Sonos Inc,
Fiscal Year 2024.

Cash Flows Fiscal 2024 Changes in Cash Flows The following table summarizes our cash flows for the periods indicated: Fiscal Year Ended (In thousands)September 28, 2024September 30, 2023

Cash Flows from Investing Activities Cash used in investing activities of $105.2 million for fiscal 2024, primarily consisted of the purchases of marketable securities of $90.5 million, and purchases of property and equipment of $55.2 million mainly related to point-of-sale product displays, manufacturing-related tooling and test equipment to support the launch of new products, and leasehold improvements, partially offset by cash provided by maturities of marketable securities of $40.5 million.

Table of contents Item 7. Management's Discussion and Analysis of Financial Condition and Results of Operations The following discussion of our financial condition and results of operations should be read in conjunction with the consolidated financial statements and the notes thereto included elsewhere in this Annual Report on Form 10-K. The following discussion contains forward-looking statements that reflect our plans, estimates and beliefs. Our actual results could differ materially from those discussed in the forward-looking statements. Factors that could cause or contribute to these differences include those discussed below and elsewhere in this Annual Report on Form 10-K, particularly in the section titled "Risk Factors." We operate on a 52-week or 53-week fiscal year ending on the Saturday nearest September 30 each year. Our 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. References to fiscal 2024 are to our 52-week fiscal year ended September 28, 2024, references to fiscal 2023 are to our 52-week fiscal year ended September 30, 2023, references to fiscal 2022 are to our 52-week fiscal year ended October 1, 2022 and references to fiscal 2021 are to our 52-week fiscal year ended October 2, 2021.

Key Metrics In addition to the measures presented in our consolidated financial statements, we use the following key metrics to evaluate our business, measure our performance, identify trends affecting our business and assist us in making operational and strategic decisions. Our key metrics are total revenue, products sold, Adjusted EBITDA and Adjusted EBITDA margin. The most directly comparable financial measure calculated under U.S. GAAP for Adjusted EBITDA and Adjusted EBITDA margin are net income (loss) and net income (loss) margin, respectively.

The following table presents a reconciliation of net income (loss) to adjusted EBITDA: Fiscal Year Ended September 28,2024September 30,2023October 1,2022

Liquidity and Capital Resources Our operations are financed primarily through cash flows from operating activities. As of September 28, 2024, our principal sources of liquidity consisted of cash flows from operating activities, cash and cash equivalents of $169.7 million, including $36.4 million held by our foreign subsidiaries, marketable securities of $51.4 million, proceeds from the exercise of stock options, and borrowing capacity under the Credit Facility. In accordance with our policy, the undistributed earnings of our non-U.S. subsidiaries remain indefinitely reinvested outside of the United States as of September 28, 2024, as they are required to fund needs outside of the United States. In the event funds from foreign operations are needed to fund operations in the United States and if U.S. tax has not already been previously provided, we may be required to accrue and pay additional U.S. taxes to repatriate these funds. We believe our existing cash and cash equivalent balances, cash flows from operations, and committed credit lines will be sufficient to meet our long-term working capital and capital expenditure needs for at least the next 12 months. We hold our cash with a diverse group of major financial institutions and have processes and safeguards in place to manage our cash balances and mitigate the risk of loss. In October 2021, we entered into the Revolving Credit Agreement, which allows us to borrow up to $100 million, with a maturity date of October 2026. Our future capital requirements may vary materially from those currently planned and will depend on many factors, including our rate of revenue growth, the timing and extent of spending on research and development efforts and other business initiatives, our planned sales and marketing activities, the timing of new product introductions, our potential merger and acquisition activity, market acceptance of our products, and overall economic conditions. To the extent that current and anticipated sources of liquidity are insufficient to fund our future business activities and requirements, we may be required to seek additional equity or debt financing. The sale of additional equity would result in increased dilution to our stockholders. If we were to incur 31 additional debt financing it would result in increased debt service obligations and the instruments governing such debt could require additional operating and financing covenants that would restrict our operations.

Debt Obligations On October 13, 2021, we entered into 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 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, we amended our Revolving Credit Agreement to change the reference rate from LIBOR to the Secured Overnight Financing Rate ("SOFR"), effective July 1, 2023. The facility may be drawn as an Alternative Base Rate Loan (at 1.00% plus an applicable margin) or Term Benchmark Loan (SOFR plus an applicable margin). We 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 SOFR multiplied by the aggregate face amount of outstanding letters of credit. As of September 28, 2024, we did not have any outstanding borrowings and $1.8 million in undrawn letters of credit that reduce the availability under the Revolving Credit Agreement. Our obligations under the Revolving Credit Agreement are secured by substantially all of our assets. The Revolving Credit Agreement contains customary representations and warranties, customary affirmative and negative covenants, a financial covenant that is tested quarterly and requires us to maintain a certain consolidated leverage ratio, and customary events of default. As of September 28, 2024, we were in compliance with all financial covenants under the Revolving Credit Agreement.

Cash Flows from Financing Activities Cash used in financing activities of $137.3 million for fiscal 2024, primarily consisted of payments for repurchase of common stock of $129.0 million and payments for repurchase of common stock related to shares withheld for tax in connection with vesting of stock awards of $25.3 million, partially offset by proceeds from the exercise of options of $17.1 million. 32

Fiscal 2023 Changes in Cash Flows For the comparison of fiscal 2023 to fiscal 2022, refer to Part II, Item 7 "Management's discussion and analysis of financial condition and results of operations" of our Form 10-K for our fiscal year ended September 30, 2023, filed with the SEC on November 20, 2023, under the subheading "Liquidity and capital resources."

Contractual obligations See Note 7. Leases and Note 13. Commitments and Contingencies of the notes to our consolidated financial statements included elsewhere in this Annual Report on Form 10-K for further details.

Critical Accounting Policies and Estimates Our consolidated financial statements are prepared in accordance with U.S. GAAP. The preparation of these consolidated financial statements requires us to make estimates and assumptions that affect the reported amounts of assets, liabilities, revenue, expenses and related disclosures. We evaluate our estimates and assumptions on an ongoing basis. Our estimates are based on historical experience and various other assumptions that we believe to be reasonable under the circumstances. Actual results could differ materially from those estimates. Our critical accounting policies requiring estimates, assumptions and judgments that we believe have the most significant impact on our consolidated financial statements are described below.

Revenue Nature of Products and Services We generate substantially all of our revenue from the sale of Sonos speakers and Sonos system products. We also generate a portion of revenue from partner products and other revenue sources, such as architectural speakers from our Sonance partnership, and accessories such as speaker stands and wall mounts, as well as professional services, advertising revenue, licensing and subscription revenue such as Sonos Radio HD and Sonos Pro (software-as-a-service). Our contracts generally include a combination of products and related software, and services. Products and related software primarily constitute Sonos speakers and Sonos system products and include software that enables our products to operate over a customer's wireless network as well as connect to various third-party services, including music and voice. Additionally, module revenue includes hardware and embedded software that is integrated into final products that are manufactured and sold by our partners. 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. Unspecified software upgrades 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.

Performance Obligations Determining whether products and services are considered distinct performance obligations that should be accounted for separately requires significant judgment. We have determined that products and related software represent a single performance obligation. The basis of our determination is these products are highly dependent on, and interrelated with, the embedded software and cannot function as they are intended without the software. We determined that unspecified software upgrades represent a separate performance obligation as they occur subsequent to the time of purchase, fulfillment of these promises can be made separately, there are no resulting significant modification or customization to our products, and these services are provided to customers at no additional charge. We have also determined cloud-based services to be a separate performance obligation based as they are additive to our products rather than transformative.

Revenue We generate substantially all of our revenue from the sale of Sonos speakers and Sonos system products. We also generate a portion of revenue from Partner products and other revenue sources, such as architectural speakers from our Sonance partnership, accessories such as speaker stands and wall mounts, professional services, licensing, and advertising revenue.

