EXPLANATORY NOTE

The condensed consolidated 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 an internal restructuring 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 condensed consolidated 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, free cash flow, non-GAAP diluted net loss per share and non-GAAP diluted net loss per share adjusted for shares issued and shares converted at the IPO.  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 is a non-GAAP financial measure that is calculated as earnings (loss) before depreciation and amortization, equity-based compensation and related taxes, interest and other income and expense and taxes. Wayfair has included Adjusted EBITDA in this earnings release because it is a key measure 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 facilitates 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 provides 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 divided by non-GAAP weighted average shares.  Wayfair believes that adding back accretion of convertible redeemable preferred units, equity-based compensation expense and related tax 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. For the fourth quarter of 2014 and full year 2014, Wayfair has included non-GAAP diluted net loss per share on a pro forma basis and assumes the conversion of all outstanding preferred stock, the

issuance of common stock at its IPO in October 2014 along with the vesting of restricted shares and restricted share units, net of applicable taxes, as if these events all occurred at the beginning of the respective periods and presented as such only for three months and full year ended December 31, 2014.  As a result of significant changes to Wayfair’s capital structure in the most recent quarter, Wayfair believes that the presentation of the non-GAAP diluted net loss per share on a pro forma basis provides useful information to investors and others.

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.

The following table reflects the reconciliation of net loss to Adjusted EBITDA for each of the periods indicated:

A reconciliation of GAAP net loss attributable to common stockholders to non-GAAP diluted net loss attributable to common stockholders, the most directly comparable GAAP financial measure, and GAAP diluted common shares to non-GAAP diluted shares, the most directly comparable GAAP financial measure, in order to calculate non-GAAP diluted net loss per share, is as follows:

(1)  Weighted average shares used to compute non-GAAP diluted net loss per share for the three and twelve months ended December 31, 2014 includes the impact of share issuances and share converstions at its IPO and through December 31, 2014 as if they ocurred at the beginning of the 2014 periods presented.

The following table presents a reconciliation of free cash flow to net cash provided by operating activities for each of the periods indicated:
