INTERNATIONAL PAPER COMPANY

(Unaudited)

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 International Paper Company’s ("International Paper's," "the Company’s," "IP's" or "our") financial position, results of operations, and cash flows for the interim periods presented. Except as disclosed herein, such adjustments are of a normal, recurring nature. Results for the first three months of the year may not necessarily be indicative of full year results. You should read these unaudited condensed financial statements in conjunction with the audited financial statements and the notes thereto included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2024 (the "Annual Report"), which have previously been filed with the U.S. Securities and Exchange Commission ("SEC").

As a result of the completed acquisition of DS Smith Plc, subsequently re-registered as DS Smith Limited ("DS Smith") on January 31, 2025, the Chief Operating Decision Maker ("CODM") now reviews and manages the financial results and operations of the following segments on the basis of the new organizational structure, Packaging Solutions North America, Packaging Solutions Europe, Middle East and Africa ("EMEA") and Global Cellulose Fibers. The Packaging Solutions EMEA segment includes the Company's legacy EMEA Industrial Packaging business and the newly acquired EMEA DS Smith business. As such, amounts related to the Company's legacy EMEA Industrial Packaging business have been recast out of the Industrial Packaging segment into the new Packaging Solutions EMEA segment for all prior periods. The newly acquired North America DS Smith business has been included in the Packaging Solutions North America segment. Amounts related to the Company's legacy North America Industrial Packaging business have been reported in the Packaging Solutions North America segment for all prior periods.

Additionally, certain amounts from prior year in the condensed consolidated balance sheet have been reclassified to conform with the current year financial statement presentation.

These unaudited condensed 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.

Recently Adopted Accounting Pronouncements

Income Taxes

In December 2023, the FASB issued ASU 2023-09, "Income Taxes (Topic 740): Improvements to Income Tax Disclosures." This guidance requires companies to enhance income tax disclosures, particularly around rate reconciliations and income taxes paid information. This guidance is effective for annual reporting periods beginning after December 15, 2024. Early adoption of these amendments is permitted and amendments should be applied prospectively. The Company adopted this guidance as of January 1, 2025 and will update disclosures within the Company's 2025 annual filing.

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)." This guidance requires companies to provide more detailed information of certain income statement expenses within the footnotes to the financial statements. This guidance is effective for annual reporting periods beginning after December 15, 2026 and interim periods within fiscal years beginning after December 15, 2027. Early adoption is permitted. The Company is currently evaluating the provisions of this guidance.

Generally, the Company recognizes revenue on a point-in-time basis when the customer takes title to the goods 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, generally, is as the goods are produced.

Revenue Contract Balances

A contract asset is created when the Company recognizes revenue on its customized products prior to having an unconditional right to payment from the customer, which generally does not occur until title and risk of loss passes to the customer.

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 once control of the goods is transferred to the customer. The majority of our customer prepayments are received during the fourth quarter each year for goods that will be transferred to customers over the following twelve months. Contract liabilities of $33 million and $30 million are included in Other current liabilities in the accompanying condensed consolidated balance sheet as of March 31, 2025 and December 31, 2024, respectively. The Company also recorded a contract liability of $115 million related to a previous acquisition. The balance of this contract liability was $82 million and $84 million at March 31, 2025 and December 31, 2024, respectively, and is recorded in Other current liabilities and Other Liabilities in the accompanying condensed consolidated balance sheet.

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 prepayment from the customer, respectively.

Basic earnings per share is computed by dividing earnings by the weighted average number of common shares outstanding. Diluted earnings per share is computed assuming that all potentially dilutive securities were converted into common shares. There are no adjustments required to be made to net income for purposes of computing basic and diluted earnings per share. A reconciliation of the amounts included in the computation of basic earnings (loss) per share and diluted earnings (loss) per share is as follows:

 

	Three Months Ended March 31,
In millions, except per share amounts	2025		2024
Net earnings (loss)	$	(105)	$	56
Weighted average common shares outstanding	437.6		346.7
Effect of dilutive securities (a)
Restricted performance share plan	—		1.8
Weighted average common shares outstanding – assuming dilution	437.6		348.5
Basic earnings (loss) per share	$	(0.24)	$	0.16
Diluted earnings (loss) per share	$	(0.24)	$	0.16

(a) 6.1 million of securities were anti-dilutive for the three months ended March 31, 2025 and were not included in the table.

During the three months ended March 31, 2025, the Company recorded restructuring charges of $78 million for costs associated with the permanent closure of our Red River containerboard mill in Campti, Louisiana. Included in the $78 million of restructuring charges was $17 million of severance charges recorded in Accrued payroll and benefits in the accompanying condensed consolidated balance sheet, $22 million of inventory charges recorded in Inventories in the accompanying condensed consolidated balance sheet and $39 million of other costs recorded in Other current liabilities and Other Liabilities in the accompanying condensed consolidated balance sheet. The majority of the severance charges will be paid in 2025.

Additionally, during the three months ended March 31, 2025, the Company recorded restructuring charges of $5 million in Accrued payroll and benefits in the accompanying condensed balance sheet for other costs related to our 80/20 strategic approach.

On January 31, 2025, the Company completed its acquisition of the entire issued and to be issued share capital of DS Smith. Upon closing, IP issued 0.1285 shares for each DS Smith share, resulting in the issuance of 178,126,631 new shares of IP common stock ("New Company Common Stock"). As a result of the share issuance, the holders of the New Company Common Stock own approximately 34.1% of the Company's outstanding share capital. Based on the issuance of 178,126,631 new shares and the closing price of $55.63 on the close of January 31, 2025, the total purchase consideration for the completed acquisition was approximately $9.9 billion. Acquisition-related costs were $87 million and $5 million for the three months ended March 31, 2025 and March 31, 2024, respectively, and were recorded in Selling and administrative expenses and Taxes other than payroll and income taxes in the accompanying condensed consolidated statement of operations. On February 4, 2025, the Company began trading the New Company Common Stock and continues to be listed on the New York Stock Exchange under the trading symbol "IP" and via a secondary listing on the London Stock Exchange under the trading symbol "IPC." The headquarters of the combined company is based in Memphis, Tennessee, and the EMEA headquarters has been established at DS Smith's existing main office in London.

The Company is accounting for the acquisition under ASC 805, "Business Combinations" and the results of operations have been included in International Paper's financial statements beginning with the date of acquisition.

The following table summarizes the provisional fair value assigned to assets and liabilities acquired as of January 31, 2025:

In millions
Cash and temporary investments	$	448
Accounts and notes receivable, net	1,386
Inventories	852
Other current assets	147
Plants, properties and equipment	6,429
Intangibles	4,327
Goodwill	4,048
Overfunded pension plan assets	79
Right of use assets	257
Deferred charges and other assets	56
Total assets acquired	18,029
Notes payable and current maturities of long-term debt	60
Accounts payable	1,654
Accrued payroll and benefits	240
Other current liabilities	608
Long-term debt	3,634
Deferred income taxes	1,520
Underfunded pension benefit obligation	78
Long-term lease obligations	177
Other liabilities	149
Total liabilities assumed	8,120
Net assets acquired	$	9,909

The purchase price and related allocation are preliminary and could be revised as a result of adjustments made to the purchase price, additional information obtained regarding assets acquired and liabilities assumed, review of contracts and revisions of provisional estimates of fair values, including, but not limited to, the completion of independent appraisals and valuations related to inventory, property, plant and equipment, acquired intangible assets, leases, taxes, contract assets and derivatives. Adjustments to provisional amounts will be finalized as new information becomes available, but within the adjustment period of up to one year from the acquisition date. Goodwill is not deductible for local income tax purposes and is primarily related to the value of new customers through expansion opportunities not reflected in the fair value of the existing customers relationships and the value of the intellectual property beyond selected life for trade names.

Since the date of acquisition, Net sales of $1.3 billion and Net earnings (loss) of $(107) million have been included in the Company's condensed consolidated statement of operations for the three months ended March 31, 2025.

The identifiable intangible assets acquired in connection with the acquisition of DS Smith included the following:

In millions	Estimated Fair Value		Average Useful Life
Customer relationships and lists	$	3,843	18 years
Tradenames, patents and trademarks, and developed technology	379		15 years
Software (a)	90		3 - 5 years
Other	15		Indefinite lived
Total	$	4,327

(a) Of this balance, $57 million has been placed in service and $33 million is in development.

Below are the consolidated results on an unaudited pro forma basis assuming the acquisition of DS Smith had closed on January 1, 2024:

	Three Months Ended March 31,
In millions	2025 (Unaudited)		2024 (Unaudited)
Net Sales	$	6,636	$	6,726
Net Earnings (Loss)	(107)		11

The unaudited pro forma information for the three months ended March 31, 2025 includes adjustments for additional amortization expense on identifiable intangible assets of $9 million and adjustments for additional depreciation expense on identifiable fixed assets of $6 million and eliminates the write-off of the estimated fair value of inventory of $70 million and the non-recurring integration costs associated with the acquisition of $65 million.

The unaudited pro forma information for the three months ended March 31, 2024 includes adjustments for additional amortization expense on identifiable intangible assets of $27 million, additional depreciation expense on identifiable fixed assets of $19 million, incremental expense of $70 million associated with the write-off of the estimated fair value of inventory and non-recurring integration costs associated with the acquisition of $65 million.

The unaudited pro forma consolidated financial information was prepared for comparative purposes only and includes certain adjustments, as noted above. The adjustments are estimates based on currently available information and actual amounts may have differed materially from these estimates. They do not reflect the effect of costs or synergies that would have been expected to result from the integration of the acquisition. The pro forma information does not purport to represent International Paper's actual results of operation as if the transaction described above would have occurred as of January 1, 2024, nor is it necessarily an indicator of future results.

In connection with the DS Smith acquisition, the European Commission issued its Phase I clearance of the business combination between International Paper and DS Smith on January 31, 2025, with the condition that International Paper commit to divest five European plants in Mortagne, Saint-Amand, and Cabourg (France), Ovar (Portugal) and Bilbao (Spain). The Company agreed to divest these locations and all assets and liabilities at March 31, 2025 related to these locations have been recorded as held for sale in the accompanying condensed consolidated balance sheet. On April 14, 2025, the Company announced it had entered into exclusive negotiations with Palm Group of Germany after receiving an irrevocable offer for the purchase of the European plants. The closing is expected by the end of the second quarter of 2025.

International Paper made income tax payments, net of refunds, of $45 million and $5 million for the three months ended March 31, 2025 and 2024, respectively.

The Company currently estimates that, as a result of ongoing discussions, pending tax settlements and expirations of statutes of limitations, the amount of unrecognized tax benefits could be reduced by approximately $8 million during the next 12 months.

The Organization for Economic Cooperation and Development has proposed a 15% global minimum tax applied on a country-by-country basis (the "Pillar Two rule"), and many countries, including countries in which we operate, have enacted or begun the process of enacting laws adopting the Pillar Two rule. The first component of the Pillar Two rule became effective as of January 1, 2024, and did not have a material impact on the Company’s effective tax rate. With the DS Smith acquisition on January 31, 2025, the evaluation of the impact of the second component of Pillar Two is ongoing but is not expected to have a material impact on the Company's effective tax rate for 2025.

General

The Company is involved in various inquiries, administrative proceedings and litigation relating to environmental and safety matters, personal injury, product liability, labor and employment, contracts, sales of property, intellectual property, tax, and other matters, that arise in the normal course of business. These matters may raise difficult and complicated legal issues and may be subject to many uncertainties and complexities. Moreover, some of these matters allege substantial or indeterminate monetary damages.

International Paper reviews inquiries, administrative proceedings and litigation, including with respect to environmental matters, on an ongoing basis and establishes an estimated liability for specific legal proceedings and other loss contingencies when it determines that the likelihood of an unfavorable outcome is probable, and the amount of the loss can be reasonably estimated. In addition, if the likelihood of an unfavorable outcome with respect to material loss contingencies is reasonably possible and International Paper is able to determine an estimate of the possible loss or range of loss, whether in excess of a related accrued liability of where there is no accrued liability, International Paper will disclose the estimate of the possible loss or range of loss. When no amount in a range of loss is more likely than any other amount in the range, the low end of the range is used as the estimate of the possible loss. International Paper’s assessment of whether a loss is probable is based on management’s assessment of the ultimate outcome of the matter.

Assessments of lawsuits and claims and the estimates reflected herein, are subject to significant judgments about future events, rely heavily on estimates and assumptions, and are otherwise subject to significant known and unknown uncertainties. The matters underlying such estimates may change from time to time and actual losses may vary significantly from current estimates. Additionally, the estimated liability for loss contingencies does not include matters or losses that are not reasonably estimable and probable.

Based on information currently known to International Paper, management believes that loss contingencies arising from pending matters, including the matters described herein, will not have a material adverse effect on the consolidated financial position or liquidity of the Company. However, in light of the inherent uncertainties involved in such 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 materially adverse to the Company's results of operations or cash flows in any particular reporting period.

Environmental

The Company has been named as a potentially responsible party ("PRP") in environmental remediation actions under various U.S.federal and state laws, including the Comprehensive Environmental Response, Compensation and Liability Act of 1980, as amended ("CERCLA"). Many of these proceedings involve the cleanup of hazardous substances at large commercial landfills that received waste from many different sources. While joint and several liability is authorized under CERCLA and equivalent state laws, as a practical matter, liability for CERCLA cleanups is typically allocated among the many PRPs. There are other remediation costs typically associated with the cleanup of hazardous substances at the Company’s current, closed and formerly-owned facilities, and recorded as liabilities in the balance sheet.

Remediation costs are recorded in the consolidated financial statements when they become probable and reasonably estimable. International Paper has estimated the probable liability associated with these environmental remediation matters, including those described herein, to be approximately $284 million and $279 million in the aggregate as of March 31, 2025 and December 31, 2024, respectively.

Cass Lake: One of the matters included above arises out of a closed wood-treatment facility located in Cass Lake, Minnesota. In June 2011, the U.S. Environmental Protection Agency ("EPA") selected and published a proposed soil remedy at the site. In April 2020, the EPA issued a final plan concerning clean-up standards at a portion of the site. The Company is performing RA and continues to cooperate with the EPA on the remaining remediation goals at the site. The estimated liability for the Cass Lake superfund site was $48 million as of both March 31, 2025 and December 31, 2024.

Kalamazoo River: The Company is a PRP with respect to the Allied Paper, Inc./Portage Creek/Kalamazoo River Superfund Site in Michigan. The EPA asserts that the site is contaminated by polychlorinated biphenyls primarily as a result of discharges from various paper mills located along the Kalamazoo River, including a paper mill formerly owned by St. Regis Paper Company ("St. Regis"). The Company is a successor in interest to St. Regis.

•Operable Unit 5, Area 1: In March 2016, the Company received a special notice letter from the EPA (i) inviting participation in implementing a remedy for a portion of the site known as Operable Unit 5 ("OU5"), Area 1, and (ii) demanding reimbursement of EPA past costs totaling $37 million. In December 2016, the EPA issued a unilateral administrative order ("UAO") to the Company and other PRPs to perform the remedy. The Company responded to the UAO, agreeing to comply with the order subject to its sufficient cause defenses. The Company continues to comply with the UAO in performing remediation activities at OU5, Area 1.

•Operable Unit 1 ("OU1"): In October 2016, the Company and another PRP received a special notice letter from the EPA inviting participation in the remedial design ("RD") component of the landfill remedy for the Allied Paper Mill, which is also known as Operable Unit 1. A Record of Decision ("ROD") establishing the final landfill remedy for the Allied Paper Mill was issued by the EPA in September 2016. The Company responded to the Allied Paper Mill special notice letter in December 2016 denying liability for OU1. In 2021, the EPA initiated RA activities. In October 2022, the Company received a unilateral administrative order to perform the RA. The Company began performing the RA in 2023 and established a $27 million reserve to account for this liability in the fourth quarter of 2022. In the fourth quarter of 2024, the Company increased the reserve by $27 million to account for the reasonably estimable costs for the next phases of the RA, following an EPA approved design modification in October to the original remedial design.

The total reserve for the combined liabilities for OU5, Area 1 and OU1 at the Kalamazoo River superfund site was $29 million as of both March 31, 2025 and December 31, 2024.

The Company was named as a defendant by Georgia-Pacific Consumer Products LP, Fort James Corporation and Georgia Pacific LLC (collectively, "GP") in a contribution and cost recovery action for alleged pollution at the site related to the Company's potential CERCLA liability. NCR Corporation and Weyerhaeuser Company were also named as defendants. The lawsuit seeks contribution under CERCLA for costs purportedly expended by plaintiffs ($79 million as of the filing of the complaint) and for future remediation costs. In June 2018, the District Court issued its Final Judgment and Order, which fixed the past cost amount at approximately $50 million (plus interest to be determined) and allocated to the Company a 15% share of responsibility for those past costs. The District Court did not address responsibility for future costs in its decision. In July 2018, the Company and each of the other parties filed notices appealing the Final Judgment and prior orders incorporated into the Final Judgment. In April 2022, the Sixth Circuit Court of Appeals (the "Sixth Circuit") reversed the Final Judgment of the Court, finding that the lawsuit against the Company was time-barred by the applicable statute of limitations. In May 2022, GP filed a petition for rehearing with the Sixth Circuit, which was denied in July 2022. In November 2022, GP filed a petition for writ of certiorari with the U.S. Supreme Court. In October 2023, the U.S. Supreme Court denied GP's writ petition, thus rendering final the Sixth Circuit's decision that GP's lawsuit against the Company was time-barred. In January 2024 GP requested that the District Court’s final order declare that each party is jointly and severally liable for future costs, arguing that the Sixth Circuit decision only applies to past costs. On April 9, 2024, the District Court entered Final Judgment After Remand, declaring, consistent with the Sixth Circuit's decision, that GP’s past costs are time-barred by the applicable statute of limitations. The District Court also entered Final Judgment on Remand that all three parties, including the Company, are jointly and severally liable for future response costs at the site. The Company believes the District Court’s Final Judgment on Remand regarding liability for future costs is in error and has appealed the Final Judgment on Remand on future costs liability to the Sixth Circuit.

