Accounting Policies [Abstract]
SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES	SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES Basis of Presentation The accompanying Consolidated Financial Statements have been prepared in accordance with accounting principles generally accepted in the United States of America ("GAAP") and include the accounts of Shake Shack Inc. and its subsidiaries. All intercompany accounts and transactions have been eliminated in consolidation. Certain reclassifications have been made to prior period amounts to conform to the current year presentation. SSE Holdings is considered a variable interest entity. Shake Shack Inc. is the primary beneficiary as the Company has the majority economic interest in SSE Holdings and, as the sole managing member, has decision making authority that significantly affects the economic performance of the entity, while the limited partners have no substantive kick-out or participating rights. As a result, the Company consolidates SSE Holdings. The assets and liabilities of SSE Holdings represent substantially all of the Company's consolidated assets and liabilities with the exception of certain deferred taxes and liabilities under the Tax Receivable Agreement. As of December 25, 2024 and December 27, 2023, the net assets of SSE Holdings were $413,793 and $388,250, respectively. The assets of SSE Holdings are subject to certain restrictions in SSE Holdings' revolving credit agreement. Refer to Note 8, Debt, and Note 14, Income Taxes, for additional information. Fiscal Year The Company operates on a 52/53 week fiscal year ending on the last Wednesday of December. Fiscal 2024 contained 52 weeks and ended on December 25, 2024 ("fiscal 2024"). Fiscal 2023 contained 52 weeks and ended on December 27, 2023 ("fiscal 2023"). Fiscal 2022 contained 52 weeks and ended on December 28, 2022 ("fiscal 2022"). Unless otherwise stated, references to years in this report relate to fiscal years. Use of Estimates The preparation of these Consolidated Financial Statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements, and the reported amounts of sales and expenses during the reporting period. Actual results could differ from those estimates. Fair Value Measurements The Company applies fair value accounting for all financial assets and liabilities and non-financial assets and liabilities that are recognized or disclosed at fair value in the financial statements on a recurring basis. Assets and liabilities are categorized based on the priority of the inputs to the valuation technique into a three-level fair value hierarchy as set forth below. ▪ Level 1 — Quoted prices in active markets for identical assets or liabilities. ▪ Level 2 — Observable inputs other than quoted prices in active markets for identical assets or liabilities, quoted prices for identical assets or liabilities in inactive markets, or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the asset or liability. ▪ Level 3 — Inputs that are both unobservable and significant to the overall fair value measurements reflecting an entity's estimates of assumptions that market participants would use in pricing the asset or liability. Cash and Cash Equivalents Cash and cash equivalents consist primarily of cash on hand, deposits with banks, money market funds and short-term, highly liquid investments that have original maturities of three months or less. Cash equivalents are stated at cost, which approximates fair value. Marketable Securities Marketable securities classified as held-to-maturity securities consist of U.S. Treasuries for which the Company has the ability and intent to hold to maturity and are reported at amortized cost, net of a valuation allowance for credit losses. Interest income and the amortization of discounts and premiums are recorded in Other income, net on the Consolidated Statements of Income (Loss). No expected credit losses were recognized as of December 25, 2024 and December 27, 2023. Accounts Receivable, Net Accounts receivable, net consist primarily of receivables from our licensees for licensing revenue and related reimbursements, credit card receivables and vendor rebates. The collectability of accounts receivable is evaluated based on a variety of factors, including historical experience, current economic conditions and other factors. Inventories Inventories, which consist of food, paper goods, beverages, beer, wine and retail merchandise, are valued at the lower of weighted average cost or net realizable value. No adjustment is deemed necessary to reduce inventory to net realizable value due to the rapid turnover and high utilization of inventory. Property and Equipment, Net Property and equipment, net is stated at historical cost less accumulated depreciation. Property and equipment are depreciated using the straight-line method over the estimated useful lives of the assets, which generally range from five two Costs incurred when constructing Shacks are capitalized. The cost of repairs and maintenance are expensed when incurred. Costs for refurbishments and improvements that significantly increase the productive capacity or extend the useful life of the assets are capitalized. When assets are disposed, the resulting gain or loss is recognized in Impairments, loss on disposal of assets, and Shack closures on the Consolidated Statements of Income (Loss). Valuation of Long-lived Assets The Company assesses potential impairments to its long-lived assets, which include property and equipment and operating and finance lease right-of-use assets, whenever events or circumstances indicate that the carrying value of an asset may not be recoverable. The recoverability evaluation is first performed at the market service area level ("MSA"). If the carrying value of the MSA exceeds its estimated undiscounted future cash flows, a secondary recoverability test is performed for all individual Shacks within the identified MSA. An impairment charge is recognized when the carrying amount of the asset exceeds the fair value of the asset, considering external market participant assumptions, and is allocated across all assets of the impaired Shack. Since the determination of future cash flows is an estimate of future performance, there may be future impairments in the event that future cash flows do not meet expectations. Refer to Note 4, Fair Value Measurements, for additional information. Deferred Financing Costs Deferred financing costs incurred in connection with the issuance of long-term debt and establishing credit facilities are capitalized and amortized in Interest expense on the Consolidated Statements of Income (Loss) based on the related debt agreements. Deferred financing costs are included in Other assets on the Consolidated Balance Sheets. Other Assets Other assets consist primarily of capitalized implementation costs from cloud computing arrangements, certain custom pre-ordered furniture, fixtures and equipment for future and existing Shacks, transferable liquor licenses, and security deposits. Implementation costs associated with cloud computing arrangements hosted by third-party vendors are capitalized when incurred during the application development phase. Amortization is calculated on a straight-line basis over the contractual term of the cloud computing arrangement and is recorded within General and administrative expenses on the Consolidated Statements of Income (Loss). As of December 25, 2024 and December 27, 2023, capitalized implementation costs from cloud computing arrangements totaled $4,051 and $5,572, respectively, net of accumulated amortization. The costs of obtaining non-transferable liquor licenses that are directly issued by local government agencies for nominal fees are expensed as incurred. The costs of purchasing transferable liquor licenses through open markets in jurisdictions with a limited number of authorized liquor licenses are capitalized as indefinite-lived intangible assets. Annual liquor license renewal fees, for both types of licenses, are expensed over the renewal term. As of December 25, 2024 and December 27, 2023, indefinite-lived intangible assets relating to transferable liquor licenses totaled $2,040 and $1,903, respectively. Indefinite-lived intangible assets are evaluated for impairment at least annually during the fourth quarter, and whenever events or circumstances indicate that an impairment may exist. When evaluating intangible assets for impairment, the Company first performs a qualitative assessment to determine whether it is more likely than not that an intangible asset group is impaired. If determined that it is more likely than not that the carrying value of the intangible asset group exceeds its fair value, the Company performs a quantitative assessment to derive the fair value of the intangible asset group. If the carrying value of the intangible asset group exceeds the estimated fair value, an impairment charge is recorded to reduce the carrying value to the estimated fair value. In addition, the Company continuously monitors and may revise the useful lives of intangible assets when facts and circumstances change. Revenue Recognition Shack Sales Revenue from Shack sales is recognized when payment is tendered at the point of sale, net of discounts, as the performance obligation has been satisfied at that time. Sales tax collected from guests is excluded from Shack sales and the obligation is included in Other current liabilities on the Consolidated Balance Sheets until the taxes are remitted to the appropriate taxing authorities. Delivery services are fulfilled by third-party delivery partners whether ordered through the Shack app, website (collectively, "Company-owned platforms") or through third-party delivery platforms. Revenue from orders through Company-owned platforms includes delivery fees and is recognized when the delivery partner transfers the order to the guest as the Company controls the delivery. For these sales, the Company receives payment directly from the guest at the time of sale. Revenue from orders through third-party delivery platforms is recognized when the order is transferred to the third-party delivery partner and excludes delivery fees collected by the delivery partner as the Company does not control the delivery. The Company receives payment from the delivery partner subsequent to the transfer of the order and the payment terms are short-term in nature. For all delivery sales, the Company is considered the principal and recognizes revenue on a gross basis. The Company sells gift cards which do not have