About ExOne

ExOne is a global provider of 3D printing machines and 3D printed and
other products, materials and services to industrial customers. ExOne’s
business primarily consists of manufacturing and selling 3D printing

its installed base of 3D printing machines. ExOne’s machines serve

its network of ExOne Adoption Centers (“EACs”) and Production Service

including consumables and replacement parts, and other services,
including training and technical support that is necessary for
purchasers of its 3D printing machines to print products. The Company

box size and printing speed) uniquely position ExOne to serve the needs
of industrial customers.
