The Company's assessment has covered five main areas: (i) Personnel: Suzano has local employees and facilities in the city of Rehovot in Israel, through its subsidiary, FuturaGene Israel Ltd. The Company continuously monitors the situation. (ii) Supply Chain: the Company did not identify any short-term or long-term risk of possible interruptions or shortages of materials for its industrial and forestry activities. So far, the only effects observed have been greater volatility in commodities and energy prices. (iii) Logistics: internationally, there was no relevant change in the Company’s logistical operations, with all the routes used remaining substantially unchanged and the moorings in the planned locations being maintained. At the domestic level, no changes in logistical flows were identified. (iv) Commercial: to date, the Company has continued with its transactions as planned, maintaining service to its customers in all its sectors of activity. Sales to a few customers located in Russia were suspended, without any significant financial impact. (v) Continuity of operations: The conflict in Israel may result in disruptions to biotechnology research and development operations at FuturaGene Israel Ltd. As a result of the current scenario, the Company has taken steps to expand its monitoring of the situation, together with its main stakeholders, in order to ensure any updates and information flows required for its global decision-making are available in a timely manner. 1.2.2 Cerrado Project On July 21, 2024, the Cerrado Project started its operation. The plant has a nominal capacity of 2,550,000 tons of eucalyptus pulp production per year. The total investment is R$22,200,000, with substantial payments during the years of 2021 to 2025. 1.2.3 Cancellation of shares and new share buyback program On January 26, 2024, the Board of Directors approved the cancellation of 20,000,000 common shares, with an average cost of R$42.69 per share, in the amount of R$853,725, which were held in treasury, without changing the share capital and against the balances of retained earnings reserves available. Additionally, on August 9, 2024, the Board of Directors approved the cancellation of an additional 40,000,000 common shares, with an average cost of R$51.25 per share, valued at R$2,050,062, which were held in treasury, without changing the share capital and against the balances of available profit reserves. After the cancellation of the shares and the events listed in the note 1.2.4, the share capital of R$19,269,281 is divided into 1,264,117,615 common shares, all nominative, book-entry and with no par value. On the same date, the Company approved a new share buyback program, in which it may acquire up to a maximum of 40,000,000 common shares of its own issue with a maximum period of 18 months, which will end on February 9, 2026. 1.2.4 Share capital increase On April 25, 2024, the Board of Directors approved the increase in the Company's share capital, in the amount of R$10,000,000, without the issuance of new shares, pursuant to article 169, paragraph 1, of the Brazilian Corporation Law, to be paid in through the capitalization of the balance of the Capital Increase Reserve, pursuant to Article 199 of the Brazilian Corporation Law. 1.2.5 Acquisition of equity interest in a specialty fibers business On August 30, 2024, the Company acquired from B & C Alpha Zweite Holding GmbH & Co KG (“B&C”) 5,792,727 shares which represents 15% of the issued share capital of Lenzing Aktiengesellschaft (“Lenzing”), the “Lenzing Transaction”. The Lenzing Transaction was completed after all precedent conditions were fulfilled. The fair value of the cash consideration transferred was EUR 229,971 (equivalent to R$1,436,814), at a price of EUR 39.70 per share. The main terms and conditions of the Lenzing Transaction are: (i) the right of Suzano to hold two out of ten seats on Lenzing’s Supervisory Board; and (ii) Suzano has a right to alter the controlling position by acquiring an additional 15% of the shares held by B&C as part of a mandatory takeover offer to be made by Suzano for all shares of Lenzing under Austrian Takeover Law at a price to be set in accordance with the requirements of the Austrian Takeover Law. Such right can be exercised by Suzano as from the day after the first anniversary of closing until the end of 2028; Management assessed the Lenzing Transaction in accordance with CPC 18 (R3)/ IAS 28 and even though Suzano has two seats on Lenzing’s Supervisory Board, it was concluded that Suzano does not have significant influence over Lenzing since it has no power to participate in decision making, policy making and decisions about dividends or other distributions. Therefore, the investment was recorded at fair value through other comprehensive income (FVOCI), in accordance with CPC 48/IFRS 9 Financial Instruments. 1.2.6 Share purchase agreement - Timber On July 31, 2024, the Company concluded the transaction to purchase 100% of the share capital of the Timber VII SPE S.A. and Timber XX SPE S.A. (the "Timber Transaction"), after completion of all precedent conditions . The fair value of consideration transferred in cash was R$2,143,821. Considering the characteristics of the assets (substantially land and biological assets), the Company elected to apply the optional concentration test to identify a concentration of fair value under paragraph B7A of IFRS 3 and therefore the Timber Transaction was accounted for as an asset acquisition. The impact of this acquisition is reflected in the line-item asset acquisition, net of cash, in the consolidated statement of cash flow. The cash of these companies was R$19,113. On September 30, 2024, these companies were merged to the Company. The merger did not result in a capital increase, given that the Company already held, directly or indirectly, 100% of the share capital of these companies. 1.2.7 Acquisition of Pactiv Evergreen Inc. assets On October 1, 2024, the Company, through its indirect subsidiary Suzano Packaging LLC, acquired the inventories and property, plant and e equipment comprising the integrated coated and uncoated paperboard manufacturing plants, used for the production of Liquid Packaging Board and Cupstock, located in the cities of Pine Bluff – Arkansas and Waynesville – North Carolina, both in the United States of America, previously owned by Pactiv Evergreen Inc. ("Pactiv Transaction"). The "Pactiv Transaction" was finalized after the fulfillment of all precedent conditions. The fair value of the consideration transferred in cash was US$82.932 (equivalent to R$452,153), based on the composition of the assets received. Considering the characteristics of the assets (substantially inventory), the Company elected to apply the optional concentration test to identify a concentration of fair value under paragraph B7A of IFRS 3 and therefore the Pactiv Transaction was accounted for as an asset acquisition. The accounting effects of the transaction were reflected under the inventories line in the consolidated balance sheet. 1.2.8 Interest on own capital On December 4, 2024, the Board of Directors approved the distribution of interest on equity by the Company, in the total gross amount of R$2,500,000, at the rate of BRL 2,017362506 per share, considering the number of “ex-treasury” shares on this date, as remuneration based on the profit shown in the Company's quarterly balance sheet dated September 30, 2024. Interest on equity is subject to 15% withholding tax, except for shareholders who are demonstrably immune or exempt, in accordance with current legislation. This tax, amounting to R$306,327, was withheld and paid in December 2024. 1.2.9 Tax reform consumption On December 20, 2023, Constitutional Amendment (“EC”) No. 132 was enacted, establishing the Tax Reform (“Reform”) on consumption. The Reform model is based on a split VAT (“dual VAT”) with two jurisdictions: a federal one (Contribution on Goods and Services - CBS), which will replace PIS and COFINS, and a subnational one (Tax on Goods and Services - IBS), which will replace ICMS and ISS. A Selective Tax (“IS”) was also created – under federal jurisdiction, which will apply to the production, extraction, commercialization, or importation of goods and services harmful to health and the environment, as defined by a supplementary law. In January 2025, Supplementary Law Bill (“PLP”) 68/24 was sanctioned and converted into Supplementary Law 214/25, which regulated part of the Tax Reform. Although the regulation and establishment of the IBS Management Committee were initially addressed in PLP No. 108/2024, the second regulatory bill of the Reform, which is yet to be reviewed by the Federal Senate, part of the provisions has already been incorporated into PLP No. 68/2024, approved as mentioned above. Among other provisions, it determined the establishment of the Committee by December 31, 2025, which will be responsible for administering the said tax. There will be a transition period between the years 2026 and 2032, in which the two tax systems – old and new – will coexist. The impacts of the Reform on the calculation of the aforementioned taxes, starting from the beginning of the transition period, will only be fully understood once the pending issues are regulated by supplementary law. Consequently, there is no effect of the Reform on the financial statements as of December 31, 2024.

Basis of preparation and presentation of unaudited condensed consolidated financial information [Abstract]
Disclosure of basis of preparation of financial statements [text block]	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 3.2.34. 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: (i) Derivative and non-derivative financial instruments measured at fair value; (ii) Share-based payments and employee benefits measured at fair value; and (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.

