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 six 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 six months ended June 30, 2026, with the exception of the below policies that were updated or added.

Revenue Recognition

Generally, the Company recognizes revenue on a point-in-time basis when the Company transfers control of the goods to the customer. Control typically transfers upon shipment or delivery, depending on the applicable shipping terms, at which point the customer obtains legal title and assumes the risks and rewards for the goods. For customized goods where the Company has a legally enforceable right to payment for the goods, the Company recognizes revenue over time, which is as the goods are produced and have no alternative use.

The Company’s revenue is primarily derived from fixed consideration; however, we do have contract terms that give rise to variable consideration, primarily volume rebates, early payment discounts and other customer refunds. The Company estimates its volume rebates at the individual customer level based upon the terms of the arrangement and expected volume purchases over the contract period, consistent with the most likely amount method outlined in ASC 606. The Company estimates early payment discounts and other customer refunds based on the historical experience across the Company’s portfolio of customers to record reductions in revenue which is consistent with the expected value method outlined in ASC 606. Management has concluded that these methods result in the best estimate of the consideration the Company will be entitled to from its customers.

The Company has elected to present all sales taxes on a net basis, account for shipping and handling activities as fulfillment activities, and not record interest income or interest expense when the difference in timing of control or transfer and customer payment is one year or less. See Note 3 Revenue Recognition for further details.

Inventories

Inventories are valued at the lower of cost or market value and include costs directly associated with manufacturing products: materials, labor, first leg freight and manufacturing overhead. In the United States, costs of raw materials and finished paper and pulp products are generally determined using the last-in, first-out method. Other inventories are valued using the first-in, first-out or average cost methods and are held at the lower of cost or net realizable value. See Note 7 Supplementary Financial Statement Information for further details.

Forestlands

The Company owns approximately 250,000 acres of forestlands in Brazil. Forestlands include owned property as well as certain timber harvesting rights with terms of one or more years, and are stated at cost, less cost of timber harvested. Costs related to acquiring and growing timber, including site preparation, seedlings, planting, fertilization, forest management and other direct

5

support costs, are capitalized. Depletion costs attributable to a specific timber plot are recorded within “Cost of timber harvested” as timber is cut. The depletion rates for timber plots are determined annually based on the relationship of incurred costs to estimated recoverable timber volume. See Note 7 Supplementary Financial Statement Information for further details.

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.

NOTE 3 REVENUE RECOGNITION

External Net Sales by Product

Total	$	806	$	794	$	1,561	$	1,615

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 $3 million are included in “Other current liabilities” as of June 30, 2026 and December 31, 2025, respectively.

6

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 June 30,				Six Months Ended June 30,
In millions, except per share amounts	2026		2025		2026		2025
Net income (loss)	$	(11)	$	15	$	(14)	$	42
Weighted average common shares outstanding	39.8		40.6		39.7		40.6
Effect of dilutive securities (a)	—		0.5		—		0.7
Weighted average common shares outstanding - assuming dilution	39.8		41.1		39.7		41.3
Earnings (loss) per share - basic	$	(0.28)	$	0.37	$	(0.35)	$	1.03
Earnings (loss) per share - diluted	$	(0.28)	$	0.37	$	(0.35)	$	1.02
Anti-dilutive shares (b)	0.5		0.2		0.4		0.1

8

(a)    For the three months and six months ended June 30, 2026, 0.2 million and 0.3 million weighted average shares, respectively, 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.

Accounts Payable

The Company maintains supplier finance agreements with third-party financial institutions.

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 $10 million and $3 million as of June 30, 2026 and December 31, 2025, respectively.

As of June 30, 2026 and December 31, 2025, we have recorded liabilities of $29 million and $29 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 8 LEASES

The Company leases various real estate, including certain operating facilities, warehouses, office space and land. The Company also leases material handling equipment, vehicles and certain other equipment. The Company’s leases have remaining lease terms of up to 15 years. Total lease cost was $16 million and $15 million for the three months and $31 million and $30 million for the six months ended June 30, 2026 and 2025, respectively.

