2017 Guidance

Mr. Leys concluded, “We are adjusting our revenue and Adjusted EBITDA guidance for 2017 to reflect our acquisition of ACTech in the fourth quarter. For fiscal 2017, we now expect to report consolidated revenue between 140,000 – 143,000 kEUR and Adjusted EBITDA between 13,000 – 14,000 kEUR. Separately, based on year-to-date software sales, we are revising our outlook for deferred revenue from annual licenses and maintenance in 2017 and now expect an increase between 2,000 – 3,000 kEUR as compared to 2016.”

The company previously expected to report consolidated revenue between 128,000 - 134,000 kEUR and Adjusted EBITDA between 10,500 – 13,500 kEUR in 2017, with amounts closer to the high end of those ranges. The amount of deferred revenue generated in 2017 from annual licenses and maintenance was previously expected to increase by an amount between 4,000 - 5,000 kEUR as compared to 2016.

Non-IFRS Measures

Materialise uses EBITDA and Adjusted EBITDA as supplemental financial measures of its financial performance. EBITDA is calculated as net profit plus income taxes, financial expenses (less financial income), shares of loss in a joint venture and depreciation and amortization. Adjusted EBITDA is determined by adding non-cash stock-based compensation expenses and acquisition-related expenses of business combinations 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 profit, 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. The company's calculation of EBITDA and Adjusted EBITDA may not be comparable to similarly titled measures reported by other companies. EBITDA and Adjusted EBITDA should not be considered as alternatives to net profit or any other performance measure derived in accordance with IFRS. The company's presentation of EBITDA and Adjusted EBITDA should not be construed to imply that its future results will be unaffected by unusual or non-recurring items.
