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 28, 2022 and December 29, 2021, the net assets of SSE Holdings were $362,571 and $376,857, 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 year 2022 contained 52 weeks and ended on December 28, 2022 ("fiscal 2022"). Fiscal year 2021 contained 52 weeks and ended on December 29, 2021 ("fiscal 2021"). Fiscal year 2020 contained 53 weeks and ended on December 30, 2020 ("fiscal 2020"). 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. Segment Reporting The chief operating decision maker (the "CODM") is the Chief Executive Officer. The Company determined it has one operating segment and one reportable segment, as the CODM regularly reviews Shack operations and financial performance at a consolidated level to allocate resources. 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 consist of mutual funds that primarily invest in corporate bonds, certificates of deposits, asset-backed securities, commercial paper, U.S. Treasury obligations, and foreign government securities. Marketable securities are recorded at fair value, with unrealized gains and losses recorded in Other income (expense), net. Dividend and interest income are recognized when earned and are recorded in Other income (expense), net on the Consolidated Statements of Loss. 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 is 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 Impairment and loss on disposal of assets on the Consolidated Statements of Loss. Valuation of Long-lived Assets The Company assesses potential impairments to our long-lived assets, which include property and equipment and operating lease right-of-use assets, whenever events or circumstances indicate that the carrying value of an asset may not be recoverable. Recoverability of an asset is measured by a comparison of the carrying value of the asset group to the estimated undiscounted future cash flows expected to be generated by the asset group. If the carrying value of the asset group exceeds its estimated undiscounted future cash flows, an impairment charge is recognized in the amount by which the carrying value of the asset exceeds the fair value of the asset, considering external market participant assumptions. 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 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 Loss. As of December 28, 2022 and December 29, 2021, capitalized implementation costs from cloud computing arrangements totaled $6,212 and $6,431, 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 28, 2022 and December 29, 2021, indefinite-lived intangible assets relating to transferable liquor licenses totaled $1,837 and $1,461, respectively. Indefinite-lived intangible assets are evaluated for impairment 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 primarily consists of Shack sales and Licensing revenue. Generally, revenue is recognized as promised goods or services transfer to the guest or customer in an amount that reflects the consideration the Company expects to be entitled to in exchange for those goods or services. 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. Sales tax collected from guests is excluded from Shack sales and the obligation is included as sales tax payable until the taxes are remitted to the appropriate taxing authorities. Revenue from gift cards is deferred and recognized over time as redemptions occur. Delivery services are fulfilled by third-party delivery partners whether ordered through the Shack app and website ("Company-owned platforms") or though third-party delivery partners. 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 partners 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 order and the payment terms are short-term in nature. For all delivery sales, the Company is considered the principal and recognizes the revenue on a gross basis. During fiscal 2022, the Company concluded it has 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. Accordingly, the Company recognizes breakage income and reduces the related gift card liability for unredeemed gift cards in proportion to actual redemptions of gift cards. The Company will continue to review historical gift card redemption information at each reporting period to assess the continued appropriateness of the gift card breakage rate and pattern of redemption. 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. Inclusive of this cumulative catch-up, $1,472 of gift card breakage income was recognized during fiscal 2022. Gift card breakage income is included in Shack sales in the Consolidated Statements of Loss. 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 is comprised of the initial territory fee and an estimate of the total Shack opening fees the Company expects to be entitled to. The calculation of total Shack opening fees included in the transaction price requires judgment, as it is based on an 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 or upon opening the related Shack. These payments are initially deferred and recognized in revenue as the performance obligations are satisfied, which occurs over a long-term period. 