2025 Annual Report ‘25


 
A message from our CEO Dear Shareowners, Thank you for your confidence in our Company. In 2025, we advanced our multi‑year transformation with purpose and discipline, simplifying our portfolio, sharpening our regional focus, and strengthening our underlying earnings power. The acquisition of DS Smith created two regional sustainable packaging powerhouses, while the announced sale of our Global Cellulose Fibers business enables us to focus and invest as a packaging pure play. Most importantly, we reinforced our unwavering commitment to safety and accelerated our strategy to drive sustainable value creation through an advantaged cost position, stronger relative supply, and a world‑class customer experience. Guided by our 80/20 performance system, we concentrated our time, energy and investment on the highest-value opportunities across geographies, customers and products. Our actions in 2025 advanced our advantaged cost position and increased our ability to deliver consistent value for our customers. Through our disciplined focus, we executed $710 million of cost-out actions since 2024, which includes benefits that will be realized in 2026 and 2027. Our courageous actions strengthened our relative supply position and further enhanced our customer experience, which was reflected in improved and rising customer satisfaction. In North America, our results clearly demonstrate that our strategy is working. Despite a challenging environment, we delivered 37% year-over-year adjusted EBITDA growth supported by above-market volume growth in the second half of 2025, strong price realization and continued footprint optimization in our mills and converting plants. Significant investments in reliability, quality and sales capabilities further elevated our commercial performance, contributing to a 340-basis-point margin expansion and reinforcing our confidence in this business. In EMEA, we continued to advance our transformation with urgency and discipline. We have taken decisive action to simplify, segment, and integrate legacy DS Smith and legacy IP in the face of a weak market. While our EMEA business is in the early stages of transformation, we have a clear roadmap for commercial success and structural cost actions, and we expect to see the benefits accelerate throughout 2026. In January 2026, we took the next major step in our transformation by announcing our intention to create two independent, publicly traded companies — a North America–focused International Paper and a dedicated EMEA Packaging company. Looking ahead, each company will be positioned to win in distinct, competitive markets supported by focused leadership, tailored commercial strategies, independent balance sheets and flexible capital allocation aligned to attractive, but different, in-region opportunities. Powered by our 80/20 performance system, we believe both companies will be positioned to advance strategic priorities and deliver compelling long-term financial performance. We expect the spin-off of our EMEA business to be completed in 12-15 months. We are taking swift and decisive action to create long-term value for our shareowners. With a strong team, high-quality assets, and growing global demand for our products, International Paper is driving profitable growth and strengthening our position as the leader in sustainable packaging. We remain steadfast in our commitment to execute our transformation plan, to deliver a best-in-class customer experience and create value for our shareowners. As we embark on this next phase of our journey, I want to thank my colleagues for your dedication to IP. It is your courage, candor, and action that makes our future bright. It is through you that we earn the trust of our customers and our owners. Sincerely, Andrew K. Silvernail Chairman and Chief Executive Officer

PART I. ITEM 1. BUSINESS GENERAL DESCRIPTION OF BUSINESS International Paper Company (the "Company," "International Paper" or "IP", which may also be referred to as "we" or "us") is a global leader in sustainable packaging solutions. We produce renewable fiber-based packaging products with manufacturing operations in North America, Latin America, Europe and North Africa. We are a New York corporation, incorporated in 1941 as the successor to the New York corporation of the same name organized in 1898. In recent years, the Company has undergone significant transformation designed to simplify our operations, strengthen performance and position the business for long-term value creation. STRATEGY At International Paper, we follow the IP 80/20 performance system. The 80/20 approach is a disciplined, data-driven operating model focused on simplification, segmentation, resourcing and growth. In recent years the Company has taken actions to drive meaningful operational improvement and increase strategic flexibility across our global portfolio, including: Simplify Segment Resource Grow Focusing on our core business: sustainable packaging solutions Concentrating on the right geographies within each region Tailoring investment and capital allocation strategies to meet distinct needs Winning with customers and providing superior customer experiences Exiting non-core businesses Planning to separate into two independent, publicly traded companies in North America and EMEA (announced Jan 2026) Investing in greenfield packaging facilities; plans for two new plants announced in 2025 Enhancing investor base in both North America and EMEA Optimizing internal processes and organizational structures to reduce complexity Prioritizing the right customer segments and product offerings Investing in our talent and putting the right people in the right roles to create value Focusing on achieving an advantaged cost position We remain confident that the initiatives undertaken as part of our transformational journey will unlock substantial value at IP and strengthen the Company for our employees, customers and shareholders. 2025 Highlights • Financial: Net sales in 2025 totaled $23.63 billion and cash provided by operating activities totaled $1.7 billion. • Strategic Acquisition: Completed the acquisition of DS Smith Ltd. (“DS Smith”), advanced regional integration and implemented the 80/20 performance system within the new teams; enabled cross-business sharing of best practices. • Strategic Divestiture: Sold our Global Cellulose Fibers business for $1.5 billion to American Industrial Partners (completed January 2026). • Portfolio Rationalizations: Exited non-core businesses and markets, streamlined our footprint and redeployed resources where needed. • Organizational Improvements: Streamlined our organizational structure to eliminate redundancies created by the acquisition, further decentralized our teams, outsourced some functional areas and better resourced high value-creation areas. • Shareholder Returns: Returned $977 million to shareholders in dividends. • Packaging Focused Company: Took actions to position IP as a pure play company dedicated exclusively to sustainable packaging. 2026 Focus In 2026, we will continue to drive sustainable value creation and advance our company. Through the application of our 80/20 performance system, we will execute our strategy with a sharp focus on achieving an advantaged cost position, delivering superior customer experience and capturing a high relative supply position in the right geographies, with the right customers and the right product offerings. A critical priority will be the execution of the strategic separation to create two independent, publicly traded companies in North America and EMEA, which we aim to complete near the end of 2026 or early 2027. In North America, the business will continue strengthening its Table of Contents 1


 
position in the region, focusing on customers and leading on innovation with an advantaged cost position. In EMEA, we will prepare the business to stand alone as an independent, publicly traded entity following the separation with the goal of becoming the leading provider of innovative, sustainable packaging solutions in EMEA. From 2021 through 2025, International Paper’s capital expenditures totaled approximately $5.4 billion, excluding mergers and acquisitions. These expenditures reflect our continuing efforts to use our capital strategically to improve product quality and environmental performance, as well as lower costs, maintain reliability of operations and deploy strategic capital for capacity expansion. Capital expenditures in 2025 were approximately $1.9 billion and are expected to be approximately $2.0 billion to $2.1 billion in 2026. You can find more information about capital expenditures in Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations. Discussions of acquisitions can be found in Note 7 Acquisitions of Item 8. Financial Statements and Supplementary Data. You can find discussions of restructuring charges and other special items in Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations. For further discussion on our business strategies, see Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations. CURRENT BUSINESS OVERVIEW In the United States, as of the date of this filing, the Company operated 15 packaging mills, 159 converting and packaging plants and 15 recycling plants. Additionally, production facilities in Europe, North Africa and Latin America included 14 containerboard mills, 159 converting and packaging plants and 20 recycling plants. Substantially all our businesses have experienced, and are likely to continue to experience, cycles relating to industry capacity and general economic conditions. VALUES We are guided by our Company values: • Safety – Above all else, we care about people. We look out for each other to ensure everyone is physically and emotionally safe. • Ethics – We act honestly and operate with integrity and respect. We promote a culture of transparency and accountability. • Excellence – We set high expectations and deliver outstanding results for each other, our customers and our shareholders. SEGMENTS We operate under two divisions, which form the basis for the two segments we report, Packaging Solutions North America and Packaging Solutions EMEA. A description of these business segments can be found in Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations.

HUMAN CAPITAL EMPLOYEES As of December 31, 2025, we have approximately 62,602 employees, nearly 30,421 of whom are in the United States. Of our U.S. employees, 20,705 are hourly, with unions representing approximately 11,498 employees. Of this number, 8,622 are represented by the United Steelworkers union ("USW"). International Paper, the USW, and several other unions have entered into five master agreements covering various U.S. mills and converting facilities. Four of the master agreements are with the USW and include members from the International Association of Machinists and Aerospace Workers, International Brotherhood of Electrical Workers, United Food and Commercial Workers International Union and Workers Unite at certain U.S. mills and converting facilities. The Company also has a master agreement with District Counsel 2, which is affiliated with the Printing Packaging & Production Workers Union of North America that covers additional converting facilities. Individual facilities continue to have local agreements for subjects not covered by the master agreements. If local facility agreements are not successfully negotiated at the time of expiration, under the terms of the master agreements, the local agreements will automatically renew with the same terms in effect. In addition to our U.S. labor agreements, we operate manufacturing facilities across EMEA, where labor relations are governed by local laws, works councils, national unions, and country specific collective bargaining frameworks. Labor practices, employment protections, and negotiation processes in these regions can differ significantly from those in the U.S. and may impose additional requirements related to consultation, employee representation, and changes in operations. The Company works collaboratively with these local bodies and employee representatives, but labor related regulations, negotiations, or disruptions in any of these jurisdictions could impact operations, costs, or workforce flexibility. SAFETY AND WELLBEING At International Paper, we value safety above all else. The safety and well-being of our employees, visitors and business partners is fundamental to how we operate. In 2025, we reinforced our commitment to safety performance and further implemented our Safety Excellence strategy, which is designed to strengthen our safety culture across all operations. Our Board of Directors has oversight of our safety strategy, and in 2025 began receiving updates on our Safety Excellence efforts at every Board meeting, elevating safety as a standing governance priority and reinforcing accountability at the highest levels of the Company. In addition, in 2026 the Board participated in an intensive, in- person safety training led by our third-party safety consultant alongside senior management, further strengthening alignment on our Safety Excellence objectives and modeling the leadership behaviors we expect throughout the organization. Through our Safety Excellence efforts, we are building a culture guided by five key attributes: 1. We speak up and take action – every time, without fear. 2. We show up where the work happens and listen with intent. 3. We lead with humility and curiosity. 4. We proactively eliminate risk and invest in what matters. 5. We create a culture of care, trust, and accountability. To ensure lasting impact, in 2025 we continued engagement of a leading safety consultant and initiated comprehensive, top-down training and cascading through every level of leadership. Members of our executive teams actively participated in safety leadership training, personal coaching and in-field demonstrations, reinforcing accountability and modeling the behaviors we expect across the organization. These efforts are part of a broader plan to embed safety into every aspect of our operations, with additional initiatives scheduled for 2026 and 2027 to further advance our culture of safety excellence and engage every team member across IP. We believe that safety performance and operational performance are inextricably linked. Plants and mills that operate safely are less likely to experience unplanned process interruptions and downtime. The culture we are building to improve safety performance also improves asset reliability, enhances production stability and supports more consistent cost performance. Accordingly, the key drivers of strong safety performance contribute directly to Table of Contents 3


 
operational excellence and, in turn, to our financial results. Our focus on Safety Excellence is therefore both a cultural imperative and a key operational priority. Our goal is to achieve zero serious injuries and fatalities at all sites and see that everyone goes home safely at the end of each workday. This commitment means empowering every team member to stop unsafe work without hesitation. To advance this goal, the following endeavors were undertaken in 2025: • Trained 163 top leaders in 84 sessions that included classroom modules and coaching; • Began training 3,400 site level leaders through classroom modules and in-field coaching; • Established a Safety Governance Team in North America made up of executive leaders responsible for all North American operations; • Elevated safety updates as a standing agenda item at every meeting of the Board of Directors; • Executed targeted investments to sustainably reduce exposure to harm in our facilities; and • Celebrated team members who modeled our safety culture through personal recognition by our CEO and sharing stories across the enterprise, reinforcing a culture where safety leadership is valued and visible. We also believe workplace safety encompasses holistic well-being. We are committed to supporting the mental, emotional, physical, professional and financial well-being of our employees and their families. Through our Employee Assistance Program (“EAP”), offered at no cost to employees and family members, we provide resources such as counseling, well-being coaching, financial guidance, identity theft resolution and support for emotional and psychological safety. We believe these services help employees manage stress, build resilience, and achieve personal and professional goals. Our holistic approach to wellness also includes tools and guidance for incorporating wellness habits into daily life, ensuring our employees have the support they need to thrive. TALENT MANAGEMENT The attraction, retention and development of our employees is critical to our success. We strive to create a positive employee experience that begins at onboarding. Our Human Resources Talent Management Team hosts online Global New Employee Orientation for employees and each business conducts onsite new hire integration training unique to its business and/or facility. This experience continues through our continuous learning, development and performance management programs. We provide continuing education courses that are relevant to our industry and job functions within the Company, including both instructor-led and online training through our Learning Management System (“LMS”) MyLearning platform. Across the enterprise in 2025, employees completed nearly 830,000 learning activities through our platform. In addition, we have created learning paths for specific positions that are designed to encourage an employee’s advancement and growth within our organization, such as our REACH (Recruit, Engage, Align College Hires) program and Global Manufacturing Training Initiative programs. Through REACH we recruit and develop early- career engineers and safety professionals for our U.S. mills, preparing them to become future leaders. We invest in the growth and development of our employees by providing a multi-dimensional approach to learning that empowers, intellectually grows and professionally develops our employees. Our Global Manufacturing Training Initiative provides training services to hourly operations and maintenance employees in our mills in a standardized and structured manner. On the converting side of our business, nearly 100 front line and future leaders participated in our multi-day in-person Leadership Application and Professional Development and Manufacturing Management Associate Programs during 2025. We develop leaders through a broad range of LMS virtual and in-person resources, courses and workshops for individual contributors, people leaders and teams. In 2025, 44 senior leaders participated in the first offering of a multi-part workshop series developed in partnership with The Aspen Institute. The program focused on cultivating purpose-driven leadership, trust and collaboration, and equipping participants with the mindset and skills to navigate complexity and drive meaningful impact. We support employees in pursuing and preparing for future positions at the Company in several ways. We provide tuition reimbursement and student loan assistance to help employees repay qualified student loans. We also offer peer mentoring and leadership and career development training to support and develop our employees. These resources provide employees with the skills and support they need to achieve their career goals, build management skills and become leaders within our Company. Table of Contents 4


 
The labor market for both hourly and salaried workers continues to be competitive. For additional information regarding risks related to the current labor market, see Item 1A. Risk Factors – We operate in a challenging market for talent and may fail to attract and retain qualified personnel, including key management personnel. COMPENSATION AND BENEFITS We view compensation and benefits as part of how we attract, engage and retain our talented workforce. We do so by rewarding performance while ensuring competitive compensation in our local markets around the world. We continually evaluate our compensation and benefits so that we offer optimal compensation programs and remain a leading employer of choice in the areas in which we operate. TEAM-ORIENTED CULTURE At International Paper, we strive to create a high-trust, high-performance culture. We focus on promoting a culture that leverages the talents of all employees, and implementing practices that attract, recruit and retain a broad array of talent, guided by our ongoing dedication to equal employment opportunity for all. We believe our efforts will lead to improved business results, as teams with a broad range of perspectives drive innovation, enhance decision- making, and better reflect the markets we serve. We support enterprise-wide employee-led resource groups (“ERGs”) that are open to all employees and provide a forum to communicate and exchange ideas and build a network of relationships across the Company. Our ERGs are designed to help educate and motivate our global workforce, strengthening our business practices. The make-up of our Board of Directors reflects our efforts to seek the most qualified board candidates with a broad range of experiences and perspectives. Our Executive Leadership Team ("ELT") is currently comprised of our chief executive officer, two executive vice presidents and three senior vice presidents who oversee crucial functions and business units within the Company. By virtue of our secondary listing on the London Stock Exchange, International Paper is now subject to certain board composition disclosure requirements under the UK Listing Rules (the “UKLR”) established by the UK Financial Conduct Authority (the "FCA").

Following Ms. Flores's appointment, the number of women serving as members of executive management is 1 or 17%. COMMUNITY ENGAGEMENT Our community engagement efforts extend across the globe and support social and educational needs through charitable giving, volunteerism and product donations. We also partner with agencies to help communities prepare for and recover from natural disasters. In 2025, we invested approximately $16 million to address critical needs in the communities around the world where we work and live. INTELLECTUAL PROPERTY, PATENTS, AND TRADEMARKS We rely on a combination of patent, copyright, trademark, design, trade secret, and internet domain laws to establish and protect our intellectual property rights in the United States and in foreign jurisdictions. The Company’s practice is to file applications and obtain patents for products and services we believe improve our value proposition to customers. We maintain a portfolio of trademarks and service marks registered with the U.S. Patent and Trademark Office and in certain foreign jurisdictions, unregistered trademarks, licenses, and internet domain names that we consider important to the marketing of our products and business. These trademarks and service marks include those entity and product names that appear in this Annual Report on Form 10-K and our logo, as well as names of other products and marketing-related taglines. Our registered intellectual property has various expiration dates. The Company also relies on trade secret and other confidential information protection for manufacturing processes, product specifications, formulae, analyses, market information, forecasts, and other competitively sensitive information. COMPETITION AND COSTS The packaging sector is large and fragmented, and the areas into which we sell our principal products are very competitive. Our products compete with similar products produced by other forest products companies. We also compete, in some instances, with companies in other industries and against substitutes for wood-fiber products. Many factors influence the Company’s competitive position, including price, cost, product quality and services. You can find more information about the impact of these factors on operating profits in Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations. Table of Contents 6


 
MARKETING AND DISTRIBUTION The Company sells products directly to end users and converters, as well as through agents, resellers and distributors. DESCRIPTION OF PRINCIPAL PRODUCTS The Company’s principal products fall into several categories as described below and also in Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations. We produce renewable fiber-based packaging solutions, primarily servicing industrial consumer goods and e-commerce markets. The Company manufactures a broad range of containerboard and corrugated packaging products, which are used to protect, ship and display goods across diverse end-use categories. Our containerboard portfolio includes linerboard, medium, whitetop, and saturating kraft, which serve as the base materials for corrugated packaging. The Company converts containerboard into corrugated boxes, bulk bins, shipping containers and specialty packaging through its network of U.S. and international converting facilities. These products support customers in industries such as food and beverage, agriculture, industrial manufacturing, personal care pharmaceuticals and consumer goods. GOVERNMENTAL REGULATION The Company’s policy is to operate its mills and plants in compliance with all applicable laws and regulations such that it protects the environment and the health and safety of its employees. We operate our businesses and sell products globally. In each of the jurisdictions in which we operate, we are subject to a variety of laws and regulations governing various aspects of our business, including general business regulations as well as those governing the manufacturing, production, content, handling, storage, transport, marketing and sale of our products. Our operations are also subject to forestry reserve requirements, other environmental regulations and occupational health and safety laws. Violations can result in substantial fines, administrative sanctions, criminal penalties, revocations of operating permits and/or shutdowns of our facilities, litigation, other liabilities, as well as damage to our reputation. We incur costs to comply with these requirements. For additional information regarding risks associated with environmental matters, see Item 1A. Risk Factors – We are subject to a wide variety of laws, regulations and other governmental requirements that may change in significant ways, and the cost of compliance, or the failure to comply with such requirements, could impact our business and results of operations. ENVIRONMENTAL PROTECTION Our 2030 goals establish the foundation for our efforts to support healthy and abundant forests, strengthen communities, operate sustainably and advance renewable solutions. Through these efforts and more, the Company tackles the toughest issues in the value chain to improve its environmental footprint and promote the long-term sustainability of natural capital. Our approach to sustainability considers our entire value chain, from sourcing raw materials responsibly and working safely, to making renewable, recyclable products and providing a market for recovered products. To help inform and prioritize the focus of our sustainability strategy, we have engaged with internal and external stakeholders, assessed key issues, associated risks and opportunities, and incorporated sustainability considerations into our processes. The Company’s operations are subject to extensive and evolving federal, state, local, and international laws and regulations governing the protection of the environment and became more so in 2025 in light of our increased scale and global presence. Company manufacturing processes involve discharges to water, air emissions, water intake and waste handling and disposal activities, all of which are subject to a variety of environmental laws and regulations, along with requirements of environmental permits or analogous authorizations issued by various governmental authorities. Our continuing objectives include: (i) controlling emissions and discharges from our facilities to avoid adverse impacts on the environment, and (ii) maintaining compliance with applicable laws and regulations. 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"). For additional information regarding certain remediation actions, see Table of Contents 7


 
Note 14 Commitments and Contingent Liabilities of Item 8. Financial Statements and Supplementary Data. For additional information regarding risks associated with environmental matters, see Item 1A. Risk Factors – We are subject to a wide variety of laws, regulations and other governmental requirements that may change in significant ways, and the cost of compliance with such requirements, or the failure to comply with such requirements, could impact our business and results of operations. CLIMATE CHANGE The Company recognizes the impact of climate change on people and our planet. To manage climate-related risks, we are taking actions throughout our value chain to help advance a low-carbon economy. We aligned our annual sustainability reporting with the recommendations of the International Financial Reporting Standards S2 Climate- related Disclosures in the 2024 reporting cycle. As part of our climate reports, we identify and report on climate- related opportunities. We identify and evaluate physical and transition climate-related risks through our enterprise risk management process. The Company's 2024 Climate Report (which, prior to 2024, was referred to as the Company's Task Force on Climate-related Financial Disclosures Report or "TCFD Report") provides climate related disclosures as of December 31, 2024, consistent with the four core recommendations and 11 recommended disclosures set out in the June 2017 Final Report published by the TCFD (the "Final 2017 TCFD Report)". Our 2025 Climate Report, which will be available later in 2026, will provide climate related disclosures as of December 31, 2025, consistent with the four core recommendations and 11 recommended disclosures set out in the Final 2017 TCFD Report. For ease of review and given the detailed and technical content of these disclosures, the Climate Report is considered to be the most appropriate location for the disclosures. This statement is provided in accordance with UKLR 14.3.24R. Our corporate sustainability reports, including our 2024 and 2025 Climate Report, are or will be available at www.internationalpaper.com/reports. We transform renewable resources into recyclable products that people depend on every day. We aim to produce low carbon products that have a positive impact on nature. To this end, we source renewable fiber from responsibly managed forests and recycled raw materials. We then use a circular manufacturing process that makes the most of resources and byproducts, while reducing the environmental impacts of our operations. At the end of use, the majority of our low-carbon fiber-based products are recycled into new products at a higher rate than any other base material. We work to advance the shift to a low-carbon, circular economy by designing products that are 100% reusable, recyclable or compostable. Through improvements in operations, equipment, energy efficiency and fuel diversity, we are working to achieve company-wide reductions in Scope 1 and Scope 2 greenhouse gas (“GHG”) emissions. As part of our 2030 goals, we targeted incremental reductions of 35% in our Scope 1, 2, and 3 GHG emissions by 2030 in comparison to 2019 levels. We intend to continue to evaluate and implement projects as we pursue this 2030 GHG goal. This includes ongoing energy efficiency efforts and capital projects to phase out our most carbon intensive fuel sources (Scope 1) as well as developing GHG reduction strategies for our energy sourcing (Scope 2) and broader supply chain footprint (Scope 3). In addition, we were an early adopter of the Taskforce on Nature-related Financial Disclosures (“TNFD”). We published our first TNFD report in 2025 with 2024 data that aligns with TNFD recommendations, which have been designed to (i) meet the corporate reporting requirements of organizations across jurisdictions; (ii) be consistent with the global baseline for corporate sustainability reporting; and (iii) be aligned with the global policy goals outlined in the Kunming-Montreal Global Biodiversity Framework, which was adopted to halt and reverse nature loss by 2030. We use carbon-neutral biomass and manufacturing residuals to generate a majority of the manufacturing energy at our mills. We believe our efforts to advance sustainable forest management and restore forest landscapes are an important lever for mitigating climate change through carbon storage in forests. INTERNATIONAL EFFORTS The 2015 Paris Agreement compels international efforts and voluntary commitments toward reducing the emissions of GHGs. Although the United States has withdrawn from the 2015 Paris Agreement, IP recognizes the importance of global policy action to achieve emission reductions consistent with an increase of “well below 2 ° Celsius above pre-industrial levels and to pursue efforts to limit the temperature increase even further to 1.5 ° Celsius.” Consistent with this objective, participating countries aim to balance GHG emissions generation and sequestration in the second half of this century or, in effect, achieve net-zero global GHG emissions.

