| Summary of Significant Accounting Policies | 2. Summary of Significant Accounting Policies Basis of Presentation and Preparation The consolidated financial statements, which include the accounts of Sonos, Inc. and its wholly owned subsidiaries, have been prepared in conformity with accounting principles generally accepted in the United States ("U.S. GAAP"). All intercompany accounts and transactions have been eliminated in consolidation. Certain prior period amounts have been reclassified to conform to the current period presentation. The Company operates on a 52-week or 53-week fiscal year ending on the Saturday nearest September 30 each year. The Company’s fiscal year is divided into four quarters of 13 weeks, each beginning on a Sunday and containing two 4-week periods followed by a 5-week period. An additional week is included in the fourth fiscal quarter approximately every five years to realign fiscal quarters with calendar quarters. This last occurred in the Company’s fiscal year ended October 3, 2020, and will reoccur in the fiscal year ending October 3, 2026. As used in the Annual Report on Form 10-K, “fiscal 2025” refers to the 52-week fiscal year ending September 27, 2025, “fiscal 2024” refers to the 52-week fiscal year ending September 28, 2024, and “fiscal 2023” refers to the 52-week fiscal year ending September 30, 2023. Use of Estimates and Judgments The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and judgments that affect the amounts reported and disclosed in the consolidated financial statements and accompanying notes. Actual results could differ materially from those estimates. For revenue recognition, examples of estimates and judgments include: determining the nature and timing of satisfaction of performance obligations, determining the standalone selling price ("SSP") of performance obligations and estimating variable consideration such as sales incentives and product returns. Additionally, management makes estimates and judgments for allowances for credit losses, excess and obsolete inventory, loss on purchase commitments, useful lives associated with property and equipment, incremental borrowing rates associated with leases, the recording of and release of valuation allowances with respect to deferred tax assets and uncertain tax positions, impairment of long-lived assets, impairment of goodwill and indefinite-lived intangible assets, warranty, contingencies and valuation and assumptions underlying stock-based compensation and other equity instruments. On an ongoing basis, the Company evaluates its estimates and judgments compared to historical experience and trends that form the basis for making estimates and judgments about the carrying value of assets and liabilities. Comprehensive Income (Loss) Comprehensive income (loss) consists of two components: net income (loss) and other comprehensive income (loss). Other comprehensive income (loss) refers to net gains and losses that are recorded as an element of stockholders’ equity but are excluded from net income (loss). The Company’s other comprehensive income (loss) consists of net unrealized gains and losses on foreign currency translation adjustments from those subsidiaries not using the U.S. dollar as their functional currency and unrealized gains and losses on marketable securities. Cash and Cash Equivalents Cash equivalents consist of short-term, highly liquid financial instruments with insignificant interest rate risk that are readily convertible to cash and have maturities of three months or less from the date of purchase. As of September 27, 2025, and September 28, 2024, cash equivalents consisted of money market funds, which are recorded at fair value. Marketable Securities The Company’s marketable securities consist of U.S. Treasury securities. Management determines the appropriate classification of its marketable securities at the time of purchase and reevaluates such determination at each balance sheet date. The Company classifies its marketable securities as available-for-sale and reports them at fair value in the consolidated balance sheets, with unrealized gains and losses recorded in accumulated other comprehensive loss. If securities are sold prior to maturity, the cost of securities sold is based on the specific identification method. Realized gains and losses on the sale of securities are recorded in other income (expense), net in the consolidated statements of operations and comprehensive loss. Classification of the Company's marketable securities in the consolidated balance sheets is based on each instrument’s underlying contractual maturity date. Securities with an original maturity of three months or less at time of purchase are recorded in cash and cash equivalents. Securities with an original maturity of greater than three months but less than one year are recorded in marketable securities. For securities in an unrealized loss position, the Company first assesses whether it intends to sell, or it is more-likely-than-not that it will be required to sell, the security before recovery of its amortized cost basis. If either of the criteria regarding intent or requirement to sell is met, the security's amortized cost basis is written down to fair value through earnings. For securities that do not meet the aforementioned criteria, the Company evaluates whether the decline in fair value has resulted from credit losses or other factors. In making this assessment, the Company considers the extent to which fair value is less than amortized cost, any changes to the rating of the security by a rating agency, and adverse conditions specifically related to the security, among other factors. If this assessment indicates that a credit loss exists, the present value of cash flows expected to be collected from the security is compared to the amortized cost basis of the security. If the present value of cash flows expected to be collected is less than the amortized cost basis, a credit loss exists and an allowance for credit losses is recorded for the credit loss, limited by the amount that the fair value is less than the amortized cost basis. Any impairment that has not been recorded through an allowance for credit losses is recognized in accumulated other comprehensive loss in the consolidated balance sheets. The Company has elected the practical expedient to exclude the applicable accrued interest from both the fair value and the amortized cost basis of its marketable securities for the purpose of identifying and measuring impairment. The Company presents accrued interest receivable related to its marketable securities in prepaid and other current assets, separate from marketable securities, on its consolidated balance sheets. The Company's accounting policy is to not measure an allowance for credit losses for accrued interest receivable and to write-off any uncollectible accrued interest receivable as a reversal of interest income in a timely manner, which it considers to be in the period in which it determines the accrued interest will not be collected. Accounts Receivable Accounts receivable are recorded at the invoiced amount, net of allowances for credit losses and sales incentives. Receivables do not require collateral and do not bear interest. The allowance for credit losses is established through a provision for expected credit losses, which is recorded as general and administrative expense in the consolidated statements of operations and comprehensive loss. The Company evaluates the adequacy of the allowance for credit losses by assessing the collectability of accounts receivable. This assessment considers the age of outstanding invoices, each customer’s payment history and expected ability to pay, customer-specific information, and current economic conditions that may affect collectability. The allowance estimate is reviewed and adjusted periodically, or when the Company becomes aware of specific factors indicating a customer’s inability to meet its financial obligations. Concentration of Credit Risk Financial instruments that potentially subject the Company to significant concentrations of credit risk consist principally of cash and cash equivalents, marketable securities, and accounts receivable. The Company maintains cash and cash equivalents and marketable securities in several high-quality financial institutions. Cash and cash equivalents held at these banks, including those held in foreign branches of global banks, may exceed the amount of insurance provided on such deposits. These deposits may be redeemed upon demand, and management believes that the financial institutions that hold the Company’s cash and cash equivalents are financially sound and, accordingly, minimal credit risk exists with respect to cash. The Company has not experienced any losses in such accounts. As of September 27, 2025, and September 28, 2024, the Company’s customers that accounted for 10% or more of total accounts receivable, net, were as follows:
The Company’s customer that accounted for 10% or more of total revenue were as follows:
Inventories Inventories primarily consist of finished goods and component parts, which are purchased from contract manufacturers and component suppliers. Inventories are stated at the lower of cost and net realizable value. Cost is determined using a standard costing method, which approximates first-in first-out. Inventory costs primarily consist of materials, inbound freight, import duties, tariffs, direct labor and manufacturing overhead, logistics, and other handling fees. The Company assesses the valuation of inventory balances including an analysis of determine potential excess and/or obsolete inventory. The Company may be required to write down the value of inventory if estimates of future demand and market conditions indicate excess and/or obsolete inventory. Inventory write-downs and losses on purchase commitments are recorded as a component of cost of revenue in the consolidated statements of operations and comprehensive loss. Losses related to purchase commitments for fiscal 2025 and fiscal 2024 were not material. Ownership of inventory transfers to the Company based on contractual terms with its contract manufacturers. Property and Equipment, Net Property and equipment are stated at historical cost less accumulated depreciation. Depreciation is calculated using the straight-line method over the estimated useful lives of the related assets as follows:
Costs incurred to improve leased office space are capitalized. Leasehold improvements are amortized on a straight-line basis over the shorter of the term of the lease or the estimated useful life of the improvement. Expenditures for major renewals and improvements that extend the useful lives of property and equipment are capitalized. Maintenance, repair costs and gains or losses associated with disposals are charged to expense as incurred. Product displays are deployed at retail locations. Because the product displays facilitate marketing of the Company’s products within the retail stores, depreciation for product displays is recorded in sales and marketing expenses in the consolidated statements of operations and comprehensive loss. Cloud Computing Arrangements The Company incurs costs to implement cloud computing arrangements that are hosted by a third-party vendor. For cloud computing arrangements that do not include a software license, implementation costs incurred during the application development stage are capitalized until the software is ready for its intended use. The costs are then amortized on a straight-line basis over the term of the associated hosting arrangement and are recognized as an operating expense within the consolidated statements of operations and comprehensive loss. Capitalized costs related to cloud computing arrangements, net of accumulated amortization, are reported as a component of other noncurrent assets on the Company's consolidated balance sheets. Impairment of Goodwill and Indefinite-lived Intangible Assets Goodwill and indefinite-lived intangible assets are not amortized and are tested for impairment on an annual basis during the third quarter of each fiscal year or between annual tests if an event occurs or circumstances change that would more likely than not reduce the fair value of the reporting unit or asset below its carrying value. In connection with the Company's evaluation of goodwill impairment, the Company performs a qualitative assessment to determine if it is more likely than not that the fair value of a reporting unit is less than its carrying