Insights

Industrial equities analyst

PKG is taking a sizable restructuring hit to shut legacy capacity at Wallula.

Packaging Corporation of America plans to permanently close the No. 2 paper machine and kraft pulping facilities at its Wallula, Washington mill while maintaining the No. 3 paper machine and recycled pulping. This targets specific containerboard capacity rather than an entire site exit.

The company expects pre-tax restructuring charges of $205 million, with about $165 million as non-cash impairment and accelerated depreciation and $40 million as cash costs for contract termination, severance, and other items. Most of these charges will be recorded in Q4 2025 and Q1 2026, so near-term reported earnings will be meaningfully affected by one-time items.

The plan includes eliminating roughly 200 positions, indicating a material workforce reduction at Wallula. Future financial disclosures for Q4 2025 and Q1 2026 will show how these restructuring charges flow through operating income and whether ongoing operations at the No. 3 machine and recycled pulping facilities stabilize profitability at the mill.
