PART I
Item 1: Business

Overview

Sonos is one of the world's leading sound experience brands. As the inventor of multi-room wireless audio products, Sonos' innovation helps the world listen better by giving people access to the content they love and allowing them to control it however they choose. Known for delivering an unparalleled sound experience, thoughtful design aesthetic, simplicity of use and an open platform, Sonos makes a breadth of audio content available to anyone.

Our sound system provides an immersive listening experience created by our thoughtfully designed speakers and components, our proprietary software platform and the ability to wirelessly stream the content our customers love from the services they prefer. We manage the complexity of delivering a seamless customer experience in a multi-user and open-platform environment. The Sonos sound system is easy to set up, use, and expand to bring audio to any room in the home. Through our software platform, we frequently enhance features and services on our products, improving functionality and customer experience.

Sonos sits at the intersection of emerging consumer technology and entertainment trends. The proliferation of streaming services and the rapid adoption of voice assistants are significantly changing audio consumption habits and how consumers interact with the internet. As a leading sound system for consumers, content partners and developers, Sonos is capitalizing on the large market opportunity created by these dynamics. Our network of partners provides our customers with access to voice control, streaming music, internet radio, podcasts and audiobook content, enabling them to control and listen to an expansive range of audio entertainment. Our platform has attracted a broad range of approximately 100 streaming content providers, such as Apple Music, Pandora, Spotify, and TuneIn. These partners find value in our independent platform and access to our millions of desirable and engaged customers.

We debuted the world’s first multi-room wireless sound system in 2005 and have since been a leading innovator in wireless home audio. Today, our products include wireless, portable, and home theater speakers, components, and accessories to address consumers’ evolving audio needs. In addition, 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 evidenced by our growing global patent portfolio. We believe our patents comprise the foundational intellectual property for wireless multi-room and other audio technologies.

As of October 2, 2021, we had a total of nearly 37.1 million products registered in approximately 12.6 million households globally, including the addition of approximately 1.7 million new households during fiscal 2021. Our customers have typically purchased additional Sonos products over time. As of October 2, 2021, 60% of our 12.6 million households had registered more than one Sonos product. As of October 2, 2021, our households own 3.0 products on average. We also estimate that our customers listened to 12.1 billion hours, excluding Bluetooth listening, of audio content using our products in fiscal 2021, which represents 19.0% growth from fiscal 2020.

Our innovative products, seamless customer experience, and expanding global footprint have driven 16 consecutive years of sustained revenue growth since our first product launch. We generate revenue from the sale of our Sonos speaker products, including wireless speakers and home theater speakers, from our Sonos system products, which largely comprises our component products, and from partner products and other revenue, including partnerships with IKEA and Sonance, Sonos and third-party accessories, licensing, advertising, and subscription revenue.

Our growth is driven by both new customers buying our products as well as existing customers continuing to add products to their Sonos systems. In fiscal 2021, existing customers accounted for approximately 46% of new product registrations. We sell our products primarily through over 10,000 third-party physical retail stores, including custom installers of home audio systems. We also sell through select e-commerce retailers and our website sonos.com. Our products are distributed in over 50 countries, with 48.1% of our revenue in fiscal 2021 generated outside the United States.

Our Software

Our proprietary software is the foundation of the Sonos sound system and further differentiates our products and services from those of our competitors.

In June 2020, we introduced Sonos S2, a powerful new app and operating system to enable a new generation of Sonos products and experiences, which includes new features, usability updates, and more personalization while also enabling higher resolution audio technologies for music and home theater.

Our software provides the following key benefits:

Multi-room 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.

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. We have made significant investments in our engineering team and audio technology. For example, we invented technology to allow two or more of our speakers to pair wirelessly and create multi-channel sound, thereby enabling a much broader sound field. In addition, our Trueplay technology utilizes the microphones on an iOS device to analyze room attributes, speaker placement and other acoustic factors in order 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.

Continuous Improvement. Our software platform and cloud service enables feature enhancements and delivery of new experiences on an ongoing basis, so the Sonos experience improves for customers over time.

Our Partner Ecosystem

We have built a platform that attracts partners to enable our customers to play content from their preferred services. Our partners span 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 voice-enabled speaker products have Amazon Alexa and Google Assistant functionality, making our platform the first to offer consumers the ability to buy a single smart speaker with more than one voice assistant choice.
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, as well as picture frames, bookshelf speaker and table lamp speaker in partnership with IKEA, and automotive sound partnership with Audi.
Our Competitive Strengths

We believe the following combination of capabilities and features of our business model distinguish us from our competitors and position us well to capitalize on our opportunities:

Leading sound system. We have developed and refined our sound system over the last 18 years. Our effort has resulted in significant consumer awareness and market share among home audio professionals. For example, a 2021 product study by CE Pro ranked Sonos as the leading brand in the wireless speakers, soundbar, and subwoofer categories. Our 92% share in the wireless speakers category among these industry professionals significantly outpaces our competitors.

Proprietary Sonos app and software platform. We offer our customers a mobile app that controls the Sonos sound system and the entire listening experience. Customers can stream different audio content to speakers in different rooms or the same audio content synchronized throughout the entire home. Additionally, the Sonos app enables universal search, the ability to search for audio content across streaming services and owned content to easily find, play or curate music.
Platform enables freedom of choice for consumers. Our broad and growing network of partners provides our customers with access to voice control, streaming music, internet radio, podcasts and audiobook content, enabling them to listen to the content they love from the services they prefer. Our platform attracts a broad set of content providers, including leading streaming music services and third-party developers.
Differentiated consumer experience creates engaged households who often repeat purchases. We deliver a differentiated customer experience to millions of households every day, cultivating a passionate and engaged customer base. Long-term engagement with our products and our ability to continuously improve the functionality of our existing products through software updates leads to attractive economics as customers add products to their Sonos sound systems. We generate significant revenue and profits from customers purchasing additional products to expand their Sonos sound systems. Existing households represented approximately 46% of new product registrations in fiscal 2021. We have proven our ability to profitably add new homes, and develop new experiences that drive existing customers to add additional products to their home. We believe that we have yet to fully realize the lifetime value of our customer base. We believe this aspect of our financial model will continue to contribute to our ability to achieve sustainable, profitable growth over the long term.
Commitment to innovation drives continuous improvement. We have made significant investments in research and development since our inception and believe that we own the foundational intellectual property of wireless multi-room and other audio technologies. We have significantly expanded the size of our patent portfolio in recent years. In 2019, the strength of our patent portfolio placed us 3rd in Electronics in the 1790 Analytics Patent Scorecards study.

Our Growth Strategies

Key elements of our growth strategy include:

Continued introduction of innovative products and services and expansion into new categories. To address our market opportunity, we have developed a long-term roadmap to deliver innovative products, services and software enhancements, and expand into new categories. We intend to continue to introduce products and services across multiple categories designed for enjoyment in all the places and spaces that our customers listen to audio content, including outside of the home, as well as business and enterprise customers. Executing on our roadmap will position us to acquire new customers, increase sales to existing customers, and improve the customer experience.
Expansion of direct-to-consumer efforts and building relationships with existing channel partners and prospective customers. We are focused on reaching and converting prospective customers through third-party retail stores, e-commerce retailers, custom installers of home audio systems, and our website sonos.com. We expect that our direct-to-consumer channel will continue to contribute to our growth. We intend to continue to build direct relationships with current and prospective customers through sonos.com and the Sonos app to drive direct sales. In fiscal 2021, we generated 24.2% of total revenue through our direct-to-consumer channel, primarily sonos.com. While we seek to increase sales through our direct-to-consumer sales channel, we expect that our third-party retailers will continue to be an important part of our ecosystem. We will continue to seek retail partners that can deliver differentiated in-store experiences to support customer demand for product demonstrations. Additionally, we intend to expand and strengthen our partnerships with custom installers who are valuable to our customer base and contribute to our new household growth. For example, a 2021 product survey by CE Pro ranked Sonos as the leading brand in the wireless speakers, soundbar, and subwoofer categories. Our 92% share in the wireless speakers among these industry professionals significantly outpaces our competitors.
Expand partner ecosystem to enhance platform. We intend to deepen our relationships with our current partners and expand our partner ecosystem by providing our customers access to streaming music services, voice assistants, internet radio, podcasts and audiobook content.

Increase brand awareness in existing geographic markets. We intend to increase our household penetration rates in our existing geographic markets by increasing brand awareness, expanding our product offerings and growing our partner ecosystem.
Expansion into new geographic markets. Geographic expansion represents a growth opportunity in currently underserved countries. We intend to expand into new countries over time by employing country-specific marketing campaigns and distribution channels.
Research and Development

Our research and development team develops new software and hardware products and services, as well as improves and enhances our existing software and hardware products to address customer demands and emerging trends. Our team has worked on features and enhancements to the Sonos system including development and improvements to the Sonos app, product setup, Trueplay tuning, and the ability to use Alexa or Google voice services. Our audio team has developed a series of acoustic technologies which enabled us to create speakers that produce high-fidelity sound. Our wireless and radio team established world-class wireless performance that enabled multi-room experience, wireless surround sound, and many more applications. Our industrial design and mechanical engineering teams developed a cohesive, unique family of products across multiple categories and use-cases such as home theater, all-in-one, and portable. These products demonstrate a range of proprietary manufacturing and design details, logo application techniques, and assembly architecture. The products and software we develop require significant technological knowledge and expertise to develop at a competitive pace. We believe our research and development capabilities and our intellectual property differentiates us from our competitors. We intend to continue to significantly invest in research and development to bring new products and software to market and expand our platform and capabilities.

Sales and Marketing

We sell our products primarily through over 10,000 third-party physical retail stores, including custom installers of home audio systems, and our products are distributed in more than 50 countries. The majority of our sales are transacted through traditional physical retailers, including on their websites. We also sell through online retailers, to custom installers who bundle our products with services that they sell to their customers, and directly through our website sonos.com. We sell products internationally through distributors and through retailers.

We invest in customer experience and customer relationship management to drive loyalty, word-of-mouth marketing and growth of our direct channels. Our marketing investments are focused on driving profitable growth through advertising, public relations and brand promotion activities, including digital, sponsorships, brand activations and collaborations, and channel marketing. We intend to continue to invest significant resources in our marketing and brand development efforts, including investing in capital expenditures on product displays to support our retail channel partners.

Manufacturing, Logistics and Fulfillment

We outsource the manufacturing of our speakers and components to contract manufacturers, using our design specifications. Our products are manufactured by contract manufacturers in China and during fiscal 2020, we began to diversify our supply chain through the addition of contract manufacturing in Malaysia. The COVID-19 pandemic has affected our supply chain consistent with its effect across many industries, including creating shipping and logistics challenges, and placing significant limits on component supplies. The pandemic has also delayed our efforts to fully diversify our supply chain into Malaysia until fiscal 2022.

Our contracts with our contract manufacturers do not obligate them to supply products to us in any specific quantity, except as specified in our purchase orders that are aligned with forecasts based on terms and conditions of the contract. The vast majority of our products are shipped to our third-party warehouses which we then ship 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.

Competition

We compete against established, audio-focused sellers of speakers and sound systems such as Bang & Olufsen, Bose, Samsung (and its subsidiaries Harman International and JBL), Sony and Sound United (and its subsidiaries Denon and Polk), and against developers of voice-enabled speakers and other voice-enabled products such as Amazon, Apple and Google. In some cases, our competitors are also our partners in our product development and resale and distribution channels. Many of our competitors have significant market share, diversified product lines, well-established supply and distribution systems, strong worldwide brand recognition, loyal customer bases and significant financial, marketing, research, development and other resources.

The principal competitive factors in our market include:

brand awareness and reputation;
breadth of product offering;
price;
sound quality;
multi-room and wireless capabilities;
customer support;
product quality and design;
ease of setup and use; and
network of technology and content partners.

We believe we compete favorably with our competitors on the basis of the factors described above.

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, we filed a complaint with the U.S. International Trade Commission ("ITC") against Alphabet Inc. ("Alphabet") and Google LLC ("Google") and a lawsuit in the U.S. District Court for the Central District of California against Google. The complaint and lawsuit each allege infringement of certain Sonos patents related to its smart speakers and related technology. In September 2020, we filed a lawsuit against Google in the U.S. District Court for Western District of Texas, alleging infringement of five Sonos wireless audio patents, which lawsuit has been subsequently transferred to the U.S. District Court for the Northern District of California. In December 2020, we filed a lawsuit against Google Germany Gmbh and Google Ireland Ltd. in the regional court of Hamburg, Germany, alleging infringement of a Sonos patent related to control of playback of media by mobile and playback devices. Google has responded by filing a patent infringement lawsuit and a declaratory judgement of non-infringement against us during fiscal 2020 in the U.S. District Court for the Northern District of California and in Canada, Germany, France and the Netherlands, and patent infringement lawsuits against our subsidiary Sonos Europe B.V. in Germany, France and the Netherlands. See 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.

While we believe that our active patents and patent applications are an important aspect of our business, we also rely heavily on the innovative skills, technical competence and marketing abilities of our personnel.

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 experienced 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 October 2, 2021, we had 1,525 full-time employees. Of our full-time employees, 1,075 were in the United States and 450 were in our international locations. Other than our employees in France and the Netherlands, none of our employees are represented by a labor union or covered by a collective bargaining agreement.

Table of contents
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, annual 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.

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 Investor Relations section of our website.
In fiscal 2020, we set a goal of 50% of new U.S. hires coming from underrepresented groups. In fiscal 2021, we made progress towards this goal, with 44% of new U.S. hires from underrepresented groups. 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:

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;
coupling our hiring goals with a focus on retention, employee engagement, and inclusive leadership;

Item 1A. Risk Factors

Investing in our common stock involves a high degree of risk. You should carefully consider the risks and uncertainties described below, as well as the other information in this Annual Report on Form 10-K, including our consolidated financial statements and the related notes, and the section titled “Management’s Discussion and Analysis of Financial Condition and Results of Operations,” before making an investment decision. The occurrence of any of the events or developments described below could materially and adversely affect our business, financial condition, results of operations and growth prospects. In such an event, the market price of our common stock could decline, and you may lose all or part of your investment. Additional risks and uncertainties not currently known to us or that we currently believe are not material may also impair our business, financial condition, results of operations and growth prospects.

Economic, Industry and Strategic Risk

Our business has been, and could in the future be, adversely affected by the ongoing COVID-19 pandemic.

In December 2019, COVID-19 was reported in China and subsequently was declared a global pandemic in March 2020 by the World Health Organization. To date, COVID-19 and related preventative and mitigation measures have negatively impacted the global economy, disrupted consumer spending and global supply chains, and created significant volatility and disruption of financial markets.

Our fiscal 2021 business and operating results were affected by the COVID-19 pandemic as a result of the temporary closure of some of the retail stores in our end-markets at various times during fiscal 2021. Although retail stores have reopened and restrictions eased in more end-markets recently, and we have seen a corresponding return of retail demand, in the event of a COVID-19 resurgence, retail stores in an affected end-market may reinstitute operational restrictions or temporary closures, which may impact consumer retail purchasing behavior in that end-market.

