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 nine-month period ended September 30, 2025, the variations in cash and marketable securities were as expected, and the cash generated from operations was mostly used for investments and debt service. All derivative financial instruments were traded over the counter and do not require deposit guarantee margins. The remaining contractual maturities of financial liabilities are presented as of the balance sheet date. The amounts as set forth below consist of undiscounted cash flow, and include interest payments and exchange rate variations, and therefore may not reconcile with the amounts disclosed in the balance sheet.

4.3 Credit risk management In the nine-month period ended September 30, 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 nine-month period ended September 30, 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. The assets and liabilities that are exposed to foreign currency, substantially in US$, are set forth below:

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$5.3186). This analysis assumes that all other variables, particularly interest rates, remain constant. The other scenarios considered the variation of the Brazilian Real against the US$ at the rates of 25% and 50% before taxes. The following table set forth the potential impacts at their absolute amounts:
| 09/30/2025
|  |  | Effect on profit or loss
| Probable (base value) |  | Possible (25%) |  | Remote (50%)
Cash and cash equivalents | 14,607,009 |  |  | 3,651,752 |  |  | 7,303,505 |
Marketable securities | 807,263 |  |  | 201,816 |  |  | 403,632 |
Trade accounts receivable | 4,497,967 |  |  | 1,124,492 |  |  | 2,248,984 |
Trade accounts payable | (1,067,725) |  |  | (266,931) |  |  | (533,863) |
Loans and financing | (69,042,086) |  |  | (17,260,522) |  |  | (34,521,043) |
Liabilities for asset acquisitions and subsidiaries | (68,670) |  |  | (17,168) |  |  | (34,335) |
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 positive 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 variation of the Brazilian Real against the US$ by 25% and 50%, before taxes, based on the base scenario on September 30, 2025. The following table set out the possible impacts assuming these scenarios:
| 09/30/2025
|  |  | Effect on profit or loss
| Probable (base value) |  | Possible 25% |  | Remote 50%

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 variation of 25% and 50% in market interest rates. The following table set forth the possible impacts assuming these scenarios in absolute amounts:
| 09/30/2025
|  |  | Effect on profit or loss
| Probable |  | Possible (25%) |  | Remote (50%)
CDI/SELIC |  |  |  |  |
Cash and cash equivalents | 1,121,685 |  |  | 41,783 |  |  | 83,566 |
Marketable securities | 5,374,880 |  |  | 200,214 |  |  | 400,428 |
Loans and financing | 8,982,744 |  |  | 334,607 |  |  | 669,214 |
TJLP |  |  |  |  |
Loans and financing | 122,763 |  |  | 2,750 |  |  | 5,500 |
SOFR |  |  |  |  |
Loans and financing | 25,368,450 |  |  | 268,906 |  |  | 537,811 |
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 variation of 25% and 50% in market interest rates. The following table sets out the possible impacts of these assumed scenarios:
| 09/30/2025
|  |  | Effect on profit or loss
| Probable |  | Probable 25% |  | Remote 50%

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 September 30, 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. The following table sets out the possible impacts, assuming these scenarios in absolute amounts:
| 09/30/2025
|  |  | 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 | 99,383 |  |  | (24,312) |  |  | (51,222) |
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). 4.5.1 Outstanding derivatives by contract type, including embedded derivatives The positions of outstanding derivatives are set forth below:

(1)The embedded derivative refers to a swap contract for the sale of price variations in US$ and US-CPI within the term of a forest partnership with a standing wood supply contract. The variation in the fair values of derivatives on September 30, 2025 compared to the fair values measured on December 31, 2024 are explained substantially by the appreciation of the Brazilian Real against the US$ and by settlements during the 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 September 30, 2025 are over-the-counter market operations, without any type of collateral margin or forced early settlement clause due to variations from market marking. 4.5.2 Fair Value Maturity Schedule (net amounts)
