Organization, Consolidation and Presentation of Financial Statements [Abstract]
Organization and Operations	Organization and Operations SVF Investment Corp. 3, formerly known as SVF Investment III Corp., (“SVF 3” and, after the Domestication as described below, “Symbotic” or the “Company”) was a blank check company incorporated as a Cayman Islands exempted company on December 11, 2020. SVF 3 was incorporated for the purpose of effecting a merger, share exchange, asset acquisition, share purchase, reorganization, or similar business combination with one or more businesses. Warehouse Technologies LLC (“Legacy Warehouse”), a New Hampshire limited liability company, was formed in December 2006 to make investments in companies that develop new technologies to improve operating efficiencies in modern warehouses. Symbotic LLC, a technology company that develops and commercializes innovative technologies for use within warehouse operations and Symbotic Group Holdings, ULC (“Symbotic Canada”) were wholly-owned subsidiaries of Legacy Warehouse. On December 12, 2021, (i) SVF 3 entered into an Agreement and Plan of Merger (the “Merger Agreement”) with Legacy Warehouse, Symbotic Holdings LLC, a Delaware limited liability company (“Symbotic Holdings”), and Saturn Acquisition (DE) Corp., a Delaware corporation and wholly owned subsidiary of SVF 3 (“Merger Sub”) and (ii) Legacy Warehouse entered into an Agreement and Plan of Merger (the “Company Merger Agreement”) with Symbotic Holdings. On June 7, 2022, as contemplated by the Company Merger Agreement, Legacy Warehouse merged with and into Symbotic Holdings (the “Company Reorganization”), with Symbotic Holdings surviving the merger (“Interim Symbotic”). Immediately following such merger, on June 7, 2022, as contemplated by the Merger Agreement, SVF 3 filed a notice of deregistration with the Cayman Islands Registrar of Companies, together with the necessary accompanying documents, and filed a certificate of incorporation and a certificate of corporate domestication with the Secretary of State of the State of Delaware, under which SVF 3 was transferred by way of continuation from the Cayman Islands and domesticated as a Delaware corporation, changing its name to “Symbotic Inc.” (the “Domestication”). Immediately following the Domestication of SVF 3, on June 7, 2022, as contemplated by the Merger Agreement, Merger Sub merged with and into Interim Symbotic (the “Merger” and, together with the Company Reorganization, the “Business Combination”), with Interim Symbotic surviving the merger as a subsidiary of Symbotic (“New Symbotic Holdings”). The Business Combination is further described in Note 4, Mergers and Acquisitions . Symbotic is an automation technology company established to develop technologies to improve operating efficiencies in modern warehouses. The Company's vision is to make the supply chain work better for everyone. The Company does this by developing innovative, comprehensive technology solutions that dramatically improve supply chain operations. The Company currently automates the processing of pallets and cases in large warehouses or distribution centers for some of the largest retail companies in the world. Its systems enhance operations at the front end of the supply chain, and therefore benefit all supply partners further down the chain, irrespective of fulfillment strategy. The Company's headquarters are located in Wilmington, Massachusetts, and its Canadian headquarters are located in Montreal, Quebec.

