We are exposed to market risk from fluctuations in interest rates and foreign currency exchange rates which may adversely affect our results of operations and financial condition. We seek to minimize these risks through regular operating and financing activities. Interest Rate Risk Although we mainly have loans outstanding with a fixed interest rate, some of the loans have been contracted with variable interest rates. The most significant loans with variable interest rates have been secured by means of a variable to fixed interest rate swap. We therefore believe that we are not materially affected by changes in interest rates. For information with respect to the interest rate swaps, see Note 20 to our audited consolidated financial statements. Foreign Exchange Rate Risk We transact business globally and are subject to risks associated with fluctuating foreign exchange rates. The geographic areas outside of the Eurozone to which we sell our products and services are generally not considered to be subject to a substantially higher inflation than in the Eurozone. In the years ended December 31, 2025, 2024 and 2023, 32%, 36%, and 34% of our revenue, respectively, were derived from sales in a currency different from the euro. Receivables denominated in a foreign currency are initially recorded at the exchange rate at the transaction date and subsequently re-measured in euro based on period-end exchange rates. Transaction gains and losses that arise from exchange rate fluctuations are charged to income. We primarily have exposure to the U.S. dollar, British pound, Japanese yen and Brazilian real as foreign currency. If the U.S. dollar (rate for €1) would have appreciated by 10%, the operating result would have been € 0.5 million higher, excluding the effect of the cash and term accounts held in U.S. dollars. If the U.S. dollar (rate for €1) would have depreciated by 10%, the net result would have been € 0.4 million lower, excluding the effect of the cash and term accounts held in U.S. dollars. To limit the exposure to foreign currency rate fluctuations on the U.S. dollar and the PLN, we have entered into currency rate swaps. As of December 31, 2025, we had hedge agreements in place for $8.1 million and PLN 2.0 million, all maturing before year-end 2026. Refer to note 20 to our consolidated financial statements for the related fair value of these derivatives. Additionally, we are exposed to inflation risk, credit risk, liquidity risk and challenges related to capital management. Inflation Risk We transact business globally and are subject to risks associated with fluctuating inflation. The risk exists that, if inflation increases our costs of remuneration, materials, services, energy, and capital expenditures, we may not be able to offset such costs fully by increasing our selling prices. As such, in a high inflationary environment, our results of operations and financial condition may be adversely affected. 98 Table of Contents Credit Risk Credit risk is the risk that third parties may not meet their contractual obligations resulting in a loss for us. We are exposed to credit risk from our operating activities and from our financing activities, which are mainly deposits with financial institutions. We limit this exposure by contracting with credit-worthy business partners or with financial institutions which meet high credit rating requirements. In addition, the portfolio of receivables is monitored on a continuous basis. Customer credit risk is managed by each business unit subject to our established policy, procedures and controls relating to customer credit risk management. An impairment analysis is performed at each reporting date using a provision matrix to measure ECLs. The provision rates are based on days past due for groupings of various customer segments with similar loss patterns (i.e., by legal entity). The calculation reflects the probability-weighted outcome, the time value of money and reasonable and supportable information that is available at the reporting date about past events, current conditions and forecasts of future economic conditions. Generally, trade receivables are written-off if past due for more than one year and are not subject to enforcement activity. The maximum exposure to credit risk at the reporting date is the carrying value of each class of financial assets at amortized cost or fair value, as disclosed in Note 20 to our consolidated financial statements. We do not hold collateral as security. We evaluate the concentration of risk with respect to trade receivables as low, as our customers are located in several jurisdictions and industries and operate in largely independent markets. Liquidity Risk The liquidity risk is that we may not have sufficient cash to meet our payment obligations. This risk is countered by day-by-day liquidity management at corporate level. We have historically entered into financing and lease agreements with financial institutions to finance significant projects and certain working capital requirements. At December 31, 2025, we had cash and cash equivalents of € 133.9 million, while € 10.3 million of our € 63.1 million gross debt was short term. At December 31, 2025, we had an undrawn amount of € 15 million under our line of credit of € 50 million, as more fully described in Note 15 to our consolidated financial statements. Capital Management The primary objective of our capital management strategy is to ensure we maintain healthy capital ratios to support our business and maximize shareholder value. Capital is defined as our shareholders’ equity. We consistently review our capital structure and make adjustments in light of changing economic conditions. We made no changes to our capital management objectives, policies or processes during the years ended December 31, 2025, 2024 and 2023. On November 20, 2025 the Group successfully completed an additional listing of its ordinary shares on Euronext Brussels to complement the existing Nasdaq listing of its American depositary shares (ADSs) representing ordinary shares. A listing on Euronext Brussels may give the company access to additional capital in the future if needed, and is intended to create additional liquidity options for shareholders of the Company. In addition, a listing on Euronext Brussels provides the Group with enhanced operational flexibility, including the option to initiate ADS and/or share buyback programs. No shares were offered and no capital was raised in connection with the Euronext Brussels listing. On November 14, 2025 the Company’s general shareholder’s meeting adopted a resolution authorizing the Board of Directors to effectively initiate an ADS and/or share buy back program for a total amount of up to € 30.0 million. Repurchases were expected to be initiated by no later than January 2026 and executed within 12 months following initiation. The Company’s current intention is to hold any ADSs acquired (or underlying shares) in treasury. The Company may in the future use these as a consideration for mergers and acquisitions, and/or otherwise dispose of those ADSs or shares, including for potential share delivery commitments under future equity incentive plans. By December 31, 2025 a mandate had been signed with an independent US financial intermediary to execute ADS repurchases on Nasdaq for a total amount of up to the USD equivalent of € 30.0 million, but no actual transactions had taken place yet. For information regarding repurchase activity under the share buy back program subsequent to December 31, 2025, see Note 27 to the audited consolidated financial statements. 99 Table of Contents

A. [Reserved] B. Capitalization and Indebtedness Not applicable. C. Reasons for the Offer and Use of Proceeds Not applicable. D. Risk Factors Summary of Principal Risk Factors Risks Relating to our Business and Strategy ● The growth of the additive manufacturing market is uncertain, and we may not be able to maintain or increase the market share or reputation of our software, other products, services and technologies necessary to remain or become a market standard. ● The transition toward cloud-based software subscription models may not be successfully developed or implemented. ● We are dependent upon sales to the industrial and medical industries, and particularly in the automotive/aerospace and orthopedic/cranio-maxillofacial segments within such industries, and to certain customers in those industries. ● We rely on collaborations and strategic arrangements to develop products and services and expand into new markets, which entails risks, including the ability to enter into, maintain or effectively control relationships or realize their anticipated benefits. ● We operate in highly competitive market segments with rapidly decreasing barriers to entry. ● Our artificial intelligence and machine learning initiatives may not achieve their intended outcomes. ● We could experience unforeseen difficulties in building and operating key portions of our 3D printing infrastructure. 3 Table of Contents Risks Relating to our operations ● We may experience disruptions to our information technology systems, including security breaches in our products and computer systems, our customers’ networks, or our third party providers’ hosting services, and failures of service from third party technology, platform, carriers, server and hardware providers or our local servers. Related to this, we face specific risks around the privacy and security of personal data we collect, and our insurance coverage may prove insufficient to address resulting liabilities. ● Our international operations expose us to a variety of global and local economic, social, political and operational risks, and our failure to manage these risks could adversely affect our results of operations. Inflation, changes in tax laws or treaties, and broader macroeconmic conditions (such as the armed conflict in Ukraine) have had and may continue to have an adverse effect on our results. ● If our relationships with suppliers, including with limited source suppliers of raw materials, services consumables and other components, were to terminate or our manufacturing and services arrangements were to be disrupted, our business could be adversely affected. ● Our inability to retain and motivate key qualified personnel could negatively impact operations. ● Errors or defects in our software or other products could cause us to incur additional costs, lose revenue and business opportunities, reputational damage and potential liability, while our insurance policies may not provide adequate coverage for such liabilities. ● Our operations are subject to environmental laws and other government regulations and emerging sustainability risks, including environmental, social and governance (ESG) matters and disruptions to our 3D printing service center operations, which could have a material adverse effect on our business, financial condition and results of operations. Risks relating to our Materialise Medical Segment and Regulatory Environment ● Our medical business, financial condition, results of operations and cash flows are subject to substantial government regulations and healthcare policy changes, including reimbursement levels and price regulation, which could adversely affect us. ● The use, including the misuse or off-label use, of our medical services and products may be deemed unauthorized use or improper promotion, which could harm our image in the marketplace or result in injuries that lead to product liability suits, regulatory sanctions, or, where our products cause or contribute to a death, serious injury, or malfunction, obligations under medical device reporting regulations that could trigger voluntary corrective actions or agency enforcement. In addition, if our marketed medical devices are defective or pose safety risks, relevant governmental authoritis could require their recall, or we may initiate a voluntary recall. ● Alternative medical solutions could outperform the solutions we offer, rendering our solutions obsolete. ● Our Materialise Medical segment’s 3D printing operations are required to operate within a quality management system that is compliant with the regulations of various jurisdictions, including the requirements of ISO 13485, and the US Quality System Regulation, which is costly and could subject us to enforcement action. Risks relating to our Intellectual Property ● Our inability to obtain and maintain patent protection, or otherwise protect our intellectual property rights, could harm our business, while enforcing or acquiring such rights – or defending against third-party claims through litigation or other proceedings – may result in substantial costs, loss of key rights, or restrictions on the conduct of our business. ● Certain technologies and patents have been developed with collaboration partners and we may face restrictions on this jointly developed intellectual property. 4 Table of Contents Risks Related to our ordinary shares and ADSs ● Our ordinary shares and ADSs may experience price and volume fluctuations and future sales of substantial amounts of ordinary shares or ADS on either or both of the stock exchanges on which they are listed, or the perception that such sales could occur, could adversely affect the market value of the securities or the interests of shareholders. ● Members of our board of directors and senior management own a significant percentage of our ordinary shares, have signficant voting power and are able to exert significant influence over matters subject to shareholder approval. Further, holders of ADSs are not treated as shareholders of our company, and therefore do not have any rights as shareholders of our company, other than the rights they have pursuant to the deposit agreement. Holders of ADSs may have limited voting rights, may not receive distributions or any value for them if impractical or illegal to distribute, have limited rights to call shareholder meetings or submit proposals, and are also subject to certain transfer limitations. ● The dilutive effect of our warrants could have an adverse effect on the future market price of our ordinary shares or the ADSs or otherwise adversely affect the interests of our shareholders. ● We have no present intention to pay cash dividends on our ordinary shares in the foreseeable future and, consequently, investors’ only opportunity to achieve a return on their investment during that time is if the price of our ordinary shares or the ADSs appreciates. ● As a foreign private issuer dual-listed on Euronext Brussels and Nasdaq, we are exempt from certain U.S. securities laws and Nasdaq corporate governance rules, file less information with the SEC than U.S. domestic issuers, and may lose our foreign private issuer status in the future, resulting in significant additional costs. Further, investors outside Belgium may face difficulties serving process or enforcing foreign judgments against us, our directors, and senior management. ● If we fail to maintain an effective system of internal control over financial reporting in the future, we may not be able to accurately report our financial condition, results of operations or cash flows, which may adversely affect investor confidence in us. ● Operating as a dual-listed company has resulted in, and will continue to result in, significant increased costs, substantial management time devoted to compliance, and may require additional qualified accounting and financial personnel. ● We are a Belgian limited liability company listed in the U.S. and in Belgium, and shareholders of our company may have different and more limited shareholder rights than shareholders of a listed company in Belgium or of a U.S. listed corporation. ● Investors may not be able to participate in equity offerings and ADS holders may not receive any value for rights that we may grant. ● Shareholders in jurisdictions with currencies other than the euro face additional currency exchange risk, and fluctuations in the exchange rate between the euro and the U.S. dollar may increase the risk of holding our securities. ● Fluctuations in the exchange rate between the euro and the U.S. dollar may increase the risk of holding our ADSs and ordinary shares. ● We do not expect to be classified as a PFIC for U.S. federal income tax purposes, but there is a risk of such classification in the future, which could result in materially adverse U.S. federal income tax consequences to U.S. investors in our ordinary shares or ADSs. ● Changes in our U.S. federal income tax classification, or that of our subsidiaries, could result in adverse tax consequences to our 10% or greater U.S. shareholders. 5 Table of Contents Risks Relating to Our Business and Strategy The speed of the growth of the additive manufacturing market cannot be accurately predicted, and in a growing market, we may not be able to maintain or increase the market share or reputation of our software, other products, services and technologies necessary to remain or become a market standard The industrial and medical industries are generally dominated by conventional production methods with limited use of additive manufacturing, or 3D printing, technology in certain specific instances. If additive manufacturing technology for the production of end use parts does not gain more mainstream market acceptance, the pace by which additive manufacturing technology gains market acceptance does not accelerate or if the marketplace adopts additive manufacturing based on a technology other than the technologies that we currently use or serve (including in the medical, eyewear, footwear, fixtures and aerospace markets that we target), we may not be able to meet our growth objectives or increase or sustain the level of sales of our additive manufacturing software solutions, products and services, and our results of operations would be adversely affected as a result. In addition, the growth of the additive manufacturing industry is on a global scale and is subject to constant innovation and technological change. A variety of technologies compete against one another in our market, which is driven, in part, by technological advances and end-user requirements and preferences, as well as by the emergence of new standards and practices. As the additive manufacturing market evolves, the industry standards that are adopted and adhered to are a function of the inherent qualities of the technology as well as the willingness of members of the industry to adopt them. To remain competitive, we depend in large part on our ability to increase and maintain market share and influence in the industry in order to be recognized as a market standard. Nonetheless, in the future, our influence in setting standards for the additive manufacturing industry may be limited and the standards adopted by the market may not be compatible with our present or future products and services. In particular, our present or future software, other products and services and technologies could be rendered obsolete or uneconomical by technological advances by one or more of our present or future competitors, by other technologies or by new customer needs. Our ability to remain competitive will depend, in large part, on our ability to enhance and adapt our current software, other products and services and technologies to developments in technologies and to new and changing customer needs. We believe that to remain competitive we must continuously enhance and expand the functionality and features of our software, other products and services and technologies, which if not successfully done, could hinder our ability to achieve growth targets and maintain market competitiveness. There is no assurance that we will be able to maintain and enhance the market share of our current software, other products and services and technologies or respond to technological advances and emerging industry standards and practices on a cost-effective and timely basis. The dominant software subscription model in the industrial sector is changing, and we may not be successful in developing and deploying a cloud-based platform to offer our software. We offer 95% of our current software products through on-premises licensing (either on a perpetual or annual basis). We believe the industrial software market is evolving to Software as a Service, or SaaS, and other cloud-based models of software deployment where software providers typically license their applications to customers for use as a service on demand through web browser technologies. While we are deploying an increasing number of cloud-enabled platform components, through our CO-AM and Mimics Flow platforms to offer our software products either by means of a SaaS or a cloud-based subscription model, there is no guarantee that these platforms will be adopted by customers over other platforms and our results of operations could be adversely affected as a result. Even if we would successfully and timely complete this integration, which we aim to do by 2030, SaaS or cloud-based software offering may differ significantly from the perpetual and annual licensing models that we offered until recently. An increase in the prevalence of SaaS and cloud-based delivery models offered by us or our competitors could unfavorably impact the pricing of our on-premises software offerings and have a dampening impact on overall demand for our on-premises software product offerings, which could reduce our revenues and profitability. In addition, to the extent that demand for our SaaS or cloud-based offerings increases in the future, we may experience volatility in our reported revenues and operating results due to the differences in timing of revenue recognition between our perpetual and annual software licenses and our SaaS and cloud-based offering arrangements. 6 Table of Contents We are dependent upon sales to the industrial and medical industries, and particularly in the automotive/aerospace and orthopedic/cranio-maxillofacial segments within such industries, and to certain customers in those industries. Our revenue from products is currently relatively concentrated in the industrial and medical industries, and particularly in the automotive/aerospace and orthopedic/cranio-maxillofacial segments within such industries, respectively. Our sales to the orthopedic and the automotive industries account for 40% of the consolidated annual turnover. We furthermore expect additional growth to come from certain other specific markets, such as the cardiac and pulmonary markets. To the extent any of these industries experience, or continue to experience, a downturn, our results of operations may be adversely affected. We rely on collaborations, in-licensing arrangements, joint ventures, strategic alliances and partnerships to develop products and services and expand into new markets, but we may not be able to enter into or maintain such relationships or may not be in a position to exercise decision-making authority in such relationships, and the anticipated benefits of such transactions or arrangements may not be realized. In the ordinary course of our business, we enter into collaborations, in-licensing arrangements, joint ventures, strategic alliances or partnerships to develop proposed products or services and to pursue new markets. Proposing, negotiating and implementing collaborations, in-licensing arrangements, joint ventures, strategic alliances or partnerships may be a lengthy and complex process. Other companies, including those with substantially greater financial, marketing, sales, technology or other business resources, may compete with us for these opportunities or arrangements. We may not succeed in maintaining, renewing or extending existing collaborations or in identifying, securing, or completing any such new transactions or arrangements in a timely manner, on a cost-effective basis, on acceptable terms or at all. We may also not realize the anticipated benefits of any such transaction or arrangement. In particular, these collaborations may not result in the development of products or services that achieve commercial success or result in significant revenue and could be terminated prior to developing any products or services. In particular, our strategy includes entering into collaborations with our customers in certain large-scale markets and leveraging these collaborations to enter into other underserved specialty markets. In the medical market, we have entered into collaborations with DePuy Synthes Companies of Johnson & Johnson, or DePuy Synthes, and Zimmer Biomet Holdings, Inc., or Zimmer Biomet, as well as with Encore Medical, L.P. (d/b/a Enovis), or Enovis, Limacorporate Spa, or Lima, Mathys AG, or Mathys (which is now part of the same company as Enovis), Smith & Nephew Inc., or Smith & Nephew, Corin Ltd, or Corin, Medtronic Inc., or Medtronic, and Abbott Laboratories Inc., or Abbott, the expiration dates of which (unless renewed in accordance with our past practice) vary between March 2026 and September 2027. Increased adoption of our software, products and services, especially in potentially high-growth specialty markets, will depend in part on our current and future collaborators’ willingness to continue to adopt our additive manufacturing and other solutions in their markets and on our ability to continue to collaborate with these and other players. Certain of our customers that have initially relied on our 3D printing software and services have announced their intention to bring their 3D printing operations in-house and enter the market themselves, and other customers may also do so in the future as they gain experience and as 3D printing technology gains strategic importance, thus denying us continued access to their distribution channels (see also “We operate in market segments that are characterized by vigorous competition, and barriers to enter the software, medical and industrial markets with additive manufacturing solutions are decreasing rapidly.”). In addition, a change of control or other form of reorganization or restructuring of any of our collaboration partners, of which many operate in industries which are experiencing consolidation, deconsolidation or reorganization, may negatively impact our relationship, including as a result of (early) termination, non-renewal or renewal at less commercially favorable terms of our existing contractual arrangements. If we are not able to maintain or renew our existing collaborations at commercially favorable terms or at all and develop new collaborative relationships, our foothold in larger markets and expansion into potentially high-growth specialty markets could be harmed significantly and our results of operations may be adversely affected. 7 Table of Contents Additionally, we may not be in a position to exercise sole decision-making authority regarding the transaction or arrangement, which could create the potential risk of creating impasses on decisions, and our collaboration partners may have economic or business interests or goals that are, or that may become, inconsistent with our economic or business interests or goals. It is possible that conflicts may arise with our current or future collaboration partners, such as conflicts concerning the achievement of performance milestones, or the interpretation of terms under any agreement, such as those related to financial obligations, the ownership or license rights or control of intellectual- property developed before or during the collaboration or indemnification. If any conflicts arise with our current or future collaboration partners, they may act in their self-interest, which may be adverse to our best interest, and they may breach their obligations to us. In addition, we have limited control over the amount and timing of resources that our current collaboration partners or any future collaboration partners devote to our collaboration partners’ or our future products or services. Disputes with our collaboration partners may result in litigation or arbitration that would increase our expenses and divert the attention of our management. Further, these transactions and arrangements are contractual in nature and may be terminated or dissolved under the terms of the applicable agreements and, in such event, we may not continue to have rights to the products or access to the markets relating to such transaction or arrangement or may need to purchase such rights at a premium. The research and development programs that we are currently engaged in, or that we may establish in the future, may not be successful and our significant investments in these programs may be lost. To remain competitive, we invest, and intend to continue to invest, significant amounts in various research and development programs. There is no assurance, however, that these research and development programs will enable us to improve our existing 3D printing software solutions, products and services or create new software, products or services that address the needs of prospective end-users (including the increased use of additive manufacturing for personalized solutions and end use parts instead of prototypes and the trend of offering more cloud-enabled software solutions). Even if some of these programs are successful, it is possible that the new software, products or services developed from such programs will not be commercially viable, that new 3D printing technologies that we, or others, develop will eventually supplant our current 3D printing technologies, that changes in the manufacturing or use of 3D printers will adversely affect the need or demand for our software, products or services or that our competitors will create or successfully market 3D printing technologies that will replace our solutions, products and services in the market. As a result, any of our software solutions, products or services may be rendered obsolete or uneconomical and our significant investments in all or some of our research and development programs may be lost. We operate in market segments that are characterized by vigorous competition, and barriers to enter the software, medical and industrial markets with additive manufacturing solutions are decreasing rapidly. The market segments in which we operate, Materialise Software, Materialise Medical and Materialise Manufacturing, are characterized by vigorous competition, by the entry of competitors with innovative technologies, by consolidation of companies with complementary products, services and technologies, and by entry of large corporations in any one or more of our market segments, including certain of our former or current customers. In addition, the barriers to enter the software, medical and industrial markets with 3D printing solutions are decreasing rapidly. In the Materialise Software segment, the availability of computing devices with continually expanding performance at progressively lower prices contributes to the ease of market entry. Additionally, there are certain open-source software applications that are being offered free of charge or for a nominal fee that may place additional competitive pressure on us. 3D printer manufacturers, which closely work with their customers, may also successfully bundle their own software solutions with their equipment, which may make our independent software solutions obsolete. In addition, companies that have greater financial, technical, sales and marketing and other resources, including market leaders with significant in-house capacities in software development, or existing computer-aided design (CAD) or computer-aided manufacturing (CAM), or manufacturing execution system, or MES, software providers, are entering the additive manufacturing market and may very rapidly gain a significant share of the markets that we target (including through the acquisition of startup and scale-up companies that are active in the development and sale of additive manufacturing software tools). In the Materialise Medical segment, medical device companies are investing in 3D printing solutions that may compete with our software solutions, products and services. Companies that initially rely on us to enter the additive manufacturing market for medical applications may, as they gain experience and as 3D printing technology gains strategic importance, decide to develop their own in-house solutions and enter the market themselves with their own software, products or services, thus becoming competitors and denying us continued access to their distribution channels. In addition, startup and scale-up companies, as well as companies that have greater financial, technical, sales and marketing and other resources, are entering the additive manufacturing market and may very rapidly gain a significant share of the markets that we target. 