amount. If the qualitative assessment is not conclusive, the Company tests goodwill for impairment, including comparing the fair value of the reporting unit to its carrying value (including attributable goodwill). The Company determines fair value of its reporting unit using an income or market approach incorporating market participant considerations and management’s assumptions on revenue growth rates, operating margins, discount rates and expected capital expenditures. Fair value determinations may include both internal and third-party valuations. In connection with the Company’s evaluation of indefinite-lived intangible asset impairment, the Company performs a qualitative assessment to determine if it is more likely than not that the fair value of the asset is less than its carrying amount. If the qualitative assessment is not conclusive, the Company proceeds to test for impairment by comparing the fair value of the asset to the carrying value. Fair value is determined based on estimated discounted future cash flow analyses that include significant management assumptions such as revenue growth rates, weighted-average costs of capital and assumed royalty rates. If the carrying value exceeds fair value, an impairment charge will be recorded to reduce the asset to fair value. For fiscal years 2025, 2024, and 2023, the Company’s qualitative assessments identified no factors indicating it was more likely than not that the fair value of the Company’s reporting unit and indefinite-lived intangible assets were less than their respective carrying amounts. Therefore, the Company incurred no impairment charges. Impairment of Long-Lived Assets The Company evaluates the recoverability of its long-lived assets, which primarily comprises property and equipment and operating lease right-of-use assets, for impairment whenever events or changes in circumstances indicate that the carrying amounts may not be recoverable. The Company performs impairment testing at the level that represents the lowest level for which identifiable cash flows are largely independent of the cash flows of other assets and liabilities. Recoverability is measured by comparing the carrying amounts to the expected future undiscounted cash flows attributable to the assets. If it is determined that an asset may not be recoverable, an impairment loss equal to the excess of the asset’s carrying value over its fair value is recorded. Fair value is determined based on estimated discounted future cash flows analyses. There were no impairment charges identified on the Company's long-lived assets during fiscal years 2025, 2024, and 2023. Product Warranties The Company’s products are covered by warranty to be free from defects in material and workmanship for a period of one year, except in the EU and select other countries where the Company provides a minimum two-year warranty, depending on the region. At the time of sale, an estimate of future warranty costs is recorded as a component of cost of revenue and a warranty liability is recorded for estimated costs to satisfy the warranty obligation. The Company’s estimate of costs to fulfill its warranty obligations is based on historical experience and expectations of future costs to repair or replace. Legal Contingencies If a potential loss from any claim or legal proceeding is considered probable, and the amount can be reasonably estimated, the Company records a liability for an estimated loss. Legal fees are expensed as incurred and included in general and administrative expenses in the consolidated statements of operations and comprehensive loss. See Note 12. Commitments and Contingencies for additional information regarding legal contingencies. Treasury Stock The Company accounts for treasury stock acquisitions using the cost method. The Company accounts for the retirement of treasury stock by deducting its par value from common stock and reflecting any excess of cost over par value as a deduction from additional paid-in capital on the consolidated balance sheets. Fair Value Accounting Assets and liabilities recorded at fair value on the consolidated balance sheets are categorized based upon the level of judgment associated with the inputs used to measure their fair value. Fair value is estimated by applying the following hierarchy, which prioritizes the inputs used to measure fair value into three levels and bases the categorization within the hierarchy upon the lowest level of input that is available and significant to the fair value measurement:
Foreign Currency Certain of the Company’s wholly owned subsidiaries have non-U.S. dollar functional currencies. The Company translates assets and liabilities of non-U.S. dollar functional currency subsidiaries into U.S. dollars using exchange rates in effect at the end of each period and stockholders’ equity at historical rates. Revenue and expenses for these subsidiaries are translated using rates that approximate those in effect during the period. Gains and losses from translation are recognized in foreign currency translation included in accumulated other comprehensive loss. The Company remeasures monetary assets or liabilities denominated in currencies other than the functional currency using exchange rates prevailing on the balance sheet date, and non-monetary assets and liabilities at historical rates. Foreign currency remeasurement and transaction gains and losses are included in other income (expense), net. Foreign currency remeasurement and transaction gains (losses) are recorded in other income (expense), net as follows:
Revenue Recognition Revenue is recognized upon transfer of control of promised products or services to customers in an amount that reflects the consideration the Company expects to receive in exchange for those products or services. Revenue is recognized net of allowances for returns, discounts, sales incentives, and any taxes collected from customers. The Company defers a portion of revenue that is allocated to unspecified software upgrades and cloud-based services, as well as for newly launched products sold to resellers not recognized until the date of general availability is reached. The Company's contracts generally include a combination of products and services. Revenue is allocated to distinct performance obligations and is recognized net of allowances for returns, discounts, sales incentives and any taxes collected from customers, which are subsequently remitted to governmental authorities. Shipping and handling costs associated with outbound freight after control over a product has transferred to a customer are not considered a separate performance obligation and are accounted for as a fulfillment cost and are included in cost of revenue. Nature of Products and Services Product revenue primarily includes sales of Sonos speakers and Sonos system products, which include software that enables the Company’s products to operate over a customer’s wireless network, as well as connect to various third-party services, including music and voice. The Company also generates a small portion of revenue from Partner products and other revenue sources in connection with partnerships, accessories, professional services, licensing, advertising, and subscription revenue. Revenue for module units is related to hardware and embedded software that is integrated into final products that are manufactured and sold by the Company's partners. Software primarily consists of firmware embedded in the products and the Sonos app, which is software that can be downloaded to consumer devices at no charge, with or without the purchase of one of the Company’s products. Products and related software are accounted for as a single performance obligation and all intended functionality is available to the customer upon purchase. The revenue allocated to the products and related software is the substantial portion of the total sale price. Product revenue is recognized at the point in time when control is transferred, which is either upon shipment or upon delivery to the customer, depending on delivery terms. Service revenue includes revenue allocated to (i) unspecified software upgrades and (ii) cloud-based services that enable products to access third-party music and voice assistant platforms, based on relative standalone selling price, which are each distinct performance obligations and are provided to customers at no additional charge. Unspecified software upgrades are provided on a when-and-if-available basis and have historically included updates and enhancements such as bug fixes, feature enhancements and updates to the ability to connect to third-party music or voice assistant platforms. Service revenue is recognized ratably over the estimated service period. Significant Judgments The Company’s contracts with customers generally contain promises to transfer products and services as described above. Determining whether products and services are considered distinct performance obligations that should be accounted for separately requires significant judgment. Determining the SSP for each distinct performance obligation requires judgment. The Company estimates SSP for items that are not sold separately, which include the products and related software, unspecified software upgrades and cloud-based services, using information that may include competitive pricing information, where available, as well as analyses of the cost of providing the products or services plus a reasonable margin. In developing SSP estimates, the Company also considers the nature of the products and services and the expected level of future services. Determining the revenue recognition period for unspecified software upgrades and cloud-based services also requires judgment. The Company recognizes revenue attributable to these performance obligations ratably over the best estimate of the period that the customer is expected to receive the services. In developing the estimated period of providing future services, the Company considers past history, plans to continue to provide services, including plans to continue to support updates and enhancements to prior versions of the Company’s products, expected technological developments, obsolescence, competition and other factors. The estimated service period may change in the future in response to competition, technology developments and the Company’s business strategy. The Company offers sales incentives through various programs consisting primarily of discounts, cooperative advertising and market development fund programs. The Company records cooperative advertising and market development fund programs with customers as a reduction to revenue unless it receives a distinct benefit in exchange for credits claimed by the customer and can reasonably estimate the fair value of the benefit received, in which case the Company records it as an expense. The Company recognizes a liability or a reduction to accounts receivable, and reduces revenue based on the estimated amount of sales incentives that will be claimed by customers. Estimates for sales incentives are developed using the most likely amount and are included in the transaction price to the extent that a significant reversal of revenue would not result once the uncertainty is resolved. In developing its estimate, the Company also considers the susceptibility of the incentive to outside influences, the length of time until the uncertainty is resolved and the Company’s experience with similar contracts. Reductions in revenue related to discounts are allocated to products and services on a relative basis based on their respective SSP. Judgment is required to determine the timing and amount of recognition of marketing funds which the Company estimates based on past practice of providing similar funds. The Company accepts returns from direct customers and from certain resellers. To establish an estimate for returns, the Company uses the expected value method by considering a portfolio of contracts with similar characteristics to calculate the historical returns rate. When determining the expected value of returns, the Company considers future business initiatives and relevant anticipated future events. Supplier Concentration The Company relies on third parties for the supply and manufacture of its products, as well as third-party logistics providers for the distribution of its products. In instances where these parties fail to perform their obligations, the Company may be unable to find alternative suppliers or satisfactorily deliver its products to customers