Accounting Policies [Abstract]
Summary of Significant Accounting Policies	Summary of Significant Accounting Policies Basis of Presentation and Foreign Currency Translation The consolidated financial statements have been prepared in U.S. dollars, in accordance with accounting principles generally accepted in the United States of America (“GAAP”). The accompanying consolidated financial statements include the accounts of the Company and its wholly-owned subsidiaries and majority-owned subsidiaries. The consolidated financial statements include 100% of the accounts of wholly-owned and majority-owned subsidiaries and the ownership interest of the minority investors are recorded as a non-controlling interest in a subsidiary. All intercompany balances and transactions have been eliminated in consolidation. The functional currency for the Company’s foreign subsidiaries is based on the subsidiaries’ financial and operational environment and is the applicable local currency. For the Company’s subsidiaries that transact in a functional currency other than the U.S. dollar, assets and liabilities are translated into U.S. dollars at period-end foreign exchange rates. Revenue and expenses are translated into U.S. dollars at the average foreign exchange rates for the period. Translation adjustments are excluded from the determination of net income and are recorded in accumulated other comprehensive income (loss), a separate component of members’ deficit. Certain transactions of the Company and its subsidiaries are denominated in currencies other than the functional currency. Foreign currency transaction losses were less than $0.1 million for the year ended September 28, 2024, and less than $0.1 million for the years ended September 30, 2023 and September 24, 2022, and were recorded within other income, net on the consolidated statements of operations. The Company operates and reports using a 52-53 week fiscal year ending on the last Saturday closest to September 30. Accordingly, the Company’s fiscal quarters end on the last Saturday that falls closest to the last day of the third month of each quarter. The fiscal year ended September 28, 2024 was a 52-week period, the fiscal year ended September 30, 2023 was a 53-week period, and the fiscal year ended September 24, 2022 was a 52-week period. Restatement of Previously Issued Unaudited Condensed Consolidated Financial Statements As described in Note 3, Restatement of Previously Issued Unaudited Condensed Consolidated Financial Statements , the Company’s unaudited condensed consolidated financial statements as of and for the fiscal quarters ended December 30, 2023, March 30, 2024, and June 29, 2024 have been restated as a result of the Company’s identification, during fiscal year 2024, of goods and services primarily relating to specific milestone achievements being expensed prior to the time that the corresponding milestones were achieved. This resulted in the acceleration of the recognition of cost of revenue. Given that the Company recognizes revenue on a percentage of completion basis, this resulted in the acceleration of recognition of revenue. Additionally, the Company identified errors in its revenue recognition related to cost overruns on certain deployments that will not be billable, which additionally impacted System revenue. Further, the Company identified, during fiscal year 2024, a classification error within equity, which was corrected as part of the aforementioned restatement. The restated unaudited condensed consolidated financial statement line items are indicated as “Restated” in the unaudited selected quarterly financial data. See Note 3, Restatement of Previously Issued Unaudited Condensed Consolidated Financial Statements for further discussion. Business Combination The Business Combination was accounted for as a reverse recapitalization as Legacy Warehouse was determined to be the accounting acquirer under FASB ASC Topic 805, Business Combinations . This determination was primarily based on Legacy Warehouse comprising the ongoing operations of the combined entity, Legacy Warehouse's senior management comprising the majority of the senior management of the combined company, and the prior shareholders of Legacy Warehouse owning a majority of the voting power of the combined entity. Accordingly, for accounting purposes, the financial statements of the combined entity upon consummation of the Business Combination represented a continuation of the financial statements of Legacy Warehouse with the merger being treated as the equivalent of Legacy Warehouse issuing stock for the net assets of SVF 3, accompanied by a recapitalization. Operations prior to the Business Combination are presented as those of Legacy Warehouse in future reports of the combined entity. The recapitalization had no effect on reported net loss and comprehensive loss, cash flows, total assets, or members' deficit as previously reported. See Note 4, Mergers and Acquisitions, for additional information. The Business Combination resulted in an umbrella partnership corporation (“Up-C”) structure, which is often used by partnerships and limited liability companies (operating as partnerships) undertaking an initial public offering. The Up-C structure allowed Legacy Warehouse equity holders (the “Legacy Warehouse Holders”) to retain their equity ownership in Symbotic Holdings, an entity that is classified as a partnership for U.S. federal income tax purposes, and provides potential future tax benefits for Symbotic when the Legacy Warehouse Holders ultimately redeem their pass-through interests for shares of Class A Common Stock in Symbotic Inc. Under the terms of the Tax Receivable Agreement (“TRA”), 85% of these potential future tax benefits realized by Symbotic Inc. as a result of such redemptions will be paid to certain Legacy Warehouse Holders (the “TRA Holders”). Noncontrolling Interests Noncontrolling interests represent the portion of Symbotic Inc. that the Company controls and consolidates but does not own. The noncontrolling interest was created as a result of the Business Combination by issuing non-economic shares to the prior investors in Legacy Warehouse. The Company recognizes each noncontrolling holder’s respective share of the estimated fair value of the net assets at the date of formation or acquisition. Noncontrolling interests are subsequently adjusted for the noncontrolling holder’s share of additional contributions, distributions and their share of the net earnings or losses of each respective consolidated entity. The Company allocates net income or loss to noncontrolling interests based on the weighted average ownership interest during the period. The net income or loss attributable to noncontrolling interests is reflected in the Consolidated Statements of Operations. The Company does not recognize a gain or loss on transactions with a consolidated entity in which it does not own 100% of the equity, but the Company reflects the difference in cash received or paid from the noncontrolling interests and carrying amount as additional paid-in capital. Class V-1 and Class V-3 shares are exchangeable, along with common units of Symbotic Holdings, into an equal number of the Company’s Class A Common Stock. Class A Common Stock issued upon exchange of a holder’s noncontrolling interest is accounted for at the carrying value of the surrendered limited partnership interest and the difference between the carrying value and the fair value of the Class A Common Stock issued is recorded to additional paid-in-capital. Variable Interest Entities The Company may enter into strategic investments or other investments or arrangements that are considered variable interest entities (“VIE”). If the Company is a primary beneficiary of a VIE, it is required to consolidate the entity. To determine if the Company is the primary beneficiary of a VIE, the Company evaluates whether it has (i) the power to direct the activities that most significantly impact the VIE’s economic performance, and (ii) the obligation to absorb losses or the right to receive benefits from the VIE that could potentially be significant to the VIE. The assessment of whether the Company is the primary beneficiary of its VIE investments requires significant assumptions and judgments. VIEs that are not consolidated are accounted for under the measurement alternative, equity method, amortized cost, or other appropriate methodology based on the nature of the interest held. Use of Estimates The preparation of consolidated financial statements in conformity with GAAP requires management to make estimates, judgments, and assumptions that affect the reported amounts of assets, liabilities, revenue, and expenses, and the amounts disclosed in the related notes to the consolidated financial statements. Actual results and outcomes may differ materially from management’s estimates, judgments, and assumptions. Significant estimates, judgments, and assumptions used in these financial statements include, but are not limited to, those related to revenue, useful lives and realizability of long-lived assets, accounting for income taxes and related valuation allowances, and stock-based compensation. Estimates are periodically reviewed in light of changes in circumstances, facts, and experience. Estimates and assumptions about future events and their effects cannot be determined with certainty and therefore require the exercise of judgment. As of the date of issuance of these financial statements, the Company is not aware of any specific event or circumstance that would require it to update its estimates, assumptions, and judgments or revise the carrying value of its assets or liabilities. These estimates may change as new events occur and additional information is obtained and will be recognized in the consolidated financial statements as soon as they become known. Actual results could differ from those estimates and any such differences may be material to the Company’s financial statements. Operating Segments The Company operates as one operating segment. Operating segments are defined as components of an enterprise for which separate financial information is regularly evaluated by the chief operating decision maker (“CODM”), which is the Company’s Chief Executive Officer, in deciding how to allocate resources and assess performance. The Company’s CODM evaluates the Company’s financial information and resources and assesses the performance of these resources on a consolidated basis. The Company is not organized by market and is managed and operated as one business. A single management team that reports to the chief executive officer comprehensively manages the entire business. Accordingly, the Company does not accumulate discrete financial information with respect to separate divisions and does not have separate operating or reportable segments. Since the Company operates in one operating segment, all required financial segment information can be found in the consolidated financial statements. Cash, Cash Equivalents, and Marketable Securities Cash and cash equivalents consist of cash and highly liquid investments that are readily convertible into cash and have original maturities of three months or less at the date of purchase. The Company invests its excess cash primarily in money market funds or demand deposit accounts of major financial institutions. Accordingly, the Company’s cash and cash equivalents are subject to minimal credit and market risk. The Company’s cash and cash equivalents are carried at cost, which approximates fair value. Marketable securities consist of U.S. Treasury securities. Securities having remaining maturities of more than three months at the date of purchase and less than one year from the date of the balance sheet are classified as short-term, and those with maturities of more than one year from the date of the balance sheet are classified as long-term in the consolidated balance sheets. The Company classifies its debt investments with readily determinable market values as available-for-sale. These investments are classified as investments on the consolidated balance sheets and are carried at fair market value, with unrealized gains and losses considered to be temporary in nature reported as accumulated other comprehensive loss, a separate component of stockholders’ equity. The Company reviews all investments for reductions in fair value that are other-than-temporary. When such reductions occur, the cost of the investment is adjusted to fair value through recording a loss on investments in the consolidated statements of operations. Gains and losses on investments are calculated on the basis of specific identification. Investments are considered to be impaired when a decline in fair value below cost basis is determined to be other-than-temporary. The Company periodically evaluates whether a decline in fair value below cost basis is other-than-temporary by considering available evidence regarding these investments including, among other factors: the duration of the period that, and extent to which, the fair value is less than cost basis; the financial health of, and business outlook for the issuer, including industry and sector performance and operational and financing cash flow factors; overall market conditions and trends and the Company’s intent and ability to retain its investment in the security for a period of time sufficient to allow for an anticipated recovery in market value. Once a decline in fair value is determined to be other-than-temporary, a write-down is recorded and a new cost basis in the security is established. Presentation of Restricted Cash Restricted cash consists of collateral required for a credit card processing program and a U.S. customs bond. The short-term or long-term classification is determined in accordance with the required amount of time the cash is to be held as collateral, which is short-term for less than 12 months, and long-term for greater than 12 months from the balance sheet date. The following table summarizes the end-of-period cash and cash equivalents from the Company’s Consolidated Balance Sheets and the total cash, cash equivalents, and restricted cash as presented on the accompanying Consolidated Statements of Cash Flows (in thousands): Year Ended September 28, 2024 September 30, 2023 September 24, 2022 Cash and cash equivalents $ 727,310 $ 258,770 $ 353,457 Restricted cash classified in: Prepaid expenses and other current assets 870 — — Other assets 2,174 2,148 — Cash, cash equivalents, and restricted cash shown in the statement of cash flows $ 730,354 $ 260,918 $ 353,457 Accounts Receivable Accounts receivable consists primarily of trade receivables from customers. The Company estimates the current expected credit losses for accounts receivable based on the aging of the receivables, customer financial statements, historical collection experience, existing economic conditions, and other available information. The Company had no current expected credit losses at September 28, 2024, September 30, 2023, and September 24, 2022. Concentrations of Credit Risk and Significant Customers Financial instruments that potentially expose the Company to concentrations of credit risk consist primarily of cash and cash equivalents and accounts receivable. The Company’s cash and cash equivalents are generally held with large financial institutions. Although the Company’s deposits may exceed federally insured limits, the financial institutions that the Company uses have high investment-grade credit ratings and, as a result, the Company believes that, as of September 28, 2024, its risk relating to deposits exceeding federally insured limits was not significant. The Company has no significant off-balance sheet risk such as foreign exchange contracts, options contracts, or other hedging arrangements. The Company believes its credit policies are prudent and reflect normal industry terms and business risk. The Company generally does not require collateral from its customers and generally requires payment 30 days from the invoice date. For the years ended September 28, 2024, September 30, 2023, and September 24, 2022, there was one customer that accounted for 10% or more of total revenue. The following table represents this customers’ aggregate percent of total revenue. Year Ended September 28, 2024 September 30, 2023 September 24, 2022 Customer A 86.9 % 88.4 % 94.4 % At September 28, 2024, one customer accounted for over 10% of the Company’s accounts receivable balance, and two customers accounted for over 10% of the Company’s accounts receivable balance at September 30, 2023. The following table represents these customers’ aggregate percent of total accounts receivable. The symbol “n/a” indicates that such customer’s accounts receivable balance at the period indicated within the table did not exceed 10% of the Company’s accounts receivable balance. September 28, 2024 September 30, 2023 Customer A 92.8 % 86.6 % Customer B n/a 10.3 % Aggregate Percent of Total Accounts Receivable 92.8 % 96.9 % The concentration in the volume of business transacted with these customers may lead to a material impact on the Company’s results from operations if a total or partial loss of the business relationship were to occur. As of the date of issuance of these financial statements, the Company is not aware of any specific event or circumstance which would result in a material adverse impact to its results of operations or liquidity and financial condition. Volume of Business The Company has concentration in the volume of purchases it conducts with its suppliers. For the fiscal year ended September 28, 2024, there were two suppliers that accounted for greater than 10% of total purchases, and the aggregate purchases from those two suppliers amounted to $343.0 million. For the fiscal year ended September 30, 2023, there was one supplier that accounted for greater than 10% of total purchases, and the aggregate purchases from that supplier amounted to $164.8 million. Fair Value Measurements The Company’s financial instruments consist of cash and cash equivalents, marketable securities, accounts receivable, and accounts payable. The carrying amounts of these financial instruments approximate their fair value due to their short-term nature. Derivative Instruments The Company entered into warrant agreements and a development and supply agreement with a supplier that, subject to meeting certain conditions, entitles the Company to acquire a fixed number of shares of the supplier during a period of time set forth in the warrant agreements. The warrants are accounted for as a derivative instrument under ASC Topic 815, Derivatives and Hedging . Inventories Inventories are stated at the lower of cost or net realizable value. Cost approximates actual cost on a first-in, first-out basis. Adjustments to reduce the cost of inventory to its net realizable value are made, if required, for estimated excess, obsolete, or impaired balances. At the point of the loss recognition, a new, lower cost basis for that inventory is established, and subsequent changes in facts and circumstances do not result in the restoration or increase in that newly established cost basis. Property and Equipment and Internal Use Software Property and equipment include purchases of items with a per-unit value greater than $2,000 and an estimated useful life greater than one year. Property and equipment are recorded at cost upon acquisition. Depreciation is computed using the straight-line method and depreciation expense is allocated between cost of revenue, research and development expenses, and selling, general, and administrative expenses on the statements of operations over the following estimated useful lives: Estimated Useful Life Computer equipment and software, furniture and fixtures, and test and other equipment 3 - 5 years Internal use software 5 years Leasehold improvements Shorter of estimated useful life or remaining term of the lease Expenditures that improve or extend the life of an asset are capitalized while repairs and maintenance expenditures are expensed as incurred. The Company periodically reviews the estimated useful lives of property and equipment. Changes to the estimated useful lives are recorded prospectively from the date of the change. As assets are retired or sold, the related cost and accumulated depreciation are removed from the accounts, and any resulting gain or loss is included in loss from operations. The Company capitalizes certain internal and external costs incurred to acquire or create internal use software. Capitalized costs include external consulting fees, payroll and payroll-related costs and stock-based compensation for employees who are directly associated with, and who devote time to, the Company’s internal use software projects. Capitalization begins when the planning stage is complete and the Company commits resources to the software project; capitalization continues during the application development stage and ceases when the software has been tested and is ready for its intended use. Costs incurred during the planning, training, and post-implementation stages of the software development life cycle are expensed as incurred. Capitalized internal use software is included in property, plant, and equipment and is depreciated over 5 years once development is complete. For capitalized internal use software costs which meet the criteria of a hosting arrangement that is a service contract, such as the Company’s costs capitalized related to its ERP implementation project, these costs are capitalized to prepaid expenses and other current assets on the Company’s consolidated balance sheets. Refer to Note 9, Property and Equipment for further discussion of these costs. Acquired Intangible Assets and Long-Lived Assets Acquired intangible assets consist of developed technology, customer relationships, and trademarks. Acquired intangible assets are amortized on a straight-line basis over their estimated useful lives. The Company periodically evaluates the recoverability of its long-lived assets, such as property and equipment and intangible assets, whenever events or changes in circumstances indicate that the carrying amount of an asset may not be fully recoverable. If circumstances require a long-lived asset or asset group to be tested for impairment, then assets are required to be grouped and evaluated at the lowest level for which there are identifiable cash flows that are largely independent of the cash flows of other groups of assets. If the carrying amount of the assets exceeds the expected future undiscounted net cash flows to be generated by the assets, then an impairment charge is recognized to the extent the carrying amount of the asset exceeds its fair value. No impairment losses were recognized in the years ended September 28, 2024 and September 24, 2022 and $0.1 million impairment losses were recognized in the year ended September 30, 2023. Leases The Company determines if an arrangement is a lease at its inception. When the arrangements include lease and non-lease components, the Company separates them and does not account for them as a single lease component. Leases with an initial term of less than 12 months are not reported on the balance sheet, but rather recognized as lease expense on a straight-line basis over the lease term. Arrangements may include options to extend or terminate the lease arrangement. These options are included in the lease term used to establish right-of-use (“ROU”) assets and lease liabilities when it is reasonably certain they will be exercised. The Company will reassess expected lease terms based on changes in circumstances that indicate options may be more or less likely to be exercised. The Company has lease arrangements that include variable rental payments. The future variability of these payments and adjustments are unknown and therefore are not included in minimum rental payments used to determine the ROU assets and lease liabilities. The Company has lease arrangements where it makes separate payments to the lessor based on the lessor’s common area maintenance expenses, property and casualty insurance costs, property taxes assessed on the property, and other variable expenses. Variable rental payments are recognized in the period in which their associated obligation is incurred. As most of the Company’s lease arrangements do not provide an implicit interest rate, an incremental borrowing rate is applied in determining the present value of future payments. The Company’s incremental borrowing rate is selected based upon information available at the lease commencement date and represents the Company’s estimate of an interest rate that it would be able to obtain from a lender to borrow, on a collateralized basis, over a similar term to obtain an asset of similar value in a similar economic environment. The ROU assets are reported as “Other long-term assets” and lease liabilities are reported as “Other current liabilities” and “Other long-term liabilities” on the consolidated balance sheets. Operating lease expense is recognized on a straight-line basis over the lease term and is included in “Selling, general, and administrative expenses” in the consolidated statements of operations. Variable lease expense is included in “Selling, general, and administrative expenses” in the consolidated statements of operations. Revenue Recognition Revenue is recognized in accordance with the five-step model set forth by Accounting Standards Update (“ASU”) 2014-09, Revenue from Contracts with Customers (“Topic 606”), which involves identification of the contract, identification of performance obligations in the contract, determination of the transaction price, allocation of the transaction price to the previously identified performance obligations, and revenue recognition as the performance obligations are satisfied. The Company generates revenue through its design and installation of supply chain automation systems (the “Systems”) to automate customers’ depalletizing, storage, selection, and palletization warehousing processes. The Systems have both a hardware component and an essential software component that enables the system to be programmed to operate within specific customer environments. The Company enters into contracts with customers that can include promises to (1) design and install the System, (2) provide software maintenance and support related to the System, and (3) assist customers in operating the System. These promises are generally distinct and accounted for as separate performance obligations. As a result, each customer contract may contain multiple performance obligations. The Company determines whether performance obligations are distinct based on whether the customer can benefit from the product or service on its own or together with other resources that are readily available and whether the product or service is separately identifiable from other products and services in the contract. The Company has identified the following distinct performance obligations in its contracts with customers: 1. Systems : The Company designs, assembles, and installs modular hardware systems and performs configuration of essential software. Systems include the delivery of hardware and an essential software component, sold as either a perpetual or term-based on-premise license, that automate customers’ depalletizing, storage, selection, and palletization warehousing processes. The modular hardware and essential software are each not capable of being distinct because a customer cannot benefit from the hardware or software on their own. Accordingly, they are treated as a single performance obligation. Fees for systems are typically fixed or cost-plus fixed fee amounts that are due based on the achievement of a variety of milestones beginning at contract inception through final acceptance. The substantial majority of the Company’s software component is sold as a perpetual on-premise license; however, the Company does sell an immaterial amount of term-based on-premise licenses. 2. Software maintenance and support : Software maintenance and support refer to support services that provide the customer with technical support, updates, and upgrades to the software license. Fees for the software maintenance and support services are typically payable in advance on a quarterly, or annual basis over the term of the software maintenance and support service contract, which term can range from one 3. Operation services : The Company provides the customer with assistance operating the System and ensuring user experience is optimized for efficiency and effectiveness. Fees for operation services are typically invoiced to customers on a time and materials basis monthly in arrears or using a fixed fee structure. Also included in Operation Services is revenue generated from the sales of spare parts to customers as needed to service their System. The Company recognizes revenue upon transfer of control of promised goods or services in a contract with a customer, generally as title and risk of loss pass to the customer, in an amount that reflects the consideration the Company expects to receive in exchange for those products or services. Revenue is recognized only to the extent that it is probable that a significant reversal of revenue will not occur and when collection is considered probable. In instances where the timing of revenue recognition differs from the timing of invoicing, the Company has determined its contracts do not include a significant financing component. Taxes collected from customers, which are subsequently remitted to governmental authorities, are excluded from revenue. Shipping and handling costs billed to customers are included in revenue and the related costs are included in cost of revenue when incurred. The Company presents amounts collected from customers for sales and other taxes net of the related amounts remitted. For contracts that contain multiple performance obligations, the transaction price is allocated to each performance obligation based on the relative observable standalone selling price when available. If an observable standalone selling price is not available, the Company estimates the standalone selling price of each performance obligation, which is generally based on an expected cost plus a margin approach. The design, assembly, and installation of a System includes substantive customer-specified acceptance criteria that allow the customer to accept or reject Systems that do not meet the customer’s specifications. When the Company cannot objectively determine that acceptance criteria will be met upon contract inception, revenue relating to Systems is deferred and recognized at a point in time upon final acceptance from the customer. If acceptance can be reasonably certain upon contract inception, revenue is recognized over time based on an input method, using a cost-to-cost measure of progress. Under this method, revenue is recorded based on the ratio of costs incurred over total estimated contract costs. This method provides a faithful depiction of the transfer of the System to the customer because the costs incurred represent the Company’s inputs towards satisfying the performance obligation. Systems revenue is predominantly recognized over time. Contract costs are incurred over a period of time, which can span multiple years, and the estimation of these costs requires management’s judgment. Due to the nature of the work required to be performed on the Systems and the Company’s reliance on the availability and cost of materials required to be procured from third party vendors to build the systems, the estimation of total revenue and cost at completion is complex, subject to many variables, and requires significant judgment on a contract-by-contract basis. As part of this process, the Company reviews information including, but not limited to, any outstanding key contract matters, progress towards completion and the related program schedule, identified risks and opportunities and the related changes in estimates of revenue and costs. Changes in estimates of net sales, cost of sales, and the related impact to operating profit are recognized on a cumulative catch-up basis, which recognizes the cumulative effect of the profit changes on current and prior periods based on a performance obligation’s percentage of completion in the current period. The transaction price allocated to the software maintenance and support services is recognized ratably as revenue over the term of the related contract. The transaction price allocated to operation services is recognized as revenue over time as

