Summary of Significant Accounting Policies (Policies)	12 Months Ended
Summary of Significant Accounting Policies (Policies)	Sep. 27, 2025
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.
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	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 years ended September 27, 2025, September 28, 2024 and September 30, 2023, 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 27, 2025 was a 52-week period, the fiscal year ended September 28, 2024 was a 52-week period, and the fiscal year ended September 30, 2023 was a 53-week period.
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, valuation of business and identifiable net assets acquired, valuation of investments, 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.
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.
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.
Strategic Investments	Strategic investments consist of non-marketable equity investments of privately held companies in which the Company does not have a controlling interest. The Company may elect to apply the measurement alternative or the fair value option for investments without readily determinable fair values for which the Company does not have the ability to exercise significant influence. Under the measurement alternative, the non-marketable securities are carried at cost less any impairments, plus or minus adjustments resulting from observable price changes in orderly transactions for identical or similar investments of the same issuer. On a quarterly basis, the Company performs a qualitative assessment to evaluate whether the investment is impaired. If there are sufficient indicators that the fair value of the investment is less than the carrying value, the carrying value of the investment is reduced and an impairment is recorded in the consolidated statements of operations in other income (expense).
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 27, 2025, 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 weighted average 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, costs are capitalized to prepaid expenses and other current assets on the Company’s consolidated balance sheets.
Business Acquisitions	The Company allocates the fair value of purchase consideration to the tangible assets acquired, liabilities assumed, and intangible assets acquired based on their estimated fair values. The excess of the fair value of purchase consideration over the fair value of these identifiable assets and liabilities is recorded as goodwill. During the measurement period, which may be up to one year from the acquisition date, the Company may record adjustments to the fair value of these assets acquired and liabilities assumed with the corresponding offset to goodwill. Upon the conclusion of the final determination of the fair value of assets acquired or liabilities assumed, any subsequent adjustments are recorded to the consolidated statements of operations. Determining the fair value of the tangible assets acquired, liabilities assumed, and intangible assets requires management to make significant estimates and assumptions, especially with respect to intangible assets. Significant estimates in valuing certain intangible assets include, but are not limited to, cash flows that an asset is expected to generate in the future, technology migration curves, discount rates, and useful lives. While the Company uses its best estimates and judgments, the estimates are inherently uncertain and subject to refinement. Acquisition-related transaction costs are expensed as incurred.
Acquired Intangible Assets and Long-Lived Assets	Acquired intangible assets consist of developed technology. 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.
Goodwill	Goodwill represents the excess of cost over the fair value of the net tangible and identifiable intangible assets acquired in a business combination. Goodwill is not subject to amortization but is monitored annually for impairment or more frequently if there are indicators of impairment. The Company considers the following potential indicators of impairment: significant underperformance relative to historical or projected future operating results, significant changes in the Company’s use of acquired assets or the strategy of the Company’s overall business, significant negative industry or economic trends and a significant decline in the Company’s stock price for a sustained period. The Company performs its annual impairment test on the first day of its fourth fiscal quarter. The Company’s goodwill is evaluated at the consolidated level as it has been determined there is one operating segment comprised of one reporting unit. The Company performs a quantitative or qualitative assessment, which compares the fair value of the reporting unit with its carrying value. If the carrying amount of the reporting unit exceeds its fair value, an impairment loss is recognized. Based on the qualitative assessment performed on the first day of the fourth fiscal quarter, or June 29, 2025, no indicators of impairment existed, and as such, there was no impairment of goodwill as of June 29, 2025. There were no triggering events after the measurement date that may indicate impairment as of September 27, 2025. The Company did not carry a goodwill balance for the years ended September 28, 2024 and 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 incremental borrowing rate is derived from information available at the lease commencement date. To determine the estimated incremental borrowing rate, the Company uses publicly available credit ratings for peer companies. The Company estimates the incremental borrowing rate using yields for maturities that are in line with the duration of the lease payments. 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 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 and training services to customers as needed to service their System. The Company recognizes revenue as control of promised goods or services in a contract is transferred to the customer, in an amount that reflects the consideration the Company expects to receive in exchange for those products or services. The Company considers the contractual consideration payable by the customer and assesses variable consideration that may affect the total transaction price, including contractual discounts, changes in total System contract cost estimates, contract incentive payments, shipping fees, inflation adjustments, and other sources of variable consideration, when determining the transaction price of each contract. The Company accounts for all consideration payable to a customer as a reduction of revenue. Consideration payable to a customer may include cash amounts that the Company is obligated to pay or expects to pay a customer, as well as credits or other items that can be applied against amounts owed to the Company from the customer. Variable consideration 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. Certain contracts may provide the customer with a material right through a contingent promise or an option to acquire additional goods and services in the future. The Company accounts for the material right as a separate performance obligation where a portion of the transaction price is allocated based on the expected goods and services and the expected consideration if a customer exercises that material right. The transaction price allocated to the material right is then recognized as revenue over the period in which control over the goods and services underlying the material right is transferred to the customer. The Company identified a material right obligation in connection with the 2025 Walmart MAA to develop and produce APDs (further defined in Note 4, Revenue). 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. As customer acceptance can be reasonably certain upon contract inception, the Company recognizes revenue over time based on an input method. 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 Company has elected the right to invoice practical expedient for operation services where we are assisting customers with operating their System. Accordingly, the Company recognizes revenue based on actual costs incurred. Sales of spare parts and training services are recognized at a point in time upon transfer of title of the spare parts or occurrence of training services, respectively. Certain of the Company’s contracts contain variable consideration where additional amounts can be earned based on specified contract criteria. These amounts are included in the transaction price to the extent it is not probable there will be a significant reversal of revenue. 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 the contract 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 material contract losses recorded in the consolidated statements of operations for the fiscal years ended September 27, 2025, September 28, 2024, and September 30, 2023. There were no material anticipated contract losses recorded in accrued expenses on the consolidated balance sheets as of September 27, 2025 and September 28, 2024. The Company’s 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 Topic 718, Compensation—Stock Compensation. These instruments are classified in the consolidated statements of operations in accordance with ASC Topic 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 Topic 606. To determine the fair value of the warrants in accordance with ASC Topic 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 11, Income Taxes, for further details. The Company accounts for income taxes in accordance with ASC Topic 740, Accounting for Income Taxes, 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.
Recent Accounting Pronouncements	In November 2023, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2023-07, “Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures” (“ASU 2023-07”), which requires enhanced disclosures about significant segment expenses and introduces a reconciliation between segment revenue and segment profitability metrics. As required, the Company has adopted the standard in the current fiscal year and incorporated all expanded disclosure requirements in Note 21, Segment and Geographic Information. In December 2023, the FASB issued ASU 2023-09, “Income Taxes (Topic 740): Improvements to Income Tax Disclosures” (“ASU 2023-09”). ASU 2023-09 requires public entities, on an annual basis, to provide: a tabular rate reconciliation (using both percentages and reporting currency amounts) of (1) the reported income tax expense (or benefit) from continuing operations, to (2) the product of the income (or loss) from continuing operations before income taxes and the applicable statutory federal (national) income tax rate of the jurisdiction (country) of domicile using specific categories, and separate disclosure for any reconciling items within certain categories that are equal to or greater than a specified quantitative threshold. For each annual period presented, ASU 2023-09 also requires all reporting entities to disclose the year-to-date amount of income taxes paid (net of refunds received) disaggregated by federal (national), state, and foreign. It also requires additional disaggregated information on income taxes paid (net of refunds received) to an individual jurisdiction equal to or greater than 5% of total income taxes paid (net of refunds received). ASU 2023-09 is effective for public entities for fiscal years beginning after December 15, 2024. ASU 2023-09 is to be applied on a prospective basis with the option to apply the standard retrospectively. Early adoption is permitted. The Company will adopt this standard and disclose any impact from this standard in its fiscal year 2026 consolidated financial statements. In November 2024, the FASB issued ASU 2024-03, “Income Statement-Reporting Comprehensive Income-Expense Disaggregation Disclosures (Subtopic 220-40) - Disaggregation of Income Statement Expenses” (“ASU 2024-03”), which requires additional disclosure about specified categories of expenses included in relevant expense captions presented on the income statement. The amendments are effective for annual periods beginning after December 15, 2026, and for interim periods within fiscal years beginning after December 15, 2027. Early adoption is permitted. The amendments may be applied either prospectively or retrospectively. The Company is currently evaluating the impact that ASU 2024-03 will have on its disclosures. The Company considers the applicability and impact of all ASUs issued by the FASB. There are no other accounting pronouncements which have been issued but are not yet effective that would have a material impact on the consolidated financial statements when adopted.

