Item 1.   Business

Overview

PART I

We  are  a  commercial-stage  biopharmaceutical  company  with  a  mission  to  increase  patient  access  to  cost-effective
medicines  that  can  have  a  major  impact  on  their  lives  and  to  deliver  significant  savings  to  the  health  care  system.  Our  first
product,  UDENYCA®  (pegfilgrastim-cbqv),  a  biosimilar  to  Neulasta®,  a  long-acting  granulocyte-colony  stimulating  factor,  was
launched  commercially  in  the  United  States  in  January  2019.  Biosimilars  are  a  class  of  protein-based  therapeutics  with  high
similarity to approved originator products on the basis of various structural and biologic properties, as well as in terms of safety
and efficacy. We have become a leader in the biosimilar market by leveraging our team’s collective expertise in key areas such
as  process  science,  analytical  characterization,  protein  production,  clinical-regulatory  development  and  commercialization.  In
addition to UDENYCA®, we have a product candidate pipeline that includes biosimilars of Humira®, Avastin® and Lucentis®.

We are investing cash flows generated by our commercial biosimilars business to build a leading immuno-oncology

franchise in the United States and Canada. In February 2021, we in-licensed Junshi Biosciences’ toripalimab, a novel anti-PD-1
antibody, which was first approved in 2018 for second-line treatment of melanoma in China, where it is marketed by Shanghai
Junshi Biosciences, Co., Ltd. (“Junshi Biosciences”). Toripalimab has been extensively evaluated in late-stage clinical trials for
the treatment of multiple tumor types. We and Junshi Biosciences expect to submit the first biologic license application (“BLA”) to
the United States Food and Drug Administration (“FDA”) in 2021 for the treatment of third-line nasopharyngeal carcinoma, an
indication for which the FDA has granted toripalimab Breakthrough Therapy designation. Within the next several years, we and
Junshi Biosciences anticipate submitting BLAs for multiple additional indications for rare and highly prevalent tumor types,
including non-small cell lung cancer. We have also acquired options to license two pipeline immuno-oncology product
candidates from Junshi Biosciences, an anti-TIGIT antibody and a next-generation engineered IL-2 cytokine, which we plan to
evaluate in combination with toripalimab.

With our UDENCYA commercialization efforts, we have built a strong, oncology-focused commercial capability in the

United States. We expect to leverage this commercial capability as we build our immuno-oncology franchise if we are successful
with the development and registration of toripalimab and potential combination product candidates.

Our pipeline includes the following product candidates:

Oncology Pipeline

●

Toripalimab, an anti-PD-1 antibody being developed in collaboration with Junshi Biosciences, a leading Chinese
biotechnology company. So far, more than thirty company-sponsored clinical studies covering more than fifteen
indications have been conducted globally, including in China and the United States, on toripalimab. On December
17, 2018, toripalimab obtained a conditional approval from the National Medical Products Administration of China
(“NMPA”) for the second-line treatment of patients with unresectable or metastatic melanoma, making it the first
Chinese domestic anti-PD-1 monoclonal antibody to obtain marketing approval in China. Supplemental new drug
applications (“NDAs”) of toripalimab for the third-line treatment of recurrent/metastatic nasopharyngeal carcinoma
and second-line treatment of metastatic urothelial carcinoma were accepted by the NMPA in April and May 2020,
respectively. Both supplemental NDAs received priority review designations from the NMPA in July 2020. In
December 2020, toripalimab was included in the National Reimbursement Drug List (“NRDL”) for the treatment of
melanoma by the China National Healthcare Security Administration (“NHSA”).

In the United States, toripalimab was granted the Breakthrough Therapy designation for the treatment of
recurrent/metastatic nasopharyngeal carcinoma by the FDA in September 2020. The FDA has also granted
toripalimab Fast Track designation for the treatment of mucosal melanoma and orphan drug designations for
treatment of nasopharyngeal carcinoma, mucosal melanoma and soft tissue sarcoma.

We expect the first toripalimab Biologics License Application (“BLA”) to be submitted to the FDA for
recurrent/metastatic nasopharyngeal carcinoma in 2021. In addition to nasopharyngeal carcinoma, we and Junshi
Biosciences plan to submit BLAs

to the FDA for toripalimab within the next two years for the treatment of several rare and highly prevalent cancers,
including non-small cell lung cancer.

UDENYCA® (pegfilgrastim-cbqv). We are continuing to develop additional presentations of UDENYCA®.

Bevacizumab  (Avastin)  biosimilar  and  option  to  license  rituximab  (Rituxan®)  biosimilar.  On  January  13,  2020,  we
entered  into  a  license  agreement  with  Innovent  Biologics  (Suzhou)  Co.,  Ltd.  (“Innovent,”  and  with  respect  to  the
license  agreement  with  Innovent,  the  “Innovent  Agreement”)  for  the  development  and  commercialization  of  a
biosimilar version of bevacizumab (Avastin) in any dosage form and presentations (“bevacizumab Licensed Product”)
in the United States and Canada. Under the Innovent Agreement, Innovent granted us an exclusive, royalty-bearing
license  to  develop  and  commercialize  the  bevacizumab  Licensed  Product  in  the  field  of  treatment,  which  is  the
prevention  or  amelioration  of  any  human  diseases  and  conditions  as  included  in  the  label  of  Avastin.  We  also
acquired  an  option  for  twelve  months  to  develop  and  commercialize  Innovent’s  biosimilar  version  of  rituximab
(Rituxan®) in any dosage form and presentations in the United States and Canada.

We  are  performing  a  three-way  pharmacokinetic  (“PK”)  study  using  Avastin  drug  products  from  the  United  States,
Avastin  drug  products  from  China  and  Innovent’s  biosimilar  to  bevacizumab,  as  well  additional  analytical  similarity
exercises prior to submitting a BLA for a biosimilar product candidate, or a 351(k) BLA, to the FDA.

Immunology Pipeline

CHS-1420  (our  adalimumab  (Humira)  biosimilar  candidate).  We  are  developing  CHS-1420,  an  anti-TNF  product
candidate,  as  an  adalimumab  (Humira)  biosimilar.  In  August  2016,  we  announced  positive  data  from  our  Phase  3
study in psoriasis patients, followed by confirmatory 24-week results in January 2017. In the fourth quarter of 2020,
we submitted the 351(k) BLA, which was accepted for review by the FDA in February 2021. The user fee goal date is
in December 2021. If approved, we anticipate we would be able to launch CHS-1420 in the United States on or after
July 1, 2023, in accordance with settlement and license agreements with AbbVie Inc. (“AbbVie”) that grants us global,
non-exclusive license rights under AbbVie’s intellectual property to commercialize CHS-1420.

Ophthalmology Pipeline

Ranibizumab  (Lucentis)  Biosimilar.  On  November  4,  2019,  we  entered  into  a  license  agreement  with  Bioeq  IP  AG
(now  Bioeq  AG  or  “Bioeq”)  for  the  commercialization  of  a  biosimilar  version  of  ranibizumab  (Lucentis)  in  certain
dosage  forms  in  both  a  vial  and  pre-filled  syringe  presentation.  Under  this  agreement,  Bioeq  granted  to  us  an
exclusive  royalty-bearing  license  to  commercialize  Bioeq’s  biosimilar  to  ranibizumab  in  the  field  of  ophthalmology
(and any other approved labelled indication) in the United States.

The Bioeq ranibizumab biosimilar candidate demonstrated similar binding and bioactivity as Lucentis (ranibizumab)
and met its primary endpoint in a wet age-related macular degeneration (“wet AMD”) Phase 3 study. At the request of
a national European health authority addressed to Bioeq’s drug substance contract manufacturer, the manufacturer
moved a piece of processing equipment to a different location within the same site after the production of the Bioeq
ranibizumab biosimilar candidate qualification batches was completed. The FDA requested additional manufacturing
data for the equipment in its new location in the context of its review of the 351(k) BLA. As a result, Bioeq decided to
withdraw  its  351(k)  BLA  for  this  candidate  and  provide  the  requested  data.  During  the  first  quarter  of  2021,  Bioeq
received positive pre-BLA filing feedback from the FDA on the requested manufacturing data, and the FDA indicated
support of Bioeq’s current plans to proceed with the resubmission of its 351(k) BLA during 2021.  

Small Molecule Pipeline

●

CHS-131 (our oral, small-molecule drug candidate). CHS-131 is a novel, potential first-in-class, once-daily oral drug
candidate  for  non-alcoholic  steatohepatitis  (“NASH”)  and  other  metabolic  conditions.  In  February  2020,  we
announced that we are seeking strategic alternatives to finance this program externally.

Market Opportunity for Biosimilars

According to Evaluate Pharma, total U.S. annual revenues of Neulasta, Avastin, Lucentis and Humira, which are the

reference drugs of our commercialized or late stage biosimilar candidates of pegfilgrastim, bevacizumab, ranibizumab, and
adalimumab, respectively, and other commercial biosimilar drugs for those compounds are expected to reach approximately
$22.0 billion in 2020. We intend to pursue a branded biosimilar strategy to address this potential commercial opportunity,
emphasizing a high level of similarity of our biosimilar products to the originators, while offering significantly more value to the
U.S. healthcare system.

The  global  market  opportunity  for  biosimilars  is  large  and  growing  because  of  several  factors.  First,  many  of  the  top-
grossing biologic drugs in the world faced, or are facing the expiry of their patent protection. Second, regulatory agencies around
the  world  have  responded  to  these  upcoming  patent  expirations  by  establishing  biosimilar  approval  pathways.  We  believe
regulatory agencies will help streamline the approval process across various international regulatory agencies and encourage
growth  of  the  overall  biosimilar  market.  Third,  implementation  of  more  stringent  cost  containment  practices  on  the  part  of
governments and insurers has increased demand for high-quality biosimilars, which we believe will result in substantial market
growth over time. Further, in the U.S., the largest market for biologics, we believe that government policy mandating healthcare
insurance coverage of treatments for pre-existing conditions will continue for the foreseeable future and will increase demand for
high-quality biosimilars.

While  the  potential  market  opportunity  is  significant,  biosimilar  product  development  poses  a  number  of  scientific,
regulatory and technical challenges that distinguish it from traditional, small-molecule generic product development. We believe
our  world-class  team  of  biologic  therapeutic  developers  and  renowned  scientists  gives  us  the  critical  capabilities  to  address
successfully the complexities underlying these challenges. We have also assembled a distinguished scientific advisory board of
leading scientists who are acknowledged experts in their respective fields. With the approval and successful commercial launch
of  UDENYCA®,  we  believe  we  have  demonstrated  our  core  capabilities  and  expertise  in  product  development  in  the  United
States and EU, and commercialization in the United States.

Our business model places our internal team at the center of a coordinated development effort in which our senior team
of experts focuses on the highly specialized, strategic and technical aspects of biosimilar development. For other aspects of our
operations that require greater scale or more capital-intensive investments, we have established a network of relationships with
highly competent external organizations and strategic partnerships that we believe will provide the competitive scale required to
address  the  global  biosimilar  market  opportunity.  For  example,  in  December  2015,  we  entered  into  a  strategic  manufacturing
agreement with KBI Biopharma, Inc. (“KBI Biopharma”), based in Boulder, Colorado, for long-term commercial manufacturing of
UDENYCA®.  In  November  2018,  we  extended  our  partnership  with  KBI  until  December  31,  2023.  In  addition,  our  dynamic
organization allows us to respond to the rapidly evolving biosimilar landscape. We also seek to become a partner of choice to
maximize  the  U.S.  commercial  biosimilar  opportunity,  as  exemplified  by  our  recent  licensing  agreements  with  Bioeq  and
Innovent.

Oncology Franchise Opportunity

UDENYCA® (pegfilgrastim-cbqv)

UDENYCA®  (pegfilgrastim-cbqv)  is  a  biosimilar  to  Neulasta,  a  long-acting  granulocyte  stimulating  colony  factor.  The
production of granulocytes (a type of white blood cell, which includes leukocytes) promotes the body’s ability to fight infections.
UDENYCA® is a leukocyte growth factor indicated to decrease the incidence of infection, as manifested by febrile neutropenia,
in patients with non-myeloid malignancies receiving myelosuppressive anti-cancer drugs associated with a clinically significant
incidence of febrile neutropenia.

We  initiated  U.S.  sales  of  UDENYCA®  in  January  2019.  According  to  Evaluate  Pharma,  the  2020  U.S.  sales  for  all

pegfilgrastim products represent an estimated $2.6 billion.

Bevacizumab (Avastin) Biosimilar Opportunity

Avastin is a recombinant humanized monoclonal antibody that selectively binds circulating VEGF, thereby inhibiting the
binding of VEGF to its cell surface receptors. This inhibition leads to a reduction in microvascular growth of tumor blood vessels
and thus limits the blood supply to various types of tumor tissues. Avastin was first approved in 2004 by the FDA for combination
use  with  standard  chemotherapy  for  metastatic  colon  cancer  for  the  treatment  of  metastatic  colorectal  cancer,  non-small  cell
lung cancer, metastatic kidney cancer, advanced cervical cancer, platinum-resistant ovarian cancer and recurrent glioblastoma.

Table of Contents

Evaluate  Pharma  estimated  that  the  2020  U.S.  sales  for  Avastin  were  $1.9  billion.  In  January  2020,  we  acquired  the

right to commercialize Innovent’s Avastin biosimilar candidate in the United States and Canada.

Toripalimab Opportunity

In  February  2021,  we  acquired  exclusive  rights  in  the  United  States  and  Canada  for  the  co-development  and
commercialization of Junshi Biosciences’ toripalimab. Toripalimab is a humanized IgG4 anti-PD-1 monoclonal antibody selected
for  its  potential  to  block  PD-1  interactions  with  its  ligands,  PD-(L)1  and  PD-(L)2,  and  for  its  potential  to  provide  enhanced
receptor endocytosis function. PD-(L)1 and PD-(L)2 are tumor checkpoint proteins that recognize the PD-1 receptor on T cells
and exhaust their anti-tumor activity. Blocking PD-1 interactions with PD-(L)1 and PD-(L)2 allows T cells to attack and kill tumor
cells that display PD-(L)1 or PD-(L)2.

According to Evaluate Pharma, total anti-PD-1 antibody U.S. annual revenues in 2020 were approximately $15.0 billion
and are projected to grow to approximately $30.0 billion by 2026. Non-small cell lung cancer accounted for approximately 50%
of all anti-PD-1 antibody U.S. revenues in 2020 and is expected to remain the largest tumor segment in the foreseeable future.

Ophthalmology Franchise Opportunity

Ranibizumab (Lucentis) Biosimilar Candidate

Lucentis is a monoclonal antibody fragment (“Fab”) created from the same parent mouse antibody as bevacizumab and
produced  through  a  microbial  culture.  It  blocks  angiogenesis  by  inhibiting  vascular  endothelial  growth  factor  A.  Lucentis  is
approved in the United States for indications including wet AMD, macular edema following retinal vein occlusion, and diabetic
retinopathy.

According to Evaluate Pharma, Lucentis achieved approximately $1.5 billion in U.S. sales in 2020. In November 2019,

we in-licensed U.S. commercial rights to Bioeq’s ranibizumab (Lucentis) biosimilar.

Immunology Franchise Opportunity

Our  biosimilar  candidate,  CHS-1420  (adalimumab  (Humira)  biosimilar)  binds  to  tumor  necrosis  factor  (“TNF”),  which
belongs to a family of soluble protein mediators (“cytokines”) that play an important role in disease progression across a number
of inflammatory and chronic conditions, including rheumatoid arthritis, psoriatic arthritis, ankylosing spondylitis, Crohn’s disease,
psoriasis  and  ulcerative  colitis.  Cytokines,  such  as  TNF,  are  substances  produced  by  cells  in  the  body  that  can  cause  a
biological effect on other cells in the body. TNF is generally understood as the “master regulator” of the body’s immune response
and is the key initiator of immune-mediated inflammation in multiple organ systems.

CHS-1420 (Our Adalimumab (Humira) Biosimilar Candidate)

Humira, which is the reference product for CHS-1420, is a monoclonal antibody that can bind to TNF, thereby inhibiting
the known effect of this substance as a potent mediator of inflammation. Humira thus provides a therapeutic benefit for treatment
of various inflammatory diseases characterized by increased production of TNF in the body.

Evaluate Pharma estimated that 2020 U.S. sales of Humira reached approximately $16.0 billion in 2020. Our settlement
and  license  agreements  with  AbbVie  grant  us  global,  non-exclusive  worldwide  rights  under  AbbVie’s  intellectual  property  to
manufacture  and  commercialize  CHS-1420  starting  on  July  1,  2023.  We  believe  that  a  targeted  commercial  strategy  against
certain anti-TNF segments may enable us to achieve substantial topline sales for CHS-1420 in the United States, if approved.

Deprioritized pipeline programs

In February 2020, we announced that we would seek strategic alternatives for CHS-131, a PPARγ small molecule being

evaluated for the treatment of NASH.

Table of Contents

In February 2021, we announced discontinuation of the development of CHS-2020, a biosimilar of Eylea® as part of a

realignment of research and development resources toward the development of immuno-oncology assets including toripalimab.

Sales and Marketing

Our  strategy  is  to  invest  cash  flows  from  our  commercial  biosimilars  business  to  build  a  leading  immuno-oncology

franchise in the United States and Canada.

The sales call points to oncologists in the United States are highly concentrated and addressable by our relatively small
commercial  organization.  If  we  are  successful  in  gaining  approval  of  our  bevacizumab  biosimilar  or  of  toripalimab  and  other
immuno-oncology assets, we will plan to commercialize these products alongside UDENYCA through our oncology sales and
marketing  team.  Similarly,  for  our  ophthalmology  franchise,  we  anticipate  that  the  number  of  accounts  to  drive  90%  of  sales
volume is approximately four- to five-fold smaller than that for the oncology support of care market. As a result, we anticipate a
relatively small incremental investment in additional sales force will be needed to address the ophthalmology marketplace. For a
discussion of risks related to sales and marketing, please see “Risk Factors—Risks Related to Launch and Commercialization of
UDENYCA® and our Other Product Candidates.”

Manufacturing

We have entered into agreements with several contract manufacturing organizations (“CMOs”) for the manufacture and
clinical drug supply of our commercial and products candidates. We continue to screen other contract manufacturers to meet our
clinical, commercial and regulatory supply requirements on a product-by-product basis. For a discussion of risks related to our
sources and availability of supplies, please see “Risk Factors—Risks Related to Our Ability to Hire and Retain Highly Qualified
Personnel and Risks Related to Manufacturing and Supply Chain.”

Competition

The development and commercialization of protein-based therapeutics is highly competitive. While we believe that our
biologics  platform,  knowledge,  experience  and  scientific  resources  provide  us  with  competitive  advantages,  we  face  potential
competition  from  many  different  sources.  Such  competition  includes  larger  and  better-funded  pharmaceutical,  generic
pharmaceutical,  specialty  pharmaceutical  and  biotechnology  companies,  as  well  as  originator  companies  and  any  other  firms
developing the biosimilars that would compete with the product candidates in our pipeline and other novel products with similar
indications.

UDENYCA® (pegfilgrastim-cbqv) faces competition in the United States from Amgen (“Amgen”), Viatris Inc. (“Viatris”),
Mylan N.V. (“Mylan”), Sandoz International GmbH (“Sandoz”), Pfizer Inc., and may face competition from Amneal and Fresenius,
each of which has announced the development of a pegfilgrastim biosimilar.

