Risk Factors Summary of Risk Factors Risks Relating to Our Business ● We may not be able to maintain or increase the market share or reputation of our software and other products and services that they need to remain or become a market standard. ● We may not be successful in continuing to enhance and adapt our software, products and services in line with developments in market technologies and demands. ● 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. ● Existing and increased competition may reduce our revenue and profits. ● We rely on collaborations with users of our additive manufacturing and related solutions to be present in certain large-scale markets and, indirectly, to expand into potentially high-growth specialty markets. Our inability to continue to develop or maintain these relationships in the future could harm our ability to remain competitive in existing markets and expand into other markets. ● Our revenue and results of operations may fluctuate. ● Inflation has had and may continue to have an adverse effect on our results. ● Demand for additive manufacturing generally and our additive manufacturing software solutions, products and services in particular may not increase adequately, or at all. ● We are dependent upon sales to certain industries. ● If our relationships with suppliers, including with limited source suppliers of consumables, were to terminate or our manufacturing arrangements were to be disrupted, our business could be adversely affected. 3 Table of Contents ● The dominant software subscription model in the industrial sector is changing, and we may not be successful in developing a cloud-based platform to offer our software. ● We may not be able to successfully adopt our software offering to the changing needs of the additive manufacturing market. ● 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. ● We may need to raise additional capital from time to time in order to meet our growth strategy and may be unable to do so on attractive terms, or at all. ● 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. ● Our international operations pose currency risks, which may adversely affect our results of operations and net income. ● Our international operations subject us to various risks, and our failure to manage these risks could adversely affect our results of operations. ● We may engage in acquisitions or investments that could disrupt our business, cause dilution to our shareholders and harm our financial condition and results of operations. ● We may enter into collaborations, in-licensing arrangements, joint ventures, strategic alliances or partnerships with third parties that may not result in the development of commercially viable products or the generation of significant future revenue. ● Failure to comply with applicable anti-corruption and trade sanctions legislation could result in fines, criminal penalties and an adverse effect on our business. ● 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. ● We rely on our information technology systems to manage numerous aspects of our business and customer and supplier relationships, and a disruption of these systems could adversely affect our results of operations. ● A breach of security in our products or computer systems may compromise the integrity of our products, harm our reputation, create additional liability and adversely impact our financial results. ● If our 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. Risks Related 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. Risks Related to Our Intellectual Property ● If we are unable to obtain patent protection for our products or otherwise protect our intellectual property rights, our business could suffer. ● We cannot predict the outcome of an arbitration proceeding in which we are involved. 4 Table of Contents Risks Related to the American Depositary Shares (ADSs) ● 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. Risks Relating to Our Business We may not be able to maintain or increase the market share or reputation of our software and other products and services that they need to remain or become a market standard. The additive manufacturing, or 3D printing, industry is rapidly growing 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. We may not be successful in continuing to enhance and adapt our software, products and services in line with developments in market technologies and demands. Our present or future software, products and services 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, product and services to developments in technologies and to new and changing customer needs (in particular in relation to the manufacturing of end parts and the offering of cloud-based software solutions). We believe that to remain competitive we must continuously enhance and expand the functionality and features of our products, services and technologies. However, there can be no assurance that we will be able to: ● maintain and enhance the market share of our current products, services and technologies; ● enhance our existing products, services and technologies; ● develop new products, services and technologies that address the increasingly sophisticated and varied needs of prospective end-users (including in the emerging market of using additive manufacturing for end parts instead of prototypes and the trend of offering more cloud-enabled software solutions); ● respond to technological advances and emerging industry standards and practices on a cost-effective and timely basis; ● adequately protect our intellectual property as we develop new products, services and technologies and anticipate intellectual property claims from third parties; or ● continue to integrate the product portfolio of Link3D and Identify3D into our own product portfolio. 5 Table of Contents 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 can be no assurances, however, that these research and development programs will improve our existing additive manufacturing software solutions, products and services or create new software, products or services. 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. Existing and increased competition may reduce our revenue and profits. 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. In particular, 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 can 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, or CAD, or computer-aided manufacturing, or 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. 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. In addition, competitors with more efficient or profitable business models, superior techniques or more advanced technologies may take market share away from us. Also, in certain specific markets that our Materialise Manufacturing segment targets, including, among others, the shoe wear, eyewear and fixtures markets, established players may develop their own competitive solutions or may engage in collaborations with competitors of ours, 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. 6 Table of Contents We rely on collaborations with users of our additive manufacturing and related solutions to be present in certain large-scale markets and, indirectly, to expand into potentially high-growth specialty markets. Our inability to continue to develop or maintain these relationships in the future could harm our ability to remain competitive in existing markets and expand into other markets. 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 group as Enovis), Smith & Nephew Inc., or Smith & Nephew, Corin Ltd, or Corin, Medtronic Inc., or Medtronic, and Abbott Laboratories Inc., or Abbott. 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. In addition, a change of control of any of our collaboration partners may negatively impact our relationship. If we are not able to maintain our existing collaborations and develop new collaborative relationships, our foothold in larger markets and expansion into potentially high-growth specialty markets could be harmed significantly. Our revenue and results of operations may fluctuate. Our revenue and results of operations may fluctuate from quarter-to-quarter and year-to-year and are likely to continue to vary due to a number of factors, many of which are not within our control. You should not rely on our past results as an indication of our future performance. Fluctuations in our results of operations and financial condition may occur due to a number of factors, including, but not limited to, those listed below and those identified throughout this annual report: ● our ability to continue, renew or replace relationships with key customers; ● the degree of market acceptance of our software and our products; ● the mix of software, products and services that we sell during any period, as well as the mix of the various markets in which we make sales during said periods; ● a decline in new or renewed periodic licenses or maintenance contracts; ● delays in the introduction of new features; ● the entry of new competitors into our market; ● the development and degree of market acceptance of new competitive systems or processes by others; ● changes in our pricing policies or those of our competitors, including our responses to price competition; ● changes in the amount we spend in our marketing and other efforts; ● delays between our expenditures to develop, acquire or license new technologies and processes, and the generation of sales related thereto; ● the amounts we spend on, and the success rate of, our research and development activities; ● changes in the regulatory environment, including changes in regulatory laws and regulations and the interpretation thereof, applicable to our software programs, products or services; 7 Table of Contents ● delays in obtaining regulatory approval for our products, services or software programs; ● interruptions to or other problems with our website and interactive user interface, information technology systems, manufacturing processes or other operations; ● general macroeconomic and industry conditions that affect end-user demand and end-user levels of product design and manufacturing, including the adverse effects of global macroeconomic uncertainties such as the macroeconomic uncertainty related to the armed conflict in Ukraine; and ● changes in accounting rules and tax laws. 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 2022, including increasing the costs of labor, energy, materials, and freight. We implemented price increases on many of our products and services in 2022 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 can 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, in can 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 2023 as well, which would harm our results of operations. Demand for additive manufacturing generally and our additive manufacturing software solutions, products and services in particular may not increase adequately, or at all. The industrial and medical industries are generally dominated by conventional production methods with limited use of additive manufacturing technology in certain specific instances. If additive manufacturing technology, in particular, but not limited to, for the production of end parts, does not gain more mainstream market acceptance, or gains market acceptance at a significantly slower pace than currently expected, 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 and fixtures 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. We are dependent upon sales to certain 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, and we expect additional growth to come from certain other specific markets, such as the eyewear and footwear markets. To the extent any of these industries experience, or continue to experience, a downturn, our results of operations may be adversely affected. Additionally, if any of these industries or their respective suppliers or other providers of manufacturing services develop new technologies or alternatives to manufacture the products that are currently manufactured using our 3D printing software, products and services, it may adversely affect our results of operations. If our relationships with suppliers, including with limited source suppliers of consumables, were to terminate or our manufacturing arrangements were to be disrupted, our business could be adversely affected. We purchase 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 that we use for our printing activities. Our reliance on a limited number of vendors involves a number of risks, including: ● potential shortages of some key consumables or other components; ● printed material performance or quality shortfalls, if traceable to particular consumables or other components, since the supplier of the faulty consumable or component cannot readily be replaced; ● discontinuation of a consumable or other component on which we rely; 8 Table of Contents ● potential insolvency of these vendors; and ● reduced control over delivery schedules, manufacturing capabilities, quality and costs. If certain suppliers were to decide to discontinue production, or the supply to us, of a 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, increases 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 can supply us 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. The dominant software subscription model in the industrial sector is changing, and we may not be successful in developing a cloud- based platform to offer our software. We offer most 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, and are in the process of continuing to integrate the Link3D platform into a unified additive manufacturing platform, or CO-AM, to offer our software products either by means of a SaaS or a cloud-based subscription model, there is no guarantee that we will be able to complete this integration successfully or in a timely manner or that our platform will be adopted by customers over other platforms. A SaaS or cloud-based software offering may differ significantly from the perpetual and annual licensing models that we have 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. Furthermore, any SaaS or cloud-based software products we offer may reside upon and be hosted by third party providers. A security breach, whether of our products, of our customers’ network security and systems or of third party hosting services, could disrupt access to our customers’ stored information and could lead to the loss of, damage to or public disclosure of our customers’ stored information. We may not be able to successfully adopt our software offering to the changing needs of the additive manufacturing market. While the current proto-typing market that we serve with our software solutions (in particular the Magics 3D Print Suite) is not expected to disappear, the main growth in additive manufacturing is expected to come from the use of 3D printing for the production of end parts. While we are investing significantly in the expansion of our current software product portfolio to also serve the needs of this new and growing market (in particular, with the development of the Materialise CO-AM platform), there can be no certainty that our new software offering will adequately serve the needs of this new market, will be operational in time to address these market needs, will be well received by the market or will effectively compete with other players in this market. 9 Table of Contents 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, and 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 member 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 the acquired company following the acquisition and to continue to attract such persons to our company. 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 result, the loss of such persons could adversely affect us. We may need to raise additional capital from time to time in order to meet our growth strategy and may be unable to do so on attractive terms, or at all. We intend to continue to make investments to support the growth of our business and may require additional funds to respond to business challenges, including the need to implement our growth strategy, increase market share in our current markets or expand into other markets, or broaden our technology, intellectual property or service capabilities. Accordingly, we may require additional investments of capital from time to time, and our existing sources of cash and any funds generated from operations may not provide us with sufficient capital. For various reasons, including the current macroeconomic environment or any noncompliance with existing or future lending arrangements, additional financing, may not be available when needed, or may not be available on terms favorable to us. If we fail to obtain adequate capital on a timely basis or if capital cannot be obtained on terms satisfactory to us, we may not be able to achieve our planned rate of growth, which will adversely affect our results of operations. Our international operations subject us to various risks, and our failure to manage these risks could adversely affect our results of operations. We face significant operational risks as a result of doing business internationally, including, among others: ● fluctuations in foreign currency exchange rates; ● potentially longer sales and payment cycles; ● potentially greater difficulties in collecting accounts receivable; ● potentially adverse tax consequences, including liabilities imposed from inconsistent enforcement; ● challenges in providing solutions across a significant distance, in different languages and among different cultures; ● the impact of global public health crises, including the impact that the ongoing COVID-19 pandemic could still have on some economies and markets; ● transportation delays; 10 Table of Contents ● becoming subject to the different, complex and changing laws, regulations and court systems of multiple jurisdictions and compliance with a wide variety of foreign laws, treaties and regulations; ● reduced protection of, or significant difficulties in enforcing, intellectual property rights in certain countries; ● difficulties in staffing and managing foreign operations, particularly in new geographic locations; ● restrictions imposed by local labor practices and laws on our business and operations, including unilateral cancellation or modification of contracts; ● expropriation or nationalization of property; ● rapid changes in global government, economic and political policies and conditions, political or civil unrest or instability, terrorism or pandemics, epidemics and other similar outbreaks or events, such as the armed conflict in Ukraine; ● operating in countries with a higher incidence of corruption and fraudulent business practices; ● seasonal reductions in business activity in certain parts of the world, particularly during the summer months in Europe; ● costs and difficulties of customizing products for foreign countries; and ● tariffs, trade barriers and other regulatory or contractual limitations on our ability to sell or develop our products in certain foreign markets. 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. On February 24, 2022, the Russian Federation invaded Ukraine, impacting 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 presently 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 geo-politically and in Ukraine. 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. In particular, although we have included under “Item 5. Operating and Financial Review and Prospects—D. Trend Information” of this annual report a discussion, based on our current assessment of the armed conflict in Ukraine, of how our business, results of operations, and financial condition could be impacted during fiscal 2023, this discussion should be considered as uncertain. While we expect to suffer adverse effects, the severity is currently impossible to assess. 11 Table of Contents 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, 2022, 61% of our revenue was generated, and approximately 75% of our total costs were incurred in euros. 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, including possible changes to the innovation income deduction regime in Belgium or the way it proportionately impacts our effective tax rate. 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. We may engage in acquisitions or investments that could disrupt our business, cause dilution to our shareholders and harm our financial condition and results of operations. In the past, we have acquired or invested in companies that we believe have products, services, competencies or capabilities that are a strategic or commercial fit with any of our businesses or that otherwise offer opportunities for us, and we intend to continue evaluating opportunities to do so. In connection with acquisitions or investments, we may: ● issue American Depositary Shares, or ADSs, or other forms of equity that would dilute our existing shareholders’ percentage of ownership; ● incur debt and assume liabilities; and/or ● incur amortization expenses related to intangible assets or incur large and immediate write-offs. If we complete an acquisition or investment, we cannot assure that it will ultimately strengthen our competitive position or that it will be viewed positively by customers, suppliers, employees, financial markets or investors. Furthermore, future acquisitions or investments could pose numerous additional risks to our operations, including: ● problems integrating the purchased business, products, services or technologies; ● challenges in achieving strategic objectives, cost savings and other anticipated benefits; ● increases to our expenses; ● the potential write down of assets or goodwill acquired in the context of an acquisition or investment; ● due diligence investigations failing to discover undisclosed liabilities or risks affecting the acquired businesses; ● the assumption of significant liabilities that exceed the limitations of any applicable indemnification provisions or the financial resources of any indemnifying party; ● inability to maintain relationships with key customers, vendors and other business partners of our current or acquired businesses; ● diversion of management’s attention from their day-to-day responsibilities; 12 Table of Contents ● difficulty in maintaining controls, procedures and policies during the transition and integration; ● entrance into marketplaces where we have no or limited prior experience and where competitors have stronger marketplace positions; ● potential loss of key employees, particularly those of the acquired entity; and ● historical financial information may no longer be representative or indicative of our results as a combined company. Alternatively, while certain acquisitions or investments may be of strategic importance for the execution of our business plan, we may not ultimately be able to complete such acquisitions or investments on favorable terms, or at all, which may in turn materially affect our ability to grow or even cause us to lose market share, and could have a material adverse effect on our business, financial condition and results of operations. We may enter into collaborations, in-licensing arrangements, joint ventures, strategic alliances or partnerships with third parties that may not result in the development of commercially viable products or the generation of significant future revenue. 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. 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. For example, we are currently involved in an arbitration dispute with Zimmer Biomet regarding certain alleged indemnification obligations. 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. Failure to comply with applicable anti-corruption and trade sanctions legislation could result in fines, criminal penalties and an adverse effect on our business. We operate in a number of countries throughout the world and we are committed to doing business in accordance with applicable anti-corruption laws. We are subject, however, to the risk that our officers, directors, employees, agents and collaboration partners may take action determined to be in violation of such anti-corruption laws, as well as trade sanctions administered by the Office of Foreign Assets Control and the U.S. Department of Commerce. Any such violation could result in substantial fines, sanctions, civil and/or criminal penalties or curtailment of operations in certain jurisdictions and might adversely affect our results of operations. In addition, actual or alleged violations could damage our reputation and ability to do business. 13 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 our 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. We rely on our information technology systems to manage numerous aspects of our business and customer and supplier relationships, and a disruption of these systems could adversely affect our results of operations. We rely on our information technology systems and databases to manage numerous aspects of our business and to provide analytical information to management. Our 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. Although we take steps to secure our information technology systems, including our computer systems, intranet and internet sites, email and other telecommunications and data networks, the security measures we have implemented may not be effective and our systems may be vulnerable to, among other things, 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, security breaches, computer viruses and other disruptive events. Any such disruption could adversely affect our reputation, brand and financial condition. In addition, during the next few years, we expect to gradually replace a number of our information technology systems with new, cloud-based systems. This transformation is intended to further increase our security and data integrity. Disruptions during the configuration, implementation or operation of, or during the migration to, these new systems may have an impact on our operations and could adversely affect us. 14 Table of Contents A breach of security in our products or computer systems may compromise the integrity of our products, harm our reputation, create additional liability and adversely impact our financial results. 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. Any of the foregoing could attack our products and computer systems. Despite significant efforts to create and continuously reinforce the security barriers to such programs, 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 vulnerable to such cyber-attacks, and our computer systems have been subject to certain cyber security incidents in the past. The impact of cyber-attacks could disrupt the proper functioning of our software products and computer systems, cause errors in the output of our or our customers’ work, allow unauthorized access to sensitive, proprietary or confidential information of our company, our customers or the patients that we and our customers serve through our medical solutions. Moreover, as we continue to invest in new lines of 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. If any of the foregoing occur, our reputation may suffer, customers may stop buying our products or services, we could face lawsuits and potential liability, and our results of operations could be adversely affected. We rely on third-party technology, platform, carriers, server and hardware providers and as well as local servers, and a failure of service by these providers or by our local servers could adversely affect our business and reputation. We use third party cloud providers to host a major part of our servers. If these providers are unable to handle current or higher volumes of use, experiences any interruption in operations or ceases 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. If we are forced to switch hosting facilities, we may not be successful in finding an alternative service provider on acceptable terms or in hosting the computer servers ourselves. 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. In addition to using third party cloud providers, we have also established local servers and infrastructure in multiple offices, including in Leuven. A failure of these local servers could adversely affect our business and reputation. Workplace accidents or environmental damage could result in substantial remedial obligations and damage to our reputation. Accidents or other incidents that occur at our service centers and other facilities or involve our personnel or operations could result in claims for damages against us. In addition, in the event we are found to be financially responsible, as a result of environmental or other laws or by court order, for environmental damages alleged to have been caused by us or occurring on our premises, we could be required to pay substantial monetary damages or undertake expensive remedial obligations. The amount of any costs, including fines or damages payments that we might incur under such circumstances could substantially exceed any insurance we have to cover such losses. Any of these events, alone or in combination, could have a material adverse effect on our business, financial condition and results of operations and could adversely affect our reputation. 15 Table of Contents Our operations are subject to environmental laws and other government regulations that could 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. 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 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 seven 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, we could suffer damage to our reputation, and we might need to modify our standard 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. 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. We may not have adequate insurance 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 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 16 Table of Contents ● 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. Current and future global macroeconomic uncertainties and political conditions may adversely affect our results of operations. Our results of operations could be substantially affected not only by global economic conditions, but also by local operating, economic, public health or environmental conditions, which can vary substantially across regions. Unfavorable conditions can 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. Certain macroeconomic events could have a wide-ranging and prolonged impact on the general business environment, which could also adversely affect us. Current macroeconomic events that we believe could impact us are the following: ● Geopolitical instability resulting from, among other factors, the armed conflict in Ukraine; ● The risk of potential recessions, continued rising interest rates, inflation and labor shortages in Europe and the United States; ● Recent turmoil in the global banking system; ● Disruptions caused by the ongoing COVID-19 pandemic and related responses thereto in certain economies and markets, including most recently, in China; and ● In general, the economic and political challenges faced by, among others, China, certain Eurozone countries and the United States. We cannot predict the likely duration and severity of these economic and political developments, which could affect us in numerous ways, many of which we cannot predict. For example, the existence of inflation in certain economies has resulted in, and may continue to result in, rising interest rates and capital costs, supply shortages, increased costs of labor, components, manufacturing and freight costs, as well as weakening exchange rates and other similar effects. As a result of inflation, we have experienced and may continue to experience cost increases. Although we take measures to mitigate the effects of inflation, if these measures are not effective, our business, financial condition, results of operations and liquidity could be materially adversely affected. Even if such measures are effective, there could be a difference between the timing of when those beneficial actions impact our results or operations and when the cost of inflation is incurred. In addition, political and economic developments could also result in changes to legislation or reformation of government policies, rules and regulations, including in relation to tax and trade. Such changes could have a significant impact on our business by increasing the cost of doing business, affecting our ability to sell our software, products and services and negatively impacting our profitability. For example, as a result of the Russian Federation’s invasion of Ukraine, as a result of which immediate severe trade sanctions were issued, in particular by the United States and the European Union. 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 U.S. federal and state, E.U. 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. 17 Table of Contents 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, privacy laws such as the California Consumer Privacy Act, or CCPA, effective as of January 1, 2020, which was recently amended and expanded by the California Privacy Rights Act, or CPRA, as of January 1, 2023. 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 cannot yet predict the impact of the CCPA, as amended by the CPRA, on our business or operations, but it may require us to modify our data processing practices and policies and to incur substantial costs and expenses in an effort to comply. In the European Union, the General Data Protection Regulation, or the GDPR, was passed on May 24, 2016, and replaced the E.U. Data Protection Directive when it came into force on May 25, 2018. 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 E.U. 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 U.K.-specific amendments), or U.K. GDPR. In ensuring continued compliance with the E.U. regime, our transfer of any personal data from the European Union to the United States must be done in a manner which satisfies E.U. cross-border data transfer requirements. The E.U.-U.S. Privacy Shield, which had been adopted by the United States and the European Union as a framework for protecting the fundamental rights of anyone in the European Union whose personal data is transferred to the United States for commercial purposes, was subsequently invalidated by the European Court of Justice on July 16, 2020 for not meeting E.U. regulatory requirements. We are investigating and undertaking appropriate steps to mitigate the risks caused by the invalidation of the Privacy Shield, including the use and implementation of the standard contractual clauses for the transfer of personal data to third countries as published by the European Commission on June 4, 2021. 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 expect to do business in the future. 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, 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 U.K. 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 to 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 you 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. 18 Table of Contents Risks Related 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 U.S. Food and Drug Administration, or the 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. 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 Directive. Under the European Medical Device Directive, 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 Directive. This process has been impacted by the general lack of capacity of notified bodies properly designated under the E.U. Medical Device Regulation, which became effective on May 26, 2021. These issues may delay the (re)certification and commercialization of our new or updated medical products in the European Economic Area, or EEA. Similarly, in the United States, we are required to obtain clearance or approval from the FDA prior to marketing our medical products. 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, labelling 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 can result in various actions that could adversely impact our medical operations, including: ● the recall or seizure of products; 19 Table of Contents ● 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 exclusion of our products from being reimbursed by healthcare programs in the European Union or U.S. 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. If investigated, 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. 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, labelling 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 can 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. Modifications to our medical products marketed in the United States may require new 510(k) clearances or premarket approvals, or may require us to cease marketing or recall the modified products until clearances are obtained. 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 FDA requires every manufacturer to make the determination regarding the need for a new 510(k) clearance or PMA in the first instance, but the FDA may (and often does) review the manufacturer’s decision. The FDA may not agree with a manufacturer’s decision regarding whether a new clearance or approval is necessary for a modification, and may retroactively require the manufacturer to submit a premarket notification requesting 510(k) clearance or an application for PMA. We have made modifications to our medical products in the past and may make additional modifications in the future that we believe did not or will not require additional clearances or approvals. No assurance can be given that the FDA will agree with any of our decisions not to seek 510(k) clearance or PMA. If the FDA requires us to cease marketing and recall the modified device until we obtain a new 510(k) clearance or PMA, our medical business, financial condition, results of operations and future growth prospects could be materially adversely affected. Further, our medical products could be subject to recall if the FDA determines, for any reason, that our products are not safe or effective. Any recall or FDA requirement that we seek additional approvals or clearances could result in significant delays, fines, increased costs associated with modification of a product, loss of revenue and potential operating restrictions imposed by the FDA. 20 Table of Contents Healthcare policy changes, including legislation to reform the U.S. healthcare system, could adversely affect us. From time to time, legislation is drafted and introduced that could significantly change the statutory provisions governing the clearance or approval, manufacture and marketing of a medical device. In addition, regulations and guidance are often revised or reinterpreted in ways that may significantly affect our medical business and our medical products. It is impossible to predict whether legislative changes will be enacted or regulations, guidance or interpretations changed, and what the impact of such changes, if any, may be. For instance, in 2010, the U.S. Patient Protection and Affordable Care Act, as amended by the U.S. Health Care and Education Reconciliation Act of 2010, or collectively, the PPACA, was enacted, which included, among other things, the following measures: a Patient-Centered Outcomes Research Institute to oversee, identify priorities in and conduct comparative clinical effectiveness research; reporting and disclosure requirements on device manufacturers for any “transfer of value” made or distributed to prescribers and other healthcare providers, effective March 30, 2013 (referred to as the Physician Sunshine Payment Act); payment system reforms including a national pilot program on payment bundling to encourage hospitals, physicians and other providers to improve the coordination, quality and efficiency of certain healthcare services through bundled payment models, beginning on or before January 1, 2013; and an independent payment advisory board that will submit recommendations to reduce Medicare spending if projected Medicare spending exceeds a specified growth rate. Some of the provisions of the PPACA have yet to be fully implemented, while certain provisions have been subject to U.S. judicial and Congressional challenges. Efforts to repeal and replace the PPACA have been ongoing since the 2016 election, but it is unclear if these efforts will be successful. Since January 2017, former President Trump signed Executive Orders and other directives designed to delay, circumvent or loosen the implementation of certain provisions requirements mandated by the PPACA or otherwise circumvent some of the requirements for health insurance mandated by the PPACA. In addition, as part of the December 2017 Tax Cuts and Jobs Act, the “individual mandate,” which required individuals to purchase insurance, was repealed. Furthermore, in December 2018, a U.S. District Court Judge in the Northern District of Texas ruled that the PPACA is unconstitutional in its entirety because such individual mandate was repealed, although the U.S. District Court Judge and former President Trump, among others, had acknowledged the ruling would have no immediate effect pending appeal. Thus, the full impact of the PPACA, any law repealing or replacing elements of it, and the political uncertainty surrounding any repeal or replacement legislation on our business remains unclear. We cannot predict what healthcare programs and regulations will be ultimately implemented at the U.S. federal or state level, or at the E.U. level or within the implementing legislation of the individual E.U. Member States, or the effect of any future legislation or regulation. However, these provisions as adopted could meaningfully change the way healthcare is delivered and financed, and 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. In addition, in the future there may continue to be additional proposals relating to the reform of the healthcare systems of the United States, the European Union, any individual Member State of the European Union or any other jurisdiction where we may operate. For example, the new E.U. Medical Device Regulation became effective on May 26, 2021. The Medical Device Regulation, among other things: ● strengthens the rules on placing devices on the market and reinforce surveillance once they are available; ● establishes explicit provisions on manufacturers’ responsibilities for the follow-up of the quality, performance and safety of devices placed on the market; ● improves the traceability of medical devices throughout the supply chain to the end-user or patient through a unique identification number; and ● strengthens rules for the assessment of certain high-risk devices, such as implants, which may have to undergo an additional check by experts before they are placed on the market. 21 Table of Contents Transition from the regulation of our products under the current E.U. regulatory framework to regulation under the Medical Device Regulation may require a substantial transition effort by us. In addition, detail as to how certain aspects of the Medical Device Regulation will be applied remains unclear. Failure to update our quality system and regulatory documentation could delay our transition to compliance with the Medical Device Regulation and delay or prevent us from obtaining new CE Certificates of Conformity under the Regulation. As a result, transition from compliance with the current E.U. regulatory framework to the Medical Device Regulation could result in disruption to our business in the European Economic Area, which could adversely affect our business, results of operation and financial condition. 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 results of operations due to increased pricing pressure in certain or all of the markets in which we operate. Governments, hospitals and other third party payors could reduce the amount of approved reimbursements for our products. Reductions in reimbursement levels or coverage or other cost-containment measures could unfavorably affect our future results of operations. 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. 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, 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. 22 Table of Contents 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 that 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 labelling 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. 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. Under the FDA medical device reporting regulations, or MDR, 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 ourselves 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. In the EEA, we must comply with the E.U. Medical Device Vigilance System, 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 system, incidents must be reported to the competent authorities of the Member States of the EEA. An incident is defined as any malfunction or deterioration in the characteristics and/or performance of a device, as well as any inadequacy in the labelling or the instructions for use which, directly or indirectly, might lead to or might have led to the death of a patient or user or of other persons or to a serious deterioration in their state of health. Incidents are evaluated by the EEA 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 E.U. Medical Device Vigilance System is further intended to facilitate a direct, early and harmonized implementation of Field Safety Corrective Actions, or FSCAs, across the Member States of the EEA where the device is in use. An 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. An 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. 23 Table of Contents 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 U.S. 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, labelling, 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. 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. We may be subject to or otherwise affected by U.S. federal and state, European or other healthcare laws, including fraud and abuse and health information privacy and security laws, and could face substantial penalties if we are unable to fully comply with such laws. Healthcare regulation by U.S. federal and state, European or other governments could significantly impact our medical business. Healthcare fraud and abuse and health information privacy and security laws potentially applicable to our medical operations include: ● the U.S. federal Anti-Kickback Law, which constrains our marketing practices and those of our independent sales agencies, educational programs, pricing, bundling and rebate policies, grants for physician-initiated trials and continuing medical education, and other remunerative relationships with healthcare providers, by prohibiting, among other things, soliciting, receiving, offering or providing remuneration, intended to induce the purchase or recommendation of an item or service reimbursable under a U.S. federal healthcare program, such as the Medicare or Medicaid programs; ● U.S. federal false claims laws which prohibit, among other things, knowingly presenting, or causing to be presented, claims for payment from Medicare, Medicaid, or other third party payors that are false or fraudulent; ● HIPAA, and its implementing regulations, which created federal criminal laws that prohibit executing a scheme to defraud any healthcare benefit program or making false statements relating to healthcare matters and which also imposes certain regulatory and contractual requirements regarding the privacy, security and transmission of individually identifiable health information; 24 Table of Contents ● U.S. state laws analogous to each of the above federal laws, such as anti-kickback and false claims laws that may apply to items or services reimbursed by any third party payor, including commercial insurers, and state laws governing the privacy and security of certain health information, many of which differ from each other in significant ways and often are not pre- empted by HIPAA, thus complicating compliance efforts; and ● similar foreign laws and regulations governing healthcare fraud and abuse, patient data privacy, interactions with healthcare professionals and related laws and regulations that apply to us in the countries in which we operate. If our past or present operations are found to be in violation of any of such laws or any other governmental regulations that may apply to us, we may be subject to penalties, including civil and criminal penalties, damages, fines, exclusion from U.S. federal healthcare programs and the curtailment or restructuring of our operations. 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. Any penalties, damages, fines, curtailment or restructuring of our operations could adversely affect our ability to operate our medical business and our financial results. The risk of our company being found in violation of these laws is increased by the fact that many of them have not been fully interpreted by the regulatory authorities or the courts, and their provisions are open to a variety of interpretations. Further, the PPACA, among other things, amends the intent requirement of the U.S. federal anti-kickback and criminal health care fraud statutes. A person or entity no longer needs to have actual knowledge of this statute or specific intent to violate it. In addition, the PPACA provides that the government may assert that a claim including items or services resulting from a violation of the U.S. federal anti-kickback statute constitutes a false or fraudulent claim for purposes of the false claims statutes. Any action against us for violation of these laws, even if we successfully defend against them, could cause us to incur significant legal expenses and divert our management’s attention from the operation of our business. Risks Related to Our Intellectual Property If we are unable to obtain 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 we may not be able to obtain foreign patents or elect to file applications corresponding to our U.S., 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. Any of the foregoing events would lead to increased competition and lower revenue or gross margins, which could adversely affect our results of operations. Moreover, ongoing changes to the U.S. patent laws may impact our ability to obtain and enforce our intellectual property rights. In recent years, the courts have interpreted U.S. patent laws and regulations differently, and in particular the U.S. 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. 25 Table of Contents We may not be able to protect our trade secrets and intellectual property. While some of our technology is licensed under patents belonging to others or is covered by process patents which are owned or applied for by us, much of our technology is not protected by patents. Furthermore, patents are jurisdictional in nature and therefore only protect us in certain markets, rather than globally. 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 can 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 can be protected by patents or as trade secrets, we may face increased competition from other companies, 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. In connection with the enforcement of our intellectual property rights, opposing third parties from obtaining patent rights or disputes related to the validity or alleged infringement of our or third party intellectual property rights, including patent rights, we have been and may in the future be subject or party, directly or indirectly, to claims, negotiations or complex, protracted litigation or arbitration proceedings. 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 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 we 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 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 can be costly and disruptive to our business operations by diverting attention and energies 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. 26 Table of Contents We cannot predict the outcome of an arbitration proceeding in which we are involved. On November 15, 2021, we received a written notice from counsel for Zimmer Biomet, informing us of Zimmer Biomet’s decision to file a request for arbitration with the Belgian Centre for Arbitration and Mediation. Zimmer Biomet believes that we have a contractual obligation pursuant to the terms of our collaboration to indemnify Zimmer Biomet for the expenses it incurred as a result of its settlement with Conformis, Inc. of a patent dispute related to certain joint replacement devices. We believe there are meritorious defenses to Zimmer Biomet’s claim and intend to contest it vigorously. However, an adverse resolution of this arbitration could have an adverse effect on our business, financial condition, results of operations and cash flows in the period in which the arbitration is resolved. No amounts have been accrued for this loss contingency. Obtaining and maintaining our patent protection depends on compliance with various procedural, documentary, fee payment and other requirements imposed by governmental patent agencies, and our patent protection could be reduced or eliminated for non- compliance with these requirements. Periodic maintenance fees on any issued patent are due to be paid to governmental patent agencies, including the U.S. Patent and Trademark Office, or USPTO, in several stages over the lifetime of the patent. The USPTO and various foreign governmental patent agencies require compliance with a number of procedural, documentary, fee payment and other similar provisions during the patent application process. While an inadvertent lapse can in many cases be cured by payment of a late fee or by other means in accordance with the applicable rules, there are situations in which noncompliance can result in lapse of the patent or patent application, resulting in partial or complete loss of patent rights in the relevant jurisdiction. Non-compliance events that could result in lapse of a patent or patent application include, but are not limited to, failure to respond to official actions within prescribed time limits, non-payment of fees and failure to properly legalize and submit formal documents. If we or our licensors fail to maintain the patents and patent applications covering our products and processes, our competitive position could be adversely affected. We may be subject to claims that our employees have wrongfully used or disclosed alleged trade secrets. Certain of our past and present employees were previously employed at other companies, including our competitors or potential competitors. Some of these employees executed proprietary rights, non-disclosure and non-competition agreements in connection with such previous employment. Although we try to ensure that our employees do not use the proprietary information or know-how of others in their work for us, we may be subject to claims that we or these employees have used or disclosed intellectual property, including trade secrets or other proprietary information, of any such employee’s former employer. We are not aware of any threatened or pending claims related to these matters, but in the future litigation may be necessary to defend against such claims. If we fail in defending any such claims, in addition to paying monetary damages, we may lose valuable personnel or intellectual property rights. Even if we are successful in defending against such claims, litigation could result in substantial costs and be a distraction to management. 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. 27 Table of Contents 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, BASF 3D Printing Solutions GmbH and HOYA. 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 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. For additional information, see “Item 4. Information on the Company—B. Business Overview—Intellectual Property.” 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 that in 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 Related to the ADSs The ADSs may experience price and volume fluctuations. The stock market generally has 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 the ADSs, regardless of our actual operating performance. The market price and liquidity of the market for the ADSs 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, the continued rise in interest rates, ongoing supply chain shortages, local and national elections, international currency fluctuations, epidemics and pandemics, corruption, political instability and acts of war, such as the armed conflict in Ukraine, 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 by us or one of our competitors; 28 Table of Contents ● 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; ● 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 the ADSs. Members of our board of directors and senior management own a significant percentage of our ordinary shares and are able to exert significant influence over matters subject to shareholder approval. Members of our board of directors and senior management beneficially owned approximately 57.66% of our outstanding ordinary shares (including ordinary shares represented by ADSs), as of March 22, 2023. 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 Chief Executive Officer, Hilde Ingelaere, an Executive Vice President of our company who is also Mr. Vancraen’s spouse, and their three children, Linde, Sander 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, a majority of our directors must be appointed by our shareholders from a list of candidates proposed by the Family Shareholders. 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 the ADSs. The dilutive effect of our warrants could have an adverse effect on the future market price of the ADSs or otherwise adversely affect the interests of our shareholders. Based on outstanding granted warrants, as of December 31, 2022, there were outstanding granted warrants to subscribe for an aggregate of 77,709 ordinary shares at a weighted average exercise price of €8.37 per share. The warrants likely will be exercised if the market price of 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. 29 Table of Contents You 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 your right to vote. 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. You 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 you 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. You will receive these distributions in proportion to the number of our ordinary shares your 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. 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 you 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 you. These restrictions may have a material adverse effect on the value of your ADSs. We have no present intention to pay cash dividends on our ordinary shares in the foreseeable future and, consequently, your only opportunity to achieve a return on your investment during that time is if the price of 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. 30 Table of Contents As a foreign private issuer, 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 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 reporting and “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. 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 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, 2023. 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 our outstanding ordinary shares are held of record by U.S. residents. As of December 31, 2022, 1.6% 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. Our remediation efforts may not enable us to avoid a material weakness in the future. 31 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 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 our management is required to devote substantial time to new compliance initiatives. As a company whose ADSs are publicly traded in the United States, we have incurred and will incur significant legal, accounting, insurance and other expenses that we did not incur prior to our initial public offering. 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 have imposed various requirements on public companies, including requiring establishment and maintenance of effective disclosure and financial controls. 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. 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 its committees. Furthermore, if we are unable to satisfy our obligations as a public company, we could be subject to delisting of the ADSs, fines, sanctions and other regulatory action and potentially civil litigation. In order to satisfy our obligations as a U.S. public company, we may need to hire or engage additional qualified accounting and financial personnel and consultants with appropriate experience. As a U.S. public 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. You may be subject to limitations on the transfer of your ADSs. Your 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, you may be unable to transfer your ADSs when you wish to. If securities or industry analysts do not publish research or reports about our business, or if they adversely change their recommendations regarding the ADSs, the market price for the ADSs and trading volume could decline. The trading market for the ADSs is influenced by research or reports that industry or securities analysts publish about our business. If one or more analysts who cover us downgrade the ADSs, the market price for the ADSs 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 to decline. 32 Table of Contents 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. 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. 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 but are not a listed company 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 do not qualify as a listed company (genoteerde vennootschap / société cotée) because none of our securities are listed on any regulated market in the EEA. The Belgian corporate law provisions that are applicable to Belgian listed companies do therefore not apply to us. Furthermore, we are not subject to most of the disclosure obligations applicable to Belgian listed companies. As a result, shareholders of our company may not enjoy certain of the rights and protection generally afforded to shareholders of a Belgian listed company. You 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 you would typically enjoy as a shareholder of a U.S. corporation under applicable U.S. federal and state laws. 33 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, in some cases, that the relevant acts were specifically mentioned in the convening notice to the shareholders’ meeting deliberating on the discharge. 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, you could receive less protection as a shareholder of our company than you would as a shareholder of a U.S. corporation. As a foreign private issuer, 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. 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 it in expense or liability unless it is indemnified to its 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. 34 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. 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 shares. Any future payments of cash dividends on shares will be denominated in euro. The U.S. dollar—or other currency—equivalent of any dividends paid on our shares or received in connection with any sale of our shares could be adversely affected by the depreciation of the euro against these other currencies. 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. 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 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. 35 Table of Contents ITEM 4. INFORMATION ON THE COMPANY A. History and Development of the Company Materialise NV was incorporated in Belgium on June 28, 1990 as a limited liability company under Belgian company law. In January 2022, we filed a voluntary application to strike Materialise UK off the UK company register. A notice in this respect was published in The London Gazzette on February 8, 2022. As a result, Materialise UK has been struck off the register and was dissolved on April 26, 2022. On September 1, 2022, we acquired Identify3D, Inc., a company that develops software to encrypt, distribute and trace the flow of digital parts across complex supply chains. This acquisition was effected by our U.S. subsidiary, Materialise USA, LLC. The acquisition of Identify3D is intended to strengthen the security features of our CO-AM platform. On October 1, 2022 and December 31, 2022, respectively, we merged Link3D Inc. and Identify3D, Inc. into Materialise USA, LLC, as a result of which Link3D and Identify3D ceased to exist. Our principal executive and registered offices are located at Technologielaan 15, 3001 Leuven, Belgium. Our telephone number is +32 (16) 39 66 11. We are registered with the Register of Legal Entities of Leuven under the number 0441.131.254. Our agent for service of process in the United States is Materialise USA, LLC, located at 44650 Helm Ct., Plymouth, Michigan 48170, telephone number (734) 259-6445. Our internet website is www.materialise.com. The information contained on, or accessible through, our website is not incorporated by reference into this annual report and should not be considered a part of this annual report. The SEC maintains an internet website that contains reports, proxy and information statements, and other information regarding issuers that file electronically with the SEC at www.sec.gov. Capital Expenditures (Property Plant and Equipment and Intangible Assets) Our capital expenditures amounted to € 24.8 million, € 11.7 million and € 17.7 million for the years ended December 31, 2022, 2021, and 2020, respectively. In 2022, our main capital expenditures were € 7.3 million for our new metal production facility in the United States, € 7.9 million for the expansion of our production capacity in Germany and € 2.4 million for our internal digital transformation program. In 2021, our main capital expenditures were € 1.7 million for our internal digital transformation program, € 1.6 million for a new building in Germany and € 1.0 million for the transformation of our platform architecture which was partially impaired in 2022. In 2020, our main capital expenditures were € 2.8 million for office software and € 2.2 million for our internal digital transformation program, € 4.9 million for the new building in Germany and € 7.1 million for new machinery and installations in Belgium, Germany, Poland, Brazil and the United States.