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. 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 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 amounted to $12,376, $5,677 and $1,449 in fiscal 2022, fiscal 2021 and fiscal 2020, respectively, and are included in General and administrative expense and Other operating expenses on the Consolidated Statements of Loss. Leases Shake Shack currently leases all of its domestic Company-operated Shacks, the home office and certain equipment under various non-cancelable lease agreements that expire on various dates through 2044. 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 benefits 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 and the Company has identified a lease, 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. Lease expense incurred before a Shack opens is recorded in Pre-opening costs on the Consolidated Statements of Loss. Once a domestic Company-operated Shack opens, the straight-line lease expense and contingent rent, if applicable, are recorded in Occupancy and related expenses on the Consolidated Statements of Loss. Many of the 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 on the Consolidated Statements of Loss. 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, is recognized as incurred. For leases with a lease term of 12 months or less ("short-term lease"), any fixed lease payments are recognized on a straight-line basis over such term, and are not recognized on the Consolidated Balance Sheets. The Company calculates operating lease 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, which are also reflected as a reduction to the initial measurement of the 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 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 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 ten 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 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. Total amortization expense was $1,047 and $867, respectively, for fiscal 2022 and fiscal 2021, and was included in Interest expense in the Consolidated Statements of Loss. In connection with the issuance of the Convertible Notes, the Company also incurred consulting and advisory fees of $231 during fiscal 2021 and was included in General and administrative expenses in the Consolidated Statements of Loss. No amounts for consulting and advisory fees were incurred during fiscal 2022. The fair value of the Convertible Notes was approximately $162,500 and $206,018, respectively, as of December 28, 2022 and December 29, 2021, 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. Revolving Credit Facility The Company maintains a revolving credit facility agreement ("Revolving Credit Facility") which permits borrowings up to $50 million and issuance of letters of credit upon the Company's request of up to $15 million. As of December 28, 2022 and December 29, 2021, no amounts were outstanding under the Revolving Credit Facility. In August 2022, the Company entered into an irrevocable standby letter of credit to secure obligations under the workers' compensation insurance coverage in the amount of $1,260, which expires in July 2023 and renews automatically for one-year periods. As of December 28, 2022, the Company maintained $1,863 of letters of credit in connection with the Revolving Credit Facility. The Company maintained a letter of credit of $603 in connection with the Revolving Credit Facility as of December 29, 2021. As of December 28, 2022, the Revolving Credit Facility had unamortized deferred financing costs of $62 which were included in Other assets on the Consolidated Balance Sheets. Total interest expense related to the Revolving Credit Facility was $82, $479 and $531, respectively, for fiscal 2022, fiscal 2021 and fiscal 2020. Interest expense for fiscal 2021 primarily included the write-off of previously capitalized costs on the Revolving Credit Facility. 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 28, 2022, the Company was in compliance with all covenants.

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 in SSE Holdings 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 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. The following table summarizes the ownership interest in SSE Holdings: 2022 2021 LLC Interests Ownership % LLC Interests Ownership % Number of LLC Interests held by Shake Shack Inc. 39,284,998 93.2 % 39,142,397 93.1 % Number of LLC Interests held by non-controlling interest holders 2,869,513 6.8 % 2,921,587 6.9 % Total LLC Interests outstanding 42,154,511 100.0 % 42,063,984 100.0 % The weighted average ownership percentages for the applicable reporting periods are used to attribute Net loss and Other comprehensive loss to Shake Shack Inc. and the non-controlling interest holders.

Income Tax Disclosure [Abstract]
