Smurfit Westrock Plc: Q3 2025 Financial Summary

Business Context and Reporting Period

This Form 10-Q covers the quarterly period ended September 30, 2025. Smurfit Westrock Plc is a multinational provider of sustainable fiber-based paper and packaging solutions. The reporting reflects the combined operations following the July 5, 2024, Combination of Smurfit Kappa and WestRock. Smurfit Kappa was the accounting acquirer; therefore, comparative periods prior to July 2024 reflect Smurfit Kappa's historical results, while current periods reflect the consolidated entity.

Key Financial Metrics

Material Changes vs. Prior Period

• Revenue Growth: Net sales increased 4.3% in Q3 and 73.8% over nine months, driven primarily by the inclusion of WestRock operations (approx. $270M in Q3 and $9.8B in 9M). Excluding the acquisition, organic sales were impacted by lower volumes but supported by higher selling price mixes and favorable foreign currency effects.
• Profitability: Net income swung from a loss of $150M in Q3 2024 to a profit of $246M in Q3 2025. This improvement is largely due to the scale of the combined entity and the absence of significant transaction costs in the current period compared to the prior year.
• Restructuring & Impairment: Impairment and restructuring costs rose significantly to $65M in Q3 (vs. $21M prior year) and $360M for nine months (vs. $21M prior year). This was driven by the April 2025 announcement to close the St. Paul, MN coated recycled board mill, the Forney, TX containerboard mill, and two converting facilities in Germany.
• Transaction Costs: Transaction and integration expenses decreased to $15M in Q3 2025 from $267M in Q3 2024, as the bulk of Combination-related costs were incurred in the prior year.
• Interest Expense: Net interest expense increased to $177M in Q3 (vs. $167M) and $526M for nine months (vs. $225M), reflecting debt assumed and issued in connection with the Combination.

Guidance, Outlook, and Risks

• Capacity Reduction: The company is executing a plan to reduce capacity by over 500,000 tons through the closure of U.S. and German facilities. Management expects these closures to match supply with demand and increase overall profitability by eliminating fixed costs, excluding the one-time impairment charges.
• Dividends: The Board approved a quarterly dividend of $0.4308 per share, payable December 18, 2025.
• Internal Controls: Management concluded that disclosure controls and procedures were not effective as of September 30, 2025, due to a material weakness in internal control over financial reporting. This weakness stems from the integration of Smurfit Kappa and WestRock legacy control frameworks, specifically regarding documentation of management reviews, manual journal entries, and General IT Controls. A remediation plan is underway.
• Legal & Contingencies:
  • Brazil Tax: A dispute regarding goodwill amortization totaling $146M remains pending, though a federal court recently ruled in the company's favor for the 2003-2008 period (under appeal).
  • Antitrust: The company is a defendant in a U.S. class action lawsuit alleging price-fixing in containerboard and linerboard markets. The parent company was voluntarily dismissed without prejudice in October 2025, but subsidiaries remain defendants.
  • Venezuela Arbitration: An award of over $469M plus interest was granted in August 2024; enforcement proceedings are ongoing while Venezuela seeks annulment.
• Market Risks: Key risks include macroeconomic uncertainty, inflation, raw material and energy costs, geopolitical fragmentation (tariffs), and the ability to achieve synergies from the Combination.

Investor Verification Checklist

• Verify the progress and cost of the remediation plan for the material weakness in internal controls over financial reporting.
• Monitor the execution of facility closures (St. Paul, Forney, Germany) and the realization of anticipated cost savings versus the $360M in impairment/restructuring charges.
• Assess the impact of the U.S. antitrust class action lawsuit on subsidiaries and potential liability exposure.
• Review the resolution status of the Brazil tax dispute and the Venezuela arbitration award enforcement.
• Track the company's ability to pass on raw material and energy cost increases to customers given the lag in price realization.
• Confirm the sustainability of Adjusted EBITDA growth excluding the one-time benefits from the prior year's inventory step-up amortization.
