Sonos Inc,
Fiscal Year 2025.

The following table presents a reconciliation of net loss to adjusted EBITDA: Fiscal Year Ended September 27,2025September 28,2024September 30,2023 (In thousands, except percentages)

Research and Development Research and development expenses consist primarily of personnel-related expenses, third-party resources expenses, tooling, test equipment, prototype materials, and related overhead costs. To date, software development costs have been expensed as incurred because the period between achieving technological feasibility and the release of the software has been short and development costs qualifying for capitalization have been insignificant. Research and development expenses excluding restructuring and other charges decreased $31.4 million, or 10.5%, for fiscal 2025 compared to fiscal 2024. This decrease was primarily driven by lower personnel-related costs due to lower headcount and our reorganization efforts, partially offset by higher variable compensation costs.

General and Administrative General and administrative expenses consist of administrative personnel-related expenses for our information technology, finance, legal, human resources, and similar personnel, as well as the costs of professional services, information technology, litigation, patents, related overhead, and other administrative expenses. 30 General and administrative expenses excluding restructuring and other charges decreased $26.8 million, or 19.3%, for fiscal 2025 compared to the fiscal 2024. This decrease was primarily driven by lower personnel-related costs, professional fees and information technology costs as a result of lower headcount and our cost transformation efforts.

Debt Obligations On October 13, 2021, we 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 provided 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 27, 2025, we did not have outstanding borrowings and $2.4 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 27, 2025, we were in compliance with all financial covenants under the Revolving Credit Agreement. In October 2025, we amended the Revolving Credit Agreement. See Note 14. Subsequent Event of the notes to our consolidated financial statements included elsewhere in this Annual Report on Form 10-K for further details.

Total revenue$1,518,056 100.0 %$1,655,255 100.0 %$(137,199)(8.3)% Volume data (products sold in thousands)Units % Total products sold5,0005,725(725)(12.7)% Total revenue decreased $137.2 million, or 8.3% for fiscal 2024 compared to fiscal 2023, primarily due to softer demand across all regions due to market conditions and challenges resulting from our recent app rollout, partially offset by the introduction of Ace in June 2024, and the impact of favorable foreign exchange rates. Sonos speakers represented 77.0% of total revenue for fiscal 2024 and decreased 9.6% compared to fiscal 2023, primarily driven by expected declines in Sonos One and softer demand across the category, particularly in our home theater products. These declines were partially offset by sales of Era 100 and Era 300 which were introduced in March 2023, and by the introduction of Ace in June 2024. Sonos system products represented 17.6% of total revenue for fiscal 2024 and decreased 6.1% compared fiscal 2023. Partner products and other revenue represented 5.3% of total revenue for fiscal 2024, and increased 5.2% compared to the twelve months ended September 30, 2023. The volume of products sold decreased 12.7% for fiscal 2024, compared to fiscal 2023, primarily driven by expected declines in units of Sonos One, and softer demand, particularly in our home theater products. These declines were partially offset by sales of Era 100 and Era 300, as well as the introduction of Ace in June 2024. The decrease in volume of products sold outpaced that of revenue due to the impact of product mix. 28

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 2025 are to our 52-week fiscal year ended September 27, 2025, 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 and references to fiscal 2022 are to our 52-week fiscal year ended October 1, 2022.

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 loss and net loss margin, respectively.

Total other income (expense), net $(29)$20,895 $(20,924)(100.1)% Interest income consists primarily of interest income earned on our cash, cash equivalents, and marketable securities balances. Interest expense consists primarily of interest expense associated with our debt financing arrangements and amortization of debt issuance costs. Other income (expense), net consists primarily of our foreign currency exchange gains and losses relating to transactions and remeasurement of asset and liability balances denominated in currencies other than the U.S. dollar. We expect our foreign currency gains and losses to continue to fluctuate in the future due to changes in foreign currency exchange rates. Interest income for fiscal 2025 compared to fiscal 2024 decreased primarily due to lower yields on our cash and cash equivalents combined with lower average cash balances. Interest expense for fiscal 2025, compared to fiscal 2024, increased primarily due to increased bank fees. The increase in other income (expense), net for fiscal 2025, compared to fiscal 2024, was primarily due to non-cash foreign currency exchange fluctuations.

Comparison of Fiscal Years 2024 and 2023 For the comparison of fiscal years 2024 and 2023, refer to Part II, Item 7 "Management's discussion and analysis of financial condition and results of operations" on Form 10-K for fiscal 2024, filed with the SEC on November 15, 2024, under the subheading "Comparison of fiscal years 2024 and 2023."

Liquidity and Capital Resources Our operations are financed primarily through cash flows from operating activities. As of September 27, 2025, our principal sources of liquidity consisted of cash flows from operating activities, cash and cash equivalents of $174.7 million, including $105.5 million held by our foreign subsidiaries, marketable securities of $52.9 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 27, 2025, as they are required to fund needs 31 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 paid, 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. In October 2025, we amended the Revolving Credit Agreement. See Note 14. Subsequent Event of the notes to our consolidated financial statements included elsewhere in this Annual Report on Form 10-K for further details. 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 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.

Cash Flows Fiscal 2025 Changes in Cash Flows The following table summarizes our cash flows for the periods indicated: Fiscal Year Ended (In thousands)September 27, 2025September 28, 2024

Net increase (decrease) in cash and cash equivalents $4,936 $(50,499) Cash Flows from Operating Activities Net cash provided by operating activities of $136.9 million for fiscal 2025 consisted of a net loss of $61.1 million, non-cash adjustments of $170.1 million, and a favorable impact of net changes in operating assets and liabilities of $27.9 million. Non-cash adjustments primarily consisted of stock-based compensation expense, depreciation and amortization, and non-cash restructuring charges. The net increase in cash from the change in operating assets and liabilities was primarily due to a decrease in inventories of 32 $51.7 million as the result of measures taken to more efficiently manage inventory, a decrease in other assets of $10.5 million, and an increase in accrued compensation of $5.2 million. The net increase in cash from the change in operating assets and liabilities was partially offset by an increase in accounts receivable of $21.9 million, and a decrease in accounts payable and accrued expenses of $14.4 million due to lower inventory purchases.

Cash Flows from Financing Activities Cash used in financing activities of $102.3 million for fiscal 2025, primarily consisted of payments for repurchase of common stock of $81.0 million and payments for repurchase of common stock related to shares withheld for tax in connection with vesting of stock awards of $25.9 million, partially offset by proceeds from the exercise of options of $4.5 million.

Fiscal 2024 Changes in Cash Flows For the comparison of fiscal 2024 to fiscal 2023, refer to Part II, Item 7 "Management's discussion and analysis of financial condition and results of operations" of our Form 10-K for fiscal 2024, filed with the SEC on November 15, 2024, under the subheading "Liquidity and capital resources."

Contractual obligations See Note 6. Leases and Note 12. Commitments and Contingencies of the notes to our consolidated financial statements included elsewhere in this Annual Report on Form 10-K for further details.

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. 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.

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 architectural speakers and 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 price at which we sell our products, the introduction of new products that may have higher or lower than average selling prices, the impact of foreign exchange fluctuations, as well as the impact of recognition of previously deferred revenue.

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. Starting in 2018, the U.S. government imposed significant tariffs on China for U.S.-bound goods in our product categories. We received exemptions to almost all of those tariffs until such time as we were able to diversify our supply chain, primarily to Vietnam and Malaysia. As a result, our reliance on China for our U.S.-bound products is expected to be very modest. There is significant uncertainty about the future of trade relationships around the world, including potential changes to trade laws and regulations, trade policies, and tariffs. For example, the U.S. government has recently instituted or proposed changes to international trade policy and agreements including the imposition of tariffs on China and countries other than China, in many cases significantly and including countries in Southeast Asia and EMEA. Our business may be impacted by the potential expansion of tariffs on U.S.-bound goods imported from other countries including, but not limited to, Vietnam and Malaysia. In addition, many countries have considered or instituted retaliatory policies, including reciprocal tariffs, in response to these proposed U.S. tariffs. To the extent that tariffs imposed by the United States or by other countries increase the price of, or limit the amount or availability of, our products or components or materials used in our products, or increase logistics costs or cause delays, our business and results of operations may be adversely affected. We may be required to raise our prices, which may result in the loss of customers, or we may choose to pay for these tariffs or additional costs without raising prices, either of which may negatively impact our business and results of operation. In addition, a trade war, and uncertainty regarding international trade policies, could have a significant adverse effect on our business, including by impacting our supply chain and logistics providers, the domestic and world economies and consumer confidence, sentiment and spending, with a corresponding adverse effect on the demand for and prices of our products. It remains unclear what actions the U.S. or foreign governments will take with respect to tariffs, international trade agreements and policies on a short-term or long-term basis. The U.S. and other countries may announce new or changed restrictions with little advance notice. While we are engaged in ongoing efforts to reduce the effect of tariffs, these efforts may take time and be costly to implement and ultimately ineffective. In the event of an expansion of trade restrictions, the imposition of future tariffs on the import of our products or other governmental actions related to tariffs or trade agreements, our business and results of operations may be adversely impacted. 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. 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 19