Harris County: International Paper and McGinnis Industrial Maintenance Corporation ("MIMC"), a subsidiary of Waste Management, Inc. ("WMI"), are PRPs at the San Jacinto River Waste Pits Superfund Site in Harris County, Texas. The PRPs have been actively participating in the activities at the site and share the costs of these activities.

In October 2017, the EPA issued a ROD selecting the final remedy for the site: removal and relocation of the waste material from both the northern and southern impoundments.

In April 2018, the PRPs entered into an Administrative Order on Consent ("AOC") with the EPA, agreeing to work together to develop the RD for the northern impoundment. The AOC does not include any agreement to perform waste removal or other construction activity at the site.

In 2020, the Company reserved the following estimated liability amounts in relation to remediation at this site: (a) $10 million for the southern impoundment; and (b) $55 million for the northern impoundment, which represented the Company's 50% share of our estimate of the low end of the range of probable remediation costs.

The Company submitted the Final Design Package for the southern impoundment to the EPA, and the EPA approved the plan in May 2021. The EPA issued a Unilateral Administrative Order for RA of the southern impoundment in August 2021. An

16

addendum to the Final 100% RD (Amended April 2021) was submitted to the EPA for the southern impoundment in June 2022. The Company substantially completed the RA for the southern impoundment in 2024.

With respect to the northern impoundment, the PRPs submitted a Final 100% RD to EPA in July 2024. EPA provided comments at the end of October and a Revised Final 100% RD was submitted at the end of November 2024. The total estimated liability for the southern and northern impoundment was $98 million as of both March 31, 2025 and December 31, 2024. The current reserve is primarily for the Company’s 50% share of our estimate of the low end of the range of probable costs to implement the RD. Because of ongoing questions regarding cost effectiveness, timing and gathering other technical data, additional losses in excess of our recorded liability are possible.

Versailles Pond: The Company is a responsible party for the investigation and remediation of Versailles Pond, a 57-acre dammed river impoundment that historically received paperboard mill wastewater in Sprague, Connecticut. A comprehensive investigation has determined that Versailles Pond is contaminated with polychlorinated biphenyls, mercury, and metals. A preliminary remediation plan was prepared in the third quarter of 2023. Negotiations with state and federal governmental officials are ongoing regarding the scope and timing of the remediation. The total estimated liability for Versailles Pond was $29 million and $30 million as of March 31, 2025 and December 31, 2024,

Asbestos-Related Matters

We have been named as a defendant in various asbestos-related personal injury litigation, in both U.S. state and federal court, primarily in relation to the prior operations of certain companies previously acquired by the Company. The Company's total recorded liability with respect to pending and future asbestos-related claims was $100 million net of insurance recoveries as of both March 31, 2025 and December 31, 2024. While it is reasonably possible that the Company may incur losses in excess of its recorded liability with respect to asbestos-related matters, we are unable to estimate any loss or range of loss in excess of such liability, and do not believe additional material losses are probable.

Antitrust

In March 2017, the Italian Competition Authority ("ICA") commenced an investigation into the Italian packaging industry to determine whether producers of corrugated sheets and boxes violated the applicable European competition law. In April 2019, the ICA concluded its investigation and issued initial findings alleging that over 30 producers, including our Italian packaging subsidiary ("IP Italy") and, prior to completion of the business combination certain subsidiaries of DS Smith operating in Italy ("DS Smith Italy"), improperly coordinated the production and sale of corrugated sheets and boxes. In August 2019, the ICA issued its decision and assessed IP Italy a fine of €29 million (approximately $31 million at the then-current exchange rates) for participation in the boxes coordination, which was recorded in the third quarter of 2019. We appealed the ICA decision, and our appeal was denied in May 2021. We further appealed the decision to the Italian Council of State ("Council of State"), and in March 2023 the Council of State largely upheld the ICA’s findings, but referred the calculation of IP Italy’s fine back to the ICA, finding that it was disproportionately high based on the conduct found. Given the failure of the Council of State to address certain arguments brought by IP, we further appealed the Council of State decision to uphold the ICA’s findings. In March 2024, the Council of State published its decision holding that its earlier decision should be interpreted as accepting many of IP Italy’s earlier arguments and that the ICA should reduce IP Italy’s fine accordingly. Notwithstanding these decisions by the Council of State, in March 2024 the ICA served IP Italy with its redetermination decision leaving IP Italy’s fine unchanged. IP appealed the ICA's redetermination decision as inconsistent with the Council of State's 2024 and 2023 decision. In July 2024, the Council of State partially annulled the ICA redetermination decision, reducing IP Italy's fine by $6 million (€6 million). As of March 31, 2025, after giving effect to this development, the Company did not have any remaining liability related to IP Italy's fine. IP Italy has further appealed the Council of State's July 2024 decision seeking further reduction. DS Smith Italy was also subject to the ICA decision but not fined, given its position as leniency applicant. IP Italy, DS Smith Italy, and other producers also have been named in lawsuits, and we have received other claims, by a number of customers for damages associated with the alleged anticompetitive conduct. Given the early stages of these claims and the intention of the Company to defend robustly against such claims, it is too early to predict with any real degree of certainty, the precise overall outcome and ultimate potential liability (if any) that might be incurred in connection therewith, and there can be no guarantee that the aggregate of possible damages against IP Italy and DS Smith Italy could not, together, have a material impact on the Company’s financial condition.

Guarantees

In connection with sales of businesses, property, equipment, forestlands and other assets, International Paper commonly makes representations and warranties relating to such businesses or assets, and may agree to indemnify buyers with respect to tax and environmental liabilities, breaches of representations and warranties, and other matters. Where liabilities for such matters are

17

determined to be probable and reasonably estimable, accrued liabilities are recorded at the time of sale as a cost of the transaction.

Brazil Goodwill Tax Matter: The Brazilian Federal Revenue Service has challenged the deductibility of goodwill amortization generated in a 2007 acquisition by Sylvamo do Brasil Ltda. ("Sylvamo Brazil"), which was a wholly owned subsidiary of the Company until the October 1, 2021 spin-off of the Printing Papers business, after which it became a subsidiary of Sylvamo Corporation ("Sylvamo"). Sylvamo Brazil received assessments for the tax years 2007-2015 totaling approximately $103 million (adjusted for variation in currency exchange rates) in tax, plus interest, penalties and fees. The interest, penalties and fees currently total approximately $260 million (adjusted for variation in currency exchange rates). Accordingly, the assessments currently total approximately $363 million (adjusted for variation in currency exchange rates). After an initial favorable ruling challenging the basis for these assessments, Sylvamo Brazil received subsequent unfavorable decisions from the Brazilian Administrative Council of Tax Appeals. Sylvamo Brazil appealed these decisions. On October 11, 2024, the federal regional court issued a ruling favorable to Sylvamo Brazil in the first stage of judicial review on the assessments for tax years 2007 and 2008-2012, comprising approximately $230 million of the total $363 million as of March 31, 2025. On December 18, 2024, the Brazilian Federal Revenue Service appealed this ruling. This tax litigation matter may take many years to resolve. Sylvamo Brazil and International Paper believe the transaction underlying these assessments was appropriately evaluated, and that Sylvamo Brazil's tax position should be sustained, based on Brazilian tax law.

This matter pertains to a business that was conveyed to Sylvamo on October 1, 2021, as part of our spin-off transaction. Pursuant to the terms of the tax matters agreement entered into between the Company and Sylvamo, the Company will pay 60% and Sylvamo will pay 40%, on up to $300 million of any assessment related to this matter, and the Company will pay all amounts of the assessment over $300 million. Under the terms of the tax matters agreement, decisions concerning the conduct of the litigation related to this matter, including strategy, settlement, pursuit and abandonment, will be made by the Company. Sylvamo thus has no control over any decision related to this ongoing litigation. The Company intends to vigorously defend this historical tax position against the current assessments and any similar assessments that may be issued for tax years subsequent to 2015. The Brazilian government may enact a tax amnesty program that would allow Sylvamo Brazil to resolve this dispute for less than the assessed amount. As of October 1, 2021, in connection with the recording of the distribution of assets and liabilities resulting from the spin-off transaction, the Company established a liability representing the initial fair value of the contingent liability under the tax matters agreement. The contingent liability was determined in accordance with ASC 460 "Guarantees" based on the probability weighting of various possible outcomes. The initial fair value estimate and recorded liability as of December 31, 2021 was $48 million and remains this amount at March 31, 2025. This liability will not be increased in subsequent periods unless facts and circumstances change such that an amount greater than the initial recognized liability becomes probable and estimable.

Variable Interest Entities

As of March 31, 2025, the fair value of the Timber Notes and Extension Loans for the 2007 Financing Entities was $2.4 billion and $2.1 billion, respectively. The Timber Notes and Extension Loans are classified as Level 2 within the fair value hierarchy, which is further defined in Note 1 in the Company’s Annual Report.

The Timber Notes of $2.3 billion and the Extension Loans of $2.1 billion both mature in 2027 and are shown in Long-term nonrecourse financial assets of variable interest entities and Long-term nonrecourse financial liabilities of variable interest entities, respectively, on the accompanying condensed consolidated balance sheet.

Activity between the Company and the 2007 Financing Entities was as follows:

	Three Months Ended March 31,
In millions	2025		2024
Revenue (a)	$	33	$	39
Expense (b)	29		35
Cash receipts (c)	30		34
Cash payments (d)	30		34

(a)The revenue is included in interest expense, net in the accompanying statement of operations and includes approximately $5 million for both the three months ended March 31, 2025 and 2024 of accretion income for the amortization of the basis difference adjustment on the Long-term financial assets of variable interest entities.

18

(b)The expense is included in interest expense, net in the accompanying statement of operations and includes approximately $2 million for both the three months ended March 31, 2025 and 2024 of accretion expense for the amortization of the basis difference adjustment on the Long-term nonrecourse financial liabilities of variable interest entities.

(c)The cash receipts are interest received on the Long-term financial assets of variable interest entities.

(d)The cash payments are interest paid on Long-term nonrecourse financial liabilities of variable interest entities.

The borrowing capacity of the Company's commercial paper program is $1.0 billion supported by its $1.4 billion credit agreement. Under the terms of the program, individual maturities on borrowings may vary, but not exceed one year from the date of issue. Interest bearing notes may be issued either as fixed or floating rate notes. During the first quarter of 2025, the Company borrowed, and had outstanding, $175 million under the program.

At March 31, 2025, International Paper’s USD denominated credit facilities totaled $1.9 billion. The credit facilities generally provide for interest rates at a floating rate index plus a pre-determined margin dependent upon International Paper’s credit rating. The credit facilities included a $1.4 billion contractually committed bank facility with a maturity date of June 2028. The liquidity facilities also include up to $500 million of uncommitted financings based on eligible receivables balances under a receivables securitization program that expires in June 2025. At March 31, 2025, the Company had no borrowings outstanding under the receivables securitization program.

Following the DS Smith acquisition, International Paper assumed foreign denominated debt in various currencies with an approximated value of $3.6 billion. The assumed foreign credit facilities include a £1.25 billion contractually committed bank facility, a €200 million credit facility, a €60 million committed credit facility and a £50 million uncommited bank facility. The £1.25 billion contractually committed credit facility has a May 2027 maturity date. In March 2025, the Company amended and restated its credit facility agreement to, among other things (i) replace its obligation to prepare audited and unaudited consolidated accounts and instead provide International Paper’s account information, on the same terms as International Paper’s existing credit facilities, (ii) amend the financial covenant in the credit facility agreement to align with financial covenants given by International Paper in its existing credit facilities, (iii) amend certain events of default, and undertakings to align more closely with certain equivalent provisions included in the documentation relating to the existing financings of International Paper and to allow additional flexibility for potential reorganization of DS Smith’s subsidiaries, if required, now that DS Smith and its subsidiaries are part of the International Paper group. The multi-currency credit facility allows for GBP, EUR and USD borrowings and provides for interest rates at a floating rate index plus a pre-determined margin. Credit facility borrowings are denominated in the currency that aligns with the Company's cashflows. At March 31, 2025, the Company had $909 million outstanding under this facility.

At March 31, 2025, the Company had €200 million borrowings outstanding under the €200 million credit facility agreement with maturity dates from June 2025 through March 2029. In April 2025, the Company amended and restated this credit facility agreement to, among other things (i) replace its obligation to prepare audited and unaudited consolidated accounts and instead provide International Paper’s account information, on the same terms as International Paper’s existing credit facilities, (ii) amend the financial covenant in the credit facility agreement to align with financial covenants given by International Paper in its existing credit facilities, (iii) amend certain events of default, and undertakings to align more closely with certain equivalent provisions included in the documentation relating to the existing financings of International Paper and to allow additional flexibility for potential reorganization of DS Smith’s subsidiaries, if required, now that DS Smith and its subsidiaries are part of the International Paper group. The credit facility agreement provides for interest rates at a fixed rate. The Company’s credit facility agreement is not subject to any restrictive covenants other than that International Paper must comply with the same negative covenants as per its existing credit facilities.

The Company's €60 million committed bank facility matures in December 2026. In April 2025, the Company amended and restated this credit facility agreement to, among other things (i) replace its obligation to prepare audited and unaudited consolidated accounts and instead provide International Paper’s account information, on the same terms as International Paper’s existing credit facilities, (ii) amend the financial covenant in the credit facility agreement to align with financial covenants given by International Paper in its existing credit facilities, (iii) amend certain events of default, and undertakings to align more closely with certain equivalent provisions included in the documentation relating to the existing financings of International Paper and to allow additional flexibility for potential reorganization of DS Smith’s subsidiaries, if required, now that DS Smith and its subsidiaries are part of the International Paper group. The multi-currency credit facility allows for GBP, EUR and USD borrowings. At March 31, 2025, there were no borrowings outstanding under this agreement.

The Company has a £50 million uncommitted bank facility. At March 31, 2025 the Company had $63 million of translated borrowings outstanding under this agreement with no capacity remaining.

19

During the first quarter of 2025, the Company borrowed a USD equivalent $64 million under these foreign denominated credit facilities.

In the first quarter of 2025, International Paper entered into agreements to guarantee the outstanding notes of DS Smith. This included €600 million 0.8750% Notes due September 12, 2026; €850 million 4.375% Notes due July 27, 2027; £250 million 2.875% Notes due July 26, 2029; and €650 million 4.500% Notes due July 27, 2030.

At March 31, 2025, contractual obligations for future payments of debt maturities (including finance lease liabilities disclosed in Note 10 - Leases and excluding the timber monetization structure disclosed in Note 14 - Variable Interest Entities) by calendar year were as follows: $428 million in 2025; $905 million in 2026; $2.3 billion in 2027; $717 million in 2028; $344 million in 2029 and $4.9 billion thereafter.

The Company’s financial covenants require the maintenance of a minimum net worth, as defined in our debt agreements, of $9 billion and a total debt-to-capital ratio of less than 60%. Net worth is defined as the sum of common stock, paid-in capital and retained earnings, less treasury stock plus any cumulative goodwill impairment charges. The calculation also excludes accumulated other comprehensive income/loss and both the current and long-term Nonrecourse Financial Liabilities of Variable Interest Entities. The total debt-to-capital ratio is defined as total debt divided by the sum of total debt plus net worth. As of March 31, 2025, we were in compliance with our debt covenants.

At March 31, 2025, the fair value of International Paper’s $9.6 billion of debt was approximately $9.3 billion. The fair value of the Company’s long-term debt is estimated based on the quoted market prices for the same or similar issues. International Paper’s long-term debt is classified as Level 2 within the fair value hierarchy, which is further defined in Note 1 in the Company’s Annual Report.

NOTE 16 - DERIVATIVES AND HEDGING ACTIVITIES

As a multinational company, International Paper is exposed to market risks, such as changes in interest rates, currency exchange rates and commodity prices.

International Paper periodically uses derivatives and other financial instruments to hedge exposures to interest rate, commodity and currency risks. International Paper does not hold or issue financial instruments for trading purposes. For hedges that meet the hedge accounting criteria at inception, International Paper formally designates and documents the instrument as a fair value hedge, a cash flow hedge or a net investment hedge of a specific underlying exposure.