8 Table of Contents In the Materialise Manufacturing segment, as additive manufacturing gains importance as a strategic technology, our customers are likely to bring 3D manufacturing in-house and reduce or even discontinue using our 3D printing services, resulting in a decreased prototyping demand. In addition, competitors with more efficient or profitable business models, superior techniques or more advanced technologies may take market share away from us, while our transition towards series manufacturing is still in a build-up phase. Also, in certain specific markets that our Materialise Manufacturing segment targets, including, among others, the shoe wear and eyewear markets, in which the adoption of 3D printing is slower than expected, established players may develop their own competitive solutions or may engage in collaborations with our competitors, preventing us from gaining a viable position in these markets. Because of these and other factors, competitive conditions in the industry are likely to intensify in the future. Increased competition could result in price reductions, reduced revenue and operating margins and loss of market share, any of which would likely harm our results of operations. We may not be successful in our artificial intelligence and machine learning initiatives, which could adversely affect our business, reputation or financial results. We have been developing and incorporating artificial intelligence (or AI) and machine learning (or ML) into our programs and platforms, particularly in the Materialise Medical segment. For example, we have implemented AI and ML algorithms to automate the preparation of patient specific cases related to segmentation tasks (such as selecting the anatomy out of stacks of CT or MRI images) and landmarking tasks (such as locating anatomical points in the CT or MRI scans). As with many innovations, AI and ML present risks, challenges and unintended consequences that could impact our successful ability to incorporate the use of AI and ML in our business. For example, our algorithms may be flawed and not achieve sufficient levels of accuracy or contain biased information, or our internal validation and quality control measures may prove to be deficient. In addition, our competitors or other third parties may incorporate AI and ML solutions into their platforms more successfully than us, and their AI and ML solutions may achieve higher market acceptance than ours, which may result in us failing to recoup our investments in developing ML and AI-powered offerings. We have made and expects to continue to make significant investments in our AI and ML technology. Our ability to employ AI and ML, or any ability of our competitors to do so more successfully, may negatively impact our business, impair our ability to compete effectively, result in reputational harm and have an adverse impact on our operating results. Moreover, our use of (generative) AI and ML may give rise to litigation risk, including potential intellectual-property or privacy liability. Because AI is an emerging technology, there is not a mature body of case law construing the appropriateness of certain of our uses of data – whether through the employment of large language models or other models leveraging data found on the internet – and the evolution of this law may limit our ability to exploit artificial intelligence tools, or expose us to litigation. Further, (generative) AI and ML presents emerging ethical issues and if our use of (generative) AI and ML algorithms draws controversy due to their perceived or actual impact on society, we may experience brand or reputational harm, competitive harm or legal liability. In addition, given the complex nature of (generative) AI and ML technology, we face an evolving regulatory landscape and significant competition from other companies, some of which have longer operating histories and significantly greater financial, technical, marketing, distribution, professional services, or other resources than ourselves. For example, the European Union’s Artificial Intelligence Act (or the AI Act) – the world’s first comprehensive AI law – has entered into force in 2024 and, with some exceptions, becomes effective in 2026. This legislation imposes significant obligations on providers and deployers of high risk AI systems, and encourages providers and deployers of AI systems to account for EU ethical principles in their development and use of these systems. If we develop or use (generative) AI or ML systems that are governed by the AI Act, it may necessitate ensuring higher standards of data quality, transparency, and human oversight, as well as adhering to specific and potentially burdensome and costly ethical, accountability, and administrative requirements. Any of the foregoing could adversely affect our business, reputation, or financial results. If businesses do not continue to adopt our platform for any of the reasons discussed above or for other reasons not contemplated, our sales would not grow as quickly as anticipated, or at all, and our business, operating results, and financial condition would be adversely affected. 9 Table of Contents We could experience unforeseen difficulties in building and operating key portions of our 3D printing infrastructure. We have designed and built our own 3D printing operations, some of the 3D printer platforms in use and other key portions of our technical infrastructure through which we serve our products and services, and we plan to continue to expand the size of our infrastructure through expanding our 3D printing facilities. The infrastructure expansion we may undertake may be complex, and unanticipated delays in the completion of these projects or availability of components may lead to increased project costs, operational inefficiencies, or interruptions in the delivery or degradation of the quality of our products. In addition, there may be issues related to this infrastructure that are not identified during the design and implementation phases, which may only become evident after we have started to fully utilize the underlying equipment, that could further degrade the user experience or increase our costs. Risks relating to our operations We may experience disruptions to our information technology systems, including security breaches in our products and computer systems, our customers’ networks, or our third party providers’ hosting services (particularly with the transition to SaaS and cloud-based applications), and failures of service from third party technology, platform, carriers, server and hardware providers or our local servers We make significant efforts to maintain the security and integrity of our product source code and computer systems. The risk of a security breach or disruption, particularly through cyber-attack or cyber intrusion, including by computer hackers, foreign governments and cyber terrorists, has increased as the number, intensity and sophistication of attempted attacks and intrusions from around the world have increased. These threats include identity theft, unauthorized access, DNS attacks, wireless network attacks, viruses and worms, advanced persistent threat, application centric attacks, peer-to-peer attacks, phishing, backdoor trojans and distributed denial of service attacks. Despite significant efforts to create and continuously reinforce the security barriers to such programs (by implementation of the ISO 27001 standards and enhanced cybersecurity protocols), it is virtually impossible for us to entirely eliminate this risk. Like all software products and computer systems, our software products and computer systems are potentially vulnerable to such cyber-attacks, and our computer systems have been subject to certain cyber security incidents in the past. Moreover, as we continue to invest in new lines of software and other products and services, we are exposed to increased security risks and the potential for unauthorized access to, or improper use of, the information of our product and service users. In addition, we are in an ongoing transition from distributing desktop software applications to developing and distributing online software services through our SaaS and cloud-based software applications. This transition comes with a shift in cybersecurity responsibilities from the customer to us, since we manage data we receive from our customers and may be responsible to our customers for breaches of their data. This shift in responsibilities requires us to implement appropriate internal changes and to invest in additional cybersecurity capabilities (including training, tooling, and processes). However, cybersecurity incidents and malicious internet-based activity continue to increase generally, and providers of cloud-based services have frequently been targeted by such attacks. We may be unable to anticipate or prevent techniques used to obtain unauthorized access or to sabotage systems because they change frequently and often are not detected until after an incident has occurred. In addition, the SaaS and cloud-based software applications business is a highly dynamic market with rapidly evolving regulatory requirements, and we need to continually improve our cybersecurity controls to ensure continued compliance. We are investing in information security and privacy certifications to meet these evolving requirements. However, given the rapidly evolving nature of the regulatory landscape (e.g., the Cybersecurity Maturity Model Certification program of the US Department of Defense, the EU-wide NIS2 directive, the upcoming EU-wide Cyber Resilience Act, and, where applicable, the EU Data Act), we may be unable to ensure timely compliance with these requirements, which may adversely impact our business, financial condition and results of operations. Furthermore, as we use third party cloud, technology, platform, carriers, server and hardware providers as well as local servers to host a major part of our servers as well as to host our SaaS and cloud-based software applications, the risk of a security breach or disruption is not limited to our products and computer systems but also applies to our providers’ hosting services as well as our customers’ networks. Moreover, breaches of our customers’ data caused by errors, omissions or hostile acts of third parties within the third party hosted environment are beyond our control, yet we would remain responsible for such data security incidents from a regulatory standpoint, in some instances. We may also be limited in our remedies against our third party hosting providers in the event of a failure of service. A failure or limitation of service or available capacity by our third party hosting providers could adversely affect our business and reputation. 10 Table of Contents In addition to security breaches, our systems may be vulnerable to damage and interruption from power loss, including as a result of natural disasters, computer system and network failures, loss of telecommunication services, operator negligence, loss of data and other disruptive events. There may also be disruptions during the configuration, implementation or operation of, or during the migration to, new, SaaS and cloud-based systems as part of our transition to such online software services. Finally, there could also be failures of service by third party technology, platform, carriers, server and hardware providers. If these providers are unable to handle current or higher volumes of use, experience any interruption in operations or cease operations for any reason or if we are unable to agree on satisfactory terms for a continued hosting relationship, we would be forced to enter into a relationship with other service providers or assume these hosting responsibilities ourselves. In addition to using third party providers, we have also established local servers and infrastructure in multiple offices, including in Leuven, which may also be subject to failure. We rely on our information technology systems and databases to manage numerous aspects of our business and to provide analytical information to management. Its information technology systems allow us to, among other things, optimize our software development and research and development efforts, organize our in-house 3D printing services logistics, efficiently purchase products from our suppliers, provide other procurement and logistic services, ship and invoice products to our customers on a timely basis, maintain cost-effective operations and generally provide service to our customers. Our information technology systems are an essential component of our business and growth strategies, and a disruption to or perceived failure in our information technology systems could significantly limit our ability to manage and operate our business efficiently. Any such disruption could therefore adversely affect our reputation, brand and financial condition. A security breach, disruptions or failure, whether of our products and servers, of our customers’ network security and systems or of third-party service providers, could disrupt the proper functioning of our software and other products and computer systems, disrupt access to our customers’ stored information and could lead to the loss of, damage to or public disclosure of our customers’ stored information, cause errors in the output of our or our customers’ work, allow unauthorized access to our sensitive, proprietary or confidential information, our customers or the patients that we and our customers serve through our medical solutions. Many jurisdictions have enacted laws mandating companies to inform individuals, shareholders, regulatory authorities, and others of security breaches. In addition, certain of our customer agreements may require us to promptly report security breaches involving their data on our systems or those of subcontractors processing such data on our behalf. This mandatory disclosure may be costly, harm our reputation, erode customer trust, and require significant resources to mitigate issues stemming from actual or perceived security breaches. If any of the foregoing occur, our reputation could be harmed, we could incur significant costs associated with remediation and the implementation of additional security measures or remediation, we may incur significant liability and financial loss, and we may be subject to regulatory scrutiny, investigations, proceedings, and penalties. In addition, certain of our customers are large and highly regulated, and if any of them were to conclude that our systems and procedures are insufficiently rigorous, they could terminate their relationships with us. As a result, our financial condition, results of operations and business could be adversely affected. As noted above, any security compromise that causes an apparent privacy violation could also result in legal claims or proceedings, liability under various laws and regulations that regulate the privacy, security, or breach of personal information, and related regulatory penalties. Our international operations expose us to a variety of global and local economic, social, political and operational risks, and our failure to manage these risks could adversely affect our results of operations We operate in various global markets outside of Belgium, with: ● subsidiaries in Malaysia, Japan, South Korea, Australia, China, Austria, the Czech Republic, France, Germany, Ukraine, the Netherlands, Poland, Italy, the United Kingdom, the United States and Colombia. ● property, plants and equipment in Belgium, several states in the United States, the United Kingdom, France, Japan, the Czech Republic, Malaysia, Ukraine, China, Colombia, Poland, Australia, Germany, India, Brazil, South Korea and Spain; and ● employees and consultants in Belgium, other European countries, Africa, the United States, other American countries and Asia Pacific. 11 Table of Contents During the financial year ended December 31, 2025 we generated only 2.3% of our revenue in Belgium. As a result, we are exposed to a range of global and local economic, social, health, environmental, political, regulatory and operational conditions, including, among other things, global health crises, recessions, currency fluctuations, high interest rates, inflation, labor shortages, civil unrest, political instability, tariffs, export controls, trade restrictions, and changing regulations, which could affect our strategy and operations and have a material adverse effect on our business, financial condition, results of operations and prospects. We face significant operational risks as a result of doing business internationally. These operational risks include operating in various legal systems which may contain conflicting regulatory requirements and which may be underdeveloped and subject to political interference, operating in countries with a higher incidence of corruption and fraudulent business practices, complex taxation issues and adverse tax consequences and liabilities, longer sales and payment cycles, transportation delays, difficulties in collecting accounts receivable, challenges in providing solutions across a significant distance, in different languages and among different cultures, difficulties in staffing and managing foreign operations, costs and difficulties of customizing products for foreign countries, seasonal reductions in business activity in certain parts of the world, particularly during the summer months in Europe and regulatory or contractual limitations on our ability to provide our services or sell or develop our products in certain foreign markets. Our international operations furthermore increase our exposure to macroeconomic events. Current macroeconomic events that adversely affect us include geopolitical instability resulting from the armed conflicts in Ukraine and the ongoing geopolitical tensions between the United States and China. Such regulatory and policy changes, including in relation to taxation, tariffs or trade, may significantly affect our business by increasing the cost of doing business, affecting our ability to sell our software, products and services and negatively impacting our profitability. In particular, there is currently significant uncertainty about the future relationship between the United States and various other countries, with respect to trade policies, treaties, government regulations, and tariffs. For example, the recent imposition of tariffs and/or changes in tariffs on various products by the United States and other countries, including the European Union and China, have introduced greater uncertainty with respect to trade policies and government regulations affecting trade between the United States and other countries, and new and/or increased tariffs may in the future subject us to additional costs and expenditure of resources. Major developments in trade relations, including the imposition of new or increased tariffs by the United States and/or other countries, and any emerging nationalist trends in specific countries could alter the trade environment and consumer purchasing behavior which, in turn, could have a material effect on our financial condition and results of operations. We cannot predict future trade policy and regulations in the United States and other countries, the terms of any renegotiated trade agreements or treaties, or tariffs and their impact on our business. An escalated trade war could have a significant adverse effect on world trade and the world economy. To the extent that trade tariffs and other restrictions imposed by the United States or other countries increase the price of, or limit the amount of, our products or components or materials used in our products imported into the United States or other countries, or create adverse tax consequences, the sales, cost, or gross margin of our products may be adversely affected and the demand from our customers for products and services may be diminished. Uncertainty surrounding international trade policy and regulations as well as disputes and protectionist measures could also have an adverse effect on consumer confidence and spending. If we deem it necessary to alter all or a portion of our activities or operations in response to such policies, agreements, or tariffs, our capital and operating costs may increase. Any similar or other economic, social, or political developments in the future could also adversely impact our business. Unfavorable conditions may depress sales in a given market and may result in actions that adversely affect our margins, constrain our operating flexibility or result in charges that are unusual or non-recurring. Inflation has had and may continue to have an adverse effect on our results. Inflationary pressures negatively impacted our operating margins and net income in fiscal 2023, 2024 and 2025, including increasing the costs of labor, energy, materials, and freight. We implemented price increases on many of our products and services in 2023, 2024 and 2025, in an effort to mitigate the effects of higher costs related to inflation. However, not all cost increases could be entirely offset, in part due to the delayed effect of price increases in multi-year agreements to which we are a party, where price increases may only be implemented at the renewal date. In addition, in Belgium, the salaries of our employees are indexed to inflation increases by law and, as a result, it may be difficult to keep our sales prices aligned with increases in our labor costs. If these inflationary pressures continue, our revenue, gross and operating margins and net income may be impacted in fiscal 2026 as well, which would harm our results of operations. 12 Table of Contents If our relationships with suppliers, including with limited source suppliers of raw materials, service consumables and other components, were to terminate or our manufacturing and service arrangements were to be disrupted, our business could be adversely affected. We purchase raw materials, service consumables and other components that are used in our production from third party suppliers. We currently use only a limited number of suppliers for several of the raw materials and services that we use for our printing and production activities. Our reliance on a limited number of vendors involves a number of risks, including: potential shortages of some key raw materials and critical service consumables or other components, for which there may be no appropriate substitute; printed material performance or quality shortfalls, if traceable to particular raw materials, consumables or other components, since the supplier of the faulty consumable or component cannot readily be replaced; discontinuation of a raw material, service consumable or other component on which we rely; potential insolvency of these vendors; and reduced control over delivery schedules, manufacturing capabilities, quality and costs. Alternative vendors may be unavailable, may be unwilling to supply, may not have the necessary regulatory approvals, or may not have in place an adequate quality management system or certification in line with our certifications. Furthermore, modifications to raw materials, service consumables or other components made by a, or due to change in, third party supplier could require new approvals from the relevant regulatory authorities before the modified raw materials, service consumables or other components may be used. If certain suppliers were to decide to discontinue production, or the supply to us, of a raw material, service consumable or other component that we use, the unanticipated change in the availability of supplies, or unanticipated supply limitations, could cause delays in, or loss of, sales, increased production or related costs and, consequently, reduced margins, and damage to our reputation. In addition, because we use a limited number of suppliers, and there is an increasing trend of consolidation among our existing suppliers, the increase in the prices charged by our suppliers may have an adverse effect on our results of operations, as we may be unable to find a supplier who may supply it at a lower price. As a result, the loss of a limited source supplier could adversely affect our relationships with our customers and our results of operations and financial condition. We depend on the knowledge and skills of key personnel throughout our entire organization, and if we are unable to retain and motivate them or recruit additional qualified personnel, our operations could suffer. Our success depends upon the continued service and performance of key personnel at all levels within our organization, including machine operators, engineers, designers, software developers, salespeople, product managers and senior management. These key personnel members include persons who have been providing services to us for over 25 or 30 years, persons who have assisted us with the establishment and development of entire business units and persons who have such extensive knowledge of us and our operations that we consider them to have a critical role for us. Our success also depends on our ability to identify, hire, develop, motivate and retain qualified personnel in the future. Competition for key employees in our industry is intense and we cannot guarantee that we will be able to retain our personnel or attract new, qualified personnel. We may need to invest significant amounts of cash and equity to attract and retain new employees and we may not realize returns on these investments. The loss of the services of key personnel could prevent or delay the implementation and completion of our strategic objectives, could divert management’s attention to seeking certain qualified replacements or could adversely affect our ability to manage our company effectively. Each member of our personnel may resign at any time. Only some of the members of our personnel are subject to non-competition agreements, which may also be difficult to enforce. Accordingly, the adverse effect resulting from the loss of certain members of our key personnel could be compounded by our inability to prevent them from competing with us. We do not carry key-man insurance on any member of our senior management team or other key personnel. If we lose the ability to hire and retain key executives and employees with a diversity and high level of skills in appropriate domains (such as research and development and sales), it could have a material adverse impact on our business activities and results of operations. In addition, the success of our acquisitions may depend in part on our ability to retain senior management and other key personnel of acquired companies following their acquisition and to continue to attract such persons to us. For example, the companies we acquire may depend on small teams of founders and senior managers with extensive market knowledge and relationships or that exercise substantial influence over the acquired business. As a result, the loss of such persons could adversely affect us. 13 Table of Contents As a result of the armed conflict in Ukraine, our supporting operations in Kyiv are expected to continue to be subject to continuous reorganization, uncertainty and instability. We have an office in Kyiv, Ukraine where more than 400 of our collaborators are mainly engaged in engineering, software development and IT support, as well as other staff functions. The invasion of Ukraine by the Russian Federation on February 24, 2022, has impacted our operations in Kyiv significantly. Although our operations in Kyiv nearly ceased in the first quarter of 2022, we have since been able to gradually reorganize the internal services provided from that region through a combination of measures, including Ukrainian collaborators who have fled to other regions in their country now working from home, support provided by existing (and often enlarged) Materialise teams in other regions, the relocation of a number of Ukrainian collaborators outside of Ukraine, and, circumstances permitting, services provided from our Kyiv office, which we have re-opened and accommodated to try to cope with the challenges resulting from the continuous military strikes on key infrastructure in the country. While our people in Ukraine have shown, and continue to show, incredible resilience and professionalism, the situation in Ukraine remains unstable and uncertain and is expected to continue to have an impact on our operations, both financially and operationally. We expect that, as long as the armed conflict continues (and possibly for a period thereafter), this impact will continue and may even worsen, depending on the developments both geopolitically and in Ukraine. The ongoing additional mobilization for the Ukrainian army may also impact our operations. Although we are presently determined to continue to flexibly support our operations in Kyiv and at present do not see any reason to revise that strategy, we constantly monitor and evaluate the situation. Any change in strategy may have an additional negative impact on our results of operations and financial condition. We are unable to predict how the armed conflict in Ukraine will evolve and what the further political and economic repercussions will be. As a result, we are unable to assess with certainty its future impact on our business and operations, results of operations, financial condition, cash flows and liquidity. While we expect to suffer adverse effects, the severity is currently impossible to assess. Our international operations pose currency risks, which may adversely affect our results of operations and net income. Our results of operations may be affected by volatility in currency exchange rates and our ability to effectively manage our currency transaction risks. In general, we conduct our business, earn revenue and incur costs in the local currency of the countries in which we operate. During the year ended December 31, 2025, 68% of our revenue was generated, and approximately 78% of our total costs were incurred in euros. If the USD rate for €1.00 would have appreciated by 10%, the net result would have been €0.5 million higher, excluding the effect of intercompany positions and cash and term accounts held in USD. If the USD rate for €1 would have depreciated by 10%, the net result would have been €0.4 million lower, excluding the effect of intercompany positions and cash and term accounts held in USD. As we continue to expand internationally, our exposure to currency risks may increase. Historically, although we seek to monitor the ratio of revenues to expenses in certain foreign currencies, we have not managed all our foreign currency exposure in a manner that would eliminate the effects of changes in foreign exchange rates. Changes in exchange rates between the foreign currencies in which we do business and the euro will affect our revenue, cost of sales, and operating margins, and could result in exchange losses in any given reporting period. Changes in tax laws, treaties or regulations could adversely affect our financial results. Our future effective tax rates could be adversely affected by changes in tax laws, treaties and regulations, both internationally and domestically. For example, such changes may include possible changes to the innovation income deduction regime in Belgium or the way it proportionately impacts our effective tax rate. In addition, the Organization for Economic Cooperation and Development (OECD) Inclusive Framework of 145 jurisdictions continue to reshape international taxation through its two-pillar plan. The first pillar is focused on the allocation of taxing rights between countries for in-scope multinational enterprises that sell goods and services into countries with little or no local physical presence and is intended to apply to multinational enterprises with global revenues above €20 billion. The second pillar is focused on developing a global minimum tax rate of at least 15% applicable to in-scope multinational enterprises and is intended to apply to multinational enterprises with annual consolidated group revenue in excess of €750 million. We are actively monitoring our compliance obligations and the impact of the OECD pillar one and pillar two rules as they continue to be refined by the OECD and implemented by various national governments. However, it is possible that the OECD pillar one and pillar two rules, as implemented by various national governments, could adversely affect our effective tax rate or result in higher cash tax liabilities. An increase of our future effective tax rates could have a material adverse effect on our business, financial position, results of operations and cash flows. 