Equity [Abstract]
Equity	Equity 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”). 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 112,635,932 shares were issued and outstanding on September 27, 2025. 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 of September 27, 2025 there were 74,693,311 shares of Class V-1 and 403,559,196 shares of Class V-3 Common Stock outstanding. For the year ended September 27, 2025, the Legacy Warehouse unitholders exchanged 2,075,174 and 750,000 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 27, 2025.

Cybersecurity Risk Management, Strategy, and Governance [Line Items]
Cybersecurity Risk Management Processes for Assessing, Identifying, and Managing Threats [Text Block]	Our cybersecurity programs and procedures are designed to identify and address threats that are subject to ongoing compliance assessments, certifications, and testing. We conduct assessments of threat models to determine which risks are most likely to impact us. Our security and controls team gathers threat and risk data and updates through various sources, such as systems reviews, security research activities, and internal and external security scans and alerts, as appropriate. As applicable, in certain circumstances, we also collaborate with industry partners in the security community, our peers and law enforcement agencies, to support our cybersecurity threat intelligence capabilities. This information is collected, categorized, and assessed to identify, prioritize, and manage significant cybersecurity risks. As a result, our process is continually evaluated and evolves as the threat landscape changes. We have also incorporated security practices into employee trainings. We have a process for employees to formally acknowledge their review and understanding of security obligations. Additionally, our security and controls team conducts periodic security and data protection training aimed to emphasize the importance of security and data protection. We have also implemented a review process to assess the security profile and data protection practices of certain third-party suppliers and service providers that have exposure to our systems, including, as appropriate, review of vendor security policies and procedures. We do not, however, review security profile and data protection practices of all third-party vendors. In the event of a cybersecurity incident, our response and mitigation efforts are guided by the Incident Response Plan (“IRP”), which provides guidance on how to respond to, and recover from, a material cyber incident requiring an organized response. We conduct tabletop exercises testing the principles and procedures set forth in our IRP based on lessons learned. In addition, we have a cybersecurity disclosure committee (“Cybersecurity Disclosure Committee”) which receives updates on an as needed basis from our security organization regarding cybersecurity incidents. The Cybersecurity Disclosure Committee includes our CIO and senior representatives from finance, controllership, internal audit, investor relations, and legal teams. In the event of a cybersecurity incident, the Cybersecurity Disclosure Committee meets to assess the incident for materiality and required disclosure. While we have experienced a cybersecurity incident in the past, as of the date hereof, none have materially affected us or our business strategy, financial condition, results of operations, and/or cash flows. We continue to invest in cybersecurity and resiliency of our networks to enhance our internal controls and processes, which are designed to help protect our systems and infrastructure, and the information which they contain. For more information about cybersecurity risks relating to our business, refer to Item 1A, Risk Factors included in this Annual Report on Form 10-K.

Related parties are generally defined as (i) affiliates of the Company; (ii) owners of more than 10% of the voting interests of the Company and members of their immediate families; (iii) management of the Company and members of their immediate families; (iv) other parties which directly or indirectly control, are controlled by, or are under common control with the Company; or (v) other parties who can significantly influence the financial and operating decisions of the Company. A transaction is considered to be a related party transaction when there is a transfer of resources or obligations between related parties. The Company assesses related parties each reporting period. For the reporting periods covered by this report, the Company determined that C&S Wholesale Grocers, Inc. (“C&S”), GreenBox, and certain current holders of Symbotic Holdings were each a related party under ASC Topic 850. The following transactions were related party transactions under ASC Topic 850.

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 $1.3 million, $1.1 million, and $0.9 million related to these aircraft time-sharing agreements for the years ended September 27, 2025, September 28, 2024, and September 30, 2023, respectively.

Goodwill and Intangible Assets Disclosure [Abstract]

Intangible Assets and Goodwill

In connection with asset acquisitions in fiscal year 2024 and 2025, and the ASR Acquisition in January 2025, the Company acquired developed technology intangible assets. The intangible assets acquired will be amortized over a useful life of 3 to 7 years on a straight-line basis. The estimated weighted average useful life of the intangible assets is 6.5 years.