Accounting Changes and Error Corrections [Abstract]
Restatement of Previously Issued Unaudited Condensed Consolidated Financial Statements (Unaudited)	Restatement of Previously Issued Unaudited Condensed Consolidated Financial Statements (Unaudited) As described in Item 4.02 of the Company’s Current Report on Form 8-K filed with the SEC on November 18, 2024, on November 18, 2024, the Audit Committee of the Board of Directors of the Company, after discussions with the Company’s management, determined that the Company’s unaudited condensed consolidated financial statements included in each of the Company’s Quarterly Reports on Form 10-Q for the periods ending December 30, 2023 (the “Q1 2024 Form 10-Q”), March 30, 2024 (the “Q2 2024 Form 10-Q”), and June 29, 2024 (the “Q3 2024 Form 10-Q”, and together with the Q1 2024 Form 10-Q and Q2 2024 Form 10-Q, the “2024 Form 10-Qs”), filed with the SEC on February 8, 2024, May 7, 2024, and July 31, 2024, respectively, should no longer be relied upon. As described in Item 4.02 of the Company’s Current Report on Form 8-K/A filed with the SEC on November 27, 2024, on November 25, 2024, the Company identified errors in its revenue recognition related to cost overruns on certain deployments that will not be billable, which additionally impacted the Company’s unaudited condensed consolidated financial statements included in the Q1 2024 Form 10-Q and the Q2 2024 Form 10-Q. The Company, on the recommendation of the Audit Committee of the Company’s Board of Directors, determined to also correct these errors in the previously issued unaudited interim financial statements for the second and third quarters of fiscal year 2024 that were previously filed in the Fiscal 2024 Form 10-Qs (the “Restatement”). The restatement of the 2024 Form 10-Qs is being made in connection with the Company’s identification, during fiscal year 2024, of goods and services, primarily relating to specific milestone achievements, being expensed prior to the time that the corresponding milestones were achieved. This resulted in the acceleration of the recognition of cost of revenue. Given that the Company recognizes revenue on a percentage of completion basis, this resulted in the acceleration of recognition of revenue. Additionally, errors were identified in the Company’s revenue recognition related to cost overruns on certain deployments that will not be billable, which additionally impacted System revenue. Further, the Company identified, during fiscal year 2024, a classification error within equity, which was corrected as part of the Restatement.

Contract Balances The following table provides information about accounts receivable, unbilled accounts receivable, and contract liabilities from contracts with customers (in thousands): September 28, 2024 September 30, 2023 Accounts receivable $ 201,548 $ 69,206 Unbilled accounts receivable $ 218,233 $ 121,149 Contract liabilities $ 805,547 $ 787,227 The change in the opening and closing balances of the Company’s accounts receivable primarily results from the increase in customer system implementations in the current fiscal year as well as the timing of when customer payments are due. The change in the opening and closing balances of the Company’s contract liabilities primarily results from the timing difference between the Company’s performance and customer payments. The Company’s performance obligations are typically satisfied over time as work is performed. Payment from customers can vary and is often received in advance of satisfaction of the performance obligations, resulting in a contract liability balance. For the year ended September 24, 2022, the ending balance of accounts receivable, unbilled accounts receivable, and contract liabilities was $3.4 million, $101.8 million, and $425.7 million, respectively. During the years ended September 28, 2024 and September 30, 2023, the Company recognized $723.2 million and $387.6 million, respectively, of the contract liability balance at the beginning of the period as revenue upon transfer of the products or services to customers.

As a result, certain headcount reductions were necessary, and the Company recognized $2.3 million of expense associated with these actions, which is included within selling, general, and administrative expenses on the Consolidated Statements of Operations for the year ended September 30, 2023. The charges related to these actions were completed within the fiscal year ended September 30, 2023.

Prior to the close of the Business Combination, the Company's financial reporting predecessor, Legacy Warehouse, was treated as a pass-through entity for tax purposes and no provision, except for certain foreign subsidiaries, was made in the consolidated financial statements for income taxes. Any income tax items for the periods prior to the close of the Business Combination are related to the applicable subsidiary companies that are subject to foreign income tax. Symbotic Holdings is a limited liability company that is treated as a partnership for U.S. federal income tax purposes and for most applicable state and local income tax purposes. As a partnership, Symbotic Holdings is not subject to U.S. federal and certain state and local income taxes. Any taxable income or loss generated by Symbotic Holdings is passed through to and included in the taxable income or loss of its members, including the Company, on a pro rata basis, subject to applicable tax regulations. The Company is subject to U.S. federal income taxes, in addition to state and local income taxes, with respect to its allocable share of any taxable income or loss of Symbotic Holdings. The Company's foreign subsidiaries are subject to income tax in its local jurisdictions. The Company accounts for income taxes using the asset and liability method, which requires the recognition of deferred tax assets and liabilities for the estimated future tax consequences attributable to temporary differences between the consolidated financial statement carrying amounts of existing assets and liabilities and their respective tax base. Deferred tax assets and liabilities are determined on the basis of the differences between the consolidated financial statements and tax basis of assets and liabilities using enacted tax rates in effect for the year in which the temporary differences are expected to be settled or recovered. Changes in deferred tax assets and liabilities are recorded in the provision for income taxes. In assessing the realizability of deferred tax assets, the Company considers whether it is more likely than not that some portion or all of the deferred tax assets will be realized. The ultimate realization of deferred tax assets is dependent upon the generation of future taxable income during the periods in which those temporary differences become deductible. The Company considers the scheduled reversal of deferred tax liabilities, projected future income, and tax planning strategies in making this assessment. Valuation Allowance The Company has established a valuation allowance related to domestic and foreign deferred tax assets on deductible temporary differences, tax losses, and tax credit carryforwards. Due to a change in circumstances during the year ended September 28, 2024, the Company is recording an additional valuation allowance as it relates to Canada. As a result, the Company’s ending valuation allowance as of the year ended September 28, 2024 is $690.2 million. The remaining valuation allowance at September 28, 2024 of $690.2 million consists of $679.8 million in the United States and $10.4 million in foreign jurisdictions. The change in the valuation allowance in fiscal year 2024 of $203.3 million predominantly relates to the Company’s investment in Symbotic Holdings LLC, tax receivable agreement, and tax carryforward attributes. Activity related to the valuation allowance for the periods presented was as follows (in thousands): For the year ended September 28, 2024 September 30, 2023 September 24, 2022 Beginning balance $ 486,920 $ 168,308 $ 12,608 Recorded to additional paid-in capital 208,629 315,425 152,985 Recorded to other comprehensive income — — — Recorded to income tax expense (5,318) 3,187 2,715 Ending balance $ 690,231 $ 486,920 $ 168,308 Net Operating Losses As of September 28, 2024, the Company had U.S. federal net operating loss carryforwards of $155.1 million and gross state net operating loss carryforwards of $183.3 million. U.S. federal and certain state net operating losses generated in 2018 and beyond have no expiration. The remaining state net operating losses expire at various dates through 2043. As of September 28, 2024, the Company had Canadian net operating loss (“NOL”) carryforwards of approximately $26.2 million federal and $0.3 million provincial. The Canadian NOL carryforwards expire in various years through 2039 and are subject to review and possible adjustment by the applicable taxing authorities. Utilization of the domestic federal or Canadian NOL carryforwards may be subject to annual limitations due to ownership changes that have occurred previously or that could occur in the future. The Company has not completed any studies to determine if any of these events have occurred that would result in such limitations. Accordingly, further limitations could arise upon the completion of such studies. As of September 28, 2024, United States income taxes have not been provided on accumulated but undistributed earnings of foreign subsidiaries as the Company intends to permanently reinvest. Uncertain Tax Positions The Company accounts for uncertain tax positions using a more likely than not threshold for recognizing and resolving uncertain tax positions. The Company evaluates uncertain tax positions on an annual basis and adjusts the level of the liability to reflect any subsequent changes in the relevant facts surrounding the uncertain positions. For the years ended September 28, 2024 and September 30, 2023, the Company had no unrecognized tax benefits. Tax Receivable Agreement

Fair Value Disclosures [Abstract]
Fair Value Measures	Fair Value Measures The fair value measurement accounting standards establish a framework for measuring fair value and expand disclosures about fair value measurements. The standard does not require any new fair value measurements; rather, it applies to other accounting pronouncements that require or permit fair value measurements. Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability in the principal or most advantageous market in an orderly transaction between market participants on the measurement date. This pronouncement also establishes a three-level hierarchy, which requires an entity to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value. The valuation hierarchy is based upon the transparency of inputs to the valuation of an asset or liability on the measurement date. The three levels are defined as follows: Level 1 – inputs to the valuation methodology are quoted prices (unadjusted) for an identical asset or liability in an active market Level 2 – inputs to the valuation methodology include quoted prices for a similar asset or liability in an active market or model-derived valuations in which all significant inputs are observable for substantially the full term of the asset or liability Level 3 – inputs to the valuation methodology are unobservable and significant to the fair value measurement of the asset or liability The following table presents the Company’s financial assets measured and recorded at fair value on a recurring basis using the above input categories as of September 28, 2024 and September 30, 2023 (in thousands): Year Ended September 28, 2024 September 30, 2023 Level 1 Level 2 Level 3 Total Level 1 Level 2 Level 3 Total Assets: Money market funds $ 712,958 $ — $ — $ 712,958 $ 219,945 $ — $ — $ 219,945 U.S. Treasury Securities — — — — — 286,736 — 286,736 Warrant fair value — 12,308 — 12,308 — — — — Total assets $ 712,958 $ 12,308 $ — $ 725,266 $ 219,945 $ 286,736 $ — $ 506,681 The Company had no liabilities measured and recorded at fair value on a recurring basis as of September 28, 2024 and September 30, 2023. The Company considers all highly liquid investments purchased with an original maturity of three months or less to be cash equivalents. The fair value of the Company’s investments in certain money market funds is their face value and such instruments are classified as Level 1 and are included in cash and cash equivalents on the consolidated balance sheets. At September 28, 2024, the fair value of the warrant issued as described in Note 15, Derivative Instruments, is classified as Level 2 and at September 30, 2023, U.S. Treasury securities were classified as Level 2. Level 2 securities are priced by pricing vendors. These pricing vendors utilize the most recent observable market information in pricing these securities or, if specific prices are not available for these securities, use other observable inputs like market transactions involving identical or comparable securities.

Derivative Instruments and Hedging Activities Disclosure [Abstract]
Derivative Instruments	Derivative Instruments During fiscal year 2024, the Company entered into warrant agreements and a development and supply agreement with a supplier which, subject to meeting certain conditions, will entitle the Company to acquire a fixed number of shares of the supplier during the period of time set forth in the warrant agreements. The warrants will vest in a series of tranches, at a specified price per share, upon meeting certain development and production based milestones. If, and when, the relevant milestone is reached, the corresponding tranche of warrant will become exercisable up until the expiration date of the warrants in May 2044. The warrants are accounted for as a derivative under ASC 815, Derivatives and Hedging , as a result of certain net settlement provisions in the warrant agreements. The Company reports the warrants at their fair values within “other assets” in its condensed consolidated balance sheets and changes in the fair value of the warrants are recognized in “other income, net” on its condensed consolidated statements of operations. The day-one value attributable to the other side of the warrants is reported within “other liabilities” in the Company’s condensed consolidated balance sheets and will be amortized over the life of the applicable development and production milestones as determined in the development and supply agreement.

As there is no defined period of time stated within these aircraft time-sharing agreements, the Company does not consider these to meet the definition of a lease, and as such, records payments in the period in which the obligation for the payment is incurred. The Company incurred expense of $1.1 million, $0.9 million, and $0.7 million related to usage of the aircrafts for the years ended September 28, 2024, September 30, 2023, and September 24, 2022, respectively.

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	Commitments and Contingencies Purchase Obligations The Company has contractual obligations to purchase goods or services, which specify significant terms, including fixed or minimum quantities to be purchased and fixed minimum, or variable price provisions. The majority of the purchase commitments covered by these arrangements are for periods of less than one year and aggregate to approximately $1.3 billion as of September 28, 2024. Lease Commitments The Company leases certain of its facilities under operating leases expiring in various years through 2030.