Summary of material accounting policies [Abstract]
Summary of significant accounting policies	3 SUMMARY OF MATERIAL ACCOUNTING POLICIES The consolidated financial statements were prepared based on the information of Suzano and its subsidiaries on the same base date, except for subsidiaries Futuragene and Suzano Packaging and associates Biomas, Ensyn, Simplifyber and Spinnova, as well as in accordance with consistent accounting policies and practices. 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, 2024. 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 IFRS 7 – Supplier financing agreements and IAS 7 Statement of cash flow The changes now require the entity to disclose additional information about its supplier financing arrangements that allows users to assess the effects of these arrangements on the entity's liabilities and cash flows and on the entity's exposure to liquidity risk. The disclosures required by the amendments, which would allow understanding of the effects of these agreements on liabilities, cash flows and liquidity include: (a) the terms and conditions of the agreements; (b) at the beginning and end of the reporting period: (i) the carrying values, and the associated items presented in the entity's balance sheet, of the financial liabilities that form part of a supplier financing agreement; (ii) the carrying amounts, and associated items, of the financial liabilities disclosed in accordance with item (i) for which suppliers have already received payment from financiers; and (iii) the range of due dates. (c) the type and effect of non-cash changes in the carrying values of financial liabilities disclosed in accordance with paragraph (b)(i). The Company assessed the content of this pronouncement and did not identify the need to disclose additional information, since (a) the terms and conditions of the agreements have not changed compared to the original conditions; (b) (i) the accounting amounts subject to advance payment are disclosed in Note 17; (ii) the decision to adhere to this transaction is exclusive to the suppliers, and the Company has no influence or management over the amounts received by suppliers from financial institutions; (iii) there was no change in due dates; and (c) there were no non-cash modifications to the supplier advance payment agreements. 3.1.2 Amendments to IFRS 16 – Lease liability in a sale and leaseback transaction The amendments specify that, in measuring the lease liability subsequent to the sale and leaseback, the seller-lessee determines ‘lease payments’ and ‘revised lease payments’ in a way that does not result in the seller-lessee recognising any amount of the gain or loss that relates to the right of use that it retains. The Company assessed the content of this pronouncement and did not identify any impact. 3.1.3 Amendments to IAS 1: Classification of liabilities as current or non-current and non-current liabilities with covenants The changes improve the information provided by the entity when its right to defer the settlement of a liability for at least twelve months is subject to compliance with covenants. The classification of liabilities as current or non-current is based on compliance with covenants that are required on the reporting date or before that date, but never in relation to future events, in addition to requiring disclosure of information in the explanatory notes that allow Users of financial statements assess the risk that the liability may become due within twelve months, including the agreed conditions (for example, their nature and the date by which the entity must comply with them), whether the entity would have complied with the conditions based on its circumstances at the end of the reporting period and how the entity expects to comply with the conditions after the end of the reporting period. The Company assessed the content of this pronouncement and did not identify any impact. 3.1.4 IFRIC agenda decision - disclosure of revenues and expenses for reportable segments (IFRS 8) In July 2024, the IASB approved an IFRIC agenda decision in relation to segment reporting. The decision deals with how an entity applies the requirements in paragraph 23 of IFRS 8 to disclose for each reportable segment specified amounts related to segment profit or loss. The Company assessed the content of this pronouncement and included the cost of the product sold in note 28. 3.2 Accounting policies adopted 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 subsidiaries Futuragene and Suzano Packaging and the affiliates Biomas, Ensyn, 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 CPC 18/IAS 28 and do not have a material effect on the consolidated result and, if any significant event occurred until December 31, 2024, the effect would be adjusted in the consolidated financial statements, as well as consistent accounting policies. On December 31, 2024 , Suzano had an investment in the associate Spinnova, in the amount of R$95,254, representing 18.77% 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. 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. The participation of non-controlling shareholders is highlighted. 3.2.2 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. 3.2.3 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. 3.2.4 Associated and joint ventures 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. 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. 3.2.5 Translation of financial statements into the functional and presentation currency The Company has defined that, for all its wholly owned subsidiaries, the functional and presentation currency is the Brazilian Real, except for subsidiary Suzano Packaging, whose functional currency is the US Dollar, and for investments in associates abroad related to Ensyn Corporation, F&E Technologies LLC and Simplifyber, whose functional currency is the US Dollar, Spinnova and Woodspin, 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. 3.2.5.1 Transactions and balances in foreign currency These are translated using the following criteria: i. Monetary assets and liabilities are translated at the exchange rate in effect at year-end; ii. Non-monetary assets and liabilities are translated at the historical rate of the transaction; iii. Revenue and expenses are translated based on monthly average rate; and iv. The cumulative effects of gains or losses upon translation are recognized in the other comprehensive income. 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. 3.2.6 Hyperinflationary economies Entities based in Argentina, a country considered to have a hyperinflationary economy, are subject to the requirements of IAS 29 - Financial Reporting in Hyperinflationary Economies. Non-monetary items, as well as income and expenses, are adjusted by the changes in the inflation index between the initial recognition and the closing date, so the balances are stated at their current value. However, the Company's wholly-owned subsidiary, based in Argentina, has the Real as its functional currency, and therefore is not considered an entity with a hyperinflationary currency, and does not present its individual financial statements in accordance with IAS 29 - Financial Reporting in Hyperinflationary Economies. The financial statements are presented at historical cost. 3.2.7 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. 3.2.8 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). 3.2.9 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. 3.2.10 Financial instruments 3.2.10.1 Classification Financial instruments are classified based on the purpose for which the financial instruments were acquired, as set forth below: (i) Amortized cost; i. Fair value through other comprehensive income; and i. 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. 3.2.10.1.1 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. Any changes are recognized under financial income (expenses) in the income statement. It includes the balance of cash and cash equivalents, trade accounts receivable, dividends receivable and other assets, classified as financial assets and the balances of suppliers, loans, financing and debentures, lease payables, accounts payable for the acquisition of assets and subsidiaries, , dividends and interest on own capital payable and other liabilities, all of which are classified as financial liabilities. 3.2.10.1.2 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. 3.2.10.1.3 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. This category includes the balance of marketable securities, classified as financial assets financial and derivative financial instruments, including embedded derivatives, stock options, classified as financial assets and liabilities. 3.2.10.2 Impairment of financial assets 3.2.10.2.1 Financial instruments measured at amortized cost 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: i. Significant financial difficulty of the issuer or debtor; ii. Defaults on or late payment of interest or principal under the agreement; 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; iv. It becomes probable that the borrower will enter bankruptcy or other financial reorganization; v. The disappearance of an active market for that financial asset because of financial difficulties; and 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. 3.2.10.2.2 Financial assets at fair value through other comprehensive income The Company periodically evaluates, when measuring fair value, whether there is evidence that a financial asset is impaired. For such financial assets, a significant or prolonged decrease in the fair value of the security below its cost is evidence that the assets are impaired. If any such evidence exists, an impairment loss measured at the difference between the acquisition cost and the current fair value, less any loss previously recognized in other comprehensive income, shall be recognized in the income statement. 3.2.11 Derivative financial instruments and hedging activities Derivative financial instruments are recognized at fair value on the date on which the derivative agreement is entered into and are subsequently remeasured at fair value. Changes in fair value are recorded within the results of derivative financial instruments in the income statement. 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. 3.2.12 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. 3.2.13 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. 3.2.14 Non-current assets held for sale These are measured at their carrying amount or fair value less costs to sell, whichever is lower, and are not depreciated or amortized. Such items are only classified in this account when the sale is highly probable and the assets are available for immediate sale in their current condition. 3.2.15 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. 3.2.16 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. 3.2.17 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: 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; ii. The Company has the right to obtain substantially all the economic benefits from the use of the asset during the contract period; and 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: • It has the right to operate the asset, or • 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: i. In future payments resulting from a change in index or rate; ii. In the estimate of the expected amount to be paid, at the guaranteed residual value; or 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: i. Variable payments that are based on the performance of the leased assets; ii. Guarantees of residual value; and 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. 3.2.18 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. 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 assumptions and judgments, disclosed in Note 16. 3.2.19 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. 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 r

