What the franchisor excluded from this figure

- The franchisor excluded 7 franchisee-owned locations that opened during 2025 due to limited operating history.
- The franchisor excluded 14 franchisee-owned locations that were either terminated by the franchisor or reacquired by its affiliates.
This is a disclosure of what some existing outlets reported, not a projection of what a new Generator Supercenter outlet would earn. Your results will differ.
