NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

NOTE 1 BASIS OF PRESENTATION

The accompanying unaudited condensed consolidated financial statements have been prepared in conformity with accounting principles generally accepted in the United States and in accordance with the instructions to Form 10-Q and, in the opinion of management, include all adjustments that are necessary for the fair presentation of Sylvamo Corporation’s ("Sylvamo's", "the Company’s" or "our") financial position, results of operations, and cash flows for the interim periods presented. Except as disclosed herein, such adjustments are of a normal, recurring nature. Results for the first nine months of the year may not necessarily be indicative of full year results due to factors such as the Company’s planned maintenance outage schedule at its mills. All intercompany transactions have been eliminated. You should read these condensed consolidated financial statements in conjunction with the audited financial statements and the notes thereto included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2024 (the "Annual Report" or “2024 Form 10-K”), which have previously been filed with the Securities and Exchange Commission. These consolidated financial statements have been prepared in conformity with accounting principles generally accepted in the United States that require the use of management’s estimates. Actual results could differ from management’s estimates.

NOTE 2 SIGNIFICANT ACCOUNTING POLICIES

Our significant accounting policies are described in Note 2 Significant Accounting Policies to the audited consolidated financial statements included in our 2024 Form 10-K. There have been no material changes to the significant accounting policies for the nine months ended September 30, 2025.

Recently Issued Accounting Pronouncements Not Yet Adopted

Disaggregation of Income Statement Expenses

In November 2024, the FASB issued ASU 2024-03, “Income Statement - Reporting Comprehensive Income - Expense Disaggregation Disclosures (Subtopic 220-40): Disaggregation of Income Statement Expenses.” This guidance requires disaggregated disclosure of certain income statement captions for public business entities into specified categories within the footnotes to the financial statements. Additional disclosures are required in tabular format for each relevant expense caption on the face of the income statement that includes any of the following natural expenses: (1) purchases of inventory, (2) employee compensation, (3) depreciation, (4) intangible asset amortization, and (5) depreciation, depletion and amortization recognized as part of oil-and gas-producing activities or other types of depletion expenses. This update does not change or remove existing expense disclosure requirements; however, it may affect where that information appears in the footnotes to the financial statements. This guidance is effective for fiscal years beginning after December 15, 2026, and interim periods within fiscal years beginning after December 15, 2027. The Company is currently evaluating the provisions of this guidance.

Income Taxes

In December 2023, the FASB issued ASU 2023-09, “Income Taxes (Topic 740): Improvements to Income Tax Disclosures.” This guidance requires a public entity to disclose in their rate reconciliation table additional categories of information about federal, state and foreign income taxes and to provide more details about the reconciling items in some categories if the items meet a quantitative threshold. The guidance also requires all entities to disclose annually income taxes paid (net of refunds received) disaggregated by federal (national), state and foreign taxes and to disaggregate the information by jurisdiction based on a quantitative threshold. This guidance is effective for annual periods beginning after December 15, 2024. Early adoption is permitted and this guidance should be applied prospectively but there is the option to apply it retrospectively. The Company plans to adopt the provisions of this guidance in conjunction with our Form 10-K for the annual period ending December 31, 2025.

NOTE 3 REVENUE RECOGNITION

Total	$	846	$	965	$	2,461	$	2,803

Revenue Contract Balances

A contract asset is created when the Company recognizes revenue on its customized products for which we have an enforceable right to payment.

A contract liability is created when customers prepay for goods prior to the Company transferring those goods to the customer. The contract liability is reduced when control of the goods is transferred to the customer, satisfying our performance obligation. Contract liabilities of $ 3 million and $ 2 million are included in “Other current liabilities” as of September 30, 2025 and December 31, 2024, respectively.

The difference between the opening and closing balances of the Company’s contract assets and contract liabilities primarily results from the difference between the price and quantity at comparable points in time for goods for which we have an unconditional right to payment or receive pre-payment from the customer, respectively.

NOTE 6 EARNINGS PER SHARE

Basic earnings per share is computed by dividing net income by the weighted average number of shares of common stock outstanding during the period. Diluted earnings per share is computed by dividing net income by the weighted-average number of shares of common stock outstanding during the period, increased to include the number of shares of common stock that would have been outstanding had potentially dilutive shares of common stock been issued. The dilutive effect of restricted stock units is reflected in diluted earnings per share by applying the treasury stock method.

There are no adjustments required to be made to net income for purposes of computing basic and diluted earnings per share.

Basic and diluted earnings per share are calculated as follows:


	Three Months Ended September 30,				Nine Months Ended September 30,
In millions, except per share amounts	2025		2024		2025		2024
Net income	$	57	$	95	$	99	$	221
Weighted average common shares outstanding	40.0		41.0		40.4		41.1
Effect of dilutive securities	0.3		0.9		0.5		0.9
Weighted average common shares outstanding - assuming dilution	40.3		41.9		40.9		42.0
Earnings per share - basic	$	1.43	$	2.32	$	2.45	$	5.37
Earnings per share - diluted	$	1.41	$	2.27	$	2.42	$	5.26
Anti-dilutive shares (a)	0.5		0.2		0.4		0.2

(a) Common stock related to service-based restricted stock units and performance-based restricted stock units were outstanding but excluded from the computation of diluted earnings per share because their effect would be anti-dilutive under the treasury stock method or because the shares were subject to performance conditions that had not been met.

