Introduction
Smurfit WestRock finished its first full year as a combined firm in 2025, and the numbers confirm it is now the largest packaging firm in the world by revenue, with $31.2 billion in net sales, more than 30% ahead of its closest rival, International Paper. Meanwhile, International Paper, which itself just completed absorbing DS Smith to build European reach, declared in January 2026 that it will split back into two independent firms, while Amcor, the world's largest flexible packaging firm, followed an entirely different consolidation path by acquiring Berry Global.
This report draws entirely on each firm's own SEC and regulatory filings, official earnings releases, and annual reports to compare Smurfit WestRock against International Paper, Amcor, Graphic Packaging, Packaging Corporation of America, and Mondi, mapping who is actually largest, most profitable, and best positioned after the most consolidated 18 months in the packaging industry's recent history.
Key Takeaways
- Smurfit WestRock is the largest firm in the global packaging peer set by revenue, generating $31.2 billion in net sales for fiscal year 2025, thus more than 30% larger than its closest competitor, International Paper ($23.63 billion).
- Smurfit WestRock posted a 15.8% Adjusted EBITDA margin in FY2025 of nearly $4.939 billion, the highest among the six major packaging firms compared in this report, alongside $1.501 billion in Adjusted Free Cash Flow.
- International Paper declared on January 29, 2026, that it plans to split into two independent, publicly traded firms, one for North America, one for EMEA, less than two years after obtaining DS Smith to build its European scale in the first place.
- International Paper reported a full-year 2025 net loss of $3.37 billion despite $23.63 billion in net sales, driven by nearly $2.47 billion in pre-tax special items and then impairment charges, a stark contrast to Smurfit WestRock's $699 million net income on a smaller relative scale.
- Amcor, the world's largest dedicated flexible packaging firm at $15.0 billion in FY2025 revenue, functions in a structurally different category from Smurfit WestRock, flexible plastic and film packaging rather than fiber-based corrugated and containerboard, meaning the two firms are not direct competitors despite both ranking among the industry's largest players.
- Packaging Corporation of America (PCA), North America's third-largest containerboard producer, thus grew net sales from $8.38 billion in 2024 to $8.99 billion in 2025 after integrating the acquired Greif containerboard business, which expanded to 10 mills and 91 corrugated product plants.
- Graphic Packaging's net sales declined 2% to $8.617 billion in 2025, from $8.807 billion in 2024, with the firm's CEO citing "consumer affordability" challenges and competitive pressure as near-term headwinds facing its cartonboard business.
- Mondi, Europe's most balanced major packaging firm, split its 2025 revenue almost evenly between Corrugated Packaging (€3.8 billion, +7%) and Flexible Packaging (€3.9 billion, -1%), reporting total Group revenue of €7.663 billion.
- Smurfit WestRock employs nearly 97,000 people across 40 countries, more than Amcor (77,000 employees, 36+ countries) or International Paper (65,000+ employees, 30+ countries), thus reflecting both its larger revenue base and its more labor-intensive integrated mill-to-converting operating model.
- The packaging industry has undergone a historic wave of consolidation along with restructuring since mid-2024: the Smurfit Kappa-WestRock merger, International Paper's acquisition of DS Smith, PCA's integration of Greif's containerboard business, Mondi's acquisition of Schumacher's Western Europe assets, and now International Paper's planned split into two companies.
Visual Intelligence: 15 Data Stories Comparing Smurfit WestRock to Its Packaging Peers
Smurfit WestRock Leads the Global Packaging Peer Set by Revenue

This chart ranks major global packaging companies by full-year 2025 revenue, based on each company's own official earnings releases and SEC/regulatory filings.
- Smurfit WestRock plc: $31.2 billion. It was formed through the mega-merger of Smurfit Kappa and WestRock; this entity is the absolute global powerhouse in fiber-driven and corrugated packaging.
- International Paper Company: $23.63 billion. It is backed by its massive acquisition of DS Smith Plc, completed early in the year; the firm recorded a major leap in annual sales for its financial year.
- Amcor plc: $15 billion. Amcor's fiscal year 2025 reached over $15 billion, which partially included the landmark all-stock acquisition of Berry Global, which was finalized.
Key Insight: Smurfit WestRock's revenue lead over International Paper is itself larger than the entire annual revenue of Mondi, the smallest firm in this comparison, illustrating just how much scale the July 2024 Smurfit Kappa-WestRock combination created in a single transaction.