Acquired intangible assets that are subject to amortization consisted of the following as of September 27, 2025 and September 28, 2024 (in thousands):

Commitments and Contingencies Disclosure [Abstract]

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 $893.9 million as of September 27, 2025.

Lease Commitments

The Company leases certain of its facilities under operating leases expiring in various years through 2030. Refer to Note 5, Leases for a schedule of future lease payments under non-cancellable leases as of September 27, 2025.

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 27, 2025		September 28, 2024		September 30, 2023

Warranty usage	(11,384)		(5,786)		(6,889)
Balance at end of period	$	43,607	$	31,935	$	18,948

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 other 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.

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. On March 10, 2025, the plaintiff voluntarily dismissed this action without prejudice pursuant to Federal Rule of Civil Procedure 41(a)(1)(A)(i). 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 asserted 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 brought 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. On May 5, 2025, the court entered an order appointing a lead plaintiff pursuant to the Private Securities Litigation Reform Act and setting a schedule for the filing of an amended complaint and the Company’s response to the complaint.

On July 11, 2025, plaintiffs filed an amended complaint captioned Traina v. Symbotic Inc. et al., Case No. 24-cv-12196. Like the Decker complaint, the amended complaint asserts claims for violations of federal securities laws against the Company and four of officers of the Company on the grounds that the Company made false and/or misleading statements or omissions related to its financial results, deployment times, revenue recognition, and internal controls. Based on these allegations, the plaintiffs bring claims seeking unspecified damages, attorneys’ fees, expert fees, and other costs and relief on behalf of themselves and a putative class of persons who purchased stock of the Company between November 20, 2023 and February 5, 2025.

The Company filed a motion to dismiss the amended complaint on September 11, 2025. The plaintiffs filed an opposition to the motion to dismiss on November 11, 2025. The Company’s reply brief in support of its motion to dismiss is due on December 11, 2025. A hearing on the motion to dismiss is scheduled for December 16, 2025.

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. We 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. Motions 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 securities class action lawsuit remain pending.

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 27, 2025, 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.

Indemnifications

In the ordinary course of business, the Company enters into various contracts under which it may agree to indemnify other parties for losses incurred from certain events as defined in the relevant contract, such as litigation, regulatory penalties, or claims relating to past performance. Such indemnification obligations may not be subject to maximum loss clauses. The Company has never incurred costs to defend lawsuits or settle claims related to these indemnification obligations. As a result, the Company believes the estimated fair value of these obligations is not material. Accordingly, the Company has no liabilities recorded for these obligations as of September 27, 2025 and September 28, 2024.

As a result of the Business Combination, the Company was appointed as the sole managing member of Symbotic Holdings. 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. In the United States, the valuation allowance is predominantly related to the Company’s investment in Symbotic Holdings LLC, while the foreign valuation allowance is related to Canada.

Due to the acquisition of ASR during the year ended September 27, 2025, the Company recorded additional deferred tax assets in the United States with an offsetting increase to the valuation allowance. As part of the acquisition accounting, a portion of the valuation allowance increase was determined to relate to goodwill. In addition, as part of the acquisition accounting, deferred tax liabilities provided a source of future taxable income enabling the release of a small portion of the valuation allowance. As a result, the Company’s ending valuation allowance as of the year ended September 27, 2025 is $627.9 million and consists of $618.4 million in the United States and $9.5 million in foreign jurisdictions. The change in the valuation allowance in fiscal year 2025 of $81.8 million predominantly relates to the Company’s investment in Symbotic Holdings LLC, tax carryforward attributes, and the Company’s acquisition of ASR.

Activity related to the valuation allowance for the periods presented was as follows (in thousands):


	Year Ended
	September 27, 2025		September 28, 2024		September 30, 2023
Beginning balance	$	546,090	$	370,996	$	134,246
Recorded to additional paid-in capital	56,420		180,412		233,563
Recorded to goodwill	44,825		—		—
Recorded to income tax expense	(19,467)		(5,318)		3,187
Ending balance	$	627,868	$	546,090	$	370,996

Net Operating Losses

As of September 27, 2025, the Company had U.S. federal net operating loss (“NOL”) carryforwards of $315.4 million and gross state NOL carryforwards of $220.7 million. U.S. federal and certain state NOLs generated in 2018 and beyond have no expiration. The remaining state NOLs expire at various dates through 2043. As of September 27, 2025, the Company had Canadian NOL carryforwards of approximately $24.4 million. The Canadian NOL carryforwards expire in various years

through 2037 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 27, 2025, 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 27, 2025 and September 28, 2024, the Company had no unrecognized tax benefits.

Tax Receivable Agreement

As of September 27, 2025, future payments under the TRA with respect to the purchase of Symbotic Holdings Units which occurred as part of the Business Combination and through September 27, 2025 are projected to be $452.9 million, and if paid, would create additional tax basis in the partnership. Payments made under the TRA represent payments that otherwise would have been made to taxing authorities in the absence of attributes obtained by the Company as a result of exchanges by its pre-IPO members. Such amounts will be paid only when a cash tax savings is realized as a result of attributes subject to the TRA. That is, payments under the TRA are only expected to be made in periods following the filing of a tax return in which the Company is able to utilize certain tax benefits to reduce its cash taxes paid to a taxing authority. The impact of any changes in the projected obligations under the TRA as a result of changes in the geographic mix of the Company’s earnings, changes in tax legislation and tax rates or other factors that may impact the Company’s tax savings will be reflected in income before taxes on the consolidated statement of operations in the period in which the change occurs. As of September 27, 2025, no TRA liability was recorded based on current projections of future taxable income taking into consideration the Company’s full valuation allowance against its net U.S. deferred tax asset.

The fair value of the ESPP is estimated using the Black-Scholes option-pricing model with the following assumptions:


	Year Ended
	September 27, 2025	September 28, 2024
Risk-free interest rate (%)	0.04 - 0.05	0.05

Volatility (%)	54.67 - 73.27	63.54 - 73.27
Expected dividends	—	—

Schedule of Warrants, Valuation Assumptions

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

Variable Interest Entities

12 Months Ended

Sep. 27, 2025

Organization, Consolidation and Presentation of Financial Statements [Abstract]

Variable Interest Entities

VIEs are entities with any of the following characteristics: (i) the entity does not have enough equity to finance its activities without additional financial support; (ii) the equity holders, as a group, lack the characteristics of a controlling financial interest; or (iii) the entity is structured with non-substantive voting rights.

