Packaging Corporation of America’s Q3 results were met with a positive market response, reflecting robust year-on-year sales growth and solid operational execution.

Kowlzan highlighted the contribution from the Greif acquisition and noted, “We have seen exceptional performance coming out of both Massillon and Riverville mills, and the integration has helped a lot.” The company also benefited from strategic inventory management, which allowed for efficient supply to customers despite ongoing maintenance outages.
