments on trade accounts receivable. We also experience a lower overall rate of payments on our trade accounts receivable from municipalities during election years and during the first quarter of the years following elections due to shifting budgetary priorities. Municipal elections are held country-wide at the same time every four years, and the last such elections were held at the end of 2016. In line with past experience, our collections were negatively impacted in the last quarter of 2016 and the first quarter of 2017.

Our strategy of engaging public entity clients in an attempt to renegotiate the payment schedule of overdue balances has helped to incentivize payments on trade accounts receivable and allowed us to increase our rate of collections from delinquent customers. By permitting certain delinquent municipal customers to pay their full overdue principal amounts in installments, we believe we are able to recover such amounts while at the same time enabling our customers to continue meeting their obligations under current invoices. The renegotiation process for payment of accounts receivable that are overdue by 360 days or more is time-intensive and can take years to be concluded.Trade accounts receivable are recorded net of allowances for doubtful accounts. For more information on our policy relating to allowances for doubtful accounts, see “—A. Operating Results—How We Generate Revenue—Allowance for doubtful accounts” above.

Competitive Bidding Processes and Revenue Impact

Our contract with the municipality of São Paulo

We have been servicing the São Paulo contract through Soma since 2011. Our contract with the municipality of São Paulo for urban cleaning and street sweeping services represented approximately 25.5% of our revenues in 2018 (29.1% of our revenues in 2017). This contract expired in the end of 2017, and we are currently providing urban cleaning services to the city of São Paulo pursuant to a temporary contract. The temporary contract was first entered into on December 15, 2017 and expired in June 2018. On June 12, 2018, we further extended the temporary contract until the end of 2018. In December 2018, we further extended the contract which is now set to expire in June 2019, subject to earlier termination by the municipality. However, the extended temporary contract introduced in June 2018 certain significant changes to the contractual arrangement. Most significantly, under the extended temporary contract, the city of São Paulo has been divided into six separate parcels for urban cleaning, whereas under the previous contract the city had been divided into two parcels only. We, through Soma, were awarded only two parcels under the extended temporary contract, which reflects a significant decrease of our service area, since we previously serviced one of the only two parcels. As a result these changes, monthly revenues under the extended temporary contract decreased approximately 40% starting in June 2018 and as a result our revenues from the contract with the municipality of São Paulo for urban cleaning and street sweeping services decreased to approximately 31.8% of our revenues in 2018.

After a series of delays, a new bid for the São Paulo contract was initiated in October 2018, in which the Company participated, and is expected to be finalized in June 2019. In connection with the bidding process, São Paulo has divided the urban cleaning contract into six separate parcels, in line with the extended temporary contracts entered into in June 2018. The Company was not the bidder with the lowest price for any of the six parcels and has been informed that its temporary emergency contract will terminate on June 1, 2019. Therefore, we expect to provide services under the terms of the temporary emergency contract until its expiration. The loss of the São Paulo cleaning contract will result in a significant reduction in our revenues, which will have an adverse impact on us.

A relevant part of our operational structure is designed to serve the São Paulo contract and, upon its termination, we will likely be required to significantly reallocate resources, including the potential early termination of employees currently servicing this contract and/or closure of certain facilities and projects solely related to our current operations in São Paulo, all of which could have the effect of increasing costs in the short-term. Furthermore, given the medium and long term nature of the majority of our contracts, we will not have the flexibility to immediately offset a decrease in revenues by increasing prices. Given the staggered timing of attractive competitive bidding opportunities occurring only on an intermittent basis as existing contracts come due, we will likely face challenges to quickly replace the lost revenues with new collections business. Given the size of the city of São Paulo, being the largest city in Brazil in terms of population according to 2017 IBGE data, we would likely have to secure several smaller contracts to replace the revenues lost under the contract. The significant loss of revenues could, in turn, impact our ability to comply with the covenants under any of our indebtedness or make payments as they come due.

Our contract with the municipality of Curitiba

Critical Accounting Policies and Estimates

Significant accounting policies and estimates are those that are important both to the presentation of our financial condition and results of operations and that require our management’s complex or subjective judgments, often as a result of the need to prepare estimates about matters that are inherently uncertain. As the number of variables and assumptions that affect the future resolution of uncertainties increases, these judgments become even more subjective and complex. In order to provide an understanding of how our management forms its judgments about future events, including the variables and assumptions underlying the estimates and the sensitivity of those judgments to different circumstances, we have identified the following significant accounting practices and estimates:

Allowance for doubtful accounts

As described under “—Adoption of New IFRS Accounting Standards—IFRS 9 Financial Instruments”below, IFRS 9 impacted our policy for recording allowance for doubtful accounts pursuant to which we now apply a simplified approach and record lifetime expected losses on all of our accounts receivable from both private C&I and public sector customers. Prior to the application of IFRS 9, an allowance for doubtful accounts was recorded for trade accounts receivable for all customers that were overdue by more than 360 days from their original maturity dates.

In assessing lifetime expected losses for our accounts receivable, we conducted a historical study of the behavior of our portfolio, creating a risk matrix by age range, and we now record allowance for doubtful accounts based on risk category in this matrix. Other factors that are considered when recording an allowance for doubtful accounts include a risk analysis conducted on each client’s portfolio, guarantees obtained, settlement agreements entered into with clients and probabilities of collection.

Our contracts with our private C&I and public sector customers typically provide for payment within 30 days from the date of the invoice, although invoicing arrangements can vary on acase-by-case basis based on the profile of the customer or municipality. Our experience is that our customers typically pay for current invoices between 30 to 45 days from the date of the invoice, but significant variation exists across the spectrum of our customers. As of December 31, 2018, accounts receivable from public sector customers represented approximately 87.0% of our total accounts receivable balance (85.8% as of December 31, 2017).

Specifically in relation to public sector customers, there is an element of seasonality with regard to payments, with a higher rate of payments during the first months of each year, as Brazilian municipalities receive an annual transfer of federal funds at the beginning of the year. As a result, in the beginning of the year, municipalities typically pay on time and, in addition, often make payments on past due amounts. On the other hand, the rate of late payments increases in the last quarter of the year, when municipalities are usually short of financial resources.

The payment of accounts receivable that are overdue will be renegotiated and the renegotiation process often takes a significant period of time (at times years) to be concluded and, in the meantime, we record an allowance for doubtful accounts based on this historical study of the behavior of the portfolio.

The allowance for doubtful accounts is recorded in selling expenses, net of recoveries, and are fully reversed whenever a debt is fully paid or partially reversed if its payment is effectively renegotiated through an installment payment arrangement. Trade accounts receivable are recorded net of allowances for doubtful accounts.

In many cases, municipalities with whom we have overdue receivables enter into agreements with us, which we refers to as the “formal recognition of debts”, whereby we accept to renegotiate the timing of payment of their overdue debts, sometimes forfeiting penalties and part of the interest contractually due on late payments. When we have sufficient evidence that our customers are committing to their revised payment schedules (at least two months of timely payments), we reverse the corresponding previously recognized allowance for doubtful accounts while continuing to monitor the payment of this negotiation. These renegotiations rarely forfeit a principal amount of debt due and often include an inflation adjustment for the overdue amounts.

The balance of allowance for doubtful accounts increases as the historical payment behavior of clients worsens with a corresponding effect on risk classification in the matrix and such balance may decrease mainly for two reasons affecting the assessment of historical payment behavior: (i) payments are received on accounts that we recorded an allowance recorded, and (ii) upon the formal renegotiation of and the reaching of an agreement with the debtor relating to the amounts overdue.

Upon application of IFRS 9, we recorded a R$3.5 million decrease in the allowance for doubtful accounts on January 1, 2018.

Impairment ofnon-financial assets

We monitor the carrying value of our long-lived assets for potential impairment and test the recoverability of such assets whenever events or changes in circumstances indicate that their carrying amounts may not be recoverable and, at least, on a yearly basis. These events or changes in circumstances, including management decisions pertaining to such assets, are referred to as impairment indicators. Typical indicators that an asset may be impaired include (i) a significant adverse change in legal factors in the business climate, (ii) an adverse action or assessment by a regulator and (iii) a significant adverse change in the extent or manner in which a long-lived asset is being utilized or in its physical condition. Impairment loss exists when the book value of an asset or cash-generating unit exceeds its recoverable amount, which is the higher of fair value less cost to sell and value in use. We calculate fair value less costs to sell based on information available about the current market for similar assets, less additional costs to dispose of the asset. Meanwhile, we calculate value in use based on discounted cash flow model, which does not consider restructuring activities that we have not yet committed to or significant future investments that will improve the asset subject to testing. The recoverable amount is, therefore, sensitive to the discount rate used in the discounted cash flow method, as well as expected future cash receipts and growth rate used for projection purposes.

For the year ended on December 31, 2018, 2017 and 2016, we recorded impairment charges on goodwill and other intangibles and fixed assets of R$547.7 million, R$37.2 million and R$44.8, respectively.

During 2018, the waste collection business of Estre presented a rapid deterioration, mainly due to the market conditions including strong margin compression. Declining margins in this business made it unattractive for us to renew certain of our collection contracts. Since we do not expect a recovery of market conditions in the future, we have decided to exit gradually from this market segment and such strategy was reflected in the estimated future cash flow used for impairment testing, which resulted in impairment losses recognized in 2018. See note 12 to our audited financial statements included elsewhere in this annual report.

Provision for legal proceedings

We are subject to various legal proceedings and claims, the outcomes of which are subject to significant uncertainty. We established provisions for tax, civil and labor contingencies. We determine whether to disclose or accrue for loss contingencies based on an assessment of whether the risk of loss is remote, possible or probable and whether it can be reasonably estimated. Our assessment of the likelihood of loss is based on our evaluation of available evidence, the legal framework, available case laws, recent court rulings and analysis of their relevance, as well as the opinion of external legal counsel. Our provisions are reviewed and adjusted to take into consideration changes in circumstances such as applicable statutes of limitation, conclusions of tax audits or additional exposures identified based on new issues or court decisions. The settlement or resolution of these proceedings may result in amounts different from those estimated, due to inaccuracies inherent in the assessment process. We review our estimates and assumptions on at least an annual basis.

We record losses related to contingencies in cost of operations or selling, general and administrative expenses, depending on the nature of the underlying transaction leading to the loss contingency.

Fair value of financial instruments

We have established a process for reviewing all significant fair value measurements, including Level 3 fair value measurements. When measuring the fair value of an asset or a liability, we use observable market information. Fair values are classified at different levels in a hierarchy, as follows:

•

Level 1—quoted prices are available in a market with high liquidity for identical assets and liabilities at the date of the financial statements, consisting mainly of financial instruments traded on a stock exchange.

•

Level 2—prices used are different from prices quoted at Level 1, although they are directly or indirectly observable at the date of the financial statements. In this modality, financial instruments are valued using some type of modeling or other valuation methodology based on current market values, volatility, future prices, time values or other economic measurements.

•

Level 3—the sources of price information used include sources that are generally less observable, but which can be based on objective sources. These sources can be used with methodologies internally developed by us.

Landfill accounting and provision for landfill closure

As part of our environmental obligations in relation to landfills, we recognize a provision for landfill closure as a corresponding entry of a property, plant and equipment item, and depleted based on landfill usage volume as a percentage of a total licensed capacity. Our provision for landfill closure is recognized at present value and accreted as landfill capacity is used, and accreted over time for the time value of money. In determining the amount of the provision, assumptions and estimates are made in relation to discount rates, the expected cost for landfill closure and future maintenance of the site and the expected timing of these costs.

The significant accounting aspects are summarized below:

•

Decommissioning costs are recorded for at the present value of expected costs to settle the obligation using estimated cash flows and are recognized as part of the cost of the relevant asset;

•

The cash flows are discounted at apre-tax long-term risk-free rate that reflects the risks specific to the decommissioning liability. The unwinding of the discount is expensed as incurred and recognized in the statement of profit or loss. The estimated future costs of decommissioning are reviewed annually and adjusted as appropriate. Changes in the estimated future costs, or in the discount rate applied, are added to or deducted from the cost of the asset;

•

The estimated costs are recorded taking into account the present value of the obligation, discounted to an average long-term risk-free rate of 1%; and

•

Cost estimates are reviewed annually, with the consequent review of present value calculation, adjusting the amounts of assets and liabilities already accounted for.

Landfill Cost Basis. Costs capitalized and included in our landfill assets include engineering designs and plans, earth-moving and excavation costs, construction, safety equipment, costs of obtaining environmental licenses and operating permits, installing piping for collection of biogas and installing lining material that prevents leachate leaking into the soil. As landfill capacity is used, periodically further lining is installed to seal layers or sections of the landfill, which we refers to as the “implementation of cells.”

Costs that we expect to incur upon exhausting capacity at each of our landfills includes the ongoing maintenance costs such as soil and air monitoring, leachate drainage and disposal and site security.

Costs capitalized into our landfill assets are recognized when incurred, and depreciated from the moment that they are in the condition in which they are able to be used, in line with IAS 16.55.

The discount rate used to bring future estimated landfill closing costs to present value is ourpre-tax weighted average cost of capital, which we believe represents an appropriate rate reflecting market assessments of the time value of money and the risks specific to the liability, in line with IAS 37.47.

Amortization and Accretion. Our landfill assets are amortized over their expected useful lives calculated based on the usage volume of the landfill. Our provision for landfill closure is accreted as the capacity of each landfill site is used. The amount accreted is the total estimated closing and ongoing future operating costs expected to be occurred once landfill capacity is exhausted, discounted to present value, and divided by the usage of capacity in the period. The provision is further accreted for the passing of time as the expected date of closing approximates.

Licensed capacity is set by the environmental regulatory agencies, according to each landfill’s location, environmental and geological attributes.

Impairment Considerations. Landfill assets are grouped together with other assets including buildings and operating equipment in a given geographical area that form a cash generating unit (CGU), as these operate in an integrated manner serving waste collection contracts in nearby municipalities.

Our CGUs have goodwill allocated to them and are tested annually for impairment by comparing their carrying values to their recoverable amounts which are determined by the CGUsvalue-in-use based on projections of discounted future cash flows to be generated from the operations of each CGU.

In the event that an impairment test finds that the recoverable amount of a CGU is lower than its carrying amount, the assets of the CGU are impaired by firstly allocating any charges to goodwill, and subsequently to the remaining assets of the CGU.

Deferred tax assets

Deferred tax assets are recognized for all unused tax losses to the extent that it is probable that taxable profit will be available against which the losses can be used. Such assessment requires significant professional judgment as to determine the deferred tax asset amount to be recognized based on probable term and future taxable profit levels, in addition to future tax planning strategies. We did not recognize any deferred tax assets of December 31, 2018.

Fair value measurement of stock option

Estimating fair value for share-based payment transactions requires determination of the most appropriate valuation model, which depends on the terms and conditions of the grant. This estimate also requires determination of the most appropriate inputs to the valuation model including the expected life of the share option, volatility and dividend yield and making assumptions about them.

We use the Black & Scholes model to calculate the fair value of the shares that are part of the stock option plan approved by our Board of Directors on September 15, 2015. We have made an initial assessment of the estimates on the amount of shares to be issued. The impact of the valuation was recognized as an expense, with the corresponding adjustment in equity.

Principal Components of Our Statement of Profit or Loss

For a discussion of our revenue from services rendered, see “—A. Operating Results—Results of Operations—Revenue From Services Rendered” below.

Costs of services

Our cost of services include the following main costs:

•

payroll, charges and benefits costs, which consist of salaries and wages, health and welfare benefits, incentive compensation and payroll taxes;

•

other expenses, which include expenses such as outsourced labor costs, certain maintenance and repair costs.

Operating income/expenses

Other operating income and expenses consists of selling, general and administrative expenses, including salaries, legal and professional fees. Salary expenses include salaries and wages, health and welfare benefits and incentive compensation for corporate and field general management, field support functions, sales force, accounting and finance, legal, management information systems and clerical and administrative departments. Certain depreciation, amortization and depletion costs as well as leasing and equipment maintenance costs are allocated to general and administrative expenses to the extent related to corporate activities, such as the buildings and facilities serving administrative functions, computers and peripherals, furniture and fixtures as well as our commercial sales fleet. In addition, we allocate provisions for legal proceedings under general and administrative expenses insofar as our management determines, based on the advice of internal and external counsel, that the chance of loss is probable, and we also record expenses for the allowance for doubtful accounts under selling expenses (for additional information, see “Item 8.A. Financial Information—Consolidated Statements and Other Financial Information—Legal and Administrative Proceedings and Investigations”). Other expenses include rent and office costs, fees for professional services provided by third parties, marketing, directors’ and officers’ insurance, entertainment and charitable contributions for social causes, primarily throughInstituto Estre.

Our other operating income (expenses) consists primarily of impairment charges, write-offs, capital gains and losses, other gains and losses from the sale of property, plant and equipment and investments and tax credits.

We also record the share of profit of an associate under operating income/expenses, consisting mainly of results from our investments in the following entities for the periods indicated:

(1)

In connection with the Transaction, on December 21, 2017, we entered into three definitive agreements for the transfer of our equity interests in Loga, Attend and Terrestre to a vehicle controlled by the Company’s former shareholders for a nominal fee. These agreements were subject to customary conditions precedent, such as regulatory approvals and other third-party consents. As of December 28, 2018, all three transactions have been completed.

(2)	On December 14, 2018, we concluded the sale of our 50% interest in CGR Catanduva – Centro Ger. Resíduos Ltda. to our business partner – SHZ Participações Ltda.

(3)

In April 2017, Cavo Serviços e Saneamento S.A. acquired the remaining 46% of Unidade de Tratamento de Resíduos S.A. and started consolidating 100% of its results. On August 22, 2017, Unidade de Tratamento de Resíduos S.A. merged into Cavo Serviços e Saneamento S.A. and no longer independently exists.

Finance income and costs

Finance income is mainly comprised of interest income from inflation adjustments on recoverable tax credits and social contribution tax losses and withheld social security (Instituto Nacional do Seguro Nacional) (“INSS”), as well as interest income from the renegotiation with customers. In addition, we record finance income from invested funds and other investments.

Finance costs are comprised primarily of inflation adjustments and interest on debentures and other loans as well as other interest costs associated with late payments to suppliers and taxes. In addition, certain discounts given to customers are recorded as finance costs.

Income tax and social contribution

Income tax and social contribution, both current and deferred, are calculated at a rate of 15%, plus an additional 10% on annual taxable income in excess of R$240,000 for income tax and 9% on annual taxable income for social contribution, taking into account the offsetting of tax loss carry-forwards and negative base of social contribution, limited to 30% of the taxable income each fiscal year.

Income tax and social contribution expenses consist of current and deferred income taxes. Both current and deferred taxes are recognized in our results of operations, except for those related to transactions or items directly recognized in shareholders’ equity or other comprehensive income.

Current taxes represent the expected tax payable or receivable on the taxable profit or loss for the year, at applicable tax rates enacted or substantively enacted on the reporting date and any adjustment to the taxes payable in relation to prior years. Our management regularly assesses the tax positions in circumstances in which tax regulations require interpretation, and sets up provisions when necessary.

Deferred tax is recognized with respect to the temporary differences between the book values of assets and liabilities and their tax basis.

The carrying amount of deferred tax assets is reviewed at each statement of financial position date and reduced to the extent that it is no longer probable that taxable profits will be available to allow all or part of the deferred tax asset to be utilized. Deferred tax assets written off are reviewed at every statement of financial position date and recognized to the extent that it is probable that future taxable profit will allow deferred tax assets to be recovered.

Deferred tax assets and liabilities are measured at the tax rates expected to apply in the year when the asset is realized or the liability settled, based on tax rates (and tax laws) that have been enacted at the statement of financial position date.

Our effective tax rate is principally impacted by the unavailability of sufficient future taxable income against which to recognize deferred tax assets, pursuant to IAS 12.24 and 34. This causes volatility in our effective tax rate as we are not able to recognize deferred tax assets on deductible temporary differences, such as those generated by (i) the recognition of impairment losses (which are only deductible for income tax purposes upon sale or disposal of the impaired asset), (ii) provisions for doubtful accounts and for contingencies, or (iii) our tax losses for the period. Should our assessment of the probability of available future taxable income change such that we are able to recognize deferred tax assets on all of our deductible temporary differences, the variances in our effective tax rate between periods would likely be lower.

Discontinued Operations

We classify assets held for sale as discontinued operations. The criteria for classification of items held for sale are considered as having been met only when a sales transaction is highly probable to occur and when such items are available for immediate sale in the present condition. Discontinued operations are excluded from profit or loss of continuing operations, and presented as a single amount in profit or loss after taxes under discontinued operations in the statement of profit or loss. In 2017, we classified as discontinued operations CGR Dona Juana ESP, in connection with the agency agreement for sale from January 9, 2016, which asset was eventually sold on November 20, 2018. In addition, in 2017, we also classified results from Attend Ambiental Ltda., Terrestre Ambiental Ltda. and Logística Ambiental de São Paulo (Loga) as discontinued operations in connection with the Transaction, in which we entered into three definitive agreements for the transfer of our equity interests in Loga, Attend and Terrestre to a vehicle controlled by the Company’s former shareholders for a nominal fee. Furthermore, in 2017, we also classified results from Leccaros Participações S.A. as discontinued operations in connection with the completion of our sale of that entity on April 23, 2018. As of December 31, 2017 and 2018, none of the entities referred to above were consolidated into our financial statements.

On December 06, 2018, the Company and our board of directors approved the plan to sell the Company’s energy business. Negotiations with certain investors already started and we currently expect to dispose of the operating facilities of our energy business within the one year.

Our energy business comprises our subsidiaries Guatapará and Estre Energia, which directly holds 99.99% ownership of Curitiba Energia SPE Ltda. (“Curitiba Energia”) and SPE Tremembé Energia Ltda. (“SPE Tremembe”), SPE Paulinia Energia Ltda. (“Paulinia”) and Piratininga Energia e Participações Ltda. (“Piratininga”), with Paulinia and Piratininga still inpre-operational stages. The remaining 0.01% of Curitiba SPE, SPE Tremembé, Paulínia and Piratininga are held directly by the Company. Enc Energy Brasil Participações S.A. (“Enc Energy”) which is a minority shareholder in our energy generation business (comprised of Estre Energia Renovável Participações S.A. (“Estre Energia”) and its subsidiaries and Guatapará Energia S.A. (“Guatapara”)), with 10% ownership.

As of December 31, 2018, the energy business was classified as a disposal group held for sale and as a discontinued operation. As such, the results of operations our energy business are no longer presented within our Value Recovery segment. Notes 1.5.1 and 10.2 of our financial statements included in this annual report includes financial information on the results of our energy business for the years ended December 31, 2018, 2017 and 2016. The results for our energy business for the year ended December 31, 2018 are included in our consolidated statement and profit and loss for the year ended December 31, 2018 under “profit after income and social contribution tax from discontinued operations”.

Our consolidated statement of profit and loss for the years ended December 31, 2017 and 2016 have been restated to reflect the reclassification of our energy business as discontinued operations.

Adoption of New IFRS Accounting Standards

The IASB, or other regulatory bodies, periodically introduce modifications to financial accounting and reporting standards under which the Registrant prepares its audited financial statements. Recently, a number of new accounting standards and amendments and interpretations to existing standards have become effective, including from January 1, 2018, IFRS 9—Financial Instruments (“IFRS 9”) and IFRS 15—Revenue from Contracts with Customers (“IFRS 15”) and, from January 1, 2019, IFRS 16—Leases (“IFRS 16”).

We have adopted these new accounting standards on the effective date required and, therefore, the audited financial statements included in this annual report as of and for the year ended December 31, 2018 reflect the application of IFRS 9 and IFRS 15 but do not yet reflect the application of IFRS 16. For more information on our analysis and evaluation on the impact of these new accounting standards, please see note 2.22 of our audited financial statements included elsewhere in this annual report.

IFRS 9 Financial Instruments

In July 2014, the IASB published IFRS 9, which established, among other matters, principles that apply to the classification, measurement and recognition of financial instruments, and covers requirements for the classification, measurement, impairment andde-recognition of financial assets and financial liabilities, together with the introduction of a new hedge accounting model. We adopted IFRS 9 on January 1, 2018 and did not restate comparative information. We did not register any significant effects on our statement of financial position or equity as result of the application of the classification and measurement requirements of IFRS 9.

Following the application of IFRS 9, we continue to measure at fair value all financial assets currently held at fair value. Trade accounts receivable and othernon-current financial assets previously classified as loans and receivables are held to collect the contractual cash flows representing solely payments of principal and interest. These are now classified and measured as debt instruments at amortized cost.

The main impacts that we identified based on the application of IFRS 9 relate to impairment. IFRS 9 now requires us to record our expected credit losses on all our financial assets measured at amortized costs and at fair value through other comprehensive income based on 12 months or, depending on the circumstances, through the life of asset. Therefore, it is no longer necessary for the event resulting in a loss to occur in order to recognize it. In assessing the impact of this pronouncement on our accounts receivables, we performed an assessment to segregate our financial assets based on their risk characteristics and counterparts, mainly to separate accounts receivable from private customers and accounts receivable from public customers. In addition, in assessing lifetime expected losses for our accounts receivable, we conducted a historical study of the payment behavior of our portfolio, creating a risk matrix by age range, and we now record allowance for doubtful accounts based on risk category in this matrix. In applying such methodology, we took a simplified approach and recorded the expected credit losses for the life of the account receivables.

Based on our analysis, we recorded a positive impact of R$3.5 million, reflecting a decrease in the allowance for doubtful accounts, with the main factor being the new definition of the default term of the public sector.

For additional information, see note 2.22 of our financial statements included in this annual report.

IFRS 15 Revenue from Contracts with Customers

IFRS 15 was issued in May 2014, and amended in April 2016. IFRS 15 establishes a five-step model to account for revenues arising from contracts with customers. Under IFRS 15, revenue is recognized at an amount that reflects the consideration to which an entity expects to receive in exchange for the transfer of goods or services to a customer.

The Company adopted the modified retrospective transition method, on January 1, 2018.

In adopting IFRS 15, we were required to determine whether there is a significant financing component in our contracts. A significant financing component may exist if the promise of financing is expressly stated in the contract or implied in the terms of payment agreed to by the parties to the contract. In connection therewith, we present the following considerations in relation to the adoption of IFRS 15:

•

Variable consideration – significant financial component: In accordance with IFRS 15, we carried out an analysis related to the existence of a significant financial component for public sector clients, since the average term of effective receipt for this client portfolio is approximately six months. In so doing, we considered the average rate of 8.50% for the discount rate of 2018, which represents the discount rate usually applied by us to calculate present value of ournon-current assets and liabilities. The impact of the adoption of IFRS 15 resulted in an immaterial reduction in equity of R$0.5 million as of January 1, 2018.

•

Contract liabilities—Advance received from customers: For some contracts entered into with customers, we receive advances before the service is rendered. These balances recorded in revenue, when the services are rendered, over an average period of four months. In accordance with IFRS 15, we analyzed whether there is a significant financing component in these contracts, and elected to use the practical expedient provided for in IFRS 15 paragraph 63 and did not adjust the amount promised for the effects of significant financing components in the contracts.

Reversal of revenue: Under IFRS 15, the amount of the consideration may vary due to discounts, rebates, refunds, credits, price concessions, incentives, performance bonuses, penalties or other similar items. We estimated that the effects of discounts and rebates amounted to R$1.9 million at January 1, 2018, and made a corresponding adjustment in the equity statement.

The adoption of IFRS 15 resulted in an impact of R$2.6 million, net of deferred income tax and social contribution of 34%, which was recorded in shareholders’ equity as of January 1, 2018.

For additional information, see note 2.22 of our financial statements included elsewhere in this annual report.

New Accounting Standards Not Yet Adopted

IFRS 16 — Leases

On January 13, 2016, the IASB issued IFRS 16, and it replaces IAS 17,Leases,IFRIC 4,Determining whether an Arrangement contains a Lease,SIC-15,Operating Leases-IncentivesandSIC-27,Evaluating the Substance of Transactions Involving the Legal Form of a Lease.IFRS 16 establishes principles for the recognition, measurement, presentation and disclosure of leases and requires lessees to account for all leases under a singleon-balance sheet model similar to the accounting for finance leases under IAS 17.

The standard includes two recognition exemptions for lessees – leases of‘low-value’ assets (for example, personal computers) and short-term leases (i.e., leases with a lease term of 12 months or less). At the commencement date of a lease, a lessee will recognize a liability to make lease payments (i.e., the lease liability) and an asset representing the right to use the underlying asset during the lease term (i.e., theright-of-use asset). Lessees will be required to separately recognize the interest expense on the lease liability and the depreciation expense on theright-of-use asset.

Lessees will be also required to remeasure the lease liability upon the occurrence of certain events (e.g., a change in the lease term, a change in future lease payments resulting from a change in an index or rate used to determine those payments). The lessee will generally recognize the amount of the remeasurement of the lease liability as an adjustment to theright-of-use asset.

We have adopted these new accounting standards on the effective date required, which was January 1, 2019 and, therefore, the audited financial statements included in this annual report do not yet reflect the application of IFRS 16. We adopted IFRS 16 using the retrospective modified transition method. On January 1, 2019, we recognized aright-of-use asset and a lease liability of R$38.2 million.

For additional information, see note 2.23 of our financial statements included elsewhere in this annual report.

Our Business Segments

Our business operations are organized according to four main business segments: (i) Collection & Cleaning Services, (ii) Landfills, (iii) Oil and Gas, and (iv) Value Recovery. Our management separately monitors operating income (loss) of each of our business segments in making decisions on fund allocation and evaluating performance. While we monitors revenue and allocate costs of services and operating income (expenses) on a per segment basis, our financing (including finance income and expenses) and income taxes and social contribution are managed at the corporate level and, accordingly, are not allocated to our operating segments. Our four business segments are described below:

Collection & Cleaning Services; Our main business segment in terms of revenues through which we collect, transport and temporarily store household waste for residential generators pursuant to short and medium term contracts with municipalities and, to a lesser extent, for C&I customers pursuant to separate contracts with each generator. In addition, a significant portion of our results from this segment involve public cleaning services, including, primarily, street sweeping and upkeep of public spaces to municipalities, including in the municipalities of São Paulo and Curitiba. This segment involves focused logistical planning in terms of routing based on the profiles and conditions of each municipality, with the objective of optimizing efficiency and minimizing risks and environmental impact in transporting waste to the final destination.

Landfill;. Our second largest segment in terms of revenues through which we own and manage treatment centers and landfills and offer use of such facilities to municipal customers, private collection companies and C&I customers for the disposal of their waste (sometimes collected by us as part of our Collection & Cleaning Services segment), including certain hazardous waste and medical waste, for which we receive tipping fees according the volume or weight of the waste to be disposal, which are typically paid on a monthly basis.

Oil & Gas; This segment provides soil treatment and restoration services primarily to one main customer, Petrobras.

Value Recovery; Through this segment, we provide a variety of solutions that seeks to maximize the use of waste through innovative recycling processes. Our main business through this segment is the production and sale of biogas from waste products as well as the production of alternative fuel with high caloric value to the cement industry by combining two or more industrial waste products (hazardous waste), aimed at producing a “blend” (homogeneous mixture), which can be used in industrial furnaces of the cement industry. Through this segment, we also dismantle and repurpose electronic products and engage in more traditional recycling activities serving the construction industry. As of December 31, 2018, the energy business was classified as a disposal group held for sale and as a discontinued operation. As such, the results of operations our energy business are no longer presented within our Value Recovery segment, and our results of operations. Our consolidated statement of profit and loss for the years ended December 31, 2017 and 2016 have been restated to reflect the reclassification of our energy business as discontinued operations.

Costs and expenses allocated to corporate primarily relate to services provided to us at the management and administrative level, including our board of directors, executive officers and upper management team, back office functions, regional administration support, as well as legal and advisory services. In addition, other operating income and expenses (consisting mainly of impairment charges, write-offs and capital gains and losses on the sale of assets) are also allocated here. We do not record revenues at the corporate level.

To eliminate the effects of intercompany transactions among our business segments, we adjust and offset the effect of revenues and expenses relating to services provided by, and received from, our consolidated entities across different business segments, which primarily include revenues and expenses from services provided by our Landfills segment to our Collection & Cleaning Services segment.

For additional information regarding our business segments, see “Item 4.B. Information on the Company—Business Overview—Business Segments.”

Revenue From Services Rendered

Year Ended December 31, 2018 Compared to the Year Ended December 31, 2017

Revenue from services rendered decreased by R$85.2 million, or 6.3%, from R$1,345.8 million in 2017 to R$1,260.6 million in 2018. This decrease was primarily due to (i) a R$66.8 million or 7.2% decrease in revenues from our Collection & Cleaning Services business segment, primarily as a result of a decrease in the volume of services rendered to certain municipalities, and (ii) a R$19.5 million, or 30.6%, decrease in revenues from our environmental services and value recovery revenues. This decrease was partially offset by an increase of R$12.6 million or 12.8% in our C&I collections business revenues, as described below.

The table set forth below presents a breakdown of our revenue from services rendered by business segment for the periods indicated:


	For The Year Ended December 31,
	2018			2017 (restated)
	(in millions of R$)

Collection & Cleaning Services. Revenue from services rendered derived from our Collection & Cleaning Services segment decreased by R$66.8 million, or 7.2%, from R$928.8 million in 2017 to R$862.0 million in 2018. Of our total revenue from services rendered in our Collection & Cleaning Services segment (i) during 2018, R$751.2 million, or 87.1%, was attributable to our public collections business with municipal customers, while R$110.8 million, or 12.9%, was attributable to our C&I collections business, and (ii) during 2017, R$830.6 million, or 89.4%, was attributable to our public collections business with municipal customers, while R$98.2 million, or 10.6%, was attributable to our C&I collections business.

This decrease in revenue from services derived from our Collection & Cleaning Services segment was primarily due to (i) a R$54.6 million decrease as a result of the loss of business of Soma’s urban cleaning contract with the city of São Paulo following certain significant contractual changes in terms of scope and pricing terms introduced from June 2018, (ii) contracts not renewed in 2018, comprising (a) R$13.7 million as a result of the termination of the Aparecida de Goiania contract in April, 2018; (b) R$11.3 million as a result of the termination of the Aracaju contract in July 2018; (c) R$8.3 million as a result of the termination of the Maceio contract in November, 2018, and (d) R$4.3 million as a result of the termination of the São José dos Campos contract in February 2017. This decrease in revenues from our public Collection & Cleaning Services was partially offset by an increase of R$12.6 million in revenue from services in our C&I collection business performance as a result of new clients contracts. For additional information, see “Item 3.D. Key Information—Risk Factors—Risks Related to Our Business—A significant portion of our revenue is derived from a small number of customers, and partial or full loss of revenues from any such customer may adversely affect our revenues and results of operations. In particular, the municipality of São Paulo is currently serviced based on a short-term temporary contract which will end on June 1, 2019. The loss of business from the São Paulo contract will have a material adverse impact on us— see “Our contract with the municipality of São Paulo.”

Landfills. Revenue from services rendered derived from our Landfills segment increased by R$1.2 million, or 0.2%, from R$455.4 million in 2017 to R$456.6 million in 2018 due to (i) R$7.4 million increase in revenues related to CGR Catanduva landfill which were consolidated for almost all of the year in 2018, as it was sold in December 2018, compared to approximately 6 months of consolidated revenues in 2017, and (ii) aone-time volume increase in class I waste treatment for the disposal of asbestos, which increased revenue from services rendered by R$4.6 million in 2018 and (iii) other smaller transactions inbio-remediation and medical waste treatment amounting R$3.2 million, in 2018. This increase was partially offset by (i) a volume reduction at Itapevi corresponding to a R$9.0 million reduction in revenue from services rendered, reflecting a strategic decision to slow down the volume received at this site to extend the remaining capacity until expansion projects are completed, and (ii) R$4.4 million revenues decrease in Tremembé landfill manly due to a decrease of volume of Renova customer, as a consequence of the loss of Renova’s contract with CBA.