INCOME TAXES	INCOME TAXESShake Shack is the sole managing member of SSE Holdings and, as a result, consolidates the financial results of SSE Holdings. SSE Holdings is treated as a partnership for U.S. federal and most applicable state and local income tax purposes. As a partnership, SSE Holdings is not subject to U.S. federal and certain state and local income taxes. Any taxable income or loss generated by SSE Holdings is passed through to and included in the taxable income or loss of its members, including the Company, on a pro rata basis. The Company is subject to U.S. federal income taxes, in addition to state and local income taxes with respect to its allocable share of any taxable income or loss of 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 Loss before income taxes were as follows: 2022 2021 2020 Domestic $ (49,454) $ (38,833) $ (59,873) Foreign 25,169 21,498 14,396 Loss before income taxes $ (24,285) $ (17,335) $ (45,477) The components of Income tax expense (benefit) were as follows: 2022 2021¹ 2020 Current income taxes: Federal $ — $ — $ — State and local 1,427 275 190 Foreign 3,612 2,880 1,223 Total current income taxes 5,039 3,155 1,413 Deferred income taxes: Federal (4,939) (11,921) (12,638) State and local 1,582 1,542 11,282 Total deferred income taxes (3,357) (10,379) (1,356) Income tax expense (benefit) $ 1,682 $ (7,224) $ 57 (1) For fiscal 2021, certain amounts were reclassified for consistent presentation with the current year. 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: 2022 2021¹ 2020 Expected U.S. federal income taxes at statutory rate $ (5,100) 21.0 % $ (3,641) 21.0 % $ (9,550) 21.0 % State and local income taxes, net of federal benefit 2,103 (8.7) % 2,539 (14.6) % 5,776 (12.7) % Foreign withholding taxes 3,612 (14.9) % 2,880 (16.6) % 1,223 (2.7) % Tax credits (5,969) 24.6 % (3,655) 21.1 % (1,533) 3.4 % Non-controlling interest 122 (0.5) % (350) 2.0 % 537 (1.2) % Remeasurement of deferred tax assets in connection with other tax rate changes 225 (0.9) % 1,034 (6.0) % 5,433 (11.9) % Change in valuation allowance 4,955 (20.4) % (6,059) 35.0 % (2,264) 5.0 % Other 1,734 (7.1) % 28 (0.2) % 435 (1.0) % Income tax expense (benefit) $ 1,682 (6.9) % $ (7,224) 41.7 % $ 57 (0.1) % (1) For fiscal 2021, certain amounts were reclassified for consistent presentation with the current year. Shake Shack's effective income tax rates for fiscal 2022, fiscal 2021 and fiscal 2020 were (6.9)%, 41.7% and (0.1)%, respectively. The decrease in our effective income tax rate from fiscal 2021 to fiscal 2022 was primarily driven by additional expense related to an increase in valuation allowance, increase in foreign tax expense, net expense related to equity-based compensation, partially offset by higher tax credits. The increase in our effective income tax rate from fiscal 2020 to fiscal 2021 was primarily driven by the increase in the income tax benefit from the release of the valuation allowance and higher tax credits, partially offset by higher foreign tax expense. Deferred Tax Assets and Liabilities The components of deferred tax assets and liabilities were as follows: December 28 December 29 2021 (1) Deferred tax assets: Investment in partnership $ 89,660 $ 116,639 Tax Receivable Agreement 64,218 63,983 Operating lease liability 4,376 3,873 Financing lease liability 61 63 Deferred revenue 167 150 Equity-based compensation 380 263 Net operating loss carryforwards 134,989 108,207 Tax credits 19,257 13,297 Other assets 638 574 Total gross deferred tax assets 313,746 307,049 Valuation allowance (9,560) (5,173) Total deferred tax assets, net of valuation allowance 304,186 301,876 Deferred tax liabilities: Property and equipment (95) (21) Operating lease right-of-use asset (3,488) (3,121) Financing lease right-of-use asset (58) (61) Other liabilities (7) (5) Total gross deferred tax liabilities (3,648) (3,208) Net deferred tax assets $ 300,538 $ 298,668 (1) For fiscal 2021, certain amounts were reclassified for consistent presentation with the current year. As of December 28, 2022, the Company's federal and state net operating loss carryforwards for income tax purposes were $558,397 and $303,323. If not utilized, $506,530 of the Company's federal net operating losses can be carried forward indefinitely, and the remainder will begin to expire in 2035. If not utilized $48,587 of the Company's state net operating loss carryforwards can be carried forward indefinitely, and the remainder will begin to expire in 2023. As of December 28, 2022, the Company had federal tax credit carryforwards of $18,660 which will begin to expire in 2025 and gross state tax credits of $756 which will begin to expire in 2023. As described in Note 11, Stockholders' Equity, the Company acquired an aggregate of 142,601 LLC Interests in connection with the redemption of LLC Interests and activity relating to its stock compensation plan during fiscal 2022. The Company recognized a deferred tax liability in the amount of $1,137 associated with the basis difference in its investment in SSE Holdings upon acquisition of these LLC Interests. As of December 28, 2022, the total deferred tax asset related to the basis difference in the Company's investment in SSE Holdings was $89,660. 