Consolidation of a VIE is required for the party deemed to be the primary beneficiary, if any. The primary beneficiary is the party who has both (a) the power to direct the activities of a VIE that most significantly impact the entity’s economic performance and (b) an obligation to absorb losses of the entity or a right to receive benefits from the entity that could potentially be significant to the entity.

On July 23, 2023, the Company, New Symbotic Holdings, and Symbotic LLC (collectively, the “Symbotic Group”), entered into a Framework Agreement (the “Framework Agreement”) with Sunlight Investment Corp., a Delaware corporation (“Sunlight”), SVF II Strategic Investments AIV LLC, a Delaware limited liability company (“SVF” and, together with Sunlight, “SoftBank”), and GreenBox, related to, among other things, the formation of GreenBox as a venture between the Symbotic Group and SoftBank and a warrant to purchase Class A Common Stock of Symbotic (the “GreenBox Warrant”). On July 23, 2023, GreenBox also entered into a Master Services, License and Equipment Agreement with Symbotic LLC with respect to the purchase of Systems (“GreenBox Commercial Agreement”).

GreenBox was established on July 21, 2023 to build and automate supply chain networks globally by operating and financing the Company’s artificial intelligence and automation technology for the warehouse. Symbotic Holdings and Sunlight own 35% and 65% of GreenBox, respectively. The Company evaluated for VIEs upon the formation of GreenBox in accordance with ASC Topic 810, Consolidation. The Company holds a variable interest in GreenBox through its equity interest in GreenBox. 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 27, 2025
	Investments in Unconsolidated VIE		Symbotic's Maximum Exposure to Loss
GreenBox Systems LLC	$	123,034	$	1,574,240

The Company calculated its maximum exposure to loss of $1,574.2 million 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 $1,561.1 million. As of September 27, 2025, there is a $123.0 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 GreenBox Commercial Agreement to reimburse the Company in the event of a termination. If the VIE’s commitment under the GreenBox Commercial Agreement was taken into consideration, there would be no maximum exposure to loss presented as the VIE’s commitment under the GreenBox Commercial Agreement exceeds the Company’s future funding commitments.

Segment Reporting [Abstract]

Segment and Geographic Information

As more fully described in the Company’s Summary of Significant Accounting Policies, 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 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. There is no expense or asset information, that are supplemental to those disclosed in these consolidated financial statements, that are regularly provided to the CODM. The allocation of resources and assessment of performance of the operating segment is based on consolidated net loss and gross margin as shown in our consolidated statements of operations. The CODM considers net loss and gross margin in the annual forecasting process and reviews actual results when making decisions about allocating resources. Since the Company operates as one operating segment, financial segment information, including profit or loss and asset information, can be found in the consolidated financial statements.

Geographic Information

Revenue and property and equipment, net by geographic region, based on physical location of the operations recording the sale or the assets are as follows:

Revenue from Contract with Customer [Abstract]

Revenue

Disaggregation of Revenue

The Company provides disaggregation of revenue based on product and service type on the consolidated statements of operations as it believes these categories best depict how the nature, amount, timing, and uncertainty of revenue and cash flows are affected by economic factors.

Contract Balances

The following table provides information about accounts receivable, unbilled accounts receivable, and contract liabilities from contracts with customers (in thousands):


	September 27, 2025		September 28, 2024
Accounts receivable	$	186,705	$	201,548
Unbilled accounts receivable	$	181,658	$	218,233
Contract liabilities	$	1,367,244	$	805,547

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 unbilled accounts receivable and 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. When satisfaction of the performance obligations occurs in advance of invoicing or payment being received, an unbilled accounts receivable is generated. For the year ended September 30, 2023, the ending balance of accounts receivable, unbilled accounts receivable, and contract liabilities was $69.2 million, $121.1 million, and $787.2 million, respectively. During the years ended September 27, 2025 and September 28, 2024, the Company recognized $737.2 million and $723.2 million, respectively, of the contract liability balance at the beginning of the period as revenue upon transfer of the products or services to customers.

2025 Walmart Master Automation Agreement

In the second quarter of fiscal year 2025, Symbotic LLC entered into a Master Automation Agreement (“2025 Walmart MAA”), which sets forth the terms and conditions governing the development, manufacture, and installation of accelerated pickup and delivery systems (“APDs”) by Symbotic LLC for Walmart. The 2025 Walmart MAA provides for a commitment, contingent upon the satisfaction of defined system performance metrics of the APDs, from Walmart to purchase 400 APDs. The Company determined that the contingent promise to acquire additional goods and services in the future conveys a material right to Walmart. Estimating the standalone selling price of the performance obligations under the 2025 Walmart MAA and estimating the goods and services expected to be provided and their corresponding expected transaction price if Walmart exercises the material right conveyed by the 2025 Walmart MAA involved significant judgment.

Remaining Performance Obligations

Remaining performance obligations represent the aggregate amount of the transaction price allocated to performance obligations not delivered, or partially undelivered, at the end of the reporting period. Remaining performance obligations include deferred revenue plus unbilled amounts not yet recorded in deferred revenue. Remaining performance obligation estimates are subject to change and are affected by several factors, including terminations, changes in scope of contracts, periodic revalidation, adjustments for revenue that have not materialized, adjustments for inflation, and adjustments for currency. The definition of remaining performance obligations excludes those contracts that provide the customer with the right to cancel or terminate the contract without incurring a substantial penalty. For contracts with a duration of greater than one year, the transaction price allocated to performance obligations that are unsatisfied as of September 27, 2025 was $22.5 billion, which is primarily comprised of undelivered or partially undelivered Systems under contract, and which a substantial majority relates to undelivered or partially undelivered Systems in connection with the Master Automation Agreement (“MAA”) with Walmart Inc. (“Walmart”) to implement Systems in all of Walmart’s 42 regional distribution centers, and in connection with the Commercial Agreement with GreenBox Systems LLC (“GreenBox”) under which Symbotic will implement its System into GreenBox distribution center locations. As the Company accounts for GreenBox as an equity method investment, the remaining performance obligation includes the Company’s proportionate share of unconsolidated variable interest entity contracts. In addition, the contingent promise to purchase 400 APDs under the 2025 Walmart MAA could increase the Company’s future remaining performance obligation by more than $5.0 billion. The Company expects to recognize approximately 12% of its remaining performance obligations as revenue in the next 12 months, approximately 62% of its remaining performance obligations as revenue within the following 13 to 60 months, and the remaining thereafter, which is dependent on the timing of System installation timelines. The Company does not disclose the value of remaining performance obligations for contracts with an original expected duration of one year or less or for performance obligations where revenue is recognized under the right to invoice practical expedient.