Financial Instruments and Risk Management [Abstract]
Disclosure of financial instruments [text block]	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: (i) Liquidity; (ii) Credit; (iii) Exchange rate; (iv) Interest rate; (v) Fluctuations of pulp selling and commodity prices; and (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: (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; (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 (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: (i) Protection of cash flow against currency mismatches; (ii) Protection of revenue flows for debt settlement and interest payments against fluctuations in interest rates and currencies; and (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: (i) Does not enter into leveraged transactions or other forms of embedded options that change the purpose of protection (hedge); (ii) Does not have double-indexed debt or other forms of implied options; and (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. 4.1.2 Classification All transactions with financial instruments are recognized for accounting purposes and classified in the following categories: Note 12/31/2024 12/31/2023 Assets Amortized cost Cash and cash equivalents 5 9,018,818 8,345,871 Marketable securities 6 Trade accounts receivable 7 9,132,860 6,848,454 Other assets (1) 628,275 737,222 18,779,953 15,931,547 Fair value through other comprehensive income Investments 14.1 1,138,066 23,606 1,138,066 23,606 Fair value through profit or loss Derivative financial instruments 4.5.1 3,887,100 4,430,454 Marketable securities 6 13,363,511 13,267,286 17,250,611 17,697,740 37,168,630 33,652,893 Liabilities Amortized cost Trade accounts payable 17 6,033,285 5,572,219 Loans, financing and debentures 18.1 101,435,531 77,172,692 Lease liabilities 19.2 6,972,915 6,243,782 Liabilities for assets acquisitions and subsidiaries 23 120,490 187,187 Dividends and interests on own capital payable 2,200,917 1,316,528 Other liabilities (1) 143,330 116,716 116,906,468 90,609,124 Fair value through profit or loss Derivative financial instruments 4.5.1 10,454,820 2,436,072 10,454,820 2,436,072 127,361,288 93,045,196 90,192,658 59,392,303 (1) Does not include items not classified as financial instruments. 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: Yield used to discount/methodology 12/31/2024 12/31/2023 Quoted in the secondary market In foreign currency Bonds Secondary Market 48,734,909 38,703,379 Estimated present value In foreign currency Export credits (“Prepayment”) SOFR 22,740,891 17,783,760 Assets Financing SOFR 422,115 278,107 ECA - Export Credit Agency SOFR 864,202 IFC - International Finance Corporation SOFR 6,261,715 3,198,761 Panda Bonds - CNH Fixed 951,125 In local currency BNDES – TJLP DI 1 171,109 215,458 BNDES – TLP DI 1 3,275,012 2,712,762 BNDES – Fixed DI 1 3,903 BNDES – TR DI 1 33,466 BNDES – Selic (“Special Settlement and Custody System”) DI 1 645,139 686,798 BNDES – UMBNDES DI 2 106,966 Assets Financing DI 1 60,566 75,622 Debentures DI 1/IPCA 12,002,992 8,881,277 NCE (“Export Credit Notes”) DI 1 108,308 110,396 NCR (“Rural Credit Notes”) DI 1 2,424,457 2,228,806 Export credits (“Prepayment”) DI 1 824,035 98,802,972 75,703,064 The book values of loans and financing are disclosed in Note 18. 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, 2024, 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. 12/31/2024 Book value Undiscounted cash flow Up to 1 year 1 - 2 years 2 - 5 years More than 5 years Liabilities Trade accounts payables 6,033,285 6,033,285 6,033,285 Loans, financing and debentures 101,435,531 142,028,543 13,599,011 14,235,170 50,858,667 63,335,695 Lease liabilities 6,972,915 12,099,294 1,302,590 1,176,832 3,094,493 6,525,379 Liabilities for asset acquisitions and subsidiaries 120,490 146,082 23,425 22,400 100,257 Derivative financial instruments 10,454,820 13,878,150 1,676,180 957,540 1,489,357 9,755,073 Dividends and interests on own capital payable 2,200,917 2,200,917 2,200,917 Other liabilities 143,330 143,330 60,892 82,438 127,361,288 176,529,601 24,896,300 16,474,380 55,542,774 79,616,147 12/31/2023 Book Undiscounted cash flow Up to 1 year 1 - 2 years 2 - 5 years More than 5 years Liabilities Trade accounts payables 5,572,219 5,572,219 5,572,219 Loans, financing and debentures 77,172,692 105,526,852 7,648,237 12,983,542 31,355,362 53,539,711 Lease liabilities 6,243,782 11,021,519 1,172,568 1,045,795 2,743,793 6,059,363 Liabilities for asset acquisitions and subsidiaries 187,187 215,891 94,948 18,314 87,520 15,109 Derivative financial instruments 2,436,072 2,801,258 66,433 1,278,953 1,191,014 264,858 Dividends and interests on own capital payable 1,316,528 1,316,528 1,316,528 Other liabilities 116,716 116,716 58,955 57,761 93,045,196 126,570,983 15,929,888 15,384,365 35,377,689 59,879,041 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 12/31/2024 12/31/2023 Low (1) 8,899,516 6,549,975 Average (2) 174,048 156,883 High (3) 89,596 173,558 9,163,160 6,880,416 1) Current and overdue up to 30 days. 2) Overdue between 30 and 90 days. 3) Overdue more than 90 days. A portion of the amounts above does not consider the expected credit losses calculated based on the provision matrix of R$30,300 and R$31,962 as of December 31, 2024 and 2023, 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 by the main risk rating agencies.

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: (i) Protecting cash flow due to currency mismatch; (ii) Mitigating exposure to interest rates; (iii) Reducing the impacts of fluctuations in commodity’s prices; and (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 Company's Board of Directors approved the contracting of extraordinary hedge, in addition to the strategy mentioned above, for investments in the Cerrado Project, with a term of up to 36 months as of November 2021, in an amount of up to US$1,000,000. On July 27, 2022, the Board of Directors approved the expansion of the program, increasing the maximum amount (notional) to US$1,500,000, maintaining the previously established deadline. In order to provide transparency on the hedge program for the Cerrado Project, since December 31, 2021 the Company has started to prominently disclose the respective contracted operations. The assets and liabilities that are exposed to foreign currency, substantially in US$, are set forth below: 12/31/2024 12/31/2023 Assets Cash and cash equivalents 6,496,039 6,432,557 Marketable securities 70,255 7,378,277 Trade accounts receivable 7,090,160 5,049,609 Derivative financial instruments 3,887,100 3,070,594 17,543,554 21,931,037 Liabilities Trade accounts payable (1,350,763) (1,625,011) Loans and financing (83,004,915) (61,304,673) Liabilities for asset acquisitions and subsidiaries (93,308) (127,598) Derivative financial instruments (10,448,379) (1,867,882) (94,897,365) (64,925,164) (77,353,811) (42,994,127) 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$6.1923). This analysis assumes that all other variables, particularly interest rates, remain constant. The other scenarios considered the depreciation of the Brazilian Real against the US$ at the rates of 25% and 50% before taxes. The following table set forth the potential impacts at their absolute amounts: 12/31/2024 Effect on profit or loss Probable (base value) Possible (25%) Remote (50%) Cash and cash equivalents 6,496,039 1,624,010 3,248,020 Marketable securities 70,255 17,564 35,128 Trade accounts receivable 7,090,160 1,772,540 3,545,080 Trade accounts payable (1,350,763) (337,691) (675,382) Loans and financing (83,004,915) (20,751,229) (41,502,458) Liabilities for asset acquisitions and subsidiaries (93,308) (23,327) (46,654) 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 scenarios considered the depreciation of the Brazilian Real against the US$ by 25% and 50%, before taxes, based on the base scenario on December 31, 2024. The following table set out the possible impacts assuming these scenarios: 12/31/2024 Effect on profit or loss Probable (base value) Possible 25% Remote 50% Dollar/Real Derivative financial instruments Derivative options (4,328,970) (9,226,995) (19,121,860) Derivative swaps (1,843,087) (2,604,422) (4,992,835) Derivative Non-Deliverable Forward (‘NDF’) Contracts (331,876) (896,742) (1,788,477) Embedded derivatives (80,759) (183,663) (367,326) Commodity Derivatives 16,973 4,236 8,478 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: 12/31/2024 Effect on profit or loss Probable Possible (25%) Remote (50%) CDI/SELIC Cash and cash equivalents 2,422,308 73,578 147,155 Marketable securities 13,293,256 403,783 807,565 Loans and financing 9,290,595 282,202 564,404 TJLP/TLP Loans and financing 202,961 3,770 7,540 SOFR Loans and financing 28,534,005 320,294 640,588 4.4.2.2 Sensitivity analysis – exposure to interest rates – derivative financial instruments This analysis assumes that all other variables remain constant. The other scenarios considered a depreciation of 25% and 50% in market interest rates. The following table sets out the possible impacts of these assumed scenarios: 12/31/2024 Effect on profit or loss Probable Probable 25% Remote 50% CDI Derivative financial instruments Liabilities Derivative options (4,328,970) (943,363) (1,868,091) Derivative swaps (1,843,087) (91,012) (178,459) SOFR Derivative financial instruments Liabilities Derivative swaps (1,843,087) (136,036) (261,559) 4.4.2.3 Sensitivity analysis to changes in the consumer price indices of the US economy For the measurement of the probable scenario, the United States Consumer Price Index (“US-CPI”) was considered on December 31, 2024. The probable scenario was extrapolated considering a depreciation of 25% and 50% in the US-CPI to define the possible and remote scenarios, respectively. The following table sets out the possible impacts, assuming these scenarios in absolute amounts: 12/31/2024 Effect on profit or loss Probable (base value) Possible (25%) Remote (50%) Embedded derivative in a commitment to purchase standing wood, originating from a forest partnership agreement (80,759) (32,607) (66,859) 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 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: (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. (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. (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. (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. (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, 2024 are as set forth below: Interest rate curves Term Brazil (1) United States of America (2) US Dollar coupon (1) 1M 12.15% p.a 4.33% p.a 8.46% p.a 6M 14.19% p.a 4.25% p.a 6.37% p.a 1Y 15.41% p.a 4.17% pa. 6.41% p.a 2Y 15.94% p.a 4.16% p.a 6.29% p.a 3Y 15.89% p.a 4.21% pa. 6.22% p.a 5Y 15.60% p.a 4.36% p.a 6.41% p.a 10Y 14.96% p.a 4.88% p.a 7.31% p.a 1) Source: B3 2) Source: Bloomberg 4.5.1 Outstanding derivatives by contract type, including embedded derivatives The positions of outstanding derivatives are set forth below: Notional value, net in U.S.$ Fair value in R$ 12/31/2024 12/31/2023 12/31/2024 12/31/2023 Instruments as part of cash flow protection strategy Cash flow hedge Zero Cost Collar 6,852,200 4,500,200 (4,328,970) 1,968,337 NDF (R$ x US$) 581,000 505,000 (331,876) 162,776 NDF (€ x US$) 262,088 100,362 Debt hedges Swap SOFR to Fixed (US$) 1,973,705 2,555,626 394,129 741,492 Swap IPCA to CDI (notional in Brazilian Reais) 8,128,395 4,274,397 (825,899) 47,645 Swap CNH to Fixed (US$) 165,815 (6,440) Swap CDI x Fixed (US$) 909,612 1,025,000 (776,261) (1,081,964) Pre-fixed Swap R$ to US$ (US$) 200,000 (203,045) Swap CDI x SOFR (US$) 610,171 125,000 (590,764) 25,774 Swap SOFR to SOFR (US$) 150,961 150,961 (37,850) (16,615) Commodity Hedge Swap US$ e US-CPI (1) 138,439 131,510 (80,759) 230,471 Zero Cost Collar (Brent) 163,941 163,100 6,097 (3,148) Swap VLSFO/Brent 39,706 142,794 10,873 22,297 (6,567,720) 1,994,382 Current assets 1,006,427 2,676,526 Non-current assets 2,880,673 1,753,928 Current liabilities (2,760,273) (578,763) Non-current liabilities (7,694,547) (1,857,309) (6,567,720) 1,994,382 (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: (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. (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. (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. (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. (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. (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. (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$. (viii) Zero Cost Collar: positions in an instrument that consists of the simultaneous combination of a purchase of put options and the sale of call options in US$, 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. (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. (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. (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. (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. (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, 2024 compared to the fair values measured on December 31, 2023 are explained substantially by the depreciation 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 h

