EXECUTIVE SUMMARY

Despite the drop in average net pulp price, the third quarter of 2023 was marked by improved market sentiment, mainly due to the significant growth in demand in China. The evolution of fundamentals sustained a sequence of price increases which, however, are not yet fully reflected in the 3Q23 results. In this context, lower prices combined with practically stable volumes led to the reduction in adjusted EBITDA in this segment. Cash cost of production excluding scheduled maintenance downtime decreased once again, mainly due to lower consumption and lower input prices. The paper business unit posted resilient results in the domestic market; however, the decline in export market prices was the main reason for the decline in EBITDA per ton during the period. Consolidated adjusted EBITDA in the quarter came to R$3.7 billion, while operating cash flow reached R$1.9 billion.

As for financial management, net debt in USD increased slightly to US$11.5 billion, mainly due to the largest investment cycle in the company’s history aimed at generating significant and sustainable value in the long term. Leverage in USD stood at 2.7 times, mainly due to the decrease in Adjusted EBITDA in the last 12 months. The foreign exchange hedging policy continued to play its part, bringing in a positive cash inflow of R$0.7 billion.

Continuing the advances made in its strategy, within the context of the “Being an important player in pulp through solid projects” and “Be best in class in the total pulp cost vision” avenues, the physical progress of Cerrado Project remains as expected, reaching 78%, while financial progress was 68%. The company expects the project to go operational by June 2024, as announced earlier.

As part of its ambition to the “Be best in class in the total pulp cost vision”, the Company announced the construction of a new biomass boiler at its pulp mill in Aracruz to replace the current boiler, at an estimated investment of R$520 million. The new biomass boiler should go operational in foruth quarter of 2025.

Also, in line with the strategic avenue “Maintain relevance in pulp through good projects”, Suzano announced investments of R$490 million to produce fluff pulp from eucalyptus wood (Eucafluff®), with nominal production capacity of 340 tons a year. The investment represents the conversion of a pulp drying machine at the Limeira unit, which will give the company full flexibility in producing pulp for paper or fluff after the investment is concluded in 4Q25.

Finally, in line with its strategic avenue of “Advance in the links of the chain”, complementing the Notice to the Market disclosed on 06/30/2022, the Company announced the construction of a mill in the municipality of Aracruz, Espírito Santo, for the production of tissue paper and for conversion into toilet paper and paper towel. The mill, with annual production capacity of 60 thousand tons, received total investments estimated at R$650 million and is slated to go operational in 1Q26. Suzano plans to use the balance of ICMS credits it has in the state in the investments, which should reduce the estimated net disbursement to R$130 million.

PULP BUSINESS PERFORMANCE

PULP SALES VOLUME AND REVENUE

In 3Q23, the sentiment in the hardwood pulp market improved gradually, especially in China, due to the growth in demand for paper, the purchase of pulp by integrated producers and restocking by buyers.

During the period, China also witnessed a brisk pace of production of sanitary paper, driven by solid domestic demand, such as increased “away from home” consumption, growth of online sales channels, higher exports and supply of pulp required for the start-up of new paper machines. The paperboard segment also registered a brisk pace of production in the quarter, despite the increase in capacities throughout the year. Production of printing & writing paper, especially uncoated paper, grew on the back of stronger demand resulting from the rebound in economic activity. Added to this, prices increased in almost all lines of paper products during the quarter, further underlining the positive signals from the Chinese market.

In August, Europe witnessed an uptick in orders for printing & writing and special papers, and the signs of destocking coming to an end across the chain, which gradually helped reverse the scenario across the region. Nevertheless, due to high inventory levels at the start of the quarter and the challenging macroeconomic situation in the region, local prices declined sharply early in the quarter but changed course since September. Production of sanitary paper remained at healthy levels in both Europe and the U.S. markets during the quarter.

Since market prices remained below costs for high-cost hardwood pulp producers, unscheduled downtimes continued. Average PIX/FOEX prices of hardwood pulp in the quarter increased 3% in China but decreased 24% in Europe compared to 2Q23. The price difference between softwood and hardwood fibers was USD133/t in China and USD339/t in Europe (a record), which fueled the migration of consumption between the fibers.