14 Table of Contents Errors or defects in our software or other products could cause us to incur additional costs, lose revenue and business opportunities, damage our reputation and expose us to potential liability. Sophisticated software and complex 3D printed products may contain errors, defects or other performance problems at any point in the life of the product. If errors or defects are discovered in our current or future software or other products, we may not be able to correct them in a timely manner, or provide an adequate response to our customers. We may therefore need to expend significant financial, technical and management resources, or divert some of our development resources, in order to resolve or work around those defects. We may also experience an increase in our service and warranty costs. Particularly in the medical sector, errors or defects in our software or products could lead to claims by patients against us and our customers and expose us to lawsuits that may damage us and our customers’ reputations. Claims may be made by individuals or by classes of users. Our product liability and related insurance policies may not apply or sufficiently cover any product liability lawsuit that arises from defective software or products. Customers such as our collaboration partners may also seek indemnification for third party claims allegedly arising from breaches of warranties under our collaboration agreements. Errors, defects or other performance problems in our software or other products may also result in the loss of, or delay in, the market acceptance of our software, our products and related 3D printing or engineering services or postponement of customer deployment. Such difficulties could also cause us to lose customers and, particularly in the case of our largest customers, the potentially substantial associated revenue which would have been generated by our sales to companies participating in our customer’s supply chain. Technical problems, or the loss of a customer with a particularly important global reputation, could also damage our own business reputation and cause us to lose new business opportunities. Our operations are subject to environmental laws and other government regulations and emerging sustainability risks, including environmental, social and governance (ESG) matters, which could have a material adverse effect on our business, financial condition and results of operations or result in liabilities in the future. We are subject to local environmental laws and regulations governing our operations, including, but not limited to, emissions into the air and water and the use, handling, disposal and remediation of hazardous substances. A certain risk of environmental liability is inherent in our production activities. Under certain environmental laws, we could be held solely or jointly and severally responsible, regardless of fault, for the remediation of any hazardous substance contamination at our service centers and other facilities and the respective consequences arising out of human exposure to such substances or other environmental damage. We may not have been and may not be at all times in complete compliance with environmental laws, regulations and permits, and the nature of our operations exposes us to the risk of liabilities or claims with respect to environmental and worker health and safety matters. If we violate or fail to comply with environmental laws, regulations and permits, we could be subject to penalties, fines, restrictions on operations or other sanctions, and our operations could be interrupted. The cost of complying with current and future environmental, health and safety laws applicable to our operations, or the liabilities arising from past releases of, or exposure to, hazardous substances, may result in future expenditures. Our ability to ensure a resilient business that delivers long-term sustainable growth is reliant on our ability to identify current and emerging sustainability risks and legislative requirements that could adversely impact our business and ensure appropriate strategies are in place to manage such risks and requirements. Some of the key risks and requirements include: ● Growing expectations on how businesses respond to and address sustainability issues from customers, non-governmental organizations, ESG-focused investors and other stakeholders. The failure to meet these expectations may have adverse consequences, such as: active product delisting, negative non-governmental organization campaigns, loss of market share, omission from sustainability indices and adverse public perception or publicity; and ● Increased mandatory sustainability due-diligence and non-financial reporting and disclosure obligations, requiring businesses to take appropriate action or face regulatory penalties. This includes laws and regulations in the countries where we operate, such as, Carbon Border Adjustment Mechanism Regulation, the EU Corporate Sustainability Reporting Directive (CSRD), California’s Voluntary Carbon Market Disclosures Act. In particular, under CSRD, we are required, starting with the financial year ending December 31, 2025, to report on a broad range of sustainability-related impacts, risks and opportunities on the basis of the European Sustainability Reporting Standards which require, in particular, disclosures on environmental protection, social responsibility and treatment of employees, respect for human rights, anti-corruption, bribery and diversity. In connection with these reporting obligations, we will disclose ESG targets, policy and strategic plans, and conduct due diligence for our own operations and supply chain. As the CSRD requires reporting based on a “double materiality” assessment, we need to make both (i) an inside-out assessment of impact materiality (meaning a consideration of the impact of our corporate activity on sustainability matters) and (ii) an outside-in assessment of financial materiality (meaning a consideration of sustainability matters which, from the investor perspective, are material to our development, performance and financial position). 15 Table of Contents Our efforts to address current and emerging sustainability requirements could result in increased costs and divert management’s attention and resources from our business. At the same time, in certain jurisdictions, regulators have increasingly expressed or pursued opposing views, legislation and investment expectations with respect to sustainability initiatives. For example, in the United States in recent years, anti-ESG and anti-Diversity Equity and Inclusion (DEI) sentiment has gained momentum. Conflicting regulations and a lack of harmonization of ESG and DEI legal and regulatory environments across the jurisdictions in which we operate may create enhanced compliance risks and costs. We may also face increasing scrutiny from our clients, employees and other stakeholders relating to the appropriate role of ESG and DEI practices and disclosures. Failure to prepare for and meet evolving standards and expectations could result in regulatory penalties, investor backlash and diminished shareholder confidence. Any of these developments, alone or in combination, could have a material adverse effect on our business, financial condition and results of operations. If our 3D printing service center operations are disrupted, sales of our 3D printing services, including the medical devices that we print, may be affected, which could have an adverse effect on our results of operations. We have eight 3D printing service centers in Europe, the United States, Brazil and Japan, including our principal 3D printing service center located in Leuven, Belgium. If the operations of these facilities are materially disrupted, whether by fires or other industrial accidents, extreme weather, natural disasters, labor stoppages, acts of terror, or otherwise, we would be unable to fulfill customer orders for the period of the disruption, we would not be able to recognize revenue on orders, could suffer damage to our reputation, and we might need to negotiate sales terms to secure the commitment of new customers during the period of the disruption and perhaps longer. In addition, extreme weather and other natural disasters may become more intense or more frequent as a result of climate change. Depending on the cause of the disruption, we could incur significant costs to remedy the disruption and resume providing 3D printing services. Such a disruption could have an adverse effect on our results of operations. Our insurance policies may not provide adequate coverage for potential liabilities, including liabilities arising from litigation. In the ordinary course of business, we have been, and in the future may be, subject to various product and non-product related claims, lawsuits and administrative proceedings seeking damages or other remedies arising out of our commercial operations, including litigation related to defects in our software or other products. We maintain insurance to cover our potential exposure for a number of claims and losses. However, our insurance coverage is subject to various exclusions, self-retentions and deductibles, may be inadequate or unavailable to protect us fully, and may be cancelled or otherwise terminated by the insurer. Furthermore, we face the following additional risks related to our insurance coverage: ● we may not be able to continue to obtain insurance coverage on commercially reasonable terms, or at all, including with respect to our activities in the medical and the aerospace industry; ● we may be faced with types of liabilities that are not covered under our insurance policies, such as environmental contamination, terrorist attacks or alleged infringements of third parties’ intellectual property rights, and that exceed any amounts that we may have reserved for such liabilities; ● the amount of any liabilities that we may face may exceed our policy limits; and ● we may incur losses resulting from the interruption of our business that may not be fully covered under our insurance policies. Even a partially uninsured claim of significant size, if successful or if settled for a substantial amount of money, could have a material adverse effect on our business, financial condition, results of operations and liquidity. However, even if we successfully defend ourselves against any such claim, we could be forced to spend a substantial amount of money in litigation expenses, our management could be required to spend valuable time defending these claims and our reputation could suffer, any of which could adversely affect our results of operations. 16 Table of Contents We face potential liability related to the privacy and security of personal information we collect. In particular, but not exclusively, in connection with our Materialise Medical segment and the personalized wearables business we are pursuing within our Materialise Manufacturing segment, we may have access to personal information that is subject to a number of US federal and state, EU and other applicable foreign laws protecting the confidentiality of certain patient health or other private information, including patient records, and restricting the use and disclosure of that protected information. In addition, in our Materialise Software segment, we collect, transmit, process and store large amounts of proprietary or other sensitive data from our customers through our SaaS and cloud-based software applications, some of which are highly regulated. Moreover, the landscape of laws, regulations, and industry standards related to patient health and other private information, data privacy and cybersecurity is evolving globally. We may be subject to increased compliance burdens by regulators and our customers and the patients that we and our customers serve, as well as additional costs to oversee and monitor security risks. In the United States, we are subject to the Health Insurance Portability and Accountability Act, or HIPAA, the Health Information Technology for Economic and Clinical Health Act of 2009, regulations issued pursuant to these statutes, state privacy and security laws and regulations. These statutes, regulations and contractual obligations impose numerous requirements regarding the use and disclosure of personal health information with which we must comply. In addition, we are subject to data privacy and cybersecurity laws such as the California Consumer Privacy Act, or CCPA, as amended and expanded by the California Privacy Rights Act, or CPRA. The CCPA, as amended by the CPRA, requires, among other things, covered companies, including us, to provide new disclosures to California consumers and afford such consumers the ability to opt out of certain sales of personal information. We are undertaking appropriate steps to modify our data processing practices and policies to comply with data privacy and cybersecurity laws and expect to incur substantial costs and expenses in an effort to comply with such laws, including in connection with our development and deployment of SaaS and cloud-based software solutions. In the European Union, Regulation (EU) 2016/679 (the General Data Protection Regulation or GDPR), was adopted on April 27, 2016, and replaced the EU Data Protection Directive when it came into force on May 25, 2018. The GDPR introduced new data protection requirements in the European Union, unprecedented regulatory risk for non-compliant data processors and controllers and sizeable penalties for serious breaches — up to €20 million or 4% of global turnover, whichever is higher. The GDPR also significantly expands the territorial reach of existing EU data protection and privacy rules. Our business processes have been and continue to be modified in order to incorporate the requirements of the GDPR. In addition, in connection with its withdrawal from the European Union, the United Kingdom implemented the GDPR as of January 1, 2021 (as it existed on December 31, 2020 but subject to certain UK-specific amendments), or UK GDPR. In ensuring continued compliance with the EU regime, our transfer of any personal data from the European Union to the United States must be done in a manner which satisfies EU cross-border data transfer requirements. On July 10, 2023, the European Commission adopted its adequacy decision for the EU-US Data Privacy Framework. The decision concludes that the United States ensures an adequate level of protection – comparable to that of the European Union – for personal data transferred from the European Union to US companies under the new framework. On the basis of the adequacy decision, personal data may flow safely from the European Union to US companies participating in the EU-US Data Privacy Framework, without having to put in place additional data protection safeguards. The adequacy decision followed the adoption of Executive Order on “Enhancing Safeguards for United States Signals Intelligence Activities” by former US President Biden on October 7, 2022, and a regulation issued by the US Attorney General. These measures introduced new binding safeguards to address the points raised by Court of Justice of the European Union in its Schrems II decision of July 2020, ensuring that data may be accessed by US intelligence agencies only to the extent necessary and proportionate and establishing an independent and impartial redress mechanism to handle and resolve complaints from Europeans concerning the collection of their data for national security purposes. However, the EU-US Data Privacy Framework is currently subject to annulment proceedings before the Court of Justice of the European Union, which may affect its future validity. The safeguards that have been put in place by the US government in the area of national security (including the redress mechanism) apply to all data transfers under the GDPR to companies in the United States, regardless of the transfer mechanisms used. These safeguards therefore also facilitate the use of other tools, such as standard contractual clauses. We are investigating and are undertaking appropriate steps to mitigate the risks associated with these evolving data privacy laws and data transfer requirements. In late 2025, the European Commission proposed a comprehensive ‘Digital Omnibus’ legislative package aimed at harmonizing and simplifying the EU’s digital regulatory framework, including the GDPR, the ePrivacy Directive, the Data Act, and the AI Act. 17 Table of Contents If adopted, these proposals could materially affect our data processing activities and compliance obligations. Key proposed changes include: ● GDPR Refinement: Revisions to the definition of ‘personal data’ to adopt an entity-relative approach and the introduction of ‘legitimate interests’ as a formalized legal basis for processing personal data for AI model training and development. ● ePrivacy Integration: The transition of cookie and tracking technology regulations from the ePrivacy Directive into the GDPR framework, potentially altering how we manage user consent and automated ‘machine-readable’ privacy signals. ● Operational Relief: Proposed extensions to personal data breach notification timelines (from 72 to 96 hours in certain cases) and streamlined reporting via a single EU portal for cybersecurity and data incidents. ● AI Act Adjustments: A separate ‘Digital Omnibus on AI’ proposes delaying certain compliance deadlines for high-risk AI systems and reducing administrative burdens for mid-cap enterprises. While these measures are intended to reduce the ‘fragmentation’ of EU digital law and lower compliance costs, the legislative process remains ongoing. We cannot predict the final form of these regulations or their impact on our business. The transition to these new rules may require significant updates to our data governance systems, and any failure to align with the final requirements could result in increased litigation risk or regulatory enforcement under the GDPR’s existing penalty framework. In addition, the use and disclosure of personal health and other private information is subject to regulation in other jurisdictions in which we do business or expects to do business in the future. Some of these jurisdictions are not covered by an EU adequacy decision, and transfers of personal data to them are therefore subject to the conditions set out in Chapter 5 of the GDPR, including the requirement to implement appropriate safeguards. In addition, those jurisdictions may attempt to apply such laws extraterritorially or through treaties or other arrangements with European governmental entities. We might unintentionally violate such laws, and such laws may be modified and new laws may be enacted in the future which may increase the chance that we violate them. For example, each of the GDPR and the UK GDPR contains rules relating to the collection and processing of personal information, which are not identical to the current rules under national privacy laws and which contain more strict provisions. Any such developments, or developments stemming from enactment or modification of other laws, or the failure by us to comply with their requirements or to accurately anticipate the application or interpretation of these laws could create material liability for us, result in adverse publicity and negatively affect our medical business. Our failure to accurately anticipate the application or interpretation of these statutes, regulations and contractual obligations as we develop our medical and other products and services, a failure by us to comply with their requirements (e.g., evolving encryption and security requirements) or an allegation that defects in our medical or other products have resulted in noncompliance by our customers could create material civil and/or criminal liability for us, resulting in adverse publicity and negatively affecting our medical business. Any legislation or regulation in the area of privacy and security of personal information could affect the way we operate and could harm our business. The costs of compliance with, and the other burdens imposed by, these and other laws or regulatory actions may prevent us from selling our solutions or increase the costs associated with selling our products and services, and may affect our ability to invest in or jointly develop our products and services in the United States, the European Union and in foreign jurisdictions. Further, we cannot assure that our privacy and security policies and practices will be sufficient to protect us from liability or adverse publicity relating to the privacy and security of personal information. Risks relating to our Materialise Medical Segment and Regulatory Environment Our medical business, financial condition, results of operations and cash flows could be significantly and negatively affected by substantial government regulations. Our medical products are subject to rigorous regulation by the European Commission, the US Food and Drug Administration (FDA), and numerous other applicable governmental authorities. In general, the development, testing, manufacturing and marketing of our medical products are subject to extensive regulation and review by numerous governmental authorities in the European Union, the United States, the United Kingdom, Canada, Brazil, Japan and Australia, and in other markets where we are currently active or may become active in the future. The regulatory process requires the expenditure of significant time, effort and expense to bring new medical products to market, and we cannot be certain that we will receive regulatory approvals, certifications or registrations in any country in which we plan to market our medical products. 18 Table of Contents The laws and regulations, including the requirements for approvals, certifications or registrations and the time required for regulatory review, vary from country to country. For example, to market our medical products within the member states of the European Union, we are required to comply with the European Medical Device Regulation. Under the European Medical Device Regulation, all medical devices except custom-made and investigational devices must bear the CE mark. To obtain authorization to affix the CE mark to our medical products, a recognized European notified body must assess our quality systems and the product’s conformity to the requirements of the European Medical Device Regulation. Similarly, in the United States, we are required to obtain clearance or approval from the FDA prior to marketing our medical products. Moreover, any modification to a 510(k)-cleared device that could significantly affect its safety or efficacy, or that would constitute a major change in its intended use, technology, materials, packaging and certain manufacturing processes, may require a new 510(k) clearance or, possibly, a premarket approval, or PMA. The regulatory approval process outside the European Union and the United States may include all of the risks associated with obtaining CE or FDA clearance or approval in addition to other risks. Clearance or approval by the FDA in the United States, or conformity assessment and affixing a CE mark in the EEA does not ensure approval or certification by regulatory authorities in other countries, and approval or certification by one foreign regulatory authority does not ensure approval by regulatory authorities in other countries. We may be required to perform additional pre-clinical or clinical studies even if FDA clearance or approval, or the right to bear the CE label, has been obtained. We may not obtain regulatory approvals or certifications outside the European Union and the United States on a timely basis, if at all. If we fail to receive necessary approvals to commercialize our medical products in jurisdictions outside the European Union and the United States on a timely basis, or at all, our medical business, financial condition and results of operations could be adversely affected. As a manufacturer of medical devices, we participate in the Medical Device Single Audit Program, or MDSAP, which is a prerequisite for market entry in Canada, and which makes results from external audits by an accredited auditing organization available to the regulatory authorities of the United States, Canada, Brazil, Japan and Australia. A single audit is used in lieu of multiple separate audits or inspections by participating regulatory authorities or their representatives, reducing the overall number of audits or inspections. However, the auditing organization must inform regulatory authorities directly when certain non-conformity thresholds are reached, enabling participating regulatory authorities to immediately undertake actions appropriate for their jurisdictions. In addition, we are required to implement and maintain stringent reporting, labeling and record keeping procedures and make our facilities and operations subject to periodic inspections, both scheduled and unannounced, by the regulatory authorities. The medical device industry is also subject to a myriad of complex laws and regulations governing reimbursement, which varies from jurisdiction to jurisdiction in the European Union and which includes Medicare and Medicaid reimbursement in the United States as well as healthcare fraud and abuse laws, with these laws and regulations being subject to interpretation. In many instances, the industry does not have the benefit of significant regulatory or judicial interpretation of these laws and regulations. In certain public statements, governmental authorities have taken positions on issues for which little official interpretation was previously available. Some of these positions appear to be inconsistent with common practices within the industry but that have not previously been challenged. Various governmental agencies have become increasingly vigilant in recent years in their investigation of various business practices. Governmental and regulatory actions against us may result in various actions that could adversely impact our medical operations, including: ● the recall or seizure of products; ● the suspension or revocation of the authority necessary for the production or sale of a product; ● the delay of our ability to introduce new products into the market; ● the suspension of shipments from particular manufacturing facilities; ● the issuance of warning letters or untitled letters; ● the imposition of operating restrictions; ● the imposition of injunctions, fines and penalties; ● the curtailment or restructuring of our operations; 19 Table of Contents ● the exclusion of our products from being reimbursed by healthcare programs in the European Union or US federal and state healthcare programs (such as Medicare, Medicaid, Veterans Administration health programs and Civilian Health and Medical Program of the Uniformed Services); ● the delay or denial of customs clearance of our products for import in certain jurisdictions; and ● other civil or criminal sanctions against us. Failure to comply with applicable regulatory requirements could also result in civil actions against us and other unanticipated expenditures. Any of these actions, in combination or alone, or even a public announcement that we are under investigation for possible violations of these laws, could have a material adverse effect on our medical business, financial condition, results of operations and cash flows. Investigations or proceedings could cause us to incur significant legal expenses and divert our management’s attention from the operation of our business and we cannot assure that the costs of defending or resolving those investigations or proceedings would not have a material adverse effect on our financial condition, results of operations and cash flows. Similarly, if the healthcare providers or entities with whom we do business are found to be non-compliant with applicable laws, they may be subject to sanctions, which could also have a negative impact on us. In many of the countries in which we market our medical products, we are subject to regulations affecting, among other things, clinical efficacy, product standards, packaging requirements, labeling requirements, import/export restrictions, tariff regulations, duties and tax requirements. Many of the regulations applicable to our medical surgical guides, models, implants and software products in these countries are similar to those of the European Commission and the FDA. In addition, in many countries the national health or social security organizations require our medical products to be qualified before they may be marketed with the benefit of reimbursement eligibility. Failure to receive or delays in the receipt of relevant foreign qualifications also could have a material adverse effect on our medical business, financial condition, results of operations and cash flows. As the government regulators in the European Union, United States and elsewhere have become increasingly stringent, we may be subject to more rigorous regulation by governmental authorities in the future. Healthcare policy changes, including reimbursement levels and price regulation, could adversely affect us. New and amended Statutory provisions governing the clearance or approval, manufacture and marketing of a medical device may significantly affect our medical business and our medical products. Healthcare policies and programs also meaningfully affect the way healthcare is delivered and financed, and any changes may materially impact numerous aspects of our medical business. In particular, any changes that lower reimbursements or reduce medical procedure volumes could adversely affect our medical business and results of operations. Reimbursement may depend on obtaining a reimbursement code for our products. Obtaining a reimbursement code can be a lengthy and costly process and there is no guarantee that such a code can be obtained at satisfactory pricing levels or at all. Following the grant of a reimbursement code, third party payors have to agree to provide coverage. Moreover, governments, hospitals and other third party payors could reduce the amount of approved reimbursements or stop reimbursement altogether for a product. Changes to reimbursements for our products have negatively affected our sales volumes in the past and may unfavorably affect our future results of operations. Furthermore, initiatives sponsored by government agencies, legislative bodies and the private sector to limit the growth of healthcare costs, including price regulation and competitive pricing, are ongoing in markets where we do business. We could experience a negative impact on our medical business and results of operations due to increased pricing pressure in certain or all of the markets in which we operate. The use, including the misuse or off-label use, of our medical services and products may be deemed unauthorized use or improper promotion, which could harm our image in the marketplace or result in injuries that lead to product liability suits and could be costly to our business or result in regulatory sanctions. Medical decisions may only be made and operations may only be executed by trained professionals who are authorized to do so in the jurisdictions in which they operate. 