Software Products. 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. 38 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 export standard tessellation language, or STL, files ready for additive manufacturing. Magics’ applications include repairing and optimizing 3D models; analyzing parts; making process-related design changes on customers’ STL 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. In 2021, we won the 3DPrinting Industry’s “Software Tool or Company of the Year” award for our Magics software. 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).

CO-AM is an additive workflow and digital manufacturing software platform 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. 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 & 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 while also providing a connector between Streamics and CO-AM that will allow current Streamics users to start using CO-AM applications while still making use of Streamics for the planning of their 3D printing capacity. 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-maticSTL. 3-maticSTL 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 STL files. Using Materialise consultancy services, targeted design automation solutions can be created for specific workflows. 39 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 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. 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 STL support generation, optimizing the STL 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. In 2018, we won the TCT SOFTWARE AWARD 2018 for e-Stage for metal. ● Materialise Controller. Materialise Controller controls and steers additive manufacturing machines using embedded Materialise software, and is fully integrated into the Materialise 3D printing software platform. It is engineered towards research and development applications, machine manufacturers and those who want to control or adapt the production process to their specific needs. ● Materialise Storefront.

Companies can also choose to deploy and run the application on site. ● Materialise Process Tuner. An intuitive online platform that helps manufacturing companies, service bureaus and machine builders speed up the process tuning that is required for mass-manufacturing 3D printed parts. ● Materialise Workflow Automation. This solution enables the user to leverage the full power of the Materialise Software technology (as also available through Materialise Magics) in creating specific end-to-end workflows, which can be executed automatically and autonomously, or can be called from other software solutions like Magics. Workflow Automation provides the possibility to script simple workflows or to create complex business process workflows using a graphical user interface. The workflows can be executed in the cloud, on premise or on the user’s workstation. ● 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. 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. 40 Table of Contents 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 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 part manufacturing market. We believe that we can continue to expand our market penetration through expanding relationships with customers and OEMs, and through the continued innovation of our software products to adapt to and meet market demands. In order to be able to do so, we intend to bring our teams closer to our customer base worldwide, which will require continued investments in the expansion of our marketing and sales presence. In order to be able to meet the demands of new entrants on the market and to better address the needs of the end parts market, we also intend to continue to invest significantly in the development of our software tools and solutions, including furthering their compatibility with as many 3D printers on the market as possible.

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 services for their review and approval. In most cases, 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 SurgiCase tool, 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 SurgiCase tool is rebranded and adapted to the specific product offering and needs of our collaboration partners. 42 Table of Contents In many cases surgeons use personalized surgical guides or implants to translate the surgical plan into the operating room.

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. 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 Mimics Innovation Suite, 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 in the shorter term and the respiratory markets in the longer term. Our Materialise Manufacturing Segment In our Materialise Manufacturing segment, we primarily offer 3D printing services to industrial and commercial customers, the majority of which are located in Europe.

Our service centers offer a variety of 3D printing technologies including stereolithography, laser sintering, Filament Fusion, or FDM, PolyJet, Multi Jet Fusion, selective laser melting, or SLM, and vacuum casting. We have a dedicated production line for making aerospace-certified components using a number of technologies and materials. Specialty Industrial Solutions. We have developed additive manufacturing solutions that serve certain specialty industrial applications. Our RapidFit+ business utilizes additive manufacturing to provide customers active in the automotive market with customized, highly precise and, in certain cases, patent protected measurement and fixturing tools. Using additive manufacturing technology, we believe that RapidFit+ fixtures provide more functionality and flexibility than the traditional fixtures that are currently widely used in the automotive industry. We also offer production tooling that we believe has substantially better ergonomics and improved functionality compared to traditional fixtures. ACTech provides specialized solutions mainly for the automotive industry. In particular ACTech supplies prototyping of highly complex metal components through casting techniques that result in products that have a production grade performance. The casting is done using state-of-the-art 3D printed sand molds, while the final functionality of the components is achieved by a fully integrated post processing of the components in our CNC workshop. Wearables initiatives in consumer industry. We have developed two wearables verticals for the consumer market. We believe 3D printing and design automation has great potential to help both consumers and healthcare professionals improve comfort, health and performance through personalized eyewear or footwear. In our eyewear vertical, we offer a complete end-to-end solution for 3D-printed, often custom, eyewear frames. Based on a scan, patented technology identifies the critical parameters to automatically design eyewear that is customized to a person’s face. The resulting file can be printed in our eyewear production line, and we provide the necessary finishing, assembly steps and packaging. Through Materialise Motion, we offer a full suite of solutions for footcare professionals. We offer digital measurement tools and personalized solutions to footcare professionals treating foot or gait problems. By means of our foot scan plates, we can capture a dynamic scan of a person’s foot sole and combined with our software tools, we create custom insoles based on this scan. The insoles are 3D printed, finished and assembled in a dedicated production line. Our research and product development teams aim to build a growing suite of solutions for patients with different types of motion problems. Sales and Marketing. We market our services to our additive manufacturing solutions business customers using our sales force and through our website. Our more complex product offerings are addressed directly by our specialized sales teams who are located throughout Europe near our larger accounts and who align our customers’ needs with the wide range of 3D printing technologies or market-specific solutions that we offer. More straightforward products can be ordered directly by our customers through our “Materialise OnSite” or i.materialise web portals, a proprietary automated system that takes orders, provides quotes and manages the printing process from start to finish, and allows customers to track the manufacturing and shipment process of their product online. Within our larger sales teams, specialized sales managers focus either on rapid prototyping, which is our traditional and well-established market, or the additive manufacturing of end-use production parts, which is the market where we see opportunities for significant growth. Our marketing team in Belgium oversees our global marketing strategy. 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, healthcare, semiconductor, industrial goods, art and design and consumer products industries. For these customers, we offer a complete set of services ranging from consultancy and co-creation, to design and engineering, rapid prototyping, and certified manufacturing of end-use parts. 45 Table of Contents Through our consultancy offering, which we brand as Materialise Mindware, we work together with customers to solve complex design challenges and to discuss how the introduction of 3D printing can affect product development, manufacturing workflow, business models and customer experiences. For example, a co-creation with HOYA, in collaboration with Hoet Design Studio, saw the launch of the world’s first vision-centric, 3D-tailored eyewear solution, Yuniku. Yuniku enables individualized lens and frame design through a sophisticated end-to-end digital supply chain, which includes a custom 3D scanner and software platform, co-created by us and HOYA, directly linked to our eyewear manufacturing factory. 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 trainings to engineering professionals active in various markets to accelerate the adoption of design for additive manufacturing. The customers of both our Materialise OnSite and i.materialise platforms 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. For i.materialise, while there is a potential to address the wide consumer market with this platform, we prefer to describe our current customers as “home professionals.” Our i.materialise client base includes independent designers and CAD hobbyists that often sell their creations or their services to others, including, in certain instances, through the i.materialise gallery. Through i.materialise’s APIs, companies can also partner with i.materialise to give their own customers a cloud-based, 3D-printing solution on their website, streamlining the ordering, manufacturing and shipping processes through a direct link to our factory for 3D printing. Since 2016, Microsoft has been using the i.materialise API to offer a cloud-based 3D print solution for Windows 10 users, and PTC did the same for Creo 4.0 software users. 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. 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 Cresilas, 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. While there are multiple start-up companies seeking to address the home 3D printing services market, we believe that Shapeways and Sculpteo are the most prominent direct competitors of i.materialise based on their global reach. i.materialise focuses on standing out as a brand in terms of service and reliability. 46 Table of Contents 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 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, Brazil, the Czech Republic, Germany, Poland, Japan and the United States. We print substantially all of products in-house using a variety of technologies, including stereolithography, laser sintering, FDM, PolyJet, powder binding, Multi Jet Fusion, Powder Bed Fusion and vacuum casting, and only subcontract the manufacture of products if certain other technologies (such as CNC machined components) are required or for capacity balancing purposes. As of December 31, 2022, we operated a total of 205 3D printers, six vacuum casting machines and 27 CNC machines at these service centers, which include distinct areas dedicated to the machinery, quality control, cleaning and labelling of our products. The table below provides selected information about our 3D printers and vacuum casting machines: Size Manufacturer Number Technology Stereolithography DLP PolyJet FDM Laser Sintering Multi Jet Fusion Sand Binding Vacuum Casting Small/Medium Size Medium Size Mammoth 3D Systems Corporation / Other Materialise / Stratasys Materialise(1) Small Size Connex Small Size(2) Medium Size(3) Large Size(4) Small Size Medium Size Large Size Medium Size Large Size Small Size Medium Size Medium Size Large Size Asiga Stratasys Ltd.

The original curtain coat machines had a medium sized build volume. These medium sized machines have subsequently been adapted to become the extra- large sized Mammoth machines. (2) Small size machines are machines with a build volume of less than 250×250×250 mm. (3) Medium size machines have a build volume of less than 500×500×500 mm. (4) Large size machines have a build volume of more than 500×500×500 mm. As of December 31, 2022, 49 printers produced parts exclusively for our Materialise Medical segment, while the other 156 printers and six vacuum casting machines produced parts for our Materialise Manufacturing segment. 47 Table of Contents As of December 31, 2022, 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 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. With our strategic partnership with BASF 3D Printing Solutions GmbH, we are working towards offering to the market open solutions in terms of materials and software through which the user of additive manufacturing equipment can choose functionalities that best suit the user. 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, physics and chemistry. We have a long history of research and development through collaborations, which augment our internal development efforts. As of December 31, 2022, we were active in over 20 government funded research projects and we also employed multiple researchers with a 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, 2022, we had more than 50 active research and development projects in various stages of completion and approximately 478 FTEs and fully dedicated consultants working on research and development in our facilities in Belgium, France, Germany, the United Kingdom, the United States, Ukraine and Malaysia. Our research and development projects include (but are not limited to) the following: 1. 2. 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; 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); 48 Table of Contents 3. 4. 5. 6. 7. 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; research projects on the use of virtual and augmented reality by our Materialise Medical segment; research and development projects on smart digital technologies for the large-scale personalization of wearables; various research projects on the use of artificial intelligence and (deep) machine learning in the fields of image processing and additive manufacturing; and 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. 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, 2022, our portfolio of intellectual property featured 449 issued patents and an additional 132 pending patent applications primarily in the United States, the European Union and Japan. Of these, our issued patents expire between approximately 2020 and 2035, 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” and “ACTech” and trademark registrations and pending applications for many of our services and software solutions in those territories where we have substantial sales, including “Streamics”, “Mimics”, ”3-matic”, ”Inspector”, “Magics”, “RapidFit+”, “MGX by Materialise”, “Heartprint”, “ADaM”, “Engineering on Anatomy”, “Surgicase”, “Enlight”, “Mindware” and “Phits”, 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. 49 Table of Contents 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. Our headquarters in Belgium, our manufacturing site in Poland, and ACTech’s headquarters in Germany, follow the ISO 14001:2015 criteria for an effective environmental management system. These sites are ISO 14001:2015 certified. Compliance with laws and regulations relating to the discharge of materials into 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; 50 Table of Contents ● 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, including reporting of deaths or serious deterioration in the state of health and malfunctions that, if they were to recur, could lead to death or serious deterioration in the state of health; ● record keeping procedures; ● registration for reimbursement; and ● necessity of testing performed in country by distributors for licenses. 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 required us to adopt a series of measures and we will continue to update our systems and product registrations during the provided transition period to comply with this new Regulation. 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 have obtained 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. 51 Table of Contents C.

This acquisition was effected by our U.S. subsidiary, Materialise USA, LLC, and subsequently Identify3D was merged into Materialise USA. The acquisition of Identify3D is intended to strengthen the security features of our CO-AM platform. Growth Strategy In general, our strategy is built on the development and sale of two different sets of product portfolios: our horizontal and our vertical solutions. ● Each of our segments has what we call a horizontal product offering that addresses a broad set of needs of customers that make use of additive manufacturing: our market leading Magics Software Platform and the CO-AM platform that we launched in 2022 in our Materialise Software segment, the Mimics Innovation Suite in our Materialise Medical segment and the additive manufacturing services that we offer through our Materialise Manufacturing segment. We believe that each of these horizontal platforms has the potential of continuing to grow as the adoption of additive manufacturing by our customers in each of our segments grows. ● Second, leveraging on the technological and market knowledge that we gain as we bring our horizontal offerings to the market, we have built a select number of what we call vertical applications of 3D printing. These vertical applications, which address the specific needs of a particular subset of customers in a much more specific manner, include our surgical knee guides and personalized CMF guides and implants in our Materialise Medical segment and our measurement fixtures and personalized foot and eyewear products in our Materialise Manufacturing segment. We believe that this more focused presence in a few applications of 3D printing has the potential to further boost our growth. Within the horizontal and vertical frameworks, each of our segments develops its own shorter term strategy. 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) aggressively 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. 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 market. 55 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 market. More particularly, we believe that our growth initiatives in the wearables market that have been incubated within Materialise Manufacturing may drive growth in the coming years. In the eyewear market, we are investing in back-end production facilities for the production of 3D printed eyewear, including customized frames and also invest in the introduction of advanced front-end digital technologies, such as virtual try-on and fitting solutions, 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, in collaboration with our former joint venture partner, Superfeet. 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, 2022. 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. 56 Table of Contents 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. 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. 57 Table of Contents 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. 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 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. 58 Table of Contents 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. 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 is not 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 discounts. 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)%. 59 Table of Contents 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. 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. From 2017 through September 2020, the total amount capitalized for the U.S. market component of the tracheal splint development project had accumulated to €2.1 million, based on a positive assessment of all recognition criteria. In September 2020, the FDA disapproved the Investigational Device Exemption, or IDE, submission, and in December 2020, the FDA disapproved an amended IDE submission. Our management believes that the technical feasibility of the project (the IDE approval, successful outcome of the clinical trial and obtaining the FDA’s premarket approval, or PMA) remains positive. However, the FDA regulatory process has resulted in a delay of two years compared to our previous assumptions regarding obtaining the PMA and commencing commercialization. As a result, the headroom (defined as the difference between the development expenses capitalized and to be incurred until the PMA is obtained, and the present value of the expected cash flows until 2030 (the year after which the patent would expire)) became negative. Accordingly, in 2020 we concluded that a full impairment of the capitalized expenditures is appropriate for the total amount of €2.1 million. We continued this R&D program during 2022, and aim to obtain the IDE approval from the FDA by mid-2023. 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. 60 Table of Contents 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 2022 and will continue to invest in 2023 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, 2021 we carried in total K€3,871 as assets under construction in respect of these projects. As of December 31, 2022 we carried in total K€6,309 as assets under construction in respect of these 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 has started. 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, 2022, we had current and non-current receivables related to tax credits for an amount of € 5 million (2021: € 5 million; 2020: € 5 million). As of December 31, 2022, we had € 88 million (2021: € 58 million; 2020: € 51 million) of tax losses carried forward and unused Innovation Income Deductions, of which € 45 million related to Materialise NV (2021: € 36 million; 2020: € 28 million). These losses related 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. 61 Table of Contents With respect to the unused tax losses and Innovation Income Deduction of Materialise NV, the deferred tax asset recognized at December 31, 2022 was limited to € 0.2 million (2021: € 0.0 million, 2020: € 0.0 million). Under the Belgian Patent Income Deduction system, companies can deduct up to 85% of their net innovation income from the taxable basis. According our consolidated group’s policy, we have assessed that no additional deferred tax asset should be recognized with respect to our unused tax losses and unused Innovation Income Deductions carried forward in Belgium. With respect to the unused tax losses of the other entities, we recognized at December 31, 2022 a deferred tax asset of € 1.6 million for Materialise USA related to losses carried forward from the acquired entities Link3D and Identify3D. No deferred tax assets were recognized in 2021 and 2020 except for our tax unity in Germany where we recorded a deferred tax asset of € 0.3 million related to 2020 losses, and Materialise Motion where we recorded a deferred tax asset of € 1.8 million against a deferred tax liability of € 2.0 million. We have not recognized deferred tax assets on unused tax losses and Innovation Income Deduction totaling € 19 million as at December 31, 2022 (2021: € 12 million; 2020: € 23 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 tax losses carried forward and unused Innovation Income Deduction would meet the criteria for recognition, net result for the year would have improved by € 19 million in 2022 through a deferred tax benefit. This would represent the planned recovery of € 75 million carried forward tax losses and Innovation Income Deduction in future periods. Further details on taxes are disclosed in Note 22.10 to our consolidated financial statements. Impairment of Goodwill, Intangible Assets and Property, Plant & Equipment We have goodwill for a total amount of € 44.2 million as of December 31, 2022 (2021: € 18.7 million; 2020: € 18.6 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. In 2020 an impairment was recognized on the Engimplan CGU. It was concluded that the value in use was lower than the carrying value of the CGU of € 9.3 million which resulted in a full impairment of the goodwill for an amount of € 1.4 million as well as a partial impairment on intangible assets of customer lists and trade marks for respectively € 0.9 million and € 0.2 million. The key events that led to the impairment loss for the Engimplan CGU were a loss of business resulting from the ongoing COVID-19 pandemic and a slower recovery from the pandemic than expected, and a slower than expected benefit from the anticipated synergies of the Engimplan acquisition. The 2022 impairment exercise showed no further impairment on intangible assets, nor a reversal of impairment. In 2021 we recorded a goodwill impairment of € 0.2 million on the CGU Metal in Belgium, formerly the company Aldema BV. We acquired all shares and voting rights of Aldema BV in 2015 for € 0.1 million. With the creation of the Materialise Metal Competence Center in Bremen, Germany, the recoverable amount of this asset decreased to zero. When events or changes in circumstances indicate that the carrying amount of the intangible assets and property, plant & 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 2022 were € 0.0 million (€ 0.1 million in 2021 and € 4.6 million in 2020). 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. 62 Table of Contents 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 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 account for the convertible loan granted to FluidDa in January 2019, with a notional amount of € 2.5 million, at fair value. The carrying value of the convertible loan amounts to € 3.5 million at December 31, 2022. FluidDa is a private start-up company which offers turnkey contract research services for drug development and medical device development. FluidDa is currently loss-making. In determining the fair value of the convertible loan, we consider different contractual parameters such as the repayment and conversion scenarios and dates. In addition, we must make 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 will determine the conversion factor. The convertible loan has a duration of seven years with a 10% annual interest rate which is capitalized. We have applied a discount factor of 12.67% that is 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. At December 31, 2022 the carrying value of the convertible loan amounted to € 3.5 million which reflected a € 0.3 million downward remeasurement to fair value recognized in financial expenses in 2022. Changes in significant assumptions may lead to a significant increase or decrease in the fair value of the convertible loan. 63 Table of Contents Changes in useful life for certain assets We review the useful life for the intangible assets and property, plant and equipment on an annual basis considering the current facts and circumstances available. This review has not resulted in 2022 in a re-assessment of the useful life for certain specific assets in the categories buildings, fixtures, vehicles and machinery. We refer to Note 7 to our audited consolidated financial statements. 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.