Toripalimab, if approved, will enter a competitive market in the United States where a number of anti-PD-1 or PD-(L)1
antibody  drugs  have  been  approved  by  the  FDA  including  the  following  marketed  products  from  several  competitors:
Keytruda® (pembrolizumab) from Merck & Company, Inc. (“Merck”), Opdivo® (nivolumab) from Bristol-Myers Squibb Company
(“BMS”),  Tecentriq®  (atezolizumab)  from  Genentech  USA,  Inc.  (“Genentech”),  Imfinzi®  (durvalumab)  from  AstraZeneca,
Bavencio®  (avelumab)  from  EMD  Serono  and  Pfizer,  and  Libtayo®  (cemiplimab-rwlc)  from  Regeneron  Pharmaceuticals,  Inc.
(“Regeneron”) and Sanofi. In addition to toripalimab, multiple other competitors are seeking to develop and approve novel anti-
PD-1  or  PD-(L)1  antibody  drugs  in  the  United  States  in  the  coming  years,  including  but  not  limited  to  BeiGene,  Ltd.  (in
collaboration with Novartis), GlaxoSmithKline PLC and Innovent.

Innovent’s  bevacizumab  (Avastin)  may  face  competition  in  the  United  States  from  Genentech,  Inc.  (“Genentech,”  the
holder of rights to Avastin), as well as Amgen (MvasiTM (bevacizumab-awwb)) and Pfizer (ZirabevTM (bevacizumab-bvzr)), each
of  which  have  initiated  the  commercial  launch  of  an  Avastin  biosimilar.  We  may  also  face  competition  from  several  other
companies with Avastin biosimilar candidates in development or in registration, including Samsung Bioepis Co., Ltd. (Samsung
Bioepis”) and Viatris.

Bioeq’s  ranibizumab  (Lucentis)  biosimilar  candidate  may  face  competition  in  the  United  States  from  Genentech  (the
manufacturer of Lucentis). Biogen Inc. (“Biogen”) with collaborator Samsung Bioepis Co., Ltd. (Samsung Bioepis), and Xbrane
Biopharma AB (in collaboration with STADA Arzneimittel AG and Bausch + Lomb) have each disclosed the development of a
Lucentis biosimilar candidate.

CHS-1420, our adalimumab (Humira) biosimilar candidate, may face competition in the U.S. from AbbVie (the holder of
rights  to  Humira),  Amgen  (AmjevitaTM  (adalimumab-atto)),  Sandoz  (HyrimozTM  (adalimumab-adaz)),  Samsung  Bioepis
(HadlimaTM (adalimumab-bwwb)), Pfizer (AbriladaTM (adalimumab-afzd)), Boehringer Ingelheim GmbH (“Boehringer Ingelheim”)
(CyltezoTM (adalimumab-adbm)) as well as Fujifilm, Alvotech and Fresenius, companies that have each disclosed development
plans for a Humira biosimilar candidate.

We expect any products that we develop and commercialize directly or with partners to compete on the basis of, among
other  things,  price  and  the  availability  of  reimbursement  from  government  and  other  third-party  payers.  Our  competitors  also
may obtain FDA or other regulatory approval for their products more rapidly than we may obtain approval for ours, which could
result in our competitors establishing a strong market position before we are able to enter the market. For a discussion of risks
related to our competition, please see “Risk Factors — Risks Related to Competitive Activity.”

Collaboration and License Agreements

Distribution Agreement with Orox Pharmaceuticals B.V.

In  December  2012,  we  entered  into  a  distribution  agreement  with  Orox  Pharmaceuticals  B.V.  (“Orox”),  for  the
commercialization of biosimilar versions of our internally developed biosimilars. Under this agreement, we granted to Orox an
exclusive license to commercialize UDENYCA® in Latin America, except Brazil and Argentina, and CHS-1420 and CHS-0214
(our etanercept (Enbrel®) biosimilar candidate, which we discontinued development) in Latin America, except Brazil. Under this
agreement, Orox has an option, exercisable within a defined time period, to obtain an exclusive license to commercialize certain
additional biosimilar products in the same field and territory. We are obligated to manufacture and supply licensed products to
Orox.

We  are  obligated  to  develop  licensed  products  and  achieve  regulatory  approval  for  such  products  outside  of  the
Caribbean and Latin American countries covered by the agreement by specified dates in order to support Orox’s activities under
the  agreement  in  its  licensed  territory.  We  are  eligible  to  receive  from  Orox  a  share  of  gross  profits  in  the  low  twenty  percent
range from the sale of licensed products, on a product-by-product basis.

Our  agreement  with  Orox  will  expire  on  a  product-by-product  and  country-by-country  basis  ten  years  after  regulatory
approval of such product in such country, subject to automatic three-year extensions unless Orox notifies us in writing at least
18 months in advance of the date upon which the term would otherwise expire that it does not wish to extend the term for such
product in such country. Either party may terminate the agreement for material breach by the other party that is not cured within
a specified time period. Orox may terminate the Agreement for convenience on a product-by-product basis at any time upon 12-
months prior written notice. Each party may terminate the agreement upon bankruptcy or insolvency of the other party, and we
may  terminate  the  agreement  immediately  upon  written  notice  to  Orox  if  Orox  challenges  the  licensed  patents  or  commits  a
breach of specified provisions of the agreement.

License Agreements with Selexis SA

In  April  2011  and  June  2012,  we  entered  into  license  agreements  with  Selexis  SA  (“Selexis”),  under  which  Selexis
granted to us royalty-bearing, non-exclusive, sublicensable licenses under Selexis’s intellectual property rights to manufacture,
use and commercialize two of our biosimilar products using Selexis cell lines. In consideration for the rights granted to us under
the agreements, we made cash upfront payments to Selexis and are required to make payments based upon the achievement
of certain development, regulatory and commercial milestones for such biosimilar products, totaling up to €210,000 for each of
the two products, or a total aggregate amount of €420,000. In addition, we are also required to pay a royalty as a percentage of
revenue on a product-by-product and country-by-country basis in the low-single digits.

We  may  terminate  each  agreement  at  any  time  upon  60  days  written  notice  to  Selexis.  Either  we  or  Selexis  may
terminate an agreement for any material breach by the other party that is not cured within a specified time period or in the event
of the other party’s insolvency. Absent earlier termination, the agreements with Selexis terminate on a country-by-country and
product-by-product basis on the expiration of the last-to-expire or lapse of the valid patent claims covering such product in such
country.

Settlement and License Agreements with AbbVie, Inc.

On January 24, 2019, we entered into three settlement and license agreements with AbbVie that grant Coherus global,
royalty-bearing,  non-exclusive  license  rights  under  AbbVie’s  intellectual  property  to  commercialize  CHS-1420,  our  proposed
adalimumab (Humira)

biosimilar. The global settlements resolve all pending disputes between the parties related to our adalimumab biosimilar. Under
the U.S. settlement, our license period in the U.S. commences on July 1, 2023.

Settlement and License Agreements with Pfizer, Inc.

In  October  2019,  we  entered  into  a  license  and  settlement  agreement  with  Pfizer  relating  to  Coherus’  patents  and

applications for patents directed to Humira (adalimumab) formulations.

License Agreement with Bioeq AG

On November 4, 2019, we entered into a license agreement with Bioeq for the commercialization of a biosimilar version
of  ranibizumab  (Lucentis)  in  certain  dosage  forms  in  both  a  vial  and  pre-filled  syringe  presentation  (the  “Bioeq  Licensed
Products”).  Under  this  agreement,  Bioeq  granted  to  us  an  exclusive,  royalty-bearing  license  to  commercialize  the  Bioeq
Licensed  Products  in  the  field  of  ophthalmology  (and  any  other  approved  labelled  indication)  in  the  United  States.  Bioeq  will
supply  to  us  the  Bioeq  Licensed  Products  in  accordance  with  terms  and  conditions  specified  in  the  agreement  and  a
manufacturing and supply agreement to be executed by the parties in accordance therewith.

Under the Bioeq Agreement, Bioeq must use commercially reasonable efforts to develop and obtain regulatory approval
of the Bioeq Licensed Products in the United States in accordance with a development and manufacturing plan, and we must
use  commercially  reasonable  efforts  to  commercialize  the  Bioeq  Licensed  Products  in  accordance  with  a  commercialization
plan. Additionally, we must commit certain pre-launch and post-launch resources to the commercialization of the Bioeq Licensed
Products for a limited time as specified in the agreement. The development, manufacturing, and commercialization of the Bioeq
Licensed Products in the United States is governed by a governance committee as described in more detail in the agreement.

We paid Bioeq an upfront payment of €5.0 million and a milestone payment of €5.0 million. Additionally, we are obligated
to  pay  Bioeq  in  the  future  an  aggregate  of  up  to  €25.0  million  in  milestone  payments  in  connection  with  the  achievement  of
certain development and regulatory milestones with respect to the Bioeq Licensed Products in the United States. We will share
a percentage of gross profits on sales of Bioeq Licensed Products in the United States with Bioeq in the low to mid fifty percent
range.

The Bioeq Agreement’s initial term continues in effect for ten years after the first commercial sale of a Bioeq Licensed
Product in the United States, and thereafter renews for an unlimited period of time unless otherwise terminated in accordance
with its terms. Either party may terminate the Bioeq Agreement for the other party’s material breach which is not cured within a
specified time period or for the other party’s bankruptcy or insolvency-related events. Bioeq may terminate the Bioeq Agreement
in  certain  limited  circumstances  for  failure  to  obtain  specified  minimum  market  share  requirements  during  certain  windows  of
time, if we conduct certain commercial or advanced pre-commercial activities with respect to certain competitive products, if we
challenge the validity or enforceability of the patent rights licensed to us under the Bioeq Agreement, or if we undergo a change
of control with a competitor of Bioeq and do not divest certain competitive products in connection therewith. We may terminate
the Bioeq Agreement for convenience with 18 months advance written notice (provided that such termination shall not become
effective prior to 12 months after the first commercial sale of the first Bioeq Licensed Product in the United States). We may also
terminate  the  Bioeq  Agreement  in  certain  circumstances  of  delays,  or  anticipated  delays,  in  the  achievement  of  regulatory
approval of the first Bioeq Licensed Product in the United States, or if Bioeq receives certain adverse regulatory feedback from
the FDA for the Bioeq Licensed Products.

The Bioeq ranibizumab biosimilar candidate demonstrated similar binding and bioactivity as ranibizumab (Lucentis) and
met  its  primary  endpoint  in  a  wet  AMD  Phase  3  study.  At  the  request  of  a  national  European  health  authority  addressed  to
Bioeq’s drug substance contract manufacturer, the manufacturer moved a piece of processing equipment to a different location
within the same site after the production of the Bioeq ranibizumab biosimilar candidate qualification batches was completed. In
February  2020,  the  FDA  requested  additional  manufacturing  data  for  the  equipment  in  its  new  location  in  the  context  of  its
review of the 351(k) BLA, and Bioeq withdrew its BLA. During the first quarter of 2021, Bioeq received positive pre-BLA filing
feedback from the FDA on the requested manufacturing data, and the FDA indicated it was supportive of Bioeq’s current plans
to proceed with the resubmission of its 351(k) BLA during 2021.

License Agreement with Innovent Biologics (Suzhou) Co., Ltd.

On  January  13,  2020,  we  entered  into  a  license  agreement  with  Innovent  (the  “Innovent  Agreement”)  for  the
development and commercialization of a biosimilar version of bevacizumab (Avastin) in any dosage form and presentations (the
“bevacizumab Licensed

8

Table of Contents

Product”) in the United States and Canada (the “Territory”). Under the Innovent Agreement, Innovent granted us an exclusive,
royalty-bearing license to develop and commercialize the bevacizumab Licensed Product in the field of treatment, prevention or
amelioration  of  any  human  diseases  and  conditions  as  included  in  the  label  of  Avastin.  We  also  acquired  an  option  for
twelve  months  to  develop  and  commercialize  Innovent’s  biosimilar  version  of  rituximab  (Rituxan®)  in  any  dosage  form  and
presentations (the “rituximab Licensed Product” and together with the bevacizumab Licensed Product, the “Innovent Licensed
Products”)  in  the  Territory.  Subject  to  the  terms  of  the  Innovent  Agreement,  we  may  exercise  our  option  within  12  months  of
receiving  certain  regulatory  materials  from  Innovent.  Following  our  option  exercise,  Innovent’s  biosimilar  version  of  rituximab
would be deemed an Innovent Licensed Product and Innovent would grant us an exclusive, royalty-bearing license to develop
and commercialize Innovent’s biosimilar version of rituximab in the field of treatment, prevention or amelioration of any human
diseases and conditions as included in the label of Rituxan®.

Innovent will supply the Innovent Licensed Products to us in accordance with a manufacturing and supply agreement to
be  executed  by  the  parties.  Under  the  Innovent  Agreement,  we  acquired  the  right  to  require  Innovent  to  perform  technology
transfer  for  the  manufacturing  of  the  Innovent  Licensed  Products  in  the  Territory  and,  upon  completion  of  such  technology
transfer, we will have the exclusive right to manufacture the Innovent Licensed Products in the Territory.

We  paid  Innovent  an  upfront  payment  of  $5.0  million  and  a  milestone  payment  of  $2.5  million.  Additionally,  we  are
obligated  to  pay  Innovent  an  aggregate  of  up  to  $37.5  million  in  milestone  payments  in  connection  with  the  achievement  of
certain development, regulatory and sales milestones with respect to the bevacizumab Licensed Product and, if we exercise our
option to license Innovent’s rituximab biosimilar, an aggregate of up to $40.0 million in milestone payments in connection with
the achievement of certain development, regulatory and sales milestones with respect to the rituximab Licensed Product. We will
share a percentage of net sales of Innovent Licensed Products with Innovent in the mid-teens to low twenty percent range. If we
exercise  our  option,  we  would  be  required  to  pay  an  option  exercise  fee  of  $5.0  million.  Subject  to  the  terms  of  the  Innovent
Agreement, if we request Innovent to perform technology transfer for the manufacturing of the Innovent Licensed Products, we
would be required to pay up to $10.0 million for fees related thereto.

For  the  bevacizumab  Licensed  Product,  the  initial  term  continues  in  effect  for  ten  years  after  the  effective  date  of  the
Innovent  Agreement,  and  thereafter  renews  for  successive  two-year  periods  upon  mutual  agreement  by  the  parties,  unless
otherwise terminated in accordance with its terms. For the rituximab Licensed Product, the initial term would continue in effect
for  ten  years  after  the  effective  date  of  the  option  effective  date  and  thereafter  would  renew  for  successive  two-year  periods
upon mutual agreement by the parties, unless otherwise terminated in accordance with its terms. Either party may terminate the
Innovent Agreement for the other party’s material breach that is not cured within a specified time period or for the other party’s
bankruptcy or insolvency-related events. Innovent may terminate the Innovent Agreement if we undergo a change of control with
a  competitor  of  Innovent  and  does  not  assign  the  Innovent  Agreement  to  a  third  party  within  a  certain  period  of  time.  On  an
Innovent  Licensed  Product-by-Licensed  Product  basis,  we  may  terminate  the  Innovent  Agreement  based  on  certain  market
conditions  beginning  12  months  after  the  first  commercial  sale  of  such  Innovent  Licensed  Product  with  18  months  advance
written notice. Also on an Innovent Licensed Product-by-Licensed Product basis, we may terminate the Innovent Agreement in
certain  circumstances  of  delays,  or  anticipated  delays,  in  the  achievement  of  regulatory  approval  of  such  Innovent  Licensed
Product  in  the  United  States,  if  we  receive  certain  adverse  regulatory  feedback  from  the  FDA  for  such  Innovent  Licensed
Product, or if we receive written FDA meeting minutes indicating that the FDA recommends an additional Phase 3 clinical trial
efficacy  comparability  study  to  support  the  regulatory  approval  of  such  Innovent  Licensed  Product  in  the  United  States.  The
bevacizumab  Licensed  Product  demonstrated  PK  bioequivalence  and  showed  equivalent  clinical  efficacy  to  Avastin
(bevacizumab) in a non-small cell lung carcinoma Phase 3 study.

License Agreement with Junshi Biosciences

On  February  1,  2021,  we  entered  into  an  Exclusive  License  and  Commercialization  Agreement  (the  “Collaboration
Agreement”) with Junshi Biosciences for the co-development and commercialization of toripalimab, Junshi Biosciences’ anti-PD-
1 antibody in the United States and Canada (the “Collaboration”).

Under  the  terms  of  the  Collaboration  Agreement,  we  will  pay  $150.0  million  upfront  for  exclusive  rights  to  toripalimab
in  the  United  States  and  Canada,  options  in  these  territories  to  Junshi  Biosciences’  anti-TIGIT  antibody  and  next-generation
engineered  IL-2  cytokine,  and  certain  negotiation  rights  to  two  undisclosed  preclinical  immuno-oncology  drug  candidates.  We
will have the right to conduct all commercial activities of toripalimab in the United States and Canada. We will be obligated to pay
Junshi Biosciences a 20% royalty on net sales of toripalimab and up to an aggregate $380.0 million in one-time payments for the
achievement of various milestones, including up to $290.0 million for attainment of certain sales thresholds. If we exercise our
options,  we  will  be  obligated  to  pay  an  option  exercise  fee  for  each  of  the  anti-TIGIT  antibody  and  the  IL-2  cytokine  of  $35.0
million per program. Additionally, for each exercised option, we will

of the consideration for the Collaboration.

Intellectual Property

Our  commercial  success  depends  in  part  on  our  ability  to  avoid  infringing  the  proprietary  rights  of  third  parties.
Additionally,  our  commercial  success  may  depend  on  our  ability  to  obtain  and  maintain  proprietary  protection  for  our
technologies  where  applicable  and  to  prevent  others  from  infringing  our  proprietary  rights.  We  seek  to  protect  our  proprietary
technologies by, among other methods, filing U.S. and international patent applications on these technologies, inventions and
improvements  that  are  important  to  our  business.  We  also  rely  on  trade  secrets,  know-how  and  continuing  technological
innovation to develop and maintain our proprietary position.

The  term  of  individual  patents  depends  upon  the  legal  term  of  the  patents  in  countries  in  which  they  are  obtained.  In
most countries, including the U.S., the patent term is generally 20 years from the earliest date of filing a non-provisional patent
application in the applicable country. In the U.S., a patent’s term may, in certain cases, be lengthened by patent term adjustment,
which compensates a patentee for administrative delays by the U.S. Patent and Trademark Office in examining and granting a
patent or may be shortened if a patent is terminally disclaimed over a commonly owned patent or a patent naming a common
inventor and having an earlier expiration date.

In the normal course of business, we pursue patent protection for inventions related to our product candidates. We own
a patent portfolio of 25 patent families related to our biosimilar product candidates. Each patent family includes United States
patent  applications  and/or  issued  patents,  and  some  include  foreign  counterparts  to  certain  of  the  U.S.  patents  and  patent
applications.  Our  patent  portfolio  includes  issued  or  pending  claims  directed  to  formulations,  methods  of  manufacturing
biological proteins, and drug products and devices, including their methods of use and methods of manufacture.

In  a  merger  completed  February  12,  2014,  we  acquired  InteKrin  Therapeutics  Inc.  (“InteKrin”)  and  its  small  molecule

PPAR-g modulator, CHS-131, which is being developed for the treatment of NASH.

