CAUTIONARY NOTE ON FORWARD-LOOKING STATEMENTS & NON-GAAP MEASURES This presentation contains forward-looking statements, within the meaning of the Private Securities Litigation Reform Act of 1995 ("PSLRA"). All statements other than statements of historical fact are forward-looking statements. Forward-looking statements discuss our current expectations and projections relating to our financial position, results of operations, plans, objectives, future performance and business, and are based on currently available operating, financial and competitive information which are subject to various risks and uncertainties, so you should not place undue reliance on forward-looking statements. You can identify forward-looking statements by the fact that they do not relate strictly to historical or current facts. These statements may include words such as "aim," "anticipate," "believe," "commit," "estimate," "expect," "forecast," "outlook," "potential," "project," "projection," "plan," "intend," "seek," "may," "could," "would," "will," "should," "can," "can have," "likely," the negatives thereof and other similar expressions. Forward-looking statements are based on our current expectations and assumptions regarding our business, the economy and other future conditions. Because forward-looking statements relate to the future, by their nature, they are subject to inherent uncertainties, risks and changes in circumstances that we may not predict. As a result, our actual results may differ materially from those contemplated by the forward-looking statements, and you should not unduly rely on these statements. Important factors that could cause actual results to differ materially from those in the forward-looking statements include regional, national or global political, economic, business, competitive, market and regulatory conditions and the following: • risks related to or arising from our organizational structure; • risks of food-borne illness and food safety and other health concerns about our food; • risks relating to the economy and financial markets, including inflation, fluctuating interest rates, stock market activity, or other factors; • the impact of unionization activities of our Team Members on our reputation, operations and profitability; • risks associated with our reliance on certain information technology systems, including our new enterprise resource planning system, and potential failures or interruptions; • risks associated with data, privacy, cyber security and the use and implementation of information technology systems, including our digital ordering and payment platforms for our delivery business; • risks associated with increased adoption, implementation and use of artificial intelligence technologies across our business; • the impact of competition, including from our competitors in the restaurant industry or our own restaurants; • the increasingly competitive labor market and our ability to attract and retain the best talent and qualified employees; • the impact of federal, state or local government regulations relating to privacy, data protection, advertising and consumer protection, building and zoning requirements, labor and employment matters, costs or ability to open new restaurants, or sale of food and alcoholic beverages; • inability to achieve our growth strategy, such as the availability of suitable new restaurant sites in existing and new markets and opening of new restaurants at the anticipated rate and on the anticipated timeline; • the impact of consumer sentiment and other economic factors on our sales; • increases in food and other operating costs, tariffs and import taxes, and supply shortages; and • other risks identified in our filings with the Securities and Exchange Commission (the "SEC"). All forward-looking statements are expressly qualified in their entirety by these cautionary statements. You should evaluate all forward-looking statements made in this presentation in the context of the risks and uncertainties disclosed in the Company's most recent Annual Report on Form 10-K, filed with the SEC. All of the Company's filings are available on the SEC's website at www.sec.gov. The forward-looking statements included in this press release are made only as of the date hereof. The Company undertakes no obligation to publicly update or revise any forward-looking statement as a result of new information, future events or otherwise, except as otherwise required by law. This presentation includes certain non-GAAP measures as defined under SEC rules, including Adjusted EBITDA, Adjusted EBITDA Margin, Restaurant-Level Adjusted EBITDA and Restaurant-Level Adjusted EBITDA Margin. Reconciliations and definitions are included in the Appendix to this presentation.

FISCAL 2025 FINANCIAL TARGETS (1) We are unable to reconcile the long-term outlook for Adjusted EBITDA growth to net income (loss), the corresponding U.S. GAAP measure, due to variability and difficulty in making accurate forecasts and projections and because not all information necessary to prepare the reconciliation is available to us without unreasonable efforts. For the same reasons, we are unable to address the probable significance of the unavailable information because we cannot accurately predict all of the components of the adjusted calculations and the non-GAAP measure may be materially different than the GAAP measure.

ADJUSTED EBITDA DEFINITIONS How These Measures Are Useful We believe that Adjusted EBITDA and Adjusted EBITDA Margin are important measures of operating performance because they eliminate the impact of expenses that do not relate to our core operating performance. Adjusted EBITDA and Adjusted EBITDA Margin are supplemental measures of operating performance and our calculations thereof may not be comparable to similar measures reported by other companies. Adjusted EBITDA and Adjusted EBITDA Margin have important limitations as analytical tools and should not be considered in isolation as substitutes for analysis of our results as reported under GAAP. Adjusted EBITDA and Adjusted EBITDA Margin Adjusted EBITDA represents net income (loss) before depreciation and amortization, interest expense, interest income and income taxes, adjusted for the impact of certain non-cash and other items that we do not consider in our evaluation of ongoing core operating performance as identified in the reconciliation of net income (loss), the most directly comparable GAAP measure, to Adjusted EBITDA. Adjusted EBITDA Margin represents Adjusted EBITDA as a percentage of revenues, net. We use Adjusted EBITDA and Adjusted EBITDA Margin (i) to evaluate our operating results and the effectiveness of our business strategies, (ii) internally as benchmarks to compare our performance to that of our competitors and (iii) as factors in evaluating management’s performance when determining incentive compensation. We are unable to reconcile the long-term outlook for Adjusted EBITDA to net income (loss), the corresponding U.S. GAAP measure, due to variability and difficulty in making accurate forecasts and projections and because not all information necessary to prepare the reconciliation is available to us without unreasonable efforts. For the same reasons, we are unable to address the probable significance of the unavailable information because we cannot accurately predict all of the components of the adjusted calculations and the non-GAAP measure may be materially different than the GAAP measure.

ADJUSTED EBITDA RECONCILIATION (1) Represents the difference between cash rent payments and the recognition of straight-line rent expense recognized over the lease term. (2) Represents non-capitalized third-party consulting and software licensing costs incurred in connection with the implementation of new enterprise resource planning ("ERP") and human capital management ("HCM") systems which are included within general and administrative expenses. (3) Represents amortization of capitalized cloud-based ERP system implementation costs that are included within general and administrative expenses. (4) Represents loss on disposal of property and equipment and a technology asset impairment charge included within other income, net. (5) Represents certain expenses that management believes are not indicative of ongoing operations, consisting primarily of certain professional fees included within general and administrative expenses. (6) Represents remeasurement of the Tax Receivable Agreement liability. (7) Adjusted EBITDA Margin is defined as Adjusted EBITDA divided by Revenues, net.
