First Quarter 2018 Guidance

We expect limited revenue from new product introduction. With consumer demand shifting towards smartwatches, we expect revenue to decline approximately (20%) to (15%) year over year and to be in a range of $240 million to $255 million .

. Non-GAAP basic net loss per share in the range of ($0.21) to ($0.18) .

. Capital expenditures as a percentage of revenue of approximately 8%.

We expect free cash flow to decline less than revenue, as receivables turn into cash receipts and less overhead is required to support the growth in inventory, and anticipate free cash flow of approximately $(25) million .

. Effective non-GAAP tax rate of approximately 40%.

Stock-based compensation expense of approximately $26 million and basic share count of approximately 240 million.

Full Year 2018 Guidance

We expect our device mix to continue to shift towards smartwatches over the course of the year. We expect to grow Fitbit Health Solutions and increase premium subscribers, but this growth will be relatively immaterial to wearable device revenue. We extrapolated the demand trend forecasted in the first quarter 2018 for the full year and expect revenue to be approximately $1.5 billion .

. We expect device mix shift and fixed cost deleveraging to negatively impact gross margins, partially offset by operating efficiencies.

We expect to drive operating expenses 7% lower, to a target of $740 million .

. Capital expenditures as a percentage of revenue of approximately 3.5%.

We expect free cash flow to decline less than revenue and expect to breakeven for 2018. Guidance excludes the benefit of an expected $80 million tax refund payment.

tax refund payment. We expect effective non-GAAP tax rate to be volatile driven by geographic mix of revenue, tax credits, and shift to profitability.

Stock-based compensation expense of approximately $110 million and basic/diluted share count of approximately 248/267 million.

Forward Looking Statements

This press release contains forward-looking statements that involve risks and uncertainties, including statements regarding our outlook for the first quarter 2018 and full year 2018; our ability to leverage our operating system and SDK for future product launches, our user experience; our expected revenue from new product introductions and expected trends in average selling price, operating expenses, device mix, capital expenditures, free cash flow, and effective non-GAAP tax rate; our expected growth of Fitbit Health Solutions; and consumer demand for smartwatches and connected health and fitness trackers. These forward-looking statements are only predictions and may differ materially from actual results due to a variety of factors, including: the effects of the highly competitive market in which we operate, including competition from much larger technology companies; our ability to anticipate and satisfy consumer preferences in a timely manner; our ability to successfully develop and timely introduce new products and services or enhance existing products and services; retail and customer acceptance of existing and new products; any inability to accurately forecast consumer demand and adequately manage our inventory; our ability to ship products on the timelines we anticipate and unexpected delays; our ability to detect, prevent or fix quality issues in our products or services; uncertain ability to retain employees; our reliance on third-party suppliers, contract manufacturers, and logistics providers, and our limited control over such parties; delays in procuring components and product from these third parties or their suppliers; the ability of third parties to successfully manufacture and ship in a timely manner quality products; seasonality; product liability issues, security breaches or other defects, which may adversely affect product performance, our reputation and brand awareness and overall market acceptance of our products and services; ability to integrate acquired technologies and employees into our operations, particularly in new geographies; warranty claims; the fact that the market for connected health and fitness devices is relatively new and unproven; the ability of our channel partners to sell our products; litigation and related costs; privacy; and other general market, political, economic and business conditions.

Additional risks and uncertainties that could affect our financial results are included under the caption “Risk Factors” in our Annual Report on Form 10-K for the full year ended December 31, 2016 , and our most recently filed Quarterly Report on Form 10-Q which are available on our Investor Relations website at investor.fitbit.com and on the SEC website at www.sec.gov.

Disclosure of Material Information

Fitbit announces material information to its investors using SEC filings, press releases, public conference calls and on its Investor Relations page on the company’s website at http://investor.fitbit.com.

Non-GAAP Financial Measures

To supplement our consolidated financial statements, which are prepared and presented in accordance with GAAP, we use the following non-GAAP financial measures in this press release: non-GAAP gross profit, non-GAAP gross margin, non-GAAP operating expenses, non-GAAP operating income (loss), non-GAAP net income (loss), non-GAAP diluted net income (loss) per share, adjusted EBITDA, non-GAAP free cash flow and non-GAAP income (loss) before income taxes. The presentation of these financial measures is not intended to be considered in isolation or as a substitute for, or superior to, financial information prepared and presented in accordance with GAAP.

