FOR IMMEDIATE RELEASE

The ExOne Company Reports Second Quarter 2021 Results

NORTH HUNTINGDON, PA, August 11, 2021 – The ExOne Company (Nasdaq: XONE) (“ExOne” or the “Company”), the global leader in industrial sand and metal 3D printers using binder jetting technology, today reported financial results for the second quarter ended June 30, 2021.

ExOne will not host a conference call to discuss its results for the second quarter of 2021 or provide forward guidance, due to the announced proposed acquisition of ExOne by Desktop Metal, Inc (“Desktop Metal”). Information relating to the proposed acquisition can be found at the Desktop Metal investor relations website – https://ir.desktopmetal.com.

“The ExOne Team is proud to deliver a record second quarter revenue result, driven by market momentum we continue to see for our portfolio of products, which we believe is the strongest in the company’s history and also in the binder jet marketplace, as well as an all-time high in both quarterly recurring revenue and backlog,” said John Hartner, ExOne’s CEO.

“We’re also benefiting from secular trends that we believe will continue to lift ExOne long into the future, such as a desire to lightweight cars and aircraft for sustainability benefits. While COVID-19 continues to cast uncertainty over the markets we serve, we also see early signs of an economic restart, led by the U.S. market, and a shift in manufacturing approach as a direct result of the pandemic that also benefits ExOne. We’re talking to an increasing number of manufacturers who are looking to de-risk and shorten supply chains in a way that supports increased interest in additive manufacturing technologies such as binder jetting for more localized production.”

Non-GAAP Financial Measure

This press release includes a non-GAAP financial measure that is not prepared in accordance with, nor as an alternative to, GAAP. In addition, this non-GAAP financial measure is not based on any standardized methodology prescribed by GAAP and is not necessarily comparable to a similarly titled measure presented by other companies.

The table captioned “Adjusted EBITDA Reconciliation” in this press release provides a reconciliation of net loss (the most directly comparable GAAP measure) to Adjusted EBITDA.

ExOne defines Adjusted EBITDA (earnings before interest, taxes, depreciation and amortization) as net income (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, gain from sale-leaseback of property and equipment and other expense – net. Use of Adjusted EBITDA, 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.
