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 domestic and international licensed Shacks, as well as certain up-front fees, such as territory fees and opening fees.

"Same-Shack sales" represents Shack sales for the comparable Shack base, which is defined as the number of domestic 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.

"Shack-level operating 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.

"Shack-level operating 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 (loss) before interest expense (net of interest income), Income tax expense (benefit), and Depreciation and amortization expense.

“Adjusted EBITDA,” a non-GAAP measure, is defined as EBITDA (as defined above), excluding equity-based compensation expense, deferred lease costs, Impairment and loss on disposal of assets, 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 (loss) 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 and other items that the Company does not believe directly reflect its core operations and may not be indicative of the Company's 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 accounting principles generally accepted in the United States of America ("GAAP"), the Company uses the following non-GAAP financial measures: Shack-level operating profit, Shack-level operating profit margin, EBITDA, adjusted EBITDA, adjusted EBITDA margin, adjusted pro forma net loss and adjusted pro forma loss per fully exchanged and diluted share and adjusted pro forma effective tax rate (collectively the "non-GAAP financial measures").

Shack-Level Operating Profit

Shack-level operating 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, Shack-level operating profit and Shack-level operating 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, Shack-level operating profit and Shack-level operating 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 team member compensation as it serves as a metric in certain performance-based team member bonus arrangements. The Company believes presentation of Shack-level operating profit and Shack-level operating 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

Shack-level operating profit and Shack-level operating profit margin may differ from similarly titled measures used by other companies due to different methods of calculation. Presentation of Shack-level operating profit and Shack-level operating 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. Shack-level operating 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 Shack-level operating profit and Shack-level operating profit margin should be reviewed in conjunction with the Company's GAAP financial results. A reconciliation of Shack-level operating profit to Loss from operations, the most directly comparable GAAP financial measure, is set forth below.

NON-GAAP FINANCIAL MEASURES

(UNAUDITED)

EBITDA and Adjusted EBITDA

EBITDA is defined as Net loss before interest expense (net of interest income), Income tax expense (benefit) and Depreciation and amortization expense. Adjusted EBITDA is defined as EBITDA (as defined above) excluding equity-based compensation expense, deferred lease cost, Impairment loss on the disposal of assets, 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. A reconciliation of EBITDA and adjusted EBITDA to Net loss, the most directly comparable GAAP measure, is set forth below.

SHAKE SHACK INC.

NON-GAAP FINANCIAL MEASURES

(UNAUDITED)

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

Adjusted pro forma net loss represents Net loss 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 loss per fully exchanged and diluted share is calculated by dividing adjusted pro forma net loss 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 loss and adjusted pro forma loss 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 loss 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 loss and adjusted pro forma loss 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 loss and adjusted pro forma loss per fully exchanged and diluted share should not be considered alternatives to Net loss 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 loss attributable to Shake Shack Inc. Adjusted pro forma net loss and adjusted pro forma loss per fully exchanged and diluted share should be evaluated in conjunction with GAAP financial results. A reconciliation of adjusted pro forma net loss to Net loss attributable to Shake Shack Inc., the most directly comparable GAAP measure, and the computation of adjusted pro forma loss per fully exchanged and diluted share are set forth below.

4 TO O U R S H A R E H O L D E R S We ended the year on a strong note, with fourth quarter Average weekly sales of $76,000, with year-over- year growth driven by higher menu prices and in-Shack traffic – as more guests returned to travel, office, urban centers, and events. Shack-level operating profit margin was 18.8% in the fourth quarter, one of our highest quarterly margins in three years, despite facing high single-digit inflationary pressures in food and paper and making continued investments in our team members. We are confident that our 2023 Strategic Priorities, shared at the 25th Annual ICR Conference, are the right plan to both sustain recent momentum and ensure the long-term success of our business: 1) recruiting, rewarding and retaining a winning team, 2) relentless focus on the guest experience, led by our culinary strategy, 3) a targeted development strategy with focus on drive-thru, 4) improving Shack-level operating profit margins, and 5) investing with discipline for strong returns. Recruiting, rewarding and retaining our Team Members is our number one priority. We have not been immune to the staffing challenges in the industry, yet have seen a marked improvement in hiring over the last few months as we have doubled down on recruitment, retention and training efforts. Our culinary strategy is core to delivering a great guest experience and is just one way that we differentiate ourselves from traditional fast food. Our fourth quarter Hot Ones LTO was a success. We just launched our premium White Truffle LTO, reinforcing our elevated approach and premium ingredients. This year we plan to launch a new Veggie ShackBurger and plant-based Shake nationally, and test more ideas developed here in our Innovation Kitchen in New York City. Supply chain and permitting delays continue to impact our pace of development. We ended the year with 35 system-wide openings in the fourth quarter and plan to open approximately 65 –70 Shacks in 2023 globally across a variety of formats, including 10-15 new drive-thrus. This targeted approach to development gives us confidence that our total addressable market continues to expand. We showed strong profitability improvement in the quarter, with 240 bps year-over-year increase in our Shack-level operating profit margin. However, our work is not done. While the macro economic backdrop remains uncertain, we are investing with discipline for our growth potential, with a focus on growing sales, margins and net income as we become a much larger company.

