Nature of Operations and Principles of Consolidation	Description of Business The Simply Good Foods Company (“Simply Good Foods” or the “Company”), headquartered in Denver, Colorado, is a consumer packaged food and beverage company with ambitious goals to raise the bar on what food can be with trusted brands and innovative nutritious snacking products. Within our portfolio of trusted brands (Quest, Atkins, and OWYN), we offer a wide variety of nutritional snacks and beverages, including high protein chips, bars, ready-to-drink (RTD) shakes, and powders, and low sugar, low carb sweets and baked goods. We are a leader of the nutritious snacking movement, poised to expand our healthy lifestyle platform through innovation-driven organic growth and external investment opportunities. Our nutritious snacking platform consists of brands that specialize in providing products for consumers that follow certain nutritional philosophies and health-and-wellness trends: Quest for consumers seeking a variety of protein-rich foods and beverages that also limit sugars and simple carbohydrates, Atkins for those following a low-carbohydrate lifestyle or seeking to manage weight or blood sugar levels, and OWYN for consumers seeking protein-rich beverages that are plant-based and tested for the top nine allergens that also limit sugars and simple carbohydrates. We distribute our products in major retail channels, primarily in North America, including grocery, club, and mass merchandise, as well as through e-commerce, convenience, specialty, and other channels. Our portfolio of nutritious snacking brands gives us a strong platform with which to introduce new products, expand distribution, and attract new consumers to our products.
