LEUVEN, Belgium--(BUSINESS WIRE)—April 25, 2024 -- Materialise NV (NASDAQ:MTLS), a leading provider of additive manufacturing and medical software and of sophisticated 3D printing services, today announced its financial results for the first quarter ended March 31, 2024.

Highlights – First Quarter 2024

CEO Brigitte de Vet-Veithen commented, “In line with expectations our consolidated revenue decreased by 3% compared to the same period of 2023, an exceptionally strong quarter which showed 24% growth.

While continued investments in sustainable growth and the ongoing conversion to a recurring revenue business model impacted our operational profitability, we delivered a positive net result and an improved net cash position.”

We are also maintaining our Adjusted EBIT guidance of 11,000 kEUR to 14,000 kEUR for fiscal year 2024.”

Non-IFRS Measures

Materialise uses EBIT, EBITDA, Adjusted EBIT and Adjusted EBITDA as supplemental financial measures of its financial performance. EBIT is calculated as net profit plus income taxes, financial expenses (less financial income) and shares of profit or loss in a joint venture. EBITDA is calculated as net profit plus income taxes, financial expenses (less financial income), shares of profit or loss in a joint venture and depreciation and amortization. Adjusted EBIT and Adjusted EBITDA are determined by adding share-based compensation expenses, acquisition-related expenses of business combinations, impairments and revaluation of fair value due to business combinations to EBIT and EBITDA, respectively. Management believes these non-IFRS measures to be important measures as they exclude the effects of items which primarily reflect the impact of financing decisions and, in the case of EBITDA and Adjusted EBITDA, long term investment, rather than the performance of the company’s day-to-day operations. The company also uses segment Adjusted EBITDA to evaluate the performance of its three business segments. As compared to net profit, these measures are limited in that they do not reflect the cash requirements necessary to service interest or principal payments on the company’s indebtedness and, in the case of EBITDA and Adjusted EBITDA, these measures are further 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 changes associated with impairments. Management evaluates such items through other financial measures such as financial expenses, 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 EBIT, EBITDA, Adjusted EBIT and Adjusted EBITDA may not be comparable to similarly titled measures reported by other companies. EBIT, EBITDA, Adjusted EBIT 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 EBIT, EBITDA, Adjusted EBIT and Adjusted EBITDA should not be construed to imply that its future results will be unaffected by unusual or non-recurring items.
