ACTech

On October 4, 2017, we acquired ACTech, a full-service manufacturer of complex metal parts. As described in more detail below, the acquired business has increased the scope of our Materialise Manufacturing segment’s operations and had a significant impact on our results of operations for the third quarter of 2018, resulting in increases to our revenues, operating expenses and net result.

Third Quarter 2018 Results

Total revenue for the third quarter of 2018 increased 44.6% (9.9% excluding ACTech) to 46,732 kEUR (35,494 kEUR excluding ACTech) compared to 32,307 kEUR for the third quarter of 2017.

Business Combinations – ACTech

Our audited financial statements for the year ended December 31, 2017 appearing in our Annual Report on Form20-F, as filed with the U.S. Securities and Exchange Commission on April 30, 2018, included a provisional accounting for the ACTech business combination. The fair value analysis with respect to the assets and liabilities acquired was not yet finalized as of the reporting date.

During September 2018, we completed the fair value analysis of the ACTech business combination, with corresponding adjustments to intangible assets, property, plant and equipment, inventories and contracts in progress, investment grants and deferred taxes. The impact has been accounted for as retrospective adjustments to our consolidated statement of financial position as of December 31, 2017 and our consolidated income statement for the year ended December 31, 2017. The total impact on the consolidated reserves for the year ended December 31, 2017 amounted to 461 kEUR.

The adjustments are summarized below.

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 addingnon-cash stock-based

- 3 -

compensation expenses and acquisition-related expenses of business combinations to EBITDA. Management believes thesenon-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’sday-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 ornon-recurring items.
