Accounting Policies [Abstract]
Summary Of Business And Significant Accounting Policies	NOTE 1 SUMMARY OF BUSINESS AND SIGNIFICANT ACCOUNTING POLICIES NATURE OF BUSINESS International Paper (the "Company") is a global producer of renewable fiber-based packaging and pulp products with primary markets and manufacturing operations in North America and Europe and additional markets and manufacturing operations in Latin America, North Africa and Asia. Substantially all of our businesses have experienced, and are likely to continue to experience, cycles relating to available industry capacity and general economic conditions. FINANCIAL STATEMENTS These consolidated financial statements have been prepared in conformity with accounting principles generally accepted in the United States that require the use of management’s estimates. Actual results could differ from management’s estimates. Certain amounts from prior year have been reclassified to conform with the current year financial statement presentation. DISCONTINUED OPERATIONS A discontinued operation may include a component or a group of components of the Company's operations. A disposal of a component or a group of components is reported in discontinued operations if the disposal represents a strategic shift that has or will have a major effect on the Company's operations and financial results when the following occurs: (1) a component (or group of components) meets the criteria to be classified as held for sale; (2) the component or group of components is disposed of by sale; or (3) the component or group of components is disposed of other than by sale (for example, by abandonment or in a distribution to owners in a spin-off). For any component classified as held for sale or disposed of by sale or other than by sale, qualifying for presentation as a discontinued operation, the Company reports the results of operations of the discontinued operations (including any gain or loss recognized on the disposal or loss recognized on classification as held for sale of a discontinued operation), less applicable income taxes (benefit), as a separate component in the consolidated statement of operations for current and all prior periods presented. The Company also reports assets and liabilities associated with discontinued operations as separate line items on the consolidated balance sheet. The Company recorded discontinued operations for the years ended December 31, 2023 and 2022 in connection with the sale of its equity method investment in Ilim. See Note 10 for further details. CONSOLIDATION The consolidated financial statements include the accounts of International Paper and subsidiaries for which we have a controlling financial interest, including variable interest entities for which we are the primary beneficiary. All significant intercompany balances and transactions are eliminated. EQUITY METHOD INVESTMENTS The equity method of accounting is applied for investments when the Company has significant influence over the investee’s operations, or when the investee is structured with separate capital accounts. Our material equity method investments are described in Note 10 . OTHER-THAN-TEMPORARY IMPAIRMENT T he Company evaluates our equity method investments for other-than-temporary impairment ("OTTI") when circumstances indicate the investment may be impaired. When a decline in fair value is deemed to be an OTTI, an impairment is recognized to the extent that the fair value is less than the carrying value of the investment. We consider various factors in determining whether a loss in value of an investment is other than temporary including: the length of time and the extent to which the fair value has been below cost, the financial condition of the investee, and our intent and ability to retain the investment for a period of time sufficient to allow for recovery of value. Management makes certain judgments and estimates in its assessment including but not limited to: identifying if circumstances indicate a decline in value is other than temporary, expectations about operations, as well as industry, financial, regulatory and market factors. BUSINESS COMBINATIONS The Company allocates the total consideration 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 cash flows, anticipated growth rates, discount rates, 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 statement of operations. Subsequent actual results of the underlying business activity supporting the specifically identified intangible assets could change, requiring us to record impairment charges or adjust their economic lives in future periods. See Note 7 for further details. RESTRUCTURING LIABILITIES AND COSTS For operations to be closed or restructured, a liability and related expense is recorded in the period when operations cease. For termination costs associated with employees covered by a written or substantive plan, a liability is recorded when it is probable that employees will be entitled to benefits and the amount can be reasonably estimated. For termination costs associated with employees not covered by a written and broadly communicated policy covering involuntary termination benefits (severance plan), a liability is recorded for costs to terminate employees (one-time termination benefits) when the termination plan has been approved and committed to by management, the employees to be terminated have been identified, the termination plan benefit terms are communicated, the employees identified in the plan have been notified and actions required to complete the plan indicate that it is unlikely that significant changes to the plan will be made or that the plan will be withdrawn. The timing and amount of an accrual is dependent upon the type of benefits granted, the timing of communication and other provisions that may be provided in the benefit plan. The accounting for each termination is evaluated individually. See Note 6 for further details. REVENUE RECOGNITION Generally, the Company recognizes revenue on a point-in-time basis when the Company transfers control of the goods to the customer. 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. The Company’s revenue is primarily derived from fixed consideration; however, we do have contract terms that give rise to variable consideration, primarily volume rebates, early payment discounts and other customer refunds. The Company estimates its volume rebates at the individual customer level based on the most likely amount method outlined in ASC 606 "Revenue from Contracts with Customers". The Company estimates early payment discounts and other customer refunds based on the historical experience across the Company's portfolio of customers to record reductions in revenue that is consistent with the expected value method outlined in ASC 606. Management has concluded that these methods result in the best estimate of the consideration the Company will be entitled to from its customers. The Company has elected to present all sales taxes on a net basis, account for shipping and handling activities as fulfillment activities, recognize the incremental costs of obtaining a contract as expense when incurred if the amortization period of the asset the Company would recognize is one year or less, and not record interest income or interest expense when the difference in timing of control or transfer and customer payment is one year or less. See Note 3 for further details. TEMPORARY INVESTMENTS Temporary investments with an original maturity of three months or less and money market funds with greater than three-month maturities but with the right to redeem without notice are treated as cash equivalents and are stated at cost, which approximates market value. See Note 8 for further details. INVENTORIES Inventories include all costs directly associated with manufacturing products: materials, labor, and manufacturing overhead. In the United States, costs of raw materials and finished pulp and paper products are generally determined using the last-in, first-out method. These inventories are measured at the lower of cost or market. Other inventories are valued using the first-in, first-out or average cost methods. These inventories are measured at the lower of cost or net realizable value. See Note 8 for further details. LEASED ASSETS Operating lease right of use ("ROU") assets and liabilities are recognized at the commencement date of the lease based on the present value of lease payments over the lease term. The Company's leases may include options to extend or terminate the lease. These options to extend are included in the lease term when it is reasonably certain that we will exercise that option. Some leases have variable payments, however, because they are not based on an index or rate, they are not included in the ROU assets and liabilities. Variable payments for real estate leases primarily relate to common area maintenance, insurance, taxes and utilities. Variable payments for equipment, vehicles, and leases within supply agreements primarily relate to usage, repairs and maintenance. As the implicit rate is not readily determinable for most of the Company's leases, the Company applies a portfolio approach using an estimated incremental borrowing rate to determine the initial present value of lease payments over the lease terms on a collateralized basis over a similar term, which is based on market and company specific information. We use the unsecured borrowing rate and risk-adjust that rate to approximate a collateralized rate, and apply the rate based on the currency of the lease, which is updated on a quarterly basis for measurement of new lease liabilities. Leases having a lease term of twelve months or less are not recorded on the balance sheet and the related lease expense is recognized on a straight-line basis over the term of the lease. In addition, the Company has applied the practical expedient to account for the lease and non-lease components as a single lease component for all of the Company's leases except for certain gas and chemical agreements. See Note 9 for further details. PLANTS, PROPERTIES AND EQUIPMENT Plants, properties and equipment are stated at cost, less accumulated depreciation. Expenditures for betterments are capitalized, whereas normal repairs and maintenance are expensed as incurred. The units-of-production method of depreciation is used for pulp and paper mills, and the straight-line method is used for other plants and equipment. If a decision is made to abandon plants, properties or equipment before the end of its useful life, depreciation expense is revised to reflect the shortened useful life. See Note 8 for further details. GOODWILL Annual evaluation for possible goodwill impairment is performed as of the beginning of the fourth quarter of each year, with additional interim evaluation performed when management believes that it is more likely than not, that events or circumstances have occurred that would result in the impairment of a reporting unit’s goodwill. The Company has the option to evaluate goodwill for impairment by first performing a qualitative assessment of events and circumstances to determine whether it is more likely than not that the fair value of a reporting unit is less than its carrying amount. If, after assessing the totality of events or circumstances, the Company determines that it is not more likely than not that the fair value of a reporting unit is less than its carrying amounts, then the quantitative goodwill impairment test is not required to be performed. If the Company determines that it is more likely than not that the fair value of a reporting unit is less than its carrying amount, or if the Company does not elect the option to perform an initial qualitative assessment, the Company is required to perform the quantitative goodwill impairment test. In performing this evaluation, the Company estimates the fair value of its reporting unit using a weighted approach based on discounted future cash flows, market multiples and transaction multiples. The determination of fair value using the discounted cash flow approach requires management to make significant estimates and assumptions related to forecasts of future revenues, operating profit margins, and discount rates. The determination of fair value using market multiples and transaction multiples requires management to make significant assumptions related to revenue multiples and adjusted earnings before interest, taxes, depreciation, and amortization ("EBITDA") multiples. For reporting units whose carrying amount is in excess of their estimated fair value, the reporting unit will record an impairment charge by the amount that the carrying amount exceeds the reporting unit's fair value, not to exceed the total amount of goodwill allocated to the reporting unit. IMPAIRMENT OF LONG-LIVED ASSETS Long-lived assets are reviewed for impairment upon the occurrence of events or changes in circumstances that indicate that the carrying value of the assets may not be recoverable. A recoverability test is performed by comparing the undiscounted cash flows to carrying value of the assets. The inputs related to the undiscounted cash flows requires judgments as to whether assets are held and used or held for sale, the weighting of operational alternatives being considered by management and estimates of the amount and timing of expected future cash flows from the use of the long-lived assets generated by their use. If the carrying amount is less than the undiscounted cash flows, the fair value of the assets is compared to the carrying value to determine if they are impaired. We estimate fair value using discounted cash flows and other valuation techniques as needed. Impaired assets are recorded at their estimated fair value. INCOME TAXES International Paper uses the asset and liability method of accounting for income taxes whereby deferred income taxes are recorded for the future tax consequences attributable to differences between the financial statement and tax bases of assets and liabilities. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. Deferred tax assets and liabilities are remeasured to reflect new tax rates in the periods rate changes are enacted. International Paper records its global tax provision based on the respective tax rules and regulations for the jurisdictions in which it operates. Where the Company believes that a tax position is supportable for income tax purposes, the item is included in its income tax returns. Where treatment of a position is uncertain, liabilities are recorded based upon the Company’s evaluation of the “more likely than not” outcome considering technical merits of the position based on specific tax regulations and facts of each matter. Changes to recorded liabilities are only made when an identifiable event occurs that changes the likely outcome, such as settlement with the relevant tax authority, the expiration of statutes of limitation for the subject tax year, change in tax laws, or recent court cases that are relevant to the matter. Accrued interest related to these uncertain tax positions is recorded in our consolidated statement of operations in Interest expense, net. The judgments and estimates made by the Company are based on management’s evaluation of the technical merits of a matter, assisted as necessary by consultation with outside consultants, historical experience and other assumptions that management believes are appropriate and reasonable under current circumstances. Actual resolution of these matters may differ from recorded estimated amounts, resulting in adjustments that could materially affect future financial statements. See Note 12 for further details. Valuation allowances are recorded to reduce deferred tax assets when it is more likely than not that a tax benefit will not be realized. Significant judgment is required in assessing the need for and magnitude of appropriate valuation allowances against deferred tax assets. This assessment is completed by tax jurisdiction and relies on both positive and negative evidence available, with significant weight placed on recent financial results. Cumulative reported pre-tax income is considered objectively verifiable positive evidence of our ability to generate positive pre-tax income in the future. In accordance with GAAP, when there is a recent history of pre-tax losses, there is little or no weight placed on forecasts for purposes of assessing the recoverability of our deferred tax assets. When necessary, we use systematic and logical methods to estimate when deferred tax liabilities will reverse and generate taxable income and when deferred tax assets will reverse and generate tax deductions. Assumptions, judgment, and the use of estimates are required when scheduling the reversal of deferred tax assets and liabilities, and the exercise is inherently complex and subjective. The realization of these assets is dependent on generating future taxable income, as well as successful implementation of various tax planning strategies. International Paper uses the flow-through method to account for investment tax credits earned on eligible open-loop biomass facilities and combined heat and power system expenditures. Under this method, the investment tax credits are recognized as a reduction to income tax expense in the year they are earned rather than a reduction in the asset basis. ENVIRONMENTAL REMEDIATION COSTS Costs associated with environmental remediation obligations are accrued when such costs are probable and reasonably estimable. Such accruals are adjusted as further information develops or circumstances change. See Note 13 for further details. TRANSLATION OF FINANCIAL STATEMENTS Balance sheets of international operations are translated into U.S. dollars at year-end exchange rates, while statements of operations are translated at average rates. Adjustments resulting from financial statement translations are included as cumulative translation adjustments in Accumulated other comprehensive income (loss). FAIR VALUE MEASUREMENTS The guidance for fair value measurements and disclosures sets out a fair value hierarchy that groups fair value measurement inputs into the following three classifications: Level 1: Quoted market prices in active markets for identical assets or liabilities. Level 2: Observable market-based inputs other than quoted prices included within Level 1 that are observable for the asset or liability, either directly or indirectly. Level 3: Unobservable inputs for the asset or liability reflecting the reporting entity’s own assumptions or external inputs from inactive markets. Transfers between levels are recognized at the end of the reporting period.

