2024 was a transformative year for International Paper, and my first as the Company's CEO and Chairman of the Board of Directors. I want to thank Mark Sutton for his service to the Company of nearly 40 years and for his support through my transition. I also want to acknowledge the strong engagement with our shareowners throughout the last 12 months. Your feedback, perspective and support have been invaluable.

In terms of our 2024 achievements, there were many.

Together, we embarked on a journey to reshape our Company by embracing safety above all else, and a customer-centric strategy aimed at driving profitable growth and enhancing our position as the leader in sustainable packaging solutions. By adopting a

disciplined 80/20 performance system, we focused on what matters most: safety, reducing complexity, lowering costs, and aligning resources to delight our customers.

Grounded in our values of safety, ethics, and excellence, we restructured our corporate organization, optimized operations, and executed our box go-to-market strategy. We made targeted investments to enhance reliability and better serve our customers. Through our successful and transformative business combination with DS Smith, we expanded our capabilities and increased our presence with customers in North America and EMEA. At the same time we made these changes, we maintained a solid balance sheet and remained committed to our dividend policy, returning $643 million to our shareholders.

In addition to my transition, several other key leadership changes occurred in 2024.

We named three new non-employee directors to our Board. We also elevated Company leaders to new roles and recruited new leaders to join IP. These leadership changes will strengthen our strategy execution and support our deliberate and thorough succession planning.

Looking ahead, we will continue our transformational journey in 2025, both in North America and Europe. Earlier this year, we welcomed DS Smith to the International Paper family. We expect that the IP/DS Smith combination will create significant opportunities for driving innovation, enhancing service, and achieving efficiencies for an advantaged cost position.

Our 80/20 performance system will continue to drive our improvement. We have an ambitious pipeline of capital projects aimed at optimizing our box system, improving mill reliability, and driving market share growth. These initiatives will be complemented by accelerating synergies from the DS Smith acquisition. Additionally, we continue to explore strategic options for our Global Cellulose Fibers business.

Proxy Summary / 2024 Performance Highlights

2024 Performance Highlights

We successfully laid the foundation to complete the acquisition of DS Smith Limited (formerly DS Smith Plc).

We began implementing an 80/20 performance system designed to deliver profitable market share growth.

We executed on strategic actions to align our workforce, optimize organizational structure and reduce operating costs to deliver sustainable packaging solutions to our customers.

A Transformational Year

Strategic Acquisition, New Leadership and Refreshed Board Propel Company Forward

2024 was a transformational year for International Paper (the "Company"), a global leader in sustainable packaging solutions, reflecting a commitment to becoming a global leader in the sustainable packaging industry. We increased our presence and scale in the attractive Europe, Middle East and Africa ("EMEA") region and implemented leadership transitions and strategic organizational development and change.

Acquisition of DS Smith

On January 31, 2025, our Company, through its subsidiary International Paper UK Holdings Limited, completed the acquisition of DS Smith Plc ("DS Smith"). DS Smith, originally a public company in England and Wales, has now been re-registered as a private company called DS Smith Limited. This acquisition was finalized through a court-approved arrangement with DS Smith's shareowners under UK law.

For each DS Smith share, shareowners received 0.1285 of a new share of our International Paper common stock, resulting in the issuance of 178,126,631 new shares. International Paper and DS Smith shareowners approved the acquisition in special meetings in October 2024.

On February 4, 2025, DS Smith shares were removed from the London Stock Exchange (the "LSE"). At the same time, our new Company shares started trading on the New York Stock Exchange under the symbol "IP." Additionally, our Company's common stock, including the new shares, began trading on the LSE under the secondary listing symbol "IPC."