NOTE 7 SUPPLEMENTARY FINANCIAL STATEMENT INFORMATION

Temporary Investments

Temporary investments with an original maturity of three months or less and money market funds with greater than three-month maturities but with the right to redeem without notice are treated as cash equivalents and are stated at cost.

Asset Retirement Obligations

As of September 30, 2025 and December 31, 2024, we have recorded liabilities of $ 29 million and $ 28 million, respectively, related to asset retirement obligations. These amounts are included in “Other liabilities.” For asset retirement obligations which are conditional upon future events, we cannot reasonably estimate the current fair value of those potential obligations due to the uncertainty as to the timing or amounts that may be incurred.

NOTE 10 INCOME TAXES

An income tax provision of $ 31 million and $ 42 million was recorded for the three and nine months ended September 30, 2025, respectively, and the reported effective income tax rate was 35 % and 30 %, respectively. An income tax provision of $ 37 million and $ 84 million was recorded for the three and nine months ended September 30, 2024, respectively, and the reported effective income tax rate was 28 % and 28 %, respectively.

On July 4, 2025, the One Big Beautiful Bill Act (“OBBBA”) was enacted in the U.S. The OBBBA makes permanent key elements of the Tax Cuts and Jobs Act including accelerated tax expensing of qualifying domestic research costs, 100% bonus depreciation on qualifying capital expenditures, and enhancements to the business interest expense limitation. We are evaluating the full effects of the legislation and assessing alternative tax elections allowed under the new law.

The Brazilian Federal Revenue Service has challenged the deductibility of goodwill amortization generated in a 2007 acquisition by International Paper do Brasil Ltda., now named Sylvamo do Brasil Ltda. (“Sylvamo Brasil”), a wholly-owned subsidiary of the Company (the “Brazil Tax Dispute”). Sylvamo Brasil received assessments for the tax years 2007-2015 totaling approximately $ 110 million in tax, and $ 279 million in interest, penalties and fees as of September 30, 2025 (adjusted for variation in currency exchange rates and a law change pursuant to which the Brazil tax authority agreed to cancel a portion of the interest, penalties, and fees). International Paper challenged and is managing the litigation of this matter pursuant to the Tax Matters Agreement between us and International Paper. After a previous favorable ruling challenging the basis for these assessments, Sylvamo Brasil received other subsequent unfavorable decisions from the Brazilian Administrative Council of Tax Appeals. These decisions are being appealed. The appeal involves several separate cases. In October 2024, at the first level of appeal in the Brazilian federal court system, the court ruled in favor of Sylvamo Brasil in cases covering approximately two thirds of the disputed amounts. The remaining one third of the disputed amounts is still under challenge at the Brazilian administrative court level and was not part of the ruling. The Brazilian tax authorities have appealed the October 2024 ruling. This tax litigation matter may take many years to resolve. The Company believes that the transaction underlying these assessments was appropriately evaluated, and that the Company’s tax position would be sustained, based on Brazilian tax law.

Pursuant to the terms of the Tax Matters Agreement, International Paper will pay 60 %, and Sylvamo will pay 40 % on up to $ 300 million of any assessment related to this matter, and International Paper will pay all amounts of the assessment over $ 300 million. Also in connection with this agreement, all decisions concerning the conduct of the litigation related to this matter, including settlement strategy, pursuit and abandonment, will continue to be made by International Paper, which is vigorously defending Sylvamo Brasil’s historic tax position against the current assessments and any similar assessments that may be issued for tax years subsequent to 2015.

NOTE 11 COMMITMENTS AND CONTINGENT LIABILITIES

Environmental and Legal Proceedings

The Company is subject to environmental and legal proceedings in the countries in which we operate. Accruals for contingent liabilities, such as environmental remediation costs, are recorded in the consolidated financial statements when it is probable that a liability has been incurred or an asset impaired and the amount of the loss can be reasonably estimated. The Company has estimated some probable liability associated with environmental remediation matters that is immaterial in the aggregate as of September 30, 2025.

At the Company’s Mogi Guaçu mill, there are legacy basin areas that were formerly lagoons used for treatment of mill wastewater from pulp and paper manufacturing. In coordination with and in response to a request by the Environmental Company of the State of São Paulo (“CETESB”), which is the state environmental regulatory authority, there has been continuous regulatory monitoring and sampling of the former basins, which began prior to their closure in 2006, both to assess for contamination and evaluate whether additional remediation is needed beyond the basins’ ongoing natural vegetation growth. This monitoring and sampling detected metal contamination, with the main constituent of potential environmental impact being mercury. The Company has presented CETESB with proposals for studies and other actions to further assess the scope and type of contamination and the possible need for an additional remediation approach.