Revenue generated throughout the Americas increased by € 11.5 million, or 15.2%, in the year ended December 31, 2022, compared to the year ended December 31, 2021. In the Americas, revenue for the Materialise Medical segment and for the Materialise Software segment increased and revenue for the Materialise Manufacturing segment remained consistent. Revenue generated in Asia-Pacific increased by € 0.4 million, or 2.2%, in the year ended December 31, 2022, compared to the year ended December 31, 2021, as revenue increased within our Materialise Medical and Materialise Manufacturing segment and decreased within our Materialise Software segment in this region. During 2022, we had increased revenue in all three of our segments compared to 2021. Revenue from our Materialise Software segment increased € 0.8 million, or 1.8%, from € 42.9 million in the year ended December 31, 2021, to € 43.7 million in the year ended December 31, 2022. Recurrent revenue, consisting of limited license fees and maintenance fees, increased by € 4.6 million, or 19.7%, in the year ended December 31, 2022. Non-recurrent revenue, mainly consisting of perpetual fees and services, decreased by € 3.8 million, or 19.0%, in the year ended December 31, 2022. Deferred revenue from license and maintenance fees amounted to € 2.7 million in the year ended December 31, 2022, compared to € 1.9 million in the year ended December 31, 2021. Revenue from our Materialise Medical segment increased € 11.5 million, or 15.6%, from € 73.4 million in the year ended December 31, 2021, to € 84.8 million in the year ended December 31, 2022. Within our medical software department recurrent revenue from annual and renewed licenses and maintenance fees increased by € 3.9 million, or 20.8%, reflecting the implementation of our continued strategy focused on products with defined contractual periods. These recurrent revenues represented 84.8% of all medical software revenues in the year ended December 31, 2022, compared to 83.0% in the year ended December 31, 2021. Our non-recurrent revenue from perpetual licenses and services increased by € 0.3 million, or 6.7%. Deferred revenue from license and maintenance fees amounted to € 5.1 million in the year ended December 31, 2022, compared to € 2.0 million in the year ended December 31, 2021. Revenues from medical devices and services grew by € 7.3 million, or 14.4%, in the year ended December 31, 2022, driven by growth in our CMF business line. As of December 31, 2022, our Materialise Medical segment operated 49 3D printers, as compared to 48 as of December 31, 2021. Revenue from our Materialise Manufacturing segment increased € 14.3 million, or 16.0%, from € 89.2 million in the year ended December 31, 2021, to € 103.5 million in the year ended December 31, 2022. Materialise Manufacturing operated 156 3D printers, 22 CNC machines and 6 vacuum casting machines as of December 31, 2022, compared to 153 3D printers, 23 CNC machines and 6 vacuum casting machines as of December 31, 2021, respectively. Cost of sales. Cost of sales was € 103.3 million in the year ended December 31, 2022, compared to € 87.3 million in the year ended December 31, 2021, representing an increase of € 16.0 million, or 18.3%. This increase in cost of sales was related to increased sales volumes, increased subcontracting volumes and prices, and the impact of inflation related to energy, materials and compensation expenses. Gross profit. Gross profit increased € 10.6 million from € 118.2 million in the year ended December 31, 2021, to € 128.8 million in the year ended December 31, 2022, mainly driven by increased revenue in all three Materialise segments, while facing higher production costs. The overall gross profit margin (gross profit divided by our revenue) amounted to 55.5% in the year ended December 31, 2022, compared to 57.5% in the year ended December 31, 2021. 65 Table of Contents 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 € 134.8 million in the year ended December 31, 2022, compared to € 109.4 million in the year ended December 31, 2021. R&D expenses increased from € 26.9 million to € 37.6 million, or 39.7%, and included the accelerated investments in our Materialise Software CO-AM business which contained the expenditures of Link3D and Identify3D since their acquisition. S&M expenses increased from € 49.2 million to € 62.1 million, or 26.4%, driven by our Materialise Software segment, including severance pay. G&A expenses increased from € 33.3 million to € 35.1 million, or 5.5%. The G&A expenses included the roll-out of our ongoing internal digital transformation project. Net other operating income. Net other operating income decreased to € 3.2 million, or 6.6%, in the year ended December 31, 2022, compared to € 3.4 million in the year ended December 31, 2021. The main driver for this decrease were the amortization expenses of the acquired intangible assets, which represented an expense of € 5.1 million for the year ended December 31, 2022, compared to € 2.5 million for the year ended December 31, 2021. This result for the year ended December 31, 2022 also contained an impairment loss related to capitalized development expenditure in the Materialise Software segment. These expenses were partly offset by a COVID-19 grant received by our German subsidiaries (€ 0.7 million) and a commercial indemnity fee (€ 0.5 million). Our net other operating income for 2021 included a € 0.2 million impairment loss on the goodwill from the acquisition of Aldema (Metal Belgium) in 2015. Net financial income (financial income and financial expense). Net financial income was € 1.7 million in the year ended December 31, 2022, compared to a net income of € 1.5 million in the year ended December 31, 2021. In both years the net positive result was mainly due to positive foreign exchange differences, partially offset by interest expenses on our loans and borrowings. Income taxes. Income taxes in the year ended December 31, 2022 resulted in an expense of € 1.0 million, which was a combination of deferred tax income amounting to € 1.0 million and current income tax expenses of € 2.0 million. This increase in current income tax expense compared to the prior year was mainly due to the fact that mark-ups and margins applied under our consolidated group’s transfer pricing arrangements were still temporarily waived during the first half year of 2021. Net profit/loss. As a result of the factors described above, net loss amounted to € 2.2 million in the year ended December 31, 2022 compared to a net profit of € 13.1 million in the year ended December 31, 2021. Other Financial Information We believe EBITDA and Adjusted EBITDA are meaningful measures to our investors to enhance their understanding of our financial performance. Although EBITDA and Adjusted EBITDA are not necessarily a measure of our ability to fund our cash needs, we understand that it is frequently used by securities analysts, investors and other interested parties as a measure of financial performance and to compare our performance with the performance of other companies that report EBITDA or Adjusted EBITDA. Management believes these non-IFRS measures to be important measures as they exclude the effects of items which primarily reflect the impact of long-term investment and financing decisions, rather than the performance of our day-to-day operations. As compared to net profit, these measures are limited in that they do not reflect the periodic costs of certain capitalized tangible and intangible assets used in generating revenues in our business, or the charges associated with impairments. Management evaluates such items through other financial measures such as capital expenditures and cash flow provided by operating activities. We believe that these measurements are useful to measure a company’s ability to grow or as a valuation measurement. Our calculation of EBITDA and Adjusted EBITDA may not be comparable to similarly titled measures reported by other companies. We calculate EBITDA as net profit (loss) plus income tax expense / (benefit), financial expenses (less financial income), depreciation and amortization, and share in loss of joint venture. We calculate Adjusted EBITDA by adding share-based compensation expenses, acquisition-related expenses of business combinations, impairments and re-valuation of fair value due to business combinations to EBITDA. Disclosure in this annual report of EBITDA 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. EBITDA and Adjusted EBITDA should not be considered as alternatives to net profit or any other performance measure derived in accordance with IFRS. Our presentation of EBITDA and Adjusted EBITDA should not be construed to imply that our future results will be unaffected by unusual or non-recurring items. 66 Table of Contents Reconciliation of Net Profit to Adjusted EBITDA (unaudited) on a Consolidated Basis in 000€ Net profit (loss) Income tax expense / (benefit) Financial expenses Financial income Depreciation and amortization Share in loss of joint venture EBITDA (unaudited) Share-based compensation expenses(1) Acquisition-related expenses of business combinations(2) Impairments(3) Re-valuation of 50% Materialise Motion interest (4) Adjusted EBITDA (unaudited) For the year ended December 31, 2021 13,145 591 4,101 (5,620) 20,516 — 32,733 (833) 413 177 — 32,490 2022 (2,153) 975 4,420 (6,114) 22,026 — 19,154 (140) — — — 19,014 2020 (7,193) (1,028) 5,995 (2,452) 19,775 39 15,137 1,344 63 4,606 (770) 20,380 (1) Share-based compensation expenses represent the cost of equity-settled and cash-settled share-based payments to employees.

(4) Represents a positive revaluation of our initial 50% interest in Materialise Motion after our acquisition of the remaining interest in the joint venture. EBITDA. As a result of the factors described above, our consolidated EBITDA was € 19.2 million in the year ended December 31, 2022, compared to € 32.7 million in the year ended December 31, 2021, a decrease of € 13.6 million. During 2022, we prioritized the sustainability of our revenue growth over the maximization of short term EBITDA. In 2022, revenue increased by 13% and deferred revenues grew by 22%. We continued to strategically invest in our growth businesses despite significant inflationary pressures on labor, energy and materials costs and accelerated the consolidation of both Link3D and Identify3D, as a basis for our future cloud-based recurring income. These added expenses in addition to certain one-time items weighed on the overall profitability of our Adjusted EBITDA for the year, with Adjusted EBITDA decreasing to € 19.0 million.

The decrease in the Adjusted EBITDA margin was a result of our investments to strengthen and accelerate the creation of the Materialise cloud based software platform. Our Materialise Medical segment’s Adjusted EBITDA amounted to € 18.8 million in the year ended December 31, 2022, compared to € 20.7 million in the year ended December 31, 2021. The segment’s Adjusted EBITDA margin decreased to 22.2% in the year ended December 31, 2022 from 28.2% in the year ended December 31, 2021. The decrease in the segment’s Adjusted EBITDA margin was due to our increased investment in research and development to position ourselves for further growth. Our Materialise Manufacturing segment’s Adjusted EBITDA increased to € 8.2 million in the year ended December 31, 2022, from € 6.3 million in the year ended December 31, 2021. The Adjusted EBITDA margin of this segment increased to 8.0% in the year ended December 31, 2022, from 7.0% in the year ended December 31, 2021, as a result of the 16% revenue growth and improved production capacity levels, partly offset by the effects of inflation on compensation, energy and materials expenses.

Revenue from the Materialise Medical segment remained consistent between the year ended December 31, 2021 compared to the year ended December 31, 2020. Revenue generated throughout the Americas increased by € 22.9 million, or 43.5%, in the year ended December 31, 2021 compared to the year ended December 31, 2020. In the Americas, revenue for the Materialise Manufacturing segment and for the Materialise Medical segment increased and revenue for the Materialise Software segment remained consistent. Revenue generated in Asia-Pacific increased by € 2.0 million, or 11.5% in the year ended December 31, 2021 compared to the year ended December 31, 2020, as revenue increased across all three Materialise segments. During 2021, we had increased revenue in all three of our segments compared to 2020. Revenue from our Materialise Software segment increased € 3.8 million, or 9.9%, from € 39.1 million in the year ended December 31, 2020 to € 42.9 million in the year ended December 31, 2021.

Revenue from our Materialise Medical segment increased € 11.6 million, or 18.9%, from € 61.7 million in the year ended December 31,2020 to € 73.4 million in the year ended December 31, 2021. Within our medical software department recurrent revenue from annual and renewed licenses and maintenance fees increased by € 3.6 million, or 23.1%, reflecting the implementation of our continued strategy focused on products with defined contractual periods. These recurrent revenues represented 83.0% of all medical software revenues in the year ended December 31, 2021, compared to 77.0% in the year ended December 31, 2020. Our non-recurrent revenue from perpetual licenses and services decreased by € 0.7 million, or 16.3%. Revenues from medical devices and services grew € 8.8 million, or 21.1% in the year ended December 31, 2021, driven by our CMF business line. As of December 31, 2021, our Materialise Medical segment operated 48 3D printers, as compared to 41 as of December 31, 2020. Revenue from our Materialise Manufacturing segment increased € 19.6 million, or 28.2%, from € 69.6 million in the year ended December 31, 2020 to € 89.2 million in the year ended December 31, 2021. Although the automotive, aerospace and certain other industrial business lines continued to be negatively impacted by the ongoing COVID-19 pandemic (in 2021, particularly during the first half of 2021), all business lines recovered strongly in the second half of 2021 despite remaining below pre-pandemic 2019 levels. However, revenue from the Materialise Motion business line increased € 5.5 million to € 6.3 million in the year ended December 31, 2021, compared to € 0.8 million for the year ended December 31, 2020. Materialise Manufacturing operated 153 3D printers and 6 vacuum casting machines as of December 31, 2021, compared to 147 and 6 as of December 31, 2020, respectively. Cost of sales. Cost of sales was € 87.3 million in the year ended December 31, 2021, compared to € 76.4 million in the year ended December 31, 2020, representing an increase of € 10.9 million, or 14.2%. This increase in cost of sales was mainly related to increased sales volumes. Gross profit. Gross profit increased € 24.2 million from € 94.0 million in the year ended December 31, 2020, to € 118.2 million in the year ended December 31, 2021, mainly driven by increased revenue in all three Materialise segments, and improved production capacity levels and efficiencies. The overall gross profit margin (gross profit divided by our revenue) amounted to 57.5% in the year ended December 31, 2021, compared to 55.2% in the year ended December 31, 2020. 69 Table of Contents 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 € 109.4 million in the year ended December 31, 2021, compared to € 101.1 million in the year ended December 31, 2020. R&D expenses decreased from € 27.1 million to € 26.9 million. Excluding the € 2.1 million impairment charge on our tracheal splint program incurred in 2020, R&D expenses increased 7.5% in 2021. S&M expenses increased from € 44.6 million to € 49.2 million, driven by our Materialise Manufacturing segment, including our eyewear and Materialise Motion business lines. In the aggregate, S&M expenses were € 3.8 million below the pre-pandemic levels of the year ended December 31, 2019, because of continued lower travel expenses and cost containment in general. G&A expenses increased from € 29.3 million to € 33.3 million. The increase in G&A expenses was mainly due to the roll-out of our ongoing internal digital transformation program. Net other operating income. Net other operating income increased to € 3.4 million in the year ended December 31, 2021, compared to € 2.4 million in the year ended December 31, 2020. The 2020 result included the € 2.5 million impairment of goodwill and intangibles related to the Engimplan acquisition of 2019, as a result of the COVID-19 pandemic in Brazil that delayed the roll out of our business plan in that region, including the introduction of 3D printed devices. The 2020 result also included a positive € 0.8 million revaluation of our initial 50% interest in Materialise Motion. The 2021 Net other operating income includes the cost of € 0.2 million impairment of goodwill from the acquisition of Aldema (Metal Belgium) in 2015. Net financial income (financial income and financial expense). Net financial income was € 1.5 million in the year ended December 31, 2021, compared to a net expense of € 3.5 million in the year ended December 31, 2020. This difference of € 5.0 million included a realized exchange gain of € 3.7 million, mainly from positive exchange differences from our USD proceeds on the follow-on offering in June and July of 2021, and € 0.7 million of interest income. Income taxes. Income taxes in the year ended December 31, 2021 resulted in a cost of € 0.6 million, which was a combination of deferred tax income amounting to € 0.7 million and current income tax expenses of € 1.3 million. This income tax cost was mainly due to the growth in revenue, as well as the fact that mark-ups and margins applied under our consolidated group’s transfer pricing arrangements returned to pre-pandemic levels as from July 1, 2021. Net profit. As a result of the elements described above, net profit amounted to € 13.1 million in the year ended December 31, 2021 compared to a net loss of € 7.2 million in the year ended December 31, 2020, or an increase of € 20.3 million.

This segment’s Adjusted EBITDA margin (the segment’s Adjusted EBITDA divided by the segment’s revenue) increased from 34.3% for the year ended December 31, 2020 to 36.8% in the year ended December 31, 2021. The increase in the Adjusted EBITDA margin was a result of the 9.9% growth in revenue, while S&M, R&D and G&A expenditures in the aggregate increased by 5.5%. Our Materialise Medical segment’s Adjusted EBITDA increased from € 13.9 million in the year ended December 31, 2020 to € 20.7 million in the year ended December 31, 2021. The segment’s Adjusted EBITDA margin increased from 22.5% in the year ended December 31, 2020 to 28.2% in the year ended December 31, 2021. The increase in the segment’s Adjusted EBITDA margin was due to the 18.9% growth in revenue, and improved production capacity levels and efficiencies, while S&M, R&D, and G&A expenditures in the aggregate increased 6.1%. The year ended December 31, 2020 included a € 2.1 million impairment charge on our tracheal splint development project. Our Materialise Manufacturing segment’s Adjusted EBITDA increased from € 2.5 million in the year ended December 31, 2020 to € 6.3 million in the year ended December 31, 2021. The Adjusted EBITDA margin of this segment increased from 3.7% in the year ended December 31, 2020 to 7.0% in the year ended December 31, 2021, as a result of the 28% revenue growth, and improved production capacity levels and efficiencies.

From our initial public offering on June 30, 2014 through December 31, 2022, 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. Most recently, on July 6, 2021, we sold 4,600,000 ADSs in a follow-on public offering at a public offering price of $24.00 per ADS, and received net proceeds of approximately $ 105 million. 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. 71 Table of Contents We expect our main uses of cash in the future will be funding our business operations, capital expenditures and loan reimbursements, acquisitions and partnerships. Depending on market conditions, our liquidity requirements, contractual restrictions and other factors, we may also repurchase some of our 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 between October 2022 and April 2025, repayable in full in April 2030. A second draw may be made between October 2022 and June 2025, repayable in full in June 2031. A third and final draw may be made between October 2022 and June 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. Cash Flows The table below summarizes our cash flows from operating activities, investing activities and financing activities for the years ended December 31, 2022, 2021 and 2020. in 000€ Net cash flow from operating activities Net cash flow from/(used in) investing activities Net cash flow from/(used in) financing activities Net increase / (decrease) of cash and cash equivalents Comparison of Years Ended December 31, 2022 and 2021 For the year ended December 31, 2021 25,845 (13,134) 71,156 83,867 2022 22,288 (53,861) (22,510) (54,082) 2020 29,978 (28,265) (16,888) (15,175) Net cash flow from operating activities amounted to € 22.3 million in the year ended December 31, 2022 compared to € 25.8 million in the year ended December 31, 2021, a decrease of € 3.6 million, or 14%. In the year ended December 31, 2022, the net cash flow from operating activities was the result of the income statement cash result of € 21.3 million, decreased by working capital requirements of € 9.2 million, offset by increased deferred revenue of € 10.3 million. Net cash flow used in investing activities was € 53.9 million in the year ended December 31, 2022 compared to € 13.1 million in the year ended December 31, 2021, an increase of € 40.8 million, or 310%, of which € 29.3 million related to the acquisition of Link3D and Identify3D, and € 24.8 million related to capital expenditures. Net cash flow used in financing activities was € 22.5 million in the year ended December 31, 2022, compared to € 71.2 million in net cash flow from financing activities in the year ended December 31, 2021. The positive cash flow in 2021 was driven by the net capital increase € 88.1 million. In 2022, we entered into a new credit facility with KBC, which provides for a € 50 million delayed draw. No drawdowns were made under this new facility in 2022, while our repayment of borrowings and leases amounted to € 21.1 million. Comparison of Years Ended December 31, 2021 and 2020 Net cash flow from operating activities amounted to € 25.8 million in the year ended December 31, 2021 compared to € 30.0 million in the year ended December 31, 2020, a decrease of € 4.1 million, or 14%. The increase in Adjusted EBITDA of € 12.1 million was offset in full by the adverse impact from the revenue growth on our working capital. 72 Table of Contents Net cash flow used in investing activities was € 13.1 million in the year ended December 31, 2021 compared to € 28.3 million in the year ended December 31, 2020, a decrease of € 15.2 million, or 54%. In 2020, in addition to capital expenditures of €17.6 million, cash flow used in investing activities were impacted by the acquisition of our remaining interest in Materialise Motion and convertible loans we granted to Ditto and AM Flow. For more information regarding these loans, see Note 3 to our consolidated financial statements. In 2021, our capital expenditures amounted to € 11.7 million and the convertible loan granted to Ditto of € 3.9 million was fully repaid. We also granted a convertible loan to Link3D for € 2.2 million and purchased an option agreement to acquire Link3D for € 1.7 million. Additionally, PMV, who owned 16.66% of the shares of our subsidiary RapidFit NV, exercised its put option in 2021, resulting in us paying € 0.9 million to acquire this remaining 16.66% of the shares of RapidFit NV. Net cash flow from financing activities was € 71.2 million in the year ended December 31, 2021 compared to € 16.9 million in net cash flow used in financing activities in the year ended December 31, 2020. The positive cash flow in 2021 was driven by the net capital increase € 88.1 million. In 2021, we also did not enter into any new loans or borrowings, while the repayment of borrowings and leases amounted to €18.1 million. Investments in Property, Plant & Equipment and Intangible Assets The table below describes cash paid for investments in property, plant & equipment and intangible assets for the years ended December 31, 2022, 2021 and 2020: in 000€ Purchase of property, plant and equipment Purchase of intangible assets Total Indebtedness For the year ended December 31, 2021 7,934 3,788 11,722 2022 21,608 3,165 24,773 2020 11,032 6,618 17,650 As of December 31, 2022, we had loans and borrowings in the total amount of € 81.0 million, with mainly fixed interest rates.

The duration of the loan will be between six to eight years, and includes a two-year loan repayment grace period. In July 2019, the second tranche of € 25.0 million was drawn. Similar to the first tranche, the duration of the loan will be between six to eight years, and includes a two-year loan repayment grace period. Loans under the contract are made at a fixed rate, based on the Euribor rate at the time of the borrowing, plus a variable margin. The applied rate for the first tranche is initially equal to 2.4%. The applied rate for the second tranche is initially equal to 2.72% and varies in function of certain EBITDA levels and debt ratios. 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 includes a portion of € 18.0 million, repayable monthly over seven years, and a bullet portion of € 10.0 million, payable at once in October 2024. The interest rate is fixed for the duration of the loan, and amounts to 1% on average for both portions. The bank loans are secured with a business pledge mandate, a share pledge on Materialise Germany GMBH, and debt covenants.

In addition, a new investment credit of € 3.0 million was obtained from Commerzbank in June 2018, repayable as from January 2019 and with a fixed interest rate of 1.5%. K€5,000 - Other facility loan A facility loan was contracted in 2012 for the construction of Leuven office and production facilities. The balance of this loan amounted to € 1.9 million as of December 31, 2022. This loan has a repayment schedule of 15 years and interest rate is fixed at 4.61%. Bank investment loans The 20 largest of these investment loans outstanding as of December 31, 2022 amount to a balance of € 8.8 million. They were agreed in 2018, 2017 and prior years to finance various investments in machinery, printers, equipment, and software tools. The vast majority of the loans have a repayment period over seven years, and are at fixed interest rates with weighted average below 1%. 74 Table of Contents K€7,485 Lease liabilities We have had several lease obligations, mainly with financial institutions and related to the financing of buildings and various other items of plant and equipment such as 3D printers.

This loan was repaid in full during the year ended December 31, 2021. Related party loan Ailanthus NV previously granted us a loan at a fixed interest rate of 4.23% that matures in 2025. Prior to the merger between Ailanthus NV and Materialise NV on December 31, 2020, Ailanthus NV was demerged into Lunebeke NV, a newly incorporated company. As a result of this demerger, the loan was transferred from Ailanthus NV to Lunebeke NV. For more information on the merger and related demerger, see “Item 7. Major Shareholders and Related Party Transactions—B. Related Party Transactions.” The purpose of the loan was to finance the purchase of a building in France. The amounts outstanding as of December 31, 2022 were K€96 (2021: K€128; 2020: K€158). The interest expense for the year ended December 31, 2022 was K€5 (2021: K€5; 2020: K€7).

For more information, see “—K€50,000 KBC credit facility” above. Reservation cost for all 3 tranches amounts to 0.15% per year. Transfers from Subsidiaries The amount of dividends payable by our subsidiaries to us is subject to, among other restrictions, general limitations imposed by the corporate laws, capital transfer restrictions and exchange control restrictions of the respective jurisdictions where those subsidiaries are organized and operate. 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, 2022, 2021 and 2020, 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. 75 Table of Contents Contractual Obligations Our contractual commitments will have an impact on our future liquidity.

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. 76 Table of Contents 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. 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. 77 Table of Contents ITEM 6.

(2) Beneficial ownership is determined in accordance with the rules and regulations of the SEC. In computing the number of shares beneficially owned by a person and the percentage ownership of that person, we have included shares that the person has the right to acquire within 60 days of March 21, 2023, including through the exercise of any option, warrant or other right or the conversion of any other security. These shares, however, are not included in the computation of the percentage ownership of any other person.

(3) Consists of (i) 110,545 ordinary shares and 27,135 ADSs held by Mr. Vancraen, (ii) 110,545 ordinary shares and 27,135 ADSs held by Ms. Ingelaere and (iii) 30,858,964 ordinary shares and 1,929,289 ADSs jointly held by Mr. Vancraen and Ms. Ingelaere through Idem, a partnership (maatschap) that is controlled and managed by Mr. Vancraen and Ms. Ingelaere. (4) Based on a Schedule 13G/A filed with the SEC on February 10, 2023 by ARK Investment Management LLC or ARK. ARK is an investment advisor and in the Schedule 13G/A filed by ARK it is reported that ARK has (a) sole voting power with respect to 3,592,979 ADSs; (b) shared voting with respect to 71,296 ADSs; and (c) sole dispositive power with respect to 3,415,360 ADSs. None of our shareholders have different voting rights from other shareholders, except that as long as the Family Shareholders control, directly or indirectly, in the aggregate at least 20% of the voting rights attached to our ordinary shares, a majority of our directors must be appointed by our shareholders from a list of candidates proposed by the Family Shareholders. We are not aware of any arrangement that may, at a subsequent date, result in a change of control of our company. 87 Table of Contents As of March 21, 2023, there were 33 individual holders of record entered in our share register. The number of individual holders of record is based exclusively upon our share register and does not address whether a share or shares may be held by the holder of record on behalf of more than one person or institution who may be deemed to be the beneficial owner of a share or shares in our company. As of March 21, 2023, 53.61% of our outstanding ordinary shares were held directly by 32 holders of record, and we believe that at least 23 of such shareholders (representing 53,60% of our outstanding ordinary shares), are residents of Belgium. As of March 21, 2023, assuming that all of our ordinary shares represented by ADSs are held by residents of the United States, approximately 46.39% of our outstanding ordinary shares were held in the United States by one holder of record, the Bank of New York Mellon, depositary of the ADSs. At such date, there were outstanding 27,399,403 ADSs, each representing one of our ordinary shares, and in the aggregate representing approximately 46.39% of our outstanding ordinary shares. The actual number of holders is greater than these numbers of record holders, and includes beneficial owners whose ADSs are held in street name by brokers and other nominees. This number of holders of record also does not include holder whose shares may be held in trust by other entities. B. Related Party Transactions Since January 1, 2022, there has not been, nor is there currently proposed, any material transaction or series of similar material transactions to which we were or are a party in which any of the members of our board of directors or senior management, holders of more than 10% of any class of our voting securities, or any member of the immediate family of any of the foregoing persons, had or will have a direct or indirect material interest, other than the compensation and shareholding arrangements we describe in “Item 6. Directors, Senior Management and Employees” and “—A. Major Shareholders,” and the transactions we describe below. Lunebeke NV In the past, Ailanthus NV, which was a shareholder of our company up until it was merged into our company (which we refer to as the “Merger”) and which was owned and controlled by Mr. Vancraen and Ms. Ingelaere, had provided several loans and financial leases to us for the purchase of machinery and a portion of our office and production buildings. Ailanthus NV had granted us a loan at a fixed interest rate of 4.23% that matures in 2025. The purpose of the loan was to finance the purchase of a building in France. Prior to the Merger, Ailanthus NV was demerged into Lunebeke NV, a newly incorporated company. All of Ailanthus NV’s assets and liabilities were transferred to Lunebeke NV, with the exception of (i) the ordinary shares of our company held by Ailanthus NV and (ii) the corresponding accounting equity components. As such, the loan granted by Ailanthus NV was also transferred from Ailanthus NV to Lunebeke NV. For additional information about the loan, see Note 15 to our audited consolidated financial statements. We used to rent apartments on a regular basis from Ailanthus NV in order to host our employees from foreign subsidiaries who were visiting our headquarters in Leuven. This activity was also transferred from Ailanthus NV to Lunebeke NV as a result of Ailanthus’s demerger. In 2022, we incurred K€104 of rent expense to Lunebeke NV. Indemnification Agreement In connection with and prior to the Merger, we entered into an indemnification agreement with Ailanthus NV and with Wilfried Vancraen, Hilde Ingelaere and Lunebeke NV (which we refer to collectively as the “indemnifying parties”). Pursuant to the indemnification agreement, among other things, the indemnifying parties agreed to reimburse us for: (i) costs incurred by us in connection with the Merger, (ii) possible liabilities of our company as a result of the Merger, and (iii) possible negative tax consequences, if any, for certain of our shareholders. The obligation to reimburse our shareholders applies to shareholders who were shareholders prior to April 30, 2021 (which we refer to as “qualifying shareholders”). The term of the indemnification agreement expires on December 31, 2030. However, we and any qualifying shareholders have the right to make claims against the indemnifying parties for a period of 10 years following the occurrence giving rise to the claim. 88 Table of Contents Registration Rights Agreement On September 15, 2016, we entered into a registration rights agreement with certain holders of our ordinary shares, warrants and convertible bonds, including certain of our directors, senior management and consultants, which we refer to as the Registration Rights Agreement. In accordance with the terms of the Registration Rights Agreement, we filed a shelf registration statement on Form F-3 registering certain ordinary shares represented by ADSs to be sold by the selling shareholders from time to time. These ordinary shares consisted of ordinary shares previously issued to and ordinary shares issuable upon exercise of warrants or conversion of convertible bonds held by the selling shareholders, as well as ordinary shares underlying ADSs that were acquired by the selling shareholders on the Nasdaq Global Select Market. Letter Agreement Regarding Shares Issuance and Registration Rights In connection with the Merger, we entered into a letter agreement, dated December 31, 2020, with Wilfried Vancraen and Hilde Ingelaere pursuant to which, among other things, we granted certain demand and “piggyback” registration rights to Wilfried Vancraen and Hilde Ingelaere in respect of the new ordinary shares that were issued to them in connection with the Merger. C. Interests of Experts and Counsel Not applicable. ITEM 8. FINANCIAL INFORMATION A. Consolidated Financial Statements and Other Information See “Item 18. Financial Statements.” Legal or Arbitration Proceedings From time to time, we may be subject to various claims or legal or arbitration proceedings that arise in the ordinary course of our business. On November 15, 2021, we received a written notice from counsel for Zimmer Biomet, informing us of Zimmer Biomet’s decision to file a request for arbitration with the Belgian Centre for Arbitration and Mediation. Zimmer Biomet believes that we have a contractual obligation pursuant to the terms of our collaboration to indemnify Zimmer Biomet for the expenses it incurred as a result of its settlement with Conformis, Inc. of a patent dispute. We believe there are meritorious defenses to Zimmer Biomet’s claim and intend to contest it vigorously. However, an adverse resolution of this arbitration could have an adverse effect on our results of operations, financial condition or cash flows in the period in which the arbitration is resolved. No amounts have been accrued for this loss contingency. Other than the litigation described above, we are currently not a party to any other legal or arbitration proceedings, which, in the opinion of our management, is likely to have or could reasonably possibly have a material adverse effect on our business, financial condition or results of operations. Policy on Dividend Distribution We have never declared or paid any cash dividends on our shares, and we have no present intention of declaring or paying any cash dividends in the foreseeable future. Any recommendation by our board of directors to pay cash dividends, subject to compliance with applicable law and any contractual provisions that restrict or limit our ability to pay dividends, including under agreements for indebtedness that we may incur, will depend on many factors, including our financial condition, results of operations, legal requirements, capital requirements, business prospects and other factors that our board of directors deems relevant. All of the shares represented by the ADSs have the same dividend rights as all of our other outstanding shares. In general, distributions of dividends proposed by our board of directors require the approval of our shareholders at a shareholders’ meeting, although our board of directors may declare interim dividends without shareholder approval. 89 Table of Contents 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 Belgian GAAP financial statements. 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. 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. For information regarding the Belgian withholding tax applicable to dividends and related U.S. reimbursement procedures, see “Item 10. Additional Information—E. Taxation—Belgian Taxation.” B. Significant Changes None. ITEM 9. THE OFFER AND LISTING A.

On November 13, 2020, the board of directors increased the share capital of Materialise NV following the exercise of warrants previously issued under the 2013 Warrant Plan, the 2014 Warrant Plan and the 2015 Warrant Plan by € 2,180.98 (excluding an issuance premium of 231,347.86), € 15,212.54 (excluding an issuance premium of € 1,757,042.30) and € 11,324.48 (excluding an issuance premium of € 954,563.02) against the issuance of 115,176, 201,164 and 149,750 new ordinary shares, respectively. On December 31, 2020, in the context of the merger between Materialise NV and Ailanthus NV, the extraordinary general meeting of shareholders decided to increase the share capital of Materialise NV and in the same notarial deed of the same date, decided to decrease the share capital of Materialise NV by the same amount. As a result, the share capital of Materialise NV did not change as a result of the aforementioned merger. On May 5, 2021, the board of directors increased the share capital of Materialise NV following the exercise of warrants previously issued under the 2015 Warrant Plan by € 102,09 (excluding an issuance premium of € 8.605,41) against the issuance of 1.350 new ordinary shares.