Derivative and Hedging Accounting Policy

The Company and its subsidiaries are exposed to certain risks relating to its ongoing financial arrangements. The Company uses derivative financial instruments, primarily commodity swaps and forward contracts, to manage currency and commodity risks associated with the Company’s underlying business activities and the financing of these activities. As a matter of policy, we do not use financial instruments for speculative purposes.

ASC 815 requires entities to recognize all derivative instruments as either assets or liabilities in the statement of financial position at fair value. The accounting for changes in the fair value (i.e., gains or losses) of a derivative instrument depends on whether it has been designated and qualifies as part of a hedge accounting relationship and, further, on the type of hedge accounting relationship.

For those derivative or nonderivative instruments that are designated and qualify as hedging instruments under ASC 815, a company must designate the hedging instrument, based upon the exposure being hedged, as a fair value hedge, cash flow hedge, or a net investment hedge.

Gains or losses on cash flow hedges are deferred as a component of AOCI or losses and are reclassified into earnings at the time the hedged item affects earnings, presented in the same income statement line item as the underlying hedged item (i.e., in “cost of products sold” when the hedged transactions are commodity cash flows associated with energy purchases to facilitate operations). If it becomes probable that a forecasted transaction will not occur, previously deferred gains and losses related to those forecasted transactions would be recognized in earnings in the current period.

Gains and losses on net investment hedges are recorded in the cumulative translation adjustment component of AOCI, offsetting the translation adjustment of the net investment being hedged. Any deferred gains or losses previously recorded in the cumulative translation adjustment component of AOCI will remain in AOCI until the hedged net investment is sold or

20

substantially liquidated, at which time the cumulative deferred gains or losses are reclassified into earnings as a component of gain or loss on the sale of the hedged net investment.

To qualify for hedge accounting, a specified level of hedge effectiveness between the hedging instrument and the item being hedged must be achieved at inception and maintained throughout the hedged period. We formally document our risk management objectives, our strategies for undertaking the hedge transactions, the nature of and relationships between the hedging instruments and hedged items, and the method for assessing hedge effectiveness. Additionally, for qualified hedges of forecasted transactions, we specifically identify the significant characteristics and expected terms of the forecasted transactions.

Our designated derivative contracts include commodity swap contracts and forward contracts. Commodity swap contracts effectively modify the Company’s exposure to changes in natural gas and electricity prices by allowing the Company to purchase energy on a fixed-rate basis. Forward contracts effectively modify the Company’s exposure to fluctuations in the cost of carbon credits by allowing the Company to purchase carbon credits on a fixed-rate basis. These agreements involve the receipt of floating-rate amounts in exchange for fixed-rate amounts over the life of the agreements.

Commodity Risk Management

The Company has entered into commodity swap and commodity forward contracts which have been designated as cash flow hedges of commodity price risk associated with forecasted purchases and sales of various commodities used in the Company’s operations. These commodity contracts are used to manage exposure to changes in natural gas, electricity, and carbon credit prices. Individual commodity contracts are entered into up to three years prior to the occurrence of the hedged transactions.

Foreign Currency Risk Management

The Company and its subsidiaries periodically use non-derivative, foreign currency denominated loans to hedge the Company’s foreign currency exposure related to the translation of its net investment in foreign subsidiaries. Certain of these loans are designated as net investment hedges.

The component of the gains and losses on our net investment in these designated foreign operations, driven by changes in foreign exchange rates, are economically offset by remeasurements of our foreign-currency denominated debt.

The notional amounts of financial instruments used in hedging transactions were as follows:

In millions	March 31, 2025		December 31, 2024
Derivatives in Cash Flow Hedging Relationships:
Electricity contract (MWh)	0.7		—
Natural gas contracts (MWh)	6.2		—
Carbon credit contracts (tons)	0.7		—
Derivatives in Net Investment Hedging Relationships:
External debt (EUR)	€	3,198	€	—
Derivatives Not Designated as Hedging Instruments:
Electricity contract (MWh)	0.2		0.3

The following table shows gains or losses recognized in AOCI, net of tax, related to derivative instruments:

Derivatives in Cash Flow Hedging Relationships:
Commodity contacts	$	(52)	$	—
Derivatives in Net Investment Hedging Relationships:

Based on our valuation at March 31, 2025, and assuming market rates remain constant through contract maturities, we expect transfers to earnings of the existing gain or losses reported in AOCI on cash flow hedges during the next 12 months to correspond with the current assets and liabilities portion of the derivative as disclosed below.

Fair Value Measurements

The Company has not changed its valuation techniques for measuring the fair value of any financial assets or liabilities during the year. Transfers between levels, if any, are recognized at the end of the reporting period. International Paper’s derivatives are classified as Level 2 within the fair value hierarchy. Fair value hierarchies are further defined in Note 1 in the Company’s Annual Report.

The following table provides a summary of the impact of our derivative instruments in the balance sheet:

 

	Assets						Liabilities

(b)Includes $3 million recorded in Other current assets in the accompanying condensed consolidated balance sheet.

(c)Includes $64 million recorded in Other current liabilities and $16 million recorded in Other liabilities in the accompanying condensed consolidated balance sheet.

The above contracts are subject to enforceable master netting arrangements that provide rights of offset with each counterparty when amounts are payable on the same date in the same currency or in the case of certain specified defaults. Management has made an accounting policy election to not offset the fair value of recognized derivative assets and derivative liabilities in the balance sheet. The amounts owed to the counterparties and owed to the Company are considered immaterial with respect to each counterparty and in the aggregate with all counterparties.

International Paper operates both defined benefit and defined contribution pension plans as well as other post retirement benefit plans throughout our operations in accordance with local conditions and practice.

We sponsor and maintain the Retirement Plan of International Paper Company (the "Pension Plan"), a tax-qualified defined benefit pension plan that provides retirement benefits to substantially all hourly and union employees who work at a participating business unit. The Pension Plan was frozen as of January 1, 2019 for salaried participants.

The Pension Plan provides defined pension benefits based on years of credited service and either final average earnings (salaried employees and hourly employees receiving salaried benefits), hourly job rates or specified benefit rates (hourly and union employees).

In connection with our acquisition, International Paper acquired the existing DS Smith Group Pension plan (the "Group Plan"), a UK funded defined benefit plan providing pension benefits and lump sum benefits to members and dependents. The Group Plan closed to new entrants and future accruals as of April 30, 2011.

Net periodic pension expense (income) for our qualified and nonqualified defined benefit plans and the Group Plan, comprised the following: 

	Three Months Ended March 31,
In millions	2025		2024
Service cost	$	10	$	13
Interest cost	124		111
Expected return on plan assets	(151)		(148)
Actuarial loss	18		19
Amortization of prior service cost	4		3
Settlement	8		—
Net periodic pension expense (income)	$	13	$	(2)

The components of net periodic pension expense (income) other than the Service cost component are included in Non-operating pension expense (income) in the condensed consolidated statement of operations.

The Company’s funding policy for our 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 plan, tax deductibility, the cash flows generated by the Company, and other factors. The Company made no voluntary cash contributions to the qualified pension plan in the first three months of 2025 or 2024. The nonqualified defined benefit plans are funded to the extent of benefit payments, which totaled $33 million and $5 million for the three months ended March 31, 2025 and 2024, respectively.

International Paper's 2024 Long-term Incentive Compensation Plan (the "2024 LTICP') authorizes grants of restricted stock, restricted or deferred stock units, performance awards payable in cash or stock upon the attainment of specified performance goals, dividend equivalents, options, stock appreciation rights, other stock-based awards and cash-based awards at the discretion of the Management Development and Compensation Committee of the Board of Directors (the “MDCC”). On December 9, 2024, the MDCC approved the 2025 Long-Term Incentive Plan (the "2025 LTIP"), pursuant to the 2024 LTICP, approving a sole performance metric of 100% relative total shareholder return ("TSR") for performance stock unit awards, effective January 1, 2025. As of March 31, 2025, 7.0 million shares were available for grant under the LTICP.

Subsequent to the acquisition of DS Smith, the Company agreed to provide equity transition awards to DS Smith employees who became employees of the Company after closing of the transaction. The transition awards, which were granted in March 2025, consisted of time-based restricted stock units. The transition awards replaced the unvested portion of the 2024 DS Smith Performance Share Plan award granted to DS Smith employees in July 2024.

Stock-based compensation expense and related income tax benefits were as follows:

	Three Months Ended March 31,
In millions	2025		2024
Total stock-based compensation expense (selling and administrative)	$	32	$	9
Income tax benefits related to stock-based compensation	38		13

At March 31, 2025, $150 million, net of estimated forfeitures, of compensation cost related to time-based and performance-based shares and restricted stock attributable to future service had not yet been recognized. This amount will be recognized in expense over a weighted-average period of 1.9 years.

During the first three months of 2025, the Company granted 1.0 million performance units at an average grant date fair value of $66.30 and 0.9 million time-based units at an average grant date fair value of $54.17.

As a result of the completed acquisition of DS Smith on January 31, 2025, the CODM now reviews and manages the financial results and operations of the following segments on the basis of the new organizational structure, Packaging Solutions North America, Packaging Solutions EMEA and Global Cellulose Fibers. The Packaging Solutions EMEA segment includes the Company's legacy EMEA Industrial Packaging business and the newly acquired EMEA DS Smith business. As such, amounts related to the Company's legacy EMEA Industrial Packaging business have been recast out of the Industrial Packaging segment into the new Packaging Solutions EMEA segment for all prior periods. The newly acquired North America DS Smith business has been included in the Packaging Solutions North America segment. Amounts related to the Company's legacy North America Industrial Packaging business have been reported in the Packaging Solutions North America segment for all prior periods.

Packaging Solutions North America and Packaging Solutions EMEA are primarily focused on producing fiber-based packaging. We produce linerboard, medium, whitetop, recycled linerboard, recycled medium and saturating kraft of which a majority of our production is converted into corrugated packaging and other packaging. The revenue for our Packaging Solutions North America and Packaging Solutions EMEA segments are derived from selling these products to our customers.

Global Cellulose Fibers primarily focuses on producing cellulose fibers which is a renewable raw material used in a variety of products people depend on every day such as diapers, towel and tissue products, feminine care, incontinence and other personal care products. In addition, our innovative specialty pulps serve as a sustainable raw material used in textiles, construction materials, paints, coatings and more. The revenue for our Global Cellulose Fibers segment is derived from selling these products to our customers.

The CODM assesses performance for these segments and decides how to allocate resources based on business segment operating profit. Business segment operating profits (losses) are also used by International Paper's CODM to measure the earnings performance of its businesses and to focus on on-going operations.

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

The following discussion and analysis of our financial condition and results of operations should be read in conjunction with our unaudited condensed consolidated financial statements and related notes included in "Financial Statements and Supplementary Data" of this Quarterly Report on Form 10-Q (this "Form 10-Q") and the Company's Annual Report on Form 10-K for the year ended December 31, 2024 (our "Annual Report"). 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 discussed in the forward-looking statements. Factors that could cause or contribute to those differences include those discussed below and in our Annual Report, particularly under "Risk Factors" and "Forward-Looking Statements" of this Form 10-Q and our Annual Report. Please see our "Cautionary Statement Regarding Forward-Looking Statements" below.

EXECUTIVE SUMMARY

Net earnings (loss) were $(105) million ($(0.24) per diluted share) in the first quarter of 2025, compared with $(147) million ($(0.42) per diluted share) in the fourth quarter of 2024 and $56 million ($0.16 per diluted share) in the first quarter of 2024. The Company generated Adjusted operating earnings (a non-GAAP measure defined below) of $101 million ($0.23 per diluted share) in the first quarter of 2025, compared with $(7) million ($(0.02) per diluted share) in the fourth quarter of 2024 and $61 million ($0.17 per diluted share) in the first quarter of 2024.

International Papers’ first quarter results reflect higher sales and earnings through the successful execution of sale price increases, benefits from transformation initiatives and some favorable non-recurring items. Our results also reflect two months of sales and earnings from the DS Smith acquisition completed on January 31, 2025. As a result of our commercial strategy, we believe we have made progress growing our position in our Packaging Solutions North America business, while executing price increases. We saw a shift in the demand environment during the first quarter of 2025 across the end markets we serve, which we believe is due to increased uncertainty related to potential tariff implications. Industry demand in North America was down in the first quarter of 2025 on a year-over-year basis and we expect that trend to continue into the second quarter of 2025. Demand across the European markets remained soft, but stable. Despite uncertainty in the macroeconomic landscape, we have several initiatives underway and solid momentum that we believe will help drive earnings improvement over the remainder of this year. We are taking actions designed to drive out cost, to increase productivity and efficiencies and to improve our commercial performance.

Comparing the first quarter of 2025 financial performance to the fourth quarter of 2024, for the legacy International Paper business, sales were relatively flat on seasonally lower volumes. This was offset by slightly higher price and mix in our Packaging Solutions North America business, driven by the flow through of prior price index movements. First quarter of 2025 cost of goods sold was lower on improved operations and costs due to better mill and box plant performance, cost reduction initiatives, along with favorable non-recurring items, which include employee benefit costs, insurance proceeds from the Ixtac, Mexico box plant fire and lower incentive compensation cost. Maintenance outage expense was sequentially flat while input costs were slightly higher due to increased energy costs early in the first quarter of 2025, partially offset by lower fiber costs. First quarter of 2025 results reflect the favorable impact of a lower tax rate versus the prior quarter as a result of favorable discrete items. Accelerated depreciation recognized in the first quarter of 2025 associated with the announced closure of the Campti, Louisiana mill largely offset the non-repeat of accelerated depreciation expense recognized in the fourth quarter of 2024 associated with the Georgetown, South Carolina mill closure and some box plant closures. Finally, first quarter sales and operating earnings reflect two months of DS Smith activity following the January 31, 2025 acquisition. This includes the impact of higher depreciation and amortization resulting from the stepped-up property, plant and equipment and intangible assets associated with the DS Smith purchase accounting.

The following is a discussion, by segment, of first quarter of 2025 performance versus the fourth quarter of 2024 as well as the second quarter of 2025 outlook. First quarter of 2025 operating profit in our Packaging Solutions North America business was $142 million versus $228 million in the fourth quarter of 2024. This includes an operating loss of $9 million for the DS Smith North America business for the two months following the acquisition. Price and mix was higher from the realization of index movement and open market sales. We expect continued price realization in the second quarter of 2025 due to the prior index movement. Volume was seasonally lower in the first quarter of 2025, but we expect improvements in the second quarter of 2025 as we enter the heavy agriculture season along with anticipated continued progress in growing our position as a result of our commercial strategy. Operations and costs in the first quarter of 2025 was sequentially lower due to our cost out initiatives, along with lower costs associated with employee incentive compensation and favorable medical benefits. We also received $30 million of insurance recoveries related to the 2024 fire at our Ixtac, Mexico facility. Operations and costs are expected to be higher in the second quarter of 2025 as the favorable items from the first quarter of 2025 are not expected to repeat along with

27

additional maintenance costs due to timing. Planned maintenance outage costs were sequentially flat in the first quarter of 2025 but the second quarter is expected to be a heavier maintenance outage quarter. Depreciation and amortization was $208 million higher in the first quarter of 2025 primarily due to the closure of the Campti, Louisiana mill. The second quarter of 2025 will reflect the non-repeat of accelerated depreciation.

First quarter 2025 operating profit in our Packaging Solutions EMEA business was $46 million versus $19 million in the fourth quarter of 2024. This includes an operating profit of $13 million for the DS Smith EMEA business for the two months following the acquisition. Price and mix was sequentially lower in the first quarter of 2025 due to the impact of price decreases. We expect price and mix to be flat in the second quarter of 2025. Volume was sequentially flat in the first quarter of 2025, and we expect the second quarter of 2025 to remain flat relative to the first quarter of 2025. Operations and costs in the first quarter of 2025 was sequentially lower driven by lower employee incentive compensation and favorable medical benefit costs. Additionally, operations and costs benefited from energy credits on efficiency projects in the business. Operations and costs are expected to be higher in the second quarter of 2025 as these credits are not expected to repeat. Planned maintenance outage costs were slightly lower in the first quarter of 2025 versus the fourth quarter of 2024. The second quarter of 2025 is expected to be marginally higher than the first quarter of 2025.

First quarter of 2025 operating profit in our Global Cellulose Fibers business was $17 million versus a $250 million operating loss in the fourth quarter of 2024. Price and mix was higher versus the fourth quarter of 2024 on improved fluff mix and the sale of energy credits. We expect price and mix to be higher in the second quarter of 2025 on continued price realization from prior index movement. Volume was sequentially flat in the first quarter of 2025, and we expect the second quarter of 2025 to remain flat relative to the first quarter of 2025. Operations and costs were sequentially lower in the first quarter of 2025 due to improved mill performance and lower costs associated with employee incentive compensation. We expect second quarter of 2025 operations and costs to be flat compared to the first quarter of 2025. Planned maintenance outage costs were sequentially higher in the first quarter of 2025. Second quarter of 2025 is expected to be higher as one maintenance outage was moved to the second quarter which will drive higher costs relative to the first quarter of 2025. Finally, first quarter of 2025 depreciation and amortization was lower on the non-repeat of accelerated depreciation expense associated with the Georgetown, South Carolina mill closure in the fourth quarter of 2024.

