Accounting Policies [Abstract]
DESCRIPTION OF BUSINESS AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES	DESCRIPTION OF BUSINESS AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES Sweetgreen, Inc., a Delaware corporation, together with its wholly owned subsidiaries (the “Company”), is a mission-driven, next generation restaurant and lifestyle brand that serves healthy food at scale. The Company’s bold vision is to be as ubiquitous as traditional fast food, but with the transparency and quality that consumers increasingly expect. As of December 31, 2023, the Company owned and operated 221 restaurants in 18 states and Washington, D.C. The Company had 35 Net New Restaurant Openings in fiscal year 2023. The Company was founded in November 2006 and incorporated in the state of Delaware in October 2009 and currently is headquartered in Los Angeles, California. The Company’s operations are conducted as one operating segment and one reportable segment, as the Company’s chief operating decision maker, who is the Company’s Chief Executive Officer, reviews financial information on an aggregate basis for purposes of allocating resources and evaluating financial performance. The Company’s revenue is derived from retail sales of food and beverages by company-owned restaurants. Initial Public Offering —On November 22, 2021, the Company closed its initial public offering (“IPO”), in which it issued and sold 14,950,000 shares of its Class A common stock at a price per share of $28.00. The Company received net proceeds of approximately $384.7 million from the IPO after deducting underwriting discounts and commis sions of $26.4 million and offering costs of approximately $7.5 million subject to certain cost reimbursements. In connection with the IPO, (i) 69,231,197 outstanding shares of preferred stock were converted into an equivalent number of shares of common stock and (ii) 1,843,493 shares of outstanding Class S stock issued in connection with the Company’s acquisition of Spyce Food Co. (“Spyce”) in September 2021 were converted into 1,316,763 shares of common stock, resulting in an aggregate of 92,754,432 outstanding shares of common stock. These shares were then reclassified into an equivalent number of shares of Class A common stock. Additionally, in connection with the IPO, warrants to purchase 1,557,686 shares of Series J Preferred Stock were automatically exercised for an equivalent number of shares of Class A common stock, and an aggregate of 13,477,303 shares of Class A common stock held by Messrs. Neman, Jammet, and Ru, the Company’s co-founders, were exchanged for an equivalent number of shares of Class B common stock pursuant to the terms of an exchange agreement entered into with the Company. Furthermore, the Series F Warrants, which were exercised during fiscal year 2021, converted into 235,000 shares of Class A common stock. Finally, the Company recognized $14.3 million in other expense in the consolidated statement of operations from the change in fair value of the Series J and Series F warrants, based on the initial public offering price of $28.00 per share, less the underlying exercise price of the warrants and $5.4 million of stock-based compensation expense for options with a performance-based vesting condition satisfied at IPO. Principles of Consolidation —The accompanying consolidated financial statements include the accounts of the Company. All intercompany balances and transactions have been eliminated in consolidation. Fiscal Year —The Company’s fiscal year is a 52- or 53-week period that ends on the last Sunday of the calendar year. Fiscal year 2023 was a 53-week period that ended December 31, 2023. Fiscal years 2022 and 2021 were 52-week periods that ended December 25, 2022 and December 26, 2021, respectively. In a 53-week fiscal year, the first, second and third quarters each include 13 weeks of operations, and the fourth quarter includes 14 weeks of operations. In a 52-week fiscal year, each quarter includes 13 weeks of operations. Management’s Use of Estimates —The consolidated financial statements have been prepared by the Company in accordance with accounting principles generally accepted in the United States of America (“GAAP”) and the rules and regulations of the Securities and Exchange Commission (“SEC”). The preparation of consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect certain reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the consolidated financial statements and the reported amounts of revenues and expenses during the reporting period. Significant accounting estimates made by the Company include the income tax valuation allowance, impairment of long-lived assets and right-of-use assets (“ROU assets”), legal liabilities, valuation of the contingent consideration liability, lease accounting matters, valuation of intangible assets acquired in business combinations, goodwill, and stock-based compensation. These estimates are based on information available as of the date of the consolidated financial statements; therefore, actual results could differ from those estimates. Cash and Cash Equivalents —The Company considers all highly liquid investments with a maturity of three months or less at the time of purchase to be cash equivalents. Amounts receivable from credit card processors are converted to cash shortly after the related sales transaction and are considered to be cash equivalents because they are both short-term and highly liquid in nature. Amounts receivable from sales transactions as of December 31, 2023 and December 25, 2022, were $3.0 million and $0.7 million, respectively. Restricted Cash —The Company’s restricted cash balance relates to certificates of deposit that are collateral for letters of credit to lease agreements entered into by the Company and cash from the Spyce acquisition. See Note 6. The reconciliation of cash and cash equivalents and restricted cash presented in the Company’s accompanying consolidated balance sheets to the total amount shown in its consolidated statements of cash flows is as follows: (dollar amounts in thousands) December 31, December 25, Reconciliation of cash, cash equivalents and restricted cash: Cash and cash equivalents $ 257,230 $ 331,614 Restricted cash, non-current 125 125 Total cash, cash equivalents and restricted cash shown on statement of cash flows $ 257,355 $ 331,739 Concentrations of Risk — The Company maintains cash balances at several financial institutions located in the United States. The cash balances may, at times, exceed federally insured limits. Accounts are guaranteed by the Federal Deposit Insurance Corporation (“FDIC”) up to $0.3 million. As of December 31, 2023, December 25, 2022, and December 26, 2021, approximately 28%, 32%, and 33%, respectively, of the Company’s revenue was generated from the Company’s restaurants located in the New York City metropolitan area. Other Current Assets — Other current assets primarily consist of the Employee Retention Credit “ERC”, outstanding receivables from the Company’s distributors and current amortization of deferred costs. Subsequent to the adoption of ASC 842, other current assets also consist of tenant improvement allowance receivables for locations that have no corresponding operating lease asset and liability due to their rent payments being entirely variable, and amount to $0.8 million and $0.3 million as of December 31, 2023 and December 25, 2022, respectively. Other Assets — Other Assets primarily consist of deferred costs, which are capitalized implementation costs from cloud computing arrangements in relation the Company’s enterprise resource planning system (“ERP”). These costs amounted to $4.2 million and $4.8 million as of December 31, 2023 and December 25, 2022 and were recorded within other assets in the consolidated balance sheets. The amortization of these costs are recognized within the Company’s consolidated statement of operations under general and administrative expenses over a useful life of seven years. Accounts Receivable — Accounts receivable primarily consists of receivables from distributors and receivables from the Company’s Marketplace and Outpost and Catering Channels. Inventory — Inventory, consisting primarily of food, beverages and supplies, is valued at the lower of cost first-in, first-out cost or net realizable value. Prepaid Expenses — Prepaid expenses primarily include prepaid insurance, which is expensed in the period for which it relates. Property and Equipment —Property and equipment are recorded at cost. Property and equipment are depreciated using the straight-line method over the following estimated useful lives: Property and Equipment Useful Life Leasehold improvements Shorter of lease term or estimated asset life Furniture and fixtures 5 years Kitchen equipment 5 years Computers and other equipment 3 years Upon retirement or disposal of assets, the accounts are relieved of cost and accumulated depreciation and any related gain or loss is reflected in loss on disposal of property and equipment in the consolidated statement of operations. Assets to be disposed consists of primarily furniture, equipment and fixtures that were replaced in the normal course of business and are reported at the lower of their carrying amount or fair value less estimated cost to sell. Expenditures for repairs and maintenance are charged directly to expense when incurred. The cost of assets sold, retired, or otherwise disposed of, and the related accumulated depreciation and amortization are eliminated from the accounts, and any resulting gain or loss is included in earnings. The Company capitalizes certain directly attributable internal costs in conjunction with the acquisition, development and construction of future restaurants, after the restaurant construction is past the planning stage and it is considered probable that the restaurant will open. These costs are included in property and equipment and amortized over the shorter of the life of the related buildings and leasehold improvements or the lease term. Costs related to abandoned sites and other site selection costs that cannot be identified with specific restaurants are charged to general and administrative expenses in the accompanying consolidated statements of operations, and were $0.3 million, $0.9 million and $1.2 million for each of the fiscal years ended December 31, 2023, December 25, 2022 and December 26, 2021, respectively. The Company capitalized internal costs related to site selection and construction activities of $4.7 million and $4.0 million for the fiscal years ended December 31, 2023 and December 25, 2022, respectively. In addition, for fiscal year 2022, the Company recorded $0.6 million of costs related to abandoning certain potential future restaurant sites in an effort to streamline the Company’s future new restaurant openings which is recorded within restructuring charges. Restructuring Charges — Restructuring charges are expenses that are paid in connection with reorganization of the Company’s operations during fiscal year 2022. Additionally, in conjunction with the Company’s implementation of ASC Topic 842 (“ASC 842”), operating lease assets were evaluated for impairment, and any impairment charges incurred in conjunction with the Company’s restructuring was considered a restructuring charge. For fiscal year 2022, the Company incurred total pre-tax restructuring and related charges of approximately $14.4 million. This included a $13.0 million non-cash restructuring expense, due to a reduction of the Company’s real estate footprint by vacating the premises of the Company’s existing Sweetgreen Support Center and moving to a smaller office space adjacent to the existing location, of which $6.8 million related to impairment of long-lived assets and $5.8 million and $0.4 million related to impairment of the Company’s operating lease asset and closure costs, respectively, associated with the Sweetgreen Support Center, $0.6 million of severance and related benefits from workforce reductions affecting approximately 5% of employees at the Sweetgreen Support Center, $0.6 million of costs related to abandoning certain potential future restaurant sites in an effort to streamline the Company’s future new restaurant openings, and $0.2 million of other related expenses. For fiscal year 2023 , stemming from the 2022 reorganization, the Company recorded restructuring charges of $7.4 million primarily related to operating lease asset impairment costs from the Company’s vacated former Sweetgreen Support Center as well as the amortization of the underlying operating lease asset and related real estate and common area maintenance fees (“CAM”) charges. Business Combinations —The Company utilizes the acquisition method of accounting in any acquisitions or business combinations. The acquisition method of accounting requires companies to assign values to assets and liabilities acquired based upon their fair values at the acquisition date. In most instances, there are not readily defined or listed market prices for individual assets and liabilities acquired in connection with a business, including intangible assets. The determination of fair value for assets and liabilities in many instances requires a high degree of estimation. The valuation of intangible assets, in particular, is very subjective. The Company generally obtains third-party valuations to assist it in estimating fair values. The use of different valuation techniques and assumptions could change the amounts and useful lives assigned to the assets and liabilities acquired and related amortization expense. Total research and development excluding any related cost associated with the Spyce acquisition was $1.2 million and $2.0 million for the fiscal years ended December 31, 2023 and December 25, 2022, respectively. These costs are recorded within general and administrative cost in the Company’s accompanying consolidated statement of operations. Contingent Consideration —Due to certain conversion features, the contingent consideration issued as part of the Spyce acquisition (see Note 6 for further details) is considered a liability in accordance with ASC 480. The liability associated with the contingent consideration is initially recorded at fair value (see Note 3 for further details) upon issuance date and is subsequently re-measured to fair value at each reporting date. The initial fair value of the liability for the contingent consideration was $16.4 million and was included as part of the purchase price for the Spyce acquisition. The fair value of the liability as of December 31, 2023 and December 25, 2022 was $8.4 million and $21.3 million, respectively. During fiscal year ended December 31, 2023, the Company paid $10.4 million of the contingent consideration. See Note 3. Changes in fair value of the contingent consideration is recognized within other expense in the accompanying consolidated statement of operations. Other Current Liabilities —The other current liabilities is solely comprised of the short-term portion of the contingent consideration liability which was determined based on known stock price values in January 2024. See Note 17. Goodwill —Goodwill, which represents the excess of the cost of an acquired entity over the fair value of the acquired net assets, has an indefinite life and, accordingly, is not amortized. The Company has one reporting unit. The Company tests goodwill for impairment annually, or more frequently if events or changes in circumstances indicate that the asset may be impaired. The Company reviews goodwill for impairment utilizing either a qualitative assessment or a fair value test by comparing the fair value of its reporting unit with its carrying amount. If the Company decides that it is appropriate to perform a qualitative assessment and concludes that the fair value of its reporting unit more likely than not exceeds its carrying value, no further evaluation is necessary. If the Company performs the fair value test, the Company will compare the fair value of a reporting unit with its carrying amount, including goodwill. If the fair value of a reporting unit exceeds its carrying amount, goodwill of the reporting unit is considered not impaired. If the carrying amount of a reporting unit exceeds its fair value, the Company will recognize an impairment charge for the amount by which the carrying amount exceeds its reporting unit’s fair value. The Company performed the qualitative assessment above and concluded that the fair value of the reporting unit is more likely than not to exceed the carrying value, and did not record any impairment charges related to the carrying amount of goodwill during the fiscal years ended December 31, 2023, December 25, 2022, and December 26, 2021. Fair value estimates are subject to change as a result of many factors, including changes in business plans, economic conditions, and the competitive environment, among others. Should actual cash flows and the Company’s future estimates vary adversely from current estimates, the Company may be required to recognize goodwill impairment charges in future years. Intangible Assets, net — External costs and certain internal costs, including payroll and payroll-related costs for employees, directly associated with developing computer software applications for internal use are capitalized subsequent to the preliminary stage of development. Internal-use software costs are amortized using the straight-line method over a three-year estimated useful life of the software when the project is substantially complete and ready for its intended