Suzano's pulp sales remained practically stable in relation to the previous quarter due to restricted production volumes, as disclosed in the Material Fact notice of June 2, 2023, and to low inventory levels, which totaled 2,486 thousand tons, down 1% from 2Q23 and 11% from 3Q22.

Page 4 of 46

Average net price in USD of pulp sold by Suzano was US$544/t, decreasing 5% from 2Q23 and 33% from 3Q22. In the export market, average net price charged by the Company was US$547/t, down 3% and 33%, respectively, in the same comparison basis. Average net price in BRL was R$2,657/ton in 3Q23, down 6% from 2Q23, due to price scenario in China and Europe, and the decline in average USD against average BRL (-1%). Compared to 3Q22, the 38% decrease was mainly due to lower net average price in USD during the period.

Net revenue from pulp decreased 7% from 2Q23, due to the lower net average price in USD (-5%), the decline in average USD against average BRL (-1%) and lower sales volume in the period (-1%). Compared to 3Q22, revenue decreased 45% due to lower net average price in USD (-33%), lower sales volume (-11%) and the decline in average USD against average BRL (-7%).

Page 5 of 46

PULP CASH COST

Cash cost excluding downtime in 3Q23 stood at R$861/t, decreasing 6% from 2Q23, due to: i) the lower consumption of inputs (especially natural gas and chlorine dioxide) as a result of greater operational efficiency of mills and the start of benefits reaped from the higher energy efficiency project at the Jacareí mill; ii) lower chemical prices (especially of caustic soda caused by lower international prices - HIS); iii) lower fixed costs, mainly due to lesser maintenance expenses resulting from fewer scheduled downtimes during the period; and iv) the weakening of average USD versus average BRL (-1%).

Page 6 of 46

Wood costs remained practically stable. The bigger average supply radius, supply mix effect and price increases by suppliers were almost fully offset by lower specific consumption and better operational performance in the harvesting and transportation activities.

¹Excludes the impact of maintenance and administrative downtimes.

Cash cost excluding downtime in 3Q23 was 2% lower than in 3Q22, due to: i) lower prices of inputs, especially energy (lower natural gas prices due to the decline in Brent prices) and lower chemical prices (especially of caustic soda due to lower international prices (IHS)); ii) the lower consumption of inputs (especially natural gas and chlorine dioxide) as a result of greater operational efficiency of mills and the start of benefits reaped from the higher energy efficiency project at the Jacareí mill; and iii) the decline in average USD versus BRL (-7%).

The positive effects on cash cost were partially offset by: i) higher fixed costs resulting from lower dilution on account of higher labor costs, higher expenditure on maintenance (related to more frequent scheduled downtimes at Três Lagoas and Mucuri) and lower production volume; ii) higher wood costs resulting from adjustments in labor and third-party agreements, which affected both harvest and logistics, higher average supply radius and the supply mix effect, all of which were partially offset by lower costs with diesel during the period; and iii) lower revenue from utilities due to lower export volume, in turn, caused by lower production volume.

Page 8 of 46

Adjusted EBITDA from pulp decreased 9% from 2Q23 due to: i) the lower net pulp price in USD (-5%); ii) the decline in average USD against average BRL (-1%); and iii) lower sales volume in the period (-1%). These factors were partially offset by lower COGS cash basis (-6%), mainly due to lower cash cost of production excluding downtimes, as explained earlier. The 8% decline in adjusted EBITDA per ton is explained by the same factors, except the volume effect.

Compared to 3Q22, the 62% decrease in Adjusted EBITDA from pulp reflects: i) the lower net pulp price in USD (-33%); ii) lower sales volume (-11%); and iii) the decline in average USD against average BRL (-7%). These factors were marginally offset by lower cash cost of production. Adjusted EBITDA per ton fell 57% due to the same factors, ex-volumes.

PAPER BUSINESS PERFORMANCE

The following data and analyses incorporate the joint results of the consumer goods and paper businesses (tissue).

PAPER SALES VOLUME AND REVENUE

According to data published by Brazil's Forestry Industry Association (IBÁ), demand for printing & writing paper in Brazil, including imports, decreased 14% in the first two months of 3Q23 compared to the same period last year. Considering the first eight months of the year, domestic demand for printing & writing paper decreased 11% from the same period in 2022.

