ii

Summary of Risk Factors

The following is a summary of some of the risks and uncertainties that could materially adversely affect our business, financial condition and
results of operations. You should read this summary together with the more detailed description of each risk factor contained below.

Risks relating to the manufacturing, marketing and sales of our products

• We  currently  have  only  two  products  approved  for  use  for  specific  indications.  Our  ability  to  expand  our  product  line  and  their  uses

requires regulatory approval, which is costly and requires significant time and effort to obtain.

•

•

To  date,  we  have  generated  only  limited  and  intermittent  operating  profits,  and  we  have  a  history  of  incurring  substantial  operating
losses. As we expand, we may experience difficulties managing our growth.

To  obtain  approvals  for  new  products  and  indications  and  to  continue  to  market  our  existing  products,  we  are  required  to  conduct
preclinical and clinical studies and other testing. Our clinical studies could be delayed or otherwise adversely affected by many factors,
including  difficulties  in  enrolling  patients  and  problems  with  third-party  providers.  Continued  testing  of  our  products  may  not  yield
successful  results  and  could  reveal  currently  unknown  safety  hazards  associated  with  our  products. We  may  choose  to,  or  may  be
required to, suspend, repeat or terminate our clinical studies if they are not conducted in accordance with regulatory requirements, the
results are negative or inconclusive or the studies are not well designed.

• Our products do not have a significant history in the marketplace, as a result we may have difficulty:

◦

◦

◦

developing an adequate sales and marketing organization or contracting with third parties to assist us in doing so;

achieving market acceptance of our products by healthcare professionals, patients and/or third-party payers; and

securing and maintaining adequate coverage and reimbursement from third-party payers, including governmental agencies in
the countries where we market our products.

• We depend on single-source suppliers for some of our components, the loss of which could prevent or delay shipments of our products

to customers or delay our clinical studies.

• Quality control problems with respect to materials supplied by third-party suppliers could prevent or delay shipments of our products to

customers or delay our clinical studies.

• We face competition from numerous competitors.

•

•

Because of the specialized nature of our business, the termination of relationships with our key employees, consultants and advisors
may be detrimental to our business.

Product  liability  suits,  whether  or  not  meritorious,  could  be  brought  against  us  and  result  in  expensive  and  time-consuming  litigation,
payment of substantial damages and/or expenses and an increase in our insurance rates.

• Other future litigation and regulatory actions could have a material adverse impact on the Company.

• We are subject to fluctuations in global economic, political, environmental, and industry conditions, some of which may be unfavorable,

including as a result of the COVID-19 pandemic.

• Our  products  and  infrastructure  face  certain  risks,  including  from  cyber  security  breaches  and  data  leakage.  We  are  also  subject  to

privacy and data security laws.

Risks relating to the regulation of our business

•

Legislative and regulatory changes in the U.S. and in other countries regarding healthcare and government-sponsored programs may
adversely affect us.

• We are subject to extensive post-marketing regulation by the U.S. Federal Drug Administration ("FDA") and comparable authorities in

other jurisdictions, which could cause us to incur significant costs to maintain compliance.

• Modifications  to  our  products  may  require  regulatory  approvals  and  our  regulators  may  not  agree  with  our  conclusions  regarding
whether new approvals are required. Regulatory authorities may require us to cease promoting or to recall the modified versions of our
products until such approvals are obtained.

•

•

In  addition  to  FDA  requirements,  we  will  spend  considerable  time  and  money  complying  with  other  federal,  state,  local  and  foreign
rules, regulations and guidance.

If  we,  our  collaborative  partners,  our  contract  manufacturers,  or  our  component  suppliers  fail  to  comply  with  regulations,  the
manufacturing and distribution of our products could be interrupted.

• Our products could be subject to recalls that could harm our reputation and financial results.

•

If our 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.

• We are not permitted to promote the use of our products for unapproved or off-label uses.

• We  pay  taxes  in  multiple  jurisdictions  and  adverse  determinations  by  governmental  authorities  or  changes  in  tax  laws,  rates  or  our

status under which tax jurisdictions apply to us could increase our tax burden or subject our shareholders to additional taxes.

• We are affected by and subject to environmental laws and regulations that could be costly to comply with or that may result in costly

liabilities.

•

Safety issues concerning lithium-ion batteries could have a material adverse impact on our business.

Risks relating to intellectual property

•

•

If  we  fail  to  protect,  sustain,  further  build  and  enforce  our  intellectual  property  rights,  competitors  may  be  able  to  develop  competing
therapies.

Intellectual  property  litigation  and  disputes  may  cause  us  to  incur  substantial  costs,  divert  attention  from  the  management  of  our
business, harm our reputation, or require us to remove certain products from the market.

• Changes in U.S. patent law could impair our ability to protect our devices.

Risks relating to our ordinary shares and capital structure

•

The market price for our ordinary shares may be volatile, which could result in substantial losses.

• Our ordinary shares are issued under the laws of Jersey, which may not provide the level of legal certainty and transparency afforded

by incorporation in a U.S. state.

• U.S. shareholders may not be able to enforce civil liabilities against us.

• We have borrowed a significant amount of debt and have the ability to borrow additional debt in the future.

•

Transactions relating to our convertible notes may dilute the ownership interest of existing shareholders, or may otherwise depress the
price of our ordinary shares.

ITEM 1.  BUSINESS

Overview

PART I

We are a global oncology company with a proprietary platform technology called Tumor Treating Fields ("TTFields"), which are electric fields
that exert physical forces to kill cancer cells via a variety of mechanisms. Our key priorities are to drive commercial adoption of Optune and
Optune Lua, our commercial TTFields devices, and to advance clinical and product development programs intended to extend overall survival
in some of the most aggressive forms of cancer.

Optune  is  approved  by  the  U.S.  Food  and  Drug  Administration  ("FDA")  under  the  Premarket  Approval  ("PMA")  pathway  for  the  treatment  of
adult patients with newly diagnosed glioblastoma ("GBM") together with temozolomide, a chemotherapy drug, and for adult patients with GBM
following  confirmed  recurrence  after  chemotherapy  as  monotherapy  treatment.  We  also  have  a  CE  certificate  to  market  Optune  for  the
treatment of GBM in the European Union ("EU"), as well as approval or local registration in the United Kingdom ("UK"), Japan, Canada and
certain other countries. Optune Lua is approved by the FDA under the Humanitarian Device Exemption ("HDE") pathway to treatment malignant
pleural mesothelioma ("MPM") together with standard chemotherapies. We have also received CE certification in the EU and approval or local
registration to market Optune Lua in certain other countries. We market Optune and Optune Lua in multiple countries around the globe with the
majority of our revenues coming from the use of Optune in the U.S., Germany and Japan. We are actively evaluating opportunities to expand
our international footprint.

We  believe  the  physical  mechanisms  of  action  behind  TTFields  therapy  may  be  broadly  applicable  to  solid  tumor  cancers.  We  recently
completed patient follow-up and announced top line results from our pivotal LUNAR study evaluating the use of TTFields in the treatment of
non-small cell lung cancer ("NSCLC") together with standard therapies. Patients treated with TTFields and standard therapies demonstrated a
statistically significant and clinically meaningful improvement in overall survival over standard therapies alone. The LUNAR study also showed a
statistically  significant  and  clinically  meaningful  improvement  in  overall  survival  when  patients  were  treated  with  TTFields  and  immune
checkpoint  inhibitors,  as  compared  to  those  treated  with  immune  checkpoint  inhibitors  alone,  and  a  positive  trend  in  overall  survival  when
patients  were  treated  with  TTFields  and  docetaxel  versus  docetaxel  alone.  We  expect  to  present  full  results  of  the  LUNAR  study  at  a  future
medical conference.

In  addition  to  the  LUNAR  study,  we  are  conducting  pivotal  studies  evaluating  the  use  of  TTFields  in  the  treatment  of  ovarian  cancer,  brain
metastases  from  NSCLC  ("brain  metastases")  and  pancreatic  cancer.  We  are  also  conducting  a  pivotal  study  testing  the  potential  survival
benefit of initiating Optune concurrent with radiation therapy versus following radiation therapy in patients with newly diagnosed GBM.

We have one ongoing pilot study evaluating the use of TTFields in the treatment of stage 3 NSCLC and are designing several additional pilot
and  pivotal  studies  in  partnership  with  oncology  leaders  to  further  explore  the  capabilities  of  TTFields.  We  anticipate  expanding  our  clinical
pipeline  over  time  to  study  the  safety  and  efficacy  of  TTFields  for  additional  solid  tumor  indications  and  combinations  with  other  cancer
treatment modalities.

Our therapy is delivered through a medical device and we continue to advance our Products with the intention to extend survival and maintain
quality  of  life  for  patients.  We  have  several  product  development  programs  underway  that  are  designed  to  optimize  TTFields  delivery  to  the
target  tumor  and  enhance  patient  ease  of  use.  Our  intellectual  property  portfolio  contains  hundreds  of  issued  patents  and  numerous  patent
applications pending worldwide. We believe we possess global commercialization rights to our Products in oncology and are well-positioned to
extend those rights into the future as we continue to find innovative ways to improve our Products.

In 2018, we granted Zai Lab (Shanghai) Co., Ltd. ("Zai") a license to commercialize Optune in China, Hong Kong, Macau and Taiwan ("Greater
China") under a License and Collaboration Agreement (the "Zai Agreement"). The Zai Agreement also establishes a development partnership
intended  to  accelerate  the  development  of  TTFields  in  multiple  solid  tumor  cancer  indications.  For  additional  information,  see  Note  12  to  the
Consolidated Financial Statements.

Our  ordinary  shares  are  quoted  on  the  NASDAQ  Global  Select  Market  under  the  symbol  "NVCR."  We  were  incorporated  in  the  Bailiwick  of
Jersey in 2000. Daily management and control of the Company are located in Switzerland, with additional operating centers located around the
world.

Our therapy

When cancer develops, rapid and uncontrolled division of unhealthy cells occurs. Electrically charged proteins within the cell are critical for cell
division, making the rapidly dividing cancer cells vulnerable to electrical interference. TTFields therapy is a treatment that uses electric fields
which exert physical forces to kill cancer via a variety of mechanisms.

All cells are surrounded by a bilipid membrane, which separates the interior of the cell, or cytoplasm, from the space around it. This membrane
prevents  low  frequency  electric  fields  from  entering  the  cell.  TTFields,  however,  have  a  unique  frequency  range,  between  100  to  500  kHz,
enabling the electric fields to penetrate the cancer cell membrane. As healthy cells differ from cancer cells in their division rate, geometry and
electric properties, the frequency of TTFields can be tuned to specifically affect the cancer cells while leaving healthy cells mostly unaffected.

Whether  cells  are  healthy  or  cancerous,  cell  division,  or  mitosis,  is  the  same.  When  mitosis  starts,  charged  proteins  within  the  cell,  or
microtubules, form the mitotic spindle. The spindle is built on electric interaction between its building blocks. During division, the mitotic spindle
segregates the chromosomes, pulling them in opposite directions. As the daughter cells begin to form, electrically polarized molecules migrate
towards the midline to make up the mitotic cleavage furrow. The furrow contracts and the two daughter cells separate. TTFields can interfere
with  these  conditions.  When  TTFields  are  present  in  a  dividing  cancer  cell,  they  cause  the  electrically  charged  proteins  to  align  with  the
directional  forces  applied  by  the  field,  thus  preventing  the  mitotic  spindle  from  forming.  Electrical  forces  also  interrupt  the  migration  of  key
proteins to the cell midline, disrupting the formation of the mitotic cleavage furrow. Interfering with these key processes disrupts mitosis and can
lead to cell death.

Our track record of fundamental scientific research extends across more than two decades and, in all of our preclinical research to date, the
application of TTFields has demonstrated a consistent anti-mitotic effect. Recent preclinical work suggests that the well-established impairment
created  by  the  physical  effect  of  TTFields  to  tumor  cells  results  in  a  series  of  changes  to  cell  processes  that  downregulate  DNA  damage
response, interfere with cell movement and migration, and increase anti-tumor immunity. Research is ongoing to further refine and build upon
our understanding of TTFields' several mechanisms of action. Beyond our internal research efforts, we provide independent researchers with
preclinical laboratory bench systems, known as inovitro™ and inovivo™, and we grant funding to support basic and translational research on
TTFields.  We  also  support  independent  research  through  our  Investigator-Sponsored  Trials  and  Preclinical  Material  Transfer  Agreement
programs in order to enhance our understanding of the optimal use of TTFields.

TTFields  is  intended  principally  for  use  together  with  other  standard-of-care  cancer  treatments.  There  is  a  growing  body  of  evidence  that
supports  TTFields'  broad  applicability  with  certain  other  cancer  therapies,  including  radiation  therapy,  certain  chemotherapies  and  certain
immunotherapies. In our clinical research and commercial experience to date, TTFields has exhibited no systemic toxicity, with mild to moderate
skin irritation being the most common side effect.

Our technology

TTFields  therapy  is  delivered  through  a  portable  medical  device.  The  complete  devices,  called  Optune  and  Optune  Lua  (for  GBM  and  MPM
treatment, respectively), include a portable electric field generator, arrays, rechargeable batteries and accessories. Sterile, single-use arrays are
placed  directly  on  the  skin  in  the  region  surrounding  the  tumor  and  connected  to  the  electric  field  generator  to  deliver  therapy.  Arrays  are
changed when hair growth or the hydrogel reduces array adhesion to the skin. The therapy is designed to be delivered continuously throughout
the day and night, and efficacy is strongly correlated to time on therapy. When the device is turned on, TTFields are continuously generated
within the specific region of the body covered by the arrays. Healthy tissues located outside of this region remain unaffected by the therapy. The
electric field generator can be run from a standard power outlet or carried with a battery in a specially designed bag that we provide to patients.

We plan to use the same field generator technology across all indications for which our Products are approved. We plan to specifically target
individual solid tumor types by optimizing field generator parameters such as frequency and power output. Our arrays have been developed and
are in use, either commercially or clinically, for application on the head, thorax and abdomen.

Through engineering efforts, we plan to continue to advance our Products to optimize TTFields therapy for patients. We have several product
development  programs  underway  designed  to  extend  survival  and  enhance  quality  of  life.  Our  product  development  programs  are  primarily
focused  on  enhancements  to  the  field  generator,  arrays  and  software  applications.  Our  product  development  initiatives  include,  but  are  not
limited to: next generation arrays that

2

are thinner, lighter and more flexible, next generation array layout mapping software, development of a third generation device that optimizes
the use of electric fields to treat tumors, and patient-centered software that enables scaled patient support as we prepare to treat larger patient
populations across multiple indications. Our ultimate goal is to optimize the energy delivered to patients' tumors, potentially improving efficacy.
Any enhancements will be subject to applicable regulatory reviews and approvals.

Our commercial business

Optune is currently marketed for the treatment of GBM, the most common form of primary brain cancer and an aggressive disease for which
there  are  few  effective  treatment  options.  Optune  Lua  is  currently  marketed  for  the  treatment  of  MPM,  a  rare  cancer  that  has  been  strongly
linked  to  asbestos  exposure.  We  market  Optune  and  Optune  Lua  in  multiple  countries  around  the  globe  with  the  majority  of  our  revenues
coming from the use of Optune in the U.S., Germany and Japan.

Treatment of newly diagnosed GBM

In  2015,  we  received  FDA  approval  to  market  Optune  for  the  treatment  of  adult  patients  with  newly  diagnosed  supratentorial  GBM  in
combination  with  temozolomide.  The  FDA  approved  Optune  for  newly  diagnosed  GBM  based  on  the  EF-14  study  ("EF-14"),  which  was  a
randomized pivotal clinical study which compared, post radiation, Optune plus temozolomide versus temozolomide alone for the treatment of
newly  diagnosed  GBM.  The  primary  endpoint  of  the  study  was  progression-free  survival  and  a  powered  secondary  endpoint  was  overall
survival.

In EF-14, Optune plus temozolomide demonstrated unprecedented five-year survival results. Median overall survival was extended by nearly
five  months  (median  overall  survival  of  20.9  months  versus  16.0  months  for  temozolomide  alone).  Median  progression-free  survival  was
extended  by  2.7  months  to  6.7  months  for  Optune  plus  temozolomide  from  4.0  months  for  temozolomide  alone.  The  final  EF-14  data  were
published in the Journal of the American Medical Association in 2017.

The following graph presents the overall survival data in the intent-to-treat population from our five-year analysis:

The extension of progression-free and overall survival in patients receiving Optune in combination with temozolomide in EF-14 was not specific
to  any  prognostic  subgroup  or  tumor  genetic  marker  and  was  consistent  regardless  of  MGMT  methylation  status,  extent  of  resection,  age,
performance status or gender. Optune was safely combined with temozolomide with no significant increase in serious adverse events compared
with temozolomide alone. The most common side effect related to Optune was mild to moderate skin irritation.

Quality of life data from a pre-specified analysis of EF-14 demonstrated that patients treated with Optune and temozolomide maintained quality
of  life  over  time  and  across  predefined  daily-functioning  domains.  Both  healthcare  professionals  and  patients  reported  stable  quality  of  life
evaluation scores up to one year of Optune use. Physical, role, social, emotional and cognitive functioning for patients treated with Optune and
temozolomide all remained stable and comparable with patients treated with temozolomide alone.

3

The  National  Comprehensive  Cancer  Network  Clinical  Practice  Guidelines  in  Oncology®  (NCCN  Guidelines®)  for  Central  Nervous  Systems
Cancers  were  updated  to  include  alternating  electric  fields  therapy  (Optune)  in  combination  with  temozolomide  following  standard  brain
radiation therapy with concurrent temozolomide as a Category 1 recommended postoperative adjuvant treatment option for patients with newly
diagnosed supratentorial GBM.

A  post-hoc  analysis  of  EF-14  showed  that  more  time  on  Optune  predicted  increased  survival  in  GBM  patients.  An  Optune  monthly  usage
threshold  as  low  as  50  percent  correlated  with  significantly  improved  outcomes  in  patients  treated  with  Optune  together  with  temozolomide
compared to patients treated with temozolomide alone. The greater the patients’ monthly usage of Optune, the better their outcomes. Patients
who  used  Optune  more  than  90  percent  of  the  time  (n=43)  had  the  greatest  chance  of  survival:  a  median  survival  of  24.9  months  from
randomization and a five-year probability of survival of 29.3 percent.

A separate post-hoc analysis of EF-14 showed that higher intensities at the tumor bed were associated with increased survival in GBM patients.
Patients  treated  with  Optune  at  higher  intensities  (greater  than  or  equal  to  1.06  V/cm;  n=119)  had  a  median  overall  survival  of  24.3  months
compared to a median overall survival of 21.6 months for patients treated with Optune at lower intensities (less than 1.06 V/cm; n=221).

In  these  analyses,  both  time  on  therapy  and  higher  intensity  were  associated  with  improved  overall  survival,  independent  of  each  other.  In
addition,  patients  who  used  Optune  at  least  18  hours  per  day  at  higher  intensity  levels  (n=78)  had  a  median  overall  survival  of  25.1  months
(95% CI 20.8-39.4).

Treatment of recurrent GBM

We  initially  received  FDA  approval  for  Optune  in  2011  for  use  as  a  monotherapy  treatment  for  adult  patients  with  GBM,  following  confirmed
recurrence after chemotherapy. The FDA approved Optune based on the EF-11 study ("EF-11"), a randomized, pivotal clinical study.

EF-11  was  a  multi-center,  active  controlled  clinical  study  of  237  adults  with  recurrent  GBM.  Participants  received  either  Optune  as  a
monotherapy (n=120) or the physician’s choice of chemotherapy (n=117). Chemotherapies chosen for the active control arm included mainly
bevacizumab, nitrosoureas and temozolomide. The primary endpoint was superiority in overall survival. Overall survival for patients treated with
Optune  alone  and  active  chemotherapy  was  6.6  months  and  6.0  months,  respectively  (p=0.27:  HR  =  0.86).  The  study  demonstrated  that
Optune provided clinically comparable survival with an overall better quality of life.

More objective radiological responses were observed in the Optune group than in the active control chemotherapy group (14 patients versus 7
patients). Three patients in the Optune alone arm had a complete response versus no patients in the active chemotherapy arm.

In  2020,  the  EF-19  post-approval  registry,  which  was  a  post-approval  study  required  as  a  condition  of  FDA  approval,  confirmed  the
effectiveness  and  safety  of  Optune  as  monotherapy  and  further  strengthened  Optune's  clinical  profile  in  recurrent  GBM.  The  EF-19  study
studied Optune as a monotherapy for the treatment of recurrent GBM in 192 patients compared to the 117 recurrent GBM patients who received
best  standard  of  care  chemotherapy  in  Novocure’s  EF-11  registration  study.  Optune  as  monotherapy  reduced  the  risk  of  death  with  fewer
adverse events compared to best standard of care chemotherapy. For patients who received at least one course of therapy, Optune prolonged
survival by a median 1.7 months. No new safety signals were noted.

Treatment of MPM

In  2019,  we  received  FDA  approval  via  the  HDE  pathway  to  market  Optune  Lua  (then  known  as  NovoTTF-100L)  for  the  treatment  of  adult
patients  with  unresectable,  locally  advanced  or  metastatic  MPM  concurrent  with  pemetrexed  and  platinum-based  chemotherapy.  The  FDA
approved  Optune  Lua  for  MPM  based  on  the  STELLAR  study  ("STELLAR").  STELLAR  was  a  single-arm,  open-label,  multi-center  study
designed to test the safety and efficacy of Optune Lua in combination with pemetrexed combined with cisplatin or carboplatin in patients with
unresectable, previously untreated MPM. The study was powered to prospectively determine the overall survival in patients treated with Optune
Lua plus chemotherapy. Secondary endpoints included overall response rate (per mRECIST criteria), progression-free survival and safety.

STELLAR investigated safety and efficacy among 80 patients treated with Optune Lua plus standard of care chemotherapy. In STELLAR, the
median  overall  survival  was  18.2  months  (95%  CI,  12.1-25.8  months)  across  all  patients  treated  with  Optune  Lua  plus  chemotherapy.  The
median  overall  survival  was  21.2  months  for  patients  with  epithelioid  MPM  (n=53)  and  12.1  months  for  patients  with  non-epithelioid  MPM
(n=27). 62% of patients enrolled in STELLAR who used Optune Lua plus chemotherapy were still alive at one year, with 42% of patients alive at
two

4

years.  The  disease  control  rate  in  patients  with  at  least  one  follow-up  CT  scan  performed  (n=72)  was  97%.  40%  of  patients  had  a  partial
response, 57% had stable disease, and 3% had progressive disease. The median progression-free survival was 7.6 months (95% CI, 6.7-8.6
months).

There was no increase in serious systemic adverse events when Optune Lua was added to chemotherapy. Mild-to-moderate skin irritation was
the only device-related side effect with Optune Lua. The STELLAR data were published in The Lancet Oncology in 2019.

Our commercial markets

We have built a commercial organization and market Optune and Optune Lua for the treatment of GBM and MPM in multiple countries in North
America, Europe and Asia.

In 2023, we estimate that approximately:

•

•

•

15,000 people will be diagnosed with GBM or tumors that typically progress to GBM in the U.S. Of this population, we estimate that
approximately 8,200 patients who are candidates for treatment with Optune based upon the rate of disease progression and medical
eligibility will actively seek treatment.

4,600 people will be diagnosed with GBM or tumors that typically progress to GBM in Germany. Of this population, we estimate that
approximately 2,500 patients who are candidates for treatment with Optune based upon the rate of disease progression and medical
eligibility will actively seek treatment.

2,200  people  will  be  diagnosed  with  GBM  or  tumors  that  typically  progress  to  GBM  in  Japan.  Of  this  population,  we  estimate  that
approximately 1,200 patients who are candidates for treatment with Optune based upon the rate of disease progression and medical
eligibility will actively seek treatment.

In  2023,  we  estimate  that  approximately  3,000  people  are  diagnosed  with  malignant  plural  mesothelioma  in  the  U.S.  each  year.  Of  this
population,  we  estimate  that  approximately  1,600  patients  are  candidates  for  treatment  with  Optune  Lua  based  upon  the  rate  of  disease
progression and medical eligibility.

We believe there are many more patients who could benefit from treatment with TTFields than are currently on therapy. We continue to focus on
increasing penetration for GBM and MPM. In the future, we anticipate strategically expanding into additional geographic markets and additional
indications, pending regulatory approval.

Commercial execution

As of December 31, 2022, we had 102 sales force colleagues globally. Healthcare providers must undergo a certification training in order to
prescribe our Products.

With respect to the treatment of GBM, our sales and marketing efforts are principally focused on driving adoption with both neuro-oncologists
and radiation oncologists. In certain countries, neurosurgeons and medical oncologists also drive adoption. We continue to focus on driving key
academic center engagements.

With respect to the treatment of MPM, our sales and marketing efforts are principally focused on certification training, supporting the required
Institutional  Review  Board  approval  process  in  certain  geographies,  and  driving  awareness  among  radiation  oncologists  and  thoracic
oncologists. We believe the benefit of our education efforts will extend beyond MPM to future indications treated by the same prescribers.

We currently operate as a direct-to-patient distributor of our Products, except for Japan. In Japan, we distribute Optune through hospitals and
provide patient support services under a contractual arrangement with the hospital. Once an eligible patient is identified by a certified prescriber,
the healthcare provider’s office submits a prescription order form and supporting documentation to us. We employ a team of Device Support
Specialists who provide technical training to the patient and any caregivers. Once treatment is initiated, we provide 24/7 technical support for
patients and caregivers as well as assistance with insurance reimbursement. We also provide the healthcare provider and the patient with a
usage report for monitoring patient time on therapy. We believe we have the experience and expertise to scale our sales and marketing efforts.

Billing and reimbursement

We provide our Products directly to patients following receipt of a prescription order and a signed patient service agreement (except in Japan as
described above). The number of active patients on therapy and the amount of net

5

revenue  recognized  per  active  patient  are  our  principal  revenue  drivers.  An  active  patient  is  a  patient  who  is  receiving  treatment  under  a
commercial prescription order as of the measurement date, including patients who may be on a temporary break from treatment and who plan
to resume treatment in less than 60 days. Growth in the number of active patients is a factor of both new patient starts and treatment duration.

We  bill  payers  a  single  monthly  fee  for  a  month  of  therapy  and  we  bear  the  financial  risk  of  securing  payment  from  third-party  payers  and
patients in all markets except for Japan. We distribute our Products through hospitals in Japan with the hospitals receiving reimbursement from
the  government-mandated  insurance  program  and  in  turn  contracting  with  us  for  the  equipment,  supplies  and  services  necessary  to  treat
patients with our Product.

We maintain a monthly list price for our therapy in the U.S. and set list prices outside of the United States that are approximately equivalent to
this price, subject to currency fluctuations. We typically negotiate discounts from our list price with healthcare payers, and in certain cases we
accept government-mandated discounts from our list prices in order to secure reimbursement for our Products.

We  continue  to  work  with  payers  to  expand  access  to  Optune  for  patients  with  GBM.  As  of  December  31,  2022,  we  have  received  national
reimbursement  for  Optune  in  Austria,  Germany,  Israel,  Japan,  Sweden  and  Switzerland.  In  February  2023,  we  finalized  contract  terms  to
establish national reimbursement in France for the treatment of adult patients with newly diagnosed GBM, pending official signatures and final
publication in the Journal Officiel.

In  the  U.S.,  a  substantial  majority  of  Americans  with  private  health  insurance  had  coverage  of  Optune  for  newly  diagnosed  GBM  and/or
recurrent GBM as of December 31, 2022. As of September 2019, Americans who are beneficiaries of the Medicare fee-for-service program also
have coverage of Optune for newly diagnosed GBM. We believe we have completed our administrative ramp-up towards processing Medicare
claims  and  are  efficiently  pursuing  appeals.  We  are  actively  appealing  Medicare  fee-for-service  coverage  denials  up  to  and  including  the
Administrative Law Judge ("ALJ") process with Centers for Medicare and Medicaid Services ("CMS").

We  are  engaged  in  an  initial  dialogue  with  certain  payers  regarding  access  to  Optune  Lua  for  patients  with  MPM.  We  anticipate  that  MPM
claims during initial commercialization will go through an appeal process with payers, similar to our early experience with GBM. We anticipate
that our ability to gain meaningful coverage for Optune Lua will be dependent on inclusion in the relevant clinical guidelines for MPM.

Our development pipeline

Based on the results of our preclinical research, we have developed a pipeline strategy to advance TTFields through pilot and pivotal studies
across multiple solid tumor types. We anticipate expanding our clinical pipeline over time to include additional solid tumor cancer indications.

Current Development Pipeline

The  solid  tumor  cancers
subject to our pilot and pivotal studies, as well as the studies themselves, are described in greater detail below. In addition to our studies in
tumors of the head, thorax and abdomen, we continue to conduct

6

research in our approved indications to further advance the scientific evidence supporting the use of TTFields in GBM and to gather additional
information about our therapy's optimal use.

Glioblastoma

GBM is the most common and aggressive form of primary brain cancer. It is estimated that approximate 15,000 patients are diagnosed with
GBM or tumors that typically progress to GBM each year in the U.S. Following diagnosis, standard of care treatment includes surgical resection,
followed by radiotherapy with concomitant chemotherapy, followed TTFields together with maintenance chemotherapy.

2-THE-TOP pilot study

In  2021,  Dr.  David  Tran,  Chief  of  the  Division  of  Neuro-Oncology  at  the  University  of  Southern  California  Keck  School  of  Medicine  and  co-
Director  of  the  USC  Keck  Brain  Tumor  Center,  presented  updated  data  from  the  pilot  2-THE-TOP  study  testing  the  safety  and  efficacy  of
TTFields together with pembrolizumab and temozolomide for the treatment of adult patients with newly diagnosed GBM. As of May 24, 2021, 25
patients with a median age of 61 years were enrolled in the study, with a median follow-up of 14.7 months. 32% had biopsy only and 16% had
partial resection. 72% had unmethylated MGMT and 12% had an IDH mutation. 48% were progression-free, and 60% were still alive. Of the 19
patients with follow-up greater than 9 months, the median progression-free survival was at least 11.2 months compared to 6.7 months from the
historical control study, EF-14, in which patients received TTFields and adjuvant temozolomide. 24% patients with measurable tumors achieved
partial or complete response. 193,760 peripheral blood mononuclear cells were sequenced in 12 patients before pembrolizumab and detected
robust post-TTFields T cell activation in 11 of 12 patients via the T1IFN trajectory with a strong correlation with the TCRαβ clonal expansion
Simpson index (Spearman coefficient r=-0.8, P=0.014). The study defined a T cell-based gene signature of TTFields effects on TCRαβ clonal
expansion. The most common adverse events were thrombosis (16%), seizure (12%), and metabolic disturbances (8%).

In March 2022, Dr. Tran presented updated results from the 2-THE-TOP study. These preliminary results, which are based on a median follow-
up time of 16.8 months, compared outcomes for 26 patients in the ongoing 2-THE-TOP study versus a historical, matched-control group of 26
patients  from  the  EF-14  study.  For  patients  in  the  2-THE-TOP  study,  median  progression-free  survival  was  12.1  months,  compared  with  7.9
months for the matched-control patients in EF-14 (hazard ratio=0.46, p=0.033). Patients in 2-THE-TOP had a median overall survival of 25.2
months, compared with 15.9 months for the matched-control patients in EF-14 (hazard ratio=0.38, p=0.020). Of the 15 patients in 2-THE-TOP
with measurable target lesions, six (40%) achieved partial to complete response and eight (53%) had stable disease.

The 2-THE-TOP study concluded that the triple combination of TTFields, temozolomide, and pembrolizumab is well tolerated and shows early
evidence of efficacy in newly diagnosed GBM patients. Patients will continue follow-up with survival and molecular data to be updated. In 2022,
we entered into a clinical collaboration agreement with MSD, a tradename of Merck & Co., Inc., ("MSD") to conduct the double-blind, placebo-
controlled pivotal KEYNOTE D58 study of TTFields concomitant with pembrolizumab and maintenance temozolomide for the treatment of newly
diagnosed GBM.

EF-33 pilot study

In  October  2022,  we  announced  preliminary  data  from  our  EF-33  pilot  study,  an  open-label,  single-arm  study  evaluating  whether  TTFields
delivered at 200 kHz to the brain using high-intensity arrays in the treatment of recurrent GBM significantly improves the clinical outcomes of
patients compared to using standard transducer arrays in 25 patients. Among patients who used Optune as directed with for at least one month,
median  progression-free  survival  was  4.5  months  compared  to  2.2  months  in  the  historical  control,  our  pivotal  EF-11  study.  Further,
notwithstanding the increased dosage, EF-33 patients reported no TTFields-related toxicity.

TRIDENT pivotal study

In 2020, we enrolled the first patient in our TRIDENT study ("TRIDENT"), a pivotal study testing the potential survival benefit of initiating Optune
concurrent with radiation therapy in patients with newly diagnosed GBM. The primary endpoint is overall survival. Secondary endpoints include
progression-free  survival,  survival  rates  at  one  and  two  years,  overall  radiological  response,  severity  and  frequency  of  adverse  effects,
pathological changes in

7

resected GBM tumors post treatment, quality of life, and correlation of overall survival to TTFields dose. TRIDENT is designed to accrue 950
patients with a 24-month minimum follow-up period after the last patient enrolled.

Non-small cell lung cancer

Lung cancer is the most common cause of cancer-related death worldwide, and NSCLC accounts for approximately 85% of all lung cancers. It
is estimated that approximately 193,000 patients are diagnosed with NSCLC each year in the U.S.

Physicians  use  different  combinations  of  surgery,  radiation  and  pharmacological  therapies  to  treat  NSCLC,  depending  on  the  stage  of  the
disease.  Surgery,  which  may  be  curative  in  a  subset  of  patients,  is  usually  used  in  early  stages  of  the  disease.  A  combination  of  radiation,
platinum-based chemotherapies, and immune checkpoint inhibitors, or targeted therapies, are the first line standard of care treatment for locally
advanced  or  metastatic  NSCLC.  Today,  the  standard  of  care  for  second  line  treatment  is  evolving  and  often  includes  immune  checkpoint
inhibitors, docetaxel, platinum-based chemotherapy or pemetrexed.

EF-15 pilot study

In 2013, we published the results of our pilot study, the EF-15 study ("EF-15"), evaluating the safety and efficacy of TTFields in the treatment of
advanced NSCLC. EF-15 focused on the effects of treatment with TTFields in combination with standard of care pemetrexed chemotherapy.
Results of the pemetrexed pivotal FDA registration study were used as a historical control in this study.

A  total  of  42  patients  were  recruited  to  the  study  with  a  minimum  follow-up  of  six  months.  Efficacy  results  based  on  41  evaluable  patients
showed both progression-free survival and overall survival for patients receiving TTFields in combination with pemetrexed increased compared
to historical control data for pemetrexed alone. Median time to in-field progression in the TTFields-treated group was 6.5 months (compared to
2.9 months in the historical control) and median overall survival was 13.8 months (compared to 8.3 months in the historical control). Adverse
events reported in this combination study were comparable to those reported with pemetrexed alone, suggesting minimal added toxicities due
to TTFields.

LUNAR pivotal study

In 2017, we enrolled the first patient in our LUNAR study ("LUNAR"), a pivotal study testing the effectiveness of TTFields in combination with
immune  checkpoint  inhibitors  or  docetaxel  versus  immune  checkpoint  inhibitors  or  docetaxel  alone  for  patients  with  stage  4  NSCLC  who
progressed during or after platinum-based therapy. It is estimated that approximately 46,000 patients receive second-line treatment for stage 4
NSCLC  each  year  in  the  U.S.  The  primary  endpoint  is  superior  overall  survival  of  patients  treated  with  TTFields  plus  immune  checkpoint
inhibitors or docetaxel versus immune checkpoint inhibitors or docetaxel alone. We believe our protocol incorporates the evolving standard of
care for second-line treatment of NSCLC. TTFields is intended principally for use in combination with other standard-of-care treatments, and
LUNAR was designed to generate data that contemplates multiple outcomes, all of which we believe will be clinically meaningful.

In  2021,  we  announced  that  an  independent  Data  Monitoring  Committee  ("DMC")  informed  us  that  the  pre-specified  interim  analysis  for  the
LUNAR study was accelerated given the length of accrual and the number of events observed, to date. The interim analysis included data from
210 patients accrued through February 2021. After review of the interim analysis, the DMC concluded that the LUNAR study should continue
with no evidence of increased systemic toxicity. The DMC went on to comment that the continued accrual to 534 patients as proposed in the
original  protocol,  given  the  current  rate  of  accrual  and  the  interim  data  presented,  is  likely  unnecessary  and  possibly  unethical  for  patients
randomized to control. For this reason, the DMC recommended an adjustment of accrual to approximately 276 patients with a 12-month follow-
up following the enrollment of the last patient. The DMC believed this amended protocol would provide adequate data regarding toxicity and
efficacy, providing sufficient overall power, as well as potentially providing important information regarding efficacy within treatment subgroups.
In  May  2021,  the  FDA  approved  our  investigational  device  exemption  supplement  incorporating  the  recommended  protocol  changes  and  we
enrolled our last LUNAR patient in November 2021.