use. Lease Acquisition Costs —Prior to the adoption of ASC 842, lease acquisition costs included key money and legal and broker fees incurred to obtain a lease. Key money is the amount of funds paid to a landlord or tenant to acquire the rights of tenancy under a commercial property lease. These costs were amortized over the respective lease terms that range from 10 to 15 years and are presented net of accumulated amortization. Amortization expense for the fiscal year ended December 26, 2021 was $0.4 million, of which all but an insignificant amount was included in occupancy and related expenses and the remainder was included in general and administrative expenses in the accompanying consolidated statement of operations. Upon adoption of ASC 842, lease acquisition costs associated with legal and broker fees are expensed as incurred and no longer capitalized. As such, lease acquisition costs only include key money. Total lease acquisition costs, net of accumulated amortization, as of December 31, 2023 and December 25, 2022 were $0.5 million and $0.6 million, respectively. Amortization expense for both the fiscal years ended December 31, 2023 and December 25, 2022 was $0.1 million, which was recorded within occupancy and related expenses in the accompanying statement of operations. Further, the Company recorded $1.7 million of legal fee expenses associated with obtaining a lease for the fiscal year ended December 25, 2022 which was recorded to general and administrative expenses within the consolidated statement of operations. The Company also recorded a $4.2 million adjustment to accumulated deficit as of the effective date of the adoption of ASC 842, related to legal fees no longer capitalizable. See Note 9. Revenue Recognition —The Company recognizes food and beverage revenue, net of discounts and incentives, when payment is tendered at the point of sale as the performance obligation has been satisfied, through the Company’s three disaggregated revenue channels: Owned Digital Channels, In Store-Channel (Non-Digital component), and Marketplace Channel. Owned Digital Channels encompasses the Company’s Pick-Up Channel, Native Delivery Channel, Outpost and Catering Channel, and purchases made in its In-Store Channel via digital scan-to-pay, prior to the elimination of digital scan-to-pay during the fiscal quarter ended September 24, 2023. Pick-Up Channel refers to sales to customers made for pick-up at one of the Company’s restaurants through the Sweetgreen website or mobile app. Native Delivery Channel refers to sales to customers for delivery made through the Sweetgreen website or mobile app. Outpost and Catering Channel refers to sales to customers for delivery made through the Sweetgreen website or mobile app to Outposts, which are the Company’s offsite drop-off points at offices, residential buildings and hospitals. In addition, the Company’s Outpost and Catering Channel includes the Company’s catering offerings, which refer to sales to customers made through the Company’s catering website for pickup at one of the Company’s restaurants or delivery to a customer-specified address. In-Store Channel (Non-Digital component) refers to sales to customers who make in-store purchases in the Company’s restaurants, whether they pay by cash or credit card, or digital scan-to-pay. Digital scan-to-pay was eliminated during the fiscal quarter ended September 24, 2023. Purchases made in the Company’s In-Store Channel via cash or credit card are referred to as “Non-Digital” transactions, and purchases made in the Company’s In-Store Channel via digital scan-to-pay, prior to its elimination, were included as part of the Company’s Owned Digital Channels. Marketplace Channel refers to sales to customers for delivery or pick-up made through third-party delivery marketplaces, including DoorDash, Grubhub, Uber Eats, ezCater, Sharebite and others. Provisions for discounts are provided for in the same period the related sales are recorded. Sales taxes and other taxes collected from customers and remitted to governmental authorities are presented on a net basis, and as such, are excluded from revenues. Gift Cards —The Company sells gift cards that do not have an expiration date. Upon sale, gift cards are recorded as unearned revenue and included within gift card liability in the accompanying consolidated balance sheets. The revenue from gift cards is recognized when redeemed by customers. Because the Company does not track addresses of gift card purchasers, the relevant jurisdiction related to the requirement for escheatment, the legal obligation to remit unclaimed assets to the state, is the Company’s state of incorporation, which is Delaware. The state of Delaware requires escheatment after 5 years from issuance. The Company does not recognize breakage income because of its requirements to escheat unredeemed gift card balances. Delivery —The majority of the Company’s restaurant locations offer a delivery option. Delivery services are fulfilled by third-party service providers whether delivery is ordered through the Company’s Native Delivery Channel or Marketplace Channel. With respect to Native Delivery sales, the Company controls the delivery services and recognizes revenue, including delivery revenue, when the delivery partner transfers food or beverage to the customer. For these sales, the Company receives payment directly from the customer at the time of sale. With respect to Marketplace Channel sales, the Company recognizes revenue, excluding delivery fees collected by the delivery partner as the Company does not control the delivery service, when control of the food is delivered to the end customer. The Company receives payment from the delivery partner subsequent to the transfer of food and the payment terms are short-term in nature. For all delivery sales, the Company is considered the principal and recognize the revenue on a gross basis. Income Taxes —The Company is subject to federal and state income taxes. The Company uses the asset and liability method of accounting for income taxes as set forth in ASC 740, Income Taxes . Under this method, the Company recognizes deferred tax assets and liabilities for the expected future tax consequences of temporary differences between the respective carrying amounts and tax basis of assets and liabilities. All deferred tax assets and liabilities are classified as non-current in the accompanying consolidated balance sheet. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in income in the period that includes the enactment date. A valuation allowance is established against the portion of deferred tax assets that the Company believes will not be realized on a more-likely-than-not basis. With respect to uncertain tax positions, the Company recognizes in its consolidated financial statements those tax positions determined to be “more likely than not” of being sustained upon examination, based on the technical merits of the positions. For those tax positions where it is “not more likely than not” that a tax benefit will be sustained, no tax benefit is recognized. The Company’s policy is to recognize, when applicable, interest and penalties on uncertain tax positions as part of income tax expense. Fair Value of Financial Instruments —The fair value measurement accounting guidance creates a fair value hierarchy to prioritize the inputs used to measure fair value into three categories. A financial instrument’s level within the fair value hierarchy is based on the lowest level of input significant to the fair value measurement, where Level 1 is the highest category (observable inputs) and Level 3 is the lowest category (unobservable inputs). The three levels are defined as follows: Level 1 —Quoted prices for identical instruments in active markets. Level 2 —Quoted prices for similar instruments in active markets, quoted prices for identical or similar instruments in markets that are not active and model-derived valuations in which significant value drivers are observable. Level 3 —Unobservable inputs for the asset or liability. This includes certain pricing models, discounted cash flow methodologies and similar techniques that use significant unobservable inputs. The carrying amount of accounts receivable, other current assets, accounts payable, accrued payroll and accrued expenses approximates fair value due to the short-term maturity of these financial instruments. The Company’s contingent consideration liability is carried at fair value determined using Level 3 inputs in the fair value. See Note 3. Certain assets and liabilities are measured at fair value on a nonrecurring basis. In other words, the instruments are not measured at fair value on an ongoing basis but are subject to fair value adjustments only in certain circumstances (for example, when there is evidence of impairment). See Note 3. Impairment and Closure Costs — Impairment includes impairment charges related to our long-lived assets, which include property and equipment and internally developed software, and subsequent to the adoption of ASC 842, operating lease assets. Long-lived assets are reviewed for recoverability at the lowest level in which there are identifiable cash flows (“asset group”). The asset group is at the store-level for restaurant assets and the corporate-level for corporate assets. The carrying amount of a store asset group includes stores’ property and equipment, primarily leasehold improvements, and operating lease assets, net of operating lease liability. The carrying amount of a corporate-level asset group includes support center property and equipment, operating lease assets, internally developed software and internally developed technology. Long-lived assets are reviewed by management for impairment whenever events or changes in circumstances indicate that the carrying amount of the asset may not be fully recoverable. When events or circumstances indicate that impairment may be present, management evaluates the probability that future undiscounted net cash flows received will be less than the carrying amount of the asset group. If projected future undiscounted cash flows are less than the carrying value of an asset group, then such assets are written down to their fair values. The Company uses a discounted cash flow model to measure the fair value of an asset group. An impairment charge will be recognized in the amount by which the carrying amount of the store asset group exceeds its fair value. The resulting impairment charge, if any, is allocated to the property and equipment, primarily leasehold improvements, and operating lease assets on a pro rata basis using the relative carrying amounts of those assets. The allocated impairment charge to a long-lived asset is limited to the extent that the impairment charge does not reduce the carrying amount of the long-lived asset below its individual fair value. The estimation of the fair value of an operating lease asset primarily involves the evaluation of current and future market value rental amounts, which are primarily based on recent observable market rental data. The fair value of an operating lease asset is measured using a discounted cash flow valuation technique by discounting the estimated current and future market rental values using a property-specific discount rate. A number of significant assumptions and estimates are involved in the application of the model to forecast operating cash flows, which are largely unobservable inputs, including future revenue projections. Accordingly, such significant assumptions are classified as Level 3 inputs within the fair value hierarchy. Assumptions used in these forecasts are consistent with internal planning, and include sales growth rates, gross margins, and operating expense in relation to the current economic environment and the Company’s future expectations, competitive factors in its various markets, inflation, sales trends and other relevant economic factors that may impact the store under evaluation. In addition, assumptions used for operating lease assets vacated for future sublease include the Company’s estimated future sublease income and a property specific discount rate. There is uncertainty in the projected undiscounted future cash flows used in the Company’s impairment review analysis, which requires the use of estimates and assumptions. If actual performance does not achieve the projections, or if the assumptions used change in the future, the Company may be required to recognize impairment charges in future periods, and such charges could be material. The Company determined that triggering events, primarily related to the impact of changing customer behavior trends, including slower than expected return to office during and following the COVID-19 pandemic (including as a result of many workplaces adopting remote or hybrid models) and as a result of broader macroeconomic conditions on the Company’s near-term restaurant level cash flow forecast, restructuring activities and anticipated store closures, occurred for certain restaurants and its Support Center, that required an impairment review of the Company’s long-lived assets. No indicators of impairment were found for the Company’s intangible assets for the fiscal years ended December 31, 2023, December 25, 2022, and December 26, 2021. Based on the results of this analysis, the Company recorded non-cash impairment charges of $4.3 million during the fiscal year ended December 31, 2023, related to the operating lease asset for the Company’s former Sweetgreen Support Center vacated previously during fiscal year 2022, which was recorded under restructuring charges restructuring charges restructuring charges impairment and closure costs restructuring charges impairment and closure costs operations. During the fiscal year ended December 26, 2021, the Company recorded non-cash impairment charges of $4.4 million, related to certain of the Company’s stores, as well as the two stores operated by Spyce Food Co. (“Spyce”). Prior to the adoption of ASC 842, closure costs included non-cash restaurant charges such as up-front expensing the net present value of unpaid rent remaining on the life of a lease offset by assumed sublease income. Subsequent to the adoption of ASC 842, closure costs include lease and related costs associated with closed restaurants including the amortization of the operating lease asset, and expenses associated with common area maintenance fees and real estate taxes for previously impaired stores. During the fiscal year ended December 31, 2023, the Company recognized closure costs of $0.6 million related to the amortization of the operating lease asset and expenses associated with CAM and real estate taxes for previously closed stores, including three previously impaired stores that were

The following table presents the Company’s revenue for the fiscal years ended December 31, 2023, December 25, 2022 and December 26, 2021 disaggregated by significant revenue channel: (dollar amounts in thousands) December 31, 2023 December 25, 2022 December 26, 2021 Owned Digital Channels $ 212,872 $ 191,129 $ 156,513 In-Store Channel (Non-Digital component) 242,073 177,996 110,850 Marketplace Channel 129,096 100,980 72,511 Total Revenue $ 584,041 $ 470,105 $ 339,874 Gift Cards Gift card liability included in gift card within the accompanying consolidated balance sheet was as follows: (dollar amounts in thousands) December 31, December 25, December 26, 2021 Gift Card Liability $ 2,797 $ 2,016 $ 1,839 Revenue recognized from the redemption of gift cards that was included in gift card and loyalty liability at the beginning of the year was as follows: (dollar amounts in thousands) Fiscal Year Ended December 31, 2023 Fiscal Year Ended December 25, 2022 Fiscal Year Ended December 26, 2021 Revenue recognized from gift card liability balance at the beginning of the year $ 480 $ 378 $ 244 Sweetpass During the second quarter of fiscal 2023, the Company launched its Sweetpass and Sweetpass + loyalty program nationwide. Prior to the introduction of Sweetpass, t he Company had a loyalty program called Sweetgreen Rewards, which was terminated during fiscal year 2021 and all revenue related to performance obligations for Sweetgreen Rewards was satisfied as of December 26, 2021. Sweetpass is the Company’s loyalty program where customers can earn rewards, birthday treats, menu exclusives and more. All customers that create a digital account will automatically be enrolled in this free program. For additional perks like a daily $3 off, customers can upgrade to Sweetpass+ for $10 per month. In both the Sweetpass and Sweetpass + program, customers can earn rewards for completing challenges which are generally earned by customers when they purchase certain goods within established time periods of one to two weeks. (“Rewards”). The Rewards generally provide customers with future discounts or free goods, and typically expire within one week to two weeks after they are issued. The Company defers revenue associated with the estimated standalone selling price of the Rewards, which is based on the value of the product to which the reward is related to and incorporates the estimate of the likelihood that the Rewards will be redeemed. The Rewards are recognized as revenue when the customer redeems the Rewards or it expires. Due to the insignificant nature of outstanding Rewards as of December 31, 2023, no revenue was deferred for the fiscal year ended December 31, 2023 related to the Rewards. The costs associated with Rewards redeemed are primarily included within food, beverage and packaging costs.