The impact of the drop in domestic demand remains concentrated in coated paper destined for the promotional segment, which is still affected by the decline in inventories and continued changes in consumption patterns driven by digitalization. As for uncoated paper lines, which account for the bulk of Suzano's sales volume, demand has been more resilient, only decreasing slightly year on year as a result of seasonal and inventory adjustments.

Across the international markets, demand for printing & writing paper was affected by inventory adjustments across the chain and by macroeconomic uncertainties, which restrict economic activity. In this context, the coated paper segment is the worst affected, especially in the U.S. and Western European markets, where digitalization is in a more advanced stage. In Latin America (excluding Brazil), demand continues to perform better than in mature markets, especially in the uncoated paper, as well as school and office stationery (cut size paper) segments.

Demand for paperboard in Brazil, Suzano’s flagship market for this product line, declined 4% in the first two months of 3Q23 compared to the same period last year, reflecting inventory adjustments across the chain, while demand for packaging remained stable during the period.

Consolidating the market segments mentioned above (paper market accessible to Suzano), domestic sales fell 11% in the first two months of 3Q23 compared to 3Q22. Despite a more challenging scenario, Suzano has been ramping up initiatives aimed at delivering solid results: through a unique go-to-market model and by advancing on its strategy of acquiring new customers. At the end of 3Q23, the Company achieved a record 45,000 active clients in the last 12 months. Furthermore, we continue to push ahead with our digital transformation initiatives and invest in our portfolio of innovative products intended for the packaging and substitute for single-use plastic segments

With the acquisition of Kimberly Clark's tissue business in Brazil, the consumer goods segment will account for a bigger share of the paper business results starting from 3Q23.

Page 11 of 46

Suzano’s paper sales (printing & writing, paperboard and tissue) in the domestic market totaled 235 thousand tons in 3Q23, up 12% from the previous quarter, due to new volumes as a result of the acquisition of Kimberly Clark’s tissue business in Brazil and to the increase in paperboard sales, partially offset by the drop in priting & writing paper sales volume. Compared to 3Q22, the 3% decrease follows the market decline associated with a restocking strategy, despite higher sales in the consumer goods business.

Export paper sales totaled 96 thousand tons, up 14% and 9%, respectively, from 2Q23 and 3Q22, accounting for 29% of total sales volume in 3Q23. The greater volume of exports in comparison with both periods is due to the commercial strategy of allocating volumes between external and internal markets.

¹Includes the Consumer Goods Unit.

Average net price increased 1% from the previous quarter, due to the allocation strategy among markets and segments, despite less favorable market conditions, in addition to the effect of the acquisition of Kimberly Clark’s tissue business in Brazil. Compared to 3Q22, the 3% increase was due to paperboard and tissue price increases in the period, which was influenced by the effect of the acquisition of tissue business mentioned earlier.

Page 12 of 46

Net revenue from paper sales amounted to R$2,343 million, up 14% from 2Q23, mainly reflecting the higher volume (+12%) and higher net average price in the domestic market (+7%), partially offset by the 13% decrease in net sales price in the export market. Compared to 3Q22, the increase of 3% was due to price increases in the domestic market (+17%), partially offset by lower revenue in the export market (-27%).

¹Includes the Consumer Goods Unit.

Paper adjusted¹ EBITDA (R$/ton)		2,366		2,481		-5	%		2,812		-16	%		2,599

¹Excludes non-recurring items.

Adjusted EBITDA from paper increased 7% from 2Q23, mainly due to net revenue growth driven by higher sales volume (+12%) and higher net average price (+1%), though partially offset mainly by higher SG&A (variable compensation and due to incorporation of expenses with the acquisition of Kimberly Clark’s tissue business in Brazil). Adjusted EBITDA per ton decreased 5%, mainly due to higher SG&A expenses, partially offset by the price effect.

Compared to 3Q22, despite increased volumes and better prices (+3%), the 16% decrease was caused by higher SG&A expenses, depreciation of the average USD against the BRL (7%) and higher cash COGS. The decrease in adjusted EBITDA per ton is explained by the same factors.

²Cash basis.