In October 2022, CETESB requested that the Company expand its efforts to include providing CETESB with a proposed pilot intervention (remediation) plan for a portion of the former basins. The purpose of the pilot intervention plan was to facilitate determination of the appropriate actions to take for the basins generally, guided by the results of the pilot intervention plan in the subset portion of the basins. The Company submitted a proposed pilot intervention plan to CETESB in late 2023, and CETESB approved its pre-intervention stages and certain additional measures that the Company later submitted. The requirement to conduct the pilot intervention plan is currently suspended, as agreed by CETESB. The Company continues to conduct environmental testing and analysis. The Company has submitted a formal request to CETESB to maintain the suspension of the pilot intervention plan and continue the ongoing environmental testing and analysis.

As of September 30, 2025, the Company has recorded an immaterial liability for the environmental testing and analysis and a third-party review of the results and risk. While this matter could in the future have a material impact on our results of operations and cash flows, the Company is unable to estimate its potential liability. The Company’s liability will depend upon what additional studies and what remediation, beyond vegetation of the basins, may be required by CETESB, which in turn will depend partly upon CETESB’s assessment of information from the Company’s ongoing environmental testing and analysis and the third-party review of the results and risk.

Taxes Other Than Payroll Taxes

See Note 10 Income Taxes for a discussion of a goodwill amortization tax matter in Brazil.

During the first quarter of 2024, the State of Sao Paulo issued a tax assessment to Sylvamo Brasil for approximately $ 51 million (adjusted for variation in currency exchange rates) regarding unpaid VAT arising from intercompany transactions. This assessment includes $ 19 million in tax and $ 32 million in i nterest and penalties. As of September 30, 2025, no reserve has been recorded by the Company because we believe the risk of loss is not probable.

We have other open tax matters awaiting resolution in Brazil, which are at various stages of review in various administrative and judicial proceedings. We routinely assess these tax matters for materiality and probability of loss or gain, and appropriate amounts have been recorded in our financial statements for any open items where the risk of loss is deemed probable. We currently do not consider any of these other tax matters to be material individually. However, it is reasonably possible that settlement of any of these matters concurrently could result in a material loss or that over time a matter could become material, for example, if interest were accruing on the amount at issue for a significant period of time. Also, future exchange rate fluctuations could be unfavorable to the U.S. dollar and significant enough to cause an open matter to become material. The expected timing for resolution of these open matters ranges from one year to ten years .

General

The Company is involved in various other inquiries, administrative proceedings and litigation relating to environmental and safety matters, taxes (including VAT), personal injury, product liability, labor and employment, contracts, sales of property and other matters, some of which allege substantial monetary damages. Assessments of lawsuits and claims can involve a series of complex judgments about future events, can rely heavily on estimates and assu mptions, and are otherwise subject to significant uncertainties. As a result, there can be no certainty that the Company will not ultimately incur charges in excess of presently recorded liabilities. The Company believes that loss contingencies arising from pending matters, including the matters described herein, will not have a material effect on the consolidated financial position or liquidity of the Company. However, in light of the inherent uncertainties involved in pending or threatened legal matters, some of which are beyond the Company's control, and the large or indeterminate damages sought in some of these matters, a future adverse ruling, settlement, unfavorable development, or increase in accruals with respect to these matters, could result in future charges that could be material to the Company's results of operations or cash flows in any particular reporting period.

NOTE 12 LONG-TERM DEBT

Long-term debt is summarized in the following table:


In millions	September 30, 2025		December 31, 2024
Term Loan F - due 2027 (a)	$	255	$	255

Total	$	778	$	782

(a) As of September 30, 2025 and December 31, 2024, presented net of $ 1 million and $ 2 million in unamortized debt issuance costs, respectively.

(b) As of September 30, 2025 and December 31, 2024, presented net of $ 1 million and $ 2 million in unamortized debt issuance costs, respectively.

(c) As of September 30, 2025 and December 31, 2024, presented net of $ 2 million and $ 2 million in unamortized debt issuance costs, respectively.

Revolving Credit Facility

In addition to the debt noted above, the Company has the ability to access a cash flow-based revolving credit facility (“Revolving Credit Facility”) with a total borrowing capacity of $ 400 million, which matures in 2029. As of September 30, 2025 and December 31, 2024, the Company had $ 7 million and no outstanding borrowings on the Revolving Credit Facility, respectively, and an available borrowing capacity of $ 393 million and $ 400 million, respectively. Any outstanding balance on the Revolving Credit Facility is recorded within “Notes payable and current maturities of long-term debt” in the condensed consolidated balance sheet.

Securitization Program

Sylvamo North America LLC, a wholly owned subsidiary of the Company, maintains a $ 110 million accounts receivable finance facility (the “Securitization Program”), maturing in 2027. The Company sells substantially all of its North American accounts receivable balances to Sylvamo Receivables, LLC, a special purpose entity, which pledges the receivables as collateral for the Securitization Program. The borrowing availability under this facility is limited by the balance of eligible receivables

within the program. The average interest rate for the quarter ended September 30, 2025 was 5.33 %, and the average interest rate for the year ended December 31, 2024 was 6.10 %.