Accounting Standards Update and Change in Accounting Principle [Abstract]
Recent Accounting Developments	NOTE 2 RECENT ACCOUNTING DEVELOPMENTS Other than as described below, no new accounting pronouncement issued or effective during the fiscal year has had or is expected to have a material impact on the consolidated financial statements. RECENTLY ADOPTED ACCOUNTING PRONOUNCEMENTS Reference Rate Reform In March 2020, the Financial Accounting Standards Board ("FASB") issued Accounting Standard Update ("ASU") 2020-04, "Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting." This guidance provides companies with optional guidance to ease the potential accounting burden associated with transitioning away from reference rates that are expected to be discontinued. This guidance is effective upon issuance and generally can be applied through December 31, 2024. The Company has applied this guidance to account for contract modifications due to changes in reference rates as those modifications occurred. This guidance has not had a material impact on our consolidated financial statements and related disclosures. Segment Reporting In November 2023, the FASB issued ASU 2023-07, "Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures." This guidance requires companies to disclose incremental segment information on an annual and interim basis. This guidance is effective for annual reporting periods beginning after December 15, 2023 and interim periods within those years beginning after December 15, 2024. Amendments are required to be applied retrospectively to all prior periods presented in the financial statements. The Company adopted this guidance as of January 1, 2024 which only impacted the related disclosure - see Note 20 - Financial Information by Business Segment and Geographic Area . 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 and should be applied prospectively. The Company is currently evaluating the provisions of this guidance. Income Taxes In December 2023, the FASB issued ASU 2023-09, "Income Taxes (Topic 740): Improvements to Income Tax Disclosures." This guidance requires 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 plans to adopt this guidance as of January 1, 2025 and will update disclosures within the Company's 2025 annual filing.

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. Current liabilities of $30 million and $32 million are included in Other current liabilities in the accompanying consolidated balance sheet as of December 31, 2024 and 2023, respectively. The Company also recorded a contract liability of $115 million related to a previous acquisition. The balance of this contract liability was $84 million and $92 million at December 31, 2024 and 2023, respectively, and is recorded in Other current liabilities and Other Liabilities in the accompanying 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 which we have an unconditional right to payment or receive prepayment from the customer, respectively. PERFORMANCE OBLIGATIONS AND SIGNIFICANT JUDGMENTS International Paper's principal business is to manufacture and sell fiber-based packaging and pulp goods. As a general rule, none of our businesses provide equipment installation or other ancillary services outside of producing and shipping packaging and pulp products to customers. The nature of the Company's contracts can vary based on the business, customer type and region; however, in all instances it is International Paper's customary business practice to receive a valid order from the customer, in which each parties' rights and related payment terms are clearly identifiable. Contracts or purchase orders with customers could include a single type of product or it could include multiple types/grades of products. Regardless, the contracted price with the customer is agreed to at the individual product level outlined in the customer contracts or purchase orders. The Company does not bundle prices; however, we do negotiate with customers on pricing and rebates for the same products based on a variety of factors (e.g. level of contractual volume, geographical location, etc.). Management has concluded that the prices negotiated with each individual customer are representative of the stand-alone selling price of the product.

Earnings Per Share [Abstract]
Earnings Per Share Attributable To International Paper Company Common Shareholders	NOTE 4 EARNINGS PER SHARE ATTRIBUTABLE TO INTERNATIONAL PAPER COMPANY COMMON SHAREHOLDERS 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 from continuing operations, and diluted earnings (loss) per share from continuing operations is as follows: In millions, except per share amounts 2024 2023 2022 Earnings (loss) from continuing operations attributable to International Paper common shareholders $ 557 $ 302 $ 1,741 Weighted average common shares outstanding 347.2 346.9 363.5 Effect of dilutive securities: Restricted performance share plan 7.0 2.2 3.5 Weighted average common shares outstanding – assuming dilution 354.2 349.1 367.0 Basic earnings (loss) per share from continuing operations $ 1.60 $ 0.87 $ 4.79 Diluted earnings (loss) per share from continuing operations $ 1.57 $ 0.86 $ 4.74

In connection with potential future closures or redesigns of certain production facilities, it is possible that the Company may be required to take steps to remove certain materials from these facilities. Applicable regulations and standards provide that the removal of certain materials would only be required if the facility were to be demolished or underwent major renovations. At this time, any such obligations have an indeterminate settlement date, and the Company believes that adequate information does not exist to apply an expected-present-value technique to estimate any such potential obligations. Accordingly, the Company does not record a liability for such remediation until a decision is made that allows reasonable estimation of the timing of such remediation.

Goodwill and Intangible Assets Disclosure [Abstract]
Goodwill And Other Intangibles	GOODWILL The following table presents changes in the goodwill balances as allocated to each reportable business segment for the years ended December 31, 2024 and 2023: In millions Industrial Global Cellulose Fibers Total Balance as of December 31, 2022 Goodwill $ 3,413 $ 52 $ 3,465 Accumulated impairment losses (372) (52) (424) 3,041 — 3,041 Balance as of December 31, 2023 Goodwill 3,413 52 3,465 Accumulated impairment losses (372) (52) (424) 3,041 — 3,041 Currency translation and other (a) (3) — (3) Balance as of December 31, 2024 Goodwill 3,410 52 3,462 Accumulated impairment losses (372) (52) (424) Total $ 3,038 $ — $ 3,038 (a) Represents the effects of foreign currency translations and reclassifications. The Company performed its annual goodwill impairment testing by applying the quantitative goodwill impairment test to its North America Industrial Packaging reporting unit as of October 1, 2024. This was performed by comparing the carrying amount of the North America Industrial Packaging reporting unit to its estimated fair value. The estimated fair value of the reporting unit was calculated using a weighted approach based on discounted future cash flows, market multiples and transaction multiples which are classified as Level 2 and Level 3 within the fair value hierarchy. The determination of fair value using the discounted cash flow approach requires management to make significant estimates and assumptions related to forecasts of future revenues, operating profit margins, and discount rates. The determination of fair value using market multiples and transaction multiples requires management to make significant assumptions related to revenue multiples and adjusted earnings before interest, taxes, depreciation, and amortization ("EBITDA") multiples. The results of our quantitative goodwill impairment test indicated that the carrying amount did not exceed the estimated fair value of the North America Industrial Packaging reporting unit. In the fourth quarter of 2022, the Company performed the quantitative goodwill impairment test related to its EMEA Industrial Packaging reporting unit and estimated fair value in the same manner noted above. The results of our quantitative goodwill impairment test indicated that the carrying amount exceeded the estimated fair value of the EMEA Industrial Packaging reporting unit and it was determined that all of the goodwill in the reporting unit, totaling $76 million, was impaired. The decline in the fair value of EMEA Industrial Packaging and resulting impairment charge was due to the impacts of certain negative macroeconomic conditions, including the impacts from inflation and the geopolitical environment to the reporting unit.

