SPECIAL NOTE REGARDING FORWARD-LOOKING INFORMATION

This  annual  report  includes  certain  forward-looking  statements  within  the  meaning  of  Section  27A  of  the  Securities  Act  of  1933,  as
amended, or the Securities Act, and Section 21E of the Securities Exchange Act of 1934, as amended, or the Exchange Act, concerning
our  business,  operations  and  financial  performance  and  condition  as  well  as  our  plans,  objectives  and  expectations  for  our  business
operations and financial performance and condition. Any statements that are not of historical facts may be deemed to be forward-looking
statements.  You  can  identify  these  forward-looking  statements  by  words  such  as  “believes,”  “estimates,”  “anticipates,”  “expects,”
“plans,”  “intends,”  “may,”  “could,”  “might,”  “will,”  “should,”  “aims,”  or  other  similar  expressions  that  convey  uncertainty  of  future
events  or  outcomes.  Forward-looking  statements  appear  in  a  number  of  places  throughout  this  annual  report  and  include  statements
regarding our intentions, beliefs, assumptions, projections, outlook, analyses or current expectations concerning, among other things, our
intellectual  property  position,  research  and  development  projects,  acquisitions,  results  of  operations,  cash  needs,  spending  of  the
remaining  net  proceeds  from  our  initial  public  offering,  capital  expenditures,  financial  condition,  liquidity,  prospects,  growth  and
strategies, regulatory approvals and clearances, the markets and industry in which we operate and the trends and competition that may
affect the markets, industry or us. In particular, under “Item 5. Operating and Financial Review and Prospects—D. Trend Information” of
this annual report and in the notes to our audited consolidated financial statements, we discuss, based on our current assessment of the
ongoing armed conflict in Ukraine, and other geopolitical tensions how our business, results of operations, and financial condition could
be impacted during the year 2024 and beyond.

By  their  nature,  forward-looking  statements  involve  risks  and  uncertainties  because  they  relate  to  events,  competitive  dynamics  and
industry  change,  and  depend  on  economic  circumstances  that  may  or  may  not  occur  in  the  future  or  may  occur  on  longer  or  shorter
timelines  than  anticipated.  Although  we  believe  that  we  have  a  reasonable  basis  for  each  forward-looking  statement  contained  in  this
annual report, we caution you that forward-looking statements are not guarantees of future performance and involve known and unknown
risks, uncertainties and other factors that are in some cases beyond our control. All of our forward-looking statements are subject to risks
and uncertainties that may cause our actual results to differ materially from our expectations.

Actual results could differ materially from our forward-looking statements due to a number of factors, including, without limitation, risks
related to:

● the  global  political,  economic,  and  macroeconomic  climate,  whether  within  our  industry  in  general,  or  among  specific
types  of  customers  or  within  particular  geographies,  including  but  not  limited  to,  the  impacts  related  to  labor  shortages,
supply  chain  disruptions,  actual  or  perceived  instability  in  the  global  banking  system,  the  results  of  local  and  national
elections, a potential recession, inflation, and rising interest rates;

● our ability to enhance and adapt our software, products and services to meet changing technology and customer needs;

● our international operations;

● our ability to comply with applicable governmental laws and regulations to which our products, services and operations are

subject; and

● other risk factors as set forth under “Item 3. Key Information – D. Risk Factors.”

Any forward-looking statements that we make in this annual report speak only as of the date of such statement, and we undertake no
obligation to update such statements to reflect events or circumstances after the date of this annual report or to reflect the occurrence of
unanticipated events. Comparisons of results for current and any prior periods are not intended to express any future trends or indications
of future performance, unless expressed as such, and should only be viewed as historical data. You should, however, review the factors
and risks we describe in the reports we will file from time to time with the U.S. Securities and Exchange Commission, or the SEC, after
the date of this annual report. See “Item 10. Additional Information – H. Documents on Display.”

You should also read carefully the factors described in “Item 3. Key Information – D. Risk Factors” and elsewhere in this annual report
to better understand the risks and uncertainties inherent in our business and underlying any forward-looking statements. As a result of
these factors, we cannot assure you that the forward-looking statements in this annual report will prove to be accurate. Furthermore, if
our forward-looking statements prove to be inaccurate, the inaccuracy may be material. In light of the significant uncertainties in these
forward-looking statements, you should not regard these statements as a representation or warranty by us or any other person that we will

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

and deploying a cloud-based platform to offer our software.

● We  may  not  be  able  to  successfully  adapt  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.

● Our failure to adequately address current and emerging sustainability risks, including environmental, social and governance

(ESG) matters, could have a material adverse effect on our business, financial condition and 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.

● 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.

4

Table of Contents

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.

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 (including the manufacturing of end use 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 use 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.

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.

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  licenses  or  maintenance  contracts  for  our  software,  including  from  customers  refusing  to
transition  from  perpetual  to  annual  licensing  models  for  our  software  or  disruptions  related  to  our  deployment  of  cloud-
based software solutions;

● 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;

7

Table of Contents

● changes in the regulatory environment, including changes in regulatory laws and regulations, and the interpretation thereof,

applicable to our software programs, products or services;

● 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 including those related to the armed
conflicts in Ukraine, Israel and the Middle East and the ongoing geopolitical tensions between the United States and China;
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 and 2023, including increasing the costs
of labor, energy, materials, and freight. We implemented price increases on many of our products and services in 2022 and 2023. 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 2024 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 for the production of end use parts does not
gain  more  mainstream  market  acceptance,  the  pace  by  which  additive  manufacturing  technology  gains  market  acceptance  does  not
accelerate or if the marketplace adopts additive manufacturing based on a technology other than the technologies that we currently use or
serve  (including  in  the  medical,  eyewear,  footwear  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;

8

Table of Contents

● 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;

● 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, and there is an increasing trend of consolidation among our existing suppliers, the increase in the prices charged by
our suppliers may have an adverse effect on our results of operations, as we may be unable to find a supplier who 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  and
deploying 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, through our CO-AM and Mimics Flow platforms
to offer our software products either by means of a SaaS or a cloud-based subscription model, there is no guarantee that 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,  the  SaaS  and  cloud-based  software  products  we  offer  reside  upon  and  are  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 adapt 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 use
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  our  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.

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, pandemics and epidemics;

● transportation delays;

● 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;

10

Table of Contents

● 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 conflicts in Ukraine, Israel and
the Middle East and the ongoing geopolitical tensions between the United States and China;

● 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, export controls, 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. The invasion of Ukraine by the Russian Federation on February 24, 2022, has impacted
our operations in Kyiv significantly.

Although our operations in Kyiv nearly ceased in the first quarter of 2022, we have since been able to gradually reorganize the internal
services provided from that region through a combination of measures, including Ukrainian collaborators who have fled to other regions
in  their  country  now  working  from  home,  support  provided  by  existing  (and  often  enlarged)  Materialise  teams  in  other  regions,  the
relocation of a number of Ukrainian collaborators outside of Ukraine, and, circumstances permitting, services provided from our Kyiv
office, which we have re-opened and accommodated to try to cope with the challenges resulting from the continuous military strikes on
key infrastructure in the country.

While  our  people  in  Ukraine  have  shown,  and  continue  to  show,  incredible  resilience  and  professionalism,  the  situation  in  Ukraine
remains unstable and uncertain and is expected to continue to have an impact on our operations, both financially and operationally. We
expect that, as long as the armed conflict continues (and possibly for a period thereafter), this impact will continue and may even worsen,
depending on the developments both geo-politically and in Ukraine. The ongoing additional mobilization for the Ukrainian army may
also impact our operations. Although we are presently determined to continue to flexibly support our operations in Kyiv and at present
do  not  see  any  reason  to  revise  that  strategy,  we  constantly  monitor  and  evaluate  the  situation.  Any  change  in  strategy  may  have  an
additional negative impact on our results of operations and financial condition.

We are unable to predict how the armed conflict in Ukraine will evolve and what the further political and economic repercussions will
be. As a result, we are unable to assess with certainty its future impact on our business and operations, results of operations, financial
condition,  cash  flows  and  liquidity.  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  2024,  this  discussion  should  be
considered as uncertain. While we expect to suffer adverse effects, the severity is currently impossible to assess.

Our international operations pose currency risks, which may adversely affect our results of operations and net income.

Our  results  of  operations  may  be  affected  by  volatility  in  currency  exchange  rates  and  our  ability  to  effectively  manage  our  currency
transaction risks. In general, we conduct our business, earn revenue and incur costs in the local currency of the countries in which we
operate. During the year ended December 31, 2023, 66% of our revenue was generated, and approximately 77% 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. 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.

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.

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.

As  noted  above,  any  security  compromise  that  causes  an  apparent  privacy  violation  could  also  result  in  legal  claims  or  proceedings;
liability under various laws and regulations that regulate the privacy, security, or breach of personal information; and related regulatory
penalties.  See  “—We  face  potential  liability  related  to  the  privacy  and  security  of  personal  information  we  collect.”  below  for  more
information. Moreover, the landscape of laws, regulations, and industry standards related to patient health and other private information,
data privacy and cybersecurity is evolving globally. We may be subject to increased compliance burdens by regulators and our customers
and the patients that we and our customers serve, as well as additional costs to oversee and monitor security risks. Many jurisdictions
have enacted laws mandating companies to inform individuals, shareholders, regulatory authorities, and others of security breaches. For
example,  the  SEC  recently  adopted  cybersecurity  risk  management  and  disclosure  rules,  which  require  the  disclosure  of  information
pertaining to cybersecurity incidents and cybersecurity risk management, strategy, and governance. In addition, certain of our customer
agreements may require us to promptly report security breaches involving their data on our systems or those of subcontractors processing
such  data  on  our  behalf.  This  mandatory  disclosure  can  be  costly,  harm  our  reputation,  erode  customer  trust,  and  require  significant
resources to mitigate issues stemming from actual or perceived security breaches.

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 as well as to host our SaaS and cloud-based software applications.
If these providers are unable to handle current or higher volumes of use, experience any interruption in operations or cease operations for
any reason or if we are unable to agree on satisfactory terms for a continued hosting relationship, we would be forced to enter into a
relationship with other service providers or assume these hosting responsibilities ourselves. Moreover, breaches of our customers’ data
caused  by  errors,  omissions  or  hostile  acts  of  third  parties  within  the  third  party  hosted  environment  are  beyond  our  control,  yet  we
would remain responsible for such data security incidents from a regulatory standpoint, in some instances. We may also be limited in our
remedies  against  our  third  party  hosting  providers  in  the  event  of  a  failure  of  service.  A  failure  or  limitation  of  service  or  available
capacity by our third party hosting providers could adversely affect our business and reputation.

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.

We develop and offer online software services through our SaaS and cloud-based software applications where we manage data we
receive from our customers, and a cybersecurity breach of these online services could harm our customers and our reputation, expose
us to liability, and adversely impact our business, financial condition and results of operations.

We are in an ongoing transition from distributing desktop software applications to developing and distributing online software services
through  our  SaaS  and  cloud-based  software  applications.  This  transition  comes  with  a  shift  in  cybersecurity  responsibilities  from  the
customer to us, since we manage data we receive from our customers and may be responsible to our customers for breaches of their data.
This shift in responsibilities requires us to implement appropriate internal changes and to invest in additional cybersecurity capabilities
(including training, tooling, and processes). However, cybersecurity incidents and malicious internet-based activity continue to increase
generally,  and  providers  of  cloud-based  services  have  frequently  been  targeted  by  such  attacks.  We  may  be  unable  to  anticipate  or
prevent techniques used to obtain unauthorized access or to sabotage systems because they change frequently and often are not detected
until  after  an  incident  has  occurred.  If  sensitive  customer  information  is  lost,  improperly  disclosed  or  threatened  to  be  disclosed,  our
reputation could be harmed, we could incur significant costs associated with remediation and the implementation of additional security
measures, we may incur significant liability and financial loss, and we may be subject to regulatory scrutiny, investigations, proceedings,
and penalties. In addition, certain of our customers are large and highly regulated, and if any of them were to conclude that our systems
and  procedures  are  insufficiently  rigorous,  they  could  terminate  their  relationships  with  us,  and  our  financial  condition,  results  of
operations and business could be adversely affected.

In  addition,  the  SaaS  and  cloud-based  software  applications  business  is  a  highly  dynamic  market  with  rapidly  evolving  regulatory
requirements,  and  we  need  to  continually  improve  our  cybersecurity  controls  to  ensure  continued  compliance.  We  are  investing  in
information security and privacy certifications to meet these evolving requirements. However, given the rapidly evolving nature of the
regulatory  landscape  (e.g.,  the  Cybersecurity  Maturity  Model  Certification  program  of  the  U.S.  Department  of  Defense,  the  EU-wide
NIS2 directive, the upcoming EU-wide Cyber Resilience Act), we may be unable to ensure timely compliance with these requirements,
which may adversely impact our business, financial condition and results of operations.

We may not be successful in our artificial intelligence and machine learnng initiatives, which could adversely affect our business,
reputation or financial results.

We  have  recently  begun  incorporating  generative  artificial  intelligence  (or  AI)  and  machine  learning  (or  ML)  into  our  programs  and
platforms,  particularly  in  the  Materialise  Medical  segment.  As  with  many  innovations,  AI  and  ML  present  risks,  challenges  and
unintended consequences that could impact our successful ability to incorporate the use of AI and ML in our business. For example, our
algorithms may be flawed and not achieve sufficient levels of accuracy or contain biased information. In addition, our competitors or
other third parties may incorporate AI and ML solutions into their platforms more successfully than us, and their AI and ML solutions
may achieve higher market acceptance than ours, which may result in us failing to recoup our investments in developing ML and AI-
powered offerings. We have made and expect to continue to make significant investments in our AI and ML technology. Our ability to
employ AI and ML, or any ability of our competitors to do so more successfully, may negatively impact our business, impair our ability
to compete effectively, result in reputational harm and have an adverse impact on our operating results.

Moreover, our use of AI and ML may give rise to litigation risk, including potential intellectual property or privacy liability. Because AI
is an emerging technology, there is not a mature body of case law construing the appropriateness of certain of its uses of data – whether
through the employment of large language models or other models leveraging data found on the internet – and the evolution of this law
may limit our ability to exploit artificial intelligence tools, or expose us to litigation. Further, AI and ML presents emerging ethical issues
and if our use of AI and ML algorithms draws controversy due to their perceived or actual impact on society, we may experience brand
or reputational harm, competitive harm or legal liability.

In addition, given the complex nature of AI and ML technology, we face an evolving regulatory landscape and significant competition
from  other  companies,  some  of  which  have  longer  operating  histories  and  significantly  greater  financial,  technical,  marketing,
distribution, professional services, or other resources than us. For example, the European Union’s Artifical Intelligence Act (or the AI
Act)  –  the  world’s  first  comprehensive  AI  law  –  is  anticipated  to  enter  into  force  in  the  spring  of  2024  and,  with  some  exceptions,
become  effective  24  months  thereafter.  This  legislation  imposes  significant  obligations  on  providers  and  deployers  of  high  risk  AI
systems, and encourages providers and deployers of AI systems to account for E.U. ethical principles in their development and use of
these systems. If we develop or use AI or ML systems that are governed by the AI Act, it may necessitate ensuring higher standards of
data  quality,  transparency,  and  human  oversight,  as  well  as  adhering  to  specific  and  potentially  burdensome  and  costly  ethical,
accountability, and administrative requirements. Any of the foregoing could adversely affect our business, reputation, or financial results.

If businesses do not continue to adopt our platform for any of the reasons discussed above or for other reasons not contemplated, our
sales would not grow as quickly as anticipated, or at all, and our business, operating results, and financial condition would be adversely
affected.

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.

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

● 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 could impact us include, but are not limited to the following:

● geopolitical instability resulting from, among other factors, the armed conflicts in Ukraine Israel and the Middle East and

the ongoing geopolitical tensions between the United States and China;

● the  risk  of  potential  recessions,  continued  rising  interest  rates,  inflation  and  labor  shortages  in  Europe  and  the  United

States;

● actual or perceived instability in the global banking system;

● disruptions caused by global health crises, pandemics and epidemics and related responses thereto in certain economies and

markets; 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, including as a result of political elections, could also result in changes to legislation or
reformation  of  government  policies,  rules  and  regulations  that  adversely  impact  our  business,  such  as  changes  in  policies,  rules  and
regulations related to taxation or 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

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. In addition, in our Materialise
Software segment, we collect, transmit, process and store large amounts of proprietary or other sensitive data from our customers through
our SaaS and cloud-based software applications, some of which are highly regulated.

In  the  United  States,  we  are  subject  to  the  Health  Insurance  Portability  and  Accountability  Act,  or  HIPAA,  the  Health  Information
Technology for Economic and Clinical Health Act of 2009, regulations issued pursuant to these statutes, state privacy and security laws
and regulations. These statutes, regulations and contractual obligations impose numerous requirements regarding the use and disclosure
of personal health information with which we must comply. In addition, we are subject to data privacy and cybersecurity laws such as the
California Consumer Privacy Act, or CCPA, as amended and expanded by the California Privacy Rights Act, or CPRA. The CCPA, as
amended  by  the  CPRA,  requires,  among  other  things,  covered  companies,  including  us,  to  provide  new  disclosures  to  California
consumers and afford such consumers the ability to opt out of certain sales of personal information. We are undertaking appropriate steps
to modify our data processing practices and policies to comply with data privacy and cybersecurity laws and expect to incur substantial
costs and expenses in an effort to comply with such laws, including in connection with our development and deployment of SaaS and
cloud-based software solutions.

In the European Union, 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. On July 10, 2023, the European Commission adopted its
adequacy decision for the E.U.-U.S. Data Privacy Framework. The decision concludes that the United States ensures an adequate level of
protection – comparable to that of the European Union – for personal data transferred from the European Union to U.S. companies under
the  new  framework.  On  the  basis  of  the  new  adequacy  decision,  personal  data  can  flow  safely  from  the  European  Union  to  U.S.
companies participating in the E.U.-U.S. Data Privacy Framework, without having to put in place additional data protection safeguards.
The  adequacy  decision  followed  the  adoption  of  Executive  Order  on  “Enhancing  Safeguards  for  United  States  Signals  Intelligence
Activities”  by  U.S.  President  Biden  on  October  7,  2022,  and  a  regulation  issued  by  the  U.S.  Attorney  General.  These  measures
introduced new binding safeguards to address the points raised by Court of Justice of the European Union in its Schrems II decision of
July  2020,  ensuring  that  data  can  be  accessed  by  U.S.  intelligence  agencies  only  to  the  extent  necessary  and  proportionate  and
establishing an independent and impartial redress mechanism to handle and resolve complaints from Europeans concerning the collection
of their data for national security purposes.

