Summary Risk Factors

our business is subject to numerous risks and uncertainties that could affect our ability to successfully implement our
business  strategy  and  affect  our  financial  results.  You  should  carefully  consider  all  of  the  information  in  this  report  and,  in
particular, the following principal risks and all of the other specific factors described in item 1a. of this report, “risk Factors,”
before deciding whether to invest in our company.

● We  depend  heavily  on  JaKaFi/JaKavi  (ruxolitinib),  and  if  we  are  not  able  to  maintain  revenues  from

JaKaFi/JaKavi or those revenues decrease, our business may be materially harmed.

●

if we or our collaborators are unable to obtain, or maintain at anticipated levels, reimbursement for JaKaFi/JaKavi or
our other products from government and other third-party payors, our results of operations and financial condition could
be harmed.

● a limited number of specialty pharmacies and wholesalers represent a significant portion of revenues from JaKaFi, and
the  loss  of,  or  significant  reduction  in  sales  to,  any  one  of  these  specialty  pharmacies  or  wholesalers  could  harm  our
operations and financial condition.

●

●

●

●

if  we  are  unable  to  establish  and  maintain  effective  sales,  marketing  and  distribution  capabilities,  or  to  enter  into
agreements with third parties to do so, we will not be able to successfully commercialize our products.

if  we  fail  to  comply  with  applicable  laws  and  regulations,  we  could  lose  our  approval  to  market  our  products  or  be
subject to other governmental enforcement activity.

if the use of our products harms or is perceived to harm patients, our regulatory approvals could be revoked or otherwise
negatively impacted or we could be subject to costly product liability claims.

if we market our products in a manner that violates various laws and regulations, we may be subject to civil or criminal
penalties.

● Competition for our products, in particular JaKaFi/JaKavi, could harm our business and result in a decrease in our

revenue.

●

the CoviD-19 pandemic and measures to address the pandemic have adversely affected and can in the future adversely
affect our business and results of operations.

● We  or  our  collaborators  may  be  unsuccessful  in  discovering  and  developing  drug  candidates,  and  we  may  spend

significant time and money attempting to do so, in particular with our later stage drug candidates.

●

if  we  or  our  collaborators  are  unable  to  obtain  regulatory  approval  in  and  outside  of  the  united  States  for  drug
candidates, we and our collaborators will be unable to commercialize those drug candidates.

● health  care  reform  measures  could  impact  the  pricing  and  profitability  of  pharmaceuticals,  and  adversely  affect  the

commercial viability of our or our collaborators’ products and drug candidates.

● Conflicts  between  us  and  our  collaborators  or  termination  of  our  collaboration  agreements  could  limit  future

development and commercialization of our drug candidates and harm our business.

●

●

●

if we are unable to establish collaborations to fully exploit our drug discovery and development capabilities or if future
collaborations are unsuccessful, our future revenue prospects could be diminished.

if we fail to enter into additional in-licensing agreements or if these arrangements are unsuccessful, we may be unable to
increase our number of successfully marketed products and our revenues.

Even if one of our drug candidates receives regulatory approval, we may determine that commercialization would not be
worth the investment.

● any  approved  drug  product  that  we  bring  to  the  market  may  not  gain  market  acceptance  by  physicians,  patients,

healthcare payors and others in the medical community.

5

table of Contents

● We have limited capacity to conduct preclinical testing and clinical trials, and our resulting dependence on other parties

could result in delays in and additional costs for our drug development efforts.

● We face significant competition for our drug discovery and development efforts, and if we do not compete effectively,

our commercial opportunities will be reduced or eliminated.

● our  reliance  on  others  to  manufacture  our  drug  products  and  drug  candidates  could  result  in  drug  supply  constraints,

delays in clinical trials, increased costs, and withdrawal or denial of regulatory approvals.

●

●

if we fail to comply with the extensive legal and regulatory requirements  affecting the health care industry, we could
face increased costs, penalties and a loss of business.

the illegal distribution and sale by third parties of counterfeit or unfit versions of our or our collaborators’ products or
stolen products could harm our business and reputation.

● as most of our drug discovery and development operations are conducted at our headquarters in Wilmington, Delaware,

the loss of access to this facility would negatively impact our business.

●

if we lose any of our key employees or are unable to attract and retain additional personnel, our business and ability to
achieve our objectives could be harmed.

●

if we fail to manage our growth effectively, our ability to develop and commercialize products could suffer.

● We  may  acquire  businesses  or  assets,  form  joint  ventures  or  make  investments  in  other  companies  that  may  be

unsuccessful, divert our management’s attention and harm our operating results and prospects.

● risks associated with our operations outside of the united States could adversely affect our business.

●

if  product  liability  lawsuits  are  brought  against  us,  we  could  face  substantial  liabilities  and  may  be  required  to  limit
commercialization of our products, and our results of operations could be harmed.

● Because our activities involve the use of hazardous materials, we may be subject to claims relating to improper handling,

storage or disposal of these materials that could be time consuming and costly.

● We expect to continue to incur significant expenses to discover and develop drugs, which could result in future losses

and impair our achievement of and ability to sustain profitability in the future.

●

if we are unable to raise additional capital in the future when we require it, our efforts to broaden our product portfolio
or commercialization efforts could be limited.

● our marketable securities and long term investments are subject to risks that could adversely affect our overall financial

position.

●

if we are unable to achieve milestones, develop product candidates to license or renew or enter into new collaborations,
our royalty and milestone revenues and future prospects for those revenues may decrease.

● any  arbitration  or  litigation  involving  us  and  regarding  intellectual  property  infringement  claims  could  be  costly  and

disrupt our drug discovery and development efforts.

● our inability  to adequately  protect  or enforce  our proprietary  information  may  result  in loss  of revenues  or otherwise

reduce our ability to compete.

●

●

●

●

if the effective term of our patents is decreased or if we need to refile some of our patent applications, the value of our
patent portfolio and the revenues we derive from it may be decreased.

international patent protection is particularly uncertain and costly, and our involvement in opposition proceedings may
result in the expenditure of substantial sums and management resources.

Significant  disruptions  of  information  technology  systems,  breaches  of  data  security,  or  unauthorized  disclosures  of
sensitive data could harm our business and subject us to liability or reputational damage.

increasing use of social media could give rise to liability, breaches of data security, or reputational damage, which could
harm our business and results of operations.

Item 1.  Business

Overview

incyte  is  a  biopharmaceutical  company  focused  on  the  discovery,  development  and  commercialization  of  proprietary
therapeutics.  our  global  headquarters  is  located  in  Wilmington,  Delaware,  where  we  conduct  global  commercial  and  clinical
development  operations.  We  also  conduct  commercial  and  clinical  development  operations  from  our  European  headquarters  in
morges, Switzerland and clinical development operations from our Japanese office in tokyo.

as described in more detail below, our business is composed of three franchises that are defined by the indications of

our approved medicines and the diseases for which our clinical candidates are being developed.

Hematology and Oncology

our  hematology  and  oncology  franchise  is  comprised  of  four  approved  products,  which  are  JaKaFi  (ruxolitinib),
monJuvi (tafasitamab-cxix), pEmaZYrE (pemigatinib) and iCluSiG (ponatinib), as well as numerous clinical development
programs.

JAKAFI (ruxolitinib)

JaKaFi (ruxolitinib) is our first product to be approved for sale in the united States. it was approved by the u.S. Food
and Drug administration (FDa) in november 2011 for the treatment of adults with intermediate or high-risk myelofibrosis (mF),
in  December  2014  for  the  treatment  of  adults  with  polycythemia  vera  (pv)  who  have  had  an  inadequate  response  to  or  are
intolerant of hydroxyurea and in may 2019 for the treatment of steroid-refractory acute graft-versus-host disease (GvhD) in adult
and pediatric patients 12 years and older. myelofibrosis and polycythemia vera are both myeloproliferative neoplasms (mpns), a
type of rare blood cancer, and GvhD is an adverse immune response to an allogeneic hematopoietic stem cell transplant (hSCt).
under our collaboration agreement with our collaboration partner novartis pharmaceutical international ltd., novartis received
exclusive development and commercialization rights to ruxolitinib outside of the united States for all hematologic and oncologic
indications and sells ruxolitinib outside of the united States under the name JaKavi.

 in 2003, we initiated a research and development program to explore the inhibition of enzymes called janus associated
kinases (JaK). the JaK family is composed of four tyrosine kinases—JaK1, JaK2, JaK3 and tyk2—that are involved in the
signaling  of  a  number  of  cytokines  and  growth  factors.  JaKs  are  central  to  a  number  of  biologic  processes,  including  the
formation  and  development  of  blood  cells  and  the  regulation  of  immune  functions.  Dysregulation  of  the  JaK-Stat  signaling
pathway  has  been  associated  with  a  number  of  diseases,  including  myeloproliferative  neoplasms,  other  hematological
malignancies, rheumatoid arthritis and other chronic inflammatory diseases.

We  have  discovered  multiple  potent,  selective  and  orally  bioavailable  JaK  inhibitors  that  are  selective  for  JaK1  or

JaK1 and JaK2. JaKaFi is the most advanced compound in our JaK program. it is an oral JaK1 and JaK2 inhibitor.

JaKaFi is marketed in the united States through our own specialty sales force and commercial team. JaKaFi was the
first  FDa-approved  JaK  inhibitor  for  any  indication  and  was  the  first  FDa-approved  product  in  all  three  of  its  current
indications.  JaKaFi  remains  the  first-line  standard  of  care  in  mF  and  remains  the  only  FDa-approved  product  for  pv  and
steroid-refractory acute GvhD. the FDa has granted JaKaFi orphan drug status for mF, pv, Et, acute lymphoblastic leukemia
(all) and GvhD.

to help ensure that all eligible patients have access to JaKaFi, we have established a patient assistance program called
incyteCarES (CarES stands for Connecting to access, reimbursement,  Education and Support). incyteCarES helps ensure
that  any  patient  with  intermediate  or  high-risk  mF,  uncontrolled  pv  or  steroid-refractory  acute  GvhD  who  meets  certain
eligibility  criteria  and  is  prescribed  JaKaFi  has  access  to  the  product  regardless  of  ability  to  pay  and  has  access  to  ongoing
support and educational resources during treatment.

table of Contents

JaKaFi  is  distributed  primarily  through  a  network  of  specialty  pharmacy  providers  and  wholesalers  that  allow  for
efficient  delivery  of  the  medication  by  mail  directly  to  patients  or  direct  delivery  to  the  patient’s  pharmacy.  our  distribution
process uses a model that is well-established and familiar to physicians who practice within the oncology field.

to  further  support  appropriate  use  and  future  development  of  JaKaFi,  our  u.S.  medical  affairs  department  is
responsible  for  providing  appropriate  scientific  and  medical  education  and  information  to  physicians,  preparing  scientific
presentations and publications, and overseeing the process for supporting investigator sponsored trials.

Myelofibrosis.   myelofibrosis  is  a  rare,  life-threatening  condition.  mF,  considered  the  most  serious  of  the

myeloproliferative neoplasms, can occur either as primary mF, or as secondary mF that develops in some patients who previously
had polycythemia vera or essential thrombocythemia. We estimate there are between 16,000 and 18,500 patients with mF in the
united  States.  Based  on  the  modern  prognostic  scoring  systems  referred  to  as  international  prognostic  Scoring  System  and
Dynamic international prognostic Scoring System, we believe intermediate and high-risk patients represent 80%  to 90%  of all
patients with mF in the united States and encompass patients over the age of 65, or patients who have or have ever had any of the
following:  anemia,  constitutional  symptoms,  elevated  white  blood  cell  or  blast  counts,  or  platelet  counts  less  than  100,000  per
microliter of blood.

most mF patients have enlarged spleens and many suffer from debilitating symptoms, including abdominal discomfort,
pruritus (itching), night sweats and cachexia (involuntary weight loss). there were no FDa approved therapies for mF until the
approval of JaKaFi.

the FDa approval was based on results from two randomized phase iii trials (ComFort-i and ComFort-ii), which
demonstrated  that  patients  treated  with  JaKaFi  experienced  significant  reductions  in  splenomegaly  (enlarged  spleen).
ComFort-i  also  demonstrated  improvements  in  symptoms.  the  most  common  hematologic  adverse  reactions  in  both  trials
were  thrombocytopenia  and  anemia.  these  events  rarely  led  to  discontinuation  of  JaKaFi  treatment.  the  most  common  non-
hematologic adverse reactions were bruising, dizziness and headache.

in august 2014, the FDa approved supplemental labeling for JaKaFi to include Kaplan-meier overall survival curves
as  well  as  additional  safety  and  dosing  information.  the  overall  survival  information  is  based  on  three-year  data  from
ComFort-i and ii, and shows that at three years the probability of survival for patients treated with JaKaFi in ComFort-i
was 70% and for those patients originally randomized to placebo it was 61%. in ComFort-ii, at three years the probability of
survival for patients treated with JaKaFi was 79% and for patients originally randomized to best available therapy it was 59%.
 in December 2016, we announced an exploratory pooled analysis of data from the five-year follow-up of the ComFort-i and
ComFort-ii trials of patients treated with JaKaFi, which further supported previously published overall survival findings.

in September 2016, we announced that JaKaFi had been included as a recommended treatment in the latest national
Comprehensive Cancer network (nCCn) Clinical practice Guidelines in oncology for myelofibrosis, underscoring the important
and long-term clinical benefits seen in patients treated with JaKaFi.

in  october  2017,  the  FDa  approved  updated  labeling  for  JaKaFi  to  include  the  addition  of  new  patient-reported
outcome  (pro)  data  from  the  ComFort-i  study,  as  well  as  updating  the  warning  related  to  progressive  multifocal
leukoencephalopathy.  an  exploratory  analysis  of  pro  data  of  patients  with  myelofibrosis  receiving  JaKaFi  showed
improvement  in  fatigue-related  symptoms  at  Week  24.  Fatigue  response  (defined  as  a  reduction  of  4.5  points  or  more  from
baseline in the promiS® Fatigue total score) was reported in 35% of patients treated with JaKaFi versus 14% of the patients
treated with placebo.

Polycythemia Vera.   pv  is  a  myeloproliferative  neoplasm  typically  characterized  by  elevated  hematocrit,  the  volume
percentage of red blood cells in whole blood, which can lead to a thickening of the blood and an increased risk of blood clots, as
well  as  an  elevated  white  blood  cell  and  platelet  count.  When  phlebotomy  can  no  longer  control  pv,  chemotherapy  such  as
hydroxyurea, or interferon, is utilized. approximately 25,000 patients with pv in the united States are considered uncontrolled
because they have an inadequate response to or are intolerant of hydroxyurea, the most commonly used chemotherapeutic agent
for the treatment of pv.

in  December  2014,  the  FDa  approved  JaKaFi  for  the  treatment  of  patients  with  pv  who  have  had  an  inadequate
response  to  or  are  intolerant  of  hydroxyurea.  the  approval  of  JaKaFi  for  pv  was  based  on  data  from  the  pivotal  phase  iii
rESponSE trial. in this trial, patients treated with JaKaFi demonstrated superior hematocrit control and reductions in spleen
volume compared to best available therapy. in addition, a greater proportion of patients treated with JaKaFi achieved complete
hematologic remission—which was defined as achieving hematocrit control, and lowering platelet and white blood cell counts. in
the rESponSE trial, the most common hematologic adverse reactions (incidence > 20%) were thrombocytopenia and anemia.
the  most  common  non-hematologic  adverse  events  (incidence  >10%)  were  headache,  abdominal  pain,  diarrhea,  dizziness,
fatigue, pruritus, dyspnea and muscle spasms.

in  march  2016,  the  FDa  approved  supplemental  labeling  for  JaKaFi  to  include  additional  safety  data  as  well  as
efficacy analyses from the rESponSE trial to assess the durability of response in JaKaFi treated patients after 80 weeks. at this
time, 83% patients were still on treatment, and 76% of the responders at 32 weeks maintained their response through 80 weeks.

in  June  2016,  we  announced  data  from  the  phase  iii  rESponSE-2  study  of  JaKaFi  in  patients  with  inadequately
controlled  pv  that  was  resistant  to  or  intolerant  of  hydroxyurea  who  did  not  have  an  enlarged  spleen.  these  data  showed  that
JaKaFi  was  superior  to  best  available  therapy  in  maintaining  hematocrit  control  (62.2%  vs.  18.7%,  respectively;  p<0.0001)
without the need for phlebotomy.

in  august  2017,  we  announced  that  JaKaFi  had  been  included  as  a  recommended  treatment  in  the  latest  nCCn
Guidelines for patients with polycythemia vera who have had an inadequate response to first-line therapies, such as hydroxyurea.

Graft-versus-host disease. GvhD  is  a  condition  that  can  occur  after  an  allogeneic  hSCt  (the  transfer  of  genetically
dissimilar stem cells or tissue). in GvhD, the donated bone marrow or peripheral blood stem cells view the recipient’s body as
foreign and attack  various tissues. 12-month survival rates in  patients with Grade iii  or iv  steroid-refractory acute GvhD are
50%  or  less,  and  the  incidence  of  steroid-refractory  acute  and  chronic  GvhD  is  approximately  3,000  per  year  in  the  united
States.

in  June  2016,  we  announced  that  the  FDa  granted  Breakthrough  therapy  designation  for  ruxolitinib  in  patients  with
acute GvhD. in may 2019, the FDa approved JaKaFi for the treatment of steroid-refractory acute GvhD in adult and pediatric
patients  12  years  and  older.  the  approval  was  based  on  data  from  rEaCh1,  an  open-label,  single-arm,  multicenter  study  of
JaKaFi in combination with corticosteroids in patients with steroid-refractory grade ii-iv acute GvhD. the overall response
rate  (orr)  in  patients  refractory  to  steroids  alone  was  57%  with  a  complete  response  (Cr)  rate  of  31%.  the  most  frequently
reported  adverse  reactions  among  all  study  participants  were  infections  (55%)  and  edema  (51%),  and  the  most  common
laboratory abnormalities were anemia (75%), thrombocytopenia (75%) and neutropenia (58%).

We  have  retained  all  development  and  commercialization  rights  to  JaKaFi  in  the  united  States  and  are  eligible  to
receive development and sales milestones as well as royalties from product sales outside the united States. We hold patents that
cover the composition of matter and use of ruxolitinib, which patents, including applicable extensions, expire in late 2027.

MONJUVI (tafasitamab-cxix)

in  January  2020,  we  and  morphoSys  aG  entered  into  a  collaboration  and  license  agreement  to  further  develop  and
commercialize  morphoSys'  proprietary  anti-CD19  antibody  tafasitamab  (mor208)  globally.  the  agreement  became  effective
march 2020. tafasitamab is an Fc-engineered antibody against CD19 currently in clinical development for the treatment of B cell
malignancies.  We  have  rights  to  co-commercialize  tafasitamab  in  the  united  States  with  morphoSys,  and  we  have  exclusive
development and commercialization rights outside of the united States.

in July 2020, we and morphoSys announced that the FDa approved monJuvi (tafasitamab-cxix), which is indicated in
combination  with  lenalidomide  for  the  treatment  of  adult  patients  with  relapsed  or  refractory  diffuse  large  B-cell  lymphoma
(DlBCl) not otherwise specified, including DlBCl arising from low grade lymphoma, and who are not

9

table of Contents

eligible  for  autologous  stem  cell  transplant  (aSCt).  monJuvi  was  approved  under  accelerated  approval  based  on  overall
response rate.

in august 2020, we and morphoSys announced that monJuvi in combination with lenalidomide had been included in

the latest national Comprehensive Cancer network (nCCn) Clinical practice Guidelines in oncology for B-cell lymphomas.

DlBCl  is  the  most  common  type  of  non-hodgkin  lymphoma  in  adults  worldwide,  comprising  40%  of  all  cases.
DlBCl is characterized by rapidly growing masses of malignant B-cells in the lymph nodes, spleen, liver, bone marrow or other
organs. it is an aggressive disease with ~40% of patients not responding to initial therapy or relapsing thereafter. We estimate that
there are ~10.000 patients diagnosed in the united States each year with relapsed or refractory diffuse large B-cell lymphoma (r/r
DlBCl) who are not eligible for aSCt.

the approval of monJuvi was based on data from the morphoSys-sponsored phase ii l-minD study, an open label,
multicenter, single arm trial of monJuvi in combination with lenalidomide as a treatment for adult patients with r/r DlBCl.
results from the study showed an objective response rate (orr) of 55% (39 out of 71 patients; primary endpoint) and a complete
response (Cr) rate of 37% (26 out of 71 patients). the median duration of response (mDor) was 21.7 months. the most frequent
serious adverse reactions were infections (26%), including pneumonia (7%) and febrile neutropenia (6%).

PEMAZYRE (pemigatinib)

in  april  2020,  we  announced  that  the  FDa approved  pEmaZYrE (pemigatinib),  a  selective  fibroblast  growth  factor
receptor (FGFr) kinase inhibitor, for the treatment of adults with previously treated, unresectable locally advanced or metastatic
cholangiocarcinoma with an FGFr2 fusion or other rearrangement as detected by an FDa-approved test. pEmaZYrE is the first
and only FDa-approved treatment for this indication, which was approved under accelerated approval based on overall response
rate and duration of response (Dor).

Cholangiocarcinoma is a rare cancer that arises from the cells within the bile ducts. it is often diagnosed late (stages iii
and iv) and the prognosis is poor. the incidence of cholangiocarcinoma with FGFr2 fusions or rearrangements is increasing, and
it is currently estimated that there are 2,000-3,000 patients in the united States, Europe and Japan.

the  approval  of  pEmaZYrE  was  based  on  data  from  FiGht-202,  a  multi-center,  open-label,  single-arm  study
evaluating  pEmaZYrE  as  a  treatment  for  adults  with  cholangiocarcinoma.  in  FiGht-202,  and  in  patients  harboring  FGFr2
fusions or rearrangements (Cohort a), pEmaZYrE monotherapy resulted in an overall response rate of 36% (primary endpoint),
and median Dor of 9.1 months (secondary endpoint). FiGht-302, a phase iii trial of pemigatinib for the first-line treatment of
patients with cholangiocarcinoma and FGFr2 fusions or rearrangements, is ongoing.

We have retained all rights to pEmaZYrE globally, other than those granted to innovent Biologics, inc. to develop and

commercialize pemigatinib in hematology and oncology in mainland China, hong Kong, macau and taiwan.

ICLUSIG (ponatinib)

in June 2016, we acquired the European operations of ariaD pharmaceuticals, inc. and obtained an exclusive license to
develop  and  commercialize  iCluSiG  (ponatinib)  in  Europe  and  other  select  countries.  iCluSiG  is  a  kinase  inhibitor.  the
primary target for iCluSiG is BCr-aBl, an abnormal tyrosine kinase that is expressed in chronic myeloid leukemia (Cml) and
philadelphia-chromosome positive acute lymphoblastic leukemia (ph+ all).

in the European union, iCluSiG is approved for the treatment of adult patients with chronic phase, accelerated phase or
blast phase Cml who are resistant to dasatinib or nilotinib; who are intolerant to dasatinib or nilotinib and for whom subsequent
treatment with imatinib is not clinically appropriate; or who have the t315i mutation, or the treatment of adult patients with ph+
all  who  are  resistant  to  dasatinib;  who  are  intolerant  to  dasatinib  and  for  whom  subsequent  treatment  with  imatinib  is  not
clinically appropriate; or who have the t315i mutation.

Clinical Programs in Hematology and Oncology

Ruxolitinib and itacitinib

as  part  of  our  development  efforts  to  evaluate  JaK  inhibition  in  GvhD,  the  rEaCh  clinical  program  is  evaluating
ruxolitinib  in  patients  with  steroid-refractory  GvhD  and  includes  rEaCh2,  a  novartis-sponsored  phase  iii  trial  in  steroid-
refractory acute GvhD, and rEaCh3, a phase iii trial in steroid-refractory chronic GvhD that is co-sponsored by incyte and
novartis.

in october 2019, we and novartis announced that rEaCh2 met its primary endpoint of superior orr at Day 28 with
ruxolitinib treatment compared to best available therapy. no new safety signals were observed, and the ruxolitinib safety profile
in rEaCh2 was consistent with that seen in previously reported studies in steroid-refractory acute GvhD. in april 2020, we and
novartis announced that data from rEaCh2 were published in the new England Journal of medicine.

in  July  2020,  we  and  novartis  announced  that  rEaCh3  met  its  primary  endpoint  of  superior  orr  at  month  6  with
ruxolitinib treatment compared to best available therapy (Bat), as well as both key secondary endpoints, significantly improving
patient-reported  symptoms  and  failure-free  survival.  no new safety  signals  were  observed,  and  the  ruxolitinib  safety  profile  in
rEaCh3  was  consistent  with  that  seen  in  previously  reported  studies  in  steroid-refractory  chronic  GvhD.  additional  data
announced in December 2020 showed that best overall response (Bor) rate, defined as any response up to week 24, was achieved
in a significantly higher percentage of patients with ruxolitinib therapy compared to Bat. an snDa seeking FDa approval of
ruxolitinib in steroid-refractory chronic GvhD has been submitted.

a second JaK inhibitor in development is itacitinib, which is a selective JaK1 inhibitor. itacitinib is being evaluated in
GravitaS-309,  a  pivotal  phase  iii  trial  of  itacitinib  in  patients  with  steroid-naïve  chronic  GvhD.  the  FDa  has  granted
itacitinib orphan drug status for GvhD.

as part of our ongoing limBEr (leadership  in mpns BEyond ruxolitinib)  clinical  development  initiative,  which is
designed  to  improve  and  expand  therapeutic  options  for  patients  with  myeloproliferative  neoplasms,  we  are  evaluating
combinations of ruxolitinib with other therapeutic modalities, as well as developing a once-a-day formulation of ruxolitinib for
potential use as monotherapy and combination therapy.

Based on positive phase ii data, we have opened two pivotal trials of ruxolitinib in combination with parsaclisib (pi3Kδ) in
first-line  mF  (limBEr-313)  and  in  mF  patients  with  a  suboptimal  response  to  ruxolitinib  monotherapy  (limBEr-304),
respectively. additional phase ii trials combining ruxolitinib with investigational agents from our portfolio such as inCB57643
(BEt) and inCB00928 (alK2) in patients with mF are in preparation, and additional discovery and development initiatives are
also  ongoing  within  the  limBEr  program,  which  are  evaluating  both  internally-discovered  compounds,  including  itacitinib
(JaK1), and candidates from collaboration partners.

Tafasitamab

tafasitamab  is  an  anti-CD19  antibody  and  is  being  investigated  as  a  therapeutic  option  in  B  cell  malignancies  in  a
number of ongoing and planned combination trials. an open-label phase ii combination trial (l-minD) is investigating the safety
and  efficacy  of  tafasitamab  in  combination  with  lenalidomide  in  patients  with  relapsed  or  refractory  diffuse  large  B-cell
lymphoma (r/r DlBCl), and the ongoing phase iii B-minD trial is assessing the combination of tafasitamab and bendamustine
versus rituximab and bendamustine in r/r DlBCl. firstminD is a phase ib safety trial of tafasitamab as a first-line therapy for
patients  with  DlBCl,  and  frontminD,  a  placebo-controlled  phase  iii  trial  evaluating  tafasitamab  in  combination  with
lenalidomide  added  to  rituximab  plus  chemotherapy  (r-Chop)  as  a  first-line  therapy  for  patients  with  DlBCl,  is  planned  to
begin in 2021.

a placebo-controlled phase iii trial (inminD) of tafasitamab added to lenalidomide plus rituximab (r2) in patients with
relapsed or refractory follicular or marginal zone lymphomas is now recruiting patients, and we are preparing to initiate both a
proof-of-concept  study  of  tafasitamab  in  combination  with  parsaclisib  (pi3Kδ)  in  patients  with  relapsed  or  refractory  B-cell
malignancies and a proof-of-concept study of tafasitamab, lenalidomide and plamotamab in patients

with r/r DlBCl.

in may 2020, we announced the validation of the European marketing authorization application (maa) for tafasitamab
seeking  approval  of  tafasitamab  in  combination  with  lenalidomide,  followed  by  tafasitamab  monotherapy,  for  the  treatment  of
adult  patients  with  r/r  DlBCl;  the  validation  of  the  maa  by  the  European  medicines  agency  (Ema)  confirms  that  the
submission  is  ready  to  enter  the  formal  review  process.  in  January  2021, we announced  that  health  Canada  accepted  the  new
Drug Submission (nDS) for tafasitamab in combination with lenalidomide, followed by tafasitamab monotherapy, as a treatment
for adults with r/r DlBCl.

Pemigatinib

pemigatinib is a potent and selective inhibitor of the fibroblast growth factor receptor (FGFr) isoforms 1, 2 and 3 with
demonstrated  activity  in  preclinical  studies.  the  FGFr  family  of  receptor  tyrosine  kinases  can  act  as  oncogenic  drivers  in  a
number of liquid and solid tumor types.

We  initiated  the  FiGht  clinical  program  to  evaluate  pemigatinib  across  a  spectrum  of  cancers  that  are  driven  by
FGF/FGFr alterations. the program initially included three phase ii trials – FiGht-201 in patients with bladder cancer, FiGht-
202 in patients with cholangiocarcinoma, and FiGht-203 in patients with 8p11 myeloproliferative syndrome (8p11 mpn). Based
on  data  generated  from  these  ongoing  trials,  we  have  initiated  additional  trials,  including  FiGht-207,  which  is  a  solid  tumor-
agnostic trial evaluating pemigatinib in patients with driver-alterations of FGF/FGFr.

in  april  2020,  we  announced  the  FDa  approval  of  pemigatinib  as  pEmaZYrE  for  the  treatment  of  adults  with
previously treated, unresectable locally advanced or metastatic cholangiocarcinoma with an FGFr2 fusion or other rearrangement
as detected by an FDa-approved test. pemigatinib was previously granted Breakthrough therapy designation by the FDa as a
treatment for patients with previously treated, advanced/metastatic or unresectable FGFr2 translocated cholangiocarcinoma and
has Breakthrough therapy designation as a treatment for patients with myeloid/lymphoid neoplasms with FGFr1 rearrangement
(8p11 mpn) who have relapsed or are refractory to initial chemotherapy.

in January 2021, we announced that the Ema’s Committee  for medicinal  products for human use (Chmp) issued a
positive  opinion  recommending  the  conditional  marketing  authorization  of  pemigatinib  for  the  treatment  of  adults  with
unresectable  locally  advanced  or  metastatic  cholangiocarcinoma  with  an  FGFr2  fusion  or  rearrangement  that  is  relapsed  or
refractory, after at least one line of systemic therapy. in September 2020, we submitted a J-nDa seeking approval for pemigatinib
as a treatment for CCa in Japan. in october 2020, we announced that health Canada accepted the new Drug Submission (nDS)
for pemigatinib as a treatment for adults with previously treated, locally advanced or metastatic cholangiocarcinoma with FGFr2
fusion or other rearrangement.

Parsaclisib

the  pi3Kδ  pathway  mediates  oncogenic  signaling  in  B  cell  malignancies.  parsaclisib  is  a  pi3Kδ  inhibitor  that  has
demonstrated potency and selectivity in preclinical studies and has potential therapeutic utility in the treatment of patients with
lymphoma. We initiated the CitaDEl clinical program to evaluate parsaclisib in non-hodgkin lymphomas, and we are currently
running phase ii trials in follicular lymphoma, marginal zone lymphoma and mantle cell lymphoma. the FDa has granted orphan
drug designation and Fast track designation to parsaclisib  as a treatment  for patients  with follicular  lymphoma, marginal  zone
lymphoma and mantle cell lymphoma.

in December 2020, we announced preliminary results from the ongoing CitaDEl monotherapy development program,
which was designed  to enable registration  of parsaclisib.  results from  four cohorts  were presented  at the american  Society  of
hematology  (aSh),  including  in  r/r  follicular  lymphoma  (CitaDEl-203),  in  BtK-naïve  r/r  marginal  zone  lymphoma
(CitaDEl-204) and in both BtK-naïve and BtK-experienced r/r mantle cell lymphoma (CitaDEl-205).

Retifanlimab

in  october  2017,  we  and  macroGenics,  inc.  announced  an  exclusive  global  collaboration  and  license  agreement  for
macroGenics’  retifanlimab  (formerly  inCmGa0012),  an  investigational  monoclonal  antibody  that  inhibits  pD-1.  under  this
collaboration,  we  obtained  exclusive  worldwide  rights  for  the  development  and  commercialization  of  retifanlimab  in  all
indications.  the  molecule  is  currently  being  evaluated  both  as  monotherapy  and  in  combination  therapy  across  various  tumor
types. potentially registration-enabling trials in squamous cell carcinoma of the anal canal (SCaC), microsatellite instability-high
(mSi-h) endometrial cancer and merkel cell carcinoma are ongoing.

in January 2021, we announced that the FDa had accepted for priority review the Biologics license application (Bla)
for retifanlimab as a treatment for previously treated patients with advanced squamous cell carcinoma of the anal canal (SCaC)
who have progressed following standard platinum-based chemotherapy. the Bla submission was based on data from the phase
ii poD1um-202 trial of retifanlimab in patients with advanced SCaC who have progressed following standard platinum-based
chemotherapy,  preliminary  results of which were presented  at ESmo in September  2020. the phase iii poD1um-303 trial  of
retifanlimab in combination with platinum-based chemotherapy as a first-line treatment for patients with SCaC is underway.

the  phase  iii  poD1um-304  trial  is  evaluating  retifanlimab  in  combination  with  platinum-based  chemotherapy  as  a
first-line treatment for patients with non-small cell lung cancer (nSClC), and in october 2020, our collaboration partner Zai lab
announced dosing of the first patient in China.

retifanlimab has been granted Fast track designation for the treatment of certain patients with advanced or metastatic
mSi-h  or  Dna  mismatch  repair  (dmmr)  endometrial  cancer,  for  the  treatment  of  certain  patients  with  locally  advanced  or
metastatic  SCaC  and  for  the  treatment  of  merkel  cell  carcinoma  (mCC).  the  FDa  and  Ema  have  granted  orphan  drug
designation to retifanlimab as a treatment for patients with locally advanced or metastatic SCaC and the FDa has granted orphan
drug designation to retifanlimab as a treatment for patients with mCC.

Inflammation and AutoImmunity (IAI)

We do not yet have any approved products in iai.  in anticipation of the potential FDa approval of our most advanced
program, ruxolitinib cream for use in mild-to-moderate atopic dermatitis (aD), we recently established incyte Dermatology as a
new commercial franchise in the united States.

Clinical Programs in Dermatology

ruxolitinib  cream  is  a  potent,  selective  inhibitor  of  JaK1  and  JaK2  that  provides  the  opportunity  to  directly  target

diverse pathogenic pathways that underlie certain dermatologic conditions, including atopic dermatitis and vitiligo.

in  april  2020,  safety  and  efficacy  data  from  the  two  phase  iii  trials  in  the  truE-aD  program  evaluating  ruxolitinib
cream  in  mild-to-moderate  atopic  dermatitis  (aD)  were  presented  at  the  revolutionizing  atopic  Dermatitis  (raD)  virtual
symposium; both trials met their primary endpoints. the 44-week long-term safety and efficacy portion of both the truE-aD1
and truE-aD2 trials have been completed.

in  September  2020,  we  purchased  a  priority  review  voucher  (prv)  from  a  third  party,  with  the  intent  to  use  it  in
connection  with  our  submission  seeking  FDa  approval  of  ruxolitinib  cream  for  the  treatment  of  aD.  in  December  2020,  we
submitted an nDa along with the prv, seeking approval for ruxolitinib cream as a treatment for patients with aD.

aD is a skin disorder that causes long term inflammation of the skin resulting in itchy, red, swollen and cracked skin.
onset  can  occur  at  any  age,  but  is  more  common  in  infants  and  children.  in  the  united  States,  we  estimate  that  there  are
approximately 10 million diagnosed adolescent and adult patients with aD.

in June 2019, primary  endpoint data after  6 months of therapy from the phase ii trial  of ruxolitinib  cream  in patients
with vitiligo showed a significant benefit over vehicle control, and a global, pivotal phase iii program was initiated in September
2019. in october 2019, updated data from the phase ii trial showed, after 12 months of therapy, additional improvement in the
repigmentation of vitiligo lesions.

vitiligo  is  a  long-term  skin  condition  characterized  by  patches  of  the  skin  losing  their  pigment.  it  is  estimated  that
vitiligo affects 0.5-2% of the uS population and, therefore, there are at least 1.5 million patients in the united States with this
disorder. there are no FDa approved treatments for repigmentation of vitiligo lesions.

We  are  also  developing  inCB54707,  which  is  an  oral  small  molecule  selective  JaK1  inhibitor.  inCB54707  is
undergoing evaluation in patients with hidradenitis suppurativa (hS), a chronic skin condition where lesions develop as a result of
inflammation and infection of the sweat glands. in october 2020, initial results from the clinical program were presented and a
randomized phase iib trial of inCB54707 is underway in patients with hS.

Clinical Programs in Other IAI

a phase ii trial of parsaclisib in patients with autoimmune hemolytic anemia (aiha), a rare red blood cell disorder, is

also ongoing. the FDa has granted orphan drug designation to parsaclisib as a treatment for patients with aiha.

a phase ii trial of inCB00928 is in preparation for patients with fibrodysplasia ossificans progressiva (Fop), a disorder
in which muscle tissue and connective tissue are gradually replaced by bone. the FDa has granted Fast track designation and
orphan drug designation to inCB00928 as a treatment for patients with Fop.

Baricitinib

We have a second JaK1 and JaK2 inhibitor, baricitinib, which is subject to our collaboration agreement with lilly, in
which  lilly  received  exclusive  worldwide  development  and  commercialization  rights  to  the  compound  for  inflammatory  and
autoimmune diseases.

Rheumatoid Arthritis.   rheumatoid  arthritis  is  an  autoimmune  disease  characterized  by  aberrant  or  abnormal  immune
mechanisms that lead to joint inflammation and swelling and, in some patients, the progressive destruction of joints. rheumatoid
arthritis can also affect connective tissue in the skin and organs of the body.

Current rheumatoid arthritis treatments include the use of non-steroidal anti-inflammatory drugs, disease-modifying anti-
rheumatic drugs, such as methotrexate, and the newer biological response modifiers that target pro-inflammatory cytokines, such
as tumor necrosis factor, implicated in the pathogenesis of rheumatoid arthritis. none of these approaches to treatment is curative;
therefore,  there  remains  an  unmet  need  for  new  safe  and  effective  treatment  options  for  these  patients.  rheumatoid  arthritis  is
estimated to affect about 1% of the world’s population.

the  phase  iii  program  of  baricitinib  in  patients  with  rheumatoid  arthritis  incorporated  all  three  rheumatoid  arthritis
populations  (methotrexate  naïve,  biologic  naïve,  and  tumor  necrosis  factor  (tnF)  inhibitor  inadequate  responders);  used  event
rates to fully power the baricitinib program for structural comparison and non-inferiority vs. adalimumab; and evaluated patient-
reported outcomes. all four phase iii trials met their respective primary endpoints.

in  January  2016,  lilly  submitted  an  nDa  to  the  FDa  and  an  maa  to  the  Ema  for  baricitinib  as  treatment  for
rheumatoid  arthritis.  in  February  2017,  we  and  lilly  announced  that  the  European  Commission  approved  baricitinib  as
olumiant for the treatment of moderate-to-severe rheumatoid arthritis in adult patients who have responded inadequately to,
or who are intolerant to, one or more disease-modifying antirheumatic drugs (DmarDs). in July 2017, the Japanese ministry of
health,  labour  and  Welfare  (mhlW)  granted  marketing  approval  for  olumiant  for  the  treatment  of  rheumatoid  arthritis
(including the prevention of structural injury of joints) in patients with inadequate response to standard-of-care therapies. in June
2018, the FDa approved the 2mg dose of olumiant for the treatment of adults with moderately-to-severely active rheumatoid
arthritis (ra) who have had an inadequate response to one or more tumor necrosis factor (tnF) inhibitor therapies.

Atopic Dermatitis. lilly has conducted a phase iia trial and a phase iii program to evaluate the safety and efficacy of
baricitinib in patients with moderate-to-severe atopic dermatitis. the JaK-Stat pathway has been shown to play an essential
role  in  the  dysregulation  of  immune  responses  in  atopic  dermatitis.  therefore,  we  believe  that  inhibiting  cytokine  pathways
dependent on JaK1 and JaK2 may lead to positive clinical outcomes in aD.

in February 2019, we and lilly announced that baricitinib  met the primary  endpoint in BrEEZE-aD1 and BrEEZE-
aD2, two phase iii studies evaluating the efficacy and safety of baricitinib monotherapy for the treatment of adult patients with
moderate-to-severe aD and, in august 2019, we and lilly announced that baricitinib met the primary endpoint in BrEEZE-aD7,
a phase iii study evaluating the efficacy and safety of baricitinib in combination with standard-of-care topical corticosteroids in
patients with moderate-to-severe aD. in January 2020, we and lilly announced that baricitinib met the primary endpoint in both
BrEEZE-aD4  and  BrEEZE-aD5,  the  results  of  which  completed  the  placebo-controlled  data  program  intended  to  support
global registrations. an snDa for baricitinib has been submitted by lilly for the treatment of patients with aD.

in January 2020, lilly announced that baricitinib had been submitted for regulatory review in Europe as a treatment for
patients with moderate-to-severe aD. in october 2020, lilly announced that the European Commission approved baricitinib as
olumiant for the treatment of moderate-to-severe aD in adult patients who are candidates for systemic therapy. in December
2020, baricitinib was approved by the mhlW for the treatment of patients with moderate-to-severe aD.

Systemic Lupus Erythematosus. Systemic lupus erythematosus (SlE) is a chronic disease that causes inflammation. in
addition to affecting the skin and joints, it can affect other organs in the body such as the kidneys, the tissue lining the lungs and
heart, and the brain. lilly has conducted a phase ii trial to evaluate the safety and efficacy of

16

table of Contents

baricitinib in patients with SlE. Baricitinib’s activity profile suggests that it inhibits cytokines implicated in SlE such as type i
interferon  (iFn), type ii iFn-γ, il-6, and il-23 as well as other cytokines that may have a role in SlE, including granulocyte
macrophage  colony  stimulating  factor  (Gm-CSF)  and  il-12.  the  potential  impact  of  baricitinib  on  the  iFn  pathway  is  highly
relevant to SlE, as clinical and preclinical studies have established that this pathway is involved in the pathogenesis of SlE. lilly
is currently running two phase iii trials of baricitinib in patients with SlE, BravE i and BravE ii.

Alopecia  Areata.  alopecia  areata  is  an  autoimmune  disorder  in  which  the  immune  system  attacks  the  hair  follicles,
causing hair loss in patches. in march 2020, lilly announced that baricitinib received Breakthrough therapy designation for the
treatment of alopecia areata, based on the positive phase ii results of lilly’s adaptive phase ii/iii study BravE-aa1. the phase
iii  portion  of  BravE-aa1  is  ongoing,  as  is  a  second  phase  iii  study,  BravE-aa2,  in  adults  with  severe  or  very  severe
alopecia areata.

Capmatinib

Capmatinib is a potent and highly selective mEt inhibitor. the investigational compound has demonstrated inhibitory
activity  in  cell-based  biochemical  and  functional  assays  that  measure  mEt  signaling  and  mEt  dependent  cell  proliferation,
survival and migration. under our agreement, novartis received worldwide exclusive development and commercialization rights
to  capmatinib  and  certain  back-up  compounds  in  all  indications.  Capmatinib  is  being  evaluated  in  patients  with  hepatocellular
carcinoma, non-small cell lung cancer and other solid tumors, and may have potential utility as a combination agent.

mEt  is  a  clinically  validated  receptor  kinase  cancer  target.  abnormal  mEt  activation  in  cancer  correlates  with  poor
prognosis. Dysregulation of the mEt pathway triggers tumor growth, formation of new blood vessels that supply the tumor with
nutrients,  and  causes  cancer  to  spread  to  other  organs.  Dysregulation  of  the  mEt  pathway  is  seen  in  many  types  of  cancers,
including lung, kidney, liver, stomach, breast and brain.

in may 2020, we and novartis announced the FDa approval of capmatinib as taBrECta for the treatment of adult
patients with metastatic nSClC whose tumors have a mutation that leads to mEt exon 14 skipping (mEtex14) as detected by an
FDa-approved test. taBrECta is the first and only treatment approved to specifically target nSClC with this driver mutation
and is approved for first-line and previously treated patients regardless of prior treatment type.

the FDa approval of taBrECta was based on results from the pivotal GEomEtrY mono-1 study. in the mEtex14
population (n=97), the confirmed overall response rate was 68% and 41% among treatment-naive (n=28) and previously treated
patients  (n=69),  respectively,  based  on  the  Blinded  independent  review  Committee  (BirC)  assessment  per  rECiSt  v1.1.  in
patients  taking  taBrECta,  the  study  also  demonstrated  a  median  duration  of  response  of  12.6  months  in  treatment-naive
patients  (19  responders)  and  9.7  months  in  previously  treated  patients  (28  responders).  the  most  common  treatment-related
adverse  events  (aEs)  (incidence  ≥20%)  are  peripheral  edema,  nausea,  fatigue,  vomiting,  dyspnea,  and  decreased  appetite.  in
September 2020, we and novartis announced that GEomEtrY mono-1 results were published in the new England Journal of
medicine.

in  June  2020,  we  and  novartis  announced  that  the  mhlW  approved  taBrECta  for  mEtex14  mutation-positive

advanced and/or recurrent unresectable nSClC.

nSClC  is  the  most  common  type  of  lung  cancer,  impacting  more  than  2  million  people  per  year  globally.
approximately 3-4 percent of all patients with nSClC have tumors with a mutation that leads to mEt exon 14 skipping. though
rare,  this  mutation  is  an  indicator  of  especially  poor  prognosis  and  poor  responses  to  standard  therapies,  including
immunotherapy.

of the agreement, we received exclusive commercialization rights outside of the united States, and morphoSys and we have co-
commercialization rights in the united States, with respect to tafasitamab.  

