International Paper Co.
International Paper Company (IP)
Overview
International Paper Company is an American packaging and paper company headquartered in Memphis, Tennessee, incorporated in 1898 through the merger of 17 pulp and paper mills across the northeastern United States and eastern Canada. It sits in the Packaging & Containers industry, and following its January 2025 acquisition of British packaging company DS Smith for roughly $7.2 billion, it has become one of the largest fiber-based packaging companies in the world, with revenue of about $23.6 billion in fiscal 2025 (roughly $24.2 billion on a trailing-twelve-month basis through mid-2026) and approximately 62,600 employees — nearly double its pre-merger headcount of around 39,000, reflecting the scale added by combining with DS Smith's European operations.
What They Do & How They Make Money
International Paper makes money primarily by growing and buying wood fiber, converting it into containerboard (the paperboard used to make cardboard boxes), and then converting that containerboard into corrugated boxes and other packaging products that it sells to businesses that need to ship and package goods — everything from food and beverage companies to agricultural, industrial, and e-commerce customers. Its business is fundamentally a manufacturing and logistics operation: it operates paper mills that produce linerboard, medium, whitetop, and saturating kraft paper, and separate "converting" facilities that turn that raw containerboard into finished corrugated boxes and specialty packaging tailored to a customer's product. Revenue is driven by volumes (how many boxes and how much containerboard it sells) and by containerboard/box pricing, which moves with industry supply-demand dynamics and input costs (wood fiber, energy, chemicals, and freight). Historically the company also had a large printing/communications paper business and a cellulose fibers (specialty pulp) business, but it has divested non-core assets — including agreeing to sell its global cellulose fibers business to American Industrial Partners for about $1.5 billion in 2025 — to focus squarely on fiber-based packaging.
Business Segments
Following the DS Smith acquisition and portfolio simplification, International Paper now reports primarily through two geographic packaging segments, plus a small corporate category:
- Packaging Solutions North America — The company's largest segment by far, covering containerboard production (linerboard, medium, whitetop, saturating kraft) and corrugated box/packaging converting operations across the US, Canada, and parts of Latin America. FY2025 revenue was about $15.2 billion (roughly $14.9 billion TTM), representing roughly two-thirds of total company revenue.
- Packaging Solutions EMEA — Covers fiber-based packaging operations across Europe, the Middle East, and North Africa, built out substantially through the DS Smith acquisition, which added significant European scale and customer relationships. FY2025 revenue was about $8.5 billion (roughly $9.2 billion TTM), and this segment's revenue share has been growing as DS Smith's contribution ramps to a full year.
- Corporate — A minor residual category (a few million dollars in reported revenue) covering unallocated corporate items rather than an operating business.
Segment-level operating income is not detailed in the sources used here, but North America has historically been the more profitable and mature segment, while the EMEA segment (freshly expanded via DS Smith) represents the company's primary growth and integration opportunity going forward.
Competitors
- North American containerboard/corrugated packaging: Smurfit WestRock (formed from the 2024 merger of Smurfit Kappa and WestRock) is International Paper's largest and most direct rival in scale and geographic overlap; Packaging Corporation of America (PCA) and Georgia-Pacific (owned by Koch Industries) are other major US competitors in containerboard and corrugated packaging.
- Broader packaging: Sealed Air Corporation and Sonoco Products compete in adjacent protective and specialty packaging categories.
- European packaging (via DS Smith operations): Mondi and Smurfit WestRock's European operations are the primary competitors in EMEA fiber-based packaging.
Competitive Position
International Paper's moat comes from vertical integration and scale: owning both fiber supply and mills alongside converting/box-making operations lets it capture margin at multiple stages of the packaging value chain and gives it cost advantages that smaller, non-integrated converters lack. Its scale — reinforced dramatically by the DS Smith deal, which added meaningful European market share — gives it purchasing power, broad geographic reach for multinational packaging customers, and the ability to invest in large, capital-intensive mills that are expensive for new entrants to replicate. The DS Smith acquisition (2025) and the earlier Temple-Inland acquisition (2012, $4.5 billion) reflect a long-running consolidation strategy in an industry where scale drives efficiency, echoing the same consolidation logic that produced its chief rival, Smurfit WestRock.
Key risks include cyclicality: containerboard and box demand tracks broader economic activity (industrial production, e-commerce shipping volumes, consumer goods demand), and pricing for containerboard is set largely by industry-wide supply and demand, meaning IP has only partial control over its own margins. Input costs — particularly wood fiber, energy, and chemicals — can be volatile and squeeze margins when pricing doesn't keep pace. The company also carries integration risk from digesting DS Smith, a large, complex, cross-border acquisition that will take time to fully realize projected synergies, and legacy liabilities such as asbestos-related litigation from historical operations. Its recent divestiture of the cellulose fibers business signals a deliberate strategic narrowing to pure-play fiber-based packaging, which should sharpen focus and capital allocation but also removes a diversification cushion the company previously had. Overall, IP's position as one of the largest global players in a scale-driven, consolidating industry is a genuine structural advantage, but its earnings remain sensitive to macroeconomic cycles and containerboard pricing dynamics largely outside its control.