The safeguards that have been put in place by the U.S. government in the area of national security (including the redress mechanism)
apply  to  all  data  transfers  under  the  GDPR  to  companies  in  the  United  States,  regardless  of  the  transfer  mechanisms  used.  These
safeguards therefore also facilitate the use of other tools, such as standard contractual clauses.

We are investigating and are undertaking appropriate steps to mitigate the risks associated with these evolving data privacy laws and data
transfer requirements.

In 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.

Our failure to adequately address current and emerging sustainability risks, including environmental, social and governance (ESG)
matters, could have a material adverse effect on our business, financial condition and results of operations.

Our  ability  to  ensure  a  resilient  business  that  delivers  long-term  sustainable  growth,  is  reliant  on  our  ability  to  identify  current  and
emerging sustainability risks and legislative requirements that could adversely impact our business and ensure appropriate strategies are
in place to manage such risks and requirements. Some of the key risks and requirements include:

● Growing expectations of how businesses respond to and address sustainability issues from customers, non-governmental
organizations,  ESG-focused  investors  and  other  stakeholders.  The  failure  to  meet  these  expectations  can  have  adverse
consequences, such as: active product delisting, negative non-governmental organization campaigns, loss of market share,
omission from sustainability indices and adverse public perception or publicity;

● Increased  mandatory  sustainability  due-diligence  and  non-financial  reporting  and  disclosure  obligations,  requiring
businesses  to  take  appropriate  action  or  face  regulatory  penalties.  This  includes  the  SEC’s  recently  adopted  climate
disclosure  rules,  as  well  as  laws  and  regulations  in  the  countries  where  we  operate,  such  as  the  E.U.  Corporate
Sustainability Due Diligence Directive, the E.U. Corporate Sustainability Reporting Directive, the German Supply Chain
Due Diligence Act, California’s Voluntary Carbon Market Disclosures Act, the Task Force on Climate Related Financial
Disclosure (TCFD) and the proposed Task Force on Nature Related Financial Disclosures (TNFD).

● Physical risks of climate change, such as increased frequency of extreme weather and natural disasters, causing damage to

physical assets within our operations and our supply chain.

Any of the above risks, together with any others which relate to our inability to address increased and emerging sustainability risks, could
have a material adverse effect on our business, financial condition and results of operations. Further, our efforts to address current and
emerging sustainability requirements could result in increased costs and divert management’s attention and resources from our business.

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;

● the suspension or revocation of the authority necessary for the production or sale of a product;

Table of Contents

● 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.

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.

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.  While  we  have  taken  the  first  steps  to  comply  with  the  Medical  Device
Regulation’s requirements and obtained CE Certificates of Conformity, any future failure by us to keep our quality system and regulatory
documentation in accordance with the Medical Device Regulation’s requirements could delay our further transition to compliance and
delay  or  prevent  us  from  obtaining  new  CE  Certificates  of  Conformity.  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.

23

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.

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.  A  FSCA  is  an  action  taken  by  a
manufacturer to reduce a risk of death or serious deterioration in the state of health associated with the use of a medical device that is
already placed on the market. A FSCA may include the recall, modification, exchange, destruction or retrofitting of the device. FSCAs
must be communicated by the manufacturer or its legal representative to its customers and/or to the end users of the device through Field
Safety Notices.

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;

25

Table of Contents

● 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;

● 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.

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.

We have been and may in the future be subject or party, directly or indirectly, to claims, negotiations or complex, protracted litigation,
arbitration or post-grant review proceedings in connection with the enforcement of our intellectual property and patent rights.

27

Table of Contents

While we strive to avoid infringing the intellectual-property rights of third parties, we cannot provide any assurances that we will be able
to  avoid  any  claims,  directed  against  us  directly  or  against  our  collaboration  partners  or  our  other  customers,  that  our  products  and
technology,  including  the  technology  that  we  license  from  others,  infringe  the  intellectual-property  rights  of  third  parties.  Patent
applications  in  the  United  States  and  most  other  countries  are  confidential  for  a  period  of  time  until  they  are  published,  and  the
publication of discoveries in scientific or patent literature typically lags behind the actual discoveries by several months or more. As a
result, the nature of claims contained in unpublished patent filings around the world is unknown to us, and 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,  such  as  the  European  Patent  Convention,  or  to  predict  the  final  scope  of
protection that may result from pending patent applications. Moreover, the patent landscape in the different fields in which we operate is
heavily  occupied  and  freedom  to  operate  examinations  are  costly  and  time-consuming.  We  have  not  obtained  extensive  freedom  to
operate reports in the past for each and all of our products and services, nor do we intend to install on a general basis freedom to operate
examinations for our future products and services. In addition, we may be subject to intellectual property infringement claims from non-
practicing  entities,  individuals,  vendors  and  other  companies,  including  those  that  are  in  the  business  of  asserting  patents,  but  are  not
commercializing  products  or  services  in  the  different  fields  in  which  we  operate,  or  our  collaboration  partners  or  our  other  customers
may seek to invoke indemnification obligations to involve us in such intellectual-property infringement claims. Furthermore, although
we maintain certain procedures to help to ensure that the items we 3D print on behalf of customers do not infringe upon the intellectual-
property rights of others, we cannot be certain that our procedures will be effective in preventing any such infringement.

Intellectual-property disputes, litigation and arbitration, regardless of the merit or resolution, could cause us to incur significant costs in
enforcing, or responding to, defending and resolving such claims. In addition, such claims 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.

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  payment  fee  or  by  other  means  of
redress in accordance with the applicable rules, there are situations in which noncompliance can result in definitive lapse of a 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  to  defend  against  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.

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 jointly by us and the relevant partner may be
subject to joint ownership by us and the partner and our commercial use of such intellectual-property may be restricted, or may require
written consent from, or a separate agreement with, the partner. In other cases, we may not have any rights to use intellectual property
solely developed and owned by the partner. If we cannot obtain commercial use rights for such jointly-owned intellectual property or
partner-owned  intellectual  property,  our  future  product  development  and  commercialization  plans  may  be  adversely  affected.  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, actual or perceived instability in the global banking system,
the  results  of  local  and  national  elections,  international  currency  fluctuations,  epidemics  and  pandemics,  corruption,
political instability and acts of war, such as the armed conflicts in Ukraine, Israel and the Middle East, or terrorism;

● significant  volatility  in  the  market  price  and  trading  volume  of  securities  of  companies  in  our  sector,  which  is  not

necessarily related to the operating performance of these companies;

29

Table of Contents

● 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;

● 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 26, 2024. These shareholders have significant influence over the election
of members of our board of directors and the outcome of corporate actions requiring shareholder approval, including dividend policy,
mergers, share capital increases, amendments of our restated articles of association and other extraordinary transactions. For example,
these  shareholders  may  be  able  to  influence  the  outcome  of  elections  of  members  of  our  board  of  directors,  amendments  of  our
organizational  documents,  or  approval  of  any  merger,  sale  of  assets,  or  other  major  corporate  transactions.  In  addition,  our  restated
articles  of  association  provide  that,  as  long  as  Wilfried  Vancraen,  our  founder  and  a  member  of  our  board  of  directors,  and  Hilde
Ingelaere, a member of our board of directors, who is also Mr. Vancraen’s spouse, and their three children, Linde, Sander (who is also a
member of our board of directors) and Jeroen Vancraen, or collectively the Family Shareholders, control, directly or indirectly, in the
aggregate  at  least  20%  of  the  voting  rights  attached  to  our  ordinary  shares,  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, 2023, there were outstanding granted warrants to subscribe for an aggregate
of 423,452 ordinary shares at a weighted average exercise price of €5.39 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.

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.

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, 2024. 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,  2023,  3%  of  our  assets  were
located  in  the  United  States.  The  regulatory  and  compliance  costs  to  us  under  U.S.  securities  laws  as  a  U.S.  domestic  issuer  may  be
significantly greater than the costs we incur as a foreign private issuer. If we are not a foreign private issuer, we will be required to file
periodic reports and registration statements on U.S. domestic issuer forms with the SEC, which are more detailed and extensive in certain
respects than the forms available to a foreign private issuer. We would be required under current SEC rules to prepare our consolidated
financial statements in accordance with U.S. GAAP and modify certain of our policies to comply with corporate governance practices
associated with U.S. domestic issuers. Such conversion and modifications would involve significant additional costs. In addition, we may
lose our ability to rely upon exemptions from certain corporate governance requirements on U.S. stock exchanges that are available to
foreign  private  issuers  such  as  the  ones  described  above  and  exemptions  from  procedural  requirements  related  to  the  solicitation  of
proxies.

If we fail to maintain an effective system of internal control over financial reporting in the future, we may not be able to accurately
report our financial condition, results of operations or cash flows, which may adversely affect investor confidence in us.

The Sarbanes-Oxley Act requires, among other things, that we maintain effective internal control over financial reporting and disclosure
controls  and  procedures.  In  particular,  we  are  required,  under  Section  404  of  the  Sarbanes-Oxley  Act,  to  perform  system  and  process
evaluations  and  testing  of  our  internal  controls  over  financial  reporting  to  allow  management  and  our  independent  registered  public
accounting firm to report on the effectiveness of our internal control over financial reporting. This assessment must include disclosure of
any  material  weaknesses  in  our  internal  control  over  financial  reporting  identified  by  our  management  or  our  independent  registered
public  accounting  firm.  A  material  weakness  is  a  control  deficiency,  or  combination  of  control  deficiencies,  in  internal  control  over
financial  reporting  that  results  in  more  than  a  reasonable  possibility  that  a  material  misstatement  of  annual  or  interim  consolidated
financial statements will not be prevented or detected on a timely basis. Section 404 of the Sarbanes-Oxley Act also generally requires an
attestation from our independent registered public accounting firm on the effectiveness of our internal control over financial reporting.
Our independent registered public accounting firm may issue a report that is adverse in the event it is not satisfied with the level at which
our  controls  are  documented,  designed  or  operating.  Our  remediation  efforts  may  not  enable  us  to  avoid  a  material  weakness  in  the
future.

32

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.

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.

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.

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.

million and an Adjusted EBITDA of € 31.4 million. For a description of Adjusted EBITDA and a reconciliation of our net profit to our
Adjusted EBITDA, see “Item 5. Operating and Financial Review and Prospects—A. Operating Results—Other Financial Information.”

Our Core Competencies

Our  established  and  proven  business  model  integrates  our  three  research-based  core  competencies:  (i)  software  development,  (ii)  3D
printing, and (iii) engineering for 3D printing, which act as complementary incubators for our new products and function as integrated
support centers for our existing products. The interaction and synergies among our software development, 3D printing and engineering
teams  position  us  well  to  continuously  develop  and  support  innovative  applications  of  3D  printing  that  often  integrate  all  three  core
competencies.

Software Development (Software). Our expertise in developing 3D printing software originated from our efforts to enable 3D printing
applications  and  to  continually  improve  processes  within  our  own  additive  manufacturing  operations.  As  a  result  of  our  continued
deployment over the course of 30 years of human, intellectual and economic capital to software development, a number of our products,
including Magics and Mimics, have evolved into industry-leading flagship products. We have an established quality management system
for  the  development  of  our  software  products  that  is  ISO  9001:2015  certified.  We  are  also  ISO  13485:2016  certified  for  our  medical
applications  and  our  medical  applications  comply  with  the  regulatory  requirements  of  several  jurisdictions,  including  Europe  and  the
United  States.  Additionally,  we  are  ISO27001  certified  for  the  secure  operational  management  of  the  production  environment  of  our
cloud-based software for medical case management and medical image processing.

3D Printing (Hardware). As a pioneer in the additive manufacturing industry, we have an extensive history of 3D printing millions of
parts utilizing a broad array of technologies, often in highly regulated environments, for thousands of commercial, industrial and medical
customers.  We  operate  some  of  the  most  sophisticated  printing  machines  currently  available  on  the  market,  as  well  as  our  own
proprietary stereolithography-based technology, Mammoth, to provide a very broad range of technologies, sizes, materials and finishing
degrees and to address the needs of customers across a large number of potential markets. Production is organized in multiple production
lines that are dedicated to the Medical and the Industrial Production segments that we serve. Our 3D printing group operates in an ISO
13485:2016-certified system for the production of medical devices, in an EN9100:2018 as well as EASA Part 21G POA certified system
for  the  production  of  plastic  aerospace  parts,  and  in  an  ISO  9001:2015-certified  quality  management  system  for  all  other  markets.
Further, our 3D printing group has its own maintenance and research team that utilizes an in-house laboratory facility where products can
be  tested.  The  wide  variety  of  products  that  are  processed  by  our  multiple  production  lines  are  logistically  streamlined  through  our
proprietary database systems that manage the entire process from order intake to 3D printing to final shipment.

37

Table of Contents

Engineering (Mindware). Our engineering expertise is integral to our entire business, as it enhances our software development and 3D
printing expertise. Our engineers work in teams that support customers in different market segments. These teams work directly with our
customers to identify new, and customize and refine existing, 3D printing applications and to increase productivity, efficiency and ease of
use across all aspects of the solutions we provide. Our engineering teams have particular expertise in industrial and medical applications,
including patient-specific surgical guides, models and implants with the applicable market clearances. Our teams are highly specialized,
especially  in  the  medical  field,  and  include  quality  controllers,  development  researchers  for  new  hardware  concepts  and  trainers  who
bring new engineers to the required level of expertise. Our engineers operate within the framework of the aforementioned ISO 9001:2015
certified quality management system. Our engineering teams make extensive use of our proprietary software tools and have direct access
to our 3D printing center where developments can be tested in an actual production environment.

Our Market Segments

We  offer  our  products  and  services  through  a  market  oriented  organization  that  is  active  across  three  principal  market  segments:
(i) Materialise Software, (ii) Materialise Medical, and (iii) Materialise Manufacturing. We believe that our customers benefit significantly
from  the  synergistic  interplay  between  our  core  competencies  and  the  three  market  segments  on  which  we  focus  and  which  provide
regular end-user feedback to the product development and support teams within our core competencies.

Our Materialise Software Segment

In our Materialise Software segment, we offer proprietary software worldwide through programs and platforms that enable companies to
set up efficient, reliable and sustainable 3D printing production. Our software supports 3D printing service bureaus both large and small
that are producing a variety of parts for their customers and addresses the needs of large corporations producing at volume, either through
significant serial manufacturing or mass customization. In all of these environments, we believe our software enables both operational
excellence and flexibility. We work directly with many 3D printing machine manufacturers to enable and enhance the functionality of 3D
printers and of 3D printing operations. We have developed software that interfaces between almost all types of industrial 3D printers, and
various software applications and capturing technologies, including CAD/CAM packages and 3D scanners, by enabling data preparation
and process planning and execution. Our programs interface with machines manufactured by leading original equipment manufacturers,
or OEMs, such EOS GmbH, HP Inc., DesktopMetal, Inc., Renishaw PLC, SLM Solutions Group AG, Stratasys Ltd., Trumpf GmbH &
Co. KG, Uniontech Corporation, GE Additive and Voxeljet AG. In addition, we have entered into partnership agreements with leading
CAD,  CAM  and  product  lifecycle  management,  or  PLM,  companies  such  as  Siemens,  HCL  Technologies  Ltd.,  and  PTC,  for  the
integration  of  our  additive  manufacturing  technology  into  Siemens’  NX  software,  HCL’s  CAMworks,  and  PTC’s  Creo  software.  This
enables the streamlining of the design to manufacturing process for products being produced by additive manufacturing. We have also
established connectivity between our software and the software of other providers in the broader 3D printing ecosystem like AM Flow,
PostProcess, Castor, AMT, Dyemansion, Additive Marking, Twikit and Trinkle. We offer software that enables our customers to more
efficiently  organize  the  entire  workflow  of  a  3D  printing  operation  with  multiple  3D  printing  machines,  many  operators  and  complex
data flow and logistical requirements. We believe that the capabilities of our software products and their unique compatibility with many
3D  printing  systems  continue  to  set  standards  in  the  professional  3D  printing  software  market.  Customers  operating  machines  from
multiple  OEMs  and  customers  running  large  3D  printing  operations  are  among  those  who  can  benefit  the  most  from  our  software
packages and we believe that in many cases those customers demand compatibility with our software from the systems of OEMs.

As  of  December  31,  2023,  our  Materialise  Software  segment  had  a  team  of  approximately  293  FTEs  and  fully  dedicated  consultants,
with approximately 31% based at our headquarters in Belgium and the remaining employees distributed throughout our local field offices
in China, Colombia, Germany, Japan, Malaysia, Ukraine, the United Kingdom and the United States.

Business Model. We generate revenue in our Materialise Software segment from our software licenses, maintenance contracts, hardware
controller  sales  for  our  Materialise  Controllers  and  custom  software  development  services.  Additionally,  we  offer  consultancy  and
training services. We license our software products to our customers on either a time-based or perpetual basis, in which case we offer
annual  maintenance  contracts  that  provide  for  software  updates  and  support.  In  addition,  we  also  provide  a  number  of  cloud-based
solutions. Making use of, among others, our CO-AM platform, we are significantly accelerating the migration of our software solutions
to  the  cloud,  which  we  intend  to  offer  along  with  our  license-based  solutions.  We  charge  our  custom  software  development  services
either on a time and material or on a fixed-cost basis. For the years ended December 31, 2023, 2022 and 2021, our Materialise Software
segment  generated  revenue  of  €  44.4  million,  €43.7  million  and  €42.9  million,  respectively,  representing  17.4%  18.8%  and  20.9%,
respectively, of our total revenue.

38

Table of Contents

Software. We have a diversified portfolio comprised of software applications addressing different 3D printing market opportunities. Our
decades  of  experience  in  the  additive  manufacturing  industry  are  reflected  in  the  sophisticated  3D  printing  software  and  business
management tools we provide for our customers. We believe that each of our software applications is, or has the potential of becoming,
one  of  the  leading  technologies  in  its  domain.  We  believe  that  our  neutral  platform  approach  positions  our  software  to  drive  greater
innovation and choice across the 3D printer software ecosystem, and provides 3D printer users with more powerful and flexible printing
capabilities.