C. Material Contracts We have not entered into any material contracts in the prior two years other than in the ordinary course of business and other than those described elsewhere in this annual report, including under “—B. Memorandum and Articles of Association,” “Item 7. Major Shareholders and Related Party Transactions—B. Related Party Transactions.” D. Exchange Controls There are no Belgian exchange control regulations that impose limitations on our ability to make, or the amount of, cash payments to residents of the United States. See “Item 5. Operating and Financial Review and Prospects—B. Liquidity and Capital Resources—Transfers from Subsidiaries” for a discussion of various restrictions applicable to transfers of funds by our subsidiaries. E. Taxation Belgian Taxation The following paragraphs are a summary of material Belgian tax consequences of the ownership of ADSs by an investor. The summary is based on laws, treaties and regulatory interpretations in effect in Belgium on the date of this document, all of which are subject to change, including changes that could have retroactive effect. The summary only discusses Belgian tax aspects which are relevant to U.S. holders of ADSs (“Holders”). This summary does not address Belgian tax aspects which are relevant to persons who are residents in Belgium or engaged in a trade or business in Belgium through a permanent establishment or a fixed base in Belgium. This summary does not purport to be a description of all of the tax consequences of the ownership of ADSs, and does not take into account the specific circumstances of any particular investor, some of which may be subject to special rules, or the tax laws of any country other than Belgium. This summary does not describe the tax treatment of investors that are subject to special rules, such as banks, insurance companies, collective investment undertakings, dealers in securities or currencies, persons that hold, or will hold, ADSs in a position in a straddle, share-repurchase transaction, conversion transactions, synthetic security or other integrated financial transactions. Investors should consult their own advisers regarding the tax consequences of an investment in ADSs in the light of their particular circumstances, including the effect of any state, local or other national laws, double tax treaties and regulatory interpretation thereof. In addition to the assumptions mentioned above, it is also assumed in this discussion that for purposes of the Belgian tax legislation, the owners of ADSs will be treated as the owners of the ordinary shares represented by such ADSs. However, the assumption has not been confirmed by or verified with the Belgian Tax Administration. For the purposes of this summary, ADSs or ordinary shares means ordinary shares represented by ADSs. Both terms are used interchangeably. 92 Table of Contents Belgian Dividend Withholding Tax As a general rule, a Belgian dividend withholding tax of 30% is levied on the gross amount of dividends paid on or attributed to the ordinary shares represented by the ADSs, subject to such relief as may be available under applicable domestic or double tax treaty provisions. Dividends subject to the dividend withholding tax include all benefits attributed to the ordinary shares represented by the ADSs, irrespective of their form. A reimbursement of fiscal capital made in accordance with the Belgian Code of Companies and Associations is partly considered to be a dividend distribution stemming from the existing taxed reserves (irrespective whether incorporated into the capital or not) and/or the tax-free reserves incorporated into the capital. The proportion of the deemed dividend distribution for tax purposes is determined on the basis of the ratio between (A) the sum of (i) certain taxed reserves and (ii) tax-free reserves incorporated into the capital on the one hand and (B) the aggregate of such reserves and the fiscal capital. In principle, fiscal capital includes paid-up statutory share capital, and subject to certain conditions, the paid-up issue premiums and the cash amounts subscribed to at the time of the issue of profit sharing certificates. In case of a redemption by us of own shares represented by ADSs, the redemption distribution (after deduction of the portion of fiscal capital represented by the redeemed shares) will be treated as a dividend which in certain circumstances may be subject to a Belgian dividend withholding tax of 30%, subject to such relief as may be available under applicable domestic or double tax treaty provisions. In case of a liquidation of our Company, any amounts distributed in excess of the fiscal capital will be subject to a 30% dividend withholding tax, subject to such relief as may be available under applicable domestic or double tax treaty provisions. For non-residents, the Belgian dividend withholding tax will be the only tax on dividends in Belgium, unless the non-resident holds ADSs in connection with a business conducted in Belgium, through a fixed base in Belgium or a Belgian permanent establishment. Relief of Belgian Dividend Withholding Tax Under the Belgium-United States Double Tax Treaty (the “Treaty”), there is a reduced Belgian dividend withholding tax rate of 15% on dividends paid by us to a U.S. resident which beneficially owns the dividends and is entitled to claim the benefits of the Treaty under the limitation of benefits article included in the Treaty, (a “Qualifying Holder”). If such Qualifying Holder is a company that owns directly at least 10% of our voting stock, the Belgian dividend withholding tax rate is further reduced to 5%. No Belgian dividend withholding tax is however applicable if the Qualifying Holder, is: (i) a company that is a resident of the United States that has owned directly ADSs representing at least 10% of our capital for a 12-month period ending on the date the dividend is declared, or (ii) a pension fund that is a resident of the United States, provided that such dividends are not derived from the carrying on of a business by the pension fund or through an associated enterprise. Under the normal procedure, we or our paying agent must withhold the full Belgian withholding tax, i.e. 30% (without taking into account the Treaty rate). Qualifying Holders may make a claim for reimbursement for amounts withheld in excess of the rate defined by the Double Tax Treaty. The reimbursement form (Form 276 Div-Aut.) may be obtained from the Centre Etrangers, Team 6, Kruidtuinlaan 50, PO 3429, 1000 Brussels, Belgium or online on the website of the Belgian tax authorities. Qualifying Holders may also, subject to certain conditions, obtain the reduced Treaty rate at source. Qualifying Holders should deliver a duly completed Form 276 Div-Aut. no later than ten days after the date on which the dividend is paid or attributed. U.S. holders should consult their own tax advisors as to whether they qualify for reduction in Belgian withholding tax upon payment or attribution of dividends, and as to the procedural requirements for obtaining a reduced Belgian withholding tax upon the payment of dividends or for making claims for reimbursement. Withholding tax is also not applicable, pursuant to Belgian tax law, on dividends paid to certain U.S. pension funds provided that the U.S. pension fund (i) qualifies as a non-resident saver for Belgian withholding tax purposes (i.e., it has a separate legal personality and fiscal residence outside of Belgium and without a permanent establishment or fixed base in Belgium), (ii) has a corporate purpose that consists solely in managing and investing funds collected in order to pay legal or complementary pensions, (iii) has activity that is limited to the investment of funds collected in the exercise of its statutory purpose, without any profit making activity and (iv) is exempt from income taxes in the United States. Furthermore, such pension fund may not contractually be obligated to redistribute the dividends to any beneficial owner of such dividends for whom it would manage the ADSs nor obligated to pay a manufactured dividend with respect to the ADSs under a securities borrowing transaction (save in certain particular cases as described in Belgian law) and subject to certain procedural formalities. 93 Table of Contents Under Belgian domestic tax law, a dividend withholding tax exemption is available to dividends paid to a non-resident corporate shareholder (located in a Member State of the European Union or in a country with which Belgium has entered in a double tax treaty including sufficient information exchange provisions) provided that (i) at the date of payment or attribution of the dividend it holds a participation in our company representing at least 10% of our share capital, (ii) this holding is held or will be held for an uninterrupted period of at least one year, (iii) this non-resident corporate shareholder is tax resident of the country where it is established according to the tax laws of and the bilateral tax treaties established by such country, (iv) this non-resident corporate shareholder is subject to a corporate income tax regime similar to Belgian corporate income tax regime without benefitting from a tax regime that derogates from the ordinary tax regime and (v) its legal form is (similar to one of the legal forms) listed in the annex of the E.U. directive dated 23 July 1990 (90/435/EC) as amended by the directive of 22 December 2003 (2003/123/EC). This reduced withholding tax will apply provided that certain procedural formalities are complied with. Finally, a dividend withholding tax exemption is available, pursuant to Belgian tax law, to dividends paid to a non-resident corporate shareholder (located in the European Economic Area or in a country with which Belgium has entered in a double tax treaty including sufficient information exchange provisions) to the extent that at the date of payment or attribution of the dividend it holds a participation in our company representing less than 10% of our share capital but the acquisition value of which is at least €2.5 million and provided that certain other conditions are met, i.e., that (i) this holding is held or will be held in full ownership for an uninterrupted period of at least one year (ii) this non-resident corporate shareholder is subject to a corporate income tax regime similar to Belgian corporate income tax regime without benefitting from a tax regime that derogates from the ordinary tax regime, and (iii) its legal form is (similar to one of the legal forms) listed in the annex I, part A, of the E.U. directive dated 30 November 2011 (2011/96/EU) as amended by the directive of 8 July 2014 (2014/86/EU). This reduced withholding tax will apply only if and to the extent that the ordinary Belgian withholding tax cannot be credited or reimbursed to the non-resident corporate shareholder referred to above and subject to certain procedural formalities. Capital Gains and Losses Pursuant to the Belgium-US Double Tax Treaty, capital gains and/or losses realized by a Qualifying Holder from the sale, exchange or other disposition of ADSs do not fall within the scope of application of Belgian tax law. Capital gains realized on ADSs by a corporate Holder which is not entitled to claim the benefits of the Treaty under the limitation of benefits article included in the Treaty are generally not subject to taxation in Belgium unless the corporate Holder is acting through a Belgian permanent establishment or a fixed place in Belgium to which the ADSs are effectively connected. Capital losses are not deductible. Private individual Holders who are not entitled to claim the benefits of the Treaty under the limitation of benefits article included in the Treaty and which are holding ADSs as a private investment will, as a rule, not be subject to tax on any capital gains arising out of a disposal of ADSs. Losses will, as a rule, not be deductible in Belgium. However, if the gain realized by such individual Holders on ADSs is deemed to be realized outside the scope of the normal management of such individual’s private wealth and the capital gain is obtained or received in Belgium, the gain will in principle be taxable at 33% in Belgium if and to the extent that such private individual is actually subject to Belgian non-resident personal tax based on Belgian domestic tax law. The Official Commentary to the Belgian Income Tax Code 1992 stipulates that occasional transactions on a stock exchange regarding ADSs should not be considered as transactions realized outside the scope of normal management of one’s own private wealth. Capital gains realized by such individual Holders on the disposal of ADSs for consideration, outside the exercise of a professional activity, to a non-resident company (or a body constituted in a similar legal form), to a foreign state (or one of its political subdivisions or local authorities) or to a non-resident legal entity who is established outside the European Economic Area, are in principle taxable at a rate of 16.5% in Belgium if, at any time during the five years preceding the sale, such individual Holders has owned directly or indirectly, alone or with his/her spouse or with certain relatives, a substantial shareholding in us (that is, a shareholding of more than 25% of our shares). Capital gains realized by a Holder upon the redemption of ADSs or upon our liquidation will generally be taxable as a dividend. See section “Belgian Dividend Withholding Tax.” 94 Table of Contents Belgian Estate and Gift Tax There is no Belgian estate tax on the transfer of ADSs upon the death of a Belgian non-resident. Donations of ADSs made in Belgium may or may not be subject to gift tax in Belgium depending on the modalities under which the donation is carried out. Belgian Tax on Stock Exchange Transactions A tax on stock exchange transactions (“taxe sur les opérations de bourse” in French / “taks op de beursverrichtingen” in Dutch) is generally levied on the purchase and the sale and on any other acquisition and transfer for consideration of existing ADSs on the secondary market carried out by a Belgian resident investor through a professional intermediary if (i) executed in Belgium through a professional intermediary, or (ii) deemed to be executed in Belgium, which is the case if the order is directly or indirectly made to a professional intermediary established outside of Belgium, either by private individuals having their usual residence in Belgium, or legal entities for the account of their seat or establishment in Belgium. The applicable rate in principle amounts to 0.35% of the consideration paid but with a cap of € 1,600 per transaction and per party. The tax is due separately from each party to any such transaction, i.e., the seller (transferor) and the purchaser (transferee), both collected by the professional intermediary. However, if the intermediary is established outside of Belgium, the tax will in principle be due by the ordering private individual or legal entity, unless that individual or entity can demonstrate that the tax has already been paid. Professional intermediaries established outside of Belgium can, subject to certain conditions and formalities, appoint a Belgian representative for tax purposes, which will be liable for the tax on stock exchange transactions in respect of the transactions executed through the professional intermediary. Belgian non-residents who purchase or otherwise acquire or transfer, for consideration, ADSs in Belgium for their own account through a professional intermediary may be exempt from the tax on stock exchange transactions if they deliver a sworn affidavit to the intermediary in Belgium confirming their non-resident status. No stock exchange tax, nor tax on repurchase transactions is payable by: (i) professional intermediaries described in Article 2, 9° and 10° of the Law of August 2, 2002 acting for their own account, (ii) insurance companies described in Article 2, §1 of the Law of 9 July 1975 acting for their own account, (iii) professional retirement institutions referred to in Article 2, 1° of the Law of October 27, 2006 relating to the control of professional retirement institutions acting for their own account, (iv) collective investment institutions acting for their own account, or (v) regulated real estate companies (for the stock exchange tax only). No stock exchange tax, nor tax on repurchase transactions will thus be due by Holders on the subscription, purchase or sale of ADSs, if the Holders are acting for their own account. In order to benefit from this exemption, the Holders must file with the professional intermediary in Belgium a sworn affidavit evidencing that they are non-residents for Belgian tax purposes. Belgian Annual Tax on Securities Accounts Pursuant to the Law of February 17, 2021 introducing a new annual tax on securities accounts due on securities accounts held through an intermediary if the average value of the taxable financial instruments held on this securities account exceeds €1 million during a reference period of 12 consecutive months. This new annual tax on securities accounts has been introduced because the previous tax on securities accounts was annulled by the Belgian Constitutional Court. The annual tax on securities accounts is due irrespective of whether the holder of a securities account is a physical person or a legal entity. If the holder of a securities account is a Belgian resident, the annual tax on securities accounts will be applicable both to securities accounts held in Belgium as well as securities accounts held abroad. For non-residents, only securities accounts held in Belgium fall in scope of the annual tax on securities accounts. A double tax treaty could prevent Belgium to levy the annual tax on securities accounts. Certain exemptions exist to mitigate the impact of the annual tax on securities accounts on the financial sector. As such, securities accounts held by certain financial undertakings are exempt. 95 Table of Contents All securities held on a securities account are targeted, such as shares, bonds, participations in investment funds and investment companies, but also derived products, such as index trackers, turbo’s, real estate certificates and cash. The rate of the annual tax on securities accounts amounts to 0.15% on securities accounts of which the average value exceeds €1 million during a reference period of 12 consecutive months. In order to avoid that the payment of the tax would result in a decrease of the average value below the €1 million threshold, the rate is limited to 10% of the difference between the taxable base and €1 million in those cases. The reference period is a subsequent period of 12 months starting on October 1 and ending September 30 of the subsequent year or (i) any earlier date when the account is closed; (ii) the moment when the account holder becomes a resident of a state with which Belgium has concluded a tax treaty and the tax treaty allocates the taxing rights to the other state. The average value is calculated by taking the average of the securities accounts values on December 31, March 31, June 30 and September 30. The tax must be declared and paid by the Belgian resident intermediary with whom the securities account is held. If a securities account is held with a non-resident intermediary, the holder of the securities account itself is responsible for the declaration and the payment of the annual tax on securities accounts. Alternatively, the foreign intermediary could also voluntarily appoint a recognized responsible representative in Belgium to declare and pay the tax. In case of non-declaration, late, inaccurate or incomplete declaration, as well as non-payment or late payment, a penalty varying from 10% to 200% of the tax due can be imposed. Every holder of the securities account is jointly and severally liable to pay these penalties. The Law furthermore includes a general anti-abuse provision pursuant to which a rebuttable presumption of tax abuse applies in the following situations: (i) distributing taxable financial instruments over different securities accounts to avoid the threshold of €1 million for an individual account, (ii) converting taxable financial instruments into nominative securities (the latter are out of scope of the tax); and (iii) transferring a securities account to a foreign legal entity which then transfers the securities to a foreign securities account, etc. Prospective Holders should consult their own tax advisors as to whether they are subject to the new annual tax on securities accounts. Proposed EU Financial Transactions Tax On February 14, 2013, the European Commission published a proposal for a Directive for a common financial transactions tax (“FTT”) in Belgium, Germany, Greece, Spain, France, Italy, Austria, Portugal, Slovenia, Estonia and Slovakia (collectively, the “Participating Member States”). The proposed FTT has a very broad scope and could, if introduced in its current form, apply to certain dealings in ADSs in certain circumstances. The FTT could apply in certain circumstances to persons both within and outside of the Participating Member States. Generally, it would apply to certain dealings in ADSs where at least one party is a financial institution, and at least one party is established in a Participating Member State. A financial institution may be, or be deemed to be, “established” in a Participating Member State in a broad range of circumstances, including by transacting with a person established in a Participating Member State. Currently, the proposed FTT remains subject to further negotiations between the Participating Member States. It may therefore be adjusted prior to any implementation, of which the timing and fate remains unclear. Moreover, additional E.U. Member States could decide to participate or drop out of the negotiations. Prospective Holders of ADSs are advised to seek their own professional advice in relation to the FTT. 96 Table of Contents U.S. Taxation The following is a discussion of the material U.S. federal income tax considerations to U.S. holders (as defined below) of acquiring, holding and disposing of the ADSs. The following discussion applies only to U.S. holders that purchase ADSs, will hold ADSs as capital assets for U.S. federal income tax purposes (generally, assets held for investment) and that are not residents of, or ordinarily resident in, Belgium for tax purposes nor hold their ADSs as part of a permanent establishment in Belgium. The discussion also does not address any aspect of U.S. federal taxation other than U.S. federal income taxation. In particular, this summary does not address all tax considerations applicable to investors that own (directly or by attribution) 10% or more of our stock by vote or value, nor does this summary discuss all of the tax considerations that may be relevant to certain types of investors subject to special treatment under the U.S. federal income tax laws (such as financial institutions, insurance companies, real estate investment trusts, regulated investment companies, investors liable for the alternative minimum tax, certain U.S. expatriates, individual retirement accounts and other tax-deferred accounts, partnerships or other pass-through entities for U.S. federal income tax purposes, tax-exempt organizations, dealers in securities or currencies, securities traders that elect mark-to-market tax accounting, investors that will hold the ADSs as part of constructive sales, straddles, hedging, integrated or conversion transactions for U.S. federal income tax purposes or investors whose “functional currency” is not the U.S. dollar). Further, this discussion is limited to U.S. holders that hold our ADSs or ordinary shares as “capital assets” within the meaning of Section 1221 of the Code (generally, property held for investment) at all relevant times and does not address all U.S. federal income tax consequences relevant to a U.S. holder’s particular circumstances, including the impact of the Medicare tax on net investment income. The following summary is based on the U.S. Internal Revenue Code of 1986, as amended (the “Code”), U.S. Treasury Regulations thereunder, published rulings of the U.S. Internal Revenue Service (the “IRS”), the Treaty, and judicial and administrative interpretations thereof, in each case as available on the date of this prospectus supplement. Changes to any of the foregoing, or changes in how any of these authorities are interpreted, may affect the tax consequences set out below, possibly retroactively. No ruling will be sought from the IRS with respect to any statement or conclusion in this discussion, and there can be no assurance that the IRS will not challenge such statement or conclusion in the following discussion or, if challenged, a court will uphold such statement or conclusion. For purposes of the following summary, a “U.S. holder” is a beneficial owner of ADSs that is for U.S. federal income tax purposes: (i) a citizen or individual resident of the United States, (ii) a corporation or other entity treated as a corporation for U.S. federal income tax purposes created or organized in or under the laws of the United States or any state thereof (including the District of Columbia), (iii) an estate, the income of which is subject to U.S. federal income taxation regardless of its source or (iv) a trust if (x) a court within the United States is able to exercise primary supervision over its administration and (y) one or more United States persons (as defined in the Code) have the authority to control all of the substantial decisions of such trust. If a partnership (including any entity treated as a partnership for U.S. federal income tax purposes) holds ADSs, the U.S. federal income tax consequences to the partners of such partnership will depend on the activities of the partnership and the status of the partners. A partnership considering an investment in ADSs, and partners in such partnership, should consult their own tax advisers about the consequences of the investment. We do not expect to be a PFIC, and the discussion under “—Distributions by Us” and “—Proceeds from the Sale, Exchange or Retirement of the ADSs” below assumes we will not be a PFIC. See “—Passive Foreign Investment Company” discussion below. Prospective purchasers of ADSs should consult their own tax advisers with respect to the U.S. federal, state, local and non-U.S. tax consequences to them in their particular circumstances of acquiring, holding, and disposing of, ADSs. Ownership of ADSs in General The discussion below is based, in part, on representations by the Depositary and assumes that each obligation under the deposit agreement and any related agreement will be performed in accordance with its terms. 97 Table of Contents For U.S. federal income tax purposes, an owner of ADSs generally will be treated as the owner of the ordinary shares represented by such ADSs. However, the U.S. Treasury has expressed concerns that parties to whom interests such as the ADSs are delivered in transactions similar to pre-release transactions may be taking actions that are inconsistent with the claiming of foreign tax credits for U.S. holders of ADSs. Accordingly, the analysis of the creditability of Belgian taxes could be affected by actions taken by parties to whom the ADSs are pre-released. No gain or loss will be recognized if you exchange ADSs for the ordinary shares represented by those ADSs. Your tax basis in such ordinary shares will be the same as your tax basis in such ADSs, and the holding period in such ordinary shares will include the holding period in such ADSs. Distributions by Us Subject to the application of the PFIC rules discussed below, the U.S. dollar value of distributions paid by us (including the amount of any taxes withheld) out of its earnings and profits, as determined under U.S. federal income tax principles, will be subject to tax as foreign source ordinary dividend income and will be includible in your gross income upon receipt by the Depositary. However, we do not maintain calculations of its earnings and profits in accordance with U.S. federal income tax accounting principles. U.S. holders should therefore assume that any distribution by us with respect to ordinary shares or ADSs will constitute ordinary dividend income. Subject to applicable limitations, so long as the ADSs are regularly traded on the Nasdaq Global Select Market, we expect that dividends paid by us will be classified as “qualified dividend income” generally subject to tax at lower rates than other items of ordinary income when received by individuals and other non-corporate U.S. holders. Any dividends we pay with respect to the ADSs or ordinary shares will constitute foreign source income for foreign tax credit purposes. The U.S. dollar value of distributions paid by us will be calculated by reference to the exchange rate in effect on the date the dividend distribution is received by the Depositary, regardless of when the Depositary converts the payments into U.S. dollars. If the foreign currency is converted by the Depositary on a later date, a U.S. holder will be required to recognize foreign currency gain or loss in respect of the foreign currency based on the difference between the rate at which it is converted and the rate on the date the dividend was received by the Depositary. Subject to certain limitations, Belgian withholding tax, if any, paid in connection with any distribution with respect to ordinary shares or ADSs may be claimed as a credit against your U.S. federal income tax liability if you elect not to take a deduction for any non- U.S. income taxes for that taxable year otherwise, such Belgian withholding tax may be taken as a deduction . If you are eligible for benefits under the Treaty or are otherwise entitled to a refund for the taxes withheld, you will not be entitled to a foreign tax credit or deduction for the amount of any Belgian taxes withheld in excess of the maximum rate under the Treaty or for the taxes with respect to which you can obtain a refund from the Belgian taxing authorities. As the relevant rules are very complex, you should consult your own tax advisor concerning the availability and utilization of the foreign tax credit or deductions for non-U.S. taxes in your particular circumstances. Proceeds from the Sale, Exchange or Retirement of the ADSs Upon the sale, exchange or retirement of ADSs, a U.S. holder will generally recognize U.S. source capital gain or loss equal to the difference, if any, between the U.S. dollar amount realized on the sale, exchange or retirement and the U.S. holder’s tax basis in the ADSs (generally their cost in U.S. dollars). Any gain or loss generally will be long-term capital gain or loss if the ADSs have been held for more than a year. If you are a non-corporate U.S. holder, including an individual U.S. holder, you may be eligible for reduced U.S. federal income tax rates for long-term capital gains. The deductibility of capital losses is subject to limitations. Gain or loss you recognize on the sale, exchange or retirement of ADSs will generally be treated as U.S. source income or loss for foreign tax credit purposes. 98 Table of Contents Passive Foreign Investment Company We believe that we were not a PFIC for the tax year ended December 31, 2022, and we do not expect to be classified as a PFIC for U.S. federal income tax purposes for the current tax year ending December 31, 2023, or for the foreseeable future. However, PFIC status is a factual determination for each taxable year that cannot be made until after the close of each such year and will depend to a large degree on the market price of our ADSs, which could fluctuate significantly. Therefore, we cannot assure you that we will not be considered a PFIC for the taxable year ended December 31, 2022 or in any subsequent taxable year. If we are a PFIC at any time during the holding period of a U.S. holder, the U.S. holder would be subject to potentially materially greater amounts of tax and subject to additional U.S. tax form filing requirements. In addition, a non-corporate U.S. holder will not be eligible for qualified dividend income treatment on dividends received from us if we are treated as a PFIC for the taxable year in which the dividends are received or for the preceding taxable year. A non-U.S. corporation is a PFIC in any taxable year in which, after taking into account certain look-through rules, either (i) at least 75% of its gross income is passive income or (ii) at least 50% of the average value (determined on a quarterly basis) of its assets is attributable to assets that produce or are held to produce passive income. Passive income generally includes dividends, interest, rents, royalties, gross income from certain commodities transactions, and capital gains. If a non-U.S. corporation owns at least 25% by value of the stock of another corporation, the foreign corporation is treated for purposes of the PFIC tests as owning its proportionate share of the assets of the other corporation, and as receiving directly its proportionate share of the other corporation’s income. The same general look- through rule applies when a foreign corporation owns at least 25% by value of the partnership (a look-through partnership) - the foreign corporation is treated as owning its share of the partnership’s assets and deriving its share of the partnership’s income, characterized as passive or active at the partnership level. In the case the foreign corporation satisfies an “active partner” test, the foreign corporation may treat less-than-25% owned partnerships as look-through partnerships, unless the foreign corporation elects otherwise. Although the determination of whether a non-U.S. corporation is a PFIC for a given taxable year is based on its income and assets for that taxable year, as determined under the PFIC rules, once a non-U.S. corporation is a PFIC for any taxable year, it generally remains a PFIC for any investors that owned interests in all or a portion of such taxable year even if it would not otherwise qualify as a PFIC in later taxable years. We do not undertake to monitor our PFIC status on an ongoing basis. The Code imposes additional taxes on gains from the sale or other disposition of, and “excess distributions” with respect to, shares of a PFIC owned directly (or deemed to be owned directly or indirectly under certain attribution rules) by a U.S. holder. In general, an excess distribution is any distribution to the U.S. holder that is greater than 125% of the average annual distributions received by the U.S. holder (including return of capital distributions) during the three preceding taxable years or, if shorter, the U.S. holder’s holding period for the ADSs. If we were a PFIC in any year in which a U.S. holder held the ADSs (i) the gain or excess distribution would be allocated ratably over the U.S. holder’s holding period for the ADSs, (ii) the amount allocated to the taxable year in which the gain or excess distribution was realized and to any year before we became a PFIC would be taxable as ordinary income, (iii) the amount allocated to each other prior year would be subject to tax at the highest rate in effect for that year and (iv) the interest charge generally applicable to underpayments of tax would be imposed in respect of the tax allocated to each such year. For these purposes, a U.S. holder who uses the ADSs as collateral for a loan would be treated as having disposed of such ADSs. The PFIC rules provide for certain elections that can, in certain circumstances, alter the tax consequences of PFIC status as generally described above, thereby mitigating the adverse tax consequences that generally apply under the PFIC rules as described above. One such election, the “qualified electing fund” or “QEF” election, allows a U.S. holder to include in income its share of the corporation’s income on a current basis and it requires (among other things) that the U.S. holder include with its U.S. federal income tax return a “PFIC Annual Information Statement” provided by the foreign corporation and disclosing to the U.S. Holder its pro rata share of the corporation’s “ordinary earnings” and “net capital gain” as determined under U.S. federal income tax principles. A QEF election also can, in certain circumstances, cause the “excess distribution” regime described above not to apply, generally resulting in more favorable tax consequences upon receipt of PFIC excess distributions or the recognition of gain on sale of PFIC shares (or ADSs). However, we do not intend to calculate our “ordinary earnings” or “net capital gain,” nor do we intend to supply U.S. holders with the required “PFIC Annual Information Statement.” Therefore, it generally will not be possible for you to make a QEF election if we are, or if we become, a PFIC. 99 Table of Contents A different election, the “mark-to-market” election could be available if our ADSs or ordinary shares, as applicable, are considered “marketable stock” as defined under applicable U.S. Treasury Regulations. This election can be made if the ADSs are considered to be “marketable securities” for purposes of the PFIC rules. The ADSs should be marketable securities for these purposes to the extent they are “regularly traded” on the Nasdaq Global Select Market. Generally, shares are treated as “regularly traded” in any calendar year in which more than a de minimis quantity of the shares are traded on a qualified exchange on at least 15 days during each calendar quarter. Subject to certain limitations, a U.S. holder that makes a valid mark-to-market election with respect to the ADSs would be required to take into account the difference, if any, between the fair market value at the end of each taxable year and the fair market value at the end of the preceding taxable year (or the acquisition price in the first year the election is in effect) of those ADSs, as ordinary income or ordinary loss (but only to the extent of the net amount previously included as income by the U.S. holder as a result of the mark-to-market election). A U.S. holder’s basis in the ADSs will be increased by the amount of any ordinary income inclusion and decreased by the amount of any ordinary loss taken into account under the mark-to-market rules. Gains from an actual sale or other disposition of the ADSs for which this election has been properly made would be treated as ordinary income, any losses incurred on a sale or other disposition of the ADSs would be treated as an ordinary loss to the extent of any net mark-to-market gains for prior years and any additional loss would be capital loss. Even if a valid mark-to-market election is made with respect to the ADSs, there is a significant risk that indirect interests in any of our subsidiaries that are PFICs will not be covered by this election but will be subject to the excess distribution rules described above. Under these rules, distribution from, and dispositions of interests in, these subsidiaries, as well as certain other transactions, generally will be treated as a distribution or disposition subject to the discussion above regarding excess distributions. Prospective U.S. holders are urged to consult their own tax advisers about the consequences of holding the ADSs if we are considered a PFIC in any taxable year, including the availability of the mark-to-market election, and whether making the election would be advisable in their particular circumstances. In particular, U.S. holders should consider carefully the impact of a mark-to-market election with respect to their ADSs given that there is a significant risk that we will have subsidiaries that are classified as PFICs. Medicare Tax Certain U.S. holders who are individuals, estates and trusts will be required to pay an additional 3.8% tax on some or all their “net investment income,” which generally includes its dividend income and net gains from the disposition of the ADSs. U.S. holders should consult their own tax advisors regarding the applicability of this additional tax on their particular situation. Information Reporting and Backup Withholding Information returns may be filed with the IRS in connection with distributions on the ADSs and the proceeds from the sale or other disposition of the ADSs unless a U.S. holder establishes that it is exempt from the information reporting rules. A U.S. holder may be subject to backup withholding on these payments if it fails to provide its tax identification number to the paying agent and comply with certain certification procedures. The amount of any backup withholding from a payment to a U.S. holder will be allowed as a credit against its U.S. federal income tax liability and may entitle the U.S. holder to a refund, provided that the required information is timely furnished to the IRS. Tax Return Disclosure Requirement U.S. federal income tax law requires certain U.S. investors to disclose information relating to investments in securities of a non- U.S. issuer. Failure to comply with applicable disclosure requirements could result in the imposition of substantial penalties. U.S. holders should consult their own tax advisors regarding any disclosure obligations. F. Dividends and Paying Agents Not applicable. G. Statement by Experts Not applicable. 100 Table of Contents H. Documents on Display We previously filed with the SEC our registration statement on Form F-1 (Registration No. 333-194982), as amended, and our registration statement on Form F-3 (Registration No. 333-258949), including the prospectuses contained therein, to register our ordinary shares. We have also filed with the SEC a related registration statement on F-6 (Registration No. 333-196734) to register the ADSs. We are subject to the periodic reporting and other informational requirements of the Exchange Act as applicable to foreign private issuers. Our annual reports on Form 20-F are due within four months after each fiscal year end. We are not required to disclose certain other information that is required from U.S. domestic issuers. Also, as a foreign private issuer, we are exempt from the rules of the Exchange Act prescribing the furnishing of proxy statements to shareholders and our directors, senior management and principal shareholders are exempt from the reporting and short-swing profit recovery provisions contained in Section 16 of the Exchange Act. Our SEC filings, including the registration statement, are available to you on the SEC’s website at http://www.sec.gov. We have filed our restated articles of association and all other deeds that are to be published in the annexes to the Belgian State Gazette with the clerk’s office of the Commercial Court of Leuven (Belgium), where they are available to the public. A copy of our restated articles of association is also publicly available as an exhibit to this annual report, as well as on the website of the Royal Federation of Belgian Notaries (only in Dutch, French or German, https://statuten.notaris.be/costa_v1/enterprises/search). This website address is included in this annual report as an inactive textual reference only, and the information and other content appearing on this website are not incorporated by reference into this annual report. In accordance with Belgian law, we must prepare audited annual statutory and consolidated financial statements. The audited annual statutory and consolidated financial statements and the reports of our board and statutory auditor relating thereto are filed with the Belgian National Bank, where they are available to the public. I. Subsidiary Information Not applicable. ITEM 11. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK 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, 2022, 2021 and 2020, 39%, 35% and 35% 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 € 0.9 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 € 0.7 million lower, excluding the effect of the cash and term accounts held in U.S. dollars. 101 Table of Contents To limit the exposure to foreign currency rate fluctuations on the British pound and Japanese yen, we have entered into currency rate swaps as of 2017. Additionally, we are exposed to credit risk, liquidity risk and challenges related to capital management. Inflation Risk We transact business globally and are subject to risks associated with rising inflation. The risk exists that if inflation increases to levels that our selling prices cannot be aligned timely to offset the increase in cost of compensation, materials, services, energy, and capital expenditures. For the first time since the global financial crisis in 2008, inflation in several of our main markets has increased by more than 5% in the year ended December 31, 2022. Although we succeeded in increasing our selling prices in various business lines, we experienced negative effects where cost increases could not be offset completely or timely by selling pricing adjustments. If inflation continues to increase, it may continue to adversely affect our results of operations and financial condition. 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, 2022, we had cash and cash equivalents of € 140.9 million, while €20.0 million of our € 81.0 million gross debt was short term. At December 31, 2022, we had an undrawn 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, 2022, 2021 and 2020. 102 Table of Contents ITEM 12. DESCRIPTION OF SECURITIES OTHER THAN EQUITY SECURITIES A. Debt Securities Not applicable. B. Warrants and Rights Not applicable. C. Other Securities Not applicable. D. American Depositary Shares Bank of New York Mellon serves as the depositary for the ADSs. Each ADS represents one ordinary share (or a right to receive one ordinary share) deposited with the principal Amsterdam office of ING Securities Services, Inc., as custodian for the depositary. Each ADS also represents any other securities, cash or other property which may be held by the depositary. The depositary’s corporate trust office at which the ADSs are administered is located at 240 Greenwich Street, New York, New York 10286. The Bank of New York Mellon’s principal executive office is located at 240 Greenwich Street, New York, New York 10286. A deposit agreement among us, the depositary and the ADS holders sets out the ADS holder rights as well as the rights and obligations of the depositary. New York law governs the deposit agreement and the ADSs. A copy of the deposit agreement is incorporated by reference as an exhibit to this annual report on Form 20-F. 103 Table of Contents Pursuant to the terms of the deposit agreement, you, as an ADS holder, will be required to pay the following fees to the depositary: Persons depositing or withdrawing ordinary shares or ADS holders For: must pay to the depositary: $5.00 (or less) per 100 ADSs (or portion of 100 ADSs) Issuance of ADSs, including issuances resulting from a distribution of ordinary shares or rights or other property Cancellation of ADSs for the purpose of withdrawal, including if the deposit agreement terminates $0.05 (or less) per ADS Any cash distribution to you A fee equivalent to the fee that would be payable if securities distributed to you had been ordinary shares and the shares had been deposited for issuance of ADSs Distribution of securities distributed to holders of deposited securities which are distributed by the depositary to you $0.05 (or less) per ADS per calendar year Depositary services Registration or transfer fees Expenses of the depositary Transfer and registration of ordinary shares on our share register to or from the name of the depositary or its agent when you deposit or withdraw shares Cable, telex and facsimile transmissions (when expressly provided in the deposit agreement) converting foreign currency to U.S. dollars Taxes and other governmental charges the depositary or the custodian has to pay on any ADS or ordinary shares underlying an ADS, such as share transfer taxes, stamp duty or withholding taxes As necessary Any charges incurred by the depositary or its agents for servicing the As necessary deposited securities The depositary collects its fees for delivery and surrender of ADSs directly from investors depositing ordinary shares or surrendering ADSs for the purpose of withdrawal or from intermediaries acting for them. The depositary collects fees for making distributions to investors by deducting those fees from the amounts distributed or by selling a portion of distributable property to pay the fees. The depositary may collect its annual fee for depositary services by deduction from cash distributions or by directly billing investors or by charging the book-entry system accounts of participants acting for them. The depositary may collect any of its fees by deduction from any cash distribution payable to ADS holders that are obligated to pay those fees. The depositary may generally refuse to provide fee-based services until its fees for those services are paid. From time to time, the depositary may make payments to us to reimburse or share revenue from the fees collected from ADS holders, or waive fees and expenses for services provided, generally relating to costs and expenses arising out of establishment and maintenance of the ADS program. In performing its duties under the deposit agreement, the depositary may use brokers, dealers or other service providers that are affiliates of the depositary and that may earn or share fees or commissions. 104 Table of Contents ITEM 13.