To assist member countries in meeting GHG reduction obligations, the European Union operates an Emissions Trading System ("EU ETS"). Our operations in the EU experience indirect impacts of the EU ETS through purchased power pricing. To date, neither the direct nor indirect impacts of the EU ETS have been material to the Company. We continue to evaluate potential future impacts in light of (i) our plans to separate our EMEA packaging business into an independent public company and (ii) ongoing developments in the global climate-policy frameworks, including the evolution of the 2015 Paris Agreement's non-binding national commitments and transparency framework. or allocation of, and market prices for, GHG credits. In 2025, many countries failed to submit updated climate targets, which has contributed to continued uncertainty in the allocation and market pricing of GHG credits. Additionally, the EU’s Corporate Sustainability Reporting Directive (“CSRD”), Corporate Sustainability Due Diligence Directive ("CSDDD") and Deforestation Regulation (“EUDR”), each impose additional compliance responsibilities on the Company. The CSRD requires additional reporting processes for greater accountability. The Company’s first reporting year under the CSRD is expected to be 2028. The CSRD standards replace the existing Non-Financial Reporting Directive and expand reporting requirements for companies operating in the EU. The implementation timeline varies depending on the type of entity. The CSDDD requires reporting and documentation about due diligence systems covering company and supply chains. The CSDDD became effective in 2024 and EU member states have two years to implement through national laws and decide on enforcement. The CSDDD implementation and compliance timeline may vary based on details once finalized by each member state. The EUDR requires companies trading in products derived from certain commodities to conduct extensive diligence on the value chain to ensure goods do not result from recent deforestation, forest degradation or breaches of local environmental and social laws. The Company is evaluating the implications of the EUDR to its business with expected reporting to begin after December 30, 2026. However, following the planned separation of our EMEA business into an independent public company, International Paper will review its obligations to report under these requirements. U.S. EFFORTS, INCLUDING STATE, REGIONAL AND LOCAL MEASURES Responses to climate change may result in regulatory risks as new laws and regulations aimed at reducing GHG emissions come into effect. The EPA manages regulations to: (i) control GHGs from mobile sources by adopting transportation fuel efficiency standards; (ii) control GHG emissions from new Electric Generating Units; (iii) control emissions from new oil and gas processing operations; and (iv) require reporting of GHGs from sources of GHGs greater than 25,000 tons per year. Several U.S. states have enacted or are considering legal measures requiring the reduction and reporting of GHG emissions by companies and public utilities. While current regulations in these jurisdictions have not had, and are not expected to have, a material impact on the Company, we continue to monitor developments closely. In particular, the State of California has enacted two laws that introduce expanded climate-related disclosure obligations: • California Climate Corporate Data Accountability Act (SB 253) requires annual public reporting of Scope 1 and Scope 2 GHG emissions, beginning with fiscal-year 2025 data to be disclosed by August 2026. • California Climate-Related Financial Risk Act (SB 261) mandates disclosure of climate-related reporting obligations on companies doing business in California meeting specified thresholds, subject to the resolution of ongoing legal challenges. In 2026, IP voluntarily self-reported under SB 261 using our 2024 Climate Report. The Company is actively preparing to meet the upcoming requirements of SB 261 and will continue to monitor state- level climate legislation, evaluate its implications on our operations and update disclosures as laws take effect and regularity clarity evolves. It is unclear what impacts, if any, future state-level or local GHG rules will have on the Company’s operations, as well as the outcome of any legal challenges to these rules. Table of Contents 9


 
SUMMARY Regulation related to GHGs and climate change continues to evolve in the areas of the world in which we do business. Because it remains unclear what actions regulators may take or when such actions may occur, it is not reasonably possible at this time to estimate the Company’s costs of compliance with rules that have not yet been adopted or implemented, may never be adopted or implemented or may be subject to legal challenge. In addition to possible direct impacts, future legislation and regulation could indirectly impact the Company. For example, higher prices for transportation, energy and other inputs, as well as more protracted air permitting processes, could cause delays and higher costs to implement capital projects. Other possible indirect impacts include influence on competitive position due to customer and end-consumer preferences regarding low-carbon, circular products with a high recycling rate along with tax credit and funding opportunities to expand green energy production and carbon credit generation. The Company has controls and procedures in place designed to track GHG emissions from our facilities and stay informed about developments concerning possible climate-related laws, regulations, accords, and policies where we operate. We regularly assess whether such developments may have a material effect on the Company, its operations or financial condition, and whether we have any related disclosure obligations under applicable rules and regulations. Moreover, compliance with legal requirements related to GHGs and/or climate change currently in effect or enacted in the future are expected to require future expenditures to meet GHG emission reduction, disclosure or other obligations. These obligations may include carbon taxes, the requirement to purchase GHG credits or the need to acquire carbon offsets. We may also incur significant expenditures in relation to our efforts to meet our internal targets or goals with respect to GHGs and climate change, including our 2030 goal on GHGs as discussed above. Furthermore, in connection with complying with legal requirements and/or our efforts to meet our internal targets and goals, we have made and expect to continue to make capital and other investments to displace traditional fossil fuels, such as fuel oil and coal, with lower carbon alternatives, such as biomass and natural gas. Rather than rely on carbon offsets, we focus on reducing energy consumption as well as relative GHG emissions across our mills and manufacturing facilities. Currently, these efforts and obligations have not materially impacted the Company, but such efforts and obligations may have a material impact on the Company in the future. We believe sustainability is a key element of corporate governance with oversight of management's initiatives and efforts provided by our Board of Directors and committees of the Board of Directors. Our Board of Directors has primary oversight of the Company's enterprise risk management program, which includes sustainability. The Board receives updates from our Chief Sustainability Officer ("CSO") and additional members of management. Our Board also conducts periodic reviews of components of the sustainability strategy and performance and reviews material key sustainability-related developments and issues. Our standing committees share responsibility for sustainability as described below: Audit and Finance Committee • Reviews processes and controls for external reporting of sustainability and social impact data and metrics. • Reviews related disclosures in Annual Report on Form 10-K and other sustainability reports. Governance Committee • Reviews and reassesses adequacy of, and oversees compliance with, our Corporate Governance Guidelines. • Seeks Board of Director candidates with a broad range of skills, experiences and perspectives. Public Policy and Environment Committee ("PPE Committee") • Reviews sustainability and social impact policies, plans and performance to ensure commitments to stewardship. • Stays current on emerging sustainability and social impact trends and issues impacting the Company. At the management level, ownership and governance of sustainability matters is embedded in the organization from the top down. Our CEO and ELT are responsible for corporate strategy and leadership including incorporation of our sustainability goals and standards into our daily operations and long-term business strategy. Our ELT, which is comprised of two executive vice presidents and three senior vice presidents who report directly to the CEO and oversee critical functions and business units within the Company, evaluates sustainability issues based on input from the businesses. The ELT receives several sustainability updates from our CSO. Table of Contents 10

RISK FACTORS The following is a summary of the material risks and uncertainties that could affect our business, financial condition and results of operations. You should read this summary together with the more detailed description of each risk factor contained below. Risks Related to Industry Conditions • Fluctuations in the prices of and the demand for our products due to factors such as economic cyclicality and changes in customer or consumer preferences, and government regulations. • Changes in the cost and availability of raw materials, energy and transportation have recently affected, and could continue to affect, our profitability. • Competition and downward pricing pressure in the global packaging industry could negatively impact our financial results. Risks Related to Market and Economic Factors • Maintenance of two exchange listings may adversely affect liquidity in the market for our shares of common stock and result in pricing differentials of shares of common stock between two exchanges. • Developments in general business and economic conditions could have an adverse effect on the demand for our products, our financial condition and the results of our operations. • Changes in international conditions or other risks arising from conducting business internationally could adversely affect our business and operations. Risks Related to our Operations • We are subject to a wide variety of laws, regulations and other government requirements that may change in significant ways, and the cost of compliance with such requirements, or the failure to comply with such requirements could impact our business and results of operations. • Material disruptions at one of our manufacturing facilities could negatively impact financial results. • We operate in a challenging market for talent and may fail to attract and retain qualified personnel, including key management personnel. • Our failure to maintain good employee or labor relations may affect our respective operations. • We may be unable to realize the expected benefits and costs savings associated with restructuring initiatives, including our 80/20 approach. • We may not achieve the expected benefits from strategic acquisitions, joint ventures, divestitures, spin-offs, capital investments, capital projects and other corporate transactions that are or will be pursued. • We are subject to cybersecurity and information technology risks related to breaches of security pertaining to sensitive company, customer, employee and vendor information as well as breaches in the technology used to manage operations and other business processes. • Our continued growth will depend on our ability to retain existing customers and attract new customers. • Uninsured losses or losses in excess of our insurance coverage for various risks could have an adverse financial effect on our business. Table of Contents 13


 
• We may not be able to adequately secure and protect our intellectual property rights, which could harm our competitive advantage. • We may fail to identify or leverage digital transformation initiatives. Risks Related to the Separation • The proposed separation of our EMEA packaging business may not be completed, on the currently contemplated timeline or at all. Risks Related to our Indebtedness • Changes in credit ratings issued by nationally recognized statistical rating organizations could adversely affect our cost of financing and have an adverse effect on the market price of our securities. • The level of our indebtedness could adversely affect our financial condition and impair our ability to operate our business. • We are subject to risks associated with variable rate debt. • Downgrades in the credit ratings of banks issuing certain letters of credit will increase our cost of maintaining certain indebtedness and may result in the acceleration of deferred taxes. Risks Related to Legal Proceedings and Compliance Costs • Results of legal proceedings could have a material effect on our consolidated financial results. • We could be exposed to liability for Brazilian taxes under our agreements with Sylvamo Corporation. • Failure to remediate a material weakness in DS Smith’s internal control over financial reporting could adversely affect our business and results of operations. Risks Related to Climate and Weather and Social and Environmental Impact Reporting • We are subject to risks associated with climate change and other sustainability matters and global, regional and local weather conditions as well as by legal, regulatory, and market responses to climate change. Risks Related to our Pension and Healthcare Costs • Our pension and health care costs are subject to numerous factors which could cause these costs to change. • Our pension plans are currently fully funded on a projected benefit obligation basis; however, the possibility exists that over time we may be required to make cash payments to the plan, reducing the cash available for our business. The Company faces a variety of risks, including risks in the normal course of business and through global, regional, and local events that could have an adverse impact on its reputation, operations, and financial performance. The following are material risk factors of which we are aware, including risk factors that could cause the Company’s actual results to differ materially from those contemplated in any forward-looking statement. If any of the events or circumstances described in any of the following risk factors occurs, our business, results of operations and/or financial condition could be materially and adversely affected, and our actual results may differ materially from those contemplated in any forward-looking statements we make in any public disclosures. Additional factors that could affect our business, results of operations and/or financial condition are discussed elsewhere in this Annual Report on Form 10-K (including in Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations) and in the Company’s other filings with the U.S. Securities and Exchange Commission. RISKS RELATED TO INDUSTRY CONDITIONS Fluctuations in the prices of and the demand for our products due to factors such as economic cyclicality and changes in customer or consumer preferences, and government regulation could materially affect our financial condition, results of operations and cash flows. Substantially all of our business has experienced, and is expected to continue to experience, cycles relating to industry capacity, customer demand, and general economic conditions. The length and magnitude of these cycles have varied over time and by product. Product prices and sales volumes have fallen in the past, and there can be no assurance that this will not recur. New or existing producers of paper and sustainable packaging products may add or adjust capacity affecting available supply. Further, changes in customer or consumer preferences may increase or decrease the demand for fiber-based products and non-fiber substitutes. Customer and consumer Table of Contents 14


 
preferences change based on, among other factors, cost, convenience, health concerns and perceptions and an increased awareness of sustainability considerations. In some areas, customers have increasingly shown interest in environmentally friendly products such as fiber-based packaging. Advances in non-fiber technologies such as plastic packaging or other materials could result in decreased demand for our products. In addition, legal developments, such as new governmental regulations on single-use packaging products could significantly alter the market for our products. Any of the foregoing, including a failure to anticipate and respond to changing trends, customer preferences and technological and regulatory developments, could have a material adverse effect on our business, financial condition, results of operations and/or future prospects. A lack of investor confidence in the paper and packaging industry could also have a negative impact on our business, financial condition, results of operations and/or future prospects. Changes in the cost and availability of raw materials, energy and transportation have recently affected, and could continue to affect, our profitability. We rely heavily on the use of certain raw materials (principally virgin wood fiber, recycled fiber, caustic soda, starch and adhesives), energy sources (principally biomass, natural gas, electricity and fuel oil) and third-party transport companies. The market price of virgin wood fiber varies based on availability, demand, quality, and source. The global supply and demand for recycled fiber may be affected by factors such as trade policies between countries, individual governments’ legislation and regulations, and general macroeconomic conditions. In addition, the increase in demand of products manufactured, in whole or in part, from recycled fiber, on a global basis, may cause significant fluctuations in recycled fiber prices. Taking into account ongoing inflationary conditions in domestic and global markets, we have experienced, and may continue to experience, a significant increase in various costs, including recycled fiber, energy, freight, chemical, and other supply chain costs, which has adversely affected, and may continue to adversely affect, our operations. Moreover, the availability of labor and the market price for fuel may affect third-party transportation costs. In addition, because our business operates in highly competitive industry segments, we have not always been able to, and may in the future be unable to, recoup past or future increases in the costs of any raw materials, energy sources or transportation sources from customers, which significantly affect profitability. In addition, where we are able to recoup our cost increases, there may be a delay between the onset of the cost increases and the recoupment. Any inability to recover input cost increases could lead to a material adverse effect on our business, financial condition, results of operations and/or future prospects. We have significant exposure to energy costs, in particular gas, electricity and other fuel costs. Energy prices have fluctuated dramatically in the past and may continue to increase and/or fluctuate in the future. Transportation costs are also impacted by energy costs since a key component of transportation costs relates to the cost of oil. We have employed and expect to continue to employ, strategies, including hedging a portion of our energy costs, and risk mitigation tools to reduce the volatility of energy costs and ensure a degree of certainty over future energy costs. However, there can be no certainty that those strategies and tools will continue to manage such impact in the future. Volatile and increasing energy prices, including as a consequence of the conflict between Russia and Ukraine as well as heightened geopolitical tensions in regions such as the Middle East, China, and recent events in Venezuela, or a failure to effectively implement such strategies and tools could have a material adverse effect on our business, financial condition, results of operations and/or future prospects. Competition and downward pricing pressure in the global packaging industry could negatively impact our financial results. We operate in a competitive international environment. Our products compete with other forest products and packaging companies in the markets where we operate. Product innovations, manufacturing and operating efficiencies, additional manufacturing capacity, distribution and commercial strategies pursued or achieved by competitors, and the entry of new competitors, could negatively impact our financial results. In addition, our products compete with companies that produce substitutes for wood- fiber products, such as plastics and various types of metal. Customer shifts away from wood-fiber products toward such substitute products may adversely affect our business and financial results. Further, we depend on critical suppliers and key customers. An inability to foster these relationships and to manage any material changes in commercial terms and service levels could have a material adverse impact on our business, financial condition, results of operations and/or future prospects. Table of Contents 15


 
Pricing in the paper and packaging industries can be affected by, among other things, product commoditization, changes in demand, entrance or withdrawal of new competitors or capacity, changes in product supply, and the introduction of new products, technologies and equipment, including the use of artificial intelligence ("AI") and machine learning solutions. We face significant pressure to reduce per unit costs to achieve commercially acceptable returns. In circumstances where we are unable to adjust the relevant cost base sufficiently, pricing pressure could have a material adverse effect on our business, financial condition, results of operations and/or future prospects. RISKS RELATED TO MARKET AND ECONOMIC FACTORS Our maintenance of two exchange listings may adversely affect liquidity in the market for our shares of common stock and result in pricing differentials of shares of common stock between the two exchanges. Trading in shares of common stock on the London Stock Exchange ("LSE") and the NYSE takes place in different currencies (pound sterling on the LSE and U.S. dollars on the NYSE) and at different times (resulting from different time zones, different trading hours and different trading days for the LSE and the NYSE). The trading prices of shares of common stock on these two exchanges may at times differ due to these and other factors. Any decrease in the price of shares of common stock on the NYSE could cause a decrease in the trading price of shares of common stock on the LSE and vice versa. The benefits we expect of the dual listing on the NYSE and the LSE, which are increased liquidity, visibility among investors and access to investors who may be able to hold listed shares in the United Kingdom, but not the United States, and vice versa, may not be realized or, if realized, may not be sustained, and the costs and additional regulatory burdens associated with a dual listing may ultimately outweigh the associated benefits. We are affected by developments in general business and economic conditions, which could have an adverse effect on the demand for our products, our financial condition and the results of our operations including our ability to pay a cash dividend. General economic conditions may adversely affect industrial non-durable goods production, consumer confidence and spending, and employment levels, all which impact demand for our products, or otherwise adversely affect our business. We may also be adversely affected by catastrophic or other unforeseen events, natural disasters, geopolitical events, military conflicts, terrorism, port and canal blockages and similar disruptions, political, financial or social instability, or civil or social unrest. Future health epidemics or pandemics could also adversely impact portions of our business to varying degrees, including as the result of change in demand for certain products, supply chain and labor disruptions, and higher costs. These effects could have a material impact on our business, results of operations, cash flow, liquidity, or financial condition. Moreover, negative economic conditions or other adverse developments with respect to our business have resulted in and may in the future result in impairment charges, including impairments related to divested or acquired businesses whose carrying values may not be recoverable, any of which could be material. Volatility or uncertainty in the financial, capital and credit markets, and negative developments associated with interest rates, asset values, currency exchange rates and the availability of credit, could also have a material adverse effect on our business, financial condition and results of operations and could adversely affect our liquidity, access to capital markets and ability to pay a dividend. Macroeconomic conditions in the U.S., Europe and globally remain challenging and volatile. Recent periods have been characterized not only by persistent inflationary pressures, elevated interest rates, challenging labor market conditions, tariff policies and heightened trade policy uncertainty but also by slowing global economic growth, weakening global trade and investment flows, supply chain realignments, currency volatility, shifting fiscal and monetary policies across major economies and adverse effects and uncertainty associated with current geopolitical conditions. Our operations have been adversely affected and could continue to be adversely affected in the future, by these challenging macroeconomic and geopolitical conditions, including as the result of lower demand for certain products, and higher raw material and labor costs. Further, because the markets for packaging products in many industrialized countries are generally mature, there is a significant degree of correlation between economic growth and demand for packaging products. Therefore, any deterioration in macroeconomic conditions in the U.S., Europe and/or globally resulting in a slowdown in economic growth may correlate with a corresponding decline in demand for packaging products in those markets. Moreover, any significant deterioration in current negative macroeconomic conditions, or any recovery therefrom that is significantly slower than anticipated, could have a material adverse effect on our business, results of operations or financial condition. In addition, there can be no assurance that Table of Contents 16


 
dividends will continue to be declared or paid at historical levels, and any reduction or suspension of dividends could negatively impact our stock price. Further, if negative macroeconomic conditions result in significant disruptions to capital and financial markets, the cost of borrowing, our ability to access capital on favorable terms, and our overall liquidity could be adversely affected. Changes in international conditions or other risks arising from conducting business internationally could adversely affect our business and operations. As a global producer of renewable fiber-based packaging products, we operate in many different countries. As a result, we are vulnerable to risks related to our international operations. These risks, which can vary substantially by country, may include economic or political instability, geopolitical events, corruption, anti-American sentiment, expropriation measures, social and ethnic unrest, natural disasters, military conflicts and terrorism, the regulatory environment (including the risks of operating in developing or emerging markets in which there are significant uncertainties regarding the interpretation and enforceability of legal requirements and the enforceability of contractual rights and intellectual property rights), adverse currency fluctuations, foreign exchange control regimes (including restrictions on currency conversion), downturns or changes in economic conditions (including in relation to commodity inflation), adverse tax consequences or rulings, import restrictions, controls or other trade protection measures, economic sanctions, health guidelines and safety protocols, nationalization, changes in social, political or labor conditions, and adverse developments regarding sustainability, environmental regulations and trade policies and agreements, any of which risks could negatively affect our financial results. For example, a portion of our sales could be adversely affected by changes in economic conditions and demographics, including as a result of tariffs. Trade protection measures in favor of local producers of competing products, including governmental subsidies, tariffs, tax benefits and other measures may give local producers a competitive advantage and adversely impact our operating results and our business prospects in these countries. Likewise, disruption in existing trade agreements or increased trade friction between countries (such as in relation to the trade tensions between the U.S. and China), could have a negative effect on our business and results of operations by restricting the free flow of goods and services across borders. Additionally, the U.S. government in 2025 increased certain rates and broadened the scope of certain tariffs imposed on goods imported into the U.S., such as from China, which may strain international trade relations and increase the risk that foreign governments implement retaliatory tariffs on goods imported from the United States. Specifically, the U.S. federal government implemented tariffs on certain foreign goods and may implement additional tariffs on foreign goods. If lasting, such tariffs and any further legislation or actions taken by the U.S. federal government that restrict trade, such as additional tariffs, trade barriers, and other protectionist or retaliatory measures taken by governments in Europe, Asia, and other countries, could adversely impact our ability to sell products and services in our international markets. Tariffs have increased the cost of certain capital items, including materials and equipment used in our capital investments. These increased costs could adversely impact the profit margin that we earn on our products, which could make our products less competitive and reduce consumer demand. Countries may also adopt other protectionist measures that could limit our ability to offer our products and services. Conversely, these tariffs and retaliatory tariffs may be subject to further changes or negotiations which could lower or remove them in the near or longer term with a return to more normalized trade conditions in some instances. Due to this uncertainty, the ultimate impact of any tariffs and trade tension is unclear and will depend on various factors, including if there are negotiated bilateral agreements to remove or lower tariffs, and the timing, amount, scope and nature of the tariffs that remain implemented. Recent legal and policy developments have further increased uncertainty. On February 20, 2026, the U.S. Supreme Court struck down several of the sweeping tariffs imposed through a series of executive orders, holding that the tariffs exceeded the authority granted under the International Emergency Economic Powers Act. The Court's ruling eliminated key tariffs on imports from numerous major trading partners and created uncertainty regarding the status of various trade agreements and tariff related obligations. The Court did not determine whether importers are owed refunds for tariffs previously paid, although estimates suggest that potential refunds could be substantial, and federal agencies must now determine how to administer the ruling. In response to the Supreme Court’s decision, the government announced new Executive Orders on February 20, 2026, aimed at restructuring U.S. tariff policy and exploring alternative statutory authorities to impose or maintain tariffs. The scope, timing, and implementation of these Executive Orders remains uncertain, and may result in new or modified tariff regimes, additional regulatory requirements, or further trade friction with U.S. trading partners. We may become entitled to refunds of certain tariffs previously paid; however, whether any refund will be available, and the amount and timing of any such refund, remain uncertain and subject to ongoing administrative processes and additional federal guidance. We are continuing to evaluate the impact of both the Supreme Court’s ruling and the new Executive Orders on our supply Table of Contents 17


 
chain, input costs, pricing, capital investments, and overall operating results, and the ultimate impact, if any, on our business is not yet known. We may continue to be adversely affected by ongoing geopolitical instability and the economic consequences and disruptions arising therefrom, including as the result of the military conflict between Russia and Ukraine, the conflict in the Middle East, and increasing tensions between China and Taiwan. These risks may be further heightened in the event of the expansion in the scope or escalation of any such conflicts. In addition, changes to economic sanctions programs, could put us at risk of violating sanctions because of an existing presence in a newly sanctioned jurisdiction or relationship with a newly sanctioned entity if we fail or are unable to end such presence or relationship in a timely manner. In addition, our international operations are subject to laws related to operations in foreign jurisdictions, including laws prohibiting bribery of government officials and other corrupt practices. Anti-bribery laws such as the U.K. Bribery Act 2010, the Foreign Corrupt Practices Act of 1977, and similar worldwide anti-corruption laws generally prohibit companies and their intermediaries from making improper payments to public officials for the purpose of obtaining or retaining business. Further, the U.S. Department of the Treasury’s Office of Foreign Assets Control and other non-U.S. government entities maintain economic sanctions targeting various countries, persons and entities. We are also subject to the laws and regulations of governmental and regulatory agencies. Failure to comply with domestic or foreign laws could result in various adverse consequences for us including the imposition of civil or criminal sanctions, reputational damage and the prosecution of executives overseeing international operations. We are exposed to the translation of the results of overseas subsidiaries into their respective reporting currencies, as well as the impact of currency fluctuations on their commercial transactions denominated in foreign currencies. Adverse movements in foreign exchange rates relating to foreign currency denominated commodities, assets and liabilities, and transactions could have a material impact on our business, financial condition, results of operations and/or future prospects. RISKS RELATED TO OUR OPERATIONS We are subject to a wide variety of laws, regulations and other government requirements that may change in significant ways, and the cost of compliance with such requirements, or the failure to comply with such requirements, could impact our business and results of operations. As a publicly listed company, we are subject to the reporting requirements of the Exchange Act and the Sarbanes- Oxley Act of 2002 (the “Sarbanes-Oxley Act”), and the listing requirements of the NYSE. By virtue of our secondary listing on the LSE, we are also subject to the listing requirements of the LSE, the Market Abuse Regulation and Disclosure Guidance and Transparency Rules. The Exchange Act requires that we file annual and other reports with respect to our business, financial condition and results of operations. The Sarbanes-Oxley Act requires, among other things, that we establish and maintain effective internal controls and procedures for financial reporting. Any failure to maintain effective controls or any difficulties encountered implementing required new or improved controls could cause us to fail to meet our reporting obligations, which could have a material adverse effect on our business and the trading price of our common stock. Our operations are subject to regulation under a wide variety of domestic and international laws, regulations and other government requirements, including, among others, those relating to the environment, health and safety, labor and employment, data privacy, tax, trade, competition and corruption and health care. There can be no assurance that laws, regulations and government requirements will not be changed, applied or interpreted in ways that will require us to modify our respective operations and objectives or affect our respective returns on investments by restricting existing activities and products or increasing costs. In addition, any failure or alleged failure to comply with applicable laws, regulations or other government requirements could have an adverse effect on our reputation and financial results or may result in, among other things, litigation, revocation of required licenses, internal investigations, governmental investigations or proceedings, administrative enforcement actions, fines and civil and criminal liability. We are subject to increasingly stringent federal, state, local and international laws governing the protection of the environment that continue to evolve as new guidance is provided by regulatory and governing bodies and as pending or future litigation is resolved. The changing laws, regulations and standards relating to corporate governance, sustainability matters and public disclosures in various jurisdictions create uncertainty for public Table of Contents 18