Term Loans

In the third quarter of 2024, as a result of debt refinancing, the Company entered into a new senior secured term loan facility which provided an aggregate principal amount of $ 235 million (“Term Loan F-2”) maturing in 2031. A portion of the proceeds from Term Loan F-2 were used to repay $ 104 million of Term Loan F and $ 36 million of Term Loan A. The Company used the remaining proceeds to redeem the $ 90 million outstanding principal of our 2029 Senior Notes and to pay related premiums and fees. Debt extinguishment costs for the refinancing include $ 3 million of premiums paid related to the 2029 Senior Notes redemption and $ 2 million of deferred financing costs which were written off. This cost was recorded within “Interest expense (income), net.” In connection with the debt refinancing, we incurred $ 5 million of debt issuance costs to be amortized over each instrument’s term until maturity.

Interest Rates

The interest rates applicable to the Term Loan F, Term Loan F-2, Term Loan A and Revolving Credit Facility are based on a fluctuating rate of interest measured by reference to SOFR plus a fixed percentage of 1.85 %, 2.25 %, 1.85 % and 1.85 %, respectively, payable monthly, with a SOFR floor of 0.00 %. The obligations under the Term Loan F, Term Loan F-2, Term Loan A, and Revolving Credit Facility are secured by substantially all the tangible and intangible assets of Sylvamo and its subsidiaries, subject to certain exceptions, and are guaranteed by Sylvamo and certain subsidiaries.

Patronage Credits

We are receiving interest patronage credits under the Term Loan F and Term Loan F-2. Patronage distributions, which are made primarily in cash but also in equity in the lenders, are generally received in the first quarter of the year following that in which they were earned. Expected patronage credits are accrued in accounts and notes receivable as a reduction to interest expense in the period earned. After giving effect to expected patronage distributions of 90 basis points, of which 75 basis points is expected as a cash rebate, the effective net interest rate on the Term Loan F was approximately 5.11 % and 5.31 % as of September 30, 2025 and December 31, 2024, respectively, and the effective net interest rate on the Term Loan F-2 was approximately 5.51 % and 5.71 % as of September 30, 2025 and December 31, 2024, respectively.

Interest Rate Swaps

In connection with some of the Company’s loans, we are a party to interest rate swaps with various counterparties. These interest rate swaps are designated as cash flow hedges utilized to manage interest rate risk by allowing the Company to exchange the difference in the variable rates on the term loans determined in reference to SOFR and the related fixed interest rate per notional amount. Fair value assets and liabilities related to interest rate swaps are recorded within “Deferred charges and other assets” and “Other liabilities,” respectively.


			September 30, 2025						December 31, 2024
(Dollars in millions)	Fixed Interest Rate	Maturity (a)	Notional Amount		Fair Value of Assets		Fair Value of Liabilities		Notional Amount		Fair Value of Assets		Fair Value of Liabilities
Interest rate swaps
Term Loan F	3.72 % to 3.75 %	2025	$	200	$	—	$	—	$	200	$	1	$	—
Term Loan F-2	3.80 % to 3.82 %	2029	$	223	$	—	$	4	$	232	$	2	$	—
Term Loan A	4.13 % to 4.16 %	2028	$	211	$	—	$	4	$	219	$	—	$	1

(a) The total notional amounts of Term Loan F-2 and Term Loan A amortize quarterly until maturity.

Debt Covenants

The Company is subject to certain covenants limiting, among other things, the ability of most of its subsidiaries to: (a) incur additional indebtedness or issue certain preferred shares; (b) pay dividends on or make distributions in respect of the Company’s or its subsidiaries’ capital stock or make investments or other restricted payments; (c) create restrictions on the ability of the Company’s restricted subsidiaries to pay dividends to the Company or make certain other intercompany transfers; (d) sell certain assets; (e) create liens; (f) consolidate, merge, sell or otherwise dispose of all or substantially all of the

Company’s assets; and (g) enter into certain transactions with its affiliates. The Company is currently subject to a maximum consolidated total leverage ratio of 3.75 to 1.00.

Our ability to make restricted payments under the credit agreement is governed by the provisions of our debt agreements in effect as if the Brazil Tax Dispute is settled, provided we maintain $ 275 million of available liquidity at the time we make restricted payments.

As of September 30, 2025, we were in compliance with our debt covenants.

NOTE 13 PENSION AND POSTRETIREMENT BENEFIT PLANS

Defined Benefit Plans

The Company sponsors and maintains pension plans for the benefit of certain of the Company’s employees. The service and non-service cost components of net periodic pension expense for these employees is recorded within cost of products sold and selling and administrative expenses. The assets and liabilities related to plans sponsored by the Company are reflected in deferred charges and other assets and other liabilities, respectively.

Net periodic pension expense (benefit) for all pension plans sponsored by the Company for the nine months ended September 30, 2025 and September 30, 2024 was immaterial .

The Company’s funding policy for the pension plans is to contribute amounts sufficient to meet legal funding requirements, plus any additional amounts that the Company may determine to be appropriate considering the funded status of the plans, tax deductibility, cash flow generated by the Company, and other factors. The Company continually reassesses the amount and timing of any discretionary contributions. Generally, the non-U.S. pension plans are funded using the projected benefit as a target, except in certain countries where funding of benefit plans is not required.

NOTE 14 INCENTIVE PLANS

The Company has adopted the Sylvamo 2021 Incentive Compensation Plan, which includes shares under its long-term incentive plan (“LTIP”) that grants certain employees, consultants, or non-employee directors of the Company different forms of awards, including time-based and performance-based restricted stock units. As of September 30, 2025, 2,214,054 shares remain available for future grants.