20 Table of Contents Our medical services and products are generally designed to support surgeons in the planning and performance of their operations. In our medical software products set up, training and engineering support, we make it very clear that responsibility for medical decisions rests exclusively with the responsible surgeon, who is responsible for carefully reviewing and explicitly approving the surgical plan and/or the design of the medical device that is proposed by our software and engineers. Nonetheless, we cannot assure that patients, hospitals, surgeons or other parties will not try to hold us responsible for all or a part of the medical decisions underlying the operations that we support, exposing us to potential litigation or civil and criminal liability for unauthorized medical decision-making. Such actions or liability could lead governmental agencies to conclude that our products or services are used improperly, all of which could significantly damage our reputation and could materially impair the continued adoption of our medical services and product offering in the market. In the markets in which we operate, our medical promotional materials and training methods must comply with numerous applicable laws and regulations, including the prohibition on the promotion of a medical device for a use that has not been cleared or approved by the relevant regulator or supervisory body. Use of a device outside of its cleared or approved indication is known as “off-label” use. If a relevant governmental authority determines that our medical promotional materials or training constitute promotion of an off-label use, it could request that we modify our training or promotional materials or subject us to regulatory or enforcement actions, including the issuance of an untitled letter, a warning letter, injunction, seizure, civil fine and criminal penalties. In that event, our reputation could be damaged and adoption of our medical products would be impaired. Although we train our sales force not to promote our medical products for off-label uses, and our instructions for use in all markets specify that our products are not intended for use outside of those indications cleared for use, a competent regulatory agency could conclude that we have engaged in off-label promotion. In addition, there may be increased risk of injury if surgeons attempt to use our medical products off-label. Surgeons also may misuse our medical products or use improper techniques if they are not adequately trained, potentially leading to injury and an increased risk of product liability. Product liability claims are expensive to defend and could divert our management’s attention and result in substantial damage awards against us. Any of these events could adversely affect our medical business, results of operations and reputation and our ability to attract and retain customers for our products and services. If our marketed medical devices are defective or otherwise pose safety risks, the relevant governmental authorities could require their recall, or we may initiate a recall of our products voluntarily. The relevant governmental authorities may require the recall of commercialized products in the event of material deficiencies or defects in design or manufacture or in the event a product poses an unacceptable risk to health. Manufacturers, on their own initiative, may recall a product if any material deficiency in a device is found. A government-mandated or voluntary recall could occur as a result of an unacceptable risk to health, component failures, manufacturing errors, design or labeling defects or other deficiencies and issues. Recalls of any of our medical products would divert managerial and financial resources and have an adverse effect on our financial condition and results of operations. Any recall could impair our ability to produce our medical products in a cost-effective and timely manner in order to meet our customers’ demands. We also may be required to bear other costs or take other actions that may have a negative impact on our future revenue and our ability to generate profits. We may initiate voluntary recalls involving our medical products in the future that we determine do not require notification of the relevant regulatory body. If a governmental agency disagrees with our determinations, they could require us to report those actions as recalls. A future recall announcement could harm our reputation with customers and negatively affect our revenue. In addition, the relevant authority could take enforcement action for failing to report the recalls when they were conducted. Alternative medical solutions could outperform the solutions we offer, rendering our solutions obsolete Our Materialise Medical segment products and services compete with other innovative technologies that offer similar medical solutions. In addition, many of our competitors are continuing to innovate in the subsegments of the market that we seek to address. For example, our 3D printed surgical guides compete with robotics and navigational solutions, which offer alternative methods to guide a surgeon during an intervention. These current and future alternative technological solutions could outperform the solutions we offer and render our solutions obsolete. 21 Table of Contents If our Materialise Medical segment products cause or contribute to a death or a serious injury, or malfunction in certain ways, we will be subject to medical device reporting regulations, which can result in voluntary corrective actions or agency enforcement actions. In the EU, we must comply with the EU Medical Device Regulation vigilance reporting requirements, the purpose of which is to improve the protection of health and safety of patients, users and others by reducing the likelihood of reoccurrence of incidents related to the use of a medical device. Under this regulation, serious incidents must be reported to the competent authorities of the Member States of the EU. A serious incident is defined as any malfunction or deterioration in the characteristics or performance of a device made available on the market, including use-error due to ergonomic features, as well as any inadequacy in the information supplied by the manufacturer and any undesirable side-effect which, directly or indirectly led, might lead to or might have led to a serious public health threat, the death of a patient,user or of other persons or to a serious deterioration in their state of health. Serious incidents are evaluated by the EU competent authorities to whom they have been reported, and where appropriate, information is disseminated between them in the form of National Competent Authority Reports. The EU Medical Device Regulation vigilance reporting requirements are further intended to facilitate a direct, early and harmonized implementation of Field Safety Corrective Actions, or FSCAs, across the Member States of the EU where the device is in use. A FSCA is an action taken by a manufacturer to reduce a risk of death or serious deterioration in the state of health associated with the use of a medical device that is already placed on the market. A FSCA may include the recall, modification, exchange, destruction or retrofitting of the device. FSCAs must be communicated by the manufacturer or its legal representative to its customers and/or to the end users of the device through Field Safety Notices. In addition, under the FDA medical device reporting regulations, we are required to report to the FDA any incident in which our medical product has malfunctioned and would be likely to cause or contribute to a death or serious injury if the malfunction happened again. If we fail to report these events to the FDA within the required timeframes, or at all, the FDA could take enforcement action against us. Any adverse event involving our medical products could result in future voluntary corrective actions, such as recalls or customer notifications, or agency action, such as inspection, mandatory recall or other enforcement action. Any corrective action, whether voluntary or involuntary, as well as defending us in a lawsuit, will require the dedication of our time and capital, distract management from operating our business, and may harm our reputation and financial results. Our Materialise Medical segment’s 3D printing operations are required to operate within a quality management system that is compliant with the regulations of various jurisdictions, including the requirements of ISO 13485, and the US Quality System Regulation, which is costly and could subject us to enforcement action. We are subject to the regulations of various jurisdictions regarding the manufacturing process for our medical products, including the requirements of ISO 13485. Within the United States, we are required to comply with the Quality System Regulation, which covers, among other things, the methods of documentation of the design, testing, production, control, quality assurance, labeling, packaging, sterilization, storage and shipping of our medical products. Compliance with these regulations is costly and time-consuming. In addition, the FDA enforces the Quality System Regulation through periodic announced and unannounced inspections of manufacturing facilities. The failure by a manufacturer to comply with applicable statutes and regulations administered by the FDA and other regulatory bodies, or the failure to timely and adequately respond to any adverse inspectional observations or product safety issues, could result in, among other things, any of the following enforcement actions: ● untitled letters, warning letters, fines, injunctions, consent decrees and civil penalties; ● customer notifications or repair, replacement, refunds, recall, detention or seizure of our medical products; ● operating restrictions or partial suspension or total shutdown of production; ● refusing or delaying requests for 510(k) clearance or PMA of new products or modified products; ● withdrawing 510(k) clearances or PMAs that have already been granted; ● refusal to grant export approval for our medical products; or ● criminal prosecution. 22 Table of Contents Any regulatory enforcement actions could impair our ability to produce our medical products in a cost-effective and timely manner in order to meet our customers’ demands. We also may be required to bear other costs or take other actions that may have a negative impact on our future revenue and our ability to generate profits. Furthermore, our key component suppliers may not currently be or may not continue to be in compliance with all applicable regulatory requirements, which could result in our failure to produce our medical products on a timely basis and in the required quantities, if at all. Risks relating to our Intellectual Property If we are unable to obtain and maintain patent protection for our products or otherwise protect our intellectual property rights, our business could suffer. We rely on a combination of patents, copyrights, trademarks, trade secrets, confidentiality and other contractual arrangements with our employees, end users and others to maintain our competitive position. Our success depends, in part, on our ability to obtain patent protection for or maintain as trade secrets our proprietary products, technologies and inventions and to maintain the confidentiality of our trade secrets and know-how, operate without infringing upon the proprietary rights of others and prevent others from infringing upon our business proprietary rights. Despite our efforts to protect our proprietary rights, it is possible that competitors or other unauthorized third parties may obtain, copy, use or disclose or otherwise circumvent our technologies, software, inventions, processes or improvements. We cannot assure investors that any of our existing or future patents or other intellectual-property rights will be enforceable, will not be challenged, invalidated or circumvented, or will otherwise provide us with meaningful protection or any competitive advantage. In addition, our pending patent applications may not be granted and our existing patents may lapse if we fail to comply with procedural, documentary, feepayment and other requirements for obtaining and maintaining patent protection, and we may not be able to obtain foreign patents or may elect not to file foreign patent applications corresponding to our US, European or other patents. We intend to expand our business to certain countries that may not provide the same level of patent or other intellectual-property protection as the United States and the European Union. Even if we assert our patents or obtain additional patent or similar protection in such countries, effective enforcement of such patents or other rights may not be available. If our patents do not adequately protect our technology, our competitors may be able to offer products or services similar to ours or potential customers may gain illegal access to our proprietary technology. Our competitors may also be able to develop similar technology independently or design around our patents, and we may not be able to detect the unauthorized use of our proprietary technology or take appropriate steps to prevent such use. Moreover, ongoing changes to the US patent laws may impact our ability to obtain and enforce our intellectual-property rights. In recent years, the courts have interpreted US patent laws and regulations differently, and in particular the US Supreme Court has decided a number of patent cases and continues to actively review more patent cases than it has in the past. Some of these changes or potential changes may not be advantageous for us and may make it more difficult to obtain adequate patent protection or to enforce our patents against parties using them without a license or payment of royalties. These changes could increase the costs and uncertainties surrounding the prosecution of our patent applications and the enforcement or defense of our patent rights, all of which could have a material adverse effect on our business and financial condition. In addition, much of our technology is not protected by patents. We have devoted substantial resources to the development of our technology, trade secrets, know-how and other unregistered proprietary rights. While we enter into confidentiality and invention-assignment agreements intended to protect such rights, such agreements may be difficult and costly to enforce or may not provide adequate remedies if violated. Such agreements may be breached, and confidential information may be willfully or unintentionally used or disclosed in violation of the agreements, or our competitors or other parties may learn of the information in some other way. We cannot legally prevent one or more other companies from developing similar or identical technology to our unpatented technology and accordingly, it is likely that, over time, one or more other companies may be able to replicate our technology, thereby reducing our technological advantages. If we do not protect our technology or are unable to develop new technology that may be protected by patents or as trade secrets, we may face increased competition and lower revenue or gross margins, which may adversely affect our results of operations. We may incur substantial costs enforcing or acquiring intellectual property rights and defending against third party claims as a result of litigation or other proceedings. We have been and may in the future be subject or party, directly or indirectly, to claims, negotiations or complex, protracted litigation, arbitration or post-grant review proceedings in connection with the enforcement of our intellectual property and patent rights. 23 Table of Contents While we strive to avoid infringing the intellectual-property rights of third parties, we cannot provide any assurances that we will be able to avoid any claims, directed against us directly or against our collaboration partners or our other customers, that our products and technology, including the technology that we license from others, infringe the intellectual-property rights of third parties. Patent applications in the United States and most other countries are confidential for a period of time until they are published, and the publication of discoveries in scientific or patent literature typically lags behind the actual discoveries by several months or more. As a result, the nature of claims contained in unpublished patent filings around the world is unknown to us, and it cannot be certain that we were the first to conceive inventions covered by our patents or patent applications or that we were the first to file patent applications covering such inventions. Furthermore, it is not possible to know in which countries patent applicants may choose to extend their filings under the Patent Cooperation Treaty or other mechanisms, such as the European Patent Convention, or to predict the final scope of protection that may result from pending patent applications. Moreover, the patent landscape in the different fields in which we operate is heavily occupied and freedom-to- operate examinations are costly and time-consuming. We have not obtained extensive freedom-to-operate reports in the past for each and all of our products and services, nor do we intend to install on a general basis freedom to operate examinations for our future products and services. In addition, we may be subject to intellectual-property infringement claims from non-practicing entities, individuals, vendors and other companies, including those that are in the business of asserting patents, but are not commercializing products or services in the different fields in which we operate, or our collaboration partners or our other customers may seek to invoke indemnification obligations to involve us in such intellectual-property infringement claims. Furthermore, although we maintain certain procedures to help to ensure that the items we 3D print on behalf of customers do not infringe upon the intellectual-property rights of others, we cannot be certain that our procedures will be effective in preventing any such infringement. Intellectual-property disputes, litigation and arbitration, regardless of the merit or resolution, could cause us to incur significant costs in enforcing, or responding to, defending and resolving such claims. In addition, such claims may be costly and disruptive to our business operations by diverting attention and energy of management and key technical personnel, by prohibiting or otherwise impairing our ability to commercialize new or existing products or services and by increasing our costs of doing business. We may not prevail in any such dispute or litigation, and an adverse decision in any legal action involving intellectual-property rights, including any such action commenced by us, could limit the scope of our intellectual property rights and the value of the related technology. Third-party claims of intellectual-property infringement successfully asserted against us may require us to redesign infringing technology or enter into costly settlement or license agreements on terms that are unfavorable to us, prevent us from manufacturing or licensing certain of our products, subject us to injunctions restricting our sale of products and use of infringing technology, cause severe disruptions to our operations or the markets in which we compete, impose costly damage awards or require indemnification of our sales agents and end users. In addition, as a consequence of such claims, we may incur significant costs in acquiring the necessary third-party intellectual-property rights for use in our products and services or developing non-infringing substitute technology. Any of the foregoing developments may have a material adverse effect on our business, financial condition and results of operations. If disputes arise, we could lose rights that are important to our business or be subject to restrictions on the conduct of our business. We have license agreements with respect to certain intellectual-property that is important to our business and that may include exclusivity and non-competition undertakings. Disputes may arise between the counterparties to these agreements and us that could result in termination of these agreements. If we fail to comply with our obligations under our intellectual property-related agreements or misconstrue the scope of the rights granted to us or restrictions imposed on us under these agreements, the counterparties may have the right to terminate these agreements or sue us for damages or equitable remedies, including injunctive relief. Termination of these agreements, the reduction or elimination of our rights under these agreements, or the imposition of restrictions under these agreements that we have not anticipated may result in our having to negotiate new or reinstated licenses with less favorable terms, or to cease commercialization of licensed technology and products. This could materially adversely affect our business. Certain technologies and patents have been developed with collaboration partners and we may face restrictions on this jointly developed intellectual property. We have entered into collaborations with a number of industrial and medical-device companies and academic institutions, including Zimmer Biomet, Enovis, DePuy Synthes, Lima, Mathys, Siemens, and HP. We have, in some cases individually and in other cases along with our collaboration partners, filed for patent protection for a number of technologies developed under these agreements and may in the future file for further intellectual-property protection and/or seek to commercialize such technologies. Under some of these agreements, certain intellectual-property developed jointly by us and the relevant partner may be subject to joint ownership by us and the partner and our commercial use of such intellectual property may be restricted, or may require written consent from, or a separate agreement with, the partner. In other cases, we may not have any rights to use intellectual property solely developed and owned by the partner. If we cannot obtain commercial use rights for such jointly owned intellectual property or partner-owned intellectual property, our future product development and commercialization plans may be adversely affected. 24 Table of Contents Our use of open-source software may expose us to additional risks and harm our intellectual property. Some of our proprietary software, including some of our 3D printing software, may use or incorporate open-source software. Some open-source software licenses require users who distribute open-source software as part of their own software product to publicly disclose all or part of the source code to such software product or make available any derivative works of the open-source code on unfavorable terms or at no cost. We monitor, on an ongoing basis, whether our proprietary software, including our 3D printing software, would make use of any open-source software that could require us to disclose our proprietary source code, which could adversely affect our business. Risks relating to our ordinary shares and ADSs Our ordinary shares and ADSs may experience price and volume fluctuations and future sales of substantial amounts of ordinary shares or ADS on either or both of the stock exchanges on which they are listed, or the perception that such sales could occur, could adversely affect the market value of the securities or the interests of shareholders. Our ordinary shares currently trade on Euronext Brussels and the ADSs currently trade on Nasdaq. The stock markets in general have experienced extreme price and volume fluctuations that have often been unrelated or disproportionate to the operating performance of listed companies. Broad market and industry factors may negatively affect the market price of our ordinary shares and the ADSs on one or both exchanges, regardless of our actual operating performance. Because we are dual-listed, movements in the price or liquidity on one exchange may influence trading on the other, potentially amplifying volatility. The market price and liquidity of our securities may be higher or lower than the price you paid and may be significantly affected by numerous factors, some of which are beyond our control. These factors include: ● changes in macroeconomic or market conditions or trends in our industry or markets, such as inflation, recessions, fluctuations in interest rates, ongoing supply chain shortages, actual or perceived instability in the global banking system, changes in tariffs and trade restrictions, the results of local and national elections (including policy changes resulting from the U.S. presidential administration and EU institutions), international currency fluctuations, epidemics and pandemics, corruption, political instability and acts of war, such as the armed conflicts in Ukraine, Israel, Iran and the Middle East, or terrorism; ● significant volatility in the market price and trading volume of securities of companies in our sector, which is not necessarily related to the operating performance of these companies; ● the mix of products that we sell, and related services that we provide, during any period; ● delays between our expenditures to develop and market new products and the generation of sales from those products; ● changes in the amount that we spend to develop, acquire or license new products, technologies or businesses; ● changes in our expenditures to promote our products and services; ● success or failure of research and development projects of us or our competitors; ● announcements of acquisitions or divestures by us or one of our competitors; ● the general tendency towards volatility in the market prices of shares of companies that rely on technology and innovation; ● changes in regulatory policies or tax guidelines in either the U.S. or the EU, or in jurisdictions where we operate; ● changes or perceived changes in earnings or variations in operating results; and ● any shortfall in revenue or net income from levels expected by investors or securities analysts. Any of these could result in a material decline in the price of our ordinary shares or the ADSs on either or both exchanges. 25 Table of Contents Members of our board of directors and senior management own a significant percentage of our ordinary shares, have significant voting power and are able to exert significant influence over matters subject to shareholder approval. Further, the double voting rights that attach to certain of our ordinary shares could have a negative effect on the liquidity of our ordinary shares or the ADSs, which may adversely affect the market price of our ordinary shares or the ADSs. Members of our board of directors and senior management beneficially owned approximately 59.43% of our outstanding ordinary shares (including ordinary shares represented by ADSs), as of April 1st, 2026. Further, our restated articles of association provide that fully paid-up ordinary shares that have been continuously registered in the name of the same shareholder in our share register for at least two years carry double voting rights (meaning that such ordinary shares are entitled to two votes per share). Considering the double voting rights that attach to fully paid-up ordinary shares that have been continuously registered in the name of the same shareholder in our share register for at least two years, members of our board of directors and senior management have 73.28% of the voting rights as of March 1st, 2026. As a result, a relatively large proportion of our voting power is concentrated in a relatively small number of registered shareholders who hold fully paid-up shares that have been continuously registered in their name in our share register for at least two years. These shareholders have significant influence over the election of members of our board of directors and the outcome of corporate actions requiring shareholder approval, including dividend policy, mergers, share capital increases, amendments of our restated articles of association and other extraordinary transactions. For example, these shareholders may be able to influence the outcome of elections of members of our board of directors, amendments of our organizational documents, or approval of any merger, sale of assets, or other major corporate transactions. In addition, our restated articles of association provide that, as long as Wilfried Vancraen, our founder and a member of our board of directors, and Hilde Ingelaere, a member of our board of directors, who is also Mr. Vancraen’s spouse, and their three children, Linde, Sander (who is also a member of our board of directors) and Jeroen Vancraen, or collectively the Family Shareholders, control, directly or indirectly, in the aggregate at least 20% of the voting rights attached to our ordinary shares and if a Family Shareholder formulates a simple request to that effect, no more than six (6) directors may be appointed exclusively on the proposal of a majority of all Family Shareholders who, on the date of the appointment, hold at least 3% of the shares of the company, directly or indirectly. The number of candidates on the list of nominations provided by the Family Shareholders must exceed the number of mandates subject to the nomination right, and any vacancy of a director appointed on such proposal may only be filled by a candidate nominated by a majority of the other directors appointed on the recommendation of the Family Shareholders (if any). This concentration of ownership within this group of shareholders and the rights of the Family Shareholders prevent or discourage unsolicited acquisition proposals or offers for our ordinary shares or ADSs that you may feel are in your best interest as one of our shareholders. The interests of these existing shareholders or the Family Shareholders may not always coincide with your interests or the interests of other shareholders, and they may act in a manner that advances their best interests and not necessarily those of other shareholders, including seeking a premium value for their ordinary shares, which might affect the prevailing market price for our ordinary shares or the ADSs. In addition, the two-year holding period required for the double voting rights may adversely impact the liquidity and market price of our ordinary shares or the ADSs. The dilutive effect of our warrants could have an adverse effect on the future market price of our ordinary shares or the ADSs or otherwise adversely affect the interests of our shareholders. Based on outstanding granted warrants, as of December 31, 2025, there were outstanding granted warrants to subscribe for an aggregate of 350,000 ordinary shares, with 325,000 warrants at a weighted average exercise price of € 4.87 per share and 25,000 warrants at an exercise price of € 7.59 per share. The warrants likely will be exercised if the market price of ordinary shares or the ADSs equals or exceeds the applicable exercise price. To the extent such securities are exercised, additional ordinary shares will be issued, which would dilute the ownership of existing shareholders. 26 Table of Contents ADS holders may not have the same voting rights as the holders of our ordinary shares and may not receive voting materials in time to be able to exercise their right to vote. Further, the double voting rights that attach to certain of our ordinary shares are available only to holders who own their ordinary shares in registered form and not to ADS holders. Except as described in the deposit agreement related to the ADSs, holders of ADSs are not able to exercise voting rights attaching to the ordinary shares evidenced by the ADSs on an individual basis. Under the terms of the deposit agreement, holders of ADSs may instruct the depositary to vote the ordinary shares underlying their ADSs, but only if we ask the depositary to ask for their instructions. Otherwise, holders of ADSs are not able to exercise their right to vote, unless they withdraw our ordinary shares underlying the ADSs they hold to vote them in person or by proxy. However, holders of ADSs may not know about the meeting far enough in advance to withdraw those ordinary shares. If we ask for the instructions of holders of ADSs, the depositary, upon timely notice from us, will notify holders of ADSs of the upcoming vote and arrange to deliver our voting materials to them. Upon our request, the depositary will mail to holders of ADSs a shareholder meeting notice which contains, among other things, a statement as to the manner in which voting instructions may be given, including an express indication that such instructions may be given or deemed given to the depositary to give a discretionary proxy to a person designated by us if no instructions are received by the depositary from holders of ADSs on or before the response date established by the depositary. However, no voting instruction shall be deemed given and no such discretionary proxy shall be given with respect to any matter as to which we inform the depositary that (i) substantial opposition exists, or (ii) such matter materially and adversely affects the rights of shareholders. We cannot guarantee that holders of ADSs will receive the voting materials in time to ensure that they can instruct the depositary to vote their shares. In addition, the depositary’s liability to holders of ADSs for failing to execute voting instructions or for the manner of executing voting instructions is limited by the deposit agreement. As a result, holders of ADSs may not be able to exercise their right to give voting instructions or to vote in person or by proxy and they may not have any recourse against the depositary or our company if their shares are not voted as they have requested or if their shares cannot be voted. Furthermore, our restated articles of association provide that fully paid-up ordinary shares that have been continuously registered in the name of the same shareholder in our share register for at least two years carry double voting right. Only shareholders who own their shares in registered form are entitled to take advantage of these double voting rights and ADS holders are not entitled to double voting rights. ADS holders may not receive distributions on our ordinary shares represented by the ADSs or any value for them if it is illegal or impractical to make them available to holders of ADSs. Under the terms of the deposit agreement, the depositary for the ADSs has agreed to pay to ADS holders the cash dividends or other distributions it or the custodian receives on our ordinary shares or other deposited securities after deducting its fees and expenses. ADS holders will receive these distributions in proportion to the number of our ordinary shares their ADSs represent. However, in accordance with the limitations set forth in the deposit agreement, it may be unlawful or impractical to make a distribution available to holders of ADSs. As our company is listed on both Nasdaq and Euronext Brussels, certain distributions may be subject to additional legal, regulatory, tax, or currency conversion requirements under Belgian law and regulatory frameworks that differ from U.S. rules. Differences between jurisdictions in record dates, payment dates, accepted payment currencies, and applicable withholding taxes may also affect the timing and amount of distributions received by the depositary, and in turn, by ADS holders. In particular, coordination between the Belgian settlement system and the U.S. depositary process may lead to delays or added costs. We have no obligation to take any other action to permit the distribution of the ADSs, ordinary shares, rights or anything else to holders of ADSs. This means that ADS holders may not receive the distributions we make on our ordinary shares or any value from them if it is unlawful or impractical to make them available to ADS holders. These restrictions may have a material adverse effect on the value of the ADSs. We have no present intention to pay cash dividends on our ordinary shares in the foreseeable future and, consequently, investors’ only opportunity to achieve a return on their investment during that time is if the price of our ordinary shares or the ADSs appreciates. We have no present intention to pay cash dividends on our ordinary shares in the foreseeable future. Any recommendation by our board of directors to pay cash dividends will depend on many factors, including our financial condition, results of operations, legal requirements and other factors. Furthermore, pursuant to Belgian law, the calculation of amounts available for distribution to shareholders, as dividends or otherwise, must be determined on the basis of our non-consolidated statutory financial statements prepared under generally accepted accounting principles in Belgium, or Belgian GAAP. In addition, in accordance with Belgian law and our restated articles of association, we must allocate each year an amount of at least 5% of our annual net profit under our statutory non-consolidated accounts (prepared in accordance with Belgian GAAP) to a legal reserve until the reserve equals 10% of our share capital. Our legal reserve currently does not meet this requirement. As a consequence of these facts, there can be no assurance as to whether dividends or other distributions will be paid out in the future or, if they are paid, their amount. 