 
companies, increase legal and compliance costs and make activities more time consuming. We have incurred, and, following completion of our planned separation of the EMEA packaging business, expect to continue to incur and invest resources, significant capital, operating and other expenditures complying with applicable and forthcoming environmental laws and regulations, including with respect to GHG emissions and other climate-related matters. These investments may lead to higher operating expenses as the cost of compliance increases. Our environmental expenditures include, among other areas, those related to air and water quality, waste disposal and the cleanup of soil and groundwater, including situations where we have been identified as a potentially responsible party. Following the separation of our EMEA packaging business, we will evaluate our exposure to international climate regulations. There can be no assurance that future remediation requirements and compliance with existing and new laws and requirements will not require significant expenditures, or that existing reserves for specific matters will be adequate to cover future costs. We could also incur substantial fines or sanctions, enforcement actions (including orders limiting operations or requiring corrective measures), natural resource damages claims, cleanup and closure costs, third-party claims for property damage and personal injury and reputational harm as a result of violations of, or liabilities under, environmental laws, regulations, codes and common law. The amount and timing of environmental expenditures is difficult to predict, and, in some cases, liability may be imposed without regard to contribution or to whether we knew of, or caused, the release of hazardous substances. Additionally, if our compliance efforts with new applicable laws, regulations, and standards do not align with the expectations of regulatory or governing bodies due to ambiguities in their application and implementation, or if they differ from interpretations arising from related litigation, we may face legal actions. This could negatively impact our business, financial condition, operational results, and cash flow. Our global operations are subject to complex and evolving domestic and international data privacy laws and regulations, such as the European Union’s General Data Protection Regulation, the UK's General Data Protection Regulation, any supplemental applicable European Union member state or UK national data protection laws, China’s Personal Information Protection Law and comprehensive privacy laws in many U.S. states. These laws impose a range of compliance obligations regarding the handling of personal data. There are significant penalties for non-compliance, including monetary fines, disruption of operations and reputational harm. Moreover, other states and governmental authorities around the world have introduced or passed, or are considering, similar legislation which may impose varying standards and requirements on data collection, use and processing activities. This increasingly restrictive and evolving global regulatory environment related to data privacy and data protection may continue to require changes to our business practices, and give rise to significantly expanded compliance burdens, costs and enforcement risks. Moreover, many of these laws and regulations are subject to uncertain application, interpretation or enforcement standards that could result in claims, changes to business practices, data processing and security systems, penalties, increased operating costs or other impacts on our business. Additionally, regulatory bodies and others tasked with enforcing privacy and data protection laws have been actively engaging in enforcement investigations and actions. These laws often provide for civil penalties for violations, as well as private rights of action for data breaches that may increase data breach litigation. We use internal and external resources to monitor compliance with relevant legislation and continually evaluate and, where necessary, modify data processing practices and policies to comply with evolving privacy laws. Nevertheless, relevant regulatory authorities could determine that our data handling practices fail to address all the requirements of certain new laws, which could subject us to penalties and/or litigation. In addition, there is no assurance that our security controls over personal data, the training of employees and vendors on data privacy and data security, and policies, procedures and practices will prevent the improper handling of, disclosure of or access to personal data. Any such unauthorized access, use or disclosure in violation of applicable privacy and data protection laws could cause reputational harm and loss of consumer confidence and subject us to government enforcement actions (including fines), or result in private litigation, which could result in loss of revenue, increased costs, liability for monetary damages, fines and/or criminal prosecution, all of which could negatively affect our business and operating results. We are also exposed to the risk of changes in tax law and tax rates in a number of jurisdictions. The costs associated with these laws and regulations are substantial and possible future laws and regulations or changes to existing laws and regulations (including the imposition of higher taxes) could require us to incur additional expenses or capital expenditures or result in restrictions on or suspensions of operations. For example, the Organization for Economic Cooperation and Development (the “OECD”) has issued a framework pursuant to which EU and non-EU countries (including countries in which we operate) have enacted a 15% global minimum tax applied on a country- by-country basis (the “Pillar Two rule”). In many of the countries implementing the Pillar Two rule, the first component of the Pillar Two rule became effective in 2024 and the second component in 2025. In January 2026, the Table of Contents 19


 
OECD/G20 issued administrative guidance modifying application of the Pillar Two rule through a Side-by-Side system introducing two new Pillar Two safe harbors for US-parented multinational corporations, effective beginning in 2026. The application of these safe harbors by each country that has implemented Pillar Two now depends on the respective countries’ enacting the Side-by-Side system. It is possible that the Pillar Two rule could adversely impact our effective tax rate in future periods. Additionally, administrative guidance with respect to tax law can be incomplete or vary from legislative intent, and therefore the application of the tax law is uncertain. While we believe our reported positions comply with relevant tax laws and regulations, taxing authorities could interpret the application of certain laws and regulations differently. We have been and continue to be subject to tax audits in various taxing jurisdictions around the world. In some cases, we have appealed, and may continue to appeal, assessments by taxing authorities, including in the court system. As such, tax controversy matters may result in previously unrecorded tax expenses, accelerated cash tax payments, higher future tax expenses, or the assessment of interest and penalties. AI continues to evolve rapidly, and, as with many technological innovations, it presents risks and challenges that could affect its adoption and our business. Uncertainty in the global and legal regulatory regime relating to AI may require significant resources to modify and maintain business practices to comply with international laws, the nature of which cannot be determined at this time. Multiple jurisdictions, including Europe, the U.S. federal government, and certain U.S. states, have already proposed or enacted laws, regulations, and other requirements governing AI. In Europe, the EU AI Act, adopted in May 2024, entered its implementation phase in 2025 and imposes extensive transparency, risk management and data governance obligations for AI systems, particularly those classified as high risk, with significant fines for noncompliance. Additional implementing measures are expected. In the United States, 2025 marked a shift in federal AI policy with the government establishing a national AI policy framework aimed at asserting federal preemption over divergent state AI laws. States continue to adopt AI statutes creating varied compliance regimes addressing accountability, automated decision-making, transparency, worker protections and privacy. Changes in regulatory regimes, or the adoption of new or more restrictive requirements, could make it more difficult to use AI tools, require us to change our business practices, or limit AI usage which may lead to inefficiencies or competitive disadvantages. Material disruptions at one of our manufacturing facilities could negatively impact financial results. We operate facilities in compliance with applicable rules and regulations and take measures to minimize the risks of disruption. A material disruption at our corporate headquarters, a manufacturing facility or key mill could prevent us from meeting customer demand, reduce sales and/or negatively impact our financial condition. Any of our manufacturing facilities or any machines within an otherwise operational facility, could cease operations unexpectedly due to a number of events, including: • adverse weather events like fires, floods, earthquakes, hurricanes, winter storms and extreme temperatures, or other catastrophes (including adverse weather conditions that may be intensified by climate change); • the effect of a drought or reduced rainfall on its water supply; • disruption in the supply of raw materials or other manufacturing inputs; • terrorism or threats of terrorism, security incidents or other threats to employee safety; • information system disruptions or failures due to any number of causes, including cyber-attacks; • domestic and international laws and regulations applicable to us and any of our respective business partners, including joint venture partners, around the world; • unscheduled maintenance outages; • prolonged power failures; • an equipment failure; Table of Contents 20


 
• a chemical spill or release; • explosion of a boiler or other equipment; • damage or disruptions caused by third parties operating on or adjacent to a manufacturing facility; • disruptions in the transportation infrastructure, including roads, bridges, railroad tracks and tunnels; • a widespread outbreak of an illness or any other communicable disease, or any other public health crisis or any impacts related to government regulation as a result thereof; • failure of third-party service providers and business partners to satisfactorily fulfill their commitments and responsibilities in a timely manner and in accordance with agreed upon terms; • labor difficulties; and • other operational problems. Any such downtime or facility damage could prevent us from meeting production targets, customer demand and satisfying customer requirements, which may necessitate unplanned expenditures, resulting in lower sales and have a negative effect on our financial results. We operate in a challenging market for talent and may fail to attract and retain qualified personnel, including key management personnel. Our ability to operate and grow our business depends on our ability to attract and retain employees with the skills necessary to operate and maintain our facilities, produce our products and serve our customers. The market for both hourly workers and salaried workers continues to be competitive, particularly for employees with specialized technical and trade experience. This, along with the current competitive labor market and ongoing cost-pressured conditions, has led to higher labor costs. In addition, we rely on our key executive and management personnel to manage our business efficiently and effectively. The unanticipated departure of key executive and management employees, particularly in a challenging market for attracting and retaining employees, could adversely affect our business. Moreover, changing demographics and labor work-force trends, including evolving expectations around remote and hybrid work, work-life balance expectations and increased return-to-office requirements, may make it difficult for us to attract, retain or replace retiring or departing employees. The failure to retain and/or recruit additional or substitute senior managers and/or other key employees and a failure to identify and resource for future capability requirements such that there is a gap in skills and knowledge across key business areas, or if higher labor costs and shortages persist, could have a material adverse effect on our business, financial condition, results of operations and/or future prospects. Our failure to maintain good employee or labor relations may affect our respective operations. Future developments in relation to our business could adversely affect employee or labor relations. Good employee and labor relations depend on the ability to drive innovation, manage change and engage the workforce, and failure to do so could have a material adverse effect on our business, financial condition, results of operations and/or future prospects. Further, labor disputes or other problems could lead to a substantial interruption to our business and have a material adverse effect on our business, financial condition, results of operations and/or future prospects. A significant number of our employees located outside of the U.S. are represented by unions, trade unions and national works councils. We have collective bargaining agreements in place with U.S. and international trade unions. In the U.S., we may not be able to successfully negotiate new collective bargaining agreements once our current contracts with unions expire without work stoppages or labor difficulties, or we may be unable to renegotiate such contracts on favorable terms. The mill master collective bargaining agreement and related mill joint pension council master agreement with the United Steelworkers union (the "USW") will expire in August 2027 and September 2027, respectively. The converting master collective bargaining agreements and related converting joint pension council master agreement which will expire in April and September 2028, respectively. The USW represents approximately 8,622 employees in our mills and converting facilities. In Europe, we have collective agreements in place with trade unions, and also have agreements in place with the European Works Council, which brings together employee representatives from the different European countries in which we operate and provides a forum Table of Contents 21


 
for information sharing and consultation. We have experienced limited work stoppages in the past and may experience work stoppages in the future. Further, labor organizations may attempt to organize groups of additional employees from time to time, and recent and potential changes in labor laws could make it easier for them to do so. If there is a substantial change to the terms of any collective bargaining agreements or an agreement acceptable to us cannot be reached at all when the collective agreements are renewed, we could face increased labor costs or disruptions as a result of labor union activity in the future. If we experience any extended interruption of operations at any of the relevant facilities as a result of strikes or other work stoppages, or if unions, trade unions and national works councils are able to organize additional groups of our employees, our operating costs could increase and our operational flexibility could be reduced. We may be unable to realize the expected benefits and cost savings associated with restructuring initiatives, including our 80/20 approach. We have restructured portions of our operations from time to time and have current restructuring initiatives taking place and planned for North America and EMEA. In 2025, we agreed to sell our Global Cellulose Fibers business, which we completed in January 2026, and exited the converting bag business. In North America, we actioned closure of three mills, two recycling facilities, and six box plants, as well as one sheet plant, one sheet feeder, one molded fiber facility and one box-to-sheet-feeder conversion. In EMEA, we actioned closures of 17 packaging plants, one mill and one recycling center. Together these actions reduced the workforce by approximately 1,400. On January 29, 2026, we announced plans to separate our EMEA packaging business into an independent public company. Through the 80/20 approach, we intend to deliver profitable market share growth by striving to be the lowest-cost producer, and the most reliable and innovative sustainable packaging solutions provider to our customers across North America and EMEA. As part of our 80/20 approach, we intend to guide investments and align resources to win with customers, while reducing complexity and cost across the Company. To that end, we have been implementing restructuring initiatives. To that end, we have incurred, and expect to incur, charges in connection with our restructuring initiatives. We may be unable to realize the expected benefits from these and other restructuring initiatives that we may in the future undertake. In particular, restructuring activities may divert the attention of management, disrupt operations and fail to achieve the intended cost and operational benefits. If the Company is unable to realize the expected benefits from its restructuring initiatives, the Company’s financial results could be adversely impacted. In addition, because we are unable to predict or control market conditions, including changes in the supply and demand for our products, product prices or manufacturing costs, we may not be able to predict the appropriate time to undertake restructurings. Further, cash and non-cash charges may be incurred in connection with restructuring activities, which may be material. Moreover, judgment is required to estimate restructuring charges, and these estimates, and the assumptions underlying them, may change as additional information becomes available or facts or circumstances related to restructuring initiatives change. We may not achieve the expected benefits from strategic acquisitions, joint ventures, divestitures, spin- offs, capital investments, capital projects and other corporate transactions that are or will be pursued. Our strategy for long-term growth, productivity and profitability depends, in part, on our ability to accomplish prudent acquisitions, joint ventures, divestitures, spin-offs, and other strategic corporate transactions and to realize the benefits expected from such transactions, including the planned separation of our EMEA packaging business. Ongoing capital investment is also required to expand, maintain and upgrade existing facilities, to develop new facilities and to ensure compliance with new regulatory requirements. As part of our 80/20 approach, our capital spending has increased. Capital projects may experience unanticipated disruptions or delays and the desired benefits from those projects may not be realized. These risks include a deterioration in macroeconomic conditions, shortages or higher costs of capital equipment or materials, delays in obtaining permits or other required approvals, changes in laws and regulations or operational challenges. Our ability to advance capital investments depends on the availability of cash flow. If our cash flow decreases due to market conditions, increased operating costs, tightening credit markets, or other factors, we may be required to defer, scale back or cancel planned capital projects. Such delays or reductions could limit our ability to pursue our strategic priorities, maintain or improve operational efficiency or respond effectively to competitive or regulatory pressures. We are subject to the risk that the expected benefits from such transactions and capital investments may not be achieved. This failure could require an impairment charge to be recorded for goodwill or other intangible assets, which could lead to decreased assets and reduced net earnings. Among the benefits expected from the strategic separation of our EMEA packaging business, as well as completed acquisitions and joint ventures are synergies, cost savings, growth Table of Contents 22


 
opportunities and access to new markets (or a combination thereof), and in the case of divestitures, the realization of proceeds from the sale of businesses and assets to purchasers who place a higher strategic value on such businesses and assets. Corporate transactions of this nature that we may pursue involve a number of special risks, including with respect to the inability to realize business goals with such transactions as noted above, including our assumptions, the focus of management’s attention on these transactions, the assimilation or separation of businesses, the demands on financial, operational and information technology systems, our ability to integrate and separate personnel, labor models, financials, customer relationships, supply chain and logistics, IT and other systems successfully, business culture compatibility, the possibility of becoming responsible for substantial contingent or unanticipated legal liabilities as the result of corporate transactions, and changes in our geographic footprint and in the complexity of our operations. Moreover, effective internal controls are necessary to provide reliable and accurate financial reports, and the planned separation of our North America and EMEA businesses may create complexity in our financial systems and internal controls and make them more difficult to manage. Further regional integration of businesses into our internal control system could cause us to fail to meet our financial reporting obligations. Moreover, any failure to integrate the regional businesses, or delay in integrating the regional businesses, or IT systems of regional businesses could create an increased risk of cybersecurity incidents. Following our regional integration, efforts may not produce the expected margins or cash flows. Furthermore, we may finance these strategic transactions by incurring additional debt or issuing equity, which could increase leverage or impact our ability to access capital in the future. We are subject to cybersecurity and information technology risks related to breaches of security pertaining to sensitive company, customer, employee and vendor information as well as breaches in the technology used to manage operations and other business processes. Our business operations rely on securely managed information technology systems, some of which are provided or managed by third parties, for data capture, processing, storage and reporting. We have invested in information technology security initiatives and risk management, as well as incident response, business continuity and disaster recovery plans, but it is not possible to eliminate all systematic or external risk. Further, the development and maintenance of information technology security measures is costly and requires ongoing monitoring, testing and updating as technologies and processes change, and efforts to overcome security measures become increasingly sophisticated. Additionally, the global regulatory environment surrounding information security, data privacy and data protection is becoming increasingly restrictive and is evolving frequently. The current cyber threat environment presents increased risk for all companies, including those in our industry. Like other global companies, our systems are subject to recurring attempts by third parties to access information, manipulate data or disrupt operations. In this regard, we have experienced cyber threats and events from time to time, although none have materially affected us, including our results of operations or financial condition. Given the current cyber threat environment, the volume and intensity of cybersecurity attacks and attempted intrusions are expected to increase in the future. We work with a large and increasing number of third-party vendors, suppliers, platforms, software, applications, and technologies, each of which may be subject to a cybersecurity incident or information technology failure that impacts our business or operations. We may be required to spend significant resources to verify the implementation of cybersecurity controls by our vendors and suppliers. In addition, despite careful security and controls design, implementation, updating, monitoring and independent third-party verification, our information technology systems, together with those of our third-party providers or joint venture partners, have been and could again be compromised or disrupted due to factors such as employee error or malfeasance, cyber- attacks, including ransomware, malware, phishing attacks, advanced persistent threats, social engineering, credential stuffing or distributed denial-of-service attacks or data or security breaches by malicious actors such as common hackers, criminal groups or nation-state organizations or social activist (“hacktivist”) organizations, disruptions resulting from geopolitical events, natural disasters, failures or impairments of telecommunications networks or other catastrophic events. Such attacks are increasing in complexity, and the rapid evolution and increased adoption of AI technologies may intensify cybersecurity risks by making cyber-attacks more difficult to detect, contain, and mitigate. Furthermore, remote working and personal device use increases the risks of cyber incidents and the improper dissemination of personal or confidential information. Moreover, the hardware, software or applications we use may have inherent vulnerabilities or defects of design, manufacture or operations or could be inadvertently or intentionally implemented or used in a manner that could compromise information security. In addition, cybersecurity-related threats may remain undetected for an extended period of time. Table of Contents 23


 
Any cybersecurity attack, data or security breach, other security incident, compromise, damage, disruption, outage or shutdown to our or the information technology systems or networks, or those of any businesses with which we interact could result in lost sales, business delays, negative publicity or reputational impact, and a loss of customer confidence, and have a material adverse effect on our business or financial results. Any such incident or breach could also result in operational or supply chain disruptions, data loss, corruption or manipulation, or information misappropriation including, but not limited to, interruption to systems availability, denial of access to and misuse of applications required by customers to conduct business, the acquisition, use or disclosure of data or inability to access data, the release of confidential information about our operations, and subject us to litigation and government enforcement actions. Further, in such event, access to applications required to plan operations, source materials, manufacture and ship finished goods and account for orders could be denied or misused. Theft of intellectual property or trade secrets, and loss or inappropriate disclosure of confidential company, employee, customer or vendor information, could also stem from such incidents. Moreover, any significant cybersecurity event could require us to devote significant management time and resources in response to such event, interfere with the pursuit of other important business strategies and initiatives, and cause us to incur additional expenditures, which could be material, including to investigate and remediate such event, recover lost data, prevent future compromises and adapt systems and practices in response to such events. There is no assurance that any remedial actions will meaningfully limit the success of future attempts to breach our information systems, particularly because malicious actors are increasingly sophisticated and utilize tools and techniques specifically designed to circumvent security measures, avoid detection and obfuscate forensic evidence, which means we may be unable to identify, investigate or remediate effectively or in a timely manner. Further, we are subject to an increasing number of cybersecurity reporting obligations in different jurisdictions that vary in their scope and application, which may add complexities in providing complete and reliable information about cybersecurity incidents to customers, counterparties, and regulators, as well as the public. Corporate actions may impact our cybersecurity risk profile. As part of the strategic separation of our EMEA packaging business, we intend to assess and address these cybersecurity risks to ensure robust protection of our operations and data assets. Additionally, while insurance coverage designed to address certain aspects of cyber risks may be in place, such insurance coverage may be insufficient to cover all losses or all types of claims that may arise in connection with such incidents. Our continued growth will depend on our ability to retain existing customers and attract new customers. Our future growth will depend on our ability to retain existing customers, attract new customers as well as make existing customers and new customers increase their volume commitments. There can be no assurance that customers will continue to use our products or that they will be able to continue to attract new volumes at the same rate as in the past. A customer’s use of our products may decrease for a variety of reasons, including the customer’s level of satisfaction with our products and services, the expansion of business to offer new products, the effectiveness of our support services, the pricing of our products, the pricing, range and quality of competing products, the effects of global economic conditions, regulatory limitations, trust, perception and interest in the paper and packaging industry and in their products. Furthermore, customers can and do switch purchases between competing packaging providers. Any failure by us to retain existing customers, attract new customers, and increase revenue from both new and existing customers could have a material adverse effect on our business, results of operations, financial condition and/or future prospects. These efforts may require substantial financial expenditures, commitments of resources, developments of processes, and other investments and innovations without a guarantee that existing customers will be retained and/or new customers will be attracted. Uninsured losses or losses in excess of our insurance coverage for various risks could have an adverse financial effect on our business. We maintain business insurance that we consider to be adequate and appropriate for our business and activities. Certain types of risks such as losses due to natural disasters, riots, acts of war or terrorism are, however, either uninsurable or not economically insurable. In addition, even if a loss is insured, we may be required to pay a significant deductible on any claim for recovery of such loss prior to the insurer being obliged to reimburse the loss, or the amount of the loss may exceed the coverage for the loss. Any uninsured losses could have a material adverse effect on our business, financial condition, results of operations and/or future prospects. Table of Contents 24


 
We may not be able to adequately secure and protect our intellectual property rights, which could harm our competitive advantage. We rely on intellectual property laws to protect our rights to certain aspects of our systems, products and processes including product designs, proprietary technologies, research and concepts. For example, our packaging business owns hundreds of patents covering our designs and products. Trademarks and licenses and their effective management play an important role in protecting intellectual property rights. The actions taken by us to protect our respective proprietary rights may be inadequate to prevent imitation or unauthorized use. The laws of various countries offer different levels of protection for intellectual property rights and there can be no assurance that our intellectual property rights will not be challenged, invalidated, misappropriated or circumvented by third parties. Any of these possibilities could have a material adverse effect on our business, financial condition, results of operations and/or future prospects. We may fail to identify, prioritize or implement digital and/or AI transformation initiatives. We may fail to identify, prioritize or implement digital and/or AI transformation initiatives across our operations, including areas such as product design, materials sourcing, manufacturing, logistics, and customer delivery. Our failure to adopt or scale these capabilities in a timely manner could impair our ability to meet evolving customer expectations or may result in us falling behind our competitors with regards to innovation, speed to market, manufacturing efficiency, and service performance. Any such shortfall could have a material adverse effect on our business, financial condition, results of operations and/or future growth prospects. RISKS RELATED TO THE SEPARATION The proposed separation of our EMEA packaging business may not be completed, on the terms or the timeline announced, if at all, and we may fail to realize some or all of the potential benefits of the proposed separation. On January 29, 2026, we announced our intention to create two independent, publicly traded companies: International Paper will be comprised of its current business in North America including both legacy IP and DS Smith assets, and the EMEA packaging business will be comprised of both legacy DS Smith and IP assets in EMEA. The separation is expected to be structured as a spin-off of the combined EMEA Packaging business to shareholders and is expected to be completed within 12-15 months, subject to the satisfaction of certain customary conditions, including final approval by the IP Board of Directors as well as the filing and effectiveness of a registration statement with the U.S. Securities and Exchange Commission and the publication of a prospectus approved by the U.K. Financial Conduct Authority. Executing the proposed separation will require significant amounts of time and effort, which could divert management attention, disrupt the activities of our employees and have negative implications for our relationships with our customers and other third parties. We also expect to incur additional costs and expenses in connection with the separation. The proposed separation is complex, and completion of the proposed separation and the timing of its completion will be subject to a number of factors and conditions, including the readiness of the new company to operate as an independent public company, the successful integration of both legacy DS Smith and International Paper businesses in EMEA into one packaging business and finalization of the capital structure of the new company. The complexity and magnitude of the restructuring and regional integration efforts associated with the separation are significant and will continue to result in substantial costs. The restructuring and regional integration processes could cause an interruption of, or loss of momentum in, the other activities of the Company, and our failure to meet the challenges involved in successfully restructuring and regionally integrating legacy DS Smith and International Paper businesses in North America and EMEA, respectively, could adversely affect the ability to separate and our business financial condition, results of operations, and cash flows. Further, unanticipated developments could delay, prevent or otherwise adversely affect the proposed separation, including disruptions in general or financial market conditions, material adverse changes in business or industry conditions, unanticipated costs and potential problems or delays in obtaining various regulatory and tax approvals or clearances. There can be no assurances regarding the ultimate timing or structure of the proposed separation or that we will be able to complete the proposed separation on the terms or on the timeline that was announced, if at all. In the event that the separation is not completed, we will have incurred and may continue to incur, certain significant non-recurring costs related to the separation without realizing the anticipated benefits. Table of Contents 25


