Business Overview and Basis of Presentation	1. Business Overview and Basis of Presentation Description of business Sonos, Inc. and its wholly owned subsidiaries (collectively, "Sonos," the "Company," "we," "us" or "our") designs, develops, manufactures, and sells audio products and services. The Sonos sound system provides customers with an immersive listening experience created by the design of its speakers, headphones and components, a proprietary software platform, and the ability to stream content from a variety of sources over the customer’s wireless network or over Bluetooth. The Company’s products are sold through third-party physical retailers, including custom installers of home audio systems, select e-commerce retailers, and its website, sonos.com. The Company’s products are distributed in over 60 countries through its wholly owned subsidiaries: Sonos Europe B.V. in the Netherlands, Beijing Sonos Technology Co. Ltd. in China, Sonos Japan GK in Japan, and Sonos Australia Pty Ltd. in Australia. Basis of presentation and preparation The accompanying condensed consolidated financial statements are unaudited. The condensed consolidated balance sheet as of September 28, 2024, has been derived from the audited consolidated financial statements of the Company. The accompanying condensed consolidated financial statements have been prepared in accordance with generally accepted accounting principles in the United States of America ("U.S. GAAP") for interim financial information and the applicable rules and regulations of the Securities and Exchange Commission ("SEC"). Accordingly, they do not include all the information and footnotes required by U.S. GAAP for annual financial statements. They should be read in conjunction with the consolidated financial statements and notes thereto contained in the Company’s Annual Report on Form 10-K for the fiscal year ended September 28, 2024, (the "Annual Report"), filed with the SEC on November 15, 2024. In management’s opinion, the accompanying unaudited condensed consolidated financial statements include all adjustments, consisting of only normal recurring adjustments, necessary for the fair statement of the Company’s financial position, its results of operations, and its cash flows for the interim periods presented. The results of operations for the three months ended December 28, 2024, are not necessarily indicative of the results to be expected for the full fiscal year or any other 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 fourth quarter of the Company’s fiscal year ended October 3, 2020, and will reoccur in the fiscal year ending October 3, 2026. The three months ended December 28, 2024 and December 30, 2023, spanned 13 weeks each. As used in this Quarterly Report on Form 10-Q, "fiscal 2025" refers to the fiscal year ending September 27, 2025, "fiscal 2024" refers to the fiscal year ended September 28, 2024, and "fiscal 2023" refers to the fiscal year ended 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 condensed consolidated financial statements and accompanying notes. Actual results could differ materially from those estimates. On an ongoing basis, the Company evaluates its estimates and judgments compared to historical experience and expected trends.

Fair Value Disclosures [Abstract]
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 Company utilizes the following fair value hierarchy to establish priorities of the inputs used to measure fair value: • Level 1: Quoted prices in active markets for identical assets or liabilities. • Level 2: Observable inputs other than quoted market prices included in Level 1, such as quoted prices for similar assets or liabilities in markets that are not active; or other inputs that are observable or can be corroborated by observable market data. The following table summarizes cash, cash equivalents and marketable securities by investment category as of December 28, 2024 and September 28, 2024: December 28, 2024 Amortized Cost Unrealized Gain Unrealized Loss Estimated Fair Value Cash and Cash Equivalents Marketable Securities Cash $ 234,980 $ — $ — $ 234,980 $ 234,980 $ — Level 1: Money market funds 40,881 — — 40,881 40,881 — Subtotal 40,881 — — 40,881 40,881 — Level 2: U.S. Treasury securities 51,959 50 (13) 51,996 4,094 47,902 Subtotal 51,959 50 (13) 51,996 4,094 47,902 Total $ 327,820 $ 50 $ (13) $ 327,857 $ 279,955 $ 47,902 September 28, 2024 Amortized Cost Unrealized Gain Unrealized Loss Estimated Fair Value Cash and Cash Equivalents Marketable Securities Cash $ 144,184 $ — $ — $ 144,184 $ 144,184 $ — Level 1: Money market funds 25,548 — — 25,548 25,548 — Subtotal 25,548 — — 25,548 25,548 — Level 2: U.S. Treasury securities 51,304 122 — 51,426 — 51,426 Subtotal 51,304 122 — 51,426 — 51,426 Total $ 221,036 $ 122 $ — $ 221,158 $ 169,732 $ 51,426 Marketable securities As of December 28, 2024, the Company held no securities with original maturities exceeding one year. Realized gains and losses on the sale of securities are recorded in other income (expense), net in the condensed consolidated statements of operations and comprehensive income. There were no realized gains or losses on sales of marketable securities during the three months ended December 28, 2024. 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. Accordingly, an allowance for credit losses was deemed unnecessary for these securities as of December 28, 2024. Accrued interest receivable related to our marketable securities was immaterial as of December 28, 2024. No accrued interest receivables were written off during the three months ended December 28, 2024.

