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 three 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, 2025 (the "Annual Report" or “2025 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 2025 Form 10-K. There have been no material changes to the significant accounting policies for the three months ended March 31, 2026.

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.

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 $2 million and $3 million are included in “Other current liabilities” as of March 31, 2026 and December 31, 2025, 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 (LOSS) PER SHARE

Basic earnings (loss) per share is computed by dividing net income (loss) by the weighted average number of shares of common stock outstanding during the period. Diluted earnings (loss) per share is computed by dividing net income (loss) 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 (loss) per share by applying the treasury stock method.

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

Basic and diluted earnings (loss) per share are calculated as follows:

	Three Months Ended March 31,
In millions, except per share amounts	2026		2025
Net income (loss)	$	(3)	$	27
Weighted average common shares outstanding	39.6		40.6
Effect of dilutive securities (a)	—		0.9
Weighted average common shares outstanding - assuming dilution	39.6		41.5
Earnings (loss) per share - basic	$	(0.08)	$	0.66
Earnings (loss) per share - diluted	$	(0.08)	$	0.65
Anti-dilutive shares (b)	0.7		0.5

(a)    For the three months ended March 31, 2026, 0.3 million weighted average shares were excluded because their inclusion would have an anti-dilutive effect on net loss per share.

(b) 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 (loss) 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.

Additions to plants, property and equipment included within accounts payable were $11 million and $20 million each at March 31, 2026 and December 31, 2025.

Accounts Payable

The Company maintains supplier finance agreements with third-party financial institutions. These agreements allow the Company’s participating suppliers to sell their receivables to such third-party financial institutions to receive payment earlier than the negotiated commercial terms between the supplier and the Company. Such sales are at the sole discretion of the supplier, and on terms and conditions that are negotiated between the supplier and the respective financial institution. The terms and conditions of the supplier invoice, including payment terms and amounts due, are not impacted by a supplier’s participation in the program. Pursuant to the supplier finance agreements, the Company has agreed to pay financial institutions on the original due date of the applicable invoice. There are no guarantees associated with these programs. The Company's outstanding obligations to financial institutions related to supplier financing programs were $6 million and $3 million as of March 31, 2026 and December 31, 2025, respectively.

Interest Expense, Net

Interest payments of $13 million and $12 million were made during the three months ended March 31, 2026 and 2025, respectively.

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.

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 $113 million in tax, and $313 million in interest, penalties and fees as of March 31, 2026 (adjusted for variation in currency exchange rates). 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 Brazilian tax authorities have appealed the favorable ruling. One third of the disputed amounts was under challenge at the Brazilian administrative court level and was not part of the ruling. In November 2025, the administrative court upheld the assessments for the remaining one third of the disputed amounts. In January 2026, Sylvamo Brasil’s challenge of the administrative ruling was filed in the Brazilian federal court system. 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 March 31, 2026.

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 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 was thereafter suspended, as agreed by CETESB. The Company continues to conduct environmental testing and analysis and engage with CETESB in review of the results and establishing next steps.

As of March 31, 2026, 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 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 $56 million (adjusted for variation in currency exchange rates) regarding unpaid VAT arising from intercompany transactions. This assessment includes $20 million in tax and $36 million in interest and penalties. As of March 31, 2026, no reserve has been recorded by the Company because the risk of loss is not probable.

Since 2012, the Company has been involved in a dispute with Brazilian tax authorities concerning VAT credits taken in 2009 and 2010 related to imported materials used in the Company’s operations. The potential liability of $27 million includes $6 million of tax and $21 million of interest, legal fees and penalties (adjusted for variation in currency exchange rates). Also, since 2016, the Company has been involved in a similar, separate dispute concerning VAT credits taken in 2011 through 2013. The potential liability for this matter is $18 million which includes $4 million of tax and $14 million of interest, legal fees and penalties (adjusted for variation in currency exchange rates). Although initially not material, the potential liability for these disputes has become material over time due to variations in currency exchange rates and the accumulation of interest. The Company is vigorously defending both cases in Brazilian courts. If the Company fails to prevail in either case, it could set a precedent for the other case. As of March 31, 2026, no reserve has been recorded by the Company because the risk of loss in both cases 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 assumptions, 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	March 31, 2026		December 31, 2025
Term Loan F - due 2027 (a)	$	256	$	255
Term Loan F-2 - due 2031 (a)	216		219
Term Loan A - due 2029 (a)	204		206
Securitization Program	87		90
Financing Leases	15		16
Other Financing Arrangements	11		—
Less: current portion	(23)		(23)
Total	$	766	$	763

(a) As of March 31, 2026 and December 31, 2025, amounts are presented net of an aggregate total of $4 million and $4 million, respectively, in unamortized debt issuance costs across the three term loans.