expiration dates. Revenue from gift cards is recognized when gift cards are redeemed by the guest or, in the event a gift card is not expected to be redeemed, in proportion to actual redemptions of gift cards ("gift card breakage"). The gift card breakage rate is determined from historical gift card redemption patterns. Gift card breakage income for fiscal 2024, 2023, and 2022 was $413, $327 and $1,472, respectively. During fiscal 2022, the Company concluded it had accumulated a sufficient level of historical data from a large pool of homogeneous transactions to allow it to reasonably and objectively determine an estimated gift card breakage rate and the pattern of actual gift card redemptions. In accordance with ASC 250, Accounting Changes and Error Corrections, the Company concluded that this accounting change represented a change in accounting estimate. As a result, a cumulative catch-up adjustment was recorded during fiscal 2022 that resulted in $1,281 of gift card breakage income. Gift card breakage income is included in Shack sales on the Consolidated Statements of Income (Loss). Licensing Revenue Licensing revenue includes initial territory fees, Shack opening fees and ongoing sales-based royalty fees from licensed Shacks. Generally, the licenses granted to develop, open and operate each Shack in a specified territory are the predominant good or service transferred to the licensee and represent distinct performance obligations. Ancillary promised services, such as training and assistance during the initial opening of a Shack, are typically combined with the license and considered one performance obligation per Shack. The Company determines the transaction price for each contract, which requires judgment as the transaction price is comprised of the initial territory fee and an estimate of the total Shack opening fees based on the estimated number of Shacks the Company expects the licensee to open. The transaction price is then allocated equally to each Shack expected to open. The performance obligation is satisfied over time, starting when a Shack opens through the end of the license term for the related Shack, therefore revenue is recognized on a straight-line basis over the license term. Generally, payment for the initial territory fee is received upon execution of the license agreement and payment for the Shack opening fees is received either in advance of or upon opening the related Shack. These payments are initially deferred and recognized in revenue as the performance obligations are satisfied. Revenue from sales-based royalties is recognized as the related sales occur. Equity-based Compensation Equity-based compensation expense is measured based on the grant-date fair value of the awards. For awards with graded-vesting features and service conditions only, compensation expense is recognized on a straight-line basis over the total requisite service period for the entire award. For awards with graded-vesting features and a combination of service and performance conditions, compensation expense is recognized using a graded-vesting attribution method over the vesting period based on the most probable outcome of the performance conditions. For awards with cliff vesting features and a combination of service and performance conditions, compensation expense is recognized on a straight-line basis over the total requisite service period for the entire award based on the most probable outcome of the performance conditions. For awards that contain a market condition, a Monte Carlo simulation valuation model is used to calculate the grant-date fair value. The assumptions used in the valuation include expected term, volatility, risk-free interest rate, and closing price as of the valuation date. Compensation expense for awards containing a market condition is recognized ratably over the performance period regardless of whether the market condition and requisite service period are met. Actual distributed shares are calculated upon conclusion of the service and performance periods. Forfeitures are recognized as they occur for all equity awards. Equity-based compensation expense is included in General and administrative expenses and Labor and related expenses on the Consolidated Statements of Income (Loss). Advertising Most advertising costs are expensed as incurred, with the exception of advertising production costs, which are expensed at the time the advertising first takes place. Advertising costs totaled $22,169, $12,437 and $12,376 in fiscal 2024, fiscal 2023 and fiscal 2022, respectively, and are included in General and administrative expense and Other operating expenses on the Consolidated Statements of Income (Loss). Leases Shake Shack currently leases all of its Company-operated Shacks, the home office and certain equipment under various non-cancelable lease agreements that expire on various dates through 2045. The Company evaluates contracts entered into to determine whether the contract involves the use of property or equipment, which is either explicitly or implicitly identified in the contract. The Company evaluates whether it controls the use of the asset, which is determined by assessing whether substantially all economic benefit from the use of the asset is obtained, and whether the Company has the right to direct the use of the asset. If these criteria are met, the Company has identified a lease, within the contract, and therefore a right of use asset and lease liability are recorded on the Consolidated Balance Sheets. Upon possession of a leased asset, the Company determines whether the lease is an operating or finance lease. All of the Company's real estate leases are classified as operating leases and most equipment leases are classified as finance leases. Generally, real estate leases have initial terms ranging from 10 to 15 years and typically include two five-year renewal options. Renewal options are generally not recognized as part of the right-of-use assets and lease liabilities as it is not reasonably certain at commencement date that the Company would exercise the renewal options. Real estate leases typically contain fixed minimum rent payments and/or contingent rent payments which are based upon sales in excess of specified thresholds. When the achievement of such sales thresholds are deemed to be probable, contingent rent is accrued in proportion to the sales recognized during the period. For operating leases, fixed lease payments are recognized as operating lease costs on a straight-line basis over the lease term and are reported in specific line items on the Consolidated Statements of Income (Loss). Lease expense incurred before a Shack opens is recorded in Pre-opening costs. Once a Company-operated Shack opens, the straight-line lease expense and contingent rent, if applicable, are recorded in Occupancy and related expenses. Many of these leases also require the Company to pay real estate taxes, common area maintenance costs and other occupancy costs which are included in Occupancy and related expenses. Finance leases are recognized in depreciation expense on a straight-line basis over the remaining lease term, along with recognition of interest expense associated with accretion of the lease liability. For both operating and finance leases that contain lease and non-lease components, the components are combined and accounted for as a single lease component. Variable lease costs for both operating and finance leases, if any, are recognized as incurred. Leases with a term of 12 months or less are deemed short-term and are not recognized on the Consolidated Balance Sheets. Fixed lease payments for short-term leases are recognized on a straight-line basis over the lease term. The Company calculates operating lease right-of-use assets and lease liabilities as the present value of fixed lease payments over the reasonably certain lease term beginning at the commencement date. The Company uses its incremental borrowing rate (“IBR”) in determining the present value of future lease payments as there are no explicit rates provided in the leases. The IBR used to measure the lease liability is derived from the average of the yield curves obtained from using the notching method and the recovery rate method. The most significant assumption in calculating the IBR is the Company's credit rating and is subject to judgment. The credit rating used to develop the IBR is determined by utilizing the credit ratings of other public companies with similar financial information as SSE Holdings. The Company expends cash for leasehold improvements to build out and equip leased properties. Generally, a portion of the leasehold improvements and building costs are reimbursed by the landlords through landlord incentives pursuant to agreed-upon terms in the lease agreements. Landlord incentives usually take the form of cash, full or partial credits against future minimum or contingent rents otherwise payable by the Company, or a combination thereof. In most cases, landlord incentives are received after the Company takes possession of the property and as milestones are met during the construction of the property. The Company includes these amounts in the measurement of the initial operating lease liability and right-of-use asset. Pre-opening Costs Pre-opening costs are expensed as incurred and consist primarily of occupancy, manager and team member wages, cookware, travel and lodging costs for the opening training team and other supporting team members, marketing expenses, legal fees, and inventory costs incurred prior to the opening of a Shack. Income Taxes Income taxes are accounted for pursuant to the asset and liability method which requires the recognition of deferred income tax assets and liabilities related to the expected future tax consequences arising from temporary differences between the carrying values and tax bases of assets and liabilities based on enacted statutory tax rates applicable to the periods in which the temporary differences are expected to reverse. Any effects of changes in income tax rates or laws are included in Income tax expense on the Consolidated Statements of Income (Loss) in the period of enactment. A valuation allowance is recognized if we determine it is more likely than not that all or a portion of a deferred tax asset will not be recognized. In making such determination, the Company considers all available evidence, including scheduled reversals of deferred tax liabilities, projected future taxable income, tax planning strategies, and recent and expected future results of operations.

