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 throughout the home over the customer’s wireless network.

The Company’s products are distributed in over 50 countries through its wholly owned subsidiaries: Sonos Europe B.V., Beijing Sonos Technology Co., Ltd., Sonos Japan GK and Sonos Australia Pty Ltd., located in the Netherlands, China, Japan and Australia, respectively.

Basis of presentation and preparation

The accompanying condensed consolidated financial statements are unaudited. The condensed consolidated balance sheet as of March 30, 2019 has been derived from the audited financial statements of the Company. The accompanying condensed consolidated financial statements have been prepared in accordance with generally accepted accounting principles in the United States of America (“U.S. GAAP”) for interim financial information, and in management’s opinion, includes all adjustments, consisting of only normal recurring adjustments, necessary for the fair statement of the Company’s financial position, its results of operations and cash flows for the interim periods presented. The results of operations for the  six months ended March 30, 2019  are not necessarily indicative of the results to be expected for the full fiscal year or any other period.

The accompanying condensed consolidated financial statements should be read in conjunction with the consolidated financial statements and notes thereto contained in the Company’s Annual Report on Form 10-K for the fiscal year ended September 29, 2018 (the “Annual Report”), filed with the Securities and Exchange Commission (“SEC”) on November 28, 2018. Certain prior period amounts have been reclassified to conform to the current period presentation.

The Company has a 4-4-5 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 months followed by a 5-week “month.” An additional week is included in the fourth fiscal quarter approximately every five years to realign fiscal quarters with calendar quarters. This last occurred in the fourth quarter of the Company’s fiscal year ended October 3, 2015. The six months ended March 30, 2019 and March 31, 2018 spanned 13 weeks each. As used in this Quarterly Report on Form 10-Q, “fiscal 2019” refers to the fiscal year ending September 28, 2019 and “fiscal 2018” refers to the fiscal year ended September 29, 2018.

Initial public offering

On August 6, 2018, the Company completed its initial public offering (the “IPO”) of its common stock, in which it sold 6,388,888 shares of its common stock, including 833,333 shares of its common stock pursuant to the underwriters’ over-allotment option, and selling stockholders sold 9,583,333 shares of the Company’s common stock, including 1,250,000 shares pursuant to the underwriters’ over-allotment option. The shares were sold at the IPO price of $15.00 per share for net proceeds of $90.6 million , after deducting underwriting discounts and commissions of $5.3 million . Additionally, offering costs incurred by the Company totaled approximately $4.6 million . 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.

Stock split

On July 19, 2018, the Company effected a two -for-one stock split of all outstanding shares of the Company’s capital stock, including its common stock and its redeemable convertible preferred stock. All share and per share information presented in the condensed consolidated financial statements has been retroactively adjusted for all periods presented for the effects of the stock split.

Use of estimates and judgments

The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and judgments that affect the amounts reported and disclosed in the condensed consolidated financial statements and accompanying notes. Actual results could differ materially from those estimates. On an ongoing basis, the Company evaluates its estimates and judgments compared to historical experience and expected trends.

2. Summary of significant accounting policies

There have been no changes in the Company’s significant accounting policies, recently adopted accounting pronouncements, or recent accounting pronouncements pending adoption from those disclosed in the Annual Report, except as noted below.

Recently adopted accounting pronouncements

In June 2018, the Financial Accounting Standards Board (the “FASB”) issued Accounting Standards Update (“ASU”) No. 2018-07, Compensation—Stock Compensation (Topic 718): Improvements to Nonemployee Share-Based Payment Accounting , which aligns the accounting for share-based payment awards issued to nonemployees with the guidance applicable to grants to employees. Under this new standard, equity-classified share-based payment awards issued to nonemployees will be measured on the grant date, instead of the current requirement to remeasure the awards through the performance completion date. Further, compensation cost for awards with performance conditions will be recognized when it is probable the conditions will be achieved, rather than upon the actual achievement. In the second quarter of fiscal 2019, the Company early adopted the standard using the prospective approach. There was no cumulative effect entry needed to adjust the opening retained earnings balance upon adoption. The adoption of this guidance did not have a material impact on the Company's consolidated financial statements.

In August 2016, the FASB issued ASU No. 2016-15, Statement of Cash Flows (Topic 230): Classification of Certain Cash Receipts and Cash Payments , which reduces diversity in practice in how certain transactions are classified in the statement of cash flows. In the first quarter of fiscal 2019, the Company retrospectively adopted this standard to all periods presented in this Quarterly Report on Form 10-Q. The adoption of this guidance did not have a material impact on the Company’s consolidated financial statements.

In October 2016, the FASB issued ASU No. 2016-16, Income Taxes (Topic 740): Intra-Entity Transfers of Assets Other Than Inventory . ASU 2016-16 removes the prohibition in Accounting Standards Codification (“ASC”) Topic 740, Income Taxes , against the immediate recognition of the current and deferred income tax effects of intra-entity transfers of assets other than inventory. ASU 2016-16 is intended to reduce the complexity of U.S. GAAP and diversity in practice related to the tax consequences of certain types of intra-entity asset transfers, particularly those involving intellectual property. In the first quarter of fiscal 2019, the Company adopted this standard on a modified retrospective basis. The adoption of this guidance did not have a material impact on the Company’s consolidated financial statements.

In November 2016, the FASB issued ASU No. 2016-18, Statement of Cash Flows (Topic 230): Restricted Cash , which enhances and clarifies the classification and presentation of restricted cash in the statement of cash flows. In the first quarter of fiscal 2019, the Company adopted this standard retrospectively to all periods presented in this Quarterly Report on Form 10-Q. The Company now includes restricted cash and restricted cash equivalents with cash and cash equivalents when reconciling beginning and ending amounts shown on the statement of cash flows. The adoption of this guidance did not have a material impact on the Company’s consolidated financial statements.

NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)

(unaudited)

In August 2018, the SEC adopted the final rule under SEC Release No. 33-10532, Disclosure Update and Simplification , amending certain disclosure requirements that were redundant, duplicative, overlapping, outdated or superseded. In addition, the amendments expanded the disclosure requirements on the analysis of stockholders’ equity for interim financial statements. Under the amendments, an analysis of changes in each caption of stockholders’ equity presented in the balance sheet must be provided in a note or separate statement. The analysis should present a reconciliation of the beginning balance to the ending balance of each period for which a statement of comprehensive income is required to be filed. This final rule became effective November 5, 2018. In the first quarter of fiscal 2019, the Company adopted this standard for all periods presented in this Quarterly Report on Form 10-Q, presenting the activity of the stockholders’ equity accounts in the accompanying consolidated statements stockholders’ equity (deficit) for the periods presented.

Recent accounting pronouncements pending adoption

In February 2016, the FASB issued ASU 2016-02, Leases (Topic 842) , and other subsequent amendments to amend historical lease accounting in order to increase transparency and comparability among entities. The standard requires lessees to recognize lease assets and lease liabilities on the balance sheet and disclose key information about leasing arrangements. This standard is effective for public entities for fiscal years beginning after December 15, 2018, and interim periods within those years, with early adoption permitted. The Company expects to adopt the new lease standard in the first quarter of fiscal 2020. Upon adoption, the Company will recognize any qualifying right-of-use assets and lease liabilities on its condensed consolidated balance sheets, which will increase the Company’s total assets and total liabilities. The Company is currently evaluating the impact of adoption on its 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 unit of account guidance to align with Topic 606 and provides presentation guidance for collaborative arrangements. This guidance is effective for public entities for fiscal years beginning after December 15, 2019, and for interim periods within those fiscal years, with early adoption permitted. The Company is currently evaluating the timing of the adoption and its impact on the Company’s consolidated financial statements.

In August 2018, the FASB issued ASU No. 2018-15, Intangibles—Goodwill and Other—Internal-Use Software (Subtopic 350- 40): Customer’s Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement That Is a Service Contract . The new guidance aligns the requirements for capitalizing implementation costs incurred in a cloud computing arrangement that is a service contract, with the requirements for capitalizing implementation costs incurred to develop or obtain internal-use software. The standard will be effective for the Company in the first quarter of fiscal 2021, with early adoption permitted. The Company is currently evaluating the timing of adoption and impact on the Company's consolidated financial statements.

3. Fair value measurements

The carrying values of the Company’s financial instruments, including accounts receivable and accounts payable, approximate their fair values due to the short period of time to maturity or repayment. The carrying values of the Company’s long-term debt approximate their fair values as of March 30, 2019 and September 29, 2018 as the debt carries a variable rate or market rates that approximate those currently available to the Company.

Item 2. Management's discussion and analysis of financial condition and results of operations

The following discussion and analysis of our financial condition and results of operations should be read in conjunction with our condensed consolidated financial statements and related notes included in Part I, Item 1 of this Quarterly Report on Form 10-Q and with our audited consolidated financial statements included in our Annual Report.

We have a 4-4-5 fiscal year ending on the Saturday nearest September 30 each year. Our fiscal year is divided into four quarters of 13 weeks, each beginning on a Sunday and containing two 4-week months followed by a 5-week “month.”

