Opinions on the financial statements and internal control over financial reporting
We have audited the accompanying consolidated balance sheets of Suzano S.A. and its subsidiaries (the "Company") as of December 31, 2024 and 2023, and the related consolidated statements of income (loss), comprehensive income (loss), changes in equity and cash flow for each of the three years in the period ended December 31, 2024, including the related notes (collectively referred to as the "consolidated financial statements"). We also have audited the Company’s internal control over financial reporting as of December 31, 2024, based on criteria established in Internal Control - Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO).
In our opinion, the consolidated financial statements referred to above present fairly, in all material respects, the financial position of the Company as of December 31, 2024 and 2023, and the results of its operations and its cash flows for each of the three years in the period ended December 31, 2024 in conformity with International Financial Reporting Standards as issued by the International Accounting Standards Board. Also in our opinion, the Company maintained, in all material respects, effective internal control over financial reporting as of December 31, 2024, based on criteria established in Internal Control - Integrated Framework (2013) issued by the COSO.
Basis for opinions
The Company’s management is responsible for these consolidated financial statements, for maintaining effective internal control over financial reporting, and for its assessment of the effectiveness of internal control over financial reporting, included in the accompanying Management’s Report on Internal Control over Financial Reporting. Our responsibility is to express opinions on the Company’s consolidated financial statements and on the Company’s internal control over financial reporting based on our audits. We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) (PCAOB) and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.
We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audits to obtain reasonable assurance about whether the consolidated financial statements are free of material misstatement, whether due to error or fraud, and whether effective internal control over financial reporting was maintained in all material respects.
Our audits of the consolidated financial statements included performing procedures to assess the risks of material misstatement of the consolidated financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the consolidated financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the consolidated financial statements. Our audit of internal control over financial reporting included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, and testing and evaluating the design and operating effectiveness of internal control based on the assessed risk. Our audits also included performing such other procedures as we considered necessary in the circumstances. We believe that our audits provide a reasonable basis for our opinions.
Definition and limitations of internal control over financial reporting
A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company's internal control over financial reporting includes those policies and procedures that (i) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (ii) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (iii) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company’s assets that could have a material effect on the financial statements.
Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.
Critical audit matters
The critical audit matters communicated below are matters arising from the current period audit of the consolidated financial statements that were communicated or required to be communicated to the audit committee and that (i) relate to accounts or disclosures that are material to the consolidated financial statements and (ii) involved our especially challenging, subjective, or complex judgments. The communication of critical audit matters does not alter in any way our opinion on the consolidated financial statements, taken as a whole, and we are not, by communicating the critical audit matters below, providing separate opinions on the critical audit matters or on the accounts or disclosures to which they relate.
Valuation of biological assets
As described in Notes 3.2.15 and 13 to the consolidated financial statements, the Company’s consolidated biological assets balance as of December 31, 2024, of R$ 22,283,001 thousand, are measured at fair value less costs necessary to prepare the assets for their intended use or sale. The fair value is estimated by management using a discounted cash flow model. Management’s cash flow projections included significant judgments and assumptions including average sale price of eucalyptus in different regions and the average annual forests growth (IMA) of biological assets.
The principal considerations for our determination that performing procedures relating to the valuation of biological assets is a critical audit matter are (i) there was a high degree of auditor subjectivity in applying our procedures relating to the fair value measurement of the biological assets due to the significant amount of judgment required by management when developing these estimates; (ii) significant audit effort was required in assessing the significant assumptions relating to average annual forests growth (IMA) and average sale price of eucalyptus in different regions; and (iii) professionals with specialized skill and knowledge were used to assist in performing these procedures and evaluating the audit evidence obtained regarding the estimated discount cash flow model and discount rate.
Addressing the matter involved performing procedures and evaluating audit evidence in connection with forming our overall opinion on the consolidated financial statements. These procedures included testing the effectiveness of controls relating to the completeness of data and the model used to measure the fair value of the biological assets. Our procedures also included testing management’s process for developing the fair value estimate; evaluating the appropriateness of the discounted cash flow model; testing the completeness, accuracy, and relevance of underlying data used in the model; and evaluating the significant assumptions used by management, related to the average annual forests growth (IMA) and the average eucalyptus
sale price. In evaluating management’s assumptions relating to average annual forests growth (IMA) and average eucalyptus sale price involved evaluating whether the assumptions used by management were reasonable considering; (i) the consistency with external market and industry data; (ii) whether these assumptions were consistent with evidence obtained in other areas of the audit and (iii) the disclosure requirements established by the accounting standard were met. Professionals with specialized skill and knowledge were used to assist in the evaluation of the Company’s discounted cash flow model and the discount rate.
Tax and social security judicial liabilities and uncertainty over income tax treatments
As described in Notes 3.2.19, 3.2.22 and 20 to the consolidated financial statements, as of December 31, 2024, the Company’s consolidated provision for judicial liabilities relating to tax and social security of R$ 2,335,662 thousand (net of judicial deposits) and discloses those that are not probable that a loss will be incurred , in the total amount of R$ 9,837,082 thousand. The Company recognizes liabilities in the consolidated financial statements for the resolution of pending litigation when management determines that a loss is probable, and the amount of the loss can be reasonably estimated. No liability for an estimated loss is accrued in the consolidated financial statements for unfavorable outcomes when, after assessing the information available, (i) management concludes that it is not probable that a loss will be incurred in any of the pending litigation; or (ii) management is unable to estimate the loss for any of the pending matters.
The principal considerations for determining that performing procedures relating to judicial liabilities relating to tax, social security and uncertainty over income tax treatments is a critical audit matter are (i) the use of significant judgment by management when assessing the likelihood of a loss being incurred; and (ii) when determining whether a reasonable estimate of the loss for each claim can be made, which in turn led to a high degree of auditor judgment and effort in evaluating management’s assessment of the loss contingencies associated with litigation claims.
Addressing the matter involved performing procedures and evaluating audit evidence in connection with forming our overall opinion on the consolidated financial statements. These procedures included testing the effectiveness of controls relating to management’s evaluation of tax, social security litigation claims and uncertainty over income tax treatments, including controls over determining whether a loss is probable and whether the amount of loss can be reasonably estimated. These procedures also included, among others, obtaining and evaluating the letters of audit inquiry with internal and external legal counsel, evaluating the reasonableness of management’s assessment regarding whether an unfavorable outcome is reasonably possible or probable and reasonably estimable, and evaluating the sufficiency of the Company’s litigation contingency disclosures. Professionals with specialized skill and knowledge were used to assist in the evaluation of the likelihood of loss being incurred.
