FOR IMMEDIATE RELEASE

The ExOne Company Reports 2016 First Quarter Results

NORTH HUNTINGDON, PA, May 10, 2016 – The ExOne Company (NASDAQ: XONE) (“ExOne” or “the Company”), a global provider of three-dimensional (“3D”) printing machines and 3D printed and other products, materials and services to industrial customers, reported financial results today for the first quarter ended March 31, 2016.

S. Kent Rockwell, Chairman and Chief Executive Officer, commented, “We’re pleased with the growth realized in our first quarter of 2016, which represents record first quarter revenue for us. Our operating results also indicate the progress we’re making from a productivity standpoint as our global associates gain experience and continue to realize efficiencies.”

He added, “Our customers give us reason to be encouraged, as we shipped five machines and finished the quarter with solid backlog. We are also already seeing stronger order flow early in the second quarter and approach mid-year with cautious but increasing optimism about 2016.”

Consolidated sales for the 2016 first quarter were $8.4 million, up 24% compared with $6.8 million in the prior-year period. Machine revenue doubled to $2.2 million and non-machine revenue grew 9% to $6.2 million.

Given the long sales cycle and significance of a machine’s average selling price relative to total revenue, fluctuations in machine-sale revenue vary from quarter to quarter. ExOne does not believe that such quarter-to-quarter fluctuations are necessarily indicative of larger trends.

First Quarter Operations – Improved Efficiency is Evident

Gross profit was $1.9 million, resulting in a 22.3% gross margin, in the 2016 first quarter compared with breakeven in the 2015 first quarter. Compared with the prior year, first quarter 2016 gross margin demonstrated increased production efficiency, as the 2015 quarter was impacted by inefficiencies resulting from the Company’s transition into its new and expanded facilities as well as deployment of its ERP system.

Operating loss significantly improved to $5.3 million compared with a $7.9 million operating loss in the first quarter of 2015. SG&A expenses decreased to $5.3 million compared with $6.1 million in the prior-year quarter, due primarily to a reduction in consulting and professional fees. R&D expenses of $1.9 million for the quarter were up from $1.7 million in the 2015 first quarter. Net loss for the 2016 first quarter was $5.5 million, or a $0.35 loss per diluted share, compared with a net loss of $7.7 million, or a $0.53 loss per diluted share, for the prior-year period.

Adjusted earnings before interest, taxes, depreciation and amortization (“EBITDA”) was a $3.6 million loss in the 2016 first quarter, compared with a $6.2 million loss in last year’s first quarter. ExOne management believes that when used in conjunction with other measures prepared in accordance with accounting principles generally accepted in the United States (“GAAP”), that adjusted EBITDA, a non-GAAP measure, assists in the understanding of operating performance. See the attached tables for important disclosures regarding the Company’s use of adjusted EBITDA as well as a reconciliation of net loss to adjusted EBITDA for the quarters ended March 31, 2016 and 2015.

Capitalization – Infusion of Liquidity Reflects Insider Confidence

Cash and cash equivalents as of March 31, 2016 were $31.3 million, compared with $19.3 million at December 31, 2015. As previously announced in January 2016, the Company sold 1.4 million shares of its common stock to an entity controlled by S. Kent Rockwell, resulting in net proceeds to the Company of approximately $12.4 million. Cash outflows for operating and investing activities of $1.2 million in the 2016 first quarter demonstrate stabilization of cash usage compared with $5.9 million used in the first quarter of 2015.

Outlook – Growing Acceptance Balanced with Cost Management

Mr. Rockwell concluded, “We continue to have confidence in the headway we’re making in the global marketplace. Additionally, we have been working diligently to lower our breakeven point by critically looking at all of our costs and prudently making adjustments where possible. We believe that these efforts are making us a stronger and more effective organization that is focused on customer satisfaction.”

Adjusted EBITDA Reconciliation

(in millions)

(Unaudited)

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, 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 the rules of the U.S. Securities and Exchange Commission, is intended as a supplemental measure of ExOne’s performance that is not required by, or presented in accordance with, GAAP. Adjusted EBITDA should not be considered as an alternative to net loss or any other performance measure derived 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 Adjusted EBITDA is meaningful to its investors to enhance their understanding of ExOne’s financial performance. 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.