NOTE 10 INCOME TAXES

An income tax provision of $12 million and $9 million was recorded for the three and six months ended June 30, 2026, respectively, and the reported effective income tax rate was 1200% and (180)%, respectively. The effective income tax rate for these periods was primarily driven by a $12 million valuation allowance on certain foreign deferred tax assets which are not expected to be realized due to a planned internal merger. An income tax provision of $5 million and $11 million was recorded for the three and six months ended June 30, 2025, respectively, and the reported effective income tax rate was 25% and 21%, respectively.

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 $321 million in interest, penalties and fees as of June 30, 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

11

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 June 30, 2026.

Legacy Basins Environmental Matter (Brazil)

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 was 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, and the Company continued to conduct environmental testing and analysis and engage with CETESB in review of the results and establishing next steps.

On June 15, 2026, an agreement between the Company and CETESB was approved by the State Court of São Paulo, concluding a proceeding initiated by the Company to clarify or close various requirements imposed on the Company by CETESB with respect to the basins’ site (the “CETESB Agreement”). The CETESB agreement is a favorable result for the Company, because it establishes that the type of remediation needed at the site will depend upon the site’s future use to be proposed by the Company. As a result, neither a pilot intervention plan nor further environmental testing to establish a remediation method for the site will be necessary. Pursuant to the CETESB Agreement, by March 2027 (subject to extension), the Company must provide CETESB with a plan for potential future use of the site and proposed monitoring, management and, potentially, remediation, appropriate to such use.

As of June 30, 2026, the Company has recorded an immaterial liability, mainly for fees that it expects to incur for third-party assistance with preparing the Company’s plan contemplated by the CETESB Agreement. The Company is unable to estimate its

12

ultimate potential liability, which may be material and will depend primarily upon the Company’s proposed use for the site in such plan, the monitoring and remediation determined to be appropriate to such use, the timeframe for implementing the plan, and CETESB’s approval of the plan, including any requirements that CETESB may impose as a condition to its approval. CETESB’s approval will depend upon CETESB’s assessment of the plan, including supporting third-party consultant information to be developed and included in the plan.

Suzano Pulp Supply VAT Matter (Brazil)

Suzano S.A. (“Suzano”) and the Company are in arbitration over a dispute related to Suzano’s decision to invoice Brazilian VAT, starting January 2026, on pulp sold to the Company under a supply agreement entered into in 2006 (“Supply Agreement”), pursuant to which Suzano supplies pulp to the Company’s Três Lagoas, Brazil mill. VAT was not invoiced on sales under the agreement prior to 2026, and the parties disagree on whether invoicing VAT is allowed under the Supply Agreement.

In March 2026, the Company obtained a preliminary injunction preventing Suzano from invoicing VAT until resolution of this matter in arbitration. However, on August 6, 2026, Suzano won a court appeal to revoke the injunction, giving Suzano the ability to invoice VAT under the Supply Agreement, potentially totaling $15 to $20 million annually. If the Company prevails in arbitration, the Company will be entitled to recover any VAT amounts collected by Suzano in connection with the Supply Agreement, in addition to any other available remedies. If Suzano were to prevail, its ability to invoice VAT would expire in 2032 due to a change in Brazil’s VAT law.

The dispute process and related arbitration in Brazil is in early stages, and the Company intends to vigorously defend its position that the VAT should not be invoiced. As of June 30, 2026, the Company has not recorded any liability for this matter.