The COVID-19 pandemic has also adversely affected our supply chain, consistent with its effect across many industries, including creating shipping and logistics challenges and placing significant limits on component supplies. These effects on our supply chain have resulted in delayed product availability, especially when combined with the increased demand for our products, and have adversely impacted, and may continue to adversely impact, our ability to meet our product demand, result in additional costs, result in customer dissatisfaction in the event of continued inventory shortages, or may otherwise adversely impact our business and results of operations. See "We depend on a limited number of third-party components suppliers and logistics providers" in this Item 1A. Risk Factors, for more information. The pandemic has also delayed our efforts to fully diversify our supply chain into Malaysia until fiscal 2022. We expect these impacts, including delayed product availability, to continue for as long as the global supply chain is experiencing these challenges.

COVID-19 has negatively impacted the global economy to date and is likely to cause further global economic disruption. While the duration and severity of the economic impacts of COVID-19 are unknown, it is possible that such economic impacts may be prolonged and have continued effects even after the widespread administration of vaccines. In particular, any recession, depression, or other sustained adverse market event resulting from COVID-19 may result in high levels of unemployment and associated loss of personal income, decreased consumer confidence, and lower discretionary spending, which could materially and adversely affect our business, results of operations, financial position and cash flows.

The extent of the impact of the COVID-19 pandemic on our business and operating results is uncertain and difficult to predict and will depend on factors outside of our control including the timing or effectiveness of the vaccine roll-out globally, the timing of easing of preventative or mitigation measures or mandates, the impact of any variants that emerge, or any impact of a global vaccine roll-out on the global economy, our business or our suppliers. Moreover, we have experienced increased demand for our products during the COVID-19 pandemic and we cannot predict how or whether the easing of COVID-19 preventative or mitigation measures or mandates will impact demand for our products or shift consumer spending habits in general.

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 speakers and sound systems such as Bang & Olufsen, Bose, Samsung (and its subsidiaries Harman International and JBL), Sony and Sound United (and its subsidiaries Denon and Polk), and developers of voice-enabled speakers and systems such as Amazon, Apple and Google. We could also face competition from new market entrants, some of whom might be current partners of ours.

In order to deliver products that appeal to changing and increasingly diverse consumer preferences and to 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, we must develop superior technology, anticipate increasingly diverse consumer tastes and rapidly develop attractive products with competitive selling prices. In addition, many of our current and potential partners have business objectives that may drive them to sell their speaker products at a significant discount compared to ours. Amazon and Google, for example, both currently offer their speaker products at significantly lower prices than Sonos One, Sonos Beam, Sonos Arc, Sonos Roam and Sonos Move. Many of these partners may subsidize these prices and seek to monetize their customers through the sale of additional services rather than the speakers themselves. Even if we are able to efficiently develop and offer innovative products 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 consumer products or if the average selling prices of our products decrease faster than we are able to reduce our manufacturing costs.

Most of our competitors have greater financial, technical and marketing resources available to them than those available to us, and, as a result, they may develop competing products that cause the demand for our products to decline. 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 acquire companies that will allow them to develop products that better compete with our products, which would intensify the competition that we face and may also disrupt or lead to termination of our distribution, technology and content partnerships. 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.

To remain competitive and stimulate consumer demand, we must successfully manage frequent new product introductions and transitions.

Due to the quickly evolving and highly competitive nature of the home audio and broader consumer electronics industry, we must frequently introduce new products, enhance existing products and effectively stimulate customer demand for new and upgraded products in both mature and developing markets. For example, in June 2020, we introduced Arc, our premium smart soundbar, Five and the next generation of our Sub, in November 2020, we introduced Radio HD, our ad-free high-definition streaming tier of our radio service, and, in April 2021, we introduced Roam, our portable smart speaker. The successful introduction of these products and any new products depends on a number of factors, such as the timely completion of development efforts to correspond with limited windows for market introduction. We face significant challenges in managing the risks associated with new product introductions and production ramp-up issues, including accurately forecasting initial consumer demand, effectively managing any third-party strategic alliances or collaborative partnerships related to new product development or commercialization, as well as the risk that new products may have quality or other defects in the early stages of introduction or may not achieve the market acceptance necessary to generate sufficient revenue. New and upgraded products can also affect the sales and profitability of existing products. Accordingly, if we cannot properly manage the introduction of new products, our operating results and financial condition may be adversely impacted, particularly if the cadence of new product introductions increases as we expect.

Table of contents
We have a history of losses and expect to incur increased operating costs in the future, and we may not sustain profitability or consistent revenue growth.

We have experienced net losses in our previous annual periods. In the fiscal years ended October 3, 2020, and September 28, 2019, we had net losses of $20.1 million and $4.8 million, respectively. We had an accumulated deficit of $69.9 million as of October 2, 2021. We expect our operating expenses to increase in the future as we expand our operations and execute on our product roadmap and strategy. We plan to make significant future expenditures related to the expansion of our business and our product offerings, including investments in:
research and development to continue to introduce innovative new products, enhance existing products and improve our customers’ listening experience;
sales and marketing to expand our global brand awareness, promote new products, increase our customer base and expand sales within our existing customer base; and
legal, accounting, information technology and other administrative expenses to sustain our operations as a public company.

We need to increase our revenue to maintain profitability in the future and we cannot assure you that we will be able to increase our revenue, particularly in a global recession or depression. For example, the COVID-19 pandemic and related disruptions and uncertainties in the global economy and in consumer spending had certain adverse impacts on our revenue in fiscal 2020 and fiscal 2021. Our ability to achieve revenue growth will depend in part on our ability to execute on our product roadmap and our strategy and to determine the market opportunity for new products. New product introductions may adversely impact our gross margin in the near to intermediate term due to the frequency of these product introductions and their anticipated increased share of our overall product volume. The expansion of our business and product offerings also places a continuous and significant strain on our management, operational and financial resources. In the event that we are unable to grow our revenue, or in the event that revenue grows more slowly than we expect, our operating results could be adversely affected and our stock price could be harmed.

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 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. 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 future growth relies, in part, on our continued ability to attract consumers to this channel, which has and will 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, our business and results of operations could be harmed, particularly during the COVID-19 pandemic during which physical retail stores may be closed or significantly modify their retail experience. 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 may have an adverse impact on our results of operations.

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; our ability to do so accurately could be affected by many factors, including changes in customer demand, new product introductions, sales promotions, channel inventory levels, uncertainty related to the duration and impact of COVID-19, and general economic conditions. If demand does not meet our forecast, excess product inventory could force us to write-down or write-off inventory or to sell the excess inventory at discounted prices, which could cause our gross margin to suffer and impair the strength of our brand. In addition, excess inventory may 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
15

Table of contents
inventory of our products, they may decrease their purchases of our products in subsequent periods. If demand exceeds our forecast, as it did in parts of fiscal 2020 and fiscal 2021, and we do not have sufficient inventory to meet this demand, we may experience decreased revenue or customer dissatisfaction as a result of any continued inventory shortages or we may have to rapidly increase production which may result in reduced manufacturing quality and customer satisfaction as well as higher supply and manufacturing costs that would lower our gross margin. Any of these scenarios could adversely impact our operating results and financial condition.

Our efforts to expand beyond our core product offerings and offer products with applications outside the home may not succeed and could adversely impact our business.

We may seek to expand beyond our core sound systems and develop products that have wider applications outside the home, such as commercial or office. Developing these products would require us to devote substantial additional resources, and our ability to succeed in developing such products to address such markets 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 may have less familiarity with consumer preferences for these products and less product or category knowledge, and we could encounter difficulties in attracting new customers due to lower levels of consumer familiarity with our brand. 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 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.

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.

Given the seasonal nature of our sales, accurate forecasting is critical to our business. Our fiscal year ends on the Saturday closest to September 30, the holiday shopping season occurs in the first quarter of our fiscal year and the typically slower summer months occur in the fourth quarter of our fiscal year. Historically, our revenue has been significantly higher in our first fiscal quarter due to increased consumer spending patterns during the holiday season. Any shortfalls in expected first fiscal quarter revenue, due to macroeconomic conditions, product release patterns, a decline in the effectiveness of our promotional activities, supply chain disruptions or for any other reason, 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.

The success of our business depends in part on the continued growth of the voice-enabled speaker market and our ability to establish and maintain market share.

We have increasingly focused our product roadmap on voice-enabled speakers. We introduced our first voice-enabled speaker, Sonos One, in October 2017, our first voice-enabled home theater speaker, Sonos Beam, in July 2018, our first Bluetooth-enabled portable speaker with voice control, Sonos Move, in September 2019 and our voice-enabled premium home theater speaker, Sonos Arc, in June 2020. In April 2021, we introduced Roam, our portable smart speaker. If the voice-enabled speaker markets do not continue to grow or grow in unpredictable ways, our revenue may fall short of expectations and our operating results may be harmed, particularly since we incur substantial costs to introduce new products in advance of anticipated sales. Additionally, even if the market for voice-enabled speakers does continue to grow, we may not be successful in developing and selling speakers that appeal to consumers or gain sufficient market acceptance. To succeed in this market, we will need to design, produce and sell innovative and compelling products and partner with other businesses that enable us to capitalize on new technologies, some of which have developed or may develop and sell voice-enabled speaker products of their own as further described herein.

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 proportion 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 significant 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, Pandora, Spotify and TuneIn. 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.

We rely and expect to continue to rely on a combination of confidentiality and license agreements with our employees, consultants and third parties with whom we have relationships, as well as patent, trademark, copyright and trade secret protection laws, to protect our proprietary rights. 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, pending and future patent and trademark applications may not be approved, and we may not be able to prevent infringement 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, on January 7, 2020, we filed a complaint with the U.S. International Trade Commission against Alphabet and Google and a lawsuit in the U.S. District Court for the Central District of California against Google, alleging patent infringement of certain Sonos patents related to our smart speakers and related technology. In addition, on September 29, 2020, we filed a lawsuit against Google in the U.S. District Court for Western District of Texas, subsequently transferred to the Northern District of California, alleging infringement of five Sonos wireless audio patents, and, in December 2020, we filed a lawsuit against Google Germany Gmbh and Google Ireland Ltd. in the regional court of Hamburg, Germany, alleging infringement of a Sonos patent related to control of playback of media by mobile and playback devices. The cost of defending our intellectual property has 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. 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. As our brand grows, we may 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. As we gain an increasingly high profile and face more intense competition in our markets, and as we 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 is 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 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. Any damage to our brand or reputation may adversely affect our business, financial condition and operating results.

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. We introduced Sonos One, Sonos Beam, Sonos Move, Sonos Roam, and Sonos Arc, which feature built in voice-enabled speakers powered by Amazon’s Alexa or Google’s Google Assistant technology. One or more of our partners could disable their integration, 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
18

Table of contents
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.

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 (“Inventec”), manufacturing a majority of our products. We have also historically manufactured our products in China and in early fiscal 2020 began to diversify our supply chain through the addition of contract manufacturing in Malaysia. Our reliance on a limited number of contract manufacturers increases the risk that, in the event that any or all of such manufacturers experience an interruption in their operations, fail to perform their obligation in a timely manner or terminate agreements with us, we would not be able to maintain our production capacity without incurring material additional costs and substantial delays or we may be fully prevented from selling our products. 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.

In addition, there is no guarantee that our efforts to diversify manufacturers will be successful. Identifying and onboarding a new manufacturer takes a significant amount of time and resources. If we do not successfully coordinate the timely manufacturing and distribution of our products by such manufacturers, if such manufacturers are unable to successfully and timely process our orders or if we do not receive timely and accurate information from such manufacturers, we may have an insufficient supply of products to meet customer demand, we may lose sales, we may experience a build-up in inventory, we may incur additional costs, and our financial performance and reporting may be adversely affected. By adding manufacturers in other countries, we may experience increased transportation costs, fuel costs, labor unrest, impact of natural disasters and other adverse effects on our ability, timing and cost of delivering products, which may increase our inventory, decrease our margins, adversely affect our relationships with distributors and other customers and otherwise adversely affect our operating results and financial condition. In addition, any partial or full government-mandated shutdown resulting from COVID-19 has delayed and may further delay our efforts to diversify our supply chain or may cause supply chain disruptions notwithstanding any supply chain diversification efforts.

We depend on a limited number of third-party components suppliers and logistics providers.

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, which risk has been and may continue to be increased by the impact of COVID-19. 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.

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 as a result of COVID-19, 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, including COVID-19 shutdowns. 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.

During the fourth quarter of fiscal 2020 and through fiscal 2021, the pandemic affected our supply chain, consistent with its effect across many industries, and we saw certain constraints on the ability of our component suppliers and logistics providers to timely meet commitments, including significant limits on component supplies, primarily semiconductors, and port
19

Table of contents
congestion, which has, and may continue to, adversely impact our ability to meet our product demand, result in additional costs, or may otherwise adversely impact our business and results of operations. These challenges have also delayed our efforts to fully diversify our supply chain into Malaysia until fiscal 2022. We expect these impacts to continue for as long as the global supply chain continues to experience these challenges.

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 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 14% of our revenue in fiscal 2021. 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. As a result of the COVID-19 pandemic, many of our key channel partners have temporarily closed or reduced operations in their retail stores at various times during fiscal 2021 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 store closures due to the COVID-19 pandemic, 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. We previously announced that certain legacy products will continue to work but will no longer receive software updates (other than bug fixes and patches) beginning in May 2020. 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.

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
20

Table of contents
product could be delayed until we remedy 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 two-year warranty on all our products. 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 we expect to continue to expand our international presence, especially in Asia. In fiscal 2021, 48.1% 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, including related to the ongoing COVID-19 pandemic and the United Kingdom's withdrawal from the EU, commonly known as "Brexit"
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;
difficulties and associated costs in managing 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. Entry into new international markets requires considerable management time and financial resources related to market, personnel and facilities development before any significant revenue is generated. As a result, initial operations in a new market may operate at low margins or may be unprofitable.

We have significant operations in China, where many of the risks listed above are particularly acute. China experiences high turnover of direct labor due to the intensely competitive and fluid market for labor, and if our labor turnover rates are higher than we expect, or we otherwise fail to adequately manage our labor needs, then our business and results of operations could be adversely affected.

We will need to improve our financial and operational systems to manage our growth effectively and support our increasingly complex business arrangements, and an inability to do so could harm our business and results of operations.