Transaction price Revenue is recognized at transaction price which is the amount that we expect to receive in exchange for our products and services. Transaction price is calculated as the stated consideration net of variable consideration such as allowances for returns, discounts, sales incentives, and any tax collected from customers. The transaction price is allocated to the separate performance obligations in the contract based on relative standalone selling prices ("SSPs"). We estimate SSP for items that are not sold separately, which include the products and related software, unspecified software upgrades and cloud services, using information that may include competitive pricing information, where available, as well as analysis of the cost of providing the products or services plus a reasonable margin. In developing SSP estimates, we also consider the nature of the products and services and the expected level of future services. We offer sales incentives through various programs, consisting primarily of discounts, cooperative advertising and market development fund programs. Reductions in revenue related to discounts are allocated to products and services on a relative basis based on their respective SSP. Estimates for sales incentives are developed using the most likely amount based on our past experience with 33 similar contracts and are included in the transaction price to the extent that a significant reversal of revenue would not result once the uncertainty is resolved. We accept returns from direct customers and from certain resellers. To establish an estimate for returns, we use the expected value method by considering a portfolio of contracts with similar characteristics to calculate the historical returns rate. A change in contract, future business initiatives, or customer behavior due to macroeconomic conditions could require us to change the above estimates, or if actual results differ significantly from the estimates, we would be required to increase or reduce revenue to reflect the impact.

Revenue Recognition Revenue is allocated to products and related software, and to unspecified software upgrades and cloud-based services. Revenue allocated to the products and related software is the substantial portion of the total sale price. Revenue for products and related software is recognized at the point in time when control is transferred to the customer, which is either upon shipment or upon delivery to the customer, depending on delivery terms. Revenue allocated to unspecified software upgrades and cloud-based services is deferred and recognized ratably over our best estimate of the period that the customer is expected to receive the services. Determining the revenue recognition period for unspecified software upgrades and cloud services requires judgment. In developing the estimated period of providing future services, we consider our past history, our plans to continue to provide services, including plans to continue to support updates and enhancements to prior versions of our 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 our business strategy. For fiscal 2024, there has not been any event that would require us to materially change the underlying assumptions of revenue estimates. A hypothetical 10% change to our SSP estimates and/or the estimated recognition period for unspecified software upgrades and cloud-based services, would not result in a material change to our fiscal 2024 revenue.

Income Taxes Our income tax expense, deferred tax assets and liabilities, and liabilities for unrecognized tax benefits reflect our best estimate of current and future taxes to be paid. Significant judgments and estimates are required in the determination of the consolidated income tax expense. We prepare and file income tax returns based on our interpretation of each jurisdiction's tax laws and regulations. In preparing our consolidated financial statements, we estimate our income tax liability in each of the jurisdictions in which we operate by estimating our actual current tax expense together with assessing temporary differences resulting from differing treatment of items for tax and financial reporting purposes. These differences result in deferred tax assets and liabilities, which are included in our consolidated balance sheets. Significant management judgment is required in assessing the realizability of our deferred tax assets. In performing this assessment, we consider whether it is "more-likely-than-not" that some portion or all the deferred tax assets will not be realized. The ultimate realization of deferred tax assets is dependent upon the generation of future taxable income during the periods in which those temporary differences become deductible. In making this determination, we consider the scheduled reversal of deferred tax liabilities, projected future taxable income and the effects of tax planning strategies. We recorded a valuation allowance against all our U.S. deferred tax assets as of September 28, 2024. We intend to continue maintaining a full valuation allowance on our U.S. deferred tax assets until there is sufficient evidence to support the reversal of all or some portion of these allowances. We account for uncertain tax positions using a "more-likely-than-not" threshold for recognizing and resolving uncertain tax positions. We evaluate uncertain tax positions on a quarterly basis and consider various factors, that include, but are not limited to, changes in tax law, the measurement of tax positions taken or expected to be taken in tax returns, the effective settlement of matters subject to audit, information obtained during in process audit activities and changes in facts or circumstances related to a tax position. We accrue for potential interest and penalties related to unrecognized tax benefits in income tax expense. Changes in the recognition 34 or measurement of uncertain tax positions could result in material increases or decreases in our income tax expense in the period in which we make the change, which could have a material impact on our effective tax rate and operating results. Our policy with respect to the undistributed earnings of our non-U.S. subsidiaries is to maintain an indefinite reinvestment assertion as they are required to fund needs outside of the United States. This assertion is made on a jurisdiction by jurisdiction basis and takes into account the liquidity requirements in both the United States and of our foreign subsidiaries.

For a description of our revenue recognition policies, see the section titled "Critical accounting policies and estimates." Products Sold Products sold represents the number of products that are sold during a period, net of returns and includes the sale of products in the Sonos speakers and Sonos system products categories, as well as module units sold through our Partner products and other revenue category. Growth rates between products sold and revenue are not perfectly correlated because our revenue is affected by other variables, such as the mix of products sold during the period, promotional discount activity, the introduction of new products that may have higher or lower than average selling prices, as well as the impact of recognition of previously deferred revenue.

Adjusted EBITDA and Adjusted EBITDA Margin We define Adjusted EBITDA as net income (loss) adjusted to exclude the impact of stock-based compensation expense, depreciation and amortization, interest, other income (expense), taxes, and other items that we do not consider representative of our underlying operating performance. We define Adjusted EBITDA margin as Adjusted EBITDA divided by revenue. See the section titled "Results of Operations -Non-GAAP Financial Measures" for information regarding our use of Adjusted EBITDA and Adjusted EBITDA margin, and a reconciliation of net income (loss) to Adjusted EBITDA and net income (loss) margin to Adjusted EBITDA margin.

Non-GAAP Financial Measures To supplement our consolidated financial statements presented in accordance with U.S. GAAP, we monitor and consider Adjusted EBITDA, Adjusted EBITDA margin, and constant currency which are non-GAAP financial measures. These non-GAAP financial measures are not based on any standardized methodology prescribed by U.S. GAAP and are not necessarily comparable to similarly titled measures presented by other companies. We define Adjusted EBITDA as net income (loss) adjusted to exclude the impact of depreciation and amortization, stock-based compensation expense, interest income, interest expense, other income (expense), income taxes, legal and transaction related costs, restructuring and abandonment costs, and other items that we do not consider representative of underlying operating performance. We define Adjusted EBITDA margin as Adjusted EBITDA divided by revenue. We also present percentage sales growth in constant currency to show performance unaffected by fluctuations in currency exchange rates. We calculate constant currency growth percentages by translating our current period financial results using the prior period average currency exchange rates and comparing these amounts to our prior period reported results. We use these non-GAAP financial measures to evaluate our operating performance and trends and make planning decisions. We believe that these non-GAAP financial measures help identify underlying trends in our business that could otherwise be masked by the effect of the expenses and other items that we exclude in these non-GAAP financial measures. Accordingly, we believe that these non-GAAP financial measures provide useful information to investors and others in understanding and evaluating our operating results, enhancing the overall understanding of our past performance and future prospects, and allowing for greater transparency with respect to a key financial metric used by our management in its financial and operational decision-making. Adjusted EBITDA and Adjusted EBITDA margin are non-GAAP financial measures, and should not be considered in isolation of, or as an alternative to, measures prepared in accordance with U.S. GAAP. There are a number of limitations related to the use of Adjusted EBITDA rather than net income (loss), which is the nearest U.S. GAAP equivalent of Adjusted EBITDA, and the use of Adjusted EBITDA margin rather than net income (loss) margin, which is the nearest U.S. GAAP equivalent of Adjusted EBITDA margin. These limitations include that the non-GAAP financial measures: •exclude depreciation and amortization, and although these are non-cash expenses, the assets being depreciated may be replaced in the future; •exclude stock-based compensation expense, which has been, and will continue to be, a significant recurring expense for our business and an important part of our compensation strategy; •do not reflect interest income, primarily resulting from interest income earned on our cash and cash equivalent balances; •do not reflect interest expense, or the cash requirements necessary to service interest or principal payments on our debt, which reduces cash available to us; •do not reflect the effect of foreign currency exchange gains or losses, which is included in other income (expense), net; •do not reflect the provision for or benefit from income tax that may result in payments that reduce cash available to us;

•do not reflect items that are not considered representative of our underlying operating performance which reduce cash available to us; and •may not be comparable to similar non-GAAP financial measures used by other companies, because the expenses and other items that we exclude in our calculation of these non-GAAP financial measures may differ from the expenses and other items, if any, that other companies may exclude from these non-GAAP financial measures when they report their operating results. Because of these limitations, these non-GAAP financial measures should be considered along with other operating and financial performance measures presented in accordance with U.S. GAAP. 27

Our use of open source software could negatively affect our ability to sell our products and subject us to possible litigation. We incorporate open source software into our products, and we may continue to incorporate open source software into our products in the future. Open source software is generally licensed by its authors or other third parties under open source licenses. Some of these licenses contain requirements that we make available source code for modifications or derivative works we create based upon the open source software and that we license such modifications or derivative works under the terms of a particular open source license or other license granting third parties certain rights of further use. Additionally, if a third-party software provider has incorporated open source software into software that we license from such provider, we could be required to disclose any of our source code that incorporates or is a modification of our licensed software. If an author or other third party that distributes open source software that we use or license were to allege that we had not complied with the conditions of the applicable license, we could be required to incur significant legal expenses defending against those allegations and could be subject to significant damages, enjoined from offering or selling our products that contained the open source software and required to comply with the above conditions. Any of the foregoing could disrupt and harm our business and financial condition. We track certain operational and business metrics with internal methods that are subject to inherent challenges in measurement, and real or perceived inaccuracies in such metrics may harm our reputation and negatively affect our business. We calculate certain of our key metrics, including households and registrations, using internal company data that has not been independently verified. While these numbers are based on what we believe to be reasonable calculations for the applicable period of measurement, there are inherent challenges in measuring our key metrics. Our process for tracking these metrics may change over time, including to improve their accuracy, which could result in unexpected changes to the data reported. As our business develops, we may revise or cease reporting certain metrics if we determine that such metrics are no longer accurate or appropriate measures of our performance. If we discover material inaccuracies in our key metrics, or if the metrics we rely on to track our performance do not provide an accurate measurement of our business, or if investors, analysts, or customers do not believe that they do, our reputation may be harmed, and our operating and financial results could be adversely affected.

Our investments in research and development may not yield the results expected. 12 Our business operates in intensely competitive markets characterized by changing consumer preferences and rapid technological innovation. Due to advanced technological innovation and the relative ease of technology imitation, new products and services tend to become standardized more rapidly, leading to more intense competition and ongoing price erosion. In order to strengthen the competitiveness of our products in this environment, we continue to invest heavily in research and development, including to develop new products and services and enhance existing products and services. We must also continue to invest significant resources into maintaining and enhancing our software and platform. However, these investments may not yield the innovation or the results expected on a timely basis, or our competitors may surpass us in technological innovation, hindering our ability to timely commercialize new and competitive products that meet the needs and demands of the market, which consequently may adversely impact our operating results as well as our reputation. If we are not successful in continuing to expand our direct-to-consumer sales channel by driving consumer traffic and consumer purchases through our website, our business and results of operations could be harmed. We have invested significant resources in our direct-to-consumer sales channel, primarily through our website and our app, and our future growth relies, in part, on our continued ability to attract consumers to this channel, which has and will continue to require significant expenditures in marketing, software development and infrastructure. If we are unable to continue to drive traffic to, and increase sales through, our website and our app, our business and results of operations could be harmed. The continued success of direct-to-consumer sales through our website is subject to risks associated with e-commerce, many of which are outside of our control. Our inability to adequately respond to these risks and uncertainties or to successfully maintain and expand our direct-to-consumer business via our website and our app may have an adverse impact on our results of operations. We experience seasonal demand for our products, and if our sales in high-demand periods are below our forecasts, our overall financial condition and operating results could be adversely affected. Our business is seasonal, and we have historically experienced significantly higher revenue in our first fiscal quarter due to increased consumer spending patterns during the holiday season. Given the seasonal nature of our sales, accurate forecasting is critical to our business. Any shortfalls in expected first fiscal quarter revenue could cause our annual operating results to suffer significantly. In addition, if we fail to accurately forecast customer demand for the holiday season, we may experience excess inventory levels or a shortage of products available for sale, which could further harm our financial condition and operating results.

Our efforts to expand beyond our core offerings and offer products and services with wider applications may not succeed and could adversely impact our business. We have, and may in the future continue to, seek to expand beyond our core offerings and develop products and services that have wider applications outside of home sound. For example, in April 2023, we introduced Sonos Pro, our new audio subscription service for businesses and, in June 2024, we introduced Sonos Ace, our new headphones product and entry into the personal listening category. Developing these products and services has and would require us to make significant financial and resource investments, and our ability to successfully establish meaningful market share for these products and services is unproven. It is likely that we would need to hire additional personnel, partner with new third parties and incur considerable research and development expenses to pursue such an expansion successfully. We could encounter difficulties in gaining market acceptance for these products and services due to lower levels of brand recognition and potentially less familiarity by us with consumers preferences in these markets. As a result, we may not be successful in future efforts to achieve profitability from new markets, services or new types of products, and our ability to generate revenue from our existing products and services may suffer. If any such expansion does not enhance our ability to maintain or grow our revenue or recover any associated development costs, our operating results could be adversely affected. If market demand for streaming music does not grow as anticipated or the availability and quality of streaming services does not continue to increase, our business could be adversely affected. A large portion of our customer base uses our products to listen to content via subscription-based streaming music services. Accordingly, we believe our future revenue growth will depend in part on the continued expansion of the market for streaming music. The success of the streaming music market depends on the quality, reliability and adoption of streaming technology and on the continued success of streaming music services such as Apple Music, Spotify, Deezer, and Pandora. If the streaming music market in general fails to expand or if the streaming services that we partner with are not successful, demand for our products may suffer and our operating results may be adversely affected. If we are unable to protect our intellectual property, the value of our brand and other intangible assets may be diminished, and our business may be adversely affected. Our success depends in part on our ability to protect our intellectual property and other proprietary rights. We currently protect, and expect to continue to protect, our intellectual property and other proprietary rights through a combination of confidentiality and license agreements with our employees, consultants and third-party partners and patent, trademark, copyright and trade secret protection laws. In the United States and certain other countries, we have filed various applications for certain aspects of our intellectual property, most notably patents. However, third parties may knowingly or unknowingly infringe our proprietary rights or challenge our proprietary rights, and pending and future patent and trademark applications may not be approved. We may not be 13 able to prevent infringement of our proprietary rights without incurring substantial expense. Such infringement could have a material adverse effect on our brand, business, financial condition and results of operations. We have initiated legal proceedings to protect our intellectual property rights, and we may file additional actions in the future. For example, in January 2020 we filed a complaint with the ITC against Alphabet and Google and a counterpart lawsuit in the U.S. District Court for the Central District of California against Google alleging infringement of five Sonos patents, and in September 2020 we filed another lawsuit against Google alleging infringement of an additional four Sonos patents. See Note 13. Commitments and Contingencies of the notes to our consolidated financial statements included elsewhere in this Form 10-K for further details. The cost and effort of defending our intellectual property have been and may in the future be substantial, and there is no assurance we will be successful. Our business could be adversely affected as a result of any such actions, or a finding that any patents-in-suit are invalid or unenforceable. These actions have led and may in the future lead to additional counterclaims or actions against us, which are expensive to defend against and for which there can be no assurance of a favorable outcome. For example, Google has responded to our legal proceedings by filing multiple patent infringement lawsuits against us in the U.S. District Court for the Northern District of California, cases against us in the ITC, and patent infringement lawsuits against us and our subsidiary Sonos Europe B.V. in various foreign jurisdictions. See Note 13. Commitments and Contingencies of the notes to our consolidated financial statements included elsewhere in this Form 10-K for further details. Further, parties we bring legal action against could retaliate through non-litigious means, which could harm our ability to compete against such parties or to enter new markets. In addition, the regulations of certain foreign countries do not protect our intellectual property rights to the same extent as the laws of the United States. We have and may in the future discover unauthorized products in the marketplace that are counterfeit reproductions of our products. If we are unsuccessful in pursuing producers or sellers of counterfeit products, continued sales of these products could adversely impact our brand, business, financial condition and results of operations.