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 $57 million (adjusted for variation in currency exchange rates) regarding unpaid VAT arising from intercompany transactions. This assessment includes $20 million in tax and $37 million in interest and penalties. The Company is challenging this assessment. As of June 30, 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 $19 million which includes $4 million of tax and $15 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 June 30, 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

13

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	June 30, 2026		December 31, 2025
Term Loan F - due 2027 (a)	$	—	$	255
Term Loan F-2 - due 2031 (a)	213		219

Financing Leases	14		16
Other Financing Arrangements	19		—
Less: current portion	(41)		(23)
Total	$	843	$	763

(a) As of June 30, 2026 and December 31, 2025, amounts are presented net of an aggregate total of $3 million and $4 million, respectively, in unamortized debt issuance costs across the 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 June 30, 2026 and December 31, 2025, the Company had $80 million and $67 million of outstanding borrowings on the Revolving Credit Facility, respectively, and an available borrowing capacity of $320 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 2029. 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 June 30, 2026 was 4.65%, and the average interest rate for the year ended December 31, 2025 was 5.28%.

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 were used to repay $100 million of the amount outstanding under the

14

Revolving Credit Facility. The refinancing resulted in debt extinguishment costs of $2 million recorded within "Interest expense, net”.

Interest Rates

The interest rates applicable to the Term Loan F-3, 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 2.05%, 2.15%, 1.85% and 1.85%, respectively, payable monthly, with a SOFR floor of 0.00%. The obligations under the Term Loan F-3, 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-3, Term Loan F-2, and Term Loan F. 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-3 was approximately 4.79% as of June 30, 2026, the effective net interest rate on the Term Loan F-2 was approximately 4.89% and 5.07% as of June 30, 2026 and December 31, 2025, respectively, and the effective net interest rate on the Term Loan F was 4.67% as of December 31, 2025.

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.

			June 30, 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	$	214	$	—	$	—	$	220	$	—	$	3
Term Loan A	4.13% to 4.16%	2028	203		—		1		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. Accordingly, the proceeds received of $11 million were recorded as a financing obligation, and the assets will continue to be recognized within “Plants, properties, and equipment, net”. No gain or loss was recognized in connection with the transaction.

As part of the arrangement, the counterparty will expand the existing warehouse and lease the expanded premises to the Company. Capital expenditures incurred by the counterparty to fund the expansion will be recognized within “Plants, properties and equipment, net” with an offsetting increase to the financing obligation. Non-cash additions to property, plant and equipment and the non-cash increase in long-term debt related to this arrangement were $8 million for the six months ended June 30, 2026.

15

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 June 30, 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” 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 six months ended June 30, 2026 and June 30, 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 June 30, 2026, 1,913,592 shares remain available for future grants.

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

	Three Months Ended June 30,				Six Months Ended June 30,
In millions	2026		2025		2026		2025
Total stock-based compensation expense (included in "Selling and administrative expense")	$	3	$	7	$	6	$	13

As of June 30, 2026, $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 1.6 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. Business Segment Operating Profit (Loss) (non-GAAP) is net income (loss) (GAAP) plus the sum of income taxes, net interest expense, the impact of foreign exchange on an intercompany note receivable from our Brazilian subsidiary, and, when applicable for the periods reported, net special items.

The Company’s chief operating decision maker is the President and Chief Executive Officer. 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.

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

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

Second quarter 2026 net loss was $11 million ($0.28 per diluted share) compared with net income of $15 million ($0.37 per diluted share) for the second quarter of 2025. Net sales were $806 million in the current quarter compared with $794 million in the prior year. Cash provided by operating activities was $38 million compared to $64 million in the second quarter of last year. Adjusted EBITDA was $60 million compared to $82 million in the second quarter of 2025. Free cash flow was $(23) million compared to $(2) million in the second quarter of 2025.

Comparing our performance in the second quarter of 2026 to the prior year, volume decreased, primarily due to lower North America volume with the termination of the Riverdale mill supply agreement and as we build inventory in response to the extended Eastover mill outage later in the year. Price and mix decreased in Europe but were partially offset by improved price and mix in North America. 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 and the current year outage in our Nymölla mill will take place during the fourth quarter. We continued to return cash to shareowners through an $18 million dividend payment during the quarter.