InteKrin has an exclusive license from Amgen to a portfolio of four patent families related to CHS-131, each of which
includes U.S. patents and some include foreign counterparts to certain of the U.S. patents. The licensed patent portfolio includes
issued  claims  directed  to  PPAR-γ  modulating  molecules  and  therapeutic  product  compositions  that  are  expected  to  expire  in
2020 and 2021, as well as certain salt forms and polymorphic forms directed to PPAR-g modulating molecules that are expected
to expire in 2024. Additionally, we and our subsidiary InteKrin own a portfolio of 23 patent families related to CHS-131, each of
which  includes  U.S.  patent  applications  and/or  issued  patents,  and  some  include  foreign  counterparts  to  certain  of  the  U.S.
patents  and  patent  applications.  This  patent  portfolio  includes  issued  or  pending  claims  directed  to  PPAR-g  agonist
pharmaceutical  compositions,  and  methods  of  treating  disorders  including  diabetes,  multiple  sclerosis,  nonalcoholic
steatohepatitis, blood cancers, bone disorders, Huntington’s disease, and progressive supranuclear palsy.

Upon the first FDA approval for a CHS-131 product, we intend to seek a Hatch-Waxman patent term extension of CHS-
131 related patents. A Hatch-Waxman patent term extension can only be applied to a patent that is not expired at the time of
FDA  approval.  Additionally,  any  such  extension  cannot  be  longer  than  five  years  and  the  total  patent  term,  including  the
extension period, must not exceed fourteen years following FDA approval. For a discussion of risks related to our proprietary
technology and processes, please see “Risk Factors — Risks Related to Intellectual Property.”

Government Regulation

Our  operations  and  activities  are  subject  to  extensive  regulation  by  numerous  government  authorities  in  the  U.S.,  the
European  Union  and  other  countries,  including  laws  and  regulations  governing  the  testing,  manufacture,  safety,  efficacy,
labeling, storage, record keeping, approval, advertising and promotion of our products. As a result of these regulations, product
development and product approval processes are very expensive and time consuming. The regulatory requirements applicable
to drug development and approval are subject to change. Any legal and regulatory changes may impact our operations in the
future. A country’s regulatory agency, such as the FDA in the United States and the EMA or the European Commission for the
European  Union,  must  approve  a  drug  before  it  can  be  sold  in  the  respective  country  or  countries.  The  general  process  for
biosimilar approval in the United States is summarized below. Many other countries, including countries in the European Union,
have similar regulatory structures.

FDA Approval Process for Drugs and Biologics

All of our current product candidates are subject to regulation in the U.S. by the FDA as biological products (“biologics”),
except for CHS-131, which is regulated as a drug product candidate. The FDA subjects drugs and biologics to extensive pre-
and post-market regulation pursuant to the Federal Food, Drug and Cosmetic Act (“FFDCA”) and its implementing regulations,
and  in  the  case  of  biologics,  the  FFDCA  and  the  Public  Health  Service  Act  (“PHSA”)  and  their  implementing  regulations.  In
addition, we are subject to other federal and state statutes and regulations. These laws and regulations govern, among other
things, the research, development, testing, manufacture, storage, recordkeeping, approval, labeling, promotion and marketing,
distribution, post-approval monitoring and reporting, sampling and import and export of drugs and biologics. Failure to comply
with  applicable  U.S.  requirements  may  subject  a  company  to  a  variety  of  administrative  or  judicial  sanctions,  such  as  FDA
refusal  to  approve  a  pending  BLAs  or  NDAs,  withdrawal  of  approvals,  clinical  holds,  warning  letters,  product  recalls,  product
seizures, total or partial suspension of production or distribution, injunctions, fines, civil penalties or criminal penalties.

The  process  required  by  the  FDA  before  a  new  biologic  or  drug  may  be  marketed  in  the  U.S.  is  long,  expensive  and
inherently  uncertain.  Biologic  and  drug  development  in  the  U.S.  typically  involves  the  completion  of  preclinical  laboratory  and
animal  tests  in  accordance  with  good  laboratory  practices  (“GLP”),  the  submission  to  the  FDA  of  an  investigational  new  drug
(“IND”) application, which must become effective before clinical testing may commence, the performance of adequate and well-
controlled  clinical  trials  to  establish  the  safety  and  effectiveness  of  the  biologic  or  drug  for  each  indication  for  which  FDA
approval is sought in compliance with good clinical practice (“GCP”) requirements, the submission to the FDA of an original BLA
under Section 351(a) of the PHSA (“original BLA”) or an NDA, as appropriate, satisfactory completion of an FDA inspection of
the manufacturing facility or facilities at which the drug or biologic is produced, and FDA approval and review of the original BLA
or NDA. Developing the data to satisfy FDA pre-market approval requirements typically takes many years and the actual time
required may vary substantially based upon the type, complexity and novelty of the product or disease.

Preclinical  tests  include  laboratory  evaluation  of  product  chemistry,  formulation  and  toxicity,  as  well  as  animal  trials  to
assess the characteristics and potential safety and efficacy of the product. The conduct of the preclinical tests must comply with
federal  regulations  and  requirements,  including  GLP.  An  IND  is  a  request  for  authorization  from  the  FDA  to  administer  an
investigational new drug or biologic to humans. The central focus of an IND submission is on the general investigational plan
and the protocol(s) for human studies, although the IND must also include the results of preclinical testing and animal testing
assessing  the  toxicology,  PK,  pharmacology  and  PD  characteristics  of  the  product  along  with  other  information,  including
information  about  product  chemistry,  manufacturing  and  controls  and  a  proposed  clinical  trial  protocol.  Long-term  preclinical
tests, such as animal tests of reproductive toxicity and carcinogenicity, may continue after the IND is submitted.

An IND must become effective before U.S. clinical trials may begin. A 30-day waiting period after the submission of each
IND  is  required  prior  to  the  commencement  of  clinical  testing  in  humans.  If  during  the  30-day  waiting  period  the  FDA  raises
concerns or questions related to the proposed clinical studies, the sponsor and the FDA must resolve any outstanding concerns
or questions before clinical studies can begin. If the FDA has neither commented on nor questioned the IND within this 30-day
period, the clinical trial proposed in the IND may begin.

Clinical trials involve the administration of the investigational new drug or biologic to healthy volunteers or patients with
the  condition  under  investigation,  all  under  the  supervision  of  a  qualified  investigator.  Clinical  trials  must  be  conducted:  (i)  in
compliance  with  federal  regulations;  (ii)  in  compliance  with  GCP  requirements,  which  are  designed  to  protect  the  rights  and
health of patients and to define the roles of clinical trial sponsors, administrators and monitors; as well as (iii) under protocols
detailing the objectives of the trial, the

11

Table of Contents

parameters to be used in monitoring safety and the effectiveness criteria to be evaluated. Each protocol involving testing on U.S.
patients and subsequent protocol amendments must be submitted to the FDA as part of the IND.

Human clinical trials for novel drugs and biologics are typically conducted in three sequential phases that may overlap or

be combined.

● Phase  1—The  product  candidate  is  initially  introduced  into  healthy  human  subjects  and  tested  for  safety,  dosage
tolerance,  absorption,  metabolism,  distribution  and  elimination.  In  the  case  of  some  therapeutic  candidates  for
severe or life-threatening diseases, such as cancer, especially when the product candidate may be inherently too
toxic to ethically administer to healthy volunteers, the initial human testing is often conducted in patients.

● Phase 2—Clinical trials are performed on a limited patient population intended to identify possible adverse effects
and safety risks, to preliminarily evaluate the efficacy of the product for specific targeted diseases and to determine
dosage tolerance and optimal dosage.

● Phase  3—Clinical  trials  are  undertaken  to  further  evaluate  dosage,  clinical  efficacy  and  safety  in  an  expanded
patient  population  at  geographically  dispersed  clinical  study  sites.  These  studies  are  intended  to  establish  the
overall risk-benefit ratio of the product and provide an adequate basis for product labeling.

Post-approval trials, sometimes referred to as “Phase 4” clinical trials, may be conducted after initial marketing approval.
These  trials  are  used  to  gain  additional  experience  from  the  treatment  of  patients  in  the  intended  therapeutic  indication.  In
certain instances, FDA may mandate the performance of such “Phase 4” clinical trials.

The FDA may order the temporary or permanent discontinuation of a clinical trial at any time or impose other sanctions if
it believes that the clinical trial either is not being conducted in accordance with FDA requirements or presents an unacceptable
risk to the clinical trial patients. The study protocol and informed consent information for patients in clinical trials must also be
submitted to an institutional review board (“IRB”), for approval. An IRB may also require the clinical trial at the site to be halted,
either temporarily or permanently, for failure to comply with the IRB’s requirements or may impose other conditions. The study
sponsor may also suspend a clinical trial at any time on various grounds, including a determination that the subjects or patients
are being exposed to an unacceptable health risk.

Concurrent with clinical trials, sponsors usually complete additional animal safety studies, develop additional information
about the chemistry and physical characteristics of the product candidate and finalize a process for manufacturing commercial
quantities  of  the  product  candidate  in  accordance  with  cGMP  requirements.  The  manufacturing  process  must  be  capable  of
consistently  producing  quality  batches  of  the  product  candidate  and  the  manufacturer  must  develop  methods  for  testing  the
quality, purity and potency of the product candidate. To help reduce the risk of the introduction of adventitious agents with use of
biological  products,  the  PHSA  emphasizes  the  importance  of  manufacturing  control  for  products  whose  attributes  cannot  be
precisely  defined.  The  manufacturing  process  must  be  capable  of  consistently  producing  quality  batches  of  the  product
candidate  and,  among  other  criteria,  the  sponsor  must  develop  methods  for  testing  the  identity,  strength,  quality,  potency  and
purity of the final biological product. Additionally, appropriate packaging must be selected and tested, and stability studies must
be conducted to demonstrate that the biological product candidate does not undergo unacceptable deterioration over its shelf
life. Additionally, for both NDA and BLA products, appropriate packaging must be selected and tested and stability studies must
be conducted to demonstrate that the product candidate does not undergo unacceptable deterioration over its proposed shelf-
life.

Assuming  successful  completion  of  all  required  testing  in  accordance  with  all  applicable  regulatory  requirements,
detailed  information  regarding  the  investigational  product  is  submitted  to  the  FDA  in  the  form  of  a  BLA  or  NDA  requesting
approval  to  market  the  product  for  one  or  more  indications.  The  BLA  or  NDA  must  include  all  relevant  data  available  from
pertinent preclinical and clinical trials, including negative or ambiguous results as well as positive findings, together with detailed
information  relating  to  the  product’s  chemistry,  manufacturing,  controls,  and  proposed  labeling,  among  other  things.  Data  can
come from company-sponsored clinical studies intended to test the safety and effectiveness of a use of the product, or from a
number of alternative sources, including studies initiated by investigators. Under the Prescription Drug User Fee Act (“PDUFA”)
as amended, each original BLA or NDA must be accompanied by a significant user fee. Fee waivers or reductions are available
in  certain  circumstances,  such  as  where  a  waiver  is  necessary  to  protect  the  public  health,  where  the  fee  would  present  a
significant barrier to innovation, or where the applicant is a small business submitting its first human therapeutic application for
review.

Table of Contents

Within 60 days following submission of the application, the FDA reviews an original BLA or NDA submitted to determine
if it is substantially complete before the agency accepts it for filing. The FDA may refuse to file any original BLA or NDA that it
deems incomplete or not properly reviewable at the time of submission, and may request additional information. In this event,
the  original  BLA  or  NDA  must  be  resubmitted  with  the  additional  information.  The  resubmitted  application  also  is  subject  to
review before the FDA accepts it for filing. Once the submission is accepted for filing, the FDA begins an in-depth substantive
review of the original BLA or NDA. The FDA reviews the original BLA to determine, among other things, whether the proposed
product is safe, pure and potent for its intended use, and has an acceptable purity profile, and in the case of an NDA, whether
the  product  is  safe  and  effective  for  its  intended  use,  and  in  each  case,  whether  the  product  is  being  manufactured  in
accordance with cGMP. The FDA may refer applications for novel products or products that present difficult questions of safety
or  efficacy  to  an  advisory  committee,  typically  a  panel  that  includes  clinicians  and  other  experts,  for  review,  evaluation  and  a
recommendation  as  to  whether  the  application  should  be  approved  and  under  what  conditions.  The  FDA  is  not  bound  by  the
recommendations of an advisory committee, but it considers such recommendations carefully when making decisions.

During  the  product  approval  process,  the  FDA  also  will  determine  whether  a  risk  evaluation  and  mitigation  strategy
(“REMS”) is necessary to assure the safe use of the product. If the FDA concludes a REMS plan is needed, the sponsor of the
original BLA or NDA must submit a proposed REMS plan. The FDA will not approve an original BLA or NDA without a REMS
plan, if required. In determining whether a REMS plan is necessary, the FDA must consider the size of the population likely to
use the drug or biologic, the seriousness of the disease or condition to be treated, the expected benefit of the drug or biologic,
the  duration  of  treatment,  the  seriousness  of  known  or  potential  adverse  events,  and  whether  the  drug  or  biologic  is  a  new
molecular  entity.  A  REMS  plan  may  be  required  to  include  various  elements,  such  as  a  medication  guide  or  patient  package
insert,  a  communication  plan  to  educate  health  care  providers  of  the  risks,  limitations  on  who  may  prescribe  or  dispense  the
drug or biologic, or other measures that the FDA deems necessary to assure the safe use of the drug or biologic. In addition, the
REMS  plan  must  include  a  timetable  to  assess  the  strategy  at  18  months,  three  years,  and  seven  years  after  the  strategy’s
approval.

The  FDA  will  not  approve  the  application  unless  it  determines  that  the  manufacturing  processes  and  facilities  are  in
compliance with cGMP requirements and adequate to assure consistent production of the product within required specifications.
Additionally,  before  approving  an  original  BLA  or  NDA,  the  FDA  will  typically  inspect  one  or  more  clinical  sites  to  assure
compliance  with  cGCP.  After  the  FDA  evaluates  an  original  BLA  or  NDA  and  conducts  inspections  of  manufacturing  facilities
where  the  investigational  product  and/or  its  drug  substance  will  be  produced,  the  FDA  may  issue  an  approval  letter  or  a
complete response letter. An approval letter authorizes commercial marketing of the product with specific prescribing information
for  specific  indications.  A  complete  response  letter  indicates  that  the  review  cycle  of  the  application  is  complete  and  the
application is not ready for approval. A complete response letter may require additional clinical data and/or an additional pivotal
Phase 3 trial or trials, and/or other significant, expensive and time-consuming requirements related to clinical trials, preclinical
trials or manufacturing. Even if such additional information is submitted, the FDA may ultimately decide that the original BLA or
NDA does not satisfy the criteria for approval.

Even  if  a  product  receives  regulatory  approval,  the  approval  may  be  significantly  limited  to  specific  indications  and
dosages or the indications for use may otherwise be limited, which could restrict the commercial value of the product. Further,
the FDA may require that certain contraindications, warnings or precautions be included in the product labeling. The FDA may
impose restrictions and conditions on product distribution, prescribing, or dispensing in the form of a risk management plan, or
otherwise limit the scope of any approval. In addition, the FDA may require post marketing clinical trials, sometimes referred to
as  “Phase  4”  clinical  trials,  designed  to  further  assess  a  biological  product’s  safety  and  effectiveness,  and  testing  and
surveillance programs to monitor the safety of approved products that have been commercialized.

Abbreviated Licensure Pathway of Biological Products as Biosimilar under 351(k)

The Biologics Price Competition and Innovation Act of 2009 (“BPCIA”), amended the PHSA and created an abbreviated
approval pathway for biological products shown to be highly similar to a FDA-licensed reference biological product. The BPCIA
attempts  to  minimize  duplicative  testing  and  thereby  lower  development  costs  and  increase  patient  access  to  affordable
treatments. Thus, an application for licensure of a biosimilar product pursuant to a Section 351(k) BLA must include information
demonstrating biosimilarity based upon the following, unless the FDA determines otherwise:

● analytical  studies  demonstrating  that  the  proposed  biosimilar  product  is  highly  similar  to  the  approved  product

notwithstanding minor differences in clinically inactive components;

● animal studies (including the assessment of toxicity); and

13

Table of Contents

● two clinical study phases: first, a clinical study or studies (generally termed “Phase 1”) that demonstrate the PK and
PD  similarity  (e.g.,  bioequivalence  study)  of  the  proposed  biosimilar  to  the  originator  molecule,  and  second,  a
clinical study or studies (generally termed “Phase 3”) that demonstrate the safety (including immunogenicity), purity
and that potency is statistically not inferior to that of the originator in one or more conditions for which the reference
product is licensed and intended to be used.

In addition, an application submitted under the 351(k) pathway must include information demonstrating that:

● the proposed biosimilar product and reference product utilize the same mechanism of action for the condition(s) of
use prescribed, recommended or suggested in the proposed labeling, but only to the extent the mechanism(s) of
action are known for the reference product;

● the condition or conditions of use prescribed, recommended or suggested in the labeling for the proposed biosimilar

product have been previously approved for the reference product;

● the route of administration, the dosage form and the strength of the proposed biosimilar product are the same as

those for the reference product; and

● the facility in which the biological product is manufactured, processed, packed or held meets standards designed to

assure that the biological product continues to be safe, pure and potent.

Biosimilarity  is  defined  to  mean  that  the  proposed  biological  product  is  highly  similar  to  the  reference  product
notwithstanding  minor  differences  in  clinically  inactive  components  and  that  there  are  no  clinically  meaningful  differences
between the biological product and the reference product in terms of the safety, purity and potency of the product. In addition,
biosimilar  may  also  be  determined  to  be  “interchangeable”  with  the  reference  products,  whereby  the  biosimilar  may  be
substituted for the reference product without the intervention of the health care provider who prescribed the reference product.
The higher standard of interchangeability must be demonstrated by information sufficient to show that:

● the proposed product is biosimilar to the reference product;

● the proposed product is expected to produce the same clinical result as the reference product in any given patient;

and

● for  a  product  that  is  administered  more  than  once  to  an  individual,  the  risk  to  the  patient  in  terms  of  safety  or
diminished efficacy of alternating or switching between the biosimilar and the reference product is no greater than
the risk of using the reference product without such alternation or switch.

FDA  approval  is  required  before  a  biosimilar  may  be  marketed  in  the  U.S.  However,  complexities  associated  with  the
large and intricate structures of biological products and the process by which such products are manufactured pose significant
hurdles to the FDA’s implementation of the 351(k) approval pathway that are still being worked out by the FDA. For example, the
FDA  has  discretion  over  the  kind  and  amount  of  scientific  evidence  —  laboratory,  preclinical  and/or  clinical  —  required  to
demonstrate biosimilarity to a licensed biological product. The FDA intends to consider the totality of the evidence, provided by a
sponsor  to  support  a  demonstration  of  biosimilarity,  and  recommends  that  sponsors  use  a  stepwise  approach  in  the
development  of  their  biosimilar  products.  Biosimilar  product  applications  thus  may  not  be  required  to  duplicate  the  entirety  of
preclinical and clinical testing used to establish the underlying safety and effectiveness of the reference product. However, the
FDA may refuse to approve a biosimilar application if there is insufficient information to show that the active ingredients are the
same or to demonstrate that any impurities or differences in active ingredients do not affect the safety, purity or potency of the
biosimilar product. In addition, as with original BLAs, biosimilar product applications will not be approved unless the product is
manufactured in facilities designed to assure and preserve the biological product’s safety, purity and potency.

The submission of an application via the 351(k) pathway does not guarantee that the FDA will accept the application for
filing  and  review,  as  the  FDA  may  refuse  to  accept  applications  that  it  finds  are  incomplete.  The  FDA  will  treat  a  biosimilar
application or supplement as incomplete if, among other reasons, any applicable user fees assessed under the Biosimilar User
Fee Amendment of 2017 have not been paid. In addition, the FDA may accept an application for filing but deny approval on the
basis that the sponsor has not demonstrated

14

Table of Contents

biosimilarity, in which case the sponsor may choose to conduct further analytical, preclinical or clinical studies to demonstrate
such  biosimilarity  under  Section  351(k)  or  submit  an  original  BLA  for  licensure  as  a  new  biological  product  under  section
351(a) of the PHSA.