- Definition

The entire disclosure of revenue from contract with customer to transfer good or service and to transfer nonfinancial asset. Includes, but is not limited to, disaggregation of revenue, credit loss recognized from contract with customer, judgment and change in judgment related to contract with customer, and asset recognized from cost incurred to obtain or fulfill contract with customer. Excludes insurance and lease contracts.

Restructuring Charges

Sep. 27, 2025

Restructuring and Related Activities [Abstract]

Restructuring Charges

During the third quarter of fiscal year 2025, management committed to a reduction of the Company’s workforce by approximately 325 employees primarily related to employees that joined the Company’s workforce in connection with the ASR Acquisition. The Company expects the workforce reduction will be substantially completed by the end of the first quarter of fiscal year 2026. The costs incurred related to employee severance are recorded as a liability when it is probable that employees will be entitled to termination benefits and the amounts can be reasonably estimated. The liability related to these charges is included in accrued expenses and other current liabilities in the Company’s consolidated balance sheets. As the ASR Purchase Agreement contemplated reimbursement for certain types of restructuring costs, a receivable was recorded, which is included outside of the purchase price allocation for the business combination as indicated in Note 8, Business Acquisitions. The Company did not have any material severance activity for the period ended September 28, 2024.

The following table presents the activity related to the Company’s severance liability as of September 27, 2025 (in thousands).

Net Loss per Share

12 Months Ended

Sep. 27, 2025

Earnings Per Share [Abstract]

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.


	Year Ended
	September 27, 2025		September 28, 2024		September 30, 2023
Numerator - basic and diluted
Net loss	$	(91,032)	$	(84,672)	$	(207,894)
Less: Net loss attributable to the noncontrolling interest	(74,095)		(71,182)		(184,028)
Net loss attributable to common shareholders	$	(16,937)	$	(13,490)	$	(23,866)
Denominator - basic and diluted
Weighted-average shares of Class A Common Stock outstanding	108,670,159		95,697,368		64,338,580
Loss per share of Class A Common Stock - basic and diluted	$	(0.16)	$	(0.14)	$	(0.37)

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”), shares issued under the 2022 Employee Stock Purchase Plan (“ESPP”), and Warrant Units (defined below). The average stock price for the year ended September 27, 2025 was $32.64. For the year ended September 27, 2025, there were 8.4 million potentially dilutive common stock equivalents related to the RSUs. For the year ended September 27, 2025, there were 3.3 million anti-dilutive common stock equivalents related to the unvested GreenBox Warrant, which could potentially dilute EPS in the future.

The average stock price for the year ended September 28, 2024 was $38.79. For the year ended September 28, 2024, there were 5.6 million potentially dilutive common stock equivalents related to the RSUs. For the year ended September 28, 2024, there were 1.0 million anti-dilutive common stock equivalents related to the unvested GreenBox Warrant, which could potentially dilute EPS in the future.

The average stock price for the year ended September 30, 2023 was $25.30. For the year ended September 30, 2023, there were 7.6 million and 9.6 million potentially dilutive common stock equivalents related to the RSUs and Warrant Units.

Business Acquisitions

Business acquisition-related costs were $7.5 million during the year ended September 27, 2025, and are included in general and administrative expenses in the consolidated statements of operations. Separate financial results and pro forma financial information for ASR (defined below) have not been presented as the effect of this acquisition was not material to the Company’s financial results.

Advanced Systems & Robotics Inc.

On January 27, 2025, the Company acquired all of the outstanding equity interests of Walmart’s Advanced Systems & Robotics Inc. (“ASR”) for $200.0 million in cash (the “ASR Acquisition) pursuant to a Purchase and Sale Agreement with Walmart (the “ASR Purchase Agreement”). Included in the $200.0 million payment is a $45.0 million payment to Walmart as the Company’s customer under the 2025 Walmart MAA. The allocation of the $200.0 million payment made to Walmart between the acquisition of ASR and the concurrent revenue arrangement involved judgment in (1) assessing whether the concurrent revenue and other arrangement represent transactions that are separate from the acquisition of ASR, and (2) estimating the fair value of the ASR business, which is used to adjust contractually stated amounts to reflect an amount that would be paid to acquire ASR without a concurrent revenue arrangement. This payment is accounted for as a reduction of the transaction price and is offset against the short-term deferred revenue on the consolidated balance sheets. Also included in the $200.0 million payment is an employee cost reimbursement asset of $13.2 million, which relates to certain restructuring costs

reimbursed to the Company by Walmart in the fourth quarter of fiscal year 2025, and thus does not appear in the consolidated balance sheets at September 27, 2025. The ASR Purchase Agreement is intended to expand the long-standing relationship between Walmart and the Company with the aim of developing an integrated automated supply chain, which is expected to broaden the Company’s product offering beyond the traditional warehouse to eCommerce settings for last mile delivery. As of September 27, 2025, the purchase price allocation is preliminary, pending finalization of valuations and the impact of income taxes.

The preliminary allocation of the purchase price for ASR and fair values of the assets acquired and liabilities assumed were as follows (in thousands):


Total purchase price	$	200,000
Consideration payable to customer	(45,000)
Employee cost reimbursement asset	(13,169)
Purchase price - business combination	$	141,831

Allocation of purchase price - business combination
Inventories	$	13,749
Prepaid expenses and other current assets	24,634
Property and equipment, net	4,261
Intangible assets	78,000
Other assets	2,223
Total assets acquired	122,867
Accrued expenses and other current liabilities	38,296
Other liabilities	2,611
Total liabilities assumed	40,907
Identifiable net assets acquired	81,960
Goodwill	59,871
Total purchase price allocation	$	141,831

The value of the goodwill can be attributed to a number of business factors, including a trained technical workforce, and revenue and cost synergies expected to be realized. The Company expects that most of the goodwill related to the ASR Acquisition will not be deductible for tax purposes.