In January 2023, we announced the LUNAR study met its primary endpoint, demonstrating a statistically significant and clinically meaningful
improvement  in  overall  survival  for  patients  treated  with  TTFields  and  standard  therapies  compared  to  those  treated  with  standard  therapies
alone.  The  LUNAR  study  also  showed  a  statistically  significant  and  clinically  meaningful  improvement  in  overall  survival  when  patients  were
treated with TTFields and immune checkpoint inhibitors, as compared to those treated with immune checkpoint inhibitor alone, and a positive
trend in

8

overall survival when patients were treated with TTFields and docetaxel versus docetaxel alone. Patient enrollment was well balanced between
the immune checkpoint inhibitor and docetaxel cohorts of the experimental and control arms, and the control arms performed in line with prior
studies.  TTFields  therapy  was  well  tolerated  by  patients  enrolled  in  the  experimental  arm  of  the  study.  The  publication  of  full  data  from  the
LUNAR study is anticipated in 2023.

KEYNOTE B36 pilot study

In June 2022, we enrolled the first patient in our KEYNOTE B36 study, a pilot study evaluating the safety and efficacy of TTFields together with
the anti-PD-1 therapy pembrolizumab for the treatment of first-line NSCLC, expanding our research in the lung cancer space. This study is the
result of a clinical study collaboration with MSD.

Brain metastases

Metastatic cancer is cancer that has spread from the place where it first started to another place in the body. In metastasis, cancer cells break
away from where they first formed (the primary cancer), travel through the blood or lymph system, and form new tumors (the metastatic tumors)
in  other  parts  of  the  body.  The  exact  incidence  of  brain  metastases  is  unknown  because  no  national  cancer  registry  documents  brain
metastases, and estimates from scientific literature vary greatly based on the study methodology applied. It is estimated that between 100,000
and 240,000 new cases are diagnosed in the U.S. each year with brain metastases estimated to occur in between 10% to 40% of all cancer
patients.

Brain metastases are commonly treated with a combination of surgery and radiation. Chemotherapy is often given for the primary tumor, but
many  chemotherapy  agents  do  not  cross  the  blood  brain  barrier  and  are  thus  ineffective  in  the  treatment  of  brain  metastases.  When  brain
metastases appear, they are either surgically removed or treated with radiation using stereotactic radiosurgery ("SRS") when possible. Whole
brain radiation therapy, although effective in delaying progression or recurrence of brain metastases when given either before or after SRS, is
associated with neurotoxicity and a significant decline in cognitive functioning. Thus, whole brain radiation therapy is often delayed until later in
the disease course and is often used as a last resort. This practice results in a window of unmet need after localized surgery and SRS are used
and before whole brain radiation therapy is administered to delay or prevent the additional spread of brain metastases.

METIS pivotal study

In 2016, we enrolled the first patient in our METIS study ("METIS"), a pivotal study testing the effectiveness of SRS plus TTFields compared to
SRS alone in patients with brain metastases resulting from NSCLC. It is estimated that between 20 to 40% of patients with NSCLC develop
brain metastases, with an estimated 38,000 to 77,000 patients diagnosed each year in the U.S. with brain metastases resulting from NSCLC.
The  primary  endpoint  of  METIS  is  time  to  first  intracranial  progression.  Secondary  endpoints  include,  among  others,  time  to  neurocognitive
failure, overall survival and radiological response rate following study treatments. The study is designed to accrue 270 patients with a minimum
12-month follow-up period following the final patient enrollment. We anticipate completing enrollment of the METIS study in the first quarter of
2023.

Ovarian cancer

In the U.S., ovarian cancer ranks fifth in cancer deaths among women, with approximately 24,000 women diagnosed each year. Ovarian cancer
incidence increases with age, and the median age at time of diagnosis is 63 years old.

Physicians use different combinations of surgery and pharmacological therapies to treat ovarian cancer, depending on the stage of the disease.
Surgery  is  usually  used  in  early  stages  of  the  disease  and  is  usually  combined  with  chemotherapy,  including  paclitaxel  and  platinum-based
chemotherapy. Unfortunately, the majority of patients are diagnosed at an advanced stage when the cancer has spread outside of the ovaries to
include regional tissue involvement and/or metastases. Platinum-based chemotherapy remains part of the standard of care in advanced ovarian
cancer, but most patients with advanced ovarian cancer will have tumor progression or, more commonly, recurrence. Almost all patients with
recurrent disease ultimately develop platinum resistance, and the prognosis for this population remains poor.

9

INNOVATE pilot study

In  2018,  we  published  the  results  of  our  pilot  study  in  recurrent  ovarian  cancer,  the  INNOVATE  study  ("INNOVATE"),  examining  TTFields  in
combination  with  standard  of  care  chemotherapy.  INNOVATE  was  a  multi-center,  non-randomized,  open-label  study  designed  to  test  the
feasibility, safety and preliminary efficacy of TTFields in combination with weekly paclitaxel. The paclitaxel control arm from the bevacizumab
pivotal FDA registration study was used as a historical control in this study.

A total of 31 patients were recruited to the study with a minimum follow-up of six months. Safety results suggested that TTFields in combination
with weekly paclitaxel may be tolerable and safe as second-line treatment for patients with recurrent ovarian cancer. Median progression-free
survival in the TTFields-treated group was 8.9 months (compared to 3.9 months in the paclitaxel-alone historical control), and median overall
survival was not yet reached. The one-year survival rate was 61%. Efficacy results based on the 31 evaluable patients suggested more than
doubling of the progression-free survival and an improvement in overall survival among patients who received TTFields therapy with paclitaxel
compared to paclitaxel alone.

INNOVATE-3 pivotal study

In  2019,  we  enrolled  the  first  patient  in  our  INNOVATE-3  study  ("INNOVATE-3"),  a  pivotal  study  testing  the  effectiveness  of  TTFields  with
paclitaxel  in  patients  with  platinum-resistant  ovarian  cancer.  It  is  estimated  that  approximately  16,000  patients  are  diagnosed  with  platinum-
resistant  ovarian  cancer  each  year  in  the  U.S.  The  primary  endpoint  of  INNOVATE-3  is  overall  survival.  Secondary  endpoints  include
progression-free survival, objective response rate, severity and frequency of adverse events, time to undisputable deterioration in health-related
quality of life or death, and quality of life. The study is designed to accrue 540 patients with 18-month follow-up after the last patient in. In 2021,
we announced that the final patient was enrolled in the pivotal INNOVATE-3 study. In March 2022, we announced that an independent DMC
conducted  a  pre-specified  interim  analysis  for  the  study.  As  part  of  the  interim  analysis,  the  DMC  reviewed  the  safety  data  for  all  enrolled
patients and completed an analysis of overall survival on the first 540 patients randomized in the study. The interim analysis did not indicate a
need to increase the patient sample size and the DMC recommended that the study should continue to final analysis as planned. We anticipate
that  final  data  will  be  released  in  2023,  following  completion  of  a  minimum  18-month  follow-up  period.  The  European  Network  for
Gynaecological  Oncological  Trial  groups  ("ENGOT")  and  The  GOG  Foundation,  Inc.  ("GOG"),  third-party  clinical  study  networks,  are
collaborating with us on the study.

Pancreatic cancer

Pancreatic cancer is one of the most lethal cancers and is the third most frequent cause of death from cancer in the U.S. While overall cancer
incidence and death rates are remaining stable or declining, the incidence and death rates for pancreatic cancer are increasing. It is estimated
that  approximately  53,000  patients  are  diagnosed  with  pancreatic  cancer  each  year  in  the  U.S.  Pancreatic  cancer  has  a  five-year  relative
survival rate of just 10 percent.

Physicians use different combinations of surgery, radiation and pharmacological therapies to treat pancreatic cancer, depending on the stage of
the  disease.  For  patients  with  locally  advanced  pancreatic  cancer  involving  encasement  of  arteries  but  no  extra-pancreatic  disease,  the
standard  of  care  is  surgery  followed  by  chemotherapy  with  or  without  radiation.  Unfortunately,  the  majority  of  locally  advanced  cases  are
diagnosed once the cancer is no longer operable, generally leaving chemotherapy with or without radiation as the only treatment option.

PANOVA pilot study

In  2018,  we  published  the  results  of  our  pilot  study  in  advanced  pancreatic  adenocarcinoma,  the  PANOVA  study  ("PANOVA"),  examining
TTFields in combination with standard of care chemotherapy.

PANOVA was a multicenter, non-randomized, open-label study. The study included 40 patients with locally advanced or metastatic pancreatic
cancer whose tumors could not be removed surgically and who had not received chemotherapy or radiation therapy prior to the clinical study.
Patients  were  enrolled  between  2014  and  2016  in  two  cohorts:  The  first  cohort  of  20  patients  received  TTFields  with  standard  doses  of
gemcitabine alone. The second cohort of 20 patients received TTFields with standard doses of nab-paclitaxel plus gemcitabine.

In  the  first  cohort,  efficacy  results  showed  that  progression-free  survival  and  overall  survival  of  patients  treated  with  TTFields  combined  with
gemcitabine were more than double those of gemcitabine-treated historical controls. Median progression-free survival in the TTFields-treated
group  was  8.3  months  (compared  to  3.7  months  in  the  gemcitabine  historical  control),  with  locally  advanced  patients  reaching  a  median
progression-free survival of 10.3

10

months  and  patients  with  metastatic  disease  reaching  a  median  progression-free  survival  of  5.7  months.  The  median  overall  survival  for  all
patients  was  14.9  months  (compared  to  6.7  months  in  the  gemcitabine  historical  control).  Median  overall  survival  was  not  reached  in  locally
advanced patients and 86% of patients were alive at end of follow up. Patients with metastatic disease experienced a median overall survival of
8.3  months.  One-year  survival  was  55%  (compared  to  22%  in  the  gemcitabine  historical  control).  Of  11  patients  with  available  CT  scans,  5
(45%) had a partial response (compared to 7% with gemcitabine alone), 5 (45%) had stable disease, which means that the cancer is neither
decreasing nor increasing in extent or severity, and 1 (10%) had progressive disease.

In the second cohort, efficacy results showed that progression-free survival and overall survival of patients treated with TTFields combined with
nab-paclitaxel  plus  gemcitabine  were  more  than  double  those  of  nab-paclitaxel  plus  gemcitabine-treated  historical  controls.  Median
progression-free  survival  in  the  TTFields-treated  group  was  12.7  months  (compared  to  5.5  months  in  the  nab-paclitaxel  plus  gemcitabine
historical control) and median overall survival was not yet reached. The one-year survival rate was 72% (compared to 35% in nab-paclitaxel
plus gemcitabine historical control). Of the 15 patients with available CT scans, 6 (40%) had a partial response (compared to 23% with the nab-
paclitaxel plus gemcitabine alone), 7 (47%) had stable disease and 2 (13%) had progressive disease.

Safety results from both cohorts suggested that TTFields plus first-line chemotherapies nab-paclitaxel and/or gemcitabine may be tolerable and
safe in patients with advanced pancreatic cancer. Patients reported no serious adverse events related to TTFields.

PANOVA-3 pivotal study

In  2018,  we  enrolled  the  first  patient  in  our  PANOVA-3  study  ("PANOVA-3"),  a  pivotal  study  testing  the  effectiveness  of  TTFields  with  nab-
paclitaxel and gemcitabine versus nab-paclitaxel and gemcitabine alone as a front-line treatment for unresectable locally advanced pancreatic
cancer. It is estimated that approximately 43,000 patients are diagnosed with unresectable pancreatic cancer each year in the U.S. The primary
endpoint  of  PANOVA-3  is  overall  survival.  Secondary  endpoints  include  progression-free  survival,  local  progression-free  survival,  objective
response rate, one-year survival rate, quality of life, pain-free survival, resectability rate and toxicity.

The  study  is  designed  to  accrue  556  patients.  In  February  2023,  we  announced  that  the  final  patient  was  enrolled  in  the  pivotal  PANOVA-3
study, beginning the minimum 18-month follow-up period. A DMC will conduct a pre-specified interim analysis pursuant to the study protocol
and final data is anticipated in 2024.

Liver cancer

Liver cancer is a leading cause of cancer deaths worldwide and is the sixth leading cause of cancer deaths annually in the U.S. The incidence
of liver cancer is approximately 42,000 new cases annually in the U.S. The five-year survival rate with existing standards of care is less than
20%.

Hepatocellular carcinoma is the most widespread type of cancer that originates from the liver. Advanced liver cancer has spread either to the
lymph  nodes  or  to  other  organs  and,  because  these  cancers  are  widespread,  they  cannot  be  treated  with  surgery.  The  current  common
standard treatment for patients with advanced disease and those who progressed on loco-regional therapy is systemic therapy with sorafenib,
lenvatinib, or atezolizumab plus bevacizumab.

In  2021,  we  announced  that  the  FDA  granted  breakthrough  designation  to  the  NovoTTF-200T  System,  a  TTFields  device  intended  for  use
together with atezolizumab and bevacizumab for the first-line treatment of patients with unresectable or metastatic liver cancer. The designation
offers  us  an  opportunity  to  interact  with  FDA  experts  throughout  the  premarket  review  phase  and  allows  for  prioritized  review  of  regulatory
submissions.

HEPANOVA pilot study

In  2021,  we  announced  the  final  results  of  our  HEPANOVA  study,  a  single-arm  pilot  study  evaluating  the  safety  and  efficacy  of  TTFields  in
combination with sorafenib for the treatment of advanced hepatocellular cancer. In 21 evaluable patients, HEPANOVA showed a 9.5% objective
response rate and 76% disease control rate, as well as 5.8 months of progression free survival, compared to historical control data showing a
4.5% objective response rate and 43% disease control rate for patients treated with sorafenib alone. These results are even more encouraging
when  considering  the  poor  prognosis  of  the  study  population.  52%  of  the  patients  in  HEPANOVA  were  categorized  as  Child-Pugh  Class  B,
compared to 5% in the historical control, indicating significant liver functional compromise. Additionally, research conducted to date has shown
that TTFields anti-mitotic effect requires extended exposure to

11

the  therapy  for  maximum  impact.  This  was  a  challenge  given  median  patient  treatment  duration  of  only  10  weeks  during  the  study.  Of  the
patients who received at least 12 weeks of therapy, the disease control rate reached 91% with an objective response rate of 18%. These data
demonstrate that TTFields have the potential to extend survival in advanced liver cancer.

Gastric cancer

Gastric cancer is the third leading cause of cancer deaths worldwide and the third leading cause of cancer deaths in China. The incidence of
gastric cancer is approximately 478,500 new cases annually in China, and approximately 26,000 new cases annually in the U.S. The five-year
overall survival rate of gastric cancer is approximately 36%.

Current  therapies  include  surgery,  chemotherapy,  radiotherapy  and  targeted  therapy.  A  commonly  used  chemotherapy  regimen  in  treating
gastric cancer is XELOX, a combination of oxaliplatin and capecitabine. In patients diagnosed with advanced gastric cancer that is no longer
operable, combination chemotherapy extends progression-free survival and overall survival to 3-6 months and 8-14 months, respectively.

EF-31 pilot study

In June 2022, we announced the results from our EF-31 pilot study, a single-arm study evaluating the safety and efficacy of TTFields together
with  XELOX  chemotherapy  (and  trastuzumab  for  HER2-positive  patients)  as  first-line  treatment  for  patients  with  unresectable  gastric
adenocarcinoma  or  gastroesophageal  junction  adenocarcinoma  in  partnership  with  Zai.  In  26  evaluable  patients,  the  primary  endpoint,
confirmed  objective  response  rate,  was  50%,  median  progression-free  survival  was  7.8  months,  duration  of  response  was  10.3  months  and
median overall survival had not yet been reached with a one-year survival rate of 72%.

Zai License and Collaboration Agreement

In 2018, we announced a strategic collaboration with Zai. The collaboration agreement grants Zai a license to commercialize our Products in
Greater China and establishes a development partnership intended to accelerate the development of TTFields in multiple solid tumor cancer
indications. Zai has launched Optune for the treatment of newly diagnosed GBM in Hong Kong and mainland China and is seeking marketing
authorization  for  GBM  in  Taiwan.  Zai  has  also  launched  Optune  Lua  for  the  treatment  of  MPM  in  Hong  Kong  and  has  filed  a  Marketing
Authorization Application for MPM in mainland China. For additional information, see Note 12 to the Consolidated Financial Statements.

Manufacturing and supply chain

We outsource production of all of our system components to qualified partners. Disposable array manufacturing, the dominant activity in our
manufacturing supply chain, includes several specialized processes. Production of the durable system components follows standard electronic
medical device methodologies.

We have supply agreements in place with our third-party manufacturing partners. While we currently obtain some critical materials for use in
certain jurisdictions from single source suppliers, we have developed or are in the process of developing and obtaining regulatory approval for
second  sources  for  critical  materials  in  all  jurisdictions.  We  hold  safety  stocks  of  single  source  components  in  quantities  that  we  believe  are
sufficient  to  protect  against  possible  supply  chain  disruptions.  We  anticipate  that  the  diversification  of  our  supply  chain  will  both  ensure  a
continuity of supply and reduce costs.

Intellectual property

We believe we possess global commercialization rights to our Products in oncology and are well-positioned to extend those rights into the future
as we continue to find innovative ways to improve our Products. Our robust global patent and intellectual property portfolio consists of hundreds
of issued patents in multiple jurisdictions covering various aspects of our devices and related technology. In the U.S., our patents have expected
expiration  dates  between  2023  and  2041.  We  have  also  filed  several  hundred  additional  patent  applications  worldwide,  that,  if  issued,  may
protect aspects of our platform beyond the current last-to-expire patent in the relevant market. These pending applications cover innovations
relating to our arrays, field generators and software platform, in addition to other topics related to TTFields. Our reliance on intellectual property
involves certain risks, as described under the heading "Risk factors—Risks relating to intellectual property."

12

In addition to our patent portfolio, we further protect our intellectual property by maintaining the confidentiality of our trade secrets, know-how
and other confidential information. Given the length of time and expense associated with bringing device candidates through development and
regulatory approval to the market place, the healthcare industry has traditionally placed considerable importance on obtaining patent protection
and maintaining trade secrets, know-how and other confidential information for significant new technologies, products and processes.

Our  policy  is  to  require  each  of  our  employees,  consultants  and  advisors  to  execute  a  confidentiality  agreement  before  beginning  their
employment, consulting or advisory relationship with us. These agreements generally provide that the individual must keep confidential and not
disclose to other parties any confidential information developed or learned by the individual during the course of their relationship with us except
in  limited  circumstances.  These  agreements  also  generally  provide  that  we  own,  or  the  individual  is  required  to  assign  to  us,  all  inventions
conceived by the individual in the course of rendering services to us. Despite measures taken to protect our intellectual property, unauthorized
parties may copy certain aspects of our products or obtain and use information that we believe is proprietary.

Pursuant  to  our  strategic  collaboration  with  Zai,  we  granted  Zai  a  license  to  commercialize  TTFields  in  Greater  China.  For  additional
information, see Note 12 to the Consolidated Financial Statements.

Competition

The  market  for  cancer  treatments  is  intensely  competitive,  subject  to  rapid  change  and  significantly  affected  by  new  product  and  treatment
introductions  and  other  activities  of  industry  participants.  The  general  bases  of  competition  are  overall  effectiveness,  side  effect  profile,  cost,
availability of reimbursement and general market acceptance of a product as a suitable cancer treatment.

Our intellectual property portfolio is continuously expanding as we find new and unique ways to improve TTFields therapy. We  believe  these
intellectual  property  rights  would  provide  an  obstacle  to  the  introduction  of  state  of  the  art  TTFields  devices  by  a  competitor.  However,
competitors  may  be  able  to  offer  less  sophisticated  TTFields  devices  that  utilize  technology  described  in  expired  patents  and/or  choose  to
market  their  system(s)  in  countries  where  we  have  limited  or  no  enforceable  intellectual  property  rights.  Competitors  could  also  pursue
alternative technologies for the application of TTFields into a patient that we did not foresee or protect. We are aware of a few third parties in
the United States and China developing devices and filing for intellectual property protection related to TTFields.

Beginning in 2021, several of our early patents covering technology included in our Products began expiring in the U.S. and elsewhere. Even
after the expiration of our patents, we believe that potential market entrants applying low-intensity, alternating electric fields to solid tumors will
have  to  undertake  their  own  clinical  studies  and  regulatory  submissions  to  prove  equivalence  to  our  Products,  a  necessary  step  in  receiving
regulatory approvals for a competing product, all while avoiding infringing our unexpired patents.

Presently, the traditional biotechnology, pharmaceutical and medical technology industries expend significant resources in developing novel and
proprietary  therapies  for  the  treatment  of  solid  tumors,  including  GBM,  MPM  and  other  indications  that  we  are  currently  investigating.  As  we
work to increase market acceptance of our Products, we compete with companies commercializing or investigating other anti-cancer therapies,
some of which are in clinical studies for GBM or MPM that currently specifically exclude patients who have been or are being treated with our
Products. The introduction of competing therapies could materially impact our business and financial results.

Government regulation

In the U.S., our Products and our operations are subject to extensive regulation by the FDA under the Federal Food, Drug, and Cosmetic Act
("FDCA").  In  the  EU  member  states  where  we  market  our  Products  and  operate,  we  are  currently  subject  to,  inter  alia,  the  Medical  Device
Regulation  ("MDR")  as  implemented  into  national  legislation  by  the  EU  member  states,  and  as  amended  from  time  to  time,  as  well  as  local
applicable  law.  The  MDR  replaced  the  Medical  Device  Directive  ("MDD")  on  May  26,  2021.  In  Switzerland,  our  Products  and  operations  are
subject to, inter alia, the Medical Devices Ordinance, which implements the MDR into Swiss law (See "Foreign approvals and CE mark" below).
In  Japan,  our  Products  and  operations  are  subject  to  regulation  by  the  Pharmaceuticals  and  Medical  Device  Agency  ("PMDA")  under  the
Pharmaceuticals and Medical Devices Act ("PMD Act"). In the UK, our Products and operations are subject to, inter alia, the Medical Devices
Regulations 2002 and the Medical Devices (Amendment etc.) (EU Exit) Regulations 2020 (the "UK Regulations"), which implements the MDR
and MDR like provisions into UK law. In addition, our Products must meet the requirements of a large and growing body of national, regional
and international standards that govern the preclinical and clinical testing, manufacturing, labeling,

13

certification,  storage,  recordkeeping,  advertising,  promotion,  export  and  marketing  and  distribution,  among  other  things,  of  our  Products  for
current and future indications.

In the U.S., advertising and promotion of medical devices, in addition to being regulated by the FDA, is also regulated by the Federal Trade
Commission  and  by  state  regulatory  and  enforcement  authorities.  In  the  EU,  advertising  and  promotion  is  subject  to  not  only  the  general
provisions of the MDR, but also general EU advertising rules on misleading and comparative advertising and unfair commercial practices, as
implemented at the EU member state level, such as the Heilmittelwerbegesetz in Germany. In the UK, advertising and promotion is subject to
the UK Regulations, general guidance and enforcement of the Medicines and Healthcare products Regulatory Agency (MHRA), and adherence
to the Association of British HealthTech Industries (ABHI) Code of Ethical Business Practices. Promotional activities for FDA-regulated products
of other companies have been the subject of government enforcement actions brought under healthcare laws and consumer protection statutes.
In addition, we are required to meet analogous regulatory requirements in countries outside the U.S., which can change rapidly with relatively
short notice. Competitors can also initiate litigation alleging false advertising for our promotional efforts under the Lanham Act, or under similar
state laws.

Our  research,  development  and  clinical  programs,  as  well  as  our  manufacturing  and  marketing  operations,  are  also  subject  to  extensive
regulation.

Failure  by  us  or  by  our  suppliers  to  comply  with  applicable  regulatory  requirements  can  result  in  enforcement  action  by  the  FDA  or  other
regulatory authorities, which may result in any number of regulatory enforcement actions, or civil or criminal liability.

Food and Drug Administration

The FDA regulates the development, testing, manufacturing, labeling, storage, recordkeeping, promotion, marketing, distribution and service of
medical devices in the U.S. to ensure that medical products distributed domestically are safe and effective for their intended uses. In addition,
the  FDA  regulates  the  export  of  medical  devices  manufactured  in  the  U.S.  to  international  markets  and  the  importation  of  medical  devices
manufactured abroad. The FDA has broad post-market and regulatory enforcement powers to ensure compliance with the FDCA.

The FDA governs the following activities that we perform or that are performed on our behalf:

•

•

•

•

•

product design, development and manufacture;

product safety, testing, labeling and storage;

record keeping procedures;

product marketing, sales and distribution; and

post-marketing surveillance, complaint handling, medical device reporting, reporting of deaths, serious injuries or device malfunctions
and repair or recall of products.

We have registered three of our facilities with the FDA. We are subject to announced and unannounced inspections by the FDA to determine
our compliance with the Quality System Regulation ("QSR") and other regulations and these inspections include the manufacturing facilities of
our suppliers.

FDA’s premarket clearance and approval requirements

Unless  an  exemption  applies,  before  we  can  commercially  distribute  medical  devices  in  the  U.S.,  we  must  obtain,  depending  on  the  type  of
device,  either  prior  510(k)  clearance  or  premarket  approval  ("PMA")  from  the  FDA.  The  FDA  classifies  medical  devices  into  one  of  three
classes. Devices deemed to pose lower risks are placed in either class I or II, which typically requires the manufacturer to submit to the FDA a
premarket notification requesting permission to commercially distribute the device. This process is generally known as 510(k) clearance. Some
low-risk  devices  are  exempted  from  this  requirement.  Devices  deemed  by  the  FDA  to  pose  the  greatest  risks,  such  as  life-sustaining,  life-
supporting or implantable devices, or devices deemed not substantially equivalent to a previously cleared 510(k) device, are placed in class III,
generally requiring PMA.

14

Premarket approval (PMA) and Humanitarian Device Exemption (HDE) pathways

Optune and Optune Lua are classified as Class III devices as they are deemed to be life-sustaining devices. Accordingly, we were required to
receive  PMA  for  Optune,  which  the  FDA  granted  in  April  2011  and  October  2015  for  the  treatment  of  recurrent  and  newly  diagnosed
supratentorial  GBM,  respectively,  in  adult  patients.  We  expect  that  we  will  be  required  to  receive  PMA  for  the  use  of  our  Products  for  future
indications.

A PMA must be supported by extensive data, including from technical tests, preclinical studies and clinical studies, manufacturing information
and intended labeling to demonstrate, to the FDA’s satisfaction, the safety and effectiveness of a medical device for its intended use. During the
PMA review period, the FDA will typically request additional information or clarification of the information already provided. Also, an advisory
panel of experts from outside the FDA may be convened to review and evaluate the application and provide recommendations to the FDA as to
the approvability of the device. The FDA may or may not accept the panel’s recommendation. In addition, the FDA will generally conduct a pre-
approval inspection of the manufacturing facility or facilities to ensure compliance with the QSR. Prior to approval of the Optune PMA for the
treatment of recurrent GBM, we and our critical component suppliers were each inspected by the FDA.

New  PMAs  or  PMA  supplements  are  required  for  modifications  that  affect  the  safety  or  effectiveness  of  our  devices,  including,  for  example,
certain  types  of  modifications  to  a  device’s  indication  for  use,  manufacturing  process,  labeling  and  design.  PMA  supplements  often  require
submission of the same type of information as a PMA, except that the supplement is limited to information needed to support any changes from
the device covered by the original PMA and may not require any or as extensive clinical data as the original PMA required, or the convening of
an advisory panel. The FDA requires a company to make the determination as to whether a new PMA or PMA supplement application is to be
filed. If a company determines that neither a new PMA nor a PMA supplement application is required for modifications, it must nevertheless
notify the FDA of these modifications in its PMA Annual Report. The FDA may review a company’s decisions when reviewing the PMA Annual
Report and require the filing of an application.

As is typical with medical device companies, we have received approval for a number of post-approval PMA supplements for GBM, including for
modifications  to  Optune’s  electric  field  generator,  arrays,  software,  manufacturing  processes  and  labeling.  Future  modifications  may  be
considered by us as the need arises, some of which we may deem to require a PMA supplement application and others to require reporting in
our PMA Annual Report.

For class III devices intended to treat disease affecting 8,000 individuals or less per year in the U.S., called Humanitarian Use Devices ("HUD"),
the FDA has a separate marketing authorization pathway called the HDE. Approval basis for an HDE is a "reasonable assurance of safety" and
that the probable benefit to health outweighs risk of injury from its use, which means a traditional pivotal study usually is not required to support
approval.

In 2019, the FDA approved Optune Lua (then known as "NovoTTF-100L") for the treatment of MPM under the HDE pathway. Devices approved
through  an  HDE  application  are  subject  to  certain  requirements,  including  specific  labeling  restrictions  and  the  requirement  that  a  facility’s
institutional review board ("IRB") or Local Committee approve the use of the device before it can be distributed in that facility. In addition, there
is a general prohibition on profiting from sales of devices approved under the HDE standard. As part of the approval process, we applied for an
exemption  from  this  limitation,  which  the  FDA  granted.  Otherwise,  HDE  approved  devices  are  generally  required  to  follow  the  same
requirements as PMA approved devices, including the supplement process.

Clinical studies

Clinical  studies  are  generally  required  to  support  approval  of  a  PMA  or  HDE.  Such  studies  generally  require  an  Investigational  Device
Exemption ("IDE") approval from the FDA for a specified number of patients and study sites, unless the product is deemed a non-significant risk
device  eligible  for  more  abbreviated  IDE  requirements.  Clinical  studies  are  subject  to  extensive  monitoring,  recordkeeping  and  reporting
requirements. Clinical studies must be conducted under the oversight of an IRB for the relevant clinical study sites and must comply with FDA
regulations, including those relating to current Good Clinical Practices ("cGCPs"). To conduct a clinical study, we also are required to obtain the
patients’ informed consent in form and substance that complies with both FDA requirements and state and federal privacy and human subject
protection regulations. We, the FDA or the respective IRB could suspend a clinical study at any time for various reasons, including a belief that
the  risks  to  study  subjects  outweigh  the  anticipated  benefits.  Even  if  a  study  is  completed,  the  results  of  clinical  testing  may  not  adequately
demonstrate the safety and efficacy of the device or may otherwise not be sufficient to obtain FDA approval to market the product in the U.S.

15

Post-approval studies are also typically required as a condition of PMA to reinforce the reasonable assurance of safety and effectiveness. Such
studies are conducted in the post-market setting with the approved device, often to address the long-term use of the device or other discrete
questions that may have been raised based on the clinical data from the IDE clinical study. The FDA required a post-approval registry study as
a condition of approval for Optune for recurrent GBM, which we completed.

Clinical studies involving pharmacological/immunological therapy candidates may be regulated under FDA’s drug regulations, Unless exempt,
such studies require authorization from FDA of an Investigational New Drug Application ("IND") for a specified number of patients and study
sites.  As  with  IDE  studies,  IND  studies  are  subject  to  extensive  monitoring,  recordkeeping  and  reporting  requirements,  must  be  conducted
under the oversight of an IRB, must comply with FDA drug or biologic regulations, and are required to obtain informed consent that complies
with FDA requirements and state and federal privacy and human subject protection regulations. IND clinical studies can be suspended at any
time by us, the FDA or an IRB for various reasons, including a belief that the risks to study subjects outweigh the anticipated benefits. Even if an
IND study is completed, the results of clinical testing may not be sufficient to obtain FDA approval to market the product.

Foreign approvals and CE mark

Market access, sales and marketing of medical devices outside of the U.S. are subject to foreign regulatory requirements that vary widely from
country to country. In the European Economic Area (“EEA”), for Novocure’s devices these include the requirement to obtain a CE Certificate
and to affix a CE mark to our Products. In the EEA, whether or not we have obtained FDA approval, our devices must be subject to conformity
assessment  procedure  involving  an  EEA  notified  body,  a  private  organization  accredited  by  an  EEA  member  state  to  conduct  conformity
assessment procedures under the MDR. Apart from low risk medical devices (Class I with no measuring function and which are not sterile), a
conformity  assessment  procedure  requires  the  intervention  of  a  notified  body.  The  notified  body  typically  audits  and  examines  the  device’s
technical documentation, including the clinical evaluation, and the quality system for the manufacture, design and final inspection of our devices
before issuing a CE Certificate demonstrating compliance with the relevant requirements or the quality system requirements laid down in the
relevant Annexes to the MDR. Following the issuance of this CE Certificate, we can draw up a declaration of conformity and affix the CE mark
to the devices covered by this CE Certificate. The time required to CE mark our devices or to obtain approval from other non-U.S. authorities
may be longer or shorter than that required for FDA approval. Moreover, the MDR, which became applicable on May 26, 2021, with transitional
provisions for "legacy" devices under the MDD, imposed new, stricter requirements that we must comply with in order to obtain CE Certificates
for  new  devices,  and  to  renew  the  CE  Certificates  for  our  MDD-Products  when  these  expire,  or  at  the  latest,  December  31,  2027  or  2028,
depending on the device, whichever comes first. In addition, as of May 25, 2021, in the absence of a new MRA, Switzerland is now considered
a  non-EU  “third  country”  with  respect  to  medical  devices,  meaning  that  movement  of  our  Products  bearing  a  CE  mark  from  the  EEA  to
Switzerland is subject to additional requirements. In the UK, we may continue to market and sell our Products under the CE mark until June
2023. Thereafter, our Products will be regulated under the UK Regulations.

In the EEA, before carrying out a clinical investigation with a non-CE marked device to assess its safety or performance when in accordance
with  its  intended  use,  the  study  sponsor  must  receive  a  positive  opinion  from  the  local  ethics  committee  and  approval  from  the  national
competent authority in the relevant EEA member states in which the clinical investigation will be conducted. When a CE marked medical device
is used in a clinical study in accordance with its intended use, the approval of the national competent authorities is not required for the use of
such medical device in the study. In Japan, we must obtain approvals from the Ministry of Health, Labour, and Welfare ("MHLW") to market our
devices. Each regulatory approval process outside of the U.S. includes all the risks associated with FDA regulation, as well as country-specific
regulations.

Pervasive and continuing regulation

After  a  device  is  placed  on  the  market,  numerous  regulatory  requirements  apply  depending  upon  the  country  in  which  the  device  is  being
marketed. These may include:

•

product listing and establishment registration, which helps facilitate FDA inspections and other regulatory action;

• QSR, which requires manufacturers, including third-party manufacturers, to follow stringent design, testing, control, documentation and

other quality assurance procedures during all aspects of the manufacturing process for products marketed in the U.S.;

16

•

•

labeling  regulations  and  FDA  and  equivalent  competent  authority  in  other  jurisdictions  requiring  promotion  be  truthful  and  non-
misleading and prohibiting the promotion of products for uncleared, unapproved or off-label uses;

approval of product modifications that affect the safety or effectiveness of one of our devices that has been approved or is the subject of
a CE Certificate;

• Medical Device Reporting regulations of the FDCA and medical device vigilance, which require that manufacturers comply with FDA or
equivalent competent authority requirements in other jurisdictions to report if their device may have caused or contributed to a death or
serious injury, or has malfunctioned in a way that would likely cause or contribute to a death or serious injury if the malfunction of the
device or a similar device were to recur;

•

•

•

•

•

post-approval restrictions or conditions, including post-approval study commitments;

post-market  surveillance  regulations,  which  apply  when  necessary  to  protect  the  public  health  or  to  provide  additional  safety  and
effectiveness data for the device;

the  FDA’s  and  equivalent  competent  authority’s  recall  authority,  whereby  they  can  ask,  or  under  certain  conditions  order,  device
manufacturers to recall from the market a product that is in violation of governing laws and regulations;

regulations pertaining to voluntary recalls; and

notices of corrections or removals.

Our devices could be subject to voluntary recall if we, the FDA or another applicable regulatory authority determine, for any reason, that our
devices pose a risk of injury or are otherwise defective. Moreover, the FDA and other applicable regulatory authorities can order a mandatory
recall if there is a reasonable probability that our device would cause serious adverse health consequences or death.

