“Assuming that inflation stabilizes in 2023, we expect our continued revenue growth to gradually result in a stronger Adjusted EBITDA, which we currently anticipate to total between 25,000 and 30,000 kEUR for 2023. We expect our three segments to contribute to our Adjusted EBITDA in line with their contributions to our revenue growth.

“At the same time, we want to note that the developments in Ukraine will likely have an important impact on the European and global economy as well as on the continuity of the important services we source from our brave workforce in Kyiv and could, therefore, also have a significant effect on our results for 2023. We will continue to monitor these developments, which remain unpredictable.”

Non-IFRS Measures

Materialise uses EBITDA and Adjusted EBITDA as supplemental financial measures of its financial performance. EBITDA is calculated as net profit(loss) plus income taxes, financial expenses (less financial income), shares of profit or loss in a joint venture and depreciation and amortization. Adjusted EBITDA is determined by adding share-based compensation expenses, acquisition-related expenses of business combinations, impairments and revaluation of fair value due to 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(loss), 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(loss) 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.