To manage our growth and our increasingly complex business operations, especially as we move into new markets internationally, we will need to upgrade our operational and financial systems and procedures, which requires management time and may result in significant additional expense. In particular, beginning in fiscal 2020 and continuing through fiscal 2021, we began activities to replace our legacy enterprise resource management system in order to accommodate our expanding operations. We cannot be certain that we will institute, in a timely or efficient manner or at all, the improvements to our managerial, operational and financial systems and procedures necessary to support our anticipated increased levels of operations. Problems associated with, or disruptions resulting from, any improvement or expansion of our operational and
21

Table of contents
financial systems could adversely affect our relationships with our suppliers, manufacturers, resellers and customers, inhibit our ability to expand or take advantage of market opportunities, cause harm to our reputation, result in errors in our financial and other reporting and affect our ability to maintain an effective internal control environment and meet our external reporting obligations, any of which could harm our business and operating results and affect our stock price.

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 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.

Changes in how network operators manage data that travels across their networks or in net neutrality rules could harm our business.

We rely upon the ability of consumers to access our service through the internet. If network operators block, restrict or otherwise impair access to our service over their networks, our service and business could be negatively affected. To the extent that network operators implement usage-based pricing, including meaningful bandwidth caps, or otherwise try to monetize access to their networks by data providers, we could incur greater operating expenses. Furthermore, to the extent network operators create tiers of internet access service and either charge us for or prohibit us from being available through these tiers, our business could be negatively impacted.

Further, in the past, internet service providers ("ISPs") have attempted to implement usage-based pricing, bandwidth caps and traffic shaping or throttling. To the extent network operators create tiers of internet access service and charge our customers in direct relation to their consumption of audio content, our ability to attract and retain customers could be impaired, which would harm our business. Net neutrality rules, which were designed to ensure that all online content is treated the same by ISPs and other companies that provide broadband services, were repealed by the Federal Communications Commission ("FCC") effective June 2018. Although the FCC has preempted state jurisdiction on net neutrality, some states have taken executive action directed at reinstating aspects of the FCC’s 2015 order. Further, while many countries, including across the EU, have implemented net neutrality rules, in others, the laws may be nascent or non-existent. The absence or repeal of the net neutrality rules could force us to incur greater operating expenses, cause our streaming partners to seek to shift costs to us or result in a decrease in the streaming-based usage of our platform by our customers, any of which would harm our results of operations. In addition, given uncertainty around these rules, including changing interpretations, amendments or repeal, coupled with potentially significant political and economic power of local network operators, we could experience discriminatory or anti-competitive practices that could impede our growth, cause us to incur additional expense or otherwise negatively affect our business.

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.

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.

Under the previous administration, the U.S. government has imposed significant new 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"), which Section 301 tariffs have 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 for a period of time during fiscal 2020 and, for our core speaker products, through the first quarter of fiscal 2021 but all exemptions which we were granted expired on December 31, 2020. To date, we have been able to obtain refunds on tariffs paid during the exemption periods and continue to see outstanding refund requests and corresponding refunds processed.

In the event that future tariffs are imposed on imports of our products, we do not successfully obtain the remaining refunds to which we are currently entitled, we are not successful in any future exemption requests, the amounts of existing tariffs are increased, we experience prolonged COVID-19 shutdowns in Malaysia, our supply chain diversification efforts are further delayed or China, or other countries take retaliatory trade measures in response to existing or future tariffs, 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. In response to the Section 301 tariffs (among other factors), in early fiscal 2020 we began to
23

Table of contents
diversify our supply chain through the addition of contract manufacturing in Malaysia. In response to future new tariffs, we may further shift production outside of China, resulting in significant costs and disruption to our operations as we would need to pursue the time-consuming processes of recreating new supply chains, identifying substitute components and establishing new manufacturing locations.

We must comply with extensive regulatory requirements, and the cost of such compliance, and any 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 profits, cash flow and effective tax rate 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 October 2, 2021, we had gross U.S. federal net operating loss carryforwards of $101.4 million, of which $70.3 million have an indefinite life and $31.1 million that expire beginning in 2035, and gross state net operating loss carryforwards of $64.6 million, which expire beginning in 2027, as well as $53.3 million in foreign net operating loss carryforwards with an indefinite life. As of October 2, 2021, we also had U.S. federal research and development tax credit carryforwards of $62.0 million, and state research and development tax credit carryforwards of $44.3 million, which will expire beginning in 2025 and 2024, 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. Since shares of our common stock were sold in our IPO in August 2018 at a price of $15.00 per share, the closing price of our common stock has ranged from $6.97 to $43.89 through October 2, 2021. 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 initiate or 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 newly public companies, particularly 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.

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
25

Table of contents
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.

General Risk Factors

The loss of one or more of our key personnel, or our failure to attract, assimilate and retain other highly qualified personnel in the future, could harm our business.

We depend on the continued services and performance of our key personnel. The loss of key personnel, including key members of management as well as our product development, marketing, sales and technology personnel, could disrupt our operations and have an adverse effect on our ability to grow our business. In addition, the loss of key personnel in our finance and accounting departments could harm our internal controls, financial reporting capability and capacity to forecast and plan for future growth. Further, the market for highly skilled workers and leaders in our industry is extremely competitive. If we do not succeed in attracting, hiring and integrating high-quality personnel or in retaining and motivating existing personnel, we may be unable to grow effectively, and our financial condition may be harmed.

Natural disasters, geopolitical unrest, war, terrorism, pandemics, public health issues or other catastrophic events could disrupt the supply, delivery or demand of products, which could negatively affect our operations and performance.

We are subject to the risk of disruption by earthquakes, floods and other natural disasters, fire, power shortages, geopolitical unrest, war, terrorist attacks and other hostile acts, public health issues, epidemics or pandemics, including COVID-19, and other events beyond our control and the control of the third parties on which we depend. Any of these catastrophic events, whether in the United States or abroad, may have a strong negative impact on the global economy, us, our contract manufacturers, our suppliers or customers, and could decrease demand for our products, create delays and inefficiencies in our supply chain and make it difficult or impossible for us to deliver products to our customers. Further, our headquarters are located in Santa Barbara, California, in a seismically active region that is also prone to forest fires. Any catastrophic event that occurred near our headquarters, or near our manufacturing facilities in China or Malaysia, could impose significant damage to our ability to conduct our business and could require substantial recovery time, which could have an adverse effect on our business, operating results and financial condition.

We may need additional capital, and we cannot be certain that additional financing will be available.

Our operations have been financed primarily through cash flow from operating activities, borrowings under our J.P. Morgan Chase Bank, N.A. Secured Term Loan (the "Term Loan"), which was repaid in the second quarter of fiscal 2021, and the Secured Credit Facility with J.P. Morgan Chase Bank, N.A. (the "Credit Facility") and net proceeds from the sale of our equity securities. In October 2021, subsequent to fiscal 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, which allows us to borrow up to $100 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 may 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.
26

Table of contents

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. We previously reported and remediated material weaknesses in internal control over financial reporting. Completion of remediation does not provide assurance that our remediation or other controls will continue to operate properly. 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.

(1)In November 2020, the Board of Directors authorized a common stock repurchase program of up to $50.0 million. As of October 2, 2021, we had fully utilized the amount available under this common stock repurchase program. Previously, in September 2019 the Board of Directors authorized a common stock repurchase program of up to $50.0 million; as of October 3, 2020, we had fully utilized the amount available under this program. Over the past two fiscal years, we have completed $100.0 million in share repurchases, for 5,181,789 shares, at an average price of $19.30 per share. See Note 8. Stockholder' Equity of the notes to our consolidated financial statements included elsewhere in this Annual Report on Form 10-K for further information. We also withhold shares of common stock in connection with the vesting of restricted stock unit awards issued to such employees to satisfy applicable tax withholding requirements. Although these withheld shares are not issued or considered common stock repurchases under our stock repurchase program and therefore are not included in the preceding table, they are treated as common stock repurchases in our consolidated financial statements as they reduce the number of shares that would have been issued upon vesting.

Overview

Sonos is one of the world's leading sound experience brands. As the inventor of multi-room wireless audio products, Sonos' innovation helps the world listen better by giving people access to the content they love and allowing them to control it however they choose. Known for delivering an unparalleled sound experience, thoughtful design aesthetic, simplicity of use and an open platform, Sonos makes a breadth of audio content available to anyone.

Our sound system provides an immersive listening experience created by our thoughtfully designed speakers and components, our proprietary software platform and the ability to wirelessly stream the content our customers love from the services they prefer. We manage the complexity of delivering a seamless customer experience in a multi-user and open-platform environment. The Sonos sound system is easy to set up, use and expand to bring audio to any room in the home. Through our software platform, we frequently enhance features and services on our products, improving functionality and customer experience.

Our innovative products, seamless customer experience and expanding global footprint have driven 16 consecutive years of sustained revenue growth since our first product launch. We generate revenue from the sale of our Sonos speaker products, including wireless speakers and home theater speakers, from our Sonos system products, which is largely comprised of our component products, and from partner products and other revenue, including partnerships with IKEA and Sonance, Sonos and third-party accessories, licensing, and advertising revenue.

We have developed a robust product and software roadmap that we believe will help us capture the expanding addressable market for our products. We believe executing on our roadmap will position us to acquire new customers, offer a continuously improving experience to our existing customers, and grow follow-on purchases.

COVID-19 Update

In December 2019, the novel coronavirus (COVID-19) was reported in China and subsequently was declared a global pandemic in March 2020 by the World Health Organization. The impact of the pandemic has led to significant challenges to our global economy. Starting in March 2020, we implemented global travel restrictions and work-from-home policies for employees who have the ability to work remotely and we continued to operate with these policies through fiscal 2021. As of the date of this report, these policies have not materially adversely affected our operations, financial reporting or internal controls.

For part of the pandemic, against a backdrop of generally increasing demand, we experienced weakened retail demand due to store closures, modifications of the retail experience, and inventory re-balancing by retail partners. More recently, as retail stores have re-opened and restrictions have eased in more end-markets, we have seen a corresponding return of retail demand. COVID-19 has also affected our supply chain, consistent with its effect across many industries, including causing shipping and logistics challenges, and placing significant limits on component supplies. Especially when combined with the increased demand for our products, these supply chain impacts have resulted in delayed product availability. During our fourth quarter of fiscal 2021, we experienced increased component costs and increased shipping and logistics costs related to
31

these broader industry-wide supply chain challenges. The pandemic has also delayed our efforts to fully diversify our supply chain into Malaysia until fiscal 2022. We expect these impacts, including potential delayed product availability, to continue for as long as the global supply chain is experiencing these challenges. We continue to invest in supply chain initiatives to meet increasing customer demand and address industry-wide capacity challenges. We continue to maintain our liquidity and believe our existing cash and cash equivalent balances, cash flow from operations, and committed credit lines are sufficient to meet our long-term working capital and capital expenditure needs.

While the situation caused by COVID-19 is unprecedented and dynamic, we have considered its impact when developing our estimates and assumptions. Actual results and outcomes may differ from our estimates and assumptions. For additional information of risks related to COVID-19, refer to Part I, Item 1A. Risk factors.

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 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 is net income (loss). In the fiscal years ended October 2, 2021, October 3, 2020, and September 28, 2019, we had a net income of $158.6 million, a net loss of $20.1 million, and $4.8 million, respectively.

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 module revenue from our IKEA partnership, architectural speakers from our Sonance partnership, accessories such as speaker stands and wall mounts, professional services, licensing, and advertising revenue.
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 partnerships with IKEA and Sonance from 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, 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.

Factors Affecting Performance

New Product Introductions. Since 2005, we have released a number of products in multiple audio categories. We intend to introduce new products that appeal to a broad set of consumers, as well as bring our differentiated listening platform and experience to all the places and spaces where our customers listen to the breadth of audio content available, including inside and outside their homes.

Seasonality. Historically, we have typically experienced the highest levels of revenue in the first fiscal quarter of the year coinciding with the holiday shopping season and our promotional activities. Our promotional discounting activity is typically higher in the first fiscal quarter as well, which negatively impacts gross margin during this period. However, our higher sales volume in the holiday shopping season has historically resulted in a higher operating margin in the first fiscal quarter due to positive operating leverage.

Ability to Sell Additional Products to Existing Customers. As our customers add Sonos to their homes and listen to more audio content, they typically increase the number of our products in their homes. In fiscal 2021, follow-on purchases represented approximately 46% of new product registrations. As we execute on our product roadmap to address evolving consumer preferences, we believe we can expand the number of products in our customers’ homes. Our ability to sell additional products to existing customers is a key part of our business model, as follow-on purchases indicate high customer engagement and satisfaction, decrease the likelihood of competitive substitution and result in higher customer lifetime value. We will continue to innovate and invest in product development in order to enhance customer experience and drive sales of additional products to existing customers.

Expansion of Partner Ecosystem. Expanding and maintaining strong relationships with our partners will remain important to our success. Our ability to develop, manufacture and sell voice-enabled speakers that deliver differentiated consumer experiences will be a critical driver of our future performance, particularly as we compete in a larger market with an expanding number of competitors. We currently compete with, and will continue to compete with, companies that have greater resources than we do, many of which have already brought voice-enabled speakers to market. To date, our agreements with these partners have all been on a royalty-free basis. We believe our partner ecosystem improves customer experience, attracting more customers to Sonos, which in turn attracts more partners to the platform further enhancing customer experience. We believe partners choose to be part of the Sonos platform because it provides access to a large, engaged customer base on a global scale. We look to partner with a wide variety of streaming music services, voice assistants, connected home integrators, content creators and podcast providers. We are also partnering with certain companies in the development of our own voice-enabled products. Our competitiveness in the voice-enabled speaker market will depend on successful investment in research and development, market acceptance of our products and our ability to maintain and benefit from these technology partnerships.

As competition increases, we believe our ability to give users the freedom to choose across the broadest set of streaming services and voice control partners will be a key differentiating factor.

Channel Strategy. We are focused on reaching and converting prospective customers through third-party retail stores, e-commerce retailers, custom installers of home audio systems, and our website sonos.com. We are investing in our e-commerce capabilities and in-app experience to drive direct sales. Sales through our direct-to-consumer channel, primarily through sonos.com, increased 46.5% and represented 24.2% of our revenue in fiscal 2021. We believe the growth of our own e-commerce channel will continue to be important to supporting our overall growth and profitability as consumers continue the shift from physical to online sales channels. Our physical retail distribution relies on third-party retailers and our ability to maintain our diversified manufacturing footprint and base of component suppliers. While we seek to increase sales through our direct-to-consumer sales channel, we expect that our partnerships with third-party retailers and custom installers will continue to be an important part of our ecosystem. We will continue to seek retail partners that can deliver differentiated in-

store experiences to support customer demand for product demonstrations. Additionally, we intend to expand and strengthen our partnerships with custom installers who are valuable to our customer base and contribute to our new household growth.

International Expansion. Our products are sold in over 50 countries and in fiscal 2021, 48.1% of our revenue was generated outside the United States. Our international growth will depend on our ability to generate sales from the global population of consumers, develop international distribution channels and diversify our partner ecosystem to appeal to a more global audience. We are committed to strengthening our brand in global markets and our future success will depend in part on our growth in international markets.