We currently are, and may continue to be, subject to intellectual property rights claims and other litigation which are expensive to support, and if resolved adversely, could have a significant impact on us and our stockholders. Companies in the consumer electronics industries own large numbers of patents, copyrights, trademarks, domain names and trade secrets, and frequently enter into litigation based on allegations of infringement, misappropriation or other violations of intellectual property or other rights. Given our high profile and as we face more intense competition in our markets and introduce more products and services, including through acquisitions and through partners, the possibility of intellectual property rights claims against us grows. Our technologies may not be able to withstand any third-party claims or rights against their use, and we may be subject to litigation and disputes. The costs of supporting such litigation and disputes are considerable, and there can be no assurance that a favorable outcome would be obtained. We may be required to settle such litigation and disputes, or we may be subject to an unfavorable judgment in a trial, and the terms of a settlement or judgment against us may be unfavorable and require us to cease some or all our operations, limit our ability to use certain technologies, pay substantial amounts to the other party or issue additional shares of our capital stock to the other party, which would dilute our existing stockholders. Further, if we are found to have engaged in practices that are in violation of a third party's rights, we may have to negotiate a license to continue such practices, which may not be available on reasonable or favorable terms, or may have to develop alternative, non-infringing technology or discontinue the practices altogether. In the event that these practices relate to an acquisition or a partner, we may not be successful in exercising any indemnification rights available to us under our agreements or in recovering damages in the event that we are successful. Each of these efforts could require significant effort and expense and ultimately may not be successful. If we are not able to maintain and enhance the value and reputation of our brand, or if our reputation is otherwise harmed, our business and operating results could be adversely affected. Our continued success depends on our reputation for providing high-quality products and consumer experiences, and the "Sonos" name is critical to preserving and expanding our business. Our brand and reputation are dependent on a number of factors, including our marketing efforts, product and platform quality, and trademark protection efforts, each of which requires significant expenditures. The value of our brand could also be severely damaged by isolated incidents, which may be outside of our control. For example, in the United States, we rely on custom installers of home audio systems for a significant portion of our sales but maintain no control over the quality of their work and thus could suffer damage to our brand or business to the extent such installations are unsatisfactory or defective. In addition, certain of our customers and partners experienced performance issues with our redesigned Sonos app launched in May 2024, which has negatively affected, and could further negatively affect, our brand and reputation. See "We face risks related to the adoption and operations of our redesigned Sonos app" above for further details. Any damage to our brand or reputation may adversely affect our business, financial condition and operating results.

We sell our products through a limited number of key channel partners, and the loss of any such channel partner would adversely impact our business. We are dependent on our channel partners for a vast majority of our product sales. Best Buy, one of our key channel partners, accounted for 17% of our revenue in fiscal 2023. We compete with other consumer products for placement and promotion of our products in the stores of our channel partners, including in some cases products of our channel partners. Our contracts with our channel partners allow them to exercise significant discretion in the placement and promotion of our products, and such contracts do not contain any long-term volume commitments. If one or several of our channel partners do not effectively market and sell our products, discontinue or reduce the inventory of our products, increase the promotions of or choose to promote competing products over ours, the volume of our products sold to customers could decrease, and our business and results of operations would therefore be significantly harmed. Many of our key channel partners temporarily closed or reduced operations in their retail stores at various times during the pandemic and may continue to do so in the future, which has had, and may continue to have, a material effect on our business and results of operations. Revenue from our channel partners also depends on a number of factors outside our control and may vary from period to period. One or more of our channel partners may experience serious financial difficulty, particularly in light of the impact of the pandemic on the retail sector, may consolidate with other channel partners or may have limited or ceased operations. Our business and results of operations have been, and may continue to be, significantly harmed by retail store closures by many of our key channel partners. Loss of a key channel partner would require us to identify alternative channel partners or increase our reliance on our direct-to-consumer channel, which may be time-consuming and expensive or we may be unsuccessful in our efforts to do so. We have and may in the future discontinue support for older versions of our products, resulting in customer dissatisfaction that could negatively affect our business and operating results. We have historically maintained, and we believe our customers may expect, extensive backward compatibility for our older products and the software that supports them, allowing older products to continue to benefit from new software updates. We expect that as we continue to improve and enhance our software platform, this backward compatibility will no longer be practical or cost-effective, and we may decrease or discontinue service for our older products. For example, certain of our legacy products continue to work but no longer receive software updates (other than bug fixes and patches). To the extent we no longer provide extensive backward capability for our products, we may damage our relationship with our existing customers, as well as our reputation, brand loyalty and ability to attract new customers. For these reasons, any decision to decrease or discontinue backward capability may decrease sales, generate legal claims and adversely affect our business, operating results and financial condition.

Conflicts with our channel and distribution partners could harm our business and operating results. Several of our existing products compete, and products that we may offer in the future could compete, with the product offerings of some of our significant channel and distribution partners who have greater financial and technical resources than we do. To the extent products offered by our partners compete with our products, they may choose to market and promote their own products over ours or could end our partnerships and cease selling or promoting our products entirely. Any reduction in our ability to place and promote our products, or increased competition for available shelf or website placement, especially during peak retail periods, such as the holiday shopping season, would require us to increase our marketing expenditures and to seek other distribution channels to promote our products. If we are unable to effectively sell our products due to conflicts with our distribution partners or the inability to find alternative distribution channels, our business would be harmed. The expansion of our direct-to-consumer channel could alienate some of our channel partners and cause a reduction in product sales from these partners. Channel partners may perceive themselves to be at a disadvantage based on the direct-to-consumer sales offered through our website. Due to these and other factors, conflicts in our sales channels could arise and cause channel partners to divert resources away from the promotion and sale of our products. Further, to the extent we use our mobile app to increase traffic to our website and increase direct-to-consumer sales, we will rely on application marketplaces such as the Apple App Store and Google Play to drive downloads of our mobile app. Apple and Google, both of which sell products that compete with ours, may choose to use their marketplaces to promote their competing products over our products or may make access to our mobile app more difficult. Any of these situations could adversely impact our business and results of operations.