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 March 31, 2026 and December 31, 2025, the Company had $132 million and $67 million of outstanding borrowings on the Revolving Credit Facility, respectively, and an available borrowing capacity of $268 million and $333 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 March 31, 2026 was 4.75%, and the average interest rate for the year ended December 31, 2025 was 5.28%. In May 2026, the Company amended the existing accounts receivable finance facility to extend the maturity to 2029.

Term Loans

In May 2026, as a result of debt refinancing, the Company entered into a new senior secured term loan facility which provided an aggregate principal amount of $357 million (“Term Loan F-3”) maturing in 2032. A portion of the proceeds from Term Loan F-3 were used to fully repay the outstanding principal balance of Term Loan F of $257 million, effectively extending the maturity date of the loan. The remaining proceeds are being used to repay $100 million of the amount outstanding under the Revolving Credit Facility.

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.

13

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 4.62% and 4.67% as of March 31, 2026 and December 31, 2025, respectively, and the effective net interest rate on the Term Loan F-2 was approximately 5.02% and 5.07% as of March 31, 2026 and December 31, 2025, 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.

			March 31, 2026						December 31, 2025
(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-2	3.80% to 3.82%	2029	$	217	$	—	$	2	$	220	$	—	$	3
Term Loan A	4.13% to 4.16%	2028	205		—		2		208		—		4

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

Other Financing Arrangements

During the first quarter of 2026, the Company entered into a sale‑leaseback arrangement for certain land and warehouse assets which was accounted for as a financing transaction under U.S. GAAP. Accordingly, the proceeds received were recorded as a financing obligation, and the assets will continue to be recognized within “Plants, Properties, and Equipment”. No gain or loss was recognized in connection with the transaction.

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 March 31, 2026, 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”

14

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 three months ended March 31, 2026 and March 31, 2025 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 March 31, 2026, 1,945,447 shares remain available for future grants.

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

	Three Months Ended March 31,
In millions	2026		2025
Total stock-based compensation expense (included in "Selling and administrative expense")	$	3	$	6

As of March 31, 2026, $29 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 1.8 years.

NOTE 15 FINANCIAL INFORMATION BY BUSINESS SEGMENT

The Company’s three 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, the impact of foreign exchange on a note receivable from our Brazilian subsidiary, and net business and 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 is the President and Chief Executive Officer.

Sales by business segment are determined using a management approach and include intersegment sales (which are eliminated in consolidation). External sales in the External Net Sales table are defined as those that are made to parties outside the Company’s combined group.

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, 2025, 2024 and 2023. 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 2025 Form 10-K, particularly under the headings “Risk Factors” and “Forward-Looking Statements.”

EXECUTIVE SUMMARY

First quarter 2026 net loss was $3 million ($0.08 per diluted share) compared with net income of $27 million ($0.65 per diluted share) for the first quarter of 2025. Net sales were $755 million in the current quarter compared with $821 million in the prior year. Cash used for operations was $10 million compared to cash provided by operations of $23 million in the first quarter of last year. Adjusted EBITDA was $29 million and our adjusted EBITDA margin was 4% compared to $90 million and an adjusted EBITDA margin of 11% in the first quarter of 2025. Free cash flow was $(59) million compared to $(25) million in the first quarter of 2025.

2026 is a transition year as we work through some short-term capacity constraints resulting from the termination of the Riverdale supply agreement at the end of April and the extended outage at Eastover later this year as we execute our strategic investments. Comparing our performance in the first quarter of 2026 to the prior year, volume decreased, primarily due to lower North America volume as we build inventory in response to the end of the Riverdale mill supply agreement and the extended Eastover mill outage later in the year. Price and mix decreased primarily in Europe. Operations and costs and input costs were unfavorable. Planned maintenance outage costs were lower as the prior year outage in our Saillat mill did not repeat. We continued to return cash to shareowners through an $18 million dividend payment during the quarter.