 
If the separation is completed, we may not be able to achieve the full strategic and financial benefits that are expected to result from the separation. An inability to realize some or all of the anticipated benefits of the separation, as well as any delays encountered in the process, could have an adverse effect on our business, financial condition, results of operations and cash flows. There can be no assurance that the combined value of the common stock and ordinary shares of the two companies will be equal or exceed the value that our common stock might have been had the proposed separation not occurred. RISKS RELATED TO OUR INDEBTEDNESS Changes in credit ratings issued by nationally recognized statistical rating organizations could adversely affect our cost of financing and have an adverse effect on the market price of our securities. Maintaining an investment-grade credit rating is an important element of our financial strategy. A downgrade of ratings below investment grade will likely eliminate our ability to access the commercial paper market, may limit access to the capital markets, have an adverse effect on the market price of our securities, increase borrowing costs and require us to post collateral for derivatives in a net liability position. The desire to maintain an investment grade rating may cause us to take certain actions designed to improve our respective cash flow, including the sale of assets, suspension or reduction of dividends and reductions in capital expenditures and working capital. Certain of our debt agreements provide for an interest rate increase in case of a credit rating downgrade. This applies to agreements governing approximately $4.0 billion of our debt as of December 31, 2025. As a result, a downgrade in credit rating may lead to an increase in interest expenses. There can be no assurance that our credit ratings will remain in effect for any given period of time or that such ratings will not be lowered, suspended or withdrawn entirely by the rating agencies if, in each rating agency’s judgment, circumstances so warrant. Any such downgrade, suspension or withdrawal of credit ratings could adversely affect our cost of borrowing, limit access to the capital markets or result in more restrictive covenants in agreements governing the terms of any future indebtedness that we may incur. The level of our indebtedness could adversely affect our financial condition and impair our ability to operate our business. As of December 31, 2025, we had approximately $9.8 billion of outstanding indebtedness. The level of our indebtedness could have important consequences to our financial condition, operating results and business, including the following: • it may limit our ability to obtain additional debt or equity financing for working capital, capital expenditures, product development, dividends, share repurchases, debt service requirements, acquisitions and general corporate or other purposes; • a portion of our cash flows from operations will be dedicated to payments on indebtedness and will not be available for other purposes, including operations, capital expenditures and future business opportunities; • the debt service requirements of our indebtedness could make it more difficult for us to satisfy other obligations; • it may limit our ability to adjust to changing market conditions, including taking actions in connection with changes in interest rates (such as in the current elevated interest rate environment), and place us at a competitive disadvantage compared to our competitors that have less debt; • it may increase our exposure to risks related to fluctuations in foreign currency as we earn profits in a variety of currencies around the world and our debt is denominated in U.S. dollars, British pounds and Euros; • it may increase our exposure to the risk of increased interest rates insofar as we are compelled to refinance indebtedness in an environment where rates, despite moderating in 2025, remain elevated and subject to ongoing volatility; and Table of Contents 26


 
• it may increase our vulnerability to a downturn in general economic conditions or in our business and may make us unable to carry out capital spending that is important to our growth. In addition, we are subject to agreements governing our indebtedness that require us to meet and maintain certain financial ratios and covenants. A significant or prolonged downturn in general business and economic conditions, or other significant adverse developments with respect to our results of operations or financial condition, may affect our ability to comply with these covenants or meet those financial ratios and tests and could require us to take action to reduce our debt or to act in a manner contrary to our current business objectives. Moreover, the restrictions associated with these financial ratios and covenants may prevent us from taking actions that we believe would be in the best interest of our business and may make it difficult for us to execute our business strategy successfully or effectively compete with companies that are not similarly restricted. Additionally, despite these restrictions, we may be able to incur substantial additional indebtedness in the future, which might subject us to additional restrictive covenants that could affect our financial and operational flexibility and otherwise increase the risks associated with our indebtedness as noted above. We are subject to risks associated with variable rate debt. We are subject to interest rate risk associated with short-term cash investments, variable rate debts, supply chain financing and short-term debt. We are also exposed to interest rate risk in relation to our installment notes and loans in the Temple Inland timber monetization special purpose entities. We have variable rate debt in the aggregate amount of approximately $2.1 billion as of December 31, 2025. Interest rates rose significantly during 2022-2024 but declined in 2025 following adjustments made by the Federal Reserve in response to economic conditions. Interest rates could remain volatile in 2026. Changes in interest rates impact the earnings on our short-term cash investments, the interest rate payable on our variable rate debt and credit agreements, the cost of supply chain financing and the refinance rate on our short-term debt. Downgrades in the credit ratings of banks issuing certain letters of credit will increase our cost of maintaining certain indebtedness and may result in the acceleration of deferred taxes. We are subject to the risk that a bank with currently issued irrevocable letters of credit supporting installment notes in connection with Temple Inland’s 2007 sales of forestlands, may be downgraded below the required rating. Prior to 2013, certain banks had fallen below the required ratings threshold and were successfully replaced, or waivers were obtained regarding their replacement. As a result of continuing uncertainty in the banking environment, the three letter-of-credit banks currently in place remain subject to risk of downgrade and the number of qualified replacement banks remains limited. The downgrade of one or more of these banks may subject us to additional costs of securing a replacement letter-of-credit bank or could result in an acceleration of deferred income taxes of $487 million if replacement banks cannot be obtained. RISKS RELATED TO LEGAL PROCEEDINGS AND COMPLIANCE COSTS Results of legal proceedings could have a material effect on our consolidated financial results. We are a party to various legal, regulatory and governmental proceedings and other related matters, including with respect to antitrust and environmental matters. In addition, we are and may become subject to other loss contingencies, both known and unknown, which may relate to past, present and future facts, events, circumstances and occurrences. Should an unfavorable outcome occur in connection with the legal, regulatory or governmental proceedings or our other loss contingencies or we become subject to any such loss contingencies in the future, there could be a material adverse impact on our financial results. See Note 14 - Commitments and Contingent Liabilities of Item 8. Financial Statements and Supplementary Data for further information. For example, we (through both International Paper and our DS Smith legacy subsidiaries operating in Italy) are among several of companies operating in the paper packaging industry subject to a decision by the Italian Competition Authority concerning anti-competitive behavior in Italy. We are further subject to a number of actual and threatened claims for compensation arising out of or relating to the decision by the Italian Competition Authority. In addition, International Paper has been named as a defendant in a purported class action complaint that alleges civil violation of Sections 1 and 3 of the Sherman Act. The complaint alleges that the defendants, beginning on November 1, 2020 through the present, conspired to fix, raise, maintain, and/or stabilize prices of containerboard products and seeks to recover treble damages, injunctive relief, attorneys’ fees and actual damages. Table of Contents 27


 
The Company is defending and intends to continue to defend robustly against such claims. It is too early to predict or reasonably estimate the overall outcome or ultimate potential liability (if any) that might be incurred in connection therewith, and there can be no guarantee that the aggregate of possible damages could not have a material impact on our financial condition. We could be exposed to liability for Brazilian taxes under our agreements with Sylvamo Corporation. In connection with the spin-off of Sylvamo Corporation (“Sylvamo”), we previously entered into agreements with Sylvamo and its subsidiaries, including among others a tax matters agreement. Under the tax matters agreement, we could have significant payment obligations in connection with certain Brazilian tax matters. Under this agreement, we have agreed to pay 60% of the first $300 million of any liability resulting from the resolution of these Brazilian tax matters (with Sylvamo paying the remaining 40% of the first $300 million of any such liability) and 100% of any liability resulting from the Brazilian tax matters over $300 million. These Brazilian tax matters relate to assessments for the tax years 2007-2015 of approximately $106 million in tax (adjusted for variation in currency exchange rates) and approximately $288 million in interest, penalties, and fees (adjusted for variation in currency exchange rates). Accordingly, the assessments total approximately $394 million (adjusted for variation in currency exchange rates), although interest, penalties and fees continue to accrue. Under the tax matters agreement, our potential liability for such assessments would currently be approximately $274 million (adjusted for variation in currency exchange rates). If we were found liable to pay such amounts, this could have an adverse effect on our business, financial condition, results of operations and/or cash flow. See Note 14 - Commitments and Contingent Liabilities of Item 8. Financial Statements and Supplementary Data for further information. DS Smith previously identified material weaknesses in its internal controls over financial reporting, including its Information Technology General Control environment, that, if not properly remediated, could increase the costs, expenses and management time required to meet the standards required by Section 404 of the Sarbanes-Oxley Act, and therefore adversely affect the business of the Company and its share price. A material weakness is a deficiency, or a combination of deficiencies, in internal control over financial reporting, such that there is a reasonable possibility that a material misstatement of our annual or interim consolidated financial statements will not be prevented or detected on a timely basis. Prior to January 31, 2025, DS Smith was not required to comply with Section 404 of the Sarbanes-Oxley Act or to formally assess the effectiveness of its internal controls over financial reporting for that purpose. As described under Item 8 “Report of Management on Financial Statements” and Item 9A. "Controls and Procedures," in connection with the preparation of the acquisition proxy statement, the independent auditors identified material weaknesses in DS Smith's internal control environment including Information Technology General Controls ("ITGCs") in fiscal years ended April 30, 2022, April 30, 2023, and April 30, 2024, which would have constituted material weaknesses under Section 404 of the Sarbanes-Oxley Act. DS Smith’s ITGCs were not consistently operating effectively due to inappropriate user and administrative access, ineffective change-management, inadequate third-party management, and insufficient authentication and security protocols. In accordance with SEC guidance, our management’s assessment of the effectiveness of the Company’s internal control over financial reporting as of December 31, 2025, excluded DS Smith. During 2025, International Paper worked to incorporate the internal controls and procedures for DS Smith into the Company’s internal control environment and will continue to incorporate the internal controls and procedures for the legacy DS Smith assets in North America post separation. Management is focused on remediating the DS Smith ITGC deficiencies, and has initiated a redesign of ITGCs across DS Smith systems, including enhancing governance over user access and system changes, by delivering training across DS Smith to further educate and upskill control and process owners. Management intends to implement the redesigned control framework in 2026. These remediation measures may be time consuming and costly and there is no assurance that these initiatives will ultimately have the intended effects. The deficiencies in DS Smith’s internal control over financial reporting will not be considered remediated until the controls operate for a sufficient period and management has concluded, through testing that these controls operate effectively. If we do not successfully remediate the deficiencies, or if other deficiencies are identified or arise in the future, we may incur additional costs and expenses and will be required to dedicate management's time to meeting the standards required by Section 404 of the Sarbanes-Oxley Act. In such case, we may be unable to maintain compliance with securities law requirements regarding timely filing of periodic reports, in addition to applicable stock exchange listing requirements and requirements under certain of our agreements, which could adversely affect investor confidence in us, our business, and the trading price of our Table of Contents 28


 
common stock. In addition, these DS Smith ITGC deficiencies may also have the effect of heightening other risks described in this “Risk Factors” section. RISKS RELATED TO CLIMATE AND WEATHER AND SOCIAL AND ENVIRONMENTAL IMPACT REPORTING We are subject to risks associated with climate change and other sustainability matters and global, regional and local weather conditions as well as by legal, regulatory, and market responses to climate change. Climate change impacts, including rising temperatures, extreme temperature events (such as prolonged heat or freezing conditions) and the increasing severity and/or frequency of adverse weather conditions, may result in operational impacts on our facilities, as well as supply chain disruptions and increased raw material and other costs. These adverse weather conditions and other physical impacts which may be exacerbated as the result of climate change include floods, hurricanes, tornadoes, earthquakes, hailstorms, wildfires, snow, ice storms and drought. Climate change may also contribute to the decreased productivity of forests, a key source in the production of paper products, and adverse impacts on the distribution and abundance of species, and the spread of disease and insect epidemics, any of which developments could adversely affect forestland management and the availability of energy and water resources. The effects of climate change and global, regional and local weather conditions, including the resulting financial costs of compliance with legal or regulatory initiatives, could have a material adverse effect on our results of operations and business. In recent years, there has been a heightened focus, including from investors, customers, the general public, domestic and foreign governmental (including but not limited to the United Kingdom and the European Union) and nongovernmental authorities, regarding sustainability matters, including with respect to climate change, greenhouse gas (“GHG”) emissions, packaging and waste, sustainable supply chain practices, biodiversity, deforestation, land, energy and water use, and human capital matters. This heightened focus on sustainability matters, including climate change, has resulted in more prescriptive reporting requirements with respect to sustainability metrics and other new requirements, an increased expectation that such metrics will be voluntarily disclosed by companies such as ours, and increased pressure with respect to making commitments, setting targets, or establishing goals, and taking action to meet them, which has caused and is expected to continue to cause the Company to incur increased compliance costs. As the result of this increased focus and commitment to sustainability matters, we (either voluntarily and/or as required by applicable law and regulation) have provided disclosure and established targets and goals with respect to various sustainability matters, including climate change. For example, we have publicly committed to reducing our Scope 1, 2 and 3 GHG emissions by 35% from 2019 to 2030. Meeting these and other sustainability targets and goals have increased our capital and operational costs. Further, we may continue to establish, increase and/or revise such disclosure, targets and goals in the future. For example, as we prepare to separate our EMEA operations, we intend to assess International Paper’s 2030 goals and adapt our existing targets and timelines. Efforts to achieve our initiatives and goals, including collecting, measuring, and reporting sustainability information, involve operational, reputational, financial, legal, and other challenges and may result in additional costs or delays related to achieving our 2030 goals. Such efforts may have a negative impact on us, including our brand name, reputation, and the market price of our common stock. There also continues to be a lack of consistency in implementation expectations of legal and regulatory initiatives regarding climate change across jurisdictions and various governmental entities. Additional expenses are expected to be incurred because of domestic and international regulators requiring additional disclosures regarding GHG emissions. Further, there can be no assurance regarding the extent to which our climate and other sustainability targets can be achieved, and the achievement of these targets is subject to various risks and uncertainties, some of which are outside our control. Moreover, there is no assurance that investments made in furtherance of achieving such targets and goals will meet investor expectations or any binding or non-binding legal standards regarding sustainability performance. If we are unable to meet climate and other sustainability targets and goals, on projected timelines or at all, or if such goals and targets are perceived negatively, including the perception that they are not sufficiently robust or, conversely, are too costly or not otherwise in our best interests, investor, customer and other stakeholder relationships could be damaged, which could adversely impact our reputation, business and results of operations. Moreover, not all our competitors establish climate or other sustainability targets and goals at comparable levels, which could result in competitors having lower supply chain or operating costs as well as reduced reputational risks associated with not meeting such goals. We may be unable to manage energy demand needs within our sustainability targets and certain of our respective acquisitions may bring new sustainability challenges. Such inability to manage sustainability demands and Table of Contents 29


 
challenges could have a significant impact on our business, financial condition, results of operations and/or future prospects. Other climate-related business risks that we face, include risks related to the transition to a lower-carbon economy, such as increased prices for fossil fuels; the introduction of a carbon tax; increased regulation of operations and products, and the resulting potential for increased litigation; and more stringent and/or complex environmental and other permitting requirements. To the extent that climate-related business risks materialize, particularly if we are unprepared for them, we may incur unexpected costs, and our business may be materially and adversely affected. Additionally, sustainability reporting is becoming more broadly expected by regulators, investors, shareholders, and other third parties. If we do not adapt to or comply with such investor, customer, or other stakeholder expectations, or if we are perceived to have not responded appropriately or quickly enough to growing sustainability related concerns for sustainability issues, regardless of whether there is a regulatory or legal requirement to do so, we may suffer reputational damage or be precluded from doing business with certain customers. Our business, financial condition, and/or the market price of our common stock could be materially and adversely affected. Further, our sustainability and goals may not be favored by certain stakeholders, whose priorities and expectations may not align or may be opposed to one another, which could result in public scrutiny or reputational damage, and could impact the attraction and retention of investors, customers, and employees. RISKS RELATED TO OUR PENSION AND HEALTHCARE COSTS Our pension and health care costs are subject to numerous factors which could cause these costs to change. We have defined benefit pension plans covering substantially all U.S. salaried employees hired prior to July 1, 2004, and substantially all hourly union and non-union employees regardless of hire date. We froze participation for U.S. salaried employees under these plans, including credited service and compensation on or after January 1, 2019; however, the pension freeze does not affect benefits accrued through December 31, 2018. We continue to provide retiree health care benefits to certain former U.S. employees, as well as financial assistance toward the cost of individual retiree medical coverage for certain former U.S. salaried employees. Prior to the acquisition, DS Smith and its predecessor entities maintained a number of separate defined benefit pension arrangements for different employee groups. These plans were closed or frozen at different times and, in some cases, were subsequently terminated or transitioned to multiemployer plans. For certain union represented groups, we continue to make required contributions or other payments tied to historical withdrawal liabilities or plan funding obligations. We also assumed a small legacy retiree life insurance benefit for a limited group of former employees, which will continue only for the remaining covered participants through 2027. DS Smith did not provide retiree health care benefits to its U.S. employees, and no new retiree health care obligations were created as part of the acquisition. Pension costs are dependent upon numerous factors resulting from actual plan experience and assumptions of future experience. Pension plan assets are primarily made up of equity and fixed income investments. Fluctuations in actual market returns on plan assets, changes in general interest rates and in the number of retirees may impact pension costs in future periods. Likewise, changes in assumptions regarding current discount rates and expected rates of return on plan assets could increase pension costs. However, the impact of market fluctuations has been reduced as a result of investments in our pension plan asset portfolio which hedge the impact of changes in interest rates on the plan’s funded status. Drivers for fluctuating health costs include unit cost changes, health care utilization by participants, and potential changes in legal requirements and government oversight. If any of these factors cause pension costs or health care benefits to increase in future periods, this could have an adverse effect on our business, financial condition, results of operations and/or cash flow. Our U.S. and UK funded pension plans are currently fully funded on a projected benefit obligation basis; however, the possibility exists that over time we may be required to make cash payments to the plans, reducing the cash available for our business. We record an asset or a liability associated with our pension plans equal to the surplus of the fair value of plan assets above the benefit obligation or the excess of the benefit obligation over the fair value of plan assets. As of December 31, 2025, we had an overfunded U.S. qualified pension with a surplus of $366 million and an overfunded UK qualified pension with a surplus of $112 million. When aggregated with U.S. nonqualified pension obligations, the benefit surplus recorded under the provisions of Accounting Standards Codification 715, “Compensation – Table of Contents 30


 
Retirement Benefits,” as of December 31, 2025 was $148 million. The amount and timing of future contributions, which could be material, will depend upon a number of factors, including the actual earnings, changes in values of plan assets and changes in interest rates. If benefit obligations under the qualified pensions exceed the value of plan assets by more than permitted under applicable statutory minimum funding requirements, then we may be required to make additional contributions. Such contributions may have an adverse effect on our operational results and cash flow. ITEM 1B. UNRESOLVED STAFF COMMENTS None. ITEM 1C. CYBERSECURITY RISK MANAGEMENT AND STRATEGY The Company’s cybersecurity risk management processes are integrated into our overall risk management system. The Company has a formalized enterprise risk management program overseen by the Board of Directors and committees of the Board of Directors that addresses strategic, operational, financial, compliance, legal and information technologies and cybersecurity risks. Each year, the Chief Audit Executive provides the Board of Directors and members of the ELT with a comprehensive update on the Company’s risk management activities. This update includes a structured, collaborative review through which key risks are examined and prioritized. In 2025, the Board of Directors identified seven priority risks for the Company, including cybersecurity. The Company has an Information Technology (“IT”) Risk Governance Program that aligns with our enterprise risk management framework and assists with fulfilling oversight responsibilities for major IT risks, including cybersecurity risks. An enterprise Cyber Governance, Risk, and Compliance function manages overall Company cyber risk, coordinating risk management functions with each business. Business and IT leaders conduct cyber risk reviews monthly within each business. These monthly reviews include the evaluation of new and evolving risks, management of risk mitigation plans, and a review of all cybersecurity incidents meeting certain criteria. Our Cybersecurity Risk Assessment Program The Company has a risk assessment program in place to assess, identify and manage material risks from cybersecurity threats. Cybersecurity risks the Company faces include targeted attacks, ransomware, malware, phishing attacks, data theft, other data or security breaches, virus and intrusion software, as well as attacks to our website, financial applications, operational technology, telecommunications and human resources data. Key aspects of the Company’s cybersecurity program include the following: • layered technical protective capabilities and detective surveillance controls; • using independent third parties to assess the Company’s practices related to, and provide expertise and assistance with, various aspects of information security, as further described below; • courses and awareness training on information security for employees with Company email or access to Company devices, including phishing, social engineering and other cybersecurity training as well as targeted training for specific roles based on responsibilities and risk level; • global security and privacy policies; and • business continuity, incident response and disaster recovery procedures, including table top exercises involving senior leaders. The Company does not believe that risks from cybersecurity threats, including as a result of any previous cybersecurity incidents, have materially affected the Company, including its business strategy, results of operations or financial condition. For a full discussion of cybersecurity risks facing the Company, please see Part I, Item 1A. Risk Factors - We are subject to cybersecurity and information technology risks related to breaches of security pertaining to sensitive company, customer, employee and vendor information as well as breaches in technology used to manage operations and other business processes. The Company carries cyber insurance which provides coverage in connection with cybersecurity breaches. Table of Contents 31


 
Engagement of Third Parties The Company engages third parties in connection with assessing, identifying and managing its cybersecurity risks. All of the following activities were conducted in both regions in 2025, except for the annual security program assessment which was completed in North America and is planned for EMEA in 2026: • Engagement of an independent third party with incident response expertise to provide intelligence-based cybersecurity solutions and services to assist the Company with preparing for, preventing, investigating, responding to and remediating cybersecurity incidents, including attacks that target on-premise, cloud, and critical infrastructure environments. • Engagement of an independent third party to conduct an annual security program assessment of the controls, maturity and performance of the Company’s information security program and the information security risk associated with the Company’s business systems. The assessment uses the National Institute of Standards and Technology Cybersecurity Framework as its benchmark. • Engagement of a leading third-party service provider to periodically perform an external and an internal penetration assessment using industry standard tools and techniques. In 2025, the Company began transitioning to a strategic outsourcing model for certain North America IT functions to enhance efficiency and resilience. The Company has employed the following processes to oversee and identify material risks from cybersecurity threats associated with the Company’s use of third-party service providers in North America and EMEA including the following: • The Company’s cybersecurity risk management program takes into account third-party systems whereby the Company could be impacted by the compromise of the security of vendors or other business relations of the Company, and the Company has a comprehensive third-party access management system. • The Company conducts risk-based due diligence on the profiles of third-party service providers with respect to cybersecurity risks prior to engagement. • Providers of critical and outsourced services are continuously monitored with respect to security risks, including periodic audits and compliance reviews. • The Company also requires service providers to adhere to the Company’s cybersecurity standards, maintain robust security controls, and provide prompt notification of any actual or suspected breach impacting Company data or operations. These measures are designed to mitigate risks associated with use of third parties including outsourcing of non- core IT functions overseas while maintaining compliance with applicable regulatory requirements and protecting the integrity of the Company’s systems and data. We expect the transition to be finalized in the second quarter of 2026. Additionally, our Internal Audit team conducts annual assessments of our cyber programs and controls. Oversight of Third Parties The Company has processes to oversee and identify material risks from cybersecurity threats associated with the Company’s use of third-party service providers. In this regard, the Company’s cybersecurity risk management program takes into account third-party systems whereby the Company could be impacted by the compromise of the security of vendors or other business relations of the Company, and the Company has a comprehensive third-party access management system. In addition, the Company conducts risk-based due diligence on the profiles of third- party service providers with respect to cybersecurity risks prior to engagement, and providers of critical and outsourced services are continuously monitored with respect to security risks, including periodic audits and compliance reviews. The Company also requires service providers to adhere to the Company’s cybersecurity standards, maintain robust security controls, and provide prompt notification of any actual or suspected breach impacting Company data or operations. These measures are designed to mitigate risks associated with use of third parties including outsourcing of non- core IT functions overseas while maintaining compliance with applicable regulatory requirements and protecting the integrity of the Company’s systems and data.

CYBERSECURITY GOVERNANCE Role of the Board of Directors and its Committees International Paper has an integrated board and executive-level governance structure that oversees risks from cybersecurity threats. The Company’s Board of Directors has primary oversight of our enterprise risk management program, which includes cybersecurity risk. Moreover, the Board of Directors is supported in its oversight by the Audit and Finance Committee and Public Policy and Environment Committee ("PPE Committee"), which share oversight responsibilities related to the Company’s information security programs. The Audit and Finance Committee reviews management’s cybersecurity and information security risk management programs and controls, including processes for management’s identification and reporting of material cybersecurity incidents. The PPE Committee reviews technology issues pertinent to the Company including those associated with information and operational technology, cybersecurity and data security and assesses related Company strategies. Our Board of Directors, Audit and Finance Committee and PPE Committee each receive periodic updates on cybersecurity issues from management (including our Chief Information Security Officer (“CISO”)). For example, the CISO provides reports to the Audit and Finance Committee and PPE Committee annually regarding cybersecurity risks, as well as plans and strategies to mitigate those risks. Role of Management At a management level, our cybersecurity risk management program is led by our CISO. Our current CISO has been with the Company for over 30 years, worked in Information Technology for over 25 years, and has led the Company’s security efforts since 2011. Appointed as the Company’s first CISO in 2019, 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 several industry recognized certifications, such as Certified Information Systems Security Professional, Certified Information Security Manager, and Certified Ethical Hacker, among others. The Company has adopted a global 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 captures our North America and EMEA operations and is designed to address non-operational and operational cybersecurity events. Evaluation and response to cybersecurity events is led by our Cybersecurity Incident Response Teams (“CIRTs”), under the direction of our CISO. The CIRTs are made up of subject matter experts representing information security, information technology, operational technology and legal. The CIRTs perform an impact assessment with respect to cybersecurity incidents, gathers facts and provides a chronology of events in connection therewith, and lead remediation and recovery activities. Our General Counsel, Senior Vice President, Chief Human Resources Officer, Chief Ethics and Compliance Officer (or their respective designees), Global Chief Privacy Officer 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 Teams (“Incident Command Teams”). The Incident Command Teams perform 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. If deemed material, the event will be timely reported on a Current Report on Form 8-K in accordance with applicable SEC rules. ITEM 2.