Competition with our technology partners could harm our business and operating results. We are dependent on a number of technology partners for the development of our products, some of which have developed or may develop and sell products that compete with our products. These technology partners may cease doing business with us or disable the technology they provide our products for a variety of reasons, including to promote their products over our own. For example, we are currently manufacturing and developing voice-enabled speaker systems that are enhanced with the technology of our partners, including those who sell competing products. Our existing voice-enabled speakers are powered by Amazon's Alexa or Google's Google Assistant technology. One or more of our partners could disable their integration on one or all of our voice-enabled products, terminate or not renew their distribution agreement with us, or begin charging us for their integration with our voice-enabled products. For example, our current agreement with Amazon allows Amazon to disable the Alexa integration in our voice-enabled products with limited notice. We cannot assure you that we will be successful in establishing partnerships with other companies that have developed voice-control enablement technology or in developing such technology on our own. If one or more of our technology partners do not maintain their integration with our products or seek to charge us for this integration, or if we have not developed alternative partnerships for similar technology or developed such technology on our own, our sales may decline, our reputation may be harmed and our business and operating results may suffer. Competition with our content partners could cause these partners to cease to allow their content to be streamed on our products, which could lower product demand. Demand for our products depends in large part on the availability of streaming third-party content that appeals to our existing and prospective customers. Compatibility with streaming music services, podcast platforms and other content provided by our content partners is a key feature of our products. To date, all our arrangements have been entered into on a royalty-free basis. Some of these content partners compete with us already, and others may in the future produce and sell speakers along with their streaming services. Additionally, other content partners may form stronger alliances with our competitors in the home audio market. Any of our content partners may cease to allow their content to be streamed on our products for a variety of reasons, including as a result of our offering competing services, to promote other partnerships or their products over our products, or to seek to charge us for this streaming. If this were to happen, demand for our products could decrease, our costs could increase and our operating results could be harmed. 18

Operational Risks We are dependent on a limited number of contract manufacturers to manufacture our products and our efforts to diversify manufacturers may not be successful. We depend on a limited number of contract manufacturers to manufacture our products, with our key manufacturer, Inventec Appliances Corporation, manufacturing a majority of our products. If these companies experience an interruption in their operations, fail to perform their obligations in a timely manner, or terminate their agreement with us, we may be unable to maintain our production capacity without incurring material additional costs and substantial delays or we may be fully prevented from selling our products. In the event that we need to replace a contract manufacturer or transfer volume to another contract manufacturer, we cannot assure you that we would be able to do so on acceptable terms or in a timely manner and such efforts may be costly and time-consuming. Any material disruption in our relationship with our manufacturers would harm our ability to compete effectively and satisfy demand for our products and could adversely impact our revenue, gross margin and operating results. 15 Beginning in fiscal 2020, we have engaged in efforts to diversify our supply chain through the addition of new contract manufacturers and geographic diversification. There is no guarantee that our efforts to diversify manufacturers will continue to be successful and such efforts require a significant amount of time and resources. In addition, if we are not successful in our efforts to onboard new contract manufacturers, we may have an insufficient supply of products to meet customer demand, and our financial performance and reporting may be adversely affected. We depend on a limited number of third-party components suppliers and logistics providers, and many of our components have long lead times, and our business and operating results could be adversely affected by shortages, disruptions and related challenges. We are dependent on a limited number of suppliers for various key components used in our products, and we may from time to time have sole source suppliers. The cost, quality and availability of these components are essential to the successful production and sale of our products. We are subject to the risk of industry-wide shortages, price fluctuations and long lead times in the supply of these components and other materials. If the supply of these components is delayed or constrained, or if one or more of our main suppliers were to go out of business, alternative sources or suppliers may not be available on acceptable terms or at all. In the event that any of our suppliers were to discontinue production of our key product components, developing alternate sources of supply for these components would be time consuming, difficult and costly. In the event we are unable to obtain components in sufficient quantities on a timely basis and on commercially reasonable terms, our ability to sell our products in order to meet market demand would be affected and could materially and adversely affect our brand, image, business prospects and operating results. In addition, the longer lead time for many of our components presents challenges in our efforts to manage component inventory, as we procure such components based on our then current forecast of demand for our products. In the past, we have had to increase our purchase commitments and investments during industry-wide shortages. In the event that actual demand for our products differs from our forecast, we may end up with excess component inventory, as we saw in fiscal 2024, negatively impacting our working capital. We also use a small number of logistics providers for substantially all our product delivery to both distributors and retailers. If one of these providers were to experience financial difficulties or disruptions in its business, or be subject to closures or other disruptions, our own operations could be adversely affected. Because substantially all of our products are distributed from and into a small number of locations and by a small number of companies, we are susceptible to both isolated and system-wide interruptions caused by events out of our control. Any disruption to the operations of our distribution facilities could delay product delivery, harm our reputation among our customers and adversely affect our operating results and financial condition. We have limited control over the third-party suppliers and logistics providers on which our business depends. If any of these parties fails to perform its obligations to us, we may be unable to deliver our products to customers in a timely manner. Further, we do not have long-term contracts with all of these parties, and there can be no assurance that we will be able to renew our contracts with them on favorable terms or at all. We may be unable to replace an existing supplier or logistics provider or supplement a provider in the event we experience significantly increased demand. Accordingly, a loss or interruption in the service of any key party could adversely impact our revenue, gross margin and operating results. We have and may in the future discontinue support for older versions of our products, resulting in customer dissatisfaction that could negatively affect our business and operating results.

Product quality issues and a higher-than-expected number of warranty claims or returns could harm our business and operating results. The products that we sell could contain defects in design or manufacture. Defects could also occur in the products or components that are supplied to us. There can be no assurance we will be able to detect and remedy all defects in the hardware and software we sell, which could result in product recalls, product redesign efforts, loss of revenue, reputational damage and significant warranty and other remediation expenses. Similar to other consumer electronics, our products have a risk of overheating and fire in the course of usage or upon malfunction. Any such defect could result in harm to property or in personal injury. If we determine that a product does not meet product quality standards or may contain a defect, the launch of such product could be delayed until we remedy 16 the quality issue or defect. The costs associated with any protracted delay necessary to remedy a quality issue or defect in a new product could be substantial. We generally provide a one-year warranty on all our products, except in the European Union ("EU") and select other countries where we provide a minimum two-year warranty, depending on the region, on all our products. In addition, as part of our commitments to our customers following the release of our redesigned Sonos app, in October 2024 we extended the warranty by one year for all home theater and plug-in speaker products then under warranty. The occurrence of any material defects in our products could expose us to liability for warranty claims in excess of our current reserves, and we could incur significant costs to correct any defects, warranty claims or other problems. In addition, our failure to comply with past, present and future laws regulating extended warranties and accidental damage coverage could result in reduced sales of our products, reputational damage, penalties and other sanctions, which could harm our business and financial condition.

Our international operations are subject to increased business and economic risks that could impact our financial results. We have operations outside the United States and generate a significant portion of our revenue from international sales. Our products are sold in more than 60 countries and, in fiscal 2024, 38.7% of our revenue was generated outside the United States. This subjects us to a variety of risks inherent in doing business internationally, including: •fluctuations in currency exchange rates and costs of imposing currency exchange controls; •political, social and/or economic instability; •tariffs, trade barriers and duties; •protectionist laws and business practices that favor local businesses in some countries; •higher levels of credit risk and payment fraud and longer payment cycles associated with, and increased difficulty of payment collections from certain international customers; •burdens and risks of complying with a number and variety of foreign laws and regulations, including the Foreign Corrupt Practices Act; •laws and regulations may change from time to time unexpectedly and may be unpredictably enforced; •potential negative consequences from changes in or interpretations of U.S. and foreign tax laws; •the cost of developing connected products for countries where Wi-Fi technology has been passed over in favor of more advanced cellular data networks; •reduced protection for intellectual property rights in some countries;