on time, if at all. During fiscal years 2025, 2024 and 2023, approximately 53%, 60% and 58%, respectively, of the Company’s finished goods purchased during each year were from one vendor. Deferred Revenue and Payment Terms The Company invoices each order upon hardware shipment or delivery and recognizes revenue for each distinct performance obligation when transfer of control has occurred, which in the case of services, may extend over several reporting periods. Amounts invoiced in advance of revenue recognition are recorded as deferred revenue on the consolidated balance sheets. Deferred revenue primarily relates to revenue allocated to unspecified software upgrades and platform services, as well as for newly launched products sold to resellers not recognized until the date of general availability is reached. General availability deferrals are classified as current deferred revenue as the Company starts shipping the product to the reseller within one month prior to the general availability date. The Company classifies deferred revenue as noncurrent if amounts are expected to be recognized as revenue beyond one year from the balance sheet date. Payment Terms Payment terms and conditions vary among the Company’s distribution channels although terms generally include a requirement of payment within 30 days of product shipment. Sales directly to customers from the Company’s website are paid at the time of product shipment. Prior to providing payment terms to customers, an evaluation of the customer’s credit risk is performed. Contractual allowances are an offset to accounts receivable. Research and Development Research and development expenses consist primarily of personnel-related expenses, consulting and outside professional service costs, tooling and prototype materials and overhead costs. Substantially all of the Company’s research and development expenses are related to developing new products and services and improving existing products and services. To date, software development costs have been expensed as incurred because the period between achieving technological feasibility and the release of the software has been short and development costs qualifying for capitalization have been insignificant. In-process research and development ("IPRD") assets represent the fair value of incomplete research and development projects obtained as part of a business combination that have not yet reached technological feasibility and are initially not subject to amortization; rather, these assets are subject to impairment considerations of indefinite-lived intangible assets. Upon completion of development, IPRD assets are considered definite-lived intangible assets, transferred to developed technology and are amortized over their useful lives. If a project were to be abandoned, the IPRD would be considered fully impaired and expensed to research and development. Advertising Costs Advertising costs are expensed as incurred and included in sales and marketing expenses. Advertising expenses were $42.8 million, $55.8 million and $43.9 million for fiscal 2025, 2024 and 2023, respectively. Restructuring and Related Costs Costs associated with a restructuring plan generally consist of involuntary employee termination benefits, contract termination costs, and other exit-related costs including costs to close facilities. The Company records a liability for involuntary employee termination benefits when management has committed to a plan that establishes the terms of the arrangement and that plan has been communicated to employees. Costs to terminate a contract before the end of the term are recognized on the termination date, and costs that will continue to be incurred in a contract for the remaining term without economic benefit are recognized as of the cease-use date. Restructuring and related costs may also include the write-down of related assets, including operating lease right-of-use assets, when the sale or abandonment of the asset is a direct result of the plan. Other exit-related costs are recognized as incurred. Restructuring and related costs are recognized as within operating expenses and cost of revenue within the consolidated statements of operations and comprehensive loss and are classified based on the Company's classification policy for each category of operating expense. Stock-Based Compensation The Company measures stock-based compensation cost at fair value on the date of grant. Compensation cost for stock options is recognized, on a straight-line basis, as an expense over the period of vesting as the employee performs the related services, net of estimated forfeitures. The Company estimates the fair value of stock option awards using the Black-Scholes option-pricing model and is based on the Company’s closing stock price on the trading day immediately prior to the date of grant. The Company estimates forfeitures based on expected future terminations and will revise rates, as necessary, in subsequent periods if actual forfeitures differ from initial estimates. The fair value of RSUs is based on the Company's closing stock price on the trading day immediately preceding the date of grant. The Company estimates the fair value of performance stock units ("PSU") on the grant date and recognizes compensation expense in the period it becomes probable that performance conditions will be achieved. On a quarterly basis, the Company re-evaluates the assumption of the probability that performance conditions will be satisfied and revises its estimates as appropriate as new or updated information becomes available. Retirement Plans The Company has a defined contribution 401(k) plan (the "401(k) Plan") for the Company’s U.S.-based employees, as well as various defined contribution plans for its international employees. Eligible U.S. employees may make tax-deferred contributions under the 401(k) plan, but are limited to the maximum annual dollar amount allowable under the Internal Revenue Code of 1986, as amended (the "Code"). The Company matches contributions towards the 401(k) Plan and international defined contribution plans. The Company's matching contributions totaled $7.8 million, $9.5 million, and $9.5 million for fiscal 2025, fiscal 2024, and 2023, respectively. Income Taxes The Company accounts for income taxes under the asset and liability method, which requires the recognition of deferred tax assets and liabilities for the expected future tax consequences of events that have been included in the consolidated financial statements. Under this method, deferred tax assets and liabilities are determined based on 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 differences are expected to reverse. The effect of a change in tax rates on deferred tax assets and liabilities is recognized in income during the period that includes the enactment date. The Company records a valuation allowance when necessary to reduce its deferred tax assets to amounts that are more likely than not to be realized. In making such a determination, all available positive and negative evidence is considered, including future reversals of existing taxable temporary differences, projected future taxable income, tax-planning strategies, and results of recent operations. If the Company determines that it would be able to realize its deferred tax assets in the future in excess of their net recorded amount, the Company would make an adjustment to the deferred tax asset valuation allowance, which would result in a benefit to income taxes. The Company records uncertain tax positions in accordance with a two-step process whereby (i) the Company determines whether it is more likely than not that the tax positions will be sustained on the basis of the technical merits of the position and (ii) for those tax positions that meet the more likely than not recognition threshold, the Company recognizes the largest amount of tax benefit that is more than 50% likely to be realized upon ultimate settlement with the related tax authority. The Company includes interest and penalties related to unrecognized tax benefits within the provision for income taxes in the consolidated statements of operations and comprehensive loss. The Company has not incurred any interest or penalties related to unrecognized tax benefits in any of the periods presented. The Company’s provision for (benefit from) income taxes, deferred tax assets and liabilities, and liabilities for unrecognized tax benefits involves the use of estimates, assumptions and judgments. Although the Company believes its estimates, assumptions and judgments to be reasonable, any changes in tax law or its interpretation of tax laws and the resolutions of potential tax audits could significantly impact the amounts provided for income taxes in the Company’s consolidated financial statements. Actual future operating results and the underlying amount and type of income could differ materially from the Company’s estimates, assumptions and judgments thereby impacting the Company’s financial position and results of operations. Segment Information The Company operates as one operating segment as it only reports aggregate financial information on a consolidated basis, accompanied by disaggregated information about revenue by geographic region and product category, to its Chief Executive Officer, who is the Company’s Chief Operating Decision Maker ("CODM"). The CODM reviews financial information on a consolidated basis for purposes of making operating decisions, allocating resources, and evaluating financial performance. The CODM uses consolidated net income (loss) to measure segment profit or loss and make key operating decisions, such as allocation of the budget and monitoring budget versus actual results. Significant expenses within net income (loss) include cost of revenue, research and development, sales and marketing, and general and administrative, which are each separately presented on the Company’s consolidated statements of operations and comprehensive loss. Other segment items include interest income, interest expense, other income (expense), and provision for income taxes, which are also each separately presented on the Company’s consolidated statements of operations and comprehensive loss. The CODM does not evaluate segment performance or allocate resources using asset information. Leases The majority of the Company’s leases are for its office spaces and facilities, which are accounted for as operating leases. The Company leases office space in California, as well as offices in various locations in the U.S., with additional sales, operations, and research and development offices around the world. The Company determines whether an arrangement is a lease at inception if there is an identified asset, and if it has the right to control the identified asset for a period of time. Some of the Company’s leases include options to extend the leases for up to 5 years, and some include options to terminate the leases. The Company's lease terms are only for periods in which it has enforceable rights and are impacted by options to extend or terminate the lease only when it is reasonably certain that the Company will exercise the option. For leases with terms greater than 12 months, the Company records the related right-of-use asset and lease obligation at the present value of lease payments over the lease terms. Leases with an initial term of 12 months or less are not recorded on the balance sheet. Lease expense is recognized on a straight-line basis over the lease term. The Company's leases do not include any residual value guarantees or bargain purchase options. Lease agreements will typically exist with lease and non-lease components, which are accounted for separately. The Company's agreements may contain variable lease payments. The Company includes variable lease payments that depend on an index or a rate and exclude those which depend on facts or circumstances occurring after the commencement date, other than the passage of time. As most of the Company’s leases do not contain an implicit interest rate, the Company uses judgment to determine an incremental borrowing rate, which is defined as the rate of interest the Company would have to pay to borrow an amount that is equal to the lease obligations, on a collateralized basis, and over a similar term. The Company takes into consideration the terms of the Company's Credit Facility (as defined in Note 7. Debt), lease terms, and current interest rates to determine the incremental borrowing rate at lease commencement date.

