The preparation of unaudited condensed consolidated interim financial information 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 Company reviews its judgments, estimates and assumptions continually as disclosed in the annual financial statements for the year ended December 31, 2024 (Note 3.2.34). For the three-month period ended March 31, 2025, there were no changes in these judgments, estimates and assumptions compared to disclosed on December 31, 2024.

The unaudited condensed consolidated interim financial information was prepared on historical cost basis, 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 unaudited condensed consolidated interim financial information was prepared under the going concern assumption.

3.1 New accounting policies and changes in accounting policies adopted

The new standards and interpretations issued, until the issuance of the Company’s unaudited condensed consolidated interim financial information, are described below.

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

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

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

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.

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

The book values of loans and financing are disclosed in Note 18.1.

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. During the three-month period ended March 31, 2025, the variations in cash and marketable securities were as expected, and the cash generated from operations was mostly used for investments and debt service.

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

4.3 Credit risk management

In the three-month period ended March 31, 2025, there were no significant changes in the credit risk management policies compared to those disclosed in the annual financial statements for the year ended of December 31, 2024 (Note 4).

4.4 Market risk management

In the three-month period ended March 31, 2025, there were no significant changes in the market risk management policies and procedures compared to those disclosed in the annual financial statements for the year ended December 31, 2024 (Note 4).

4.4.1 Exchange rate risk management

As disclosed in the financial statements for the year ended December 31, 2024 (Note 4), 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.

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

For market risk analysis, the Company uses scenarios to evaluate both its asset and liability positions in foreign currency, and the possible effects on its results. The probable scenario represents the amounts recognized, as they reflect the conversion into Brazilian Reais on the balance sheet date (R$ to US$ = R$5.7422).

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:


	03/31/2025
	Effect on profit or loss
	Probable (base value)	Possible (25%)	Remote (50%)
Cash and cash equivalents	8,157,219	2,039,305	4,078,610
Marketable securities	49,870	12,468	24,935
Trade accounts receivable	4,539,485	1,134,871	2,269,743
Trade accounts payable	(1,527,479)	(381,870)	(763,740)
Loans and financing	(72,660,737)	(18,165,184)	(36,330,369)
Liabilities for asset acquisitions and subsidiaries	(87,698)	(21,925)	(43,849)

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 March 31, 2025.

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

4.4.2 Interest rate risk management

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

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

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

For its market risk analysis, the Company uses scenarios to evaluate the sensitivity of changes in operations impacted by the following rates: Interbank Deposit Rate (“CDI”), Long Term Interest Rate (“TJLP”), Long Term Rate ("TLP"), Special System for Settlement and Custody (“SELIC”) and SOFR, which could impact the results. The probable scenario represents the amounts already booked, as they reflect Management’s best estimates.

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

For the measurement of the probable scenario, the United States Consumer Price Index (“US-CPI”) was considered on March 31, 2025. The probable scenario was extrapolated considering a appreciation of 25% and 50% in the US-CPI to define the possible and remote scenarios, respectively.

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.

Details of derivative financial instruments and their respective calculation methodologies are disclosed in the annual financial statements for the year ended December 31, 2024 (Note 4).

(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 variation in the fair values of derivatives on March 31, 2025 compared to the fair values measured on December 31, 2024 are explained substantially by the depreciation of the Brazilian Real against the US$ and by settlements during the period. There were also impacts caused by the variations in the Pre Fixed, Foreign Exchange Coupon and SOFR curves in the operations.

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

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 March 31, 2025, was R$6,364,876 (R$6,821,539 as of December 31, 2024).

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 three-month period ended March 31, 2025. There is no provision for tax related to the non-double taxation profits of such subsidiary in 2025. Disclosures about uncertain tax positions for income tax and social contribution (IFRIC 23) are presented in Note 20.2.

12.3 Tax incentives

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

12.4 OECD PILLAR TWO MODEL RULES

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

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

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

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

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

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

			Three-month period ended March 31, 2025

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

20.2 Contingencies with possible losses

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


	03/31/2025	12/31/2024
Taxes and social security (1)	9,942,885	9,837,082
Labor	177,780	171,480

	11,137,276	15,074,276

(1)The amounts above do not include the fair value adjustments allocated to possible loss risk contingencies representing R$2,106,933 (R$2,135,869 as of December 31, 2024), which were recorded at fair value resulting from business combinations with Fibria, as presented in Note 20.1.1 above.

(2)As disclosed in the annual financial statements, note 20.2.3(i), the Company is a defendant in a Public Civil Action (“ACP”) regarding compensation for damages caused to federal highways due to the transportation of timber exceeding the permitted weight. Based on a recent decision by the Superior Court of Justice (“STJ”), which established the thesis of civil liability without clear and objective liquidation criteria, as well as the change of the monetary correction index from IGPM/FGV to SELIC, the Company reassessed the exposure amount of this action to approximately R$ 340 million. This estimate made by management and supported by its external legal advisors, is based on scenarios with similarity to infraction notices suffered by other companies and assessed according to the quantification criteria applied by the Federal Public Ministry (“MPF”). Given the absence of clear and objective criteria for measuring such claims from the MPF in similar cases, management’s current estimate may vary to a higher or lower amount, subject to the final decision by the MPF/TRF1 regarding the Company's case.

In the three-month period ended March 31, 2025, there were no significant changes in the main nature of these contingencies compared to those disclosed in the annual financial statements for the year ended December 31, 2024 (Note 20.1).

			Three-month period ended March 31, 2025

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

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

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