Forward-looking statements

This Quarterly Report on Form 10-Q contains forward-looking statements. All statements other than statements of historical facts contained in this Quarterly Report on Form 10-Q, including statements regarding future operations are forward-looking statements. In some cases, forward-looking statements may be identified by words such as “believe,” “may,” “will,” “estimate,” “continue,” “anticipate,” “intend,” “could,” “would,” “expect,” “objective,” “plan,” “potential,” “seek,” “grow,” “target,” “if,” and similar expressions intended to identify forward-looking statements. We have based these forward-looking statements largely on our current expectations and projections about future events and trends that we believe may affect our financial condition, results of operations, business strategy, short-term and long-term business operations and objectives and financial needs. These forward-looking statements are subject to a number of risks, uncertainties and assumptions, including those described in the section titled “Risk Factors” set forth in Part II, Item 1A of this Quarterly Report on Form 10-Q and in our other SEC filings, including our Annual Report. Moreover, we operate in a very competitive and rapidly changing environment. New risks emerge from time to time. It is not possible for our management to predict all risks, nor can we assess the impact of all factors on our business or the extent to which any factor, or combination of factors, may cause actual results to differ materially from those contained in any forward-looking statements we may make. In light of these risks, uncertainties and assumptions, the future events and trends discussed in this Quarterly Report on Form 10-Q may not occur and actual results may differ materially and adversely from those anticipated or implied in the forward-looking statements. You should read this Quarterly Report on Form 10-Q with the understanding that our actual future results, levels of activity, performance and events and circumstances may be materially different from what we expect.

Overview

Sonos was founded with a clear mission—to fill every home with music. This mission led us to invent wireless multi-room home audio. Sonos transforms the way people live and interact by restoring the shared experience of music throughout the home. Our home 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 generate substantially all revenue from the sale of our wireless speakers, home theater speakers and component products, as new customers buy our products and existing customers continue to add products to their Sonos home sound systems. Our wireless speakers include Play:1, Play:3 and Play:5, as well as Sonos One, which includes native voice control. Our home theater products include Playbar, Playbase and Sub, as well as the recently released Sonos Beam, which includes native voice control. Our component products include Connect, Connect:Amp and Sonos Amp, as well as our architectural speakers recently released in connection with our Sonance partnership. We also generate revenue from other sources, such as module revenue from our IKEA partnership, the sale of Sonos and third-party accessories like speaker stands and wall mounts, as well as licensing revenue. We sell our products primarily through over 10,000 third-party physical retailers, 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. We operate offices and development labs worldwide, with a significant presence in the United States, the Netherlands and China.

Key metrics

In addition to the measures presented in our condensed consolidated financial statements, we use the following additional 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 products sold, adjusted EBITDA and adjusted EBITDA margin.

Net income (loss) is the most directly comparable financial measure calculated under U.S. GAAP for adjusted EBITDA. In the three months ended March 30, 2019 and March 31, 2018 , we had net loss of $22.8 million and $32.6 million, respectively. In the six months ended March 30, 2019 and March 31, 2018 , we had net income of $38.8 million and $13.1 million, respectively.

	Three Months Ended								Six Months Ended
	March 30, 2019				March 31, 2018				March 30, 2019				March 31, 2018
(in thousands, except percentages)
Products sold	785				778				3,170				3,071
Adjusted EBITDA	$	(2,757	)		$	(14,845	)		$	84,662			$	50,511
Adjusted EBITDA margin	(1.3		)%		(8.0		)%		12.0		%		7.7		%

Products sold

Products sold represents the number of products that are sold during a period, net of returns. Products sold includes the sale of wireless speakers, home theater speakers and components. Products sold excludes the sale of other products, such as module units from our IKEA partnership and Sonos and third-party accessories. Historically, the sale of other items has not materially contributed to our revenue. 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 and the introduction of new products that may have higher or lower than average selling prices.

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 expense, net, other income (expense), net and provision for (benefit from) income taxes. We define adjusted EBITDA margin as adjusted EBITDA divided by revenue. See “Non-GAAP financial measures” below for information regarding our use of adjusted EBITDA and adjusted EBITDA margin and a reconciliation of net income to adjusted EBITDA.

Non-GAAP financial measures

To supplement our condensed 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.

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, enhance the overall understanding of our past performance and future prospects and allow for greater transparency with respect to key financial metrics 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. Some of these limitations are:

•	these non-GAAP financial measures exclude depreciation and, although these are non-cash expenses, the assets being depreciated may be replaced in the future;

•	these non-GAAP financial measures 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;

•	these non-GAAP financial measures 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;

•	these non-GAAP financial measures do not reflect the effect of foreign currency exchange gains or losses, which is included in other income (expense), net;

•	these non-GAAP financial measures do not reflect income tax payments that reduce cash available to us; and

•	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.

The following table presents a reconciliation of net income (loss) to adjusted EBITDA:

	Three Months Ended								Six Months Ended

Factors affecting performance

New product introductions. To date, new product introductions have had a positive impact on our revenue. New product launches and changes in our product mix can contribute to significant year-over-year revenue variability. When new products are introduced, initial sales of the product to our retail channel partners can lead to revenue that is higher than normal for the period. Additionally, although channels are typically filled before general availability, revenue recognition related to new product introductions is delayed until the date of general availability, which can magnify the impact of a new product launch in quarters where there is a general availability launch.

Table of contents

Seasonality . Historically, we have experienced the highest levels of revenue in the first fiscal quarter of the year, coinciding with the holiday shopping season. Our promotional discounting activity is 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.

Components of results of operations

Revenue

We generate substantially all of our revenue from the sale of wireless speakers, home theater speakers and components. We also generate a small portion of our revenue from other revenue sources, such as module revenue from our IKEA partnership, the sale of Sonos and third-party accessories like speaker stands and wall mounts, as well as professional services and licensing revenue. We attribute our revenue from our IKEA partnership to our other product category and to our APAC region, which is determined by the address we ship the module units to. 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. 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.

Cost of revenue

Cost of revenue consists of product costs, including costs of our contract manufacturers for production, component costs, shipping and handling 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 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 and the foreign currency in which our products are sold. As we increase the pace of our product introductions, we expect our gross margin to decline in the near to intermediate term as new products gain a larger share of our overall product mix. We have historically seen that the gross margin for our newly released products are lowest at launch and have tended to increase over time as we realize cost efficiencies. In addition, our ability to reduce the cost of our products is critical to increasing our gross margin over the long term. In this regard, we believe our ability to achieve these results could potentially be impacted through calendar year 2019 due to an industry-wide supply shortage of certain electrical components, arising from an imbalance of global demand and supply capacity and related increases in the costs of these components.

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. We expect to continue to invest in research and development as we develop new products.

Sales and marketing . Sales and marketing expenses consist primarily of advertising and marketing promotions of our products and personnel-related expenses, as well as trade show and event costs, sponsorship costs, consulting and contractor expenses, travel, product display expenses and related depreciation, customer care costs and overhead costs.

26

---

Table of contents

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 expenses, patent costs, related overhead and other administrative expenses. We expect our general and administrative expenses to increase in absolute dollars due to the growth of our business and related infrastructure as well as legal, accounting, insurance, investor relations and other costs associated with becoming a public company.

Other income (expense), net

Interest income (expense), net. Interest income consists primarily of interest income earned on our cash and cash equivalents balances. 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 the relative proportion of foreign to U.S. income, the utilization of foreign tax credits and changes in tax laws.

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 when it is more likely than not that the deferred tax assets will not be realized. We have established a full valuation allowance to offset our U.S. and certain foreign net deferred tax assets due to the uncertainty of realizing future tax benefits from our net operating loss carryforwards and other deferred tax assets. It is possible that within the next 12 months there may be sufficient evidence to release a significant portion of the valuation allowance. Release of the U.S. valuation allowance would result in the establishment of certain deferred tax assets and a benefit to income tax expense for the period the release is recorded which could have a material impact on net earnings. The exact timing and amount of the valuation allowance release are subject to change based on the level of profitability achieved.

Total revenue	$	210,173			$	186,720			$	23,453			12.6	%
Total products sold	785				778				7				0.9	%

Total revenue increased by $23.5 million, or 12.6% , from $186.7 million for the three months ended March 31, 2018 to $210.2 million for the three months ended March 30, 2019 , primarily due to strong growth in home theater products related to the launch of our newest home theater product, Sonos Beam, which launched in July 2018, and an increase in sales of our Sub product. Revenue growth was also attributed to the launch of Sonos Amp in November 2018. This growth was partially offset by an overall decrease in revenue from our wireless speakers category, primarily driven by decreases in sales in the Play:1, due to volume mix shifting from Play:1 to Sonos One, and Play:3 speakers due to discontinuing Play:3 from our product portfolio in fiscal 2018.The decrease from our wireless speakers category was offset in part by increases in sales of Sonos One speakers.

Products sold increased by 0.9% for the three months ended March 30, 2019 compared to the three months ended March 31, 2018 . The volume growth was primarily driven by sales of Sonos Beam, Sonos One and Sub products. Volume growth was partially offset by a decrease in sales of our wireless speaker products, Play:3 and Play:1 speakers.

Revenue from the Americas increased $ 23.4 million, or 25.1% , from $ 93.0 million for the three months ended March 31, 2018 to $ 116.3 million for the three months ended March 30, 2019 . The increase in Americas revenue was driven by strong growth in home theater products related to the launch of Sonos Beam, the addition of retailers, and growth in component products. Revenue growth in the period was partially offset by decreased revenue in wireless speaker products due to reduced sales of our Play:1 and Play:3 speakers.

Revenue from EMEA decreased $ 4.6 million, or 5.5% , from $ 83.9 million for the three months ended March 31, 2018 to $ 79.3 million for the three months ended March 30, 2019 . The decrease in EMEA revenue was driven by decreases in sales of wireless speaker products, partially offset by increased sales of home theater products and components.

Revenue from APAC increased $ 4.7 million, or 48.3% , from $ 9.8 million for the three months ended March 31, 2018 to $ 14.5 million for the three months ended March 30, 2019 . The increase in APAC revenue was primarily driven by revenue related to our partnership with IKEA.

In constant U.S. dollars, total revenue increased by 17.1% for the three months ended March 30, 2019 compared to the three months ended March 31, 2018 , which excludes the impact of foreign currencies weakening against the U.S. dollar. 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.