Smurfit WestRock's FY2025 Financial Profile

This chart summarizes Smurfit WestRock's fiscal 2025 net sales, Adjusted EBITDA, net income, and Adjusted Free Cash Flow, based on the company's own official earnings release.
Smurfit WestRock reported full-year fiscal 2025 net sales of $31,2 billion, an Adjusted EBITDA of $4,9 billion, a net income of $0.7 billion, and an Adjusted Free Cash Flow of $1,5 billion.
Key Insight: By generating $1.5 billion in Adjusted Free Cash Flow while nearly funding $2.4-$2.8 billion in annual capital expenditure demonstrates the firm has moved well past the typical post-merger integration phase and into genuine self-funded growth investment, a notable achievement just eighteen months after closing one of the packaging industry's largest-ever combinations.

How Smurfit WestRock Was Formed: The Smurfit Kappa-WestRock Merger
| Date | Key Milestone |
| Sep-23 | Smurfit Kappa and WestRock announce agreement to combine |
| Jun-24 | Shareholders of both companies approve the combination |
| Jul 5, 2024 | Combination closes; Smurfit WestRock begins trading |
| 2025 | First full year as a combined company; $400M synergy target exceeded |
| Feb-26 | FY2025 results reported; company outlines approximately $7B EBITDA target by 2030 |
This timeline traces Smurfit WestRock's formation from the September 2023 merger announcement through its February 2026 full-year results and 2030 strategic targets.
- In September 2023, Smurfit Kappa and WestRock announced an agreement to combine.
- In June 2024, shareholders of both companies approved the combination.
- In July 2024, the combination closed, and Smurfit WestRock began trading.
- In 2025, in the first full year as a combined company, the synergy target of $400M was exceeded.
- In February 2026, reports on FY2025 results were released.
Key Insight: Exceeding the $400 million committed synergy target within the firm's first full year as a combined entity, while simultaneously decreasing its North American workforce by more than 4,600 people, suggests the merger's integration was executed faster than many comparably sized cross-border packaging combinations, thus setting a higher bar for International Paper's own DS Smith integration happening on a similar timeline.

International Paper's FY2025: The Closest Competitor by Scale

This chart summarizes International Paper's total FY2025 net sales and its two operating segments, Packaging Solutions North America and EMEA, and Adjusted EBITDA, based on the firm's own earnings release.
- Total net sales: $23.63B. Price drops applied at checkout, like early-payment incentives for seasonal markdowns, corporate clients, or bulk-order discounts.
- Packaging Solutions North America: $15.18B. Meanwhile, Packaging Solutions EMEA: $8.45B.
- Adjusted EBITDA: $2.98B, which comes down to how the company stripped away massive, one-time structural expenses to show its true core operating profitability.
Key Insight: Packaging Solutions North America alone such as $15.175 billion, is larger than Amcor's entire global revenue, stating that even after IP's planned split into two independent firms, the resulting North American entity would still rank as one of the industry's largest standalone packaging firms in its own right nearly half the size of Smurfit WestRock, but larger than PCA, Graphic Packaging, or Mondi individually.
Source: International Paper Company - "Reports Full-Year and Fourth Quarter 2025 Results", January 29, 2026.
International Paper's Historic Announcement: Splitting Into Two Companies
This is a direct quote from International Paper's Chairman and CEO announcing the company's plan to separate into two independent, publicly traded packaging companies for North America and EMEA.
- North American Entity: It retains the International Paper name, aiming exclusively on North American packaging solutions using combined legacy IP as well as DS Smith assets.
- EMEA Packaging Entity: It operates as a standalone business across 30 countries in Europe, the Middle East, and Africa, combining legacy DS Smith and even IP assets in the region.
Key Insight: The timing is genuinely striking, as International Paper finished its acquisition of DS Smith in January 2025 specifically to build a larger, more competitive EMEA packaging platform, and just twelve months later declared it would separate that same platform into a standalone firm. A reversal that raises real questions about whether the original combined-company thesis has changed, or whether the acquisition's main purpose was always to build EMEA scale before an eventual separation.