The FDA has broad post-market and regulatory enforcement powers. We are subject to unannounced inspections by the FDA to determine our
compliance with the QSR and other regulations and these inspections include the manufacturing facilities of our subcontractors. We are also
subject to FDA’s broad regulatory enforcement power around promotional activities. Failure by us or by our suppliers to comply with applicable
regulatory requirements can result in enforcement action by the FDA or other applicable regulatory authorities, which may result in sanctions,
including, but not limited to:

•

•

•

•

•

•

untitled letters, warning letters, fines, injunctions, consent decrees and civil penalties;

unanticipated expenditures to address or defend such actions;

customer notifications for repair, replacement and/or refunds;

recall, detention or seizure of our devices;

operating restrictions or partial suspension or total shutdown of production;

refusing or delaying our requests for approval of device candidates or a modified version of Optune;

• withdrawal of PMA/HDE approvals or suspension, variation or withdrawal of CE Certificates that have already been granted;

•

•

refusal to grant export approval for our devices; or

civil and/or criminal prosecution by the U.S. Department of Justice or other enforcement authorities outside of the U.S.

17

To  date,  our  facilities  and  those  of  our  critical  suppliers  have  been  inspected  by  several  relevant  regulatory  authorities  in  order  to  obtain
regulatory approval of our Products. No inspectional observations were identified were issued following these inspections.

Durable medical equipment accreditation and licensing and other requirements

In the U.S., we are subject to accreditation and licensing requirements as a durable medical equipment ("DME") supplier in most states and
must  meet  the  supplier  standards  of  Medicare,  Medicaid  and  other  federal  healthcare  programs.  Certain  states  require  that  DME  providers
maintain an in-state location. Although we believe we are in compliance with all applicable federal and state regulations regarding accreditation
and licensure requirements and similar requirements in other jurisdictions, if we are found to be noncompliant, we could lose our accreditation
or  licensure  in  such  states  or  our  supplier  rights  under  such  federal  healthcare  programs,  which  could  prohibit  us  from  selling  our  current  or
future devices to patients in such state or to that federal healthcare program.

Healthcare regulatory matters

In  addition  to  FDA  restrictions  on  the  marketing  of  medical  devices,  several  other  U.S.  federal  and  state  laws  have  been  applied  to  restrict
certain business practices in the healthcare industry and penalize unlawful conduct. These laws include the federal Anti-Kickback Statute, the
federal prohibition on physician self-referrals (commonly known as the "Stark Law") and the federal False Claims Act.

The  U.S.  federal  Anti-Kickback  Statute  is  a  criminal,  intent-based  statute  that  prohibits,  among  other  things,  knowingly  and  willfully  offering,
paying,  soliciting  or  receiving  any  remuneration  to  induce  or  in  return  for  purchasing,  leasing,  ordering,  recommending  or  arranging  for  the
purchase, lease, order or recommendation of any healthcare item or service that may be paid for, in whole or in part, by Medicare, Medicaid or
another federal healthcare program. Among other arrangements, this statute has been interpreted to apply to financial arrangements between
medical device manufacturers on one hand and prescribers and purchasers on the other. Although there are a number of statutory exceptions
and regulatory safe harbors that protect certain common activities from prosecution under the law, the exceptions and safe harbors are drawn
narrowly  and  practices  that  involve  the  provision  of  remuneration  intended  to  induce  ordering,  purchasing,  leasing  or  recommending  of  a
medical device may be subject to scrutiny if they do not qualify for an exception or safe harbor. In some cases, our practices may not meet all of
the technical elements for protection under a federal Anti-Kickback Statute exception or safe harbor. Similarly, as a supplier, we are also subject
to the federal beneficiary anti-inducement statute, which prohibits us from offering any remuneration to a beneficiary of Medicare or Medicaid
that is likely to influence that beneficiary’s choice of therapy, unless an exception applies. This can include, but is not limited to, the provision of
inappropriate financial assistance to purchase our Products. Recent government investigations and enforcement actions have focused on the
provision of financial assistance to patients by providers and suppliers. As noted, there are established exceptions from liability, but we cannot
guarantee that all of our practices will fall squarely within those exceptions.

As a DME supplier, we also are subject to the Stark law, which is a strict liability law that prohibits Medicare payments for certain "designated
health  services"  ("DHS")  including  DME  ordered  by  physicians  who,  personally  or  through  an  immediate  family  member,  have  an  ownership
interest in or a compensation arrangement with the furnishing DHS entity. The Stark law contains a number of specific exceptions that, if met,
permit physicians who have certain financial relationships with a DHS entity to make referrals to that entity and for that entity to bill Medicare for
such services.

The  False  Claims  Act  prohibits  any  person  from  knowingly  presenting,  or  causing  to  be  presented,  a  false  claim  for  payment  to  the  federal
government, or knowingly making, or causing to be made, a false statement to get a false claim paid. The government has pursued numerous
cases under the False Claims Act in connection with the off-label promotion of medical products and various other health care law violations.
Notably,  the  government  may  assert  that  a  claim  including  items  or  services  resulting  from  a  violation  of  the  federal  Anti-Kickback  Statute
constitutes a false or fraudulent claim for purposes of the federal civil False Claims Act.

The majority of states also have statutes or regulations similar to the federal Anti-Kickback Statute, Stark Law and False Claims Act laws, which
apply to items and services reimbursed under Medicaid and other state programs, or, in several states, that apply regardless of the payer (e.g.,
including private/commercial payors or cash-pay scenarios).

Numerous federal and state laws and regulations, including the Health Insurance Portability and Accountability Act of 1996 as amended by the
Health Information Technology for Economic and Clinical Health Act ("HITECH" and collectively "HIPAA"), govern the collection, dissemination,
use, security and privacy of individually identifiable

18

health information. We believe we are in substantial compliance with such applicable laws and regulations, including HIPAA.

HIPAA  also  includes  a  number  of  federal  criminal  provisions,  including  for  healthcare  fraud  and  for  false  statements  relating  to  healthcare
matters.  The  healthcare  fraud  provision  prohibits  knowingly  and  willfully  executing  a  scheme  to  defraud  any  healthcare  benefit  program,
including  private  third-party  payers.  The  false  statements  provision  prohibits  knowingly  and  willfully  falsifying,  concealing  or  covering  up  a
material  fact  or  making  any  materially  false,  fictitious  or  fraudulent  statement  in  connection  with  the  delivery  of  or  payment  for  healthcare
benefits,  items  or  services.  Many  states  have  similar  healthcare  fraud  laws  or  insurance  fraud  laws  that  apply  to  claims  for  healthcare
reimbursement.

Sanctions under these federal and state laws may include civil monetary penalties, exclusion of a manufacturer’s products from reimbursement
under government programs, criminal fines and imprisonment.

Legislation similar to the federal Anti-Kickback Statute, the Stark Law and False Claims Act has been adopted in foreign countries, including a
number of EU member states.

In the EU, the General Data Protection Regulation ("GDPR") has applied since May 25, 2018. The GDPR harmonizes data privacy laws and
rules for the processing of personal data, including patient and employee data, across the EU and repeals and replaces Directive 95/46/EC of
the European Parliament and of the Council of October 24, 1995, and applicable national laws. The GDPR has added a number of strict data
protection and security requirements for companies processing personal data of EU residents, including when such data is transferred outside
the EU.

In the U.S., the federal Physician Payment Sunshine Act ("Sunshine Act") requires certain manufacturers of drugs, medical devices, biologicals
or medical supplies that participate in U.S. federal health care programs to track and then report certain payments and transfers of value given
to  "Covered  Recipients."  The  term  "Covered  Recipients"  currently  includes  U.S.-licensed  physicians  and  teaching  hospitals,  and,  for  reports
submitted  on  or  after  January  1,  2022,  physician  assistants,  nurse  practitioners,  clinical  nurse  specialists,  certified  nurse  anesthetists,  and
certified nurse-midwives. The Sunshine Act requires that manufacturers collect this information on a yearly basis and then report it to Centers
for  Medicare  &  Medicaid  Services  by  the  90th  day  of  each  subsequent  year.  We  have  adopted  policies  and  codes  of  conduct  regarding  our
interactions with Covered Recipients and believe we are in material compliance with the Sunshine Act. However, our failure to adhere to these
requirements could materially adversely impact our business and financial results. Additionally, a number of states have transparency reporting
requirements similar to (and in some cases broader than) the Sunshine Act, and regulations similar to the Sunshine Act have been adopted in
foreign countries including a number of EU member states.

In addition, the U.S. Foreign Corrupt Practices Act ("FCPA") prohibits corporations and individuals from engaging in certain activities to obtain or
retain business outside the U.S. or to influence a person working in an official capacity in a foreign country. It is illegal to pay, offer to pay or
authorize the payment of anything of value to any official of another country, government staff member, political party or political candidate in an
attempt  to  obtain  or  retain  business  or  to  otherwise  influence  a  person  working  in  that  capacity.  Legislation  similar  to  the  FCPA  has  been
adopted in foreign countries, including a number of EU member states.

Human Capital Resources

As of December 31, 2022, we had 1,320 employees, compared to 1,167 employees as of December 31, 2021. We believe relations with our
employees are good.

To achieve commercial success for our Products, we believe we must continue to develop and grow our sales and marketing, patient support
and research and development teams, along with the necessary staff to support it. This need accounts for the significant increase in the number
of employees in 2021. Developing and managing a growing organization is a difficult, expensive and time consuming process. To be successful
we must:

•

•

recruit and retain adequate numbers of effective and experienced sales and marketing, patient support and research and development
personnel;

effectively train our personnel on the benefits and risks of our Products and healthcare compliance; and

• manage geographically disbursed business operations.

19

We  compete  with  other  medical  device,  pharmaceutical  and  life  sciences  companies  to  recruit,  hire,  train  and  retain  the  personnel  that  we
anticipate  we  will  need.  Because  our  current  Products  require,  and  we  anticipate  our  future  Products  will  require,  physician  training  and
education, we expect that our sales and marketing and patient support teams will continue to grow substantially as we expand our approved
indications and markets.

The ongoing COVID-19 pandemic also creates challenges to our ability to recruit and retain effective and experienced employees. In 2021, we
instituted  a  COVID-19  vaccine  mandate  for  all  employees  (subject  to  certain  exceptions).  Some  employees  chose  to  leave  our  company  in
response to this mandate and while the pandemic continues, this mandate may limit our ability to recruit new employees.

ITEM 1A.  RISK FACTORS

An  investment  in  our  ordinary  shares  involves  a  high  degree  of  risk.  Investors  and  prospective  investors  should  carefully  consider  all  of  the
information in this Annual Report on Form 10-K, including the risks and uncertainties described below. Any of the following risks could have a
material  adverse  effect  on  our  business,  prospects,  financial  condition  and  results  of  operations.  In  any  such  case,  the  trading  price  of  our
ordinary  shares  could  decline,  and  you  could  lose  all  or  part  of  your  investment.  In  assessing  these  risks,  you  should  also  refer  to  the  other
information contained in this Annual Report on Form 10-K, including our consolidated financial statements and the related notes thereto.

Risks relating to our business and our Products

Our business and prospects depend heavily on Optune, which is currently approved only for the treatment of GBM, and Optune Lua,
which  is  currently  approved  only  for  the  treatment  of  MPM.  If  we  are  unable  to  increase  sales  of  our  Products,  obtain  further
regulatory  approvals  and  commercialize  our  Products  for  the  treatment  of  additional  indications,  or  are  significantly  delayed  or
limited in doing so, our business and prospects will be materially harmed.

To date we have received FDA regulatory approval under the PMA pathway and certain approvals in other jurisdictions for the use of Optune for
the  treatment  of  adult  patients  with  newly  diagnosed  GBM  in  combination  with  certain  forms  of  chemotherapy  and  for  the  treatment  of  adult
patients with recurrent GBM as monotherapy. Optune has a CE mark affixed for the treatment of GBM in the EU and Switzerland. We have also
received FDA approval under the HDE pathway to market Optune Lua for unresectable, locally advanced or metastatic, MPM in combination
with standard chemotherapies. Optune Lua is also CE Certified for the same indication in the EU and Switzerland. However, such approvals
and maintaining the CE Certificates of Conformity, and related CE marking, of our Products, as applicable, do not guarantee future revenues for
these indications. Further, until we receive FDA and analogous approval in other jurisdictions for the use of our Products for other indications,
almost all of our revenues will derive from sales and royalties from sales of Optune for the treatment of newly diagnosed and recurrent GBM
and  Optune  Lua  for  MPM.  The  commercial  success  of  our  Products  and  our  ability  to  generate  and  maintain  revenues  from  the  sale  of  our
Products will depend on a number of factors, including:

•

•

•

•

•

•

•

•

•

•

•

•

•

our ability to develop and obtain additional regulatory approvals and further commercialize our Products for additional indications;

our ability to expand into new markets and future indications;

the acceptance of our Products by patients and the healthcare community, including physicians and third-party payers (both private and
governmental), as therapeutically effective and safe;

the accomplishment of various scientific, engineering, clinical, regulatory and other goals, which we sometimes refer to as milestones,
on our anticipated timeline;

the relative cost, safety and efficacy of alternative therapies;

our ability to obtain and maintain sufficient coverage or reimbursement by private and governmental third-party payers and to comply
with applicable health care laws and regulations;

the ability of our third-party manufacturers to manufacture our Products in sufficient quantities with acceptable quality;

our ability to provide marketing, distribution and customer support for our Products;

the presence of competitive products in our active indications;

results of future clinical studies relating to our Products or other competitor products for similar indications;

compliance with applicable laws and regulatory requirements, in particular in the EU;

the maintenance of our existing regulatory approvals; and

the consequences of any reportable adverse events involving our Products.

21

In addition, the promotion of our Products is limited to approved indications, which vary by geography. The labelling for Optune in the U.S. is
limited in certain respects (for example, it is approved specifically for glioblastomas of the supratentorial region of the brain, is indicated for use
in the treatment of newly diagnosed GBM only when used together with temozolomide, and limited to use by adults ages 22 and older), which
may limit the number of patients to whom it is prescribed. Similarly, the label for Optune Lua also contains certain limitations that may adversely
affect adoption, including the requirement in the United States (applicable to all HDE-approved devices) to display on all marketing materials
that the efficacy of the Product has not been established, as well as a limitation for use by adults ages 22 and older, and the absence of pivotal
clinical data.

Our ability to generate future revenues will also depend on achieving regulatory approval of, and eventual commercialization of, our Products
for additional indications and in additional geographies, which is not guaranteed. Our near-term prospects are substantially dependent on our
ability to obtain regulatory approvals on the timetable we have anticipated, and thereafter to further successfully commercialize our Products for
additional indications. Regulatory changes or actions in areas in which we operate or propose to operate may further affect our ability to obtain
regulatory  approvals  on  our  anticipated  timetable.  If  we  are  not  able  to  receive  such  approvals,  meet  other  anticipated  milestones,  or  further
commercialize our Products, or are significantly delayed or limited in doing so, our business and prospects will be materially harmed and we
may need to reduce expenses by delaying, reducing or curtailing the development of our Products and we may need to raise additional capital
to fund our operations, which we may not be able to obtain on favorable terms, if at all.

To date, we have generated only limited and intermittent operating profits, and we have a history of incurring substantial operating
losses.

We were founded in 2000 and have only recently and intermittently started generating limited operating profits. We have otherwise had a history
of  incurring  substantial  operating  losses.  We  anticipate  continuing  to  incur  significant  costs  associated  with  commercializing  our  Products  for
approved indications including product sales, marketing, manufacturing, and distribution expenses. We expect our research, development, and
clinical study expenses to increase in connection with our ongoing activities and as additional indications enter late-stage clinical development
and as we advance our product development. Our expenses could increase beyond expectations if, for example, we are required by the FDA,
or other regulatory agencies or similar governing bodies, to change manufacturing processes for our Products or to perform clinical, nonclinical
or other types of studies in addition to those that we currently anticipate. Our revenues are dependent, in part, upon the size of the markets in
the  jurisdictions  in  which  we  receive  regulatory  approval,  the  accepted  price  for  our  Products  and  the  ability  to  obtain  reimbursement  at  the
accepted  applicable  price.  If  the  number  of  addressable  patients  is  not  as  significant  as  we  estimate,  the  indications  approved  by  regulatory
authorities  are  narrower  than  we  expect  or  the  eligible  population  for  treatment  is  narrowed  by  competition,  regulatory  approvals,  physician
choice or treatment guidelines, we may not generate significant revenues. If we are not able to generate significant revenues, we may never be
sustainably profitable.

Our clinical studies could be delayed or otherwise adversely affected by many factors, including difficulties in enrolling patients.

Clinical testing can be costly and take many years, and the outcome is uncertain and susceptible to varying interpretations. Moreover, success
in preclinical and early clinical studies does not ensure that large-scale studies will be successful or predict final results. Acceptable results in
early  studies  may  not  be  replicable  in  later  studies.  A  number  of  companies  in  the  oncology  industry  have  suffered  significant  setbacks  in
advanced clinical studies, even after promising results in earlier studies. Negative or inconclusive results or adverse events or incidents during a
clinical study could cause the clinical study to be redone or terminated. In addition, failure to appropriately construct clinical studies could result
in high rates of adverse events or incidents, which could cause a clinical study to be suspended, redone or terminated. Our failure or the failure
of  third-party  participants  in  our  studies  to  comply  with  their  obligations  to  follow  protocols  and/or  legal  requirements  may  also  result  in  our
inability to use the affected data in our submissions to regulatory authorities.

The timely completion of clinical studies depends, among other things, on our ability to enroll a sufficient number of patients who remain in the
study until its conclusion. We may experience difficulties in patient enrollment in our clinical studies for a variety of reasons, including:

•

•

•

the severity of the disease under investigation;

the limited size and nature of the patient population;

the patient eligibility criteria defined in our protocol and other clinical study protocols;

22

•

•

•

•

•

•

•

•

•

•

•

•

the nature of the study protocol, including the attractiveness of, or the discomforts and risks associated with, the treatments received by
enrolled subjects;

difficulties and delays in clinical studies that may occur as a result of the COVID-19 pandemic;

the ability to obtain IRB approval at clinical study locations;

clinicians’ and patients’ perceptions as to the potential advantages, disadvantages and side effects of our Products in relation to other
available therapies, including any new drugs or treatments that may be approved for the indications we are pursuing;

availability of other clinical studies that exclude use of our Products;

the possibility or perception that enrolling in a Product’s clinical study may limit the patient’s ability to enroll in future clinical studies for
other therapies due to protocol restrictions;

the possibility or perception that our software is not secure enough to maintain patient privacy;

patient referral practices of physicians;

the ability to monitor patients adequately during and after treatment;

the availability of appropriate clinical study investigators, support staff, drugs and other therapeutic supplies and proximity of patients to
clinical sites;

physicians’ or our ability to obtain and maintain patient consents; and

the risk that patients enrolled in clinical studies will choose to withdraw from or otherwise not be able to complete a clinical study.

If we have difficulty enrolling and retaining a sufficient number or diversity of patients to conduct our clinical studies as planned, or encounter
other difficulties, we may need to delay, terminate or modify ongoing or planned clinical studies, any of which would have an adverse effect on
our business.

If we are unable to continue the development of an adequate sales and marketing organization or contract with third parties to assist
us, we may not be able to successfully commercialize our Products for current and future indications.

To achieve commercial success for our Products, we must continue to compliantly develop and grow our sales and marketing organization and,
as necessary, enter into sales and distribution relationships with third parties to market and sell our Products. Developing and managing a sales
and marketing organization is a difficult, expensive and time consuming process. We may not be able to successfully develop adequate sales
and  marketing  capabilities  to  achieve  our  growth  objectives.  We  compete  with  other  medical  device,  pharmaceutical  and  life  sciences
companies to recruit, hire, train and retain the sales and marketing personnel that we anticipate we will need, and the nature of our Products
may make it more difficult to compete for sales and marketing personnel. In addition, because our current Products require, and we anticipate
our future Products will require, physician training and education, our sales and marketing organization may need to grow substantially as we
expand our approved indications and markets. As a consequence, our expenses associated with building up and maintaining our sales force
and marketing capabilities may be disproportionate to the revenues we may be able to generate on sales of our Products.

If we are unable to establish adequate sales and marketing capabilities or successful sales and distribution relationships, we may fail to realize
the full revenue potential of our Products for current and future indications, and we may not be able to achieve the necessary growth in a cost-
effective  manner  or  realize  a  positive  return  on  our  investment.  In  our  current  and  future  sales  and  distribution  agreements  with  other
companies, we generally do not and may not have control over the resources or degree of effort that any of these third parties may devote to
our Products, and if they fail to devote sufficient time and resources to the marketing of our Products, or if their performance is substandard, our
revenues may be adversely affected.

23

The success of our business may be dependent on the actions of our collaborative partners.

Our  global  business  strategy  includes,  in  part,  the  consummation  of  collaborative  arrangements  with  companies  who  will  support  the
development  and  commercialization  of  our  Products  and  technology.  For  example,  we  have  exclusively  licensed  rights  to  commercialize  our
Products in the field of oncology in Greater China to Zai pursuant to an agreement that also establishes a development partnership for Tumor
Treating Fields (“TTFields”) in multiple solid tumor indications. Zai is responsible for the development and commercialization of our Products in
Greater China at its sole cost with certain assistance from us. We have also entered into several clinical collaborations with third parties to test
our Products and technology together with other products and technologies.

When we collaborate with a third party for development and commercialization of a Product in a particular territory, we can expect to relinquish
some or all of the control over the future success of that Product to the third party in that territory. In addition, our collaborative partners may
have  the  right  to  abandon  research  or  development  projects  and  terminate  applicable  agreements,  including  payment  obligations,  prior  to  or
upon  the  expiration  of  the  agreed-upon  terms.  We  may  not  be  successful  in  establishing  or  maintaining  collaborative  arrangements  on
acceptable terms or at all, collaborative partners may terminate funding before completion of projects, our Products may not achieve the criteria
for milestone payments, our collaborative arrangements may not result in successful product commercialization, our Products may not receive
acceptable  pricing  and  we  may  not  derive  any  revenue  from  such  arrangements.  Additionally,  our  collaborators  may  not  perform  their
obligations as expected or in compliance with study protocols or applicable laws. Our collaborators may also be subject to additional risks in
their  particular  territories,  such  as  a  lack  of  intellectual  property  protections  and/or  enforcement  or  the  possibility  of  nationalization.  Acts  or
omissions by collaborators may disqualify study data for use in regulatory submissions and/or create liability for us in the jurisdictions in which
we  operate.  Any  disagreements  with  collaborators,  including  disagreements  over  proprietary  rights,  contract  interpretation  or  the  preferred
course of development or commercialization, might cause delays or termination of the research, development or commercialization of Products,
might lead to additional responsibilities for us with respect to developing or commercializing Products, or might result in litigation or arbitration,
any of which would be time-consuming and expensive. To the extent that we are not able to develop and maintain collaborative arrangements,
we would need to devote substantial capital to undertake development and commercialization activities on our own in order to further expand
our global reach, and we may be forced to limit the territories in which we commercialize our Products.

We may not be successful in achieving market acceptance of our Products by healthcare professionals, patients and/or third-party
payers  in  the  timeframes  we  anticipate,  or  at  all,  which  could  have  a  material  adverse  effect  on  our  business,  prospects,  financial
condition and results of operations.

Our business model is predicated on achieving market acceptance of our Products as a monotherapy or in combination with well-established
cancer treatment modalities like surgery, radiation, pharmacological and immunocologic therapies. We may not achieve market acceptance of
our Products for current or future indications within the timeframes we have anticipated, or at all, for a number of different reasons, including the
following factors:

•

•

•

•

•

it  may  be  difficult  to  gain  broad  acceptance  of  our  Products  because  they  are  new  technologies  and  involve  a  novel  mechanism  of
action and, as such, physicians may be reluctant to prescribe our Products without prior experience or additional data or training;

physicians may be reluctant to prescribe our Products due to their perception that the supporting clinical study designs have limitations,
as they are, for example, unblinded;

physicians at large academic universities and medical centers may prefer to enroll patients into clinical studies instead of prescribing
our Products;

it  may  be  difficult  to  gain  broad  acceptance  at  community  hospitals  where  the  number  of  patients  seeking  treatment  may  be  more
limited than at larger medical centers, and such community hospitals may not be willing to invest in the resources necessary for their
physicians to become trained to use our Products, which could lead to reluctance to prescribe our Products;

patients may be reluctant to use our Products for various reasons, including a perception that the treatment is untested or difficult to use
(for example, they will need to shave the areas on their bodies where the arrays are applied) or a perception that our software is not
secure;

24

•

•

our  Products  may  have  side  effects  (for  example,  dermatitis  where  the  arrays  are  placed)  and  our  Products  cannot  be  worn  in  all
circumstances (for example, they cannot get wet and are difficult to wear in high temperatures); and

the price of our Products includes a monthly fee for use of the device and therefore, as the duration of the treatment course increases,
the overall price will increase correspondingly and, when used in combination with other treatments, the overall cost of treatment will be
greater than using a single type of treatment.

In particular, our Products may not achieve market acceptance for current or future indications because of the following additional factors:

•

•

•

•

•

•

achieving patient acceptance could be difficult because we are targeting devastating diseases with poor prognoses, and not all patients
with  potentially  short  lifespans  are  willing  to  comply  with  requirements  of  treatment  with  our  Products,  such  as  the  need  to  use  our
Products for at least 18 hours per day, carrying around a device and shaving the area where the arrays are worn, and other patients
may forego our Products for financial, privacy, cosmetic, visibility or mobility reasons;

achieving  patient  compliance  is  difficult  because  the  recommended  use  of  our  currently  marketed  Products  is  throughout  the  day,
requiring patients to wear the device nearly continuously, which to some extent restricts physical mobility because the battery must be
frequently exchanged and recharged, and the patient or a caregiver must ensure that it remains continuously operable and this may
also impact the pool of patients to whom physicians may be willing to prescribe our Products;

certain patients are contraindicated to using our Products due to a variety of factors, including, but not limited to, those who have an
active implanted medical device, those who have a skull defect, and those who are sensitive to conductive hydrogels;

there are certain perceived limitations to our study designs or data obtained from our clinical studies;

efficacy may also be limited in instances where patients take a break from the device when experiencing skin rashes, while bathing or
swimming (because our Products should not get wet), or while traveling; and

patients may decline therapy or prescribers may be unwilling to prescribe our Products due to certain adverse events reported in clinical
studies  by  patients  treated  with  our  Products  as  monotherapy  include  medical  device  site  reaction,  headache,  malaise,  muscle
twitching, fall and skin ulcer; additional adverse events reported in clinical studies by patients treated with our Products in combination
with  chemotherapies  in  addition  to  the  above,  were  thrombocytopenia,  nausea,  constipation,  vomiting,  fatigue  and  other  side  effects
consistent with treatment with chemotherapies.

In addition, even if we are successful in achieving market acceptance of our Products for GBM or MPM, we may be unsuccessful in achieving
market acceptance of our Products for other indications, such as brain metastases, NSCLC, pancreatic cancer, ovarian cancer and other solid
tumor cancers, because certain radiation, chemotherapies and/or systemic medical therapies may become or remain the preferred standard of
care for these indications.

There may be other factors that are presently unknown to us that also may negatively impact our ability to achieve market acceptance of our
Products. If we do not achieve market acceptance of our Products in the timeframes we anticipate, or are unable to achieve market acceptance
at all, our business, prospects, financial condition and results of operations could be materially adversely affected.

Failure to secure and maintain adequate coverage and reimbursement from third-party payers could adversely affect acceptance of
our Products and reduce our revenues.

We  expect  that  the  vast  majority  of  our  revenues  will  come  from  third-party  payers  either  directly  to  us  in  markets  where  we  provide  our
Products  or  plan  to  provide  our  device  candidates  to  patients  or  indirectly  via  payments  made  to  hospitals  or  other  entities  providing  our
Products or which may in the future provide our device candidates to patients.

25

In the U.S., private payers cover the largest segment of the population, with the remainder either uninsured or covered by governmental payers.
The  majority  of  the  third-party  payers  outside  the  U.S.  are  government  agencies,  government  sponsored  entities  or  other  payers  operating
under significant regulatory requirements from national or regional governments.

Third-party  payers  may  decline  to  cover  and  reimburse  certain  procedures,  supplies  or  services.  Additionally,  some  third-party  payers  may
decline to cover and reimburse our Products for a particular patient even if the payer has a favorable coverage policy addressing our Products
or previously approved reimbursement for our Products. Additionally, private and government payers may consider the cost of a treatment in
approving coverage or in setting reimbursement for the treatment.

Private  and  government  payers  around  the  world  are  increasingly  challenging  the  prices  charged  for  medical  products  and  services.
Additionally, the containment of healthcare costs has become a priority of governments around the world. Adoption of additional price controls
and cost-containment measures, and adoption of more restrictive policies in jurisdictions with existing controls and measures by both private
and public payers, could further limit our revenues and operating results. If third-party payers do not consider our Products or the combination of
our  Products  with  additional  treatments  to  be  cost-justified  under  a  required  cost-testing  model,  they  may  not  cover  our  Products  for  their
populations or, if they do, the level of reimbursement may not be sufficient to allow us to sell our Products on a profitable basis.

Reimbursement  for  the  treatment  of  patients  with  medical  devices  around  the  world  is  governed  by  complex  mechanisms  established  on  a
national or sub-national level in each country. These mechanisms vary widely among countries, can be informal, somewhat unpredictable, and
evolve  constantly,  reflecting  the  efforts  of  these  countries  to  reduce  public  spending  on  healthcare.  As  a  result,  obtaining  and  maintaining
reimbursement for the treatment of patients with medical devices has become more challenging globally. We cannot guarantee that the use of
our Products will receive reimbursement approvals and cannot guarantee that our existing reimbursement approvals will be maintained in any
country.

We provide financial assistance to certain patients in certain markets who qualify based on established financial and other criteria. Primarily, we
provide  financial  assistance  to  patients  where  we  have  or  are  actively  pursuing  coverage  and  reimbursement.  This  financial  assistance  is
intended  to  defray  out-of-pocket  costs  for  our  Products  for  patients  who  begin  treatment  but  who  are  unable  to  pay  for  the  costs  of  their
treatment  not  covered  by  insurance.  Our  costs  associated  with  this  program  could  increase  if  payers  increase  the  cost-sharing  burden  of
patients or we do not obtain coverage and reimbursement and we elect to continue providing financial assistance in those markets. Additionally
we provide charitable donations to foundations that can then provide financial assistance to those receiving health care coverage from federal
or  state  funded  programs.  Enforcement  actions  and  changes  to  government  regulations  related  to  manufacturer-sponsored  and  independent
charitable patient assistance programs could reduce our ability to support patients financially in the future.

Our  failure  to  secure  or  maintain  adequate  coverage  or  reimbursement  for  our  Products  by  third-party  payers  in  the  U.S.  or  in  the  other
jurisdictions in which we market our Products could have a material adverse effect on our business, revenues and results of operations and
cause our stock price to decline.

We may not be successful in securing and maintaining reimbursement codes necessary to facilitate accurate and timely billing for
our Products or physician services attendant to our Products.

Third-party payers, healthcare systems, government agencies or other groups often issue reimbursement codes to facilitate billing for products
and physician services used in the delivery of healthcare. Within the U.S., the billing codes most directly related to our Products are contained
in  the  Healthcare  Common  Procedure  Coding  System  ("HCPCS  code  set").  The  HCPCS  code  set  contains  Level  I  codes  that  describe
physician services, also known as Common Procedural Terminology codes ("CPT codes") and Level II codes that primarily describe products.
CMS is responsible for issuing the HCPCS Level II codes. The American Medical Association issues HCPCS Level I codes.

We have secured unique HCPCS Level II codes that describe Optune and we are able to use these codes in the U.S. to bill third-party payers.
Loss of these codes or any alteration in the reimbursement amounts attached to these codes would materially impact our operating results. We
do not have a unique HCPCS Level II code for Optune Lua at this time.

No CPT codes currently exist to describe physician services related to the delivery of therapy using our Products. We may not be able to secure
CPT codes for physician services related to our Products. Our future revenues and results may be affected by the absence of CPT codes, as
physicians may be less likely to prescribe the therapy when there is no certainty that adequate reimbursement will be available for the time,
effort, skill, practice expense and malpractice costs required to provide the therapy to patients.

26

Outside the U.S., but excluding Germany and Japan, we have not secured codes to describe our Products or to document physician services
related  to  the  delivery  of  therapy  using  our  Products.  The  failure  to  obtain  and  maintain  these  codes  could  affect  the  future  growth  of  our
business.

There  is  no  assurance  that  Medicare  or  the  Medicare  Administrative  Contractors  will  provide,  or  continue  to  provide,  coverage  or
adequate payment rates for our Products.

We anticipate that a significant portion of patients using our Products will be beneficiaries under the Medicare fee-for-service program. Failure to
secure or maintain coverage or maintain adequate reimbursement from Medicare would reduce our revenues and may also affect the coverage
and reimbursement decisions of other third-party payers in the U.S. and elsewhere.

Medicare classifies Optune as durable medical equipment ("DME"). Medicare has the authority to issue national coverage determinations or to
defer coverage decisions to its regional Medicare Administrative Contractors ("MACs"). The fact that only two MACs administer the entire DME
program  may  negatively  affect  our  ability  to  petition  individual  medical  policy  decision-makers  at  the  MACs  for  coverage.  The  absence  of  a
positive coverage determination or a future restriction to existing coverage from Medicare or the DME MACs would materially affect our future
revenues.

Additionally,  Medicare  has  the  authority  to  publish  the  reimbursement  amounts  for  DME  products.  Medicare  has  published  a  reimbursement
amount for Optune that falls below the median reimbursement that we have established with non-Medicare payers. Medicare may in the future
publish  reimbursement  amounts  for  our  Products  that  do  not  reflect  then-current  prices  for  our  Products  or  Medicare  may  decrease  existing
reimbursement amounts published for our Products. Medicare fee schedules are frequently referenced by private payers in the U.S. and around
the world. Medicare's publication of reimbursement amounts for our Products that are below our Products’ established prices could materially
reduce our revenues and operating results with respect to non-Medicare payers in the U.S. and our other active markets.

Medicare has assigned the billing codes describing Optune to the DME category for products that require frequent and substantial servicing.
DME items in this billing category are billed monthly and payment is not capped after a time period. If Medicare revises its payment category
classifications for our Products, this action could materially reduce our revenues and operating results.

CMS requires prior authorization for certain DME items. Claims for such items that did not receive prior authorization before they were furnished
to a beneficiary will be automatically denied. In the event Medicare adds one of our Products to the list of items requiring prior authorization, our
ability  to  bill  and  secure  reimbursement  for  patients  who  would  otherwise  be  covered  to  use  our  Product  under  the  Medicare  fee-for-service
program may be reduced.

The Medicare fee-for-service program has denied coverage for all claims prior to the September 1, 2019 effective date for the DME MAC LCD,
which provides coverage for Optune for the treatment of newly diagnosed GBM subject to certain conditions and restrictions. We expect that
Medicare  will  continue  to  deny  essentially  all  claims  that  do  not  meet  the  coverage  policy  terms.  Although  we  are  actively  appealing  these
coverage  denials,  we  are  unable  to  bill  the  vast  majority  of  our  existing  Medicare  fee-for-service  patients  for  amounts  not  paid  by  Medicare.
Therefore, we are absorbing and may continue to absorb the costs of treatment for amounts not paid by Medicare.

We  appeal  Medicare  coverage  denials  through  the  Medicare  appeals  process:  redetermination  by  a  MAC,  reconsideration  by  a  Qualified
Independent  Contractor,  hearing  before  an  Administrative  Law  Judge  (“ALJ”)  at  the  Office  of  Medicare  Hearings  and  Appeals,  review  by  the
Medicare Appeals Council, and judicial review in U.S. District Court. Currently, there is a considerable backlog of appeals at the ALJ level and
there  are  significant  delays  in  the  assignment  of  ALJ  cases.  We  cannot  provide  any  assurance  that  our  outstanding  ALJ  appeals  will  be
favorably  decided.  Further,  we  anticipate  that,  even  if  we  are  successful  in  winning  our  appeals,  we  will  experience  a  significant  delay  in
securing reimbursement for Medicare patients when Medicare’s DME MACs deny coverage for patients who start therapy.

While  we  have  obtained  Medicare  coverage  for  our  existing  Products,  we  cannot  provide  any  assurance  that  we  can  access  transitional,
expedited,  or  expanded  Medicare  coverage  for  our  future  Products.  CMS  is  expected  to  issue  rules  regarding  coverage  of  emerging
technologies; however, no specific information is available about the content of the expected rules and we cannot provide any assurance that
any new rules regarding emerging technologies would be applicable to our future Products.

27

We depend on single-source suppliers for some of our components. The loss of these suppliers could prevent or delay shipments of
our Products, delay our clinical studies or otherwise adversely affect our business.