Warranty The Company provides a limited warranty on its System and has established a reserve for warranty obligations based on estimated warranty costs. The reserve is included as part of “accrued expenses and other current liabilities” and “other liabilities” in the accompanying consolidated balance sheets. Activity related to the warranty accrual was as follows (in thousands): Year Ended September 28, 2024 September 30, 2023 September 24, 2022 Balance at beginning of period $ 18,948 $ 9,004 $ 3,735 Provision 18,773 16,833 7,329 Warranty usage (5,786) (6,889) (2,060) Balance at end of period $ 31,935 $ 18,948 $ 9,004 Legal Matters The Company is subject from time to time to various claims, lawsuits and other legal and administrative proceedings. Some of these claims, lawsuits and other proceedings may involve highly complex issues that are subject to substantial uncertainties, and could result in damages, fines and penalties, non-monetary sanctions or relief. The Company recognizes provisions for claims or pending litigation when it is determined that an unfavorable outcome is probable, and the amount of loss can be reasonably estimated. Due to the inherent uncertain nature of litigation, the ultimate outcome or actual cost of settlement may materially vary from estimates. SEC Request for Information The Company has been responding to requests for information from the SEC relating to an investigation by the SEC of alleged violations by the Company of Rule 21F-17, which prohibits actions to impede an individual from communicating directly with the SEC staff about a possible securities law violation. The Company intends to continue to defend this matter vigorously and cannot predict the outcome of this investigation. Securities Class Actions On August 14, 2024, a putative class action captioned Fox v. Symbotic Inc. et al., Case No. 24-cv-12090 was filed in the United States District Court for the District of Massachusetts by an alleged holder of the Company’s common stock. The complaint asserts claims for violations of federal securities laws against the Company and two of its officers on the grounds that, among other things, the Company made false and/or misleading statements related to its expected earnings for the third quarter of fiscal year 2024. Based on these allegations, the plaintiff brings claims seeking unspecified damages, attorneys’ fees, expert fees, and other costs and relief on behalf of herself and a putative class of persons who purchased the Company’s stock between May 6, 2024 and July 29, 2024. On September 11, 2024, the court entered a stipulation staying the Company’s deadline to respond to the complaint until after a lead plaintiff has been appointed pursuant to the Private Securities Litigation Reform Act. On October 15, 2024, four alleged shareholders filed motions seeking to be appointed as lead plaintiff. As of November 7, 2024, one alleged shareholder has withdrawn her motion for appointment as lead plaintiff, and two others have filed papers stating that they do not oppose the competing motion of the movant who claimed the largest losses, Dr. Seshagiri Rao Kalapala, and his selection of Levi & Korsinsky, LLP as lead counsel. As of December 3, 2024, the court has not yet ruled on the pending lead plaintiff motions. On December 3, 2024, a putative class action captioned Decker v. Symbotic Inc. et al., Case No. 24-cv-12976 was filed in the United States District Court for the District of Massachusetts by an alleged purchaser of the Company’s common stock. The complaint asserts claims for violations of federal securities laws against the Company and three of its officers on the grounds that the Company made false and/or misleading statements related to its revenue recognition and the effectiveness of its disclosure controls and procedures. Based on these allegations, the plaintiff brings claims seeking unspecified damages, attorneys’ fees, expert fees, and other costs and relief on behalf of himself and a putative class of persons who purchased the Company’s stock between February 8, 2024 and November 26, 2024. The Company intends to vigorously defend these cases. If a court ultimately determines that the Company is liable in either or both of these cases, the Company may be subject to substantial damages. The Company cannot predict with any degree of certainty the outcome of these matters or determine the extent of any potential liabilities. The Company also cannot provide an estimate of the possible loss or range of loss. Any adverse outcome in these matters could expose the Company to substantial damages that may have a material adverse impact on its operations and cash flows. Despite the potential for significant damages, the Company does not believe, based on currently available information, that the outcome of these proceedings will have a material adverse effect on its financial condition, although the outcome could be material to its operating results for any particular period, depending, in part, upon the operating results for such period. Shareholder Derivative Actions On October 2, 2024, two putative shareholder derivative actions captioned Austen v. Cohen et al., 24-cv-12522 and Kukreja v. Cohen et al., 24-cv-12523 were filed in the United States District Court for the District of Massachusetts by the Company’s alleged shareholders. The actions assert claims on behalf of the Company against certain senior officers and members of its board of directors for, among others, breach of fiduciary duty, unjust enrichment, and violations of federal securities laws based primarily on allegations that the defendants caused or allowed the Company to disseminate misleading and inaccurate information to shareholders in connection with the Company’s expected earnings for the third quarter of fiscal year 2024. The actions also contend that the defendants wasted corporate assets by exposing the Company to the securities class action lawsuit filed on August 14, 2024. The actions seek compensatory damages, changes to corporate governance and internal procedures, restitution, costs and attorneys’ fees, and other unspecified relief. On November 19 and November 20, 2024, the parties filed motions seeking to consolidate the two actions into a single matter, appoint lead plaintiffs’ counsel, and stay any obligation of the defendants to respond to the complaint based on the pendency of the related Fox v. Symbotic securities class action lawsuit (described above). The Company intends to vigorously defend these cases. If a court ultimately determines that the Company is liable, the Company may be subject to substantial damages. The Company cannot predict with any degree of certainty the outcome of this matter or determine the extent of any potential liabilities. The Company also cannot provide an estimate of the possible loss or range of loss. Any adverse outcome in this matter could expose the Company to substantial damages that may have a material adverse impact on its operations and cash flows. Despite the potential for significant damages, the Company does not believe, based on currently available information, that the outcome of this proceeding will have a material adverse effect on its financial condition, although the outcome could be material to its operating results for any particular period, depending, in part, upon the operating results for such period. Contingencies Liabilities for any loss contingencies arising from claims, assessments, litigation, fines, penalties, and other matters are recorded when it is probable that the liability has been incurred and the amount of the liability can be reasonably estimated. Legal costs associated with loss contingencies are expensed as incurred. As of September 28, 2024, the Company had made appropriate provisions related to such matters and does not believe that such matters will have a material adverse effect on the Company’s consolidated operations, financial position, or liquidity.

GreenBox is a VIE resulting from GreenBox’s lack of sufficient equity to finance its operations without additional subordinated financial support from both the Company and SoftBank. The consolidation of GreenBox is not required as the Company is not the primary beneficiary of this VIE as it does not have the power to direct the activities that most significantly impact GreenBox’s economic performance. Such power is conveyed through GreenBox’s board of directors and the Company does not have control over GreenBox’s board of directors. The Company’s recorded investments in the unconsolidated VIE and related estimated maximum exposure to loss are as follows (in thousands): September 28, 2024 Investments in Unconsolidated VIE Symbotic's Maximum Exposure to Loss GreenBox Systems LLC $ 81,289 $ 1,639,942 The Company calculated its maximum exposure to loss while considering its equity investment in the VIE, any amounts owed to the Company for services which may have been provided, and future funding commitments of $1,639.9 million. As of September 28, 2024, there is a $81.3 million carrying value of the VIE which represents the amount which the Company has invested in the VIE, net of the Company’s proportionate share of the VIE’s net loss. The Company’s maximum exposure to loss as displayed above does not take into consideration the VIE’s commitment under the Commercial Agreement to reimburse the Company in the event of a termination. If the VIE’s commitment under the Commercial Agreement was taken into consideration, there would be no maximum exposure to loss presented as the VIE’s commitment under the Commercial Agreement exceeds the Company’s future funding commitments.

Equity [Abstract]
Equity	Equity Prior to the Business Combination, the Company had authorized five classes of membership interests, consisting of a class of common units of the Company known as the Class A Common Units (the “Class A Units”), a class of preferred units of the Company known as the Class B Preferred Units (the “Class B Units”), a class of preferred units of the Company known as the Class B-1 Preferred Units (the “Class B-1 Units”), a class of preferred units of the Company known as the Class B-2 Preferred Units (the “Class B-2 Units”, and together with the Class B Units and the Class B-1 Units, the “Preferred Units”) and an additional class of common units of the Company to be granted to employees, officers, and directors pursuant to an incentive plan, known as the Class C Common Units (the “Class C Units” and, together with the Class A Units, the “Common Units,” and the Common Units together with the Preferred Units, the “Units”). Following the Business Combination, the Company has three classes of common stock, Class A Common Stock, Class V-1 Common Stock, and Class V-3 Common Stock (and together, the “Common Stock”). As the Business Combination was accounted for as a reverse recapitalization, all periods prior to the Business Combination were retroactively adjusted using the Exchange Ratio as stipulated by the Merger Agreement for the equivalent number of shares outstanding immediately after the Merger to effect the reverse recapitalization. The Class A Units were converted into Common Stock using an exchange ratio of 61.28 per share, the Class B Units were converted into Common Stock using an exchange ratio of 47,508,300.00 per share, the Class B-1 Units were converted into Common Stock using an exchange ratio of 24,031,400.00 per share, and the Class C Units were converted into Common Stock using an exchange ratio of 58.15 per share. This is presented within the consolidated statements of changes in redeemable preferred and common units and equity (deficit). Class A Common Stock The Company is authorized to issue 3,000,000,000 shares of Class A Common Stock, par value $0.0001 per share, of which 104,689,377 shares were issued and outstanding on September 28, 2024. Voting Rights Each holder of Class A Common Stock is entitled to one vote for each share of Class A Common Stock held of record by such holder on all matters submitted to a vote of the stockholders. Holders of Class A Common Stock will vote together with other holders of common stock as a single class on all matters (or, if any holders of any series of preferred stock are entitled to vote together with the holders of common stock, as a single class with the holders of such series of preferred stock). Notwithstanding the foregoing, the holders of shares of any series of common stock will be entitled to vote as a separate class upon any amendment to the Company’s certificate of incorporation (“Charter”) (including by merger, consolidation, reorganization or similar event) that would adversely alter or change the powers, preferences or special rights of such series of common stock. Except as expressly required by law, holders of common stock, as such, will not be entitled to vote on any amendment to the Charter (including any certificate of designation) that relates solely to the rights, powers, preferences (or the qualifications, limitations or restrictions thereof) or other terms of one or more outstanding series of preferred stock if the holders of such affected series are entitled, either separately or together with the holders of one or more other such series, to vote thereon pursuant to the Charter (including any certificate of designation) or pursuant to the Delaware General Corporation Law (“DGCL”). Dividend Rights Subject to the rights and preferences of any holders of any outstanding series of preferred stock, the holders of Class A Common Stock will be entitled to the payment of dividends and other distributions of cash, stock or property on the Class A Common Stock when, as and if declared by the board of directors in accordance with law. Liquidation Rights Subject to the rights and preferences of any holders of any shares of any outstanding series of preferred stock, in the event of any liquidation, dissolution or winding up, whether voluntary or involuntary, the Company’s funds and assets that may be legally distributed to its stockholders will be distributed among the holders of the then-outstanding Class A Common Stock pro rata in accordance with the number of shares of Class A Common Stock held by each such holder. Other Rights The holders of Class A Common Stock have no preemptive or conversion rights or other subscription rights. There are no redemption or sinking fund provisions applicable to the Class A Common Stock. The rights, preferences, and privileges of holders of the Class A Common Stock will be subject to those of the holders of any shares of the preferred stock the Company may issue in the future. Class V-1 Common Stock and Class V-3 Common Stock The Company is authorized to issue 1,000,000,000 shares of Class V-1 Common Stock and 450,000,000 shares of Class V-3 Common Stock, both which have a par value of $0.0001 and all of which were issued to the Legacy Warehouse unitholders in connection with the Closing of the Business Combination, as described in Note 4, Mergers and Acquisitions . As of September 28, 2024 there were 76,965,386 shares of Class V-1 and 404,309,196 shares of Class V-3 Common Stock outstanding. For the year ended September 28, 2024, the Legacy Warehouse unitholders exchanged 5,836,122 and 3,219,745 shares of Class V-1 and Class V-3 Common Stock, respectively, together with a corresponding number of New Symbotic Holdings Common Units, into an equal number of Class A Common Stock. The Company did not receive any proceeds as a result of this exchange. Voting Rights Each holder of Class V-1 Common Stock is entitled to one vote for each share of Class V-1 Common Stock held of record by such holder on all matters submitted to a vote of the stockholders, and each holder of Class V-3 Common Stock is entitled to three votes for each share of Class V-3 Common Stock held of record by such holder on all matters submitted to a vote of the stockholders. Holders of Class V-1 Common Stock and Class V-3 Common Stock will vote together with other holders of common stock as a single class on all matters (or, if any holders of any series of preferred stock are entitled to vote together with the holders of common stock, as a single class with the holders of such series of preferred stock). Notwithstanding the foregoing, the holders of shares of any series of common stock will be entitled to vote as a separate class upon any amendment to the Charter (including by merger, consolidation, reorganization or similar event) that would adversely alter or change the powers, preferences or special rights of such series of common stock. Except as expressly required by law, holders of common stock, as such, will not be entitled to vote on any amendment to the Charter (including any certificate of designation) that relates solely to the rights, powers, preferences (or the qualifications, limitations or restrictions thereof) or other terms of one or more outstanding series of preferred stock if the holders of such affected series are entitled, either separately or together with the holders of one or more other such series, to vote thereon pursuant to the Charter (including any certificate of designation) or pursuant to the DGCL. Dividend Rights Except as provided in the Charter with respect to certain stock adjustments, dividends of cash or property may not be declared or paid on shares of Class V-1 Common Stock or Class V-3 Common Stock. Liquidation Rights The holders of shares of Class V-1 Common Stock and Class V-3 Common Stock will not be entitled to receive any of the Company’s assets in the event of any voluntary or involuntary liquidation, dissolution or winding up of the Company. Other Rights The holders of Class V-1 Common Stock and Class V-3 Common Stock have no preemptive or other subscription rights. There are no sinking fund provisions applicable to the Class V-1 Common Stock or Class V-3 Common Stock. The rights, preferences and privileges of holders of the Class V-1 Common Stock and Class V-3 Common Stock will be subject to those of the holders of any shares of the preferred stock the Company may issue in the future. Subject to the terms of the New Symbotic Holdings LLC Agreement, holders of New Symbotic Holdings Common Units may cause the Company to redeem all or any portion of such holder’s New Symbotic Holdings Common Units, and in connection with such redemption, the Company may be required to deliver Class A common stock to such holder. Conversion of Class V-3 Common Stock Class V-3 Common Stock may convert into Class V-1 Common Stock in certain situations, including automatically seven years following the Business Combination. Transfer of Class V-1 Common Stock and Class V-3 Common Stock No holder of Class V-1 Common Stock or Class V-3 Common Stock may transfer such shares to any person unless such holder also simultaneously transfers an equal number of such holder’s New Symbotic Holdings Common Units to the same person in accordance with the terms of the New Symbotic Holdings LLC Agreement. Upon a transfer of New Symbotic Holdings Common Units in accordance with the New Symbotic Holdings LLC Agreement, an equal number of shares of Class V-1 Common Stock and/or Class V-3 Common Stock that correspond to such New Symbotic Holdings Common Units will automatically and simultaneously be transferred to the same transferee of such New Symbotic Holdings Common Units. Any attempted or purported transfer of shares of Class V-1 Common Stock and Class V-3 Common Stock in violation of the foregoing restrictions will be null and void. Cancellation of Class V-1 Common Stock and Class V-3 Common Stock In the event that any outstanding share of Class V-1 Common Stock or Class V-3 Common Stock ceases to be held directly or indirectly by a holder of a New Symbotic Holdings Common Units, such share will automatically be transferred to Symbotic and cancelled for no consideration. Preferred Stock The Company is authorized to issue 50,000,000 shares of undesignated preferred stock, par value $0.0001 per share, of which no shares were issued and outstanding on September 28, 2024. Legacy Warehouse Membership Interests Prior to the Business Combination and under the Legacy Warehouse Membership Interests, the Company was authorized to issue up to 6,426,208 Units in the aggregate, of which 5,997,632 are designated as Class A Units, one Unit is designated as a Class B Unit, two Units are designated as Class B-1 Units, two Units are designated as Class B-2 Units and 428,571 Units are designated as Class C Units. As of September 25, 2021, there were 5,997,632 Class A Units, one Class B Unit, one Class B-1 Unit and 428,571 Class C Units outstanding. As discussed above, these outstanding units were converted into Common Stock as part of the Business Combination during fiscal year 2022. During the period ended September 24, 2022, the Company received no member contributions from the holder of the Class B-1 Unit. The Company recorded a cumulative preferred return with respect to the holder of the Class B-1 Unit and B Unit of $8.1 million and $16.1 million, respectively, for the year ended September 24, 2022. The following conditions applied to the classes of membership interests authorized prior to the Business Combination: Voting Rights Each holder of Class A Units and Class C Units shall have the right to one vote per the Class A Unit or Class C Unit, respectively. Except as required by law, the Preferred Units do not have any voting rights. Preferred Return The holder of the Preferred Units shall be entitled to receive, in preference to the holders of the Class A Units and the Class C Units, a cumulative preferred return at a rate per annum of 5%, compounded annually, on the unreturned preferred capital of the holder’s Preferred Units (the “Preferred Return”). The Class A Units and Class C Units have no stated returns or dividends. Liquidation Rights In the event of liquidation, dissolution, or winding up of the Company, the five classes of membership interests rank in the following order of priority: the Class B-2 Units are the most senior, followed by Class B-1 Unit, then the Class B Unit, and then both the Class A Units and Class C Units treated as a single class. The holders of the Preferred Units are entitled to a liquidation preference equal to the sum of the Unreturned Preferred Capital (defined as the initial investment and subsequent contributions, less distributions, if any) and the applicable unpaid Preferred Return (collectively, the “Liquidation Preference”) in the order described in the preceding sentence, prior to any distribution to holders of the Class A Units and Class C Units. Upon the payment in full of the Liquidation Preference, any remaining assets available for distribution shall be distributed ratably to the holders of the Class A Units and Class C Units, however, for the Class C Units only to the extent that the value exceeds the applicable Hurdle Value (see Note 21, Stock-Based Compensation and Warrant Units ). Any remaining value that does not exceed the Hurdle Value for any particular Class C Unit shall be distributed to the holders of Class A Units (and any other Class C Units entitled to share in the distribution) based on their respective pro rata holdings of all such Class A (and Class C) Units. The Company classified its redeemable Preferred Units (Class B, B-1, and B-2 Units) as mezzanine equity, or outside of members’ deficit, because the units contain liquidation features that are not solely within the Company’s control. Redemption Rights Upon written notice by the holders of a majority of a class of Preferred Units, the Company shall redeem all of the outstanding Preferred Units of such class. The redemption price payable to each holder of the class of Preferred Units shall equal the Liquidation Preference of the Preferred Units being redeemed. The Class C Units are subject to a put feature that allow holders to redeem vested Class C Units, subject to certain terms and conditions (see Note 21, Stock-Based Compensation and Warrant Units