Income Taxes	The components of International Paper’s earnings from continuing operations before income taxes and equity earnings by taxing jurisdiction were as follows: In millions 2024 2023 2022 Earnings (loss) U.S. $ (140) $ 129 $ 1,469 Non-U.S. 287 253 42 Earnings (loss) from continuing operations before income taxes and equity earnings (losses) $ 147 $ 382 $ 1,511 The provision (benefit) for income taxes from continuing operations (excluding noncontrolling interests) by taxing jurisdiction was as follows: In millions 2024 2023 2022 Current tax provision (benefit) U.S. federal $ (4) $ 157 $ 454 U.S. state and local 20 16 56 Non-U.S. 42 42 27 $ 58 $ 215 $ 537 Deferred tax provision (benefit) U.S. federal $ (367) $ (164) $ (775) U.S. state and local (98) 3 (39) Non-U.S. (8) 5 41 $ (473) $ (156) $ (773) Income tax provision (benefit) $ (415) $ 59 $ (236) The Company’s deferred income tax provision (benefit) includes a $1 million expense, a $6 million benefit and an $3 million benefit for 2024, 2023 and 2022, respectively, for the effect of various changes in non-U.S. and U.S. federal and state tax rates. International Paper made income tax payments, net of refunds, of $394 million, $340 million and $345 million in 2024, 2023 and 2022, respectively. A reconciliation of income tax expense using the statutory U.S. income tax rate compared with the actual income tax provision follows: In millions 2024 2023 2022 Earnings (loss) from continuing $ 147 $ 382 $ 1,511 Statutory U.S. income tax rate 21 % 21 % 21 % Tax expense (benefit) using statutory U.S. income tax rate 31 80 317 State and local income taxes (62) 2 44 Impact of rate differential on non-U.S. permanent differences and earnings (26) (10) 1 Foreign valuation allowance — — 45 Tax expense (benefit) on exchange of Sylvamo shares — — (56) Non-taxable income (4) (2) (2) Non-deductible business expenses 21 7 2 Non-deductible impairments — — 16 Non-deductible compensation 8 7 13 Tax audits — (4) 6 Timber Monetization Audit Settlement — — (604) Foreign derived intangible income deduction — 2 (8) US tax on non-U.S. earnings (GILTI and Subpart F) 32 — 27 Foreign tax credits 7 8 8 General business and other tax credits (31) (38) (43) Tax expense (benefit) on equity earnings (1) (4) (1) Legal entity restructuring expense (benefit) (391) 4 — Other, net 1 7 (1) Income tax provision (benefit) $ (415) $ 59 $ (236) Effective income tax rate (282) % 15 % (16) % The tax effects of significant temporary differences, representing deferred income tax assets and liabilities at December 31, 2024 and 2023, were as follows: In millions 2024 2023 Deferred income tax assets: Postretirement benefit accruals $ 72 $ 67 Pension obligations 63 61 Tax credits 183 182 Net operating and capital loss carryforwards 1,181 699 Compensation reserves 224 146 Lease obligations 112 116 Environmental reserves 131 114 Investments 4 — Research and development expenditures 240 162 Other 203 157 Gross deferred income tax assets $ 2,413 $ 1,704 Less: valuation allowance (a) (1,201) (848) Net deferred income tax asset $ 1,212 $ 856 Deferred income tax liabilities: Intangibles $ (133) $ (141) Investments — 3 Right of use assets (112) (116) Plants, properties and equipment (1,528) (1,650) Forestlands, related installment sales, and investment in subsidiary (486) (485) Gross deferred income tax liabilities $ (2,259) $ (2,389) Net deferred income tax liability $ (1,047) $ (1,533) (a) The net change in the total valuation allowance for the years ended December 31, 2024 and 2023 was an increase of $353 million and a increase of $171 million, respectively. Deferred income tax assets and liabilities are recorded in the accompanying consolidated balance sheet under the captions Deferred charges and other assets and Deferred income taxes, respectively. The $486 million of deferred tax liabilities for forestl ands, related installment sales, and investment in subsidiary is attributable to a 2007 Temple-Inland installment sale of forestlands (see Note 14 - Variable Interest Entities ). During 2024, the Company completed an internal legal entity restructuring for which a capital loss was recognized for U.S. federal and state income tax purposes resulting in a tax benefit of $416 million. The Company intends to carry back a portion of the loss to prior years and has set up a non-current receivable in the amount of $279 million. The remaining capital loss will be carried forward to offset future capital gains, and, as such, the Company recorded a deferred tax asset in the amount of $137 million for the year ended December 31, 2024. A reconciliation of the beginning and ending amount of unrecognized tax benefits recorded in Other Liabilities in the accompanying consolidated balance sheet for the years ended December 31, 2024, 2023 and 2022 is as follows: In millions 2024 2023 2022 Balance at January 1 $ (173) $ (177) $ (166) (Additions) reductions for tax positions related to current year (10) (13) (7) (Additions) for tax positions related to prior years (40) (11) (10) Reductions for tax positions related to prior years 7 1 3 Settlements 4 17 1 Expiration of statutes of 6 11 1 Currency translation adjustment 2 (1) 1 Balance at December 31 $ (204) $ (173) $ (177) If the Company were to prevail on the unrecognized tax benefits recorded, substantially all of the balances at December 31, 2024, 2023 and 2022 would benefit the effective tax rate. Pending audit settlements and the expiration of statutes of limitation are not expected to reduce uncertain tax positions during the next twelve months. The Company accrues interest on unrecognized tax benefits as a component of interest expense. Penalties, if incurred, are recognized as a component of income tax expense. The Company had approximately $50 million and $34 million accrued for the payment of estimated interest and penalties associated with unrecognized tax benefits at December 31, 2024 and 2023, respectively. The Company is currently subject to audits in the United States and other taxing jurisdictions around the world. Generally, tax years 2012 through 2023 remain open and subject to examination by the relevant tax authorities. The Company frequently faces challenges regarding the amount of taxes due. These challenges include positions taken by the Company related to the timing, nature, and amount of deductions and the allocation of income among various tax jurisdictions. On September 3, 2024, the Company received the Unagreed Revenue Agent Report from the Internal Revenue Service relating to investment tax credits for the 2017-2019 years that currently are under examination. The estimated net incremental tax liability associated with the proposed adjustments would be approximately $50 million. The Company disagrees with the proposed adjustments and initiated the administrative appeals process on October 30, 2024 with the filing of our Protest of the proposed adjustments. An unfavorable resolution in the administrative appeals process or future tax litigation could result in cash tax payments and could adversely impact the effective tax rate. 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. The second component is expected to go into effect in 2025. The Company provides for foreign withholding taxes and any applicable U.S. state income taxes on earnings intended to be repatriated from non-U.S. subsidiaries, which we believe will be limited in the future to each year's current earnings. No provision for these taxes on approximately $1.1 billion of undistributed earnings of non-U.S. subsidiaries as of December 31, 2024 has been made, as these earnings are considered indefinitely invested. Determination of the amount of taxes that might be paid on these undistributed earnings if eventually remitted in a taxable manner is not practicable. If management decided to monetize the Company’s foreign investments, we would recognize the tax cost related to the excess of the book value over the tax basis of those investments. This would include foreign withholding taxes and any applicable U.S. Federal and state income taxes. Determination of the tax cost that would be incurred upon monetization of the Company’s foreign investments is not practicable; however, we do not believe it would be material. The following details the scheduled expiration dates of the Company’s net operating loss and income tax credit and capital loss carryforwards: In millions 2025 2035 Indefinite Total U.S. federal and non-U.S. NOLs $ 3 $ 603 $ 397 $ 1,003 State taxing jurisdiction NOLs (a) 28 9 — 37 U.S. federal, non- 73 14 96 183 U.S. federal and state capital loss carryforwards (a) 141 — — 141 Total $ 245 $ 626 $ 493 $ 1,364 Less: valuation allowance (a) (58) (612) (449) (1,119) Total, net $ 187 $ 14 $ 44 $ 245 (a) State amounts are presented net of federal benefit.