The Company performs its impairment analysis at least annually or whenever events or circumstances indicate that the carrying amount of an asset may not be recoverable. During fiscal 2024, the Company determined to close and executed the closure of nine underperforming Company-operated Shacks in California, Ohio and Texas as these Shacks were not projected to provide acceptable returns in the foreseeable future, in part due to changes in the trade area and the negative impact on other Shacks within their proximity by cannibalizing sales. The total expenses related to the identified Shack closures were $29,348, of which $27,633 was impairment expense, related to right-of-use assets, and property, plant and equipment, and $1,715 was miscellaneous Shack closure expense. The fair values of assets were determined using an income-based approach and are classified as Level 3 within the fair value hierarchy. Significant inputs include projections of future cash flows, Shack sales, profitability, discount rates, and sublease income.

Debt Disclosure [Abstract]
DEBT	DEBT Convertible Notes The Company's $250,000 aggregate principal amount of 0% Convertible Senior Notes due 2028 (“Convertible Notes”) will mature on March 1, 2028, unless earlier converted, redeemed or repurchased in certain circumstances. Upon conversion, the Company pays or delivers, as the case may be, cash, shares of Class A common stock or a combination of cash and shares of Class A common stock, at the Company's election. The Convertible Notes are convertible at the option of the holders at any time prior to the close of business on the business day immediately preceding December 1, 2027, only under the following circumstances: (1) during any fiscal quarter commencing after the fiscal quarter ending on June 30, 2021 (and only during such fiscal quarter), if the last reported sale price of the Company's Class A common stock, par value $0.001 per share, for at least 20 trading days (whether or not consecutive) during a period of 30 consecutive trading days ending on, and including, the last trading day of the immediately preceding fiscal quarter is greater than or equal to 130% of the conversion price for the Convertible Notes on each applicable trading day; (2) during the five business day period after any 10 consecutive trading day period (the “measurement period”) in which the trading price (as defined in the Indenture) per one thousand dollar principal amount of the Convertible Notes for each trading day of the measurement period was less than 98% of the product of the last reported sale price of Class A common stock and the conversion rate for the Convertible Notes on each such trading day; (3) if the Company calls such Convertible Notes for redemption, at any time prior to the close of business on the scheduled trading day immediately preceding the redemption date, but only with respect to the Convertible Notes called (or deemed called) for redemption; and (4) upon the occurrence of specified corporate events as set forth in the Indenture. On or after December 1, 2027, until the close of business on the second scheduled trading day immediately preceding the maturity date, holders of the Convertible Notes may convert all or any portion of their Convertible Notes at any time, regardless of the foregoing circumstances. The Convertible Notes had an initial conversion rate of 5.8679 shares of Class A common stock per one thousand dollar principal amount of Convertible Notes, which is equivalent to an initial conversion price of approximately $170.42 per share of Class A common stock. The fair value of the Convertible Notes was approximately $256,900 and $205,000, respectively, as of December 25, 2024 and December 27, 2023, based on external pricing data, including available quoted market prices of these instruments, and consideration of comparable debt instruments with similar interest rates and trading frequency, among other factors, and is classified as a Level 2 measurement within the fair value hierarchy. The Company may not redeem the Convertible Notes prior to March 6, 2025. The Company may redeem for cash all or any portion of the Convertible Notes, at the Company's option, on or after March 6, 2025 if the last reported sale price of Class A common stock has been at least 130% of the conversion price then in effect for at least 20 trading days (whether or not consecutive) during any 30 consecutive trading day period (including the last trading day of such period) ending on, and including, the trading day immediately preceding the date on which the Company provides notice of redemption at a redemption price equal to 100% of the principal amount of the Convertible Notes to be redeemed, plus accrued and unpaid special interest, if any, to, but excluding, the redemption date. In addition, if Shake Shack undergoes a fundamental change (as defined in the indenture governing the Convertible Notes), subject to certain conditions, holders may require it to repurchase for cash all or any portion of their Convertible Notes at a repurchase price equal to 100% of the principal amount of the Convertible Notes to be repurchased, plus accrued and unpaid special interest, if any, to, but excluding, the fundamental change repurchase date. In addition, following certain corporate events that occur prior to the maturity date of the Convertible Notes or if the Company delivers a notice of redemption in respect of some or all of the Convertible Notes, the Company will, in certain circumstances, increase the conversion rate of the Convertible Notes for a holder who elects to convert the Convertible Notes in connection with such a corporate event or convert the Convertible Notes called (or deemed called) for redemption during the related redemption period, as the case may be. Contemporaneously with the issuance of the Convertible Notes, Shake Shack Inc. entered into an intercompany note with SSE Holdings (“Intercompany Note”). SSE Holdings promises to pay Shake Shack Inc., for value received, the principal amount with interest of the Intercompany Note in March 2028. Shake Shack Inc. will exercise its right to convert the Intercompany Note to maintain at all times a one-to-one ratio between the number of common units, directly or indirectly, held by Shake Shack Inc. and the aggregate number of outstanding shares of common stock.