2026 is a transition year as we navigate the termination of the Riverdale supply agreement at the end of April and the extended Eastover outage later this year as we execute our strategic investments. We expect this North America footprint transition to have an unfavorable $85 million impact on full year 2026 Adjusted EBITDA. Our Eastover strategic investments, including our woodyard modernization and paper machine optimization, and new sheeter continue to make good progress. These investments will result in 60,000 additional tons of uncoated freesheet capacity annually, which will start to ramp up early next year. The benefits include reducing costs and improving our mix and efficiency, while enhancing service for our customers. We anticipate an incremental annual benefit of $50 million to Adjusted EBITDA from the paper machine speed-up and the new sheeter, including an estimated $30 million to $40 million benefit in 2027.

This has been a very dynamic year where we continue to adapt to changing conditions while executing the initiatives within our control. We remain focused on generating strong, sustainable results and creating long-term value through disciplined, data-driven decision-making that strengthens Sylvamo for decades to come.

Three Months Ended June 30, 2026 Compared to the Three Months Ended June 30, 2025

Net Sales

Net sales for the three months ended June 30, 2026 increased by $12 million compared to the same period in 2025. The increase was primarily due to favorable foreign exchange impact ($17 million) partially offset by lower sales price and mix ($7 million). Additional information on sales by business segment, excluding inter-segment eliminations, is provided in the section titled Business Segment Results.

Cost of Products Sold

Cost of products sold for the three months ended June 30, 2026 increased by $34 million compared to the same period in 2025. The increase was primarily driven by higher input costs, mainly related to distribution, fiber and energy costs ($23 million), unfavorable foreign exchange, operating and cost impacts ($29 million) and volume impacts ($8 million). These increases were partially offset due to lower planned maintenance outage costs ($25 million) and a favorable impact from foreign exchange on an intercompany note receivable from our Brazilian subsidiary ($1 million).

Selling and Administrative Expenses

Selling and administrative expenses for the three months ended June 30, 2026 decreased by $3 million compared to the same period in 2025. The decrease was primarily due to lower incentive compensation expense partially offset by the net impact of certain special items, including professional and legal fees ($4 million).

Depreciation, Amortization and Cost of Timber Harvested

Depreciation, amortization and cost of timber harvested for the three months ended June 30, 2026 decreased by $2 million compared to the same period in 2025 primarily due to lower timber depletion expense.

Taxes Other Than Payroll and Income Taxes

Taxes other than income taxes of $8 million for the three months ended June 30, 2026 was relatively consistent compared to $7 million in the same period in 2025.

22

Interest Expense, Net

Interest expense, net for the three months ended June 30, 2026 increased by $1 million compared to the same period in 2025. This is primarily due to debt extinguishment costs ($2 million) and higher interest expense which were offset by higher interest income and the capitalization of interest costs for construction projects.

Income Tax Provision

Income tax provision for the three months ended June 30, 2026 increased by $7 million compared to the same period in 2025. This is primarily due to additional tax expense related to a change in valuation allowances for certain foreign deferred tax assets ($12 million) partially offset by lower tax expense resulting from lower pre-tax income.

Six Months Ended June 30, 2026 Compared to the Six Months Ended June 30, 2025

Net Sales

Net sales for the six months ended June 30, 2026 decreased by $54 million compared to the same period in 2025. The change was primarily attributable to lower sales volume ($63 million) and sales price and mix ($37 million) partially offset by favorable foreign exchange impacts ($46 million). Additional information on sales by business segment, excluding inter-segment eliminations, is provided in the section titled Business Segment Results.

Cost of Products Sold

Cost of products sold for the six months ended June 30, 2026 increased by $2 million compared to the same period in 2025. The change was primarily driven by higher input costs ($39 million), mainly related to distribution and energy costs, and unfavorable foreign exchange, operating and cost impacts ($60 million). These increases were largely offset by volume impacts ($39 million), lower planned maintenance outage costs ($35 million), a favorable impact from foreign exchange on an intercompany note receivable from our Brazilian subsidiary ($20 million) and lower unabsorbed costs due to economic downtime ($3 million).