COVID-19

in December 2019, coronavirus disease of 2019, or CoviD-19, was first reported in Wuhan, China. in march 2020, the
World  health  organization  declared  CoviD-19  a  pandemic  (“the  CoviD-19  pandemic”).    We  and  our  collaboration  partners
lilly and novartis initiated a number of clinical trials to address CoviD-19.

in april 2020, we announced the initiation of a phase iii clinical trial (ruxCoviD) to evaluate the efficacy and safety
of  ruxolitinib  plus  standard-of-care  (SoC),  compared  to  SoC  therapy  alone,  in  patients  not  on  mechanical  ventilation  and  who
have  CoviD-19  associated  cytokine  storm.  We  sponsored  this  collaborative  study  in  the  united  States  and  our  collaboration
partner novartis international pharmaceutical ltd. sponsored the study outside of the united States.

in December 2020, we announced initial results from ruxCoviD, where treatment with ruxolitinib plus SoC did not
prevent complications compared to SoC treatment alone in patients with CoviD-19 associated cytokine storm. the ruxCoviD
study has been completed and the data will be further analyzed to determine any potential impact on other studies of ruxolitinib in
patients with CoviD-19, including our Expanded access program in the united States, which allows eligible patients with severe
CoviD-19 associated cytokine storm to receive ruxolitinib.

a second phase iii clinical trial remains ongoing in multiple geographies, including the united States, to evaluate the
efficacy and safety of ruxolitinib plus SoC, compared to SoC therapy alone, in CoviD-19 patients on mechanical ventilation and
who have acute respiratory distress syndrome (arDS), a type of respiratory failure characterized by rapid onset of widespread
inflammation in the lungs. the SoC therapy is currently evolving and could be subject to change.

in april 2020, lilly announced that it has entered into an agreement with the national institute of allergy and infectious
Diseases  (niaiD),  part  of  the  national  institutes  of  health,  to  study  baricitinib  as  an  arm  in  niaiD's  adaptive  CoviD-19
treatment  trial  (aCtt-2).  the  study  is  investigating  the  efficacy  and  safety  of  baricitinib  as  a  potential  treatment  for
hospitalized patients diagnosed with CoviD-19 in the united States, and lilly is also planning an expansion to include Europe
and asia.

in  September  2020,  we  and  lilly  announced  initial  results  from  aCtt-2,  where  baricitinib  in  combination  with
remdesivir  reduced  the  time  to  recovery  in  comparison  with  remdesivir  alone.  additional  data  announced  in  october  2020
showed  that  baricitinib  plus  remdesivir  resulted  in  a  numerical  decrease  in  mortality  through  Day  29  compared  to  remdesivir
alone, with a more pronounced reduction seen in more severely ill patients.

in november 2020, we and lilly announced that the FDa issued an Emergency use authorization (Eua) for the

20

table of Contents

distribution  and  emergency  use  of  baricitinib  to  be  used  in  combination  with  remdesivir  in  hospitalized  adult  and  pediatric
patients two years of age or older with suspected or laboratory confirmed CoviD-19 who require supplemental oxygen, invasive
mechanical  ventilation,  or  extracorporeal  membrane  oxygenation.  in  December  2020,  we  and  lilly  announced  that  data  from
aCtt-2 supportive of the Eua were published in the new England Journal of medicine.

in  addition,  in  June  2020,  lilly  announced  that  the  first  patient  had  been  enrolled  in  a  phase  iii  randomized,  double-
blind, placebo–controlled study (Cov-BarriEr) to evaluate the efficacy and safety of baricitinib in hospitalized adults not on
mechanical ventilation and who have CoviD-19.

Incyte’s Approach to Drug Discovery and Development

our productivity in drug discovery is primarily a result of our core competency in medicinal chemistry which is tightly
integrated  with,  and  supported  by,  an  experienced  team  of  biologists  and  pharmaceutical  scientists  with  expertise  in  multiple
therapeutic  areas.  this  discovery  team  operates  in  concert  with  an  equally  experienced  drug  development  organization  with
expertise in clinical sciences, statistics, and regulatory affairs. our drug development organization manages our clinical programs
and  utilizes  clinical  research  organizations  (Cros),  expert  scientific  advisory  boards,  and  leading  consultants  and  suppliers  as
appropriate to ensure our clinical trials are conducted efficiently, effectively, and in accordance with regulatory and compliance
guidelines.  

to succeed in our objective to discover and advance novel therapeutics that address serious unmet medical needs, we
have  established  a  broad  range  of  discovery  capabilities  in-house,  including  target  validation,  high-throughput  screening,
medicinal chemistry, computational chemistry, pharmacological and translational sciences and aDmE (absorption, distribution,
metabolism  and  excretion)  assessment.  We  augment  these  capabilities  through  collaborations  with  academic  and  contract
laboratory resources with relevant expertise.

in  addition  to  our  small  molecule  expertise,  we  have  added  biotherapeutic  antibody  discovery  capabilities.  the
collaboration with agenus has provided us with access to their antibody discovery platform and provided us with both clinical
antibodies  and  pre-clinical  candidates.  We  have  expanded  our  discovery  scope  to  include  bispecific  antibodies  through  a
collaboration with merus. We are complementing these collaborations by building in-house antibody discovery, pharmacology,
aDmE and CmC capabilities and will partner these efforts with our small molecule portfolio.

Driven by a target- and pathway-centric discovery process, our pipeline has grown and is currently focused primarily in
the area of oncology. We conduct a limited number of discovery programs in parallel at any one time. this focus allows us to
allocate resources to our selected programs at a level that we believe is competitive with larger pharmaceutical companies. We
continually modify the resourcing of our discovery efforts with the goals of maximizing  information content when and where we
need it and ensuring that each program, regardless of stage, is executed in the most efficient and data-rich manner possible. We
believe this approach has played a critical role in the development of our product portfolio.

once our compounds reach clinical development, our objective is to rapidly progress the lead candidate into a proof-of-
concept clinical trial to quickly assess the therapeutic potential of the clinical candidate itself as well as its underlying mechanism
of  action.  this  information  is  then  used  to  evaluate  the  compound’s  development  opportunities,  identify  the  most  appropriate
indication or indications to pursue, and develop a clinical and regulatory plan to advance the molecule forward.

our  development  teams  are  responsible  for  ensuring  that  our  clinical  candidates  are  expeditiously  progressed  through
clinical safety, proof-of-concept, and formal efficacy/pivotal trials. our development teams include employees with expertise in
drug  development,  including  clinical  trial  design,  statistics,  regulatory  affairs,  medical  affairs,  pharmacovigilance  and  project
management. We have also built internal process chemistry and formulation teams that work closely with external Gmp contract
manufacturers to support our drug development efforts.

Incyte’s Commercial Strategy

our strategy is to develop and commercialize compounds that we have internally discovered or have acquired rights to in
the markets where we believe that a company of our size can successfully compete. We currently commercialize three compounds
in the united States and one in Europe.

in november 2011, we received regulatory approval of JaKaFi (ruxolitinib) in the united States for the treatment of
intermediate  or  high-risk  myelofibrosis.  Since  that  time,  we  have  focused  on  increasing  utilization  of  JaKaFi  in  this  patient
population.  in  December  2014,  JaKaFi  was  approved  for  the  treatment  of  patients  with  polycythemia  vera  who  have  had  an
inadequate  response  to  or  are  intolerant  of  hydroxyurea.  in  may  2019,  JaKaFi  was  approved  for  the  treatment  of  steroid‐
refractory acute GvhD in adult and pediatric patients 12 years and older.

in april 2020, we received regulatory approval of pEmaZYrE (pemigatinib) in the united States for the treatment of
adults with previously treated, unresectable locally advanced or metastatic cholangiocarcinoma (CCa) with an FGFr2 fusion or
other  rearrangement.  We  are  focused  on  increasing  the  utilization  of  molecular  profiling  in  CCa  to  support  identification  of
appropriate patients for pEmaZYrE.

in  January  2020,  we  and  morphoSys  aG  entered  into  a  collaboration  and  license  agreement  to  further  develop  and
commercialize morphoSys' proprietary anti-CD19 antibody tafasitamab globally. in July of 2020, monJuvi (tafasitamab-cxix),
in combination with lenalidomide, was FDa approved for the treatment of adult patients with relapsed or refractory diffuse large
B-cell  lymphoma  (DlBCl)  not  otherwise  specified,  including  DlBCl  arising  from  low  grade  lymphoma,  and  who  are  not
eligible for autologous stem cell transplant. monJuvi is being co-commercialized by us and morphoSys in the united States.

We  have  expanded  the  marketing,  medical,  sales  and  operational  infrastructure  to  support  the  commercialization  of

JaKaFi, pEmaZYrE and monJuvi in the united States.

iCluSiG is approved in the European union for the treatment of adult patients with Cml who are resistant to dasatinib
or  nilotinib;  who  are  intolerant  to  dasatinib  or  nilotinib  and  for  whom  subsequent  treatment  with  imatinib  is  not  clinically
appropriate, or who have the t315i mutation. iCluSiG is also indicated in adult patients with philadelphia positive aml who
are  resistant  to  dasatinib;  who  are  intolerant  to  dasatinib  and  for  whom  subsequent  treatment  with  imatinib  is  not  clinically
appropriate, or who have the t315i mutation. We are focused on increasing the utilization of iCluSiG in this patient population
within our territory as appropriate.

We are continuing to expand our marketing, medical and operational infrastructure within the united States and outside

of the united States to prepare for potential approval of other products.

For certain other compounds, including rights to ruxolitinib outside the united States and global rights to capmatinib,
which have both been licensed to novartis, and global rights to baricitinib, which have been licensed to lilly, we have established
and may in the future establish collaborations or strategic relationships to support development and commercialization in certain
territories or therapeutic areas where we do not have or do not want to build expertise. We believe the key benefits to entering
into  such  strategic  relationships  include  the  potential  to  expedite  the  development  and  commercialization  of  certain  of  our
compounds, as well as the opportunity to receive upfront payments and future milestones and royalties in exchange for certain
rights to those compounds.

Patents and Other Intellectual Property

We regard the protection of patents and other enforceable intellectual property rights that we own or license as critical to
our  business  and  competitive  position.  accordingly,  we  rely  on  patent,  trademark,  trade  secret  and  copyright  law,  as  well  as
nondisclosure and other contractual arrangements, to protect our intellectual property. We have established a patent portfolio of
patents  and  patent  applications  owned  or  licensed  by  us  that  cover  aspects  of  all  our  drug  products  and  drug  candidates.  the
patents  and  patent  applications  relating  to  our  drug  products  and  drug  candidates  generally  include  claims  directed  to  the
compounds, methods of using the compounds, formulations of the compounds, pharmaceutical salt forms of the compounds, and
methods of manufacturing the compounds. our policy is to pursue patent applications on

22

table of Contents

inventions  and  discoveries  that  we  believe  are  commercially  important  to  the  development  and  growth  of  our  business.  the
following table sets forth the status of the patents and patent applications in the united States, the European union, and Japan for
our  approved  medicines  and  for  those  compounds  in  our  portfolio  that  have  been  submitted  to  regulatory  authorities  seeking

patents  extend  for  varying  periods  according  to  the  date  of  patent  filing  or  grant  and  the  legal  term  of  patents  in  the
various countries where patent protection is obtained. the actual protection afforded by a patent, which can vary from country to
country, depends on the type of patent, the scope of its coverage and the availability of legal remedies in the country.

We  may  seek  to  license  rights  relating  to  technologies,  drug  candidates  or  drug  products  in  connection  with  our  drug
discovery and development programs and commercialization activities. under these licenses, such as our licenses from agenus,
ariaD/takeda,  Calithera,  macroGenics,  morphoSys,  and  merus,  we  may  be  required  to  pay  up-front  fees,  license  fees,
milestone payments and royalties on sales of future products.

although  we  believe  our  rights  under  patents  and  patent  applications  provide  a  competitive  advantage,  the  patent
positions of pharmaceutical and biotechnology companies are highly uncertain and involve complex legal and factual questions.
We may not be able to develop patentable products or processes, and may not be able to obtain patents in the united States or
elsewhere from pending applications. Even if patent claims are allowed, the claims may not issue, or in the event of issuance, may
not be valid or enforceable or may not be sufficient to protect the technology owned by or licensed to us or provide us with a
competitive advantage. any patent or other intellectual property rights that we own or obtain may be circumvented, challenged or
invalidated by our competitors. others may have patents that relate to our business or technology and that may prevent us from
marketing our drug candidates unless we are able to obtain a license to those patents. in addition, litigation or other proceedings
may be necessary to defend against claims of infringement, to enforce patents, to protect our other intellectual property rights, to
determine  the  scope  and  validity  of  the  proprietary  rights  of  third  parties  or  to  defend  ourselves  in  patent  or  other  intellectual
property right suits brought by third parties. We could incur substantial costs in such litigation or other proceedings. an adverse
outcome in any such litigation or proceeding could subject us to significant liability.

23

With  respect  to  proprietary  information  that  is  not  patentable,  and  for  inventions  for  which  patents  are  difficult  to
enforce, we rely on trade secret protection and confidentiality agreements to protect our interests. While we require all employees,
consultants and potential business partners to enter into confidentiality agreements, we may not be able to adequately protect our
trade secrets or other proprietary information. others may independently develop substantially equivalent proprietary information
and techniques or otherwise gain access to our trade secrets.

Competition

our drug discovery, development and commercialization activities face, and will continue to face, intense competition
from  organizations  such  as  pharmaceutical  and  biotechnology  companies,  as  well  as  academic  and  research  institutions  and
government  agencies.  We  face  significant  competition  from  organizations,  particularly  fully  integrated  pharmaceutical
companies, that are pursuing pharmaceuticals that are competitive with JaKaFi, iCluSiG, pEmaZYrE, monJuvi, and our
drug candidates.

many  companies  and  institutions,  either  alone  or  together  with  their  collaborative  partners,  have  substantially  greater
financial resources, larger drug discovery, development and commercial staffs and significantly greater experience than we do in:

●

●

●

●

drug discovery;

developing products;

undertaking preclinical testing and clinical trials;

obtaining FDa and other regulatory approvals of products; and

● manufacturing, marketing, distributing and selling products.

accordingly, our competitors may succeed in obtaining patent protection, receiving FDa and other regulatory approval

or commercializing products that compete with JaKaFi, iCluSiG, pEmaZYrE, monJuvi or our drug candidates.

in  addition,  any  drug  candidate  that  we  successfully  develop  may  compete  with  existing  therapies  that  have  long

histories of safe and effective use. Competition may also arise from:

●

●

●

other drug development technologies and methods of preventing or reducing the incidence of disease;

new compounds; or

other classes of therapeutic agents.

We  face  and  will  continue  to  face  intense  competition  from  other  companies  for  collaborative  arrangements  with
pharmaceutical  and  biotechnology  companies,  for  establishing  relationships  with  academic  and  research  institutions  and  for
licenses  to drug candidates  or proprietary  technology. these competitors,  either  alone or with their collaborative  partners,  may
succeed in developing products that are more effective or commercially successful than ours.

our ability to compete successfully will depend, in part, on our ability to:

●

●

develop proprietary products;

develop and maintain products that reach the market first, are technologically superior to and/or are of lower cost
than other products in the market;

24

table of Contents

●

●

●

attract and retain scientific, product development and sales and marketing personnel;

obtain patent or other proprietary protection for our products and technologies;

obtain required regulatory approvals; and

● manufacture, market, distribute and sell any products that we develop.

in  a  number  of  countries,  including  in  particular,  developing  countries,  government  officials  and  other  groups  have
suggested  that  pharmaceutical  companies  should  make  drugs  available  at  a  low  cost.  in  some  cases,  governmental  authorities
have  indicated  that  where  pharmaceutical  companies  do  not  do  so,  their  patents  might  not  be  enforceable  to  prevent  generic
competition. Some major pharmaceutical companies have greatly reduced prices for their drugs in certain developing countries. if
certain countries do not permit enforcement of any of our patents, sales of our products in those countries, and in other countries
by  importation  from  low-price  countries,  could  be  reduced  by  generic  competition  or  by  parallel  importation  of  our  product.
alternatively,  governments  in  those  countries  could  require  that  we  grant  compulsory  licenses  to  allow  competitors  to
manufacture  and  sell  their  own  versions  of  our  products  in  those  countries,  thereby  reducing  our  product  sales,  or  we  could
respond to governmental concerns by reducing prices for our products. in all of these situations, our results of operations could be
adversely affected.

Government Regulation

our ongoing research and development activities and any manufacturing and marketing of our approved drug products
and our drug candidates are subject to extensive regulation by numerous governmental authorities in the united States and other
countries.  Before  marketing  in  the  united  States,  any  drug  developed  by  us  must  undergo  rigorous  preclinical  testing,  clinical
trials, and an extensive regulatory clearance process implemented by the FDa under the united States Food, Drug and Cosmetic
act  and  its  implementing  regulations  and,  in  the  case  of  biologics,  the  public  health  Service  act.  the  FDa  regulates,  among
other  things,  the  research,  development,  testing,  manufacture,  safety,  efficacy,  record-keeping,  labeling,  storage,  approval,
advertising, promotion, sale and distribution and import and export, of these products.  

FDA Review and Approval Process

the regulatory review and approval process is lengthy, expensive and uncertain. the steps generally required before a

drug may be marketed in the united States include:

●

●

●

●

●

●

preclinical laboratory tests, animal studies and formulation studies in compliance with the FDa’s Good laboratory
practice and Good manufacturing practice regulations;

submission to the FDa of an investigational new Drug application (inD) for human clinical testing, which must
become effective before human clinical trials may commence;

performance  of  adequate  and  well-controlled  clinical  trials  in  three  phases,  as  described  below,  to  establish  the
safety and efficacy of the drug for each indication;

submission of an nDa or Biologics license application (Bla) to the FDa for review;

random inspections of clinical sites to ensure validity of clinical safety and efficacy data;

satisfactory  completion  of  an  FDa  inspection  of  the  manufacturing  facility  or  facilities  at  which  the  drug  is
produced to assess compliance with current good manufacturing practices;

●

FDa approval of the nDa or Bla; and

25

table of Contents

●

payment of user and establishment fees, if applicable.

Similar  requirements  exist  within  foreign  agencies  as  well.  the  time  required  to  satisfy  FDa  requirements  or  similar
requirements of foreign regulatory agencies may vary substantially based on the type, complexity and novelty of the product or
the targeted disease.

preclinical  testing  includes  laboratory  evaluation  of  product  pharmacology,  drug  metabolism,  and  toxicity  which
includes animal studies, to assess potential safety and efficacy as well as product chemistry, stability, formulation, development,
and testing. the results of the preclinical tests, together with manufacturing information and analytical data, are submitted to the
FDa as part of an inD. an inD will automatically become effective 30 days after receipt by the FDa, unless before that time,
the FDa raises safety concerns or questions about the conduct of the clinical trial(s) included in the inD. in the latter case, the
inD sponsor and the FDa must resolve any outstanding FDa concerns or questions before clinical trials can proceed. We cannot
be sure that submission of an inD will result in the FDa allowing clinical trials to commence.

Clinical trials involve the administration of the investigational drug to human subjects under the supervision of qualified
investigators  and  in  accordance  with  good  clinical  practices  regulations  covering  the  protection  of  human  subjects.  these
regulations require all research subjects to provide informed consent. Clinical trials are conducted under protocols detailing the
objectives  of  the  study,  the  parameters  to  be  used  in  monitoring  safety,  and  the  effectiveness  criteria  to  be  evaluated.  Each
protocol must be submitted to the FDa as part of the inD and each trial must be reviewed and approved by an institutional review
board (irB) before it can begin.

Clinical trials typically are conducted  in three sequential phases, but the phases may overlap or be combined. phase i
usually involves the initial introduction of the investigational drug into healthy volunteers to evaluate its safety, dosage tolerance,
absorption,  metabolism,  distribution  and  excretion.  phase  ii  usually  involves  clinical  trials  in  a  limited  patient  population  to
evaluate  dosage  tolerance  and  optimal  dosage,  identify  possible  adverse  effects  and  safety  risks,  and  evaluate  and  gain
preliminary evidence of the efficacy of the drug for specific indications. phase iii clinical trials usually further evaluate clinical
efficacy  and  safety  by  testing  the  drug  in  its  final  form  in  an  expanded  patient  population,  providing  statistical  evidence  of
efficacy and safety, and providing an adequate basis for labeling. We cannot guarantee that phase i, phase ii or phase iii testing
will be completed successfully within any specified period of time, if at all. Furthermore, we, the irB, or the FDa may suspend
clinical  trials  at  any  time  on  various  grounds,  including  a  finding  that  the  subjects  or  patients  are  being  exposed  to  an
unacceptable health risk.

as  a  separate  amendment  to  an  inD,  a  clinical  trial  sponsor  may  submit  to  the  FDa a  request  for  a  Special  protocol
assessment (Spa). under the Spa procedure, a sponsor may seek the FDa’s agreement on the design and size of a clinical trial
intended to form the primary basis of an effectiveness claim. if the FDa agrees in writing, its agreement may not be changed after
the trial begins, except when agreed by FDa or in limited circumstances, such as when a substantial scientific issue essential to
determining  the  safety  and  effectiveness  of  a  drug  candidate  is  identified  after  a  phase  iii  clinical  trial  is  commenced  and
agreement is obtained with the FDa. if the outcome of the trial is successful, the sponsor will ordinarily be able to rely on it as
the  primary  basis  for  approval  with  respect  to  effectiveness.  however,  additional  trials  could  also  be  requested  by the  FDa to
support  approval,  and  the  FDa may  make  an  approval  decision  based  on  a  number  of  factors,  including  the  degree  of  clinical
benefit  as  well  as  safety.  the  FDa  is  not  obligated  to  approve  an  nDa  or  Bla  as  a  result  of  an  Spa  agreement,  even  if  the
clinical outcome is positive.

Even after initial FDa approval has been obtained, post-approval trials, or phase iv studies, may be required to provide
additional data, and will be required to obtain approval for the sale of a product as a treatment for a clinical indication other than
that for which the product was initially tested and approved. also, the FDa will require post-approval safety reporting to monitor
the side effects of the drug. results of post-approval programs may limit or expand the indication or indications for which the
drug  product  may  be  marketed.  Further,  if  there  are  any  requests  for  modifications  to  the  initial  FDa  approval  for  the  drug,
including changes in indication, manufacturing process, manufacturing facilities, or labeling, a supplemental nDa or Bla may
be required to be submitted to the FDa.

the  length  of  time  and  related  costs  necessary  to  complete  clinical  trials  varies  significantly  and  may  be  difficult  to

predict. Clinical results are frequently susceptible to varying interpretations that may delay, limit or prevent regulatory

26

table of Contents

approvals. additional factors that can cause delay or termination of our clinical trials, or cause the costs of these clinical trials to
increase, include:

●

●

●

●

●

●

●

slow patient enrollment due to the nature of the protocol, the proximity of patients to clinical sites, the eligibility
criteria for the study, competition with clinical trials for other drug candidates or other factors;

inadequately trained or insufficient personnel at the study site to assist in overseeing and monitoring clinical trials;

delays in approvals from a study site’s irB;

longer than anticipated  treatment  time required to demonstrate effectiveness  or determine the appropriate  product
dose;

lack of sufficient supplies of the drug candidate for use in clinical trials;

adverse medical events or side effects in treated patients; and

lack of effectiveness of the drug candidate being tested.

any drug is likely to produce some toxicities or undesirable side effects in animals and in humans when administered at
sufficiently high doses and/or for sufficiently long periods of time. unacceptable toxicities or side effects may occur at any dose
level,  and  at  any  time  in  the  course  of  animal  studies  designed  to  identify  unacceptable  effects  of  a  drug  candidate,  known  as
toxicological studies, or in clinical trials of our drug candidates. the appearance of any unacceptable toxicity or side effect could
cause  us  or  regulatory  authorities  to  interrupt,  limit,  delay  or  abort  the  development  of  any  of  our  drug  candidates,  and  could
ultimately prevent their marketing approval by the FDa or foreign regulatory authorities for any or all targeted indications.

the  FDa’s  fast  track,  breakthrough  therapy,  accelerated  approval,  and  priority  review  designation  programs  are
intended  to  facilitate  the  development  and  expedite  the  review  and  approval  of  drug  candidates  intended  for  the  treatment  of
serious  or  life-threatening  conditions  and  that  demonstrate  the  potential  to  address  unmet  medical  needs  for  these  conditions.
under  these  programs,  FDa  can,  for  example,  review  portions  of  an  nDa  or  Bla  for  a  drug  candidate  before  the  entire
application is complete, thus potentially beginning the review process at an earlier time.

We cannot guarantee that the FDa will grant any of our requests for any of these expedited program designations, that
any such designations would affect the time of review or that the FDa will approve the nDa or Bla submitted for any of our
drug candidates, whether or not these designations are granted. additionally, FDa approval of a product can include restrictions
on  the  product’s  use  or  distribution  (such  as  permitting  use  only  for  specified  medical  conditions  or  limiting  distribution  to
physicians  or  facilities  with  special  training  or  experience).  approval  of  such  designated  products  can  be  conditioned  on
additional clinical trials after approval.

Sponsors submit the results of preclinical studies and clinical trials to the FDa as part of an nDa or Bla. nDas and
Blas  must  also  contain  extensive  product  manufacturing  information  and  proposed  labeling.  upon  receipt,  the  FDa  initially
reviews the nDa or Bla to determine whether it is sufficiently complete to initiate a substantive review. if the FDa identifies
deficiencies that would preclude substantive review, the FDa will refuse to accept the nDa or Bla and will inform the sponsor
of the deficiencies  that must be corrected  prior to resubmission.  if the FDa accepts  the submission for review (then deemed a
“filing”), the FDa typically completes the nDa or Bla review within a pre-determined time frame. under the prescription Drug
user  Fee  act,  the  FDa  agrees  to  review  nDas  and  Blas  under  either  a  standard  review  or  priority  review.  FDa  procedures
provide for priority review of nDas and Blas submitted for drugs that, compared to currently marketed products, if any, offer a
significant improvement in the treatment, diagnosis or prevention of a disease. the FDa seeks to review nDas and Blas that
are granted priority status more quickly than nDas and Blas given standard review status. the FDa’s stated policy is to act on
90% of priority  nDas and Blas within eight months of receipt  (or six months after filing,  which occurs within 60 days after
nDa or Bla submission). although the FDa

27

table of Contents

historically has not met these goals, the agency has made significant improvements in the timeliness of the review process. nDa
and Bla review often extends beyond anticipated completion dates due to FDa requests for additional data or clarification, the
FDa’s  decision  to  have  an  advisory  committee  review,  and  difficulties  in  scheduling  an  advisory  committee  meeting.  the
recommendations of an advisory committee are not binding on the FDa.

to obtain FDa approval to market a product, we must demonstrate that the product is safe and effective for the patient
population that will be treated. if regulatory approval of a product is granted, the approval will be limited to those disease states
and conditions for which the product is safe and effective, as demonstrated through clinical trials. marketing or promoting a drug
for  an  unapproved  indication  is  prohibited.  Furthermore,  approval  may  entail  requirements  for  post-marketing  studies  or  risk
evaluation and mitigation strategies, including the need for patient and/or physician education, patient registries, medication or
similar guides, or other restrictions on the distribution of the product. if an nDa or Bla does not satisfy applicable regulatory
criteria,  the  FDa  may  deny  approval  of  an  nDa  or  Bla  or  may  issue  a  complete  response,  and  require,  among  other  things,
additional clinical data or analyses.

the orphan Drug act provides incentives to manufacturers to develop and market drugs for rare diseases and conditions
affecting  fewer  than  200,000  persons  in  the  united  States  at  the  time  of  application  for  orphan  drug  designation.  the  first
developer  to receive  FDa marketing  approval  for an  orphan drug  is  entitled  to  a seven  year  exclusive  marketing  period  in  the
united  States  for  the  orphan  drug  indication.  however,  a  drug  that  the  FDa  considers  to  be  clinically  superior  to,  or  different
from, another approved orphan drug, even though for the same indication, may also obtain approval in the united States during
the seven year exclusive marketing period.

Regulation of Manufacturing Process

Even  when  nDa  or  Bla  approval  is  obtained,  a  marketed  product,  such  as  JaKaFi,  its  manufacturer  and  its
manufacturing  facilities  are  subject  to  continual  review  and  periodic  inspections  by  the  FDa.  the  manufacturing  process  for
pharmaceutical  products  is  highly  regulated  and  regulators  may  shut  down  manufacturing  facilities  that  they  believe  do  not
comply  with  regulations.  Discovery  of  previously  unknown  problems  with  a  product,  manufacturer  or  facility  may  result  in
restrictions  on  the  product,  manufacturer  or  facility,  including  costly  recalls  or  withdrawal  of  the  product  from  the  market.
manufacturing facilities are always subject to inspection by the applicable regulatory authorities.

We  and  our  third-party  manufacturers  are  subject  to  current  Good  manufacturing  practices,  which  are  extensive
regulations governing manufacturing processes, including but not limited to stability testing, record keeping and quality standards
as  defined  by  the  international  Council  for  harmonisation  of  technical  requirements  for  pharmaceuticals  for  human  use,  or
iCh, FDa and the European medicines agency. Similar regulations are in effect in other countries. manufacturing facilities are
subject to inspection by the applicable regulatory authorities and are subject to manufacturing licenses where applicable. these
facilities,  whether  our  own  or  our  contract  manufacturers,  must  be  inspected  before  we  can  use  them  in  commercial
manufacturing  of  our  related  products.  We  or  our  contract  manufacturers  may  not  be  able  to  comply  with  applicable  Good
manufacturing practices and FDa or other regulatory requirements. if we or our contract manufacturers fail to comply, we or our
contract  manufacturers  may  be  subject  to  legal  or  regulatory  action,  such  as  suspension  of  manufacturing  license,  seizure  of
product, or voluntary recall of product. Furthermore, continued compliance with applicable Good manufacturing practices will
require continual expenditure of time, money and effort on the part of us or our contract manufacturers in the areas of production
and quality control and record keeping and reporting, in order to ensure full compliance.

Post-Approval Regulation

any  products  manufactured  or  distributed  by  us  pursuant  to  FDa  approvals  are  subject  to  pervasive  and  continuing
regulation  by  the  FDa,  including  record-keeping  requirements,  reporting  of  adverse  experiences  with  the  drug  and  other
reporting, advertising and promotion restrictions. the FDa’s rules for advertising and promotion require, among other things, that
our  promotion  be  fairly  balanced  and  adequately  substantiated  by  clinical  studies,  and  that  we  not  promote  our  products  for
unapproved  uses.  We  must  also  submit  appropriate  new  and  supplemental  applications  and  obtain  FDa  approval  for  certain
changes to the approved product, product labeling or manufacturing process. on its own initiative, the FDa may require changes
to the labeling of an approved drug if it becomes aware of new safety information that the agency believes should be included in
the approved drug’s labeling. the FDa also enforces the requirements of the

28

table of Contents

prescription  Drug  marketing  act,  or  pDma,  which,  among  other  things,  imposes  various  requirements  in  connection  with  the
distribution of product samples to physicians.

in addition to inspections related to manufacturing, we are subject to periodic unannounced inspections by the FDa and
other regulatory bodies related to the other regulatory requirements that apply to marketed drugs manufactured or distributed by
us.  the  FDa  also  may  conduct  periodic  inspections  regarding  our  review  and  reporting  of  adverse  events,  or  related  to
compliance with the requirements of the pDma concerning the handling of drug samples. When the FDa conducts an inspection,
the  inspectors  will  identify  any  deficiencies  they  believe  exist  in  the  form  of  a  notice  of  inspectional  observations.  the
observations  may be more or less significant.  if we receive  a notice of inspectional  observations,  we likely will be required  to
respond in writing, and may be required to undertake corrective and preventive actions in order to address the FDa’s concerns.

there  are  a  variety  of  state  laws  and  regulations  that  apply  in  the  states  or  localities  where  JaKaFi  and  our  drug
candidates are or may be marketed. For example, we must comply with state laws that require the registration of manufacturers
and  wholesale  distributors  of  pharmaceutical  products  in  that  state,  including,  in  certain  states,  manufacturers  and  distributors
who ship products into the state even if such manufacturers or distributors have no place of business within the state. Some states
also  impose  requirements  on  manufacturers  and  distributors  to  establish  the  pedigree  of  product  in  the  chain  of  distribution,
including some states that require manufacturers and others to adopt new technology capable of tracking and tracing product as it
moves through the distribution chain. any applicable state or local regulations may hinder our ability to market, or increase the
cost of marketing, our products in those states or localities.

the FDa’s policies may change and additional government regulations may be enacted which could impose additional
burdens or limitations on our ability to market products after approval. moreover, increased attention to the containment of health
care costs in the united States and in foreign markets could result in new government regulations which could have a material
adverse effect on our business. We cannot predict the likelihood, nature or extent of adverse governmental regulation which might
arise from future legislative or administrative action, either in the united States or abroad.

Marketing Exclusivity

the FDa may grant five years of exclusivity in the united States for the approval of nDas for new chemical entities,
and three years of exclusivity for supplemental nDas, for among other things, new indications, dosages or dosage forms of an
existing drug if new clinical investigations that were conducted or sponsored by the applicant are essential to the approval of the
supplemental application. additionally, six months of marketing exclusivity in the united States is available if, in response to a
written request from the FDa, a sponsor submits and the agency accepts requested information relating to the use of the approved
drug  in  the  pediatric  population.  the  six  month  pediatric  exclusivity  is  added  to  any  existing  patent  or  non-patent  exclusivity
period for which the drug is eligible. orphan drug products are also eligible for pediatric exclusivity if the FDa requests and the
company  completes  pediatric  clinical  trials.  under  the  Biologics  price  Competition  and  innovation  act,  the  FDa  may  grant
12 years of data exclusivity for innovative biological products.

Foreign Regulation

outside the united States, our ability to market a product is contingent upon receiving a marketing authorization from
the appropriate regulatory authorities. the requirements governing the conduct of clinical trials, marketing authorization, pricing
and reimbursement vary widely from country to country. at present, foreign marketing authorizations are applied for at a national
level, although within the European union (Eu) registration procedures are available to companies wishing to market a product in
more than one Eu member state. if the competent regulatory authority is satisfied that adequate evidence of safety, quality and
efficacy has been presented, a marketing authorization may be granted. this foreign regulatory approval process involves all of
the risks associated with FDa approval discussed above and may also include additional risks.

Whether  or  not  we  obtain  FDa  approval  for  a  product,  we  must  obtain  the  requisite  approvals  from  regulatory
authorities  in  non-uS  countries  prior  to  the  commencement  of  clinical  trials  or  marketing  of  the  product  in  those  countries.
Certain countries outside of the united States have a process that requires the submission of a clinical trial application, or

29

table of Contents

Cta,  much  like  an  inD  prior  to  the  commencement  of  human  clinical  trials.  in  Europe,  a  Cta  must  be  submitted  to  the
competent national health authority and to independent ethics committees in each country in which a company plans to conduct
clinical trials. once the Cta is approved in accordance with a country’s requirements, clinical trial development may proceed in
that country and are conducted in accordance with GCp and other applicable regulatory requirements.

to  obtain  regulatory  approval  of  an  investigational  drug  under  Eu  regulatory  systems,  we  must  submit  a  marketing
authorization application (maa). this application is similar to the nDa in the united States, with the exception of, among other
things, regional and/or country-specific document requirements. Drugs can be authorized in the Eu by using (i) the centralized
authorization  procedure,  (ii)  the  mutual  recognition  procedure,  (iii)  the  decentralized  procedure  or  (iv)  national  authorization
procedures.

the European medicines agency implemented the centralized procedure for the approval of human drugs to facilitate
marketing authorizations that are valid throughout the Eu. this procedure results in a single marketing authorization granted by
the  European  Commission  that  is  valid  across  the  Eu.  under  the  centralized  procedure,  the  maximum  timeframe  for  the
evaluation of a marketing authorization application by the Ema is 210 days (excluding clock stops, when additional written or
oral information is to be provided by the applicant in response to questions asked by the Committee for medicinal products for
human use). a positive opinion on the maa by the Chmp then needs to be endorsed by the European Commission. accelerated
assessment  might  be  granted  by  the  Chmp  in  exceptional  cases,  in  which  case  the  Ema  ensures  that  the  evaluation  for  the
opinion of the Chmp is completed within 150 days (excluding clock stops) and the opinion issued thereafter.

the  mutual  recognition  procedure  (mrp)  for  the  approval  of  human  drugs  is  an  alternative  approach  to  facilitate
individual  national  marketing  authorizations  within  the  Eu.  the  mrp  may  be  applied  for  all  human  drugs  for  which  the
centralized  procedure  is  not obligatory.  the  mrp is  based on the  principle  of  the mutual  recognition  by Eu member  states  of
their  respective  national  marketing  authorizations.  Based  on  a  marketing  authorization  in  the  reference  member  state,  the
applicant may apply for marketing authorizations in other member states. in such case, the reference member state shall update its
existing assessment report about the drug. after the assessment is completed, copies of the report are sent to all member states,
together with the approved summary of product characteristics, labeling and package leaflet. the concerned member states then
recognize  the decision of the reference  member  state and the summary of product characteristics,  labeling  and package leaflet.
national marketing authorizations shall be granted within 30 days after acknowledgement of the agreement.

Should any member State refuse to recognize the marketing authorization by the reference member state, the member
states  shall  make  all  efforts  to  reach  a  consensus.  if  this  fails,  the  procedure  is  submitted  to  an  Ema  scientific  committee  for
arbitration.  the  opinion  of  this  Ema  Committee  is  then  forwarded  to  the  Commission,  for  the  start  of  the  decision  making
process. as in the centralized procedure, this process entails consulting various European Commission Directorates General and
the Standing Committee on human medicinal products or veterinary medicinal products, as appropriate.

legislation similar to the orphan Drug act has been enacted in other countries outside of the united States, including
the Eu. the orphan legislation in the Eu is available for therapies addressing conditions that affect five or fewer out of 10,000
persons,  are  life-threatening  or  chronically  debilitating  conditions  and  for  which  no  satisfactory  treatment  is  authorized.  the
market exclusivity period is for ten years, although that period can be reduced to six years if, at the end of the fifth year, available
evidence establishes that the product does not justify maintenance of market exclusivity.

For other countries outside of the Eu, such as non-Eu countries in Eastern Europe, middle-East, latin america, Japan
or other countries in asia, the requirements governing the conduct of clinical trials, product licensing, pricing and reimbursement
vary.  in  all  cases,  again,  the  clinical  trials  are  conducted  in  accordance  with  GCp  and  the  other  applicable  regulatory
requirements.

if we fail to comply with applicable foreign regulatory requirements, we may be subject to, among other things, fines,
suspension  of  clinical  trials,  suspension  or  withdrawal  of  regulatory  approvals,  product  recalls,  seizure  of  products,  operating
restrictions and criminal prosecution.

Manufacturing

our manufacturing strategy is to contract with third parties to manufacture the raw materials, our active pharmaceutical
ingredients,  or  api,  and  finished  dosage  form  for  clinical  and  commercial  uses.  We  currently  do  not  operate  manufacturing
facilities  for  clinical  or  commercial  production  of  JaKaFi,  iCluSiG,  pEmaZYrE  or  our  drug  candidates.  in  addition,  we
expect  for  the  foreseeable  future  to  continue  to  rely  on  third  parties  for  the  manufacture  of  commercial  supplies  of  the  raw
materials, api and finished drug product for any drugs that we successfully develop and are approved for commercial sale. in this
manner, we continue to build and maintain our supply chain and quality assurance resources.

Manufacturing of our Products

our supply chain for manufacturing raw materials, api and drug product ready for distribution and commercialization is
a multi-step international process. Establishing and managing the supply chain requires a significant financial commitment and
the creation and maintenance of numerous third-party contractual relationships.

We contract with third parties to manufacture JaKaFi, iCluSiG, pEmaZYrE and our drug candidates for clinical and
commercial  purposes.  our  collaborator  morphoSys  is  currently  responsible  for  sourcing  manufacturing  of  monJuvi.  third-
party manufacturers supply raw materials, and other third-party manufacturers convert these raw materials into api or convert the
api into final dosage form. For most of our drug candidates, once our raw materials are produced, we rely on one third-party to
manufacture the api, another to make finished drug product and a third to package and label the finished product. For ruxolitinib
phosphate,  the  api  for  JaKaFi,  we  have  two  qualified  third-party  contract  manufacturers  from  which  we  can  source  drug
substance. the manufacturing of ponatinib, the api for iCluSiG, is the sole responsibility of takeda, the intellectual property
holder. We procure  api from takeda, which outsources  the api manufacturing  to a third party.  For pemigatinib,  the api for
pEmaZYrE, we have one qualified third-party contract manufacturer from which we can source drug substance.

We also rely on third-party contract manufacturers to tablet or capsulate all of our active pharmaceutical ingredients for
clinical and commercial uses. For JaKaFi and iCluSiG, we have two qualified third-party manufacturers from which we can
source  commercial  drug  product.    Secondary  packaging  of  iCluSiG  is  performed  by  a  qualified  third-party  manufacturer.
primary  packaged  product  for  iCluSiG  can  be  used  for  clinical  and  commercial  purposes.  For  pEmaZYrE,  we  have  one
qualified third-party manufacturer from which we can source commercial drug product.  

We may not be able to obtain sufficient quantities of any of our raw materials, drug candidates, api, or finished goods if
our designated manufacturers do not have the capacity or capability to manufacture our products according to our schedule and
specifications.  if  any  of  these  single  source  suppliers  were  to  become  unable  or  unwilling  to  supply  us  with  api  or  finished
product  that  complies  with  applicable  regulatory  requirements,  we  could  incur  significant  delays  in  our  clinical  trials  or
interruption of commercial supply which could have a material adverse effect on our business. Similar risks apply to our supply
of monJuvi under our collaboration with morphoSys.

We  have  established  a  quality  assurance  program  intended  to  ensure  that  our  third-party  manufacturers  and  service
providers  produce  materials  and  provide  services,  as  applicable,  in  accordance  with  the  FDa  and  Ema’s  current  Good
manufacturing  practices  and  other  applicable  regulations.  our  quality  assurance  program  extends  to  our  licensed  facilities  that
oversee the manufacturing and distribution activities.

For our future products, we intend to continue to establish third-party suppliers to manufacture sufficient quantities of
our  drug  candidates  to  undertake  clinical  trials  and  to  manufacture  sufficient  quantities  of  any  product  that  is  approved  for
commercial sale. if we are unable to contract for large scale manufacturing with third parties on acceptable terms for our future
products  or  develop  manufacturing  capabilities  internally,  our  ability  to  conduct  large  scale  clinical  trials  and  meet  customer
demand for commercial products will be adversely affected.

in July 2018, we purchased land located in Yverdon, Switzerland for construction of a large molecule production facility
to manufacture biologic drug substances for our drug candidates. Construction activity commenced in July 2018 and we currently
expect the facility will be operational in the second half of 2021.

Third-party Manufacturers

our  third-party  manufacturers  are  independent  entities,  under  contract  with  us,  who  are  subject  to  their  own  unique
operational  and  financial  risks  which  are  out  of  our  control.  if  we  or  any  of  our  third-party  manufacturers  fail  to  perform  as
required,  this  could  impair  our  ability  to  deliver  our  products  on  a  timely  basis  or  cause  delays  in  our  clinical  trials  and
applications  for  regulatory  approval.  to  the  extent  these  risks  materialize  and  affect  their  performance  obligations  to  us,  our
financial results may be adversely affected.

For  products  manufactured  by  our  third-party  manufacturers,  we  have  licensed  the  necessary  aspects  of  this
manufacturing  technology  that  we  believe  is  proprietary  to  us  to  enable  them  to  manufacture  the  products  for  us.  We  have
agreements  with  these  third-party  manufacturers  that  are  intended  to  restrict  these  manufacturers  from  using  or  revealing  our
technology, but we cannot be certain that these third-party manufacturers will comply with these restrictions.

While  we  believe  there  are  multiple  third  parties  capable  of  providing  most  of  the  materials  and  services  we  need  in
order  to  manufacture  api  and  distribute  finished  goods,  and  that  supply  of  materials  that  cannot  be  second  sourced  can  be
managed with inventory planning, there is always a risk that we may underestimate demand, and that our manufacturing capacity
through third-party manufacturers may not be sufficient. in addition, because of the significant lead times involved in our supply
chain for ruxolitinib phosphate, we may have less flexibility to adjust our supply in response to changes in demand than if we had
shorter lead times.  our strategy is to maintain 24 months of safety stock of api to be able to respond to changes in demand to
provide on-time supply of drug product as well as at least 6 months of semi-finished goods inventory.

Access to Supplies and Materials

our  third-party  manufacturers  need  access  to  certain  supplies  and  products  to  manufacture  JaKaFi,  iCluSiG,
pEmaZYrE and our drug candidates. if delivery of material from their suppliers were interrupted for any reason or if they are
unable  to  purchase  sufficient  quantities  of  raw  materials  used  to  manufacture  JaKaFi,  iCluSiG,  pEmaZYrE  and  our  drug
candidates,  they  may  be  unable  to  ship  JaKaFi,  iCluSiG  and  pEmaZYrE  for  commercial  supply  or  to  supply  our  drug
candidates in development for clinical trials. For example, currently raw materials used to manufacture ruxolitinib phosphate, the
api  in  JaKaFi,  are  supplied  by  Chinese-based  companies.  as  a  result,  an  international  trade  dispute  between  China  and  the
united  States  or  any  other  actions  by  the  Chinese  government  that  would  limit  or  prevent  Chinese  companies  from  supplying
these  materials  would  adversely  affect  our  ability  to  manufacture  and  supply  our  products  to  meet  market  needs  and  have  a
material and adverse effect on our operating results.

