FY25 revenue $28.27B (+39% on full-year combined Smurfit Kappa + WestRock); op income $1.60B; NI $660M; EPS $1.23. FY adj EBITDA $4.939B; Q4 adj EBITDA $1.172B.

FY26 Q1 adj EBITDA $1.1B-$1.2B; FY26 adj EBITDA $5.0B-$5.3B.

Key takeaways

  • FY adj EBITDA $4.94B — first full year as combined Smurfit Westrock. The merger (closed July 2024) is fully integrated. Combined company is the global #1 packaging player by scale + footprint + customer base. The $4.94B FY25 adj EBITDA establishes the baseline; medium-term plan targets $7B adj EBITDA by 2030 = 7% CAGR + >300bp margin expansion.
  • Three regions delivering distinct economics: North America $651M Q4 / 14.7% margin; Europe $438M / >16%; Latin America $130M+ / >24%. The geographic + product mix dispersion is structural — Latin America consistently highest-margin (paper-based packaging premium + cost discipline + market position); Europe expanding margins; North America focused on replacing uneconomic business + portfolio optimization.
  • FY26 adj EBITDA $5.0-$5.3B (+1-7% from $4.94B FY25). Conservative midpoint reflects continued integration + market conditions. Q1 FY26 $1.1-$1.2B = sequential normalization. Multi-year compounding toward $7B by 2030.
  • Leverage reduced to 2.6x; target 2x. Successful refinancings + bond redemptions + cash generation. Capital structure repair on schedule. As leverage approaches 2x, capital return capacity expands (potentially M&A or buyback acceleration).
  • Q4 adj FCF $679M / FY >$1.5B. Strong cash generation. Dividend +5% — capital return discipline maintained. Portfolio optimization (La Tuque SBS closure) continues.

Business

The earnings progression includes the WestRock merger (closed July 2024 — partial year) and FY25 first full combined year. The $28.27B FY25 revenue reflects 12 months combined vs FY24's partial 6 months; FY26 will be the first comparable year.

GAAP op margin 5.7% FY25 reflects merger amortization + integration costs + asset impairments (La Tuque SBS closure). Adj EBITDA $4.94B is the cleaner operating signal — adj EBITDA margin ~17.5%.

Total debt $12.65B (-7% YoY) — meaningful deleveraging. FCF $1.02B (from $17M FY24) reflects integration completion + cash improvement programs.

Capital allocation

  • Capex $-1.87B FY25 (+27% YoY). Combined company capex level. FY26 will continue at similar pace.
  • Dividends $-766M FY25 (+18% YoY); +5% per-share raise. Dividend is key pillar.
  • Buybacks $0 FY25 (vs $-27M FY24).
  • Debt $12.65B (-7% YoY); leverage 2.6x (target 2x).
  • FCF $1.02B (vs $17M FY24, transformational improvement).

FY26 outlook (per Q4 2025 call, 2026-02-11)

The +7% CAGR to $7B EBITDA by 2030 is the multi-year compounding setup. Combined with >300bp margin expansion = adj EBITDA margin trajectory from ~17.5% FY25 → ~20.5% by 2030. FCF + dividend + selective buybacks as leverage approaches target.

Key risks

Difficult market conditions across many countries. Q4 mgmt called out. Paper + packaging demand correlated to global economic activity + e-commerce + retail consumption. Continued market softness extends.

Weather events impact (Europe + US). Q4 mgmt called out. Severe weather affects production + transportation + customer demand. Multiple weather events FY25.

Paper market situation uncertainties. Containerboard prices + recovered fiber prices + virgin pulp prices + freight rates all dynamic. Cost-pass-through timing affects margin.

Integration challenges. Smurfit Kappa + WestRock combination is complex — different cultures, IT systems, customer relationships, regulatory regimes. Multi-year integration risk.

Customer concentration. Top customers (large CPG, e-commerce, food/beverage) drive significant revenue. Customer-level decisions affect volumes + pricing.

E-commerce demand cycle. Containerboard demand correlated to e-commerce volumes. E-commerce growth pace + return rate + secondary packaging dynamics affect demand.

FX volatility. Multi-currency operations across NA, Europe, Latin America — Euro, GBP, BRL, MXN translation affects reported results.

Capacity additions / industry supply. Industry-wide capacity additions could compress prices. Industry rationalization (e.g., La Tuque SBS closure) supports margins.

Energy + raw material costs. Pulp + recovered fiber + chemicals + energy all affect margins. European energy costs structurally elevated post-2022 crisis.

Regulatory environment. EU regulations on packaging + recycling + plastics + carbon emissions all affect operations. US state-level recycling rules also matter.

Refinancing schedule. $12.65B debt + multi-year refinancing schedule. Interest rate environment matters.

Synergy delivery. Cost + commercial synergies from merger require multi-year execution. Underperformance affects margin trajectory.

Latin America cyclical / FX. Highest-margin region but smallest. Latin America macro + currency + political dynamics introduce volatility.

Bottom line

Smurfit Westrock FY25 is the first full year as combined entity: revenue $28.27B (+39% on full-year combination), op income $1.60B, NI $660M, EPS $1.23. Adj EBITDA $4.94B FY25 / Q4 $1.17B; adj FCF >$1.5B FY / Q4 $679M. Three regions delivering: North America $651M Q4 / 14.7% margin; Europe $438M / >16% (expanding); Latin America $130M+ / >24% (highest). Leverage reduced to 2.6x (target 2x). Dividend +5%.

FY26 guide: Q1 adj EBITDA $1.1-$1.2B; FY $5.0-$5.3B (+1-7%); medium-term $7B by 2030 (7% CAGR + >300bp margin expansion). Multi-year compounding setup with strong forward visibility.

The risks are real — difficult market conditions, weather events, paper market dynamics, integration challenges, customer concentration, e-commerce cycle, FX, capacity additions, energy + raw material costs, regulatory, refinancing schedule, synergy delivery, Latin America cyclical / FX.

But the structural thesis (global #1 paper-based packaging + Smurfit Kappa + WestRock combined scale + three-region diversification + Latin America premium economics + Europe margin expansion + North America portfolio optimization + medium-term $7B EBITDA target + balance sheet repair on schedule + dividend discipline) is intact and FY25 print confirms.

Quality global paper-based packaging compounder mid-merger-integration cycle. The $4.94B FY25 EBITDA → $5.0-$5.3B FY26 → $7B by 2030 trajectory creates a multi-year compounding setup. The Latin America 24%+ margin floor + Europe 16%+ margin expansion + leverage normalization + dividend discipline provides multiple paths to outperformance. Investors get exposure to global packaging consolidation + e-commerce demand + cost synergies + Latin America premium + capital return discipline.