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 28, 2022, the Company concluded, based on the weight of all available positive and negative evidence, that all of its deferred tax assets are more likely than not to be realized, except New York City UBT and certain foreign tax credits no longer expected to be utilized before expiration. As such, a valuation allowance in the amount of $9,560 was recognized. The net change in valuation allowance for fiscal 2022 was an increase of $4,387. Refer to Schedule II, Valuation and Qualifying Accounts for additional information. Uncertain Tax Positions There were no reserves for uncertain tax positions as of December 28, 2022 and December 29, 2021. Shake Shack Inc. was formed in September 2014 and did not engage in any operations prior to the IPO and Organizational Transactions. The statute of limitations remains open for tax years beginning in 2015 for Shake Shack Inc. Additionally, although SSE Holdings is treated as a partnership for U.S. federal and state income taxes purposes, it is still required to file an annual U.S. Return of Partnership Income, which is subject to examination by the Internal Revenue Service ("IRS"). The statute of limitations has expired for tax years through 2018 for SSE Holdings. 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 of the then-existing members of SSE Holdings (the "Tax Receivable Agreement") that provides for the payment by the Company of 85% of the amount of any tax benefits that are actually realized, or in some cases are deemed to realize, as a result of (i) increases in the Company's share of the tax basis in the net assets of SSE Holdings resulting from any redemptions or exchanges of LLC Interests, (ii) tax basis increases attributable to payments made under the Tax Receivable Agreement, and (iii) deductions attributable to imputed interest pursuant to the Tax Receivable Agreement (the "TRA Payments"). The Company expects to benefit from the remaining 15% of any tax benefits that may actually realize. The TRA Payments are not conditioned upon any continued ownership interest in SSE Holdings or the Company. The rights of each member of SSE Holdings that is a party to the Tax Receivable Agreement, are assignable to transferees of their respective LLC Interests. During fiscal 2022, the Company acquired an aggregate of 52,074 LLC Interests in connection with the redemption of LLC Interests, which resulted in 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 liability in the amount of $844 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, after concluding it was probable that such TRA Payments would be paid based on estimates of future taxable income. No payments were made to the members of SSE Holdings pursuant to the Tax Receivable Agreement in fiscal 2022 and fiscal 2021. As of December 28, 2022, the total amount of TRA Payments due under the Tax Receivable Agreement was $234,893, of which no amount was included in Other current liabilities on the Consolidated Balance Sheets. Refer to Note 17, Commitments and Contingencies, for additional information relating to the liabilities under the Tax Receivable Agreement. CARES Act On March 27, 2020, the U.S. government enacted the Coronavirus Aid, Relief, and Economic Security Act (the "CARES Act") to provide certain relief as a result of the COVID-19 pandemic. The CARES Act provides tax relief, along with other stimulus measures, including a provision for an Employee Retention Credit ("ERC") and retroactive technical correction of prior tax legislation for tax depreciation of certain qualified improvement property, among other changes. The CARES Act allows for a five-year carryback of federal NOLs generated in 2018 through 2020 and eliminates the 80% taxable income limitation by allowing corporate entities to fully utilize NOL carryforwards to offset taxable income in 2018 through 2020. As there is no authoritative guidance under U.S. GAAP on accounting for government assistance to for-profit business entities, the Company accounts for the ERC by analogy to International Accounting Standard ("IAS") 20, Accounting for Government Grants and Disclosure of Government Assistance. Subsequent to the second quarter of 2020, we began deferring the employer-paid portion of social security taxes; 50% of this was recognized at the end of 2021 and the other 50% and the end of 2022 as required by the CARES Act. Inflation Reduction Act On August 16, 2022, the U.S. government enacted the Inflation Reduction Act (“IRA”) into law. The IRA, among other things, enacted a 15% corporate minimum tax effective for tax years after December 31, 2022, a 1% tax on share repurchases after December 31, 2022, and created and extended certain tax-related energy incentives. The Company currently does not expect the tax-related provisions of the IRA to have a material impact on our financial results.