Amcor: The Flexible Packaging Giant Smurfit WestRock Doesn't Directly Compete With
This highlight summarizes Amcor's global scale and core flexible packaging business, based on the firm's own corporate disclosures.
Amcor is a global leader in flexible and rigid packaging, operating in over 40 countries with more than 200 facilities and approximately 50,000 employees. Flexible packaging is the largest and most globally diversified segment of Amcor's overall business. Thus, it extends perishable food shelf life, manages medical sterility, and lowers the overall environmental footprint via lightweight, recyclable designs such as the Am Prima line. It generates over $15 billion in annual sales, serving non-discretionary consumer staples such as food and beverages.
Key Insight: Amcor's inclusion in "largest packaging companies" rankings alongside Smurfit WestRock can be misleading without this distinction, the two firms serve overlapping customer categories such as consumer goods, food and beverage but through almost entirely different substrate technologies such as flexible film versus rigid fiber-based board, meaning a user choosing between the two is typically making a packaging-format decision, not a vendor-selection decision within the same product category.

PCA: North America's Third-Largest Containerboard Producer Keeps Growing

This chart compares Packaging Corporation of America's net sales for 2024 and 2025, based on the company's own official earnings release.
Packaging Corporation of America's (PCA) total net sales for the full year 2024 were actually $8.3 billion because the need for boxes and corrugated packaging rebounded significantly compared to the destocking-heavy environment of 2023.
Packaging Corporation of America's (PCA) full-year 2025 net sales rose to approximately $8.99 billion, mainly driven by the acquisition of Greif's containerboard business, which added major production assets and contributed to higher overall sales despite generally flat organic box and corrugated product shipments for much of the year.
Key Insight: PCA's 7.3% revenue growth, achieved mainly via integrating the acquired Greif containerboard business rather than organic expansion, illustrates a bolt-on acquisition growth strategy quite different from Smurfit WestRock's or International Paper's transformational, company-scale mergers. PCA has consistently pursued smaller, more digestible acquisitions while remaining a purely North American operator.

Graphic Packaging: Cartonboard Demand Softened Slightly in 2025

This chart compares Graphic Packaging Holding Company's net sales for 2024 and 2025, based on the firm's own official earnings release.
Graphic Packaging Holding Company recorded full-year 2024 net sales of nearly $8.81 billion as the core packaging operations and bleached paperboard segments experienced lower average realized pricing and modest volume adjustments, compared to the previous year's elevated market levels.
Graphic Packaging Holding Company's net sales of nearly $8.62 billion reflect a period of normalization and slight year-over-year revenue contraction, following prior peak-demand and even acquisition-heavy growth cycles. Consumer packaged goods markets generally experienced lower volume demand and inventory destocking by major food, beverage, and even foodservice brand customers after pandemic-era surges.
Key Insight: Graphic Packaging is the only firm in this six-way comparison to report a revenue decline in 2025, and its Adjusted Net Income fell more sharply still. A reminder that even within the same broad fiber-based packaging category as Smurfit WestRock, a firm specializing specifically in cartonboard and folding cartons can face a meaningfully different need environment than one weighted more heavily toward corrugated shipping containers.

Mondi: A Rare European Player Balanced Between Corrugated and Flexible Packaging

This chart compares Mondi's 2025 segment revenue between Corrugated Packaging and Flexible Packaging, based on the firm's own full-year results announcement.
The €3.8 billion figure represents the annual revenue generated by the major packaging and paper group Mondi specifically from its Corrugated Packaging division. Brand owners are now actively replacing traditional multi-material plastics with paper-driven and mono-material solutions to meet circular economy goals.
Traditional flexible packaging depends heavily on multi-layered plastics. Because Mondi's €3.9B portfolio has specialized heavily in paper-based options and mono-material plastics, they are uniquely positioned to assist major consumer brands in replacing hard-to-recycle plastics while handling shelf life.
Key Insight: Mondi's near-even split between corrugated and flexible packaging revenue makes it structurally unique among the firms in this comparison, Smurfit WestRock, International Paper, and PCA are all overwhelmingly fiber or corrugated-focused, while Amcor is overwhelmingly flexible-focused, meaning Mondi has a genuine strategic middle ground that could position it as either an acquisition target or a consolidator, thus, depending on how European packaging M&A activity develops.