Our investments in research and development may not yield the results expected. 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 12 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. Investment in new business strategies could disrupt our ongoing business, present risks not originally contemplated and materially adversely affect our business, reputation, results of operations and financial condition. We have invested, and in the future may invest, in new business strategies and restructuring initiatives. Such endeavors may involve significant risks and uncertainties, including distraction of management from current operations, greater-than-expected liabilities and expenses, economic, political, legal and regulatory challenges associated with operating in new businesses, regions or countries, inadequate return on capital, potential impairment of tangible and intangible assets, and significant write-offs. New ventures are inherently risky and may not be successful. The failure of any significant investment or initiative could materially adversely affect our business, reputation, results of operations and financial condition. 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. 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 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 face risks related to the adoption and operations of our redesigned Sonos app. In May 2024, we launched an extensive redesign of our Sonos app and operating system. We did this to provide our customers with a more modern user interface and a modular developer platform that would allow us to deliver new and innovative customer experiences at a faster pace. Following the launch of our redesigned Sonos app, certain of our customers and partners experienced missing features and performance issues, including trouble with set up and general unreliability. These issues with the app have led to increased customer complaints and dissatisfaction, including complaints expressed publicly on social media and elsewhere, and we believe that the app rollout has led to decreased sales of our existing products and reputational harm. Since May 2024, we addressed these issues with software updates to improve performance and add back certain features. Going forward, we intend to prioritize software update releases to optimize and enhance our app. We cannot guarantee that we will be able to release software updates on a cadence or with results that meet the expectations of our customers and partners. Further, the issues resulting from the launch of the redesigned Sonos app, as well as the need to manage challenges associated with maintaining and improving the operations of the app, may result, and have resulted, in impacts to other areas of our business. For example, we delayed the introduction of two new products originally planned for launch in the fourth fiscal quarter of 2024 until October 2024, negatively impacting fourth quarter sales. Moreover, we expect to incur short-term costs of up to $30 million as part of our efforts to improve the app experience and address the concerns of our customers and partners, including increasing customer support staff and taking other measures to engage with and support customers and partners. If the quality and user experience of the Sonos app and related services do not meet the expectations of our customers and partners, or if we cannot successfully address the concerns raised by our customers and partners related the redesigned Sonos app, our operating results, financial condition, customer or partner relationships and reputation may be further adversely impacted. We have incurred operating losses in the past, may incur operating losses in the future, and may not achieve a return to profitability in the future. Although we were profitable in fiscal 2021 and fiscal 2022, we had a net loss of $10.3 million in fiscal 2023 and a net loss of $38.1 million in fiscal 2024. As of September 28, 2024, we had an accumulated deficit of $50.9 million. In order to grow our business, we need to successfully execute on our product roadmap and strategy, which requires that we make ongoing investments, including in research and development efforts to continue to introduce new or enhanced products and services, in our proprietary software, app and operating system, and in sales and marketing efforts to expand our global brand awareness, promote new products, increase our customer base and expand sales within our existing customer base. While we have taken and intend to continue to take actions to moderate operating expenses, these potential efforts and future investments may be more costly than we expect, and we cannot guarantee that we will be able to increase our revenue to offset our operating expenses. Our revenue may decline for a number of reasons, including reduced demand for our products and services, increased competition, and macroeconomic conditions. If our revenue does not grow at a greater rate than our operating expenses, we will not be able to achieve and maintain profitability. If we are unable to accurately anticipate market demand for our products, we may have difficulty managing our production and inventory and our operating results could be harmed. We must forecast production and inventory needs in advance with our suppliers and manufacturers, and our ability to do so accurately could be affected by many factors, including changes in consumer demand and spending patterns, new product introductions, sales promotions, channel inventory levels, and general economic and political conditions. If we fail to accurately forecast consumer demand, we may experience manufacturing delays or inefficiencies, increased costs, excess inventory levels or a shortage of products available for sale, all of which could adversely impact our operating results and financial condition. We have in recent periods experienced, and may continue to experience, a decrease in consumer demand. As a result, we have had to, and may continue to, write-down or write-off inventory or sell the excess inventory at discounted prices, which has, and could in the future, cause our gross margin to suffer. In addition, excess inventory has, and may in the future, result in reduced working capital, which could adversely affect our ability to invest in other important areas of our business such as marketing and product development. If our channel partners have excess inventory of our products, they may decrease their purchases of our products in subsequent periods. In addition, in the event of excess inventory, including excess component inventory, we may be unable to renegotiate our agreements with existing suppliers on mutually acceptable terms. Although in certain instances our agreements with certain suppliers allow us the option to cancel, reschedule, and adjust our requirements based on our business needs, our loss contingencies may include liabilities for contracts that we cannot cancel, reschedule or adjust with suppliers or partners. We may also deem it necessary or advisable to renegotiate agreements with our supply partners in order to scale our inventory with demand.

with one of our contract manufacturers to consolidate and improve supply chain efficiency and our business could be disrupted as a result of this transition. 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. 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, 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 15 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. 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.

