Forward Looking Statements

This release may contain projections or other forward-looking statements regarding future events or our future financial performance or estimates regarding third parties. These statements are only estimates or predictions and reflect our current beliefs and expectations. Actual events or results may differ materially from those contained in the estimates, projections or forward-looking statements. It is routine for internal projections and expectations to change as the quarter progresses, and therefore it should be clearly understood that the internal projections and beliefs upon which we base our expectations may change prior to the end of the quarter. Although these expectations may change, we will not necessarily inform you if they do. Our policy is to provide expectations not more than once per quarter, and not to update that information until the next quarter. Some of the factors that could cause actual results to differ materially from the forward-looking statements contained herein include, without limitation, (i) our operating results may fluctuate, are difficult to predict and could fall below expectations, (ii) our business depends on strong brands, and failing to maintain and enhance our brands would hurt our business, (iii) our ongoing investment in new businesses and new products, services, and technologies is inherently risky, and could disrupt our ongoing business and/or fail to generate the results we are expecting, (iv) if we are unable to continue to develop solutions that generate revenue from advertising and other services delivered to mobile devices, our business could be harmed, (v) we face intense competition in our markets. If we do not continue to innovate and provide products and services that are useful to users, we may not remain competitive, and our revenue and results of operations could be adversely affected, (vi) our businesses could be negatively affected by changes in Internet search engine algorithms and email marketing policies, (vii) our transactions business is dependent on third-party participants, whose lack of performance could adversely affect our results of operations, (viii) fraudulent or unlawful activities on our marketplace could harm our business and consumer confidence in our marketplace, (ix) we may be subject to legal liability associated with providing online services or content, (x) we may be unable to continue to use the domain names that we use in our business, or prevent third parties from acquiring and using domain names that infringe on, are similar to, or otherwise decrease the value of our brand or our trademarks or service marks, and (xi) other factors detailed in documents we file from time to time with the Securities and Exchange Commission. Forward-looking statements in this release are made pursuant to the safe harbor provisions contained in the Private Securities Litigation Reform Act of 1995.

Non-GAAP Financial Measures

This press release includes information about certain financial measures that are not prepared in accordance with U.S. generally accepted accounting principles (“GAAP” or “U.S. GAAP”), including adjusted EBITDA, adjusted net income, adjusted net income per diluted share and free cash flow. These non-GAAP measures have important limitations as analytical tools and should not be considered in isolation or as substitutes for an analysis of our results as reported under U.S. GAAP. Our use of these terms may vary from the use of similarly-titled measures by others in our industry due to the potential inconsistencies in the method of calculation and differences due to items subject to interpretation.

Management defines its non-GAAP financial measures as follows:

• Adjusted EBITDA represents GAAP income from operations adjusted to exclude, if applicable: (1) depreciation and amortization, (2) stock-based compensation expense, (3) asset impairment charges, and (4) other items affecting comparability during the period.

• Adjusted net income represents GAAP net income, adjusted for items that impact comparability for incremental or unusual costs incurred in the current period, which may include: (1) asset impairment charges, (2) executive separation and other severance charges, (3) non-recurring foreign taxes, interest and penalties and (4) costs related to exit activities.

• Adjusted net income per diluted share represents adjusted net income (as defined above), divided by the diluted weighted-average number of shares outstanding for the period.

• Free cash flow represents GAAP net cash provided by operations, less capital expenditures.

Management believes that these non-GAAP financial measures, when viewed with our results under U.S. GAAP and the accompanying reconciliations, provide useful information about our period-over-period growth and provide additional information that is useful for evaluating our operating performance. However, adjusted EBITDA, adjusted net income, adjusted net income per diluted share and free cash flow are not measures of financial performance under U.S. GAAP and, accordingly, should not be considered substitutes for or superior to net income and net income per diluted share and net cash provided by operating activities as indicators of operating performance.

A reconciliation of GAAP to Non-GAAP financial measures is included in this press release.