27 Table of Contents As a foreign private issuer listed both in Belgium and the U.S., we are exempt from a number of rules under the U.S. securities laws and are permitted to file less information with the SEC than U.S. domestic issuers. This may limit the information available to holders of our ordinary shares and ADSs. We are a “foreign private issuer,” as defined in the rules and regulations of the SEC and, consequently, we are not subject to all of the disclosure requirements applicable to U.S. domestic issuers. For example, we are exempt from certain rules under the Exchange Act that regulate disclosure obligations and procedural requirements related to the solicitation of proxies, consents or authorizations applicable to a security registered under the Exchange Act. In addition, our officers, directors and principal shareholders are exempt from the “short-swing” profit recovery provisions of Section 16 of the Exchange Act and related rules with respect to their purchases and sales of our securities. Moreover, we are not required to file periodic reports and consolidated financial statements with the SEC as frequently or as promptly as U.S. domestic issuers. While we are subject to Belgian disclosure and transparency obligations applicable to Belgian listed companies, these obligations differ in significant respects from those applicable to U.S. domestic issuers. Accordingly, there may be less publicly available information concerning our company than there is for U.S. public companies. As a foreign private issuer, we file an annual report on Form 20-F within four months of the close of each year ended December 31 and furnish reports on Form 6-K relating to certain material events promptly after we publicly announce these events. However, although we intend to continue to issue quarterly financial information, because of the above exemptions for foreign private issuers, we are not required to do so, and, therefore, our shareholders and ADS holders will not be afforded the same protections or information generally available to investors holding shares in public companies organized in the United States. We may lose our foreign private issuer status in the future, which could result in significant additional costs and expenses. As a foreign private issuer, we are not required to comply with all the periodic disclosure and current reporting requirements of the Exchange Act and related rules and regulations. The determination of foreign private issuer status is made annually on the last business day of an issuer’s most recently completed second fiscal quarter. Accordingly, we will next make a determination with respect to our foreign private issuer status on June 30, 2026. There is a risk that we will lose our foreign private issuer status in the future. We would lose our foreign private issuer status if, for example, more than 50% of our assets are located in the United States and more than 50% of the voting power of our outstanding ordinary shares are held of record by U.S. residents. As of December 31, 2025, 3% of our assets were located in the United States. The regulatory and compliance costs to us under U.S. securities laws as a U.S. domestic issuer may be significantly greater than the costs we incur as a foreign private issuer. If we are not a foreign private issuer, we will be required to file periodic reports and registration statements on U.S. domestic issuer forms with the SEC, which are more detailed and extensive in certain respects than the forms available to a foreign private issuer. We would be required under current SEC rules to prepare our consolidated financial statements in accordance with U.S. GAAP and modify certain of our policies to comply with corporate governance practices associated with U.S. domestic issuers. Such conversion and modifications would involve significant additional costs. In addition, we may lose our ability to rely upon exemptions from certain corporate governance requirements on U.S. stock exchanges that are available to foreign private issuers such as the ones described above and exemptions from procedural requirements related to the solicitation of proxies. If we fail to maintain an effective system of internal control over financial reporting in the future, we may not be able to accurately report our financial condition, results of operations or cash flows, which may adversely affect investor confidence in us. The Sarbanes-Oxley Act requires, among other things, that we maintain effective internal control over financial reporting and disclosure controls and procedures. In particular, we are required, under Section 404 of the Sarbanes-Oxley Act, to perform system and process evaluations and testing of our internal controls over financial reporting to allow management and our independent registered public accounting firm to report on the effectiveness of our internal control over financial reporting. This assessment must include disclosure of any material weaknesses in our internal control over financial reporting identified by our management or our independent registered public accounting firm. A material weakness is a control deficiency, or combination of control deficiencies, in internal control over financial reporting that results in more than a reasonable possibility that a material misstatement of annual or interim consolidated financial statements will not be prevented or detected on a timely basis. Section 404 of the Sarbanes-Oxley Act also generally requires an attestation from our independent registered public accounting firm on the effectiveness of our internal control over financial reporting. Our independent registered public accounting firm may issue a report that is adverse in the event it is not satisfied with the level at which our controls are documented, designed or operating. Where applicable, our remediation efforts may not enable us to avoid a material weakness in the future. 28 Table of Contents We cannot assure you that there will not be material weaknesses or significant deficiencies in our internal control over financial reporting in the future. Any failure to maintain internal control over financial reporting could severely inhibit our ability to accurately report our financial condition, results of operations or cash flows. If we are unable to conclude that our internal control over financial reporting is effective, or if our independent registered public accounting firm determines we have a material weakness or significant deficiency in our internal control over financial reporting, we could lose investor confidence in the accuracy and completeness of our financial reports, the market price of our ordinary shares or the ADSs could decline, and we could be subject to sanctions or investigations by the Nasdaq Stock Market, the SEC or other regulatory authorities. Failure to remedy any material weakness in our internal control over financial reporting, or to implement or maintain other effective control systems required of public companies, could also restrict our future access to the capital markets. We have incurred and will incur significant increased costs as a result of operating as a company whose ADSs are publicly traded in the United States, and whose ordinary shares are publicly traded on Euronext Brussels, and our management is required to devote substantial time to new compliance initiatives. As a company whose ADSs are publicly traded in the United States, and whose ordinary shares are listed in Euronext Brussels, we have incurred and will incur significant legal, accounting, insurance and other expenses that we did not incur prior to our initial public offering and prior to our Euronext Brussels listing. In addition, the Sarbanes-Oxley Act, the Dodd-Frank Wall Street Reform and Consumer Protection Act and related rules implemented by the SEC and the Nasdaq Stock Market as well as Belgian corporate law, the Euronext Brussels market rules, and regulations of the Belgian Financial Services and Markets Authority (FSMA) impose various requirements on public companies, including requiring establishment and maintenance of effective disclosure and financial controls in line with the rules applicable to both jurisdictions. These costs have increased now that we are no longer an emerging growth company eligible to rely on exemptions under the JOBS Act from certain disclosure and governance requirements and as we now also comply with Belgian transparency obligations, dual market disclosure coordination, and European Market Abuse Regulation (MAR) requirements. Our management and other personnel need to devote a substantial amount of time to these compliance initiatives. Moreover, these rules and regulations increase our legal and financial compliance costs and make some activities more time-consuming and costly. These laws and regulations could also make it more difficult and expensive for us to attract and retain qualified persons to serve on our board of directors or our committees. Furthermore, if we are unable to satisfy our obligations as a public company, we could be subject to delisting of the ADSs and/or ordinary shares, fines, sanctions and other regulatory action and potentially civil litigation. In order to satisfy our obligations as a dual listed company, we may need to hire or engage additional qualified accounting and financial personnel and consultants with appropriate experience. As a dual listed company, we are required to establish and maintain effective internal controls over financial reporting and disclosure controls and procedures. In order to establish and maintain this control environment, we have hired accounting and financial personnel and engaged consultants with experience and technical accounting knowledge, but we may need to hire or engage additional personnel and consultants to further our efforts. It is difficult to recruit and retain qualified personnel and consultants, and our operating expenses and operations have been and may continue to be impacted by the costs of their employment or engagement. Further, these efforts may divert management’s attention from their day-to-day responsibilities. ADS holders may be subject to limitations on the transfer of their ADSs. ADSs are transferable on the books of the depositary. However, the depositary may close its books at any time or from time to time when it deems doing so expedient in connection with the performance of its duties. The depositary may close its books from time to time for a number of reasons, including in connection with corporate events such as a rights offering, during which time the depositary needs to maintain an exact number of ADS holders on its books for a specified period. The depositary may also close its books in emergencies, and on weekends and public holidays. The depositary may refuse to deliver, transfer or register transfers of the ADSs generally when our share register or the books of the depositary are closed, or at any time if we or the depositary thinks that it is advisable to do so because of any requirement of law or of any government or governmental body, or under any provision of the deposit agreement, or for any other reason in accordance with the terms of the deposit agreement. As a result, ADS holders may be unable to transfer their ADSs when they wish to. 29 Table of Contents If securities or industry analysts do not publish research or reports about our business, or if they adversely change their recommendations regarding the ADSs or our ordinary shares, the market price for the ADSs and/or the ordinary shares and trading volume could decline. The trading market for the ADSs on Nasdaq and for our ordinary shares on Euronext Brussels is influenced by research or reports that industry or securities analysts publish about our business. We may receive coverage from analysts focused on U.S. markets, European markets, or both, and differing views or recommendations in each market could lead to volatility or price divergence between the ADSs and the ordinary shares. If one or more analysts who cover us downgrade the ADSs or our ordinary shares, the market price for the ADSs or ordinary shares would likely decline. If one or more of these analysts cease to cover us or fail to regularly publish reports on us, we could lose visibility in the financial markets, which, in turn, could cause the market price or trading volume for the ADSs and/or ordinary shares to decline. It may be difficult for investors outside Belgium to serve process on or enforce foreign judgments against us or our directors and senior management. We are a Belgian limited liability company whose ordinary shares are listed on Euronext Brussels and whose ADSs are listed on Nasdaq. Our dual listing means that investors may seek to bring actions in either the United States or Belgium, but practical and legal barriers may limit enforcement across jurisdictions. None of the members of our board of directors and senior management is a resident of the United States. All or a substantial portion of the assets of such non-resident persons and most of our assets are located outside the United States. As a result, it may not be possible for investors to effect service of process upon such persons or on us or to enforce against them or us a judgment obtained in U.S. courts. Original actions or actions for the enforcement of judgments of U.S. courts relating to the civil liability provisions of the federal or state securities laws of the United States are not directly enforceable in Belgium. The United States and Belgium do not currently have a multilateral or bilateral treaty providing for reciprocal recognition and enforcement of judgments, other than arbitral awards, in civil and commercial matters. In order for a final judgment for the payment of money rendered by U.S. courts based on civil liability to produce any effect on Belgian soil, it is accordingly required that this judgment be recognized or be declared enforceable by a Belgian court in accordance with Articles 22 to 25 of the 2004 Belgian Code of Private International Law. Recognition or enforcement does not imply a review of the merits of the case and is irrespective of any reciprocity requirement. A U.S. judgment will, however, not be recognized or declared enforceable in Belgium if it infringes upon one or more of the grounds for refusal which are exhaustively listed in Article 25 of the Belgian Code of Private International Law. These grounds mainly require that the recognition or enforcement of the foreign judgment should not be a manifest violation of public policy, that the foreign courts must have respected the rights of the defense, that the foreign judgment should be final, and that the assumption of jurisdiction by the foreign court may not have breached certain principles of Belgian law. In addition to recognition or enforcement, a judgment by a federal or state court in the United States against us may also serve as evidence in a similar action in a Belgian court if it meets the conditions required for the authenticity of judgments according to the law of the state where it was rendered. The findings of a federal or state court in the United States will not, however, be taken into account to the extent they appear incompatible with Belgian public policy. Similar legal hurdles may apply for actions brought in Belgian courts to be recognized or enforced in the United States, as there is no treaty on reciprocal enforcement of Belgian judgments in U.S. courts. This may further limit investors’ ability to obtain or enforce remedies across both of our listing jurisdictions. Holders of ADSs are not treated as shareholders of our company. Holders of ADSs with underlying shares in a Belgian limited liability company are not treated as shareholders of our company, unless they withdraw our ordinary shares underlying the ADSs that they hold. The depository is the holder of the ordinary shares underlying the ADSs. Holders of ADSs therefore do not have any rights as shareholders of our company, other than the rights that they have pursuant to the deposit agreement. We are a Belgian limited liability company listed in the U.S. and in Belgium, and shareholders of our company may have different and, in some cases, more limited shareholder rights than shareholders of a listed company in Belgium or of a U.S. listed corporation. We are organized as a limited liability company (naamloze vennootschap / société anonyme) under the laws of Belgium. Our corporate affairs are governed by Belgian corporate law. From a Belgian corporate law point of view, we qualify as a listed company (genoteerde vennootschap / société cotée) because our securities are listed on Euronext Brussels, a regulated market in the EEA, and we are also a listed company in the U.S. because our ADSs are traded on Nasdaq. As a Belgian listed company, certain provisions of Belgian corporate law applicable to listed companies apply to us. However, Belgian corporate law still differs in significant ways from U.S. federal and state laws applicable to U.S. listed corporations, which may result in our shareholders not enjoying certain rights and protections generally afforded to shareholders of U.S. companies. Investors should also be aware that the rights provided to our shareholders under Belgian corporate law and our restated articles of association differ in certain respects from the rights that our shareholders would typically enjoy as a shareholder of a U.S. corporation under applicable U.S. federal and state laws. 30 Table of Contents Under Belgian corporate law, except in certain limited circumstances, our shareholders may not ask for an inspection of our corporate records, while under Delaware corporate law any shareholder, irrespective of the size of his or her shareholdings, may do so. Shareholders of a Belgian corporation are also unable to initiate a derivative action, a remedy typically available to shareholders of U.S. companies, in order to enforce a right of our company, in case we fail to enforce such right ourselves, other than in certain cases of director liability under limited circumstances. In addition, a majority of our shareholders may release a director from any claim of liability we may have, including if he or she has acted in bad faith or has breached his or her duty of loyalty, provided that the shareholders were fully informed and that the relevant acts are accurately reflected in the annual accounts, which were approved before discussing the discharge. Additionally, for breaches of the articles of association or the law, there is an additional requirement: these acts must have been explicitly mentioned in the agenda of the convening notice to the shareholders’ meeting. In contrast, most U.S. federal and state laws prohibit a company or its shareholders from releasing a director from liability altogether if he or she has acted in bad faith or has breached his or her duty of loyalty to the company. Finally, Belgian corporate law does not provide any form of appraisal rights in the case of a business combination. For additional information on these and other aspects of Belgian corporate law and our restated articles of association, see “Item 10. Additional Information—B. Memorandum and Articles of Association.” As a result of these differences between Belgian corporate law and our restated articles of association, on the one hand, and U.S. federal and state laws, on the other hand, in certain instances, investors could receive less protection as a shareholder of our company than they would as a shareholder of a U.S. corporation. As a foreign private issuer listed both on Euronext Brussels and Nasdaq, we are not subject to certain Nasdaq Stock Market corporate governance rules applicable to U.S. listed companies. We rely on provisions in the Listing Rules of the Nasdaq Stock Market that permit us to follow our home country corporate governance practices with regard to certain aspects of corporate governance. This allows us to follow Belgian corporate law and the Belgian Code of Companies and Associations, which differ in significant respects from the corporate governance requirements applicable to U.S. companies listed on the Nasdaq Global Select Market. See “Item 16G. Corporate Governance.” Holders of ADSs or ordinary shares have limited rights to call shareholders’ meetings or to submit shareholder proposals, which could adversely affect their ability to participate in the governance of our company. Except under limited circumstances, only the board of directors may call a shareholders’ meeting. Shareholders who collectively own at least 10% of the ordinary shares of our company may require the board of directors or the statutory auditor to convene a special or an extraordinary general meeting of shareholders. In addition, shareholders representing at least 3% of our outstanding ordinary shares have the right to request that items be placed on the agenda of a shareholders’ meeting or to submit proposals for resolutions. As a result, the ability of individual holders of the ADSs or ordinary shares to influence the governance of our company is limited. Holders of the ADSs have limited recourse if we or the depositary fail to meet our respective obligations under the deposit agreement or if they wish to involve us or the depositary in a legal proceeding. The deposit agreement expressly limits the obligations and liability of us and the depositary. Neither we nor the depositary will be liable to the extent that liability results from the fact that we: ● are prevented or hindered in performing any obligation by circumstances beyond their control; ● exercise or fail to exercise discretion under the deposit agreement; ● perform our obligations without negligence or bad faith; ● take any action based upon advice of or information from legal counsel, accountants, any person presenting shares for deposit, any holder of the ADSs or any other qualified person; or ● rely on any documents we believe in good faith to be genuine and properly executed. In addition, neither we nor the depositary has any obligation to participate in any action, suit or other proceeding in respect of the ADSs which may involve us in expense or liability unless it is indemnified to our satisfaction. These provisions of the deposit agreement will limit the ability of holders of the ADSs to obtain recourse if we or the depositary fails to meet our respective obligations under the deposit agreement or if they wish to involve us or the depositary in a legal proceeding. 31 Table of Contents Investors may not be able to participate in equity offerings, and ADS holders may not receive any value for rights that we may grant. In accordance with Belgian corporate law, our restated articles of association provide for preferential subscription rights to be granted to our existing shareholders to subscribe on a pro rata basis for any issue for cash of new shares, convertible bonds or warrants that are exercisable for cash, unless such rights are cancelled or limited by resolution of our shareholders’ meeting or the board of directors. Our shareholders’ meeting or board of directors may cancel or restrict such rights in future equity offerings. In addition, certain shareholders (including those in the United States, Australia, Canada or Japan) may not be entitled to exercise such rights even if they are not cancelled unless the rights and related shares are registered or qualified for sale under the relevant legislation or regulatory framework. This means that even though our ordinary shares are listed on Euronext Brussels and our ADSs are listed on the Nasdaq investors in either market may be excluded from participating in a particular offering. As a result, there is the risk that investors may suffer dilution of their shareholding should they not be permitted to participate in preference right equity or other offerings that we may conduct in the future. We may also limit the exercise of rights by shareholders in certain jurisdictions if we distribute rights in connection with other changes to our capital structure, like a distribution of rights to tender our shares to us for redemption in connection with an issuer tender offer, resulting in such shareholders being unable to participate in such transactions. If rights are granted to our shareholders, as the case may be, but if by the terms of such rights offering or other transaction, or for any other reason, the depositary may not either make such rights available to any ADS holders or dispose of such rights and make the net proceeds available to such ADS holders, then the depositary may allow the rights to lapse, in which case ADS holders will receive no value for such rights. Shareholders in jurisdictions with currencies other than the euro face additional investment risk from currency exchange rate fluctuations in connection with their holding of our ordinary shares or ADSs. Any future payments of cash dividends on our ordinary shares will be denominated in euros. For ADS holders, the dividends will be converted by the depositary into U.S. dollars prior to distribution. The U.S. dollar—or other currency—equivalent of any dividends paid on our ordinary shares or ADSs or received in connection with any sale of our ordinary shares could be adversely affected by the depreciation of the euro against these other currencies. Fluctuations in the exchange rate between the euro and the U.S. dollar may increase the risk of holding our ADSs and ordinary shares. Our ordinary shares currently trade on Euronext Brussels in euro and our ADSs trade on Nasdaq in U.S. dollars. Fluctuations in the exchange rate between the euro and the U.S. dollar may result in temporary differences between the value of our ordinary shares and ADSs, which may result in heavy trading by investors seeking to exploit such differences. We do not expect to be a passive foreign investment company for U.S. federal income tax purposes; however, there is a risk that we may be classified as a passive foreign investment company, which could result in materially adverse U.S. federal income tax consequences to U.S. investors in our ordinary shares or ADSs. We do not expect to be a passive foreign investment company, or a PFIC. However, the application of complex U.S. federal income tax rules concerning the classification of our assets and income, and the application of these rules is uncertain in some respects. Additionally, certain aspects of the tests will be outside our control; therefore, no assurance can be given that we will not be classified as a PFIC for any taxable year. If you are a U.S. taxpayer and we are determined to be a PFIC at any time during your holding period, you may be subject to materially adverse consequences, including additional tax liability and tax filing obligations. See “Item 10. Additional Information—E. Taxation—U.S. Taxation—Passive Foreign Investment Company.” Changes in our United States federal income tax classification, or that of our subsidiaries, could result in adverse tax consequences to our 10% or greater U.S. shareholders. We do not believe that we, or any of our non-U.S. subsidiaries, are controlled foreign corporations, or CFCs, based upon the ADSs or ordinary shares owned directly by U.S. shareholders. However, we or certain of our non-U.S. subsidiaries may be classified as CFCs depending on the U.S. holdings of certain of our non-U.S. shareholders. This classification could cause significant and adverse U.S. tax consequences for our U.S. shareholders that own, or are considered to own, as a result of the attribution rules, 10% or more of the voting power or value of the stock of us or our non-U.S. subsidiaries, or a 10% U.S. shareholder, or any person who becomes a 10% U.S. shareholder under the U.S. Federal income tax law applicable to owners of CFCs. Therefore, we would advise our 10% U.S. shareholders (if any) and persons considering becoming 10% U.S. shareholders to consult their tax advisors regarding the U.S. Federal income tax law applicable to owners of CFCs. 32 Table of Contents

B. Business Overview Our Mission Our mission is to innovate product development that results in a better and healthier world, through our software and hardware infrastructure, and an in-depth knowledge of additive manufacturing. Our Company We are a leading provider of additive manufacturing and medical software tools and of sophisticated 3D printing services. With our knowledge, products and services, we empower our customers’ use of additive manufacturing technology, in general, and we enable certain specific and significant applications of additive manufacturing, in particular. In both instances, we seek to empower the choice for sustainability through the use of additive manufacturing. The customers of our general software tools and 3D printing services are active in a wide variety of industries, including healthcare, automotive, aerospace, art and design and consumer products. The significant additive manufacturing applications that we are more deeply and more directly involved in currently include applications for orthopedic devices, cranio maxillo facial devices, eyewear and footwear. As of December 31, 2025, our team consisted of 2,556 full-time equivalent employees, or FTEs, and fully dedicated consultants. Our portfolio of intellectual property featured 529 granted patents and 128 pending patent applications as of December 31, 2025. For the year ended December 31, 2025, we generated € 267.6 million of revenue, representing a 0.3% increase over the prior year, a net profit of € 7.7 million, an Adjusted EBIT of € 10.6 million and an Adjusted EBITDA of € 32.4 million. For a description of Adjusted EBIT and Adjusted EBITDA and a reconciliation of our net profit to our Adjusted EBIT and Adjusted EBITDA, see “Item 5. Operating and Financial Review and Prospects—A. Operating Results—Other Financial Information.” 33 Table of Contents Our Core Competencies Our established and proven business model integrates our three research-based core competencies: (i) software development, (ii) 3D printing, and (iii) engineering for 3D printing, which act as complementary incubators for our new products and function as integrated support centers for our existing products. The interaction and synergies among our software development, 3D printing and engineering teams position us well to continuously develop and support innovative applications of 3D printing that often integrate all three core competencies. Software Development (Software). Our expertise in developing 3D printing software originated from our efforts to enable 3D printing applications and to continually improve processes within our own additive manufacturing operations. Our software development encompasses software tools that are used in industrial 3D printing environments as well as in medical environments that are based on computed tomography (CT) and magnetic resonance imaging (MRI). As a result of our continued deployment over the course of 35 years of human, intellectual and economic capital to software development, a number of our products, including Magics and Mimics, have evolved into industry-leading flagship products. We have an established quality management system for the development of our industrial software products that is ISO 9001:2015 certified.