Debt	6. Debt On October 13, 2021, the Company entered into a Revolving Credit Agreement with JPMorgan Chase Bank, N.A., as the administrative agent, and Bank of America N.A., Morgan Stanley Senior Funding, Inc., and Goldman Sachs Bank USA as the other lenders party thereto (the "Revolving Credit Agreement"). The Revolving Credit Agreement provides for (i) a five-year senior secured revolving credit facility in the amount of up to $100.0 million and (ii) an uncommitted incremental facility subject to certain conditions. Proceeds are to be used for working capital and general corporate purposes. In June 2023, the Company amended the Revolving Credit Agreement, replacing prior references to LIBOR with references to SOFR as a result of the discontinuation of LIBOR. The facility may be drawn as an Alternative Base Rate Loan (at 1.00% plus an applicable margin) or Term Benchmark Loan (at the Term SOFR Rate, plus the applicable Term SOFR Adjustment ranging from 0.11% to 0.43%, plus an applicable margin (in total, "Adjusted Term SOFR")). The Company must also pay (i) an unused commitment fee ranging from 0.200% to 0.275% per annum of the average daily unused portion of the aggregate revolving credit commitment under the agreement and (ii) a per annum fee equal to the applicable margin over Adjusted Term SOFR multiplied by the aggregate face amount of outstanding letters of credit. As of December 28, 2024, the Company did not have any outstanding borrowings and had $2.4 million in undrawn letters of credit that reduce the availability under the Revolving Credit Agreement. The Company’s obligations under the Revolving Credit Agreement are secured by substantially all of the Company’s assets. The Revolving Credit Agreement contains customary representations and warranties, customary affirmative and negative covenants, a financial covenant that is tested quarterly and requires the Company to maintain a certain consolidated leverage ratio, and customary events of default. As of December 28, 2024, the Company was in compliance with all financial covenants under the Revolving Credit Agreement.

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	7. Commitments and Contingencies Commitments to suppliers As of December 28, 2024, the Company's open purchase orders to contract manufacturers for finished goods were approximately $84 million, the majority of which are expected to be paid over the next six months. As of December 28, 2024, the Company's expected commitments to suppliers for components were in the range of $170 million to $190 million, the majority of which is expected to be paid and/or utilized by our contract manufacturers in building finished goods within the next two years. 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 a panel of the appeals court. Google's petition for rehearing by the full appeals court has been denied. The stay in the counterpart lawsuit has been lifted. 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. The Company is appealing the ruling. 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. 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. The ITC has terminated the investigation as to one Google patent as a result of imminent expiration of that Google patent. The first ITC investigation concluded in December 2023 with a final determination of no violation by the Company. Google chose not to appeal this determination. The oral hearing in the second ITC investigation has been postponed after the administrative law judge has indicated that she will be invalidating both Google patents at issue. 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 by mid-2025. A range of loss, if any, associated with this matter is not probable or reasonably estimable as of December 28, 2024.