EXECUTIVE SUMMARY 2025 Financial Summary • Net sales of $23.63 billion • Loss from continuing operations of $(2.84) billion includes the following: ◦ $2.47 billion pre-tax non-cash goodwill impairment charge ◦ $958 million non-cash accelerated depreciation associated with asset rationalization decisions ◦ $626 million of restructuring charges • Adjusted EBITDA (non-GAAP) from continuing operations of $2.98 billion (1) • Cash provided by operating activities of $1.70 billion • Free cash flow (non-GAAP) of $(159) million (1) (1) See "Non-GAAP Financial Measures" for a list of our non-GAAP financial measures and reconciliations to the most directly comparable GAAP measures. Overview Throughout 2025, we continued to execute a multi-year transformation designed to simplify our portfolio, sharpen our regional focus and improve underlying earnings power. The Company undertook significant strategic and operational changes driven largely by our 80/20 performance system, the integration of DS Smith and the divestiture of our Global Cellulose Fibers ("GCF") business. The Company acquired DS Smith in early 2025 for an enterprise value of approximately $9.9 billion. The acquisition expanded our geographic reach across both the North America and EMEA regions, enabling advantaged cost positions, superior customer experiences and improved supply positions. Integration progressed rapidly during 2025, with teams applying the 80/20 performance system across both regions to streamline combined operations, optimize production footprints, and realize supply chain and commercial synergies. By year-end, we had executed approximately $710 million of full run-rate cost-out actions, including synergy benefits attributable to the DS Smith combination. In North America, we continued to leverage 80/20 to simplify our business operations and focus our resources to accelerate growth. In our packaging business, we exited non-strategic export and specialty markets and rationalized higher cost capacity to better align with profitable customer demand. We achieved approximately $510 million of run-rate cost savings in 2025 with the closures of several mills and plants, allowing us to increase investment in our remaining assets. We also entered into a definitive agreement to divest our GCF business, positioning the company as a pure play leading sustainable packaging solutions company. Parallel with our efforts in North America, the Company advanced its integration and transformation strategy in EMEA, where it launched the 80/20 performance system with approximately $200 million of run-rate cost-out actions and synergy benefits actioned in 2025. Early adoption from teams across the regions has supported a smooth rollout as the Company positions the EMEA business for its next phase of operational focus and regional alignment. In the first quarter of 2026, we completed the sale of our GCF business to American Industrial Partners for $1.5 billion. We intend to use proceeds from the transaction to support strategic reinvestment in our packaging business, reduce debt to improve our credit profile and preserve financial flexibility and maintenance of a strong investment- grade credit rating. On January 29, 2026, the Company announced plans to separate into two independent, publicly traded companies: International Paper will be comprised of its current business in North America including both legacy IP and DS Smith assets, and the EMEA packaging business will be comprised of both legacy DS Smith and IP assets in EMEA. The separation is expected to be structured as a spinoff of the EMEA business to shareholders, with International Paper retaining a meaningful ownership stake. The transaction is expected to be completed within 12 to 15 months, subject to customary approvals, including final approval by IP’s Board of Directors, filing and effectiveness of registration statement with the U.S. SEC and publication of prospectus approved by the U.K. Financial Conduct Authority. No assurance can be provided regarding the ultimate timing or structure of the proposed separation or its eventual completion. The Company expects that creating two regionally focused businesses will allow each to tailor strategies to their distinct markets, enhance management focus, and support long-term value creation. In 2026, the Company expects Table of Contents 37


 
to continue advancing its transformation strategy through the planned strategic separation, targeted investment agendas, and continued operational improvements across its regional platforms. This strategic action represents the next phase of our transformation and is designed to advance long-term value creation for customers and shareholders. Following the separation, International Paper plans to intensify its focus on its North American operations, with an emphasis on targeted capital allocation, investments in productivity and innovation, and disciplined strategic acquisitions. As previously disclosed, IP intends to retain a meaningful ownership stake in the EMEA packaging business, which is expected to be listed on both London Stock Exchange and the New York Stock Exchange. For additional information about the separation, including process steps and anticipated impacts, please see Note 22 Subsequent Events of Item 8. Financial Statements and Supplementary Data and Part I, Item 1A. Risk Factors - Risks Related to the Separation. Market Conditions Throughout 2025, the Company operated in challenging demand environments across both North America and EMEA. In North America, market demand was weaker than expected throughout most of the year as economic uncertainty from tariffs, slower housing starts, weaker consumer sentiment and lower industrial production negatively impacted box demand. Although industry growth was subdued throughout 2025, we grew above market in the second half of the year as we gained commercial momentum through our focused customer service and reliability efforts. In EMEA, overall demand remained relatively soft throughout 2025 as macroeconomic uncertainty and volatility persisted, influenced by trade uncertainty, geopolitical tensions in the Middle East and the Russia- Ukraine conflict.

Non-GAAP Financial Measures The non-GAAP financial measures presented in this Form 10-K as referenced below have limitations as analytical tools and should not be considered in isolation or as a substitute for an analysis of our results calculated in accordance with GAAP. In addition, because not all companies utilize identical calculations, the Company's presentation of non-GAAP measures in this Form 10-K may not be comparable to similarly titled measures disclosed by other companies, including companies in the same industry as the Company. Users are cautioned not to place undue reliance on any non-GAAP financial measures presented in this Form 10-K. Below are the Company’s key non-GAAP financial measures and their definitions: Adjusted operating earnings (loss) and adjusted operating earnings (loss) per share are defined as earnings (loss) from continuing operations (a GAAP measure) excluding net special items and non-operating pension expense (income). Earnings (loss) from continuing operations and diluted earnings (loss) from continuing operations per share are the most directly comparable GAAP measures. The Company calculates adjusted operating earnings (loss) by excluding the after-tax effect of non-operating pension expense (income) and net special items, as described in greater detail below, from earnings (loss) from continuing operations reported under GAAP. Adjusted operating earnings (loss) per share is calculated by dividing adjusted operating earnings (loss) by diluted average shares of common stock outstanding. Management uses these non-GAAP financial measures to focus on ongoing operations and believes that such non-GAAP financial 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 financial measures, along with the most directly comparable GAAP measures, provides for a more complete analysis of the Company's results of operations. Adjusted EBITDA from continuing operations is defined as earnings (loss) from continuing operations before income taxes and equity earnings (loss), interest expense, net, net special items, non-operating pension expense (income) and depreciation and amortization. Earnings (loss) from continuing operations before income taxes and equity earnings (loss) is the most directly comparable GAAP measure. Beginning in 2025, management is also using this measure to focus on on-going operations and believes this measure is useful to investors. This change reflects investor feedback and management's view that Adjusted EBITDA from continuing operations provides a meaningful measure of the operating performance of the Company and helps enable investors to perform meaningful comparisons of past and present consolidated operating results from continuing operations. Free cash flow is defined as cash provided by (used for) operations less capital expenditures, and the most directly comparable GAAP measure is cash provided by (used for) operations. Management utilizes this measure in connection with managing our business and believes that free cash flow is useful to investors as a liquidity measure because it measures the amount of cash generated that is available, after reinvesting in the business, to maintain a strong balance sheet, pay dividends, repurchase stock, service debt and make investments for future growth. It should not be inferred that the entire free cash flow amount is available for discretionary expenditures. Operational income tax provision and operational effective income tax rate are calculated by adjusting the earnings (loss) from continuing operations before income taxes and equity earnings (loss), income tax provision (benefit) and rate to exclude net special items and non-operating pension expense (income). The most directly comparable GAAP measures are the reported income tax provision and effective income tax rate, respectively. Management believes that this presentation provides useful information to investors by providing a meaningful comparison of the income tax rate between past and present periods. Table of Contents 39


 
Below are reconciliations of the non-GAAP financial measures noted above to their most directly comparable GAAP measures: 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 (loss) 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. See Effects of Special Items Expense (Income) for additional detail regarding the net special items expense (income) referenced in the tables below.

Additionally, we recycle approximately one million tons of OCC and mixed and white paper through our 15 U.S. recycling plants. Our corrugated packaging plants are supported by regional design centers, which offer total packaging solutions and supply chain initiatives. In EMEA, our operations include 14 containerboard mills, 148 corrugated packaging plants and 20 recycling plants. BUSINESS SEGMENT RESULTS The following tables present net sales and business segment operating profit (loss), which is the Company's measure of segment profitability and is defined as earnings (loss) before income taxes and equity earnings (losses), including the impact of less than wholly owned subsidiaries and excluding interest expense, net, corporate expenses, net, net special items and non-operating pension expense. Business segment operating profit (loss) is a measure reported to our management for purposes of making decisions about allocating resources to our business segments and assessing the performance of our business segments and is presented in our financial statement footnotes in accordance with ASC 280 - "Segment Reporting." For additional information regarding business segment operating profit (loss), including a description of the manner in which business segment operating profit (loss) is calculated, see Note 21 - Financial Information by Business Segment of Item 8. Financial Statements and Supplementary Data. Demand for our products is closely correlated with non-durable industrial goods production, as well as with demand for e-commerce, processed foods, poultry, meat and agricultural products. In addition to prices and volumes, major factors affecting profitability are raw material and energy costs, freight costs, mill outage costs, manufacturing efficiency and product mix. PS NA In millions 2025 2024 Sales $ 15,175 $ 14,293 Business Segment Operating Profit (Loss) $ 572 $ 891 PS NA 2025 results include sales of $611 million and business segment operating profit (loss) of $(346) million for the DS Smith business.

prices, partially offset by lower volumes reflecting the impact of our box go-to-market strategy and mill strategic actions. Cost of products sold decreased by $241 million and was impacted by lower volumes, lower planned maintenance downtime costs and lower input costs, partially offset by higher operating costs. Operating costs were higher primarily due to increased costs on materials and services and increased spending on maintenance and reliability, partially offset by lower economic downtime. Input costs were lower, driven by lower recovered fiber and wood costs, partially offset by higher energy and chemical costs. Selling and administrative expenses were $52 million lower due to lower incentive compensation expense. Distribution costs were $37 million lower driven by lower sales volumes. Depreciation and amortization expense was $564 million higher, driven by accelerated depreciation associated with our mill and other strategic actions. Looking ahead to the first quarter of 2026, compared with the fourth quarter of 2025, sales volumes for corrugated boxes are expected to be lower due to seasonality and the exit of non-strategic markets. Operating costs are expected to be flat. Planned maintenance outage costs are expected to be higher due to the timing of planned outages. Operating and input costs are expected to be relatively flat. PS EMEA In millions 2025 2024 Sales $ 8,451 $ 1,355 Business Segment Operating Profit (Loss) $ (236) $ 60 PS EMEA 2025 results include sales of $7.2 billion and business segment operating profit (loss) of $(321) million for the DS Smith business. For legacy IP PS EMEA, sales were lower in 2025 compared with 2024, reflecting lower volumes in a soft demand environment and an unfavorable product mix. Cost of products sold decreased $54 million and was impacted by lower volumes, lower operating costs and lower input costs, primarily for energy costs. Selling and administrative expenses were $12 million lower driven by incentive compensation expense. Distribution expense was $25 million lower driven by lower sales volumes. Entering the first quarter of 2026, compared with the fourth quarter of 2025, sales volumes are expected to be higher due to known customer wins. Average sales margins are expected to be higher, reflecting a favorable product mix. Operating costs are expected to be higher primarily driven by the timing of energy subsidies and increased volumes. Planned maintenance outage costs are expected to be lower due to the timing of planned outages. Input costs are expected to be higher primarily driven by elevated energy costs. LIQUIDITY AND CAPITAL RESOURCES OVERVIEW A major factor in International Paper’s liquidity and capital resource planning is generation of operating cash flow, which is highly sensitive to changes in the pricing and demand for our major products. While changes in key operating cash costs, such as raw material, energy, mill outage and distribution, have an effect on operating cash generation, we believe our focus on commercial and operational excellence, as well as our ability to tightly manage costs and working capital has improved our cash flow generation over an operating cycle. Use of cash during 2025 was primarily focused on working capital requirements, capital spending into the business for growth including mill and plant improvements, equipment and new greenfield investments and returning cash to shareholders through dividends. CASH PROVIDED BY OPERATING ACTIVITIES Cash provided by operations, including discontinued operations, totaled $1.7 billion in both 2025 and 2024. Cash used by working capital components (accounts receivable, contract assets and inventory less accounts payable and accrued liabilities, interest payable and other) totaled $834 million in 2025, compared with cash used by working capital components of $10 million in 2024. The change in cash provided by operations in 2025 compared to the 2024 period was primarily due to significant payments made in 2025 that impacted operating cash flow, including DS Smith transaction costs and severance payments, as well as incentive compensation and other benefit payments. Table of Contents 45


 
INVESTMENT ACTIVITIES Cash used for investment activities, including discontinued operations, totaled $1.0 billion in 2025 compared with $808 million in 2024. The increase in cash used for investment activities in 2025 compared to 2024 is mainly due to higher capital expenditures of $936 million, offset by an increase in proceeds from sale of fixed assets of $127 million, proceeds from divestitures, net of transaction costs of $141 million and net cash acquired from acquisitions of $414 million. Including discontinued operations, capital expenditures were $1.9 billion in 2025, or 64% of depreciation and amortization, compared with $921 million in 2024, or 71% of depreciation and amortization. Capital spending as a percentage of depreciation and amortization, including discontinued operations, was impacted by accelerated depreciation of $958 million and $233 million for the years ended December 31, 2025 and December 31, 2024, respectively, related to mill strategic actions and other 80/20 actions. The following table shows capital expenditures by business segment for the years ended December 31, 2025 and 2024: In millions 2025 2024 Packaging Solutions North America $ 1,115 $ 710 Packaging Solutions EMEA 573 53 Subtotal 1,688 763 Corporate and other (a) 169 158 Capital Expenditures $ 1,857 $ 921 (a) Includes capital expenditures related to Corporate and GCF. Acquisitions See Note 7 Acquisitions of Item 8. Financial Statements and Supplementary Data for a discussion of the Company's acquisitions. FINANCING ACTIVITIES Financing activities during 2025 included debt issuances of $409 million and reductions of $255 million for a net increase of $154 million. Financing activities during 2024 included debt issuances of $102 million and reductions of $141 million. There were no early debt extinguishments during the years ended December 31, 2025 and December 31, 2024. Other financing activities during 2025 included the net issuance of approximately 3.7 million shares of treasury stock, while repurchases of common stock and payments of restricted stock withholding taxes totaled $65 million. During 2025, no shares of common stock were repurchased under the Company's share repurchase program. Through December 31, 2025, the Company had repurchased 119.8 million shares at an average price of $46.23, for a total of approximately $5.5 billion, since the repurchase program began in September 2013. The Company paid cash dividends totaling $977 million during 2025. Other financing activities during 2024 included the net issuance of approximately 2.0 million shares of treasury stock. Repurchases of common stock and payments of restricted stock withholding taxes totaled $23 million. During 2024, no shares of common stock were repurchased under the Company's share repurchase program. Through December 31, 2024, the Company has repurchased 119.8 million shares at an average price of $46.23, for a total of approximately $5.5 billion, since the repurchase program began in September 2013. The Company paid cash dividends totaling $643 million during 2024. Interest Rate Swaps Our policy is to manage interest cost using a mixture of fixed-rate and variable-rate debt. To manage this risk, International Paper utilizes interest rate swaps to change the mix of fixed and variable rate debt. During 2020, International Paper terminated its interest rate swaps with a notional amount of $700 million and maturities ranging from 2024 to 2026 with an approximate fair value of $85 million. Subsequent to the termination of the interest rate swaps, the fair value basis adjustment is amortized to earnings as interest income over the same period as a debt Table of Contents 46


 
premium on the previously hedged debt. The Company had no outstanding interest rate swaps for the years ended December 31, 2025 and 2024. Variable Interest Entities Information concerning variable interest entities is set forth in Note 15 Variable Interest Entities of Item 8. Financial Statements and Supplementary Data. LIQUIDITY AND CAPITAL RESOURCES OUTLOOK FOR 2026 We intend to continue making choices for the use of cash that are consistent with our capital allocation framework to drive long-term value creation. These include maintaining a strong balance sheet and investment grade credit rating, and creating value with a continued focus on cost reduction and making organic investments to maintain our world-class system and strengthen our businesses. On January 23, 2026, the Company completed the previously announced sale of its GCF business to AIP for $1.5 billion, including the issuance of preferred stock with an aggregate initial liquidation preference of $190 million. The Company plans to use a portion of the proceeds from the sale of the GCF business to pay down existing debt. As of December 31, 2025, approximately $2.96 billion remain authorized for repurchase under our share repurchase program, which has no expiration date. We may repurchase shares under such authorization in open market transactions (including block trades), privately negotiated transactions or otherwise, subject to prevailing market conditions, our liquidity requirements, applicable securities laws requirements and other factors. In addition, we have paid regular quarterly cash dividends and expect to continue to pay regular quarterly cash dividends in the foreseeable future. Each quarterly dividend is subject to review and approval by our Board of Directors. Long-Term Debt The following summarizes certain material provisions of our long-term debt facilities and current obligations. The following description is only a summary, does not purport to be complete and is qualified in its entirety by reference to the documents governing such indebtedness. For additional information regarding the Company’s credit agreements, outstanding and assumed indebtedness, see Note 16 Debt and Lines of Credit of Item 8. Financial Statements and Supplementary Data. At December 31, 2025, International Paper’s U.S. dollar denominated credit facilities totaled $1.9 billion, comprised of a $1.4 billion contractually committed bank credit agreement and up to $500 million available under its receivables securitization program. Management believes these credit agreements provide sufficient liquidity to manage operating cash flow variability during the current economic cycle. The credit agreements generally provide for interest rates at a floating rate index plus a pre-determined margin tied to International Paper’s credit rating. At December 31, 2025, the Company had no borrowings outstanding under the $1.4 billion credit agreement or the $500 million receivables securitization program. The Company’s credit agreements contain no restrictive covenants other than the financial covenants as described in Note 16 - Debt and Lines of Credit of Item 8. Financial Statements and Supplementary Data, and the borrowings under the receivables securitization program being limited by eligible receivables. The Company was in compliance with all its debt covenants at December 31, 2025 and within the thresholds stipulated. The financial covenants do not restrict any borrowings under the credit agreements. Commercial Paper In addition to the $1.9 billion capacity under the Company's credit agreements, International Paper has a commercial paper program with a borrowing capacity of $1.0 billion supported by its $1.4 billion credit agreement. Under the terms of the Company's commercial paper 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, 2025 and December 31, 2024 under this program. Assumed Debt In 2025, International Paper assumed foreign denominated debt of DS Smith in various currencies. Table of Contents 47


 
Euro Medium Term Notes Our subsidiary DS Smith initiated consent solicitations with the holders of several series of its outstanding euro- and sterling denominated notes to approve certain amendments to the notes’ terms and related trust deeds (the “Euro Medium Term Notes”). The amendments were designed to align DS Smith’s reporting and covenant framework with that of International Paper following the acquisition, and to provide greater flexibility for the reorganization of DS Smith’s subsidiaries. As part of the solicitation process, International Paper agreed to provide guarantees of DS Smith’s obligations under each series of the Euro Medium Term Notes. These amendments and guarantees were implemented in March 2025 through supplemental trust deeds. All principal amounts of the affected Euro Medium Term Notes remain outstanding. Credit and Bank Facilities The Company amended and restated its £1.25 billion multi-currency credit facility agreement, its €200 million credit facility and €60 million committed bank facility. The amendments (i) replaced the Company's standalone financial reporting requirements with International Paper’s financial information; (ii) aligned the facility's financial covenant with those in International Paper’s existing credit facilities; and (iii) updated certain events of default and undertakings to reflect International Paper's financing framework and to provide additional flexibility for potential subsidiary reorganization within the International Paper group. The £1.25 billion multi-currency credit facility allows for British pound sterling, euro and U.S. dollar-denominated borrowings at floating rates plus a pre-determined margin, with borrowings generally denominated to match the Company's cashflows. At December 31, 2025, the Company had €975 million and £10 million (approximately $1.2 billion) borrowings outstanding under the credit facility. The Company’s credit facility agreement is not subject to any restrictive covenants other than that International Paper must comply with the same negative covenants as per its existing credit facilities. IP was in compliance with all its debt covenants at December 31, 2025, and was well below the thresholds stipulated under the covenants as defined in the credit facility agreement. Further the financial covenants do not restrict any borrowings under the £1.25 billion credit facility agreement. The €200 million credit facility agreement provides for interest rates at a fixed rate for each facility. At December 31, 2025, the Company had €163 million (approximately $191 million) borrowings outstanding under the credit facility agreement. The credit facility agreements do not impose restrictive covenants other than requiring International Paper to comply with the same negative covenants applicable to its existing credit facilities. IP was in compliance with all applicable covenants as of December 31, 2025, and remained well within the thresholds. The financial covenants do not restrict the Company’s ability to borrow under the credit facility agreement. The €60 million committed bank facility, maturing in 2026, allows for British pound sterling, euro and US dollar- denominated borrowings. At December 31, 2025, there were no borrowings outstanding under this agreement. The Company has a £50 million uncommitted bank facility. At December 31, 2025, the Company had €55 million (approximately $65 million) borrowings outstanding under this agreement. During the year ended December 31, 2025, the Company had debt reductions of $255 million in 2025, related primarily to $26 million of capital leases, $27 million of environmental development bonds ("EDB"), $95 million of industrial development bonds ("IDB") and $61 million of bonds. In addition, during the year ended December 31, 2025, the Company also had debt issuances of $165 million of industrial development bonds. The Company also borrowed $244 million under its foreign denominated credit facilities during 2025. Capital Expenditures We increased capital spending in 2025 as the Company accelerated several multi-year investments to support our 80/20 approach, enhance mill productivity, expand capacity in key growth markets, and modernize equipment to improve safety, reliability and energy efficiency. In North America, these 2025 authorizations include investment of $250 million to convert a machine at the Riverdale mill in Selma, Alabama to produce containerboard and construction of a new state-of-the-art sustainable packaging box plant in Waterloo, Iowa. Capital expenditures for 2026 are planned at approximately $1.95 billion to $2.05 billion, or about 98% to 103% of depreciation and amortization, reflecting continued execution of these strategic projects. The timing and scope of planned investments will depend on operational needs and the availability of operating cash flows, and certain projects may be deferred if cash generation or market conditions weaken. Table of Contents 48