The identified intangible asset acquired is developed technology, which has a gross carrying amount of $78.0 million and has an estimated useful life of 7 years.

The Company applied the multi-period excess earnings method to estimate the fair value of the intangible asset. The total weighted average amortization period for the developed technology intangible asset acquired from Walmart is 7 years. The intangible asset began amortization on the date of acquisition and is amortized on a straight-line basis over its useful life.

Accounting Policies [Abstract]

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 years ended September 27, 2025, September 28, 2024 and September 30, 2023, 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 27, 2025 was a 52-week period, the fiscal year ended September 28, 2024 was a 52-week period, and the fiscal year ended September 30, 2023 was a 53-week period.

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, valuation of business and identifiable net assets acquired, valuation of investments, 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.

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.

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.

Strategic Investments

Strategic investments consist of non-marketable equity investments of privately held companies in which the Company does not have a controlling interest.

The Company may elect to apply the measurement alternative or the fair value option for investments without readily determinable fair values for which the Company does not have the ability to exercise significant influence. Under the measurement alternative, the non-marketable securities are carried at cost less any impairments, plus or minus adjustments resulting from observable price changes in orderly transactions for identical or similar investments of the same issuer. On a quarterly basis, the Company performs a qualitative assessment to evaluate whether the investment is impaired. If there are sufficient indicators that the fair value of the investment is less than the carrying value, the carrying value of the investment is reduced and an impairment is recorded in the consolidated statements of operations in other income (expense).

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. The Company had no current expected credit losses at September 27, 2025 and September 28, 2024.

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 27, 2025, 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 27, 2025, September 28, 2024, and September 30, 2023, 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 27, 2025		September 28, 2024		September 30, 2023
Customer A	84.6	%	86.9	%	88.4	%

At September 27, 2025 and September 28, 2024, one customer accounted for over 10% of the Company’s accounts receivable balance. The following table represents this customer’s aggregate percent of total accounts receivable.


	September 27, 2025		September 28, 2024
Customer A	75.8	%	92.8	%

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 27, 2025, there was one supplier that accounted for greater than 10% of total purchases, and the aggregate purchases from that supplier amounted to $198.9 million. 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 these suppliers amounted to $343.0 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 weighted average 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, test equipment, and other equipment			3 - 7 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, costs are capitalized to prepaid expenses and other current assets on the Company’s consolidated balance sheets.

Business Acquisitions

The Company allocates the fair value of purchase consideration to the tangible assets acquired, liabilities assumed, and intangible assets acquired based on their estimated fair values. The excess of the fair value of purchase consideration over the fair value of these identifiable assets and liabilities is recorded as goodwill. During the measurement period, which may be up to one year from the acquisition date, the Company may record adjustments to the fair value of these assets acquired and liabilities assumed with the corresponding offset to goodwill. Upon the conclusion of the final determination of the fair value of assets acquired or liabilities assumed, any subsequent adjustments are recorded to the consolidated statements of operations. Determining the fair value of the tangible assets acquired, liabilities assumed, and intangible assets requires management to make significant estimates and assumptions, especially with respect to intangible assets. Significant estimates in valuing certain intangible assets include, but are not limited to, cash flows that an asset is expected to generate in the future, technology migration curves, discount rates, and useful lives. While the Company uses its best estimates and judgments, the estimates are inherently uncertain and subject to refinement. Acquisition-related transaction costs are expensed as incurred.

Acquired Intangible Assets and Long-Lived Assets

Acquired intangible assets consist of developed technology. 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. For the years ended September 27, 2025 and September 30, 2023, the Company recognized impairment losses of $2.7 million and $0.1 million, respectively. No impairment losses were recognized for the year ended September 28, 2024.

Goodwill

Goodwill represents the excess of cost over the fair value of the net tangible and identifiable intangible assets acquired in a business combination. Goodwill is not subject to amortization but is monitored annually for impairment or more frequently if there are indicators of impairment. The Company considers the following potential indicators of impairment: significant underperformance relative to historical or projected future operating results, significant changes in the Company’s use of acquired assets or the strategy of the Company’s overall business, significant negative industry or economic trends and a significant decline in the Company’s stock price for a sustained period. The Company performs its annual impairment test on the first day of its fourth fiscal quarter. The Company’s goodwill is evaluated at the consolidated level as it has been determined there is one operating segment comprised of one reporting unit. The Company performs a quantitative or qualitative assessment, which compares the fair value of the reporting unit with its carrying value. If the carrying amount of the reporting unit exceeds its fair value, an impairment loss is recognized. Based on the qualitative assessment performed on the first day of the fourth fiscal quarter, or June 29, 2025, no indicators of impairment existed, and as such, there was no impairment of goodwill as of June 29, 2025. There were no triggering events after the measurement date that may indicate impairment as of September 27, 2025. The Company did not carry a goodwill balance for the years ended September 28, 2024 and 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 incremental borrowing rate is derived from information available at the lease commencement date. To determine the estimated incremental borrowing rate, the Company uses publicly available credit ratings for peer companies. The Company estimates the incremental borrowing rate using yields for maturities that are in line with the duration of the lease payments.

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 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 and training services to customers as needed to service their System.

The Company recognizes revenue as control of promised goods or services in a contract is transferred to the customer, in an amount that reflects the consideration the Company expects to receive in exchange for those products or services. The Company considers the contractual consideration payable by the customer and assesses variable consideration that may affect the total transaction price, including contractual discounts, changes in total System contract cost estimates, contract incentive payments, shipping fees, inflation adjustments, and other sources of variable consideration, when determining the transaction price of each contract. The Company accounts for all consideration payable to a customer as a reduction of revenue. Consideration payable to a customer may include cash amounts that the Company is obligated to pay or expects to pay a customer, as well as credits or other items that can be applied against amounts owed to the Company from the customer. Variable consideration 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.

Certain contracts may provide the customer with a material right through a contingent promise or an option to acquire additional goods and services in the future. The Company accounts for the material right as a separate performance obligation

where a portion of the transaction price is allocated based on the expected goods and services and the expected consideration if a customer exercises that material right. The transaction price allocated to the material right is then recognized as revenue over the period in which control over the goods and services underlying the material right is transferred to the customer. The Company identified a material right obligation in connection with the 2025 Walmart MAA to develop and produce APDs (further defined in Note 4, Revenue).