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, 2024, was R$6,821,539 (R$4,273,623 as of December 31, 2023). 7.2 Breakdown of trade accounts receivable by maturity 12/31/2024 12/31/2023 Current 8,216,570 5,904,402 Overdue Up to 30 days 682,142 644,644 From 31 to 60 days 134,674 57,395 From 61 to 90 days 38,187 97,639 From 91 to 120 days 17,701 40,533 From 121 to 180 days 12,402 34,708 From 181 days 31,184 69,133 9,132,860 6,848,454 7.3 Roll-forward of expected credit losses 12/31/2024 12/31/2023 Opening balance (31,962) (21,109) (Provisions)/Reversals, net (2,585) (35,202) Write-offs 5,790 24,230 Exchange rate variations (1,543) 119 Closing balance (30,300) (31,962) The Company maintains guarantees for overdue receivables as part of its commercial operations, through credit insurance policies, letters of credit and other guarantees.

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.

Disclosure of temporary difference, unused tax losses and unused tax credits [abstract]
Disclosure of income tax [text block]	12 INCOME AND SOCIAL CONTRIBUTION TAXES The Company calculates income tax and social contribution taxes, current and deferred, based on the following rates: (i) 15% plus an additional 10% on taxable income in excess of R$240 for IRPJ; and (ii) 9% for CSLL, on the net income. Balances are recognized in the Company's income on an accrual basis. 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. Deferred income and social contribution taxes are recognized at the net amounts in non-current assets or liabilities. In Brazil, Law nº. 12,973/14 revoked article 74 of Provisional Measure nº. 2,158/01 and determines that 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, must be added in the determination of taxable income and the social contribution calculation basis of the controlling entity domiciled in Brazil, at each year ended. 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, 2024. There is no provision for tax related to the non-double taxation profits of such subsidiary in 2024. Disclosures about uncertain tax positions for income tax and social contribution (IFRIC 23) are presented in Note 20.2. 12.1 Deferred taxes 12.1.1 Deferred income and social contribution taxes 12/31/2024 12/31/2023 Tax loss 796,831 1,209,968 Negative tax basis of social contribution 307,143 457,030 Assets - temporary differences Provision for judicial liabilities 324,873 324,158 Operating provisions and other losses 1,308,352 1,214,807 Exchange rate variations 7,385,034 2,384,153 Derivatives losses (“MtM”) (2) 2,230,835 Amortization of fair value adjustments arising from business combinations 625,745 654,358 Unrealized profit on inventories 539,157 151,578 Leases (2) 606,944 356,110 14,124,914 6,752,162 Liabilities - temporary differences Goodwill - tax benefit on unamortized goodwill 1,589,887 1,301,654 Property, plant and equipment - deemed cost 1,066,883 1,137,483 Depreciation for tax-incentive reason (1) 733,640 799,857 Capitalized loan costs 947,482 640,063 Fair value of biological assets 1,317,095 1,115,432 Deferred taxes, net of fair value adjustments 342,141 370,947 Tax credits - gains from tax lawsuit (exclusion of ICMS from the PIS and COFINS basis) 137,928 150,691 Derivatives gains (“MtM”) (2) 678,090 Other temporary differences 18,439 24,109 6,153,495 6,218,326 Non-current assets 7,984,015 545,213 Non-current liabilities 12,596 11,377 (1) Tax depreciation is taken as a benefit only in the income tax calculation bases. (2) The Company presents a net balance of derivatives and leases, as gains and losses from deferred taxes are offset simultaneously. For the derivatives line, the passive temporary difference was R$1,321,614 and asset temporary difference of R$3,552,449 (passive temporary difference of R$1,506,354 and asset temporary difference of R$828,264 as of December 31, 2023). For the lease line, the passive temporary difference was R$1,763,847 and asset temporary difference was R$2,370,791 (passive temporary difference of R$1,766,776 and asset temporary difference of R$2,122,886 as of December 31, 2023). 12.1.2 Breakdown of accumulated tax losses and social contribution tax losses carried forward 12/31/2024 12/31/2023 Tax loss carried forward 3,187,324 4,839,872 Negative tax basis of social contribution carried forward 3,412,700 5,078,111 12.1.3 Roll-forward of deferred tax assets 12/31/2024 12/31/2023 Opening balance 533,836 3,985,297 Tax loss (413,137) 2,872 Negative tax basis of social contribution (149,887) 11,780 Provision for judicial liabilities 715 55,562 Operating provisions and other losses 93,545 215,779 Exchange rate variation 5,000,881 (1,913,350) Derivative (gains) losses (“MtM”) 2,908,925 (668,926) Amortization of fair value adjustments arising from business combinations 193 2,219 Unrealized profit on inventories 387,579 (211,474) Leases 250,834 (8,728) Goodwill - tax benefit on unamortized goodwill (288,233) (278,551) Property, plant and equipment - deemed cost 70,600 79,866 Depreciation accelerated for tax-incentive reason 66,217 70,140 Capitalized loan costs (307,419) (429,229) Fair value of biological assets (201,663) (412,158) Credits on exclusion of ICMS from the PIS/COFINS tax base 12,763 43,430 Other temporary differences 5,670 (10,693) Closing balance 7,971,419 533,836 12.2 Reconciliation of the effects of income tax and social contribution on profit or loss 12/31/2024 12/31/2023 12/31/2022 Net income (loss) before taxes (13,111,053) 17,997,216 28,655,581 Income tax and social contribution benefit (expense) at statutory nominal rate of 34% 4,457,758 (6,119,053) (9,742,898) Tax effect on permanent differences Taxation (difference) on profit of associates in Brazil and abroad (1) 484,717 1,688,656 4,915,243 Equity method (4,707) (6,589) 96,685 Thin capitalization (2) (46,796) (505,553) Interest on own capital 850,000 510,000 — Credit related to Reintegra Program 11,896 7,176 7,829 Director bonuses (9,587) (4,907) (12,208) Tax incentives (Note 12.3) (3) 336,541 128,650 51,839 Donations/Fines – Other (60,271) (47,972) (71,631) 6,066,347 (3,890,835) (5,260,694) Income tax Current (999,421) (352,577) (464,312) Deferred 5,482,647 (2,561,991) (3,485,267) 4,483,226 (2,914,568) (3,949,579) Social Contribution Current (366,178) (42,815) (46,584) Deferred 1,949,299 (933,452) (1,264,531) 1,583,121 (976,267) (1,311,115) Income and social contribution benefits (expenses) on the year 6,066,347 (3,890,835) (5,260,694) (1) The difference in the taxation of subsidiaries is substantially due to the differences between the nominal tax rates in Brazil and those of subsidiaries located abroad. (2) The Brazilian thin capitalization rules establish that interest paid or credited by a Brazilian entity to a related party abroad may only be deducted for income tax and social contribution purposes if the interest expense is viewed as necessary for the activities of the local entity, and when certain limits and requirements are met. On December 31, 2024, all limits and requirements were met, and on December 31, 2023 and 2022, the Company did not meet all of the limits and requirements, and therefore the expense is not deductible for the period. (3) Income tax and social contribution deduction on profit or loss referring to the use of tax incentives: (i) exploitation profits, (ii) expenses with research and development, (iii) PAT benefits ("Worker Food Program"), (iv) donations made in cultural projects, (v) children and adolescents rights funds, (vi) sports incentives, (vii) funds for the elderly and (viii) extensions to maternity and paternity leave. 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. Area/Regions Company Maturity Northeast Development Superintendence (“SUDENE”) Aracruz (ES) Portocel 2030 Aracruz (ES) Suzano 2031 Imperatriz (MA) Suzano 2032 Mucuri (BA) Suzano 2032 São Luís (MA) Itacel 2033 Eunápolis (BA) Veracel 2033 Superintendence of Amazon Development (“SUDAM”) Belém (PA) Suzano 2025 On June 13, 2024, the tax incentive for exploitation profits was approved for the company Terminal de Celulose de Itaqui S/A and on July 22, 2024, the tax incentive request was renewed for the company Veracel Celulose S/A in areas under the jurisdiction of the SUDENE, granting a 75% reduction in Corporate Income Tax (IRPJ), with a validity of 10 years for utilizing this tax benefit. These incentives aim to promote regional development by encouraging investments in strategic areas. 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. From 2024, the Company is subject to the OECD Pillar Two model rules in certain European jurisdictions where it operates, with Austria standing out as a relevant operation. To date, there has been no material impact on the financial statements due to this topic. In December 2024, Law 15.079/2024 was published, establishing the Additional Social Contribution on Net Income (CSLL) in the process of adapting Brazilian legislation to the GloBE rules, whose application comes into effect as of January 1, 2025. The main impact is the need to adapt compliance structures and the calculation of any additional CSLL (Top-up Tax). The Company reaffirms its commitment to tax compliance and is already taking the necessary actions to ensure the proper implementation of the new rule in Brazil, in line with global best practices and current legislation. The Company also continually assesses legislative developments in the jurisdictions in which it operates in order to map potential effects on its operations.

