**Management's Report on Internal Control over Financial Reporting**

The management of Suzano S.A. and subsidiaries (the "Company") is responsible for establishing and maintaining adequate internal control over financial reporting and for its assessment of the effectiveness of internal control over financial reporting.

The Company's internal control over financial reporting is a process designed by, or under the supervision of, the principal executive and principal financial officers, or persons performing similar functions, and effected by the Company's Statutory Audit Committee, the Company's Board of Directors, management, and other personnel to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with and in compliance with the International Financial Reporting Standards as issued by the International Accounting Standards Board. The Company's internal control over financial reporting includes those policies and procedures that (a) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the Company; (b) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with and in compliance with the International Financial Reporting Standards as issued by the International Accounting Standards Board, and that receipts and expenditures of the Company are being made only in accordance with authorizations of management and directors of the Company; and (c) 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 consolidated 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.

The effectiveness of the Company's internal control over financial reporting as of December 31, 2025, is based on the criteria established in Internal Control - Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO). Based on that assessment, management has concluded that, as of December 31, 2025, the Company's internal control over financial reporting is effective.

PricewaterhouseCoopers Auditores Independentes Ltda., an independent registered public accounting firm, has audited the effectiveness of the Company's internal control over financial reporting as stated in their report as of December 31, 2025, which is included herein.

## Exhibit 99.3

**Report of independent registered public accounting firm**

To the Board of Directors and Shareholders of Suzano S.A.

***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, 2025 and 2024, and the related consolidated statements of income (loss), comprehensive income (loss), changes in equity and cash flows for each of the three years in the period ended December 31, 2025, 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, 2025, 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, 2025 and 2024, and the results of its operations and its cash flows for each of the three years in the period ended December 31, 2025 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, 2025, 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 3.2.8 and 13 to the consolidated financial statements, the Company's consolidated biological assets balance as of December 31, 2025, of R$26,097,164 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 gross selling 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 gross selling 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, the average annual forests growth (IMA) 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 gross selling price of eucalyptus. In evaluating management's assumptions relating to average annual forests growth (IMA) and average gross selling price of eucalyptus 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 3.2.12, 3.2.13 and 20 to the consolidated financial statements, as of December 31, 2025, the Company's consolidated provision for judicial liabilities relating to tax and social security of R$2,270,733 thousand (net of judicial deposits) and discloses those that are not probable that a loss will be incurred , in the total amount of R$10,417,734 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.

**2 BASIS OF PREPARATION AND PRESENTATION OF FINANCIAL STATEMENTS**

The Company's consolidated financial statements have been prepared in compliance with the International Financial Reporting Standards as issued by the International Accounting Standards Board ("IFRS Accounting Standards") and disclose all the applicable significant information related to the financial statements, which is consistent with the information used by Management in the performance of its duties.

The Company's consolidated financial statements are expressed in thousands of Brazilian Reais ("R$") and disclosures of amounts in other currencies, when applicable, were also expressed in thousands, unless otherwise stated.

The preparation of consolidated financial statements requires Management to make judgments, use estimates and adopt policies in the process of applying accounting practices that affect the disclosed amounts of revenues, expenses, assets and liabilities, including the disclosure of contingent liabilities assumed. However, the uncertainty inherent to these judgements, assumptions and estimates could result in material adjustments to the carrying amount of certain assets and liabilities in future periods. The accounting practices requiring a higher level of judgment, and those which are more complex, as well as areas in which assumptions and estimates are significant, are disclosed in Note 3.2.19.

The consolidated financial statements were prepared on a historical costs basis, considering the historical cost as a value basis and adjusted to reflect the attributed cost of land and buildings on the date of transition to IFRS Accounting Standards, except for the following material items recognized:

&nbsp;&nbsp;&nbsp;&nbsp;(i)Derivative and non-derivative financial instruments measured at fair value;

&nbsp;&nbsp;&nbsp;&nbsp;(ii)Share-based payments and employee benefits measured at fair value; and

&nbsp;&nbsp;&nbsp;&nbsp;(iii)Biological assets measured at fair value;

The material accounting policies applied to the preparation of these consolidated financial statements are presented in Note 3.

The consolidated financial statements were prepared under the going concern assumption.

**3 SUMMARY OF MATERIAL ACCOUNTING POLICIES**

The accounting policies have been consistently applied to all consolidated companies.

There were no changes on such policies and estimates calculation methodologies, except for the application of the new accounting policies presented in note 3.1, adopted as of January 1, 2025.

**3.1 New accounting policies and changes in accounting policies adopted**

The new standards and interpretations issued, until the issuance of the Company's consolidated financial statements, are described below.

**3.1.1 Amendments to IAS 21: Lack of interchangeability (applicable for annual on/or after January 1, 2025)**

The changes will create requirements for the entity to apply a consistent approach to assessing whether a currency is exchangeable for another currency and, when it is not, to determining the appropriate exchange rate to use and the disclosures to be made.

In this context, exchangeability is considered non-existent when, for a given purpose, the entity is unable to obtain more than an insignificant amount of foreign currency. To this end, the entity evaluates:

&nbsp;&nbsp;&nbsp;&nbsp;i.the timeliness of obtaining foreign currency;

&nbsp;&nbsp;&nbsp;&nbsp;ii.the practical ability (and not the intention) to obtain foreign currency; It is

&nbsp;&nbsp;&nbsp;&nbsp;iii.the available markets or exchange mechanisms that create enforceable rights and obligations.

The Company assessed the content of this pronouncement and did not identify any impacts.

**3.2 Accounting policies adopted**

The standards and interpretations issued up to the date of the Company's consolidated financial statements are described below.

**3.2.1 Financial statements**

**3.2.1.1 Consolidated financial statements**

They are prepared using information from Suzano and its subsidiaries on the same base date, except for the subsidiary Suzano Packaging and the affiliates Biomas, Simplifyber, which have a lag of less than three months in relation to the base date of these financial statements, in accordance with the provisions of IAS 28. The Company evaluates the effects of timing differences and incorporates the impact of relevant events into the consolidated results. As of December 31, 2025, no material transactions were identified that would affect the financial position presented in the financial statements

On December 31, 2025, Suzano had an investment in the associate Spinnova, in the amount of R$54,393, representing 18.76% of the equity of this associate. Up to the date of this report, the latest financial statements published for this investment were more than three months out of date. In these circumstances, the investment is measured based on the latest information available, with the necessary adjustments being made as a result of the effects of significant transactions and events, which have no material effect on the consolidated result.

The Company consolidates all subsidiaries over which it has direct or indirect control, i.e. when it is exposed to or has the right to variable returns on its investment with the investee and has the ability to direct the relevant activities of the investee. When applicable, the participation of non-controlling shareholders is disclosed separately.

In addition, all transactions and balances between Suzano and its subsidiaries, associates and joint operations were eliminated in consolidation, as well as the unrealized profits or losses arising from these transactions, net of tax effects, investments and the respective equity results.

**3.2.2 Investments**

**3.2.2.1 Subsidiaries**

These include all entities for which the Company has the power to govern the financial and operating policies, generally through a majority of voting rights. The Company controls an entity when the Company is exposed to, or has rights to, variable returns on its investment in the investee, and has the ability to affect those returns through its power over the entity.

Subsidiaries are consolidated from the date on which control is obtained and consolidated from the date on which control ceases.

**3.2.2.2 Joint operations**

These include all entities for which the Company maintains contractually established control over its economic activity, and exists only when the strategic, financial and operational decisions regarding the activity requiring the unanimous consent of the parties sharing control.

In the consolidated financial statements, the balance of assets, liabilities, revenue and expenses are recognized proportionally to the interest in joint operations.

**3.2.2.3 Associates and joint ventures**

In the investments in associates, the Company must have significant influence, which means the power to participate in the financial and operating policy decisions of the investee, without having control or joint control over those policies. In investments in joint ventures, there is a contractually agreed sharing of control through an arrangement, which exists only when decisions about the relevant activities requiring the unanimous consent of the parties sharing control.

These include all entities initially recognized at cost and adjusted thereafter for the equity method, being increased or reduced from its interest in the investee's income after the acquisition date.

**3.2.2.4 Business combinations**

These are accounted for using the acquisition method when control is transferred to the acquirer. The cost of an acquisition is the sum of the consideration paid, evaluated based on the fair value at the acquisition date, and the amount of any non-controlling interest in the acquiree. For each business combination, the Company recognizes any non-controlling interest in the acquiree either at fair value or at the non-controlling interest's proportionate share of the acquirer's net assets. The costs directly attributable to the acquisition are recorded as expenses when they are incurred, except for costs related to the issuance of debt instruments or equity instruments, which are presented as reductions in debt or equity, respectively.

In a business combination, assets acquired and liabilities assumed are evaluated in order to classify and allocate them, assessing the terms of the agreement, the economic circumstances and other conditions at the acquisition date.

Goodwill is initially measured as the excess of the consideration paid over the fair value of the net assets acquired. After initial recognition, goodwill is measured at cost, net of any accumulated impairment losses. For the purpose of impairment testing, the goodwill recognized in a business combination, as from the acquisition date, is allocated to each of the Company's cash generating units.

Gains on an advantageous purchase are recognized immediately in the result. The borrowing costs are recorded in the income statement as they are incurred.

Contingent liabilities related to tax, civil and labor, classified in the acquired company as possible and remote risks, are recognized by the acquirer at their fair values.

Transactions involving the acquisition of shares with shared control over the net assets traded are evaluated in accordance with the complementary guidance to IFRS 3 - Business Combinations, IFRS 11 and IAS 28 - Investments in Associates and Joint Ventures to evaluate initial recognition criteria.

For the investments defined based on the equity method, investments are initially recognized at cost. The carrying amount of the investment is adjusted for the recognition of changes in the Company's share of the acquirer's Shareholders' equity as at the acquisition date.

Goodwill is measured and segregated from the carrying amount of the investment. Other intangible assets identified in the transaction shall be allocated in proportion to the interest acquired by the Company, based on the difference between the carrying amounts recorded in the acquired entity and its fair value assets, which may be amortized.

**3.2.3 Translation of financial statements into the functional and presentation currency**

The Company has determined that, for the parent company and all its subsidiaries, the functional and presentation currency is the Brazilian Real. The subsidiaries that are exceptions and do not have the Real as their functional currency are:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Suzano Packaging , a foreign subsidiary whose functional currency is the U.S. Dollar;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Simplifyber, an overseas associate whose functional currency is the U.S. Dollar;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Spinnova, an overseas associate whose functional currency is the Euro.

The accumulated gains or losses of which affect the conversion of the financial statements, which are recorded in other comprehensive income, in equity.

The individual financial information of each of the subsidiaries, included in the consolidated financial statement, are prepared in the local currency in which the subsidiary operates and are translated into the Company's functional and presentation currency.

**3.2.4 Transactions and balances in foreign currency**

These are translated using the following criteria:

&nbsp;&nbsp;&nbsp;&nbsp;(i)Monetary assets and liabilities are translated at the exchange rate in effect at year-end;

&nbsp;&nbsp;&nbsp;&nbsp;(ii)Non-monetary assets and liabilities are translated at the historical rate of the transaction;

&nbsp;&nbsp;&nbsp;&nbsp;(iii)Revenue and expenses are translated based on monthly average rate; and

&nbsp;&nbsp;&nbsp;&nbsp;(iv)The cumulative effects of gains or losses upon translation are recognized in the financial results of the year.

The cumulative translation adjustment ("CTA") arising from the translation of a foreign operation previously recognized in other comprehensive income are reclassified from equity to profit or loss at the disposal of the operations. The total or partial disposal of interest in wholly-owned subsidiaries occurs through sale or dissolution, of all or part of operation.

**3.2.5 Segment information**

An operating segment is a component of the Company that carries out business activities from which it can obtain revenue and incur expenses. The operating segments reflect how the Company's management reviews the financial information used to make decisions. The Company's management has identified two reportable segments, which meet the quantitative and qualitative disclosure requirements, in accordance with the current management model (note 28).

The operating segments defined by Management are as follows:

Pulp: comprises the production and sale of short-fiber eucalyptus pulp and fluff pulp, primarily to supply the international market.

Paper: comprises the production and sale of paper to meet the demands of both domestic and international markets. Sales of consumer goods (tissue) are classified within this segment due to their immateriality.

**3.2.6 Financial instruments**

**3.2.6.1 Classification**

Financial instruments are classified based on the purpose for which the financial instruments were acquired, as set forth below:

&nbsp;&nbsp;&nbsp;&nbsp;(i)Amortized cost;

&nbsp;&nbsp;&nbsp;&nbsp;(ii)Fair value through other comprehensive income; and

&nbsp;&nbsp;&nbsp;&nbsp;(iii)Fair value through profit or loss.

Regular purchases and sales of financial assets are recognized on the trade date, meaning the date on which the Company commits to purchase or sell the asset. Financial instruments are derecognized when the rights to receive cash flow from the investments have expired or have been transferred, substantially, all of the risks and rewards of ownership.