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.

As customer acceptance can be reasonably certain upon contract inception, the Company recognizes revenue over time based on an input method. 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 Company has elected the right to invoice practical expedient for operation services where we are assisting customers with operating their System. Accordingly, the Company recognizes revenue based on actual costs incurred. Sales of spare parts and training services are recognized at a point in time upon transfer of title of the spare parts or occurrence of training services, respectively. Certain of the Company’s contracts contain variable consideration where additional amounts can be earned based on specified contract criteria. These amounts are included in the transaction price to the extent it is not probable there will be a significant reversal of revenue.

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 the contract 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 material contract losses recorded in the consolidated statements of operations for the fiscal years ended September 27, 2025, September 28, 2024, and September 30, 2023. There were no material anticipated contract losses recorded in accrued expenses on the consolidated balance sheets as of September 27, 2025 and September 28, 2024.

The Company’s 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

On July 23, 2023, the Company, New Symbotic Holdings, and Symbotic US (collectively, the “Symbotic Group”), entered into a Framework Agreement (the “Framework Agreement”) with Sunlight Investment Corp., a Delaware corporation (“Sunlight”), SVF II Strategic Investments AIV LLC, a Delaware limited liability company (“SVF” and, together with Sunlight, “SoftBank”), and GreenBox Systems LLC, a Delaware limited liability company (“GreenBox”), related to the formation of GreenBox as a strategic joint venture between the Symbotic Group and SoftBank, the entry into a Limited Liability Company Agreement of GreenBox and Master Services, License and Equipment Agreement and the issuance of a warrant to purchase Class A Common Stock of Symbotic (the “GreenBox Warrant”). The GreenBox Warrant issues SoftBank warrants to acquire up to an aggregate of 11,434,360 shares of Symbotic Class A common stock, subject to certain vesting conditions as GreenBox makes expenditures of the Company’s warehouse automation system under the Framework Agreement. Upon vesting, shares may be acquired at an exercise price of $41.9719. The right to purchase shares in connection with the GreenBox Warrant expires on July 23, 2032.

On April 30, 2021, the Company and Walmart Inc. (“Walmart”) entered into a Subscription Agreement (the “Subscription Agreement”), in which the Company issued to Walmart warrants to acquire up to an aggregate of 714,022 shares of the Legacy Warehouse Class A Units (the “Warrants” and the Class A Units issuable thereunder, the “Warrant Units”), subject to certain vesting conditions. Warrants equivalent to 6.5% of the Company’s then outstanding and issuable Common Units, or 446,741 units, vested upon the signing of the Subscription Agreement. Warrants equivalent to up to 3.5% of the Company’s then outstanding and issuable Common Units, or 267,281 units, were subject to vest in connection with conditions defined by the terms of the Warrant, as Walmart made additional expenditures to the Company in connection with the Subscription Agreement, and vested on May 20, 2022. Upon vesting, units were acquired at an exercise price of $389.03. The right to purchase units in connection with the Subscription Agreement expires on April 30, 2031. On May 20, 2022, the Company and Walmart entered into the 2nd Amended and Restated Master Automation Agreement (“2nd A&R MAA”), in which the Company issued to 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. In connection with the closing of the Business Combination, 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”). Warrant Units equivalent to up to 3.6% of the Company’s then outstanding and issuable Common Units, or 15,870,411 units, may vest in connection with conditions defined by the terms of the June 2022 Warrant. Upon vesting, units may be acquired at an exercise price of $10.00. The right to purchase units in connection with the June 2022 Warrant expires on June 7, 2027. 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.

The warrant units granted to Walmart and the GreenBox Warrant are accounted for as equity instruments and measured in accordance with ASC Topic 718, Compensation—Stock Compensation. These instruments are classified in the consolidated statements of operations in accordance with ASC Topic 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 Topic 606. To determine the fair value of the warrants in accordance with ASC Topic 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 11, Income Taxes, for further details.

The Company accounts for income taxes in accordance with ASC Topic 740, Accounting for Income Taxes, 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.

Recent Accounting Pronouncements

In November 2023, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2023-07, “Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures” (“ASU 2023-07”), which requires enhanced disclosures about significant segment expenses and introduces a reconciliation between segment revenue and segment profitability metrics. As required, the Company has adopted the standard in the current fiscal year and incorporated all expanded disclosure requirements in Note 21, Segment and Geographic Information.

In December 2023, the FASB issued ASU 2023-09, “Income Taxes (Topic 740): Improvements to Income Tax Disclosures” (“ASU 2023-09”). ASU 2023-09 requires public entities, on an annual basis, to provide: a tabular rate reconciliation (using both percentages and reporting currency amounts) of (1) the reported income tax expense (or benefit) from continuing operations, to (2) the product of the income (or loss) from continuing operations before income taxes and the applicable statutory federal (national) income tax rate of the jurisdiction (country) of domicile using specific categories, and separate disclosure for any reconciling items within certain categories that are equal to or greater than a specified quantitative threshold. For each annual period presented, ASU 2023-09 also requires all reporting entities to disclose the year-to-date amount of income taxes paid (net of refunds received) disaggregated by federal (national), state, and foreign. It also requires additional disaggregated information on income taxes paid (net of refunds received) to an individual jurisdiction equal to or greater than 5% of total income taxes paid (net of refunds received). ASU 2023-09 is effective for public entities for fiscal years beginning after December 15, 2024. ASU 2023-09 is to be applied on a prospective basis with the option to apply the standard retrospectively. Early adoption is permitted. The Company will adopt this standard and disclose any impact from this standard in its fiscal year 2026 consolidated financial statements.

In November 2024, the FASB issued ASU 2024-03, “Income Statement-Reporting Comprehensive Income-Expense Disaggregation Disclosures (Subtopic 220-40) - Disaggregation of Income Statement Expenses” (“ASU 2024-03”), which requires additional disclosure about specified categories of expenses included in relevant expense captions presented on the income statement. The amendments are effective for annual periods beginning after December 15, 2026, and for interim periods within fiscal years beginning after December 15, 2027. Early adoption is permitted. The amendments may be applied either prospectively or retrospectively. The Company is currently evaluating the impact that ASU 2024-03 will have on its disclosures.