Oil & Gas. Revenue from services rendered derived from our Oil & Gas segment decreased by R$13.1 million, or 50.5%, from R$25.9 million in 2017 to R$12.8 million in 2018, due to a corresponding decrease in the volume of services rendered to our main customer in this segment, as a result of our inability to participate in certain bid processes to renew contracts and the classification of the Company as a Compliance High Risk Supplier by Petrobras.

Value Recovery. Revenue from services rendered derived from our Value Recovery segment decreased by R$6.4 million, or 17.0%, from R$37.7 million in 2017 to R$31.3 million in 2018, primarily due toone-time volume in 2017 from Dow Chemicals and Rohm & Haas clients at Sorocabaco-processing operation with no corresponding revenue stream in 2018.

Year Ended December 31, 2017 Compared to the Year Ended December 31, 2016

Revenue from services rendered decreased by R$34.2 million, or 2.5%, from R$1,380.0 million in 2016 to R$1,345.8 million in 2017. This decrease was primarily due to a R$37.0 million decrease in revenues from our Oil & Gas business segment corresponding to the decrease in the volume of services rendered to our main customer in this segment, partially offset by a R$6.8 million increase in revenues in our Collection & Cleaning Services segment mainly as a result of both inflation-driven price increases and increased momentum from our C&I business.

The table set forth below presents a breakdown of our revenue from services rendered by business segment for the periods indicated:


	For The Year Ended December 31,
	2017 (restated)			2016 (restated)

Collection & Cleaning Services. Revenue from services rendered derived from our Collection & Cleaning Services segment increased by R$6.8 million, or 0.7%, from R$922.0 million in 2016 to R$928.8 million in 2017. Of our total revenue from services rendered in our Collection & Cleaning Services segment (i) during 2017, R$830.8 million, or 89.5%, was attributable to our public collections business with municipal customers, while R$98.0 million, or 10.5%, was attributable to our C&I collections business, and (ii) during 2016, R$843.1 million, or 91.4%, of our total revenue from services rendered was attributable to our public collections business with municipal customers and R$78.9 million, or 8.6%, was attributable to our C&I collections business.

This increase in revenue from services derived from our Collection & Cleaning Services segment was primarily due to (i) a R$24.0 million increase in revenues from our São Paulo urban cleaning contract through Soma due to the positive impact of inflation-linked contractually stipulated price adjustments together with the 100% consolidation of Soma’s results starting in October 2017 following the corporate reorganization of Soma as a special purpose vehicle, whereas as previously, we only consolidated 82.0% of Soma’s results reflecting our participation in the joint operation with Corpus and (ii) a R$19.0 million, increase in revenues from our C&I collection business reflecting new relevant customers in our clients base.

These effects were partially offset by (i) a R$23.1 million, decrease in revenues from São José dos Campos collection contract due to the termination of the contract in February 2017, and (ii) a R$7.5 million, decrease from Aracaju our collection contract due to the partial termination since May 2017.

Landfills. Revenue from services rendered derived from our Landfills segment increased by R$5.6 million, or 1.2%, from R$449.8 million in 2016 to R$455.4 million in 2017 primarily due to (i) a R$32.2 million increase in revenues due to an increase in the volume disposed coupled with contractually stipulated inflation-driven price increases, particularly in relation to our Tremembé, Piratininga and Curitiba landfills and (ii) a R$5.7 million increase due to the consolidation of the results of CGR Catanduva landfill since June 2017. These effects were partially offset by a R$30.6 million, decrease in revenues from our Maceió landfill mainly due to price adjustments in 2016 resulting from the application of inflation-linked price increases covering the period from 2010 to 2014 with no corresponding revenue in 2017.

Oil & Gas. Revenue from services rendered derived from our Oil & Gas segment decreased by R$37.0 million, or 58.8%, from R$62.9 million in 2016 to R$25.9 million in 2017, due to a corresponding decrease in the volume of services rendered to our main customer in this segment, Petrobras, reflecting in part the impact of the economic and political environment on Petrobras’ operations.

Value Recovery. Revenue from services rendered derived from our Value Recovery segment increased by R$8.5 million, or 29.1%, from R$29.2 million in 2016 to R$37.7 million in 2017, primarily due to (i) R$4.9 million of carbon credit sale and (ii) a R$3.3 million, increase in revenues fromco-processing business mainly due to new customers.

Cost of Services

Year Ended December 31, 2018 Compared to Year Ended December 31, 2017

Cost of services increased by R$36.9 million, or 3.9%, from R$942.3 million in 2017 to R$979.2 million in 2018, mainly due to the following reasons:

•

an increase of R$26.2 million in labor costs manly due to the termination ornon-renewal of the Soma contract in São Paulo and our Aparecida de Goiania, Aracaju and Maceio contracts, as described below;

•

a R$10.0 million increase in fuel and maintenance costs manly due to increase in fuel price as an effect of the truckers strike in May 2018; and

•

a R$7.3 million increase in lecheate treatment costs, reflecting higher level of rain in the beginning of the year and Paulinia new cell effect (lecheate has been generated by both our closed site and the one which started its operation in February 2018). Leachate is a widely used term in the environmental sciences where it has the specific meaning of a liquid that has dissolved or entrained environmentally harmful substances that may then enter the environment. It is most commonly used in the context of land-filling of putrescible or industrial waste, and as it is commonly formed in landfills, in which case, the operator of the landfill has legal responsibility to collect and treat this substance.

The cost increase was partially offset by R$5.8 million decrease in depreciation, amortization and depletion costs due to a lower depreciation rate applied to our landfills, which is annually reviewed based on actual disposal volume and capacity.

Cost of services from our Collection & Cleaning Services segment increased by R$58.4 million, or 8.7%, from R$673.0 million in 2017 to R$731.4 million in 2018, primarily due to (i) R$28.5 million, or 6.0%, increase in direct labor and employee benefits costs related to severance payments as a result of the termination ornon-renewal of the Soma contract in São Paulo and our Aparecida de Goiania, Aracaju and Maceio contracts, (ii) R$10.6 million increase in operational costs which include maintenance, logistics and technical services, and (iii) R$5.7 million increase in fuel costs due to higher price after the truckers strike.

Landfills. Cost of services from our Landfills segment decreased by R$9.6 million, or 3.0%, from R$316.3 million in 2017 to R$306.7 million in 2018, primarily due to (i) R$9.5 million, or 15.1% decrease in depreciation, amortization and depletion costs due to a lower depreciation rate applied to our landfills, which is annually reviewed based on actual disposal volume and capacity, and (ii) R$3.5 million reduction on labor costs mainly at Paulinia and Curitiba landfills.

This decrease was partially offset by (i) R$7.1 million increase in leachate treatment and transportation caused by increased rainfall volume in the beginning of the year and (ii) R$2.4 million increase in fuel costs due to higher price after the truckers strike.

Oil & Gas. Cost of services from our Oil & Gas segment decreased by R$7.7 million, or 36.3%, from R$21.2 million in 2017 to R$13.5 million in 2018, driven by a decrease in the volume of services rendered to our main customer in this segment, Petrobras.

Value Recovery. Cost of services from our Value Recovery segment increased by R$4.7 million, or 19.2%, from R$24.4 million in 2017 to R$29.1 million in 2018, driven mainly by an increase in depreciation expenses.

Corporate. Cost of services at the corporate level decreased by R$7.0 million or 75,3%, from R$9.3 million in 2017 to R$2.3 million in 2018, due to a decrease in consulting and third party services’ fees.

Elimination and adjustments. To eliminate the effects of intercompany transactions among our business segments, we added back R$103.8 million and R$102.0 million from our total cost of services in 2018 and 2017, respectively, primarily transactions between our landfills and collection & cleaning services segments.

Year Ended December 31, 2017 Compared to Year Ended December 31, 2016

Cost of services decreased by R$61.4 million, or 6.1%, from R$1,003.7 million in 2016 to R$942.3 million in 2017, mainly due to the following reasons:

•

costs related to the lease of machinery and equipment decreased by R$29.5 million, primarily due to the substitution of certain equipment rental arrangements forlease-to-own arrangements in 2017, which are classified as capital expenditures;

•

costs related to depreciation, amortization and depletion decreased by R$24.0 million, reflecting mainly the lowering of the depreciation rate applied to our landfills, which is annually reviewed as function of disposal volume, together with the closing of one cell in our Paulínia landfill, with the consequent impact of costs direct in provision for landfill closing reversals;

•

costs related to waste treatment and disposal of leachate decreased by R$12.7 million, primarily due to (i) the commencement of our leachate treatment facilities in Curitiba inmid-2016, representing significant costs savings compared to third party leachate treatment providers and (ii) the closing of one cell in Paulínia landfill; and

•

costs related to materials used in the operations of landfills decreased by R$10.3 million, primarily reflecting the costs of implementing higher safety and quality standards in 2016 without any corresponding cost in 2017.

The above decreases were partially offset by a R$18.1 million, increase in costs related to equipment maintenance as a result of intensified maintenance activities during the year, particularly in relation to the repair of trucks and tractors.

The table set forth below presents a breakdown of our cost of services by business segment for the periods indicated:

Collection & Cleaning Services. Cost of services from our Collection & Cleaning Services segment decreased by R$5.1 million, or 0.7%, from R$678.1 million in 2016 to R$673.0 million in 2017, primarily due to (i) R$15.2 million decrease related to lower fleet depreciation and amortization, (ii) R$4.7 million decrease in payroll, charges and benefits costs related to collective bargain agreements with employees. These effects were partially offset by (i) R$11.4 million, increase in costs from equipment maintenance due to an increase in maintenance activities during the year, particularly in relation to the repair of trucks and tractors and (ii) R$3.0 million increase in transportation costs.

Landfills. Cost of services from our Landfills segment decreased by R$21.0 million, or 6.2%, from R$337.3 million in 2016 to R$316.3 million in 2017, primarily due to (i) R$16.4 million, decrease in leachate disposal costs primarily due to the commencement of our leachate treatment facilities in Curitiba inmid-2016, representing significant costs savings compared to third party leachate treatment providers, together with the closing of one cell in our Paulínia landfill and overall less rainfall during the period, (ii) R$9.4 million, decrease in depreciation, amortization and depletion reflecting mainly the lowering of the depreciation rate applied to our landfills, which is annually reviewed as function of disposal volume, together with the closing of one cell in our Paulínia landfill, (iii) R$7.9 million, decrease in the lease of machinery and equipment primarily due to the substitution of rental agreements for certain equipment forlease-to-own agreements in 2017, which are classified as capital expenditures, and (iv) R$6.0 million, decrease in fuel, lubricant and transportation costs due to the improvement in the efficiency of our operations and consequently, the reduction in amount of resources used. These effects were partially offset by (i) increase on waste treatment costs of R$6.1 million, (ii) increase in payroll, charges and benefits costs by R$5.8 million and (iii) higher equipment maintenance by R$5.5 million.

Oil & Gas. Cost of services from our Oil & Gas segment decreased by R$20.4 million, or 49.0%, from R$41.6 million in 2016 to R$21.2 million in 2017, driven by a decrease in the volume of services rendered to our main customer in this segment, Petrobras.

Value Recovery. Cost of services from our Value Recovery segment increased by R$2.4 million, or 10.9% from R$22.0 million in 2016 to R$24.4 million in 2017, driven mainly by the implementation of three more turbines in our Curitiba.

Corporate. Cost of services at the corporate level increased by R$0.7 million, or 8.1%, from R$8.6 million in 2016 to R$9.3 million in 2017, primarily reflecting an increase in expenses associated with technical consulting advisors.

Elimination and adjustments. To eliminate the effects of intercompany transactions among our business segments, we added back R$102.0 million and R$83.9 million from our total cost of services in 2017 and 2016, respectively, primarily transactions between our Landfills and Collection & Cleaning Services segments.

Operating Expenses

Year Ended December 31, 2018 Compared to the Year Ended December 31, 2017

Operating expenses increased by R$606.5 million, or 205.4%, from R$295.3 million in 2017 to R$901.8 million in 2018. The change was primarily impacted by the following:

•

Other operating expenses increased by R$545.4 million, mainly due to goodwill and fixed assets impairment charges for an amount of R$547.7 million in 2018. During 2018, we were negatively affected by the worsening of market conditions and in particular, our collection business was highly impacted, including margin compression. In the recent bid process for contracts for six parcels within São Paulo, the Company was not the bidder with the lowest price for any of the six parcels and was informed that its temporary emergency contract will terminate on June 1, 2019. In addition, as a result of decrease margins, we decided to discontinue certain collection contracts with low margins, principally through not seeking renewal. The foregoing factors led to recognition of the impairment charges referred to above.

•

General and administrative expenses increased by R$70.8 million, or 27.6%, from R$256.5 million in 2017 to R$327.3 million in 2018, mainly due a R$63.7 million increase in legal advisory services and advisory services which principally reflect costs incurred in connection with our Internal Evaluation Process and, to a lesser extent, costs incurred in connection with the Transaction and costs related to becoming a publicly traded company. In addition, our general and administrative expenses increased by R$15.1 million as a result of employee severance costs.

•

Selling expenses, net, decreased from a net expense of R$6.6 million in 2017 to a net gain of R$5.3 million in 2018, mainly due to the impact of the reversal of the allowance for doubtful accounts in 2018 as a result of an improvement in the collection of overdue receivables for which a related allowance was recorded.

Year Ended December 31, 2017 Compared to the Year Ended December 31, 2016

Operating expenses increased by R$4.3 million, or 1.5%, from R$291.0 million in 2016 to R$295.3 million in 2017. The change was primarily impacted by the following:

•

General and administrative expenses increased by R$25.4 million, or 11.0%, from R$231.1 million in 2016 to R$256.5 million in 2017, mainly due to R$57.2 million increase in provisions for legal proceedings reflecting mainly provisions established in connection with our participation in Brazil’s Tax Regularization Program resulting from our settlement of disputes that we previously had not provisioned for based on management’s earlier assessment of mid low probability of loss and provisions in connection with the findings from our Internal Evaluation Process resulting from insufficient loss carry forwards, slightly offset by a decrease in our provisions for labor proceedings as a result of favorable settlements and our reassessment of the chance of loss in certain of our ongoing proceedings. This increase in provisioning was partially offset by (i) R$11.6 million, or 9.9%, decrease in payroll charges and benefits reflecting, among other factors, a decrease in expenses related to our restructuring incentive plan, (ii) R$10.2 million, or 26.0%, decrease in advisory and legal advisory services and (iii) R$4.5 million, or 14.3% decrease in depreciation and amortization fees.

•

Selling expenses varied from income of R$10.5 million in 2016 to an expense of R$6.6 million in 2017, mainly due to the R$10.7 million increase in the allowance for doubtful accounts from our Collection & Cleaning Services segment in 2017 coupled with the impact of a reversal in the allowance for doubtful accounts in 2016 resulting from an increase in collection of overdue receivables, with no corresponding positive impact in 2017.

•

Share of profit of an associate varied from income of R$10.2 million in 2016 to an expense of R$1.0 million in 2017 reflecting the reclassification of the companies that will bespun-off in connection with the Transaction as discontinued operations (Loga, Attend and Terrestre).

The above increases were further offset by a decrease in other operating (expenses) income, net of R$46.8 million, or 61.6%, from R$77.9 million in 2016 to R$31.1 million in 2017, mainly due to (i) the R$25.6 million decrease in other operating expenses, from R$25.8 million in 2016 to R$0.2 million in 2017, reflecting mainly income in 2017 from our receipt of insurance payments that we received from our insurance providers following operational disruptions at certain of our facilities, partially offset by provisions recorded in relation to findings from the Internal Evaluation Process, from R$8.7 million in 2016 to R$10.9 million in 2017 and (ii) the R$20.9 million negative impact in connection with ourwrite-off of the call option to acquire CDR Pedreira in 2016 with no corresponding impact in 2017 (see “Item 4.A. Information on the Company—History and Development of the Company—Recent Divestments and Acquisitions—Sale of CDR Pedreira—Centro de Disposicâo de Resíduos”).

Finance Income and Expenses, Net

Year Ended December 31, 2018 Compared to the Year Ended December 31, 2017

•

Financial expenses decreased by R$280.5 million, or 52.7%, from R$532.2 million in 2017 to R$251.7 million in 2018, mainly due to (i) a decrease in interest for late payment of taxes in the amount of R$161.9 million and (ii) a decrease in interest of loans/debentures expenses of R$90.7 million as a result of a decrease in the interest rate applied to our Debt Instruments upon the completion of the Transaction.

•

Financial income increased by R$8.0 million, or 7.4%, from R$108.3 million in 2017 to R$116.3 million in 2018, due to the reversal of interest for late payment of taxes of R$69.7 million related to PERT consolidation process, and an increase in interest income of R$22.7 million. Our financial income in 2018 was lower than 2017 as a result of the recognition a discount related to the Debt Instruments upon the completion of the Transaction in the amount of R$91.5 million that we recognized in 2017.

•

Our finance income and expenses are mainly allocated to our corporate segment and are not allocated to any of our other business segments.

Year Ended December 31, 2017 Compared to the Year Ended December 31, 2016

Finance income and expenses, net, increased by R$78.4 million, or 22.7%, from R$345.5 million in 2016 to R$423.9 million in 2017. The change was primarily impacted by the following:

•

Finance expenses increased by R$135.1 million, or 34.0%, mainly due to a R$139.2 million increase in interest for late payment of taxes reflecting mainly the increase in interest expenses accrued on the balance of taxes settled by us under the Brazilian Tax Regularization Program (see ‘‘—Key Factors Affecting Our Results of Operations—Participation in Tax Regularization Plan’’ above), partially offset by a R$32.3 million, or 12.5%, decrease in interest of loans and debentures due to the renegotiation of the interest paid on our debentures in connection with the Debt Restructuring.

•

Finance income increased by R$56.6 million, or 109.5%, primarily reflecting a R$91.5 gain as a result of the discounts we obtained when renegotiating our debentures as part of the Debt Restructuring, partially offset by a R$20.0 million decrease in interest of taxes credit due to inflation adjustments related to income and social contribution tax and withheld INSS.

The significant majority of our finance income and costs is incurred at a corporate level on a company-wide basis and is not allocated to any of our business segments.

Loss Before Income and Social Contribution

As a result of the factors described above, our loss before income and social contribution (i) increased by R$440.2 million, or 139.5%, from R$315.6 million in 2017 to R$755.8 million in 2018 and (ii) increased by R$55.5 million, or 21.3%, from R$260.1 million in 2016 to R$315.6 million in 2017.

Income and Social Contribution Taxes

Under Brazilian income tax law, income taxes are paid by each entity on a stand-alone basis, as a result, changes in the consolidated effective tax rate are driven by changes in each of the entities’ effective tax rates.

In 2018, we recorded a gain of R$34.9 million in connection with income and social contribution taxes, reflecting a consolidated effective tax rate of 4.8% (gain), as compared to the nominal tax rate of 34.0%. These effects resulted mainly from a gain of R$103.9 million related to the reversal deferred tax liabilities associated to goodwill that was impaired in 2018 which was offset by unrecognized tax losses carryforwards for the year 2018 in the amount of R$90.6 million.

In 2017, we recorded a gain of R$353.5 million in connection with income and social contribution taxes, reflecting a consolidated effective tax rate of 112.0% (gain), as compared to the nominal tax rate of 34.0%. These effects resulted mainly from a gain of R$371.1 million reflecting the recognition of tax loss carryforwards (previously not recognized as a deferred tax asset) that were used in connection with our participation in the Brazilian Tax Regularization Program, which permits the settlement of tax debts with the Brazilian federal government using tax loss carryforwards (see ‘‘—Key Factors Affecting Our Results of Operations—Participation in Tax Regularization Plan’’ above).

In 2016, we recorded expenses of R$104.1 million in connection with income and social contribution taxes, reflecting a consolidated effective tax rate of 40.0% (expense), as compared to the nominal tax rate of 34.0%. In 2016, although we generated consolidated losses, a number of our subsidiaries generated taxable income resulting in the recognition of a current income tax expense of R$54.3 million. In addition, we recognized a deferred income tax loss of R$49.8 million because of the recognition of additional deferred income tax liabilities during the period. In 2016, we recorded consolidated losses before income tax and social contribution taxes of R$260.1 million, resulting in an income tax credit of R$88.4 million (using a statutory rate of 34%), however, we recognized a consolidated income tax expense (current and deferred) of R$104.1 million. The main reasons for the difference are as follows: (i) R$125.3 million of losses by subsidiary entities, for which a deferred income tax asset was not recognized on such losses as it is not expected that they will generate future taxable income, (ii) a expense of R$39.5 million innon-deductible permanent difference, (iii) a gain of R$10.9 million in amortization of taxable goodwill, (iv) a gain of R$19.9 million in deferred taxes on revenues from governmental entities, which are only taxable when paid, and (v) a expense of R$63.7 million in deferred tax assets not recognized in entities that are not expected to generate future taxable income.

Net Income/Loss for the Period From Continuing Operations

As a result of the factors described above, our profit (loss) for the period from continuing operations (i) varied by R$758.8 million, from a profit of R$37.9 million in 2017 to a loss of R$720.9 million in 2018 and (ii) varied by R$402.1 million, from a loss of R$364.2 million in 2016 to an income of R$37.9 million in 2017.

Net Income/Loss After Income and Social Contribution Tax From Discontinued Operations

We recorded a gain of R$30.5 million in 2018, compared to a gain of R$14.3 million in 2017, which represents a variance of R$16.1 million, reflecting mainly a gain from the sale of Dona Juana operations in 2018 by R$35.8 million, while in 2017, we recorded a gain of R$7.3 million in respect of transfer of our equity interests in Loga, Attend and Terrestre to Latte.

We recorded a gain after income and social contribution tax from discontinued operations of R$14.3 million in 2017 reflecting the results of operations of our Colombia-based landfill Doña Juana, which we lost control of in January 2016 and of Attend Ambiental, Terrestre and Loga that were transferred to Latte Saneamento e Participações S.A. and classified as discontinued operations.

We recorded a gain after income and social contribution tax from discontinued operations of R$3.3 million in 2016.

Net Income/Loss for the Period

As a result of the factors described above, our loss for the period: (i) varied by R$742.8 million, from an income of R$52.3 million in 2017 to a loss of R$690.5 million in 2018 and (ii) varied by R$413.2 million, from a loss of R$360.9 million in 2016 to an income of R$52.3 million in 2017.

B. Liquidityand Capital Resources

Sources and Uses

Our primary sources of cash have historically been cash flows from operations, bank borrowings and the proceeds from debt offerings. As of December 31, 2018, we had a deficiency in our working capital (calculated as total current assets minus total current liabilities) of R$1,289.8 million and a capital deficiency of R$1,149.2 million, and as of December 31, 2017, we had a working capital of R$293.4 million and a capital deficiency of R$455.9 million. For further information, see Note 3 to our audited consolidated financial statements included elsewhere in this annual report.

As a result of liquidity constraints emanating in part from material contract losses and reductions in our Collection & Cleaning Services business segment, we have not been able to comply with the financial covenants included in our Debt Instruments for and as of the year ended on December 31, 2018, and we are currently in breach of such covenants. In addition, we have not yet made any payments to Angra due to our liquidity constraints and, accordingly, Angra can exercise remedies against us. Furthermore, management has identified several significant obligations arising during 2019 that require funding through liquidity, primarily relating to (i) the payments we are required to make for severance and other demobilization costs related to discontinued operations (for example, the contract with the municipality of São Paulo for cleaning services, which will terminate on June 1, 2019) and (ii) capital expenditures (e.g., new trucks and equipment) required in connection with contract renewals, such as the investment obligations arising under the contract with the municipality of Curitiba for cleaning services, which was renewed on January 3, 2019 for an additional five year period (see “Item 3. Key Information—D. Risk Factors—A significant portion of our revenue is derived from a small number of customers, and partial or full loss of revenues from any such customer may adversely affect our revenues and results of operations. In particular, the municipality of São Paulo is currently serviced based on a short-term temporary contract which will terminate on June 1, 2019. The loss of business from the São Paulo contract will have a material adverse impact on us—Our contract with the municipality of São Paulo.” and “Item 3. Key Information—D. Risk Factors—A significant portion of our revenue is derived from a small number of customers, and partial or full loss of revenues from any such customer may adversely affect our revenues and results of operations. In particular, the municipality of São Paulo is currently serviced based on a short-term temporary contract which will terminate on June 1, 2019. The loss of business from the São Paulo contract will have a material adverse impact on us—Our contract with the municipality of Curitiba.” above).

100

We do not anticipate that cash flows from operations will be sufficient to provide us with sufficient financial resources to cover our obligations or that financing will be available to us on reasonable terms, if at all and as a result of such circumstances, the Company has engaged an outside restructuring advisor as well as outside legal counsel to advise in connection with the debt restructuring process. The Company expects to conclude the debt restructuring process during 2019, but there can be no assurance that the debt restructuring process will be successful or that the Company will be able to generate sufficient liquidity in order to fully address the liquidity concerns.

Cash Flows

The following table sets forth for the periods indicated a summary of our cash flows:


	For The Year Ended December 31
	2018			2017			2016
	(in R$ millions)
Cash flow provided by operating activities		21.0			243.3			213.5
Net cash used in investing activities		(86.9	)		(200.3	)		(166.7	)
Net cash provided by (used in) financing activities		1.7			10.6			(63.5	)
(Decrease) increase in cash and cash equivalents		(64.2	)		53.6			(16.7	)

Cash Flows Provided by Operating Activities

We generated R$21.0 million of net cash from operating activities in 2018, compared with R$243.3 million in 2017, representing a R$222.3 million, or 91.4%, decrease. This decrease in operating cash flows was primarily due to a loss of R$690.5 million in 2018, compared to a profit of R$52.3 million in 2017. The variance from 2017 to 2018 primarily reflects the following impacts that occurred in 2018: (i) an increase in recognition of goodwill and fixed assets impairments of R$510.5 million, from R$37.2 million in 2017 to R$547.7 million in 2018, (ii) lower impact from current and deferred income taxes by R$294.6 million, from R$371.1 million in 2017 to R$76.5 million in 2018, (iii) lower accrual of monetary variation, financial charges and interest by R$264.0 million, from R$380.2 million in 2017 to R$116.2 million in 2018, (iv) other individually immaterial variations which considered as a whole produces a variation of R$20.6 million.

We generated R$243.3 million of net cash from operating activities in 2017, compared with R$213.5 million in 2016, representing a R$29.8 million net increase. This increase in operating cash flows was primarily due to a net profit of R$52.3 million in 2017 compared to net losses of R$360.9 million in 2016. This effects were partially offset by (i) a R$420.9 million net decrease from deferred income and social contribution taxes reflecting mainly our participation in the Brazilian Tax Regularization Program, which corresponded to a R$373.2 million positive impact on our statement of profit or loss in 2017 due to recognition ofoff-balance tax loss carryforwards, without any corresponding positive impact on our cash flow and (ii) a R$104.3 million net increase in trade accounts receivable mainly associated with an increase in overdue payments from certain public entity customers due to political and economic environment in Brazil, from R$192.1 million in 2016 to R$87.8 million in 2017.

Cash Flows Used in Investing Activities

We used R$86.9 million of cash in investing activities in 2018, compared with R$200.3 million used in 2017, representing a R$113.4 million decrease. This decrease in cash used in investing activities was primarily due to (i) R$50.1 million decrease in cash used for the acquisition of intangible assets principally attributable to the implementation of SAP operating systems in 2017, (ii) a R$22.9 million decrease in cash used in the acquisition of property, plant and equipment in 2018, and (iii) an increase in receivables from the sale of certain of our assets in an amount of R$33.8 million.

We used R$200.3 million of cash in investing activities in 2017, compared with R$166.7 million used in 2016, representing a R$33.6 million net increase. This net increase in cash used in investing activities was primarily due to (i) a R$45.6 million net increase in cash used for the acquisition of intangible assets reflecting mainly SAP operating systems implementation, (ii) a R$41.3 million net decrease in cash generated from marketable securities resulting from our return of funds held in anearn-out escrow account relating to our historical acquisition of Viva Ambiental considering the conclusion of theearn-out period in 2016. These effects were partially offset by a R$53.6 million net decrease in payment for acquisition of subsidiaries mainly associated withearn-out payments made in 2016 relating to the acquisition of Viva Ambiental in 2012, with no corresponding payments made in 2017.

101

Cash Flows Used in Financing Activities

We generated R$1.7 million in cash from financing activities in 2018, compared with R$10.6 million of cash generated in 2017, representing a R$8.9 million net decrease. This decrease was due primarily to a R$387.3 million received as capital contribution in connection with the Transaction in 2017. This was offset by a R$81.0 million reduction in the repayment of loans and financing and debentures and a R$281.9 million reduction in the payment of interest and financial charges in 2018, as a result of the changes made by the Debt Restructuring which provided for certain grace periods for the payment of interest and principal.

We generated R$10.6 million in cash from financing activities in 2017, compared with R$63.5 million of cash used in 2016. This variation was due primarily to a R$387.3 million net increase in capital reflecting the capital contribution derived from the Transaction, partially offset by a R$289.9 million net increase in payment of interest and financial charges related to repayment of debentures in connection with the renegotiation of the debentures as part of the Debt Restructuring.

Borrowings

As of December 31, 2018, our total financial indebtedness, consisting primarily of our Debt Instruments and, to a lesser extent, other working capital and BNDES loans and financings and finance leases, was R$1,594.7 million, as compared to R$1,454.5 million and R$1,692.3 million as of December 31, 2017 and 2016, respectively. As of December 31, 2018, 97.6% of our total indebtedness was linked to floating rates compared to 98.7% and 99.1% as of December 31, 2017 and 2016, respectively.

In connection with the Transaction, on December 26, 2017, we repaid US$110.6 million under our existing debentures and related debt acknowledgment instrument to the Creditors. In addition, the debenture holders granted us a reduction corresponding to 25% of the prepaid amount. We then amended and restated the terms of our existing debentures and related debt acknowledgment instrument. For additional information, see “—A. Operating Results—Key Factors Affecting Our Results of Operations—Restructuring Plan” above and “—Debt Restructuring and Refinanced Debt” below.

Debentures

As of December 31, 2018, the substantial majority of our indebtedness consisted of amounts due under two separate issuances of debentures in 2011 and 2012, respectively, which have been restructured in connection with the Transaction.

First issuance of debentures: on June 27, 2011, we issued debentures in a principal outstanding amount of R$680.0 million exclusively to BTG Pactual, then one of our controlling shareholders. On June 13, 2017, we, Estre Coleta Holding S.A. and BTG Pactual executed a Private Debt Acknowledgment Instrument (Instrumento Particular de Confissão de Dívida) that progressively repealed and replaced the indenture governing our first issuance of debentures, and had substantially the same terms and conditions as those debentures. At the closing of the Transaction, we completed our Debt Restructuring, pursuant to which we partially paid down the outstanding balance of these debentures and related debt acknowledgment instrument, then amended and restated the terms of these debentures and related debt acknowledgment instrument in the total principal amount of their remaining outstanding balance.

Second issuance of debentures: on December 14, 2012, we completed a second issuance of debentures in a principal outstanding amount of R$650.0 million. At the closing of the Transaction, we completed our Debt Restructuring, pursuant to which we partially paid down the outstanding balance of these debentures, then amended and restated the terms of these debentures in the total principal amount of their remaining outstanding balance.

The reduction of our outstanding balance under our first issuance of debentures as of December 31, 2018 as compared to December 31, 2017 reflects mainly our execution of a Private Debt Acknowledgment Instrument (Instrumento Particular de Confissão de Dívida) in connection with the Transaction that progressively repeals and replaces the indenture governing our first issuance of debentures and has substantially the same terms and conditions as those debentures. Accordingly, amounts due under our first issuance of debentures will incrementally decrease over time, with a corresponding increase in amounts due under the Private Debt Acknowledgment Instrument (which we classify as a working capital loan). Therefore, such reduction does not represent a decrease of our total indebtedness but rather a reallocation of amounts due under different debt instruments.

Debt Restructuring and Refinanced Debt

On August 10, 2017, we entered into a binding facility commitment letter with the Creditors, the holders of our debentures and related debt acknowledgment instrument, which provided for the restructuring of our existing debentures and related debt acknowledgment instrument through the prepayment of US$200 million, a partial debt write-down and the restructuring of the existing debentures, in connection with and conditioned upon the Transaction. On December 7, 2017, we amended the binding facility commitment letter, pursuant to which the Creditors agreed to amend the required prepayment in connection with the Transaction to a defined range of the repayment of a minimum debt prepayment of US$100 million and a maximum debt prepayment of US$200 million.

At the closing of the Transaction, we completed our Debt Restructuring, pursuant to which we used an amount of US$110.6 million from the total cash investments received by us to partially prepay certain of our existing debentures and related debt acknowledgment instrument, each denominated in Brazilian reais, proportionally to the stake each of our Creditors held in the debt represented by the Debentures on the closing date of the Transaction. Upon receipt of such payment, the Creditors granted us a reduction corresponding to 25% of the prepaid amount.

We then amended and restated the terms of our existing debentures and related debt acknowledgment instrument after the payment of the amount of US$110.6 million. In addition, the debenture holders granted us a reduction corresponding to 25% of the prepaid amount. The Creditors continue to hold the Refinanced Debt in the following proportion: 54.4% to Banco BTG Pactual S.A., 22.8% to Santander and 22.8% to Itaú Unibanco S.A.

The total amount outstanding under the Refinanced Debt as of December 31, 2018 was R$1,548.3 million (R$1,426.8 million as of December 31, 2017). The Refinanced Debt bears interest at a rate of CDI plus 2.0% per annum, with payments of principal to be repaid semi-annually in 11 installments after a three-year grace period (expiring in December 2020) and maturing eight years after the disbursement date of the Refinanced Debt (being December 20, 2025). Interest payments under the Refinanced Debt will be made semi-annually after a grace period on the cash payment of interest of two years (expiring in December 2019) and the interest accrued in the first 18 months from December 2017 will be capitalized and incorporated into the principal of the Refinanced Debt.

A significant part of our assets have been pledged as collateral to secure repayment of the Refinanced Debt part of its, and of its material controlled subsidiaries, assets, which prevented us from granting guarantees to third parties without obtaining Creditors’ waivers. The Refinanced Debt is secured by collateral consisting of (i) a lien on all real estate relating to the operational landfills; (ii) a lien on all material subsidiaries controlled, directly or indirectly, by us; (iii) a fiduciary assignment of the remaining balance originated from the foreclosure of liens described in this paragraph; and (iv) corporate guarantees of all material subsidiaries controlled, directly or indirectly, by us. The debt admission instrument related to our first issuance of debentures is also secured by a fiduciary assignment of certain real estate assets owned by us. In addition, the Refinanced Debt is secured by a fiduciary lien on all (except for 4.38% secured for the benefit of Angra) of the Company’s common shares as security for the payment of all obligations related to the Refinanced Debt.

103

The Refinanced Debt contains affirmative and negative covenants customary for facilities of this nature, including, but not limited to, financial covenants (such as net debt to EBITDA ratio and debt service coverage ratio) and negative pledges covenants limiting our ability to pledge our assets as collateral. In particular, the instruments governing our Refinanced Debt require us to maintain the following financial ratios, which must be measured semi-annually as of June 30 and December 31 of each year, on a Company consolidated basis, starting on December 31, 2018:

•

As of December 31, 2018, the Company’s consolidated annual net debt to EBITDA ratio must be 4.0x or less;

•

As of December 31, 2019 and subsequent fiscal year-ends, the Company’s consolidated annual net debt to EBITDA ratio must be 3.5x or less;

•

For three consecutive semi-annual periods starting in 2019 and thereafter, the Company’s consolidated net debt to EBITDA ratio must be 3.0x or less;

•

If the Company’s net debt to EBITDA ratio is above 2.8x as of any measurement date, then our debt service coverage ratio must be at least 1.2x; and

•

If the Company’s consolidated net debt to EBITDA ratio is 2.8x or less as of any measurement date, then the Company’s consolidated debt service coverage ratio must be at least 1.0x.