Operating cash flow per ton from the paper segment was R$1,800/t in 3Q23, down 6% from 2Q23, due to lower EBITDA per ton. Compared to the same period in 2022, the decrease of 26% was due to lower EBITDA per ton and higher sustaining capex per ton.

FINANCIAL PERFORMANCE

NET REVENUE

Suzano’s net revenue in 3Q23 was R$8,948 million, 75% of which came from exports (vs. 77% in 2Q23 and 84% in 3Q22). In relation to 2Q23, net revenue decreased 2%, due to lower net average pulp price in USD (-5%) and the decline in average USD against average BRL (-1%). These effects were partially offset by higher paper sales volume in the period (+12%). The 37% decrease in consolidated net revenue compared to 3Q22 is mainly explained by: i) lower average net pulp price in USD (-33%); ii) lower sales volume in the period (-10%); and iii) the decline in average USD against average BRL (-7%). These effects were partially offset by better paper prices in the domestic market (+17%).

¹Does not include Portocel service revenue.

Cash COGS in 3Q23 totaled R$4,434 million, or R$1,574/ton. Compared to 2Q23, cash COGS decreased 4% mainly due to the lower cost of production excluding downtimes, lower logistics costs (lower pulp sales, lower fuel costs and mix effect) and lower impact of scheduled maintenance downtimes. On a per-ton basis, the 4% reduction is explained by the same factors mentioned earlier.

Compared to 3Q22, cash COGS decreased 8%, chiefly due to lower sales volume and the decline in average USD against the BRL (7%), partially offset by a greater impact of scheduled maintenance downtimes and inventory turnover effect. In relation to the same period last year, cash COGS per ton increased 2% due to the same factors, except for the volume factor.

Cash selling expenses increased 7% from 2Q23, mainly due to higher spending with the acquisition of Kimberly Clark’s tissue business in Brazil, which increased personnel, third-party services and other expenses. Cash selling expenses per ton increased 6% due to higher costs, as mentioned earlier.

In relation to 3Q22, the 7% increase in cash selling expenses is also explained by the acquisition of Kimberly Clark’s tissue business in Brazil, higher allowance for loan losses and higher spending on labor and third-party services (IT, insurance, consulting and others). These effects were partially offset by the drop in average USD versus BRL (7%) and higher sales volume. Cash selling expenses per ton increased 19%, due to the factors mentioned above.

Compared to 2Q23, the 15% increase in cash general and administrative expenses is mainly due to higher personnel expenses (variable compensation) and incorporation of expenses with the acquisition of Kimberly Clark’s tissue business in Brazil. On a per-ton basis, these expenses increased 15% due to the same factors.

Compared to 3Q22, cash general and administrative expenses increased 25%, mainly due to higher personnel expenses (variable compensation and labor) and incorporation of expenses with the acquisition of Kimberly Clark’s tissue business in Brazil. On a per-ton basis, the 39% increase is explained by the same factors.

Other operating income (expenses) was an expense of R$10 million in 3Q23, compared to an income of R$1,205 million in 2Q23 and an expense of R$19 million in 3Q22. The variation in relation to 2Q23 is mainly due to the absence of the updated fair value of biological assets (which happens in the second and fourth quarters of each year). Compared to 3Q22, the variation is mainly explained by several less significant events.

¹Excludes non-recurring items.

Adjusted EBITDA in 3Q23 decreased 6% in relation to 2Q23, due to: i) the lower average net pulp price in USD (-5%); ii) higher SG&A expenses (+9%), mainly explained by higher administrative expenses resulting from the increase in personnel expenses (variable compensation) and the incorporation of expenses with the acquisition of Kimberly Clark’s tissue business in Brazil; and iii) the decline in average USD against average BRL (-1%). These effects were marginally offset by lower cash COGS (-2%), as explained above and and slight increase in volumes. Adjusted EBITDA per ton decreased 6% due to the same factors explained above, excluding volumes.

In relation to 3Q22, Adjusted EBITDA decreased 57% due to: i) the lower average net pulp price in USD (-33%); ii) lower sales volume (-10%); iii) the decline in average USD against average BRL (-7%); and iv) higher SG&A expenses (+12%), mainly explained by higher administrative expenses resulting from the increase in personnel expenses (variable compensation) and incorporation of expenses with the acquisition of Kimberly Clark’s tissue business in Brazil, as explained earlier. Adjusted EBITDA per ton decreased 52% due to the same factors, excluding volume.

