DEREGISTRATION OF SECURITIES

This Post-Effective Amendment (this “Post-Effective Amendment”) relates to the following Registration Statement on Form S-8 (the “Registration Statement”) of MINDBODY, Inc. (the “Registrant”):

On December 23, 2018, the Registrant entered into an Agreement and Plan of Merger (the “Merger Agreement”) with Torreys Parent, LLC, a Delaware limited liability company (“Parent”), and Torreys 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 Registrant (the “Merger”), with the Registrant surviving the Merger as a wholly owned subsidiary of Parent. Parent and Merger Sub were formed by affiliates of Vista Equity Partners Fund VI, L.P., a Cayman Islands exempted limited partnership (“Vista Fund VI”), and Vista Equity Partners Fund VII, L.P., a Cayman Islands exempted limited partnership (“Vista Fund VII”, and together with Vista Fund VI, the “Vista Funds”). On February 15, 2019, pursuant to the terms of the Merger Agreement, Parent acquired the Registrant through the Merger.

As a result of the Merger, the Registrant has terminated any and all offerings of securities pursuant to the Registration Statement. In accordance with the undertakings made by the Registrant in the Registration Statement to remove from registration by means of a post-effective amendment any of the securities that had been registered which remain unsold at the termination of the offering, the Registrant hereby removes from registration any securities of the Registrant registered but unsold under the Registration Statement as of the date hereof. The Registration Statement is hereby amended to reflect the deregistration of such securities.
