NORTH HUNTINGDON, Pa., March 27, 2013 (GLOBE NEWSWIRE) -- The ExOne Company (Nasdaq:XONE) ("ExOne" or "the Company"), a global provider of three-dimensional ("3D") printing machines and printed products to industrial customers, reported financial results today for its fourth quarter and full year 2012, which ended December 31, 2012.

Kent Rockwell, Chairman and Chief Executive Officer of ExOne commented, "We made solid progress in 2012. The recent technological advances of our 3D printing machines create persuasive economics for our industrial customers, who have demonstrated a growing interest in applying 3D printing in their manufacturing processes."

Revenue for the fourth quarter of 2012 was $12.7 million, up $10.0 million over 2011 fourth quarter. Net income of $0.9 million was improved over a net loss of $2.8 million for the same period in 2011. Included in the fourth quarter was a $1.5 million reduction in license fees.

For the full year of 2012 revenue was $28.7 million, up 87.6% from revenue of $15.3 million in 2011. Net loss in 2012 was $10.2 million, compared with a net loss of $8.0 million in 2011.

During the fourth quarter of 2012, machine sales were $8.9 million. Eight machines were sold in the 2012 fourth quarter and thirteen in the full year, whereas one machine was sold in the prior-year's fourth quarter and five machines were sold in 2011. Higher sales were the result of customer demand for the Company's new machine models. Additionally, there has been an increasing trend of acceptance of additive manufacturing among global industrial manufacturers. Machine sales represented 70% of total sales in the 2012 fourth quarter. 

PSC revenue for the 2012 fourth quarter was up 52%, or $1.3 million, over the prior-year period. PSC revenue in 2012 improved by 31.3%, or $3.1 million, as the Company has increased its customer base from growing demand for 3D printed parts.   

Higher Machine Sales Results in Margin Expansion for the Quarter

Gross profit was $6.2 million in the fourth quarter of 2012, improved $5.8 million from gross profit of $0.4 million in the fourth quarter of 2011 driven by the significant increase in machine sales. Gross profit as a percent of sales was 49.0% in the fourth quarter of 2012 compared with 14.6% in the same period of 2011. Gross profit included a $1.5 million reduction in license fees.

Operating income for the fourth quarter of 2012 was $2.0 million, or 16.0% of sales, compared with an operating loss of $2.1 million in the fourth quarter of 2011. Improved operating income was due to higher sales volume. 

Full Year 2012 Operational Review

Gross profit was $12.1 million, or 42.4% of sales, in 2012. SG&A expenses were $18.3 million, or 63.8% of sales, for the year compared with $7.3 million, or 47.7% of sales, in 2011. Increased SG&A reflected investments for growth which included additional personnel to support higher future sales volume. Also included in SG&A for the year was approximately $1.9 million of expenses associated with the preparation for the initial public offering ("IPO") and a $7.7 million stock compensation expense. R&D expenses were $1.9 million in 2012, compared with $1.5 million in 2011. 

Excluding the aforementioned expenses of $9.6 million, operating income would have been $1.5 million for 2012, up from an operating loss of $5.2 million during 2011. As reported, consolidated operating loss for the year was $8.1 million. Backlog at December 31, 2012 was $5.1 million.

Balance Sheet Bolstered by Successful IPO

On February 12, 2013, ExOne completed its IPO of 6,095,000 shares of common stock at $18 per share, resulting in net proceeds to the Company of $92.0 million. Approximately $10.3 million of the proceeds were used to repay outstanding debt. In addition, we purchased the assets and repaid the liabilities of our variable interest entities for approximately $7.0 million. The Company plans to use the remainder of the proceeds to fund ExOne's growth initiatives, including the build out of an additional ten PSCs over the next three to five years and the expansion of our global manufacturing capacity, as well as further research and development, process improvement initiatives and other corporate purposes.

Strong Growth Anticipated in 2013

Mr. Rockwell commented, "Our technology and experience has enabled us to develop 3D printing machines that provide an economic alternative to traditional industrial applications. Our unique solution for the industrial market puts us in a leading position as a 3D printer and manufacturer in the global economy. We believe we are a driver of the rate of adoption of 3D printing for industrial applications as well as a benefactor of the growing relevance of this technology in manufacturing. As we move forward, our priorities are to capture this opportunity by developing PSCs in high potential market areas and advancing our capabilities with new metal-based materials."

For 2013, the Company estimates that full year revenue will be in a range of about $48 million to $52 million with approximately two-thirds of revenue expected to fall in the latter half of the year. The Company plans to launch two additional PSCs during the second half of 2013 which will expand its operations to a total of seven. Gross margin for the year is expected to be approximately 42% to 46%. Operating expenses are expected to be in the range of $18 million to $21 million. 

Approximately $40 million to $50 million in growth capital expenditures are planned over the next two years which includes the expansion of the Company's global manufacturing capacity and PSC development.
