Justice Department subpoena opens investigation into Packaging Corporation of America’s business
Key Facts
Packaging Corporation of America said in its quarterly filing dated November 5 that it had received a subpoena from a grand jury at the request of the U.S. Department of Justice’s Antitrust Division. The company said it received the subpoena in late September 2026, and that it seeks certain documents related to its business. It said it is fully cooperating with the investigation. The filing puts the company, one of North America’s largest producers of containerboard and packaging materials, under scrutiny by antitrust authorities. But it does not, by itself, accuse the company of wrongdoing.
The filing did not describe the investigation as covering the entire packaging sector, but specified that the request concerned documents related to the company’s business. The development comes in a sector that has previously faced lawsuits over containerboard prices and production capacity, but the criminal and civil proceedings are separate. An earlier filing with the Securities and Exchange Commission showed that the company and seven other producers from the United States and Canada were named as defendants in a class-action lawsuit filed on July 29, 2025. The lawsuit alleged an agreement to raise containerboard prices and restrict production capacity. Those remain allegations in a civil complaint, while the Justice Department subpoena concerns a request for documents as part of a separate investigation.
The civil complaint said the period covered by the alleged agreement began on November 1, 2020 and continues to the present, and sought damages equal to three times the losses, as well as costs. That request differs from the subpoena disclosed by the company, whose filing provides no similar details about financial claims or the investigation’s possible outcome. The company did not announce in the filing that it had been charged or that authorities had reached a final decision. Instead, its statement was limited to confirming receipt of the request and its cooperation with the investigation. This means the filing confirms the existence of an investigation and a document request, while the civil lawsuit’s allegations remain part of a separate legal proceeding.
The subpoena disclosure came as the company reported improved operating and financial results for the third quarter of 2026. Net income was $262.3 million, compared with $226.9 million in the same period of 2025, while sales rose to $2,601.7 million from $2,313.4 million. Shipments of corrugated products also increased 10.6% from the third quarter of the previous year, and containerboard production reached 1,489,000 tons. The company said net income rose 15.6% year over year to $262.3 million. These figures provide a picture of the business’s performance in the quarter before the filing, alongside the emergence of the new legal matter.
The results reflect the company’s position in the containerboard and packaging market: it describes itself as the third-largest producer in North America and says it has about 16,800 employees. The scale of its operations and the importance of its product shipments provide commercial context for the investigation, without establishing wrongdoing in themselves. The civil lawsuit concerned allegations of price increases and limits on production capacity, both of which are directly related to containerboard pricing and supply. The company’s disclosure of the investigation provided no further details about its scope or the other parties involved. These boundaries remain important in distinguishing disclosed facts from allegations in the lawsuit.
The company’s shares fell in the November 5 session, the day the filing appeared, closing at $248.8, compared with a close of $259.17 on November 4, according to EL7 data. The move shows that the disclosure coincided with a daily decline in the stock, but does not by itself establish the reason for the fall. In its fourth-quarter outlook, the company had presented a picture combining steady seasonal demand with higher maintenance costs. It said it expected strong demand for corrugated products and seasonal improvement, with total shipments expected to exceed third-quarter levels. It also expected daily shipments to be at or near the prior fourth quarter’s level, with fewer shipping days than in the third quarter.
On pricing and production, the company expected containerboard and corrugated product prices to improve as previously announced price increases continued to take effect. But it said containerboard production would decline because of maintenance downtime at three mills during the fourth quarter. This puts the outlook for the coming period between improving prices and demand on one hand, and lower production related to maintenance on the other. The quarterly filing that disclosed the subpoena did not specify a later date for a decision in the investigation or details of its next steps. The published operating outlook concerns the fourth quarter and remains tied to the company’s maintenance, pricing and shipment plans.