 
International Paper expects to be able to meet projected capital expenditures, service existing debt, meet working capital and dividend requirements and make common stock and/or debt repurchases for the next 12 months and for the foreseeable future thereafter with current cash balances and cash from operations, supplemented as required by its existing credit facilities. The Company will continue to rely on debt and capital markets for the majority of any necessary long-term funding not provided by operating cash flows. Funding decisions will be guided by our capital structure planning objectives. The primary goals of the Company’s capital structure planning are to maximize financial flexibility and maintain appropriate levels of liquidity to meet our needs while managing balance sheet debt and interest expense. We have repurchased, and may continue to repurchase, our common stock (under our existing share repurchase program) and debt (including through open market purchases, privately negotiated transactions or otherwise) to the extent consistent with this capital structure planning, and subject to prevailing market conditions, our liquidity requirements, applicable securities laws requirements and other factors. The majority of International Paper’s debt is accessed through global public capital markets where we have a wide base of investors. Maintaining an investment grade credit rating is an important element of International Paper’s financing strategy. At December 31, 2025, the Company held long-term credit ratings of BBB (stable outlook) and Baa2 (stable outlook) by S&P and Moody’s, respectively. Contractual obligations for future payments under existing debt and lease commitments and purchase obligations at December 31, 2025, were as follows: In millions 2026 2027 2028 2029 2030 Thereafter Debt maturities (a) $ 992 $ 2,584 $ 739 $ 381 $ 807 $ 4,328 Operating lease obligations 245 190 124 72 46 100 Purchase obligations (b) 3,018 661 432 311 263 1,150 Total (c) $ 4,255 $ 3,435 $ 1,295 $ 764 $ 1,116 $ 5,578 (a) Includes financing lease obligations. (b) Includes fiber supply and other service and supply agreements. (c) The table above does not reflect: (i) approximately $344 million of unrecognized tax benefits due to the uncertainty regarding the timing and amount of payment; (ii) $37 million of Deemed Repatriation Transition Tax under the 2017 Tax Cuts and Jobs Act, which will be settled in 2026; and (iii) $487 million deferred tax liability related to the Temple-Inland timber monetization, which will be settled with the maturity of the notes in 2027. We consider the undistributed earnings of our foreign subsidiaries as of December 31, 2025, to be permanently reinvested and, accordingly, no U.S. income taxes have been provided thereon (see Note 13 Income Taxes of Item 8. Financial Statements and Supplementary Data). We do not anticipate the need to repatriate funds to the United States to satisfy domestic liquidity needs arising in the ordinary course of business, including liquidity needs associated with our domestic debt service requirements. Pension Obligations and Funding At December 31, 2025, the projected benefit obligation for the Company’s defined benefit plans determined under U.S. GAAP was approximately $144 million lower than the fair value of plan assets. Plans that are subject to minimum funding requirements had plan assets of $486 million higher than the projected benefit obligation. Under current IRS funding rules, the calculation of minimum funding requirements differs from the calculation of the present value of plan benefits (the "projected benefit obligation") for accounting purposes. Funding contributions depend on the funding methods selected by the Company. The selected methods allow for the smoothing of asset values and interest rates used to measure the funding obligations. The Company continually reassesses the amount and timing of any discretionary contributions and elected not to make any voluntary contributions in 2023, 2024 or 2025. At this time, we do not expect to have any required contributions to our plans in 2026, although the Company may elect to make future voluntary contributions. The timing and amount of future contributions, which could be material, will depend on a number of factors, including the actual earnings and changes in values of plan assets and changes in interest rates. CRITICAL ACCOUNTING POLICIES AND SIGNIFICANT ACCOUNTING ESTIMATES The preparation of financial statements in conformity with U.S. GAAP requires International Paper to establish accounting policies and to make estimates that affect both the amounts and timing of the recording of assets, Table of Contents 49


 
liabilities, revenues and expenses. Some of these estimates require subjective judgments about matters that are inherently uncertain. Accounting policies whose application has had or is reasonably likely to have a material impact on the reported results of operations and financial position of International Paper, and that can require a significant level of estimation or uncertainty by management that affect their application, include the accounting for impairment of long- lived assets and goodwill, pensions, income taxes and business combinations. Management has discussed the selection of critical accounting policies and the effect of significant estimates with the Audit and Finance Committee of the Company’s Board of Directors and with its independent registered public accounting firm. IMPAIRMENT OF LONG-LIVED ASSETS AND GOODWILL 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 the carrying value of the assets. 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. An impairment of a long-lived asset exists when the asset’s carrying amount exceeds its fair value. In conjunction with the previous announcement and subsequent sale of the Global Cellulose Fibers business to AIP for $1.5 billion, the Company evaluated the long-lived assets for impairment. As a result, the Company recorded a net pre-tax charge of $1.07 billion ($805 million after taxes) for the year ended December 31, 2025 due to the difference between the sales price less estimated selling costs and the carrying value. This non-cash charge is included in Discontinued Operations, net of taxes in the accompanying consolidated statements of operations. We perform an annual goodwill impairment as of October 1. Additionally, interim assessments of possible impairments of goodwill are also made when events or changes in circumstances indicate that the carrying value of the asset may not be recoverable through future operations. A goodwill impairment exists when the carrying amount of goodwill exceeds its fair value. ASU 2011-08, "Intangibles - Goodwill and Other," allows entities testing goodwill for impairment the option of performing a qualitative assessment before performing the quantitative goodwill impairment test. If a qualitative assessment is performed, an entity is not required to perform the quantitative goodwill impairment test unless the entity determines that, based on that qualitative assessment, it is more likely than not that its fair value is less than its carrying value. The January 31, 2025 acquisition of DS Smith added approximately $4.3 billion of goodwill, of which $3.4 billion was allocated to the PS EMEA reporting unit and $0.9 billion was related to the PS NA reporting unit. The Company completed its annual goodwill impairment testing for the PS NA and PS EMEA reporting units as of October 1, 2025. Based on this assessment, no impairment was identified for either reporting unit. Later in the fourth quarter of 2025, the Company, as part of its annual strategic review, identified a triggering event driven by its updated strategic plan impacted by macroeconomic and industry outlooks, as well as the Company’s evaluation of a potential separation into two independent, publicly traded companies. In response, the Company performed a quantitative goodwill impairment test for the PS NA and PS EMEA reporting units, comparing each reporting unit’s carrying value to its estimated fair value. Estimated fair values were determined using discounted future cash flows and market multiples, which use inputs that are classified within Level 2 and Level 3 of the fair value hierarchy. The discounted cash flow approach requires significant management judgments, including assumptions related to forecasts of future revenues, operating margins, and discount rates. The market-multiple approach under the guideline public company method similarly requires significant assumptions regarding adjusted EBITDA multiples. As of December 31, 2025, the quantitative impairment test concluded that the carrying amount of the PS EMEA reporting unit exceeded its estimated fair value. As a result, the Company recorded a goodwill impairment charge of approximately $2.47 billion, which is reflected in Impairment of goodwill in the accompanying consolidated statement of operations. After the impairment charge the carrying value of the PS EMEA reporting unit approximates fair value. The estimated fair value of the PS EMEA reporting unit is sensitive to the underlying assumptions and a Table of Contents 50


 
material change in any one, or combination of assumptions, could result in material future goodwill impairment. The carrying amount of the PS NA reporting unit did not exceed its estimated fair value, and no impairment was recorded for that reporting unit. PENSION BENEFIT OBLIGATIONS The calculation of the pension benefit obligation and corresponding expense amounts are determined annually, with involvement of International Paper’s consulting actuary, and are dependent upon various assumptions including the expected long-term rate of return on plan assets, discount rates, projected future compensation increases and mortality rates. The calculations of pension benefit obligations and expense require decisions about a number of key assumptions that can significantly affect liability and expense amounts, including the expected long-term rate of return on plan assets and the discount rate used to calculate plan liabilities. Benefit obligations and fair values of plan assets as of December 31, 2025, for International Paper’s pension plan were as follows: In millions Benefit Obligation Fair Value of Plan Assets U.S. qualified pension $ 8,116 $ 8,482 U.S. nonqualified pension 218 — Non-U.S. pension 1,116 1,112 The table below shows the discount rate used by International Paper to calculate U.S. pension obligations for the years shown: 2025 2024 2023 U.S. Discount rate 5.53 % 5.68 % 5.10 % Non-U.S. Discount rate 5.11%-5.16% 4.99 % 5.88 % International Paper determines the actuarial assumptions to calculate liability information as of December 31 each year or more frequently if required and pension expense for the following year. International Paper consults with our third-party actuary in determining these actuarial assumptions. 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. The discount rate assumption was determined based on a hypothetical settlement portfolio selected from a universe of high-quality corporate bonds. The expected long-term rate of return on U.S. pension plan assets used to determine net periodic cost for the year ended December 31, 2025 was 7.00%. Decreasing the expected long-term rate of return on U.S. plan assets by an additional 0.25% would increase 2026 pension expense by approximately $21 million, while a decrease of 0.25% in the discount rate would increase pension expense by approximately $13 million. Actual rates of return earned on U.S. pension plan assets for each of the last 10 years were: Year Return Year Return 2025 11.8 % 2020 24.7 % 2024 (0.1) % 2019 23.9 % 2023 7.3 % 2018 (3.0) % 2022 (22.0) % 2017 19.3 % 2021 7.7 % 2016 7.1 % 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 in pension expense prospectively over a period that Table of Contents 51


 
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 and losses in subsequent years. The increase in 2025 pension expense primarily reflects lower asset returns, higher interest cost due to a higher discount rate, and the impact of curtailment and settlement losses. Assuming that discount rates, expected long-term returns on plan assets and rates of future compensation increases remain the same as of December 31, 2025, projected future net periodic pension plan expense (income) would be as follows: In millions 2027 2026 Pension expense (income) U.S. plans $ (27) $ (14) Non-U.S. plans (6) (6) Net (income) expense $ (33) $ (20) The Company estimates that it will record net pension income of approximately $14 million for its U.S. defined benefit plans in 2026, compared to expense of $42 million in 2025. The market value of plan assets for International Paper’s U.S. qualified pension plan at December 31, 2025 totaled approximately $8.5 billion, consisting of approximately 64% hedging assets and 36% return seeking assets. The Company’s funding policy for its qualified 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 plan, tax deductibility, the cash flows generated by the Company, and other factors. The Company continually reassesses the amount and timing of any discretionary contributions and could elect to make voluntary contributions in the future. There were no required contributions to the U.S. qualified plan in 2025. The nonqualified defined benefit plans are funded to the extent of benefit payments, which totaled $49 million for the year ended December 31, 2025. INCOME TAXES 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 Company's uncertain tax positions were $384 million and $204 million at December 31, 2025 and 2024, respectively. 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. The Company's valuation allowance was $1.5 billion and $1.2 billion at December 31, 2025 and 2024, respectively. While International Paper believes that these judgments and estimates are appropriate and reasonable under the circumstances, actual resolution of these matters may differ from recorded estimated amounts.

BUSINESS COMBINATIONS We account for acquisitions under ASC 805, Business Combinations, which requires allocating the purchase price to the fair values of assets acquired and liabilities assumed as of the acquisition date. This process involves significant estimates and assumptions, particularly for property, plant and equipment and identifiable intangible assets such as customer relationships and lists, trade names, and technology. Key inputs include forecasted cash flows, discount rates, market data, and other valuation factors. These estimates are inherently judgmental and subject to change as additional information becomes available during the measurement period (up to 12 months after closing). On January 31, 2025, we completed the combination with DS Smith for $9.9 billion. The purchase price allocation resulted in goodwill for the excess of purchase price over the fair value of net assets acquired. The fair value assigned to the assets and liabilities acquired above were measured using Level 2 and Level 3 inputs. The estimated fair value of inventory was determined using the Comparative Sales and Replacement Cost methods. Fair value estimates related to the trade name and patents identified intangible assets were determined using the Relief from Royalty method. The fair value estimates related to customer relationships and lists identified intangible assets were determined using the Multi-Period Excess Earnings method. The plants, properties and equipment, specifically the machinery and equipment and buildings and improvements, were valued using either the indirect or direct methods of the Cost Approach, while the land was valued using the Sales Comparison Approach. We have finalized the fair values of property, plant and equipment, intangible assets, and certain tax-related items, with assistance from third-party valuation specialists. See Note 1 and Note 7 of Item 8. Financial Statements and Supplementary Data for additional details. LEGAL PROCEEDINGS Information concerning certain legal proceedings involving the Company is set forth in Item 8. Financial Statements and Supplementary Data, which is incorporated by reference herein. Except as set forth in Note 14 Commitments and Contingent Liabilities, the Company is not subject to any administrative or judicial proceeding arising under any federal, state or local provisions that have been enacted or adopted regulating the discharge of materials into the environment or primarily for the purpose of protecting the environment that is likely to result in monetary sanctions of $1 million or more. RECENT ACCOUNTING DEVELOPMENTS See Note 2 Recent Accounting Developments of Item 8. Financial Statements and Supplementary Data for a discussion of new accounting pronouncements. EFFECT OF INFLATION Inflationary increases in certain input costs, such as energy, wood fiber and chemical costs, can impact the Company’s operating results as can general inflationary conditions, including labor market conditions, economic activity, consumer behavior, and supply shortages and disruptions. During 2025, inflationary pressures stabilized and moderated over the year and did not have a significant impact on our operating results. The Company's operating results are more strongly influenced by economic supply and demand factors in specific markets due to the impact on sales prices and volumes and exchange rate fluctuations when compared to inflationary factors. FOREIGN CURRENCY EFFECTS International Paper has operations in a number of countries. Its operations in those countries also export to, and compete with imports from other regions. As such, currency movements can have a number of direct and indirect impacts on the Company’s financial statements. Direct impacts include the translation of international operations’ local currency financial statements into U.S. dollars and the remeasurement impact associated with non-functional currency financial assets and liabilities. Indirect impacts include the change in competitiveness of imports into, and exports out of, the United States (and the impact on local currency pricing of products that are traded internationally). In general, a weaker U.S. dollar and stronger local currency is beneficial to International Paper. The currencies that have the most impact are the euro and pound sterling. Table of Contents 53


 
MARKET RISK We use financial instruments, including fixed and variable rate debt, to finance operations, for capital spending programs and for general corporate purposes. Additionally, financial instruments, including various derivative contracts, are used to hedge exposures to interest rate, commodity and foreign currency risks. We do not use financial instruments for trading purposes. Information related to International Paper’s debt obligations is included in Note 16 Debt and Lines of Credit of Item 8. Financial Statements and Supplementary Data. The fair value of our debt and financial instruments varies due to changes in market interest and foreign currency rates and commodity prices since the inception of the related instruments. We assess this market risk utilizing a sensitivity analysis. The sensitivity analysis measures the potential loss in earnings, fair values and cash flows based on a hypothetical 10% change (increase and decrease) in interest and currency rates and commodity prices. INTEREST RATE RISK Our exposure to market risk for changes in interest rates relates primarily to short- and long-term debt obligations and investments in marketable securities. We invest in investment-grade securities issued by financial institutions and in AAA-rated money market mutual funds, while limiting our exposure to any one issuer or fund. Our investments in marketable securities at December 31, 2025 and 2024 are stated at cost, which approximates market due to their short-term nature. At December 31, 2025, our interest rate risk exposure related to these investments was not material. We issue fixed and floating rate debt in a proportion that management deems appropriate based on current and projected market conditions. Derivative instruments, such as interest rate swaps, may be used to execute this strategy. At December 31, 2025 and 2024, the fair value of the net liability of financial instruments with exposure to interest rate risk was approximately $7.1 billion and $4.0 billion, respectively. The potential increase in fair value resulting from a 10% adverse shift in quoted interest rates would have been approximately $895 million and $206 million at December 31, 2025 and 2024, respectively. COMMODITY PRICE RISK The objective of our commodity exposure management is to minimize volatility in earnings due to large fluctuations in the price of commodities. Commodity swap or forward purchase contracts may be used to manage risks associated with market fluctuations in energy prices. At December 31, 2025 and 2024, the net fair value of these contracts was $21 million liability and $3 million asset. The potential loss in fair value from a 10% adverse change in quoted commodity prices for these contracts would have been approximately $40 million and $2 million at December 31, 2025 and 2024, respectively. FOREIGN CURRENCY RISK International Paper transacts business in many currencies and is also subject to currency exchange rate risk through investments and businesses owned and operated in foreign countries. The currencies that have the most impact are the euro and pound sterling. Our objective in managing the associated foreign currency risks is to minimize the effect of adverse exchange rate fluctuations on our after-tax cash flows as well as financial statement impact. We address these risks on as needed basis by entering into cross-currency interest rate swaps, foreign exchange contracts, or foreign currency denominated debt designated as net investment hedges. At December 31, 2025 and 2024, the net fair value of foreign currency derivative instruments was immaterial. The potential loss in fair value for such financial instruments from a 10% adverse change in quoted foreign currency exchange rates was also immaterial. ITEM 7A.

ITEM 8. FINANCIAL STATEMENTS AND SUPPLEMENTARY DATA REPORT OF MANAGEMENT ON: Financial Statements The management of International Paper Company is responsible for the preparation of the consolidated financial statements in this Annual Report on Form 10-K. The consolidated financial statements have been prepared using accounting principles generally accepted in the United States of America considered appropriate in the circumstances to present fairly the Company’s consolidated financial position, results of operations and cash flows on a consistent basis. Management has also prepared the other information in this Annual Report on Form 10-K and is responsible for its accuracy and consistency with the consolidated financial statements. As can be expected in a complex and dynamic business environment, some financial statement amounts are based on estimates and judgments. Even though estimates and judgments are used, measures have been taken to provide reasonable assurance of the integrity and reliability of the financial information contained in this Annual Report on Form 10-K. We have formed a Disclosure Committee to oversee this process. The accompanying consolidated financial statements have been audited by the independent registered public accounting firm Deloitte & Touche LLP (PCAOB ID No. 34). During its audits, Deloitte & Touche LLP was given unrestricted access to all financial records and related data, including minutes of all meetings of shareholders and the Board of Directors and all committees of the Board of Directors. Management believes that all representations made to the independent auditors during their audits were valid and appropriate. Internal Control Over Financial Reporting The management of International Paper Company is also responsible for establishing and maintaining adequate internal control over financial reporting (as defined in Rules (13a-15(e) and 15d-15(e) under the Exchange Act). ICFR is the process designed by, or under the supervision of, our principal executive officer and principal financial officer, and effected by our Board of Directors, management and other personnel to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes. All internal control systems have inherent limitations, including the possibility of circumvention and overriding of controls, and therefore can provide only reasonable assurance of achieving the designed control objectives. The Company’s internal control system is supported by written policies and procedures, contains self-monitoring mechanisms, and is audited by our internal audit function. Appropriate actions are taken by management to correct deficiencies as they are identified. Our procedures for financial reporting include the active involvement of senior management, our Audit and Finance Committee and our staff of highly qualified financial and legal professionals. The Company has assessed the effectiveness of its internal control over financial reporting as of December 31, 2025. In making this assessment, it used the criteria described in “Internal Control – Integrated Framework (2013)” issued by the Committee of Sponsoring Organizations of the Treadway Commission ("COSO"). Based on this assessment, management believes that, as of December 31, 2025, the Company’s internal control over financial reporting was effective. In accordance with SEC guidance, management's assessment of the effectiveness of the Company’s internal control over financial reporting as of December 31, 2025 excluded DS Smith, which was acquired by the Company during the last fiscal year on January 31, 2025. DS Smith constituted approximately 43% of the Company’s total assets as of December 31, 2025 and approximately 33% of the Company’s total net sales for the year ended December 31, 2025, respectively. The Company’s independent registered public accounting firm, Deloitte & Touche LLP, has issued its report on the effectiveness of the Company’s internal control over financial reporting. Internal Control Environment And Board Of Directors Oversight Our internal control environment includes an enterprise-wide attitude of integrity and control consciousness that establishes a positive “tone at the top.” This is exemplified by our ethics program that includes long-standing Table of Contents 55


 
principles and policies on ethical business conduct that require employees to maintain the highest ethical and legal standards in the conduct of International Paper business, which have been distributed to all employees. The Company provides a toll-free telephone helpline whereby any employee may anonymously report suspected violations of law or International Paper’s policy; and maintains an office of ethics and business practice. The internal control system further includes careful selection and training of supervisory and management personnel, appropriate delegation of authority and division of responsibility, dissemination of accounting and business policies throughout International Paper, and an extensive program of internal audits with management follow-up. The Board of Directors, assisted by the Audit and Finance Committee, monitors the integrity of the Company’s financial statements and financial reporting procedures, the performance of the Company’s internal audit function and independent auditors, and other matters set forth in its charter. The Audit and Finance Committee, which consists of independent directors, meets regularly with representatives of management, and with the independent auditors and the Internal Auditor, with and without management representatives in attendance, to review their activities. The Audit and Finance Committee Charter takes into account the New York Stock Exchange rules relating to audit committees and the SEC rules and regulations promulgated as a result of the Sarbanes-Oxley Act of 2002. The Audit and Finance Committee has reviewed and discussed the consolidated financial statements for the year ended December 31, 2025, including critical accounting policies and significant management judgments, with management and the independent auditors. The Audit and Finance Committee’s report recommending the inclusion of such financial statements in this Annual Report on Form 10-K will be set forth in our Proxy Statement. ANDREW K.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM To the shareholders and the Board of Directors of International Paper Company: Opinion on the Financial Statements We have audited the accompanying consolidated balance sheets of International Paper Company and subsidiaries (the "Company") as of December 31, 2025 and 2024, the related consolidated statements of operations, comprehensive income (loss), changes in equity, and cash flows for each of the three years in the period ended December 31, 2025, and the related notes (collectively referred to as the "financial statements"). In our opinion, the financial statements present fairly, in all material respects, the financial position of the Company as of December 31, 2025 and 2024, and the results of its operations and its cash flows for each of the three years in the period ended December 31, 2025, in conformity with accounting principles generally accepted in the United States of America. We have also audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the Company's internal control over financial reporting as of December 31, 2025, based on criteria established in Internal Control — Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission and our report dated February 27, 2026, expressed an unqualified opinion on the Company's internal control over financial reporting. Basis for Opinion These financial statements are the responsibility of the Company's management. Our responsibility is to express an opinion on the Company's financial statements based on our audits. We are a public accounting firm registered with the PCAOB and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB. We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement, whether due to error or fraud. Our audits included performing procedures to assess the risks of material misstatement of the financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the financial statements. We believe that our audits provide a reasonable basis for our opinion. Critical Audit Matters The critical audit matters communicated below are matters arising from the current-period audit of the financial statements that were communicated or required to be communicated to the Audit and Finance Committee and that (1) relate to accounts or disclosures that are material to the financial statements and (2) involved our especially challenging, subjective, or complex judgments. The communication of critical audit matters does not alter in any way our opinion on the financial statements, taken as a whole, and we are not, by communicating the critical audit matters below, providing separate opinions on the critical audit matters or on the accounts or disclosures to which they relate. Retirement Plans — Fair value of other investments — Refer to Note 19 to the financial statements Critical Audit Matter Description As of December 31, 2025, the Company’s US Pension Plan held approximately $2.2 billion in investments whose reported value is determined based on net asset value (“NAV”). The strategic asset allocation policy prescribed by the Company’s US Pension Plan includes permissible investments in certain hedge funds, private equity funds, and real estate funds whose reported values are determined based on the estimated NAV of each investment. These NAVs are generally determined by the US Pension Plan’s third-party administrators or fund managers and are subject to review and oversight by management of the Company and its third-party investment advisors. Table of Contents 57


 
Given a lack of a readily determinable value of these investments and the subjective nature of the valuation methodologies and unobservable inputs used in these methodologies, auditing the NAV associated with these investments requires a high degree of auditor judgment and an increased extent of effort. How the Critical Audit Matter Was Addressed in the Audit Our audit procedures related to the determination of NAV associated with the Company’s US Pension Plan’s investments in hedge funds, private equity funds, and real estate funds included the following, among others: • We tested the effectiveness of controls over the Company’s determination and evaluation of NAV, including those related to the reliability of NAVs reported by third-party administrators and fund managers. • We inquired of management and the investment advisors regarding changes to the investment portfolio and investment strategies. • We obtained a confirmation from the third-party custodian as of December 31, 2025 of all individual investments held in trust for the US Pension Plan to confirm the existence of each individual asset held in trust. • For selected investment funds with a fiscal year end of December 31, we performed a retrospective review in which we compared the estimated fair value recorded by the Company in the December 31, 2024 financial statements, to the actual fair value of the fund (using the per-share NAV disclosed in the fund’s subsequently issued audited financial statements), to evaluate the appropriateness of management’s estimation process. • We rolled forward the valuation from selected funds’ most recently audited financial statements to December 31, 2025. This roll forward procedure included consideration of the Company’s transactions in the fund during the period, as well as an estimate of the funds’ returns based on an appropriate, independently obtained benchmark or index. We then compared our independent fund valuation estimate to the December 31, 2025, balance recorded by the Company. For certain selected funds, our roll forward procedures included alternative procedures, such as inspecting trust statements for observable transactions near year-end to compare to the estimated fair value. • For certain investments, we inquired of management to understand year-over-year changes in the fund manager’s estimate of NAV and compared the fund’s return on investment to other available qualitative and quantitative information. Goodwill – Packaging Solutions EMEA – Refer to Notes 1 and 12 to the financial statements Critical Audit Matter Description The Company’s evaluation of goodwill for impairment involves the comparison of the fair value of each reporting unit to its carrying value annually or whenever events or changes in circumstances indicate that an evaluation should be completed. The Company estimates the fair value of its reporting units using income and market approaches. The estimate of the fair value using the income approach requires management to make significant estimates and assumptions related to forecasts of future revenues and operating margins, and discount rates. The determination of the fair value using the market approach requires management to make significant assumptions related to earnings before interest, taxes, depreciation, and amortization ("EBITDA") multiples for guideline public companies. Changes to the assumptions and estimates may result in a significantly different estimate of the fair value of the reporting units, which could result in a different assessment of the recoverability of goodwill or the impairment amount of goodwill. During the fourth quarter of 2025, the Company identified a triggering event as part of its annual strategic review, driven by updated macroeconomic and industry outlooks, as well as the Company's evaluation of a potential separation into two independent, publicly traded companies. We identified the assessment of goodwill for impairment for Packaging Solutions EMEA (“PS EMEA”) during the fourth quarter as a critical audit matter because of the significant estimates and assumptions management made to estimate the fair value of the reporting unit, and Table of Contents 58


 
the sensitivity of the estimate to changes in the assumptions, specifically the forecasts of future revenues and operating margins, and the discount rate used in the income approach; and the selection of EBITDA multiples of guideline public companies in the market approach. This required a high degree of auditor judgment and an increased extent of effort, including the need to involve our fair value specialists, when performing audit procedures to evaluate the reasonableness of management’s estimates and assumptions. How the Critical Audit Matter Was Addressed in the Audit Our audit procedures related to forecasts of future revenues and operating margins, and the selection of the discount rate, and EBITDA multiples of guideline public companies for the PS EMEA reporting unit, included the following, among others: • We tested the effectiveness of controls over management's goodwill impairment evaluation, including those over the determination of the fair value of the PS EMEA reporting unit, such as controls related to management's forecasts of future revenues and operating margins and selection of the discount rate and EBITDA multiples of guideline public companies. • We evaluated the reasonableness of management’s forecasts of future revenues and operating margins of PS EMEA by comparing the forecasts to (1) forecasted information in industry reports, market data, and guideline public company information, (2) internal communications to management and the board of directors, and (3) external communications made by management to analysts and investors. • With the assistance of our fair value specialists, we evaluated the reasonableness of the selection of the discount rate and EBITDA multiples of guideline public companies, by: ▪ Testing the source information underlying the determination of the discount rate, testing the mathematical accuracy of the calculation, and developing a range of independent estimates and comparing those to the discount rate selected by management. ▪ Comparing the reporting unit's growth and profitability to the guideline public companies selected, testing the source information underlying the determination of the EBITDA multiples, developing a range of independent estimates and comparing those to the EBITDA multiples selected by management, and testing the mathematical accuracy of the calculation. Business Combinations – Acquisition of DS Smith – Valuation of Customer Relationships and Lists – Refer to Note 1 and Note 7 to the financial statements Critical Audit Matter Description The Company completed the acquisition of DS Smith for $9.9 billion on January 31, 2025. 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. The identifiable intangible assets acquired in connection with the acquisition of DS Smith included customer relationships and lists of $3.4 billion. Management estimated the fair value of the customer relationships and lists intangible asset using the multi-period excess earnings method, which is a specific discounted cash flow method. The fair value determination of the customer relationships and lists required management to make significant estimates and assumptions related to forecasts of future revenues and operating margins, and selection of the customer attrition rate and discount rate. We identified the customer relationships and lists intangible asset as a critical audit matter because there was a high degree of auditor judgment and extent of effort involved in applying audit procedures and evaluating the significant assumptions related to forecasts of future revenues and operating margins, and the selection of customer attrition rate and discount rate, including the need to involve our fair value specialists. Table of Contents 59