Acquisition of DS Smith

On January 31, 2025, the Company completed its acquisition of the entire issued and to be issued share capital of DS Smith. Upon closing, IP issued 0.1285 shares for each DS Smith share, resulting in the issuance of 178,126,631 new shares of IP common stock (“New Company Common Stock”). As a result of the share issuance, the holders of the New Company Common Stock owned approximately 34.1% of the Company’s outstanding share capital upon closing. Based on the issuance of 178,126,631 new shares and the closing price of $55.63 on the close of January 31, 2025, the total purchase consideration for the completed acquisition was approximately $9.9 billion.

On February 4, 2025, the shares of New Company Common Stock began trading on the New York Stock Exchange under the symbol “IP” and the shares of Company Common Stock, including the shares of New Company Common Stock, began trading on the London Stock Exchange via a secondary listing under the symbol “IPC.” The headquarters of the combined company is based in Memphis, Tennessee, and the EMEA headquarters has been established at DS Smith’s existing main office in London.

Divestiture of European Corrugated Box Plants

On April 14, 2025, the Company announced it entered into exclusive negotiations with Palm Group of Germany after receiving an irrevocable offer for the purchase of five plants in Europe: (i) three plants in Normandy, France (namely, one box plant in Saint-Amand, one box plant in Mortagne, and one sheet plant in Cabourg); (ii) one box plant in Ovar, Portugal; and (iii) one box plant in Bilbao, Spain. Upon completion of the required French works council consultation and/or employee information processes, the parties expect to enter into a definitive share purchase agreement. The closing is expected by the end of the second quarter of 2025. All assets and liabilities at March 31, 2025 related to these locations have been recorded as held for sale in the accompanying condensed consolidated balance sheet.

The sale of these plants was agreed to with the European Commission as a remedy for IP’s acquisition of DS Smith, as published on the European Commission’s website on January 24, 2025. The conclusion of the divestment is subject to the European Commission’s approval of the proposed purchaser.

Reconciliation of Net earnings (loss) to Adjusted operating earnings (loss)

Adjusted Operating Earnings and Adjusted Operating Earnings Per Share are non-GAAP measures defined as net earnings (loss) (a GAAP measure) excluding net special items and non-operating pension expense (income). Net earnings (loss) and Diluted earnings (loss) per share are the most directly comparable GAAP measures. The Company calculates Adjusted Operating Earnings by excluding the after-tax effect of non-operating pension expense (income) and net special items, as described in greater detail below, from net earnings (loss) reported under GAAP. Adjusted Operating Earnings Per Share is calculated by dividing Adjusted Operating Earnings by diluted average shares of common stock outstanding. Management uses these non-GAAP measures to focus on ongoing operations and believes that such non-GAAP measures are useful to investors in assessing the operational performance of the Company and enabling investors to perform meaningful comparisons of past and present consolidated operating results. The Company believes that using these non-GAAP measures, along with the most directly comparable GAAP measures, provides for a more complete analysis of the Company's results of operations.

Non-operating pension expense (income) represents amortization of prior service cost, amortization of actuarial gains/losses, expected return on assets and interest cost. The Company excludes these amounts from our Adjusted Operating Earnings as the Company does not believe these items reflect ongoing operations. These particular pension cost elements are not directly attributable to current employee service. The Company includes service cost in our non-GAAP measure as it is directly attributable to employee service, and the corresponding employees’ other compensation elements, in connection with ongoing operations.

The following is a reconciliation of Net earnings (loss) to Adjusted operating earnings (loss) on a total basis. Additional detail is provided below regarding the net special items expense (income) referenced in the charts below.

(f)	Interest income on tax overpayments in prior years associated with the settlement of certain tax audits recorded in interest expense, net.

The following is a reconciliation of Net earnings (loss) to Adjusted operating earnings (loss) on a per share basis:

	Three Months Ended March 31,				Three Months Ended December 31,

Adjusted operating earnings (loss) per share	$	0.23	$	0.17	$	(0.02)

Cash provided by (used for) operations totaled $(288) million and $395 million for the first three months of 2025 and 2024, respectively. Free cash flow in the first three months of 2025 and 2024 was $(618) million and $144 million, respectively. Cash used for operations during the first quarter of 2025 primarily reflects the timing of our annual incentive compensation payout and the payment of transaction costs associated with the closing of the DS Smith acquisition and other transformation related costs for a total impact of approximately $670 million. Additionally, first quarter of 2025 free cash flow reflects increased capital spending in line with our capital spending plan for 2025. The Company generated meaningful cash receipts outside of free cash flow through the sale of certain assets along with the receipt of insurance recoveries related to the Ixtac, Mexico box plant fire.

Free cash flow is a non-GAAP measure, which equals cash provided by operations less capital expenditures, and the most directly comparable GAAP measure is cash provided by (used for) operations. Management utilizes this measure in connection with managing our business and 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, pay dividends, repurchase stock, service debt and make investments for future growth. It should not be inferred that the entire free cash flow amount is available for discretionary expenditures.

The following is a reconciliation of cash provided by operations to free cash flow:

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

Refer to the Effects of Net Special Items Expense (Income) section on page 29 for details of net special items expense (income) discussed below.

Net sales

The increase in the first quarter of 2025 compared to the fourth quarter of 2024 and the first quarter of 2024 was primarily driven by the addition of the newly acquired DS Smith business as a result of the completed acquisition in the first quarter of 2025. Additional details on net sales are provided in the Business Segment Operating Results section below.

Cost of products sold

Net special items charges of $70 million, $15 million and $35 million in the first quarter of 2025 and 2024 and the fourth quarter of 2024, respectively, are included in cost of products sold. The first quarter of 2025 includes $1.09 billion for DS Smith (including $70 million of special items charges). Compared to the fourth quarter of 2024, there were decreases of $93 million in raw materials, offset by increases of $54 million in fuel expense. Compared to the first quarter of 2024, cost of products sold was impacted by $320 million for decreases in raw materials and increases in insurance recoveries and one-time energy credits received, offset by lower maintenance and fuel expenses of $86 million.

Selling and administrative expenses

Net special items charges of $113 million, $5 million and $43 million in the first quarter of 2025 and 2024 and the fourth quarter of 2024, respectively, are included in selling and administrative expenses. The first quarter of 2025 includes $123 million for DS Smith (including $49 million of special items charges). Compared to the fourth quarter of 2024, there were decreases in incentive compensation and medical benefit costs. Compared to the first quarter of 2024, there were decreases in medical benefit costs offset by incentive compensation and other costs.

Depreciation and amortization

Depreciation expense includes $197 million, $5 million and $233 million for the first quarter of 2025 and 2024 and the fourth quarter of 2024, respectively, for accelerated depreciation related to mill and other 80/20 strategic actions. The first quarter of 2025 includes $107 million for DS Smith.

31

Distribution expenses

The first quarter of 2025 includes $140 million for DS Smith. Compared to the fourth quarter of 2024 and the first quarter of 2024, there were decreases in freight expense of $4 million and $43 million, respectively.

Taxes other than payroll and income taxes

Net special items charges of $50 million in the first quarter of 2025 are included in taxes other than payroll and income taxes. The first quarter of 2025 includes $5 million for DS Smith.

Interest expense, net

Net special items includes income of $10 million in interest expense, net for the first quarter of 2024. The first quarter of 2025 includes $24 million for DS Smith.

Income tax provision (benefit)

An income tax benefit of $31 million was recorded for the first quarter of 2025 and the reported effective income tax rate was 23%. Excluding a benefit of $45 million related to the tax effects of net special items and a benefit of $1 million related to the tax effects of non-operating pension expense, the operational effective income tax rate was 13% for the first quarter of 2025.

An income tax benefit of $78 million was recorded for the fourth quarter of 2024 and the reported effective income tax rate was 35%. Excluding a benefit of $36 million related to the tax effects of net special items and expense of $2 million related to the tax effects of non-operating pension income, the operational effective income tax rate was 88% for the fourth quarter of 2024. The operational and reported effective income tax rates were lower in the first quarter of 2025 than in the fourth quarter of 2024 primarily due to the timing and magnitude of the accelerated depreciation expense recorded in the fourth quarter of 2024 associated with the closure of the Georgetown, South Carolina mill.

An income tax provision of $27 million was recorded for the first quarter of 2024 and the reported effective income tax rate was 32%. Excluding a benefit of $4 million related to the tax effects of net special items and expense of $3 million related to the tax effects of non-operating pension income, the operational effective income tax rate was 31% for the first quarter of 2024. The operational and reported effective income tax rates were lower in the first quarter of 2025 than in the first quarter of 2024 primarily due to a tax benefit for equity-based compensation in the first quarter of 2025 and a tax expense for equity-based compensation in the first quarter of 2024.

The following is a reconciliation of the net income tax provision (benefit) to the operational income tax provision (a non-GAAP financial measure) and the reported effective income tax rate to the operational effective income tax rate (a non-GAAP financial measure):

	Three Months Ended
	March 31,								December 31,
In millions (except rates)	2025				2024				2024
	Provision (Benefit)		Rate		Provision (Benefit)		Rate		Provision (Benefit)		Rate
Income tax provision (benefit) and reported effective income tax rate	$	(31)	23	%	$	27	32	%	$	(78)	35	%
Income tax effect - non-operating pension (income) expense and special items	46				1				34
Operational Tax Provision and Operational Effective Tax Rate	$	15	13	%	$	28	31	%	$	(44)	88	%

The operational income tax provision and operational effective income tax rate are non-GAAP financial measures and are calculated by adjusting the income tax provision from continuing operations and rate to exclude the tax effect of net special items and non-operating pension expense (income). The most directly comparable GAAP measures are the reported income tax provision and effective income tax rate, respectively. Management believes that this presentation provides useful information to investors by providing a meaningful comparison of the income tax rate between past and present periods.

The Company currently operates in three segments: Packaging Solutions North America, Packaging Solutions EMEA and Global Cellulose Fibers.

Sales	$	643	$	704	$	662
Business Segment Operating Profit (Loss)	$	17	$	(47)	$	(250)

Global Cellulose Fibers sales were lower, reflecting lower sales prices from prior index movements and lower sales volumes driven by the mill strategic actions taken in the fourth quarter of 2024, partially offset by a favorable product mix. Cost of products sold decreased by $25 million and was impacted by improved mill reliability and lower economic downtime. Planned maintenance downtime costs in the first quarter of 2025 were higher compared with the fourth quarter of 2024. Input costs were higher as higher energy costs were partially offset by lower chemical and wood costs. Selling and administrative expenses decreased $31 million driven by lower employee incentive compensation and medical benefit expenses. Depreciation and amortization expense was $228 million lower as the fourth quarter of 2024 included $215 million of accelerated depreciation related to the closure of the Georgetown, South Carolina mill.

Compared with the first quarter of 2024, sales in the first quarter of 2025 were lower, as higher average sales prices and an improved product mix were more than offset by lower commodity volumes driven by the mill strategic actions taken in the fourth quarter of 2024. Cost of products sold decreased $90 million and was impacted by lower sales volumes and lower planned maintenance downtime costs partially offset by higher input costs, primarily for energy costs. Selling and administrative expense was $15 million lower and was impacted by lower employee medical costs. Distribution costs were $15 million lower reflecting lower sales volumes.

Entering the second quarter of 2025, sales volumes are expected to be stable. Planned maintenance downtime costs in the second quarter of 2025 are expected to be higher compared with the first quarter of 2025. Operating costs are expected to be stable. Input costs are expected to be lower driven by energy costs.

Cash provided by (used for) operations totaled $(288) million and $395 million for the first three months of 2025 and 2024, respectively. Cash provided by (used for) working capital components (accounts receivable, contract assets and inventory less accounts payable and accrued liabilities, interest payable and other) totaled $(622) million for the three months ended March 31, 2025 compared with cash provided by (used for) working capital components of $32 million for the three months ended March 31, 2024. The first quarter of 2025 cash used for operations includes certain significant payments that, in total, impacted operating cash flow by $670 million. This includes approximately $80 million of severance payments and approximately $240 million of DS Smith related transaction costs. This amount also includes the cash impact from the 2024 incentive compensation and other benefit payments made in the first quarter of 2025.

Cash provided by (used for) investment activities totaled $237 million in the first three months of 2025 compared with $(247) million in the first three months of 2024. The increase in cash provided by investment activities is mainly due to proceeds from the sale of fixed assets of $83 million, proceeds from insurance recoveries of $28 million and net cash acquired from acquisitions of $415 million, offset by higher capital expenditures of $79 million.

Capital expenditures totaled $330 million in the first three months of 2025, compared to $251 million in the first three months of 2024. Full-year 2025 capital expenditures are currently expected to be approximately $1.8 billion to $1.9 billion, or 100% to 106% of depreciation and amortization.

Financing activities for the first three months of 2025 included a $233 million net increase in debt versus a $3 million net decrease in debt during the comparable 2024 three-month period.

During the first quarter of 2025, the Company borrowed $175 million under its commercial paper program and $64 million under its committed bank facility.

See Note 15 - Debt of the Condensed Notes to the Consolidated Financial Statements for a discussion of various debt-related actions taken by the Company during the three months ended March 31, 2025.

There were no early debt reductions for the three months ended March 31, 2025 and 2024, respectively.

Maintaining an investment-grade credit rating is an important element of International Paper’s financing strategy. At March 31, 2025, the Company held long-term credit ratings of BBB (stable outlook) and Baa2 (stable outlook) by S&P and Moody’s, respectively. In addition, the Company held short-term credit ratings of A2 and P2 by S&P and Moody's, respectively, for borrowings under the Company's commercial paper program.

At March 31, 2025, International Paper’s USD denominated credit facilities totaled $1.9 billion, which is comprised of the $1.4 billion contractually committed bank credit agreement and up to $500 million under the receivables securitization program. Management believes that the Company's credit agreements are adequate to cover expected operating cash flow variability during the current economic cycle. The credit agreements generally provide for interest rates at a floating rate index plus a pre-determined margin dependent upon International Paper’s credit rating. At March 31, 2025, the Company had no borrowings outstanding under the $1.4 billion credit agreement or the $500 million receivables securitization program. The Company’s credit agreements are not subject to any restrictive covenants other than the financial covenants as disclosed in Note 15 - Debt, and the borrowings under the receivables securitization program being limited by eligible receivables. The Company was in compliance with all its debt covenants at March 31, 2025, and was well below the thresholds stipulated under the covenants as defined in the credit agreements. The financial covenants do not restrict any borrowings under the credit agreements.

In addition to the $1.4 billion capacity under the Company's credit agreements, International Paper has a commercial paper program with a borrowing capacity of $1.0 billion supported by its $1.4 billion credit agreement. Under the terms of the program, individual maturities on borrowings may vary, but not exceed one year from the date of issue. Interest bearing notes may be issued either as fixed or floating rate notes. As of March 31, 2025, the Company had $175 million of borrowings outstanding under the commercial paper program.

On February 14, 2025, DS Smith, a wholly owned subsidiary of International Paper, announced separate invitations (each such invitation, a “Consent Solicitation”) to eligible holders of its outstanding (i) €600 million 0.875 percent Notes due September 12, 2026 (the “2026 Notes”); (ii) €850 million 4.375 percent Notes due July 27, 2027 (the “2027 Notes”); (iii) £250 million 2.875 percent Notes due July 26, 2029 (the “2029 Notes”); and (iv) €650 million 4.500 percent Notes due July 27, 2030 (the “2030 Notes”), in each case issued by DS Smith under its Euro-Medium Term Note Programme (each a “Series” and, together, the “Notes”) to consent to, amongst other things, certain modifications to the terms and conditions (the “Conditions”) of, and the trust deed (the “Trust Deed”) for, the relevant Series to provide for (i) the removal of the obligation for DS Smith to prepare audited and unaudited consolidated accounts; (ii) the amendment of certain events of default to align more closely with certain equivalent provisions included in the documentation relating to debt securities issued by International Paper and to allow additional flexibility for potential reorganization of DS Smith’s subsidiaries, if required, now that DS Smith and its subsidiaries are part of the International Paper group; and (iii) certain consequential modifications to the applicable Conditions and Trust Deed for the relevant Series in relation to items (i) and (ii) above (together, the “Proposed Amendments”). As consideration for the holders of the Notes consenting to the Proposed Amendments, it was proposed that DS Smith procure a guarantee from International Paper, to guarantee the payment obligations of DS Smith under the Notes. The full principal amount of each Series of Notes issued by DS Smith remains outstanding as of the date hereof. On March 10, 2025, DS Smith has executed and delivered a Supplemental Trust Deed in respect of each Series to implement the Proposed Amendments, and International Paper has executed and delivered a deed of guarantee in respect of each Series to guarantee the payment obligations of DS Smith under such Series.