We also saw revenue growth in our components products driven by the launch of Sonos Amp in November 2018. This growth was partially offset by an overall decrease in revenue from our wireless speaker category, primarily driven by decreases in sales of our Play:1, Play:3 and Play:5 speakers due to discontinuing Play:3 from our product portfolio in fiscal 2018 and volume mix shifting from Play:1 to Sonos One, offset in part, by increases in sales of Sonos One speakers.

Products sold increased by 0.1 million, or 3.2% , from 3.1 million for the six months ended March 31, 2018 to 3.2 million for the six months ended March 30, 2019 .

The increase in Americas revenue was driven by strong growth in home theater products related to the launch of Sonos Beam, the addition of retailers and growth in component products. Although sales of Sonos One increased year-over-year, revenue growth in the period was partially offset by decreased revenue in wireless speaker products due to reduced sales of our Play:1, Play:3 and Play:5 speakers.

Revenue from EMEA decreased $ 3.8 million, or 1.3% , from $ 299.2 million for the six months ended March 31, 2018 to $ 295.4 million for the six months ended March 30, 2019 . The decrease in EMEA revenue was driven by decreases in wireless speaker products, and was partially offset by increased sales of home theater products related to the launch of Sonos Beam.

Revenue from APAC increased $ 4.3 million, or 13.7% , from $ 31.7 million for the six months ended March 31, 2018 to $ 36.1 million for the six months ended March 30, 2019 . The increase in APAC revenue was primarily driven by sales revenue related to our partnership with IKEA.

In constant U.S. dollars, total revenue increased by 10.3% for the six months ended March 30, 2019 compared to the six months ended March 31, 2018 , which excludes the impact of foreign currencies weakening against the U.S. dollar.

Provision for (benefit from) income taxes changed from a provision of $0.6 million for the three months ended March 31, 2018 to a benefit from income taxes of $ 0.2 million for the three months ended March 30, 2019 .

For the three-months ended March 30, 2019 , we recorded a provision for income taxes of $0.2 million for certain profitable foreign entities and a benefit of $0.4 million for U.S. federal and state income tax for a total benefit of $0.2 million. For the three months ended March 30, 2019 , we calculated our U.S. income tax provision using the discrete method as though the interim year to date period was an annual period. We believe that the application of the estimated annual effective tax rate (“AETR”) method generally required by ASC 740 is impractical for the U.S. tax provision given that normal deviations in the projected pre-tax net income (loss) in the U.S. could result in a disproportionate and unreliable effective tax rate under the AETR method. We recorded a provision for income taxes of $0.6 million for certain profitable foreign entities for the three months ended March 31, 2018 .

Liquidity and capital resources

Our operations are financed primarily through cash flow from operating activities, net proceeds from the sale of our equity securities, including net proceeds of $90.6 million from the closing of our IPO on August 6, 2018, and borrowings under our credit facilities. As of March 30, 2019 , our principal sources of liquidity consisted of cash flow from operating activities, cash and cash equivalents of $295.3 million, including $ 25.0 million held by our foreign subsidiaries, 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 March 30, 2019 , as they are required to fund needs outside 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 in order to repatriate these funds.

We believe our existing cash and cash equivalent balances, cash flow from operations and committed credit lines will be sufficient to meet our working capital and capital expenditure needs for the next 12 months. 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, market acceptance of our products and overall economic conditions. To the extent that current and anticipated future 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 additional dilution to our stockholders. The incurrence of debt financing would result in debt service obligations and the instruments governing such debt could provide for operating and financing covenants that would restrict our operations.

Credit facilities

Our credit facilities are as follows:

	As of
	March 30, 2019							September 29, 2018
	Rate			Balance				Rate			Balance
(dollars in thousands)
Term Loan (1)	5.1	%		$	40,000			4.8	%		$	40,000
Unamortized debt issuance costs (2)				(199		)					(236		)
Total indebtedness				$	39,801						$	39,764
Less short-term portion				(10,000		)					(6,667		)
Long-term debt				$	29,801						$	33,097

(1)	Bears interest at a variable rate equal to an adjusted LIBOR plus 2.25% and is payable quarterly. Due in October 2021, with quarterly principal payments beginning in July 2019.

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

The Credit Facility and the Term Loan require us to 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 require financial statement reporting and delivery of borrowing base certificates. As of March 30, 2019 and September 29, 2018 , we were in compliance with all financial covenants.

Obligations under the Term Loan and the Credit Facility are collateralized by our eligible inventory and accounts receivable as well as our intellectual property including patents and trademarks. As of both March 30, 2019 and September 29, 2018 , we did not have any outstanding borrowings and had $ 4.5 million in undrawn letters of credit that reduce the availability under the Credit Facility. As of both March 30, 2019 and September 29, 2018 , we had $ 39.8 million outstanding on the Term Loan.

Cash used in investing activities for the six months ended March 30, 2019 of $8.1 million was due to payments for property and equipment, which were primarily comprised of marketing-related product displays and manufacturing-related tooling and test equipment to support the launch of new products.

Cash used in investing activities for the six months ended March 31, 2018 of $21.9 million was due to payments for property and equipment, which primarily comprised of marketing-related purchases predominantly for product displays and manufacturing-related tooling and test equipment to support the launch of new products.

Cash flows from financing activities

Cash provided by financing activities for the six months ended March 30, 2019 of $17.8 million primarily consisted of proceeds from exercise of stock options of $18.9 million , partially offset by final payments of offering costs of $0.6 million and payments for purchases of treasury stock of $0.6 million .

Cash provided by financing activities for the six months ended March 31, 2018 of $2.3 million primarily consisted of net proceeds of $30.0 million from revolving credit facilities and proceeds from the exercise of common stock options of $4.4 million. These increases were offset by a net paydown of our revolving credit facilities of $30.0 million, payment of offering costs of $1.3 million, and $0.8 million for payments for purchase of treasury stock.

Commitments and contingencies

At March 30, 2019 , we had $45.4 million in non-cancelable purchase commitments for inventory we expect to purchase in the remainder of fiscal 2019 .

Off-balance sheet arrangements

We have not entered into any off-balance sheet arrangements, except as described above, and do not have any holdings in variable interest entities.

Critical accounting policies and estimates

Our unaudited condensed consolidated financial statements are prepared in accordance with U.S. GAAP. The preparation of these unaudited condensed 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.

Other than items discussed in Note 2 of our condensed consolidated financial statements, there have been no material changes to our critical accounting policies as compared to the critical accounting policies and significant judgments and estimates disclosed in our Annual Report.

Item 3.    Quantitative and qualitative disclosures about market risk

We are exposed to financial market risks, including changes in currency exchange rates and interest rates. For quantitative and qualitative disclosures about market risk, refer to Part II, Item 7A, Quantitative and Qualitative Disclosures About Market Risk, in our Annual Report. Our exposure to market risk has not changed materially, except as follows:

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.

We recognized a loss of $ 0.7 million and a gain of $ 2.8 million from foreign currency gains and losses for the three months ended March 30, 2019 and March 31, 2018 , respectively. We recognized a loss of $ 4.7 million and a gain of $ 3.4 million from foreign currency gains for the six months ended March 30, 2019 and March 31, 2018 , respectively. Based on transactions denominated in currencies other than respective functional currencies as of March 30, 2019 , a hypothetical adverse change of 10% would have resulted in an adverse impact on income before income taxes of approximately $ 1.4 million for the three months ended March 30, 2019 and $ 7.3 million for the six months ended March 30, 2019 .

Item 4.    Controls and procedures

Evaluation of disclosure controls and procedures

Our management, with the participation of our Chief Executive Officer and Chief Financial Officer, has evaluated the effectiveness of our disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934, as amended), as of the end of the period covered by this Quarterly Report on Form 10-Q.

Based on the evaluation of our disclosure controls and procedures as of March 30, 2019 , our Chief Executive Officer and Chief Financial Officer concluded that as a result of the material weaknesses in our internal control over financial reporting that were disclosed in our Annual Report, our disclosure controls and procedures were not effective as of March 30, 2019 .

Notwithstanding the material weaknesses, our management has concluded that the condensed consolidated financial statements included elsewhere in this Quarterly Report on Form 10-Q present fairly, in all material respects, our financial position, results of operations and cash flows in conformity with GAAP.

Management’s plan to remediate the material weaknesses

As previously described in Part II, Item 9A of our Annual Report, we began implementing a remediation plan to address the material weaknesses mentioned above. The initiatives we are implementing to remediate the material weaknesses are subject to continued management review supported by confirmation and testing, as well as audit committee oversight. We will continue to implement measures to remedy our internal control deficiencies through the end of fiscal 2019, which coincides with the first year in which we will be required to provide the management's report on internal control over financial reporting under Section 404 of the Sarbanes-Oxley Act of 2002 (the “Sarbanes-Oxley Act”).

Changes in internal control

Other than the changes intended to remediate the material weaknesses noted above, there were no changes in our internal control over financial reporting during the three months ended March 30, 2019 that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

PART II. OTHER INFORMATION

Item 1. Legal proceedings

From time to time, we may become involved in legal proceedings or be subject to claims arising in the ordinary course of our business. Other than the matters described in Note 7 of the notes to our condensed consolidated financial statements included in Part I, Item 1 of this Quarterly Report on Form 10-Q, we are not presently a party to any legal proceedings that in the opinion of our management, if determined adversely to us, would individually or taken together have a material adverse effect on our business, operating results, financial condition or cash flows. Regardless of the outcome, litigation can have an adverse impact on us because of defense and settlement costs, diversion of management resources, and other factors.

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 Quarterly Report on Form 10-Q, including our condensed 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.

Risks related to our business

We have a recent history of losses and expect to incur increased operating costs in the future, and we may not achieve or sustain profitability.

