Mr. Leys concluded, “The additive manufacturing market continues to evolve, with new applications steadily finding their way to
market. We intend to continue positioning Materialise to benefit from these promising growth opportunities in the coming years. In
2020, we will dedicate significant attention to supporting the development of a wide variety of meaningful end part applications with
our generic software tools, and, more specifically, to growing a select number of key applications Materialise is more directly involved
in.

In our Materialise Software segment, we intend to maintain our leadership position in the existing service bureau market and to
grow our position in the expanding end part manufacturing market through both innovation and strategic partnerships.In our
Materialise Medical segment, we intend to continue penetrating the hospital market with our software tools and simultaneously driving
the next stage of innovation in the orthopaedic, CMF and cardiovascular markets.

In our Materialise Manufacturing segment, we will increasingly focus on complex and unique parts, in general, and on the growth of our wearables and aviation initiatives, in particular.

“For fiscal 2020, which has started with some unexpected challenges for businesses worldwide in connection with the COVID-19 virus,
we expect to report consolidated revenue between 202,000 kEUR – 215,000 kEUR, with growth coming primarily from our Materialise
Software and Materialise Medical segments, and Adjusted EBITDA between 27,500 kEUR – 30,000 kEUR. We expect the amount of
deferred revenue we generate from annual licenses and maintenance in 2020 to increase by an amount between 3,000 kEUR – 5,000
kEUR.”

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.