We believe that our customers benefit significantly from the synergistic interplay between our core competencies and the three market segments on which we focus and which provide regular end-user feedback to the product development and support teams within our core competencies. 34 Table of Contents Our Materialise Software Segment In our Materialise Software segment, we offer proprietary software worldwide through programs and platforms that enable companies to set up efficient, reliable and sustainable 3D printing production. Our software supports OEMs and 3D printing service bureaus both large and small that are producing a variety of parts for their customers and addresses the needs of large corporations producing at volume, either through significant serial manufacturing or mass customization. In all of these environments, we believe our software enables both operational excellence and flexibility. We work directly with many 3D printing machine manufacturers to enable and enhance the functionality of 3D printers and of 3D printing operations. We have developed software that interfaces between almost all types of industrial 3D printers, and various software applications and capturing technologies, including computer-aided design (or CAD)/computer-aided manufacturing (or CAM) packages and 3D scanners, by enabling data preparation and process planning and execution. Our programs interface with machines manufactured by leading original equipment manufacturers, or OEMs, including but not limited to EOS GmbH, HP Inc., Renishaw PLC, Nikon SLM Solutions AG, Stratasys Ltd., Trumpf (DUBAG Group GmbH), Uniontech Corporation, Colibrium and Voxeljet AG. In addition, we have entered into partnership agreements with leading CAD, CAM and product lifecycle management, or PLM, companies such as Siemens, and PTC, for the integration of our additive manufacturing technology into Siemens’ NX software, and PTC’s Creo software. This enables the streamlining of the design to manufacturing process for products being produced by additive manufacturing. We have also established connectivity by opening our platform and allowing integration with broader ecosystems such as post processing solutions like AMFlow. We offer software that enables our customers to more efficiently organize the entire workflow of a 3D printing operation with multiple 3D printing machines, many operators and complex data flow and logistical requirements. We believe that the capabilities of our software products and their unique compatibility with many 3D printing systems continue to set standards in the professional 3D printing software market. Customers operating machines from multiple OEMs and customers running large 3D printing operations are among those who may benefit the most from our software packages and we believe that in many cases those customers demand compatibility with our software from the systems of OEMs. As of December 31, 2025, our Materialise Software segment had a team of approximately 275 FTEs and fully dedicated consultants, with approximately 33% based at our headquarters in Belgium and the remaining employees distributed throughout our local field offices in China, Colombia, Germany, Japan, Malaysia, Spain, South Korea, Ukraine, the United Kingdom and the United States. Business Model. We generate revenue in our Materialise Software segment from our software licenses, maintenance contracts, hardware controller sales for our Materialise Controllers and custom software development services. Additionally, we offer consultancy and training services. We license our software products to our customers on either a time-based or perpetual basis, in which case we offer annual maintenance contracts that provide for software updates and support. In addition, we also provide a number of cloud-based solutions. Making use of, among others, our CO-AM ecosystem, we are significantly accelerating the migration of our software solutions to the cloud, which we intend to offer along with our license-based solutions. We charge our custom software development services either on a time and material or on a fixed-cost basis. For the years ended December 31, 2025, 2024, and 2023, our Materialise Software segment generated revenue of € 40.9 million, € 43.9 million, and € 44.4 million, respectively, representing 15.3%, 16.5%, and 17.4%, respectively, of our total revenue. Software. We have a diversified portfolio comprised of software applications addressing different 3D printing market opportunities. Our decades of experience in the additive manufacturing industry are reflected in the sophisticated 3D printing software and business management tools we provide for our customers. We believe that each of our software applications is, or has the potential of becoming, one of the leading technologies in its domain. We believe that our neutral platform approach positions our software to drive greater innovation and choice across the 3D printer software ecosystem, and provides 3D printer users with more powerful and flexible printing capabilities. 35 Table of Contents In particular, we offer the following software applications: ● Magics. Magics enables customers to import a wide variety of CAD formats and to the industry standard file formats 3MF and STL, as well as to the enriched BREP and MeshREP data format proprietary to us, ready for additive manufacturing. Magics’ applications include repairing and optimizing 3D models; analyzing parts; making process-related design changes on customers’ input files; designing support structures; documenting customer projects; nesting multiple parts in a single print run; and process planning. Our Magics product suite is enhanced with modules that further expand functionality and utility for our customers. For instance, the Magics Import Module plays an important role in efficiently moving CAD designs through to manufactured products by importing nearly all standard CAD formats into Magics. The Magics Structures Module was designed to help customers to reduce weight and material usage in their designs. We also have developed logistical modules such as the Magics SG Module, which offers tools for support structure design during the 3D printing process, and the Magics Sintermodule, which offers solutions for automated part nesting, protecting small and fragile parts and locating them after building. The Magics Simulation Module enables our users to simulate the build process virtually and optimizes the build preparation based on the results of such simulation, thus reducing build failures and improving the results. In addition to offering state-of-the-art data preparation functionality to our users, our Magics product suite also focuses on automation and other productivity improvements and brings interconnectivity to machines and enterprise software platforms. Specific versions of the Magics application were also brought to the market by us, including Magics Essentials (an entry-level package offering premium data preparation functionality), Magics Print (combining the most important build preparation tools and straightforward build file generation technology) and MiniMagics/MiniMagicsPro (providing viewing, communication and quoting solutions for our customers working in data preparation, or in quoting and quality control teams). Users of Magics Essentials and Magics Print can upgrade to our expert Materialise Magics product suite if they want the full data and build preparation functionality at their disposal in one package. ● CO-AM. CO-AM is an additive workflow and digital manufacturing software platform designed as an open and collaborative ecosystem that supports customers in major manufacturing industries and large AM service bureaus to scale and integrate their additive manufacturing operations across complex supply chains and IT environments. At the core of the CO-AM platform is the customers’ project data. It brings together Materialise’s own applications and third party partner solutions, enabling customers to build a tailored environment that evolves with their needs. The CO-AM platform provides a series of applications that are instrumental to organizations scaling their additive manufacturing capability. These solutions enable organizations to plan, manage, and optimize their operations. The platform includes centralized order management, quoting and costing, production planning, production scheduling, postproduction management, machine connectivity, quality management and manufacturing analytics. ● Streamics. Streamics is our legacy 3D Print planning system that we consider as the predecessor of the CO-AM platform. We are gradually migrating Streamics functionality to our CO-AM platform. Once the Streamics functionality is fully integrated in CO-AM, a transition plan will be set up to migrate existing Streamics customers to the Link3D platform over the coming years. In the meantime, we will continue to maintain and support Streamics and its customers. ● 3-matic. 3-matic is a versatile application that permits, among other things, design modification, design simplification, 3D texturing, re-meshing and forward engineering directly to standard additive manufacturing mesh files. Using Materialise consultancy services, targeted design automation solutions can be created for specific workflows. 36 Table of Contents ● Build Processors. We work in close collaboration with a wide variety of 3D printer OEMs to develop customized and integrated solutions for their additive manufacturing machines. Our build processors automatically translate the 3D model data into layer data to provide sliced geometry and can link the latter with the appropriate build parameters to feed the machine control software. Another key benefit of our build processors is that they allow for a two-way communication between Magics and 3D printers. We also develop the metal build processors in Materialise Bremen and as a consequence we are able to cover a wide range of metal 3D printers. Furthermore, licensing and integrating our build processor framework, companies such as Siemens and PTC can also leverage the extensive ecosystem of build processors we have developed together with OEMs. Over the past years, we have transformed the architecture of our build processor to a cloud-native solution. Next to the standard build flows, the architecture and the availability of a BP-SDK (Software Development Kit) also allows for custom fit-for-purpose build pipelines to be scripted, enabling companies and 3D printer machine vendors alike to adapt and optimize the behavior and output of the build processor. This BP-SDK is available for customers to build their own build pipelines whilst having the possibility to integrate their proprietary IP in these pipelines. We believe this is very valuable in the context of volume production. ● e-Stage. e-Stage is a software solution that increases additive manufacturing productivity by automating support generation, optimizing the build process, and reducing the time our customers spend on finishing work such as build support removal and sanding. e-Stage is designed to allow our customers to use less material, to be able to 3D nest and to minimize failed builds. e-Stage for plastic has been commercially available since September 2007, and in the fall of 2017, we released e-Stage for metal. ● Identify3D. Identify3D is a suite of products that plugs into CO-AM and that allows customers to secure datasets throughout the full end-to-end process of 3D printing. Securing the data means adding a digital rights management tool on top of the part data, which protects the geometrical information of the data, but can be extended as well with process information (e.g., the number of times a file can be printed or the exact specifications how the file must be printed). Data security is gaining importance both because an increasing number of components are serially produced through additive manufacturing as well as with the growing importance of decentralized additive manufacturing production. ● Layer Analysis. Layer Analysis is a Machine Learning (ML) based tool that interprets images taken during the print of parts and looks for anomalies during the printing process. The tool combines the ML identified anomaly volumes with the to-be 3D files, allowing users to detect immediately after finishing a print if certain printed parts may show defects. In this way, unnecessary and expensive post-processing and (non-destructive) quality control can be avoided while it helps customers as well in defining allowable defects that do not affect the eventual part quality. Sales and Marketing. We market and distribute our software directly through our sales force as well as through our own website and third party distributors. Our Belgian team oversees our global marketing strategy and sales processes. Our local field office employees manage sales for particular markets and provide pre- and post-sales technical support to our customers. We also utilize a growing network of distributors and resellers to bring our solutions to specific regions or market segments. In addition, machine manufacturers and their local dealers often distribute our software products together with their 3D printers, with our software enhancing the printers’ value proposition and broadening the suite of applications available to the machines. Customers. The customers for our Materialise Software segment include 3D printing machine manufacturers as well as production companies and contract manufacturers in a variety of industries, such as the automotive, aerospace, consumer goods and hearing aid industries, and external 3D printing service bureaus. Our Materialise Software segment customer base is spread across Asia, Europe and the Americas. Competition. In our Materialise Software segment, we face indirect competition from the software developed by 3D printing OEMs, which are often more “closed ecosystem”-oriented (i.e., only focused on their own machines), and from companies that offer software that addresses one or more specific functional areas covered by our software solutions, such as providers of traditional CAD solutions. We compete directly with other providers of additive manufacturing management and machine control software, including open source software providers. Growth Opportunities. We believe that 3D printing will be increasingly used for the manufacturing of complex or customized end use parts, and expect that the number of 3D printer manufacturers will increase accordingly, with certain new players initially focusing more on the hardware than on the software component of their 3D printers. Hence, we anticipate that the demand for highly performing industrial 3D printing software platforms will grow accordingly. The new products that we have developed and are developing, including the CO-AM platform, Process Tuner, Workflow Automation and fit-for-purpose build processors specifically address what we believe will be the needs of this growing end use part manufacturing market. 37 Table of Contents We believe that expanding our market penetration involves strengthening our relationships with our customers and partners. This expansion will depend not only on product innovation and investments in tool development, but it will also involve an innovation of our business model. While we aim to address new groups of machine OEMs and customers, it is important to note that not all of them may adapt to our new solutions. Furthermore, as we transition to a modular approach in offering different configurations of our solutions, there could be short-term impacts on revenues. Unlike in previous years, our strategy for 2026 does not include expanding our marketing and sales presence. Instead, we have restructured our sales team in 2024 to support a shift from pure product sales to solution-oriented selling. This transition, though promising, carries risks, as it may take longer than anticipated for the sales teams to fully adapt. Currently, we are investing in the professional services team to better support our customers, but we are not expanding our marketing and sales presence overall. As we sell more platform solutions, integrate pre-print functionality into CO-AM as a cloud-native component, and launch our algorithms for use by OEMs and partners, our revenue models may evolve. While this shift presents opportunities, it also introduces risks. A key concern is that our transition to new business models, go-to-market strategies, and solution-based sales may not resonate with customers or could inadvertently cannibalize aspects of our core business revenue. Our Materialise Medical Segment In our Materialise Medical segment, our product and services offering addresses what we believe to be long-term trends in the medical industry towards personalized, functional and evidence-based medicine. As of December 31, 2025, our Materialise Medical segment consisted of approximately 1,134 FTEs and fully dedicated consultants, with approximately 21% based at our headquarters in Belgium and the remaining employees distributed throughout our local offices in Australia, Brazil, China, Colombia, France, Germany, Japan, Malaysia, South Korea, Ukraine, the United Kingdom and the United States. Business Model. We generate revenue in our Materialise Medical segment through the sale of medical software and personalized medical devices.

Materialise OrthoView currently serves more than 15,000 orthopedic surgeons in 60 countries globally, focusing primarily on joint replacements. We acquired OrthoView Holdings Limited in October 2014 (and subsequently dissolved this subsidiary in March 2025), and have included the OrthoView solution in our portfolio of pre-operative planning solutions. Clinical Services and Personalized Medical Devices. Using our FDA-cleared and CE compliant medical software, we analyze 3D medical images of patients and provide doctors with virtual surgical planning and simulation services for their review and approval. We also design and 3D print surgical guides that uniquely fit a specific patient and allow the surgeon to conduct the operation in accordance with the approved surgical plan. In certain circumstances, we deliver 3D printed customized patient-specific medical implants. In our 3D printing centers in Belgium, Japan, Brazil, and the United States, we have separate production lines for our Materialise Medical segment. We believe that our medical image-based simulation and planning software and 3D printing technology can assist hospitals and clinicians in providing personalized care to patients which can contribute to increased quality of life. In many cases, surgeons using our clinical services work together with our clinical engineers to turn their patients’ medical image data into virtual surgical plans, and patient-specific 3D printed precise surgical and customized anatomical models to optimize intervention planning. For indications such as shoulder surgery, we have optimized and automated our 3D planning capabilities to provide surgical plans within a short timeframe and at a high quality that does not require an anatomical model to be provided. Utilizing our platform, surgeons upload CT or MRI medical image data and submit their cases to us, track their cases and review them as interactive virtual 3D models. In the framework of our collaborations with certain leading medical device companies, our platform is rebranded and adapted to the specific product offering and needs of our collaboration partners. In many cases surgeons use personalized surgical guides or implants to translate the surgical plan into the operating room. Our 3D printed surgical guides include joint replacement guides for knee, shoulder and hip replacement surgeries, osteotomy guides and CMF guides, and our 3D printed implants include hip-revision implants, shoulder and CMF implants. The surgical guides and implants we print for U.S. based patients are FDA-cleared, and to the extent required by law, our medical devices for EEA-based patients bear the appropriate CE labels. 39 Table of Contents We address large surgical and interventional markets in orthopedics, CMF and cardiovascular through collaboration agreements with leading medical device companies, including DePuy Synthes, Zimmer Biomet, Enovis, Abbot, Medtronic and Smith & Nephew. Pursuant to these agreements, we provide planning services, print joint replacement and/or guides that our collaboration partners distribute under their own brands, together with their own implants, in the United States, Canada, South Africa, Latin America, Europe, China, Japan and Australia. We leverage our collaboration partners’ distribution capabilities to extend our reach into these large markets, and our collaboration partners utilize our 3D printing-related expertise to provide surgical planning and customized devices to surgeons. We also address certain high value-added, specialty applications by providing the full solution ourselves, including the delivery of planning and simulation services, implants and guides directly to the hospital or surgeon. Such applications include customized structural heart planning, CMF implants and guides, hip revision and shoulder implants in a patented porous matrix configuration and osteotomy guides.

In addition, we grant licenses to collaboration partners to use, market and distribute such software or surgical guides and implants. Some of the licenses we have granted to our products and software provide for exclusive rights, including with respect to a particular field of medicine or to the software or product developed during the collaboration, and certain collaboration partners may have rights of first refusal with respect to related products or collaborations. The compensation structures under these arrangements vary and may include an upfront fee, royalties, milestone payments linked to certain targets, and fees for the service, maintenance and training we provide in connection with our software and products. Competition. In our Materialise Medical segment, we compete with a number of companies that provide image based software, 3D printed surgical models or medical devices, such as 3DSystems, Stratasys, Simpleware and Pie Medical as well as with medical device companies that develop and commercialize 3D printed medical devices and related software services. Growth Opportunities. The Materialise Medical segment is the market where we believe we can most directly realize our mission statement and contribute to a healthier world. We believe that personalized surgical approaches, because they offer the potential of higher predictability and accuracy, lead to improved patient outcomes, fewer complications and increased long-term survival rates. Personalization also drives operational efficiencies by replacing a broad range of instrumentation with tailored versions. This makes surgery more efficient, but also lowers the cost of operational steps like sterilization. Personalized surgical approaches have benefits not only in complex interventions and we believe that personalized solutions will therefore see an increased adoption in the future. As a result, we are currently investing significantly in the development of new product offerings and the optimization of existing offerings in terms of cost and lead times, as well as in the expansion of our distribution channel in the various sub-segments of our Materialise Medical segment and in new territories. 40 Table of Contents As a result of the trend that we see in the medical community towards more patient-specific devices and treatments, as well as towards more advanced planning, a growing number of academic, clinical and commercial researchers are focusing on personalized medical treatments. Because these new products and treatments can only be brought to the market in compliance with very strict regulatory requirements, we believe there is an opportunity for safe and stable medical software tools, such as our Materialise Mimics, that can pass significant regulatory scrutiny. We also believe that increasing regulatory requirements provide opportunities for our clinical services as we can leverage our significant medical sector experience and strong quality management systems. A growing number of hospitals have adopted personalized solutions and built 3D printing facilities on site for point-of-care printing of these personalized solutions. We believe that there is a growing opportunity to provide our clinical services as well as our software solutions and experience in establishing operations to design personalized solutions in compliance with regulatory requirements. We are investing significantly in the development of new solutions of sub-markets other than orthopedics and CMF, including planning tools for the cardiovascular markets and the respiratory markets. Our Materialise Manufacturing Segment In our Materialise Manufacturing segment, we primarily offer 3D printing services to industrial customers, the majority of which are located in Europe. In addition, we have identified, and provide 3D printing services to certain specialty growth markets.

In addition, employees at our Belgian headquarters and in our local field offices manage sales for particular markets and accounts and provide back office and production management support to our customers. For our specialty markets and wearables initiatives we have separate sales teams that offer our customers the necessary expertise in their domain. Our sales teams have a direct approach to the market but in some cases we also work with partners or distributors locally to address specific market segments, such as the large segments of eyewear opticians or footcare professionals. Customers. The customers for our Materialise Manufacturing segment are from a wide variety of industries, including the automotive, aerospace, medtech, semiconductor, industrial goods, art and design and consumer products industries. For these customers, we offer a complete set of services ranging from design and engineering, to rapid prototyping, and certified manufacturing of end-use parts. Through our design and engineering service, we also service those customers looking for support in their initial concept design or with maximizing a design for 3D printing. Our design and engineering team, which is comprised of highly specialized designers and CAD engineers, offers dedicated design and software support for additive manufacturing, including remodeling and file preparation, as well as 3D scanning and measuring. Our team also offers training to engineering professionals active in various markets to accelerate the adoption of design for additive manufacturing. The customers of our Materialise OnSite platform order through our website. Materialise OnSite customers tend to be industrial customers looking to rapid prototype parts quickly and reliably, often taking advantage of fast-lane machines to ensure short lead times for time-critical projects. Most of our straightforward additive manufacturing and rapid prototyping solutions are executed on the basis of single transaction contracts or purchase orders with the customer. These contracts and purchase orders lay out the pricing, delivery and other terms of the order. For our Additive Manufacturing service of end-use parts, an entirely new approach to ensure parts are made according to agreed standards is required, for which we have set processes to onboard new customers. An example of this is our dedicated aerospace manufacturing line, backed by certifications EN9100 and EASA Part 21G, through which we are currently manufacturing plastic parts for, among others, Airbus’s A350 XWB. We expect that as demand for our Certified Additive Manufacturing service grows, we may enter into more long-term agreements with customers. 42 Table of Contents For the automotive manufacturers and their suppliers that use our RapidFit+ service, the fixtures are custom engineered by dedicated teams. Our RapidFit+ customers, which include their quality departments, expect that fixtures meet high accuracy standards. Several automotive OEMs in Europe are currently considering our innovative solution as a potential new standard, while a solid base of automotive Tier 1 suppliers in Europe has embraced RapidFit+ as one of their fixture solutions. Competition. In our additive manufacturing solutions business, we compete with a number of companies that provide industrial 3D printing services, including Sculpteo, Prototal, Protolabs and Quickparts. In addition, larger accounts tend to move their 3D printing production in-house once their orders have reached certain volumes, which not only creates opportunities for our Materialise Software segment but also for our Materialise Manufacturing segment in terms of capacity balancing services. In the measurement and quality control fixture market addressed by RapidFit+, we are not aware of any direct competition coming from 3D printing companies. We do have competition, however, from a large group of smaller companies that are active in the more traditional tooling manufacturing. Growth Opportunities. We believe that there is particular potential to grow our presence in the markets for additive manufacturing of complex and/or unique end products, including in particular certain parts for the aviation industry, medtech and eyewear and footwear products. In recent years, more companies have been using additive manufacturing for production across a broad range of industrial sectors, including aerospace, orthopedic implants, surgical guides, dental copings and hearing devices. For industrial end-use parts, we intend to continue to selectively invest in the expansion and creation of certified 3D manufacturing environments that meet the high standards of the specialized segments of the industrial production market that we focus on. In addition, we believe that our local sales teams, which are near our customers, as well as our engineering teams, which can bring in additional expertise where required, are important and rather unique assets in this market that are worthwhile to continue to invest in. Manufacture and Supply. We produce our 3D printed products at our service centers in Belgium, the Czech Republic, Germany, Poland, Japan, Brazil and the United States. We print substantially all of our products in-house using a variety of technologies, including stereolithography, laser sintering, FDM, PolyJet, Multi Jet Fusion, Powder Bed Fusion and vacuum casting, and only subcontracts the manufacture of products if certain other technologies (such as CNC machined components) are required or for capacity balancing purposes. As of December 31, 2025, we operated a total of 182 3D printers, five vacuum casting machines, and 28 CNC machines at these service centers. As of December 31, 2025, 56 printers produced parts exclusively for our Materialise Medical segment, while the other 126 printers and five vacuum casting machines produced parts for our Materialise Manufacturing segment. As of December 31, 2025, all of our 3D printers and vacuum casting machines were either owned or held under a lease contract. At the end of the lease agreements (which are typically for a period of five years), we have an option to purchase the machines for a value of approximately 1.0% of their original value. We are responsible for the maintenance of such leased equipment. We devote significant time and attention to the quality control of our products during the printing process by maintaining a comprehensive quality control program, which, among other things, includes the control and documentation of all material specifications, operating procedures, equipment maintenance and quality control methods. In addition, we inspect all of our raw materials to be used in our products throughout the printing process. We control our production orders through the use of labels or visual references on our internal database, bar-codes, controlled prints and routers, which enables us to trace our products during the printing process. Upon completion of the production process, we package and label our products. The raw materials used in the printing of our products are mainly aluminum, titanium alloy and stainless steel powders, epoxy based photocurable resins, PA12 and thermoplastic polyurethane, or TPU, based powders and a suite of thermoplastic filaments like ABS, PC and Ultem and quartz sand and furanic resin binder. With the exception of FDM, Stereolithography and PolyJet-materials, we believe that none of our other raw material requirements is limited to any significant extent by critical supply or price volatility. We continuously look for second sourcing of our raw materials in order not to be dependent on a single supplier in case a supply issue was to occur. We monitor the costs of our raw materials in order to optimize the cost/performance whilst not jeopardizing the expectations of our customers and the safe use of the materials in critical applications. 43 Table of Contents Our 3D printing operations for our patient-specific surgical guides, models and implants are subject to extensive regulation. We operate a certified quality management system in line with the U.S. Quality System Regulation, good manufacturing practice regulations and ISO 13485. We are registered with regulatory authorities in the United States, Europe, Canada, Australia and other jurisdictions. We CE mark our products where required. Our service centers are subject to periodic and sometimes unannounced inspections by regulatory authorities, including inspections by the FDA. Research and Development We have an ongoing research and development program to improve and expand the capabilities of our existing technology portfolio, which reflects our continued investments in a range of disciplines, including software development, industrial, mechanical and biomedical engineering. We have a long history of research and development through collaborations, which augment our internal development efforts. As of December 31, 2025, we were active in approximately 20 government funded research projects, which includes also the employment of multiple researchers with publicly funded scholarship. With our platform technologies and strong track record in successful commercialization of scientific innovations, we receive many requests for participation in new development projects. While we strongly protect our intellectual property in our core competencies, many of our products require collaborations in order to create healthy ecosystems for their successful implementation. As of December 31, 2025, we had more than 50 active research and development projects in various stages of completion and approximately 536 FTEs and fully dedicated consultants working on research and development in our facilities in Belgium, France, Germany, Spain, the United Kingdom, the United States, Colombia, Ukraine and Malaysia. Our research and development projects include (but are not limited to) the following: 1. various software development projects including projects related to engineering and design for 3D printing, and improving existing technological challenges (for example, the handling of large amounts of data and advanced image segmentation), which are expected to benefit both our Materialise Software and Materialise Medical segments; 2. research projects to understand and develop cutting-edge software tools for industrially relevant additive manufacturing technologies (powder bed fusion for plastics (laser sintering) and metal (laser melting and electron beam), stereolithography, FDM (also known as Filament Fusion), binder jetting power bed fusion, DLP-based printing and inkjet based technologies); 3. research projects in our Materialise Medical segment to develop patient specific surgical planning tools or surgical guides or implants for orthopedic, CMF and cardiovascular surgeries; 4. research projects on the use of virtual and augmented reality by our Materialise Medical segment; 5. research and development projects on smart digital technologies for the large-scale personalization of wearables; 6. various research projects on the use of artificial intelligence and (deep) machine learning in the fields of image processing and additive manufacturing; and 7. several research projects related to improving the maturity, reliability and quality of the additive manufacturing process, which are expected to benefit each of our three segments. We also regularly apply for research and development grants and subsidies under, among other, European, Belgian, British, French and German, grant rules. The majority of these grants and subsidies are non-refundable. We have received grants and subsidies from different authorities, including the Flemish government (VLAIO, or Vlaams Agentschap Innoveren en Ondernemen), the European Union (FP7 and H2020 framework programs) and BMBF, the German Federal Ministry of Education and Research. We expect to continue to invest significantly in research and development in the future. 44 Table of Contents Intellectual Property We regard our intellectual property rights as valuable to our business and protect our technology portfolio through a combination of patent, copyright, trademark, trade-secret and other intellectual property laws, confidentiality and other contractual provisions and other measures. The nature and extent of legal protection associated with each such intellectual property right depends on, among other things, the type of intellectual property right and the given jurisdiction in which such right arises. As of December 31, 2025, our portfolio of intellectual property featured 529 issued patents and an additional 128 pending patent applications primarily in the United States, the European Union and Japan. Of these, our issued patents expire between approximately 2028 and 2043, while our currently pending patent applications will generally remain in effect for 20 years from the date of the initial applications. We believe that, while our patents provide us with a competitive advantage, our success depends primarily on our business development, applications know-how and ongoing research and development efforts. Accordingly, we believe that the expiration of any single patent, or the failure of any single patent application to result in an issued patent, would not be material to our business or financial position. As is the case in the 3D printing industry generally, the development of our products, processes and materials has required considerable experience, manufacturing and processing know-how and research and development activities. We protect our proprietary products, processes and materials as trade secrets through nondisclosure and confidentiality agreements with our employees, consultants and customers. In addition, we own the trademark registrations for “Materialise”, “ACTech” and FEops and trademark registrations and pending applications for many of our services and software solutions in those territories where we have substantial sales, including “CO-AM,” “Mimics,” “3-matic,” “Inspector,” “Magics,” “RapidFit+,” “Heartprint,” “ADaM,” “Surgicase,” “Enlight,” “Streamics,” “Phits,” “HEARTguide,” “MITRALguide,” “TAVIguide,” among others. We are party to various licenses and other arrangements that allow us to practice and improve our technology under a broad range of patents, patent applications and other intellectual property, including agreements with our collaboration partners, Zimmer Biomet, Enovis, DePuy Synthes, Lima, Mathys, Stryker, Corin, Siemens, Fluidda, HOYA and PTC. There can be no assurance that the steps we take to protect our proprietary rights will be adequate or that third parties will not infringe or misappropriate such rights. We have been subject to claims and expect to be subject to legal proceedings and claims from time to time in the ordinary course of our business. In particular, we may face claims from third parties that we have infringed their patents, trademarks or other intellectual property rights. Such claims, even if not meritorious, could result in the expenditure of significant financial and managerial resources. Any unauthorized disclosure or use of our intellectual property could make it more expensive to do business and harm our operating results. Seasonality End markets such as healthcare, automotive, aerospace and consumer products may experience some seasonality. Historically, the revenue of our Materialise Software segment has been greater in the fourth quarter, as compared to the revenue of each of the other quarters. A number of our customers make their initial software purchase in the fourth quarter prior to the end of their annual budget cycle and tend to renew, extend or broaden the scope of their licenses on the anniversary date of their first purchase. In addition, we have in the past often brought new releases on the market in the third quarter of the calendar year, which may also have an impact on sales in the subsequent quarter. Regulatory / Environmental Matters Environmental Matters Our facilities and operations are subject to extensive U.S. federal, state and local, European and other applicable foreign environmental and occupational health and safety laws and regulations. These laws and regulations govern, among other things, air emissions; wastewater discharges; the generation, storage, handling, use and transportation of hazardous materials; the handling and disposal of hazardous wastes; the clean-up of contamination; and the health and safety of our employees. Under such laws and regulations, we are required to obtain permits from governmental authorities for some of our operations. If we violate or fail to comply with these laws, regulations or permits, we could be fined or otherwise sanctioned by regulators. We could also be held responsible for costs and damages arising from any contamination at our past or present facilities or at third party waste disposal sites. 45 Table of Contents Our headquarters in Belgium, our manufacturing sites in Czech Republic and Poland, and ACTech’s facility in Germany, have an effective environmental management system with ISO 14001:2015 certification. Compliance with laws and regulations relating to pollution of the environment or otherwise relating to the protection of the environment has not had a material impact on capital expenditures, earnings or the competitive position of our subsidiaries and us. We are not the subject of any legal or administrative proceedings relating to the environmental laws of Belgium or any country in which we have facilities. We have not received any notices of any violations of any such environmental laws. Healthcare Regulatory Matters In our Materialise Medical segment, we are subject to extensive and complex U.S. federal, state and local, European and other applicable foreign healthcare and medical devices laws and regulations. Both before and after approval or clearance our medical products and product candidates are subject to extensive regulation. In the United States, the FDA under the Federal Food, Drug and Cosmetic Act primarily regulates us. In Europe and in other foreign jurisdictions in which we sell our medical products, many of the regulations applicable to our medical devices and products in these countries are similar to those of the FDA. Together, these regulations govern, among other things and where applicable, the following activities in which we are involved: ● product development; ● product testing; ● product clinical trial compliance; ● product manufacturing; ● product labelling and instructions for use; ● product safety, product safety reporting, recalls and field corrective actions; ● product packaging and storage; ● product registration, market clearance or approval; ● product modifications; ● product marketing, advertising and promotion; ● product import and export, restrictions, tariff regulations, duties and tax requirements; ● product sales and distribution; ● post-market surveillance; ● record keeping procedures; ● registration for reimbursement; and ● necessity of testing performed in country by distributors for licenses. 46 Table of Contents Failure to comply with the Federal Food, Drug and Cosmetic Act could result in, among other things, warning letters, civil penalties, delays in approving or refusal to approve a medical device candidate, product recall, product seizure, interruption of production, operating restrictions, suspension or withdrawal of product approval, injunctions or criminal prosecution. Outside the United States, failure to comply with applicable laws and regulations could result in similar actions, and in the suspension or withdrawal of Quality Management System certification which may be a prerequisite to market medical devices. The time required to obtain clearance required by foreign countries may be longer or shorter than that required for FDA clearance, and requirements for licensing a product in a foreign country may differ significantly from FDA requirements. Moreover, these laws and regulations are subject to change. For example, on May 26, 2021, the Medical Devices Regulation became applicable in the European Union and replaced the Medical Device Directive. This transition required us to adopt a series of measures to ensure compliance. We have completed the transition to MDR and obtained EU MDR certification for our current portfolio of devices. Achieving certification required substantial updates to our quality management systems, technical documentation procedures, and post‑market surveillance processes. Additionally, we have secured extension letters for our existing EU Medical Device Directive certificates, allowing us to market these devices until at least 2027. While this reduces certain near‑term compliance risks and secures our ability to market MDR‑certified products in the EU, our certifications are subject to ongoing regulatory oversight. The MDR framework requires continued periodic audits, vigilance reporting, and maintenance of technical documentation. Failure to maintain compliance at any point could result in suspension or withdrawal of certifications. For more information, see “Item 3. Key Information—D. Risk Factors—Risks Related to Our Materialise Medical Segment and Regulatory Environment—Healthcare policy changes, including legislation to reform the U.S. healthcare system, could adversely affect us.” We maintain Medical Device Single Audit Program (MDSAP) certification. This program allows an MDSAP-recognized auditing organization to conduct a single regulatory audit of a medical device manufacturer that satisfies the relevant requirements of the regulatory authorities participating in the program. To the extent that we do business in the participating jurisdictions, certain major non-conformities identified under this program may be escalated to the regulatory authorities of the United States, Canada, Japan, Australia and Brazil. The Canadian regulatory authority, Health Canada, has made participation in MDSAP a mandatory requirement for medical device manufacturers importing products to Canada. Failure to maintain certification under MDSAP may impact our capability to do business in Canada. In addition, failure to address escalated issues reported to the participating authorities may impact our capability to do business in the respective jurisdictions. 47 Table of Contents C.