Earnings Per Share [Abstract]
EARNINGS (LOSS) PER SHARE	EARNINGS (LOSS) PER SHARE Basic loss per share of Class A common stock is computed by dividing Net loss attributable to Shake Shack Inc. by the weighted average number of shares of Class A common stock outstanding during the period. Diluted loss per share of Class A common stock is computed by dividing Net 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): 2022 2021 2020 Numerator: Net loss attributable to Shake Shack Inc.—basic $ (24,091) $ (8,655) $ (42,158) Net loss attributable to Shake Shack Inc.—diluted $ (24,091) $ (8,655) $ (42,158) Denominator: Weighted average shares of Class A common stock outstanding—basic 39,237 39,085 37,129 Weighted average shares of Class A common stock outstanding—diluted 39,237 39,085 37,129 Loss per share of Class A common stock—basic $ (0.61) $ (0.22) $ (1.14) Loss per share of Class A common stock—diluted $ (0.61) $ (0.22) $ (1.14) 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. The following table presents potentially dilutive securities excluded from the computations of diluted loss per share of Class A common stock: 2022 2021 2020 Stock options 134,031 (1) 154,231 (1) 489,024 (1) Performance stock units 159,822 (1) 186,159 (1) 137,221 (1) Restricted stock units 395,853 (1) 231,429 (1) 258,493 (1) Shares of Class B common stock 2,869,513 (1) 2,921,587 (1) 2,951,188 (1) Convertible notes 1,466,975 (1) 1,466,975 (1) — (1) Number of securities outstanding at the end of the period that were excluded from the computation of diluted loss per share of Class A common stock because the effect would have been 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. NOTE 2: BASIS OF PRESENTATION 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. Intercompany revenue consists of these reimbursement payments and is recognized when the corresponding expense to which it relates is recognized. Certain intercompany balances presented in these Condensed Parent Company financial statements are eliminated in the Company's Consolidated Financial Statements. The following table presents amounts in the Parent Company's Condensed Balance Sheets that were eliminated in consolidation: December 28 December 29 Assets Due from SSE Holdings $ 2,963 $ 2,035 Deferred income taxes, net 8,004 7,234 Note receivable from SSE Holdings 209,013 201,080 Note receivable - conversion option 6,300 16,000 Liabilities Due to SSE Holdings 16,975 14,109 Related party amounts that were not eliminated in the Company's Consolidated Financial Statements include the Parent Company's liabilities under the tax receivable agreement, which totaled $234,893 and $234,045, respectively as of December 28, 2022 and December 29, 2021.

SSE Holdings promises to pay the Parent Company, for value received, the principal amount with interest of the Intercompany Note in March 2028. The Parent Company 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 the Parent Company and the aggregate number of outstanding shares of Class A common stock. The Parent Company's right to convert the Intercompany Note into common units of SSE Holdings (the "Conversion Option") is required to be bifurcated from the Intercompany Note and shown separately on the Parent Company's Condensed Balance Sheets. The Conversion Option is to be recorded at fair value and remeasured at each subsequent reporting date. On the date of issuance, the Conversion Option was determined to be an asset with a fair value of $48,200. As of December 28, 2022 and December 29, 2021, the fair value of the Conversion Option was $6,300 and $16,000, respectively. The Parent Company recorded unrealized losses of $9,700 and $32,200, respectively in fiscal 2022 and fiscal 2021, within Other income (expense), net due to the change in fair value of the Conversion Option. As of December 28, 2022 and December 29, 2021, the balance of the Note receivable from SSE Holdings was $209,013 and $201,080, respectively, net of accretion. The Parent Company recognized interest income of $7,933 and $6,605, respectively, in fiscal 2022 and fiscal 2021, within Other income (expense), net primarily associated with the accretion of the Conversion Option value at issuance. NOTE 4: DEBT In March 2021, the Parent Company issued $225,000 aggregate principal amount of 0% Convertible Senior Notes due 2028 (“Convertible Notes”) in a private placement to qualified institutional buyers pursuant to Rule 144A under the Securities Act of 1933. The Parent Company granted an option to the initial purchasers to purchase up to an additional $25,000 aggregate principal amount of Convertible Notes to cover over-allotments, which was subsequently fully exercised during March 2021, resulting in a total issuance of $250,000 aggregate principal amount of Convertible Notes. The 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. Refer to Note 8, Debt, in the Company's Consolidated Financial Statements, included in Part II, Item 8, for additional information relating to the Convertible Notes. NOTE 5: COMMITMENTS AND CONTINGENCIES On February 4, 2015, the Parent Company entered into a tax receivable agreement with the non-controlling interest holders that provides for payments to the non-controlling interest holders of 85% of the amount of any tax benefits that the Parent Company actually realizes, or in some cases is deemed to realize, as a result of certain transactions. Refer to Note 14, Income Taxes, to the Company's Consolidated Financial Statements included in Part II, Item 8, for additional information relating to the Parent Company's Tax Receivable Agreement. As described in Note 17, Commitments and Contingencies, to the Company's Consolidated Financial Statements, amounts payable under the Tax Receivable Agreement are contingent upon, among other things, (i) generation of future taxable income of Shake Shack Inc. over the term of the Tax Receivable Agreement and (ii) future changes in tax laws. As of December 28, 2022 and December 29, 2021, liabilities under the tax receivable agreement totaled $234,893 and $234,045, respectively.