Legal and Regulatory Risks Changes in international trade policies, including the imposition of tariffs have had, and may continue to have, an adverse effect on our business, financial condition and results of operations. In the past, the U.S. government imposed significant tariffs on China related to the importation of certain product categories, including those under the August 2019 Section 301 Tariff Action (List 4A) ("Section 301 tariffs"). These Section 301 tariffs increased our cost of revenue and adversely impacted our results of operations. We were able to obtain an exemption from the Section 301 tariffs for certain of our products, including our core speaker products, for certain periods since fiscal 2020, with the exemption for our core speaker product having expired in June 2024. To date, we have recovered virtually all refunds to which we are entitled on tariffs paid through fiscal 2022. In addition, we have relocated a substantial portion of our contract manufacturing from China to Malaysia and Vietnam, mitigating the effects of the Section 301 tariffs on a going forward basis. It remains unclear what the U.S. or foreign governments will do with respect to tariffs, international trade agreements and policies on a short-term or long-term basis. In the event of expansion of trade restrictions, the imposition of future tariffs on imports of our products or other government actions related to tariffs or trade agreements, our business may be impacted and we may be required to raise prices or make changes to our operations, any of which could materially harm our revenue or operating results. We must comply with extensive regulatory requirements, and the cost of such compliance, and any failure to comply or perceived failure to comply, may adversely affect our business, financial condition and results of operations. In our current business and as we expand into new markets and product categories, we must comply with a wide variety of laws, regulations, standards and other requirements governing, among other things, electrical safety, wireless emissions, health and safety, e-commerce, consumer protection, export and import requirements, hazardous materials usage, product related energy consumption, packaging, recycling and environmental matters. Compliance with these laws, regulations, standards and other requirements may be onerous and expensive, and they may be inconsistent from jurisdiction to jurisdiction or change from time to time, further increasing the cost of compliance and doing business. Our products may require regulatory approvals or satisfaction of other regulatory concerns in the various jurisdictions in which they are manufactured, sold or both. These requirements create procurement and design challenges that require us to incur additional costs identifying suppliers and manufacturers who can obtain and produce compliant materials, parts and products. Failure to comply with such requirements can subject us to liability, additional costs and reputational harm and, in extreme cases, force us to recall products or prevent us from selling our products in certain jurisdictions. 19 We may incur costs in complying with changing tax laws in the United States and abroad, which could adversely impact our cash flow, financial condition and results of operations. We are a U.S.-based company subject to taxes in multiple U.S. and foreign tax jurisdictions. Our effective tax rate, as well as our business, operating results and financial condition, could be adversely affected by changes in the tax rules and regulations in the jurisdictions in which we do business, unanticipated changes in statutory tax rates and changes to our global mix of earnings. As we expand our operations, any changes in the U.S. or foreign taxation of such operations may increase our worldwide effective tax rate. We are also subject to examination by the Internal Revenue Service ("IRS") and other tax authorities, including state revenue agencies and foreign governments. If any tax authority disagrees with any position we have taken, our tax liabilities and operating results may be adversely affected. While we regularly assess the likelihood of favorable or unfavorable outcomes resulting from examinations by the IRS and other tax authorities to determine the adequacy of our provision for income taxes, there can be no assurance that the actual outcome resulting from these examinations will not materially adversely affect our financial condition and results of operations. In addition, the distribution of our products subjects us to numerous complex and often-changing customs regulations. Failure to comply with these systems and regulations could result in the assessment of additional taxes, duties, interest and penalties. There is no assurance that tax and customs authorities agree with our reporting positions and upon audit may assess us additional taxes, duties, interest and penalties. If this occurs and we cannot successfully defend our position, our profitability will be reduced.

Our ability to use our net operating loss carryforwards and certain other tax attributes may be limited. As of September 28, 2024, we had gross state net operating loss carryforwards of $33.4 million, which expire beginning in 2032, as well as $39.9 million in foreign net operating loss carryforwards with an indefinite life. As of September 28, 2024, we also had U.S. federal research and development tax credit carryforwards as filed of $37.6 million, and state research and development tax credit carryforwards as filed of $48.0 million, which will expire beginning in 2041 and 2026, respectively. Because of the change of ownership provisions of Sections 382 and 383 of the Code, use of a portion of the Company's domestic net operating losses and tax credit carryforwards may be limited in future periods depending upon future changes in ownership. Further, a portion of the carryforwards may expire before being applied to reduce future income tax liabilities if sufficient taxable income is not generated in future periods.

Risks Related to Ownership of Our Common Stock The stock price of our common stock has been and may continue to be volatile or may decline regardless of our operating performance. The stock price of our common stock has been and may continue to be volatile. The stock price of our common stock may fluctuate significantly in response to numerous factors in addition to the ones described in the preceding Risk Factors, many of which are beyond our control, including: •overall performance of the equity markets and the economy as a whole; •changes in the financial projections we or third parties may provide to the public or our failure to meet these projections; •actual or anticipated changes in our growth rate relative to that of our competitors; •announcements of new products, or of acquisitions, strategic partnerships, joint ventures or capital-raising activities or commitments, by us or by our competitors; •additions or departures of key personnel; •failure of securities analysts to maintain coverage of us, changes in financial estimates by any securities analysts who follow our company or our failure to meet these estimates or the expectations of investors; •rumors and market speculation involving us or other companies in our industry; •sales of shares of our common stock by us or our stockholders particularly sales by our directors, executive officers and significant stockholders, or the perception that these sales could occur; and

•additional stock issuances that result in significant dilution to shareholders. In addition, the stock market with respect to companies in the technology industry has experienced significant price and volume fluctuations that have affected and continue to affect the stock prices of these companies. In the past, stockholders have instituted securities class action litigation following periods of market volatility. If we were to become involved in securities litigation, it could subject us to substantial costs, divert resources and the attention of management from our business and adversely affect our business.

We do not intend to pay dividends for the foreseeable future. 20 We have never declared or paid any cash dividends on our common stock, and we do not intend to pay any cash dividends in the foreseeable future. We anticipate that we will retain all our future earnings for use in the development of our business and for general corporate purposes. Any determination to pay dividends in the future will be at the discretion of the Board. Accordingly, investors must rely on sales of their common stock after price appreciation, which may never occur, as the only way to realize any future gains on their investments. In addition, the terms of our credit facilities contain restrictions on our ability to declare and pay cash dividends on our capital stock. Certain provisions in our corporate charter documents and under Delaware law may prevent or hinder attempts by our stockholders to change our management or to acquire a controlling interest in us. There are provisions in our restated certificate of incorporation and restated bylaws that may make it difficult for a third party to acquire, or attempt to acquire, control of our company, even if a change in control were considered favorable by our stockholders. These anti-takeover provisions include: •a classified Board so that not all members of the Board are elected at one time; •the ability of the Board to determine the number of directors and fill any vacancies and newly created directorships; •a requirement that our directors may only be removed for cause; •a prohibition on cumulative voting for directors; •the requirement of a super-majority to amend some provisions in our restated certificate of incorporation and restated bylaws; •authorization of the issuance of "blank check" preferred stock that the Board could use to implement a stockholder rights plan;

•an inability of our stockholders to call special meetings of stockholders; and •a prohibition on stockholder actions by written consent, thereby requiring that all stockholder actions be taken at a meeting of our stockholders. In addition, our restated certificate of incorporation provides that the Delaware Court of Chancery is the exclusive forum for any derivative action or proceeding brought on our behalf; any action asserting a breach of fiduciary duty; any action asserting a claim against us arising pursuant to the Delaware General Corporation Law (the "DGCL"), our restated certificate of incorporation or our restated bylaws; or any action asserting a claim against us that is governed by the internal affairs doctrine. Our restated certificate of incorporation also provides that the federal district courts of the United States will be the exclusive forum for resolving any complaint asserting a cause of action arising under the Securities Act of 1933, as amended. Further, Section 203 of the DGCL may discourage, delay or prevent a change in control of our company. Section 203 imposes certain restrictions on mergers, business combinations, and other transactions between us and holders of 15% or more of our common stock.