Fair Value Disclosures [Abstract]
FAIR VALUE	FAIR VALUE The following tables present information about the Company’s financial liabilities measured at fair value on a recurring basis: Fair Value Measurements as of December 31, 2023 Fair Value Measurements as of December 25, 2022 Total Level 1 Level 2 Level 3 Total Level 1 Level 2 Level 3 (dollar amounts in thousands) Contingent consideration $ 8,350 — — 8,350 $ 21,296 — — 21,296 The fair value of the contingent consideration was determined based on significant inputs not observable in the market. Contingent Consideration In connection with the Company’s acquisition of Spyce on September 7, 2021, the former equity holders of Spyce may receive up to 714,285 additional shares of Class A common stock, calculated based on the initial offering price of the Company’s Class A common stock of $28.00 per share sold in the Company’s initial public offering (“IPO”) (the “Reference Price”), contingent on the achievement of certain performance milestones between the closing date of the acquisition and June 30, 2026 . See Note 6. Add itionally, the former equity holders of Spyce may receive true-up payments in cash, as described here. If as of the second anniversary of the closing date of the acquisition, the 30-Day Volume-Weighted Average Price of the Company’s Class A common stock (“VWAP Price”) is less than the Reference Price, then the Company shall pay to each former equity holder of Spyce that has continually held their respective portion of the 1,316,763 total shares of the Company’s Class A common stock issued in connection with the acquisition during such period, the delta between the Reference Price and the VWAP Price for the upfront portion of the purchase price (“true-up payment”). As of the second anniversary of the closing date of the acquisition, the Company calculated the delta between the Reference Price and the VWAP Price for the upfront portion of the purchase price as $13.62. This resulted in a true-up payment of $10.4 million, due to 570,249 shares that did not meet the continuous holding requirement. The $10.4 million true-up payment is included within financing in the Consolidated Statements of Cash Flows as the payment is less than the original fair value of contingent consideration. Additionally, if as of the date of the achievement of any of the three milestones, the VWAP Price as of such milestone achievement date is less than the Reference Price, then the Company shall pay to each former equity holder of Spyce that is eligible to receive a milestone payment the delta between the Reference Price and the VWAP Price for the contingent consideration associated with such milestone. The contingent consideration, excluding the true-up payment, which was calculated as noted above, was valued using the Monte Carlo method. The analysis considered, among other items, the equity value, the contractual terms of the Spyce merger agreement, potential liquidity event scenarios (prior to the IPO), the Company’s credit-adjusted discount rate, equity volatility, risk-free rate, and the probability that milestone targets required for issuance of shares under the contingent consideration will be achieved. During the fourth quarter of fiscal 2023, the first milestone was achieved, which resulted in former equity holders of Spyce being eligible to receive $6.0 million, which was issued and paid subsequent to December 31, 2023 . Of this $6.0 million, $2.1 million was issued in Class A common stock and $3.9 million was issued in cash, based on a VWAP Price of $10.20. As the stock was issued and payment was made within one year from December 31, 2023, it was included in other current liabilities within the Consolidated Balance Sheets. The following table provides a roll forward of the aggregate fair values of the Company’s contingent consideration, for which fair value is determined using Level 3 inputs.

Business Combination and Asset Acquisition [Abstract]
BUSINESS ACQUISITION	BUSINESS ACQUISITION On September 7, 2021, the Company closed its acquisition of Spyce, a Boston-based restaurant company powered by automation technology. The Company acquired 100% of the stock of Spyce via a merger. The purpose of the acquisition is to allow the Company to serve its food with even better quality, consistency and efficiency in its restaurants via automation. Pursuant to the merger agreement, upon closing of the acquisition, the Company issued 1,843,493 shares of Class S stock (the “Class S Shares”) worth approximately $37.5 million, of which $6.8 million is considered post-business combination compensation expense, see Note 12 for details, and subject to certain vesting requirements of certain Spyce employees. In connection with the Company’s IPO, the Class S Shares converted into 1,316,763 shares of common stock pursuant to a formula based on the Reference Price, which such shares were then reclassified into shares of Class A common stock. Additionally, the Company paid off approximately $3.5 million of certain indebtedness and transaction expenses of Spyce. Furthermore, the former equity holders of Spyce may receive up to an aggregate of 714,285 additional shares of Class A common stock contingent on the achievement of certain performance milestones between the closing date and June 30, 2026.

Debt Disclosure [Abstract]
DEBT	DEBT Credit Facility —On December 14, 2020, the Company entered into a First Amended and Restated Revolving Credit, Delayed Draw Term Loan and Security Agreement (as subsequently amended, as discussed below, the “2020 Credit Facility”) with EagleBank. The 2020 Credit Facility superseded the Company’s 2017 revolving credit facility with EagleBank and allows the Company to borrow (i) up to $35.0 million (subsequently increased to $45.0 million) in the aggregate principal amount under the refinanced revolving facility and (ii) up to $10.0 million in the aggregate principal amount under a delayed draw term loan facility, which expired on December 14, 2021, and which was never drawn on. The refinanced revolving facility originally matured on December 14, 2022 (and has since been extended to December 13, 2024). However, if the Company issues certain convertible debt or unsecured indebtedness under the 2020 Credit Facility, then the refinanced revolving facility will mature on the earlier to occur of (i) the maturity date indicated in the previous sentence and (ii) 90 days prior to the scheduled maturity date for any portion of such permitted convertible debt or unsecured indebtedness. On May 9, 2022, the Company and Eagle Bank amended the 2020 Credit Facility to allow for the issuance of letters of credit of up to $1.5 million under the revolving facility. In connection therewith, EagleBank issued a $950,000 irrevocable standby Letter of Credit to the Company with The Travelers Indemnity Company as the beneficiary in connection with the Company’s workers compensation insurance policy. On December 13, 2022, the Company and Eagle Bank amended the 2020 Credit Facility to extend the maturity date from December 14, 2022 to December 13, 2024. The 2020 Credit Facility also increased the revolving facility cap by $10.0 million, to allow for the Company to borrow up to $45.0 million in the aggregate principal amount under the refinanced revolving facility. The Company incurred $0.1 million of loan origination fees related to the amendment, which was recorded within other current assets on the audited consolidated balance sheets and will be amortized over the life of the facility. Under the 2020 Credit Facility, interest accrues on the outstanding loan balance and is payable monthly at a rate of the adjusted one-month term Secured Overnight Financing Rate, plus 2.90%, with a floor on the interest rate at 3.75%. As of December 31, 2023 and December 25, 2022, the Company had no outstanding balance under the 2020 Credit Facility. On April 26, 2023, the Company and Eagle Bank further amended the 2020 Credit Facility to allow for an increase to the issuance of Letters of Credit of up to $3.5 million. In connection therewith, the Company increased its irrevocable standby Letter of Credit with Eagle Bank to $1.95 million, with The Travelers Indemnity Company as the beneficiary in connection with the Company’s workers’ compensation insurance policy. This replaced the previous amendment dated May 9, 2022. Under the 2020 Credit Facility, the Company is required to maintain certain levels of liquidity (defined as total cash and cash equivalents on hand plus the available amount under the revolving facility) which liquidity amount shall be no less than the trailing 90-day cash burn. The Company was in compliance with the applicable financial covenants as of December 31, 2023 and December 25, 2022. The obligations under the 2020 Credit Facility are guaranteed by the Company’s existing and future material subsidiaries and secured by substantially all of the Company’s and subsidiaries guarantor’s assets. The 2020 Credit Facility also restricts the Company’s ability, and the ability of the Company’s subsidiary guarantors, to, among other things, incur liens; incur additional indebtedness; transfer or dispose of assets; make acquisitions, change the nature of the business; guarantee obligations; pay dividends to shareholders or repurchase stock; and make advances, loans, or other investments. The 2020 Credit Facility contains customary events of default, including, without limitation, failure to pay the outstanding loans or accrued interest on the due date. The Company had unamortized loan origination fees of $0.1 million and $0.1 million as of December 31, 2023 and December 25, 2022, respectively, which are included within the accompanying consolidated balance sheet in other current assets. The Company recognized $0.1 million of interest expense in both fiscal years 2023 and 2022, respectively, related to the amortization of loan origination fees.