**3.2.6.1.1 Financial instruments measured at amortized cost**

Financial instruments held by the Company: (i) in order to receive their contractual cash flow and not to sell to realize a profit or loss; and (ii) whose contractual terms give rise, on specified dates, to cash flow that exclusively represents payments of principal and interest on the principal amount outstanding. They are initially recognized at fair value and subsequently measured at amortized cost using the effective interest rate method, and adjusted for foreign exchange and monetary variations incurred, when applicable. Any changes are recognized under financial income (expenses) in the income statement.

Annually, the Company assesses whether there is evidence that a financial asset is impaired. A financial is impaired only if there is evidence of impairment as a result of one or more events that occurred after the initial recognition of the asset, and that loss event has an impact on the estimated future cash flow of the financial asset that can be estimated reliably.

The criteria the Company uses to determine whether there is evidence of an impairment loss includes:

&nbsp;&nbsp;&nbsp;&nbsp;(i)Significant financial difficulty of the issuer or debtor;

&nbsp;&nbsp;&nbsp;&nbsp;(ii)Defaults on or late payment of interest or principal under the agreement;

&nbsp;&nbsp;&nbsp;&nbsp;(iii)Where the Company, for economic or legal reasons relating to the borrower's financial difficulty, grants to the borrower a concession that a lender would not otherwise consider;

&nbsp;&nbsp;&nbsp;&nbsp;(iv)It becomes probable that the borrower will enter bankruptcy or other financial reorganization;

&nbsp;&nbsp;&nbsp;&nbsp;(v)The disappearance of an active market for that financial asset because of financial difficulties; and

&nbsp;&nbsp;&nbsp;&nbsp;(vi)Observable data indicating a measurable decrease in the estimated future cash flow from a portfolio of financial assets after the initial recognition of those assets, although the decrease cannot yet be identified with the individual financial assets in the portfolio.

The amount of an impairment loss is measured at the difference between the carrying amount of the asset and the present value of estimated future cash flows, discounted at the financial asset's original effective interest rate. If the financial asset is impaired, the carrying amount of the asset is reduced and a loss is recognized in the income statement.

If, in a subsequent remeasurement, if there is an improvement in the asset rating, such as an improvement in the debtor's credit rating, the reversal of the previously recognized impairment loss is recognized in the income statement.

**Cash and cash equivalents**

Include cash on hand, bank deposits and highly liquid short-term investments with maturities, upon acquisition, of 90 days or less, which are readily convertible into known amounts of cash and subject to an insignificant risk of changes in value.

**Trade accounts receivable**

These are recorded at their invoiced amounts, in the normal course of the Company´s business, adjusted for exchange rate variations where denominated in foreign currency and, if applicable, net of expected credit losses.

The Company applies an aging-based provision matrix with appropriate groupings for its portfolio. When necessary, based on individual analyses, the provision for expected losses is supplemented.

The Company examines the maturity of receivables on a monthly basis and identifies those customers with overdue balances, assessing the specific situation of each client, including the risk of loss, the existence of contracted insurance, letters of credit, collateral and the customer's financial situation. In the event of default, collection attempts are made, which include direct contact with customers and collection efforts through third parties. Should these efforts prove unsuccessful, legal measures are considered, and expected credit losses are recognized. The notes are written off from the credit expected loss when Management considers that they are not recoverable after taking all appropriate measures to collect them.

Corresponds to the obligations payable for goods or services acquired in the normal course of the Company´s business.

Supplier finance arrangements are made available for suppliers to anticipate receivables related to the Company's routine purchases. In this transaction, financial institutions pay suppliers who opted for early receipt in exchange for a discount and, when agreed upon between financial institutions and suppliers (the decision to adhere to this transaction is exclusive to the suppliers), the Company pays the financial institutions the total nominal amount of the original obligation on the original payment date. Therefore, these transactions do not change the amounts, nature and timing of the liabilities (including terms, prices and conditions previously agreed upon) and do not affect the Company with the financial charges charged by financial institutions. Additionally, payments made by the Company are directly related to supplier invoices and do not change cash flows. Accordingly, the Company continues to recognize suppliers who opted for drawdown risk in operating activities in the statements of cash flows.

**Loans, financing and debentures**

General or specific borrowing costs, directly attributable to the acquisition, construction or production of a qualifying asset, are capitalized as a part of the cost of that asset when it is probable that they will provide future economic benefits for the entity, and that such cost can be measured with reliability. The Company does not have specific loans to obtain qualifying assets. Other loan costs are recognized as expenses in the period during which they are incurred.

**3.2.6.1.2 Financial instruments at fair value through other comprehensive income**

Financial instruments at fair value through other comprehensive income are financial assets held by the Company: (i) either to receive their contractual cash flow through sale with the realization of a profit or loss; and (ii) whose contractual terms give rise, on specified dates, to cash flows constituting, exclusively, repayments of principal and interest on the principal amount outstanding. In addition, this category includes investments in equity instruments where, upon initial recognition, the Company elected to present subsequent changes in its fair value within other comprehensive income. Any changes are recognized under net financial income (expenses) in the income statement, except for the fair value of investments in equity instruments, which are recognized in other comprehensive income.

Includes the balance presented in Note 14.1 as other investments evaluated at fair value through other comprehensive income.

For such financial assets, the Company periodically assesses whether there are significant or prolonged reductions in the fair value of the instrument below its cost, in order to identify potential impairment and the corresponding impairment loss, measured as the difference between the acquisition cost and the current fair value, less any loss previously recognized in other comprehensive income.

**3.2.6.1.3 Financial instruments at fair value through profit or loss**

Financial instruments at fair value through profit or loss are either designated in this category or not classified in any of the other categories. Any changes are recognized within financial income (expenses) in the income statement for non-derivative financial instruments and for financial derivative instruments within income from derivative financial instruments.

 **Derivative financial instruments and hedging activities**

Hedging instruments are derivatives executed exclusively for the purpose of mitigating the Company's financial risks.

Embedded derivatives in non-derivative main contracts are required to be separated when their risks and characteristics are not closely related to those of the respective main contracts, and these are not measured at fair value through profit or loss.

Non-option embedded derivatives are separated from the respective main contracts in accordance with the stated or implied substantive terms, so they have a zero fair value upon initial recognition.

**3.2.7 Inventories**

These are evaluated at the average acquisition or formation cost of the finished products, net of recoverable taxes, not exceeding their net realizable value.

Finished products and work-in-process consist of raw materials, direct labor, production costs, freight, storage and general production expenses, which are related to the processes required to make the products available for sale.

Imports in transit are presented at the cost incurred up to the balance sheet date.

Raw materials derived from biological assets are measured based on their fair value, less costs to sell at the point of harvest and freight costs.

Provisions for obsolescence, adjustments to net realizable value, impaired items and slow-moving inventories are recorded when necessary. Usual production losses are recorded and are an integral part of the production costs for the respective month, whereas unusual losses, if any, are recorded directly as part of cost of sales.

**3.2.8 Biological assets**

The biological assets for production (mature and immature forests) are reforested eucalyptus forests, with a formation cycle between planting and harvest from 6 to 7 years, measured at fair value. Depletion is measured based on the amount of biological assets depleted (harvested) and measured at fair value at the time of harvest.

For the determination of the fair value, the income approach technique was applied, using the discounted cash flow model, according to the projected productivity cycle for these assets. The assumptions used to measure the fair value are reviewed every six months, as the Company considers that this interval is sufficient to ensure no significant gaps in the fair value balance of biological assets booked. Significant assumptions are presented in Note 13.

The gain or loss on the assessment of fair value is recognized in operating income (expenses), net.

Biological assets in the process of formation under the age of 2 (two) years are recorded for at their formation cost. Areas of permanent environmental preservation are not recorded, because these are not characterized as biological assets, and are not included in the measurement at fair value.

**3.2.9 Property, plant and equipment**

Stated at their cost of acquisition, formation, construction or dismantling, net of recoverable taxes. This cost is deducted from the accumulated depreciation and accumulated impairment losses, when incurred, at the higher of the value in use or the proceeds from sale less cost to sell. The borrowing costs are capitalized as a component of construction in progress, at the weighted average rate of the Company's debt at the capitalization date, adjusted for the equalization of exchange rate effects.

Depreciation is recognized based on the estimated economic useful life of each asset on a straight-line basis. The estimated useful lives, residual values and depreciation methods are reviewed annually, and the effects of any changes in estimates are accounted for prospectively. Land is not depreciated.

The Company performs an annual analysis of impairment indicators of property, plant and equipment. Impairment for losses on property, plant and equipment are only recognized if the related cash-generating unit is devalued, or if the asset's recoverable amount is less than its carrying amount. The recoverable amount of the asset or cash-generating unit is the higher of its value in use, and its fair value less costs to sell.

The cost of major renovations is capitalized if the future economic benefits exceed the performance standards initially estimated for the asset and are then depreciated over the remaining useful life of the related asset.

Repairs and maintenance are expensed as incurred.

Gains and losses on disposals of property, plant and equipment are measured by comparing the proceeds with the book value and are recognized as other operating income (expenses), net, at the disposal date.

**3.2.10 Leases**

A contract is, or contains, a lease if the right to control the use of an identified asset for a period of time is transferred in exchange for consideration, for which it is necessary to assess whether:

&nbsp;&nbsp;&nbsp;&nbsp;i.The contract involves the use of an identifiable asset, which may be explicit or implicit, and may be physically distinct or represent almost the entire capacity of a physically distinct asset. If the supplier has a substantial right to replace the asset, then the asset is not identified;

&nbsp;&nbsp;&nbsp;&nbsp;ii.The Company has the right to obtain substantially all the economic benefits from the use of the asset during the contract period; and

&nbsp;&nbsp;&nbsp;&nbsp;iii.The Company has the right to direct the use of the asset, meaning the Company has the right to decide to change how and for what purpose the asset is used, if:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• It has the right to operate the asset, or

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• It designed the asset, in a way that predetermines how and for what purpose it will be used.

At the beginning of the contract, the Company recognizes a right-of-use asset and a lease liability that represents the obligation to make payments related to the asset underlying the lease.

The right-to-use asset is initially measured at cost, which includes the initial amount of the lease liability adjusted for any payments made up to the contract start date, plus any direct initial costs incurred, and estimated costs of disassembly, removal, or restoration of the asset in the place where it is located, less any incentives received.

The right-to-use asset is subsequently depreciated using the straight-line method from the start date to the end of the useful life of the right to use, or the end of the lease term, whichever is shorter. Except for land agreements that are automatically extended for the same period through a notification to the lessor, other agreements are not allowed automatic renewals for an indefinite period, since both parties have the right to terminate the agreements.

The lease liability is initially measured at the present value of the payments not made, less the incremental loan rate.

The lease liability is measured at amortized cost using the effective interest method. It is remeasured when there is a change:

&nbsp;&nbsp;&nbsp;&nbsp;i.In future payments resulting from a change in index or rate;

&nbsp;&nbsp;&nbsp;&nbsp;ii.In the estimate of the expected amount to be paid, at the guaranteed residual value; or

&nbsp;&nbsp;&nbsp;&nbsp;iii.In the assessment of whether the Company will exercise the purchase option, extension or termination.

When the lease liability is remeasured, the corresponding adjustment amount is recorded in the book value of the right-of-use asset, or in the statement of profit and loss, if the book value of the right-of-use asset has been reduced to zero.

The Company does not have lease agreements with clauses imposing:

&nbsp;&nbsp;&nbsp;&nbsp;i.Variable payments that are based on the performance of the leased assets;

&nbsp;&nbsp;&nbsp;&nbsp;ii.Guarantees of residual value; and

&nbsp;&nbsp;&nbsp;&nbsp;iii.Restrictions, such as, for example, an obligation to maintain financial ratios.

Short-term or low-value contracts which are exempt from these standards are contracts where the individual value of the assets is lower than US$5, and for which the maturity date is shorter than 12 months, are expensed as incurred.

**3.2.11 Intangible assets**

These are measured at cost at the time when they are initially recognized. The cost of intangible assets acquired during a business combination corresponds to the fair value at the acquisition date. After initial recognition, intangible assets are presented at cost less accumulated amortization and impairment losses, when applicable.

The useful life of intangible assets are assessed as finite or indefinite.

Intangible assets with a finite life are amortized over the economically useful lives and reviewed for impairment whenever there is an indication that their carrying values may be impaired. The amortization period and method for intangible assets with finite useful lives are reviewed at least at the end of each fiscal year. The amortization of intangible assets with finite useful lives is recognized in the statement of income as an expense related to its use, and in line with the economically useful life of the intangible asset.

Amortization of supplier and port services contracts, port concessions, lease agreements, and cultivars is recognized in cost of sales. Amortization of customer relationships is recognized in selling and marketing expenses. Amortization of trademarks and patents, non-compete agreements, research and development agreements, and system development and implementation costs is recognized in general and administrative expenses. Amortization of software is recognized based on its functional use and may be included in cost of sales, selling or general and administrative expenses.

Intangible assets with indefinite useful lives are not amortized, but are tested annually for impairment losses, individually or at the CGU level. The allocation is made to the CGU or group of CGUs that represents the lowest level within the entity for which goodwill is monitored for management's internal purposes, that has benefited from the business combination. The Company mainly records in this subgroup goodwill for expected future profitability (goodwill) and easement of passage.

