Forward-looking statements are subject to a number of risks and uncertainties, many of which involve factors or circumstances that are beyond the Company’s control. The Company’s actual results could differ materially from those stated or implied in forward-looking statements due to a number of factors, including but not limited to: our ability to acquire new customers, our ability to sustain and/or manage our growth, our ability to increase our total net revenue per active customer, our ability to build and maintain strong brands and other risks detailed in the Company’s other publicly available filings with the Securities and Exchange Commission.

EXPLANATORY NOTE

The consolidated and condensed financial statements and other disclosures contained in this earnings release are those of Wayfair Inc. Prior to the effectiveness of Wayfair’s registration statement on Form S-1 related to its initial public offering in October 2014, Wayfair LLC was the principal operating entity. In connection with the initial public offering of Wayfair Inc., Wayfair LLC completed a corporate reorganization pursuant to which Wayfair LLC became a wholly-owned subsidiary of Wayfair Inc., and the holders of equity interests in Wayfair LLC became stockholders of Wayfair Inc.

Non-GAAP Financial Measures

To supplement Wayfair’s unaudited consolidated and condensed financial statements presented in accordance with generally accepted accounting principles (“GAAP”), this earnings release and the accompanying tables and the related earnings conference call contain certain non-GAAP financial measures, including Adjusted EBITDA, Adjusted EBITDA as a percentage of total net revenue (“Adjusted EBITDA Margin”), free cash flow and non-GAAP net loss and diluted net loss per share. Wayfair uses these non-GAAP financial measures internally in analyzing its financial results and believes they are useful to investors, as a supplement to GAAP measures, in evaluating Wayfair’s ongoing operational performance. Wayfair has provided a reconciliation of these non-GAAP financial measures to the most directly comparable GAAP financial measure in this earnings release.

Adjusted EBITDA and Adjusted EBITDA Margin are non-GAAP financial measures that are calculated as earnings (loss) before depreciation and amortization, equity-based compensation and related taxes, interest and other income and expense and provision for income taxes. Wayfair has included Adjusted EBITDA and Adjusted EBITDA Margin in this earnings release because they are key measures used by its management and its board of managers to evaluate its operating performance, generate future operating plans and make strategic decisions regarding the allocation of capital. In particular, the exclusion of certain expenses in calculating Adjusted EBITDA and Adjusted EBITDA Margin facilitate operating performance comparisons on a period-to-period basis and, in the case of exclusion of the impact of equity-based compensation and related taxes, excludes an item that we do not consider to be indicative of our core operating performance. Investors should, however, understand that equity-based compensation will be a significant recurring expense in our business and an important part of the compensation provided to our employees. Accordingly, Wayfair believes that Adjusted EBITDA and Adjusted EBITDA Margin provide useful information to investors and others in understanding and evaluating our operating results in the same manner as our management and board of managers.

Free cash flow is a non-GAAP financial measure that is calculated as net cash (used in) provided by operating activities less net cash used to purchase property and equipment including leasehold improvements and site and software development costs. Wayfair believes free cash flow is an important indicator of Wayfair’s business performance, as it measures the amount of cash it generates. Accordingly, Wayfair believes that free cash flow provides useful information to investors and others in understanding and evaluating its operating results in the same manner as its management.

Non-GAAP diluted net loss per share is a non-GAAP financial measure that is calculated as GAAP net loss attributable to common stockholders plus accretion of convertible redeemable preferred units, equity-based compensation and related taxes and provision for income taxes divided by weighted average shares. Wayfair believes that adding back accretion of convertible redeemable preferred units, equity-based compensation expense and related tax and provision for income taxes as adjustments to its GAAP diluted net loss before calculating per share amounts for all periods presented provides a more meaningful comparison between our operating results from period to period.

Wayfair does not itself, nor does it suggest that investors should, consider such non-GAAP financial measures in isolation from, or as a substitute for, financial information prepared in accordance with GAAP. Investors should also note that the non-GAAP financial measures used by Wayfair may not be the same non-GAAP financial measures, and may not be calculated in the same manner, as that of other companies, including other companies in its industry.