This section contains forward-looking statements that involve risks and uncertainties. Our actual results could differ materially from those contained in forward-looking statements. Factors that could cause or contribute to such differences include, without limitation, those discussed in the sections entitled “Item 3. Key Information—D. Risk Factors,” “Special Note Regarding Forward-Looking Information” and “Item 4. Information on the Company—B. Business Overview” and elsewhere in this annual report. A. Operating Results Overview Company Overview We are a leading provider of additive manufacturing and medical software tools and of sophisticated 3D printing services. With our knowledge, products and services, we empower our customers to use additive manufacturing technology more effectively, in general, and we enable certain specific and significant applications of additive manufacturing, in particular. In both instances, we seek to empower the choice for sustainability through the use of additive manufacturing. The customers of our general software tools and 3D printing services are active in a wide variety of industries, including healthcare, automotive, aerospace, art and design and consumer products. The significant additive manufacturing applications that we are more deeply and more directly involved in currently include applications for orthopedic, cranio maxillo facial, eyewear, footwear and measurement fixtures. As of December 31, 2025, our team consisted of 2,556 FTEs and fully dedicated consultants. Our portfolio of intellectual property featured 529 issued patents and 128 pending patent applications as of December 31, 2025. For the year ended December 31, 2025, we generated € 267.6 million of revenue, representing 0.3% increase over the prior year, a net profit of € 7.7 million, an Adjusted EBIT of € 10.6 million and an Adjusted EBITDA of € 32.4 million. For a description of Adjusted EBIT, Adjusted EBITDA and a reconciliation of our net profit to our Adjusted EBIT and Adjusted EBITDA, see “—Other Financial Information” below. Growth Strategy Our growth strategy is guided by the overall mission to strengthen our market position in additive manufacturing while expanding into areas with high long‑term potential. Within this company-wide vision, each of our segments develops its own shorter‑term strategy. The following describes how these strategies are applied in each of our three business segments. In our Materialise Medical segment, we believe that the growing trend of personalized patient care will boost the demand for digital planning tools as well as for personalized medical devices. In response to that trend, we intend to continue to increase the penetration of our existing software products in the hospital market and to expand our portfolio of planning tools into new areas such as cardiovascular and pulmonology. We also intend to continue to develop and grow the sales of our personalized medical device portfolio, both directly and indirectly and in existing as well as in new markets, including in particular in the CMF and the orthopedics markets. In our Materialise Software segment, we intend to strengthen the market penetration of our software platform by (i) continuing to gradually grow the strong position of our Magics 3D Print Suite in the market for print preparation software tools, including by offering its functionality through the cloud, and (ii) bringing our CO-AM platform to the market, offering to our customers both proprietary and third party functionalities that focus on volume production, including manufacturing execution systems, or MES, automated workflows for additive manufacturing and solutions such as quality analysis tools and data security. The transition to a cloud-based software platform and associated subscription models will affect our revenue levels in the near term, but we believe it may ensure the continued strength of our business model going forward. Further, in order to be able to meet the demands that are associated with volume production, including mass customization, and to accelerate the development and roll out of our cloud-based software platform, where software as a service, big data technologies, and machine learning will be key drivers, we intend to continue to invest significantly in both research and development. 50 Table of Contents In our Materialise Manufacturing segment, we believe that there is significant growth potential in the markets for additive manufacturing of end-use products. We therefore intend to continue to invest in the expansion and creation of certified 3D manufacturing environments that meet the high standards of the specialized segments of the industrial market, including the aerospace and defense markets. In the footwear market, we will continue to invest in the development and commercial roll out of the pressure plate technology and related applications that we acquired from RS Scan and in the worldwide commercialization of our Phits customized 3D printed insoles. Importantly, our applications and solutions focus on empowering our customers’ and partners’ choice for sustainability. In the applications that we support, additive manufacturing has the potential to not only replace traditional manufacturing technologies, but also to enable the digitization of customer journeys and supply chains, to localize manufacturing, to reduce inventories and the use of raw materials and to make end customers’ solutions more durable through personalization. We believe that this focus on the choice for sustainability will position us for long term sustainable growth, even if this may imply that we forego short term growth opportunities that do not fit this vision. Recent Developments See Note 27 to our audited consolidated financial statements for disclosure of significant transactions and significant changes in our financial condition or results of operations that occurred subsequent to December 31, 2025. In addition, see “Trend Information” below. Key Income Statement Items Revenue Revenue is generated primarily by the sale of our software and 3D printed and complex manufactured products and services. In our Materialise Software segment, we generate revenues from software licenses, maintenance contracts and custom software development services and sales of Materialise Controller. In our Materialise Medical segment, we generate revenue through the sale of medical devices that we print or manufacture for our customers and from the sale of licenses on our medical software packages, software maintenance contracts and custom software development and engineering services. In our Materialise Manufacturing segment, we generate most of our revenue through the sale of parts that we print or produce for our customers. Software. Software revenue is comprised of perpetual and time-based licenses, maintenance revenue and software development service fees. Our software products are mainly licensed pursuant to one of two payment structures: (i) perpetual licenses, for which the customer pays an initial fee for a perpetual license and subsequently pays fees for maintenance under separate maintenance contracts, generally on an annual basis, or (ii) time-based licenses (generally annual licenses), for which the customer pays equal periodic fees to keep the license active. Perpetual licenses require the payment of fees for maintenance, technical support and product updates. Time-based licenses entitle the customer to corrective maintenance and product updates without additional charge. We generally recognize revenue from our time-based licenses and our maintenance revenue on a straight-line basis over the term of the applicable license or maintenance contracts. Our software revenue depends upon both incremental sales of software licenses to both new and existing customers and renewals of existing time-based licenses and maintenance contracts. Sales and renewals are also driven by our customers’ usage and budget cycle. Software development services are typically charged either on a time and materials basis or on a fixed fee basis. 3D printed products and services. 3D printed products revenue is derived from our network of 3D printing service centers. Our service centers not only utilize our 3D printing technology to print products but are also full-service operations that provide support and services such as pre-production collaboration prior to printing the product. Revenue from 3D printed products depends upon the volume of products that we print for our customers. Sales of these products are linked to the number of our 3D printing machines that are installed and active worldwide. We have dedicated teams and production lines for industrial applications and medical applications. All medical products require a highly regulated production environment. Whereas both segments use the same 3D printing technologies, the complex combination of our engineering and software solutions in connection with medical applications results in higher margins for our medical applications. 51 Table of Contents Production of limited runs of highly complex casted metal parts. Casted products revenue is derived from ACTech’s network, with its production unit in Freiberg, Germany. ACTech is utilizing casting technology, including 3D printing technology for mold making, and offers full-service project operations, including project and pre-production collaboration, and high-end complex finishing services. Cost of Sales Our cost of sales includes raw materials, external subcontracting services, labor costs, manufacturing overhead expenses, amortization and depreciation and reserves for inventory obsolescence. Our manufacturing overhead expenses include quality assurance, manufacturing engineering, material procurement, inventory control, facilities, equipment and information technology and operations supervision and management. Research and Development Expenses Our research and development activities primarily consist of engineering and research programs associated with our products under development as well as research and development activities associated with our core technologies and processes. Research and development expenses are primarily related to employee compensation, including salary, fringe benefits, share-based compensation and temporary employee expenses. We also incur expenses for software and materials, supplies, costs for facilities and equipment, depreciation, and outside design and outside research support. Development expenditures on an individual project are recognized as an intangible asset when we can demonstrate: ● the technical feasibility of completing the intangible asset so that the asset will be available for use or sale; ● the intention to complete and the ability to use or sell the asset; ● how the asset will generate future economic benefits; ● the availability of resources to complete the asset; and ● the ability to measure reliably the expenditure during development. We have determined that the conditions for recognizing internally generated intangible assets from proprietary software, guides and other product development activities are not met until shortly before the products are available for sale, unless either (i) we have strong evidence that the above criteria are met and a detailed business plan is available showing the asset will on a reasonable basis generate future economic benefits or (ii) the development is done based upon specific request of the customer, we have the intention to market the product to parties other than the customer, the development is subject to an agreement and the substance of the agreement is that the customer reimburses us for a significant portion of the development expenses incurred. As such, development expenditures not satisfying the above criteria and expenditures on the research phase of internal projects are recognized in the consolidated income statement as incurred. Sales and Marketing Expenses Our sales and marketing expenses primarily consist of employee compensation, including salary, fringe benefits and share-based compensation for our marketing, sales and business development functions. Other significant expenses include travel, depreciation, product demonstration samples, brochures, websites and trade show expenses. General and Administrative Expenses Our general and administrative expenses primarily consist of employee compensation, including salary, fringe benefits and share-based compensation for our executive, financial, human resources, information technology support and regulatory affairs and administrative functions. Other significant expenses include outside legal counsel, independent auditors and other outside consultants, insurance, facilities, depreciation and information technologies expenses. 52 Table of Contents Net Other Operating Income Net other operating income consists primarily of withholding tax exemptions for qualifying researchers, development and government grants, partial funding of research and development projects, currency exchange results on purchase and sales transactions the amortization of intangible assets from business combinations, write-off of trade receivables, impairment of goodwill and intangible assets, and revaluation income or costs from participations. Government grants are recognized when there is reasonable assurance that the grant will be received and all attached conditions will be complied with. When the grant relates to development costs or another expense, it is recognized as income over the grant period necessary to match the income on a systematic basis to the costs that it is intended to compensate. When the grant relates to the construction of buildings, it is recognized as income over the depreciation period of the related building. Such grants have been received from the federal and regional governments and from the European Union in the forms of grants linked to certain of its research and development programs, reduced payroll taxes and the financing of the construction of an office building in Leuven, Belgium and of the construction of a new production facility in Freiberg, Germany. Where retention of a government grant is related to assets or to income and dependent on the Company satisfying certain criteria, it is initially recognized as deferred income. When the criteria for retention have been satisfied, the deferred income balance is released to other operating income in the consolidated income statement on a systematic basis over the periods in which the entity recognizes as expenses the related costs for which the grants are intended to compensate. Government grants are recognized when there is reasonable assurance that the grant will be received and all attached conditions will be complied with. Financial Expenses Our financial expenses primarily include costs associated with currency exchange differences and with interest payments on our debt. Critical Accounting Policies and Accounting Estimates The preparation of our consolidated financial statements requires management to make judgments, estimates and assumptions that affect the reported amounts of revenue, expenses, assets and liabilities, and the accompanying disclosures. Uncertainty about these assumptions and estimates could result in outcomes that require a material adjustment to the carrying amount of assets or liabilities for future periods. On an ongoing basis, we evaluate our estimates, assumptions and judgments, including those related to revenue recognition, development expenses, share-based payment transactions, income taxes, impairment of goodwill, intangible assets and property, plant & equipment and business combinations. We based our assumptions and estimates on parameters available when the consolidated financial statements were prepared. Existing circumstances and assumptions about future developments, however, may change due to market changes or circumstances arising beyond our control. Such changes are reflected in the assumptions when they occur. Revenue Recognition Our revenue recognition policies require management to make significant estimates. Management analyzes various factors, including a review of specific transactions, historical experience, creditworthiness of customers and current market and economic conditions. Changes in judgments based upon these factors could impact the timing and amount of revenue and cost recognized and thus affects our results of operations and financial condition. The significant estimates and judgments relate to: ● assessing whether a performance obligation is distinct in a bundled sale(s) transaction; ● estimation of the variable considerations and the assessment of the revenue constraint limitation; ● estimation of the stand-alone selling prices for each distinct performance obligation; and ● the stage of completion of our custom development of software components for customers when revenues are satisfied over time. 53 Table of Contents We make significant judgments when performing the assessment of whether a performance obligation is distinct from the other performance obligations in a contract, i.e., whether the good or service has a benefit to the customer on its own or together with readily available resources and/or whether the good or service is highly interrelated or constitutes a significant input with another good or service provided, or whether it significantly modifies or tailors another good or service. Relevant judgments include the following: ● Whether the software license is distinct from the 3D printed guides – in most cases with contracts with collaborative partners in the Materialise Medical segment, the software license is combined with the manufacturing of the 3D printed guides as the software license has no benefit to the customer without the manufacturing services. We have also implemented a new “Plan Only” feature where the collaboration partners can benefit from a virtual plan produced with the software license without the manufacturing of any physical product. Such Plan Only features are recognized in revenue as a separate performance obligation based on the usage by the collaboration partner. ● Whether the development services are distinct from other performance obligations – in most cases, these performance obligations are distinct however for one contract with a collaboration partner in the Materialise Medical segment, the software license is combined with the license and the 3D printed guides as one “distinct” performance obligation. For the stand-alone selling prices, we use prices from price list or historical prices for similar transactions. However, in certain cases, such information may not be readily available, and in those cases, we estimate the stand-alone selling price based on a cost-plus mark-up or other estimate. If the stand-alone selling price of one or more goods or services in arrangements with multiple performance obligations is highly variable or uncertain, we estimate the stand-alone selling price with reference to the total transaction price less the sum of the observable stand-alone selling prices of other goods or services promised in the contract. In addition, for certain performance obligations such as development services, the stand-alone selling prices also require an estimate of the time required to complete the development. Certain contracts include estimates of variable considerations within the transaction price and assessing the revenue constraint, such as: ● quantities/volume sold at fixed prices related to, but not limited to, the manufacturing of 3D printed products, software licenses sold and maintenance renewals; ● contractual prices may vary based on volume purchased during a given period; ● FTE expenses for development or other services billed on a time & material basis; and ● volume rebates. The method used to estimate the variable consideration depends on the number of possible scenarios and the probability of each scenario. If there are many possible scenarios with a high probability probabilities (each less than 50)%, we will use the expected value method, while the most likely method is used when there is a scenario with a higher probability (more than 50)%. Variable consideration is not a constraint when, based on historical experience, a high reliable business forecast and/or the timeframe of the estimates, we determine that there is a high probability that it will not result in a future reversal of revenue. We determine the stage of completion for development contracts satisfied over time by comparing the labor hours incurred to date with the estimated total labor hours required to complete the project. We consider labor hours to be the most reliable, available measure of progress on these projects. Adjustments to estimates to complete are made in the periods when facts that give rise to a change become known. When the estimate indicates that a loss will be incurred, the loss is recorded in the relevant period. Significant judgments and estimates are involved in determining the percentage completion for each contract. Different assumptions can produce materially different results. 54 Table of Contents Development Expenses Under International Accounting Standards 38, or IAS 38, internally generated intangible assets from the development phase are recognized if certain conditions are met. These conditions include the technical feasibility, the intention to complete, the ability to use or sell the asset under development, the availability of technical, financial and other resources to complete the asset, and the demonstration of how the asset will generate probable future economic benefits. The cost of a recognized internally generated intangible asset comprises all directly attributable cost necessary to make the asset capable of being used as intended by management. In contrast, all expenditures arising from the research phase are expensed as incurred. Determining whether internally generated intangible assets from development are to be recognized as intangible assets requires significant judgment, particularly in determining whether the activities are considered research activities or development activities, whether the product enhancement is substantial, whether the completion of the asset is technically feasible considering a company-specific approach and the likelihood of future economic benefits from the sale or use. We have determined that the conditions for recognizing internally generated intangible assets from proprietary software, guide and other product development activities are not met until shortly before the products are available for sale, unless either (i) we have strong evidence that the above criteria are met and a detailed business plan is available showing that the asset will generate future economic benefits on a reasonable basis or (ii) the development is done based upon specific request of the customer, we have the intention to market the product also to other parties than the customer, the development is subject to an agreement and the substance of the agreement is that the customer reimburses us for a significant portion of the development expenses incurred. As such, development expenditures not satisfying the above criteria and expenditures on the research phase of internal projects are recognized in the consolidated income statement as incurred. This assessment is monitored on a regular basis. We have determined that the criteria for internally generated intangible assets were met for two projects in 2018: (1) the software development of a new planner for hospitals within the cardiovascular field and (2) the process to obtain FDA and E.U. approval for a 3D printed tracheal splint within the Materialise Medical segment. The first project was successfully completed in 2019. In 2021, we recognized an impairment of € 0.2 million as the business case no longer showed a positive result over the next 5 years. The main reason was a delay in revenue due to the ongoing COVID-19 pandemic. The second project obtained the Investigational Device Exemption, or IDE, approval from the FDA in the first quarter of 2024. Because the present value of the expected cash flows until 2030 remains negative we continue to report the R&D expenses related to this program in our income statement. In the year ended December 31, 2020 we determined that the criteria for internally generated intangible assets were met for certain subprojects related to our internal digital transformation program. With this program, we are investing in our IT landscape and upgrading and/or standardizing part of our digital core business. We have further invested in 2025, and will continue to invest in 2026 in state-of-the-art technology that is available on the market to upgrade our CRM, ERP and license management software. Together with this implementation, we will also upgrade and further develop those internal software programs that are closely related to 3D printing and the specific needs that arise from 3D printing. The integration of both standard and internal systems in the digital chain of Materialise is crucial and requires deep analysis, development and technical validation. It is expected that it will not only streamline our processes internally and help us reduce costs in maintenance in the short term, but it also will allow us to learn from this and commercialize this knowledge by making our software even easier to integrate with standard systems. This competitive advantage should become important in the coming years where 3D printing will be more and more integrated on the traditional manufacturing floor. As of December 31, 2025, we capitalized € 10.2 million as software and carried € 0.3 million as assets under construction in respect of those projects. In the year ended December 31, 2021 we determined that the criteria for internally generated intangible assets were met for our project on the transformation of the platform architecture to enable our software products to make the transition from desktop to (hybrid) cloud. As of December 31, 2021 we had capitalized K€975 in respect of this project. During 2022 we continued to invest in this project and added K€984 to the asset under construction. As of December 31, 2022, we recognized an impairment of K€672 in respect of this asset under construction, due to an overlap with the recently acquired Link3D technology and the fact that this Link3D technology was already in a more advanced stage. The remaining K€1,287 was transferred from assets under construction to software, and amortization on this asset started in 2022. 55 Table of Contents Share-Based Payment Transactions We measure the cost of equity-settled transactions with employees based on the fair value of the equity instruments at the date at which they are granted and measures the cost of cash-settled transactions based on the fair value of the equity instrument at the date of reporting. We have applied the Black-Scholes valuation model to estimate fair value. The use of this model requires management to make assumptions regarding the volatility and expected life of the equity instruments. The assumptions used to determine fair value for share-based payment transactions are disclosed in Note 14 to our consolidated financial statements and are estimated as follows: ● the dividend return is estimated by reference to the historical dividend payment. Currently, this is estimated to be zero as no dividends have been paid since inception; ● expected volatility is determined based on the average annualized volatility of our shares (until September 2016: of a number of quoted peers in the 3D printing industry and the volatility of our shares); ● estimated life of the warrant is determined to be until the first exercise period which is typically the month after vesting; and ● fair value of the shares is determined based on the share price of our ADSs on Nasdaq at the date of valuation. For the grants prior to the initial public offering, the fair value of the shares was estimated based on a discounted cash flow model with three-year cash flow projections and a multiple of EBITDA determined based on a number of quoted peers in the 3D printing industry. Income Taxes Deferred tax assets are recognized only to the extent that it is probable that taxable profit will be available against which the deductible temporary difference can be utilized. Significant management judgment is required to determine the amount of deferred tax assets that may be recognized, based on the probable timing and level of future taxable profits, together with future tax planning strategies. As of December 31, 2025, we had current and non-current receivables related to tax credits for an amount of € 6 million (2024: € 6 million; 2023: € 5 million). As of December 31, 2025, we had € 144 million (2024: € 119 million; 2023: € 92 million) of tax losses carried forward and Innovation Income Deduction, of which € 70 million related to Materialise NV (2024: € 56 million; 2023: € 47 million). These losses relate to Materialise NV and subsidiaries that have a history of losses, in countries where these losses do not expire and may not be used to offset taxable income elsewhere in our consolidated group. Under the Belgian Innovation Income Deduction system, companies can deduct up to 85% of their net innovation income from the taxable basis. With respect to the tax losses carried forward and Innovation Income Deduction carried forward, a deferred tax asset of € 1.3 million was recognized at December 31, 2025 (2024: € 0.0 million; 2023: € 0.1 million) for Materialise NV. We recognized a deferred tax asset of € 0.5 million for Materialise USA (2024: € 1.2 million; 2023: € 1.0 million) and a deferred tax asset of € 1.0 million for ACTech (2024: € 0.0 million; 2023: € 0.0 million). We have not recognized deferred tax assets on unused tax losses and Innovation Income Deduction totaling € 34 million as at December 31, 2025 (2024: € 29 million; 2023: € 22 million) given that it is not probable that sufficient positive taxable base will be available in the foreseeable future against which these tax losses and Innovation Income Deduction can be utilized. If all deferred tax assets related to unused tax losses carried forward and Innovation Income Deduction would meet the criteria for recognition, net result for the year would have improved by € 34 million in 2025 through a deferred tax benefit. This would represent the planned recovery of € 34 million of unused tax losses carried forward and Innovation Income Deduction in future periods. Further details on taxes are disclosed in Note 22.10 to our consolidated financial statements. 