The Revolving Credit Facility has a maturity date of March 5, 2026. In fiscal 2023, the Company entered into the fourth amendment to the Revolving Credit Facility ("Fourth Amendment"), which, among other things, modified the benchmark interest rate to either: (i) the base rate plus applicable margin ranging from 0.0% to 1.5% or (ii) the Secured Overnight Financing Rate (“SOFR”) plus applicable margin ranging from 1.0% to 2.5%, in each case dependent upon the net lease adjusted leverage ratio. As of December 25, 2024 and December 27, 2023, no amounts were outstanding under the Revolving Credit Facility. The obligations under the Revolving Credit Facility are secured by a first-priority security interest in substantially all of the assets of SSE Holdings and the guarantors. The obligations under the Revolving Credit Facility are guaranteed by each of SSE Holdings' direct and indirect subsidiaries, with certain exceptions. The Revolving Credit Facility requires the Company to comply with maximum net lease adjusted leverage and minimum fixed charge coverage ratios, as well as other customary affirmative and negative covenants. As of December 25, 2024, the Company was in compliance with all covenants. The Revolving Credit Facility also permits the issuance of letters of credit upon our request of up to $15,000. As of December 25, 2024 and December 27, 2023, the Company had outstanding letters of credit of $3,894 and $3,147, respectively, in connection with the Revolving Credit Facility.

STOCKHOLDER'S EQUITY	STOCKHOLDERS' EQUITY LLC Interests The SSE Holdings LLC Agreement provides that holders of LLC Interests may, from time to time, require SSE Holdings to redeem all or a portion of their LLC Interests for newly-issued shares of Class A common stock on a one-for-one basis. In connection with any redemption or exchange, the Company receives a corresponding number of LLC Interests, increasing its total ownership interest in SSE Holdings. Simultaneously, and in connection with a redemption, the corresponding number of shares of Class B common stock are surrendered and cancelled. Refer to Note 12, Non-Controlling Interests, for additional information related to LLC Interests activity. Dividend Restrictions Shake Shack Inc. is a holding company with no direct operations. As a result, its ability to pay cash dividends on its common stock, if any, is dependent upon cash dividends, distributions or other transfers from SSE Holdings. The amounts available to pay cash dividends are subject to certain covenants and restrictions set forth in the Revolving Credit Facility. As of December 25, 2024, essentially all of the net assets of SSE Holdings were restricted.

Noncontrolling Interest [Abstract]
NON-CONTROLLING INTERESTS	NON-CONTROLLING INTERESTS Shake Shack is the primary beneficiary and sole managing member of SSE Holdings and, as a result, consolidates the financial results of SSE Holdings. The Company reports a non-controlling interest representing the economic interest held by the other members of SSE Holdings. The Third Amended and Restated Limited Liability Company Agreement, as further amended, (the "LLC Agreement") of SSE Holdings provides that holders of SSE Holdings, LLC membership interests ("LLC Interests") may, from time to time, require SSE Holdings to redeem all or a portion of their LLC Interests for newly-issued shares of Class A common stock on a one-for-one basis. In connection with any redemption or exchange, the Company will receive a corresponding number of LLC Interests, increasing the total ownership interest in SSE Holdings. Changes in the ownership interest in SSE Holdings while the Company retains its controlling interest in SSE Holdings will be accounted for as equity transactions. As such, future redemptions or direct exchanges of LLC Interests in SSE Holdings by the other members of SSE Holdings will result in a change in ownership and reduce the amount recorded as non-controlling interest and increase additional paid-in capital.

Restricted Stock Units In January 2015, the Company adopted the 2015 Incentive Award Plan (the "2015 Plan") under which it may grant up to 5,865,522 restricted stock units and other equity-based awards to team members, directors and officers. In June 2024, the Company amended and restated the 2015 Plan (the “2025 Plan”) which authorizes the issuance of up to 842,321 additional shares of the Company’s Class A Common Stock and extends the term of the 2015 Plan by 10 years, among other things. The restricted stock units granted generally vest equally over periods ranging from one A summary of restricted stock unit activity was as follows: Restricted Stock Units Weighted Average Grant Date Fair Value Outstanding and unvested as of December 27, 2023 511,544 $ 67.82 Granted 199,345 102.77 Vested (185,649) 70.31 Forfeited (82,436) 73.41 Outstanding and unvested as of December 25, 2024 442,804 $ 81.47 The weighted average grant-date fair value of restricted stock units granted during fiscal 2023 and fiscal 2022 were $58.26 and $71.25, respectively.

As of December 25, 2024, total unrecognized compensation expense related to unvested restricted stock units was $25,942, which is expected to be recognized over a weighted average period of 2.5 years. Performance Stock Units Under the 2025 Plan, the Company may grant performance stock units and other types of performance-based equity awards that vest based on the outcome of certain performance criteria that are established and approved by the Compensation Committee of the Board of Directors. The actual number of equity awards earned is based on the level of performance achieved over a predetermined performance period, relative to established financial goals. Performance stock units granted during fiscal 2024 are subject to a requisite service period and the awards vest ratably over four years or cliff vest over three years. The amount of awards that can be earned ranges from 0% to 200% of the number of performance stock units granted, based on the achievement of approved financial goals over a one-year or three-year performance period. Performance stock units containing market conditions are based on a Monte Carlo simulation, and related compensation expense is recognized using a graded attribution method over the vesting period and does not change regardless of the amount of shares received by the recipient based on achievement of the awards. The fair value of performance stock units not containing a market condition is determined based on the closing market price of the Company's Class A common stock on the date of grant. Compensation expense related to the performance stock units not containing a market condition is recognized using either a graded-vesting attribution method or straight-line over the vesting period based on the most probable outcome of the performance conditions. No performance stock units were granted during fiscal 2023 and fiscal 2022.

