Enter a ticker to learn what the company does and how it makes money.
It makes cardboard boxes and the paper that goes into them.
Packaging Corporation of America makes the boring stuff that makes modern life possible: corrugated cardboard boxes. If you have ever ordered something online and it arrived in a brown box, there is a decent chance that box started as a sheet of paper made by this company. It sells to businesses, not consumers. Its customers are companies that need to ship stuff — food and beverage makers, e-commerce retailers, manufacturers, and pretty much anyone who moves physical goods from one place to another. The company is headquartered in Lake Forest, Illinois, just north of Chicago.
The business has two main pieces: packaging and paper. Packaging is the big one — roughly 85 to 90 percent of revenue — and it is exactly what it sounds like. The company runs mills that turn wood into paper, then turns that paper into corrugated boxes and other protective packaging. The paper segment is smaller and mostly sells containerboard and other paper products to outside buyers. Think of it as a tree-to-doorstep operation: cut trees, make paper, fold it into boxes, ship the boxes to customers who then ship their own products in them. It is a vertically integrated business, meaning PCA controls most of the steps from raw material to finished box, which helps keep costs down and quality consistent.
The company is not a flashy growth story. It is a steady, cash-generative industrial business. Demand for boxes tracks the health of the economy — more shipping means more boxes. In recent years, PCA has invested heavily in modernizing its mills and expanding capacity, and it has been a reliable dividend payer and share repurchaser. It does not need to reinvent itself every few years. It just needs to keep making boxes efficiently and keep its customers happy. That simplicity is part of its appeal: a business that makes an essential product, controls its own supply chain, and returns cash to shareholders.