Dynamic Executive Leadership and Vision

As we laid the foundation for completion of our DS Smith acquisition, the Company also underwent significant leadership changes under the direction of Andrew K. Silvernail, our new chief executive officer ("CEO") and chairman of the Board. Since assuming the role of CEO on May 1, 2024, Mr. Silvernail has strategically created an Executive Leadership Team (the "ELT"), consisting of leaders who report directly to him, to support and accelerate a customer-centric strategy to drive the Company toward its future goals and enhance operational efficiency.

Changes within the ELT include:

September 1, 2024

The Company promoted

W. Thomas Hamic to the newly created role of executive vice president and president-North American Packaging Solutions. Mr. Hamic leads our North American Packaging business in this newly created role.

January 31, 2025

Upon closing of the DS Smith acquisition, we named Timothy S. Nicholls as interim leader of our EMEA business.

Mr. Nicholls was promoted to executive vice president and president, DS Smith effective April 1, 2025. After serving as the Company's chief financial officer for seven years,

Mr. Nicholls now oversees our operations in the EMEA region, driving growth and strengthening our market presence.

February 3, 2025

We welcomed Joy N. Roman as our new senior vice president, chief people and strategy officer. Ms. Roman brings a wealth of experience in human resources and strategic planning, and is poised to foster a culture of innovation and talent development.

February 25, 2025

We appointed Lance T. Loeffler as the Company's new chief financial officer effective April 1, 2025. Mr. Loeffler brings a strong background in financial management and corporate finance, ensuring robust financial health and strategic investments.

These appointments reflect our commitment to building a dynamic and forward-thinking leadership team dedicated to achieving our strategic objectives and delivering long-term value to our shareowners. For more information on

Mr. Nicholls's promotion and Mr. Loeffler's appointment, please see our Current Report on Form 8-K filed with the U.S. Securities and Exchange Commission on February 28, 2025.

International Paper 2025 Proxy Statement

Refreshed Board

Our Board of Directors (the "Board") experienced major changes, adding three new members. These appointments are part of our ongoing commitment to strengthening our governance and enhancing the expertise within our Board. Our newest directors-Jamie A. Beggs, David A. Robbie and Scott A. Tozier-are audit committee financial experts with extensive experience as chief financial officers of large public companies. Mr. Robbie joined our Board in February 2025 from DS Smith and brings extensive knowledge and background of EMEA and has served on boards of companies listed on the London Stock Exchange. Ms. Beggs and Mr. Tozier joined the Board in May 2024 and were recommended to the Board by a third-party search firm.

These new directors reflect our dedication to maintaining a highly qualified board, capable of guiding International Paper toward sustained growth and success.

80/20 Performance System

Under the leadership of Mr. Silvernail, we adopted International Paper's 80/20 performance system in 2024 based on the principle that 80% of results come from 20% of efforts. The Company is implementing comprehensive training programs focused on 80/20 principles. These sessions equip our leaders with tools to drive improvement by simplifying, segmenting, resourcing and targeting growth. Additionally, the 80/20 performance system has been socialized with our Board through regular briefings that update them on Company progress and ensure alignment with our broader strategic objectives. The Board supports the adoption of the 80/20 mindset and is committed to championing its implementation throughout the Company.

Our 80/20 performance system helps guide investments and align resources to win with our most strategic customers, while reducing complexity and cost across the Company. Through 80/20, we intend to deliver profitable market share growth by striving to achieve an advantaged cost position and providing the most reliable and innovative sustainable packaging solutions to our customers across North America and EMEA.

Business Optimization

In 2024, as part of our 80/20 performance system, we took several key actions. We launched a corporate overhead restructuring plan to better align our workforce with business and customer needs, streamline our organizational structure and cut operational costs. Additionally, we announced the closure of certain facilities to focus on strengthening our most competitive and strategic assets and made targeted investments to improve reliability and better serve our customers. In October 2024, we also revealed our plans to explore strategic options for our Global Cellulose Fibers business.

Values

While we are focused on driving change and executing on our business transformation, we continue to be guided by the same values and fundamental principles that have shaped our Company for more than 125 years.