| Financial Instruments | 3. Financial Instruments The carrying values of the Company’s accounts receivable and accounts payable, approximate their fair values due to the short period of time to maturity or repayment. The following table summarizes cash, cash equivalents and marketable securities by investment category as of September 27, 2025, and September 28, 2024:
Marketable Securities As of September 27, 2025, and September 28, 2024, the Company held no securities with original maturities exceeding one year. There were no realized gains or losses on sales of marketable securities during fiscal 2025, and fiscal 2024. For securities in an unrealized loss position, the Company does not intend to sell the securities, and it is more-likely-than-not that it will not be required to sell before recovery of their amortized cost basis. The Company evaluated whether the decline in fair value resulted from credit losses or other factors and concluded these amounts were related to temporary fluctuations in value of the securities and were due primarily to changes in interest rates and market conditions of the underlying securities. Accordingly, an allowance for credit losses was deemed unnecessary for these securities as of September 27, 2025. Accrued interest receivable related to our marketable securities was nominal as of September 27, 2025, and September 28, 2024. No accrued interest receivables were written off during fiscal 2025, and fiscal 2024.

| Income Taxes | 10. Income Taxes The Company’s income (loss) before provision for income taxes for fiscal 2025, 2024 and 2023 were as follows:
Components of the provision for income taxes consisted of the following:
The Company is subject to income taxes in the United States and foreign jurisdictions in which it operates. The Company’s tax provision is impacted by the jurisdictional mix of earnings as its foreign subsidiaries have statutory tax rates different from those in the United States. Accordingly, the Company's effective tax rate will vary depending on jurisdictional mix of earnings and changes in tax laws. For fiscal 2025, the Company’s U.S. tax expense was adversely impacted by the requirement to capitalize and amortize research and development expenses under Section 174 of the U.S. Internal Revenue Code ("Section 174") as the Company recorded a current U.S. tax expense with no corresponding deferred tax benefit due to the valuation allowance maintained against its U.S. deferred tax assets. Components of the Company’s deferred income tax assets and liabilities are as follows:
Deferred income taxes reflect the net tax effects of temporary differences between the carrying amounts of assets and liabilities for financial reporting purposes and the amounts used for income tax purposes. A valuation allowance is provided to reduce the Company's deferred tax assets to amounts that are more-likely-than-not to be realized. The Company has assessed, on a jurisdictional basis, the realization of its net deferred tax assets, including the ability to carry back net operating losses, the existence of taxable temporary differences, the availability of tax planning strategies and available sources of future taxable income. The Company has concluded that based on cumulative taxable income and future taxable income that it is able to realize a benefit for net deferred tax assets in all non-U.S. jurisdictions. In addition, the Company has concluded that a valuation allowance on its net deferred tax assets in the U.S. continues to be appropriate considering cumulative taxable losses in recent years and uncertainty with respect to future taxable income. It is possible that within the next 12 months there may be sufficient positive evidence to release a portion or all of the remaining valuation allowance in the U.S. Release of the remaining valuation allowance would result in a benefit to income tax expense for the period the release is recorded, which could have a material impact on net earnings. The timing and amount of the potential valuation allowance release are subject to significant management judgment, as well as prospective earnings in the United States. For fiscal 2025, the Company had gross state net operating loss carryforwards of $58.2 million, which expire beginning in 2032, as well as $37.8 million in foreign net operating loss carryforwards with an indefinite life. As of September 27, 2025, the Company also had U.S. federal research and development tax credit carryforwards as filed of $30.1 million, and state research and development tax credit carryforwards as filed of $50.2 million, which will expire beginning in 2042 and 2026, respectively. The federal and state research and development tax credits are shown net of uncertain tax positions and net of federal benefit, as applicable, in the components of the Company's deferred income tax assets and liabilities. For fiscal 2025, the increase in capitalized research and development relates to the requirement to capitalize research and development expenses under Section 174. Because of the change of ownership provisions of Sections 382 and 383 of the Internal Revenue Code, and similar state provisions, use of a portion of the Company’s U.S. federal and state net operating loss and research and development tax credit carryforwards may be limited in future periods if there are future changes in ownership. Further, a portion of the carryforwards may expire before being applied to reduce future taxable income and income tax liabilities if sufficient taxable income is not generated in future periods. The following table summarizes changes in the valuation allowance for fiscal 2025, 2024 and 2023:
Reconciliation of U.S. statutory federal income taxes to the Company’s provision for income taxes is as follows:
Change in gross unrecognized tax benefits, excluding interest and penalties, as a result of uncertain tax positions are as follows:
The Company does not anticipate changes to its unrecognized benefits within the next 12 months that would result in a material change to the Company’s financial position. The unrecognized tax benefits as of September 27, 2025, would have no impact on the effective tax rate if recognized. The Company conducts business in a number of jurisdictions and, as such, is required to file income tax returns in multiple jurisdictions globally. U.S. federal income tax returns for the 2021 tax year and earlier are no longer subject to examination by the U.S. Internal Revenue Service (the "IRS"). All U.S. federal and state net operating losses as well as research and development tax credits generated to date, including 2021 and earlier, used in open tax years are subject to adjustment by the IRS and state tax authorities. The Company recognizes interest and penalties, if any, related to uncertain tax positions in income tax expense. There were no accrued interest or penalties as of September 27, 2025, and September 28, 2024. As of September 27, 2025, the Company continues to assert that the unremitted earnings in our foreign subsidiaries are permanently reinvested and therefore no deferred taxes or withholding taxes have been provided. If, in the future, the Company decides to repatriate its $16.3 million of undistributed earnings from these subsidiaries in the form of dividends or otherwise, the Company could be subject to withholding taxes payable at that time. Outside basis differences in the Company's foreign subsidiaries including unremitted earnings and any related taxes are not material. On July 4, 2025, H.R.1, commonly referred to as the One Big Beautiful Bill Act (“OBBBA”) was enacted. The legislation includes provisions such as accelerated cost recovery of qualified property, immediate expensing of U.S.-based research and development costs, and changes to the U.S. international taxation regime. The Company has evaluated the impact of the OBBBA and determined that it did not have a material effect on its fiscal 2025 consolidated financial statements.

| Loss Per Share | 11. Loss Per Share Basic loss per share attributable to common stockholders is calculated by dividing loss attributable to common stockholders by the weighted-average number of shares of common stock outstanding less shares subject to repurchase. Diluted loss per share attributable to common stockholders adjusts the basic loss per share attributable to common stockholders and the weighted-average number of shares of common stock outstanding for the potentially dilutive impact of stock awards, using the treasury stock method. The following table sets forth the computation of the Company’s basic and diluted loss per share attributable to common stockholders:
The following potentially dilutive shares as of the end of each period presented were excluded from the computation of diluted loss per share for the periods presented because including them would have been antidilutive:

| Commitments and Contingencies Disclosure [Abstract] | |
| Commitments and Contingencies | 12. Commitments and Contingencies Commitments to suppliers The Company utilizes contract manufacturers to build its products. These contract manufacturers acquire components and build products based on demand forecast information the Company supplies, which typically covers twelve months. Consistent with industry practice, the Company acquires inventories from such manufacturers through blanket purchase orders which are based on projected demand information and availability of goods. Such purchase commitments typically cover the Company's forecasted product and manufacturing requirements for periods that range a number of months. In certain instances, these agreements allow the Company the option to cancel, reschedule, and/or adjust our requirements based on its business needs for a period of time before the order is due to be fulfilled. The Company's purchase orders typically are not cancellable in the event of a demand plan change or other circumstances, such as where the supplier has procured unique, Sonos-specific designs, and/or specific non-cancellable, non-returnable components based on our provided forecasts. The expected commitments are subject to change as a result of fluctuations in the demand forecast, as well as ongoing negotiations with contract manufacturers and suppliers. These commitments are related to components that can be specific to Sonos products and comprised 1) indirect obligations to third-party manufacturers and suppliers, 2) the inventory owned by contract manufacturers procured to manufacture Sonos products, and 3) purchase commitments made by contract manufacturers to their upstream suppliers. Legal Proceedings From time to time, the Company is involved in legal proceedings in the ordinary course of business, including claims relating to employee relations, business practices, and patent infringement. Litigation can be expensive and disruptive to normal business operations. Moreover, the results of complex legal proceedings are difficult to predict, and the Company’s view of these matters may change in the future as the litigation and events related thereto unfold. The Company expenses legal fees as incurred. The Company records a provision for contingent losses when it is both probable that a liability has been incurred and the amount of the loss can be reasonably estimated. An unfavorable outcome to any legal matter, if material, could have an adverse effect on the Company’s operations or its financial position, liquidity or results of operations. The Company’s Lawsuits Against Google: On January 7, 2020, the Company filed a complaint with the U.S. International Trade Commission ("ITC") against Alphabet Inc. ("Alphabet") and Google LLC ("Google") and a counterpart lawsuit in the U.S. District Court for the Central District of California against