For purposes of our Refinanced Debt, net debt is calculated as the Company’s consolidated loans and financing and debentures, accounts payable for periods greater than 60 days related to asset acquisitions, other accounts payable (including tax installment accounts but excluding trade accounts payable), indebtedness with related parties, derivatives, finance leases and personal guarantees or other credit exposures, less cash and cash equivalents and financial investments. EBITDA is calculated as the Company’s consolidated net income plus taxes, finance income, net finance cost, and depreciation, amortization and depletion, for the trailing twelve months. Debt service coverage ratio is a measure of the Company’s cash flow available to pay our current debt obligations, calculated in accordance with a formula stated in the instruments governing our Refinanced Debt. The Refinanced Debt also contain events of default customary for facilities of this nature.

The Company’s consolidated net debt to EBITDA ratio as of December 31, 2018 was 7.9x, higher than the 4.0x required by the relevant covenant. In addition, the Company’s debt service coverage ratio as of December 31, 2018 was of negative 15.6x, lower than the 1.2x ratio required by the relevant covenant. The breach of financial covenants referred to above was a result of the Company’s lower than expected operating results for the year ended December 31, 2018. Competition for public collection contracts was extreme during the course of 2018, resulting in price discounts and significant margin compression, including material reductions in relation to our Sao Paulo urban cleaning contract. For additional information, see “Item 3. Key Information—D. Risk Factors—A significant portion of our revenue is derived from a small number of customers, and partial or full loss of revenues from any such customer may adversely affect our revenues and results of operations. In particular, the municipality of São Paulo is currently serviced based on a short-term temporary contract which will terminate on June 1, 2019. The loss of business from the São Paulo contract will have a material adverse impact on us—Our contract with the municipality of São Paulo.”

In addition, the terms of the Debt Instruments required that, by December 31, 2018 the Company completed registration of certain liens on certain real estate relating to operational landfills with the appropriate governmental agencies and to provide certain documents listed in the annexes to the debentures. The Company was unable to comply with such covenants by December 31, 2018.

Therefore, as a result of the breach of the consolidated net debt to EBITDA ratio and the debt service coverage ratio, the failure to register the relevant liens and to provide certain of the documents required to be provided, the Company is in default of its obligations under the Debt Instruments. These defaults entitle the banks that hold the Debt Instruments to accelerate the debt obligations and declare that all amounts owing under the Debt Instruments are immediately due and payable.

Working Capital Loans

Working capital loans represent a significant portion of our indebtedness due to our recent private debt acknowledgment instrument (related to debentures) executed with BTG Pactual in connection with the Debt Restructuring that progressively repeals and replaces the indenture governing our first issuance of debentures and had substantially the same terms and conditions as those debentures. (see “Borrowings” above). As of December 31, 2018, the total outstanding balance of our indebtedness classified as working capital loans was R$581.9 million.

Financing Agreements with BNDES

We historically were able to secure attractive financing for the acquisition of a significant portion of our fleet of heavy equipment and machinery, including our collection and transfer trucks, as well as for certain other investments in infrastructure such as the development of new landfills through loans from the FINAME program administered by BNDES on terms that were generally more favorable than those offered by commercial banks in Brazil.

As of December 31, 2018, we were party to 15 financing contracts funded by BNDES under its FINAME program. These contracts have an average term of 60 months and a standard grace period of six months for the payment of principal. Following the applicable grace period, payments are due monthly. The loans under our FINAME financings bear interest at rates indexed to TJLP, plus a spread ranging from 2.5 to 9.0 per annum. The assets purchased with proceeds of the financing secure our obligations under the contracts, which are also guaranteed by promissory notes or by our controlling shareholders. As of December 31, 2018, the total outstanding balance of our FINAME financings was R$0.3 million.

As a result of deteriorating macroeconomic conditions in Brazil and the Brazilian government’s consequent struggle to rebalance its public accounts amid an escalating political and economic crisis, the FINAME program was subject to material adjustments starting in 2014 pursuant to which the overall funding available under the programs was reduced and the interest rates available through the programs were increased. As a result, we can no longer rely on BNDES funding to support the acquisition of new heavy equipment and machinery and the attractive interest rates offered through such financing. Accordingly, we must seek other sources of funding for acquisition of equipment, including leasing arrangements.

D. Trend Information

The Brazilian waste management industry is highly fragmented, and there are several prominent players that engage in all aspects of the value chain, including collection, recycling, and landfill disposal. In terms of the collection of waste, no single player accounts for more than 11.0% of market share, and the top five largest players collectively accounted for 31.6% in 2017, of which we held a leading 10.4% market share. Comparatively, the top three largest U.S. solid waste management businesses have grown market share to approximately 40% of the total U.S. market, according to IBIS data. Competition in the waste management industry outside the top five large players is characterized by small regional and privately owned solid waste companies, which generally maintain collection operations with limited or noin-house transfer, recycling or landfill disposal capabilities. Estre also competes with municipalities that maintain waste collection or disposal operations, which may have financial advantages due to the availability of tax revenue andtax-exempt financing, but which do not provide waste management services outside the borders of their own municipality.

Brazil generated around 78.4 million tons of MSW in 2017, representing a CAGR of 1% since 2013, according to ABRELPE data, while population growth during the same period was 1.5% according to IBGE. The majority (74.7%) of this waste originated from two main regions in Brazil: the Southeast and Northeast. In 2017, approximately R$25.8 billion was spent by municipal departments in Brazil on urban cleaning and MSW collection and disposal, according to ABRELPE data. The industry, however, remains underpenetrated, in 2017 it is estimated that approximately 7.0 million tons of waste volume generated remained uncollected according, and approximately 41.0% of the 71.5 million tons of MSW collected was improperly disposed of.

Over the past decade, economic growth in Brazil has lifted millions out of poverty and into the middle class, stimulating solid waste generation on both an absolute and per capita basis with a 1.6% and 0.1% CAGR, respectively, from 2012 to 2016, despite a 0.9% CAGR decline in GDP over the same period. While Brazil has experienced negative GDP growth starting in 2014, prior to such stagnation and eventual recession, there was a strong correlation between growth in GDP and increases in waste generation and collection. For example, in 2010, when GDP growth was 7.5%, collection growth was 8.0% year-over-year compared to generation growth of 6.9% year-over-year. Even with negative GDP growth in 2015, MSW generation and collection grew on both absolute terms and on a per capita basis. In 2016, however, MSW generation and collection followed the negative GDP growth and decreased both on absolute terms and on a per capita basis. Between 2012 and 2016, waste collection in Brazil experienced a CAGR of 1.9%, driven by improved environmental regulations. The table set forth below illustrates the growth of waste generation and waste collection between 2013 and 2017:

Waste management in Brazil benefits from two significant catalysts. First, Brazil’s positive commitment towards environmental matters and environmental regulation led to the enactment of the National Solid Waste Policy (PNRS), by the Brazilian Ministry of the Environment in 2010. Among other things, the creation of the PNRS established long sought-after sustainability goals and introduced the following measures:

•

Concept of shared responsibility among waste generators, collectors and waste management companies;

•

The creation of regional waste management authorities so that smaller municipalities can share resources to promote cost reduction programs; and

•

Tax incentives for energy generated from waste.

Most notably, the PNRS made uncontrolled disposal of waste illegal and has imposed strict penalties for the improper disposal of waste. To comply with the requirements of the PNRS, various municipalities throughout Brazil have implemented deadlines to comply with the proper disposal of solid waste, ranging from July 2018 to July 2021 depending on size of the municipality:

•

State capitals and metropolitan municipalities must comply by July 2018;

•

Cities that neighbor state capitals or metropolitan areas and those with more than 100 thousand inhabitants must comply by July 2019;

•

Cities between 50 and 100 thousand inhabitants must comply by July 2020; and

•

Cities with less than 50 thousand inhabitants must comply by July 2021.

To illustrate the untapped potential that the adoption of the PNRS has given private waste management companies, 41.0% of the 78.4 million tons of MSW collected in Brazil in 2016 (corresponding to 29.3 million tons of waste) had been improperly disposed of. The table below sets forth the waste collected in Brazil in 2017:

ABRELPE

Second, as Brazil’s GDP per capita increases, so does its generation of waste. As the chart below illustrates, Brazil had already become the third largest solid waste producer in the world by 2015, only behind China and the United States. Nevertheless, Brazil (5.1%) had a comparatively higher CAGR than the United States (0.7%) in terms of waste generation per capita between 2010 and 2015.

Solid Waste Generation in 2015

Solid Waste Association

Currently, Brazilians produce on average 379.6 kg of waste per year, while Europeans and Americans produce 470 kg and 712 kg of waste per year on a per capita basis, respectively. If Brazil’s GDP per capita continues to grow at its recent pace waste production might reach European levels before 2025, bringing an additional 40 million tons of waste into the waste management industry, or approximately 65% growth. The table below compares Brazil, the European Union and the United States in waste generation, waste generation per capita CAGR, and estimated waste generation for the periods indicated:

The solid waste industry can be classified into several asset categories including collection operations, landfills, and recycling. Vertical integration of these assets into a single network enables Estre to better manage the waste stream throughout the entire value chain driving efficiencies and superior customer service.

Collection

Waste collection involves the gathering of waste from its point of origin and the delivering of waste to a treatment facility. The collection of waste is the first link in the waste management value chain and puts waste collectors in direct contact with waste producers. Waste collectors are divided by producer type and by waste class and can either be private companies or state-owned entities. Collection services can be contracted via contract or provided by the municipality. MSW collection services in Brazil remain highly fragmented with a large number of operators across the country varying in size, scale and segment focus. Hazardous residues (Class I) collection is often performed by specialized waste management companies with the ability to properly classify and transport the waste as well as maintain required waste management records.

108

Another characteristic of the Brazilian waste management market is its regional disparity, with predictably higher amounts of waste collected in more heavily populated regions. More than half of the waste (52.9%) generated in Brazil is collected in the Southeast region, which includes large urban centers such as São Paulo, Rio de Janeiro and Belo Horizonte, while approximately 22.4% is collected in the less densely populated Northeast region. The graphic below illustrates the regional differences in waste collection in 2017:

Collection by Region in 2017

Recycling

In Brazil, the major waste collectors provide the waste stream to recycling cooperatives. These cooperatives are in charge of sorting, compacting and reselling the recyclable products. Some waste management companies such as Estre and Cavo, partner with local NGO’s to provide support and advice to these cooperatives to improve their operations. The proper incentives or marketability of the recyclable products are key for the increase in the rates of recycling. Historically, organic waste represents approximately two thirds of the country’s total Urban Solid Waste and is followed by plastics and cardboard, which account for approximately 20% to 25% of the total. The high concentration of organic materials is illustrative of the high percentage of household income spent on groceries. As the economy grows and matures, recyclable materials will increase which shall complement revenues.

The trends in recycling in Brazil are geared towards reverse manufacturing, particularly for used refrigerators and air conditioning units. This activity consists of dissembling refrigerators and air conditioning units, recycling some of the parts and capturing chlorofluorocarbons. The success of some of the reverse manufacturing initiatives is still highly dependent on new regulation and subsidies to be established in Brazil to promote the acquisition of newer, more energy efficient refrigerators. Landfills, as described below, shall be impacted by recycling requirements as it may reduce volumes. However, the value added from additional revenue from higher margin sorting, value recovery and reverse engineering businesses offsets the effects of potentially lower volumes.

Landfills

Disposal of waste in landfills is the most widely-used method to dispose of waste in Brazil. Landfills involve sophisticated lining and collection systems to control leachate, avoid contamination of the ground water, as well as capture and burn biogas. There are three types of landfills in Brazil mainly differentiated by their treatment infrastructure and facilities and the environmental standards used:

•

Sanitary Landfills orAterro Sanitários: Brazil’s highest possible landfill classification, awarded to landfills with the necessary infrastructure to meet environmental and public safety requirements. In 2017, 59% of MSW was disposed of in Sanitary Landfills.

109

•

Controlled Landfills orAterro Controlado: This category applies to landfills that have some treatment infrastructure in place but are not fully compliant with applicable environmental and public safety requirements. In 2017, 23% of MSW was disposed of in Controlled Landfills.

•

Uncontrolled Landfills orLixão: This category applies to the lowest disposal classification in Brazil and represents a location where waste is thrown with no established treatment infrastructure (e.g., no drainage). In 2017, 18% of MSW was disposed of in Uncontrolled Landfills.

We believe that Brazil will continue to expand on existing landfills and to establish new landfills in the future, which is similar to the trend seen in the United States market. Landfills are seen as a stable source of revenue with tipping fees growing faster than inflation, and having waste to energy and recycling as complementary revenues. However, the lengthy permitting process and significant capital costs of landfill development serves as a key barrier to entry. Since 1982, tipping fees in the United States have been growing faster than inflation. The U.S. Consumer Price Index (CPI) increased 2.9% since 1982, while tipping fees grew 6.0%, or a 3.1% CAGR in real terms. In the United States, tipping fees average US$50 per ton while in Brazil, they range from US$15 to US$30 per ton, depending on the landfill site and region. Drivers of the sharp growth in tipping fees are (i) growth in waste generation per capita; (ii) the need for bigger and further away landfill projects; (iii) increasing complexity in permitting higher disposal and treatment costs; and (iv) the development of recycling alternatives and otherwaste-to-energy initiatives. As illustrated by the graphs below, the vast majority of municipalities in Brazil do not yet have designated landfills and there is ample room for growth:

LOGO

Source: ABRELPE

There are significant opportunities in the waste disposal segment, notably in the less-densely populated Northern, Northeastern and Center-Western regions of Brazil. To accomplish the goal established by the Brazilian Ministry of the Environment, it is necessary to more than double the number of municipalities that dispose of MSW in landfills. Several large municipalities, most notably Rio de Janeiro, the second largest city in Brazil with a metropolitan population of over 12 million people, have yet to follow the national trend of granting private MSW collection concessions as has already been done in other cities such as São Paulo, Maceió and Salvador. According to ABRELPE, in 2017, approximately R$25.8 billion (equivalent to US$6.5 billion) was spent in Brazil on urban cleaning and MSW collection and disposal. The vast size of the urban cleaning, collection and disposal market, coupled with the low penetration rate of private services, illustrates the tremendous growth potential of this market segment.

Medical Waste

In recent years, there has been strong growth in Brazil in the medical waste collection segment, with additional room for positive growth in the future. In 2017, 81% of the country’s municipalities had implemented a medical waste treatment system. According to ABRELPE, 256.9 thousand tons of medical waste were properly collected and disposed of in Brazil in 2017, representing a 1.1% CAGR since 2012. Federal, state and municipal regulators continue to pass regulation to enforce proper collection, treatment and final destination of medical waste. The heavily populated Southeast region represented 70.3% of the medical waste collected in 2017 while the Northeast region represented an additional 14.4%. The North, South and Center-Western regions represented the remaining 15.2%. In 2017, medical waste treatment technologies in Brazil had an installed capacity of 1,007 tons per day.

ITEM 6.

DIRECTORS, SENIOR MANAGEMENT AND EMPLOYEES

A. Directors and Senior Management

Our board of directors is a decision-making body responsible for formulating and monitoring the implementation of the general guidelines and policies for our business, including our long-term strategies. Our board of directors is responsible, among other things, for appointing and supervising our executive officers and appointing our independent auditors.

111

Our board of directors is currently comprised of six directors. At least a majority of our directors qualify as independent directors under the rules promulgated by NASDAQ. During the course of 2018, four of our directors resigned, as noted below.

Our Memorandum and Articles provides for a board of directors that is divided into three classes, each of which serves for a staggered term of three years. At each annual meeting of shareholders, a class of directors is elected for a three-year term to succeed the same class whose term is then expiring. Our board of directors is currently divided into the following classes:

•

Class I: Gesner Oliveira, Fabio Pinheiro and Ricardo Pelucio;

•

Class II: Klaus Pohle; and

•

Class III: Sergio Pedreiro and Stephen Trevor.

Our Memorandum and Articles provide that the number of directors, who will be no less than one member, may be increased or decreased from time to time by a resolution of the board of directors. Each director’s term continues until the election and qualification of his successor, or his earlier death, resignation, or removal. Directors are assigned to each class in accordance with a resolution or resolutions adopted by the board of directors. When the number of directors is increased or decreased, the board of directors will determine the class or classes to which the increased or decreased number of directors will be apportioned.

2017 Omnibus Plan

Generally. On December 21, 2017, our existing shareholder adopted the 2017 Omnibus Equity Incentive Plan, or 2017 Plan, which will provide for the issuance of share options, share appreciation rights, restricted shares, restricted share units, and other share-based and cash-based awards. Options granted under the 2017 Plan may be an incentive stock option (or ISO, as described in Section 422 of the Code) or an option that does not qualify as an ISO (or Nonstatutory Option). Each option agreement must specify whether the Option is an ISO or a Nonstatutory Option. The purposes of the 2017 Plan are to provide an additional incentive to certain of our employees, directors, independent contractors and consultants whose contributions are essential to the growth and success of our business, in order to strengthen the commitment of such persons to us, motivate such persons to faithfully and diligently perform their responsibilities and attract and retain competent and dedicated persons whose efforts we expect will result in our long-term growth and profitability.

However, only our employees are eligible to receive grants of ISOs.

Furthermore, no participant who is anon-employee member of our board of directors shall be granted awards in any consecutive12-month period in respect of ordinary shares having a fair market value of more than US$500,000.

Authorized Shares Under the Plan. The 2017 Plan is currently limited to the issuance of 576,337 ordinary shares. Any amount available for issuance under the 2017 Plan may be issued pursuant to the exercise of ISOs.

Code of Ethics and Anti-Corruption Policy

In 2015, under the leadership and guidance of our new CEO, Mr. Sergio Pedreiro, and in response to Brazil’s new anticorruption law adopted in 2014 and an intensified focus in Brazil on the prevention of corrupt practices, we implemented a new compliance program applicable to all employees and suppliers of the Company that is focused on transparency and ethical conduct. Since 2015, we have invested significantly in our internal controls mechanisms with the objective of auditing, detecting and reporting irregularities, imposing disciplinary measures and taking remedial or punitive measures in the case of violations. We have a focused commitment to continuing to strengthen our compliance policies and internal control systems across our organization, including all our subsidiaries and affiliates.

As part of our new compliance infrastructure, in 2015, we hired a senior level Compliance Officer to spearhead the redesign of our compliance program. Under the direction of the Compliance Officer, we developed several committees and mechanisms designed to detect and prevent improper conduct, including the establishment of a Risk Management and Compliance division to implement and enforce our compliance program, with the goal of aligning such program with the best practices and requirements of the Brazilian Anti-Corruption Law.

In addition, we implemented a Code of Ethics and an Anti-Corruption Policy that establishes guidelines and responsibilities for various stakeholders in an effort to ensure compliance with the Brazilian Anticorruption Law and our own ethical standards. These policies, among other features, impose due diligence requirements for the engagement of suppliers, business with government customers, new business, the hiring of new executives and merger and acquisition processes. In addition, the policies stipulate stringent guidelines regarding sponsorship and donations. We are also required to include our anticorruption policies in agreements with suppliers, partners and intermediary agents, as well as to obtain representations from such parties as to their adherence with our compliance policies. We now also regularly provideon-site compliance training to employees and business partners, and require regular due diligence and internal testing and review of these policies.

As part of our new compliance policies, bonus payments and profit sharing plans are now linked to adherence to our compliance procedures, which we believe is an integral part of our compensation structure. In addition, we have also established an internal whistleblower hotline and have sponsored company-wide participation in the annual Estre Compliance Day.

In addition, in connection with the consummation of the Transaction, we have adopted additional compliance policies at the Registrant-level designed to ensure our compliance with international governance and compliance standards on, among other things, anticorruption, insider trading, related party transactions and disclosure standards, such as the Foreign Corrupt Practices Act and the NASDAQ corporate governance and compliance rules.

We also offer our employees training and career development planning.

Our management model is based on meritocracy, with multi-year projects coupled with short-term goals and a compensation policy adopting below-market fixed salaries with above-market variable compensation goals, which we believe closely aligns shareholders’ and management’s interests.

Outsourced Services

We have outsourced certain activities that support our four business segments, including ancillary activities that are not directly related to our core business segments, such as cleaning, landfill security and certain legal services.

Unions and Labor Relations

Our employees are represented by local labor unions in the cities and states in which we operate, namely: Femaco (Federação dos Trabalhadores em Serviços, Asseio e Conservação Ambiental, Urbana e Áreas Verdes no Estado de São Paulo) and Femaco’s state-based equivalent union, Siemaco (Sindicato dos Trabalhadores em Empresas de Prestação de Serviços de Asseio e Conservação e Limpeza Urbana), among others. We believe we have good working relationships with the main unions that represent our employees. We have entered into collective bargaining agreements with the relevant labor unions and annually renegotiate such agreements. We believe we are in material compliance with the terms of each collective bargaining agreement we have entered into. However, in the event of a disagreement, we seek legal means in order to defend our interest and position.

123

Share Put Option Agreement

On March 6, 2018, Angra confirmed the exercise of its put option to sell all of its shares to the Company, and we are required to pay the exercise price of approximately R$40.3 million by September 6, 2018.

See “Item 10.C. Additional Information—Material Contracts—Share Put Option Agreement.”

We have not yet made any payments to Angra due to liquidity constraints, which constitutes a default under the Share Put Option Agreement entered into with Angra. The Company is in ongoing negotiations with Angra regarding the terms for the payment of amounts owed to them and there are no assurances that we will be successful in these negotiations, and Angra has reserved all other rights, remedies, actions and powers to which it may be entitled. As a result, Angra may seek certain remedies afforded to them under the Share Put Option Agreement and otherwise under Brazilian law, including the enforcement of their security interest of 4.38% of the share capital of the Estre Ambiental S.A. For these reasons, the Company believes that it may be required to also include this debt as part of the debt restructuring efforts. See “Item 3.D. Key Information—Risk Factors—Risks Related to Our Business—As of December 31, 2018 we recorded significant negative working capital and capital deficiency, we are currently in breach of certain financial covenants and contractual obligations, and our ability to avoid a judicial reorganization is dependent on our ability to successfully complete a debt restructuring and significantly improve our liquidity position.”

Legal and Administrative Proceedings and Investigations

Overview

We are party to various judicial and administrative proceedings, including tax, labor, regulatory, environmental and civil proceedings. As of December 31, 2018 and December 31, 2017, our provisions for legal proceedings were R$70.3 million and R$147.8 million, respectively. Of the total provisions, R$36.3 million and R$25.0 million as of December 31, 2018 and December 31, 2017, respectively, related to ongoing civil and labor legal and administrative proceedings that based upon the advice of our external counsel, we estimate as having a probable likelihood of loss, and R$34.0 million and R$122.7 million as of December 31, 2018 and December 31, 2017, respectively, related to tax proceedings. The reason for the reduction in our tax provisions as of December 31, 2018 arises out of our adhesion to Tax Regularization Programs, as further detailed below, which was partially offset by additional tax provisioning resulting from the findings of the Internal Evaluation Process. For more information, see “Item 5.A. Operating and Financial Review and Prospects—Operating Results—Key Factors Affecting Our Results of Operations—Participation in Tax Regularization Plan.” In addition, judicial deposits totaled R$12.0 million and R$9.9 million as of December 31, 2018 and December 31, 2017, respectively.

In recent years, Brazil has intensified its focus on the prevention of corruption and anti-money laundering and the enforcement ofanti-corruption regulations and measures. Brazil’s anticorruption law, which came into effect in 2014 establishes liability for Brazilian companies that commit acts against Brazilian or foreign public administrations, including acts relating to tender processes and administrative contracts. As a company that has public entity customers and participates in public bidding processes, we have increased risk exposure to potential misconduct. In addition, we have been historically engaged in oil and gas business activities in Brazil, a sector that has been the specific focus of governmental investigations, including the so calledLava Jato investigations centered on Petrobras and its affiliates.

125

Under the leadership of our current CEO, Mr. Sergio Pedreiro, who was appointed in early 2015, we have devoted substantial efforts to improve our governance, internal controls and integrity programs and policies in order to address perceived weaknesses, including by hiring a new chief compliance officer in 2015, strengthening our compliance and internal control systems and investing in our information systems and information technology infrastructure. For further information regarding our code of ethics and anticorruption policy, see “Item 6.C. Directors, Senior Management and Employees—Board Practices—Code of Ethics and Anti-Corruption Policy.”

However, notwithstanding our recent compliance efforts, we (including Soma), our founder Mr. Wilson Quintella Filho, who remains a minority shareholder, and certain other entities formerly affiliated with us, have been subject to, or mentioned in connection with, allegations or investigations of misconduct, including actions by the Brazilian tax authorities, the Brazilian Federal Police and the Brazilian Federal Prosecutor.

For further information regarding the risks relating to the circumstances described herein, see “Item 3.D. Key Information—Risk Factors— Risks Related to Compliance and Control.”

Allegations and Investigations Regarding our Supply Relationships

In the context of allegations of improper payments in connection with theso-calledLavo Jatooperations in Brazil, the integrity of our supply relationships has been a core focus of ours in recent years. We have received numerous inquiries and requests for information from the relevant Brazilian authorities since 2014 regarding our supply relationships and, in response, we have initiated several internal review processes focused on payments to certain suppliers of interest.

As part of theLava Jatoinvestigation,in August 2014, we received a notice from the Brazilian Federal Prosecutor requesting information regarding our commercial relationship with Grupo Pragmática, a Brazilian management consulting firm used by us. Grupo Pragmática is owned by thebrother-in-law of Paulo Roberto Costa and was implicated in theLava Jatoinvestigation. In November 2014, a Brazilian parliamentary committee, established by the Brazilian Congress in connection withLava Jato-related investigations and operating independently of the Brazilian Federal Prosecutor, also requested information from us regarding our relationship with Grupo Pragmática. We provided the requested information and the parliamentary committee was disbanded in October 2015 without any additional requests addressed to, or action against, us.

Starting in 2015, BFRS initiated several inquiries related to payments to certain suppliers. We were not able to produce the required information to BFRS in all cases and with respect to all suppliers in question, which resulted in several tax infringement notices of a material amount. For a detailed description of our tax infringement notices, see “—Tax Proceedings” below.

We believe that the tax authorities are cooperating with other Brazilian authorities, including the Brazilian Federal Police and theLava Jato investigators, and BFRS have shared their findings with such authorities. Accordingly, civil, regulatory and criminal proceedings and, potentially, sanctions, fines and other penalties could emanate from these tax matters. For further information regarding the risks relating to the circumstances described herein, see “Item 3.D. Key Information—Risk Factors— Risks Related to Compliance and Control.”

As evidence of this collaborative effort between the Brazilian tax authorities and other governmental agencies, on March 1, 2018, the Brazilian Federal Police executed search warrants at a number of companies in the cities of São Paulo, Santos, Paulínia, Belo Horizonte and Lamim, including the premises of Soma and our landfill in Paulinia as well as our corporate offices and the residence of Mr. Quintella, our founder and the former chairman of our board of directors. This action formed part of theso-calledOperation Descarte effort of the Brazilian Federal Police working in conjunction with the Brazilian tax authorities within the ambit of the broaderLava Jato task force. The stated objective ofOperation Descarte is to dismantle criminal money laundering scheme focused on payments made by companies operating in the Brazilian waste management industry via a network of presumed shell companies. In furtherance of this goal, the Brazilian federal police’s search and seizure procedures on March 1, 2018 were focused on collecting documentation and other materials related to certain specified suppliers. One of the Brazilian federal police officials onsite furnished to senior managers at the Company a copy of an official document that lists 17 suppliers of interest. As part of this action, the Brazilian federal police confiscated numerous hard copy and electronic files from our offices. As a matter of fact, on December 3, 2018, BFRS issued a new notice of infraction against us based on pieces of evidence collected by the federal police duringOperação Descarte.

126

On January 31, 2019, the Brazilian federal police executed search warrants at various locations in the State of São Paulo, including at our corporate headquarters. We understand this action was part of investigations related to contracts previously entered into in the period between 2008 and 2014 between ourselves and some of our former subsidiaries and Transpetro, and has been launched as a result of a plea bargain agreement entered into by Mr. Sergio Machado, the former CEO of Transpetro. As part of this police operation, temporary arrest warrants were also executed leading to, among others, the arrest of the founder and former chairman of Estre and a former senior employee of the Company.

Based on our historical experience, we may receive additional tax infringement charges in the future in relation to other suppliers, facts or periods, particularly as the statute of limitations related to such matters approaches expiration. Any of these tax infringement charges may involve additional criminal and regulatory actions and governmental inquiries alleging improper conduct in relation to these suppliers, any of which could have a material adverse effect on us.

Historical Internal Evaluation Processes Related to Supply Relationships

Considering the above, we have periodically conducted internal review processes with varying scopes to assess the integrity of our supplier relationships and effectiveness of our internal control procedures.

At the direction of our General Counsel, we hired in November 2015 an audit and investigation consultant to conduct a review of documentation concerning our historical transactions in the 2010 to 2015 period with those suppliers named at that point in the tax infringement notices and certain additional suppliers implicated in theLava Jatoinvestigations or identified by our independent auditors or our compliance division. The consultant did not find in its review any definitive evidence of improper payments; however, it did identify several past weaknesses in our internal controls and resulting inadequacies of documentation. While the findings of such review were ultimately inconclusive, we proactively terminated our commercial arrangements with almost all suppliers subject to this review.

In view of the inconclusive findings resulting from the initial review of certain of our supply arrangements, at the direction of our independent Brazilian legal counsel, we engaged a separate audit and investigation consultant in November 2016 (i) to further review documentation concerning transactions with our suppliers, expanding the scope of the work in terms of the number of suppliers analyzed and extending the covered period from 2010 through 2016, and (ii) to verify the efficiency of our updated internal control and management systems and to assess our inventory.

In their review of documents regarding our transactions with the identified suppliers during the 2010 to 2016 period, the second consultant once again did not find conclusive evidence of improper transactions. They concluded, however, that certain disbursements we made from 2010 to 2014 were not properly supported by documentation.

As a result of these findings, in 2016 we proactively terminated our commercial relationship with the majority of the suppliers subject to the earlier investigations that provided services that were not properly documented. In addition, on the basis of the findings of the independent consultants, our management made an accounting adjustment resulting in thewrite-off of property, plant and equipment items totaling R$44.0 million relating to payments we made for goods and services that could not be properly documented. See “Item 5.A. Operating and Financial Review and Prospects—OperatingResults—Write-off of Property, Plant and Equipment” for further information regarding the write-offs.

Soma was not considered in the scope of either our 2015 or 2016 internal evaluations of supplier relationships.

Operation Descarte—Special Committee Internal Evaluation

Following the receipt of tax infringement notices at the conclusion of 2017 as described below, we, at the direction of our general counsel, engaged a forensic services firm to review Soma’s relationships with certain suppliers. This investigation was only in the preliminary stages when the Brazilian federal police searched our corporate offices, our landfill in Paulinia and the premises of Soma on March 1, 2018.

In the aftermath of the events of March 1, 2018, we significantly broadened the scope of the internal evaluation process at the direction of a newly constituted special committee comprised of independent members of our board of directors for the specific purpose of evaluating our supply relationships and related matters across our organization, including at Soma and our joint ventures. This internal evaluation process was conducted by Brazilian and international external legal counsel working together with external forensic service providers.

The internal evaluation procedures involved the collection and review of relevant document and materials from past and present employees, interviews of persons of interest and a forensic analysis of financial transactions. As a result, we determined that there were payments made to certain suppliers, particularly through Soma, for which there was insufficient evidence that goods and services were provided. Considering these findings, we made several significant adjustments to our audited financial statements, including the restatement of our financial statements as of and for the years ended December 31, 2015 and 2016 as well as the establishment of additional tax provisions as of and for the year ended December 31, 2017 corresponding to the risk of probable tax loss emanating from our payments to these suppliers. For additional information, see “Item 5.A. Operating and Financial Review and Prospects—Operating Results—Internal Evaluation Process and Previous Restatement of Financial Statements.”

Based on the findings of the internal evaluation process, we intend to make certain adjustments to our compliance infrastructure to strengthen the independence of our compliance function across our organization, including all our subsidiaries and joint ventures. For additional information regarding our intended remediation efforts, see “Item 15. Controls and Procedures.”

Allegations and investigations involving Estaleiro Rio Tietê Ltda. (“ERT”), a former affiliate entity of ours engaged in the oil and gas sector

Our business activities in the oil and gas sector commenced in 2008 with the creation of Estre Petróleo. Estre Petróleo formed part of a consortium called ERT, primarily engaged in the construction and manufacture of river barges and pushers. Through Estre Petróleo, we used to own 50% of ERT and jointly controlled the entity.

We no longer have any affiliation with ERT. In October 2011, when BTG Pactual and Angra became our shareholders, we ceased participation in ERT via the transfer of Estre Petróleo’s interest in ERT to Mr. Quintella. Furthermore, in September 2014, Mr. Quintella exchanged certain of the Company’s common shares owned by him for all of the shares issued by Estre O&G, then held by us. At that time, Estre O&G was a one of our wholly-owned consolidated subsidiaries, and Estre O&G, in turn, had a 100% interest in Estre Petróleo. As a result, since the closing of this transaction in 2014, we no longer hold any equity interest in Estre O&G or Estre Petróleo, which are now controlled by Mr. Quintella. For additional information, see “Item 4.A. Information on the Company—History and Development—Recent Divestments and Acquisitions—Sale of Interest in Estrans Óleo e Gás Holding S.A.”

In 2010, ERT won a significant public bid to develop and build 20 river convoys comprising of 80 barges and 20 pushers to transport ethanol along the Tietê-Parana waterway. The bid was held by Petrobras Transporte S.A. (“Transpetro”), a fully owned subsidiary of Petrobras engaged in the transportation and storage of oil and byproducts. This contract was valued at R$464 million and ERT won the bid by submitting a proposal of R$432.3 million. In October 2014, at a time when we were no longer affiliated with ERT, the Brazilian Federal Prosecutor filed a civil action against us and ERT, representing the culmination of an ongoing civil inquiry initiated in 2013, alleging acts of administrative misconduct in connection with the ERT consortium’s winning bid for the 2010 contract. In connection with this claim, the Federal Public Prosecutor sought the annulment of administrative acts and contracts which benefited ERT and damages in the amount equal to all the payments that ERT received after executing the contract, including the down payment of R$21.9 million by the Brazilian merchant navy fund. The claims against us and ERT remain outstanding as of the date of this annual report.

128

In December 2015, the Brazilian Federal Police searched our offices and the offices of ERT. As part of the search of our headquarters, the Brazilian Federal Police only procured an electronic copy of the contract between ERT and Transpetro and no other documents or assets of ours were seized.

In February 2016, the independent federal accountability office (Tribunal de Contas da União) (“TCU”), which assists the Brazilian Congress in exercising external audits over the executive branch, presented its report regarding the winning 2010 bid of the ERT consortium for the Petrobras contract and concluded that the allegations of misconduct described above were unfounded. The decision of the TCU is not binding on the Brazilian Federal Prosecutor’s claims described above.

In June 2016, we were cited in the plea bargain agreement of Mr. Sergio Machado, the former CEO of Transpetro. In his testimony, Mr. Machado claims that ERT paid bribes of an undisclosed amount on a frequent basis prior to Mr. Machado leaving Transpetro in 2014.

As a consequence of a plea-bargain signed by Mr. Sergio Machado, on January 31, 2019, the Federal Police in Curitiba launched the Operation Quinto Ano to investigate crimes of corruption and money laundering involving contracts with TRANSPETRO, Estre and it former subsidiaries. In this operation, Mr Wilson Quintella Filho was temporary arrested.

As of the date of this annual report we do not know whether ERT has been charged with any criminal misconduct or been informed that any such charges are contemplated.

Allegations and investigation involving Mr. Wilson Quintella Filho, our founder

Mr. Quintella is our founder and the former chairman of our board of directors. Mr. Quintella resigned from our board in connection with the Transaction, and his percentage ownership in our company decreased to 5.9%. For additional information, see “Item 10.C. Additional Information—Material Contracts—The Transaction.”