Earnings Per Share [Abstract]
Net Loss per Share	Net Loss per Share Basic earnings per share of Class A Common Stock is computed by dividing net loss attributable to common shareholders by the weighted-average number of shares of Class A Common Stock outstanding during the period. Diluted earnings per share of Class A Common Stock is computed by dividing net loss attributable to common shareholders adjusted for the assumed exchange of all potentially dilutive securities, by the weighted-average number of shares of Class A Common Stock outstanding adjusted to give effect to potentially dilutive elements. Since the Company incurred net losses for each of the periods presented, diluted net loss per share is the same as basic net loss per share. Prior to the Business Combination, the membership structure of Legacy Warehouse included units which shared in the profits and losses of Legacy Warehouse. The Company analyzed the calculation of earnings per unit for periods prior to the Business Combination and determined that it resulted in values that would not be meaningful to the users of these consolidated financial statements. Therefore, earnings per share information has not been presented for periods prior to the Business Combination on June 7, 2022. The basic and diluted earnings per share for the period ended September 24, 2022 represent only the period of June 8, 2022 to September 24, 2022. The following table sets forth reconciliations of the numerators and denominators used to compute basic and diluted earnings per share of Class A Common Stock (in thousands, except per share information): Year Ended September 28, 2024 September 30, 2023 September 24, 2022 Numerator - basic and diluted Net loss $ (84,672) $ (207,894) $ (139,089) Less: Net loss attributable to Warehouse Technologies LLC unitholders prior to the Business Combination — — (72,134) Less: Net loss attributable to the noncontrolling interest post Business Combination (71,182) (184,028) (60,092) Net loss attributable to common shareholders $ (13,490) $ (23,866) $ (6,863) Denominator - basic and diluted Weighted-average shares of Class A Common Stock outstanding 95,697,368 64,338,580 54,086,381 Loss per share of Class A Common Stock - basic and diluted $ (0.14) $ (0.37) $ (0.13) The Company’s Class V-1 Common Stock and Class V-3 Common Stock do not participate in the earnings or losses of the Company and are therefore not participating securities. As such, separate presentation of basic and diluted earnings per share of Class V-1 Common Stock and Class V-3 Common Stock under the two-class method has not been presented. The Company uses the treasury stock method and the average market price per share during the period for calculating any potential dilutive effect of the restricted stock units (“RSUs”), ESPP, and Warrant Units (defined below). The average stock price for the year ended September 28, 2024 was $38.79. For the year ended September 28, 2024, there were 5,636,703 potentially dilutive common stock equivalents related to the RSUs. The Warrant Units and ESPP shares were not included as they created an anti-dilutive effect.