Selling and Administrative Expenses

Selling and administrative expenses for the six months ended June 30, 2026 decreased by $3 million compared to the same period in 2025. The change was primarily the result of lower incentive compensation expense partially offset by the net impact of certain special items, including professional and legal fees ($4 million).

Depreciation, Amortization and Cost of Timber Harvested

Depreciation, amortization and cost of timber harvested for the six months ended June 30, 2026 decreased by $1 million compared to the same period in 2025 primarily due to lower timber depletion.

Taxes Other Than Payroll and Income Taxes

Taxes other than payroll and income taxes for the six months ended June 30, 2026 increased by $5 million compared to the same period in 2025 primarily related to higher energy taxes in Europe.

Interest Expense, Net

Interest expense, net for the six months ended June 30, 2026 increased by $1 million compared to the same period in 2025. This is primarily due to debt extinguishment costs ($2 million) and higher interest expense which were offset by higher interest income and the capitalization of interest costs for construction projects.

Income Taxes

Income tax provision for the six months ended June 30, 2026 decreased by $2 million compared to the same period in 2025. The change is primarily attributable to lower tax expense resulting from lower pre-tax income partially offset by additional tax expense related to a change in valuation allowances for certain foreign deferred tax assets ($12 million).

BUSINESS SEGMENT RESULTS

Reconciliation of Net Income (Loss) to Business Segment Operating Profit

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 net income (loss), the most directly comparable GAAP measure.

OTHER NON-GAAP MEASURES

Reconciliation of Net Income (Loss) to Adjusted EBITDA

Management provides adjusted EBITDA and adjusted EBITDA margin, non-GAAP financial measures, to supplement our GAAP financial information, and they should be considered in addition to, but not instead of, the financial statements prepared in accordance with GAAP. Management uses these measures in managing the operating performance of our business and believes that adjusted EBITDA along with adjusted EBITDA margin provide 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 margin (adjusted EBITDA divided by net sales) is reconciled to net income (loss) margin (net income (loss) divided by net sales), the most directly comparable GAAP measure.

(a)    Adjusted EBITDA (non-GAAP) is net income (loss) (GAAP) 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 an intercompany note receivable from our Brazilian subsidiary, and, when applicable for the periods reported, net special items.

(b) See Note 15 Financial Information by Business Segment for effects of net special items expense (income).

Reconciliation of Cash Provided by Operating Activities to Free Cash Flow

Management provides free cash flow, 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 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. Free cash flow is reconciled to cash provided by operating activities, the most directly comparable GAAP measure.

	Three Months Ended June 30,				Six Months Ended June 30,
In millions	2026		2025		2026		2025
Cash provided by operating activities	$	38	$	64	$	28	$	87
Adjustments:
Cash invested in capital projects	(61)		(66)		(110)		(114)
Free Cash Flow	$	(23)	$	(2)	$	(82)	$	(27)

The non-GAAP financial measures presented in this Form 10-Q (business segment operating profit, adjusted EBITDA, adjusted EBITDA margin and free cash flow) 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

27

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 $28 million for the six months ended June 30, 2026, compared with cash provided by operating activities of $87 million for the six months ended June 30, 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 six months ended June 30, 2026, compared with cash used for working capital components of $48 million for the six months ended June 30, 2025. The six months ended June 30, 2026 working capital components primarily reflect $65 million of cash provided by our accounts and notes receivable, offset by $76 million, $2 million and $15 million of cash used for our inventories, accounts payable and accrued liabilities, and other operating activities, respectively. The six months ended June 30, 2025 working capital components primarily reflect $77 million of cash provided by our accounts and notes receivable, offset by $79 million and $46 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 six months ended June 30, 2026 decreased from the six months ended June 30, 2025, due to decreased capital spending in the current year.