Human Capital

our  human  capital  management  philosophy  is  committed  to  promoting  an  environment  where  our  colleagues  are
fulfilled and valued. We promote a company culture based on scientific excellence as we seek to create new treatments; we are
creative  in  our  development  strategies;  and  we  seek  positive  collaboration  with  each  other.  Working  collaboratively  is  of  the
utmost  importance  as  we  aim  to  change  the  treatment  landscape  for  patients  with  cancer  and  inflammatory  and  autoimmune
diseases.  it  is  our  goal  to  conduct  business  in  a  manner  that  does  not  compromise  the  health  of  people  nor  the  state  of  the
environment. it is our policy to comply with all applicable environmental health and safety (EhS) regulatory requirements and
seek to continually improve our EhS management systems. a strong safety culture is a fundamental part of how we work, and
our philosophy is that everyone at incyte has a responsibility to create and maintain a safe and healthy workplace with a goal to
reduce risk and prevent injuries.

We appreciate one another’s differences and strengths and are proud to be an Equal opportunity Employer. We value
diversity  of  backgrounds  and  perspectives  and  our  policy  is  that  we  do  not  discriminate  based  on  race,  religious  creed,  color,
national origin, ancestry, physical disability, mental disability, medical condition, genetic information, marital status, sex, gender,
gender  identity,  gender  expression,  age,  military  and  veteran  status,  sexual  orientation  or  any  other  protected  characteristic  as
established by federal, state or local laws. Further, we have policies in place that prohibit harassment of all kinds. at incyte, we
prohibit retaliation in all forms and are committed to encouraging a culture where employees can freely ask questions and raise
concerns. our management team makes themselves available to all employees and quarterly global town hall events allow for
open question and answer dialogue.

We  believe  that  creative  solutions  are  best  achieved  by  diverse  teams  working  together,  and  inclusion  is  therefore
essential  to incyte. Diversity of thoughts, backgrounds, perceptions and ideas help us create  the medical  solutions that patients
require, and represent the lifeblood of organizations such as ours. We have recently formed an inclusion Committee, which is co-
chaired by our Chief Executive officer and our head of human resources, to bring forth actionable plans across multiple focus
areas. We have expanded our recruitment searches to include organizations and websites dedicated to Black candidates. We have
also partnered with Jopwell, to aid connections with Black and other underrepresented candidates for non-science jobs and we are
participating in the reputable Scientific mentoring & Diversity program (SmDp) mentoring program that pairs primarily Black
and Brown students, who are post baccalaureate and graduate students with mentors who work at biopharmaceutical companies.
We additionally post all of our open positions on the historically Black Colleges and universities career pages.  

We  offer  what we  believe  is a  competitive  compensation  package,  which  allows  100% of  global  incyte  employees  to
participate in our annual incentive compensation plan as well as annual equity-based grants. We seek to ensure our compensation
package  remains  competitive  by  benchmarking  against  our  peers  several  times  annually  as  well  as  conducting  twice  per  year
compensation  reviews  to  confirm  that  our  employees  are  being  compensated  fairly,  equitably  and  in  accordance  with  our  pay
structures  and job levels.  in addition,  we offer  what we believe  is a competitive  benefits  package, which includes an option to
participate in our Employee Stock purchase plan for both full-time and part-time employees working at least 20 hours per week.
We believe that our health insurance coverage is industry-leading, as it provides 100% coverage for full-time employees and is
95%  subsidized  for  part-time  employees  working  at  least  20  hours  per  week  in  the  united  States.  Beyond  compensation  and
benefits, we are committed to supporting our colleagues in their professional development. opportunities for growth are provided
through challenging job assignments, performance management and training opportunities. Globally, all full-time employees are
eligible for tuition reimbursement. We believe these professional opportunities enhance our colleagues’ skills, career aspirations
and job satisfaction as well as provide personal enrichment.

as of December 31, 2020, we had 1,773 employees, including 930 in research and development, 161 in medical affairs,
438 in sales and marketing and 244 in operations support, finance and administrative positions. Geographically, 1,381 employees
were based in the united States and Canada, 356 employees were based in Europe and 36 employees were based in asia. none of
our employees are covered by collective bargaining agreements, and management considers relations with our employees to be
good.

Item 1A.  Risk Factors

RISKS RELATING TO COMMERCIALIZATION OF OUR PRODUCTS

We depend heavily on our lead product, JAKAFI (ruxolitinib), which is marketed as JAKAVI outside the United States. If we
are unable to maintain revenues from JAKAFI or those revenues decrease, our business may be materially harmed.

JaKaFi is our first product marketed by us that is approved for sale in the united States. JaKaFi was approved by the
u.S.  Food  and  Drug  administration,  or  FDa,  in  november  2011  for  the  treatment  of  patients  with  intermediate  or  high-risk
myelofibrosis, in December 2014 for the treatment of patients with polycythemia vera who have had an inadequate response to or
are intolerant of hydroxyurea, which we refer to as uncontrolled polycythemia vera, and in may 2019 for the treatment of steroid-
refractory acute graft-versus-host disease in adult and pediatric patients 12 years and older. although we have received regulatory
approval for these indications, such approval does not guarantee future revenues. While we also sell iCluSiG in the European
union, or Eu, and other countries for the treatment of certain types

33

table of Contents

of leukemia, pEmaZYrE in the united States for the treatment of specified cholangiocarcinoma indications, and monJuvi in
the united States for the treatment of certain lymphoma indications and our exclusive licensees sell olumiant (baricitinib) for
the treatment  of specified rheumatoid  arthritis and atopic dermatitis  indications and taBrECta for the treatment  of a certain
type of non small-cell lung cancer, we anticipate that JaKaFi product sales will continue to contribute a significant percentage of
our total revenues over the next several years.

the  commercial  success  of  JaKaFi  and  our  ability  to  maintain  and  continue  to  increase  revenues  from  the  sale  of

JaKaFi will depend on a number of factors, including:

●

the  number  of  patients  with  intermediate  or  high-risk  myelofibrosis,  uncontrolled  polycythemia  vera  or  steroid-
refractory acute graft-versus-host disease who are diagnosed with the diseases and the number of such patients that
may be treated with JaKaFi;

●

the acceptance of JaKaFi by patients and the healthcare community;

● whether  physicians,  patients  and  healthcare  payors  view  JaKaFi  as  therapeutically  effective  and  safe  relative  to

cost and any alternative therapies;

●

●

●

●

●

●

●

the ability to obtain and maintain sufficient coverage or reimbursement by third-party payors and pricing;

the ability of our third-party manufacturers to manufacture JaKaFi in sufficient quantities that meet all applicable
quality standards;

the ability of our company and our third-party providers to provide marketing and distribution support for JaKaFi;

the  effects  of  the  CoviD-19  pandemic,  any  associated  quarantine,  travel  restriction,  stay-at-home  or  shutdown
orders,  guidelines  or  practices,  and  any  disruption  in  our  supply  chain  for  JaKaFi  on  our  ability  to  provide
marketing and distribution support for JaKaFi, our ability to produce sufficient quantities of JaKaFi that meet all
applicable  quality  standards,  patient  demand  (including  new patient  prescriptions)  and other  risks  detailed  further
below under “—other risks relating to our Business—public health epidemics, such as the CoviD-19 pandemic,
could adversely affect our business, results of operations, and financial condition”;

the label and promotional claims allowed by the FDa;

the maintenance of regulatory approval for the approved indications in the united States; and

our  ability  to  develop,  obtain  regulatory  approval  for  and  commercialize  ruxolitinib  in  the  united  States  for
additional indications.

if we are not able to maintain revenues from JaKaFi in the united States, or our revenues from JaKaFi decrease, our
business  may  be  materially  harmed  and  we  may  need  to  delay  other  drug  discovery,  development  and  commercialization
initiatives or even significantly curtail operations, and our ability to license or acquire new products to diversify our revenue base
could be limited.

in addition, our receipt of royalties under our collaboration agreements with novartis for sales of JaKavi outside the
united  States  and  taBrECta  globally  and  with  Eli  lilly  and  Company  for  worldwide  sales  of  olumiant  will  depend  on
factors  similar  to  those  listed  above,  with  similar  regulatory,  pricing  and  reimbursement  issues  driven  by applicable  regulatory
authorities and governmental and third-party payors affecting jurisdictions outside the united States.

34

table of Contents

If  we  are  unable  to  obtain,  or  maintain  at  anticipated  levels,  reimbursement  for  our  products  from  government  health
administration authorities, private health insurers and other organizations, our pricing may be affected or our product sales,
results of operations or financial condition could be harmed.

We may not be able to sell our products on a profitable basis or our profitability may be reduced if we are required to
sell  our  products  at  lower  than  anticipated  prices  or  reimbursement  is  unavailable  or  limited  in  scope  or  amount.  the  costs  of
JaKaFi, iCluSiG, pEmaZYrE and monJuvi are not insignificant and almost all patients will require some form of third-
party  coverage  to  afford  their  cost.  our  future  revenues  and  profitability  will  be  adversely  affected  if  we  cannot  depend  on
government and other third-party payors to defray the cost of our products to the patient. reimbursement systems in international
markets  vary  significantly  by  country  and  by  region,  and  reimbursement  approvals  must  be  obtained  on  a  country-by-country
basis. reimbursement in the Eu must be negotiated on a country-by-country basis and in many countries the product cannot be
commercially launched until reimbursement is approved. the timing to complete the negotiation process in each country is highly
uncertain,  and  in  some  countries,  we  expect  that  it  may  exceed  12  months.    risks  related  to  pricing  and  reimbursement  are
described  below  under  “—other  risks  relating  to  our  Business—health  care  reform  measures  could  impact  the  pricing  and
profitability  of  pharmaceuticals,  and  adversely  affect  the  commercial  viability  of  our  or  our  collaborators’  products  and  drug
candidates. our ability to generate revenues will be diminished if we or our collaborators are unable to obtain an adequate level of
reimbursement from private insurers, government insurance programs or other third party payors of health care costs, which could
be affected by current and potential healthcare reform legislation, and diminished revenues will harm our operating results and
financial condition and could adversely affect our ability to conduct our research and development operations.” if government and
other third-party payors refuse to provide coverage and reimbursement with respect to our products, determine to provide a lower
level  of  coverage  and  reimbursement  than  anticipated,  reduce  previously  approved  levels  of  coverage  and  reimbursement,  or
delay  reimbursement  payments  due  to  budgetary  constraints  relating  to  the  CoviD-19  pandemic,  then  our  pricing  or
reimbursement  for  our  products  may  be  affected  and  our  product  sales,  results  of  operations  or  financial  condition  could  be
harmed.

 We depend upon a limited  number of specialty  pharmacies  and wholesalers for a significant portion of any revenues from
JAKAFI,  and  the  loss  of,  or  significant  reduction  in  sales  to,  any  one  of  these  specialty  pharmacies  or  wholesalers  could
adversely affect our operations and financial condition.

We sell JaKaFi primarily to specialty pharmacies and wholesalers. Specialty pharmacies dispense JaKaFi to patients
in fulfillment  of prescriptions  and wholesalers  sell  JaKaFi to hospitals  and physician  offices.  We do not promote  JaKaFi to
specialty  pharmacies  or  wholesalers,  and  they  do  not  set  or  determine  demand  for  JaKaFi.  our  ability  to  successfully
commercialize JaKaFi will depend, in part, on the extent to which we are able to provide adequate distribution of JaKaFi to
patients.  although  we  have  contracted  with  a  number  of  specialty  pharmacies  and  wholesalers,  they  are  expected  generally  to
carry a very limited inventory and may be reluctant to be part of our distribution network in the future if demand for the product
does not increase. Further, it is possible that these specialty pharmacies and wholesalers could decide to change their policies or
fees, or both, at some time in the future. this could result in their refusal to carry smaller volume products such as JaKaFi, or
lower margins or the need to find alternative methods of distributing our product. although we believe we can find alternative
channels to distribute  JaKaFi on relatively  short notice, our revenue during that period of time may suffer and we may incur
additional costs to replace any such specialty pharmacy or wholesaler. the loss of any large specialty pharmacy or wholesaler as
part of our distribution network, a significant reduction in sales we make to specialty pharmacies or wholesalers, or any failure to
pay  for  the  products  we  have  shipped  to  them  could  materially  and  adversely  affect  our  results  of  operations  and  financial
condition.

If we are unable to establish and maintain effective sales, marketing and distribution capabilities, or to enter into agreements
with third parties to do so, we will not be able to successfully commercialize our products.

We have established commercial capabilities in the united States and outside of the united States, but cannot guarantee
that  we  will  be  able  to  enter  into  and  maintain  any  marketing,  distribution  or  third-party  logistics  agreements  with  third-party
providers on acceptable terms, if at all. We may not be able to correctly judge the size and experience of the sales and marketing
force  and  the  scale  of  distribution  capabilities  necessary  to  successfully  market  and  sell  any  new  products.  Establishing  and
maintaining  sales,  marketing  and  distribution  capabilities  are  expensive  and  time-consuming.  Competition  for  personnel  with
experience in sales and marketing can be high. our expenses associated with building and

35

table of Contents

maintaining  the  sales  force  and  distribution  capabilities  may  be  disproportional  compared  to  the  revenues  we  may  be  able  to
generate on sales of our products.

to the extent that we are able to obtain marketing approval for ruxolitinib cream  for dermatology indications such as
atopic  dermatitis  and  vitiligo,  we  will  have  to  establish  and  maintain  sales,  marketing  and  distribution  capabilities  that  will
generally be separate from our existing capabilities for oncology indications, and we have no prior experience in commercializing
products  for  dermatology  indications.  Successful  commercialization  of  our  drug  candidates  for  dermatology  indications,  if
approved,  will  require  us  to  establish  new  physician  and  payor  relationships,  reimbursement  strategies  and  governmental
interactions. our inability to commercialize successfully products in indications outside of oncology could harm our business and
operating results.

If we fail to comply with applicable laws and regulations, we could lose our approval to market our products or be subject to
other governmental enforcement activity.

We cannot guarantee that we will be able to maintain regulatory approval to market our products in the jurisdictions in
which they are currently marketed. if we do not maintain our regulatory approval to market our products, in particular JaKaFi,
our results of operations will be materially harmed. We and our collaborators, third-party manufacturers and suppliers are subject
to rigorous and extensive regulation by the FDa and other federal and state agencies as well as foreign governmental agencies.
these  regulations  continue  to  apply  after  product  marketing  approval,  and  cover,  among  other  things,  testing,  manufacturing,
quality control and assurance, labeling, advertising, promotion, risk mitigation, and adverse event reporting requirements.

the commercialization of our products is subject to post-regulatory approval product surveillance, and our products may
have to be withdrawn from the market or subject to restrictions if previously unknown problems occur. regulatory agencies may
also  require  additional  clinical  trials  or  testing  for  our  products,  and  our  products  may  be  recalled  or  may  be  subject  to
reformulation, additional studies, changes in labeling, warnings to the public and negative publicity.  For example, from late 2013
through  2014,  iCluSiG  was  subject  to  review  by  the  European  medicines  agency,  or  Ema,  of  the  benefits  and  risks  of
iCluSiG  to  better  understand  the  nature,  frequency  and  severity  of  events  obstructing  the  arteries  or  veins,  the  potential
mechanism  that  leads  to  these  side  effects  and  whether  there  needed  to  be  a  revision  in  the  dosing  recommendation,  patient
monitoring and a risk management plan for iCluSiG. this review was completed in January 2015, with additional warnings in
the product information but without any change in the approved indications.  the Ema could take additional actions in the future
that reduce the commercial potential of iCluSiG.

Failure to comply with the laws and regulations administered by the FDa or other agencies could result in:

administrative and judicial sanctions, including warning letters;

the occurrence of any such event may have a material adverse effect on our business.

If the use of our products harms patients, or is perceived to harm patients even when such harm is unrelated to our products,
our  regulatory  approvals  could  be  revoked  or  otherwise  negatively  impacted  or  we  could  be  subject  to  costly  and  damaging
product liability claims.

the testing of JaKaFi, iCluSiG, pEmaZYrE and monJuvi, the manufacturing, marketing and sale of JaKaFi and
pEmaZYrE and the marketing and sale of iCluSiG and monJuvi expose us to product liability and other risks. Side effects
and other problems experienced by patients from the use of our products could:

●

●

●

●

lessen the frequency with which physicians decide to prescribe our products;

encourage  physicians  to  stop  prescribing  our  products  to  their  patients  who  previously  had  been  prescribed  our
products;

cause serious harm to patients that may give rise to product liability claims against us; and

result in our need to withdraw or recall our products from the marketplace.

if our products are used by a wide patient population, new risks and side effects may be discovered, the rate of known

risks or side effects may increase, and risks previously viewed as less significant could be determined to be significant.

previously unknown risks and adverse effects of our products may also be discovered in connection with unapproved, or
off-label, uses of our products. We are prohibited by law from promoting or in any way supporting or encouraging the promotion
of our products for off-label uses, but physicians are permitted to use products for off-label purposes. in addition, we are studying
and  expect  to  continue  to  study  JaKaFi  in  diseases  for  potential  additional  indications  in  controlled  clinical  settings,  and
independent investigators are doing so as well. in the event of any new risks or adverse effects discovered as new patients are
treated  for  intermediate  or  high-risk  myelofibrosis,  uncontrolled  polycythemia  vera  or  acute  graft-versus-host  disease  and  as
JaKaFi is studied in or used by patients for off-label indications, regulatory authorities may delay or revoke their approvals, we
may be required to conduct additional clinical trials, make changes in labeling of JaKaFi, reformulate JaKaFi or make changes
and obtain new approvals. We may also experience a significant drop in the sales of JaKaFi, experience harm to our reputation
and  the  reputation  of  JaKaFi  in  the  marketplace  or  become  subject  to  lawsuits,  including  class  actions.  any  of  these  results
could decrease or prevent sales of JaKaFi or substantially increase the costs and expenses of commercializing JaKaFi. Similar
results could occur with respect to our commercialization of iCluSiG, pEmaZYrE and monJuvi.

patients who have been enrolled in our clinical trials or who may use our products in the future often have severe and
advanced stages of disease and known as well as unknown significant pre-existing and potentially life-threatening  health risks.
During the course of treatment, patients may suffer adverse events, including death, for reasons that may or may not be related to
our products. Such events could subject us to costly litigation, require us to pay substantial amounts of money to injured patients,
delay, negatively impact or end our opportunity to receive or maintain regulatory approval to market our products, or require us to
suspend or abandon our commercialization efforts. Even in a circumstance in which we do not believe that an adverse event is
related to our products, the investigation into the circumstance may be time consuming or inconclusive. these investigations may
interrupt  our  sales  efforts,  impact  and  limit  the  type  of  regulatory  approvals  our  products  receive  or  maintain,  or  delay  the
regulatory approval process in other countries.

Factors similar to those listed above also apply to our collaborator novartis for jurisdictions in which it has development
and commercialization rights, to iCluSiG for jurisdictions outside the united States, to our collaborator lilly for all jurisdictions
and to our collaborator innovent for pEmaZYrE in the jurisdictions in which it has development and commercialization rights.

If  we  market  our  products  in  a  manner  that  violates  various  laws  and  regulations,  we  may  be  subject  to  civil  or  criminal
penalties.

in addition to FDa and related regulatory requirements, we are subject to health care “fraud and abuse” laws, such as the
federal  False  Claims  act,  the  anti-kickback  provisions  of  the  federal  Social  Security  act,  and  other  state  and  federal  laws  and
regulations.  Federal  and  state  anti-kickback  laws  prohibit,  among  other  things,  knowingly  and  willfully  offering,  paying,
soliciting or receiving remuneration to induce, or in return for purchasing, leasing, ordering or arranging for the purchase, lease or
order of any health care item or service reimbursable under medicare, medicaid, or other federally- or state-financed health care
programs. Federal false claims laws prohibit 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.
pharmaceutical companies have been prosecuted under these laws for a variety of alleged promotional and marketing activities.

although  physicians  are  permitted,  based  on  their  medical  judgment,  to  prescribe  products  for  indications  other  than
those  approved  by  the  FDa,  manufacturers  are  prohibited  from  promoting  their  products  for  such  off-label  uses.  We  market
JaKaFi  for  intermediate  or  high-risk  myelofibrosis,  uncontrolled  polycythemia  vera  and  acute  graft-versus-host  disease  and
provide  promotional  materials  to  physicians  regarding  the  use  of  JaKaFi  for  these  indications.  although  we  believe  that  our
promotional materials for physicians do not constitute improper promotion of JaKaFi, the FDa or other agencies may disagree.
if  the  FDa  or  another  agency  determines  that  our  promotional  materials  or  other  activities  constitute  improper  promotion  of
JaKaFi,  it  could  request  that  we  modify  our  promotional  materials  or  other  activities  or  subject  us  to  regulatory  enforcement
actions,  including  the  issuance  of  a  warning  letter,  injunction,  seizure,  civil  fine  and  criminal  penalties.  it  is  also  possible  that
other federal, state or foreign enforcement authorities might take action if they believe that the alleged improper promotion led to
the  submission  and  payment  of  claims  for  an  unapproved  use,  which  could  result  in  significant  fines  or  penalties  under  other
statutory authorities, such as laws prohibiting false claims for reimbursement. Even if it is later determined we are not in violation
of  these  laws,  we  may  be  faced  with  negative  publicity,  incur  significant  expenses  defending  our  position  and  have  to  divert
significant  management  resources  from  other  matters.  Similar  risks  exist  for  our  marketing  of  pEmaZYrE  and  our  and  our
collaborator morphoSys’s marketing of monJuvi.

the European union and member countries, as well as governmental authorities in other countries, impose similar strict
restrictions on the promotion and marketing of drug products.  the off-label promotion of medicinal products is prohibited in the
Eu and in other territories, and the Eu also maintains strict controls on advertising and promotional materials. the promotion of
medicinal products that are not subject to a marketing authorization is also prohibited in the Eu. violations of the rules governing
the promotion of medicinal products in the Eu and in other territories could be penalized by administrative measures, fines and
imprisonment.

the majority of states also have statutes or regulations similar to the federal anti-kickback  law and false claims laws,
which apply to items and services reimbursed under medicaid and other state programs, or, in several states, apply regardless of
the  payor.  numerous  states  and  localities  have  enacted  or  are  considering  enacting  legislation  requiring  pharmaceutical
companies  to  establish  marketing  compliance  programs,  file  periodic  reports  or  make  periodic  public  disclosures  on  sales,
marketing, pricing, clinical trials, and other activities. additionally, as part of the patient protection and affordable Care act, the
federal  government  has  enacted  the  physician  payment  Sunshine  provisions.  the  Sunshine  provisions  and  similar  laws  and
regulations  in  other  jurisdictions  where  we  do  business  require  manufacturers  to  publicly  report  certain  payments  or  other
transfers of value made to physicians and teaching hospitals. many of these requirements are new and uncertain, and the penalties
for failure to comply with these requirements are unclear. nonetheless, if we are found not to be in full compliance with these
laws, we could face enforcement action and fines and other penalties, which could be significant in amount or result in exclusion
from  federal  healthcare  programs  such  as  medicare  and  medicaid.    any  action  initiated  against  us  for  violation  of  these  laws,
even if we successfully defend against it, could require the expenditure of significant resources and generate negative publicity,
which could harm our business and operating  results. See also “—other  risks relating to our Business—if  we fail  to comply
with the extensive legal and regulatory requirements affecting the health care industry, we could face increased costs, penalties
and a loss of business” below.

Competition for our products could harm our business and result in a decrease in our revenue.

present  and  potential  competitors  for  JaKaFi  could  include  major  pharmaceutical  and  biotechnology  companies,  as
well as specialty pharmaceutical firms.  For example, in august 2019, Celgene Corporation, now a subsidiary of Bristol-myers
Squibb Company, announced that the FDa had approved inrEBiC (fedratinib) for the treatment of myelofibrosis. See “—other
risks relating to our Business— We face significant competition for our drug discovery and development efforts, and if we do
not  compete  effectively,  our  commercial  opportunities  will  be  reduced  or  eliminated”  for  a  description  of  risks  relating  to  this
type  of  competition.    in  addition,  JaKaFi  could  face  competition  from  generic  products.    as  a  result  of  the  Drug  price
Competition and patent term restoration act of 1984, commonly known as the hatch-Waxman act, in the united States, generic
manufacturers may seek approval of a generic version of an innovative pharmaceutical by filing with the FDa an abbreviated
new Drug application, or anDa. the hatch-Waxman act provides significant incentives to generic manufacturers to challenge
u.S. patents on successful innovative pharmaceutical products.  in February 2016, we received a notice letter regarding an anDa
that requested approval to market a generic version of JaKaFi and purported to challenge patents covering ruxolitinib phosphate
and its use that expire in 2028. the notice letter does not challenge the ruxolitinib composition of matter patent, which expires in
December 2027.  to date, to our knowledge, the FDa has taken no action with respect to this anDa. Separately, in January 2018
the patent trial and appeal Board (ptaB) of united States patent and trademark office denied a petition challenging our patent
covering  deuterated  ruxolitinib  analogs  and  the  ptaB subsequently  denied  the  petitioner’s  request  for  rehearing  in  may  2018.
nevertheless, the petitioner still has the right separately to challenge the validity of our patent in federal court.  there can be no
assurance  that  our  patents  will  be  upheld  or  that  any  litigation  in  which  we  might  engage  with  any  such  generic  manufacturer
would be successful in protecting JaKaFi’s exclusivity.  the entry of a generic version of JaKaFi could result in a decrease in
JaKaFi sales and materially harm our business, operating results and financial condition.

iCluSiG  currently  competes  with  existing  therapies  that  are  approved  for  the  treatment  of  patients  with  chronic
myeloid leukemia, or Cml, who are resistant or intolerant to prior tyrosine kinase inhibitor, or tKi, therapies, on the basis of,
among other things, efficacy, cost, breadth of approved use and the safety and side-effect profile. in addition, generic versions of
imatinib  are  available  and,  while  we  currently  believe  that  generic  versions  of  imatinib  will  not  materially  impact  our
commercialization of iCluSiG, given iCluSiG’s various indication statements globally that are currently focused on resistant or
intolerant Cml, we cannot be certain how physicians, payors, patients, regulatory authorities and other market participants will
respond to the availability of generic versions of imatinib. 

monJuvi currently competes with existing therapies that are approved for the treatment of patients with diffuse large
B-cell  lymphoma  on  the  basis  of,  among  other  things,  efficacy,  cost,  breadth  of  approved  use  and  the  safety  and  side-effect
profile.  these  existing  therapies  are  offered  by  major  pharmaceutical  and  biotechnology  companies,  as  well  as  specialty
pharmaceutical firms. potential competitors for pEmaZYrE could include major pharmaceutical and biotechnology companies,
as well as specialty pharmaceutical firms.   

OTHER RISKS RELATING TO OUR BUSINESS

Public  health  epidemics,  such  as  the  COVID-19  Pandemic,  could  adversely  affect  our  business,  results  of  operations,  and
financial condition.

our global operations expose us to risks associated with public health epidemics, such as the CoviD-19 pandemic that
has spread globally.  the extent to which the CoviD-19 pandemic and the measures taken to limit CoviD-19’s spread impact
our operations and those of our suppliers, collaborators, service providers and healthcare organizations serving patients, as well as
demand  for  our  drug  products,  will  depend  on  future  developments,  which  are  highly  uncertain  and  cannot  be  predicted  with
confidence, including the duration of the outbreak and any future resurgence of the outbreak, additional or modified government
actions, including any further restrictions or reopening of local, state or national social or economic activity, new information that
may emerge concerning the severity of CoviD-19 and the actions taken to contain CoviD-19 or treat its impact, among others.

as a result of the CoviD-19 pandemic, we may experience disruptions that could severely impact our business, results

of operations and financial condition, including the following:

39

table of Contents

●

to protect the health of our employees and their families, and our communities, in accordance with – and in some cases
in advance or - direction from state and local government authorities, we currently have limited access to certain of our
facilities  and  instituted  additional  precautions  in  our  facilities  that  have  reopened,  and  a  significant  percentage  of  our
personnel continue to work remotely a significant portion of their time. in the event that governmental authorities were
to  modify  current  restrictions  or  re-establish  greater  restrictions,  our  employees  conducting  research  and  development
activities  may  not  be  able  to  access  our  laboratory  space,  and  our  research  and  development  activities  may  be
significantly  limited  or  curtailed,  possibly  for  an  extended  period  of  time.   these  research  and  development  activities
could include completing investigational new Drug (inD)/Clinical trial application (Cta)-enabling studies, our ability
to select future development candidates, and initiation of additional clinical trials for our development programs. having
a significant portion of our employees work from home can strain our information technology infrastructure, which may
affect our ability to operate effectively, may make us more susceptible to communications disruptions, and expose us to
greater cybersecurity risks.

● our sales and marketing activities, including our interactions with healthcare professionals, have been limited and made
more  difficult  by  the  work  from  home  orders  and  travel  restrictions.  in  addition,  demand  for  our  products  has  been
affected  by  decreases  in  new  patients,  which  we  believe  resulted  in  large  part  from  decreases  in  patient  visits  to
healthcare professionals and prioritization of hospital resources for the CoviD-19 pandemic, resulting in decreases in
disease screening and diagnosis. We cannot predict the effects on patient demand or future sales if there are prolonged
quarantines, work from home orders or travel restrictions.  

● our  clinical  trials  have  been  and  may  in  the  future  be  affected  by  delays  in  site  initiation,  patient  screening,  patient
enrollment,  and  monitoring  and  data  collection  as  a  result  of  prioritization  of  hospital  resources  for  the  CoviD-19
pandemic,  travel  restrictions,  and  the  inability  to  access  sites  for  initiation  and  monitoring.  in  addition,  some  patients
may be unable to comply with clinical trial protocols if quarantines or stay at home orders impede patient movement or
interrupt health services, we may be unable to obtain blood samples for testing, and we may not be able to provide the
trial drug candidate to patients.

● health  regulatory  agencies  globally  have  experienced  disruptions  in  their  operations  as  a  result  of  the  coronavirus
pandemic. the FDa and comparable foreign regulatory agencies may have slower response times or be under-resourced
to  continue  to  monitor  our  clinical  trials  and,  as  a  result,  review,  inspection,  and  other  timelines  may  be  materially
delayed.  if  any  of  these  disruptions  occur  or  continue  to  occur,  we  cannot  predict  how  long  they  may  last.  our  drug
candidate application reviews and potential approvals could be impacted or delayed by these disruptions, if they occur or
continue to occur.  

●

the  outbreak  and  measures  taken  to  limit  the  spread  of  the  outbreak,  especially  if  prolonged,  could  also  disrupt  our
supply chain or limit our ability to obtain sufficient materials for our drug products and product candidates, which could
adversely affect our revenues and clinical trial timelines. Currently, our supply chain for our drug products and product
candidates depends on operations by us and by other companies in multiple countries around the world, and the effects
of the CoviD-19 pandemic on any or all of these countries is uncertain and unpredictable  and potential disruption is
possible.  in  addition,  our  third-party  manufacturers  might  experience  capacity  constraints  and  delays  in  producing
materials for our drug products and product candidates if they are required, under the u.S. Defense production act or
similar governmental mandates, to prioritize production of raw materials, supplies, drugs or vaccines to address CoviD-
19. and, for JaKaFi, while our strategy is to maintain a 24 month stock of active pharmaceutical ingredient, or api,
inclusive of finished product, ruxolitinib phosphate might be used by us either to make JaKaFi or for ruxolitinib drug
candidates in clinical trials.

● any  deterioration  of  worldwide  credit  and  financial  markets  could  result  in  losses  on  our  holdings  of  cash  and
investments  due  to  failures  of  financial  institutions  and  other  parties,  and  interruptions  and  delays  in  our  ability  to
collect, or potential losses on, our accounts receivable.      

our  collaborators  could  be  affected  by  similar  factors  as  those  that  have  or  could  affect  our  business.  the  ultimate
impact of the CoviD-19 pandemic or a similar health epidemic is highly uncertain and subject to change.  We do not yet know
the  full  extent  of  potential  impacts  or  delays  on  our  or  our  collaborators’  businesses,  our  revenues,  including  milestone  and
royalty revenues from our collaborators, our and our collaborators’ clinical trials, healthcare systems or the

40

table of Contents

global economy as a whole.  however, these effects could have a material adverse impact on our business, results of operations,
and financial condition.

We may be unsuccessful in our efforts to discover and develop drug candidates and commercialize drug products.

our  long-term  success,  revenue  growth  and  diversification  of  revenues  depends  on  our  ability  to  obtain  regulatory
approval  for  new  drug  products  and  new  indications  for  our  existing  drug  products.    our  ability  to  discover  and  develop  drug
candidates and to commercialize additional drug products and indications will depend on our ability to:

●

●

●

●

●

●

●

●

●

●

●

●

●

●

hire and retain key employees;

identify high quality therapeutic targets;

identify potential drug candidates;

develop products internally or license drug candidates from others;

identify and enroll suitable human subjects, either in the united States or abroad, for our clinical trials;

complete laboratory testing;

commence, conduct and complete safe and effective clinical trials on humans;

obtain and maintain necessary intellectual property rights to our products;

obtain and maintain necessary regulatory approvals for our products, both in the united States and abroad;

enter into arrangements with third parties to provide services or to manufacture our products on our behalf;

deploy sales, marketing, distribution and manufacturing resources effectively or enter into arrangements with third
parties to provide these functions in compliance with all applicable laws;

obtain appropriate coverage and reimbursement levels for the cost of our products from governmental authorities,
private health insurers and other third-party payors;

lease facilities at reasonable rates to support our growth; and

enter into arrangements with third parties to license and commercialize our products.

We may not be successful in discovering, developing, or commercializing additional drug products or our existing drug
products in new indications. Discovery and development of drug candidates are expensive, uncertain and time-consuming, and we
do not know if our efforts will lead to discovery of any drug candidates that can be successfully developed and marketed. of the
compounds or biologics  that  we identify  as potential  drug products  or that  we may in-license  from  other  companies,  including
potential products for which we are conducting clinical trials, only a few, if any, are likely to lead to successful drug development
programs and commercialized drug products.

We  depend  heavily  on  the  success  of  our  most  advanced  drug  candidates.  We  and  our  collaborators  might  not  be  able  to
commercialize any of our or their drug candidates successfully, and we may spend significant time and money attempting to
do so.

We  have  invested  significant  resources  in  the  development  of  our  most  advanced  drug  candidates.  We  and  our
collaborator  morphoSys  have  submitted  a  European  marketing  authorization  application  with  the  Ema  for  tafasitamab  in
combination with lenalidomide for the treatment of patients with a specified type of lymphoma. ruxolitinib is in phase

41

table of Contents

iii clinical trials for the treatment of patients with steroid-refractory graft-versus-host disease and patients with CoviD-19 and is
in  other  clinical  trials.  ruxolitinib  cream  is  in  phase  iii  clinical  trials  for  the  treatment  of  patients  with  atopic  dermatitis  and
vitiligo. itacitinib is in phase iii clinical trials for the treatment  of patients with chronic graft-versus-host  disease.  Further, we
have a number of drug candidates in phase i and phase ii clinical trials. our ability to generate product revenues will depend on
the successful development and eventual commercialization of our most advanced drug candidates. We, or our collaborators or
licensees, may decide to discontinue development of any or all of our drug candidates at any time for commercial, scientific or
other reasons.  For example:  in early  2016, we decided to discontinue  the clinical  trials  of ruxolitinib  in pancreatic  cancer  and
solid  tumors  and  itacitinib  in  pancreatic  cancer;  and,  in  april  2018,  we  along  with  merck  stopped  the  ECho-301  study  with
epacadostat,  and  we  also  significantly  downsized  the  epacadostat  development  program.  in  addition,  in  January  2020  we
announced that itacitinib did not meet the primary endpoint in the phase iii clinical trial for the treatment of patients with acute
graft-versus-host disease.  if a product is developed but not approved or marketed, we may have spent significant amounts of time
and money on it, which could adversely affect our operating results and financial condition as well as our business plans.

If we or our collaborators are unable to obtain regulatory approval for our drug candidates in the United States and foreign
jurisdictions, we or our collaborators will not be permitted to commercialize products resulting from our research.

in order to commercialize  drug products in the united States, drug candidates will have to obtain regulatory approval
from  the  FDa.  Satisfaction  of  regulatory  requirements  typically  takes  many  years.  to  obtain  regulatory  approval,  we  or  our
collaborators, as the case may be, must first show that our or our collaborators’ drug candidates are safe and effective for target
indications  through  preclinical  testing  (animal  testing)  and  clinical  trials  (human  testing).  preclinical  testing  and  clinical
development  are  long,  expensive  and  uncertain  processes,  and  we  do  not  know  whether  the  FDa  will  allow  us  or  our
collaborators to undertake clinical trials of any drug candidates in addition to our or our collaborators’ compounds currently in
clinical trials. if regulatory approval of a product is granted, this approval will be limited to those disease states and conditions for
which the product is demonstrated through clinical trials to be safe and effective.

Completion  of clinical  trials  may  take  several  years  and failure  may  occur  at  any stage  of  testing.  the  length  of  time
required varies substantially according to the type, complexity, novelty and intended use of the drug candidate. interim results of
a preclinical test or clinical trial do not necessarily predict final results, and acceptable results in early clinical trials may not be
repeated  in  later  clinical  trials.  For  example,  a  drug  candidate  that  is  successful  at  the  preclinical  level  may  cause  harmful  or
dangerous  side  effects  when  tested  at  the  clinical  level.  our  rate  of  commencement  and  completion  of  clinical  trials  may  be
delayed, and existing clinical trials with our or our collaborators’ drug candidates may be stopped, due to many potential factors,
including:

●

●

●

●

●

●

●

the high degree of risk and uncertainty associated with drug development;

our inability to formulate or manufacture sufficient quantities of materials for use in clinical trials;

variability in the number and types of patients available for each study;

difficulty in maintaining contact with patients after treatment, resulting in incomplete data;

unforeseen safety issues or side effects;

poor or unanticipated effectiveness of drug candidates during the clinical trials; or

government or regulatory delays.

Data obtained from clinical trials are susceptible to varying interpretation, which may delay, limit or prevent regulatory
approval.  many  companies  in  the  pharmaceutical  and  biopharmaceutical  industry,  including  our  company,  have  suffered
significant  setbacks  in  advanced  clinical  trials,  even  after  achieving  promising  results  in  earlier  clinical  trials.  in  addition,
regulatory authorities may refuse or delay approval as a result of other factors, such as changes in regulatory

42

table of Contents

policy during the period of product development and regulatory agency review. For example, the FDa has in the past required,
and could in the future require, that we or our collaborators conduct additional trials of any of our drug candidates, which would
result in delays. in april 2017, we and our collaborator lilly announced that the FDa had issued a complete response letter for
the  new  Drug  application,  or  nDa,  of  olumiant  as  a  once-daily  oral  medication  for  the  treatment  of  moderate-to-severe
rheumatoid arthritis. the letter indicated that additional clinical data were needed to determine the most appropriate doses and to
further characterize safety concerns across treatment arms. in June 2018, after a resubmission of the nDa, the FDa approved the
2mg dose of olumiant for the treatment of adults with moderately-to-severely active rheumatoid arthritis who have had an
inadequate response to one or more tumor necrosis factor inhibitor therapies.  the FDa did not at that time approve any higher
dose of olumiant and required a warning label in connection with its approval.

Compounds or biologics  developed  by us or with  or by  our  collaborators  and  licensees  may  not  prove to  be safe  and
effective in clinical trials and may not meet all of the applicable regulatory requirements needed to receive marketing approval.
For example,  in  January  2016,  a  phase  ii  trial  that  was evaluating  ruxolitinib  in  combination  with  regorafenib  in  patients  with
relapsed  or  refractory  metastatic  colorectal  cancer  and  high  C-reactive  protein  was  stopped  early  after  a  planned  analysis  of
interim  efficacy  data  determined  that  the  likelihood  of  the  trial  meeting  its  efficacy  endpoint  was  insufficient.    in  addition,  in
February 2016, we made a decision to discontinue our JanuS 1 study, our JanuS 2 study, our other studies of ruxolitinib in
colorectal, breast and lung cancer, and our study of inCB39110 in pancreatic cancer after a planned analysis of interim efficacy
data  of  JanuS  1  demonstrated  that  ruxolitinib  plus  capecitabine  did  not  show  a  sufficient  level  of  efficacy  to  warrant
continuation.  also,  in  april  2018,  we  along  with  merck  announced  that  the  ECho-301  study  had  been  stopped  and  we  also
significantly downsized the epacadostat development program and in January 2020 we stopped our phase iii trial of itacitinib for
the treatment of acute graft-versus-host-disease. if clinical trials of any of our or our collaborators’ compounds or biologics are
stopped for safety, efficacy or other reasons or fail to meet their respective endpoints, our overall development plans, business,
prospects, expected operating results and financial condition could be materially harmed and the value of our company could be
negatively affected.  

Even  if  any  of  our  applications  receives  an  FDa  priority  review  designation  (including  based  on  a  priority  review
voucher,  one  of  which  we  recently  acquired  and  used  in  connection  with  our  submission  seeking  FDa  approval  of  ruxolitinib
cream for atopic dermatitis), this designation may not result in faster review or approval for our product candidate compared to
product  candidates  considered  for  approval  under  conventional  FDa  procedures  and,  in  any  event,  does  not  assure  ultimate
approval of our product candidate by FDa.

outside  the  united  States,  our  and  our  collaborators’  ability  to  market  a  product  is  contingent  upon  receiving  a
marketing authorization from the appropriate regulatory authorities. this foreign regulatory approval process typically includes
all of the risks associated with the FDa approval process described above and may also include additional risks. the requirements
governing the conduct of clinical trials, product licensing, pricing and reimbursement vary greatly from country to country and
may require us to perform additional testing and expend additional resources. approval by the FDa does not ensure approval by
regulatory authorities in other countries, and approval by one foreign regulatory authority does not ensure approval by regulatory
authorities in other countries or by the FDa.

Health  care  reform  measures  could  impact  the  pricing  and  profitability  of  pharmaceuticals,  and  adversely  affect  the
commercial  viability  of  our  or  our  collaborators’  products  and  drug  candidates.  Our  ability  to  generate  revenues  will  be
diminished  if  we  or  our  collaborators  are  unable  to  obtain  an  adequate  level  of  reimbursement  from  private  insurers,
government  insurance  programs  or  other  third-party  payors  of  health  care  costs,  which  could  be  affected  by  current  and
potential healthcare reform legislation, and diminished revenues will harm our operating results and financial condition and
could adversely affect our ability to conduct our research and development operations.

our ability to commercialize our current and any future approved products successfully will depend in part on the prices
we  are  able  to  charge  for  our  approved  products  and  the  extent  to  which  adequate  reimbursement  levels  for  the  cost  of  our
products  and  related  treatment  are  obtained  from  third-party  payors,  such  as  private  insurers,  government  insurance  programs,
including medicare and medicaid, health maintenance organizations  (hmos) and other health care related organizations in the
united States and abroad.

in recent years, through legislative and regulatory actions and executive orders, the u.S. federal government has made
substantial  changes  to  various  payment  systems  under  the  medicare  and  other  federal  health  care  programs.  Comprehensive
reforms  to  the  u.S.  healthcare  system  were  enacted,  including  changes  to  the  methods  for,  and  amounts  of,  medicare
reimbursement.  While  there  is  currently  significant  uncertainty  regarding  the  implementation  of  some  of  these  reforms  or  the
scope of amended or additional reforms, the implementation of reforms could significantly reduce payments from medicare and
medicaid. reforms or other changes to these payment systems may change the availability, methods and rates of reimbursements
from  medicare,  private  insurers  and  other  third-party  payors  for  our  current  and  any  future  approved  products.  Some  of  these
changes  and  proposed  changes  could  result  in  reduced  reimbursement  rates  or  in  eliminating  dual  sources  of  payment,  which
could reduce the price that we or any of our collaborators or licensees receive for any products in the future, and which would
adversely affect our business strategy, operations and financial results.

in addition, there has been an increasing legislative and enforcement interest in the united States with respect to drug
pricing practices. this has resulted in several recent federal and state proposals, including executive orders issued by the trump
administration in July 2020, to regulate prices of pharmaceutical products and other health care reforms, any of which could limit
the prices that we can charge for our products and may further limit the commercial viability of our products and drug candidates.
Specifically, there have been several federal congressional inquiries and proposed and enacted federal and state legislation and the
July  2020  executive  orders  designed  to,  among  other  things,  bring  more  transparency  to  drug  pricing,  reduce  the  cost  of
prescription  drugs  under  medicare,  reform  government  program  reimbursement  methodologies  for  prescription  drugs,  allow
importation of drugs into the united States from other countries and limit allowable prices for drugs to a function of an average
international reference price that may be substantially lower than what we currently or would otherwise charge. in certain foreign
markets, pricing or profitability of prescription pharmaceuticals is subject to government control. We expect that the health care
reform measures that have been adopted in the united States and in foreign markets, and further reforms that may be adopted in
the future, could result in more rigorous coverage criteria and additional downward pressure on the prices that we may receive for
our  approved  products.  if  reimbursement  for  our  products  is  unavailable  or  limited  in  scope  or  amount,  or  if  pricing  is  set  at
unsatisfactory levels, our business could be materially harmed, including by our revenue potentially being materially adversely
affected and our research and development efforts potentially being materially curtailed or, in some cases, ceasing. there may be
future  changes  that  result  in  reductions  in  current  prices,  coverage  and  reimbursement  levels  for  our  current  or  any  future
approved products, and we cannot predict the scope of any future changes or the impact that those changes would have on our
operations.

the  consequences  of  the  CoviD-19  pandemic,  including  the  economic  effect  on  government  budgets  in  the  united
States and elsewhere, may accelerate any of the healthcare reform efforts described above or result in future reform efforts, any of
which could have adverse effects on our business, including higher costs for us, lower reimbursement rates for our products and
lower demand for our products.

if third parties institute high co-payment amounts or other benefit limits for our products, the demand for our products
and,  accordingly,  our  revenues  and  results  of  operations,  could  be  adversely  affected.  our  patient  assistance  programs  have
provided support for non-profit organizations that provide financial assistance to eligible patients or in some cases have provided
our  products  without  charge  to  patients  who  have  no  or  limited  insurance  coverage  through  these  charitable  organizations.
 Substantial  support  in  this  manner  could  harm  our  profitability  in  the  future.  Further,  those  organizations’  ability  to  provide
assistance to patients is dependent on funding from external sources, and we cannot guarantee that such funding will be provided
at adequate levels, or at all.  