We may need additional capital, and we cannot be certain that additional financing will be available. In October 2021, we entered into a credit agreement with JPMorgan Chase Bank, N.A., Bank of America N.A., Morgan Stanley Senior Funding, Inc., and Goldman Sachs Bank USA (the "Revolving Credit Agreement"), which allows us to borrow up to $100.0 million, with a maturity date of October 2026. We may require additional equity or debt financing to fund our operations and capital expenditures. Our ability to obtain financing will depend, among other things, on our development efforts, business plans, operating performance and the condition of the capital markets at the time we seek financing. We cannot assure you that additional financing will be available to us on favorable terms if and when required, or at all. We have and may in the future acquire other businesses or receive offers to be acquired, which could require significant management attention, disrupt our business, dilute stockholder value and adversely affect our operating results. As part of our business strategy, we have and may in the future make investments in complementary businesses, products, services or technologies. These acquisitions and other transactions and arrangements involve significant challenges and risks, including not advancing our business strategy, receiving an unsatisfactory return on our investment, difficulty integrating and retaining new employees, business systems, and technology, or distracting management from our other business initiatives. If an arrangement fails to adequately anticipate changing circumstances and interests of a party, it may result in early termination or renegotiation of the arrangement. The success of these transactions and arrangements will depend in part on our ability to leverage them to enhance our existing products or develop compelling new ones. It may take longer than expected to realize the full benefits from these transactions and arrangements such as increased revenue or enhanced efficiencies, or the benefits may ultimately be smaller than we expected. These events could adversely affect our consolidated financial statements. If we fail to maintain an effective system of internal controls in the future, we may experience a loss of investor confidence and an adverse impact to our stock price. Pursuant to the Sarbanes-Oxley Act of 2002, we are required to document and test our internal control procedures and to provide a report by management on internal control over financial reporting, including management's assessment of the effectiveness of such control. If we are unable to maintain effective internal control over financial reporting or disclosure controls and procedures, our ability to record, process and report financial information accurately, and to prepare consolidated financial statements within required time periods could be adversely affected, which could subject us to litigation or investigations requiring management resources and payment of legal and other expenses, negatively affect investor confidence in our consolidated financial statements and adversely impact our stock price.

The home audio and consumer electronics industries are highly competitive. The markets in which we operate are extremely competitive and rapidly evolving, and we expect that competition will intensify in the future. Our competition includes established, well-known sellers of audio products such as Bose, Samsung (and its subsidiaries Harman International and JBL), Sony, Bang & Olufsen, Sennheiser, Apple, Google, Amazon, and Masimo (and its subsidiary Sound United that owns, among others, the Denon, Polk Audio and Bowers and Wilkens brands). We could also face competition from new market entrants, some of whom might be current partners of ours. Many of our competitors have greater financial, technical and marketing resources than we do, which may allow them to more frequently introduce new products and services, invest more in research and development, incorporate technological advances into their products and services on a faster basis including artificial intelligence ("AI") technology, improve the performance of their products and services more frequently, implement and sustain aggressive pricing policies, have access to broader sales and distributions channels and the ability to exert more influence over these channels, and expend more on sales and marketing efforts. In particular, we have seen our competitors sell their products at a significant discount to ours from time to time. In addition, many of our competitors may subsidize the prices of speaker products and seek to monetize their customers through the sale of additional services rather than the speakers themselves. Our ability to compete successfully depends on our ability to introduce and deliver products and services that appeal to consumers, including by developing superior and innovative technology, offering a differentiated customer experience, including through our app, anticipating increasingly diverse consumer tastes and rapidly developing attractive products and services with competitive selling prices. Even if we are able to efficiently develop and offer innovative products and services at competitive selling prices, our operating results and financial condition may be adversely impacted if we are unable to effectively anticipate and counter the ongoing price erosion that frequently affects the highly competitive consumer electronics industry or if the average selling prices of our products and services decrease faster than we are able to reduce our manufacturing costs. We must also overcome the fact that a relatively high percentage of consumers may already own or use products that they perceive to be similar to those that we offer. Certain of our competitors have established, or may establish, cooperative relationships among themselves or with third parties to increase the abilities of their products to address the needs of our prospective customers, and other companies may enter our markets by entering into strategic relationships with our competitors. A failure to effectively anticipate and respond to these established and new competitors may adversely impact our business and operating results. Further, our current and prospective competitors may consolidate with each other or make acquisitions that would intensify the competition that we face, including by acquiring companies that will allow them to develop products that better compete with our products, or that would disrupt our business, including by acquiring one of our distribution, technology or content partners. For example, if one of our competitors were to acquire one of our content partners, the consolidated company may decide to disable the streaming functionality of its service with our products. If we are unable to compete with these consolidated companies or if consolidation in the market disrupts our partnerships or reduces the number of companies we partner with, our business would be adversely affected.

Our software includes the following key benefits: •Multi-room, multi-service experience. Our system enables our speakers to work individually or together in synchronized playback groups, powered by wireless network and Bluetooth capabilities to route and play audio optimally from all the different content services that our customers enjoy. •Open platform for content partners. Our platform enables customers to easily search and browse for content from a list of more than 100 content partners from around the world including stations, artists, albums, podcasts, audio books, and more. Content partners can connect to Sonos via our platform and find a new and growing audience for their catalogs. •Intuitive and flexible control. Our customers can control their experiences through the Sonos app, voice control, from Sonos devices directly, or an expanding number of third-party apps and smart devices. As our customers navigate across different controllers, our technology synchronizes the control experience across the Sonos platform to deliver the music and entertainment experience they desire. •Smart audio tuning. Our Trueplay technology uses the microphones on an iOS device to analyze room attributes, speaker placement and other acoustic factors to improve sound quality. We also developed Automatic TruePlay to deliver the same audio tuning experience, directly using the microphones integrated to our speakers and make this available to iOS and Android users. •Sonos Voice Control. Designed with privacy at its core, Sonos Voice Control is the simplest way to control your music, offering complete command of your Sonos system using only your voice. Sonos Voice Control works on every voice-capable Sonos speaker, processing requests entirely on the Sonos device. •Continuous Improvement. Our software platform and cloud service enables feature enhancements and delivery of new experiences on an ongoing basis. As a result, the Sonos experience improves for customers over time.

Item 1: Business Overview Sonos is one of the world's leading sound experience brands. We pioneered multi-room, wireless audio products, debuting the world's first multi-room wireless sound system in 2005. Today, our products include wireless, portable and home theater speakers, components, and accessories to address consumers' evolving audio needs. We are known for delivering unparalleled sound, thoughtful design aesthetic, simplicity of use, and an open platform. Our platform has attracted a broad range of more than 130 streaming content providers, such as Apple Music, Spotify, Deezer, and Pandora. These partners find value in our independent platform and access to our millions of desirable and engaged customers. We frequently introduce new services and features across our platform, providing our customers with enhanced functionality, improved sound, and an enriched user experience. We are committed to continuous technological innovation as reflected in our growing global patent portfolio. We believe our patents comprise the foundational intellectual property for wireless multi-room and other audio technologies. Since we launched our first product 18 years ago, we have grown our install base by launching innovative new products, delivering a seamless customer experience, and expanding our global footprint. In fiscal 2023, existing customers accounted for approximately 44% of new product registrations. As of September 30, 2023, we had a total of nearly 46.6 million products registered in approximately 15.3 million households globally, including the addition of approximately 1.3 million new households during fiscal 2023. Our customers have typically purchased additional Sonos products over time. As of September 30, 2023, 60% of our 15.3 million households had registered more than one Sonos product. As of September 30, 2023, our households own 3.0 products on average.