Total stock-based compensation cost recognized by the Company was as follows:


	Three Months Ended September 30,				Nine Months Ended September 30,
In millions	2025		2024		2025		2024
Total stock-based compensation expense (included in selling and administrative expense)	$	4	$	5	$	17	$	17

As of September 30, 2025, $ 22 million of compensation cost, net of estimated forfeitures, related to all stock-based compensation arrangements for Company employees had not yet been recognized. This amount will be recognized in expense over a weighted-average period of 1.5 years.

NOTE 15 FINANCIAL INFORMATION BY BUSINESS SEGMENT

The Company’s business segments, Europe, Latin America and North America, are organized by geography. These segments are consistent with the internal structure used to manage these businesses. Each of our segments derive their revenue from the manufacture and sale of paper and pulp products.

Business segment operating profits are used by the Company’s management to measure the earnings performance of its businesses. Management believes that business segment operating profit provides investors and analysts useful insights into our operating performance. We define business segment operating profit as our income from continuing operations before income

taxes calculated in accordance with GAAP, excluding net interest expense (income) and net business special items and net corporate special items.

The chief operating decision maker uses business segment operating profit to allocate resources (primarily capital spending) for each segment predominantly during the annual strategic planning, budgeting and forecasting processes. The chief operating decision maker also considers actual performance variances in business segment operating profits on a monthly basis to assess the performance of the segments. The Company’s chief operating decision maker group is made up of the Chairman and Chief Executive Officer and Chief Operating Officer.

Sales by business segment are determined using a management approach and include intersegment sales (which are eliminated in consolidation).

ITEM 2. MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

The following discussion and analysis of our financial condition and results of operations should be read in conjunction with our condensed consolidated financial statements and related notes included in “Financial Information” of this Quarterly Report on Form 10-Q (this “Form 10-Q”) and the Company’s Form 10-K for the three years ended December 31, 2024, 2023 and 2022. In addition to historical consolidated financial information, the following discussion contains forward-looking statements that reflect our plans, estimates, and beliefs that involve significant risks and uncertainties. Our actual results could differ materially from those stated and implied in any forward-looking statements. Factors that could cause or contribute to those differences include those discussed below and elsewhere in this Form 10-Q and in our 2024 Form 10-K, particularly under the headings “ Risk Factors ” and “ Forward-Looking Statements .”

EXECUTIVE SUMMARY

Third quarter 2025 net income was $57 million ($1.41 per diluted share) compared with $95 million ($2.27 per diluted share) for the third quarter of 2024. Net sales were $846 million in the current quarter compared with $965 million in the prior year. Cash from operations was $87 million compared to $163 million in the third quarter of last year. Adjusted EBITDA was $151 million, with an adjusted EBITDA margin of 18%, compared to $193 million and an adjusted EBITDA margin of 20% in the third quarter of 2024. Free cash flow was $33 million compared to $119 million in the third quarter of 2024.

Comparing our earnings performance in the third quarter of 2025 to the prior year, volume decreased, primarily due to lower North America volume resulting from International Paper’s Georgetown mill closure. Price and mix were unfavorable in Europe. More favorable operations and costs were partially offset by higher input and transportation costs. We continued to return cash to shareowners through an $18 million dividend payment and repurchased $42 million in shares during the quarter.

Looking ahead to the fourth quarter of 2025, we expect price and mix to be unfavorable primarily driven by paper prices in Europe and mix across our regions. Volume is expected to be favorable, largely due to Latin America and North America. Operations and costs are projected to be unfavorable primarily due to seasonally higher costs. We expect input and transportation costs to remain stable. Lastly, planned maintenance outage costs will be unfavorable by $18 million as we have one planned outage in North America during the fourth quarter.

BUSINESS SEGMENT RESULTS

Overview

Management provides business segment operating profit, a non-GAAP financial measure, to supplement our GAAP financial information, and it should be considered in addition to, but not instead of, the financial statements prepared in accordance with GAAP. Management believes that business segment operating profit provides investors and analysts useful insights into our operating performance. Business segment operating profit is reconciled to Income before income taxes, the most directly comparable GAAP measure. Business segment operating profit may be determined or calculated differently by other companies and therefore may not be comparable among companies.

The following table presents a comparison of Income before taxes to business segment operating profit:


	Three Months Ended September 30,				Nine Months Ended September 30,

In millions	2025		2024		2025		2024
Income Before Income Taxes	$	88	$	132	$	141	$	305
Interest (income) expense, net	9		14		28		32
Net special items expense (income) (b)	1		4		3		7
Business Segment Operating Profit (a)	$	98	$	150	$	172	$	344
Europe	$	(21)	$	3	$	(83)	$	7
Latin America	35		49		63		100
North America	84		98		192		237
Business Segment Operating Profit (Loss) (a)	$	98	$	150	$	172	$	344

(a) We define business segment operating profit as our income before income taxes calculated in accordance with GAAP, excluding net interest expense (income) and net special items. We believe that business segment operating profit is an important indicator of operating performance as it is a measure reported to our management for purposes of making decisions about allocating resources to our business segments and assessing the performance of our business segments.

