Item 1.01 Entry Into a Material Definitive Agreement.

On December 3, 2013, HomeAway, Inc. (the “Company”) and HomeAway Australia Holdings Pty Ltd (“HomeAway Australia”), a wholly-owned subsidiary of the Company, entered into a Share Sale Agreement (“Sale Agreement”) with Fairfax Media Limited (“Fairfax Media”) and Fairfax Digital Pty Limited (“Fairfax Digital”), a division of Fairfax Media, pursuant to which HomeAway Australia purchased all of the shares of Stayz Pty Limited (“Stayz”) on December 5, 2013 from Fairfax Digital for a purchase price of approximately $198 million in cash. As a result of the transactions under the Sale Agreement, Stayz became a wholly-owned subsidiary of HomeAway Australia on December 5, 2013.

The foregoing description of the Sale Agreement does not purport to be complete and is qualified in its entirety by reference to the Sale Agreement, which is filed as Exhibit 2.1 hereto and incorporated herein by reference.

The Sale Agreement has been included to provide investors and security holders with information regarding its terms. It contains representations and warranties of Fairfax Digital and HomeAway Australia made to and solely for the benefit of the other parties. These representations and warranties are qualified by information in confidential schedules and exhibits that the parties have exchanged in connection with the signing and closing of the Sale Agreement. Furthermore, certain warranties in the Sale Agreement were used for the purpose of allocating risk, rather than establishing matters as facts and may be subject to standards of materiality applicable to the contracting parties that differ from those applicable to investors and security holders. In addition, investors and security holders should not rely on the warranties as characterizations of the actual state of facts, since they were only made as of the date of the Sale Agreement and are modified in part by the underlying confidential schedules and exhibits. Moreover, information concerning the subject matter of the representations and warranties may change after the date of the Sale Agreement, which subsequent information may or may not be fully reflected in the Company’s public disclosures.

Item 2.01 Completion of Acquisition or Disposition of Assets.

On December 5, 2013, the Company consummated the purchase of all of the shares of Stayz pursuant to the Sale Agreement, as described in Item 1.01 of this Current Report on Form 8-K, which is incorporated herein by reference.

On December 4, 2013, the Company issued a press release in which it announced the acquisition of all of the shares of Stayz pursuant to the Sale Agreement. A copy of the press release is attached hereto as Exhibit 99.1.

Neither the information in Section 7.01 of this Current Report on Form 8-K nor the information in the press release shall be deemed “filed” for purposes of Section 18 of the Exchange Act, or incorporated by reference in any filing under the Securities Act of 1933, as amended, or the Exchange Act, except as shall be expressly set forth by specific reference in such a filing.