This testing involved the adoption of significant assumptions and judgments, disclosed in Note 16.

**3.2.12 Current and deferred income tax and social contribution and uncertainty over income tax treatments (IFRIC 23)**

Income taxes include income tax and social contribution on net income, current and deferred. These taxes are recognized in the income statement, except to the extent that they relate to items recognized directly in equity. In this case, they are recognized in equity under other reserves.

Subsidiaries domiciled in Brazil have their taxes calculated and provisioned in accordance with the current legislation and their specific tax regime, including, in some cases, the presumed profit method. Subsidiaries domiciled abroad are subject to taxation in their respective jurisdictions, according to local regulations.

The current charge is calculated based on the tax laws enacted in the countries in which the Company and its subsidiaries and affiliates operate and generate taxable income. Management periodically evaluates the positions assumed in the income tax returns with respect to situations in which the applicable tax regulations give rise to interpretations and establishes provisions, when appropriate, based on the amounts that must be paid to the tax authorities.

Deferred tax and contribution liabilities are recognized on temporary differences between the tax bases of assets and liabilities and their carrying amounts in the financial statements. Deferred taxes and contributions are determined based on the rates in force on the balance sheet date, and which must be applied when they are realized or settled.

Deferred tax assets and contributions are recognized to the extent that it is probable that future taxable profits will be available for use to offset temporary differences, based on the projections of future results prepared and based on internal assumptions and future economic scenarios that may, therefore, undergo changes.

The projection for the realization of deferred tax assets was prepared based on Management's estimates that are based on significant judgments and assumptions relating to net average pulp and paper prices, and the transfer prices with the subsidiaries based in Austria. However, there are other assumptions that are not under the control of the Company, such as inflation rates, exchange rates, pulp prices in the international market, and other economic uncertainties in Brazil, which mean that future results may differ from those considered in the preparation of the consolidated projection.

Deferred income tax and social contribution are recognized on temporary differences arising from investments in subsidiaries and associates, except when the timing of the reversal of temporary differences is controlled by the Company, and if it is probable that the temporary differences will not be reversed in the foreseeable future.

Deferred tax and contribution assets and liabilities are offset and presented at their net amounts in the balance sheet whenever they are related to the same legal entity and the same tax authority.

The parcel of the adjustment of the value of the investment in subsidiaries, direct and indirect, domiciled abroad, equivalent to the profit earned by them before income tax, except for exchange rate variation, is added in the determination of taxable income and the social contribution calculation basis of the controlling entity domiciled in Brazil, at each year ended.

**3.2.13 Provisions, contingent assets and liabilities**

Contingent assets are not recorded. Recognition is only performed when there are guarantees or favorable judicial decisions and the amounts of these can be measured reliably. Contingent assets for which such conditions are not met are only disclosed in the notes to the financial statements when their amounts are material.

Provisions for liabilities are made to the extent that the Company expects that is probable that it will disburse cash, and the amount can be reliably estimated. Tax, civil, environmental and labor proceedings are accrued when losses are assessed as probable, and the amounts involved can be measured reliably, being recorded net of judicial deposits, under "provisions for judicial liabilities". When the expectation of loss is possible, a description of the processes and amounts involved is disclosed in the notes to the financial statements. Contingent liabilities assessed as representing remote losses are neither accrued nor disclosed.

Contingent liabilities arising from business combinations are recognized if they arise from a present obligation as a result of from past events, and if their fair values can be measured reliably, and are subsequently measured at the higher of:

&nbsp;&nbsp;&nbsp;&nbsp;i.The amount that would be recognized in accordance with the accounting policy for the provisions above that comply with IAS 37; or

&nbsp;&nbsp;&nbsp;&nbsp;ii.The amount initially recognized less, where appropriate, revenue recognized in accordance with the accounting treatment of revenue from customer contracts under IFRS 15.

Principal and penalties amounts related to Tax, civil, environmental and labor proceedings are under other operating income and expenses and the interest is recognized in the net financial result.

The realization of provisions for judicial liabilities and contingent liabilities arising from business combinations, with possible and remote probability of loss, are recognized under other operating income and expenses or cash depending on the court decision.

**3.2.14 Share based payments**

The Company's executives and managers receive part of their compensation through share-based payment plans, settled in cash and shares.

Expenses related to these plans are recognized in the income statement as administrative expenses over the vesting period, based on the fair value determined at the grant date for equity-settled plans and remeasured at each reporting date for cash-settled plans. The changes in the fair value of cash-settled plans are recognized under administrative expenses in the statement of profit or loss. The corresponding entry is recognized in non-current liabilities for cash-settled plans and in shareholders' equity for equity-settled plans.

**3.2.15 Employee benefits**

The Company offers benefits through a supplementary contribution plan to all employees, as well as medical assistance and life insurance for a determined group of former employees, and for the latter two benefits an annual actuarial appraisal is prepared by an independent actuary, and are reviewed by Management. The respective impact is recognized in employee benefit plans.

Actuarial gains and losses are recognized in other reserves when incurred. The interest incurred, resulting from changes in the present value of the actuarial liability, is recorded in the income statement within financial expenses.

**3.2.16 Government grants and assistance**

Government grants and assistance are recognized at fair value when it is reasonably certain that the conditions established by the granting Governmental Authority were observed, and that these subsidies will be obtained. These are recorded as deductions expenses in the income statement for the period of enjoyment of the benefit, and subsequently allocated to the tax incentives reserve under shareholders' equity, when applicable.

**3.2.17 Revenue recognition**

Revenue from contracts with customers is recognized at the time when control of the products is transferred to customers, represented by the ability to determine the use of products and obtain substantially all the remaining benefits from the products.

For the Pulp operating segment, revenue recognition occurs when control is transferred to the buyer who assumes the remaining benefits of the asset and is based on the parameters provided by: (i) International Commercial Terms ("Incoterms"), when destined for the foreign market; and (ii) lead times, when destined for the internal market.

For the Paper and Consumer Goods operating segments, revenue is also recognized upon the transfer of control to the customer, based on (i) the applicable Incoterms and (ii) the lead time, for transactions carried out in both foreign and domestic markets.

Revenue is measured at the fair value of the consideration received or receivable, net of taxes, returns, rebates and discounts, and recognized in accordance with the accrual basis of accounting, when the amount can be reliably measured.

Accumulated experience is used to estimate and provide for rebates and discounts, using the expected value method, and revenue is only recognized to the extent that it is highly unlikely that a significant reversal will occur. A provision for reimbursement (included in trade accounts receivable) is recognized for expected rebates and discounts payable to customers in relation to sales made until the end of the reporting period. No significant element of financing is deemed to be present, as sales are made with short credit terms.

**3.2.18 Employee and management profit sharing**

Employees are entitled to profit sharing based on certain goals agreed annually. For the Administrators, the basis is the legal and statutory provisions proposed by the Board of Directors and approved by the shareholders are used as a basis. Provisions for participation are recognized in the payroll and charges against to administrative expenses during the period in which the targets are attained.

**3.2.19 Material accounting judgments, estimates and assumptions**

As disclosed in Note 2, Management applied judgments, estimates, and accounting assumptions to reflect future conditions and expectations. Such assumptions, based on available information and relevant economic factors, may involve uncertainties that could result in significant changes in the carrying amounts of assets, liabilities, income, and expenses in subsequent periods.

The Company reviews the estimates and underlying assumptions used in its accounting estimates on an annual basis. Revisions to the accounting estimates are recognized in the period during which the estimates are revised. The main matters subject to these estimates are presented below:

**Fair value of financial instruments (Note 4):**

The measurement of the fair value of financial instruments requires significant management judgment, especially for transactions contracted in over-the-counter markets or with low liquidity. These calculations involve assumptions regarding future interest rates, foreign exchange coupon curves, volatility, commodity prices, and counterparties' credit risk, using models such as discounted cash flow and Garman-Kohlhagen for options. The estimates consider normal market conditions at the reporting date, without forced liquidation, and rely on observable inputs (rates, curves, volatilities) and unobservable inputs (spreads and risk adjustments), in accordance with IFRS 13 fair value hierarchy. Changes in these assumptions, such as variations in interest rate curves, exchange rates, or input prices, may significantly impact the fair values recognized, affecting assets, liabilities, and the results for the period.

The main risks arise from the volatility of financial markets and the sensitivity of the assumptions used in fair value measurement. Abrupt changes in exchange rates, interest rates, or commodity prices may result in significant adjustments to derivative and non-derivative financial instruments, influencing profit or loss and equity. In addition, external factors such as economic crises, regulatory changes, or reduced liquidity may affect the reliability of the estimates, increasing the subjectivity of the calculations. As these instruments are predominantly classified within Level 2 of the fair value hierarchy, there is greater reliance on internal models and unobservable inputs, which increases the degree of uncertainty. Suzano mitigates these risks through robust financial policies, daily monitoring of positions, sensitivity analyses, and periodic reviews of the assumptions used.

**Annual analyses of the recoverability of taxes (Notes 9 and 12):**

The annual assessment of the recoverability of taxes is essential to ensure that deferred tax assets and tax credits recognized by Suzano appropriately reflect the expectation of future realization. These assets depend on projections of taxable results, offsetting plans, and interpretations of tax legislation, requiring significant management judgment. The determination of recoverability involves assumptions regarding economic growth, future profitability, the utilization of tax losses and negative bases of corporate income tax and social contribution, as well as the assessment of risks related to uncertain tax positions in accordance with ICPC 22/IFRIC 23.

As these estimates are sensitive to changes in the economic and regulatory environment, their proper measurement is critical to the transparency and reliability of the financial statements.

The main risks arise from uncertainty regarding the generation of sufficient taxable profits to realize tax credits, as well as the possibility of changes in legislation or tax interpretations that may affect the utilization of these assets. Changes in profit projections, revisions to strategic plans, or unfavorable decisions in tax disputes may lead to the need for significant adjustments to the recorded balances. In addition, because this assessment involves judgments about future scenarios and complex tax positions, there is a risk of volatility in profit or loss and equity if the assumptions do not materialize. Suzano mitigates these risks through periodic reviews, support from legal opinions, and continuous monitoring of tax contingencies.

**Fair value of biological assets (Note 13):**

The measurement of the fair value of biological assets is essential to appropriately reflect, in Suzano's financial statements, the economic value of the eucalyptus forests used as raw material in pulp production. This process involves significant assumptions, such as mean annual increment (IMA), wood prices, establishment costs, land opportunity cost, discount rate (WACC), and inflation, all based on long-term projections and region-specific conditions. As these variables are sensitive to changes in market conditions, climate, and productivity, the judgments and estimates applied by Management have a direct impact on the carrying amount of the assets and, consequently, on the Company's results.

---

The main risks arise from the inherent uncertainty in the assumptions used to calculate fair value. Variations in wood prices, forest growth rates (IMA), establishment costs, or the discount rate may result in significant adjustments to biological assets and affect operating results. In addition, external factors such as regulatory changes, climatic events, pests, or fires may impact productivity and projected cash flows, increasing fair value volatility. As this measurement is classified as Level 3 in the IFRS 13 fair value hierarchy and is based on unobservable inputs, there is a higher degree of subjectivity and a need for robust controls to ensure the reliability of the information.

**Annual analysis recoverable amount of goodwill (Note 16):**

Goodwill is tested for recoverability annually or whenever there are indications of impairment. For testing purposes, assets are allocated to the Cash-Generating Units (CGUs) to which the goodwill is associated. The recoverable amount is determined based on value in use, calculated from discounted cash flows, considering financial projections approved by Management for a five-year horizon, plus a long-term growth rate for subsequent periods.

Key assumptions include the discount rate (WACC), which reflects the weighted average cost of capital adjusted for business risk and market conditions; the perpetuity growth rate, based on sustainable growth expectations for the sector; operating margins, estimated according to historical performance and market outlook; and revenue projections, based on macroeconomic assumptions, competitive dynamics, and strategic plans.

These assumptions involve significant judgment and are subject to uncertainties, particularly regarding the discount rate, where variations can substantially impact the recoverable amount; the growth rate, where changes can reduce the test's safety margin; and operational performance, which may be affected by changes in the economic or competitive environment, impacting revenue and margin projections. If these assumptions do not materialize, an impairment loss may need to be recognized in future periods.

**Provision for judicial liabilities (Note 20):**

The Company is a party to judicial and administrative proceedings of a tax, civil, environmental and labor nature. A provision for legal contingencies is recognized when there is a present obligation arising from past events and when Management, based on the opinion of legal counsel, considers an outflow of resources to settle the obligation to be probable and the amount involved can be reliably estimated.

The amount provided is calculated taking into account the probability of loss, classified as probable, possible or remote according to legal assessment; the estimated cash outflow, based on the history of decisions, applicable case law and the procedural stage of the cases; and monetary restatement and charges, applied in accordance with applicable legislation.

