Pro Forma Information (unaudited)

The following unaudited pro forma financial information is based on the historical financial statements of the Company and presents the Company’s results as if the acquisitions of EnvisionTEC, Adaptive 3D, Aerosint, Dental Arts Labs, A.I.D.R.O., Brewer Dental, May Dental, and ExOne had occurred on January 1, 2020 (in thousands):

​

The unaudited pro forma financial information was computed by combining the historical financial information of the Company and EnvisionTEC, Adaptive 3D, Aerosint, Dental Arts, A.I.D.R.O., Brewer Dental, May Dental, and ExOne along with the effects of the acquisition method of accounting for business combinations as though the companies were combined on January 1, 2020. The unaudited pro forma information does not reflect the potential benefits of cost and funding synergies, opportunities to earn additional revenues, or other factors, and therefore does not represent what the actual net revenues and net loss would have been had the companies been combined as of this date.
