Q3 2025 EARNINGS SUPPLEMENT NOVEMBER 5, 2025

LEGAL DISCLAIMER This earnings supplement contains forward-looking statements within the meaning of the Private Securities Litigation Reform Act of 1995, including statements relating to the future financial and operating results of the Company, estimates of future EBITDA, the timing and performance of new store openings, future reductions in cost of capital and leverage ratio, our ability to conduct future accretive acquisitions and our pipeline of new store locations. Forward-looking statements generally use words such as “expect,” “foresee,” “anticipate,” “believe,” “project,” “should,” “estimate,” “will,” “plans,” “forecast,” and similar expressions, and reflect our expectations concerning the future. Forward-looking statements are subject to significant business, economic and competitive risks, uncertainties and contingencies, many of which are difficult to predict and beyond our control, which could cause our actual results to differ materially from the results expressed or implied in such forward-looking statements. We refer you to the documents that we file from time to time with the Securities and Exchange Commission, such as our reports on Form 10-K, Form 10-Q and Form 8-K, for a discussion of these and other risks and uncertainties that could cause our actual results to differ materially from our current expectations and from the forward- looking statements contained in this earnings supplement. We undertake no obligation to update any forward-looking statements to reflect events or circumstances occurring after the date of this earnings supplement. 2

Q3 2025 HIGHLIGHTS 3 -5.5% Sales Decline (1) System-Wide -3.5% SSS Decline (2) System-Wide 13 New Store Openings (3) Q3 2025 $140.0mm Total Revenue Q3 2025 $13.1mm Adj. EBITDA (4) Q3 2025 $567.5mm System-Wide Sales (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. (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.

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. “Adjusted net loss,” a non-GAAP measure, defined as net loss plus the impact of adjustments and the tax effects of such adjustments. Adjusted net loss is presented because we believe it helps convey supplemental information to investors regarding our performance, excluding the impact of special items that affect the comparability of results in past quarters to expected results in future quarters. Adjusted net loss as presented may not be comparable to other similarly titled measures of other companies, and our presentation of adjusted net loss should not be construed as an inference that our future results will be unaffected by excluded or unusual items. Our management uses this non- GAAP financial measure to analyze changes in our underlying business from quarter to quarter based on comparable financial results. Reconciliations of net loss attributable to FAT Brands Inc. presented in accordance with GAAP to EBITDA, adjusted EBITDA and adjusted net loss are set forth in the Appendix. “Same-store sales growth” 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. “System-wide sales growth,” 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