Mr. Paulo Roberto Costa, Petrobras’ former director of refining and supply, was targeted in theLava Jato investigations and was convicted of money laundering and racketeering charges for his role in the Petrobras scandal. In September 2014, Mr. Costa named our company and Mr. Quintella in testimony provided as part of his plea bargain, which effectively reduced Mr. Costa’s sentence following his conviction. In his testimony, Mr. Costa alleged that Fernando Antônio Falcão Soares, a Brazilian lobbyist known as Fernando Baiano, introduced him to Mr. Quintella and, through Mr. Soares, Mr. Costa received payments of R$1.4 million in cash between 2011 and 2012. Mr. Costa indicated in his testimony that these payments were not in connection with any particular public bids and were merely an expression of gratitude. Mr. Quintella was also named in the plea bargain agreement of Mr. Sergio Machado in June 2016. The former CEO of Transpetro alleged that Mr. Quintella was involved in a bribery scheme involving Transpetro, while Mr. Machado was a senior executive at the Petrobras affiliate. Mr. Machado left Transpetro in 2014.

In December 2015, in connection with investigations involving ERT, the Brazilian Federal Police searched not only the offices of ERT, but also the home and business of Mr. Quintella. In connection with this search, the personal electronic devices of Mr. Quintella were seized by the Brazilian Federal Police. On March 1, 2018, Mr. Quintella’s home in São Paulo was again searched as part ofOperation Descarteand Mr. Quintella was arrested.

On January 31, 2019, the Federal Police in Curitiba launched Operation Quinto Ano to investigate crimes of corruption and money laundering involving contracts between Transpetro and Estre and its former subsidiaries. In the course of this operation, Mr. Quintella was temporarily arrested.

129

On March 1, 2019, the federal prosecutor’s office filed a criminal complaint against Mr. Quintella and other former senior employees of the Company, whereby the prosecutors presented an indicative amount of at least R$79.6 million to be claimed from the individuals in connection with the alleged wrongdoing. In the future, similar claims could be made on civil compensation grounds against the Company.

Other allegations and investigations of improper payments involving us

In his September 2014 testimony referenced above, which was provided as part of his plea bargain, Mr. Costa named not only Mr. Quintella, but also referenced our company. Furthermore, in November 2015, the Brazilian Federal Police seized a document dating from 2010 at the residence of Mauricio Bumlai, a Brazilian entrepreneur, that mentioned us in relation to alleged corrupt practices. In addition, in June 2016, we were cited in the plea bargain agreement of Mr. Sergio Machado, the former CEO of Transpetro, who alleged that, like ERT, we and Pollydutos, a former indirect subsidiary of ours, paid bribes on a frequent basis while Mr. Machado led Transpetro and before leaving his post at the Petrobras affiliate in 2014.

As of the date of this annual report and to our best knowledge, neither we nor Pollydutos are the focus of any investigations relating to the above, and neither we nor Pollydutos have been charged with any misconduct or been informed that any such charges are contemplated.

In addition, as a result of our historical engagements in the oil and gas business in Brazil with Petrobras as a customer and client, our management decided to instruct the investigation consultant engaged in November 2016 to separately analyze our commercial relationship with Petrobras, in particular all bidding processes in which we or any of our affiliates were successful and as a result of which services to Petrobras or any of its affiliates were or are provided. This review of our dealings with Petrobras was concluded in January 2018 and the investigation consultant identified a number of suppliers that provided goods and services in connection with our Petrobras engagements. These suppliers were then included in the internal evaluation process described above and the respective supply relationships were evaluated across our organization, including at Soma and our joint ventures.

Tax Proceedings

Overview

As of December 31, 2018, we were involved in 10 tax proceedings involving an estimated aggregate amount of R$346.0 million. Based on the advice of our external Brazilian legal counsel, we did not establish any provisions in relation to these matters. For all of these proceedings the risk of loss was possible.

Our most significant tax proceedings relate to tax infringement notices from the BFRS alleging our failure to pay the full amount of federal taxes due for a specified period on the assumption that we understated our taxable income for such periods due to alleged impermissible deductions arising from payments made to certain suppliers.

In 2018, we were able to definitively settle the majority of our tax debts through the consolidation of the Special Tax Regularization Program (PERT) and Tax Regularization Program (PRT), according to which debts due through April 30, 2017 were eligible for settlement.

However, by the end of 2018, the Company and Cavo received additional tax infringement notices of material value, also related to alleged impermissible deductions made as a result of unsupported payments made to certain suppliers. These additional tax assessments are no longer eligible for participation under any of the Tax Amnesty Programs, as further described below. Based on the analysis of the tax infringement notices received, our external Brazilian legal counsel in connection with the Company’s legal department concluded that the likelihood of any materialization of a loss should be considered as possible, and as such, no provision for contingency in relation to these tax proceedings was recorded.

130

We expect receive additional tax infringement notices from 2014 to 2016 related to similar matters in small amounts.

Settlement Through Brazilian Tax Regularization Program (PRT)

In May 2017, we entered into the Brazilian Tax Regularization Program established by Brazilian Provisional Measure 766/2017. The program permitted us to settle our tax debts, including payments of principal, interest and penalties assessed in a total amount of R$529.7 million, consisting of the following:

•

Federal taxes past due in the total amount of R$160.6 million;

•

Disputed amounts subject to tax infringement notices from the BFRS in an amount of R$174.0 million, as further described below; and

•

Amounts already subject to repayment under other federal tax repayment programs, converted to participation under the Brazilian Tax Regularization PRT Program due to its more favorable terms, in the total amount of R$195.1 million.

In June 2018, we conducted the consolidation of PRT Program, on which we performed the following:

•

Inclusion of additional tax liabilities on the PRT by a total amount of R$113.7 million; and

•

Decrease of the tax loss carryforward used to settle the tax liability under the program from R$370.1 million to R$282.3 million.

Our remaining balance due under the PRT Program as of December 31, 2018 is payable as follows:


Year of maturity	Amount Due
	(in R$ millions)
2019		46.5
2020		46.5
2021		46.5
2022 and following years		134.2

Total		273.7

Further Settlement Through Brazilian Special Tax Regularization Program (PERT Program)

In July 2017, we participated in an additional tax amnesty program – the Brazilian Special Tax Regularization Program (“PERT”) pursuant to which we were able to settle further tax debts in the total amount of R$245.6 million (including interest and penalties) related to tax amounts due in the months of December 2016 through April 2017, as follows:

•

federal taxes past due in the total amount of R$134.9 million;

•

tax provision balance of federal taxes (including income tax, social contributions and property taxes, among others) due in prior periods concerning one of our partially-owned subsidiaries in the total amount of R$6.7 million included in August, 2017; and

•

IOF taxes, which is a Brazilian tax on financial operations, for the period from October 2012 to March 2017 in the total amount of R$103.9 million related to intercompany loans,which we included in the program in September 2017.

In December 2018, we conducted the PERT consolidation process, in connection with which we performed the following actions:

•

reclassification of R$48.0 million to other tax liabilities, and reversal of R$5.9 million of taxes that were initially included in the PERT that were not eligible for inclusion in the PERT;

•

exclusion of R$9.8 million in tax liabilities from out of the PERT Program due to usage of income tax and social contribution tax credits to compensate such tax liabilities;

•

reversal of penalties fines and interests by R$16.8 million; and

•

usage of tax loss carryforward by R$80.0 million to settle the tax liability under the program.

131

Our remaining balance due under the PERT Program as of December 31, 2018 is payable as follows:


Year of maturity	Amount Due
	(in R$ millions)
2019		0.6
2020		0.6
2021		0.6
2022 and following years		6.7

Total		8.5

Tax Infringement Notices

The Company and Cavo have received a tax infringement notice from the BFRS and have five relevant administrative proceedings related thereto, which are being discussed on the administrative level, as described below:

•

Tax infringement notice from BFRS, received by Cavo on December 10, 2017, aiming at the collection of amounts allegedly due to IRPJ, IRRF and CSLL, in the amount of R$90.6 million concerning transactions with a number of specified suppliers in relation to payments made in 2012 challenging the deductibility of payments made to these suppliers for which there is lack of sufficient evidence that good and services were actually provided.

•

Two tax infringement notice from BFRS, received by the Company, on December 22 and 27, 2017, aiming at the collection of amounts allegedly due to IRPJ, IRRF and CSLL, in the aggregate amount of R$121.8 million concerning transactions with a number of specified suppliers in relation to payments made between 2011 and 2015 challenging the deductibility of payments made to these suppliers for which there is lack of sufficient evidence that good and services were actually provided and also claiming payment of social security contributions on unsupported payments made to individual recipients. In November 2018, the amount was reduced to R$92.8 million as a result of a revision made by BRFS to the amounts collected.

•

Tax infringement notice from BFRS, received by Cavo on December 10, 2018, aiming at the collection of amounts allegedly due to IRPJ, IRRF and CSLL, in the amount of R$65.7 million concerning transactions with a number of specified suppliers in relation to payments made in 2013 challenging the deductibility of payments made to these suppliers for which there is lack of sufficient evidence that good and services were actually provided.

•

Tax infringement notice from BFRS, received by the Company on December 4, 2018, aiming at the collection of amounts allegedly due to IRPJ, IRRF and CSLL, in the amount of R$53.6 million concerning transactions with a number of specified suppliers in relation to payments made in 2013 challenging the deductibility of payments made to these suppliers for which there is lack of sufficient evidence that good and services were actually provided.

The Brazilian Tax Regularization Programs in which we participated to settle certain of our historical tax assessments may no longer be available to settle new tax infringement matters, including those infringement notices received by Cavo and the Company in December 2017 and December 2018. There is no guarantee that an additional tax amnesty programs will be offered by the Brazilian government on favorable terms, or at all, in the foreseeable future to settle these new or future tax assessments.

Based on advice of our external legal counsel, who assessed the risk of a potential loss as possible, we did not records provisions in the aggregate amount of R$309.3 million corresponding to IRPJ, CSLL and IRRF taxes levied by the BFRS in relation to these tax assessments received by the Company and Cavo.

We did, however, establish provisions in the amount of R$18.7 million in 2018 (R$122.7 million in 2017) corresponding mainly to our management’s assessment of the probable risk of loss emanating from future tax assessments based on the findings of our Internal Evaluation Process and the advice of our independent Brazilian legal counsel.

132

For additional information regarding our tax proceedings and participation in the Brazilian Tax Regularization Program, see notes 17 and 20 to our audited financial statements included elsewhere in this annual report.

Public and Class Action Proceedings

As of December 31, 2018, we were involved in a total 25 public and class action proceedings, in which the total aggregate potential loss was approximately R$166.1 million. We estimated that the risk of loss for three of these proceedings was probable, involving an aggregate amount of R$1.2 million (R$2.2 million as of December 31, 2017). For sixteen of these proceedings, the risk of loss was possible, involving claims totaling an aggregate amount of R$98.7 million.

The allegations arising from our relevant public and class action proceedings stem from our participation in public bids and the resulting service contracts entered into with public entities, as well as the authorizations and orders that were issued in connection with these public bids. Most of the proceedings were initiated by the relevant states’ public prosecutor’s office or the Federal Public Prosecutor’s office against us or certain of our affiliates (often prompted by one of our competitors) alleging misconduct or regulatory breaches during specific public bidding processes and are typical for companies operating in the Brazilian waste management business. The proceedings challenge the authorizations, orders and contracts that were executed as a result of winning the respective public bid, in addition to requesting the restitution of any value or benefit gained. These proceedings are ongoing and we continue to assert our defense in each of them. We do not believe that these ordinary course proceedings pose a significant risk to the company.

One of our most significant public proceedings relates to our cleaning services with the municipality of Taboão da Serra. On March 14, 2013,the São Paulo State Prosecutor’s Office filed a lawsuit challenging the legal enforceability of five agreements entered into between the municipality of Taboão da Serra and our subsidiary Viva for public cleaning services, with a total aggregate value of R$154.1 million. In 2015, the party that sold us Viva in 2012, who is a codefendant in this case, proposed a precautionary action requesting an independent reevaluation of the amounts claimed by the Prosecutor’s Office. Even though this independent reevaluation has not been concluded, our independent legal counsel determined that the risk of loss for this proceeding is possible and estimates the amount involved to be approximately R$39.2 million. As the risk of loss is possible, we have not established any provisions for this proceeding.

Labor Proceedings

As of December 31, 2018, we were party to 1,623 labor proceedings, in which the total aggregate amount claimed was approximately R$68.9 million. As of December 31, 2018, we estimated that the risk of loss was possible for 755 of these proceedings involving an aggregate amount of R$26.3 million, and probable for 512 of these proceedings, involving a total aggregated amount of R$31.4 million.

Most of our labor proceedings were filed by former employees or outsourced employees. The main allegations made concern amounts allegedly owed by us due to: overtime, indemnities based on Brazilian labor laws, exposure to hazardous conditions, remuneration matters and health and safety issues related to our waste collection operations, among other matters.

The volume and nature of the labor proceedings described above are, we believe, consistent with those of other Brazilian businesses in our sector or with similar work force characteristics.

Civil and Arbitral Proceedings

As of December 31, 2018, we were involved in 99 ordinary course civil proceedings, in which the total aggregate amount claimed was approximately R$14.4 million and no judicial deposits were made.

We estimated that the risk of loss for 20 of these proceedings was probable, in which the total aggregate amount claimed was approximately R$3.7 million. For 65 of these proceedings the risk of loss was possible, involving claims totaling an aggregate amount of R$10.3 million. Most of these legal proceedings were initiated by our suppliers and involve garbage truck accidents inherent in our solid waste collection operations.

133

In addition, the Company entered into an agreement related to arbitration proceeding filed by Neptune Assesoria e Engenharia Ambiental Ltda. alleging that they are owed commissions due to their participation as an advisor in our (i) investment in Advanced Disposal Services (ADS) through Highstar, an investment vehicle, and (ii) divestment of ADS / Highstar to BTG Pactual.

Environmental and Regulatory Proceedings

As of December 31, 2018, we were involved in approximately 21 environmental proceedings, in which the total aggregate amount claimed was approximately R$0.7 million. These proceedings include public civil actions and collection actions concerning our landfill operations and are typical for companies operating in the Brazilian waste management business.

As of December 31, 2018, we estimated that the risk of loss for 8 of these proceedings was possible, involving claims totaling an aggregate amount of R$0.7 million, for 11 of these proceedings the risk of loss was remote, totaling an aggregate amount of R$8 thousand, and, two of these proceedings have a probable risk of loss, involving an amount of R$1.5 thousand. In addition, we are under investigation in certain routine civil inquiries started by the Public Prosecutor’s Office to monitor environmental licensing processes. We are also involved in administrative proceedings arising out of ourday-to-day operations, such as landfill odors or other environmental issues.

On February 24, 2011, the Public Prosecutor’s Office of São Paulo filed a public action lawsuit challenging the operation of our Itapevi landfill alleging our noncompliance with local environmental regulations, including the landfill’s proximity to water springs and local communities as well as allegations of deforestation, among other claims. The Public Prosecutor’s Office is requesting that we cease and remediate all deforestation activities, restore the vegetation in the area to its original condition and pay a fine. In addition, on the same date, a public class action was filed by a group of individuals related to the same activities at our Itapevi landfill, and the judge presiding over public action lawsuit described above ordered there to be a joint judgment for these two matters.

On November 12, 2018, a court decision on the abovementioned judicial proceedings declared the nullity and therefore called for the cancelation of the installation license issued by CETESB and also determined that (i) the company suspends the disposal of solid waste in the landfill, breach of which injunction would result in a daily fine of R$100 thousand, (ii) after six months of the final immutable decisionof the lawsuit, ,the company presents a Plan for the Recovery of Degraded Areas to CETESB and IBAMA; and (iii) within 30 days after the approval of the Plan, the Company start working on its execution under penalty of a fine in the amount of R$10 million. Such injunctions are only enforceable upon the company once a final and immutable decision has been made by the court, which we estimate to last a few years, depending on subsequent events of the lawsuit. We estimate that the risk of loss for these proceedings was possible, but no value was attributed as the decision merely imposed the aforementioned obligations on the Company but did not order any payment to be made and it is pending further court review.

Dividend Policy

Other than as disclosed elsewhere in this annual report, we currently expect to retain all future earnings for use in the operation and expansion of our business and do not plan to pay any dividends on our ordinary shares in the foreseeable future. The declaration and payment of any dividends in the future will be determined by our board of directors in its discretion, and will depend on a number of factors, including our earnings, capital requirements, overall financial condition, applicable law and contractual restrictions. Cash dividends on our common shares, if any, will be paid in U.S. dollars.

We have not distributed any dividends in the past five years.

Each ordinary share and each Class B Share entitles the holder to one vote on all matters upon which the holders are entitled to vote. Voting at any general meeting is by show of hands, unless voting by way of poll demanded by the chairman of the board of directors or any shareholder present in person or by proxy.

A quorum required for a general meeting requires the presence in person or by proxy of persons holding in aggregate not less thanone-third in nominal value of all shares issued by us.

A special resolution will be required for important matters such as our merger or consolidation, reduction of our capital or any capital redemption reserve fund, change of name or making changes to our Memorandum and Articles or our voluntary winding up.

An ordinary resolution of our shareholders requires the affirmative vote of a simple majority of the votes cast at a quorate general meeting, while a special resolution requires the affirmative vote of at leasttwo-thirds of the votes cast at a quorate general meeting. Any action required or permitted to be taken at our general meeting may not be taken by resolution in writing of the shareholders.

Variation of rights of shares

All or any of the rights attached to any class of our shares (unless otherwise provided by the terms of issue of the shares of that class) may, whether or not we are being wound up, be varied without the consent of the holders of the issued shares of that class where such variation is considered by our board of directors not to have a material adverse effect upon such rights; otherwise, any such variation shall be made only with the consent in writing of the holders of not less than two thirds of the issued shares of that class, or with the sanction of a resolution passed by a majority of not less than two thirds of the votes cast at a separate meeting of the holders of the shares of that class.

Transfer of Ordinary Shares

Any shareholder may transfer all or any of his or her ordinary shares or Class B Shares by an instrument of transfer in the usual or common form or any other form prescribed by the Designated Stock Exchange or as otherwise approved by the board of directors. The transferor shall be deemed to remain the holder of such ordinary shares or Class B Shares until the name of the transferee is entered in the register of members.

In addition, the Memorandum and Articles prohibit the transfer of shares in breach of the applicable rules of the SEC and federal and state securities laws of the U.S.

Redemption of Shares

We may issue shares on terms that such shares are subject to redemption, at our option or at the option of the holders thereof, on such terms and in such manner as may be determined, before the issue of such shares, by a special resolution of our shareholders. We may also repurchase any of our shares provided that the manner and terms of such purchase have been approved by our board of directors or are otherwise authorized by our Memorandum and Articles. Under the Companies Law, the redemption or repurchase of any share may be paid out of a company’s profits or a share premium account, or out of the proceeds of a fresh issue of shares made for the purpose of such redemption or repurchase, or, if so authorized by our Memorandum and Articles, out of capital if we can, immediately following such payment, pay our debts as they fall due in the ordinary course of business. In addition, under the Companies Law no such share may be redeemed or repurchased (i) unless it is fullypaid-up, (ii) if such redemption or repurchase would result in there being no shares in issue, or (iii) if the company has commenced liquidation. In addition, we may accept the surrender of any fully paid share for no consideration.

137

Call on Shares and Forfeiture of Shares

Our board of directors may from time to time make calls upon shareholders for any amounts unpaid on their ordinary shares in a notice served to such shareholders at least 14 days prior to the specified time of payment. The ordinary shares that have been called upon and remain unpaid are subject to forfeiture.

Changes in Capital

We may from time to time by ordinary resolution:

•

increase the share capital by such sum as the resolution prescribes;

•

consolidate and divide all or any of our share capital into shares of a larger amount than our existing shares;

•

convert all or any of ourpaid-up shares into stock and reconvert that stock intopaid-up shares of any denomination;

•

sub-divide our existing shares into shares of a smaller amount than that fixed by our Memorandum and Articles or into shares without par value; and

•

cancel any shares that 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.

Subject to the Companies Law and our Memorandum and Articles, our shareholders may by special resolution reduce our share capital and any capital redemption reserve.

Liquidation

On our winding up, if the assets available for distribution among our shareholders shall be insufficient to repay all of thepaid-up capital, the assets will be distributed so that, as nearly as may be, the losses are borne by our shareholders in proportion to the par value of the shares held by them. If the assets available for distribution among our shareholders shall be more than sufficient to repay the whole of the share capital at the commencement of the winding up, the surplus will be distributed among our shareholders in proportion to the par value of the shares held by them at the commencement of the winding up, subject to a deduction from those shares in respect of which there are monies due, of all monies payable to us for unpaid calls or otherwise.

Board of Directors

Appointment and removal

Our management is vested in a board of directors. Our Memorandum and Articles provide that there shall be a board of directors consisting of no less than one director, provided that the directors may increase or decrease the limits on the number of directors. Our board of directors currently consists of ten directors and had no vacancy.

The directors shall be divided into three classes designated as Class I, Class II and Class III, respectively, with as nearly equal a number of directors in each group as possible as at the time of such designation. Directors shall be assigned to each class in accordance with a resolution or resolutions adopted by the board of directors. Director nominees shall be elected by an ordinary resolution in accordance with our Memorandum and Articles at each of our annual general meetings to fill the seats of those directors whose terms expire at such annual general meeting and the persons to stand for election at each of our annual general meetings shall be nominated by the directors, after consultation with the nominating and corporate governance committee (if such committee is established). At the 2018 annual general meeting, the term of office of the Class I directors expired and the Class I directors were elected for a full term of three years, comprising of Mr. Gesner Oliveira, Mr. Ricardo Pelucio and Mr. Fabio Pinheiro. At the 2019 annual general meeting, the term of office of the Class II director, Dr. Klaus Pohle, shall expire. At the 2020 annual general meeting, the term of office of the Class III directors, Mr. Pedreiro and Mr. Trevor shall expire. At each succeeding annual general meeting, directors shall be elected for a full term of three years to succeed the directors of the class whose terms expire at such annual general meeting.

138

Any and all vacancies in the board of directors, including, without limitation, by reason of an increase in the size of the board of directors, or the death, resignation, disqualification or removal of a director, will be filled solely and exclusively by the affirmative vote of a majority of the remaining directors then in office, even if less than a quorum. Any director so appointed shall hold office until the expiration of the term of the class of directors in which the new directorship was created or the vacancy occurred or until his or her earlier death, resignation or removal. A director may be removed from office by the shareholders by special resolution only for “cause” (as defined in our Memorandum and Articles).

The board of directors will determine the class or classes to which any increased or decreased number of directors will be apportioned, provided that no decrease on the number of directors shall shorten the term of any incumbent director.

Indemnity of directors and officers

Our Memorandum and Articles provide that the board of directors and officers shall be indemnified from and against all liability which they incur in execution of their duty in their respective offices, except liability incurred by reason of such director’s or officer’s actual fraud or willful default.

Differences in Corporate Law

The Companies Law of the Cayman Islands is modelled after similar laws in England and Wales but does not follow recent statutory enactments in England and Wales. In addition, the Companies Law of the Cayman Islands differs from laws applicable to U.S. corporations and their shareholders. Set forth below is a summary of the significant differences between the provisions of the Companies Law of the Cayman Islands applicable to us and the laws applicable to companies incorporated in the United States and their shareholders.

Mergers and Similar Arrangements

The Companies Law of the Cayman Islands permits mergers and consolidations between Cayman Islands companies and between Cayman Islands companies andnon-Cayman Islands companies.

For these purposes, (a) “merger” means the merging of two or more constituent companies and the vesting of their undertaking, property and liabilities in one of such companies as the surviving company and (b) a “consolidation” means the combination of two or more constituent companies into a consolidated company and the vesting of the undertaking, property and liabilities of such companies in the consolidated company. In order to effect such a merger or consolidation, the directors of each constituent company must approve a written plan of merger or consolidation, which must then be authorized by (a) a special resolution of the shareholders of each constituent company and (b) such other authorization, if any, as may be specified in such constituent company’s articles of association. The plan must be approved by the directors of each constituent company and filed with the Registrar of Companies together with a declaration as to: (1) the solvency of the consolidated or surviving company, (2) the merger or consolidation is bona fide and not intended to defraud unsecured creditors of the constituent companies; (3) no petition or other similar proceeding has been filed and remains outstanding and no order or resolution to wind up the company in any jurisdiction, (4) no receiver, trustee, administrator or similar person has been appointed in any jurisdiction and is acting in respect of the constituent company, its affairs or property, (5) no scheme, order, compromise or similar arrangement has been entered into or made in any jurisdiction with creditors; (6) a list of the assets and liabilities of each constituent company; (7) thenon-surviving constituent company has retired from any fiduciary office held or will do so; (8) that the constituent company has complied with any requirements under the regulatory laws, where relevant; and (9) an undertaking that a copy of the certificate of merger or consolidation will be given to the members and creditors of each constituent company and published in the Cayman Islands Gazette.

Dissenting shareholders have the right to be paid the fair value of their shares (which, if not agreed between the parties, may be determined by the Cayman Islands’ court) if they follow the required procedures, subject to certain exceptions. Court approval is not required for a merger or consolidation which is effected in compliance with these statutory procedures.

139

In addition, there are statutory provisions that facilitate the reconstruction and amalgamation of companies, provided that the arrangement in question is approved by a majority in number of each class of shareholders and creditors with whom the arrangement is to be made, and who must in addition representthree-fourths in value of each such class of shareholders or creditors, as the case may be, that are present and voting either in person or by proxy at a meeting, or meetings convened for that purpose. The convening of the meetings and subsequently the arrangement must be sanctioned by the Grand Court of the Cayman Islands. While a dissenting shareholder would have the right to express to the court the view that the transaction should not be approved, the court can be expected to approve the arrangement if it satisfies itself that:

•

we are not proposing to act illegally or ultra vires and the statutory provisions as to majority vote have been complied with;

•

the shareholders have been fairly represented at the meeting in question;

•

the arrangement is such that may be reasonably approved by an intelligent and honest man of that class acting in respect of his interest; and

•

the arrangement is not one that would more properly be sanctioned under some other provision of the Companies Law of the Cayman Islands or that would amount to a “fraud on the minority.”

When a takeover offer is made and accepted by holders of 90.0% of the shares within four months, the offeror may, within atwo-month period, require the holders of the remaining shares to transfer such shares on the terms of the offer. An objection may be made to the Grand Court of the Cayman Islands but is unlikely to succeed unless there is evidence of fraud, bad faith or collusion.

If the arrangement and reconstruction are thus approved, any dissenting shareholders would have no rights comparable to appraisal rights, which might otherwise ordinarily be available to dissenting shareholders of U.S. corporations and allow such dissenting shareholders to receive payment in cash for the judicially determined value of their shares.

Shareholders’ Suits

Class actions are not recognized in the Cayman Islands, but groups of shareholders with identical interests may bring representative proceedings, which are similar. However, a class action suit could nonetheless be brought in a U.S. court pursuant to an alleged violation of U.S. securities laws and regulations.

In principle, we would normally be the proper plaintiff and as a general rule, whilst a derivative action may be initiated by a minority shareholder on our behalf in a Cayman Islands court, such shareholder will not be able to continue those proceedings without the permission of a Grand Court judge, who will only allow the action to continue if the shareholder can demonstrate that we have a good case against the Defendant, and that it is proper for the shareholder to continue the action rather than our board of directors. Examples of circumstances in which derivative actions would be permitted to continue are where:

•

a company is acting or proposing to act illegally or beyond the scope of its authority;

•

the act complained of, although not beyond the scope of its authority, could be effected duly if authorized by more than a simple majority vote that has not been obtained; and

•

those who control the company are perpetrating a “fraud on the minority.”

Corporate Governance

Cayman Islands law restricts transactions between the company and its directors unless there are provisions in the Articles of Association which provide a mechanism to alleviate possible conflicts of interest. Additionally, Cayman Islands law imposes on directors duties of care and skill and fiduciary duties to the companies which they serve. Our Articles of Association provide that directors who are in any way interested in a contract or transaction must declare the nature of their interest at or prior to a meeting of the board of directors. Following such declaration, a director may vote in respect of any contract or transaction notwithstanding his interest.

140

As a foreign private issuer, we are permitted to follow home country practice in lieu of certain NASDAQ corporate governance rules, subject to certain requirements. With effect from the date of this annual report, we follow home country practice that does not require us to obtain shareholder approval for issuing additional securities exceeding 20% of our outstanding ordinary shares. Disclosure on our corporate governance arrangements is disclosed elsewhere in this annual report.

Indemnification of Directors and Executive Officers and Limitation of Liability

The Companies Law of the Cayman Islands does not limit the extent to which a company’s articles of association may provide for indemnification of directors and officers, except to the extent that it may be held by the Cayman Islands courts to be contrary to public policy, such as to provide indemnification against civil fraud or the consequences of committing a crime. The Articles provide that the board of directors and officers shall be indemnified from and against all liability which they incur in execution of their duty in their respective offices, except liability incurred by reason of such directors’ or officers’ actual fraud or willful default. This standard of conduct is generally the same as permitted under the Delaware General Corporation Law for a Delaware corporation.

Insofar as indemnification for liabilities arising under the Securities Act may be permitted to our directors, officers or persons controlling us under the foregoing provisions, we have been informed that, in the opinion of the SEC, this indemnification is against public policy as expressed in the Securities Act and is therefore unenforceable.

Directors’ Fiduciary Duties

As a matter of Cayman Islands law, a director of a Cayman Islands company is in the position of a fiduciary with respect to the company. Accordingly, directors owe fiduciary duties to their companies to act bona fide in what they consider to be the best interests of the company, to exercise their powers for the purposes for which they are conferred and not to place themselves in a position where there is a conflict between their personal interests and their duty to the company. Accordingly, a director owes a company a duty not to make a profit based on his or her position as director (unless the company permits him or her to do so) and a duty not to put himself or herself in a position where the interests of the company conflict with his or her personal interest or his or her duty to a third party. In addition, directors of a Cayman Islands company must not therefore place themselves in a position in which there is a conflict between their duty to the company and their personal interests. However, this obligation may be varied by the company’s articles of association, which may permit a director to vote on a matter in which he has a personal interest provided that he has disclosed that nature of his interest to the board of directors. Our Articles of Association provide that directors who are in any way interested in a contract or transaction must declare the nature of their interest at or prior to a meeting of the board of directors. Following such declaration, a director may vote in respect of any contract or transaction notwithstanding his interest.

A director of a Cayman Islands company also owes to the company duties to exercise independent judgment in carrying out his functions and to exercise reasonable skill, care and diligence, which has both objective and subjective elements. Recent Cayman Islands case law confirmed that directors must exercise the care, skill and diligence that would be exercised by a reasonably diligent person having the general knowledge, skill and experience reasonably to be expected of a person acting as a director. Additionally, a director must exercise the knowledge, skill and experience which he actually possesses.

A general notice may be given at a meeting of the board of directors to the effect that (1) the director is a member or officer of a specified company or firm and is to be regarded as interested in any contract or arrangement which may after the date of the notice in writing be made with that company or firm; or (2) he is to be regarded as interested in any contract or arrangement which may after the date of the notice in writing to the board of directors be made with a specified person who is connected with him or her, will be deemed sufficient declaration of interest. This notice shall specify the nature of the interest in question. Following the disclosure being made pursuant to our Articles of Association and subject to any separate requirement under applicable law or the listing rules of NASDAQ, a director may vote in respect of any contract or arrangement notwithstanding his interest.

141

In comparison, under Delaware corporate law, a director of a Delaware corporation has a fiduciary duty to the corporation and its shareholders. This duty has two components: the duty of care and the duty of loyalty. The duty of care requires that a director act in good faith, with the care that an ordinarily prudent person would exercise under similar circumstances. Under this duty, a director must inform himself or herself of, and disclose to shareholders, all material information reasonably available regarding a significant transaction. The duty of loyalty requires that a director act in a manner he or she reasonably believes to be in the best interests of the corporation. He or she must not use his or her corporate position for personal gain or advantage. This duty prohibits self-dealing by a director and mandates that the best interest of the corporation and its shareholders take precedence over any interest possessed by a director, officer or controlling shareholder and not shared by the shareholders generally. In general, actions of a director are presumed to have been made on an informed basis, in good faith and in the honest belief that the action taken was in the best interests of the corporation. However, this presumption may be rebutted by evidence of a breach of one of the fiduciary duties. Should such evidence be presented concerning a transaction by a director, a director must prove the procedural fairness of the transaction, and that the transaction was of fair value to the corporation.

Shareholder Proposals

Under the Delaware General Corporation Law, a shareholder has the right to put any proposal before the annual meeting of shareholders, provided it complies with the notice provisions in the governing documents. The Delaware General Corporation Law does not provide shareholders an express right to put any proposal before the annual meeting of shareholders, but Delaware corporations generally afford shareholders an opportunity to make proposals and nominations provided that they comply with the notice provisions in the certificate of incorporation or bylaws. A special meeting may be called by the board of directors or any other person authorized to do so in the governing documents, but shareholders may be precluded from calling special meetings.

The Companies Law of the Cayman Islands provides shareholders with only limited rights to requisition a general meeting, and does not provide shareholders with any right to put any proposal before a general meeting. However, these rights may be provided in a company’s articles of association. Our Articles of Association provide that general meetings may be convened by a majority of the board of directors or requisitioned by holders of at least 10% in par value of our issued shares that carry the right to vote at general meetings. Pursuant to our Articles of Association, no business may be transacted at any general meeting, other than business that is either (a) specified in the notice of general meeting (or any supplement thereto) given by or at the direction of the directors (or any duly authorized committee thereof), (b) otherwise properly brought before a general meeting by or at the direction of the directors or (c) otherwise properly brought before a general meeting by any shareholder who (1) is a shareholder of record on both (x) the date of the giving of the notice by such shareholder provided for in the Articles and (y) the record date for the determination of shareholders entitled to vote at such general meeting and (2) complies with the notice procedures set forth in the provisions of the Articles of Association.

Cumulative Voting

Under the Delaware General Corporation Law, cumulative voting for elections of directors is not permitted unless the corporation’s certificate of incorporation specifically provides for it. Cumulative voting potentially facilitates the representation of minority shareholders on a board of directors since it permits the minority shareholder to cast all the votes to which the shareholder is entitled on a single director, which increases the shareholder’s voting power with respect to electing such director. As permitted under Cayman Islands law, our Articles of Association do not provide for cumulative voting. As a result, our shareholders are not afforded any less protections or rights on this issue than shareholders of a Delaware corporation.

Election and Removal of Directors

Under Delaware corporate law, unless otherwise specified in the certificate of incorporation or bylaws of a corporation, directors are elected by a plurality of the votes of the shares entitled to vote on the election of directors and may be removed with or without cause (or, with respect to a classified board, only with cause unless the certificate of incorporation provides otherwise) by the approval of a majority of the outstanding shares entitled to vote.

Under our Articles of Association, the directors shall be divided into three classes designated as Class I, Class II and Class III, respectively, with as nearly equal a number of directors in each group as possible as at the time of such designation. Directors shall be assigned to each class in accordance with a resolution or resolutions adopted by the board of directors. Director nominees shall be elected by an ordinary resolution in accordance with our Memorandum and Articles at each of our annual general meetings to fill the seats of those directors whose terms expire at such annual general meeting and the persons to stand for election at each of our annual general meetings shall be nominated by the directors, after consultation with the nominating and corporate governance committee (if such committee is established).

142

Under of Articles of Association, a director may be removed from office by the shareholders by special resolution only for “cause” (as defined in the Articles of Association). A director will be removed from office automatically if, among other things, he or she (1) becomes prohibited by law from being a director, (2) becomes bankrupt or makes an arrangement or composition with his creditors, (3) dies or is in the opinion of all hisco-directors, incapable by reason of mental disorder of discharging his duties as director, (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 of directors held during that period, and the remaining directors resolve that his/her office be vacated.