•difficulties and associated costs in managing and staffing multiple international locations; and •delays from customs brokers or government agencies. If we are unable to manage the complexity of our global operations successfully, or if the risks above become substantial for us, our financial performance and operating results could suffer. Further, any measures that we may implement to reduce risks of our international operations may not be effective, may increase our expenses and may require significant management time and effort. Our future success will depend in part on our ability to penetrate new international markets where we have limited experience and that require considerable time and financial resources before any significant revenue is generated. There can be no assurance that we will achieve success in these markets. Further, there can be no assurance that the markets we serve and target based on our business strategy will grow in the future, that we will be able to develop any necessary international distribution channels or that our existing and new products will achieve customer acceptance in these markets. Our failure to successfully manage these risks could harm our international operations and our plans for expansion into international markets, and have an adverse effect on our business, financial condition, and operating results. We use AI in our business, and challenges with properly managing its use could result in reputational harm, competitive harm, and legal liability, and adversely affect our results of operations. We have in the past and may in the future incorporate AI, including generative AI, internally for business purposes and into our products and services. These technologies are complex and rapidly evolving and building them requires significant investment in infrastructure and personnel with no assurance that we will realize the desired or anticipated benefits. Our competitors, many of whom have greater technological and financial resources than we do, may more successfully incorporate AI into their products and achieve higher market acceptance of their AI solutions, which could impair our ability to compete effectively and adversely affect our results of operations. Also, if we fail to keep pace with rapidly evolving technological developments in artificial intelligence, our competitive position and business results may suffer. As with many innovations, the use of AI may lead to challenges, concerns and risks that are significant or that we may not be able to predict, especially if our use of these technologies in our products and services becomes more important to our operations over time. For example, our AI-related efforts, particularly those related to generative AI, subject us to risks related to accuracy, intellectual property infringement or misappropriation, data privacy, and cybersecurity, among others. AI solutions, including generative AI, may create output that appears correct but is inaccurate, biased or otherwise flawed, or that infringes or otherwise violates intellectual property or other rights. AI solutions as part of our products or services may not gain acceptance by our customers and may, in the event of inaccurate, biased or flawed output, may lead to customer dissatisfaction. The use of AI may result in cybersecurity incidents that implicate the personal data of users of AI solutions as well as disclosure of our confidential information. Developing, testing and deploying AI systems in a responsible and ethical manner may also increase the cost profile of our products due to the nature of the computing costs and costs to develop or license proprietary datasets and machine learning models involved in such systems. Our business may be disrupted if any of the third-party AI services we use become unavailable due to extended outages or interruptions or because they are no longer available on commercially reasonably terms or prices. Changes to existing regulations, their interpretation or implementation or new regulations could impede our use of AI and also may make it more difficult to operate our business or to protect our intellectual property and may vary jurisdiction from jurisdiction. AI also presents emerging ethical issues, and if our use of AI becomes controversial, we may experience brand or reputational harm, competitive harm, or legal liability. The rapid evolution of AI, including the regulation of AI by government or other regulatory agencies, will require significant resources to develop, test and maintain our platforms, products, and services to implement AI ethically and minimize any unintended harmful impacts. A significant disruption in our websites, servers or information technology systems, or those of our third-party partners, could impair our customers' listening experience or otherwise adversely affect our customers, damage our reputation or harm our business. As a consumer electronics company, our website and mobile app are important presentations of our business, identity and brand and an important means of interacting with, and providing information to, consumers of our products. We depend on our servers and centralized information technology systems, and those of third parties, for product functionality, to manage operations and to store critical information and intellectual property. Accordingly, we allocate significant resources to maintaining our information technology systems and deploying network security, data encryption, training and other measures to protect against unauthorized access or misuse. Nevertheless, our website and information technology systems, and those of the third parties we rely on, are susceptible to damage, viruses, disruptions or shutdowns due to foreseeable and unforeseeable events. System failures and disruptions 17

