DEREGISTRATION OF SECURITIES

This Post-Effective Amendment relates to the following registration statements of Marketo, Inc. (the “Company”), each pertaining to the registration of the shares offered under certain employee benefit and equity plans and agreements, originally filed on Form S-8 and as amended from time-to-time (collectively, the “Registration Statements”):

On May 27, 2016, 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 a wholly owned subsidiary of Parent (“Merger Sub”). Pursuant to the Merger Agreement, on August 16, 2016, Merger Sub merged with and into the Company, and the Company continued as the surviving corporation and as a wholly owned subsidiary of Parent (the “Merger”).

As a result of the Merger, the Company has terminated all offerings of its securities pursuant to its existing registration statements, including the Registration Statements. Accordingly, the Company is filing this Post-Effective Amendment to the Registration Statements pursuant to Rule 478 under the Securities Act of 1933, as amended, to hereby terminate the effectiveness of the Registration Statements, and in accordance with the undertakings made by the Company in the Registration Statements to remove from registration, by means of this Post-Effective Amendment, any of the securities that had been registered but remain unsold at the termination of the offering, the Company hereby removes from registration all such securities, if any. Each Registration Statement is hereby amended, as appropriate, to reflect the deregistration of all such securities.
