Adjusted EBITDA Reconciliation & Key Metrics Definitions 1111 Adjusted EBITDA Reconciliation • To supplement our consolidated financial statements, which are prepared and presented in accordance with GAAP, we use the measure Adjusted EBITDA. The presentation of this financial information is not intended to be considered in isolation or as a substitute for, or superior to, the financial information prepared and presented in accordance with GAAP. • We use this non-GAAP financial measure for financial and operational decision-making and as a means to evaluate period-to-period comparisons. We believe that this non-GAAP financial measure provides meaningful supplemental information regarding our performance and liquidity by excluding certain items that may not be indicative of our recurring core business operating results. We believe that both management and investors benefit from referring to this non-GAAP financial measure in assessing our performance and when planning, forecasting, and analyzing future periods. This non-GAAP financial measure also facilitates management’s internal comparisons to our historical performance and liquidity as well as comparisons to our competitors’ operating results. We believe this non-GAAP financial measure is useful to investors both because (1) it allows for greater transparency with respect to key metrics used by management in its financial and operational decision-making and (2) it is used by our institutional investors and the analyst community to help them analyze the health of our business. • There are a number of limitations related to the use of this non-GAAP financial measure. We compensate for these limitations by providing specific information regarding the GAAP amounts excluded from this non-GAAP financial measure and evaluating this non-GAAP financial measure together with its relevant financial measures in accordance with GAAP. • A reconciliation of Adjusted EBITDA guidance is not being provided due to the nature of this forward-looking non-GAAP measure containing certain elements that are impractical to predict given their market-based nature, such as share-based compensation expense and gain and losses on change in value of warrant liabilities, without unreasonable efforts. For the same reasons, we are unable to address the probable significance of the unavailable information, nor can we accurately predict all of the components of the applicable non-GAAP financial measure and reconciling adjustments thereto; accordingly, guidance for the corresponding GAAP measure may be materially different than guidance for the non-GAAP measure. Such forward looking information is also subject to uncertainty and various risks, and there can be no assurance that any forecasted results or conditions will actually be achieved. • For more information on this non-U.S. GAAP financial measures, please see the tables captioned Reconciliation of Net Loss to Adjusted EBITDA included on slides 12-13. Key Metrics Definitions • “Systemwide Restaurant Sales” is presented as informational data in order to understand the aggregation of franchised stores sales, ghost kitchen and corporate-owned store sales performance. Systemwide Restaurant Sales growth refers to the percentage change in sales at all franchised restaurants, ghost kitchens and corporate-owned restaurants in one period from the same period in the prior year. Systemwide Restaurant Same Store Sales growth refers to the percentage change in sales at all franchised restaurants, ghost kitchens, and corporate-owned restaurants after 14 months of operations. See definition below for “Same Store Sales”. • “Corporate-Owned Restaurant Sales” represent the sales generated only by corporate-owned restaurants. Corporate-Owned Restaurant Sales growth refers to the percentage change in sales at all corporate-owned restaurants in one period from the same period in the prior year. Corporate-Owned Restaurant Same Store Sales growth refers to the percentage change in sales at all corporate-owned restaurants after 14 months of operations. These measures highlight the performance of existing corporate-owned restaurants. • “Franchise Restaurant Sales” represent the sales generated only by franchisee-owned restaurants and are not recorded as revenue, however, the royalties based on a percentage of these franchise restaurant sales are recorded as revenue. Franchise Restaurant Sales growth refers to the percentage change in sales at all franchised restaurants in one period from the same period in the prior year. Franchise Restaurant Same Store Sales growth refers to the percentage change in sales at all franchised restaurants after 14 months of operations. These measures highlight the performance of existing franchised restaurants. • “Same Store Sales” is used to evaluate the performance of our store base, which excludes the impact of new stores and closed stores, in both periods under comparison. We include a restaurant in the calculation of Same Store Sales after 14 months of operations. A restaurant which is temporarily closed (including as a result of the COVID-19 pandemic), is included in the Same Store Sales computation. A restaurant which is closed permanently, such as upon termination of the lease, or other permanent closure, is immediately removed from the Same Store Sales computation. Our calculation of Same Store Sales may not be comparable to others in the industry. • “Digital Channel” % of systemwide sales is used to measure performance of our investments made in our digital platform and partnerships with third party delivery partners. We believe our digital platform capabilities are a vital element to continuing to serve our customers and will continue to be a differentiator for the Company as compared to some of our competitors. Digital Channel as percentages of Systemwide Restaurant Sales are indicative of the sales placed through our digital platforms and the percentage of those digital sales when compared to total sales at all our franchised and corporate-owned restaurants. • “Adjusted EBITDA,” a non-GAAP measure, is defined as net loss before employee retention credits and PPP loan gain, the gain on change in value of warrant liability, income tax (benefit) expense, interest expense (which includes non-cash interest on preferred stock and interest accretion on related party notes), depreciation and amortization, share-based compensation expense, pre-opening costs, store closure costs, legal settlements, merger, acquisition and integration costs, loss (gain) on sale of assets and goodwill impairment. • Unless otherwise stated, Systemwide Restaurant Sales, Systemwide Sales growth, and Same Store Sales are presented on a systemwide basis, which means they include franchise restaurants and company-owned restaurants. Franchise restaurant sales represent sales at all franchise restaurants and are revenues to our franchisees. We do not record franchise sales as revenues; however, our royalty revenues and brand royalty revenues are calculated based on a percentage of franchise sales.