CONTROLS AND PROCEDURES a) Disclosure Controls and Procedures Our management, with the participation of our Chief Executive Officer and our Chief Financial Officer, evaluated the effectiveness of our disclosure controls and procedures as of December 31, 2022. The term “disclosure controls and procedures,” as defined in Rules 13a-15(e) and 15d-15(e) under the Exchange Act, means controls and other procedures of a company that are designed to ensure that information required to be disclosed by a company in the reports that it files or submits under the Exchange Act is recorded, processed, summarized and reported, within the time periods specified in the SEC’s rules and forms. Disclosure controls and procedures include, without limitation, controls and procedures designed to ensure that information required to be disclosed by a company in the reports that it files or submits under the Exchange Act is accumulated and communicated to the company’s management, including its principal executive and principal financial officers, as appropriate to allow timely decisions regarding required disclosure. Management recognizes that any controls and procedures, no matter how well designed and operated, can provide only reasonable assurance of achieving their objectives and management necessarily applies its judgment in evaluating the cost benefit relationship of possible controls and procedures. Based on this evaluation, management concluded as of December 31, 2022, that our disclosure controls and procedures were effective. b) Management’s Annual Report on Internal Control over Financial Reporting Our management is responsible for establishing and maintaining adequate internal control over financial reporting as defined in Rules 13a-15(f) and 15d-15(f) under the Exchange Act. Our internal control over financial reporting is a process designed by, or under the supervision of, our Chief Executive Officer and Chief Financial Officer and effected by our management and other personnel to provide reasonable assurance regarding the reliability of our financial reporting and the preparation of our financial statements for external reporting purposes in accordance with IFRS. Internal control over financial reporting includes policies and procedures that pertain to the maintenance of records that in reasonable detail accurately and fairly reflect the transactions and dispositions of our assets; provide reasonable assurance that transactions are recorded as necessary to permit preparation of our financial statements in accordance with generally accepted accounting principles, and that our receipts and expenditures are being made only in accordance with the authorization of our board of directors and management; and provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use or disposition of our assets that could have a material effect on our financial statements. Because of its inherent limitations, internal control over financial reporting may not prevent or detect all misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with our policies and procedures may deteriorate. Management assessed the effectiveness of our internal control over financial reporting as of December 31, 2022 using the criteria set forth by the Committee of Sponsoring Organizations of the Treadway Commission in the Internal Control-Integrated Framework, 2013 (the “COSO 2013 Framework”). 105 Table of Contents Based on its assessment, our management, including our Chief Executive Officer and our Chief Financial Officer, has concluded that our internal control over financial reporting was effective as of December 31, 2022. c) Attestation Report of the Registered Public Accounting Firm The effectiveness of internal control over financial reporting as of December 31, 2022 has been audited by KPMG Bedrijfsrevisoren BV / KPMG Réviseurs d’Entreprises SRL, our independent registered public accounting firm. Their audit report, including their opinion on management’s assessment of internal control over financial reporting, is included with our consolidated financial statements in this Form 20-F. d) Changes in Internal Control over Financial Reporting Following the identification of material weaknesses in internal control over financial reporting in Management’s Annual Report as at December 31, 2021, we implemented a remediation plan. This plan included in particular the remediation of our monitoring processes to assess the consistent operation of internal controls over financial reporting. We have further strengthened our compliance functions and control ownership functions, and we have allocated additional resources to the testing of the key controls within our framework of internal control over financial reporting. Through the remediation plan, the material weakness identified as at December 31, 2021 has been remediated as of December 31, 2022. Other than as discussed above, there were no changes in our internal control over financial reporting that occurred during the period covered by this report that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting. ITEM 16A. AUDIT COMMITTEE FINANCIAL EXPERT Our board of directors has determined that each of the members of our audit committee, Johan De Lille, Jürgen Ingels and Bart Luyten, is an “audit committee financial expert” as defined in Item 16A of Form 20-F under the Exchange Act and is independent under Rule 10A-3 under the Exchange Act. ITEM 16B. CODE OF ETHICS We have adopted a written code of conduct and ethics that outlines the principles of legal and ethical business conduct under which we do business. The code of conduct and ethics applies to all of our directors, senior management, consultants and other employees, including our Chief Executive Officer and Chief Financial Officer. We have posted this code of conduct and ethics on our website at www.materialise.com. This website address is included in this annual report as an inactive textual reference only, and the information and other content appearing on our website are not incorporated by reference into this annual report.

EXEMPTIONS FROM THE LISTING STANDARDS FOR AUDIT COMMITTEES None. ITEM 16E. PURCHASES OF EQUITY SECURITIES BY THE ISSUER AND AFFILIATED PURCHASERS None. ITEM 16F. CHANGE IN REGISTRANT’S CERTIFYING ACCOUNTANT Not applicable. ITEM 16G. CORPORATE GOVERNANCE The Listing Rules of the Nasdaq Stock Market include certain accommodations in the corporate governance requirements that allow foreign private issuers, such as us, to follow “home country” corporate governance practices in lieu of the otherwise applicable corporate governance standards of the Nasdaq Stock Market. The application of such exceptions requires that we disclose each noncompliance with the Nasdaq Stock Market Listing Rules and describe the Belgian corporate governance practices we do follow in lieu of the relevant Nasdaq Stock Market corporate governance standard. We follow Belgian corporate governance practices in lieu of the corporate governance requirements of the Nasdaq Stock Market in respect of the following: ● Quorum at Shareholder Meetings. Nasdaq Stock Market Listing Rule 5620(c) requires that for any meeting of shareholders, the quorum must be no less than 33% or 1/3 of the outstanding ordinary shares. There is no quorum requirement under Belgian law for our shareholders’ meetings, except as provided for by law in relation to decisions regarding certain matters. 107 Table of Contents ● Independent Director Majority on Board/Meetings. Nasdaq Stock Market Listing Rules 5605(b)(1) and (2) require that a majority of the board of directors must be comprised of independent directors and that independent directors must have regularly scheduled meetings at which only independent directors are present. We are not required under Belgian law to have any independent directors on our board of directors. However, our restated articles of association provide that our board of directors must be comprised of at least seven and no more than 11 directors, of which at least three directors must be independent directors under Belgian law. The Belgian law definition of independence differs from the definition of independence under the Nasdaq Stock Market Listing Rules.We do not intend to require our independent directors to meet separately from the full board of directors on a regular basis or at all although the board of directors is supportive of its independent members voluntarily arranging to meet separately from the other members of our board of directors. ● Director Nominations/Remuneration and Nomination Committee Composition. Nasdaq Stock Market Listing Rule 5605(d)(2) requires that compensation of officers must be determined by, or recommended to, the board of directors for determination, either by a majority of the independent directors, or a compensation committee comprised solely of independent directors. Nasdaq Stock Market Listing Rule 5605(e) requires that director nominees be selected, or recommended for selection, either by a majority of the independent directors or a nominations committee comprised solely of independent directors. Under Belgian law, we are not subject to any such requirements. In particular, we are not required by Belgian law to set up any compensation or nominations committees within our board of directors, and are therefore not subject to any Belgian legal requirements as to the composition of such committees either. However, our restated articles of association provide that our board of directors may form committees from among its members. See “Item 6. Directors, Senior Management and Employees—C. Board Practices —Board of Directors Practices.” Our board of directors has set up and appointed a Remuneration and Nomination Committee. Our Remuneration and Nomination Committee is currently comprised of three directors, one of whom is independent. In addition, as long as the Family Shareholders control, directly or indirectly, in the aggregate at least 20% of the voting rights attached to our ordinary shares, a majority of our directors must be appointed by our shareholders from a list of candidates proposed by the Family Shareholders. ● Shareholder Approval of Equity Compensation Plans. Nasdaq Stock Market Listing Rule 5635(c) requires shareholder approval prior to the issuance of securities in connection with equity-based compensation of officers, directors, employees or consultants. In lieu of the Nasdaq Stock Market Listing Rule 5635(c), we have historically followed Belgian law regarding the issuance of shares or securities in connection with the remuneration of the directors and/or the employees of a Belgian company. Under Belgian company law, a Belgian company may issue shares or grant rights to acquire shares pursuant to a resolution of the general meeting of shareholders or, within certain limits, pursuant to a resolution of the board of directors if so authorized by the shareholders’ meeting (the so-called authorized capital). By resolution of our extraordinary shareholders’ meeting of November 5, 2020, which entered into force on November 9, 2020, our shareholders authorized our board of directors, for a period of five years from November 9, 2020, to increase our share capital, in one or more transactions (including through the issuance of warrants), up to a maximum amount of € 4,067,700.72. The board of directors is authorized to limit or cancel the preferential subscription right of current shareholders (for example, when it decides to issue warrants), if this is in the interest of our company. The board of directors can do this for the benefit of one or more specific persons, even if these persons are not personnel of our company or our subsidiaries. Pursuant to this authorization, our board of directors may determine to adopt other equity-based compensation plans for our officers, directors, employees or consultants. ITEM 16H.

We also have audited the Company’s internal control over financial reporting as of December 31, 2022, based on criteria established in Internal Control – Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission. In our opinion, the consolidated financial statements referred to above present fairly, in all material respects, the financial position of the Company as of December 31, 2022 and 2021 and the results of its operations and its cash flows for each of the years in the three-year period ended December 31, 2022, in conformity with International Financial Reporting Standards as issued by the International Accounting Standards Board. Also in our opinion, the Company maintained, in all material respects, effective internal control over financial reporting as of December 31, 2022 based on criteria established in Internal Control – Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission. Basis for Opinions The Company’s management is responsible for these consolidated financial statements, for maintaining effective internal control over financial reporting, and for its assessment of the effectiveness of internal control over financial reporting, included in the accompanying Management’s Annual Report on Internal Control over Financial Reporting in Item 15 (b). Our responsibility is to express an opinion on the Company’s consolidated financial statements and an opinion on the Company’s internal control over financial reporting based on our audits. We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) (PCAOB) and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB. We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audits to obtain reasonable assurance about whether the consolidated financial statements are free of material misstatement, whether due to error or fraud, and whether effective internal control over financial reporting was maintained in all material respects. Our audits of the consolidated financial statements included performing procedures to assess the risks of material misstatement of the consolidated financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the consolidated financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the consolidated financial statements. Our audit of internal control over financial reporting included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, and testing and evaluating the design and operating effectiveness of internal control based on the assessed risk. Our audits also included performing such other procedures as we considered necessary in the circumstances. We believe that our audits provide a reasonable basis for our opinions. F-2 Table of Contents Definition and Limitations of Internal Control Over Financial Reporting A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company’s internal control over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company’s assets that could have a material effect on the financial statements. Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate. Critical Audit Matters The critical audit matters communicated below are matters arising from the current period audit of the consolidated financial statements that were communicated or required to be communicated to the audit committee and that: (1) relate to accounts or disclosures that are material to the consolidated financial statements and (2) involved our especially challenging, subjective, or complex judgments. The communication of critical audit matters does not alter in any way our opinion on the consolidated financial statements, taken as a whole, and we are not, by communicating the critical audit matters below, providing separate opinions on the critical audit matters or on the accounts or disclosures to which they relate. Fair value of software and brands and trademarks acquired in the Link3D business combination As discussed in Note 4 to the consolidated financial statements, the Company acquired 100% of the voting equity interest in Link3D, Inc. (Link3D) on January 4, 2022 for a total purchase price of K€ 26,747. As a result of the acquisition, the Company recognized K€ 6,892 of software and K€ 1,066 of brands and trademarks. We identified the assessment of the fair value of software and brands and trademarks acquired in the Link3D business combination as a critical audit matter. A high degree of subjective auditor judgment and specialized skills and knowledge was required to evaluate the forecasted year-on-year growth rate of revenue, the software royalty rate, the brands and trademarks royalty rate and the discount rate, as changes in these assumptions could cause significant changes in the fair value of the software and the brands and trademarks. The following are the primary procedures we performed to address this critical audit matter. — We evaluated the design and tested the operating effectiveness of an internal control related to the Company’s acquisition- date fair value measurement process of intangible assets including the evaluation of the assumptions for the year-on-year growth rate of revenue, the software royalty rate, the brands and trademarks royalty rate and the discount rate used to determine the acquisition-date fair values. — We evaluated the forecasted year-on-year growth rate of revenue by comparing it to Link3D’s historical performance, and to the forecasts presented to the Company’s board of directors and used by the Company to determine the enterprise value of Link3D. — We also involved valuation professionals with specialized skills and knowledge, who assisted in: ● evaluating the Company’s software royalty rate and brands and trademarks royalty rate, by comparing them to licensing transactions for similar intellectual property; and ● evaluating the Company’s discount rate, by comparing it against a discount rate range that was independently developed using publicly available market data for comparable entities. F-3 Table of Contents Impairment analysis for the Engimplan cash generating unit As discussed in Note 3 to the consolidated financial statements, the Company performs impairment testing on an annual basis and whenever events or changes in circumstances indicate that the carrying amount of a cash generating unit (CGU) may not be recoverable. The Company determined the recoverable amount of the Engimplan CGU based on the value-in-use using a discounted cash flow model. As discussed in Note 5 to the consolidated financial statements, the Company determined that the value-in-use of the Engimplan CGU approximated its carrying value at December 31, 2022. We identified the evaluation of the impairment analysis for the Engimplan CGU as a critical audit matter. A high degree of subjective auditor judgment and specialized skills and knowledge was required to evaluate the Engimplan CGU’s forecasted year- on-year growth rate of revenue and gross margin, perpetual growth rate and the discount rate, as changes in these assumptions could cause significant changes in the value-in-use of the Engimplan CGU. The following are the primary procedures we performed to address this critical audit matter. — We evaluated the design and tested the operating effectiveness of an internal control related to the Company’s impairment process including the evaluation of the assumptions for the year-on-year growth rate of revenue and gross margin, perpetual growth rate and the discount rate used to determine the value-in-use. — We evaluated the year-on-year growth rate of revenue and gross margin by comparing them to the Engimplan CGU’s historical performance. — We assessed management’s ability to accurately forecast by comparing forecasts made by management in the prior year to the actual performance of the Engimplan CGU. — We evaluated the perpetual growth rate by comparing it to the Engimplan CGU’s historical performance and to external market and industry data. — We also involved valuation professionals with specialized skills and knowledge, who assisted in evaluating the Company’s discount rate, by comparing it against a discount rate range that was independently developed using publicly available market data for comparable entities.