Significant assumptions include legal interpretation, as changes in case law or decisions by higher courts may significantly affect the probability of loss; the estimation of amounts, which may vary as a result of new calculations, expert reports or updates to legal bases; and the regulatory environment, since legislative changes may impact the obligation or the estimated amount.

The provisions involve significant judgments and are subject to uncertainties, especially in long-term proceedings or cases involving complex matters. Should there be changes in assumptions or in legal interpretation, additional provisions may be recognized or reversals may occur in future periods.

**3.3 Accounting policies not yet adopted**

The new and changed standards and interpretations issued, but not yet adopted up to December 31, 2025, are described below. The Company intends to adopt these new standards, changes and interpretations, if applicable, when they come into force, and does not expect them to have a material impact on the financial statements except for the IFRS 18 as disclosed below.

**3.3.1 Amendment to IFRS 9 and IFRS 7 - Classification and Measurement of Financial Instruments (applicable for annual on/or after January 1, 2026)**

On 30 May 2024, the IASB issued targeted amendments to IFRS 9 and IFRS 7 to respond to recent questions arising in practice, and to include new requirements not only for financial institutions but also for corporate entities. These amendments:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• clarify the date of recognition and derecognition of some financial assets and liabilities,with a new exception for some financial liabilities settled through an electronic cash transfer system;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• clarify and add further guidance for assessing whether a financial asset meets the solely payments of principal and interest (SPPI) criterion;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• add new disclosures for certain instruments with contractual terms that can change cash flows (such as some financial instruments with features linked to the achievement of environment, social and governance targets); and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• update the disclosures for equity instruments designated at fair value through other comprehensive income (FVOCI).

**3.3.2 IFRS 18 Presentation and Disclosure in Financial Statements (applicable for annual on/or after January 1, 2027)**

In April 2024, the IASB issued IFRS 18 – Presentation and Disclosure in Financial Statements, which will replace IAS 1 – Presentation of Financial Statements, introducing new requirements with the aim of increasing the comparability of financial performance between entities and providing more relevant and transparent information to users of financial statements.

Although IFRS 18 does not change the recognition or measurement of items, significant impacts are expected on the presentation and disclosure of financial statements, especially with regard to the structure of the income statement, the disclosure of performance measures defined by management, the principles of aggregation and disaggregation of information, and certain aspects of the cash flow statement.

The Company is currently assessing the impacts of adopting IFRS 18 on its consolidated financial statements. Based on a preliminary assessment, the following possible effects stand out, among others: changes in the presentation of results, resulting from the new classification of revenues and expenses into standardized categories and the introduction of new subtotals; possible adjustments in the presentation of the main financial statements, with the regrouping or greater detail of certain lines, in accordance with the new principles of aggregation and disaggregation; new disclosure requirements related to performance measures defined by Management; and adjustments in the presentation of the cash flow statement, in accordance with the new requirements of the standard.

IFRS 18 is effective for fiscal years beginning on or after January 1, 2027, with retrospective application, so that comparative information for the fiscal year ended December 31, 2026, will be restated upon initial adoption of the standard.

**3.3.3 IFRS 19 Subsidiaries without Public Accountability: Disclosures (applicable for annual on/or after January 1, 2027)**

Issued in May 2024, IFRS 19 allows for certain eligible subsidiaries of parent entities that report under IFRS Accounting Standards to apply reduced disclosure requirements.

**3.3.4 Amendment to IAS 21 - Effects of Changes in Foreign Exchange Rates (applicable for annual on/or after January 1, 2027)**

On 13 November 2025, the IASB issued targeted amendments to IAS 21 specifying the procedures to be applied for translating amounts from a functional currency of a non-hyperinflationary economy into a presentation currency of a hyperinflationary economy.

**3.3.5 Annual Improvements to IFRS Accounting Standards – Volume 11**

These amendments are intended to enhance clarity in the wording of certain standards (IFRS 1, IFRS 7, IFRS 9, IFRS 10 and IAS 7) and to remedy omissions, inconsistencies or unintended effects resulting from the application of such standards.

**4 FINANCIAL INSTRUMENTS AND RISKS MANAGEMENT**

**4.1 Financial risks management**

**4.1.1 Overview**

As a result of its activities, the Company is exposed to various financial risks, which are managed in accordance with the Financial Risk Management, Counterparty and Issuer Risk, Debt, Derivative and Cash Management Policies ("Financial Policies") approved at the Board of Directors' meeting.

The main factors considered by Management are:

&nbsp;&nbsp;&nbsp;&nbsp;(i)Liquidity;

&nbsp;&nbsp;&nbsp;&nbsp;(ii)Credit;

&nbsp;&nbsp;&nbsp;&nbsp;(iii)Exchange rate;

&nbsp;&nbsp;&nbsp;&nbsp;(iv)Interest rate;

&nbsp;&nbsp;&nbsp;&nbsp;(v)Fluctuations of pulp selling and commodity prices; and

&nbsp;&nbsp;&nbsp;&nbsp;(vi)Capital.

Management are focused on generating consistent and sustainable results over time, however, arising from external risk factors, unintended levels of volatility can influence the Company's cash flow and income statement.

The Company has policies and procedures for managing market risk which aims to:

&nbsp;&nbsp;&nbsp;&nbsp;(i)Reduce, mitigate or transfer exposure with the aim of protecting the Company's cash flow and assets against fluctuations in the market prices of raw material and products, exchange rates and interest rates, price and adjustment indices ("market risk") or other assets or instruments traded in liquid or illiquid markets to which the value of the assets, liabilities and cash flow are exposed;

&nbsp;&nbsp;&nbsp;&nbsp;(ii)Establish limits and instruments with the purpose of allocating the Company's cash to financial institutions falling within acceptable credit risk exposure parameters; and

&nbsp;&nbsp;&nbsp;&nbsp;(iii)Optimize the process of contracting financial instruments for protection against exposure to risk, drawing on natural hedges and correlations between the prices of different assets and markets, avoiding any waste of funds for inefficient transactions. All financial transactions entered into by the Company aim to protect existing exposures, with the assumption of new risks being prohibited, except those arising from its operating activities.

Hedging instruments are contracted exclusively for hedging purposes and are based on the following terms:

&nbsp;&nbsp;&nbsp;&nbsp;(i)Protection of cash flow against currency mismatches;

&nbsp;&nbsp;&nbsp;&nbsp;(ii)Protection of revenue flows for debt settlement and interest payments against fluctuations in interest rates and currencies; and

&nbsp;&nbsp;&nbsp;&nbsp;(iii)Protection against fluctuations in the prices of pulp and other supplies related to production.

The Treasury team is responsible for identification, evaluating and seeking protection against possible financial risks. The Board of Directors approves financial policies that establish the principles and guidance for global risk management, the areas involved in these activities, the use of derivative and non-derivative financial instruments, and the allocation of a cash surplus.

The Company only uses the most liquid financial instruments, and:

&nbsp;&nbsp;&nbsp;&nbsp;(i)Does not enter into leveraged transactions or other forms of embedded options that change the purpose of protection (hedge);

&nbsp;&nbsp;&nbsp;&nbsp;(ii)Does not have double-indexed debt or other forms of implied options; and

&nbsp;&nbsp;&nbsp;&nbsp;(iii)Does not have any transactions requiring margin deposits or other forms of collateral for counterparty credit risk.

The Company does not use hedge accounting. Therefore, gains and losses from derivative operations are fully recognized in the statements of income, as disclosed in Note 26.

**4.1.3 Fair value of loans and financing**

The financial instruments are recognized at their contractual amounts. In order to determine the market values of financial instruments traded in public and liquid markets, the market closing prices were used at the balance sheet dates. The fair values of interest rate and index swaps are calculated based on the present value of their future cash flow, discounted at the current interest rates available for transactions with similar remaining terms to maturity. This calculation is based on the quotations of B3 and ANBIMA for interest rate transactions in Brazilian Reais, and the Federal Reserve Bank of New York and Bloomberg for Secured Overnight Financing Rate ("SOFR") transactions. The fair value of forward or forward exchange agreements is determined using the forward exchange rates prevailing at the balance sheet dates, in accordance with B3 prices.

In order to determine the fair values of financial instruments traded in over-the-counter or unliquidated markets, a number of assumptions and methods based on normal market conditions and not for liquidation or forced sale, are used at each balance sheet date, including the use of option pricing models such as Garman-Kohlhagen, and estimates of discounted future cash flow. The fair value of agreements for the fixing of oil bunker prices is obtained based on the Platts index.

The estimated fair values of loans and financing are set forth below:

Management considers that, for its other financial assets and liabilities measured at amortized cost, their book values approximate their fair values, and therefore the fair value information is not being presented.

**4.2 Liquidity risk management**

The Company's purpose is to maintain a strong cash and marketable securities position to meet its financial and operating commitments. The amount held in cash is intended to cover the expected outflows in the normal course of its operations, while the cash surplus is generally invested in highly liquid financial investments according to the Cash Management Policy.

The cash position is monitored by the Company's Management, by means of management reports and participation in performance meetings with determined frequencies.

In the year ended December 31, 2025, the variations in cash and marketable securities were as expected, and the cash generated from operations was mostly used for investments and debt service.

All derivative financial instruments were traded over the counter and do not require deposit guarantee margins.

The remaining contractual maturities of financial liabilities are presented as of the balance sheet date.

The amounts as set forth below consist of undiscounted cash flow, and include interest payments and exchange rate variations, and therefore may not reconcile with the amounts disclosed in the balance sheet.

**4.3 Credit risk management**

Related to the possibility of non-compliance with the counterparties' commitments as part of a transaction. Credit risk is managed on a group basis and arises from cash equivalents, marketable securities, derivative financial instruments, bank deposits, Bank Deposit Certificates ("CDB"), fixed income box, repurchase agreements, letters of credit, insurance, receivable terms of customers, and advances to suppliers for new projects, among others.

**4.3.1 Trade accounts receivable**

The Company has commercial and credit policies aimed at mitigating any risks arising from defaults by its customers, mainly through contracting credit insurance policies, bank guarantees provided by first-tier banks, and collateral based on liquidity. Moreover, portfolio customers are subject to internal credit analysis aimed at assessing the risks regarding payment performance, both for exports and for domestic sales.

For customer credit assessment, the Company applies a matrix based on the analysis of qualitative and quantitative aspects to determine the individual credit limits to each customer according to the identified risks. Each analysis is submitted for approval according to an established hierarchy and, if applicable, for approval at a Management meeting and by the Credit Committee.

The risk classification of trade accounts receivable is set forth below:

---

| | | |
|:---|:---|:---|
| | **Consolidated** | **Consolidated** |
| | **12/31/2025** | **12/31/2024** |
| &nbsp;&nbsp;&nbsp;&nbsp;Low - current and overdue up to 30 days | **6270686** | 8899516 |
| &nbsp;&nbsp;&nbsp;&nbsp;Average - overdue between 30 and 90 days | **154155** | 174048 |
| &nbsp;&nbsp;&nbsp;&nbsp;High - overdue more than 90 days | **267314** | 89596 |
|  | **6692155** | **9163160** |

---

A portion of the amounts above does not consider the expected credit losses calculated based on the provision matrix of R$131,548 and R$30,300 as of December 31, 2025 and 2024, respectively.

**4.3.2 Banks and financial institutions**

The Company, in order to mitigate its credit risk, ensures its financial operations are diversified among banks, with a main focus on first-tier financial institutions classified as high-grade with the majority of its balance having a brAAA risk rating — that is, those with a high level of credit quality and low risk according to the main credit rating agencies.

The book value of financial assets representing exposure to credit risk is set forth below:

---

| | | |
|:---|:---|:---|
| | **Consolidated** | **Consolidated** |
| | **12/31/2025** | **12/31/2024** |

1) We use the Brazilian Risk Ratings issued by the agencies Fitch Ratings, Standard & Poor's and Moody's.

**4.4 Market risk management**

The Company is exposed to several market risks, mainly related to fluctuations in exchange rate variations, interest rates, inflation rates, pulp selling prices and commodity prices that could affect its results and financial situation.

To mitigate the impacts, the Company has processes to monitor its exposure and policies that could support the implementation of risk management.

These policies establish the limits and the instruments to be implemented for the purpose of:

&nbsp;&nbsp;&nbsp;&nbsp;(i)Protecting cash flow due to currency mismatch;

&nbsp;&nbsp;&nbsp;&nbsp;(ii)Mitigating exposure to interest rates;

&nbsp;&nbsp;&nbsp;&nbsp;(iii)Reducing the impacts of fluctuations in commodity's prices; and

&nbsp;&nbsp;&nbsp;&nbsp;(iv) Changes to debt indexes.

Market risk management involves the identification, assessment and implementation of the strategy, with the effective contracting of adequate financial instruments.

**4.4.1 Exchange rate risk management**

The fundraising, financing and currency hedging policies of the Company are guided by the fact that a substantial part of the net revenue arises from exports with prices negotiated in US Dollars, while a substantial part of the production costs are in Brazilian Reais. This structure allows the Company to enter into export financing arrangements in US Dollars, and to reconcile the financing payments with the cash flow of receivables from sales in foreign markets, using the international bond market as an important portion of its capital structure, and providing a natural cash hedge for these commitments.