Leases [Abstract]
LEASES	LEASES On December 25, 2022 the Company adopted ASU 2016-02, Leases (“ASC 842”), using a modified retrospective approach under the effective date method. The Company did not elect the package of practical expedients permitted under the transition guidance within ASC 842 which, among other items, required the Company to re-evaluate historical lease classifications and determine if previously classified initial direct costs would qualify for capitalization under ASC 842. As a result, the Company recorded a $4.9 million cumulative-effect adjustment to accumulated deficit, of which $4.2 million was related to legal fees no longer capitalizable under ASC 842 and $0.7 million was related to operating lease asset impairment of stores determined to be impaired in a prior period. In addition to the items mentioned above, the Company elected the following: • Adopt the short-term lease exception for leases with terms of twelve months or less and account for them as if they were operating leases under ASC 840; and • Apply the practical expedient of combining lease and non-lease components. Results for reporting periods beginning on or after December 27, 2021 are presented under ASC 842. Prior period amounts were not revised and continue to be reported in accordance with ASC 840, the accounting standard then in effect. The components of lease cost for the fiscal years ended December 31, 2023 and December 25, 2022 were as follows: (dollar amounts in thousands) Classification December 31, December 25, Operating lease cost Occupancy and related expense 48,168 43,722 Variable lease cost Occupancy and related expense 11,055 7,958 Short term lease cost Occupancy and related expense 422 145 Sublease income General and administrative expense (356) (711) Total lease cost $ 59,289 $ 51,114 During the fiscal year ended December 31, 2023, the Company recorded non-cash impairment charges related to operating lease assets of $4.3 million, all of which is recorded within restructuring charges restructuring charges impairment and closure costs As of December 31, 2023, future minimum lease payments for operating leases consisted of the following: (dollar amounts in thousands) 2024 50,658 2025 55,656 2026 54,582 2027 50,363 2028 44,248 Thereafter 138,292 Total 393,799 Less: imputed interest 90,934 Total lease liabilities 302,865 As of December 31, 2023 the Company had additional operating lease commitments of $25.9 million for non-cancelable leases without a possession date, which the Company anticipates will commence in fiscal year 2024. The nature of such lease commitments is consistent with the nature of the leases that the Company has executed thus far. A summary of lease terms and discount rates for operating leases as of December 31, 2023 and December 25, 2022 is as follows: December 31, December 25, Weighted average remaining lease term (years): Operating Leases 7.41 7.98 Weighted average discount rate: Operating Leases 6.51 % 6.09 % Supplemental cash flow information related to leases as of December 31, 2023 and December 25, 2022 is as follows: December 31, December 25, Cash paid for amounts included in the measurement of lease liabilities: Operating cash flows from operating leases, net of lease incentives $ 42,425 $ 29,230 Right of use assets obtained in exchange for lease obligations: Operating leases $ 24,416 $ 57,396 Prior to the adoption of ASC 842, the fiscal years ended December 26, 2021 were in accordance with ASC 840.

Equity [Abstract]
COMMON STOCK	COMMON STOCK In November 2021 in connection with the IPO, the Company implemented a dual class common stock structure pursuant to which all the then-outstanding shares of its common stock were reclassified as Class A common stock and a new class of Class B common stock was authorized. In connection with the IPO, an aggregate of 13,477,303 shares of Class A common stock held by the Company’s founders were exchanged for an equivalent number of Class B common stock. The Class A common stock is entitled to one vote per share and the Class B common stock is entitled to 10 votes per share. The Class A and Class B common stock have the same dividend and liquidation rights. Any founder’s shares of Class B common stock will convert automatically into Class A common stock, on a one-to-one basis, upon either the (i) the sale or transfer of such share of Class B common stock (except for certain permitted transfers described in the Company’s amended and restated certificate of incorporation, including transfers for tax and estate planning purposes or to any other founder or any affiliate of any founder) or (ii) the one-year anniversary of the death or permanent disability of such founder. Additionally, all outstanding shares of the Company’s Class B common stock will convert automatically into shares of the Company’s Class A common stock on the final conversion date, defined as the earlier of (i) the nine-month anniversary of the death or permanent disability of the last of the founders; (ii) the last trading day of the fiscal year during which the 10th anniversary of the effectiveness of the registration statement for the Company’s IPO occurs, and (iii) the date specified by a vote of the holders of a majority of the outstanding shares of Class B common stock; provided, however, that the final conversion date may be extended by the affirmative vote of the holders of the majority of the voting power of the then-outstanding shares of Class A common stock not held by a founder or an affiliate or permitted transferee of a founder and entitled to vote generally in the election of directors, voting together as a single class.

In connection with the Series J Financing, the Company issued certain warrants to purchase shares of the Series J Preferred Stock to the purchasers in the Series J Financing (collectively, the “Series J Warrants”). The Series J Warrants were exercisable for a number of shares based on the fair market value of the Series J Preferred Stock at the time of exercise, up to a maximum of 2,000,715 shares of Series J Preferred Stock (as adjusted for any stock split, stock dividend, combination, or other recapitalization or reclassification) in the aggregate. Warrants”). Both the Series J Warrants and Series F Warrants were determined to be classified as a liability on the consolidated balance sheet because the warrants are free standing financial instruments that may require the Company to transfer assets upon exercise. $4.95 million and remaining proceeds, net of issuance cost, was recorded as an increase to preferred stock on the consolidated statements of preferred stock and stockholders’ deficit. Upon the IPO, t he fair value of the Series J and Series F warrant liability was calculated as the IPO price of $28.00 per share, less the exercise price of each respective warrant, multiplied by the number of warrants exercised. The value of the warrant liability was then reclassified into APIC. In connection with the IPO, all shares of the Company’s outstanding preferred stock automatically converted into 69,231,197 shares of common stock, which were subsequently reclassified as Class A common stock. Additionally, the Series J Warrants were automatically exercised upon the IPO for 1,557,686 shares of Class A common stock and the Series F Warrants were exercised during fiscal year 2021 and converted into 235,000

Share-Based Payment Arrangement [Abstract]
STOCK - BASED COMPENSATION	STOCK-BASED COMPENSATION 2021 Equity Incentive Plan In connection with the Company’s IPO, the Company adopted the 2021 Equity Incentive Plan (the “2021 Plan”), which allows for issuance of stock options (including incentive stock options and non-qualified stock options), restricted stock units (“RSUs”), including performance-based awards, and other types of awards. The maximum number of shares of common stock that may be issued under the 2021 Plan is 35,166,753, which is the sum of (i) 11,500,000 new shares, plus (ii) an additional number of shares consisting of (a) shares that were available for the issuance of awards under any prior equity incentive plans in place (which shall include the Prior Stock Plans (as defined below) and the Spyce Plan (as defined below)) prior to the time the Company’s 2021 Plan became effective and (b) any shares of the Company’s common stock subject to outstanding stock options or other stock awards granted under the Prior Stock Plans that on or after the Company’s 2021 Plan became effective, terminate or expire prior to the exercise or settlement; are not issued because the award is settled in cash; are forfeited because of the failure to vest; or are reacquired or withheld (or not issued) to satisfy a tax withholding obligation or the purchase or exercise price. The total number of shares available for grant as of December 31, 2023 , was 10,572,899 . Options granted generally have vesting terms between twelve months and four years and have a contractual life of 10 years. The Company issues shares of Class A common stock upon the vesting and settlement of RSUs and upon the exercises of stock options under the 2021 Plan. The 2021 Plan is administered by the board of directors, or a duly authorized committee of the Company’s board of directors. Options granted to members of the Company’s board of directors generally vest immediately. 2009 Stock Plan and 2019 Equity Incentive Plan Prior to the Company’s IPO, the Company granted stock options, RSUs and performance-based restricted stock awards (“PSUs”) to its employees, as well as nonemployees (including directors and others who provide substantial services to the Company) under the Company’s 2009 Stock Plan and 2019 Equity Incentive Plan (collectively, the “Prior Stock Plans”). Awards permitted to be granted under the Prior Stock Plans include incentive stock options to the Company’s employees and non-qualified stock options to the Company’s employees and non-employees, as well as stock appreciation rights, restricted stock awards, RSUs (including PSUs), and other forms of stock awards to the Company’s employees, directors and consultants and any of the Company’s affiliated employees and consultants. Options granted in the fiscal year ended December 26, 2021 generally have vesting terms between one year and four years and have a contractual life of 10 years. No further stock awards will be granted under the Prior Stock Plans now that the 2021 Equity Incentive Plan is effective; however, awards outstanding under the Prior Stock Plans will continue to be governed by their existing terms. Spyce Acquisition In conjunction with the Spyce acquisition, the Company issued shares of Class S stock which converted to the Class A common stock upon the Company’s IPO. See Note 6. Shares of Class S stock that were issued to certain Spyce employees, and the corresponding shares of Class A common stock received by such employees in connection with the Company’s IPO, are subject to time-based service requirements and vested on September 7, 2023, as these requirements were met. As the value is fixed, the grant date fair value of these shares represents the fair value of the shares on the acquisition date. For the fiscal years ended December 31, 2023 and December 25, 2022 , the Company recognized stock-based compensation expense of $2.4 million and $3.4 million, respectively, related to the vested portion of such shares. 