In particular, we offer the following software applications:

● Magics. Magics enables customers to import a wide variety of CAD formats and to the industry standard file formats 3MF
and STL, as well as to the enriched BREP and MeshREP data format proprietary to us, ready for additive manufacturing.
Magics’ applications include repairing and optimizing 3D models; analyzing parts; making process-related design changes
on customers’ input files; designing support structures; documenting customer projects; nesting multiple parts in a single
print run; and process planning.

Our  Magics  product  suite  is  enhanced  with  modules  that  further  expand  functionality  and  utility  for  our  customers.  For
instance, the Magics Import Module plays an important role in efficiently moving CAD designs through to manufactured
products by importing nearly all standard CAD formats into Magics. The Magics Structures Module was designed to help
customers  to  reduce  weight  and  material  usage  in  their  designs.  We  also  have  developed  logistical  modules  such  as  the
Magics  SG  Module,  which  offers  tools  for  support  structure  design  during  the  3D  printing  process,  and  the  Magics
Sintermodule, which offers solutions for automated part nesting, protecting small and fragile parts and locating them after
building. The Magics Simulation Module enables our users to simulate the build process virtually and optimizes the build
preparation based on the results of such simulation, thus reducing build failures and improving the results.

In addition to offering state-of-the-art data preparation functionality to our users, our Magics product suite also focuses on
automation  and  other  productivity  improvements  and  brings  interconnectivity  to  machines  and  enterprise  software
platforms.

Specific versions of the Magics application were also brought to the market by us, including Magics Essentials (an entry-
level  package  offering  premium  data  preparation  functionality),  Magics  Print  (combining  the  most  important  build
preparation  tools  and  straightforward  build  file  generation  technology)  and  MiniMagics/MiniMagicsPro  (providing
viewing,  communication  and  quoting  solutions  for  our  customers  working  in  data  preparation,  or  in  quoting  and  quality
control teams). Users of Magics Essentials and Magics Print can upgrade to our expert Materialise Magics product suite if
they want the full data and build preparation functionality at their disposal in one package.

● CO-AM. CO-AM is an additive workflow and digital manufacturing software platform 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  and  costing,  production  planning,  production  scheduling,
postproduction management, machine connectivity, quality management and manufacturing analytics.

● Streamics. Streamics is our legacy 3D Print planning system that we consider as the predecessor of the CO-AM platform.
We  are  gradually  migrating  Streamics  functionality  to  our  CO-AM  platform.  Once  the  Streamics  functionality  is  fully
integrated in CO-AM, a transition plan will be set up to migrate existing Streamics customers to the Link3D platform over
the coming years. In the meantime, we will continue to maintain and support Streamics and its customers.

● 3-matic. 3-matic is a versatile application that permits, among other things, design modification, design simplification, 3D
texturing, re-meshing and forward engineering directly to standard additive manufacturing mesh files. Using Materialise
consultancy services, targeted design automation solutions can be created for specific workflows.

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  and  the  availability  of  a  BP-SDK  (Software
Development Kit) also allows for custom fit-for-purpose build pipelines to be scripted, enabling companies and 3D printer
machine vendors alike to adapt and optimize the behavior and output of the build processor. This BP-SDK is available for
customers to build their own build pipelines whilst having the possibility to integrate their proprietary IP in these pipelines.
We believe this is very valuable in the context of volume production.

● e-Stage.  e-Stage  is  a  software  solution  that  increases  additive  manufacturing  productivity  by  automating  support
generation,  optimizing  the  build  process,  and  reducing  the  time  our  customers  spend  on  finishing  work  such  as  build
support removal and sanding. e-Stage is designed to allow our customers to use less material, to be able to 3D nest and to
minimize failed builds. e-Stage for plastic has been commercially available since September 2007, and in the fall of 2017,
we released e-Stage for metal.

● 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 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 in creating specific end-to-end workflows, which can be executed automatically and autonomously, or can be
called from other software solutions like Magics through the Workflow Automation plugin function. 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.

● Layer  Analysis.  Layer  Analysis  is  a  Machine  Learning  (ML)  based  tool  that  interprets  images  taken  during  the  print  of
parts and looks for anomalies during the printing process. The tool combines the ML identified anomaly volumes with the
to-be 3D files, allowing users to detect immediately after finishing a print if certain printed parts may show defects. In this
way,  unnecessary  and  expensive  post-processing  and  (non-destructive)  quality  control  can  be  avoided  while  it  helps
customers as well in defining allowable defects that do not affect the eventual part quality.

Sales and Marketing. We market and distribute our software directly through our sales force as well as through our own website and
third party distributors. Our Belgian team oversees our global marketing strategy and sales processes. Our local field office employees
manage  sales  for  particular  markets  and  provide  pre-  and  post-sales  technical  support  to  our  customers.  We  also  utilize  a  growing
network of distributors and resellers to bring our solutions to specific regions or market segments. In addition, machine manufacturers
and their local dealers often distribute our software products together with their 3D printers, with our software enhancing the printers’
value proposition and broadening the suite of applications available to the machines.

Customers.  The  customers  for  our  Materialise  Software  segment  include  3D  printing  machine  manufacturers  as  well  as  production
companies  and  contract  manufacturers  in  a  variety  of  industries,  such  as  the  automotive,  aerospace,  consumer  goods  and  hearing  aid
industries, and external 3D printing service bureaus. Our Materialise Software segment customer base is spread across Asia, Europe and
the Americas.

40

Table of Contents

Competition.  In  our  Materialise  Software  segment,  we  face  indirect  competition  from  the  software  developed  by  3D  printing  OEMs,
which are often more “closed ecosystem”-oriented (i.e., only focused on their own machines), and from companies that offer software
that addresses one or more specific functional areas covered by our software solutions, such as providers of traditional CAD solutions.
We compete directly with other providers of additive manufacturing management and machine control software, including open source
software providers.

Growth Opportunities. We believe that 3D printing will be increasingly used for the manufacturing of complex or customized end use
parts, and expect that the number of 3D printer manufacturers will increase accordingly, with certain new players initially focusing more
on  the  hardware  than  on  the  software  component  of  their  3D  printers.  Hence,  we  anticipate  that  the  demand  for  highly  performing
industrial 3D printing software platforms will grow accordingly. The new products that we have developed and are developing, including
the CO-AM platform, Process Tuner, Workflow Automation and fit-for-purpose build processors specifically address what we believe
will be the needs of this growing end use part manufacturing market.

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 use
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.

● Materialise  3-matic.  Materialise  3-matic  focuses  on  anatomical  design  and  is  able  to  combine  CAD  tools  with  pre-
processing  capabilities  directly  on  the  anatomical  data  coming  from  Materialise  Mimics.  It  enables  our  customers  to
conduct thorough 3D measurements and analysis, design a patient-specific implant, a surgical guide, or a benchtop model,
and to prepare the anatomical data and/or resulting implants for simulation.

● Materialise  OrthoView.  Materialise  OrthoView  is  a  2D  digital  pre-operative  planning  and  templating  solution  for
orthopedic surgeons. The software imports a digital X-ray image from a Picture Archiving and Communication System, or
PACS, and positions the templates of suitable prostheses on the X-ray image at the correct scale. Materialise OrthoView
currently serves more than 15,000 orthopedic surgeons in 60 countries globally, focusing primarily on joint replacements.
We acquired OrthoView Holdings Limited in October 2014, and have included the OrthoView solution in our portfolio of
pre-operative planning solutions.

● Materialise  Mimics  inPrint.  With  Materialise  Mimics  inPrint,  clinicians  can  easily  create  files  for  3D  printing  and  use

anatomically accurate models to help simulate or evaluate options for patient-specific surgical treatment.

● Materialise ProPlan CMF. Materialise ProPlan CMF is a software package developed for oral, maxillofacial, nose, throat
and plastic surgeons. The software allows surgeons to pre-operatively plan their surgeries in 3D based on (CB)CT or MRI
images using a set of tools to analyze, measure and reconstruct the patient’s anatomy. With the software the surgeon can
also plan the movements (translations and rotations) of the mandible or maxilla and preplan the reconstruction of defects.

● Materialise Mimics Enlight.  Materialise  Mimics  Enlight  is  a  workflow-based  planning  software  that  enables  companies,
clinicians  and  hospitals  to  scale  3D  planning  for  procedures.  Mimics  Enlight  is  based  on  the  strengths  of  Materialise’s
Mimics Innovation Suite and can be applied in various clinical fields such as structural heart or lung surgery.

● Materialise  Surgicase.  Materialise  Surgicase  is  an  online  case  management  platform  that  enables  medical  device

companies and hospitals to manage ordering and processing of personalized services and devices.

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.

In  many  cases  surgeons  use  personalized  surgical  guides  or  implants  to  translate  the  surgical  plan  into  the  operating  room.  Our  3D
printed surgical guides include joint replacement guides for knee, shoulder and hip replacement surgeries, osteotomy guides and CMF
guides,  and  our  3D  printed  implants  include  hip-revision  implants,  shoulder  and  CMF  implants.  The  surgical  guides  and  implants  we
print for U.S. based patients are FDA-cleared, and to the extent required by law, our medical devices for EEA-based patients bear the
appropriate CE labels.

We address large surgical markets in orthopedics and CMF through collaboration agreements with leading medical device companies,
including  DePuy  Synthes,  Zimmer  Biomet,  Enovis,  and  Smith  &  Nephew.  Pursuant  to  these  agreements,  we  print  joint  replacement
and/or  CMF  guides  that  our  collaboration  partners  distribute  under  their  own  brands,  together  with  their  own  implants,  in  the  United
States, Canada, South Africa, Latin America, Europe, China, Japan and Australia. We leverage our collaboration partners’ distribution
capabilities  to  extend  our  reach  into  these  large  markets,  and  our  collaboration  partners  utilize  our  3D  printing-related  expertise  to
provide surgical planning and customized devices to surgeons.

42

Table of Contents

We  also  address  certain  high  value-added,  specialty  applications  by  providing  the  full  solution  ourselves,  including  the  delivery  of
implants and guides directly to the hospital or surgeon. Such applications include customized CMF implants and guides, hip revision and
shoulder  implants  in  a  patented  porous  matrix  configuration  and  osteotomy  guides.  Through  Engimplan,  we  distribute  implants  and
instruments in Brazil, offering both traditional and 3D printed CMF products as well as a broader portfolio that includes product lines for
trauma and sport medicine.

We also work with customers to print anatomical models that may be used for a wide range of applications such as sizing of medical
devices, clinical trials, training, patient communications and marketing.

Sales and Marketing. We distribute our medical software through our direct sales force, our website and PACS partners (some of which
partners also include our OrthoView solutions in their product offering to hospitals) and sell our medical devices through our agreements
with collaboration partners such as Zimmer Biomet and Depuy Synthes. In specialty markets, we market and distribute our 3D printed
medical  devices  and  other  clinical  services  through  our  experienced  engineers  who  develop  a  close  collaboration  with  key  opinion
leaders in each of these market segments.

All our activities in our Materialise Medical segment are coordinated and supervised from our headquarters in Belgium, which supervises
product management and sales of our medical devices and software products.

Customers.  The  customers  for  our  Materialise  Medical  segment  mainly  include  medical  device  companies,  hospitals,  universities,
research institutes and industrial companies. We have one individual customer that represents sales larger than 10% of our total revenue
in 2023 (2022: 1; 2021: 1) from the Materialise Medical segment.

Collaboration  Partners.  We  collaborate  with  leading  medical  device  companies  and  academic  institutions  for  the  development  and
distribution of our surgical planning software, services, and products, such as Zimmer Biomet and DePuy Synthes, as well as Enovis,
Integra, Lima, Mathys, Medtronic, Abbott and Corin. Pursuant to these arrangements, we develop and license software and sell surgical
planning, guides and implants, including for use in the fields of knee and shoulder replacement, CMF and thoracic procedures that our
collaboration partners may then distribute under their own brands, together with their own implants, mainly in the United States, Europe,
Japan and Australia. In addition, we grant licenses to collaboration partners to use, market and distribute such software or surgical guides
and implants. Some of the licenses we have granted to our products and software provide for exclusive rights, including with respect to a
particular field of medicine or to the software or product developed during the collaboration, and certain collaboration partners may have
rights of first refusal with respect to related products or collaborations. The compensation structures under these arrangements vary and
may include an upfront fee, royalties, milestone payments linked to certain targets, and fees for the service, maintenance and training we
provide in connection with our software and products.

Competition. In  our  Materialise  Medical  segment,  we  compete  with  a  number  of  companies  that  provide  image  based  software,  3D
printed surgical models or medical devices, such as 3DSystems, Stratasys, Simpleware and Pie Medical as well as with medical device
companies that develop and commercialize 3D printed medical devices and related software services.

Growth  Opportunities.  The  Materialise  Medical  segment  is  the  market  where  we  believe  we  can  most  directly  realize  our  mission
statement and contribute to a healthier world. We believe that personalized surgical approaches, because they offer the potential of higher
predictability  and  accuracy,  lead  to  improved  patient  outcomes,  fewer  complications  and  increased  long-term  survival  rates.
Personalization  also  drives  operational  efficiencies  by  replacing  a  broad  range  of  instrumentation  with  tailored  versions.  This  makes
surgery more efficient, but also lowers the cost of operational steps like sterilization. Personalized surgical approaches have benefits not
only in complex interventions and we believe that personalized solutions will therefore see an increased adoption in the future.

As  a  result,  we  are  currently  investing  significantly  in  the  development  of  new  product  offerings  and  the  optimization  of  existing
offerings  in  terms  of  cost  and  lead  times,  as  well  as  in  the  expansion  of  our  distribution  channel  in  the  various  sub-segments  of  our
Materialise Medical segment and in new territories.

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. In addition, we have identified, and provide 3D printing services to certain specialty growth markets in
both the industrial and consumer marketplaces.

Many of the parts we print require functionality that cannot be delivered using other production processes. We believe that our industrial
customers value the high quality, accuracy, complexity, durability, functionality and diversity in terms of size, scale and materials of the
3D  printing  services  that  we  can  offer.  We  deliver  products  to  highly  regulated  industries,  such  as  the  aerospace,  medtech,  machine
manufacturing, quality control equipment and consumer goods industries, where our applications, technology and hardware capabilities
enable us to adhere to high quality standards in a certified production environment.

As  of  December  31,  2023,  our  Materialise  Manufacturing  segment  consisted  of  784  FTEs  and  fully  dedicated  consultants,  with  31%

local field offices in Austria, the Czech Republic, France, Germany, India, Italy, Poland, Spain, Ukraine, the United States and the United
Kingdom.

Business Model. We generate a majority of our revenue in our Materialise Manufacturing segment through the sale of parts that we print
for our customers. We generate a smaller portion of our revenue by the sale of scanners (e.g., foot scan plates for Materialise Motion) and
software solutions in our eyewear and footwear business and consulting services that mainly help our customers to find applications for
3D printing.

For the years ended December 31, 2023, 2022, and 2021, our Materialise Manufacturing segment generated revenue of € 110.3 million, €
103.5 million, and € 89.2 million, respectively, representing 43.1%, 44.6%, and 43.4% respectively, of our total revenue.

Business-to-Business Services. We offer the following services in our Materialise Manufacturing segment:

Additive  Manufacturing  Solutions.  We  provide  design  and  engineering  services,  rapid  prototyping  and  additive  manufacturing  of
production  parts  to  customers  serving  the  automotive,  consumer  goods  industrial  goods,  semiconductor,  art  and  architecture  and
aerospace markets. 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.  Along  with  this,  we  offer  consulting  services,
which  we  bring  to  the  market  as  Mindware,  which  helps  customers  to  adopt  3D  printing  in  their  business  before  they  can  even  start
printing.

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  provides  quotations,  takes  orders,  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, medtech, 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.

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  training  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. 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  Sculpteo,  Prototal,  Protolabs  and  Quickparts.  In  addition,  larger  accounts  tend  to  move  their  3D  printing
production in-house once their orders have reached certain volumes, which not only creates opportunities for our Materialise Software
segment but also for our Materialise Manufacturing segment in terms of capacity balancing services.

In the measurement and quality control fixture market addressed by RapidFit+, we are not aware of any direct competition coming from
3D printing companies. We do have competition, however, from a large group of smaller companies that are active in the more traditional
tooling manufacturing.

Growth Opportunities. We believe that there is particular potential to grow our presence in the markets for additive manufacturing of
complex and/or unique end products, including in particular certain parts for the aviation industry, medtech and eyewear and footwear
products.  In  recent  years,  more  companies  have  been  using  additive  manufacturing  for  production  across  a  broad  range  of  industrial
sectors, including aerospace, orthopedic implants, surgical guides, dental copings and hearing devices. For industrial end-use parts, we
intend  to  continue  to  selectively  invest  in  the  expansion  and  creation  of  certified  3D  manufacturing  environments  that  meet  the  high
standards of the specialized segments of the industrial production market that we focus on. In addition, we believe that our local sales
teams,  which  are  near  our  customers,  as  well  as  our  engineering  teams,  which  can  bring  in  additional  expertise  where  required,  are
important and rather unique assets in this market that are worthwhile to continue to invest in.

We  devote  significant  time  and  attention  to  the  quality  control  of  our  products  during  the  printing  process  by  maintaining  a
comprehensive  quality  control  program,  which,  among  other  things,  includes  the  control  and  documentation  of  all  material
specifications, operating procedures, equipment maintenance and quality control methods. In addition, we inspect all of our raw materials
to  be  used  in  our  products  throughout  the  printing  process.  We  control  our  production  orders  through  the  use  of  labels  or  visual
references on our internal database, bar-codes, controlled prints and routers, which enables us to trace our products during the printing
process. Upon completion of the production process, we package and label our products.

The  raw  materials  used  in  the  printing  of  our  products  are  mainly  aluminum,  titanium  alloy  and  stainless  steel  powders,  epoxy  based
photocurable resins, PA12 and thermoplastic polyurethane, or TPU, based powders and a suite of thermoplastic filaments like ABS, PC
and Ultem and quartz sand and furanic resin binder.

With  the  exception  of  FDM,  Stereolithography  and  PolyJet-materials,  we  believe  that  none  of  our  other  raw  material  requirements  is
limited to any significant extent by critical supply or price volatility. We continuously look for second sourcing of our raw materials in
order not to be dependent on a single supplier in case a supply issue was to occur. We monitor the costs of our raw materials in order to
optimize  the  cost/performance  whilst  not  jeopardizing  the  expectations  of  our  customers  and  the  safe  use  of  the  materials  in  critical
applications.  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,  and  mechanical  and
biomedical engineering.