 
How the Critical Audit Matter Was Addressed in the Audit Our audit procedures related to the forecasts of future revenues and operating margins, and the selection of the customer attrition rate and discount rate for the customer relationships and lists intangible asset included the following, among others: • We tested the effectiveness of controls over the fair value of the customer relationships and lists intangible asset, including management's controls over the forecasts of future revenues and operating margins, and selection of the customer attrition rate and discount rate. • We evaluated the reasonableness of management’s forecasts of future revenues and operating margins by comparing the projections to forecasted information in industry reports and companies in its peer group. • With the assistance of our fair value specialists, we evaluated the reasonableness of the (1) mathematical accuracy of the valuation for customer relationships and lists intangible asset, and (2) the following significant valuation assumptions: ▪ Customer attrition rate by testing the source information underlying the determination of the rate and testing the mathematical accuracy of the calculations. ▪ Discount rate by developing a range of independent estimates and comparing those to the discount rate selected by management. /s/ Deloitte & Touche LLP Memphis, Tennessee February 27, 2026 We have served as the Company's auditor since 2002. REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM To the shareholders and the Board of Directors of International Paper Company: Opinion on Internal Control over Financial Reporting We have audited the internal control over financial reporting of International Paper Company and subsidiaries (the “Company”) as of December 31, 2025, based on criteria established in Internal Control — Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO). In our opinion, the Company maintained, in all material respects, effective internal control over financial reporting as of December 31, 2025, based on criteria established in Internal Control — Integrated Framework (2013) issued by COSO. We have also audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the consolidated financial statements as of and for the year ended December 31, 2025, of the Company and our report dated February 27, 2026, expressed an unqualified opinion on those financial statements. As described in the Report of Management on Internal Control over Financial Reporting, management excluded from its assessment the internal control over financial reporting at DS Smith, which was acquired on January 31, 2025, and whose financial statements constitute 43% of total assets and 33% of total net sales of the consolidated financial statement amounts as of and for the year ended December 31, 2025. Accordingly, our audit did not include the internal control over financial reporting at DS Smith. Basis for Opinion The Company’s management is responsible for maintaining effective internal control over financial reporting and for its assessment of the effectiveness of internal control over financial reporting, included in the accompanying Report Table of Contents 60


 
of Management on Internal Control over Financial Reporting. Our responsibility is to express an opinion on the Company’s internal control over financial reporting based on our audit. We are a public accounting firm registered with the PCAOB and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB. We conducted our audit in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether effective internal control over financial reporting was maintained in all material respects. Our audit included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, testing and evaluating the design and operating effectiveness of internal control based on the assessed risk, and performing such other procedures as we considered necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinion. Definition and Limitations of Internal Control over Financial Reporting A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company’s internal control over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company’s assets that could have a material effect on the financial statements. Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate. /s/ Deloitte & Touche LLP Memphis, Tennessee February 27, 2026 Table of Contents 61

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS 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 products with primary markets and manufacturing operations in North America and Europe and additional markets and manufacturing operations in Latin America and North Africa. 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. DS Smith As a result of the acquisition of DS Smith, the Chief Operating Decision Maker (CODM) began reviewing and managing the Company’s financial results and operations under a revised structure that reflects the scope of the Company’s continuing operations: Packaging Solutions North America (PS NA) and Packaging Solutions EMEA (PS EMEA). The PS EMEA segment includes the Company's legacy EMEA Industrial Packaging business and the EMEA DS Smith business. As such, amounts related to the Company's legacy EMEA Industrial Packaging business have been recast out of the Industrial Packaging segment into the new PS EMEA segment for all prior periods. The North America DS Smith business has been included in the PS NA segment. Amounts related to the Company's legacy North America Industrial Packaging business have been reported in the PS NA segment for all prior periods. See Note 7 for further details regarding the DS Smith acquisition and Note 21 for further details regarding business segments. Global Cellulose Fibers Discontinued Operations Following the announcement on August 21, 2025 of a definitive agreement to sell the Global Cellulose Fibers (GCF) business, the GCF business is no longer a reportable segment and all current and historical operating results of the GCF business are presented as Discontinued Operations, net of taxes, in the consolidated statements of operations. All current and historical assets and liabilities of the Global Cellulose Fibers business are classified as Assets held for sale and Long-Term Assets Held For Sale and Liabilities held for sale and Long-Term Liabilities Held For Sale in the accompanying consolidated balance sheets. See Note 8 for further details regarding the Global Cellulose Fibers business and discontinued operations. 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 statements 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 sheets. The Company recorded discontinued operations for the years ended December 31, 2025, 2024 and 2023 in connection with the sale of its Global Cellulose Fibers business and for the year ended December 31, 2023 in connection with the sale of its equity method investment in Ilim. See Note 8 and Note 11 for further details. Table of Contents 67


 
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 11. OTHER-THAN-TEMPORARY IMPAIRMENT The 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, customer attrition rates, estimated replacement costs and depreciation and obsolescence factors. Determining the fair value for specifically identified intangible assets such as customer relationships and lists and developed technology involves judgment. We may refine our estimates and make adjustments to the assets acquired and liabilities assumed over a measurement period, not to exceed one year. Upon the conclusion of the measurement period or the final determination of the values of assets acquired and liabilities assumed, whichever comes first, any subsequent adjustments are charged to the consolidated statements of 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 when a present obligation exists and the amount of the obligation can be reasonably estimated. 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. Table of Contents 68


 
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 9 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 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 9 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. See Note 10 for further details. PLANTS, PROPERTIES AND EQUIPMENT Plants, properties and equipment, net are stated at cost, less accumulated depreciation. Expenditures for betterments are capitalized, whereas normal repairs and maintenance are expensed as incurred. Depreciation for the majority of paper mills, as well as other plants and equipment, is calculated using the straight-line method and depreciation for certain paper mills is based on the units-of-production method. 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 9 for further details. Table of Contents 69


 
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 and market 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 margins and discount rates. The determination of fair value using market multiples requires management to make significant assumptions related to 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 statements 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 13 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 14 for further details. DERIVATIVES AND HEDGING The Company and its subsidiaries are exposed to certain risks relating to its ongoing financial arrangements. The Company uses derivative financial instruments, primarily commodity swaps and forward contracts, to manage currency and commodity risks associated with the Company’s underlying business activities and the financing of these activities. As a matter of policy, we do not use financial instruments for speculative purposes. ASC 815 requires entities to recognize all derivative instruments as either assets or liabilities in the statement of financial position at fair value. The accounting for changes in the fair value (i.e., gains or losses) of a derivative instrument depends on whether it has been designated and qualifies as part of a hedge accounting relationship and, further, on the type of hedge accounting relationship. The cash flows related to derivatives and hedges are classified in the same category as the underlying transaction. For those derivative or nonderivative instruments that are designated and qualify as hedging instruments under ASC 815, a company must designate the hedging instrument, based upon the exposure being hedged, as a fair value hedge, cash flow hedge, or a net investment hedge. Gains or losses on cash flow hedges are deferred as a component of AOCL and are reclassified into earnings at the time the hedged item affects earnings, presented in the same income statement line item as the underlying hedged item (i.e., in “cost of products sold” when the hedged transactions are commodity cash flows associated with energy purchases to facilitate operations). If it becomes probable that a forecasted transaction will not occur, previously deferred gains and losses related to those forecasted transactions would be recognized in earnings in the current period. Gains and losses on net investment hedges are recorded in the cumulative translation adjustment component of AOCL, offsetting the translation adjustment of the net investment being hedged. Any deferred gains or losses previously recorded in the cumulative translation adjustment component of AOCL will remain in AOCL until the hedged net investment is sold or substantially liquidated, at which time the cumulative deferred gains or losses are reclassified into earnings as a component of gain or loss on the sale of the hedged net investment. To qualify for hedge accounting, a specified level of hedge effectiveness between the hedging instrument and the item being hedged must be achieved at inception and maintained throughout the hedged period. We formally document our risk management objectives, our strategies for undertaking the hedge transactions, the nature of and relationships between the hedging instruments and hedged items, and the method for assessing hedge effectiveness. Additionally, for qualified hedges of forecasted transactions, we specifically identify the significant Table of Contents 71


 
characteristics and expected terms of the forecasted transactions. Our designated derivative contracts include commodity swap contracts and forward contracts. Commodity swap contracts effectively modify the Company’s exposure to changes in natural gas and electricity prices by allowing the Company to purchase energy on a fixed- rate basis. Forward contracts effectively modify the Company’s exposure to fluctuations in the cost of carbon credits by allowing the Company to purchase carbon credits on a fixed-rate basis. These agreements involve the receipt of floating-rate amounts in exchange for fixed-rate amounts over the life of the agreements. See Note 17 for further details. TRANSLATION OF FINANCIAL STATEMENTS Balance sheets of non-U.S. dollar functional currency entities 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.

REVENUE CONTRACT BALANCES A contract asset is created when the Company recognizes revenue on its customized products prior to having an unconditional right to payment from the customer, which generally does not occur until title and risk of loss passes to the customer. A contract liability is created when customers prepay for goods prior to the Company transferring those goods to the customer. The contract liability is reduced once control of the goods is transferred to the customer. The majority of our customer prepayments are received during the fourth quarter each year for goods that will be transferred to customers over the following twelve months. Contract liabilities of $18 million and $30 million are included in Other current liabilities in the accompanying consolidated balance sheet as of December 31, 2025 and 2024, respectively. The difference between the opening and closing balances of the Company's contract assets and contract liabilities primarily results from the difference between the price and quantity at comparable points in time for goods 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 goods. As a general rule, none of our businesses provide equipment installation or other ancillary services outside of producing and shipping packaging 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. Table of Contents 74


 
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 (loss) 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 (loss) 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 2025 2024 2023 Earnings (loss) from continuing operations $ (2,838) $ 725 $ 313 Weighted average common shares outstanding 505.7 347.2 346.9 Effect of dilutive securities (a) Restricted performance share plan — 7.0 2.2 Weighted average common shares outstanding – assuming dilution 505.7 354.2 349.1 Basic earnings (loss) per share from continuing operations $ (5.61) $ 2.09 $ 0.90 Diluted earnings (loss) per share from continuing operations $ (5.61) $ 2.05 $ 0.89 (a) 4.5 million of securities were anti-dilutive for 2025 and were not included in the table.

NOTE 7 ACQUISITIONS On January 31, 2025, the Company completed its acquisition of the entire issued and to be issued share capital of DS Smith, a leading provider of sustainable paper-based packaging solutions across Europe and North America. This acquisition combines two complementary businesses to create a global leader in sustainable packaging solutions with industry leading positions in two geographies, Europe and North America. The acquisition is expected to enhance the efficiency of the Company's core operations in North America with the integration of DS Smith’s complementary U.S. business and strengthen the Company's capabilities to advance its strategy to be a truly global sustainable packaging solutions leader. Upon closing, IP issued 0.1285 shares for each DS Smith share, resulting in the issuance of 178,126,631 new shares of IP common stock ("New Company Common Stock"). As a result of the share issuance, the holders of the New Company Common Stock own approximately 34.1% of the Company's outstanding share capital. Based on the issuance of 178,126,631 new shares and the closing price of 55.63 on the close of January 31, 2025, the total purchase consideration for the completed acquisition was approximately $9.9 billion. Acquisition-related costs were $96 million and $86 million for the years ended December 31, 2025 and December 31, 2024, respectively, and were recorded in Selling and administrative expenses and Taxes other than payroll and income taxes in the accompanying consolidated statements of operations. On February 4, 2025, the Company began trading the New Company Common Stock and continues to be listed on the New York Stock Exchange under the trading symbol "IP" and via a secondary listing on the London Stock Exchange under the trading symbol "IPC." The headquarters of the combined company is based in Memphis, Tennessee, and the EMEA headquarters has been established at DS Smith's existing main office in London. The Company is accounting for the acquisition under ASC 805, "Business Combinations" and the results of operations have been included in International Paper's financial statements beginning with the date of acquisition.

The following table summarizes the fair value assigned to assets and liabilities acquired as of January 31, 2025: In millions Preliminary Adjustments (a) Final Cash and temporary investments $ 448 $ — $ 448 Accounts and notes receivable 1,386 (85) 1,301 Contract assets — 236 236 Inventories 852 (226) 626 Other current assets 147 164 311 Plants, properties and equipment 6,429 278 6,707 Intangibles 4,327 (412) 3,915 Goodwill 4,048 287 4,335 Overfunded pension plan assets 79 — 79 Right of use assets 257 13 270 Deferred charges and other assets 56 28 84 Total assets acquired 18,029 283 18,312 Notes payable and current maturities of long- term debt 60 58 118 Accounts payable 1,654 6 1,660 Accrued payroll and benefits 240 (8) 232 Other current liabilities 608 175 783 Long-term debt 3,634 (63) 3,571 Deferred income taxes 1,520 (7) 1,513 Underfunded pension benefit obligation 78 (7) 71 Long-term lease obligations 177 22 199 Other liabilities 149 107 256 Total liabilities assumed 8,120 283 8,403 Net assets acquired $ 9,909 $ — $ 9,909 (a) Revisions to the preliminary purchase price allocation were made as the Company refined its initial estimates within the adjustment period. These adjustments were not driven by events or changes that occurred after the acquisition date. The fair value assigned to the assets and liabilities acquired above were measured using Level 2 and Level 3 inputs, which are further defined in Note 1. The estimated fair value of inventory was determined using the Comparative Sales and Replacement Cost methods. Fair value estimates related to the trade name and patents identified intangible assets were determined using the Relief from Royalty method. The fair value estimates related to customer relationships and lists identified intangible assets were determined using the Multi-Period Excess Earnings method. The plants, properties and equipment, specifically the machinery and equipment and buildings and improvements, were valued using either the indirect or direct methods of the Cost Approach, while the land was valued using the Sales Comparison Approach. The allocation of the consideration transferred to the assets acquired and liabilities assumed has been finalized. Goodwill is not deductible for local income tax purposes and is primarily related to the value of new customers through expansion opportunities not reflected in the fair value of the existing customers relationships and the value of the intellectual property beyond selected life for trade names. Since acquisition, Net sales of $7.9 billion and Net earnings (loss) of $(3.5) billion have been included in the Company's consolidated statement of operations for the year ended December 31, 2025.

Below are the consolidated results on an unaudited pro forma basis assuming the DS Smith acquisition had closed on January 1, 2024: Year Ended In millions 2025 (Unaudited) 2024 (Unaudited) Net Sales $ 24,369 $ 24,298 Net Earnings (Loss) (3,541) 198 The unaudited pro forma information for the twelve months ended December 31, 2025 includes additional amortization expense on identifiable intangible assets of $16 million and additional depreciation expense on identifiable fixed assets of $28 million and excludes the write-off of the estimated fair value of inventory of $30 million and the non-recurring integration costs associated with the acquisition of $113 million. The unaudited pro forma information for the twelve months ended December 31, 2024 includes additional amortization expense on identifiable intangible assets of $192 million, additional depreciation expense on identifiable fixed assets of $336 million, incremental expense of $30 million associated with the write-off of the estimated fair value of inventory and non-recurring integration costs associated with the acquisition of $113 million. The unaudited pro forma consolidated financial information was prepared for comparative purposes only and includes certain adjustments, as noted above. The adjustments are estimates based on currently available information and actual amounts may have differed materially from these estimates. They do not reflect the effect of costs or synergies that would have been expected to result from the integration of the acquisition. The pro forma information does not purport to represent International Paper's actual results of operations as if the transaction described above would have occurred as of January 1, 2024, nor is it necessarily an indicator of future results. In connection with the DS Smith acquisition, the European Commission issued its Phase I clearance of the business combination between International Paper and DS Smith on January 31, 2025, with the condition that International Paper commit to divest five European plants in Mortagne, Saint-Amand, and Cabourg (France), Ovar (Portugal) and Bilbao (Spain). On June 30, 2025, the Company completed the sale of these locations to Palm Group of Germany for €125 million (approximately $147 million at the June 30, 2025 exchange rate) in cash. In conjunction with the completed sale, the Company recorded a net gain of $46 million for the year ended December 31, 2025, which is included in Net (gains) losses on sales and impairments of businesses in the accompanying consolidated statement of operations. NOTE 8 - DIVESTITURE On January 23, 2026, the Company completed the previously announced sale of its Global Cellulose Fibers business to AIP for $1.5 billion, including the issuance of preferred stock with an aggregate initial liquidation preference of $190 million. The fair value of the preferred stock is estimated using an income approach, which is classified as Level 2 within the fair value hierarchy. The fair value is calculated as the probability-weighted present value over all future modelled payoffs. In conjunction with this previous announcement and subsequent sale, the Company recorded a net pre-tax charge of $1.07 billion ($805 million after taxes) for the year ended December 31, 2025 related to the impairment of the Table of Contents 79

ACCOUNTS PAYABLE Under a supplier finance program, International Paper agrees to pay the relevant banks the stated amount of confirmed invoices from its designated suppliers on the original maturity dates of the invoices. International Paper or the relevant banks may terminate the agreement on notice periods from 28 to 90 days. The supplier invoices that have been confirmed as valid under the program require payment in full on the due date with no terms exceeding 180 days. The accounts payable balance included $368 million and $90 million of supplier finance program liabilities as of December 31, 2025 and 2024, respectively. The following table presents supplier finance program obligations confirmed and paid for the years ended December 31, 2025 and 2024: In millions Confirmed obligations outstanding at December 31, 2023 $ 90 Invoiced confirmed during the year 421 Confirmed invoices paid during the year (421) Confirmed obligations outstanding at December 31, 2024 90 Assumed as part of DS Acquisition 274 Invoiced confirmed during the year 1,382 Confirmed invoices paid during the year (1,378) Confirmed obligations outstanding at December 31, 2025 $ 368 INTEREST Interest payments of $550 million, $437 million and $459 million were made during the years ended December 31, 2025, 2024 and 2023, respectively.

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. NOTE 10 LEASES International Paper leases various real estate, including certain operating facilities, warehouses, office space and land. The Company also leases material handling equipment, vehicles, and certain other equipment. The Company's leases have remaining lease terms of up to 28 years. Table of Contents 83

See Note 7 - Acquisitions for further details. (b) Reflects PS EMEA Impairment losses and PS NA write-offs of previously impaired goodwill of $237 million and accumulated impairment losses of $(237) million. The Company completed its annual goodwill impairment testing for the Packaging Solutions North America (PS NA) and Packaging Solutions EMEA (PS EMEA) reporting units as of October 1, 2025. Based on this assessment, no impairment was identified for either reporting unit. During the fourth quarter of 2025, the Company identified a triggering event as part of its annual strategic review, driven by updated macroeconomic and industry outlooks, as well as the Company’s evaluation of a potential separation into two independent, publicly traded companies. In response, the Company performed a quantitative goodwill impairment test for the PS NA and PS EMEA reporting units, comparing each reporting unit’s carrying value to its estimated fair value. Estimated fair values were determined using discounted future cash flows and market multiples, which use inputs that are classified within Level 2 and Level 3 of the fair value hierarchy. The discounted cash flow approach requires significant management judgments, including assumptions related to forecasts of future revenues, operating margins and discount rates. The market-multiple approach similarly requires significant assumptions regarding adjusted EBITDA multiples. The quantitative impairment test concluded that the carrying amount of the PS EMEA reporting unit exceeded its estimated fair value. As a result, the Company recorded a goodwill impairment charge of approximately $2.47 billion, which is reflected in Impairment of goodwill in the accompanying consolidated statement of operations. The carrying amount of the PS NA reporting unit did not exceed its estimated fair value, and no impairment was recorded for that reporting unit. Table of Contents 86

Table of Contents 90


 
(b) The net deferred income tax liability for the years ended December 31, 2025 and 2024 includes net deferred tax liability of $42 million and $44 million included in held for sale. Deferred income tax assets and liabilities are recorded in the accompanying consolidated balance sheets under the captions Deferred charges and other assets and Deferred income taxes, respectively. The $487 million of deferred tax liabilities for forestlands, related installment sales, and investment in subsidiary is attributable to a 2007 Temple- Inland installment sale of forestlands (see Note 15 - Variable Interest Entities). During 2025, the Company incurred a $2.47 billion impairment charge related to the PS EMEA business segment. The impairment charge results in a deferred tax asset related to the investment in its PS EMEA subsidiaries. The Company intends to realize a portion of this deferred tax asset in 2026 for which a capital loss will be recognized for U.S. federal and state income tax purposes. A valuation allowance is recognized on the deferred tax asset to the extent the capital loss exceeds anticipated future capital gains. This results in the recognition of a net tax benefit of $271 million. 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 $401 million. The Company intends to carry back a portion of the loss to prior years and has set up a receivable in the amount of $265 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 $136 million for the year ended December 31, 2025. 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, 2025, 2024 and 2023 is as follows: In millions 2025 2024 2023 Balance at January 1 $ (204) $ (173) $ (177) Assumed as part of DS Smith acquisition (133) — — (Additions) reductions for tax positions related to current year (26) (10) (13) (Additions) for tax positions related to prior years (26) (40) (11) Reductions for tax positions related to prior years 14 7 1 Settlements 4 4 17 Expiration of statutes of limitations 1 6 11 Currency translation adjustment (14) 2 (1) Balance at December 31 $ (384) $ (204) $ (173) If the Company were to prevail on the unrecognized tax benefits recorded, substantially all of the balances at December 31, 2025, 2024 and 2023 would benefit the effective tax rate. 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 $92 million and $50 million accrued for the payment of estimated interest and penalties associated with unrecognized tax benefits at December 31, 2025 and 2024, respectively. The Company is currently subject to audits in the United States and other taxing jurisdictions around the world. Generally, tax years 2012 through 2024 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. Table of Contents 91


 
On July 4, 2025, the United States enacted the One Big Beautiful Bill Act (“OBBBA”). The OBBBA made significant tax law changes, including the extension of certain provisions of the 2017 Tax Cuts and Jobs Act, modifications to the U.S. international tax framework and the reinstatement of favorable treatment for certain business-related deductions. The tax provisions of the OBBBA have staggered effective dates beginning in 2025 and extending through 2027. The OBBBA did not have a material impact on the Company’s income tax provision or effective tax rate for the year ended December 31, 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 undistributed earnings of non-U.S. subsidiaries as of December 31, 2025 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.