5 AV E R A G E W E E K LY S A L E S Fourth quarter AWS was $76k with year-over-year growth led by higher menu price and in-Shack traffic growth. Our traffic benefited from more of our guests gathering and traveling, improved return to office trends and a general improvement in urban mobility. We opened 22 Company-operated Shacks in the quarter and expanded hours in many Shacks to better match the recovering mobility patterns of our guests. In October, we raised our in-Shack menu prices by mid to high single-digits, with a varied strategy of between 2% and 10% across price tiers. This was needed to help address cost pressures from high single-digit food and paper inflation and added investments in our team members. January AWS was $72k, supported by traffic and price. Traffic was strong as we lapped the impact of Omicron in the prior year and return to office factors improved in January. Omicron had the largest impact on our sales in January 2022, and our sales recovered throughout the first quarter of 2022. $72K $74K $71K $68K $76K $73K $73K $76K $77K $72K Q4 2022 AWS $76K AWS1 GROWTH WAS LED BY HIGHER MENU PRICE AND IN-SHACK TRAFFIC 48% Total YoY Shack Sales Growth Fiscal January 2023 38% Third Quarter 2021 44% Fourth Quarter 20212 17% Second Quarter 2022 18% Third Quarter 2022 16% Fiscal October 2022 31% Full Year 20213 23% First Quarter 2022 34% Fiscal December 2022 18% Fiscal November 2022 1.

Same-Shack sales grew 5.1% in the fourth quarter versus 2021, led by higher menu price and strong in- Shack performance. We raised our menu prices by mid to high single-digits in October, with a varied strategy of 2% to 10% increases across price tiers. Fourth quarter traffic declined 0.9% year-over-year. In-Shack had positive traffic in the quarter, as more guests returned to pre- COVID dining patterns. This relative strength contributed to our margin outperformance in the quarter. • Urban SSS grew 8% in the fourth quarter. Urban SSS was driven by positive price/mix and traffic growth, even as we lapped a strong 4Q2021 in urban markets. • Suburban SSS grew 3% in the fourth quarter. Suburban SSS was driven by positive price/mix and modest traffic declines year-over-year. Our suburban Shacks significantly outperformed our urban Shacks during COVID, and we are pleased to see suburban SSS continue to grow as urban markets recover. January SSS grew 17.0% versus 2022, with performance led by urban and suburban traffic and the benefit of higher menu price.

9 S H A C K - L E V E L O P E R A T I N G P R O F I T Shack-level operating profit1 of $43.2m grew 34.3% year-over-year and represents an 18.8% margin. In mid-October, we raised our menu prices by 2% to 10% across price tiers to maintain high single-digit pricing into 2023. This, in addition to strong sales performance, labor efficiencies and positive channel mix impact drove our margin performance. We plan for continued investments in our teams and expect high single-digit blended food and paper inflation to persist in the first quarter and expect mid to high single-digit inflation in FY 2023. We opened 22 new Company-operated Shacks in the fourth quarter, and 2 in FY 2023 year-to-date. Historically, our new Shacks tend to take several months to reach full operating efficiency. Our first quarter guidance reflects our expectation for modest ongoing pressure to our Shack-level operating profit margins from the large volume of fourth quarter openings still optimizing their operations through the first quarter. The components of our Shack-level costs in the fourth quarter (covered in more detail in the following pages) are as follows: • Food and paper costs were 29.5% of Shack sales. • Labor and related expenses were 28.9% of Shack sales. • Other operating expenses were 14.8% of Shack sales. • Occupancy and related expenses were 7.9% of Shack sales. 1.

Occupancy and related expenses (“Occupancy”) was 7.9% of Shack sales in the fourth quarter. Occupancy declined by 20 bps year-over-year as a percentage of Shack sales. Sales leverage was the primary driver of the year-over-year benefit. Other operating expenses (“Other opex”) was 14.8% of Shack sales in the fourth quarter, down 10 bps year-over-year.

G&A increased year-over-year primarily to support our teams and the 36 domestic Company-operated Shack openings in 2022. Depreciation and amortization expense of $19.2m increased as we opened more Shacks. Our D&A increases as we put development and other IT assets into service across our business and in our Shacks. Pre-opening expense of $6.5m was impacted by development delays. We experienced longer lead times to open restaurants, which impacts pre-opening expense. $16M $17M $18M $19M $19M 4Q21 1Q22 2Q22 3Q22 4Q22 Depreciation and Amortization Expense $5M $3M $3M $3M $6M 4Q21 1Q22 2Q22 3Q22 4Q22 Pre-opening Costs A D D I T I O N A L E X P E N S E S & A D J U S T E D E B I T D A 2.