Google. The complaint and lawsuit each allege infringement by Alphabet and Google of certain Sonos patents related to its smart speakers and related technology. The counterpart lawsuit was stayed pending completion of the ITC investigation and appeal thereof. The ITC concluded its investigation in January 2022, finding all five of the Company’s asserted patents to be valid and infringed by Google, and further finding that one redesign per patent proposed by Google would avoid infringement. The ITC issued a limited exclusion order and a cease-and-desist order with respect to Google’s infringing products. The Company and Google each appealed the ITC’s determination, which was upheld in its entirety by the appeals court. The stay in the counterpart lawsuit has been lifted. Google moved to file counterclaims on two of its own patents related to device setup and the court has added those patents to the case. No trial date has been set. On September 29, 2020, the Company filed another lawsuit against Google alleging infringement of additional Sonos patents and seeking monetary damages and other non-monetary relief. A jury trial was held in May 2023, which found one Sonos patent to be infringed and another Sonos patent not infringed, and returned an award of $32.5 million based on a royalty rate of $2.30 per infringing unit. After trial, the court held Sonos’ patents unenforceable under the doctrine of prosecution laches and invalid as a result of amendments made during prosecution. In September 2025, the Federal Circuit overturned the lower court decision that had invalidated the jury verdict against Google, and is now set to decide the post-trial motions, including the Company’s motion for injunctive relief and additional damages. Google’s Lawsuits Against the Company: On June 11, 2020, Google filed a lawsuit in the U.S. District Court for the Northern District of California against the Company alleging infringement by the Company of five Google patents and seeking monetary damages and other non-monetary relief. All five of these patents have since been found invalid or non-infringed by the Court or by the U.S. Patent and Trademark Office or have been withdrawn from the case by Google. The Court has now entered final judgment for Sonos and against Google. Google has appealed the non-infringement rulings. On August 8, 2022, Google filed two complaints with the ITC against the Company and two counterpart lawsuits in the Northern District of California against the Company, collectively alleging infringement by the Company of seven Google patents generally related to wireless charging, device setup, and voice control, and seeking monetary damages and other non-monetary relief. The counterpart lawsuits are stayed pending completion of the ITC investigations. In the first ITC investigation, the ITC terminated the investigation as to one Google patent as a result of the expiration of that Google patent and determined the other two Google patents to be invalid as indefinite, thus concluding the first investigation. Google has appealed this first ITC determination. The second ITC investigation concluded in December 2023 with a final determination of no violation by the Company. Google did not appeal this determination. Implicit On March 10, 2017, Implicit, LLC (“Implicit”) filed a patent infringement action in the United States District Court, District of Delaware against the Company. Implicit is asserting that the Company has infringed on certain claims of two patents in this case. The Company denies the allegations. The claims at issue have been held unpatentable by the U.S. Patent and Trademark Office. Implicit has appealed this ruling, which is currently scheduled to be heard by the appeals court in 2025. A range of loss, if any, associated with this matter is not probable or reasonably estimable as of September 27, 2025. The Company is involved in certain other litigation matters not listed above but does not consider these matters to be material either individually or in the aggregate at this time. The Company’s view of the matters not listed may change in the future as the litigation and events related thereto unfold. Guarantees and Indemnifications In the normal course of business, the Company enters into agreements that contain a variety of representations and warranties and provide for general indemnification. The Company’s exposure under these agreements is unknown because it involves claims that may be made against the Company in the future, but have not yet been made. To date, the Company has not incurred material costs to defend lawsuits or settle claims related to these indemnification provisions. The Company has also entered into indemnification agreements with its directors and officers that may require the Company to indemnify its directors and officers against liabilities that may arise by reason of their status or service as directors or officers to the fullest extent permitted by the Delaware General Corporation Law. The Company also currently has directors’ and officers’ insurance. No amount has been accrued in the consolidated financial statements with respect to these indemnification guarantees.

| Restructuring and Other Charges | 13. Restructuring and Other Charges The Company started a cost transformation initiative in the second half of fiscal 2024 with the goal of optimizing investments for sustainable, long-term growth. This included the August 14, 2024 initiation of a restructuring plan (the "2024 restructuring plan") that involved a reduction in force of approximately 6% of its employees and a reduction to its real estate footprint. In furtherance of this initiative, the Company announced a subsequent restructuring on February 5, 2025, including a reduction in force involving approximately 12% of its employees (the “2025 restructuring plan”). This cost transformation also involved non-recurring charges related to rationalization of its product roadmap and costs related to write-offs of assets no longer in use. Furthermore, in January 2025, Patrick Spence stepped down from his role as Chief Executive Officer ("CEO") and as a member of the Board, resulting in the Company incurring costs related to this transition, which are also included in restructuring and other charges. The following table summarizes the components of restructuring and other charges:
(1)Other restructuring charges include estimated costs primarily related to rationalization of the Company's product roadmap. (2)Non-cash charges for stock-based awards were related to modifications for equity awards primarily in connection with the CEO transition. These modifications included accelerated vesting of certain RSUs and an extension of the post-termination exercise period for certain stock options. The following table summarizes restructuring and other charges recorded in the Company's consolidated statements of operations and comprehensive loss:

| Cybersecurity Risk Management, Strategy, and Governance [Line Items] | |
| Cybersecurity Risk Management Processes for Assessing, Identifying, and Managing Threats [Text Block] | We have developed and implemented an enterprise-wide cybersecurity program, which is part of our overall risk management system and is designed to provide cybersecurity risk management and governance. Our cybersecurity program prioritizes, among other things, proactive detection and mitigation of threats; protection of customer and internal confidential information; minimization of the impact of incidents; and identification, assessment, and management of material risks from cybersecurity threats. We use a variety of strategies and techniques designed to identify cybersecurity risks and reduce the risk of unauthorized access to internal and customer confidential information and critical business systems and platforms. This approach utilizes both internal and external resources and includes regular risk assessments (for example, penetration testing and annual self-assessments), ongoing employee training, proactive monitoring of our IT systems, encryption of certain types of information, and certain controls governing access to our facilities and systems. We maintain a detailed incident response plan to manage cybersecurity incidents when detected. The response plan includes procedures for identifying, containing, and responding to cybersecurity incidents. Our ability to respond to cybersecurity incidents is tested on a recurring basis. We use third-party service providers to assist us from time to time to identify, assess, and manage material risks from cybersecurity threats, including professional services firms, cybersecurity software providers, and certain testing firms. We have processes in place designed to identify and mitigate risks from third-party vendors, including, as appropriate, pre-contractual security assessments and review of contractual terms addressing cybersecurity and data protection. To date, we are not aware of cybersecurity threats, including as a result of any previous cybersecurity incidents, that have materially affected or are reasonably likely to materially affect us, including our business strategy, results of operations or financial condition. Despite our security measures, however, there can be no assurance that we, or third parties with which we interact, will not experience a cybersecurity incident in the future that will materially affect us. For a discussion regarding risks related to cybersecurity threats, refer to Item 1A. “Risk Factors” of this Form 10-K.

||||||||||||||||||||||||||||||||||||
| Fiscal Period | The Company operates on a 52-week or 53-week fiscal year ending on the Saturday nearest September 30 each year. The Company’s fiscal year is divided into four quarters of 13 weeks, each beginning on a Sunday and containing two 4-week periods followed by a 5-week period. An additional week is included in the fourth fiscal quarter approximately every five years to realign fiscal quarters with calendar quarters. This last occurred in the Company’s fiscal year ended October 3, 2020, and will reoccur in the fiscal year ending October 3, 2026. As used in the Annual Report on Form 10-K, “fiscal 2025” refers to the 52-week fiscal year ending September 27, 2025, “fiscal 2024” refers to the 52-week fiscal year ending September 28, 2024, and “fiscal 2023” refers to the 52-week fiscal year ending September 30, 2023.

| Use of Estimates and Judgments | The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and judgments that affect the amounts reported and disclosed in the consolidated financial statements and accompanying notes. Actual results could differ materially from those estimates. For revenue recognition, examples of estimates and judgments include: determining the nature and timing of satisfaction of performance obligations, determining the standalone selling price ("SSP") of performance obligations and estimating variable consideration such as sales incentives and product returns. Additionally, management makes estimates and judgments for allowances for credit losses, excess and obsolete inventory, loss on purchase commitments, useful lives associated with property and equipment, incremental borrowing rates associated with leases, the recording of and release of valuation allowances with respect to deferred tax assets and uncertain tax positions, impairment of long-lived assets, impairment of goodwill and indefinite-lived intangible assets, warranty, contingencies and valuation and assumptions underlying stock-based compensation and other equity instruments. On an ongoing basis, the Company evaluates its estimates and judgments compared to historical experience and trends that form the basis for making estimates and judgments about the carrying value of assets and liabilities.

