Interfor makes lumber and wood products from trees it buys and processes, then sells that wood to builders, retailers, and manufacturers around the world.
Interfor is a forest products company that turns trees into lumber. It buys logs, cuts them into boards and specialty wood products at its sawmills, and sells the result to builders, home-improvement retailers, and industrial manufacturers. If you have ever framed a wall, laid a deck, or bought a piece of dimensional lumber at a hardware store, there is a decent chance the wood passed through a mill like one of Interfor's.

The business is simple on its face: saw logs, sell lumber. But the money is anything but steady. Lumber prices swing wildly, driven by home building, repair and remodeling demand, and global trade flows. Interfor does not control the price it gets; it is a price taker. So the company's real job is to be a low-cost producer and to keep its mills running efficiently so it can survive the bad years and cash in during the good ones. That means managing log costs, mill productivity, and shipping, because wood is heavy and cheap relative to its weight. Interfor has grown largely by buying other sawmill operators. It started in British Columbia and expanded across Canada and the U.S. South — the American Southeast, where pine grows fast and mills are plentiful. That geographic spread matters: it diversifies the company's exposure to any one region's timber costs, weather, and trade rules. The U.S. South has become one of its most important production bases. Like every lumber producer, Interfor is exposed to the U.S.-Canada softwood lumber dispute, a long-running trade fight that has repeatedly imposed duties on Canadian lumber shipped south of the border, which shapes where the company chooses to build and buy mills. In recent years the company has also talked about specialty products and higher-value wood items to smooth out the commodity swings.
Because it makes a commodity, Interfor's profits are cyclical and its stock tends to rise and fall with lumber prices. When prices are high, it generates a lot of cash; when they crash, margins can vanish. That is why management focuses on debt discipline and mill upgrades rather than promising smooth growth. The company's fortunes rise and fall with the housing market and with how much lumber the world needs — a straightforward business, but a very bumpy ride.