Transactions with Interested Shareholders

The Delaware General Corporation Law provides that; unless the corporation has specifically elected not to be governed by this statute, it is prohibited from engaging in certain business combinations with an “interested shareholder” for three years following the date that this person becomes an interested shareholder. An interested shareholder generally is a person or a group who or which owns or owned 15% or more of the target’s outstanding voting shares or who or which is an affiliate or associate of the corporation and owned 15% or more of the corporation’s outstanding voting shares within the past three years. This has the effect of limiting the ability of a potential acquirer to make atwo-tiered bid for the target in which all shareholders would not be treated equally. The statute does not apply if, among other things, prior to the date on which the shareholder becomes an interested shareholder, the board of directors approves either the business combination or the transaction which resulted in the person becoming an interested shareholder. This encourages any potential acquirer of a Delaware corporation to negotiate the terms of any acquisition transaction with the target’s board of directors.

Cayman Islands law has no comparable statute. As a result, we cannot avail ourselves of the types of protections afforded by the Delaware business combination statute. However, although Cayman Islands law does not regulate transactions between a company and its significant shareholders, it does provide that these transactions must be entered into bona fide in the best interests of the company and for a proper corporate purpose and a transaction may be subject to challenge if it has the effect of constituting a fraud on the minority shareholders.

Dissolution; Winding Up

Under the Delaware General Corporation Law, unless the board of directors approves the proposal to dissolve, dissolution must be approved by shareholders holding 100% of the total voting power of the corporation. If the dissolution is initiated by the board of directors it may be approved by a simple majority of the corporation’s outstanding shares. Delaware law allows a Delaware corporation to include in its certificate of incorporation a supermajority voting requirement in connection with dissolutions initiated by the board. Under Cayman Islands law, a company may be wound up by either an order of the courts of the Cayman Islands or by a special resolution of its members or, if the company resolves by ordinary resolution that it be wound up because it is unable to pay its debts as they fall due. The court has authority to order winding up in a number of specified circumstances including where it is, in the opinion of the court, just and equitable to do so.

Under the Companies Law of the Cayman Islands, our company may be dissolved, liquidated or wound up by a shareholder resolution passed by a majority of at leasttwo-thirds of the voting rights entitled to vote at a general meeting of our shareholders.

Variation of Rights of Shares

Under the Delaware General Corporation Law, a corporation may vary the rights of a class of shares with the approval of a majority of the outstanding shares of that class, unless the certificate of incorporation provides otherwise.

Under Cayman Islands law and our Articles of Association, all or any of the rights attached to any class of our shares (unless otherwise provided by the terms of issue of the shares of that class) may, whether or not we are being wound up, be varied without the consent of the holders of the issued shares of that class where such variation is considered by our board of directors not to have a material adverse effect upon such rights; otherwise, any such variation shall be made only with the consent in writing of the holders of not less than two thirds of the issued shares of that class, or with the sanction of a resolution passed by a majority of not less than two thirds of the votes cast at a separate meeting of the holders of the shares of that class.

143

Amendment of Governing Documents

Under the Delaware General Corporation Law, a corporation’s certificate of incorporation may be amended only if adopted and declared advisable by the board of directors and approved by a majority of the outstanding shares entitled to vote, and the bylaws may be amended with the approval of a majority of the outstanding shares entitled to vote and may, if so provided in the certificate of incorporation, also be amended by the board of directors. Under Cayman Islands law, our Articles of Association generally may only be amended by special resolution of no less thantwo-thirds of voting rights entitled to vote at a meeting of our shareholders.

Rights ofNon-Resident or Foreign Shareholders

There are no limitations imposed by our Articles of Association on the rights ofnon-resident or foreign shareholders to hold or exercise voting rights on our shares. In addition, there are no provisions in our Articles of Association governing the ownership threshold above which shareholder ownership must be disclosed.

C.	Material Contracts

In addition to the contracts described in other sections of this annual report, the following is a summary of the material contracts to which we are a party.

Registration Rights Obligations in connection with PIPE Subscription Agreements

On December 21, 2017, we issued 15,438,000 of our ordinary shares and 3,748,600 warrants to purchase ordinary shares at US$11.50 per share to certain institutional investors unaffiliated with us pursuant to a private investment in public equity, which we refer to as the PIPE Investment.

Pursuant to the PIPE Investment subscription agreement, we are required to file a new registration statement under the Securities Act registering the shares issued pursuant to the PIPE Investment within 30 days following the completion of the Merger, and must thereafter use our best efforts to have such registration statement be declared effective.

On January 24, 2018, the Registrant filed with the SEC theF-1 Registration Statement (as defined below under “Warrant Agreement” below). TheF-1 Registration Statement has become stale due to the age of the financial information included therein and the Registrant currently expects to file anF-3 Registration Statement (also defined below under “Warrant Agreement” below) in due course following the filing of this annual report on Form20-F. The Registrant currently anticipates that, upon the effectiveness of theF-3 Registration Statement, the prospectus included within theF-3 Registration Statement shall cover the resale of the ordinary shares that were issued in the PIPE Investment and the resale of the ordinary shares issuable upon exercise of the warrants issued in the PIPE Investment. Notwithstanding theF-1 Registration Statement having become stale, the securities that were issued pursuant to the PIPE Investment are entitled be sold bynon-affiliates of the Registrant pursuant to Rule 144 under the Securities Act, subject to the Registrant remaining current in its periodic reporting obligations under the Exchange Act.

Exchange and Support Agreement

Upon the closing of the Transaction, we, Estre USA and the holders of Class B Common Stock of Estre USA (other than those forfeited pursuant to the Forfeiture and Waiver Agreement) remained outstanding following consummation of the Merger, entered into the Exchange and Support Agreement, dated as of December 21, 2017 (the “Exchange and Support Agreement”). Pursuant to the terms of the Exchange and Support Agreement, the holders of the Class B Common Stock of Estre USA will have the right to, from time to time, commencing on the first anniversary of the closing of the Transaction, exchange any or all of their Class B Common Stock of Estre USA for the same amount of our ordinary shares. Upon such exchange, an equal number of our Class B Shares, which were received by the holders thereof in the Merger, held by the exchanging shareholder shall be automatically surrendered to us for no consideration and, accordingly, the exchanging shareholder shall cease to be a holder of such Class B Shares. The right to make such exchange will expire on the seventh anniversary of the date of the Exchange and Support Agreement.

144

Registration Rights andLock-Up Agreement

Upon the closing of the Transaction, the Registrant, certain persons and entities which held our ordinary shares and the Sponsor holding certain of the warrants issued by Estre USA to acquire shares of Class A Common Stock that were outstanding immediately prior to the closing of the Transaction, as converted in the Merger such that they represent the right to acquire the same number of our ordinary shares, at the same exercise price and on the same terms as in effect immediately prior to the closing of the Transaction (collectively, the “Investors”) entered into the Registration Rights andLock-Up Agreement, dated as of December 21, 2017 (the “Registration Rights andLock-Up Agreement”).

Pursuant to the terms of the Registration Rights andLock-Up Agreement, the Registrant is obligated to file, after we become eligible to use FormF-3 or its successor form, a shelf registration statement to register the resale by the Investors of our ordinary shares issuable in connection with the Transaction. The Registration Rights andLock-Up Agreement also provides the Investors with demand, “piggy-back” and FormF-3 registration rights, subject to certain minimum requirements and customary conditions. We have agreed to indemnify the Investors against certain liabilities, including liabilities under the Securities Act.

The Registrant is not currently eligible to file a registration statement on FormF-3. The Registrant currently expects to become eligible to file a registration statement on FormF-3 in 2019 and the Registrant currently expects to file a shelf registration statement during the course of 2019 in satisfaction of its obligations under the Registration Rights andLock-Up Agreement.

Notwithstanding theF-1 Registration Statement having become stale due to the age of the financial information included therein, certain of the securities that are registerable pursuant to the Registration Rights andLock-Up Agreement are entitled be sold bynon-affiliates of the Registrant pursuant to Rule 144 under the Securities Act, subject to the Registrant remaining current in its periodic reporting obligations under the Exchange Act.

Warrant Agreement

Between September 25, 2015 and October 9, 2015, Estre USA sold 37,000,000 units at a price of US$10.00 per unit in connection with its initial public offering. Each unit consists of one share of the Estre USA’s Class A common stock, US$0.0001 par value per share, andone-half of one warrant. Each warrant entitled the holder to purchase one share of Class A common stock of Estre USA at a price of US$11.50 per share. Each warrant would become exercisable starting on the later of 30 days after the completion of the Merger, or 12 months after the completion of the initial public offering of Estre USA. However, if Estre USA did not complete the Merger on or prior to the allotted period to complete the Merger, the warrants would expire at the end of such period.

Simultaneously with the closing of Estre USA’s initial public offering, Estre USA also issued an aggregate of 9,750,000 private placement warrants, each exercisable to purchase one share of Estre USA Class A Common Stock at US$11.50 per share, at a price of US$1.00 per warrant. Each private placement warrant was exercisable for one share of Estre USA’s Class A Common Stock. On December 13, 2017, in connection with the Transaction, the Sponsor agreed to cause the forfeiture and surrender of 3,748,600 private placement warrants, while we simultaneously issued 3,748,600 warrants to purchase our ordinary shares to ABCo-Invest, with each new warrant being exercisable for one ordinary share with an exercise price of US$11.50 per share.

All of the outstanding warrants are governed by the Warrant Agreement, dated as of September 21, 2015 and filed with the SEC on September 28, 2015 (as amended, the “Warrant Agreement”). Pursuant to the Transaction Agreement, Estre USA, we and the Continental Stock Transfer & Trust Company (“Continental”) entered into the Assignment, Assumption and Amendment Agreement, dated as of December 21, 2017 pursuant to which Estre USA assigned to us, and we assumed, all of Estre USA’s right, title and interest in and to the Warrant Agreement, dated as of September 21, 2015, by and between Estre USA and Continental, and the parties thereto agreed to certain amendments to reflect the fact that the warrants are, as a result of the Merger, exercisable for our ordinary shares.

Under the terms of the Warrant Agreement, the warrants will become exercisable starting on the date that is 30 days from the completion of the Merger, up until the earlier of: (i) the date that is five years from the completion of the Merger, (ii) our liquidation, or, (iii) in the case of the public warrants, the redemption date set forth in Warrant Agreement (triggered, at our option, in the event that the price of our ordinary shares is at least US$18.00 per share for 20 out of 30 trading days).

If we are unable to deliver ordinary shares to the warrant holder upon exercise of warrants during the exercise period, there will be no net cash settlement of such warrants and the warrants will expire worthless, unless they can be exercised on a cashless basis in the circumstances described in the Warrant Agreement.

Accordingly, pursuant to the Warrant Amendment, we are required to file a registration statement with the Commission, for the registration under the Securities Act of the ordinary shares issuable upon exercise of the outstanding warrants. We are required to use our best efforts to cause such registration statement to become effective and to maintain the effectiveness of such registration statement, and a current annual report relating thereto, until the expiry of the warrants in accordance with the terms of the Warrant Agreement. If such registration statement has not been declared effective by the sixtieth business day following completion of the Transaction, and during any period when there is not an effective registration statement covering the ordinary shares issuable upon exercise of the outstanding warrants, then the warrants are exercisable on a “cashless basis”, pursuant to the provisions of the Warrant Agreement, including, among other things, that, in order for the warrants to be exercised on a “cashless basis,” it is a requirement that the ordinary shares issuable upon exercise of the outstanding warrants would be freely tradable under U.S. securities laws.

In connection with the Transaction, the Registrant filed with the SEC a registration statement on FormF-4 under File Number333-220428 (the“F-4 Registration Statement”), including the related prospectus that was filed with the SEC on December 8, 2017, as supplemented by a supplement thereto file with the SEC on December 15, 2017 (as supplemented, the “Transaction Prospectus”). On January 24, 2018, the Registrant filed with the SEC a registration statement on FormF-1 under File Number333-222678, and filed apre-effective amendment thereto on February 23, 2018 and two post-effective amendments on July 12, 2018 and July 26, 2018 (the“F-1 Registration Statement”). TheF-1 Registration Statement was originally declared effective by the SEC but has since become stale due to the age of the financial information included therein and the Registrant currently expects to file a new registration statement on FormF-3 (the“F-3 Registration Statement”) in due course following the filing of this annual report on Form20-F. The Registrant currently anticipates that, upon the effectiveness of theF-3 Registration Statement, suchF-3 Registration Statement shall also constitute a post-effective amendment to theF-4 Registration Statement and the prospectus included within theF-3 Registration Statement shall cover the offer of the ordinary shares issuable upon exercise of the public warrants that was registered in theF-4 Registration Statement. Upon the exercise of the public warrants and the issuance of the ordinary shares, such ordinary shares will be freely tradable under U.S. securities laws.

Share Put Option Agreement

Angra held 8.21% of the Company’s shares prior to consummation of the Transaction. On the date of this annual report, Angra is no longer a minority shareholder of the Company.

In connection with the closing of the Transaction, certain people and entities who were shareholders of the Company immediately prior to closing of the Transaction entered into a Share Put Option Agreement with the Company. Pursuant to the Put Option Agreement, Angra had the option, at any time prior to January 31, 2018, to contribute its shares of the Company to the Registrant and receive ordinary shares, and thereby become a shareholder of the Registrant instead of being a shareholder of the Company. As of January 31, 2018, Angra had not exercised its Contribution Option to become a shareholder of the Registrant. Accordingly, Angra’s Contribution Option expired on that date.

In addition, in connection with the Transaction, Angra was granted a put option that permitted Angra to sell all, but not less than all, of its shares of the Company, which option was exercisable within six months from the closing of the Transaction. On March 6, 2018, Angra confirmed the exercise of its put option to sell all of its shares to the Company, and we are required to pay the exercise price of approximately R$40.3 million by September 6, 2018. Road Participações Ltda, a company through which the Registrant holds a portion of its interest in the Company, has granted security over 4.38% of the share capital of the Company as security for the obligation of the Company to pay the put option exercise price pursuant to the terms of the Put Option Agreement. As a result of the exercise of this put option, Angra is no longer a shareholder of the Company, and as of December 21, 2017, we recorded a liability at fair value in the amount of R$37.8 million.

D.	Exchange Controls and other Limitations Affecting Security Holders

Cayman Islands

There are no exchange control regulations or currency restrictions in the Cayman Islands.

Brazil

There are no restrictions on ownership of our shares by individual or legal entities domiciled outside Brazil. However, the right to convert dividend payments and proceeds from the sale of our shares into foreign currency and to remit such amounts abroad is subject to restrictions under foreign investment legislation, which generally require, among other things, that the relevant investment be registered with the Central Bank and/or the CVM, as the case may be.

Pursuant Law 4,131, dated as of September 3, 1962, as amended, Foreign investors must register their investments in our shares. There are currently two main available system, one under Resolution 3,844, dated as of March 23, 2010, as amended, known as foreign direct investment (investimento externo direto), or other system under Resolution 4,373, dated as of September 29, 2014 (which replaced Resolution 2,689, dated of January 26, 2000). Registration under Resolution 4,373 affords favorable tax treatment tonon-Brazilian investors who are not residents in a “tax haven” jurisdiction (i.e. countries that do not impose income tax or where the maximum income tax rate is lower than 17%), as defined by Brazilian tax laws.

Resolution 4,373 provides that foreign investors may invest in the financial and capital markets in Brazil, including by means of the issuance of depositary receipts in foreign markets in respect of shares of Brazilian issuers.

Under Annex I of Resolution 4,373, investments by investorsnon-resident or domiciled in Brazil shall be made in Brazil pursuant to the same instruments and operational modalities available to the investors resident or domiciled in Brazil. The definition ofnon-resident or domiciled investor includes individuals, legal entities, funds and other collective investment entities, resident, domiciled or headquartered abroad.

Pursuant to Annex I of Resolution 4,373, among the requirements applicable to the investment of anon-resident or domiciled investor in the Brazilian financial and capital market, such investor must:

•

appoint at least one representative in Brazil, which must be a financial institution or other institution authorized by the Central Bank to operate. The local representative appointed by the foreign investor shall be responsible for performing and keeping updated the registration of the investments made by the foreign investor with the Central Bank, as well as the registration of the foreign investor with the CVM;

•

obtain a registry as foreign investor with the CVM, through the representative appointed pursuant to item (i) above; and

•

establish or contract one or more custodians authorized by CVM to perform custody activities.

Securities and other financial assets held by foreign investors pursuant to Annex I Resolution 4,373 must be registered or maintained in deposit accounts or under the custody of an entity duly licensed by the Central Bank or the CVM, or be registered with clearing houses or other entities that provide services of registration, clearing and settlement duly licensed by the Central Bank or the CVM. In the case of Depositary Receipts (DRs), the record must be made by the Brazilian custodian entity on behalf of the foreign depositary institution.

Annex II of Resolution 4,373 of the National Monetary Council provides for the issuance of depositary receipts in foreign markets in respect of shares of Brazilian issuers. Our DR program was approved by the CVM prior to the issuance of the DRs.

For purposes of the mandatory registration with the Central Bank of foreign investments in the Brazilian financial and capital markets, Resolution 4,373 expressly provides that simultaneous foreign exchange transactions (i.e. without effective transfer of funds) shall be required in specific situations, including (i) conversion of credits held by foreign investors in Brazil into foreign investment in Brazilian companies in the financial and capital markets under Annex I of Resolution. 4,373; (ii) transfer of investments made in DRs under Annex II of Resolution. 4,373 into foreign direct investments (investimento externo direto) under Resolution 3,844; (iii) transfer of investments made in DRs under Annex II of Resolution. 4,373 into investments in the Brazilian financial and capital markets under Annex I of Resolution. 4,373; and (iv) transfer of investments in the Brazilian financial and capital markets under Annex I of Resolution. 4,373 into foreign direct investments (investimento externo direto) under Resolution 3,844.

147

In addition, Resolution 4,373 does not allow foreign investors to perform investments outside of organized markets, except as expressly authorized by CVM through specific regulation or according to the exceptions provided in CVM Rule 560/15. Pursuant to CVM Rule 560/15, the exceptions for investments outside of organized markets include subscription, stock bonus, initial purchase offers and the exercise of put options due to initial purchase offers, among others.

Foreign investors must be registered with the Brazilian Internal Revenue Service (Receita Federal do Brasil) pursuant to the Nominative Instruction 1,634, dated as of May 6, 2016 and Nominative Instruction 1,548, dated as of February 13, 2015. This registration process is undertaken by the foreign investor’s legal representative in Brazil.

The right to convert dividend payments and proceeds from the sale of our shares into foreign currency and to remit such amounts outside Brazil is subject to restrictions under foreign investment legislation which generally requires, among other things, that the relevant investment be registered with the Central Bank and/or the CVM, as the case may be. A foreign investor holder of shares may experience delays in obtaining a foreign investor registration, which may delay remittances outside Brazil and adversely affect the amount, in U.S. dollars, received by the foreign investor holder.

We have obtained a certificate of registration in the name of The Bank of New York, the depositary. Pursuant to this certificate, the custodian and the depositary are able to convert dividends and other distributions with respect to the shares represented by DRs into foreign currency and to remit the proceeds outside Brazil. If a holder exchanges DRs for shares, such holder must seek to register its investment directly with the Central Bank. Unless the holder has registered its investment with the Central Bank, such holder may not convert into foreign currency and remit outside Brazil the proceeds from the disposition of, or distributions with respect to, such shares. Such holder generally will be subject to less favorable Brazilian tax treatment than a holder of DRs.

As from 2005, the National Monetary Council enacted new regulations allowing, subject to certain procedures and specific regulatory provisions, the purchase and sale of foreign currency and the international transfer ofReais by a person or legal entity, without limitation of the amount involved, provided that the transaction is legal and has economic grounds (as evidenced by documents presented by the Brazilian person or legal entity to the financial institution executing the purchase and sale of foreign currency or the international transfer ofReais).

Under Brazilian law, whenever there is a serious imbalance in Brazil’s balance of payments or substantial reasons to foresee a serious imbalance, the Brazilian government may impose temporary restriction on the remittance of foreign currency abroad and on the conversion of Brazilian currency into foreign currencies. Such restrictions may hinder or prevent the custodian or holders who have exchanged DRs for underlying shares from converting distributions or the proceeds from any sale of such shares, as the case may be, into U.S. dollars and remitting such U.S. dollars abroad.

E.	Taxation

U.S. Federal Income Tax Considerations

The following discussion is a summary of U.S. federal income tax considerations generally applicable to the ownership and disposition of ordinary shares. This discussion is limited to holders who hold their ordinary shares as “capital assets” for U.S. federal income tax purposes (generally, property held for investment). This discussion does not address tax considerations that may be relevant to particular holders in light of their individual circumstances, including:

•

banks, financial institutions or insurance companies;

•

real estate investment trusts;

•

“controlled foreign corporations” or “passive foreign investment companies”;

•

dealers and brokers in stocks, securities or currencies;

•

traders in securities that use amark-to-market method of tax accounting;

•

tax-exempt entities;

•

certain former citizens or long-term residents of the United States;

•

persons that will hold our ordinary shares as part of a hedge, straddle, appreciated financial position, conversion or other “synthetic security” or integrated investment or risk reduction transaction for U.S. federal income tax purposes;

148

•

persons that will hold, directly, indirectly or constructively, 10% or more (by vote or value) of our equity or the equity of any of our subsidiaries; or

•

persons whose “functional currency” is not the U.S. dollar.

In addition, this discussion does not address the U.S. federal estate, gift or alternative minimum taxes, or any tax considerations arising under the net investment income tax, nor does it address any tax considerations arising under the laws of any state, local or foreign jurisdiction.

This discussion is based on provisions of the Code, administrative pronouncements, judicial decisions and final, temporary and proposed Treasury regulations, all as of the date hereof, and all of which are subject to change, possibly with a retroactive effect, or differing interpretations so as to result in U.S. federal income tax consequences different from those discussed below. There can be no assurance that the IRS or a court will not take a contrary position with respect to any U.S. federal income tax consequences described below.

For the purposes of this discussion, the term “U.S. Holder” means a beneficial owner of our ordinary shares that is, for U.S. federal income tax purposes:

•

an individual who is a citizen or resident of the United States;

•

a corporation (or other entity that is classified as a corporation for U.S. federal income tax purposes) that is created or organized in or under the laws of the United States, any State thereof or the District of Columbia;

•

an estate the income of which is subject to U.S. federal income tax regardless of its source; or

•

a trust (i) if a court within the United States is able to exercise primary supervision over the administration of the trust and one or more U.S. persons have the authority to control all substantial decisions of the trust, or (ii) that has a valid election in effect under applicable Treasury regulations to be treated as a U.S. person for U.S. federal income tax purposes.

For purposes of this discussion, a“Non-U.S. Holder” means a beneficial owner of our ordinary shares that is neither a U.S. Holder nor a partnership (or an entity or arrangement treated as a partnership) for U.S. federal income tax purposes.

If a partnership, or any entity treated as a partnership for U.S. federal income tax purposes, holds our common shares, the tax treatment of a partner in such partnership will generally depend on the status of the partner and the activities of the partnership. A partner in a partnership should consult its tax advisor regarding an investment in our ordinary shares.

Tax Residence for U.S. Federal Income Tax Purposes

As an exempted company incorporated under the laws of the Cayman Islands, we are generally classified as anon-U.S. entity (and, therefore, not a U.S. person) for U.S. federal income tax purposes. Section 7874 of the Code and the Treasury regulations promulgated thereunder, however, contain rules that may cause anon-U.S. corporation to be treated as a U.S. corporation for U.S. federal income tax purposes in certain cases. Whether the rules of section 7874 apply to cause us to be treated as U.S. corporation for U.S. federal income tax purposes depends on the application of complex statutory and regulatory rules to the steps of thePre-Closing Restructuring, the Merger, and certain related transactions (referred to herein as the “initial transactions”). There is limited guidance regarding the application of the rules of section 7874 to the initial transactions.

Under section 7874, a corporation created or organized outside the United States (i.e., anon-U.S. corporation) will nevertheless be treated as a U.S. corporation for U.S. federal income tax purposes (and, therefore, as a U.S. tax resident subject to U.S. federal income tax on its worldwide income) if (i) suchnon-U.S. corporation, directly or indirectly, acquires substantially all of the properties held directly or indirectly by a U.S. corporation (including through the acquisition of all of the outstanding shares of the U.S. corporation), (ii) thenon-U.S. corporation’s “expanded affiliated group” does not have “substantial business activities” in thenon-U.S. corporation’s country of organization or incorporation and, (iii) after the acquisition, the former shareholders of the acquired U.S. corporation hold at least 80% (by either vote or value) of the shares of thenon-U.S. acquiring corporation by reason of holding shares in the U.S. acquired corporation (taking into account the receipt of thenon-U.S. corporation’s shares in exchange for the U.S. corporation’s shares) as determined for purposes of section 7874 (this test is referred to as the “80% ownership test”). Where thenon-U.S. corporation is tax resident in a country that is different from the tax residence of an acquirednon-U.S. corporation, the 80% threshold in the 80% ownership test is replaced with 60 percent (such modified ownership test referred to as the “80/60% ownership test”).

149

For purposes of section 7874, the first two conditions described above were satisfied in connection with the initial transactions, because we acquired indirectly substantially all of the assets of Estre USA and neither we nor our “expanded affiliated group,” have “substantial business activities” in the Cayman Islands within the meaning of section 7874. Accordingly, whether the we are treated as U.S. corporation for U.S. federal income tax purposes depends on the application of the 80% ownership test referred to above. Because the Registrant is a tax resident in the Cayman Islands, and the Company is a tax resident in Brazil, the modified 80/60% ownership test applies to determine whether the initial transactions satisfy the ownership requirement.

Based on the terms of the initial transactions, the rules for determining share ownership under section 7874 (including the temporary section 7874 regulations), we expect that the initial transactions did not cause us to be treated as a U.S. corporation for U.S. federal income tax purposes. Nevertheless, the computation of whether the 80/60% ownership test has been met is subject to various complex adjustments for which there is limited guidance. In particular, under the temporary section 7874 regulations, certain adjustments are required that generally have the effect of increasing, for purposes of determining the section 7874 ownership percentage, the percentage of shares of a foreign acquiring corporation that is deemed owned by the former shareholders of an acquired U.S. corporation by reason of holding shares in such U.S. corporation. For example, certainpre-acquisition distributions made by an acquired U.S. corporation are “added back” to the value of the shares of thenon-U.S. corporation held by the former shareholders of the acquired U.S. corporation, which would have the effect of increasing the section 7874 ownership percentage. In addition, certain share issuances made by the acquiringnon-U.S. corporation, would generally be subtracted from the value of thenon-U.S. corporation’s shares, which also would have the effect of increasing the section 7874 ownership percentage. Moreover, the section 7874 ownership percentage takes into account the value of certain outstanding options of the acquiringnon-U.S. corporation owned by former shareholders of the acquired U.S. corporation, determined based on the excess of the value of the stock underlying such options at the time of the acquisition and their exercise price. Accordingly, the option rules may have the effect of increasing the section 7874 ownership percentage, depending on the value of our shares as of the closing of the Merger. Finally, Treasury regulations promulgated under section 7874 may disregard stock issued in connection with an acquisition of anon-U.S. corporation where the recipient of such stock satisfies apre-existing liability associated with the acquired non- U.S. corporation as part of the same overall plan or series of related transactions. As a result of the foregoing, the precise determination of the section 7874 ownership percentage is subject to significant uncertainties. Accordingly, there can be no assurance that the IRS will not assert that the 80/60% ownership test is met with respect to the initial transactions and that accordingly we should be treated as a U.S. corporation for U.S. federal income tax purposes or that such an assertion would not be sustained by a court.

Notwithstanding the foregoing, if we were treated as a U.S. corporation for U.S. federal income tax purposes, we could be liable for substantial U.S. federal income tax, dividends paid tonon-U.S. shareholders could be subject to U.S. withholding tax and certain other U.S. federal income tax consequences could apply to us that would adversely affect our tax and financial position.

The remainder of this discussion assumes that we are not and will not be treated as a U.S. corporation for U.S. federal income tax purposes. Investors are urged to consult their tax advisors on the tax consequences to them of the ownership and disposition of our shares if we are or were to be treated as a U.S. corporation for U.S. federal income tax purposes.

U.S. Holders

Distributions on Ordinary Shares

Subject to the discussion below under “ —Passive Foreign Investment Company Status,” the gross amount of any distribution on ordinary shares that is made out of our current or accumulated earnings and profits (as determined for U.S. federal income tax purposes) will generally be taxable to a U.S. Holder as ordinary dividend income on the date such distribution is actually or constructively received. To the extent that the amount of any such distribution exceeds our current or accumulated earnings and profits (as determined for U.S. federal income tax purposes), such amount will be treated first as a return of capital, and thereafter as capital gain. Because we do not intend to determine our earnings and profits on the basis of U.S. federal income tax principles, any distribution we pay will generally be reported as a dividend.

150

Dividends received on our ordinary shares will generally not be eligible for the dividends received deduction allowed to corporations under the Code. With respect to individuals and certain othernon-corporate U.S. Holders, dividends may constitute “qualified dividend income” that is subject to tax at the lower applicable capital gains rates provided that (1) the ordinary shares on which the dividends are paid are readily tradable on an established securities market in the United States or we are eligible for benefits of an approved comprehensive income tax treaty with the United States, (2) we are not a PFIC for either our taxable year in which the dividend was paid or the preceding taxable year, and (3) certain holding period requirements are met. Our ordinary shares are listed on the NASDAQ so they may qualify as readily tradable on an established securities market in the United States depending on the trading volume, although there can be no assurances in this regard. In addition, the rate reduction will not apply to dividends if the recipient of a dividend is obligated to make related payments with respect to the positions in substantially similar or related property. This disallowance applies even if the minimum holding period has been met. U.S. Holders should consult their tax advisors regarding the availability of the lower capital gains rate applicable to qualified dividend income for dividends paid with respect to the ordinary shares.

Sale, Exchange, Redemption or Other Taxable Disposition of Ordinary Shares

Subject to the discussion below under “ —Passive Foreign Investment Company Status,” a U.S. Holder will generally recognize gain or loss on any sale, exchange, redemption or other taxable disposition of ordinary shares in an amount equal to the difference between (i) the amount realized on the disposition and (ii) such U.S. Holder’s adjusted tax basis in such shares. Any gain or loss recognized by a U.S. Holder on a taxable disposition of ordinary shares will generally be capital gain or loss and will be long-term capital gain or loss if such holder’s holding period in such shares exceeds one year at the time of the disposition. Preferential tax rates may apply to long-term capital gains ofnon-corporate U.S. Holders (including individuals). The deductibility of capital losses is subject to limitations. Any gain or loss recognized by a U.S. Holder on the sale or exchange of ordinary shares will generally be treated as U.S. source gain or loss.

Passive Foreign Investment Company Status

The treatment of U.S. Holders of ordinary shares could be materially different from that described above, if we are treated as a PFIC for U.S. federal income tax purposes. If a U.S. Holder holds our ordinary shares in any year in which we are treated as a PFIC with respect to such U.S. Holder, adverse tax consequences to such U.S. Holder could result (including with respect to a dividend or other distribution from us or a disposition of our shares).

Anon-U.S. corporation will be a PFIC for U.S. federal income tax purposes for any taxable year in which, after the application of certain look-through rules either: (i) 75% or more of its gross income for such taxable year is passive income, or (ii) 50% or more of the total value of its assets (based on an average of the quarterly values of the assets during such year) is attributable to assets that produce passive income or are held for the production of passive income. Passive income generally includes dividends, interest, royalties, rents, annuities, net gains from the sale or exchange of property producing such income and net foreign currency gains. For this purpose, cash and assets readily convertible into cash are categorized as passive assets and the company’s unbooked intangibles are taken into account for determining the value of its assets. The determination of whether we are a PFIC is based upon the composition of our income, assets (including, among others, corporations in which we own at least a 25% interest), and the nature of our activities.

We must make a separate determination each year as to whether we are a PFIC. Based on a review of our gross income and assets, the manner in which we currently operate our business, the current market price of our shares, and the current interpretation of the PFIC provisions in the Code, we believe that we were not a PFIC for U.S. federal income tax purposes for the 2018 taxable year. However, the determination as to whether we are a PFIC for any taxable year is based on the application of complex U.S. federal income tax rules, which are subject to differing interpretations, depends upon the composition of a company’s income and assets and the market value of its assets from time to time, and is not made until after the end of a taxable year. Consequently, there can be no assurance that we will not be considered a PFIC for the current taxable year or any subsequent taxable year. U.S. Holders should consult their tax advisors regarding the U.S. federal income tax consequences to them as a result of the PFIC rules in the event that we are treated as a PFIC.

151

Foreign Asset Reporting

Certain U.S. Holders are required to report information relating to an interest in our common shares, subject to certain exceptions (including an exception for shares held in accounts maintained by certain financial institutions), by filing IRS Form 8938, Statement of Specified Foreign Financial Assets, with their tax return for each year in which they hold an interest in our common shares. U.S. Holders should consult their tax advisors regarding foreign asset reporting requirements relating to their ownership of our common shares.

Non-U.S. Holders

In general, aNon-U.S. Holder of our ordinary shares will not be subject to U.S. federal income tax or, subject to the discussion below under “—Information Reporting and Backup Withholding” and above under “Tax Residence for U.S. Federal Income Tax Purposes,” U.S. federal withholding tax on any dividends on our ordinary shares or gain recognized on a sale or other disposition of our ordinary shares (including, any distribution to the extent it exceeds the adjusted basis in theNon-U.S. Holder’s ordinary shares) unless:

the dividend or gain is effectively connected with theNon-U.S. Holder’s conduct of a trade or business in the United States, and if required by an applicable tax treaty, is attributable to a permanent establishment maintained by theNon-U.S. Holder in the United States; or

in the case of gain only, theNon-U.S. Holder is a nonresident alien individual present in the United States for 183 days or more during the taxable year of the sale or disposition, and certain other requirements are met.

ANon-U.S. Holder that is a corporation also may be subject to a branch profits tax at a rate of 30% (or such lower rate specified by an applicable tax treaty) on its effectively connected earnings and profits for the taxable year, as adjusted for certain items.Non-U.S. Holders should consult their tax advisors regarding any applicable tax treaties that may provide for different rules. In addition,Non-U.S. Holders should consult their tax advisors regarding the particular U.S. federal income and other tax consequences if we were treated as U.S. corporation for U.S. federal income tax purposes pursuant to section 7874.

Information Reporting and Backup Withholding

Dividends received with respect to our ordinary shares and proceeds from the sale, exchange or other disposition of our ordinary shares may be subject to information reporting to the IRS and possible U.S. backup withholding at the applicable rate. Backup withholding will not apply, however, to a holder who furnishes a correct taxpayer identification number and makes other required certifications, or who is otherwise exempt from backup withholding (such as a corporation) and establishes such exempt status.

Backup withholding is not an additional tax. Amounts withheld as backup withholding may be credited against the holder’s U.S. federal income tax liability, and a holder may obtain a refund of any excess amounts withheld under the backup withholding rules by timely filing the appropriate claim for a refund with the IRS and furnishing any required information. Holders should consult their tax advisors regarding the application of the U.S. information reporting and backup withholding rules.

Cayman Islands Tax Considerations

The following is a discussion on certain Cayman Islands income tax consequences of an investment in the securities of the Registrant. The discussion is a general summary of present law, which is subject to prospective and retroactive change. It is not intended as tax advice, does not consider any investor’s particular circumstances, and does not consider tax consequences other than those arising under Cayman Islands law.

Under Existing Cayman Islands Laws:

Payments of dividends and capital in respect of the Registrant’s securities will not be subject to taxation in the Cayman Islands and no withholding will be required on the payment of a dividend or capital to any holder of the securities nor will gains derived from the disposal of the securities be subject to Cayman Islands income or corporation tax. The Cayman Islands currently have no income, corporation or capital gains tax and no estate duty, inheritance tax or gift tax.

No stamp duty was, or will be, payable in respect of the issue of the warrants. An instrument of transfer in respect of a warrant is stampable if executed in or brought into the Cayman Islands.