We have experienced net losses in our recent annual periods. In the fiscal years ended September 29, 2018 , September 30, 2017 and October 1, 2016 , we had net losses of $ 15.6 million, $ 14.2 million and $ 38.2 million, respectively. We had an accumulated deficit of $ 164.8 million as of March 30, 2019 . We expect our operating expenses to increase in the future as we expand our operations and execute on our product roadmap. 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 achieve and maintain profitability in the future. We cannot assure you that our revenue will continue to grow or that it will not decline. In addition, we anticipate that new product introductions will adversely impact our gross margin in the near to intermediate term due to the increasing frequency of these product introductions and their anticipated increased share of our overall product volume. In the past, we have taken cost savings initiatives, including our reorganization effort in the third quarter of fiscal 2018. However, our cost savings initiatives do not assure our profitability. Additional reorganizations may be implemented in the future and cost savings may be offset by future hiring or other costs to pursue strategic objectives. Our revenue may decline, or we may incur significant losses for a number of reasons, including the other risks and uncertainties described in these Risk Factors.

The pace of our revenue growth has been volatile, and we cannot assure you that we will continue to achieve consistent revenue growth.

We have experienced volatile revenue growth and demand for our products since launching our first product in 2005. Our revenue grew 14.6 % in fiscal 2018 over fiscal 2017 , 10.1 % in fiscal 2017 over fiscal 2016 and 6.8 % in

41

Table of contents

fiscal 2016 over fiscal 2015 . Our historical revenue growth rates therefore should not be considered indicative of our future performance. Additionally, because our ability to achieve continued growth will depend on our ability to execute on our product roadmap, we cannot guarantee that our revenue will continue to grow. In order for our revenue growth to continue, and for the volatility of our growth to stabilize, we will need to be successful in determining the market opportunity for new products and developing and delivering products that appeal to consumers and stimulate demand. If we are unable to do so, our revenue may not grow as anticipated or at all, and the trading price of our common stock may decline.

The volatility of our revenue growth could cause our operating expenses to exceed our revenue in some periods. The unpredictable nature of the growth and expansion of our business and product offerings also places a continuous and significant strain on our management, operational and financial resources. In future periods, we could experience a decline in revenue, or revenue could grow more slowly than we expect, which could have a material negative effect on our operating results and our stock price could be harmed.

Our operating results depend on a number of factors and are likely to fluctuate from quarter to quarter, which makes them difficult to predict and which could cause the trading price of our common stock to decline.

Our operating results and other key metrics have fluctuated in the past and may continue to fluctuate from quarter to quarter. We expect that this trend will continue as a result of a number of factors, many of which are outside of our control and may be difficult to predict, including:

•	fluctuations in demand for our products, including seasonal variations;

•	the timing and success of new product introductions, which products initially tend to have a lower gross margin;

•	the timing and success of new product introductions by our competitors;

•	pricing pressure as a result of competition or otherwise;

•	shifts in product, geographic or channel mix;

•	the imposition of tariffs and other trade barriers, and the effects of retaliatory trade measures;

•	delays or disruptions in our supply, manufacturing or distribution chain;

•	fluctuations in costs and availability of raw materials and components, and in other manufacturing costs;

•	fluctuations in levels of channel inventory;

•	amount and timing of sales and marketing and other operating expenses related to maintenance and expansion of our business;

•	negative publicity about our products;

•	adverse litigation judgments, settlements or other litigation-related costs, especially from litigation involving alleged patent infringement or defense of our patents;

•	fluctuations in foreign exchange rates;

•	changes in tax rates or adverse changes in tax laws that expose us to additional income tax liabilities;

•	natural disasters, geopolitical unrest, war, terrorism and other catastrophes outside of our control; and

•	general economic conditions in domestic or international markets.

Any one of the factors above or the cumulative effect of some of the factors above may result in significant fluctuations in our operating results. As a result, period-to-period comparisons of our operating results may not be

meaningful, and you should not rely on them as an indication of our future performance. The variability and unpredictability of our quarterly operating results or other operating metrics could result in our failure to meet our expectations or those of investors or any analysts that cover us with respect to revenue or other operating results for a particular period. If we fail to meet or exceed such expectations for these or any other reasons, the market price of our common stock could fall substantially.

The success of our business depends 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, and we introduced our first voice-enabled speaker, Sonos One, in October 2017, and our first voice-enabled home theater speaker, Sonos Beam, in July 2018. The voice-enabled speaker market and the voice-enabled smart home systems market are still in the early stages of development. If these 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 expand, 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. We also face intense competition in our markets, and 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 voice-enabled speaker products of their own. For example, Sonos One and Sonos Beam feature voice-control enablement powered by Amazon’s Alexa technology while Amazon currently competes by offering speaker products of its own. As we continue to execute on our product roadmap, our success in introducing voice-enabled speakers that utilize third-party technology, especially voice control, will increasingly depend on the willingness of our technology partners, many of which sell or may develop products that compete with ours, to continue to promote and enhance 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. If these partners disable the integration of their technology into our products, demand for our products may decrease and our sales may be harmed. We cannot assure you that the resources we invest in research and development, existing or alternative technology partnerships, marketing and sales will be adequate for us to successfully establish and maintain a large share of the voice-enabled speaker market. If we are not able to capture and sustain market share, our future revenue growth will be negatively impacted.

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

Due to the highly volatile and 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. The successful introduction of our new products depends on a number of factors, such as the timely completion of development efforts to correspond with limited windows for market introduction. In recent years, we have experienced delays in bringing new products to market, along with higher-than-expected costs in doing so. We face significant challenges in managing the risks associated with new product introductions and production ramp-up issues, including accurately forecasting initial consumer demand, as well as the risk that new products may have quality or other defects in the early stages of introduction. New and upgraded products can also affect the sales and profitability of existing products. In addition, from time to time, we enter into strategic alliances or collaborative partnerships with third parties to develop, commercialize and market new products, which may not be successful or result in significant revenues. Accordingly, if we cannot properly manage the introduction of our new products, our operating results and financial condition may be adversely impacted, particularly if the cadence of new product introductions increases as we expect.

We are highly dependent on a key contract manufacturer to manufacture our products, and while we recently began using additional manufacturers, we may be unable to operate our business if our key contract manufacturer is unable to manufacture our products or ends its relationship with us.

We have historically depended on a single manufacturer, Inventec Appliances Corporation (“Inventec”), to manufacture our products. Recently, we began using additional manufacturers to manufacture certain of our products, though Inventec remains our key manufacturer for the vast majority of our production. Our reliance on Inventec increases the risk that, in the event of an interruption in Inventec’s operations, whether due to a natural catastrophe,

43

Table of contents

labor dispute or otherwise, we would not be able to maintain our production capacity without incurring material additional costs and substantial delays. Additionally, Inventec can terminate its agreement with us for any reason with 180 days’ advance notice. If Inventec breaches or terminates its agreement with us or otherwise fails to perform its obligations in a timely manner, we may be severely delayed or fully prevented from selling our products. If Inventec were unable to perform its obligations or were to end its relationship with us, it would take a significant amount of time to increase our production with other manufacturers or to identify and onboard a new manufacturer that has the capability and resources to build our products to our specifications in sufficient volume. Moreover, a violation of labor, environmental, intellectual property or other laws by our manufacturers, or a failure of our manufacturers to follow generally accepted ethical business practices, could create negative publicity, harm our reputation and require us to contract with new manufacturers. Identifying additional manufacturers would require us to evaluate and approve their quality control systems, technical capabilities, responsiveness, service, financial stability, regulatory compliance and labor and other ethical practices. 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.

We depend on a limited number of third-party components suppliers and logistics providers. Our business may be harmed if these parties do not perform their obligations or if they suffer interruptions to their own operations, or if alternative component sources are unavailable or if there is an increase in the costs of these components.

We are dependent on a limited number of suppliers for various key components used in our products, and the cost, quality and availability of these components are essential to the successful production and sale of our products. We have sole-source suppliers, particularly for product-specific mechanical enclosures, and single-source suppliers, particularly for processor components. We are subject to the risk of shortages and long lead times in the supply of these components and other materials, and the risk that our suppliers discontinue or modify, or increase the price of, the components used in our products. If the supply of these components were to be 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. Further, if there were a shortage of supply, the cost of these components may increase and harm our ability to sell our products on a cost-effective basis. For example, similar to other companies in the electronics industries, we have from time to time experienced shortages of random-access memory that is integral to manufacturing our products. More recently, the global supply of multilayer ceramic capacitors, which are components used across the consumer electronics industry as well as in all of our products, is experiencing shortages due to an imbalance of global demand and supply capacity, resulting in related price increases that we expect will negatively impact our gross margin through calendar year 2019. In connection with any supply shortages in the future, reliable and cost-effective replacement sources may not be available on short notice or at all, and this may result in decreased sales or force us to increase prices and face a corresponding decrease in demand for our products. 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. This would harm our ability to sell our products in order to meet market demand and could materially and adversely affect our brand, image, business prospects and operating results.

We use a small number of logistics providers for substantially all of our product delivery to both distributors and retailers. If one of these providers were to experience financial difficulties or disruptions in its business, our own operations could be adversely affected. Because substantially all of our products are distributed from 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. Our distribution facilities employ computer-controlled and automated equipment, and thus may be vulnerable to computer viruses or other security risks, as well as to electronic or power interruptions or other system failures. Any disruption to the operations of our distribution facilities could delay product delivery, harm our reputation among our customers and adversely affect our operating results and financial condition.

We have limited control over these parties on which our business depends. If any of these parties fails to perform its obligations on schedule, or breaches or ends its relationship with us, we may be unable to satisfy demand for our products. Delays, product shortages and other problems could impair our retail distribution and brand image and make it difficult for us to attract new customers. If we experience significantly increased demand, or if we need to replace an existing supplier or logistics provider, we may be unable to supplement or replace such supply or logistics capacity on terms that are acceptable to us, which may undermine our ability 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. Accordingly, a loss or interruption in the service of any key party could adversely impact our revenue, gross margin and operating results.

