Differences in Zillow Group’s actual results from those described in these forward-looking statements may result from actions taken by Zillow Group as well as from risks and uncertainties beyond Zillow Group’s control. Factors that may contribute to such differences include, but are not limited to, Zillow Group’s ability to successfully integrate and realize the benefits of our past or future strategic acquisitions or investments; Zillow Group’s ability to maintain and effectively manage an adequate rate of growth; Zillow Group’s ability to maintain or establish relationships with listings and data providers; the impact of the real estate industry on Zillow Group’s business; Zillow Group’s ability to innovate and provide products and services that are attractive to its users and advertisers; Zillow Group’s ability to increase awareness of the Zillow Group brands; Zillow Group’s ability to attract consumers to Zillow Group’s mobile applications and websites; Zillow Group’s ability to compete successfully against existing or future competitors; the reliable performance of Zillow Group’s network infrastructure and content delivery processes; and Zillow Group’s ability to protect its intellectual property.

Use of Non-GAAP Financial Measures

To provide investors with additional information regarding our financial results, this press release includes references to certain pro forma financial results, Adjusted EBITDA and non-GAAP net income (loss) per share, all of which are non-GAAP financial measures. We have provided a reconciliation of pro forma Adjusted EBITDA to pro forma net income (loss), Adjusted EBITDA to net income (loss), the most directly comparable GAAP financial measure, and a reconciliation of net income (loss), adjusted, to net income (loss), as reported on a GAAP basis, and the calculations of non-GAAP net income (loss) per share — basic and diluted and pro forma weighted-average shares outstanding — basic and diluted, within this earnings release.

The pro forma financial results included in this press release, although helpful in illustrating the financial characteristics of Zillow Group under one set of assumptions, are not true historical financial results. They are provided for informational purposes and do not attempt to represent Zillow Group’s actual financial condition if the February 2015 acquisition of Trulia had been completed on the applicable dates of the financial statements presented herein, or to predict or suggest future results.

Adjusted EBITDA is a key metric used by our management and board of directors to measure operating performance and trends, and to prepare and approve our annual budget. In particular, the exclusion of certain expenses in calculating Adjusted EBITDA facilitates operating performance comparisons on a period-to-period basis.

Our use of Adjusted EBITDA has limitations as an analytical tool, and you should not consider it in isolation or as a substitute for analysis of our results as reported under GAAP. Some of these limitations are:

Because of these limitations, you should consider Adjusted EBITDA alongside other financial performance measures, including various cash flow metrics, net income (loss) and our other GAAP results.

Our presentation of non-GAAP net income (loss) per share excludes the impact of share-based compensation expense, acquisition-related costs, restructuring costs, income taxes and the loss (gain) on divestiture of businesses. This measure is not a key metric used by our management and board of directors to measure operating performance or otherwise manage the business. However, we provide non-GAAP net income (loss) per share as supplemental information to investors, as we believe the exclusion of share-based compensation expense, acquisition-related costs, restructuring costs, income taxes and the loss (gain) on divestiture of businesses facilitates investors’ operating performance comparisons on a period-to-period basis. You should not consider these metrics in isolation or as substitutes for analysis of our results as reported under GAAP.