152

No stamp duty was, or will be, payable in respect of the issue of the Registrant’s ordinary shares or on an instrument of transfer in respect of such shares.

The Registrant has been incorporated under the laws of the Cayman Islands as an exempted company with limited liability and, as such, has obtained an undertaking from the Financial Secretary of the Cayman Islands in the following form:

The Tax Concessions Law

(2018 Revision)

Undertaking as to Tax Concessions

In accordance with the provision of Section 6 of The Tax Concessions Law (2018 Revision), the Financial Secretary undertakes with the Registrant:

1. That no law which is hereafter enacted in the Islands imposing any tax to be levied on profits, income, gains or appreciations shall apply to the Registrant or its operations; and

2. In addition, that no tax to be levied on profits, income, gains or appreciations or which is in the nature of estate duty or inheritance tax shall be payable:

2.1 On or in respect of the shares, debentures or other obligations of the Registrant; or

2.2 by way of the withholding in whole or part, of any relevant payment as defined in Section 6(3) of the Tax Concessions Law (2018 Revision).

These concessions shall be for a period of twenty years from September 19, 2017.

ITEM 11.

QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

Market Risk

We are exposed to various types of market risk in the normal course of business, including the impact of interest rate changes, changes in the prices of fuel and credit risk in relation to the potential of default by our customers in their payment of billed amounts, which is particularly heightened in an adverse macroeconomic scenario. We do not enter into derivatives for risk management purposes. We do not have any financings, revenues, or costs and expenses denominated in currencies other than reais. Therefore, while we are generally impacted by macroeconomic factors in Brazil, we are not directly impacted by currency exchange fluctuations. Uncertainties that are eithernon-financial or not quantifiable, such as political, economic, tax or other regulatory risks, are not included in the following assessment of our market risks.

Credit Risk

Credit risk refers to the risk of a counterparty not performing on its contractual obligations to us, which would lead us to incur financial losses. Customer credit risk is managed by each business segment, subject to our procedures, policies and controls. In an adverse macroeconomic scenario as has been ongoing in Brazil since 2014, the risk of customer default is heightened. Specifically with respect to our public entity customers, periods of economic slowdown tend to exert greater budgetary pressures on municipalities as government revenues decrease. In accordance with industry practice in Brazil, we seek to reduce credit risk by issuing invoices only after formal approval is given by the customer.

For information on our trade accounts receivable policy, see “Item 5.A. Operating and Financial Review and ProspectsHow We Generate Revenue—Summary of Our Trade Accounts Receivable Policy”, and for more information on our policy relating to allowances for doubtful accounts, see “Item 5.A. Operating and Financial Review and Prospects—Operating Results—How We Generate Revenue—Allowance for Doubtful Accounts.”

Interest Rate Risk

Interest rate risk is the risk that the fair value of future cash flows of a financial instrument fluctuates due to changes in market interest rates. Our exposure to the risk of changes in market interest rates refers primarily to long-term obligations subject to variable interest rates. We are exposed to interest rate risk in connection with certain of our investments, accounts payable for acquisition of investments, loans and financing and, most significantly, our debentures and related debt acknowledgment instrument. For additional information, see “Item 3.D. Key Information—Risk Factors—Risks Related to Brazil—We are exposed to variations in interest rates, which may have adverse effects on us.”

We are exposed to variations in interest rates, which may have adverse effects on us.

154

We conducted a sensitivity analysis of the interest rate risks to which our financial instruments are exposed as of December 31, 2018. For this analysis, we adopted as a probable scenario for the future interest rates according to quotations obtained from B3 S.A. of 6.72% for CDI interest rates and 6.98% for TJLP interest rates. When estimating an increase or decrease in current interest rates by 25% and 50%, finance income (costs) would be impacted as follows (without considering the impact of the Transaction on our results of operations and financial position):

Fuel Price Risk

We are subject to risks associated with diesel fuel prices in relation to our fleet of collection and transfer trucks as part of our Collection & Cleaning Services segment. However, we do not have any hedging or derivative instruments in place to mitigate these risks.

We purchase fuel from a number of distributors in Brazil, principally from Ipiranga Produtos de Petróleo S.A., pursuant to one year renewable contracts providing us with generally more attractive pricing than we could otherwise obtain in the open market.

Our diesel fuel contract with Ipiranga provides for the purchase and delivery of a minimum of 33.6 million liters of diesel fuel per year at a fixed price, with prices being adjusted on an yearly basis. Fuel delivery takes place upon request by us.

Liquidity Risk

Liquidity risk, in the context of our operations, can be defined as the possibility of us failing to meet our obligations in connection with our principal financial liabilities due to insufficient liquid funds, especially with respect to the balance of interest and principal on our loans and financings, debentures, tax liabilities, trade accounts receivable and other accounts payable. In order to manage cash liquidity, we analyze various variables and scenarios regarding future payables or receivables, and our treasury department monitors our liquidity and associated risks daily. When managing our cash flow, we focus on: (i) preserving the value of invested capital, (ii) keeping a liquidity level appropriate to the commitments we have assumed and (iii) obtaining an appropriate return of the investment portfolio.

As of December 31, 2018, we recorded negative working capital (represented by total current assets minus total current liabilities) of R$1,289.8 million and a capital deficiency of R$1,149.2 million, and as of December 31, 2017, we recorded negative working capital of R$293.4 million and a capital deficiency of R$455.9 million. Our Debt Restructuring concluded in 2017 has resulted in substantial debt reduction at a discount to our outstanding principal amount and a material increase in cash on hand in our balance sheet. However, the Debt Restructuring was not effective in fully reducing our vulnerability going forward. For example, on March 6, 2018, Angra confirmed the exercise of its put option to sell all of its shares of the Company to the Registrant at the aggregate put option exercise price of approximately R$40.3 million plus accrued interest. We were required to pay the exercise price within six months from the date on which the transfer of shares from Angra to the Company occurs, however, as of the date of this annual report, we have not yet made any payments to Angra due to a weak cash position, and the terms of payment to Angra are still being negotiated. This payment will further negatively impact our cash position and, thereby, adversely affect us. See “Item 10.C. Additional Information—Material Contracts—Share Put Option Agreement.”

155

Our ability to continue as a going concern is dependent on various factors, and there are no assurances that we will be successful in our efforts to maintain a sufficient cash balance, report profitable operations in the future or pay our debts as they fall due, any of which could impact our ability to continue as a going concern. Any such inability to continue as a going concern may result in our shareholders losing their entire investment. For further information, see “Item 3.D. Key Information—Risk Factors—Risks Related to Our Business—Our auditors have issued a “going concern” audit opinion, and our ability to continue as a going concern is dependent on our improved liquidity position.”

PART II

ITEM 13.

DEFAULTS, DIVIDEND ARREARAGES AND DELINQUENCIES

Prior to the Transaction, we were in noncompliance with certain of our obligations under the instruments governing our existing debentures, which noncompliance included failure to pay principal and interest as required as well as failure to meet the financial covenant ratios set forth therein, which may have constituted events of default under such instruments. In July 2017, we successfully obtained waivers with respect to such noncompliance.

Pursuant to the Debt Restructuring, at the closing of the Transaction, we paid US$110.6 million to our Creditors and a discount of 25% of the amount paid was granted by the debenture holders, as more fully described in“Item 5.A. Operating and Financial Review and Prospects—Operating Results—Key Factors Affecting Our Results of Operations—Restructuring Plan.” These actions have resulted in the discharge of any potential defaults or events of defaults existing under our current financing instruments at the time.

However, the terms of the instruments that resulted from the Debt Restructuring require, among other things, that, as of December 31, 2018, the Company’s consolidated net debt to EBITDA ratio must be 4.0x or less. In addition, the Debt Instruments also contain a covenant that requires the Company’s debt service coverage ratio to be at least 1.2x. The Company’s financial statements demonstrated that our consolidated net debt to EBITDA was 7.9x, significantly higher as of December 31, 2018 than the 4.0x required by the relevant covenant. In addition, our debt service coverage ratio was negative 15.6x as of December 31, 2018, lower than the 1.2x ratio required by the relevant covenant.

In addition, the terms of such instruments required that, by December 31, 2018 the Company register certain liens on certain real estate relating to operational landfills with the appropriate governmental agencies and to provide certain documents listed in the annexes to the Debentures. Whilst the Company is taking appropriate steps to comply with its obligation and to attempt to register the relevant liens, the Company was unable to comply with such covenants by December 31, 2018.

Therefore, the Company is in default of its obligations towards its debenture holders. These defaults entitle the banks that hold the debentures to accelerate the debt obligations and declare that all amounts owed under such instruments are immediately due and payable.

As described in “Item 5A. Operating and Financial Review and Prospects—Operating Results—Liquidity Constraints and Breach of Financial Covenants,” our debentures are secured by collateral consisting of a lien on all real estate relating to the Company’s operational landfills, a lien on all material subsidiaries controlled, directly or indirectly, by us and a fiduciary assignment of the remaining balance originated from the foreclosure of liens granted in relation to such debt. In addition, there is further security by a fiduciary assignment of certain real estate owned by us and a fiduciary assignment lien on all of the common shares of Estre (except for 4.38% secured for the benefit of Angra), the Company’s main operating subsidiary. Moreover, the debentures are also guaranteed by all material subsidiaries controlled, directly or indirectly, by us. The breach of the obligations our obligations entitles the holders of the debentures to enforce against any collateral securing the such securities.

However, since the Company was unable to obtain a waiver from the banks that hold the Debt Instruments by December 31, 2018 in relation to the defaults described above, pursuant to IFRS accounting rules, the Company reclassified the total outstanding amount of the Debt Instruments as short-term obligations in the Company’s consolidated financial statements as of December 31, 2018. The restructuring of the Company’s debt is also expected to cover other debts such as amounts owned by the Company under theNon-Compete Agreement and Angra Put Option that the Company entered into with its former shareholders as part of the 2017 business combination transaction which resulted in the listing of the Company’s shares on the NASDAQ.

CONTROLS AND PROCEDURES

A.	Disclosure Controls and Procedures

Under the supervision and with the participation of our management, including our Chief Executive Officer and our Interim Chief Financial Officer, we carried out an evaluation of the effectiveness of our disclosure controls and procedures, which is defined in Rules13a-15(e) of the Exchange Act, as of December 31, 2018. In this context, “disclosure controls and procedures” means controls and procedures of a company that are designed to ensure that information required to be disclosed 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, and that it is accumulated and communicated to management, including its principal executive and principal financial officers, as appropriate to allow timely decisions regarding required disclosure. Based upon our evaluation, our management concluded that our disclosure controls and procedures as of December 31, 2018 were ineffective in view of the material weakness in internal control over financial reporting as described below.

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 such term is defined in Exchange ActRule 13a-15(f). Under the supervision and with the participation of our management, including our Chief Executive Officer and Interim Chief Financial Officer, we conducted an evaluation of the effectiveness of our internal control over financial reporting as of December 31, 2018 based on the criteria set forth inInternal Control-Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO 2013). Based on our evaluation under the criteria set forth inInternal Control—Integrated Framework, our management concluded that our internal control over financial reporting were not effective as of December 31, 2018 as a result of the material weaknesses discussed below.

The material weaknesses in internal control over financial reporting identified by our management, including certain material weaknesses previously identified as of December 31, 2017 that remain in existence, are as follows:

•

ineffective centralization and implementation of policies, procedures and criteria with respect to accounting for certain revenue and related accounts receivable, including in relation to (i) revenue/accounts receivables and related allowances, costs/expenses/accounts payables, property, plant and equipment, related parties, contingencies, provision for retirement of landfills, and (ii) there being no procedures or guidance for personnel, systems and controls that keep pace with the organizational structure;

•

lack of formalized controls in order to monitor if Company’s employees have the necessary trainings to deal with the complexity of the Company’s business and an individual formalized assessment of performance to all employees;

•

lack of a robust control environment for the revenue/ accounts receivable process, where the Company does not have mandatory formalized controls for: (i) formal analysis over applied contract pricing and profitability; (ii) formal review of billed invoices and monitoring of ongoing contracts; (iii) monitoring controls on subsidiaries regarding accounts receivables and revenue recognition processes;

•

inefficiency in controls for provisions related to contingencies (government taxes and third contracts) where the probability of loss could not be updated reflecting the actual risk defined by our legal team and external lawyers;

•

continued use of manual processes as a result of the delayed implementation of our enterprise resource planning (ERP) system that could result in delays and errors in our financial closing and reporting process;

•

shortcomings in the implementation and maintenance of effective IT general controls;

•

defective communication processes and procedures hampering the efficient exchange of information within our organization, particularly among our legal, financial and accounting departments;

•

inefficiency of our procurement process that leads the business units to perform purchases of goods and services using the emergency process where the level of controls is substantially lower and could impact negatively our costs and compliance controls; and

•

lack of policy or procedures on how to perform the impairment analysis, which caused a high volume of findings during the audit process in the calculation prepared by management with regards concepts and routines to update the calculation based on the most recent financial position, associated with the absence of controls to guarantee that figures to be used in the calculation are correctly captured or calculation itself reflects the correct concepts.

158

Remediation Plan

As disclosed in Item 15 of our annual report on Form20-F for the year ended December 31, 2017, we identified a number of material weaknesses in internal control over financial reporting and we provided disclosure on our management’s remediation plan to address such material weaknesses. We are in the process of implementing the aforementioned remediation plan and during 2018, our management undertook a broad range of remedial actions in order to implement certain changes in our internal control over financial reporting to address previously identified material weaknesses.

In addition, in connection with our management’s evaluation of our internal control over financial reporting as of December 31, 2018, our management updated its remediation plan to address the material weaknesses in internal control over financial reporting.

We have been undergoing a comprehensive financial and corporate restructuring over the past several years pursuant to which we have reviewed and rationalized our cost structure, pricing, compliance and controls, planning processes, information technology and use of data. This restructuring effort has yielded several tangible benefits through focus on the following initiatives, among others: (i) the comprehensive redesign of our management information systems, including migration to SAP and implementation of CRM Oracle solutions and pricing systems, with the effect of improving efficiency of pricing and internal controls; (ii) the sale of certain assets that negatively impacted our margins and did not align with our strategic vision, (iii) collection of overdue accounts and successful implementation of price adjustments on certain large contracts with our municipal customers and (iv) the reorganization of our senior management team. Notwithstanding our substantial progress, we have identified significant areas for further improvement, as evidenced by the weaknesses identified above, as we continue to implement our restructuring initiatives with a continued focus on improved internal controls.

Our remediation plan consists of the improvement areas, steps and actions set forth below. As described under “—Changes in Internal Control Over Financial Reporting” below, we currently expect to have all action plans fully implemented by the end of 2019:

•

the replacement of all members of the senior management team at Soma as a result of our internal review process led by the special committee of our board of directors;

•

making certain adjustments to our compliance infrastructure to strengthen the independence of our compliance function and eliminate opportunities to override controls across our organization, including at Soma and of all our other subsidiaries and our joint ventures;

•

obtaining and thereafter maintaining international certification ISO 37001 (anti-bribery system) for Estre and Cavo, which confirmed improvements in our system of integrity and compliance as well as validation of its suitability with industry best practices. In addition the adherence and effectiveness of the integrity program were validated by independent external consulting firm;

•

expanding our Compliance and Integrity program to all our subsidiaries and joint ventures, with the following controls: due diligence procedures on 100% of suppliers, validation of goods delivered and services provided, adequate segregation of reviews and approvals for purchases and its payments, whistleblower channel, training employees regarding Code of Ethics & Conduct and Anti-Corruption Policy and Compliance & Integrity programs;

•

maintaining and improving our compliance control environment at Soma, including the following controls and monitoring activities: Code of Ethics and conduct, anti-corruption, anti-bribery, relationships with public bodies and agents, due diligence over suppliers policies and related disclosure and training, exclusive whistleblower channel, analysis of risk hiring, confirmation of services provided and goods delivered, monitoring of payments performed directly in the finance module, monitoring of sequential invoices;

•

holding an annual compliance day event to confirm and disclose to all stakeholders Estre’s senior management commitment to the highest and most stringent standards of compliance, especially with respect to the Brazilian anti-corruption law and the US Foreign Corruption Practices Act;

•

making certain adjustments to our internal audit team, increasing the number of employees in the team to strengthen the Company’s ability to continuously evaluate its internal control environment and procedures and identify any weaknesses or misconduct and generate corrective actions in its early stages;

•

implementation of a new policy on related party transactions that will better enable us to trace and identify related party transactions in a more systematic way;

•

enhancing policies and procedures to verify that our comprehensive compliance policies and procedures are fully implemented at all of our subsidiaries and joint ventures;

159

•

further upgrading our ERP business process management software, in order to better manage our business and automate many back office functions with the goal of improving our internal control over financial reporting and streamlining monthly, quarterly andyear-end closings. The full system migration and full use of the new tools is expected to be completed in 2019;

•

enhancing and continuing to improve the vendor master data, due diligence, know your client procedures, procurement and payment procedures and associated controls;

•

implementing a workflow tool, under the direction of our new CFO, allowing the controlled exchange of information to facilitate timely and effective communication amongst the legal, financial and accounting departments and prompt registration of all transactions; and

•

making certain adjustments to improve the security in some of our IT procedures such as the periodic review of login profiles and their access to certain information on the system and the closer management of users with privileged profiles.

C.	Attestation Report of the Registered Public Accounting Firm

Pursuant to applicable SEC rules, this annual report does not include an attestation report by our independent registered public accounting firm. We will only be required to include this report once we become a large accelerated filer or otherwise cease to be an emerging growth company.

D.	Changes in Internal Control Over Financial Reporting

We are in the process of implementing management’s remediation plan for the remediation of the material weaknesses described in Item 15 of our annual report on Form20-F for the year ended December 31, 2017. During 2018, our management undertook a broad range of remedial actions in order to implement certain changes in our internal control over financial reporting to address previously identified material weaknesses.

The changes in internal control over financial reporting that were made during 2018 in furtherance of our management’s remediation plan include, among others:

•

increased the number of employees in the internal audit team; and

•

upgrading our ERP business process management software to better manage our business and automate many back office functions with the goal of improving our internal control over financial reporting and streamlining monthly, quarterly andyear-end closings for some of our operations.

Except as disclosed above, there were no changes in our internal control over financial reporting that occurred during the period covered by this annual report on Form20-F that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

CORPORATE GOVERNANCE

The Registrant is a “foreign private issuer” (as such term is defined in Rule3b-4 under the Exchange Act) incorporated in the Cayman Islands, and its corporate governance practices are governed by applicable Cayman Islands law. In addition, because our ordinary shares are listed on the NASDAQ Capital Market, we are subject to the NASDAQ’s corporate governance requirements.

NASDAQ-listed companies that are foreign private issuers are permitted to follow home country practice in lieu of the corporate governance provisions specified by NASDAQ with limited exceptions.

With effect from the date of this annual report, we follow home country practice that does not require us to obtain shareholder approval for issuing additional securities exceeding 20% of our outstanding ordinary shares. NASDAQ Stock Market Rule 5635(d) requires each issuer to obtain shareholder approval for the issuance of securities in connection with a transaction other than a public offering involving certain issuances of ordinary shares in amounts equaling 20% or more of such issuer’s ordinary shares there outstanding. Maples, our Cayman Islands counsel, has provided a letter to NASDAQ certifying that under the Companies Law, we are not required to obtain shareholders’ approval prior to any issuance of our ordinary shares. The foregoing is subject to our memorandum and articles of association, as amended and restated from time to time.

In addition, in the future, we may determine that the home country rules in the Cayman Islands position us to operate more efficiently than equivalent NASDAQ rules. Until we determine otherwise, except as referred to above, we are bound by all of the same NASDAQ corporate governance rules that a U.S. domestic company listed on the NASDAQ Capital Market would be required to follow.

Report of Independent Registered Public Accounting Firm

To the Shareholders and the Board of Directors of Estre Ambiental, Inc.

Opinion on the Financial Statements

We have audited the accompanying consolidated statement of financial position of Estre Ambiental, Inc. (the “Company”) as of December 31, 2018 and 2017, the related consolidated statement of profit or loss, other comprehensive (loss) income, changes in equity, and cash flows, for each of the three years in the period ended December 31, 2018, 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 of December 31, 2018, and the results of its operations and its cash flows for the year ended December 31, 2018 in conformity with International Financial Reporting Standards (IFRS) as issued by the International Accounting Standards Board - IASB.

The Company’s Ability to Continue as a Going Concern

The accompanying consolidated financial statements have been prepared assuming that the Company will continue as a going concern. As discussed in Note 1.2 to the consolidated financial statements, the Company has suffered recurring losses from operations, is in the process of renegotiating debt obligations, has a net capital deficiency and has stated that substantial doubt exists about the Company’s ability to continue as a going concern. Management’s evaluation of events and conditions and their plans in regard to these matters are also described in Note 1.2. The consolidated financial statements do not include any adjustments that might result from the outcome of this uncertainty.

Basis for Opinion

These financial statements are the responsibility of the Company’s management. Our responsibility is to express an opinion on the Company’s financial statements based on our audits. We are a public accounting firm registered with the 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 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 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 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 financial statements. We believe that our audits provide a reasonable basis for our opinion.

/s/ ERNST & YOUNG Auditores Independentes S.S.

We have served as the Company’s auditor since 2010.

General information

Estre Ambiental, Inc. is a holding company incorporated under the laws of the Cayman Islands on September 11, 2017. Estre Ambiental, Inc. became the holding company of Estre Ambiental S.A. (hereafter referred to as “Estre Brazil”) through the completion of the transaction explained below.

Estre Ambiental, Inc.’s registered office is located at Av. Brigadeiro Faria Lima, 4.509 – 8th floor, Itaim Bibi, in the city and state of São Paulo, Brazil.

On August 16, 2017, Estre Brazil, a waste management company with operations in Brazil, and Estre USA, Inc., formerly Boulevard Acquisition Corp II, (“Estre USA”), a company sponsored by an affiliate of Avenue Capital Group, jointly announced that they had entered into a definitive agreement (the “Transaction”) pursuant to which a Cayman Islands holding company, Estre Ambiental, Inc., would be incorporated and substantially all of the shareholders of Estre Brazil would exchange their shares of Estre Brazil for shares of Estre Ambiental, Inc. and as a result Estre Brazil would become a subsidiary of Estre Ambiental, Inc. In addition, the shareholders of Estre USA would be granted an exchange offer to exchange their shares and warrants in Estre USA for shares and warrants in Estre Ambiental, Inc.

The Transaction was completed on December 21, 2017 and as a result, Estre Ambiental, Inc. became a publicly listed company subject to rules and regulations of the United States Securities and Exchange Commission. Estre Ambiental, Inc.’s ordinary shares and warrants are traded on the NASDAQ stock exchange.

Also on December 21, 2017, Estre Ambiental, Inc. issued 15,438,000 ordinary shares and 3,748,600 warrants to purchase Estre Ambiental, Inc. ordinary shares at US$11.50 per share to certain institutional investors pursuant to a private investment in public equity (the “PIPE Investment”).

As a result of the above, Estre Ambiental, Inc. received a total of US$139,900 thousand in cash, out of which US$110,600 thousand (or R$365 million) was contributed to Estre Brazil as a capital contribution which was used to repay certain of its indebtedness pursuant to a simultaneous debt restructuring agreement entered into with its creditors, granting a reduction corresponding to 25% of the amount prepaid. The terms of Estre Brazil’s existing debentures and related debt acknowledgment instrument were consequently amended and restated (for more details, see Notes 21.1 and 14).

Business perspectives

Following a period of rapid expansion and growth through organic business generation as well as acquisitions between 2011 and 2013, in 2014, the Company began recalibrating its strategic focus on the following initiatives, among others; (i) the comprehensive redesign of our management information systems, including migration to SAP; (ii) the sale of certain assets that negatively impacted our margins and did not align with our current strategy, (iii) collection of overdue accounts and implementation of price adjustments on certain large contracts with our municipal customers and (iv) the reduction of corporate headcount.

As described above, the Company emerged from 2017 as a NASDAQ listed public company, with a lower leveraged balance sheet and a stronger governance, led by an independent board of directors.

Business perspectives(Continued)

A significant portion of the Company’s revenue is derived from municipalities whose financial health have been negatively impacted by very weak economic performance, with Brazilian GDP contracting by 3.3% in 2016 and with 1.1% and 1% increase in 2018 and 2017, respectively. As the outlook for the economy evolves, so does the Company’s ability to collect on time payments from municipalities.

The Company’s customer base includes a mix of customers operating in both the private and public sectors. Although the Company has a diversified base across our four business segments, our top ten customers accounted for 69.4% of our total net revenues in 2018 (74.0% of our total net revenues in 2017).

In addition, the Company relied over the past years significantly on certain municipal customers in the Collection & Cleaning segment as a source of revenues, including the municipalities of São Paulo and Curitiba. Together, the contracts with those two municipalities represented 39.9% and 41.7% of total net revenues from services during 2018 and 2017, respectively.

The contract with the municipality of São Paulo for urban cleaning and street sweeping services, which the Company services through its subsidiary Soma, represented approximately 25.5% of our revenues in 2018 (29.1% of our revenues in 2017).

We have been servicing the São Paulo contract through Soma since 2011. This contract expired, and we are currently providing urban cleaning services to the city of São Paulo pursuant to a temporary contract. The temporary contract was first entered into on December 15, 2017 and expired in June 2018. On June 12, 2018, we further extended the temporary contract until the end of 2018. In December 2018, we signed a new extension of the contract which is set to expire in June 2019 and, on May 2, 2019, we were informed that our emergency contract with the municipality of São Paulo will be terminated on June 1, 2019, at which point we will no longer provide services in São Paulo. However, the extended temporary contract which was executed in June 2018 introduced certain significant changes to the expired contractual arrangement and first temporary contract. Most significantly, under the extended temporary contract, the city of São Paulo has been divided into six separate parcels for urban cleaning, whereas under the prior contract the city had been divided into two parcels only. We, through Soma, were awarded only two parcels under the extended temporary contract, which reflects a significant decrease of our service area, since we previously serviced one of the only two parcels. As a result of these changes, the monthly revenue under the extended temporary contract decreased by 37.7%.

Business perspectives(Continued)

The contract with the municipality of Curitiba for waste collection, urban cleaning and street cleaning represented approximately 12.0% of the Company’s revenues in 2018 (12.5% in 2017). In October 2018, the Company won the competitive bidding process for the Curitiba collections and cleaning contract and signed a five-year contract on January 3, 2019 with a maximum value of R$844.8 million (a reduction in price of approximately 14.1% compared with the previous contract).

Considering the significance of these two contracts in terms of revenues, and the fact that the contract with the municipality of São Paulo was not renewed, the Company’s future revenues will materially decrease.

As consequence of these changes the company has several significant obligations arising during 2019 that require funding through liquidity, primarily relating to (a) the payments required as a consequence of contracts termination (for example, the contract with the municipality of São Paulo for cleaning services, which is expect to terminate in June 2019) and (b) capital expenditures (e.g., new trucks and equipment) required in connection with contract renewals, such as the investment obligations arising under the contract with the municipality of Curitiba for cleaning services, which was renewed on January 3, 2019 for an additional five year period. Management is working on the negotiations for the sale of some assets, in order to support these discontinuation costs and new fleet investments. Any asset sale will require debt holders’ approval.

The Company’s 2019 budget which was approved by the Board of the Directors reflects the impact of the above in addition to certain strategic decisions in relation to Company’s ongoing business, which resulted in the recognition of impairment charges in 2018 as further explained in Note 12.

As a result of the expected cash shortfalls for 2019 and the fact that the Company breached its loans financial covenants as of and for the year ended on December 31, 2018, the Company and its Board of Directors are currently negotiating with the debt holders the terms of the current debt agreements. The Company engaged a third party financial specialist as well as outside legal counsel to advise in the negotiation. The Company expects to conclude the debt restructuring process during 2019.

There can be no assurance that the debt restructuring process will be successful or that the Company will be able to generate sufficient liquidity in order to fully address the liquidity concerns. The Company´s inability to significantly improve its liquidity position and comply with its financial covenants and other payment obligations could have a material adverse effect and result in a judicial reorganization process, which may result in the shareholders losing their entire investment.

Accordingly Management concluded that substantial doubt exists with respect to our ability to continue as a going concern through one year after the issuance of the accompanying consolidated financial statements.

On January 9, 2016, Estre Brazil entered into an agency agreement with USA Global Market S.A.S, or USA Global, for the sale of Estre Brazil’s 51% interest in CGR Doña Juana S.A ESP, or Doña Juana, based in Colombia. Pursuant to the terms of the agreement, USA Global, Estre Brazil’s partner andco-investor in Doña Juana, agreed to seek a compatible buyer for Estre Brazil’s interest in Doña Juana and, in the meantime, advanced payments to Estre Brazil for the sale. The initial term of this agency agreement was 18 months, subsequently extended for a further 12 months, during which time Estre Brazil received 59.6% of the purchase price for Doña Juana of R$6,207 from USA Global in four installments over the course of 2016 and 2017.

Upon signing the agency agreement Estre Brazil classified the investment in Doña Juana as an asset held for sale, pursuant to IFRS 5,Non-current Assets Held for Sale and Discontinued Operations (‘‘IFRS 5’’) at its carrying amount which was lower than its fair value. After the investment in Doña Juana was classified as held for sale, Estre Brazil ceased to apply the equity method in accordance with IAS 28.

In February 2018, Estre Brazil signed an amendment to the agency agreement postponing some of USA Global’s obligations, such as (i) extending the date that the final installment would be paid to May, 26, 2018, noting that such payment, as of December 31, 2018, remains outstanding and (ii) extending the contract term from 12 to 14 months.

In November 2018, Estre Brazil concluded the sale of their shares to USA Global, agreeing the payment of the remaining balance of R$ 2,817 as of December 31, 2018, divided into 6 installments with due date from December 2018 to June 2019. All financial rights on its shares in Doña Juana were transferred to USA Global. As of December 31, 2018, the Company had an overdue installment amounting to R$ 620.

The amounts recorded on the transaction date are as follows:

Sale of Azaléia Empreendimentos e Participações S.A. (“Azaléia”)

On May 5, 2015, Estre Brazil entered into a purchase and sale agreement to sell 100% of its interest in Azaléia, to Limpus, for R$30,300. The purpose of such transaction was to divest of certain of Estre Brazil’s collections operations in the region of Ribeirao Preto conducted through Geo Vision Soluções Ambientais e Energia S.A., (“Geo Vision”), which it acquired in 2012. The Companyspun-off these collections operations into Azaléia, a newly-formed entity, which it later sold to Limpus, an entity that was controlled by the original sellers of Geo Vision.

There was no cash exchanged as part of the Azaléia transaction. In connection with the original acquisition of Geo Vision by Estre Brazil, Estre Brazil had a remaining balance of R$39,800 to be paid to the seller as of December 31, 2016. As Limpus was an entity wholly-owned by the original sellers of Geo Vision, at the time of settlement of the sale of Azaléia in 2016, Estre Brazil fully offset its accounts receivable from this transaction, amounting to R$41,300 as of December 31, 2016, as adjusted by interest, with Estre Brazil’s accounts payable on the original Geo Vision of transaction of R$39,800. The transaction resulted in the recognition of a loss of R$ 1,445 of that year.

Allegations and Investigations Regarding the Company’s Supply Relationships

Operation “Lava-Jato” and its impacts on the Company and its investees

In 2014, the Brazilian Federal Police (“PF”) began an investigation intended to check for irregularities perpetrated by criminal organizations in several Brazilian states, involving Petrobras and its subsidiaries. In connection with the investigations conducted by the Federal Public Prosecutor (“MPF”), Mr. Paulo Roberto Costa, former director of Petroleo Brasileiro S.A. – Petrobras, signed a plea bargain agreement, partly citing the Company in depositions on September 5, 2014, made public by the MPF on March 6, 2015. Estre Brazil was also partly cited in the plea bargain program of Mr. Sergio Machado, former CEO of Petrobras Transporte S.A. – Transpetro (��Transpetro”), made public in June 2016.

Company management stated that was not aware of the allegations mentioned in the deposition and that the Company does not admit any illegal acts, in accordance with its Code of Ethics and Anti-Corruption Policy. As a commitment to transparency and ethical conduct, the Company and its management made every effort to (i) obtain greater knowledge of the facts through the involvement of the Company’s internal legal department, the Compliance area and the hiring of independent investigation experts; (ii) continue to improve the Company’s governance, internal controls and integrity program; (iii) continue to monitor the matter.

In connection with the above, with the approval of the existing Board of Directors before December 21, 2017, engaged in 2018, the Company hired independent expert to further analyze the findings presented in the 2016 report, widening the scope of work to 56 suppliers and extending the period under investigation from 2010 through 2017, with the following main objectives:

•

Suppliers—analysis of agreements, payments and evidence of services (services provided to the Company and its investees) and goods purchased from the main suppliers and service providers;

•

Integrity due diligence—on 56 suppliers and current and past management members relating to the period under analysis; and

•

Analysis of emails—of the current main Executive Officers and of those who worked for the Company during the period under scope.

Operation “Lava-Jato” and its impacts on the Company and its investees(Continued)

As a result of the findings presented in the independent experts’ report, despite the lack of conclusive evidence of illegal payments related to the allegations made in Operation “Lava-Jato”, the Company’s management made in 2017, an accounting adjustment resulting in thewrite-off of property, plant and equipment items totaling R$53,407, related to payments for which there is lack of sufficient evidence that good and services were actually provided. Additionally, the Company’s Management, with the Board of Directors’ approval, engaged experts to conduct an investigation of the bidding processes won by the Company with Petrobras, which was concluded in January 2018, with no findings.

On January 31, 2019, the Brazilian Federal Police executed search warrants at various locations in the State of São Paulo, including at the Company’s corporate headquarters. The Company understands this was part of investigations related to contracts previously investigated, as the focus of the search involved the same suppliers, in the period from 2008 to 2014 between Estre Brazil and some of its former subsidiaries and Transpetro, a subsidiary of Petrobras. No additional internal investigation or by an independent expert was conducted since the referred contracts were already subject to the internal investigation. The Company understands the search warrants were a result of a plea bargain agreement entered into by Mr. Sergio Machado, which was entered into as a result of Operation Lava Jato.

As part of this action by the Brazilian Federal Police, temporary arrest warrants were also executed, including among others, the arrest of the founder and former chairman and a former senior employee of Estre Brazil.

If Estre Brazil is charged with any violations as a result of this investigation, Estre Brazil may be subject to sanctions, including potential monetary fines, asset freezes, ineligibility from contracting with state-owned or government entities, injunctions against future conduct, profit disgorgements, disqualifications from directly or indirectly engaging in certain types of businesses, the loss of business permits or other restrictions that could have a material adverse effect on the Company’s business, financial condition, results of operations or liquidity. As of the date of the issuance of these consolidated financial statements, none of the potential risks identified materialized. Management believes that all significant issues identified in the independent forensic experts’ report have been adjusted in the Company’s accounting records and does not expect additional charges being recorded in relation to the matter.

Estre Brazil is committed to the highest standards of compliance and will continue to cooperate with the relevant authorities.

Operation Descarte—Special Committee Internal Evaluation

On December 15, 2017, the Company’s indirect subsidiary, Cavo Serviços e Saneamento S.A. (“Cavo”) received an official tax infringement notice in the amount of R$90,634 challenging the deductibility of payments made to a number of specific suppliers in 2012, for which there is lack of sufficient evidence that goods or services were actually provided.

On December 22 and 27, 2017, Estre Brazil received two official tax infringement notices in the aggregate amount of R$121,778 challenging the deductibility of payments made to a number of specific suppliers from 2012 to 2015, for which there is lack of sufficient evidence that goods or services were actually provided.

