Tyson Foods is a protein-focused food producer, selling raw chicken, beef, pork, and prepared foods. Chicken and beef are its two largest segments, each comprising about one-third of US sales. Prepared foods constitute roughly 20% of salesand include brands like Tyson, Jimmy Dean, Hillshire Farm, Ball Park, and Sara Lee. However, most of these are in product categories rife with competition where Tyson does not have a massive market share lead. Tyson sells some products overseas, but the international segment accounts for just 5% of total revenue. The company is an active acquirer, with more recent years' purchases focused on international and food-service markets.