In March 2025, the Company amended and restated its £1.25 billion credit facility agreement to, among other things (i) replace its obligation to prepare audited and unaudited consolidated accounts and instead provide International Paper’s account information, on the same terms as International Paper’s existing credit facilities, (ii) amend the financial covenant in the credit facility agreement to align with financial covenants given by International Paper in its existing credit facilities, (iii) amend certain events of default, and undertakings to align more closely with certain equivalent provisions included in the documentation relating to the existing financings of International Paper and to allow additional flexibility for potential reorganization of DS Smith’s subsidiaries, if required, now that DS Smith and its subsidiaries are part of the International Paper

group. The multi-currency credit facility allows for GBP, EUR and USD borrowings and provides for interest rates at a floating rate index plus a pre-determined margin. Credit facility borrowings are denominated in the currency that aligns with the Company's cashflows. At March 31, 2025, the Company had €840 million (approximately $909 million at the current exchange rate) borrowings outstanding under the credit facility. The Company’s credit facility agreement is not subject to any restrictive covenants other than that International Paper must comply with the same negative covenants as per its existing credit facilities. IP was in compliance with all its debt covenants at March 31, 2025, and was well below the thresholds stipulated under the covenants as defined in the credit facility agreement. Further the financial covenants do not restrict any borrowings under the credit facility agreement.

In April 2025, the Company amended and restated its credit facility agreement to, among other things (i) replace its obligation to prepare audited and unaudited consolidated accounts and instead provide International Paper’s account information, on the same terms as International Paper’s existing credit facilities, (ii) amend the financial covenant in the credit facility agreement to align with financial covenants given by International Paper in its existing credit facilities, (iii) amend certain events of default, and undertakings to align more closely with certain equivalent provisions included in the documentation relating to the existing financings of International Paper and to allow additional flexibility for potential reorganization of DS Smith’s subsidiaries, if required, now that DS Smith and its subsidiaries are part of the International Paper group. The credit facility agreement provides for interest rates at a fixed rate for each facility. At March 31, 2025, the Company had €200 million borrowings outstanding under the €200 million credit facility agreement. The Company’s credit facility agreement is not subject to any restrictive covenants other than that International Paper must comply with the same negative covenants as per its existing credit facilities. IP was in compliance with all its debt covenants at March 31, 2025, and was well below the thresholds stipulated under the covenants as defined in the credit facility agreement. Further the financial covenants do not restrict any borrowings under the credit facility agreement.

The Company also has a €60 million committed bank facility that matures in December 2026. In April 2025, the Company amended and restated its credit facility agreement to, among other things (i) replace its obligation to prepare audited and unaudited consolidated accounts and instead provide International Paper’s account information, on the same terms as International Paper’s existing credit facilities, (ii) amend the financial covenant in the credit facility agreement to align with financial covenants given by International Paper in its existing credit facilities, (iii) amend certain events of default, and undertakings to align more closely with certain equivalent provisions included in the documentation relating to the existing financings of International Paper and to allow additional flexibility for potential reorganization of DS Smith’s subsidiaries, if required, now that DS Smith and its subsidiaries are part of the International Paper group. The multi-currency credit facility allows for GBP, EUR and USD borrowings. At March 31, 2025, there were no borrowings outstanding under this agreement. The Company has a £50 million uncommitted bank facility. At March 31, 2025 the Company had $63 million borrowings outstanding under this agreement.

International Paper expects to meet projected capital expenditures, service existing debt, meet working capital and dividend payments and make common stock and/or debt repurchases for the next 12 months and for the foreseeable future thereafter with current cash balances and cash from operations, supplemented as required by its existing credit facilities. The Company will continue to rely on debt and capital markets for the majority of any necessary long-term funding not provided by operating cash flows. Funding decisions will be guided by our capital structure planning objectives. The primary goals of the Company’s capital structure planning are to maximize financial flexibility and maintain appropriate levels of liquidity to meet our needs while managing balance sheet debt and interest expense. We have repurchased, and may continue to repurchase, our common stock (under our existing share repurchase program) and debt (including in open market purchases) to the extent consistent with this capital structure planning, and subject to prevailing market conditions, our liquidity requirements, applicable securities laws requirements, and other factors. The majority of International Paper’s debt is accessed through global public capital markets where we have a wide base of investors.

During the first three months of 2025, International Paper used 3.4 million shares of treasury stock for various incentive plans. International Paper also acquired 1.1 million shares of treasury stock, related to restricted stock tax withholdings during the first three months of 2024. Payments of restricted stock withholding taxes totaled $62 million during this period. Our current share repurchase program approved by our Board of Directors ("Board") on October 11, 2022, which does not have an expiration date, has approximately $2.96 billion aggregate amount of shares of common stock remaining authorized for purchase as of March 31, 2025. During the three months ended March 31, 2025, no shares of common stock were repurchased under our share repurchase program.

During the first three months of 2024, International Paper used approximately 1.9 million shares of treasury stock for various incentive plans. International Paper also acquired 0.6 million shares of treasury stock, related to restricted stock tax withholding during the first three months of 2024. Payments of restricted stock withholding taxes totaled $22 million. During the three months ended March 31, 2024, no shares of common stock were repurchased under our share repurchase program.

36

Cash dividend payments related to common stock totaled $244 million and $161 million for the first three months of 2025 and 2024, respectively. Dividends were $0.4625 per share for the first three months of 2025 and 2024.

Our U.S. and U.K. pension plans are currently fully funded and we do not anticipate any required cash contributions for the next 12 months.

Variable Interest Entities

Information concerning variable interest entities is set forth in Note 14 in the Company's Annual Report.

CRITICAL ACCOUNTING POLICIES AND SIGNIFICANT ACCOUNTING ESTIMATES

The preparation of financial statements in conformity with accounting principles generally accepted in the United States requires International Paper 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 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 International Paper, and that may require judgments by management that affect their application, include accounting for contingencies, impairment or disposal of long-lived assets, goodwill and other intangible assets, pensions and income taxes.

The Company has included in its Annual Report a discussion of these critical accounting policies, which are important to the portrayal of the Company’s financial condition and results of operations and may require management’s judgments. Except as described below, the Company has not made any changes in these critical accounting policies during the first three months of 2025.

Business Combinations

The Company’s acquisitions of businesses are accounted for in accordance with ASC 805, "Business Combinations". We allocate the total purchase price of the assets acquired and liabilities assumed based on their estimated fair value as of the business combination date. In developing estimates of fair values for long-lived assets, including identifiable intangible assets, the Company utilizes a variety of inputs including forecasted cashflows, anticipated growth rates, discount rates, appraisals, market valuations, estimated replacement costs and depreciation, and obsolescence factors. Determining the fair value for specifically identified intangible assets such as customer lists and developed technology involves judgment. We may refine our estimates and make adjustments to the assets acquired and liabilities assumed over a measurement period, not to exceed one year. Upon the conclusion of the measurement period or the final determination of the values of assets acquired and liabilities assumed, whichever comes first, any subsequent adjustments are charged to the consolidated statements of earnings. Subsequent actual results of the underlying business activity supporting the goodwill and specifically identified intangible assets could change, requiring us to record impairment charges or adjust their economic lives in future periods.

CAUTIONARY STATEMENT REGARDING FORWARD-LOOKING STATEMENTS

Certain statements in this Quarterly Report on Form 10-Q that are not historical in nature may be considered “forward-looking statements” within the meaning of the Private Securities Litigation Reform Act of 1995, as amended.

In addition, other risks and uncertainties not presently known to the Company or that we currently believe to be immaterial could affect the accuracy of any forward-looking statements. The Company undertakes no obligation to publicly update any forward-looking statements, whether as a result of new information, future events or otherwise.

ITEM 4.CONTROLS AND PROCEDURES

Evaluation of Disclosure Controls and Procedures:

Disclosure controls and procedures are controls and other procedures designed to ensure that information required to be disclosed in our reports filed or submitted under the Securities Exchange Act of 1934, as amended (the "Exchange Act"), is recorded, processed, summarized and reported (and accumulated and communicated to management, including our Chief Executive Officer and Chief Financial Officer, to allow timely decisions regarding required disclosure) within the time periods specified in the SEC’s rules and forms. As of the end of the period covered by this Form 10-Q, we conducted an evaluation, under the supervision and with the participation of our management, including the Chief Executive Officer and Chief Financial Officer, of the effectiveness of our disclosure controls and procedures pursuant to Rules 13a-15 and 15d-15 of the Exchange Act. Based upon that evaluation, our Chief Executive Officer and Chief Financial Officer concluded that the Company’s disclosure controls and procedures were effective as of March 31, 2025 (the end of the period covered by this Form 10-Q).

38

Changes in Internal Control over Financial Reporting:

As previously disclosed, on January 31, 2025, we completed the acquisition of the entire issued and to be issued share capital of DS Smith. See Note 8 - Acquisitions to the Condensed Consolidated Financial Statements for additional information. We are in the process of integrating DS Smith into our systems and control environment. This ongoing integration process may result in changes in our internal control over financial reporting.

Except as described above, there have been no changes in our internal control over financial reporting during the quarter ended March 31, 2025 that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

Except as set forth in Note 13 – Commitments and Contingencies of the Condensed Notes to the Consolidated Financial Statements in this Form 10-Q, the Company is not subject to any administrative or judicial proceeding arising under any Federal, State or local provisions that have been enacted or adopted regulating the discharge of materials into the environment or primarily for the purpose of protecting the environment that is likely to result in monetary sanctions of $1 million or more.

ITEM 1A.RISK FACTORS

Other than as set forth below, there have been no material changes from the risk factors disclosed in our Annual Report on Form 10-K (Part I, Item 1A) for the period ended December 31, 2024.

Changes in international conditions or other risks arising from conducting business internationally could adversely affect our business and operations.

As a global producer of renewable fiber-based packaging and pulp products, we operate in many different countries. As a result, we are vulnerable to risks related to our international operations. These risks, which can vary substantially by country, include economic or political instability, geopolitical events, corruption, anti-American sentiment, expropriation measures, social and ethnic unrest, natural disasters, military conflicts and terrorism, the regulatory environment (including the risks of operating in developing or emerging markets in which there are significant uncertainties regarding the interpretation and enforceability of legal requirements and the enforceability of contractual rights and intellectual property rights), adverse currency fluctuations, foreign exchange control regimes (including restrictions on currency conversion), downturns or changes in economic conditions (including in relation to commodity inflation and tariffs), adverse tax consequences or rulings, import restrictions, controls or other trade protection measures, economic sanctions, health guidelines and safety protocols, nationalization, changes in social, political or labor conditions, and adverse developments regarding sustainability, environmental regulations and trade policies and agreements, any of which risks could negatively affect our financial results. For example, a portion of our sales could be adversely affected by changes in economic conditions and demographics, including as a result of tariffs. Trade protection measures in favor of local producers of competing products, including governmental subsidies, tariffs, tax benefits and other measures may give local producers a competitive advantage and adversely impact our operating results and our business prospects in these countries. Likewise, disruption in existing trade agreements or increased trade friction between countries (such as in relation to the trade tensions between the U.S. and China) could have a negative effect on our business and results of operations by restricting the free flow of goods and services across borders. Additionally, the U.S. government recently increased certain rates and broadened the scope of certain tariffs imposed on goods imported into the U.S., such as from China, which may strain international trade relations and increase the risk that foreign governments implement retaliatory tariffs on goods imported from the United States. Specifically, the U.S. government implemented tariffs on certain foreign goods and may implement additional tariffs on foreign goods. If lasting, such tariffs and any further legislation or actions taken by the U.S. federal government that restrict trade, such as additional tariffs, trade barriers, and other protectionist or retaliatory measures taken by governments in Europe, Asia, and other countries, could adversely impact our ability to sell products and services in our international markets. Tariffs could increase the cost of our products and the components and raw materials that go into our manufacturing process. These increased costs could adversely impact the profit margin that we earn on our products, which could make our products less competitive and reduce consumer demand. Countries have and may continue to also adopt other protectionist measures that could limit our ability to offer our products and services. Conversely, these tariffs and retaliatory tariffs may be subject to negotiations which could lower or remove them in the near or longer term with a return to more normalized trade conditions in some instances. Due to this uncertainty, the ultimate impact of any tariffs and trade tension is unclear and will depend on various factors, including if there are negotiated bilateral agreements to remove or lower tariffs, and the timing, amount, scope, and nature of the tariffs that remain implemented.

We may continue to be adversely affected by ongoing geopolitical instability and the economic consequences and disruptions arising therefrom, including as the result of the military conflict between Russia and Ukraine, the conflict in the Middle East, and increasing tensions between China and Taiwan. These risks may be further heightened in the event of the expansion in the scope or escalation of any such conflicts. In addition, changes to economic sanctions programs, could put us at risk of violating sanctions as a result of an existing presence in a newly sanctioned jurisdiction or relationship with a newly sanctioned entity if we fail or are unable to end such presence or relationship in a timely manner.

40

In addition, we are subject to laws related to operations in foreign jurisdictions, including laws prohibiting bribery of government officials and other corrupt practices. Anti-bribery laws such as the U.K. Bribery Act 2010, the Foreign Corrupt Practices Act of 1977, and similar worldwide anti-corruption laws generally prohibit companies and their intermediaries from making improper payments to public officials for the purpose of obtaining or retaining business. Further, the U.S. Department of the Treasury’s Office of Foreign Assets Control and other non-U.S. government entities maintain economic sanctions targeting various countries, persons and entities. We are also subject to the laws and regulations of governmental and regulatory agencies. Failure to comply with domestic or foreign laws could result in various adverse consequences for us including the imposition of civil or criminal sanctions, reputational damage and the prosecution of executives overseeing international operations.

We are exposed to the translation of the results of overseas subsidiaries into their respective reporting currencies, as well as the impact of currency fluctuations on their commercial transactions denominated in foreign currencies. Adverse movements in foreign exchange rates relating to foreign currency denominated commodities, assets and liabilities, and transactions could have a material impact on our business, financial condition, results of operations and/or future prospects.

3.    Payment of Withholding Taxes. Generally, to pay withholding taxes due on an Award upon payout, the Company will reduce the number of restricted stock units paid to you by an amount sufficient to pay the minimum statutorily required withholding taxes.

4.    Method of Determining Actual Award and Removal of Restrictions.

(a)As soon as reasonably practicable after the Vesting Date (but in no event later than 30 days thereafter), the number of restricted stock units that have vested under this Award will be determined and you will receive, in settlement of the Award, a number of unrestricted shares of Company common stock equal to the number of restricted stock units that vest.

(b)You will receive accelerated vesting of all outstanding restricted stock units underlying this Award upon a termination of employment for the following events: (i) death or (ii) Disability. In these events, all unvested restricted stock units will accelerate and you (or, if applicable, your beneficiary or estate) will receive a number of unrestricted shares of Company common stock equal to the number of restricted stock units that would have vested upon the Vesting Date. Such restricted stock units will be settled, and the Company common stock delivered to you as soon as reasonably practicable following the date of your termination of employment due to death or Disability (but in no event later than 30 days thereafter).

(c)You will receive a prorated, accelerated vesting of all outstanding restricted stock units underlying this Award upon termination of employment in connection with a divestiture made by the Company or upon an elimination of position by the Company. Your award will be prorated based upon your months of service prior to your termination and will vest immediately and will be settled in shares of our common

Exhibit 10.5

stock or an equivalent value in cash, as applicable, as soon as reasonably practicable following the date of your termination of employment.

(d)Your Award will be forfeited and cancelled if you cease to be an active employee of the Company prior to the Vesting Date for any reason other than death, Disability, or termination due to a divestiture made by the Company or upon an elimination of position by the Company.

(e)In the event of a Change of Control of the Company, the Award will be treated as described in the Plan.

(f)In the event the Company‘s financial statements are required to be restated as a result of errors, omissions or fraud, the Company may recover all or a portion of the Award with respect to any fiscal year of the Company during the Vesting Period the financial results of which are negatively affected by such restatement. Additional mandatory clawback provisions apply to current and former executive officers, as defined in the Company’s Clawback Policy.

5.    Changes in Stock. In the event of any stock dividend, split, reclassification or other analogous change in capitalization, or any distribution (other than regular cash dividends) to holders of the Company’s common stock, the Committee will make such adjustments, if any, as it deems to be equitable in the number of restricted stock units awarded to you, in accordance with administrative guidelines.

(c)You will receive prorated RSUs in the following events: (i) termination of your employment if you are eligible for a termination allowance (and, in the United States, you sign the Company’s termination agreement and release in connection with the payment of a termination allowance); (ii) termination of your employment as a result of the Company’s divestiture of your business; or (iii) voluntary resignation after retirement eligibility (defined, for purposes of this Award, as either your attainment of age 65, or your attainment of age 55 with at least ten years of service with the Company). In these events, the RSUs will be prorated based on (x) the number of RSUs granted to you, multiplied by (y) a fraction, the numerator of which is the number of months you

Exhibit 10.8

were employed for at least one day during the Restriction Period, and the denominator of which is the total number of months in the Restriction Period, minus (z) the number of RSUs (if any) that previously vested prior to the date of termination of your employment.

(d)You will receive accelerated vesting of all outstanding restricted stock or restricted stock units underlying this Award upon a termination of employment for the following events: (i) death; (ii) Disability; or (iii) Involuntary Termination for reasons other than for Cause (as defined in the International Paper Company 2024 Long-Term Incentive Compensation Plan). In these events, all unvested restricted shares or restricted stock units will accelerate and you (or, if applicable, your beneficiary or estate) will receive a number of unrestricted shares of Company common stock equal to the number of restricted shares or restricted stock units that would have vested upon the Vesting Date. Such restricted shares or restricted stock units will be settled, and the Company common stock delivered to you as soon as reasonably practicable following the date of your termination of employment due to death or Disability (but in no event later than 30 days thereafter).