SUMMARY OF SIGNIFICANT ACCOUN_2

SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (Policies)	12 Months Ended
	Dec. 28, 2022
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 28, 2022 and December 29, 2021, the net assets of SSE Holdings were $362,571 and $376,857, 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 year 2022 contained 52 weeks and ended on December 28, 2022 ("fiscal 2022"). Fiscal year 2021 contained 52 weeks and ended on December 29, 2021 ("fiscal 2021"). Fiscal year 2020 contained 53 weeks and ended on December 30, 2020 ("fiscal 2020"). 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.
Segment Reporting	Segment Reporting The chief operating decision maker (the "CODM") is the Chief Executive Officer. The Company determined it has one operating segment and one reportable segment, as the CODM regularly reviews Shack operations and financial performance at a consolidated level to allocate resources.
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 consist of mutual funds that primarily invest in corporate bonds, certificates of deposits, asset-backed securities, commercial paper, U.S. Treasury obligations, and foreign government securities. Marketable securities are recorded at fair value, with unrealized gains and losses recorded in Other income (expense), net. Dividend and interest income are recognized when earned and are recorded in Other income (expense), net on the Consolidated Statements of Loss.
Accounts Receivable, Net	Accounts Receivable, NetAccounts 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 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 is 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 Impairment and loss on disposal of assets on the Consolidated Statements of Loss. Valuation of Long-lived Assets
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 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 Loss. As of December 28, 2022 and December 29, 2021, capitalized implementation costs from cloud computing arrangements totaled $6,212 and $6,431, 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 28, 2022 and December 29, 2021, indefinite-lived intangible assets relating to transferable liquor licenses totaled $1,837 and $1,461, respectively. Indefinite-lived intangible assets are evaluated for impairment 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 Revenue primarily consists of Shack sales and Licensing revenue. Generally, revenue is recognized as promised goods or services transfer to the guest or customer in an amount that reflects the consideration the Company expects to be entitled to in exchange for those goods or services. 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. Sales tax collected from guests is excluded from Shack sales and the obligation is included as sales tax payable until the taxes are remitted to the appropriate taxing authorities. Revenue from gift cards is deferred and recognized over time as redemptions occur. Delivery services are fulfilled by third-party delivery partners whether ordered through the Shack app and website ("Company-owned platforms") or though third-party delivery partners. 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 partners 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 order and the payment terms are short-term in nature. For all delivery sales, the Company is considered the principal and recognizes the revenue on a gross basis. During fiscal 2022, the Company concluded it has 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. Accordingly, the Company recognizes breakage income and reduces the related gift card liability for unredeemed gift cards in proportion to actual redemptions of gift cards. The Company will continue to review historical gift card redemption information at each reporting period to assess the continued appropriateness of the gift card breakage rate and pattern of redemption. 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. Inclusive of this cumulative catch-up, $1,472 of gift card breakage income was recognized during fiscal 2022. Gift card breakage income is included in Shack sales in the Consolidated Statements of Loss. 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 is comprised of the initial territory fee and an estimate of the total Shack opening fees the Company expects to be entitled to. The calculation of total Shack opening fees included in the transaction price requires judgment, as it is based on an 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 or upon opening the related Shack. These payments are initially deferred and recognized in revenue as the performance obligations are satisfied, which occurs over a long-term period. 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. 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 Loss.
Leases	Leases Shake Shack currently leases all of its domestic Company-operated Shacks, the home office and certain equipment under various non-cancelable lease agreements that expire on various dates through 2044. 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 benefits 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 and the Company has identified a lease, 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. Lease expense incurred before a Shack opens is recorded in Pre-opening costs on the Consolidated Statements of Loss. Once a domestic Company-operated Shack opens, the straight-line lease expense and contingent rent, if applicable, are recorded in Occupancy and related expenses on the Consolidated Statements of Loss. Many of the 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 on the Consolidated Statements of Loss. 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, is recognized as incurred. For leases with a lease term of 12 months or less ("short-term lease"), any fixed lease payments are recognized on a straight-line basis over such term, and are not recognized on the Consolidated Balance Sheets. The Company calculates operating lease 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, which are also reflected as a reduction to the initial measurement of the 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 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.
