ExOne Announces European Facility Expansion in Gersthofen, Germany

Construction of new facility to consolidate existing German operations, creating efficiency and providing platform for strategic growth

NORTH HUNTINGDON, PA, August 6, 2013 – The ExOne Company (NASDAQ: XONE) (“ExOne” or “the Company”), a global provider of three-dimensional (“3D”) printing machines and printed products to industrial customers, announced today that it has purchased land and will soon begin construction on a new facility in Gersthofen, Germany, in the district of Augsburg.

Upon completion, which is estimated to occur in the latter half of 2014, the facility will comprise approximately 150,700 square feet of production, warehouse, service and R&D space as well as approximately 27,600 square feet for offices. ExOne will be consolidating its five existing leased facilities in Augsburg which currently occupy an aggregate of approximately 77,500 square feet into its new facility, providing expansion capacity to support its global growth strategy.

Rainer Hoechsmann, General Manager of ExOne GmbH, commented, “We were fortunate to secure a strategic location for our new facility, located in an industrial region directly on a German autobahn. This provides easy access to our growing customer base, our vendors, as well as our employees. Consolidating all of our activities, which include production, warehousing, a production service center, an R&D lab, as well as our European headquarters, into a single facility will further improve our efficiency, enhancing our ability to service our customers.”

ExOne has engaged GOLDBECK Süd GmbH, a turnkey provider of construction services which focuses on Central Europe, Great Britain, Austria and Switzerland, for the design of its new facility, and expects to engage GOLDBECK for the construction of this facility.