Page 20 of 46

Financial expenses were 2% higher than in 2Q23, mainly due to the increase in interest expenses in foreign currency, mainly due to the decline in closing BRL against USD. In addition, there was an increase in interest in local currency due to the issuance of debentures as per Notice to the Market released on 06/29 and 09/18. These effects were partially offset by the increase in capitalized interest (linked to the progress of the Cerrado Project) and decline on other financial expenses (lower tax charges (IOF) arising from financial transactions). Compared to 3Q22, financial expenses decreased 3%, mainly due to the increase in capitalized interest, partially offset mainly by the increase in interest expenses in foreign currency resulting from the increase in the SOFR interest rate (3Q23: 5.24% p.a. | 3Q22: 2.15% p.a. - average reference).

Financial income grew 5% in relation to 2Q23, partially due to the increase in interest on financial investments, mainly explained by the increase in the U.S. interest rate (3Q23: 5.24% p.a. | 2Q23: 4.97% p.a. – average reference). Compared to 3Q22, the 58% increase was mainly caused by higher U.S. interest rate (3Q23: 5.24% p.a. | 3Q22: 2.15% p.a. – average reference).

Inflation adjustment and exchange variation had a negative impact of R$1,880 million on the Company’s financial result due to the 4% drop in BRL against USD at the close of 3Q23, which affected foreign currency debt by US$2,381 million (US$12,531 million at the end of 3Q23). This effect was partially offset by the positive result of exchange variation on other balance sheet items in foreign currency (R$501 million), notably the impact on the Company’s cash position (56% in USD at the end of 3Q23). Note that the accounting impact of exchange variation on foreign currency debt has a cash impact only on the respective maturities.

Derivative operations resulted in a loss of R$864 million in 3Q23, due to the negative impact of weaker BRL and the increase in IPCA coupon, despite the positive impact of the fixed, coupon and SOFR rate curves on debt hedge and cash flow transactions. The mark-to-market adjustment of derivative instruments on September 30, 2023, generated an income of R$1,676 million, compared to an income of R$3,261 million on June 30, 2023, down R$1,585 million. Note that the impact of BRL depreciation on the derivatives portfolio generates a cash impact only upon the respective maturities. The net effect on cash, which refers to the maturity of derivative operations in the third quarter, was a positive R$720 million (R$58 million expense from debt hedge, R$756 million gain from cash flow hedge and R$22 million gain from commodities).

Page 21 of 46

As a result of the above factors, net financial result in 3Q23, considering all financial expense and income lines, was an expense of R$3,494 million, compared to an income of R$4,536 million in 2Q23 and an expense of R$1,527 million in 3Q22.

DERIVATIVE OPERATIONS

Suzano carries out derivative operations exclusively for hedging purposes. The following table reflects the position of derivative hedging instruments on September 30, 2023:

²Hedge program related to capex in BRL (ZCC) and EUR (NDF) of the Cerrado Project.

³Includes commodity hedging and embedded derivatives.

The Company’s foreign exchange exposure policy seeks to minimize the volatility of its cash generation and ensure greater flexibility in cash flow management. Currently, the policy stipulates that surplus dollars may be partially hedged (at least 40% and up to 75% of exchange variation exposure over the next 24 months) using plain vanilla instruments, such as Zero Cost Collars (ZCC) and Non-Deliverable Forwards (NDF). At the end of 3Q23, 59% of the exchange variation exposure was covered.

Considering the foreign exchange exposure related to Capex in the Cerrado Project, since approximately 67% of Capex is pegged to local currency, the Board of Directors approved on October 28, 2021, a program for contracting additional specific hedge operations to protect from it such exposure. The program approved (established in the Derivatives Management Policy available on the Investor Relations website) initially involved a maximum amount (notional) of up to US$1 billion and a term of operations of up to 36 months. On July 27, 2022, the Board of Directors approved the expansion of the program, increasing the maximum amount (notional) to US$1.5 billion while maintaining the previously established term. To ensure transparency with regard to the Cerrado Project's hedge program, since 4Q21 the Company has been prominently disclosing the operations contracted.