(b) Net special items represent income or expenses that are incurred periodically, rather than on a regular basis. Net special items in the periods presented primarily include a gain to adjust the recognition of a foreign value-added tax refund in Brazil, charges related to the termination of the Georgetown mill offtake agreement, environmental reserves in Brazil, certain severance costs related to our salaried workforce, legal fees related to the Brazil Tax Dispute and integration costs related to the Nymölla acquisition.

Non-GAAP Financial Measures

Management provides Adjusted EBITDA, a non-GAAP financial measure, to supplement our GAAP financial information, and it should be considered in addition to, but not instead of, the financial statements prepared in accordance with GAAP. Management uses this measure in managing the operating performance of our business and believes that Adjusted EBITDA provides investors and analysts meaningful insights into our operating performance and is a relevant metric for the third-party debt. Adjusted EBITDA is reconciled to Net income, the most directly comparable GAAP measure. Adjusted EBITDA may be determined or calculated differently by other companies and therefore may not be comparable among companies.


	Three Months Ended September 30,						Nine Months Ended September 30,
In millions	2025			2024			2025			2024
Net Income	$	57		$	95		$	99		$	221

Net Sales	$	846		$	965		$	2,461		$	2,803
Adjusted EBITDA Margin	18		%	20		%	13		%	17		%

(a) Net special items represent income or expenses that are incurred periodically, rather than on a regular basis. Net special items in the periods presented primarily include a gain to adjust the recognition of a foreign value-added tax refund in Brazil, charges related to the termination of the Georgetown mill offtake agreement, environmental reserves in Brazil, certain severance costs related to our salaried workforce, legal fees related to the Brazil Tax Dispute and integration costs related to the Nymölla acquisition.

(b) We define Adjusted EBITDA (non-GAAP) as net income (GAAP), net of taxes plus the sum of income taxes, net interest expense (income), depreciation, amortization and cost of timber harvested, stock-based compensation, and, when applicable for the periods reported, special items.

Free cash flow is a non-GAAP measure and the most directly comparable GAAP measure is cash provided by operating activities. Management believes that free cash flow is useful to investors as a liquidity measure because it measures the amount of cash generated that is available, after reinvesting in the business, to maintain a strong balance sheet and service debt, and return cash to shareowners. It should not be inferred that the entire free cash flow amount is available for discretionary expenditures. By adjusting for certain items that are not indicative of the Company’s ongoing performance, free cash flow also enables investors to perform meaningful comparisons between past and present periods.

The following is a reconciliation of Cash provided by operations to Free Cash Flow:


	Three Months Ended September 30,				Nine Months Ended September 30,
In millions	2025		2024		2025		2024
Cash provided by operating activities	$	87	$	163	$	174	$	305
Adjustments:
Cash invested in capital projects	(54)		(44)		(168)		(157)
Free Cash Flow	$	33	$	119	$	6	$	148

The non-GAAP financial measures presented in this Form 10-Q as referenced above have limitations as analytical tools and should not be considered in isolation or as a substitute for an analysis of our results calculated in accordance with GAAP. In addition, because not all companies utilize identical calculations, the Company’s presentation of non-GAAP measures in this Form 10-Q may not be comparable to similarly titled measures disclosed by other companies, including companies in the same industry as the Company.

LIQUIDITY AND CAPITAL RESOURCES

Overview

Our ability to fund the Company’s cash needs depends on our ongoing ability to generate cash from operations and obtain financing on acceptable terms. Based upon our history of generating strong operating cash flow, we believe we will be able to meet our short-term liquidity needs. We believe we will meet known or reasonably likely future cash requirements through the combination of cash flows from operating activities, available cash balances and available borrowings through the issuance of third-party debt, as needed.

A major factor in our liquidity and capital resource planning is our generation of operating cash flow, which is highly sensitive to changes in the pricing and demand for our products. While changes in key operating cash costs, such as raw materials, energy, mill outages and distribution expenses do have an effect on operating cash generation, we believe that our focus on commercial and operational excellence, as well as our ability to manage costs and working capital, will provide sufficient cash flow generation to meet our operational and capital spending needs.

The terms of the agreements governing our debt contain customary limitations as well as other provisions. These provisions may also restrict our business and, in the event we cannot meet the terms of those provisions, may adversely impact our financial condition, results of operations or cash flows.

Operating Activities

Cash provided by operating activities totaled $174 million for the nine months ended September 30, 2025, compared with cash provided by operating activities of $305 million for the nine months ended September 30, 2024. The decrease in cash provided by operating activities in 2025 relates primarily to lower net income and timing of cash flows related to working capital.

Cash used for working capital components (accounts and notes receivable, inventories, accounts payable and accrued liabilities, and other) was $66 million for the nine months ended September 30, 2025, compared with cash used for working capital components of $44 million for the nine months ended September 30, 2024. The nine months ended September 30, 2025 working capital components primarily reflect $69 million of cash provided by our accounts and notes receivables, offset by $34 million, $63 million and $38 million of cash used for our inventories, accounts payable and accrued liabilities and other operating activities, respectively. The nine months ended September 30, 2024 working capital components primarily reflect $28 million, $21 million and $11 million of cash used for our accounts and notes receivables, inventories and other operating activities, respectively, offset by $16 million of cash provided by our accounts payable and accrued liabilities balances.