Technologielaan 15, 3001 Leuven, Belgium. The consolidated financial statements comprise Materialise NV (the “Company” or “Parent”) and its subsidiaries (collectively, the “Group” or “we,” “us” and “our”). See Note 28 for a list of subsidiaries of the Company. We are a leading provider of additive manufacturing and medical software and of sophisticated 3D printing services. Our products and services are offered through a market oriented organization that is active across three principal market segments: (i) Materialise Software, (ii) Materialise Medical, and (iii) Materialise Manufacturing. We sell our products and services in Europe, the Americas, Africa and Asia-Pacific. The consolidated financial statements of the Group for the year ended December 31, 2022 were approved and authorized for issue on April 17, 2023, in accordance with a resolution of the Company’s board of directors. 2 Basis of preparation The consolidated financial statements of the Group for the three years ended December 31, 2022, 2021 and 2020 are prepared in accordance with the International Financial Reporting Standards (IFRS) as issued by the International Accounting Standards Board (IASB) (collectively “IFRS”). These consolidated financial statements have been prepared on a historical cost basis, except for the assets and liabilities that have been acquired as part of a business combination, which have been initially recognized at fair value, and certain financial assets such as the non-listed equity instruments and the convertible loan receivable which are both included in the other non-current assets and the share appreciation rights are measured at fair value. The financial statements are prepared on a going concern basis. The consolidated financial statements are presented in thousands of euros (K€ or thousands of €) and all “currency” values are rounded to the nearest thousand (€000), except when otherwise indicated. The preparation of financial statements in compliance with IFRS requires the use of certain critical accounting estimates. It also requires Group management to exercise judgment in applying the Group’s accounting policies. The areas where significant judgment and estimates have been made in preparing the financial statements and their effect are disclosed in Note 3. New standards, interpretations and amendments adopted by the Group The following amendments and interpretations issued by the IASB and IFRIC apply for the first time in 2022, but do not have a significant impact on the consolidated financial statements of the Group. — — — — — Amendments to IAS 37 Cost of Fulfilling a Contract (issued on 14 May 2020) Amendments to IAS 16 Property, Plant and Equipment: Proceeds before intended Use (issued on 14 May 2020) Amendments to IFRS 3 Reference to the Conceptual Framework (issued on 14 May 2020) Annual improvements to IFRS Standards 2018-2020 (issued on 14 May 2020) IFRS 9 Financial Instruments Annual Improvements to IFRSs 2018-2020 Cycle: Fees in the ‘10 per cent’ test for derecognition of financial liabilities (issued 2 July 2021) A number of new standards, amendments to standards and interpretations are not yet effective for the year ended 31 December 2022 and have not been applied in preparing these consolidated financial statements. The amendments are not expected to have a material impact on the Group’s consolidated financial statements. Amendments to IAS 1 Presentation of Financial statements: Classification of Liabilities as Current or Non-current, issued on 23 January 2020, clarify a criterion in IAS 1 for classifying a liability as non-current: the requirement for an entity to have the right to defer settlement of the liability for at least 12 months after the reporting period. F-12 Table of Contents The amendments: — — — — specify that an entity’s right to defer settlement must exist at the end of the reporting period; clarify that classification is unaffected by management’s intentions or expectations about whether the entity will exercise its right to defer settlement; clarify how lending conditions affect classification; and clarify requirements for classifying liabilities an entity will or may settle by issuing its own equity instruments. However, the 2020 amendments are subject to future developments. In November 2021, the IASB published exposure draft Non-current Liabilities with Covenants – Proposed amendments to IAS 1, which proposed further amendments to IAS 1 and the deferral of the effective date of the 2020 amendments to no earlier than 1 January 2024. Amendments to IAS 1 Presentation of Financial Statements and IFRS Practice Statement 2: Disclosure of Accounting policies, issued on 12 February 2021, include narrow-scope amendments to improve accounting policy disclosures so that they provide more useful information to investors and other primary users of the financial statements. The amendments to IAS 1 require companies to disclose their material accounting policy information rather than their significant accounting policies. The amendments to IFRS Practice Statement 2 provide guidance on how to apply the concept of materiality to accounting policy disclosures. These amendments are effective for annual periods beginning on or after 1 January 2023 with early application permitted. Amendments to IAS 8 Accounting policies, Changes in Accounting Estimates and Errors: Definition of Accounting Estimates, issued on 12 February 2021, clarify how companies should distinguish changes in accounting policies from changes in accounting estimates. The distinction is important because changes in accounting estimates are applied prospectively only to future transactions and other future events, but changes in accounting policies are generally also applied retrospectively to past transactions and other past events. These amendments are effective for annual periods beginning on or after 1 January 2023 with early application permitted. Amendments to IAS 12 Income Taxes: Deferred Tax related to Assets and Liabilities arising from a Single Transaction, issued on 7 May 2021, clarifies how companies should account for deferred tax on transactions such as leases and decommissioning obligations. IAS 12 Income Taxes specifies how a company accounts for income tax, including deferred tax, which represents tax payable or recoverable in the future. In specified circumstances, companies are exempt from recognizing deferred tax when they recognize assets or liabilities for the first time. Previously, there had been some uncertainty about whether the exemption applied to transactions such as leases and decommissioning obligations—transactions for which companies recognize both an asset and a liability. The amendments clarify that the exemption does not apply and that companies are required to recognize deferred tax on such transactions. The aim of the amendments is to reduce diversity in the reporting of deferred tax on leases and decommissioning obligations. These amendments are effective for annual periods beginning on or after 1 January 2023 with early application permitted. Amendment to IFRS 16 Leases Liability in a Sale and Leaseback On September 22, 2022, the IASB issued Lease Liability in a Sale and Leaseback (Amendments to IFRS 16) with amendments that clarify how a seller-lessee subsequently measures sale and leaseback transactions that satisfy the requirements in IFRS 15 to be accounted for as a sale. These amendments are effective for annual periods beginning on or after 1 January 2024 with early application permitted. F-13 Table of Contents 3 Summary of significant accounting policies Basis for consolidation The consolidated financial statements comprise the financial statements of the Group and its subsidiaries. Entities are fully consolidated from the date of acquisition, which is the date when the Group obtains control, and continue to be consolidated until the date when such control ceases. The financial statements of the entities are prepared for the same reporting period as the parent company, using consistent accounting policies. All intra-Group balances, transactions, unrealized gains and losses resulting from intra-Group transactions and dividends are fully eliminated. The Group attributes profit or loss and each component of other comprehensive income to the owners of the parent company and to the non-controlling interest based on present ownership interests, even if the results in the non-controlling interest have a negative balance. A change in the ownership interest of a subsidiary, without a loss of control, is accounted for as an equity transaction. If the Group loses control over the subsidiary, it will derecognize the assets (including goodwill) and liabilities of the subsidiary, any non-controlling interest and the other components of equity related to the subsidiary. Any surplus or deficit arising from the loss of control is recognized in profit or loss. If the Group retains an interest in the previous subsidiary, then such interest is measured at fair value at the date the control is lost. The proportion allocated to the parent and non-controlling interests in preparing the consolidated financial statements is determined based solely on present ownership interests. On January 4, 2022, the Group acquired full ownership of Link3D, an additive workflow and digital manufacturing software company that supports customers in major manufacturing industries to scale and integrate their AM operations across complex supply chains and IT environments. The acquisition was realized by the Group’s U.S. subsidiary, Materialise USA, LLC by exercising the call option. On October 1, 2022, Link3D and Materialise USA merged. See also Note 4. On September 1, 2022, the Group acquired full ownership of Identify3D, a company that develops software to encrypt, distribute, and trace the flow of digital parts across complex supply chains. The acquisition was realized by the Group’s U.S. subsidiary, Materialise USA, LLC. On December 31, 2022 Identify3D and Materialise USA merged. See also Note 4. Non-controlling interests The Group has the choice, on a transaction by transaction basis, to initially recognize any non-controlling interest in the acquiree which is a present ownership interest and entitles its holders to a proportionate share of the entity’s net assets in the event of liquidation at either acquisition date fair value or, at the present ownership instruments’ proportionate share in the recognized amounts of the acquiree’s identifiable net assets. Other components of non-controlling interest such as outstanding share options are generally measured at fair value. The Group has not elected to take the option to use fair value in acquisitions completed to date. As of December 31, 2021, the only non-controlling interest relates to Tianjin Zhenyuan Materialise Medical Technology Ltd., a subsidiary that Materialise, together with Zhenyuan (Tianjin) Medical Appliances Technology Co., Ltd., incorporated on June 22, 2021. Materialise holds 51% of the shares of this subsidiary. See also Note 4. Foreign currency translation The Group’s consolidated financial statements are presented in euros, which is also the parent company’s functional currency. For each entity, the Group determines the functional currency, and items included in the financial statements of each entity are measured using the functional currency. Financial statements of foreign subsidiaries Foreign subsidiaries use the local currencies of the country where they operate. The statement of financial position is translated into euro at the closing rate on the reporting date and their income statement is translated at the average exchange rate at each month-end. Differences resulting from the translation of the financial statements of said subsidiaries are recognized in other comprehensive income as “exchange differences on translation of foreign operations”. F-14 Table of Contents Foreign currency transactions Transactions denominated in foreign currencies are translated into euro at the exchange rate of the previous day. Monetary items in the statement of financial position are translated at the closing rate at each reporting date and the relevant translation adjustments are recognized in financial or operating result depending on its nature. Business combinations and goodwill Business combinations are accounted for using the acquisition method at the acquisition date, which is the date at which the Group obtains control over the entity. The cost of an acquisition is measured as the amount of the consideration transferred to the seller, measured at the acquisition date fair value, and the amount of any non-controlling interest in the acquiree. The Group measures goodwill initially at cost at the acquisition date, being: ● the fair value of the consideration transferred to the seller, plus ● the amount of any non-controlling interest in the acquiree, plus ● if the business combination is achieved in stages, the fair value of the existing equity interest in the acquiree re-measured at the acquisition date, less ● the fair value of the net identifiable assets acquired and assumed liabilities Goodwill is recognized with any impairment in carrying value being charged to the consolidated income statement. Where the fair value of identifiable assets, liabilities and contingent liabilities exceeds the fair value of consideration paid, the excess is credited in full to the consolidated income statement on acquisition date. Acquisition costs incurred are expensed and included in general and administrative expenses. Any contingent consideration to be transferred by the acquirer will be recognized at fair value at the acquisition date. Subsequent changes to the fair value of the contingent consideration, which is deemed to be an asset or liability, will be recognized in profit or loss. If the contingent consideration is classified as equity, it is not re-measured until it is finally settled within equity. Acquisition of non-controlling interests are accounted for as an equity transaction. Investments in joint ventures At December 31, 2022, Materialise had no investments in joint ventures. Property, plant & equipment Property, plant and equipment is stated at cost, net of accumulated depreciation and/or accumulated impairment losses, if any. Such cost includes borrowing costs directly attributable to construction projects if the asset necessarily takes a substantial period of time to get ready for its intended use, it is probable that they will result in future economic benefits to the Group and the cost can be measured reliably. When significant parts of property, plant and equipment are required to be replaced at intervals, the Group recognizes such parts as individual assets with specific useful lives and depreciates them accordingly. Likewise, when a major inspection is performed, its cost is recognized in the carrying amount of the property, plant and equipment as a replacement if the recognition criteria are satisfied. All other repair and maintenance costs are recognized in the income statement as incurred. Depreciation is calculated on a straight-line basis over the estimated useful lives of the assets as follows: ● Buildings: ● Machinery: ● IT assets: ● Fixtures & Furniture: ● Vehicles: ● Leasehold Building Improvements: 20-30 years 5-12 years 3-5 years 10-15 years 2-4 years 10 years F-15 Table of Contents Land is not depreciated. An item of property, plant and equipment and any significant part initially recognized is derecognized upon disposal or when no future economic benefits are expected from its use or disposal. Any gain or loss arising on derecognition of the asset (calculated as the difference between the net disposal proceeds and the carrying amount of the asset) is included in the income statement when the asset is derecognized. The assets’ residual values, useful lives and methods of depreciation are reviewed at each financial year-end and adjusted prospectively, if appropriate. Right-of-use assets and related liabilities Right-of-use assets: The Company recognizes right-of-use assets at the commencement date of the lease (i.e., the date the underlying asset is available for use). Right-of-use assets are measured at cost, less any accumulated depreciation and impairment losses, and adjusted for any remeasurement of lease liabilities. The cost of right-of-use assets includes the amount of lease liabilities recognized, initial direct costs incurred, the estimated cost of any asset retirement obligation and lease payments made at or before the commencement date less any lease incentives received. Unless the Company is reasonably certain to obtain ownership of the leased asset at the end of the lease term, the recognized right-of-use assets are depreciated on a straight-line basis over the shorter of its estimated useful life and the lease term: ● Property leased Assets: ● Leased machines: ● Leased vehicles: Lease terms up to 10 years or useful life of 10-15 years when reasonably certain that ownership will be obtained at the end of the lease Lease terms up to 10 years or useful life of 5-10 years when reasonably certain that ownership will be obtained at the end of the lease Lease terms up to 4 years or useful life of 4 years when reasonably certain that ownership will be obtained at the end of the lease Right-of-use assets are subject to impairment. Lease liabilities: At the commencement date of the lease, the Company recognizes lease liabilities measured at the present value of lease payments to be made over the lease term. The lease payments include fixed payments (including in substance fixed payments) less any lease incentives receivable, variable lease payments that depend on an index or a rate, and amounts expected to be paid under residual value guarantees. The lease payments also include the exercise price of a purchase option reasonably certain to be exercised by the Company and payments of penalties for terminating a lease, if the lease term reflects the Company exercising the option to terminate. The variable lease payments that do not depend on an index or a rate are recognized as expense in the period on which the event or condition that triggers the payment occurs. In calculating the present value of lease payments, the Company uses the incremental borrowing rate at the lease commencement date if the interest rate implicit in the lease is not readily determinable. After the commencement date, the amount of lease liabilities is measured at amortized cost using the effective interest rate method. In addition, the carrying amount of lease liabilities is remeasured when there is a change in future lease payments arising from a change in an index or a rate, if there is a change in the Group’s estimate of the amount expected to be payable under a residual value guarantee, if the Group changes its assessment of whether it will exercise a purchase, extension or termination option or if there is a revised in- substance fixed lease payment. When the lease liability is remeasured in this way, a corresponding adjustment is made to the carrying amount of the right-of-use asset, or is recorded in profit or loss if the carrying amount of the right-of-use asset has been reduced to zero. F-16 Table of Contents Short-term leases and leases of low-value assets: The Company applies the short-term lease recognition exemption to its short-term leases of machinery and equipment (i.e., those leases that have a lease term of 12 months or less from the commencement date and do not contain a purchase option) however this exemption is not applied for property leases. It also applies the lease of low-value assets recognition exemption to leases of office equipment that are considered of low value (i.e., below € 5k). Lease payments on short-term leases and low-value assets are recognized in the income statement when incurred. Borrowing costs Borrowing costs directly attributable to the acquisition, construction or production of a qualified asset that necessarily takes a substantial period of time to prepare for its intended use or sale are capitalized as part of the cost of the respective assets. All other borrowing costs are expensed in the period they occur. Borrowing costs consist of interest and other costs that an entity incurs in connection with the borrowing of funds. Research and development Research and development includes the costs incurred by activities related to the development of software solutions (new products, updates and enhancements), guides and other products. Development activities involve the application of research findings or other knowledge to a plan or a design of new or substantially improved (software) products before the start of the commercial use. Development expenditures on an individual project are recognized as an intangible asset when the Group can demonstrate: ● the technical feasibility of completing the intangible asset so that the asset will be available for use or sale; ● its intention to complete and its 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. The Group has 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) the Group has 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, it is highly likely that the Group will be able 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 the Group for a significant portion, but not all, 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. Internally generated intangible assets from proprietary software are amortized over their useful lives, starting from the moment they are ready for use/available for sale. Following initial recognition of the development expenditure as an asset, the asset is carried at cost less any accumulated amortization and accumulated impairment losses. Amortization of the asset begins when development is complete and the asset is available for use. It is amortized over the period of expected future benefit, which is determined on a project-by-project basis. Amortization is recorded in research and development expenditure. During the period of development, the asset is tested for impairment at least annually or whenever there is an indication of impairment. Intangible assets other than goodwill and capitalized development expenditures Intangible assets comprise acquired technology and customer portfolio, patents and licenses and technology and customers acquired in connection with business combinations. Those intangible assets are measured on initial recognition at cost, except for the acquired technology and customers arising from business combinations, which are measured initially at fair value. Following initial recognition, intangible assets other than goodwill are carried at cost less any accumulated amortization and accumulated impairment losses, if any. F-17 Table of Contents The useful life of the intangible assets is as follows: ● Software: ● Perpetual licences for ERP & front end software: ● Software with subscription license: ● Patents and licenses: ● Acquired customers and Technology: ● Order Backlog: 3 years; 10 years; subscription term 10 years; 5-20 years; Period over which orders will be completed. The intangible assets with finite lives are amortized over their useful economic life and assessed for impairment whenever there is an indication that the intangible asset may be impaired. The amortization period and the amortization method for an intangible asset with a finite useful life are reviewed at least at the end of each reporting period. The amortization expense on intangible assets with finite lives acquired through business combination is recognized in the consolidated income statement in the line “net other operating income”. Impairment of goodwill and other non-financial assets (excluding inventories and deferred tax assets) Impairment tests on goodwill and other intangible assets with indefinite useful economic lives, assets under construction or capitalized development expenses which are not amortized yet, are undertaken annually at the financial year end. Other non-financial assets and goodwill are subject to impairment tests whenever events or changes in circumstances indicate that their carrying amount may not be recoverable. Where the carrying value of an asset exceeds its recoverable amount (i.e. the higher of value in use and fair value less costs to sell), the asset is written down accordingly. Where it is not possible to estimate the recoverable amount of an individual asset, the impairment test is carried out on the smallest Group of assets to which it belongs for which there are separately identifiable cash flows: its cash generating units (CGUs). Goodwill is allocated on initial recognition to each of the Group’s CGUs that are expected to benefit from the synergies of the combination giving rise to the goodwill. The Group bases its impairment calculation on detailed budgets and forecast calculations, which are prepared separately for each of the Group’s CGUs to which the individual assets are allocated. These budgets and forecast calculations generally cover a period of five years. For longer periods, a long-term growth rate is calculated and applied to future cash flows projected after the fifth year. Impairment charges are included in profit or loss, except, where applicable, to the extent they reverse gains previously recognized in other comprehensive income. An impairment loss recognized for goodwill is not reversed. Where goodwill forms part of a cash-generating unit and part of the operation within that unit is disposed of, the goodwill associated with the operation disposed of is included in the carrying amount of the operation when determining the gain or loss on disposal of the operation. Goodwill disposed of in this circumstance is measured based on the relative values of the operation disposed of and the portion of the cash-generating unit retained. Inventories and Contracts in progress Inventories are valued at the lower of cost and net realizable value. Costs incurred in bringing each product to its present location and condition are accounted for as follows: ● Raw materials: purchase cost on a first in, first out basis; and ● Finished goods and work in progress: cost of direct materials and labor and a proportion of manufacturing overheads based on the normal operating capacity, but excluding borrowing costs. Net realizable value is the estimated selling price in the ordinary course of business, less estimated costs of completion and the estimated costs necessary to make the sale. A write-off of inventories is estimated based on an ageing or rotation analysis. F-18 Table of Contents Work in progress relates to production of inventory for which a customer has not yet been secured, while contracts in progress are contract assets that relate to production for specific customers in performance of a signed contract. We refer also to the accounting policy on revenue recognition. Financial assets Trade receivables and debt instruments issued are initially recognized when they are originated. All other financial assets are initially recognized when the Group become a party to the contractual provisions of the instrument. Financial assets are classified at initial recognition, and subsequently measured either at amortized cost, either fair value through other comprehensive income (OCI), and fair value through profit or loss. The classification of financial assets at initial recognition depends on the financial asset’s contractual cash flow characteristics and the Group’s business model for managing them. Except for trade receivables that do not contain a significant financing component or for which the Group has applied the practical expedient, the Group initially measures a financial asset at its fair value plus transaction costs, in the case of a financial asset not at fair value through profit or loss. Trade receivables that do not contain a significant financing component or for which the Group has applied the practical expedient are measured at the transaction price. For purposes of subsequent measurement, financial assets are classified in four categories: ● Financial assets at amortized cost; ● Financial assets at fair value through OCI with recycling of cumulative gains and losses (debt instruments); ● Financial assets designated at fair value through OCI with no recycling of cumulative gains and losses upon derecognition (equity instruments); and ● Financial assets at fair value through profit or loss. Financial assets measured at amortized cost This category is the most relevant to the Group. The Group measures financial assets at amortized cost if both of the following conditions are met: ● The financial asset is held within a business model with the objective to hold financial assets in order to collect contractual cash flows; and ● The contractual terms of the financial asset give rise on specified dates to cash flows that are solely payments of principal and interest on the principal amount outstanding. Financial assets, trade and other receivables, cash and cash equivalents at amortized cost are subsequently measured using the effective interest rate (EIR) method and are subject to impairment. Gains and losses are recognized in profit or loss when the asset is derecognized, modified or impaired. Financial assets at fair value through OCI with recycling of cumulative gains and losses (debt instruments) The Group currently does not have financial assets at fair value through OCI with recycling of cumulative gains and losses. Financial assets designated at fair value through OCI with no recycling of cumulative gains and losses upon derecognition (equity instruments) The Group has irrevocably elected at initial recognition to classify the minority equity investment in the non-listed company AM-Flow BV, as disclosed in Note 10 and Note 20, as financial asset designated at fair value through OCI as this measurement is most representative of the business model for these assets. Gain and losses on these financial assets are never recycled to profit and loss. Equity instruments designated at fair value through OCI are not subject to impairment assessment. F-19 Table of Contents Financial assets measured at fair value through profit or loss The Group has the following financial assets classified as financial assets at fair value through profit or loss: ● Derivatives as disclosed in Note 10; ● convertible loan granted to the company Fluidda as disclosed in Note 10. Those financial assets are carried in the statement of financial position at fair value with changes recognized in the income statement in the lines financial income/expense. Derecognition A financial asset is derecognized when: ● The rights to receive cash flows from the asset have expired, or ● The Group has transferred its rights to receive cash flows from the assets. The Group has a factoring agreement in place with one subsidiary whereby its rights to receive the cash flows from the trade receivables are transferred to the factor on a non-recourse basis. The related trade receivables are derecognized at the moment that the cash is received from the factor. Impairment of financial assets Further disclosures relating to impairment of financial assets are also provided in Note 3 Significant accounting judgments, estimates and assumptions. The Group recognizes an allowance for expected credit losses (ECLs) for all debt instruments not held at fair value through profit or loss. For trade receivables and contract assets, the Group applies a simplified approach in calculating ECLs. A loss allowance is recognized at each reporting date based on lifetime ECLs. The Group established a provision matrix that is based on its historical loss experience, adjusted for forward-looking factors specific to the debtors and the economic environment. For all other receivables, ECLs are based on the difference between the contractual cash flows due in accordance with the contract and all the cash flows that the Group expects to receive, discounted at an approximation of the original effective interest rate. The expected cash flows will include cash flows from the sale of collateral held or other credit enhancements that are integral to the contractual terms. ECLs are recognized in two stages. For credit exposures for which there has not been a significant increase in credit risk since initial recognition, ECLs are provided for credit losses that result from default events that are possible within the next 12-months (a 12-month ECL). For those credit exposures for which there has been a significant increase in credit risk since initial recognition, a loss allowance is required for credit losses expected over the remaining life of the exposure, irrespective of the timing of the default (a lifetime ECL). When determining whether the credit risk has increased significantly since initial recognition, the group considers reasonable and supportable information that is relevant and available with undue cost or effort, including both quantitative and qualitative information and analysis, based on the Group’s historical experience and informed credit assessments, that includes forward-looking information. The Group assumes that the credit risk on a financial asset has increased significantly if it is more than 30 days past due. An event of default takes place when the debtor is unlikely to pay its credit obligations to the Group in full or when the financial asset is more than one year past due. Financial liabilities All financial liabilities are recognized initially at fair value and, in the case of loans and borrowings and payables, net of directly attributable transaction costs. The Group’s financial liabilities include trade and other payables, loans and borrowings including bank overdrafts and derivative financial instruments including written put options over non-controlling interests. F-20 Table of Contents Financial liabilities at amortized cost The trade and other payables, and loans and borrowings are classified as financial liabilities at amortized cost. Those financial liabilities are measured at amortized cost using the effective interest rate method. Gains and losses are recognized in the income statement when the liabilities are derecognized as well as through the effective interest rate method amortization process. Financial liabilities at fair value through profit and loss The derivative financial instruments are classified as financial liabilities at fair value through profit and loss. Compound financial instruments The Group has issued convertible debt which is accounted for as a compound financial instrument. For those instruments, the Group determines the carrying amount of the liability component by measuring the fair value of a similar liability (including any embedded non-equity derivative features) that does not have an associated equity component. The carrying amount of the equity instrument is then determined by deducting the fair value of the financial liability from the fair value of the compound financial instrument as a whole. Directly attributable transaction costs are apportioned between the liability and equity components of the convertible debt instrument, based on the allocation of proceeds to the liability and equity components when the instruments are initially recognized. Subsequent to initial recognition, the liability component of a compound financial instrument, is measured at amortized cost using the effective interest method. The equity component of a compound financial instrument is not remeasured. Derecognition A financial liability is derecognized when the obligation under the liability is discharged or cancelled or expires. Offsetting Financial assets and financial liabilities are offset and the net amount is reported in the consolidated statement of financial position if there is a currently enforceable legal right to offset the recognized amounts and there is an intention to settle on a net basis, or to realize the assets and settle the liabilities simultaneously. Share capital Financial instruments issued by the Group are classified as equity only to the extent that they do not meet the definition of a financial liability or financial asset. The Group’s ordinary shares are classified as equity instruments. Provisions Provisions are recognized when the Group has a present obligation (legal or constructive) as a result of a past event, it is probable that an outflow of resources embodying economic benefits will be required to settle the obligation and a reliable estimate can be made of the amount of the obligation. Pension benefits The Group has a defined contribution obligation where the Group pays contributions based on salaries to an insurance company, in accordance with the laws and agreements in each country. The Belgian defined contribution pension plans are by law with variable minimum returns based on the Belgian government bonds, with a minimum of 1.75% and a maximum of 3.75%, effective for contributions paid as from 2016. For contribution paid until 2015, the minimum guaranteed return is 3.25% on employer contributions and 3.75% on employee contributions. These plans qualify as defined benefit plans. Contributions are recognized as expenses for the period in which employees perform the corresponding services. Outstanding payments at the end of the period are shown as other current liabilities. F-21 Table of Contents Share based payments Directors and employees (including senior executives) of the Group receive remuneration in the form of share-based payments, whereby employees render services as consideration for equity instruments (equity-settled transactions). The Group currently has only warrants and share-appreciation rights as share-based payments. Equity-settled transactions Equity-settled share-based payments to employees and others providing similar services are measured, indirectly, at the fair value of the equity instruments granted. The cost of equity-settled transactions is recognized, together with a corresponding increase in other capital reserves in equity, over the period in which the performance and/or service conditions are fulfilled. The cumulative expense recognized for equity-settled transactions at each reporting date until the vesting date reflects the extent to which the vesting period has expired and the Group’s best estimate of the number of equity instruments that will ultimately vest. The income statement expense or credit for a period represents the movement in cumulative expense recognized at the beginning and end of that period and is recognized as employee benefits expense. The Group does currently only have equity-settled share-based payments that have service-based vesting conditions and no instruments with market vesting conditions. No expense is recognized for awards that do not ultimately vest. When the terms of an equity-settled award are modified, the minimum expense recognized is the expense as if the terms had not been modified, if the original terms of the award are met. An additional expense is recognized for any modification that increases the total fair value of the share-based payment transaction or is otherwise beneficial to the employee as measured at the date of modification. When an equity-settled award is cancelled, it is treated as if it vested on the date of cancellation, and any expense not yet recognized for the award is recognized immediately. This includes any award where non-vesting conditions within the control of either the entity or the employee are not met. However, if a new award is substituted for the cancelled award and designated as a replacement award on the date that it is granted, the cancelled and new awards are treated as if they were a modification of the original award, as described in the previous paragraph. Cash-settled transactions The Group has cash-settled share-based payment transactions for certain employees in certain countries due to legal requirements (in the form of share-appreciation rights). The cost of cash-settled transactions is measured initially at fair value at the grant date. This fair value is expensed over the period until the vesting date with recognition of a corresponding liability. The liability is remeasured to fair value at each reporting date up to, and including the settlement date, with changes in fair value recognized in employee benefits expense. Other long-term employee benefits The Group’s net obligation for long-term employee benefits is equal to the value of future benefits acquired by personnel in exchange for services rendered in the current and prior periods. This expense is mainly shown under the research and development expenses in the consolidated income statement. Revenue from contracts with customers The Group’s revenue, which is presented net of sales taxes, is primarily generated by the sale of our software and 3D printed products and services. Software revenue is comprised of perpetual and periodic licenses, maintenance revenue and software development service fees. Perpetual license holders may opt to take an annual maintenance contract, which leads to annual fees. Periodic licenses entitle the customer to maintenance, support and product updates without additional charge. Revenue from prototypes and end products involving 3D printing technology is derived from our network of production centers and may include support and services such as pre-production collaboration prior to the actual production. The Group sells its products and software through its direct sales force and through authorized distributors. F-22 Table of Contents Software license revenue, maintenance and/or software development service fees may be bundled in one arrangement or may be sold separately. The Group recognizes revenue for goods including software based on the five-step model per the requirements of IFRS 15. ● Identify the contract(s) with a customer; ● Identify the performance obligations in the contract; ● Determine the transaction price; ● Allocate the transaction price to the performance obligations in the contract; and ● Recognize revenue when (or as) the entity satisfies a performance obligation. Revenue from contracts with customers is recognized when control of the goods or services are transferred to the customer at an amount that reflects the consideration to which the Group is expected to be entitled in exchange from those goods and services. If the consideration in a contract includes a variable amount, the Group estimates the amount of consideration to which it will be entitled in exchange for transferring the goods to the customer. The variable consideration is estimated at contract inception and constrained until it is highly probable that a significant revenue reversal in the amount of cumulative revenue recognized will not occur when the associated uncertainty with the variable consideration is subsequently resolved. Variable consideration is mainly related to quantities sold, volume (step-based) rebates and development time spent. Prototypes and end products involving 3D printing technology The Group recognizes revenue on the sale of goods to the customer or distributor at a point in time when control of the asset is transferred, generally upon shipment or delivery considering the shipment terms (usually Ex-works or FOB Time of Shipment Incoterms (International Commercial Terms)). Perpetual licensed software The sale and/or license of software products is deemed to have occurred at a point in time, i.e. when a customer either has taken possession of or has the ability to take immediate possession of the software and the software key. Most of the perpetual software licenses include one year maintenance and support services as a separate performance obligation. The Company sells these maintenance services also on a stand-alone basis and is therefore capable of determining their stand-alone selling price. On this basis, the amount of the embedded maintenance is separated from the fee for the perpetual license and is recognized ratably over the period to which they relate. Time-based licensed software The time-based license agreements include the use of a software license for a fixed term and maintenance and support services during the same period. The Company does not sell time-based licenses without maintenance and support services and therefore revenues are satisfied over time for the entire arrangements and are recognized ratably over the term. Maintenance and support services Maintenance and support services are satisfied over time and as such, the Group recognizes this revenue ratably on a straight-line basis over the term that the maintenance service is provided. In general, maintenance services are not automatically renewed. A maintenance and support contract may include a reinstatement for previous years when the customer did not have a maintenance and support contract previously. Revenue from reinstatements is recognized immediately when the maintenance and support services commence. F-23 Table of Contents Software development services (SDS) SDS include customized development of software components for customers. Revenue from SDS agreements when distinct from other performance obligations is satisfied over time or at a point in time, depending whether one of the IFRS 15.35 criteria for performance obligations to be satisfied over time is met or not. In case of recognition over time, revenue is recognized either on time and material basis or on the stage of completion of each service when the percentage of completion can be measured reliably. The Company determines the percentage-of-completion by comparing labor hours incurred to-date to the estimated total labor hours required to complete the project. The Company considers labor hours to be the most reliable available measure of progress on these projects. Adjustments to the Company’s estimates of the time to completion are made when facts resulting in a change become known. When the estimate indicates that a loss will be incurred, such loss is recognized immediately. In case of recognition at a point in time revenue is recognized when control over the product is transferred to the customer. Contracts with multiple performance obligations The Group has entered into a number of contracts with multiple performance obligations, such as when selling perpetual licenses that may include maintenance and support (included in the price of perpetual licenses) and time-based licenses (that include embedded maintenance and support, both of which may be sold with software development services, training, and other product sales). In some cases, the Group delivers software development services bundled with the sale of the software. The Group evaluates whether each performance obligation is distinct from each other, i.e. the customer can benefit from the good or service on its own, or with readily available resources. Certain development services significantly modify and/or enhance the software license and as such are not considered distinct and combined with the software license. In those contracts, whether sold to end-customers or to collaboration partners, the Group uses either price list, historical pricing information or management’s best estimate of selling prices (e.g. also using a cost-plus method) to determine the stand-alone selling price for each distinct performance obligation, including software and software-related services such as maintenance and support. In general, elements in such arrangements are also sold on a stand-alone basis and stand-alone selling prices are readily available. If the stand-alone selling price of one or more goods or services in such arrangements is highly variable or uncertain, the Group estimates 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. Revenue is allocated to each distinct performance obligation (“PO”) based on the relative percentage of the stand-alone selling price for each PO compared to the total of stand-alone selling prices for all PO over the total transaction price and is recognized when the revenue recognition criteria described above are met. Contracts with collaboration partners in the medical segment also include multiple elements such as software, maintenance and support services, training, software development services, 3D printed products and royalties. Revenue from those contracts is determined and recognized consistent with other multiple element arrangements. For certain contracts with collaboration partners, the Company receives up-front fees, paid by customers for certain exclusivity rights, which may be bundled with transfer of title, rights and ownership of certain software products and maintenance and support services. In case the up-front fees do not relate to already delivered good or services, the Group includes the up-front fees in the total transaction price which is then allocated to all the distinct performance obligations. Other contracts with collaboration partners include prepaid fees to purchase a maximum number of “Plan Only” cases or case ‘bundles’ during a 12-month period. In this case, the prepaid fees are recognized over the period of 12 months based on the expected number of cases that will be purchased. Contract assets A contract asset is the right to consideration in exchange for goods or services transferred to the customer. If the Group performs by transferring goods or services to a customer before the customer pays consideration or before payment is due, a contract asset is recognized for the earned consideration that is conditional. Contract assets are only contracts in progress that are disclosed with the line inventory and contracts in progress in the statement of financial position. We refer to our accounting policies regarding Inventories and Contracts in Progress. F-24 Table of Contents Contract liabilities A contract liability is the obligation to transfer goods or services to a customer for which the Group has received consideration (or an amount of consideration is due) from the customer. If a customer pays consideration before the Group transfers goods or services to the customer, a contract liability is recognized when the payment is made or the payment is due (whichever is earlier). Contract liabilities are recognized as revenue when the Group performs under the contract. Contract liabilities are presented as deferred income in the statement of financial position. Contract costs The Group does not have significant costs to obtain contracts and those costs are expensed as incurred. The Group may have costs incurred in fulfilling contracts that are accounted for as intangible assets. When those costs are not in scope of another standards, these costs are accounted for under contracts in progress (see contract assets). For certain contracts, the Group may have significant software development expenses that are not considered a “distinct performance obligation” which are accounted for as an intangible asset. The Group evaluates whether those costs meet the recognition criteria for an intangible asset and when criteria are not met, expenses those costs as incurred. Government grants 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 in Freiberg (Germany). Where retention of a government grant related to assets or to income, is 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. Other financial income and expenses Other financial income and expenses include mainly foreign currency gains or losses on financial transactions and bank related expenses. Taxes Current income tax Income tax assets and liabilities for the current period are measured at the amount expected to be recovered from or paid to the taxation authorities. The tax rates and tax laws used to compute the amount are those that are enacted or substantively enacted, at the reporting date. Current income tax relating to items that are recognized directly in equity is recognized in equity and not in the income statement. Management periodically evaluates positions taken in the tax returns with respect to situations in which applicable tax regulations are subject to interpretation and establishes provisions where appropriate. Deferred tax Deferred tax is calculated using the liability method on temporary differences at the reporting date between the tax bases of assets and liabilities and their carrying amounts for financial reporting purposes. F-25 Table of Contents Deferred tax liabilities are recognized for all taxable temporary differences. Deferred tax assets are recognized for all deductible temporary differences, carry forward of unused tax credits and unused tax losses, to the extent that it is probable that taxable profit will be available against which the deductible temporary differences or the carry forward of unused tax credits and unused tax losses can be utilized. In order for any deferred tax assets to be recognized, and at a minimum, the respective Materialise entity should have recorded a taxable profit in the current year and it should be probable that a taxable profit will be achieved in the subsequent year. The carrying amount of deferred tax assets is reviewed at each reporting date and reduced to the extent that it is no longer probable that sufficient taxable profit will be available to allow all or part of the deferred tax asset to be utilized. Unrecognized deferred tax assets are reassessed at each reporting date and are recognized to the extent that it has become probable that future taxable profits will allow the deferred tax asset to be recovered. Deferred tax assets and liabilities are measured at the tax rates that are expected to apply in the year when the asset is realized or the liability is settled, based on tax rates (and tax laws) that have been enacted or substantively enacted at the reporting date. Deferred tax assets and deferred tax liabilities are offset, if a legally enforceable right exists to set off current tax assets against current income tax liabilities and the deferred taxes relate to the same taxable entity and the same taxation authority. Sales tax Revenue, expenses and assets are recognized net of the amount of VAT, except: ● Where the sales tax incurred on a purchase of assets or services is not recoverable from the taxation authority, in which case the sales tax is recognized as part of the cost of acquisition of the asset or as part of the expense item as applicable; and ● Receivables and payables that are stated with the amount of sales tax included. The net amount of sales tax recoverable from, or payable to, the taxation authority is included as part of receivables or payables in the statement of financial position. Significant accounting judgments, estimates and assumptions The preparation of the Group’s consolidated financial statements requires management to make judgments, estimates and assumptions that affect the reported amounts of revenue, expenses, assets and liabilities, and related disclosures. Uncertainty about these assumptions and estimates could lead to outcomes that require a material adjustment to the carrying amount of assets or liabilities for future periods. The Group reviews its estimates, assumptions and judgments on an ongoing basis, 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, provisions for expected credit losses, convertible loans, equity instruments, useful lives of certain assets and leases. The Group has based its assumptions and estimates on the parameters that were available when the consolidated financial statements were prepared. However, existing conditions and assumptions about future developments, may change due to market changes or circumstances beyond the Group’s control. Such changes are incorporated into the assumptions as they occur. Revenue recognition Our revenue recognition policy requires management to make significant estimates. Management analyzes various factors, including an evaluation of specific transactions, historical experience, creditworthiness of customers and current market and economic conditions. Changes in judgments based upon these factors may affect the timing and amount of revenues and expenses recognized and, consequently, the results of operations and financial condition. Significant estimates and judgments relate to: ● Assessing whether a performance obligation is distinct in a bundled sales transactions; ● Estimation of the variable considerations and the revenue constraint; ● Estimation of 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. F-26 Table of Contents The Group makes 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 in 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. The relevant assessments include but are not limited to 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 licenses are combined with the manufacturing of the 3D printed guides, as the software license has no benefit to the customer without the manufacturing services. ● Whether the development services are distinct from other performance obligations - in most cases these performance obligations are distinct but for certain contracts, the software license may be combined with the license and the 3D printed guides as one distinct performance obligation. For stand-alone selling prices, the Group uses prices from price lists or historical prices for similar transactions. However, in certain cases such information is not readily available and in those cases the Group estimates the stand-alone selling price based on a cost plus mark-up or other estimate. 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. If the Group determines that the stand-alone selling price of one or more goods or services in a multiple element arrangement is highly variable or uncertain, the Group estimates 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. 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, 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 and 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 (each less than 50%), the Group 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 constrained when the Group determines, based on historical experience, a high reliable business forecast and/or the time frame of the estimates, 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 are made in the period 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 of completion for each contract. Different assumptions can produce materially different results. Development expenses Under IAS 38, internally generated intangible assets from the development phase are recognized if certain conditions are met. These conditions include technical feasibility, the intention to complete, the ability to use or sell the asset under development, the availability of adequate technical, financial and other resources to complete the development, the ability to reliably measure the expenditure attributable to the intangible asset during development and evidence of how the asset will generate probable future economic benefits. The cost of a recognized internally generated intangible asset includes all directly attributable costs necessary to make the asset suitable for use as intended by management. In contrast, all expenditures arising from the research phase are expensed as incurred. F-27 Table of Contents Determining whether internally generated intangible assets from development should 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 completion of the asset is technically feasible considering a company-specific approach, the likelihood of future economic benefits from sale or use, including an assessment of whether FDA approval will be obtained. The Group has determined that the conditions for recognizing internally generated intangible assets from its own software, guides and other product development activities are not met until shortly before the products are available for sale, unless either (i) the Group has 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 at the specific request of the customer, the Group intends to market the product to other parties than the customer, the development is subject to an agreement and the substance of the agreement is that the customer will reimburse the Group for a significant portion of the development costs incurred. As such, development expenditures that do not meet the above criteria and expenditures for the research phase of internal projects are recognized in the consolidated income statement as incurred. This assessment is monitored by the Group on a regular basis. The Group capitalized a total of K€3,422 of development expenses during 2022 of which: ● K€2,438 related to capitalized internal development expenses of our digital transformation program; and ● K€984 related to the transformation of the platform architecture to enable our software products to make the transition from desktop to (hybrid) cloud. Of the K€1,959 accumulated total asset under construction balance, K€1,287 was transferred to software, while K€672 was impaired per December 31, 2022. 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. For any deferred tax assets to be recognized, and at a minimum, the respective Materialise entity should have recorded a taxable profit in the current year and it should be probable that a taxable profit will be achieved in the subsequent year. As of December 31, 2022, the Group had current and non-current receivables related to tax credits for an amount of K€5,105 (2021: K€4,717; 2020: K€4,647) As of December 31, 2022, the Group had K€87,558 (2021: K€58,161; 2020: K€50,538) of unused tax losses carried forward and unused Innovation Income Deductions, of which K€45,245 related to Materialise NV (2021: K€35,578; 2020: K€27,878). These losses relate to the parent 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 the Group. With respect to the unused tax losses and Innovation Income Deduction of Materialise NV, the deferred tax asset recognized at December 31, 2022 was limited to €0.2 million (2021: €0.0 million, 2020: €0.0 million). Under the Belgian Innovation Income Deduction system, companies can deduct up to 85% of their net innovation income from the taxable basis. According to the Group’s policy the Company has assessed that no additional deferred tax asset should be recognized with respect to its unused tax losses and unused Innovation Income Deductions carried forward in Belgium. With respect to the unused tax losses of the other entities, we recognized at December 31, 2022 a deferred tax asset of € 1.6 million for Materialise USA related to losses carried forward from the acquired entities Link3D and Identify3D. No deferred tax assets were recognized in 2021 and 2020 except for our tax unity in Germany where we recorded a deferred tax asset of € 0.3 million related to 2020 losses and Materialise Motion where we recorded a deferred tax asset of € 1.8 million against a deferred tax liability of € 2.0 million. The Group has not recognized deferred tax assets on unused tax losses and Innovation Income Deduction totaling K€19,101 in 2022 (2021: K€12,033; 2020: K€22,661) 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. F-28 Table of Contents If all deferred tax assets related to tax losses carried forward and unused Innovation Income Deduction would meet the criteria for recognition, the net result would have improved by K€19,101 in 2022 through a deferred tax benefit. This would represent the planned recovery of K€75,361 of carried forward tax losses and Innovation Income Deduction in future periods. Further details on taxes are disclosed in Note 22.10. Impairment of goodwill, intangible assets and property, plant & equipment and determination of the cash-generating-unit. The Group has goodwill for a total amount of K€44,155 as of December 31, 2022 (2021: K€18,726; 2020: K€18,599) which has been subject to an impairment test. The 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 DCF model as well as the expected future cash-inflows and the growth rate used for extrapolation purposes. Also, as part of the impairment analysis, the Group needs to determine the different CGUs at the lowest non-aggregated level which requires the Group to make judgments about application of the criteria to determine the CGUs based on the facts and circumstances how the entities and business units within the CGU and within the Group operate and are monitored. The level of CGU may also have an impact on certain assumptions to make with regard to transfer pricing. The key assumptions used to determine the value in use for the different CGUs are disclosed and further explained in Note 5. The Group capitalized development expenses in 2022 for a total amount K€3,422 (2021: K€2,659; 2020: K€4,541). Those development expenses have been subject to an impairment test based on a discounted cash flow model with cash flows derived from the latest business plan. The value in use is sensitive to the discount rate used for the DCF model as well as the expected commercialization date for the products and the expected future cash inflows after commercialization. We refer to the section on development expenses above for further explanations. 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. During 2022 impairment charges have been recorded for K€672 (2021: K€177; 2020: K€4,606) related to the transformation of the platform architecture to enable our software products to make the transition from desktop to (hybrid) cloud. 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. Business combinations are discussed further in Note 4. The purchase price allocation process requires us to make 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. 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; and ● discount rates. F-29 Table of Contents Provision for expected credit losses of trade receivables and contract assets The Group uses 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 the Group’s historical observed default rates. The Group will calibrate the matrix to adjust the historical credit loss experience with forward-looking information. For instance, if forecast 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 every 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, forecast economic conditions and ECLs is a significant estimate. The amount of ECLs is sensitive to changes in circumstances and of forecast economic conditions. The Group’s historical credit loss experience and forecast of economic conditions may also not be representative of customer’s actual default in the future. Convertible debt instruments At December 31, 2022 the Group holds a convertible debt instrument issued by Fluidda which is measured at fair value through profit & loss. In determining the fair value of those convertible debt instruments, the Group considers different contractual parameters such as the repayment and conversion scenarios and dates. In addition, the Group needs to make significant estimates such as (i) the discount rate, (ii) the probabilities for each repayment and conversion scenario, (iii) the amount of a qualified capital increase that will determine the conversion factor and (iv) the timing for each repayment and conversion scenario. The convertible loan granted to Fluidda in January 2019 has a notional amount of K€2,500. The carrying value of the convertible loan as of December 31, 2022 amounted to K€3,494. The Group recorded a downward remeasurement of K€316 in financial expenses in 2022. Fluidda is a private start-up company which offers turnkey contract research services for drug development and medical device development. Fluidda is currently loss-making. The convertible loan has a duration of 7 years with a 10% annual interest rate which is capitalized. In the fair value analysis, the Group has applied a discount factor of 12.67% that is based on the estimated WACC of Fluidda reflecting the uncertainty in relation to the success of the company and the applied estimates by the Group. The Group previously granted a convertible loan to AM Flow in January 2020 with a notional amount of K€300. The loan was converted into shares of AM Flow in September 2020 at a fair value of K€307. AM Flow is currently loss-making. Equity investment held in Essentium The Group acquired an equity investment of K$3,300 in Essentium, a non-listed US company during 2018 and 2019. The Group has elected to measure the equity investment at fair value with changes in fair value recognized in OCI. At the end of 2021 Essentium was facing significant liquidity issues and significant uncertainty related to the fund-raising process and started a process of restructuring its organization. As a result of these elements, and considering the Group’s subordinate position as shareholder, the Group remeasured the fair value of its investment to zero on December 31, 2021 and recognized a K€3,443 downward fair value adjustment in OCI for the year ended December 31, 2021. Essentium raised funds in 2022 and restructured. However, the company continued making losses and its liquidity position remained critical. The Group determined that the fair value of this equity investment remained zero at December 31, 2022. Changes in useful life for certain assets We review the useful life of our definite lived intangible assets and property, plant and equipment on an annual basis considering the current facts and circumstances available. The intangibles with indefinite useful lives are reviewed each annual reporting to determine whether events and circumstances continue to support an indefinite useful life. F-30 Table of Contents Leases – estimating the discount rate and probability of exercising extension options/termination options and purchase options The Group cannot always determine the interest rate implicit in the lease contract and therefore, the Group has to estimate the incremental borrowing rate to measure certain lease liabilities such as buildings. The Group uses for buildings the property yield as reference to determine the incremental borrowing rate. For other assets, the Group generally uses the interest rate implicit in the lease contract or applies the incremental borrowing rate for a portfolio of similar assets. The incremental borrowing rate reflects what the Group “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 case of property leases and/or purchase options in case of leases. The Group estimates whether it is reasonably certain or not, whether those options will be exercised or not, which impact the lease term in case of extension options and termination options and the period over which the lease assets are depreciated in case of purchase options. 4 Business Combinations Acquisitions in 2022 Materialise Link3D On April 9, 2021, the Group acquired an option to buy Link3D Inc. On November 15, 2021, Materialise provided notice to Link3D of its intention to exercise the option. The acquisition was completed on January 4, 2022. This acquisition was realized by the Group’s U.S. subsidiary, Materialise USA, LLC by exercising our call option. As a result of this transaction, Materialise USA became the sole shareholder of Link3D. On January 4, 2022, the Group completed the acquisition and obtained control of Link3D Inc. Link3D is an additive workflow and digital manufacturing software company. The Group acquired 100% of voting equity interests in Link3D Inc. for a total cash consideration of K€ 26,747. The acquisition of Link3D is expected to strengthen and accelerate the creation of the Materialise software platform, particularly for companies that are scaling up their additive manufacturing operations to volume production. By integrating Link3D’s additive MES (Manufacturing Execution System) solution with the Materialise Magics software suite into a unified, cloud-based software platform, manufacturers will be able to run and continuously improve the most efficient, repeatable, automated and controlled processes to mass- produce identical or customized products. This process extends beyond the actual 3D printing operations and creates a closer alignment between 3D printing and conventional manufacturing, signaling the removal of the wall between both production environments. On October 1, 2022, Link3D was merged into parent entity Materialise USA.