Fiscal first quarter and fiscal year 2023 guidance is derived from preliminary, unaudited results, based on information currently available to the Company. We raised our 1Q2023 Shack sales, Licensing revenue, and SSS% guidance, lowered FY 2023 Pre- opening costs guidance, and provided additional expectations for FY 2023. While the Company believes these estimates are meaningful, they could differ from the actual results that the Company ultimately reports in its Quarterly Report on Form 10-Q for the fiscal quarter ending March 29, 2023 and its Annual Report on Form 10-K for the fiscal year ending December 27, 2023.

D E F I N I T I O N S 23 The following definitions, and definitions on the subsequent pages, apply to terms as used in this shareholder letter: "Shack sales" is defined as the aggregate sales of food, beverages, gift card breakage income, and Shake Shack branded merchandise at domestic Company-operated Shacks and excludes sales from licensed Shacks. “System-wide sales” is an operating measure and consists of sales from the Company's domestic Company-operated Shacks, domestic licensed Shacks and international 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 domestic and international licensed Shacks, as well as certain up-front fees, such as territory fees and opening fees. "Same-Shack sales" or “SSS” represents Shack sales for the comparable Shack base, which is defined as the number of domestic 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. "Average weekly sales" or “AWS” is calculated by dividing total Shack sales by the number of operating weeks for all Shacks in operation during the period. For Shacks that are not open for the entire period, fractional adjustments are made to the number of operating weeks open such that it corresponds to the period of associated sales. “Adjusted pro forma net income," a non-GAAP measure, represents Net income (loss) 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 and other items that the Company does not believe directly reflect its core operations and may not be indicative of the Company’s recurring business operations. “EBITDA,” a non-GAAP measure, is defined as Net income (loss) before interest expense (net of interest income), Income tax expense (benefit), and Depreciation and amortization expense. “Adjusted EBITDA,” a non-GAAP measure, is defined as EBITDA (as defined above), excluding equity-based compensation expense, deferred lease costs, Impairment and loss on disposal of assets, 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 EBITDA margin,” a non-GAAP measure, is defined as Net income (loss) before interest expense (net of interest income), Income tax expense (benefit) and Depreciation and amortization expense, which also excludes equity-based compensation expense, deferred lease costs, Impairment and loss on disposal of assets, 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, as a percentage of Total revenue. “Shack-level operating 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. "Shack-level operating 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.

Shack-level Operating Profit Margin Shack-level operating 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, Shack-level operating profit and Shack-level operating 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, Shack-level operating profit and Shack-level operating 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 Shack-level operating profit and Shack- level operating 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 Shack-level operating profit and Shack-level operating profit margin may differ from similarly titled measures used by other companies due to different methods of calculation. Presentation of Shack-level operating profit and Shack-level operating 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. Shack-level operating 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 Shack-level operating profit and Shack-level operating profit margin should be reviewed in conjunction with the Company’s GAAP financial results. A reconciliation of Shack-level operating profit to operating income (loss), 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 (loss) before interest expense (net of interest income), Income tax expense (benefit) and Depreciation and amortization expense. Adjusted EBITDA, a non-GAAP measure, is defined as EBITDA (as defined above) excluding equity-based compensation expense, deferred lease cost, Impairment and loss on disposal of assets, 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 EBITDA Margin Adjusted EBITDA margin, a non-GAAP measure, is defined as Net income (loss) before interest expense (net of interest income), Income tax expense (benefit) and Depreciation and amortization expense, which also excludes equity-based compensation expense, deferred lease costs, Impairment and loss on disposal of assets, 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, as a percentage of Total revenue. 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.

Adjusted Pro Forma Net Income (Loss) and Adjusted Pro Forma Earnings (Loss) Per Fully Exchanged and Diluted Share Adjusted pro forma net income (loss) represents Net income (loss) 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 (loss) per fully exchanged and diluted share is calculated by dividing adjusted pro forma net income (loss) 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 (loss) and adjusted pro forma earnings (loss) 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 (loss) 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 (loss) and adjusted pro forma earnings (loss) 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 (loss) and adjusted pro forma earnings (loss) per fully exchanged and diluted share should not be considered alternatives to Net income (loss) 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 attributable to the non-controlling interest holders and therefore does not provide a complete understanding of the Net income (loss) attributable to Shake Shack Inc. Adjusted pro forma net income (loss) and adjusted pro forma earnings (loss) per fully exchanged and diluted share should be evaluated in conjunction with GAAP financial results.

Adjusted Pro Forma Effective Tax Rate Adjusted pro forma effective tax rate represents the effective tax rate 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 its recurring business operations.