In  certain  jurisdictions,  we  source  some  of  the  components  of  our  Products  from  only  a  single  vendor.  If  any  one  of  these  single-source
suppliers were to fail to continue to provide components to us on a timely basis, or at all, our business and reputation could be harmed. Our
policy is to seek and maintain second-source suppliers, but we can provide no assurance that we will secure or maintain such suppliers. We
have developed or are in the process of developing and obtaining regulatory approval for second sources for components in all jurisdictions.
Various steps must be taken before securing these suppliers, including qualifying these suppliers in accordance with regulatory requirements,
but  we  may  never  receive  such  approvals.  The  risks  associated  with  the  failure  of  our  suppliers  to  comply  with  strictly  enforced  regulatory
requirements as described below are exacerbated by our dependence on single-source suppliers.

If we experience any deficiency in the quality of, delay in or loss of availability of any components supplied to us by third-party suppliers, or if we
switch  suppliers  or  components,  we  may  face  additional  regulatory  delays  and  the  manufacture  and  delivery  of  our  Products  would  be
interrupted  for  an  extended  period  of  time,  which  could  materially  adversely  affect  our  business,  prospects,  financial  condition  and  results  of
operations.  If  we  are  required  to  obtain  prior  regulatory  approval  from  the  FDA  or  regulatory  authorities  or  similar  governing  bodies  in  other
jurisdictions  or  to  conduct  a  new  conformity  assessment  procedure  and  obtain  new  CE  Certificates  of  Conformity  in  the  EU  to  use  different
suppliers or components for our Products, regulatory approval or the CE Certificates of Conformity for our Products may not be received on a
timely basis, or at all, which would have a material adverse effect on our business, prospects, financial condition and results of operations.

Quality  control  problems  with  respect  to  devices  and  components  supplied  by  third-party  suppliers  could  have  a  material  adverse
effect on our reputation, our clinical studies or the commercialization of our Products and, as a result, a material adverse effect on
our business, prospects, financial condition and results of operations.

Our Products, which are manufactured by third parties, are highly technical and are required to meet exacting specifications. Any quality control
problems that we experience with respect to the devices and components supplied by third-party suppliers could have a material adverse effect
on our reputation, our attempts to complete our clinical studies, our operating expenses or the commercialization of our Products. The failure of
our suppliers to comply with strictly enforced regulatory requirements could expose us to regulatory action, including warning letters, product
recalls, suspension or termination of distribution, product seizures or civil penalties. If we experience any delay in the receipt or deficiency in the
quality of products supplied to us by third-party suppliers, or if we have to switch to replacement suppliers, we may face additional regulatory
delays and the manufacture and delivery of our Products would be interrupted for an extended period of time, which would materially adversely
affect our business, prospects, financial condition and results of operations.

If the third parties on which we rely to conduct our preclinical and clinical studies and to assist us with research and development do
not  perform  as  contractually  required  or  expected,  we  may  not  be  able  to  obtain  regulatory  approvals  for  or  commercialize  our
Products.

We do not have the ability to independently conduct certain of our preclinical and development activities or any of our clinical studies for our
Products; therefore, we must rely on third parties, such as contract research organizations, medical institutions, clinical investigators, contract
laboratories and collaborative partners, to conduct such studies. We and these third parties are required to comply with current good clinical
practices ("cGCPs"), which are regulations and guidelines enforced by the FDA under the medical device Quality System Regulation ("QSR")
and comparable regulatory authorities in other jurisdictions for clinical development. We and these third parties are also required to comply with
current good laboratory practices ("cGLPs"), which are regulations and guidelines enforced by the FDA and comparable regulatory authorities in
other jurisdictions for nonclinical laboratory studies. If we or any of these third parties fail to comply with applicable cGLP and cGCP regulations,
the  data  generated  in  our  nonclinical  studies  and  clinical  studies  may  be  deemed  unreliable  and  the  FDA  or  regulatory  authorities  in  other
jurisdictions  may  require  us  to  perform  additional  nonclinical  or  clinical  studies  before  approving  our  applications.  We  cannot  be  certain  that,
upon inspection or review of our data, such regulatory authorities will determine that any of our nonclinical studies or clinical studies comply with
the applicable cGLP or cGCP regulations.

Additionally, any third parties conducting our preclinical, clinical and other development programs are not and will not be our employees and,
except for remedies available to us under our agreements with such third parties, we

28

cannot control whether or not they devote sufficient time and resources to our ongoing preclinical, clinical and other development programs. If
these  third  parties  do  not  successfully  carry  out  their  contractual  duties  or  regulatory  obligations  or  meet  expected  deadlines,  if  these  third
parties  need  to  be  replaced  or  if  the  quality  or  accuracy  of  the  data  they  obtain  is  compromised  due  to  the  failure  to  adhere  to  our  clinical
protocols or regulatory requirements or for other reasons, our development activities or clinical studies may be extended, delayed, suspended
or terminated, and we may not be able to obtain regulatory approval for our Products or successfully commercialize our Products on a timely
basis, if at all, and our business, prospects and results of operations may be adversely affected.

Continued testing of our Products may not yield successful results and could reveal currently unknown aspects or safety hazards
associated with our Products.

Our research and development programs are designed to test the safety and efficacy of our Products and TTFields through extensive preclinical
and  clinical  testing.  Even  if  our  ongoing  and  future  preclinical  and  clinical  studies  are  completed  as  planned,  we  cannot  be  certain  that  their
results will support our claims or that the FDA and other regulatory authorities will agree with our conclusions. Success in preclinical studies and
early clinical studies does not ensure that later clinical studies will be successful, and we cannot be sure that the later studies will replicate the
results  of  prior  studies  and  preclinical  studies.  The  clinical  study  process  may  fail  to  demonstrate  that  our  device  candidates  are  safe  and
effective for the proposed indicated uses, which could cause us to abandon a device candidate and may delay development of others. It is also
possible that patients enrolled in clinical studies will experience adverse side effects that have not been previously observed. In addition, our
preclinical and clinical studies for our device candidates involve a relatively small patient population and, as a result, these studies may not be
indicative of future results.

We  may  experience  numerous  unforeseen  events  during,  or  as  a  result  of,  the  testing  process  that  could  delay  or  prevent  further
commercialization of our Products, including the following:

•

•

•

Preclinical  and  clinical  testing  for  our  Products  may  not  produce  the  desired  effect,  may  be  inconclusive  or  may  not  be  predictive  of
safety or efficacy results obtained in future clinical studies, following long-term use or in much larger populations;

unanticipated adverse events or other side effects that are not currently known may occur during our clinical studies that may preclude
additional regulatory approval or result in additional limitations to commercial use if approved; and

the data collected from our clinical studies may not reach statistical significance or otherwise not be sufficient to support FDA or other
regulatory approval.

If unacceptable side effects arise in the development of our Products for future indications, we could suspend or terminate our clinical studies or
the FDA or other regulatory authorities could order us to cease clinical studies or deny approval of our device candidates for any or all targeted
indications,  narrow  the  approved  indications  for  use  or  otherwise  require  restrictive  product  labeling  or  marketing  or  require  further  clinical
studies,  which  may  be  time-consuming  and  expensive  and  may  not  produce  results  supporting  FDA  or  other  regulatory  approval  of  our
Products in a specific indication. Treatment-related side effects could also affect patient recruitment or the ability of enrolled patients to complete
the study or result in potential product liability claims. In addition, these side effects may not be appropriately recognized or managed by the
treating medical staff. We expect to have a need to train medical personnel using our device candidates to understand the side effect profiles for
our clinical studies and upon any commercialization of our Products for future indications. Inadequate training in recognizing or managing the
potential side effects of our Products could result in patient injury or death. Any of these occurrences may harm our business, prospects and
financial condition significantly.

Any delay or termination of our clinical studies will delay the filing of submissions for regulatory approvals of our Products and ultimately our
ability to commercialize our Products and generate revenues. Furthermore, we may abandon our Products for indications that we previously
believed to be promising. Over time, we expect to make modifications to our Products that are designed to improve efficacy, reduce side effects,
enhance  the  user  experience  and  other  purposes.  It  is  possible  that  our  patients  will  not  accept  these  developments  or  see  them  as
improvements, necessitating abandoning the development or spending additional development efforts to refine the modification. Any of these
events could have a material adverse effect on our business, prospects, financial condition and results of operations and cause our stock price
to decline.

29

We face competition from numerous competitors, which may make it more difficult for us to achieve significant market penetration
and which may allow our competitors to develop additional oncology treatments to compete with our Products.

The oncology market is intensely competitive, subject to rapid change and significantly affected by new product introductions and other market
activities  of  industry  participants.  Our  Products  primarily  compete  with  radiation  and  pharmacological  therapies.  We  may  face  additional
competition as advancements are made in the field of anti-cancer therapies and as we enter additional oncological markets. To date, we have
conducted clinical studies where our Products are used together with a certain subset of other anti-cancer therapies. Many of our competitors
are large, well-capitalized companies with significantly greater market share and resources than we have. As a consequence, they are able to
spend more aggressively on product development, marketing, sales and other initiatives than we can. Many of these competitors could have:

•

•

•

•

significantly greater name recognition and experience;

established  distribution  networks  and/or  relationships  with  government  agencies,  healthcare  professionals,  patients  and  third-party
payers;

additional product lines, and the ability to offer rebates or bundle products to offer higher discounts or more competitive pricing or other
incentives to gain a competitive advantage; and

greater financial and human resources for research and development, sales and marketing, patent litigation and/or acquisitions.

Although we believe our Products represent a treatment modality that can be used together with other cancer treatment modalities, our current
and future competitors may at any time develop additional drugs, biologics or devices for the treatment of GBM, MPM, or other solid tumors that
could be more effective from a therapeutic or cost-basis perspective than using our Products. In our currently-approved indications, if current or
future competitors develop a product that proves to be superior or comparable to our Products, our revenues may decline. In addition, some of
our  competitors  may  compete  by  lowering  the  price  of  their  cancer  treatments.  If  these  competitors’  products  were  to  gain  acceptance  by
healthcare professionals, patients or third-party payers, a downward pressure on prices could result. If prices were to fall, we may not be able to
improve our gross margins or sales growth sufficiently to be sustainably profitable. For future indications, other companies could view us as a
competitor and attempt to block our market entry or otherwise hinder our Product growth in a market. We are aware of third parties in the United
States and China developing devices and filing for intellectual property protection related to TTFields, which, if approved, may directly compete
with  our  Products.  Competitors  could  also  pursue  lawsuits  to  invalidate  our  patents  or  develop  alternative  technologies  for  the  application  of
TTFields into a patient that we did not foresee or protect.

As we expand, we may experience difficulties managing our growth.

Our anticipated growth will place a significant strain on our management and on our operational and financial resources and systems. We could
face  challenges  inherent  in  efficiently  managing  a  more  complex  business  with  an  increased  number  of  employees  over  large  geographic
distances,  including  the  need  to  implement  appropriate  systems,  policies,  benefits  and  compliance  programs.  Failure  to  manage  our  growth
effectively  could  materially  adversely  affect  our  business.  Additionally,  our  anticipated  growth  will  increase  the  demands  placed  on  our  third-
party suppliers, resulting in an increased need to carefully monitor the available supply of components and services and to scale up our quality
assurance programs. There is no guarantee that our suppliers will be able to support our anticipated growth. Any failure by us to manage our
growth effectively could have an adverse effect on our ability to achieve our development and commercialization goals.

Because of the specialized nature of our business, the termination of relationships with our key employees, consultants and advisors
may  prevent  us  from  successfully  operating  our  business,  including  developing  our  Products,  conducting  clinical  studies,
commercializing our Products and obtaining any necessary financing.

We  are  highly  dependent  on  the  members  of  our  executive  team,  the  loss  of  whose  services  may  adversely  impact  the  achievement  of  our
objectives. While we have entered into employment agreements with each of our key executives, any of them could leave our employment at
any time. We do not have "key person" insurance on any of our employees. The loss of the services of one or more of our current employees
might impede the achievement of our business objectives.

30

The competition for qualified personnel in the oncology and medical device fields is intense, and we rely heavily on our ability to attract and
retain qualified scientific, technical and managerial personnel. Our future success depends upon our ability to attract, retain and motivate highly
skilled employees. In order to commercialize our Products successfully, we will be required to expand our workforce, particularly in the areas of
research and development and clinical studies, sales and marketing and supply chain management. These activities will require the addition of
new  personnel  and  the  development  of  additional  expertise  by  existing  management  personnel.  We  face  intense  competition  for  qualified
individuals  from  numerous  pharmaceutical,  biopharmaceutical  and  biotechnology  companies,  as  well  as  academic  and  other  research
institutions. We may not be able to attract and retain these individuals on acceptable terms or at all. Failure to do so could materially harm our
business.

Product liability suits, whether or not meritorious, could be brought against us due to alleged defective devices or for the misuse of
our Products, which could result in expensive and time-consuming litigation, payment of substantial damages and/or expenses and
an increase in our insurance rates.

If our current or future devices are defectively designed or manufactured, contain defective components or are misused, or if someone claims
any of the foregoing, whether or not meritorious, we may become subject to substantial and costly litigation. For example, we may be sued if
our Products cause or are perceived to cause injury or are found to be otherwise unsuitable during clinical testing, manufacturing, marketing or
sale. This may occur if our Products are misused or damaged, have a sudden failure or malfunction (including with respect to safety features) or
are  otherwise  impaired  due  to  wear  and  tear.  Even  absent  a  product  liability  suit,  malfunctions  of  our  Products  or  misuse  by  physicians  or
patients would need to be remedied swiftly in order to maintain continuous use and ensure efficacy of our Products.

Any product liability claims may include allegations of defects in manufacturing, defects in design, a failure to warn of dangers inherent in the
device, negligence, strict liability or a breach of warranties. Claims could also be asserted under state consumer protection acts. If we cannot
successfully defend ourselves against product liability claims, we may incur substantial liabilities or be required to limit commercialization of our
Products. Even successful defense may require significant financial and management resources. Regardless of the merits or eventual outcome,
liability claims may result in:

•

•

decreased demand for our Products;

injury to our reputation;

• withdrawal of clinical study participants and inability to continue clinical studies;

•

•

•

•

•

•

•

•

•

initiation of investigations by regulators;

costs to prepare for and defend the related litigation;

a diversion of management’s time and our resources;

substantial monetary awards to study participants or patients;

product recalls, withdrawals or labeling, marketing or promotional restrictions;

loss of revenues;

exhaustion of any available insurance and our capital resources;

the inability to commercialize any device candidate; and

a decline in our share price.

Product  liability  claims  could  divert  management’s  attention  from  our  core  business,  be  expensive  to  defend  and  result  in  sizable  damage
awards against us. We may not have sufficient insurance coverage for all claims. Any product liability claims brought against us, with or without
merit,  could  increase  our  product  liability  insurance  rates  or  prevent  us  from  securing  continuing  coverage,  could  harm  our  reputation  in  the
industry and could reduce revenues. Product liability claims in excess of our insurance coverage would be paid out of cash reserves, if any,
which could have a material adverse effect on our business, prospects, financial condition and results of operations and cause our stock price
to  decline.  Even  if  our  agreements  with  our  third-party  manufacturers  and  suppliers  entitle  us  to  indemnification  against  losses,  such
indemnification may not be available or adequate should any claim arise.

Other future litigation and regulatory actions could have a material adverse impact on the Company.

From time to time, we may be subject to litigation and other legal and regulatory proceedings relating to our business or investigations or other
actions by governmental agencies, including as described in Part I, Item 3 "Legal

31

Proceedings" of this Annual Report on Form 10-K. No assurances can be given that the results of these or new matters will be favorable to us.
An  adverse  resolution  of  lawsuits,  arbitrations,  investigations  or  other  proceedings  or  actions  could  have  a  material  adverse  effect  on  our
financial  condition  and  results  of  operations,  including  as  a  result  of  non-monetary  remedies.  Defending  ourselves  in  these  matters  may  be
time-consuming,  expensive  and  disruptive  to  normal  business  operations  and  may  result  in  significant  expense  and  a  diversion  of
management’s  time  and  attention  from  the  operation  of  our  business,  which  could  impede  our  ability  to  achieve  our  business  objectives.
Additionally, any amount that we may be required to pay to satisfy a judgment, settlement, fine or penalty may not be covered by insurance.
Subject  to  the  Jersey  Companies  Law,  our  articles  of  association  permit  us  to  indemnify  any  director  against  any  liability,  to  purchase  and
maintain  insurance  against  any  liability  for  any  director  and  to  provide  any  director  with  funds  (whether  by  loan  or  otherwise)  to  meet
expenditures  incurred  or  to  be  incurred  by  such  director  in  defending  any  criminal,  regulatory  or  civil  proceedings  or  in  connection  with  an
application  for  relief  (or  to  enable  any  such  director  to  avoid  incurring  such  expenditure).  In  addition,  we  have  entered  into  indemnification
agreements with each of our directors and officers to indemnify them against certain liabilities and expenses arising from their being a director
or officer to the maximum extent permitted by Jersey law. In the event we are required to make such payments to our directors and officers,
there can be no assurance that any of these payments will not be material.

Global economic, political and industry conditions constantly change and unfavorable conditions may have a material adverse effect
on our business and results of operations.

We are a global company with worldwide operations. Volatile economic, political and market conditions, such as political or economic instability,
civil  unrest,  trade  sanctions,  majority  hostilities  or  acts  of  terrorism  in  the  regions  in  which  we  operate  may  have  a  negative  impact  on  our
operating  results  and  our  ability  to  achieve  our  business  objectives.  We  may  not  have  insight  into  economic  and  political  trends  that  could
emerge  and  negatively  affect  our  business.  In  addition,  significant  or  volatile  changes  in  exchange  rates  between  the  U.S.  dollar  and  other
currencies may have a material adverse impact upon our liquidity, revenues, costs and operating results.

In particular, we have research facilities located in Israel, and certain key suppliers manufacture their goods in Israel. Due to the high-conflict
nature of this area, Israel could be subject to additional political, economic and military confines, which could result in a material adverse effect
on  our  operations.  Parties  with  whom  we  do  business  have  sometimes  declined  to  travel  to  Israel  during  periods  of  heightened  unrest  or
tension,  forcing  us  to  make  alternative  arrangements  when  necessary.  In  addition,  the  political  and  security  situation  in  Israel  may  result  in
parties with whom we have agreements involving performance in Israel claiming that they are not obligated to perform their commitments under
those agreements pursuant to force majeure provisions in the agreements.

Additionally,  natural  disasters  and  public  health  emergencies,  such  as  extreme  weather  events  and  the  COVID-19  pandemic,  could  have  a
significant  adverse  effect  on  our  business,  including  interruption  of  our  commercial  and  clinical  operations,  supply  chain  disruption,
endangerment of our personnel, fewer patient visits, increased patient drop-out rates, delays in recruitment of new patients, and other delays or
losses of materials and results.

The COVID-19 pandemic could materially adversely impact our business.

As  the  COVID-19  pandemic  continues  around  the  globe,  we  have  experienced  and  will  likely  continue  to  experience  disruptions  that  could
severely impact our business and clinical studies, which could include:

•

•

•

•

•

•

delays and/or difficulties in onboarding active patients and enrolling patients in our clinical studies;

delays and/or difficulties in clinical site initiation, including difficulties in recruiting clinical site investigators and clinical site staff;

declines in prescriptions written due to a perception that our Products are difficult to administer remotely or if patients are unwilling to
travel to treatment sites or receive in-home treatment assistance from us or other caregivers;

reductions in third-party reimbursements, which could materially affect our revenue, as most of our patients rely on third-party payers to
cover the cost of our Products and a material number of our patients could lose access to their private health insurance plan if they or
someone in their family lose their job;

diversion of healthcare resources away from conducting clinical studies, including the diversion of hospitals serving as our clinical study
sites and hospital staff supporting the conduct of our clinical studies;

interruption of key clinical study activities, such as clinical study site monitoring, due to limitations on travel imposed or recommended
by federal or state governments, employers and others;

32

•

•

•

•

•

•

•

•

•

•

•

•

•

staff disruptions and turnover internally and at treatment sites and third-party providers who provide support, either directly as a result of
illness or indirectly as a result of vaccine mandates and other changes in terms of employment;

delays in receiving approval from local regulatory authorities or IRBs to initiate our planned clinical studies;

delays in clinical sites receiving the supplies and materials needed to conduct our clinical studies;

interruption in global shipping that may affect the transport of active patient and clinical study materials;

changes  in  local  regulations  as  part  of  a  response  to  the  COVID-19  outbreak  that  may  require  us  to  change  the  ways  in  which  our
clinical studies are conducted, which may result in unexpected costs, or to discontinue the clinical studies altogether;

delays  in  necessary  interactions  with  local  regulators,  ethics  committees  and  other  important  agencies  and  contractors  due  to
limitations in employee resources or forced furlough of government employees;

disruption of our supply chain as our suppliers and common carriers are unable to meet our requirements to provide us the materials
we need for clinical study and active patient care needs;

indirect consequences of the COVID-19 pandemic on the global economy in general, such as an increase in bankruptcies of our key
suppliers, or the inability of our third-party payers to meet their obligations reimburse us in a timely fashion or at all;

postponements and cancellations of key conferences and meetings and travel restrictions could interfere with our ability to interact with
key thought leaders in the field, leading to a disruption in the rate of adoption of our technology;

access restrictions at offices, hospitals, and treatment centers, and stakeholder illness could interfere with the ability of our sales force
to engage in face-to-face visits with providers, leading to a disruption in the rate of adoption of our technology;

increases in expenditures for technology and other tools necessary to provide patient care in an environment where both patient and
care-giver travel is restricted and access to in-person interaction is limited;

refusal of the FDA to accept data from clinical studies in affected geographies outside the United States; and

patient delays in seeking or receiving treatment, either due to fear of infection or lack of access to treatment and study sites, leading to
fewer  diagnoses  of  the  indications  our  Products  are  approved  to  treat  or  more  advanced  procession  of  the  disease,  which  may
contraindicate the use of our Products or disqualify the patient from participating in a given study.

The  global  status  of  the  COVID-19  pandemic  continues  to  rapidly  evolve.  The  extent  to  which  the  pandemic  may  impact  our  business  and
clinical studies will depend on future developments, which are highly uncertain and cannot be predicted with confidence, such as the ultimate
geographic  spread  of  the  disease,  the  duration  of  the  pandemic,  travel  restrictions  and  social  distancing  guidelines,  business  closures  or
business  disruptions  and  the  effectiveness  of  actions  taken  to  contain  and  treat  the  disease.  The  response  to  the  pandemic  may  result  in
permanent changes to the environment in which we operate as described above in ways we are unable to predict. The COVID-19 pandemic
may also have the effect of heightening many of the other risks described herein.

We are increasingly dependent on information technology systems and subject to privacy and security laws. Our Products and our
systems and infrastructure face certain risks, including from cyber security breaches and data leakage.

We increasingly rely upon technology systems and infrastructure. Our technology systems, including our Products, are potentially vulnerable to
breakdown or other interruption by fire, power loss, system malfunction, unauthorized access and other events. Likewise, data privacy breaches
by employees and others with both permitted and unauthorized access to our Products and our systems may pose a risk that protected patient
information ("PI") may be exposed to unauthorized persons or to the public, or may be permanently lost. The increasing use and evolution of
technology,  including  cloud-based  computing,  creates  additional  opportunities  for  the  unintentional  dissemination  of  information,  intentional
destruction of confidential information stored in our systems or in non-encrypted portable media or storage devices. We could also experience a
business interruption, information theft of confidential information, or reputational damage from industrial espionage attacks, malware or other
cyber incidents, which may

33

compromise our system infrastructure or lead to data leakage, either internally or at our third-party service providers or other business partners.

The size and complexity of our computer systems, and scope of our geographic reach, make us potentially vulnerable to information technology
system  breakdowns,  internal  and  external  malicious  intrusion,  cyberattacks  and  computer  viruses.  Because  the  techniques  used  to  obtain
unauthorized access, or to sabotage systems, change frequently and generally are not recognized until launched against a target, we may be
unable  to  anticipate  these  techniques  or  to  implement  adequate  preventative  measures.  If  we  do  not  allocate  and  effectively  manage  the
resources  necessary  to  build  and  sustain  the  proper  technology  infrastructure  or  properly  manage  third-party  contractors  who  perform  data
management  services  on  our  behalf,  then  a  security  breach  could  subject  us  to,  among  other  things,  transaction  errors,  business  process
inefficiencies,  the  loss  of  customers,  damage  to  our  reputation,  business  disruptions  or  the  loss  of  or  damage  to  intellectual  property.  Such
security breaches could expose us to a risk of loss of information, litigation, penalties, remediation costs and potentially significant liability to
customers,  employees,  business  partners  and  regulatory  authorities,  including,  for  example,  under  the  Health  Insurance  Portability  and
Accountability  Act  of  1996  (“HIPAA”)  in  the  United  States  and  Regulation  2016/679  on  the  protection  of  natural  persons  with  regard  to  the
processing of personal data and on the free movement of such data under GDPR in the EU. If our data management systems (including third
party data management systems) do not effectively collect, secure, store, process and report relevant data for the operation of our business,
whether due to equipment malfunction or constraints, software deficiencies, or human error, our ability to effectively plan, forecast and execute
our business plan and comply with applicable laws and regulations will be impaired. Any such impairment could materially and adversely affect
our financial condition and results of operations.

While we have invested heavily in the protection of data and information technology and in related training, there can be no assurance that our
efforts will prevent significant breakdowns, breaches in our systems or other cyber incidents or ensure compliance with all applicable security
and  privacy  laws,  regulations  and  standards,  including  with  respect  to  third-party  service  providers  that  utilize  sensitive  personal  information,
including PI, on our behalf.

A security breach, whether of our Products, systems or third-party hosting services we utilize, could disrupt treatments being provided by our
Products, disrupt access to our customers’ stored information, such as patient treatment data and health information, and could lead to the loss
of, damage to or public disclosure of such data and information, including patient health information. Such an event could have serious negative
consequences,  including  possible  patient  injury,  regulatory  action,  fines,  penalties  and  damages,  reduced  demand  for  our  Products,  an
unwillingness of customers to use our Products, harm to our reputation and brand and time-consuming and expensive litigation, any of which
could have a material adverse effect on our financial results. We carry a limited amount of insurance for cybersecurity liability, and our insurance
coverage may be inadequate. In the future, our insurance coverage may be expensive or not be available on acceptable terms or in sufficient
amounts, if at all.

Risks relating to the regulation of our business

Our device candidates must undergo rigorous preclinical and clinical testing and we must obtain regulatory approvals, which could
be costly and time-consuming and subject us to unanticipated delays or prevent us from marketing any devices.

Our  research  and  development  activities,  as  well  as  the  manufacturing  and  marketing  of  our  Products,  are  subject  to  regulation,  including
regulation for safety, efficacy and quality, by the FDA in the U.S. In the EU member states where we market our Products and operate, we are
subject to, inter alia, the Medical Device Regulation ("MDR"), which applies directly in all EU member states. In Switzerland, our Products and
operations  are  subject  to,  inter  alia,  the  Medical  Devices  Ordinance,  which  implements  the  MDR  into  Swiss  law.  In  the  United  Kingdom,  our
Products and operation are subject to, inter alia, the Medical Devices Regulations 2002 and the Medical Devices (Amendment etc.) (EU Exit)
Regulations 2020 (the "UK Re, which implements the MDR and MDR like provisions into UK law. We are regulated by comparable authorities in
other countries. Regulations promulgated by the regulatory authorities in our applicable jurisdictions are wide-ranging and govern, among other
things:

•

•

•

•

the conduct of preclinical and clinical studies;

product design, development, manufacturing, testing, storage and shipping;

product labeling, advertising and promotion;

premarket clearance, approval and conformity assessment procedures, as well as for modifications introduced in marketed products;

34

•

•

•

•

post-market surveillance and monitoring;

reporting of adverse events or incidents and implementation of corrective actions, including product recalls;

interactions with healthcare professionals and patients; and

product sales and distribution.

We cannot be certain if or when the FDA, comparable regulatory agencies in other jurisdictions or our notified body might request additional or
modified studies on our Products, under what conditions such studies might be requested, or the required size or length of any such studies.
The  data  collected  from  our  clinical  studies  may  not  be  sufficient  to  support  regulatory  approval  in  the  U.S.,  Japan  and  other  countries  or  to
obtain a CE Certificate in the EU for our various future device candidates. Even if we believe the data collected from our clinical studies are
sufficient,  the  FDA  and  comparable  regulatory  bodies  in  other  jurisdictions  have  substantial  discretion  in  the  assessment  and  approval  or
conformity assessment processes and may disagree with our interpretation of the data. Our failure to adequately demonstrate the safety and
efficacy of any of our device candidates would delay or prevent regulatory approval in the U.S., Japan and other countries or delay or prevent a
CE Certificate in the EU (and therefore be unable to affix the CE mark) for our device candidates, which could prevent us from being sustainably
profitable. In addition, any change in the laws or regulations that govern the clearance and approval processes relating to our current and future
devices  could  make  it  more  difficult  and  costly  to  obtain  clearance  or  approval  for  new  devices,  or  to  produce,  market  and  distribute  our
Products. Significant delays in receiving clearance or approval, or the failure to receive clearance or approval for our new devices would have
an adverse effect on our ability to expand our business.

We intend to market our Products in a number of international markets in addition to our current markets. In order to market our Products in any
jurisdiction  and  for  other  indications  or  purposes,  we  may  be  required  to  obtain  separate  regulatory  approvals  or  CE  Certificates  for  our
Products, as applicable. The requirements governing the conduct of clinical studies and manufacturing and marketing of our device candidates
outside the U.S. vary widely from country to country. CE Certificates and regulatory approvals in other jurisdictions may take longer to obtain
than FDA approvals and can require, among other things, additional testing and different clinical study designs. CE Certification processes and
regulatory  approvals  in  other  jurisdictions  include  essentially  all  of  the  risks  associated  with  the  FDA  approval  processes.  Some  regulatory
agencies in other jurisdictions must also approve prices of our Products. Approval of a Product by the FDA does not guarantee approval of the
same  product  by  the  health  authorities  of  other  countries  or  CE  marking  of  our  Products  in  the  EU  and  vice  versa.  In  addition,  changes  in
regulatory policy in the U.S. or in other countries for the approval or CE marking of a medical device during the period of product development
and regulatory agency review or notified body review of each submitted new application may cause delays or rejections.

In the European Economic Area (“EEA”), we are required to obtain a CE Certificate and to affix a CE mark to our Products. In the EEA, our
devices  must  be  subject  to  conformity  assessment  procedure  involving  an  EEA  notified  body,  a  private  organization  accredited  by  an  EEA
member  state  to  conduct  conformity  assessment  procedures  under  the  MDR.  The  notified  body  typically  audits  and  examines  the  device’s
technical documentation, including the clinical evaluation, and the quality system for the manufacture, design and final inspection of our devices
before issuing a CE Certificate demonstrating compliance with the relevant requirements or the quality system requirements laid down in the
relevant  Annexes  to  the  MDR.  The  MDR  became  active  on  May  26,  2021  and  replaced  Council  Directive  93/42/EEC  concerning  medical
devices  (“MDD”)  with  transitional  provisions  for  "legacy"  devices  under  the  MDD.  The  MDR  introduced  significant  changes  to  the  regulatory
framework for medical devices in the EU. including new, stricter requirements that we must comply with in order to obtain CE Certificates for
new product candidates, and to renew the CE Certificates for our "legacy" MDD-Products when they expire or by December 31, 2027 or 2028,
depending on device class, whichever occurs first. These changes may prevent or delay the CE Certification of our device candidates or impact
our ability to modify our Products on a timely basis. In particular, the delay in the publication of key MDR guidance documents at EU level and
the  limited  availability  of  qualified  notified  bodies  might  affect  our  ability  to  timely  comply  and  demonstrate  such  compliance  with  the  new
requirements or delay the MDR CE Certification of our device candidates. Further, as a result of the implementation of the MDR, our notified
body (as well as many other notified bodies throughout the EEA) has suffered a significant backlog in issuing CE Certificate renewals. In the
UK, we may continue to market and sell our Products under the CE mark until June 2023. Thereafter, our Products will be regulated under the
UK Regulations. There can be no assurance that the UK Regulations will be interpreted by UK regulators in the same manner as the MDR in
the future, which may prevent or delay the UK CE certification of our device candidates or impact our ability to modify our Products on a timely
basis

35

We may choose to, or may be required to, suspend, repeat or terminate our clinical studies if they are not conducted in accordance
with regulatory requirements, the results are negative or inconclusive or the studies are not well designed.

Clinical  studies  must  be  conducted  in  accordance  with  the  FDA’s  cGCPs  and  the  equivalent  laws  and  regulations  applicable  in  other
jurisdictions in which the clinical studies are conducted. The clinical studies are subject to oversight by the FDA, regulatory agencies in other
jurisdictions, ethics committees and institutional review boards at the medical institutions where the clinical studies are conducted. In addition,
clinical  studies  must  be  conducted  with  device  candidates  produced  under  the  FDA’s  QSR  and  in  accordance  with  the  applicable  regulatory
requirements in the other jurisdictions in which the clinical studies are conducted. The conduct of clinical studies may require large numbers of
test patients.

The FDA or regulatory agencies in other jurisdictions might delay or terminate our clinical studies of a device candidate for various reasons,
including:

•

the device candidate may have unforeseen adverse side effects or may not appear to be more effective than current therapies;

• we  may  not  agree  with  the  FDA,  a  regulatory  authority  in  another  jurisdiction  or  an  ethics  committee  regarding  the  protocol  for  the

conduct of a clinical study;

•

•

new therapies may become the standard of care while we are conducting our clinical studies, which may require us to revise or amend
our clinical study protocols or terminate a clinical study; or

fatalities may occur during a clinical study due to medical problems that may or may not be related to clinical study treatments.

Furthermore, the process of obtaining and maintaining regulatory approvals in the U.S. and other jurisdictions and CE Certification in the EU for
new therapeutic products is lengthy, expensive and uncertain. It can vary substantially, based on the type, complexity and novelty of the product
involved.  Accordingly,  any  of  our  device  candidates  could  take  a  significantly  longer  time  than  we  expect  to,  or  may  never,  gain  regulatory
approval or obtain CE Certification in the EU, which could have a material adverse effect on our business, prospects, financial condition and
results of operations and cause our stock price to decline.

The process of obtaining and maintaining regulatory approvals may be further complicated when we seek approval for indications involving the
use  of  our  products  together  with  pharmacological/immunological  therapies  and  therapy  candidates.  If  our  regulators  determine  that  the
predominant questions stem from the pharmacological/immunological therapy in the study, they may require us and our partners to conduct the
study under trial rules and regulations governing pharmacological/immunological therapies, which may differ significantly from medical device
requirements. Adhering to pharmacological/immunological regulations and requirements governing clinical trials could make it more difficult to
enroll study sites and patients, increase compliance costs and lengthen the time it takes to complete the study.

Legislative  and  regulatory  changes  in  the  U.S.  and  in  other  countries  regarding  healthcare  insurance  and  government-sponsored
reimbursement programs (such as Medicare in the United States) may adversely affect our business and financial results.

We  rely  to  a  material  degree  on  highly  regulated  private  and  government-run  health  insurance  programs  for  our  revenue  in  most  of  the
countries in which we operate. The laws and regulations regarding health care programs, both public and private, are driven by public policy
considerations that may be unrelated to the direct provision of patient care, such as lowering costs or requiring or limiting access to healthcare
options.  These  laws  and  regulations  are  very  complicated  and  there  are  many  requirements  we  must  satisfy  in  order  for  our  Products  to
become and remain eligible for reimbursement under these programs. In many cases we may have limited negotiating power when negotiating
reimbursement rates for our Products.

In the future, lawmakers and regulators could also pass additional healthcare laws and implement other regulatory changes at both the national
and local levels. These laws and regulations could potentially affect coverage and reimbursement for our Products. However, we cannot predict
the ultimate content, timing or effect of any future healthcare initiatives or the impact any future legislation or regulation will have on us.

With respect to countries outside the U.S., the national competent authorities in the EU member states, the UK, Switzerland, Israel, Japan, and
other jurisdictions are also increasingly active in their goal of reducing public spending on healthcare. We cannot, therefore, guarantee that the
treatment of patients with our Products would be

36

reimbursed in any particular country or, if successfully included on reimbursement lists, whether we will remain on such lists.

We  are  subject  to  extensive  post-marketing  regulation  by  the  FDA  and  comparable  authorities  in  other  jurisdictions,  which  could
impact the sales and marketing of our Products and could cause us to incur significant costs to maintain compliance. In addition, we
may become subject to additional regulation in other jurisdictions as we increase our efforts to market and sell Optune or Optune Lua
and future Products outside of the U.S.