Commitments and Contingencies Disclosure [Abstract]
Commitments And Contingent Liabilities	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 AND LEGAL PROCEEDINGS Environmental The Company has been named as a potentially responsible party ("PRP") in environmental remediation actions under various 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 $279 million and $251 million in the aggregate as of December 31, 2024 and December 31, 2023, respectively. Other than as described below, completion of required environmental remedial actions ("RAs") is not expected to have a material effect on our consolidated financial statements. 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 and $46 million as of December 31, 2024 and December 31, 2023, respectively. 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 and $27 million as of December 31, 2024 and 2023, respectively. 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 and $83 million as of December 31, 2024 and 2023, respectively. 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 $30 million as of both December 31, 2024 and December 31, 2023. Asbestos-Related Matters We have been named as a defendant in various asbestos-related personal injury litigation, in both 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 and $97 million, both net of insurance recoveries as of December 31, 2024 and December 31, 2023, respectively. 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 December 31, 2024, 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 $95 million (adjusted for variation in currency exchange rates) in tax, plus interest, penalties and fees. The interest, penalties and fees currently total approximately $235 million (adjusted for variation in currency exchange rates). Accordingly, the assessments currently total approximately $330 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 $210 million of the total $330 million as of December 31, 2024. 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 December 31, 2024. 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 [Abstract]
Variable Interest Entities And Preferred Securities Of Subsidiaries	In connection with the acquisition of Temple-Inland in February 2012, two special purpose entities became wholly-owned subsidiaries of International Paper. The use of the two wholly-owned special purpose entities discussed below preserved the tax deferral that resulted from the 2007 Temple-Inland timberlands sales. As of December 31, 2024, this deferred tax liability was $486 million, which will be settled with the maturity of the notes in 2027. In October 2007, Temple-Inland sold 1.55 million acres of timberland for $2.4 billion. The total consideration consisted almost entirely of notes due in 2027 issued by the buyer of the timberland, which Temple-Inland contributed to two wholly-owned, bankruptcy-remote special purpose entities. The notes are shown in Long-term financial assets of variable interest entities in the accompanying consolidated balance sheet and are supported by $2.4 billion of irrevocable letters of credit issued by three banks, which are required to maintain minimum credit ratings on their long-term debt. In December 2007, Temple-Inland's two wholly-owned special purpose entities borrowed $2.1 billion which is shown in Long-term nonrecourse financial liabilities of variable interest entities. The loans are repayable in 2027 and are secured by the $2.4 billion of notes and the irrevocable letters of credit securing the notes, and are nonrecourse to us. The loan agreements provide that if a credit rating of any of the banks issuing the letters of credit is downgraded below the specified threshold, the letters of credit issued by that bank must be replaced within 30 days with letters of credit from another qualifying financial institution. As of both December 31, 2024 and 2023, the fair value of the notes receivable was $2.3 billion. As of both December 31, 2024 and 2023, the fair value of this debt was $2.1 billion. The notes receivable and debt are classified as Level 2 within the fair value hierarchy. Activity between the Company and the 2007 financing entities was as follows: In millions 2024 2023 2022 Revenue (a) $ 152 $ 146 $ 65 Expense (b) 136 136 58 Cash receipts (c) 135 122 28 Cash payments (d) 130 123 40 (a) The revenue is included in Interest expense, net, in the accompanying consolidated statement of operations and includes approximately $19 million for the years ended December 31, 2024, 2023 and 2022, respectively, of accretion income for the amortization of the purchase accounting adjustment on the Financial assets of variable interest entities. (b) The expense is included in Interest expense, net, in the accompanying consolidated statement of operations and includes approximately $7 million for the years ended December 31, 2024, 2023 and 2022 respectively, of accretion expense for the amortization of the purchase accounting adjustment on the Long-term nonrecourse financial liabilities of variable interest entities. (c) The cash receipts are interest received on the Financial assets of special purpose entities. (d) The cash payments are interest paid on Nonrecourse financial liabilities of special purpose entities. In connection with the 2006 sale of approximately 5.6 million acres of forestlands, International Paper received installment notes (the "Timber Notes") totaling approximately $4.8 billion. The Timber Notes were used as collateral for borrowings from third party lenders, which effectively monetized the Timber Notes through the creation of newly formed special purposes entities (the "Entities"). The monetization structure preserved the tax deferral that resulted from the 2006 forestlands sales. During 2015, International Paper initiated a series of actions to extend the 2006 monetization structure and maintain the long-term nature of the deferred tax liability. The Entities, with assets and liabilities primarily consisting of the Timber Notes and third-party bank loans (the "Extension Loans"), were restructured which resulted in the formation of wholly-owned, bankruptcy-remote special purpose entities (the "2015 Financing Entities"). In August 2021, the Timber Notes of $4.8 billion and the Extension Loans of $4.2 billion related to the 2015 Financing Entities both matured. We settled the Extension Loans at their maturity with the proceeds from the Timber Notes. This resulted in cash proceeds of approximately $630 million representing our equity in the variable interest entities. Maturity of the installment notes and termination of the monetization structure also resulted in a $72 million tax liability that was paid in the fourth quarter of 2021.

Debt And Lines Of Credit [Note Text Block]	Amounts related to early debt extinguishment during the years ended December 31, 2024, 2023 and 2022 were as follows: In millions 2024 2023 2022 Early debt reductions (a) $ — $ — $ 503 Pre-tax early debt extinguishment costs (b) — — 93 (a) Reductions related to notes with interest rates ranging from 4.35% to 8.70% with original maturities from 2023 to 2048 for the year ended December 31, 2022. (b) Amounts are included in Restructuring and other charges in the accompanying consolidated statements of operations. The Company had debt reductions of $141 million in 2024, related primarily to $14 million of capital leases and $127 million of environmental development bonds ("EDB"). The Company also had debt issuances of $102 million of EDBs. The Company had debt issuances in 2023 of $600 million of term loan agreements and $183 million of EDBs. The Company had debt issuances in 2022 of $354 million of term loan agreements, $410 million of commercial paper and $248 million of EDBs. 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 this 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. The Company had no borrowings outstanding as of December 31, 2024 and December 31, 2023 under this program. At December 31, 2024, the Company's 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 previously included a $1.5 billion contractually committed bank facility with a maturity date of June 2026. In June 2023, the Company amended and restated its credit agreement to, among other things, (i) reduce the size of the contractually committed bank facility from $1.5 billion to $1.4 billion, (ii) extend the maturity date from June 2026 to June 2028, and (iii) replace the LIBOR-based rate with a SOFR-based rate. The liquidity facilities also include up to $500 million of uncommitted financings based on eligible receivables balances under a receivable securitization program that expires in June 2025. As of December 31, 2024 and December 31, 2023, the Company had no borrowings outstanding under the program.

(c) The fair market value was approximately $5.2 billion at December 31, 2024 and $5.5 billion at December 31, 2023. Debt fair value measurements use Level 2 inputs. At December 31, 2024, contractual obligations for future payments of debt maturities (including finance lease liabilities disclosed in Note 9 - Leases and excluding the timber monetization structures disclosed in Note 14 - Variable Interest Entities ) by calendar year were as follows over the next five years: 2025 – $193 million; 2026 – $142 million; 2027 – $346 million; 2028 – $672 million; and 2029 – $18 million. 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 December 31, 2024, we were in compliance with our debt covenants.