Income Tax Disclosure [Abstract]
INCOME TAXES	INCOME TAXES Shake Shack is the sole managing member of SSE Holdings, which is classified as a partnership for U.S federal and most applicable state and local income tax purposes. As the managing member, the Company consolidates SSE Holdings financial results. As a partnership, SSE Holdings is not subject to U.S. federal and certain state and local income taxes. Instead, any taxable income or loss generated by SSE Holdings is allocated to its members, including the Company, on a pro rata basis. The Company is subject to U.S. federal, state and local income taxes with respect to its allocable share of taxable income or loss from SSE Holdings, as well as any stand-alone income or loss generated by Shake Shack Inc. The Company is also subject to withholding taxes in foreign jurisdictions. Income Tax Expense The components of Income (loss) before income taxes were as follows: 2024 2023 2022 Domestic $ (18,247) $ (13,427) $ (49,454) Foreign 32,491 30,407 25,169 Income (loss) before income taxes $ 14,244 $ 16,980 $ (24,285) The components of Income tax expense (benefit) were as follows: 2024 2023 2022 Current income taxes: State and local $ 554 $ 1,271 $ 222 Foreign 3,924 3,793 3,612 Total current income taxes 4,478 5,064 3,834 Deferred income taxes: Federal (2,731) (12,427) (4,176) State and local 1,677 3,353 (838) Total deferred income taxes (1,054) (9,074) (5,014) Income tax expense (benefit) $ 3,424 $ (4,010) $ (1,180) Reconciliations of Income tax expense (benefit) computed at the U.S. federal statutory income tax rate to the recognized Income tax expense (benefit) and the U.S. statutory income tax rate to our effective tax rates were as follows: 2024 2023 2022 Expected U.S. federal income taxes at statutory rate $ 2,991 21.0 % $ 3,565 21.0 % $ (5,100) 21.0 % State and local income taxes, net of federal benefit 2,166 15.2 % 2,090 12.3 % (759) 3.1 % Foreign withholding taxes 3,924 27.6 % 3,792 22.3 % 3,612 (14.9) % Tax credits (7,033) (49.4) % (7,060) (41.6) % (5,969) 24.6 % Non-controlling interest (166) (1.2) % (196) (1.2) % 122 (0.5) % Non-deductible expenses 2,240 15.7 % 1,169 6.9 % 1,467 (6.0) % Reserve for uncertain tax positions — — % 154 0.9 % — — % Remeasurement of deferred tax assets in connection with other tax rate changes 392 2.8 % 1,547 9.1 % 225 (0.9) % Return to provision adjustment (650) (4.6) % (519) (3.0) % 267 (1.1) % Change in valuation allowance (97) (0.7) % (9,195) (54.1) % 4,955 (20.4) % Other (343) (2.4) % 643 3.8 % — — % Income tax expense (benefit) $ 3,424 24.0 % $ (4,010) (23.6) % $ (1,180) 4.9 % Shake Shack's effective income tax rates for fiscal 2024, fiscal 2023 and fiscal 2022 were 24.0%, (23.6)% and 4.9%, respectively. The increase in the effective income tax rate from fiscal 2023 to fiscal 2024 was primarily driven by the release of a valuation allowance and a higher remeasurement of deferred tax assets in fiscal 2023. Deferred Tax Assets and Liabilities The components of deferred tax assets and liabilities were as follows: December 25 December 27 Deferred tax assets: Investment in partnership $ 89,397 $ 90,419 Tax Receivable Agreement 67,192 64,076 Operating lease liability 5,264 4,713 Financing lease liability 124 114 Deferred revenue 209 196 Equity-based compensation 357 360 Net operating loss carryforwards 148,700 144,144 Tax credits 33,643 26,048 Other assets 1,772 947 Total gross deferred tax assets 346,658 331,017 Valuation allowance (260) (357) Total deferred tax assets, net of valuation allowance 346,398 330,660 Deferred tax liabilities: Property and equipment (537) (599) Operating lease right-of-use asset (4,147) (3,735) Financing lease right-of-use asset (119) (111) Other liabilities (9) (7) Total gross deferred tax liabilities (4,812) (4,452) Net deferred tax assets $ 341,586 $ 326,208 As of December 25, 2024, the Company's federal and state net operating loss carryforwards for income tax purposes were $615,782 and $334,359, respectively. Of the federal net operating loss carryforward, $563,915 can be carried forward indefinitely, while the remaining $51,867 will begin to expire in 2035. Similarly, of the state net operating loss carryforward, $106,682 can be carried forward indefinitely, while the remaining $227,677 will begin to expire in 2025. As of December 25, 2024, the Company had federal tax credit carryforwards, including a capital loss carryforward of $33,749, which will begin to expire in 2025 and gross state tax credit carryforwards of $273, also expiring in 2025. As described in Note 12, Non-controlling Interests, the Company acquired a total of 593,753 LLC Interests during fiscal 2024 through LLC Interest redemptions and stock-based compensation plan activity. Upon acquiring these LLC Interests, the Company recognized a deferred tax asset of $10,985 related to the basis difference in its investment in SSE Holdings. As of December 25, 2024, the total deferred tax asset associated with the basis difference was $89,397. The Company evaluates the realizability of its deferred tax assets on a quarterly basis and establishes valuation allowances when it is more likely than not that all or a portion of a deferred tax asset may not be realized. As of December 25, 2024, the Company concluded, based on the valuation of all available positive and negative evidence, that all of its deferred tax assets are more likely than not to be realized, except certain state credits and state net operating losses that are not expected to be utilized before expiration. Accordingly, the Company maintained a valuation allowance of $260. The net change in valuation allowance for fiscal 2024 was a decrease of $97. Refer to Schedule II, Valuation and Qualifying Accounts for additional information. Uncertain Tax Positions Pursuant to ASC 740, the Company provides for uncertain tax positions based upon our assessment of whether a tax benefit is more likely than not to be sustained upon examination by tax authorities. In 2024, no new uncertain tax positions were identified. A reconciliation of the beginning to the ending accounts of gross unrecognized tax benefits for fiscal 2024, 2023, and 2022 is as follows: 2024 2023 2022 Beginning balance $ 147 $ — $ — Additions for tax positions of prior years — 263 — Settlements — (116) — Ending balance $ 147 $ 147 $ — The Company files income tax returns in the United States federal and state and local jurisdictions. The Company is currently open to examination by tax authorities for state and local jurisdictions for tax years beginning 2018. Tax Receivable Agreement Pursuant to the Company's election under Section 754 of the Internal Revenue Code (the "Code"), the Company expects to obtain an increase in its share of the tax basis in the net assets of SSE Holdings when LLC Interests are redeemed or exchanged by the other members of SSE Holdings. The Company plans to make an election under Section 754 of the Code for each taxable year in which a redemption or exchange of LLC Interest occurs. The Company intends to treat any redemptions and exchanges of LLC Interests as direct purchases of LLC Interests for U.S. federal income tax purposes. These increases in tax basis may reduce the amounts that would otherwise be paid in the future to various tax authorities. They may also decrease gains (or increase losses) on future dispositions of certain capital assets to the extent tax basis is allocated to those capital assets. On February 4, 2015, the Company entered into a tax receivable agreement with certain then-existing non-controlling members of SSE Holdings (the "Tax Receivable Agreement"). This agreement obligates the Company to pay the non-controlling interest holders 85% of any tax benefits that the Company may actually realize, or deemed to realize, from (i) increases in the Company's share of the tax basis of SSE Holdings due to redemptions or exchanges of LLC Interests, (ii) tax basis increases resulting from payments made under the Tax Receivable Agreement, and (iii) deductions from imputed interest under the agreement (the "TRA Payments"). The Company expects to benefit from the remaining 15% of any realized tax benefits. The TRA Payments are not conditioned upon any continued ownership interest in SSE Holdings or us. Additionally, the rights of each non-controlling interest holder under the Tax Receivable Agreement, are assignable to transferees of its LLC Interests. During fiscal 2024, the Company acquired a total of 378,800 LLC Interests in connection with the redemption of LLC Interests, which led to an increase in the tax basis of its investment in SSE Holdings subject to the provisions of the Tax Receivable Agreement. The Company recognized an additional asset of $10,985 for the TRA Payments due to the redeeming members, representing 85% of the aggregate tax benefits the Company expects to realize from the tax basis increases related to the redemption of LLC Interests. This estimate was based on our conclusion that it was probable that such TRA Payments would be made, considering our projections of future taxable income. No payments were made to the members of SSE Holdings pursuant to the Tax Receivable Agreement in fiscal 2024 and fiscal 2023. As of December 25, 2024, the total amount of TRA Payments due under the Tax Receivable Agreement was $247,734, of which $717 amount was included in Other current liabilities on the Consolidated Balance Sheets.