Investing in Product and Software Development. Our investments in product and software development consist primarily of expenses in personnel who support our research and development efforts and capital expenditures for new tooling and production line equipment to manufacture and test our products. We believe that our financial performance will significantly depend on the effectiveness of our investments to design and introduce innovative new products and services and enhance existing products and software. If we fail to innovate and expand our product and software offerings or fail to maintain high standards of quality in our products, our brand, market position and revenue will be adversely affected. Further, if our development efforts are not successful, we will not recover the investments made.

Investing in Sales and Marketing. We intend to invest resources in our marketing and brand development efforts. Our marketing investments are focused on increasing brand awareness through advertising, public relations and brand promotion activities. While we maintain a base level of investment throughout the year, significant increases in spending are highly correlated with the holiday shopping season, new product launches and software introductions. We also invest in capital expenditures on product displays to support our retail channel partners. Sales and marketing investments are typically incurred in advance of any revenue benefits from these activities.
Components of Results of Operations

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 module revenue from our IKEA partnership, architectural speakers from our Sonance partnership, and accessories such as speaker stands and wall mounts, as well as professional services, licensing, advertising, and subscription revenue. We attribute revenue from our IKEA partnership to our Asia Pacific ("APAC") region, as our regional revenue is defined by the shipment location. Our revenue is recognized net of allowances for returns, discounts, sales incentives, and any taxes collected from customers. We also defer a portion of our revenue that is allocated to unspecified software upgrades and cloud-based services, as well as for newly launched products sold to resellers not recognized until the date of general availability is reached. Our revenue is subject to fluctuation based on the foreign currency in which our products are sold, principally for sales denominated in the euro and the British pound. The introduction of new products may result in an increase in revenue but may also impact revenue generated from existing products as consumers shift purchases to new products.
For a description of our revenue recognition policies, see the section titled "Critical accounting policies and estimates."

Cost of Revenue
Cost of revenue consists of product costs, including costs of our contract manufacturers for production, component product costs, shipping and handling costs, tariffs, duty costs, warranty replacement costs, packaging, fulfillment costs, manufacturing and tooling equipment depreciation, warehousing costs, hosting costs, and excess and obsolete inventory write-downs. In addition, we allocate certain costs related to management and facilities, personnel-related expenses, and other expenses associated with supply chain logistics. Personnel-related expenses consist of salaries, bonuses, benefits, and stock-based compensation expenses.

Gross Profit and Gross Margin
Our gross margin has fluctuated and may, in the future, fluctuate from period to period based on a number of factors, including the mix of products we sell, the channel mix through which we sell our products, fluctuations of the impacts of our product and material cost saving initiatives, the foreign currency in which our products are sold, and tariffs and duty costs implemented by governmental authorities.

Table of contents

Operating Expenses
Operating expenses consist of research and development, sales and marketing, and general and administrative expenses.

Research and development. Research and development expenses consist primarily of personnel-related expenses, consulting and contractor 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.

Sales and marketing. Sales and marketing expenses consist primarily of advertising and marketing activity for our products and personnel-related expenses, as well as trade show and event costs, sponsorship costs, consulting and contractor expenses, travel costs, product display expenses and related depreciation, customer experience and technology support tool expenses, revenue related sales fees from our direct-to-consumer business, and overhead costs.

General and administrative. General and administrative expenses consist of personnel-related expenses for our finance, legal, human resources and administrative personnel, as well as the costs of professional services, information technology, litigation, patents, related overhead, and other administrative expenses.

Other Income (Expense), Net
Interest income. Interest income consists primarily of interest income earned on our cash and cash equivalents balances.

Interest expense. Interest expense consists primarily of interest expense associated with our debt financing arrangements and amortization of debt issuance costs.

Other income (expense), net. 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.

Provision for (Benefit From) Income Taxes
We are subject to income taxes in the United States and foreign jurisdictions in which we operate. Foreign jurisdictions have statutory tax rates different from those in the United States. Accordingly, our effective tax rate will vary depending on jurisdictional mix of earnings, and changes in tax laws. In addition, certain U.S. tax regulations subject the earnings of our non-U.S. subsidiaries to current taxation in the United States. Our effective tax rate will be impacted by our ability to claim deductions and foreign tax credits to offset the taxation of foreign earnings in the United States.
Deferred income taxes reflect the net tax effects of temporary differences between the carrying amounts of assets and liabilities for financial reporting purposes and the amounts used for income tax purposes. A valuation allowance is provided to reduce our deferred tax assets to amounts that are more-likely-than-not to be realized. We have assessed, on a jurisdictional basis, the available means of recovering deferred tax assets, including the ability to carry back net operating losses, the existence of taxable temporary differences, the availability of tax planning strategies and available sources of future taxable income. We have concluded that future taxable income can be considered a source of income to realize a benefit for deferred tax assets in certain foreign jurisdictions. In addition, we have concluded that a valuation allowance on deferred tax assets in the U.S. and certain foreign jurisdictions continues to be appropriate considering cumulative pre-tax losses in recent years and uncertainty with respect to future taxable income.
During the year ended October 2, 2021, we determined that the net deferred tax asset of our Netherlands subsidiary was more-likely-than-not realizable and released a valuation allowance of $7.8 million resulting in an income tax benefit. We determined that the positive evidence, principally our Netherlands subsidiary being in a cumulative taxable income position with forecasts of future taxable income, outweighed the negative evidence, resulting in the valuation allowance release. It is possible that within the next 12 months there may be sufficient positive evidence to release a portion or all of the remaining valuation allowance. Release of the remaining valuation allowance would result in a benefit to income tax expense for the period the release is recorded, which could have a material impact on net earnings. The timing and amount of the potential valuation allowance release are subject to significant management judgment, as well as prospective earnings in the United States and certain other foreign entities and jurisdictions.

Non-GAAP Financial Measures

To supplement our consolidated financial statements presented in accordance with U.S. GAAP, we monitor and consider adjusted EBITDA and adjusted EBITDA margin, 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, stock-based compensation expense, interest income, interest expense, other income (expense), income taxes and other items that we do not consider representative of underlying operating performance. We define adjusted EBITDA margin as adjusted EBITDA divided by revenue.

37

Table of contents
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 operating 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 non-recurring expenses and other 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.

Total revenue increased $390.4 million, or 29.4%, for fiscal 2021 compared to fiscal 2020. The 53rd week in fiscal 2020 added approximately $25.0 million in fiscal 2020 revenue. Excluding the 53rd week in fiscal 2020, revenue increased approximately 31.9% for fiscal 2021 compared to fiscal 2020. The increase was driven by strong overall demand across all our product categories and the success of new product launches, partially offset by the impact of constrained product availability.

Table of contents
Sonos speakers revenue represented 80.3% of total revenue for fiscal 2021 and increased by 33.2% for fiscal 2021 compared to fiscal 2020 led by the launch of Roam and the continued success of Arc and Sub. Sonos system products revenue represented 15.4% of total revenue for fiscal 2021 and increased 21.2% for fiscal 2021 compared to fiscal 2020. Partner products and other revenue represented 4.2% of total revenue for fiscal 2021 and remained flat for fiscal 2021 compared to fiscal 2020. This category was more significantly impacted by reduced orders as IKEA slowed ordering modules given impacts of COVID-19 and as a result of cyclical product launches.

Volume growth of products sold for fiscal 2021 compared to fiscal 2020 was driven by growth in Sonos speakers and Sonos system products. The rate of increase of volume of products sold and revenue differed for fiscal 2021 compared to fiscal 2020 primarily due to product and channel mix on revenue. This volume growth was partially offset by volume declines by IKEA that slowed ordering modules due to impacts of COVID-19 and as a result of the cyclical product launches.

Revenue for fiscal 2021 compared to fiscal 2020 increased 29.8% in the Americas, increased 31.3% in Europe, Middle East and Africa ("EMEA"), and increased 17.8% in APAC.

In constant currency U.S. dollars, total revenue increased by 25.7% for fiscal 2021 compared to fiscal 2020. We calculate constant currency growth percentages by translating our prior period financial results using the current period average currency exchange rates and comparing these amounts to our current period reported results.

Cost of revenue increased $152.4 million, or 20.2%, from $754.4 million for fiscal 2020 to $906.8 million for fiscal 2021. The increase in cost of revenue was driven by the increase in products sold, as well as expedited air freight shipping, product mix, and an overall increase in shipping and logistics costs incurred related to industry-wide supply chain challenges. This increase was partially offset by a reduction in tariff expenses during the year, recognition of $18.3 million in refunds from tariffs paid in prior periods, product and material cost savings realized in the first quarter of fiscal 2021, and fixed cost leverage on higher sales volume.

Gross margin increased 410 basis points for fiscal 2021 compared to fiscal 2020. The increase was driven by the reduction in tariff costs as we continue to diversify into Malaysia as well as a reduction in tariff rate in the first half of the year compared to the prior year. We also recognized $18.3 million in refunds from tariffs paid in prior periods. Excluding the effects of tariffs in both periods, gross margin would have been 46.9%, an increase of 130 basis points, for fiscal 2021 compared to fiscal 2020. Favorability was mainly driven by lower promotional discounts in the current year compared with the discounts offered in the prior year, which included the "At Home With Sonos" campaign, as well as product and material cost reductions realized in the first quarter of fiscal 2021, fixed cost leverage on higher sales volumes realized in the second and third quarters of fiscal 2021, and a shift in product mix into higher margin products. The increase was partially offset by increased component costs and increased shipping and logistics costs, related to broader industry-wide supply chain challenges. We calculate gross margin excluding the effects of tariffs by removing the net impact of tariffs imposed on goods imported from China to the United States from gross profit divided by total revenue.

The increase was primarily due to higher personnel-related expenses of $12.4 million due to increased headcount and higher bonus, stock-based compensation and related payroll taxes as well as an increase of $5.0 million in product development costs and professional fees. These increases were partially offset by the costs of diversifying our manufacturing into Malaysia in the prior year, and ongoing cost savings associated with the 2020 restructuring plan and a reduction of costs related to global travel restrictions and work-from-home policies due to COVID-19.

This increase was primarily due to higher marketing expenses related to support new product launches of $35.8 million, higher fees resulting from increased sales in our direct-to-consumer channel of $5.8 million, and higher personnel-related expenses due to higher bonus and related payroll taxes of $2.0 million. This was partially offset by cost savings associated with the 2020 restructuring plan of $8.7 million and a reduction of costs related to global travel restrictions and work-from-home policies due to COVID-19.

closures, and other costs related to the 2020 restructuring plan, general and administrative expenses for fiscal 2021 increased compared to fiscal 2020 by 27.8%. This increase was primarily due to $15.7 million incremental legal fees paid in connection with our IP litigation, higher personnel-related expenses of $13.7 million due to increased headcount, higher bonus, stock-based compensation and related payroll tax expenses, as well as $8.7 million in professional fees primarily related to our investments in information technology.

Liquidity and Capital Resources

Our operations are financed primarily through cash flows from operating activities and net proceeds from the sale of our equity securities. As of October 2, 2021, our principal sources of liquidity consisted of cash flows from operating activities,
42

Table of contents
cash and cash equivalents of $640.1 million, including $78.4 million held by our foreign subsidiaries, 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 October 2, 2021, 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.

In response to the impacts of COVID-19, we implemented a number of initiatives to maintain our liquidity and rationalize our operating expenses, and initiated the 2020 restructuring plan during the third quarter of fiscal 2020. 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. In October 2021, subsequent to fiscal 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, which allows us to borrow up to $100 million, with a maturity date of October 2026. (For more information, see Note 15. Subsequent Event of the notes to our consolidated financial statements included elsewhere in this Annual Report on Form 10-K.) 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 provide for operating and financing covenants that would restrict our operations.


Debt Obligations
Prior to repayment, our debt obligation consisted of the Credit Facility. In January 2021, we repaid all of our outstanding principal balance of $24.9 million under the Term Loan which had an original maturity date of October 28, 2021. As of October 2, 2021, we did not have any remaining short- or long-term debt obligations, and as of October 3, 2020, our short- and long-term debt obligations were as follows:

The Credit Facility allowed us to borrow up to $80.0 million restricted to the value of the borrowing base which was based on the value of our inventory and accounts receivable and was subject to quarterly redetermination. The Credit Facility had an original maturity date of October 28, 2021, and could be drawn as Commercial Bank Floating Rate Loans (at the higher of prime rate or adjusted LIBOR plus 2.50%) or Eurocurrency Loans (at LIBOR plus an applicable margin). As of both October 2, 2021, and October 3, 2020, we did not have any outstanding borrowings and had $2.9 million and $0.5 million, respectively, in undrawn letters of credit that reduced the availability under the Credit Facility.

Debt obligations under the Credit Facility required that we maintain a consolidated fixed charge ratio of at least 1.0, restrict distribution of dividends unless certain conditions are met, such as having a fixed charge ratio of at least 1.15, and

required financial statement reporting and delivery of borrowing base certificates. As of October 2, 2021, and October 3, 2020, we were in compliance with all financial covenants. The Credit Facility was collateralized by our eligible inventory and accounts receivable as well as our intellectual property including patents and trademarks. For more information, see Note 15.

Cash Flows from Operating Activities

Net cash provided by operating activities of $253.2 million for fiscal 2021 consisted of net income of $158.6 million, non-cash adjustments of $92.1 million and a net increase in cash related to changes in operating assets and liabilities of $2.6 million. Non-cash adjustments primarily consisted of stock-based compensation expense of $62.1 million, depreciation and amortization of $33.9 million, and impairment and abandonment charges of $3.6 million. The net increase in net operating assets and liabilities was primarily due to an increase in accrued compensation of $33.4 million primarily due to an increase in bonuses, an increase in deferred revenue of $27.6 million, and an increase in accounts payable and accrued expenses of $26.2 million. The increase in net operating assets and liabilities was partially offset by an increase in accounts receivable of $45.7 million driven by revenue growth, an increase in other assets of $30.0 million primarily due to capitalized costs for activities to replace our legacy enterprise resource management system, as well as deferred costs for newly launched products sold not recognized until reaching the date of general availability, an increase in inventory of $7.9 million as well as a decrease in other liabilities $1.1 million.

Cash Flows from Investing Activities

Cash used in investing activities for fiscal 2021 of $45.5 million was primarily due to payments for property, equipment and other assets. Payments for property, equipment, and intangible assets were primarily comprised of manufacturing-related tooling and test equipment to support the launch of new products as well as other assets.
Cash Flows from Financing Activities

Cash provided by financing activities for fiscal 2021 of $25.0 million was primarily by proceeds from the exercise of stock options of $147.8 million, partially offset by $50.0 million for payments for repurchases of common stock, $47.8 million for payments for repurchases of common stock related to shares withheld for taxes associated with vesting of RSUs, as well as repayments for borrowings of $25.0 million.

