SHAKE SHACK INC.

NON-GAAP FINANCIAL MEASURES

(UNAUDITED)

To supplement the condensed 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.

Exhibit 99.1

A reconciliation of Restaurant-level profit to Income from Operations, the most directly comparable GAAP financial measure, is set forth below.

NON-GAAP FINANCIAL MEASURES

(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 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.