The following table shows capital spending by business segment:

	Six Months Ended June 30,
In millions	2026		2025
Europe	$	8	$	22
Latin America	49		62
North America	53		30
Capital Spending	$	110	$	114

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.

28

Financing Activities

Cash used for financing activities for the six months ended June 30, 2026 primarily reflects the payments of $35 million, $6 million, $6 million, and $165 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 draws on our AR Securitization and Revolving Credit Facility of $25 million and $178 million, respectively, as well as a receipt of $11 million from other financing arrangements. Additionally, a payment of $257 million was made to settle the Term Loan F, which was funded by the issuance of Term Loan F-3 for $357 million. During the six months ended June 30, 2026 the Company also paid $36 million in dividends and repurchased no shares pursuant to our share repurchase program. Cash used for financing activities for the six months ended June 30, 2025 primarily reflects the payments of $27 million, $6 million, and $6 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 draws on our AR Securitization and Revolving Credit Facility of $22 million and $23 million, respectively. During the six months ended June 30, 2025 the Company also paid $36 million in dividends and repurchased $40 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 six months ended June 30, 2026, we have invested approximately $110 million, or 7.0% of net sales, in total capital expenditures. Over that period, we spent approximately $73 million, or 4.7% of net sales, in maintenance, regulatory and reforestation capital expenditures, and approximately $37 million, or 2.4% 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 six 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

29

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: 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 June 30, 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 second 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.

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 June 30, 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 six months ended June 30, 2026.

Organization, Consolidation and Presentation of Financial Statements [Abstract]

BASIS OF PRESENTATION

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 six 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.

Accounting Policies [Abstract]

SIGNIFICANT ACCOUNTING POLICIES

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 six months ended June 30, 2026, with the exception of the below policies that were updated or added.

Revenue Recognition

Generally, the Company recognizes revenue on a point-in-time basis when the Company transfers control of the goods to the customer. Control typically transfers upon shipment or delivery, depending on the applicable shipping terms, at which point the customer obtains legal title and assumes the risks and rewards for the goods. For customized goods where the Company has a legally enforceable right to payment for the goods, the Company recognizes revenue over time, which is as the goods are produced and have no alternative use.

The Company’s revenue is primarily derived from fixed consideration; however, we do have contract terms that give rise to variable consideration, primarily volume rebates, early payment discounts and other customer refunds. The Company estimates its volume rebates at the individual customer level based upon the terms of the arrangement and expected volume purchases over the contract period, consistent with the most likely amount method outlined in ASC 606. The Company estimates early payment discounts and other customer refunds based on the historical experience across the Company’s portfolio of customers to record reductions in revenue which is consistent with the expected value method outlined in ASC 606. Management has concluded that these methods result in the best estimate of the consideration the Company will be entitled to from its customers.

The Company has elected to present all sales taxes on a net basis, account for shipping and handling activities as fulfillment activities, and not record interest income or interest expense when the difference in timing of control or transfer and customer payment is one year or less. See Note 3 Revenue Recognition for further details.

Inventories

Inventories are valued at the lower of cost or market value and include costs directly associated with manufacturing products: materials, labor, first leg freight and manufacturing overhead. In the United States, costs of raw materials and finished paper and pulp products are generally determined using the last-in, first-out method. Other inventories are valued using the first-in, first-out or average cost methods and are held at the lower of cost or net realizable value. See Note 7 Supplementary Financial Statement Information for further details.

Forestlands

The Company owns approximately 250,000 acres of forestlands in Brazil. Forestlands include owned property as well as certain timber harvesting rights with terms of one or more years, and are stated at cost, less cost of timber harvested. Costs related to acquiring and growing timber, including site preparation, seedlings, planting, fertilization, forest management and other direct

support costs, are capitalized. Depletion costs attributable to a specific timber plot are recorded within “Cost of timber harvested” as timber is cut. The depletion rates for timber plots are determined annually based on the relationship of incurred costs to estimated recoverable timber volume. See Note 7 Supplementary Financial Statement Information for further details.