Since about 33% of the Capex of the Cerrado Project is denominated in EUR, in 3Q22, the Company contracted hedge operations through NDFs to protect the exposure in EUR of the Capex of the Cerrado Project, converting it into USD. This type of hedge is established in the Derivatives Management Policy available on the Investor Relations website.

Page 22 of 46

ZCC transactions establish minimum and maximum limits for the exchange rate that minimize adverse effects in the event of significant appreciation of the BRL. As such, if the exchange rate is within such limits, the Company neither pays nor receives any financial adjustments. This characteristic allows for capturing greater benefits from export revenue in a potential scenario of BRL appreciation versus USD within the range contracted. In cases of extreme BRL appreciation, the Company is protected by the minimum limits, which are considered appropriate for the operation. However, this protection instrument also limits, temporarily and partially, potential gains in scenarios of extreme BRL depreciation when exchange rates exceed the maximum limits contracted.

On September 30, 2023, the outstanding notional value of operations involving forward USD sales through ZCCs related to Cash Flows (including those related to the Cerrado Project) was US$4,517 million, with an average forward rate ranging from R$5.55 to R$6.41 and maturities distributed between October 2023 and August 2025. On the same date, the outstanding notional value of operations involving forward USD sales through NDFs was US$44 million, whose maturities are distributed between October 2023 and April 2025 and with an average rate of R$5.61. Regarding hedge for foreign exchange exposure in EUR, the outstanding notional value of forward EUR purchases at the end of 3Q23 was €349 million (USD359 million), with an average contracted rate of 1.03 EUR/USD and maturities through July 2024. In 3Q23, operational, cash flow and Cerrado Project hedge operations resulted in a loss of R$689 million. The mark-to-market (“MtM” or “fair value”) value of these operations totaled R$2,057 million, with R$1,590 million related to cash flow operating hedge and R$467 million related to operating hedge of the Cerrado Project.

The following table presents a sensitivity analysis of the cash impact that the Company could have on its cash flow hedge portfolios (ZCC and NDF) if the exchange rate remains the same as at the end of 3Q23 (BRL/USD = 5.01) in the coming quarters, as well as the projected cash impact for R$0.10 variations below / above the strike of put/call options, respectively, defined in each quarter. Note that the figures presented in the table are the Company’s projections based on the end-of-period curves and could vary depending on market conditions.

To mitigate the effects of exchange and interest rate variations on its debt and its cash flows, the Company also uses currency and interest rate swaps. Swap contracts are entered into considering different interest rates and inflation indices in order to mitigate the mismatch between financial assets and liabilities.

On September 30, 2023, the Company had an outstanding amount (notional value) of US$5,155 million in swap contracts as shown in the table below. In 3Q23, the result of debt hedge transactions was a loss of R$225 million, mainly due to negative impact of weaker BRL, despite the positive impact of the variation in fixed-rate, coupon and SOFR curves. The mark-to-market adjustment (fair value) of these operations was a loss of R$617 million.

A portion of the forestry partnership agreements and standing timber supply agreements is denominated in USD per cubic meter of standing timber, adjusted by U.S. inflation measured by the Consumer Price Index (CPI), which is not related to inflation in the economic environment where the forests are located and, hence, constitutes an embedded derivative. This instrument, presented in the table above, consists of a sale swap contract of the variations in the US-CPI during the period of the contracts. See note 4 of the 3Q23 Financial Statements for more details and for a sensitivity analysis of the fair value in case of a sharp rise in the US-CPI and USD. On September 30, 2023, the outstanding (notional) value of the operation was US$129 million. The result of this swap in 3Q23 was a loss of R$45 million. The mark-to-market (fair value) adjustment of these operations generated a gain of R$143 million at the end of the quarter.

The Company is also exposed to the price of some commodities and, therefore, constantly assesses the contracting of derivative financial instruments to mitigate such risks. On September 30, 2023, the outstanding (notional) value of the operation was US$90 million. The result from this swap in 3Q23 was a gain of R$94 million. The mark-to-market (fair value) adjustment of these operations generated a gain of R$93 million at the end of the quarter.