We use non-GAAP measures to internally evaluate and analyze financial results. We believe these non-GAAP financial measures provide investors with useful supplemental information about the financial performance of our business, enable comparison of financial results between periods where certain items may vary independent of business performance, and enable comparison of our financial results with other public companies, many of which present similar non-GAAP financial measures.

There are limitations associated with the use of non-GAAP financial measures as an analytical tool. In particular, many of the adjustments to our GAAP financial measures reflect the exclusion of certain items, specifically stock-based compensation expense, depreciation, amortization of intangible assets, interest income (expense), net and the related income tax effects of the aforementioned exclusions, that are recurring and will be reflected in our financial results for the foreseeable future. In addition, these measures may be different from non-GAAP financial measures used by other companies, limiting their usefulness for comparison purposes. A reconciliation of our non-GAAP financial measures to their most directly comparable GAAP measures has been provided in the financial statement tables included in this press release, and investors are encouraged to review the reconciliation.

Guidance for non-GAAP financial measures excludes Jawbone litigation costs, stock-based compensation, impact of restructuring, amortization of acquired intangible assets, and tax effects associated with these items. We have not reconciled guidance for non-GAAP financial measures to their most directly comparable GAAP measures because certain items that impact these measures are uncertain, out of our control and/or cannot be reasonably predicted. Accordingly, a reconciliation of the non-GAAP financial measure guidance to the corresponding GAAP measures is not available without unreasonable effort.

The following are explanations of the adjustments that are reflected in one or more of our non-GAAP financial measures:

Stock-based compensation expense relates to equity awards granted primarily to our employees. We exclude stock-based compensation expense because we believe that the non-GAAP financial measures excluding this item provide meaningful supplemental information regarding operational performance. In particular, companies calculate stock-based compensation expense using a variety of valuation methodologies and subjective assumptions.

In January 2017 , the Company conducted a reorganization of its business, including a reduction in workforce. The restructuring costs impacted our results for the first quarter of 2017. Restructuring costs primarily included severance-related costs. We believe that excluding this expense provides greater visibility to the underlying performance of our business operations, facilitates comparison of our results with other periods, and may also facilitate comparison with the results of other companies in our industry.

We believe that excluding this expense provides greater visibility to the underlying performance of our business operations, facilitates comparison of our results with other periods, and may also facilitate comparison with the results of other companies in our industry. Litigation expense relates to legal costs incurred due to litigation with Aliphcom, Inc. d/b/a Jawbone. We exclude these expenses because we do not believe these expenses have a direct correlation to the operations of our business and because of the singular nature of the claims underlying the Jawbone litigation matters. We began excluding Jawbone litigation costs in the second quarter of 2016 as these costs significantly increased in 2016, and may continue to be material for the remainder of 2017. Although not excluded in reporting for the first quarter of 2016, these litigation expenses were $9.1 million in that quarter.

Although not excluded in reporting for the first quarter of 2016, these litigation expenses were in that quarter. In March 2014 , we recalled the Fitbit Force after some of our users experienced allergic reactions to adhesives in the wristband. This recall primarily impacted our results for the fourth quarter of 2013, the first quarter of 2014 and the fourth quarter of 2015.

, we recalled the Fitbit Force after some of our users experienced allergic reactions to adhesives in the wristband. This recall primarily impacted our results for the fourth quarter of 2013, the first quarter of 2014 and the fourth quarter of 2015. Amortization of intangible assets relates to our acquisition of FitStar, Pebble and Vector. We exclude these amortization expenses because we do not believe these expenses have a direct correlation to the operation of our business.

Income tax effect of non-GAAP adjustments relates to the tax effect of the adjustments that we incorporate into non-GAAP financial measures such as stock-based compensation, amortization of intangibles, restructuring and valuation allowance in order to provide a more meaningful measure of non-GAAP net income (loss).
