Shake Shack Provides Fiscal Second Quarter 2026 Business Update

Management Updates Guidance

Shake Shack Inc. ("Shake Shack" or the "Company") (NYSE:SHAK) provided a business update for the fiscal second quarter ending July 1, 2026 and fiscal year ending December 30, 2026, ahead of presenting at June investor conferences.

"Our updated guidance reflects the current macroeconomic uncertainty, competitive landscape, and related impacts now that we are more than two-thirds through the quarter, but it's important to emphasize that our fundamental business drivers remain strong. We remain confident in our ability to execute our strategic priorities and deliver long-term shareholder value," said CEO Rob Lynch.

Definitions

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 (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, 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.

When used in conjunction with GAAP financial measures, the non-GAAP measures included in this press release are supplemental measures of operating performance that the Company believes are useful measures to evaluate the performance and profitability of its Shacks, and 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. The Company believes the presentation of these measures provides investors with a supplemental view of its operating performance that can provide meaningful insights to the underlying operating performance of the Company. These measures may differ from similarly titled measures used by other companies due to different methods of calculation, and presentation of these measures is not intended to be considered in isolation for, or superior to, the financial information prepared and presented in accordance with GAAP.