NOTE 14 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. Table of Contents 92


 
Assessments of lawsuits and claims and the estimates reflected herein, are subject to significant judgments about future events, rely heavily on estimates and assumptions, and are otherwise subject to significant known and unknown uncertainties. The matters underlying such estimates may change from time to time and actual losses may vary significantly from current estimates. Additionally, the estimated liability for loss contingencies does not include matters or losses that are not reasonably estimable and probable. Based on information currently known to International Paper, management believes that loss contingencies arising from pending matters, including the matters described herein, will not have a material adverse effect on the consolidated financial position or liquidity of the Company. However, in light of the inherent uncertainties involved in such matters, some of which are beyond the Company's control, and the large or indeterminate damages sought in some of these matters, a future adverse ruling, settlement, unfavorable development, or increase in accruals with respect to these matters could result in future charges that could be materially adverse to the Company's results of operations or cash flows in any particular reporting period. Environmental The Company has been named as a potentially responsible party ("PRP") in environmental remediation actions under various U.S. federal and state laws, including the Comprehensive Environmental Response, Compensation and Liability Act of 1980, as amended ("CERCLA"). Many involve cleanup of hazardous substances at large commercial landfills that received waste from multiple sources. Liability for CERCLA cleanups is typically allocated among the 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 consolidated balance sheets. Remediation costs are recorded in the consolidated financial statements when they become probable and reasonably estimable. Reserve amounts may decline as remediation spending occurs. International Paper’s estimated probable liability for these environmental matters, totaled approximately $270 million and $279 million in the aggregate as of December 31, 2025 and December 31, 2024, respectively. Cass Lake: One matter involves a closed wood-treatment facility located in Cass Lake, Minnesota . The Company is performing remedial action ("RA") and continues to cooperate with the U.S. Environmental Protection Agency (“EPA”) on the remaining remediation goals. The estimated liability for the Cass Lake superfund site was $47 million and $48 million as of December 31, 2025 and December 31, 2024, respectively. Kalamazoo River: The Company is a PRP for the Allied Paper, Inc./Portage Creek/Kalamazoo River Superfund Site in Michigan, related to polychlorinated biphenyls contamination linked in part to a paper mill formerly owned by St. Regis Paper Company ("St. Regis"), to which the Company is a successor. • Operable Unit 5, Area 1 (“OU5”): In 2016, the EPA issued a special notice letter and a unilateral administrative order ("UAO") directing PRPs to perform the remedy and seeking $37 million in reimbursement costs. The Company continues to comply with the UAO while preserving defenses. • Operable Unit 1 ("OU1"): The EPA issued a Record of Decision (“ROD”) in 2016 and initiated RA activities in 2021. The Company received a UAO in 2022 and began performing the RA in 2023. Reserves of $27 million were established in 2022, increased by $27 million in 2024, and increased by $7 million in 2025 to account for the reasonably estimable costs for the next phases of the RA. The total combined reserve for liabilities for OU5, Area 1 and OU1 was $20 million and $29 million as of December 31, 2025 and December 31, 2024, respectively. The Company, along with NCR Corporation and Weyerhauser, 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. The lawsuit seeks contribution under CERCLA for approximately $79 million in past cleanup costs and unspecified future remediation costs. Although a district court initially fixed the past cost amount at approximately $50 million (plus interest to be determined) with 15% of those past costs allocated to the Company, the Sixth Circuit Court of Appeals (the "Sixth Circuit") ultimately found the lawsuit was time-barred. GP attempted further appeals, but the U.S. Supreme Court declined review. GP later sought a ruling that all parties were jointly and severally liable for future Table of Contents 93


 
costs. The District Court agreed, but on appeal the Sixth Circuit vacated that decision as well. The U.S. Supreme Court denied GP’s petition for certiorari in October 2025, making the Sixth Circuit’s ruling final. 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 actively participate in activities at the site and share costs. The Company initially reserved $65 million for estimated remediation costs: (a) $10 million for the southern impoundment; and (b) $55 million for the northern impoundment. The reserve represented the Company's 50% share of our estimate of the low end of the range of probable remediation costs. Reserves increased from 2020-2025 as completion of engineering estimates and higher than expected southern impoundment waste volumes increased projected costs. The Company substantially completed the RA for the southern impoundment in 2024. With respect to the northern impoundment, design revisions in 2024 and 2025 resulted in an increase to the reserve of $27 million. The total estimated liability for the southern and northern impoundment was $97 million and $98 million as of December 31, 2025 and December 31, 2024, respectively. The current reserve primarily reflects the Company’s 50% share of our estimate of the low end of the range of probable costs for the northern impoundment. Additional losses in excess of our recorded liability are possible due to uncertainties in future cost, timing and the development of additional site technical data pertaining to geotechnical, hydrological and other environmental conditions. Versailles Pond: The Company is a responsible party for the investigation and remediation of Versailles Pond, a 57-acre dammed river impoundment in Sprague, Connecticut contaminated with polychlorinated biphenyls, mercury, and metals.. A preliminary remediation plan was developed in 2023 and a $30 million reserve established. Negotiations with state and federal governmental officials about scope and timing of the remediation are ongoing. The total estimated liability for Versailles Pond was $29 million and $30 million as of December 31, 2025 and December 31, 2024, respectively. Asbestos-Related Matters We have been named as a defendant in various asbestos-related personal injury litigation, in both U.S. state and federal court, primarily in relation to the prior operations of certain companies previously acquired by the Company. The Company's total recorded liability with respect to pending and future asbestos-related claims was $103 million and $100 million net of insurance recoveries as of December 31, 2025 and December 31, 2024, 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 On July 29, 2025, 12 containerboard producers, including International Paper, were named as defendants in a purported class action complaint that alleges a civil violation of Sections 1 and 3 of the Sherman Act. The suit is captioned Artuso Pastry Foods Corp v. Packaging Corp. of America (N.D. Ill.). The complaint alleges that the defendants, beginning in November 1, 2020 through the time of filing, conspired to fix, raise, maintain, and/or stabilize prices of containerboard products and finished packaging products made from containerboard. The alleged class is formed from persons who purchased containerboard products directly from one or more defendants for use or delivery in the United States during the period November 1, 2020 to the present. The complaint seeks to recover an unspecified amount of treble damages, injunctive relief, attorneys’ fees and actual damages on behalf of the purported class. Given the early stage of the claim and our intention to defend robustly against such claim, it is too early to predict or reasonably estimate the overall outcome or ultimate potential liability (if any) that might be incurred. There can be no guarantee that the aggregate of possible damages could not have a material impact on our financial condition. 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 Table of Contents 94


 
producers, including International Paper's Italian packaging subsidiary ("IP Italy") and 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. Following a series of appeals by IP Italy to the Italian Council of State, IP Italy's fine was reduced by €6 million (approximately $6 million). As of December 31, 2025, after giving effect to this development, the Company did not have any remaining liability related to IP Italy's fine. IP Italy has further appealed the most recent decision (in July 2024) 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 the 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 $106 million (adjusted for variation in currency exchange rates) in tax, plus interest, penalties and fees. The interest, penalties and fees currently total approximately $288 million (adjusted for variation in currency exchange rates). Accordingly, the assessments currently total approximately $394 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 $250 million of the total $394 million as of December 31, 2025. On December 18, 2024, the Brazilian Federal Revenue Service appealed this ruling. This tax litigation matter may take many years to resolve. Sylvamo Brazil and International Paper believe the transaction underlying these assessments was appropriately evaluated, and that Sylvamo Brazil's tax position should be sustained, based on Brazilian tax law. This matter pertains to a business that was conveyed to Sylvamo on October 1, 2021, as part of our spin-off transaction. Pursuant to the terms of the tax matters agreement entered into between the Company and Sylvamo, the Company will pay 60% and Sylvamo will pay 40%, on up to $300 million of any assessment related to this matter, and the Company will pay all amounts of the assessment over $300 million. Under the terms of the tax matters agreement, decisions concerning the conduct of the litigation related to this matter, including strategy, settlement, pursuit and abandonment, will be made by the Company. Sylvamo thus has no control over any decision related to this ongoing litigation. The Company intends to vigorously defend this historical tax position against the current assessments and any similar assessments that may be issued for tax years subsequent to 2015. The Brazilian government may enact a tax amnesty program that would allow Sylvamo Brazil to resolve this dispute for less than the assessed amount. As of October 1, 2021, in connection with the recording of the distribution of assets and liabilities resulting from the spin-off transaction, the Company established a liability representing the initial fair value of the contingent liability under the tax matters agreement. The contingent liability was determined in accordance with ASC 460 "Guarantees" based on the probability weighting of various possible outcomes. The initial fair value estimate and recorded liability as of December 31, 2021 was $48 million and remains this amount at December 31, 2025. This liability will not be increased in subsequent periods unless facts and circumstances change such that an amount greater than the initial recognized liability becomes probable and estimable.

NOTE 15 VARIABLE INTEREST ENTITIES 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, 2025, this deferred tax liability was $487 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, 2025 and 2024, the fair value of the notes receivable was $2.3 billion. As of both December 31, 2025 and 2024, 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 2025 2024 2023 Revenue (a) $ 129 $ 152 $ 146 Expense (b) 115 136 136 Cash receipts (c) 113 135 122 Cash payments (d) 110 130 123 (a) The revenue is included in Interest expense, net, in the accompanying consolidated statements of operations and includes approximately $19 million for the years ended December 31, 2025, 2024 and 2023, 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 statements of operations and includes approximately $7 million for the years ended December 31, 2025, 2024 and 2023, 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. NOTE 16 DEBT AND LINES OF CREDIT 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, 2025 and December 31, 2024 under this program. At December 31, 2025, the Company's credit facilities totaled $1.9 billion, excluding the DS Smith credit facilities discussed below. 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 include a $1.4 billion contractually committed bank facility with a maturity date of June 2028. The liquidity facilities also include up to $500 million of uncommitted financings based on eligible receivables balances under a receivable securitization program that expires in June 2026. As of December 31, 2025 and December 31, 2024, the Company had no borrowings outstanding under the program. Table of Contents 96

At December 31, 2025, contractual obligations for future payments of debt maturities (including finance lease liabilities disclosed in Note 10 - Leases and excluding the timber monetization structures disclosed in Note 15 - Variable Interest Entities) by calendar year were as follows over the next five years: 2026 – $992 million; 2027 – $2.6 billion; 2028 – $739 million; 2029 – $381 million; and 2030 – $807 million. The Company’s financial covenants require the maintenance of a minimum net worth, as defined in our debt agreements, of $9.0 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, 2025, we were in compliance with our debt covenants. NOTE 17 DERIVATIVES AND HEDGING ACTIVITIES As a multinational company, International Paper is exposed to market risks, such as changes in interest rates, currency exchange rates and commodity prices. International Paper periodically uses derivatives and other financial instruments to hedge exposures to interest rate, commodity and currency risks. International Paper does not hold or issue financial instruments for trading purposes. For hedges that meet the hedge accounting criteria at inception, International Paper formally designates and documents the instrument as a fair value hedge, a cash flow hedge or a net investment hedge of a specific underlying exposure. Commodity Risk Management The Company has entered into commodity swap and commodity forward contracts which have been designated as cash flow hedges of commodity price risk associated with forecasted purchases and sales of various commodities used in the Company’s operations. These commodity contracts are used to manage exposure to changes in natural gas, electricity, and carbon credit prices. Individual commodity contracts are entered into up to three years prior to the occurrence of the hedged transactions. Foreign Currency Risk Management The Company and its subsidiaries periodically use non-derivative, foreign currency denominated loans to hedge the Company’s foreign currency exposure related to the translation of its net investment in foreign subsidiaries. Certain of these loans are designated as net investment hedges. The component of the gains and losses on our net investment in these designated foreign operations, driven by changes in foreign exchange rates, are economically offset by remeasurements of our foreign-currency denominated debt. The notional amounts of financial instruments used in hedging transactions were as follows: In millions December 31, 2025 December 31, 2024 Electricity contracts (MWh) 1.9 0.3 Natural gas contracts (MWh) 12.1 — Carbon credit contracts (tons) 0.1 — External debt (EUR) € 3,293 € — Table of Contents 98

Transfers between levels, if any, are recognized at the end of the reporting period. International Paper’s derivatives are classified as Level 2 within the fair value hierarchy. Fair value hierarchies are further defined in Note 1. The following table provides a summary of the impact of our derivative instruments in the balance sheet: Assets Liabilities In millions December 31, 2025 December 31, 2024 December 31, 2025 December 31, 2024 Derivatives designated as hedging instruments Commodity contracts – cash flow $ 2 $ — $ 63 $ — Derivatives not designated as hedging instruments Commodity contracts 67 3 27 — Total derivatives $ 69 (a) $ 3 (b) $ 90 (c) $ — (a) Includes $47 million recorded in Other current assets and $22 million recorded in Deferred charges and other assets in the accompanying consolidated balance sheet.

(b) Includes $3 million recorded in Other current assets in the accompanying consolidated balance sheet. (c) Includes $73 million recorded in Other current liabilities and $17 million recorded in Other liabilities in the accompanying consolidated balance sheet. The above contracts are subject to enforceable master netting arrangements that provide rights of offset with each counterparty when amounts are payable on the same date in the same currency or in the case of certain specified defaults. Management has made an accounting policy election to not offset the fair value of recognized derivative assets and derivative liabilities in the balance sheet. The amounts owed to the counterparties and owed to the Company are considered immaterial with respect to each counterparty and in the aggregate with all counterparties. Credit-Risk-Related Contingent Features International Paper evaluates credit risk by monitoring its exposure with each counterparty to ensure that exposure stays within acceptable policy limits. Credit risk is also mitigated by contractual provisions with the majority of our banks. Certain of the contracts include a credit support annex that requires the posting of collateral by the counterparty or International Paper based on each party’s rating and level of exposure. Based on the Company’s current credit rating, the collateral threshold is generally $15 million. The commodity swap and commodity forward contracts entered into by the Company do not contain collateral posting requirements. If the lower of the Company’s credit rating by Moody’s or S&P were to drop below investment grade, the Company would be required to post collateral for all of its derivatives in a net liability position, although no derivatives would terminate. There were no derivative instruments containing credit-risk-related contingent features in a net liability position as of December 31, 2025. The Company was not required to post any collateral as of December 31, 2025. NOTE 18 CAPITAL STOCK The authorized capital stock at both December 31, 2025 and 2024, consisted of 990,850,000 shares of common stock, $1 par value; 400,000 shares of cumulative $4 preferred stock, without par value (stated value $100 per share); and 8,750,000 shares of serial preferred stock, $1 par value. The serial preferred stock is issuable in one or more series by the Board of Directors without further shareholder action.

In connection with our acquisition, International Paper acquired the existing DS Smith Group Pension Scheme (the "Group Scheme"), a U.K. funded defined benefit plan providing pension benefits and lump sum benefits to members and dependents. The Group Scheme closed to new entrants and future accruals as of April 30, 2011. International Paper also acquired various non-U.S. retirement benefit arrangements as part of the acquisition, some of which are considered to be defined benefit pension plans for accounting purposes. 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 $49 million, $23 million and $22 million in 2025, 2024 and 2023, respectively, and which are expected to be $20 million in 2026. 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 19. 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 2025 and 2024 and the plans’ funded status. Table of Contents 101

The non-current asset for the qualified plan is included in the accompanying consolidated balance sheets 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 decrease in the discount rate from 5.68% at December 31, 2024 to 5.53% at December 31, 2025. The following are the components of the amounts recognized in other comprehensive income ("OCI") related to U.S. and non-U.S. plans during the years ended 2025, 2024 and 2023: Table of Contents 102

The portion of the change in funded status for the non-U.S. plans was $1 million, $11 million and $2 million in 2025, 2024 and 2023, respectively. The accumulated benefit obligation at both December 31, 2025 and 2024 was $8.3 billion for our U.S. defined benefit plans and $1.1 billion and $46 million at December 31, 2025 and 2024, respectively, for our non-U.S. defined benefit plans.

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: Table of Contents 103

The increase in 2025 pension expense primarily reflects lower asset returns, higher interest cost due to a higher discount rate, and the impact of curtailment and settlement losses. 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, 2025 is also the discount rate used to determine net pension expense for the 2026 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: 2025 2024 2023 U.S. Plans Non- U.S. Plans U.S. Plans Non- U.S. Plans U.S. Plans Non- U.S. Plans Actuarial assumptions used to determine benefit obligations as of December 31: Discount rate (b) 5.53 % 5.11% - 5.16% 5.68 % 4.99 % 5.10 % 5.88 % Rate of compensation increase (c) 3.00 % 2.90% - 3.39% 3.00 % 3.37 % 3.00 % 3.40 % Actuarial assumptions used to determine net periodic pension cost for years ended December 31: Discount rate (a) 5.52% - 5.68% 4.99 % 5.10 % 5.88 % 5.40 % 5.31 % Expected long-term rate of return on plan assets 7.00 % 3.63 % 7.00 % 3.79 % 6.50 % 3.83 % Rate of compensation increase 3.00 % 3.31 % 3.00 % 3.40 % 3.00 % 3.36 % (a) Nonqualified benefit cost reflects 5.68% for the period January 1, 2025 to March 31, 2025 and 5.52% for the period April 1, 2025 to December 31, 2025. (b) The discount rate assumption reflects a rate of 5.11% applied to the non-U.S. Plans and the 5.16% applied to the Group Scheme. (c) The rate of compensation increase reflects a rate of 2.90% applied to the Group Scheme and the 3.39% applied to the non-U.S. Plans. 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. Table of Contents 104


 
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 2026, 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 5.53% and an assumed rate of compensation increase of 3.00%. The Company estimates that it will record net pension expense (income) of approximately $(14) million for its U.S. defined benefit plans in 2026, compared to expense of $42 million in 2025. To calculate pension expense for 2026, the Company will use an expected long-term rate of return on plan assets of 6.53% for the Group Scheme, a discount rate of 5.16% and an assumed rate of compensation increase of 2.90%. The Company estimates that it will record net pension income of approximately $(19) million for the Group Scheme benefit plans in 2026, compared to income of $(16) million in 2025. For non-U.S. pension plans, assumptions reflect economic assumptions applicable to each country. The following illustrates the effect on the U.S. plan pension expense for 2026 of a 25 basis point decrease in the above assumptions: In millions 2026 Expense (Income): Discount rate $ 13 Expected long-term rate of return on plan assets 21 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. The Group Scheme has appointed a Board of Trustees responsible for the oversight of the Scheme, preparing the Statement of Investment Principles, and preparing, maintaining and revising a Schedule of Contributions. The investment strategy of the Scheme is designed to protect the security of members' accrued rights, limit volatility in the contribution rate, and to manage risk in a controlled fashion to achieve incremental excess return. The Group Scheme has established a strategic objective and investment benchmark, along with a long-term de-risking framework. Pension plan assets acquired as part of the DS Smith acquisition outside of the Group Scheme are not material.

Publicly traded equities are valued at the closing prices reported in the active market in which the individual securities are traded. Table of Contents 107


 
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 flow 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, 2025 and 2024, respectively: Derivatives at December 31, 2025 In millions Gross Asset Gross Liability Total Collateral $ 8 $ (7) $ 1 Credit Default Swap 8 — 8 Interest Rate Swap 5 — 5 Bond/Equity Swap 8 — 8 Total $ 29 $ (7) $ 22 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 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 Company continually reassesses the amount and timing of any discretionary contributions. No voluntary contributions were made in 2025, 2024 or 2023. 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, 2025, projected future pension benefit payments, excluding any termination benefits, were as follows: In millions 2026 $ 648 2027 648 2028 645 2029 642 2030 639 2031-2035 3,107 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. The Company also sponsors the International Paper Company Deferred Compensation Savings Plan, which is an unfunded nonqualified defined contribution plan. This plan permits eligible employees to continue to make deferrals and receive company matching contributions (and Retirement Savings Account contributions) when their contributions to the International Paper Salaried Savings Plan are stopped due to limitations under U.S. tax law. Participant deferrals and Company contributions are not invested in a separate trust, but are paid directly from International Paper’s general assets at the time benefits become due and payable.

plans totaled approximately $178 million, $177 million and $160 million for the plan years ended in 2025, 2024 and 2023, respectively. POSTRETIREMENT BENEFITS International Paper provides certain retiree health care and life insurance benefits covering certain salaried and hourly employees. These benefits are not considered material to the financial statements of the Company. NOTE 20 INCENTIVE PLANS 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"). 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. 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. The LTICP is administered by the Committee. Additionally, non-employee members of our Board of Directors receive grants of restricted stock for RSUs, under the Company's Restricted Stock and Deferred Compensation Plan for Non-Employee Directors, a subplan of the 2024 LTICP. Performance Stock Units PSU awards are earned over a three-year period based on the achievement of pre-established performance goals. The 2023-2025 and 2024-2026 Awards are weighted at 50% Return on Invested Capital ("ROIC") and 50% relative Total Shareholder Return ("TSR") for all participants. The 2025-2027 Awards are weighted 100% relative 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. RSU’s granted to non-employee directors vest annually and are restricted through January 1 following the year in which the non-employee director terminates service as a non-employee director. RSUs awarded to non-employee directors settle in cash. Table of Contents 110


 
Restricted Stock Restricted stock granted to non-employee directors vests annually following the one-year period beginning on the date of the Annual Meeting of Shareowners and ending on the last business day immediately preceding the next Annual Meeting of Shareowners. Restricted stock awarded to non-employee directors settle in shares. 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, 2025 Expected volatility 27.09% - 37.11% Risk-free interest rate 3.65% - 4.79% The following summarizes LTIP activity for the three years ended December 31, 2025: Share/Units Weighted Average Grant Date Fair Value 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 Granted - LTIP PSU 1,077,442 66.41 Granted - LTIP RSU 928,481 54.16 Shares issued - LTIP PSU (1,603,095) 50.88 Shares issued - LTIP RSU (958,536) 36.02 Forfeited (949,441) 45.37 Outstanding at December 31, 2025 5,413,176 $ 43.18 Table of Contents 111


 
RECOGNITION AWARD PROGRAM The Recognition Award Program ("RA Program") is time-based and designed for recruitment, retention and special recognition purposes. It provides for awards of RSUs to key employees.

This amount will be recognized in expense over a weighted-average period of 1.5 years. NOTE 21 FINANCIAL INFORMATION BY BUSINESS SEGMENT AND GEOGRAPHIC AREA On January 23, 2026, the Company completed the previously announced sale of its Global Cellulose Fibers business to AIP. As a result of the sale, the Global Cellulose Fibers business is no longer a reportable segment and all current and historical operating results of the Global Cellulose Fibers business are presented as Discontinued Operations, net of taxes, in the consolidated statements of operations. All current and historical assets and liabilities of the Global Cellulose Fibers business are classified as Assets held for sale and Long-Term Assets Held For Sale and Liabilities held for sale and Long-Term Liabilities Held For Sale in the accompanying consolidated balance sheets. See Note 8 - Divestiture for further details regarding the Global Cellulose Fibers business and discontinued operations. As a result of the acquisition of DS Smith, the Chief Operating Decision Maker (CODM) began reviewing and managing the Company’s financial results and operations under a revised structure that reflects the scope of the Company’s continuing operations: Packaging Solutions North America (PS NA) and Packaging Solutions EMEA (PS EMEA). The PS EMEA segment includes the Company's legacy EMEA Industrial Packaging business and the EMEA DS Smith business. As such, amounts related to the Company's legacy EMEA Industrial Packaging business have been recast out of the Industrial Packaging segment into the new PS EMEA segment for all prior periods. The North America DS Smith business has been included in the PS NA segment. Amounts related to the Company's Table of Contents 112


 
legacy North America Industrial Packaging business have been reported in the PS NA segment for all prior periods. PS NA and PS EMEA are primarily focused on producing fiber-based packaging. We produce linerboard, medium, whitetop, recycled linerboard, recycled medium and saturating kraft of which a majority of our production is converted into corrugated packaging and other packaging. The revenue for our PS NA and PS EMEA segments are derived from selling these products to our customers. The CODM assesses performance for these segments and decides how to allocate resources based on business segment operating profit, which is defined as earnings (loss) before income taxes and equity earnings (losses), including the impact of less than wholly owned subsidiaries and excluding interest expense, net, corporate expenses, net, net special items and non-operating pension expense. 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. 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, 2025, 2024 and 2023.

NOTE 22 SUBSEQUENT EVENTS On January 29, 2026, the Company announced a plan to create two independent, publicly traded companies through the separation of its PS NA and PS EMEA businesses. The PS NA business will be comprised of the Company's current business in North America, including both legacy IP and DS Smith assets, and the PS EMEA business will be comprised of both legacy DS Smith and IP assets in EMEA.

ITEM 9. CHANGES IN AND DISAGREEMENTS WITH ACCOUNTANTS ON ACCOUNTING AND FINANCIAL DISCLOSURE None. ITEM 9A. CONTROLS AND PROCEDURES As of December 31, 2025, an evaluation was carried out under the supervision and with the participation of the Company’s management, including our principal executive officer and principal financial officer, of the effectiveness of our disclosure controls and procedures (as that term is defined in Rule 13a-15(f) and 15d-15(f) of the Exchange Act). Based upon this evaluation, our principal financial officer and principal executive officer have concluded that the Company’s disclosure controls and procedures were effective as of December 31, 2025. In accordance with SEC guidance, management's assessment of the effectiveness of the Company’s internal control over financial reporting as of December 31, 2025, excluded DS Smith, which was acquired by the Company on January 31, 2025. The total assets and total net sales of DS Smith excluded from management’s assessment of internal control over financial reporting constituted approximately 43% of the Company’s total assets as of December 31, 2025 and approximately 33% of the Company’s total net sales for the year ended December 31, 2025, respectively. CHANGES IN INTERNAL CONTROL OVER FINANCIAL REPORTING On January 31, 2025, the Company acquired DS Smith. The Company is currently in the process of incorporating the internal controls and procedures for DS Smith into the Company’s Internal Controls over Financial Reporting ("ICFR"). At the time of the acquisition, DS Smith was not subject to Securities and Exchange Commission (“SEC”) requirements under Section 404 of the Sarbanes Oxley Act. Through AICPA audits performed as part of the preparation of the acquisition proxy statement, the independent auditors identified material weaknesses in DS Smith’s ICFR environment including Information Technology General Controls (“ITGCs”) in fiscal years ending April 30, 2022, 2023, and 2024. As noted above, Company management did not include DS Smith in its assessment of internal control over financial reporting as of December 31, 2025. Management continues to evaluate the ITGC deficiencies within the acquired DS Smith IT landscape and the implications to our internal control environment. There were no material errors in the financial results or balances identified and there was no change in previously released financial results required as a result of any identified control deficiencies. Management has initiated a redesign of ITGCs across DS Smith systems, including enhancing governance over user access and system changes, by implementing additional controls where historically absent, and by delivering training across DS Smith to further educate and upskill control and process owners. Management intends to implement the redesigned control framework in 2026. Except as noted above, there have been no other changes in our ICFR during the quarter ended December 31, 2025, that have materially affected, or are reasonably likely to materially affect, our ICFR. See Item 8. Financial Statements and Supplementary Data of this Form 10-K for management's annual report on our internal control over financial reporting and the attestation report of our independent public accounting firm. ITEM 9B. OTHER INFORMATION (a) Not applicable. (b) During the quarter ended December 31, 2025, no director or Section 16 officer adopted or terminated any Rule 10b5-1 trading arrangements or non-Rule 10b5-1 trading arrangements, as defined in Item 408 of Regulation S-K.