Our investments in marketing may not yield the results we expect.

We have made significant investments in marketing our products. Such efforts include direct marketing to consumers to promote awareness of our products, and of our brand in general. These efforts may not yield the results we anticipate and may prove more expensive than we currently anticipate, and revenue may not increase sufficiently to offset these higher expenses. Failures in our marketing efforts could adversely impact our business, financial condition and results of operations.

The home audio and consumer electronics industries are highly competitive. Competition presents an ongoing threat to the success of our business.

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. 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 current and potential competitors have established, or may establish, cooperative relationships among themselves or with third parties in order to increase the abilities of their products to address the needs of our prospective customers, and other companies may enter our markets by acquiring or entering into strategic relationships with our competitors. To remain competitive, we may also need to increase our selling and marketing expenses. We may not have the financial resources, technical expertise or marketing and sales capabilities to continue to compete successfully. A failure to efficiently 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. Such consolidation 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 content partners were to acquire a home audio hardware company, that partner 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.

Conflicts with our distribution and technology 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, which partners have greater financial resources than we do. Amazon and Apple, for example, already offer products that compete with ours. To the extent products offered by our partners compete with our products, they may choose to promote their own products over ours or could end our partnerships and cease selling or promoting our products entirely. If our distribution partners, such as Amazon and Apple, continue to compete with us more directly in the future, they would be able to market and promote their products more prominently than they market and promote our products, and could refuse to promote or offer our products for sale alongside their own, or at all, in distribution channels. 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 in order to promote our products. If we are unable to effectively sell our products due to conflicts with our distribution partners, our business would be harmed.

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 in October 2017

45

Table of contents

and Sonos Beam in July 2018, which are both voice- enabled speakers that feature voice-control enablement powered by Amazon’s Alexa technology. Our current agreement with Amazon allows Amazon to disable the Alexa integration in our Sonos One or Sonos Beam products with limited notice. As such, it is possible that Amazon, which sells products that compete with ours, may on limited notice disable the integration, which would cause our Sonos One or Sonos Beam products to lose their voice-enabled functionality. Amazon could also begin charging us for this integration which would harm our operating results. We are working to establish partnerships with other companies that have developed voice-control enablement technology, but we cannot assure you that we will be successful in doing so. If Amazon does not maintain the Alexa integration, if Amazon seeks to charge us for this integration, if we have not developed alternative partnerships for similar voice-enabled products or if we have not developed such products on our own, our sales may decline, our reputation may be harmed and our business and operating results may suffer.

Competition from our partners who are able to sell speaker products at lower prices could force us to lower our prices, which would harm our operating results.

Many of our current and potential partners have business objectives that may drive them to sell their speaker products at a significant discount to ours. Amazon and Google, for example, both currently offer their speaker products at significantly lower prices than Sonos One and Sonos Beam. 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. Our business model, by contrast, is dependent on the sale of our speakers. Should we be forced to lower the price of our products in order to compete on a price basis, our operating results could be harmed.

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 of our arrangements have been entered into on a royalty-free basis. Some of these content partners compete with us already, and others may in the future produce and sell speakers along with their streaming services. Additionally, other content partners may form stronger alliances with our competitors in the home audio market. Any of our content partners may cease to allow their content to be streamed on our products for a variety of reasons, including to promote other partnerships or their products over our products, or seek to charge us for this streaming. If this were to happen, demand for our products could decrease and our operating results could be harmed.

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 manufacturer, and our ability to do so accurately could be affected by many factors, including an increase or decrease in customer demand for our products or those of our competitors, the success of new products in the market, sales promotions by us or our competitors, channel inventory levels and unanticipated shifts in general economic conditions or consumer confidence levels. Such a rapid increase in production could also cause a decline in manufacturing quality and customer satisfaction. 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 could impair the strength of our brand. In addition, if we were to have excess inventory, we may have reduced working capital, which could adversely affect our ability to invest in other important areas of our business such as marketing and product development. If our channel partners have excess inventory of our products, they may decrease purchase of our products in subsequent periods. If demand exceeds our forecast and we do not have sufficient inventory to meet this demand, we would have to rapidly increase production and suffer higher supply and manufacturing costs that would lower our gross margin. Any of these scenarios could adversely impact our operating results and financial condition.

We experience seasonal demand for our products, and if our sales in high-demand periods are below our forecasts, our overall financial condition and operating results could be adversely affected.

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.

46

Table of contents

We attempt to time our new product releases to coincide with relatively higher consumer spending in the first fiscal quarter, which contributes to this seasonal variation. 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.

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. We cannot assure you that this market will continue to grow. 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. In order to attract and retain customers, these services must continue to attract record labels, artists, other content providers and advertisers and all parties must be able to successfully monetize their streaming-based businesses over the long term. If the development of the streaming music market fails to keep pace with consumer demand expectations, the market for streaming music could decline and our business may be harmed. Additionally, we cannot assure you that the streaming music business model or the streaming music services we partner with will be successful over the long term. If the streaming music market in general declines or if the streaming services we partner with are not successful, demand for our products may suffer and our operating results may be adversely affected.

If we are not successful in expanding 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 are currently investing in our direct-to-consumer sales channel, primarily through our website, and our future growth relies in part on our ability to attract consumers to this channel. We plan to invest in driving sales through this channel. The level of consumer traffic and volume of consumer purchases through our website depends in large part on our ability to provide a user-friendly and visually appealing interface, a seamless consumer experience, sufficient inventory and reliable, timely delivery of our products. Building this channel and improving our website and product delivery services will continue to require significant expenditures in marketing, software development and infrastructure. If we are unable to drive traffic to, and increase sales through, our website, our business and results of operations could be harmed. The success of direct-to-consumer sales through our website is subject to risks associated with e-commerce, including implementing and maintaining appropriate technology and systems, reliance on third-party service providers, data breaches and disruption of internet service. 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.

Additionally, the expansion of our direct-to-consumer channel may alienate some of our channel partners and could 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 or to offer competitive 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.

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. Some of our key channel partners include Best Buy, which accounted for 16% of our revenue in fiscal 2019 , and the ALSO Group, our distributor in Germany, Sweden, Denmark and Norway, which accounted for 11% of our revenue in fiscal 2019 . We do not enter into long-term volume commitments with our major channel partners. If one or several of our channel partners were to discontinue selling our products, increase their promotion of competing products or choose to promote competing products over ours, the volume of our products sold to customers could decrease, which could in turn harm our

business. In addition, the loss of a key channel partner for distribution would require us to identify and contract with alternative channel partners, or to rely more heavily on direct-to-consumer sales, which we may be unable to do successfully, or which could prove time-consuming and expensive. In addition, revenue from our channel partners depends on a number of factors outside our control and may vary from period to period. If one or more of our channel partners were to experience serious financial difficulty as a result of weak economic conditions or otherwise, and were to reduce its inventory of our products or limit or cease operations, our business and results of operations would be significantly harmed. Consolidation of our channel partners in the future or additional concentration of market share among our channel partners may also exacerbate this risk.

Because we compete with many other providers of consumer products for placement and promotion of products in the stores of our channel partners, our success depends on our channel partners and their willingness to promote our products successfully. In general, our contracts with these third parties allow them to exercise significant discretion over the placement and promotion of our products in their stores, and they could give higher priority to other products. Our channel partners may also give their own products or those of our competitors better placement over our products in stores or online. If our channel partners do not effectively market and sell our products, or if they choose to use greater efforts to market and sell their own or our competitors’ products, our business, operating results and prospects may be adversely affected.

A significant disruption in our websites, servers or information technology systems, or those of our third-party partners, or flaws or other vulnerabilities in our products, 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 and to store intellectual property, forecast our business, maintain financial records, manage operations and inventory and operate other critical functions. Accordingly, we rely heavily on the accuracy, capacity and security of both our information technology systems and those of third parties. 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, disruptions or shutdowns due to power outages, hardware failures, structural or operational failures, computer viruses, hacking attacks, telecommunication failures, user error, malfeasance, system upgrades, integration or migration, and other foreseeable and unforeseeable events. All of our products are connected to the internet and receive periodic software updates from our servers and it is possible that such servers could be compromised, resulting in the delivery of malicious code, severely hampering product functionality. System failures and disruptions could impede the manufacturing and shipping of products, delivery of online services, functionality of our products, transactions processing and financial reporting, and could result in the loss of intellectual property or data, require substantial repair costs and damage our reputation and business relationships. Such failures and disruptions could therefore adversely affect 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. Our brand, reputation and ability to retain and attract new customers depend on the reliable performance of our technology and cloud-based content delivery. 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. If we were to experience an AWS service interruption, or if the security of the AWS infrastructure were compromised or believed to have been compromised, our ability to serve our customers and our reputation with current and potential customers would be negatively impacted.

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.

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

Our business relies in part upon the ability of consumers to access high-quality streaming content through the internet. As a result, the growth of our business depends partially on our customers’ ability to obtain low-cost, high-speed internet access, which relies in part on network operators’ continued willingness to upgrade and maintain their equipment as needed to sustain a robust internet infrastructure, as well as their continued willingness to preserve the open and interconnected nature of the internet. We exercise no control over network operators, which makes us vulnerable to any errors, interruptions or delays in their operations. Any material disruption in internet services could harm our business.

To the extent that the number of internet users continues to increase, network congestion could adversely affect the reliability of our platform. We may also face increased costs of doing business if network operators engage in discriminatory practices with respect to streamed audio content in an effort to monetize access to their networks by content providers. 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 effective June 2018. The 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.

