Packaging Corporation of America

The filings describe a larger company with a tighter link between earnings and cash than the net income line alone suggests. Operating cash flow of $1.56 billion was 2.01 times net income of $774.1 million. The Beneish M-Score of -2.649 is below the -1.78 threshold, so the label reads not in the elevated zone. That is a screening result built from ratios, not proof that the reported figures are accurate, and it does not examine individual transactions. The Altman Z-Score here is the Z double-prime variant, reading 4.02, which sits in the safe zone. The Piotroski F-Score is 4 of 9 computable signals, meaning four of the nine standard checks were met. The Fog Index of 15.19 falls in the hard-to-read band, which matters because the MD&A is where management explains the Greif Acquisition, the Wallula mill restructuring, and the shift in fiber mix. Readers may want to look at how those items affect the 2026 cost base, which the risk factors quantify only in part. A $10 per ton increase in recycled fiber would add about $20 million of expense based on 2026 estimated consumption, and a $0.10 per million MMBTU increase in natural gas prices would add about $3 million based on 2025 usage. The Paper segment's reliance on ODP is paired with a contract that runs through December 31, 2026, followed by a two-year phase-down. The shift toward electronic alternatives, which the risk factors say is reducing demand for UFS paper products, adds to that concentration. Management's growth narrative is supported by the revenue and operating cash flow figures, but the rise in long-term debt and the year-over-year decline in net income are the numbers a careful reader should weigh alongside it.

Catalyst.Revenue for 2025 was $8.99 billion, up 7.2% from $8.38 billion in 2024, and operating income was $1.11 billion versus $1.1 billion. Net income was $774.1 million, down from $805.1 million, while operating cash flow rose to $1.56 billion from $1.19 billion. The MD&A and risk factors point to the Greif Acquisition and the restructuring of the Wallula mill as changes that will raise recycled fiber's share of the company's fiber mix. The filing also describes an amended agreement with ODP Corporation, the largest customer in the Paper segment, to supply office papers through December 31, 2026.

Hidden risk.Customer concentration is the main tension. The risk-factor text says sales to ODP represented 58% of the Paper business in 2025, and if the agreement is not renewed, ODP's purchase obligation would phase down over two years beginning January 1, 2027. Long-term debt rose from $2.47 billion in 2024 to $3.97 billion in 2025, and total assets rose from $8.83 billion to $10.73 billion. The MD&A is hard to read, with a Fog Index of 15.19, so the financing and acquisition details are easy to skim past.