2021 Employee Stock Purchase Plan In conjunction with the IPO, the Company’s board of directors adopted, and the Company’s stockholders approved the Company’s 2021 employee stock purchase plan (the “ESPP”). The Company’s ESPP authorizes the issuance of 3,000,000 shares of common stock under purchase rights granted to the Company’s employees or to the employees of any of its designated affiliates. The number of shares of the Company’s common stock reserved for issuance will automatically increase on January 1 of each year for a period of 10 years, beginning January 1, 2023, by the lesser of (i) 1% of the total number of shares of the Company’s common stock outstanding on December 31 of the immediately preceding year; and (ii) 4,300,000 shares, except before the date of any such increase, the Company’s board of directors may determine that such increase will be less than the amount set forth in clauses (i) and (ii). On January 1, 2023, the ESPP authorized shares increased by 1,111,331 shares to 4,111,331 in accordance with the above. As of December 31, 2023, there had been no offering period or purchase period under the ESPP, and no such period will begin unless and until determined by the administrator. Stock Options Prior to the Company’s IPO, the Company granted stock options to its employees, as well as nonemployees (including directors and others who provide subst antial services to the Company) under the Prior Stock Plans, and subsequent to its IPO, under the 2021 Plan . In addition, as part of the Spyce acquisition, see Note 6 for further details, the Company assumed certain options to purchase shares of common stock issued pursuant to the Spyce Food Co. 2016 Stock Option and Grant Plan (the “Spyce Plan”), which, following such assumption, are exercisable for 96,151 shares of the Company’s Class A common stock with a weighted average exercise price of $8.95. The portion of the assumed options under the Spyce plan related to vesting prior to the closing date of the acquisition is included in the fair value of the equity consideration transferred in the acquisition when measuring goodwill. The portion of the assumed options under the Spyce plan that vest after the closing date of the acquisition will be recognized as compensation expense as the assumed options vest. The following table summarizes the Company’s stock option activity for the fiscal years ended December 31, 2023 and December 25, 2022 , including options assumed pursuant to the Spyce Plan, as described above: (dollar amounts in thousands except share and per share amounts) Number of Weighted- Average Exercise Price Per Share Weighted-Average Aggregate Intrinsic Value Balance—December 26, 2021 13,773,414 $ 6.87 7.42 $ 337,269 Options granted 1,482,632 16.63 Options exercised (957,617) 4.97 Options forfeited (437,993) 12.83 Options expired (46,514) 8.20 Balance—December 25, 2022 13,813,922 $ 7.86 6.63 $ 34,454 Options granted 1,588,094 8.66 Options exercised (929,963) 5.79 Options forfeited (1,081,299) 11.25 Options expired (171,366) 11.71 Balance—December 31, 2023 13,219,388 7.77 5.97 $ 53,758 Exercisable—December 31, 2023 10,308,519 6.81 5.26 $ 49,544 Vested and expected to vest—December 31, 2023 13,219,388 7.77 5.97 $ 53,758 The weighted-average fair value of options granted in fiscal years 2023 and 2022 was $9.07 and $8.02, respectively, all of which were granted to employees. The weighted average fair value of options granted in fiscal year 2021 was $7.84 and $4.47 for stock options issued to employees and non-employees, respectively. The fair value of each option granted has been estimated as of the date of the grant using the Black-Scholes option-pricing model with the assumptions during the fiscal years ended December 31, 2023, December 25, 2022 and December 26, 2021 included in the table below. The Company has elected to account for forfeitures as they occur. Input Fiscal Year Ended December 31, 2023 Fiscal Year Ended December 25, 2022 Fiscal Year Ended December 26, 2021 Risk-free interest rate 3.50%-4.90% 1.59%-3.95% 0.46%-1.08% Expected term 5.81-6.22 years 5.08-6.60 years 5.00-6.08 years Expected Volatility 45.11% 44.25 % 41.00 % Dividend yield 0% 0 % 0 % Fair Value of Common Stock — Prior to the Company’s IPO, the absence of an active market for the Company’s common stock requires the Company to estimate the fair value of its common stock. Subsequent to the Company’s IPO, its board of directors determines the fair market value of its common stock based on its closing price as reported on close of business the day immediately preceding the date of grant on the New York Stock Exchange. Risk-Free Interest Rate —The yield on actively traded non-inflation indexed U.S. Treasury notes with the same maturity as the expected term of the underlying options was used as the average risk-free interest rate. Expected Term —The expected term of options granted to was determined based on management’s expectations of the options granted, which are expected to remain outstanding. The Company calculated the expected term using the simplified method for “plain vanilla” stock option awards. Expected Volatility —There is no substantive share price history to calculate volatility and, as such, the Company has elected to use an approximation based on the volatility of other comparable public companies, which compete directly with the Company, over the expected term of the options. Dividend Yield —The Company has not issued regular dividends on common shares in the past nor does the Company expect to issue dividends in the foreseeable future. As such, the dividend yield has been estimated to be zero. As of December 31, 2023 , there was $13.2 million in unrecognized compensation expense related to unvested stock options arrangements and is expected to be recognized over a weighted average period 1.93 years. Restricted Stock Units and Performance Stock Units Restricted stock units During the fiscal year ended December 26, 2021 and prior to the Company’s IPO, excluding the founder PSUs and Spyce PSUs (each as described below), the Company issued 1,980,125 RSUs to certain employees, and 50,000 RSUs to members of its board of directors, both of which vest only upon the satisfaction of both service-based and liquidity event-related performance conditions. The fair value of these RSUs was determined based on contemporaneous third-party valuations of the Company’s common stock, sales of the Company’s redeemable convertible preferred stock to outside investors in arms-length transactions (including the Company’s IPO), the Company’s operating and financial performance, the lack of marketability, and the general and industry-specific economic outlook, amongst other factors. The grant date fair value of RSUs is recognized as compensation expense over the requisite service period, using the accelerated attribution method, once the liquidity event-related performance vesting condition becomes probable of being achieved. The service-based vesting condition is generally satisfied by the award holder providing services to us, typically over a four-year period for employees and a one-year period for members of the Company’s board of directors. The liquidity event-related performance vesting condition was satisfied upon the effectiveness of the Company’s IPO registration statement. Stock-based compensation expense for RSUs that had not met the service-based vesting condition as of December 31, 2023 will be recorded over the remaining requisite service period. During the fiscal years ended December 31, 2023 and December 25, 2022 , the Company issue d 428,428 a nd 724,077 RSUs, respectively, to certain employees, which vest upon the satisfaction of certain service periods. The fair value of these RSUs was determined based on the Company’s closing stock price the business day immediately preceding the date of grant. The service period of these RSUs is satisfied over a range of 0 to 4 years . The RSUs are excluded from common stock issued and outstanding until the satisfaction of these vesting conditions and are not considered a participating security for purposes of calculating net loss per share attributable to common stockholders. The following table summarizes the Company’s RSU activity for fiscal years ended December 31, 2023 and December 25, 2022 : (dollar amounts in thousands except per share amounts) Number of Weighted- Average Grant Date Fair Value Balance—December. 27, 2020 — $ — Granted 2,418,793 24.20 Released (15,000) 23.00 Forfeited, cancelled, or expired (11,367) 29.51 Balance—December. 26, 2021 2,392,426 $ 24.18 Granted 724,077 19.45 Released (838,106) 23.29 Forfeited, cancelled, or expired (497,716) 25.12 Balance—December. 25, 2022 1,780,681 23.40 Granted 428,428 9.07 Released (587,078) 22.08 Forfeited, cancelled, or expired (670,514) 21.19 Balance—December. 31, 2023 951,517 $ 17.41 As of December 31, 2023, unrecognized compensation expense related to RSUs was $8.2 million and is expected to be recognized over a weighted average period of 1.17 years . The fair value of shares earned as of the vesting date during the fiscal years ended December 31, 2023, December 25, 2022 and December 26, 2021 was $6.3 million, $15.3 million and $0.4 million respectively. Performance stock units In October 2021, the Company granted 2,100,000 PSUs to each founder (the “founder PSUs”) for a total of 6,300,000 PSUs, under the 2019 Equity Incentive Plan. The founder PSUs vest upon the satisfaction of a service condition and the achievement of certain stock price goals. The founder PSUs are excluded from common stock issued and outstanding until the satisfaction of these vesting conditions and are not considered a participating security for purposes of calculating net loss per share attributable to common stockholders. The founder PSUs are eligible to vest beginning on the one-year anniversary of the effective date of the registration statement of the Company’s IPO, and expire ten years after the IPO date. The founder PSUs are comprised of seven tranches that are eligible to vest based on the achievement of stock price goals, ranging from $30.0 - $75.0 per share, measured over a consecutive 90-calendar day trailing trading period during the performance period as set forth below. Company Stock Price Target Number of PSUs Eligible to Vest 1 $ 30.00 900,000 2 $ 37.50 900,000 3 $ 45.00 900,000 4 $ 52.50 900,000 5 $ 60.00 900,000 6 $ 67.50 900,000 7 $ 75.00 900,000 The Company estimated the grant date fair value of the founder PSUs based on multiple stock price paths developed through the use of a Monte Carlo simulation model within a hybrid framework with two possible scenarios (IPO and Change of Control). A Monte Carlo simulation model also calculates a derived service period for each of the seven vesting tranches, which is the measure of the expected time to achieve each Company stock price target, as described above. A Monte Carlo simulation model requires the use of various assumptions, including the underlying stock price, volatility, expiration term, and the risk-free interest rate as of the valuation date, corresponding to the length of time remaining in the performance period, and expected dividend yield. The derived service period calculation also requires the cost of equity assumption to be used in the Monte Carlo simulation model. Term and volatility are typically the primary drivers of this valuation. An expiration term of 10 years (as defined in the grant agreements) was considered in the IPO scenario while an expiration term of 3 years was considered in the Change of Control scenario. A volatility of 52.0 percent was considered within the IPO scenario consistent with the maximum term to expiration; whereas, a common stock volatility of 90.5 percent was considered in the Change of Control scenario, which is based on the ASC 718 analysis. The weighted-average grant date fair value of the founders PSUs was $16.35 per share. The Company will recognize total stock-based compensation expense of $103.0 million over the derived service period of each tranche, which is between 1.7 to 4.4 years, using the accelerated attribution method as long as the founders satisfy the service-based vesting condition. As of December 31, 2023 unrecognized compensation expense related to PSUs was $28.5 million and is expected to be recognized over a weighted average period of 1.24 years . Subsequent to the Company’s IPO, the Company issued 321,428 PSUs to the Spyce founders (“Spyce PSUs”) based on three separate performance-based milestone targets. The Company will recognize stock compensation expense related to each performance-based milestone target as it becomes probable of occurring, based on the stock price on the date of grant. During the fiscal years ended December 31, 2023 and December 25, 2022 , the Company h as not recorded any stock-based compensation expense related to the Spyce PSUs. Unrecognized compensation expense related to the Spyce PSUs is $9.8 million, which will be expensed if the performance-based milestone targets become probable of being met. During the fiscal years ended December 31, 2023 and December 25, 2022 the Company did not issue any PSUs. As described above, the Company granted a total of 6,621,248 PSUs during the fiscal year ended December 26, 2021 with a weighted average grant date fair value of $15.56. There were no grants, releases, forfeitures, cancellations, or expirations since the grant date. A summary of stock-based compensation expense recognized fiscal years ended December 31, 2023, December 25, 2022 and December 26, 2021 is as follows: (dollar amounts in thousands) Fiscal Year Ended December 31, 2023 Fiscal Year Ended December 25, 2022 Fiscal Year Ended December 26, 2021 Stock-options $8,878 $10,505 $15,414 Restricted stock units 8,557 32,037 7,219 Performance stock units 32,097 36,194 6,264 Total stock-based compensation $49,532 $78,736 $28,897 Included within the $15.4 million of stock-based compensation expense for stock options during the fiscal year ended December 26, 2021, the Company recorded $5.4 million of stock-based compensation expense for options with a performance-based vesting condition that were satisfied at the closing of the IPO. Stock-based compensation expense is recorded within general and administrative expenses within the Company’s consolidated statements of operations.