We  have  a  long  history  of  research  and  development  through  collaborations,  which  augment  our  internal  development  efforts.  As  of
December 31, 2023, 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,  2023,  we  had  more  than  50  active  research  and  development  projects  in  various  stages  of  completion  and
approximately  540  FTEs  and  fully  dedicated  consultants  working  on  research  and  development  in  our  facilities  in  Belgium,  France,
Germany, Spain, the United Kingdom, the United States, Colombia, Ukraine and Malaysia.

Our research and development projects include (but are not limited to) the following:

1.

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);

3.

research projects in our Materialise Medical segment to develop patient specific surgical planning tools or surgical guides
or implants for orthopedic, CMF and cardiovascular surgeries;

48

Table of Contents

4.

5.

6.

7.

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,  2023,  our  portfolio  of  intellectual  property  featured  476  issued  patents  and  an  additional  101  pending  patent
applications primarily in the United States, the European Union and Japan. Of these, our issued patents expire between approximately
2023 and 2040, 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  “CO-AM,”  “Mimics,”  “3-
matic,”  “Inspector,”  “Magics,”  “RapidFit+,”  “Heartprint,”  “ADaM,”  “Surgicase,”  “Enlight,”  “Mindware,”  “Streamics,”  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.

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.

ITEM 5. OPERATING AND FINANCIAL REVIEW AND PROSPECTS

This  section  contains  forward-looking  statements  that  involve  risks  and  uncertainties.  Our  actual  results  could  differ  materially  from
those  contained  in  forward-looking  statements.  Factors  that  could  cause  or  contribute  to  such  differences  include,  without  limitation,
those  discussed  in  the  sections  entitled  “Item  3.  Key  Information—D.  Risk  Factors,”  “Special  Note  Regarding  Forward-Looking
Information” and “Item 4. Information on the Company—B. Business Overview” and elsewhere in this annual report.

A. Operating Results

Overview

Company Overview

We  are  a  leading  provider  of  additive  manufacturing  and  medical  software  tools  and  of  sophisticated  3D  printing  services.  With  our
knowledge, products and services, we empower our customers to use additive manufacturing technology more effectively, in general, and
we enable certain specific and significant applications of additive manufacturing, in particular. In both instances, we seek to empower the
choice for sustainability through the use of additive manufacturing.

The  customers  of  our  general  software  tools  and  3D  printing  services  are  active  in  a  wide  variety  of  industries,  including  healthcare,
automotive,  aerospace,  art  and  design  and  consumer  products.  The  significant  additive  manufacturing  applications  that  we  are  more
deeply  and  more  directly  involved  in  currently  include  applications  for  orthopedic,  cranio  maxillo  facial,  eyewear,  footwear  and
measurement fixtures.

As  of  December  31,  2023,  our  team  consisted  of  2,437  FTEs  and  fully  dedicated  consultants.  Our  portfolio  of  intellectual  property
featured 476 issued patents and 101 pending patent applications as of December 31, 2023. For the year ended December 31, 2023, we
generated  €  256.1  million  of  revenue,  representing  10%  increase  over  the  prior  year,  a  net  profit  of  €  6.7  million  and  an  Adjusted
EBITDA of € 31.4 million. For a description of Adjusted EBITDA and a reconciliation of our net profit to our Adjusted EBITDA, see
“—Other Financial Information” below.

Public Offering

On July 6, 2021, we closed a follow-on public offering of a total of 4,600,000 ADSs at a public offering price of $24.00 per ADS for
gross proceeds of $ 110.4 million.

We  raised  approximately  $  105.0  million  (or  €  92.7  million,  based  on  the  exchange  rate  as  of  December  31,  2021)  in  aggregate  net
proceeds from such follow-on offering.

Link3D Acquisition

On April 9, 2021, we acquired an option to buy Link3D Inc., which we exercised on November 15, 2021. We closed the acquisition on
January 4, 2022. This acquisition was effected by our U.S. subsidiary, Materialise USA, LLC, by exercising the call option. As a result of
this transaction, Materialise USA became the sole shareholder of Link3D, and subsequently Link3D was merged into Materialise USA.
Link3D was an additive workflow and digital manufacturing software company. The acquisition of Link3D is intended to strengthen and
accelerate the creation of the Materialise software platform.

Identify3D Acquisition

On  September  1,  2022,  we  acquired  Identify3D,  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,  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) 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.

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.

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.

Key Income Statement Items

Revenue

Revenue is generated primarily by the sale of our software and 3D printed and complex manufactured products and services.

In  our  Materialise  Software  segment,  we  generate  revenues  from  software  licenses,  maintenance  contracts  and  custom  software
development services and sales of Materialise Controller.

In  our  Materialise  Medical  segment,  we  generate  revenue  through  the  sale  of  medical  devices  that  we  print  or  manufacture  for  our
customers  and  from  the  sale  of  licenses  on  our  medical  software  packages,  software  maintenance  contracts  and  custom  software
development and engineering services.

In our Materialise Manufacturing segment, we generate most of our revenue through the sale of parts that we print or produce for our
customers.

Software. Software revenue is comprised of perpetual and time-based licenses, maintenance revenue and software development service
fees. Our software products are mainly licensed pursuant to one of two payment structures: (i) perpetual licenses, for which the customer
pays an initial fee for a perpetual license and subsequently pays fees for maintenance under separate maintenance contracts, generally on
an  annual  basis,  or  (ii)  time-based  licenses  (generally  annual  licenses),  for  which  the  customer  pays  equal  periodic  fees  to  keep  the
license  active.  Perpetual  licenses  require  the  payment  of  fees  for  maintenance,  technical  support  and  product  updates.  Time-based
licenses entitle the customer to corrective maintenance and product updates without additional charge. We generally recognize revenue
from our time-based licenses and our maintenance revenue on a straight-line basis over the term of the applicable license or maintenance
contracts.  Our  software  revenue  depends  upon  both  incremental  sales  of  software  licenses  to  both  new  and  existing  customers  and
renewals  of  existing  time-based  licenses  and  maintenance  contracts.  Sales  and  renewals  are  also  driven  by  our  customers’  usage  and
budget cycle. Software development services are typically charged either on a time and materials basis or on a fixed fee basis.

3D printed products and services. 3D printed products revenue is derived from our network of 3D printing service centers. Our service
centers not only utilize our 3D printing technology to print products but are also full-service operations that provide support and services
such  as  pre-production  collaboration  prior  to  printing  the  product.  Revenue  from  3D  printed  products  depends  upon  the  volume  of
products that we print for our customers. Sales of these products are linked to the number of our 3D printing machines that are installed
and active worldwide. We have dedicated teams and production lines for industrial applications and medical applications. All medical
products require a highly regulated production environment. Whereas both segments use the same 3D printing technologies, the complex
combination of our engineering and software solutions in connection with medical applications results in higher margins for our medical
applications.

Production of limited runs of highly complex casted metal parts. Casted products revenue is derived from ACTech’s network, with its
production unit in Freiberg, Germany. ACTech is utilizing casting technology, including 3D printing technology for mold making, and
offers full-service project operations, including project and pre-production collaboration, and high-end complex finishing services.

Cost of Sales

Our cost of sales includes raw materials, external subcontracting services, labor costs, manufacturing overhead expenses, amortization
and  depreciation  and  reserves  for  inventory  obsolescence.  Our  manufacturing  overhead  expenses  include  quality  assurance,
manufacturing  engineering,  material  procurement,  inventory  control,  facilities,  equipment  and  information  technology  and  operations
supervision and management.

Research and Development Expenses

Our  research  and  development  activities  primarily  consist  of  engineering  and  research  programs  associated  with  our  products  under
development  as  well  as  research  and  development  activities  associated  with  our  core  technologies  and  processes.  Research  and
development expenses are primarily related to employee compensation, including salary, fringe benefits, share-based compensation and
temporary  employee  expenses.  We  also  incur  expenses  for  software  and  materials,  supplies,  costs  for  facilities  and  equipment,
depreciation, and outside design and outside research support.

Development expenditures on an individual project are recognized as an intangible asset when we can demonstrate:

● the technical feasibility of completing the intangible asset so that the asset will be available for use or sale;

● the intention to complete and the ability to use or sell the asset;

● how the asset will generate future economic benefits;

● the availability of resources to complete the asset; and

● the ability to measure reliably the expenditure during development.

We have determined that the conditions for recognizing internally generated intangible assets from proprietary software, guides and other
product  development  activities  are  not  met  until  shortly  before  the  products  are  available  for  sale,  unless  either  (i)  we  have  strong
evidence that the above criteria are met and a detailed business plan is available showing the asset will on a reasonable basis generate
future economic benefits or (ii) the development is done based upon specific request of the customer, we have the intention to market the
product  to  parties  other  than  the  customer,  the  development  is  subject  to  an  agreement  and  the  substance  of  the  agreement  is  that  the
customer reimburses us for a significant portion of the development expenses incurred. As such, development expenditures not satisfying
the  above  criteria  and  expenditures  on  the  research  phase  of  internal  projects  are  recognized  in  the  consolidated  income  statement  as
incurred.

Sales and Marketing Expenses

Our  sales  and  marketing  expenses  primarily  consist  of  employee  compensation,  including  salary,  fringe  benefits  and  share-based
compensation  for  our  marketing,  sales  and  business  development  functions.  Other  significant  expenses  include  travel,  depreciation,
product demonstration samples, brochures, websites and trade show expenses.

General and Administrative Expenses

Our general and administrative expenses primarily consist of employee compensation, including salary, fringe benefits and share-based
compensation  for  our  executive,  financial,  human  resources,  information  technology  support  and  regulatory  affairs  and  administrative
functions.  Other  significant  expenses  include  outside  legal  counsel,  independent  auditors  and  other  outside  consultants,  insurance,
facilities, depreciation and information technologies expenses.

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.

57

Table of Contents

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.

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.

58

Table of Contents

We  make  significant  judgments  when  performing  the  assessment  of  whether  a  performance  obligation  is  distinct  from  the  other
performance obligations in a contract, i.e., whether the good or service has a benefit to the customer on its own or together with readily
available  resources  and/or  whether  the  good  or  service  is  highly  interrelated  or  constitutes  a  significant  input  with  another  good  or
service provided, or whether it significantly modifies or tailors another good or service. Relevant judgments include the following:

● Whether  the  software  license  is  distinct  from  the  3D  printed  guides  –  in  most  cases  with  contracts  with  collaborative
partners in the Materialise Medical segment, the software license is combined with the manufacturing of the 3D printed
guides  as  the  software  license  has  no  benefit  to  the  customer  without  the  manufacturing  services.  We  have  also
implemented a new “Plan Only” feature where the collaboration partners can benefit from a virtual plan produced with the
software license without the manufacturing of any physical product. Such Plan Only features are recognized in revenue as a
separate performance obligation based on the usage by the collaboration partner.

● Whether  the  development  services  are  distinct  from  other  performance  obligations  –  in  most  cases,  these  performance
obligations  are  distinct  however  for  one  contract  with  a  collaboration  partner  in  the  Materialise  Medical  segment,  the
software license is combined with the license and the 3D printed guides as one “distinct” performance obligation.

For the stand-alone selling prices, we use prices from price list or historical prices for similar transactions. However, in certain cases,
such information may not be readily available, and in those cases, we estimate the stand-alone selling price based on a cost-plus mark-up
or other estimate. If the stand-alone selling price of one or more goods or services in arrangements with multiple performance obligations
is highly variable or uncertain, we estimate the stand-alone selling price with reference to the total transaction price less the sum of the
observable stand-alone selling prices of other goods or services promised in the contract. In addition, for certain performance obligations
such as development services, the stand-alone selling prices also require an estimate of the time required to complete the development.

Certain contracts include estimates of variable considerations within the transaction price and assessing the revenue constraint, such as:

● quantities/volume  sold  at  fixed  prices  related  to,  but  not  limited  to,  the  manufacturing  of  3D  printed  products,  software

licenses sold and maintenance renewals;

● contractual prices may vary based on volume purchased during a given period;

● FTE expenses for development or other services billed on a time & material basis; and

● volume rebates.

The method used to estimate the variable consideration depends on the number of possible scenarios and the probability of each scenario.
If there are many possible scenarios with a high probability probabilities (each less than 50)%, we will use the expected value method,
while the most likely method is used when there is a scenario with a higher probability (more than 50)%.

Variable consideration is not a constraint when, based on historical experience, a high reliable business forecast and/or the timeframe of
the estimates, we determine that there is a high probability that it will not result in a future reversal of revenue.

We determine the stage of completion for development contracts satisfied over time by comparing the labor hours incurred to date with
the estimated total labor hours required to complete the project. We consider labor hours to be the most reliable, available measure of
progress on these projects. Adjustments to estimates to complete are made in the periods when facts that give rise to a change become
known. When the estimate indicates that a loss will be incurred, the loss is recorded in the relevant period. Significant judgments and
estimates  are  involved  in  determining  the  percentage  completion  for  each  contract.  Different  assumptions  can  produce  materially
different results.

Development Expenses

Under  International  Accounting  Standards  38,  or  IAS  38,  internally  generated  intangible  assets  from  the  development  phase  are
recognized if certain conditions are met. These conditions include the technical feasibility, the intention to complete, the ability to use or
sell the asset under development, the availability of technical, financial and other resources to complete the asset, and the demonstration
of  how  the  asset  will  generate  probable  future  economic  benefits.  The  cost  of  a  recognized  internally  generated  intangible  asset
comprises all directly attributable cost necessary to make the asset capable of being used as intended by management. In contrast, all
expenditures arising from the research phase are expensed as incurred.

Determining  whether  internally  generated  intangible  assets  from  development  are  to  be  recognized  as  intangible  assets  requires
significant  judgment,  particularly  in  determining  whether  the  activities  are  considered  research  activities  or  development  activities,
whether  the  product  enhancement  is  substantial,  whether  the  completion  of  the  asset  is  technically  feasible  considering  a  company-
specific approach and the likelihood of future economic benefits from the sale or use.

We have determined that the conditions for recognizing internally generated intangible assets from proprietary software, guide and other
product  development  activities  are  not  met  until  shortly  before  the  products  are  available  for  sale,  unless  either  (i)  we  have  strong
evidence that the above criteria are met and a detailed business plan is available showing that the asset will generate future economic
benefits  on  a  reasonable  basis  or  (ii)  the  development  is  done  based  upon  specific  request  of  the  customer,  we  have  the  intention  to
market the product also to other parties than the customer, the development is subject to an agreement and the substance of the agreement
is that the customer reimburses us for a significant portion of the development expenses incurred. As such, development expenditures not
satisfying  the  above  criteria  and  expenditures  on  the  research  phase  of  internal  projects  are  recognized  in  the  consolidated  income
statement as incurred. This assessment is monitored on a regular basis.

We  have  determined  that  the  criteria  for  internally  generated  intangible  assets  were  met  for  two  projects  in  2018:  (1)  the  software
development of a new planner for hospitals within the cardiovascular field and (2) the process to obtain FDA and E.U. approval for a 3D
printed  tracheal  splint  within  the  Materialise  Medical  segment.  The  first  project  was  successfully  completed  in  2019.  In  2021,  we
recognized an impairment of € 0.2 million as the business case no longer showed a positive result over the next 5 years. The main reason
was a delay in revenue due to the ongoing COVID-19 pandemic. The second project obtained the Investigational Device Exemption, or
IDE,  approval  from  the  FDA  in  the  first  quarter  of  2024.  Because  the  present  value  of  the  expected  cash  flows  until  2030  remains
negative we continue to report the R&D expenses related to this program in our income statement.

In  the  year  ended  December  31,  2020  we  determined  that  the  criteria  for  internally  generated  intangible  assets  were  met  for  certain
subprojects related to our internal digital transformation program. With this program, we are investing in our IT landscape and upgrading
and/or standardizing part of our digital core business. We have further invested in 2023, and will continue to invest in 2024 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,
2023, we capitalized €7.5 million as software and carried €0.4 million as assets under construction in respect of those projects.

60

Table of Contents

In the year ended December 31, 2021 we determined that the criteria for internally generated intangible assets were met for our project
on the transformation of the platform architecture to enable our software products to make the transition from desktop to (hybrid) cloud.
As of December 31, 2021 we had capitalized K€975 in respect of this project. During 2022 we continued to invest in this project and
added K€984 to the asset under construction. As of December 31, 2022, we recognized an impairment of K€672 in respect of this asset
under construction, due to an overlap with the recently acquired Link3D technology and the fact that this Link3D technology was already
in a more advanced stage. The remaining K€1,287 was transferred from assets under construction to software, and amortization on this
asset started in 2022.

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, 2023, we had current and non-current receivables related to tax credits for an amount of € 5 million (2022: € 5 million;
2021: € 5 million).

As of December 31, 2023, we had € 92 million (2022: € 88 million; 2021: € 58 million) of tax losses carried forward and Innovation
Income Deductions, of which € 47 million related to Materialise NV (2022: € 45 million; 2021: € 36 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.

Under  the  Belgian  Innovation  Income  Deduction  system,  companies  can  deduct  up  to  85%  of  their  net  innovation  income  from  the
taxable basis.

With respect to the tax losses carried forward and Innovation Income Deductions carried forward we recognized at December 31, 2023 a
deferred tax asset of € 0.1 million for Materialise NV (2022: € 0.2 million, 2021: € 0.0 million) and € 1.0 million for Materialise USA
(2022: € 1.6 million, 2021: € 0.0 million).

We have not recognized deferred tax assets on unused tax losses and Innovation Income Deduction totaling € 22 million as at December
31, 2023 (2022: € 19 million; 2021: € 12 million) given that it is not probable that sufficient positive taxable base will be available in the
foreseeable future against which these tax losses and Innovation Income Deduction can be utilized. If all deferred tax assets related to
unused tax losses carried forward and Innovation Income Deduction would meet the criteria for recognition, net result for the year would
have  improved  by  €  22  million  in  2023  through  a  deferred  tax  benefit.  This  would  represent  the  planned  recovery  of  €  88  million  of
unused  tax  losses  carried  forward  and  Innovation  Income  Deduction  in  future  periods.  Further  details  on  taxes  are  disclosed  in  Note
22.10 to our consolidated financial statements.