Retirement Benefits [Abstract]
Retirement Plans	International Paper sponsors and maintains the Retirement Plan of International Paper Company (the "Pension Plan"), a tax-qualified defined benefit pension plan that provides retirement benefits to certain employees. 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). The Company also has two unfunded nonqualified defined benefit pension plans: the Pension Restoration Plan that provides retirement benefits based on eligible compensation in excess of limits set by the Internal Revenue Service, and the Unfunded Supplemental Retirement Plan for Senior Managers ("SERP"), which is an alternative retirement plan for salaried employees who are senior vice presidents and above or who are designated by the chief executive officer as participants. These nonqualified plans are only funded to the extent of benefits paid, which totaled $23 million, $22 million and $29 million in 2024, 2023 and 2022, respectively, and which are expected to be $49 million in 2025. Effective January 1, 2019, the Company froze participation, including credited service and compensation, for salaried employees under the Pension Plan, the Pension Restoration Plan and the SERP. This change does not affect benefits accrued through December 31, 2018. For service after December 31, 2018, employees affected by the freeze receive a Company contribution to their individual Retirement Savings Account as described later in this Note 17 . Many non-U.S. employees are covered by various retirement benefit arrangements, some of which are considered to be defined benefit pension plans for accounting purposes. OBLIGATIONS AND FUNDED STATUS The following table shows the changes in the benefit obligation and plan assets for 2024 and 2023 and the plans’ funded status. 2024 2023 In millions U.S. Non- U.S. Non- Change in projected benefit obligation: Benefit obligation, January 1 $ 8,982 $ 58 $ 8,816 $ 54 Service cost 53 3 48 4 Interest cost 447 3 459 3 Actuarial loss (gain) (547) 5 225 (3) Plan amendments 16 — 26 — Curtailments — (4) — — Settlements — (2) — — Benefits paid (609) (3) (593) (3) Special termination benefits 3 — 1 — Effect of foreign currency exchange rate movements — (4) — 3 Benefit obligation, December 31 $ 8,345 $ 56 $ 8,982 $ 58 Change in plan assets: Fair value of plan assets, January 1 $ 8,836 $ 20 $ 8,845 $ 18 Actual return on plan assets (57) 1 562 1 Company contributions 23 4 22 3 Benefits paid (609) (2) (593) (3) Settlements — (2) — — Transfer Payments (4) — — — Effect of foreign currency exchange rate movements — (1) — 1 Fair value of plan assets, December 31 $ 8,189 $ 20 $ 8,836 $ 20 Funded status, December 31 $ (156) $ (36) $ (146) $ (38) Amounts recognized in the consolidated balance sheet: Overfunded pension plan assets $ 92 $ — $ 118 $ — Underfunded pension benefit obligation - current (49) (2) (20) (2) Underfunded pension benefit obligation - non-current (199) (34) (244) (36) $ (156) $ (36) $ (146) $ (38) Amounts recognized in accumulated other comprehensive income (loss) under ASC 715 (pre-tax): Prior service cost (credit) $ 94 $ — $ 91 $ — Net actuarial loss (gain) 1,691 (5) 1,663 (10) $ 1,785 $ (5) $ 1,754 $ (10) The non-current asset for the qualified plan is included in the accompanying consolidated balance sheet under Overfunded Pension Plan Assets. The non-current portion of the liability is included with the pension liability under Underfunded Pension Benefit Obligation. The largest contributor to the actuarial loss affecting the benefit obligation was the increase in the discount rate from 5.10% at December 31, 2023 to 5.68% at December 31, 2024. The components of the $31 million and $5 million related to U.S. plans and non-U.S. plans, respectively, in the amounts recognized in other comprehensive income ("OCI") during 2024 consisted of: In millions U.S. Non- Current year actuarial (gain) loss $ 106 $ — Amortization of actuarial loss (78) — Current year prior service cost 16 — Amortization of prior service cost (13) — Settlements/curtailments — 4 Effect of foreign currency exchange rate movements — 1 $ 31 $ 5 The portion of the change in the funded status that was recognized in net periodic benefit cost and OCI for the U.S. plans was $32 million, $197 million and $474 million in 2024, 2023 and 2022, respectively. The portion of the change in funded status for the non-U.S. plans was $11 million, $2 million, and $(6) million in 2024, 2023 and 2022, respectively. The accumulated benefit obligation at December 31, 2024 and 2023 was $8.3 billion and $9.0 billion, respectively, for our U.S. defined benefit plans and $46 million and $49 million, respectively, at December 31, 2024 and 2023 for our non-U.S. defined benefit plans. The following table summarizes information for pension plans with an accumulated benefit obligation in excess of plan assets at December 31, 2024 and 2023: 2024 2023 In millions U.S. Non-U.S. U.S. Non-U.S. Projected benefit obligation $ 248 $ 55 $ 264 $ 57 Accumulated benefit obligation 248 46 264 49 Fair value of plan assets — 20 — 20 ASC 715, “Compensation – Retirement Benefits” provides for delayed recognition of actuarial gains and losses, including amounts arising from changes in the estimated projected plan benefit obligation due to changes in the assumed discount rate, differences between the actual and expected return on plan assets and other assumption changes. These net gains and losses are recognized prospectively over a period that approximates the average remaining service period of active employees expected to receive benefits under the plans to the extent that they are not offset by gains in subsequent years. NET PERIODIC PENSION EXPENSE Service cost is the actuarial present value of benefits attributed by the plans’ benefit formula to services rendered by employees during the year. Interest cost represents the increase in the projected benefit obligation, which is a discounted amount, due to the passage of time. The expected return on plan assets reflects the computed amount of current-year earnings from the investment of plan assets using an estimated long-term rate of return. Net periodic pension expense for qualified and nonqualified U.S. and non-U.S. defined benefit plans comprised the following: 2024 2023 2022 In millions U.S. Non- U.S. Non- U.S. Non- Service cost $ 53 $ 3 $ 48 $ 4 $ 85 $ 3 Interest cost 447 3 459 3 338 2 Expected return on plan assets (593) — (530) (1) (649) (1) Actuarial loss (gain) 78 — 93 (1) 87 1 Amortization of prior service cost 13 — 23 — 23 — Special termination benefits 3 — 1 — — — Net periodic pension (income) expense $ 1 $ 6 $ 94 $ 5 $ (116) $ 5 The components of net periodic pension expense other than the Service cost component are included in Non-operating pension (income) expense in the Consolidated Statement of Operations. The decrease in 2024 pension expense primarily reflects higher asset returns, lower interest cost due to a lower discount rate, and lower actuarial loss. ASSUMPTIONS International Paper evaluates its actuarial assumptions annually as of December 31 (the measurement date) and considers changes in these long-term factors based upon market conditions and the requirements for employers’ accounting for pensions. These assumptions are used to calculate benefit obligations as of December 31 of the current year and pension expense to be recorded in the following year (i.e., the discount rate used to determine the benefit obligation as of December 31, 2024 is also the discount rate used to determine net pension expense for the 2025 year). Major actuarial assumptions used in determining the benefit obligations and net periodic pension cost for our defined benefit plans are presented in the following table: 2024 2023 2022 U.S. Non- U.S. Non- U.S. Non- Actuarial assumptions used to determine benefit obligations as of December 31: Discount rate 5.68 % 4.99 % 5.10 % 5.88 % 5.40 % 5.31 % Rate of compensation increase 3.00 % 3.37 % 3.00 % 3.40 % 3.00 % 3.36 % Actuarial assumptions used to determine net periodic pension cost for years ended December 31: Discount rate (a) 5.10 % 5.88 % 5.40 % 5.31 % 2.90 % 2.59 % Expected long-term rate of return on plan assets (a) 7.00 % 3.79 % 6.50 % 3.83 % 6.00 % 3.66 % Rate of compensation increase 3.00 % 3.40 % 3.00 % 3.36 % 3.00 % 2.92 % (a) Represents the weighted average rate for the U.S. qualified plans in 2021 due to the spin-off remeasurement. The expected long-term rate of return on plan assets is based on projected rates of return for current asset classes in the plan’s investment portfolio. Projected rates of return are developed through an asset/liability study in which projected returns for each of the plan’s asset classes are determined after analyzing historical experience and future expectations of returns and volatility of the various asset classes. Based on the target asset allocation for each asset class, the overall expected rate of return for the portfolio is developed considering the effects of active portfolio management and expenses paid from plan assets. The discount rate assumption was determined from a universe of high-quality corporate bonds. A settlement portfolio is selected and matched to the present value of the plan’s projected benefit payments. To calculate pension expense for 2025, the Company will use an expected long-term rate of return on plan assets of 7.00% for the Retirement Plan of International Paper, a discount rate of 5.68% and an assumed rate of compensation increase of 3.00%. The Company estimates that it will record net pension expense of approximately $36 million for its U.S. defined benefit plans in 2025, compared to expense of $1 million in 2024. For non-U.S. pension plans, assumptions reflect economic assumptions applicable to each country. The following illustrates the effect on pension expense for 2025 of a 25 basis point decrease in the above assumptions: In millions 2025 Expense (Income): Discount rate $ 14 Expected long-term rate of return on plan assets 20 PLAN ASSETS International Paper’s Board of Directors has appointed a Fiduciary Review Committee that is responsible for fiduciary oversight of the U.S. Pension Plan, approving investment policy and reviewing the management and control of plan assets. Pension Plan assets are invested to maximize returns within prudent levels of risk. The Pension Plan maintains a strategic asset allocation policy that designates target allocations by asset class. Investments are diversified across classes and within each class to minimize the risk of large losses. Derivatives, including swaps, forward and futures contracts, may be used as asset class substitutes or for hedging or other risk management purposes. Periodic reviews are made of investment policy objectives and investment manager performance. For non-U.S. plans, assets consist principally of common stock and fixed income securities. International Paper’s U.S. pension allocations by type of fund at December 31, 2024 and 2023 and target allocations were as follows: Asset Class 2024 2023 Target Hedging assets 62 % 66 % 61% - 72% Return seeking assets (a) 38 % 34 % 28% - 39% Total 100 % 100 % (a) Return seeking assets include Real Estate (8% for 2024 and 9% for 2023) and Private Equity (7% and 7% for 2024 and 2023, respectively). The fair values of International Paper’s pension plan assets at December 31, 2024 and 2023 by asset class are shown below. Hedge funds disclosed in the following table are allocated to hedging assets for target allocation purposes.