Further, if we become the subject of any governmental or other regulatory hearing or investigation with respect to the
pricing of our products or other business practices, we could incur significant expenses and could be distracted from the operation
of our business and execution of our business strategy. any such hearing or investigation could also result in significant negative
publicity and harm to our reputation, reduced market acceptance and demand, which could adversely affect our financial results
and growth prospects.

third-party  payors  are  increasingly  challenging  the  prices  charged  for  medical  products  and  services.  also,  the  trend
toward managed health care in the united States, the organizations for which could control or significantly influence the purchase
of health care services and products, as well as legislative and regulatory proposals to reform health care or reduce government
insurance programs, may all result in lower prices for or rejection of our products. adoption of our

44

table of Contents

products by the medical community may be limited without adequate reimbursement for those products. Cost control initiatives
may decrease coverage and payment levels for our products and, in turn, the price that we will be able to charge for any product.
our products may not be considered cost-effective, and coverage and reimbursement may not be available or sufficient to allow
us to sell our products on a profitable basis. We are unable to predict all changes to the coverage or reimbursement methodologies
that will be applied by private or government payors to our current and any future approved products.

the  continuing  efforts  of  legislatures,  health  agencies  and  third-party  payors  to  contain  or  reduce  the  costs  of  health
care, any denial of private or government payor coverage or inadequate reimbursement for our drug candidates could materially
and adversely affect our business strategy, operations, future revenues and profitability, and the future revenues and profitability
of  our  potential  customers,  suppliers,  collaborators  and  licensees  and  the  availability  of  capital.    the  same  risks  apply  to  our
compounds  developed  and  marketed  by  our  collaborators,  and  our  future  potential  milestone  and  royalty  revenues  could  be
affected in a similar manner.

We  depend  on  our  collaborators  and  licensees  for  the  future  development  and  commercialization  of  some  of  our  drug
candidates. Conflicts may arise between our collaborators and licensees and us, or our collaborators and licensees may choose
to terminate their agreements with us, which may adversely affect our business.

We  have  licensed  to  novartis  rights  to  ruxolitinib  outside  of  the  united  States  and  worldwide  rights  to  our  mEt
inhibitor compounds, including taBrECta, and licensed to lilly worldwide rights to baricitinib. in addition, we have licensed
to innovent and to Zai lab certain asian rights to some of our clinical stage compounds.  under the terms of our agreements with
these collaborators, we have no or limited control over the further clinical development of these drug candidates in the relevant
territories and any revenues we may receive if these drug candidates receive regulatory approval and are commercialized in the
relevant territories will depend primarily on the development and commercialization efforts of others. While olumiant was
approved  by  the  European  Commission  in  February  2017  for  the  treatment  of  moderate-to-severe  rheumatoid  arthritis  in  adult
patients and by Japan’s ministry of health, labor and Welfare in July 2017 for the treatment of rheumatoid arthritis in patients
with  inadequate  response  to  standard-of-care  therapies,  the  nDa  for  olumiant  for  the  treatment  of  moderate-to-severe
rheumatoid  arthritis  was  approved  in  June  2018, and  only  in  the  lower  dosage  tablet  and  with  a  warning  label.    Delays  in  any
marketing approval by the FDa, European or other regulatory authorities, or any label modifications or restrictions in connection
with any such approval, or the existence of other risks relating to approved drug products, including those described under “risks
relating to Commercialization of our products,” could delay the receipt of and reduce resulting potential royalty and milestone
revenue from baricitinib or any of our other out-licensed drug candidates.  

Conflicts  may  arise  with  our  collaborators  and  licensees  if  they  pursue  alternative  technologies  or  develop  alternative
products either on their own or in collaboration with others as a means for developing treatments for the diseases that we have
targeted. Competing products and product opportunities may lead our collaborators and licensees to withdraw their support for
our drug candidates. any failure of our collaborators and licensees to perform their obligations under our agreements with them
or otherwise to support our drug candidates could negatively impact the development of our drug candidates, lead to our loss of
potential revenues from product sales and milestones and delay our achievement, if any, of profitability. additionally, conflicts
have from time to time occurred, and may in the future arise, relating to, among other things, disputes about the achievement and
payment  of  milestone  amounts,  the  ownership  of  intellectual  property  that  is  developed  during  the  course  of  a  collaborative
relationship or the operation or interpretation of other provisions in our collaboration agreements.  these disputes could lead to
litigation or arbitration, which could be costly and divert the efforts of our management and scientific staff, and could diminish
the expected effectiveness of the collaboration.  

our existing collaborative and license agreements can be terminated by our collaborators and licensees for convenience,
among other circumstances. if any of our collaborators or licensees terminates its agreement with us, or terminates its rights with
respect to certain indications or drug candidates, we may not be able to find a new collaborator for them, and our business could
be adversely affected. Should an agreement be terminated before we have realized the benefits of the collaboration or license, our
reputation  could  be  harmed,  we  may  not  obtain  revenues  that  we  anticipated  receiving,  and  our  business  could  be  adversely
affected.

The success of our drug discovery and development efforts may depend on our ability to find suitable collaborators to fully
exploit our capabilities. If we are unable to establish collaborations or if these future collaborations are unsuccessful in the
development and commercialization of our drug candidates, our research, development and commercialization efforts may be
unsuccessful, which could adversely affect our results of operations, financial condition and future revenue prospects.

an element of our business strategy is to enter into collaborative or license arrangements with other parties, under which
we  license  our  drug  candidates  to  those  parties  for  development  and  commercialization  or  under  which  we  study  our  drug
candidates in combination with other parties’ compounds or biologics. For example, in addition to our novartis, lilly, innovent
and Zai lab collaborations, we have entered into clinical study relationships with respect to several of our programs, including
epacadostat,  and  are  evaluating  strategic  relationships  with  respect  to  several  of  our  other  programs.  however,  because
collaboration  and  license  arrangements  are  complex  to  negotiate,  we  may  not  be  successful  in  our  attempts  to  establish  these
arrangements. also, we may not have drug candidates that are desirable to other parties, or we may be unwilling to license a drug
candidate  to  a  particular  party  because  such  party  interested  in  it  is  a  competitor  or  for  other  reasons.  the  terms  of  any  such
arrangements that we establish may not be favorable to us. alternatively, potential collaborators may decide against entering into
an agreement with us because of our financial, regulatory or intellectual property position or for scientific, commercial or other
reasons. if we are not able to establish collaboration or license arrangements, we may not be able to develop and commercialize a
drug product, which could adversely affect our business, our revenues and our future revenue prospects.

We will likely not be able to control the amount and timing of resources that our collaborators or licensees devote to our
programs  or  drug  candidates.  if  our  collaborators  or  licensees  prove  difficult  to  work  with,  are  less  skilled  than  we  originally
expected,  do  not  devote  adequate  resources  to  the  program,  are  unable  to  obtain  regulatory  approval  of  our  drug  candidates,
pursue  alternative  technologies  or  develop  alternative  products,  or  do  not  agree  with  our  approach  to  development  or
manufacturing  of  the  drug  candidate,  the  relationship  could  be  unsuccessful.  our  collaborations  with  respect  to  epacadostat
involved the study of our collaborators’ drugs used in combination with epacadostat on a number of indications or tumor types,
many of which were the same across multiple collaborations. We cannot assure you that potential conflicts will not arise or be
alleged among these collaborations. if a business combination involving a collaborator or licensee and a third-party were to occur,
the effect could be to terminate or cause delays in development of a drug candidate.

If we fail to enter into additional licensing agreements or if these arrangements are unsuccessful, our business and operations
might be adversely affected.

in addition to establishing collaborative or license arrangements under which other parties license our drug candidates
for  development  and  commercialization  or  under  which  we  study  our  drug  candidates  in  combination  with  such  parties’
compounds  or  biologics,  we  may  explore  opportunities  to  develop  our  clinical  pipeline  by  in-licensing  drug  candidates  or
therapeutics targets that fit within our focus on oncology, such as our collaborations with agenus inc., Calithera Biosciences, inc.,
macroGenics,  inc.,  merus  n.v.,  morphoSys,  and  Syros  pharmaceuticals,  inc.,  or  explore  additional  opportunities  to  further
develop  and  commercialize  existing  drug  candidates  in  specific  jurisdictions,  such  as  our  June  2016  acquisition  of  the
development and commercialization rights to iCluSiG in certain countries. We may be unable to enter into any additional in-
licensing agreements because suitable drug candidates that are within our expertise may not be available to us on terms that are
acceptable to us or because competitors with greater resources seek to in-license the same drug candidates. Drug candidates that
we  would  like  to  develop  or  commercialize  may  not  be  available  to  us  because  they  are  controlled  by  competitors  who  are
unwilling to license the rights to the drug candidate to us. in addition, we may enter into license agreements that are unsuccessful
and  our  business  and  operations  might  be  adversely  affected  if  we  are  unable  to  realize  the  expected  economic  benefits  of  a
collaboration  or other  licensing  arrangement,  by the termination  of a drug candidate  and termination  and winding down of the
related license agreement, or due to other business or regulatory issues, including financial difficulties, that may adversely affect a
licensor’s  ability  to  continue  to  perform  its  obligations  under  an  in-license  agreement.  For  example,  we  may  make  or  incur
contractual obligations to make significant upfront payments in connection with licenses for late-stage drug candidates, as we did
in  march  2020  in  connection  with  the  effectiveness  of  our  collaboration  agreement  with  morphoSys,  and  if  any  of  those  drug
candidates  do  not  receive  marketing  approval  or  commercial  sales  as  anticipated  or  we  have  to  fund  additional  clinical  trials
before marketing approval can be obtained, we will have expended significant funds that might otherwise be applied for other

46

table of Contents

uses  or  have  to  expend  funds  that  were  not  otherwise  budgeted  or  anticipated  in  connection  with  the  collaboration,  and  such
developments could have a material adverse effect on our stock price and our ability to pursue other transactions. as discussed
above under “We depend on our collaborators and licensees for the future development and commercialization of some of our
drug  candidates.  Conflicts  may  arise  between  our  collaborators  and  licensees  and  us,  or  our  collaborators  and  licensees  may
choose to terminate their agreements with us, which may adversely affect our business,” conflicts or other issues may arise with
our  licensors.  those  conflicts  could  result  in  delays  in  our  plans  to  develop  drug  candidates  or  result  in  the  expenditure  of
additional  funds to resolve those conflicts  that could have an adverse effect on our results of operations.  We may also need to
license  drug  delivery  or  other  technology  in  order  to  continue  to  develop  our  drug  candidates.  if  we  are  unable  to  enter  into
additional  agreements  to  license  drug  candidates,  drug  delivery  technology  or  other  technology  or  if  these  arrangements  are
unsuccessful, our research and development efforts could be adversely affected, and we may be unable to increase our number of
successfully marketed products and our revenues.

Even if a drug candidate that we develop receives regulatory approval, we may decide not to commercialize it if we determine
that commercialization of that product would require more money and time than we are willing to invest.

Even if any of our drug candidates receives regulatory approval, it could be subject to post-regulatory surveillance, and
may have to be withdrawn from the market or subject to restrictions if previously unknown problems occur. regulatory agencies
may  also require  additional  clinical  trials  or testing,  and the  drug  product  may  be recalled  or  may be  subject  to  reformulation,
additional  studies,  changes  in  labeling,  warnings  to  the  public  and  negative  publicity.  as  a  result,  we  may  not  continue  to
commercialize  a  product  even  though  it  has  obtained  regulatory  approval.  Further,  we  may  decide  not  to  continue  to
commercialize  a product  if  the market  does not accept  the product  because  it is too expensive  or because  third  parties  such as
insurance companies or medicare, have not approved it for substantial reimbursement. in addition, we may decide not to continue
to commercialize a product if competitors develop and commercialize similar or superior products or have proprietary rights that
preclude us from ultimately marketing our products.

Any approved drug product that we bring to the market may not gain market acceptance by physicians, patients, healthcare
payors and others in the medical community.

Even if we or our collaborators are successful in gaining regulatory approval of any of our or our collaborators’  drug
candidates  in  addition  to  JaKaFi,  olumiant,  pEmaZYrE  and  monJuvi  or  acquire  rights  to  approved  drug  products  in
addition to iCluSiG, we may not generate significant product revenues if these drug products do not achieve an adequate level of
acceptance. physicians may not recommend our or our collaborators’ drug products until longer-term clinical data or other factors
demonstrate the safety and efficacy of our or our collaborators’ drug products as compared to other alternative treatments. Even if
the  clinical  safety  and  efficacy  of  our  or  our  collaborators’  drug  products  is  established,  physicians  may  elect  not  to  prescribe
these drug products for a variety of reasons, including the reimbursement policies of government and other third-party payors and
the effectiveness of our or our collaborators’ competitors in marketing their products.

market acceptance of our drug products, if approved for commercial sale, will depend on a number of factors, including

the following, and market acceptance of our collaborators’ drug products will depend on similar factors:

●

●

●

●

●

the willingness and ability of patients and the healthcare community to use our drug products;

the ability to manufacture our drug products in sufficient quantities that meet all applicable quality standards and to
offer our drug products for sale at competitive prices;

the perception of patients and the healthcare community, including third-party payors, regarding the safety, efficacy
and benefits of our drug products compared to those of competing products or therapies;

the label and promotional claims allowed by the FDa;

the pricing and reimbursement of our drug products relative to existing treatments; and

47

table of Contents

● marketing and distribution support for our drug products.

We have limited capacity to conduct preclinical testing and clinical trials, and our resulting dependence on other parties could
result in delays in and additional costs for our drug development efforts.

We  have  limited  internal  resources  and  capacity  to  perform  preclinical  testing  and  clinical  trials.  as  part  of  our
development strategy, we often hire clinical research organizations, or Cros, to perform preclinical testing and clinical trials for
drug candidates. if the Cros that we hire to perform our preclinical testing and clinical trials do not meet deadlines, do not follow
proper procedures, or a conflict arises between us and our Cros, our preclinical testing and clinical trials may take longer than
expected, may cost more, may be delayed or may be terminated. if we were forced to find a replacement entity to perform any of
our preclinical testing or clinical trials, we may not be able to find a suitable entity on favorable terms, or at all. Even if we were
able to find another company to perform a preclinical test or clinical trial, the delay in the test or trial may result in significant
additional expenditures. Events such as these may result in delays in our obtaining regulatory approval for our drug candidates or
our  ability  to  commercialize  our  products  and  could  result  in  increased  expenditures  that  would  adversely  affect  our  operating
results.

We  face  significant  competition  for  our  drug  discovery  and  development  efforts,  and  if  we  do  not  compete  effectively,  our
commercial opportunities will be reduced or eliminated.

the  biotechnology  and  pharmaceutical  industries  are  intensely  competitive  and  subject  to  rapid  and  significant
technological change. our drug discovery and development efforts may target diseases and conditions that are already subject to
existing  therapies  or  that  are  being  developed  by  our  competitors,  many  of  which  have  substantially  greater  resources,  larger
research  and  development  staffs  and  facilities,  more  experience  in  completing  preclinical  testing  and  clinical  trials,  and
formulation, marketing and manufacturing capabilities. as a result of these resources, our competitors may develop drug products
that  render  our  products  obsolete  or  noncompetitive  by  developing  more  effective  drugs,  developing  their  products  more
efficiently  or  pricing  their  products  more  competitively.  our  ability  to  develop  competitive  products  would  be  limited  if  our
competitors succeeded in obtaining regulatory approvals for drug candidates more rapidly than we were able to or in obtaining
patent protection or other intellectual property rights that limited our drug development efforts. any drug products resulting from
our  research  and  development  efforts,  or  from  our  joint  efforts  with  collaborators  or  licensees,  might  not  be  able  to  compete
successfully with our competitors’ existing and future products, or obtain regulatory approval in the united States or elsewhere.
the development of products or processes by our competitors with significant advantages over those that we are developing could
harm our future revenues and profitability.

Our  reliance  on  other  parties  to  manufacture  our  drug  products  and  drug  candidates  could  result  in  a  short  supply  of  the
drugs,  delays  in  clinical  trials  or  drug  development,  increased  costs,  and  withdrawal  or  denial  of  a  regulatory  authority’s
approval.

We  do  not  currently  operate  manufacturing  facilities  for  clinical  or  commercial  production  of  JaKaFi,  pEmaZYrE
and our other drug candidates or for iCluSiG or monJuvi. We currently hire third parties to manufacture the raw materials,
api  and  finished  drug  product  of  JaKaFi,  iCluSiG,  pEmaZYrE  and  our  other  drug  candidates  for  clinical  trials  and  our
collaborator morphoSys is currently responsible for sourcing manufacturing of monJuvi.  in addition, we expect to continue to
rely on third parties for the manufacture of commercial supplies of raw materials, api and finished drug product for any drugs
that we successfully develop. We also hire third parties to package and label the finished product. the FDa requires that the raw
materials,  api  and  finished  product  for  drug  products  such  as  JaKaFi  and  pEmaZYrE  and  our  other  drug  candidates  be
manufactured according to its current Good manufacturing practices regulations and regulatory authorities in other countries have
similar requirements. there are only a limited number of manufacturers that comply with these requirements. Failure to comply
with current Good manufacturing practices and the applicable regulatory requirements of other countries in the manufacture of
our drug candidates and products could result in the FDa or a foreign regulatory authority halting our clinical trials, withdrawing
or denying regulatory approval of our drug product, enforcing product recalls or other enforcement actions, which could have a
material adverse effect on our business.

We may not be able to obtain sufficient quantities of our drug candidates or any drug products we may develop if our

designated manufacturers do not have the capacity or capability to manufacture them according to our schedule and

48

table of Contents

specifications. manufacturers of pharmaceutical products often encounter difficulties in production, especially in scaling up initial
production. these problems include difficulties with production costs and yields, quality control and assurance and shortages of
qualified personnel.  to the extent our supply chain involves parties in China or materials originating in areas of China that are or
could be affected by disease outbreaks such as the CoviD-19 pandemic in 2020, we could see disruptions to our supply chain.
Currently, our supply chain for our drug products and product candidates depends on operations by us and by other companies in
multiple  countries  around  the  world,  and  the  effects  of  the  CoviD-19  pandemic  and  measures  to  address  the  CoviD-19
pandemic on any or all of these countries is uncertain and unpredictable and potential disruption is possible. and, for JaKaFi,
while our strategy is to maintain a 24 months stock of api, inclusive of finished product, ruxolitinib phosphate might be used by
us either to make JaKaFi or for ruxolitinib drug candidates in clinical trials. in addition, we may not be able to arrange for our
drug candidates or any drug products that we may develop to be manufactured by one of these parties on reasonable terms, if at
all.  We generally have a single source or a limited number of suppliers that are qualified to supply each of the api and finished
product of our drug products and our other drug candidates and, in the case of JaKaFi, we only have a single source for its raw
materials. if any of these suppliers were to become unable or unwilling to supply us with raw materials, api or finished product
that complies with applicable  regulatory  requirements,  we could incur significant delays in our clinical trials  or interruption  of
commercial supply that could have a material adverse effect on our business. if we have promised delivery of a drug candidate or
drug product and are unable to meet the delivery requirement due to manufacturing difficulties, our development programs could
be delayed, we may have to expend additional sums in order to ensure that manufacturing capacity is available when we need it
even if we do not use all of the manufacturing capacity, and our business and operating results could be harmed.

We may not be able to adequately manage and oversee the manufacturers we choose, they may not perform as agreed or
they  may  terminate  their  agreements  with  us.  Foreign  manufacturing  approval  processes  typically  include  all  of  the  risks
associated with the FDa approval process for manufacturing and may also include additional risks.

a  number  of  our  collaborations  involve  the  manufacture  of  antibodies.  Either  we  or  our  collaborators  have  primary
responsibility  for  manufacturing  activities,  and  we  are  currently  using  third-party  contract  manufacturing  organizations.
manufacturing  antibodies  and  products  containing  antibodies  is  a  more  complex  process  than  manufacturing  small  molecule
drugs  and  subject  to  additional  risks.  the  process  of  manufacturing  antibodies  and  products  containing  antibodies  is  highly
susceptible to product loss due to contamination, equipment failure or improper installation or operation of equipment, vendor or
operator error, inconsistency in yields, variability in product characteristics, and difficulties in scaling up the production process.
Even minor deviations from normal manufacturing processes could result in reduced production yields, product defects and other
supply disruptions. if microbial, viral or other contaminations are discovered in our product candidates or in the manufacturing
facilities in which our product candidates are made, such manufacturing facilities may need to be closed for an extended period of
time to investigate and remedy the contamination.

If  we  fail  to  comply  with  the  extensive  legal  and  regulatory  requirements  affecting  the  health  care  industry,  we  could  face
increased costs, penalties and a loss of business.

our  activities,  and  the  activities  of  our  collaborators,  partners  and  third-party  providers,  are  subject  to  extensive
government regulation and oversight both in the united States and in foreign jurisdictions. the FDa and comparable agencies in
other jurisdictions directly regulate many of our most critical business activities, including the conduct of preclinical and clinical
studies,  product  manufacturing,  advertising  and  promotion,  product  distribution,  adverse  event  reporting  and  product  risk
management. States increasingly have been placing greater restrictions on the marketing practices of healthcare companies and
have instituted pricing disclosure and other requirements for companies selling pharmaceuticals. in addition, pharmaceutical and
biotechnology  companies  have  been  the  target  of  lawsuits  and  investigations  alleging  violations  of  government  regulations,
including  claims  asserting  submission  of  incorrect  pricing  information,  improper  promotion  of  pharmaceutical  products,
payments  intended  to  influence  the  referral  of  federal  or  state  healthcare  business,  submission  of  false  claims  for  government
reimbursement, antitrust violations, violations of the u.S. Foreign Corrupt practices act, the u.K. Bribery act and similar anti-
bribery  or  anti-corruption  laws,  or  violations  related  to  environmental  matters.  there  is  also  enhanced  scrutiny  of  company-
sponsored patient assistance programs, including insurance premium and co-pay assistance programs and donations to third-party
charities that provide such assistance. in December 2018, we received a civil investigative demand from the u.S. Department of
Justice for documents and information relating to our speaker programs and patient assistance programs, including our support of
non-profit  organizations  that  provide  financial  assistance  to  eligible  patients.  violations  of  governmental  regulation  by  us,  our
vendors

49

table of Contents

or donation recipients may be punishable by criminal and civil sanctions, including damages, fines and penalties and exclusion
from  participation  in  government  programs,  including  medicare  and  medicaid.  in  addition  to  damages,  fines  and  penalties  for
violation of laws and regulations, we could be required to repay amounts we received from government payors, or pay additional
rebates and interest if we are found to have miscalculated the pricing information we have submitted to the government. actions
taken  by  federal  or  local  governments,  legislative  bodies  and  enforcement  agencies  with  respect  to  these  legal  and  regulatory
compliance matters could also result in reduced demand for our products, reduced coverage of our products by health care payors,
or  both.  We  cannot  ensure  that  our  compliance  controls,  policies,  and  procedures  will  in  every  instance  protect  us  from  acts
committed  by  our  employees,  collaborators,  partners  or  third-party  providers  that  would  violate  the  laws  or  regulations  of  the
jurisdictions in which we operate. Whether or not we have complied with the law, an investigation into alleged unlawful conduct
could  increase  our  expenses,  damage  our  reputation,  divert  management  time  and  attention  and  adversely  affect  our  business.
risks relating to compliance with laws and regulations may be heightened as we continue to expand our global operations and
enter  new  therapeutic  areas  with  different  patient  populations,  which  due  to  different  product  distribution  methods,  marketing
programs or patient assistance programs may result in additional regulatory burdens and obligations.

The illegal distribution and sale by third parties of counterfeit or unfit versions of our or our collaborators’ products or stolen
products could harm our business and reputation.

We  are  aware  that  counterfeit  versions  of  our  products  have  been  distributed  or  sold  by  entities  not  authorized  by  us
using product packaging suggesting that the product was provided by us. if unauthorized third parties illegally distribute and sell
counterfeit  versions  of  our  or  our  collaborators’  products,  those  products  may  not  meet  our  or  our  collaborators’  rigorous
manufacturing,  distribution  and  handling  standards.  in  addition,  inventory  that  is  stolen  from  warehouses,  plants  or  while  in-
transit, and that is subsequently improperly stored and sold through unauthorized channels, may not meet our or our collaborators’
distribution and handling standards. a patient who receives a counterfeit or unfit drug may suffer dangerous health consequences.
 our reputation and business could suffer harm as a result of counterfeit or unfit drugs sold under our brand name and could result
in lost sales for us and decreased revenues. if counterfeit or unfit drugs are sold under our or our collaborators’ brand names, our
reputation and business could suffer harm and we could experience decreased royalty revenues.

As most of our drug discovery and development operations are conducted at our headquarters in Wilmington, Delaware, the
loss of access to this facility would negatively impact our business.

our  facility  in  Wilmington,  Delaware  is  our  headquarters  and  is  also  where  we  conduct  most  of  our  drug  discovery,
research, development and marketing activities. in addition, natural disasters, the effects of or measures taken to limit the effects
of health epidemics such as the CoviD-19 pandemic, or actions of activists opposed to aspects of pharmaceutical research may
disrupt  our  experiments  or  our  ability  to  access  or  use  our  facility.  the  loss  of  access  to  or  use  of  our  Wilmington,  Delaware
facility,  either  on  a  temporary  or  permanent  basis,  would  result  in  an  interruption  of  our  business  and,  consequently,  would
adversely affect our overall business.

We  depend  on  key  employees  in  a  competitive  market  for  skilled  personnel,  and  the  loss  of  the  services  of  any  of  our  key
employees or our inability to attract and retain additional personnel would affect our ability to expand our drug discovery and
development programs and achieve our objectives.

We are highly dependent on the members of our executive management team and principal members of our commercial,
development,  medical,  operations  and  scientific  staff.  We  experience  intense  competition  for  qualified  personnel.  our  future
success  also  depends  in part  on the continued  service  of  our  executive  management  team  and  key  personnel  and  our ability  to
recruit,  train  and  retain  essential  personnel  for  our  drug  discovery  and  development  programs,  and  for  our  medical  affairs  and
commercialization  activities.  if  we  lose  the  services  of  any  of  these  people  or  if  we  are  unable  to  recruit  sufficient  qualified
personnel, our research and product development goals, and our commercialization efforts could be delayed or curtailed. We do
not maintain “key person” insurance on any of our employees.

If we fail to manage our growth effectively, our ability to develop and commercialize products could suffer.

We expect that if our drug discovery efforts continue to generate drug candidates, our clinical drug candidates continue
to progress in development, and we continue to build our development, medical and commercial organizations, we will require
significant additional investment in personnel, management and resources. our ability to achieve our research, development and
commercialization  objectives  depends  on  our  ability  to  respond  effectively  to  these  demands  and  expand  our  internal
organization,  systems,  controls  and  facilities  to  accommodate  additional  anticipated  growth.  if  we  are  unable  to  manage  our
growth effectively, our business could be harmed and our ability to execute our business strategy could suffer.

We may acquire businesses or assets, form joint ventures or make investments in other companies that may be unsuccessful,
divert our management’s attention and harm our operating results and prospects.

as  part  of  our  business  strategy,  we  may  pursue  additional  acquisitions  of  what  we  believe  to  be  complementary
businesses  or  assets  or  seek  to  enter  into  joint  ventures.  We  also  may  pursue  strategic  alliances  in  an  effort  to  leverage  our
existing  infrastructure  and  industry  experience  to  expand  our  product  offerings  or  distribution,  or  make  investments  in  other
companies. For example, in June 2016, we completed the acquisition of the European operations of ariaD. the success of our
acquisitions, joint ventures, strategic alliances and investments will depend on our ability to identify, negotiate, complete and, in
the case of acquisitions, integrate those transactions and, if necessary, obtain satisfactory debt or equity financing to fund those
transactions.  We may not realize the anticipated benefits of any acquisition, joint venture, strategic alliance or investment. We
may  not  be  able  to  integrate  acquisitions  successfully  into  our  existing  business,  achieve  planned  synergies  or  cost  savings,
maintain the key business relationships of businesses we acquire, or retain key personnel of an acquired business, and we could
assume unknown or contingent liabilities or incur unanticipated expenses. integration of acquired companies or businesses also
may  require  management  resources  that  otherwise  would  be  available  for  ongoing  development  of  our  existing  business.  any
acquisitions  or  investments  made  by  us  also  could  result  in  significant  write-offs  or  the  incurrence  of  debt  and  contingent
liabilities,  any of  which could  harm  our operating  results.  For example,  in the  three  month  periods  ended march  31, 2020 and
September 30, 2020, we recorded unrealized losses related to all of our investments in our collaboration partners, and we may in
experience additional losses related to our investments in future period.  in addition, if we choose to issue shares of our stock as
consideration for any acquisition, dilution to our stockholders could result.

Risks associated with our operations outside of the United States could adversely affect our business.

our  acquisition  of  ariaD’s  European  operations  significantly  expanded  our  operations  in  Europe,  and  we  plan  to
continue to expand our operations and conduct certain development activities outside of the united States.  For example, as part
of  our  plans  to  expand  our  activities  outside  of  the  united  States,  we  now  conduct  some  of  our  operations  in  Canada,  drug
development  activities  in  Japan  and  are  in  the  process  of  opening  an  office  in  China.  international  operations  and  business
expansion plans are subject to numerous additional risks, including:

● multiple,  conflicting  and  changing  laws  and  regulations  such  as  tax  laws,  privacy  regulations,  tariffs,  export  and
import  restrictions,  employment,  immigration  and  labor  laws,  regulatory  requirements,  and  other  governmental
approvals,  permits  and  licenses,  compliance  with  which  can  increase  in  complexity  as  we  enter  into  additional
jurisdictions;

●

●

●

difficulties in staffing and managing operations in diverse countries and difficulties in connection with assimilating
and integrating any operations and personnel we might acquire  into our company;

risks  associated  with  obtaining  and  maintaining,  or  the  failure  to  obtain  or  maintain,  regulatory  approvals  for  the
sale or use of our products in various countries;

complexities  associated  with  managing  government  payor  systems,  multiple  payor-reimbursement  regimes  or
patient self-pay systems;

51

table of Contents

●

●

●

●

financial risks, such as longer payment cycles, difficulty obtaining financing in foreign markets, difficulty enforcing
contracts and intellectual property rights, difficulty collecting accounts receivable and exposure to foreign currency
exchange rate fluctuations;

general  political  and  economic  conditions  in  the  countries  in  which  we  operate,  including  terrorism  and  political
unrest, curtailment of trade and other business restrictions, and uncertainties associated with the implementation of
the relationship between the united Kingdom and the European union;

public health risks, such as the spread globally of CoviD-19 in 2020, and related effects on supply chain, travel and
employee health and availability; and

regulatory and compliance risks that relate to maintaining accurate information and control over activities that may
fall within the purview of the u.S. Foreign Corrupt practices act, its books and records provisions or its anti-bribery
provisions, or similar anti-bribery or anti-corruption laws and regulations in other countries, such as the u.K. anti-
Bribery act and the u.K. Criminal Finances act, which may have similarly broad extraterritorial reach.

in  addition,  our  revenues  are  subject  to  foreign  currency  exchange  rate  fluctuations  due  to  the  global  nature  of  our
operations.  to  the  extent  that  our  non-u.S.  source  revenues  represent  a  more  significant  portion  of  our  total  revenues,  these
fluctuations  could  materially  affect  our  operating  results.  any  of  the  risks  described  above,  if  encountered,  could  significantly
increase our costs of operating internationally, prevent us from operating in certain jurisdictions, or otherwise significantly harm
our future international expansion and operations, which could have a material adverse effect on our business, financial condition
and results of operations.

If  product  liability  lawsuits  are  brought  against  us,  we  could  face  substantial  liabilities  and  may  be  required  to  limit
commercialization of our products and our results of operations could be harmed.

in addition to the risks described above under “—risks relating to Commercialization of our products—if the use of
our products harms patients, or is perceived to harm patients even when such harm is unrelated to our products, our regulatory
approvals  could  be  revoked  or  otherwise  negatively  impacted  or  we  could  be  subject  to  costly  and  damaging  product  liability
claims,”  the  conduct  of  clinical  trials  of  medical  products  that  are  intended  for  human  use  entails  an  inherent  risk  of  product
liability.  if  any  product  that  we  or  any  of  our  collaborators  or  licensees  develops  causes  or  is  alleged  to  cause  injury  during
clinical trials or commercialization, we may be held liable. if we cannot successfully defend ourselves against product liability
claims, we may incur substantial liabilities, including substantial damages to be paid to the plaintiffs and legal costs, or we may
be required to limit further development and commercialization of our products. additionally, any product liability lawsuit could
cause  injury  to  our  reputation,  participants  and  investigators  to  withdraw  from  clinical  trials,  and  potential  collaborators  or
licensees to seek other partners, any of which could impact our results of operations.

our product liability insurance policy may not fully cover our potential liabilities. in addition, we may determine that we
should increase our coverage, and this insurance may be prohibitively expensive to us or our collaborators or licensees and may
not fully cover our potential liabilities. Since December 30, 2017, we elected to self-insure a portion of our exposure to product
liability risks through our wholly-owned captive insurance subsidiary, in tandem with third-party insurance policies. our inability
to  obtain  sufficient  product  liability  insurance  at  an  acceptable  cost  to  protect  against  potential  product  liability  claims  could
prevent or inhibit the development or commercialization of our drug candidates and products, and if our liabilities from any such
claims  exceed  our  third-party  insurance  limits  and  self-insurance  reserves,  our  results  of  operations,  cash  flows  and  financial
condition could be adversely impacted.

Because  our  activities  involve  the  use  of  hazardous  materials,  we  may  be  subject  to  claims  relating  to  improper  handling,
storage or disposal of these materials that could be time consuming and costly.

We are subject to various environmental, health and safety laws and regulations governing, among other things, the use,
handling, storage and disposal of regulated substances and the health and safety of our employees. our research and development
processes involve the controlled use of hazardous and radioactive materials and biological waste resulting

52

table of Contents

in the production of hazardous waste products. We cannot completely eliminate the risk of accidental contamination or discharge
and any resultant injury from these materials. if any injury or contamination results from our use or the use by our collaborators
or licensees of these materials, we may be sued and our liability may exceed our insurance coverage and our total assets. Further,
we  may  be  required  to  indemnify  our  collaborators  or  licensees  against  all  damages  and  other  liabilities  arising  out  of  our
development activities or products produced in connection with these collaborations or licenses. Compliance with the applicable
environmental and workplace laws and regulations is expensive. Future changes to environmental, health, workplace and safety
laws could cause us to incur additional expense or may restrict our operations or impair our research, development and production
efforts.

 RISKS RELATING TO OUR FINANCIAL RESULTS

We  may  incur  losses  in  the  future,  and  we  expect  to  continue  to  incur  significant  expenses  to  discover  and  develop  drugs,
which may make it difficult for us to achieve sustained profitability on a quarterly or annual basis in the future.

Due  to  historical  net  losses,  we  had  an  accumulated  deficit  of  $1.7  billion  as  of  December  31,  2020.  We  intend  to
continue to spend significant  amounts on our efforts  to discover and develop drugs. as a result, we may incur losses in future
periods as well. our revenues, expenses and net income (loss) may fluctuate, even significantly, due to the risks described in these
“risk  Factors”  and  factors  discussed  in  “management’s  Discussion  and  analysis  of  Financial  Condition  and  results  of
operations”  as  well  as  the  timing  of  charges  and  expenses  that  we  may  take,  including  those  relating  to  transactions  such  as
acquisitions and the entry into collaborative agreements.

We anticipate that our drug discovery and development efforts and related expenditures will increase as we focus on the
studies, including preclinical tests and clinical trials prior to seeking regulatory approval, that are required before we can sell a
drug product.

the development of drug products will require us to spend significant funds on research, development, testing, obtaining
regulatory approvals, manufacturing and marketing. to date, we do not have any drug products that have generated significant
revenues other than from sales of JaKaFi and we cannot assure you that we will generate  substantial  revenues from the drug
candidates that we license or develop, including iCluSiG, pEmaZYrE and monJuvi, for several years, if ever.

We cannot be certain whether or when we will achieve sustained or increased profitability on a quarterly or annual basis
because of the factors discussed above and the significant uncertainties relating to our ability to generate commercially successful
drug products. Even if we are successful in obtaining regulatory approvals for manufacturing and commercializing drug products
in  addition  to  JaKaFi,  iCluSiG,  pEmaZYrE  and  monJuvi,  we  may  incur  losses  if  our  drug  products  do  not  generate
significant revenues.

We  may  need  additional  capital  in  the  future.  If  we  are  unable  to  generate  sufficient  funds  from  operations,  the  capital
markets may not permit us to raise additional capital at the time that we require it, which could result in limitations on our
research  and  development  or  commercialization  efforts  or  the  loss  of  certain  of  our  rights  in  our  technologies  or  drug
candidates.

our  future  funding  requirements  will  depend  on  many  factors  and  we anticipate  that  we may  need  to  raise  additional

capital to fund our business plan and research and development efforts going-forward.

additional factors that may affect our future funding requirements include:

●

●

●

the acquisition of businesses, technologies, or drug candidates, or the licensing of technologies or drug candidates,
if any;

the amount of revenues generated from our business activities;

any changes in the breadth of our research and development programs;

53

table of Contents

●

●

●

●

●

●

●

the  results  of  research  and  development,  preclinical  testing  and  clinical  trials  conducted  by  us  or  our  current  or
future collaborators or licensees, if any;

our exercise of any co-development options with collaborators that may require us to fund future development;

costs for future facility requirements;

our ability to maintain and establish new corporate relationships and research collaborations;

competing technological and market developments;

the time and costs involved in filing, prosecuting, defending and enforcing patent and intellectual property claims;

the receipt or payment of contingent licensing or milestone fees or royalties on product sales from our current or
future collaborative and license arrangements, if established; and

●

the timing of regulatory approvals, if any.

if we require additional capital at a time when investment in companies such as ours, or in the marketplace generally, is
limited due to the then prevailing market or other conditions, we may have to scale back our operations, eliminate one or more of
our research or development programs, or attempt to obtain funds by entering into an agreement with a collaborator or licensee
that would result in terms that are not favorable to us or relinquishing our rights in certain of our proprietary technologies or drug
candidates. if we are unable to raise funds at the time that we desire or at any time thereafter on acceptable terms, we may not be
able to continue to develop our drug candidates. the sale of equity or equity-linked securities in the future may be dilutive to our
stockholders  and  may  provide  for  rights,  preferences  or  privileges  senior  to  those  of  our  holders  of  common  stock,  and  debt
financing arrangements may require us to pledge certain assets or enter into covenants that could restrict our operations or our
ability to pay dividends or other distributions on our common stock or incur further indebtedness.

Our  marketable  securities  and  long  term  investments  are  subject  to  risks  that  could  adversely  affect  our  overall  financial
position.

We  invest  our  cash  in  accordance  with  an  established  internal  policy  and  customarily  in  instruments,  money  market
funds, u.S. government backed-funds and treasury assets, which historically have been highly liquid and carried relatively low
risk. in recent periods, similar types of investments and money market funds have experienced losses in value or liquidity issues
that differ from their historical pattern.

Should a portion of our cash or marketable securities lose value or have their liquidity impaired, it could adversely affect
our overall financial position by imperiling our ability to fund our operations and forcing us to seek additional financing sooner
than we would otherwise. Such financing, if available, may not be available on commercially attractive terms.

as discussed under “other risks relating to our Business— We may acquire businesses or assets, form joint ventures
or  make  investments  in  other  companies  that  may  be  unsuccessful,  divert  our  management’s  attention  and  harm  our  operating
results and prospects,” any investments that we may make in companies with which we have strategic alliances, such as agenus
and  merus,  could  result  in  our  recognition  of  losses  on  those  investments.  in  addition,  to  the  extent  we  may  seek  to  sell  or
otherwise monetize those investments, we may not be able to do so at our desired price or valuation levels, or at all, due to the
limited liquidity of some or all of those investments.

any loss in value of our long term investments could adversely affect our financial position on the consolidated balance

sheets and consolidated statements of operations.

54

table of Contents

We  derive  a  substantial  portion  of  our  revenues  from  royalties,  milestone  payments  and  other  payments  under  our
collaboration agreements. If we are unable to achieve milestones, develop product candidates to license or renew or enter into
new collaborations, our revenues may decrease, and future milestone and royalty payments may not contribute significantly to
revenues for several years, and may never result in revenues.

We derived a substantial portion of our revenues for the year ended December 31, 2020 from JaKavi and olumiant
product  royalties  and  from  milestone  payments  under  our  collaboration  agreements.  Future  revenues  from  research  and
development collaborations depend upon continuation of the collaborations, the achievement of milestones and royalties we earn
from any future products developed from our research. if we are unable to successfully achieve milestones or our collaborators
fail to develop successful products, we will not earn the future revenues contemplated under our collaborative agreements.  For
example,  delays  in  or  other  limitations  with  respect  to  the  approval  of  baricitinib  in  the  united  States  for  the  treatment  of
moderate-to-severe  rheumatoid  arthritis,  or  the  failure  to  obtain  such  approval,  as  discussed  under  “—We  depend  on  our
collaborators and licensees for the future development and commercialization of some of our drug candidates. Conflicts may arise
between our collaborators and licensees and us, or our collaborators and licensees may choose to terminate their agreements with
us, which may adversely affect our business.” would affect potential future royalty and milestone and contract revenue.

RISKS RELATING TO INTELLECTUAL PROPERTY AND LEGAL MATTERS

If we are subject to arbitration, litigation and infringement claims, they could be costly and disrupt our drug discovery and
development efforts.

the technology that we use to make and develop our drug products, the technology that we incorporate in our products,
and the products we are developing  may be subject to claims  that they infringe  the patents or proprietary rights of others. the
success  of  our  drug  discovery  and  development  efforts  will  also  depend  on  our  ability  to  develop  new  compounds,  drugs  and
technologies  without  infringing  or  misappropriating  the  proprietary  rights  of  others.  We  are  aware  of  patents  and  patent
applications  filed  in  certain  countries  claiming  intellectual  property  relating  to  some  of  our  drug  discovery  targets  and  drug
candidates. While the validity of issued patents, patentability of pending patent applications and applicability of any of them to
our  programs  are  uncertain,  if  any  of  these  patents  are  asserted  against  us  or  if  we  choose  to  license  any  of  these  patents,  our
ability to commercialize  our products could be harmed or the potential return to us from any product that may be successfully
commercialized could be diminished.

From time to time  we have received,  and we may in the future  receive,  notices from third parties  offering  licenses  to
technology  or  alleging  patent,  trademark,  or  copyright  infringement,  claims  regarding  trade  secrets  or  other  contract  claims.
receipt of these notices could result in significant costs as a result of the diversion of the attention of management from our drug
discovery and development efforts. parties sending these notices may have brought and in the future may bring litigation against
us or seek arbitration relating to contract claims.

We  may  be  involved  in  future  lawsuits  or  other  legal  proceedings  alleging  patent  infringement  or  other  intellectual

property rights or contract violations. in addition, litigation or other legal proceedings may be necessary to:

●

●

●

●

assert claims of infringement;

enforce our patents or trademarks;

protect our trade secrets or know-how; or

determine the enforceability, scope and validity of the proprietary rights of others.

We may be unsuccessful in defending or pursuing these lawsuits, claims or other legal proceedings. regardless of the
outcome, litigation or other legal proceedings can be very costly and can divert management’s efforts. an adverse determination
may subject us to significant liabilities or require us or our collaborators or licensees to seek licenses to other parties’ patents or
proprietary rights. We or our collaborators or licensees may also be restricted or prevented from manufacturing or selling a drug
or other product that we or they develop. Further, we or our future collaborators or licensees

55

table of Contents

may  not  be  able  to  obtain  any  necessary  licenses  on  acceptable  terms,  if  at  all.  if  we  are  unable  to  develop  non-infringing
technology or license technology on a timely basis or on reasonable terms, our business could be harmed.

We may be unable to adequately protect or enforce our proprietary information, which may result in its unauthorized use, a
loss of revenue under a collaboration agreement or loss of sales to generic versions of our products or otherwise reduce our
ability to compete in developing and commercializing products.

our business and competitive position depends in significant part upon our ability to protect our proprietary technology,
including any drug products that we create. Despite our efforts to protect this information, unauthorized parties may attempt to
obtain  and  use  information  that  we  regard  as  proprietary.  For  example,  one  of  our  collaborators  may  disclose  proprietary
information pertaining to our drug discovery efforts. in addition, while we have filed numerous patent applications with respect to
ruxolitinib  and  our  drug  candidates  in  the  united  States  and  in  foreign  countries,  our  patent  applications  may  fail  to  result  in
issued  patents.  in  addition,  because  patent  applications  can  take  several  years  to  issue  as  patents,  there  may  be  pending  patent
applications of others that may later issue as patents that cover some aspect of ruxolitinib and our drug candidates. our existing
patents and any future patents we may obtain may not be broad enough to protect our products or all of the potential uses of our
products,  or  otherwise  prevent  others  from  developing  competing  products  or  technologies.  in  addition,  our  patents  may  be
challenged and invalidated or may fail to provide us with any competitive advantages if, for example, others were first to invent
or  first  to  file  a  patent  application  for  the  technologies  and  products  covered  by  our  patents.    as  noted  above  under  “—risks
relating to Commercialization of our products—Competition for our products could potentially harm our business and result in a
decrease in our revenue,” a potential generic drug company competitor has challenged certain patents relating to JaKaFi.

additionally,  when  we  do  not  control  the  prosecution,  maintenance  and  enforcement  of  certain  important  intellectual
property,  such  as  a  drug  candidate  in-licensed  to  us  or  subject  to  a  collaboration  with  a  third-party,  the  protection  of  the
intellectual  property rights may not be in our hands. if we do not control the intellectual  property rights in-licensed  to us with
respect to a drug candidate and the entity that controls the intellectual property rights does not adequately protect those rights, our
rights may be impaired, which may impact our ability to develop, market and commercialize the in-licensed drug candidate.

our means of protecting our proprietary rights may not be adequate, and our competitors may:

●

●

●

independently develop substantially equivalent proprietary information, products and techniques;

otherwise gain access to our proprietary information; or

design around patents issued to us or our other intellectual property.

