Item 2.01 Completion of Acquisition or Disposition of Assets.

On March 3, 2014, The ExOne Company, a Delaware corporation (the “Company”), through its wholly-owned subsidiary ExOne Americas LLC, a Delaware limited liability company (“ExOne Americas”), entered into an Asset Purchase Agreement by and among ExOne Americas, Machin-A-Mation Corporation, Metal Links, LLC and Mr. William R. Dega (the “Machin-A-Mation Asset Purchase Agreement”) to acquire (i) substantially all the assets of Machin-A-Mation Corporation (“Machin-A-Mation”), a specialty machine shop located in Chesterfield, Michigan, and (ii) the real property on which Machin-A-Mation’s business is located from Metal Links, LLC (“Metal Links”), a Michigan limited liability company, for an aggregate purchase price of approximately $5.0 million (the “Machin-A-Mation Acquisition”). The closing took place simultaneously upon execution of the Machin-A-Mation Asset Purchase Agreement on March 3, 2014. Machin-A-Mation’s business will remain in its current Chesterfield, Michigan location, complementing the Company’s nearby production service center (“PSC”) in Troy, Michigan, where the Company focuses on advanced 3D printed cores and molds for the aerospace and shipbuilding industries.

On March 6, 2014, ExOne GmbH, a wholly-owned subsidiary of the Company acquired all of the shares of MWT - Gesellschaft für Industrielle Mikrowellentechnik mbH (“MWT”), a pioneer in industrial-grade microwaves based in Elz, Germany, for approximately $4.8 million pursuant to the terms of a Purchase and Assignment Contract between Reinhard Schulze and ExOne GmbH (the “MWT Share Purchase Agreement”). The closing took place simultaneously upon execution of the agreement on March 6, 2014. MWT’s microwave operation will be operationally integrated with the Company’s Augsburg, Germany manufacturing operations.

To fund the Machin-A-Mation and the MWT Acquisitions, the Company used a portion of the net proceeds from its secondary offering of common stock that was completed on September 13, 2013.