Disclosure of detailed information about biological assets [text block]	13 BIOLOGICAL ASSETS The roll-forward of biological assets is as set forth below: 12/31/2024 12/31/2023 Opening balance 18,278,582 14,632,186 Additions 7,180,450 5,777,952 Additions of merged companies (1) 366,785 Depletions (4,831,916) (3,680,997) Transfers 102,790 (136,297) Gain on fair value adjustments 1,431,530 1,989,831 Disposals (130,922) (128,370) Write-offs (114,298) (175,723) Closing balance 22,283,001 18,278,582 (1) Refers to the acquisition and merger of 100% of the share capital of the companies Timber VII and Timber XX (note 1.2.6). 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: (i) Average cycle of forest formation between 6 and 7 years; (ii) Effective area of forest from the 3rd year of planting; (iii) The IMA consists of the estimated volume of production of wood with bark in m3 per hectare, ascertained based on the genetic material used in each region, silvicultural practices and forest management, production potential, climate factors and soil conditions; (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; (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 (vi) The discount rate corresponds to the Weighted Average Cost of Capital (“WACC”). The table below discloses the measurement of the premises adopted: 12/31/2024 12/31/2023 Useful productive planted area (hectare) 1,243,191 1,094,611 Mature assets (6 to 7 years) 191,737 144,942 Immature assets (1 to 5 years) 1,051,454 949,669 Average annual growth (IMA) – m 3 /hectare/year 37.62 37.92 Average gross sale price of eucalyptus – R$/m 3 101.38 96.04 Discount rate (post-tax) 8.80 % 8.80 % The pricing model considers the net cash flows, after the deduction of taxes on profit at the applicable rates. The fair value adjustment justified by the combined variations of the indicators mentioned above resulted in a positive variation of R$1,431,530 recognized in other operating income (expenses), net (Note 29). 12/31/2024 12/31/2023 Physical changes and discount rate (1) 609,259 1,575,017 Price 822,271 414,814 1,431,530 1,989,831 1) Includes the variation of indicators: IMA, discount rate and area. The Company manages the financial and climate risks related to its agricultural activities in a preventive manner. To reduce the risks arising from edaphoclimatic factors, the weather is monitored through meteorological stations and, in the event of pests and diseases, our Department of Forestry Research and Development, an area specialized in physiological and phytosanitary aspects, has procedures to diagnose and act rapidly against any occurrences and losses (Note 4.8). The Company has no biological assets pledged as collateral on December 31, 2024 and 2023.

Disclosure of intangible assets and goodwill [text block]	16 INTANGIBLE 16.1 Goodwill and intangible assets with indefinite useful lives 12/31/2024 12/31/2023 Goodwill - Facepa 119,332 119,332 Goodwill - Fibria 7,897,051 7,897,051 Goodwill - MMC Brasil (1) 170,859 170,859 Other (2) 5,097 4,834 8,192,339 8,192,076 (1) Refers to the goodwill of the MMC Brasil business combination. (2) 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 2024 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 3.6% 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 8.91% 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$/t) 684.9 Net average pulp price – Internal market (US$/t) 735.5 Average exchange rate (R$/US$) 5.40 Discount rate (pos-tax) 8.91% p.a. Discount rate (pre-tax) 12.50% p.a. For the year ended December 31, 2024, the Company did not identify the need to record any impairment provision for intangible assets. 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 (9.91% instead of 8.91%), the Company would still not need to record an impairment provision. The Company have considered and assessed possible changes for other key assumptions and have not identified any instances that could cause the carrying amount of the cash generating units to exceed its recoverable amount. For the paper cash-generating unit (“CGU”), the asset recoverability test is carried out annually based on the EV/EBITDA multiple method. For the year ended December 31, 2024, the Company did not identify the need to record any impairment provision for intangible assets. 16.2 Intangible assets with limited useful lives 12/31/2024 12/31/2023 Opening balance 6,557,009 7,173,183 Additions 161,779 104,931 Fair value adjustment MMC Brasil 189,655 Write-offs (2) Amortization (1,008,824) (990,432) Transfers and others 79,674 Closing balance 5,709,964 6,557,009 Represented by Average rate % Non-competition agreements 5.00 4,508 4,818 Port concessions 3.94 632,253 537,179 Lease agreements 16.90 6,875 Supplier agreements 12.66 25,925 40,739 Port service contracts 4.23 520,459 549,821 Cultivars 14.28 20,391 40,784 Trademarks and patents 8.35 170,306 188,723 Customer portfolio 9.09 4,104,900 4,925,879 Supplier agreements 17.64 295 10,861 Software 20.80 201,476 141,178 Other 10.00 29,451 110,152 5,709,964 6,557,009 Cost 12,540,497 12,378,761 Amortization (6,830,533) (5,821,752) Closing balance 5,709,964 6,557,009

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.