Earnings Per Share [Abstract]
EARNINGS (LOSS) PER SHARE	EARNINGS (LOSS) PER SHARE Basic earnings (loss) per share of Class A common stock is computed by dividing Net income (loss) attributable to Shake Shack Inc. by the weighted average number of shares of Class A common stock outstanding during the period. Diluted earnings (loss) per share of Class A common stock is computed by dividing Net income (loss) attributable to Shake Shack Inc. by the weighted average number of shares of Class A common stock outstanding adjusted to give effect to potentially dilutive securities. The following table sets forth reconciliations of the numerators and denominators used to compute basic and diluted earnings (loss) per share of Class A common stock (in thousands, except per share amounts): 2024 2023 2022 Numerator: Net income (loss) attributable to Shake Shack Inc.—basic $ 10,207 $ 20,264 $ (21,229) Reallocation of net income attributable to non-controlling interests from the assumed conversion of Class B shares 613 726 — Net income (loss) attributable to Shake Shack Inc.—diluted $ 10,820 $ 20,990 $ (21,229) Denominator: Weighted average shares of Class A common stock outstanding—basic 39,830 39,419 39,237 Effect of dilutive securities: Stock options 52 75 — Performance stock units 69 11 — Restricted stock units 173 85 — Convertible Notes 1,467 1,467 — Shares of Class B common stock 2,612 2,842 — Weighted average shares of Class A common stock outstanding—diluted 44,203 43,899 39,237 Earnings (loss) per share of Class A common stock—basic $ 0.26 $ 0.51 $ (0.54) Earnings (loss) per share of Class A common stock—diluted $ 0.24 $ 0.48 $ (0.54) The effect of potential share settlement of the Convertible Notes outstanding for the period is included as potentially dilutive shares of Class A common stock under application of the if-converted method in the computation of diluted earnings (loss) per share, except when the effect would be anti-dilutive. Refer to Note 8, Debt, for additional information. Shares of Class B common stock do not share in the earnings or losses of Shake Shack and are therefore not participating securities. As such, separate presentation of basic and diluted earnings (loss) per share of Class B common stock under the two-class method has not been presented. However, shares of Class B common stock outstanding for the period are considered potentially dilutive shares of Class A common stock under application of the if-converted method and are included in the computation of diluted earnings (loss) per share, except when the effect would be anti-dilutive.

NOTE 1: ORGANIZATION Shake Shack Inc. (the "Parent Company") was formed on September 23, 2014 as a Delaware corporation and is a holding company with no direct operations. The Parent Company's assets consist primarily of its equity interest in SSE Holdings, LLC ("SSE Holdings"), certain deferred tax assets and its note receivable from SSE Holdings. The Parent Company's cash inflows are primarily from cash dividends or distributions and other transfers from SSE Holdings. The amounts available to the Parent Company to fulfill cash commitments and pay cash dividends on its common stock are subject to certain restrictions in SSE Holdings' Revolving Credit Facility. Refer to Note 8, Debt, in the accompanying Consolidated Financial Statements, for additional information. These Condensed Parent Company financial statements should be read in conjunction with the Consolidated Financial Statements of Shake Shack Inc. and the accompanying notes thereto, included in Part II, Item 8. For purposes of these condensed financial statements, the Parent Company's interest in SSE Holdings is recorded based upon its proportionate share of SSE Holdings' net assets (similar to presenting them on the equity method). The Parent Company is the sole managing member of SSE Holdings, and pursuant to the Third Amended and Restated LLC Agreement of SSE Holdings (the “SSE Holdings LLC Agreement”), receives compensation in the form of reimbursements for all costs associated with being a public company and maintaining its existence.

As of December 25, 2024 and December 27, 2023, the balance of the Note receivable from SSE Holdings was $224,879 and $216,946, respectively, net of accretion.

Cybersecurity Risk Management Processes for Assessing, Identifying, and Managing Threats [Text Block]	We have developed and implemented a cybersecurity risk management program intended to protect the confidentiality, integrity, and availability of our critical systems and information. Our cybersecurity risk management program includes a cybersecurity incident response plan. Our cybersecurity risk management program is informed by the National Institute of Standards and Technology (‘NIST’) Cybersecurity Framework (‘CSF’) and incorporates its principles in assessing, identifying, and managing cybersecurity risks relevant to our business. While we leverage the NIST CSF as a foundational guide, our program is tailored to our specific operational and risk environment. Our cybersecurity risk management program is integrated into our overall enterprise risk management program, and shares common methodologies, reporting channels and governance processes that apply across the enterprise risk management program to other legal, compliance, strategic, operational, and financial risk areas. Our cybersecurity risk management program includes: ▪ Risk assessments designed to help identify material cybersecurity risks to our critical systems, information, products, services, and our broader enterprise IT environment; ▪ A security team led by our Chief Information and Technology Officer principally responsible for managing our (1) cybersecurity risk assessment processes, (2) security controls, and (3) response to cybersecurity incidents; ▪ the use of external service providers, where appropriate, to assess, test or otherwise assist with aspects of our security controls and designed to anticipate cyber-attacks and prevent breaches; ▪ cybersecurity awareness training of our employees, incident response personnel, and senior management; ▪ a cybersecurity incident response plan that includes procedures for responding to cybersecurity incidents; and ▪ a structured third-party risk management program that includes due diligence, contractual security requirements, and continuous monitoring for service providers, suppliers, and vendors to mitigate risks associated with external partnerships.. Cybersecurity risks are actively monitored through continuous security assessments, real-time threat intelligence, and adaptive security controls, enable proactive adjustments to our security program as threats evolve. As part of our ongoing cybersecurity risk management program, we have from time-to-time identified risks or threats to our digital and corporate systems, including attempts to obtain team member credentials through bot and phishing attacks or through social engineering. While these risks and threats, as well as others we identify, require active and ongoing efforts to mitigate, we have not currently identified any prior cybersecurity incidents, that have materially affected or are reasonably likely to materially affect us, including our operations, business strategy, results of operations, or financial condition.

SUMMARY OF SIGNIFICANT ACCOUN_2

SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (Policies)	12 Months Ended
	Dec. 25, 2024
Accounting Policies [Abstract]
Basis of Presentation	Basis of Presentation The accompanying Consolidated Financial Statements have been prepared in accordance with accounting principles generally accepted in the United States of America ("GAAP") and include the accounts of Shake Shack Inc. and its subsidiaries. All intercompany accounts and transactions have been eliminated in consolidation. Certain reclassifications have been made to prior period amounts to conform to the current year presentation. SSE Holdings is considered a variable interest entity. Shake Shack Inc. is the primary beneficiary as the Company has the majority economic interest in SSE Holdings and, as the sole managing member, has decision making authority that significantly affects the economic performance of the entity, while the limited partners have no substantive kick-out or participating rights. As a result, the Company consolidates SSE Holdings. The assets and liabilities of SSE Holdings represent substantially all of the Company's consolidated assets and liabilities with the exception of certain deferred taxes and liabilities under the Tax Receivable Agreement. As of December 25, 2024 and December 27, 2023, the net assets of SSE Holdings were $413,793 and $388,250, respectively. The assets of SSE Holdings are subject to certain restrictions in SSE Holdings' revolving credit agreement. Refer to Note 8, Debt, and Note 14, Income Taxes, for additional information.