Our high-return strategic investments at our Eastover mill are on track and making solid progress. These projects will generate incremental earnings and cash flow over the long term. On May 7, 2026, we completed the refinancing of our accounts receivable securitization facility and Term Loan F to extend our debt maturity profile in order to sustain flexibility and maintain a strong financial position. With a strong financial position we can navigate geopolitical and economic challenges and focus on improving our customer experience, continue reinvesting in low-risk, high-return projects as well as execute through the end of the Riverdale supply and the Eastover mill outage later this year.

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 (loss) 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 (loss) before taxes to business segment operating profit:

	Three Months Ended March 31,
In millions	2026		2025
Income (Loss) Before Income Taxes	$	(6)	$	33
Interest expense, net	9		9

Europe	$	(44)	$	(24)
Latin America	4		26
North America	25		42
Business Segment Operating Profit (Loss) (a)	$	(15)	$	44

(a)    We define business segment operating profit (loss) as our income (loss) before income taxes calculated in accordance with GAAP, excluding net interest expense, the impact of foreign exchange on a note receivable from our Brazilian subsidiary and net special items. We believe that business segment operating profit (loss) 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 charges related to the termination of the Georgetown mill offtake agreement, environmental reserves in Brazil and other charges.

Three Months Ended March 31, 2026 Compared to the Three Months Ended March 31, 2025

The following tables present net sales and operating profit (loss), which is the Company’s measure of business segment profitability, for each of the Company’s segments. See Note 15 Financial Information by Business Segment for more information on the Company’s segments.

Three Months Ended March 31, 2026 Compared to the Three Months Ended March 31, 2025

Our Europe business segment sales were consistent with the same period in 2025, primarily due to lower sales price and mix ($16 million) and lower volumes ($4 million) which were offset by favorable foreign exchange ($20 million).

Europe operating losses were $20 million higher than the same period in 2025, primarily driven by lower sales price and mix ($16 million), lower volumes ($3 million) and higher operating ($9 million) and input costs ($4 million), primarily for energy, which more than offset lower planned maintenance outages ($12 million).

Our Latin America business segment sales decreased $12 million compared to the same period in 2025, primarily driven by lower sales price and mix ($8 million) and lower volumes ($13 million), partially offset by favorable foreign exchange ($9 million).

Operating profit for Latin America was $22 million lower than the same period in 2025, primarily due to lower sales price and mix ($8 million), higher operating costs ($11 million), lower volumes ($3 million) and higher planned maintenance outages ($2 million) which more than offset lower input costs ($2 million), primarily for purchased fiber.

Our North America business segment sales decreased $48 million compared to the same period in 2025, primarily due to lower sales price and mix ($6 million) and lower volumes ($42 million).

Operating profit for North America was $17 million lower than the same period in 2025, primarily due to lower volumes ($12 million), lower sales price and mix ($6 million) and higher input costs ($14 million), primarily due to higher energy, chemicals and distribution costs, which more than offset lower operating costs ($12 million) and lower unabsorbed costs due to economic downtime ($3 million).

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 (loss), 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 March 31,
In millions	2026			2025
Net Income (Loss)	$	(3)		$	27
Income tax provision (benefit)	(3)			6
Interest expense, net	9			9
Depreciation, amortization and cost of timber harvested	41			40
Stock-based compensation	3			6
Foreign exchange gain on intercompany note	(19)			—
Net special items expense (a)	1			2
Adjusted EBITDA (b)	$	29		$	90
Net Sales	$	755		$	821
Adjusted EBITDA Margin	4		%	11		%

(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 charges related to the termination of the Georgetown mill offtake agreement, environmental reserves in Brazil and other charges.

