INTERNATIONAL PAPER CO NEW

Full-year 2024 net earnings attributable to shareholders were $557 million ($1.57 per diluted share) compared with $288 million ($0.82 per diluted share) for full-year 2023.

In 2024, we initiated our strategy to deliver profitable growth as the low-cost, most reliable and innovative sustainable packaging solutions provider for our customers. Through a disciplined 80/20 approach, we restructured our corporate organization, added resources to the business, reduced structural costs through footprint actions and successfully piloted regional box plant optimization. Our earnings stabilized in the fourth quarter 2024 and we intend to accelerate earnings improvement in 2025. Our Go-to-Market value over volume reset was largely complete in 2024 and we expect the final unfavorable impacts to volume to be behind us later in 2025. There was a significant focus throughout 2024 on cost reduction. This included a zero-up approach to the corporate organization, including shifting resources to the business and reducing corporate staffing to the level required as a public company. We expect this to reduce costs by approximately $120 million on a run rate basis. Additionally, we made the challenging decision to close five box plants and our Global Cellulose Fibers Georgetown, South Carolina mill. These actions are expected to remove roughly another $110 million of annual cost on a run rate basis. Mill reliability was an issue in 2024 resulting in elevated costs throughout the year. This presents a significant cost reduction opportunity and we will continue to improve the reliability at our mills and optimize our mill and box system so that we are able to reduce structural costs. Finally, we completed the acquisition of DS Smith on January 31, 2025, creating a global leader in sustainable packaging solutions, focused on the attractive and growing North American and EMEA regions.

Comparing 2024 financial performance to 2023, sales in our North American Industrial Packaging business were relatively flat versus the prior year. This was due in part to higher price and mix driven by favorable prior index movements and the execution of our go-to-market strategy. The improved price and mix was offset by lower volumes as we worked through

customer contract restructuring. This decline was in line with our expectations. Sales in our Global Cellulose Fibers business were lower compared to prior year. This was due to lower price and mix driven by prior index movements. Volume was relatively flat versus 2023. Cost of products sold in our North American Industrial Packaging business was lower versus the prior year in line with lower sales during 2024 along with lower maintenance outage expenses. This was partially offset by higher costs associated with mill reliability issues along with increased input costs on higher recovered fiber costs. Cost of products sold in our Global Cellulose Fibers business was lower versus the prior year in line with lower sales during 2024 along with lower maintenance outage expenses and lower input costs. Cost of products sold includes higher costs associated with mill reliability issues. Selling and administrative expenses were higher in our North American Industrial Packaging and Global Cellulose Fibers businesses primarily driven by higher employee incentive compensation expense. Distribution expenses were lower in both our North American Industrial Packaging and Global Cellulose Fibers businesses primarily driven by lower freight expense on reduced sales.

Looking ahead to the first quarter 2025 in our North American Industrial Packaging business, as compared to the fourth quarter 2024 and without consideration of the DS Smith acquisition, we expect slightly lower price and mix based on lower export pricing observed to date along with an unfavorable seasonal mix impact. Volume is expected to be slightly higher in the first quarter 2025 due to two more shipping days partially offset by the near-term impact of our go-to-market strategy. Operations and costs are expected to increase earnings driven by the benefits of our box plant optimization as well as the non-repeat of the higher incentive compensation costs and other unfavorable items from the fourth quarter 2024. Maintenance outage expense is expected to be marginally lower relative to the fourth quarter 2024. Input costs are expected to be relatively flat as higher energy costs will be offset by lower recovered fiber costs. Finally, in February we announced our plan to close the containerboard mill in Campti, Louisiana with operations expected to cease by March 31, 2025. We estimate that the closure will result in aggregate pre-tax charges of approximately $357 million, including pre-tax noncash asset write-offs of approximately $311 million (of which $276 million is accelerated depreciation), and pre-tax cash severance and other shutdown charges of approximately $46 million. In our Global Cellulose Fibers business, we expect price and mix to be lower due to unfavorable prior index movements. We expect volume to be relatively flat. Operations and costs are expected to increase earnings due to improved mill performance and reliability along with the non-repeat of the higher incentive compensation costs and other unfavorable one-time items from the fourth quarter 2024. Maintenance outage expense is expected to decrease earnings while input costs are expected to be stable relative to the fourth quarter 2024.

In closing, we believe 2025 will be a transformational year. During the first few months, we anticipate earnings will continue the stabilization trend we saw in the fourth quarter 2024. As we progress further in the year, we expect our earnings to progressively ramp up as the commercial contract restructuring is completed and the 80/20 initiatives deliver value. We have an ambitious pipeline of capital projects that we predict will facilitate the regional optimization of our box system and deliver profitable market share growth. We believe we are well on our way to building a performance-driven and customer-centric culture. We are confident we have developed the right strategy and a concrete plan that will deliver customer excellence and drive profitable growth. We believe our actions will drive transformational improvements and create significant value for our shareholders.

Acquisition of DS Smith

On January 31, 2025, the Company, through its indirect wholly owned subsidiary, International Paper UK Holdings Limited, completed the closing (the “Closing”) of its previously announced business combination of the entire issued and to be issued ordinary shares of DS Smith plc, a public limited company registered in England and Wales that has since been re-registered as DS Smith Limited, a private limited company (“DS Smith”). The business combination was effected by means of a court-sanctioned scheme of arrangement between DS Smith and shareholders of DS Smith under Part 26 of the UK Companies Act 2006, as amended.

