Income Statement Analysis: The Bottom-Line Duel
This comparison exposes which company runs a more efficient and profitable business engine through their recent income statement performance.
Smurfit Westrock Plc Analysis
Smurfit Westrock posted a strong revenue surge of 86% in 2024, reaching $20.4B, but net income plummeted 78% to $308M. Its gross margin held steady near 20%, yet net margin contracted to 1.5%, signaling rising costs eroding bottom-line gains. Despite revenue momentum, the sharp decline in profitability reflects operational inefficiencies and higher expenses.
Packaging Corporation of America Analysis
Packaging Corp grew revenue modestly by 7% to $9B in 2025, while net income dipped 4% to $769M. It maintained robust gross and EBIT margins above 21% and 12%, respectively. The net margin of 8.5% remains healthy, underscoring disciplined cost control and steady earnings quality amid moderate top-line expansion.
Margin Resilience vs. Revenue Explosion
Smurfit Westrock’s explosive revenue growth contrasts with sharply deteriorating profitability, while Packaging Corp shows slower revenue gains but stronger margin preservation. Packaging’s higher net margin and EBIT efficiency make it the fundamental winner in operational discipline. Investors favor a stable, margin-focused profile over volatile revenue-driven performance.

Efficiency & Valuation Duel: The Vital Signs
Ratios act as a company’s DNA, revealing hidden risks and operational excellence that drive investment decisions with clarity and precision.
Smurfit Westrock Plc
Smurfit Westrock shows weak profitability with a 1.77% ROE and slim 1.51% net margin, signaling operational challenges. Its P/E of 67.5 marks the stock as stretched, while a modest 3.13% dividend yield offers steady shareholder returns. The firm balances reinvestment with cautious capital allocation amid neutral leverage metrics.
Packaging Corporation of America
Packaging Corp posts a neutral 8.55% net margin but zero reported ROE and ROIC raise concern over profitability quality. The 30.6 P/E suggests an expensive valuation. Strong interest coverage (13.99) and a 2.42% dividend yield highlight solid financial health and shareholder rewards, despite incomplete liquidity data clouding full assessment.
Premium Valuation vs. Operational Safety
Smurfit Westrock’s stretched valuation contrasts with its weak returns, while Packaging Corp offers better operational safety but incomplete liquidity data. Packaging’s profile suits investors prioritizing income and coverage; Smurfit Westrock’s risks may fit those chasing growth despite thin profitability.
Which one offers the Superior Shareholder Reward?
I see Smurfit Westrock Plc (SW) yields 3.13% with a high payout ratio over 210%, suggesting dividend sustainability risks. Packaging Corporation of America (PKG) offers a 2.42% yield but maintains a prudent 74% payout ratio. PKG’s buybacks are robust, driving free cash flow per share to 5.85 vs. SW’s 0.04, signaling stronger capital returns. SW’s dividend and buyback coverage are weak, risking future cuts. PKG’s balanced distribution and solid cash flow support a more sustainable, superior total shareholder return in 2026. I favor PKG for disciplined capital allocation and enduring value creation.
Comparative Score Analysis: The Strategic Profile
The radar chart reveals the fundamental DNA and trade-offs of Smurfit Westrock Plc and Packaging Corporation of America:
Smurfit Westrock shows a more balanced profile with strong discounted cash flow (DCF) at 5 and moderate scores across ROE (2), ROA (2), debt-to-equity (2), and valuation metrics (PE 2, PB 3). Packaging Corporation lags with generally very unfavorable scores except for moderate PE (2), relying on no clear edge but showing weaker operational efficiency and financial stability. Smurfit Westrock’s diversified strengths suggest better resilience in this sector’s cyclical environment.
Bankruptcy Risk: Solvency Showdown
The Altman Z-Score delta indicates stark differences in solvency risk:
Packaging Corporation sits safely in the “safe zone” with a Z-score of 3.84, signaling low bankruptcy risk. In contrast, Smurfit Westrock’s 1.34 places it deep in the “distress zone,” raising red flags about long-term survival amid economic fluctuations. This gap demands caution for Smurfit Westrock investors despite its operational strengths.
Financial Health: Quality of Operations
Piotroski F-Scores highlight internal financial quality comparisons:
Smurfit Westrock scores 5, while Packaging Corporation scores slightly lower at 4, both indicating average financial health. Neither company exhibits peak financial strength, but Smurfit Westrock’s marginally better score suggests marginally stronger profitability and efficiency metrics. Investors should monitor these metrics closely for signs of improvement or deterioration.

Packaging Corporation of America shows a more balanced mix: Packaging at $7.69B, Paper at $625M, plus a $90M Corporate segment. Westrock’s dominance in Packaging signals ecosystem lock-in, whereas Packaging Corp’s diversified streams reduce concentration risk but lack Westrock’s scale in any single segment.