Profitability Comparison: EBITDA Margins Across Major Packaging Companies

This chart compares FY2025 EBITDA margins across four major packaging companies with disclosed figures, based on each company's own earnings releases.
The FY2025 EBITDA margins across four major packaging companies with fully disclosed figures span from nearly 12.6% to 15.8%. These metrics highlight performance disparities across metal, paperboard, and flexible packaging segments as businesses navigate changing consumer demand, input inflation, and even heavy structural integrations.
Key Insight: Smurfit WestRock's 15.8% margin, the highest in this comparison, combined with its status as the largest company by revenue, is a notably rare combination in heavy manufacturing industries, where scale and margin usually trade off against each other; sustaining both simultaneously suggests the merger's cost synergies have transformed into genuine structural efficiency rather than just larger absolute scale.
Source: Multiple (see below) - "Company FY2025 earnings releases," 2025-2026.
Smurfit WestRock Has the Largest Workforce Among Major Packaging Peers

This chart compares total employee counts across three major packaging companies with disclosed figures, based on official company disclosures. The total combined workforce across these three industry giants is nearly 239,000 employees. Due to massive global mergers and acquisitions, the individual employee counts for each firm have shifted significantly
Key Insight: Smurfit WestRock's employee count (97,000) exceeds its revenue lead over International Paper in percentage terms (97,000 vs. 65,000+ is nearly 49% more employees, compared to roughly 32% more revenue), suggesting the combined firm's operations may be somewhat more labor-intensive per dollar of revenue than IP's, though this could also reflect IP's continued restructuring and even headcount reduction actions taken throughout 2025.

Mapping the Containerboard/Corrugated Packaging Value Chain
| Value Chain Stage | Description |
| Fiber Sourcing | Virgin wood pulp and recovered/recycled fiber |
| Paper Mill Production | Linerboard and fluted medium (containerboard) |
| Converting | Corrugating, box forming, printing |
| Distribution | Shipped to CPG, commerce, and industrial customers |
| Recycling | Recovered fiber loops back to mills |
This process diagram traces the five-stage containerboard and corrugated packaging value chain, from fiber sourcing through recycling, highlighting the importance of vertical integration.
The containerboard and corrugated packaging value chain functions as a highly integrated circular loop. Vertical integration plays an important role by linking raw material sourcing directly with manufacturing, converting, and recycling, which secures supply, optimizes expenses, and thus stabilizes profit margins against volatile commodity pricing.
Key Insight: The fact that Smurfit WestRock, International Paper, and PCA all own assets across every stage of this chain, mills, converting plants, and even recycling operations rather than specializing in just one stage, is precisely why scale and integration matter so much in this industry; a firm that must purchase containerboard on the open market rather than manufacturing its own faces a structural cost disadvantage against vertically integrated competitors of the kind compared throughout this report.

Smurfit WestRock vs. Major Packaging Peers: Side-by-Side Comparison
| Company | HQ | FY2025 Revenue | Core Focus | Employees |
| Smurfit WestRock | Dublin, Ireland | $31.2B | Corrugated packaging, containerboard | ~97,000 |
| International Paper | Memphis, TN, US / London, UK | $23.63B | Packaging; splitting into NA + EMEA companies | 65,000+ |
| Amcor | Zurich, Switzerland | $15.0B | Flexible packaging (plastic/film) | 77,000 |
| Packaging Corp. of America (PCA) | Lake Forest, IL, US | $8.99B | Containerboard (North America only) | Not disclosed here |
| Graphic Packaging | Atlanta, GA, US | $8.62B | Cartonboard, folding cartons | Not disclosed here |
| Mondi | Weybridge, UK / Vienna, Austria | ~$8.38B (€7.66B) | Corrugated + flexible packaging (Europe) | Not disclosed here |
This styled comparison table profiles six major global packaging firms on headquarters, FY2025 revenue, core business focus, and employee count, based on official company disclosures. Major global packaging firms include industry leaders such as Amcor plc, International Paper, and even Smurfit WestRock, which report their operational scope and financial standing through official annual disclosures.
Key Insight: Only Smurfit WestRock and International Paper currently function as genuinely global, multi-continent integrated packaging platforms of comparable scale, and with International Paper now moving to split its own EMEA and North American operations into separate firms, Smurfit WestRock may soon stand alone as the only truly global, single-company operator of this scale in the fiber-based packaging industry.