We  pursue  a  policy  of  having  our  employees,  consultants  and  advisors  execute  proprietary  information  and  invention
agreements  when  they  begin  working  for  us.  however,  these  agreements  may  not  provide  meaningful  protection  for  our  trade
secrets  or  other  proprietary  information  in  the  event  of  unauthorized  use  or  disclosure.  if  we  fail  to  maintain  trade  secret  and
patent protection, our potential future revenues may be decreased.

If the effective term of our patents is decreased due to changes in the United States patent laws or if we need to refile some of
our patent applications, the value of our patent portfolio and the revenues we derive from it may be decreased.

the value of our patents depends, in part, on their duration. a shorter period of patent protection could lessen the value
of our rights under any patents that we obtain and may decrease the revenues we derive from our patents. the united States patent
laws provide a term of patent protection of 20 years from the earliest effective filing date of the patent application. Because the
time from filing to issuance of biotechnology applications may be more than three years depending on the subject matter, a 20-
year patent term from the filing date may result in substantially shorter patent protection.

additionally, united States patent laws were amended in 2011 with the enactment of the america invents act and third
parties  are  now  able  to  challenge  the  validity  of  issued  u.S.  patents  through  various  review  proceedings;  thus  rendering  the
validity of u.S. patents more uncertain. We may be obligated to participate in review proceedings to

56

table of Contents

determine the validity of our u.S. patents. We cannot predict the ultimate outcome of these proceedings, the conduct of which
could result in substantial costs and diversion of our efforts and resources. if we are unsuccessful in these proceedings some or all
of our claims in the patents may be narrowed or invalidated and the patent protection for our products and drug candidates in the
united States could be substantially shortened. Further, if all of the patents covering one of our products are invalidated, the FDa
could approve requests to manufacture a generic version of that product prior to the expiration date of those patents.

other changes in the united States patent laws or changes in the interpretation of patent laws could diminish the value of
our patents or narrow the scope of our patent protection. For example, the Supreme Court of the united States resolved a split
among the circuit courts of appeals regarding antitrust challenges to settlements of patent infringement lawsuits under the hatch-
Waxman act between brand-name drug companies and generic drug companies. the Court rejected the “scope of the patent” test
and ruled that settlements involving “reverse payments” from brand-name drug companies to generic drug companies should be
analyzed  under  the  rule  of  reason.  this  ruling  may  create  uncertainty  and  make  it  more  difficult  to  settle  patent  litigation  if  a
company seeking to manufacture a generic version of one of our products challenges the patents covering that product prior to the
expiration date of those patents.

International patent protection is particularly uncertain and costly, and our involvement in opposition proceedings in foreign
countries may result in the expenditure of substantial sums and management resources.

Biotechnology  and  pharmaceutical  patent  law  outside  the  united  States  is  even  more  uncertain  and  costly  than  in  the
united States and is currently undergoing review and revision in many countries. Further, the laws of some foreign countries may
not protect our intellectual property rights to the same extent as united States laws. For example, certain countries do not grant
patent claims that are directed to the treatment of humans. We have participated, and may in the future participate, in opposition
proceedings to determine the validity of our foreign patents or our competitors’ foreign patents, which could result in substantial
costs  and  diversion  of  our  efforts.  Successful  challenges  to  our  patent  or  other  intellectual  property  rights  through  these
proceedings could result in a loss of rights in the relevant jurisdiction and allow third parties to use our proprietary technologies
without a license from us or our collaborators, which may also result in loss of future royalty payments. in addition, successful
challenges may jeopardize or delay our ability to enter into new collaborations or commercialize potential products, which could
harm our business and results of operations.

RISKS RELATING TO INFORMATION TECHNOLOGY AND DATA PRIVACY

Significant disruptions of information technology systems, breaches of data security, or unauthorized disclosures of sensitive
data or personally identifiable information or individually identifiable health information could adversely affect our business,
and could subject us to liability or reputational damage.

our business  is  increasingly  dependent  on critical,  complex,  and  interdependent  information  technology  (it)  systems,
including internet-based systems, some of which are managed or hosted by third parties, to support business processes as well as
internal and external communications.  the size and complexity of our it systems make us potentially vulnerable to it system
breakdowns, malicious intrusion, and computer viruses, which may result in the impairment of our ability to operate our business
effectively.  in addition, having a significant portion of our employees work remotely due to the CoviD-19 pandemic can strain
our information technology infrastructure, which may affect our ability to operate effectively, may make us more susceptible to
communications disruptions, and expose us to greater cybersecurity risks.

We  are  continuously  evaluating  and,  where  appropriate,  enhancing  our  it  systems  to  address  our  planned  growth,
including to support our planned manufacturing operations. there are inherent costs and risks associated with implementing the
enhancements to our it systems, including potential delays in access to, or errors in, critical business and financial information,
substantial capital expenditures, additional administrative time and operating expenses, retention of sufficiently skilled personnel
to implement and operate the enhanced systems, demands on management time, and costs of delays or difficulties in transitioning
to  the  enhanced  systems,  any  of  which  could  harm  our  business  and  results  of  operations.  in  addition,  the  implementation  of
enhancements  to  our  it  systems  may  not  result  in  productivity  improvements  at  a  level  that  outweighs  the  costs  of
implementation, or at all.  in addition, our systems and the systems of our third-party providers and collaborators are potentially
vulnerable to data security breaches which may expose sensitive

57

table of Contents

data to unauthorized persons or to the public. Such data security breaches could lead to the loss of confidential information, trade
secrets or other intellectual property, could lead to the public exposure of personal information (including personally identifiable
information or individually identifiable health information) of our employees, clinical trial patients, customers, business partners,
and others, could lead to potential identity theft, or could lead to reputational harm.  Data security breaches could also result in
loss of clinical trial data or damage to the integrity of that data. in addition, the increased use of social media by our employees
and  contractors  could  result  in  inadvertent  disclosure  of  sensitive  data  or  personal  information,  including  but  not  limited  to,
confidential information, trade secrets and other intellectual property.

any  such  disruption  or  security  breach,  as  well  as  any  action  by  us  or  our  employees  or  contractors  that  might  be
inconsistent  with  the  rapidly  evolving  data  privacy  and  security  laws  and  regulations  applicable  within  the  united  States  and
elsewhere where we conduct business, could result in enforcement actions by u.S. states, the u.S. Federal government or foreign
governments, liability or sanctions under data privacy laws, including healthcare laws such as hipaa, that protect certain types
of sensitive information, regulatory penalties, other legal proceedings such as but not limited to private litigation, the incurrence
of significant  remediation  costs, disruptions to our development programs, business operations and collaborations,  diversion of
management efforts and damage to our reputation, which could harm our business and operations. Because of the rapidly moving
nature of technology and the increasing sophistication of cybersecurity threats, our measures to prevent, respond to and minimize
such risks may be unsuccessful. 

in addition, the European parliament and the Council of the European union has adopted a comprehensive general data
privacy  regulation,  known  as  the  GDpr,  which  governs  the  collection  and  use  of  personal  data  in  the  European  union.  the
GDpr,  which  is  wide-ranging  in  scope,  imposes  several  requirements  relating  to  the  consent  of  the  individuals  to  whom  the
personal data relates, the information provided to the individuals, the security and confidentiality of the personal data, data breach
notification and the use of third party processors in connection with the processing of the personal data. the GDpr also imposes
strict rules on the transfer of personal data out of the European union to the united States, provides an enforcement authority and
imposes  large  penalties  for  noncompliance,  including  the  potential  for  fines  of  up  to  €20  million  or  4%  of  the  annual  global
revenues  of  the  infringer,  whichever  is  greater.    moreover,  the  European  Court  of  Justice  in  July  2020 invalidated  the  privacy
Shield  framework  that  had  been  in  place  between  the  European  union  and  the  united  States,  which  invalidation  has  created
uncertainty  about  how  data  can  now  be  shared  in  a  compliant  manner.  additionally,  the  California  Consumer  privacy  act
(CCpa) affords  a  private  right  of  action  to  such  consumers  if  certain  data  breaches  result  in  the  loss  or  theft  of  their  personal
information. the GDpr, CCpa and other similar laws or regulations enacted in the united States or other jurisdictions associated
with  the  enhanced  protection  of  certain  types  of  sensitive  data,  including  healthcare  data  or  other  personal  information,  may
increase our costs of doing business, and the differing requirements of these laws and regulations can complicate our compliance
efforts.

Increasing use of social media could give rise to liability, breaches of data security, or reputational damage.

We and our employees are increasingly utilizing  social media tools as a means of communication  both internally  and
externally.  Despite  our  efforts  to  monitor  evolving  social  media  communication  guidelines  and  comply  with  applicable  rules,
there is risk that the use of social media by us or our employees to communicate about our products or business may cause us to
be found in violation of applicable requirements. in addition, our employees may knowingly or inadvertently make use of social
media in ways that may not comply with our social media policy or other legal or contractual requirements, which may give rise
to liability, lead to the loss of trade secrets or other intellectual property, or result in public exposure of personal information of
our employees, clinical trial patients, customers, and others. Furthermore, negative posts or comments about us or our products in
social media could seriously damage our reputation, brand image, and goodwill.

Item 2.  Properties

our  global  headquarters  is  in  Wilmington,  Delaware,  which  is  where  our  principal  drug  discovery  and  development

operations are also located. We own two buildings comprising approximately 344,000 square feet of

table of Contents

laboratory and office space at this site.  in march 2017, we acquired additional adjacent buildings and in 2019, began demolition
of  these  buildings  and  construction  of  a  new  laboratory  and  office  building  totaling  approximately  200,000  square  feet.  the
construction of this building is currently expected to be completed in the second half of 2021. also in october 2019, we entered
into  an  agreement  to  purchase  additional  adjacent  property  for  $50.0  million  to  expand  our  global  headquarters.  under  that
agreement,  closing  of  the  purchase  is  subject  to  certain  standard  closing  conditions,  including  an  initial  diligence  period  and  a
subsequent approval period.

We  lease  approximately  112,000  square  feet  of  office  space  in  Chadds  Ford,  pennsylvania  and  approximately  84,000

square feet of additional laboratory and office space in Wilmington, Delaware.  

We  conduct  our  international  clinical  development  and  commercial  operations  from  our  European  office  in  morges,
Switzerland, our Japanese office in tokyo and our Canadian office in montreal. in July 2018, we purchased a parcel of land in
Yverdon-les-Bains,  Switzerland  upon  which  we  are  building  a  large  molecule  production  facility.  Construction  commenced  in
July 2018 and we currently expect the facility will be operational in the second half of 2021.

Item 3.  Legal Proceedings

From  time  to  time,  we  are  party  to  legal  proceedings  in  the  course  of  our  business.    the  outcome  of  any  such
proceedings, regardless of the merits, is inherently uncertain. legal proceedings, including litigation, government investigations
and enforcement actions, can result in significant costs and occupy significant management resources.  We do not expect any such
current  legal  proceedings  to  have  a  material  adverse  impact  on  our  business  or  financial  condition.  additional  information
regarding our current legal proceedings can be found in note 16 of notes to our consolidated financial statements included in item
8 of this report.

Effects of the COVID-19 Pandemic on Our Business

in December 2019, coronavirus disease of 2019, or CoviD-19, was first reported in Wuhan, China. in march 2020, the
World health organization declared CoviD-19 a pandemic (“the CoviD-19 pandemic”) and certain governments, including the
State  of  Delaware  where  our  primary  offices  and  laboratory  spaces  are  located,  enacted  stay-at-home  orders  and  sweeping
restrictions to travel and business activity were initiated by corporations and governments.

We  took  aggressive,  proactive  actions  early  on  to  protect  the  health  of  our  employees,  and  their  families,  including
voluntarily  requiring  almost  all  personnel  across  our  global  enterprise  to  work  remotely  and  restricting  access  to  our  sites  to
personnel  who  were  required  to  perform  critical  business  continuity  activities.    in  may  2020,  we  initiated  a  return  to  full
laboratory  work  at  our  facilities  in  Wilmington,  Delaware,  as  well  as  a  gradual  return  to  office-based  working,  where  allowed
under local guidelines, at our offices in north america, Europe and asia.

While  we  currently  believe  we  are  well-positioned  to  function  in  a  hybrid  on-site  and  virtual  or  remote  fashion,  the
extent  of  the  CoviD-19  pandemic’s  effect  on  our  operational  and  financial  performance  will  depend  on  future  developments,
including the duration, spread and intensity of the pandemic, protective measures, and the reimposition of protective measures,
implemented  by  governmental  authorities  or  by  us  to  protect  our  employees,  and  effects  of  the  pandemic  and  such  protective
measures  on  our  suppliers,  collaborators,  services  providers  and  healthcare  organizations  serving  patients,  all  of  which  are
uncertain and difficult to predict considering the rapidly evolving landscape. as a result, it is not currently possible to ascertain or
predict the overall long-term impact of the CoviD-19 pandemic on our business.

to date, we have not experienced a material effect on the results of our commercial operations, or our manufacturing
supply  chain,  and  we  have  increased  manufacturing  efforts  of  ruxolitinib  to  respond  to  the  CoviD-19  pandemic  and  to  pre-
clinical and clinical study requests. new patient starts for JaKaFi treatment decreased as a result of shelter in place and other
protective  measures,  and  if  decreases  in  new  patient  starts  occur  in  future  periods,  our  revenues  in  future  periods  could  be
adversely affected. We continue to anticipate that short-term effects may continue to emerge across different aspects of our global
clinical trial programs. For example, while we expect ongoing monitoring of already-enrolled patients to continue, difficulties in
monitoring may result as a consequence of shelter in place orders and other protective measures implemented by governmental
authorities or clinical trial sites.  in addition, new patient recruitment in certain clinical trials has been and may in the future be
impacted, in particular with respect to our earlier stage clinical trials. We also expect the conduct of clinical trials may continue to
vary by disease state and by severity of disease, as well as by geography, as some regions are more adversely impacted. until our
return  to  full  laboratory  work,  our  discovery  laboratories  were  staffed  by  essential  personnel,  and  hence  certain  discovery
programs  experienced  delays.  Still,  we  caution  that  the  duration  and  severity  of  the  continuing  CoviD-19  pandemic  remains
uncertain and we may not yet be able to assess its consequences accurately or fully at this time.

Regulatory Achievements

in april 2020, pEmaZYrE (pemigatinib), a selective fibroblast growth factor receptor (FGFr) inhibitor, was approved
by  the  u.S.  Food  and  Drug  administration  (FDa)  for  the  treatment  of  adults  with  previously  treated,  unresectable  locally
advanced or metastatic cholangiocarcinoma with an FGFr2 fusion or other rearrangement as detected by an FDa-approved test.
pEmaZYrE is the first and only FDa-approved treatment for this indication, which was approved under accelerated approval
based on overall response rate and duration of response. We have retained all rights to pEmaZYrE globally, other than those
granted to innovent Biologics, inc. to develop and commercialize pemigatinib in hematology and oncology in mainland China,
hong Kong, macau and taiwan.

in  may  2020,  under  our  collaboration  agreement  with  novartis  international  pharmaceutical  ltd.,  the  FDa  approved
taBrECta (capmatinib) for the treatment of adult patients with metastatic non-small cell lung cancer (nSClC) whose tumors
have a mutation that leads to mEt exon 14 skipping (mEtex14) as detected by an FDa-approved test. taBrECta is the first
and only treatment approved to specifically target nSClC with this driver mutation and is approved for first-line and previously
treated  patients  regardless  of prior treatment  type. in June 2020, the Japanese  ministry  of health,  labour and Welfare  granted
marketing approval for taBrECta for mEtex14 mutation-positive advanced and/or recurrent unresectable nSClC.

table of Contents

in  July  2020,  under  our  collaboration  and  license  agreement  with  morphoSys  aG,  we  received  FDa  approval  of
monJuvi (tafasitamab-cxix), in  combination with lenalidomide for  the treatment  of  adult patients  with relapsed or  refractory
diffuse large B-cell lymphoma (DlBCl) not otherwise specified, including DlBCl arising from low grade lymphoma, and who
are  not  eligible  for  autologous  stem  cell  transplant.  We  have  rights  to  co-commercialize  tafasitamab  in  the  united  States  with
morphoSys, and we have exclusive development and commercialization rights outside of the united States.

in october 2020, under our collaboration agreement with Eli lilly and Company, the European Commission approved
olumiant  (baricitinib)  for  the  treatment  of  moderate-to-severe  atopic  dermatitis  in  adult  patients  who  are  candidates  for
systemic therapy and in December 2020, Japan’s ministry of health, labor and Welfare (mhlW) approved olumiant for the
treatment of moderate-to-severe atopic dermatitis in adult patients who are candidates for systemic therapy.

License Agreements and Business Relationships

We  establish  business  relationships,  including  collaborative  arrangements  with  other  companies  and  medical  research
institutions  to  assist  in  the  clinical  development  and/or  commercialization  of  certain  of  our  drugs  and  drug  candidates  and  to
provide support for our research programs. We also establish business relationships with other companies and medical research
institutions to acquire products or rights to products and technologies that are complementary to our business. Below summarizes
the significant achievements under our existing collaboration and license agreements and additional agreements we entered into
during the year ended December 31, 2020.

 Novartis

in may  2020, we  recognized  a $25.0 million  development  milestone  and  a $45.0 million  regulatory  milestone  for the
FDa approval of capmatinib as taBrECta. in June 2020, we recognized a $20.0 million regulatory milestone for the mhlW
approval of taBrECta. in December 2020, we recognized a $80.0 million sales milestone for novartis achieving annual net
sales  of  a  JaK  licensed  product  of  $1.2  billion.  Exclusive  of  the  upfront  payment  of  $150.0  million  received  in  2009  and  the
immediate milestone of $60.0 million earned in 2010, we have recognized and received, in the aggregate, $157.0 million for the
achievement of development milestones, $280.0 million for the achievement of regulatory milestones and $200.0 million for the
achievement of sales milestones through December 31, 2020.

Lilly

in  october  2020,  we  recognized  a  $20.0  million  regulatory  milestone  for  the  European  Commission  approval  of
olumiant  and  in  December  2020,  we  recognized  a  $10.0  million  regulatory  milestone  for  the  mhlW  approval  of
olumiant for the treatment of moderate-to-severe atopic dermatitis in adult patients who are candidates for systemic therapy.
Exclusive of the upfront payment of $90.0 million received in 2009, we have recognized and received, in the aggregate, $149.0
million for the achievement of development milestones and $265.0 million for the achievement of regulatory milestones through
December 31, 2020.  

MorphoSys

in January 2020, we entered into a Collaboration and license agreement with morphoSys aG and morphoSys uS inc.,
a  wholly-owned  subsidiary  of  morphoSys  aG,  covering  the  worldwide  development  and  commercialization  of  mor208
(tafasitamab), an investigational Fc engineered monoclonal antibody directed against the target molecule CD19. under the terms
of the agreement, we received exclusive commercialization rights outside of the united States and morphoSys and we have co-
commercialization  rights  in  the  united  States,  with  respect  to  tafasitamab.  We  and  morphoSys  have  agreed  to  co-develop
tafasitamab  and  to  share  development  costs  associated  with  global  and  u.S.-specific  clinical  trials,  with  incyte  responsible  for
55%  of  such  costs  and  morphoSys  responsible  for  45%  of  such  costs.  in  march  2020,  we  paid  morphoSys  an  upfront  non-
refundable  payment  of  $750.0  million  and,  under  a  related  agreement,  purchased  american  Depositary  Shares  (aDSs)  of
morphoSys for an aggregate purchase price of $150.0 million. of the $150.0 million aggregate purchase price paid for the aDSs,
$95.5  million  was  allocated  to  our  stock  purchase  in  morphoSys  and  was  recorded  within  long  term  investments  and  $54.5
million, representing the premium paid on the purchase, was

65

allocated  to  research  and  development  expense.  morphoSys  is  eligible  to  receive  up  to  $740.0  million  in  future  contingent
development  and  regulatory  milestones  and  up  to  $315.0  million  in  commercialization  milestones  as  well  as  tiered  royalties
ranging from the mid-teens to mid-twenties of net sales outside of the united States.  

Nimble

in  September  2020,  we  entered  into  a  collaboration  and  license  agreement  with  nimble  therapeutics,  inc.  under  the
terms  of  this  agreement,  nimble  will  utilize  their  peptide  synthesis,  screening  and  optimization  platform  for  discovery  and
validation  of peptides against  specified  targets.  under the agreement,  nimble is eligible  to receive  up to $8.0 million  in future
contingent  discovery  milestones  and  up  to  $127.0  million  in  future  contingent  development  and  regulatory  milestones.
additionally, in the event of successful commercialization, nimble is eligible to receive up to $130.0 million in future contingent
sales milestones and tiered royalty payments in the low single digits.

additional information regarding our collaboration agreements, including their financial and accounting impact on our

business and results of operations, can be found in note 6 of notes to the Consolidated Financial Statements.

Critical Accounting Policies and Significant Estimates

the  preparation  of  financial  statements  requires  us  to  make  estimates,  assumptions  and  judgments  that  affect  the
reported amounts of assets, liabilities, revenues and expenses, and related disclosures of contingent assets and liabilities. on an
ongoing basis, we evaluate our estimates. We base our estimates on historical experience and various other assumptions that we
believe to be reasonable under the circumstances, the results of which form our basis for making judgments about the carrying
values  of  assets  and  liabilities  that  are  not  readily  apparent  from  other  sources.  actual  results  may  differ  from  those  estimates
under  different  assumptions  or  conditions.  We  believe  the  following  critical  accounting  policies  reflect  the  more  significant
judgments and estimates used in the preparation of our consolidated financial statements. See note 1 of notes to the Consolidated
Financial Statements for a complete list of our significant accounting policies.

Revenue Recognition. We recognize revenue only when we have satisfied a performance obligation through transferring
control  of  the  promised  good  or  service  to  a  customer  in  an  amount  that  reflects  the  consideration  we  expect  to  receive  in
exchange for those goods or services. We apply the following five-step model in order to determine this amount: (i) identification
of the promised goods or services in the contract; (ii) determination of whether the promised goods or services are performance
obligations, including whether they are distinct in the context of the contract; (iii) measurement of the transaction price, including
the constraint on variable consideration; (iv) allocation of the transaction price to the performance obligations; and (v) recognition
of  revenue  when (or as)  the  Company satisfies  each  performance  obligation,  which for  the  Company  is  generally  at  a point  in
time.  We  also  assess  collectability  based  primarily  on  the  customer’s  payment  history  and  on  the  creditworthiness  of  the
customer.

Product Revenues

our  product  revenues  consist  of  u.S.  sales  of  JaKaFi  and  pEmaZYrE  and  European  sales  of  iCluSiG.    product
revenues are recognized once we satisfy the performance obligation at a point in time under the revenue recognition criteria as
described above. We recognize revenues for product received by our customers net of allowances for customer credits, including
estimated rebates, chargebacks, discounts, returns, distribution service fees, patient assistance programs, and government rebates,
such  as  medicare  part  D coverage  gap  reimbursements  in  the  united  States.  these  sales  allowances  and  accruals  are  recorded
based on estimates which are described  in detail below.  Estimates are assessed as of the end of each reporting period and are
updated to reflect current information.  We believe that our sales allowances and accruals are reasonable and appropriate based on
current facts and circumstances. Changes in estimates for sales allowances and accruals for product shipped in prior periods have
resulted in immaterial adjustments to product revenues.

Customer Credits: our  customers  are  offered  various  forms  of  consideration,  including  allowances,  service  fees  and
prompt  payment  discounts.  We  expect  our  customers  will  earn  prompt  payment  discounts  and,  therefore,  we  deduct  the  full
amount of these discounts from total product sales when revenues are recognized. Service fees are also deducted

66

table of Contents

from total product sales as they are earned.

Rebates  and  Discounts:   We  accrue  rebates  for  mandated  discounts  under  the  medicaid  Drug  rebate  program  in  the
united  States  and  mandated  discounts  in  Europe  in  markets  where  government-sponsored  healthcare  systems  are  the  primary
payers for healthcare. these accruals are based on statutory discount rates and expected utilization as well as historical data we
have  accumulated  since  product  launch.  our  estimates  for  expected  utilization  of  rebates  are  based  on  data  received  from  our
customers. rebates are generally invoiced and paid in arrears so that the accrual balance consists of an estimate of the amount
expected  to  be  incurred  for  the  current  quarter’s  activity,  plus  an  accrual  balance  for  known  prior  quarters’  unpaid  rebates.  if
actual future rebates vary from estimates, we may need to adjust prior period accruals, which would affect revenue in the period
of adjustment.

Chargebacks:  Chargebacks  are  discounts  that  occur  when  certain  contracted  customers  purchase  directly  from  our
wholesalers at a discounted price. the wholesalers, in turn, charges back to us the difference between the price initially paid by
the  wholesalers  and  the  discounted  price  paid  by  the  contracted  customers.  in  addition  to  actual  chargebacks  received,  we
maintain  an  accrual  for  chargebacks  based  on  the  estimated  contractual  discounts  on  the  inventory  levels  on  hand  in  our
distribution channel.  if actual future chargebacks vary from these estimates, we may need to adjust prior period accruals, which
would affect revenue in the period of adjustment.

Medicare Part D Coverage Gap: medicare part D prescription drug benefit mandates manufacturers to fund 70% of the
medicare part D insurance coverage gap for prescription drugs sold to eligible patients. our estimates for the expected medicare
part D coverage gap are based on historical invoices received and in part from data received from our customers. Funding of the
coverage gap is generally invoiced and paid in arrears so that the accrual balance consists of an estimate of the amount expected
to be incurred for the current quarter’s activity, plus an accrual balance for known prior quarters. if actual future funding varies
from  estimates,  we  may  need  to  adjust  prior  period  accruals,  which  would  affect  revenue  in  the  period  of  adjustment.
additionally, beginning in January 2020, the amount of spending required by eligible patients in the medicare part D insurance
coverage gap increased 30% due to the expiration of a provision in the patient protection and affordable Care act, which now
results in a change in the true out of pocket (troop) calculation methodology. the methodological change has resulted in an
increase  in  required  spending  by  patients  and,  in  turn,  an  increase  in  manufacturers’  contributions  on  behalf  of  patients  in  the
medicare part D insurance coverage gap.

Co-payment Assistance:  patients who have commercial insurance and meet certain eligibility requirements may receive
co-payment  assistance.  We  accrue  a  liability  for  co-payment  assistance  based  on  actual  program  participation  and  estimates  of
program redemption using data provided by third-party administrators.

Product Royalty Revenues

royalty revenues on commercial sales for JaKavi and taBrECta by novartis are estimated based on information
provided  by  novartis.  royalty  revenues  on  commercial  sales  for  olumiant  by  lilly  are  estimated  based  on  information
provided by lilly. We exercise judgment in determining whether the information provided is sufficiently reliable for us to base
our royalty revenue recognition thereon. if actual royalties vary from estimates, we may need to adjust the prior period, which
would affect royalty revenue and receivable in the period of adjustment.

Milestone and Contract Revenues

at the inception of a contract, we determine the transaction price, in addition to any upfront payment, by estimating the
amount  of  variable  consideration,  including  milestone  payments,  at  the  outset  of  the  contract  utilizing  the  most  likely  amount
method.  our  contractual  milestones  typically  relate  to  the  achievement  of  pre-specified  development,  regulatory  and
commercialization events outside of our control, such as regulatory approval of a compound, first patient dosing or achievement
of sales-based thresholds. We include milestones in the transaction price only to the extent that it is probable that a significant
reversal  in  the  amount  of  cumulative  revenue  recognized  will  not  occur  when  the  uncertainty  associated  with  the  milestone  is
subsequently resolved. Given the high level of uncertainty of achievement, variable consideration associated with milestones are
fully constrained until confirmation of the satisfaction or completion of the milestone by the third-party. We review our estimate
of the transaction price each period, and make revisions to such estimates as necessary.

Stock Compensation.  Share-based payment transactions with employees, which include stock options, restricted stock
units (rSus) and performance shares (pSus), are recognized as compensation expense over the requisite service period based on
their  estimated  fair  values  at  the  date  of  grant  as  well  as  expected  forfeiture  rates  based  on  actual  experience.  the  stock
compensation process requires significant judgment and the use of estimates, particularly surrounding Black-Scholes assumptions
such  as  stock  price  volatility  over  the  option  term  and  expected  option  lives,  as  well  as  expected  forfeiture  rates  and  the
probability of pSus vesting. the fair value of stock options, which are subject to graded vesting, are recognized as compensation
expense over the requisite service period using the accelerated attribution method.  the fair value of rSus that are subject to cliff
vesting are recognized as compensation expense over the requisite service period using the straight-line attribution method, and
the fair value of rSus that are subject to graded vesting are recognized as compensation expense over the requisite service period
using the accelerated attribution method.  the fair value of pSus are recognized as compensation expense beginning at the time
in  which  the  performance  conditions  are  deemed  probable  of  achievement.  We  assess  the  probability  of  achievement  of
performance  conditions,  including  projected  product  revenues  and  clinical  development  milestones,  as  of  the  end  of  each
reporting period. once a performance condition is considered probable, we record compensation expense based on the portion of
the  service  period  elapsed  to  date  with  respect  to  that  award,  with  a  cumulative  catch-up,  net  of  estimated  forfeitures,  and
recognize  any  remaining  compensation  expense,  if  any,  over  the  remaining  requisite  service  period  using  the  straight-line
attribution method for pSus that are subject to cliff vesting and using the accelerated attribution method for pSus that are subject
to graded vesting.

Income Taxes. We  account  for  income  taxes  using  an  asset  and  liability  approach  to  financial  accounting  for  income
taxes.    under  this  method,  deferred  tax  assets  and  liabilities  are  determined  based  on  the  difference  between  the  financial
statement  carrying  amounts  and  tax  bases of assets  and liabilities  using  enacted  tax rates  in effect  for years  in which the basis
differences are expected to reverse. We periodically assess the likelihood of the realization of deferred tax assets, and reduce the
carrying  amount  of  these  deferred  tax  assets  to  an  amount  that  is  considered  to  be  more-likely-than-not  to  be  realizable.  our
assessment considers recent cumulative earnings experience, projections of future taxable income (losses) and ongoing prudent
and  feasible  tax  planning  strategies.    When  performing  our  assessment  on  projections  of  future  taxable  income  (losses),  we
consider factors such as the likelihood of regulatory approval and commercial success of products currently under development,
among other factors.   Significant judgment is required in making this assessment and, to the extent that a reversal of any portion
of  our  valuation  allowance  against  our  deferred  tax  assets  is  deemed  appropriate,  a  tax  benefit  will  be  recognized  against  our
income tax provision in the period of such reversal.

We recognize the tax benefit from an uncertain tax position only if it is more-likely-than-not that the position will be
sustained upon examination by the taxing authorities, including resolutions of any related appeals or litigation processes, based on
the technical merits of the position. the tax benefit that is recorded for these positions is measured at the largest amount of benefit
that is greater than 50 percent likely of being realized upon ultimate settlement. We adjust the level of the liability to reflect any
subsequent changes in the relevant facts surrounding the uncertain positions. any interest and penalties on uncertain tax positions
are included within the tax provision.

We record estimates and prepare and file tax returns in various jurisdictions across the united States, Canada, Europe,
and asia based upon our interpretation of local tax laws and regulations.  While we exercise significant judgment when applying
complex  tax  laws  and  regulations  in  these  various  taxing  jurisdictions,  many  of  our  tax  returns  are  open  to  audit,  and  may  be
subject to future tax, interest, and penalty assessments.

We  believe  our  estimates  for  the  valuation  allowances  against  certain  deferred  tax  assets  and  the  amount  of  benefits
associated with uncertain tax positions recognized in our financial statements are appropriate based upon our assessment of the
factors mentioned above.  

Acquisition-related  contingent  consideration.    acquisition-related  contingent  consideration,  which  consists  of  our
future royalty obligations to ariaD/takeda, was recorded on the acquisition date at the estimated fair value of the obligation, in
accordance  with the acquisition method of accounting.  the fair  value of the contingent  consideration was determined using an
income  approach  based  on  estimated  iCluSiG  revenues  in  the  European  union  and  other  countries.  as  the  fair  value
measurement is based on significant inputs that are unobservable in the market, this represents a level 3 measurement.

68

table of Contents

the fair value of the acquisition-related contingent consideration is remeasured each reporting period, with changes in
fair  value  recorded  in  the  consolidated  statements  of  operations.  the  assumptions  used  to  determine  the  fair  value  of  the
acquisition-related contingent consideration include projected iCluSiG revenues and a discount rate which, require significant
judgement and are analyzed on a quarterly basis. While we use the best available information to prepare our projected iCluSiG
revenues and discount rate assumptions, actual iCluSiG revenues and/or market conditions could differ significantly.  Changes
to  one  or  multiple  inputs  could  have  a  material  impact  on  the  amount  of  acquisition-related  contingent  consideration  expense
recorded during the reporting period.

the increase in JaKaFi product revenues from 2019 to 2020 was comprised of a volume increase of $220.4 million and
a  price  increase  of  $32.5  million.  our product  revenues  may  fluctuate  from  period  to  period  due  to  our  customers’  purchasing
patterns over the course of a year, including as a result of increased inventory building by customers in advance of expected or
announced  price  increases.  product  revenues  are  recorded  net  of  estimated  product  returns,  pricing  discounts  including  rebates
offered  pursuant  to  mandatory  federal  and  state  government  programs  and  chargebacks,  prompt  pay  discounts  and  distribution
fees  and  co-pay  assistance.  our  revenue  recognition  policies  require  estimates  of  the  aforementioned  sales  allowances  each

Government rebates and chargebacks are the most significant component of our sales allowances. increases in certain
government  reimbursement  rates  are  limited  to  a  measure  of  inflation,  and  when  the  price  of  a  drug  increases  faster  than  this
measure of inflation it will result in a penalty adjustment factor that causes a larger sales allowance to those government related
entities. We expect government rebates and chargebacks as a percentage of our gross product sales will continue to increase in
connection with any future product price increases greater than the rate of inflation, and any such increase in these government
rebates  and  chargebacks  will  have  a  negative  impact  on  our  reported  product  revenues,  net.  We  adjust  our  estimates  for
government rebates and chargebacks based on new information regarding actual rebates as it becomes available.  Claims by third-
party payors for rebates and chargebacks are frequently submitted after the period in which the related sales occurred, which may
result  in  adjustments  to  prior  period  accrual  balances  in  the  period  in  which  the  new  information  becomes  available.  We  also
adjust our allowance for product returns based on new information regarding actual returns as it becomes available.  

We expect our sales allowances to fluctuate from quarter to quarter as a result of the medicare part D Coverage Gap, the
volume of purchases eligible for government mandated discounts and rebates as well as changes in discount percentages which
are impacted by potential future price increases, rate of inflation, and other factors.

product  royalty  revenues  on  commercial  sales  of  JaKavi  and  taBrECta  by  novartis  are  based  on  net  sales  of
licensed products in licensed territories as provided by novartis. product royalty revenues on commercial sales of olumiant
by lilly are based on net sales of licensed products in licensed territories as provided by lilly.

our milestone and contract revenues were $205.0 million and $77.5 million for the years ended December 31, 2020 and
2019,  respectively.  During  the  year  ended  December  31,  2020,  our  milestone  and  contract  revenues  were  derived  from  a  $5.0
million milestone under the innovent agreement, $170.0 million in milestones under the novartis agreement and $30.0 million in
milestones  under  the  lilly  agreement.  During  the  year  ended  December  31,  2019,  our  milestone  and  contract  revenues  were
derived from a $40.0 million upfront payment and a $20.0 million milestone under the innovent agreement and a $17.5 million
upfront payment under the Zai lab agreement.

Cost of product revenues includes all JaKaFi, iCluSiG and pEmaZYrE related product costs, employee personnel
costs,  including  stock  compensation,  for  those  employees  dedicated  to  the  production  of  our  commercial  products,  low  single-
digit royalties to novartis on all sales of JaKaFi in the united States and amortization of our licensed intellectual property rights
for iCluSiG using the straight-line method over the estimated useful life of 12.5 years. Cost of product revenues increased from
2019 to 2020 due primarily to increased royalties to novartis on all JaKaFi sales in the united States.

We  account  for  research  and  development  costs  by  natural  expense  line  and  not  costs  by  project.  Salary  and  benefits
related  expense  increased  from  2019  to  2020  due  primarily  to  increased  development  headcount  to  sustain  our  development
pipeline. Stock compensation expense may fluctuate from period to period based on the number of awards granted, stock price
volatility and expected award lives, as well as expected award forfeiture rates which are used to value equity-based compensation.

the  increase  in  clinical  research  and  outside  services  expense  from  2019  to  2020  was  primarily  due  to  upfront
consideration of $804.5 million related to our collaborative agreement with morphoSys, the cost of purchasing an FDa priority
review voucher for $120.0 million, which we used in connection with our submission seeking FDa approval of ruxolitinib cream
for the treatment of atopic dermatitis, and milestones achieved under our collaboration and license agreement with macroGenics
of  $40.0  million.  research  and  development  expenses  include  upfront  and  milestone  expenses  related  to  our  collaborative
agreements  of  $976.1  million  and  $27.8  million  for  the  years  ended  December  31,  2020  and  2019,  respectively.  research  and
development expenses for the years ended December 31, 2020 and 2019 were net of $8.5 million and $15.1 million, respectively,
of costs reimbursed by our collaborative partners.

in  addition  to  one-time  expenses  resulting  from  upfront  fees  in  connection  with  the  entry  into  any  new  or  amended
collaboration agreements and payment of milestones under those agreements, research and development expenses may fluctuate
from period to period depending upon the stage of certain projects and the level of pre-clinical and clinical trial related activities.
many factors can affect the cost and timing of our clinical trials, including requests by regulatory agencies for more information,
inconclusive results requiring additional clinical trials, slow patient enrollment, adverse side effects among patients, insufficient
supplies for our clinical trials, timing of drug supply, including api, and real or perceived lack of effectiveness or safety of our
investigational  drugs  in  our  clinical  trials.  in  addition,  the  development  of  all  of  our  products  will  be  subject  to  extensive
governmental  regulation.  these  factors  make  it  difficult  for  us  to  predict  the  timing  and  costs  of  the  further  development  and
approval of our products.

Salary and benefits related expense increased from 2019 to 2020 due primarily to increased headcount. this increased
headcount  was  due  primarily  to  the  ongoing  commercialization  efforts  related  to  JaKaFi  for  intermediate  or  high-risk
myelofibrosis,  uncontrolled  polycythemia  vera  and  GvhD  as  well  as  increased  headcount  related  to  our  European  operations.
Stock compensation expense may fluctuate from period to period based on the number of awards granted, stock price volatility
and  expected  award  lives,  as  well  as  expected  award  forfeiture  rates  which  are  used  to  value  equity-based  compensation.  the
increase in other contract services and outside costs was primarily due to an increase in sales and marketing spend to support the
commercialization  of  pemazyre  in  the  united  States  and  to  prepare  for  the  potential  launch  of  ruxolitinib  cream  in  the  united
States and pemigatinib and tafasitamab in the European union.

Change in fair value of acquisition-related contingent consideration

acquisition-related  contingent  consideration,  which  consists  of  our  future  royalty  obligations  to  ariaD/takeda,  was
recorded  on the acquisition  date, June 1, 2016, at the estimated  fair value of the obligation,  in accordance  with the acquisition
method of accounting. the fair value of the acquisition-related contingent consideration is remeasured quarterly.  the change in
fair value of the acquisition-related contingent consideration for the years ended December 31, 2020 and 2019 was expense of
$23.4  million  and  $19.7  million,  respectively,  which  is  recorded  in  change  in  fair  value  of  acquisition-related  contingent
consideration on the consolidated statements of operations. the change in fair value of the contingent consideration for the years
ended December 31, 2020 and 2019 was due primarily to the passage of time as there were no other significant changes in the key
assumptions during the periods.

Collaboration loss sharing

under  the  collaboration  and  license  agreement  with  morphoSys,  which  was  executed  in  march  2020,  we  and
morphoSys are both responsible for the commercialization efforts of tafasitamab in the united States and will share equally the
profits and losses from the co-commercialization efforts. For the year ended December 31, 2020, our 50% share of the costs for
tafasitamab was $42.8 million, as recorded in collaboration loss sharing on the consolidated statement of operations.

Other income (expense)

Other  income  (expense),  net.   other  income  (expense),  net,  for  the  years  ended  December  31,  2020  and  2019  was
$23.2  million  and  $52.2  million,  respectively.  the  decrease  in  other  income  (expense),  net  primarily  relates  to  a  decrease  in
interest income earned from our investments in marketable securities and money market accounts.

Interest expense.  interest expense for the years ended December 31, 2020 and 2019, was $2.2 million and $1.9 million,
respectively. included in interest expense for the years ended December 31, 2020 and 2019 was $0.7 million and $0.9 million,
respectively, of non-cash charges to amortize the discounts on our convertible senior notes that matured in november 2020 and
approximately $1.2 million and $0.6 million, respectively, of interest expense on our finance lease liabilities.

Provision for income taxes. the provision for income taxes for the years ended December 31, 2020 and 2019 was $63.5
million and $39.9 million, respectively.  the increase in provision for income taxes primarily relates to increased federal and state
tax liabilities that are not fully sheltered by net operating losses or research and development tax credit carryforwards.

Due to historical net losses, we had an accumulated deficit of $1.7 billion as of December 31, 2020. We have funded our
research  and  development  operations  through  sales  of  equity  securities,  the  issuance  of  convertible  notes,  cash  received  from
customers for the sale of our commercialized products, and collaborative arrangements. at December 31, 2020, we had available
cash, cash equivalents and marketable securities of $1.8 billion. our cash and marketable securities balances are held in a variety
of  interest-bearing  instruments,  including  money  market  accounts,  and  u.S.  government  debt  securities.  available  cash  is
invested  in  accordance  with  our  investment  policy’s  primary  objectives  of  liquidity,  safety  of  principal  and  diversity  of
investments.

Cash  (used  in)  provided  by  operating  activities. the  $835.3  million  decrease  in  cash  provided  by  operating  activities
from  2019  to  2020  was  due  primarily  to  cash  outflows  related  to  our  collaboration  and  license  agreements,  in  particular,  the
$804.5 million upfront consideration paid to morphoSys, and, to a lesser extent, changes in working capital.

Cash  used  in  investing  activities.   our  investing  activities,  other  than  purchases,  sales  and  maturities  of  marketable
securities, have consisted predominantly of capital expenditures and purchases of long term investments. During 2020, net cash
used  in  investing  activities  was  $269.0  million,  which  represents  purchase  of  long  term  equity  investments  of  $95.5  million,
purchases  of  marketable  securities  of  $516.9  million  and  capital  expenditures  of  $187.4  million,  offset  in  part  by  the  sale  and
maturity of marketable securities of $513.5 million and the sale of long term investment of $17.3 million. During 2019, net cash
used in investing activities was $87.5 million, which represents purchases of marketable securities

of  $374.8  million  and  capital  expenditures  of  $78.1  million,  offset  in  part  by  the  sale  and  maturity  of  marketable  securities  of
$365.4 million. 

Cash  provided  by  financing  activities.   During  2020  and  2019,  net  cash  provided  by  financing  activities  was
$71.7  million  and  $45.7  million,  respectively,  consisting  primarily  of  proceeds  from  the  issuance  of  common  stock  under  our
stock plans, offset in part by cash paid to ariaD/takeda for contingent consideration.

in  october  2019,  we  entered  into  an  agreement  with  Wilmington  Friends  School  inc.,  to  purchase  property  for  $50.0
million to expand our global headquarters.  under that agreement,  closing of the purchase is subject to certain standard closing
conditions, including an initial diligence period and a subsequent approval period.

We believe that our cash flow from operations, together with our cash, cash equivalents and marketable securities, will
be adequate to satisfy our capital needs for the foreseeable future. our cash requirements depend on numerous factors, including
our  expenditures  in  connection  with  our  drug  discovery  and  development  programs  and  commercialization  operations;
expenditures in connection with litigation or other legal proceedings; costs for future facility requirements; and expenditures for
future strategic equity investments or potential acquisitions. We have entered into and may in the future seek to license additional
rights relating to technologies or drug development candidates in connection with our drug discovery and development programs.
under these licenses, we may be required to pay upfront fees, milestone payments, and royalties on sales of future products. Due
to the contingent nature of these future payments, they are not included in the contractual obligations table above; however, are
discussed in detail in note 6 of notes to our consolidated financial statements included in item 8 of this report.

to  the  extent  we  seek  to  augment  our  existing  cash  resources  and  cash  flow  from  operations  to  satisfy  our  cash
requirements for future acquisitions or other strategic purposes, we expect that additional funding can be obtained through equity
or debt financings or from other sources. the sale of equity or additional convertible debt securities in the future may be dilutive
to our stockholders, and may provide for rights, preferences or privileges senior to those of our holders of common stock. Debt
financing arrangements may require us to pledge certain assets or enter into covenants that could restrict our operations or our
ability to incur further indebtedness.

 Off-Balance Sheet Arrangements

We have no off-balance sheet arrangements other than those that are discussed above.

Item 7A.  Quantitative and Qualitative Disclosures About Market Risk

our investments  in marketable  securities,  which are  composed primarily  of u.S. government  securities,  are subject  to
default,  changes  in  credit  rating  and  changes  in  market  value.  these  investments  are  also  subject  to  interest  rate  risk  and  will
decrease in value if market interest rates increase. as of December 31, 2020, marketable securities were $288.4 million. Due to
the  nature  of  these  investments,  if  market  interest  rates  were  to  increase  immediately  and  uniformly  by  10%  from  levels  as  of
December 31, 2020, the decline in fair value would not be material.