Limited partners do not have the option to redeem partnership interests. Equity securities consist primarily of publicly traded U.S. companies and international companies. Publicly traded equities are valued at the closing prices reported in the active market in which the individual securities are traded. Fixed income consists of government securities, mortgage-backed securities, corporate bonds, common collective funds and other fixed income investments. Government securities are valued by third-party pricing sources. Mortgage-backed security holdings consist primarily of agency-rated holdings. The fair value estimates for mortgage securities are calculated by third-party pricing sources chosen by the custodian’s price matrix. Corporate bonds are valued using either the yields currently available on comparable securities of issuers with similar credit ratings or using a discounted cash flows approach that utilizes observable inputs, such as current yields of similar instruments, but includes adjustments for certain risks that may not be observable, such as credit and liquidity risks. Common collective funds are valued at the net asset value per share multiplied by the number of shares held as of the measurement date. Derivative investments such as futures, forward contracts, options and swaps are used to help manage risks. Derivatives are generally employed as asset class substitutes (such as when employed in a portable alpha strategy), for managing asset/liability mismatches, or bona fide hedging or other appropriate risk management purposes. Derivative instruments are generally valued by the investment managers or in certain instances by third-party pricing sources. The following tables summarize derivative holdings as of December 31, 2024 and 2023, respectively: Derivatives at December 31, 2024 In millions Gross Asset Gross Liability Total Collateral $ 17 $ (1) $ 16 Credit Default Swap 3 — 3 Interest Rate Swap 7 — 7 Bond/Equity Swap — (17) (17) Total $ 27 $ (18) $ 9 Derivatives at December 31, 2023 In millions Gross Asset Gross Liability Total Collateral $ 7 $ (7) $ — Credit Default Swap 2 — 2 Interest Rate Swap 4 — 4 Bond/Equity Swap 65 — 65 Total $ 78 $ (7) $ 71 Hedge funds are investment structures for managing private, loosely-regulated investment pools that can pursue a diverse array of investment strategies with a wide range of different securities and derivative instruments. These investments are made through funds-of-funds (commingled, multi-manager fund structures) and through direct investments in individual hedge funds. Hedge funds are primarily valued by each fund’s third-party administrator based upon the valuation of the underlying securities and instruments and primarily by applying a market or income valuation methodology as appropriate depending on the specific type of security or instrument held. Funds-of-funds are valued based upon the net asset values of the underlying investments in hedge funds. Private equity consists of interests in partnerships that invest in U.S. and non-U.S. debt and equity securities. Partnership interests are valued using the most recent general partner statement of fair value, updated for any subsequent partnership interest cash flows. Real estate funds include commercial properties, land and timberland, and generally include, but are not limited to, retail, office, industrial, multifamily and hotel properties. Real estate fund values are primarily reported by the fund manager and are based on valuation of the underlying investments which include inputs such as cost, discounted cash flows, independent appraisals and market based comparable data. The following is a reconciliation of the assets that are classified using significant unobservable inputs (Level 3) at December 31, 2024: Fair Value Measurements Using Significant Unobservable Inputs (Level 3) In millions Other Derivatives Total Beginning balance at December 31, 2022 $ 7 $ 25 $ 32 Actual return on plan assets: Relating to assets still held at the reporting date — 57 57 Relating to assets sold during the period — 48 48 Purchases, sales and settlements — (59) (59) Transfers in and/or out of Level 3 — — — Ending balance at December 31, 2023 $ 7 $ 71 $ 78 Actual return on plan assets: Relating to assets still held at the reporting date — (80) (80) Relating to assets sold during the period — 31 31 Purchases, sales and settlements — (13) (13) Transfers in and/or out of Level 3 — — — Ending balance at December 31, 2024 $ 7 $ 9 $ 16 FUNDING AND CASH FLOWS The Company’s funding policy for the Pension Plan is to contribute amounts sufficient to meet legal funding requirements, plus any additional amounts that the Company may determine to be appropriate considering the funded status of the plans, tax deductibility, cash flow generated by the Company, and other factors. The Company continually reassesses the amount and timing of any discretionary contributions. No voluntary contributions were made in 2022, 2023 or 2024. Generally, International Paper’s non-U.S. pension plans are funded using the projected benefit as a target, except in certain countries where funding of benefit plans is not required. At December 31, 2024, projected future pension benefit payments, excluding any termination benefits, were as follows: In millions 2025 $ 663 2026 638 2027 639 2028 638 2029 637 2030-2034 3,135 OTHER U.S. PLANS International Paper sponsors the International Paper Company Salaried Savings Plan and the International Paper Company Hourly Savings Plan, both of which are tax-qualified defined contribution 401(k) savings plans. Substantially all U.S. salaried and certain hourly employees are eligible to participate and may make elective deferrals to such plans to save for retirement. International Paper makes matching contributions to participant accounts on a specified percentage of employee deferrals as determined by the provisions of each plan. The Company makes Retirement Savings Account contributions equal to a percentage of an eligible employee’s pay. Beginning in 2019, as a result of the freeze for salaried employees under the Pension Plan, all salaried employees are eligible for the contribution to the Retirement Savings Account.

Defined Benefit Plan	U.S. POSTRETIREMENT BENEFITS International Paper provides certain retiree health care and life insurance benefits covering certain U.S. salaried and hourly employees. These employees are generally eligible for benefits upon retirement and completion of a specified number of years of creditable service. International Paper does not fund these benefits prior to payment and has the right to modify or terminate certain of these plans in the future. In addition to the U.S. plan, certain Moroccan employees are eligible for retiree health care and life insurance benefits. The components of postretirement benefit expense in 2024, 2023 and 2022 were as follows: In millions 2024 2023 2022 U.S. Non- U.S. Non- U.S. Non- Interest cost $ 6 $ — $ 7 $ — $ 5 $ — Actuarial loss 1 — — — 3 — Net postretirement expense $ 7 $ — $ 7 $ — $ 8 $ — International Paper evaluates its actuarial assumptions annually as of December 31 (the measurement date) and considers changes in these long-term factors based upon market conditions and the requirements of employers’ accounting for postretirement benefits other than pensions. The discount rate assumption was determined based on a hypothetical settlement portfolio selected from a universe of high-quality corporate bonds. The discount rates used to determine net U.S. and non-U.S. postretirement benefit cost for the years ended December 31, 2024, 2023 and 2022 were as follows: 2024 2023 2022 U.S. Non- U.S. Non- U.S. Non- Discount rate 5.20 % 6.10 % 5.50 % 5.70 % 2.90 % 5.20 % The weighted average assumptions used to determine the benefit obligation at December 31, 2024 and 2023 were as follows: 2024 2023 U.S. Non- U.S. Non- Discount rate 5.67 % 5.70 % 5.20 % 6.10 % Health care cost trend rate assumed for next year 6.75 % 4.00 % 7.00 % 4.00 % Rate that the cost trend rate gradually declines to 5.00 % 4.00 % 5.00 % 4.00 % Year that the rate reaches the rate it is assumed to remain 2032 2024 2032 2023 The plans are only funded in an amount equal to benefits paid.

Share-Based Payment Arrangement, Additional Disclosure [Abstract]
Share-based Payment Arrangement	On February 13, 2024, the Company's Board of Directors, upon recommendation of the Management Development and Compensation Committee (the "MDCC"), authorized adoption of a 2024 Long-Term Incentive Compensation Plan (the "2024 LTICP") to replace the 2009 Amended and Restated Incentive Compensation Plan (the "2009 Plan"), subject to shareholder approval at the Company's annual meeting of shareholders held on May 13, 2024. The 2024 LTICP became effective following approval by shareholders at the May 13, 2024 annual meeting and replaced the 2009 Plan. The 2024 LTICP authorized up to 9,250,000 shares of our Class A common stock, par value $1.00 per share, available for future grants in the form 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 Committee. The LTICP is administered by the Committee. Additionally, restricted stock, which may be deferred into RSUs, may be awarded under a Restricted Stock and Deferred Compensation Plan for Non-Employee Directors. LONG-TERM INCENTIVE PLAN Effective January 1, 2023, the MDCC renamed the Performance Share Plan ("PSP") to the Long-Term Incentive Plan ("LTIP") and began incorporating RSUs into its annual grant process as a complement to PSUs to better align with market and aid in our recruitment and retention efforts. Under the LTIP, contingent awards of International Paper common stock are granted by the MDCC. The maximum aggregate number of shares of the Company’s common stock that may be issued pursuant to awards under the LTICP shall not exceed 9,250,000 shares. Shares for which payment is in cash, including the shares withheld to cover associate payroll taxes, as well as shares that expire, terminate, or are canceled or forfeited, may be awarded or granted again under the LTICP. Performance Stock Units PSU awards are earned over a three-year period based on the achievement of pre-established performance goals of Return on Invested Capital ("ROIC") measured against our internal benchmark and our relative performance in Total Shareholder Return ("TSR") compared to the TSR peer group. The 2022-2024, 2023-2025 and 2024-2026 Awards are weighted 50% ROIC and 50% TSR for all participants. The ROIC component of the PSU awards is valued at the 20-trading day average closing price immediately prior to the grant date. As the ROIC component contains a performance condition, compensation expense, net of estimated forfeitures, is recorded over the requisite service period based on the most probable number of awards expected to vest. The TSR component of the PSU awards is valued using the same methodology as the RSUs but then adjusted using a factor derived from a Monte Carlo simulation as the TSR component contains a market condition. The Monte Carlo simulation estimates the fair value of the TSR component based on the expected term of the award, a risk-free rate, expected dividends, and the expected volatility for the Company and its competitors. The expected term is estimated based on the vesting period of the awards, the risk-free rate is based on the yield on U.S. Treasury securities matching the vesting period, and the volatility is based on the Company’s historical volatility over the expected term. PSUs are payable in cash or shares at the Company's discretion. Restricted Stock Units Time-based RSU awards granted under the LTIP are expected to vest in three equal installments commencing on February 1st following the first anniversary of the grant date over a 3-year service period, subject to forfeiture and transfer restrictions. RSUs are payable in cash or shares at the Company’s discretion. Generally, the requisite service period is the vesting period. In the case of retirement (eligibility for which is based on the associate's age and years of service as provided in the relevant award agreement), awards vest pro-rata based on length of service during the award period, subject to continued employment and paid upon termination. Dividend equivalents are generally accrued on PSUs and RSUs outstanding as of the record date. These dividend equivalents are paid only on PSUs and RSUs that ultimately vest. The following table sets forth the assumptions used to determine compensation cost for the market condition component of the LTIP plan: Twelve Months Ended December 31, 2024 Expected volatility 27.09% - 37.11% Risk-free interest rate 0.97% - 4.79% The following summarizes LTIP activity for the three years ended December 31, 2024: Share/Units Weighted Outstanding at December 31, 2021 5,926,142 $35.43 Granted 1,899,211 50.32 Shares issued (1,130,236) 40.23 Forfeited (1,382,637) 42.03 Outstanding at December 31, 2022 5,312,480 38.01 Granted - LTIP PSU 1,619,481 37.78 Granted - LTIP RSU 1,411,042 34.63 Shares issued - LTIP PSU (972,563) 40.44 Shares issued - LTIP RSU (15,161) 34.63 Forfeited (1,234,328) 45.38 Outstanding at December 31, 2023 6,120,951 35.31 Granted - LTIP PSU 2,039,725 35.28 Granted - LTIP RSU 1,414,316 36.15 Shares issued - LTIP PSU (851,962) 53.32 Shares issued - LTIP RSU (446,582) 34.63 Shares issued - LTIP RSU (8,060) 36.15 Forfeited (1,350,063) 45.58 Outstanding at December 31, 2024 6,918,325 $31.29 RECOGNITION AWARD PROGRAM The Recognition Award Program ("RA Program") is service-based and designed for recruitment, retention and special recognition purposes.