Capital Investment Scale: Smurfit WestRock Plans to Spend Nearly 5x Mondi's Capex
This chart compares annual capital expenditure guidance between Smurfit WestRock and Mondi, based on each company's own disclosed capex plans.
- Mondi: $0.54B has grown in recent years because of a massive €1.2 billion multi-year strategic investment program programmed to expand production capacity, high-profile corporate acquisitions, and even macroeconomic cost inflation.
- Smurfit WestRock: $2.60B in funds are directed toward highly automated and specialty converting lines, along with smaller, high-volume operational efficiency projects rather than raw commodity tonnage growth.
Key Insight: Smurfit WestRock's far larger capex budget is nearly proportional to its revenue advantage over Mondi, about 3.8x Mondi's revenue versus roughly 4.8x its capex, suggesting Smurfit WestRock is currently investing at a slightly higher rate relative to its size, consistent with a firm still in the early stages of executing its post-merger 2030 growth plan, while Mondi, which actually reduced its 2026 capex guidance from an earlier €550 million estimate, thus, appears to be prioritizing capital discipline during the current industry downturn instead.

Recent Developments
Seven of the most consequential developments shaping Smurfit Westrock and the broader packaging industry over the past 18 months, thus prioritized by recency and business impact:
International Paper Company - January 29, 2026
| Date | January 29, 2026 |
| Organization | International Paper Company |
| Development | International Paper announced plans to split into two independent, publicly traded companies: one focused on North America and one on EMEA (Europe, Middle East and Africa). |
| What Changed | The announcement came alongside full-year 2025 results, thus showing net sales of $23.63 billion but a net loss of $3.37 billion, driven by nearly $2.47 billion in pre-tax special items and impairment charges. |
| Why It Matters | Reverses, within about twelve months, the geographic-scale-building logic behind International Paper's own acquisition of DS Smith, thus raising questions about whether the combined-company thesis changed or whether separation was always the intended eventual outcome. |
| Business Significance | International Paper thus guided for $3.5–$3.7 billion in adjusted EBITDA for full-year 2026, with North America delivering 37% year-over-year adjusted EBITDA improvement in the second half of 2025 alone. |

Smurfit Westrock plc - February 11, 2026
| Date | February 11, 2026 |
| Organization | Smurfit Westrock plc |
| Development | Smurfit Westrock recorded full-year 2025 results, its first complete year as a combined company, with net sales of $31.179 billion and even net income of $699 million. |
| What Changed | The firm exceeded its committed $400 million synergy target and outlined 2030 targets including approximately $7 billion in Adjusted EBITDA as well as $14 billion in cumulative discretionary free cash flow. |
| Why It Matters | It confirmed the Smurfit Kappa-WestRock combination has successfully integrated ahead of or on schedule, with North America representing nearly 60% of company earnings, which is identified as the biggest remaining value-creation opportunity in the medium-term plan. |
| Business Significance | The company declared continued portfolio optimization, including the closure of a paper machine in La Tuque, Quebec, and an associated extrusion facility, affecting approximately 90 employees. |

