The following definitions apply to these terms as used in this release:

"Shack sales" is defined as the aggregate sales of food, beverages, gift card breakage income and Shake Shack branded merchandise at Company-operated Shacks and excludes sales from licensed Shacks.

"System-wide sales" is an operating measure and consists of sales from Company-operated Shacks and licensed Shacks. The Company does not recognize the sales from licensed Shacks as revenue. Of these amounts, revenue is limited to licensing revenue based on a percentage of sales from licensed Shacks, as well as certain up-front fees, such as territory fees, opening fees, and termination fees.

"Same-Shack sales" represents Shack sales for the comparable Shack base, which is defined as the number of Company-operated Shacks open for 24 full fiscal months or longer. For consecutive days that Shacks were temporarily closed, the comparative period was also adjusted.

"Restaurant-level profit," a non-GAAP measure, is defined as Shack sales less Shack-level operating expenses including Food and paper costs, Labor and related expenses, Other operating expenses and Occupancy and related expenses.

"Restaurant-level profit margin," a non-GAAP measure, is defined as Shack sales less Shack-level operating expenses including Food and paper costs, Labor and related expenses, Other operating expenses and Occupancy and related expenses as a percentage of Shack sales.

"EBITDA," a non-GAAP measure, is defined as Net income before interest expense (net of interest income), Income tax expense, and Depreciation and amortization expense.

"Adjusted EBITDA," a non-GAAP measure, is defined as EBITDA (as defined above), excluding equity-based compensation expense, Impairments, loss on disposal of assets, and Shack closures, amortization of cloud-based software implementation costs, as well as certain non-recurring items that the Company does not believe directly reflect its core operations and may not be indicative of the Company's recurring business operations.

"Adjusted pro forma net income," a non-GAAP measure, represents Net income attributable to Shake Shack Inc. assuming the full exchange of all outstanding SSE Holdings, LLC membership interests ("LLC Interests") for shares of Class A common stock, adjusted for certain non-recurring items that the Company does not believe are directly reflected to its core operations and may not be indicative of its recurring business operations.

**SHAKE SHACK INC.**

**NON-GAAP FINANCIAL MEASURES**

**(UNAUDITED)**

To supplement the Consolidated Financial Statements, which are prepared and presented in accordance with U.S. generally accepted accounting principles ("GAAP"), the Company uses the following non-GAAP financial measures: Restaurant-level profit, Restaurant-level profit margin, EBITDA, adjusted EBITDA, adjusted EBITDA margin, adjusted pro forma net income and adjusted pro forma earnings per fully exchanged and diluted share (collectively the "non-GAAP financial measures").

**Restaurant-Level Profit**

Restaurant-level profit is defined as Shack sales less Shack-level operating expenses including Food and paper costs, Labor and related expenses, Other operating expenses and Occupancy and related expenses.

***How This Measure Is Useful***

When used in conjunction with GAAP financial measures, Restaurant-level profit and Restaurant-level profit margin are supplemental measures of operating performance that the Company believes are useful measures to evaluate the performance and profitability of its Shacks. Additionally, Restaurant-level profit and Restaurant-level profit margin are key metrics used internally by management to develop internal budgets and forecasts, as well as assess the performance of its Shacks relative to budget and against prior periods. It is also used to evaluate employee compensation as it serves as a metric in certain performance-based employee bonus arrangements. The Company believes presentation of Restaurant-level profit and Restaurant-level profit margin provides investors with a supplemental view of its operating performance that can provide meaningful insights to the underlying operating performance of the Shacks, as these measures depict the operating results that are directly impacted by the Shacks and exclude items that may not be indicative of, or are unrelated to, the ongoing operations of the Shacks. It may also assist investors to evaluate the Company's performance relative to peers of various sizes and maturities and provides greater transparency with respect to how management evaluates the business, as well as the financial and operational decision-making.

***Limitations of the Usefulness of this Measure***

Restaurant-level profit and Restaurant-level profit margin may differ from similarly titled measures used by other companies due to different methods of calculation. Presentation of Restaurant-level profit and Restaurant-level profit margin 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. Restaurant-level profit excludes certain costs, such as General and administrative expenses and Pre-opening costs, which are considered normal, recurring cash operating expenses and are essential to support the operation and development of the Company's Shacks. Therefore, this measure may not provide a complete understanding of the Company's operating results as a whole and Restaurant-level profit and Restaurant-level profit margin should be reviewed in conjunction with the Company's GAAP financial results. A reconciliation of Restaurant-level profit to Income from Operations, the most directly comparable GAAP financial measure, is set forth below.

