Non-GAAP Financial Information

This press release includes projected net revenue from operations, which has not been prepared in accordance with GAAP. BetMGM believes this presentation, which it uses for its own analysis of operations, is useful in that it reflects the true economic performance of the business. If BetMGM presented net revenue from operations in accordance with GAAP, then BetMGM would present the revenues associated with its Nevada digital and retail sports betting operations different, until such time as BetMGM is licensed as a Nevada gaming operator. Currently under GAAP, its calculation of Net Revenue would be on a basis net of operating costs, such that the GAAP reported Net Revenue would be lower than the Net Revenue reported herein, with Net Income remaining the same.
