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:

As previously disclosed in a Current Report on Form 8-K filed with the Securities and Exchange Commission on March 8, 2016, Mr. Gregory Waldorf did not stand for re-election to the Zillow Group, Inc. (“Zillow Group”) Board of Directors at the expiration of his then-current term at the company’s 2016 Annual Meeting of Shareholders held on June 15, 2016 (the “2016 Annual Meeting”). Mr. Waldorf reported that his voluntary departure is not due to any disagreement with the company on any matter relating to the company’s operations, policies, or practices.

Nasdaq Stock Market Listing Rule 5605(b)(1) requires that a majority of the company’s Board of Directors be comprised of directors who satisfy the independence requirements of the Nasdaq Stock Market Listing Rules. As a result of Mr. Waldorf’s voluntary departure from the Board of Directors, a majority of the company’s Board of Directors is not comprised of directors who satisfy the independence requirements of the Nasdaq Stock Market Listing Rules. On June 15, 2016, Zillow Group notified Nasdaq of its non-compliance with Nasdaq Stock Market Listing Rule 5605(b)(1) and the company’s intent to reestablish a majority of independent directors before the expiration of the applicable cure period provided by the Nasdaq Stock Market Listing Rules, which will run until the earliest of Zillow Group’s 2017 Annual Meeting of Shareholders, the first anniversary of Mr. Waldorf’s departure from the Board of Directors, and December 12, 2016 if the company’s next annual meeting of shareholders is held before December 12, 2016. On June 17, 2016, the company received notice from Nasdaq confirming the non-compliance and cure period.

Mr. Waldorf served as a director of Trulia, Inc. from September 2005 until February 2015, at which time he was elected to the company’s Board of Directors. The Board expresses its sincere appreciation for Mr. Waldorf’s service to the company.

At the 2016 Annual Meeting, Zillow Group shareholders approved the amendment and restatement of the Zillow Group, Inc. Amended and Restated 2011 Incentive Plan (the “Amended and Restated Plan”) to increase the total number of shares authorized for issuance under the Amended and Restated Plan by 2,500,000 shares.

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 2016 Annual Meeting filed with the Securities and Exchange Commission on April 25, 2016, 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, on June 15, 2016, Zillow Group held its 2016 Annual Meeting. At the 2016 Annual Meeting, Zillow Group’s shareholders voted on the following matters with the following results:
