Check the appropriate box below if the Form 8-K filing is intended to simultaneously satisfy the filing obligation of the registrant under any of the following provisions:

On February 17, 2015, pursuant to the Agreement and Plan of Merger, dated as of July 28, 2014 (the “Merger Agreement”) by and among Zillow, Inc. (“Zillow”), Trulia, Inc. (“Trulia”), and Zillow Group, Inc. (f/k/a Zebra Holdco, Inc., “Zillow Group”), following the completion of the mergers contemplated by the Merger Agreement (the “Trulia transaction”), each of Zillow and Trulia became wholly owned subsidiaries of Zillow Group.

In connection with the completion of the Trulia transaction on February 17, 2015 (the “Effective Date”), Zillow Group assumed the Zillow, Inc. Amended and Restated 2011 Incentive Plan, as amended (the “Existing Plan”). All equity awards that were outstanding under the Existing Plan as of the Effective Date were assumed by Zillow Group and converted into awards under the Existing Plan for an equal number of shares of Class A common stock of Zillow Group on otherwise the same terms and conditions (including the vesting schedule and the exercise price as applicable) that applied to such awards immediately prior to the Effective Date.

On June 11, 2015, Zillow Group held its 2015 Annual Meeting of Shareholders (the “2015 Annual Meeting”), at which its shareholders approved the amendment and restatement of the Zillow Group, Inc. Amended and Restated 2011 Incentive Plan (the “Amended and Restated Plan”) to (i) increase the total number of shares authorized for issuance under the Amended and Restated Plan by 1,500,000 shares from 3,800,000 shares to 5,300,000 shares, (ii) provide the flexibility to offer Class C capital stock under the Amended and Restated Plan, in addition to, or in lieu of Class A common stock, in the event Zillow Group lists Class C capital stock on a national securities exchange, and (iii) update references from “Zillow, Inc.” to “Zillow Group, Inc.” as applicable, to reflect the completion of the Trulia transaction.

The Compensation Committee of the Zillow Group Board of Directors (the “Compensation Committee”) will continue to administer the Amended and Restated Plan. Under the Amended and Restated Plan, employees, officers, directors, consultants, agents, advisors and independent contractors are eligible to receive awards. Awards granted under the Amended and Restated Plan may consist of stock options, stock appreciation rights, stock awards, restricted stock, stock units, performance shares, performance units, cash-based awards or other incentives payable in cash or in shares of Zillow Group stock as may be determined by the Compensation Committee.

The foregoing summary of the Amended and Restated Plan, and summaries of the Amended and Restated Plan set forth in Zillow Group’s definitive proxy statement for the 2015 Annual Meeting filed with the Securities and Exchange Commission on April 27, 2015, are qualified in their entirety by reference to the full text of the Amended and Restated Plan, which is filed as Exhibit 10.1 to this Current Report.

As described above in Item 5.02, on June 11, 2015, Zillow Group held its 2015 Annual Meeting. At the 2015 Annual Meeting, Zillow Group’s shareholders voted on the following matters with the following results:

Consistent with the Board’s recommendation in Zillow Group’s 2015 Proxy Statement and the voting results, Zillow Group has determined to hold an advisory vote on the compensation of Zillow Group’s named executive officers every third year.