Moreover, the Company enters into US$ selling transactions in the futures markets, including strategies involving options, to ensure attractive levels of operating margins for a portion of revenue. Such transactions are limited to a percentage of the net surplus foreign currency over a 24-months' time horizon and therefore, are matched to the availability of currency for sale in the short term.

The assets and liabilities that are exposed to foreign currency, substantially in US$, are set forth below:

---

| | | |
|:---|:---|:---|
| | **12/31/2025** | **12/31/2024** |
| **Assets** | | |
| &nbsp;&nbsp;&nbsp;&nbsp;Cash and cash equivalents | **11919897** | 6496039 |

**4.4.1.1 Sensitivity analysis – foreign exchange rate exposure – except for derivative financial instruments**

For market risk analysis, the Company uses scenarios to evaluate both its asset and liability positions in foreign currency, and the possible effects on its results. The probable scenario represents the amounts recognized, as they reflect the conversion into Brazilian Reais on the balance sheet date (R$ to US$ = R$5.5024).

This analysis assumes that all other variables, particularly interest rates, remain constant. The other analyses considered unfavorable scenarios of the Brazilian Real against the US$ at the rates of 25% and 50% before taxes.

**4.4.1.2 Sensitivity analysis – foreign exchange rate exposure – derivative financial instruments** 

The Company has sales operations in US$ in the futures markets, including strategies using options, to ensure attractive levels of operating margins for a portion of its revenue. These operations are limited to a percentage of the total exposure to US$ over a 24-month horizon, and are therefore pegged to the availability of ready-to-sell foreign exchange in the short term.

In addition to the transaction described above, the Company also taken out derivative instruments linked to the US$ and subject to exchange fluctuations, seeking to adjust the debt's currency indexation to the cash generation currency, as provided for in its financial policies.

For the calculation of the mark-to-market ("MtM") price, the exchange rate of the last business day of the period is used. These market movements caused a negative impact on the mark-to-market position entered into by the Company.

This analysis below assumes that all other variables, particularly the interest rates, remain constant. The other analyses considered unfavorable scenarios of the Brazilian Real against the US$ by 25% and 50%, before taxes, based on the base scenario on December 31, 2025.

The following table set out the possible impacts assuming these scenarios:

---

| | | | |
|:---|:---|:---|:---|

**4.4.2 Interest rate risk management**

Fluctuations in interest rates could increase or reduce the costs of new loans and existing contracted operations.

The Company is constantly looking for alternatives for the use of financial instruments in order to avoid negative impacts on its cash flow due to fluctuations in interest rates in Brazil or abroad.

**4.4.2.1 Sensitivity analysis – exposure to interest rates – except for derivative financial instruments**

For its market risk analysis, the Company uses scenarios to evaluate the sensitivity of changes in operations impacted by the following rates: Interbank Deposit Rate ("CDI"), Long Term Interest Rate ("TJLP"), Long Term Rate ("TLP"), Special System for Settlement and Custody ("SELIC") and SOFR, which could impact the results.

The probable scenario represents the amounts already booked, as they reflect Management's best estimates.

This analysis assumes that all other variables, particularly exchange rates, will remain constant. The other scenarios considered a depreciation of 25% and 50% in market interest rates.

The following table set forth the possible impacts assuming these scenarios in absolute amounts:

**4.4.3 Pulp and commodity price risk management**

The Company is exposed to the selling price of pulp and commodity prices in the international market. The dynamics of rising and falling production capacities in the global market, demand and macroeconomic conditions may impact the Company´s operating results.

Through a specialized team, the Company monitors hardwood pulp prices and analyses future trends, adjusting the forecasts aimed at assisting with preventive measures to calculate the different scenarios. There is no sufficiently liquid financial market to mitigate the risk of a material portion of the Company's operations. Hardwood pulp price protection instruments available on the market have low liquidity and low volume, and high levels of distortion in price formation.

The Company is also exposed to international oil prices, reflected in logistical costs for selling in the export market, and indirectly in the costs of other supply, logistics and service contracts. In such cases, the Company evaluates whether to contract derivative financial instruments to mitigate the risk of price variations in its results.

**4.5 Derivative financial instruments**

The Company determines the fair value of derivative contracts, which differ from the amounts realized in the event of early settlement due to bank spreads and market factors at the time of quotation. The amounts presented by the Company are based on an estimate using market factors and use data provided by third parties, measured internally and compared to calculations performed by external consultants and by counterparties.

The fair value does not represent an obligation to make an immediate disbursement or receipt of cash, given that such an effect will only occur on the dates of contractual fulfillment or upon the maturity of each transaction, when the result will be determined, depending on the case and on the market conditions on the agreed dates.

A summary of the methodologies used for the purpose of determining the fair value by type of instrument is presented below:

&nbsp;&nbsp;&nbsp;&nbsp;(i)Swaps: the future value of the asset and liability is estimated based on the cash flows projected using the market interest rate of the currency in which the tip of the swap is denominated. The present value of the US Dollar-denominated tip is measured using the discount based on the exchange coupon curve (the remuneration, in US Dollars, of the Reais invested in Brazil) and in the case of the R$-denominated tip, the discount is made using Brazil's interest curve, being the future curve of the DI, considering the credit risk of both the Company and the counterparty. The exception is pre-fixed contracts x US$, for which the present value of the tip denominated in US$ is measured through a discount using the SOFR curve disclosed by Bloomberg. The fair value of the contract is the difference between these two points. Interest rate curves were obtained from B3.

&nbsp;&nbsp;&nbsp;&nbsp;(ii)Options (Zero Cost Collar): the fair value was calculated based on the Garman Kohlhagen model, considering both the Company's and the counterparty credit risk. Volatility information and interest rates are observable and obtained from the B3 exchange and are used to calculate the fair values.

&nbsp;&nbsp;&nbsp;&nbsp;(iii)Non-deliverable forward ("NDF") contracts: a projection of the future currency quote is made, using the exchange coupon curves and the future DI curve for each maturity. Next, the difference between this quotation and the rate at which the operation was contracted is verified, considering the credit risk of the Company and the counterparty. This difference is multiplied by the notional value of each contract and brought to its present value based on the future DI curve. Interest rate curves were obtained from B3.

&nbsp;&nbsp;&nbsp;&nbsp;(iv)Swap US-CPI: liability cash flows are projected based on the US inflation curve US-CPI, obtained based on the implicit rates for inflation-linked US securities (Treasury Protected against Inflation – "TIPS"), disclosed by Bloomberg. Cash flows from the asset components are projected at the fixed rates implicit in the embedded derivatives. The fair value of an embedded derivative is the difference between the two components, adjusted to present value base on the curve of the exchange coupon obtained from B3.

&nbsp;&nbsp;&nbsp;&nbsp;(v)Swap VLSFO (marine fuel): a future projection of the asset price is made, using the future price curve disclosed by Bloomberg. Next, the difference between this projection and the rate at which the operation was contracted is verified, considering both of Company's and the counterparty's credit risk. This difference is multiplied by the notional value of each contract and adjusted to present value using the SOFR curve disclosed by Bloomberg.

The yield curves used to calculate the fair value as of December 31, 2025 are as set forth below:

(1)The embedded derivative refers to a swap contract for the sale of price variations in US$ and US-CPI within the term of a forest partnership with a standing wood supply contract.

The current contracts and the respective protected risks are set forth below:

&nbsp;&nbsp;&nbsp;&nbsp;(i)Swap CDI x Fixed US$: positions in conventional swaps exchanging the variation of the Interbank Deposit rate ("DI") for a fixed rate in US$. The objective is to change the debt indexed in Brazilian Reais to US$, in compliance with the Company's natural exposure to US$ receivables.

&nbsp;&nbsp;&nbsp;&nbsp;(ii)Swap IPCA x CDI (notional in Brazilian Reais): positions in conventional swaps exchanging the variation of the Amplified Consumer Price Index ("IPCA") for the DI rate. The objective is to change the debt indexed in reais, in compliance with the Company's cash position in Brazilian Reais, which is also indexed to DI.

&nbsp;&nbsp;&nbsp;&nbsp;(iii)Swap SOFR x Fixed US$: positions in conventional swaps exchanging a post-fixed rate (SOFR) for a fixed rate in US$. The objective is to protect the cash flow against changes in the US interest rate.

&nbsp;&nbsp;&nbsp;&nbsp;(iv)Pre-Fixed Swap R$ x Fixed US$: positions in conventional swaps of a fixed rate in Reais for a fixed rate in US$. The objective is to change the exposure of debts in Brazilian Reais to US$, in compliance with the Company's natural exposure to US$ receivables.

&nbsp;&nbsp;&nbsp;&nbsp;(v)SOFR x SOFR Swap: swap position exchanging a fixed rate added to SOFR for another fixed rate added to SOFR. The objective is to generate a fee discount for Prepayment with the banking institution, allowing for reversal mechanisms.

&nbsp;&nbsp;&nbsp;&nbsp;(vi)CDI x SOFR Swap: positions in conventional swaps exchanging the variation in the Interbank Deposit rate ("DI") for a post-fixed rate ("SOFR") US$. The objective is to change the debt index in reais to US$, aligning with the natural exposure of the Company's US$ receivables and capturing a lower cost of debt through the fluctuation of SOFR rate projections.

&nbsp;&nbsp;&nbsp;&nbsp;(vii)*Swap* CNH x USD: swap positions exchanging a fixed rate in Chinese yuan for a fixed rate in US$. The objective is to change the exposure of debts in yuan to US$, aligning with the natural exposure of the Company's receivables in US$.

&nbsp;&nbsp;&nbsp;&nbsp;(viii)Zero Cost Collar: positions in an instrument that consists of the simultaneous combination of a purchase of put options and the sale of call options in US$, with the same principal amount and maturity, with the objective of protecting the cash flow of exports. Under this strategy, an interval is established where there is no deposit or receipt of financial margin at the option maturity. The objective is to protect the cash flow of exports against the depreciation of the Brazilian Real.

&nbsp;&nbsp;&nbsp;&nbsp;(ix)Non-Deliverable Forward contracts ("NDF"): short positions in US$ futures contracts with the objective of protecting the cash flow from exports against the depreciation of the Brazilian Real.

&nbsp;&nbsp;&nbsp;&nbsp;(x)Swap US-CPI: The embedded derivative refers to the swap contracts for selling price variations in US$ and the US-CPI in forest partnership with a standing wood supply contract.

&nbsp;&nbsp;&nbsp;&nbsp;(xi)Non-Deliverable Forward contracts: EUR and US$: call positions at EUR/US$ parity to protect the Capex cash flow of the Cerrado project against the appreciation of the Euro.

&nbsp;&nbsp;&nbsp;&nbsp;(xii)Swap Very Low Sulphur Fuel Oil / Brent ("VLSFO"): Long positions in oil, aimed at hedging logistical costs related to maritime freight contracts against the increase in oil prices.

&nbsp;&nbsp;&nbsp;&nbsp;(xiii)Zero Cost Collar (Brent): positions in an instrument that consists of the simultaneous combination of buying call options and selling put options for oil - Brent, with the same principal value and maturity, with the objective of protecting input costs of oil derivatives. In this strategy, an interval is established where there is no deposit or receipt of financial margin at the expiration of the options. The objective is to protect costs against rising oil prices.

The variation in the fair values of derivatives on December 31, 2025 compared to the fair values measured on December 31, 2024 are explained substantially by the appreciation of the Brazilian Real against the US$ and by settlements during the year.

There were also impacts caused by the variations in the Pre Fixed, Foreign Exchange Coupon and SOFR curves in the operations.

It is important to highlight that the outstanding agreements on December 31, 2025 are over-the-counter market operations, without any type of collateral margin or forced early settlement clause due to variations from market marking.

**4.6 Fair value hierarchy**

Financial instruments are measured at fair value, which considers the fair value as the price that would be received from selling an asset or paid to transfer a liability in an unforced transaction between market participants at the measurement date.

Depending on the inputs used for measurement, the financial instruments at fair value may be classified into three hierarchical levels:

&nbsp;&nbsp;&nbsp;&nbsp;(i)Level 1 – Based on quoted prices (unadjusted) for identical assets or liabilities in active markets. A market is considered active if it trades frequently and at a sufficient volume to provide pricing information immediately and continuously, usually obtained from a commodity and stock exchange, pricing service or regulatory agency, and if the prices represent actual market transactions, which occur regularly on a commercial basis;

&nbsp;&nbsp;&nbsp;&nbsp;(ii)Level 2 - Based on the prices quoted in active markets for similar assets or liabilities, the prices quoted for identical or similar assets or liabilities in non-active markets, evaluation models for which inputs are observable , such as rates of interest and yield curves, credit volatilities and spreads, and market corroborated information. Assets and liabilities classified in this category are measured based on the discounted cash flow and interest accrual, respectively, for derivative financial instruments and marketable securities. The observable inputs include interest rates and curves, volatility factors and foreign exchange rates; and

&nbsp;&nbsp;&nbsp;&nbsp;(iii)Level 3 – Based on unquoted data for assets and liabilities, where the Company applies the income approach technique using the discounted cash flow model. The observable inputs used are the IMA, discount rate and eucalyptus average gross sales price.