Report of Independent Registered Public Accounting Firm

to the Stockholders and the Board of Directors of incyte Corporation

Opinion on the Financial Statements 

We have audited the accompanying consolidated balance sheets of incyte Corporation (the Company) as of December 31, 2020 
and 2019, the related consolidated statements of operations, comprehensive income (loss), stockholders’ equity and cash flows for 
each of the three years in the period ended December 31, 2020, 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, 2020 and 2019, and the results of its operations and its cash flows for each of the three 
years in the period ended December 31, 2020, 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, 2020, 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 9, 2021 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 Matters

the critical audit matters communicated below are matters arising from the current period audit of the financial statements that
were communicated or required to be communicated to the audit committee and that: (1) relate to accounts or disclosures that are
material to the financial statements and (2) involved our especially challenging, subjective or complex judgments. the
communication of critical audit matters does not alter in any way our opinion on the consolidated financial statements, taken as a
whole, and we are not, by communicating the critical audit matters below, providing separate opinions on the critical audit
matters or on the accounts or disclosures to which they relate.

Allowances for rebates, discounts and chargebacks owed to governmental entities

Description of the
Matter

as discussed in note 1 to the consolidated financial statements, the Company recognizes revenues for
product received by its customers net of allowances for customer credits, including estimated rebates,
chargebacks, discounts, returns, distribution service fees, patient assistance programs, and government
rebates. liabilities related to sales allowances are presented within accrued and other current liabilities on
the consolidated balance sheet and totaled $73.2 million as of December 31, 2020.

auditing the allowances for rebates, discounts and chargebacks owed to governmental entities was
complex and highly judgmental due to the significant estimation uncertainty involved in management’s
assumptions, including the levels of expected utilization of these rebates, discounts

76

table of Contents

and chargebacks based on the amount of drugs sold to eligible patients, as well as the complexity of the
government mandated calculations. the allowances for rebates, discounts and chargebacks owed to
governmental entities are sensitive to these significant assumptions and calculations.

How We
Addressed the
Matter in Our
Audit

We obtained an understanding, evaluated the design and tested the operating effectiveness of controls over
management’s review of the allowances for rebates, discounts and chargebacks owed to governmental
entities. For example, we tested controls over management’s review of the significant assumptions, such
as the utilization of these rebates, discounts and chargebacks as well as controls over management’s
review of the application of the government mandated calculations.

to test the allowances for rebates, discounts, and chargebacks owed to governmental entities, we
performed audit procedures that included, among others, evaluating the methodologies used and testing
the significant assumptions discussed above. We compared the significant assumptions used by
management to historical trends, evaluated the change in the accruals from prior periods, and assessed the
historical accuracy of management’s estimates against actual results. We also tested the completeness and
accuracy of the underlying data used in the Company’s calculations through reconciliation to third-party
invoices, claims data and actual cash payments. in addition, we involved our governmental pricing
specialists to assist in evaluating management’s methodology and calculations used to measure certain
estimated rebates, discounts and chargebacks.

Valuation of acquisition-related contingent consideration liability

Description of the
Matter

as discussed in note 3 to the consolidated financial statements, the Company’s acquisition-related
contingent consideration liability, which consists of certain future royalty obligations on future net sales of
iCluSiG, is remeasured to its estimated fair value each reporting period, with changes in fair value
recorded in the consolidated statements of operations. as of December 31, 2020, the acquisition-related
contingent consideration liability was $266.0 million.

auditing the valuation of the acquisition-related contingent consideration liability was complex and highly
judgmental due to the significant estimation required in determining the fair value. in particular, the fair
value estimate was sensitive to significant assumptions such as the weighted average cost of capital and
projected future iCluSiG revenues, which are affected by expectations about future industry, market or
economic conditions, and are forward-looking and inherently uncertain.

How We
Addressed the
Matter in Our
Audit

We obtained an understanding, evaluated the design and tested the operating effectiveness of controls over 
the Company’s valuation of the acquisition-related contingent consideration liability. For example, we 
tested the Company's controls over management’s review of the valuation model, including controls over 
the significant assumptions utilized in the calculation, such as the weighted average cost of capital and the 
projected future iCluSiG revenues. 

to test the estimated fair value of the acquisition-related contingent consideration liability, we performed
audit procedures that included, among others, assessing the terms of the arrangement, evaluating the
methodology used, and testing the significant assumptions discussed above used by the Company in its
analysis. We involved our valuation specialists to assist in the evaluation of the significant assumptions
and methodology used by the Company. We also compared the significant assumptions to current
industry, market and economic trends and to the Company's budgets and forecasts. in addition, we
assessed the historical accuracy of management’s estimates against actual performance.

INCYTE CORPORATION
NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS

Note 1. Organization and Summary of Significant Accounting Policies

Organization  and  Business.   incyte  Corporation  (including  its  subsidiaries,  “incyte,”  “we,”  “us,”  or  “our”)  is  a
biopharmaceutical  company  focused  on  developing  and  commercializing  proprietary  therapeutics.  our  portfolio  includes
compounds  in  various  stages,  ranging  from  preclinical  to  late  stage  development,  and  commercialized  products  JaKaFi®
(ruxolitinib),
 pEmaZYrE®  (pemigatinib)  and  monJuvi®  (tafasitamab-cxix)  which  is  co-
commercialized. our operations are treated as one operating segment.

 iCluSiG®  (ponatinib),

Principles of Consolidation.  the consolidated financial statements include the accounts of incyte Corporation and our

wholly owned subsidiaries. all inter-company accounts, transactions, and profits have been eliminated in consolidation.

Foreign Currency Translation. operations in non-u.S. entities are recorded in the functional currency of each entity. For
financial  reporting  purposes,  the  functional  currency  of  an  entity  is  determined  by  a  review  of  the  source  of  an  entity's  most
predominant  cash  flows.  the  results  of  operations  for  any  non-u.S.  dollar  functional  currency  entities  are  translated  from
functional  currencies  into  u.S.  dollars  using  the  average  currency  rate  during  each  month.  assets  and  liabilities  are  translated
using currency rates at the end of the period. adjustments resulting from translating the financial statements of our foreign entities
that  use  their  local  currency  as  the  functional  currency  into  u.S.  dollars  are  reflected  as  a  component  of  other  comprehensive
income  (loss).  transaction  gains  and  losses  are  recorded  in  other  income  (expense),  net,  in  the  consolidated  statements  of
operations.

Use of Estimates.  the preparation of financial statements in conformity with accounting principles generally accepted in
the  united  States  requires  management  to  make  estimates  and  assumptions  that  affect  the  amounts  reported  in  the  financial
statements and accompanying notes. actual results could differ from those estimates.

Concentrations  of  Credit  Risk.   Cash,  cash  equivalents,  marketable  securities,  and  trade  receivables  are  financial
instruments  which  potentially  subject  us  to  concentrations  of  credit  risk.  the  estimated  fair  value  of  financial  instruments
approximates the carrying value based on available market information. By policy, we invest our excess available funds primarily
in u.S. government debt securities which are securities issued or guaranteed by the u.S. government and money market funds that
meet certain guidelines, which limits exposure to potential credit losses. our receivables mainly relate to our product sales and
collaborative  agreements  with  pharmaceutical  companies.  We  have  not  experienced  any  significant  credit  losses  on  cash,  cash
equivalents, marketable securities, or trade receivables to date and do not require collateral on receivables.

Current Expected Credit Losses.  Effective January 1, 2020, financial assets measured at amortized cost are assessed for
future expected credit losses under guidance within aSC 326, Financial instruments – Credit losses, to determine if application
of an expected credit losses reserve is necessary. on a quarterly basis, receivables that resulted from revenue transactions within
the scope of aSC 606 and recognized on an amortized cost basis are reviewed on a customer-level basis to analyze expectations
of  future  collections  based  upon  past  history  of  collections,  payment,  aging  of  receivables  and  viability  of  the  customer  to
continue  payment,  as  well  as  estimates  of  future  economic  conditions.  receivables  generally  consist  of  two  types:  receivables
from  collaborative  agreements,  including  milestones,  reimbursements  for  agreed-upon  activities  and  sales  royalties;  and
receivables  from  customer  product  sales.  Collaborative  agreement  receivables  are  closely  monitored  relationships  with  select,
reputable industry peers. Collection of receivables is assessed within each collaborative partnership on a quarterly basis, including
evaluation  of  each  entity’s  credit  quality,  financial  health  and  past  history  of  payment.  Customer  product  sales  receivables  are
independently evaluated on a monthly basis, on which unusual items or aged receivables are closely monitored for signs of credit
deterioration,  or  indications  of  payment  refusal.  Customer  product  sales  are  with  specialty  pharmaceutical  distributors,
wholesalers,  and  certain  public  and  private  institutions,  some  of  which  whose  financial  obligations  are  funded  by  various
government agencies.

table of Contents

Cash  and  Cash  Equivalents.   Cash  and  cash  equivalents  are  held  in  banks  or  in  custodial  accounts  with  banks.  Cash
equivalents are defined as all liquid investments and money market funds with maturity from date of purchase of 90 days or less
that are readily convertible into cash.

Marketable Securities—Available-for-Sale.  our marketable  securities  consist of investments  in u.S. government  debt
securities that are classified as available-for-sale. available-for-sale securities are carried at fair value, based on quoted market
prices  and  observable  inputs,  with  unrealized  gains  and  losses,  net  of  tax,  reported  as  a  separate  component  of  stockholders’
equity.  We  classify  marketable  securities  that  are  available  for  use  in  current  operations  as  current  assets  on  the  consolidated
balance sheets. realized gains and losses and declines in value judged to be other than temporary for available-for-sale securities
are included in other income (expense), net on the consolidated statements of operations. the cost of securities sold is based on
the specific identification method.

Accounts Receivable.  as of December 31, 2020 and 2019, we had no allowance for doubtful accounts. We provide an
allowance  for  doubtful  accounts  based  on  management’s  assessment  of  the  collectability  of  specific  customer  accounts  and
includes consideration of the credit worthiness and financial condition of those customers, aging of such receivables, history of
collectability with the customer and the general economic environment. We record an allowance to reduce the receivables to the
amount that is reasonably believed to be collectible.

Inventory.   inventories  are  determined  at  the  lower  of  cost  and  net  realizable  value  with  cost  determined  under  the

specific identification method and may consist of raw materials, work in process and finished goods.

We began capitalizing pEmaZYrE inventory after FDa approval in april 2020 as the related costs were expected to be
recoverable through the commercialization of the product.  Costs incurred prior to FDa approval have been recorded as research
and development expense in our statements of operations. as a result, cost of product revenues for the next 48 months will reflect
a lower average per unit cost of materials.

JaKaFi, iCluSiG and pEmaZYrE raw materials and work-in-process inventory are not subject to expiration and the
shelf  life  of  finished  goods  inventory  is  36  months  from  the  start  of  manufacturing  of  the  finished  goods.  We  evaluate  for
potential excess inventory by analyzing current and future product demand relative to the remaining product shelf life. We build
demand forecasts by considering factors such as, but not limited to, overall market potential, market share, market acceptance and
patient usage. We classify inventory as current on the consolidated balance sheets when we expect inventory to be consumed for
commercial use within the next twelve months.

Variable  Interest  Entities. We  perform  an  initial  and  ongoing  evaluation  of  the  entities  with  which  we  have  variable
interests, such as equity ownership, in order to identify entities (i) that do not have sufficient equity investment at risk to permit
the entity to finance its activities without additional subordinated financial support or (ii) in which the equity investors lack an
essential characteristic of a controlling financial interest as variable interest entities (“viE” or “viEs”). if an entity is identified as
a  viE,  we  perform  an  assessment  to  determine  whether  we  have  both  (i)  the  power  to  direct  activities  that  most  significantly
impact the viE’s economic performance and (ii) have the obligation to absorb losses from or the right to receive benefits of the
viE  that  could  potentially  be  significant  to  the  viE.  if  both  of  these  criteria  are  satisfied,  we  are  identified  as  the  primary
beneficiary of the viE. as of December 31, 2020, there were no entities in which we held a variable interest which we determined
to be viEs.

Long  Term  Investments. our  long  term  investments  consist  of  equity  investments  in  common  stock  of  publicly-held
companies with whom we have entered into collaboration and license agreements. We classify all of our equity investments in
common stock of publicly-held companies as long term investments on our consolidated balance sheets. our equity investments
are accounted for at fair value using readily determinable pricing available on a securities exchange on our consolidated balance
sheets. all changes in fair value are reported in the consolidated statements of operations as an unrealized gain (loss) on long term
investments.

in assessing whether we exercise significant influence over any of the companies in which we hold equity investments,
we  consider  the  nature  and  magnitude  of  our  investment,  any  voting  and  protective  rights  we  hold,  any  participation  in  the
governance of the other company, and other relevant factors such as the presence of a collaboration or other business relationship.
Currently, none of our equity investments in publicly-held companies are considered

table of Contents

relationships in which we are able to assert control.

Property  and  Equipment,  net.   property  and  equipment,  net  is  stated  at  cost,  less  accumulated  depreciation  and
amortization.  Depreciation  is  recorded  using  the  straight-line  method  over  the  estimated  useful  lives  of  the  respective  assets.
leasehold improvements are amortized over the shorter of the estimated useful life of the assets or lease term.

Lease Accounting.  accounting Standard Codification (“aSC”) 842, leases, was adopted for the fiscal year beginning
on January 1, 2019 using the modified retrospective method. all leases with a lease term greater than 12 months, regardless of
lease type classification, are recorded as an obligation on the balance sheet with a corresponding right-of-use asset. Both finance
and  operating  leases  are  reflected  as  liabilities  on  the  commencement  date  of  the  lease  based  on  the  present  value  of  the  lease
payments to be made over the lease term. Current operating lease liabilities are reflected in accrued and other current liabilities
and noncurrent operating lease liabilities are reflected in other liabilities on the consolidated balance sheet. right-of-use assets are
valued at the initial measurement of the lease liability, plus any initial direct costs or rent prepayments, minus lease incentives and
any deferred lease payments. operating lease right-of-use assets are recorded in property and equipment, net on the consolidated
balance  sheet  and  lease  cost  is  recognized  on  a  straight-line  basis.  For  finance  leases,  expense  is  recognized  as  separate
amortization and interest expense, with higher interest expense in the earlier periods of a lease. leases with an initial term of 12
months or less are not recorded on the balance sheet and we recognize lease expense for these leases on a straight-line basis over
the term of the lease. in determining whether a contract contains a lease, asset and service agreements are assessed at onset and
upon modification for criteria of specifically identified assets, control and economic benefit.

Other  Intangible  Assets,  net. other  intangible  assets,  net  consist  of  licensed  intellectual  property  rights  acquired  in
business  combinations,  which  are  reported  at  acquisition  date  fair  value,  less  accumulated  amortization.  intangible  assets  with
finite lives are amortized over their estimated useful lives using the straight-line method.

Impairment  of  Long-Lived  Assets.   long-lived  assets  with  finite  lives  are  tested  for  impairment  whenever  events  or
changes  in  circumstances  indicate  that  the  carrying  value  of  an  asset  may  not  be  recoverable.    if  indicators  of  impairment  are
present, the asset is tested for recoverability by comparing the carrying value of the asset to the related estimated undiscounted
future cash flows expected to be derived from the asset.  if the expected cash flows are less than the carrying value of the asset,
then  the  asset  is  considered  to  be  impaired  and  its  carrying  value  is  written  down to  fair  value,  based  on  the  related  estimated
discounted future cash flows.

Goodwill.   Goodwill  is  calculated  as  the  difference  between  the  acquisition  date  fair  value  of  the  consideration
transferred  and  the  values  assigned  to  the  assets  acquired  and  liabilities  assumed.    Goodwill  is  not  amortized  but  is  tested  for
impairment at the reporting unit level at least annually as of october 1 or when a triggering event occurs that could indicate a
potential  impairment  by  assessing  qualitative  factors  or  performing  a  quantitative  analysis  in  determining  whether  it  is  more-
likely-than-not  that the fair value of net assets are below their carrying amounts.  a reporting unit is the same as, or one level
below, an operating segment. our operations are currently comprised of a single, entity wide reporting unit. We completed our
most recent annual impairment assessment as of october 1, 2020 and determined that the carrying value of our goodwill was not
impaired.

Income Taxes.   We  account  for  income  taxes  using  the  asset  and  liability  approach  which  requires  the  recognition  of
deferred tax assets and liabilities for the expected future tax consequences of temporary differences between the carrying amount
of assets and liabilities for financial reporting purposes and amounts reportable for income tax purposes. Deferred tax assets are
reduced by a valuation allowance when, in the opinion of management, it is more-likely-than-not that some portion or all of the
deferred tax assets will not be realized.  the primary factors used to assess the likelihood of realization are our recent history of
cumulative earnings or losses, expected reversals of taxable temporary timing differences, forecasts of future taxable income and
available tax planning strategies that could be implemented to realize the deferred tax assets.  upon evaluating and weighting both
positive and negative evidence, we concluded that we should continue to maintain the valuation allowance on the majority of our
deferred tax assets as of December 31, 2020.  

We recognize the tax benefit from an uncertain tax position only if it is more-likely-than-not that the position will be
sustained upon examination by the taxing authorities, including resolutions of any related appeals or litigation processes, based on
the technical merits of the position. the tax benefit that is recorded for these positions is measured at the largest

85

table of Contents

amount  of  benefit  that  is  greater  than  50  percent  likely  of  being  realized  upon  ultimate  settlement.  We  adjust  the  level  of  the
liability to reflect any subsequent changes in the relevant facts surrounding the uncertain positions. any interest and penalties on
uncertain tax positions are included within the tax provision.

the Coronavirus aid, relief, and Economic Security (CarES) act was signed into law in march 2020 to provide an
estimated  $2.2  trillion  designed  to  stimulate  the  u.S.  economy  during  the  CoviD-19  pandemic.    the  act  includes  tax  relief,
government loans, grants and investments for entities in affected industries, which has related accounting and financial reporting
impacts.    Disclosure  for  certain  income  tax  accounting  measures  are  required  in  the  period  of  enactment  and  disclosure  for
government loans, investments, grants, and revenue recognition are required in future periods as federal agencies establish rules
and procedures to implement the CarES act. During the year ended December 31, 2020, we have delayed the payment of certain
employer payroll tax amounts to future periods as allowed under the act. however, we do not expect the CarES act to have a
material impact on our overall financial results, our income tax provision or our liquidity. We have further described the expected
impact and risks of CoviD-19 on our business in item 1. Business and in item 1a. risk Factors.

Net Income (Loss) Per Share.  our basic and diluted net income (loss) per share is calculated by dividing the net income
(loss) by the weighted average number of shares of common stock outstanding during all periods presented. options to purchase
stock, restricted stock units, performance stock units and shares issuable upon the conversion of convertible debt are included in
diluted earnings per share calculations, unless the effects are anti-dilutive.

Accumulated  Other  Comprehensive  Income  (Loss).   accumulated  other  comprehensive  income  (loss)  consists  of
unrealized gains or losses on marketable securities that are classified as available-for-sale, foreign currency translation gains or
losses and defined benefit pension obligations.

Revenue  Recognition.   revenue-generating  contracts  are  assessed  under  aSC  606,  revenue  from  contracts  with
customers, to identify distinct performance obligations, determine the transaction price of the contract and allocate the transaction
price  to  each  of  the  distinct  performance  obligations.  revenue  is  recognized  when  we  have  satisfied  a  performance  obligation
through  transferring  control  of  the  promised  good  or  service  to  a  customer.  Control,  in  this  instance,  may  mean  the  ability  to
prevent other entities from directing the use of, and receiving benefit from, a good or service. We apply the following five-step
model in order to determine this amount: (i) identification of the promised goods or services in the contract; (ii) determination of
whether  the  promised  goods  or  services  are  performance  obligations,  including  whether  they  are  distinct  in  the  context  of  the
contract;  (iii)  measurement  of  the  transaction  price,  including  the  constraint  on  variable  consideration;  (iv)  allocation  of  the
transaction  price  to  the  performance  obligations;  and  (v)  recognition  of  revenue  when  (or  as)  the  Company  satisfies  each
performance obligation, which for the Company is generally at a point in time. We also assess collectability based primarily on
the customer’s payment history and on the creditworthiness of the customer.

Product Revenues

our  product  revenues  consist  of  u.S.  sales  of  JaKaFi  and  pEmaZYrE  and  European  sales  of  iCluSiG.    product
revenues are recognized once we satisfy the performance obligation at a point in time under the revenue recognition criteria as
described  above.  We  sell  JaKaFi  and  pEmaZYrE  to  our  customers  in  the  u.S.,  which  include  specialty  pharmacies  and
wholesalers.  We  sell  iCluSiG  to  our  customers  in  the  European  union  and  certain  other  jurisdictions,  which  include  retail
pharmacies, hospital pharmacies and distributors.

We  recognize  revenues  for  product  received  by  our  customers  net  of  allowances  for  customer  credits,  including
estimated rebates, chargebacks, discounts, returns, distribution service fees, patient assistance programs, and government rebates,
such as medicare part D coverage gap reimbursements in the u.S. product shipping and handling costs are included in cost of
product revenues.

Customer Credits:   our  customers  are  offered  various  forms  of  consideration,  including  allowances,  service  fees  and
prompt  payment  discounts.  We  expect  our  customers  will  earn  prompt  payment  discounts  and,  therefore,  we  deduct  the  full
amount  of  these  discounts  from  total  product  sales  when  revenues  are  recognized.  Service  fees  are  also  deducted  from  total
product sales as they are earned.

86

table of Contents

Rebates and Discounts:  allowances for rebates include mandated discounts under the medicaid Drug rebate program
in the u.S. and mandated discounts in Europe in markets where government-sponsored healthcare systems are the primary payers
for healthcare. rebates are amounts owed after the final dispensing of the product to a benefit plan participant and are based upon
contractual agreements or legal requirements with public sector benefit providers. the accrual for rebates is based on statutory
discount rates and expected utilization as well as historical data we have accumulated since product launches. our estimates for
expected utilization of rebates are based on data received from our customers. rebates are generally invoiced and paid in arrears
so that the accrual balance consists of an estimate of the amount expected to be incurred for the current quarter’s activity, plus an
accrual balance for known prior quarters’ unpaid rebates. if actual future rebates vary from estimates, we may need to adjust prior
period accruals, which would affect revenue in the period of adjustment.

Chargebacks:   Chargebacks  are  discounts  that  occur  when  certain  contracted  customers,  which  currently  consist
primarily  of  group  purchasing  organizations,  public  health  Service  institutions,  non-profit  clinics,  and  Federal  government
entities  purchasing  via  the  Federal  Supply  Schedule,  purchase  directly  from  our  wholesalers.  Contracted  customers  generally
purchase the product at a discounted price. the wholesalers, in turn, charges back to us the difference between the price initially
paid by the wholesalers and the discounted price paid by the contracted customers. in addition to actual chargebacks received we
maintain  an  accrual  for  chargebacks  based  on  the  estimated  contractual  discounts  on  the  inventory  levels  on  hand  in  our
distribution channel. if actual future chargebacks vary from these estimates, we may need to adjust prior period accruals, which
would affect revenue in the period of adjustment.

Medicare Part D Coverage Gap:  medicare part D prescription drug benefit mandates manufacturers to fund 70% of the
medicare part D insurance coverage gap for prescription drugs sold to eligible patients. our estimates for the expected medicare
part D coverage gap are based on historical invoices received and in part from data received from our customers. Funding of the
coverage gap is generally invoiced and paid in arrears so that the accrual balance consists of an estimate of the amount expected
to be incurred for the current quarter’s activity, plus an accrual balance for known prior quarters. if actual future funding varies
from  estimates,  we  may  need  to  adjust  prior  period  accruals,  which  would  affect  revenue  in  the  period  of  adjustment.
additionally, beginning in January 2020, the amount of spending required by eligible patients in the medicare part D insurance
coverage gap increased 30% due to the expiration of a provision in the patient protection and affordable Care act, which now
results in a change in the true out of pocket (troop) calculation methodology. the methodological change has resulted in an
increase  in  required  spending  by  patients  and,  in  turn,  an  increase  in  manufacturers’  contributions  on  behalf  of  patients  in  the
medicare part D insurance coverage gap.

Co-payment Assistance:  patients who have commercial insurance and meet certain eligibility requirements may receive
co-payment  assistance.  We  accrue  a  liability  for  co-payment  assistance  based  on  actual  program  participation  and  estimates  of
program redemption using data provided by third-party administrators.

Product Royalty Revenues

royalty  revenues  on  commercial  sales  for  ruxolitinib  (marketed  as  JaKavi®  outside  the  united  States)  by  novartis
pharmaceutical international ltd. (“novartis”) are based on net sales of licensed products in licensed territories as provided by
novartis. royalty revenues on commercial sales for baricitinib (marketed as olumiant) by Eli lilly and Company (“lilly”)
are based on net sales of licensed products in licensed territories as provided by lilly. royalty revenues on commercial sales for
capmatinib  (marketed  as  taBrECta®)  by  novartis  are  based  on  net  sales  of  licensed  products  in  the  licensed  territories  as
provided by novartis. We recognize royalty revenues in the period the sales occur.

Milestone and Contract Revenues

For  each  collaborative  research,  development  and/or  commercialization  agreement  that  results  in  revenue  under  the
guidance  of  aSC  606,  revenue  from  Contracts  with  Customers,  we  identify  all  material  performance  obligations,  which  may
include the license to intellectual property and know-how, research and development activities and/or other activities. in order to
determine the transaction price, in addition to any upfront payment, we estimate the amount of variable consideration, including
milestone payments, at the outset of the contract utilizing the most likely amount method. the most likely amount method is used
since the milestone  payments have a binary outcome (i.e., we receive  all or none of the milestone  payment).  We constrain  the
estimate of variable consideration such that it is probable that a significant

87

table of Contents

reversal  of  previously  recognized  revenue  will  not  occur.  When  determining  if  variable  consideration  should  be  constrained,
management  considers  whether  there  are  factors  outside  the  Company’s  control  that  could  result  in  a  significant  reversal  of
revenue.  in  making  these  assessments,  management  considers  the  likelihood  and  magnitude  of  a  potential  reversal  of  revenue.
these estimates are re-assessed each reporting period as required. once the estimated transaction price is established, amounts are
allocated  to the performance  obligations  that have been identified.  the transaction  price is generally allocated  to each separate
performance obligation on a relative standalone selling price basis.

out-licensing arrangements contain the right to use functional intellectual property, which is the underlying performance
obligation of these collaborative arrangements. if the license of our intellectual property is determined to be distinct from other
performance obligations in the arrangement, the functional intellectual property that is transferred to the collaborative partner at
the onset of the arrangement is concluded to have significant standalone functionality and value at the point in time at which the
intellectual  property  is  made  available  to  the  collaborative  partner.  For  licenses  that  are  not  distinct  from  other  obligations
identified  in  the  arrangement,  we  utilize  judgment  to  assess  the  nature  of  the  combined  performance  obligation  to  determine
whether the combined performance obligation is satisfied over time or at a point in time. if the combined performance obligation
is  satisfied  over  time,  we  apply  an  appropriate  method  of  measuring  progress  for  purposes  of  recognizing  revenue  from
nonrefundable,  upfront  license  fees.  We  evaluate  the  measure  of  progress  each  reporting  period  and,  if  necessary,  adjust  the
measure  of  performance  and  related  revenue  recognition.  For  each  of  the  three  years  ended  December  31,  2020,  we  had  no
revenues from intellectual licenses recognized over time.

For milestone revenues related to sales-based achievements, we recognize the milestone revenues in the corresponding
period  of  the  product  sale,  in  accordance  with  the  guidance  of  aSC  606-10-55-65  for  contracts  that  include  a  license  to
intellectual property and the license is the predominant item to which the product sale relates.

Subsequent  to  the  transfer  of  the  intellectual  property,  we  may  earn  milestones  through  achievement  of  pre-specified
developmental  or  regulatory  events  and,  as  such,  milestones  are  accounted  for  as  variable  consideration.  We  include
developmental or regulatory milestones in the transaction price only to the extent that it is probable that a significant reversal in
the amount of cumulative revenue recognized will not occur when the uncertainty associated with the milestone is subsequently
resolved. under the agreements currently in place, we do not consider these events to be within our control, but rather dependent
upon the development activities of our collaborative partners and the decisions made by regulatory agencies. accordingly, these
milestones are not included in the transaction price until the counterparty, or third-party in the event of a regulatory submission,
confirms  the  satisfaction  or  completion  of  the  milestone  triggering  event.  Given  the  high  level  of  uncertainty  of  achievement,
variable consideration associated with milestones are fully constrained until confirmation of the satisfaction or completion of the
milestone by the third-party.

Generally,  the  milestone  events  contained  in  our  collaboration  agreements  coincide  with  the  progression  of  our  drugs
from  development,  to  regulatory  approval  and  then  to  commercialization.  the  value  of  these  milestones  is  dictated  within  the
contract and is fixed upon achievement and reflects the amount of consideration which we expect to be entitled to in exchange for
the satisfaction of that milestone. the process of successfully discovering a new development candidate, having it approved and
successfully  commercialized  is  highly  uncertain.  as  such,  the  milestone  payments  we  may  earn  from  our  partners  involve  a
significant degree of risk to achieve and therefore, subsequent milestone payments due to incyte are recognized as revenue at the
point in time when such milestones are achieved.

our collaboration agreements may also include an option for the collaborative partner to elect to participate in research
and  development  activities,  such  as  shared  participation  in  additional  clinical  trials  using  the  compound.  the  presence  of
additional options for future participatory activities are assessed to determine if they represent material rights offered by us to the
collaborative partner. We also determine whether the reimbursement of research and development expenses should be accounted
for as collaborative revenues or an offset to research and development expenses in accordance with the provisions of gross or net
revenue presentation and recognize the corresponding revenues or records the corresponding offset to research and development
expenses as incurred.

our collaborative agreements may also include provisions for additional future collaborative efforts, such as options for
shared commercialization staffing or licensing of additional molecules, involvement in joint committees, or options for inclusion
in negotiations of future supply rights, which at the time of each collaborative agreement’s inception, are assessed to determine if
these meet the definition of a performance obligation under aSC 606.

Cost of Product Revenues

Cost of product revenues includes all JaKaFi, iCluSiG and pEmaZYrE related  product costs. in addition, cost of
product revenues include low single-digit royalties under our collaboration and license agreement to novartis on all future sales
of  JaKaFi  in  the  united  States  and  the  amortization  of  our  licensed  intellectual  property  for  iCluSiG  using  the  straight-line
method over the estimated useful life of 12.5 years from the date of acquisition on June 1, 2016 of all of the outstanding shares of
ariaD  pharmaceuticals  (luxembourg)  S.à.r.l.  (since  renamed  incyte  Biosciences  luxembourg  S.à.r.l.)  from  ariaD
pharmaceuticals,  inc.  (“ariaD”).  Cost  of  product  revenues  also  includes  employee  personnel  costs,  including  stock
compensation, for those employees dedicated to the production of our commercial products.    

Research  and  Development  Costs.   our  policy  is  to  expense  research  and  development  costs  as  incurred,  including
amounts  funded  by  research  and  development  collaborations.  research  and  development  expenses  are  comprised  of  costs  we
incur  in  performing  research  and  development  activities,  including  salary  and  benefits;  stock-based  compensation  expense;
outsourced  services  and  other  direct  expenses,  including  clinical  trial  and  pharmaceutical  development  costs;  collaboration
payments; expenses associated with drug supplies that are not being capitalized; and infrastructure costs, including facilities costs
and  depreciation  expense.  if  a  collaboration  is  a  cost-sharing  arrangement  in  which  both  we  and  our  collaborator  perform
development work and share costs, we also recognize, as research and development expense in the period when our collaborator
incurs development expenses, our portion of the co-development expenses that we are obligated to reimburse.

We  often  contract  with  clinical  research  organizations  (“Cros”)  to  facilitate,  coordinate  and  perform  agreed  upon
research  and  development  of  a  new  drug.  to  ensure  that  research  and  development  costs  are  expensed  as  incurred,  we  record
monthly  accruals  for  clinical  trials  and  preclinical  testing  costs  based  on  the  work  performed  under  the  contract.  these  Cro
contracts typically call for the payment of fees for services at the initiation of the contract and/or upon the achievement of certain
clinical trial milestones. in the event that we prepay Cro fees, we record the prepayment as a prepaid asset and amortize the asset
into research and development expense over the period of time the contracted research and development services are performed.
most professional fees, including project and clinical management, data management, monitoring, and medical writing fees are
incurred  throughout  the  contract  period.  these  professional  fees  are  expensed  based  on  their  percentage  of  completion  at  a
particular  date.  our  Cro  contracts  generally  include  pass  through  fees.  pass  through  fees  include,  but  are  not  limited  to,
regulatory  expenses,  investigator  fees,  travel  costs,  and  other  miscellaneous  costs,  including  shipping  and  printing  fees.  We
expense the costs of pass through fees under our Cro contracts as they are incurred, based on the best information available to us
at the time. the estimates of the pass through fees incurred are based on the amount of work completed for the clinical trial and
are monitored through correspondence with the Cros, internal reviews and a review of contractual terms. the factors utilized to
derive the estimates include the number of patients enrolled, duration of the clinical trial, estimated patient attrition, screening rate
and length of the dosing regimen. Cro fees incurred to set up the clinical trial are expensed during the setup period. under our
clinical trial collaboration agreements we may be reimbursed for certain development costs incurred. Such costs are recorded as a
reduction of research and development expense in the period in which the related expense is incurred.

Stock Compensation.  Share-based payment transactions with employees, which include stock options, restricted stock
units (“rSus”) and performance shares (“pSus”), are recognized as compensation expense over the requisite service period based
on their estimated fair values as well as expected forfeiture rates.  the stock compensation process requires significant judgment
and the use of estimates, particularly surrounding Black-Scholes assumptions such as stock price volatility over the option term
and  expected  option  lives,  as  well  as  expected  forfeiture  rates  and  the  probability  of  pSus  vesting.    the  fair  value  of  stock
options, which are subject to graded vesting, are recognized as compensation expense over the requisite service period using the
accelerated attribution method.  the fair value of rSus that are subject to cliff vesting are recognized as compensation expense
over the requisite service period using the straight-line attribution method, and the fair value of rSus that are subject to graded
vesting are recognized as compensation expense over the requisite service period using the accelerated attribution method.  the
fair  value  of  pSus  are  recognized  as  compensation  expense  beginning  at  the  time  in  which  the  performance  conditions  are
deemed  probable  of  achievement,  which  we  assess  as  of  the  end  of  each  reporting  period.  once  a  performance  condition  is
considered probable, we record compensation expense based on the portion of the service period elapsed to date with respect to
that award, with a cumulative catch-up, net of estimated forfeitures, and recognize any remaining compensation expense, if any,
over the remaining requisite service period using

89

table of Contents

the straight-line attribution method for pSus that are subject to cliff vesting and using the accelerated attribution method for pSus
that are subject to graded vesting.

Advertising  Expenses.  advertising  expenses,  comprised  primarily  of  television,  radio,  print  media  and  internet
advertising,  are  expensed  as  incurred  and  are  included  in  selling,  general,  and  administrative  expenses.  For  the  years  ended
December 31, 2020, 2019, and 2018, advertising expenses were approximately $28.9 million, $15.3 million, and $10.6 million,
respectively.

Long Term Incentive Plans. We have long term incentive plans which provide eligible employees with the opportunity to
receive performance and service-based incentive compensation, which may be comprised of cash, stock options, restricted stock
units and/or performance shares. the payment of cash and the grant or vesting of equity may be contingent upon the achievement
of pre-determined regulatory, sales and internal performance milestones.

Acquisition-Related  Contingent  Consideration. acquisition-related  contingent  consideration  consists  of  our  future
royalty  obligations  on  future  net  sales  of  iCluSiG  to  takeda  pharmaceutical  Company  limited,  which  acquired  ariaD
(“takeda”).  acquisition-related  contingent  consideration  was recorded  on the acquisition  date of June 1, 2016 at the estimated
fair value of the obligation, in accordance with the acquisition method of accounting.  the fair value measurement is based on
significant  inputs  that  are  unobservable  in  the  market  and  thus  represents  a  level  3  measurement.  the  fair  value  of  the
acquisition-related  contingent  consideration  is  remeasured  each  reporting  period,  with  changes  in  fair  value  recorded  in  the
consolidated statements of operations.  

Collaboration  loss  sharing.   under  collaboration  and  license  agreements  with  shared  commercialization  efforts,  we
record our share of the losses from the co-commercialization efforts in collaboration loss sharing on the consolidated statement of
operations. For the year ended December 31, 2020, collaboration loss sharing represents our 50% share of the united States loss
for commercialization of monJuvi (tafasitamab) under our agreement with morphoSys, which is described in note 6 below.

Recent Accounting Pronouncements

in June 2016, the Financial accounting Standards Board (“FaSB”) issued aSu no. 2016-13, “Financial instruments –
Credit  losses  (topic  326):  measurement  of  Credit  losses  on  Financial  instruments.”  this  guidance  applies  to  all  entities  and
impacts how entities account for credit losses for financial assets measured at amortized cost and available for sale debt securities.
aSu 2016-13 requires financial assets measured at amortized cost to be presented at the net amount expected to be collected. the
measurement of expected credit losses is based on relevant information about past events, including historical experience, current
conditions,  and  reasonable  and  supportable  forecasts  that  affect  the  collectability  of  the  reported  amounts.  an  entity  must  use
judgment  in  determining  the  relevant  information  and  estimation  methods  that  are  appropriate  in  its  circumstances.    For  trade
receivables, loans and held-to-maturity debt securities, entities are required to estimate expected credit losses over the lifetime of
the asset.  For available-for-sale debt securities, entities will be required to recognize an allowance for credit losses rather than an
other-than-temporary impairment that reduces the cost basis of the investment. Further, an entity recognizes any improvements in
estimated credit losses on its available-for-sale debt securities immediately in earnings.

upon adoption, we  assessed each financial  asset  measured at  amortized  cost and  each  available-for-sale debt  security
held  for  the  impact  of  the  guidance  as  of  January  1,  2020  and  noted  an  insignificant  impact  due  to  the  minimal  credit  risk
associated with our financial assets subject to aSC 326. as such, it was concluded that a reserve for credit losses was de minimis
on the adoption date. Financial assets will continue to be assessed on a quarterly basis in future periods.

in august 2018, the FaSB issued aSu no. 2018-13, “Fair value measurement (topic 820): Disclosure Framework –
Changes to the Disclosure requirements for Fair value measurement,” which eliminates the required disclosure of the amount of
and  reason  for  transfers  between  level  1  and  level  2  of  the  fair  value  hierarchy.  the  guidance  also  eliminates  the  required
disclosure of the entity’s valuation process for level 3 fair value measurements, however public entities are required to disclose
the  range  and  weighted  average  used  to  develop  significant  unobservable  inputs  for  level  3  fair  value  measurements.  this
guidance  is  effective  for  fiscal  years  beginning  after  December  15,  2019.  We  adopted  this  guidance  for  the  period  beginning
January 1, 2020 and enhanced our disclosures in note 3 to the consolidated

90

table of Contents

financial statements to comply with the standard.  

in august 2018, the FaSB issued aSu no. 2018-14, “Compensation – retirement Benefits – Defined Benefit plans –
General,” an update to Subtopic aSC 715-20. the guidance amended year-end disclosure requirements related to defined benefit
pension plans, and does not affect interim disclosures. the guidance is effective for fiscal years ending after December 15, 2020
and is permitted for early adoption. the standard is to be applied on a retrospective basis. incyte sponsors defined benefit plans
for  employees  located  in  Europe  and  have  adopted  this  guidance  for  the  period  ending  December  31,  2020  as  reflected  in  our
disclosures in note 15.

in august 2018, the FaSB issued aSu no. 2018-15, “intangibles – Goodwill and other – internal-use Software,” an
update  to  Subtopic  aSC  350-40.  the  guidance  directs  accounting  for  service  contracts  for  cloud  computing  arrangements  to
follow guidance within aSC 350-40 to determine capitalization of implementation costs. the guidance is effective for fiscal years
beginning after December 15, 2019 and may be applied on either a retrospective or prospective basis. We adopted this guidance
for the period  beginning  January 1, 2020 on a prospective  basis. new contracts  for development  of internal-use  software  were
assessed  and  no  qualifying  contracts  were  identified  during  the  period.  We  will  continue  to  assess  contracts  and  will  disclose
material, qualifying contracts if identified in future periods.

in  november  2018,  the  FaSB  issued  aSu  no.  2018-18,  “Collaborative  arrangements  (topic  808):  Clarifying  the
interaction  Between  topic  808  and  topic  606.”  the  guidance  clarifies  the  interactions  between  topic  808  and  topic  606,
including clarifications on revenue recognition, unit of account, and reporting disclosure requirements. the guidance is effective
for  fiscal  years  beginning  after  December  15,  2019.  We  adopted  this  guidance  for  the  period  beginning  January  1,  2020
retrospectively  to the date of our initial application of aSC 606, and noted that in assessment of our collaborative  agreements,
there was no material financial statement impact. our collaborative arrangements and their associated accounting conclusions are
described in detail within note 6 to the consolidated financial statements.

in December  2019, the FaSB issued aSu no. 2019-12, “income  taxes (topic 740): Simplifying  the accounting for
income  taxes.”  this  guidance  applies  to  all  entities  and  aims  to  reduce  the  complexity  of  tax  accounting  standards  while
enhancing  reporting  disclosures.  this  guidance  is  effective  for  fiscal  years  beginning  after  December  15,  2020  and  interim
periods  therein.  Early  adoption  is  permitted  for  any  annual  periods  for  which  financial  statements  have  not  been  issued  and
interim periods therein. We are currently analyzing the impact of aSu no. 2019-12 on the consolidated financial statements.

our  debt  securities  generally  have  contractual  maturity  dates  of  between  12 to  18  months.  Debt  security  assets  were
assessed for risk of expected credit losses per our accounting policy as described in note 1. as of December 31, 2020 and 2019,
the available-for-sale debt securities were held in u.S. government debt securities and treasury assets and were assessed on an
individual security basis to have a de minimis risk of credit loss.

Fair Value Measurements

FaSB accounting guidance defines fair value as the price that would be received  to sell an asset or paid to transfer  a
liability (“the exit price”) in an orderly transaction between market participants at the measurement date. the standard outlines a
valuation  framework  and  creates  a  fair  value  hierarchy  in  order  to  increase  the  consistency  and  comparability  of  fair  value
measurements  and  the  related  disclosures.  in  determining  fair  value  we  use  quoted  prices  and  observable  inputs.  observable
inputs are inputs that market participants would use in pricing the asset or liability based on market data obtained from sources
independent of us. the fair value hierarchy is broken down into three levels based on the source of inputs as follows:

level 1—valuations based on unadjusted quoted prices in active markets for identical assets or liabilities.

level 2—valuations based on observable inputs and quoted prices in active markets for similar assets and liabilities.

level  3—valuations  based  on  inputs  that  are  unobservable  and  models  that  are  significant  to  the  overall  fair  value
measurement.

Recurring Fair Value Measurements

our marketable securities consist of investments in u.S. government debt securities that are classified as available-for-

sale.

at  December  31,  2020  and  2019,  our  level  2  u.S.  government  debt  securities  were  valued  using  readily  available
pricing  sources  which  utilize  market  observable  inputs,  including  the  current  interest  rate  and  other  characteristics  for  similar
types of investments.  our long term investments classified as level 1 were valued using their respective closing stock prices on
the nasdaq Stock market.  We did not experience any transfers of financial instruments between the fair value hierarchy levels
during the years ended December 31, 2020 and 2019.

the fair value of the contingent consideration was determined on the date of acquisition, June 1, 2016, using an income
approach based on estimated iCluSiG revenues in the European union and other countries for the approved third line treatment
over 18 years, and discounted to present value at a rate of 10%. the fair value of the contingent consideration is remeasured each
reporting period, with changes in fair value recorded in the consolidated statements of operations. the valuation inputs utilized to
estimate the fair value of the contingent consideration as of December 31, 2020 included a weighted average cost of capital of
10% and updated projections of future iCluSiG revenues in the European union and other countries for the approved third line
treatment. the change in fair value of the contingent consideration during the years ended December 31, 2020 and 2019 was due
primarily to the passage of time as there were no other significant changes in the key assumptions.

We  make  payments  to  takeda  quarterly  based  on  the  royalties  or  any  additional  milestone  payments  earned  in  the
previous quarter. as of December 31, 2020 and 2019, contingent consideration earned but not yet paid was $9.6 million and $23.0
million, respectively, and was included in accrued and other current liabilities.

Non-Recurring Fair Value Measurements

During the years ended December 31, 2020 and 2019, there were no measurements required for any assets or liabilities

at fair value on a non-recurring basis.

Note 4. Concentrations of Credit Risk and Current Expected Credit Losses

in november 2009, we entered into a collaboration and license agreement with novartis. in December 2009, we entered
into  a  license,  development  and  commercialization  agreement  with  lilly.  in  December  2018,  we  entered  into  a  research
collaboration and licensing agreement with innovent Biologics, inc. (“innovent”). in July 2019, we entered into a collaboration
and license agreement with Zai lab (Shanghai) Co., ltd., a subsidiary of Zai lab limited (collectively, “Zai lab”). the above
collaboration partners comprised, in aggregate, 42% and 30% of the accounts receivable balance as of December 31, 2020 and
2019, respectively. For further information relating to these collaboration and license agreements, refer to note 6.

in  november  2011,  we  began  commercialization  and  distribution  of  JaKaFi  and  in  april  2020,  we  began
commercialization and distribution of pEmaZYrE to a number of customers. our product revenues are concentrated in a number
of these customers. the concentration of credit risk related to our JaKaFi and pEmaZYrE product revenues is as follows:

respectively. the concentration of credit risk relating to iCluSiG product revenues or accounts receivable is not significant.