NET INCOME (LOSS)

In 3Q23, the Company posted net loss of R$729 million, compared to net income of R$5,078 million in 2Q23 and net income of R$5,448 million in 3Q22. The variation in relation to 2Q23 was mainly due to the negative financial result, which was explained by the impact of weaker BRL on debt and derivative operations (compared to the positive result registered in the previous quarter). Moreover, the lack of revaluation of biological assets led to a reduction in other operating income/expenses line.

The variation in relation to 3Q22 is mainly explained by the decrease in operating result (decline in net revenue) and the negative financial result, reflecting the effect of weaker BRL on debt and derivative operations. These effects were partially offset by deferred IR/CSLL credits, mainly on negative results from exchange variation and derivative operations.

On September 30, 2023, gross debt totaled R$78.6 billion and was composed of 94% long-term maturities and 6% short-term maturities. Foreign currency debt corresponded to 80% of the Company's total debt at the end of the quarter. The percentage of gross debt in foreign currency, considering the effect of debt hedge, was 86%. Compared to 2Q23, gross debt increased 5%, mainly due to the effect of exchange variation of R$2,381 million combined with net funding operations carried out during the period. Suzano ended 3Q23 with 40% of total debt linked to ESG instruments.

Suzano contracts debt in foreign currency as a natural hedge, since net operating cash generation is mostly denominated in foreign currency (USD) due to its predominant status as an exporter. This structural exposure allows the Company to match loans and financing payments in USD with receivable flows from sales.

*Corresponding mainly to transaction costs (issue, funding, goodwill, discount and loss on business combinations, etc.).

On September 30, 2023, the total average cost of debt in USD was 5.1% p.a. (considering the debt in BRL adjusted by the market swap curve), compared to 4.9% p.a. on June 30, 2023. The average term of consolidated debt at the end of the quarter was 77 months, compared to 75 months at the end of 2Q23.

¹Considers the portion of debt with swap for fixed rate in foreign currency. The exposure of the original debt was: Fixed (US$) – 54%, SOFR– 26%, CDI – 11%, Other (Fixed R$, IPCA, TJLP, others) – 9%.

²Considers the portion of debt with currency swaps. The original debt was 80% denominated in USD and 20% in BRL.

Cash and cash equivalents and financial investments on September 30, 2023 amounted to R$20.9 billion, 56% of which was in foreign currency, allocated in remunerated accounts or in short-term fixed-income investments abroad. The remaining 44% was invested in local currency fixed-income bonds (mainly CDBs, but also in government bonds and others), remunerated at the CDI rate.

On September 30, 2023, the company also had a stand-by credit facility totaling R$6.4 billion (US$1.3 billion) available through February 2027. This facility strengthens the company's liquidity position and can be withdrawn during times of uncertainty. As a result, the cash and equivalents of R$20.9 billion plus the credit facilities described above amounted to a readily available cash position of R$27.3 billion on September 30, 2023. Moreover, the Company has a financing agreement with Finnvera (US$800 million) related to the Cerrado Project, as per the Notice to the Market of November 1, 2022, which has not yet been withdrawn, further strengthening its liquidity position.

On September 30, 2023, net debt stood at R$57.6 billion (US$11.5 billion), compared to R$54.3 billion (US$11.3 billion) on June 30, 2023. The main factors that explain the increase in net debt were, in this order: capex (R$4.5 billion), exchange rate variations (R$1.9 billion) and appropriate interest (R$0.8 billion). These effects were partially offset by adjusted EBITDA, positive adjustment of derivatives and release of working capital.

Page 29 of 46

Financial leverage, measured as the ratio of net debt to adjusted EBITDA in BRL, was 2.6 times on September 30, 2023, compared to 2.0 times in 2Q23. The same ratio in USD (the measure established in Suzano’s financial policy) rose to 2.7 times on September 30, 2023 (from 2.2 times in 2Q23).

CAPEX

In 3Q23, capital expenditure (cash basis) totaled R$4,404 million. The 29% decrease in relation to 2Q23 was due to: i) lower investments in Land and Forests due to the payment of the second installment for the acquisition of Parkia in the previous period; and ii) less spending on the Cerrado Project due to advances made to suppliers in 2Q23.

Compared to 3Q22, the 9% increase is mainly due to higher spending on maintenance, especially in the recovery of roads for forestry logistics and higher expenses with services, in addition to the progress in execution of the Cerrado Project.