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 Recognition

Revenue is recognized upon transfer of control of promised products or services to customers in an amount that reflects the consideration we expect to receive in exchange for those products or services. We generally enter into contracts that include a combination of products and services. Revenue is allocated to distinct performance obligations and is recognized net of allowances for returns, discounts, sales incentives and any taxes collected from customers, which are subsequently remitted to governmental authorities. Shipping and handling costs associated with outbound freight after control over a product has transferred to a customer are accounted for as a fulfillment cost and are included in cost of revenue. We do not have material assets related to incremental costs to obtain or fulfill customer contracts.

Nature of Products and Services

Our product revenue primarily includes sales of Sonos speakers and Sonos system products, which 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. We also generate a small portion of revenue from partner products and other revenue sources, such as module revenue from our IKEA partnership, architectural speakers from our Sonance partnership, and accessories such as speaker stands and wall mounts, as well as professional services, licensing and advertising revenue. Module revenue is comprised of hardware and embedded software that is integrated into final products that are manufactured and sold by our partners. Our software primarily consists of firmware embedded in the products and the Sonos app, which is software that can be downloaded to consumer devices at no charge, with or without the purchase of one of our products. Products and related software are accounted for as a single performance obligation and all intended functionality is available to the customer upon purchase. The revenue allocated to the products and related software is the substantial portion of the total sale price. Revenue is recognized at the point in time when control is transferred, which is either upon shipment or upon delivery to the customer, depending on delivery terms.
45

Table of contents

Our 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, which are each distinct performance obligations and are provided to customers at no additional charge. Unspecified software upgrades are provided on a when-and-if-available basis and have historically included updates and enhancements such as bug fixes, feature enhancements and updates to the ability to connect to third-party music or voice assistant platforms. Service revenue is recognized ratably over the estimated service period.

Significant Judgments

Our contracts with customers generally contain promises to transfer products and services as described above. Determining whether products and services are considered distinct performance obligations that should be accounted for separately may require significant judgment.

Determining the standalone selling price ("SSP") for each distinct performance obligation requires judgment. 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.

Determining the revenue recognition period for unspecified software upgrades and cloud services requires judgment. We recognize revenue attributable to these performance obligations ratably over the best estimate of the period that the customer is expected to receive the services. In developing the estimated period of providing future services, 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.

Estimating variable consideration such as sales incentives and product returns requires judgment. We offer sales incentives through various programs, consisting primarily of discounts, cooperative advertising and market development fund programs. We record transactions related to cooperative advertising and market development fund programs with customers as a reduction to revenue unless we receive a distinct benefit in exchange for credits claimed by the customer and can reasonably estimate the fair value of the benefit received, in which case we record them as operating expenses. We recognize a liability, or a reduction to accounts receivable, and reduce revenue for sales incentives based on the estimated amount of sales incentives that will be claimed by customers. Estimates for sales incentives are developed using the most likely amount and are included in the transaction price to the extent that a significant reversal of revenue would not result once the uncertainty is resolved. In developing our estimates, we also consider the susceptibility of the incentive to outside influences, the length of time until the uncertainty is resolved, our experience with similar contracts, and the range of possible outcomes. Reductions in revenue related to discounts are allocated to products and services on a relative basis based on their respective SSP. Judgment is required to determine the timing and amount of recognition of marketing funds, which we estimate based on past practice of providing similar funds.

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. When determining the expected value of returns, we consider future business initiatives and relevant anticipated future events.

Inventories

Inventories consist of finished goods and component parts, which are purchased from contract manufacturers and component suppliers. Inventories are stated at the lower of cost and net realizable value on a first-in, first-out basis. We assess the valuation of inventory balances including an assessment to determine potential excess and/or obsolete inventory. We may be required to write down the value of inventory if estimates of future demand and market conditions indicate estimated excess and/or obsolete inventory.

Product Warranties

Our products are covered by a warranty to be free from defects in material and workmanship for a period of one year, except for products sold in the EU and select other countries where we provide a two-year warranty. At the time of sale, an
46

Table of contents
estimate of future warranty costs is recorded as a component of the cost of revenue. Our estimate of costs to fulfill our warranty obligations is based on historical experience and expectations of future costs to repair or replace.

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 and certain of our foreign deferred tax assets as of October 2, 2021. We intend to continue maintaining a full valuation allowance on our U.S. and certain foreign 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.
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.

Item 7A. Quantitative and Qualitative Disclosures About Market Risk

We are exposed to market risks in the ordinary course of our business. These risks primarily include interest rate and foreign currency risks as follows:

Interest Rate Risk

As of October 2, 2021, we had cash and cash equivalents of $640.1 million, which consisted primarily of cash on hand, money market funds and bank deposits. Such interest-earning instruments carry a degree of interest rate risk due to floating interest rates. However, historical fluctuations of interest income have not been significant.

To date, we have not been exposed, nor do we anticipate being exposed, to material risks due to changes in interest rates. A hypothetical 10% change in interest rates during any of the periods presented would not have had a material impact on our consolidated financial statements.

Foreign Currency Risk

Our inventory purchases are primarily denominated in U.S. dollars. Our international sales are primarily denominated in foreign currencies and any movement in the exchange rate between the U.S. dollar and the currencies in which we conduct sales in foreign countries could have an impact on our revenue, principally for sales denominated in the euro and the British pound. A portion of our operating expenses are incurred outside the United States and are denominated in foreign currencies, which are also subject to foreign currency exchange rate fluctuations. In certain countries where we may invoice customers in the local currency our revenues benefit from a weaker dollar and are adversely affected by a stronger dollar. The opposite impact occurs in countries where we record expenses in local currencies. In those cases, our costs and expenses benefit from a stronger dollar and are adversely affected by a weaker dollar.

We do not currently use foreign exchange contracts or derivatives to hedge any foreign currency exposures. The volatility of exchange rates depends on many factors that we cannot forecast with reliable accuracy. Our continued international expansion increases our exposure to exchange rate fluctuations and, as a result, such fluctuations could have a significant impact on our future results of operations.

We recognized a net gain from foreign currency of $2.4 million in fiscal 2021, a net gain from foreign currency of $6.6 million in fiscal 2020 and a net loss from foreign currency of $8.6 million in fiscal 2019. Based on transactions denominated in currencies other than respective functional currencies as of October 2, 2021, a hypothetical adverse change of 10% would have resulted in an adverse impact on income (loss) before provision for (benefit from) income taxes of approximately $24.3 million for the fiscal year ended 2021.

Report of Independent Registered Public Accounting Firm

To the Board of Directors and Stockholders of Sonos, Inc.

Opinions on the Financial Statements and Internal Control over Financial Reporting

We have audited the accompanying consolidated balance sheets of Sonos, Inc. and its subsidiaries (the “Company”) as of October 2, 2021 and October 3, 2020, and the related consolidated statements of operations and comprehensive income (loss), of stockholders’ equity and of cash flows for each of the three years in the period ended October 2, 2021, including the related notes (collectively referred to as the “consolidated financial statements”). We also have audited the Company's internal control over financial reporting as of October 2, 2021, based on criteria established in Internal Control - Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO).

In our opinion, the consolidated financial statements referred to above present fairly, in all material respects, the financial position of the Company as of October 2, 2021 and October 3, 2020, and the results of its operations and its cash flows for each of the three years in the period ended October 2, 2021 in conformity with accounting principles generally accepted in the United States of America. Also in our opinion, the Company maintained, in all material respects, effective internal control over financial reporting as of October 2, 2021, based on criteria established in Internal Control - Integrated Framework (2013) issued by the COSO.

Basis for Opinions

The Company's management is responsible for these consolidated financial statements, for maintaining effective internal control over financial reporting, and for its assessment of the effectiveness of internal control over financial reporting, included in Management’s Annual Report on Internal Control Over Financial Reporting appearing under Item 9A. Our responsibility is to express opinions on the Company’s consolidated financial statements and on the Company's internal control over financial reporting based on our audits. We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) (PCAOB) and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audits to obtain reasonable assurance about whether the consolidated financial statements are free of material misstatement, whether due to error or fraud, and whether effective internal control over financial reporting was maintained in all material respects.

Our audits of the consolidated financial statements included performing procedures to assess the risks of material misstatement of the consolidated financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the consolidated financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the consolidated financial statements. Our audit of internal control over financial reporting included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, and testing and evaluating the design and operating effectiveness of internal control based on the assessed risk. Our audits also included performing such other procedures as we considered necessary in the circumstances. We believe that our audits provide a reasonable basis for our opinions.

Definition and Limitations of Internal Control over Financial Reporting

A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company’s internal control over financial reporting includes those policies and procedures that (i) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (ii) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (iii) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company’s assets that could have a material effect on the financial statements.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

Critical Audit Matters

The critical audit matter communicated below is a matter arising from the current period audit of the consolidated financial statements that was communicated or required to be communicated to the audit committee and that (i) relates to accounts or disclosures that are material to the consolidated financial statements and (ii) involved our especially challenging, subjective, or complex judgments. The communication of critical audit matters does not alter in any way our opinion on the consolidated financial statements, taken as a whole, and we are not, by communicating the critical audit matter below, providing a separate opinion on the critical audit matter or on the accounts or disclosures to which it relates.

Revenue Recognition - Estimates of Standalone Selling Price and Service Period for Unspecified Software Upgrades and Cloud-Based Services

As described in Notes 2 and 5 to the consolidated financial statements, the Company’s contracts with customers generally contain promises to transfer products and services which are not sold separately. Service revenue includes revenue allocated to (i) unspecified software upgrades and (ii) cloud-based services, which are each distinct performance obligations, based on relative standalone selling price. Management’s estimation of standalone selling price requires judgment. Management has disclosed that there are factors considered including competitive pricing information, where available, analyses of the cost of providing the products or services plus a reasonable gross margin, the nature of the products and services and the expected level of future services. Determining the revenue recognition period for unspecified software upgrades and cloud-based services also requires judgment. Management recognizes revenue attributable to these performance obligations ratably over the estimated service period. In developing the estimated service period over which to recognize service revenue, management considers past history, plans to continue to provide services, including plans to continue to support updates and enhancements to prior versions of the Company’s products, expected technological developments, obsolescence, competition and other factors. Deferred revenue primarily relates to revenue allocated to unspecified software upgrades and cloud-based services and was $70.4 million as of October 2, 2021.

The principal considerations for our determination that performing procedures relating to revenue recognition - specifically estimation of standalone selling prices and service period attributable to unspecified software upgrades and cloud-based services - is a critical audit matter as there was significant judgment by management in estimating the standalone selling price and the service period. This in turn led to significant auditor judgment, subjectivity, and audit effort in performing procedures and evaluating audit evidence relating to (i) estimates of standalone selling price made by management, including estimates of the cost of providing the services plus a reasonable gross margin, and (ii) management’s assumptions in estimating the service period, including management’s plans to continue to support updates and enhancements to prior versions of the Company’s products.

Addressing the matter involved performing procedures and evaluating audit evidence in connection with forming our overall opinion on the consolidated financial statements. These procedures included testing the effectiveness of controls relating to the revenue recognition process, including over the estimation of the standalone selling prices and service period for unspecified software upgrades and cloud-based services. The procedures also included, among others, testing management’s process for estimating the standalone selling price and service period. Procedures performed for the estimates of standalone selling price included (i) evaluating the appropriateness of management’s cost plus gross margin method of estimating standalone selling price (ii) comparing the estimate of standalone selling price to competitive pricing information for comparable services using publicly disclosed information; (iii) evaluating the reasonableness of estimates of the cost of providing the services; and (iv) evaluating the gross margin assumption. Evaluating the estimates of cost of providing the services involved (i) testing the allocation of engineering costs, which is driven by time spent on software upgrades and cloud-based services; and (ii) testing the completeness, accuracy, relevance, and classification of the engineering costs. Evaluating the reasonableness of the gross margin assumption involved comparing management’s gross margin to the gross margin earned for similar services by third party peer companies within the same industry. Procedures were also performed to test management’s process for estimating the service period for these services, including the data on which the estimate is based. This included evaluating the reasonableness of management’s plans to continue to support updates and enhancements to prior versions of the Company’s products through a look-back analysis performed using historical software updates, as well as considering currently active products receiving software updates.

Notes to Consolidated Financial Statements

1. Business Overview

Description of Business
Sonos, Inc. and its wholly owned subsidiaries (collectively, “Sonos,” the “Company,” “we,” “us” or “our”) designs, develops, manufactures and sells audio products and services. The Sonos sound system provides customers with an immersive listening experience created by the design of its speakers and components, a proprietary software platform, and the ability to stream content from a variety of sources over the customer’s wireless network or over Bluetooth.
The Company’s products are sold through third-party physical retailers, including custom installers of home audio systems, select e-commerce retailers, and its website sonos.com. The Company’s products are distributed in over 50 countries through its wholly owned subsidiaries: Sonos Europe B.V. in the Netherlands, Beijing Sonos Technology Co. Ltd. in China, Sonos Japan GK in Japan, and Sonos Australia Pty Ltd. in Australia.
2. Summary of Significant Accounting Policies

Basis of Presentation and Preparation
The consolidated financial statements, which include the accounts of Sonos, Inc. and its wholly owned subsidiaries, have been prepared in conformity with accounting principles generally accepted in the United States ("U.S. GAAP"). All intercompany accounts and transactions have been eliminated in consolidation. Certain prior period amounts have been reclassified to conform to the current period presentation.
The Company operates on a 52-week or 53-week fiscal year ending on the Saturday nearest September 30 each year. The Company’s fiscal year is divided into four quarters of 13 weeks, each beginning on a Sunday and containing two 4-week periods followed by a 5-week period. An additional week is included in the fourth fiscal quarter approximately every five years to realign fiscal quarters with calendar quarters. This last occurred in the Company’s fiscal year ended October 3, 2020, and will reoccur in the fiscal year ending October 3, 2026. As used in the Annual Report on Form 10-K, “fiscal 2021” refers to the 52-week fiscal year ending October 2, 2021, “fiscal 2020” refers to the 53-week fiscal year ended October 3, 2020, and “fiscal 2019” refers to the 52-week fiscal year ended September 28, 2019.

Use of Estimates and Judgments
The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and judgments that affect the amounts reported and disclosed in the consolidated financial statements and accompanying notes. Actual results could differ materially from those estimates. For revenue recognition, examples of estimates and judgments include: determining the nature and timing of satisfaction of performance obligations, determining the standalone selling price ("SSP") of performance obligations and estimating variable consideration such as sales incentives and product returns. Additionally, estimates and judgments are made by management for allowances for credit losses, excess and obsolete inventory, useful lives associated with property and equipment, incremental borrowing rates associated with leases, the recording of and release of valuation allowances with respect to deferred tax assets and uncertain tax positions, impairment of long-lived assets, impairment of goodwill and indefinite-lived intangible assets, warranty, contingencies and valuation and assumptions underlying stock-based compensation and other equity instruments. On an ongoing basis, the Company evaluates its estimates and judgments compared to historical experience and trends that form the basis for making estimates and judgments about the carrying value of assets and liabilities.
In March 2020, the outbreak of the novel coronavirus (COVID-19) was declared a pandemic. While the nature of the situation is dynamic, the Company has considered the impact when developing its estimates and assumptions noted above. Actual results and outcomes may differ from management's estimates and assumptions.