Investment Activities

The total cash used for investing activities for the nine months ended September 30, 2025 was consistent with the nine months ended September 30, 2024.

The following table shows capital spending by business segment:


	Nine Months Ended September 30,
In millions	2025		2024
Europe	$	26	$	17
Latin America	92		102
North America	49		37
Corporate	1		1
Capital Spending	$	168	$	157

Capital spending primarily consists of purchases of machinery and equipment related to our global mill operations and reforestation and timber purchase costs in Latin America.

Financing Activities

Cash used for financing activities for the nine months ended September 30, 2025 primarily reflects the payments of $29 million, $8 million, $9 million, and $16 million on our outstanding principal debt balances for the AR Securitization, Term Loan A, Term Loan F-2, and Revolving Credit Facility, respectively. These amounts are primarily offset by draws on our AR Securitization and Revolving Credit Facility of $41 million and $23 million, respectively. During the nine months ended September 30, 2025 the Company also paid $55 million in dividends and repurchased $82 million of our shares pursuant to our share repurchase program. Cash used for financing activities for the nine months ended September 30, 2024 primarily reflects the payments of $117 million, $44 million, $23 million, and $10 million on our outstanding principal debt balances for Term Loan F, Term Loan A, the AR Securitization, and Revolving Credit Facility, respectively. Additionally, payments of $93 million were made to redeem, at a premium, the full value of our 7.00% Senior Notes and pay $5 million in debt issuance costs in connection with the debt refinancing in the third quarter. These amounts are primarily offset by the issuance of Term Loan F-2, draws on our Revolving Credit Facility, and AR Securitization of $235 million, $10 million, and $6 million, respectively. During the nine months ended September 30, 2024 the Company also paid $43 million in dividends and repurchased $30 million of our shares pursuant to our share repurchase program.

Contractual Obligations

Our 2024 Form 10-K included disclosures of our contractual obligations and commitments as of December 31, 2024. We continue to make the contractually required payments, and, therefore, the 2024 obligations and commitments described in our 2024 Form 10-K have been reduced by the required payments.

Capital Expenditures

For the nine months ended September 30, 2025, we have invested approximately $168 million, or 6.8% of net sales, in total capital expenditures. Over that period, we spent approximately $124 million, or 5.0% of net sales, in maintenance, regulatory and reforestation capital expenditures, and approximately $44 million, or 1.8% of net sales, in high-return capital projects. Our annual maintenance, regulatory and reforestation capital expenditures are expected to be in the range of approximately $165 to $190 million per year (before inflation) for the next several years, which we believe will be sufficient to maintain our operations and productivity. In addition, we expect to spend approximately $55 million to $65 million on high-return projects in 2025.

PILLAR TWO DIRECTIVE

The Organization for Economic Co-Operation and Development (“OECD”) has been working on a project to act to prevent what it refers to as base erosion and profit shifting (“BEPS”). Most recently, the OECD, through an association of almost 140 countries known as the “inclusive framework,” has announced a consensus to address, among other things, perceived challenges presented by global digital commerce (“Pillar 1”) and the perceived need for a minimum global effective tax rate of 15% (“Pillar 2”). On December 15, 2022, the European Union formally adopted the Pillar Two Directive, and a majority of EU member states have enacted the directive into domestic law as of December 31, 2023. Other countries are taking similar actions. We have evaluated the developments and do not anticipate any material impact on our financial position, results of operations, or cash flows.

CRITICAL ACCOUNTING POLICIES AND SIGNIFICANT ACCOUNTING ESTIMATES

The preparation of financial statements in conformity with U.S. GAAP requires the Company to establish accounting policies and to make estimates that affect both the amounts and timing of the recording of assets, liabilities, revenues and expenses. Some of these estimates require subjective judgments about matters that are inherently uncertain.

Accounting policies whose application may have a significant effect on the reported results of operations and financial position of the Company, and that can require judgments by management that affect their application, include the accounting for impairment or disposal of long-lived assets and goodwill and income taxes.

The Company has included in the 2024 Form 10-K a discussion of these critical accounting policies, which are important to the portrayal of the Company’s financial condition and results of operations and require management’s judgments. The Company has not made any changes in these critical accounting policies during the first nine months of 2025.

FORWARD-LOOKING STATEMENTS

This Quarterly Report on Form 10-Q contains information that includes or is based upon forward-looking statements. Forward-looking statements forecast or state expectations concerning future events. These statements often can be identified by the fact that they do not relate strictly to historical or current facts. They typically use words such as “anticipate,” “assume,” “could,” “estimate,” “expect,” “project,” “intend,” “plan,” “believe,” “should,” “will” and other words and terms of similar meaning, or they relate to future periods. Some examples of forward-looking statements include those relating to our business and operating outlook, future obligations and anticipated expenditures.