For the year ended December 31, 2024, the estimated amount of the possible exposure is R$1,688,690 (R$1,630,537 as of December 31, 2023).

For the year ended December 31, 2024, the total amount of the possible exposure is R$920,628 (R$845,164 as of December 31, 2023). (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.

For the year ended December 31, 2024 the total amount of the possible exposure is R$875,466 (R$827,186 as of December 31, 2023).

In addition to the Company, the statutory executive officers of Suzano Trading were also included as co-defendants. 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, through Resolution No.104000033, the judgment was converted into a diligence. Currently awaiting the conclusion of the due diligence. In the year ended December 31, 2024 the total amount of the possible exposure is R$609,548 (R$563,723 as of December 31, 2023).

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”).

Currently, the partial settlement of the ruling is being discussed, and the special appeal is awaiting judgment by the CSRF. For the year ended December 31, 2024 the total amount of the possible exposure is R$201,199 (R$190,875 as of December 31, 2023). (vi) Tax Assessment - Taxation on a universal basis – Period of 2015: On November 3, 2020, the Company was notified of a Tax Assessment issued by the RFB under the accusation that it had failed to pay IRPJ and CSLL for the 2015 calendar year. The infraction was based on the lack of addition, in determining the real profit and the CSLL calculation base, of the profits earned by its foreign subsidiaries. Based on the legal advisors hired to present the defense, the Company classified the risk of loss as possible. The Company filed an administrative defense, which was partially upheld in the first instance. Following this decision, the Company filed a voluntary appeal on June 8, 2024, which was partially upheld on May 14, 2024, resulting in the cancellation of the majority of the tax assessment. For the remaining portion, the Company filed a special appeal, which is currently awaiting judgment. For the year ended December 31, 2024 the total amount of exposure is R$4,712 (R$176,917 as of December 31, 2023). (vii) 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. For the year ended December 31, 2024 the total amount of the possible exposure is R$150,869 (R$143,912 as of December 31, 2023).

For the year ended December 31, 2024, there is no estimated amount of exposure due to the favorable outcome (R$102,496 as of December 31, 2023). (xii) 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. For the year ended December 31, 2024, the estimated amount of exposure is R$101,654. 20.2.2 Labor On December 31, 2024, the Company was a defendant in 1,135 labor lawsuits, totaling R$171,480 (1,034 labor lawsuits, totaling R$194,883 as of December 31, 2023). 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, 2024, the Company was a defendant in approximately 201 civil, environmental and real estate lawsuits, totaling R$5,065,714 (219 lawsuits totaling R$4,462,964 as of December 31, 2023). 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: (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. At the moment, the União Comércio and CNT have filed motions for clarification to highlight various gaps and omissions identified in the judgment. (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.

Disclosure of share-based payment arrangements [text block]	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 (“PS”) The number of phantom shares to be granted to each beneficiary is calculated based on a fixed 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. Since phantom stock option plans are settled in cash, their fair values are measured at the end of each reporting period. If the beneficiaries leave the Company during the vesting period, they lose the right to exercise the phantom shares. The plan transactions are presented below: Number of shares Year of grant Fair value on grant date 31/12/2023 Granted during of the year Cancelled Exercised (1) 31/12/2024 Available for completion Restricted year for transfer of shares 2025 2026 2027 2028 2019 R$42.81 39,461 903 (40,364) 2020 R$38.36 984,160 22,525 (204,963) (768,338) 33,384 33,384 2021 R$62.15 1,724,020 39,387 (66,231) (822,696) 874,480 425,280 449,200 2022 R$57.54 3,686,722 84,207 (286,478) (23,014) 3,461,437 3,113,607 324,611 23,219 2023 R$48.79 3,294,062 74,647 (283,548) (32,982) 3,052,179 28,333 2,721,535 302,311 2024 R$56.52 2,759,878 (81,947) (2,914) 2,675,017 2,893 2,467,693 204,431 Number of stock options 9,728,425 2,981,547 (923,167) (1,690,308) 10,096,497 458,664 3,591,140 3,049,039 2,793,223 204,431 Book value 268,489 173,486 (80,001) 361,974 Book value of the previous year 162,117 154,318 (47,946) 268,489 (1) The average price of the share options exercised and exercised due to termination of employment on December 31, 2024 was R$42.36 (forty-two reais and thirty-six cents) (R$58.07 (fifty-eight reais and seven cents) as at December 31, 2023). 22.2 Restricted shares plan (“Performance Shares”) 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.

On April 25, 2024, the Board of Directors approved an increase in the Company's share capital in the amount of R$10,000,000, as described in note 1.2.4. 24.2 Dividends and reserve calculations The Company´s bylaws establishes that the minimum annual dividend shall be the lower of: (i) 25% of the adjusted net income for the year pursuant to Article 202 of Brazilian Law No. 6,404/76; or (ii) 10% of the Company's consolidated operating cash generation (“GCO”) for the year. In the year ended December 31, 2024, no dividends were distributed as a result of the loss for the year. On December 4, 2024, the Board of Directors approved the payment of interest on equity by the Company, in the total gross amount of R$2,500,000, as described in note 1.2.8. In the year ended December 31, 2023, based on the criteria defined in the bylaws, mandatory minimum dividends were determined in accordance with item (ii) above, as set forth below: 12/31/2023 Accounting EBITDA 19,537,398 Adjustments to EBITDA (1,264,428) Adjusted EBTIDA 18,272,970 Capex Maintenance (Sustain) (6,706,367) GCO = Adjusted EBTIDA - Capex Maintenance 11,566,603 Dividends (10%) - Art. 26, "c" of the Bylaws 1,156,660 Interest on own capital distributed and dividends 1,500,000 Withholding income tax (190,119) Interest on own capital distributed in excess (1) (153,221) (1) Considering that the distribution of Interest on own capital in the year ending in 2023 exceeded the minimum mandatory dividends, the Company does not expect to propose additional dividends at the next shareholders' meeting. 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: (i) Legal: measured based on 5% (five percent) of the net profit of each fiscal year as specified in Article 193 of Brazilian Law No. 6,404/76, which shall not exceed 20% of the share capital, whereas in the year in which the balance of the legal reserve plus the capital reserve amounts exceeds 30% (thirty percent) of the share capital, the allocation of part of the profit will not be mandatory. The use of this reserve is restricted to loss compensation and capital increases, and aims to ensure the integrity of the share capital. For the year ended December 31, 2024, the balance of this reserve is R$1,847,109 (R$1,847,109 as of December 31, 2023). (ii) Capital increase: measured on the basis of up to 90% (ninety percent) of the remaining balance of the 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 minimum mandatory dividends. The constitution of this reserve aims to ensure the Company has adequate operating conditions. For the year ended December 31, 2024, the balance of this reserve is R$2,807,632 (R$15,670,952 as of December 31, 2023). (iii) Special statutory: measured on the basis of up to 10% (ten percent) of the remaining balance of net income for the year, and aims to ensure the continuity of the distribution of dividends, up to the limit of 20% of the share capital. For the year ended December 31, 2024, the balance of this reserve is R$1,847,109 (R$1,887,576 as of December 31, 2023). (iv) Tax incentives: set up under the terms of article 195-A of Law 6,404/76, amended by Law 11,638/07 and at the proposal of the management bodies, the company will allocate the portion of net income arising from donations or government subsidies to investments, this portion being excluded from the basis for calculating the mandatory dividend. For the year ended December 31, 2024, the balance of this reserve is R$1,319,908 (R$998,237 as of December 31, 2023). This increase can be explained by the reserve relating to the benefits of Operating Profit (note 12.3) and Reinvestment. The Operating Profit, applicable to the plants in the states of Espírito Santo, Maranhão and Bahia (under Sudene's approval), in addition to the plant in Belém do Pará (under Sudam's approval), contributed to a reserve of R$299,515 in the year ended December 31, 2024. With regard to the Reinvestment incentive, used only for the Aracruz (ES), Mucuri (BA) and Imperatriz (MA) units, which are located in the region administered by Sudene, the use of the benefit resulted in an increase of R$14,574 to the reserve for the year. With regard to the investment subsidy tax incentive, in accordance with Law 14.789/2023, the Company taxed the results equivalent to these amounts, and there was no creation of a reserve for this tax incentive for the current year, only the creation of R$7,582, referring to the benefit of the previous year, under the rules prior to Law 14.789/2023. (v) Investment reserve: constituted in accordance with article 196 of Law No. 6,404/76, modified by Law No. 11,638/07, profit retention is carried out based on a capital budget. This practice aims to meet the needs of the Company's investment plan, previously approved at the Ordinary General Meeting. In the year ended December 31, 2024, the Company absorbed the loss for the year in the amount of R$(7,315,184), ending the year ended 2024 with a balance of R$5,157,140 (R$14,972,324 as of at December 31, 2023). 24.4 Other reserves These are changes that occur in shareholders' equity arising from transactions and other events that do not originate with shareholders and are disclosed net of tax effects, as set forth below: Debenture conversion 5th issue Actuarial loss Exchange variation and fair value of financial assets Exchange variation on conversion of financial statements of foreign subsidiaries Deemed cost Total Balances at December 31, 2022 (45,746) (144,799) 2,163 3,218 1,904,680 1,719,516 Actuarial loss (84,828) (84,828) Loss on conversion of financial assets and fair value (865) (865) Gain on conversion of financial statements and on foreign investments 5,178 5,178 Partial realization of deemed cost, net of taxes (100,705) (100,705) Balances at December 31, 2023 (45,746) (229,627) 1,298 8,396 1,803,975 1,538,296 Actuarial loss 90,931 90,931 Loss on conversion of financial assets and fair value (364,231) (364,231) Gain on conversion of financial statements and on foreign investments 163,185 163,185 Partial realization of deemed cost, net of taxes (79,385) (79,385) Balances at December 31, 2024 (45,746) (138,696) (362,933) 171,580 1,724,590 1,348,796 24.5 Treasury shares On December 31, 2024, the Company had 24,875,787 (34,765,600 as of December 31, 2023) of its own common shares held in treasury, with an average cost of R$53.84 per share, with a historical value of R$1,339,197 (R$1,484,014 as at December 31, 2023) and the market corresponding to R$1,536,826 (R$1,934,010 as at December 31, 2023).