Share-Based Payment Arrangement [Abstract]
Stock-Based Compensation and Warrant Units	Stock-Based Compensation and Warrant Units In June 2022, the Company’s stockholders approved the Symbotic Inc. 2022 Omnibus Incentive Compensation Plan (“2022 Plan”). The 2022 Plan allows for the issuance of stock options, stock appreciation rights, restricted shares, restricted stock units, dividend equivalent rights, and other equity-based or equity-like awards that the Compensation Committee of the Board of Directors determines to be consistent with the purposes of the 2022 Plan and the interests of the Company for up to 75,485,491 shares of Class A Common Stock to employees, directors, and consultants of the Company. Additionally, up to 8,500,000 shares may be issued in connection with the exchange of awards under the 2012 Value Appreciation Plan (described below) or the Amended and Restated 2018 Long Term Incentive Plan (“Legacy Plans”). The Company will no longer issue new awards under the Legacy Plans as all future grants will be issued under the 2022 Plan, or another equity plan that is approved by the Compensation Committee of the Board of Directors. Awards issued under the 2022 Plan have a maximum term of 10 years. The following two tables show stock-based compensation expense by award type and where the stock-based compensation expense is recorded in the Company’s consolidated statements of operations (in thousands): Year Ended September 28, 2024 September 30, 2023 September 24, 2022 RSUs (service-based and performance-based) $ 109,510 $ 152,791 $ 26,858 Employee stock purchase plan 2,698 1,436 — Total stock-based compensation expense $ 112,208 $ 154,227 $ 26,858 Effect of stock-based compensation expense on income by line item (in thousands): Year Ended September 28, 2024 September 30, 2023 September 24, 2022 Cost of revenue, Systems $ 12,529 $ 36 $ — Cost of revenue, Software maintenance and support 551 1,767 — Cost of revenue, Operation services 1,988 4,344 — Research and development 49,066 68,364 9,671 Selling, general, and administrative 48,074 79,716 17,187 Total stock-based compensation expense $ 112,208 $ 154,227 $ 26,858 Total stock-based compensation expense for the year ended September 28, 2024 decreased as compared to the year ended September 30, 2023 as a result of the issuance of restricted stock to our employees in August 2022 following the Business Combination with application of the graded-vesting method of expense recognition. There was no such grant in the same period of fiscal year 2023. RSUs represent the right to receive one share of the Company’s common stock upon vesting. RSUs are granted at the discretion of the Board of Directors, a committee thereof or, subject to defined limitations, the Chief Executive Officer of the Company, acting as a committee of one director, to whom such authority has been delegated. The Company has issued RSUs that vest based on the passage of time assuming continued service with the Company, and RSUs that vest only upon the achievement of defined performance metrics tied primarily to revenue and earnings targets. For RSUs with service-based vesting conditions, the fair value is calculated based on the Company’s closing stock price on the grant date, and the stock-based compensation expense is being recognized over the vesting period. Most RSUs with service-based vesting provisions vest in installments over a three-year period following the grant date. For RSUs with performance-based vesting conditions (“PSU”), management measures compensation expense based upon a review of the Company’s expected achievement against specified financial performance targets. Such compensation cost is being recorded to the extent management has deemed that such awards are probable of vesting based upon the expected achievement against the specified targets. On a periodic basis, management reviews the Company’s expected performance and adjusts the compensation cost, if needed, at such time. The following table summarizes the RSU activity for the periods presented: Shares Weighted Average Grant Date Fair Value Outstanding at September 24, 2022 12,365,587 $ 15.81 Granted 7,625,784 15.72 Vested (4,187,313) 15.78 Forfeited (2,920,043) 15.62 Outstanding at September 30, 2023 12,884,015 $ 15.81 Granted 3,102,298 44.44 Vested (6,863,457) 15.73 Forfeited (1,190,356) 20.14 Outstanding at September 28, 2024 7,932,500 $ 26.43 The total fair value of RSUs that vested during the years ended September 28, 2024, September 30, 2023 and September 24, 2022 was $295.5 million, $90.7 million, and $29.0 million, respectively. For the years ended September 28, 2024, September 30, 2023, and September 24, 2022, the weighted-average fair value of RSU awards granted was $44.44, $15.72, and $15.81 per share, respectively. As of September 28, 2024, 7.9 million RSUs were outstanding and unvested, with an aggregate value of $202.4 million and a weighted average remaining vesting period of approximately 0.82 years. These RSUs are expected to vest on various dates through 2027. The following table summarizes the PSU activity for the periods presented: Shares Weighted Average Grant Date Fair Value Outstanding at September 24, 2022 — Granted 337,986 $ 15.56 Vested — Forfeited — Outstanding at September 30, 2023 337,986 $ 15.56 Granted 235,292 48.38 Vested — Forfeited (73,226) 15.56 Outstanding at September 28, 2024 500,052 $ 31.10 Employee Stock Purchase Plan On June 3, 2022, the Company’s stockholders approved, and on June 7, 2022, the Company’s board of directors adopted the ESPP. The ESPP authorizes the issuance of up to a total of 2,702,515 shares of Class A Common Stock to participating employees, and allows eligible employees to purchase shares of Class A Common Stock at a 15% discount from the fair market value of the stock as determined on specific dates, which are typically at six-month intervals. The offering periods for the ESPP generally start on the first trading day on or after February 28th and August 31st of each year. However, the first offering period for the ESPP commenced on the first trading day after October 1, 2022 and ended on December 31, 2022, the second offering period commenced on the first trading day after January 1, 2023 and ended on June 30, 2023, the third offering period commenced on the first trading day after July 1, 2023 and ended on February 28, 2024, the fourth offering period commenced on March 1, 2024 and ended on August 31, 2024, and the fifth and current offering period commenced on the first trading day after September 1, 2024 and ends on February 28, 2025. The fair value of the ESPP is estimated using the Black-Scholes option-pricing model with the following assumptions: Year Ended September 28, 2024 September 30, 2023 Risk-free interest rate (%) 0.05 0.03 - 0.05 Expected term (years) 0.50 0.25 - 0.66 Volatility (%) 63.54 - 73.27 63.67 - 76.21 Expected dividends — — The interest rate is based on the U.S. Treasury bond rate at the date of grant with a maturity approximately equal to the expected term. The expected term was based on terms of the offering period. The expected volatility for the Company’s common stock is based on an average of the historical volatility of a peer group of similar public companies. The assumed dividend yield is based upon the Company’s expectation of not paying dividends in the foreseeable future. The fair value of the Company’s common stock is the closing price of the stock on the date the offering period starts. For the year ended September 28, 2024, 230,548 shares of common stock were issued to employees who participated in the plan with a weighted average purchase price of $24.00 per share for total cash proceeds of $5.5 million, net of taxes. For the year ended September 30, 2023, 225,788 shares of common stock were issued to employees who participated in the plan with a weighted average purchase price of $10.20 per share for total cash proceeds of $2.6 million, net of taxes. Class C Units Prior to the Business Combination, the Company periodically granted Class C Units to employees, officers, and directors which vest over a period of up to five years, as determined by the Board of Managers. Each issuance of Class C Units entitles its holder to share in the appreciation in the fair market value (“FMV”) of the Company from the date of issuance, subject to any preferences or priorities payable to the Preferred Units. The Board shall establish a “Hurdle Value”, which shall not be less than the FMV on the date of such issuance of such Class C Unit and such units shall share only in appreciation of the FMV in excess of the Hurdle Value. Any distributions made with respect to Class C Units that have not yet become vested are held in a separate account for the benefit of the holder of the unvested units until such time as the units vest. The Class C Units are subject to a put feature that allow holders to redeem vested Class C Units. The put feature requires the holder to hold the units for at least six months from the date the Class C Units vest to the earliest date the put feature can be exercised. Accordingly, since the holder is exposed to the economic risks and rewards of unit ownership, the Class C Units are treated as equity classified awards. However, because redemption of the Class C Units is outside of the control of the Company: (i) the Class C Units are classified outside of permanent members’ deficit, and (ii) the carrying value of Class C Units is adjusted to redemption value at each reporting period through a charge to members’ deficit (until such time as the Class C Units are redeemed or forfeited). As further described in Note 19, Equity , the Class C Units were converted into Common Stock upon consummation of the Business Combination. The following is a summary of Class C Units outstanding and vested immediately prior to the consummation of the Business Combination: Class C Balance at September 25, 2021 428,571 Granted 18,107 Redeemed — Forfeited (18,107) Balance at June 7, 2022 428,571 Vested at June 7, 2022 375,930 Valuation of Class C Units The fair value of Class C Units was determined by the Company’s Board of Managers based on enterprise valuations performed by management with the assistance of a third-party valuation firm. For fiscal year 2022 leading up to the Business Combination, the Company’s total equity value was determined using a combination of the income approach and market approach under the Hybrid Method. Under this approach, a probability-weighted expected return method was applied where two types of future event scenarios were considered: an IPO scenario and a non-IPO scenario for all other potential future exits. The relative probabilities between the future exit scenarios were based on an analysis of performance and market conditions at the time, including then-current IPO valuations of similarly situated companies and expectations as to the timing and likely prospects of future event scenarios. The resulting equity value was then allocated to outstanding equity instruments using an option pricing model. The fair value of each Class C Unit grant was estimated on the date of the award using a Black-Scholes option pricing model with the following assumptions: June 7, 2022 Dividend yield 0 % Volatility(a) 45.0 % Risk-free interest rate(b) 2.30 % Expected term (years)(c) 2.00 (a) The expected volatility is estimated based on the historical volatility of a select peer group of similar publicly traded companies for a term that is consistent with the expected term of the Class C Units. (b) The risk-free interest rate is based on the U.S. Treasury constant maturity interest rate whose term is consistent with the expected term of the Class C Units. (c) The expected term is based on estimated liquidity event timing as further described above. The fair value per unit for the Class C Units granted was determined to be the following for each of the periods presented: • $451.81 for the period December 26, 2021 through June 7, 2022 • $415.75 for the period September 26, 2021 through December 25, 2021 Value Appreciation Units The Company historically granted VAP Units to employees, officers, and directors that vested over a period of up to five years, as determined by the Board of Managers. No VAP Units were granted during the year ended September 24, 2022. Following the Business Combination and in the fourth quarter of fiscal year 2022, all outstanding VAP Units for 20 employees were converted into the Company’s restricted stock units. The Company issued 2,350,795 RSUs to the legacy VAP Unit holders. The conversion of the VAP Units into RSUs was treated as a modification in accordance with ASC 718, and resulted in a charge of $24.4 million to additional paid-in capital on the date of the modification. This included a step-up in grant date fair value charge of $0.7 million, which was principally due to the difference between the VAP Units grant date hurdle rates and the Company’s stock price as of the modification date. Prior to the Business Combination, to the extent vested and exercisable, each VAP Unit could be exercised for a cash payment equal to the appreciation in the FMV of 1/100th of a Class C Unit. The following exercisability triggers must be met before any vested award may be exercised, with the achievement of each trigger allowing one third of the vested award to be exercised: (i) the end of the first fiscal year in which the Company meets or exceeds annual revenue (on a cash accounting basis) of $100 million, (ii) the end of the first fiscal year in which the Company becomes cash flow positive, and (iii) the end of the first fiscal year in which the Company generates positive earnings before interest, taxes, depreciation, and amortization (“EBITDA”). The following is a summary of VAP Units outstanding which were converted to restricted stock units in the fourth quarter of fiscal year 2022: VAP Units Balance at September 25, 2021 4,039,620 Granted — Exercised (255,845) Forfeited (92,664) Balance at August 16, 2022 3,691,111 Converted to restricted stock units (3,691,111) Balance at September 24, 2022 — Because the VAP Units were settleable in cash, they were treated as liability classified awards. Accordingly, the carrying value of the liability was adjusted to fair value at each reporting period through a charge to earnings (until such time as the VAP Units are settled or forfeited). Further, the exercisability triggers noted above represent performance conditions that impact the vesting of the awards. Accordingly, compensation expense is not recognized until such time as the performance conditions are considered probable of achievement. As of the conversion date, the performance conditions relating to annual revenue and cash flows were considered probable of achievement. The performance condition relating to EBITDA was not considered probable of achievement for any of the periods presented and up to the date of conversion of the VAP Units to restricted stock units. The Company recognized $13.2 million as compensation expense associated with the VAP Units for the year ended September 24, 2022. Warrant Units GreenBox Warrant On July 23, 2023, in connection with the Commercial Agreement, the Company issued Sunlight the GreenBox Warrant to acquire up to an aggregate of 11,434,360 shares of the Company’s Class A Common Stock, subject to certain vesting conditions. The GreenBox Warrant had a grant date fair value of $19.90 per unit. The GreenBox Warrant may vest in connection with conditions defined by the terms of the GreenBox Warrant, as GreenBox makes additional expenditures to the Company in connection with the Framework Agreement. There are up to eight tranches based on increments of expenditures where approximately 1,429,295 additional shares may vest per tranche, subject to certain conditions defined by the terms of the GreenBox Warrant. Upon vesting, the shares may be acquired at an exercise price of $41.9719. The GreenBox Warrant contains customary anti-dilution, down-round, and change-in-control provisions. The right to purchase shares pursuant to the GreenBox Warrant expires 36 months following the end of the initial term of the Framework Agreement, which is July 23, 2027, or, if applicable, the extension term of the Framework Agreement, which is July 23, 2029. As of September 28, 2024, none of the GreenBox Warrant units had vested. Non-cash share-based payment expense associated with the GreenBox Warrant is recognized as vesting conditions are achieved, based on the grant date fair value of the warrants. The fair value of the GreenBox Warrant was determined as of the grant date in accordance with ASC Topic 718, Compensation – Stock Compensation , using the Monte Carlo simulation model. The Monte Carlo simulation model utilizes multiple input variables that determine the probability of satisfying the vesting conditions stipulated in the warrant agreement in a large number of simulated scenarios. Additionally, the Black-Scholes pricing model was applied to determine the fair value of the GreenBox warrant after vesting. Key assumptions for the Monte Carlo simulation and Black-Scholes models include risk-free interest rate and historical stock price volatility of peer company shares. The Black-Scholes assumptions utilized in determining the grant date fair value of the GreenBox Warrant after vesting are included in the following table: Selected Assumption Strike price $ 41.972 Volatility (a) 48.0% Risk-free interest rate (b) 4.44% Expected term (years) (c) 3.00 (a) The expected volatility is estimated based on the historical volatility of a select peer group of similar publicly traded companies for a term that is consistent with the expected term of the GreenBox Warrant. (b) The risk-free interest rate is based on the U.S. Treasury constant maturity interest rate whose term is consistent with the expected term of the GreenBox Warrant. (c) The expected term is based on the contractual term of the GreenBox Warrant. Walmart Warrants On April 30, 2021, in connection with its entry into a Subscription Agreement with Walmart, the Company issued Walmart warrants to acquire up to an aggregate of 714,022 shares of the Company’s Class A Units (the “Warrants”), subject to certain vesting conditions. Warrants equivalent to 6.5% of the Company’s outstanding and issuable Common Units, or 446,741 units, vested upon the signing of the Subscription Agreement, and had a grant date fair value of $60.44 per unit. Warrants equivalent to up to 3.5% of the Company’s outstanding and issuable Common Units, or 267,281 units, may vest in connection with conditions defined by the terms of the Warrant, as Walmart makes additional expenditures to the Company in connection with the Subscription Agreement, There are up to six tranches based on increments of additional expenditures where approximately 44,000 additional Warrants may vest per tranche. The Warrants had a grant date fair value of $60.44 per unit. Upon vesting, units may be acquired at an exercise price of $389.03. The warrant units contain customary anti-dilution, down-round, and change-in-control provisions. The right to purchase units in connection with the Warrant expires on April 30, 2031. Non-cash share-based payment expense associated with the warrant units is recognized as vesting conditions are achieved, based on the grant date fair value of the warrants. The fair value of the warrant units was determined as of the grant date in accordance with ASC 718 using the Black-Scholes pricing model. The Black-Scholes pricing model is based, in part, upon assumptions for which management is required to use judgment. The assumptions made for purposes of estimating fair value under the Black-Scholes pricing model for the Warrants were as follows: Selected Assumption Dividend yield 0 % Volatility(a) 43.0 % Risk-free interest rate(b) 1.65 % Expected term (years)(c) 10.00 (a) The expected volatility is estimated based on the historical volatility of a select peer group of similar publicly traded companies for a term that is consistent with the expected term of the Warrants. (b) The risk-free interest rate is based on the U.S. Treasury constant maturity interest rate whose term is consistent with the expected term of the Warrants. (c) The expected term is based on the contractual term of the Warrants. In December 2021, Walmart elected to gross exercise the 446,741 vested Warrant Units for $173.8 million. As a result of this gross exercise, 446,741 Class A Common Units of Legacy Warehouse were issued to Walmart, which represented a 6.5% ownership in the Company’s outstanding and issuable Common Units. On May 20, 2022, in connection with its entry into the 2nd A&R MAA, Walmart's remaining 267,281 Warrant Units vested in accordance with the terms referenced above. Upon vesting, Walmart elected to gross exercise the 267,281 vested Warrant Units for $104.0 million. As a result of this gross exercise, 267,281 Class A Common Units of Legacy Warehouse were issued to Walmart, which represented, together with the December 2021 gross exercise, a combined total of 10.0% ownership in the Company's then outstanding and issuable Common Units. Also in connection with its entry into the 2nd A&R MAA with Walmart, the Company issued Walmart a new warrant to acquire up to an aggregate of 258,972 Legacy Warehouse Class A Units (“May 2022 Warrant”), subject to certain vesting conditions. The May 2022 Warrants had a grant date fair value of $224.45. In connection with the Closing, the May 2022 Warrant was converted into a new warrant to acquire up to an aggregate of 15,870,411 common units of Symbotic Holdings (“June 2022 Warrant” and, the common units of Symbotic Holdings issuable thereunder, the “Warrant Units”). The June 2022 Warrant vested in the second quarter of fiscal year 2023, as the installation commencement date for certain Systems which the Company is installing in Walmart's 42 regional distribution centers had occurred. In December 2023, Walmart elected to gross exercise the vested warrants for $158.7 million. As a result of this gross exercise, 15,870,411 shares of Class V-1 Common Stock were issued to Walmart. Non-cash share-based payment expense associated with the June 2022 Warrant is recognized as vesting conditions are achieved, based on the grant date fair value of the warrants. The fair value of the June 2022 Warrant was determined as of the grant date in accordance with ASC Topic 718, Compensation – Stock Compensation , using the Black-Scholes pricing model. The Black-Scholes pricing model is based, in part, upon assumptions for which management is required to use judgment. The assumptions made for purposes of estimating fair value under the Black-Scholes pricing model for the June 2022 Warrant were as follows: Selected Assumption Dividend yield 0% Volatility (a) 40.0% Risk-free interest rate (b) 2.80% Expected term (years) (c) 5.00 (a) The expected volatility is estimated based on the historical volatility of a select peer group of similar publicly traded companies for a term that is consistent with the expected term of the June 2022 Warrant. (b) The risk-free interest rate is based on the U.S. Treasury constant maturity interest rate whose term is consistent with the expected term of the June 2022 Warrant. (c) The expected term is based on the contractual term of the June 2022 Warrant. The following table summarizes the Company’s stock warrant activity for the year ended September 28, 2024: Warrant Units Outstanding and unvested at September 24, 2022 258,972 Granted 11,434,360 Vested (258,972) Outstanding and unvested at September 30, 2023 11,434,360 Granted — Vested — Outstanding and unvested at September 28, 2024 11,434,360 The amount of provision for warrants recorded as a reduction of transaction price during the twelve months ended September 28, 2024 was $227.5 million. As of September 28, 2024, the total warrant value related to the unvested GreenBox Warrants is $227.5 million and the remaining term of the agreement is 1.8 years.