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 $3 million and $3 million are included in “Other current liabilities” as of June 30, 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.

EARNINGS PER SHARE

Earnings Per Share [Abstract]

EARNINGS PER SHARE

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 June 30,				Six Months Ended June 30,
In millions, except per share amounts	2026		2025		2026		2025
Net income (loss)	$	(11)	$	15	$	(14)	$	42
Weighted average common shares outstanding	39.8		40.6		39.7		40.6
Effect of dilutive securities (a)	—		0.5		—		0.7
Weighted average common shares outstanding - assuming dilution	39.8		41.1		39.7		41.3
Earnings (loss) per share - basic	$	(0.28)	$	0.37	$	(0.35)	$	1.03
Earnings (loss) per share - diluted	$	(0.28)	$	0.37	$	(0.35)	$	1.02
Anti-dilutive shares (b)	0.5		0.2		0.4		0.1

(a)    For the three months and six months ended June 30, 2026, 0.2 million and 0.3 million weighted average shares, respectively, 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.

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 $10 million and $3 million as of June 30, 2026 and December 31, 2025, respectively.

INCOME TAXES

INCOME TAXES

An income tax provision of $12 million and $9 million was recorded for the three and six months ended June 30, 2026, respectively, and the reported effective income tax rate was 1200% and (180)%, respectively. The effective income tax rate for these periods was primarily driven by a $12 million valuation allowance on certain foreign deferred tax assets which are not expected to be realized due to a planned internal merger. An income tax provision of $5 million and $11 million was recorded for the three and six months ended June 30, 2025, respectively, and the reported effective income tax rate was 25% and 21%, respectively.

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 $321 million in interest, penalties and fees as of June 30, 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.

COMMITMENTS AND CONTINGENT LIABILITIES

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 June 30, 2026.

Legacy Basins Environmental Matter (Brazil)

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 was 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, and the Company continued to conduct environmental testing and analysis and engage with CETESB in review of the results and establishing next steps.

On June 15, 2026, an agreement between the Company and CETESB was approved by the State Court of São Paulo, concluding a proceeding initiated by the Company to clarify or close various requirements imposed on the Company by CETESB with respect to the basins’ site (the “CETESB Agreement”). The CETESB agreement is a favorable result for the Company, because it establishes that the type of remediation needed at the site will depend upon the site’s future use to be proposed by the Company. As a result, neither a pilot intervention plan nor further environmental testing to establish a remediation method for the site will be necessary. Pursuant to the CETESB Agreement, by March 2027 (subject to extension), the Company must provide CETESB with a plan for potential future use of the site and proposed monitoring, management and, potentially, remediation, appropriate to such use.

As of June 30, 2026, the Company has recorded an immaterial liability, mainly for fees that it expects to incur for third-party assistance with preparing the Company’s plan contemplated by the CETESB Agreement. The Company is unable to estimate its

ultimate potential liability, which may be material and will depend primarily upon the Company’s proposed use for the site in such plan, the monitoring and remediation determined to be appropriate to such use, the timeframe for implementing the plan, and CETESB’s approval of the plan, including any requirements that CETESB may impose as a condition to its approval. CETESB’s approval will depend upon CETESB’s assessment of the plan, including supporting third-party consultant information to be developed and included in the plan.

Suzano Pulp Supply VAT Matter (Brazil)

Suzano S.A. (“Suzano”) and the Company are in arbitration over a dispute related to Suzano’s decision to invoice Brazilian VAT, starting January 2026, on pulp sold to the Company under a supply agreement entered into in 2006 (“Supply Agreement”), pursuant to which Suzano supplies pulp to the Company’s Três Lagoas, Brazil mill. VAT was not invoiced on sales under the agreement prior to 2026, and the parties disagree on whether invoicing VAT is allowed under the Supply Agreement.