We  assessed  our  collaborative  and  customer  receivable  assets  as  of  December  31,  2020  according  to  our  accounting
policy  for  applying  reserves  for  expected  credit  losses,  noting  minimal  history  of  uncollectible  receivables  and  the  continued
perceived  creditworthiness  of  our  third  party  sales  relationships,  upon  which  the  expected  credit  losses  were  considered  de

inventories, stated at the lower of cost and net realizable value, consist of raw materials, work-in-process and finished
goods. at December 31, 2020, $16.4 million of inventory was classified as current on the consolidated balance sheet as we expect
this  inventory  to  be  consumed  for  commercial  use  within  the  next  twelve  months.  at  December  31,  2020,  $19.5  million  of
inventory was classified as non-current on the consolidated balance sheet as we did not expect this inventory to be consumed for
commercial use within the next twelve months. We obtain some inventory components from a limited number of suppliers due to
technology, availability, price, quality or other considerations. the loss of a supplier, the deterioration of our relationship with a
supplier,  or  any  unilateral  violation  of  the  contractual  terms  under  which  we  are  supplied  components  by  a  supplier  could
adversely affect our total revenues and gross margins.

Note 6. License Agreements

Novartis

in  november  2009,  we  entered  into  a  Collaboration  and  license  agreement  with  novartis.  under  the  terms  of  the
agreement,  novartis  received  exclusive  development  and  commercialization  rights  outside  of  the  united  States  to  our  JaK
inhibitor  ruxolitinib  and  certain  back-up  compounds  for  hematologic  and  oncology  indications,  including  all  hematological
malignancies, solid tumors and myeloproliferative diseases. We retained exclusive development and commercialization rights to
JaKaFi  (ruxolitinib)  in  the  united  States  and  in  certain  other  indications.  novartis  also  received  worldwide  exclusive
development  and  commercialization  rights  to  our  mEt  inhibitor  compound  capmatinib  and  certain  back-up  compounds  in  all
indications.

95

 
 
 
table of Contents

under this agreement, we received an upfront payment and immediate milestone payment totaling $210.0 million and
were initially eligible to receive up to $1.2 billion in milestone payments across multiple indications upon the achievement of pre-
specified  events,  including  up  to  $174.0  million  for  the  achievement  of  development  milestones,  up  to  $495.0  million  for  the
achievement  of  regulatory  milestones  and  up  to  $500.0  million  for  the  achievement  of  sales  milestones.  in  april  2016,  we
amended this agreement to provide that novartis has exclusive research, development and commercialization rights outside of the
united States to ruxolitinib (excluding topical formulations) in the graft-versus-host-disease (“GvhD”) field. We became eligible
to receive up to $75.0 million of additional potential development and regulatory milestones relating to GvhD.

Exclusive  of  the  upfront  payment  of  $150.0  million  received  in  2009  and  the  immediate  milestone  of  $60.0  million
earned  in  2010,  we  have  recognized  and  received,  in  the  aggregate,  $157.0  million  for  the  achievement  of  development
milestones,  $280.0  million  for  the  achievement  of  regulatory  milestones  and  $200.0  million  for  the  achievement  of  sales
milestones through December 31, 2020.

We recognize development and regulatory milestones upon confirmation of achievement of the event, as development
and regulatory approvals are events not controllable by us but rather development activities of novartis and decisions made by
regulatory agencies. We recognize sales milestones in the corresponding period of the product sale upon confirmation of net sales
milestone threshold achievement by novartis.

in 2020, we recognized a $25.0 million development milestone and a $45.0 million regulatory milestone for the FDa
approval of capmatinib as taBrECta for the treatment of adult patients with metastatic non-small cell lung cancer (nSClC)
whose tumors have a mutation  that leads to mEt exon 14 skipping (mEtex14) as detected  by an FDa-approved test, a $20.0
million  regulatory  milestone  for  the  Japanese  ministry  of  health,  labour  and  Welfare  approval  of  taBrECta  for  mEtex14
mutation-positive  advanced  and/or  recurrent  unresectable  non-small  cell  lung  cancer  and  a  $80.0  million  sales  milestone  for
novartis  achieving  annual  net  sales  of  a  JaK  licensed  product  of  $1.2  billion.  in  2018,  we  recognized  a  $60.0  million  sales
milestone for novartis achieving annual net sales of a JaK licensed product of $900.0 million.

We also are eligible to receive tiered, double-digit royalties ranging from the upper-teens to the mid-twenties on future
JaKavi net sales outside of the united States, and tiered, worldwide royalties on future taBrECta net sales that range from
12% to 14%. Since the achievement of the $60.0 million regulatory milestone related to reimbursement of JaKavi in Europe in
September 2014, we are obligated to pay to novartis tiered royalties in the low single-digits on future JaKaFi net sales within
the united States. During the years ended December  31, 2020, 2019 and 2018, such royalties  payable to novartis on net sales
within the united States totaled $89.9 million, $77.6 million and $63.0 million, respectively, and were reflected in cost of product
revenues  on  the  consolidated  statements  of  operations.  at  December  31,  2020  and  2019,  $96.4  million  and  $50.2  million,
respectively, of accrued royalties payable to novartis were included in accrued and other current liabilities on the consolidated
balance  sheets.  Each  company  is  responsible  for  costs  relating  to  the  development  and  commercialization  of  ruxolitinib  in  its
respective territories, with costs of collaborative studies shared equally. novartis is also responsible for all costs relating to the
development and commercialization of capmatinib.

the novartis agreement will continue on a program-by-program basis until novartis has no royalty payment obligations
with respect to such program or, if earlier, the termination of the agreement or any program in accordance with the terms of the
agreement. royalties are payable by novartis on a product-by-product and country-by-country basis until the latest to occur of
(i) the expiration of the last valid claim of the licensed patent rights covering the licensed product in the relevant country, (ii) the
expiration of regulatory exclusivity for the licensed product in such country and (iii) a specified period from first commercial sale
in  such  country  of  the  licensed  product  by  novartis  or  its  affiliates  or  sublicensees.  the  agreement  may  be  terminated  in  its
entirety or on a program-by-program basis by novartis for convenience. the agreement may also be terminated by either party
under certain other circumstances, including material breach.

reimbursable costs incurred after the effective date of the agreement with novartis are recorded net against the related
research and development expenses. research and development expenses for the years ended December 31, 2020, 2019 and 2018
were net of $0.3 million, $1.5 million, and $3.2 million, respectively, of costs reimbursed by novartis. at December 31, 2020 and
2019, $0.2 million and $0.4 million, respectively, of reimbursable costs were included in accounts receivable on the consolidated
balance sheets.

table of Contents

milestone and contract revenue under the novartis agreement was $170.0 million, $0.0 million and $60.0 million for the
years  ended  December  31,  2020,  2019  and  2018,  respectively.  in  addition,  for  the  years  ended  December  31,  2020,  2019  and
2018,  we  recorded  $277.9  million,  $225.9  million  and  $194.7  million,  respectively,  of  product  royalty  revenues  related  to
novartis  net  sales  of  JaKavi  outside  the  united  States.  For  the  year  ended  December  31,  2020  we  recorded  $4.1  million  of
product royalty revenues related to novartis net sales of taBrECta worldwide.

Lilly - Baricitinib

in December 2009, we entered into a license, Development and Commercialization  agreement with lilly. under the
terms  of  the  agreement,  lilly  received  exclusive  worldwide  development  and  commercialization  rights  to  our  JaK  inhibitor
baricitinib,  and  certain  back-up  compounds  for  inflammatory  and  autoimmune  diseases.  We  received  an  upfront  payment  of
$90.0  million,  and  were  initially  eligible  to  receive  up  to  $665.0  million  in  substantive  milestone  payments  across  multiple
indications  upon  the  achievement  of  pre-specified  events,  including  up  to  $150.0  million  for  the  achievement  of  development
milestones, up to $365.0 million for the achievement of regulatory milestones and up to $150.0 million for the achievement of
sales  milestones.  Exclusive  of  the  upfront  payment  of  $90.0  million  received  in  2009,  we  have  recognized  and  received,  in
aggregate, $149.0 million for the achievement of development milestones and $265.0 million for the achievement of regulatory
milestones through December 31, 2020.

We recognize development and regulatory milestones upon confirmation of achievement of the event, as development
and  regulatory  approvals  are  events  not  controllable  by  us  but  rather  development  activities  of  lilly  and  decisions  made  by
regulatory agencies. We recognize sales milestones in the corresponding period of the product sale upon confirmation of net sales
milestone threshold achievement by lilly.

in  January  2016,  lilly  submitted  an  nDa  to  the  FDa  and  a  marketing  authorization  application  (maa)  to  the
European medicines agency for baricitinib as treatment for rheumatoid arthritis. in February 2017, we and lilly announced that
the European Commission approved baricitinib as olumiant for the treatment of moderate-to-severe rheumatoid arthritis in
adult patients who have responded inadequately to, or who are intolerant to, one or more disease-modifying antirheumatic drugs.
in July 2017, Japan's  ministry  of health,  labor and Welfare  granted  marketing  approval  for olumiant for  the  treatment  of
rheumatoid arthritis in patients with inadequate response to standard-of-care therapies.  in June 2018, the FDa approved the 2mg
dose  of  olumiant  for  the  treatment  of  adults  with  moderately-to-severely  active  rheumatoid  arthritis  who  have  had  an
inadequate response to one or more tumor necrosis factor inhibitor therapies. in october 2020, lilly announced that the European
Commission approved baricitinib as olumiant for the treatment of moderate-to-severe atopic dermatitis in adult patients who
are candidates for systemic therapy.  

in  2020,  we  recognized  a  $20.0  million  regulatory  milestone  for  the  European  Commission  approval  of  olumiant
and a $10.0 million regulatory milestone for the mhlW approval of olumiant for the treatment of moderate-to-severe atopic
dermatitis  in  adult  patients  who  are  candidates  for  systemic  therapy.  in  2018,  we  recognized  a  $20.0  million  development
milestone for the first patient treated in the systemic lupus erythematosus phase iii program for baricitinib and a $100.0 million
regulatory  milestone  for  the  FDa  approval  of  the  2mg  dose  of  olumiant  for  the  treatment  of  adults  with  moderately-to-
severely active rheumatoid arthritis.

We retained options to co-develop our JaK1/JaK2 inhibitors with lilly on a compound-by-compound and indication-
by-indication basis. lilly is responsible for all costs relating to the development and commercialization of the compounds unless
we elect to co-develop any compounds or indications. if we elect to co-develop any compounds and/or indications, we would be
responsible  for  funding  30%  of  the  associated  future  global  development  costs  from  the  initiation  of  a  phase  iib  trial  through
regulatory approval, including post-launch studies required by a regulatory authority. We would receive an incremental royalty
rate increase across all tiers resulting in effective royalty rates ranging up to the high twenties on potential future global net sales
for compounds and/or indications that we elect to co-develop.  For indications that we elect not to co-develop, we would receive
tiered,  double-digit  royalty  payments  on  future  global  net  sales  with  rates  ranging  up  to  20%  if  the  product  is  successfully
commercialized.  if we have started co-development funding for any indication, we can at any time opt out and stop future co-
development  cost  sharing.  if  we elect  to  do this  we  would still  be  eligible  for  our  base  royalties  plus  an  incremental  pro-rated
royalty commensurate with our contribution to the total co-development cost for those indications for which we co-funded.  We
previously had retained an option to co-promote products in the united States but, in march 2016, we waived our co-promotion
option as part of an amendment to the agreement.

in July 2010, we elected to co-develop baricitinib with lilly in rheumatoid arthritis and became responsible for funding
30%  of  the  associated  future  global  development  costs  for  this  indication  from  the  initiation  of  the  phase  iib  trial  through
regulatory  approval,  including  post-launch  studies  required  by  a  regulatory  authority.    We  subsequently  elected  to  co-develop
baricitinib  with  lilly  in  psoriatic  arthritis,  atopic  dermatitis,  alopecia  areata,  systemic  lupus  erythematosus  and  axial
spondyloarthritis  and  were  responsible  for  funding  30%  of  future  global  development  costs  for  those  indications  through
regulatory approval, including post-launch studies required by a regulatory authority. in april 2019, we elected to end additional
co-funding of the development of baricitinib effective as of January 1, 2019. We will continue to receive royalties on global net
sales of olumiant, pursuant to the terms in the lilly agreement, as described above.

We  recorded  no  research  and  development  expense  under  the  lilly  agreement  for  co-funding  the  development  of
baricitinib  for  the  years  ended  December  31,  2020  and  2019.  research  and  development  expenses  recorded  under  the  lilly
agreement  representing  30%  of  the  global  development  costs  for  baricitinib  for  the  treatment  of  rheumatoid  arthritis,  psoriatic
arthritis, atopic dermatitis, alopecia areata, systemic lupus erythematosus and axial spondyloarthritis for the year ended December
31, 2018 was $68.6 million.

in  may  2020,  we  amended  our  agreement  with  lilly  to  enable  lilly  to  develop  and  commercialize  baricitinib  for  the
treatment of CoviD-19. as part of the amended agreement, in addition to the royalties described above, we will be entitled to
receive additional royalty payments with rates in the low teens on global net sales of baricitinib for the treatment of CoviD-19
that exceed a specified aggregate global net sales threshold.

the lilly agreement will continue until lilly no longer has any royalty payment obligations or, if earlier, the termination
of the  agreement  in  accordance  with its  terms.  royalties  are  payable  by lilly  on a product-by-product  and country-by-country
basis until the latest to occur of (i) the expiration of the last valid claim of the licensed patent rights covering the licensed product
in the relevant country, (ii) the expiration of regulatory exclusivity for the licensed product in such country and (iii) a specified
period from first commercial sale in such country of the licensed product by lilly or its affiliates or sublicensees. the agreement
may be terminated by lilly for convenience, and may also be terminated under certain other circumstances, including material
breach.

milestone  and  contract  revenue  under  the  lilly  agreement  was  $30.0  million,  $0.0  million  and  $120.0  million,
respectively, for the years ended December 31, 2020, 2019 and 2018. in addition, for the years ended December 31, 2020, 2019
and 2018, we recorded $110.9 million, $80.4 million and $40.1 million, respectively, of product royalty revenues related to lilly
net sales of olumiant outside the united States.  

Lilly – Ruxolitinib

in march 2016, we entered into an amendment to the agreement with lilly that amended the non-compete provision of
the agreement to allow us to engage in the development and commercialization of ruxolitinib in the GvhD field. upon execution
of  the  amendment,  we  paid  lilly  an  upfront  payment  of  $35.0  million  and  lilly  is  eligible  to  receive  up  to  $40.0  million  in
regulatory  milestone  payments  relating  to  ruxolitinib  in  the  GvhD  field.    in  may  2019,  the  approval  of  JaKaFi  in  steroid-
refractory acute GvhD triggered a $20.0 million milestone payment to lilly.

Agenus

in January 2015, we entered into a license, Development and Commercialization agreement with agenus inc. and its
wholly-owned subsidiary, 4-antibody aG (now known as agenus Switzerland inc.), which we collectively refer to as agenus.
under  this  agreement,  the  parties  have  agreed  to  collaborate  on  the  discovery  of  novel  immuno-therapeutics  using  agenus’
antibody discovery platforms. the agreement became effective on February 18, 2015, upon the expiration of the waiting period
under  the  hart-Scott-rodino  antitrust  improvements  act  of  1976.  upon  closing  of  the  agreement,  we  paid  agenus  total
consideration of $60.0 million.

in  February  2017,  we  and  agenus  amended  this  agreement  (the  “amended  agreement”).  under  the  terms  of  the
amended agreement, we received exclusive worldwide development and commercialization rights to four checkpoint modulators
directed against Gitr, ox40, laG-3 and tim-3. in addition to the initial four program targets, we and agenus have the option
to jointly nominate and pursue additional targets within the framework of the collaboration, and in

98

table of Contents

november 2015, three more targets were added. targets may be designated profit-share programs, where all costs and profits are
shared equally by us and agenus, or royalty-bearing programs, where we are responsible for all costs associated with discovery,
preclinical,  clinical  development  and  commercialization  activities.  the  programs  relating  to  Gitr  and  ox40  and  two  of  the
undisclosed  targets  were  profit-share  programs  until  February  2017,  while  the  other  targets  currently  under  collaboration  are
royalty-bearing  programs.  the  amended  agreement  converted  the  programs  relating  to  Gitr  and  ox40  to  royalty-bearing
programs and removed from the collaboration the profit-share programs relating to the two undisclosed targets, with one reverting
to us and one reverting to agenus.  Should any of those removed programs be successfully developed by a party, the other party
will be eligible to receive the same milestone payments as the royalty-bearing programs and royalties at a 15% rate on global net
sales.  there are currently no profit-share programs.  For each royalty-bearing product other than Gitr and ox40, agenus will
be eligible to receive tiered royalties on global net sales ranging from 6% to 12%.  For Gitr and ox40, agenus will be eligible
to receive 15% royalties on global net sales.

in 2017 under the amended agreement, we paid agenus $20.0 million in accelerated milestones relating to the clinical
development of the Gitr and ox40 programs, which was recorded in research and development expense. agenus was initially
eligible  to  receive  up  to  an  additional  $510.0  million  in  future  contingent  development,  regulatory  and  commercialization
milestones across all programs in the collaboration. the agreement may be terminated by us for convenience upon 12 months’
notice and may also be terminated under certain other circumstances, including material breach. in 2018, we paid agenus a $5.0
million development milestone for the laG-3 program and a $5.0 million development milestone for the tim-3 program, which
were recorded in research and development expense on the consolidated statement of operations for the year ended December 31,
2018.

in connection with the amended agreement, we also agreed  to purchase 10.0 million  shares of agenus inc. common
stock for an aggregate purchase price of $60.0 million in cash, or $6.00 per share.  We completed the purchase of the shares on
February 14, 2017, when the closing price on the nasdaq Stock market for agenus inc. shares was $4.40 per share.  the shares
we  acquired  were  not  registered  under  the  Securities  act  of  1933  on  the  purchase  date  and  were  subject  to  certain  security
specific restrictions for a period of time, and accordingly, we estimated a discount for lack of marketability on the shares on the
issuance date of $4.5 million, which resulted in a net fair value of the shares on the issuance date of $39.5 million. therefore, of
the total consideration paid of $60.0 million, $39.5 million was allocated to our stock purchase in agenus inc. and was recorded
within long term investments and $20.5 million was allocated to research and development expense.

We  concluded  agenus  inc.  is  not  a  viE  because  it  has  sufficient  equity  to  finance  its  activities  without  additional
subordinated  financial  support  and  its  at-risk  equity  holders  have  the  characteristics  of  a  controlling  financial  interest.  after
completion  of  our  stock  purchases  from  agenus  inc.,  we  held  an  approximate  ownership  interest  of  18%  and,  under
circumstances  present  at  that  time,  concluded  that  we  had  the  ability  to  exercise  significant  influence,  but  not  control,  over
agenus inc., primarily due to the level of intra-entity transactions between us and agenus related to development expenses, as
well  as  other  qualitative  factors.  in  the  second  quarter  of  2020,  we  sold  an  aggregate  of  approximately  1.2  million  shares  of
agenus inc. common stock, reducing our ownership interest to approximately 9.8% as of June 30, 2020. the sales transactions
were  priced  at  market,  with  per  share  pricing  ranging  from  $3.57  to  $4.21,  resulting  in  gross  proceeds  of  approximately  $4.5
million.  in the third quarter  of 2020, we sold an aggregate  of approximately  2.5 million  shares of agenus inc. common stock,
reducing our ownership interest to approximately 7% as of December 31, 2020. the sales transactions were priced at market, with
per share pricing ranging from $4.28 to $5.25, resulting in gross proceeds of approximately $12.7 million. as a result of having a
less than 10% ownership interest and the recent diversification  of agenus inc.’s development pipeline with other collaboration
partners,  we  concluded  that  we  no  longer  have  significant  influence  over  agenus  inc.  as  such,  we  no  longer  account  for  our
equity  investment  in  agenus  inc.  as  an  equity  method  investment  previously  accounted  for  under  the  fair  value  option.  We
account for our investment in agenus inc. at fair value, whereby the investment is marked to market through earnings in each
reporting period. For the years ended December 31, 2020, 2019 and 2018, we recorded an unrealized loss of $10.3 million, an
unrealized gain of $30.0 million and an unrealized loss of $15.6 million, respectively, based on the change in fair market value of
agenus  inc.’s  common  stock  during  these  periods.  the  fair  market  value  of  our  long  term  investment  in  agenus  inc.  as  of
December 31, 2020 and 2019 was $44.7 million and $72.3 million, respectively.

research and development expenses for the years ended December 31, 2020, 2019 and 2018, also included $0.0 million,

$1.5 million and $4.6 million, respectively, of development costs incurred pursuant to the agenus arrangement.

99

table of Contents

at December 31, 2020 and 2019, a total of $0.5 million and $1.6 million, respectively, of such costs were included in accrued and
other liabilities on the consolidated balance sheets.

Merus

in  December  2016,  we  entered  into  a  Collaboration  and  license  agreement  with  merus  n.v.  (“merus”).  under  this
agreement, which became effective in January 2017, the parties have agreed to collaborate with respect to the research, discovery
and  development  of  bispecific  antibodies  utilizing  merus’  technology  platform.    the  collaboration  encompasses  up  to  eleven
independent programs.  

the most advanced collaboration program is mCla-145, a bispecific antibody targeting pD-l1 and CD137, for which
we  received  exclusive  development  and  commercialization  rights  outside  of  the  united  States.  merus  retained  exclusive
development  and  commercialization  rights  in  the  united  States  to  mCla-145.    Each  party  will  share  equally  the  costs  of
mutually  agreed  global  development  activities  for  mCla-145,  and  fund  itself  any  independent  development  activities  in  its
territory.    merus  will  be  responsible  for  commercializing  mCla-145  in  the  united  States  and  we  will  be  responsible  for
commercializing it outside of the united States.    

in addition to receiving rights to mCla-145 outside of the united States, we received worldwide exclusive development
and  commercialization  rights  to  up  to  ten  additional  programs.  of  these  ten  additional  programs,  merus  retained  the  option,
subject to certain conditions, to co-fund development of up to two such programs. if merus exercises its co-funding option for a
program, merus would be responsible for funding 35% of the associated future global development costs and, for certain of such
programs,  would be responsible  for reimbursing  us for certain  development  costs incurred  prior  to the option exercise.   merus
will  also  have  the  right  to  participate  in  a  specified  proportion  of  detailing  activities  in  the  united  States  for  one  of  those  co-
developed  programs.  all  costs  related  to  the  co-funded  collaboration  programs  are  subject  to  joint  research  and  development
plans and overseen by a joint development committee, but we will have final determination as to such plans in cases of dispute.
 We will be responsible for all research, development and commercialization costs relating to all other programs.  

in February 2017, we paid merus an upfront non-refundable payment of $120.0 million. For each program as to which
merus does not have commercialization or development co-funding rights, merus will be eligible to receive up to $100.0 million
in future contingent development and regulatory milestones, and up to $250.0 million in commercialization milestones as well as
tiered royalties ranging from 6% to 10% of global net sales. For each program as to which merus exercises its option to co-fund
development, merus will be eligible to receive a 50% share of profits (or sustain 50% of any losses) in the united States and be
eligible to receive tiered royalties ranging from 6% to 10% of net sales of products outside of the united States.  if merus opts to
cease  co-funding  a  program  as  to  which  it  exercised  its  co-development  option,  then  merus  will  no  longer  receive  a  share  of
profits in the united States but will be eligible to receive the same milestones from the co-funding termination date and the same
tiered  royalties  described  above  with  respect  to  programs  where  merus  does  not  have  a  right  to  co-fund  development  and,
depending on the stage at which merus chose to cease co-funding development costs, merus will be eligible to receive additional
royalties ranging up to 4% of net sales in the united States.  For mCla-145, we and merus will each be eligible to receive tiered
royalties on net sales in the other party’s territory at rates ranging from 6% to 10%.  

the merus agreement will continue on a program-by-program basis until we have no royalty payment obligations with
respect  to  such  program  or,  if  earlier,  the  termination  of  the  agreement  or  any  program  in  accordance  with  the  terms  of  the
agreement.  the  agreement  may  be  terminated  in  its  entirety  or  on  a  program-by-program  basis  by  us  for  convenience.    the
agreement may also be terminated by either party under certain other circumstances, including material breach, as set forth in the
agreement.  if the agreement is terminated with respect to one or more programs, all rights in the terminated programs revert to
merus,  subject  to  payment  to  us  of  a  reverse  royalty  of  up  to  4%  on  sales  of  future  products,  if  merus  elects  to  pursue
development and commercialization of products arising from the terminated programs.  

in  addition,  in  December  2016,  we  entered  into  a  Share  Subscription  agreement  with  merus,  pursuant  to  which  we
agreed to purchase 3.2 million common shares of merus for an aggregate purchase price of $80.0 million in cash, or $25.00 per
share.  We  completed  the  purchase  of  the  shares  on  January  23, 2017  when  the  closing  price  on the  nasdaq  Stock  market  for
merus shares was $24.50 per share.  the shares we acquired were not registered under the Securities act

100

table of Contents

of 1933 on the purchase date and were subject to certain security specific restrictions for a period of time, and accordingly, we
estimated a discount for lack of marketability on the shares on the issuance date of $5.6 million, which resulted in a net fair value
of the shares on the issuance date of $72.8 million.  of the total consideration paid of $80.0 million, $72.8 million was allocated
to  our  stock  purchase  in  merus  and  was  recorded  as  a  long  term  investment  and  $7.2  million  was  allocated  to  research  and
development expense. the fair market value of our total long term investment in merus as of December 31, 2020 and 2019 was
$56.1  million  and  $45.1  million,  respectively.  in  January  2021,  we  purchased  350,000  common  shares  in  merus’  underwritten
public offering of 4,848,485 common shares at the public offering price of $24.75 per share, or an aggregate purchase price of
$8.7 million.

We concluded merus is not a viE because it has sufficient equity to finance its activities without additional subordinated
financial  support  and  its  at-risk  equity  holders  have  the  characteristics  of  a  controlling  financial  interest.  as  of  December  31,
2020,  we  owned  approximately  11%  of  the  outstanding  common  shares  of  merus  and  conclude  that  we  have  the  ability  to
exercise  significant  influence,  but  not  control,  over  merus  based  primarily  on  our  ownership  interest,  the  level  of  intra-entity
transactions between us and merus related to development expenses, as well as other qualitative factors.  We have elected the fair
value option to account for our long term investment in merus whereby the investment is marked to market through earnings in
each reporting period.  We believe the fair value option to be the most appropriate accounting method to account for securities in
publicly held collaborators for which we have significant influence. For the years ended December 31, 2020, 2019 and 2018, we
recorded  an  unrealized  gain  of  $11.0  million,  an  unrealized  gain  of  $0.3  million,  and  an  unrealized  loss  of  $17.3  million,
respectively, based on the change in fair market value of merus’ common shares during these periods.  

 research and development expenses for the years ended December 31, 2020, 2019 and 2018 included $8.9 million, $7.2
million and $10.3 million, respectively, of additional development costs incurred pursuant to the merus agreement. at December
31,  2020  and  2019,  a  total  of  $1.6  million  and  $1.6  million,  respectively,  of  such  costs  were  included  in  accrued  and  other
liabilities on the consolidated balance sheets.

Calithera

in January 2017, we entered into a Collaboration and license agreement with Calithera Biosciences, inc. (“Calithera”).
under  this  agreement,  we  received  an  exclusive,  worldwide  license  to  develop  and  commercialize  small  molecule  arginase
inhibitors, including inCB01158. We have agreed to co-fund 70% of the global development costs for the development of the
licensed products for hematology and oncology indications. Calithera will have the right to conduct certain clinical development
under the collaboration, including combination studies of a licensed product with a proprietary compound of Calithera. We will
be entitled to 60% of the profits and losses from net sales of licensed product in the united States, and Calithera will have the
right to co-detail licensed products in the united States, and we have agreed to pay Calithera tiered royalties ranging from the low
to mid-double digits on net sales of licensed products outside the united States.

in January 2017, we paid Calithera an upfront license fee of $45.0 million and have agreed to pay potential development,
regulatory and sales milestone payments of over $430.0 million if the profit share is in effect, or $750.0 million if the profit share
terminates.  in  2017,  Calithera  earned  a  $12.0  million  milestone  payment  from  us  for  the  achievement  of  pharmacokinetic  and
pharmacodynamics goals for CB-1158 which was recorded in research and development expense.

in august 2020, Calithera delivered notice of its decision to opt out of its co-funding obligation, effective on September 30,
2020.  as a result, the u.S. profit sharing will no longer be in effect, we will be responsible for funding all of the development
costs  of  inCB01158  and  any  other  licensed  products,  and  the  agreement  provides  that  we  will  pay  Calithera  tiered  royalties
ranging from the low to mid-double digits on net sales of licensed products both in the united States and outside the united States
and  additional  royalties  to  reimburse  Calithera  for  previously  incurred  development  costs.  in  addition,  the  total  remaining
potential development, regulatory and sales milestone payments will be $738.0 million and Calithera will have no further rights to
research,  develop  or  co-detail  inCB001158  and  we  will  have  the  right  to  take  over  the  conduct  of  all  activities  related  to  the
research, development and commercialization of inCB001158 for all indications in the hematology/oncology field.

table of Contents

the  Calithera  agreement  will  continue  on  a  product-by-product  and  country-by-country  basis  for  so  long  as  we  are
developing or commercializing products in the united States (if the parties are sharing profits in the united States) and until we
have no further  royalty payment obligations, unless earlier terminated  according to the terms of the agreement. the agreement
may  be  terminated  in  its  entirety  or  on  a  product-by-product  and/or  a  country-by-country  basis  by  us  for  convenience.  the
agreement may also be terminated by us for Calithera’s uncured material breach, by Calithera for our uncured material breach and
by either party for bankruptcy or patent challenge. if the agreement is terminated early with respect to one or more products or
countries, all rights in the terminated products and countries revert to Calithera.

in addition, in January 2017, we entered into a Stock purchase agreement with Calithera for the purchase of 1.7 million
common  shares  of  Calithera  for  an  aggregate  purchase  price  of  $8.0  million  in  cash,  or  $4.65  per  share.  We  completed  the
purchase of the shares on January 30, 2017 when the closing price on the nasdaq Stock market was $6.75 per share. the shares
we acquired were registered under the Securities act of 1933 on the purchase date and there were no security specific restrictions
for these shares, and therefore the value of the 1.7 million shares acquired by us was $11.6 million.  We paid total consideration
of $53.0 million to Calithera, composed of the $45.0 million upfront license fee and the $8.0 million stock purchase price. of the
$53.0 million, $11.6 million was allocated to our stock purchase in Calithera and was recorded within long term investments and
$41.4 million was allocated to research and development expense. the fair market value of our long term investment in Calithera
as of December 31, 2020 and 2019 was $8.4 million and $9.8 million, respectively.

We  concluded  Calithera  is  not  a  viE  because  it  has  sufficient  equity  to  finance  its  activities  without  additional
subordinated  financial  support  and  its  at-risk  equity  holders  have  the  characteristics  of  a  controlling  financial  interest.    as  of
December 31, 2020, we owned approximately 2% of the outstanding shares of Calithera common stock and there are several other
stockholders who hold larger positions of Calithera. as we do not hold a significant position of the voting shares of Calithera and
lack  the  qualitative  characteristics  associated  with  the  ability  to  exercise  significant  influence,  our  ownership  interest  does  not
meet  the  criteria  to  be  accounted  for  as  an  equity  method  investment.  We  intend  to  hold  the  investment  in  Calithera  for  the
foreseeable  future  and  therefore,  are  accounting  for  our  shares  held  in  Calithera  at  fair  value,  and  the  investment  is  marked  to
market  through  earnings  in  each  reporting  period.  Given  our  intent  to  hold  the  investment  for  the  foreseeable  future,  we  have
classified  the  investment  within  long  term  investments  on  the  accompanying  consolidated  balance  sheets.  For  the  years  ended
December 31, 2020, 2019 and 2018, we recorded an unrealized loss of $1.4 million, an unrealized gain of $2.9 million, and an
unrealized loss of $7.5 million, respectively, based on the change in fair market value of Calithera’s common stock during these
periods.  

research and development expenses for the years ended December 31, 2020, 2019 and 2018 also included $8.9 million,
$17.9 million and $12.0 million, respectively, of additional development costs incurred pursuant to the Calithera agreement. at
December 31, 2020 and 2019, a total of $0.6 million and $1.1 million, respectively, of such costs were included in accrued and
other liabilities on the consolidated balance sheets.

MacroGenics

in  october  2017,  we  entered  into  a  Global  Collaboration  and  license  agreement  with  macroGenics,  inc.
(“macroGenics”).  under  this  agreement,  we  received  exclusive  development  and  commercialization  rights  worldwide  to
macroGenics’ inCmGa0012 (formerly mGa012), an investigational monoclonal antibody that inhibits pD-1. Except as set forth
in the succeeding sentence, we will have sole authority over and bear all costs and expenses in connection with the development
and  commercialization  of  inCmGa0012  in  all  indications,  whether  as  a  monotherapy  or  as  part  of  a  combination
regimen.  macroGenics  has  retained  the  right  to  develop  and  commercialize,  at  its  cost  and  expense,  its  pipeline  assets  in
combination  with  inCmGa0012.    in  addition,  macroGenics  has  the  right  to  manufacture  a  portion  of  both  companies’  global
clinical and commercial supply needs of inCmGa0012. in 2017, we paid macroGenics an upfront payment of $150.0 million,
which was recorded in research and development expense. macroGenics was initially eligible to receive up to $420.0 million in
future  contingent  development  and  regulatory  milestones  and  up  to  $330.0  million  in  commercial  milestones  as  well  as  tiered
royalties ranging from 15% to 24% of global net sales.

in 2020, we paid macroGenics $40.0 million in milestones for the achievement of certain clinical milestones as part of
our  collaboration  and  license  agreement,  which  were  recorded  in  research  and  development  expense  on  our  consolidated
statement of operations for the year ended December 31, 2020. in 2018, we paid macroGenics a $10.0 million

102

table of Contents

and a $5.0 million milestone for the achievement of certain clinical milestones as part of our collaboration and license agreement,
which  were  recorded  in  research  and  development  expense  on  our  consolidated  statement  of  operations  for  the  year  ended
December 31, 2018.

the  macroGenics  agreement  will  continue  until  we  are  no  longer  commercializing,  developing  or  manufacturing
inCmGa0012 or, if earlier, the termination of the agreement in accordance with its terms.  the agreement may be terminated in
its entirety or on a licensed product by licensed product basis by us for convenience.  the agreement may also be terminated by
either party under certain other circumstances, including material breach, as set forth in the agreement.

research  and  development  expenses  for  the  years  ended  December  31,  2020,  2019  and  2018,  also  included  $59.0
million,  $51.1  million  and  $35.4  million,  respectively,  of  additional  development  costs  incurred  pursuant  to  the  macroGenics
agreement. at December 31, 2020 and 2019, a total of $0.1 million and $1.0 million, respectively, of such costs were included in
accrued and other liabilities on the consolidated balance sheets.

Syros

in  January  2018,  we  entered  into  a  target  discovery,  research  collaboration  and  option  agreement  with  Syros
pharmaceuticals,  inc.  (“Syros”).  under  this  agreement,  Syros  will  use  its  proprietary  gene  control  platform  to  identify  novel
therapeutic  targets  with  a  focus  in  myeloproliferative  neoplasms  and  we  have  received  options  to  obtain  exclusive  worldwide
rights to intellectual property resulting from the collaboration for up to seven validated targets. We will have exclusive worldwide
rights to develop and commercialize any therapies under the collaboration that modulate those validated targets. We have agreed
to pay Syros up to $54.0 million in target selection and option exercise fees should we decide to exercise all of our options under
the  agreement.  For  products  resulting  from  the  collaboration  against  each  of  the  seven  selected  and  validated  targets,  we  have
agreed to pay up to $50.0 million in potential development and regulatory milestones and up to $65.0 million in potential sales
milestones. Syros is also eligible to receive low single-digit royalties on net sales of products resulting from the collaboration. in
January  2018,  we  paid  Syros  an  upfront  non-refundable  (except  in  the  event  of  a  material  breach  of  the  agreement  by  Syros)
payment of $10.0 million, which was recorded in research and development expense on our consolidated statement of operations
for the year ended December 31, 2018.

in addition, in January 2018, we entered into a Stock purchase agreement with Syros for the purchase of 0.8 million
common shares of Syros for an aggregate purchase price of $10.0 million in cash, or $12.61 per share.  We agreed to not sell or
otherwise transfer any of our Syros shares for a period, referred to as the lock-up period, of 12 months after the closing date of
the sale. We completed the purchase of the shares on January 8, 2018 when the closing price on the nasdaq Stock market was
$9.77 per share. the shares we acquired were not registered on the purchase date, and accordingly, we estimated a discount for
lack of marketability on the shares of $0.1 million, which resulted in a net fair value of the shares on the issuance date of $7.6
million. of the $10.0 million aggregate purchase price paid, $7.6 million was allocated to our stock purchase in Syros and was
recorded within long term investments and $2.4 million, representing premium paid on the purchase, was allocated to research
and  development  expense  on  the  consolidated  statement  of  operations  for  the  year  ended  December  31,  2018.  also in  January
2018, we entered into an amended Stock purchase agreement with Syros for the purchase of an additional 0.1 million common
shares of Syros for an aggregate purchase price of $1.4 million in cash, or $9.55 per share.  the shares were acquired in February
2018  and  the  $1.4  million  aggregate  purchase  price  was  recorded  within  long  term  investments  on  the  consolidated  balance
sheets. all acquired shares were subsequently registered under the Securities act of 1933 in February 2018. the fair market value
of our long term investment in Syros as of December 31, 2020 and 2019 was $10.2 million and $6.5 million, respectively.

We concluded Syros is not a viE because it has sufficient equity to finance its activities without additional subordinated
financial  support  and  its  at-risk  equity  holders  have  the  characteristics  of  a  controlling  financial  interest.    as  of  December  31,
2020,  we  owned  approximately  2%  of  the  outstanding  shares  of  Syros  common  stock  and  there  are  several  other  stockholders
who hold larger positions of Syros. as we do not hold a significant position of the voting shares of Syros and lack the qualitative
characteristics associated with the ability to exercise significant influence, our ownership interest does not meet the criteria to be
accounted for as an equity method investment. We intend to hold the investment in Syros for the foreseeable future and therefore,
are  accounting  for  our  shares  held  in  Syros  at  fair  value,  and  the  investment  is  marked  to  market  through  earnings  in  each
reporting period.  Given our intent to hold the investment for the foreseeable

103

table of Contents

future, we have classified the investment within long term investments on the accompanying consolidated balance sheets. For the
years  ended  December  31,  2020,  2019  and  2018,  we  recorded  an  unrealized  gain  of  $3.7  million,  an  unrealized  gain  of  $1.3
million and an unrealized  loss of $3.7 million, respectively,  based on the change in fair market value of Syros’ common stock
during these periods.  

Innovent

in December 2018, we entered into a research collaboration and licensing agreement with innovent. under the terms of
this agreement, innovent received exclusive development and commercialization rights to our clinical-stage product candidates
pemigatinib,  itacitinib  and  parsaclisib  in  hematology  and  oncology  in  mainland  China,  hong  Kong,  macau  and  taiwan.  in
January  2019,  we  recognized  an  upfront  payment  under  this  agreement  of  $40.0  million  upon  our  transfer  of  the  functional
intellectual  property  related  to the clinical-stage  product candidates  to innovent, which was recorded  in milestone  and contract
revenues  on  the  consolidated  statement  of  operations  for  the  year  ended  December  31,  2019.  the  upfront  milestone  was
recognized as revenue at a point in time upon our transfer of the licenses to innovent for the right to use the functional intellectual
property.  in  addition,  we  were  initially  eligible  to  receive  up  to  an  additional  $129.0  million  in  potential  development  and
regulatory milestones.

We recognize development and regulatory milestones upon confirmation of achievement of the event, as development
and regulatory approvals are events not controllable by us but rather development activities of innovent and decisions made by
regulatory agencies. in 2020, we recognized a $5.0 million milestone for the FDa approval of pemigatinib as pEmaZYrE. in
2019, we recognized the $20.0 million milestone for the first related inD filing in China.

in the event of commercialization of the licensed molecule, we are eligible to receive up to $202.5 million in potential
sales  milestones  from  innovent.  We  will  recognize  sales  milestones  in  the  corresponding  period  of  the  product  sale  upon
confirmation of net sales milestone threshold achievement by innovent. We are also eligible to receive tiered royalties from the
high-teens  to the low-twenties  on future  sales of products resulting  from the collaboration.  We retain  an option to assist in the
promotion of the three product candidates in the innovent territories.

research and development expenses for the years ended December 31, 2020 and 2019 were net of $5.4 million and $6.2
million,  respectively,  of  costs  reimbursed  by  innovent.  at  December  31,  2020  and  2019,  $1.2  million  and  $3.0  million,
respectively, of reimbursable costs were included in accounts receivable on the consolidated balance sheets.

Zai Lab

in July 2019, we entered into a collaboration and license agreement with Zai lab. under the terms of this agreement, Zai
lab  received  development  and  exclusive  commercialization  rights  to  inCmGa0012  in  hematology  and  oncology  in  mainland
China,  hong  Kong,  macau  and  taiwan.  in  august  2019,  we  recognized  an  upfront  payment  under  this  agreement  of  $17.5
million upon our transfer of the functional intellectual property related to the licensed product candidate to Zai lab, which was
recorded in milestone and contract revenues on the consolidated statement of operations for the year ended December 31, 2019.
the upfront milestone was recognized as revenue at a point in time upon our transfer of the license to Zai lab for the right to use
the functional intellectual property.

the agreement allows for Zai lab to continue development of the licensed molecule and to submit the licensed molecule
to  authorities  for  regulatory  approval  within  the  agreement  territory,  upon  which  we  are  eligible  for  up  to  $22.5  million  in
potential  development  and  regulatory  milestones.  We  recognize  development  and  regulatory  milestones  upon  confirmation  of
achievement  of  the  event,  as  development  and  regulatory  approvals  are  events  not  controllable  by  us  but  rather  development
activities of Zai lab and decisions made by regulatory agencies.

in the event of commercialization of the licensed molecule, we are eligible to receive up to $37.5 million in potential
sales  milestones  from  Zai  lab.  We  will  recognize  sales  milestones  in  the  corresponding  period  of  the  product  sale  upon
confirmation of net sales milestone threshold achievement by Zai lab. We are also eligible to receive tiered royalties from the
low to mid-twenties on future product sales resulting from the collaboration. We also retain an option to assist in the promotion of
inCmGa0012 in Zai lab’s licensed territories.

research and development expenses for the year ended December 31, 2020 were net of $0.2 million of costs reimbursed
by Zai lab. at December 31, 2020 and 2019, $0.6 million and $0.5 million, respectively, of reimbursable costs were included in
accounts receivable on the condensed consolidated balance sheets.

MorphoSys

in January 2020, we entered into a Collaboration and license agreement with morphoSys aG and morphoSys uS inc.,
a  wholly-owned  subsidiary  of  morphoSys  aG  (together  with  morphoSys  aG,  “morphoSys”),  covering  the  worldwide
development  and  commercialization  of  mor208  (tafasitamab),  an  investigational  Fc  engineered  monoclonal  antibody  directed
against the target molecule CD19 that is currently in clinical development by morphoSys. morphoSys has exclusive worldwide
development and commercialization rights to tafasitamab under a June 2010 collaboration and license agreement with xencor,
inc. in December 2019, morphoSys submitted a Biologics license application to the FDa for tafasitamab for the treatment of
relapsed  or  refractory  diffuse  large  B  cell  lymphoma.    the  agreement  became  effective  in  march  2020  after  clearance  by  the
German  and  austrian  antitrust  authorities  and  expiration  of  the  waiting  period  under  the  hart-Scott  rodino  antitrust
improvements act of 1976.

under  the  terms  of  the  agreement,  we  received  exclusive  commercialization  rights  outside  of  the  united  States,  and
morphoSys and we have co-commercialization rights in the united States, with respect to tafasitamab.  morphoSys is responsible
for leading the commercialization strategy and booking all revenue from sales of tafasitamab in the united States, and we and
morphoSys are both responsible for commercialization efforts in the united States and will share equally the profits and losses
from  the  co-commercialization  efforts.  We  will  lead  the  commercialization  strategy  outside  of  the  united  States,  and  will  be
responsible for commercialization efforts and book all revenue from sales of tafasitamab outside of the united States, subject to
our  royalty  payment  obligations  set  forth  below.  We  and  morphoSys  have  agreed  to  co-develop  tafasitamab  and  to  share
development  costs  associated  with  global  and  u.S.-specific  clinical  trials,  with  incyte  responsible  for  55%  of  such  costs  and
morphoSys responsible for 45% of such costs.  Each company is responsible for funding any independent development activities,
and  we  are  responsible  for  funding  development  activities  specific  to  territories  outside  of  the  united  States.  all  development
costs related to the collaboration are subject to a joint development plan.  

in  march  2020,  we  paid  morphoSys  an  upfront  non-refundable  payment  of  $750.0  million  which  was  recorded  in
research  and  development  expense  on  the  consolidated  statement  of  operations  for  the  year  ended  December  31,  2020.
morphoSys  is  eligible  to  receive  up  to  $740.0  million  in  future  contingent  development  and  regulatory  milestones  and  up  to
$315.0 million in commercialization milestones as well as tiered royalties ranging from the mid-teens to mid-twenties of net sales
outside of the united States. morphoSys’ right to receive royalties in any particular country will expire upon the last to occur of
(a)  the  expiration  of  patent  rights  in  that  particular  country,  (b)  a  specified  period  of  time  after  the  first  post-marketing
authorization  sale  of  a  licensed  product  comprising  tafasitamab  in  that  country,  and  (c)  the  expiration  of  any  regulatory
exclusivity for that licensed product in that country.

in  July  2020,  we  and  morphoSys  announced  that  the  FDa  approved  monJuvi®  (tafasitamab-cxix)  in  combination
with  lenalidomide  for  the  treatment  of  adult  patients  with  relapsed  or  refractory  diffuse  large  B-cell  lymphoma  (DlBCl)  not
otherwise  specified,  including  DlBCl  arising  from  low  grade  lymphoma,  and  who  are  not  eligible  for  autologous  stem  cell
transplant. monJuvi was approved under accelerated approval based on overall response rate.

in  addition,  under  the  collaboration  agreement  and  pursuant  to  a  related  purchase  agreement,  we  agreed  to  purchase
american Depositary Shares (“aDSs”), each representing 0.25 of an ordinary share of morphoSys aG, for an aggregate purchase
price  of  $150.0  million  or  $41.33  per  aDS  (such  aDSs  to  be  purchased,  the  “new  aDSs”).  We  agreed,  subject  to  limited
exceptions, not to sell or otherwise transfer any of the new aDSs for an 18-month period after the closing date of the sale. We
completed the purchase of the aDSs on march 3, 2020 when the closing price on the nasdaq Stock market was $27.65 per aDS.
the  new  aDSs  were  not  registered  under  the  Securities  act  of  1933  on  the  purchase  date,  and  accordingly,  we  estimated  a
discount for lack of marketability on the shares of $4.9 million, which resulted in a net fair value of the shares on the issuance
date of $95.5 million. of the $150.0 million aggregate purchase price paid, $95.5 million was allocated to our stock purchase in
morphoSys and was recorded within long term investments and $54.5 million, representing the premium paid on the purchase,
was  allocated  to  research  and  development  expense.  the  fair  market  value  of  our  long  term  investment  in  morphoSys  as  of
December 31, 2020 was $102.9 million.