(e)Your Award will be forfeited and cancelled upon the following events: (i) termination of your employment for Cause, (ii) in the United States, your refusal to sign the Company’s termination agreement and release in connection with the payment of a termination allowance, (iii) voluntary resignation before retirement eligibility, (iv) violation of a restrictive covenant agreement, such as a Non-Competition, Non-Solicitation or Confidentiality Agreement, (v) failure of an Executive Officer to provide one-year’s notice of retirement, (vi) your Misconduct, or (vii) termination of your employment on or before February 15 of the first year of the three-year Restriction Period for the Award.

(f)Except as may be provided in a Change in Control Agreement, in the event of a Change in Control of the Company, the Award will be treated as described in the Administrative Guidelines for the Plan.

(f)    In the event the Company’s financial statements are required to be restated as a result of errors, omissions, or fraud, the Company may recover all or a portion of any Award with respect to any fiscal year of the Company in accordance with administrative guidelines. Additional mandatory clawback provisions apply to current and former executive officers, as defined in the Company’s Clawback Policy.

5.    Changes in Stock. In the event of any stock dividend, split, reclassification or other analogous change in capitalization, or any distribution (other than regular cash dividends) to holders of the Stock, the Committee will make such adjustments, if any, as it deems to be equitable in the number of RSUs awarded to you.

6.    Other Terms and Conditions

(b)The Board or the Committee may, at any time and from time to time, amend, modify or terminate the Plan without shareowner approval, subject to certain limitations described in the plan.

Exhibit 10.8

(e)Participation in the Plan and receipt of this Award will not give you any right to a subsequent award, or any right to continued employment by the Company for any period, nor will the granting of an Award give the Company any right to your continued services for any period. You understand that this Award is in addition to, and not a part of, your annual salary.

(f)You agree that if execution of one or more restrictive covenant agreements is required, this Award will be contingent upon your execution of such agreement(s).

(g)This Award is intended to be exempt from Section 409A of the Internal Revenue Code of 1986, as amended (“Section 409A”), and will be interpreted in accordance with such intent.

(h)Eligibility to participate in the Plan, and any subsequent offers and participation, are not intended to constitute a public offer in any jurisdiction.

(i)The Plan is offered and administered by the Company and not by your employing entity (if different). All Plan documents, and any links by which you may access these documents, originate from and are maintained by the Company.

(j)All Plan documents may be communicated and stored electronically using means that are secure, private and accessible to the relevant parties. You consent to the sole use of electronic communications (including, without limitation, offer and acceptance) in connection with the Plan.

(m)If you are a mobile employee, meaning that you are based in different jurisdictions during the course of your employment and/or your participation in the Plan or you are, or may be, subject to tax in more than one jurisdiction, you are strongly encouraged to inform the Company and to consult your personal tax adviser(s) regarding the tax treatment of the Award.

(n)The Award and related benefits under the Plan are in no way secured, guaranteed or warranted by the Company or any Affiliate and participation in the Plan involves certain risks. You should exercise caution in relation to Plan offers and/or participation. You should obtain independent professional advice if you are in doubt about any of the contents of the Plan documents and before taking actions in relation to the Plan.

(o)You acknowledge that there is a risk that Shares may fall or rise in value. Market forces may impact the price of Shares and, in the worst case, the market value of the Shares subject to your RSUs may become zero. You agree that neither the Company nor any Affiliate is liable for any loss due to movements in Share value.

(p)If Shares are traded in a currency that is not the currency of your jurisdiction, the value of the Shares to you may also be affected by movements in the exchange rate. There may also be an

Exhibit 10.8

exchange rate risk in relation to any Plan-related currency that is not the currency of your jurisdiction. You agree that neither the Company nor any Affiliate is liable for any loss due to movements in the exchange rate or any charges imposed in relation to the conversion or transfer of currency.

(q)You acknowledge that rules on dealing notification, insider trading and market abuse (including the terms of the Company’s Insider Trading Policy) may from time to time apply to the Award and related benefits and may prohibit or delay actions or decisions in relation to such payments or benefits. You agree that you are solely responsible for compliance with such rules and that neither the Company nor any Affiliate is liable for any loss due to such rules or for any breaches of such rules by you.

(r)Under local exchange controls, currency controls or foreign asset reporting requirements, you may be subject to certain notification, approval and/or repatriation obligations with respect to Shares and any funds you may transfer or receive in connection with the Plan. Among other things, such aforementioned obligations may affect your ability to hold Shares, bring Shares into your jurisdiction, reinvest dividends and receive any applicable dividends or dividend equivalents, Share sale proceeds and other payments in a local or foreign account. You may further be subject to local securities law and/or exchange control restrictions and other obligations in the event of a resale of Shares. You agree that you are solely responsible for ensuring compliance with any such obligations that may apply to you in connection with the Plan, and the Company recommends that you obtain independent professional advice in this regard. In the event that you fail to comply with any such obligations, you agree that neither the Company nor any Affiliate is liable in any way for resulting fines or other penalties.

2.Restricted Stock Units.

(a)All restricted stock or restricted stock units issued under this Award will be contingently awarded with respect to the specific vesting period (the “Vesting Period”) as described in the Award Certificate set forth herein. The restricted shares or restricted stock units will vest on the date specified in the Award Certificate (the “Vesting Date”). The restricted shares or restricted stock units may not be sold, transferred, pledged or assigned at any time.

(b)Except as provided in 2(d), payout of an Award is contingent solely upon the passage of time and your continued service with the Company through the Vesting Date, and not on Company or individual performance.

(c)All dividend equivalent units accrued during the Vesting Period will be reinvested in additional restricted shares or restricted stock units (which will be allocated to the same Vesting Period and will be subject to the same terms and conditions as the original Award).

(d)If you experience an involuntary termination for reasons other than for Cause (as defined in the International Paper Company Amended and Restated 2009 Incentive Compensation Plan) prior to the Vesting Date, the vesting of the shares will automatically accelerate so that this Award will, immediately before the effective date of the involuntary termination, become fully vested for all of the shares of common stock subject to this Award.

3.    Payment of Withholding Taxes. Generally, to pay withholding taxes due on an Award upon payout, the Company will reduce the number of restricted shares or restricted stock units paid to you by an amount sufficient to pay the minimum statutorily required withholding taxes.

4.    Method of Determining Actual Award and Removal of Restrictions.

(a)As soon as reasonably practicable after the Vesting Date (but in no event later than 30 days thereafter), the number of restricted shares or restricted stock units that have vested under this Award will be determined and you will receive, in settlement of the Award, a number of unrestricted shares of Company common stock equal to the number of restricted shares or restricted stock units that vest.

(b)You will receive accelerated vesting of all outstanding restricted stock or restricted stock units underlying this Award upon a termination of employment for the following events: (i) death; (ii) Disability; or (iii) involuntary termination for reasons other than for Cause (as defined in the International Paper Company Amended and Restated 2009 Incentive Compensation Plan). In these events, all unvested restricted shares or restricted stock units will accelerate and you (or, if applicable, your beneficiary or estate) will receive a number of unrestricted shares of Company common stock equal to the number of restricted shares or restricted stock units that would have vested upon the Vesting Date. Such restricted shares or restricted stock units will be settled, and the Company common stock delivered to you as soon as reasonably practicable following the date of your termination of employment due to death or Disability (but in no event later than 30 days thereafter).

(c)Your Award will be forfeited and cancelled if you cease to be an active employee of the Company prior to the Vesting Date for any reason other than death, Disability or involuntary termination for reasons other than for Cause.

(d)Except as may be provided in a Change in Control Agreement to which you are a party (if any), in the event of a Change in Control of the Company, the Award will be treated as described in the Plan.

(e)In the event the Company’s financial statements are required to be restated as a result of errors, omissions or fraud, the Company may recover all or a portion of the Award with respect to any fiscal year of the Company during the Vesting Period the financial results of which are negatively affected by such restatement.

5.    Changes in Stock. In the event of any stock dividend, split, reclassification or other analogous change in capitalization, or any distribution (other than regular cash dividends) to holders of the Company’s common stock, the Committee will make such adjustments, if any, as it deems to be equitable in the number of restricted shares or restricted stock units awarded to you, in accordance with administrative guidelines. Additional mandatory clawback provisions apply to current and former executive officers, as defined in the Company’s Clawback Policy.

6.    Other Terms and Conditions.

(a)The Board or the Committee may, at any time and from time to time, amend, modify or terminate the Plan without shareowner approval, subject to certain limitations described in the Plan.

REVENUE RECOGNITION (Note)

Revenue from Contract with Customer [Abstract]

Revenue from Contract with Customer [Text Block]

Generally, the Company recognizes revenue on a point-in-time basis when the customer takes title to the goods 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, generally, is as the goods are produced.

Revenue Contract Balances

A contract asset is created when the Company recognizes revenue on its customized products prior to having an unconditional right to payment from the customer, which generally does not occur until title and risk of loss passes to the customer.

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 once control of the goods is transferred to the customer. The majority of our customer prepayments are received during the fourth quarter each year for goods that will be transferred to customers over the following twelve months. Contract liabilities of $33 million and $30 million are included in Other current liabilities in the accompanying condensed consolidated balance sheet as of March 31, 2025 and December 31, 2024, respectively. The Company also recorded a contract liability of $115 million related to a previous acquisition. The balance of this contract liability was $82 million and $84 million at March 31, 2025 and December 31, 2024, respectively, and is recorded in Other current liabilities and Other Liabilities in the accompanying condensed consolidated balance sheet.

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 prepayment from the customer, respectively.

Earnings Per Share [Abstract]

Earnings Per Share [Note Text Block]

Basic earnings per share is computed by dividing earnings by the weighted average number of common shares outstanding. Diluted earnings per share is computed assuming that all potentially dilutive securities were converted into common shares. There are no adjustments required to be made to net income for purposes of computing basic and diluted earnings per share. A reconciliation of the amounts included in the computation of basic earnings (loss) per share and diluted earnings (loss) per share is as follows:

Business Combination, Asset Acquisition, and Joint Venture Formation [Abstract]

Business Combination Disclosure [Text Block]

On January 31, 2025, the Company completed its acquisition of the entire issued and to be issued share capital of DS Smith. Upon closing, IP issued 0.1285 shares for each DS Smith share, resulting in the issuance of 178,126,631 new shares of IP common stock ("New Company Common Stock"). As a result of the share issuance, the holders of the New Company Common Stock own approximately 34.1% of the Company's outstanding share capital. Based on the issuance of 178,126,631 new shares and the closing price of $55.63 on the close of January 31, 2025, the total purchase consideration for the completed acquisition was approximately $9.9 billion. Acquisition-related costs were $87 million and $5 million for the three months ended March 31, 2025 and March 31, 2024, respectively, and were recorded in Selling and administrative expenses and Taxes other than payroll and income taxes in the accompanying condensed consolidated statement of operations. On February 4, 2025, the Company began trading the New Company Common Stock and continues to be listed on the New York Stock Exchange under the trading symbol "IP" and via a secondary listing on the London Stock Exchange under the trading symbol "IPC." The headquarters of the combined company is based in Memphis, Tennessee, and the EMEA headquarters has been established at DS Smith's existing main office in London.

The Company is accounting for the acquisition under ASC 805, "Business Combinations" and the results of operations have been included in International Paper's financial statements beginning with the date of acquisition.

The following table summarizes the provisional fair value assigned to assets and liabilities acquired as of January 31, 2025:

In millions
Cash and temporary investments	$	448
Accounts and notes receivable, net	1,386
Inventories	852
Other current assets	147
Plants, properties and equipment	6,429
Intangibles	4,327
Goodwill	4,048
Overfunded pension plan assets	79
Right of use assets	257
Deferred charges and other assets	56
Total assets acquired	18,029
Notes payable and current maturities of long-term debt	60
Accounts payable	1,654
Accrued payroll and benefits	240
Other current liabilities	608
Long-term debt	3,634
Deferred income taxes	1,520
Underfunded pension benefit obligation	78
Long-term lease obligations	177
Other liabilities	149
Total liabilities assumed	8,120
Net assets acquired	$	9,909

The purchase price and related allocation are preliminary and could be revised as a result of adjustments made to the purchase price, additional information obtained regarding assets acquired and liabilities assumed, review of contracts and revisions of provisional estimates of fair values, including, but not limited to, the completion of independent appraisals and valuations related to inventory, property, plant and equipment, acquired intangible assets, leases, taxes, contract assets and derivatives. Adjustments to provisional amounts will be finalized as new information becomes available, but within the adjustment period of up to one year from the acquisition date. Goodwill is not deductible for local income tax purposes and is primarily related to the value of new customers through expansion opportunities not reflected in the fair value of the existing customers relationships and the value of the intellectual property beyond selected life for trade names.

Since the date of acquisition, Net sales of $1.3 billion and Net earnings (loss) of $(107) million have been included in the Company's condensed consolidated statement of operations for the three months ended March 31, 2025.

The identifiable intangible assets acquired in connection with the acquisition of DS Smith included the following:

In millions	Estimated Fair Value		Average Useful Life
Customer relationships and lists	$	3,843	18 years
Tradenames, patents and trademarks, and developed technology	379		15 years
Software (a)	90		3 - 5 years
Other	15		Indefinite lived
Total	$	4,327

(a) Of this balance, $57 million has been placed in service and $33 million is in development.

Below are the consolidated results on an unaudited pro forma basis assuming the acquisition of DS Smith had closed on January 1, 2024:

	Three Months Ended March 31,
In millions	2025 (Unaudited)		2024 (Unaudited)
Net Sales	$	6,636	$	6,726
Net Earnings (Loss)	(107)		11

The unaudited pro forma information for the three months ended March 31, 2025 includes adjustments for additional amortization expense on identifiable intangible assets of $9 million and adjustments for additional depreciation expense on identifiable fixed assets of $6 million and eliminates the write-off of the estimated fair value of inventory of $70 million and the non-recurring integration costs associated with the acquisition of $65 million.

The unaudited pro forma information for the three months ended March 31, 2024 includes adjustments for additional amortization expense on identifiable intangible assets of $27 million, additional depreciation expense on identifiable fixed assets of $19 million, incremental expense of $70 million associated with the write-off of the estimated fair value of inventory and non-recurring integration costs associated with the acquisition of $65 million.

The unaudited pro forma consolidated financial information was prepared for comparative purposes only and includes certain adjustments, as noted above. The adjustments are estimates based on currently available information and actual amounts may have differed materially from these estimates. They do not reflect the effect of costs or synergies that would have been expected to result from the integration of the acquisition. The pro forma information does not purport to represent International Paper's actual results of operation as if the transaction described above would have occurred as of January 1, 2024, nor is it necessarily an indicator of future results.

In connection with the DS Smith acquisition, the European Commission issued its Phase I clearance of the business combination between International Paper and DS Smith on January 31, 2025, with the condition that International Paper commit to divest five European plants in Mortagne, Saint-Amand, and Cabourg (France), Ovar (Portugal) and Bilbao (Spain). The Company agreed to divest these locations and all assets and liabilities at March 31, 2025 related to these locations have been recorded as held for sale in the accompanying condensed consolidated balance sheet. On April 14, 2025, the Company announced it had entered into exclusive negotiations with Palm Group of Germany after receiving an irrevocable offer for the purchase of the European plants. The closing is expected by the end of the second quarter of 2025.

Income Tax Disclosure [Abstract]

Income Taxes [Note Text Block]

International Paper made income tax payments, net of refunds, of $45 million and $5 million for the three months ended March 31, 2025 and 2024, respectively.

The Company currently estimates that, as a result of ongoing discussions, pending tax settlements and expirations of statutes of limitations, the amount of unrecognized tax benefits could be reduced by approximately $8 million during the next 12 months.

The Organization for Economic Cooperation and Development has proposed a 15% global minimum tax applied on a country-by-country basis (the "Pillar Two rule"), and many countries, including countries in which we operate, have enacted or begun the process of enacting laws adopting the Pillar Two rule. The first component of the Pillar Two rule became effective as of January 1, 2024, and did not have a material impact on the Company’s effective tax rate. With the DS Smith acquisition on January 31, 2025, the evaluation of the impact of the second component of Pillar Two is ongoing but is not expected to have a material impact on the Company's effective tax rate for 2025.

COMMITMENTS AND CONTINGENCIES (Note)

Commitments and Contingencies Disclosure [Abstract]

Commitments and Contingencies [Note Text Block]

General

The Company is involved in various inquiries, administrative proceedings and litigation relating to environmental and safety matters, personal injury, product liability, labor and employment, contracts, sales of property, intellectual property, tax, and other matters, that arise in the normal course of business. These matters may raise difficult and complicated legal issues and may be subject to many uncertainties and complexities. Moreover, some of these matters allege substantial or indeterminate monetary damages.