Fiscal Year	Fiscal Year The Company operates on a 52/53 week fiscal year ending on the last Wednesday of December. Fiscal 2024 contained 52 weeks and ended on December 25, 2024 ("fiscal 2024"). Fiscal 2023 contained 52 weeks and ended on December 27, 2023 ("fiscal 2023"). Fiscal 2022 contained 52 weeks and ended on December 28, 2022 ("fiscal 2022"). Unless otherwise stated, references to years in this report relate to fiscal years.
Use of Estimates	Use of Estimates The preparation of these Consolidated Financial Statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements, and the reported amounts of sales and expenses during the reporting period. Actual results could differ from those estimates.
Fair Value Measurements	Fair Value Measurements The Company applies fair value accounting for all financial assets and liabilities and non-financial assets and liabilities that are recognized or disclosed at fair value in the financial statements on a recurring basis. Assets and liabilities are categorized based on the priority of the inputs to the valuation technique into a three-level fair value hierarchy as set forth below. ▪ Level 1 — Quoted prices in active markets for identical assets or liabilities. ▪ Level 2 — Observable inputs other than quoted prices in active markets for identical assets or liabilities, quoted prices for identical assets or liabilities in inactive markets, or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the asset or liability. ▪ Level 3 — Inputs that are both unobservable and significant to the overall fair value measurements reflecting an entity's estimates of assumptions that market participants would use in pricing the asset or liability.
Cash and Cash Equivalents	Cash and Cash Equivalents Cash and cash equivalents consist primarily of cash on hand, deposits with banks, money market funds and short-term, highly liquid investments that have original maturities of three months or less. Cash equivalents are stated at cost, which approximates fair value.
Marketable Securities	Marketable Securities Marketable securities classified as held-to-maturity securities consist of U.S. Treasuries for which the Company has the ability and intent to hold to maturity and are reported at amortized cost, net of a valuation allowance for credit losses. Interest income and the amortization of discounts and premiums are recorded in Other income, net on the Consolidated Statements of Income (Loss). No expected credit losses were recognized as of December 25, 2024 and December 27, 2023.
Accounts Receivable, Net	Accounts Receivable, Net
Inventories	Inventories Inventories, which consist of food, paper goods, beverages, beer, wine and retail merchandise, are valued at the lower of weighted average cost or net realizable value. No adjustment is deemed necessary to reduce inventory to net realizable value due to the rapid turnover and high utilization of inventory.
Property and Equipment, Net And Valuation of Long-lived Assets	Property and Equipment, Net Property and equipment, net is stated at historical cost less accumulated depreciation. Property and equipment are depreciated using the straight-line method over the estimated useful lives of the assets, which generally range from five two Costs incurred when constructing Shacks are capitalized. The cost of repairs and maintenance are expensed when incurred. Costs for refurbishments and improvements that significantly increase the productive capacity or extend the useful life of the assets are capitalized. When assets are disposed, the resulting gain or loss is recognized in Impairments, loss on disposal of assets, and Shack closures on the Consolidated Statements of Income (Loss). Valuation of Long-lived Assets The Company assesses potential impairments to its long-lived assets, which include property and equipment and operating and finance lease right-of-use assets, whenever events or circumstances indicate that the carrying value of an asset may not be recoverable. The recoverability evaluation is first performed at the market service area level ("MSA"). If the carrying value of the MSA exceeds its estimated undiscounted future cash flows, a secondary recoverability test is performed for all individual Shacks within the identified MSA. An impairment charge is recognized when the carrying amount of the asset exceeds the fair value of the asset, considering external market participant assumptions, and is allocated across all assets of the impaired Shack. Since
Deferred Financing Costs	Deferred Financing Costs Deferred financing costs incurred in connection with the issuance of long-term debt and establishing credit facilities are capitalized and amortized in Interest expense on the Consolidated Statements of Income (Loss) based on the related debt agreements. Deferred financing costs are included in Other assets on the Consolidated Balance Sheets.
Other Assets	Other Assets Other assets consist primarily of capitalized implementation costs from cloud computing arrangements, certain custom pre-ordered furniture, fixtures and equipment for future and existing Shacks, transferable liquor licenses, and security deposits. Implementation costs associated with cloud computing arrangements hosted by third-party vendors are capitalized when incurred during the application development phase. Amortization is calculated on a straight-line basis over the contractual term of the cloud computing arrangement and is recorded within General and administrative expenses on the Consolidated Statements of Income (Loss). As of December 25, 2024 and December 27, 2023, capitalized implementation costs from cloud computing arrangements totaled $4,051 and $5,572, respectively, net of accumulated amortization. The costs of obtaining non-transferable liquor licenses that are directly issued by local government agencies for nominal fees are expensed as incurred. The costs of purchasing transferable liquor licenses through open markets in jurisdictions with a limited number of authorized liquor licenses are capitalized as indefinite-lived intangible assets. Annual liquor license renewal fees, for both types of licenses, are expensed over the renewal term. As of December 25, 2024 and December 27, 2023, indefinite-lived intangible assets relating to transferable liquor licenses totaled $2,040 and $1,903, respectively. Indefinite-lived intangible assets are evaluated for impairment at least annually during the fourth quarter, and whenever events or circumstances indicate that an impairment may exist. When evaluating intangible assets for impairment, the Company first performs a qualitative assessment to determine whether it is more likely than not that an intangible asset group is impaired. If determined that it is more likely than not that the carrying value of the intangible asset group exceeds its fair value, the Company performs a quantitative assessment to derive the fair value of the intangible asset group. If the carrying value of the intangible asset group exceeds the estimated fair value, an impairment charge is recorded to reduce the carrying value to the estimated fair value. In addition, the Company continuously monitors and may revise the useful lives of intangible assets when facts and circumstances change.