Impairment of Goodwill, Intangible Assets and Property, Plant and Equipment

We have goodwill for a total amount of € 43.2 million as of December 31, 2023 (2022: € 44.2 million; 2021: € 18.7 million) which has
been subject to an impairment test. Goodwill is tested for impairment based on a discounted cash flow model with cash flows for the next
five years derived from the budget, and a residual value considering a perpetual growth rate. The value in use is sensitive to the discount
rate  used  for  the  discounted  cash  flow  model  as  well  as  the  expected  future  cash-inflows  and  the  growth  rate  used  for  extrapolation
purposes. The key assumptions used to determine the value in use for the different cash generating units, or CGUs, are disclosed and
further explained in Note 5 to our consolidated financial statements.

When events or changes in circumstances indicate that the carrying amount of the intangible assets and property, plant and equipment
may not be recoverable, we estimate the value in use for the individual assets, or when not possible, at the level of CGUs to which the
individual assets belong. Total impairment charges recorded during 2023 were € 4.2 million (2022: € 0.7 million; 2021: € 0.2 million).

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.

In  2022,  we  recorded  impairment  charges  of  €  0.7  million  related  to  the  transformation  of  the  platform  architecture  to  enable  our
software products to make the transition from desktop to cloud-based.

In  2023,  we  recorded  a  goodwill  impairment  of  €  4.2  million  related  to  Materialise  Motion  and  Engimplan.  On  the  CGU  Materialise
Motion in Belgium, it was concluded that the value in use was lower than the carrying value, which resulted in a full impairment of the
goodwill  for  an  amount  of  €  1.2  million  as  well  as  a  partial  impairment  on  the  intangible  assets  related  to  the  partnership  agreement,
customer list, and developed technology for respectively € 0.9 million, € 0.1 million, and € 1.4 million. The key elements that led to the
impairment loss for the Motion CGU was the delay in business growth versus what was initially foreseen. On the CGU Engimplan in
Brazil, it was concluded that the value in use was lower than its carrying value, which resulted in a full impairment of the intangible
assets related to customer list and trademarks for respectively € 0.4 million and € 0.1 million as well as a tangible asset 3D printer for €
0.1 million. The key elements that led to the impairment loss for the Engimplan CGU were related to a delay in business growth and to
less benefits of synergies than initially anticipated.

Business Combinations

We determine and allocate the purchase price of an acquired business to the assets acquired and liabilities assumed as of the business
combination date. The purchase price allocation process requires us to use significant estimates and assumptions, including:

● estimated fair value of the acquired intangible assets;

● estimated fair value of property, plant and equipment; and

● estimated fair value of the contingent consideration.

The contingent consideration as included in the financial statements is recorded at fair value at the date of acquisition and is reviewed on
a regular basis, at least annually. The fair value of the contingent consideration is based on risk-adjusted future cash flows of different
scenarios discounted using appropriate interest rates. The structure of the possible scenarios and the probability assigned to each one of
them  is  reassessed  by  management  at  every  reporting  period  and  requires  judgement  from  management  about  the  outcome  and
probability of the different scenarios as well as the evolution of the variables.

While we are using our best estimates and assumptions as part of the purchase price allocation process to accurately value assets acquired
and  liabilities  assumed  at  the  date  of  acquisition,  our  estimates  and  assumptions  are  inherently  uncertain  and  subject  to  refinement.
Examples of critical estimates in valuing certain of the intangible assets we have acquired or may acquire in the future, include but are
not limited to:

● future expected cash flows from customer contracts and relationships, software license sales and maintenance agreements;

● the fair value of the plant and equipment;

62

Table of Contents

● 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 € 3.7 million at December 31, 2023. 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
13.32%  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.

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 from our Materialise Medical segment increased € 16.5 million, or 19.5%, from € 84.8 million in the year ended December 31,
2022, to € 101.4 million in the year ended December 31, 2023. Within our medical software department recurrent revenue from annual
and renewed licenses and maintenance fees increased by € 4.7 million, or 20.3%, reflecting the implementation of our continued strategy
focused on products with defined contractual periods. These recurrent revenues represented 87.2% of all medical software revenues in
the year ended December 31, 2023, compared to 84.8% in the year ended December 31, 2022. Our non-recurrent revenue from perpetual
licenses  and  services  remained  consistent  in  the  year  ended  December  31,  2023,  compared  to  the  year  ended  December  31,  2022.
Deferred revenue from license and maintenance fees amounted to € 0.7 million in the year ended December 31, 2023, compared to € 5.1
million in the year ended December 31, 2022. Revenues from medical devices and services grew by € 11.9 million, or 20.6%, in the year
ended December 31, 2023, driven by growth in all of our sales channels across our different core markets. As of December 31, 2023, our
Materialise Medical segment operated 50 3D printers, as compared to 49 as of December 31, 2022.

Revenue  from  our  Materialise  Manufacturing  segment  increased  €  6.8  million,  or  6.6%,  from  €  103.5  million  in  the  year  ended
December 31, 2022, to € 110.3 million in the year ended December 31, 2023. Materialise Manufacturing operated 157 3D printers, 28
CNC machines and 5 vacuum casting machines as of December 31, 2023, compared to 156 3D printers, 22 CNC machines and 6 vacuum
casting machines as of December 31, 2022, respectively.

Cost of sales. Cost of sales was € 111.0 million in the year ended December 31, 2023, compared to € 103.3 million in the year ended
December  31,  2022,  representing  an  increase  of  €  7.7  million,  or  7.5%.  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 € 16.4 million from € 128.8 million in the year ended December 31, 2022, to € 145.1 million in the
year  ended  December  31,  2023,  mainly  driven  by  increased  revenue  in  all  three  Materialise  segments,  partially  offset  by  higher
production costs. The overall gross profit margin (gross profit divided by our revenue) amounted to 56.7% in the year ended December
31, 2023, compared to 55.5% in the year ended December 31, 2022.

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 decreased, in the aggregate, to € 133.0 million in the year ended December 31, 2023, compared to € 134.8 million in the
year ended December 31, 2022. R&D expenses increased from € 37.6 million to € 38.1 million, or 1.4%.S&M expenses decreased from
€  62.1  million  to  €  57.8  million,  or  6.9%,  driven  by  our  Materialise  Software  segment  sales  reorganization.  G&A  expenses  increased
from € 35.1 million to € 37.1 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 a negative € 6.5 million, in the year ended December 31, 2023,
compared to a positive € 3.2 million net other operating income in the year ended December 31, 2022. The main drivers of this decrease
were an arbitration settlement of € 5.2 million, an impairment loss related to intangible assets of € 3.0 million, an impairment loss related
to goodwill of € 1.2 million, and an amortization expenses of acquired intangible assets, which represented an expense of € 4.0 million
for the year ended December 31, 2023, compared to € 5.1 million for the year ended December 31, 2022. These expenses were partially
offset by witholding tax exemptions (€ 3.0 million), grants received (€ 1.8 million), and R&D tax credits (€ 1.4 million).

Net financial income (financial income and financial expense). Net financial income was € 1.2 million in the year ended December 31,
2023, compared to a net income of € 1.7 million in the year ended December 31, 2022. In 2023, the net positive result was mainly due to
increased interest income on short-term deposits from higher prevailing interest rates, partially offset by increased interest expense on
our loans and borrowings.

Income taxes. Income taxes in the year ended December 31, 2023 resulted in an expense of € 0.1 million, which was a combination of
deferred tax benefits amounting to € 2.3 million and current income tax expenses of € 2.4 million.

Net profit/loss.  As  a  result  of  the  factors  described  above,  net  profit  amounted  to  €  6.7  million  in  the  year  ended  December  31,  2023
compared to a net loss of € 2.2 million in the year ended December 31, 2022.

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.

compared  to  €  19.2  million  in  the  year  ended  December  31,  2022,  an  increase  of  €  8.0  million.  During  2023,  we  continued  to
strategically invest in our growth businesses and progressed on our transition to cloud-based annual license revenue in our Materialise
Software segment. In 2023, revenue increased by 10.4%. Our 2023 EBITDA included expenses of € 4.2 million from the impairment of
goodwill (€ 1.2 million) and partial impairment of the intangible assets (€ 2.4 million) of Materialise Motion NV and the impairment of
intangible and tangible assets (€ 0.7 million) of Engimplan. These expenses were, among others, not reflected in our Adjusted EBITDA.
Our consolidated Adjusted EBITDA was € 31.4 million in the year ended December 31, 2023, compared to € 19.0 million in the year
ended December 31, 2022, an increase of € 12.4 million.

the segment’s revenue) increased to 16.8% in the year ended December 31, 2023, from 3.5% for the year ended December 31, 2022. The
increase in the Adjusted EBITDA margin was the result of cost containment efforts while further investing in R&D expenses.

Our Materialise Medical segment’s Adjusted EBITDA amounted to € 26.5 million in the year ended December 31, 2023, compared to €
18.8  million  in  the  year  ended  December  31,  2022.  The  segment’s  Adjusted  EBITDA  margin  increased  to  26.2%  in  the  year  ended
December 31, 2022 from 22.2% in the year ended December 31, 2022. The increase in the segment’s Adjusted EBITDA margin was as a
result of increased revenues while keeping costs under control.

compared to 57.5% in the year ended December 31, 2021.

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

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 annual
license revenue in our Materialise Software segment. 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.

Our  Materialise  Software  segment’s  Adjusted  EBITDA  was  €  15.7  million  in  the  year  ended  December  31,  2021  compared  to  €  1.5
million in the year ended December 31, 2022, a decrease of € 14.2 million. This segment’s Adjusted EBITDA margin (the segment’s
Adjusted EBITDA divided by the segment’s revenue) decreased to 3.5% in the year ended December 31, 2022, from 36.6% for the year
ended December 31, 2021. 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.

B. Liquidity and Capital Resources

Prior  to  our  initial  public  offering,  we  historically  funded  our  operations  principally  from  cash  generated  from  operations  and
borrowings. From our initial public offering on June 30, 2014 through December 31, 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. 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.

We  expect  our  main  uses  of  cash  in  the  future  will  be  funding  our  business  operations,  capital  expenditures,  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 year ended December 31, 2022, a decrease of € 2.1 million, or 9.6%. In the year ended December 31, 2023, the net cash flow from
operating activities was the result of the income statement cash result of € 32.8 million, decreased by working capital requirements of €
13.1 million, offset by increased deferred revenue of € 0.5 million.

Net cash flow used in investing activities was € 11.0 million in the year ended December 31, 2023 compared to € 53.9 million in the year
ended  December  31,  2022,  a  decrease  of  €  42.8  million,  or  79.5%.  The  decrease  was  mainly  due  to  the  acquisition  of  Link3D  and
Identify3D (€ 29.3 million) in 2022 and no comparable acquisition activity occurring in 2023.

Net cash flow used in financing activities was € 22.4 million in the year ended December 31, 2023, compared to € 22.5 million in net
cash flow from financing activities in the year ended December 31, 2022. 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 2023, while our repayment of borrowings
and leases amounted to € 20.3 million.

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

drawdowns were made under this new facility in 2022, while our repayment of borrowings and leases amounted to € 21.1 million.

All loan drawings were contracted at a fixed interest rate, and a reservation cost for the 3 tranches amounts is applicable at 0.15% per
year. As of December 31, 2023, no amounts had been drawn under this facility.

K€35,000 EIB bank loan

On December 20, 2017, we entered into a finance contract with the European Investment Bank, or EIB, to finance future research and
development programs. The contract provides a credit of up to € 35.0 million drawable in two tranches. As part of the first tranche, an
amount of €10.0 million was drawn in July of 2018. 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.

K€17,700 secured bank loans

The € 17.7 million loan has been concluded in 2016 in two agreements to finance the construction of new facilities in Leuven (Belgium)
and in Poland, both maturing in 2032. The agreement for the Belgian facility financing amounts to € 11.7 million, and repayments started
in June 2023. The agreement for the Polish facility financing amounts to € 6.0 million (fully drawn per end of 2020), and repayments
started in June 2019. The average interest rate of both agreements amounts to 1%. The bank loan is secured with a mortgage mandate on
the Belgian facility buildings.

K€12,300 bank loans

In  March  2018,  three  bank  loans  originating  from  the  acquired  ACTech  business  were  refinanced  in  their  entirety  for  an  aggregate
amount of € 9.3 million, with the maturity adjusted to May 2025 and the first repayments beginning in August 2020. The interest rate
was fixed at approximately 1.6%, and pledges including a € 4.7 million mortgage on ACTech’s facilities and guaranteed by Materialise
NV.  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 € 1.5 million as of December 31, 2023. 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, 2023 amount to a balance of € 4.8 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%.

K€7,943 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. As of December 31, 2023 the balance of these lease obligations amounts to € 7.9 million,
and are mostly at fixed interest rates with weighted average below 1%.

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,  2023  were  K€64  (2022:  K€96;  2021:
K€128). The interest expense for the year ended December 31, 2023 was K€3 (2022: K€5; 2021: K€5).

Material Unused Sources of Liquidity

Our  cash  and  cash  equivalents  as  of  December  31,  2023,  2022  and  2021  were  €  127.6  million,  €  140.9  million  and  €  196.0  million,
respectively. We have one undrawn line of credit at December 31, 2023, a credit facility agreement with KBC, which provides for a € 50
million delayed draw. 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 general limitations imposed by the corporate laws and certain
restrictions in the jurisdictions that we operate in. For example, China has very specific approval regulations for all capital transfers to or
from the country, certain capital transfers to and from Ukraine are subject to obtaining a specific permit and current legislation in Brazil
permits  the  Brazilian  government  to  impose  temporary  restrictions  on  remittances  of  foreign  capital  abroad  in  the  event  of  a  serious
imbalance or an anticipated serious imbalance in Brazil’s balance of payments. Dividends paid to us by certain of our subsidiaries may
also be subject to withholding taxes in certain jurisdictions. Of our cash and cash equivalents held outside of Belgium as of December
31, 2023, 2022 and 2021, 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.

of the armed conflict in Ukraine, our operations from our Kyiv office operate in very difficult, uncertain and unstable circumstances.

To-date, most of our personnel from the office in Kyiv have continued to work for us throughout the armed conflict, either remotely from
Ukraine  or  other  neighboring  countries,  from  our  Wroclaw  office  or,  circumstances  permitting,  from  our  office  in  Kyiv,  while  others
remain unable to perform their work. As of the date of this annual report, we have been able to continue servicing our customers without
significant  disruption  or  delay,  as  personnel  with  similar  skills  and  competencies  located  elsewhere  in  the  world  have  increased  their
roles and responsibilities to assist displaced personnel.

As the armed conflict with Russia continues, it is impossible to predict how much of our Ukrainian workforce will be able or willing to
continue working for us. As we are unable to predict how the armed conflict in Ukraine will evolve, we cannot exclude that delays or
disruption in certain of our services may occur or that a more radical, temporary shift of certain operations to other jurisdictions may
become necessary, which could impact our business and operations, results of operations, financial condition, cash flows and liquidity.

We have incurred, and will continue to incur, expenses related to hiring additional and more expensive resources outside Ukraine.

It is uncertain to what extent some of the development projects of our Materialise Software and Materialise Medical segments, and to a
lesser  extent  our  Materialise  Manufacturing  segment,  will  be  impacted  by  the  ongoing  armed  conflict  in  Ukraine.  As  a  result  of  such
impact, some of our anticipated product releases may be delayed, which may adversely affect our revenue.

As of the date of this annual report, we are unable to predict how the armed conflict in Ukraine will evolve or what the impact of any
political and direct and indirect economic repercussions will be on the global economy and our business. Indirect economic repercussions
could, for example, come from continued or further increased inflation, or currencies instability. As a result, we are unable to assess with
certainty its impact on our business and operations, results of operations, financial condition, cash flows and liquidity.

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.

The term of the directorship of each member of our board of directors will expire at the 2024 annual general meeting of shareholders.
The business address of the members of our board of directors is the same as our business address: Technologielaan 15, 3001 Leuven,
Belgium.

Our board of directors has determined that Jürgen Ingels, Bart Luyten, Volker Hammes and Lieve Verplancke are independent under both
Belgian  law  and  the  Nasdaq  Stock  Market  Listing  Rules.  The  Belgian  law  definition  of  independence  differs  from  the  definition  of
independence  under  Nasdaq  Stock  Market  Listing  Rules.  In  particular,  under  Belgian  law,  A  Tre  C  CVOA  (represented  by  Johan  De
Lille) and Jos Vander Sloten are no longer deemed independent by virtue of its term of office exceeding 12 years. However, the Nasdaq
Stock  Market  Listing  Rules  do  not  have  a  similar  requirement,  and  our  board  of  directors  has  determined  that  A  Tre  C  CVOA
(represented by Johan De Lille) and Jos Vander Sloten continue to be independent under the Nasdaq Stock Market Listing Rules.

B. Compensation

Compensation of Directors

Our Remuneration and Nomination Committee recommends the level of remuneration for directors. These recommendations are subject
to  approval  by  our  board  of  directors  and,  subsequently,  by  our  shareholders  at  the  annual  general  meeting.  During  the  year  ended
December  31,  2023,  only  the  directorships  of  Mr.  De  Lille,  Mr.  Vander  Sloten,  Mr.  Ingels,  Mr.  Luyten,  Ms.  Verplancke,  Mr.  Sander
Vancraen  and  Mr.  Hammes  were  remunerated.  The  directorships  of  Mr.  Wilfried  Vancraen,  Mr.  Leys  and  Ms.  Ingelaere  were  not
remunerated because these individuals were remunerated in their capacity as senior management. During the year ended December 31,
2023, Mr. De Lille, Mr. Vander Sloten, Mr. Ingels, Mr. Luyten, Ms. Verplancke, Mr. Sander Vancraen and Mr. Hammes each received
annual remuneration equal to € 11,000. In addition, Mr. De Lille, Mr. Vander Sloten, Mr. Ingels, Mr. Luyten, Ms. Verplancke, Mr. Sander
Vancraen and Mr. Hammes each received a remuneration of € 1,375 per physical board meeting that he or she attended and € 687.5 for
each board meeting held via conference call (lasting more than one hour) that he or she attended.

In addition, the Chairman of the Audit Committee received an annual remuneration of € 8,250. Each independent member (including the
Chairman)  of  the  Audit  Committee  or  the  Remuneration  and  Nomination  Committee  received  a  remuneration  of  €  1,375  for  each
physical committee meeting that he or she attended, and € 687.5 for each committee meeting held via conference call (lasting more than
one hour) and that he or she attended. The Remuneration and Nomination Committee benchmarks directors’ compensation against peer
companies to ensure that it is competitive. In addition, our board of directors sets and revises, from time to time, the rules and level of
compensation for directors carrying out a special mandate or sitting on one or more of the board of directors committees and the rules for
reimbursement of directors’ business-related out-of-pocket expenses.