**(UNAUDITED)**

**EBITDA and Adjusted EBITDA**

EBITDA, a non-GAAP measure, is defined as Net income before interest expense (net of interest income), Income tax expense and Depreciation and amortization expense. Adjusted EBITDA, a non-GAAP measure, is defined as EBITDA excluding equity-based compensation expense, Impairments, loss on the disposal of assets, and Shack closures, amortization of cloud-based software implementation costs, as well as certain non-recurring items that the Company does not believe directly reflect its core operations and may not be indicative of the Company's recurring business operations.

***How These Measures Are Useful***

When used in conjunction with GAAP financial measures, EBITDA and adjusted EBITDA are supplemental measures of operating performance that the Company believes are useful measures to facilitate comparisons to historical performance and competitors' operating results. Adjusted EBITDA is a key metric used internally by management to develop internal budgets and forecasts and also serves as a metric in its performance-based equity incentive programs and certain bonus arrangements. The Company believes presentation of EBITDA and adjusted EBITDA provides investors with a supplemental view of the Company's operating performance that facilitates analysis and comparisons of its ongoing business operations because they exclude items that may not be indicative of the Company's ongoing operating performance.

***Limitations of the Usefulness of These Measures***

EBITDA and adjusted EBITDA may differ from similarly titled measures used by other companies due to different methods of calculation. Presentation of EBITDA and adjusted EBITDA 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. EBITDA and adjusted EBITDA exclude certain normal recurring expenses. Therefore, these measures may not provide a complete understanding of the Company's performance and should be reviewed in conjunction with the GAAP financial measures.

**Adjusted Pro Forma Net Income (Loss) and Adjusted Pro Forma Earnings (Loss) Per Fully Exchanged and Diluted Share**

Adjusted pro forma net income represents Net income attributable to Shake Shack Inc. assuming the full exchange of all outstanding SSE Holdings, LLC membership interests ("LLC Interests") for shares of Class A common stock, adjusted for certain non-recurring items that the Company does not believe are directly related to its core operations and may not be indicative of recurring business operations. Adjusted pro forma earnings per fully exchanged and diluted share is calculated by dividing adjusted pro forma net income by the weighted-average shares of Class A common stock outstanding, assuming the full exchange of all outstanding LLC Interests, after giving effect to the dilutive effect of outstanding equity-based awards.

***How These Measures Are Useful***

When used in conjunction with GAAP financial measures, adjusted pro forma net income and adjusted pro forma earnings per fully exchanged and diluted share are supplemental measures of operating performance that the Company believes are useful measures to evaluate performance period-over-period and relative to its competitors. By assuming the full exchange of all outstanding LLC Interests, the Company believes these measures facilitate comparisons with other companies that have different organizational and tax structures, as well as comparisons period over period because it eliminates the effect of any changes in Net income attributable to Shake Shack Inc. driven by increases in its ownership of SSE Holdings, which are unrelated to the Company's operating performance, and excludes items that are non-recurring or may not be indicative of ongoing operating performance.

***Limitations of the Usefulness of These Measures***

Adjusted pro forma net income and adjusted pro forma earnings per fully exchanged and diluted share may differ from similarly titled measures used by other companies due to different methods of calculation. Presentation of adjusted pro forma net income and adjusted pro forma earnings per fully exchanged and diluted share should not be considered alternatives to Net income and earnings (loss) per share, as determined under GAAP. While these measures are useful in evaluating the Company's performance, it does not account for the earnings (loss) attributable to the non-controlling interest holders and therefore does not provide a complete understanding of the Net income attributable to Shake Shack Inc. Adjusted pro forma net income and adjusted pro forma earnings per fully exchanged and diluted share should be evaluated in conjunction with GAAP financial results. A reconciliation of adjusted pro forma net income to Net income attributable to Shake Shack Inc., the most directly comparable GAAP measure, and the computation of adjusted pro forma earnings per fully exchanged and diluted share are set forth below.