Income Tax Disclosure [Abstract]
INCOME TAXES	INCOME TAXES The Company’s entire pretax loss for the fiscal years ended December 31, 2023, December 25, 2022, and December 26, 2021 was from its U.S domestic operations. For the fiscal years ended December 31, 2023, December 25, 2022 and December 26, 2021, the Company recorded an income tax expense of $0.4 million, $1.3 million, and $0.1 million respectively. The components of the provision for income taxes for the fiscal year ended December 31, 2023 and December 25, 2022 are as follows (in thousands): (dollar amounts in thousands) Fiscal Year Ended Fiscal Year Ended December 25, 2022 Current: Federal $ — $ — State 21 55 Total Current 21 55 Deferred: Federal 323 1,271 State 35 19 Total deferred 358 1,290 Total provision for income taxes $ 379 $ 1,345 A reconciliation of the Company’s statutory income tax rate to the Company’s effective income tax rate is as follows: December 31, December 25, December 26, Federal statutory rate 21.0 % 21.0 % 21.0 % Effect of: State taxes, net of federal benefit 6.7 % 7.1 % 6.9 % Permanent differences (0.8 %) (0.8 %) (3.6 %) Change in valuation allowance (18.5 %) (7.8 %) (2.8 %) Nondeductible executive compensation (8.2 %) (19.4 %) (22.9 %) Other (0.5 %) (0.8 %) 1.3 % Total (0.3 %) (0.7 %) (0.1 %) Components of the Company’s net deferred tax (liabilities)/assets consisted of the following: (dollar amounts in thousands) December 31, December 25, Deferred tax assets: Net operating loss carryforward $ 206,452 $ 189,926 Charitable contributions 271 296 Deferred rent 21,045 16,127 Stock-based compensation expense 6,233 4,787 Accrued expenses 580 1,177 Deferred revenue 855 618 Other 5,140 1,061 Total deferred tax assets 240,576 213,992 Valuation allowance (184,880) (163,750) Total deferred tax assets, net of valuation allowance 55,696 50,242 Deferred tax (liabilities): Depreciation and amortization differences (44,691) (40,197) State deferred taxes (12,778) (11,459) Total deferred tax liabilities (57,469) (51,656) Net deferred tax asset (liability) $ (1,773) $ (1,414) As of December 31, 2023 and December 25, 2022, Company management assessed the realizability of deferred tax assets, in order to determine the need for a valuation allowance. As of the fiscal years ended December 31, 2023 and December 25, 2022, the Company is in a net deferred tax asset position of $184.9 million and $163.8 million, respectively. The deferred tax assets consist principally of net operating loss carryforwards. The future realization of the tax benefits from existing temporary differences and tax attributes ultimately depends on the existence of sufficient taxable income. In assessing the realization of the deferred tax assets, management considers whether it is more likely than not that some portion or all of the deferred tax assets will not be realized. Management assesses the available positive and negative evidence to estimate if sufficient future taxable income will be generated to use the existing deferred tax assets. In concluding on its evaluation, Company management placed significant emphasis on guidance in ASC 740, which states that “a cumulative loss in recent years is a significant piece of negative evidence that is difficult to overcome.” Such objective evidence limits the ability to consider other subjective evidence, such as the Company’s projections for future growth. On the basis of this evaluation, as of December 31, 2023 and December 25, 2022, a full valuation allowance of $184.9 million and $163.8 million, respectively, has been recorded against the deferred tax assets, which represents an increase of $21.1 million year over year. As of December 31, 2023, the Company had U.S. Federal net operating loss carryforwards of $754.0 million, of which $652.1 million may be carried forward indefinitely, and the remaining carryforwards $101.9 million expire at various dates from 2029 through 2037. As of December 31, 2023, the Company had state net operating loss carryforwards of $630.2 million, of which $73.0 million may be carried forward indefinitely, and the remaining carryforwards of $557.2 million expire at various dates from 2023 through 2043. The future realization of the Company’s net operating loss carryforwards and other tax attributes may also be limited by the change in ownership rules under the U.S. Internal Revenue Code Section 382. In general, under Section 382 of the Internal Revenue Code (Section 382), a corporation that undergoes an ownership change is subject to limitations on its ability to utilize its pre-change net operating loss carryovers and tax credits to offset future taxable income. The Company completed a Section 382 analysis to evaluate whether any ownership changes and related limitations impacted the Company’s ability to utilize net operating loss carryforwards or other attributes prior to their expiration dates. The Company’s existing net operating loss carryforwards and tax credits are subject to annual limitations arising from ownership changes which occurred in previous periods. Currently, the limitations imposed by Section 382 are not expected to impair the Company’s ability to fully realize its net operating losses. Future changes in the Company’s stock ownership, some of which are outside of the Company’s control, could result in an additional ownership change under Section 382 of the Code; if that occurs, the Company’s ability to utilize net operating losses could be further limited. Furthermore, the Company’s ability to utilize net operating losses of companies that we may acquire in the future may be subject to limitations under Section 382 of the Code. The Company files income tax returns in the U.S. federal jurisdiction and in various state and local jurisdictions in which it operates, and therefore is subject to tax examination by various taxing authorities. The Company is not currently under examination and is not aware of any issues under review that could result in significant payments, accruals or material deviation from its tax positions. As of December 31, 2023 , tax years from 2019 to present remain open to examination under the statutes applied by the relevant taxing jurisdictions in which the Company files tax returns. Additionally, to the extent the Company utilizes tax attribute carryforwards, such as net operating losses, the tax years in which the attribute was generated may still be adjusted upon examination by the Internal Revenue Service and state and local tax authorities. The calculation and assessment of the Company’s tax exposures generally involve the uncertainties in the application of complex tax laws and regulations for federal, state and local jurisdictions. A tax benefit from an uncertain tax position may be recognized when it is more likely than not that the position will be sustained upon examination, including resolutions of any related appeals or litigation, on the basis of the technical merits. As of December 31, 2023 and December 25, 2022, the Company had approximately $0.4 million and $1.6 million of unrecognized tax benefits, respectively. Due to the valuation allowance position, none of the unrecognized tax benefits, if recognized, will impact the Company’s effective tax rate. The Company recognizes accrued interest and penalties, if any, related to uncertain tax positions in income tax provision in its financial statements, if applicable. The Company did not have any accrued interest of penalties associated with any uncertain tax positions, and no interest expense was recognized during the fiscal years ended December 31, 2023 and December 25, 2022. The following table summarizes the activity related to the Company’s gross uncertain tax positions for the fiscal years ended December 31, 2023 and December 25, 2022: (dollar amounts in thousands) December 31, December 25, Uncertain Tax Positions Beginning of year balance $ 1,556 $ 1,333 Increases related to prior year tax positions — — (Decreases) related to prior year tax positions — — (Decreases) increases related to current year tax positions (1,125) 223 (Decreases) related to lapsing of statute of limitations — — End of year balance 431 1,556 On March 27, 2020, President Trump signed into law the CARES Act (as defined below). Intended to provide economic relief to those impacted by the COVID-19 pandemic, the CARES Act includes provisions, among others, to enhance business’ liquidity and provide for refundable employee retention tax credits, which could be used to offset payroll tax liabilities. On March 11, 2021, President Biden signed the American Rescue Plan Act (“ARPA”). The ARPA includes several provisions, such as measures that extend and expand the employee retention credit, previously enacted under the Coronavirus Aid, Relief and Economic Security Act (“CARES Act”), through December 31, 2021. The ARPA did not have a material impact on the Company’s consolidated financial statements. 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 Employee Retention Credit “ERC” by analogy to International Accounting Standard ("IAS”) 20, Accounting for Government Grants and Disclosure of Government Assistance. In accordance with IAS 20, management determined it has reasonable assurance for receipt of the ERC and recorded the ERC benefit of $1.8 million within Labor and other related expenses and $5.1 million, within general and administrative expenses in the Consolidated Statement of Operations for the fiscal year ended December 31, 2023 as an offset to Social Security tax expense. As of December 31, 2023 the Company received $3.4 million cash payment reducing the ERC receivable within other current assets On August 16, 2022, President Biden signed the Inflation Reduction Act of 2022 (the “IRA”) into law. The IRA contains several revisions to the Internal Revenue Code, including 15% corporate minimum income tax for entities with adjusted financial statement income of over $1.0 billion and a 1% excise tax on corporate stock repurchases in tax years beginning after December 31, 2022. These tax law changes did not have a material effect on the Company’s results of operations.

Earnings Per Share [Abstract]
NET LOSS PER SHARE	NET LOSS PER SHARE During the fiscal years ended December 31, 2023, December 25, 2022, and December 26, 2021, the rights, including the liquidation and dividend rights, of the holders of Class A and Class B common stock were identical, except with respect to voting. As the liquidation and dividend rights were identical, the undistributed earnings were allocated on a proportionate basis and the resulting net loss per share attributable to common stockholders were, therefore, the same for both Class A and Class B common stock on an individual or combined basis. On November 22, 2021, the Company completed its IPO, in which it issued and sold 14,950,000 shares of its Class A common stock at a price of $28.00 per share. On that date, all of the Company’s outstanding preferred stock automatically converted into 69,231,197 shares of Class A common stock. These shares were included in the Company’s issued and outstanding common stock starting on that date. Additionally, 1,843,493 shares of outstanding Class S stock issued in connection with the Company’s acquisition of Spyce in September 2021 were converted into 1,316,763 shares of Class A common stock, the Series J Warrants were automatically exercised upon the IPO for 1,557,686 shares of Class A common stock and the Series F Warrants were exercised during fiscal year 2021 and converted into 235,000 shares of Class A common stock in connection with the IPO. See Note 1. The following table sets forth the computation of net loss per common share: (dollar amounts in thousands) Fiscal Year Ended December 31, 2023 Fiscal Year Ended December 25, 2022 Fiscal Year Ended December 26, 2021 Numerator: Net loss $ (113,384) $ (190,441) $ (153,175) Denominator: Weighted-average common shares outstanding—basic and diluted 111,907,675 110,128,287 27,782,442 Earnings per share—basic and diluted $ (1.01) $ (1.73) $ (5.51) The Company’s potentially dilutive securities, which include preferred stock and options to purchase common stock, have been excluded from the computation of diluted net loss per share as the effect would be antidilutive. Therefore, the weighted-average number of common shares outstanding used to calculate both basic and diluted net loss per share is the same. The Company excluded the following potential common shares, presented based on amounts outstanding at each period end, from the computation of diluted net loss per share for the periods indicated because including them would have had an anti-dilutive effect: Fiscal Year Ended December 31, 2023 Fiscal Year Ended December 25, 2022 Fiscal Year Ended December 26, 2021 Options to purchase common stock 13,219,388 13,813,922 13,773,414 Time-based vesting restricted stock units 951,517 1,780,681 2,392,426 Performance stock units 6,621,428 6,621,428 6,621,428 Contingently issuable stock 714,285 714,285 714,285 Total common stock equivalents 21,506,618 22,930,316 23,501,553

Commitments and Contingencies Disclosure [Abstract]
COMMITMENTS AND CONTINGENCIES	COMMITMENTS AND CONTINGENCIES Lease Commitments The Company is obligated under various operating leases related to its office facilities, restaurant locations, and certain equipment under non-cancelable operating leases that expire on various dates. Under certain of these leases, the Company is liable for contingent rent based on a percentage of sales in excess of specified thresholds and typically responsible for its proportionate share of real estate taxes, CAMs and other occupancy costs. Refer to Note 9, Leases, for additional information. Purchase Obligations Purchase obligations include agreements to purchase goods or services that are enforceable and legally binding on us and that specify all significant terms. The majority of the Company’s purchase obligations relate to amounts owed for supplies within its restaurants. Litigation The Company is subject to various claims, lawsuits, governmental investigations and administrative proceedings that arise in the ordinary course of business. The Company does not believe that the ultimate resolution of any of these matters will have a material effect on the Company’s financial position, results of operations, liquidity, or capital resources. However, an increase in the number of these claims, or one or more successful claims under which the Company incurs greater liabilities than the Company currently anticipates, could materially and adversely affect the Company’s business, financial position, results of operations, and cash flows.

Accounting Policies [Abstract]
Principles of Consolidation	Principles of Consolidation —The accompanying consolidated financial statements include the accounts of the Company. All intercompany balances and transactions have been eliminated in consolidation.
Fiscal Year	Fiscal Year —The Company’s fiscal year is a 52- or 53-week period that ends on the last Sunday of the calendar year. Fiscal year 2023 was a 53-week period that ended December 31, 2023. Fiscal years 2022 and 2021 were 52-week periods that ended December 25, 2022 and December 26, 2021, respectively. In a 53-week fiscal year, the first, second and third quarters each include 13 weeks of operations, and the fourth quarter includes 14 weeks of operations. In a 52-week fiscal year, each quarter includes 13 weeks of operations.
Management’s Use of Estimates	Management’s Use of Estimates —The consolidated financial statements have been prepared by the Company in accordance with accounting principles generally accepted in the United States of America (“GAAP”) and the rules and regulations of the Securities and Exchange Commission (“SEC”). The preparation of consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect certain reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the consolidated financial statements and the reported amounts of revenues and expenses during the reporting period. Significant accounting estimates made by the Company include the income tax valuation allowance, impairment of long-lived assets and right-of-use assets (“ROU assets”), legal liabilities, valuation of the contingent consideration liability, lease accounting matters, valuation of intangible assets acquired in business combinations, goodwill, and stock-based compensation. These estimates are based on information available as of the date of the consolidated financial statements; therefore, actual results could differ from those estimates.
Cash and Cash Equivalents	Cash and Cash Equivalents
Restricted Cash	Restricted Cash
Concentrations of Risk	Concentrations of Risk
Other Current Assets	Other Current Assets — Other current assets primarily consist of the Employee Retention Credit “ERC”, outstanding receivables from the Company’s distributors and current amortization of deferred costs.
Other Assets	Other Assets
Accounts Receivable	Accounts Receivable — Accounts receivable primarily consists of receivables from distributors and receivables from the Company’s Marketplace and Outpost and Catering Channels.
Inventory	Inventory — Inventory, consisting primarily of food, beverages and supplies, is valued at the lower of cost first-in, first-out cost or net realizable value.
Prepaid Expenses	Prepaid Expenses — Prepaid expenses primarily include prepaid insurance, which is expensed in the period for which it relates.
Property and Equipment	Property and Equipment —Property and equipment are recorded at cost. Property and equipment are depreciated using the straight-line method over the following estimated useful lives: Property and Equipment Useful Life Leasehold improvements Shorter of lease term or estimated asset life Furniture and fixtures 5 years Kitchen equipment 5 years Computers and other equipment 3 years Upon retirement or disposal of assets, the accounts are relieved of cost and accumulated depreciation and any related gain or loss is reflected in loss on disposal of property and equipment in the consolidated statement of operations. Assets to be disposed consists of primarily furniture, equipment and fixtures that were replaced in the normal course of business and are reported at the lower of their carrying amount or fair value less estimated cost to sell. Expenditures for repairs and maintenance are charged directly to expense when incurred. The cost of assets sold, retired, or otherwise disposed of, and the related accumulated depreciation and amortization are eliminated from the accounts, and any resulting gain or loss is included in earnings.