| Comprehensive Income (Loss) | Comprehensive income (loss) consists of two components: net income (loss) and other comprehensive income (loss). Other comprehensive income (loss) refers to net gains and losses that are recorded as an element of stockholders’ equity but are excluded from net income (loss). The Company’s other comprehensive income (loss) consists of net unrealized gains and losses on foreign currency translation adjustments from those subsidiaries not using the U.S. dollar as their functional currency and unrealized gains and losses on marketable securities.
|
||||||||||||||||||||||||||||||||||||
| Cash and Cash Equivalents | Cash equivalents consist of short-term, highly liquid financial instruments with insignificant interest rate risk that are readily convertible to cash and have maturities of three months or less from the date of purchase. As of September 27, 2025, and September 28, 2024, cash equivalents consisted of money market funds, which are recorded at fair value.
|
||||||||||||||||||||||||||||||||||||
| Marketable Securities | The Company’s marketable securities consist of U.S. Treasury securities. Management determines the appropriate classification of its marketable securities at the time of purchase and reevaluates such determination at each balance sheet date. The Company classifies its marketable securities as available-for-sale and reports them at fair value in the consolidated balance sheets, with unrealized gains and losses recorded in accumulated other comprehensive loss. If securities are sold prior to maturity, the cost of securities sold is based on the specific identification method. Realized gains and losses on the sale of securities are recorded in other income (expense), net in the consolidated statements of operations and comprehensive loss. Classification of the Company's marketable securities in the consolidated balance sheets is based on each instrument’s underlying contractual maturity date. Securities with an original maturity of three months or less at time of purchase are recorded in cash and cash equivalents. Securities with an original maturity of greater than three months but less than one year are recorded in marketable securities. For securities in an unrealized loss position, the Company first assesses whether it intends to sell, or it is more-likely-than-not that it will be required to sell, the security before recovery of its amortized cost basis. If either of the criteria regarding intent or requirement to sell is met, the security's amortized cost basis is written down to fair value through earnings. For securities that do not meet the aforementioned criteria, the Company evaluates whether the decline in fair value has resulted from credit losses or other factors. In making this assessment, the Company considers the extent to which fair value is less than amortized cost, any changes to the rating of the security by a rating agency, and adverse conditions specifically related to the security, among other factors. If this assessment indicates that a credit loss exists, the present value of cash flows expected to be collected from the security is compared to the amortized cost basis of the security. If the present value of cash flows expected to be collected is less than the amortized cost basis, a credit loss exists and an allowance for credit losses is recorded for the credit loss, limited by the amount that the fair value is less than the amortized cost basis. Any impairment that has not been recorded through an allowance for credit losses is recognized in accumulated other comprehensive loss in the consolidated balance sheets. The Company has elected the practical expedient to exclude the applicable accrued interest from both the fair value and the amortized cost basis of its marketable securities for the purpose of identifying and measuring impairment. The Company presents accrued interest receivable related to its marketable securities in prepaid and other current assets, separate from marketable securities, on its consolidated balance sheets. The Company's accounting policy is to not measure an allowance for credit losses for accrued interest receivable and to write-off any uncollectible accrued interest receivable as a reversal of interest income in a timely manner, which it considers to be in the period in which it determines the accrued interest will not be collected.

| Accounts Receivable | |||||||||||||||||||||||||||||||||||||
| Concentration of Credit Risk | Financial instruments that potentially subject the Company to significant concentrations of credit risk consist principally of cash and cash equivalents, marketable securities, and accounts receivable. The Company maintains cash and cash equivalents and marketable securities in several high-quality financial institutions. Cash and cash equivalents held at these banks, including those held in foreign branches of global banks, may exceed the amount of insurance provided on such deposits. These deposits may be redeemed upon demand, and management believes that the financial institutions that hold the Company’s cash and cash equivalents are financially sound and, accordingly, minimal credit risk exists with respect to cash. The Company has not experienced any losses in such accounts.
|
||||||||||||||||||||||||||||||||||||
| Inventories | Inventories primarily consist of finished goods and component parts, which are purchased from contract manufacturers and component suppliers. Inventories are stated at the lower of cost and net realizable value. Cost is determined using a standard costing method, which approximates first-in first-out. Inventory costs primarily consist of materials, inbound freight, import duties, tariffs, direct labor and manufacturing overhead, logistics, and other handling fees. The Company assesses the valuation of inventory balances including an analysis of determine potential excess and/or obsolete inventory. The Company may be required to write down the value of inventory if estimates of future demand and market conditions indicate excess and/or obsolete inventory. Inventory write-downs and losses on purchase commitments are recorded as a component of cost of revenue in the consolidated statements of operations and comprehensive loss. | ||||||||||||||||||||||||||||||||||||
| Property and Equipment, Net | Property and equipment are stated at historical cost less accumulated depreciation. Depreciation is calculated using the straight-line method over the estimated useful lives of the related assets as follows:
Costs incurred to improve leased office space are capitalized. Leasehold improvements are amortized on a straight-line basis over the shorter of the term of the lease or the estimated useful life of the improvement. Expenditures for major renewals and improvements that extend the useful lives of property and equipment are capitalized. Maintenance, repair costs and gains or losses associated with disposals are charged to expense as incurred. Product displays are deployed at retail locations. Because the product displays facilitate marketing of the Company’s products within the retail stores, depreciation for product displays is recorded in sales and marketing expenses in the consolidated statements of operations and comprehensive loss.
|
||||||||||||||||||||||||||||||||||||
| Cloud Computing Arrangements | The Company incurs costs to implement cloud computing arrangements that are hosted by a third-party vendor. For cloud computing arrangements that do not include a software license, implementation costs incurred during the application development stage are capitalized until the software is ready for its intended use. The costs are then amortized on a straight-line basis over the term of the associated hosting arrangement and are recognized as an operating expense within the consolidated statements of operations and comprehensive loss. Capitalized costs related to cloud computing arrangements, net of accumulated amortization, are reported as a component of other noncurrent assets on the Company's consolidated balance sheets. | ||||||||||||||||||||||||||||||||||||
| Impairment of Goodwill and Indefinite-lived Intangible Assets | Goodwill and indefinite-lived intangible assets are not amortized and are tested for impairment on an annual basis during the third quarter of each fiscal year or between annual tests if an event occurs or circumstances change that would more likely than not reduce the fair value of the reporting unit or asset below its carrying value. In connection with the Company's evaluation of goodwill impairment, the Company performs a qualitative assessment to determine if it is more likely than not that the fair value of a reporting unit is less than its carrying amount. If the qualitative assessment is not conclusive, the Company tests goodwill for impairment, including comparing the fair value of the reporting unit to its carrying value (including attributable goodwill). The Company determines fair value of its reporting unit using an income or market approach incorporating market participant considerations and management’s assumptions on revenue growth rates, operating margins, discount rates and expected capital expenditures. Fair value determinations may include both internal and third-party valuations. In connection with the Company’s evaluation of indefinite-lived intangible asset impairment, the Company performs a qualitative assessment to determine if it is more likely than not that the fair value of the asset is less than its carrying amount. If the qualitative assessment is not conclusive, the Company proceeds to test for impairment by comparing the fair value of the asset to the carrying value. Fair value is determined based on estimated discounted future cash flow analyses that include significant management assumptions such as revenue growth rates, weighted-average costs of capital and assumed royalty rates. If the carrying value exceeds fair value, an impairment charge will be recorded to reduce the asset to fair value.
|
||||||||||||||||||||||||||||||||||||
| Impairment of Long-Lived Assets | The Company evaluates the recoverability of its long-lived assets, which primarily comprises property and equipment and operating lease right-of-use assets, for impairment whenever events or changes in circumstances indicate that the carrying amounts may not be recoverable. The Company performs impairment testing at the level that represents the lowest level for which identifiable cash flows are largely independent of the cash flows of other assets and liabilities. Recoverability is measured by comparing the carrying amounts to the expected future undiscounted cash flows attributable to the assets. If it is determined that an asset may not be recoverable, an impairment loss equal to the excess of the asset’s carrying value over its fair value is recorded. Fair value is determined based on estimated discounted future cash flows analyses. There were no impairment charges identified on the Company's long-lived assets during fiscal years 2025, 2024, and 2023.
|
||||||||||||||||||||||||||||||||||||
| Product Warranties | The Company’s products are covered by warranty to be free from defects in material and workmanship for a period of one year, except in the EU and select other countries where the Company provides a minimum two-year warranty, depending on the region. At the time of sale, an estimate of future warranty costs is recorded as a component of cost of revenue and a warranty liability is recorded for estimated costs to satisfy the warranty obligation. The Company’s estimate of costs to fulfill its warranty obligations is based on historical experience and expectations of future costs to repair or replace.
|
||||||||||||||||||||||||||||||||||||
| Legal Contingencies | If a potential loss from any claim or legal proceeding is considered probable, and the amount can be reasonably estimated, the Company records a liability for an estimated loss. Legal fees are expensed as incurred and included in general and administrative expenses in the consolidated statements of operations and comprehensive loss. See Note 12. Commitments and Contingencies for additional information regarding legal contingencies.
|
||||||||||||||||||||||||||||||||||||
| Treasury Stock | The Company accounts for treasury stock acquisitions using the cost method. The Company accounts for the retirement of treasury stock by deducting its par value from common stock and reflecting any excess of cost over par value as a deduction from additional paid-in capital on the consolidated balance sheets.