International Paper reviews inquiries, administrative proceedings and litigation, including with respect to environmental matters, on an ongoing basis and establishes an estimated liability for specific legal proceedings and other loss contingencies when it determines that the likelihood of an unfavorable outcome is probable, and the amount of the loss can be reasonably estimated. In addition, if the likelihood of an unfavorable outcome with respect to material loss contingencies is reasonably possible and International Paper is able to determine an estimate of the possible loss or range of loss, whether in excess of a related accrued liability of where there is no accrued liability, International Paper will disclose the estimate of the possible loss or range of loss. When no amount in a range of loss is more likely than any other amount in the range, the low end of the range is used as the estimate of the possible loss. International Paper’s assessment of whether a loss is probable is based on management’s assessment of the ultimate outcome of the matter.

Assessments of lawsuits and claims and the estimates reflected herein, are subject to significant judgments about future events, rely heavily on estimates and assumptions, and are otherwise subject to significant known and unknown uncertainties. The matters underlying such estimates may change from time to time and actual losses may vary significantly from current estimates. Additionally, the estimated liability for loss contingencies does not include matters or losses that are not reasonably estimable and probable.

Based on information currently known to International Paper, management believes that loss contingencies arising from pending matters, including the matters described herein, will not have a material adverse effect on the consolidated financial position or liquidity of the Company. However, in light of the inherent uncertainties involved in such 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 materially adverse to the Company's results of operations or cash flows in any particular reporting period.

Environmental

The Company has been named as a potentially responsible party ("PRP") in environmental remediation actions under various U.S.federal and state laws, including the Comprehensive Environmental Response, Compensation and Liability Act of 1980, as amended ("CERCLA"). Many of these proceedings involve the cleanup of hazardous substances at large commercial landfills that received waste from many different sources. While joint and several liability is authorized under CERCLA and equivalent state laws, as a practical matter, liability for CERCLA cleanups is typically allocated among the many PRPs. There are other remediation costs typically associated with the cleanup of hazardous substances at the Company’s current, closed and formerly-owned facilities, and recorded as liabilities in the balance sheet.

Remediation costs are recorded in the consolidated financial statements when they become probable and reasonably estimable. International Paper has estimated the probable liability associated with these environmental remediation matters, including those described herein, to be approximately $284 million and $279 million in the aggregate as of March 31, 2025 and December 31, 2024, respectively.

Cass Lake: One of the matters included above arises out of a closed wood-treatment facility located in Cass Lake, Minnesota. In June 2011, the U.S. Environmental Protection Agency ("EPA") selected and published a proposed soil remedy at the site. In April 2020, the EPA issued a final plan concerning clean-up standards at a portion of the site. The Company is performing RA and continues to cooperate with the EPA on the remaining remediation goals at the site. The estimated liability for the Cass Lake superfund site was $48 million as of both March 31, 2025 and December 31, 2024.

Kalamazoo River: The Company is a PRP with respect to the Allied Paper, Inc./Portage Creek/Kalamazoo River Superfund Site in Michigan. The EPA asserts that the site is contaminated by polychlorinated biphenyls primarily as a result of discharges from various paper mills located along the Kalamazoo River, including a paper mill formerly owned by St. Regis Paper Company ("St. Regis"). The Company is a successor in interest to St. Regis.

•Operable Unit 5, Area 1: In March 2016, the Company received a special notice letter from the EPA (i) inviting participation in implementing a remedy for a portion of the site known as Operable Unit 5 ("OU5"), Area 1, and (ii) demanding reimbursement of EPA past costs totaling $37 million. In December 2016, the EPA issued a unilateral administrative order ("UAO") to the Company and other PRPs to perform the remedy. The Company responded to the UAO, agreeing to comply with the order subject to its sufficient cause defenses. The Company continues to comply with the UAO in performing remediation activities at OU5, Area 1.

•Operable Unit 1 ("OU1"): In October 2016, the Company and another PRP received a special notice letter from the EPA inviting participation in the remedial design ("RD") component of the landfill remedy for the Allied Paper Mill, which is also known as Operable Unit 1. A Record of Decision ("ROD") establishing the final landfill remedy for the Allied Paper Mill was issued by the EPA in September 2016. The Company responded to the Allied Paper Mill special notice letter in December 2016 denying liability for OU1. In 2021, the EPA initiated RA activities. In October 2022, the Company received a unilateral administrative order to perform the RA. The Company began performing the RA in 2023 and established a $27 million reserve to account for this liability in the fourth quarter of 2022. In the fourth quarter of 2024, the Company increased the reserve by $27 million to account for the reasonably estimable costs for the next phases of the RA, following an EPA approved design modification in October to the original remedial design.

The total reserve for the combined liabilities for OU5, Area 1 and OU1 at the Kalamazoo River superfund site was $29 million as of both March 31, 2025 and December 31, 2024.

The Company was named as a defendant by Georgia-Pacific Consumer Products LP, Fort James Corporation and Georgia Pacific LLC (collectively, "GP") in a contribution and cost recovery action for alleged pollution at the site related to the Company's potential CERCLA liability. NCR Corporation and Weyerhaeuser Company were also named as defendants. The lawsuit seeks contribution under CERCLA for costs purportedly expended by plaintiffs ($79 million as of the filing of the complaint) and for future remediation costs. In June 2018, the District Court issued its Final Judgment and Order, which fixed the past cost amount at approximately $50 million (plus interest to be determined) and allocated to the Company a 15% share of responsibility for those past costs. The District Court did not address responsibility for future costs in its decision. In July 2018, the Company and each of the other parties filed notices appealing the Final Judgment and prior orders incorporated into the Final Judgment. In April 2022, the Sixth Circuit Court of Appeals (the "Sixth Circuit") reversed the Final Judgment of the Court, finding that the lawsuit against the Company was time-barred by the applicable statute of limitations. In May 2022, GP filed a petition for rehearing with the Sixth Circuit, which was denied in July 2022. In November 2022, GP filed a petition for writ of certiorari with the U.S. Supreme Court. In October 2023, the U.S. Supreme Court denied GP's writ petition, thus rendering final the Sixth Circuit's decision that GP's lawsuit against the Company was time-barred. In January 2024 GP requested that the District Court’s final order declare that each party is jointly and severally liable for future costs, arguing that the Sixth Circuit decision only applies to past costs. On April 9, 2024, the District Court entered Final Judgment After Remand, declaring, consistent with the Sixth Circuit's decision, that GP’s past costs are time-barred by the applicable statute of limitations. The District Court also entered Final Judgment on Remand that all three parties, including the Company, are jointly and severally liable for future response costs at the site. The Company believes the District Court’s Final Judgment on Remand regarding liability for future costs is in error and has appealed the Final Judgment on Remand on future costs liability to the Sixth Circuit.

Harris County: International Paper and McGinnis Industrial Maintenance Corporation ("MIMC"), a subsidiary of Waste Management, Inc. ("WMI"), are PRPs at the San Jacinto River Waste Pits Superfund Site in Harris County, Texas. The PRPs have been actively participating in the activities at the site and share the costs of these activities.

In October 2017, the EPA issued a ROD selecting the final remedy for the site: removal and relocation of the waste material from both the northern and southern impoundments.

In April 2018, the PRPs entered into an Administrative Order on Consent ("AOC") with the EPA, agreeing to work together to develop the RD for the northern impoundment. The AOC does not include any agreement to perform waste removal or other construction activity at the site.

In 2020, the Company reserved the following estimated liability amounts in relation to remediation at this site: (a) $10 million for the southern impoundment; and (b) $55 million for the northern impoundment, which represented the Company's 50% share of our estimate of the low end of the range of probable remediation costs.

The Company submitted the Final Design Package for the southern impoundment to the EPA, and the EPA approved the plan in May 2021. The EPA issued a Unilateral Administrative Order for RA of the southern impoundment in August 2021. An

addendum to the Final 100% RD (Amended April 2021) was submitted to the EPA for the southern impoundment in June 2022. The Company substantially completed the RA for the southern impoundment in 2024.

With respect to the northern impoundment, the PRPs submitted a Final 100% RD to EPA in July 2024. EPA provided comments at the end of October and a Revised Final 100% RD was submitted at the end of November 2024. The total estimated liability for the southern and northern impoundment was $98 million as of both March 31, 2025 and December 31, 2024. The current reserve is primarily for the Company’s 50% share of our estimate of the low end of the range of probable costs to implement the RD. Because of ongoing questions regarding cost effectiveness, timing and gathering other technical data, additional losses in excess of our recorded liability are possible.

Versailles Pond: The Company is a responsible party for the investigation and remediation of Versailles Pond, a 57-acre dammed river impoundment that historically received paperboard mill wastewater in Sprague, Connecticut. A comprehensive investigation has determined that Versailles Pond is contaminated with polychlorinated biphenyls, mercury, and metals. A preliminary remediation plan was prepared in the third quarter of 2023. Negotiations with state and federal governmental officials are ongoing regarding the scope and timing of the remediation. The total estimated liability for Versailles Pond was $29 million and $30 million as of March 31, 2025 and December 31, 2024,

Asbestos-Related Matters

We have been named as a defendant in various asbestos-related personal injury litigation, in both U.S. state and federal court, primarily in relation to the prior operations of certain companies previously acquired by the Company. The Company's total recorded liability with respect to pending and future asbestos-related claims was $100 million net of insurance recoveries as of both March 31, 2025 and December 31, 2024. While it is reasonably possible that the Company may incur losses in excess of its recorded liability with respect to asbestos-related matters, we are unable to estimate any loss or range of loss in excess of such liability, and do not believe additional material losses are probable.

Antitrust

In March 2017, the Italian Competition Authority ("ICA") commenced an investigation into the Italian packaging industry to determine whether producers of corrugated sheets and boxes violated the applicable European competition law. In April 2019, the ICA concluded its investigation and issued initial findings alleging that over 30 producers, including our Italian packaging subsidiary ("IP Italy") and, prior to completion of the business combination certain subsidiaries of DS Smith operating in Italy ("DS Smith Italy"), improperly coordinated the production and sale of corrugated sheets and boxes. In August 2019, the ICA issued its decision and assessed IP Italy a fine of €29 million (approximately $31 million at the then-current exchange rates) for participation in the boxes coordination, which was recorded in the third quarter of 2019. We appealed the ICA decision, and our appeal was denied in May 2021. We further appealed the decision to the Italian Council of State ("Council of State"), and in March 2023 the Council of State largely upheld the ICA’s findings, but referred the calculation of IP Italy’s fine back to the ICA, finding that it was disproportionately high based on the conduct found. Given the failure of the Council of State to address certain arguments brought by IP, we further appealed the Council of State decision to uphold the ICA’s findings. In March 2024, the Council of State published its decision holding that its earlier decision should be interpreted as accepting many of IP Italy’s earlier arguments and that the ICA should reduce IP Italy’s fine accordingly. Notwithstanding these decisions by the Council of State, in March 2024 the ICA served IP Italy with its redetermination decision leaving IP Italy’s fine unchanged. IP appealed the ICA's redetermination decision as inconsistent with the Council of State's 2024 and 2023 decision. In July 2024, the Council of State partially annulled the ICA redetermination decision, reducing IP Italy's fine by $6 million (€6 million). As of March 31, 2025, after giving effect to this development, the Company did not have any remaining liability related to IP Italy's fine. IP Italy has further appealed the Council of State's July 2024 decision seeking further reduction. DS Smith Italy was also subject to the ICA decision but not fined, given its position as leniency applicant. IP Italy, DS Smith Italy, and other producers also have been named in lawsuits, and we have received other claims, by a number of customers for damages associated with the alleged anticompetitive conduct. Given the early stages of these claims and the intention of the Company to defend robustly against such claims, it is too early to predict with any real degree of certainty, the precise overall outcome and ultimate potential liability (if any) that might be incurred in connection therewith, and there can be no guarantee that the aggregate of possible damages against IP Italy and DS Smith Italy could not, together, have a material impact on the Company’s financial condition.

Guarantees

In connection with sales of businesses, property, equipment, forestlands and other assets, International Paper commonly makes representations and warranties relating to such businesses or assets, and may agree to indemnify buyers with respect to tax and environmental liabilities, breaches of representations and warranties, and other matters. Where liabilities for such matters are

determined to be probable and reasonably estimable, accrued liabilities are recorded at the time of sale as a cost of the transaction.

Brazil Goodwill Tax Matter: The Brazilian Federal Revenue Service has challenged the deductibility of goodwill amortization generated in a 2007 acquisition by Sylvamo do Brasil Ltda. ("Sylvamo Brazil"), which was a wholly owned subsidiary of the Company until the October 1, 2021 spin-off of the Printing Papers business, after which it became a subsidiary of Sylvamo Corporation ("Sylvamo"). Sylvamo Brazil received assessments for the tax years 2007-2015 totaling approximately $103 million (adjusted for variation in currency exchange rates) in tax, plus interest, penalties and fees. The interest, penalties and fees currently total approximately $260 million (adjusted for variation in currency exchange rates). Accordingly, the assessments currently total approximately $363 million (adjusted for variation in currency exchange rates). After an initial favorable ruling challenging the basis for these assessments, Sylvamo Brazil received subsequent unfavorable decisions from the Brazilian Administrative Council of Tax Appeals. Sylvamo Brazil appealed these decisions. On October 11, 2024, the federal regional court issued a ruling favorable to Sylvamo Brazil in the first stage of judicial review on the assessments for tax years 2007 and 2008-2012, comprising approximately $230 million of the total $363 million as of March 31, 2025. On December 18, 2024, the Brazilian Federal Revenue Service appealed this ruling. This tax litigation matter may take many years to resolve. Sylvamo Brazil and International Paper believe the transaction underlying these assessments was appropriately evaluated, and that Sylvamo Brazil's tax position should be sustained, based on Brazilian tax law.

This matter pertains to a business that was conveyed to Sylvamo on October 1, 2021, as part of our spin-off transaction. Pursuant to the terms of the tax matters agreement entered into between the Company and Sylvamo, the Company will pay 60% and Sylvamo will pay 40%, on up to $300 million of any assessment related to this matter, and the Company will pay all amounts of the assessment over $300 million. Under the terms of the tax matters agreement, decisions concerning the conduct of the litigation related to this matter, including strategy, settlement, pursuit and abandonment, will be made by the Company. Sylvamo thus has no control over any decision related to this ongoing litigation. The Company intends to vigorously defend this historical tax position against the current assessments and any similar assessments that may be issued for tax years subsequent to 2015. The Brazilian government may enact a tax amnesty program that would allow Sylvamo Brazil to resolve this dispute for less than the assessed amount. As of October 1, 2021, in connection with the recording of the distribution of assets and liabilities resulting from the spin-off transaction, the Company established a liability representing the initial fair value of the contingent liability under the tax matters agreement. The contingent liability was determined in accordance with ASC 460 "Guarantees" based on the probability weighting of various possible outcomes. The initial fair value estimate and recorded liability as of December 31, 2021 was $48 million and remains this amount at March 31, 2025. This liability will not be increased in subsequent periods unless facts and circumstances change such that an amount greater than the initial recognized liability becomes probable and estimable.

Debt Disclosure [Abstract]

Debt [Note Text Block]

The borrowing capacity of the Company's commercial paper program is $1.0 billion supported by its $1.4 billion credit agreement. Under the terms of the program, individual maturities on borrowings may vary, but not exceed one year from the date of issue. Interest bearing notes may be issued either as fixed or floating rate notes. During the first quarter of 2025, the Company borrowed, and had outstanding, $175 million under the program.

At March 31, 2025, International Paper’s USD denominated credit facilities totaled $1.9 billion. The credit facilities generally provide for interest rates at a floating rate index plus a pre-determined margin dependent upon International Paper’s credit rating. The credit facilities included a $1.4 billion contractually committed bank facility with a maturity date of June 2028. The liquidity facilities also include up to $500 million of uncommitted financings based on eligible receivables balances under a receivables securitization program that expires in June 2025. At March 31, 2025, the Company had no borrowings outstanding under the receivables securitization program.

Following the DS Smith acquisition, International Paper assumed foreign denominated debt in various currencies with an approximated value of $3.6 billion. The assumed foreign credit facilities include a £1.25 billion contractually committed bank facility, a €200 million credit facility, a €60 million committed credit facility and a £50 million uncommited bank facility. The £1.25 billion contractually committed credit facility has a May 2027 maturity date. In March 2025, the Company amended and restated its credit facility agreement to, among other things (i) replace its obligation to prepare audited and unaudited consolidated accounts and instead provide International Paper’s account information, on the same terms as International Paper’s existing credit facilities, (ii) amend the financial covenant in the credit facility agreement to align with financial covenants given by International Paper in its existing credit facilities, (iii) amend certain events of default, and undertakings to align more closely with certain equivalent provisions included in the documentation relating to the existing financings of International Paper and to allow additional flexibility for potential reorganization of DS Smith’s subsidiaries, if required, now that DS Smith and its subsidiaries are part of the International Paper group. The multi-currency credit facility allows for GBP, EUR and USD borrowings and provides for interest rates at a floating rate index plus a pre-determined margin. Credit facility borrowings are denominated in the currency that aligns with the Company's cashflows. At March 31, 2025, the Company had $909 million outstanding under this facility.