The Company also announced three new investments:

The construction of a sanitary paper (tissue) factory and conversion into toilet paper and paper towels in the municipality of Aracruz, in the state of Espírito Santo, with a capacity of 60,000 tons per year, with total investments estimated at R$ 650 million and the beginning of operations scheduled for the first quarter of 2026. Suzano plans to use the balance of ICMS credits it has in the state in the investments, which should result in an estimated net disbursement of R$129 million in the project;

The construction of a new biomass boiler at the pulp mill in Aracruz to replace the current boiler, at an estimated investment of R$520 million. The new biomass boiler should go operational in 4Q25.

Investments totaling R$490 million to produce fluff pulp from eucalyptus wood (Eucafluff), with nominal production capacity of 340 thousand tons a year. The investment represents the conversion of a pulp drying machine at the Limeira unit, which will give the company full flexibility in producing pulp for paper or fluff after the investment is concluded in 4Q25.

The above investments do not affect the Capex guidance announced by the Company for 2023.

CERRADO PROJECT

The Cerrado Project is progressing according to schedule on its physical and financial curves, closing the third quarter of 2023 with the “inside the fence” execution (which corresponds to industrial and infrastructure investments) reaching physical progress of 78% and financial progress of 68% (R$9,991 million). The Company expects the new pulp mill located in Ribas do Rio Pardo, Mato Grosso do Sul, with annual capacity of 2,550 thousand tons, to go operational by June 2024.

¹Accrual basis, except for the Parkia deal (payment of R$1.6 billion in 2Q23) and the investment related to the Cerrado Project in 2Q23 and 3Q23, as per note 15 (Property, Plant and Equipment) to the Financial Statements. Also considering the acquisition of Kimberly Clark Brazil's tissue business in 2Q23 in the amount of R$ 1,073 million (operation is a business combination and not acquisition of assets).

²Considers costs of capitalized loans paid in the amount of R$305 million in 3Q23.

³Considers interest paid on debt and interest received on financial investments.

⁴Free cash flow prior to dividend payments and capex ex-maintenance (accrual basis).

Adjusted Free Cash Flow in 3Q23 was R$1,183 million, compared to R$5,283 million in 2Q23 and R$2,732 million in 3Q22. The decrease of 78% from the previous quarter is mainly due to: i) working capital variation, due to lower reduction in pulp prices in relation to the delta observed in 2Q23 (2T23 vs. 1T23: -US$ 150/t | 3T23 vs. 2T23: -US$ 27/t); ii) higher concentration of interest payment in the period; iii) decrease in positive adjustment of derivatives; and iv) lower adjusted EBITDA. These effects were partially offset mainly by lower sustaining capex on accrual basis.

Compared to 3Q22, the metric decreased 57% mainly due to lower adjusted EBITDA, partially offset by: i) release of working capital, mainly explained by the reduction in accounts receivable (compared to the high consumption in this line in 3Q22, which registered an increase in pulp prices, sales volume and average exchange rate); ii) lower sustaining capex (accrual basis); and iii) positive adjustment of derivatives.

EVOLUTION OF NET DEBT

Following were the changes in net debt in 3Q23:

¹ Accrual basis, except for the capex related to Cerrado Project (cash basis), as per the Cash Flow Statement. Considers the business combination with Kimberly Clark’s tissue business in Brazil.

²Net of exchange variations on cash and financial investments.

³Considers amounts (cash basis) related to derivative adjustments, lease agreements and other items.

ESG

In 3Q23, the process to approve Capex projects for Modernization started including the Internal Carbon Price, known as an instrument that quantifies the potential of a project to reduce greenhouse gas emissions and support Suzano’s decarbonization curve. In practice, the Internal Carbon Price is now incorporated into the Net Present Value (NPV) of projects, with a feasibility scenario. This mechanism will support the Company’s decision-making on investment projects.

TOTAL OPERATIONAL EXPENDITURE - PULP

As disclosed in the Material Fact notice of February 28, 2023, total operational expenditure forecast for 2027 is approximately R$1,750 per ton and the indicator has been evolving according to plan, considering the exchange rate and monetary premises used. Said estimate refers to the currency in real terms of 2023.