5 TO OUR SHAREHOLDERS We are proud of the work that our teams did to deliver solid fourth quarter results, while continuing to build the foundation for sustainable, long-term growth. In the fourth quarter 2025, Total revenue reached $400.5 million, up nearly 22% year-over-year, with Shack sales growing approximately 22% year-over-year to $385.3 million and Licensing revenue reaching $15.2 million, along with 23% year-over-year growth in System-wide sales. We grew same-Shack sales 2.1% - marking the 20th consecutive quarter of positive growth for our Company. We delivered 0.5% positive traffic growth and 1.6% price/mix. Same-Shack sales grew sequentially each month of the quarter, however the last six weeks of the quarter did not meet our expectations due to inclement weather in some of our most heavily penetrated markets like the Northeast. D spite weather-related headwinds, we maintained positive same-Shack sales and positive traffic. With our strong sales and operational improvements, we sustained our Restaurant-level profit margin at 22.7% - demonstrating our ability to maintain profitability despite macroeconomic headwinds and higher beef costs that rose by low-teens. We continue to strengthen our culinary development process through our disciplined stage-ga e framework, ensuring every item meets our gold standard of culinary innovation and quality, resonates with our guests, and is operationally friendly. Our enhanced approach delivered tangible results throughout the year, including one of our most successful LTO shakes, the Dubai Chocolate Shake, and successful side innovations like onion rings, which resonated so strongly with guests the item was added to our core menu. Building a strong culture of leaders remains essential to how we open our pipeline with excellence and execute against our long-term growth objectives. We opened 15 new Company-operated Shacks and 17 new licensed Shacks in the fourth quarter. For the full year 2025, we opened 45 Company-operated Shacks - our largest class to date - and 40 licensed Shacks. We made significant progress in optimizing our build model, reducing the average net build cost for new Shacks to under $2 million in 2025, a reduction of approximately 20% compared to the prior year. In 2025, we grew Total revenue by more than 15% to $1.45 billion, delivered positive same-Shack sales growth of 2.3%, expanded our Restaurant-level profit margin by 120 basis points to 22.6%, and drove 20% year-over-year growth in Adjusted EBITDA, reaching approximately $210 million. Looking ahead to 2026, we are building off our strong 2025 foundation with clear strategic priorities and disciplined execution. We plan to open 55 to 60 new Company-operated Shacks, primarily in markets outside of our historical footprint. We remain focused on becoming a best-in-class restaurant operations company, supporting our team members to accurately and expediently serve guests the highest-quality food in the industry at great value with enlightened hospitality.

RESTAURANT -LEVEL PROFIT DEFINITIONS 22 Restaurant -Level Profit "Restaurant-level profit," a non-GAAP measure, is defined as Shack sales less Shack-level operating expenses, including Food and paper costs, Labor and related expenses, Other operating expenses, and Occupancy and related expenses. Restaurant -level Profit Margin "Restaurant-level profit margin," a non-GAAP measure, is defined as Shack sales less Shack-level operating expenses, including Food and paper costs, Labor and related expenses, Other operating expenses and Occupancy and related expenses as a percentage of Shack sales. How This Measure Is Useful When used in conjunction with GAAP financial measures, Restaurant-level profit and Restaurant-level profit margin are supplemental measures of operating performance that the Company believes are useful measures to evaluate the performance and profitability of its Shacks. Additionally, Restaurant-level profit and Restaurant-level profit margin are key metrics used interally by management to develop internal budgets and forecasts, as well as assess the performance of its Shacks relative to budget and against prior periods. It is also used to evaluate employee compensation as it serves as a metric in certain performance-based employee bonus arrangements. The Company believes presentation of Restaurant-level profit and Restaurant-level profit margin provides investors with a supplemental view of its operating performance that can provide meaningful insights to the underlying operating performance of the Shacks, as these measures depict the operating results that are directly impacted by the Shacks and exclude items that may not be indicative of, or are unrelated to, the ongoing operations of the Shacks. It may also assist investors to evaluate the Company's performance relative to peers of various sizes and maturities and provides greater transparency with respect to how management evaluates the business, as well as the financial and operational decision-maki g. Limitations of the Usefulness of this Measure Restaurant-level profit and Restaurant-level profit margin may differ from similarly titled measures used by other companies due to different methods of calculation. Presentation of Restaurant-level profit and Restaurant-level profit margin 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. Restaurant-level profit excludes certain costs, such as General and administrative expenses and Pre-opening costs, which are considered normal, recurring cash operating expenses and are essential to support the operation and development of the Company's Shacks. Therefore, this measure may not provide a complete understanding of the Company's operating results as a whole and Restaurant-level profit and Restaurant-level profit margin should be reviewed in conjunction with the Company's GAAP financial results. A reconciliation of Restaurant-level profit to operating income, the most directly comparable GAAP financial measure, is set forth on next slide.