The consummation followed the Company’s April 16, 2024 announcement pursuant to Rule 2.7 of the United Kingdom City Code on Takeovers and Mergers disclosing the terms of the business combination (the “Rule 2.7 Announcement”), pursuant to which, for each ordinary share of DS Smith (the “DS Smith Shares”), DS Smith shareholders would receive 0.1285 of a new share of common stock of the Company, par value $1.00 per share (the “Company Common Stock”), resulting in the issuance of 178,126,631 new shares of Company Common Stock (the “New Company Common Stock”).

On January 24, 2025, the European Commission issued its Phase I clearance of the business combination, conditional on International Paper

entering into commitments to divest its plants in Mortagne, Saint-Amand, and Cabourg (France), Over (Portugal) and Bilbao (Spain). As such, the Company has agreed to divest these locations.

On February 4, 2025, the DS Smith Shares were delisted from the London Stock Exchange (the “LSE”) and the shares of New Company Common Stock began trading on the New York Stock Exchange under the symbol “IP” and the shares of Company Common Stock, including the shares of New Company Common Stock, began trading on the LSE via a secondary listing under the symbol “IPC.”

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

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

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

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

(a) Adjusted operating earnings (non-GAAP), and adjusted operating earnings per share (non-GAAP) for the year ended December 31, 2023, included in this Annual Report on Form 10-K have been adjusted to include the pre-tax charge of $422 million for accelerated depreciation related to mill strategic actions in the year ended December 31, 2023. This charge was previously treated as a special item and excluded from these non-GAAP earnings measures.

(b) Special items for the year ended December 31, 2024 include a tax benefit of $416 million related to internal legal entity restructuring. This amount also includes tax expense of $10 million on the non-operating pension income and a tax benefit of $72 million associated with special items. Special items for the year ended December 31, 2023 includes a tax benefit of $23 million for the settlement of tax audits and tax expense of $4 million related to internal legal entity restructuring. This amount also includes tax benefit of $13 million on the non-operating pension expense and a tax benefit of $36 million associated with special items.

(a) This amount for the three months ended December 31, 2024 includes tax expense of $2 million on the non-operating pension income and a tax benefit of $36 million associated with special items. Special items for the three months ended September 30, 2024 include a tax benefit of $78 million related to internal legal entity restructuring. This amount also includes tax expense of $3 million on the non-operating pension income and a tax benefit of $24 million associated with special items. Special items for the

three months ended December 31, 2023 include tax expense of $4 million related to internal legal entity restructuring. This amount also includes tax benefit of $3 million on the non-operating pension expense and a tax benefit of $30 million associated with special items.

Effects of Net Special Items Expense (Income)

Pre-tax special items included in continuing operations totaling $363 million and $150 million were recorded in 2024 and 2023, respectively. Details of these charges were as follows:

(a) Severance and other closure costs associated with our mill strategic actions recorded in restructuring and other charges, net.

(b) Severance and other costs associated with the Company's 80/20 strategic approach which includes the realignment of resources recorded in restructuring and other charges, net.

(c) Transaction related costs that the Company believes are not reflective of the Company's underlying operations recorded in selling and administrative expenses.

(d) Environmental remediation adjustments associated with remediation work at sites that have been closed/divested that the Company believes are not reflective of the Company's underlying operations recorded in cost of products sold.

(e) The Company's cost for third-party damages associated with a warehouse fire in Morocco recorded in cost of products sold.

(f) Legal reserve adjustment associated with a previously discontinued business recorded in cost of products sold.

(g) Net gains related to the sale of a building at our permanently closed Orange, Texas containerboard mill, miscellaneous land sales and other items that the Company does not believe are reflective of the Company's underlying operations recorded in net (gains) losses on fixed assets.

(h) Settlement associated with an Italian antitrust matter initially recorded as a special item in 2019 recorded in cost of products sold.

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

(j) Revision of severance estimates related to the Company's Build a Better IP initiative recorded in restructuring and other charges, net.

(k) Other-than-temporary impairment of an equity method investment recorded in equity earnings (loss), net of taxes.

(l) Interest income related to the settlement of the timber monetization restructuring tax matter recorded in interest expense, net.

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

Cash provided by operations, including discontinued operations, totaled approximately $1.7 billion and $1.8 billion for 2024 and 2023, respectively. The Company generated free cash flow of approximately $757 million in 2024 and $692 million in 2023. Free cash flow is a non-GAAP measure, which equals cash provided by operations less cash invested in capital projects, and the most directly comparable GAAP measure is cash provided by (used for) operations. Management utilizes this measure in connection with managing our business and believes that free cash flow is useful to investors as a liquidity measure because it measures the amount of cash generated that is available, after reinvesting in the

business, to maintain a strong balance sheet, pay dividends, repurchase stock, service debt and make investments for future growth. It should not be inferred that the entire free cash flow amount is available for discretionary expenditures.

The following are reconciliations of free cash flow to cash provided by operations:

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

LIQUIDITY AND CAPITAL RESOURCES

International Paper generated $1.7 billion of cash flow from operations for the year ended December 31, 2024, compared with $1.8 billion, including discontinued operations, in 2023. Capital spending for 2024 totaled $921 million, or 71% of depreciation and amortization expense. Our liquidity position remains strong, supported by approximately $1.9 billion of credit facilities.