Smurfit Westrock Plc Strengths

The Moat Duel: Analyzing Competitive Defensibility
A structural moat alone protects long-term profits from relentless competitive erosion. Let’s dissect the defensive strengths of Smurfit Westrock and Packaging Corporation of America:
Smurfit Westrock Plc: Scale and Diversified Product Moat
Smurfit Westrock leverages broad geographic reach and product diversity to maintain switching costs for clients. However, its declining ROIC signals weakening capital efficiency. Expansion into emerging markets could either deepen or strain this moat in 2026.
Packaging Corporation of America: Operational Efficiency Moat
Packaging Corp. relies on cost advantage and operational excellence, showing consistent margin superiority versus peers. While ROIC data is limited, steady revenue growth and margin stability suggest a resilient moat. Innovation in specialty packaging may fuel future gains.
Scale and Diversification vs. Operational Excellence: The Moat Verdict
Smurfit Westrock’s wide moat stems from scale but suffers from deteriorating capital returns. Packaging Corp.’s narrower but sharper cost moat drives superior margins and growth consistency. I find Packaging better positioned to defend its market share going forward.

Risks specific to each company
The following categories identify the critical pressure points and systemic threats facing both firms in the 2026 market environment:
1. Market & Competition
Smurfit Westrock Plc
- Faces intense global competition with moderate market share; margin pressure evident from low net margin and ROIC.
Packaging Corporation of America
- Operates mainly in the US with strong niche focus, but zero ROIC and ROE signal operational challenges.
2. Capital Structure & Debt
Smurfit Westrock Plc
- Moderate leverage with debt-to-equity at 0.78 and interest coverage of 2.62; manageable but watch liquidity ratios.
Packaging Corporation of America
- Debt metrics not reported but very favorable interest coverage of 13.99 suggests strong capacity to service debt.
3. Stock Volatility
Smurfit Westrock Plc
- Beta near 1.0 indicates market-level volatility; trading range moderate but elevated P/E of 67.5 adds valuation risk.
Packaging Corporation of America
- Lower beta at 0.9 implies less volatility; trading near 52-week high but P/E of 30.6 still signals stretched valuation.
4. Regulatory & Legal
Smurfit Westrock Plc
- International operations expose firm to diverse regulatory regimes, increasing compliance complexity and legal risk.
Packaging Corporation of America
- US-centric operations reduce regulatory complexity but face stringent environmental and labor regulations domestically.
5. Supply Chain & Operations
Smurfit Westrock Plc
- Global supply chain vulnerable to geopolitical disruptions; asset turnover and fixed asset turnover are weak, signaling operational inefficiency.
Packaging Corporation of America
- More localized supply chain reduces disruption risk; however, asset turnover data missing, raising transparency concerns.
6. ESG & Climate Transition
Smurfit Westrock Plc
- ESG pressures rising globally; paper-based packaging demands sustainable sourcing and carbon reduction, challenging cost structures.
Packaging Corporation of America
- Faces similar ESG demands but with stronger US regulatory push; potential for higher compliance costs impacting margins.
7. Geopolitical Exposure
Smurfit Westrock Plc
- Significant exposure to European and global markets increases risk from trade tensions and currency fluctuations.
Packaging Corporation of America
- Primarily US-focused, limiting geopolitical risks but dependent on domestic economic and policy stability.
Which company shows a better risk-adjusted profile?
Smurfit Westrock’s greatest risk lies in operational inefficiency and global regulatory complexity. Packaging Corporation of America’s key risk is poor profitability and unclear asset utilization. Despite slightly unfavorable ratings for both, Packaging’s strong balance sheet and safer Altman Z-Score indicate a better risk-adjusted profile. The stark contrast in Altman Z-Scores—1.34 (distress zone) for Smurfit Westrock versus 3.84 (safe zone) for Packaging—justifies heightened caution on Smurfit Westrock’s financial distress potential.
Final Verdict: Which stock to choose?
Smurfit Westrock Plc’s superpower lies in its operational scale and recent revenue surge, signaling potential to leverage market opportunities. Yet, its declining profitability and value destruction over time pose a point of vigilance. It fits an aggressive growth portfolio willing to weather volatility for upside potential.
Packaging Corporation of America commands a strategic moat through strong operational margins and disciplined capital allocation, offering a more stable earnings profile. Its solid balance sheet and better bankruptcy risk standing make it suitable for GARP investors seeking quality with measured growth.
If you prioritize aggressive expansion and can tolerate declining returns, Smurfit Westrock Plc presents a compelling scenario due to its scale and top-line momentum. However, for those seeking stability and capital efficiency within growth, Packaging Corporation of America offers better resilience and a stronger financial foundation, despite commanding a premium.