In March 2026, the Company obtained a preliminary injunction preventing Suzano from invoicing VAT until resolution of this matter in arbitration. However, on August 6, 2026, Suzano won a court appeal to revoke the injunction, giving Suzano the ability to invoice VAT under the Supply Agreement, potentially totaling $15 to $20 million annually. If the Company prevails in arbitration, the Company will be entitled to recover any VAT amounts collected by Suzano in connection with the Supply Agreement, in addition to any other available remedies. If Suzano were to prevail, its ability to invoice VAT would expire in 2032 due to a change in Brazil’s VAT law.

The dispute process and related arbitration in Brazil is in early stages, and the Company intends to vigorously defend its position that the VAT should not be invoiced. As of June 30, 2026, the Company has not recorded any liability for this matter.

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 $57 million (adjusted for variation in currency exchange rates) regarding unpaid VAT arising from intercompany transactions. This assessment includes $20 million in tax and $37 million in interest and penalties. The Company is challenging this assessment. As of June 30, 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 $19 million which includes $4 million of tax and $15 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 June 30, 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.

Total	$	843	$	763

(a) As of June 30, 2026 and December 31, 2025, amounts are presented net of an aggregate total of $3 million and $4 million, respectively, in unamortized debt issuance costs across the 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 June 30, 2026 and December 31, 2025, the Company had $80 million and $67 million of outstanding borrowings on the Revolving Credit Facility, respectively, and an available borrowing capacity of $320 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 2029. 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 June 30, 2026 was 4.65%, and the average interest rate for the year ended December 31, 2025 was 5.28%.

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 were used to repay $100 million of the amount outstanding under the

Revolving Credit Facility. The refinancing resulted in debt extinguishment costs of $2 million recorded within "Interest expense, net”.

Interest Rates

The interest rates applicable to the Term Loan F-3, 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 2.05%, 2.15%, 1.85% and 1.85%, respectively, payable monthly, with a SOFR floor of 0.00%. The obligations under the Term Loan F-3, 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-3, Term Loan F-2, and Term Loan F. 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-3 was approximately 4.79% as of June 30, 2026, the effective net interest rate on the Term Loan F-2 was approximately 4.89% and 5.07% as of June 30, 2026 and December 31, 2025, respectively, and the effective net interest rate on the Term Loan F was 4.67% as of December 31, 2025.

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.

			June 30, 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	$	214	$	—	$	—	$	220	$	—	$	3
Term Loan A	4.13% to 4.16%	2028	203		—		1		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. Accordingly, the proceeds received of $11 million were recorded as a financing obligation, and the assets will continue to be recognized within “Plants, properties, and equipment, net”. No gain or loss was recognized in connection with the transaction.

As part of the arrangement, the counterparty will expand the existing warehouse and lease the expanded premises to the Company. Capital expenditures incurred by the counterparty to fund the expansion will be recognized within “Plants, properties and equipment, net” with an offsetting increase to the financing obligation. Non-cash additions to property, plant and equipment and the non-cash increase in long-term debt related to this arrangement were $8 million for the six months ended June 30, 2026.

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 June 30, 2026, we were in compliance with our debt covenants.

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 six months ended June 30, 2026 and June 30, 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.

Segment Reporting [Abstract]

FINANCIAL INFORMATION BY BUSINESS SEGMENT AND GEOGRAPHIC AREA

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. Business Segment Operating Profit (Loss) (non-GAAP) is net income (loss) (GAAP) plus the sum of income taxes, net interest expense, the impact of foreign exchange on an intercompany note receivable from our Brazilian subsidiary, and, when applicable for the periods reported, net special items.

The Company’s chief operating decision maker is the President and Chief Executive Officer. 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.

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

Schedule of Interest Rate Derivatives

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.