Segment Reporting, Measurement Disclosures [Abstract]
Financial Information By Business Segment And Geographic Area	International Paper operates in two segments: Industrial Packaging and Global Cellulose Fibers. Industrial Packaging is primarily focused on producing fiber-based packaging. We produce linerboard, medium, whitetop, recycled linerboard, recycled medium and saturating kraft of which approximately 75% of our production is converted into corrugated packaging and other packaging. The revenue for our Industrial Packaging segment is derived from selling these products to our customers. Global Cellulose Fibers primarily focus 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 accounting policies of the Industrial Packaging and Global Cellulose Fibers segments are the same as those described in the summary of significant accounting policies. The chief operating decision maker ("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. During 2024, business segment operating profits (losses) used by the CODM were adjusted to include accelerated depreciation as part of the measure of business performance. As such, results for the year ended December 31, 2023 have been recast to reflect $422 million for accelerated depreciation related to mill strategic actions in business segment operating profit (losses). International Paper's reportable segments are strategic business units that offer different products. They are managed separately because each business requires different resources and strategies. International Paper’s CODM is the chief executive officer. External sales by major product is determined by aggregating sales from each segment based on similar products or services. External sales are defined as those that are made to parties outside International Paper’s consolidated group, whereas sales by segment in the Net Sales table are determined using a management approach and include intersegment sales. INFORMATION BY BUSINESS SEGMENT The following tables illustrate reportable segment revenue, significant segment expenses, and measures of a segment’s profit or loss for the years ended December 31, 2024, 2023 and 2022. The table also reconciles these amounts to Earnings (loss) from continuing operations before income taxes and equity earnings. 2024: In millions Industrial Packaging Global Cellulose Fibers Total Net Sales $ 15,534 $ 2,793 $ 18,327 Corporate and Intrasegment Sales 292 Total Net Sales 18,619 Less: Cost of products sold 10,985 1,983 Selling and administrative expenses 1,451 262 Depreciation and amortization 850 450 Distribution expenses 1,179 295 Other segment items (a) 118 29 Business Segment Operating Profit (Losses) 951 (226) 725 Interest Expense, net 208 Adjustment for less than wholly owned subsidiaries (b) (5) Corporate expenses, net 44 Corporate net special items 251 Business net special items 122 Non-operating pension (income) expense (42) Earnings (losses) from continuing operations before income taxes and equity earnings (losses) $ 147 2023: In millions Industrial Packaging Global Cellulose Fibers Total Net Sales $ 15,596 $ 2,890 $ 18,486 Corporate and Intrasegment Sales 430 Total Net Sales 18,916 Less: Cost of products sold 11,093 2,121 Selling and administrative expenses 1,078 211 Depreciation and amortization 1,144 286 Distribution expenses 1,240 335 Other segment items (a) 122 29 Business Segment Operating Profit (Losses) 919 (92) 827 Interest Expense, net 231 Adjustment for less than wholly owned subsidiaries (b) (2) Corporate expenses, net 27 Corporate net special items 28 Business net special items 107 Non-operating pension (income) expense 54 Earnings (losses) from continuing operations before income taxes and equity earnings (losses) $ 382 2022 : In millions Industrial Packaging Global Cellulose Fibers Total Net Sales $ 17,451 $ 3,227 $ 20,678 Corporate and Intrasegment Sales 483 Total Net Sales 21,161 Less: Cost of products sold 12,509 2,183 Selling and administrative expenses 983 189 Depreciation and amortization 783 255 Distribution expenses 1,315 468 Other segment items (a) 119 26 Business Segment Operating Profit (Losses) 1,742 106 1,848 Interest Expense, net 325 Adjustment for less than wholly owned subsidiaries (b) (5) Corporate expenses, net 34 Corporate net special items 99 Business net special items 76 Non-operating pension (income) expense (192) Earnings (losses) from continuing operations before income taxes and equity earnings (losses) $ 1,511 Assets In millions 2024 2023 Industrial Packaging $ 15,805 $ 16,060 Global Cellulose Fibers 2,857 3,369 Corporate and other 4,138 3,832 Assets $ 22,800 $ 23,261 Capital Spending In millions 2024 2023 2022 Industrial Packaging $ 763 $ 928 $ 762 Global Cellulose Fibers 133 177 143 Subtotal 896 1,105 905 Corporate and other 25 36 26 Capital Spending $ 921 $ 1,141 $ 931 External Sales By Major Product In millions 2024 2023 2022 Industrial Packaging $ 15,533 $ 15,596 $ 17,441 Global Cellulose Fibers 2,784 2,883 3,219 Other 302 437 501 Net Sales $ 18,619 $ 18,916 $ 21,161 INFORMATION BY GEOGRAPHIC AREA Net Sales (c) In millions 2024 2023 2022 United States (d) $ 16,300 $ 16,340 $ 18,482 EMEA 1,432 1,494 1,693 Pacific Rim and Asia 157 261 123 Americas, other than U.S. 730 821 863 Net Sales $ 18,619 $ 18,916 $ 21,161 Long-Lived Assets (e) In millions 2024 2023 United States $ 8,617 $ 9,021 EMEA 706 757 Americas, other than U.S. 352 390 Long-Lived Assets $ 9,675 $ 10,168 (a) Other segment items includes Taxes other than payroll.

Our CISO stays current on cybersecurity issues and trends through continuing education activities such as participation at conferences and in webinars. Our CISO reports to our Chief Financial Officer. Additionally, our CISO and members of the cybersecurity team hold a number of industry recognized certifications, such as Certified Information Systems Security Professional, Certified Information Security Manager, and Certified Ethical Hacker, among others. The Company has also adopted a cyber-incident response plan which provides for controls and procedures in connection with cybersecurity events, including escalation procedures summarized below. The cyber-incident response plan is designed to address non-operational and operational cybersecurity events. Evaluation and response to cybersecurity events is led by our Cybersecurity Incident Response Team (“CIRT”), under the direction of our CISO. The CIRT is comprised of subject matter experts representing information security, information technology, operational technology and legal. The CIRT performs an impact assessment with respect to cybersecurity incidents, gathers facts and provides a chronology of events in connection therewith, and leads remediation and recovery activities. Our General Counsel, Senior Vice President, Chief People and Strategy Officer, Chief Ethics and Compliance Officer (or their respective designees), and CISO review and assess significant non-operational data breaches. Cybersecurity events that meet specified criteria for operational impact are escalated for further review to our Business Continuity Incident Command Team (“Incident Command Team”). The Incident Command Team performs an initial assessment that includes evaluation of the cybersecurity event’s severity, response required, and estimated business cost, and leads the execution of business continuity plans to maintain Company operations. Cybersecurity events meeting certain criteria are escalated to our Disclosure Committee, General Counsel and Chief Financial Officer for further review, and, if appropriate, may be further elevated for the review of the Board of Directors. The Disclosure Committee, General Counsel and Chief Financial Officer assess and determine materiality using the facts gathered and chronology of events provided by the Incident Command Team.