For the year ended December 31, 2025, there were no changes between the levels of hierarchy and no transfers between levels 1, 2 and 3.

**4.7 Cybersecurity**

Suzano has a Public Information Security Policy, which aims to establish guidelines regarding cyber security management and controls at Suzano, seeking to mitigate vulnerabilities, preserve and protect assets, mainly information and personal data, in accordance with current laws, regulations and contractual obligations, covering the confidentiality, integrity, availability, authenticity and legality of information. The Policy establishes responsibilities to avoid damages, which may represent financial impacts, image and reputation, exposure of information, interruption of operations, among other damages due to cyber-attacks.

For the year ended December 31, 2025, no material incidents associated with cybersecurity were identified that could affect the confidentiality, integrity and/or availability of the systems used by the Company.

**4.8 Climate change**

**4.8.1 Risks linked to climate change and the sustainability strategy**

In view of the nature of the Company's operations, there is inherent exposure to risks related to climate change.

The Company's assets, notably biological assets, which are measured at fair value (Note 13), property, plant and equipment (Note 15) and intangible assets (Note 16), may be impacted by climate change, the risks of which were evaluated in the context of preparation of financial statements. For the year ended December 31, 2025, Management considered the main risk data and assumptions highlighted below:

&nbsp;&nbsp;&nbsp;&nbsp;(i)Possible impacts on the determination of fair value in biological assets due to: Effects of climate change, such as temperature rises and scarcity of water resources, could impact some of the assumptions used in accounting estimates related to the Company's biological assets, as follow:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Loss of biological assets due to fires and impacts arising from the greater presence and resistance of pests and other forest diseases favored by the gradual increase in temperature;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Reduction in productivity and expected growth ("IMA") due to reduced availability of water resources in river basins and other atypical weather events such as droughts, frosts and torrential rains; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Interruptions to the production chain due to adverse weather events.

&nbsp;&nbsp;&nbsp;&nbsp;(ii)Scarcity of water resources in the industry: although our units are efficient in the use of water, there are contingency plans for all units affected by possible water shortages and action plans to confront the water crisis in critical regions.

&nbsp;&nbsp;&nbsp;&nbsp;(iii)Structural changes in society and their impacts on business, such as:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Regulatory and legal: arising from changes in the Brazilian and/or international scope that require capital investment in new technologies and/or operating costs. Among the expected topics are carbon pricing, customs carbon taxation, trade barriers and/or commercial restrictions related to businesses' alleged contributions, even if indirect, to the intensification of climate change, which increase the risk of litigation;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Technological: arising from the emergence of improvements and innovations towards an economy with greater energy efficiency and lower carbon. Suzano should continue investing in technology to reduce greenhouse gas emissions;

---

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Markets: arising from changes to the supply of and demand for certain products and services as climate-related issues begin to be considered in decision-making. The market should increasingly prioritize the reduction of carbon emissions and more sustainable business practices, which may lead to changes in demand for and revenues from Suzano's products and an increase in demand for renewable forests and other sustainable products; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Reputational: related to the perceptions of customers and society in general regarding the positive or negative contribution of an organization to a low carbon economy.

The Company carries out factoring transactions for certain customer receivables where it transfers the control of all risks and rewards related to these receivables to the counterparty, so these receivables are derecognized from accounts receivable in the balance sheet. This transaction refers to an additional cash generation opportunity which can be discontinued at any time without significant impacts on the Company's operation and is therefore classified as a financial asset measured at amortized cost. The decision to assign the receivables is continuously reassessed based on market conditions and the Company's cash flow strategy, meaning that the volume of discounts may vary over time. The impact of these factoring transactions on the accounts receivable as of December 31, 2025, was R$6,616,450 (R$6,821,539 as of December 31, 2024).

The forestry development program consists of an incentive partnership for regional forest production, where independent producers plant eucalyptus on their own land to supply agricultural wood products to the Company. Suzano provides eucalyptus seedlings, input subsidies and cash advances, and the latter are not subject to valuation at their present value since they will be settled in volume standing or cut wood. In addition, the Company supports producers by providing technical advice on forest management but does not have joint control over decisions effectively implemented. At the end of the production cycles, the Company has a contractually guaranteed right to make an offer to purchase the forest and/or wood at its market value. However, this right does not prevent producers from negotiating the sale of the forest and/or wood with other market participants, provided the incentive amounts are fully paid.

**12 INCOME AND SOCIAL CONTRIBUTION TAXES**

The Company management believes in the validity of the provisions of international treaties entered by Brazil to avoid double taxation. In order to ensure its right to non-double taxation, the Company filed a lawsuit in April 2019, which aims to exempt the double taxation in Brazil, of profits earned by its subsidiary located in Austria, according to Law No. 12,973/14. Due to the preliminary injunction granted in favor of the Company in the aforementioned lawsuit, the Company decided not to add the profit from Suzano International Trading GmbH, located in Austria, when determining its taxable income and social contribution basis of the net profit of the Company for the year ended December 31, 2025. There is no provision for tax related to the non-double taxation profits of such subsidiary in 2025. Disclosures about uncertain tax positions for income tax and social contribution (IFRIC 23) are presented in Note 20.2.

**12.3 Tax incentives**

The Company benefits from a tax incentive for partial reduction of the income tax obtained from operations carried out in areas under the jurisdiction of the Northeast Development Superintendence ("SUDENE") and the Superintendence of Amazon Development ("SUDAM"). The IRPJ reduction incentive is calculated based on the activity profits (exploitation profits) and considers the allocation of the operating profit based on the incentive production levels for each product.

**12.4 OECD PILLAR TWO MODEL RULES**

In December 2021, the Organisation for Economic Co-operation and Development ("OECD") announced the guidelines for the Pillar Two model, aiming for a reform in international corporate taxation to ensure that multinational economic groups, covered by such regulations, contribute an effective minimum tax at a rate of 15% on profits. Each country's effective profit tax rate, as calculated by this model, is called the GloBE (Global Anti-Base Erosion Rules) effective tax rate. These rules await approval in the local legislation of each country. In the context of Suzano, compliance with OECD guidelines on international taxation is a strategic priority.

Many countries have already released legislation or plans on the adoption of Pillar Two rules and the calculation of GloBE revenue, considering the global minimum rate of 15% for multinationals with consolidated revenue above EUR750 million.

Since 2024, the Company has been subject to these new rules in certain European jurisdictions where it operates, with Austria standing out as a relevant operation.

As of 2025, the Company is subject to the Additional Social Contribution on Net Income (CSLL), which is the Brazilian legislation's response to the GloBE rules and affects business groups with an IRPJ and CSLL tax burden of less than 15% in Brazil.

Based on the calculations performed under the GloBE Simplifying Transition Rules (RSGT), there is no impact on the financial statements in relation to this matter.

The Company reaffirms its commitment to tax compliance and will continue to carry out the necessary actions to ensure the proper implementation of the new rule in the jurisdictions where it operates, in line with global best practices and current legislation.

**13 BIOLOGICAL ASSETS**

The roll-forward of biological assets is as set forth below:

---

| | | |
|:---|:---|:---|
| | **12/31/2025** | **12/31/2024** |
| **Opening balance** | **22283001** | 18278582 |
| &nbsp;&nbsp;&nbsp;&nbsp;Additions | **7913483** | 7180450 |
| &nbsp;&nbsp;&nbsp;&nbsp;Additions of merged companies |  | 366785 |
| &nbsp;&nbsp;&nbsp;&nbsp;Depletions | **(5352271)** | (4831916) |
| &nbsp;&nbsp;&nbsp;&nbsp;Transfers | **15233** | 102790 |
| &nbsp;&nbsp;&nbsp;&nbsp;Gain on fair value adjustments (Note 29) | **1516458** | 1431530 |
| &nbsp;&nbsp;&nbsp;&nbsp;Disposals | **(107815)** | (130922) |
| &nbsp;&nbsp;&nbsp;&nbsp;Write-offs | **(170925)** | (114298) |
| **Closing balance** | **26097164** | **22283001** |

---

The calculation of fair value of the biological assets is determined using unobservable data, therefore it falls under Level 3 in the hierarchy set forth in IFRS 13 — Measurement of Fair Value.

In our model, the assumptions regarding the average annual growth rate (IMA) and average gross selling price of eucalyptus are particularly sensitive. Any increase or decrease in these assumptions could lead to significant gains or losses in the fair value measurement.

The assumptions used in the measurement of the fair value of biological assets were as follow:

&nbsp;&nbsp;&nbsp;&nbsp;(i)Average cycle of forest formation between 6 and 7 years;

&nbsp;&nbsp;&nbsp;&nbsp;(ii)Effective area of forest from the 3rd year of planting;

&nbsp;&nbsp;&nbsp;&nbsp;(iii)The IMA consists of the estimated volume of production of wood with bark in m<sup>3</sup> per hectare, ascertained based on the genetic material used in each region, silvicultural practices and forest management, production potential, climate factors and soil conditions;

&nbsp;&nbsp;&nbsp;&nbsp;(iv)The estimated average standard cost per hectare includes silvicultural and forest management expenses, applied to each year of formation of the biological cycle of the forests, plus the costs of land lease agreements and the opportunity cost of owning land;

&nbsp;&nbsp;&nbsp;&nbsp;(v)The average gross selling prices of eucalyptus were based on specialized research on transactions carried out by the Company with independent third parties; and

&nbsp;&nbsp;&nbsp;&nbsp;(vi)The discount rate corresponds to the Weighted Average Cost of Capital ("WACC").

**16 INTANGIBLE**

(1)Refers to other intangible assets with indefinite useful lives such as servitude of passage and electricity.

The goodwill is based on expected future profitability supported by valuation reports, after the purchase price allocation.

Goodwill is allocated to cash-generating units as presented in Note 28.4.

For the pulp cash-generating unit ("CGU"), the calculation of the value in use of non-financial assets is performed annually using the discounted cash flow method. In 2025 the Company used the strategic plan and the annual budget with projected increases to 2029 and the average rate in perpetuity of the cash generating units considering a nominal rate of 3.63% p.a. from this date, based on historical information for previous years, economic and financial projections from each specific market in which the Company has operations, and additionally include official information disclosed by independent institutions and government agencies.

The discount rate, after taxes, adopted by Management was 8.87% p.a., calculated based on the Weighted Average Cost of Capital ("WACC").

The assumptions in the table set forth below were also adopted:

---

| | |
|:---|:---|
| **Net average pulp price – Foreign market (US$/t)** | **634.3** |
| **Net average pulp price – Internal market (US$/t)** | **681.4** |
| **Average exchange rate (R$/US$)** | **5.46** |
| **Discount rate (pos-tax)** | **8.87% p.a.** |
| **Discount rate (pre-tax)** | **12.30% p.a.** |

---

For the year ended December 31, 2025, the Company did not identify the need to record any impairment provision for intangible assets.

For the Paper Cash-Generating Unit ("CGU"), the recoverability test of assets is performed annually based on the estimated fair value less costs of disposal, determined through the application of EV/EBITDA market multiples, considering comparable companies in the same industry and the specific characteristics of the Company's operations. Based on the analyses performed by the Company, no adjustment to reduce the carrying amounts of the assets to their recoverable amount (impairment) was identified in 2025.

If the post-tax discount rate applied to the cash flow projections of both cash-generating units had been 1% higher than management's estimates (9.87% instead of 8.87%), the Company still would not need to recognize an impairment provision.

The Company assessed possible changes in price and exchange rate assumptions and did not identify any scenarios that would cause the carrying amount of the cash-generating units to exceed their recoverable amount.

**20.1.2 Labor**

On December 31, 2025, the Company has 1,152 (1,178 as of December 31, 2024) labor lawsuits.

In general, the provisioned labor proceedings are related primarily to matters frequently contested by employees of agribusiness companies, such as wages and/or severance payments, in addition to suits filed by outsourced employees of the Company.

**20.1.3 Civil, environment and real estate**

On December 31, 2025, the Company has 73 (97 as at December 31, 2024) civil, environmental and real estate proceedings.

The provisioned Civil, environment and real estate proceedings are related primarily to the payment of damages, including those arising from contractual obligations, traffic-related injuries, possessory actions, environmental restoration obligations, claims and others.

**20.2 Contingencies with possible losses**

The Company is involved in tax, civil and labor lawsuits, whose losses have been assessed as possible by Management, supported by legal counsel, and therefore no provision was recorded:

---

| | | |
|:---|:---|:---|
| | **12/31/2025** | **12/31/2024** |
| Taxes and social security <sup>(1)</sup> | **10417734** | 9837082 |
| Labor | **189506** | 171480 |
| Civil and environmental <sup>(1) (2)</sup> | **1023689** | 5065714 |
|  | **11630929** | **15074276** |

---

(1)The amounts above do not include the fair value adjustments allocated to possible loss risk contingencies representing R$R$2,076,296 (R$2,108,635 as of December 31, 2024), which were recorded at fair value resulting from business combinations with Fibria, as presented in Note 20.1.1 above.