|
||||||||||||||||||||||||||||||||||||
| Fair Value Accounting | Assets and liabilities recorded at fair value on the consolidated balance sheets are categorized based upon the level of judgment associated with the inputs used to measure their fair value. Fair value is estimated by applying the following hierarchy, which prioritizes the inputs used to measure fair value into three levels and bases the categorization within the hierarchy upon the lowest level of input that is available and significant to the fair value measurement:
|
||||||||||||||||||||||||||||||||||||
| Foreign Currency | Certain of the Company’s wholly owned subsidiaries have non-U.S. dollar functional currencies. The Company translates assets and liabilities of non-U.S. dollar functional currency subsidiaries into U.S. dollars using exchange rates in effect at the end of each period and stockholders’ equity at historical rates. Revenue and expenses for these subsidiaries are translated using rates that approximate those in effect during the period. Gains and losses from translation are recognized in foreign currency translation included in accumulated other comprehensive loss. The Company remeasures monetary assets or liabilities denominated in currencies other than the functional currency using exchange rates prevailing on the balance sheet date, and non-monetary assets and liabilities at historical rates. Foreign currency remeasurement and transaction gains and losses are included in other income (expense), net.
|
||||||||||||||||||||||||||||||||||||
| Revenue Recognition | Revenue is recognized upon transfer of control of promised products or services to customers in an amount that reflects the consideration the Company expects to receive in exchange for those products or services. Revenue is recognized net of allowances for returns, discounts, sales incentives, and any taxes collected from customers. The Company defers a portion of revenue that is allocated to unspecified software upgrades and cloud-based services, as well as for newly launched products sold to resellers not recognized until the date of general availability is reached. The Company's contracts generally include a combination of products and services. Revenue is allocated to distinct performance obligations and is recognized net of allowances for returns, discounts, sales incentives and any taxes collected from customers, which are subsequently remitted to governmental authorities. Shipping and handling costs associated with outbound freight after control over a product has transferred to a customer are not considered a separate performance obligation and are accounted for as a fulfillment cost and are included in cost of revenue. Nature of Products and Services Product revenue primarily includes sales of Sonos speakers and Sonos system products, which include software that enables the Company’s products to operate over a customer’s wireless network, as well as connect to various third-party services, including music and voice. The Company also generates a small portion of revenue from Partner products and other revenue sources in connection with partnerships, accessories, professional services, licensing, advertising, and subscription revenue. Revenue for module units is related to hardware and embedded software that is integrated into final products that are manufactured and sold by the Company's partners. Software primarily consists of firmware embedded in the products and the Sonos app, which is software that can be downloaded to consumer devices at no charge, with or without the purchase of one of the Company’s products. Products and related software are accounted for as a single performance obligation and all intended functionality is available to the customer upon purchase. The revenue allocated to the products and related software is the substantial portion of the total sale price. Product revenue is recognized at the point in time when control is transferred, which is either upon shipment or upon delivery to the customer, depending on delivery terms. Service revenue includes revenue allocated to (i) unspecified software upgrades and (ii) cloud-based services that enable products to access third-party music and voice assistant platforms, based on relative standalone selling price, which are each distinct performance obligations and are provided to customers at no additional charge. Unspecified software upgrades are provided on a when-and-if-available basis and have historically included updates and enhancements such as bug fixes, feature enhancements and updates to the ability to connect to third-party music or voice assistant platforms. Service revenue is recognized ratably over the estimated service period. Significant Judgments The Company’s contracts with customers generally contain promises to transfer products and services as described above. Determining whether products and services are considered distinct performance obligations that should be accounted for separately requires significant judgment. Determining the SSP for each distinct performance obligation requires judgment. The Company estimates SSP for items that are not sold separately, which include the products and related software, unspecified software upgrades and cloud-based services, using information that may include competitive pricing information, where available, as well as analyses of the cost of providing the products or services plus a reasonable margin. In developing SSP estimates, the Company also considers the nature of the products and services and the expected level of future services. Determining the revenue recognition period for unspecified software upgrades and cloud-based services also requires judgment. The Company recognizes revenue attributable to these performance obligations ratably over the best estimate of the period that the customer is expected to receive the services. In developing the estimated period of providing future services, the Company considers past history, plans to continue to provide services, including plans to continue to support updates and enhancements to prior versions of the Company’s products, expected technological developments, obsolescence, competition and other factors. The estimated service period may change in the future in response to competition, technology developments and the Company’s business strategy. The Company offers sales incentives through various programs consisting primarily of discounts, cooperative advertising and market development fund programs. The Company records cooperative advertising and market development fund programs with customers as a reduction to revenue unless it receives a distinct benefit in exchange for credits claimed by the customer and can reasonably estimate the fair value of the benefit received, in which case the Company records it as an expense. The Company recognizes a liability or a reduction to accounts receivable, and reduces revenue based on the estimated amount of sales incentives that will be claimed by customers. Estimates for sales incentives are developed using the most likely amount and are included in the transaction price to the extent that a significant reversal of revenue would not result once the uncertainty is resolved. In developing its estimate, the Company also considers the susceptibility of the incentive to outside influences, the length of time until the uncertainty is resolved and the Company’s experience with similar contracts. Reductions in revenue related to discounts are allocated to products and services on a relative basis based on their respective SSP. Judgment is required to determine the timing and amount of recognition of marketing funds which the Company estimates based on past practice of providing similar funds. The Company accepts returns from direct customers and from certain resellers. To establish an estimate for returns, the Company uses the expected value method by considering a portfolio of contracts with similar characteristics to calculate the historical returns rate. When determining the expected value of returns, the Company considers future business initiatives and relevant anticipated future events. Supplier Concentration The Company relies on third parties for the supply and manufacture of its products, as well as third-party logistics providers for the distribution of its products. In instances where these parties fail to perform their obligations, the Company may be unable to find alternative suppliers or satisfactorily deliver its products to customers on time, if at all. During fiscal years 2025, 2024 and 2023, approximately 53%, 60% and 58%, respectively, of the Company’s finished goods purchased during each year were from one vendor. Deferred Revenue and Payment Terms The Company invoices each order upon hardware shipment or delivery and recognizes revenue for each distinct performance obligation when transfer of control has occurred, which in the case of services, may extend over several reporting periods. Amounts invoiced in advance of revenue recognition are recorded as deferred revenue on the consolidated balance sheets. Deferred revenue primarily relates to revenue allocated to unspecified software upgrades and platform services, as well as for newly launched products sold to resellers not recognized until the date of general availability is reached. General availability deferrals are classified as current deferred revenue as the Company starts shipping the product to the reseller within one month prior to the general availability date. The Company classifies deferred revenue as noncurrent if amounts are expected to be recognized as revenue beyond one year from the balance sheet date. Payment Terms Payment terms and conditions vary among the Company’s distribution channels although terms generally include a requirement of payment within 30 days of product shipment. Sales directly to customers from the Company’s website are paid at the time of product shipment. Prior to providing payment terms to customers, an evaluation of the customer’s credit risk is performed. Contractual allowances are an offset to accounts receivable.

||||||||||||||||||||||||||||||||||||
| Research and Development | Research and development expenses consist primarily of personnel-related expenses, consulting and outside professional service costs, tooling and prototype materials and overhead costs. Substantially all of the Company’s research and development expenses are related to developing new products and services and improving existing products and services. To date, software development costs have been expensed as incurred because the period between achieving technological feasibility and the release of the software has been short and development costs qualifying for capitalization have been insignificant. In-process research and development ("IPRD") assets represent the fair value of incomplete research and development projects obtained as part of a business combination that have not yet reached technological feasibility and are initially not subject to amortization; rather, these assets are subject to impairment considerations of indefinite-lived intangible assets. Upon completion of development, IPRD assets are considered definite-lived intangible assets, transferred to developed technology and are amortized over their useful lives. If a project were to be abandoned, the IPRD would be considered fully impaired and expensed to research and development.
|
||||||||||||||||||||||||||||||||||||
| Advertising Costs | Advertising costs are expensed as incurred and included in sales and marketing expenses. | ||||||||||||||||||||||||||||||||||||
| Restructuring and Related Costs | Costs associated with a restructuring plan generally consist of involuntary employee termination benefits, contract termination costs, and other exit-related costs including costs to close facilities. The Company records a liability for involuntary employee termination benefits when management has committed to a plan that establishes the terms of the arrangement and that plan has been communicated to employees. Costs to terminate a contract before the end of the term are recognized on the termination date, and costs that will continue to be incurred in a contract for the remaining term without economic benefit are recognized as of the cease-use date. Restructuring and related costs may also include the write-down of related assets, including operating lease right-of-use assets, when the sale or abandonment of the asset is a direct result of the plan. Other exit-related costs are recognized as incurred. Restructuring and related costs are recognized as within operating expenses and cost of revenue within the consolidated statements of operations and comprehensive loss and are classified based on the Company's classification policy for each category of operating expense. | ||||||||||||||||||||||||||||||||||||
| Stock-Based Compensation | The Company measures stock-based compensation cost at fair value on the date of grant. Compensation cost for stock options is recognized, on a straight-line basis, as an expense over the period of vesting as the employee performs the related services, net of estimated forfeitures. The Company estimates the fair value of stock option awards using the Black-Scholes option-pricing model and is based on the Company’s closing stock price on the trading day immediately prior to the date of grant. The Company estimates forfeitures based on expected future terminations and will revise rates, as necessary, in subsequent periods if actual forfeitures differ from initial estimates. The fair value of RSUs is based on the Company's closing stock price on the trading day immediately preceding the date of grant. The Company estimates the fair value of performance stock units ("PSU") on the grant date and recognizes compensation expense in the period it becomes probable that performance conditions will be achieved. On a quarterly basis, the Company re-evaluates the assumption of the probability that performance conditions will be satisfied and revises its estimates as appropriate as new or updated information becomes available.
