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. 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.
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 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.
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. 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 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. 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.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.
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. 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.
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.
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 to 15 years but, for a substantial majority of the Company’s software maintenance and support contracts, is 15 years. 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. The Company has not deferred sales commissions and other costs to obtain a contract because such amounts that would qualify for deferral are not material.
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. These instruments are classified in the consolidated statements of operations in accordance with ASC 606, Revenue from Contracts with Customers, and ASU 2019-08, Compensation—Stock Compensation (Topic 718) and Revenue from Contracts with Customers (Topic 606) (“ASU 2019-08”). For awards granted to a customer which are not in exchange for distinct goods or services, the fair value of the awards earned based on service or performance conditions is recorded as a reduction of the transaction price, in accordance with ASC 606. To determine the fair value of the warrants in accordance with ASC 718, the Company used pricing models based in part on assumptions for which management is required to use judgment. Based on the fair value of the awards, the Company determines the amount of warrant expense based on the customer’s pro-rata achievement of vesting conditions, which is recorded as a reduction to the transaction price.
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.

Summary of Significant Accounting Policies (Policies)

12 Months Ended

Sep. 28, 2024

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.

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

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.

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.

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 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.

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.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.

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.

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.

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.

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 to 15 years but, for a substantial majority of the Company’s software maintenance and support contracts, is 15 years.

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.

The Company has not deferred sales commissions and other costs to obtain a contract because such amounts that would qualify for deferral are not material.

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. These instruments are classified in the consolidated statements of operations in accordance with ASC 606, Revenue from Contracts with Customers, and ASU 2019-08, Compensation—Stock Compensation (Topic 718) and Revenue from Contracts with Customers (Topic 606) (“ASU 2019-08”). For awards granted to a customer which are not in exchange for distinct goods or services, the fair value of the awards earned based on service or performance conditions is recorded as a reduction of the transaction price, in accordance with ASC 606. To determine the fair value of the warrants in accordance with ASC 718, the Company used pricing models based in part on assumptions for which management is required to use judgment. Based on the fair value of the awards, the Company determines the amount of warrant expense based on the customer’s pro-rata achievement of vesting conditions, which is recorded as a reduction to the transaction price.

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

the Company has issued more than $1.0 billion in non-convertible debt during the preceding three-year period; or (iv) the end of the fiscal year in which the market value of the Company’s common stock held by non-affiliates exceeds $700 million as of the last business day of the most recently completed second fiscal quarter.

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.
