The Sandwich and Sub Store Franchises industry has experienced consistent growth over the five years to 2019. For instance, industry revenue grew 4.3% and 6.0% in 2015 and 2017, respectively, as consumer confidence surged in those years. Franchisees managed to maintain that momentum during the period by developing new menu options that capitalize on increasing awareness of the health risks associated with a high-fat diet. As a result, the industry has been able to thrive, despite rapidly evolving consumer preferences, which has led to the stagnation and decline of other fast food and quick-service restaurants.
