On September 3, 2014, in connection with the Federal Trade Commission’s (the “FTC”) review of the pending acquisition of Trulia, Inc., a Delaware corporation (“Trulia”), by Zillow, Inc., a Washington corporation (“Zillow”), which will result in both Trulia and Zillow becoming wholly owned subsidiaries of Zebra Holdco, Inc. (“HoldCo”) (the “Merger”), Trulia received a request for additional information and documentary material (the “Second Request”) from the FTC. Issuance of the Second Request extends the waiting period under the Hart-Scott-Rodino Antitrust Improvements Act of 1976 until 30 days after Trulia and Zillow have substantially complied with the Second Request, unless the waiting period is extended voluntarily by the parties or terminated earlier by the FTC. Trulia and Zillow are gathering information to respond promptly to the Second Request and intend to cooperate with the FTC.

On September 3, 2014, Trulia and Zillow issued a joint press release announcing that they each had received a Second Request from the FTC. A copy of the joint press release is attached hereto as Exhibit 99.1.

The following exhibits are filed herewith:

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. Forward-looking statements generally relate to future events or our future financial or operating performance. 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 Merger and satisfaction of closing conditions precedent to the consummation of the proposed Merger, 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 that will be discussed in the Registration Statement on Form S-4 to be filed by HoldCo with the SEC at a future date. 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.