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 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. Maintaining, promoting and positioning our brand depends largely on the success of our marketing efforts, the consistency of the quality of our products and our ability to successfully secure, maintain and defend the trademarks that are key to our brand. Each of these objectives requires significant expenditures, and there is no guarantee that we will be able to achieve these objectives successfully. If we fail to successfully maintain, promote and position our brand and protect our reputation, or if we incur significant expenses in this effort, our business, financial condition and operating results may be adversely affected. The value of our brand could also be severely damaged by isolated incidents, particularly if these incidents receive considerable negative publicity or result in litigation, and by events outside of our control. Additionally, 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. The market demand for our products, the value of our brand and our reputation generally could be harmed if any such incidents or other matters erode consumer confidence in us or our products. Any negative effect on our brand, regardless of whether it is within our control, could adversely affect our reputation, business and results of operations.

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

49

---

Table of contents

that we would need to hire additional personnel, partner with new third parties and incur considerable research and development expenses in order to pursue such an expansion successfully. We 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 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 may choose to 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 have grown to 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 in the near to intermediate term, this backward compatibility will no longer be practical or cost-effective, and we may decrease or discontinue service for our older products. If we no longer provide extensive backward capability for our products, we may damage our relationship with our customers, and the value proposition of our products with existing and prospective customers may decline. We may lose existing customers if their older products cannot integrate with newer versions of our software, and this may also result in negative publicity that could adversely affect our reputation and brand loyalty and impact our ability to attract new customers or sell new products to existing customers. For these reasons, any decision to decrease or discontinue backward capability may decrease sales 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 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 of our products, except in the European Union (the “EU”) and select other countries where we provide a two-year warranty on all of our products. The occurrence of any material defects in our products could expose us to liability for damages and 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, if any of our product designs are defective or are alleged to be defective, we may be required to participate in a recall campaign. In part due to the terms of our warranty policy, any failure rate of our products that exceeds our expectations may result in unanticipated losses. Any negative publicity related to the perceived quality of our products could affect our brand image and decrease retailer, distributor and consumer confidence and demand, which could adversely affect our operating results and financial condition. Further, accidental damage coverage and extended warranties are regulated in the United States at the state level and are treated differently within each state. Additionally, outside the United States, regulations for extended warranties and accidental damage vary from country to country. Changes in interpretation of the regulations concerning extended warranties and accidental damage coverage on a federal, state, local or international level may cause us to incur costs or have additional regulatory requirements to meet in the future in order to continue to offer our support services. 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.

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.

As we become a more mature company, we may find our recruiting efforts more challenging. In particular, we have experienced difficulties in recruiting qualified software engineers. The equity incentives we currently use to attract, retain and motivate employees may not be as effective as in the past. We rely heavily on equity incentives to attract and retain employees, and if the value of the underlying common stock does not grow commensurate with expectations, we may not be able to effectively recruit new employees and we may risk losing existing employees. 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.

We may 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, the possibility of intellectual property rights claims against us grows, including the threat of lawsuits from non-practicing entities. 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 litigations and disputes on terms that are unfavorable to us. Similarly, if any litigation to which we may be party fails to settle and we go to trial, we may be subject to an unfavorable judgment that may not be reversible upon appeal. The terms of such a settlement or judgment may require us to cease some or all of 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.

With respect to intellectual property rights claims, we may have to negotiate a license in order to continue practices found to be in violation of a third party’s rights. Any such license may not be available on reasonable terms and may significantly increase our operating expenses, or may not be available to us at all. As a result, we may also be required to develop alternative, non-infringing technology or practices or to discontinue the practices altogether. The development of alternative non-infringing technology or practices could require significant effort and expense and ultimately may not be successful, and our business and results of operations could be materially and 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, third parties may 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, in December 2017, a jury found that Denon had infringed and was infringing certain of our patents, and in May 2018, we settled the remaining claims in exchange for royalty payments from Denon. 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. Additionally, 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 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

51

against could retaliate through non-litigious means, which could harm our ability to compete against such parties or to enter new markets.

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 will likely discover unauthorized products in the marketplace that are counterfeit reproductions of our products. Although we may expend efforts to pursue counterfeiters, it is not practical to pursue all counterfeiters. 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.

Our use of open source software could negatively affect our ability to sell our products and could subject us to possible litigation.

We incorporate open source software into our products, and we may continue to incorporate open source software into our products in the future. Open source software is generally licensed by its authors or other third parties under open source licenses. Some of these licenses contain requirements that we make available source code for modifications or derivative works we create based upon the open source software, and that we license such modifications or derivative works under the terms of a particular open source license or other license granting third parties certain rights of further use. Additionally, if a third-party software provider has incorporated open source software into software that we license from such provider, we could be required to disclose any of our source code that incorporates or is a modification of our licensed software. If an author or other third party that distributes open source software that we use or license were to allege that we had not complied with the conditions of the applicable license, we could be required to incur significant legal expenses defending against those allegations and could be subject to significant damages, enjoined from offering or selling our products that contained the open source software and required to comply with the above conditions. Any of the foregoing could disrupt and harm our business and financial condition.

We collect, store, process and use our customers’ personally identifiable information and other data, which subjects us to governmental regulation and other legal obligations related to privacy, information security and data protection. 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. While our privacy policies currently prohibit such activities, our third-party service providers or partners may engage in such activity without our knowledge or consent. 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. Depending on the nature of the information compromised in a data breach, disruption or other unauthorized access to our customers’ data, we may also have obligations to notify customers about the incident and we may need to provide some form of remedy for the individuals affected. Such breach notification laws continue to develop and may be inconsistent across jurisdictions. Complying with these obligations could cause us to incur substantial costs and negative publicity. While we maintain insurance coverage that is designed to address certain aspects of cyber risks, such insurance coverage may be insufficient to cover all losses or all types of claims that may arise in the event we experience a security breach.

Data protection laws may be interpreted and applied inconsistently from country to country, and often impose requirements that are inconsistent with one another. In addition, because various jurisdictions have different laws and regulations concerning the use, storage and transmission of such information, we may face complex and varied compliance requirements in existing markets as well as in new international markets that we seek to enter. Such laws and regulations, and the variation between jurisdictions, could subject us to elevated costs of security measures, liabilities or negative publicity that could adversely affect our business.

Regulatory scrutiny of privacy, data collection, use of data and data protection is intensifying globally, and the personal information and other data we collect, store, process and use is increasingly subject to legislation and regulations in numerous jurisdictions around the world, especially in Europe. These laws often develop in ways we cannot predict and may materially increase our cost of doing business, particularly as we expand the nature and types of products we offer. For example, the General Data Protection Regulation (the “GDPR”), which came into effect in the EU in May 2018 and superseded prior EU data protection legislation, imposes more stringent data protection requirements and provides for greater penalties for noncompliance. Further, as discussed in more detail below, the United Kingdom has initiated the formal process to leave the EU, creating uncertainty with regard to the regulation of data protection in the United Kingdom. In particular, it is unclear whether the United Kingdom will enact data protection laws or regulations designed to be consistent with the GDPR and how data transfers to and from the United Kingdom will be regulated. Additionally, although we are making use of the EU Standard Contractual Clauses with regard to the transfer of certain personal data to countries outside the European Economic Area (the “EEA”), some regulatory uncertainty remains surrounding the future of data transfers from the EEA to the United States. Although we are closely monitoring regulatory developments in this area, any actual or perceived failure by us to comply with any regulatory requirements or orders or other domestic or international privacy or consumer protection-related laws and regulations could result in proceedings or actions against us by governmental entities or others (e.g., class action litigation), subject us to significant penalties and negative publicity, require us to change our business practices, increase our costs and adversely affect our business.

Data protection legislation is also becoming increasingly common in the United States at both the federal and state level. For example, in June 2018, the State of California enacted the California Consumer Privacy Act of 2018 (the “CCPA”), which will come into effect on January 1, 2020. The CCPA requires companies that process information on California residents to make new disclosures to consumers about their data collection, use and sharing practices, allows consumers to opt out of certain data sharing with third parties and provides a new cause of action for data breaches. However, California legislators have stated that they intend to propose amendments to the CCPA, and it remains unclear what, if any, modifications will be made to the CCPA or how it will be interpreted. Additionally, the Federal Trade Commission and many state attorneys general are interpreting federal and state consumer protection laws to impose standards for the online collection, use, dissemination and security of data. The burdens imposed by the CCPA and other similar laws that may be enacted at the federal and state level may require us to modify our data processing practices and policies and to incur substantial expenditure in order to comply.

Further, we may be or become subject to data localization laws mandating that data collected in a foreign country be processed and stored only within that country. Russia adopted such a law in 2014, and it is expected that China will do so as well. If China or another country in which we have customers were to adopt a data localization law, we could be required to expand our data storage facilities there or build new ones in order to comply. The expenditure this would require, as well as costs of compliance generally, could harm our 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 2019 , 51% 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;

•	political, social and/or economic instability;

•	risks related to governmental regulations in foreign jurisdictions and unexpected changes in regulatory requirements and enforcement;

•	higher levels of credit risk and payment fraud;

•	burdens of complying with a variety of foreign 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;

•	tariffs, trade barriers and duties;

53

Table of contents

•	reduced protection for intellectual property rights in some countries;

•	difficulties in staffing and managing global operations and the increased travel, infrastructure and legal compliance costs associated with having multiple international locations;

•	compliance with statutory equity requirements;

•	potential negative consequences from changes in or interpretations of U.S. and foreign tax laws;

•	protectionist laws and business practices that favor local businesses in some countries;

•	imposition of currency exchange controls;

•	greater fluctuations in sales to customers in developing countries, including longer payment cycles and greater difficulty collecting accounts receivable; 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. These factors may also harm our results of operations. 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.