The  timing  of  final  FDA  approval  of  a  biosimilar  for  commercial  distribution  depends  on  a  variety  of  factors,  including
whether the manufacturer of the branded product is entitled to one or more statutory exclusivity periods, during which time the
FDA is prohibited from approving any products that are biosimilar to the branded product. The FDA cannot approve a biosimilar
application for 12 years from the date of first licensure of the reference product. Additionally, a biosimilar product sponsor may
not  submit  an  application  under  the  351(k)  pathway  for  four  years  from  the  date  of  first  licensure  of  the  reference  product.  In
certain circumstances, a regulatory exclusivity period can extend beyond the life of a patent and thus block Section 351(k) BLA
from  being  approved  on  or  after  the  patent  expiration  date.  In  addition,  the  FDA  may  under  certain  circumstances  extend  the
exclusivity period for the reference product by an additional six months if the FDA requests, and the manufacturer undertakes,
studies on the effect of its product in children, a so-called pediatric extension.

The  first  biological  product  determined  to  be  interchangeable  with  a  branded  product  for  any  condition  of  use  is  also
entitled to a period of exclusivity, during which time the FDA may not determine that another product is interchangeable with the
reference  product  for  any  condition  of  use.  This  exclusivity  period  extends  until  the  earlier  of:  (1)  one  year  after  the  first
commercial marketing of the first interchangeable product; (2) 18 months after resolution of a patent infringement suit instituted
under 42 U.S.C. § 262(l)(6) against the applicant that submitted the application for the first interchangeable product, based on a
final  court  decision  regarding  all  of  the  patents  in  the  litigation  or  dismissal  of  the  litigation  with  or  without  prejudice;
(3) 42 months after approval of the first interchangeable product, if a patent infringement suit instituted under 42 U.S.C. § 262(l)
(6) against the applicant that submitted the application for the first interchangeable product is still ongoing; or (4) 18 months after
approval of the first interchangeable product if the applicant that submitted the application for the first interchangeable product
has not been sued under 42 U.S.C. § 262(l)(6).

Advertising and Promotion

Once an NDA, original BLA, or 351(k) BLA is approved, a product will be subject to continuing post-approval regulatory
requirements, including, among other things, requirements relating to recordkeeping, periodic reporting, product sampling and
distribution,  advertising  and  promotion  and  reporting  of  adverse  experiences  with  the  product.  For  instance,  the  FDA  closely
regulates  the  post-approval  marketing  and  promotion  of  biologics,  including  standards  and  regulations  for  direct-to-consumer
advertising, off-label promotion, industry-sponsored scientific and educational activities and promotional activities involving the
internet.  Failure  to  comply  with  these  regulations  can  result  in  significant  penalties,  including  the  issuance  of  warning  letters
directing a company to correct deviations from FDA standards, a requirement that future advertising and promotional materials
be pre-cleared by the FDA and federal and state civil and criminal investigations and prosecutions.

Biologics  and  drugs  may  be  marketed  only  for  the  approved  indications  and  in  accordance  with  the  provisions  of  the
approved  labeling.  After  approval,  most  changes  to  the  approved  product,  including  changes  in  indications,  labeling  or
manufacturing processes or facilities, require submission and FDA approval of a new marketing application or supplement to the
approved  marketing  application  before  the  change  can  be  implemented.  A  supplement  for  a  new  indication  typically  requires
clinical  data  similar  to  that  in  the  original  application,  and  the  FDA  uses  the  same  procedures  and  actions  in  reviewing
supplements  as  it  does  in  reviewing  original  application.  There  are  also  continuing  annual  program  user  fee  requirements  for
marketed products.

Adverse Event Reporting and GMP Compliance

Adverse  event  reporting  and  submission  of  periodic  reports  are  required  following  FDA  approval  of  a  marketing
application. The FDA also may require post-market testing, including Phase 4 testing, a REMS, and surveillance to monitor the
effects of an approved product, or the FDA may place conditions on an approval that could restrict the distribution or use of the
product. In addition, manufacture, packaging, labeling, storage and distribution procedures must continue to conform to cGMPs
after approval. Manufacturers and certain of their subcontractors are required to register their establishments with the FDA and
certain  state  agencies.  Registration  with  the  FDA  subjects  entities  to  periodic  unannounced  inspections  by  the  FDA,  during
which the agency inspects manufacturing facilities to assess compliance with cGMPs. Accordingly, manufacturers must continue
to expend time, money and effort in the areas of production and quality control to maintain compliance with cGMPs. Regulatory
authorities may withdraw product approvals, request product recalls or impose marketing restrictions through labeling changes
or product removals if a company fails to comply with regulatory standards, if it encounters problems following initial marketing
or if previously unrecognized problems are subsequently discovered.

15

Table of Contents

The  FDA  may  withdraw  approval  if  compliance  with  regulatory  requirements  and  standards  is  not  maintained  or  if
problems occur after the product reaches the market. Later discovery of previously unknown problems with a product, including
adverse  events  of  unanticipated  severity  or  frequency  or  with  manufacturing  processes  or  failure  to  comply  with  regulatory
requirements, may result in revisions to the approved labeling to add new safety information; imposition of post-market studies
or  clinical  studies  to  assess  new  safety  risks;  or  imposition  of  distribution  restrictions  or  other  restrictions  under  a  REMS
program. Other potential consequences include, among other things:

● restrictions on the marketing or manufacturing of the product, complete withdrawal of the product from the market or

product recalls;

● fines, warning letters or holds on post-approval clinical trials;

● refusal  of  the  FDA  to  approve  pending  applications  or  supplements  to  approved  applications  or  suspension  or

revocation of product license approvals;

● product seizure or detention or refusal to permit the import or export of products; or

● injunctions or the imposition of civil or criminal penalties.

Other Healthcare Laws and Compliance Requirements

We  are  subject  to  healthcare  regulation  and  enforcement  by  the  federal  government  and  the  states  and  foreign
governments in which we conduct our business. These laws include, without limitation, state and federal anti-kickback, fraud and
abuse, false claims, privacy and security and transparency laws and regulations.

The  federal  Anti-Kickback  Statute  prohibits,  among  other  things,  any  person  from  knowingly  and  willfully  offering,
soliciting, receiving or providing remuneration, directly or indirectly, to induce either the referral of an individual, for an item or
service or the purchasing or ordering of a good or service, for which payment may be made under federal healthcare programs
such as the Medicare and Medicaid programs. The Anti-Kickback Statute is subject to evolving interpretations. In the past, the
government  has  enforced  the  Anti-Kickback  Statute  to  reach  large  settlements  with  healthcare  companies  based  on  sham
consulting and other financial arrangements with physicians. Further, a person or entity does not need to have actual knowledge
of the statutes or specific intent to violate it in order to have committed a violation. The majority of states also have anti-kickback
laws, which establish similar prohibitions and in some cases may apply to items or services reimbursed by any third-party payer,
including commercial insurers.

Additionally,  federal  civil  and  criminal  false  claims  laws,  including  the  civil  False  Claims  Act,  prohibit  knowingly
presenting or causing the presentation of a false, fictitious or fraudulent claim for payment to the U.S. government. Actions under
the False Claims Act may be brought by the Attorney General or as a qui tam action by a private individual in the name of the
government.  In  addition,  the  government  may  assert  that  a  claim  including  items  or  services  resulting  from  a  violation  of  the
federal Anti-Kickback Statute constitutes a false or fraudulent claim for purposes of the federal False Claims Act. Violations of
the False Claims Act can result in very significant monetary penalties and treble damages. The federal government is using the
False Claims Act, and the accompanying threat of significant liability, in its investigation and prosecution of pharmaceutical and
biotechnology companies throughout the country, for example, in connection with the promotion of products for unapproved uses
and other sales and marketing practices. The government has obtained multi-million and multi-billion dollar settlements under
the False Claims Act in addition to individual criminal convictions under applicable criminal statutes. Given the significant size of
actual and potential settlements, it is expected that the government will continue to devote substantial resources to investigating
healthcare providers’ and manufacturers’ compliance with applicable fraud and abuse laws.

The federal Civil Monetary Penalties Law prohibits, among other things, the offering or transferring of remuneration to a
Medicare  or  Medicaid  beneficiary  that  the  person  knows  or  should  know  is  likely  to  influence  the  beneficiary’s  selection  of  a
particular  supplier  of  Medicare  or  Medicaid  payable  items  or  services.  Noncompliance  with  such  beneficiary  inducement
provision of the federal Civil Monetary Penalties Law can result in civil money penalties for each wrongful act, assessment of
three times the amount claimed for each item or service and exclusion from the federal healthcare programs.

Federal  and  state  government  price  reporting  laws  require  manufacturers  to  calculate  and  report  complex  pricing
metrics  to  government  programs.  Such  reported  prices  may  be  used  in  the  calculation  of  reimbursement  and/or  discounts  on
marketed products.

16

Table of Contents

Participation in these programs and compliance with the applicable requirements subject manufacturers to potentially significant
discounts on products, increased infrastructure costs, and potentially limit the ability to offer certain marketplace discounts.

In addition, there has been a recent trend of increased federal and state regulation of payments made to physicians and
other  healthcare  providers.  The  Patient  Protection  and  Affordable  Care  Act,  as  amended  by  the  Health  Care  and  Education
Reconciliation Act (collectively, the “ACA”), among other things, imposed new reporting requirements on drug manufacturers for
payments  made  by  them  to  physicians  (defined  to  include  doctors,  dentists,  optometrists,  podiatrists  and  chiropractors)  and
teaching hospitals, as well as ownership and investment interests held by such physicians and their immediate family members.
Beginning in 2022, these reporting obligations will extend to include payments and transfers of value made during the previous
year  to  physician  assistants,  nurse  practitioners,  clinical  nurse  specialists,  certified  registered  nurse  anesthetists  and
anesthesiologist  assistants,  and  certified  nurse  midwives.  Failure  to  submit  required  information  may  result  in  significant  civil
monetary penalties for any payments, transfers of value or ownership or investment interests that are not timely, accurately and
completely  reported  in  an  annual  submission,  and  additional  penalties  for  “knowing  failures.”  Certain  states  also  mandate
implementation  of  commercial  compliance  programs,  impose  restrictions  on  pharmaceutical  manufacturer  marketing  practices
and/or require the tracking and reporting of gifts, compensation and other remuneration to physicians.

The federal Health Insurance Portability and Accountability Act of 1996 (“HIPAA”) created new federal criminal statutes
that  prohibit  among  other  actions,  knowingly  and  willfully  executing,  or  attempting  to  execute,  a  scheme  to  defraud  any
healthcare benefit program, including private third‑party payers, knowingly and willfully embezzling or stealing from a healthcare
benefit  program,  willfully  obstructing  a  criminal  investigation  of  a  healthcare  offense,  and  knowingly  and  willfully  falsifying,
concealing or covering up a material fact or making any materially false, fictitious or fraudulent statement in connection with the
delivery of or payment for healthcare benefits, items or services. Similar to the federal Anti‑Kickback Statute, a person or entity
does not need to have actual knowledge of the statute or specific intent to violate it in order to have committed a violation.

We may also be subject to data privacy and security regulation by both the federal government and the states in which
we  conduct  our  business.  HIPAA,  as  amended  by  the  Health  Information  Technology  and  Clinical  Health  Act  (“HITECH”)  and
their respective implementing regulations, imposes specified requirements relating to the privacy, security and transmission of
individually identifiable health information. Among other things, HITECH makes HIPAA’s privacy and security standards directly
applicable  to  “business  associates,”  defined  as  independent  contractors  or  agents  of  covered  entities  that  create,  receive,
maintain  or  transmit  protected  health  information  in  connection  with  providing  a  service  for  or  on  behalf  of  a  covered  entity.
HITECH also increased the civil and criminal penalties that may be imposed against covered entities, business associates and
possibly other persons, and gave state attorneys general new authority to file civil actions for damages or injunctions in federal
courts to enforce the federal HIPAA laws and seek attorney’s fees and costs associated with pursuing federal civil actions. In
addition,  state  laws  govern  the  privacy  and  security  of  health  information  in  certain  circumstances,  many  of  which  differ  from
each other in significant ways, thus complicating compliance efforts. By way of example, the California Consumer Privacy Act, or
the CCPA, effective January 1, 2020, gives California residents expanded rights to access and delete their personal information,
opt out of certain personal information sharing, and receive detailed information about how their personal information is used.
The  CCPA  provides  for  civil  penalties  for  violations,  as  well  as  a  private  right  of  action  for  data  breaches  that  is  expected  to
increase data breach litigation. Further, the California Privacy Rights Act (“CPRA”) recently passed in California. The CPRA will
impose additional data protection obligations on covered businesses, including additional consumer rights processes, limitations
on data uses, new audit requirements for higher risk data, and opt outs for certain uses of sensitive data. It will also create a new
California  data  protection  agency  authorized  to  issue  substantive  regulations  and  could  result  in  increased  privacy  and
information security enforcement. The majority of the provisions will go into effect on January 1, 2023, and additional compliance
investment and potential business process changes may be required. The CCPA and the CPRA may increase our compliance
costs and potential liability.

Some states also require pharmaceutical companies to comply with the pharmaceutical industry’s voluntary compliance
guidelines and the relevant compliance guidance promulgated by the federal government and require manufacturers to report
information  related  to  payments  and  other  transfers  of  value  to  healthcare  providers  and  institutions  as  well  as  marketing
expenditures and pricing information.

The  shifting  commercial  compliance  environment  and  the  need  to  build  and  maintain  robust  systems  to  comply  with
different  compliance  and/or  reporting  requirements  in  multiple  jurisdictions  increase  the  possibility  that  a  healthcare  company
may violate one or more of the requirements. A violation of any of such laws or any other applicable governmental regulations
may result in penalties, including, without limitation, civil and criminal penalties, damages, fines, the curtailment or restructuring
of  our  operations,  exclusion  from  participation  in  federal  and  state  healthcare  programs,  additional  reporting  obligations  and
oversight  if  the  government  requires  a  corporate  integrity  agreement  or  other  agreement  to  resolve  allegations  of  non-
compliance with these laws, and/or imprisonment.

Pharmaceutical Coverage, Pricing and Reimbursement

In the U.S. and other countries, sales of any products for which we receive regulatory approval for commercial sale will
depend  in  part  on  the  availability  of  coverage  and  reimbursement  from  third-party  payers,  including  government  health
administrative  authorities,  managed  care  providers,  private  health  insurers  and  other  organizations.  Third-party  payers  are
increasingly examining the medical necessity and cost effectiveness of medical products and services in addition to safety and
efficacy  and,  accordingly,  significant  uncertainty  exists  as  to  the  reimbursement  status  of  newly  approved  therapeutics.  In
addition,  the  U.S.  government,  state  legislatures  and  foreign  governments  have  continued  implementing  cost-containment
programs,  including  price  controls,  restrictions  on  coverage  and  reimbursement  and  requirements  for  substitution  of  generic
products. Adoption of price controls and cost-containment measures and adoption of more restrictive policies in jurisdictions with
existing controls and measures could further limit our net revenue and results. Decreases in third-party reimbursement for our
product candidates or a decision by a third-party payer to not cover our product candidates could reduce physician utilization of
our products and have a material adverse effect on our sales, results of operations and financial condition.

The Centers for Medicare & Medicaid Services (“CMS”) adopted, effective January 1, 2018, a Medicare Part B rule on
biosimilar payment and coding, which requires that each biosimilar to the same reference product be issued a unique Q-code for
Medicare reimbursement purposes and that the payment amount for a billing code that describes a biosimilar is based on the
average sales price (“ASP”) specific to each biosimilar.

Healthcare Reform

In March 2010, the ACA was enacted, which substantially changed the way healthcare is financed by both governmental
and private insurers in the United States, and significantly affected the pharmaceutical industry. The ACA contained a number of
provisions,  including  those  governing  enrollment  in  federal  healthcare  programs,  reimbursement  adjustments  and  fraud  and
abuse changes. Additionally, the ACA subjected biologic products to potential competition by lower-cost biosimilars; increased
the minimum level of Medicaid rebates payable by manufacturers of brand name drugs from 15.1% to 23.1%; imposed a non-
deductible annual fee on pharmaceutical manufacturers or importers who sell “branded prescription drugs” to specified federal
government programs; and addressed a new methodology by which rebates owed by manufacturers under the Medicaid Drug
Rebate Program are calculated for drugs that are inhaled, infused, instilled, implanted or injected.

Since its enactment, there have been judicial and Congressional challenges to certain aspects of the ACA. For example,
on December 14, 2018, a U.S. District Court Judge in the Northern District of Texas, or Texas District Court Judge, ruled that the
entire Affordable Care Act is invalid based primarily on the fact that the Tax Cuts and Jobs Act of 2017 repealed the tax-based
shared responsibility payment imposed by the ACA, on certain individuals who fail to maintain qualifying health coverage for all
or part of a year, which is commonly referred to as the “individual mandate.” On December 18, 2019, the U.S. Court of Appeals
for the 5th Circuit upheld the District Court’s decision that the individual mandate was unconstitutional but remanded the case
back to the District Court to determine whether the remaining provisions of the ACA are invalid as well. The U.S. Supreme Court
is currently reviewing the case, although it is unclear how the Supreme Court will rule. It is also unclear how other efforts, if any,
to challenge, repeal or replace the ACA will impact the law.

Other legislative changes have been proposed and adopted since the ACA was enacted, including aggregate reductions
of Medicare payments to providers of 2% per fiscal year, which was temporarily suspended from May 1, 2020 through March 31,
2021, and reduced payments to several types of Medicare providers.

Moreover, there has recently been heightened governmental scrutiny over the manner in which manufacturers set prices
for  their  marketed  products,  which  has  resulted  in  several  Congressional  inquiries  and  proposed  and  enacted  legislation
designed  to,  among  other  things,  bring  more  transparency  to  product  pricing,  review  the  relationship  between  pricing  and
manufacturer  patient  programs,  and  reform  government  program  reimbursement  methodologies  for  drug  products.  Individual
states in the U.S. have also become increasingly active in implementing regulations designed to control pharmaceutical product
pricing,  including  price  or  patient  reimbursement  constraints,  discounts,  restrictions  on  certain  product  access  and  marketing
cost disclosure and transparency measures, and, in some cases, designed to encourage importation from other countries and
bulk purchasing.

Environment

We are subject to a number of laws and regulations that require compliance with federal, state, and local regulations for
the protection of the environment. The regulatory landscape continues to evolve, and we anticipate additional regulations in the
near  future.  Laws  and  regulations  are  implemented  and  under  consideration  to  mitigate  the  effects  of  climate  change  mainly
caused by greenhouse gas emissions. Our business is not energy intensive. Therefore, we do not anticipate being subject to a
cap  and  trade  system  or  other  mitigation  measure  that  would  materially  impact  our  capital  expenditures,  operations  or
competitive position.

Employees and Human Capital Resources

As of December 31, 2020, we had 317 employees. We believe we have good relations with our employees. Our human
capital resources objectives include, as applicable, identifying, recruiting, retaining, incentivizing and integrating our existing and
additional  employees.  The  principal  purposes  of  our  equity  incentive  plans  are  to  attract,  retain  and  motivate  selected
employees, consultants and directors through the granting of equity awards and cash-based performance bonus awards.

