INVESTOR PRESENTATION Third Quarter 2022 Results

2 The Company urges caution in considering its current trends and any outlook on earnings disclosed in this press release. In addition, certain matters discussed in this release may constitute forward-looking statements. These forward-looking statements, which reflect management's best judgment based on factors currently known, are intended to speak only as of the date such statements are made and involve risks, uncertainties, and other factors that may cause the actual performance of Denny’s Corporation, its subsidiaries, and underlying restaurants to be materially different from the performance indicated or implied by such statements. Words such as “expect”, “anticipate”, “believe”, “intend”, “plan”, “hope”, "will", and variations of such words and similar expressions are intended to identify such forward-looking statements. Except as may be required by law, the Company expressly disclaims any obligation to update these forward-looking statements to reflect events or circumstances after the date of this release or to reflect the occurrence of unanticipated events. Factors that could cause actual performance to differ materially from the performance indicated by these forward-looking statements include, among others: the evolving COVID-19 pandemic and related containment measures, including the potential for further operational disruption from government mandates affecting restaurants; economic, public health and political conditions that impact consumer confidence and spending, including COVID-19; commodity and labor inflation; the ability to effectively staff restaurants; the Company's ability to maintain adequate levels of liquidity for its cash needs, including debt obligations, payment of dividends, planned share repurchases and capital expenditures as well as the ability of its customers, suppliers, franchisees and lenders to access sources of liquidity to provide for their own cash needs; competitive pressures from within the restaurant industry; the Company's ability to integrate and derive the expected benefits from our acquisition of Keke's Breakfast Cafe; the level of success of the Company’s operating initiatives and advertising and promotional efforts; adverse publicity; health concerns arising from food-related pandemics, outbreaks of flu viruses or other diseases; changes in business strategy or development plans; terms and availability of capital; regional weather conditions; overall changes in the general economy (including with regard to energy costs), particularly at the retail level; political environment and geopolitical events (including acts of war and terrorism); and other factors from time to time set forth in the Company’s SEC reports and other filings, including but not limited to the discussion in Management’s Discussion and Analysis and the risks identified in Item 1A. Risk Factors contained in the Company’s Annual Report on Form 10-K for the year ended December 29, 2021 (and in the Company’s subsequent Quarterly Reports on Form 10-Q and Current Reports on Form 8-K). The presentation includes references to the Company’s non-GAAP financials measures. All such measures are designated by an asterisk (*). The Company believes that, in addition to U.S. generally accepted accounting principles (GAAP) measures, certain non-GAAP financial measures are appropriate indicators to assist in the evaluation of operating performance and liquidity on a period-to-period basis. The Company uses Adjusted EBITDA, Adjusted Free Cash Flow, Adjusted Net Income and Adjusted Net Income Per Share internally as performance measures for planning purposes, including the preparation of annual operating budgets, and for compensation purposes, including incentive compensation for certain employees. Adjusted EBITDA is also used in the calculation of financial covenant ratios in accordance with the Company’s credit facility. Adjusted Free Cash Flow is also used as a non-GAAP liquidity measure by Management to assess the Company’s ability to generate cash and plan for future operating and capital actions. Management believes that the presentation of Adjusted EBITDA, Adjusted Net Income, Adjusted Net Income Per Share and Adjusted Free Cash Flow provide useful information to investors and analysts about the Company’s operating results, financial condition or cash flows. However, each of these non-GAAP financial measures should be considered as a supplement to, not a substitute for, operating income, net income, net income per share, net cash provided by (used in) operating activities, or other financial performance and liquidity measures prepared in accordance with U.S. generally accepted accounting principles. See Appendix for non-GAAP reconciliations to the following GAAP measures: FORWARD-LOOKING STATEMENTS AND NON-GAAP FINANCIAL MEASURES $ Millions (except per share amounts) 2011 2012 2013 2014 2015 2016 2017 2018 2019 2020 2021 YTD Sep 2022 Operating Income $51.0 $56.4 $47.5 $57.3 $53.2 $47.0 $70.7 $73.6 $165.0 $6.7 $104.1 $43.0 Net Income (Loss) $112.3 $22.3 $24.6 $32.7 $36.0 $19.4 $39.6 $43.7 $117.4 ($5.1) $78.1 $61.9 Net Income (Loss) per Share $1.15 $0.23 $0.26 $0.37 $0.42 $0.25 $0.56 $0.67 $1.90 ($0.08) $1.19 $1.00 Cash Provided By (Used In): Operating Activities $59.5 $59.2 $57.0 $74.6 $83.3 $71.2 $78.3 $73.7 $43.3 ($3.1) $76.2 $25.0 Investing Activities ($7.7) ($3.5) ($16.5) ($21.3) ($32.7) ($32.7) ($27.1) ($32.0) $105.0 $4.7 $29.0 ($84.0) Financing Activities ($67.1) ($55.9) ($51.2) ($53.2) ($52.0) ($37.6) ($48.7) ($41.6) ($150.0) ($1.0) ($78.5) $32.7

The Company believes that, in addition to GAAP measures, certain other non-GAAP financial measures are appropriate indicators to assist in the evaluation of restaurant-level operating efficiency and performance of ongoing restaurant-level operations. The Company uses Restaurant-level Operating Margin, Company Restaurant Operating Margin and Franchise Operating Margin internally as performance measures for planning purposes, including the preparation of annual operating budgets, and these three non-GAAP measures are used to evaluate operating effectiveness. The Company defines Restaurant-level Operating Margin as operating income excluding the following three items: general and administrative expenses, depreciation and amortization, and operating (gains), losses and other charges, net. Restaurant-level Operating Margin is presented as a percent of total operating revenue. The Company excludes general and administrative expenses, which include primarily non-restaurant-level costs associated with support of company and franchised restaurants and other activities at their corporate office. The Company excludes depreciation and amortization expense, substantially all of which is related to company restaurant-level assets, because such expenses represent historical sunk costs which do not reflect current cash outlays for the restaurants. The Company excludes special items, included within operating (gains), losses and other charges, net, to provide investors with a clearer perspective of its ongoing operating performance and a more relevant comparison to prior period results. Restaurant-level Operating Margin is the total of Company Restaurant Operating Margin and Franchise Operating Margin. The Company defines Company Restaurant Operating Margin as company restaurant sales less costs of company restaurant sales (which include product costs, company restaurant level payroll and benefits, occupancy costs, and other operating costs including utilities, repairs and maintenance, marketing and other expenses) and presents it as a percent of company restaurant sales. The Company defines Franchise Operating Margin as franchise and license revenue (which includes franchise royalties and other non-food and beverage revenue streams such as initial franchise and other fees, advertising revenue and occupancy revenue) less costs of franchise and license revenue and presents it as a percent of franchise and license revenue. These non-GAAP financial measures provide a meaningful comparison between periods and enable investors to focus on the performance of restaurant-level operations by excluding revenues and costs unrelated to food and beverage sales in addition to corporate general and administrative expense, depreciation and amortization, and operating (gains), losses and other charges, net. However, each of these non-GAAP financial measures should be considered as a supplement to, not a substitute for, operating income, net income or other financial performance measures prepared in accordance with U.S. generally accepted accounting principles. Restaurant-level Operating Margin, Company Restaurant Operating Margin and Franchise Operating Margin do not accrue directly to the benefit of shareholders because of the aforementioned excluded items and are not indicative of the overall results for the Company.