We  market  and  sell  our  Products,  and  expect  to  market  and  sell  future  Products,  subject  to  extensive  regulation  by  the  FDA  and  numerous
other  federal,  state  and  governmental  authorities  in  other  jurisdictions.  These  regulations  are  broad  and  relate  to,  among  other  things,  the
conduct  of  preclinical  and  clinical  studies,  product  design,  development,  manufacturing,  labeling,  testing,  product  storage  and  shipping,
premarket  clearance  and  approval,  conformity  assessment  procedures,  premarket  clearance  and  approval  of  modifications  introduced  in
marketed products, post-market surveillance and monitoring, reporting of adverse events and incidents, pricing and reimbursement, interactions
with  healthcare  professionals,  interactions  with  patients,  information  security,  advertising  and  promotion  and  product  sales  and  distribution.
Although we have received FDA approval to market Optune in the U.S. for the treatment of adult patients with newly diagnosed GBM (together
with  temozolomide)  and  recurrent  GBM  and  approval  to  market  Optune  Lua  for  adults  patients  with  MPM,  we  will  require  additional  FDA
approval to market our Products for other indications. We may be required to obtain approval of a new PMA, HDE or PMA/HDE supplement
application for modifications made to our Products. This approval process is costly and uncertain, and it could take one to three years, or longer,
from the time the application is filed with the FDA. We may make modifications in the future that we believe do not or will not require additional
approvals. If the FDA disagrees, and requires new PMAs, HDEs, or PMA/HDE supplements for the modifications, we may be required to recall
and to stop marketing the modified versions of our Products.

In addition, before our Products can be marketed in the EU, our Products must obtain a CE Certificate from a notified body. New intended uses
of CE marked medical devices falling outside the scope of the current CE Certificate require a completely new conformity assessment before
the device can be CE marked and marketed in the EU for the new intended use. The process required to gather necessary information and
draw up documentation in order to obtain CE Certification of a medical device in the EU can be expensive and lengthy and its outcome can be
uncertain. We may make modifications to our Products in the future that we believe do not or will not require notifications to our notified body or
new conformity assessments to permit the maintenance of our current CE Certificate. If the competent authorities of the EU member states or
our  notified  body  disagree  and  require  the  conduct  of  a  new  conformity  assessment,  the  modification  of  the  existing  CE  Certificate  or  the
issuance of a new CE Certificate, we may be required to recall or suspend the marketing of the modified versions of our Products.

In  Japan,  new  medical  devices  or  new  therapeutic  uses  of  medical  devices  falling  outside  the  scope  of  the  existing  approval  by  the  MHLW
require  a  new  assessment  and  approval  for  each  such  new  device  or  use.  Accordingly,  we  may  be  required  to  obtain  a  new  approval  from
MHLW before we launch a modified version of our Products or the use of our Products for additional indications. Approval time frames from the
MHLW  vary  from  simple  notifications  to  review  periods  of  one  or  more  years,  depending  on  the  complexity  and  risk  level  of  the  device.  In
addition, importation into Japan of medical devices is subject to "Quality Management System (QMS) Ordinance," which includes the equivalent
of "Good Import" regulations in the U.S. As with any highly regulated market, significant changes in the regulatory environment could adversely
affect our ability to commercialize Optune in Japan.

In the U.S. and other jurisdictions, we also are subject to numerous post-marketing regulatory requirements, which include regulations under
the QSR related to the manufacturing of our Products, labeling regulations and medical device reporting regulations, which require us to report
to the FDA or comparable regulatory authorities in other jurisdictions and our notified body if our Products cause or contributes to a death or
serious  injury,  or  malfunction  in  a  way  that  would  likely  cause  or  contribute  to  a  death  or  serious  injury.  In  addition,  these  regulatory
requirements may in the future change in a way that adversely affects us. If we fail to comply with present or future regulatory requirements that
are applicable to us, we may be subject to enforcement action by the FDA or comparable regulatory authorities in other jurisdictions and notified
bodies, which may include any of the following sanctions:

•

•

•

•

untitled letters, warning letters, fines, injunctions, consent decrees and civil penalties;

unanticipated expenditures to address or defend such actions;

patient notification, or orders for repair, replacement or refunds;

voluntary or mandatory recall, withdrawal or seizure of our current or future devices;

37

•

•

•

•

•

•

•

•

•

•

administrative detention by the FDA or other regulatory authority in another jurisdiction of medical devices believed to be adulterated or
misbranded;

operating restrictions, suspension or shutdown of production;

refusal  or  delay  of  our  requests  for  PMA  or  analogous  approval  for  new  intended  uses  for  or  modifications  to  our  Products  or  for
approval of new devices;

refusal or delay in obtaining CE Certificates for new intended uses for or modifications to our Products;

suspension, variation or withdrawal of the CE Certificates granted by our notified body in the EU;

prohibition or restriction of Products being placed on the market;

operating restrictions;

suspension or withdrawal of PMA or analogous approvals that have already been granted;

refusal to grant export approval for our Products or any device candidates; or

criminal prosecution.

The  occurrence  of  any  of  these  events  could  have  a  material  adverse  effect  on  our  business,  prospects,  financial  condition  and  results  of
operations and cause our stock price to decline.

Over time, we expect to make modifications to our Products that are designed to improve efficacy, reduce side effects, enhance the
user  experience  and  other  purposes.  Modifications  to  our  Products  may  require  approvals  of  new  PMAs,  HDEs,  or  PMA/HDE
supplement applications, modified or new CE Certificates and analogous regulatory approvals in other jurisdictions or even require
us  to  cease  promoting  or  to  recall  the  modified  versions  of  our  Products  until  such  clearances,  approvals  or  modified  or  new  CE
Certificates are obtained, and the FDA, comparable regulatory authorities in other jurisdictions or our notified body may not agree
with our conclusions regarding whether new approvals are required.

Any  modification  to  a  device  approved  through  the  PMA  or  HDE  pathway  that  impacts  the  safety  or  effectiveness  of  the  device  requires
submission to the FDA and FDA approval of a PMA supplement application or even a new PMA or HDE application, as the case may be. The
FDA requires a company to make the determination as to whether a new PMA, HDE or PMA/HDE supplement application is to be filed, but the
FDA  may  review  the  company’s  decision.  For  example,  in  the  past,  we  have  made  initial  determinations  that  certain  modifications  did  not
require the filing of a new PMA or PMA/HDE supplement application and have notified the FDA of these changes in our PMA Annual Report,
but  after  its  review  of  our  PMA  Annual  Report,  the  FDA  requested  that  we  submit  these  modifications  to  the  FDA  as  a  PMA  supplement
application.  From  time  to  time,  we  may  make  other  changes  to  the  devices,  software,  packaging,  manufacturing  facilities  and  manufacturing
processes and may submit additional PMA/HDE supplement applications for these changes. FDA may conduct a facility inspection as part of its
review and approval process. In addition, it is possible that the FDA will require a human factors (user interface) study. It is also possible that
the FDA may require additional clinical data. We can provide no assurance that we will receive FDA approval for these changes on a timely
basis,  or  at  all.  We  also  may  make  additional  changes  in  the  future  that  we  may  determine  do  not  require  the  filing  of  a  new  PMA,  HDE  or
PMA/HDE supplement application. The FDA may not agree with our decisions regarding whether the filing of new PMAs, HDEs or PMA/HDE
supplement applications are required.

In  addition,  any  substantial  change  introduced  to  a  medical  device  or  to  the  quality  system  certified  by  our  notified  body  requires  a  new
conformity assessment of the device and can lead to changes to the CE Certificates or the preparation of a new CE Certificate of Conformity.
Substantial changes may include, among others, the introduction of a new intended use of the device, a change in its design or a change in the
company’s  suppliers.  Responsibility  for  determination  that  a  modification  constitutes  a  substantial  change  lies  with  the  manufacturer  of  the
medical device. We must inform the notified body that conducted the conformity assessment of the Products we market or sell in the EU of any
planned substantial changes to our quality system or changes to our Products that could, among other things, affect compliance with the MDR
or the devices’ intended use. The notified body will then assess the changes and verify whether they affect the Product’s conformity with the
Essential Requirements laid down in Annex I to the MDR or the conditions for the use of the device. If the assessment is favorable, the notified
body will issue a new CE Certificate or an addendum to the existing CE Certificate attesting compliance with the Essential Requirements laid
down in Annex I to the MDR. There is a risk that the competent authorities of the EU member states or our notified body may disagree with our
assessment of the changes introduced to our Products. The competent authorities of the EU member states or our notified body also may come
to a different conclusion than the FDA on any given product modification.

38

In addition, "legacy" medical devices that have obtained a CE Certification under the MDD may in principle continue to be marketed under such
CE Certificate until the CE Certificate expires but at the latest by December 31, 2027 or 2028, depending on device class, under transitional
provisions  as  amended  in  February  2023,  provided  that  the  manufacturer  complies  with  the  MDR’s  additional  requirements  related  to  post-
marketing surveillance, market surveillance, vigilance, and registration of economic operators and of devices. However, if such medical devices
undergo a significant change in their design or intended use, we would need to obtain a new CE Certificate under the MDR for these devices.

If the FDA disagrees with us and requires us to submit a new PMA, HDE, or PMA/HDE supplement application for then-existing modifications
and/or  the  competent  authorities  of  the  EU  member  states  or  our  notified  body  disagree  with  our  assessment  of  the  change  introduced  in  a
product, its design or its intended use, we may be required to cease promoting or to recall the modified product until we obtain approval and/or
until a new conformity assessment has been conducted in relation to the product, as applicable. In addition, we could be subject to significant
regulatory fines or other penalties. Furthermore, our Products could be subject to recall if the FDA, comparable regulatory authorities in other
jurisdictions,  or  our  notified  body  determine,  for  any  reason,  that  our  Products  are  not  safe  or  effective  or  that  appropriate  regulatory
submissions were not made. Any recall or requirement that we seek additional approvals or clearances could result in significant delays, fines,
increased  costs  associated  with  modification  of  a  product,  loss  of  revenues  and  potential  operating  restrictions  imposed  by  the  FDA,
comparable foreign regulatory authorities in other jurisdictions, or our notified body. Delays in receipt or failure to receive approvals/certification,
or  the  failure  to  comply  with  any  other  existing  or  future  regulatory  requirements,  could  reduce  our  sales,  profitability  and  future  growth
prospects.

In addition to FDA requirements, we will spend considerable time and money complying with other federal, state, local and foreign
rules,  regulations  and  guidance  and,  if  we  are  unable  to  fully  comply  with  such  rules,  regulations  and  guidance,  we  could  face
substantial penalties.

We are subject to extensive regulation by the U.S. federal government and the states and other countries in which we conduct our business.
U.S. federal government healthcare laws apply when we submit a claim on behalf of a U.S. federal healthcare program beneficiary, or when a
customer  submits  a  claim  for  an  item  or  service  that  is  reimbursed  under  a  U.S.  federal  government-funded  healthcare  program,  such  as
Medicare or Medicaid. The laws that affect our ability to operate our business in addition to the Federal Food, Drug, and Cosmetic Act and FDA
regulations include, but are not limited to, the following:

•

•

•

the  Federal  Anti-Kickback  Statute,  an  intent-based  federal  criminal  statute  which  prohibits  knowingly  and  willfully  offering,  providing,
soliciting  or  receiving  remuneration  of  any  kind  to  induce  or  reward,  or  in  return  for,  referrals  or  the  purchase,  lease,  order  or
recommendation or arranging of any items or services reimbursable by a federal healthcare program;

the Federal Civil False Claims Act, which imposes civil penalties, including through civil whistleblower or "qui tam" actions, for knowingly
submitting or causing the submission of false or fraudulent claims of payment to the federal government, knowingly making, using or
causing to be made or used a false statement or record material to payment of a false claim or avoiding, decreasing or concealing an
obligation to pay money to the federal government;

the Federal Criminal False Claims Act, which is similar to the Federal Civil False Claims Act and imposes criminal liability on those that
make or present a false, fictitious or fraudulent claim to the federal government;

• Medicare laws and regulations that prescribe requirements for coverage and reimbursement, including the conditions of participation for
DME  suppliers,  and  laws  prohibiting  false  claims  or  unduly  influencing  selection  of  products  for  reimbursement  under  Medicare  and
Medicaid;

•

•

•

healthcare fraud statutes that prohibit false statements and improper claims to any third-party payer;

the Federal Physician Self-Referral Law, commonly known as the Stark law, which, absent an applicable exception, prohibits physicians
from  referring  Medicare  and  Medicaid  patients  to  an  entity  for  the  provision  of  certain  designated  health  services  (“DHS”),  including
DME, if the physician (or a member of the physician’s immediate family) has an impermissible financial relationship with that entity and
prohibits the DHS entity from billing for such improperly referred services;

the  Federal  Beneficiary  Anti-Inducement  Statute,  which  prohibits  the  offering  of  any  remuneration  to  a  beneficiary  of  Medicare  or
Medicaid that is likely to influence that beneficiary’s choice of provider or supplier. This can include, but is not limited to, inappropriate
provision of patient services including financial

39

assistance.  Recent  government  investigations  have  focused  on  this  particular  prohibition.  There  are  established  exceptions  from
liability, but we cannot guarantee that all of our practices will fall squarely within those exceptions;

•

•

•

•

•

similar  state  anti-kickback,  false  claims,  insurance  fraud  and  self-referral  laws,  which  may  not  be  limited  to  government-reimbursed
items, as well as state laws that require us to maintain permits or licenses to distribute DME;

federal  and  state  accreditation  and  licensing  requirements  applicable  to  DME  providers  and  equivalent  requirements  in  other
jurisdictions;

the  U.S.  Foreign  Corrupt  Practices  Act,  which  can  be  used  to  prosecute  companies  in  the  U.S.  for  arrangements  with  physicians  or
other parties outside the U.S. if the physician or party is a government official of another country and the arrangement violates the law
of that country;

the  Federal  Trade  Commission  Act,  the  Lanham  Act  and  similar  federal  and  state  laws  regulating  truthfulness  in  advertising  and
consumer protection; and

the  Federal  Physician  Payments  Sunshine  Act,  the  French  Sunshine  Act  and  similar  state  and  foreign  laws,  which  require  periodic
reporting of payments and other transfers of value made to U.S. and French-licensed physicians, teaching hospitals, and in the U.S.,
physician assistants, nurse practitioners, clinical nurse specialists, certified nurse anesthetists, and certified nurse-midwives.

Similar laws exist in the EU, individual EU member states and other countries. These laws are complemented by EU or national professional
codes of practices.

HIPAA  provides  data  privacy  and  security  provisions  for  safeguarding  medical  information.  Additionally,  states  in  the  U.S.  are  enacting  local
privacy  laws  (e.g.,  California).  In  the  EU,  the  GDPR  harmonizes  data  privacy  laws  and  rules  on  the  processing  of  personal  data,  including
patient  and  employee  data,  across  the  EU.  The  GDPR  has  a  number  of  strict  data  protection  and  security  requirements  for  companies
processing data of EU residents, including when such data is transferred outside of the EU. Additionally, we need to comply with analogous
privacy  laws  in  other  jurisdictions  in  which  we  operate,  such  as  the  Israeli  Privacy  Protection  Law,  the  Asia  Pacific  Economic  Cooperation
Privacy Framework, and Japan’s Act on the Protection of Personal Information.

The laws and codes of practices applicable to us are subject to evolving interpretations. Moreover, certain U.S. federal and state laws regarding
healthcare fraud and abuse and certain laws in other jurisdictions regarding interactions with healthcare professionals and patients are broad
and  we  may  be  required  to  restrict  certain  of  our  practices  to  be  in  compliance  with  these  laws.  Healthcare  fraud  and  abuse  laws  also  are
complex and even minor, inadvertent irregularities, or even the perception of impropriety, can potentially give rise to claims that a statute has
been violated.

Any violation of these laws could have a material adverse effect on our business, prospects, financial condition and results of operations and
cause  our  stock  price  to  decline.  Similarly,  if  there  is  a  change  in  law,  regulation  or  administrative  or  judicial  interpretations,  we  may  have  to
change our business practices or our existing business practices could be challenged as unlawful, which likewise could have a material adverse
effect  on  our  business,  prospects,  financial  condition  and  results  of  operations  and  cause  our  stock  price  to  decline.  Fines  and  penalties  for
violations of these laws and regulations could include severe criminal and civil penalties, including, for example, significant monetary damages,
exclusion from participation in the federal healthcare programs and permanent disbarment of key employees. Any penalties, damages, fines,
curtailment or restructuring of our operations would adversely affect our ability to operate our business, our prospects and our financial results.
In addition, any action against us for violation of these laws, even if we successfully defend against it, could cause us to incur significant legal
expenses, divert our management’s attention from the operation of our business and damage our reputation.

In addition, although we believe that we have the required licenses, permits and accreditation to dispense our Products in the future, a regulator
could find that we need to obtain additional licenses or permits. We also may be subject to mandatory reaccreditation and other requirements in
order  to  maintain  our  billing  privileges.  Failure  to  satisfy  those  requirements  could  cause  us  to  lose  our  privileges  to  bill  governmental  and
private  payers.  If  we  are  required  to  obtain  permits  or  licenses  that  we  do  not  already  possess,  we  also  may  become  subject  to  substantial
additional regulation or incur significant expense.

To ensure compliance with Medicare, Medicaid and other regulations, federal and state governmental agencies and their agents, including DME
MACs, may conduct audits of our operations to support our claims submitted for reimbursement of items furnished to beneficiaries and health
care providers. Depending on the nature of the conduct found in such audits and whether the underlying conduct could be considered systemic,
the resolution of these audits could adversely impact our revenue, financial condition and results of operations.

40

If  we,  our  collaborative  partners,  our  contract  manufacturers  or  our  component  suppliers  fail  to  comply  with  the  FDA’s  QSR  or
equivalent regulations established in other countries, the manufacturing and distribution of our Products could be interrupted, and
our Product sales and results of operations could suffer.

We, our collaborative partners, our contract manufacturers and our component suppliers are required to comply with the FDA’s QSR and the
equivalent quality system requirements imposed by the laws and regulations in other jurisdictions, which are a complex regulatory framework
that covers the procedures and documentation of the design, testing, production, control, quality assurance, labeling, packaging, sterilization,
storage and shipping of our Products. We cannot assure you that our facilities or our contract manufacturers’ or component suppliers’ facilities
would  pass  any  future  quality  system  inspection.  If  our  or  any  of  our  contract  manufacturers’  or  component  suppliers’  facilities  fails  a  quality
system inspection, the manufacturing or distribution of our Products could be interrupted and our operations disrupted. Failure to take adequate
and timely corrective action in response to an adverse quality system inspection could force a suspension or shutdown of our packaging and
labeling  operations  or  the  manufacturing  operations  of  our  contract  manufacturers,  and  lead  to  suspension,  variation  or  withdrawal  of  our
regulatory approvals or a recall of our Products. If any of these events occurs, we may not be able to provide our customers with our Products
on a timely basis, our reputation could be harmed and we could lose customers, any or all of which could have a material adverse effect on our
business, prospects, financial condition and results of operations and cause our stock price to decline.

Our Products may in the future be subject to recalls that could harm our reputation, business and financial results.

The FDA and similar governmental authorities in other jurisdictions have the authority to require the recall of commercialized products in the
event of material deficiencies or defects in design or manufacture. In the case of the FDA, the authority to require a recall must be based on an
FDA finding that there is a reasonable probability that the device would cause serious injury or death. In addition, governmental bodies in other
jurisdictions have the authority to require the recall of our Products in the event of material deficiencies or defects in design or manufacture.
Distributors and manufacturers may, under their own initiative, recall a product if any material deficiency in a device is found. A government-
mandated or voluntary recall by us or one of our manufacturers could occur as a result of component failures, manufacturing errors, design or
labeling  defects  or  other  deficiencies  and  issues.  The  FDA  requires  that  certain  classifications  of  recalls  be  reported  to  the  FDA  within  ten
working  days  after  the  recall  is  initiated.  Requirements  for  the  reporting  of  product  recalls  to  the  competent  authorities  are  imposed  in  other
jurisdictions in which our Products are or would be marketed in the future. Companies are required to maintain certain records of recalls, even if
they are not reportable to the FDA or to the competent authorities of other countries. In the future, we may initiate voluntary recalls involving our
Products that we determine do not require notification of the FDA or to other equivalent non-U.S. authorities. If the FDA or the equivalent non-
U.S. authorities disagree 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  sales.  In  addition,  the  FDA  and  the  equivalent  non-U.S.  authorities  could  take
enforcement  action  if  we  fail  to  report  the  recalls  when  they  were  conducted.  Recalls  of  our  Products  would  divert  managerial  and  financial
resources  and  could  have  a  material  adverse  effect  on  our  business,  prospects,  financial  condition  and  results  of  operations  and  cause  our
stock price to decline.

If our 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 and the equivalent regulations applicable in other jurisdictions in which our Products are
or may be marketed in the future, medical device manufacturers are required to report to the FDA and to the equivalent non-U.S. authorities
information that a device has or may have caused or contributed to a death or serious injury or has malfunctioned in a way that would likely
cause or contribute to death or serious injury if the malfunction of the device or one of our similar devices were to recur. If we fail to report these
events  to  the  FDA  or  to  the  equivalent  authorities  in  other  jurisdictions  within  the  required  time  frames,  or  at  all,  the  FDA  or  the  equivalent
authorities in other jurisdictions could take enforcement action against us. Any such adverse event involving our Products also could result in
future voluntary corrective actions, such as recalls or customer notifications, or agency action, such as inspection or 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.

41

We may be subject to fines, penalties or injunctions if we are determined to be promoting the use of our Products for unapproved or
off-label uses.

Medical devices may be marketed only for the indications for which they are approved. Our promotional materials and training materials must
comply  with  FDA  regulations  and  other  applicable  laws  and  regulations  governing  the  promotion  of  our  Products  in  the  U.S.  and  other
jurisdictions.  Currently,  Optune  is  approved  for  treatment  of  adult  patients  with  newly  diagnosed  GBM  (together  with  temozolomide)  and
recurrent GBM in the U.S. and is approved for treatment of adult patients with GBM in Japan. In the EU and Switzerland, we have CE marked
the  Optune  for  the  treatment  of  newly  diagnosed  GBM  (together  with  temozolomide),  recurrent  GBM,  and  advanced  NSCLC  (together  with
standard-of-care chemotherapy). Optune is also approved in Israel and in Australia for the treatment of recurrent GBM and newly diagnosed
GBM  (together  with  temozolomide).  The  Optune  Lua  System  is  only  approved  in  the  U.S.,  the  EU  and  Switzerland  for  the  treatment  of
unresectable, locally advanced or metastatic MPM.

If  the  FDA  or  the  competent  authorities  in  other  jurisdictions,  including  the  EU  member  states,  determine  that  our  promotional  materials  or
training constitutes promotion of an unapproved use, they could request that we modify our training or promotional materials or subject us to
regulatory or enforcement actions, including the issuance of an untitled or warning letter, an injunction, seizure, civil fines and criminal penalties.
It  is  also  possible  that  authorities  in  other  federal,  state  or  national  enforcement  in  other  jurisdictions  might  take  action  if  they  consider  our
promotional or training materials to constitute promotion of an unapproved use, which could result in significant fines or penalties under other
statutory  authorities,  such  as  laws  prohibiting  false  claims  for  reimbursement.  In  that  event,  our  reputation  could  be  damaged  and  the
commercialization of our Products could be impaired.

We pay taxes in multiple jurisdictions and adverse determinations by taxing or other governmental authorities or changes in tax laws,
rates or our status under which tax jurisdictions apply to us could increase our tax burden or otherwise affect our financial condition
or results of operations, as well as subject our shareholders to additional taxes.

The amount of taxes we pay is subject to a variety of tax laws in the various jurisdictions in which we and our subsidiaries are organized and
operate.  Our  domestic  and  international  tax  liabilities  are  dependent  on  the  location  of  earnings  among  these  various  jurisdictions.  Such  tax
liabilities could be affected by changes in tax or other laws, treaties, and regulations, as well as the interpretation or enforcement thereof by tax
or other governmental entities in any relevant jurisdiction. The amount we pay in tax to any particular jurisdiction depends, in part, on the correct
interpretation  of  the  tax  laws  in  such  jurisdiction,  and  we  have  made  a  number  of  determinations  as  to  the  effect  of  such  tax  laws  in  our
particular circumstances. In some cases, the determinations we have made as to the effect of the tax laws in a particular jurisdiction depend on
the  continuing  effectiveness  of  administrative  rulings  we  have  received  from  the  tax  authorities  in  that  jurisdiction,  while  in  other  cases,  our
determinations are based on the reasoned judgment of our tax advisors. Although we believe that we are in compliance with the administrative
rulings we have received, that the assumptions made by our tax advisors in rendering their advice remain correct, and that as a result we are in
compliance with applicable tax laws in the jurisdictions where we and our subsidiaries are organized and operate, a taxing authority in any such
jurisdiction may challenge our interpretation of those laws and assess us or any of our subsidiaries with additional taxes, penalties, fees and
interest.

Additionally, from time to time, proposals can be made and legislation can be introduced to change the tax laws, regulations or interpretations
thereof  (possibly  with  retroactive  effect)  of  various  jurisdictions  or  limit  tax  treaty  benefits  that,  if  enacted,  could  materially  increase  our  tax
burden,  increase  our  effective  tax  rate  or  otherwise  have  a  material  adverse  impact  on  our  financial  condition  and  results  of  operations.  It  is
possible  that  these  changes  could  adversely  affect  our  business.  While  we  monitor  proposals  and  other  developments  that  would  materially
impact our tax burden and effective tax rate and investigate our options accordingly, we could still be subject to increased taxation on a going
forward and retroactive basis no matter what action we undertake if certain legislative proposals or regulatory changes are enacted, certain tax
treaties  are  amended  and/or  our  interpretation  of  applicable  tax  or  other  laws  is  challenged  and  determined  to  be  incorrect.  Any  alternative
interpretations of applicable tax laws asserted by a tax authority or changes in tax laws, regulations or accounting principles that limit our ability
to take advantage of tax treaties between jurisdictions, modify or eliminate the deductibility of various currently deductible payments, increase
the tax burden of operating or being resident in a particular country, result in transfer pricing adjustments or otherwise require the payment of
additional taxes, may have a material adverse effect on our cash flows, financial condition and results of operations. The termination or revision
of any of our tax rulings or indirect tax exemptions that we have or may have in the future may have a material adverse effect on our cash flows,
financial condition and results of operations.

42

We are affected by and subject to environmental laws and regulations that could be costly to comply with or that may result in costly
liabilities.

We  are  subject  to  environmental  laws  and  regulations,  including  those  that  impose  various  environmental  controls  on  the  manufacturing,
transportation, storage, use and disposal of batteries and hazardous chemicals and other materials used in, and hazardous waste produced by,
the manufacturing of our Products. We incur and expect to continue to incur costs to comply with these environmental laws and regulations.
Additional or modified environmental laws and regulations, including those relating to the manufacture, transportation, storage, use and disposal
of materials used to manufacture our Products or restricting disposal or transportation of batteries, may be imposed that may result in higher
costs.

In addition, we cannot predict the effect that additional or modified environmental laws and regulations may have on us, our third-party suppliers
of  equipment,  batteries  and  our  Products  or  our  customers.  For  example,  we  and  our  suppliers  rely  on  the  exemption  in  European  Directive
2011/65/EU  relating  to  the  restriction  of  the  use  of  certain  hazardous  substances  in  electrical  and  electronic  equipment,  set  out  in  Annex  IV,
relating to lead content in our arrays. To the extent this exemption is revoked or amended, it may have a material impact on our business and
results of operations.

Safety issues concerning lithium-ion batteries could have a material adverse impact on our business.

Our Products use lithium-ion batteries. On rare occasions, lithium-ion cells can rapidly release the energy they contain by venting smoke, heat,
and  flames  in  a  manner  that  can  ignite  nearby  materials  as  well  as  other  lithium-ion  cells.  A  failure  in  the  lithium-ion  battery  contained  in  a
Product could occur, which could result in accidents, casualty or damages, and subject us to lawsuits, product recalls, or redesign efforts. In
addition, we store a significant number of lithium-ion cells at our facilities. Any failure of battery cells or a safety issue or fire related to the cells
could disrupt our operations. Such damage or injury could lead to adverse publicity and potentially a safety recall. The transportation of lithium
and lithium-ion batteries is regulated worldwide.

Laws regulating the transportation of batteries have been and may be enacted which could impose additional costs that could harm our ability to
be  profitable.  If  additional  restrictions  are  put  in  place  that  limit  our  ability  to  ship  our  Products  by  air  freight  or  on  water  borne  cargo,  such
restrictions  could  have  an  adverse  effect  on  our  supply  chain,  our  inventory  management  procedures  and  processes  and  our  ability  to  fill
prescriptions and service patients in a timely manner, which could have a material adverse effect on our business, prospects, financial condition
and  results  of  operations.  In  addition,  compliance  with  future  worldwide  or  International  Air  Transport  Association  approval  process  and
regulations could require significant time and resources from our technical staff and, if redesign were necessary, could delay the introduction of
new Products.

Risks relating to intellectual property

If we fail to protect, sustain, further build and enforce our intellectual property rights, including to our proprietary technology, trade
secrets or know how, competitors may be able to develop competing therapies.

Our success depends, in part, on our ability to obtain and maintain protection for our Products and technologies under the patent laws or other
intellectual  property  laws  of  the  U.S.  and  other  countries.  The  standards  that  the  U.S.  Patent  and  Trademark  Office  ("USPTO")  and  its
counterparts  in  other  jurisdictions  use  to  grant  patents  are  not  always  applied  predictably  or  uniformly  and  can  change.  Consequently,  we
cannot be certain as to whether pending patent applications will result in issued patents, and we cannot be certain as to the type and extent of
patent  claims  that  may  be  issued  to  us  in  the  future.  Any  issued  patents  may  not  contain  claims  that  will  permit  us  to  stop  competitors  from
using similar technology.

Our current intellectual property portfolio consists of hundreds of issued patents in multiple jurisdictions covering various aspects of our devices
and related technology. The legal scope of our patents vary, with some having broad coverage and others having narrow coverage, for example
being limited to certain intensities and frequencies. Our patent position is generally uncertain and involves complex legal and factual questions.

In the U.S., our patents have expected expiration dates between 2023 and 2041. In 2021, several patents covering technology included in our
Products  expired  in  the  U.S.  and  elsewhere.  Patent  expiration  could  adversely  affect  our  ability  to  protect  our  Products  and  future  product
development  and  our  competitors  may  develop  and  market  competing  products.  We  have  also  filed  additional  patent  applications  in  several
countries  that  may  never  be  issued.  Consequently,  our  operating  results  and  financial  position  could  be  materially  adversely  affected.  In
addition, due to the extensive time needed to develop, test and obtain regulatory approval for our treatment therapies, any patents

43

that protect our Product candidates may expire early during commercialization. This may reduce or eliminate any market advantages that such
patents may give us and harm our financial position. If we fail to develop and successfully launch new Products prior to the expiration of patents
for our existing Products, our sales and achieving patient acceptance with respect to those Products could decline significantly. We may not be
able to develop and successfully launch more advanced replacement Products before these and other patents expire.

We  have  limited  intellectual  property  rights  outside  of  our  key  markets.  In  some  countries  outside  the  U.S.,  we  do  not  have  any  intellectual
property  rights,  and  our  intellectual  property  rights  in  other  countries  outside  the  U.S.  have  a  different  scope  and  strength  compared  to  our
intellectual property rights in the U.S. Consequently, we may not be able to prevent third parties from practicing our inventions in all countries
outside  the  U.S.  Competitors  may  use  our  technologies  in  jurisdictions  where  we  have  not  obtained  patent  protection  to  develop  their  own
products and further, may export otherwise infringing products to territories where we have patent protection, but where enforcement rights are
not as strong as those in the U.S. These products may compete with our devices, and our patents or other intellectual property rights may not
be effective or adequate to prevent such competition.

For  a  variety  of  reasons,  we  may  decide  not  to  file  for  patent  protection  for  certain  of  our  intellectual  property.  Our  patent  rights  underlying
TTFields  and  our  Products  may  not  be  adequate,  and  our  competitors  or  customers  may  design  around  our  proprietary  technologies  or
independently develop similar or alternative technologies or products that are equal or superior to ours without infringing on any of our patent
rights. In addition, the patents licensed or issued to us may not provide a competitive advantage, and may be insufficient to prevent others from
commercializing  products  similar  or  identical  to  ours.  The  occurrence  of  any  of  these  events  could  have  a  material  adverse  effect  on  our
business, prospects, financial condition and results of operations and cause our stock price to decline.

Our existing and future patent portfolio also may be vulnerable to legal challenges worldwide. The standards that courts use to interpret patents
are not always applied predictably or uniformly and can change from country to country, particularly as new technologies develop. As a result of
the uncertainties of patent law in general, we cannot predict how much protection, if any, will be given to our patents if we attempt to enforce
them and they are challenged in court. Any attempt to enforce our intellectual property rights may also be time-consuming and costly, may divert
the attention of management from our business, may ultimately be unsuccessful or may result in a remedy that is not commercially valuable.
Such  attempts  may  also  provoke  third  parties  to  assert  claims  against  us  or  result  in  our  intellectual  property  being  narrowed  in  scope  or
declared to be invalid or unenforceable.

In addition, we rely on certain proprietary trade secrets, know-how and other confidential information. We have taken measures to protect our
unpatented  trade  secrets,  know-how  and  other  confidential  information,  including  the  use  of  confidentiality  and  assignment  of  inventions
agreements with our employees, consultants and certain contractors. It is possible, however, that these persons may breach or challenge the
agreements, that our trade secrets may otherwise be misappropriated or that competitors may independently develop or otherwise discover our
trade secrets. There is therefore no guarantee that we will be able to obtain, maintain and enforce the intellectual property rights that may be
necessary to protect and grow our business and to provide us with a meaningful competitive advantage, and our failure to do so could have a
material adverse effect on our business, prospects, financial condition and results of operations and cause our stock price to decline.

The oncology and medical device industries are characterized by patent and other intellectual property litigation and disputes, and
any litigation, dispute or claim against us may cause us to incur substantial costs, could place a significant strain on our financial
resources, divert the attention of management from our business, harm our reputation and require us to remove certain devices from
the market.

Whether a product infringes a patent or violates other intellectual property rights involves complex legal and factual issues, the determination of
which is often uncertain. Any intellectual property dispute, even a meritless or unsuccessful one, would be time consuming and expensive to
defend  and  could  result  in  the  diversion  of  our  management’s  attention  from  our  business  and  result  in  adverse  publicity,  the  disruption  of
research and development and marketing efforts, injury to our reputation and loss of revenues. Any of these events could negatively affect our
business, prospects, financial condition and results of operations.

Third  parties  may  assert  that  TTFields,  our  Products,  the  methods  employed  in  the  use  of  our  Products  or  other  activities  infringe  on  their
patents.  Such  claims  may  be  made  by  competitors  seeking  to  obtain  a  competitive  advantage  or  by  other  parties,  many  of  whom  have
significantly  larger  intellectual  property  portfolios  than  we  have.  Additionally,  in  recent  years,  individuals  and  groups  have  begun  purchasing
intellectual property assets for the purpose of making claims of infringement and attempting to extract settlements from companies like ours.
With respect to our current Products, the risk of infringement claims is exacerbated by the fact that there are numerous

44

issued and pending patents relating to the treatment of cancer. Because patent applications can take many years to issue, and in many cases
remain unpublished for many months after filing, there may be applications now pending of which we are unaware that may later result in issued
patents that our Products may infringe.

There could also be existing patents that one or more components of our Products or other device candidates may inadvertently infringe. As the
number  of  competitors  in  the  market  or  other  device  candidates  grows,  the  possibility  of  inadvertent  patent  infringement  by  us  or  a  patent
infringement claim against us increases. To the extent we gain greater market visibility, our risk of being subject to such claims is also likely to
increase. If a third party’s patent was upheld as valid and enforceable and we were found to be infringing, we could be prevented from making,
using, selling, offering to sell or importing our Products or other device candidates, unless we were able to obtain a license under that patent or
to redesign our systems to avoid infringement. A license may not be available at all or on terms acceptable to us, and we may not be able to
redesign our Products to avoid any infringement. Modification of our Products or development of device candidates to avoid infringement could
require  us  to  conduct  additional  clinical  studies  and  to  revise  our  filings  with  the  FDA  and  other  regulatory  bodies,  which  would  be  time-
consuming and expensive. If we are not successful in obtaining a license or redesigning our devices, we may be unable to make, use, sell, offer
to  sell  or  import  our  devices  and  our  business  could  suffer.  We  may  also  be  required  to  pay  substantial  damages  and  undertake  remedial
activities, which could cause our business to suffer.