Comprehensive Income (Loss)
Comprehensive income (loss) consists of two components: net income (loss) and other comprehensive income (loss). Other comprehensive income (loss) refers to net gains and losses that are recorded as an element of stockholders’ equity but are excluded from net income (loss). The Company’s other comprehensive income (loss) consists of net unrealized gains and losses on foreign currency translation adjustments from those subsidiaries not using the U.S. dollar as their functional currency.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)

Cash and Cash Equivalents
Cash equivalents consist of short-term, highly liquid financial instruments with insignificant interest rate risk that are readily convertible to cash and have maturities of three months or less from the date of purchase. As of October 2, 2021, and October 3, 2020, cash equivalents consisted of money market funds, which are recorded at fair value.

Restricted Cash

The Company held no restricted cash as of October 2, 2021, and $0.2 million as of October 3, 2020, representing security deposits on real estate leases.

Accounts Receivable

Accounts receivable are recorded at the invoiced amount less allowances for credit losses and sales incentives, do not require collateral and do not bear interest.

The allowance for credit losses is established through a provision for net bad debt expense which is recorded in general and administrative expense in the consolidated statements of operations and comprehensive income (loss). The Company determines the adequacy of the allowance for credit losses by evaluating the collectability of accounts, including consideration of the age of invoices, each customer’s expected ability to pay and collection history, customer-specific information, and current economic conditions that may impact the customer's ability to pay. This estimate is periodically adjusted as a result of the aforementioned process, or when the Company becomes aware of a specific customer’s inability to meet its financial obligations.

Concentration of Credit Risk

Financial instruments that potentially subject the Company to significant concentrations of credit risk consist principally of cash and cash equivalents and accounts receivable. The Company maintains cash and cash equivalents in several high-quality financial institutions. Cash and cash equivalents held at these banks, including those held in foreign branches of global banks, may exceed the amount of insurance provided on such deposits. These deposits may be redeemed upon demand, and management believes that the financial institutions that hold the Company’s cash and cash equivalents are financially sound and, accordingly, minimal credit risk exists with respect to cash. The Company has not experienced any losses in such accounts.

Inventories

Inventories primarily consist of finished goods and, to a lesser extent, component parts, which are purchased from contract manufacturers and component suppliers. Inventories are stated at lower of cost and net realizable value on a first-in, first-out basis. Inventory costs primarily consist of materials, inbound freight, import duties, tariffs, direct labor and manufacturing overhead, logistics, and other handling fees. The Company assesses the valuation of inventory balances including an assessment to determine potential excess and/or obsolete inventory. The Company may be required to write down the value of inventory if estimates of future demand and market conditions indicate excess and/or obsolete inventory. For the periods presented, the Company has not experienced significant write-downs. Ownership of inventory transfers to the Company at the time the goods are shipped from the suppliers. Inventories recorded on the Company's consolidated balance sheets include in transit inventory owned by the Company that have been shipped but have not yet been received at a Company distribution center.

Property and Equipment, Net

Property and equipment are stated at historical cost less accumulated depreciation. Depreciation is calculated using the straight-line method over the estimated useful lives of the related assets as follows:

Computer hardware and software
1-3 years
Furniture and fixtures
2-5 years
Tooling and production line test equipment
2-4 years
Leasehold improvements
2-10 years
Product displays
1-3 years

Costs incurred to improve leased office space are capitalized. Leasehold improvements are amortized on a straight-line basis over the shorter of the term of the lease or the estimated useful life of the improvement. Expenditures for major renewals and improvements that extend the useful lives of property and equipment are capitalized. Maintenance, repair costs and gains or losses associated with disposals are charged to expense as incurred.

Product displays are deployed at retail locations. Because the product displays facilitate marketing of the Company’s products within the retail stores, depreciation for product displays is recorded in sales and marketing expenses in the consolidated statements of operations and comprehensive income (loss).

Cloud Computing Arrangements

The Company incurs costs to implement cloud computing arrangements that are hosted by a third-party vendor. Beginning in fiscal 2020, and continuing through fiscal 2021, the Company began activities to replace its legacy enterprise resource management system in order to accommodate the Company's expanding operations. Implementation costs incurred during the application development stage are capitalized until the software is ready for its intended use. The costs are then amortized on a straight-line basis over the term of the associated hosting arrangement and are recognized as an operating expense within the consolidated statements of operations and comprehensive income (loss). Capitalized costs were $14.3 million and $4.8 million as of October 2, 2021 and October 3, 2020, respectively, and are reported as a component of other assets on the Company's consolidated balance sheets.

Impairment of Goodwill and Indefinite-lived Intangible Assets

Goodwill and indefinite-lived intangible assets are not amortized and are tested for impairment on an annual basis or between annual tests if an event occurs or circumstances change that would more likely than not reduce the fair value of the reporting unit or asset below its carrying value.

In connection with the Company's evaluation of goodwill impairment, the Company performs a qualitative assessment to determine if it is more likely than not that the fair value of a reporting unit is less than its carrying amount. If the qualitative assessment is not conclusive, the Company tests goodwill for impairment, including comparing the fair value of the reporting unit to its carrying value (including attributable goodwill). The Company determines fair value of its reporting unit using an income or market approach incorporating market participant considerations and management’s assumptions on revenue growth rates, operating margins, discount rates and expected capital expenditures. Fair value determinations may include both internal and third-party valuations. The Company performs its annual goodwill impairment assessment during the third quarter of each fiscal year and more frequently if circumstances otherwise dictate.

In connection with the Company’s evaluation of indefinite-lived intangible asset impairment, the Company performs a qualitative assessment to determine if it is more likely than not that the fair value of the asset is less than its carrying amount. If the qualitative assessment is not conclusive, the Company proceeds to test for impairment by comparing the fair value of the asset to the carrying value. Fair value is determined based on estimated discounted future cash flow analyses that include significant management assumptions such as revenue growth rates, weighted-average costs of capital and assumed royalty rates. If the carrying value exceeds fair value, an impairment charge will be recorded to reduce the asset to fair value.


Impairment of Long-Lived Assets

The Company evaluates the recoverability of its long-lived assets, primarily comprised of property and equipment and operating lease right-of-use assets, for impairment whenever events or changes in circumstances indicate that the carrying amounts may not be recoverable. The Company performs impairment testing at the level that represents the lowest level for which identifiable cash flows are largely independent of the cash flows of other assets and liabilities. Recoverability is measured by comparing the carrying amounts to the expected future undiscounted cash flows attributable to the assets. If it is determined that an asset may not be recoverable, an impairment loss equal to the excess of the asset’s carrying value over its fair value is recorded. Fair value is determined based on estimated discounted future cash flows analyses. There were no impairment charges identified on the Company's long-lived assets for fiscal 2021 or fiscal 2019. For fiscal 2020, there were impairment charges incurred related to the 2020 restructuring plan as described within Note 14. Restructuring Plan.

Product Warranties

The Company’s products are covered by warranty to be free from defects in material and workmanship for a period of one year, except in the EU and select other countries where the Company provides a two-year warranty on all its products. At the time of sale, an estimate of future warranty costs is recorded as a component of cost of revenue and a warranty liability is recorded for estimated costs to satisfy the warranty obligation. The Company’s estimate of costs to fulfill its warranty obligations is based on historical experience and expectations of future costs to repair or replace.

Legal Contingencies

If a potential loss from any claim or legal proceeding is considered probable, and the amount can be reasonably estimated, the Company records a liability for an estimated loss. Legal fees are expensed as incurred and included in general and administrative expenses in the consolidated statements of operations and comprehensive income (loss). See Note 12. Commitments and Contingencies for additional information regarding legal contingencies.

Treasury Stock

The Company accounts for treasury stock acquisitions using the cost method. The Company accounts for the retirement of treasury stock by deducting its par value from common stock and reflecting any excess of cost over par value as a deduction from additional paid-in capital on the consolidated balance sheets.
    
Fair Value Accounting

Assets and liabilities recorded at fair value on the consolidated balance sheets are categorized based upon the level of judgment associated with the inputs used to measure their fair value.

Fair value is estimated by applying the following hierarchy, which prioritizes the inputs used to measure fair value into three levels and bases the categorization within the hierarchy upon the lowest level of input that is available and significant to the fair value measurement:
    
Level InputInput Definition
Level 1Quoted prices for identical assets or liabilities in active markets at the measurement date.
Level 2Inputs, other than quoted prices included in Level 1, such as quoted prices for similar assets or liabilities, in active markets or other inputs that are observable or can be corroborated with market data at the measurement date.
Level 3Unobservable inputs that reflect management's best estimate of what market participants would use in pricing the asset or liability at the measurement date.

Foreign Currency

Certain of the Company’s wholly owned subsidiaries have non-U.S. dollar functional currencies. The Company translates assets and liabilities of non-U.S. dollar functional currency subsidiaries into U.S. dollars using exchange rates in effect at the end of each period and stockholders’ equity at historical rates. Revenue and expenses for these subsidiaries are translated using rates that approximate those in effect during the period. Gains and losses from translation are recognized in foreign currency translation included in accumulated other comprehensive loss.

The Company remeasures monetary assets or liabilities denominated in currencies other than the functional currency using exchange rates prevailing on the balance sheet date, and non-monetary assets and liabilities at historical rates. Foreign currency remeasurement and transaction gains and losses are included in other income (expense), net.

Foreign currency remeasurement and transaction gains (losses) are recorded in other income (expense), net as follows:

Revenue Recognition

Revenue is recognized upon transfer of control of promised products or services to customers in an amount that reflects the consideration the Company expects to receive in exchange for those products or services. The Company's contracts generally include a combination of products and services. Revenue is allocated to distinct performance obligations and is recognized net of allowances for returns, discounts, sales incentives and any taxes collected from customers, which are subsequently remitted to governmental authorities. Shipping and handling costs associated with outbound freight after control over a product has transferred to a customer are not considered a separate performance obligation and are accounted for as a fulfillment cost and are included in cost of revenue. As of October 2, 2021, and October 3, 2020, the Company did not have any material assets related to incremental costs to obtain or fulfill customer contracts.

In fiscal 2018, the Company adopted ASC 606 using the full retrospective transition method which resulted in an acceleration of revenue and related costs of revenue and most significantly, a reduction in deferred costs and revenue and deferred revenue at each balance sheet date.

Nature of Products and Services

Product revenue primarily includes sales of Sonos speakers and Sonos system products, which include software that enables the Company’s products to operate over a customer’s wireless network, as well as connect to various third-party services, including music and voice. The Company also generates a small portion of revenue from Partner products and other revenue sources in connection with partnerships, accessories, professional services, licensing, advertising, and subscription revenue. Revenue for module units is related to hardware and embedded software that is integrated into final products that are manufactured and sold by the Company's partners. Software primarily consists of firmware embedded in the products and the Sonos app, which is software that can be downloaded to consumer devices at no charge, with or without the purchase of one of the Company’s products. Products and related software are accounted for as a single performance obligation and all intended functionality is available to the customer upon purchase. The revenue allocated to the products and related software is the substantial portion of the total sale price. Product revenue is recognized at the point in time when control is transferred, which is either upon shipment or upon delivery to the customer, depending on delivery terms.

Service revenue includes revenue allocated to (i) unspecified software upgrades and (ii) cloud-based services that enable products to access third-party music and voice assistant platforms, based on relative standalone selling price, which are each distinct performance obligations and are provided to customers at no additional charge. Unspecified software upgrades are provided on a when-and-if-available basis and have historically included updates and enhancements such as bug fixes, feature enhancements and updates to the ability to connect to third-party music or voice assistant platforms. Service revenue is recognized ratably over the estimated service period.

Significant Judgments

The Company’s contracts with customers generally contain promises to transfer products and services as described above. Determining whether products and services are considered distinct performance obligations that should be accounted for separately requires significant judgment.

Determining the SSP for each distinct performance obligation requires judgment. The Company estimates SSP for items that are not sold separately, which include the products and related software, unspecified software upgrades and cloud-based services, using information that may include competitive pricing information, where available, as well as analyses of the cost of providing the products or services plus a reasonable margin. In developing SSP estimates, the Company also considers the nature of the products and services and the expected level of future services.

Determining the revenue recognition period for unspecified software upgrades and cloud-based services also requires judgment. The Company recognizes revenue attributable to these performance obligations ratably over the best estimate of the period that the customer is expected to receive the services. In developing the estimated period of providing future services, the Company considers past history, plans to continue to provide services, including plans to continue to support updates and enhancements to prior versions of the Company’s products, expected technological developments, obsolescence, competition and other factors. The estimated service period may change in the future in response to competition, technology developments and the Company’s business strategy.

61

Table of contents
SONOS, INC.
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)
The Company offers sales incentives through various programs consisting primarily of discounts, cooperative advertising and market development fund programs. The Company records cooperative advertising and market development fund programs with customers as a reduction to revenue unless it receives a distinct benefit in exchange for credits claimed by the customer and can reasonably estimate the fair value of the benefit received, in which case the Company records it as an expense. The Company recognizes a liability or a reduction to accounts receivable, and reduces revenue based on the estimated amount of sales incentives that will be claimed by customers. Estimates for sales incentives are developed using the most likely amount and are included in the transaction price to the extent that a significant reversal of revenue would not result once the uncertainty is resolved. In developing its estimate, the Company also considers the susceptibility of the incentive to outside influences, the length of time until the uncertainty is resolved and the Company’s experience with similar contracts. Reductions in revenue related to discounts are allocated to products and services on a relative basis based on their respective SSP. Judgment is required to determine the timing and amount of recognition of marketing funds which the Company estimates based on past practice of providing similar funds.

The Company accepts returns from direct customers and from certain resellers. To establish an estimate for returns, the Company uses the expected value method by considering a portfolio of contracts with similar characteristics to calculate the historical returns rate. When determining the expected value of returns, the Company considers future business initiatives and relevant anticipated future events.

Supplier Concentration

The Company relies on third parties for the supply and manufacture of its products, as well as third-party logistics providers. In instances where these parties fail to perform their obligations, the Company may be unable to find alternative suppliers or satisfactorily deliver its products to customers on time, if at all. During fiscal 2021, 2020 and 2019, approximately 59%, 65% and 83%, respectively, of the Company’s finished goods purchased during each year were from one vendor.

Deferred Revenue and Payment Terms

The Company invoices each order upon hardware shipment or delivery and recognizes revenue for each distinct performance obligation when transfer of control has occurred, which in the case of services, may extend over several reporting periods. Amounts invoiced in advance of revenue recognition are recorded as deferred revenue on the consolidated balance sheets. Deferred revenue primarily relates to revenue allocated to unspecified software upgrades and platform services, as well as for newly launched products sold to resellers not recognized until the date of general availability is reached. General availability deferrals are classified as current deferred revenue as the Company starts shipping the product to the reseller within one month prior to the general availability date. The Company classifies deferred revenue as noncurrent if amounts are expected to be recognized as revenue beyond one year from the balance sheet date.

Payment Terms

Payment terms and conditions vary among the Company’s distribution channels although terms generally include a requirement of payment within 30 days of product shipment. Sales directly to customers from the Company’s website are paid at the time of product shipment. Prior to providing payment terms to customers, an evaluation of the customer’s credit risk is performed. Contractual allowances are an offset to accounts receivable.

Research and Development

Research and development expenses consist primarily of personnel-related expenses, consulting and outside professional service costs, tooling and prototype materials and overhead costs. Substantially all of the Company’s research and development expenses are related to developing new products and services and improving existing products and services. To date, software development costs have been expensed as incurred because the period between achieving technological feasibility and the release of the software has been short and development costs qualifying for capitalization have been insignificant.

In-process research and development ("IPRD") assets represent the fair value of incomplete research and development projects obtained as part of a business combination that have not yet reached technological feasibility and are initially not subject to amortization; rather, these assets are subject to impairment considerations of indefinite-lived intangible assets. Upon completion of development, IPRD assets are considered definite-lived intangible assets, transferred to developed
62

Table of contents
SONOS, INC.
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)
technology and are amortized over their useful lives. If a project were to be abandoned, the IPRD would be considered fully impaired and expensed to Research and development.

Advertising Costs

Advertising costs are expensed as incurred and included in sales and marketing expenses. Advertising expenses were $62.3 million, $43.9 million and $48.8 million for fiscal 2021, 2020 and 2019, respectively.

Restructuring and Related Costs

Costs associated with a restructuring plan generally consist of involuntary employee termination benefits, contract termination costs, and other exit-related costs including costs to close facilities. The Company records a liability for involuntary employee termination benefits when management has committed to a plan that establishes the terms of the arrangement and that plan has been communicated to employees. Costs to terminate a contract before the end of the term are recognized on the termination date, and costs that will continue to be incurred in a contract for the remaining term without economic benefit are recognized as of the cease-use date. Restructuring and related costs may also include the write-down of related assets, including operating lease right-of-use assets, when the sale or abandonment of the asset is a direct result of the plan. Other exit-related costs are recognized as incurred. Restructuring and related costs are recognized as an operating expense within the consolidated statements of operations and comprehensive income (loss) and are classified based on the Company's classification policy for each category of operating expense.

Stock-Based Compensation

The Company measures stock-based compensation cost at fair value on the date of grant. Compensation cost for stock options is recognized, on a straight-line basis, as an expense over the period of vesting as the employee performs the related services, net of estimated forfeitures. The Company estimates the fair value of stock option awards using the Black-Scholes option-pricing model. The Company estimates forfeitures based on expected future terminations and will revise rates, as necessary, in subsequent periods if actual forfeitures differ from initial estimates. The fair value of RSUs is based on the Company's closing stock price on the trading day immediately preceding the date of grant.

Retirement Plans

The Company has a defined contribution 401(k) plan (the "401(k) Plan") for the Company’s U.S.-based employees, as well as various defined contribution plans for its international employees. Eligible U.S. employees may make tax-deferred contributions under the 401(k) plan, but are limited to the maximum annual dollar amount allowable under the Internal Revenue Code of 1986, as amended (the "Code"). The Company matches contributions towards the 401(k) Plan and international defined contribution plans. The Company's matching contributions totaled $7.6 million and $6.2 million for fiscal 2021 and 2020, respectively.

Income Taxes

The Company accounts for income taxes under the asset and liability method, which requires the recognition of deferred tax assets and liabilities for the expected future tax consequences of events that have been included in the consolidated financial statements. Under this method, deferred tax assets and liabilities are determined based on the differences between the consolidated financial statements and tax basis of assets and liabilities using enacted tax rates in effect for the year in which the differences are expected to reverse. The effect of a change in tax rates on deferred tax assets and liabilities is recognized in income during the period that includes the enactment date.

The Company records a valuation allowance when necessary to reduce its deferred tax assets to amounts that are more likely than not to be realized. In making such a determination, all available positive and negative evidence is considered, including future reversals of existing taxable temporary differences, projected future taxable income, tax-planning strategies, and results of recent operations. If the Company determines that it would be able to realize its deferred tax assets in the future in excess of their net recorded amount, the Company would make an adjustment to the deferred tax asset valuation allowance, which would result in a benefit to income taxes.

The Company records uncertain tax positions in accordance with a two-step process whereby (i) the Company determines whether it is more likely than not that the tax positions will be sustained on the basis of the technical merits of the
63

Table of contents
SONOS, INC.
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)
position and (ii) for those tax positions that meet the more likely than not recognition threshold, the Company recognizes the largest amount of tax benefit that is more than 50% likely to be realized upon ultimate settlement with the related tax authority.

The Company includes interest and penalties related to unrecognized tax benefits within the provision for income taxes in the consolidated statements of operations and comprehensive income (loss). The Company has not incurred any interest or penalties related to unrecognized tax benefits in any of the periods presented.

The Company’s provision for (benefit from) income taxes, deferred tax assets and liabilities and liabilities for unrecognized tax benefits involves the use of estimates, assumptions and judgments. Although the Company believes its estimates, assumptions and judgments to be reasonable, any changes in tax law or its interpretation of tax laws and the resolutions of potential tax audits could significantly impact the amounts provided for income taxes in the Company’s consolidated financial statements. Actual future operating results and the underlying amount and type of income could differ materially from the Company’s estimates, assumptions and judgments thereby impacting the Company’s financial position and results of operations.

Segment Information

The Company operates as one operating segment as it only reports aggregate financial information on a consolidated basis, accompanied by disaggregated information about revenue by geographic region and product category to its Chief Executive Officer, who is the Company’s chief operating decision maker.

Leases

The substantial majority of the Company’s leases are for its office spaces and facilities, which are accounted for as operating leases. The Company determines whether an arrangement is a lease at inception if there is an identified asset, and if it has the right to control the identified asset for a period of time. Some of the Company’s leases include options to extend the leases for up to 5 years, and some include options to terminate the leases within 1 year. The Company's lease terms are only for periods in which it has enforceable rights and are impacted by options to extend or terminate the lease only when it is reasonably certain that the Company will exercise the option. For leases with terms greater than 12 months, the Company records the related right-of-use asset and lease obligation at the present value of lease payments over the lease terms. Leases with an initial term of 12 months or less are not recorded on the balance sheet. Lease expense is recognized on a straight-line basis over the lease term. Lease agreements will typically exist with lease and non-lease components, which are accounted for separately. The Company's agreements may contain variable lease payments. The Company includes variable lease payments that depend on an index or a rate and exclude those which depend on facts or circumstances occurring after the commencement date, other than the passage of time. As most of the Company’s leases do not contain an implicit interest rate, the Company uses judgment to determine an incremental borrowing rate to use at lease commencement.

Recently Adopted Accounting Pronouncements

In June 2016, the Financial Accounting Standard Board ("FASB") issued ASU No. 2016-13, Financial Instruments - Credit Losses: Measurement of Credit Losses on Financial Instruments, and it subsequently issued amendments to the initial guidance (collectively referred to as "Topic 326"), which provide a new impairment model that requires measurement and recognition of expected credit losses for most financial assets and certain other instruments, including accounts receivable. The Company adopted this standard effective October 4, 2020, using a modified retrospective approach. Under the new standard, the allowance for credit losses is based on the Company's assessment of collectability of accounts, including consideration of the age of invoices, each customer's expected ability to pay and collection history, customer-specific information and current economic conditions that may impact a customer's ability to pay. The adoption of this standard did not have a material impact on the Company's consolidated financial statements.

In November 2018, the FASB issued ASU No. 2018-18, Collaborative Arrangements (Topic 808): Clarifying the Interaction between Topic 808 and Topic 606. This standard resolves the diversity in practice concerning whether certain transactions between collaborative arrangement participants should be accounted for as revenue under Accounting Standards Codification 606, Revenue from Contracts with Customers ("Topic 606"). This standard specifies when a participant is a customer in a collaboration, adds guidance for unit of account to align with Topic 606 and provides presentation guidance for collaborative arrangements. The Company adopted this standard in the first quarter of fiscal 2021. The adoption did not have a material impact on the Company's consolidated financial statements.

Recent Accounting Pronouncements Pending Adoption

In December 2019, the FASB issued ASU No. 2019-12, Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes. This standard simplifies the accounting for income taxes by removing certain exceptions to the general principles in Accounting Standards Codification Topic 740 ("ASC 740") as well as by improving consistent application of the topic by clarifying and amending existing guidance. This standard is effective for the Company in the first quarter of fiscal 2022, with early adoption permitted. The Company will adopt this standard in the first quarter of fiscal 2022 and does not expect it to have a material impact on the Company's consolidated financial statements or disclosures.

6. Leases

The Company entered into various non-cancelable lease agreements for offices and facilities, as well as auto leases. The substantial majority of the Company's leases are for its office spaces and facilities, which are accounted for as operating leases. The Company's main offices are leased in California and Massachusetts, with additional sales, operations, and research and development offices around the world. These facilities operate under leases with initial terms from one to ten years and expire at various dates through 2026. The Company determines whether an arrangement is a lease at inception if there is an identified asset, and it has the right to control the identified asset for a period of time. Some of the Company's leases include options to extend the lease for up to 5 years, and some include options to terminate the lease within 1 year. The Company's lease terms are only for periods in which it has enforceable rights and are impacted by options to extend or terminate the lease only when it is reasonably certain that the Company will exercise the option.

For leases with terms greater than 12 months, the Company records the related right-of-use asset and lease obligation at the present value of lease payments over the lease terms. Leases with an initial term of 12 months or less are not recorded on the balance sheet. Lease expense is recognized on a straight-line basis over the lease term. The Company's leases do not include any residual value guarantees, bargain purchase options or asset retirement obligations.

Lease agreements will typically exist with lease and non-lease components, which are accounted for separately. The Company's agreements may contain variable lease payments. The Company includes variable lease payments that depend on an index or a rate and exclude those which depend on facts or circumstances occurring after the commencement date, other than the passage of time.

Most of the Company's leases do not contain an implicit interest rate. Therefore, the Company uses judgment to estimate an incremental borrowing rate, which is defined as the rate of interest the Company would have to pay to borrow an amount that is equal to the lease obligations, on a collateralized basis, and over a similar term. The Company takes into consideration the terms of the Company's Credit Facility (as defined in Note 7. Debt), lease terms, and current interest rates to determine the incremental borrowing rate at lease commencement date. At October 2, 2021, the Company's weighted-average discount rate was 4.07%, while the weighted-average remaining lease term was 3.8 years. As part of the supplemental cash flow disclosure, the right-of-use assets obtained in exchange for new operating lease liabilities does not reflect the impact of prepaid or deferred rent.

The components of lease expense for the fiscal year ended October 2, 2021, was as follows:

7. Debt

The Company's debt obligation consists of the Secured Credit Facility with J.P. Morgan Chase Bank, N.A. (the “Credit Facility”). In January 2021, the Company repaid all of its outstanding principal balance of $24.9 million under the J.P. Morgan Chase Bank, N.A. Secured Term Loan (the "Term Loan") which had an original maturity date of October 28, 2021. As of October 2, 2021, the Company did not have any remaining short- or long-term debt obligations, and as of October 3, 2020, the Company’s short- and long-term debt obligations were as follows:

(2)Debt issuance costs were recorded as a debt discount and charged to interest expense over the term of the agreement.

The Credit Facility allowed the Company to borrow up to $80.0 million restricted to the value of the borrowing base, which was based on the value of inventory and accounts receivable and was subject to quarterly redetermination. The Credit Facility had an original maturity date of October 28, 2021, and could be drawn as Commercial Bank Floating Rate Loans (at the higher of prime rate or adjusted LIBOR plus 2.50%) or Eurocurrency Loans (at LIBOR plus an applicable margin). As of October 2, 2021, and October 3, 2020, the Company had no outstanding borrowings and $2.9 million and $0.5 million, respectively, in undrawn letters of credit that reduce the availability under the Credit Facility.

Debt obligations under the Credit Facility and the Term Loan required the Company to maintain a consolidated fixed charge ratio of at least 1.0, restrict distribution of dividends unless certain conditions were met, such as having a fixed charge

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)
ratio of at least 1.15, and required financial statement reporting and delivery of borrowing base certificates. As of October 2, 2021, and October 3, 2020, the Company was in compliance with all financial covenants. The Credit Facility and the Term Loan were collateralized by eligible inventory and accounts receivable of the Company, as well as the Company's intellectual property including patents and trademarks. For more information, refer to Note 15. Subsequent Event.

8. Stockholders' Equity

Share Repurchase Program

On November 17, 2020, the Board of Directors authorized a common stock repurchase program of up to $50.0 million. During the fiscal year ended October 2, 2021, the Company repurchased 1,394,006 shares for an aggregate purchase price of $50.0 million at an average price of $35.86 per share under the repurchase program. As of October 2, 2021, the Company fully utilized the amount available under this stock repurchase program.

Treasury stock during the fiscal year ended October 2, 2021, included shares withheld to satisfy employees' tax withholding requirements in connection with vesting of RSUs. Additionally, during the fiscal year ended October 2, 2021, the Company retired 2,602,208 shares of treasury stock. The Company accounts for the retirement of treasury stock by deducting its par value from common stock and reflecting any excess of cost over par value as a deduction from additional paid-in-capital on the consolidated balance sheets.

9. Stock-Based Compensation

2018 Equity Incentive Plan

In July 2018, the Board of Directors (the "Board") adopted the 2018 Equity Incentive Plan (the “2018 Plan”). The 2018 Plan became effective in connection with the Company's initial public offering ("IPO"). The number of shares reserved for issuance under the 2018 Plan increases automatically on January 1 of each year beginning in 2019 and continuing through 2028 by a number of shares of common stock equal to the lesser of (x) 5% of the total outstanding shares of the Company’s common stock and common stock equivalents as of the immediately preceding December 31 (rounded to the nearest whole share) and (y) a number of shares determined by the Company's the Board. As of October 2, 2021, there were 34,376,127 shares reserved for future issuance under the 2018 Plan.

Stock Options

Pursuant to the 2018 Plan, the Company issues stock options to employees and directors. The fair value of the stock options is based on the Company’s closing stock price on the trading day immediately prior to the date of grant. The option price, number of shares and grant date are determined at the discretion of the Board. For so long as the option holder performs services for the Company, the options generally vest over 48 months, on a monthly or quarterly basis, with certain options subject to an initial annual cliff vest, and are exercisable for a period not to exceed ten years from the date of grant.

The Company’s policy for issuing stock upon stock option exercise is to issue new common stock.

Restricted Stock Units

Pursuant to the 2018 Plan, the Company issues RSUs to employees and directors. The fair value of RSUs is based on the Company's closing stock price on the trading day immediately preceding the date of grant.

The Company has assessed, on a jurisdictional basis, the realization of its net deferred tax assets, including the ability to carry back net operating losses, the existence of taxable temporary differences, the availability of tax planning strategies and available sources of future taxable income. The Company has concluded that based on cumulative taxable income and future taxable income that it is able to realize a benefit for net deferred tax assets in certain foreign jurisdictions. In addition, the Company has concluded that a valuation allowance on its net deferred tax assets in the U.S. and certain foreign jurisdictions continues to be appropriate considering cumulative taxable losses in recent years and uncertainty with respect to future taxable income.

During the fiscal year ended October 2, 2021, the Company determined that the net deferred tax asset of its Netherlands subsidiary was more-likely-than-not realizable and released valuation allowance of $7.8 million as an income tax benefit. The Company determined that the positive evidence, principally the Netherlands subsidiary being in a cumulative taxable income position with forecasts of future taxable income, outweighed the negative evidence, resulting in the valuation allowance release. It is possible that within the next 12 months there may be sufficient positive evidence to release a portion or all of the remaining valuation allowance. Release of the remaining valuation allowance would result in a benefit to income tax expense for the period the release is recorded, which could have a material impact on net earnings. The timing and amount of the potential valuation allowance release are subject to significant management judgment, as well as prospective earnings in the United States and certain other foreign entities and jurisdictions.

As of October 2, 2021, the Company had gross U.S. federal net operating loss carryforwards of $101.4 million, of which $70.3 million have an indefinite life and $31.1 million expire beginning in 2035, gross state net operating loss carryforwards of $64.6 million, which expire beginning in 2027, and gross foreign net operating loss carryforwards of $53.3 million with an indefinite life. As of October 2, 2021, the Company also had gross federal and state research and development tax credit carryforwards of $62.0 million and $44.3 million, respectively. The federal research and development tax credits will begin to expire in 2025, and the state research and development tax credits will begin to expire in 2024.

Because of the change of ownership provisions of Sections 382 and 383 of the Internal Revenue Code, and similar state provisions, use of a portion of the Company’s U.S. federal and state net operating loss and research and development tax credit carryforwards may be limited in future periods depending upon changes in ownership. Further, a portion of the carryforwards may expire before being applied to reduce future taxable income and income tax liabilities if sufficient taxable income is not generated in future periods.

In January 2017, the Company entered into a unilateral Advance Pricing Agreement (the "APA") with the Dutch Tax Administration. The APA establishes an intercompany licensing arrangement whereby the operating profit or loss, as determined under U.S. GAAP, of Sonos Europe B.V. and Sonos, Inc. will be allocated between the two companies based on relative contribution to the development of marketing and technology intangibles. The APA has a five-year term that commenced on October 2, 2016, and ended on September 30, 2021. The Company expects operating profit or loss of Sonos Inc. and Sonos Europe B.V. to continue to be allocated in a similar manner for future taxable years.

The Company does not anticipate material changes to its unrecognized benefits within the next 12 months that would result in a material change to the Company’s financial position. The unrecognized tax benefits as of October 2, 2021, would have no impact on the effective tax rate if recognized.

The Company conducts business in a number of jurisdictions and, as such, is required to file income tax returns in multiple jurisdictions globally. U.S. federal income tax returns for the 2017 tax year and earlier are no longer subject to examination by the U.S. Internal Revenue Service (the "IRS"). All U.S. federal and state net operating losses as well as research and development tax credits generated to date, including 2017 and earlier, used in open tax years are subject to adjustment by the IRS and state tax authorities.

The Company recognizes interest and penalties, if any, related to uncertain tax positions in income tax expense. There were no accrued interest or penalties as of October 2, 2021, and October 3, 2020.

As of October 2, 2021, the Company continues to assert that the unremitted earnings in our foreign subsidiaries are permanently reinvested and therefore no deferred taxes or withholding taxes have been provided. If, in the future, the Company decides to repatriate its $5.4 million of undistributed earnings from these subsidiaries in the form of dividends or otherwise, the Company could be subject to withholding taxes payable at that time. Outside basis differences in the Company's foreign subsidiaries including unremitted earnings and any related taxes are not material.

11. Net Income (Loss) Per Share Attributable to Common Stockholders

Basic and diluted net income (loss) per share attributable to common stockholders is presented in conformity with the two-class method required for participating securities. The Company considers its redeemable convertible preferred stock to be participating securities as the holders of redeemable convertible preferred stock were entitled to receive noncumulative dividends in the event that a dividend was paid on common stock. Upon the closing of the IPO, all outstanding shares of the Company’s redeemable convertible preferred stock automatically converted into 32,482,590 shares of common stock on a one-for-one basis.

Basic net income (loss) attributable to common stockholders per share is calculated by dividing net income (loss) attributable to common stockholders by the weighted-average number of shares of common stock outstanding less shares subject to repurchase. Diluted net income (loss) per share attributable to common stockholders adjusts the basic net income (loss) per share attributable to common stockholders and the weighted-average number of shares of common stock outstanding for the potentially dilutive impact of stock awards, using the treasury stock method.

The following table sets forth the computation of the Company’s basic and diluted net income (loss) per share attributable to common stockholders:

Legal Proceedings

From time to time, the Company is involved in legal proceedings in the ordinary course of business, including claims relating to employee relations, business practices and patent infringement. Litigation can be expensive and disruptive to normal business operations. Moreover, the results of complex legal proceedings are difficult to predict, and the Company’s view of these matters may change in the future as the litigation and events related thereto unfold. The Company expenses legal fees as incurred. The Company records a provision for contingent losses when it is both probable that a liability has been incurred and the amount of the loss can be reasonably estimated. An unfavorable outcome to any legal matter, if material, could have an adverse effect on the Company’s operations or its financial position, liquidity or results of operations.

On January 7, 2020, the Company filed a complaint with the U.S. International Trade Commission ("ITC") against Alphabet Inc. ("Alphabet") and Google LLC ("Google") and a lawsuit in the U.S. District Court for the Central District of California against Google. The complaint and lawsuit each allege infringement of certain Sonos patents related to its smart speakers and related technology. On February 6, 2020, the ITC initiated a formal investigation into the Company’s claims. Google and Alphabet filed an initial answer in the ITC action on February 27, 2020, and an amended answer on April 3, 2020, denying infringement and alleging that the asserted patents are invalid. On August 13, 2021, an administrative law judge at the ITC issued an initial determination finding all five of Sonos' asserted patents to be valid and infringed by Google. The judge also ruled that certain proposed redesigns of Google products, one specific redesign per patent, would qualify as non-infringing alternatives to Google's current product designs. The full commission is expected to decide whether and to what extent it will review the initial determination on or before November 19, 2021. On March 4, 2020, the California District Court stayed the district court proceeding pending resolution of the ITC investigation. On March 11, 2020, Google filed an answer in the California District Court, denying infringement and alleging that the asserted patents are invalid.

On September 28, 2020, Google filed for a declaratory judgement of non-infringement in the U.S. District Court for the Northern District of California related to five different Sonos patents. On September 29, 2020, the Company filed a lawsuit against Google in the U.S. District Court for Western District of Texas, alleging infringement of those five Sonos patents and seeking monetary damages and other non-monetary relief. This dispute over venue has now been resolved, with the case proceeding in the Northern District of California, where the judge has bifurcated the case, scheduling early disposition of two representative claims in mid-2022 and trial on all other claims in May 2023. On December 1, 2020, the Company filed a lawsuit against Google Germany GmbH and Google Ireland Ltd. in the regional court of Hamburg, Germany, alleging infringement of a Sonos patent related to control of playback of media by mobile and playback devices and seeking non-monetary relief. Sonos has chosen to withdraw these preliminary injunction actions after having received some preliminary relief.

On June 11, 2020, Google filed a lawsuit in the U.S. District Court for the Northern District of California against the Company, alleging infringement of five Google patents generally related to noise cancellation, digital rights management, media search and wireless relays and seeking monetary damages and other non-monetary relief. On November 2, 2020, the California District Court granted Sonos’ motion to dismiss Google’s allegation of infringement of one of these five Google patents, specifically a patent generally related to media search, finding that the invention at issue is patent ineligible. On June

4, 2021, the California District Court granted a stipulation to dismiss Google's allegation of infringement of another asserted patent involving noise cancellation.

On June 12, 2020, Google filed lawsuits in District Court Munich I against Sonos Europe B.V. and Sonos, Inc., alleging infringement of two Google patents generally related to digital rights management and search notifications, and seeking monetary damages and an injunction preventing sales of any infringing Sonos products. On January 14, 2021, Google amended its infringement complaint related to the search notifications patent to relate to a limited version of the claims, in view of prior art cited by the Company. On March 3, 2021, the District Court Munich stayed a case for infringement of the search notifications patent pending the outcome of a nullity action based on doubt as to the validity of the patent. On June 23, 2021, the Munich court issued a decision dismissing Google's complaint related to the digital rights management patent for lack of infringement of at least two claim features.

On August 21, 2020, Google filed a lawsuit against Sonos, Inc. in Canada, alleging infringement of one Google patent generally related to noise cancellation technology. On August 21, 2020, Google filed a lawsuit against Sonos Europe B.V. and Sonos, Inc. in France, alleging infringement of two Google patents generally related to digital rights management and search notifications, and seeking monetary damages and an injunction preventing sales of any infringing Sonos products. On February 8, 2021, Google withdrew its infringement allegations regarding the search notifications patent in view of prior art brought to the attention of the court by the Company. In August 2020, Google filed a lawsuit against Sonos Europe B.V. and Sonos, Inc. in the Netherlands alleging infringement of a Google patent related to search notifications, and seeking monetary damages and an injunction preventing sales of any infringing Sonos products. In September 2020, Google filed a lawsuit against Sonos Europe B.V. in the Netherlands, alleging infringement of a Google patent related to digital rights management, and seeking monetary damages and enforcement of an injunction preventing sales of any infringing Sonos products, which was transferred to the Midden-Netherlands court on March 22, 2021, following the grant of the Company's challenge to improper jurisdiction. The Netherlands court has now heard argument in both pending Google cases and decisions are expected no earlier than December 2021. A range of loss, if any, associated with these matters is not probable or reasonably estimable as of October 2, 2021.

On March 10, 2017, Implicit, LLC (“Implicit”) filed a patent infringement action in the United States District Court, District of Delaware against the Company. Implicit is asserting that the Company infringed on two patents in this case. The Company denies the allegations. There is no assurance of a favorable outcome and the Company’s business could be adversely affected as a result of a finding that the Company patents-in-suit are invalid and/or unenforceable. A range of loss, if any, associated with this matter is not probable or reasonably estimable as of October 2, 2021.

The Company is involved in certain other litigation matters not listed above but does not consider these matters to be material either individually or in the aggregate at this time. The Company’s view of the matters not listed may change in the future as the litigation and events related thereto unfold.

On May 13, 2020, the Company was granted a temporary exclusion from the August 2019 Section 301 Tariff Action (List 4A) ("Section 301 tariffs") for its component products. On July 23, 2020, the Company was granted a temporary exclusion from Section 301 tariffs for its core speaker products. These exclusions eliminated the tariffs on the Company's component and core speaker products imported from China until August 31, 2020, and entitled the Company to a refund for the tariffs paid since September 2019, the date the Section 301 tariffs were imposed. On August 28, 2020, the United States Trade Representative granted an extension through December 31, 2020, of the exclusion for the Company’s core products, with the Section 301 tariffs for our core products automatically reinstating on January 1, 2021. The exclusion for the Company’s component products was not extended past August 31, 2020, with the Section 301 tariffs for our component products automatically reinstating on September 1, 2020. Tariff refund claims are subject to review and approval by U.S. Customs and Border Protection. As of October 2, 2021, the Company recognized $18.3 million in refunds based upon acceptance of the Company's refund request, recognized as a reduction to cost of revenue, and the outstanding refund receivable was approximately $0.8 million which is recorded in other current assets on the consolidated balance sheets. As of October 2, 2021, the remaining outstanding tariff refund the Company expects to recover was approximately $15.4 million. The Company did not record these potential refunds due to uncertainty of the timing of acceptance of approval and will be recognized as a reduction to cost of revenue if and when acceptance occurs.

Guarantees and Indemnifications

In the normal course of business, the Company enters into agreements that contain a variety of representations and warranties and provide for general indemnification. The Company’s exposure under these agreements is unknown because it involves claims that may be made against the Company in the future, but have not yet been made. To date, the Company has not incurred material costs to defend lawsuits or settle claims related to these indemnification provisions. The Company has also entered into indemnification agreements with its directors and officers that may require the Company to indemnify its directors and officers against liabilities that may arise by reason of their status or service as directors or officers to the fullest extent permitted by the Delaware General Corporation Law. The Company also currently has directors’ and officers’ insurance. No amount has been accrued in the consolidated financial statements with respect to these indemnification guarantees.

14. Restructuring Plan
On June 23, 2020, the Company initiated a restructuring plan as part of its efforts to reduce operating expenses and preserve liquidity due to the uncertainty and challenges stemming from the COVID-19 pandemic (the "2020 restructuring plan"). As part of the 2020 restructuring plan, the Company eliminated approximately 12% of its global headcount and closed its New York retail store and six satellite offices in order to better align resources to provide further operating flexibility and more efficiently position the business for its long-term strategy. Activities under the 2020 restructuring plan were substantially completed in the first quarter of fiscal 2021.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)
Total pre-tax restructuring and related costs under the 2020 restructuring plan were $26.4 million, which was incurred in fiscal 2020. For the assets deemed to be impaired as part of the 2020 restructuring, the Company estimated fair value using an income-approach based on management’s forecast of future cash flows expected to be derived from the property.

The following table summarizes the costs incurred in connection with the 2020 restructuring plan:

Fiscal Year Ended

Property and equipment abandonment charges5,824

Total$26,285 

In the first quarter of fiscal 2021, the Company negotiated the early termination of a facility lease that was part of the 2020 restructuring and recorded a gain of $2.8 million, representing the difference between the related operating lease liability and previously accrued restructuring expenses versus the early termination payment. The gain was recognized as a credit in sales and marketing expenses on the consolidated statements of operations and comprehensive income (loss). The cash paid related to the settlement of the lease liability as part of the early termination is included within "Cash paid for amounts included in the measurement of lease liabilities" within the supplemental disclosure on the consolidated statements of cash flows.
15. Subsequent Events

In October 2021, the Company 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, which replaced its Credit Facility with JPMorgan Chase Bank, N.A. (see Note 7. Debt). The new agreement allows the Company to borrow up to $100 million, with a maturity date of October 2026.

On October 8, 2021 and November 9, 2021, the Company completed two transactions to acquire two privately-held businesses for combined aggregate cash consideration of approximately $27.0 million.

On November 17, the Company announced that its Board of Directors authorized a common stock repurchase program of up to $150.0 million.
