Plastic and flexible packaging substitution - rigid plastics and pouches gaining 50-100bps annual share in food/beverage and consumer goods, though sustainability regulations (EU plastic taxes, extended producer responsibility) favor fiber-based solutions
Digital commerce shift reducing secondary packaging needs - direct-to-consumer brands using 20-30% less corrugated per unit versus traditional retail distribution, though total e-commerce volume growth offsets this efficiency
Containerboard capacity additions - 1.2M tons of new North American capacity announced for 2025-2027 could pressure pricing if demand growth disappoints, though 800K tons of high-cost capacity retired 2022-2024
International Paper (25% North American containerboard share) and Packaging Corporation of America (18% share) pricing discipline - industry history of periodic price wars when utilization falls below 88%, most recently 2019 saw $80/ton declines
Private equity-backed converters (Pratt Industries, Georgia-Pacific) expanding with 100% recycled mills at $600-700/ton cash costs versus integrated players at $400-500/ton, capturing price-sensitive customers
Amazon backward integration - owns 2 containerboard mills and 100+ box plants producing 15-20% of internal needs, potential to expand threatens 8-10% of SW revenue if fully internalized

Pension obligations of $1.8B underfunded status (legacy WestRock plans) requiring $150-200M annual cash contributions through 2028, consuming 10-15% of operating cash flow
Integration execution risk - $400M synergy target requires closing 15-20 redundant facilities and 3,000+ headcount reduction, potential for operational disruptions or labor disputes during 2025-2026 implementation