Summary of Significant Accounting Policies (Policies)	12 Months Ended
	Sep. 28, 2024
Accounting Policies [Abstract]
Basis of Presentation	The consolidated financial statements have been prepared in U.S. dollars, in accordance with accounting principles generally accepted in the United States of America (“GAAP”). The accompanying consolidated financial statements include the accounts of the Company and its wholly-owned subsidiaries and majority-owned subsidiaries. The consolidated financial statements include 100% of the accounts of wholly-owned and majority-owned subsidiaries and the ownership interest of the minority investors are recorded as a non-controlling interest in a subsidiary. All intercompany balances and transactions have been eliminated in consolidation.
Foreign Currency Translation	Certain transactions of the Company and its subsidiaries are denominated in currencies other than the functional currency. Foreign currency transaction losses were less than $0.1 million for the year ended September 28, 2024, and less
Fiscal Period	The Company operates and reports using a 52-53 week fiscal year ending on the last Saturday closest to September 30. Accordingly, the Company’s fiscal quarters end on the last Saturday that falls closest to the last day of the third month of each quarter. The fiscal year ended September 28, 2024 was a 52-week period, the fiscal year ended September 30, 2023 was a 53-week period, and the fiscal year ended September 24, 2022 was a 52-week period.
Restatement of Previously Issued Unaudited Condensed Consolidated Financial Statements	As described in Note 3, Restatement of Previously Issued Unaudited Condensed Consolidated Financial Statements , the Company’s unaudited condensed consolidated financial statements as of and for the fiscal quarters ended December 30, 2023, March 30, 2024, and June 29, 2024 have been restated as a result of the Company’s identification, during fiscal year 2024, of goods and services primarily relating to specific milestone achievements being expensed prior to the time that the corresponding milestones were achieved. This resulted in the acceleration of the recognition of cost of revenue. Given that the Company recognizes revenue on a percentage of completion basis, this resulted in the acceleration of recognition of revenue. Additionally, the Company identified errors in its revenue recognition related to cost overruns on certain deployments that will not be billable, which additionally impacted System revenue. Further, the Company identified, during fiscal year 2024, a classification error within equity, which was corrected as part of the aforementioned restatement. The restated unaudited condensed consolidated financial statement line items are indicated as “Restated” in the unaudited selected quarterly financial data. See Note 3, Restatement of Previously Issued Unaudited Condensed Consolidated Financial Statements for further discussion.
Business Combination	The Business Combination was accounted for as a reverse recapitalization as Legacy Warehouse was determined to be the accounting acquirer under FASB ASC Topic 805, Business Combinations . This determination was primarily based on Legacy Warehouse comprising the ongoing operations of the combined entity, Legacy Warehouse's senior management comprising the majority of the senior management of the combined company, and the prior shareholders of Legacy Warehouse owning a majority of the voting power of the combined entity. Accordingly, for accounting purposes, the financial statements of the combined entity upon consummation of the Business Combination represented a continuation of the financial statements of Legacy Warehouse with the merger being treated as the equivalent of Legacy Warehouse issuing stock for the net assets of SVF 3, accompanied by a recapitalization. Operations prior to the Business Combination are presented as those of Legacy Warehouse in future reports of the combined entity. The recapitalization had no effect on reported net loss and comprehensive loss, cash flows, total assets, or members' deficit as previously reported. See Note 4, Mergers and Acquisitions, for additional information. The Business Combination resulted in an umbrella partnership corporation (“Up-C”) structure, which is often used by partnerships and limited liability companies (operating as partnerships) undertaking an initial public offering. The Up-C structure allowed Legacy Warehouse equity holders (the “Legacy Warehouse Holders”) to retain their equity ownership in Symbotic Holdings, an entity that is classified as a partnership for U.S. federal income tax purposes, and provides potential future tax benefits for Symbotic when the Legacy Warehouse Holders ultimately redeem their pass-through interests for shares of Class A Common Stock in Symbotic Inc. Under the terms of the Tax Receivable Agreement (“TRA”), 85% of these potential future tax benefits realized by Symbotic Inc. as a result of such redemptions will be paid to certain Legacy Warehouse Holders (the “TRA Holders”).
Noncontrolling Interests	Noncontrolling interests represent the portion of Symbotic Inc. that the Company controls and consolidates but does not own. The noncontrolling interest was created as a result of the Business Combination by issuing non-economic shares to the prior investors in Legacy Warehouse. The Company recognizes each noncontrolling holder’s respective share of the estimated fair value of the net assets at the date of formation or acquisition. Noncontrolling interests are subsequently adjusted for the noncontrolling holder’s share of additional contributions, distributions and their share of the net earnings or losses of each respective consolidated entity. The Company allocates net income or loss to noncontrolling interests based on the weighted average ownership interest during the period. The net income or loss attributable to noncontrolling interests is reflected in the Consolidated Statements of Operations. The Company does not recognize a gain or loss on transactions with a consolidated entity in which it does not own 100% of the equity, but the Company reflects the difference in cash received or paid from the noncontrolling interests and carrying amount as additional paid-in capital. Class V-1 and Class V-3 shares are exchangeable, along with common units of Symbotic Holdings, into an equal number of the Company’s Class A Common Stock. Class A Common Stock issued upon exchange of a holder’s noncontrolling interest is accounted for at the carrying value of the surrendered limited partnership interest and the difference between the carrying value and the fair value of the Class A Common Stock issued is recorded to additional paid-in-capital.
Variable Interest Entities	The Company may enter into strategic investments or other investments or arrangements that are considered variable interest entities (“VIE”). If the Company is a primary beneficiary of a VIE, it is required to consolidate the entity. To determine if the Company is the primary beneficiary of a VIE, the Company evaluates whether it has (i) the power to direct the activities that most significantly impact the VIE’s economic performance, and (ii) the obligation to absorb losses or the right to receive benefits from the VIE that could potentially be significant to the VIE. The assessment of whether the Company is the primary beneficiary of its VIE investments requires significant assumptions and judgments. VIEs that are not consolidated are accounted for under the measurement alternative, equity method, amortized cost, or other appropriate methodology based on the nature of the interest held.
Use of Estimates	The preparation of consolidated financial statements in conformity with GAAP requires management to make estimates, judgments, and assumptions that affect the reported amounts of assets, liabilities, revenue, and expenses, and the amounts disclosed in the related notes to the consolidated financial statements. Actual results and outcomes may differ materially from management’s estimates, judgments, and assumptions. Significant estimates, judgments, and assumptions used in these financial statements include, but are not limited to, those related to revenue, useful lives and realizability of long-lived assets, accounting for income taxes and related valuation allowances, and stock-based compensation. Estimates are periodically reviewed in light of changes in circumstances, facts, and experience.
Operating Segments	The Company operates as one operating segment. Operating segments are defined as components of an enterprise for which separate financial information is regularly evaluated by the chief operating decision maker (“CODM”), which is the Company’s Chief Executive Officer, in deciding how to allocate resources and assess performance. The Company’s CODM evaluates the Company’s financial information and resources and assesses the performance of these resources on a consolidated basis. The Company is not organized by market and is managed and operated as one business. A single management team that reports to the chief executive officer comprehensively manages the entire business. Accordingly, the Company does not accumulate discrete financial information with respect to separate divisions and does not have separate operating or reportable segments. Since the Company operates in one operating segment, all required financial segment information can be found in the consolidated financial statements.
Cash and Cash Equivalents	Cash and cash equivalents consist of cash and highly liquid investments that are readily convertible into cash and have original maturities of three months or less at the date of purchase. The Company invests its excess cash primarily in money market funds or demand deposit accounts of major financial institutions. Accordingly, the Company’s cash and cash equivalents are subject to minimal credit and market risk. The Company’s cash and cash equivalents are carried at cost, which approximates fair value.
Marketable Securities	Marketable securities consist of U.S. Treasury securities. Securities having remaining maturities of more than three months at the date of purchase and less than one year from the date of the balance sheet are classified as short-term, and those with maturities of more than one year from the date of the balance sheet are classified as long-term in the consolidated balance sheets. The Company classifies its debt investments with readily determinable market values as available-for-sale. These investments are classified as investments on the consolidated balance sheets and are carried at fair market value, with unrealized gains and losses considered to be temporary in nature reported as accumulated other comprehensive loss, a separate component of stockholders’ equity. The Company reviews all investments for reductions in fair value that are other-than-temporary. When such reductions occur, the cost of the investment is adjusted to fair value through recording a loss on investments in the consolidated statements of operations. Gains and losses on investments are calculated on the basis of specific identification. Investments are considered to be impaired when a decline in fair value below cost basis is determined to be other-than-temporary. The Company periodically evaluates whether a decline in fair value below cost basis is other-than-temporary by considering available evidence regarding these investments including, among other factors: the duration of the period that, and extent to which, the fair value is less than cost basis; the financial health of, and business outlook for the issuer, including industry and sector performance and operational and financing cash flow factors; overall market conditions and trends and the Company’s intent and ability to retain its investment in the security for a period of time sufficient to allow for an anticipated recovery in market value. Once a decline in fair value is determined to be other-than-temporary, a write-down is recorded and a new cost basis in the security is established.
Presentation of Restricted Cash	Restricted cash consists of collateral required for a credit card processing program and a U.S. customs bond. The short-term or long-term classification is determined in accordance with the required amount of time the cash is to be held as collateral, which is short-term for less than 12 months, and long-term for greater than 12 months from the balance sheet date.
Accounts Receivable	Accounts receivable consists primarily of trade receivables from customers. The Company estimates the current expected credit losses for accounts receivable based on the aging of the receivables, customer financial statements, historical collection experience, existing economic conditions, and other available information.
Concentration of Credit Risk and Significant Customers	Financial instruments that potentially expose the Company to concentrations of credit risk consist primarily of cash and cash equivalents and accounts receivable. The Company’s cash and cash equivalents are generally held with large financial institutions. Although the Company’s deposits may exceed federally insured limits, the financial institutions that the Company uses have high investment-grade credit ratings and, as a result, the Company believes that, as of September 28, 2024, its risk relating to deposits exceeding federally insured limits was not significant. The Company has no significant off-balance sheet risk such as foreign exchange contracts, options contracts, or other hedging arrangements.
Fair Value Measurements	The Company’s financial instruments consist of cash and cash equivalents, marketable securities, accounts receivable, and accounts payable. The carrying amounts of these financial instruments approximate their fair value due to their short-term nature.
Derivative Instruments	The Company entered into warrant agreements and a development and supply agreement with a supplier that, subject to meeting certain conditions, entitles the Company to acquire a fixed number of shares of the supplier during a period of time set forth in the warrant agreements. The warrants are accounted for as a derivative instrument under ASC Topic 815, Derivatives and Hedging .
Inventories	Inventories are stated at the lower of cost or net realizable value. Cost approximates actual cost on a first-in, first-out basis. Adjustments to reduce the cost of inventory to its net realizable value are made, if required, for estimated excess, obsolete, or impaired balances. At the point of the loss recognition, a new, lower cost basis for that inventory is established, and subsequent changes in facts and circumstances do not result in the restoration or increase in that newly established cost basis.
Property and Equipment and Internal Use Software	Property and equipment include purchases of items with a per-unit value greater than $2,000 and an estimated useful life greater than one year. Property and equipment are recorded at cost upon acquisition. Expenditures that improve or extend the life of an asset are capitalized while repairs and maintenance expenditures are expensed as incurred. The Company periodically reviews the estimated useful lives of property and equipment. Changes to the estimated useful lives are recorded prospectively from the date of the change. As assets are retired or sold, the related cost and accumulated depreciation are removed from the accounts, and any resulting gain or loss is included in loss from operations.
Acquired Intangible Assets and Long-Lived Assets	Acquired intangible assets consist of developed technology, customer relationships, and trademarks. Acquired intangible assets are amortized on a straight-line basis over their estimated useful lives.
Leases	The Company determines if an arrangement is a lease at its inception. When the arrangements include lease and non-lease components, the Company separates them and does not account for them as a single lease component. Leases with an initial term of less than 12 months are not reported on the balance sheet, but rather recognized as lease expense on a straight-line basis over the lease term. Arrangements may include options to extend or terminate the lease arrangement. These options are included in the lease term used to establish right-of-use (“ROU”) assets and lease liabilities when it is reasonably certain they will be exercised. The Company will reassess expected lease terms based on changes in circumstances that indicate options may be more or less likely to be exercised. The Company has lease arrangements that include variable rental payments. The future variability of these payments and adjustments are unknown and therefore are not included in minimum rental payments used to determine the ROU assets and lease liabilities. The Company has lease arrangements where it makes separate payments to the lessor based on the lessor’s common area maintenance expenses, property and casualty insurance costs, property taxes assessed on the property, and other variable expenses. Variable rental payments are recognized in the period in which their associated obligation is incurred. As most of the Company’s lease arrangements do not provide an implicit interest rate, an incremental borrowing rate is applied in determining the present value of future payments. The Company’s incremental borrowing rate is selected based upon information available at the lease commencement date and represents the Company’s estimate of an interest rate that it would be able to obtain from a lender to borrow, on a collateralized basis, over a similar term to obtain an asset of similar value in a similar economic environment.