Estre Brazil is challenging such assessment, and presented its defense on January 23, 2018, with no conclusion as of the date of the issuance of these consolidated financial statements. Following the receipt of these tax infringement notices above, Estre Brazil, following the directions of its general counsel, engaged an independent forensic services firm to investigate the relationship of Cavo’s subsidiary SPE Soma Soluções em Meio Ambiente Ltda. (“SPE Soma”) with certain suppliers. This internal investigation was only in its preliminary stages when, on March 1, 2018, the Brazilian Federal Police executed search warrants at the corporate offices of Estre Brazil and Soma.

As a result of the events of March 1, 2018, Estre Brazil significantly broadened the scope of the internal investigation process at the direction of a newly constituted Special Committee comprised of independent members of the Company’s Board of Directors. The internal investigation was conducted by external legal counsels specialized in forensic investigations with the support of other forensic service providers. The scope mainly include the analysis of payments to suppliers, focused in identification of the services provides / goods delivered, from a list of suppliers already being investigated by the tax authorities.

The internal investigation procedures involved analysis and review of relevant documentation and materials from past and present employees, interviews with certain individuals and a forensic analysis of financial transactions.

As a result of the investigation, Estre Brazil concluded that there were payments made to certain suppliers, particularly through Soma, for which there was insufficient evidence that goods and services were actually provided. Consequently, the Company recorded a loss of R$33,974 in the statement of profit or loss for the year ended December 31, 2017, of which R$555 was recorded in depreciation expenses, R$11,219 in general and administrative expenses, R$10,882 in other operating (expenses) income, net, and R$11,318 in finance expenses. No additional adjustments were made in 2018.

Operation Descarte—Special Committee Internal Evaluation(Continued)

Furthermore, the Operation Descarte effort of the Brazilian Federal Police was within the scope of the broader Lava Jato task force, with the objective of dismantling a criminal money-laundering network. The Company cannot predict whether these investigations will move forward and, if so, the duration, scope or ultimate outcome of these investigations. In the event the Company is charged with any violations as a result of the outcome of these investigations it could be subject monetary fines and potential ineligibility from contracting with state-owned or government entities, which could have a material adverse effect on the Company.

Through the efforts made by the Company up to the date of issuing these financial statements, management believes that all significant issues identified in the independent forensic experts’ report have been adjusted and does not expect additional charges being recorded in relation to the matter. However, despite the significant progress in terms of internal controls, the Company believes that there are still improvement opportunities to be achieved during 2019.

Internal Controls

Management and the Board of Directors do not tolerate any unlawful acts, therefore, the Company has been developing and implementing a number of measures to improve governance, internal controls and risk management, as shown in follows:

•

review of all Estre Brazil’s corporate policies, in order to strengthen the tone at the top that overriding of internal controls will not be tolerated;

•

reorganization of Estre Brazil senior management team;

•

the replacement of the senior management team at Soma;

•

expansion of the Compliance Integrity Program to all subsidiaries;

•

obtainment of ISO 37001 certification – Anti-bribery management systems;

•

maintenance of an integrity program; and

•

establishment of a Board of Directors with a majority of the members consisting of leading executives and other professionals that are experts in their respective fields as well as the establishment of an independent audit committee and corporate governance committee with expanded oversight functions.

These measures have been put in effect gradually in the Company and its subsidiaries, since the issues were identified at Soma.

The Company will continue to implement these controls in 2019, especially since the Company started to prepare their internal controls environment to comply with the requirements of Sarbanes Oxley Act (“SOx”) in the future.

Internal Controls

The Company has identified improvement areas, as follows, and expect to have all action plans fully implemented by the end of 2019:

•

making certain adjustments to the Company’s compliance infrastructure to strengthen the independence of our compliance function and eliminate opportunities to override controls across our organization, including at Soma and all our subsidiaries and joint ventures;

•

further upgrading our ERP business process management software, which we first implemented in 2016, in order to better manage our business and automate many back office functions with the goal of improving our internal controls over financial reporting and streamlining monthly, quarterly andyear-end closings. The full system migration is expected to be completed by the end of 2019;

•

complete review of the purchase to pay process, in order to improve the efficiency, approval structure and reduce the risks of fraud;

•

enhancing and continuing to improve the vendor master data, due diligence, know your client procedures, procurement and payment procedures and associated controls;

•

implementing a workflow tool, allowing the controlled exchange of information to facilitate timely and effective communication amongst the legal, financial and accounting departments and prompt registration of all transactions; and

2.1.

Basis of preparation and presentation of financial statements

The Transaction described in Note 1 above, was accounted for as a reorganization and recapitalization transaction whereby Estre Ambiental, Inc. was created as a holding company of Estre Brazil and concurrently issue new ordinary shares to the former shareholders of Estre USA and the PIPE investors in exchange of cash (recapitalization). As a result, the assets and liabilities of Estre Brazil are carried at historical cost and there was nostep-up in basis or goodwill or other intangible assets recorded as a result of the Transaction.

As a result, the consolidated financial statements filed with the SEC by the Company subsequent to the completion of the Transaction are presented “as if” Estre Brazil is the predecessor of the Company. The historical operations of Estre Brazil are deemed to be those of the Company. Thus, these consolidated financial statements reflect (i) the historical operating results of Estre Brazil prior to the Transaction, as restated (Note 1.5); (ii) the consolidated results of the Company and Estre Brazil following the Transaction; (iii) the assets and liabilities of Estre Brazil at their historical cost; and (iv) the Company’s equity and earnings per share for all periods presented. The number of ordinary shares issued by Estre Ambiental, Inc. as a result of the Transaction is reflected retroactively to January 1, 2015, for purposes of calculating earnings per share in all prior periods presented.

The preparation of the consolidated financial statements requires the use of certain critical accounting estimates and also the exercise of judgment by Company management in the process of application of its accounting practices. Areas involving a higher degree of judgment, with greater complexity, and areas where assumptions and estimates that are significant to the consolidated financial statements are disclosed in Note 2.21.

The Company’s consolidated financial statements have been prepared in accordance with International Financial Reporting Standards (“IFRS”) issued by the International Accounting Standards Board (“IASB”). The consolidated financial statements were approved by the Board of Directors and by the Executive Board on May 13, 2019.

The consolidated financial statements have been prepared on a historical cost basis, except for certain financial instruments at fair value described in Note 2.7 and certain assets measured at fair value on the date of the business combination, described in Note 2.4.

2.2.

Basis of consolidation (Continued)

A subsidiary is fully consolidated from the date the control is obtained, and ceases when the Company loses control of the subsidiary. The Company evaluates existence and effect of potential voting rights currently exercisable or convertible, shareholders agreement and company management policies are taken into account in determining whether the Company controls the entity or not.

Control is achieved when the Company is exposed, or has rights, to variable returns from its involvement with the investee and has the ability to affect those returns through its power over the investee. Specifically, the Company controls an investee if, and only if, the Company has:

•

Power over the investee (i.e., existing rights that give it the current ability to direct the relevant activities of the investee)

•

Exposure, or rights, to variable returns from its involvement with the investee

•

The ability to use its power over the investee to affect its returns

Generally, there is a presumption that a majority of voting rights results in control. To support this presumption and when the Company has less than a majority of the voting or similar rights of an investee, the Company considers all relevant facts and circumstances in assessing whether it has power over an investee, including:

•

The contractual arrangement(s) with the other vote holders of the investee

•

Rights arising from other contractual arrangements

•

The Company’s voting rights and potential voting rights

The financial years and the closing periods of direct and indirect subsidiaries included in the consolidation are the same as those of the Company, and accounting practices and policies have been consistently applied by the consolidated companies and are consistent with those used in the previous years. All consolidated intercompany balances and transactions were eliminated in consolidation.

2.3.

Foreign currency translation

Functional and reporting currencies

In evaluating the functional currency of the Company, management considered the factors and indicators contained in IAS 21 – The effect of changes in foreign exchange rates. Considering that the Company is a holding that incur in limited expenses, Estre Inc. is using the currency of the local environment of Estre Brazil as its functional currency, as this is the environment which drives the dividend income it receives, which is its primary source of revenue. Therefore, the functional currency of the Company is Brazilian Reais.

The financial statements of each subsidiary included in the Company’s consolidation and those used as a basis for valuation of investments using the equity method are prepared using the functional currency of each entity, and for entities whose functional currencies are different from the Company’s reporting currency, their assets and liabilities are translated into the Company’s reporting currency at the closing date and their statements of profit or loss are translated at exchange rate prevailing at the dates of the transactions.

The exchange differences arising on translation for consolidation are recognized in other comprehensive income.

Transactions and balances

Transactions in foreign currencies are translated using the exchange rates prevailing on the transaction dates or on the valuation date, for remeasured items. The foreign exchange gains and losses resulting from the settlement of these transactions and resulting from the translation at exchange rates at the end of the year relating to monetary assets and liabilities denominated in foreign currencies are recognized in the statement of profit or loss.

2.4.

Business combination

Business combinations are accounted for using the acquisition method. The cost of an acquisition is measured as total consideration transferred, measured at fair value at the acquisition date, and the amount of anynon-controlling interests in the acquiree. For each business combination, the Company elects whether to measure thenon-controlling interest in the acquiree at fair value or at the proportionate share of the acquiree’s identifiable net assets. Costs directly attributable to the acquisition are expensed as incurred.

2.4.

Business combinations(Continued)

When acquiring a business, the Company assesses the financial assets and liabilities assumed, for appropriate classification and designation in accordance with contractual terms, economic circumstances and pertinent conditions at the acquisition date.

If the business combination is achieved in stages, the fair value at the acquisition date of the previously held equity interest in the acquiree is remeasured at fair value at the latest acquisition date, and impacts are recognized in the statement of profit or loss.

Any contingent consideration to be transferred by the acquirer is recognized at fair value at the acquisition date. Subsequent changes to the fair value of the contingent consideration considered as an asset or liability will be recognized in the statements of profit or loss.

Goodwill is initially measured at cost, being the excess of the aggregate of the consideration transferred and the fair value of net assets acquired. If the consideration is lower than the fair value of net assets acquired, the difference is recognized as a bargain gain in the statement of profit or loss.

After initial recognition, goodwill is measured at cost, less any accumulated impairment losses. For impairment test purposes, goodwill acquired in a business combination is allocated to each of the Company’s cash-generating units that are expected to benefit from the synergies arising from the combination, irrespective of whether other assets or liabilities of the acquiree are assigned to those units.

When goodwill forms part of a cash generating unit and a portion of that unit is disposed of, the goodwill associated to the disposed portion must be included in the transaction upon carrying amount of the operation when determining disposal gains or losses. Goodwill disposed in these circumstances is measured based on the relative values of the disposed operations and the cash generating unit retained.

Investment in associates, joint operations and joint ventures

An associate is an entity in which the Company exercises significant influence. Significant influence is the power to participate in decisions on operating policies of the investee. It does not hold, however, control or joint control over those policies.

A joint operation (JO) is a type of joint arrangement in which the parties with joint control of the arrangement have rights to the assets and obligations for the liabilities relating to the arrangement.

In relation to its interests in JOs, the financial statements of the Company includes:

•

Assets, including its share of any assets held jointly

•

Liabilities, including its share of any liabilities incurred jointly

•

Revenue from the sale of its share of joint operation

•

Share of the revenue from the sale of the output by the joint operation

•

Expenses, including its share of any expenses incurred jointly

All such amounts are measured in accordance with the terms of each arrangement which are in proportion to the Company’s interest in the JO.

A joint venture is a type of joint arrangement whereby the parties that have joint control of the arrangement have rights to the net assets of the joint venture. Joint control is the contractually agreed sharing of control of an arrangement, which exists only when decisions about the relevant activities require the unanimous consent of the parties sharing control.

The Company’s investments in its associates and joint ventures, shown in the table below, are accounted for using the equity method:

Investment in associates, joint operations and joint ventures(Continued)

2.5.1.

Investment in associates and joint ventures

Under the equity method, the investment in associate and joint ventures is initially recognized at cost. The carrying amount of the investment is adjusted to recognize changes in the Company’s share in the net assets of the associate since the acquisition date. Goodwill relating to the associate is included in the investment and is not tested for impairment separately.

The statement of profit or loss reflects the Company’s share of the results of operations of the associate and joint venture. Any changes in other comprehensive income in these investees is presented in the Company’s other comprehensive income. In addition, when there has been a change directly recognized in the equity of the associate the Company recognizes its share of any changes, in the statements of changes in equity when applicable. Unrealized gains and losses resulting from transactions between the Company and the associate are eliminated to the extent of the interest in the associate and joint venture.

The aggregate of the Company’s share of profit or loss of an associate or joint venture is stated in the statements of profit or loss representing profit after tax and interest held bynon-controlling interest in the subsidiaries of the associate or joint venture.

Current versusnon-current classification

The Company presents assets and liabilities in the statement of financial position based on current andnon-current classification. An asset is classified as current when:

•

It is expected to be realized within 12 months from the reporting date; or

•

It consists of cash and cash equivalents, unless restricted from being exchanged or used to settle a liability for at least 12 months after the reporting period.

All other assets are to be classified asnon-current.

A liability is current when:

•

It is expected to be settled in the normal operating cycle;

•

It is held primarily for the purpose of trading;

•

It is due to be settled within twelve months after the reporting period; or

•

There is no unconditional right to defer the settlement of the liability for at least twelve months after the reporting period

The Company classified all other liabilities asnon-current. Deferred tax assets and liabilities are classified asnon-current assets and liabilities.

Fair value measurement

Fair value is the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants on the measurement date. Fair value measurement is based on the presumption that the transaction to sell the asset or transfer the liability takes place either:

•

In the principal market for the asset or liability; or

•

In the absence of a principal market, in the most advantageous market for the asset or liability.

The fair value of an asset or a liability is measured using the assumptions that market participants would use when pricing an asset or liability, assuming that market participants act in their economic best interest.

The fair value measurement of anon-financial asset takes into consideration the ability of a market participant to generate economic benefits through the optimal use of the asset or selling it to another market participant that would also optimally use the asset.

The Company uses valuation techniques appropriate for the circumstances and for which there is sufficient data for fair value measurement, maximizing the use of relevant available information and minimizing the use of unavailable information.

All assets and liabilities for which the fair value is measured in the financial statements are categorized within the fair value hierarchy described below, based on the lowest level of information that is significant to the fair value measurement as a whole:

•

Level 1 - quoted prices (unadjusted) in active markets for identical assets or liabilities;

•

Level 2 - valuation techniques for which the lowest level input that is significant to the fair value measurement is either directly or indirectly observable; and

•

Level 3 - valuation techniques for which the lowest level input that is significant to the fair value measurement is unobservable.

Fair value measurement(Continued)

For assets and liabilities that are recognized in the financial statements on a recurring basis, the Company determines whether there were transfers between hierarchy levels, byre-assessing categorization (based on the lowest level input that is significant to the fair value measurement as a whole) at the end of each reporting period.

For the purposes of fair value disclosures, the Company has determined classes of assets and liabilities based on the nature, characteristics and risks of assets or liabilities and the fair value hierarchy level, as mentioned above.

The fair values of financial instruments measured at amortized cost are disclosed in Note 30.

Revenue recognition

Beginning on January 1, 2018 the IFRS 15 – Revenue from Contracts with Customers came into effect, which establishes a five-step model to account for revenue arising from contracts with customers and require that revenue be recognized at an amount that reflects the consideration to which the entity expects to be entitled in exchange of transferring good or services to customers. The five steps model is as follows:

Identification of the contract with the client;

ii)

Identification of performance obligations in the contract;

iii)

Determination of the transaction price;

iv)

Allocation of the transaction price to the performance obligations in the contract; and

Recognition of revenue upon satisfaction of the performance obligations.

Revenues shall be recognized at the amount that reflects the consideration or which the Company expect of receiving in exchange of transferring goods or services to the customers.

Revenue recognition (Continued)

Revenue From Services

Collection & Cleaning Services - Revenue from collection & cleaning services is recognized when the service is provided. The Company recognizes revenue for the service provided, using the transaction price the Company expects to be entitled to.

Landfills - waste that cannot be recycled is sent to the most appropriate final disposal, in sanitary landfills. The Company operates 12 landfills across Brazil, serving public and private entities. Revenues is recognized when the disposals are received in the Company’s landfills, at the transaction price the Company expects to be entitled to.

Value Recovery - Value recovery services are related to a series of solutions that ensure the maximum use of the waste, with its reuse or search for new technology to recycle the materials. Revenue is recognized when the service is provided. The Company measures the provided service by the transaction price the Company expected to be entitled to.

O&G - Revenue from services contracts provided to the oil & gas industry is recognized when the service is provided, at the transaction price the Company expects to be entitled to.

Contract assets, contract liabilities, receivables:

A contract asset is the right to consideration in exchange for the services provided to the customer. If the Company performs by providing services to a customer before the customer pays consideration or before payment is due, a contract asset is recognized for the earned consideration that is conditional. For services rendered that customers have not yet approved at the end of the period, revenue is recognized based on estimates or work performed.

A contract liability is the obligation to provide services to a customer for which the Company has received consideration (or an amount of consideration is due) from the customer. If a customer pays consideration before the Company provides services to the customer, a contract liability is recognized when the payment is made or the payment is due (whichever is earlier). Contract liabilities are recognized as revenue when the Company performs under the contract.

A receivable represents the Company’s right to an amount of consideration that is unconditional (i.e., only the passage of time is required before payment of the consideration is due). Refer to accounting policies of financial assets in section Financial instruments – initial recognition and subsequent measurement.

Revenue recognition (Continued)

Variable consideration

Variable consideration is included in the transaction price if it is highly probable that no significant reversal of revenue will occur once associated uncertainties are resolved. Significant estimates are involved in determining the amount of variable consideration which is calculated by using either the expected value or the most likely amount depending on which is expected to better predict the amount of variable consideration. Consideration is adjusted for the time value of money if the period between the provided services and the receipt of payment exceeds twelve months and the financing benefit.

The Company is required to determine whether there is a significant financing component in its contracts. According to paragraph 60 of this standard, in determining the transaction price an entity shall adjust the amount of the consideration promised for the effects of the time value of money when a significant financing component is present. A significant financing component may exist independently if the promise of financing is expressly stated in the contract or implied in the terms of payment agreed by the parties to the contract. The Company should analyze if the payment period agreed by the parties to the contract (expressly or implicitly) provides the client or the entity with a significant financial benefit from the transfer of goods or services to the customer.

Based on the above, the Company performs an analysis to identify the existence of a significant financing component for public sector clients, since the average collection term for this client portfolio is approximately six months. The Company considered the average rate of 8.50% p.a. for the discount rate of 2018 (8.40% at December 31, 2017), which represents the discount rate usually applied by the Company to calculate the present value of its non-current assets and liabilities.

Revenue from the sale of products

Revenue from the sale of products refers to the sale of scrap, fuel gas, carbon credit, electric power. For the sale of products, revenue is recognized when the performance obligations is satisfied at the time the control of the product sold is transferred to the customer, usually at the time of receipt and acceptance.

Tax

Current income and social contribution taxes

Current income and social contribution taxes are calculated in accordance with tax legislation and tax rates currently enacted, at the statutory rates of 15%, plus a surtax 10% for income tax and 9% for social contribution tax.

Current income and social contribution taxes related to items recognized directly in equity are also recognized in equity. Management regularly assesses the tax positions in circumstances in which tax regulations require interpretation, and sets up provisions when appropriate.

Deferred taxes

Deferred tax is provided using the liability model or temporary differences between the tax bases of asset and liability and the carrying amount for financial reporting purposes at the reporting date.

Deferred tax assets are recognized for all deductible temporary differences, credits and unused tax losses, to the extent it is probable that taxable profit will be available so that deductible temporary differences may be realized and unused credits and tax losses may be used. Deferred tax liabilities are recognized for all taxable temporary differences except:

Tax(Continued)

Deferred taxes (Continued)

•

When a deferred tax liability arises upon initial recognition of goodwill or of an asset or liability in a transaction other than a business combination and, at the time of the transaction affects neither the accounting profit nor taxable profit or loss; and

•

On taxable temporary differences related to investments in subsidiaries, when the timing of the reversal of temporary differences can be controlled and the temporary differences will likely not reverse in the near future.

The carrying amount of deferred tax assets is reviewed at each statement of financial position date and reduced to the extent that it is no longer probable that future taxable profits will be available to allow all or part of the deferred tax asset to be utilized. Deferred tax assets written off arere-assessed at each reporting date and recognized to the extent that it is probable that future taxable profit will allow deferred tax assets to be recovered.

Deferred taxes related to items recognized directly in equity are also recognized in equity, and not recognized in the statements of profit or loss. Deferred tax items are recognized based on the transaction which gave rise to the deferred tax, in comprehensive income or directly in equity.

Deferred tax assets and liabilities are presented net if there is a legal or contractual right to offset tax assets against tax liabilities and the deferred taxes relate to the same taxed entity and are subject to the same taxing authority.

Sales taxes

Revenues, expenses and assets are recognized net of sales tax, except:

•

When the sales taxes incurred on the purchase of goods or services are not recoverable from tax authorities, in which case the sales tax is recognized as part of the cost of acquiring the asset or expense item, as applicable; and

•

When the amounts receivable or payable are stated with the amount of sales taxes included. The net amount of sales taxes, recoverable or payable to the tax authority, is included as part of receivables or payables in the statement of financial position.

These are subject to lower COFINS and PIS rates of 3.00% and 0.65%, respectively. However, PIS and COFINS taxes on purchases may not be claimed back and will not generate tax credits under the presumed profits basis.

(b)

ISS rates vary according to the municipality; the ISS rate stated in the table above is the most commonly levied on the Company’s operations.

(c)

ICMS is taxed on the movement of goods. The tax payable is due on sales net purchases. The rates vary across different products and Brazilian states. The State of São Paulo levies ICMS at standard rate of 18.00%.

Tax on purchases

Taxes paid on purchases of goods and services can normally be recovered as tax credits, at the following statutory rates:

Non-current assets held for sale and discontinued operations

2.10.1.

Non-current assets held for sale

The Company classifies assets and liabilities held for sale from discontinued operations if the carrying amounts are expected to be recovered principally through a sale transaction rather than through continuing use. These assets and liabilities classified as held for sale are measured at the lower of carrying amount and fair value, less costs to sell. Costs incurred in a sales transaction are incremental costs directly attributable to the sale, excluding finance expenses and income tax expenses.

The criteria for classification of items held for sale are considered as having been met only when a sales transaction is highly probable to occur and when such items are available for immediate sale in the present condition.

Management should be committed to the completion of the sale within one year from the date of classification of assets and liabilities as held for sale.

Property, plant and equipment and intangible assets are no longer depreciated or amortized from the moment they are classified as held for sale or distribution.

Assets and liabilities classified as held for sale are presented separately as current items on the statement of financial position.

2.10.2.

Discontinued operations

An asset qualifies as a discontinued operation if it represents a component of an entity that has been sold or classified as held for sale, and:

•

Represents a separate major line of business or geographical area of operations;

•

Is part of a single coordinated plan to dispose of a separate major line of business or geographical area of operations; or

•

Is a subsidiary acquired exclusively for the purpose of resale.

Discontinued operations are excluded from profit or loss of continuing operations, and presented as a single amount in profit or loss after taxes under discontinued operations in the statement of profit or loss.

Further disclosures are presented in Note 10.2. All other notes to the financial statements include amounts for continuing operations, unless otherwise stated.

Property, plant and equipment

Property, plant and equipment is stated at historical cost of acquisition or construction cost, less accumulated depreciation and accumulated impairment losses, if any.

Ordinary maintenance expenses are recognized in the statement of profit or loss in the period they are incurred.

Depreciation is calculated on a straight-line basis over the estimated useful lives of the assets. The residual values and useful lives are reviewed at least at eachyear-end and adjusted prospectively, if appropriate.

The useful life is the length of time the Company expects to use the asset. The weighted average rates of depreciation used for each asset class are described in Note 11.

An item of property, plant and equipment is derecognized upon disposal or when no future economic benefits are expected from its use or disposal. Any gain or loss on derecognition of the asset (calculated as the difference the net disposal proceed and the carrying amount of the asset) is recorded in “Other operating income (expenses)” in the statement of profit or loss.

2.12.

Intangible assets

Intangible assets acquired separately are measured at cost upon their initial recognition. The cost of intangible assets acquired in a business combination is the fair value at the acquisition date. After initial recognition, intangible assets are stated at cost less accumulated amortization and accumulated impairment losses. Internally generated intangible assets, excluding capitalized development costs, are not capitalized and the related expenditure is reflected in the statement of profit or loss for the period they are incurred.

Intangible assets are assessed as having finite or indefinite useful lives. Intangible assets with finite lives are amortized over the useful economic life and assessed for impairment whenever there is indication that the intangible asset may be impaired.

The period and the amortization method for intangible assets with finite lives are reviewed at least once a year. Changes in estimated useful life or the expected consumption of the future economic benefits of these assets are accounted for by changing the amortization period or method, as appropriate, and treated as changes in accounting estimates. Amortization of intangible assets with finite lives is recognized in the statement of profit or loss in the expense category consistent with the use of intangible assets.

Intangible assets with indefinite useful lives are not amortized but tested annually for impairment either individually or at the level of cash generating unit. The assessment of indefinite life is reviewed annually to determine whether this evaluation is still justifiable. Otherwise, the change in the useful life assessment from indefinite to finite is made prospectively.

Gains and losses arising from derecognition of an intangible asset are measured as the difference between the net disposal proceeds and the carrying value of the asset, and recognized in the statement of profit or loss.

2.13.

Loss on impairment ofnon-financial assets

Management annually reviews the carrying amount of assets for purposes of evaluating events or changes in economic, operating or technological circumstances that may indicate impairment or loss of their recoverable value. When such evidence is identified, and the carrying amount of an asset exceeds its recoverable amount, the asset is considered impaired and is written down to its recoverable amount.

Loss on impairment ofnon-financial assets(Continued)

The recoverable amount of an asset or of a given cash generating unit is defined as the higher of the value in use and fair value less costs to sell.

In estimating the assetvalue-in-use, the estimated future cash flows are discounted to their present value using apre-tax discount rate that reflects the weighted average cost of capital for the industry in which the cash generating unit operates. The net sales value is determined, whenever possible, based on a firm sales agreement in an arm’s length transaction between knowledgeable, willing parties, adjusted by expenses attributable to the asset sale, or when there is no binding sale agreement based on the market price of an active market, or in the most recent transaction price with similar assets.

The following criteria are also applied in assessing impairment of specific assets:

PP&E

The test of PP&E impairment is performed annually or when circumstances indicate an impairment of the carrying value. At December 31, 2018 the Company recognized impairment losses on PP&E (see Note 11).

Goodwill

The test of goodwill impairment is performed annually at December 31, at the cash generating unit level.

Intangible assets

Intangible assets with indefinite useful lives are tested for impairment annually at December 31, either individually or at the level of cash generating unit, as appropriate, and when circumstances indicate an impairment of the carrying amount.

The Company conducted impairment tests and recognized impairment losses on identifiable intangible assets and goodwill arising from business combinations (see Note 12).

Financial assets

Initial recognition and measurement

Company determines financial assets are classified, at initial recognition, as subsequently measured at amortized cost, fair value through other comprehensive income (OCI), and fair value through profit or loss.

The classification of financial assets at initial recognition depends on the financial asset’s contractual cash flow characteristics and the Company’s business model for managing them. The Company initially measures a financial asset at its fair value plus, in the case of a financial asset not at fair value through profit or loss, transaction costs. Trade receivables that do not contain a significant financing component or for which the Company has applied the practical expedient are measured at the transaction price determined under IFRS 15.

In order for a financial asset to be classified and measured at amortized cost or fair value through OCI, it needs to give rise to cash flows that are ‘solely payments of principal and interest (SPPI)’ on the principal amount outstanding. This assessment is referred to as the SPPI test and is performed at an instrument level.

The Company’s business model for managing financial assets refers to how it manages its financial assets in order to generate cash flows. The business model determines whether cash flows will result from collecting contractual cash flows, selling the financial assets, or both.

Purchases or sales of financial assets that require delivery of assets within a time frame established by regulation or convention in the market place (regular way trades) are recognized on the trade date, i.e., the date that the Company commits to purchase or sell the asset.

Subsequent measurement

For purposes of subsequent measurement, financial assets are classified in four categories:

•

Financial assets at amortized cost (debt instruments)

•

Financial assets at fair value through OCI with recycling of cumulative gains and losses (debt instruments)

•

Financial assets designated at fair value through OCI with no recycling of cumulative gains and losses upon derecognition (equity instruments)

•

Financial assets at fair value through profit or loss

Financial assetsat amortized cost (debt instruments)

This category is the most relevant to the Company. The Company measures financial assets at amortized cost if both of the following conditions are met:

•

The financial asset is held within a business model with the objective to hold financial assets in order to collect contractual cash flows and:

•

The contractual terms of the financial asset give rise on specified dates to cash flows that are solely payments of principal and interest on the principal amount outstanding

Financial assets at amortized cost are subsequently measured using the effective interest (EIR) method and are subject to impairment. Gains and losses are recognized in profit or loss when the asset is derecognized, modified or impaired.

The Company´s financial assets at amortized cost include trade accounts receivables, contract assets and receivables from related parties under other current and non-current financial assets.

Subsequent measurement (Continued)

Financial assets at fair value through OCI (debt instruments)(Continued)

The Company measures debt instruments at fair value through OCI if both of the following conditions are met:

•

The financial asset is held within a business model with the objective of both holding to collect contractual cash flows and selling and;

•

The contractual terms of the financial asset give rise on specified dates to cash flows that are solely payments of principal and interest on the principal amount outstanding

For debt instruments at fair value through OCI, interest income, foreign exchange revaluation and impairment losses or reversals are recognized in the statement of profit or loss and computed in the same manner as for financial assets measured at amortized cost. The remaining fair value changes are recognized in OCI. Upon derecognition, the cumulative fair value change recognized in OCI is recycled to profit or loss.

Financial assets designated at fair value through OCI (equity instruments)

Upon initial recognition, the Company can elect to classify irrevocably its equity investments as equity instruments designated at fair value through OCI when they meet the definition of equity under IAS 32 Financial Instruments: Presentation and are not held for trading. The classification is determined on an instrument-by-instrument basis.

Gains and losses on these financial assets are never recycled to profit or loss. Dividends are recognized as other income in the statement of profit or loss when the right of payment has been established, except when the Company benefits from such proceeds as a recovery of part of the cost of the financial asset, in which case, such gains are recorded in OCI. Equity instruments designated at fair value through OCI are not subject to impairment assessment.

Financial assets (Continued)

Financial assets at fair value through profit or loss

Financial assets at fair value through profit or loss include financial assets held for trading, financial assets designated upon initial recognition at fair value through profit or loss, or financial assets mandatorily required to be measured at fair value. Financial assets are classified as held for trading if they are acquired for the purpose of selling or repurchasing in the near term. Derivatives, including separated embedded derivatives, are also classified as held for trading unless they are designated as effective hedging instruments. Financial assets with cash flows that are not solely payments of principal and interest are classified and measured at fair value through profit or loss, irrespective of the business model. Notwithstanding the criteria for debt instruments to be classified at amortized cost or at fair value through OCI, as described above, debt instruments may be designated at fair value through profit or loss on initial recognition if doing so eliminates, or significantly reduces, an accounting mismatch.

Financial assets at fair value through profit or loss are carried in the statement of financial position at fair value with net changes in fair value recognized in the statement of profit or loss.

iii)

Derecognition

A financial asset (or, where applicable, a part of a financial asset or part of a group of similar financial assets) is primarily derecognized (i.e., removed from the Company´s statement of financial position) when:

Derecognition(Continued)

•

The rights to receive cash flows from the asset have expire or:

•

The Company has transferred its rights to receive cash flows from the asset or has assumed an obligation to pay the received cash flows in full without material delay to a third party under a ‘pass-through’ arrangement; and either (a) the Company has transferred substantially all the risks and rewards of the asset, or (b) the Company has neither transferred nor retained substantially all the risks and rewards of the asset, but has transferred control of the asset.

When the Company has transferred its rights to receive cash flows from an asset or has entered into a pass-through arrangement, it evaluates if, and to what extent, it has retained the risks and rewards of ownership. When it has neither transferred nor retained substantially all of the risks and rewards of the asset, nor transferred control of the asset, the Company continues to recognize the transferred asset to the extent of its continuing involvement. In that case, the Company also recognizes an associated liability. The transferred asset and the associated liability are measured on a basis that reflects the rights and obligations that the Company has retained.

Continuing involvement that takes the form of a guarantee over the transferred asset is measured at the lower of the original carrying amount of the asset and the maximum amount of consideration that the Company could be required to repay.

iv)

Impairment of financial assets

The Company recognizes an allowance for expected credit losses (ECLs) for all debt instruments not held at fair value through profit or loss. ECLs are based on the difference between the contractual cash flows due in accordance with the contract and all the cash flows that the Company expects to receive, discounted at an approximation of the original effective interest rate. The expected cash flows will include cash flows from the sale of collateral held or other credit enhancements that are integral to the contractual terms.

Impairment of financial assets(Continued)

ECLs are recognized in two stages. For credit exposures for which there has not been a significant increase in credit risk since initial recognition, ECLs are provided for credit losses that result from default events that are possible within the next 12-months (a 12-month ECL). For those credit exposures for which there has been a significant increase in credit risk since initial recognition, a loss allowance is required for credit losses expected over the remaining life of the exposure, irrespective of the timing of the default (a lifetime ECL).

For trade receivables and contract assets, the Company applies a simplified approach in calculating ECLs. Therefore, the Company does not track changes in credit risk, but instead recognizes a loss allowance based on lifetime ECLs at each reporting date. The Company has established a provision matrix that is based on its historical credit loss experience, adjusted for forward-looking factors specific to the debtors and the economic environment.

Financial liabilities

Initial recognition and measurement

Financial liabilities are classified, at initial recognition, as financial liabilities at fair value through profit or loss, loans and borrowings, payables, or as derivatives designated as hedging instruments in an effective hedge, as appropriate.

All financial liabilities are recognized initially at fair value and, in the case of loans and borrowings and payables, net of directly attributable transaction costs.

The Company´s financial liabilities include loans and financing, trade accounts payable, debentures, loans from related parties, accounts payable from land and others asset acquisition, put option on the Company’s shares and obligations relating to discontinued operations.

Subsequent measurement

The measurement of financial liabilities depends on their classification, which can be as follows:

Financial liabilities at fair value through profit or loss

Financial liabilities at fair value through profit or loss include financial liabilities held for trading and financial liabilities designated upon initial recognition as at fair value through profit or loss.

Financial liabilities are classified as held for trading if they are incurred for the purpose of repurchasing in the near term. This category also includes derivative financial instruments entered into by the Company that are not designated as hedging instruments in hedge relationships as defined by IFRS 9. Separated embedded derivatives are also classified as held for trading unless they are designated as effective hedging instruments.

Gains or losses on liabilities held for trading are recognized in the statement of profit or loss.

Financial liabilities designated upon initial recognition at fair value through profit or loss are designated at the initial date of recognition, and only if the criteria in IFRS 9 are satisfied. The Company has not designated any financial liability as at fair value through profit or loss, as of December 31, 2018 there is no derivative transaction.

Loans and borrowings

This is the category most relevant to the Company. After initial recognition, interest-bearing loans and borrowings are subsequently measured at amortized cost using the EIR method. Gains and losses are recognized in profit or loss when the liabilities are derecognized as well as through the EIR amortization process. Amortized cost is calculated by taking into account any discount or premium on acquisition and fees or costs that are an integral part of the EIR. The EIR amortization is included as finance costs in the statement of profit or loss. This category generally applies to interest-bearing loans and borrowings. For more information, refer to Note 13.

iii)

Derecognition(write-off)

A financial liability is derecognized when the obligation under the liability is discharged or cancelled or expires. When an existing financial liability is replaced by another from the same lender on substantially different terms, or the terms of an existing liability are substantially modified, such an exchange or modification is treated as the derecognition of the original liability and the recognition of a new liability. The difference in the respective carrying amounts is recognized in the statement of profit or loss.