Manufacturing, Logistics and Fulfillment We outsource the manufacturing of our speakers and components to contract manufacturers, who produce our products based on our design specifications. Our products are manufactured by contract manufacturers in China and Malaysia, and Vietnam. In fiscal 2023, we began the process of exiting certain partnerships with two of our contract manufacturers and we expect to complete these exits with minimal disruption by the first quarter of fiscal 2024. Additionally, we continued to diversify and add to our contract manufacturing partnerships and shifted more of our production into our locations in Malaysia and Vietnam, resulting in savings including tariff avoidance. In accordance with our agreements with our contract manufacturers, they will enter into purchase orders with their upstream suppliers for component inventory necessary to manufacture our products, based on our demand forecasts. The vast majority of our products are shipped to our third-party warehouses which are then shipped to our distributors, retailers, and directly to our customers. Our third-party warehouses are located in the United States in California and Pennsylvania, as well as internationally in Australia, Canada, the Netherlands, China, Japan, and the United Kingdom. We use a small number of logistics providers for substantially all of our product delivery to both distributors and retailers. This approach generally allows us to reduce order fulfillment time, reduce shipping costs, and improve inventory flexibility.

•implementing mentoring and allyship programs that connect employees to key support systems across Sonos; and •deepening our organizational acumen around allyship, unconscious bias, and equity. Community Involvement. We aim to enhance the communities where we live and work, and believe that this commitment helps in our efforts to attract and retain employees. We offer employees the opportunity to give back both through our Sonos Soundwaves program, which partners with leading non-profits, and our Sonos Cares program, which offers employees paid volunteer time each year.

Our Partner Ecosystem We have built a platform that attracts partners to enable our customers to play content from their preferred services. Our platform has attracted a broad range of more than 100 streaming content providers, such as Apple Music, Spotify, Deezer, and Pandora. These partners find value in our independent platform and access to our millions of desirable and engaged customers. Our partner ecosystem spans across content, control, and third-party applications: •Content. We partner with a broad range of content providers, such as streaming music services, internet radio stations, and podcast services, allowing our customers to enjoy their audio content from whichever source they desire. •Control. We provide our customers with multiple options to control their home audio experiences, including voice control and direct control from within selected streaming music service apps. Our platform is the first to offer consumers the ability to buy a single smart speaker with more than one voice assistant choice. Our voice-enabled speaker products have Amazon Alexa and Google Assistant functionality, and in June 2022, we introduced Sonos Voice Control. •Third-party partnerships. We partner with third-party developers to build new applications and services on top of the Sonos platform, increasing customer engagement and creating new experiences for our customers, such as architectural in-ceiling, in-wall and outdoor speakers in partnership with Sonance, and automotive sound in partnership with Audi.

Intellectual Property Intellectual property is an important aspect of our business, and we seek protection for our intellectual property as appropriate. To establish and protect our proprietary rights, we rely upon a combination of patent, copyright, trade secret and trademark laws, and contractual restrictions such as confidentiality agreements, licenses and intellectual property assignment agreements. We maintain a policy requiring our employees, contractors, consultants and other third parties to enter into confidentiality and proprietary rights agreements to control access to our proprietary information. These laws, procedures and restrictions provide only limited protection, and any of our intellectual property rights may be challenged, invalidated, circumvented, infringed or misappropriated. There is no guarantee that we will prevail on any patent infringement claims against third parties. Furthermore, the laws of certain countries do not protect proprietary rights to the same extent as the laws of the United States, and we therefore may be unable to protect our proprietary technology in certain jurisdictions. Sonos is a leading innovator that holds a comprehensive portfolio of intellectual property rights, including patents, trade secrets, copyrights, trademarks, service marks, trade dress and other forms of intellectual property rights in the U.S. and various other countries. Sonos' patent portfolio, in particular, has been recognized as one of the strongest in consumer electronics. Our patents and patent applications relate to hardware, software, networking, accessories, and services, and include technology for the ability to stream content for playback wirelessly to one or more rooms in the home or business. It also includes technology for enabling a wide range of experiences and audio technologies that are important to the Sonos platform and enjoyed by millions of people every day across the globe. Experiences covered by our patents include simple system setup, seamless integration with other platforms and services, balanced sound, voice interactions and control, as well as experiences unique to home theater to name a few. We regularly file patent applications in the U.S. and throughout the world to protect our innovations and technology that come from areas such as research, development, and design. Our patents expire at various times and no single patent or other intellectual property right is solely responsible for protecting Sonos' products and services. Sonos continues to invest in protecting its expanding innovation through ongoing development of its patent portfolio. In addition to its own intellectual property, Sonos also enters into licensing agreements with our third-party partners to provide access to a broad range of technology, services, and content for our customers. In January 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 alleging infringement of five Sonos patents. In September 2020, the Company filed another lawsuit against Google alleging infringement of an additional four Sonos patents. In December 2020, the Company filed another lawsuit against Google Germany Gmbh and Google Ireland Ltd. in the regional court of Hamburg, Germany, alleging infringement of a Sonos patent. The ITC case has concluded with a finding of all five Sonos patents infringed by Google and not invalid. The appeals court has affirmed this finding. The California case has concluded with a jury verdict against Google but the court holding the Sonos patents unenforceable and invalid. The California case is awaiting appeal. The Company has since withdrawn the German case. Starting in 2020, Google has responded by filing patent infringement lawsuits against the Company in the ITC, U.S. District Court for the Northern District of California, Canada, Germany, France, and the Netherlands, and patent infringement lawsuits against the Company's subsidiary, Sonos Europe B.V., in Germany, France, and the Netherlands. One ITC case concluded with a finding of no violation by the Company and was not appealed. The other ITC case is awaiting a ruling by the judge. The cases in Canada, Germany, France, and the Netherlands have been decided against Google. In the California case, all of Google's patent claims have been dismissed or decided against Google.

Human Capital Sonos is dedicated to creating the ultimate listening experience for our customers, and our employees are critical to achieving this mission. In order to continue to design innovative experiences and products, and compete and succeed in our highly competitive and rapidly evolving market, it is crucial that we continue to attract and retain talented employees. As part of these efforts, we strive to offer a competitive compensation and benefits program, foster a community where everyone feels included and empowered to do their best work, and give employees the opportunity to give back to their communities and make a social impact. As of September 28, 2024, we had 1,708 full-time employees. Additionally, we use independent contractors and temporary personnel to supplement our workforce. Of our full-time employees, 1,235 were in the United States and 473 were in our international locations. Except for our employees in France and the Netherlands, none of our employees are represented by a labor union or covered by a collective bargaining agreement. Compensation and Benefits Program. Our compensation program is designed to attract and reward talented individuals who possess the skills necessary to support our business objectives, assist in the achievement of our strategic goals and create long-term value for our stockholders. We provide employees with compensation packages that include base salary, cash incentive bonuses, and long-term equity awards ("RSUs") tied to the value of our stock price. We believe that a compensation program with both short-term and long-term awards provides fair and competitive compensation and aligns employee and stockholder interests, including by incentivizing business and individual performance (pay for performance), motivating based on long-term company performance and integrating compensation with our business plans. In addition to cash and equity compensation, we also offer employees benefits such as life and health (medical, dental & vision) insurance, paid time off, paid parental leave, and a 401(k) plan with employer matching.

We monitor the representation of women and racially or ethnically diverse team members at different levels throughout the company and disclose the composition of our team in our annual Listen Better Report, which is our corporate social responsibility report available on the Sustainability & Impact section of our website. As an organization, we've committed to annual diversity, equity and inclusion goals to increase representation at all levels and foster greater connection and belonging at Sonos. To accomplish these goals, we're implementing initiatives to help us reach these goals, including: •holding management directly accountable in creating a more diverse and inclusive environment by designating 10% of the annual cash incentive plan for management for diversity, equity and inclusion goals; •examining our hiring practices to ensure we source the best talent from the widest available pool; •intentional listening to our employee resource groups who provide critical insight into the experience of underrepresented groups at Sonos and across our industry; •frequent review of our policies and practices to ensure an equitable experience for all; 9 •coupling our hiring goals with a focus on retention, employee engagement, and inclusive leadership;