We may also be subject to claims alleging that we infringe or violate other intellectual property rights, such as copyrights or trademarks, may
have to defend against allegations that we misappropriated trade secrets, and may face claims based on competing claims of ownership of our
intellectual property. The confidentiality and assignment of inventions agreements that our employees, consultants and other third parties sign
may  not  in  all  cases  be  enforceable  or  sufficient  to  protect  our  intellectual  property  rights.  In  addition,  we  may  face  claims  from  third  parties
based on competing claims to ownership of our intellectual property.

We also employ individuals who were previously employed at other medical device companies, and as such we may be subject to claims that
such  employees  have  inadvertently  or  otherwise  used  or  disclosed  the  alleged  trade  secrets  or  other  proprietary  information  of  their  former
employers.  Any  such  litigation,  dispute  or  claim  could  be  costly  to  defend  and  could  subject  us  to  substantial  damages,  injunctions  or  other
remedies, which could have a material adverse effect on our business, prospects, financial condition and results of operations and cause our
stock price to decline.

Changes in U.S. patent law could diminish the value of patents in general, thereby impairing our ability to protect our devices.

As is the case with other medical device companies, our success is heavily dependent on our intellectual property rights, and particularly on our
patent rights. Obtaining and enforcing patents in the medical device industry involves both technological and legal complexity, and is therefore
costly, time consuming and inherently uncertain. In addition, the U.S. has recently enacted and is currently implementing wide-ranging patent
reform  legislation.  Certain  U.S.  Supreme  Court  rulings  have  narrowed  the  scope  of  patent  protection  available  in  certain  circumstances  and
weakened the rights of patent owners in certain situations. In addition to increasing uncertainty with regard to our ability to obtain patents in the
future, this combination of events has created uncertainty with respect to the value of patents once obtained. Depending on decisions by the
U.S. Congress, the federal courts and the USPTO, the laws and regulations governing patents could change in unpredictable ways that could
further negatively impact the value of our patents, narrow the scope of available patent protection or weaken the rights of patent owners.

Risks relating to our ordinary shares and capital structure

The market price for our ordinary shares may be volatile, which could result in substantial losses.

The market price for our ordinary shares may be volatile and subject to wide fluctuations in response to factors such as publication of clinical
studies relating to our Products, our system candidates or a competitor’s product, actual or anticipated fluctuations in our quarterly results of
operations,  changes  in  financial  estimates  by  securities  research  analysts,  negative  publicity,  studies  or  reports,  changes  in  the  economic
performance or market valuations of other companies that operate in our industry, changes in the availability of third-party reimbursement in the
U.S. or other countries, changes in governmental regulations or in the status of our regulatory approvals or applications, announcements by us
or our competitors of material acquisitions, strategic partnerships, joint ventures or capital commitments, intellectual property litigation, release
of transfer restrictions on our outstanding ordinary shares, and economic or political conditions in the U.S. or elsewhere.

Our ordinary shares are issued under the laws of Jersey, which may not provide the level of legal certainty and transparency afforded
by incorporation in a U.S. state.

We  are  incorporated  under  the  laws  of  the  Bailiwick  of  Jersey,  Channel  Islands.  Jersey  legislation  regarding  companies  is  largely  based  on
English corporate law principles. However, there can be no assurance that Jersey law will not change in the future or that it will serve to protect
investors in a similar fashion afforded under corporate law principles in the U.S., which could adversely affect the rights of investors.

U.S. shareholders may not be able to enforce civil liabilities against us.

We are a Jersey entity with most of our assets located outside of the U.S. Although we have appointed an agent for service of process in the
U.S.  for  purposes  of  U.S.  federal  securities  laws,  a  number  of  our  directors  and  executive  officers  and  a  number  of  directors  of  each  of  our
subsidiaries are not residents of the U.S., and all or a substantial portion of the assets of such persons are located outside the U.S. As a result,
it  may  not  be  possible  for  investors  to  effect  service  of  process  within  the  U.S.  upon  such  persons  or  to  enforce  against  them  judgments
obtained in U.S. courts predicated upon the civil liability provisions of the federal securities laws of the U.S.

We have been advised by our Jersey lawyers that the courts of Jersey would recognize any final and conclusive judgment under which a sum of
money is payable (not being a sum payable in respect of taxes or other charges of a like nature or in respect of a fine or other penalty) obtained
against  us  in  the  courts  of  any  other  territory  in  respect  of  certain  enforceable  obligations  in  accordance  with  the  principles  of  private
international law as applied by Jersey law (which are broadly similar to the principles accepted under English common law) and such judgment
would be sufficient to form the basis of proceedings in the Jersey courts for a claim for liquidated damages in the amount of such judgment. In
such proceedings, the Jersey courts would not re-hear the case on its merits save in accordance with such principles of private international
law.  Obligations  may  not  necessarily  be  enforceable  in  Jersey  in  all  circumstances  or  in  accordance  with  their  terms;  and  in  particular,  but
without limitation: (i) any agreement purporting to provide for a payment to be made in the event of a breach of such agreement would not be
enforceable  to  the  extent  that  the  Jersey  courts  were  to  construe  such  payment  to  be  a  penalty  that  was  excessive,  in  that  it  unreasonably
exceeds the maximum damages that an obligee could have suffered as a result of the breach of an obligation; (ii) the Jersey courts may refuse
to give effect to any provision in an agreement that would involve the enforcement of any revenue or penal laws in other jurisdictions; and (iii)
the  Jersey  courts  may  refuse  to  allow  unjust  enrichment  or  to  give  effect  to  any  provisions  of  an  agreement  (including  provisions  relating  to
contractual interest on a judgment debt) that it considers usurious.

We have borrowed a significant amount of debt and have the ability to borrow additional debt in the future, which could adversely
affect our financial condition and results of operations and our ability to react to changes in our business.

We  currently  have  two  significant  debt  arrangements  outstanding.  On  November  5,  2020,  we  issued  $575  million  of  0%  Convertible  Senior
Notes due 2025 (the “Convertible Notes”). The Convertible Notes are senior unsecured obligations. The Convertible Notes do not bear regular
interest,  and  mature  on  November  1,  2025,  unless  earlier  repurchased,  redeemed  or  converted.  The  Notes  are  not  redeemable  prior  to
November  6,  2023  and  are  convertible  into  a  combination  of  cash  and  ordinary  shares  on  or  after  August  1,  2025,  or  earlier  upon  certain
events.

Our existing indebtedness and any additional indebtedness we may incur otherwise could require us to divert funds identified for other purposes
for debt service and impair our liquidity position.

The  fact  that  a  substantial  portion  of  our  cash  flow  from  operations  could  be  needed  to  make  payments  on  our  indebtedness  could  have
important consequences, including the following:

•

•

•

•

increasing our vulnerability to general adverse economic and industry conditions or increased interests rates;

limiting the availability of our cash flow for other purposes and our flexibility in planning for or reacting to changes in our business and
the markets in which we operate, which would place us at a competitive disadvantage compared to our competitors that may have less
exposure to debt;

limiting our ability to borrow additional funds for working capital, capital expenditures and other investments; and

failing  to  comply  with  the  covenants  in  our  debt  agreements  could  result  in  all  of  our  indebtedness  becoming  immediately  due  and
payable.

46

Our ability to obtain necessary funds through borrowing, as well as our ability to service our indebtedness, will depend on our ability to generate
cash flow from operations. Our ability to generate cash is subject to general economic, financial, competitive, legislative, regulatory and other
factors  that  are  beyond  our  control.  If  our  business  does  not  generate  sufficient  cash  flow  from  operations  or  if  future  borrowings  are  not
available  to  us  under  our  outstanding  borrowings  or  otherwise  in  amounts  sufficient  to  enable  us  to  fund  our  liquidity  needs,  our  financial
condition and results of operations may be adversely affected. Our inability to make scheduled payments on our debt obligations in the future
would require us to refinance all or a portion of our indebtedness on or before maturity, sell assets or seek additional equity investment. We may
not be able to take any of such actions on a timely basis, on terms satisfactory to us or at all.

Transactions relating to our Convertible Notes may dilute the ownership interest of existing shareholders, or may otherwise depress
the price of our ordinary shares.

The conversion of some or all of our Convertible Notes would dilute the ownership interests of existing shareholders to the extent we deliver
shares upon conversion of any of such notes. Our Convertible Notes are convertible at the option of their holders prior to their scheduled terms
under  certain  circumstances.  In  connection  with  the  conversion  of  our  Convertible  Notes,  we  may  deliver  to  the  holders  of  such  notes  a
significant number of our ordinary shares. Any sales in the public market of our ordinary shares issuable upon such conversion could adversely
affect prevailing market prices of our ordinary shares. In addition, the existence of our Convertible Notes may encourage short selling by market
participants  because  the  conversion  of  such  notes  could  be  used  to  satisfy  short  positions,  or  anticipated  conversion  of  such  notes  into  our
ordinary shares could depress the price of our ordinary shares.

ITEM 2.  PROPERTIES

Our  global  headquarters  and  operating  center  is  located  in  Root,  Switzerland,  our  U.S.  operating  center  is  located  in  Portsmouth,  New
Hampshire, and our research and development operations are located in Haifa, Israel, all of which are leased. In December 2021 we acquired a
property in downtown Portsmouth, New Hampshire that will become our U.S. flagship location. Construction on the property is expected to be
completed in 2023. We also lease additional office and warehouse space across North America, Europe, Israel and Japan. We believe that our
current facilities are adequate for our present purposes, but we may need additional space as we continue to grow and expand our operations.
We  believe  that  suitable  additional  or  alternative  office,  laboratory,  and  manufacturing  space  would  be  available  as  required  in  the  future  on
commercially reasonable terms.

ITEM 3.  LEGAL PROCEEDINGS

From  time  to  time,  we  are  involved  in  various  legal  proceedings,  claims,  investigations  and  litigation  that  arise  in  the  ordinary  course  of  our
business.  Litigation  is  inherently  uncertain.  Accordingly,  we  cannot  predict  with  certainty  the  outcome  of  these  matters.  After  considering  a
number of factors, including (but not limited to) the views of legal counsel, the nature of contingencies to which the Company is subject and
prior  experience,  management  believes  that  the  ultimate  disposition  of  these  legal  actions  will  not  materially  affect  its  consolidated  financial
position or results of operations.

ITEM 7. MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

Management’s Discussion and Analysis of Financial Condition and Results of Operations ("MD&A") is intended to provide information to assist
you  in  better  understanding  and  evaluating  our  financial  condition  and  results  of  operations.  We  encourage  you  to  read  this  MD&A  in
conjunction with our consolidated financial statements and the notes thereto included in Part II, Item 8 of this Annual Report on Form 10-K. This
discussion  contains  forward-looking  statements  that  involve  risks  and  uncertainties.  Please  refer  to  the  information  under  the  heading
"Cautionary  Note  Regarding  Forward-Looking  Statements"  elsewhere  in  this  report.  References  to  the  words  "we,"  "our,"  "us,"  and  the
"Company" in this report refer to NovoCure Limited, including its consolidated subsidiaries.

Overview

We are a global oncology company with a proprietary platform technology called Tumor Treating Fields ("TTFields"), which are electric fields
that exert physical forces to kill cancer cells via a variety of mechanisms. Our key priorities are to drive commercial adoption of Optune and
Optune Lua, our commercial TTFields devices, and to advance clinical and product development programs intended to extend overall survival
in some of the most aggressive forms of cancer.

Optune  is  approved  by  the  U.S.  Food  and  Drug  Administration  ("FDA")  under  the  Premarket  Approval  ("PMA")  pathway  for  the  treatment  of
adult patients with newly diagnosed glioblastoma ("GBM") together with temozolomide, a chemotherapy drug, and for adult patients with GBM
following  confirmed  recurrence  after  chemotherapy  as  monotherapy  treatment.  We  also  have  a  CE  certificate  to  market  Optune  for  the
treatment of GBM in the European Union ("EU"), as well as approval or local registration in the United Kingdom ("UK"), Japan, Canada and
certain other countries. Optune Lua is approved by the FDA under the Humanitarian Device Exemption ("HDE") pathway to treatment malignant
pleural mesothelioma ("MPM") together with standard chemotherapies. We have also received CE certification in the EU and approval or local
registration to market Optune Lua in certain other countries. We market Optune and Optune Lua in multiple countries around the globe with the
majority of our revenues coming from the use of Optune in the U.S., Germany and Japan. We are actively evaluating opportunities to expand
our international footprint.

We  believe  the  physical  mechanisms  of  action  behind  TTFields  therapy  may  be  broadly  applicable  to  solid  tumor  cancers.  We  recently
completed patient follow-up and announced top line results from our pivotal LUNAR study evaluating the use of TTFields in the treatment of
non-small cell lung cancer ("NSCLC") together with standard therapies. Patients treated with TTFields and standard therapies demonstrated a
statistically significant and clinically meaningful improvement in overall survival over standard therapies alone. The LUNAR study also showed a
statistically  significant  and  clinically  meaningful  improvement  in  overall  survival  when  patients  were  treated  with  TTFields  and  immune
checkpoint  inhibitors,  as  compared  to  those  treated  with  immune  checkpoint  inhibitors  alone,  and  a  positive  trend  in  overall  survival  when
patients  were  treated  with  TTFields  and  docetaxel  versus  docetaxel  alone.  We  expect  to  present  full  results  of  the  LUNAR  study  at  a  future
medical conference.

In  addition  to  the  LUNAR  study,  we  are  conducting  pivotal  studies  evaluating  the  use  of  TTFields  in  the  treatment  of  ovarian  cancer,  brain
metastases  from  NSCLC  ("brain  metastases")  and  pancreatic  cancer.  We  are  also  conducting  a  pivotal  study  testing  the  potential  survival
benefit of initiating Optune concurrent with radiation therapy versus following radiation therapy in patients with newly diagnosed GBM.

We have one ongoing pilot study evaluating the use of TTFields in the treatment of stage 3 NSCLC and are designing several additional pilot
and  pivotal  studies  in  partnership  with  oncology  leaders  to  further  explore  the  capabilities  of  TTFields.  We  anticipate  expanding  our  clinical
pipeline  over  time  to  study  the  safety  and  efficacy  of  TTFields  for  additional  solid  tumor  indications  and  combinations  with  other  cancer
treatment modalities.

The table below presents the current status of the ongoing clinical studies in our pipeline and anticipated timing of data.

51

Our  therapy  is  delivered
through a medical device and we continue to advance our Products with the intention to extend survival and maintain quality of life for patients.
We have several product development programs underway that are designed to optimize TTFields delivery to the target tumor and enhance
patient  ease  of  use.  Our  intellectual  property  portfolio  contains  hundreds  of  issued  patents  and  numerous  patent  applications  pending
worldwide. We believe we possess global commercialization rights to our Products in oncology and are well-positioned to extend those rights
into the future as we continue to find innovative ways to improve our Products.

In 2018, we granted Zai Lab (Shanghai) Co., Ltd. ("Zai") a license to commercialize Optune in China, Hong Kong, Macau and Taiwan ("Greater
China") under a License and Collaboration Agreement (the "Zai Agreement"). The Zai Agreement also establishes a development partnership
intended  to  accelerate  the  development  of  TTFields  in  multiple  solid  tumor  cancer  indications.  For  additional  information,  see  Note  12  to  the
Consolidated Financial Statements.

Impact of COVID-19

In  March  2020,  the  World  Health  Organization  (“WHO”)  declared  COVID-19  a  global  pandemic.  Since  the  pandemic  began,  we  have  been
following the guidance of the WHO, the U.S. Centers for Disease Control and Prevention, and local health authorities in all of our active markets
and we have adjusted the way we conduct business to adapt to the evolving situation. The COVID-19 pandemic did not have a material impact
on our financial results throughout 2022. The pandemic has had and is having an impact on our day-to-day operations, which varies by region
based on factors such as geographical spread, stage of containment and recurrence of the pandemic in each region. We believe the prolonged
disruption caused by COVID-19 is resulting in increased volatility across global health care systems, such as fluctuations in patient volumes and
changes in patterns of care in certain regions, which is currently impacting and might continue to impact our business and clinical studies in the
future.  For  example,  outside  the  U.S.,  localized  lockdowns  are  causing  disruptions  in  the  ability  to  monitor  clinical  studies.  TTFields  is  an
emerging modality in cancer care and requires significant educational effort to drive awareness and acceptance of our therapy. We have relied
heavily on virtual engagement to manage these educational efforts since the onset of the pandemic, which poses challenges to our ability to
effectively communicate and engage with our customers and partners around the world.

Given the aggressive nature of the cancers that we treat, we believe that the fundamental value proposition of the TTFields platform remains
unchanged. We continue to evaluate and plan for the potential effects of COVID-19 on our business moving forward. The extent to which the
COVID-19 pandemic may impact our business and clinical studies in the future will depend on further developments, which are highly uncertain
and  cannot  be  predicted  with  confidence.  The  COVID-19  pandemic  may  also  heighten  many  of  the  other  risks  described  in  our  risk  factors
disclosed in this Annual Report.

We  view  our  operations  and  manage  our  business  in  one  operating  segment.  Our  net  revenues  were  $537.8  million  for  the  year  ended
December 31, 2022, $535.0 million for the year ended December 31, 2021 and $494.4 million for the year ended December 31, 2020. Our net
loss  was  $92.5  million  for  the  year  ended  December  31,  2022,  net  loss  was  $58.4  million  for  the  year  ended  December  31,  2021  and  net
income was $19.8 million for the year ended December 31, 2020. As of December 31, 2022, we had an accumulated deficit of $778.5 million.

Commentary on Results of Operations

Net revenues

Our  revenues  are  primarily  derived  from  patients  using  our  Products  in  our  active  markets.  We  charge  for  treatment  with  our  Products  on  a
monthly  basis.  Our  potential  net  revenues  per  patient  are  determined  by  our  ability  to  secure  payment,  the  monthly  fee  we  collect  and  the
number of months that the patient remains on therapy.

We  also  receive  revenues  pursuant  to  the  Zai  Agreement.  For  additional  information  regarding  the  Zai  Agreement,  see  Note  12  to  the
Consolidated Financial Statements.

Cost of revenues

We contract with third parties to manufacture our Products. Our cost of revenues is primarily comprised of the following:

•

•

•

disposable arrays;

depreciation expense for the field equipment, including the electric field generator used by patients; and

personnel and overhead costs such as facilities, freight and depreciation of property, plant and equipment associated with managing
our inventory, warehousing and order fulfillment functions.

Operating expenses

Our operating expenses consist of research, development and clinical studies, sales and marketing and general and administrative expenses.
Personnel costs are a significant component for each category of operating expenses and consist of wages, benefits and bonuses. Personnel
costs also include share-based compensation.

Research, development and clinical studies

Our research, development and clinical studies activity is focused on advancing TTFields through clinical studies across multiple solid tumor
types and improving the efficacy and usability of our devices. Research, development and clinical studies costs, including direct and allocated
expenses, are expensed as incurred and consist primarily of the following:

•

•

personnel  costs  for  those  employees  involved  in  our  preclinical  and  basic  research,  clinical  development  programs,  clinical  affairs,
product development and regulatory activities;

costs to conduct research, product development and clinical study activity through agreements with contract research organizations and
other third parties;

• manufacturing expenses associated with our Products, including durable components and disposable arrays, utilized in clinical studies

and other research;

•

•

•

costs associated with medical grants, publications, presentations and investigator-sponsored trials;

professional fees related to regulatory approvals and conformity assessment procedures; and

facilities, depreciation and other allocated expenses, which include direct and allocated expenses for rent and maintenance of facilities,
depreciation of leasehold improvements and equipment and laboratory and other supplies.

We are committed to investing strategically to maximize the growth potential of the TTFields platform. We expect growth in our research and
development  investments  to  continue  into  2023  as  we  work  to  advance  our  pipeline  programs  and  increase  acceptance  of  Tumor  Treating
Fields across the global oncology community.

Sales and marketing

Sales and marketing expenses consist primarily of personnel costs, travel, marketing and promotional activities, medical education, commercial
shipping  and  facilities  costs.  Over  the  next  few  years,  we  expect  to  continue  to  make  significant  expenditures  associated  with  selling  and
marketing our Products, primarily in connection with continued commercialization in North America, the EU and Japan for the treatment of our
approved indications.

General and administrative

General and administrative expenses consist primarily of personnel, professional fees and facilities costs. General and administrative personnel
costs include our executive, finance, human resources, information technology and legal functions. These costs also include our contributions to
support industry and patient groups. Our professional fees consist primarily of accounting, information technology, legal and other consulting
costs.  We  expect  that  general  and  administrative  expenses  will  increase  to  support  our  growth.  In  addition,  we  incur  significant  legal  and
accounting  costs  related  to  compliance  with  SEC  rules  and  regulations,  including  the  costs  of  achieving  and  maintaining  compliance  with
Section  404  of  the  Sarbanes-Oxley  Act  of  2002  and  compliance  with  rules  of  the  NASDAQ  Stock  Market,  as  well  as  insurance,  investor
relations and other costs associated with being a public company.

Financial expenses, net

Financial expenses, net primarily consists of credit facility interest expense and related debt issuance costs, interest income from cash balances
and short-term investments and gains (losses) from foreign currency transactions. Our reporting currency is the U.S. dollar. We have historically
held substantially all of our cash balances in U.S. dollar denominated accounts to minimize the risk of translational currency exposure.

54

Critical accounting policies and estimates

In  accordance  with  U.S.  GAAP,  in  preparing  our  financial  statements  we  must  make  estimates  and  assumptions  that  affect  the  reported
amounts of assets and liabilities, the disclosure of contingent assets and liabilities as of the date of the financial statements and the reported
amounts  of  net  revenues  and  expenses  during  the  reporting  period.  We  develop  and  periodically  change  these  estimates  and  assumptions
based on historical experience and on various other factors that we believe are reasonable under the circumstances. Actual results may differ
from these estimates.

The  critical  accounting  policies  requiring  estimates,  assumptions  and  judgments  that  we  believe  have  the  most  significant  impact  on  our
consolidated financial statements are described below.

Revenue recognition

In  May  2014,  the  Financial  Accounting  Standards  Board  ("FASB")  issued  Accounting  Standards  Update  ("ASU")  2014-09,  Revenue  from
Contracts with Customers (Topic 606) (ASU 2014-09), an updated standard on revenue recognition and issued subsequent amendments to the
initial guidance in March 2016, April 2016, May 2016 and December 2016 within ASU 2016-08, 2016-10, 2016-12 and 2016-20, respectively.
The Company adopted the standard effective January 1, 2018 using the modified retrospective method for all contracts. The reported results for
2018  and  thereafter  reflect  the  application  of  Accounting  Standards  Codification  ("ASC")  606  guidance.  The  amount  of  revenue  recognized
reflects the consideration to which we expect to be entitled to receive in exchange for our Products. For additional information, see Note 2(m) to
the Consolidated Financial Statements.

We  also  receive  revenues  pursuant  to  the  Zai  Agreement.  For  additional  information  regarding  the  Zai  Agreement,  see  Note  12  to  the
Consolidated Financial Statements.

Share-based compensation

Under the FASB's ASC 718, Compensation-Stock Compensation, we measure and recognize compensation expense for share options granted
to our employees and directors and for our ESPP based on the fair value of the awards on the date of grant. The fair value of share options is
estimated  at  the  date  of  grant  using  the  Black-Scholes  option  pricing  model  and  for  market  condition  awards  we  also  use  the  Monte-Carlo
simulation model. Both models requires management to apply judgment and make estimates, including:

•

•

•

•

beginning with the first quarter of 2022, the computation of expected volatility is based on the historical volatility the Company's shares,
beginning  with  the  first  quarter  of  2021  and  prior  to  the  first  quarter  of  2022,  the  computation  of  expected  volatility  is  based  on  a
combination of actual historical share price volatility of comparable publicly-traded companies and the historical volatility the Company's
shares. Prior to the first quarter of 2021, due to the lack of sufficient historical information for the Company, the computation was based
on actual historical volatility of comparable publicly-traded companies;

beginning with the first quarter of 2021, the expected term of options granted is calculated using the Company's historical and future
exercise behavior. Prior to the first quarter of 2021, it was calculated using the average between the vesting period and the contractual
term to the expected term of the options in effect at the time of grant;

the risk-free interest rate, which we base on the yield curve of U.S. Treasury securities with periods commensurate with the expected
term of the options being valued; and

the  expected  dividend  yield,  which  we  estimate  to  be  zero  based  on  the  fact  that  we  have  never  paid  cash  dividends  and  have  no
present intention to pay cash dividends.

For information about our ESPP, see Note 14 to the Consolidated Financial Statements.

We recognize share-based compensation costs only for those shares expected to vest over the requisite vesting period of the award, which is
generally the option vesting term of four years, using the accelerated method.

We recognize compensation costs for the value of performance stock units ("PSU") over the performance period when the vesting conditions
become probable in accordance with ASC 718.

The table below summarizes the assumptions that were used to estimate the fair value of the options granted to employees during the periods
presented:

If any of the assumptions used in the Black-Scholes option pricing model change significantly, share-based compensation for future awards may
differ materially from the awards granted previously.

So  long  as  our  ordinary  shares  are  publicly  traded  in  a  liquid  market,  we  will  rely  on  the  daily  trading  price  of  our  ordinary  shares  when  we
estimate the fair value of options granted.

We incurred share-based compensation expense of $107.0 million, $94.9 million and $75.7 million during the years ended December 31, 2022,
2021 and 2020, respectively. As of December 31, 2022, we have unrecognized compensation expense of $125.6 million, which is expected to
be recognized over a weighted average period of approximately 2.38 years. We expect to continue to grant equity awards in the future, and to
the extent that we do, our recognized share-based compensation expense will likely increase. For additional information, see Note 14 to the
Consolidated Financial Statements.

Long-lived assets

Property and equipment and field equipment are stated at cost, net of accumulated depreciation. Depreciation is calculated using the straight-
line method over the estimated useful life of the relevant asset. We make estimates of the useful life of our property and equipment and field
equipment,  based  on  similar  assets  purchased  in  the  past  and  our  historical  experience  with  such  similar  assets,  in  order  to  determine  the
depreciation expense to be recorded for each reporting period.

Our field equipment consists of equipment being utilized under rental agreements accounted for on a monthly basis as an operating lease, as
well as service pool equipment. Service pool equipment is equipment owned and maintained by us that is swapped for equipment that needs
repair or maintenance by us while being used by a patient. We record a provision for any excess, lost or damaged equipment when warranted
based on an assessment of the equipment.

We  assess  impairment  whenever  events  or  changes  in  circumstances  indicate  that  the  carrying  amount  of  the  asset  is  impaired  or  the
estimated useful life is no longer appropriate. Circumstances such as changes in technology or in the way an asset is being used may trigger an
impairment review. For additional information, see Notes 2(i) and 2(j) to the Consolidated Financial Statements.

Inventories

Inventories  are  stated  at  the  lower  of  cost  or  net  realizable  value.  We  regularly  evaluate  the  ability  to  realize  the  value  of  inventory.  If  the
inventories are deemed damaged, if actual demand for our devices declines, or if market conditions are less favorable than those projected,
inventory write-offs may be required. For additional information, see Note 2(h) to the Consolidated Financial Statements.

Income taxes

As  part  of  the  process  of  preparing  our  consolidated  financial  statements,  we  are  required  to  calculate  our  income  taxes  based  on  taxable
income by jurisdiction. We make certain estimates and judgments in determining our income taxes, including assessment of our uncertain tax
positions, for financial statement purposes. Significant changes to these estimates may result in an increase or decrease to our tax provision in
the subsequent period when such a change in estimate occurs.

Uncertain  tax  positions  are  based  on  estimates  and  assumptions  that  have  been  deemed  reasonable  by  management.  Our  estimates  of
unrecognized tax benefits and potential tax benefits may not be representative of actual outcomes.

For additional information, see Note 13 to the Consolidated Financial Statements.

We believe certain commercial operating statistics are useful to investors in evaluating our commercial business as they help investors evaluate
and compare the adoption of our Products from period to period. The number of active patients on therapy is our principal revenue driver. An
"active patient" is a patient who is receiving treatment under a commercial prescription order as of the measurement date, including patients
who may be on a temporary break from treatment and who plan to resume treatment in less than 60 days. Prescriptions are a leading indicator
of

57

 
demand. A "prescription received" is a commercial order for Optune or Optune Lua that is received from a physician certified to treat patients
with our Products for a patient not previously on Optune or Optune Lua. Orders to renew or extend treatment are not included in this total.

Net revenues. Net revenues increased by $2.8 million, or 1%, to $537.8 million for the year ended December 31, 2022 from $535.0 million for
the year ended December 31, 2021. This was primarily due to an increase in collections from previously denied and appealed claims in the U.S.
offset by a reduction in German approval rates as a result of updated coverage criteria, and the impact of foreign exchange rate fluctuations.

In 2022, we recorded $32 million in revenue from the successful appeal of previously denied claims for Medicare fee-for-service beneficiaries
billed  prior  to  established  coverage.  We  continue  to  actively  appeal  and  pursue  previously  denied  claims  for  beneficiaries  billed  prior  to
established coverage, but the cadence and amount of these Medicare payments are impossible to predict. We believe collections from those
claims which were most accessible were largely exhausted in 2022 and the remaining outstanding claims will take time to collect. As a result,
we expect future net revenue to more closely reflect core drivers of net revenue: number of active patients on therapy, duration of therapy, and
net realized price per month.

Cost of revenues. Our cost of revenues were $114.9 million for the year ended December 31, 2022, virtually unchanged from $114.9 million for
the year ended December 31, 2021. Excluding sales to Zai, cost of revenues per

58

 
 
 
active patient per month were $2,481 for the year ended December 31, 2022 compared to $2,474 for the year ended December 31, 2021.

Cost  of  revenues  per  active  patient  is  calculated  by  dividing  the  cost  of  revenues  for  the  year  less  product  sales  to  Zai  for  the  year  by  the
average of the active patients at the end of the each quarter in the current year and the end of the year active patients from the prior year. This
annual figure is then divided by twelve to estimate the monthly cost of revenues per active patient. Sales to Zai are deducted because they are
made at burdened cost and in anticipation of future royalties from Zai, and Zai patient counts are not included in our active patient population.
Product's  cost  sold  to  Zai  totaled  $11.1  million  for  the  year  ended  December  31,  2022  compared  to  $11.3  million  for  the  year  ended
December 31, 2021.

Gross  margin  was  79%  for  the  year  ended  December  31,  2022  and  79%  for  the  year  ended  December  31,  2021.  Our  gross  margins  are
affected by our ability to achieve efficiencies of scale, the number of active patients and array usage within a given period, product mix, and
product modifications. Increased product sales to Zai have the effect of tempering gross margin, as those products are sold at cost.

Research, development and clinical studies expenses. Research, development and clinical studies expenses increased by $4.8 million, or 2%,
to $206.1 million for the year ended December 31, 2022 from $201.3 million for the year ended December 31, 2021. The change is driven by an
increase of $4.8 million in product development and regulatory affairs expenses.

We  expect  growth  in  our  research  and  development  investments  to  continue  into  2023  as  we  work  to  advance  our  pipeline  programs  and
increase  acceptance  of  TTFields  across  the  global  oncology  community.  We  balance  our  investments  in  research  and  development  with  our
organizational capacity to effectively execute our strategic initiatives.

Sales  and  marketing  expenses.  Sales  and  marketing  expenses  increased  by  $36.6  million,  or  27%,  to  $173.7  million  for  the  year  ended
December 31, 2022 from $137.1 million for the year ended December 31, 2021. The change primarily was due to increases of $22.7 million,
$2.9  million  and  $2.9  million  in  marketing,  health  policy,  and  sales  expenses,  respectively,  which  are  intended  to  increase  awareness  and
acceptance of TTFields in our approved indications and enhance our commercial capabilities in anticipation of potential future approvals in new
indications. Additionally, we are investing in market access capabilities in order to evaluate opportunities, identify optimal access pathways, and
successfully gain reimbursement in new geographies.

General  and  administrative  expenses.  General  and  administrative  expenses  increased  by  $6.6  million,  or  5%,  to  $132.8  million  for  the  year
ended  December  31,  2022  from  $126.1  million  for  the  year  ended  December  31,  2021.  The  change  primarily  was  due  to  increases  of  $5.0
million  and  $2.5  million  in  information  technology  infrastructure  and  supply  chain  optimization,  respectively,  and  offset  by  a  decrease  in
expenses associated with personnel costs and professional services.

December 31, 2022 compared to a tax expense of $6.3 million for the year ended December 31, 2021. The increase was primarily due to an
increase in income before taxes in the U.S.

Non-GAAP financial measures

We also measure our performance based upon a non-U.S. GAAP measurement of earnings before interest, taxes, depreciation, amortization
and  shared-based  compensation  ("Adjusted  EBITDA").  We  believe  Adjusted  EBITDA  is  useful  to  investors  in  evaluating  our  operating
performance because it helps investors evaluate and compare the results of our operations from period to period by removing the impact of
earnings attributable to our capital structure, tax rate and material non-cash items, specifically share-based compensation.

We calculate Adjusted EBITDA as operating income before financial expenses and income taxes, net of depreciation, amortization and share-
based  compensation.  The  following  table  reconciles  net  loss  (which  is  the  most  directly  comparable  U.S.  GAAP  operating  performance

Adjusted EBITDA decreased by $32.8 million, or 54%, to $28.1 million for the year ended December 31, 2022 from $60.8 million for the year
ended  December  31,  2021.  This  decrease  was  primarily  driven  by  an  increase  in  sales  and  marketing  expenses  intended  to  increase
awareness  and  acceptance  of  TTFields  in  our  approved  indications,  enhance  our  commercial  capabilities  in  anticipation  of  potential  future
approvals in new indications, and expand our international footprint.

Liquidity and capital resources

We have incurred significant losses and cumulative negative cash flows from operations with only limited and intermittent operating profits since
our  founding  in  2000.  As  of  December  31,  2022,  we  had  an  accumulated  deficit  of  $778.5  million.  To  date,  we  primarily  have  financed  our
operations through the issuance and sale of equity and the proceeds from long-term loans.

At  December  31,  2022,  we  had  $115.3  million  in  cash  and  cash  equivalents  and  $854.1  million  in  short-term  investments.  At  December  31,
2022, our cash, cash equivalents and short-term investments totaled $969.4 million, an increase of $31.7 million compared to $937.7 million at
December 31, 2021. The increase was primarily due to net cash generated by operating activities and the exercise of options.

We believe our cash, cash equivalents and short-term investments as of December 31, 2022 are sufficient for our operations for at least the
next 12 months based on our existing business plan and our ability to control the timing of significant expense commitments. We expect that our
research, development and clinical expenses, sales and marketing expenses and general and administrative expenses will continue to increase
over the next several years and may outpace our gross profit. As a result, we may need to raise additional capital to fund our operations.

Net cash provided by operating activities primarily represents our net income for the periods presented. Adjustments to net income for non-cash
items  include  share-based  compensation,  depreciation,  amortization  and  asset  write-downs.  Operating  cash  flows  are  also  impacted  by
changes  in  operating  assets  and  liabilities,  principally  trade  payables,  deferred  revenues,  other  payables,  prepaid  expenses,  inventory  and
trade receivables.

Net cash provided by operating activities was $30.8 million for the year ended December 31, 2022 compared to $82.8 million for the year ended
December  31,  2021  a  decrease  of  $  52.0  million.  The  decrease  in  net  cash  provided  by  operating  activities  was  primarily  driven  by  a  $43.2
million increase in sales, marketing, general and administrative expenses to enhance our capabilities in anticipation of potential future approvals
of new indications and entry into potential new markets, and a $4.8 million increase in research and development expenses. In addition, finance
income increased by $15.4 million and tax expenses increased by $ 4.4 million, offsetting a $2.8 million increase in gross profit and a $17.0
million change in working capital.

Upcoming use of cash in operations will include payments in the normal course of business of $42.1 million in purchase obligations with certain
of  our  suppliers,  primarily  for  the  purchase  of  Product  components  along  with  other  commitments  to  purchase  goods  or  services.  These
amounts include approximately $30.6 million of commitments with three major suppliers. We make such commitments through a combination of
purchase  orders,  supplier  contracts,  and  open  orders  based  on  projected  demand  information.  We  also  have  employment  agreements  with
certain employees that require the funding of a specific level of payments if certain events, such as a change in control or termination without
cause,  occur.  In  the  course  of  normal  business  operations,  we  also  have  agreements  with  contract  service  providers  to  assist  in  the
performance  of  our  research  and  development  (including  clinical  studies)  and  manufacturing  activities.  We  could  also  enter  into  additional
collaborative research, contract research, manufacturing and supplier agreements in the future, which may require up-front payments and even
long-term commitments of cash.