Offsetting of financial instrument

Financial assets and financial liabilities are offset and the net amount is reported in the consolidated statement of financial position if there is a currently enforceable legal right to offset the recognized amounts and there is an intention to settle on a net basis, to realize the assets and settle the liabilities simultaneously.

2.15.

Inventories

Inventories are valued at the lower of cost and net realizable value. Inventories are mainly comprised of maintenance materials. Net realizable value is the estimated selling price in the ordinary course of business, less estimated costs of completion and costs the estimated costs necessary to make the sales.

2.16.

Cash and cash equivalents

Cash and cash equivalents comprise cash at banks, on hand and short-term investments with maturities of less than three months and which are subject to an insignificant risk of changes in value. Short-term investments included in cash equivalents are comprised of bank deposit certificates and repurchase agreements, both with daily liquidity, stated at acquisition cost plus accrued interest.

2.17.

Provisions

Provisions are recognized when the Company has a present obligation (legal or constructive) as a result of a past event, it is probable that an outflow of resources embodying economic benefits will be required to settle the obligation and a reliable estimate can be made of the amount of the obligation. When the Company expects some or all of a provision to be reimbursed, for example, under an insurance contract, the reimbursement is recognized as a separate asset, but only when the reimbursement is virtually certain.

The expense related to any provision is presented in the statement of profit or loss, net of any expected reimbursement.

Provision for landfill closure

The Company records the provision for decommissioning costs in relation to the closure and post-closure of landfill as the capacity of the landfill is consumed. The significant accounting aspects are summarized below:

Decommissioning costs are recorded for at the present value of expected costs to settle the obligation using estimated cash flows and are recognized as part of the cost of the relevant asset.

The cash flows are discounted using the Company’spre-tax long-term average weighted cost of capital rate. The unwinding of the discount is expensed as incurred and recognized in the statement of profit or loss. The estimated future costs of decommissioning are reviewed annually and adjusted as appropriate. Changes in the estimated future costs, or in the discount rate applied, are added to or deducted from the cost of the asset.

•

The estimated costs are recorded taking into account the present value of the obligation, discounted using the Company’spre-tax long-term average weighted cost of capital rate of 15.66% in 2018 (15.26% and 14.30% in 2017 and 2016, respectively).

•

Cost estimates are reviewed annually, with the consequent review of present value calculation, adjusting the amounts of assets and liabilities already accounted for.

Provisions(Continued)

Provisions for contingencies

The Company recognizes a provision for civil, labor and tax claims for those where likelihood of loss was assessed as probable by the legal advisors of the Company.

Assessment of the probability of loss includes an evaluation of available evidence, hierarchy of laws, available case laws, most recent court rulings and their relevance in the legal system, as well as the opinion of external legal counsel.

The provisions are periodically reviewed and adjusted to take into consideration changes in circumstances such as applicable statutes of limitation, conclusions of tax audits or additional exposures identified based on new issues or court decisions.

2.18.

Leases

Company as a lessee

The determination of whether an arrangement is (or contains) a lease is based on the substance of the arrangement at the inception of the lease.

A lease is classified at the inception date as a finance lease or operating leases.

A lease that transfers substantially all the risks and rewards incidental benefits relating to ownership to the Company is classified as a finance lease. Finance lease are capitalized at the inception of the lease at fair value of the leased property or, if lower, at the present value of minimum lease payments, with initial direct costs of the lessee being added to the asset, when applicable.

Finance lease payments are apportioned between finance charges and reduction of lease liability, so as to achieve a constant rate of interest on the remaining balance of the liability. Finance charges are recognized in the statement of profit or loss.

The leased assets are depreciated over their useful lives. However, when there is no reasonable certainty that the Company will obtain ownership by the end of lease term, the asset is depreciated over the shorter of its estimated useful life or the lease term.

Operating lease payments are recognized as an expense in the statement of profit or loss on a straight-line basis over the lease term.

Treasury shares

Treasury shares are equity instruments that are repurchased, recognized at cost, and deducted from equity. No gain or loss is recognized in the statements of profit or loss upon purchase, sale, issue or cancellation of Company’s own equity instruments. Any difference between carrying amount and consideration is recognized in other capital reserves.

2.20.

Basic and diluted earnings (loss) per share

Basic earnings (loss) per share are calculated by dividing profit or loss attributable to controlling shareholders by the weighted average number of common shares outstanding during the period.

The only potential instruments convertible into shares that would affect the diluted earnings (loss) per share refers to stock options granted to certain directors and employees.

2.21.

Significant accounting judgments, estimates and assumptions

The preparation of the Company’s consolidated financial statements requires management to make judgments, estimates and assumptions that affect the reported amounts revenues, expenses, assets and liabilities and the accompanying disclosures, and the disclosures of contingent liabilities.

Estimates and assumptions

The key assumptions concerning the future and other key sources of estimation uncertainty at the reporting date that have a significant risk of causing a material adjustment to carrying amounts of assets and liabilities within the next financial year, are described below.

The Company based its assumptions and estimates on information available when the consolidated financial statements were prepared. Existing circumstances and assumptions about future developments, however, may change due to market changes or circumstances arising that are beyond the control of the Company. Such changes are reflected in the assumptions when they occur.

Allowance for doubtful accounts

Trade receivables are recorded net of an allowance for doubtful accounts. The allowance for doubtful accounts is recorded based on IFRS 9 standard, which requires the Company to record expected credit losses on all its financial assets measured at amortized cost and at fair value through other comprehensive income, on either a12-month or lifetime basis, when applicable.

The Company perform an assessment monthly by segregating its financial assets based on their risk characteristics and counterpart, as follows: i) accounts receivable from private customers and ii) accounts receivable from public customers.

The Company applies the simplified approach and records lifetime expected losses on all its accounts receivable from customers. The Company updates the historical study of the behavior of the portfolio monthly and its risk matrix by age range on a monthly basis.

Further details can be found in Note 5.

Impairment ofnon-financial assets

Impairment exists when the carrying amount of an asset or cash-generating unit exceeds its recoverable amount, which is the higher of its fair value less cost to sell and its value in use. Fair value less cost to sell is calculated based on information available about similar assets sold or market prices less additional costs to dispose of the asset item. The calculation of value in use is based on discounted cash flow model, which does not include reorganization activities to which the Company has not yet committed or significant future investments that will improve the asset base of the object generating unit cash test. The recoverable amount is sensitive to the discount rate used in the discounted cash flow method, as well as expected future cash receipts and growth rate used for extrapolation purposes.

Provision for legal proceedings

Provisions are recorded for tax, civil and labor contingencies.

The provisions are periodically reviewed and adjusted to take into consideration changes in circumstances such as applicable statutes of limitation, conclusions of tax audits or additional exposures identified based on new issues or court decisions. Actual settlement of claims involving these estimates may result in amounts different from those estimated, due to the degree of judgment involved. The Company reviews its estimates and assumptions at least on an annual basis. Further details can be found in Note 20.

Provision for landfill closure

The Company recognized a decommissioning liability for landfill closure at the present value of expected costs to settle the obligation using estimated cash flows. In determining the fair value of the provision, assumptions and estimates are made in relation to discount rates, the expected cost for landfill closure and future maintenance of the site and the expected timing of those costs. Further details can be found in Note 19.

Tax

Deferred tax assets are recognized for all unused tax losses to the extent that it is probable that taxable profit will be available against which the losses can be used. Management’s significant judgment is required so as to determine the amount of deferred tax assets amount than can be recognized based upon the likely and level of future taxable profit, together with future tax planning strategies. Further details can be found in Note 22.

Fair value measurement of financial instruments

When the fair values of financial assets and financial liabilities recorded in the statement of financial position cannot be measured based on quoted prices in active markets, their fair value is measured using valuation techniques including the discounted cash flow (DCF) model. The inputs to these models are taken from observable markets where possible, but where this is not feasible, a degree of judgment is required in establishing fair values. Judgments include considerations of inputs such as liquidity risk, credit risk and volatility. Changes in assumptions relating to these factors could affect the reported fair value of financial instruments. See Note 30 for further disclosures.

Contingent consideration, resulting from business combinations, is valued at fair value at the acquisition date as part of the business combination. When the contingent consideration meets the definition of a financial liability, it is subsequently remeasured to fair value at each reporting date. The determination of the fair value is based on discounted cash flows.

Assets held for sale

On December 6, 2018, the Company and its Board of Directors approved the plan to sell shares on the Company´s Energy generation business, which has Enc Energy Brasil Participações S.A. (“Enc Energy”) as a minority shareholder, with 10% ownership. Negotiations with some investors were started and it is expected to be completed within one year. The Board of Directors considered the subsidiary to meet the criteria to be classified as held for sale at that date for the following reasons:

•

Companies’ from energy generation business are available for immediate sale and can be sold to the buyer in its current condition;

•

The actions to complete the sale were initiated and expected to be completed within one year from the date of the initial classification; and

•

A potential buyer has been identified and negotiations at the reporting date are at an advance stage.

New standards effective as of January 1, 2018

The Company applied IFRS 15 and IFRS 9 for the first time. The nature and effect of the changes as a result of adoption of these new standards are described below:

Several other amendments and interpretations apply for the first time in 2018, but do not have an impact on the consolidated financial statements of the Company. The Company has not early adopted any standards, interpretations or amendments that have been issued but are not yet effective.

IFRS 9 Financial Instruments (“IFRS 9”)

IFRS 9 replaces IAS 39 - Financial Instruments for annual periods beginning on or after January 1, 2018. IFRS 9 brings together all three aspects of the accounting financial instruments project: classification and measurement, impairment and hedge accounting. The Company applied IFRS 9 using the retrospective modified approach, with the initial application date of January 1, 2018.

The effect of adopting IFRS 9 is, as follows:

(a.1) Classification and measurement

Under IFRS 9, debt instruments are subsequently measured at fair value through profit or loss, amortized cost, or fair value through OCI. The classification is based on two criteria: the Company’s business model for managing the assets; and whether the instruments’ contractual cash flows represent ‘solely payments of principal and interest’ on the principal amount outstanding.

The assessment of the Company’s business model was made as of the date of initial application, January 1, 2018, and then applied retrospectively to those financial assets that were not derecognized before January 1, 2018. The assessment of whether contractual cash flows on debt instruments are solely comprised of principal and interest was made based on the facts and circumstances as at the initial recognition of the assets.

The classification and measurement requirements of IFRS 9 did not have a significant impact on the Company. The Company continued measuring at fair value all financial assets previously held at fair value under IAS 39. The following are the changes in the classification of the Company’s financial assets:

The change in carrying amount is a result of additional impairment allowance. See discussion on impairment below.

(a.2) Impairment

The adoption of IFRS 9 has fundamentally changed the Company’s accounting for impairment losses for financial assets by replacing IAS 39’s incurred loss approach with a forward-looking expected credit loss (ECL) approach. IFRS 9 requires the Company to recognize an allowance for ECLs for all debt instruments not held at fair value through profit or loss.

The Company performed an assessment by segregating its financial assets based on their risk characteristics and counterpart, as follows: i) accounts receivable from private customers and ii) accounts receivable from public customers.

(b.1)Variable consideration – significant financial component

Receivables from public sector customers

Generally, public sector customers pay after the due date, and in some cases, payments may be as late as a year or more.

In accordance with IFRS 15, the Company is required to determine whether there is a significant financing component in its contracts. According to paragraph 60 of this standard, in determining the transaction price an entity shall adjust the amount of the consideration promised for the effects of the time value of money when a significant financing component is present. A significant financing component may exist independently if the promise of financing is expressly stated in the contract or implied in the terms of payment agreed by the parties to the contract. The Company should analyze if the payment period agreed by the parties to the contract (expressly or implicitly) provides the client or the entity with a significant financial benefit from the transfer of goods or services to the customer.

Based on the above, the Company performed an analysis to identify the existence of a significant financial component for public sector clients, since the average term of effective receipt for this client portfolio is approximately six months. The Company considered the average rate of 8.50% p.a. for the discount rate of 2018 (8.40% at December 31, 2017), which represents the discount rate usually applied by the Company to calculate the present value of its non-current assets and liabilities. The IFRS 15 adoption adjustments reduced equity by R$503 at January 1, 2018.

The Company estimated that the effects of discounts and rebates amounted to R$1,948 at January 1, 2018, and made a corresponding adjustment in the equity statement.

In summary, the impact of the adoption of IFRS 15 was as follows:

Accounting standards and interpretations issued recently and not yet adopted by the Company

As of the date of the consolidated financial statements, the following issues and changes in IFRS and IFRICs had been published, but were not mandatory for the year ended December 31, 2018.

The Company has not early adopted any of the Standards below.

Based on the analyzes made so far, the Company estimates that the adoption of these standards, amendments and interpretations will not have a significant impact on the consolidated financial statements in the initial period of adoption, except for the effects of IFRS 16, as explained below.

IFRS 16 – Leases

IFRS 16 was issued in January 2016 and it replaces IAS 17 Leases, IFRIC 4 Determining whether an Arrangement contains a Lease, SIC-15 Operating Leases-Incentives and SIC-27 Evaluating the Substance of Transactions Involving the Legal Form of a Lease. IFRS 16 sets out the principles for the recognition, measurement, presentation and disclosure of leases and requires lessees to account for all leases under a single on-balance sheet model similar to the accounting for finance leases under IAS 17. The standard includes two recognition exemptions for lessees – leases of ‘low-value’ assets (e.g., personal computers) and short-term leases (i.e., leases with a lease term of 12 months or less). At the commencement date of a lease, a lessee will recognize a liability to make lease payments (i.e., the lease liability) and an asset representing the right to use the underlying asset during the lease term (i.e., the right-of-use asset). Lessees will be required to separately recognize the interest expense on the lease liability and the depreciation expense on the right-of-use asset.

IFRS 16, which is effective for annual periods beginning on or after January 1, 2019, requires lessees and lessors to make more extensive disclosures than under IAS 17.

Accounting standards and interpretations issued recently and not yet adopted by the Company

IFRS 16 – Leases (Continued)

The Company plans to adopt IFRS 16 using the retrospective modified transition method.

On January 1, 2019, the Company recognized a right to use asset and a lease liability of R$ 23,264.

IFRIC 23 – Uncertainty about treatment of taxes on profit

The new interpretation establishes requirements for recognition and measurement in situations where the Company has defined during the process of calculating income taxes (income and social contribution taxes) the use of tax treatments that may be classified as uncertain and, therefore, may be questioned by the tax authority. This interpretation is effective for fiscal years beginning on or after January 1, 2019.

In the evaluation of the Company’s Management, no significant impacts are expected as a result of the interpretation, since all the procedures adopted for the determination and collection of taxes on profit are supported by the legislation and precedents of Administrative and Judicial Courts.

3.	Capital and financial risk management

The Company’s main objectives when managing capital are to safeguard its ability to continue as a going-concern, to provide returns to shareholders and maximize shareholder value, provide better cash management to ensure availability of credit lines in order to maintain liquidity, and obtain funds at the lowest cost possible.

As of December 31, 2018, the Company recorded negative working capital (calculated as total current assets minus total current liabilities) of R$1,289.8 million and a capital deficiency (corresponding to total assets minus total liabilities) of R$1,149.2 million (working capital of R$293.4 million and a capital deficiency of R$455.9 million as of December 31, 2017).

Furthermore, Management has identified several significant obligations arising during 2019 that require funding through liquidity, primarily relating to (a) the payments required to make for severance and other demobilization costs related to discontinued operations and (b) capital expenditures required in connection with contract renewals.

The Company´s Management is engaged in efforts to generate liquidity in order to improve the liquidity position and fund their obligations, including negotiations in respect of the sale of certain assets, which sales will likely require the approval of the holders of our Debt Instruments.

In addition, the Company, with the approval of its Board of Directors, has initiated negotiations with the holders of the Debt Instruments, as well as other relevant creditors, with the goal of restructuring its financial and such other debt. In that regard, the Company engaged an outside restructuring advisor as well as outside legal counsel to advise in connection with a potential debt restructuring process. The Company is currently seeking to conclude the debt restructuring process in the course of 2019.

There can be no assurance that the debt restructuring process will be successful or that we will be able to generate sufficient liquidity in order to fully address our liquidity concerns. Our inability to significantly improve our liquidity position and comply with our financial covenants and other payment obligations could have a material adverse effect on us and result in a judicial or judicial reorganization process, which may result in our shareholders losing their entire investment.

There were no changes in the objectives, policies or processes for managing capital during the years ended December 31, 2018 and 2017.

Impairment test for cash generating units

A cash generating unit (“CGU”) is defined as the smallest identifiable group of assets that generates cash inflows that are largely independent of the cash inflows from other assets or groups of assets. Historically, the acquisitions that generated such goodwill balances were mainly related to the expansion and development of business in different regions, such as the acquisition of Resicontrol, with operations in the city of Tremembé, CTR Itaboraí, with operations in Rio de Janeiro state, Grupo Viva, with operations in the states of Bahia and Alagoas, and Grupo GeoVision, in the city of Ribeirão Preto.

The operation and cash generation of such CGUs is directly related to the services rendered on each geographical region that consist in an integrated operation and, as such, are tested for impairment as separate CGUs, considering the geographical aspect inherent to the respective service and the lack of interrelation and synergies among the operations for the different CGUs.

During 2018, the waste collection business of Estre presented a rapid deterioration, mainly due to the market conditions including strong margins compression. These declining margins makes this business unattractive to renew some of the collection contracts. Since the Company does not expect a recovery of the market conditions in the future, the Company decided to exit gradually from this market segment and such strategy was reflected in the estimated future cash flow used for impairment testing, which resulted in impairment losses recognized in 2018.

The recoverable amount of the cash generating units shown above was computed based on the calculation of the value in use, considering cash flow projections from financial budgets approved by the board of directors, discounted to present value.

Considerations for the calculation of value in use:

Currency: Brazilian Reais (BRL);

Direct taxes: taxes on gross revenue applicable to the Company’s operations were considered;

Financial projections are presented in nominal terms, i.e., considering the estimated inflation over the projected period;

Discount rate: calculated according to the WACC (Weighted Average Cost of Capital) methodology, after income taxes; and

Projections: budget prepared by Company and approved by the Board of Directors.

Main assumptions used on the calculation of the value in use

•

Revenue Growth: is based on the observation of the historical behavior of each revenue line, as well as trends based on market analysis. For the collection segment, we considered we will keep the actual contracts until its expiration, with margins as the current ones, as per business strategy as described above.

•

EBITDA: it takes into account the historical margin, estimate of price correction, as well as the projects in progress with the objective of greater cost efficiency and revenue growth.

Perpetuity growth rate, not applicable for collection segment contracts, given recent market dynamics, the Company does not take into consideration their renewal any longer, after the cash flow calculation period on the long term view:

The Perpetuity rate was obtained considering the follow assumptions:

Long term inflation (IPCA); and

Increase in population and consequent volume of disposals.

The discount rate is calculated using the WACC (Weighted Average Cost of Capital) methodology, before income taxes. The WACC is the rate that a company is expected to pay on average to all its security holders to finance its assets. The WACC is commonly referred to as the firm’s cost of capital. The WACC represents the minimum return that a company must earn on an existing asset base to satisfy its creditors, owners, and other providers of capital, or they will invest elsewhere. Companies raise money from a number of sources: common stock, preferred stock, straight debt, convertible debt, exchangeable debt, warrants, options, pension liabilities, executive stock options, governmental subsidies, and so on. Different securities, which represent different sources of finance, are expected to generate different returns. The WACC is calculated taking into account the relative weights of each component of the capital structure. The more complex the company’s capital structure, the more laborious it is to calculate the WACC.

Inflation (IPCA)

Inflation was estimated considering inflation forecasts released by the main financial institutions of Brazil. The Brazilian Central Bank use to publish a research called Market Readout. On the Brazilian Central Bank Website we can find the complete long term forecast for several economic financial indicators.

From the total amount of R$547,689 related to the impairment for the fiscal year 2018, showed above, R$485,314 was recorded as an impairment of the goodwill, and R$62,375 was recorded as an impairment of Others Intangibles and PP&E (please refer to Notes 11 and 12).

Sensitivity analysis

For the sensitive analysis of goodwill impairment, the Company considered the following variations (increases / decreases), expressed in percentage points (p.p) for the year ended December 31, 2018:

•

Increase in 0.5 p.p on the discount rate

•

Decrease in 1.0 p.p on the EBITDA margin for all periods projected, including in perpetuity

•

Decrease in 0.5 p.p on the growth rate in perpetuity

Except for the CGUs for which an impairment loss was recognized in 2018, the sensitivity analysis indicated that the recoverable amount for these CGUs would continue to be higher than its corresponding carrying amount. For the CGUs for which an impairment loss was recognized in 2018 the sensitivity analysis resulted in further impairment.

1^stissue of debentures

On June 27, 2011, the Company conducted its 1^st issue of unsecured, subordinated debentures, not convertible into shares, with collateral and additional personal guarantee, for public distribution with restricted placement efforts, for the issue of 2,720 debentures, with a face value of R$250, fully paid by Banco BTG Pactual S.A., with semi-annual payments starting of September 2013 and final maturity on March 9, 2017.

The proceeds from the issue of these debentures were used to settle loans outstanding from Banco BTG Pactual.

In December 2012, the Company debenture holders agreed to adjust the interest rate to be charge in new issuances. Such interest rate was reduced and it is based on the CDI rate plus 2.95% spread per year.

During the years 2013 to 2016, the Company renegotiated the portions of principal maturing in September 2013, March 2014, September 2014, March 2015, September 2015, March 2016 and September 2016, which would be paid together with the remaining installments.

The debentures provide for accelerated maturity clauses should the following events take place: (i) corporate transactions (merger,spin-off, etc.) carried out by the Company and its subsidiaries; (ii) disclosure of financial information; (iii) default in connection with transactions carried out with financial institutions; (iv) failure to meet financial ratios set forth in the transaction’s contractual terms; (v) payment of dividends and/or interest on equity exceeding R$45,000 and (vi) assets disposed of or given in guarantee to third parties whose individual or combined amounts exceed R$25,000.

1^stissue of debentures (Continued)

On August 10, 2017, Estre entered into a binding facility commitment letter with the holders of the debentures and related debt acknowledgment instrument, which provided for the restructuring of the existing debentures and related debt acknowledgment instrument through the prepayment of US$200 million, a partial debt write-down and the restructuring of the existing debentures. On December 7, 2017, Estre amended the binding facility commitment letter, pursuant to which the creditors agreed to amend the required prepayment to a defined range of the repayment of a minimum debt prepayment of US$100 million and a maximum debt prepayment of US$200 million.

On December 21, 2017, Estre completed the debt restructuring and prepaid R$199,086 of the outstanding amount. In addition, the debenture holders granted a haircut for an amount of R$49,772, corresponding to 25% of the prepaid amount. Such haircut was recorded as finance income.

As a result of the restructuring above, the outstanding debentures and related debt acknowledgment instrument bear interest at a rate of CDI plus 2.0% per annum, with payments of principal to be repaid semi-annually in 11 installments after a three-year grace period and maturing in 8 years. Interest is payable semi-annually after a grace period of two years on the debenture outstanding balance plus monthly compounded interest accrued over the first 18 months.

IFRS 9 requires that a substantial modification of the terms of an existing financial liability, or a part of it, should be accounted for as an extinguishment of the original financial liability and the recognition of a new financial liability. The Company concluded that the net present value of the cash flows under the new terms of the refinanced debt, discounted at the original effective interest rate was below a 10% difference compared to the discounted present value of the remaining cash flows of the original debt instrument, therefore, the Company accounted for the debt restructuring as a debt modification.

(b)

2^nd issue of debentures

On December 14, 2012, the Company completed its second issue of unsecured debentures, not convertible into shares, with collateral and additional personal guarantee, for public distribution with restricted placement efforts, for the issue of 3,000 debentures with a face value of R$250. The actual issuance was for 2,600 debentures. The debentures mature in five years and bear interest at the CDI rate plus of 2.60% p.a. Principal would be repaid semiannually, in seven installments beginning in December 2014.

In 2015 and 2016, the Company renegotiated installments maturing June 2015, December 2015, June 2016 and December 2016, with payment in 2017.

The proceeds from the issue of the debentures were used to settle bank loans, to extend the debt maturities in working capital.

The debentures provides for accelerated maturity clauses should the following events take place: (i) corporate transactions (merger,spin-off etc.) carried out by the Company and its subsidiaries; (ii) disclosure of financial information; (iii) default in connection with transactions carried out with financial institutions; (iv) failure to comply with financial ratios set forth in the transaction’s contractual terms; (v) payment of dividends and/or interest on equity exceeding R$30,000 and (vi) assets disposed of or given in guarantee to third parties whose individual or combined amounts exceed R$100,000. As of December 31, 2016 and 2015, the Company failed to comply with the covenants relating to the maintenance of certain financial ratios as well as failed to meet the principal repayment schedule. As of December 31, 2016 and 2015, the Company had not obtained the waiver of debenture holders therefore the debentures were included as liabilities in the statement of financial position.

On August 10, 2017, Estre entered into a binding facility commitment letter with the holders of the debentures (1st and 2nd issuances) and related debt acknowledgment instrument, which provided for the restructuring of the existing debentures and related debt acknowledgment instrument through the prepayment of US$200 million, a partial debt write-down and the restructuring of the existing debentures.

Covenants

According to the Company’s debenture agreements, the following financial indices must be calculated and presented by the Company’s management, semi-annually on June 30 and December 31 of each year, as from December 31, 2018:

(a) the quotient of the division of Net Debt by EBITDA shall be equal to or lower than the following indices based on the Company’s consolidated financial statements for the following fiscal years:

Net Debt / EBITDA

December 31, 2018 - 4.0x

December 31, 2019 and subsequent fiscal years - 3.5x

(b) from December 31, 2019 (inclusive), for three consecutive semesters, the ratio of the Net Debt division to EBITDA should not exceed 3.0x;

(c) the Debt Service Coverage Ratio shall be equal to or greater than 1.2x if the Net Debt / EBITDA ratio is greater than 2.8x and shall be equal to or greater than 1.0x if the ratio of Net Debt / EBITDA is equal to or lower than 2.8x.

As a result of the liquidity constraints identified by management, the Company was not able to maintain financial covenants clauses included on its Debt Instruments for the year ended on December 31, 2018, and the total debt was reclassified and presented as a current liability. Based on this fact, the Company and its Board of Directors has decided to initiate negotiations with the holders of its Debt Instruments with the goal of restructuring its financial debt. The Company engaged a restructuring firm as well as outside legal counsel to advise in connection with a debt restructuring process. The Company currently expects to conclude the debt restructuring during 2019.

(a)

PIS and COFINS are taxes levied by the Brazilian federal government on gross revenues. The standard rates are 7.60% for PIS and 1.65% for COFINS applicable to entities declaring income tax and social contribution on the ‘actual profits’ basis. These amounts are invoiced to and collected from our customers and recognized as deductions to gross revenue (Note 23) against Tax liabilities, as we are acting as agents collecting these taxes on behalf of the government. PIS and COFINS taxes paid on certain purchases may be claimed back as tax credits to offset PIS and COFINS payable. These amounts are recognized as Taxes recoverable (Note 6) and on a monthly basis are offset against PIS and COFINS Tax payable, and presented net as the amounts are due to the same tax authority. Brazilian tax legislation allows smaller entities with less than R$78 million in annual gross revenues to opt to declare income taxes on the ‘presumed profits’ basis. These are subject to lower COFINS and PIS rates of 3.00% and 0.65%, respectively. However, PIS and COFINS taxes on purchases may not be claimed back and will not generate tax credits under the presumed profits basis.

(b)

ISS is a tax levied by municipalities on revenues from the provision of services. ISS tax is added to amounts invoiced to our customers for the services we render. These are recognized as deductions to gross revenue (Note 23—Taxes levied—ISSQN) against Tax liabilities, as we are acting as agents collecting these taxes on behalf of municipal governments. The rates may vary from 2.00% to 5.00%, however most of the municipalities in which we operate levy ISS at the higher rate. Each municipality sets slightly different rules regarding the use of credits and withholding of ISS tax on payments to suppliers.

(c)

IRPJ and CSLL are corporate income taxes levied by the Brazilian federal government. The IRPJ rate is 25% and the CSLL rate is 9%, resulting in a combined federal corporate income tax rate of 34% on taxable profits. The expense for current income tax is recognized in the statement of profit or loss under ‘Current income and social contribution taxes’ against tax payable. However, for some entities in the group, advances for the payment of income tax are paid on a quarterly basis during the tax year and are recognized as an asset under Taxes recoverable (Note 6—‘Corporate income tax (IRPJ)’ and ‘Social contribution tax on net profit (CSLL)’). Income tax is levied on legal entities individually, with no right of offset between entities in a group. Smaller entities opting to declare income taxes on the ‘presumed profits’ basis are taxed at the same rates on a ‘presumed profit’ of 32% of gross revenues.

(d)

Purchases of certain materials or services require us to retain and pay taxes on behalf of our suppliers. The rate of 4.65% in relation to PIS, COFINS and CSLL tax on applicable purchases is withheld from payments made to suppliers and recognized as a tax liability, with no impact to the statement of profit or loss.

(e)

Refers to installment payment of IRPJ, CSLL, PIS and COFINS, which payment is deferred in 30 to 60 installments, adjusted by the SELIC rate. The accrual of interest on this liability is recognized as a financial expense under the line item—‘Interest for late payment of taxes’ (Note 28).

(f)

PRT - payment of 24% in 24 installments, residual not contemplated by use of damages will be paid in 60 months, according to MP n ° 766 of April 4, January 2017. The taxes included in the PRT are as follows: PIS/COFINS, CSLL, IRPJ and IRRF.

(g)

PERT - installment of unpaid taxes and IOF, modality does not include use of impairment, installment in 120 months, according to MP nº 783 of May 31, 2017. The taxes included in the PERT are as follows: PIS/COFINS and IOF.

(h)

Refers mainly to ISS payable to the Paulínia City Government in 36 installments, not subject to inflation adjustment or interest. (installments of ISS of the cities of São Paulo, Paulínia, Itapevi and Maceió, plots range from 24 to 120).

(i)

In August 2014, enactment of Federal Law No. 12,996/2014 (‘‘REFIS da Copa’’) enabled the inclusion of new tax contingencies in REFIS (tax installment payment program). The Company initially included the overdue taxes in REFIS da Copa in order to benefit from interest and fine amnesty. With the launch of PERT in 2017, the Company decided to include most part of taxes in this new program, instead of REFIS da Copa.

(j)

INSS is a social security charge levied on wages paid to employees. On certain purchases of services we are required to withhold 11% of the amounts billed by our suppliers and pay INSS tax on their behalf, with no impact to the statement of profit or loss.

(k)

On certain purchases of services we are required to withhold 1.5% of the amounts billed by our suppliers and pay IRPJ (Income tax) on their behalf, with no impact to the statement of profit or loss.

2017 Tax Amnesty Program

On May 31, 2017, the Company joined a tax amnesty program (the “2017 Program”), under which the Company settled the payment of certain unpaid overdue taxes and tax contingencies, including some which were in litigation, through November 30, 2016, including interest and fines.

The 2017 Program allowed for the use of unused tax loss carry forward to settle the tax liability under the program. As a result, the Company recognized a deferred tax asset related to the tax loss carry forwards that was used to settle the tax liability under the program and which the Company did no previously recognized. In addition, the Company recognized a tax liability as follows:

The balance of R$ 159,611 would be paid as follows:

•

R$ 125,415 in 24 installment payments; and

•

R$ 34,196 in 60 installment payments.

Share-based payment reserve

On September 15, 2015, Estre Brazil’s Board of Directors approved at the Special General Shareholders’ Meeting, the granting of a stock option plan to certain directors and employees and the total number of options granted under the plan. The options vest in 3 tranches, subject to the following vesting conditions:

(iii)

At the third anniversary of the date on which the employee becomes a manager or employee of the Company, the remaining 33% of the options will vest and may be exercised.

Angra Put Option Rights

In 2011, the Company’s shareholders entered into a shareholders agreement (the ‘‘Estre Shareholders’ Agreement’’) under which Angra was granted a put option on Estre Brazil shares owned by Angra, which could be exercised in the event its interest in Estre Brazil was diluted to a holding of less than 5%, due to a capital contribution or other events described in the agreement. The option price was the fair market value of the Company shares and payable within 6 months after the exercise of the put option, adjusted for inflation (IPCA) plus 9.5% per year.

On March 6, 2018, Angra exercised the put option, and the Company will acquire the Estre Brazil shares held by Angra for an amount of approximately R$37,606 payable until September 6, 2018.

As of December 31, 2018, the Company recorded a liability at fair value for an amount of R$41,662 (R$37,884 at December 31, 2017). We have not yet made any payments to Angra due to liquidity constraints, which constitutes a default under the Share Put Option Agreement entered into with Angra. The Company is in ongoing negotiations with Angra regarding the terms for the payment of amounts owed to them and there are no assurances that we will be successful in these negotiations, and Angra has reserved all other rights, remedies, actions and powers to which it may be entitled. As a result, Angra may seek certain remedies afforded to them under the Share Put Option Agreement and otherwise under Brazilian law, including the enforcement of their security interest of 4.38% of the share capital of the Estre Ambiental S.A. For these reasons, the Company believes that it may be required to also include this debt as part of the debt restructuring efforts.

As mentioned in Note 17, the Company was benefitted by reduction of part of the interest and fines arising from taxes (included in the PRT and PERT tax amnesty programs). The benefit was calculated based on the tax loss, and therefore a credit was recorded in deferred income tax, in profit or loss, against a reduction in the tax payable balance (included in the REFIS).

Segment reporting

Business segment information is presented according to management’s definition of the operational management framework and based on the reports used by the Company’s chief operating decision makers.

Management separately monitors operating income (loss) of business units in order to make decisions on resource allocation and performance assessment. Information on the business only considers transactions and balances directly attributable to the segments, and that can be allocated on a reasonable basis, and, as such, are restricted to the calculation of operating income (expenses) before financial income (expenses), not including assets and liabilities, financial income and expenses, and income and social contribution taxes.

The Company’s financing (including financing income and expenses) and income taxes are managed at the corporate level, and are not allocated to operating segments.

Revenue from inter-segment sales is eliminated upon consolidation and reflected in the column “Eliminations.”

The Company has the following segments:

Collection & Cleaning Services: includes industrial collection from large businesses and local household collection, transportation and temporary storage for environmental liability emergencies, industrial accidents and preparation of waste for final disposal. Logistical planning is performed to reduce the risks and environmental impacts involved in internal and external transportation of waste to its final destination.

O&G: soil treatment and restoration services throughout Brazil, and cleaning of storage tanks for the oil & gas industry.

Landfill: services provided by treatment and waste disposal centers, such as ground sealing, drainage and treatment of percolated liquid (leachate), rainwater catchment and soil treatment with hydrocarbons.

Credit risk (Continued)

Customer credit risk is managed by each business unit, subject to the procedures, policies and controls established by the Company in relation to this risk. Invoices are issued only after formal approval is given by the customer.

Management monitors the risk involved and adopts necessary measures and procedures, in addition to recording an allowance for doubtful accounts as appropriate.

ii)

Interest rate risk

Such risk arises from the Company’s exposure to fluctuations in interest rates on its financial assets and liabilities. In order to mitigate this risk, the Company seeks to raise funds subject to fixed or floating rates.

The Company is exposed to risks of interest rate fluctuations on its investments, accounts payable for acquisition of investments, loans and financing and debentures.

The Company conducted sensitivity analyses of the interest rate risks to which its financial instruments are exposed. For the analysis of sensitivity to changes in interest rates, management adopted as probable scenario the future interest rates according to quotations obtained from BM&FBOVESPA of 6.72% for CDI and to 6,98% for TJLP. Scenarios II and III were estimated with an increase of 25% and 50%, respectively, whereas scenarios IV and V estimate an additional decrease of 25% and 50%, respectively, of the rates in the probable scenario.

The following table shows the possible impacts on profit or loss in each scenarios for 2018:

In order to manage cash liquidity, assumptions are established regarding future payables or receivables, and are daily monitored by the Treasury department.

The Company’s exposure to liquidity risk is as follows:
