ExOne defines Adjusted EBITDA (earnings before interest, taxes, depreciation and amortization) as net loss (as calculated under accounting principles generally accepted in the United States (“GAAP”)) plus interest expense, provision (benefit) for income taxes, depreciation and amortization, equity-based compensation, and other income – net. Use of Adjusted EBITDA, which is a non-GAAP financial measure, as defined under SEC rules, is intended as a supplemental measure of ExOne’s performance that is not required by, or presented in accordance with, GAAP. The presentation of Adjusted EBITDA is not intended to be a substitute for, and should not be considered in isolation from, net loss reported in accordance with GAAP. The Company’s presentation of Adjusted EBITDA should not be construed to imply that its future results will be unaffected by unusual or non-recurring items.

The Company believes that Adjusted EBITDA is meaningful to its investors to enhance their understanding of ExOne’s financial results. Although Adjusted EBITDA is not necessarily a measure of the Company’s ability to fund its cash needs, the Company understands that it is frequently used by securities analysts, investors and other interested parties as a measure of financial performance and to compare ExOne’s performance with the performance of other companies that report Adjusted EBITDA. ExOne’s calculation of Adjusted EBITDA may not be comparable to similarly titled measures reported by other companies.