Revenue Recognition	Revenue Recognition Shack Sales Revenue from Shack sales is recognized when payment is tendered at the point of sale, net of discounts, as the performance obligation has been satisfied at that time. Sales tax collected from guests is excluded from Shack sales and the obligation is included in Other current liabilities on the Consolidated Balance Sheets until the taxes are remitted to the appropriate taxing authorities. Delivery services are fulfilled by third-party delivery partners whether ordered through the Shack app, website (collectively, "Company-owned platforms") or through third-party delivery platforms. Revenue from orders through Company-owned platforms includes delivery fees and is recognized when the delivery partner transfers the order to the guest as the Company controls the delivery. For these sales, the Company receives payment directly from the guest at the time of sale. Revenue from orders through third-party delivery platforms is recognized when the order is transferred to the third-party delivery partner and excludes delivery fees collected by the delivery partner as the Company does not control the delivery. The Company receives payment from the delivery partner subsequent to the transfer of the order and the payment terms are short-term in nature. For all delivery sales, the Company is considered the principal and recognizes revenue on a gross basis. The Company sells gift cards which do not have expiration dates. Revenue from gift cards is recognized when gift cards are redeemed by the guest or, in the event a gift card is not expected to be redeemed, in proportion to actual redemptions of gift cards ("gift card breakage"). The gift card breakage rate is determined from historical gift card redemption patterns. Gift card breakage income for fiscal 2024, 2023, and 2022 was $413, $327 and $1,472, respectively. During fiscal 2022, the Company concluded it had accumulated a sufficient level of historical data from a large pool of homogeneous transactions to allow it to reasonably and objectively determine an estimated gift card breakage rate and the pattern of actual gift card redemptions. In accordance with ASC 250, Accounting Changes and Error Corrections, the Company concluded that this accounting change represented a change in accounting estimate. As a result, a cumulative catch-up adjustment was recorded during fiscal 2022 that resulted in $1,281 of gift card breakage income. Gift card breakage income is included in Shack sales on the Consolidated Statements of Income (Loss). Licensing Revenue Licensing revenue includes initial territory fees, Shack opening fees and ongoing sales-based royalty fees from licensed Shacks. Generally, the licenses granted to develop, open and operate each Shack in a specified territory are the predominant good or service transferred to the licensee and represent distinct performance obligations. Ancillary promised services, such as training and assistance during the initial opening of a Shack, are typically combined with the license and considered one performance obligation per Shack. The Company determines the transaction price for each contract, which requires judgment as the transaction price is comprised of the initial territory fee and an estimate of the total Shack opening fees based on the estimated number of Shacks the Company expects the licensee to open. The transaction price is then allocated equally to each Shack expected to open. The performance obligation is satisfied over time, starting when a Shack opens through the end of the license term for the related Shack, therefore revenue is recognized on a straight-line basis over the license term. Generally, payment for the initial territory fee is received upon execution of the license agreement and payment for the Shack opening fees is received either in advance of or upon opening the related Shack. These payments are initially deferred and recognized in revenue as the performance obligations are satisfied. Revenue from sales-based royalties is recognized as the related sales occur.
Equity-based Compensation	Equity-based Compensation Equity-based compensation expense is measured based on the grant-date fair value of the awards. For awards with graded-vesting features and service conditions only, compensation expense is recognized on a straight-line basis over the total requisite service period for the entire award. For awards with graded-vesting features and a combination of service and performance conditions, compensation expense is recognized using a graded-vesting attribution method over the vesting period based on the most probable outcome of the performance conditions. For awards with cliff vesting features and a combination of service and performance conditions, compensation expense is recognized on a straight-line basis over the total requisite service period for the entire award based on the most probable outcome of the performance conditions. For awards that contain a market condition, a Monte Carlo simulation valuation model is used to calculate the grant-date fair value. The assumptions used in the valuation include expected term, volatility, risk-free interest rate, and closing price as of the valuation date. Compensation expense for awards containing a market condition is recognized ratably over the performance period regardless of whether the market condition and requisite service period are met. Actual distributed shares are calculated upon conclusion of the service and performance periods. Forfeitures are recognized as they occur for all equity awards. Equity-based compensation expense is included in General and administrative expenses and Labor and related expenses on the Consolidated Statements of Income (Loss).
Leases	Leases Shake Shack currently leases all of its Company-operated Shacks, the home office and certain equipment under various non-cancelable lease agreements that expire on various dates through 2045. The Company evaluates contracts entered into to determine whether the contract involves the use of property or equipment, which is either explicitly or implicitly identified in the contract. The Company evaluates whether it controls the use of the asset, which is determined by assessing whether substantially all economic benefit from the use of the asset is obtained, and whether the Company has the right to direct the use of the asset. If these criteria are met, the Company has identified a lease, within the contract, and therefore a right of use asset and lease liability are recorded on the Consolidated Balance Sheets. Upon possession of a leased asset, the Company determines whether the lease is an operating or finance lease. All of the Company's real estate leases are classified as operating leases and most equipment leases are classified as finance leases. Generally, real estate leases have initial terms ranging from 10 to 15 years and typically include two five-year renewal options. Renewal options are generally not recognized as part of the right-of-use assets and lease liabilities as it is not reasonably certain at commencement date that the Company would exercise the renewal options. Real estate leases typically contain fixed minimum rent payments and/or contingent rent payments which are based upon sales in excess of specified thresholds. When the achievement of such sales thresholds are deemed to be probable, contingent rent is accrued in proportion to the sales recognized during the period. For operating leases, fixed lease payments are recognized as operating lease costs on a straight-line basis over the lease term and are reported in specific line items on the Consolidated Statements of Income (Loss). Lease expense incurred before a Shack opens is recorded in Pre-opening costs. Once a Company-operated Shack opens, the straight-line lease expense and contingent rent, if applicable, are recorded in Occupancy and related expenses. Many of these leases also require the Company to pay real estate taxes, common area maintenance costs and other occupancy costs which are included in Occupancy and related expenses. Finance leases are recognized in depreciation expense on a straight-line basis over the remaining lease term, along with recognition of interest expense associated with accretion of the lease liability. For both operating and finance leases that contain lease and non-lease components, the components are combined and accounted for as a single lease component. Variable lease costs for both operating and finance leases, if any, are recognized as incurred. Leases with a term of 12 months or less are deemed short-term and are not recognized on the Consolidated Balance Sheets. Fixed lease payments for short-term leases are recognized on a straight-line basis over the lease term. The Company calculates operating lease right-of-use assets and lease liabilities as the present value of fixed lease payments over the reasonably certain lease term beginning at the commencement date. The Company uses its incremental borrowing rate (“IBR”) in determining the present value of future lease payments as there are no explicit rates provided in the leases. The IBR used to measure the lease liability is derived from the average of the yield curves obtained from using the notching method and the recovery rate method. The most significant assumption in calculating the IBR is the Company's credit rating and is subject to judgment. The credit rating used to develop the IBR is determined by utilizing the credit ratings of other public companies with similar financial information as SSE Holdings. The Company expends cash for leasehold improvements to build out and equip leased properties. Generally, a portion of the leasehold improvements and building costs are reimbursed by the landlords through landlord incentives pursuant to agreed-upon terms in the lease agreements. Landlord incentives usually take the form of cash, full or partial credits against future minimum or contingent rents otherwise payable by the Company, or a combination thereof. In most cases, landlord incentives are received after the Company takes possession of the property and as milestones are met during the construction of the property. The Company includes these amounts in the measurement of the initial operating lease liability and right-of-use asset.
Pre-opening Costs	Pre-opening Costs Pre-opening costs are expensed as incurred and consist primarily of occupancy, manager and team member wages, cookware, travel and lodging costs for the opening training team and other supporting team members, marketing expenses, legal fees, and inventory costs incurred prior to the opening of a Shack.
Income Taxes	Income Taxes Income taxes are accounted for pursuant to the asset and liability method which requires the recognition of deferred income tax assets and liabilities related to the expected future tax consequences arising from temporary differences between the carrying values and tax bases of assets and liabilities based on enacted statutory tax rates applicable to the periods in which the temporary differences are expected to reverse. Any effects of changes in income tax rates or laws are included in Income tax expense on the Consolidated Statements of Income (Loss) in the period of enactment. A valuation allowance is recognized if we determine it is more likely than not that all or a portion of a deferred tax asset will not be recognized. In making such determination, the Company considers all available evidence, including scheduled reversals of deferred tax liabilities, projected future taxable income, tax planning strategies, and recent and expected future results of operations.