Forward-looking statements are not guarantees of future performance. Any or all forward-looking statements may turn out to be incorrect, and actual results could differ materially from those expressed or implied in forward-looking statements. Forward-looking statements are based on current expectations and the current economic environment. They can be affected by inaccurate assumptions or by known or unknown risks, uncertainties and other factors that are difficult to predict. Although it is not possible to identify all of these risks, uncertainties and other factors, the impact of the following factors, among others, on us or on our suppliers or customers, could cause our actual results to differ from those in the forward-looking statements: deterioration of global and regional economic, civil and political conditions and trade relations including the imposition of tariffs or other trade protections; physical, financial and reputational risks associated with climate conditions and climate change, including adverse environmental events such as floods and fires; reduced demand for our products due to the cyclical nature of the paper industry, the industry-wide secular decline in paper demand, or competition from other businesses; increased costs or reduced availability of the raw materials, energy, transportation (truck, rail and ocean) and labor needed to manufacture and deliver our products; a material disruption at any of our manufacturing facilities; information technology risks including potential cybersecurity breaches affecting us or third parties with which we do business; extensive environmental, tax and other laws and regulations in Brazil, Europe, the United States and other jurisdictions to which we are subject, including our compliance costs and risk of liability and loss for violations; our reliance on a small number of customers; and the factors disclosed in Item 1A. Risk Factors of our 2024 Form 10-K, as such disclosures may be amended, supplemented or superseded from time to time by other reports we file with the U.S. Securities and Exchange Commission (the “SEC”), including subsequent annual reports on Form 10-K and quarterly reports on Form 10-Q.

We assume no obligation to update any forward-looking statements made in this quarterly report to reflect subsequent events or circumstances or actual outcomes.

ITEM 3. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

Information relating to quantitative and qualitative disclosures about market risk is shown on page 46 of the Company’s 2024 Form 10-K, which information is incorporated herein by reference. There have been no material changes in the Company’s exposure to market risk since December 31, 2024.

ITEM 4. CONTROLS AND PROCEDURES

Management carried out an evaluation, under the supervision and with the participation of our Chief Executive Officer and Chief Financial Officer, of the effectiveness of the design and operation of our disclosure controls and procedures (as defined in Exchange Act Rules 13a-15(e) and 15d-15(e)) as of September 30, 2025. Based upon that evaluation, our Chief Executive Officer and Chief Financial Officer concluded that our disclosure controls and procedures were effective as of such date and designed to ensure that information required to be disclosed by us in reports we file or submit under the Exchange Act is: recorded, processed, summarized and reported within the time periods specified in SEC rules and forms; and accumulated and communicated to our management, including our Chief Executive Officer and Chief Financial Officer, to allow timely decisions regarding required disclosure.

Changes in Internal Control over Financial Reporting:

In the third quarter of 2025, there were no changes in the Company’s internal control over financial reporting that have materially affected, or are reasonably likely to materially affect, its internal control over financial reporting.

PART II. OTHER INFORMATION

ITEM 1. LEGAL PROCEEDINGS

Sylvamo may be involved in legal proceedings arising from time to time in the ordinary course of business. Sylvamo is not involved in any legal proceedings that we believe will result, individually or in the aggregate, in a material adverse effect upon our financial condition or results of operations. Note 10 Income Taxes and Note 11 Commitments and Contingent Liabilities of the Notes to the Condensed Consolidated Financial Statements in this Form 10-Q are incorporated into this Item 1 by reference.

Item 103 of Regulation S-K requires disclosure of certain environmental matters when a governmental authority is a party to the proceedings and the proceedings involve potential monetary sanctions, unless we reasonably believe the monetary sanctions will not equal or exceed a threshold of $1 million (which is the threshold we elected to use as permitted by this regulation). The matters set forth in Note 11 Commitments and Contingent Liabilities and incorporated herein are disclosed in accordance with such requirement.

ITEM 1A. RISK FACTORS

The risk factors that affect our business and financial results are set forth under Part I, Item 1A, “Risk Factors,” in our 2024 Form 10-K and Part II, Item 1A, “Risk Factors,” in our Quarterly Report on Form 10-Q for the period ended June 30, 2025 (the “2025 Q2 10-Q”). There have been no material changes to the risk factors described in our 2024 Form 10-K and 2025 Q2 10-Q. The Risk Factors in the 2024 Form 10-K, 2025 Q2 10-Q, and the risks described in this Form 10-Q or our other SEC filings could cause our actual results to differ materially from those stated in any forward-looking statements.

On May 18, 2022, the Board approved a share repurchase program under which the Company may purchase up to an aggregate amount of $150 million of shares of its common stock (the “Repurchase Program”). In 2023 and again in the third quarter of 2025, the Board authorized an additional $150 million for the Repurchase Program, bringing the total program capacity to $450 million. As of September 30, 2025, $150 million remains available for repurchases. Pursuant to the Repurchase Program, the Company may repurchase in amounts, at prices and at such times as it deems appropriate, subject to market conditions and other considerations, including all applicable legal requirements. Repurchases may include purchases on the open market or privately negotiated transfers, under Rule 10b5-1 trading plans, under accelerated share repurchase programs, in tender offers and otherwise. The Repurchase Program does not obligate the Company to acquire any particular amount of shares of its common stock and may be modified or suspended at any time at the Company’s discretion. The Company repurchased $82 million of shares during the nine months ended September 30, 2025.
