Materialise Reports Second Quarter 2025 Results

LEUVEN, Belgium--(BUSINESS WIRE)—July 24, 2025 -- 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 second quarter ended June 30, 2025.

Highlights – Second Quarter 2025

· Total consolidated revenue decreased 5.8% to 64,831 kEUR compared to the corresponding 2024 period; however at the same time our Materialise Medical segment showed a further 16.7% growth.

· Gross profit as a percentage of revenue for the second quarter of 2025 increased to 58.3%, compared to 57.0% for the corresponding 2024 period.

· Adjusted EBIT improved to 3,058 kEUR for the second quarter of 2025 from 646 kEUR for the first quarter of 2025, although it remained below the 3,872 kEUR of the corresponding 2024 period.

· Net result for the second quarter remained positive at 199 kEUR, or 0.0 EUR per diluted share, despite a significant impact from unfavorable exchange rate fluctuations.

· Driven by positive free cash flow during the first half of 2025, our reported net cash position increased by 2,025 kEUR to 63,045 kEUR compared to December 31, 2024.

CEO Brigitte de Vet-Veithen commented, “Our Materialise Medical segment once again demonstrated its resilience, growing by almost 17% compared to the same period of 2024. At the same time increasing geo-political uncertainty and sustained macro-economic headwinds negatively impacted revenues in our Materialise Manufacturing and Materialise Software segments, and therefore also our consolidated revenue in the second quarter of 2025. Despite revenue pressure we were able to materially improve our operational profitability in Q2 2025 compared to prior periods through structural and targeted cost control. Unfavorable effects from exchange rate fluctuations significantly impacted our quarterly financials, but we nevertheless again reported a positive net result.”

Total revenue for the second quarter of 2025 decreased 5.8% to 64,831 kEUR from 68,797 kEUR for the second quarter of 2024. Adjusted EBIT was 3,058 kEUR for the second quarter of 2025 compared to 3,872 kEUR for the 2024 period.

Adjusted EBITDA for the second quarter of 2025 was 8,288 kEUR compared to 9,188 kEUR for the 2024 period.

Segment Adjusted EBITDA amounted to (807) kEUR compared to 2,416 kEUR for the same period in 2024, while the segment Adjusted EBITDA margin was (3.6)% compared to 8.2% for the second quarter of 2024.

Operating result amounted to 2,730 kEUR compared to 3,801 kEUR for the second quarter of 2024.

Net financial result was (3,052) kEUR compared to 1,033 kEUR for the second quarter of 2024, reflecting highly unfavorable effects from unrealized exchange rate fluctuations.

The second quarter of 2025 contained income tax benefits of 521 kEUR, compared to income tax expenses of (959) kEUR in the second quarter of 2024.

As a result of the above, net profit for the second quarter of 2025 was 199 kEUR, compared to 3,875 kEUR for the same period in 2024. Total comprehensive income for the second quarter of 2025, which includes exchange differences on translation of foreign operations, was 823 kEUR compared to 3,093 kEUR for the corresponding 2024 period.

Net shareholders’ equity at June 30, 2025 was 249,488 kEUR compared to 248,578 kEUR at December 31, 2024.

2025 Guidance

Mrs. de Vet-Veithen concluded, “As we move through 2025 we see a risk that geo-political volatility and macro-economic uncertainty intensify and also impact the business climate for the remainder of this year. Unfavorable foreign exchange fluctuations might also add to the pressure on our revenue line and reported net result. We therefore believe it is prudent to slightly reduce our revenue guidance for the full fiscal year to a range of 265,000 to 280,000 kEUR. We remain convinced though that the fundamentals of our business are solid and resilient and believe that further structural cost efficiencies will allow us to safeguard operational profitability. Despite the slightly lower revenue outlook we are therefore reconfirming our Adjusted EBIT guidance of 6,000 kEUR to 10,000 kEUR for fiscal year 2025 in line with our earlier communications in February and April of this year.”

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 to EBIT and EBITDA, respectively (i) share-based compensation expenses, (ii) acquisition or divestiture-related expenses of business combinations, (iii) impairments and revaluation of fair value due to business combinations and (iv) costs incurred in relation to corporate initiatives, restructurings or reorganizations that are of a non-recurring nature. 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.