Income Taxes

Income Taxes	3 Months Ended

Income Tax Disclosure [Abstract]
Income Taxes	10. Income Taxes The Company’s income tax provision and the resulting effective tax rate for interim periods is generally determined based upon its estimated annual effective tax rate ("AETR"), adjusted for the effect of discrete items arising in that quarter. The impact of such inclusions could result in a higher or lower effective tax rate during a quarter, based upon the mix and timing of actual earnings or losses versus annual projections. In each quarter, the Company updates its estimate of the AETR, and if the estimated AETR changes, a cumulative adjustment is made in that quarter. The Company recorded a benefit from income taxes of $6.4 million and a provision for income taxes of $12.0 million for the three months ended December 28, 2024 and December 30, 2023, respectively, related to U.S. and non-U.S. income taxes. The negative U.S. AETR is driven by anticipated income tax expense on a forecasted U.S. book loss resulting from capitalizing research and development expense pursuant to U.S. Internal Revenue Code ("Section 174") with no corresponding deferred tax benefit. For the three months ended December 28, 2024, the Company utilized the AETR method to calculate separate U.S. and foreign income tax provisions. Separate U.S. and foreign AETRs were calculated in accordance with US GAAP since Sonos Inc is forecasted in a full-year loss with no corresponding deferred tax benefit while all non-U.S. entities are forecasted to profitability and, unlike the prior year, small fluctuations in forecasted pre-tax income (loss) are not expected to have a material impact on the estimated U.S. AETR. For the three months ended December 30, 2023, the Company calculated its U.S. income tax provision using the discrete method as though the interim period was an annual period since minor deviations in the projected pre-tax net income (loss) in the U.S. could have resulted in a disproportionate and unreliable effective tax rate under the AETR method. For the three months ended December 28, 2024, the Company’s tax benefit resulted from the application of a negative U.S. AETR to year-to-date U.S. pretax income offset in part by a tax provision for non-U.S. income taxes. For the three months ended December 30, 2023, the Company's U.S. income tax provision was adversely impacted by 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. For the three months ended December 28, 2024, the Company concluded that a full valuation allowance on its deferred tax assets in the U.S. continued to be appropriate considering cumulative pre-tax losses in recent years and uncertainty with respect to future taxable income. Release of the valuation allowance in the U.S. would result in a benefit to the income tax provision in 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 U.S.

Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of presentation and preparation	The accompanying condensed consolidated financial statements are unaudited. The condensed consolidated balance sheet as of September 28, 2024, has been derived from the audited consolidated financial statements of the Company. The accompanying condensed consolidated financial statements have been prepared in accordance with generally accepted accounting principles in the United States of America ("U.S. GAAP") for interim financial information and the applicable rules and regulations of the Securities and Exchange Commission ("SEC"). Accordingly, they do not include all the information and footnotes required by U.S. GAAP for annual financial statements. They should be read in conjunction with the consolidated financial statements and notes thereto contained in the Company’s Annual Report on Form 10-K for the fiscal year ended September 28, 2024, (the "Annual Report"), filed with the SEC on November 15, 2024. In management’s opinion, the accompanying unaudited condensed consolidated financial statements include all adjustments, consisting of only normal recurring adjustments, necessary for the fair statement of the Company’s financial position, its results of operations, and its cash flows for the interim periods presented. The results of operations for the three months ended December 28, 2024, are not necessarily indicative of the results to be expected for the full fiscal year or any other 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 fourth quarter of the Company’s fiscal year ended October 3, 2020, and will reoccur in the fiscal year ending October 3, 2026. The three months ended December 28, 2024 and December 30, 2023, spanned 13 weeks each. As used in this Quarterly Report on Form 10-Q, "fiscal 2025" refers to the fiscal year ending September 27, 2025, "fiscal 2024" refers to the fiscal year ended September 28, 2024, and "fiscal 2023" refers to the fiscal year ended 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 condensed consolidated financial statements and accompanying notes. Actual results could differ materially from those estimates. On an ongoing basis, the Company evaluates its estimates and judgments compared to historical experience and expected trends.
Recent accounting pronouncements pending adoption	In November 2024, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“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. The amendments are effective for fiscal years beginning after December 15, 2026, and interim periods beginning after December 15, 2027, with early adoption permitted. The amendments may be applied retrospectively or prospectively. The Company is currently evaluating the pronouncement to determine the impact it may have on the Company's consolidated financial statements and related disclosures.
