Zillow now will be the exclusive provider of all real estate listings for HGTV's FrontDoor, giving agents and brokerages that list on Zillow substantial additional marketing for their listings.

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

For more information about potential factors that could affect Zillow's business and financial results, please review the "Risk Factors" described in Zillow's Quarterly Report on Form 10-Q for the three months ended June 30, 2012 and Zillow's Annual Report on Form 10-K for the year ended December 31, 2011 filed with the Securities and Exchange Commission, or SEC, and in Zillow's other filings with the SEC. Except as may be required by law, Zillow does not intend, and undertakes no duty, to update this information to reflect future events or circumstances.

Use of Non-GAAP Financial Measures

To provide investors with additional information regarding our financial results, this press release includes references to Adjusted EBITDA, which is a non-GAAP financial measure. We have provided a reconciliation of Adjusted EBITDA to net income, the most directly comparable GAAP financial measure, within this earnings release.

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:

• Adjusted EBITDA does not reflect our cash expenditures or future requirements for capital expenditures or contractual commitments;
• Adjusted EBITDA does not reflect changes in, or cash requirements for, our working capital needs;
• Adjusted EBITDA does not consider the potentially dilutive impact of share-based compensation;
• Although depreciation and amortization are non-cash charges, the assets being depreciated and amortized may have to be replaced in the future, and Adjusted EBITDA does not reflect cash capital expenditure requirements for such replacements or for new capital expenditure requirements;
• Adjusted EBITDA does not reflect certain facility exit charges; and
• Other companies, including companies in our own industry, may calculate Adjusted EBITDA differently than we do, limiting its usefulness as a comparative measure.

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