In particular, we have significant operations in China, where many of the risks listed above are particularly acute. Our business, financial condition and results of operations may be materially adversely affected by economic, political, legal, regulatory, competitive and other factors in China. The Chinese economy differs from the economies of most developed countries in many respects, including the level of government involvement and control over economic growth. In addition, our operations in China are governed by Chinese laws, rules and regulations, some of which are relatively new. The Chinese legal system continues to rapidly evolve, which may result in uncertainties with respect to the interpretation and enforcement of Chinese laws, rules and regulations that could have a material adverse effect on our business. China also experiences high turnover of direct labor due to the intensely competitive and fluid market for labor, and the retention of adequate labor may be a challenge for our operations in China. 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.

If significant tariffs or other restrictions are placed on Chinese imports or any related counter-measures are taken by China, our revenue and results of operations may be materially harmed.

If significant tariffs or other restrictions are placed on Chinese imports or any related counter-measures are taken by China, our revenue and results of operations may be materially harmed. Between July and September 2018, the U.S. Trade Representative imposed tariffs of 10% on a variety of goods imported from China, which may increase to 25% in 2019 pending negotiations between the U.S. and China. Some of these tariffs currently affect our accessories products and we may be required to raise our prices on those products due to the tariffs, which may result in a loss of customers and harm our operating performance. If the existing tariffs are expanded or interpreted by a court or governmental agency to apply to any of our other products, we may be required to raise our prices on those products, which may further result in a loss of customers and harm our operating performance. Additionally the Trump Administration continues to signal that it may further alter trade agreements and terms between China and the United States, including limiting trade with China, and may impose additional tariffs on imports from China. It is possible further tariffs will be imposed on imports of our products, or that our business will be impacted by retaliatory trade measures taken by China or other countries in response to existing or future tariffs, causing us to raise prices or make changes to our operations, any of which could materially harm our revenue or operating results. We may seek to 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 a new supply chain, identifying substitute components and establishing new manufacturing locations.

We are susceptible to fluctuations in foreign currency exchange rates, which could result in declines in our reported revenue and operating results.

Our exposure to the effects of fluctuations in foreign currency exchange rates has grown with the continued expansion of our overseas operations, and primarily relates to non-U.S. dollar denominated sales and operating expenses worldwide. Unfavorable movement in currency exchange rates will adversely affect our results of operations and financial condition. While a significant percentage of our revenue is denominated in foreign currencies, the majority of our costs are denominated in U.S. dollars. This means that a strengthening of the U.S. dollar would adversely impact our reported financial results. The strengthening of foreign currencies may also increase our cost of product components denominated in those currencies, thus adversely affecting gross margin. Fluctuations in currency exchange rates may also make it more difficult to detect underlying trends in our business and results of operations. We may in the future engage in some hedging activities, such as the use of foreign currency forward and option contracts, to limit the risk of fluctuations in currency exchange rates. However, the use of such hedging activities may not offset any, or more than a portion, of the adverse financial effects of unfavorable movements in foreign exchange rates over the limited time the hedges are in place. Moreover, the use of hedging instruments may introduce additional risks if we are unable to structure effective hedges with such instruments. In addition, a strengthening of the U.S. dollar may increase the cost of our products to our customers outside of the United States, which may also adversely affect our financial condition and results of operations.

The decision by British voters to exit the European Union may negatively impact our operations.

In June 2016, a majority of voters in the United Kingdom elected to withdraw from the European Union (often referred to as Brexit) in a national referendum. As of the date of this Annual Report, the British Parliament has not agreed upon the terms of the withdrawal. On April 10, 2019, the leaders of the other member countries of the European Union agreed to extend the deadline for Brexit until October 31, 2019. The referendum and ongoing negotiations have created significant uncertainty about the future relationship between the United Kingdom and the European Union.

If the United Kingdom leaves the European Union with no agreement, it will likely have an adverse impact on labor and trade in addition to creating further short-term uncertainty and currency volatility. In the absence of a future trade deal, the United Kingdom’s trade with the European Union and the rest of the world would be subject to tariffs and duties set by the World Trade Organization. Any adjustments we make to our business and operations as of Brexit could result in significant time and expense to complete.

Any impact from Brexit on our business and operations over the long term will depend, in part, on the outcome of tariff, tax treaties, trade, regulatory, and other negotiations the United Kingdom conducts.

Natural disasters, geopolitical unrest, war, terrorism, 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 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 or 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, 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 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, 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. If there is a new regulation, or change to an existing regulation, that significantly increases our costs of manufacturing or causes us to significantly alter the way that we manufacture our products, this would have a material adverse effect on our business, financial condition and results of operations. Additionally, while we have implemented policies and procedures designed to ensure compliance with applicable laws and regulations, there can be no assurance that our employees, contractors and agents will not violate such laws and regulations or our policies and procedures.

We are subject to the Foreign Corrupt Practices Act (the “FCPA”), and our failure to comply with the laws and regulations thereunder could result in penalties which could harm our reputation, business and financial condition.

Due to our international operations, we are subject to the FCPA, which generally prohibits companies and their intermediaries from making improper payments to foreign officials for the purpose of obtaining or keeping business. The FCPA also requires companies to maintain adequate recordkeeping and internal accounting practices to accurately reflect transactions. Under the FCPA, U.S. companies may be held liable for actions taken by their strategic or local partners or representatives. The FCPA and similar laws in other countries can impose civil and criminal penalties for violations. If we do not properly implement practices and controls with respect to compliance with the FCPA and similar laws, or if we fail to enforce those practices and controls properly, we may be subject to regulatory sanctions, including administrative costs related to governmental and internal investigations, civil and criminal penalties, injunctions and restrictions on our business activities, all of which could harm our reputation, business and financial condition.

Our corporate tax rate may increase, we may incur additional income tax liabilities and 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 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. While we believe we are in compliance with local laws, there is no assurance that tax and customs authorities agree with our reporting positions and upon audit may assess us additional taxes, duties, interest and penalties. If this occurs and we cannot successfully defend our position, our profitability will be reduced.

Our ability to use our net operating loss carryforwards and certain other tax attributes may be limited.

As of September 29, 2018 , we had gross U.S. federal net operating loss carryforwards of $ 74.7 million, which expire beginning in 2033 , and gross state net operating loss carryforwards of $ 45.9 million, which expire beginning in 2020 , as well as $ 21.1 million in foreign net operating loss carryforwards, of which $ 2.1 million have an indefinite life. Also as of September 29, 2018 , we had U.S. federal and state research and development tax credit carryforwards

56

Table of contents

of $ 25.4 million and $ 19.1 million, respectively. The federal research credits will begin to expire in the year 2025 , and the state research credits will begin to expire in 2024 .

 

It is possible that we will not generate taxable income in time to use our net operating loss carryforwards before their expiration or at all. Under Sections 382 and 383 of the Internal Revenue Code of 1986, as amended (the “Code”), if a corporation undergoes an “ownership change,” the corporation’s ability to use its pre-change net operating loss carryforwards and other pre-change attributes, such as research tax credits, to offset its post-change income may be limited. In general, an “ownership change” will occur if there is a cumulative change in ownership by “5-percent shareholders” that exceeds 50 percentage points over a rolling three-year period. Similar rules may apply under state tax laws. As a result, our net operating losses generated through July 18, 2012 may be subject to limitation under Section 382 of the Code. The amount of pre-change loss carryforward which may be subject to this limitation is $46.8 million. Our ability to use net operating loss carryforwards and other tax attributes to reduce future taxable income and liabilities may be subject to limitations based on the ownership change of 2012. We have completed an updated Section 382 study through March 30, 2019, and the results of this study show no ownership change within the meaning of Section 382 of the Code had occurred from the previously identified ownership change on July 18, 2012 through March 30, 2019. We will continue to monitor prospective ownership changes within the meaning of Section 382.

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 credit facilities and net proceeds from the sale of our equity securities. 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 may make investments in complementary businesses, products, services or technologies. We have not made any material acquisitions to date and, as a result, our ability as an organization to successfully acquire and integrate other companies, products, services or technologies is unproven. We may not be able to find suitable acquisition candidates and we may not be able to complete acquisitions on favorable terms, if at all. If we do complete acquisitions, we may not ultimately strengthen our competitive position or achieve our goals, and any acquisitions we complete could be viewed negatively by customers or investors. In addition, if we fail to integrate successfully such acquisitions, or the technologies associated with such acquisitions, into our company, the revenue and operating results of the combined company could be adversely affected. Any integration process will require significant time and resources, and we may not be able to manage the process successfully. We may not successfully evaluate or utilize the acquired technology and accurately forecast the financial impact of an acquisition transaction, including accounting charges. We may have to pay cash, incur debt or issue equity securities to pay for any such acquisition, any of which could affect our financial condition or the value of our capital stock. The sale of equity or issuance of debt to finance any such acquisitions could result in dilution to our stockholders. The incurrence of indebtedness would result in increased fixed obligations and could also include covenants or other restrictions that would impede our ability to manage our operations. Additionally, we may receive indications of interest from other parties interested in acquiring some or all of our business. The time required to evaluate such indications of interest could require significant attention from management, disrupt the ordinary functioning of our business and adversely affect our operating results.

