ITEM 8.01 Other Events.

As previously announced, on May 27, 2016, Marketo, Inc., a Delaware corporation (“Marketo” or the “Company”), entered into an Agreement and Plan of Merger (the “Merger Agreement”) with Milestone Holdco, LLC, a Delaware limited liability company (“Parent”), and Milestone Merger Sub, Inc., a Delaware corporation and wholly owned subsidiary of Parent (“Merger Sub”), providing for the merger of Merger Sub with and into the Company (the “Merger”), with the Company surviving the Merger as a wholly owned subsidiary of Parent. The consummation of the Merger is conditioned upon, among other things, the expiration or termination of any waiting periods applicable to the consummation of the Merger under the Hart-Scott-Rodino Antitrust Improvements Act of 1976 (the “HSR Act”). On June 22, 2016, the U.S. Federal Trade Commission notified Marketo that early termination of the waiting period under the HSR Act was granted, effective immediately.

The consummation of the Merger remains subject to approval by Marketo’s stockholders and the satisfaction or waiver of customary closing conditions set forth in the Merger Agreement.