Compensation of Senior Management and Executive Committee

In 2023, the aggregate total gross compensation of our senior management amounted to € 2.6 million, which included base salary, bonus
payments,  company  car  allowance  and  other  benefits.  This  amount  also  includes  the  compensation  for  the  members  of  the  Executive
Committee. During 2023, the directorships of Mr. Wilfried Vancraen, Mr. Leys and Ms. Ingelaere were not remunerated.

We have entered into services agreements (Contracts for Paid Office as a member of the Executive Committee) with each member of our
Executive Committee. The terms of these agreements are substantially similar. These agreements generally provide for an annual base
salary. In addition to the fixed remuneration components, under the terms of these agreements, members of our Executive Committee are
entitled  to  certain  additional  benefits  (including  mobile  phone  and  director  and  officer  liability  insurance)  and  reimbursement  of
necessary  and  reasonable  expenses.  These  services  agreements  with  members  of  our  Executive  Committee  provide  for  payments  and
benefits (including upon termination of employment) that we believe are in line with customary market practice for similar companies
who are operating in our industry.

C. Board Practices

Service Contracts

Except  as  described  above  under  “—B.  Compensation—Compensation  of  Senior  Management  and  Executive  Committee,”  we  do  not

Decisions  are  generally  made  by  our  board  of  directors  as  a  whole.  However,  decisions  on  certain  matters  may  be  delegated  to
committees  of  our  board  of  directors  or  to  the  Executive  Committee  to  the  extent  permitted  by  law  and  our  restated  articles  of
association.  The  chairperson,  or  if  he  or  she  is  prevented  from  doing  so,  the  vice  chairperson,  chairs  the  meetings  of  our  board  of
directors.

Our board of directors transferred management powers to the Executive Committee, except for the general policy of the company and
other powers which are reserved by Belgian company law to the board of directors. The Executive Committee is supervised by our board
of directors. The following actions are comprised under general policy of our company and are thus excluded from the powers of the
Executive Committee:

● mergers and acquisitions;

81

Table of Contents

● transfer and waive of intellectual property rights to third parties;

● granting of exclusivity rights to third parties with an important impact on the freedom of a particular business segment;

● nomination and removal of members of the Executive Committee;

● opening of offices abroad and nomination and removal of managers thereof;

● conclusion of financial loans;

● sale and purchase of real estate; and

● cancellation of a particular product line.

As from January 1, 2024, our board of directors entrusted the daily management of the company to De Vet Management BV, represented
by  Brigitte  de  Vet-Veithen,  our  Chief  Executive  Officer,  in  conformity  with  article  7:121of  the  Belgian  Companies  and  Associations
Code. Until December 31, 2023, this position was held by Wilfried Vancraen.

Pursuant to our restated articles of association, our board of directors may form committees from among its members and charge them
with the performance of specific tasks. The committees’ tasks, authorizations and processes are determined by our board of directors.
Where permissible by law and our restated articles of association, important powers of our board of directors may also be transferred to
committees.

Audit Committee

The Audit Committee consists of three members: Johan De Lille (Chairman), Bart Luyten and Jürgen Ingels. Our board of directors has
determined that Messrs. De Lille, Luyten and Ingels are independent under Rule 10A-3 of the Exchange Act and the applicable rules of
the  Nasdaq  Stock  Market  and  that  each  of  Messrs.  De  Lille,  Luyten  and  Ingels  qualifies  as  an  “audit  committee  financial  expert”  as
defined under the Exchange Act.

Our Audit Committee assists our board of directors in overseeing the accuracy and integrity of our accounting and financial reporting
processes and audits of our consolidated financial statements, the implementation and effectiveness of an internal control system and our
compliance with legal and regulatory requirements, the independent auditors’ qualifications and independence and the performance of
the independent auditors.

The Audit Committee’s duties and responsibilities to carry out its purposes include, among others:

● the review of our accounting processes;

● the review of the effectiveness of our internal systems of control, risk management and compliance;

● the  consideration  and  recommendation  of  the  nomination,  compensation,  retention  and  termination  of  the  Company’s
statutory  auditor  for  Belgian  company  law  purposes  and  the  Company’s  independent  auditor  for  SEC  purposes,  the
commissioning of the auditors to conduct audits, agreeing on additional services to be provided by the auditors under their
respective  engagements,  the  establishment  of  the  scope  and  the  main  review  points  of  the  audit  and  oversight  of  the
auditors’ work (including resolution of disagreements with the auditors);

● the preparation of our board of directors’ resolution on our consolidated financial statements;

● reviewing  our  interim  consolidated  financial  statements  that  are  made  public  or  otherwise  filed  with  any  securities

regulatory authority;

● discussing any flaws relating to our internal control systems, as reported by our board of directors to the audit committee;

● monitoring our bookkeeping and records; and

82

Table of Contents

● the establishment of procedures for (i) the receipt, retention and treatment of complaints we receive regarding accounting,
internal  accounting  controls  or  auditing  matters  and  (ii)  the  confidential,  anonymous  submission  by  our  employees  of
concerns regarding questionable accounting or auditing matters.

Our Audit Committee is entitled to review information on any point it wishes to verify, and is authorized to acquire such information
from any of our employees. It is also authorized to obtain independent advice, including legal advice, if this is necessary for an inquiry
into any matter under its responsibility. It is entitled to call on the resources that would be needed for this task. It is entitled to receive
reports directly from the auditors, including reports with recommendations on how to improve our control processes.

Remuneration and Nomination Committee

Our  Remuneration  and  Nomination  Committee  consists  of  three  members:  Wilfried  Vancraen,  Jozef  Vander  Sloten  and  Lieve
Verplancke. As from January 1, 2024, Hilde Ingelaere has replaced Wilfried Vancraen as a member of our Remuneration and Nomination
Committee. Our board of directors has determined that Ms. Verplancke is independent under the applicable rules of the Nasdaq Stock
Market.

Our  Remuneration  and  Nomination  Committee  assists  our  board  of  directors  in  its  decisions  relating  to  the  remuneration  policy  and
individual  remuneration  packages  for  our  board  of  directors,  the  appointment  of  directors,  the  Chief  Executive  Officer  and  the  other
members of senior management.

The Remuneration and Nomination Committee’s duties and responsibilities to carry out its purposes include, among others:

● identifying  individuals  qualified  to  become  members  of  our  board  of  directors,  consistent  with  criteria  approved  by  our

board of directors;

● recommending to our board of directors the director nominees for each annual general meeting, taking into account any

nomination rights that certain shareholders may have under our restated articles of association;

● recommending to our board of directors director nominees to fill vacancies;

● recommending to our board of directors qualified and experienced directors for service on the committees of the board of

directors;

● recommending to our board of directors the compensation of the members of senior management;

● recommending to our board of directors any incentive compensation plans and equity-based plans, and awards thereunder,

and profit-sharing plans for our employees;

● evaluating the performance of our Chief Executive Officer; and

● advising our board of directors on other compensation issues.

have never experienced a work stoppage.

(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 26, 2024, including through the exercise of any option, warrant or other right or the conversion

Except as otherwise indicated, we believe the persons named in this table have sole voting and investment power with respect to all
ordinary shares shown as beneficially owned by them, subject to community property laws where applicable and to the information
contained in the footnotes to this table.

(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 2,171,497 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.

As  of  March  26,  2024,  there  were  30  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 26, 2024, 53.60% of our outstanding ordinary shares were held directly by 30 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 26, 2024, 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,  2023,  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 2023, we incurred K€97 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.

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.

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.

In May 2023, the Belgian Center for Arbitration and Mediation issued a decision in the arbitration proceedings filed by Zimmer Biomet
against Materialise, pursuant to which we were ordered to pay an amount of € 5,0000,000 plus interest to Zimmer Biomet. No amounts
had been accrued for this loss contingency.

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.

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.

bonds held by Peter Leys and his spouse by € 1,000,000 against the issuance of 508,904 new ordinary shares.

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.

On June 9, 2021, the board of directors decided to increase the share capital of Materialise NV, which capital increase was confirmed on
June 14, 2021 and July 6, 2021, by € 320.000,00 (excluding an issuance premium of € 78.484.793,95) and € 48.000,00 (excluding an
issuance premium of € 11.772.719,09), respectively, against the issuance of 4,000,000 and 600,000 new ordinary shares, respectively.

On  November  23,  2021,  the  board  of  directors  increased  the  share  capital  of  Materialise  NV  following  the  exercise  of  warrants
previously  issued  under  the  2014  Warrant  Plan  and  the  2015  Warrant  Plan  by  €  13.655,81  (excluding  an  issuance  premium  of
1.570.065,03)  and  €  8.595,46  (excluding  an  issuance  premium  of  €  721.222,04)  against  the  issuance  of  179.764  and  113.150  new
ordinary shares, respectively.

On  December  28,  2022,  the  board  of  directors  increased  the  share  capital  of  Materialise  NV  following  the  exercise  of  warrants
previously issued under the 2014 Warrant Plan and the 2015 Warrant Plan by € 65,71 (excluding an issuance premium of 7,554.94) and €
212.70 (excluding an issuance premium of € 17.847,30) against the issuance of 865 and 2,800 new ordinary shares, respectively.

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.

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  paid-up  capital  made  in  accordance  with  the  Belgian  Code  of  Companies  and
Associations is in principle partly considered to be a dividend distribution from a Belgian tax perspective 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
paid-up  capital  on  the  other  hand.  In  principle,  fiscal  paid-up  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
paid-up  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 paid-up 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 attributed. U.S. holders should consult their own tax advisors in
Belgium  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.

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.”

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 for ordinary shares 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.

Table of Contents

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. A 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.

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, etc. 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  (non-exhaustive  list):  (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. In June 2023, the European Commission stated that “the prospects of reaching an agreement on the FTT in the future
are  limited  given  that  the  last  substantial  discussions  took  place  under  the  Portuguese  Council  Presidency  in  2021”  adding  there  was
“little expectation that any proposal would be agreed in the short term.”

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.

95

Table of Contents

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.

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.

Passive Foreign Investment Company

We believe that we were not a PFIC for the tax year ended December 31, 2023, 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, 2024, 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, 2023 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.

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.

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.

99

Table of Contents

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, 2023, 2022 and 2021, 34%, 39%, 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 € 0.8 million lower, excluding the effect of the cash and term accounts held in U.S. dollars.

To limit the exposure to foreign currency rate fluctuations on the U.S. dollar, we have entered into currency rate swaps. As of December
31, 2023, we had hedge agreements in place for $ 11.2 million, all maturing before year-end 2024. Refer to note 20 to our consolidated
financial statements for the related fair value of these derivatives.

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 fluctuating inflation. The risk exists that, if inflation increases our
costs of remuneration, materials, services, energy, and capital expenditures, we may not be able to offset such costs fully by increasing
our  selling  prices.  As  such,  in  a  high  inflationary  environment,  our  results  of  operations  and  financial  condition  may  be  adversely
affected.

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,  2023,  we  had  cash  and  cash  equivalents  of  €  127.6
million, while € 25.5 million of our € 64.4 million gross debt was short term. At December 31, 2023, 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, 2023, 2022 and 2021.

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

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.

ITEM 15. 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, 2023. 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, 2023, 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,  2023  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”).

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, 2023.

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.

● 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.

105

Table of Contents

● 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.

CYBERSECURITY

Our board of directors recognizes the critical importance of maintaining the trust and confidence of our customers, clients, shareholders,
business partners, and employees. While everyone at Materialise plays a part in managing our cybersecurity risk management strategy,
primary cybersecurity oversight responsibility is shared by our board of directors, and members of our senior management as part of our
Executive  Committee,  as  supported  by  our  Governance  Bureau.  The  Executive  Committee  is  actively  involved  in  oversight  of  the
Materialise  risk  management  program  and  supports  our  board  of  directors  in  the  development  and  continual  improvement  of  our
information  security  management  system.  Our  cybersecurity  policies,  standards,  processes,  and  practices  are  fully  integrated  into  our
operational  processes  and  are  based  on  recognized  frameworks  established  by  the  International  Organization  for  Standardization
(including ISO 27001 and 27701) and other applicable industry standards (including TISAX). We address cybersecurity risks through a
comprehensive, cross-functional approach that is focused on safeguarding the confidentiality, integrity, and availability of our products
and services, our customers’ and our own data, and our supporting IT infrastructure. We apply the principle of “defense in depth” and
focus both on preventing the occurrence of cybersecurity incidents, and providing an effective response to cybersecurity incidents when
they do occur.

Risk Management and Strategy

As one of the critical elements of our overall corporate risk management approach, the information security program is focused on the
following key areas:

● Governance:  As  discussed  in  more  detail  under  the  heading  “Governance,”  our  board  of  directors’  oversight  of
cybersecurity risk management is supported by our Executive Committee which consists of eight members.The Executive
Committee is also supported by our Governance Bureau, which consists of our Chief Executive Officer, Chief Operating
Officer, and the Director of Internal Audit, and regularly invites the Chief Information Security Officer and other members
executive management to closely follow up on open cybersecurity risks.

● Defense  in  depth:  We  have  implemented  a  comprehensive,  cross-functional  approach  to  identifying,  preventing,  and
mitigating cybersecurity threats and incidents, while also implementing controls and procedures that provide for the prompt
escalation  of  certain  cybersecurity  incidents  so  that  decisions  regarding  the  public  disclosure  and  reporting  of  such
incidents can be made by management in a timely manner.

● Technical Safeguards:  We  deploy  technical  safeguards  that  are  designed  to  protect  our  information  systems  and  online
environments  from  cybersecurity  threats,  including  firewalls,  intrusion  prevention  and  detection  systems,  anti-malware
functionality and access controls, which are evaluated and improved through vulnerability assessments and cybersecurity
threat intelligence.

● Incident  Response  and  Recovery  Planning:  We  have  established  and  we  maintain  incident  response  procedures  and
recovery plans to ensure our ability to timely respond to and recover from a cybersecurity incident. These procedures and
plans are tested and evaluated on a regular basis. Cybersecurity incidents are assessed and handled according to risk-based
priority levels.

● Third  Party  Risk  Management:  We  maintain  a  comprehensive  risk-based  approach  to  identifying  and  overseeing
cybersecurity  risks  presented  by  third  parties,  including  vendors,  service  providers,  and  third-party  systems  that  could
adversely impact our business in the event of a cybersecurity incident affecting those third-party systems.

● Education  and  Awareness:  Materialise  provides  continual  training  and  awareness  for  personnel  regarding  cybersecurity
threats to equip personnel with effective tools to address those threats, and to communicate evolving information security
policies, standards, processes, and practices.

107

Table of Contents

We  engage  in  the  periodic  assessment  and  testing  of  policies,  implemented  standards,  processes,  and  practices  that  are  designed  to
address  cybersecurity  threats  and  incidents.  These  efforts  include  a  wide  range  of  activities,  including  internal  audits,  assessments,
vulnerability  scanning,  security  testing  and  disaster  recovery  exercises  focused  on  evaluating  the  effectiveness  of  our  cybersecurity
measures  and  planning.  We  regularly  engage  third  parties  to  perform  assessments  on  our  cybersecurity  measures,  including  phishing
simulations,  security  penetration  testing,  and  external  compliance  audits.  The  results  of  such  assessments,  audits,  and  reviews  are
handled  according  to  our  internal  nonconformity  and  risk  management  processes  and  reported  to  the  Executive  Committee  or
Governance Bureau. We continually improve our cybersecurity policies, standards, processes, and practices as necessary based on the
information provided by these assessments, audits, and reviews.

Governance

The  Executive  Committee,  in  coordination  with  the  Governance  Bureau,  oversees  the  corporate  management  system,  which  includes
information  security  management.  Twice  a  year,  the  Executive  Committee  receives  an  update  from  the  relevant  members  of  senior
management  as  part  of  the  corporate  management  review,  including  recent  developments  of  relevant  cybersecurity  risks,  evolving
standards,  the  threat  environment,  technological  trends  and  information  security  considerations  arising  with  respect  to  Materialise’s
customers and peers. The Governance Bureau also receives prompt and timely information regarding any rapidly evolving cybersecurity
risks or incidents that meet established reporting thresholds, as well as ongoing updates regarding any such topics until they have been
addressed. The Executive Committee, provides updates to the board of directors with respect to cybersecurity risks, which address a wide
range of topics, including recent developments, evolving standards, vulnerability assessments, third-party and independent reviews, the
threat environment, technological trends and information security considerations arising with respect to the Company’s peers and third
parties. Further, on an annual basis, the corporate information security roadmap is updated to account for the evolving threat landscape
and strategic cybersecurity priorities for Materialise and its customers and presented to the Governance Bureau for approval.

Moreover, the CISO, in coordination with the Governance Bureau and Executive Committee, works collaboratively across the company
to implement a program designed to protect Materialise’s information systems from cybersecurity threats and to promptly respond to any
cybersecurity  incidents  in  accordance  with  established  incident  response  and  recovery  plans.  Through  ongoing  communications  with
these teams, the CISO monitors the prevention, detection, mitigation, and remediation of cybersecurity threats and incidents, and reports
such threats and incidents to the Governance Bureau when appropriate.

The  CISO  has  served  in  various  roles  in  product  security  and  information  security  management  for  over  15  years.  The  CISO  holds
undergraduate and graduate degrees in computer science and has a Ph.D. in secure software engineering.

Although we are subject to ongoing and evolving cybersecurity threats, we are not aware of any material risks from cybersecurity threats
in 2023, including as a result of any previous cybersecurity incidents, that have materially affected or are reasonably likely to affect us,
including our business strategy, results of operations or financial condition. If we were to experience a material cybersecurity incident in
the future, such incident may have a material effect, including on our business strategy, operating results, or financial condition. For more
information  regarding  cybersecurity  risks  that  we  face  and  potential  impacts  on  our  business  related  thereto,  see  the  risk  factors
disclosures in Item 3 of this Annual Report on Form 20-F titled “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”, “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”  and  “We  develop  and  offer  online  software  services  through  our  SaaS  and  cloud-based
software applications where we manage data we receive from our customers, and a cybersecurity breach of these online services could
harm  our  customers  and  our  reputation,  expose  us  to  liability,  and  adversely  impact  our  business,  financial  condition  and  results  of
operations.”