Investing activities

Our  investing  activities  primarily  consist  of  capital  expenditures  to  purchase  property  and  equipment  and  field  equipment,  as  well  as
investments in and redemptions of our short-term investments.

Net cash used in investing activities was $140.0 million for the year ended December 31, 2022 compared to net cash used in investing activities
of $144.8 million for the year ended December 31, 2021. The net cash used in investing activities for 2022 was primarily attributable to $21.4
million in property and equipment and the net purchase of $118.6 million in short-term investments. The net cash used in investing activities for
2021 was primary attributable to $24.2 million in property and equipment and the net purchase of $120.7 million in short-term investments.

Financing activities

To date, our primary financing activities have been the sale of equity and the proceeds from long-term loans.

Net cash provided by financing activities was $15.5 million for the year ended December 31, 2022 compared to $25.7 million for the year ended
December  31,  2021.  The  net  cash  provided  by  financing  activities  for  2022  was  primarily  attributable  to  $10.3  million  in  proceeds  from  the
exercise of options and $5.2 million in proceeds from the issuance of shares pursuant to the ESPP. The net cash provided by financing activities
for 2021 was primarily attributable to $21.2 million in proceeds from the exercise of options and $4.5 million in proceeds from the issuance of
shares pursuant to the ESPP.

Convertible Notes

On November 5, 2020, we issued $575.0 million aggregate principal amount of 0% Convertible Senior Notes due 2025 (the “Notes”). The net
proceeds from the offering were approximately $558.4 million. We intend to use the net proceeds to further advance our clinical and product
development programs and to invest in associated pre-commercial and commercial activities, as well as for general corporate purposes.

The  Notes  are  senior  unsecured  obligations.  The  Notes  do  not  bear  regular  interest,  and  the  principal  amount  of  the  Notes  will  not  accrete.
Special  interest,  if  any,  payable  in  accordance  with  the  terms  of  the  Notes  will  be  payable  in  cash  semi-annually  in  arrears  on  May  1  and
November  1  of  each  year,  beginning  on  May  1,  2021.  The  Notes  mature  on  November  1,  2025,  unless  earlier  repurchased,  redeemed  or
converted.

The Notes are convertible at an initial conversion rate of 5.9439 ordinary shares per $1,000 principal amount of the Notes, which is equivalent
to an initial conversion price of approximately $168.24 per ordinary share. In January 2021, we irrevocably elected to settle all conversions of
Notes  by  a  combination  of  cash  and  our  ordinary  shares  and  that  the  cash  portion  per  $1,000  principal  amount  of  Notes  for  all  conversion
settlements shall be $1,000, Accordingly, from and after the date of the election, upon conversion of any Notes, holders of Notes will receive,
with respect to each $1,000 principal amount of Notes converted, cash in an amount up to $1,000 and the balance of the conversion value, if
any, in our ordinary shares

The Notes are not redeemable prior to November 6, 2023, except in the event of certain tax law changes. We may redeem for cash all or any
portion of the Notes, at our option, on or after November 6, 2023 if the last reported sale price of our ordinary shares has been at least 130% of
the  conversion  price  then  in  effect  for  at  least  20  trading  days  (whether  or  not  consecutive)  during  any  30  consecutive  trading  day  period
(including the last trading day of such period) ending on, and including, the trading day immediately preceding the date on which we provide
notice of redemption at a redemption price equal to 100% of the principal amount of the Notes to be redeemed, plus accrued and unpaid special
interest, if any, to, but excluding, the redemption date. No sinking fund is provided for the Notes.

Prior to the close of business on the business day immediately preceding August 1, 2025, the Notes are convertible at the option of the holders
only  upon  the  satisfaction  of  certain  conditions  and  during  certain  periods  and  if  we  exercise  our  right  to  redeem  the  Notes  as  permitted  or
required by the indenture. On or after August 1, 2025 until the close of the business on the business day immediately preceding the maturity
date, holders may convert all or any portion of their Notes at the conversion rate at any time irrespective of the foregoing conditions.

Term loan credit facility

On November 6, 2020, we entered into a new three-year $150.0 million senior secured revolving credit facility with a syndicate of relationship
banks (the "2020 Credit Facility"). We may, subject to certain conditions and limitations, increase the revolving credit commitments outstanding
under the 2020 Credit Facility or incur new incremental term loans in an aggregate principal amount not to exceed $250.0 million in total.

The commitments under the 2020 Credit Facility are guaranteed by certain of our subsidiaries and secured by a first lien on our and certain of
our subsidiaries’ assets. Outstanding loans will bear interest per annum at a sliding scale based on the our secured leverage ratio from 2.75%
to  3.25%  above  the  applicable  interbank  borrowing  reference  rate  for  the  currency  in  which  the  loan  is  denominated.  Additionally,  the  2020
Credit Facility contains a fee for the unused revolving credit commitments at a sliding scale based on our secured leverage ratio from 0.35% to
0.45%. The 2020 Credit Facility contains financial covenants requiring maintenance of a minimum fixed charge coverage ratio and specifying a
maximum senior secured net leverage ratio, as well as customary events of default which include a change of control.

As of December 31, 2022, we had no outstanding balance borrowed under the 2020 Credit Facility.

On  February  17,  2023,  we  gave  irrevocable  notice  to  the  administrative  agent  under  the  2020  Credit  Facility  that  we  terminated  all
commitments, effective February 22, 2023. This effectively terminated the 2020 Credit Facility, as our ability to borrow and our obligations to
comply with all covenants ended on such date. The liens and guaranties in favor of the lenders are released. There are no early termination
fees payable and as of February 22, 2023 we had no outstanding balance borrowed under the 2020 Credit Facility.

2020 Prepayment of 2018 term loan

In 2018, we entered into a Loan and Security Agreement ("2018 Loan Agreement") pursuant to which we borrowed a term loan in the aggregate
principal  amount  of  $150  million  (the  "2018  Credit  Facility").  The  term  loan,  which  was  drawn  in  full  upon  execution  of  the  2018  Loan
Agreement,  bore  interest  at  9.0%  per  annum,  payable  quarterly  in  arrears.  In  2020,  we  terminated  the  2018  Credit  Facility  and  prepaid  the
principal amount in full. The prepayment

62

included $150 million in principal repayment and $3.0 million in prepayment premium, plus accrued and unpaid interest and expenses payable
through the payoff date.

ITEM 7A. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

We  are  exposed  to  various  market  risks  in  the  ordinary  course  of  our  business.  Market  risk  represents  the  risk  of  loss  that  may  impact  our
financial position due to adverse changes in financial market prices and rates. Our market risk exposure is primarily a result of fluctuations in
interest rates and foreign currency exchange rates. We do not hold or issue financial instruments for trading purposes. There were no material
quantitative changes in our market risk exposures between the year ended December 31, 2022 and the year ended December 31, 2021.

Interest rate sensitivity

Our exposure to market risk for changes in interest rates relates primarily to our investment portfolio. Our cash, cash equivalents and short-term
investment  accounts  as  of  December  31,  2022  totaled  $969.4  million  and  consist  of  cash,  cash  equivalents  and  short-term  investments  with
maturities of less than one year from the date of purchase. Our primary exposure to market risk is interest income sensitivity, which is affected
by  changes  in  the  general  level  of  the  interest  rates  in  the  United  States.  We  are  subject  to  interest  rate  fluctuation  exposure  through  our
investment in money market instruments which bear a variable interest rate. However, because of portfolio diversification, the short-term nature
of the instruments in our portfolio and our intent to hold non-money market instruments to maturity, a 10% change in market interest rates would
not be expected to have a material impact on our financial condition or our results of operations.

Foreign currency exchange risk

Our consolidated results of operations and cash flow are subject to fluctuations due to changes in foreign currency exchange rates. All of our
revenues are generated in the local currency for commercial markets. Our expenses are generally denominated in the currencies in which our
operations are located, which is primarily in the United States, Switzerland, Germany, Israel and Japan. Our consolidated results of operations
and cash flows are, therefore, subject to fluctuations due to changes in foreign currency exchange rates and may be adversely affected in the
future due to changes in foreign exchange rates. The effect of a hypothetical 10% change in foreign currency exchange rates applicable to our
business would not have a material impact on our historical consolidated financial statements. We do not hedge our foreign currency exchange
risk.

Report of Independent Registered Public Accounting Firm

To the Shareholders and the Board of Directors of NovoCure Limited

Opinion on the Financial Statements

We  have  audited  the  accompanying  consolidated  balance  sheets  of  NovoCure  Limited  and  subsidiaries  (the  Company)  as  of  December  31,
2022  and  2021,  the  related  consolidated  statements  of  operations,  comprehensive  income  (loss),  changes  in  shareholders’  equity  and  cash
flows for each of the three years in the period ended December 31, 2022 and the related notes (collectively referred to as the "consolidated
financial statements"). In our opinion, the consolidated financial statements present fairly, in all material respects, the financial position of the
Company at December 31, 2022 and 2021, and the results of its operations and its cash flows for each of the three years in the period ended
December 31, 2022, in conformity with U.S. generally accepted accounting principles.

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) ("PCAOB"), the
Company's  internal  control  over  financial  reporting  as  of  December  31,  2022,  based  on  criteria  established  in  Internal  Control-Integrated
Framework  issued  by  the  Committee  of  Sponsoring  Organizations  of  the  Treadway  Commission  (2013  framework)  and  our  report  dated
February 23, 2023 expressed an unqualified opinion thereon.

Basis for Opinion

These financial statements are the responsibility of the Company’s management. Our responsibility is to express an opinion on the Company’s
financial statements based on our audits. We are a public accounting firm registered with the 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 audit to obtain
reasonable  assurance  about  whether  the  financial  statements  are  free  of  material  misstatement,  whether  due  to  error  or  fraud.  Our  audits
included  performing  procedures  to  assess  the  risks  of  material  misstatement  of  the  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 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 financial statements. We believe that our audits provide a reasonable basis
for our opinion.

Critical Audit Matter

The  critical  audit  matter  communicated  below  is  a  matter  arising  from  the  current  period  audit  of  the  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 a 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.

65

Revenue recognition – Measuring variable consideration
Description of the Matter

As per the Company's consolidated statements of operations, the net revenues recognized during the fiscal year
of 2022 amounted to a sum of $538 million, which included variable consideration estimates. As described in Note
2 to the consolidated financial statements, the transaction price is determined based on the consideration to which
the Company will be entitled to in exchange for providing Optune solution. The company provides certain patients
with  implicit  price  concessions,  which  results  in  variable  consideration.  According  to  historical  records,  the
Company  expects  to  receive,  in  aggregate  for  a  given  portfolio,  less  than  the  gross  revenue  net  of  explicit
discounts. 

How We Addressed the
Matter in Our Audit

Auditing  the  Company's  measurement  of  variable  consideration  involved  challenging  judgment  because  the
calculation  involves  uncertainty  and  subjective  management  assumptions  about  estimates  of  expected  price
concessions. The implicit discount includes both an estimate of claims that will pay at an amount less than billed
and an estimate of claims that will not pay within a given time horizon. The implicit discount adjustments to the
transaction price are due to concessions, not collectability concerns driven by payer credit risk.

We  obtained  an  understanding,  evaluated  the  design  and  tested  the  operating  effectiveness  of  internal  controls
over  the  Company's  process  to  calculate  variable  consideration,  including  the  underlying  assumptions  about
estimates of expected price concessions.

Our  audit  procedures  included,  among  others,  evaluating  the  methodology  used,  analyzing  the  significant
assumptions  discussed  above,  and  testing  the  accuracy  and  completeness  of  the  underlying  data  used  in
management's calculation. This included testing inputs of the calculation by reconciliation of the data between the
various information systems performing independent recalculation of the Company's estimate and evaluating the
historical accuracy of management's estimates by comparing such estimates to subsequent actual results.

Report of Independent Registered Public Accounting Firm

To the Shareholders and the Board of Directors of NovoCure Limited

Opinion on Internal Control over Financial Reporting

We  have  audited  NovoCure  Limited  and  subsidiaries'  internal  control  over  financial  reporting  as  of  December  31,  2022,  based  on  criteria
established  in  Internal  Control–Integrated  Framework  issued  by  the  Committee  of  Sponsoring  Organizations  of  the  Treadway  Commission
(2013 framework) (the COSO Criteria). In our opinion, NovoCure Limited and subsidiaries (the Company) maintained, in all material respects,
effective internal control over financial reporting as of December 31, 2022, based on the COSO criteria.

We  also  have  audited,  in  accordance  with  the  standards  of  the  Public  Company  Accounting  Oversight  Board  (United  States)  (PCAOB),  the
consolidated  balance  sheets  of  the  Company  as  of  December  31,  2022  and  2021,  the  related  consolidated  statements  of  operations,
comprehensive income (loss) changes in shareholders’ equity and cash flows for each of the three years in the period ended December 31,
2022 and the related notes, and our report dated February 23, 2023 expressed an unqualified opinion thereon.

Basis for Opinion

The  Company’s  management  is  responsible  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. Our responsibility is to express an opinion on the Company’s internal control over financial reporting based on our audit.
We are a public accounting firm registered with the 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 audit in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether effective internal control over financial reporting was maintained in all material respects.

Our audit included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists,
testing  and  evaluating  the  design  and  operating  effectiveness  of  internal  control  based  on  the  assessed  risk,  and  performing  such  other
procedures as we considered necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinion.

Definition and Limitations of Internal Control Over Financial Reporting

A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial
reporting  and  the  preparation  of  financial  statements  for  external  purposes  in  accordance  with  generally  accepted  accounting  principles.  A
company’s internal control over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in
reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) provide reasonable assurance
that  transactions  are  recorded  as  necessary  to  permit  preparation  of  financial  statements  in  accordance  with  generally  accepted  accounting
principles,  and  that  receipts  and  expenditures  of  the  company  are  being  made  only  in  accordance  with  authorizations  of  management  and
directors of the company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or
disposition of the company’s assets that could have a material effect on the financial statements.

Because  of  its  inherent  limitations,  internal  control  over  financial  reporting  may  not  prevent  or  detect  misstatements.  Also,  projections  of  any
evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or
that the degree of compliance with the policies or procedures may deteriorate.

Note 1: Organization

NovoCure  Limited  (including  its  consolidated  subsidiaries,  the  "Company")  was  incorporated  in  the  Bailiwick  of  Jersey  and  is  principally
engaged in the development, manufacture and commercialization of Tumor Treating Fields ("TTFields") devices, including Optune and Optune
Lua (collectively, our "Products"), for the treatment of solid tumor cancers. The Company currently markets Optune in the United States ("U.S."),
Germany, Japan and certain other countries. The Company currently markets Optune Lua in the U.S. and European Union. The Company also
has a License and Collaboration Agreement (the "Zai Agreement") with Zai Lab (Shanghai) Co., Ltd. ("Zai") to market Optune in China, Hong
Kong, Macau and Taiwan ("Greater China"). See Note 12.

During the year ended December 31, 2019, the Company implemented changes to its corporate entity operating structure, including transferring
certain intellectual property to its Swiss subsidiary, primarily to align corporate entities with the Company’s evolving operations and business
model. As of January 1, 2022, the effective place of daily management and control of the Company moved to Switzerland and the Company
has become a Swiss tax resident.

Note 2: Basis of presentation and significant accounting policies

The  consolidated  financial  statements  are  prepared  in  accordance  with  accounting  principles  generally  accepted  in  the  United  States  (“U.S.
GAAP”).

a. Use of estimates:

The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the
amounts  reported  in  the  consolidated  financial  statements  and  accompanying  notes.  The  Company  evaluates  on  an  ongoing  basis  its
assumptions, including those related to contingencies, deferred taxes, tax liabilities, useful-life of field equipment, right-of-use assets and lease
liabilities, convertible notes, pension liabilities, revenue recognition, accrued expenses and share-based compensation costs. The Company’s
management believes that the estimates, judgment and assumptions used are reasonable based upon information available at the time they
are  made.  These  estimates,  judgments  and  assumptions  can  affect  the  reported  amounts  of  assets  and  liabilities  at  the  dates  of  the
consolidated  financial  statements,  and  the  reported  amounts  of  net  revenue  and  expenses  during  the  reporting  period.  Actual  results  could
differ from those estimates.

b. Financial statements in U.S. dollars:

The accompanying financial statements have been prepared in U.S. dollars in thousands, except for share and per-share data.

The Company finances its operations in U.S. dollars and a substantial portion of its costs and revenues from its primary markets is incurred in
U.S. dollars. As such, the Company’s management believes that the U.S. dollar is the currency of the primary economic environment in which
NovoCure Limited and certain subsidiaries operate. The Company’s reporting currency is U.S. dollars.

Transactions and balances denominated in U.S. dollars are presented at their original amounts. Monetary accounts maintained in currencies
other  than  the  U.S.  dollar  are  re-measured  into  dollars  in  accordance  with  Accounting  Standards  Codification  (ASC)  No.  830-10,  "Foreign
Currency Matters." All transaction gains and losses of the re-measurement of monetary balance sheet items are reflected in the consolidated
statements of operations as financial income or expenses, as applicable.

For  a  subsidiary  whose  functional  currency  has  been  determined  to  be  its  local  currency,  assets  and  liabilities  are  translated  at  year-end
exchange  rates  and  statement  of  operations  items  are  translated  at  average  exchange  rates  prevailing  during  the  year.  Such  translation
adjustments are recorded as a separate component of accumulated other comprehensive income (loss) in shareholders' equity.

c. Principles of consolidation:

The consolidated financial statements include the accounts of the Company and its wholly owned subsidiaries. Intercompany transactions and
balances, including unrealized profits from intercompany sales, have been eliminated upon consolidation.

d. Cash equivalents:

Cash equivalents are short-term, highly liquid investments that are readily convertible into cash with a maturity of three months or less at the
date acquired. 

e. Short-term investments:

The  Company  accounts  for  investments  in  debt  securities  in  accordance  with  ASC  320,  "Investments—Debt  and  Equity  Securities."
Management determines the appropriate classification of its investments in marketable debt securities at the time of purchase and reevaluates
such determinations at each balance sheet date. Investments in marketable debt securities can be classified as available-for-sale ("AFS") and
held-to-maturity ("HTM") when the Company has the intent and ability to hold the securities to maturity. As of December 31, 2022 and 2021, all
securities are classified as held-to-maturity since the Company has the intent and ability to hold the securities to maturity and, accordingly, debt
securities are stated at amortized cost.

Available-for-sale  debt  securities  are  carried  at  fair  value,  with  the  unrealized  gains  and  losses,  net  of  tax,  reported  in  accumulated  other
comprehensive income (loss) in shareholders’ equity. Realized gains and losses on sale of investments are included in financial income, net
and are derived using the specific identification method for determining the cost of securities sold.

The amortized cost of debt securities is adjusted for amortization of premiums and accretion of discounts to maturity. Such amortization together
with interest on securities is included in financial income, net.

Each reporting period, the Company evaluates whether declines in fair value below amortized cost are due to expected credit losses, as well as
the Company’s ability and intent to hold the investment until a forecasted recovery occurs. Allowance for credit losses on available-for-sale debt
securities are recognized in the Company’s consolidated statements of income, and any remaining unrealized losses, net of taxes, are included
in accumulated other comprehensive income (loss) in stockholders’ equity.

Held-to-maturity  debt  securities  are  stated  at  amortized  cost  of  which  is  adjusted  for  amortization  of  premiums  and  accretion  of  discounts  to
maturity and any credit losses. Such amortization, interest or credit losses are included in the consolidated statement of operations as financial
income or expenses, as appropriate.

For the years ended December 31, 2022, 2021 and 2020, no credit losses have been identified.

f. Restricted cash

The Company has restricted cash used as security for the use of Company credit cards and cash management, presented in short-term assets.
Additionally, the Company has pledged bank deposits to cover bank guarantees related to facility rental agreements, fleet lease agreements
and customs payments presented in other long-term assets (see Note 12).

g. Trade receivables:

The  Company’s  trade  receivables  balance  contains  billed  and  unbilled  commercial  activities.  The  Company  records  an  allowance  for  credit
losses,  if  identified.  The  Company  periodically  reviews  its  customers’  credit  risk  and  payment  history.  To  date,  the  Company  has  not
experienced any material credit losses related to counter-party risk.

h. Inventories:

Inventories  are  stated  at  the  lower  of  cost  or  net  realizable  value.  Cost  is  determined  using  the  weighted  average  method.  The  Company
regularly evaluates its ability to realize the value of inventory. If the inventories are deemed

76

Table of Contents

NovoCure Limited and subsidiaries
Notes to consolidated financial statements
U.S. dollars in thousands (except share and per share data)

damaged, if actual demand for the Company’s devices deteriorates, or if market conditions are less favorable than those projected, inventory
write-offs may be required.

Inventory write-offs of $917, $1,045 and $616, respectively, were recorded for the years ended December 31, 2022, 2021 and 2020.

i. Property and equipment:

Property and equipment are stated at cost, net of accumulated depreciation. Depreciation is calculated using the straight-line method over the
rates:

Over the shorter of the term of the lease or its useful life

Land and assets held within construction in progress are not depreciated. Construction in progress is related to the construction or development
of property and equipment that is not yet ready for its intended use.

j. Field equipment:

Field equipment is stated at cost, net of accumulated depreciation. Depreciation is calculated using the straight-line method over the estimated
useful  life  of  the  field  equipment,  which  was  determined  to  be  18  to  36  months.  Field  equipment  is  equipment  being  utilized  under  service
agreements, and accounted for in accordance with ASC 842 on a monthly basis as an operating lease (see Note 2(x)). The Company records a
write-off  provision  for  any  excess,  lost  or  damaged  equipment  when  warranted  based  on  an  assessment  of  the  equipment.  Write-offs  for
equipment are included in cost of revenues (see Note 7).

k. Impairment of long-lived assets:

The  Company’s  long-lived  assets  are  reviewed  for  impairment  in  accordance  with  ASC  360-10,  "Property,  Plant  and  Equipment,"  whenever
events or changes in circumstances indicate that the carrying amount of the asset may not be recoverable. Recoverability of an asset to be held
and used is measured by a comparison of the carrying amount of an asset to the future undiscounted cash flows expected to be generated by
the asset. If such asset is considered to be impaired, the impairment to be recognized is measured by the amount by which the carrying amount
of the asset exceeds its fair value. During the three years ended December 31, 2022, no impairment losses have been identified.

l. Other long-term assets:

Restricted  deposits,  long-term  lease  deposits  associated  with  office  rent  and  vehicles  under  operating  leases,  prepaid  and  vendors  down
payments are presented in other long-term assets.

m. Revenue recognition:

Our Products are comprised of two main components: (1) an electric field generator and (2) arrays and related accessories. We retain title to
the electric field generator, and the patient is provided replacement arrays and technical support for the device during the term of treatment. The
electric field generator and arrays are always supplied and function together and are not sold on a standalone basis.

The Company uses the portfolio approach to apply the standard to portfolios of contracts with similar characteristics.

To recognize revenue under ASC 606, the Company applies the following five steps:

1.
Identify the contract with a patient. A contract with a patient exists when (i) the Company enters into an enforceable contract
with  a  patient  that  defines  each  party’s  rights  regarding  delivery  of  and  payment  for  a  Product,  (ii)  the  contract  has  commercial
substance and (iii) the Company determines that collection of substantially all consideration for such Product is probable based on the
payer’s intent and ability to pay the promised consideration. The evidence of a contract generally consists of a prescription, a patient
service agreement and the verification of the assigned payer for the contract and intention to collect.

77

 
Table of Contents

NovoCure Limited and subsidiaries
Notes to consolidated financial statements
U.S. dollars in thousands (except share and per share data)

2.
Identify  the  performance  obligations  in  the  contract.  Our  contracts  include  the  lease  of  the  device,  the  supply  obligation  of
disposable arrays and technical support for the term of treatment. To the extent a contract includes multiple promised products and/or
services, the Company must apply judgment to determine whether those products and/or services are capable of being distinct in the
context  of  the  contract.  If  these  criteria  are  not  met  the  promised  products  and/or  services  are  accounted  for  as  a  combined
performance  obligation.  In  the  Company’s  case,  the  device,  support,  and  disposables  are  provided  as  one  inseparable  package  of
monthly treatment for a single monthly fee. For more information, see Note 2(x).

3.
Determine the transaction price. The transaction price is determined based on the consideration to which the Company will be
entitled  in  exchange  for  providing  a  Product  to  the  patient.  To  the  extent  the  transaction  price  includes  variable  consideration,  the
Company estimates the amount of variable consideration that should be included in the transaction price utilizing either the expected
value  method  or  the  most  likely  amount  method  depending  on  the  nature  of  the  variable  consideration.  Variable  consideration  is
included  in  the  transaction  price  if,  in  the  Company’s  judgment,  it  is  probable  that  a  significant  future  reversal  of  cumulative  revenue
under  the  contract  will  not  occur.  The  Company  has  agreements  with  many  payers  that  define  explicit  discounts  off  the  gross
transaction price. In addition to the explicit discounts negotiated with each payer, the Company expects to receive, in aggregate for a
given  portfolio,  less  than  the  gross  revenue  net  of  explicit  discounts.  ASC  606  requires  that  the  Company  recognize  this  variable
consideration as an implicit discount in the billing period. The implicit discount includes both an estimate of claims that will pay at an
amount less than billed and an estimate of claims that will not pay within a given time horizon. The implicit discount adjustments to the
transaction price are due to concessions, not collectability concerns driven by payer credit risk.

Allocate the transaction price to performance obligations in the contract. If a contract contains a single performance obligation,
4.
the  entire  transaction  price  is  allocated  to  the  single  performance  obligation.  As  discussed  above,  there  is  a  combined  performance
obligation under the Company’s contracts and, therefore, the monthly transaction price determined for the performance obligation will
be recognized over time ratably over the monthly term of the treatment.

Recognize  revenue  when  or  as  the  Company  satisfies  a  performance  obligation.  The  Company  satisfies  performance
5.
obligations  over  time.  Revenue  is  recognized  at  the  time  the  related  performance  obligation  is  satisfied  by  transferring  a  promised
service to a patient. The patient consumes the benefits of treatment on a daily basis over the monthly term. As this criterion is met, the
revenues will be recognized over the monthly term. For more information, see Note 2(x).

Revenues are presented net of indirect taxes.

Net  revenues  in  the  years  ended  December  31,  2022,  2021  and  2020  also  include  amounts  recognized  pursuant  to  the  Zai  Agreement.  For
additional information, see Note 12.

n. Charitable care:

The Company provides treatment at no charge to patients who meet certain criteria under its charitable care policy. Because the Company does
not  pursue  collection  of  amounts  determined  to  qualify  as  charity,  they  are  not  reported  as  revenue.  The  Company's  costs  of  care  provided
under charitable care were $3,009, $4,204 and $3,653 for the years ended December 31, 2022, 2021 and 2020, respectively. These amounts
were determined by applying charitable care as a percentage of gross billings to total cost of goods sold.

o. Shipping and handling costs:

The Company does not separately bill its customers for shipping and handling costs associated with shipping Products to its customers. These
direct  shipping  and  handling  costs  of  $3,211,  $2,958  and  $3,224  for  the  years  ended  December  31,  2022,  2021  and  2020,  respectively,  are
included in Sales and Marketing costs.

p. Accounting for share-based compensation:

The Company accounts for share-based compensation in accordance with ASC 718, "Compensation—Stock Compensation." ASC 718 requires
companies to estimate the fair value of share-based compensation awards on the date of grant using an option-pricing model. The value of the
award is recognized as an expense over the

78

Table of Contents

NovoCure Limited and subsidiaries
Notes to consolidated financial statements
U.S. dollars in thousands (except share and per share data)

requisite service periods in the Company’s consolidated statements of operations. The Company's policy is to account for forfeitures as they
occur.

The Company recognizes compensation costs for the value of awards granted using the accelerated method over the requisite service period of
the award, which for restricted share units is two or three years and and for option awards, which is two or four years.

The Company recognizes compensation costs for the value of performance stock units ("PSU") over the performance period when the vesting
conditions become probable in accordance with ASC 718.

The  Company  applies  the  Black-Scholes  model  as  it  believes  it  is  the  most  appropriate  fair  value  method  for  all  equity  awards  and  for  the
Employee Share Purchase Plan (the "ESPP"). For market condition awards, the Company also applies the Monte-Carlo simulation model. The
Black-Scholes model requires a number of assumptions, of which the most significant are the share price, expected volatility and the expected
award term.

Beginning  with  the  first  quarter  of  2022,  the  computation  of  expected  volatility  is  based  on  the  historical  volatility  the  Company's  shares,
beginning with the first quarter of 2021 and prior to the first quarter of 2022, the computation of expected volatility is based on a combination of
actual historical share price volatility of comparable publicly-traded companies and the historical volatility the Company's shares. Prior to the
first quarter of 2021, due to the lack of sufficient historical information for the Company, the computation was based on actual historical volatility
of comparable publicly-traded companies. Beginning with the first quarter of 2021, the expected term of options granted is calculated using the
Company's historical and future exercise behavior. Prior to the first quarter of 2021, it was calculated using the average between the vesting
period  and  the  contractual  term  to  the  expected  term  of  the  options  in  effect  at  the  time  of  grant.  The  Company  has  historically  not  paid
dividends and has no foreseeable plans to pay dividends and, therefore, uses an expected dividend yield of zero in the option pricing model.
The risk-free interest rate is based on the yield of U.S. treasury bonds with equivalent terms.

q. Fair value of financial instruments:

The  carrying  amounts  of  cash  and  cash  equivalents,  short-term  investments,  restricted  cash,  receivables  and  prepaid  expenses,  trade
receivables, trade payables and other accounts payable and accrued expenses approximate their fair value due to the short-term maturity of
such instruments.

The Company accounts for certain assets and liabilities at fair value under ASC 820, "Fair Value Measurements and Disclosures." Fair value is
an exit price, representing the amount that would be received to sell an asset or paid to transfer a liability in an orderly transaction between
market  participants.  As  such,  fair  value  is  a  market-based  measurement  that  should  be  determined  based  on  assumptions  that  market
participants would use in pricing an asset or a liability.

The  hierarchy  below  lists  three  levels  of  fair  value  based  on  the  extent  to  which  inputs  used  in  measuring  fair  value  are  observable  in  the
market.  The  Company  categorizes  each  of  its  fair  value  measurements  in  one  of  these  three  levels  based  on  the  lowest  level  input  that  is
significant to the fair value measurement in its entirety.

The three levels of inputs that may be used to measure fair value are as follows:

Level 1 - Observable inputs that reflect quoted prices (unadjusted) for identical assets or liabilities in active markets;

Level 2 - Includes other inputs that are directly or indirectly observable in the marketplace, other than quoted prices included in Level 1, such as
quoted prices for similar assets or liabilities in active markets, quoted prices for identical or similar assets or liabilities in markets with insufficient
volume or infrequent transactions, or other inputs that are observable (model-derived valuations in which significant inputs are observable), or
can be derived principally from or corroborated by observable market data; and

Level 3 - Unobservable inputs which are supported by little or no market activity.

The availability of observable inputs can vary from instrument to instrument and is affected by a wide variety of factors, including, for example,
the type of instrument, the liquidity of markets and other characteristics particular to the transaction. To the extent that valuation is based on
models  or  inputs  that  are  less  observable  or  unobservable  in  the  market,  the  determination  of  fair  value  requires  more  judgment  and  the
instrument is categorized as Level 3.

Notes to consolidated financial statements
U.S. dollars in thousands (except share and per share data)

r. Basic and diluted net loss per share:

Basic  net  income  (loss)  per  share  is  computed  based  on  the  weighted  average  number  of  ordinary  shares  outstanding  during  each  period.
Diluted  net  income  per  share  is  computed  based  on  the  weighted  average  number  of  ordinary  shares  outstanding  during  the  period,  plus
potential  dilutive  shares  considered  outstanding  during  the  period,  in  accordance  with  ASC  260-10,  as  determined  under  the  treasury  stock
method.

s. Income taxes:

The  Company  accounts  for  income  taxes  in  accordance  with  ASC  740-10,  "Income  Taxes."  ASC  740-10  prescribes  the  use  of  the  liability
method whereby deferred tax asset and liability account balances are determined based on differences between the financial reporting and tax
bases of assets and liabilities and are measured using the enacted tax rates and laws that will be in effect when the differences are expected to
reverse. The Company provides a valuation allowance, to reduce deferred tax assets to their estimated realizable value, if needed.

The Company established reserves for uncertain tax positions based on the evaluation of whether or not the Company’s uncertain tax position
is "more likely than not" to be sustained upon examination. The Company records interest and penalties pertaining to its uncertain tax positions
in the financial statements as income tax expense.

t. Concentration of risks:

Our  cash,  cash  equivalents,  short-term  investments  and  trade  receivables  are  potentially  subject  to  a  concentration  of  risk.  Cash,  cash
equivalents and short-term investments are invested at top tier financial institutions globally. As such, these investments may be in excess of
insured  limitations  or  not  insured  in  certain  jurisdictions.  Generally,  these  investments  may  be  redeemed  upon  demand  and  therefore,  bear
minimal risk.

Our  trade  receivables  are  due  from  numerous  governments  and  federal  and  state  agencies  that  are  paid  from  their  respective  budgets,  and
from  hundreds  of  health  insurance  companies.  The  Company  does  not  believe  that  there  are  significant  default  risks  associated  with  these
governments, agencies and health insurance companies based upon the Company's historical experience with them.

The  Company  has  no  off-balance  sheet  concentrations  of  credit  risk  such  as  foreign  exchange  contracts,  option  contracts  or  other  foreign
hedging arrangements.

u. Retirement, pension and severance plans:

The  Company  has  a  401(k)  retirement  savings  plan  for  its  U.S.  employees.  Each  eligible  employee  may  elect  to  contribute  a  portion  of  the
employee’s  compensation  to  the  plan.  Company  contributions  to  the  plan  are  at  the  sole  discretion  of  the  Company's  Board  of  Directors.
Currently, the Company provides a matching contribution of 50% of the employee's contributions, up to a maximum of three percent (3%) of the
employee's annual salary. The Company began making matching contributions as of January 1, 2019. For the years ended December 31, 2022,
2021 and 2020, the Company had made matching contributions in the amount of $2,083 and $1,967 and $1,589, respectively, pursuant to the
plan.

The Company sponsors a defined benefit plan (the "Swiss Plan") for all its employees in Switzerland for retirement benefits, as well as benefits
on death or long-term disability, whereby the employee and the Company contribute a portion of the employee's compensation to the plan. The
Swiss  Plan  is  part  of  a  collective  pension  foundation  “AXA  Foundation  for  Occupational  Benefits”.  This  is  a  semi-autonomous  pension
foundation, meaning that the underlying investment risk and the longevity are born by the pension foundation itself. Disability and death risks
are reinsured with AXA insurance. Notwithstanding, the Company and its employees bear the risk of having to pay recovery contributions in a
financial distress situation. The Company accounts for this risk in accordance with ASC 715, "Compensation – Retirement Benefits" (see Note
9). The pension expense for the years ended December 31, 2022, 2021 and 2020 was $2,104, $1,494 and $1,588, respectively.

Israeli  law  generally  requires  payment  of  severance  pay  upon  dismissal  of  an  employee  or  upon  termination  of  employment  in  certain  other
circumstances.  The  Company  contributes  to  employee  pension  plans  to  fund  its  severance  liabilities.  According  to  Section  14  of  Israel
Severance Pay Law, the Company makes deposits on behalf of its employees with respect to the Company’s severance liability and therefore
no obligation is provided for in the financial statements. Severance pay liabilities with respect to employees who are not subject to Section 14,
are provided for in the financial statements based upon the number of years of service and the latest monthly salary and

80

the  related  deposits  are  recorded  as  an  asset  based  on  the  cash  surrender  value.  Contributions  pursuant  to  these  obligations  for  the  years
ended December 31, 2022, 2021 and 2020 amounted to $1,594, $1,466 and $1,130, respectively.

v. Contingent liabilities:

The  Company  accounts  for  its  contingent  liabilities  in  accordance  with  ASC  450,  "Contingencies."  A  provision  is  recorded  when  it  is  both
probable that a liability has been incurred and the amount of the loss can be reasonably estimated.

With respect to legal matters, provisions are reviewed and adjusted to reflect the impact of negotiations, estimated settlements, legal rulings,
advice of legal counsel and other information and events pertaining to a particular matter.

w. Other comprehensive income (loss):

The  Company  accounts  for  comprehensive  income  (loss)  in  accordance  with  ASC  220,  "Comprehensive  Income."  ASC  220  establishes
standards for the reporting and display of comprehensive income (loss) and its components. Comprehensive income (loss) generally represents
all  changes  in  shareholders'  equity  during  the  period  except  those  resulting  from  investments  by,  or  distributions  to,  shareholders.  The
accumulated  other  comprehensive  income  (loss),  net  of  taxes,  relates  to  a  pension  liability,  unrealized  loss  from  debt  securities  and  foreign
currency translation adjustments.

x. Leases:

1.