Risk Factor Summary

Below  is  a  summary  of  the  principal  factors  that  make  an  investment  in  our  common  stock  speculative  or  risky.  This
summary  does  not  address  all  of  the  risks  that  we  face.  Additional  discussion  of  the  risks  summarized  in  this  risk  factor
summary,  and  other  risks  that  we  face,  can  be  found  below  under  the  heading  “Risk  Factors”  and  should  be  carefully
considered, together with other information in this Annual

19

Table of Contents

Report  on  Form  10-K,  including  our  financial  statements  and  related  notes  thereto,  before  making  investment  decisions
regarding our common stock.

● Our  business,  financial  condition,  results  of  operations  and  growth  could  be  harmed  by  the  effects  of  the  COVID-19

pandemic.

● We have a limited operating history in an emerging regulatory environment on which to assess our business and we

have a limited history of profitability.

● The  commercial  success  of  UDENYCA®,  or  any  future  product  candidate,  will  depend  upon  the  degree  of  market
acceptance and adoption by healthcare providers, patients, third-party payers and others in the medical community.

● UDENYCA® and our other product candidates, even if approved, will remain subject to regulatory scrutiny.

● UDENYCA®, or our other biosimilar product candidates, if approved, will face significant competition from the reference
products  and  from  other  biosimilar  products  or  pharmaceuticals  approved  for  the  same  indication  as  the  originator
products.  Our  failure  to  effectively  compete  may  prevent  us  from  achieving  significant  market  penetration  and
expansion.

● We  face  intense  competition  and  rapid  technological  change  and  the  possibility  that  our  competitors  may  develop
therapies that are similar, more advanced or more effective than ours, which may adversely affect our financial condition
and our ability to successfully commercialize our product candidates.

● If  an  improved  version  of  an  originator  product,  such  as  Neulasta,  Humira,  Lucentis  or  Eylea,  is  developed  or  if  the
market for the originator product significantly declines, sales or potential sales of our biosimilar product candidates may
suffer.

● We  are  highly  dependent  on  the  services  of  our  key  executives  and  personnel,  including  our  President  and  Chief
Executive  Officer,  Dennis  M.  Lanfear,  and  if  we  are  not  able  to  retain  these  members  of  our  management  or  recruit
additional management, clinical and scientific personnel, our business will suffer.

● We  rely  on  third  parties  to  conduct  our  nonclinical  and  clinical  studies  and  perform  other  tasks  for  us.  If  these  third
parties  do  not  successfully  carry  out  their  contractual  duties,  meet  expected  deadlines  or  comply  with  regulatory
requirements, we may not be able to obtain regulatory approval for or commercialize our product candidates and our
business could be substantially harmed.

● We are subject to a multitude of manufacturing risks. Any adverse developments affecting the manufacturing operations
of our biosimilar product candidates could substantially increase our costs and limit supply for our product candidates.

● UDENYCA®  or  our  product  candidates  may  cause  undesirable  side  effects  or  have  other  properties  that  could,  as
applicable,  delay  or  prevent  their  regulatory  approval,  limit  the  commercial  profile  of  an  approved  label  or  result  in
significant negative consequences following marketing approval, if granted.

● If we infringe or are alleged to infringe intellectual property rights of third parties, our business could be harmed. Third-
party claims of intellectual property infringement may prevent or delay our development and commercialization efforts.

● We  are  heavily  dependent  on  the  development,  clinical  success,  regulatory  approval  and  commercial  success  of  our
product candidates. We cannot give any assurance that any of our product candidates will receive regulatory approval,
which is necessary before they can be commercialized.

Risk Factors

Investing  in  the  common  stock  of  a  biotherapeutics  company  is  a  highly  speculative  undertaking  and  involves  a
substantial  degree  of  risk.  You  should  consider  carefully  the  risks  and  uncertainties  described  below,  together  with  all  of  the
other information in this Annual Report on Form 10-K, including our financial statements and related notes thereto. If any of the
following  risks  are  realized,  our  business,  financial  condition,  results  of  operations  and  prospects  could  be  materially  and
adversely  affected.  As  a  result,  the  trading  price  of  our  common  stock  could  decline  and  you  could  lose  part  or  all  of  your
investment. The risks described below are not the only risks facing the Company. Risks and uncertainties not currently known to
us or that we currently deem to be immaterial also may materially adversely affect our business, financial condition, liquidity, and
results of operations and/or prospects.

Risks Related to COVID-19

Our business, financial condition, results of operations and growth could be harmed by the effects of the COVID-19
pandemic.

We are subject to risks related to public health crises such as the global pandemic associated with the novel coronavirus
and the associated disease (“COVID-19”). In December 2019, a novel strain of coronavirus, SARS-CoV-2, was reported to have
surfaced in Wuhan, China. Since then, SARS-CoV-2, and the resulting disease COVID-19, has spread to most countries, and all
50 states within the United States. As a result of the COVID-19 outbreak, we have experienced and may continue to experience
disruptions that could severely impact our business, clinical trials and preclinical studies, including, but not limited to:

● decreased sales of UDENYCA®;

● our  ability  to  maintain  or  expand  the  commercial  use  of  UDENYCA®  due  to,  among  other  factors,  healthcare
providers, payers and patients not utilizing or adopting UDENYCA® due to resources being strained or otherwise
focused on the COVID-19 pandemic and our sales team efficacy in selling UDENYCA® being limited due to such
strained resources or other factors such as travel restrictions;

● fewer individuals undertaking or completing cancer treatments, whether due to contracting COVID-19, self-isolating
or quarantining to lower the risk of contracting COVID-19 or being unable to access care as a result of healthcare
providers tending to COVID-19 patients;

● our third-party contract manufacturers and logistics providers not being able to maintain adequate (in amount and
quality) supply to support the commercial sale of UDENYCA® or the clinical development of our product candidates
due to staffing shortages, production slowdowns or stoppages and disruptions in delivery systems;

● delays and difficulties in clinical site initiation, including difficulties in recruiting clinical site investigators and clinical
site staff, as well as delays or difficulties in enrolling patients or maintaining enrolled patients in our clinical trials;

● interruption  of  key  clinical  trial  activities,  such  as  clinical  trial  site  data  monitoring,  due  to  limitations  on  travel
imposed  or  recommended  by  federal  or  state  governments,  employers  and  others  or  interruption  of  clinical  trial
subject  visits  and  study  procedures  (particularly  any  procedures  that  may  be  deemed  non-essential),  which  may
impact the integrity of subject data and clinical study endpoints;

● interruption or delays in the operations of the U.S. Food and Drug Administration and comparable foreign regulatory

agencies, which may impact regulatory review and approval timelines; and

● limitations on our employee resources, and those of our business partners, that would otherwise be focused on the

conduct of our business in all aspects, including because of sickness of employees or their families.

These  and  other  factors  arising  from  the  COVID-19  pandemic  could  result  in  us  not  being  able  to  maintain
UDENYCA®’s market position or increase its penetration against all Neulasta’s dosage forms, and could result in our inability to
meet development milestones for our product candidates, each of which would harm our business, financial condition, results of
operations and growth.

Numerous state and local jurisdictions have imposed, and others in the future may impose, “shelter-in-place” orders,

quarantines, executive orders and similar government orders and restrictions for their residents to control the spread of COVID-
19. Starting in mid-March 2020, the governor of California, where our headquarters and laboratory facilities are located, issued a
“shelter-in-place” order restricting non-essential activities, travel and business operations for an indefinite period of time, subject
to certain exceptions for necessary activities. Such orders or restrictions, have resulted in our headquarters closing, slowdowns
and delays,

21

Table of Contents

travel restrictions and cancellation of events, among other effects, thereby negatively impacting our operations. Such orders or
restrictions may be extended or re-instated, thereby causing additional negative impact on our operations.

While the long-term economic impact and the duration of the COVID-19 pandemic may be difficult to assess or predict,
the widespread pandemic has resulted in, and may continue to result in, significant disruption of global financial markets, which
could reduce our ability to access capital and could negatively affect our liquidity and the liquidity and stability of markets for our
common stock and the notes. In addition, a recession, further market correction or depression resulting from the spread
of COVID-19 could materially affect our business and the value of our notes and our common stock.

Risks Related to Our Financial Condition and Capital Requirements

We have a limited operating history in an emerging regulatory environment on which to assess our business and we
have a limited history of profitability.

We are a biopharmaceutical company with a limited operating history in an emerging regulatory environment. We incurred

net losses in each year from our inception in September 2010 through December 31, 2018, including net losses of $209.4 million
for the year ended December 31, 2018. However, while we did generate net income of $132.2 million and $89.8 million for the
year ended December 31, 2020 and 2019, respectively, it is uncertain that we will remain profitable every quarter or every year
going forward as research and development is expensive and risky. The amount of our future net losses or net income will
depend, in part, on the amount of our future expenditures offset by the amount of future product sales. Biopharmaceutical
product development is a highly speculative undertaking and involves a substantial degree of risk.

For  example,  as  of  December  31,  2020,  we  had  an  accumulated  deficit  of  $762.8  million.  The  losses  and  accumulated
deficit  were  primarily  due  to  the  substantial  investments  we  made  to  identify,  develop  or  license  our  product  candidates,
including conducting, among other things, analytical characterization, process development and manufacturing, formulation and
clinical studies and providing general and administrative support for these operations.

For example, we completed several clinical studies with our lead product, UDENYCA® (pegfilgrastim-cbqv), before the

FDA approved UDENYCA® as a biosimilar to Neulasta on November 2, 2018. We have completed several clinical studies with
CHS-1420 (our adalimumab (Humira) biosimilar candidate), which is still investigational. We also completed several clinical
studies for CHS-0214 (our etanercept (Enbrel) biosimilar candidate), which we then subsequently discontinued.

We have not yet initiated clinical trials for toripalimab or any other future products which may be developed. We anticipate

we will incur certain development and pre-commercial expenses for the Lucentis biosimilar candidate, which we licensed from
Bioeq in November 2019, and for the Avastin biosimilar candidate, which we licensed from Innovent in January 2020.

If we obtain regulatory approval to market a biosimilar product candidate, our future revenue will depend upon the size of
any  markets  in  which  our  product  candidates  may  receive  approval  and  our  ability  to  achieve  sufficient  market  acceptance,
pricing, reimbursement from third-party payers, and adequate market share for our product candidates which include all product
candidates  for  which  we  obtained  commercial  rights,  in  those  markets.  However,  even  additional  product  candidates  beyond
UDENYCA® gain regulatory approval and are commercialized, we may not remain profitable.

Our expenses will increase substantially if and as we:  

●

●

●

●

●

●

establish  a  sales,  marketing  and  distribution  infrastructure  to  commercialize  UDENYCA®  or  any  of  our  product
candidates for which we may obtain marketing approval;

make upfront, milestone, royalty or other payments under any license agreements;

continue our nonclinical and clinical development of our product candidates;

initiate additional nonclinical, clinical or other studies for our product candidates;

expand the scope of our current clinical studies for our product candidates;

advance our programs into more expensive clinical studies;

22

Table of Contents

●

●

●

●

●

●

●

●

●

change  or  add  contract  manufacturers,  clinical  research  service  providers,  testing  laboratories,  device  suppliers,
legal service providers or other vendors or suppliers;

seek regulatory and marketing approvals for our product candidates that successfully complete clinical studies;

seek  to  identify,  assess,  acquire  and/or  develop  other  biosimilar  product  candidates  or  products  that  may  be
complementary to our products;

seek to create, maintain, protect and expand our intellectual property portfolio;

engage  legal  counsel  and  technical  experts  to  help  us  evaluate  and  avoid  infringing  any  valid  and  enforceable
intellectual property rights of third parties;

engage in litigation including patent litigation and Inter Partes Review (“IPR”) proceedings with originator companies
or others that may hold patents;

seek to attract and retain skilled personnel;

create  additional  infrastructure  to  support  our  operations  as  a  public  company  and  our  product  development  and
planned future commercialization efforts; and

experience  any  delays  or  encounter  issues  with  any  of  the  above,  including  but  not  limited  to  failed  studies,
conflicting  results,  safety  issues,  manufacturing  delays,  litigation  or  regulatory  challenges  that  may  require  longer
follow-up of existing studies, additional major studies or additional supportive studies or analyses in order to pursue
marketing approval.

Further, the net loss or net income we incur may fluctuate significantly from quarter-to-quarter and year-to-year such that a

period-to-period comparison of our results of operations may not be a good indication of our future performance quarter-to-
quarter and year-to-year due to factors including the timing of clinical trials, any litigation that we may initiate or that may be
initiated against us, the execution of collaboration, licensing or other agreements and the timing of any payments we make or
receive thereunder.

We may be unable to maintain or increase profitability.

Although we reported net income of $132.2 million and $89.8 million for the years ended December 31, 2020 and 2019,
respectively, we may not be able to maintain or increase profitability, and we are unable to predict the extent of our long-range
future profits or losses. The amount of net income or net loss will depend, in part, on the level of sales of UDENYCA® in the
United  States  and  the  level  of  our  expenses  as  we  expand  our  product  pipeline.  To  offset  these  expenses,  we  will  need  to
generate substantial revenue. If expenses exceed our expectations, or if we fail to achieve expected revenue targets, the market
value of our common stock may decline.

We continue to be dependent on the ability to raise funding. This additional funding may not be available on acceptable
terms or at all. Failure to obtain this necessary capital when needed may force us to delay, limit or terminate our
product development and commercialization efforts or other operations.

As of December 31, 2020, our cash and cash equivalents were $541.2 million. We expect that our existing cash and cash
equivalents and cash collected from our UDENYCA® sales will be sufficient to fund our current operations for the foreseeable
future. We have financed our operations primarily through the sale of equity securities, convertible notes, credit facilities, license
agreements and through recent product sales of UDENYCA®.

However, our operating or investing plans may change as a result of many factors that may currently be unknown to us,
and we may need to seek additional funds sooner than planned. Our future funding requirements will depend on many factors,
including but not limited to:

●

●

●

our  ability  to  continue  to  successfully  commercialize  UDENYCA®,  and  to  compete  against  Neulasta,  Neulasta
Onpro® and new and existing commercial pegfilgrastim biosimilar products;

the scope, rate of progress, results and cost of any clinical studies, nonclinical testing and other related activities;

the cost of manufacturing clinical drug supplies and establishing commercial supplies, of our product candidates and
any products that we may develop;

23

Table of Contents

●

●

●

●

●

●

the number and characteristics of product candidates that we pursue;

the cost, timing and outcomes of regulatory approvals;

the cost and timing of establishing sales, marketing and distribution capabilities;

the  terms  and  timing  of  any  licensing  or  other  arrangements  to  acquire  intellectual  property  rights  that  we  may
establish, including any milestone and royalty payments thereunder;

the timing of conversion in common shares or repayment in cash of our convertible debt, or the timing of repayment
in cash, whether due or not, of our credit facilities; and

the cost, timing and outcomes of any litigation that we may file against third parties or that may be filed against us by
third parties.

Any additional fundraising efforts may divert our management from their day-to-day activities, which may adversely affect
our ability to develop and commercialize our product candidates. In addition, we cannot guarantee that future financing will be
available in sufficient amounts or on terms acceptable to us, if at all. Moreover, the terms of any financing may adversely affect
the  holdings  or  the  rights  of  our  stockholders,  and  the  issuance  of  additional  securities,  whether  equity  or  debt,  by  us  or  the
possibility  of  such  issuance  may  cause  the  market  price  of  our  shares  to  decline.  The  sale  of  additional  equity  or  convertible
securities  would  dilute  the  share  ownership  of  our  existing  stockholders.  The  incurrence  of  indebtedness  could  result  in
increased fixed payment obligations and we may be required to agree to certain restrictive covenants, such as limitations on our
ability to incur additional debt, limitations on our ability to acquire, sell or license intellectual property rights and other operating
restrictions  that  could  adversely  impact  our  ability  to  conduct  our  business.  We  could  also  be  required  to  seek  funds  through
arrangements  with  collaborative  partners  or  otherwise  at  an  earlier  stage  than  otherwise  would  be  desirable  and  we  may  be
required to relinquish rights to some of our technologies or product candidates or otherwise agree to terms unfavorable to us,
any of which may have a material adverse effect on our business, operating results and prospects. Even if we believe we have
sufficient funds for our current or future operating plans, we may seek additional capital if market conditions are favorable or for
specific strategic considerations.

If  we  are  unable  to  obtain  funding  on  a  timely  basis,  stay  profitable  or  increase  our  net  profits,  we  may  be  required  to
significantly curtail, delay or discontinue one or more of our research or development programs or the commercialization of any
product  candidates  or  be  unable  to  expand  our  operations  or  otherwise  capitalize  on  our  business  opportunities,  as  desired,
which could materially affect our financial condition and results of operations.

Our ability to use our net operating loss carryforwards and certain other tax attributes may be limited.

To the extent that we continue to generate taxable losses, unused losses will carry forward to offset future taxable income,
if any, until such unused losses expire. Under Sections 382 and 383 of the Internal Revenue Code of 1986, as amended, if a
corporation undergoes an “ownership change” (generally defined as a greater than 50 percentage point change (by value) in its
equity  ownership  by  certain  stockholders  over  a  rolling  three-year  period),  such  corporation’s  ability  to  use  its  pre-change  net
operating loss carryforwards (“NOLs”) and other pre-change tax attributes (such as research tax credits) to offset its post-change
income or taxes may be limited. We have experienced ownership changes in the past and may experience ownership changes
in the future (some of which changes are outside our control). As a result, if we earn net taxable income, our ability to use our
pre-change NOLs to offset such taxable income may be subject to limitations. Similar provisions of state tax law may also apply
to limit our use of accumulated state tax attributes. In addition, at the state level, there may be periods during which the use of
NOLs is suspended or otherwise limited, which could accelerate or permanently increase state taxes owed. As a result, even as
we attained profitability, we may be unable to use a material portion of our NOLs and other tax attributes, which could adversely
affect our future cash flows.

Risks Related to Launch and Commercialization of UDENYCA® and our Other Product Candidates

We have a limited operating history in an emerging regulatory environment on which to assess our business.

We  are  a  biotherapeutics  company  with  a  limited  operating  history  in  an  emerging  regulatory  environment  of  biosimilar
products.  Although  we  have  received  upfront  payments,  milestone  and  other  contingent  payments  and/or  funding  for
development from some of

24

Table of Contents

our collaboration and license agreements, UDENYCA® (pegfilgrastim-cbqv) is our only product approved for commercialization
in the United States and E.U., and we have no products approved in any other territories.

Our  ability  to  generate  meaningful  revenue  and  remain  profitable  depends  on  our  ability,  alone  or  with  strategic
collaboration  partners,  to  successfully  market  and  sell  UDENYCA®,  and  to  complete  the  development  of,  and  obtain  the
regulatory and marketing approvals necessary to commercialize, one or more of our other product pipeline candidates, which
include:

●

●

●

●

●

Toripalimab;

Bioeq’s ranibizumab (Lucentis) biosimilar candidate;

Innovent’s bevacizumab (Avastin) biosimilar candidate;

CHS-1420 (our adalimumab (Humira) biosimilar candidate); and

CHS-131 (our NASH small molecule drug candidate).