(2)The Company is a defendant in a Public Civil Action ("ACP") regarding compensation for damages caused to federal highways due to the transportation of timber exceeding the permitted weight. Based on a recent decision by the Superior Court of Justice ("STJ"), which established the thesis of civil liability without clear and objective liquidation criteria, as well as the change of the monetary correction index from IGPM/FGV to SELIC, the Company reassessed the exposure amount of this action to approximately R$352,442. This estimate made by management and supported by its external legal advisors, is based on scenarios with similarity to infraction notices suffered by other companies and assessed according to the quantification criteria applied by the Federal Public Ministry ("MPF"). Given the absence of clear and objective criteria for measuring such claims from the MPF in similar cases, management's current estimate may vary to a higher or lower amount, subject to the final decision by the MPF/TRF1 regarding the Company's case.

**20.2.1 Tax and social securities**

For the year ended December 31, 2025, the Company had 631 (673 as of December 31, 2024) tax proceedings whose likelihood of loss is considered possible, in the total amount of R$10,417,734 (R$9,837,082 as of December 31, 2024) for which no provision was recorded.

The other tax and social security lawsuits involve various taxes, such as IRPJ, CSLL, PIS, COFINS, ICMS, ISS, IRRF. These disputes primarily arise from differing interpretations of the applicable tax regulations and the information provided in the ancillary obligations.

The most significant tax cases are outlined below:

&nbsp;&nbsp;&nbsp;&nbsp;(i)Income Tax Assessment - IRPJ/CSLL - Swaps of Industrial and Forestry Assets: In December 2012, the Company received a tax assessment for income tax and social contribution, alleging unpaid tax on a capital gain in February 2007, the closing date of the transaction, when the Company executed an agreement with International Paper regarding a swap of industrial and forestry assets. On January 19, 2016, the Tax Federal Administrative Court ("CARF") rejected, as per the casting vote of the CARF's President, the appeal filed by the Company in the administrative process. The Company was notified of the decision on May 25, 2016 and, given the impossibility of further appeals and the consequent closure of the case at the administrative level, decided to pursue the discussion in the Judiciary. The lawsuit was ruled in favor of the Company's interests and the National Treasury's appeal is currently awaiting judgment at the lower court. In December 2023, pursuant to article 25, § 9ºA, of Law No. 14,689/23, the Active Debt Certificates were rectified to definitively cancel the amounts related to the tax assessment penalty and its charges. According to the Company and its external legal advisors the probability of loss in this case is possible, except for the provisioning of the amount equivalent to the contingent liability assumed arising from the business combination. For the year ended December 31, 2025, the estimated amount of the possible exposure is R$1,861,899 (R$1,688,690 as of December 31, 2024).

&nbsp;&nbsp;&nbsp;&nbsp;(ii)Income tax assessment - IRPJ/CSLL: This refers to an administrative proceeding initiated in October 2023, resulting from tax assessments for IRPJ and CSLL issued against Suzano S.A., for the calendar year of 2019. The infractions alleged include: (i) nondeductible expenses; (ii) improper deduction of operating expenses; (iii) profits earned by the subsidiaries abroad; (iv) goodwill amortization; (v) lack of addition of bonus paid to directors to the CSLL calculation basis, and (vi) tax loss and negative CSLL basis. The Company filed an administrative objection, which was partially upheld. Currently, the Company filed a voluntary appeal, which was partially granted. The issuance of the decision is currently awaited. In the Company's opinion, supported by the opinions of its external legal counsel, the likelihood of loss in the case is assessed as possible. For the year ended December 31, 2025, the total amount of the possible exposure is R$1,008,823 (R$920,628 as of December 31, 2024).

&nbsp;&nbsp;&nbsp;&nbsp;(iii)Income Tax Assessment - IRPJ/CSLL - Disallowance of Depreciation, Amortization and Depletion Expenses – 2010 period: In December 2015, the Company received a tax assessment demanding the payment of IRPJ and CSLL. The assessment challenges the deductibility of depreciation, amortization and depletion expenses of 2010, which the Company had included in its income tax calculations. The Company filed an administrative appeal, which was partially upheld. This decision was subject to a voluntary appeal, filed by the Company in November 2017. The judgment was converted into a due diligence process, and currently, the Company is awaiting the completion of the due diligence. In the Company's opinion, supported by the opinions of its external legal counsel, the likelihood of loss in the case is assessed as possible. For the year ended December 31, 2025 the total amount of the possible exposure is R$931,979 (R$875,466 as of December 31, 2024).

&nbsp;&nbsp;&nbsp;&nbsp;(iv)Tax Assessment - IRPJ/CSLL: On October 5, 2020, the Company was notified of a Tax Assessment issued by the Brazilian Internal Revenue Service ("RFB") claiming the payment of IRPJ and CSLL credits, resulting from the remeasurement of the profit of its subsidiary Suzano Trading Ltd in the years ended December 31, 2014, 2015 and 2016. Based on the legal advisors hired to present the defense, the Company classifies, the risk of loss as possible with reference to the Company and, with reference to the Officers, also possible but with a higher chance of winning (possible to remote). The Company presented the administrative defense and, currently, the judgment was converted into a diligence. The objection was judged partially upheld, and the company will file a voluntary appeal regarding the portion that was unfavorable. In the Company's opinion, supported by the opinions of its external legal counsel, the likelihood of loss in the case is assessed as possible. In the year ended December 31, 2025 the total amount of the possible exposure is R$663,188 (R$609,548 as of December 31, 2024).

&nbsp;&nbsp;&nbsp;&nbsp;(v)PIS/COFINS – Goods and Services – Period of 2009 to 2011: In December 2013, the Company was assessed by the RFB demanding the collection of PIS and COFINS credits disallowed for allegedly not being linked to its operational activities. In the first instance, the objection filed by the Company was dismissed. A voluntary appeal was filed and it was partially upheld in April 2016. From this decision, the Company filed a special appeal, and certain divergences were admitted for consideration by the Superior Chamber of Tax Appeals ("CSRF"). The National Treasury also filed a special appeal with the Superior Chamber. The CSRF denied the National Treasury's appeal and partially granted the Company's appeal. The issuance of the CSRF's decision is currently awaited. In the Company's opinion, supported by the opinions of its external legal counsel, the likelihood of loss in the case is assessed as possible. For the year ended December 31, 2025 the total amount of the possible exposure is R$213,286 (R$201,199 as of December 31, 2024).

&nbsp;&nbsp;&nbsp;&nbsp;(vi)Tax incentive - Agency for the Development of Northeastern Brazil ("ADENE"): In 2002, the Company applied for and was granted by the RFB the right to benefit from a reduction in the IRPJ and non-refundable additional taxes calculated on operating profit, for plants A and B (period from 2003 to 2013) and plant C (period from 2003 to 2012), all located in the Aracruz unit, under the condition of making new investments in its units located in the area covered by ADENE. In 2004, the Company received a notice from the extrajudicial administrator of the extinct Superintendency for the Development of the Northeast ("SUDENE"), informing it that the right to enjoy the benefit previously granted was deemed unfounded and would be revoked. In 2005, a tax assessment was issued demanding alleged amounts relating to the tax incentive enjoyed up to that point. After administrative discussion, the tax assessment was partially upheld recognizing the Company's right to benefit from the tax incentive until 2003. The Company's management, advised by its legal advisors, believes that the decision to cancel the referred tax benefits is incorrect and should not prevail, whether concerning the benefits already enjoyed or those not yet enjoyed until their respective final terms. Currently, the contingency is being discussed in the judicial sphere. The Company is awaiting the judgment of the appeal filed against the unfavorable decision. In the Company's opinion, supported by the opinions of its external legal counsel, the likelihood of loss in the case is assessed as possible. For the year ended December 31, 2025 the total amount of the possible exposure is R$159,012 (R$150,869 as of December 31, 2024).

&nbsp;&nbsp;&nbsp;&nbsp;(vii)Offsetting - IRRF - Period 2000: The Company filed a process to offset IRRF credits for the year ended December 31, 2000 against debts owed to the RFB. In April 2008, the Brazilian Federal Revenue Service partially recognized the credit in favor of the Company. The Company filed a Voluntary Appeal with CARF against this decision and the judgment was converted into a due diligence process. In the judgment rendered at the second administrative instance, the Company's appeal was partially granted. We are currently awaiting the issuance of the decision. In the Company's opinion, supported by the opinions of its external legal counsel, the likelihood of loss in the case is assessed as possible. For the year ended December 31, 2025 the total amount of the possible exposure is R$130,895 (R$125,489 as of December 31, 2024).

&nbsp;&nbsp;&nbsp;&nbsp;(viii)IRPJ/CSLL - Partial Approval – 1997 Period: The Company filed a process to offset credits arising from tax losses for the year 1997 against debts owed to the RFB . In March 2009, the tax authorities approved only R$83,000, resulting in a difference of R$51,000. The Company is still awaiting the conclusion of the analysis of the credits under administrative review following a favorable decision by CARF in August 2019, which upheld the voluntary appeal filed by the Company. For the remaining portion of the credit, the Company filed a lawsuit to discuss the matter which is currently awaiting judgment in the second instance of its appeal, filed after an unfavorable ruling. In the Company's opinion, supported by the opinions of its external legal counsel, the likelihood of loss in the case is assessed as possible. For the year ended December 31, 2025, the total amount of the possible exposure is R$128,393 (R$122,319 as of December 31, 2024).

&nbsp;&nbsp;&nbsp;&nbsp;(ix)Tax Assessment - IRPJ/CSLL: Administrative proceeding demanding the collection of IRPJ and CSLL for the 2015 calendar year. The infractions alleged include (i) transfer pricing; and (ii) non-deductible expenses. The Company filed an objection in January 2020, which was partially upheld. Following this decision, the Company filed a voluntary appeal, and the judgment was converted into a due diligence process. The appeal is currently pending judgment. In the Company's opinion, supported by the opinions of its external legal counsel, the likelihood of loss in the case is assessed as possible. For the year ended December 31, 2025, the total amount of the possible exposure is R$121,327 (R$112,168 as of December 31, 2024).

&nbsp;&nbsp;&nbsp;&nbsp;(x)IRPJ/CSLL - Partial Approval – 2000 Period: In 2024, the Company submitted a request to offset credits arising from the negative balance calculated in the year 2000 against debts owed to the Brazilian Federal Revenue Service ("RFB"). The RFB fully disallowed the tax credit. After presenting the defense and the appropriate appeals, the process ended unfavorably for the Company at the administrative level. The Attorney General's Office of the National Treasury ("PGFN") filed a tax execution to collect the amounts, at which time the Company filed the appropriate motions to stay the tax execution, which were partially upheld. The Company has filed an Appeal, which is awaiting judgment. In the Company's opinion, supported by the opinions of its external legal counsel, the likelihood of loss in the case is assessed as possible. For the year ended December 31, 2025, the estimated amount of exposure is R$105,556 (R$101,654 as of December 31, 2024).

&nbsp;&nbsp;&nbsp;&nbsp;(xi)ICMS – Credits – Period 05/2014 to 12/2014: The Company is a party to a tax enforcement action filed by the State of São Paulo for the collection of ICMS related to the period from May 2014 to December 2014. The assessment arises from the alleged failure to reverse ICMS credits linked to the replacement of Electric Energy Invoice Statements originally issued by the power utility, as well as the alleged lack of bookkeeping of the referred invoices related to the entry of electric energy into the facility. After the Company was served, a Surety Bond was submitted and an extension of time was requested for filing the appropriate defenses (appeals against tax enforcement). The Company is currently awaiting notification to file the defenses in the tax enforcement action. In the Company's opinion, supported by the opinions of its external legal counsel, the likelihood of loss in the case is assessed as possible. For the year ended December 31, 2025, the estimated exposure amounts to R$118,867 (R$98,197 as of December 31, 2024).

**20.2.2 Labor**

On December 31, 2025, the Company was a defendant in 1,211 labor lawsuits, totaling R$189,506 (1,135 labor lawsuits, totaling R$171,480 as of December 31, 2024).

The Company also has several lawsuits in which employees' unions in the states of Bahia, Espírito Santo, Maranhão, São Paulo and Mato Grosso do Sul are included.

**20.2.3 Civil, environmental and real estate**

On December 31, 2025, the Company was a defendant in approximately 222 civil, environmental and real estate lawsuits, totaling R$1,023,689 (201 lawsuits totaling R$5,065,714 as of December 31, 2024).

In general, the civil and environmental proceedings in which the Company, including its subsidiaries, is a defendant, are mainly related to discussions regarding eligibility for environmental licenses, repair of environmental damage, matters relating to indemnities, including those arising from discussions about contractual obligations, precautionary measures, possessory actions, damage repair and revision actions, actions aimed at the recovery of credits (collection actions, monitoring, execution, credit qualifications related to bankruptcy and judicial recovery), actions of social movements interest, such as landless workers, quilombola communities, indigenous people and fishers, and actions resulting from traffic accidents. The Company has a general civil liability insurance policy that aims to cover, within the limits contracted in the policy, any legal convictions arising from damages to third parties (including employees).