(b)     We define Adjusted EBITDA (non-GAAP) as net income (loss) (GAAP), net of taxes plus the sum of income taxes, net interest expense, depreciation, amortization and cost of timber harvested, stock-based compensation, the impact of foreign exchange on a note receivable from our Brazilian subsidiary, 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 operating activities to free cash flow:

	Three Months Ended March 31,
In millions	2026		2025
Cash provided by (used for) operating activities	$	(10)	$	23
Adjustments:
Cash invested in capital projects	(49)		(48)
Free Cash Flow	$	(59)	$	(25)

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 used for operating activities totaled $10 million for the three months ended March 31, 2026, compared with cash provided by operating activities of $23 million for the three months ended March 31, 2025. The decrease in cash provided by operating activities in 2026 relates primarily to lower net income offset by 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 $28 million for the three months ended March 31, 2026, compared with cash used for working capital components of $50 million for the three months ended March 31, 2025. The three months ended March 31, 2026 working capital components primarily reflect $54 million of cash provided by our accounts and notes receivables, offset by $56 million, $23 million and $3 million of cash used for our inventories, accounts payable and accrued liabilities, and other operating activities, respectively. The three months ended March 31, 2025 working capital components primarily reflect $30 million and $4 million of cash provided by our accounts and notes receivable and inventories, offset by $63 million and $21 million of cash used for our accounts payable and accrued liabilities, and other operating activities, respectively.

Investment Activities

The total cash used for investing activities for the three months ended March 31, 2026 increased from the three months ended March 31, 2025, due to increased capital spending in the current year.

The following table shows capital spending by business segment:

	Three Months Ended March 31,
In millions	2026		2025
Europe	$	5	$	10
Latin America	21		27
North America	23		11
Capital Spending	$	49	$	48

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.

22

Financing Activities

Cash used for financing activities for the three months ended March 31, 2026 primarily reflects the payments of $15 million, $3 million, $3 million, and $25 million on our outstanding principal debt balances for the AR Securitization, Term Loan F-2, Term Loan A, and Revolving Credit Facility, respectively. These amounts are primarily offset by a draw on our AR Securitization and Revolving Credit Facility of $13 million and $90 million, respectively, as well as a receipt of $11 million from other financing arrangements. During the three months ended March 31, 2026 the Company also paid $18 million in dividends and repurchased no shares pursuant to our share repurchase program. Cash used for financing activities for the three months ended March 31, 2025 primarily reflects the payments of $5 million, $3 million, and $3 million on our outstanding principal debt balances for the AR Securitization, Term Loan F-2, and Term Loan A, respectively. These amounts are primarily offset by a draw on our AR Securitization of $22 million. During the three months ended March 31, 2025 the Company also paid $18 million in dividends and repurchased $20 million of our shares pursuant to our share repurchase program.

Contractual Obligations

Our 2025 Form 10-K included disclosures of our contractual obligations and commitments as of December 31, 2025. We continue to make the contractually required payments, and, therefore, the 2025 obligations and commitments described in our 2025 Form 10-K have been reduced by the required payments.

Capital Expenditures

For the three months ended March 31, 2026, we have invested approximately $49 million, or 6.5% of net sales, in total capital expenditures. Over that period, we spent approximately $28 million, or 3.7% of net sales, in maintenance, regulatory and reforestation capital expenditures, and approximately $21 million, or 2.8% 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 $95 million on high-return projects in 2026.

PILLAR TWO DIRECTIVE

The Organization for Economic Co-operation and Development (“OECD”) Pillar Two Model Rules established a minimum global effective tax rate of 15% on country-by-country profits of large multinational companies. European Union member states along with many other countries have adopted or expect to adopt the OECD Pillar Two Model effective January 1, 2024, or thereafter. The OECD and other countries continue to publish guidelines and legislation that include transition and safe harbor rules. We continue to monitor new legislative changes and assess the global impact of the Pillar Two Model Rules. Based on our initial assessment, Pillar Two should not have a material impact to the Company’s income tax provision.

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 2025 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 three months of 2026.

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

23

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: global or regional economic, civil, political conditions or trade developments, including protective trade measures and the Middle East conflict; adverse climate and weather conditions, including risks to our forestlands and mills from drought, fires or floods; 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; disruptions at 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 2025 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 41 of the Company’s 2025 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, 2025.

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 March 31, 2026. 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 first quarter of 2026, 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 2025 Form 10-K. There have been no material changes to the risk factors described in the 2025 Form 10-K. The risk factors in Item 1A. Risk Factors in the 2025 Form 10-K 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.

(a) 114,819 shares were acquired from employees from share withholdings under the Company’s long term incentive compensation program.

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 March 31, 2026, $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 did not repurchase any shares during the three months ended March 31, 2026.

ITEM 5.    OTHER INFORMATION

Accounts Receivable Securitization Program

On May 7, 2026, Sylvamo North America, LLC (the “Subsidiary”), a wholly-owned subsidiary of the Company, and Sylvamo Receivables, LLC (the “Borrower”), a wholly-owned, “bankruptcy remote” special purpose subsidiary of the Subsidiary,

25

entered into Amendment No. 5 (“Amendment No. 5”) to the Receivables Financing Agreement, dated as of September 30, 2022, among the Borrower, the Subsidiary as initial servicer, PNC Bank, National Association (“PNC”), as Administrative Agent, the lenders from time to time party thereto, and PNC Capital Markets LLC as structuring agent. On May 7, 2026, the Subsidiary, Borrower and PNC also entered into Amendment No. 1 to the Purchase and Sale Agreement dated as of September 30, 2022, and the Company entered into an Amended and Restated Performance Guaranty in favor of PNC, to conform such agreements to Amendment No. 5 (collectively, the “Related Amendments”).

Amendment No. 5 and the Related Amendments extend the maturity of the Company’s securitization program from July 30, 2027, to May 7, 2029. The securitization program is an accounts receivable finance facility, pursuant to which the Subsidiary sells to the Borrower, on a continuous revolving basis and without recourse, all U.S. originated trade accounts receivable, together with the rights to collections thereof, related security and certain related rights (including proceeds from qualified insurance providers), unless specifically excluded. Other than the maturity extension, the material terms and conditions of the securitization program remain substantially consistent with those in place prior to Amendment No. 5 and the Related Amendments.

This description does not purport to be complete and is qualified in its entirety by reference to Amendment No. 5, a copy of which is attached hereto as Exhibit 10.6, and the Related Amendments, copies of which are attached hereto as Exhibits 10.7 and 10.8, and incorporated herein by reference.

Farm Credit Term Loans Facility

On May 7, 2026, the Company entered into amendment No. 2 (“Amendment No. 2”) to the Farm Credit Agreement, dated as of July 31, 2024 (the “Farm Credit Agreement”), among the Company, CoBank, ACB, as Administrative Agent, and the lenders from time to time party thereto. Amendment No. 2 created a new Term Loan F-3 Facility with a maturity date of May 7, 2032 (the “Term Loan F-3 Facility”).

The principal amount of the Term Loan F-3 Facility is $357 million. At closing of the Term Loan F-3 Facility on May 7, 2026, the then-existing Term Loan F Facility, which had a maturity date of September 13, 2027 and an outstanding loan amount of $257 million (the “Term Loan F Facility”), was replaced in full by the Term Loan F-3 Facility, effectively extending the maturity date applicable to the $257 million loan. The Company borrowed the remaining $100 million of the Term F-3 Facility to repay a portion of the amount outstanding under the Company’s revolving credit facility.

The Term Loan F-3 Facility initially has an annual rate equal to, at the Company’s option, (i) SOFR plus an applicable margin initially set at 2.05%, or (ii) the base rate plus an applicable margin initially set at 1.05%. At closing, the Company elected option (i). Following the Company’s delivery of financial statements for the quarter ended June 30, 2026, interest rate spreads will be determined by reference to a leveraged-based pricing grid.

The Company is required to make quarterly principal payments under the Term Loan F-3 Facility beginning September 30, 2026 and each subsequent fiscal quarter thereafter, equal to 1.25% of the original principal amount of the $357 million loan (i.e., approximately $4.46 million), with the balance due and payable on the maturity date.

The material terms and conditions of the Farm Credit Agreement, including in respect of guarantees and security, are substantially consistent with those in place prior to Amendment No. 2, but for the terms of the new Term Loan F-3 Facility and the elimination of a 10bps SOFR “credit spread adjustment” applicable to all facilities.

This description does not purport to be complete and is qualified in its entirety by reference to Amendment No. 2, a copy of which is attached hereto as Exhibit 10.9 and incorporated herein by reference.