Report of Independent Registered Public Accounting Firm

To the Shareholders and Board of Directors

Materialise NV:

Opinions on the Consolidated Financial Statements and Internal Control Over Financial Reporting

We have audited the accompanying consolidated statements of financial position of Materialise NV and subsidiaries (the Company) as of
December  31,  2023,  2022  and  2021,  the  related  consolidated  income  statements,  consolidated  statements  of  comprehensive  income,
consolidated statements of changes in equity, and consolidated cash flow statements for each of the years in the three-year period ended
December  31,  2023  and  the  related  notes  (collectively,  the  consolidated  financial  statements).  We  also  have  audited  the  Company’s
internal  control  over  financial  reporting  as  of  December  31,  2023,  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, 2023, 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,  2023,  in  conformity  with  IFRS  Accounting  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, 2023 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.

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.

F-2

Table of Contents

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 Matter

The critical audit matter communicated below is a matter arising from the current period audit of the consolidated financial statements
that was communicated or required to be communicated to the audit committee and that: (1) relates 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  the  critical  audit  matter  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 matter below, providing a separate opinion on the critical audit matter or on
the accounts or disclosures to which it relates.

Impairment analysis for the Engimplan and the Materialise Motion cash generating units

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 amounts of the Engimplan and the Materialise Motion CGUs based on the value in use using a
discounted cash flow model. As discussed in Note 5 to the consolidated financial statements, the Company recorded an impairment of
K€ 657 related to the Engimplan CGU and K€ 3,572 related to the Materialise Motion CGU at December 31, 2023.

We identified the evaluation of the impairment analysis for the Engimplan and the Materialise Motion CGUs as a critical audit matter. A
high degree of subjective auditor judgment and specialized skills and knowledge was required to evaluate the Engimplan and Materialise
Motion CGUs’ respective forecasted year-on-year growth rate of revenue and gross margin, the perpetual growth rate and the discount
rate, as changes in these assumptions could cause significant changes in the value in use of the Engimplan and Materialise Motion CGUs.

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  forecasted  year-on-year  growth  rate  of  revenue  and  gross
margin, the perpetual growth rate and the discount rate used to determine the value in use of the Engimplan and Materialise
Motion CGUs.

— We  evaluated  the  forecasted  year-on-year  growth  rates  of  revenue  and  gross  margins  by  comparing  them  to  the  CGUs’

historical performances.

— We assessed management’s ability to accurately forecast by comparing forecasts made by management in the prior year to

the actual performances of the Engimplan and Materialise Motion CGUs.

— We also involved valuation professionals with specialized skills and knowledge, who assisted in:

● evaluating  the  Company’s  discount  rates,  by  comparing  them  against  discount  rate  ranges  that  were  independently

developed using publicly available market data for comparable entities; and

● evaluating the Company’s perpetual growth rates, by comparing them against the CGUs’ historical performances and

to external market and industry data.

Basis of preparation

The  consolidated  financial  statements  of  the  Group  for  the  three  years  ended  December  31,  2023,  2022  and  2021  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 which 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  2023,  but  do  not  have  a

Standards and Interpretations issued but not yet effective in the current period

No amendments to standards that are issued but not yet effective are considered to materially affect the Company’s accounting policies or
any of the disclosures when applied for the first time. The Company has not early adopted any of the below.

Amendments  to  IAS  1  ‘Presentation  of  Financial  Statements:  Classification  of  Liabilities  as  current  or  non-current’  (effective
January  1,  2024),  affect  only  the  presentation  of  liabilities  in  the  statement  of  financial  position  —  not  the  amount  or  timing  of
recognition of any asset, liability income or expenses, or the information that entities disclose about those items.

The amendments:

● clarify that the classification of liabilities as current or non-current should be based on rights that are in existence at the end
of the reporting period and align the wording in all affected paragraphs to refer to the “right” to defer settlement by at least
twelve  months  and  make  explicit  that  only  rights  in  place  “at  the  end  of  the  reporting  period”  should  affect  the
classification of a liability;

● clarify that classification is unaffected by expectations about whether an entity will exercise its right to defer settlement of
a liability; and make clear that settlement refers to the transfer to the counterparty of cash, equity instruments, other assets
or services; and

● clarify how conditions with which an entity must comply within 12 months after the reporting period, such as covenants,

affect the corresponding liability’s classification.

Amendments to IFRS 16 Leases: Lease Liability in a Sale and Leaseback (effective January 1, 2024). The amendments explain how
an entity accounts for a sale and leaseback after the date of the transaction, specifically where some or all the lease payments are variable
lease  payments  that  do  not  depend  on  an  index  or  rate.  They  state  that,  in  subsequently  measuring  the  lease  liability,  the  seller-lessee
determines ‘lease payments’ and ‘revised lease payments’ in a way that does not result in the seller-lessee recognizing any amount of the
gain or loss that relates to the right of use it retains. Any gains and losses relating to the full or partial termination of a lease continue to
be recognized when they occur as these relate to the right of use terminated and not the right of use retained.

Amendments  to  IAS  7  ‘Statement  of  Cash  Flows’  and  IFRS  7  ‘Financial  Instruments:  Disclosures’1:  Supplier  Finance
Arrangements  (effective  1  January  2024).  The  amendments  add  disclosure  requirements,  and  ‘signposts’  within  existing  disclosure
requirements, that ask entities to provide qualitative and quantitative information about supplier finance arrangements.

The amendments:

● Do not define supplier finance arrangements.

● Add  two  disclosure  objectives.  Entities  will  have  to  disclose  in  the  notes  information  that  enables  users  of  financial
statements to assess how supplier finance arrangements affect an entity’s liabilities and cash flows and to understand the
effect of supplier finance arrangements on an entity’s exposure to liquidity risk and how the entity might be affected if the
arrangements were no longer available to it.

● Complement current requirements in IFRSs by adding to IAS 7 additional disclosure requirements about the type and effect
of non-cash changes in the carrying amounts of the financial liabilities that are part of the arrangement and the terms and
conditions of the supplier finance arrangements; for the arrangements, as at the beginning and end of the reporting period:

o

o

o

the carrying amounts of financial liabilities that are part of the arrangement and the associated line item presented;

the carrying amount of financial liabilities disclosed under a) for which suppliers have already received payment
from the finance providers;

the range of payment due dates (for example, 30 to 40 days after the invoice date) of financial liabilities disclosed
under a) and comparable trade payables that are not part of a supplier finance arrangement.

Amendments  to  IAS  21  ‘The  Effects  of  Changes  in  Foreign  Exchange  Rates:  Lack  of  Exchangeability’1,  (effective  1  January
2025).  The  amendments  to  IAS  21  The  Effects  of  Changes  in  Foreign  Exchange  Rates  require  disclosure  of  information  that  enables
users of financial statements to understand the impact of a currency not being exchangeable.

The amendments:

● Specify when a currency is exchangeable into another currency and when it is not.

● Specify how an entity determines the exchange rate to apply when a currency is not exchangeable.

● Require the disclosure of additional information when a currency is not exchangeable.

3 Material 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.

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”.

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.

Acquisition costs incurred are expensed and included in general and administrative expenses.

F-13

Table of Contents

Property, plant & equipment

Property, plant and equipment is stated at cost, net of accumulated depreciation and/or accumulated impairment losses, if any. 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

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 Group recognizes right-of-use assets at the commencement date of the lease (i.e., the date the underlying asset is available for use).
Unless the Group 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 review whenever there is an indication that the right-of-use asset may be impaired.

Lease liabilities:

In calculating the present value of lease payments, the Group uses the incremental borrowing rate at the lease commencement date. 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-14

 
Table of Contents

Short-term leases and leases of low-value assets:

The Group 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.

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-15

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:

    3 years;
10 years;
subscription term
10 years;
5-20 years;

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, 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  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. An impairment loss recognized for goodwill is not reversed.

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.

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.

F-16

 
Table of Contents

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 and Essentium, 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.

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;

● a convertible loan granted to the company Fluidda as disclosed in Note 10.

F-17

Table of Contents

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.

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.

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.

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.

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.

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.

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.

F-18

Table of Contents

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.

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.

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.

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.

Revenue from contracts with customers is recognized when control of the goods or services is 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.

F-19

Table of Contents

Most of the perpetual software licenses include one year maintenance and support services as a separate performance obligation. The
Group 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 Group 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.

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  Group  determines  the  percentage-of-completion  by  comparing  labor  hours  incurred  to-date  to  the  estimated  total  labor  hours
required to complete the project. The Group considers labor hours to be the most reliable available measure of progress on these projects.
Adjustments to the Group’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.

F-20

Table of Contents

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 Group 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.

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.

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 Group 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.

F-21

Table of Contents

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.

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 (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.

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-22

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

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.

F-23

Table of Contents

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€1,577 of development expenses during 2023 (2022: K€2,438; 2021: K€1,684) related to capitalized
internal development of our digital transformation program for which a detailed business plan is available and the Group expects future
economic benefits.

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, 2023, the Group had current and non-current receivables related to tax credits for an amount of K€5,281 (2022: K€5,105;
2021: K€4,717).

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.

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€43,158 as of December 31, 2023 (2022: K€44,155; 2021: K€18,726) 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.

During 2023 impairment charges have been recorded for K€4,228 (2022: K€672; 2021: K€177) related to the impairment of goodwill,
intangible assets and PPE of Materialise Motion and Engimplan.

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.

F-24

Table of Contents

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.

Convertible debt instruments

At December 31, 2023 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, 2023 amounted to K€3,744. 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 13.32% 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. Despite a fundamental restructuring program implemented in 2023,
AM Flow continues to be loss making, with no outlook on quick turnaround. Additional fund-raising and external debt were required in
2023 to avoid acute liquidity issues. 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,  2023  and  recognized  a  K€307  downward  fair  value
adjustment in OCI for the year ended December 31, 2023.

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.  As  a  result  of  liquidity  issues  at
Essentium 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. The
Group determined that the fair value of this equity investment remained zero at December 31, 2022. Early January 2024 the company
entered  into  an  asset  deal  with  Nexa3D,  Inc.  transferring  virtually  all  of  its  assets  in  exchange  for  a  stake  in  the  common  stock  of
Nexa3D, Inc. Taking into account the terms and conditions of this transaction, the Group determined that the fair value of this equity
investment remained nevertheless zero at December 31, 2023.

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.

F-25

Table of Contents

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.

Business Combinations

Acquisitions in 2023

The Group did not effect any business combinations in the course of 2023.

Acquisitions in 2022

Materialise Link3D, Inc.

On April 9, 2021, the Group acquired an option to buy Link3D, Inc. (“Link3D”) 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. Link3D is an
additive workflow and digital manufacturing software company. The Group acquired 100% of voting equity interests in Link3D 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  fair  value  of  the  identified  assets  and  liabilities  included  in  our  consolidated  financial  statements  at  the  acquisition  date  was
K€3,496. 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.  As
integration within the Materialise Software segments started immediately it is impracticable to disclose information on profit.

There are no contingent considerations payable.

Materialise Identify3D, Inc.

On  September  1,  2022,  the  Group  executed  a  share  purchase  agreement  and  acquired  100%  of  the  shares  of  Identify3D,  Inc.
(“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.

The  fair  value  of  the  identified  assets  and  liabilities  included  in  our  consolidated  financial  statements  at  the  acquisition  date  was
K€1,413. The Group acquired 100% of voting equity interests in ID3D Inc. for a total consideration of K€3,853. This is the fair value of
the identified assets and liabilities increased by a goodwill of K€2,439.

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

The accounting for the business combination resulted in fair values at date of acquisition of K€174 for Brands and trademarks (useful life
of  7  years)  and  K€1,723  for  software  (useful  life  of  7  years).  The  valuation  technique  used  to  measure  the  fair  value  of  brands  and

royalty  rate,  the  brands  and  trademarks  royalty  rate  and  the  discount  rate.  A  deferred  tax  liability  was  recognized  of  K€(474)  on  the
adjusted fair values. The discount rate used for the valuation was set at 14.05%. Trade receivables acquired comprised gross contractual
amounts due of K€0.

date of December 31, 2022 was K€ 0. As integration within the Materialise Software segments started immediately it is impracticable to
disclose information on profit.

There are no contingent considerations payable.

The goodwill of MAT Software, Orthoview and e-Prototypy include respectively K€28, K€93 and K€57 impact of currency translation in
2023.

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), 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  9.91%  (11.21%  pre-tax)  (2022:
9.67% post-tax; 2021: 7.40% post-tax) and a perpetual growth rate of 5% (2022: 5%; 2021: 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€41,158. 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 12.89%
(14.89%  pre-tax)  (2022:  12.72%  post-tax;  2021:  9.90%  post-tax)  and  a  perpetual  growth  rate  of  2%  (2022:  2%;  2021:  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 higher than the carrying value of the cash generating unit of K€4,144. 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 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 8.26% (11.33% pre-tax) (2022: 8.04% post-tax; 2021: 6.36% post-tax) and a
perpetual growth rate of 1% (2022: 1%; 2021: 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€24,824.  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  10.75%  (13.69%  pre-tax)  (2022:
10.27% post-tax; 2021: 8.05% post-tax) and a perpetual growth rate of 1% (2022: 1%; 2021: 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€12,307. 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 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 18.82% (21.26% pre-tax) (2022: 19.84% post-tax; 2021: 15.49% post-tax) and
a perpetual growth rate of 7.6% (2022: 8.5%; 2021: 7.0%), supported by an expected long term inflation rate of 4.1%, 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.  It  was  concluded  that  the  value  in  use  is  lower  than  the  carrying  value  of  the  cash  generating  unit  of  K€9,214  which  has
resulted in a full impairment of the intangible assets customer lists and trade marks for respectively K€(397) and K€(121) as well as a
tangible asset 3D printer for K€(139) as shown in Note 6 and Note 7. The full impairment charge was recognized in the Consolidated
income statement under Net other operating income and is included in the reportable segment ‘Materialise Medical’.

The key events that led to the impairment loss for the CGU Engimplan were related to a delay of business growth and to less advantage
of synergies than initially foreseen.

A sensitivity analysis was performed to assess the impact of changes in the key assumptions used on the current estimated value-in-use
and can be summarized as follows:

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 9.91% (11.72% pre-tax) (2022: 9.67% post-tax; 2021: 7.40% post-tax) and a
perpetual growth rate of 3% (2022: 5%; 2021: 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
lower  than  the  carrying  value  of  the  cash  generating  unit  of  K€3,605  which  has  resulted  in  a  full  impairment  of  the  goodwill  for  an
amount of K€(1,175) as well as a partial impairment on intangible assets partnership agreement, customer list, and developed technology
for respectively K€(853), K€(107), and K€(1,437) as shown in Note 6. The full impairment charge was recognized in the Consolidated
income statement under Net other operating income and is included in the reportable segment ‘Materialise Manufacturing’.

The key event that led to the impairment loss for the CGU Materialise Motion was a delay in business growth versus what was initially
foreseen.

The Group’s share-based payment plans are all equity-settled except for the IPO warrants that have been granted to certain employees in
certain countries due to legal requirements which are cash-settled. The outstanding amount includes stock appreciation rights (“SARs”)
issued under cash-settled share-based payment plans.

In all outstanding warrant plans one warrant gives right to one share.

Equity-settled share-based payment plans

The Group has several plans in place which each have slightly different characteristics as described below.

IPO warrant plan

Each warrant gives the right to the holder to one ordinary share of the parent Company. The warrants have a contractual term of 10 years
and vested for 25% in the fourth year; 25% in the fifth year; 25% in the sixth year and 25% in the seventh year. Warrants are exercisable
as from the month after they have vested and in the subsequent exercise periods. There are no cash settlement alternatives and the Group
does not have a practice of cash settlement for these warrants. The warrants have a contractual term of 10 years.

The Group granted 979,898 warrants in July 2014 and 36,151 warrants in November 2014 in the context of the initial public offering to
the employees of the Group with an exercise price of €8.81 (“IPO warrant plan”). The Group granted an additional 18,180 warrants to

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 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

● 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€47 in 2023 (2022: K€0; 2021:
K€41).

The weighted average fair value for the warrants outstanding at the end of 2023 was €3.19 (2022: €3.41; 2021: €3.39). The weighted
average exercise price for the warrants outstanding at the end of 2023 was €5.39 (2022: €8.12; 2021: €8.07).

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 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 vested 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.

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,  2023,  The  Group  was  in
compliance with all debt covenants.

The fair value of the financial assets has been determined on the basis of the following methods and assumptions:

● the  carrying  value  of  the  cash  and  cash  equivalents  and  the  current  receivables  approximate  their  fair  value  due  to  their

short term character;

● 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);

● other current non-trade receivables are being evaluated on the basis of their credit risk and interest rate. Their fair value is

not different from their carrying value on December 31, 2023, 2022 and 2021

● 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.

● for the non-listed equity investment in AM Flow, as of December 31, 2023, Materialise recorded a remeasurement of fair

value to zero through OCI (K€307).

● 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, 2023, management determined the

fair value based upon level 3 inputs as follows:

o The Group determined that the fair value of the convertible loan as of December 31, 2023 amounted to K€3,802.
Fluidda is a private start-up company which offers turnkey contract research services for drug development and
medical device development. 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  13.32%  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.

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  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€(51) / K€52. As the carrying value is not materially different from the fair value, the Group has
not made an adjustment to the carrying value.

Financial liabilities:

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). We refer to Note 14.

Fair value hierarchy

The Group uses the following hierarchy for determining and disclosing the fair value of financial instruments by valuation technique:

● Level 1: quoted (unadjusted) prices in active markets for identical assets and liabilities;

● Level  2:  other  techniques  for  which  all  inputs  which  have  a  significant  effect  on  the  recorded  fair  value  are  observable,

either directly or indirectly; and

● Level  3:  techniques  which  use  inputs  that  have  a  significant  effect  on  the  recorded  fair  value  that  are  not  based  on

observable market data.

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.

We refer to Note 18 for a detail of the deferred income. 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 2023 that was included in the contract liability at the beginning of the year amounts
to K€41,721.

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.

Basic earnings per share amounts are calculated by dividing the net profit (loss) for the year attributable to ordinary equity holders of the
parent company by the weighted average number of ordinary shares outstanding during the year.

Diluted  earnings  per  share  amounts  are  calculated  by  dividing  the  net  profit  (loss)  attributable  to  ordinary  equity  holder  of  the  parent
company by the weighted average number of ordinary shares outstanding during the year plus the weighted average number of ordinary
shares that would be issued on conversion of all warrants and the weighted average number of ordinary shares that would be issued on
conversion of the convertible debt. If there is a net loss after taxes, the number of diluted shares is equal to the basic shares.

