Item 8.01. Other Events.

On September 3, 2014, Trulia, Inc. (“Trulia”) and Zillow, Inc. (“Zillow”) each announced that they had received a request for additional information and documentary material, commonly referred to as a “second request,” from the Federal Trade Commission (the “FTC”) in connection with Zillow’s pending acquisition of Trulia (the “Proposed Transaction”). The second requests extended the waiting period to consummate the Proposed Transaction under the Hart Scott-Rodino Antitrust Improvements Act of 1976 until the 30th day after substantial compliance by Trulia and Zillow with the second requests, unless terminated sooner by the FTC. On September 24, 2014, Zillow entered into an agreement (the “Timing Agreement”) with the FTC not to consummate the Proposed Transaction prior to 60 days after both Trulia and Zillow substantially comply with the second requests. The Timing Agreement does not prevent the parties from consummating the Proposed Transaction sooner if the FTC grants early termination, closes its investigation or accepts for public comment a proposed consent agreement settling the matter. Trulia and Zillow are preparing responses to the second requests and intend to comply with the second requests as promptly as possible. The parties anticipate that the Proposed Transaction will be completed in 2015.

Cautionary Note Regarding Forward-Looking Statements

This filing contains forward-looking statements within the meaning of Section 27A of the Securities Act of 1933 and Section 21E of the Securities Exchange Act of 1934, as amended, including statements related to the compliance by Trulia and Zillow with the second requests as promptly as possible and the anticipated timing of the completion of the Proposed Transaction. Forward-looking statements generally relate to future events. In some cases, you can identify forward-looking statements because they contain words such as “may,” “will,” “should,” “expects,” “plans,” “anticipates,” “could,” “intends,” “target,” “projects,” “contemplates,” “believes,” “estimates,” “predicts,” “potential” or “continue” or the negative of these words or other similar terms or expressions that concern Trulia’s expectations, strategy, plans or intentions. Trulia’s expectations and beliefs regarding these matters may not materialize, and actual results in future periods are subject to risks and uncertainties that could cause actual results to differ materially from those projected, including but not limited to: the ability of the parties to consummate the Proposed Transaction and satisfaction of closing conditions precedent to the consummation of the Proposed Transaction, including obtaining necessary regulatory approvals.

The forward-looking statements contained in this filing are also subject to other risks and uncertainties, including those more fully described in Trulia’s filings with the SEC, including its Annual Report on Form 10-K for the year ended December 31, 2013, which was filed with the SEC on March 3, 2014, as amended on May 23, 2014, and its Quarterly Report on 10-Q for the quarterly period ended June 30, 2014, and those under the caption “Risk Factors” in the Registration/Joint Proxy Statement (as defined below). The forward-looking statements in this filing are based on information available to Trulia as of the date hereof, and Trulia disclaims any obligation to update any forward-looking statements, except as required by law.
