Materialise Reports Third Quarter 2014 Results

Leuven, Belgium – November 12, 2014 - Materialise NV (NASDAQ: MTLS), a leading provider of additive manufacturing software and of sophisticated 3D printing services, today announced its financial results for the third quarter ending September 30, 2014.

Highlights – Third Quarter 2014

• Revenue increased 16.9% year over year to 19,833 kEUR

• 3D Printing software sales increased 29%

• Total software sales were 31% of total revenue

• R&D increased by 1,145 KEUR to 18.5% of total revenue

• Adjusted EBITDA, excluding non-cash stock based compensation expenses, was 2,055 kEUR for a 10.4% margin.

“Our second quarter as a public company was another very active and successful period for Materialise,” said Executive Chairman Peter Leys. “We delivered revenue growth of 17% while continuing to invest heavily in developing new products and expanding our sales reach. Consistent with the second quarter, we continued to drive growth of our 3D printing software. The capital we raised through our IPO has given us the flexibility to make buy or build decisions about the most efficient way to accelerate our growth, and our recent acquisition of OrthoView Holdings Limited, the world’s leading provider of 2D digital pre-operative planning and templating solutions for orthopedic surgeons, is an important step in expanding our distribution channels. In summary, we are executing well on both the company’s near- and our longer-term strategic objectives.”

Third Quarter 2014 Results

Total revenues for the third quarter of 2014 increased by 16.9% to 19,833 kEUR compared to 16,973 kEUR for the third quarter of 2013, driven by strong gains in the software and industrial production segments. Adjusted EBITDA, excluding stock-based compensation expenses, decreased from 2,460 kEUR to 2,055 kEUR reflecting ongoing investments in both research and development and sales and marketing. The adjusted EBITDA margin in the third quarter was 10.4% compared to 14.5% last year.

Revenues from the 3D Printing Software segment, which offers proprietary software worldwide through programs that enable and enhance the functionality of 3D printers and 3D printing operations, increased by 29.0 % to 4,438 kEUR for the third quarter of 2014 from 3,441 kEUR for the same quarter last year. Growth was fueled by a significant increase in new license sales across all regions, showing an accelerated growth in revenue generated with OEMs. EBITDA increased from 1,345 kEUR to 1,518 kEUR while the EBITDA margin declined to 34.2% from 39.1% last year due significant investments in S&M and R&D expenses, which collectively increased 46% year-over-year, in line with our announced strategy.

Revenues from the Medical segment, which offers both a medical software platform and a portfolio of medical devices and clinical engineering services to our customers, increased by 3.8% to 7,090 kEUR for the third quarter of 2014 compared to 6,833 kEUR for the same quarter last year. Near-term growth was constrained by the conversion from perpetual to annual licenses and the maturation of the knee guide business. Sales of medical software decreased 2% to 1,748 kEUR from 1,791 kEUR due to the license conversion, as evidenced by the fact that the share of annual licenses increased to 29% of new license sales from 7% last year. Revenues from the direct sale of guides and implants increased by 53% from the previous year. EBITDA decreased from 1,213 kEUR to 677 kEUR and the EBITDA margin fell to 9.5% from 17.8% due to significant investments in R&D projects (up 50% versus Q3 of last year) including the investments in metal printing and X-ray guide technology, among others, which are directly impacting profitability.

Revenues from the Industrial Production segment, which primarily offers 3D printing services to industrial and commercial customers, increased 22.1% to 8,190 kEUR for the third quarter of 2014 from 6,708 kEUR for last year’s third quarter. Growth in the quarter was largely driven by higher sales of the company’s early-stage growth businesses (i.materialise and RapidFit), which collectively increased their revenue by 84%. Sales of end parts rose 37% in the 2014 third quarter from the prior-year period. EBITDA rose to 753 kEUR from 600 kEUR and the EBITDA margin improved to 9.2% from 8.9% for last year’s quarter. Excluding the growth businesses, the Q3 2014 EBITDA margin was 18.8% versus 16.3% the prior year.

Gross profit was 12,154 kEUR for the third quarter of 2014 compared to 10,691 kEUR for the 2013 quarter. The gross profit margin decreased to 61.3% for the third quarter of 2014 from 63.0% for the prior-year period. This decrease was largely due to the relatively high increase in revenue provided by RapidFit and i.materialise and some of our complex surgery product lines (Mobelife and OBL), which do not yet provide corresponding contributions to our margins.

Selling and marketing expenses were 6,382 kEUR for the third quarter of 2014 compared to 5,417 kEUR for the third quarter of 2013. This 965 kEUR increase resulted from additional investments, mainly in the 3D printing software and industrial production segments.

Research and development expenses increased by 45% to 3,672 kEUR for the third quarter of 2014 from 2,527 kEUR for the prior-year period, reflecting continued heavy investment with a number of active projects in various stages of development, including metal printing and X-ray. All of the company’s research and development spending is expensed and none is capitalized.

Other operating income increased by 271 kEUR to 1,464 kEUR from 1,193 kEUR for the prior-year period. For the three months ended September 30, 2014, 915 kEUR out of the 1,464 kEUR consisted of withholding tax exemptions for qualifying researchers and partial funding of R&D projects, as compared to 810 kEUR for the three months ended September 30, 2013. Financial income for the third quarter of 2014 rose to 2,396 kEUR from 40 kEUR in the prior-year quarter due to a foreign exchange gain on the portion of IPO proceeds kept in USD.

Net profit for the third quarter of 2014 was 2,559 kEUR, versus 1,380 kEUR for the prior-year period, an increase of 1,179 kEUR or 85%. Total comprehensive income for the third quarter of 2014, which reflects exchange differences on translation of foreign operations, was 2,830 kEUR, an increase of 1,471 kEUR versus the prior-year period.

At September 30, 2014, the Company had cash and equivalents of 75,044 kEUR, an increase of 62,446 kEUR since December 31, 2013, largely due to cash received from the company’s initial public offering. Cash flow from operations in the third quarter of 2014 was 28 kEUR.

Net shareholder’s equity at September 30, 2014 was 85,284 kEUR, an increase of 67,549 kEUR since December 31, 2013.

2014 Guidance

For fiscal 2014, management expects to report consolidated revenue between 79,000 kEUR and 81,000 kEUR. Management intends to continue investing aggressively invest in research and development and sales and marketing initiatives. Depending on the pace of investments, management expects consolidated Adjusted EBITDA for fiscal 2014 to be between 5,000 kEUR and 6,000 kEUR.

Non IFRS Measures

Materialise uses EBITDA and Adjusted EBITDA as supplemental financial measures of its operational performance. EBITDA is calculated as net income before finance costs, income taxes and depreciation and amortization. Adjusted EBITDA is determined by adding stock-based compensation expense and one-time IPO related expenses to EBITDA. Management believes these non-IFRS measures to be important measures as they exclude the effects of items which primarily reflect the impact of long-term investment and financing decisions, rather than the performance of the company’s day-to-day operations. As compared to net income, these measures are limited in that they do not reflect the periodic costs of certain capitalized tangible and intangible assets used in generating revenues in the company’s business, or the charges associated with impairments. Management evaluates such items through other financial measures such as capital expenditures and cash flow provided by operating activities. The company believes that these measurements are useful to measure a company’s ability to grow or as a valuation measurement.