The Group acquired 100% of voting equity interests in Link3D Inc. for a total consideration of K€26,747. This is the fair value of the identified assets and liabilities increased by a goodwill of K€23,251. The goodwill recognized is primarily attributable to the trained and knowledgeable workforce and to the expected synergies that will be realized at the level of development, manufacturing and the existing customer base. The goodwill is not deductible for income tax purposes. The accounting for the business combination resulted in fair values at date of acquisition of K€1,066 for Brands and trademarks (useful life of 1 year) and K€6,892 for software (useful life of 7 years). The valuation technique used to measure the fair value of brands and trademarks, as well as software, was the relief-from-royalty method. The relief-from-royalty method considers the discounted estimated royalty payments that the Group would be prepared to pay to license the respective asset under a contract if it did not own the asset. Key assumptions used in the application of this valuation technique include the forecasted year-on-year growth rate of revenue, the software royalty rate, the brands and trademarks royalty rate and the discount rate. A deferred tax liability was recognized of K€(2,270) on the adjusted fair values. The discount rate used for the valuation was set at 14.00%. The carrying value of the acquired receivables, the trade and other receivables approximate their fair value due to the short term character of these instruments. Trade receivables acquired comprised gross contractual amounts due of K€992, of which K€224 was expected to be uncollectible at the date of acquisition. The Link3D revenue included in the consolidated financial statement between acquisition date of January 4, 2022 and merger date October 1, 2022 amounted to K€ 2,631. The amount of revenue between the merger date and December 31, 2022 was K€993.

(“Identify3D” or “ID3D”) for a total cash consideration of K€3,853. The acquisition was realized by the Group’s U.S. subsidiary, Materialise USA, LLC. With the acquisition of Identify3D the Group wants to address growing data security and integrity requirements and market interest, and to make CO-AM the most secure software platform for distributed manufacturing. This acquisition will allow manufacturers to secure the flow of digital parts and maintain a competitive advantage. On December 31, 2022, Identify3D was merged into parent entity Materialise USA.

F-33 Table of Contents Acquisitions in 2021 The Group did not effect any business combinations in the course of 2021. Acquisitions in 2020 Materialise Motion The Group executed a share purchase agreement dated November 9, 2020 and acquired the remaining 50% of the shares of Materialise Motion NV (“Materialise Motion”, formerly RS Print) for a total purchase consideration in cash of K€5,220. The debt of previous owner of K€655 related to the called unpaid capital was transferred to the Group. Before this transaction, the Group already had a 50% interest in Materialise Motion. The fair value of the previously held equity method investment was valued at K€770. The corresponding gain was presented within net other operating income for the year ended December 31, 2020 (Note 22.6). In determining the fair value of the previously held equity method investment, a strategic discount, a minority discount and a discount for lack of marketability were considered in relation to the consideration paid for this transaction. Simultaneously with the share purchase agreement, Materialise Motion and RS Scan International NV (“RS Scan”), the former co- shareholder of Materialise Motion, entered into an asset purchase agreement regarding the acquisition by Materialise Motion of certain assets of RS Scan with closing date on 9 November 2020 for a total purchase consideration in cash of K€3,000.

As of October 2021, we completed the fair value analysis of the Materialise Motion business combination, which resulted in corresponding adjustments to the goodwill, consolidated reserves and deferred tax assets and deferred tax liabilities. The fair value of the identified assets and liabilities was K€1,743 higher than the provisional value at date of acquisition, with a corresponding reduction in goodwill of K€1,743. The accounting for the business combination resulted in fair values at date of acquisition of K€4,820 for developed technology based on the relief-from-royalty valuation method with royalty rates between 8.00% and 10.00% (useful life of 7 years), K€248 for customer relationships based on the multi-period excess earnings method (useful life of 15 years) and K€2,862 for contracts based on the multi- period excess earnings method (useful life of 7 years). A fair value adjustment was identified of K€265 for the inventory. At the same time, a deferred tax liability was recognized of K€(2,049) on these adjusted fair values. Upon the completion of the accounting for the business combination in 2021, the deferred tax assets were adjusted by K€1,743. The discount rate (post-tax WACC) used for the valuation was set at 15.80%. The carrying value of the acquired receivables, the trade and other receivables approximate their fair value due to the short term character of these instruments. There are no contingent considerations payable. The goodwill recognized is primarily attributable to the trained and knowledgeable workforce and to the expected synergies that will be realized at the level of development, manufacturing and the existing customer base. The goodwill is not deductible for income tax purposes. 5 Goodwill The goodwill has been allocated to the cash generating units (“CGU”) as follows: in 000€ CGU: MAT Software CGU: e-Prototypy CGU: ACTech CGU: OrthoView CGU: MAT NV Manufacturing (Metal) CGU: Engimplan CGU: Materialise Motion Total F-35 2022 28,933 730 8,812 4,505 — — 1,175 44,155 As of December 31, 2021 3,241 743 8,812 4,755 — — 1,175 18,726 2020 3,241 749 8,812 4,445 177 — 1,175 18,599 Table of Contents The changes in the carrying value of the goodwill can be presented as follows for the years 2022, 2021 and 2020: in 000€ At January 1, 2020 Additions Impairment Currency translation At December 31, 2020 Additions Impairment Currency translation At December 31, 2021 Additions Impairment Currency translation At December 31, 2022 Gross 19,711 1,175 — (816) 20,070 — — 304 20,374 25,691 — (263) 45,802 Impairment (104) — (1,367) — (1,471) — (177) — (1,648) — — — (1,648) Total 19,607 1,175 (1,367) (816) 18,599 — (177) 304 18,726 25,691 — (263) 44,155 The goodwill of Orthoview (UK) and e-Prototypy (PL) include respectively K€(250) and K€(13) impact of currency translation in 2022. The Group has performed an impairment test for all CGUs, estimating the Value-in-Use 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 MAT Software CGU is included in the reportable segment “Materialise Software”. The CGUs ACTech, e-Prototypy (PL), MAT NV Manufacturing (Metal) and Materialise Motion are included in the reportable segment “Materialise Manufacturing”. The CGUs Orthoview (UK) and Engimplan (BR) are included in the reportable segment “Materialise Medical”. CGU: MAT Software The goodwill allocated to the CGU MAT software relates to the goodwill from the acquisition of Cenat in 2015, the goodwill related to the acquisition of Marcam in 2011 (DE-3D Printing Software), the goodwill from the acquisition of Link3D in 2022 and the goodwill from the acquisition of Identify3D in 2022. The impairment test is based on the discounted cash flows resulting from the CGU MAT Software, considering a period of five years. The main assumptions for goodwill impairment testing include a discount rate (based on WACC) of 9.67% (11.04% pre-tax) and a perpetual growth rate of 5%. Other assumptions include the year-on-year growth rate of the revenue, gross margin and the operating costs which has been determined by management based on past experience. It was concluded that the value in use is higher than the carrying value of the cash generating unit of K€43,002. Based on the sensitivity analyses performed by the Group, including analyses whereby the discount rate would increase by 100 basis points or the perpetual growth rate would be zero, there are no reasonably possible changes in assumptions that would reduce the value in use below the carrying value of the cash generating unit. CGU e-Prototypy The goodwill relates to the acquisition of the Polish entity e-Prototypy . The impairment test on the CGU e-Prototypy is based on the discounted cash flows considering a period of five years. The main assumptions include a discount rate (based on WACC) of 12.72% (14.52% pre-tax) and a perpetual growth rate of 2%. Other assumptions include the year-on-year growth rate of the revenue, gross margin and the operating costs which has been determined by management based on past experience and continued investments in capex in new 3D printing equipment. It was concluded that the value in use is significantly higher than the carrying value of the cash generating unit of K€3,558. Based on the sensitivity analyses performed by the Group, including analyses whereby the discount rate would increase by 100 basis points or the perpetual growth rate would be zero, there are no reasonably possible changes in assumptions that would reduce the value in use below the carrying value of the cash generating unit. F-36 Table of Contents CGU ACTECH The impairment test on the CGU ACTech is based on the discounted cash flows, considering a period of five years. The main assumptions include a discount rate (based on WACC) of 8.04% (11.24% pre-tax) and a perpetual growth rate of 1%. Other assumptions include the year-on-year growth rate of the revenue, gross margin and the operating costs which have been determined by management based on past experience. It was concluded that the value in use is higher than the carrying value of the cash generating unit of K€25,507. Based on the sensitivity analyses performed by the Group, including analyses whereby the discount rate would increase by 100 basis points or the perpetual growth rate would be zero, there are no reasonably possible changes in assumptions that would reduce the value in use below the carrying value of the cash generating unit. CGU Orthoview The goodwill relates to the acquisition of Orthoview. The impairment test on the CGU Orthoview is based on the discounted cash flows considering a period of 5 years.The main assumptions include a discount rate (based on WACC) of 10.27% (13.14% pre-tax) and a perpetual growth rate of 1%. Other assumptions include the year-on-year growth rate of the revenue, gross margin and the operating costs which have been determined by management based on past experience. It was concluded that the value in use is higher than the carrying value of the cash generating unit of K€12,626. Based on the sensitivity analyses performed by the Group, including analyses whereby the discount rate would increase by 100 basis points or the perpetual growth rate would be zero, there are no reasonably possible changes in assumptions that would reduce the value in use below the carrying value of the cash generating unit. The Orthoview business is integrated in the existing software business within our Materialise Medical segment. Synergies that are expected from joined product lines are not taken into account in the current impairment review as management believes that Orthoview can be considered a separate cash generating unit. CGU MAT NV Manufacturing Metal (Aldema) The goodwill related to the acquisition of the Belgian entity Aldema BV in 2015, classified under the CGU Metal Prodution in Belgium. With the Materialise Metal Competence Center established in Bremen, Germany, the Group determined in 2021 that this goodwill balance was fully impaired, resulting in the recognition of a K€177 impairment loss in 2021. CGU Engimplan The impairment test on the CGU Engimplan is based on the discounted cash flows, considering a period of 5 years. The main assumptions include a discount rate (based on WACC) of 19.84% (22.51% pre-tax) and a perpetual growth rate of 8.5%, supported by an expected long term inflation rate of 5%, continued growth opportunities from the increase of the standard of living in Brazil (including access to medical and health care insurances), a growing population in Brazil and export opportunities in Latin America. Other key assumptions include the year-on-year growth rate of the revenue, gross margin and the operating costs which have been determined by both local and Group management based on past experience. At December 31, 2020, the Group recorded a full impairment of the goodwill of K€1,367 as well as a partial impairment on customer lists and trade marks for respectively K€942 and K€207. The impairment test at December 31, 2022, did not indicate the need for a further impairment nor for a reversal of the previously recorded impairment charges. Based on the sensitivity analysis performed by the Group whereby the perpetual growth rate would decrease by 100 basis points, the value in use would be K€361 below the carrying value of the cash generating unit. A perpetual growth rate increase of 100 basis points would bring the value in use K€426 above the carrying value. Based on the sensitivity analysis performed by the Group whereby the discount rate would increase by 100 basis points, the value in use would be K€563 below the carrying value of the cash generating unit. A discount rate decrease by 100 basis points would bring the value in use K€671 above the carrying value. CGU Materialise Motion The impairment test on the CGU Materialise Motion is based on the discounted cash flows, considering a period of five years. The main assumptions include a discount rate (based on WACC) of 9.67% (10.92% pre-tax) and a perpetual growth rate of 5%. Other assumptions include the year-on-year growth rate of the revenue, gross margin and the operating costs which have been determined by management based on past experience. It was concluded that the value in use is higher than the carrying value of the cash generating unit of K€6,187. Based on the sensitivity analyses performed by the Group, including analyses whereby the discount rate would increase by 100 basis points or the perpetual growth rate would be zero, there are no reasonably possible changes in assumptions that would reduce the value in use below the carrying value of the cash generating unit.

The warrants vest for 10% on the second anniversary of the granting; 20% on the third anniversary of the granting; 30% on the fourth anniversary of the granting; and 40% on the fifth anniversary of the granting, unless otherwise decided by the board of directors or one or more of its representatives granted powers thereto. Warrants are exercisable only after they have vested and only during a period of (i) four weeks following the publication of the results of the parent Company of the second and fourth quarter, or (ii) if no quarterly results are published, during the month March and the month September of every year. There are no cash settlement alternatives and the Group does not have a practice of cash settlement for these warrants. The warrants have a term of ten years. The Group granted 350,000 warrants in July 2016 to the employees of the Group with an exercise price of €6.45. The Group granted 2,000 warrants to an employee in May 2018 with an exercise price of €10.08. The status of the 2015 warrant plan at December 31 is as follows: Outstanding at January 1 Granted Forfeited / Cancelled Exercised Outstanding at December 31 Exercisable at December 31 2022 17,400 — — (2,800) 14,600 14,600 2021 133,900 — (2,000) (114,500) 17,400 17,400 2020 310,400 — (6,400) (170,100) 133,900 15,100 With respect to the warrants exercised in 2022, a total of 2,800 warrants representing 2,800 shares were exercised. The share price at exercise date was $8.57. Fair value The fair value of the warrants is estimated at the grant date using the Black-Scholes option pricing model, taking into account the terms and conditions upon which the warrants were granted. The following table provides the input to the Black-Scholes model for the 2013 warrant plan, IPO warrant plan and 2015 warrant plan: Return dividend Expected volatility Risk-free interest rate Expected life Exercise price (in €) Stock price (in €) Fair value warrant (in €) 2015 (Sept 16) 2015 (Nov) IPO 2014 IPO 2014 (Nov) (June) 2013 (Dec) * 2013 (Oct) * — % 47 % 0.24 % 4.30 6.45 6.42 2.41 — % 47 % 1.17 % 5.50 8.81 8.08 3.30 — % 50 % 1.12 % 5.50 8.81 8.67 3.94 — % 46 % 1.70 % 5.50 8.81 8.81 3.83 — % 50 % 2.56 % 5.50 8.54 18.09 12.23 — % 53 % 2.43 % 5.50 7.86 18.09 12.77 (*) Exercise price, stock price and fair value are not adjusted for the 1 to 4 stock-split completed in June 2014. The above input for the Black-Scholes model have been determined based on the following: ● The dividend return is estimated by reference to the historical dividend payments of the Group. Currently, this is estimated to be zero as no dividends have been paid since inception; ● Expected volatility is estimated based on the average annualized volatility of the volatility of the Group’s stock (until September 2016: of a number of quoted peers in the 3D printing industry and the volatility of the Group’s stock); ● Risk-free interest rate is based on the interest rate applicable for the 10Y Belgian government bond at the grant date; ● Estimated life of the warrant is determined to be until the first exercise period which is typically the month after vesting; and F-48 Table of Contents ● Fair value of the shares is determined based on the share price of the Group 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 3-year cash flow projections and a multiple of EBITDA determined based on a number of quoted peers in the 3D printing industry. The expense arising from share-based payment transactions for the warrant plans mentioned above was K€0 in 2022 (2021: K€41; 2020: K€102) The weighted average remaining estimated life of the warrants outstanding as of December 31, 2022 is 2.09 years (2021: 3.13 years; 2020: 4.31 years). The weighted average fair value for the warrants outstanding at the end of 2022 was €3.41 (2021: €3.39; 2020: €3.29). The weighted average exercise price for the warrants outstanding at the end of 2022 was €8.12 (2021: €8.07; 2020: €7.92). Cash-settled share-based payment plans The Group has issued 215,688 SARs in July 2014 towards certain employees in certain countries due to legal requirements with similar terms and conditions as the IPO warrant plan except that the SAR will be settled in cash. The exercise price of the SAR is €8.81. The status of this plan is as follows: Outstanding at January 1 Granted Forfeited / Cancelled Exercised Outstanding at December 31 Exercisable at December 31 2022 11,960 — (632) — 11,328 11,328 2021 37,096 — (1,821) (23,315) 11,960 11,960 2020 71,064 — (5,921) (28,047) 37,096 12,630 The SAR plan grants the bearer the right to a cash payment equal to the difference between the exercise price and the stock price at the exercise date. This plan is considered a cash settled share based payment and is as such recorded as a liability (see Note 16). The SARs have a contractual term of ten years and vest for 25% in the fourth year; 25% in the fifth year; 25% in the sixth year and 25% in the seventh year. SARs are exercisable as from the month after they have vested and in the subsequent exercise periods. The fair value of the SAR is estimated at each reporting date using the Black-Scholes option pricing model, taking into account the terms and conditions upon which the warrants were granted. The following table lists the input used for the Black-Scholes model: Return dividend Expected volatility Risk-free interest rate Expected life Exercise price (in €) Stock price (in €) Fair value SAR (in €) 2022 2021 2020 — % 60 % 3.20 % 0.25 8.81 8.25 0.78 — % 80 % 0.18 % 0.25 8.81 21.05 12.26 — % 84 % (0.34)% 0.25 8.81 44.20 35.38 The expense arising from share-based payment transactions for the SARs plan was K€(140) in 2022 (2021: K€(874) ;2020: K€1,242). The carrying value of the liability at December 31, 2022 amounts to K€9 (2021: K€147; 2020: K€1,223). The total intrinsic value of the liability for warrants currently exercisable at December 31, 2022 amounts to K€9 (2021: K€147; 2020: K€447). Share-based payment plans of RapidFit+ The subsidiary RapidFit+ has issued a warrant plan on August 23, 2013 where a maximum of 300 warrants can be offered to management with an exercise price of €553.90. In January 2014, a total of 199 warrants were granted and accepted.

F-50 Table of Contents K€35,000 EIB bank loan On December 20, 2017 the Group entered into a finance contract with the European Investment Bank, or EIB, to finance future research and development programs. As part of a first tranche, an amount of K€10,000 was drawn in the course of 2018. The agreement foresees a first two-year period without loan reimbursements. Loans under the contract are made at a fixed rate, based on the Euribor rate at the time of the borrowing, plus a variable margin. The interest rate for this loan is 2.40%. The contract contains customary security, covenants and undertakings. A second tranche of K€25,000 was drawn in the course of 2019 with an interest rate of 2.72%. Pledges have been given on moveable assets as well as over the shares. On June 29, 2020, the European Investment Bank temporarily waived the compliance obligation of the covenants “Total gross Debt to Adjusted EBITDA” (until December 31, 2022), and “Adjusted EBITDA to Net financial charges” (until 31 December 2020) under the condition that the covenant “Total net debt to Adjusted EBITDA” will be met for the period. In addition, the European Investment Bank agreed not to recalculate the interest rate until January 3, 2022 for the first tranche and until January 17, 2022 for the second tranche. Finally, the European Investment Bank waived “the subsidiary financial indebtedness” covenant for the calculation period ending on June 30, 2020. For the periods thereafter this covenant has been eased. These covenants were waived in order to allow the Group to continue investing in its growth programs, even under stressed COVID-19 scenarios. At December 31, 2022, The Group was in compliance with all debt covenants. K€28,000 Acquisition loan This bank loan has been concluded in October 2017 to finance the acquisition of ACTech.

Their fair value is not different from their carrying value on December 31, 2022, 2021 and 2020 ● Other non-current financial assets are being evaluated on the basis of their credit risk and interest rate which are considered as level 2 inputs. Their fair value is not considered different from their carrying value given the related interest rate is revised on a regular basis. ● The non-listed equity investments, mainly representing the investment AM Flow (via an investment in AM Danube, one of the shareholders of AM Flow) for K€307, are measured at fair value. As of December 31, 2022, management considers that currently the cost is an appropriate estimate of fair value (level 2 input) because the most recent capital increase indicated that the market valuation of AM Flow has not changed and because of the followings reasons: ◾ AM Flow is a non-listed entity; ◾ The Group only has an insignificant interest in AM Flow BV (approx. 5% of the shares indirectly); ◾ The Group has no representatives in the Board of Directors of AM Flow BV; and ◾ Insufficient more recent information is available to measure fair value; ● For the non-listed equity investment in Essentium, as of December 31, 2021, Materialise recorded a remeasurement of fair value to zero through OCI (K€3,443). ● The convertible loan granted to Fluidda is measured at fair value. As of December 31, 2022, management determined the fair value based upon level 3 inputs as follows: ◾ The Group determined that the fair value of the convertible loan as of December 31, 2022 amounted to K€3,494. Fluidda is a private start-up company which offers turnkey contract research services for drug development and medical device development. Fluidda is currently loss-making. The convertible loan has a duration of 7 years with a 10% annual interest rate which are capitalized. The Group has applied a discount factor of 12.67% that is based on the estimated WACC of Fluidda reflecting the uncertainty in relation to the success of the company and the applied estimates by the Group. F-54 Table of Contents In assessing the fair value, the Group has made significant estimates with regard to the discount rate, the probability of each repayment and conversion scenario and related timing, the amount of the qualified capital increase. Changes in the significant assumptions may lead to a significant increase/decrease in the fair value of the convertible loan. A increase/decrease in the applied discount rate for Fluidda by 1% would lead to a change in fair value by K€(61) / K€63. Financial liabilities: The carrying value and fair value of the financial liabilities as of December 31, 2022, 2021 and 2020 can be presented as follows: in 000€ Financial liabilities measured at amortized cost Loans & Borrowings including lease liabilities Trade payables Other liabilities excl. written put option on NCI Total financial liabilities measured at amortized cost Financial liabilities measured at fair value Contingent consideration Cash settled share based payments Written put option on NCI Derivatives Total financial liabilities measured at fair value Total non-current Total current 2022 Carrying value 2021 2020 2022 Fair value 2021 2020 80,980 23,230 330 78,848 100,417 116,843 17,698 20,171 23,230 1,275 485 330 104,540 119,764 134,084 102,408 121,073 135,816 99,108 115,110 17,698 20,171 1,276 485 — — — — 9 — — 9 61,020 43,529 — 147 — 118 265 79,905 40,124 — 1,223 875 140 2,238 98,543 37,779 The fair value of the financial liabilities has been determined on the basis of the following methods and assumptions: ● The carrying value of current liabilities approximates their fair value due to the short term character of these instruments; ● Loans and borrowings are evaluated based on their interest rates and maturity date. Most interest bearing debts have fixed interest rates and their fair value is subject to changes in interest rates and individual creditworthiness; ● The fair value of the derivatives has been determined based on a mark-to-market analysis prepared by the bank based on observable market inputs (level 2 inputs); ● The fair value of the written put option on non-controlling interest has been determined based on the present value of the redemption amount (level 3 inputs); ● The fair value of the cash-settled share based payments has been determined based on a Black-Scholes model using inputs that are level 1 (stock-price and risk-free interest rate) as well as level 2 (e.g. volatility).