We will need to improve our financial and operational systems in order 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, improve the coordination between our various corporate functions and expand, train and manage our workforce adequately. Our efforts to manage the expansion of our operations may place a significant strain on our management personnel, systems and resources, particularly given the limited amount of financial resources and skilled employees that may be available at the time. When implementing new or changing existing processes, we may encounter transitional

57

issues and incur substantial additional expenses. We cannot be certain that we will institute, in a timely manner or at all, the improvements to our managerial, operational and financial systems and procedures necessary to support our anticipated increased levels of operations. Delays or problems associated with any improvement or expansion of our operational and financial systems could adversely affect our relationships with our suppliers, manufacturers, resellers and customers, cause harm to our reputation and result in errors in our financial and other reporting, any of which could harm our business and operating results. We may not be able to manage our growth effectively, and as a result may not be able to take advantage of market opportunities, execute on expansion strategies or meet the demands of our customers. In particular, we anticipate that our legacy enterprise resource management system will need to be replaced in the near to intermediate term in order to accommodate our expanding operations. Such transitions can prove difficult and time consuming and could adversely impact our business and ability to timely prepare our external financial reports.

We have identified material weaknesses in our internal control over financial reporting and, if our remediation of these material weaknesses is not effective, or if we fail to maintain an effective system of internal control over financial reporting in the future, we may not be able to accurately or timely report our financial condition or results of operations, which may adversely affect investor confidence and the price of our common stock.

As a public company, we will be required to maintain internal control over financial reporting and to evaluate and determine the effectiveness of our internal control over financial reporting. Beginning with our second annual report on Form 10-K following our IPO, we will be required to provide a management report on internal control over financial reporting, as well as an attestation on our internal control over financial reporting from our independent registered public accounting firm.

During 2017, we identified material weaknesses in our internal control over financial reporting. A material weakness is a deficiency, or combination of deficiencies, in internal control over financial reporting such that there is a reasonable possibility that a material misstatement of a company’s annual or interim financial statements will not be prevented or detected on a timely basis. We identified a material weakness related to an insufficient complement of experienced personnel with the requisite technical knowledge of financial statement disclosures and accounting for non-routine, unusual or complex events and transactions. This material weakness in our control environment contributed to an additional material weakness in that we did not maintain effective internal controls to address the accounting of non-routine, unusual or complex events and transactions and the related financial statement presentation of such transactions.

We are taking steps to address these control issues, including the following:

•	hiring of experienced additional accounting and financial reporting personnel; and

•	creation of additional controls including those designed to strengthen our review processes around financial statement disclosures and accounting for non-routine, unusual or complex transactions.

While we believe that these efforts will improve our internal control over financial reporting, the implementation of these measures is ongoing and will require validation and testing of the design and operating effectiveness of internal controls over a sustained period of financial reporting cycles.

We cannot assure you that the measures we have taken to date, and that we are continuing to implement, will be sufficient to remediate the material weaknesses we have identified or avoid the identification of additional material weaknesses in the future. If the steps we take do not remediate the material weaknesses in a timely manner, there could continue to be a reasonable possibility that these control deficiencies or others could result in a material misstatement of our annual or interim consolidated financial statements that would not be prevented or detected on a timely basis.

The process of designing and implementing internal control over financial reporting required to comply with the disclosure and attestation requirements of Section 404 of the Sarbanes-Oxley Act (“Section 404”) will be time consuming and costly. If during the evaluation and testing process, we identify additional material weaknesses in our internal control over financial reporting or determine that existing material weaknesses have not been remediated, our management will be unable to assert that our internal control over financial reporting is effective. Even if our management concludes that our internal control over financial reporting is effective, our independent registered public accounting firm may conclude that there are material weaknesses with respect to our internal control over financial reporting. If we are unable to assert that our internal control over financial reporting is effective, or when required

Table of contents

in the future, if our independent registered public accounting firm is unable to express an unqualified opinion as to the effectiveness of our internal control over financial reporting, investors may lose confidence in the accuracy and completeness of our financial reports, the market price of our common stock could be adversely affected and we could become subject to litigation or investigations by The Nasdaq Stock Market, the SEC or other regulatory authorities, which could require additional financial and management resources.

Our reported financial results may be adversely affected by changes in accounting principles generally accepted in the United States.

Generally accepted accounting principles in the United States are subject to interpretation by the Financial Accounting Standards Board, the American Institute of Certified Public Accountants, the SEC and various bodies formed to promulgate and interpret appropriate accounting principles. A change in these principles or interpretations could have a significant effect on our reported financial results, and could affect the reporting of transactions completed before the announcement of a change.

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 market 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 $ 9.58 to $ 21.69 through May 6, 2019 . The market 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 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; and

•	sales of shares of our common stock by us or our stockholders.

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 market prices of 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.

Our business and financial performance may differ from any projections that we disclose or any information that may be attributed to us by third parties.

From time to time, we may provide guidance via public disclosures regarding our projected business or financial performance. However, any such projections involve risks, assumptions and uncertainties and our actual results could

59

Table of contents

differ materially from such projections. Factors that could cause or contribute to such differences include, but are not limited to, those identified in these Risk Factors, some or all of which are not predictable or within our control. Other unknown or unpredictable factors also could adversely impact our performance, and we undertake no obligation to update or revise any projections, whether as a result of new information, future events or otherwise. In addition, various news sources, bloggers and other publishers often make statements regarding our historical or projected business or financial performance, and you should not rely on any such information even if it is attributed directly or indirectly to us.

Our stock price and trading volume could decline if securities or industry analysts do not publish about our business, or if they publish unfavorable research.

Equity research analysts do not currently provide coverage of our common stock, and we cannot assure that any equity research analysts will adequately provide research coverage of our common stock. A lack of adequate research coverage may harm the liquidity and market price of our common stock. To the extent equity research analysts do provide research coverage of our common stock, we will not have any control over the content and opinions included in their reports. The price of our common stock could decline if one or more equity research analysts downgrade our stock or publish other unfavorable commentary or research. Moreover, if one or more equity research analysts cease coverage of our company, or fail to regularly publish reports on us, the demand for our common stock could decrease, which in turn could cause our stock price or trading volume to decline.

Sales of a substantial amount of our common stock in the public market, particularly sales by our directors, executive officers and significant stockholders, or the perception that these sales could occur, could cause the market price of our common stock to decline.

Sales of a substantial number of shares of our common stock in the public market, particularly sales by our directors, executive officers and principal stockholders, or the perception that these sales might occur, could cause the market price of our common stock to decline. All of the outstanding shares of our common stock are freely tradable in the public market without restrictions or further registration, except for any shares held by our affiliates, as defined in Rule 144 under the Securities Act of 1933, as amended (the “Securities Act”). Shares held by directors, executive officers, and other affiliates are also subject to volume limitations under Rule 144 under the Securities Act and various vesting agreements, as well as our insider trading policy.

In addition, we have filed a registration statement to register shares reserved for future issuance under our equity compensation plans. Subject to the satisfaction of applicable vesting requirements, the shares issued upon exercise of outstanding stock options will be available for immediate resale in the United States in the open market.

Moreover, certain holders of our common stock have rights, subject to some conditions, to require us to file registration statements for the public resale of such shares or to include such shares in registration statements that we may file for us or other stockholders.

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 of 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.

Additional stock issuances could result in significant dilution to our stockholders.

We may also issue our shares of common stock or securities convertible into shares of our common stock from time to time in connection with a financing, acquisition, investments or otherwise. Additional issuances of our capital stock will result in dilution to our existing stockholders. We also grant equity awards to employees, directors and consultants under our 2018 Equity Incentive Plan and rights to purchase our common stock under our 2018 Employee Stock Purchase Plan, the latter of which will become effective at a future date upon determination by the compensation committee of the Board. Also, to the extent outstanding options and rights to purchase our capital stock are exercised and restricted stocks units vest and are settled, there will be further dilution. The amount of dilution could be substantial

depending upon the size of the issuance or exercise, which may cause the market price of our common stock to decline.

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, and the market price of our common stock may be lower as a result.

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 to fill any vacancies and newly created directorships;

•	a requirement that our directors may only be removed for cause;

•	a prohibition on cumulative voting for directors;

•	the requirement of a super-majority to amend some provisions in our restated certificate of incorporation and restated bylaws;

•	authorization of the issuance of “blank check” preferred stock that the Board could use to implement a stockholder rights plan;

•	an inability of our stockholders to call special meetings of stockholders; and

•	a prohibition on stockholder actions by written consent, thereby requiring that all stockholder actions be taken at a meeting of our stockholders.

In addition, our restated certificate of incorporation provides that the Delaware Court of Chancery is the exclusive forum for any derivative action or proceeding brought on our behalf; any action asserting a breach of fiduciary duty; any action asserting a claim against us arising pursuant to the Delaware General Corporation Law (the “DGCL”), our restated certificate of incorporation or our restated bylaws; or any action asserting a claim against us that is governed by the internal affairs doctrine.

Our restated certificate of incorporation also provides that the federal district courts of the United States will be the exclusive forum for resolving any complaint asserting a cause of action arising under the Securities Act (the “Federal Forum Provision”). In December 2018, the Delaware Court of Chancery found that provisions such as the Federal Forum Provision are not valid under Delaware law. In light of this decision of the Delaware Court of Chancery, we do not intend to enforce the Federal Forum Provision in our restated certificate of incorporation unless and until such time there is a final determination by the Delaware Supreme Court regarding the validity of provisions such as the Federal Forum Provision. To the extent the Delaware Supreme Court makes a final determination that provisions such as the Federal Forum Provision are not valid as a matter of Delaware law, the Board intends to amend our restated certificate of incorporation to remove the Federal Forum Provision.

In addition, because we are incorporated in Delaware, we are governed by the provisions of Section 203 of the DGCL, which prohibit a person who owns 15% or more of our outstanding voting stock from merging or combining with us for a three-year period beginning on the date of the transaction in which the person acquired in excess of 15% of our outstanding voting stock, unless the merger or combination is approved in a prescribed manner. Any provision in our restated certificate of incorporation, our restated bylaws or Delaware law that has the effect of delaying or deterring a change in control could limit the opportunity for our stockholders to receive a premium for their shares of our common stock, and could also affect the price that some investors are willing to pay for our common stock.