Restructuring Charges	Restructuring Charges — Restructuring charges are expenses that are paid in connection with reorganization of the Company’s operations during fiscal year 2022.
Business Combinations	Business Combinations —The Company utilizes the acquisition method of accounting in any acquisitions or business combinations. The acquisition method of accounting requires companies to assign values to assets and liabilities acquired based upon their fair values at the acquisition date. In most instances, there are not readily defined or listed market prices for individual assets and liabilities acquired in connection with a business, including intangible assets. The determination of fair value for assets and liabilities in many instances requires a high degree of estimation. The valuation of intangible assets, in particular, is very subjective. The Company generally obtains third-party valuations to assist it in estimating fair values. The use of different valuation techniques and assumptions could change the amounts and useful lives assigned to the assets and liabilities acquired and related amortization expense. Total research and development excluding any related cost associated with the Spyce acquisition was $1.2 million and $2.0 million for the fiscal years ended December 31, 2023 and December 25, 2022, respectively. These costs are recorded within general and administrative cost in the Company’s accompanying consolidated statement of operations. Contingent Consideration —Due to certain conversion features, the contingent consideration issued as part of the Spyce acquisition (see Note 6 for further details) is considered a liability in accordance with ASC 480. The liability associated with the contingent consideration is initially recorded at fair value (see Note 3 for further details) upon issuance date and is subsequently re-measured to fair value at each reporting date. The initial fair value of the liability for the contingent consideration was $16.4 million and was included as part of the purchase price for the Spyce acquisition. The fair value of the liability as of December 31, 2023 and December 25, 2022 was $8.4 million and $21.3 million, respectively. During fiscal year ended December 31, 2023, the Company paid $10.4 million of the contingent consideration. See Note 3. Changes in fair value of the contingent consideration is recognized within other expense in the accompanying consolidated statement of operations.
Other Current Liabilities	Other Current Liabilities
Goodwill	Goodwill —Goodwill, which represents the excess of the cost of an acquired entity over the fair value of the acquired net assets, has an indefinite life and, accordingly, is not amortized. The Company has one reporting unit. The Company tests goodwill for impairment annually, or more frequently if events or changes in circumstances indicate that the asset may be impaired. The Company reviews goodwill for impairment utilizing either a qualitative assessment or a fair value test by comparing the fair value of its reporting unit with its carrying amount. If the Company decides that it is appropriate to perform a qualitative assessment and concludes that the fair value of its reporting unit more likely than not exceeds its carrying value, no further evaluation is necessary. If the Company performs the fair value test, the Company will compare the fair value of a reporting unit with its carrying amount, including goodwill. If the fair value of a reporting unit exceeds its carrying amount, goodwill of the reporting unit is considered not impaired. If the carrying amount of a reporting unit exceeds its fair value, the Company will recognize an impairment charge for the amount by which the carrying amount exceeds its reporting unit’s fair value.
Intangible Assets, net	Intangible Assets, net — External costs and certain internal costs, including payroll and payroll-related costs for employees, directly associated with developing computer software applications for internal use are capitalized subsequent to the preliminary stage of development. Internal-use software costs are amortized using the straight-line method over a three-year estimated useful life of the software when the project is substantially complete and ready for its intended use.
Leases and Lease Acquisition Costs	Lease Acquisition Costs —Prior to the adoption of ASC 842, lease acquisition costs included key money and legal and broker fees incurred to obtain a lease. Key money is the amount of funds paid to a landlord or tenant to acquire the rights of tenancy under a commercial property lease. These costs were amortized over the respective lease terms that range from 10 to 15 years and are presented net of accumulated amortization. Amortization expense for the fiscal year ended December 26, 2021 was $0.4 million, of which all but an insignificant amount was included in occupancy and related expenses and the remainder was included in general and administrative expenses in the accompanying consolidated statement of operations. Upon adoption of ASC 842, lease acquisition costs associated with legal and broker fees are expensed as incurred and no longer capitalized. As such, lease acquisition costs only include key money. Total lease acquisition costs, net of accumulated amortization, as of December 31, 2023 and December 25, 2022 were $0.5 million and $0.6 million, respectively. Amortization expense for both the fiscal years ended December 31, 2023 and December 25, 2022 was $0.1 million, which was recorded within occupancy and related expenses in the accompanying statement of operations. Further, the Company recorded $1.7 million of legal fee expenses associated with obtaining a lease for the fiscal year ended December 25, 2022 which was recorded to general and administrative expenses within the consolidated statement of operations. The Company also recorded a $4.2 million adjustment to accumulated deficit as of the effective date of the adoption of ASC 842, related to legal fees no longer capitalizable. See Note 9. Leases — The Company leases restaurants and corporate office space under various non-cancelable lease agreements that expire on various dates through 2033. Lease terms for restaurants generally include a base term of 10 years, with options to extend these leases for additional periods of 5 to 15 years. 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 it obtains substantially all economic benefits from the use of the asset, and whether it has the right to direct the use of the asset. If these criteria are met and the contract is identified as a lease, then the Company accounts for the contract under the requirements of ASC 842. The Company also evaluates whether the lease will be accounted for as an operating or finance lease based on the terms of the lease agreement, and when determining the lease term, the Company includes reasonably certain option renewal periods. Many of the Company's leases require payment of real estate taxes, CAM costs and other occupancy costs which are included in occupancy and related expenses on the consolidated statements of operations. Some of the Company’s operating leases include provisions for payment of a fixed CAM amount per annum, and as such, these payments have been included in the calculation of the operating lease liability. As of the date of adoption, the Company calculated its 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 measured the lease liability by discounting the future fixed contractual payments included in the lease agreement, using either the rate explicit in the lease or its incremental borrowing rate (“IBR”). The IBR used to measure the lease liability is derived from the yield curve commensurate with the credit rating of the Company and further adjusted for seniority based on a notching analysis. The most significant assumption in calculating the IBR is the Company’s credit rating, and the IBR is also subject to judgment. 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 applied ASC 842 using the effective date method, which allowed the Company to apply the standard as of the adoption date, and to recognize the cumulative effect of initially applying ASC 842 as an adjustment to accumulated deficit at December 27, 2021. See Note 9. Therefore, the comparative information for the fiscal year ended December 26, 2021 has not been adjusted and continues to be reported under ASC 840. Certain leases contain provisions for contingent rent that require additional rental payments based upon restaurant sales volume. Contingent rent is expensed each period as the liability is incurred, and is not included in the initial measurement of operating lease assets and liabilities. The Company receives tenant improvement allowances, generally in the form of cash, from some of the landlords of its leased properties. The tenant improvement allowances that are expected to be received are included 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 and amortized over the applicable lease terms. For periods prior to the adoption of ASC 842, leases are accounted for under ASC 840. Under ASC 840, minimum lease payments, including minimum scheduled rent increases, are recognized as rent expense on a straight-line basis over the applicable lease terms. The term used for rent expense is calculated initially from the date of lease commencement through the lease term. Certain lease agreements contain a free rent holiday period that generally begins on the lease commencement date and ends on the rent commencement date. During the free rent holiday period, no cash rent payments are due under the terms of the lease. In addition, certain leases contain fixed escalations throughout the lease term. Expense is recorded for both free rent holiday periods and fixed escalations on a straight-line basis over the lease term. The difference between the cash paid to the property owner and the amount recognized as rent expense on the straight-line basis is included as deferred rent liability in the accompanying consolidated balance sheet. Tenant improvement allowances received and earned are recorded as deferred rent liability in the accompanying consolidated balance sheet and amortized on a straight-line basis as a reduction to rent expense over the applicable lease terms.
Revenue Recognition	Revenue Recognition —The Company recognizes food and beverage revenue, net of discounts and incentives, when payment is tendered at the point of sale as the performance obligation has been satisfied, through the Company’s three disaggregated revenue channels: Owned Digital Channels, In Store-Channel (Non-Digital component), and Marketplace Channel. Owned Digital Channels encompasses the Company’s Pick-Up Channel, Native Delivery Channel, Outpost and Catering Channel, and purchases made in its In-Store Channel via digital scan-to-pay, prior to the elimination of digital scan-to-pay during the fiscal quarter ended September 24, 2023. Pick-Up Channel refers to sales to customers made for pick-up at one of the Company’s restaurants through the Sweetgreen website or mobile app. Native Delivery Channel refers to sales to customers for delivery made through the Sweetgreen website or mobile app. Outpost and Catering Channel refers to sales to customers for delivery made through the Sweetgreen website or mobile app to Outposts, which are the Company’s offsite drop-off points at offices, residential buildings and hospitals. In addition, the Company’s Outpost and Catering Channel includes the Company’s catering offerings, which refer to sales to customers made through the Company’s catering website for pickup at one of the Company’s restaurants or delivery to a customer-specified address. In-Store Channel (Non-Digital component) refers to sales to customers who make in-store purchases in the Company’s restaurants, whether they pay by cash or credit card, or digital scan-to-pay. Digital scan-to-pay was eliminated during the fiscal quarter ended September 24, 2023. Purchases made in the Company’s In-Store Channel via cash or credit card are referred to as “Non-Digital” transactions, and purchases made in the Company’s In-Store Channel via digital scan-to-pay, prior to its elimination, were included as part of the Company’s Owned Digital Channels. Marketplace Channel refers to sales to customers for delivery or pick-up made through third-party delivery marketplaces, including DoorDash, Grubhub, Uber Eats, ezCater, Sharebite and others. Provisions for discounts are provided for in the same period the related sales are recorded. Sales taxes and other taxes collected from customers and remitted to governmental authorities are presented on a net basis, and as such, are excluded from revenues. Gift Cards —The Company sells gift cards that do not have an expiration date. Upon sale, gift cards are recorded as unearned revenue and included within gift card liability in the accompanying consolidated balance sheets. The revenue from gift cards is recognized when redeemed by customers. Because the Company does not track addresses of gift card purchasers, the relevant jurisdiction related to the requirement for escheatment, the legal obligation to remit unclaimed assets to the state, is the Company’s state of incorporation, which is Delaware. The state of Delaware requires escheatment after 5 years from issuance. The Company does not recognize breakage income because of its requirements to escheat unredeemed gift card balances. Delivery —The majority of the Company’s restaurant locations offer a delivery option. Delivery services are fulfilled by third-party service providers whether delivery is ordered through the Company’s Native Delivery Channel or Marketplace Channel. With respect to Native Delivery sales, the Company controls the delivery services and recognizes revenue, including delivery revenue, when the delivery partner transfers food or beverage to the customer. For these sales, the Company receives payment directly from the customer at the time of sale. With respect to Marketplace Channel sales, the Company recognizes revenue, excluding delivery fees collected by the delivery partner as the Company does not control the delivery service, when control of the food is delivered to the end customer. The Company receives payment from the delivery partner subsequent to the transfer of food and the payment terms are short-term in nature. For all delivery sales, the Company is considered the principal and recognize the revenue on a gross basis.
Income Taxes	Income Taxes —The Company is subject to federal and state income taxes. The Company uses the asset and liability method of accounting for income taxes as set forth in ASC 740, Income Taxes . Under this method, the Company recognizes deferred tax assets and liabilities for the expected future tax consequences of temporary differences between the respective carrying amounts and tax basis of assets and liabilities. All deferred tax assets and liabilities are classified as non-current in the accompanying consolidated balance sheet. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in income in the period that includes the enactment date. A valuation allowance is established against the portion of deferred tax assets that the Company believes will not be realized on a more-likely-than-not basis.