Revenue Recognition	Revenue is recognized in accordance with the five-step model set forth by Accounting Standards Update (“ASU”) 2014-09, Revenue from Contracts with Customers (“Topic 606”), which involves identification of the contract, identification of performance obligations in the contract, determination of the transaction price, allocation of the transaction price to the previously identified performance obligations, and revenue recognition as the performance obligations are satisfied. The Company generates revenue through its design and installation of supply chain automation systems (the “Systems”) to automate customers’ depalletizing, storage, selection, and palletization warehousing processes. The Systems have both a hardware component and an essential software component that enables the system to be programmed to operate within specific customer environments. The Company enters into contracts with customers that can include promises to (1) design and install the System, (2) provide software maintenance and support related to the System, and (3) assist customers in operating the System. These promises are generally distinct and accounted for as separate performance obligations. As a result, each customer contract may contain multiple performance obligations. The Company determines whether performance obligations are distinct based on whether the customer can benefit from the product or service on its own or together with other resources that are readily available and whether the product or service is separately identifiable from other products and services in the contract. The Company has identified the following distinct performance obligations in its contracts with customers: 1. Systems : The Company designs, assembles, and installs modular hardware systems and performs configuration of essential software. Systems include the delivery of hardware and an essential software component, sold as either a perpetual or term-based on-premise license, that automate customers’ depalletizing, storage, selection, and palletization warehousing processes. The modular hardware and essential software are each not capable of being distinct because a customer cannot benefit from the hardware or software on their own. Accordingly, they are treated as a single performance obligation. Fees for systems are typically fixed or cost-plus fixed fee amounts that are due based on the achievement of a variety of milestones beginning at contract inception through final acceptance. The substantial majority of the Company’s software component is sold as a perpetual on-premise license; however, the Company does sell an immaterial amount of term-based on-premise licenses. 2. Software maintenance and support : Software maintenance and support refer to support services that provide the customer with technical support, updates, and upgrades to the software license. Fees for the software maintenance and support services are typically payable in advance on a quarterly, or annual basis over the term of the software maintenance and support service contract, which term can range from one 3. Operation services : The Company provides the customer with assistance operating the System and ensuring user experience is optimized for efficiency and effectiveness. Fees for operation services are typically invoiced to customers on a time and materials basis monthly in arrears or using a fixed fee structure. Also included in Operation Services is revenue generated from the sales of spare parts to customers as needed to service their System. The Company recognizes revenue upon transfer of control of promised goods or services in a contract with a customer, generally as title and risk of loss pass to the customer, in an amount that reflects the consideration the Company expects to receive in exchange for those products or services. Revenue is recognized only to the extent that it is probable that a significant reversal of revenue will not occur and when collection is considered probable. In instances where the timing of revenue recognition differs from the timing of invoicing, the Company has determined its contracts do not include a significant financing component. Taxes collected from customers, which are subsequently remitted to governmental authorities, are excluded from revenue. Shipping and handling costs billed to customers are included in revenue and the related costs are included in cost of revenue when incurred. The Company presents amounts collected from customers for sales and other taxes net of the related amounts remitted. For contracts that contain multiple performance obligations, the transaction price is allocated to each performance obligation based on the relative observable standalone selling price when available. If an observable standalone selling price is not available, the Company estimates the standalone selling price of each performance obligation, which is generally based on an expected cost plus a margin approach. The design, assembly, and installation of a System includes substantive customer-specified acceptance criteria that allow the customer to accept or reject Systems that do not meet the customer’s specifications. When the Company cannot objectively determine that acceptance criteria will be met upon contract inception, revenue relating to Systems is deferred and recognized at a point in time upon final acceptance from the customer. If acceptance can be reasonably certain upon contract inception, revenue is recognized over time based on an input method, using a cost-to-cost measure of progress. Under this method, revenue is recorded based on the ratio of costs incurred over total estimated contract costs. This method provides a faithful depiction of the transfer of the System to the customer because the costs incurred represent the Company’s inputs towards satisfying the performance obligation. Systems revenue is predominantly recognized over time. Contract costs are incurred over a period of time, which can span multiple years, and the estimation of these costs requires management’s judgment. Due to the nature of the work required to be performed on the Systems and the Company’s reliance on the availability and cost of materials required to be procured from third party vendors to build the systems, the estimation of total revenue and cost at completion is complex, subject to many variables, and requires significant judgment on a contract-by-contract basis. As part of this process, the Company reviews information including, but not limited to, any outstanding key contract matters, progress towards completion and the related program schedule, identified risks and opportunities and the related changes in estimates of revenue and costs. Changes in estimates of net sales, cost of sales, and the related impact to operating profit are recognized on a cumulative catch-up basis, which recognizes the cumulative effect of the profit changes on current and prior periods based on a performance obligation’s percentage of completion in the current period. The transaction price allocated to the software maintenance and support services is recognized ratably as revenue over the term of the related contract. The transaction price allocated to operation services is recognized as revenue over time as the services are performed and costs are incurred. Typically, consideration is due from customers in advance or upon the achievement of billing milestones, the timing of which does not always align with the satisfaction of performance obligations, creating contract assets or contract liabilities. Contract assets primarily relate to the Company’s rights to consideration for work completed but not billed at the reporting date. Contract assets are transferred to accounts receivable when the rights become unconditional, which typically occurs within 12 months from the reporting date. Contract assets are presented as unbilled receivables in the consolidated balance sheets. Contract liabilities consist of deferred revenue and relate to the Company’s obligation to transfer goods and services in exchange for consideration already received or due from customers. Deferred revenue is recorded when the Company has a right to invoice or payments have been received for undelivered products or services, or in situations where revenue recognition criteria have not been met. Deferred revenue that will be recognized during the succeeding 12-month period is recorded as current deferred revenue, and the remaining portion is recorded as long-term deferred revenue. Costs to fulfill a contract are presented as deferred expenses on the consolidated balance sheets and consist of costs incurred by the Company to fulfill its obligations under a contract once it is obtained, but before transferring goods or services to the customer. These costs relate directly to a contract that the Company can specifically identify, are costs to generate or enhance resources of the Company that are used in satisfying performance obligations and are costs which are expected to be recovered. Accordingly, these costs are recognized on the consolidated balance sheets as an asset and are recognized consistent with the pattern of the transfer of the goods or services to which the asset relates. For all contracts, the Company recognizes anticipated contract losses as a charge to cost of revenue as soon as they become evident. There were no contract losses recorded in the consolidated statements of operations for the fiscal years ended September 28, 2024, September 30, 2023, and September 24, 2022. There were no anticipated contract losses recorded in accrued expenses on the consolidated balance sheets as of September 28, 2024 and September 30, 2023. The Company’s warehouse automation system generally provides for a limited warranty that promises customers that delivered products are as specified. The Company’s standard warranty provides for repair or replacement of the associated System parts during the warranty period. The Company records estimated warranty costs in the period the related revenue is recognized based on historical experience or expectations of future costs to repair or replace. Actual results could differ from these estimates, which could cause increases or decreases in warranty reserves in future periods.
Warrant Transactions	The warrant units granted to Walmart and the GreenBox Warrant are accounted for as equity instruments and measured in accordance with ASC 718, Compensation—Stock Compensation
Research and Development Expenses	Costs incurred in the research and development of the Company’s products are expensed as incurred, except for certain internal use software development costs eligible for capitalization as discussed above. Research and development costs include personnel, contracted services, materials, and indirect costs involved in the design and development of new products and services, as well as depreciation expense.
Selling, General and Administrative Expenses	Selling, general, and administrative expenses include all costs that are not directly related to satisfaction of customer contracts or research and development. Selling, general, and administrative expenses include items for the Company’s selling and administrative functions, such as sales, finance, legal, human resources, and information technology support. These functions include costs for items such as salaries and benefits and other personnel-related costs, maintenance and supplies, professional fees for external legal, accounting, and other consulting services, intangible asset amortization, and depreciation expense.
Stock-based Compensation	The Company recognizes compensation costs for all stock-based payment awards based upon the awards’ grant-date fair value. The stock-based payment awards include restricted stock units. For stock awards that contain only a service-based vesting feature, the Company recognizes compensation cost on a graded vesting basis over the award’s vesting period. For performance-based restricted stock awards that vest and become exercisable only upon achievement of specified performance conditions, the Company makes judgments and estimates each quarter about the probability that such performance conditions will be met or achieved. Any changes to those estimates that the Company makes from time to time may have a significant impact on the stock-based compensation expense recorded and could materially impact the Company’s results of operations. The Company recognizes the effect of pre-vesting forfeitures as they occur. The Company classifies stock-based compensation expense in its consolidated statements of operations in the same manner in which the award recipient’s salary and related costs are classified.
Income Taxes	As a result of the Business Combination, the Company was appointed as the sole managing member of Symbotic Holdings. Symbotic Holdings is a limited liability company that is treated as a partnership for U.S. federal income tax purposes and for most applicable state and local income taxes. Any taxable income or loss generated by Symbotic Holdings is passed through to and included in the taxable income or loss of its members, including the Company, on a pro rata basis, subject to applicable tax regulations. The Company is subject to U.S. federal income taxes, in addition to state and local income taxes, with respect to its allocable share of any taxable income or loss of Symbotic Holdings. Additionally, there are foreign subsidiaries of Symbotic Holdings that are subject to income tax in their local jurisdictions. Refer to Note 12, Income Taxes , for further details. The Company accounts for income taxes in accordance with ASC Topic 740, Accounting for Income Taxes (“ASC Topic 740”), which requires the recognition of tax benefits or expenses on temporary differences between the financial reporting and tax bases of its assets and liabilities by applying the enacted tax rates in effect for the year in which the differences are expected to reverse. Such net tax effects on temporary differences are reflected on the Company’s consolidated balance sheets as deferred tax assets and liabilities. Deferred tax assets are reduced by a valuation allowance when the Company believes that it is more-likely-than-not that some portion or all of the deferred tax assets will not be realized. ASC Topic 740 prescribes a two-step approach for the recognition and measurement of tax benefits associated with the positions taken or expected to be taken in a tax return that affect amounts reported in the financial statements. The Company has reviewed and will continue to review the conclusions reached regarding uncertain tax positions, which may be subject to review and adjustment at a later date based on ongoing analyses of tax laws, regulations and interpretations thereof. To the extent that the Company’s assessment of the conclusions reached regarding uncertain tax positions changes as a result of the evaluation of new information, such change in estimate will be recorded in the period in which such determination is made. The Company reports income tax-related interest and penalties relating to uncertain tax positions, if applicable, as a component of income tax expense.
Tax Receivable Agreement	In connection with the Business Combination, the Company entered into a Tax Receivable Agreement, which generally provides for the payment by the Company to the TRA Holders of their proportionate share of 85% of the tax savings, if any, in U.S. federal and state income tax that is realized by the Company (or are deemed to realize in certain circumstances) as a result of (i) the existing tax basis in certain assets of New Symbotic Holdings that is allocable to the relevant New Symbotic Holdings Common Units, (ii) any step-up in tax basis in New Symbotic Holdings’ assets resulting from the relevant Exchanges and certain distributions (if any) by New Symbotic Holdings and payments under the Tax Receivable Agreement, and (iii) tax benefits related to imputed interest deemed to be paid by the Company as a result of payments under the Tax Receivable Agreement. The Company records liabilities for amounts payable under the Tax Receivable Agreement in the period in which the payment is deemed to be probable. Further, payments under the Tax Receivable Agreement are only expected to be made in periods following the filing of a tax return in which the Company is able to utilize tax benefits described above to reduce its cash taxes paid to a taxing authority.
Emerging Growth Company	For the fiscal years ended September 30, 2023 and September 24, 2022, the Company was an emerging growth company (“EGC”), as defined in Section 2(a) of the Securities Act of 1933, as modified by the Jumpstart Our Business Startups Act of 2012 (the “JOBS Act”). Section 102(b)(1) of the JOBS Act exempts EGCs from being required to comply with new or revised financial accounting standards until private companies (that is, those that have not had a Securities Act registration statement declared effective or do not have a class of securities registered under the Securities Exchange Act of 1934, as amended (the “Exchange Act”)) are required to comply with the new or revised financial accounting standards. The JOBS Act provides that a company can elect to opt out of the extended transition period and comply with the requirements that apply to non-EGCs but any such an election to opt out is irrevocable. The Company had not elected to opt out of such extended transition period which means that when a financial accounting standard is issued or revised and it has different application dates for public or private companies, the Company, as an EGC, was allowed to adopt the new or revised standard at the time private companies adopt the new or revised standard. The Company was eligible to use this extended transition period under the JOBS Act until the earlier of the date it (i) is no longer an EGC or (ii) affirmatively and irrevocably opts out of the extended transition period provided in the JOBS Act. If any of the following conditions are met, then the Company ceases to be an EGC: (i) the end of the fiscal year in which total annual gross revenue exceeds $1.235 billion, (ii) the last day of the Company’s fiscal year following March 11, 2026 (the fifth anniversary of the date on which SVF 3 consummated the initial public offering of SVF 3), (iii) the date on which
Recently Issued Or Adopted Accounting Pronouncements	Recently Issued Or Adopted Accounting Pronouncements The Company has implemented all applicable accounting pronouncements that are in effect and there are no new accounting pronouncements that have been issued that would have a material impact on its financial position or results of operations.