|
||||||||||||||||||||||||||||||||||||
| Retirement Plans | The Company has a defined contribution 401(k) plan (the "401(k) Plan") for the Company’s U.S.-based employees, as well as various defined contribution plans for its international employees. Eligible U.S. employees may make tax-deferred contributions under the 401(k) plan, but are limited to the maximum annual dollar amount allowable under the Internal Revenue Code of 1986, as amended (the "Code"). The Company matches contributions towards the 401(k) Plan and international defined contribution plans. | ||||||||||||||||||||||||||||||||||||
| Income Taxes | The Company accounts for income taxes under the asset and liability method, which requires the recognition of deferred tax assets and liabilities for the expected future tax consequences of events that have been included in the consolidated financial statements. Under this method, deferred tax assets and liabilities are determined based on 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 differences are expected to reverse. The effect of a change in tax rates on deferred tax assets and liabilities is recognized in income during the period that includes the enactment date. The Company records a valuation allowance when necessary to reduce its deferred tax assets to amounts that are more likely than not to be realized. In making such a determination, all available positive and negative evidence is considered, including future reversals of existing taxable temporary differences, projected future taxable income, tax-planning strategies, and results of recent operations. If the Company determines that it would be able to realize its deferred tax assets in the future in excess of their net recorded amount, the Company would make an adjustment to the deferred tax asset valuation allowance, which would result in a benefit to income taxes. The Company records uncertain tax positions in accordance with a two-step process whereby (i) the Company determines whether it is more likely than not that the tax positions will be sustained on the basis of the technical merits of the position and (ii) for those tax positions that meet the more likely than not recognition threshold, the Company recognizes the largest amount of tax benefit that is more than 50% likely to be realized upon ultimate settlement with the related tax authority. The Company includes interest and penalties related to unrecognized tax benefits within the provision for income taxes in the consolidated statements of operations and comprehensive loss. The Company has not incurred any interest or penalties related to unrecognized tax benefits in any of the periods presented. The Company’s provision for (benefit from) income taxes, deferred tax assets and liabilities, and liabilities for unrecognized tax benefits involves the use of estimates, assumptions and judgments. Although the Company believes its estimates, assumptions and judgments to be reasonable, any changes in tax law or its interpretation of tax laws and the resolutions of potential tax audits could significantly impact the amounts provided for income taxes in the Company’s consolidated financial statements. Actual future operating results and the underlying amount and type of income could differ materially from the Company’s estimates, assumptions and judgments thereby impacting the Company’s financial position and results of operations.
|
||||||||||||||||||||||||||||||||||||
| Segment Information | The Company operates as one operating segment as it only reports aggregate financial information on a consolidated basis, accompanied by disaggregated information about revenue by geographic region and product category, to its Chief Executive Officer, who is the Company’s Chief Operating Decision Maker ("CODM"). The CODM reviews financial information on a consolidated basis for purposes of making operating decisions, allocating resources, and evaluating financial performance. The CODM uses consolidated net income (loss) to measure segment profit or loss and make key operating decisions, such as allocation of the budget and monitoring budget versus actual results. Significant expenses within net income (loss) include cost of revenue, research and development, sales and marketing, and general and administrative, which are each separately presented on the Company’s consolidated statements of operations and comprehensive loss. Other segment items include interest income, interest expense, other income (expense), and provision for income taxes, which are also each separately presented on the Company’s consolidated statements of operations and comprehensive loss. The CODM does not evaluate segment performance or allocate resources using asset information.
|
||||||||||||||||||||||||||||||||||||
| Leases | The majority of the Company’s leases are for its office spaces and facilities, which are accounted for as operating leases. The Company leases office space in California, as well as offices in various locations in the U.S., with additional sales, operations, and research and development offices around the world. The Company determines whether an arrangement is a lease at inception if there is an identified asset, and if it has the right to control the identified asset for a period of time. Some of the Company’s leases include options to extend the leases for up to 5 years, and some include options to terminate the leases. The Company's lease terms are only for periods in which it has enforceable rights and are impacted by options to extend or terminate the lease only when it is reasonably certain that the Company will exercise the option. For leases with terms greater than 12 months, the Company records the related right-of-use asset and lease obligation at the present value of lease payments over the lease terms. Leases with an initial term of 12 months or less are not recorded on the balance sheet. Lease expense is recognized on a straight-line basis over the lease term. The Company's leases do not include any residual value guarantees or bargain purchase options. Lease agreements will typically exist with lease and non-lease components, which are accounted for separately. The Company's agreements may contain variable lease payments. The Company includes variable lease payments that depend on an index or a rate and exclude those which depend on facts or circumstances occurring after the commencement date, other than the passage of time. As most of the Company’s leases do not contain an implicit interest rate, the Company uses judgment to determine an incremental borrowing rate, which is defined as the rate of interest the Company would have to pay to borrow an amount that is equal to the lease obligations, on a collateralized basis, and over a similar term. The Company takes into consideration the terms of the Company's Credit Facility (as defined in Note 7. Debt), lease terms, and current interest rates to determine the incremental borrowing rate at lease commencement date. At September 27, 2025, the Company's weighted-average discount rate was 5.51%, while the weighted-average remaining lease term was 8.6 years. As part of the supplemental cash flow disclosure, the right-of-use assets obtained in exchange for new operating lease liabilities does not reflect the impact of prepaid or deferred rent.

| Recently adopted accounting pronouncements | In November 2023, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update (“ASU”) No. 2023-07, Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures. This standard expands public entities’ segment disclosures by requiring disclosure of significant segment expenses that are regularly provided to the chief operating decision maker and included within each reported measure of segment profit or loss, an amount and description of its composition for other segment items, and interim disclosures of a reportable segment’s profit or loss and assets. All disclosure requirements under ASU 2023-07 are also required for public entities with a single reportable segment. The Company adopted this standard in the fourth quarter of fiscal 2025. Refer to our significant accounting policies above for the impact of adoption. Recent accounting pronouncements pending adoption In September 2025, the FASB issued ASU No. 2025-06, Intangibles — Goodwill and Other — Internal-Use Software (Subtopic 350-40): Targeted Improvements to the Accounting for Internal-Use Software. The amendments in this update modernize the recognition and capitalization framework to reflect current software development practices, including iterative and agile methodologies, by removing references to "development stages". It also clarifies the criteria for capitalization, which begins when both of the following occur: (1) management has authorized and committed to funding the software project and (2) it is probable that the project will be completed and the software will be used to perform the function intended. The amendments are effective for fiscal years beginning after December 15, 2027, and interim periods within those annual reporting periods, with early adoption permitted. The amendments in this update may be applied utilizing a prospective transition approach, a retrospective transition approach, or a modified transition approach that is based on the status of the project and whether software costs were capitalized before the date of adoption. The Company is currently evaluating the pronouncement to determine the impact it may have on the Company's consolidated financial statements and related disclosures. In July 2025, the FASB issued ASU No. 2025-05, Financial Instruments — Credit Losses (Topic 326): Measurement of Credit Losses for Accounts Receivable and Contract Assets. The amendments in this update provide a practical expedient for the application of the current expected credit losses model to current accounts receivable and contract assets. The amendments are effective for fiscal years beginning after December 15, 2025, with early adoption permitted. The transition method is prospective. The Company is currently evaluating the pronouncement to determine the impact it may have on the Company's consolidated financial statements and related disclosures. 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. This standard requires disclosure of disaggregated information about significant expenses within relevant income statement captions, such as purchases of inventory, employee compensation, depreciation, and amortization. Also required is a qualitative description of the amounts remaining in relevant expense captions that are not separately disaggregated. In January 2025, the FASB issued ASU 2025-01, Income Statement — Reporting Comprehensive Income — Expense Disaggregation Disclosures (Subtopic 220-40): Clarifying the Effective Date, which clarifies that the amendments in ASU 2024-03 are effective for fiscal years beginning after December 15, 2026, and interim periods within annual reporting periods beginning after December 15, 2027. The amendments may be applied retrospectively or prospectively, with early adoption permitted. The Company is currently evaluating the pronouncement to determine the impact it may have on the Company's consolidated financial statements and related disclosures. In December 2023, the FASB issued ASU No. 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures. This update includes amendments that further enhance income tax disclosures, primarily through standardization and disaggregation of rate reconciliation categories and income taxes paid by jurisdiction. The amendments are effective for fiscal years beginning after December 15, 2024, with early adoption permitted, and may be applied either prospectively or retrospectively. The Company is currently evaluating the pronouncement to determine the impact it may have on the Company's consolidated financial statements and related disclosures.