Fair Value of Financial Instruments	Fair Value of Financial Instruments —The fair value measurement accounting guidance creates a fair value hierarchy to prioritize the inputs used to measure fair value into three categories. A financial instrument’s level within the fair value hierarchy is based on the lowest level of input significant to the fair value measurement, where Level 1 is the highest category (observable inputs) and Level 3 is the lowest category (unobservable inputs). The three levels are defined as follows: Level 1 —Quoted prices for identical instruments in active markets. Level 2 —Quoted prices for similar instruments in active markets, quoted prices for identical or similar instruments in markets that are not active and model-derived valuations in which significant value drivers are observable. Level 3 —Unobservable inputs for the asset or liability. This includes certain pricing models, discounted cash flow methodologies and similar techniques that use significant unobservable inputs. The carrying amount of accounts receivable, other current assets, accounts payable, accrued payroll and accrued expenses approximates fair value due to the short-term maturity of these financial instruments. The Company’s contingent consideration liability is carried at fair value determined using Level 3 inputs in the fair value. See Note 3. Certain assets and liabilities are measured at fair value on a nonrecurring basis. In other words, the instruments are not measured at fair value on an ongoing basis but are subject to fair value adjustments only in certain circumstances (for example, when there is evidence of impairment). See Note 3.
Impairment and Closure Costs	Impairment and Closure Costs — Impairment includes impairment charges related to our long-lived assets, which include property and equipment and internally developed software, and subsequent to the adoption of ASC 842, operating lease assets. Long-lived assets are reviewed for recoverability at the lowest level in which there are identifiable cash flows (“asset group”). The asset group is at the store-level for restaurant assets and the corporate-level for corporate assets. The carrying amount of a store asset group includes stores’ property and equipment, primarily leasehold improvements, and operating lease assets, net of operating lease liability. The carrying amount of a corporate-level asset group includes support center property and equipment, operating lease assets, internally developed software and internally developed technology. Long-lived assets are reviewed by management for impairment whenever events or changes in circumstances indicate that the carrying amount of the asset may not be fully recoverable. When events or circumstances indicate that impairment may be present, management evaluates the probability that future undiscounted net cash flows received will be less than the carrying amount of the asset group. If projected future undiscounted cash flows are less than the carrying value of an asset group, then such assets are written down to their fair values. The Company uses a discounted cash flow model to measure the fair value of an asset group. An impairment charge will be recognized in the amount by which the carrying amount of the store asset group exceeds its fair value. The resulting impairment charge, if any, is allocated to the property and equipment, primarily leasehold improvements, and operating lease assets on a pro rata basis using the relative carrying amounts of those assets. The allocated impairment charge to a long-lived asset is limited to the extent that the impairment charge does not reduce the carrying amount of the long-lived asset below its individual fair value. The estimation of the fair value of an operating lease asset primarily involves the evaluation of current and future market value rental amounts, which are primarily based on recent observable market rental data. The fair value of an operating lease asset is measured using a discounted cash flow valuation technique by discounting the estimated current and future market rental values using a property-specific discount rate. A number of significant assumptions and estimates are involved in the application of the model to forecast operating cash flows, which are largely unobservable inputs, including future revenue projections. Accordingly, such significant assumptions are classified as Level 3 inputs within the fair value hierarchy. Assumptions used in these forecasts are consistent with internal planning, and include sales growth rates, gross margins, and operating expense in relation to the current economic environment and the Company’s future expectations, competitive factors in its various markets, inflation, sales trends and other relevant economic factors that may impact the store under evaluation. In addition, assumptions used for operating lease assets vacated for future sublease include the Company’s estimated future sublease income and a property specific discount rate. There is uncertainty in the projected undiscounted future cash flows used in the Company’s impairment review analysis, which requires the use of estimates and assumptions. If actual performance does not achieve the projections, or if the assumptions used change in the future, the Company may be required to recognize impairment charges in future periods, and such charges could be material. The Company determined that triggering events, primarily related to the impact of changing customer behavior trends, including slower than expected return to office during and following the COVID-19 pandemic (including as a result of many workplaces adopting remote or hybrid models) and as a result of broader macroeconomic conditions on the Company’s near-term restaurant level cash flow forecast, restructuring activities and anticipated store closures, occurred for certain restaurants and its Support Center, that required an impairment review of the Company’s long-lived assets. No indicators of impairment were found for the Company’s intangible assets for the fiscal years ended December 31, 2023, December 25, 2022, and December 26, 2021. Based on the results of this analysis, the Company recorded non-cash impairment charges of $4.3 million during the fiscal year ended December 31, 2023, related to the operating lease asset for the Company’s former Sweetgreen Support Center vacated previously during fiscal year 2022, which was recorded under restructuring charges restructuring charges restructuring charges impairment and closure costs restructuring charges impairment and closure costs operations. During the fiscal year ended December 26, 2021, the Company recorded non-cash impairment charges of $4.4 million, related to certain of the Company’s stores, as well as the two stores operated by Spyce Food Co. (“Spyce”). Prior to the adoption of ASC 842, closure costs included non-cash restaurant charges such as up-front expensing the net present value of unpaid rent remaining on the life of a lease offset by assumed sublease income. Subsequent to the adoption of ASC 842, closure costs include lease and related costs associated with closed restaurants including the amortization of the operating lease asset, and expenses associated with common area maintenance fees and real estate taxes for previously impaired stores.
Contingencies	Contingencies —The Company is subject to various claims, lawsuits, governmental investigations, and administrative proceedings that arise in the ordinary course of business. The Company accrues a liability (which includes litigation costs expected to be incurred) and recognizes an expense for such matters when it is probable that a liability has been incurred and the amount can be reasonably estimated. Estimating liabilities and costs associated with these matters require significant judgment based upon the professional knowledge and experience of management and its legal counsel.
Marketing And Public Relations	Marketing and Public Relations
Restaurant operating costs	Restaurant Operating Costs— Restaurant operating costs primarily consist of food, beverage, packaging costs for to-go orders, salaries, benefits, and other expenses related to the Company’s in-store employees, maintenance and utilities at the Company’s restaurants, leasing costs for the Company’s restaurants and delivery and processing fees.
Operating Expenses	Operating Expenses— Operating expenses primarily consist of operations, finance, legal, human resources, administrative personnel, stock-based compensation, depreciation and amortization of assets, and pre-opening costs. Pre-opening costs primarily consist of rent, wages, travel for training and store opening teams, food and other restaurant costs that the Company incurs prior to the opening of a restaurant. These costs are expensed as incurred.
Share-Based Compensation	Stock-Based Compensation —The Company recognizes compensation expense resulting from stock-based payments over the period for which the requisite services are provided. The Company uses the Black-Scholes-Merton (“Black-Scholes”) option-pricing model to estimate the fair value of the incentive stock options at the measurement date. Grant date is deemed to be the appropriate measurement date for stock options issued to employees and nonemployees. The use of the Black-Scholes option-pricing model requires the use of subjective assumptions, including the fair value and projected volatility of the underlying common stock and the expected term of the award. For all stock options granted, the Company calculated the expected term using the simplified method for “plain vanilla” stock option awards. The risk-free interest rate is based on the yield available on U.S. Treasury zero-coupon issues similar in duration to the expected term of the stock-based award. The Company’s common stock has not been publicly traded over the full expected term, and therefore, the Company used the historical volatility of the stock price of similar publicly traded peer companies. The Company utilized a dividend yield of zero, as it had no history or plan of declaring dividends on its common stock. The grant date fair value of restricted stock units (“RSUs”) is estimated based on the fair value of the Company’s common stock on the date of grant. Prior to the Company’s IPO in November 2021, RSUs granted by the Company vest upon the satisfaction of both a service-based vesting condition, which is typically four years, and a liquidity event-related performance vesting condition. The liquidity event-related performance vesting condition was achieved upon the consummation of the Company's IPO. Stock-based compensation related to the remaining service-based period after the liquidity event-related performance vesting condition was satisfied will be recorded over the remaining requisite service period using the accelerated attribution method. Since the Company’s IPO in November 2021, the Company only granted RSUs that vest upon the satisfaction of a service-based vesting condition and the compensation expense for these RSUs is recognized on a straight-line basis over the requisite service period. The Company has granted founder performance-based restricted stock units (“founder PSUs”) that contain a market condition in the form of future stock price targets. The grant date fair value of the founder PSUs was determined using a Monte Carlo simulation model and the Company estimates the derived service period of the founder PSUs. The grant date fair value of founder PSUs containing a market condition is recorded as stock-based compensation over the derived service period using the accelerated attribution method. If the stock price goals are met sooner than the derived service period, any unrecognized compensation expenses related to the founder PSUs will be expensed during the period the stock price targets are achieved. Provided that each founder continues to be employed by the Company through the derived service period, stock-based compensation expense is recognized over the derived service period, regardless of whether the stock price goals are achieved. Prior to the Company’s IPO, the Company determined that the Option Pricing Method (“OPM”) was the most appropriate method for determining the fair value of its common stock. Under the OPM, shares are valued by creating a series of call options with exercise prices based on the liquidation preferences and conversion terms of each equity class. The estimated fair values of the common stock are inferred by analyzing these options.
Interest Income	Interest Income —Interest income consists of interest earned on cash and cash equivalents.
Interest Expense	Interest Expense —Interest expense includes mainly the interest incurred on outstanding indebtedness, as well as amortization of deferred financing costs, mainly debt origination and commitment fees. Debt origination fees are amortized on a straight-line basis over the commitment period.
Net Loss Per Share	Net Loss Per Share —The Company calculated basic and diluted net loss per share attributable to common stockholders using the two-class method required for companies with participating securities. The Company considers its previously outstanding preferred stock to be participating securities as the holders are entitled to receive non-cumulative dividends on a pari passu basis in the event that a dividend is paid on common stock. Under the two-class method, basic net loss per share available to common shareholders was calculated by dividing the net loss available to common shareholders by the weighted-average number of shares of common stock outstanding during the period. Prior to the IPO, the net loss available to common shareholders was not allocated to the preferred stock as the holders of preferred stock did not have a contractual obligation to share in losses.

Recently Adopted Accounting Pronouncements and Recently Issued Accounting Pronouncements Not Yet Adopted	Recently Adopted Accounting Pronouncements In February 2016, the FASB issued ASU No. 2016-02, “Leases”. ASC 842 establishes a right-of-use model that requires a lessee to record an ROU Asset and a lease liability on the balance sheet for all leases with terms longer than 12 months. Leases will be classified as either finance or operating, with classification affecting the pattern of expense recognition in the income statement. The new standard was effective for fiscal years beginning after December 15, 2018, including interim periods therein. In July 2018, the FASB issued ASU No. 2018-11, which provides an alternative transition method that allows entities to apply the new leases standard at the adoption date and recognize a cumulative-effect adjustment to the opening balance of retained earnings in the period of adoption. In June 2020, the FASB issued ASU No. 2020-05 which delayed the effective date to fiscal years beginning after December 15, 2021, and interim periods within fiscal years beginning after December 15, 2022. The Company adopted ASC 842, and all related topics as of December 27, 2021. See Note 9. The Company did not elect the package of three practical expedients, and thus reassessed all contracts for lease identification, lease classification and initial direct costs. There was no change related to lease identification or lease classification and the reassessment of initial direct costs resulted in a cumulative-effect adjustment in retained earnings, related to previously capitalized legal fees that will no longer meet the definition of initial direct costs under the new standard. Additionally, the Company recognized a cumulative-effect adjustment in retained earnings, related to impairment of operating lease assets existing as of the implementation date. The Company also did not elect the hindsight practical expedient, which permits the use of hindsight when determining lease term and impairment of right-of-use assets. Further, the Company elected a short-term lease exception policy, permitting it to not apply the recognition requirements of this standard to short-term leases (i.e. leases with terms of 12 months or less) and an accounting policy to account for lease and non-lease components as a single component for all leases. See Note 9. Recently Issued Accounting Pronouncements Not Yet Adopted In December 2023, the FASB issued ASU No. 2023-09, “Income Taxes (Topic 740): Improvements to Income Tax Disclosures.” The ASU includes amendments requiring enhanced income tax disclosures, primarily related to standardization and disaggregation of rate reconciliation categories and income taxes paid by jurisdiction. The guidance is effective for fiscal years beginning after December 15, 2024, with early adoption permitted, and should be applied either prospectively or retrospectively. The Company is currently evaluating the impact of adopting this ASU on our disclosures.
