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 sales and 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.