We  may  not  be  able  to  continue  to  generate  meaningful  revenue  from  product  sales,  as  this  depends  heavily  on  our

success in many areas, including but not limited to:

●

●

●

●

●

●

●

●

●

●

●

●

●

●

●

●

our ability to continue to successfully commercialize UDENYCA®;

competing against current and future pegfilgrastim products;

healthcare providers, payers, and patients adopting our product candidates once approved and launched;

our ability to procure and commercialize our in-licensed biosimilar candidates;

obtaining  additional  regulatory  and  marketing  approvals  for  product  candidates  for  which  we  complete  clinical
studies;

obtaining adequate third-party coverage and reimbursements for our products;

obtaining market acceptance of our product candidates as viable treatment options;

completing nonclinical and clinical development of our product candidates;

developing and testing of our product formulations;

attracting, hiring and retaining qualified personnel;

developing a sustainable and scalable manufacturing process for any approved product candidates and establishing
and maintaining supply and manufacturing relationships with third parties that can conduct the process and provide
adequate (in amount and quality) products to support clinical development and the market demand for our product
candidates, if approved;

addressing any competing technological and market developments;

identifying, assessing and developing (or acquiring/in-licensing) new product candidates;

negotiating favorable terms in any collaboration, licensing or other arrangements into which we may enter;

maintaining, protecting and expanding our portfolio of intellectual property rights, including patents, trade secrets and
know-how; and

defending against any litigation including patent or trade secret infringement lawsuits, that may be filed against us, or
achieving successful outcomes of IPR petitions that we have filed, or may in the future file, against third parties.

Even  if  one  or  more  of  the  product  candidates  that  we  develop  is  approved  for  commercial  sale,  we  anticipate  incurring
significant costs to commercialize any such product. Our expenses could increase beyond our expectations if we are required by
the  FDA,  the  EMA,  other  regulatory  agencies,  domestic  or  foreign,  or  by  any  unfavorable  outcomes  in  intellectual  property
litigation filed against us, to change our manufacturing processes or assays or to perform clinical, nonclinical or other types of
studies  in  addition  to  those  that  we  currently  anticipate.  In  cases  where  we  are  successful  in  obtaining  additional  regulatory
approvals to market one or more of our product candidates, our revenue will be dependent, in part, upon the size of the markets
in the territories for which we gain regulatory approval, the number of biosimilar competitors in such markets, the accepted price
for the product, the ability to get reimbursement at any price, the nature

25

Table of Contents

and  degree  of  competition  from  originators  and  other  biosimilar  companies  (including  competition  from  large  pharmaceutical
companies entering the biosimilar market that may be able to gain advantages in the sale of biosimilar products based on brand
recognition and/or existing relationships with customers and payers) and whether we own (or have partnered) the commercial
rights for that territory. If the market for our product candidates (or our share of that market) is not as significant as we expect,
the indication approved by regulatory authorities is narrower than we expect or the reasonably accepted population for treatment
is  narrowed  by  competition,  physician  choice  or  treatment  guidelines,  we  may  not  generate  significant  revenue  from  sales  of
such  products,  even  if  approved.  If  we  are  unable  to  successfully  complete  development  and  obtain  additional  regulatory
approval for our products, our business may suffer.

The commercial success of UDENYCA®, or any future product candidate, will depend upon the degree of market
acceptance and adoption by healthcare providers, patients, third-party payers and others in the medical community.

Even with the requisite approvals from the FDA and comparable foreign regulatory authorities, the commercial success of
UDENYCA®, or any of our future product candidates, if approved, will depend in part on the medical community, patients and
third-party payers accepting our product candidates as medically useful, cost-effective and safe. Any product that we bring to the
market may not gain market acceptance by physicians, patients, third-party payers and others in the medical community. The
degree  of  market  acceptance  of  any  of  our  product  candidates,  if  approved  for  commercial  sale,  will  depend  on  a  number  of
factors, including:

●

●

●

●

●

●

●

●

●

●

●

●

●

●

●

●

●

the safety and efficacy of the product as demonstrated in clinical studies and potential advantages over competing
treatments;

the  prevalence  and  severity  of  any  side  effects,  including  any  limitations  or  warnings  contained  in  a  product’s
approved labeling;

the clinical indications for which approval is granted;

the possibility that a competitor may achieve interchangeability and we may not;

relative convenience and ease of administration;

the  extent  to  which  our  product  may  be  similar  to  the  originator  product  than  competing  biosimilar  product
candidates;

policies and practices governing the naming of biosimilar product candidates;

prevalence of the disease or condition for which the product is approved;

the cost of treatment, particularly in relation to competing treatments;

the willingness of the target patient population to try new therapies and of physicians to prescribe these therapies;

the strength of marketing and distribution support and timing of market introduction of competitive products;

the extent to which the product is approved for inclusion on formularies of hospitals and managed care organizations;

publicity concerning our products or competing products and treatments;

the  extent  to  which  third-party  payers  provide  adequate  third-party  coverage  and  reimbursement  for  our  product
candidates, if approved;

the price at which we sell our products;

the actions taken by competitors to delay, restrict or block customer usage of the product; and

our ability to maintain compliance with regulatory requirements.

Market acceptance of UDENYCA®, and our other future product candidates, if approved, will not be fully known until after
it  is  launched  and  may  be  negatively  affected  by  a  potential  poor  safety  experience  and  the  track  record  of  other  biosimilar
product  candidates.  Our  efforts  to  educate  the  medical  community  and  third-party  payers  on  the  benefits  of  the  product
candidates  may  require  significant  resources,  may  be  under-resourced  compared  to  large  well-funded  pharmaceutical  entities
and  may  never  be  successful.  If  our  product  candidates  are  approved  but  fail  to  achieve  an  adequate  level  of  acceptance  by
physicians, patients, third-party payers and others in the medical community, we will not be able to generate sufficient revenue to
remain profitable.

The third-party coverage and reimbursement status of UDENYCA® (or our other product candidates, if approved) is
uncertain. Failure to obtain or maintain adequate coverage and reimbursement for new or current products could limit
our ability to market those products and decrease our ability to generate revenue.

Pricing, coverage and reimbursement of UDENYCA®, or any of our biosimilar product candidates, if approved, may not be
adequate  to  support  our  commercial  infrastructure.  Our  per-patient  prices  may  not  continue  to  be  sufficient  to  recover  our
development and manufacturing costs, and as a result, we may not be profitable in the future. Accordingly, the availability and
adequacy  of  coverage  and  reimbursement  by  governmental  and  private  payers  are  essential  for  most  patients  to  be  able  to
afford expensive treatments such as ours. Sales will depend substantially, both domestically and abroad, on the extent to which
the  costs  of  our  products  will  be  paid  for  by  health  maintenance,  managed  care,  pharmacy  benefit  and  similar  healthcare
management  organizations  or  reimbursed  by  government  authorities,  private  health  insurers  and  other  third-party  payers.  If
coverage and reimbursement are not available, or are available only to limited levels, or become unavailable, we may not be
able to successfully commercialize UDENYCA® or any of our product candidates, if approved. Even if coverage is provided, the
approved reimbursement amount may not be adequate to allow us to establish or maintain pricing sufficient to realize a return
on our investment.

There  is  significant  uncertainty  related  to  third-party  coverage  and  reimbursement  of  newly  approved  products.  In  the
United States, third-party payers, including private and governmental payers such as the Medicare and Medicaid programs, play
an  important  role  in  determining  the  extent  to  which  new  drugs  and  biologics  will  be  covered  and  reimbursed.  The  Medicare
program covers certain individuals aged 65 or older or those who are disabled or suffering from end-stage renal disease. The
Medicaid  program,  which  varies  from  state  to  state,  covers  certain  individuals  and  families  who  have  limited  financial  means.
The Medicare and Medicaid programs increasingly are used as models for how private payers and other governmental payers
develop  their  coverage  and  reimbursement  policies  for  drugs  and  biologics.  It  is  difficult  to  predict  what  third-party  payers  will
decide with respect to the coverage and reimbursement for any newly approved product. In addition, in the United States, no
uniform  policy  of  coverage  and  reimbursement  for  biologics  exists  among  third-party  payers.  Therefore,  coverage  and
reimbursement for biologics can differ significantly from payer to payer. As a result, the process for obtaining favorable coverage
determinations often is time-consuming and costly and may require us to provide scientific and clinical support for the use of our
products to each payer separately, with no assurance that coverage and adequate reimbursement will be obtained.

Effective  January  2019,  CMS  assigned  a  product  specific  Q-Code  to  UDENYCA®,  which  is  necessary  to  allow
UDENYCA® to have its own reimbursement rate and average selling price with Medicare or other third-party payers. However,
reimbursement is not guaranteed and rates may vary based on product life cycle, site of care, type of payer, coverage decisions,
and  provider  contracts.  Furthermore,  while  a  large  majority  of  payers  have  adopted  the  Q-Code  assigned  by  CMS  for
UDENYCA®, there remains uncertainty as to whether such payers will continue to cover and pay providers for the administration
and  use  of  the  product  with  each  patient  or  may  favor  a  competing  product.  If  UDENYCA®,  or  any  of  our  future  product
candidates, are not covered or adequately reimbursed by third-party payers, including Medicare, then the cost of the relevant
product may be absorbed by healthcare providers or charged to patients. If this is the case, our expectations of the pricing we
expect to achieve for such product and the related potential revenue, may be significantly diminished.

Outside  the  U.S.,  pharmaceutical  businesses  are  generally  subject  to  extensive  governmental  price  controls  and  other
market regulations. We believe the increasing emphasis on cost-containment initiatives in Europe, Canada and other countries
has  and  will  continue  to  put  pressure  on  the  pricing  and  usage  of  our  product  candidates.  In  many  countries,  the  prices  of
medical  products  are  subject  to  varying  price  control  mechanisms  as  part  of  national  health  systems.  Other  countries  allow
companies to fix their own prices for medical products, but monitor and control company profits. Additional foreign price controls
or  other  changes  in  pricing  regulation  could  restrict  the  amount  that  we  are  able  to  charge  for  our  product  candidates.
Accordingly, in markets outside the U.S., the reimbursement for our products may be reduced compared with the U.S. and may
be insufficient to generate commercially reasonable revenue and profits.

Increasing efforts by governmental and third-party payers in the United States and abroad to control healthcare costs may
cause such organizations to limit both coverage and the level of reimbursement for new products approved and, as a result, they
may not cover or provide adequate payment for UDENYCA® or any of our product candidates. While cost containment practices
generally  benefit  biosimilars,  severe  cost  containment  practices  may  adversely  affect  our  product  sales.  We  expect  to
experience  pricing  pressures  in  connection  with  the  sale  of  UDENYCA®  and  any  of  our  product  candidates  due  to  the  trend
toward managed healthcare, the increasing influence of health maintenance organizations and additional legislative changes.

27

UDENYCA® and our other product candidates, even if approved, will remain subject to regulatory scrutiny.

If our product candidates are approved, they will be subject to ongoing regulatory requirements for manufacturing, labeling,
packaging,  storage,  advertising,  promotion,  sampling,  record-keeping,  conduct  of  post-marketing  studies  and  submission  of
safety,  efficacy  and  other  post-market  information,  including  both  federal  and  state  requirements  in  the  United  States  and
requirements of comparable foreign regulatory authorities.

Manufacturers and manufacturers’ facilities are required to comply with extensive FDA, and comparable foreign regulatory
authority,  requirements,  including  ensuring  that  quality  control  and  manufacturing  procedures  conform  to  current  Good
Manufacturing Practices (“cGMP”), regulations. As such, we and our contract manufacturers will be subject to continual review
and inspections to assess compliance with cGMP and adherence to commitments made in any NDA, original BLA, 351(k) BLA
or  MAA.  Accordingly,  we  and  others  with  whom  we  work  must  continue  to  expend  time,  money  and  effort  in  all  areas  of
regulatory compliance, including manufacturing, production and quality control.

Any  regulatory  approvals  that  we  or  our  collaboration  partners  receive  for  our  product  candidates  may  be  subject  to
limitations  on  the  approved  indicated  uses  for  which  the  product  may  be  marketed  or  to  the  conditions  of  approval  or  may
contain  requirements  for  potentially  costly  additional  clinical  trials  and  surveillance  to  monitor  the  safety  and  efficacy  of  the
product  candidate.  We  will  be  required  to  report  certain  adverse  events  and  production  problems,  if  any,  to  the  FDA  and
comparable  foreign  regulatory  authorities.  Any  new  legislation  addressing  drug  safety  issues  could  result  in  delays  in  product
development  or  commercialization  or  increased  costs  to  assure  compliance.  We  will  have  to  comply  with  requirements
concerning  advertising  and  promotion  for  our  products.  Promotional  communications  with  respect  to  prescription  drugs  are
subject  to  a  variety  of  legal  and  regulatory  restrictions  and  must  be  consistent  with  the  information  in  the  product’s  approved
label.  As  such,  we  may  not  promote  our  products  for  indications  or  uses  for  which  they  do  not  have  approval.  If  our  product
candidates  are  approved,  we  must  submit  new  or  supplemental  applications  and  obtain  approval  for  certain  changes  to  the
approved products, product labeling or manufacturing process. We or our collaboration partners could also be asked to conduct
post-marketing clinical studies to verify the safety and efficacy of our products in general or in specific patient subsets. If original
marketing  approval  is  obtained  via  an  accelerated  biosimilar  approval  pathway,  we  could  be  required  to  conduct  a  successful
post-marketing  clinical  study  to  confirm  clinical  benefit  for  our  products.  An  unsuccessful  post-marketing  study  or  failure  to
complete such a study could result in the withdrawal of marketing approval.

If  a  regulatory  agency  discovers  previously  unknown  problems  with  a  product,  such  as  adverse  events  of  unanticipated
severity or frequency or problems with the facility where the product is manufactured or disagrees with the promotion, marketing
or labeling of a product, such regulatory agency may impose restrictions on that product or us, including requiring withdrawal of
the product from the market. If we fail to comply with applicable regulatory requirements, a regulatory agency or enforcement
authority may, among other possibilities:

●

●

●

●

●

●

●

issue warning letters;

impose civil or criminal penalties;

suspend or withdraw regulatory approval;

suspend any of our ongoing clinical studies;

refuse to approve pending applications or supplements to approved applications submitted by us;

impose restrictions on our operations, including closing our contract manufacturers’ facilities; or

seize or detain products or require a product recall.

Any  government  investigation  of  alleged  violations  of  law  could  require  us  to  expend  significant  time  and  resources  in
response  and  could  generate  negative  publicity.  Any  failure  to  comply  with  ongoing  regulatory  requirements  may  significantly
and adversely affect our ability to commercialize and generate revenue from our products. If regulatory sanctions are applied or
if regulatory approval is withdrawn, the value of our company and our operating results will be adversely affected.

The FDA’s and other regulatory authorities’ policies may change and additional government regulations may be enacted
that could prevent, limit or delay regulatory approval of our product candidates. If we are slow or unable to adapt to changes in
existing requirements or the adoption of new requirements or policies, or if we are not able to maintain regulatory compliance,
we may lose any marketing

28

Table of Contents

approval that we may have obtained and we may not sustain profitability, which would adversely affect our business, prospects,
financial condition and results of operations.

We also cannot predict the likelihood, nature or extent of government regulation that may arise from future legislation or
administrative or executive action, either in the United States or abroad. For example, the results of the 2020 U.S. Presidential
Election may impact our business and industry. Namely, the Trump administration took several executive actions, including the
issuance  of  a  number  of  executive  orders,  that  could  impose  significant  burdens  on,  or  otherwise  materially  delay,  the  FDA’s
ability  to  engage  in  routine  regulatory  and  oversight  activities  such  as  implementing  statutes  through  rulemaking,  issuance  of
guidance, and review and approval of marketing applications. It is difficult to predict whether or how these executive actions will
be implemented, or whether they will be rescinded and replaced under the Biden administration. The policies and priorities of a
new administration are unknown and could materially impact the regulations governing our product candidates.

Disruptions at the FDA and other government agencies caused by funding shortages or global health concerns could
hinder their ability to hire, retain or deploy key leadership and other personnel, or otherwise prevent new or modified
products  from  being  developed,  or  approved  or  commercialized  in  a  timely  manner  or  at  all,  which  could  negatively
impact our business.

The ability of the FDA to review and approve new products can be affected by a variety of factors, including government
budget  and  funding  levels,  statutory,  regulatory,  and  policy  changes,  the  FDA’s  ability  to  hire  and  retain  key  personnel  and
accept  the  payment  of  user  fees,  and  other  events  that  may  otherwise  affect  the  FDA’s  ability  to  perform  routine  functions.
Average  review  times  at  the  FDA  have  fluctuated  in  recent  years  as  a  result.  In  addition,  government  funding  of  other
government agencies that fund research and development activities is subject to the political process, which is inherently fluid
and  unpredictable.  Disruptions  at  the  FDA  and  other  agencies  may  also  slow  the  time  necessary  for  new  biologics  or
modifications to approved biologics to be reviewed and/or approved by necessary government agencies, which would adversely
affect our business. For example, over the last several years, including for 35 days beginning on December 22, 2018, the U.S.
government  has  shut  down  several  times  and  certain  regulatory  agencies,  such  as  the  FDA,  have  had  to  furlough
critical FDA employees and stop critical activities.  

Separately, in response to the COVID-19 pandemic, on March 10, 2020 the FDA announced its intention to postpone most
foreign  inspections  of  manufacturing  facilities  and  products  through  April  2020,  and  on  March  18,  2020,  the  FDA  temporarily
postponed  routine  surveillance  inspections  of  domestic  manufacturing  facilities.  Subsequently,  on  July  10,  2020,  the  FDA
announced  its  intention  to  resume  certain  on-site  inspections  of  domestic  manufacturing  facilities  subject  to  a  risk-based
prioritization system. The FDA intends to use this risk-based assessment system to identify the categories of regulatory activity
that can occur within a given geographic area, ranging from mission critical inspections to resumption of all regulatory activities.
Regulatory  authorities  outside  the  United  States  may  adopt  similar  restrictions  or  other  policy  measures  in  response  to  the
COVID-19 pandemic. If a prolonged government shutdown occurs, or if global health concerns continue to prevent the FDA or
other regulatory authorities from conducting their regular inspections, reviews, or other regulatory activities, it could significantly
impact the ability of the FDA or other regulatory authorities to timely review and process our regulatory submissions, which could
have a material adverse effect on our business.

Risks Related to Competitive Activity

UDENYCA®, or our other biosimilar product candidates, if approved, will face significant competition from the
reference products and from other biosimilar products or pharmaceuticals approved for the same indication as the
originator products. Our failure to effectively compete may prevent us from achieving significant market penetration
and expansion.

We  operate  in  highly  competitive  pharmaceutical  markets.  Successful  competitors  in  the  pharmaceutical  market  have
demonstrated  the  ability  to  effectively  discover,  obtain  patents,  develop,  test  and  obtain  regulatory  approvals  for  products,  as
well as an ability to effectively commercialize, market and promote approved products. Numerous companies, universities and
other  research  institutions  are  engaged  in  developing,  patenting,  manufacturing  and  marketing  of  products  competitive  with
those  that  we  are  developing.  Many  of  these  potential  competitors  are  large,  experienced  multinational  pharmaceutical  and
biotechnology  companies  that  enjoy  significant  competitive  advantages,  such  as  substantially  greater  financial,  research  and
development, manufacturing, personnel, marketing resources, and the benefits of mergers and acquisitions.

Specifically,  some  of  the  pharmaceutical  and  biotechnology  companies  we  expect  to  compete  with  include:  Sandoz
International GmbH (“Sandoz”), Amgen Inc. (“Amgen”), Pfizer Inc., Boehringer Ingelheim GmbH (“Boehringer Ingelheim”), Teva
Pharmaceutical Industries, Ltd. (“Teva”), and Samsung Bioepis, Ltd. (“Samsung Bioepis”), (a Merck/Biogen/Samsung biosimilar
venture), Mylan N.V.