International Paper Company - January 23, 2026
| Date | January 23, 2026 |
| Organization | International Paper Company |
| Development | International Paper completed the sale of its Global Cellulose Fibers (GCF) business to American Industrial Partners for $1.5 billion. |
| What Changed | The GCF business is now presented as discontinued operations in International Paper's financial statements, thus separate from its continuing Packaging Solutions North America and EMEA segments. |
| Why It Matters | It represents further portfolio simplification by International Paper immediately ahead of its announced plan to split its remaining packaging business into two independent companies. |
| Business Significance | The divestiture reflects a wider pattern of International Paper narrowing its focus specifically to packaging, having already exited or declared plans to separate multiple non-core or geographically distinct businesses within a nearly twelve-month window. |

Mondi plc - February 19, 2026
| Date | February 19, 2026 |
| Organization | Mondi plc |
| Development | Mondi recorded full-year 2025 results, with Group revenue of €7,663 million (up 3% from €7,416 million in 2024) but underlying EBITDA declining to €1,001 million from €1,049 million. |
| What Changed | The firm reorganized its business units during the year, thus combining Uncoated Fine Paper with Corrugated Packaging into a single enlarged business unit. |
| Why It Matters | Revenue growth driven partly by the Schumacher acquisition masked underlying margin pressure from a prolonged cyclical downturn in European packaging markets, with underlying EBITDA margin falling from 14.1% to 13.1%. |
| Business Significance | Mondi reduced its 2026 capital expenditure guidance to €500 million (from a prior €550 million estimate), signaling a shift toward capital discipline as the company navigates challenging trading conditions. |
Source: Mondi plc, "Full Year Results 2025," February 19, 2026
Graphic Packaging Holding Company - February 3, 2026
| Date | February 3, 2026 |
| Organization | Graphic Packaging Holding Company |
| Development | Graphic Packaging reported full-year 2025 results, with net sales declining 2% to $8.617 billion and even Adjusted Net Income falling to $539 million from $759 million in 2024. |
| What Changed | The firm's President and CEO cited consumer affordability challenges and even competitive pressure as near-term headwinds affecting the cartonboard and folding carton business specifically. |
| Why It Matters | It represents the weakest financial performance among the six firms profiled in this report for fiscal 2025, thus illustrating that even within the broader fiber-based packaging category, demand conditions vary significantly by specific sub-segment (cartonboard versus corrugated shipping containers). |
| Business Significance | Fourth-quarter 2025 net sales were nearly flat year-over-year at $2.103 billion, with a $32 million decline in packaging operations sales largely offset by a $40 million favorable foreign exchange impact. |

Packaging Corporation of America - 2025 (full year)
| Date | 2025 (full year) |
| Organization | Packaging Corporation of America |
| Development | PCA reported full-year 2025 net sales of $8.99 billion, up from $8.38 billion in 2024, driven substantially by the integration of the acquired Greif containerboard business. |
| What Changed | PCA now operates 10 mills and 91 corrugated products plants, up from 8 mills and 86 plants before the Greif integration, while remaining North America's third-largest containerboard producer. |
| Why It Matters | It demonstrates PCA's continued preference for targeted, bolt-on acquisitions to grow scale within North America specifically, rather than pursuing the kind of transformational, multi-continent mergers which created Smurfit WestRock or International Paper's post-DS Smith structure. |
| Business Significance | PCA executives noted a "more positive vibe" emerging among containerboard customers entering 2026, while also assessing operational impacts from a recent winter storm. |

Mondi plc - March 31, 2025
| Date | March 31, 2025 |
| Organization | Mondi plc |
| Development | Mondi finished the acquisition of Schumacher Packaging's Western Europe Packaging Assets for total cash consideration of €506 million. |
| What Changed | The acquisition included two state-of-the-art mega-box plants in Germany, thus expanding Mondi's geographic reach and containerboard integration in Western Europe. |
| Why It Matters | It contributed €292 million of revenue to Mondi's 2025 results, though the acquired operations incurred a €29 million after-tax loss during the period, thus illustrating the near-term financial drag that can accompany even strategically sound bolt-on acquisitions during an industry downturn. |
| Business Significance | It represents one of several mid-sized packaging acquisitions completed across the industry in 2025, alongside PCA's Greif integration, thus occurring in parallel with the larger transformational combinations at Smurfit WestRock and International Paper. |