Accounting Policies [Abstract]
Nature Of Business	NATURE OF BUSINESS International Paper (the "Company") is a global producer of renewable fiber-based packaging and pulp products with primary markets and manufacturing operations in North America and Europe and additional markets and manufacturing operations in Latin America, North Africa and Asia. Substantially all of our businesses have experienced, and are likely to continue to experience, cycles relating to available industry capacity and general economic conditions.
Basis of Accounting, Policy	FINANCIAL STATEMENTS These consolidated financial statements have been prepared in conformity with accounting principles generally accepted in the United States that require the use of management’s estimates. Actual results could differ from management’s estimates. Certain amounts from prior year have been reclassified to conform with the current year financial statement presentation.
Discontinued Operations	ISCONTINUED OPERATIONS A discontinued operation may include a component or a group of components of the Company's operations. A disposal of a component or a group of components is reported in discontinued operations if the disposal represents a strategic shift that has or will have a major effect on the Company's operations and financial results when the following occurs: (1) a component (or group of components) meets the criteria to be classified as held for sale; (2) the component or group of components is disposed of by sale; or (3) the component or group of components is disposed of other than by sale (for example, by abandonment or in a distribution to owners in a spin-off). For any component classified as held for sale or disposed of by sale or other than by sale, qualifying for presentation as a discontinued operation, the Company reports the results of operations of the discontinued operations (including any gain or loss recognized on the disposal or loss recognized on classification as held for sale of a discontinued operation), less applicable income taxes (benefit), as a separate component in the consolidated statement of operations for current and all prior periods presented. The Company also reports assets and liabilities associated with discontinued operations as separate line items on the consolidated balance sheet. The Company recorded discontinued operations for the years ended December 31, 2023 and 2022 in connection with the sale of its equity method investment in Ilim. See Note 10 for further details.
Consolidation	CONSOLIDATION The consolidated financial statements include the accounts of International Paper and subsidiaries for which we have a controlling financial interest, including variable interest entities for which we are the primary beneficiary. All significant intercompany balances and transactions are eliminated.
Equity Method Investments	EQUITY METHOD INVESTMENTS The equity method of accounting is applied for investments when the Company has significant influence over the investee’s operations, or when the investee is structured with separate capital accounts. Our material equity method investments are described in Note 10
Asset Impairment Charges	OTHER-THAN-TEMPORARY IMPAIRMENT T he Company evaluates our equity method investments for other-than-temporary impairment ("OTTI") when circumstances indicate the investment may be impaired. When a decline in fair value is deemed to be an OTTI, an impairment is recognized to the extent that the fair value is less than the carrying value of the investment. We consider various factors in determining whether a loss in value of an investment is other than temporary including: the length of time and the extent to which the fair value has been below cost, the financial condition of the investee, and our intent and ability to retain the investment for a period of time sufficient to allow for recovery of value. Management makes certain judgments and estimates in its assessment including but not limited to: identifying if circumstances indicate a decline in value is other than temporary, expectations about operations, as well as industry, financial, regulatory and market factors.
Business Combinations	BUSINESS COMBINATIONS The Company allocates the total consideration 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 cash flows, anticipated growth rates, discount rates, 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 statement of operations. Subsequent actual results of the underlying business activity supporting the specifically identified intangible assets could change, requiring us to record impairment charges or adjust their economic lives in future periods. See Note 7 for further details.
Restructuring Liabilities and Costs	RESTRUCTURING LIABILITIES AND COSTS For operations to be closed or restructured, a liability and related expense is recorded in the period when operations cease. For termination costs associated with employees covered by a written or substantive plan, a liability is recorded when it is probable that employees will be entitled to benefits and the amount can be reasonably estimated. For termination costs associated with employees not covered by a written and broadly communicated policy covering involuntary termination benefits (severance plan), a liability is recorded for costs to terminate employees (one-time termination benefits) when the termination plan has been approved and committed to by management, the employees to be terminated have been identified, the termination plan benefit terms are communicated, the employees identified in the plan have been notified and actions required to complete the plan indicate that it is unlikely that significant changes to the plan will be made or that the plan will be withdrawn. The timing and amount of an accrual is dependent upon the type of benefits granted, the timing of communication and other provisions that may be provided in the benefit plan. The accounting for each termination is evaluated individually. See Note 6 for further details.
Revenue Recognition	REVENUE RECOGNITION Generally, the Company recognizes revenue on a point-in-time basis when the Company transfers control of the goods to the customer. 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. The Company’s revenue is primarily derived from fixed consideration; however, we do have contract terms that give rise to variable consideration, primarily volume rebates, early payment discounts and other customer refunds. The Company estimates its volume rebates at the individual customer level based on the most likely amount method outlined in ASC 606 "Revenue from Contracts with Customers". The Company estimates early payment discounts and other customer refunds based on the historical experience across the Company's portfolio of customers to record reductions in revenue that is consistent with the expected value method outlined in ASC 606. Management has concluded that these methods result in the best estimate of the consideration the Company will be entitled to from its customers. The Company has elected to present all sales taxes on a net basis, account for shipping and handling activities as fulfillment activities, recognize the incremental costs of obtaining a contract as expense when incurred if the amortization period of the asset the Company would recognize is one year or less, and not record interest income or interest expense when the difference in timing of control or transfer and customer payment is one year or less. See Note 3 for further details.
Temporary Investments, Policy	TEMPORARY INVESTMENTS Temporary investments with an original maturity of three months or less and money market funds with greater than three-month maturities but with the right to redeem without notice are treated as cash equivalents and are stated at cost, which approximates market value. See Note 8 for further details.
Inventories	INVENTORIES Inventories include all costs directly associated with manufacturing products: materials, labor, and manufacturing overhead. In the United States, costs of raw materials and finished pulp and paper products are generally determined using the last-in, first-out method. These inventories are measured at the lower of cost or market. Other inventories are valued using the first-in, first-out or average cost methods. These inventories are measured at the lower of cost or net realizable value. See Note 8 for further details.
Leased Assets	LEASED ASSETS Operating lease right of use ("ROU") assets and liabilities are recognized at the commencement date of the lease based on the present value of lease payments over the lease term. The Company's leases may include options to extend or terminate the lease. These options to extend are included in the lease term when it is reasonably certain that we will exercise that option. Some leases have variable payments, however, because they are not based on an index or rate, they are not included in the ROU assets and liabilities. Variable payments for real estate leases primarily relate to common area maintenance, insurance, taxes and utilities. Variable payments for equipment, vehicles, and leases within supply agreements primarily relate to usage, repairs and maintenance. As the implicit rate is not readily determinable for most of the Company's leases, the Company applies a portfolio approach using an estimated incremental borrowing rate to determine the initial present value of lease payments over the lease terms on a collateralized basis over a similar term, which is based on market and company specific information. We use the unsecured borrowing rate and risk-adjust that rate to approximate a collateralized rate, and apply the rate based on the currency of the lease, which is updated on a quarterly basis for measurement of new lease liabilities. Leases having a lease term of twelve months or less are not recorded on the balance sheet and the related lease expense is recognized on a straight-line basis over the term of the lease. In addition, the Company has applied the practical expedient to account for the lease and non-lease components as a single lease component for all of the Company's leases except for certain gas and chemical agreements. See Note 9 for further details.
Plants, Properties And Equipment	PLANTS, PROPERTIES AND EQUIPMENT Plants, properties and equipment are stated at cost, less accumulated depreciation. Expenditures for betterments are capitalized, whereas normal repairs and maintenance are expensed as incurred. The units-of-production method of depreciation is used for pulp and paper mills, and the straight-line method is used for other plants and equipment. If a decision is made to abandon plants, properties or equipment before the end of its useful life, depreciation expense is revised to reflect the shortened useful life. See Note 8 for further details.
Goodwill	GOODWILL Annual evaluation for possible goodwill impairment is performed as of the beginning of the fourth quarter of each year, with additional interim evaluation performed when management believes that it is more likely than not, that events or circumstances have occurred that would result in the impairment of a reporting unit’s goodwill. The Company has the option to evaluate goodwill for impairment by first performing a qualitative assessment of events and circumstances to determine whether it is more likely than not that the fair value of a reporting unit is less than its carrying amount. If, after assessing the totality of events or circumstances, the Company determines that it is not more likely than not that the fair value of a reporting unit is less than its carrying amounts, then the quantitative goodwill impairment test is not required to be performed. If the Company determines that it is more likely than not that the fair value of a reporting unit is less than its carrying amount, or if the
Impairment Of Long-Lived Assets	IMPAIRMENT OF LONG-LIVED ASSETS
Income Taxes	INCOME TAXES International Paper uses the asset and liability method of accounting for income taxes whereby deferred income taxes are recorded for the future tax consequences attributable to differences between the financial statement and tax bases of assets and liabilities. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. Deferred tax assets and liabilities are remeasured to reflect new tax rates in the periods rate changes are enacted. International Paper records its global tax provision based on the respective tax rules and regulations for the jurisdictions in which it operates. Where the Company believes that a tax position is supportable for income tax purposes, the item is included in its income tax returns. Where treatment of a position is uncertain, liabilities are recorded based upon the Company’s evaluation of the “more likely than not” outcome considering technical merits of the position based on specific tax regulations and facts of each matter. Changes to recorded liabilities are only made when an identifiable event occurs that changes the likely outcome, such as settlement with the relevant tax authority, the expiration of statutes of limitation for the subject tax year, change in tax laws, or recent court cases that are relevant to the matter. Accrued interest related to these uncertain tax positions is recorded in our consolidated statement of operations in Interest expense, net. The judgments and estimates made by the Company are based on management’s evaluation of the technical merits of a matter, assisted as necessary by consultation with outside consultants, historical experience and other assumptions that management believes are appropriate and reasonable under current circumstances. Actual resolution of these matters may differ from recorded estimated amounts, resulting in adjustments that could materially affect future financial statements. See Note 12 for further details. Valuation allowances are recorded to reduce deferred tax assets when it is more likely than not that a tax benefit will not be realized. Significant judgment is required in assessing the need for and magnitude of appropriate valuation allowances against deferred tax assets. This assessment is completed by tax jurisdiction and relies on both positive and negative evidence available, with significant weight placed on recent financial results. Cumulative reported pre-tax income is considered objectively verifiable positive evidence of our ability to generate positive pre-tax income in the future. In accordance with GAAP, when there is a recent history of pre-tax losses, there is little or no weight placed on forecasts for purposes of assessing the recoverability of our deferred tax assets. When necessary, we use systematic and logical methods to estimate when deferred tax liabilities will reverse and generate taxable income and when deferred tax assets will reverse and generate tax deductions. Assumptions, judgment, and the use of estimates are required when scheduling the reversal of deferred tax assets and liabilities, and the exercise is inherently complex and subjective. The realization of these assets is dependent on generating future taxable income, as well as successful implementation of various tax planning strategies. International Paper uses the flow-through method to account for investment tax credits earned on eligible open-loop biomass facilities and combined heat and power system expenditures. Under this method, the investment tax credits are recognized as a reduction to income tax expense in the year they are earned rather than a reduction in the asset basis.
Environmental Remediation Costs	ENVIRONMENTAL REMEDIATION COSTS Costs associated with environmental remediation obligations are accrued when such costs are probable and reasonably estimable. Such accruals are adjusted as further information develops or circumstances change. See Note 13 for further details.
Translation Of Financial Statements	TRANSLATION OF FINANCIAL STATEMENTS Balance sheets of international operations are translated into U.S. dollars at year-end exchange rates, while statements of operations are translated at average rates. Adjustments resulting from financial statement translations are included as cumulative translation adjustments in Accumulated other comprehensive income (loss).
Fair Value Measurement, Policy	FAIR VALUE MEASUREMENTS The guidance for fair value measurements and disclosures sets out a fair value hierarchy that groups fair value measurement inputs into the following three classifications: Level 1: Quoted market prices in active markets for identical assets or liabilities. Level 2: Observable market-based inputs other than quoted prices included within Level 1 that are observable for the asset or liability, either directly or indirectly. Level 3: Unobservable inputs for the asset or liability reflecting the reporting entity’s own assumptions or external inputs from inactive markets. Transfers between levels are recognized at the end of the reporting period.