29

Table of Contents

(“Mylan”), and Cinfa Biotech S.L. (“Cinfa,” a subsidiary of Mundipharma), as well as other smaller companies. We are currently
aware  that  such  competitors  are  engaged  in  the  development  and  commercialization  of  biosimilar  product  candidates  to
pegfilgrastim (Neulasta), ranibizumab (Lucentis), bevacizumab (Avastin), adalimumab (Humira) and aflibercept (Eylea).

UDENYCA®  faces  competition  in  the  United  States  from  Amgen,  Mylan  (with  partner  Biocon  Ltd.),  Sandoz,  Pfizer,  and

may face completion from Amneal and Fresenius, companies that announced the development of a pegfilgrastim biosimilar.

Our  ranibizumab  (Lucentis)  biosimilar  candidate  licensed  from  Bioeq  may  face  competition  in  the  United  States  from
Genentech  (the  manufacturer  of  Lucentis).  Biogen  Inc.  (“Biogen”)  with  collaborator  Samsung  Bioepis  Co.,  Ltd.  (Samsung
Bioepis), and Xbrane Biopharma AB (in collaboration with STADA Arzneimittel AG and Bausch + Lomb) have each disclosed the
development for a Lucentis biosimilar candidate.

Our  bevacizumab  (Avastin)  biosimilar  candidate  licensed  from  Innovent  may  face  competition  in  the  United  States  from
Genentech (the manufacturer of Avastin) as well as Amgen and Pfizer, each of which have initiated the commercial launch of an
Avastin biosimilar.

Similarly, CHS-1420, our adalimumab (Humira) biosimilar may face competition from AbbVie (the manufacturer of Humira)
as  well  as  manufacturers  of  Humira  biosimilars  such  as  Pfizer,  Boehringer  Ingelheim,  Amgen,  Sandoz  and  Samsung  Bioepis.
There  are  five  adalimumab  biosimilar  products  FDA-approved  in  the  United  States  and  Fujifilm  and  Fresenius  are  companies
that have each disclosed development plans for a Humira biosimilar candidate. As a result of number of potential adalimumab
(Humira) biosimilar competitors, we may not be able to achieve substantial topline sales for CHS-1420 in the United States, if
approved.

These  companies  may  also  have  greater  brand  recognition  and  more  experience  in  conducting  preclinical  testing  and
clinical  trials  of  product  candidates,  obtaining  FDA  and  other  regulatory  approvals  of  products  and  marketing  and
commercializing products once approved.

Additionally,  many  manufacturers  of  originator  products  have  increasingly  used  legislative,  regulatory  and  other  means,
such  as  litigation,  to  delay  regulatory  approval  and  to  seek  to  restrict  competition  from  manufacturers  of  biosimilars.  These
efforts may include or have included:  

●

●

●

●

●

●

●

●

●

●

●

settling,  or  refusing  to  settle,  patent  lawsuits  with  biosimilar  companies,  resulting  in  such  patents  remaining  an
obstacle for biosimilar approval;

submitting  Citizen  Petitions  to  request  the  FDA  Commissioner  to  take  administrative  action  with  respect  to
prospective and submitted biosimilar applications;

appealing denials of Citizen Petitions in U.S. federal district courts and seeking injunctive relief to reverse approval of
biosimilar applications;

restricting  access  to  reference  brand  products  for  equivalence  and  biosimilarity  testing  that  interferes  with  timely
biosimilar development plans;

attempting to influence potential market share by conducting medical education with physicians, payers, regulators
and  patients  claiming  that  biosimilar  products  are  too  complex  for  biosimilar  approval  or  are  too  dissimilar  from
originator products to be trusted as safe and effective alternatives;

implementing payer market access tactics that benefit their brands at the expense of biosimilars;

seeking state law restrictions on the substitution of biosimilar products at the pharmacy without the intervention of a
physician or through other restrictive means such as excessive recordkeeping requirements or patient and physician
notification;

seeking federal or state regulatory restrictions on the use of the same non-proprietary name as the reference brand
product for a biosimilar or interchangeable biologic;

seeking changes to the U.S. Pharmacopeia, an industry recognized compilation of drug and biologic standards;

obtaining new patents covering existing products or processes, which could extend patent exclusivity for a number of
years or otherwise delay the launch of biosimilars; and

influencing legislatures so that they attach special patent extension amendments to unrelated federal legislation.

30

Table of Contents

UDENYCA® and our other biosimilar product candidates, if approved, could face price competition from other
biosimilars of the same reference products for the same indication. This price competition could exceed our capacity
to respond, detrimentally affecting our market share and revenue as well as adversely affecting the overall financial
health and attractiveness of the market for the biosimilar.

Competitors  in  the  biosimilar  market  have  the  ability  to  compete  on  price  with  healthcare  providers,  and  through  payers
and  their  third-party  administrators,  who  exert  downward  pricing  pressure  on  our  price  offerings.  It  is  possible  our  biosimilar
competitors’  compliance  with  price  discounting  demands  in  exchange  for  market  share  or  volume  requirements  could  exceed
our  capacity  to  respond  in  kind  and  reduce  market  prices  beyond  our  expectations.  Such  practices  may  limit  our  ability  to
increase market share and may also impact profitability.

We face intense competition and rapid technological change and the possibility that our competitors may develop
therapies that are similar, more advanced or more effective than ours, which may adversely affect our financial
condition and our ability to successfully commercialize our product candidates.

Many of our competitors have substantially greater financial, technical and other resources, such as larger research and
development  staff  and  experienced  marketing  and  manufacturing  organizations.  Additional  mergers  and  acquisitions  in  the
pharmaceutical industry may result in even more resources being concentrated in our competitors. As a result, these companies
may  obtain  regulatory  approval  more  rapidly  than  we  are  able  to  and  may  be  more  effective  in  selling  and  marketing  their
products.  Smaller  or  early-stage  companies  may  also  prove  to  be  significant  competitors,  particularly  through  collaborative
arrangements  with  large,  established  companies.  Our  competitors  may  succeed  in  developing,  acquiring  or  licensing  on  an
exclusive basis, products that are more effective or less costly than any product candidate that we may develop; they may also
obtain patent protection that could block our products; and they may obtain regulatory approval, product commercialization and
market  penetration  earlier  than  we  do.  Biosimilar  product  candidates  developed  by  our  competitors  may  render  our  potential
product  candidates  uneconomical,  less  desirable  or  obsolete,  and  we  may  not  be  successful  in  marketing  our  product
candidates against competitors.

If other biosimilars of bevacizumab (Avastin), ranibizumab (Lucentis), aflibercept (Eylea) or adalimumab (Humira), are
approved and successfully commercialized before our product candidates for these originator products, our business
would suffer.

We expect other companies to seek approval to manufacture and market biosimilar versions of Avastin, Lucentis, Eylea or
Humira.  If  other  biosimilars  of  these  branded  biologics  are  approved  and  successfully  commercialized  before  our  biosimilar
candidates, we may never achieve meaningful market share for these products, our revenue would be reduced and, as a result,
our  business,  prospects  and  financial  condition  could  suffer.  For  instance,  Mylan  received  FDA  approval  for  its  pegfilgrastim
biosimilar  in  June  2018,  and  in  July  2018,  Mylan  initiated  the  commercialization  in  the  United  States  of  this  biosimilar.
Furthermore,  in  September  2018,  the  EC  granted  marketing  authorization  to  UDENYCA®  and  to  a  pegfilgrastim  biosimilar
candidate  from  Intas.  In  November  and  December  2018,  the  EC  granted  marketing  authorizations  to  three  additional
pegfilgrastim biosimilar candidates from Sandoz, Mylan and Cinfa. In June 2019, the E.U. granted marketing authorization to a
pegfilgrastim biosimilar candidate from USV Biologics.

If an improved version of an originator product, such as Neulasta, Humira, Lucentis or Eylea, is developed or if the
market for the originator product significantly declines, sales or potential sales of our biosimilar product candidates
may suffer.

Originator companies may develop improved versions of a reference product as part of a life cycle extension strategy and
may obtain regulatory approval of the improved version under a new or supplemental BLA submitted to the applicable regulatory
authority.  Should  the  originator  company  succeed  in  obtaining  an  approval  of  an  improved  biologic  product,  it  may  capture  a
significant share of the collective reference product market in the applicable jurisdiction and significantly reduce the market for
the  reference  product  and  thereby  the  potential  size  of  the  market  for  our  biosimilar  product  candidates.  In  addition,  the
improved  product  may  be  protected  by  additional  patent  rights  that  may  subject  our  follow-on  biosimilar  to  claims  of
infringement.

Biologic reference products may also face competition as technological advances are made that may offer patients a more
convenient form of administration or increased efficacy or as new products are introduced. As new products are approved that
compete  with  the  reference  product  to  our  biosimilar  product  candidates,  sales  of  the  reference  originator  product  may  be
adversely impacted or rendered obsolete. If the market for the reference product is impacted, we may lose significant market
share  or  experience  limited  market  potential  for  our  approved  biosimilar  products  or  product  candidates,  and  the  value  of  our
product pipeline could be negatively impacted. As a result of the above factors, our business, prospects and financial condition
could suffer.

Risks Related to Our Ability to Hire and Retain Highly Qualified Personnel

We are highly dependent on the services of our key executives and personnel, including our President and Chief
Executive Officer, Dennis M. Lanfear, and if we are not able to retain these members of our management or recruit
additional management, clinical and scientific personnel, our business will suffer.

We  are  highly  dependent  on  the  principal  members  of  our  management  and  scientific  and  technical  staff.  The  loss  of
service of any of our management or key scientific and technical staff could harm our business. In addition, we are dependent
on our continued ability to attract, retain and motivate highly qualified additional management, clinical and scientific personnel. If
we are not able to retain our management, particularly our President and Chief Executive Officer, Mr. Lanfear, and to attract, on
acceptable terms, additional qualified personnel necessary for the continued development of our business, we may not be able
to sustain our operations or grow.

Our future performance will also depend, in part, on our ability to successfully integrate newly hired executive officers into
our  management  team  and  our  ability  to  develop  an  effective  working  relationship  among  senior  management.  Our  failure  to
integrate  these  individuals  and  create  effective  working  relationships  among  them  and  other  members  of  management  could
result in inefficiencies in the development and commercialization of our product candidates, harming future regulatory approvals,
sales  of  our  product  candidates  and  our  results  of  operations.  Additionally,  we  do  not  currently  maintain  “key  person”  life
insurance on the lives of our executives or any of our employees.

We  will  need  to  expand  and  effectively  manage  our  managerial,  scientific,  operational,  financial,  commercial  and  other
resources in order to successfully pursue our clinical development and commercialization efforts. Our success also depends on
our continued ability to attract, retain and motivate highly qualified management and scientific personnel. We may not be able to
attract  or  retain  qualified  management  and  scientific  and  clinical  personnel  in  the  future  due  to  the  intense  competition  for
qualified personnel among biotechnology, pharmaceutical and other businesses, particularly in the San Francisco Bay Area. If
we are not able to attract, retain and motivate necessary personnel to accomplish our business objectives, we may experience
constraints that will significantly impede the achievement of our development objectives, our ability to raise additional capital and
our ability to implement our business strategy.

We will need to expand our organization and we may experience difficulties in managing this growth, which could
disrupt our operations.

As  of  December  31,  2020,  we  had  317  employees.  As  our  development  and  commercialization  plans  and  strategies
develop,  we  expect  to  need  additional  managerial,  operational,  sales,  marketing,  financial,  legal  and  other  resources.  Our
management  may  need  to  divert  a  disproportionate  amount  of  its  attention  away  from  our  day-to-day  activities  and  devote  a
substantial amount of time to managing these growth activities. We may not be able to effectively manage the expansion of our
operations, which may result in weaknesses in our infrastructure, operational mistakes, loss of business opportunities, loss of
employees  and  reduced  productivity  among  remaining  employees.  Our  expected  growth  could  require  significant  capital
expenditures and may divert financial resources from other projects, such as the development of our current and potential future
product  candidates.  If  our  management  is  unable  to  effectively  manage  our  growth,  our  expenses  may  increase  more  than
expected,  our  ability  to  generate  and/or  grow  revenue  could  be  reduced  and  we  may  not  be  able  to  implement  our  business
strategy.  Our  future  financial  performance  and  our  ability  to  commercialize  product  candidates  and  compete  effectively  will
depend, in part, on our ability to effectively manage any future growth.

Risks Related to Reliance on Third-Party Vendors

We rely on third parties to conduct our nonclinical and clinical studies and perform other tasks for us. If these third
parties do not successfully carry out their contractual duties, meet expected deadlines or comply with regulatory
requirements, we may not be able to obtain regulatory approval for or commercialize our product candidates and our
business could be substantially harmed.

We  have  relied  upon  and  plan  to  continue  to  rely  upon  third-party  CROs  to  monitor  and  manage  data  for  our  ongoing
nonclinical and clinical programs. We rely on these parties for execution of our nonclinical and clinical studies and control only
certain  aspects  of  their  activities.  Nevertheless,  we  are  responsible  for  ensuring  that  each  of  our  studies  is  conducted  in
accordance with the applicable protocol, legal, regulatory and scientific standards and our reliance on the CROs does not relieve
us  of  our  regulatory  responsibilities.  We  and  our  CROs  and  other  vendors  are  required  to  comply  with  cGMP,  good  clinical
practices  (“GCP”),  and  Good  Laboratory  Practices  (“GLP”),  which  are  regulations  and  guidelines  enforced  by  the  FDA,  the
Competent Authorities of the Member States of the EEA and comparable foreign

32

Table of Contents

regulatory authorities for all of our product candidates in clinical development. Regulatory authorities enforce these regulations
through periodic inspections of study sponsors, principal investigators, study sites and other contractors. If we, any of our CROs,
service providers or investigators fail to comply with applicable regulations or GCPs, the data generated in our nonclinical and
clinical  studies  may  be  deemed  unreliable  and  the  FDA,  EMA  or  comparable  foreign  regulatory  authorities  may  require  us  to
perform additional nonclinical and clinical studies before approving our marketing applications. We cannot assure you that upon
inspection  by  a  given  regulatory  authority,  such  regulatory  authority  will  determine  that  any  of  our  clinical  studies  comply  with
GCP regulations. In addition, our clinical studies must be conducted with product generated under cGMP regulations. Failure to
comply  by  any  of  the  participating  parties  or  ourselves  with  these  regulations  may  require  us  to  repeat  clinical  studies,  which
would delay the regulatory approval process. Moreover, our business may be implicated if our CRO or any other participating
parties violate federal or state fraud and abuse or false claims laws and regulations or healthcare privacy and security laws.

If  any  of  our  relationships  with  these  third-party  CROs  terminate,  we  may  not  be  able  to  enter  into  arrangements  with
alternative  CROs  or  do  so  on  commercially  reasonable  terms.  In  addition,  our  CROs  are  not  our  employees,  and  except  for
remedies available to us under our agreements with such CROs, we cannot control whether or not they devote sufficient time
and resources to our on-going nonclinical and clinical programs. If CROs do not successfully carry out their contractual duties or
obligations  or  meet  expected  deadlines,  if  they  need  to  be  replaced  or  if  the  quality  or  accuracy  of  the  data  they  obtain  is
compromised due to the failure to adhere to our protocols, regulatory requirements or for other reasons, our clinical studies may
be extended, delayed or terminated and we may not be able to obtain regulatory approval for or successfully commercialize our
product  candidates.  CROs  may  also  generate  higher  costs  than  anticipated.  As  a  result,  our  results  of  operations  and  the
commercial prospects for our product candidates would be harmed, our costs could increase and our ability to generate revenue
could be delayed.

Switching  or  adding  additional  CROs  involves  additional  cost  and  requires  management  time  and  focus.  In  addition,  a
transition period is necessary when a new CRO commences work, which can materially impact our ability to meet our desired
clinical  development  timelines.  Though  we  strive  to  carefully  manage  our  relationships  with  our  CROs,  there  can  be  no
assurance that we will not encounter similar challenges or delays in the future or that these delays or challenges will not have a
material adverse impact on our business, prospects and financial condition.

We rely on third parties, and in some cases a single third party, to manufacture nonclinical, clinical and commercial
drug supplies of our product candidates and to store critical components of our product candidates for us. Our
business could be harmed if those third parties fail to provide us with sufficient quantities of product candidates or fail
to do so at acceptable quality levels or prices.

We do not currently have the infrastructure or capability internally to manufacture supplies of our product candidates for
use  in  our  nonclinical  and  clinical  studies,  and  we  lack  the  resources  and  the  capability  to  manufacture  any  of  our  product
candidates  on  a  clinical  or  commercial  scale.  We  rely  on  third  party  manufacturers  to  manufacture  and  supply  us  with  our
product candidates for our preclinical and clinical studies as well as to establish commercial supplies of our product candidates.
Successfully  transferring  complicated  manufacturing  techniques  to  contract  manufacturing  organizations  and  scaling  up  these
techniques for commercial quantities is time consuming and we may not be able to achieve such transfer or do so in a timely
manner. Moreover, the availability of contract manufacturing services for protein-based therapeutics is highly variable and there
are  periods  of  relatively  abundant  capacity  alternating  with  periods  in  which  there  is  little  available  capacity.  If  our  need  for
contract manufacturing services increases during a period of industry-wide production capacity shortage, we may not be able to
produce  our  product  candidates  on  a  timely  basis  or  on  commercially  viable  terms.  Although  we  will  plan  accordingly  and
generally do not begin a clinical study unless we believe we have a sufficient supply of a product candidate to complete such
study, any significant delay or discontinuation in the supply of a product candidate for an ongoing clinical study due to the need
to replace a third-party manufacturer could considerably delay completion of our clinical studies, product testing and potential
regulatory approval of our product candidates, which could harm our business and results of operations.

Reliance on third-party manufacturers entails additional risks, including reliance on the third party for regulatory compliance
and quality assurance, the possible breach of the manufacturing agreement by the third party and the possible termination or
nonrenewal  of  the  agreement  by  the  third  party  at  a  time  that  is  costly  or  inconvenient  for  us.  In  addition,  third  party
manufacturers may not be able to comply with cGMP or similar regulatory requirements outside the U.S. Our failure or the failure
of our third party manufacturers to comply with applicable regulations could result in sanctions being imposed on us, including
fines,  injunctions,  civil  penalties,  delays,  suspension  or  withdrawal  of  approvals,  license  revocation,  seizures  or  recalls  of
products, operating restrictions and criminal prosecutions, any of which could significantly and adversely affect supplies of our
product  candidates  or  any  other  product  candidates  or  products  that  we  may  develop.  Any  failure  or  refusal  to  supply  the
components  for  our  product  candidates  that  we  may  develop  could  delay,  prevent  or  impair  our  clinical  development  or
commercialization efforts. If our contract manufacturers were to breach or terminate their manufacturing

33

Table of Contents

arrangements with us, the development or commercialization of the affected products or product candidates could be delayed,
which could have an adverse effect on our business. Any change in our manufacturers could be costly because the commercial
terms  of  any  new  arrangement  could  be  less  favorable  and  because  the  expenses  relating  to  the  transfer  of  necessary
technology and processes could be significant.

If  any  of  our  product  candidates  are  approved,  in  order  to  produce  the  quantities  necessary  to  meet  anticipated  market
demand, any contract manufacturer that we engage may need to increase manufacturing capacity. If we are unable to build and
stock  our  product  candidates  in  sufficient  quantities  to  meet  the  requirements  for  the  launch  of  these  candidates  or  to  meet
future  demand,  our  revenue  and  gross  margins  could  be  adversely  affected.  Although  we  believe  that  we  will  not  have  any
material  supply  issues,  we  cannot  be  certain  that  we  will  be  able  to  obtain  long-term  supply  arrangements  for  our  product
candidates  or  materials  used  to  produce  them  on  acceptable  terms,  if  at  all.  If  we  are  unable  to  arrange  for  third-party
manufacturing,  or  to  do  so  on  commercially  reasonable  terms,  we  may  not  be  able  to  complete  development  of  our  product
candidates or market them.