EBITDA and Adjusted EBITDA EBITDA, a non-GAAP measure, is defined as Net income before interest expense (net of interest income), Income tax expense and Depreciation and amortization expense. Adjusted EBITDA, a non-GAAP measure, is defined as EBITDA (as defined above) excluding equity-based compensation expense, Impairments, loss on disposal of assets and Shack closures, amortization of cloud- based software implementation costs, as well as certain non-recurring items that the Company does not believe directly reflect its core operations and may not be indicative of the Company's recurring business operations. How These Measures Are Useful When used in conjunction with GAAP financial measures, EBITDA and adjusted EBITDA are supplemental measures of operating performance that the Company believes are useful measures to facilitate comparisons to historical performance and competitors' operating results. Adjusted EBITDA is a key metric used internally by management to develop internal budgets and forecasts and also serves as a metric in its performance-based equity incentive programs and certain bonus arrangements. The Company believes presentation of EBITDA and adjusted EBITDA provides investors with a supplemental view of the Company's operating performance that facilitates analysis and comparisons of its ongoing business operations because they exclude items that may not be indicative of the Company's ongoing operating performance. Limitations of the Usefulness of These Measures EBITDA and adjusted EBITDA may differ from similarly titled measures used by other companies due to different methods of calculation. Presentation of EBITDA and adjusted EBITDA 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. EBITDA and adjusted EBITDA exclude certain normal recurring expenses. Therefore, these measures may not provide a complete understanding of the Company's performance and should be reviewed in conjunction with the GAAP financial measures.

Adjusted Pro Forma Net Income and Adjusted Pro Forma Earnings Per Fully Exchanged and Diluted Share Adjusted pro forma net income represents Net income attributable to Shake Shack Inc. assuming the full exchange of all outstanding SSE Holdings, LLC membership interests ("LLC Interests") for shares of Class A common stock, adjusted for certain non- recurring items that the Company does not believe are directly related to its core operations and may not be indicative of recurring business operations. Adjusted pro forma earnings per fully exchanged and diluted share is calculated by dividing adjusted pro forma net income by the weighted-average shares of Class A common stock outstanding, assuming the full exchange of all outstanding LLC Interests, after giving effect to the dilutive effect of outstanding equity-based awards. How These Measures Are Useful When used in conjunction with GAAP financial measures, adjusted pro forma net income and adjusted pro forma earnings per fully exchanged and diluted share are supplemental measures of operating performance that the Company believes are useful measures to evaluate performance period over period and relative to its competitors. By assuming the full exchange of all outstanding LLC Interests, the Company believes these measures facilitate comparisons with other companies that have different organizational and tax structures, as well as comparisons period over period because it eliminates the effect of any changes in Net income attributable to Shake Shack Inc. driven by increases in its ownership of SSE Holdings, which are unrelated to the Company's operating performance, and excludes items that are non-recurring or may not be indicative of ongoing operating performance. Limitations of the Usefulness of These Measures Adjusted pro forma net income and adjusted pro forma earnings per fully exchanged and diluted share may differ from similarly titled measures used by other companies due to different methods of calculation. Presentation of adjusted pro forma net income and adjusted pro forma earnings per fully exchanged and diluted share should not be considered alternatives to Net income and earnings per share, as determined under GAAP. While these measures are useful in evaluating the Company's performance, it does not account for the earnings attributable to the non-controlling interest holders and therefore does not provide a complete understanding of the Net income attributable to Shake Shack Inc. Adjusted pro forma net income and adjusted pro forma earnings per fully exchanged and diluted share should be evaluated in conjunction with GAAP financial results.