The most relevant civil cases are set forth below:

&nbsp;&nbsp;&nbsp;&nbsp;(i)The Company is involved in 3 Public Civil Actions ("ACPs") filed by the Federal Public Prosecutor's Office ("MPF") in which it requests (i) an injunction that the Company's trucks stop transporting wood on federal highways above the legal weight restrictions (ii) an increase in the fine for excess weight to be applied to Suzano and (iii) compensation for material damage caused to federal highways, the environment and the economic order and compensation for moral damage. One of the ACPs was judged partially well-founded and the Company filed an appeal to the competent court with a request to suspend the effects of the judgment, which is still pending assessment. The other two lawsuits were dismissed and an appeal is pending. In September 2021, both were suspended due to a decision by the STJ to evaluate the points of discussion in the form of a repetitive appeal. In December 2024, the STJ judged the repetitive appeals to allow the application of a double penalty (administrative and judicial), establishing a thesis authorizing the imposition of injunctive relief and civil liability. Appeals were filed over the past year, without any change to the challenged decision to date. In the Company's opinion, supported by the opinions of its external legal counsel, the likelihood of loss in the case is assessed as possible.

&nbsp;&nbsp;&nbsp;&nbsp;(ii)The company sued a competitor in the central-western region over the improper and unauthorized use of a variety of eucalyptus protected by intellectual property rights (cultivar) of the incorporated subsidiary Fibria. The prohibition on the cultivation of this biological asset by the competitor was protected by an injunction, which was confirmed in a judgment in favor of the Company, with the Company initiating the liquidation of the judgment. However, at the appeal stage and in an extended trial, there was a ruling against the Company recognizing a supposed incidental nullity of the cultivar, a decision that is currently subject to a motion for clarification. It should be noted that, in parallel, there is also a lawsuit in the Federal Court in which the competitor filed an action to annul the registration of the cultivar, but, to date, there has been no decision in this process determining the nullity or restricting the Company's right. In the Company's opinion, supported by the opinions of its external legal counsel, the likelihood of loss in the case is assessed as possible.

&nbsp;&nbsp;&nbsp;&nbsp;(iii)The company sued a competitor in the central-western region over the improper and unauthorized use of a variety of eucalyptus protected by intellectual property rights (cultivar) of the incorporated subsidiary Fibria.

However, at the appeal stage and in an extended trial, there was a ruling against the Company recognizing a supposed incidental nullity of the cultivar. Declaratory Embargos were filed, resulting in the suspension of the action until the final judgment of the annulment lawsuit pending before the Federal Court. A Special Appeal was filed, which was not admitted, leading to the filing of an Interlocutory Appeal (Agravo) against the decision denying the Special Appeal. As mentioned, in parallel, there is a proceeding before the Federal Court in which the competitor filed an action seeking the annulment of the cultivar registration; however, to date, the case is still pending evidentiary production, and there is no decision declaring the registration null or restricting the Company's rights. In the opinion of the Company's external legal counsel, the likelihood of losing the case is possible.

**21 EMPLOYEE BENEFIT PLANS**

The Company provides supplementary pension plan and defined benefit plan, such as medical assistance and life insurance, as set forth below:

**21.1 Pension plan**

The Company has current supplementary retirement plans, as disclosed below.

**21.1.1 Pension plan – Suzano Prev**

In 2005, the Company established the Suzano Prev pension plan, managed by BrasilPrev, an open private pension entity, which serves the employees of Suzano Group Companies, in the form of a defined contribution plan.

Under the terms of the benefit plan agreement, for employees who have a salary above 10 Suzano reference units ("URS"), in addition to the 0.5% contribution, the contributions of the Company matches the employees' contributions, and affect the portion of the salary that exceeds 10 URS, which can vary between 1% and 6% of the nominal salary. This plan is called Basic Contribution 1.

The Company's contributions to the employees are 0.5% of the nominal salary that does not exceed 10 URS, even though there is no contribution by the employees. This plan is called Basic Contribution 2.

From August 2020, employees who have a salary lower than 10 URS will be able to invest 0.5% or 1% of their nominal salary, and the Company will monitor the employee's contributions. The employee can choose to invest up to 12% of their salary in the Suzano Prev pension plan, and the excess of Basic Contribution 1 or 2 may be invested in the supplementary contribution, where there is no counter-entry from the Company, and the employee must consider the two contributions within the limit of 12% of their salary.

Access to the balance constituted by the Company's contributions only occurs upon dismissal, and is directly related to the length of the employment relationship.

Contributions made by the Company, for Suzano Prev pension plan managed by Brasilprev Seguros e Previdência S.A., for the year ended December 31, 2025 amounted R$24,287 (R$21,719 as of December 31, 2024) recognized under the cost of sales, selling and general and administrative expenses.

**21.2 Defined benefits plan**

The Company offers the medical assistance and life insurance in addition to the pension plans, which are measured through actuarial calculations and recognized as personnel expenses in the income statement, as detailed below.

**21.2.1 Medical assistance**

The Company guarantees healthcare program cost coverage for a group of former employees who retired up to 2007, as well as their spouses for life and underage dependents.

For other groups of former employees, who exceptionally, according to the Company's criteria and resolutions or based on rights related to compliance with pertinent legislation, the Company ensures the healthcare program.

The main actuarial risks related are: (i) lower interest rates; (ii) longer than expected mortality tables; (iii) higher than expected turnover; and (iv) higher than expected growth in medical costs.

**22 SHARE-BASED COMPENSATION PLAN**

The Company grants members of the statutory and non-statutory board of directors, key employees and members of the Board of Directors ("Beneficiaries") long-term share-based incentive plans, approved at the General Meeting with the objectives of: (i) aligning the interests of the beneficiaries with the interests of the Company and its shareholders, (ii) attracting, rewarding, retaining and incentivizing the beneficiaries to conduct the Company's business in a sustainable manner, within appropriate risk limits and aligned with the interests of the shareholders, and (iii) granting a financial incentive to the beneficiaries.

The plans granted by the Company are: (i) Phantom Shares Plan ("PS"), settled in in local currency and (ii) Restrict Shares Plan ("Performance Shares"), settled in shares.

The characteristics and measurement criteria of each plan are disclosed below:

**22.1 Phantom shares plan**

The number of phantom shares to be granted to each beneficiary is calculated based on a financial amount per beneficiary.

The beneficiary may only exercise the rights to the phantom shares once the vesting period has been completed, lasting up to 5 (five) years from the date of grant, in accordance with the characteristics of each plan.

The settlement of the phantom shares is in cash, and the amount will be calculated by multiplying the number of shares granted by the value of the share measured based on the average price of the last 90 (ninety) trading sessions, adjusted, when applicable, for the Company's Total Shareholder Return ("TSR"), in accordance with the criteria established in each plan.

The TSR represents a market condition and its effects are incorporated into the fair value measurement of the phantom shares at the grant date.

Since phantom share plans are settled in cash, their fair values are measured at the end of each reporting period.

(1)For the year ended December 31, 2025, the average price of the share options exercised, including exercises resulting from termination of employment, was R$56.57.

**22.2 Restricted shares plan**

Each performance share corresponds to 1 (one) common, registered, book-entry share with no par value issued by the Company, to be delivered to the beneficiary once the conditions established in this plan have been met.

The acquisition of rights to the beneficiaries is subject to: (i) continued permanence of the beneficiaries as directors of the Company during the vesting period, (ii) achievement of the goals assigned in the programs and (iii) any other conditions determined by the Board of Directors in each grant made.

The vesting period may last up to 5 (five) years, starting from the date of grant, according to the characteristics of each plan.

The number of performance shares to be effectively delivered to each beneficiary will depend on the achievement of the goals linked to the respective programs and contracts, and will be determined after the vesting period. This calculation will also consider the Total Shareholder Return ("TSR"), which is an indicator used to measure the performance of the shares of the group of companies characterized as competitors of Suzano.

If beneficiaries leave the Company before fulfilling the conditions for obtaining rights, they lose the right to exercise the restricted share option.

**24.3 Reserves**

**24.3.1 Capital reserve**

They consist of amounts received by the Company arising from transactions with shareholders that do not pass through the income statement and may be used to absorb losses when they exceed profit reserves and redemptions, reimbursements and purchases of shares.

**24.3.2 Income reserves**

Reserves are constituted by the allocation of the Company's profits, after the allocation for the payment of the minimum mandatory dividends and after the allocation to the various profit reserves, as set forth below:

&nbsp;&nbsp;&nbsp;&nbsp;(i)Legal: established based on 5% (five percent) of the net profit of each fiscal year, in accordance with Article 193 of Brazilian Law No. 6,404/76, and limited to 20% (twenty percent) of the share capital. In any year in which the balance of the legal reserve, combined with the amounts of capital reserves, exceeds 30% (thirty percent) of the share capital, the allocation of a portion of net income to the legal reserve will not be mandatory. The use of this reserve is restricted to offsetting losses and increasing share capital, aiming to ensure the integrity of the share capital. For the year ended December 31, 2025, the balance of this reserve was R$2,517,519 (R$1,847,109 as of December 31, 2024).

&nbsp;&nbsp;&nbsp;&nbsp;(ii)Capital increase: established based on up to 90% (ninety percent) of the remaining balance of net income for the year, limited to 80% (eighty percent) of the share capital, pursuant to the Company's bylaws, after the allocation to the legal reserve and the minimum mandatory dividends. The purpose of this reserve is to ensure the Company maintains adequate operating conditions. For the year ended December 31, 2025, the Company allocated R$2,807,632 to the capital increase (Note 1.2.2), ending the year with a balance of R$10,128,485 (R$2,807,632 as of December 31, 2024).

&nbsp;&nbsp;&nbsp;&nbsp;(iii)Special statutory: established based on 10% (ten percent) of the remaining balance of net income for the year, with the purpose of ensuring the continuity of dividend distribution, up to the limit of 20% (twenty percent) of the share capital. For the year ended December 31, 2025, the balance of this reserve was R$2,972,996 (R$1,847,109 as of December 31, 2024).

&nbsp;&nbsp;&nbsp;&nbsp;(iv)Tax incentives: established under the terms of Article 195-A of Law No. 6,404/76, as amended by Law No. 11,638/07 and based on a proposal from the Company's management bodies. The Company allocates the portion of net income arising from donations or government subsidies to investments, and this portion is excluded from the basis for calculating the mandatory minimum dividend. For the year ended December 31, 2025, the balance of this reserve was R$1,534,462 (R$1,319,908 as of December 31, 2024). This increase is due to the constitution of reserves related to the benefits of Exploration Profit (note 12.3) and Reinvestment. Exploration Profit, applicable to the manufacturing units located in the states of Espírito Santo, Maranhão, and Bahia (under Sudene's approval), as well as the plant in Belém do Pará (under Sudam's approval), contributed to a reserve of R$214,555 in the year ended December 31, 2025. Regarding the Reinvestment incentive, there was no use of this benefit during the year, which explains the maintenance of the reserve at R$14,574, related to the previous year. s for the investment subsidy tax incentive, in accordance with Law No. 14,789/2023, the Company taxed the results equivalent to these amounts, and no new reserve was constituted for this tax incentive in the current year. Only the maintenance of the reserve in the amount of R$291,937 was recorded, referring to the benefit from a period prior to 2024, under the rules in effect before Law No. 14,789/2023.

This practice aims to meet the needs of the Company's investment plan, previously approved at the Annual General Meeting. For the year ended December 31, 2025, the Company allocated R$2,192,368 to capital increase (Note 1.2.2), ending the year with a balance of R$2,964,772 (R$5,157,140 as of December 31, 2024).

**28 SEGMENT INFORMATION**

**28.1 Criteria for identifying operating segments**

The Board of Directors and Board of Statutory Executive Officers evaluate the performance of the Company's business segments through the Adjusted EBITDA. The Company has revised the segment note to present Adjusted EBITDA as its performance measure.

The operating segments defined by the Company's management are set forth below:

&nbsp;&nbsp;&nbsp;&nbsp;i)Pulp: comprised of the production and sale of hardwood eucalyptus pulp and fluff pulp, mainly to supply the foreign market.

ii)Paper: comprises the production and sale of paper to meet the demands of both the domestic and foreign markets. Consumer goods (tissue) sales are classified under this segment due to their immateriality.

Information related to total assets by reportable segment is not disclosed, as it is not included in the set of information made available to the Company's management, which makes investment decisions and determines the allocation of resources on a consolidated basis.

In addition, with respect to geographical information related to non-current assets, the Company does not disclose such information, as all property, plant and equipment, biological and intangible assets are substantially in Brazil.

**31 EVENTS AFTER THE REPORTING PERIOD**

**31.1 Credit facility arrangement**

On 5 February 2026, the Company completed the arrangement of a new revolving credit facility through its subsidiary Suzano International Finance B.V., replacing the revolving credit facility in place since February 2022 and increasing the total amount available under revolving credit facilities from US$1,275,000 to US$1,775,000 (equivalent to R$9,766,760).