Lessee accounting:

The  Company  determines  if  an  arrangement  is  a  lease  and  the  classification  of  that  lease  at  inception  based  on:  (1)  whether  the  contract
involves the use of a distinct identified asset, (2) whether the Company obtains the right to substantially all the economic benefits from the use
of  the  asset  throughout  the  period,  and  (3)  whether  the  Company  has  a  right  to  direct  the  use  of  the  asset.  The  Company  elected  to  not
recognize a lease liability or right-of-use ("ROU") asset for leases with a term of twelve months or less. The Company also elected the practical
expedient to not separate lease and non-lease components for its leases.

ROU  assets  represent  the  right  to  use  an  underlying  asset  for  the  lease  term  and  lease  liabilities  represent  the  obligation  to  make  minimum
lease payments arising from the lease. ROU assets are initially measured at amounts, which represents the discounted present value of the
lease payments over the lease, plus any initial direct costs incurred. The ROU assets are reviewed for impairment. The lease liability is initially
measured at lease commencement date based on the discounted present value of minimum lease payments over the lease term. The implicit
rate within the operating leases are generally not determinable; therefore, the Company uses the Incremental Borrowing Rate ("IBR") based on
the  information  available  at  commencement  date  in  determining  the  present  value  of  lease  payments.  The  Company’s  IBR  is  estimated  to
approximate the interest rate on similar terms and payments and in economic environments where the leased asset is located.

Certain leases include options to extend or terminate the lease. An option to extend the lease is considered in connection with determining the
ROU  asset  and  lease  liability  when  it  is  reasonably  certain  that  the  Company  will  exercise  that  option.  An  option  to  terminate  is  considered
unless it is reasonably certain that the Company will not exercise the option.

2.    Lessor accounting - Operating leases:

ASC 842 provides lessors with an optional practical expedient, by class of underlying asset, not to separate non-lease components from the
associated  lease  component  and,  instead,  to  account  for  those  components  as  a  single  component  if  the  non-lease  components  otherwise
would be accounted for under the new revenue guidance (ASC 606) and both of the following criteria are met:

a. The timing and pattern of transfer of the lease component and the non-lease component(s) are the same; and

b. The lease component would be classified as an operating lease if it were accounted for separately.

The Company's product supply agreements include the right to use the device (lease component), the supply obligation of disposable arrays
and technical support for the term of treatment (non-lease component).

81

Table of Contents

Notes to consolidated financial statements
U.S. dollars in thousands (except share and per share data)

If  the  lease  component  is  the  predominant  component,  the  Company  accounts  for  all  revenues  under  such  lease  as  a  single  component  in
accordance with the new lease accounting standard. Conversely, if the non-lease component is the predominant component, all revenues under
such lease are accounted for in accordance with the revenue recognition accounting standard. The Company's operating leases qualify for the
single  component  accounting,  and  the  non-lease  component  in  each  of  the  Company's  leases  is  predominant.  Therefore,  The  Company
accounts for all revenues from its operating leases in accordance with the revenue recognition accounting standard.

y. Convertible note:

Prior to January 1, 2021, the Company accounted for its convertible senior notes in accordance with ASC 470-20 "Debt with Conversion and
Other Options". Pursuant to ASC Subtopic 470-20, issuers of certain convertible debt instruments, such as the convertible senior notes, that
have a net settlement feature and may be settled wholly or partially in cash upon conversion are required to separately account for the liability
(debt) and equity (conversion option) components of the instrument. The Company allocated the proceeds from issuance between the liability
component and the embedded conversion option, or equity component. The liability component at issuance is recognized at fair value, based
on the fair value of a similar instrument of similar credit rating and maturity that does not have a conversion feature. The equity component is
based  on  the  excess  of  the  principal  amount  of  the  convertible  senior  notes  over  the  fair  value  of  the  liability  component  and  is  recorded  in
additional paid-in capital. The equity component, net of issuance costs is presented within additional paid-in-capital and is not remeasured as
long as it continues to meet the conditions for equity classification. The Company allocated the total issuance costs incurred to the liability and
equity components of the convertible senior notes based on the same proportions as the proceeds from the notes.

In August 2020, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") No. 2020-06, Accounting for
Convertible  Instruments  and  Contracts  in  an  Entity’s  Own  Equity  (ASU  2020-06),  which  simplifies  the  accounting  for  certain  financial
instruments with characteristics of liabilities and equity, including convertible instruments and contracts in an entity’s own equity. Among other
changes,  ASU  2020-06  removes  from  GAAP  the  liability  and  equity  separation  model  for  convertible  instruments  with  a  cash  conversion
feature,  and  as  a  result,  after  adoption,  entities  will  no  longer  separately  present  in  equity  an  embedded  conversion  feature  for  such  debt.
Similarly, the embedded conversion feature will no longer be amortized into income as interest expense over the life of the instrument. Instead,
entities will account for a convertible debt instrument wholly as debt unless (1) a convertible instrument contains features that require bifurcation
as a derivative under Accounting Standards Codification ("ASC Topic 815"), Derivatives and Hedging, or (2) a convertible debt instrument was
issued  at  a  substantial  premium.  Additionally,  ASU  2020-06  requires  the  application  of  the  if-converted  method  to  calculate  the  impact  of
convertible instruments on diluted earnings per share (EPS), which is consistent with the Company’s accounting treatment under the current
standard. ASU 2020-06 is effective for fiscal years beginning after December 15, 2021, with early adoption permitted for fiscal years beginning
after December 15, 2020, and can be adopted on either a fully retrospective or modified retrospective basis. The Company early adopted ASU
2020-06, effective January 1, 2021 on a modified retrospective basis.

Commencing January 1, 2021, the Company early adopted ASU 2020-06. The impact of the Company’s adoption of ASU 2020-06 on the
balance sheet as of January 1, 2021 was an increase in long term debt, net of $128,972, a decrease in additional paid-in capital of $132,474,
and a decrease in accumulated deficit of $3,502. Interest expense recognized in future periods will be reduced as a result of accounting for the
convertible debt instrument as a single liability measured at its amortized cost. For additional information see Note 10 of these audited
consolidated financial statements.

Note 3: Cash and Cash equivalents and Short-term investments

Cash  equivalents  include  items  almost  as  liquid  as  cash  with  maturity  periods  of  three  months  or  less  when  purchased,  and  short-term
investments include items with maturity dates between three months and one year when purchased. As of December 31, 2022 and 2021, the
Company’s cash and cash equivalents and short-term investments were composed of:

(1)  Changes  in  fair  value  of  HTM  securities  are  presented  for  disclosure  purposes  as  required  by  ASC  320  and  are  recorded  as  finance
expenses only if the unrealized loss is identified as a credit loss.

In November 2022, the Company transferred all of its AFS portfolio to HTM as part of the Company's investment strategy. Such transfers are
made at fair value at the date of transfer, The net unrealized loss on these securities at the date of transfer was $911. These securities continue
to be reported in accumulated comprehensive income (loss) and are amortized over the remaining lives of the securities as an adjustment to
the yield. As of December 31, 2022, the unamortized unrealized loss balance was $445 and is reported in accumulated other comprehensive
income (loss).

In accordance with ASC No. 820, the Company measures its money market funds and marketable securities at fair value. Money market funds
and marketable securities are classified within Level 1 or Level 2. This is because these

83

assets are valued using quoted market prices or alternative pricing sources and models utilizing market observable inputs.

As of December 31, 2022 and 2021, all investments and equivalents mature in one year or less.

Unrealized  losses  from  debt  securities  are  primarily  attributable  to  changes  in  interest  rates.  The  Company  does  not  believe  any  remaining
unrealized losses represent impairments based on the evaluation of available evidence.

Debt securities with continuous unrealized losses for less than 12 months and their related fair values were as follows:

Note 9: Employee benefit obligations

The Company's liability in respect of the Swiss Plan (see Note 2(u)) is the projected benefit obligation calculated using the projected unit credit
method.  The  projected  benefit  obligation  as  of  December  31,  2022  represents  the  actuarial  present  value  of  the  estimated  future  payments
required to settle the obligation that is attributable to employee service rendered before that date. Swiss Plan assets are recorded at fair value.
Pension expense is presented in the payroll expenses in the various functions in which the employees are engaged. Actuarial gains and losses
arising  from  differences  between  the  actual  and  the  expected  return  on  the  Swiss  Plan  assets  are  recognized  in  accumulated  other
comprehensive  income  (loss)  and  amortized  over  the  requisite  service  period.  The  Swiss  Plan  is  part  of  a  collective  pension  foundation  of
pooled  investments  managed  by  a  top  tier  insurance  company.  The  Company  and  the  employees  pay  retirement  contributions,  which  are
defined as a percentage of the employees’ covered salaries.The basis for the determination of the interest on employee’s savings account is
the return on plan assets, considering legal minimum requirements. The targeted allocation for these funds is as follows:

On November 5, 2020, the Company issued $575,000 aggregate principal amount of 0% Convertible Senior Notes due 2025 (the “Notes”). The
net proceeds from the offering were approximately $558,400.

The Notes are senior unsecured obligations of the Company. The Notes do not bear regular interest, and the principal amount of the Notes will
not accrete. Special interest, if any, payable in accordance with the terms of the Notes will be payable in cash semi-annually in arrears on May 1
and November 1 of each year, beginning on May 1, 2021. The Notes mature on November 1, 2025, unless earlier repurchased, redeemed or
converted.

The  Notes  are  convertible  into  cash,  the  Company’s  ordinary  shares  or  a  combination  of  cash  and  the  Company’s  ordinary  shares  at  the
Company’s election at an initial conversion rate of 5.9439 ordinary shares per $1,000 principal amount of the Notes, which is equivalent to an
initial conversion price of approximately $168.24 per ordinary share.

In  January  2021,  the  Company  irrevocably  elected  to  settle  all  conversions  of  Notes  by  a  combination  of  cash  and  the  Company's  ordinary
shares  and  that  the  cash  portion  per  $1,000  principal  amount  of  Notes  for  all  conversion  settlements  shall  be  $1,000.  Accordingly,  from  and
after the date of the election, upon conversion of any Notes,

88

 
 
 
 
 
Table of Contents

NovoCure Limited and subsidiaries
Notes to consolidated financial statements
U.S. dollars in thousands (except share and per share data)

holders of Notes will receive, with respect to each $1,000 principal amount of Notes converted, cash in an amount up to $1,000 and the balance
of the conversion value, if any, in ordinary shares (the "Conversion Shares").

The Notes are not redeemable prior to November 6, 2023, except in the event of certain tax law changes. The Company may redeem for cash
all or any portion of the Notes, at the Company’s option, on or after November 6, 2023 if the last reported sale price of the Company’s ordinary
shares has been at least 130% of the conversion price then in effect for at least 20 trading days (whether or not consecutive) during any 30
consecutive trading day period (including the last trading day of such period) ending on, and including, the trading day immediately preceding
the date on which the Company provides notice of redemption at a redemption price equal to 100% of the principal amount of the Notes to be
redeemed, plus accrued and unpaid special interest, if any, to, but excluding, the redemption date. No sinking fund is provided for the Notes.

Prior to the close of business on the business day immediately preceding August 1, 2025, the Notes are convertible at the option of the holders
only upon the satisfaction of certain conditions and during certain periods as described below and if the Company exercises its right to redeem
the  Notes  as  permitted  or  required  by  the  Indenture  as  described  below.  On  or  after  August  1,  2025  until  the  close  of  the  business  on  the
business day immediately preceding the maturity date, holders may convert all or any portion of their Notes at the conversion rate at any time
irrespective of the foregoing conditions.

If holders of at least $3,000 aggregate principal amount of the Notes provide the Company with reasonable evidence that the trading price per
$1,000 principal amount of Notes (the “Note Trading Price”) on any trading day would be less than 98% of the product of the last reported sale
price of the Ordinary Shares on such trading day and the conversion rate on such trading day (the “Trigger Note Price”), the Company shall
follow the process for obtaining the Note Trading Price as provided in the Indenture on a daily basis until the Note Trading Price exceeds the
Trigger Notice Price. During this time, if during any five consecutive trading day period (the “Measurement Period”) the Note Trading Price is
less than 98% of the Trigger Notice Price, the Company must notify the holders and the trustee of such an event and the holders may convert
their Notes into Ordinary Shares at any time during the five business day period immediately after.

If  the  Company  intends  to  (i)  issue  warrants/rights/options  to  existing  shareholders  with  an  exercise  price  less  than  the  ten-day  trailing  last
trading price average or (ii) distribute to shareholders assets, securities or rights with a value per share greater than 10% of the last reported
trading price, then the Company must give holders of the Notes thirty-five (35) trading days’ notice of such event, at which time a holder may
convert their Notes during such 35 trading day period (or until the Company revokes its decision to issue/distribute the securities, whichever
comes sooner).

In addition, upon the occurrence of a fundamental change (as defined in the indenture), holders may require the Company to repurchase for
cash  all  or  any  portion  of  their  Notes  at  a  fundamental  change  repurchase  price  equal  to  100%  of  the  principal  amount  of  the  Notes  to  be
repurchased, plus accrued and unpaid special interest, if any, to, but excluding, the fundamental change repurchase date. In addition, following
certain corporate events that occur prior to the maturity date or if the Company delivers a notice of redemption, the Company will, in certain
circumstances, increase the conversion rate for a holder who elects to convert its Notes in connection with such a corporate event or notice of
redemption, as the case may be.

As of December 31, 2022, the conditions allowing holders of the Notes to convert were not met. The Notes are therefore not convertible as of
December 31, 2022 and are classified as long-term liability.

The  net  carrying  amount  of  the  liability  and  equity  components  of  the  Convertible  Notes  (see  note  2(z)  for  additional  information)  as  of
December 31, 2022 and 2021 are as follows:

On February 7, 2018, the Company and certain of its subsidiaries entered into a Loan and Security Agreement ("2018 Loan Agreement") with
BioPharma Credit PLC pursuant to which such lender made a term loan to the Company in the principal amount of $150,000 (the "2018 Credit
Facility").  The  term  loan,  which  was  drawn  in  full  upon  execution  of  the  2018  Loan  Agreement,  bore  interest  at  9.0%  per  annum,  payable
quarterly in arrears.

On August 18, 2020, the Company terminated the 2018 Credit Facility. The prepayment included $150,000 in principal repayment and $3,000 in
prepayment premium, plus accrued and unpaid interest and expenses payable through the payoff date. The un-amortized issuance costs in the
amount of $478 that were fully amortized upon the repayment and the prepayment premium were reported in the Company’s finance expenses.

The facilities of the Company are leased under various operating lease agreements for periods ending no later than 2044. The Company also
has  the  option  to  extend  the  term  of  certain  facility  lease  agreements  and  these  are  included  in  the  calculation  of  right-of-use  assets.  The
Company also leases motor vehicles under various operating leases, which expire on various dates, the latest of which is in 2025.

Under ASC 842, all leases with durations greater than 12 months, including non-cancelable operating leases, are recognized on the balance
sheet. The aggregated present value of lease payments is recorded as a long-term asset titled right-of-use assets. The corresponding lease
liabilities are split between other payables and long-term lease liabilities, and as of December 31, 2022, are as follows:

b.    Bank guarantee and pledges

As  of  December  31,  2022  and  2021  the  Company  pledged  bank  deposits  of  $2,296  and  $2,350,  respectively,  to  cover  bank  guarantees  in
respect  of  its  leases  of  operating  facilities  and  obtained  guarantees  by  the  bank  for  the  fulfillment  of  the  Company’s  lease  commitments  of
$2,459 and $2,698, respectively.

c.     Senior secured revolving credit facility

On  November  6,  2020,  the  Company  entered  into  a  new  three-year  $150,000  senior  secured  revolving  credit  facility  with  a  syndicate  of
relationship  banks  (the  "Credit  Facility").  The  Company  may,  subject  to  certain  conditions  and  limitations,  increase  the  revolving  credit
commitments outstanding under the revolving credit facility or incur new incremental term loans in aggregate principal amount not to exceed
$250.0 million in total.

The  commitments  under  the  Credit  Facility  are  guaranteed  by  certain  of  the  Company's  subsidiaries  and  secured  by  a  first  lien  on  the
Company's and certain of the Company's subsidiaries’ assets. Outstanding loans will bear interest per annum at a sliding scale based on the
Company's secured leverage ratio from 2.75% to 3.25% above the applicable interbank borrowing reference rate for the currency in which the
loan  is  denominated.  Additionally,  the  facility  contains  a  fee  for  the  unused  revolving  credit  commitments  at  a  sliding  scale  based  on  the
Company's secured leverage ratio from 0.35% to 0.45%. The Credit Facility contains financial covenants requiring maintenance of a minimum
fixed charge coverage ratio and specifying a maximum senior secured net leverage ratio, as well as customary events of default which include a
change of control.

As of December 31, 2022, the Company had no outstanding balance borrowed under the Credit Facility.

On February 17, 2023, the Company gave irrevocable notice to the administrative agent under the Credit Facility that the Company terminated
all  commitments,  effective  February  22,  2023.  This  effectively  terminated  the  Credit  Facility,  as  the  Company's  ability  to  borrow  and  the
Company's obligations to comply with all covenants ended on such date. The liens and guaranties in favor of the lenders are released. There
was no early termination fee payable and as of February 22, 2023 the Company had no outstanding balance borrowed under the Credit Facility.

d.     Zai License and Collaboration Agreement

On September 10, 2018, the Company entered into the Zai Agreement. Under the Zai Agreement, the Company granted Zai exclusive rights to
commercialize Optune in the field of oncology in China, Hong Kong, Macau and

91

Table of Contents

NovoCure Limited and subsidiaries
Notes to consolidated financial statements
U.S. dollars in thousands (except share and per share data)

Taiwan  ("Greater  China").  The  Zai  Agreement  also  established  a  development  partnership  for  Optune  in  multiple  solid  tumor  indications.  In
partial consideration for the license grant to Zai for Greater China, the Company was entitled to a non-refundable, up-front license fee in the
amount  of  $15,000  (the  "License  Fee").  The  Zai  Agreement  also  provides  for  certain  development,  regulatory  and  commercial  milestone
payments totaling up to $78,000. Furthermore, pursuant to the Zai Agreement, Zai will pay the Company tiered royalties at percentage rates
from 10 up to the mid-teens on the net sales of the licensed products in Greater China. Zai is purchasing licensed products for commercial use
exclusively from the Company at the Company’s fully burdened manufacturing cost.

The  Company  recognizes  revenue  pursuant  to  the  License  Agreement  with  Zai  in  accordance  with  ASC  606,  "Revenue  Recognition  from
Customers."  The  License  Fee  is  deferred  and  recognized  over  related  six  year  performance  period  commencing  September  10,  2018  ("Zai
Performance Period"). Revenue from commercial milestone payments will be recognized upon the achievement of such milestones and future
clinical or regulatory milestone payments will be recognized in a straight line over the applicable performance period, in accordance with ASC
606. Revenue from royalty payments are recognized in accordance with ASC 606 in the period accrued. Revenues from sales of product or
rendering services are recognized upon shipping the products or rendering the services and satisfying the performance obligation.

During the year ended December 31, 2020, the Company triggered an aggregate $10,000 of milestone payments, which, with the License Fee,
are deferred and recognized over the remainder of the Zai Performance Period ending in September 2024 on a straight-line basis, resulting in
revenue of $4,389 $6,308 and $3,981 for the years ended December 31, 2022, 2021 and 2020, respectively.

b.     Theoretical tax
The Company's effective tax rate is affected by the tax rates in the various jurisdictions in which the Company operates. Under Swiss law, the
Company is subject to income tax at the federal level at a statutory rate of 8.5%, as well as at the cantonal and communal levels, resulting in an
aggregate corporate tax rate of 12.0%.

For purposes of comparability, the Company used the Swiss federal statutory rate for the 2022, 2021 and 2020 tax years when presenting the
Company's reconciliation of the income tax provision.

Until the IPO in October 2015, the Company maintained and granted option awards under the 2003 Share Option Plan (the "2003 Plan") and
the 2013 Equity Incentive Share Option Plan (the "2013 Plan") for the Company’s officers, directors, employees and advisors. The 2003 Plan
and the 2013 Plan terminated as of the IPO as to future awards, but they continue to govern option awards previously granted thereunder.

In  September  2015,  the  Company  adopted  the  2015  Omnibus  Incentive  Plan  (the  "2015  Plan").  The  Company’s  shareholders  approved  the
2015 Plan in September 2015. Under the 2015 Plan, the Company can issue various types of equity compensation awards such as restricted
shares, performance shares, restricted stock units ("RSUs"), performance share units ("PSUs"), long-term cash award and other share-based
awards. Options granted under the 2015 Plan generally have a vesting period of two or four years and expire ten years after the date of grant.
RSUs granted under the 2015 Plan vest in equal installments over two or three years. PSUs granted under the 2015 Plan generally vest have a
vesting period between three and six years, as performance targets are attained. Options, RSUs and PSUs granted under the 2015 Plan that
are canceled before expiration become available for future grants. 

On  December  31,  2022,  in  accordance  with  the  terms  of  the  2015  Plan,  the  number  of  shares  available  for  issuance  under  the  2015  Plan
automatically  increased  by  4%  of  the  Company’s  outstanding  ordinary  shares  as  of  December  30,  2022. As  a  result,  the  number  of  shares
available  for  issuance  under  the  2015  Plan  increased  from  39,264,853  shares  to  43,465,227  shares.  As  of  December  31,  2022,20,630,323
ordinary shares are available for grant under the 2015 Plan.

Employee Stock Purchase Plan

In  September  2015,  the  Company  adopted  an  ESPP  to  encourage  and  enable  eligible  employees  to  acquire  ownership  of  the  Company’s
ordinary shares purchased through accumulated payroll deductions on an after-tax

95

 
 
 
Table of Contents

Notes to consolidated financial statements
U.S. dollars in thousands (except share and per share data)

basis. The ESPP is intended to be an "employee stock purchase plan" within the meaning of Section 423 of the Code and the provisions of the
ESPP will be construed in a manner consistent with the requirements of such section. The Company began its offerings under the ESPP on
August 1, 2016. The Company issued 86,264 ordinary shares for the plan period from January 1, 2022 through December 31, 2022.

The  terms  of  the  ESPP  provide  that  on  December  31  of  each  year,  the  number  of  shares  available  for  purchase  by  eligible  employees  who
participate  in  the  ESPP  automatically  increases  by  1%  of  the  Company’s  outstanding  ordinary  shares  outstanding,  unless  the  Company
determines that such an increase is not necessary. The Company determined that an such increase was not necessary and no such increase
took place. As of December 31, 2022, 4,868,733 ordinary shares are available for offering under the ESPP.

The fair value of share-based awards was estimated using the Black-Scholes model for all equity grants and for market condition awards. The
Company also applied the Monte-Carlo simulation model, with the following underlying assumptions:

In certain markets and for certain key components, the Company is currently dependent upon sole source suppliers used in its devices. The
Company’s  management  believes  that  in  most  cases  other  suppliers  could  provide  similar  components  at  comparable  terms.  A  change  of
suppliers which requires FDA or other regulatory approval, however, could cause a material delay in manufacturing and a possible loss of sales,
which could adversely affect the Company’s operating results and financial position.

ITEM 9. CHANGES IN AND DISAGREEMENTS WITH ACCOUNTANTS ON ACCOUNTING AND FINANCIAL DISCLOSURE

None.

ITEM 9A. CONTROLS AND PROCEDURES

(a) Evaluation of Disclosure Controls and Procedures

Our management, with the participation of our Chief Executive Officer and Chief Financial Officer, evaluated the effectiveness of our disclosure
controls and procedures as of the end of the period covered by this Annual Report on Form 10-K. Based on that evaluation, the Chief Executive
Officer and Chief Financial Officer concluded that our disclosure controls and procedures as of the end of the period covered by this Annual
Report on Form 10-K have been designed and are functioning effectively to provide reasonable assurance that the information required to be
disclosed by us in reports filed under the Securities Exchange Act of 1934 is recorded, processed, summarized and reported within the time
periods specified in the SEC’s rules and forms. We believe that a controls system, no matter how well designed and operated, cannot provide
absolute assurance that the objectives of the controls system are met, and no evaluation of controls can provide absolute assurance that all
control issues and instances of fraud, if any, within a company have been detected.

(b) Management’s Annual Report on Internal Control over Financial Reporting

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  to  provide  reasonable  assurance
regarding  the  reliability  of  financial  reporting  and  the  preparation  of  financial  statements  for  external  purposes  in  accordance  with  general
accepted  accounting  principles.  Because  of  its  inherent  limitations,  internal  control  over  financial  reporting  may  not  prevent  or  detect
misstatements.  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.

Our  management  assessed  the  effectiveness  of  our  internal  control  over  financial  reporting  as  of  December  31,  2022.  In  making  this
assessment,  it  used  the  criteria  established  in  Internal  Control-  Integrated  Framework  (2013)  issued  by  the  Committee  of  Sponsoring
Organizations of the Treadway Commission (COSO). Based on such assessment, management has concluded that, as of December 31, 2022,
our internal control over financial reporting is effective based on those criteria.

(c) Attestation Report of the Registered Public Accounting Firm

The effectiveness of our internal control over financial reporting as of December 31, 2022, has been audited by Kost Forer Gabbay & Kasierer,
a  member  of  Ernst  &  Young  Global,  an  independent  registered  public  accounting  firm,  as  stated  in  their  attestation  report,  which  is  included
herein.

(d) Changes in Internal Control over Financial Reporting

There have been no changes in our internal control over financial reporting during our most recent fiscal quarter that have materially affected, or
are reasonably likely to materially affect, our internal control over financial reporting.

ITEM 9B. OTHER INFORMATION

On  February  22,  2023,  the  Board  of  Directors  (the  “Board”)  of  the  Company  elected  Allyson  J.  Ocean,  M.D.,  effective  immediately,  to  fill  an
existing vacancy on the Board. Dr. Ocean will receive compensation for her service on the Board as a non-employee member of the Board in
the  same  manner  as  other  non-employee  members  of  the  Board.  For  a  description  of  the  Company’s  director  compensation  programs,  see

Table of Contents

oncology  at  NewYork-Presbyterian  Hospital/Weill  Cornell  Medical  Center,  as  well  as  a  medical  oncologist  at  The  Jay  Monahan  Center  for
Gastrointestinal Health. Dr. Ocean is co-founder and Scientific Advisory Board Chair of Let’s Win Pancreatic Cancer, an award-winning non-
profit  organization  missioned  to  increase  access  to  treatment  options  and  clinical  trials  for  patients  with  pancreatic  cancer.  Additionally,  Dr.
Ocean serves on several scientific advisory boards. Dr. Ocean graduated cum laude from Tufts University and received her M.D. with honors
from the Tufts University School of Medicine.

Dr. Ocean will be appointed to a Board committee at a later date.

Upon her election to the Board, and pursuant to the Company’s Non-Employee Director Plan, Dr. Ocean will be awarded an option under the
Company's  2015  Omnibus  Incentive  Plan  as  of  February  28,  2023  ("Grant  Date")  to  purchase  ordinary  shares  of  the  Company  with  an
aggregate Grant Date fair value of $667,000 (subject to rounding of shares to the nearest whole number) using the Black-Scholes pricing model
and the valuation assumptions used by the Company in accounting for options as of the Grant Date at an exercise price per share equal to the
closing price of the Company’s ordinary shares on the Grant Date (the “Options”). The Options shall vest in equal amounts on the first, second
and third anniversary of the Grant Date.

There is no arrangement or understanding between Dr. Ocean and any other persons pursuant to which Dr. Ocean was elected to serve on the
Board.

Dr. Ocean does not have any direct or indirect material interest in any transaction or proposed transaction required to be reported under Item
404(a) of Regulation S-K or Item 5.02(d) of Form 8-K.

Termination of a Material Definitive Agreement.

On February 17, 2023, the Company gave irrevocable notice under the Company’s Credit Agreement, dated as of November 6, 2020, by and
among the Company, as borrower, JPMorgan Chase Bank, N.A., as administrative agent and the financial institutions party thereto, (“Lenders”)
(as  amended,  restated,  supplemented  or  otherwise  modified,  the  “Credit  Agreement”)  to  terminate  all  commitments,  effective  February  22,
2023. This effectively terminated the Credit Facility, as the Company’s ability to borrow and its obligations to comply with all covenants ended on
such  date.  The  liens  and  guaranties  in  favor  of  the  Lenders  are  released.  As  of  the  date  of  termination,  the  Company  had  no  outstanding
balance borrowed under the Credit Agreement. No early termination fees or penalties were payable in connection with the termination.

NOVOCURE LIMITED
DESCRIPTION OF SECURITIES REGISTERED PURSUANT TO
SECTION 12 OF THE SECURITIES EXCHANGE ACT OF 1934

Exhibit 4.1

NovoCure  Limited,  a  Jersey  corporation  (“we,”  “us”  or  “our”)  has  one  class  of  securities  registered  pursuant  to  Section  12  of  the
Securities Exchange Act of 1934:  our ordinary shares, no par value per share. Our ordinary shares are listed on the NASDAQ Global Select
Market under the symbol “NVCR.”

The general terms and provisions of our ordinary shares are summarized below. This summary does not purport to be complete and is
qualified in all respects by reference to certain provisions of the Companies (Jersey) Law 1991 (the “Jersey Companies Law”) and our amended
and restated articles of association (our “articles of association”) and our memorandum of association, which have been filed as an exhibit to
our most recent Annual Report on Form 10-K filed with the Securities and Exchange Commission (the “SEC”) and are hereby incorporated by
reference. Our articles of association and our memorandum of association may be amended from time to time, with any such amendments to
be reflected by a document filed with one of our periodic or current reports filed with the SEC subsequent to the date of such Annual Report. 

Our authorized share capital consists of an unlimited number of no par value shares, comprised of (i) an unlimited number of ordinary
shares,  and  (ii)  an  unlimited  number  of  preferred  shares,  of  which  no  preferred  shares  are  currently  outstanding.  Our  articles  of  association
provide  that  preferred  shares  may  be  issued  from  time  to  time  in  one  or  more  classes.  Our  board  of  directors  is  authorized  to  fix  the  voting
rights, if any, designations, powers, preferences, the relative participating, optional or other special rights, and any qualifications, limitations and
restrictions thereof, applicable to the shares of each class. Our board of directors is able, without shareholder approval, to issue any authorized
but unissued preferred shares with voting and other rights that could adversely affect the voting power and other rights of the holders of the
ordinary shares. The ability of our board of directors to issue preferred shares without shareholder approval could have the effect of delaying,
deferring or preventing a change of control of us or the removal of existing management.

Description of Ordinary Shares

General

Voting rights

Holders of our ordinary shares are entitled to one vote per share on matters to be voted on by shareholders. The Jersey Companies

Law does not confer any pre-emptive rights to purchase our shares from our shareholders. There is no cumulative voting of shares.

Dividends and other distributions

Holders of our ordinary shares are entitled to receive such dividends, if any, as may be approved by our board of directors in its
discretion. In order to be able to declare any dividends, our directors must make a statutory solvency statement to the effect that we will be able
to discharge our liabilities as they fall due and that, having regard to our prospects as to the intention of the directors with respect to the
management of our business, and with the amount and character of the financial resources that will in the view of the directors be available to
us, we will be able to continue to carry on business and discharge our liabilities as they fall due for a 12-month period immediately following the
date on which the dividend is proposed to be paid (or until we are dissolved on a solvent basis, if earlier). Dividends must be apportioned and
paid pro rata according to the amounts paid on shares, unless otherwise specified in the

 
rights attached to a specific class or classes of shares. Dividends do not accrue interest and may, if unclaimed, be invested by our board of
directors on our behalf until claimed. Any dividend unclaimed after a period of seven years from the date of declaration of such dividend or the
date on which such dividend became due for payment is forfeited and becomes our property.

Our articles of association provide that our board of directors may offer our shareholders the right to receive in lieu of any cash dividend
(or part thereof) that we declare on our ordinary shares, such number of our ordinary shares that are (or nearly as possible) equivalent in value
to the cash dividend, based on the market price of such shares determined in accordance with our articles of association.

Winding up

If we are wound up (whether the liquidation is voluntary, under supervision or by the courts of Jersey), the liquidator (or the board of
directors, where no liquidator is appointed) may, with the authority of a special resolution of our shareholders, divide among our shareholders
part or all of our assets, or transfer any part of our assets to a trustee for the benefit of our shareholders.

Changes in capital and allotment of securities

We may, by special resolution of our shareholders, alter our memorandum of association to change the amount of our share capital,
consolidate all or any of our shares (whether issued or not) into fewer shares or divide all or any of our shares (whether issued or not) into more
shares,  cancel  any  unissued  shares  or  alter  our  share  capital  in  any  other  way  permitted  by  the  Jersey  Companies  Law.  Subject  to  the
provisions of the Jersey Companies Law, our board of directors has the discretion to issue authorized but unissued shares.

Variation of class rights

The rights attaching to any class of shares may only be altered by approval of holders of not less than two-thirds (2/3) of the number of
the issued shares of that class, or by special resolution of the relevant class passed at a class shareholder meeting by the holders of not less
than two-thirds (2/3) in number of the issued shares of such class, in each case, being voted in person or by proxy at such meeting. In addition,
unless otherwise expressly provided by the conditions of issue of, or statement of rights relating to, any shares or class of shares, the rights
conferred upon the holders of any shares or class of shares (regardless of whether they are issued with preferred, deferred or other special
rights) will not be deemed to be varied or abrogated by the creation or issue of further shares or classes of shares (including additional shares
of such class), the conversion and redemption of shares in accordance with our articles of association or any applicable statement of rights, or
the purchase or redemption by us of our own shares.

Special meetings

Under the Jersey Companies Law, only our board of directors or shareholders holding at least 10% of the total voting rights of our share
capital can requisition a shareholders’ meeting. A meeting requisitioned by shareholders must be held within two months of receipt by us of the
written request, but such shareholders may call the meeting if our board of directors does not call the meeting within 21 days of the date of
deposit of the written request at our registered office, in which event such meeting must be held within three months of the date of deposit of the
written  request  of  our  registered  office.  Our  articles  of  association  specifies  the  information  that  a  shareholder  requisitioning  a  shareholders’
meeting is required to provide with its written request for the requisition of a shareholders’ meeting.

Actions by written consent

Our Articles of Association permits the adoption of an ordinary or special resolution of shareholders by written consent; however, Jersey
law  and  our  Articles  of  Association  require  that  any  ordinary  or  special  resolution  adopted  by  written  consent  be  signed  by  all  shareholders
entitled to vote on such resolution.

Shareholders may adopt an ordinary or special resolution in writing, if all of the following conditions are met:

1. All shareholders entitled to vote receive:

a. a copy of the ordinary or special resolution; and
b. a statement informing shareholders how to signify their agreement to the resolution (which may be by electronic

means) and the date by which the resolution must be passed if it is not to lapse twenty-eight days after the circulation
date; and

2.All shareholders entitled to vote:

a.    sign a document; or
b.    sign several documents in the like form each signed by one or more of the shareholders entitled to vote; and
c.    the signed document is returned to us at the place and time indicated in the notice (which may be by electronic

means).

The notice to shareholders must be in addition to (if not already included in) any notice or proxy statement required to be distributed in
accordance with U.S. securities law or exchange regulation applicable to the class of shares being voted. Each shareholder has one vote for
each eligible share held by such shareholder, and, unless specified otherwise in the document transmitting the shareholder's approval of the
resolution, all such eligible shares will be voted for such resolution.

Directors

Our  board  of  directors  may  vary  the  minimum  or  maximum  number  of  directors  (subject  to  a  minimum  of  two  and  a  maximum  of  13
directors), and may appoint directors to fill any vacancies. In 2018, our articles of association were amended to declassify the board of directors.
In  2020,  our  Class  I  and  Class  II  directors  will  be  elected  to  one-year  terms  expiring  at  our  annual  meeting  of  shareholders  in  2021  and,
beginning with our annual meeting of shareholders in 2021, all directors will be elected to one-year terms expiring at the subsequent annual
meeting of shareholders.

Shareholders are only able to appoint a person as a director at a shareholder meeting if (i) the relevant person has been recommended
by  our  board  of  directors  or  is  a  serving  director  who  is  retiring  at  that  shareholder  meeting;  or  (ii)  if  a  shareholder  (other  than  the  person
proposed as a director) who is entitled to attend and vote at that shareholder meeting has submitted written notice to us of their intention to
nominate the relevant person no less than 90 and no more than 120 full days prior to the date of that shareholder meeting, along with a notice
from the relevant person confirming their willingness to be appointed.