105

table of Contents

We  concluded  morphoSys  is  not  a  viE  because  it  has  sufficient  equity  to  finance  its  activities  without  additional
subordinated  financial  support  and  its  at-risk  equity  holders  have  the  characteristics  of  a  controlling  financial  interest.    as  of
December 31, 2020, we owned approximately 3% of the outstanding shares of morphoSys common stock and there are several
other  stockholders  who  hold  larger  positions  of  morphoSys.    as  we  do  not  hold  a  significant  position  of  the  voting  shares  of
morphoSys  and  lack  the  qualitative  characteristics  associated  with  the  ability  to  exercise  significant  influence,  our  ownership
interest  does  not  meet  the  criteria  to  be  accounted  for  as  an  equity  method  investment.  We  intend  to  hold  the  investment  in
morphoSys  for  the  foreseeable  future  and  therefore,  are  accounting  for  our  shares  held  in  morphoSys  at  fair  value,  and  the
investment  is  marked  to  market  through  earnings  in  each  reporting  period.    Given  our  intent  to  hold  the  investment  for  the
foreseeable  future,  we  have  classified  the  investment  within  long  term  investments  on  the  accompanying  consolidated  balance
sheets. For the year ended December 31, 2020, we recorded an unrealized gain of $7.4 million based on the change in fair market
value of morphoSys’ common stock during the period.  

our 50% share of the united States loss for the commercialization of tafasitamab was $42.8 million for the year ended
December  31,  2020  and  is  recorded  as  collaboration  loss  sharing  on  the  consolidated  statement  of  operations.  research  and
development  expenses  for  the  year  ended  December  31,  2020,  included  $88.2  million  related  to  our  55%  share  of  the  co-
development  costs  for  tafasitamab.  at  December  31,  2020,  $54.2  million  was  included  in  accrued  and  other  liabilities  on  the
consolidated balance sheet for amounts due to morphoSys under the agreement.

Nimble

in September 2020, we entered into a collaboration and license agreement with nimble therapeutics, inc. (“nimble”).
under the terms of this agreement, nimble will utilize their peptide synthesis, screening and optimization platform for discovery
and validation of peptides against specified targets. under the agreement, nimble is eligible to receive up to $8.0 million in future
contingent  discovery  milestones  and  up  to  $127.0  million  in  future  contingent  development  and  regulatory  milestones.
additionally, in the event of successful commercialization, nimble is eligible to receive up to $130.0 million in future contingent
sales milestones and tiered royalties on net sales in the low single digits.

Depreciation expense, including amortization expense of leasehold improvements, was $29.6 million, $32.1 million and

$32.3 million for the years ended December 31, 2020, 2019 and 2018, respectively.

in march 2017, we acquired additional adjacent buildings to our global headquarters in Wilmington, Delaware and in
2019,  began  demolition  of  these  buildings  and  construction  of  a  new  laboratory  and  office  building  totaling  approximately
200,000 square feet. as of December 31, 2020, we have capitalized  approximately $79.5 million in on site preparation, design
and construction costs and currently expect the building to be completed in the second half of 2021.

in February 2018, we signed an agreement to rent a building in morges, Switzerland for an initial term of 15 years plus

one year of free rent, with multiple options to extend for an additional 20 years. the building serves as our new

106

    
    
 
 
 
 
 
 
 
 
 
table of Contents

European headquarters and consists of approximately 100,000 square feet of office space. this building allowed for consolidation
of  our  European  operations  that  were  located  in  Geneva  and  lausanne,  Switzerland.  in  June  2019,  we  obtained  control  of  the
morges building to begin our construction activity, which was completed in 2020. at that time, we determined the lease to be a
finance lease and recorded a lease liability of $31.1 million and a finance lease right-of-use asset of $29.1 million, net of a lease
incentive  from  our  landlord  of  $2.0  million.  as  of  December  31,  2020,  we  have  capitalized  approximately  $17.9  million  in
leasehold improvements.

in  July  2018,  we  signed  an  agreement  to  purchase  land  located  in  Yverdon,  Switzerland.  the  land  was  purchased,  in
cash,  for  approximately  $4.8  million.  upon  this  parcel,  we  are  constructing  a  large  molecule  production  facility.  Construction
activity commenced in July 2018, and as of December 31, 2020, we have capitalized approximately $167.4 million in costs for
construction, ground preparation and architectural and engineering studies. We currently expect the facility will be operational in
the second half of 2021.

We  are  the  lessee  of  several  contracts,  including  those  to  secure  fleet  vehicles,  buildings  and  equipment.  our  lease
agreements  do not contain any material  residual  value guarantees  or restrictive  covenants. Some of our building leases include
options  to  renew  and  the  exercise  of  these  options  is  at  our  discretion.  our  current  operating  lease  liabilities  are  reflected  in

the cash paid for amounts included in the measurement of our operating lease liabilities for the years ended December
31, 2020 and 2019 was $12.1 million and $11.9 million, respectively, in operating cash flows. the cash paid for amounts included
in the measurement of our finance lease liabilities for the years ended December 31, 2020 and 2019 was $0.8 million in financing
cash flows.

as of December 31, 2020, our finance and operating leases had a weighted average lease term of approximately 14.2 and
4.7  years,  respectively.  the  discount  rate  of  our  leases  is  an  approximation  of  an  estimated  incremental  borrowing  rate  and  is
dependent  upon  the  term  and  economics  of  each  agreement.  the  weighted  average  discount  rate  of  our  finance  and  operating
leases is approximately 3.7% and 4.7%, respectively. as of December 31, 2019, our finance and operating leases had a weighted
average lease term of approximately 15.8 and 3.0 years, respectively, and the weighted average discount rate of our finance and

the fair value as of December 31, 2019 of the 1.25% Convertible Senior notes that matured on november 15, 2020 (the
“2020  notes”)  was  based  on  data  from  readily  available  pricing  sources  which  utilize  market  observable  inputs  and  other
characteristics for similar types of instruments, and, therefore, is classified within level 2 in the fair value hierarchy.

prior  to  may  14,  2014,  the  2020  notes  were  not  convertible  except  in  connection  with  a  make-whole  fundamental
change,  as  defined  in  the  indenture.  Beginning  on,  and  including,  may  15,  2014,  the  2020  notes  were  convertible  prior  to  the
close of business on the business day immediately preceding may 15, 2020 only under the following circumstances:  (i) during
any calendar quarter commencing after the calendar quarter ending on march 31, 2014 (and only during such calendar quarter), if
the last reported sale price of our common stock for at least 20 trading days (whether or not consecutive) during a period of  30
consecutive trading days ending on the last trading day of the immediately preceding calendar quarter is greater than or equal to
130% of the conversion price for the 2020 notes on each applicable trading day; (ii) during the five business day period after any
five  consecutive  trading  day  period  (the  “measurement  period”)  in  which  the  trading  price  per  $1,000  principal  amount  of  the
2020 notes for each trading day of the measurement period was less than 98% of the product of the last reported sale price of our
common  stock  and  the  conversion  rate  for  the  2020  notes  on  each  such  trading  day;  or  (iii)  upon  the  occurrence  of  specified
corporate events. on or after may 15, 2020 until the close of business on the second scheduled trading day immediately preceding
the maturity date, the 2020 notes were convertible at any time, regardless of the foregoing circumstances. upon conversion we
had  the  option  to  pay  or  deliver,  as  the  case  may  be,  cash,  shares  of  common  stock  or  a  combination  of  cash  and  shares  of
common stock.

the  initial  conversion  rate  for  the  2020  notes  was  19.3207  shares  of  common  stock  per  $1,000  principal  amount,

equivalent to an initial conversion price of approximately $51.76 per share.

prior to  maturity  on november  15, 2020, we settled,  upon conversion,  the remaining  2020 notes principal  balance  in

shares of common stock.

in July 2016, we revised the terms of our annual stock option grants to provide that new option grants would generally
have a 10-year term  and vest over four years,  with 25% vesting  after  one year  and the remainder  vesting  in  36 equal monthly
installments.  previously,  our option  grants  generally  had  7-year  terms  and  vested  over  three  years,  with  33%  vesting  after  one
year and the remainder vesting in 24 equal monthly installments.

options  to  purchase  a  total  of  6,732,942,  6,896,492  and  7,194,171  shares  as  of  December  31,  2020,  2019  and  2018,
respectively, were exercisable. the aggregate intrinsic value of options exercised for the years ended December 31, 2020, 2019
and 2018 were $87.5 million, $113.8 million and $73.9 million, respectively. at December 31, 2020, the aggregate intrinsic value

Restricted Stock Units and Performance Shares

in January 2014, we began granting restricted stock units (“rSus”) and performance shares (“pSus”) to our employees
at  the  share  price  on  the  date  of  grant.  Each  rSu  represents  the  right  to  acquire  one  share  of  our  common  stock.  Each  rSu
granted prior to July 2016 was subject to cliff vesting after three years. in July 2016, we revised the terms of our rSu grants to
provide that the awards will vest 25% annually over four years.

in June 2018, we granted 190,000 rSus and 446,500 pSus under long term incentive plans with performance  and/or
service-based  milestones  with  graded  and/or  cliff  vesting  over  three to  four  years.  in  april  2019,  we  granted  an  additional
100,000 pSus under one of the existing long term incentive plans with performance based milestones and cliff vesting. For one of
the existing long term incentive plans, under which 106,500 pSus were granted, the actual number of shares of our common stock
into  which  each  pSu  may  convert  was  subject  to  a  multiplier  of  up  to  267%  based  on  the  level  at  which  the  performance
conditions were achieved. the actual number of shares of our common stock into which each pSu will convert is at a multiplier
of 142% based on the performance conditions being achieved as of march 31, 2019 and

will continue to vest through June 2022.  For an existing long term incentive plan, under which 150,000 pSus were granted, the
actual number of shares of our common stock into which each pSu may convert was subject to a multiplier of up to 100% if all
performance  conditions were achieved or 0% if no performance  conditions were achieved. the actual  number of shares of our
common stock into which each pSu will convert is at a multiplier of 100% based on the performance conditions being achieved
as of December 31, 2019 and will cliff vest in June 2021. Compensation expense for the performance-based awards is recorded
over the estimated service period for each milestone when the performance conditions are deemed probable of achievement. For
the period ended December 31, 2020, the stock compensation expense recorded during the period was for service-based awards
and  performance  conditions  deemed  probable  of  achievement  and/or  achieved.  For  pSus  containing  performance  conditions
which were not deemed probable of achievement at December 31, 2020, no stock compensation expense was recognized.

in July 2018, we granted 77,243 pSus to executives with performance milestones and graded vesting over four years.
 the shares of our common stock into which each pSu may convert is subject to a multiplier up to 150% based on the level at
which  the  performance  condition  is  achieved.  Compensation  expense  for  the  performance-based  awards  is  recorded  over  the
estimated service period when the performance condition is deemed probable of achievement. the actual number of shares of our
common stock into which each pSu converted was at a multiplier of 83% based on the performance condition being achieved as
of December 31, 2018. these pSus will continue to vest through July 2022.

in July 2019, we granted 86,975 pSus to executives with a performance milestone and graded vesting over four years.
 the shares of our common stock into which each pSu may convert is subject to a multiplier up to 125% based on the level at
which  the  performance  condition  is  achieved.  Compensation  expense  for  the  performance-based  awards  is  recorded  over  the
estimated service period when the performance condition is deemed probable of achievement. the actual number of shares of our
common stock into which each pSu will convert is at a multiplier of 101.8% based on the performance condition being achieved
as of December 31, 2019.  these pSus will continue to vest through July 2023.

in  July  2020,  we  granted  92,347  pSus  to  executives  with  performance  milestones  and  cliff  vesting  on  the  third
anniversary from date of grant.  the shares of our common stock into which each pSu may convert is subject to a multiplier up to
200% based on the level at which the financial and developmental performance conditions are achieved over the service period
which ends December 31, 2022. Compensation expense for the performance-based awards is recorded over the estimated service
period for each milestone when the performance conditions are deemed probable of achievement. For the period ended December
31, 2020, the stock compensation expense recorded during the period was for service-based awards and performance conditions
deemed probable of achievement and/or achieved. For pSus containing performance conditions which were not deemed probable
of achievement at December 31, 2020, no stock compensation expense was recognized.

Employee Stock Purchase Plan.  on may 21, 1997, our stockholders adopted the 1997 Employee Stock purchase plan,
which was most recently amended in april 2020 (the “ESpp”). Each regular full-time and part-time employee working 20 hours
or more per week is eligible to participate after one month of employment. We issued 258,453, 239,590 and 233,712 shares under
the  ESpp  in  2020,  2019  and  2018,  respectively.  For  the  years  ended  December  31,  2020,  2019  and  2018,  we  recorded  stock
compensation expense of $4.6 million, $3.4 million and $3.7 million, respectively, as the ESpp is considered compensatory under
the FaSB stock compensation rules. as of December 31, 2020, 945,478 shares remain available for issuance under the ESpp.

Note 12. Stock Compensation

We  recorded  $177.9  million,  $166.6  million  and  $148.2  million,  respectively,  of  stock  compensation  expense  for  the
years ended December 31, 2020, 2019 and 2018. Stock compensation expense within our consolidated statements of operations
included research and development expense for the years ended December 31, 2020, 2019 and 2018 of $120.4 million, $114.0
million  and  $101.1  million,  respectively.  Stock  compensation  expense  within  our  consolidated  statements  of  operations  also
included  selling,  general  and administrative  expense  for  the years  ended December  31, 2020, 2019 and 2018 of $56.6 million,
$51.9 million and $47.1 million, respectively. Stock compensation expense within our consolidated statements of operations also
included cost of product revenues for the years ended December 31, 2020 and 2019 of $1.0 million and $0.7 million respectively.
For the years ended December 31, 2020, 2019 and 2018, we capitalized $0.6 million, $0.4 million and $0.1 million, respectively,
of stock compensation expense as part of the cost of an asset.  

We  utilized  the  Black-Scholes  valuation  model  for  estimating  the  fair  value  of  the  stock  options  granted,  with  the

following weighted-average assumptions:

average risk-free interest rates
average expected life (in years)
volatility
Weighted-average fair value (in dollars)

the risk-free interest rate is derived from the u.S. Federal reserve rate in effect at the time of grant. the expected life
calculation is based on the observed and expected time to the exercise of options by our employees based on historical exercise
patterns  for  similar  type  options.  Expected  volatility  is  based  on  the  historical  volatility  of  our  common  stock  over  the  period
commensurate with the expected life of the options. a dividend yield of zero is assumed based on the fact that we have never paid
cash  dividends  and  have  no  present  intention  to  pay  cash  dividends.  nonemployee  awards  are  measured  on  the  grant  date  by
estimating the fair value of the equity instruments to be issued using the expected term, similar to our employee awards.

Based on our historical experience of employee turnover, we have assumed an annualized forfeiture rate of 5% for our
options, pSus and rSus. under the true-up provisions of the stock compensation guidance, we will record additional expense as
the awards vest if the actual forfeiture rate is lower than we estimated, and will record a recovery of prior expense if the actual
forfeiture is higher than we estimated.

the  valuation  allowance  for  deferred  tax  assets  increased  by  approximately  $159.7  million  during  the  year  ended
December  31,  2020,  decreased  by  approximately  $66.5  million  during  the  year  ended  December  31,  2019  and  increased  by
approximately  $2.2 million during the year ended December 31, 2018.  the net valuation  allowance increase during 2020 was
primarily due to the generation of future deductible temporary differences and foreign nols offset by a net utilization of research
and development (“r&D”) and orphan drug credits in the u.S.

valuation allowances require an assessment of both positive and negative evidence when determining whether it is more
likely than not that deferred tax assets are recoverable.  Such assessment is required on a jurisdiction-by-jurisdiction basis.  the
ultimate realization of deferred tax assets is dependent upon the generation of future taxable income during the periods in which
those temporary differences become deductible.

Based upon our analysis of our historical operating results, as well as projections of our future taxable income (losses)
during  the  periods  in  which  the  temporary  differences  will  be  recoverable,  management  believes  the  uncertainty  regarding  the
realization of our u.S. and Swiss net deferred tax assets requires a full valuation allowance against such net assets as of December
31, 2020. When performing our assessment on projections of future taxable income (losses), we

114

  
  
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
table of Contents

consider factors such as the likelihood of regulatory approval and commercial success of products currently under development,
among other factors.  

the financial statement recognition of the benefit for a tax position is dependent upon the benefit being more likely than
not to be sustainable upon audit by the applicable taxing authority. if this threshold is met, the tax benefit is then measured and
recognized at the largest amount that is greater than 50% likely of being realized upon ultimate settlement. if such unrecognized
tax  benefits  were  realized  and  not  subject  to  valuation  allowances,  we  would  recognize  a  tax  benefit  of  $31.6  million.  the
following table summarizes the gross amounts of unrecognized tax benefits (in thousands):

our policy is to recognize interest and penalties related to uncertain tax positions, if any, as a component of income tax
expense. During the year ended December 31, 2020, we recorded a negligible reduction to interest and penalties as a component
of income tax expense.  During the years ending December 31, 2019 and 2018, we recorded interest and penalties as a component
of  income  tax  expense  of  $0.2  million  and  $0.1  million,  respectively.  We  do  not  anticipate  any  significant  changes  to  our
unrecognized tax benefits during the next twelve months.

the  Company  files  u.S.  federal,  state  and  local  income  tax  returns  and  income  tax  returns  in  various  foreign
jurisdictions, with statutes of limitation generally ranging from three to five years during which such tax returns may be audited
by the relevant tax authorities. those statutes could be extended due to nol or tax credit carryforwards generated during these
periods  that  are  subsequently  utilized  in  open  tax  periods.    in  general,  tax  authorities  have  the  ability  to  adjust  the  nol
carryforward or tax credits for three years after utilization of that year’s tax attribute carryforward.

Note 14. Net Income (Loss) Per Share

our basic net income (loss) per share is computed by dividing the net income (loss) by the number of weighted average
common shares outstanding during the period. our diluted net income (loss) per share is computed by dividing net income (loss)
by  the  weighted  average  common  shares  outstanding  during  the  period  assuming  potentially  dilutive  common  shares  of  stock
options, rSus, pSus and common shares issuable upon conversion of the 2020 notes using the if-converted method.  Common
shares issuable upon conversion of the 2020 notes were excluded from the diluted net income (loss) per share computation for all
periods presented as their share effect was anti-dilutive.

Note 15. Employee Benefit Plans

Defined Contribution Plans

We  have  a  defined  contribution  plan  qualified  under  Section  401(k)  of  the  internal  revenue  Code  covering  all  u.S.
employees and defined contribution plans for other incyte employees in Europe and Japan. Employees may contribute a portion
of  their  compensation,  which  is  then  matched  by  us,  subject  to  certain  limitations.  Defined  contribution  expense  was
$13.4 million, $11.7 million and $10.5 million for the years ended December 31, 2020, 2019 and 2018, respectively.  included in
the 2020, 2019 and 2018 defined contribution expense was $1.7 million, $1.6 million and $1.4 million, respectively, of expense
related to matching contributions under the non-u.S. defined contribution plans.

Defined Benefit Pension Plans

We  have  defined  benefit  pension  plans  for  our  employees  in  Europe  which  provide  benefits  to  employees  upon
retirement, death or disability. the assets of the pension plans are held in collective investment accounts represented by the cash
surrender value of an insurance policy and are classified as level 2 within the fair value hierarchy.

the pension plans assumptions reflect the expected investment return and discount rate on plan assets and disability rate
probabilities. the benefit obligation at December 31, 2020 for the plans was determined using a discount rate of 0.10% and rate
of  compensation  increase  of  2.00%.  the  2020  net  periodic  benefit  cost  for  the  plans  was  determined  using  discount  rates  of
0.30%, rates of compensation increase of 2.25% and long-term expected return on plan assets of 0.30%. the benefit obligation at
December 31, 2019 for the plans was determined using a discount rate of 0.30% and rate of compensation increase of 2.25%.  the
2019  net  periodic  benefit  cost  for  the  plans  was  determined  using  discount  rates  of  0.75%,  rates  of  compensation  increase  of
2.25% and long-term expected return on plan assets of 0.75%.

Note 16. Commitments and Contingencies

in  october  2019,  we  entered  into  an  agreement  with  Wilmington  Friends  School  inc.,  to  purchase  property  for  $50.0
million to expand our global headquarters.  under that agreement,  closing of the purchase is subject to certain standard closing
conditions, including an initial diligence period and a subsequent approval period. information on our future lease obligations are
described in note 7.

We  have  entered  into  the  collaboration  agreements  described  in  note  6,  as  well  as  various  other  collaboration
agreements that are not individually, or in the aggregate, significant to our operating results or financial condition at this time. We
may in the future seek to license additional rights relating to technologies or drug development candidates in connection with our
drug discovery and development programs. under these agreements, we may be required to pay upfront fees, milestone payments,
and royalties on sales of future products.

in  December  2018,  we  received  a  civil  investigative  demand  from  the  u.S.  Department  of  Justice  (“DoJ”)  for
documents and information relating to our speaker programs and patient assistance programs, including our support of non-profit
organizations that provide financial assistance to eligible patients. We have cooperated with this inquiry. in november 2019, the
qui tam complaint  underlying  the  DoJ  inquiry  was  unsealed  (“Complaint”),  at  which  time  we  learned  that  a  former  employee
whom we had terminated  had made  certain  allegations  relating  to the programs  described  above (“relator”).  the DoJ has not
intervened to date. We filed an answer to the Complaint on January 22, 2020 and on november 12, 2020, we filed a motion for
Summary Judgment (motion).  all briefing on the motion was completed on December 22, 2020 and the Judge will rule on the
motion based on these filings in due course.  a trial date has not been set.  We intend to continue defending ourselves vigorously
against these allegations. We cannot predict the outcome or the timing of the ultimate resolution of the investigation or qui tam
action, or reasonably estimate the possible range of loss, if any, that may result from these matters. accordingly, no reserve has
been made with respect to these matters as of December 31, 2020.  

in the ordinary course of our business, we may become involved in lawsuits, proceedings, and other disputes, including
commercial, intellectual property, regulatory, employment, and other matters.  We record a reserve for these matters when it is
both probable that a liability has been incurred and the amount of the loss can be reasonably estimated.

Item 9.  Changes in and Disagreements with Accountants on Accounting and Financial Disclosure

not applicable.

Item 9A.  Controls and Procedures

Evaluation of disclosure controls and procedures.  We maintain “disclosure controls and procedures,” as such term is
defined  in  rule  13a-15(e)  under  the  Securities  Exchange  act  of  1934  (the  “Exchange  act”),  that  are  designed  to  ensure  that
information  required  to  be  disclosed  by  us  in  reports  that  we  file  or  submit  under  the  Exchange  act  is  recorded,  processed,
summarized,  and  reported  within  the  time  periods  specified  in  Securities  and  Exchange  Commission  rules  and  forms,  and  that
such  information  is  accumulated  and  communicated  to  our  management,  including  our  Chief  Executive  officer  and  Chief
Financial  officer,  as  appropriate,  to  allow  timely  decisions  regarding  required  disclosure.  in  designing  and  evaluating  our
disclosure  controls  and  procedures,  management  recognized  that  disclosure  controls  and  procedures,  no  matter  how  well
conceived  and  operated,  can  provide  only reasonable,  not absolute,  assurance  that  the objectives  of  the disclosure  controls  and
procedures  are  met.  our  disclosure  controls  and  procedures  have  been  designed  to  meet  reasonable  assurance  standards.
additionally, in designing disclosure controls and procedures, our management necessarily was required to apply its judgment in
evaluating the cost-benefit relationship of possible disclosure controls and procedures. the design of any disclosure controls and
procedures also is based in part upon certain assumptions about the likelihood of future events, and there can be no assurance that
any design will succeed in achieving its stated goals under all potential future conditions.

Based on their evaluation as of the end of the period covered by this annual report on Form 10-K, our Chief Executive
officer and Chief Financial officer concluded that, as of such date, our disclosure controls and procedures were effective at the
reasonable assurance level.

Changes  in  internal  control  over  financial  reporting.   there  were  no  changes  in  our  internal  control  over  financial
reporting (as defined in rules 13a-15(f) and 15d-15(f) under the Exchange act) for the quarter ended December 31, 2020, that
materially affected or are reasonably likely to materially affect our internal control over financial reporting.

Management’s  annual  report  on  internal  control  over  financial  reporting.   our  management  is  responsible  for
establishing  and  maintaining  adequate  internal  control  over  financial  reporting,  as  such  term  is  defined  in  Exchange  act
rules  13a-15(f).  Because  of  its  inherent  limitations,  internal  control  over  financial  reporting  may  not  prevent  or  detect
misstatements. projections of any evaluation of the 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, with the participation of our Chief Executive officer and Chief Financial officer, conducted an evaluation of
the  effectiveness  of  our  internal  control  over  financial  reporting  based  on  the  framework  in  Internal  Control—Integrated
Framework issued by the Committee of Sponsoring organizations of the treadway Commission (2013 framework). Based on our
evaluation under the framework in Internal Control—Integrated Framework, our management concluded that our internal control
over financial reporting was effective as of December 31, 2020. the effectiveness of our internal control over financial reporting
as of December 31, 2020 has been audited by Ernst & Young llp, an independent registered public accounting firm, as stated in
their report which is included herein.

Report of Independent Registered Public Accounting Firm

to the Stockholders and the Board of Directors of incyte Corporation

Opinion on Internal Control over Financial Reporting

We have audited incyte Corporation’s internal control over financial reporting as of December 31, 2020, 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, incyte Corporation (the Company) maintained, in all material
respects, effective internal control over financial reporting as of December 31, 2020, 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 incyte Corporation as of December 31, 2020 and 2019, the related consolidated
statements of operations, comprehensive income (loss), stockholders’ equity and cash flows for each of the three years in the
period ended December 31, 2020, and the related notes and our report dated February 9, 2021 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.

such amount designated in integral multiples of one percent (1%); provided, however, that the aggregate of such payroll
deductions during any offering period shall not exceed ten percent (10%) of the participant’s aggregate Compensation
during such offering period. if required under applicable law or if specifically provided in the offering or otherwise
permitted by the administrator (and, with respect to the 423 Component, to the extent permitted under Section 423), in
addition to or instead of making contributions to the plan by payroll deductions, a participant may make contributions
through the payment by cash, check or wire transfer, provided that the same requirements and limitations shall apply in
the case of such other contributions and provided further that the administrator may establish any procedures it considers
to be necessary or advisable for the administration of the plan and, with respect to the 423 Component, the requirements
of Section 423. For purposes of the plan, references to “payroll deductions” includes such other contributions, if
applicable.

(b)

all payroll deductions made for a participant shall be credited to his or her account under the

plan and shall be withheld in whole percentages only. a participant may not make any additional payments into such
account.

(c)

a participant may discontinue his or her participation in the plan as provided in Section 10, 
or may increase or decrease the rate of his or her payroll deductions as provided in this Section 6(c). a participant may 
increase the rate of his or her payroll deductions only as of the beginning of a purchase period. Such increase shall take 
effect with the first payroll following the beginning of the new purchase period provided the participant has completed 
and delivered to the Company’s stock administrator a new subscription agreement authorizing the increase in the payroll 
deduction rate at least ten (10) business days prior to the beginning of the new purchase period (or indicated a change via 
the Company's electronic process according to the time frame indicated by the Company). a participant may decrease 
the rate of his or her payroll deductions each payroll period. any decrease shall become effective as of the first payroll 
period following the date that the participant completes and delivers to the Company’s stock administrator a new 
subscription agreement authorizing the decrease in the payroll deduction rate (or indicated a change via the Company's 
electronic process). however, if the subscription agreement is not received (or the electronic change is not completed) at 
least five (5) business days prior to such payroll period, the decrease shall become effective as of the second succeeding 
payroll period. the administrator may, in its discretion, limit the number of participation rate 

4

changes during any offering period. Subject to the foregoing, a participant’s subscription agreement (or electronic 
enrollment election) shall remain in effect for successive offering periods unless terminated as provided in Section 10 
hereof, provided that the participant will be deemed to have accepted the terms and conditions of the plan and the
offering in effect at the time each subsequent offering period begins.

(d)

notwithstanding the foregoing, to the extent necessary to comply with

Section 423(b)(8) of the Code and Section 3(b) hereof, a participant’s payroll deductions may be decreased to zero percent
(0%) at any time during a purchase period. Such a decrease shall not be treated as a withdrawal from the plan subject to
Section 10, unless the participant elects to withdraw pursuant to Section 10. payroll deductions shall recommence at the rate
provided in such participant’s subscription agreement at the beginning of the first purchase period which is scheduled to
end in the following calendar year, unless the participant elects to withdraw from the plan as provided in Section 10 hereof.

(e)

at the time the option is exercised, in whole or in part, or at the time some or all of the

Common Stock issued under the plan is disposed of, the participant must make adequate provision for the tax-related
items, if any, which arise upon the exercise of the option or the disposition of the Common Stock. at any time, the
Company or a Designated Subsidiary, as applicable, may, but shall not be obligated to, withhold from the participant’s
compensation the amount necessary to meet applicable withholding obligations, including any withholding required to
make available any tax deductions or benefits attributable to sale or early disposition of Common Stock by the Employee.

7.

Grant of option. on the Enrollment Date of each offering period, each eligible Employee participating in

such offering period shall be granted an option to purchase on each Exercise Date during such offering period (at the
applicable purchase price) up to a number of shares of Common Stock determined by dividing such Employee’s payroll
deductions accumulated prior to such Exercise Date and retained in the participant’s account as of the Exercise Date by
the applicable purchase price; provided that in no event shall an Employee be permitted to purchase during each purchase
period more than eight thousand (8,000) shares of Common Stock (subject to any adjustment pursuant to Section 18) on
the Enrollment Date, and provided further that such purchase shall be subject to the limitations set forth in Sections 3(b) 
and 13 hereof. Exercise of the option shall occur as provided in Section 8 hereof, unless the participant has withdrawn 
pursuant to Section 10 hereof. the option shall expire on the last day of the offering period.

8.

Exercise of option. unless a participant withdraws from the plan as provided in Section 10 hereof, his or

her option for the purchase of shares of Common Stock shall be exercised automatically on the Exercise Date, and the
maximum number of full shares of Common Stock subject to option shall be purchased for such participant at the
applicable purchase price with the accumulated payroll deductions in his or her account. no fractional shares shall be
purchased; any payroll deductions accumulated in a participant’s account which are not sufficient to purchase a full share
shall be, in the discretion of the administrator, either refunded to the participant or retained in the participant’s account for
the subsequent purchase period or offering period, subject to earlier withdrawal by the participant as provided in Section
10 hereof. any other monies left over in a participant’s account after the Exercise Date shall be returned to the participant.
During a participant’s lifetime, a participant’s option to purchase shares hereunder is exercisable only by him or her. if, on 
the Exercise Date, as delayed to the maximum extent permissible, the purchase of the shares of Common Stock would not 
be in material compliance with all applicable laws and regulations, as determined by the Company in its sole discretion, 
the option will not be exercised and any accumulated but unused payroll deductions will be refunded to the participant as 
soon as practicable.

9.

Delivery. as promptly as practicable after each Exercise Date on which a purchase of shares occurs, a share

certificate or certificates representing the number of shares of Common Stock so purchased shall be delivered to a
brokerage account designated by the Company and kept in such account pursuant to a subscription agreement between
each participant and the Company and subject to the conditions described therein which may include a requirement that
shares be held and not sold for certain time periods or be held with a designated broker and/or in a designated account, or
the Company shall establish some other means for such participants to receive ownership of the shares.

10. Discontinuation; Withdrawal.

5

(a)

a participant may discontinue his or her participation in the plan only by withdrawing from

the plan as provided in this Section 10. a participant may withdraw all but not less than all the payroll deductions credited
to his or her account and not yet used to exercise his or her option under the plan by giving written notice to the Company
(or by withdrawing from the plan via the electronic process available through the Company’s designated plan broker).
Such notice must be received by the Company or the plan broker no later than 5:00 p.m. Eastern time on the second
trading Day preceding the Exercise Date, or such other time preceding the Exercise Date as may be specified by the
Company or the plan broker, as applicable). all of the participant’s payroll deductions credited to his or her account shall
be paid to such participant promptly after receipt of a timely notice of withdrawal and such participant’s option for the
offering period shall be automatically terminated, and no further payroll deductions for the purchase of shares shall be
made for such offering period. if a participant withdraws from an offering period, payroll deductions shall not resume at
the beginning of the succeeding offering period unless the participant is an eligible Employee and that time and delivers
to the Company a new subscription agreement (or completes the electronic enrollment process) in accordance with Section
5(a).

a participant’s withdrawal from an offering period shall not have any effect upon his or her
eligibility to participate in any similar plan which may hereafter be adopted by the Company or in succeeding offering
periods which commence after the participant withdraws from the plan, subject to compliance with Section 5(a).

(b)

11. termination or transfer of Employment.

(a)

upon a participant’s ceasing to be an Employee, for any reason, he or she shall be deemed to 

have elected to withdraw from the plan and the payroll deductions credited to such participant’s account during the 
offering period but not yet used to exercise the option shall be returned to such participant or, in the case of his or her 
death, to the person or persons entitled thereto under Section 15 hereof, and such participant’s option shall be 
automatically terminated, unless otherwise required by applicable law.

(b)

unless otherwise determined by the administrator, a participant whose employment transfers 

or whose employment terminates with an immediate rehire (with no break in service) by or between the Company and a 
Designated Subsidiary that has been designated for participation in the plan will not be treated as having terminated 
employment for purposes of participating in the plan or an offering; however, if a participant transfers from an offering 
under the 423 Component to an offering under the non-423 Component, the exercise of the participant’s option to 
purchase Common Stock will be qualified under the 423 Component only to the extent such exercise complies with 
Section 423. if a participant transfers from an offering under the non-423 Component to an offering under the 423 
Component, the exercise of the option to purchase Common Stock will remain non-qualified under the non-423 
Component. the administrator may establish different and additional rules governing transfers between separate 
offerings within the 423 Component and between offerings under the 423 Component and offerings under the non-423 
Component.

12.

interest. no interest shall accrue on the payroll deductions of a participant in the plan or be payable or

otherwise due to the participant or his or her beneficiary, unless otherwise required by applicable law.

13. Stock.

(a)

the maximum number of shares of Common Stock which shall be made available for sale

under the plan shall be nine million six hundred thousand (9,600,000) shares, subject to adjustment upon changes in
capitalization of the Company as provided in Section 18 hereof. if, on a given Exercise Date, the number of shares with
respect to which options are to be exercised exceeds the number of shares then available under the plan, the Company
shall make a pro rata allocation of the shares remaining available for purchase in as uniform a manner as shall be
practicable and as it shall determine to be equitable. For the avoidance of doubt, up to the maximum number of shares
of Common Stock reserved under this Section 13 may be used to satisfy purchases of shares under the 423 Component
and any remaining portion of such maximum number of shares of Common Stock may be used to satisfy purchases of
shares under the non-423 Component.

6

such option has been exercised.

(b)

the participant shall have no interest or voting right in shares covered by his option until

(c)

Shares purchased by a participant under the plan shall be registered in the name of the 

participant (or, to the extent permitted under applicable law as determined by the administrator in its discretion, in the 
name of the participant and his or her spouse).

14. administration.

(a)

the plan shall be administered by the administrator. the administrator shall have full and

exclusive discretionary authority to adopt such rules, guidelines and forms as it deems appropriate to implement the plan,
to construe, interpret and apply the terms of the plan, to determine eligibility and to adjudicate all disputed claims filed
under the plan. Every finding, decision and determination made by the administrator shall, to the full extent permitted by
law, be final and binding upon all parties.

(b)

Without limitation to Section 14(a) above, the administrator will have the power, subject to, 

and within the limitations of, the express provisions of the plan to adopt such procedures and sub-plans as are necessary or 
appropriate to permit participation in the plan by Employees who are foreign nationals or employed outside the united 
States. Without limiting the generality of, and consistent with, the foregoing, the administrator specifically is authorized 
to adopt rules, procedures, and sub-plans regarding, without limitation, eligibility to participate in the plan and the 423 
Component or non-423 Component thereof, the definition of eligible “Compensation,” handling of payroll deductions, 
establishment of bank or trust accounts to hold payroll deductions, payment of interest, conversion of local currency, 
obligations to pay payroll tax, determination of beneficiary designation requirements, withholding procedures and 
handling of share issuances, any of which may vary according to applicable requirements, and which, if applicable to a 
Designated Subsidiary designated for participation in the non-423 Component, do not have to comply with the 
requirements of Section 423.

15. Designation of Beneficiary.

(a)

the Company may, but is not obligated to, permit a participant to file a written designation of
a beneficiary who is to receive any shares and cash, if any, from the participant’s account under the plan in the event of
such  participant’s  death  subsequent  to  an  Exercise  Date  on  which  the  option  is  exercised  but  prior  to  delivery  to  such
participant of such shares and cash, in a form or manner that is deemed to be acceptable to the Company. in addition, the
Company may, but is not obligated to, permit a participant to file a written designation of a beneficiary who is to receive
any  cash from  the  participant’s  account  under the  plan in  the  event  of  such participant’s  death  prior  to  exercise  of  the
option, in a form or manner that is deemed to be acceptable to the Company. if a participant is married and the designated
beneficiary is not the spouse, spousal consent shall be required for such designation to be effective.

changed by the participant by written notice in a form or manner that is deemed to be acceptable to the Company.

(b)

the Company may, but is not obligated to, permit such designation of beneficiary to be

(c)

in the event of the death of a participant and in the absence of a beneficiary validly designated

under the plan and applicable law (such validity being determined by the Company in its sole discretion) who is living at
the time of such participant’s death, the Company shall deliver such shares and/or cash to the executor or administrator of
the estate of the participant, or if no such executor or administrator has been appointed (to the knowledge of the
Company), the Company, in its discretion, may deliver such shares and/or cash to the spouse or to any one or more
dependents or relatives of the participant, or if no spouse, dependent or relative is known to the Company, then to such
other person as the Company may designate.

16. transferability. neither payroll deductions credited to a participant’s account nor any rights with regard to

the exercise of an option or to receive shares under the plan may be assigned, transferred, pledged or otherwise disposed of
in any way by the participant (other than by will, the applicable laws of descent and distribution or as may be provided
pursuant to Section 15 hereof). any such attempt at assignment, transfer,

7

pledge or other disposition shall be without effect, except that the Company may treat such act as an election to withdraw
funds from an offering period in accordance with Section 10 hereof.

17. use of Funds. Except as otherwise required by applicable law (as determined by the administrator in its

sole discretion), all payroll deductions received or held by the Company under the plan may be used by the Company for
any corporate purpose, and the Company shall not be obligated to segregate such payroll deductions.

18. adjustments upon Changes in Capitalization, Dissolution, liquidation, merger or asset Sale.

(a)

Changes in Capitalization. Subject to any required action by the stockholders of the Company,
the reserves, the maximum number of shares each participant may purchase each purchase period (pursuant to Section 7),
as well as the purchase price per share and the number of shares of Common Stock covered by each option under the plan
which has not yet been exercised shall be proportionately adjusted for any increase or decrease in the number of issued
shares of Common Stock resulting from a stock split, reverse stock split, stock dividend, combination or reclassification
of the Common Stock, or any other increase or decrease in the number of outstanding shares of Common Stock effected
without receipt of consideration by the Company; provided, however, that conversion of any convertible securities of the 
Company shall not be deemed to have been “effected without receipt of consideration”. Such adjustment shall be made by 
the administrator, whose determination in that respect shall be final, binding and conclusive. Except as expressly 
provided herein, no issuance by the Company of shares of stock of any class, or securities convertible into shares of stock 
of any class, shall affect, and no adjustment by reason thereof shall be made with respect to, the number or price of shares 
of Common Stock subject to an option.

(b)

Dissolution or liquidation. in the event of the proposed dissolution or liquidation of the

Company, the offering periods shall terminate immediately prior to the consummation of such proposed action, unless
otherwise provided by the administrator.

(c)

merger or asset Sale. in the event of a proposed sale of all or substantially all of the assets of

the Company, or the merger of the Company with or into another corporation, limited liability company or other entity,
the plan shall terminate upon the date of the consummation of such transaction and any purchase periods then in progress
shall be shortened by setting a new Exercise Date (the “new Exercise Date”) and any offering periods then in progress
shall end on the new Exercise Date, unless the plan of merger, consolidation or reorganization provides otherwise. the
new Exercise Date shall be determined by the administrator in its sole discretion; provided, that the new Exercise Date
shall be before the date of the Company’s proposed sale or merger. the administrator shall notify each participant in
writing, at least ten (10) business days prior to the new Exercise Date, that the Exercise Date for the participant’s option
has been changed to the new Exercise Date and that the participant’s option shall be exercised automatically on the new
Exercise Date, unless prior to such date the participant has withdrawn from the offering period as provided in Section 10
hereof. the plan shall in no event be construed to restrict the Company’s right to undertake any liquidation, dissolution,
merger, consolidation or other reorganization.

19. amendment or termination.

(a)

the Board (or any committee thereof to which it delegates such authority) may at any time

and for any reason terminate or amend the plan. Except as provided in Section 18 hereof, no such termination can affect
options previously granted, provided that an offering period may be terminated by the Board (or any committee thereof
to which it delegates such authority) on any Exercise Date if the Board (or such committee) determines that the
termination of such offering period is in the best interests of the Company and its stockholders. For purposes of the 423
Component, to the extent necessary to comply with Section 423 (or any successor rule or provision or any other
applicable law, regulation or stock exchange rule), the Company shall obtain stockholder approval in such a manner and
to such a degree as required.

(b)

Without stockholder consent and without regard to whether any participant rights may be

considered to have been “adversely affected,” the administrator shall be entitled to change the offering periods or
purchase periods, limit the frequency and/or number of changes in the amount withheld during an offering period,
establish the exchange ratio applicable to amounts withheld in a currency other than u.S. dollars,

8

permit payroll withholding in excess of the amount designated by a participant in order to adjust for delays or mistakes in
the Company’s processing of properly completed withholding elections, establish reasonable waiting and adjustment
periods and/or accounting and crediting procedures to ensure that amounts applied toward the purchase of Common Stock
for each participant properly correspond with amounts withheld from the participant’s Compensation, and establish such
other limitations or procedures as the administrator determines in its sole discretion advisable which are consistent with
the plan.

20. notices. all notices or other communications by a participant to the Company under or in connection with
the plan shall be deemed to have been duly given when received in the form specified by the Company at the location, or
by the person, designated by the Company for the receipt thereof.

21. Conditions upon issuance of Shares. Shares shall not be issued with respect to an option unless the exercise
of such option and the issuance and delivery of such shares pursuant thereto shall comply with all applicable provisions of
law, domestic or foreign, including, without limitation, the u.S. Securities act of 1933, as amended, the u.S. Securities
Exchange act of 1934, as amended, the rules and regulations promulgated thereunder, and the requirements of any stock
exchange or stock market upon which the shares may then be listed, and any other applicable securities, exchange control
or other regulations, and shall be further subject to the approval of counsel for the Company with respect to such
compliance.

as a condition to the exercise of an option, the Company may require the person exercising such option

to represent and warrant at the time of any such exercise that the shares are being purchased only for investment and
without any present intention to sell or distribute such shares if, in the opinion of counsel for the Company, such a
representation is required by any of the aforementioned applicable provisions of law.

22. no rights as an Employee. nothing in the plan or in any right granted under the plan shall confer upon a

participant any right to continue in the employ of the Company or any Designated Subsidiary for any period of specific
duration or interfere with or otherwise restrict in any way the rights of the Company or any Designated Subsidiary or of a
participant, which rights are hereby expressly reserved by each, to terminate his or her employment at any time and for
any reason, with or without cause (subject to applicable law).

23. term of plan. the plan, as amended and restated, shall become effective upon the Effective Date. it shall 

continue until terminated under Section 19 hereof.

24. automatic transfer to low price offering period. to the extent permitted by any applicable laws,
regulations, or stock exchange rules, if the Fair market value of the Common Stock on any Exercise Date in an offering
period is lower than the Fair market value of the Common Stock on the Enrollment Date of such offering period, then all
participants in such offering period shall be automatically withdrawn from such offering period immediately after the
exercise of their option on such Exercise Date and automatically re-enrolled in the immediately following offering period
as of the first day thereof.