At March 31, 2025, the Company had €200 million borrowings outstanding under the €200 million credit facility agreement with maturity dates from June 2025 through March 2029. In April 2025, the Company amended and restated this credit facility agreement to, among other things (i) replace its obligation to prepare audited and unaudited consolidated accounts and instead provide International Paper’s account information, on the same terms as International Paper’s existing credit facilities, (ii) amend the financial covenant in the credit facility agreement to align with financial covenants given by International Paper in its existing credit facilities, (iii) amend certain events of default, and undertakings to align more closely with certain equivalent provisions included in the documentation relating to the existing financings of International Paper and to allow additional flexibility for potential reorganization of DS Smith’s subsidiaries, if required, now that DS Smith and its subsidiaries are part of the International Paper group. The credit facility agreement provides for interest rates at a fixed rate. The Company’s credit facility agreement is not subject to any restrictive covenants other than that International Paper must comply with the same negative covenants as per its existing credit facilities.

The Company's €60 million committed bank facility matures in December 2026. In April 2025, the Company amended and restated this credit facility agreement to, among other things (i) replace its obligation to prepare audited and unaudited consolidated accounts and instead provide International Paper’s account information, on the same terms as International Paper’s existing credit facilities, (ii) amend the financial covenant in the credit facility agreement to align with financial covenants given by International Paper in its existing credit facilities, (iii) amend certain events of default, and undertakings to align more closely with certain equivalent provisions included in the documentation relating to the existing financings of International Paper and to allow additional flexibility for potential reorganization of DS Smith’s subsidiaries, if required, now that DS Smith and its subsidiaries are part of the International Paper group. The multi-currency credit facility allows for GBP, EUR and USD borrowings. At March 31, 2025, there were no borrowings outstanding under this agreement.

The Company has a £50 million uncommitted bank facility. At March 31, 2025 the Company had $63 million of translated borrowings outstanding under this agreement with no capacity remaining.

During the first quarter of 2025, the Company borrowed a USD equivalent $64 million under these foreign denominated credit facilities.

In the first quarter of 2025, International Paper entered into agreements to guarantee the outstanding notes of DS Smith. This included €600 million 0.8750% Notes due September 12, 2026; €850 million 4.375% Notes due July 27, 2027; £250 million 2.875% Notes due July 26, 2029; and €650 million 4.500% Notes due July 27, 2030.

At March 31, 2025, contractual obligations for future payments of debt maturities (including finance lease liabilities disclosed in Note 10 - Leases and excluding the timber monetization structure disclosed in Note 14 - Variable Interest Entities) by calendar year were as follows: $428 million in 2025; $905 million in 2026; $2.3 billion in 2027; $717 million in 2028; $344 million in 2029 and $4.9 billion thereafter.

The Company’s financial covenants require the maintenance of a minimum net worth, as defined in our debt agreements, of $9 billion and a total debt-to-capital ratio of less than 60%. Net worth is defined as the sum of common stock, paid-in capital and retained earnings, less treasury stock plus any cumulative goodwill impairment charges. The calculation also excludes accumulated other comprehensive income/loss and both the current and long-term Nonrecourse Financial Liabilities of Variable Interest Entities. The total debt-to-capital ratio is defined as total debt divided by the sum of total debt plus net worth. As of March 31, 2025, we were in compliance with our debt covenants.

At March 31, 2025, the fair value of International Paper’s $9.6 billion of debt was approximately $9.3 billion. The fair value of the Company’s long-term debt is estimated based on the quoted market prices for the same or similar issues. International Paper’s long-term debt is classified as Level 2 within the fair value hierarchy, which is further defined in Note 1 in the Company’s Annual Report.

Derivative Instruments and Hedging Activities

Derivative Instruments and Hedging Activities Disclosure [Abstract]

Derivative Instruments and Hedging Activities Disclosure

NOTE 16 - DERIVATIVES AND HEDGING ACTIVITIES

As a multinational company, International Paper is exposed to market risks, such as changes in interest rates, currency exchange rates and commodity prices.

International Paper periodically uses derivatives and other financial instruments to hedge exposures to interest rate, commodity and currency risks. International Paper does not hold or issue financial instruments for trading purposes. For hedges that meet the hedge accounting criteria at inception, International Paper formally designates and documents the instrument as a fair value hedge, a cash flow hedge or a net investment hedge of a specific underlying exposure.

Derivative and Hedging Accounting Policy

The Company and its subsidiaries are exposed to certain risks relating to its ongoing financial arrangements. The Company uses derivative financial instruments, primarily commodity swaps and forward contracts, to manage currency and commodity risks associated with the Company’s underlying business activities and the financing of these activities. As a matter of policy, we do not use financial instruments for speculative purposes.

ASC 815 requires entities to recognize all derivative instruments as either assets or liabilities in the statement of financial position at fair value. The accounting for changes in the fair value (i.e., gains or losses) of a derivative instrument depends on whether it has been designated and qualifies as part of a hedge accounting relationship and, further, on the type of hedge accounting relationship.

For those derivative or nonderivative instruments that are designated and qualify as hedging instruments under ASC 815, a company must designate the hedging instrument, based upon the exposure being hedged, as a fair value hedge, cash flow hedge, or a net investment hedge.

Gains or losses on cash flow hedges are deferred as a component of AOCI or losses and are reclassified into earnings at the time the hedged item affects earnings, presented in the same income statement line item as the underlying hedged item (i.e., in “cost of products sold” when the hedged transactions are commodity cash flows associated with energy purchases to facilitate operations). If it becomes probable that a forecasted transaction will not occur, previously deferred gains and losses related to those forecasted transactions would be recognized in earnings in the current period.

Gains and losses on net investment hedges are recorded in the cumulative translation adjustment component of AOCI, offsetting the translation adjustment of the net investment being hedged. Any deferred gains or losses previously recorded in the cumulative translation adjustment component of AOCI will remain in AOCI until the hedged net investment is sold or

substantially liquidated, at which time the cumulative deferred gains or losses are reclassified into earnings as a component of gain or loss on the sale of the hedged net investment.

To qualify for hedge accounting, a specified level of hedge effectiveness between the hedging instrument and the item being hedged must be achieved at inception and maintained throughout the hedged period. We formally document our risk management objectives, our strategies for undertaking the hedge transactions, the nature of and relationships between the hedging instruments and hedged items, and the method for assessing hedge effectiveness. Additionally, for qualified hedges of forecasted transactions, we specifically identify the significant characteristics and expected terms of the forecasted transactions.

Our designated derivative contracts include commodity swap contracts and forward contracts. Commodity swap contracts effectively modify the Company’s exposure to changes in natural gas and electricity prices by allowing the Company to purchase energy on a fixed-rate basis. Forward contracts effectively modify the Company’s exposure to fluctuations in the cost of carbon credits by allowing the Company to purchase carbon credits on a fixed-rate basis. These agreements involve the receipt of floating-rate amounts in exchange for fixed-rate amounts over the life of the agreements.

Commodity Risk Management

The Company has entered into commodity swap and commodity forward contracts which have been designated as cash flow hedges of commodity price risk associated with forecasted purchases and sales of various commodities used in the Company’s operations. These commodity contracts are used to manage exposure to changes in natural gas, electricity, and carbon credit prices. Individual commodity contracts are entered into up to three years prior to the occurrence of the hedged transactions.

Foreign Currency Risk Management

The Company and its subsidiaries periodically use non-derivative, foreign currency denominated loans to hedge the Company’s foreign currency exposure related to the translation of its net investment in foreign subsidiaries. Certain of these loans are designated as net investment hedges.

The component of the gains and losses on our net investment in these designated foreign operations, driven by changes in foreign exchange rates, are economically offset by remeasurements of our foreign-currency denominated debt.

The notional amounts of financial instruments used in hedging transactions were as follows:

In millions	March 31, 2025		December 31, 2024
Derivatives in Cash Flow Hedging Relationships:
Electricity contract (MWh)	0.7		—
Natural gas contracts (MWh)	6.2		—
Carbon credit contracts (tons)	0.7		—
Derivatives in Net Investment Hedging Relationships:
External debt (EUR)	€	3,198	€	—
Derivatives Not Designated as Hedging Instruments:

In millions	2025		2024
Derivatives in Cash Flow Hedging Relationships:
Commodity contacts	$	(52)	$	—
Derivatives in Net Investment Hedging Relationships:

Based on our valuation at March 31, 2025, and assuming market rates remain constant through contract maturities, we expect transfers to earnings of the existing gain or losses reported in AOCI on cash flow hedges during the next 12 months to correspond with the current assets and liabilities portion of the derivative as disclosed below.

Fair Value Measurements

The Company has not changed its valuation techniques for measuring the fair value of any financial assets or liabilities during the year. Transfers between levels, if any, are recognized at the end of the reporting period. International Paper’s derivatives are classified as Level 2 within the fair value hierarchy. Fair value hierarchies are further defined in Note 1 in the Company’s Annual Report.

The following table provides a summary of the impact of our derivative instruments in the balance sheet:

 

	Assets						Liabilities

(b)Includes $3 million recorded in Other current assets in the accompanying condensed consolidated balance sheet.

(c)Includes $64 million recorded in Other current liabilities and $16 million recorded in Other liabilities in the accompanying condensed consolidated balance sheet.

The above contracts are subject to enforceable master netting arrangements that provide rights of offset with each counterparty when amounts are payable on the same date in the same currency or in the case of certain specified defaults. Management has made an accounting policy election to not offset the fair value of recognized derivative assets and derivative liabilities in the balance sheet. The amounts owed to the counterparties and owed to the Company are considered immaterial with respect to each counterparty and in the aggregate with all counterparties.

Retirement Benefits [Abstract]

Retirement Plans [Note Text Block]

International Paper operates both defined benefit and defined contribution pension plans as well as other post retirement benefit plans throughout our operations in accordance with local conditions and practice.

We sponsor and maintain the Retirement Plan of International Paper Company (the "Pension Plan"), a tax-qualified defined benefit pension plan that provides retirement benefits to substantially all hourly and union employees who work at a participating business unit. The Pension Plan was frozen as of January 1, 2019 for salaried participants.

The Pension Plan provides defined pension benefits based on years of credited service and either final average earnings (salaried employees and hourly employees receiving salaried benefits), hourly job rates or specified benefit rates (hourly and union employees).

In connection with our acquisition, International Paper acquired the existing DS Smith Group Pension plan (the "Group Plan"), a UK funded defined benefit plan providing pension benefits and lump sum benefits to members and dependents. The Group Plan closed to new entrants and future accruals as of April 30, 2011.

Net periodic pension expense (income) for our qualified and nonqualified defined benefit plans and the Group Plan, comprised the following: 

	Three Months Ended March 31,
In millions	2025		2024
Service cost	$	10	$	13
Interest cost	124		111
Expected return on plan assets	(151)		(148)
Actuarial loss	18		19
Amortization of prior service cost	4		3
Settlement	8		—
Net periodic pension expense (income)	$	13	$	(2)

The components of net periodic pension expense (income) other than the Service cost component are included in Non-operating pension expense (income) in the condensed consolidated statement of operations.

The Company’s funding policy for our 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 plan, tax deductibility, the cash flows generated by the Company, and other factors. The Company made no voluntary cash contributions to the qualified pension plan in the first three months of 2025 or 2024. The nonqualified defined benefit plans are funded to the extent of benefit payments, which totaled $33 million and $5 million for the three months ended March 31, 2025 and 2024, respectively.

Share-Based Payment Arrangement [Abstract]

Share-based Payment Arrangement

International Paper's 2024 Long-term Incentive Compensation Plan (the "2024 LTICP') authorizes grants of restricted stock, restricted or deferred stock units, performance awards payable in cash or stock upon the attainment of specified performance goals, dividend equivalents, options, stock appreciation rights, other stock-based awards and cash-based awards at the discretion of the Management Development and Compensation Committee of the Board of Directors (the “MDCC”). On December 9, 2024, the MDCC approved the 2025 Long-Term Incentive Plan (the "2025 LTIP"), pursuant to the 2024 LTICP, approving a sole performance metric of 100% relative total shareholder return ("TSR") for performance stock unit awards, effective January 1, 2025. As of March 31, 2025, 7.0 million shares were available for grant under the LTICP.

Subsequent to the acquisition of DS Smith, the Company agreed to provide equity transition awards to DS Smith employees who became employees of the Company after closing of the transaction. The transition awards, which were granted in March 2025, consisted of time-based restricted stock units. The transition awards replaced the unvested portion of the 2024 DS Smith Performance Share Plan award granted to DS Smith employees in July 2024.

Stock-based compensation expense and related income tax benefits were as follows: 

	Three Months Ended March 31,

At March 31, 2025, $150 million, net of estimated forfeitures, of compensation cost related to time-based and performance-based shares and restricted stock attributable to future service had not yet been recognized. This amount will be recognized in expense over a weighted-average period of 1.9 years.

During the first three months of 2025, the Company granted 1.0 million performance units at an average grant date fair value of $66.30 and 0.9 million time-based units at an average grant date fair value of $54.17.

As a result of the completed acquisition of DS Smith on January 31, 2025, the CODM now reviews and manages the financial results and operations of the following segments on the basis of the new organizational structure, Packaging Solutions North America, Packaging Solutions EMEA and Global Cellulose Fibers. The Packaging Solutions EMEA segment includes the Company's legacy EMEA Industrial Packaging business and the newly acquired EMEA DS Smith business. As such, amounts related to the Company's legacy EMEA Industrial Packaging business have been recast out of the Industrial Packaging segment into the new Packaging Solutions EMEA segment for all prior periods. The newly acquired North America DS Smith business has been included in the Packaging Solutions North America segment. Amounts related to the Company's legacy North America Industrial Packaging business have been reported in the Packaging Solutions North America segment for all prior periods.

Packaging Solutions North America and Packaging Solutions EMEA are primarily focused on producing fiber-based packaging. We produce linerboard, medium, whitetop, recycled linerboard, recycled medium and saturating kraft of which a majority of our production is converted into corrugated packaging and other packaging. The revenue for our Packaging Solutions North America and Packaging Solutions EMEA segments are derived from selling these products to our customers.

Global Cellulose Fibers primarily focuses on producing cellulose fibers which is a renewable raw material used in a variety of products people depend on every day such as diapers, towel and tissue products, feminine care, incontinence and other personal care products. In addition, our innovative specialty pulps serve as a sustainable raw material used in textiles, construction materials, paints, coatings and more. The revenue for our Global Cellulose Fibers segment is derived from selling these products to our customers.

The CODM assesses performance for these segments and decides how to allocate resources based on business segment operating profit. Business segment operating profits (losses) are also used by International Paper's CODM to measure the earnings performance of its businesses and to focus on on-going operations.

Derivative Instruments and Hedging Activities Disclosure [Abstract]

Derivatives, Policy

Derivative and Hedging Accounting Policy

The Company and its subsidiaries are exposed to certain risks relating to its ongoing financial arrangements. The Company uses derivative financial instruments, primarily commodity swaps and forward contracts, to manage currency and commodity risks associated with the Company’s underlying business activities and the financing of these activities. As a matter of policy, we do not use financial instruments for speculative purposes.

ASC 815 requires entities to recognize all derivative instruments as either assets or liabilities in the statement of financial position at fair value. The accounting for changes in the fair value (i.e., gains or losses) of a derivative instrument depends on whether it has been designated and qualifies as part of a hedge accounting relationship and, further, on the type of hedge accounting relationship.

For those derivative or nonderivative instruments that are designated and qualify as hedging instruments under ASC 815, a company must designate the hedging instrument, based upon the exposure being hedged, as a fair value hedge, cash flow hedge, or a net investment hedge.

Gains or losses on cash flow hedges are deferred as a component of AOCI or losses and are reclassified into earnings at the time the hedged item affects earnings, presented in the same income statement line item as the underlying hedged item (i.e., in “cost of products sold” when the hedged transactions are commodity cash flows associated with energy purchases to facilitate operations). If it becomes probable that a forecasted transaction will not occur, previously deferred gains and losses related to those forecasted transactions would be recognized in earnings in the current period.

Gains and losses on net investment hedges are recorded in the cumulative translation adjustment component of AOCI, offsetting the translation adjustment of the net investment being hedged. Any deferred gains or losses previously recorded in the cumulative translation adjustment component of AOCI will remain in AOCI until the hedged net investment is sold or

substantially liquidated, at which time the cumulative deferred gains or losses are reclassified into earnings as a component of gain or loss on the sale of the hedged net investment.

To qualify for hedge accounting, a specified level of hedge effectiveness between the hedging instrument and the item being hedged must be achieved at inception and maintained throughout the hedged period. We formally document our risk management objectives, our strategies for undertaking the hedge transactions, the nature of and relationships between the hedging instruments and hedged items, and the method for assessing hedge effectiveness. Additionally, for qualified hedges of forecasted transactions, we specifically identify the significant characteristics and expected terms of the forecasted transactions.

Our designated derivative contracts include commodity swap contracts and forward contracts. Commodity swap contracts effectively modify the Company’s exposure to changes in natural gas and electricity prices by allowing the Company to purchase energy on a fixed-rate basis. Forward contracts effectively modify the Company’s exposure to fluctuations in the cost of carbon credits by allowing the Company to purchase carbon credits on a fixed-rate basis. These agreements involve the receipt of floating-rate amounts in exchange for fixed-rate amounts over the life of the agreements.