could impede the manufacturing and shipping of products, functionality of our products, transactions processing and financial reporting, and result in the loss of intellectual property or data, require substantial repair costs and damage our reputation, competitive position, financial condition and results of operations. For example, we use Amazon Web Services ("AWS") to maintain the interconnectivity of our mobile app to our servers and those of the streaming services that our customers access to enjoy our products. Because AWS runs its own platform that we access, we are vulnerable to both system-wide and Sonos-specific service outages at AWS. Our access to AWS' infrastructure could be limited by a number of potential causes, including technical failures, natural disasters, fraud or security attacks that we cannot predict or prevent. Additionally, our products may contain flaws that make them susceptible to unauthorized access or use. For example, we previously discovered a vulnerability in our products that could be exploited when a customer visited a website with malicious content, allowing the customer's local network to be accessed by third parties who could then gain unauthorized access to the customer's playlists and other data and limited control of the customer's devices. While we devote significant resources to address and eliminate flaws and other vulnerabilities in our products, there can be no assurance that our products will not be compromised in the future. Any such flaws or vulnerabilities, whether actual or merely potential, could harm our reputation, competitive position, financial condition and results of operations. Any cybersecurity breaches or our actual or perceived failure to comply with such legal obligations by us, or by our third-party service providers or partners, could harm our business. We collect, store, process and use our customers' personally identifiable information and other data, and we rely on third parties that are not directly under our control to do so as well. While we take measures intended to protect the security, integrity and confidentiality of the personal information and other sensitive information we collect, store or transmit, we cannot guarantee that inadvertent or unauthorized use or disclosure will not occur, or that third parties will not gain unauthorized access to this information. There have been a number of recent reported incidents where third parties have used software to access the personal data of their partners' customers for marketing and other purposes. If we or our third-party service providers were to experience a breach, disruption or failure of systems compromising our customers' data, or if one of our third-party service providers or partners were to access our customers' personal data without our authorization, our brand and reputation could be adversely affected, use of our products could decrease and we could be exposed to a risk of loss, litigation and regulatory proceedings. In addition, a breach could require expending significant additional resources related to the security of information systems and disrupt our operations. The use of data by our business and our business associates is highly regulated in all our operating countries. Privacy and information security laws and regulations change, and compliance with them may result in cost increases due to, among other things, systems changes and the development of new processes. If we or those with whom we share information fail to comply with laws and regulations, such as the General Data Protection Regulation ("GDPR") and California Consumer Privacy Act ("CCPA"), our reputation could be damaged, possibly resulting in lost business, and we could be subjected to additional legal risk or financial losses as a result of non-compliance. Complying with such laws may also require us to modify our data processing practices and policies and incur substantial expenditures.

We may need additional capital, and we cannot be certain that additional financing will be available. We are parties to a credit agreement with JPMorgan Chase Bank, N.A., KeyBank National Association and Goldman Sachs Bank USA, which allows us to borrow up to $80.0 million, with a maturity date of October 2030. 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 21 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 and brands Harman International, Denon, Polk Audio and Bowers and Wilkens, and JBL), Sony, Bang & Olufsen, Sennheiser, Apple, Google, and Amazon. 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.

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 Vietnam, China and Malaysia. We have continued to maintain diversified contract manufacturing partnerships with more of our production in Malaysia and Vietnam. During the third quarter of fiscal 2025, we began the process of exiting a partnership with one of our contract manufacturers to consolidate and improve supply chain efficiency. We expect to complete this exit with minimal disruption to our business during fiscal 2026. 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. As of September 27, 2025, our open purchase orders to contract manufacturers for finished goods were approximately $173 million, the majority of which are expected to be paid within the next six months. As of September 27, 2025, our expected commitments to suppliers for components were in the range of $131 million to $149 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 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 North America, Australia, Europe, and Asia. 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.

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. Diversity, Equity and Inclusion. At Sonos, we believe that music and sound is universal and connects us as people, and we strive to build products that move everyone. To do this, we are committed to building an equitable and inclusive environment where diverse teams build more creative solutions, drive better results, innovate and bring their authentic selves to work each day. 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;

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, as well as automotive sound.

Sales and Marketing Our products are distributed in more than 60 countries through retailer's traditional physical stores and their websites, online retailers, custom installers who bundle our products with their services, and directly through our website sonos.com. Our marketing investments are focused on increasing brand awareness through advertising, public relations, and brand promotion activities, including digital platforms, sponsorships, collaborations, brand activations, and channel marketing. We also invest in product displays to support our retail channel partners. While we maintain a base level of investment throughout the year, significant increases in spending have historically been highly correlated with the holiday shopping season, and new product launches. We intend to continue to invest in our marketing and brand development efforts. 7
