• Mixed Q1 Financial Performance

  Reported GAAP diluted EPS decreased by 15.5% to $1.91 in Q1 2026 from $2.26 in Q1 2025. However, excluding $44.3 million in special items (net of tax), adjusted diluted EPS increased by 3.9% to $2.40 from $2.31.

• Sales Growth Driven by Acquisition

• Significant Restructuring Charges

  Q1 2026 results included $53.3 million in pre-tax restructuring charges related to the permanent shutdown of the No. 2 paper machine and kraft pulping facilities at the Wallula, Washington mill.

• Increased Interest Expense

  Interest expense, net, significantly increased to $32.6 million in Q1 2026 from $12.9 million in Q1 2025, primarily due to financing for the Greif acquisition.

auto_awesomeAnalysis

Packaging Corp of America reported a 15.5% decrease in GAAP diluted EPS for Q1 2026 compared to Q1 2025, primarily due to significant special items totaling $44.3 million (net of tax). These special items included charges from the Wallula mill restructuring and acquisition-related costs from the Greif acquisition. Excluding these special items, diluted EPS increased by 3.9%. The Greif acquisition, completed in September 2025, contributed to a 10.6% increase in net sales but also led to higher depreciation and interest expenses, resulting in a net loss from the acquired business in Q1 2026. The company also repurchased $58.8 million in common stock during the quarter. Management's outlook for Q2 2026 is cautious, anticipating lower earnings (excluding special items) due to higher mill maintenance outage expenses, increased freight, fiber, and chemical costs, and a higher tax rate. This mixed performance, coupled with a negative short-term outlook, suggests ongoing operational adjustments and cost pressures.
