These risks, uncertainties and contingencies are difficult to predict and beyond our control, and could cause our actual results to differ materially from those expressed or implied in such forward-looking statements.

Q1 2022 HIGHLIGHTS

Q1 2022 HIGHLIGHTS 4 341% Sales Growth (1) Q1 2022 v Q1 2021 System-Wide 16.8% SSS Growth (2) Q1 2022 v Q1 2021 System-Wide 27 New Store Openings Q1 2022 (3) $97.4mm Total Revenue Q1 2022 $15.1mm Adj. EBITDA (4) Q1 2022 $504.9mm System-Wide Sales Q1 2022 (1) System-wide sales growth reflects the percentage change in sales in any given fiscal period compared to the prior fiscal period for all stores in that brand only when the brand is owned by FAT Brands. Because of acquisitions, new store openings and store closures, the stores open throughout both fiscal periods being compared may be different from period to period. (2) Same-store sales growth reflects the change in year-over-year sales for the comparable store base, which we define as the number of stores open and in the FAT Brands system for at least one full fiscal year. For stores that were temporarily closed, sales in the current and prior period are adjusted accordingly. Given our focused marketing efforts and public excitement surrounding each opening, new stores often experience an initial start-up period with considerably higher than average sales volumes, which subsequently decrease to stabilized levels after three to six months. Additionally, when we acquire a brand, it may take several months to integrate fully each location of said brand into the FAT Brands platform. Thus, we do not include stores in the comparable base until they have been open and in the FAT Brands system for at least one full fiscal year. For 2022, the comparable store base does not include concepts acquired during fiscal 2021. (3) New store openings reflects the number of stores opened during a particular reporting period. The total number of new stores per reporting period and the timing of store openings has, and will continue to have, an impact on our results. (4) EBITDA is defined as earnings before interest, taxes, depreciation and amortization. We use the term EBITDA, as opposed to income from operations, as it is widely used by analysts, investors and other interested parties to evaluate companies in our industry. We believe that EBITDA is an appropriate measure of operating performance because it eliminates the impact of expenses that do not relate to business performance. EBITDA is not a measure of our financial performance or liquidity that is determined in accordance with generally accepted accounting principles (“GAAP”), and should not be considered as an alternative to net income (loss) as a measure of financial performance or cash flows from operations as measures of liquidity, or any other performance measure derived in accordance with GAAP. Adjusted EBITDA is defined as EBITDA (as defined above), excluding expenses related to acquisitions, refranchising gain or losses, impairment charges, and certain non-recurring or non-cash items that the Company does not believe directly reflect its core operations and may not be indicative of the Company’s recurring business operations. A reconciliation of net income presented in accordance with GAAP to EBITDA and adjusted EBITDA is set forth in the Appendix.

While we don’t include acquired concepts in same-store-sales calculation until they are owned for a full fiscal year, comparable same-store-sales including recently acquired concepts were very strong in Q1 2022 compared to Q1 2021 Q1 2022 SAME-STORE-SALES 7 (1) Same-store sales growth reflects the change in year-over-year sales for the comparable store base, which we define as the number of stores open and in the FAT Brands system for at least one full fiscal year.

APPENDIX

DEFINITIONS “EBITDA,” a non-GAAP measure, defined as earnings before interest, taxes, depreciation and amortization. We use the term EBITDA, as opposed to income from operations, as it is widely used by analysts, investors and other interested parties to evaluate companies in our industry. We believe that EBITDA is an appropriate measure of operating performance because it eliminates the impact of expenses that do not relate to business performance. EBITDA is not a measure of our financial performance or liquidity that is determined in accordance with generally accepted accounting principles (“GAAP”) and should not be considered as an alternative to net income (loss) as a measure of financial performance or cash flows from operations as measures of liquidity, or any other performance measure derived in accordance with GAAP. A reconciliation of net income presented in accordance with GAAP to EBITDA and adjusted EBITDA is set forth in the Appendix. “Adjusted EBITDA,” a non-GAAP measure, defined as EBITDA (as defined above), excluding expenses related to acquisitions, refranchising gain or losses, impairment charges, and certain non-recurring or non-cash items that the Company does not believe directly reflect its core operations and may not be indicative of the Company’s recurring business operations. A reconciliation of net income presented in accordance with GAAP to EBITDA and adjusted EBITDA is set forth in the Appendix. “Same-store sales” or “SSS” a non-GAAP measure, reflects the change in year-over-year sales for the comparable store base, which we define as the number of stores open and in the FAT Brands system for at least one full fiscal year. For stores that were temporarily closed, sales in the current and prior period are adjusted accordingly. Given our focused marketing efforts and public excitement surrounding each opening, new stores often experience an initial start-up period with considerably higher than average sales volumes, which subsequently decrease to stabilized levels after three to six months. Additionally, when we acquire a brand, it may take several months to integrate fully each location of said brand into the FAT Brands platform. Thus, we do not include stores in the comparable base until they have been open and in the FAT Brands system for at least one full fiscal year. For 2022, the comparable store base does not include concepts acquired during fiscal 2021. “System-wide sales,” a non-GAAP measure, reflects the percentage change in sales in any given fiscal period compared to the prior fiscal period for all stores in that brand only when the brand is owned by FAT Brands. Because of acquisitions, new store openings and store closures, the stores open throughout both fiscal periods being compared may be different from period to period. I