The net profit (loss) for the year used for the basic and diluted earnings per share are reconciled as follows:

The Group has several loans secured by a mortgage on the building. The carrying value of related property, plant & equipment (including
buildings  under  construction)  is  K€22,165  (2022:  K€23,560;  2021:  K€25,582).  The  total  outstanding  mortgages  and  pledges  are
K€100,755 in 2023 (2022: K€100,978; 2021: K€103,685).

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  2023  (2022:  K€69,300;  2021:  K€69,300)  and  pledges  on  other  fixed  assets  for  a  total  amount  of  K€219  (2022:  K€442;
2021: K€1,399).

Other commitments

At December 31, 2023, the Group has outstanding non-cancellable contracts with a future commitment of K€22,267 (2022:K€25,385;
2021:K€7,043),  mainly  related  to  purchase  commitment  for  raw  materials,  energy  and  gas;  and  of  K€9,330  (2022:  K€0;  2021:  K€0)
related to property, plant & equipment.

Legal Proceedings

The Group is currently not a party to any 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

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,  2023,  2022  and  2021,  34%,  39%  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.

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 € 0.8 million lower, excluding the effect of the cash and term accounts held in U.S. dollars.

To  limit  the  exposure  to  foreign  currency  rate  fluctuations  on  the  U.S.  dollar,  the  Group  has  entered  into  currency  rate  swaps.  As  of
December 31, 2023 the Group had hedge agreements in place for $ 11.2 million, all maturing before year-end 2024. 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 increases our
costs of remuneration, materials, services, energy, and capital expenditures, we may not be able to offset such costs fully by increasing
our  selling  prices.  As  such,  in  a  high  inflationary  environment,  our  results  of  operations  and  financial  condition  may  be  adversely
affected.

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,  2023,  we  held  cash  and  cash
equivalents of € 127.6 million, while €25.5 million of our € 64.4 million gross debt was short term. At December 31, 2023, we had an
undrawn credit line of € 50 million as more fully described in Note 15 to the consolidated financial statements.

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.

Set out below is the information about the credit risk exposure on the Group’s trade receivables using a provision matrix:

The primary objective of the Group’s shareholders’ capital management strategy is to ensure it maintains healthy capital ratios to support
its business and maximize shareholder value. 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

EBITDA and Adjusted EBITDA is used in the Note 21 Segments as one of the basis of the Segments performance measurement. We
calculate EBITDA as net profit plus income taxes, financial expenses (less financial income), depreciation and amortization, and share in
loss of joint venture. Adjusted EBITDA is determined by adding back share-based compensation expenses, acquisition-related expenses
of business combinations, impairments and fair value remeasurements due to business combinations to EBITDA.

Irrespective the moment within the Exercise Period on which the aforementioned actions have been taken, the Subscription Rights will be deemed to
have been exercised on the last date of this Exercise Period.

Upon (and under condition of) acceptance of the Subscription rights, the Selected Participant shall also grant a call option in favour of the Company on
all the shares they have acquired following the exercise of the Subscription rights.

This call option shall be exercisable for six months after the end of the Employment Agreement, the Consultant Agreement, or the Directorship (or, if
later, within six months from the exercise of the Subscription rights taking place after the end of the Employment Agreement, the Consultant
Agreement, or the Directorship of the relevant Selected Participant), and may be applied to the whole or a part of the ordinary shares acquired by the
Selected Participant (or Beneficiary) following the exercise of the Subscription rights. The price per share upon which the call option may be exercised
shall be determined as follows:

4.12.

Costs and Taxes

Stamp duties, brokerage fees and other similar duties or taxes or social securitiy contributions levied as a result of the Offer, the Grant, the Exercise or
the Transfer of the Subscription Rights and / or the acquisition of ordinary shares or ADSs shall be borne by the Subscription Rights Holder.

4.13.

Changes to the capital structure of the Company - reservation of rights

Notwithstanding Article 7:71 of the Code on Companies and Associations and without prejudice to the statutory exceptions, the Company may take any
decisions it deems necessary with respect to its capital, its Articles of Association or its management, including, but not limited to, a capital reduction
with or without distribution to shareholders, a capital increase by incorporation of reserves whether or not new shares are created, a capital increase by
contributions in kind, a capital increase by cash contribution whereby the preferential right of the existing shareholders may or may not be restricted or
withdrawn, an issue of bonus shares, convertible bonds, preferred shares, bonds cum subscription rights, ordinary bonds or naked subscription rights, an
alteration to the Articles of Association regarding the appropriation of profit or the liquidation proceeds or other rights attached to the ordinary shares, a
share split, a distribution of share dividends, a dissolution of the Company, a merger, a division or a contribution or a transfer of a totality or of an
industry whether or not accompanied by the exchange of shares. The Company may make such resolutions even if they (could) lead to a reduction of the
benefits which the issuance conditions of the Subscription Rights and the law assign to the Subscription Rights Holders, unless the sole purpose of such
resolutions should be such a reduction.

 In the event of a merger or division, the Board of Directors shall make all reasonable efforts to ensure that the Subscription Rights outstanding at the 
date of such transaction shall be replaced by subscription rights in the merged company or the demerged companies in accordance with the exchange 
ratio applied to the ordinary shares of the Company existing at that time.

4.14.

Exercise of the Subscription Rights in accordance with the law

If the Subscription Rights Holder exercises Subscription Rights under Article 7:71 of the Code on Companies and Associations, the thus acquired
ordinary shares shall not be transferable as long as the Subscription Rights would not have been otherwise (i.e. abstraction of such exercise) exercisable
in accordance with the issuance and exercise conditions. The possible tax consequences of such exercise shall be borne by the Subscription Rights
Holder.

5.

COMPENSATION RECOVERY POLICY

EXHIBIT 97.1

The Board has determined that it is in the best interests of the Company and its shareholders to adopt this Policy
enabling the Company to recover from specified current and former Company executives certain incentive-based
compensation in the event of an accounting restatement resulting from material noncompliance with any financial
reporting requirements under the federal securities laws.  Capitalized terms are defined in Section 14.

This  Policy  is  designed  to  comply  with  Rule  10D-1  of  the  Exchange  Act  and  shall  become  effective  on  the
Effective  Date  and  shall  apply  to  Incentive-Based  Compensation  Received  by  Covered  Persons  on  or  after  the
Listing Rule Effective Date.

1.

Administration

This Policy shall be administered by the Administrator. The Administrator is authorized to interpret and construe
this  Policy  and  to  make  all  determinations  necessary,  appropriate,  or  advisable  for  the  administration  of  this
Policy.  The Administrator may retain, at the Company’s expense, outside legal counsel and such compensation,
tax or other consultants as it may determine are advisable for purposes of administering this Policy.

2.

Covered Persons and Applicable Compensation

This Policy applies to any Incentive-Based Compensation Received by a person (a) after beginning service as a
Covered  Person;  (b)  who  served  as  a  Covered  Person  at  any  time  during  the  performance  period  for  that
Incentive-Based Compensation; and (c) was a Covered Person during the Clawback Period.

However, recovery is not required with respect to:

i.

Incentive-Based  Compensation  Received  prior  to  an  individual  becoming  a  Covered  Person,  even  if  the
individual served as a Covered Person during the Clawback Period.

ii.

Incentive-Based Compensation Received prior to the Listing Rule Effective Date.

iii. Incentive-Based Compensation Received prior to the Clawback Period.

iv. Incentive-Based Compensation Received while the Company did not have a class of listed securities on a
national  securities  exchange  or  a  national  securities  association  in  the  United  States,  including  the
Exchange.

The Administrator will not consider the Covered Person’s responsibility or fault or lack thereof in enforcing this
Policy with respect to recoupment under the Final Rules.

3.

Triggering Event

Subject to and in accordance with the provisions of this Policy, if there is a Triggering Event, the Administrator
shall require a Covered Person to reimburse or forfeit to the Company the Recoupment Amount applicable to such
Covered Person.  A Company’s obligation to recover the Recoupment Amount is not dependent on if or when the
restated financial statements are filed.

4.

Calculation of Recoupment Amount

The Recoupment Amount will be calculated in accordance with the Final Rules, as provided in the Calculation
Guidelines attached hereto as Exhibit B.

5.

Method of Recoupment

Subject  to  compliance  with  the  Final  Rules  and  applicable  law,  the  Administrator  will  determine,  in  its  sole
discretion, the method for recouping the Recoupment Amount hereunder which may include, without limitation:

i. Requiring  reimbursement  or  forfeiture  of  the  pre-tax  amount  of  cash  Incentive-Based  Compensation

previously paid;

ii. Offsetting  the  Recoupment  Amount  from  any  compensation  otherwise  owed  by  the  Company  to  the
Covered  Person,  including  without  limitation,  any  prior  cash  incentive  payments,  executive  retirement
benefits,  wages,  equity  grants  or  other  amounts  payable  by  the  Company  to  the  Covered  Person  in  the
future;

iii. Seeking  recovery  of  any  gain  realized  on  the  vesting,  exercise,  settlement,  cash  sale,  transfer,  or  other

disposition of any equity-based awards; and/or

iv. Taking any other remedial and recovery action permitted by law, as determined by the Administrator.

6.

Arbitration

To the fullest extent permitted by law, any disputes that may arise under this Policy or its Exhibits including any
question  regarding  its  existence,  validity,  or  termination,  shall  be  referred  to  and  finally  resolved  by  the
International Commercial Arbitration Court under the European Arbitration Chamber (Belgium, Brussels, Avenue
Louis 146) according to the Rules of this ICAC, which as a result of referring to it, is considered as part of this
clause.

The number of arbitrators shall be three.

The seat, or legal place of arbitration shall be Brussels, Belgium.

The language to be used in the arbitral proceeding shall be Dutch. The governing law of the Policy shall be the
substantial law of the USA.

The Covered Person is not restricted from filing administrative claims that may be brought before any government
agency where, as a matter of law, the Covered Person’s ability to file such claims may not be restricted. However,
to  the  fullest  extent  permitted  by  law,  arbitration  shall  be  the  exclusive  remedy  for  the  subject  matter  of  such
administrative  claims.  If,  for  any  reason,  any  term  of  this  Arbitration  provision  is  held  to  be  invalid  or
unenforceable,  all  other  valid  terms  and  conditions  herein  shall  be  severable  in  nature  and  remain  fully
enforceable.

2

7.

Recovery Process; Impracticability

Actions by the Administrator to recover the Recoupment Amount will be reasonably prompt.

The Administrator must cause the Company to recover the Recoupment Amount unless the Administrator shall
have previously determined that recovery is impracticable and one of the following conditions is met:

i. The direct expense paid to a third party to assist in enforcing this Policy would exceed the amount to be
recovered; before concluding that it would be impracticable to recover any amount of erroneously awarded
Incentive-Based  Compensation  based  on  the  expense  of  enforcement,  the  Company  must  make  a
reasonable  attempt  to  recover  such  erroneously  awarded  Incentive-Based  Compensation,  document  such
reasonable attempt(s) to recover, and provide that documentation to the Exchange;

ii. Recovery  would  violate  home  country  law  where  that  law  was  adopted  prior  to  November  28,  2022;
before concluding that it would be impracticable to recover any amount of erroneously awarded Incentive-
Based  Compensation  based  on  violation  of  home  country  law,  the  Company  must  obtain  an  opinion  of
home  country  counsel,  acceptable  to  the  Exchange,  that  recovery  would  result  in  such  a  violation,  and
must provide such opinion to the Exchange; or

iii. Recovery would likely cause an otherwise tax-qualified retirement plan, under which benefits are broadly
available  to  employees  of  the  Company,  to  fail  to  meet  the  requirements  of  26  U.S.C.  401(a)(13)  or  26
U.S.C. 411(a) and regulations thereunder.

8.

Non-Exclusivity

The Administrator intends that this Policy will be applied to the fullest extent of the law.  Without limitation to
any  broader  or  alternate  clawback  authorized  in  any  written  document  with  a  Covered  Person,  (i)  the
Administrator may require that any employment agreement, equity award agreement, or similar agreement entered
into on or after the Effective Date shall, as a condition to the grant of any benefit thereunder, require a Covered
Person to agree to abide by the terms of this Policy, and (ii) this Policy will nonetheless apply to Incentive-Based
Compensation as required by the Final Rules, whether or not specifically referenced in those arrangements. Any
right  of  recoupment  under  this  Policy  is  in  addition  to,  and  not  in  lieu  of,  any  other  remedies  or  rights  of
recoupment  that  may  be  available  to  the  Company  pursuant  to  the  terms  of  any  other  clawback  policy  of  the
Company  as  then  in  effect,  or  any  similar  policy  in  any  employment  agreement,  equity  award  agreement,  or
similar agreement and any other legal remedies or regulations available or applicable to the Company (including
SOX 304).  If recovery is required under both SOX 304 and this Policy, any amounts recovered pursuant to SOX
304  may,  in  the  Administrator’s  discretion,  be  credited  toward  the  amount  recovered  under  this  Policy,  or  vice
versa.

3

9.

No Indemnification

The  Company  shall  not  indemnify  any  Covered  Persons  against  (i)  the  loss  of  erroneously  awarded  Incentive-
Based Compensation or any adverse tax consequences associated with any incorrectly awarded Incentive-Based
Compensation or any recoupment hereunder, or (ii) any claims relating to the Company enforcement of its rights
under this Policy. For the avoidance of doubt, this prohibition on indemnification will also prohibit the Company
from  reimbursing  or  paying  any  premium  or  payment  of  any  third-party  insurance  policy  to  fund  potential
recovery  obligations  obtained  by  the  Covered  Person  directly.  No  Covered  Person  will  seek  or  retain  any  such
prohibited indemnification or reimbursement.

Further, the Company shall not enter into any agreement that exempts any Incentive-Based Compensation from
the  application  of  this  Policy  or  that  waives  the  Company’s  right  to  recovery  of  any  erroneously  awarded
Incentive-Based Compensation and this Policy shall supersede any such agreement (whether entered into before,
on or after the Effective Date).

10.

Covered Person Acknowledgement and Agreement

All  Covered Persons  subject  to  this  Policy  must  acknowledge  their  understanding of, and agreement to comply
with, the Policy by executing the certification attached hereto as Exhibit A. Notwithstanding the foregoing, this
Policy will apply to Covered Persons whether or not they execute such certification.

11.

Successors

This Policy shall be binding and enforceable against all Covered Persons and their beneficiaries, heirs, executors,
administrators or other legal representatives and shall inure to the benefit of any successor to the Company.

12.

Interpretation of Policy

To the extent there is any ambiguity between this Policy and the Final Rules, this Policy shall be interpreted so
that it complies with the Final Rules. If any provision of this Policy, or the application of such provision to any
Covered  Person  or  circumstance,  shall  be  held  invalid,  the  remainder  of  this  Policy,  or  the  application  of  such
provision to Covered Persons or circumstances other than those as to which it is held invalid, shall not be affected
thereby.

In  the  event  any  provision  of  this  Policy  is  inconsistent  with  any  requirement  of  any  Final  Rules,  the
Administrator, in its sole discretion, shall amend and administer this Policy and bring it into compliance with such
rules.

Any  determination  under  this  Policy  by  the  Administrator  shall  be  conclusive  and  binding  on  the  applicable
Covered Person.  Determinations of the Administrator need not be uniform with respect to Covered Persons or
from one payment or grant to another.

4

13.

Amendments; Termination

The  Administrator  may  make  any  amendments  to  this  Policy  as  required  under  applicable  law,  rules,  and
regulations, or as otherwise determined by the Administrator in its sole discretion.

The Administrator may terminate this Policy at any time.

I have read and understand the Company’s Compensation Recovery Policy (the “Policy”).  I understand that
the Company’s Corporate Legal Counsel is available to answer any questions I have regarding the Policy.

I understand that the Policy applies to all of my existing and future compensation-related agreements with the
Company, whether or not explicitly stated therein.

I agree that notwithstanding the Company’s restated articles of association and any agreement I have with the
Company, including any indemnity agreement I have with the Company, I will not be entitled to, and will not
seek  indemnification  from  the  Company  for,  any  amounts  recovered  or  recoverable  by  the  Company  in
accordance with the Policy.

I  understand  and  agree  that  in  the  event  of  a  conflict  between  the  Policy  and  the  foregoing  agreements  and
understandings on the one hand, and any prior, existing or future agreement, arrangement or understanding,
whether  oral  or  written,  with  respect  to  the  subject  matter  of  the  Policy  and  this  Certification,  on  the  other
hand,  the  terms  of  the  Policy  and  this  Certification  shall  control,  and  the  terms  of  this  Certification  shall

Incentive-Based Compensation to the Company to the extent required by, and in a manner permitted by, the
Policy.

Calculation Guidelines

i.

ii.

iii.

For cash awards not paid from bonus pools, the erroneously awarded compensation is the difference
between the amount of the cash award (whether payable as a lump sum or over time) that was received
and the amount that should have been received applying the restated Financial Reporting Measure.

For cash awards paid from bonus pools, the erroneously awarded compensation is the pro rata portion
of  any  deficiency  that  results  from  the  aggregate  bonus  pool  that  is  reduced  based  on  applying  the
restated Financial Reporting Measure.

For equity awards, if the shares, options, warrants, restricted share units, or SARs are still held at the
time of recovery, the erroneously awarded compensation is the number of such securities received in
excess  of  the  number  that  should  have  been  received  applying  the  restated  Financial  Reporting
Measure (or the value of that excess number).  If the options, warrants or SARs have been exercised,
but the underlying shares have not been sold, the erroneously awarded compensation is the number of
shares underlying the excess options, warrants or SARs (or the value thereof).  If the underlying shares
have been sold, the Company may recoup proceeds received from the sale of shares.

iv.

For  Incentive-Based  Compensation  based  on  share  (or  ADS)  price  or  TSR,  where  the  amount  of
erroneously  awarded  compensation  is  not  subject  to  mathematical  recalculation  directly  from  the
information in an accounting restatement:

a. The amount must be based on a reasonable estimate of the effect of the accounting restatement on
the  share  (or  ADS)  price  or  TSR  upon  which  the  Incentive-Based  Compensation  was  Received;
and

b. The Company must maintain documentation of the determination of that reasonable estimate and

the Company must provide such documentation to the Exchange in all cases.