The Group has the following financial instruments carried at fair value in the statement of financial position on December 31, 2022, 2021 and 2020: the derivatives related to interest rate and foreign currency swaps as included in the above tables, a call option and written put option on non-controlling interest and the non-listed equity investments. 21 Segment information For management purposes, the Group is organized into segments based on their products, services and industry and has the following three reportable segments: ● The Materialise Medical segment, which develops and delivers medical software solutions, medical devices and other related products and services; ● The Materialise Manufacturing segment, which delivers 3D printed products and related services; and ● The Materialise Software segment, which develops and delivers additive manufacturing software solutions and related services. The measurement principles used by the Group in preparing this segment reporting are also the basis for segment performance assessment and are in conformity with IFRS. The Chief Executive Officer of the Group acts as the chief operating decision maker. As a performance indicator, the chief operating decision maker controls the performance by the Group’s revenue and adjusted EBITDA. The following table summarizes the segment reporting for each of the reportable periods ending December 31. Corporate research and development, headquarters’ function, financing and income taxes are managed on a Group basis and are not allocated to operating segments. As management’s controlling instrument is mainly revenue-based, the reporting information does not include assets and liabilities by segment and is as such not available per segment. in 000€ For the year ended December 31, 2022 Revenues Segment Adjusted EBITDA Segment Adjusted EBITDA % For the year ended December 31, 2021 Revenues Segment Adjusted EBITDA Segment Adjusted EBITDA % For the year ended December 31, 2020 Revenues Segment Adjusted EBITDA Segment Adjusted EBITDA % Materialise Materialise Materialise Software Medical Manufacturing Total segments Unallocated Consolidated 43,688 1,514 84,846 18,822 103,489 8,229 232,023 28,565 3.5 % 22.2 % 8.0 % 12.3 % — (9,551) — 232,023 19,014 8.2 % 42,902 15,705 73,368 20,669 89,180 6,275 205,450 42,649 36.6 % 28.2 % 7.0 % 20.8 % — (10,159) — 205,450 32,490 15.8 % 39,054 13,383 61,729 13,915 69,635 2,548 170,418 29,846 34.3 % 22.5 % 3.7 % 17.5 % 31 (9,468) — 170,449 20,378 12.0 % F-56 Table of Contents The segment Adjusted EBITDA is reconciled with the consolidated net profit (loss) for the year as follows: in 000€ Net profit (loss) for the year Share in loss of joint venture Income taxes Financial income Financial expenses Operating (loss)/ profit Impairments Fair value adjustment 50% Materialise Motion Other operating income (expense) Corporate headquarter costs Corporate research and development Depreciation, amortization and impairment Segment Adjusted EBITDA For the year ended December 31, 2021 13,145 — 591 (5,620) 4,101 12,217 177 — (3,527) 10,317 2,948 20,516 42,649 2022 (2,153) — 975 (6,114) 4,420 (2,872) — — (2,693) 9,504 2,600 22,026 28,565 2020 (7,193) 39 (1,028) (2,452) 5,995 (4,639) 4,606 (770) (3,668) 11,719 2,824 19,775 29,847 The Group has 1 individual customer that represents sales larger than 10% of the total revenue in 2022 (2021: 1; 2020: 0).

Note 18 includes a split of the deferred income in current and non-current. Non- current deferred income, representing mainly maintenance contracts with terms more than one year and certain contracts with up-front fees which are allocated to performance obligations that will be satisfied over more than one year, may be recognized as revenue between one to three years. Total revenue recognized during 2022 that was included in the contract liability at the beginning of the year amounts to K€39,324. There is no revenue recognized during 2022 from performance obligations that were satisfied in the previous years. The relation between the timing of satisfaction of the performance obligations and the timing of billing resulting in contract assets and liabilities is as follows: ● Maintenance services: maintenance services are typically billed at the beginning of the maintenance period resulting in deferred income that is recognized on a straightline basis over the maintenance period. ● Software licenses: certain software licenses may have been billed prior to the delivery of the software key or time-based software licenses may have been billed up-front resulting in a deferred income balance. ● Certain agreements in the medical segment include up-front fees such as step-in fees or milestone payments which are billed at inception of the contract but which are allocated to performance obligations which are satisfied at a later time in the contract term or which have not been recognized considering the revenue constraint (i.e. may have to be credited when customer achieves certain volume targets). In addition, certain contracts include prepaid fees for volume “Plan Only” purchases for which the purchased services are only delivered during a one year period. Those fees result in deferred income which are recognized as revenue when services/products are delivered and revenue is not constrainted. ● Certain development services are satisfied while the services can only billed at certain pre-defined points in time or when the services are fully satisfied resulting in contracts in progress / contract assets. 22.2 Cost of sales Cost of sales includes the following selected information: in 000€ Purchase of goods and services Amortization and depreciation Payroll expenses Work in Progress Total F-59 For the year ended December 31 2021 (38,691) (11,296) (38,499) 1,208 (87,278) 2022 (51,597) (11,174) (42,718) 2,234 (103,255) 2020 (31,725) (11,788) (32,438) (495) (76,446) Table of Contents 22.3 Research and development expenses Research and development expenses include the following selected information: in 000€ Purchase of goods and services Amortization and depreciation Payroll expenses Other Total 22.4 Sales and marketing expenses Sales and marketing expenses include the following selected information: in 000€ Purchase of goods and services Amortization and depreciation Payroll expenses Other Total 22.5 General and administrative expenses General and administrative expenses include the following selected information: in 000€ Purchase of goods and services Amortization and depreciation Payroll expenses Other Total 22.6 Net other operating income The net other operating income can be detailed as follows: in 000€ Government grants Amortization intangibles purchase price allocation Allowance for doubtful debtors Capitalized expenses (asset construction) Tax Credits Fair value adjustment Materialise Motion Impairment Engimplan Impairment Metal Belgium (Aldema) Indemnity fee from commercial agreement COVID support Germany Other Total For the year ended December 31 2021 (3,770) (1,821) (21,300) — (26,891) 2022 (5,930) (1,454) (30,184) — (37,568) 2020 (2,788) (1,746) (20,368) (2,202) (27,104) For the year ended December 31 2021 (6,704) (1,892) (40,555) — (49,151) 2022 (11,802) (2,541) (47,782) — (62,125) 2020 (5,960) (1,946) (36,521) (209) (44,636) For the year ended December 31 2021 (11,248) (2,987) (19,080) — (33,315) 2022 (6,240) (1,710) (27,193) — (35,143) 2020 (8,933) (2,437) (18,104) 137 (29,337) For the year ended December 31 2021 2020 2022 4,932 (5,146) 390 — 887 — — — 506 681 946 3,196 4,466 (2,521) (58) 223 746 — — (177) — — 723 3,402 4,473 (1,857) (244) 316 1,198 770 (2,516) — — — 295 2,436 The Company has received government grants from the Belgian federal and regional governments and from the European Community in the forms of grants linked to certain of its research and development programs and reduced payroll taxes.

With respect to the unused tax losses and Innovation Income Deduction of Materialise NV, we recognized a deferred tax asset of € 0.2 million as at December 31, 2022. No deferred tax assets were recognized in respect of these carry-overs as at December 31, 2021 or December 31, 2020. Under the Belgian Innovation Income Deduction system, companies can deduct up to 85% of their net innovation income from the taxable basis. Based on its analysis, the Group determined that no additional deferred tax assets should be recognized with respect to unused tax losses and Innovation Income Deduction carried forward at the level of Materialise NV, other than as described above, as at December 31, 2022. With respect to the unused tax losses of the other entities, we carried as at December 31, 2022 a deferred tax asset of € 1.6 million for Materialise USA related to losses carried forward from the acquired entities Link3D and Identify3D. No deferred tax assets were recognized in respect of unused tax losses carried over at the level of other entities as at December 31, 2021 or 2020, except for our tax unity in Germany where we recorded a deferred tax asset of € 0.3 million related to 2020 losses and Materialise Motion where we recorded a deferred tax asset of € 1.8 million against a deferred tax liability of € 2.0 million. The deferred tax liability of K€6,700 as at December 31, 2022 mainly relates to the intangibles that have been recognized in connection with business combinations (ACTech, Materialise Motion, Link3D and Identify3D).

If there is a net loss after taxes, the number of diluted shares is equal to the basic shares.

The carrying value of related property, plant & equipment (including buildings under construction) is K€23,560 (2021: K€25,582; 2020: K€27,638). The total outstanding mortgages and pledges are K€100,978 in 2022 (2021: K€103,685; 2020: K€105,610). Included in the above, the Group also has pledges on the business goodwill (“fonds de commerce”) of the Company for a total amount of K€69,300 in 2022 (2021: K€69,300; 2020: K€69,300) and pledges on other fixed assets for a total amount of K€442 (2021: K€1,399; 2020: K€3,290). Other commitments The Group has outstanding non-cancellable contracts with a future commitment of K€25,385 at December 31, 2022 (2021:K€7,043; 2020:K€6,384), mainly related to purchase commitment for raw materials and energy and gas. For property, plant & equipment, we have no committed expenditures as per December 31, 2022 (2021: K€0; 2020: K€0). Contingent liabilities On June 1, 2021, we entered into a settlement agreement with Osteoplastics, LLC in connection with a patent infringement lawsuit filed by Osteoplastics, LLC on March 20, 2020, as described in our Annual Report on Form 20-F for the year ended December 31, 2020. Pursuant to the settlement agreement, we agreed to file documents seeking to withdraw or terminate all petitions for review (the “IPR Procedure”) of seven asserted patents owned by Osteoplastics, LLC with the Patent Trial and Appeal Board of the United States Patent and Trademark Office (the “PTAB”). On June 3, 2021, we filed a Motion to Dismiss with the PTAB regarding the IPR Procedure, and in a decision dated June 4, 2020, the PTAB granted our Motion to Dismiss. Other than external counsel fees and PTAB fees, there was no financial impact incurred in relation to this matter or the settlement agreement. On September 21, 2021, the Brussels Court of Appeal issued a judgment regarding the termination of a supply agreement that we entered into with Dentsply Implants NV in 2010. In its judgment, the Court of Appeal overruled the judgment issued by the court of first instance (which had previously ruled in favor of Dentsply Implants NV), and fixed the amount of the financial compensation to Dentsply Implants NV at an amount, which, increased with legal interests and costs, resulted in a total amount payable by us to Dentsply Implants NV of € 866,909.74. This judgment of the Brussels Court of Appeal is final and payment was made on November 25, 2021. On November 15, 2021, we received a written notice from counsel for Zimmer Biomet, informing us of Zimmer Biomet’s decision to file a request for arbitration with the Belgian Centre for Arbitration and Mediation. Zimmer Biomet believes that we have a contractual obligation pursuant to the terms of our collaboration to indemnify Zimmer Biomet for the expenses it incurred as a result of its settlement with Conformis, Inc. of a patent dispute related to certain joint replacement devices. We believe there are meritorious defenses to Zimmer Biomet’s claim and intend to contest it vigorously. However, an adverse resolution of this arbitration could have an adverse effect on our results of operations, financial condition or cash flows in the period in which the arbitration is resolved. No amounts have been accrued for this loss contingency. A final arbitral award is scheduled to be issued at the latest on May 2, 2023. Apart from the cases set out above, the Group is currently not a party to any other legal or arbitration proceedings, which, in the opinion of the management, is likely to have or could reasonably possibly have a material adverse effect on the business, financial position or results of operations. 25 Risks The Group is mainly exposed to liquidity risk, interest rate risk and credit risk. Foreign exchange risk The Group transacts business globally and is subject to risks associated with fluctuating foreign exchange rates. The geographic areas outside of the Eurozone to which it sells its products and services are generally not considered to be highly inflationary. In the years ended December 31, 2022, 2021 and 2020, 39%, 35% and 35% of our revenue, respectively, were derived from sales in a currency F-64 Table of Contents 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. The Group has primarily exposure to the USD, GBP, BRL, PLN and JPY as foreign currency. The exposure on MYR and CZK is limited. There is only a limited portion of turnover in local currency. If the U.S. dollar (rate for €1) would have appreciated by 10%, the net result would have been € 0.9 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 € 0.7 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 GBP, the Group has entered into currency rate swaps. As of December 31, 2022 the Group had hedge agreements in place for K £800. We refer to note 20 for the related fair value of these derivatives. Inflation risk We transact business globally and are subject to risks associated with fluctuating inflation. The risk exists that if inflation rises to levels that our selling prices can’t be aligned timely to offset the rise of cost of remuneration, materials, services, energy, and capital expenditure. For the first time since the banking crisis in 2008, inflation in several of our main markets has increased by more than 5% in the year ended December 31, 2022. Although we succeeded to increase our selling prices in various business lines, we experienced negative effects where cost increased could not be offset completely or timely by selling pricing adjustments. If inflation would not stabilize at a lower level than in 2022, this may adversely affect our results of operations and financial condition. Liquidity risk The liquidity risk is that the Group may not have sufficient cash to meet its payment obligations. This risk is countered by day-by-day liquidity management at the corporate level. The Group has historically entered into financing and lease agreements with financial institutions to finance significant projects and certain working capital requirements. At December 31, 2022, we held cash and cash equivalents of € 140.9 million, while €20.0 million of our € 81.0 million gross debt was short term. At December 31, 2022, we had an undrawn credit line of € 50 million as more fully described in Note 15 to the consolidated financial statements. The range of contracted obligations are as follows (incl. interest): in 000€ At December 31, 2022 Loans & borrowings Lease liabilities Trade payables Other current liabilities Total Less than 1 year 2 to 3 years 4-5 years More than 5 years Total 18,156 3,080 23,230 339 44,805 35,131 2,725 — — 37,856 15,017 1,289 — — 16,306 8,627 1,425 — — 10,052 76,931 8,519 23,230 339 109,019 F-65 Table of Contents At December 31, 2021 Loans & borrowings Lease liabilities Trade payables Other current liabilities Total At December 31, 2020 Loans & borrowings Lease liabilities Trade payables Other current liabilities Total Interest rate risk Less than 1 year 2 to 3 years 4-5 years More than 5 years Total 19,081 3,496 20,171 750 43,498 41,590 3,790 — — 45,380 19,587 946 — — 20,533 14,901 1,102 — — 16,003 95,159 9,334 20,171 750 125,414 Less than 1 year 2 to 3 years 4-5 years More than 5 years Total 15,335 3,831 17,698 3,798 40,662 36,819 4,850 — — 41,669 34,928 1,570 — — 36,498 23,565 1,420 — — 24,985 110,647 11,671 17,698 3,798 143,814 Although the Group mainly has 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 the Group is not subject to immediate changes in interest rates. Credit risk Credit risk is the risk that third parties may not meet their contractual obligations resulting in a loss for the Group. The Group is exposed to credit risk from its operating activities (primarily trade receivables) and from its financing activities, which are mainly deposits with financial institutions. The Group limits 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. Trade receivables and contracts in progress Customer credit risk is managed by each business unit subject to the Group’s established policy, procedures and controls relating to customer credit risk management. An impairment analysis is performed at each reporting date per company and using a provision matrix per company to measure expected credit losses. 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 through OCI as disclosed in Note 20. The Group does not hold collateral as security. The Group evaluates the concentration of risk with respect to trade receivables as low, as its customers are located in several jurisdictions and industries and operate in largely independent markets.

Capital is defined as the Group shareholder’s equity. The Group consistently reviews its capital structure and makes adjustments in light of changing economic conditions. The Group made no changes to its capital management objectives, policies or processes during the years ended December 31, 2022, 2021 and 2020. 26 Related party transactions The compensation of key management personnel of the Group is as follows: in 000€ Short-term employee benefits Post-employment benefits Total Warrants granted Warrants outstanding For the year ended December 31 2021 2020 2022 2,736 75 2,811 — — 2,832 93 2,925 — 4,545 2,302 93 2,395 — 108,905 The amounts disclosed in the table are the amounts recognized as an expense during the reporting period related to key management personnel (senior management and executive committee members).

Capital ARTICLE 5: Capital and shares The registered capital amounts to four million four hundred eighty-seven thousand fifty and forty-nine cents (4,487,050.49 EUR), represented by fifty-nine million sixty-seven thousand one hundred eighty-six (59,067,186) shares, without designation of nominal value, each representing an equal share in the capital. The capital has been subscribed to and paid up in full and unconditionally. ARTICLE 6: Authorized capital a) By decision of the general meeting of shareholders of 5 November 2020, which will enter into force on the day of publication of the decision in the Annexes to the Belgian Official Gazette, the Board of Directors was granted the authority to increase the share capital in one or more rounds up to a maximum total amount equal to four million sixty-seven thousand seven hundred euro and seventy-two cents (4,067,700.72 EUR). The Board of Directors may only exercise the powers granted to it for a period of five (5) years from the publication of this authorisation in the Annexes to the Belgian Official Gazette. This authorisation may be renewed in accordance with the applicable legal conditions. The Board of Directors has not yet exercised the authority granted to it. b) The capital increases decided upon pursuant to this authorisation may take place in accordance with the conditions to be determined by the Board of Directors, including: · · · · · · · · · by means of contributions in cash or in kind within the limits permitted by the Belgian Companies and Associations Code, through a conversion of reserves and share premiums, with or without the issue of new securities, through the issue of shares, with or without voting rights, through the issue of convertible bonds, whether subordinated or not, through the issue of subscription rights (free of charge or at a certain issue price), through the issue of bonds to which subscription rights or other securities are attached, through the issue of other securities, such as shares under a stock option plan, through the issuance of shares below fractional value. c) As far as needed and applicable, in the event of a public takeover bid for securities issued by the company, the Board of Directors shall also have a specific authorisation to increase the capital in any form whatsoever, including a capital increase in which the shareholders’ preferential subscription right is restricted or suspended, under the conditions provided for in Article 7:202 of the Belgian Companies and Associations Code. This authorisation is granted for a period of three (3) years, starting from the extraordinary general meeting of shareholders held on 5 November 2020. This authorisation may be renewed for the same period by a decision of the general meeting made in accordance with the rules set for the amendment of the articles of association. The capital increases decided upon in the context of this authorisation shall be imputed to the remaining part of the authorised capital as referred to in paragraph (a). d) Any issue premiums payable at the time of subscription to a capital increase within the framework of the authorised capital shall be booked to a separate account under shareholders’ equity in the liabilities section of the Company’s balance sheet and shall be constituted by contributions in cash or in kind, other than contributions in work, actually paid up at the occasion of the issuance of shares. e) The Board of Directors shall also be authorised to restrict or cancel the preferential subscription right in the interest of the company. It may do this for the benefit of one or more specific persons, even if they are not members of the personnel of the company or its subsidiaries, provided that, including upon the issue of subscription rights, compliance with the relevant legal provisions is ensured. It may also decide, as appropriate, to give priority to the existing shareholders during the allocation of new shares. f) The Board of Directors has the power, with the possibility of subrogation, to amend the articles of association of the company in order to align them with decisions on capital increases within the framework of the authorised capital. On June 9, 2021, the company's board of directors decided to increase the company's share capital, by contribution in kind, within the framework of the authorized capital, the first partial realization of which was adopted on June 14, 2021 at an amount for the capital increase of three hundred twenty thousand euros (320,000.00 EUR), bringing the available amount of the authorized capital to three million seven hundred forty-seven thousand seven hundred euros and seventy-two cents (3,747,700.72 EUR). A second and final partial realization was established on July 6, 2021 at an amount for the capital increase of forty-eight thousand euros (48,000.00 EUR), bringing the available amount of authorized capital to three million six hundred ninety-nine thousand seven hundred euros and seventy-two cents (3,699,700.72 EUR). ARTICLE 7: Capital increase - preferential subscription right. a) Subject to the possibility of a capital increase within the framework of authorized capital by decision of the Board of Directors, an increase in the share capital can only be decided upon by an extraordinary general meeting before a notary public, in accordance with the provisions of the Belgian Companies and Associations Code. b) For each capital increase by means of a contribution in cash, the shareholders shall have a preferential subscription right in accordance with Article 7:188 et seq. of the Belgian Companies and Associations Code and the new shares, convertible bonds and subscription rights shall first be offered to the existing shareholders in proportion to the part of the capital represented by their shares. The period during which the preferential subscription right may be exercised shall be determined by the general meeting of shareholders or, as applicable, by the Board of Directors, and may not be less than fifteen days from the date on which the subscription is opened. The Board of Directors may decide that the total or partial non-use by the shareholders of their preferential subscription rights shall increase the proportional share of the shareholders who have already exercised their preferential subscription rights; it shall also decide on the subscription procedure. The Board of Directors shall also have the right, upon such terms as it shall determine, to conclude all agreements to ensure the subscription to all or part of the shares to be issued. If a share is encumbered with a usufruct, the preferential subscription right shall belong to the usufructuary, unless otherwise agreed. The newly acquired shares, convertible bonds and subscription rights shall be fully owned by him, subject to a possible fee paid to the bare owner for exercising the preferential subscription right. In the case of pledged shares, the preferential subscription right shall exclusively belong to the owner-pledger. In the interest of the company and with due observance of the relevant legal requirements, the general meeting of shareholders and, within the framework of the authorized capital, the Board of Directors, may restrict or cancel the preferential subscription right. c) The general meeting of shareholders, or the Board of Directors within the authorized capital, as appropriate, may decide to increase the capital in favour of its employees, subject to the provisions of Article 7:204 of the Belgian Companies and Associations Code. d) A capital increase can also be realized through the conversion of reserves. The extraordinary general meeting may grant the Board of Directors the power to increase the capital within the limits of the authorized capital through the conversion of reserves. ARTICLE 8: Capital reduction A decision to reduce the capital can be made in accordance with the relevant legal provisions. 3. Shares and other securities ARTICLE 9: Nature of the securities The shares and other securities of the company are and will always remain registered shares. They shall bear a serial number. A register is kept at the registered office of the company for each class of registered securities, either in original physical form or in electronic form in accordance with the applicable legislation. The ownership of registered securities is determined by an entry in the register. If so requested, certificates of these subscriptions shall be issued to the holders of the securities. ARTICLE 10: Unpaid or partially paid shares—obligation to pay up The obligation to pay up a share is unconditional and indivisible. If shares which have not been paid up in full are jointly owned by several persons, each one of them shall be liable for the payment of the entire amount of the duly called payments due. Additional contributions or full payment are requested by the Board of Directors at a time to be determined by the Board of Directors. The shareholders are notified in accordance with article 2:32 of the Belgian Companies and Associations Code, which shall mention the bank account to which payment must be made by wire transfer or deposit, with the exclusion of all other methods of payment. The shareholder shall be deemed in default when the time limit specified in the notice has expired and interest shall be payable to the company at the statutory rate fixed at that time, plus two percentage points. As long as the called payments due for a share have not been made in accordance with this provision, the exercise of the rights related thereto shall be suspended. Early payments on shares may not be made without the prior consent of the Board of Directors. ARTICLE 11: Indivisibility of shares The securities are indivisible vis-à-vis the company. If multiple persons have a right in rem to the same security, they may exercise the rights attached to such securities only through a joint representative. The company may suspend the exercise of the rights attached to it until a single person has been appointed as the owner of the security vis-à- vis the company or as their joint representative. All convocation notices, notifications and other notices served by the company to the different persons entitled to a single security shall be validly and exclusively given, as the case may be, either to the person designated as the owner vis-à-vis the company or to the designated joint representative. Unless stipulated otherwise in the articles of association, a will or an agreement, the usufructuary of the securities shall exercise all rights attached to these securities. ARTICLE 12: Successors The rights and obligations shall remain attached to a security, regardless of its ownership. The heirs, creditors or other successors of the shareholder may not interfere with the management of the company, nor cause any seals to be affixed to the goods and valuables of the company, nor claim the liquidation of the company and the distribution of its equity. They shall act in compliance with the company’s financial statements for exercising their rights and shall observe the decisions of the general meeting and the Board of Directors. ARTICLE 13: Bonds, subscription rights and other financial instruments granting rights to shares The company may issue bonds by decision of the Board of Directors, which will determine the terms of the issue. The issue of convertible bonds or bonds redeemable in shares, subscription rights or other financial instruments which will eventually entitle the holder to shares may be decided upon by the general meeting of shareholders or by the Board of Directors within the framework of the authorized capital (subject to compliance with the relevant legal requirements). The holders of shares without voting rights, profit-sharing certificates without voting rights, convertible bonds, subscription rights or certificates which were issued with the cooperation of the company, may attend the general meeting of shareholders, but only in an advisory capacity. 3. Acquisition and disposal of own securities ARTICLE 14: Acquisition and disposal of own securities a) The company may acquire its own shares or profit participation certificates or certificates relating thereto, or subscribe for them, after the issue of the corresponding shares or profit participation certificates, in accordance with the relevant legal provisions. b) By decision of the general meeting of shareholders of 5 November 2020, the Board of Directors was authorized, in accordance with Article 7:215 et seq. of the Belgian Companies and Associations Code and within the limits specified in this article, to acquire its own shares at a price per share that may not be lower than 80%, and not higher than 120% of the average closing prices of the American Depository Shares representing the shares of the company during a period of 30 calendar days prior to either the date of purchase or the date of announcement thereof. This authorisation shall also apply to the acquisition of the company’s shares by one of its directly controlled subsidiaries, as referred to in and within the limits of Article 7:221 of the Belgian Companies and Associations Code. Any offer to acquire the company’s shares must be made to all shareholders under the same conditions, in accordance with Article 7:215, 1st paragraph, 4th section of the Belgian Companies and Associations Code. This authorisation shall be valid for a period of five years from the publication of this authorisation in the Annexes to the Belgian official gazette. This authorisation may be extended by a decision of the general meeting and in accordance with the provisions of the Belgian Companies and Association Code. c) The Board of Directors may only dispose of its acquired shares, profit participation certificates or certificates relating thereto in accordance with the relevant legal provisions and this at a price determined by the Board of Directors. Without prejudice to the foregoing, the Board of Directors is specially authorised to alienate its acquired shares, profit participation certificates or certificates relating thereto (i) to one or more specific persons other than the personnel (in this case, the directors who in fact represent this person or the persons associated with him, may not participate in the vote of the Board of Directors), and (ii) to the personnel. The foregoing also applies to the disposal of the shares of the Company by one of its direct subsidiaries in accordance with Article 7:221 of the Companies and Associations Code. c) By decision of the general meeting of shareholders of 5 November 2020, the Board of Directors was authorised, without further decision by the general meeting of shareholders and in accordance with the provisions of the Belgian Companies and Associations Code, to acquire or dispose of the company’s shares, when such acquisition or disposal is necessary to prevent serious imminent harm to the company. This authorisation is granted for a period of three years, starting from the publication of this authorisation in the Annexes to the Belgian Official Gazette. This authorisation may be extended for periods of three years by a decision of the general meeting and in accordance with the provisions of the Belgian Companies and Associations Code. 4. Management and representation ARTICLE 15: Appointment—Dismissal—Vacancy—Publication a) The Board of Directors of the company shall consist of at least seven (7) and no more than eleven (11) directors, and at least three (3) directors must be independent directors (within the meaning of Article 7:87 of the Belgian Companies and Associations Code). b) As long as all the voting rights attached to the shares controlled by each of the Family Shareholders, whether directly or indirectly and jointly or otherwise, represent 20% or more of all voting rights attached to all outstanding shares of the company, a maximum of six (6) directors shall, if a Family Shareholder makes a simple request to that end, only be appointed on the nomination of a majority of all Family Shareholders who directly or indirectly control at least 3% of the voting rights attached to the shares of the company on the date of the appointment. The number of candidates on the nomination list of the Family Shareholders must be higher than the number of vacancies to be filled which are subject to the nomination right. If a director appointed on the nomination of the Family Shareholders resigns or is dismissed, his vacancy may only be filled by a candidate nominated by the majority of the other directors appointed on the nomination of the Family Shareholders, if any. For the purposes of this Article, “Family Shareholders” shall include the following persons: Wilfried Vancraen, Hilde Ingelaere and their relatives in the first degree in descending line. c) When a legal entity is appointed as a director, it will appoint a physical person as a permanent representative who will be charged with the execution of the assignment in the name of and on behalf of the legal entity-director. d) The directors are appointed by the general meeting of shareholders. In any case, the duration of their assignment may not exceed the maximum legal term of six (6) years. Their assignment shall end when the general meeting of shareholders or the meeting of the Board of Directors deciding on their replacement is closed. The directors can be dismissed by the general meeting of shareholders at all times. Retiring directors are eligible for reappointment. e) When a director’s office becomes vacant, the remaining directors have the right to co-opt a new director under the conditions provided for by law and in compliance with the abovementioned nomination scheme. The subsequent general meeting of shareholders must confirm the mandate of the co- opted director; in case of confirmation, the co-opted director fulfills the mandate of his predecessor, unless the general meeting decides otherwise. In the absence of confirmation, the mandate of the co-opted director ends at the end of the general meeting, without prejudice to the regularity of the composition of the Board of Directors until that time. f) The Chairman of the Board of Directors will be elected by the Board of Directors. g) The appointment of the members of the board and the termination of their office shall be published by submitting an extract from the decision at the Registrar’s Office of the Commercial Court in the company file, and a copy thereof for publication in the Annexes to the Belgian Official Gazette. These documents shall in any event specify whether the persons representing the company each bind the company individually, jointly or as a body. ARTICLE 16: Convocation of the Board of Directors a) The Board of Directors shall be convened by its chairman as often as required in the interest of the company, and shall meet within fourteen days following a request to that effect from two directors or from the managing director.

The Board of Directors is authorized to take any action which is required or useful to pursue the company’s object, with the exception of the activities assigned exclusively to the general meeting by law. b) Without prejudice to the obligations arising from collegial management, in particular with respect to consultation and supervision, the directors may distribute the management tasks among themselves. Such division of tasks shall not be enforceable against third parties. c) The Board of Directors may establish one or more advisory committees under its responsibility.

None of the aforementioned parties can claim a priority over the others. The directors independently and discretionary weigh the various interests that may serve the realisation of the aforementioned positive impact as part of the corporate interest. Under no circumstances does this provision confer any right, either explicitly or implicitly, on stakeholders or other third parties.

Such a request must be sent by registered letter to the registered office of the company; it must state the agenda items on which the general meeting has to deliberate and decide. The notice convening the general meeting to be held must be given within three weeks of the request.

If they wish to attend, they shall be bound by the same formalities of admission, access, form and notification for proxies as those imposed on the shareholders. ARTICLE 28: Chairman—Committee Each general meeting is presided by the chairman of the Board of Directors or, in his absence, by the vice-chairman (if one has been appointed) or by the oldest member of the Board of Directors. The chairman shall appoint a secretary and vote counter, who does not have to be a shareholder. Both roles may be performed by one person.

The directors and possible auditor(s) can, in the interest of the company, refuse to answer questions when the communication of certain data or facts could be detrimental to the company or would be in contravention of confidentiality commitments entered into by them or by the company. As soon as the convocation notice has been published, the shareholders may ask the abovementioned questions (in writing or by e- mail), provided that these shareholders meet the conditions to be admitted to the meeting and that they have submitted their questions to the company at the latest on the third (3rd) business day prior to the date of the scheduled meeting as specified in the convocation notice. b) During the session, the Board of Directors has the right to postpone each general shareholders’ meeting by three weeks.

ARTICLE 33: Appropriation of profits—Reserve The positive balance of the profit and loss account shall constitute the profits of the company. Of these net profits, at least one twentieth is deducted in advance to constitute the legal reserve until it amounts to one tenth of the share capital.