56 Table of Contents Impairment of Goodwill, Intangible Assets and Property, Plant and Equipment We have goodwill for a total amount of € 43.2 million as of December 31, 2025 (2024: € 43.4 million; 2023: € 43.2 million) which has been subject to an impairment test. Goodwill is tested for impairment based on a discounted cash flow model with cash flows for the next five years derived from the budget, and a residual value considering a perpetual growth rate. The value in use is sensitive to the discount rate used for the discounted cash flow model as well as the expected future cash-inflows and the growth rate used for extrapolation purposes. The key assumptions used to determine the value in use for the different cash generating units, or CGUs, are disclosed and further explained in Note 5 to our consolidated financial statements. When events or changes in circumstances indicate that the carrying amount of the intangible assets and property, plant and equipment may not be recoverable, we estimate the value in use for the individual assets, or when not possible, at the level of CGUs to which the individual assets belong. Total impairment charges recorded during 2025 were € 0.0 million (2024: € 0.0 million; 2023: € 4.2 million). In 2023, we recorded a goodwill impairment of € 4.2 million related to Materialise Motion and Engimplan. On the CGU Materialise Motion in Belgium, it was concluded that the value in use was lower than the carrying value, which resulted in a full impairment of the goodwill for an amount of € 1.2 million as well as a partial impairment on the intangible assets related to the partnership agreement, customer list, and developed technology for respectively € 0.9 million, € 0.1 million, and € 1.4 million. The key elements that led to the impairment loss for the Motion CGU was the delay in business growth versus what was initially foreseen. On the CGU Engimplan in Brazil, it was concluded that the value in use was lower than its carrying value, which resulted in a full impairment of the intangible assets related to customer list and trademarks for respectively € 0.4 million and € 0.1 million as well as a tangible asset 3D printer for € 0.1 million. The key elements that led to the impairment loss for the Engimplan CGU were related to a delay in business growth and to less benefits of synergies than initially anticipated. Business Combinations We determine and allocate the purchase price of an acquired business to the assets acquired and liabilities assumed as of the business combination date. The purchase price allocation process requires us to use significant estimates and assumptions, including: ● estimated fair value of the acquired intangible assets; ● estimated fair value of property, plant and equipment; and ● estimated fair value of the contingent consideration. The contingent consideration as included in the financial statements is recorded at fair value at the date of acquisition and is reviewed on a regular basis, at least annually. The fair value of the contingent consideration is based on risk-adjusted future cash flows of different scenarios discounted using appropriate interest rates. The structure of the possible scenarios and the probability assigned to each one of them is reassessed by management at every reporting period and requires judgement from management about the outcome and probability of the different scenarios as well as the evolution of the variables. While we are using our best estimates and assumptions as part of the purchase price allocation process to accurately value assets acquired and liabilities assumed at the date of acquisition, our estimates and assumptions are inherently uncertain and subject to refinement. Examples of critical estimates in valuing certain of the intangible assets we have acquired or may acquire in the future, include but are not limited to: ● future expected cash flows from customer contracts and relationships, software license sales and maintenance agreements; ● the fair value of the plant and equipment; ● the fair value of the deferred revenue; ● discount rates; and ● the technology royalty rate. 57 Table of Contents Provision for Expected Credit Losses, or ECLs, of Trade Receivables and Contract Assets We use a provision matrix to calculate ECLs for trade receivables and contract assets. The provision rates are based on days past due for groupings of various customer segments that have similar loss patterns (i.e., by legal entity). The provision matrix is initially based on our historical observed default rates. The matrix is calibrated to adjust the historical credit loss experience with forward-looking information. For example, if economic conditions (i.e., gross domestic product) are expected to deteriorate over the next year which can lead to an increased number of defaults, the historical default rates are adjusted. At each reporting date, the historical observed default rates are updated and changes in the forward-looking estimates are analyzed. The assessment of the correlation between historical observed default rates, expectations of economic conditions and ECLs is a significant estimate. The amount of ECLs is sensitive to changes in circumstances and of forecast economic conditions. Our historical credit loss experience and expectations of economic conditions may also not be representative of a customer’s actual default in the future. Information about the ECLs on our trade receivables and contract assets is disclosed in Note 25 to our consolidated financial statements. Convertible Loan Granted to Fluidda We accounted for the convertible loan granted to Fluidda in January 2019, with a notional amount of €2.5 million, at fair value until its full repayment in November 2025. The carrying value of the convertible loan amounted to €0.0 million at December 31, 2025 (2024: €4.0 million; 2023: € 3.8 million) following a full repayment, including all capitalized interests, by Fluidda in November 2025. Fluidda is a private start-up company which offers turnkey contract research services for drug development and medical device development. In prior periods, determining the fair value of the convertible loan, we considered different contractual parameters such as the repayment and conversion scenarios and dates. In addition, we made significant estimates such as (i) the discount rate, (ii) the probability and timing of each repayment and conversion scenario, and (iii) the amount of a qualified capital increase that determined the conversion factor. We applied a discount factor that was based on the estimated weighted average cost of capital of Fluidda, reflecting the uncertainty in relation to Fluidda’s ability to be successful and the applied estimates by our consolidated group. Leases – Estimating the Discount Rate and Probability of Exercising Extension Options/Termination Options and Purchase Options As we cannot always determine the interest rate implicit in lease contracts, we must estimate the incremental borrowing rate to measure certain lease liabilities such as buildings. For buildings, we use the property yield as a reference to determine the incremental borrowing rate. For other assets, we generally use the interest rate implicit in the lease contract or apply the incremental borrowing rate for a portfolio of similar assets. The incremental borrowing rate reflects what we “would have to pay”, which requires estimation when no observable rates are available or when they need to be adjusted to reflect the terms and conditions of the lease. In addition, certain lease contracts may have extension options, termination options (in the case of property leases) and/or purchase options (in the case of leases). We estimate whether it is reasonably certain that such options will be exercised, which impacts the lease term in the case of extension options and termination options and the period over which the lease assets are depreciated in the case of purchase options. Recent Accounting Pronouncements The standards and interpretations that are issued, but not yet effective, up to the date of issuance of our financial statements are disclosed in our financial statements included elsewhere in this annual report. 58 Table of Contents Results of Operations Comparison of Years Ended December 31, 2025 and 2024 For the year ended December 31, in 000€, except percentages 2025 2024 % Change Revenue 267,633 266,765 0.3 % Cost of sales (114,684) (115,940) (1.1) % Gross profit 152,949 150,826 1.4 % Research and development expenses (46,089) (44,400) 3.8 % Sales and marketing expenses (61,591) (61,620) (0.0) % General and administrative expenses (40,122) (39,597) 1.3 % Net other operating income 3,789 4,223 Operating profit 8,936 9,432 Financial expenses (5,616) (2,969) Financial income 3,968 7,677 Profit before taxes 7,287 14,139 Income taxes 429 (733) Net profit 7,716 13,406 Revenue. Revenue increased by € 0.9 million, or 0.3%, to € 267.6 million in the year ended December 31, 2025, from € 266.8 million in the year ended December 31, 2024. Revenue by geographical area is presented as follows: For the year ended December 31, in 000€ 2025 2024 Americas 117,131 115,100 Europe & Africa 131,170 133,588 Asia-Pacific 19,332 18,077 Total 267,633 266,765 Revenue generated in Europe & Africa decreased by € 2.4 million, or 1.8%, in the year ended December 31, 2025, compared to the year ended December 31, 2024, due to lower revenue from our Materialise Manufacturing segment and from our Materialise Software segment. This decline was partially offset by revenue growth in our Materialise Medical segment. Revenue generated throughout the Americas increased by € 2.0 million, or 1.8%, in the year ended December 31, 2025, compared to the year ended December 31, 2024, due to higher revenue from our Materialise Medical, which was offset by decline in our Materialise Manufacturing and Materialise Software segments. Revenue generated in Asia-Pacific increased by € 1.3 million, or 6.9% in the year ended December 31, 2025, compared to the year ended December 31, 2024, driven by revenue growth in our Materialise Medical and Materialise Manufacturing segments, while our Materialise Software segment declined compared to 2024. Revenue from our Materialise Medical segment increased € 17.9 million, or 15.4%, from € 116.4 million in the year ended December 31, 2024, to € 134.2 million in the year ended December 31, 2025. Within our medical software department recurrent revenue from annual and renewed licenses and maintenance fees increased by € 2.3 million, or 7.9%, reflecting the implementation of our continued strategy focused on products with defined contractual periods. These recurrent revenues represented 84.9% of all medical software revenues in the year ended December 31, 2025, compared to 85.0% in the year ended December 31, 2024. Our non-recurrent revenue from perpetual licenses and services decreased by 3.9% to € 4.4 million in the year ended December 31, 2025, compared to € 4.6 million in the year ended December 31, 2024. Deferred revenue from license and maintenance fees amounted to € 1.8 million in the year ended December 31, 2025, compared to € 1.8 million in the year ended December 31, 2024. Revenues from medical devices and services grew by € 15.1 million, or 18.4%, in the year ended December 31, 2025, driven by growth in all of our sales channels across our different core markets. As of December 31, 2025, our Materialise Medical segment operated 56 3D printers, as compared to 51 as of December 31, 2024. 59 Table of Contents Revenue from our Materialise Software segment decreased € 3.0 million, or 6.8%, from € 43.9 million in the year ended December 31, 2024, to € 40.9 million in the year ended December 31, 2025. Recurrent revenue, consisting of limited license fees and maintenance fees, increased by € 1.3 million, or 3.9%, in the year ended December 31, 2025. Non-recurrent revenue, mainly consisting of perpetual fees and services, decreased by € 4.2 million, or 36.6%, in the year ended December 31, 2025. Deferred revenue from license and maintenance fees amounted to € 0.1 million in the year ended December 31, 2025, compared to € 0.6 million in the year ended December 31, 2024. Revenue from our Materialise Manufacturing segment decreased € 14.0 million, or 13.2% mainly due to macro-economic headwinds, from € 106.5 million in the year ended December 31, 2024, to € 92.5 million in the year ended December 31, 2025. Materialise Manufacturing operated 126 3D printers, 28 CNC machines and 5 vacuum casting machines as of December 31, 2025, compared to 155 3D printers, 39 CNC machines and 5 vacuum casting machines as of December 31, 2024, respectively. Cost of sales. Cost of sales was € 114.7 million in the year ended December 31, 2025, compared to € 115.9 million in the year ended December 31, 2024, representing a decrease of € 1.3 million, or 1.1%. This decrease in cost of sales was related to decreased subcontracting volumes, offset by increased sales volumes, and the impact of inflation related to energy, materials and compensation expenses. Gross profit. Gross profit increased € 2.1 million from € 150.8 million in the year ended December 31, 2024, to € 152.9 million in the year ended December 31, 2025, mainly driven by increased total revenue, slightly offset by higher production costs. The overall gross profit margin (gross profit divided by our revenue) amounted to 57.1% in the year ended December 31, 2025, compared to 56.5% in the year ended December 31, 2024. Research and development, or R&D, sales and marketing, or S&M, and general and administrative, or G&A, expenses. R&D, S&M and G&A expenses increased, in the aggregate, to € 147.8 million in the year ended December 31, 2025, compared to € 145.6 million in the year ended December 31, 2024. R&D expenses increased from € 44.4 million to € 46.1 million, or 3.8%. S&M expenses remained stable at € 61.6 million. G&A expenses increased from € 39.6 million to € 40.1 million, or 1.3%, including € 0.8 million non-recurring expenses related to the Euronext Brussels listing of our ordinary shares in November 2025. Net other operating income. Net other operating income decreased to € 3.8 million, in the year ended December 31, 2025, compared to € 4.2 million in the year ended December 31, 2024. Net other operating income included gains on withholding tax exemptions of € 2.8 million, grants received of € 2.5 million, and R&D tax credits of € 0.9 million. These gains were partially offset by amortization expenses of acquired intangible assets, which represented an expense of € 3.1 million for the year ended December 31, 2025. Net other operating income included withholding tax exemptions of € 3.4 million, grants received of € 1.5 million, R&D tax credits of € 1.2 million, and an expense of € 3.3 million for the year ended December 31, 2024. Net financial income (financial income and financial expense). Net financial expense was € 1.6 million in the year ended December 31, 2025, compared to a net financial income of € 4.7 million in the year ended December 31, 2024. The net financial expense in 2025 was primarily attributable to a higher negative impact from unfavorable foreign exchange rate fluctuations. Income taxes. Income taxes in the year ended December 31, 2025 amounted to € 0.4 million, which was a combination of deferred tax benefits amounting to € 1.4 million and current income tax expenses of € 0.9 million. Net profit/loss. As a result of the factors described above, net profit amounted to € 7.7 million in the year ended December 31, 2025 compared to € 13.4 million in the year ended December 31, 2024. 60 Table of Contents Other Financial Information We use EBIT, EBITDA, Adjusted EBIT and Adjusted EBITDA as supplemental financial measures of our financial performance, including for purposes of monitoring compliance with financial covenants, supporting discussions with financing institutions, and meeting reporting requirements to our banks. 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 expenses related to business combinations or divestiture-related expenses, (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 our day-to-day operations. We also use segment Adjusted EBIT, segment Adjusted EBIT margin, segment Adjusted EBITDA, and segment Adjusted EBITDA margin to evaluate the performance of our 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 our 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 our 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. We believe that these measurements are useful to measure a company’s ability to grow or as a valuation measurement. Our calculation of EBIT, EBITDA, Adjusted EBIT and Adjusted EBITDA may not be comparable to similarly titled measures reported by other companies. Disclosure in this annual report of EBIT, EBITDA, Adjusted EBIT and Adjusted EBITDA, which are non-IFRS financial measures, is intended as a supplemental measure of our performance that is not required by, or presented in accordance with, IFRS.

Liquidity and Capital Resources Prior to our initial public offering, we historically funded our operations principally from cash generated from operations and borrowings. From our initial public offering on June 30, 2014 through December 31, 2025, we have raised approximately $258.5 million in aggregate net proceeds from public offerings of our ADSs and a private placement of our ordinary shares. As we continue to grow our business, we envision funding our operations through multiple sources, including the remaining proceeds from our equity offerings, and future earnings and cash flow from operations and borrowings. We may also seek to raise additional capital from offerings of our equity or debt securities on an opportunistic basis when we believe there are suitable opportunities for doing so. On November 20, 2025 the Group successfully completed an additional listing of its ordinary shares on Euronext Brussels to complement the existing Nasdaq listing of its American depositary shares (ADSs) representing ordinary shares. A listing on Euronext Brussels may give the company access to additional capital in the future if needed, and is intended to create additional liquidity options for shareholders of the Company. In addition, a listing on Euronext Brussels provides the Group with enhanced operational flexibility, including the option to initiate ADS and/or share buyback programs. No shares were offered and no capital was raised in connection with the Euronext Brussels listing. On November 14, 2025 the Company’s general shareholder’s meeting adopted a resolution authorizing the Board of Directors to initiate an ADS and/or share buy back program for a total amount of up to € 30.0 million. Repurchases were expected to be initiated by no later than January 2026 and executed within 12 months following initiation. The Company’s current intention is to hold any ADSs acquired (or underlying shares) in treasury. The Company may in the future use these as a consideration for mergers and acquisitions, and/or otherwise dispose of those ADSs or shares, including for potential share delivery commitments under future equity incentive plans. As of December 31, 2025, the Company had entered into an agreement with an independent US financial intermediary to execute ADS repurchases on Nasdaq for a total amount of up to the USD equivalent of € 30.0 million, but no actual transactions had taken place yet. For information regarding repurchase activity under our share buy back program subsequent to December 31, 2025, see Note 27 to our audited consolidated financial statements. We expect our main uses of cash in the future will be funding our business operations, capital expenditures, loan reimbursements, acquisitions and partnerships, and repurchases of ordinary shares and ADSs under our share buy back program. Depending on market conditions, our liquidity requirements, contractual restrictions and other factors, we may also repurchase additional outstanding ordinary shares and ADSs. We believe that we will have sufficient liquidity to satisfy the operating requirements of our business through the next 12 months. In 2022, we entered into a credit facility agreement with KBC, which allows for a €50 million delayed draw, that will allow funding of potential additional acquisitions, partnerships, and capital expenditures. The credit facility provides for a first draw of €20 million between October 2022 and April 2025, repayable in full in April 2030. The Company drew the first tranche in April 2025. A second draw of €15 million could be made between October 2022 and July 2025, repayable in full in June 2031. The Company drew the second tranche in July 2025. A third and final draw of €15 million may be made between October 2022 and July 2026, repayable in full in June 2032. Our liquidity plans are subject to a number of risks and uncertainties, including those described in the section of this annual report titled “Item 3. Key Information—D. Risk Factors,” some of which are outside of our control. Macro-economic conditions could hinder our business plans, which could, in turn, adversely affect our financing strategy.

Purchases of intangible assets are mostly related to our internal digital transformation program. Indebtedness As of December 31, 2025, we had loans and borrowings in the total amount of € 63.1 million, with mainly fixed interest rates. These loans include secured bank loans used for the construction of office and production facilities in Belgium and Poland, the acquisition of production equipment and installations, and research and development projects.

The contract contains customary security, covenants and undertakings. K€28,000 Acquisition loan This bank loan was concluded in October 2017 to finance the acquisition of ACTech. The loan included a portion of € 18.0 million, repayable monthly over five years, and a bullet portion of € 10.0 million, which was reimbursed at once in October 2024. The interest rate was fixed for the duration of the loan, and amounted to 1% on average for both portions.

Transfers from Subsidiaries The amount of dividends payable by our subsidiaries to us is subject to general limitations imposed by the corporate laws and certain restrictions in the jurisdictions that we operate in. For example, China has very specific approval regulations for all capital transfers to or from the country, certain capital transfers to and from Ukraine are subject to obtaining a specific permit and current legislation in Brazil permits the Brazilian government to impose temporary restrictions on remittances of foreign capital abroad in the event of a serious imbalance or an anticipated serious imbalance in Brazil’s balance of payments. Dividends paid to us by certain of our subsidiaries may also be subject to withholding taxes in certain jurisdictions. Of our cash and cash equivalents held outside of Belgium as of December 31, 2025, 2024 and 2023, the amount of cash that would have been subject to withholding taxes if transferred to us by way of dividends and the amount of cash that could not have been transferred by law, or the transfer of which would have been subject to prior approval that was beyond our control, was in each case immaterial. 71 Table of Contents Contractual Obligations Our contractual commitments will have an impact on our future liquidity.

No interest is payable on the other contractual obligations in the above table. As of December 31, 2025 we had purchase commitments of K€467 (2024: K€5,370; 2023: K€9,330) related to property, plant and equipment and non-cancellable contracts with a future value of K€19,008 (2024: K€24,237; 2023: K€22,267) mainly related to purchase commitments for raw materials, energy and gas. C. Research and Development, Patents and Licenses For information regarding our research and development program, see “Item 4. Information on the Company—B. Business Overview—Research and Development.” D. Trend Information Impact of the armed conflict in Ukraine As discussed in more detail in “Item 3. Key Information—D. Risk Factors” of this annual report, we have an office in Kyiv, employing over 400 collaborators who are mainly engaged in engineering, software development and supporting IT and staff functions. As a result of the armed conflict in Ukraine, our operations from our Kyiv office operate in very difficult, uncertain and unstable circumstances. To-date, most of our personnel from the office in Kyiv have continued to work for us throughout the armed conflict, either remotely from Ukraine or other neighboring countries, from our Wroclaw office or, circumstances permitting, from our office in Kyiv, while others remain unable to perform their work. As of the date of this annual report, we have been able to continue servicing our customers without significant disruption or delay, as personnel with similar skills and competencies located elsewhere in the world have increased their roles and responsibilities to assist displaced personnel. As the armed conflict with Russia continues, it is impossible to predict how much of our Ukrainian workforce will be able or willing to continue working for us. As we are unable to predict how the armed conflict in Ukraine will evolve, we cannot exclude that delays or disruption in certain of our services may occur or that a more radical, temporary shift of certain operations to other jurisdictions may become necessary, which could impact our business and operations, results of operations, financial condition, cash flows and liquidity. We have incurred, and will continue to incur, expenses related to hiring additional and more expensive resources outside Ukraine. It is uncertain to what extent some of the development projects of our Materialise Software and Materialise Medical segments, and to a lesser extent our Materialise Manufacturing segment, will be impacted by the ongoing armed conflict in Ukraine. As a result of such impact, some of our anticipated product releases may be delayed, which may adversely affect our revenue. As of the date of this annual report, we are unable to predict how the armed conflict in Ukraine will evolve or what the impact of any political and direct and indirect economic repercussions will be on the global economy and our business. Indirect economic repercussions could, for example, come from continued or further increased inflation, or currencies instability. As a result, we are unable to assess with certainty its impact on our business and operations, results of operations, financial condition, cash flows and liquidity. 72 Table of Contents E. Critical Accounting Estimates For information regarding our critical accounting estimates, see “—Operating Results—Critical Accounting Policies and Accounting Estimates” above. Off-Balance Sheet Arrangements We do not have any off-balance sheet arrangements that have, or are reasonably likely to have, a current or future effect on our financial condition, changes in financial condition, revenues or expenses, results of operations, liquidity, capital expenditures or capital resources that is material to investors.
