Navistar builds big trucks and buses, plus the engines and parts to keep them running.
Navistar International makes the big, heavy stuff that moves goods and people around. Its biggest business is trucks — the kind that pull trailers on highways or haul concrete and garbage around a job site. Think of it as the hardware store for the people who keep America's freight moving: class four through eight trucks, plus school buses, plus the engines and parts that keep those vehicles alive. The company sells mostly to fleet owners, small trucking businesses, school districts, and dealers. It makes money three main ways: selling new trucks and buses, selling parts and service, and selling engines and components to other manufacturers.
The truck business is the biggest slice, roughly three-quarters of revenue. North America is the main market, and the company's International brand trucks compete with Freightliner, Kenworth, and Peterbilt. Buses matter too — Navistar is a major player in school buses, the yellow kind that show up every weekday morning. The parts and service business is smaller but very steady, because trucks need constant maintenance and repair. Engines round out the mix, with the company building its own power plants for its vehicles and selling them to others. That combination — new vehicle sales plus the recurring parts and service revenue — gives Navistar a somewhat more stable cash flow than a pure manufacturer would have.
The company has had a rough few decades, including accounting problems and a failed engine strategy that hurt its reputation. But in 2021, Volkswagen's truck unit, Traton, bought Navistar, taking it off the New York Stock Exchange. So today Navistar is a private subsidiary of Traton, not a standalone public company. That matters for anyone looking at the old ticker NAV — it no longer trades. The current focus is on electric trucks, including battery-powered school buses and medium-duty delivery trucks, plus integrating more deeply with Traton's global parts and engine operations. Navistar still faces the same challenges as its rivals: tight margins, cyclical demand tied to the economy, and the expensive transition to zero-emission vehicles. But being part of Traton gives it deeper pockets and a bigger global platform than it had on its own.