The Company considers the applicability and impact of all ASUs issued by the FASB. There are no other accounting pronouncements which have been issued but are not yet effective that would have a material impact on the consolidated financial statements when adopted.

Recent Legislation

On July 4, 2025, the One Big Beautiful Bill Act (“OBBBA”) was signed into law in the United States. Key provisions of the OBBBA include permanent extension of once-temporary provisions of the Tax Cuts and Jobs Act of 2017, along with the introduction of other significant changes that may impact the Company. The legislation has multiple effective dates, with certain provisions effective in the Company’s fiscal year 2025 and others implemented through the Company’s fiscal year 2028. The Company continues to evaluate the impact of the OBBBA and has included the impact of changes in the law that were effective during its fiscal year 2025 in the results of its consolidated financial statements.

Share-Based Payment Arrangement [Abstract]

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 80,811,586 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 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.

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 30, 2023	12,884,015	$	15.81

The total fair value of RSUs that vested during the years ended September 27, 2025, September 28, 2024 and September 30, 2023 was $154.5 million, $295.5 million, and $90.7 million, respectively. For the years ended September 27, 2025, September 28, 2024, and September 30, 2023, the weighted-average fair value of RSU awards granted was $32.73, $44.44, and $15.72 per share, respectively. As of September 27, 2025, 12.8 million RSUs were outstanding and unvested, with an aggregate value of $665.9 million and a weighted average remaining vesting period of approximately 1.10 years. These RSUs are expected to vest on various dates through 2028.

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 3,767,734 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.

The fair value of the ESPP is estimated using the Black-Scholes option-pricing model with the following assumptions:


	Year Ended
	September 27, 2025	September 28, 2024
Risk-free interest rate (%)	0.04 - 0.05	0.05
Expected term (years)	0.50	0.50
Volatility (%)	54.67 - 73.27	63.54 - 73.27
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 27, 2025, 364,855 shares of common stock were issued to employees who participated in the plan with a weighted average purchase price of $17.00 per share for total cash proceeds of $6.2 million, net of taxes. 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.

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 27, 2025, 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

(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 Topic 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

(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

(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.

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 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”). 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, commercializing, and deploying innovative and comprehensive technology solutions that dramatically improve supply chain operations. The Company automates the processing of pallets, cases and individual items in warehouses. 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.

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 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 Topic 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. The fair value of the warrants recognized within “other assets” on the Company’s condensed consolidated balance sheets at September 27, 2025 is $16.8 million. The Company recorded a fair value adjustment of $4.5 million to “other income, net” on the Company’s condensed consolidated statements of operations for the year ended September 27, 2025. There was no fair value adjustment recorded for the year ended September 28, 2024, as there had been no change to the fair value of the warrants for the year ended September 28, 2024.

Fair Value Measures

Fair Value Disclosures [Abstract]

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


	Year Ended
	September 27, 2025								September 28, 2024
	Level 1		Level 2		Level 3		Total		Level 1		Level 2		Level 3		Total
Assets:
Money market funds	$	1,193,375	$	—	$	—	$	1,193,375	$	712,958	$	—	$	—	$	712,958
Warrant fair value	—		16,789		—		16,789		—		12,308		—		12,308
Strategic investments	—		—		43,334		43,334		—		—		—		—
Total assets	$	1,193,375	$	16,789	$	43,334	$	1,253,498	$	712,958	$	12,308	$	—	$	725,266

The Company had no liabilities measured and recorded at fair value on a recurring basis as of September 27, 2025 and September 28, 2024.

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 27, 2025 and September 28, 2024, the fair value of the warrant issued as described in Note 14, Derivative Instruments, is classified as Level 2 and was 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. Certain non-marketable strategic investments measured at fair value on a non-recurring basis are classified as Level 3 as their fair value measurements may include a combination of observable and unobservable inputs. Other certain non-marketable strategic investments are carried at cost and are subject to remeasurement only upon the occurrence of a triggering event.

Strategic Investments

Strategic investments that consist of non-controlling equity investments without readily determinable fair values in privately held companies for which the Company does not have the ability to exercise significant influence are measured under the measurement alternative method. The Company has not elected the fair value option for these investments. These investments are accounted for under the cost method of accounting. Under the cost method of accounting, the non-marketable equity securities are carried at cost less any impairment, plus or minus adjustments resulting from observable price changes in orderly transactions for the identical or a similar investment of the same issuer, which is recorded within the consolidated statements of operations. The Company held $20.0 million of strategic investments without readily determinable fair values at September 27, 2025 and no strategic investments without readily determinable fair values at September 28, 2024. These investments are included in other assets on the consolidated balance sheets.

The Company adjusts the fair values of its strategic investments based on observable price changes. There were no gains, losses, or impairments recorded for the year ended September 27, 2025.

The Company has certain other non-marketable strategic investments measured at fair value on a non-recurring basis. The Company has not elected the fair value option for these investments. The Company held $23.3 million of these investments at September 27, 2025. These investments are included in other assets on the consolidated balance sheets.

- Definition

The entire disclosure for the fair value of financial instruments (as defined), including financial assets and financial liabilities (collectively, as defined), and the measurements of those instruments as well as disclosures related to the fair value of non-financial assets and liabilities. Such disclosures about the financial instruments, assets, and liabilities would include: (1) the fair value of the required items together with their carrying amounts (as appropriate); (2) for items for which it is not practicable to estimate fair value, disclosure would include: (a) information pertinent to estimating fair value (including, carrying amount, effective interest rate, and maturity, and (b) the reasons why it is not practicable to estimate fair value; (3) significant concentrations of credit risk including: (a) information about the activity, region, or economic characteristics identifying a concentration, (b) the maximum amount of loss the entity is exposed to based on the gross fair value of the related item, (c) policy for requiring collateral or other security and information as to accessing such collateral or security, and (d) the nature and brief description of such collateral or security; (4) quantitative information about market risks and how such risks are managed; (5) for items measured on both a recurring and nonrecurring basis information regarding the inputs used to develop the fair value measurement; and (6) for items presented in the financial statement for which fair value measurement is elected: (a) information necessary to understand the reasons for the election, (b) discussion of the effect of fair value changes on earnings, (c) a description of [similar groups] items for which the election is made and the relation thereof to the balance sheet, the aggregate carrying value of items included in the balance sheet that are not eligible for the election; (7) all other required (as defined) and desired information.