Disclosure of entity's operating segments [text block]	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: 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.

Summary of material accounting policies [Abstract]
New Accounting Pronouncements, Policy	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 IFRS 7 – Supplier financing agreements and IAS 7 Statement of cash flow The changes now require the entity to disclose additional information about its supplier financing arrangements that allows users to assess the effects of these arrangements on the entity's liabilities and cash flows and on the entity's exposure to liquidity risk. The disclosures required by the amendments, which would allow understanding of the effects of these agreements on liabilities, cash flows and liquidity include: (a) the terms and conditions of the agreements; (b) at the beginning and end of the reporting period: (i) the carrying values, and the associated items presented in the entity's balance sheet, of the financial liabilities that form part of a supplier financing agreement; (ii) the carrying amounts, and associated items, of the financial liabilities disclosed in accordance with item (i) for which suppliers have already received payment from financiers; and (iii) the range of due dates. (c) the type and effect of non-cash changes in the carrying values of financial liabilities disclosed in accordance with paragraph (b)(i). The Company assessed the content of this pronouncement and did not identify the need to disclose additional information, since (a) the terms and conditions of the agreements have not changed compared to the original conditions; (b) (i) the accounting amounts subject to advance payment are disclosed in Note 17; (ii) the decision to adhere to this transaction is exclusive to the suppliers, and the Company has no influence or management over the amounts received by suppliers from financial institutions; (iii) there was no change in due dates; and (c) there were no non-cash modifications to the supplier advance payment agreements. 3.1.2 Amendments to IFRS 16 – Lease liability in a sale and leaseback transaction The amendments specify that, in measuring the lease liability subsequent to the sale and leaseback, the seller-lessee determines ‘lease payments’ and ‘revised lease payments’ in a way that does not result in the seller-lessee recognising any amount of the gain or loss that relates to the right of use that it retains. The Company assessed the content of this pronouncement and did not identify any impact. 3.1.3 Amendments to IAS 1: Classification of liabilities as current or non-current and non-current liabilities with covenants The changes improve the information provided by the entity when its right to defer the settlement of a liability for at least twelve months is subject to compliance with covenants. The classification of liabilities as current or non-current is based on compliance with covenants that are required on the reporting date or before that date, but never in relation to future events, in addition to requiring disclosure of information in the explanatory notes that allow Users of financial statements assess the risk that the liability may become due within twelve months, including the agreed conditions (for example, their nature and the date by which the entity must comply with them), whether the entity would have complied with the conditions based on its circumstances at the end of the reporting period and how the entity expects to comply with the conditions after the end of the reporting period. The Company assessed the content of this pronouncement and did not identify any impact. 3.1.4 IFRIC agenda decision - disclosure of revenues and expenses for reportable segments (IFRS 8) In July 2024, the IASB approved an IFRIC agenda decision in relation to segment reporting. The decision deals with how an entity applies the requirements in paragraph 23 of IFRS 8 to disclose for each reportable segment specified amounts related to segment profit or loss. The Company assessed the content of this pronouncement and included the cost of the product sold in note 28.
Consolidated Financial Statements	3.2 Accounting policies adopted 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 subsidiaries Futuragene and Suzano Packaging and the affiliates Biomas, Ensyn, 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 CPC 18/IAS 28 and do not have a material effect on the consolidated result and, if any significant event occurred until December 31, 2024, the effect would be adjusted in the consolidated financial statements, as well as consistent accounting policies. On December 31, 2024 , Suzano had an investment in the associate Spinnova, in the amount of R$95,254, representing 18.77% 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. 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. The participation of non-controlling shareholders is highlighted.
Subsidiaries	3.2.2 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.
Joint Operation	3.2.3 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.
Associates and joint ventures	3.2.4 Associated and joint ventures 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. 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.
Translation of financial statements to functional and presentation currency	3.2.5 Translation of financial statements into the functional and presentation currency The Company has defined that, for all its wholly owned subsidiaries, the functional and presentation currency is the Brazilian Real, except for subsidiary Suzano Packaging, whose functional currency is the US Dollar, and for investments in associates abroad related to Ensyn Corporation, F&E Technologies LLC and Simplifyber, whose functional currency is the US Dollar, Spinnova and Woodspin, 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. 3.2.5.1 Transactions and balances in foreign currency These are translated using the following criteria: i. Monetary assets and liabilities are translated at the exchange rate in effect at year-end; ii. Non-monetary assets and liabilities are translated at the historical rate of the transaction; iii. Revenue and expenses are translated based on monthly average rate; and iv. The cumulative effects of gains or losses upon translation are recognized in the other comprehensive income. 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.
Hyperinflationary economies	3.2.6 Hyperinflationary economies Entities based in Argentina, a country considered to have a hyperinflationary economy, are subject to the requirements of IAS 29 - Financial Reporting in Hyperinflationary Economies. Non-monetary items, as well as income and expenses, are adjusted by the changes in the inflation index between the initial recognition and the closing date, so the balances are stated at their current value. However, the Company's wholly-owned subsidiary, based in Argentina, has the Real as its functional currency, and therefore is not considered an entity with a hyperinflationary currency, and does not present its individual financial statements in accordance with IAS 29 - Financial Reporting in Hyperinflationary Economies. The financial statements are presented at historical cost.
Business combinations	3.2.7 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.
Segment information	3.2.8 Segment information
Cash and cash equivalents	3.2.9 Cash and cash equivalents
Financial instruments	3.2.10 Financial instruments 3.2.10.1 Classification Financial instruments are classified based on the purpose for which the financial instruments were acquired, as set forth below: (i) Amortized cost; i. Fair value through other comprehensive income; and i. 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. 3.2.10.1.1 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. Any changes are recognized under financial income (expenses) in the income statement. It includes the balance of cash and cash equivalents, trade accounts receivable, dividends receivable and other assets, classified as financial assets and the balances of suppliers, loans, financing and debentures, lease payables, accounts payable for the acquisition of assets and subsidiaries, , dividends and interest on own capital payable and other liabilities, all of which are classified as financial liabilities. 3.2.10.1.2 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. 3.2.10.1.3 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. This category includes the balance of marketable securities, classified as financial assets financial and derivative financial instruments, including embedded derivatives, stock options, classified as financial assets and liabilities. 3.2.10.2 Impairment of financial assets 3.2.10.2.1 Financial instruments measured at amortized cost 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: i. Significant financial difficulty of the issuer or debtor; ii. Defaults on or late payment of interest or principal under the agreement; 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; iv. It becomes probable that the borrower will enter bankruptcy or other financial reorganization; v. The disappearance of an active market for that financial asset because of financial difficulties; and 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. 3.2.10.2.2 Financial assets at fair value through other comprehensive income The Company periodically evaluates, when measuring fair value, whether there is evidence that a financial asset is impaired. For such financial assets, a significant or prolonged decrease in the fair value of the security below its cost is evidence that the assets are impaired. If any such evidence exists, an impairment loss measured at the difference between the acquisition cost and the current fair value, less any loss previously recognized in other comprehensive income, shall be recognized in the income statement.
Derivative financial instruments	3.2.11 Derivative financial instruments and hedging activities Derivative financial instruments are recognized at fair value on the date on which the derivative agreement is entered into and are subsequently remeasured at fair value. Changes in fair value are recorded within the results of derivative financial instruments in the income statement. 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.
Trade and other receivables	3.2.12 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.
Inventories	3.2.13 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.
Non-current assets held for sale	3.2.14 Non-current assets held for sale These are measured at their carrying amount or fair value less costs to sell, whichever is lower, and are not depreciated or amortized. Such items are only classified in this account when the sale is highly probable and the assets are available for immediate sale in their current condition.
