I'm surprised there are not more International Harvester/Navistar historians here. Here is the stock price history as I remember it. Might have missed some details but it is all from memory. Pre 1980: Stock Price $30-40 (about $400 adjusted for future split). Company employed 100,000+ people world wide. Agricultural business was 50%+ of the company also in construction equipment and many other businesses. Don't recall annual sales/profits. Post 1980: Company entered major decline, flirted with bankruptcy for years. Sold off Ag, Construction and other businesses by 1984. Became Navistar in about 1986, trucks, engines, USA only, about 15,000 total employees. By early '90's business problems and dilution of shares had driven stock price down into the 2's. Significant company turn around starts in late '80s. Early '90's 10 for 1 split pushes stock price into the 20's. The history after that seems pretty well known here.