Biological assets	3.2.15 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.
Property, plant and equipment	3.2.16 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.
Leases	3.2.17 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: 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; ii. The Company has the right to obtain substantially all the economic benefits from the use of the asset during the contract period; and 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: • It has the right to operate the asset, or • 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: i. In future payments resulting from a change in index or rate; ii. In the estimate of the expected amount to be paid, at the guaranteed residual value; or 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: i. Variable payments that are based on the performance of the leased assets; ii. Guarantees of residual value; and 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.
Intangible assets and goodwill	3.2.18 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. 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 assumptions and judgments, disclosed in Note 16.
Current and deferred income tax and social contribution	3.2.19 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. 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.
Trade and other payables	3.2.20 Trade accounts payable and supplier finance arrangement Corresponds to the obligations payable for goods or services acquired in the normal course of the Company´s business, recognized at fair value and subsequently measured at amortized cost using the effective interest rate method, adjusted to present value, plus exchange rate variations when denominated in foreign currency. 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 and financing	3.2.21 Loans, financing and debentures Loans and financing are initially recognized at fair value, net of costs incurred in the transaction, and are subsequently stated at amortized cost. Any difference between the amounts raised and settled is recognized in the statement of income during the period in which the loans and financing are outstanding, using the effective tax rate method. 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.
Provision, contingent assets and liabilities	3.2.22 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 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: i. The amount that would be recognized in accordance with the accounting policy for the provisions above that comply with IAS 37; or 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.
Asset Retirement Obligations	3.2.23 Asset retirement obligations These primarily relate to future costs for the decommissioning of industrial landfill sites and related assets. A provision is recorded as a long-term obligation within property, plant and equipment. The provision and the corresponding property, plant and equipment are initially recorded at fair value, based on the present value of the estimated cash flow for future cash payments discounted at an adjusted risk-free rate. The long-term obligation accrues interest using a long-term discount rate, recognized under other liabilities. Property, plant and equipment are depreciated on a straight-line basis over the useful life of the principal, against cost of sales in the income statement.
Share-based payment transactions	3.2.24 Share based payments The Company’s executives and managers receive their compensation partially through share-based payment plans to be settled in cash and shares, or alternatively in cash only. Plan-related expenses are recognized in the income statement as a corresponding entry within financial liabilities during the vesting period when the services will be rendered. The financial liability is measured at its fair value on every balance sheet date, and its variations are recorded in the income statement as administrative expenses. At the option exercise date, if such options are exercised by the executive in order to receive shares in the Company, financial liabilities are reclassified under stock options granted in shareholders’ equity. In the case of options exercised in cash, the Company settles the related financial liability in favor of the Company’s executives.
Employee benefits	3.2.25 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.
Other assets and liabilities current and non-current	3.2.26 Other assets and liabilities, current and non-current Assets are recognized only when it is probable that the economic benefit associated with the transaction will flow to the entity, and its cost or value can be measured reliably. A liability is recognized when the Company has a legal or constructive obligation arising from a past event, and it is probable that an economic resource will be required to settle this liability.
Government grants and assistance	3.2.27 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.
Dividend and interest on own capital	3.2.28 Dividends and interest on own capital The distribution of dividends or interest on own capital is recognized as a liability, calculated based on the Corporate Law, the bylaws and the Company's Dividend Policy, which establishes that the minimum annual dividend is the lower of: (i) 25% of adjusted net income, or (ii) 10% the consolidated operating cash flow for the year, provided they are declared before the end of the year. Any portion in excess of the minimum mandatory dividends, if declared after the balance sheet date, must be recorded as part of the additional dividends proposed in shareholders' equity, until approved by the shareholders at a General Meeting. After approval, the reclassification to current liabilities is made. The tax benefit of interest on own capital is recognized in the income statement under income tax.
Share Capital	3.2.29 Share capital Common shares are classified in shareholders’ equity. Incremental costs directly attributable to a public offer are stated in shareholders’ equity as a deduction from the amount raised, net of taxes.
Recognition of revenue	3.2.30 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. The Company follows the five-step model: (i) identification of contracts with customers; (ii) identification of performance obligations under the contracts; (iii) determining the transaction price; (iv) allocation of the transaction price to the performance obligations provided for in the contracts; and (v) recognition of revenue when the performance obligations have been met. 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 operating segment Paper and Consumer Goods, 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) the corresponding International Commercial Terms (“Incoterms”); and (ii) lead times, when destined for the external and internal 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.
Financial income and expenses	3.2.31 Financial income and expenses Includes interest income on financial assets, at the effective interest rate, which includes the amortization of funding raising costs, gains and losses on derivative financial instruments, interest on loans and financing, exchange variations on loans and financing and other assets and financial liabilities and monetary variations on other assets and liabilities. Interest income and expenses are recognized in the statement of income using the effective interest method.
Earnings per share	3.2.32 Earnings (losses) per share Basic earnings (losses) per share are calculated by dividing the net profit (loss) attributable to the holders of ordinary shares of the Company to the weighted average number of ordinary shares during the year. Diluted earnings per share are calculated by dividing the net profit attributable to the holders of ordinary shares of the Company by the weighted average number of ordinary shares during the year, plus the weighted average number of ordinary shares that would be issued when converting all potential dilutive ordinary shares into ordinary shares.
Employee and management profit sharing	3.2.33 Employee and management profit sharing Employees are entitled to profit sharing based on certain goals agreed annually. For the Administrators, the 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.
Use of Estimates, Policy	3.2.34 Material accounting judgments, estimates and assumptions As disclosed in Note 2, Management used judgments, estimates and accounting assumptions regarding the future, uncertainty in which may lead to results that require significant adjustments to the book values of certain assets, liabilities, income and expenses in future years, are presented below: • Control, significant influence and consolidation (Note 1.1); • Share-based payment transactions (Note 22); • Transfers to control for revenue recognition (Note 27); • Fair value of financial instruments (Note 4); • Annual analysis of the impairment of non-financial assets (Notes 15 and 16); • Expected credit losses in the accounts receivable (Note 7); • Net realizable value provision for inventory (Note 8); • Annual analyses of the recoverability of taxes (Notes 9 and 12); • Fair value of biological assets (Note 13); • Useful lives of property, plant and equipment and intangible assets with defined useful life (Notes 15 and 16); • Annual analysis recoverable amount of goodwill (Note 16); • Leases (Note 19); • Provision for legal liabilities (Note 20); and • Pension and post-employment plans (Note 21). 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.
Accounting policies not yet adopted	3.3 Accounting policies not yet adopted The new and changed standards and interpretations issued, but not yet adopted up to December 31, 2024, 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 Amendments to IAS 21: Absence 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: i. the timeliness of obtaining foreign currency; ii. the practical ability (and not the intention) to obtain foreign currency; It is iii. the available markets or exchange mechanisms that create enforceable rights and obligations.

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.

Disclosure of number and weighted average exercise prices of other equity instruments [text block]	22.1 Phantom shares plan (“PS”) The number of phantom shares to be granted to each beneficiary is calculated based on a fixed 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. Since phantom stock option plans are settled in cash, their fair values are measured at the end of each reporting period. If the beneficiaries leave the Company during the vesting period, they lose the right to exercise the phantom shares.

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.