We  are  dependent  on  Bioeq,  Innovent  and  Orox  for  the  commercialization  of  our  biosimilar  product  candidates  in
certain  markets  and  we  intend  to  seek  additional  commercialization  partners  for  major  markets,  and  the  failure  to
commercialize in those markets could have a material adverse effect on our business and operating results.

We have an exclusive license from Bioeq to commercialize Bioeq’s ranibizumab (Lucentis) biosimilar in the United States.
We have an exclusive license from Innovent to develop and commercialize Innovent’s bevacizumab (Avastin) biosimilar in the
United States and Canada. Our licensors are responsible for supplying us with drug substance and final drug products as well
as, in the case of Innovent, the necessary regulatory data to submit a 351(k) BLA for Innovent’s bevacizumab candidate in the
United States and Canada.  

Our  exclusive  licensee,  Orox,  is  responsible  for  commercialization  of  certain  of  our  products  and  product  candidates,
including UDENYCA® and CHS-1420, in certain Caribbean and Latin American countries (excluding Brazil, and in the case of
UDENYCA®,  also  excluding  Argentina).  We  intend  to  seek  commercialization  partners  for  all  products  in  Europe  and  other
jurisdictions outside the U.S. (excluding certain Caribbean and Latin American countries).

Our  licenses  with  Bioeq,  Innovent,  Orox,  or  other  future  license  or  collaboration  agreements,  may  not  be  successful.

Factors that may affect the success of our licenses and collaborations include, but are not limited to, the following:

●

●

●

●

●

●

our existing and potential collaboration partners may fail to provide sufficient amounts of commercial products or they
may be ineffective in doing so;

our  existing  and  potential  collaboration  partners  may  fail  regulatory  inspections  which  may  preclude  or  delay  the
delivery of commercial products;

our existing and potential collaboration partners may fail to exercise commercially reasonable efforts to market and
sell our products in their respective licensed jurisdictions or they may be ineffective in doing so;

our existing and potential licensees and collaboration partners may incur financial, legal or other difficulties that force
them to limit or reduce their participation in our joint projects;

our existing and potential licensees and collaboration partners may terminate their licenses or collaborations with us,
which could make it difficult for us to attract new partners and/or adversely affect perception of us in the business and
financial communities; and

our  existing  and  potential  licensees  and  collaboration  partners  may  choose  to  pursue  alternative,  higher  priority
programs, which could affect their commitment to us.

Moreover,  any  disputes  with  our  licensees  and  collaboration  partners  will  substantially  divert  the  attention  of  our  senior
management from other business activities and will require us to incur substantial costs associated with litigation or arbitration
proceedings.  If  we  cannot  maintain  successful  license  and  collaboration  arrangements,  our  business,  financial  condition  and
operating results may be adversely affected.

Risks Related to Manufacturing and Supply Chain

We are subject to a multitude of manufacturing risks. Any adverse developments affecting the manufacturing
operations of our biosimilar product candidates could substantially increase our costs and limit supply for our product
candidates.

The process of manufacturing our product candidates is complex, highly regulated and subject to several risks, including

but not limited to:

●

●

product loss due to contamination, equipment failure or improper installation or operation of equipment or vendor or
operator error; and

equipment failures, labor shortages, natural disasters, power failures and numerous other factors associated with the
manufacturing  facilities  in  which  our  product  candidates  are  produced,  and  potentially  exacerbated  by  climate
change.

Even  minor  deviations  from  normal  manufacturing  processes  for  any  of  our  product  candidates  could  result  in  reduced
production yields, product defects and other supply disruptions. For example, we have experienced failures with respect to the
manufacturing  of  certain  lots  of  each  of  our  product  candidates  resulting  in  delays  prior  to  our  taking  corrective  action.
Additionally, 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.

Any adverse developments affecting manufacturing operations for our product candidates, including due to sudden or long-
term changes in weather patterns, may result in shipment delays, inventory shortages, lot failures, withdrawals or recalls or other
interruptions in the supply of our product candidates. We may also have to take inventory write-offs and incur other charges and
expenses  for  product  candidates  that  fail  to  meet  specifications,  undertake  costly  remediation  efforts  or  seek  costlier
manufacturing alternatives.

We currently engage single suppliers for manufacture, clinical trial services, formulation development and product
testing of our product candidates. The loss of any of these suppliers or vendors could materially and adversely affect
our business.

For  UDENYCA®  and  our  product  candidates,  we  currently  engage  a  distinct  vendor  or  service  provider  for  each  of  the
principal  activities  supporting  our  manufacture  and  development  of  these  products,  such  as  manufacture  of  the  biological
substance present in each of the products, manufacture of the final filled and finished presentation of these products, as well as
laboratory testing, formulation development and clinical testing of these products. For example, in December 2015, we entered
into  a  strategic  manufacturing  agreement  with  KBI  Biopharma,  Inc.  for  long-term  commercial  manufacturing  of  UDENYCA®.
Because we currently have engaged a limited number of back-up suppliers or vendors for these single-sourced services, and
although we believe that there are alternate sources that could fulfill these activities, we cannot assure you that identifying and
establishing  relationships  with  alternate  suppliers  and  vendors  would  not  result  in  significant  delay  in  the  development  of  our
product  candidates.  Additionally,  we  may  not  be  able  to  enter  into  arrangements  with  alternative  service  providers  on
commercially reasonable terms or at all. A delay in the development of our product candidates, or having to enter into a new
agreement  with  a  different  third  party  on  less  favorable  terms  than  we  have  with  our  current  suppliers,  could  have  a  material
adverse impact on our business.

We and our collaboration partners and contract manufacturers are subject to significant regulation with respect to
manufacturing our product candidates. The manufacturing facilities on which we rely may not continue to meet
regulatory requirements or may not be able to meet supply demands.

All entities involved in the preparation of therapeutics for clinical studies or commercial sale, including our existing contract
manufacturers  for  our  product  candidates,  are  subject  to  extensive  regulation.  Components  of  a  finished  therapeutic  product
approved  for  commercial  sale  or  used  in  clinical  studies  must  be  manufactured  in  accordance  with  cGMP.  These  regulations
govern  manufacturing  processes  and  procedures  (including  record  keeping)  and  the  implementation  and  operation  of  quality
systems to control and assure the quality of investigational products and products approved for sale. Poor control of production
processes  can  lead  to  the  introduction  of  contaminants  or  to  inadvertent  changes  in  the  properties  or  stability  of  our  product
candidates that may not be detectable in final product testing. We, our collaboration partners or our contract manufacturers must
supply all necessary documentation in support of a 351(k) BLA, original BLA, NDA or MAA on a timely basis and must adhere to
GLP and cGMP regulations enforced by the FDA and other regulatory agencies through their facilities inspection program. Some
of our contract manufacturers may have never produced a commercially approved pharmaceutical product and therefore have
not  obtained  the  requisite  regulatory  authority  approvals  to  do  so.  The  facilities  and  quality  systems  of  some  or  all  of  our
collaboration partners and third-party contractors must pass a pre-approval inspection for compliance

35

Table of Contents

with  the  applicable  regulations  as  a  condition  of  regulatory  approval  of  our  product  candidates  or  any  of  our  other  potential
products.  In  addition,  the  regulatory  authorities  may,  at  any  time,  audit  or  inspect  a  manufacturing  facility  involved  with  the
preparation of our product candidates or our other potential products or the associated quality systems for compliance with the
regulations applicable to the activities being conducted. Although we oversee the contract manufacturers, we cannot control the
manufacturing  process  of,  and  are  completely  dependent  on,  our  contract  manufacturing  partners  for  compliance  with  the
regulatory requirements. If these facilities do not pass a pre-approval plant inspection, regulatory approval of the products may
not be granted or may be substantially delayed until any violations are corrected to the satisfaction of the regulatory authority, if
ever.

The regulatory authorities also may, at any time following approval of a product for sale, inspect or audit the manufacturing
facilities of our collaboration partners and third-party contractors. If any such inspection or audit identifies a failure to comply with
applicable  regulations  or  if  a  violation  of  our  product  specifications  or  applicable  regulations  occurs  independent  of  such  an
inspection  or  audit,  we  or  the  relevant  regulatory  authority  may  require  remedial  measures  that  may  be  costly  and/or  time
consuming for us or a third party to implement and that may include the temporary or permanent suspension of a clinical study
or commercial sales or the temporary or permanent closure of a facility. Any such remedial measures imposed upon us or third
parties with whom we contract could materially harm our business.

If we, our collaboration partners or any of our third-party manufacturers fail to maintain regulatory compliance, the FDA or
other  applicable  regulatory  authority  can  impose  regulatory  sanctions  including,  among  other  things,  refusal  to  approve  a
pending  application  for  a  new  product  candidate,  withdrawal  of  an  approval  or  suspension  of  production.  As  a  result,  our
business, financial condition and results of operations may be materially harmed.

Additionally,  if  supply  from  one  approved  manufacturer  is  interrupted,  an  alternative  manufacturer  would  need  to  be
qualified through a BLA supplement, NDA supplement or MAA variation or equivalent foreign regulatory filing, which could result
in further delay. The regulatory agencies may also require additional studies if a new manufacturer is relied upon for commercial
production.  Switching  manufacturers  may  involve  substantial  costs  and  is  likely  to  result  in  a  delay  in  our  desired  clinical  and
commercial timelines.

These  factors  could  cause  us  to  incur  additional  costs  and  could  cause  the  delay  or  termination  of  clinical  studies,
regulatory submissions, required approvals or commercialization of our product candidates. Furthermore, if our suppliers fail to
meet  contractual  requirements  and  we  are  unable  to  secure  one  or  more  replacement  suppliers  capable  of  production  at  a
substantially equivalent cost, our clinical studies may be delayed or we could lose potential revenue.

The structure of complex proteins used in protein-based therapeutics is inherently variable and highly dependent on
the processes and conditions used to manufacture them. If we are unable to develop manufacturing processes that
achieve a requisite degree of biosimilarity to the originator drug, and within a range of variability considered
acceptable by regulatory authorities, we may not be able to obtain regulatory approval for our products.

Protein-based  therapeutics  are  inherently  heterogeneous  and  their  structures  are  highly  dependent  on  the  production
process  and  conditions.  Products  from  one  production  facility  can  differ  within  an  acceptable  range  from  those  produced  in
another facility. Similarly, physicochemical differences can also exist among different lots produced within a single facility. The
physicochemical complexity and size of biologic therapeutics create significant technical and scientific challenges in the context
of their replication as biosimilar products.

The inherent variability in protein structure from one production lot to another is a fundamental consideration with respect
to establishing biosimilarity to an originator product to support regulatory approval requirements. For example, the glycosylation
of the protein, meaning the manner in which sugar molecules are attached to the protein backbone of a therapeutic protein when
it is produced in a living cell, is critical to therapeutic efficacy, half-life, efficacy and even safety of the therapeutic and is therefore
a  key  consideration  for  biosimilarity.  Defining  and  understanding  the  variability  of  an  originator  molecule  in  order  to  match  its
glycosylation  profile  requires  significant  skill  in  cell  biology,  protein  purification  and  analytical  protein  chemistry.  Furthermore,
manufacturing  proteins  with  reliable  and  consistent  glycosylation  profiles  at  scale  is  challenging  and  highly  dependent  on  the
skill of the cell biologist and process scientist.

There are extraordinary technical challenges in developing complex protein-based therapeutics that not only must achieve
an acceptable degree of similarity to the originator molecule in terms of characteristics such as the unique glycosylation pattern,
but  also  the  ability  to  develop  manufacturing  processes  that  can  replicate  the  necessary  structural  characteristics  within  an
acceptable range of variability sufficient to satisfy regulatory authorities.

36

Table of Contents

Given the challenges caused by the inherent variability in protein production, we may not be successful in developing our
products if regulators conclude that we have not achieved a sufficient level of biosimilarity to the originator product, or that the
processes we use are unable to generate our products within an acceptable range of variability.

Risks Related to Adverse Events

UDENYCA® or our product candidates may cause undesirable side effects or have other properties that could, as
applicable, delay or prevent their regulatory approval, limit the commercial profile of an approved label or result in
significant negative consequences following marketing approval, if granted.

As with most pharmaceutical products, use of UDENYCA® or our product candidates could be associated with side effects
or  adverse  events,  which  can  vary  in  severity  (from  minor  reactions  to  death)  and  frequency  (infrequent  or  prevalent).  Side
effects or adverse events associated with the use of our product candidates may be observed at any time, including in clinical
trials  or  when  a  product  is  commercialized.  Undesirable  side  effects  caused  by  our  product  candidates  could  cause  us  or
regulatory authorities to interrupt, delay or halt clinical studies and could result in a more restrictive label or the delay or denial of
regulatory  approval  by  the  FDA  or  other  comparable  foreign  authorities.  Results  of  our  studies  could  reveal  a  high  and
unacceptable  severity  and  prevalence  of  side  effects  such  as  toxicity  or  other  safety  issues  and  could  require  us  or  our
collaboration  partners  to  perform  additional  studies  or  halt  development  or  sale  of  these  product  candidates  or  expose  us  to
product liability lawsuits, which will harm our business. In such an event, we may be required by regulatory agencies to conduct
additional animal or human studies regarding the safety and efficacy of our product candidates, which we have not planned or
anticipated  or  our  studies  could  be  suspended  or  terminated,  and  the  FDA  or  comparable  foreign  regulatory  authorities  could
order  us  to  cease  further  development  of  or  deny  or  withdraw  approval  of  our  product  candidates  for  any  or  all  targeted
indications.  There  can  be  no  assurance  that  we  will  resolve  any  issues  related  to  any  product-related  adverse  events  to  the
satisfaction of the FDA or any other regulatory agency in a timely manner, if ever, which could harm our business, prospects and
financial condition.

Additionally,  product  quality  characteristics  have  been  shown  to  be  sensitive  to  changes  in  process  conditions,
manufacturing techniques, equipment or sites and other such related considerations, hence any manufacturing process changes
we implement prior to or after regulatory approval could impact product safety and efficacy.

Drug-related  side  effects  could  affect  patient  recruitment  for  clinical  trials,  the  ability  of  enrolled  patients  to  complete  our
studies or result in potential product liability claims. We currently carry product liability insurance and we are required to maintain
product liability insurance pursuant to certain of our license agreements. We believe our product liability insurance coverage is
sufficient in light of our current clinical programs; however, we may not be able to maintain insurance coverage at a reasonable
cost or in sufficient amounts to protect us against losses due to liability. A successful product liability claim or series of claims
brought  against  us  could  adversely  affect  our  results  of  operations  and  business.  In  addition,  regardless  of  merit  or  eventual
outcome,  product  liability  claims  may  result  in  impairment  of  our  business  reputation,  withdrawal  of  clinical  study  participants,
costs  due  to  related  litigation,  distraction  of  management’s  attention  from  our  primary  business,  initiation  of  investigations  by
regulators, substantial monetary awards to patients or other claimants, the inability to commercialize our product candidates and
decreased demand for our product candidates, if approved for commercial sale.

Additionally,  if  one  or  more  of  our  product  candidates  receives  marketing  approval,  and  we  or  others  later  identify
undesirable  side  effects  caused  by  such  products,  a  number  of  potentially  significant  negative  consequences  could  result,
including but not limited to:

●

●

●

●

●

regulatory authorities may withdraw approvals of such product;

regulatory authorities may require additional warnings on the label;

we  may  be  required  to  create  a  Risk  Evaluation  and  Mitigation  Strategy  (“REMS”),  plan,  which  could  include  a
medication  guide  outlining  the  risks  of  such  side  effects  for  distribution  to  patients,  a  communication  plan  for
healthcare providers and/or other elements to assure safe use;

we could be sued and held liable for harm caused to patients; and

our reputation may suffer.

37

Table of Contents

Any of these events could prevent us from achieving or maintaining market acceptance of the particular product candidate,

if approved, and could significantly harm our business, results of operations and prospects.

If we receive approval for our product candidates, regulatory agencies including the FDA and foreign regulatory agencies,
regulations  require  that  we  report  certain  information  about  adverse  medical  events  if  those  products  may  have  caused  or
contributed to those adverse events. The timing of our obligation to report would be triggered by the date we become aware of
the  adverse  event  as  well  as  the  nature  of  the  event.  We  may  fail  to  report  adverse  events  we  become  aware  of  within  the
prescribed timeframe. We may also fail to appreciate that we have become aware of a reportable adverse event, especially if it
is not reported to us as an adverse event or if it is an adverse event that is unexpected or removed in time from the use of our
products. If we fail to comply with our reporting obligations, the FDA or foreign regulatory agencies could take action including
criminal  prosecution,  the  imposition  of  civil  monetary  penalties,  seizure  of  our  products  or  delay  in  approval  or  clearance  of
future products.

Adverse events involving an originator product, or other biosimilars of such originator product, may negatively affect
our business.

In the event that use of an originator product, or other biosimilar for such originator product, results in unanticipated side
effects  or  other  adverse  events,  it  is  likely  that  our  biosimilar  product  candidate  will  be  viewed  comparably  and  may  become
subject to the same scrutiny and regulatory sanctions as the originator product or other biosimilar, as applicable. Accordingly, we
may become subject to regulatory supervisions, clinical holds, product recalls or other regulatory actions for matters outside of
our  control  that  affect  the  originator  product,  or  other  biosimilar,  as  applicable,  if  and  until  we  are  able  to  demonstrate  to  the
satisfaction  of  our  regulators  that  our  biosimilar  product  candidate  is  not  subject  to  the  same  issues  leading  to  the  regulatory
action as the originator product or other biosimilar, as applicable.

Risks Related to Intellectual Property

If we infringe or are alleged to infringe intellectual property rights of third parties, our business could be harmed. Third-
party claims of intellectual property infringement may prevent or delay our development and commercialization efforts.

Our  commercial  success  depends  in  large  part  on  avoiding  infringement  of  the  patents  and  proprietary  rights  of  third
parties.  There  have  been  many  lawsuits  and  other  proceedings  involving  patent  and  other  intellectual  property  rights  in  the
pharmaceutical  industry,  including  patent  infringement  lawsuits,  interferences,  oppositions  and  reexamination  proceedings
before the United States Patent and Trademark Office (“USPTO”) and corresponding foreign patent offices. Numerous U.S. and
foreign  issued  patents  and  pending  patent  applications,  which  are  owned  by  third  parties,  exist  in  the  fields  in  which  we  are
developing product candidates. As the pharmaceutical industry expands and more patents are issued, the risk increases that our
product candidates may be subject to claims of infringement of the patent rights of third parties.

Our research, development and commercialization activities may infringe or otherwise violate or be claimed to infringe or
otherwise violate patents owned or controlled by other parties. The companies that originated the products for which we intend
to introduce biosimilar versions, such as Amgen, AbbVie and Genentech and Regeneron, as well as other competitors (including
other companies developing biosimilars) have developed, and are continuing to develop, worldwide patent portfolios of varying
sizes and breadth, many of which are in fields relating to our business, and it may not always be clear to industry participants,
including us, which patents cover various types of products or methods of use.

Third parties may assert that we are employing their proprietary technology without authorization. We are aware of third-
party patents or patent applications with claims, for example, to compositions, formulations, methods of manufacture or methods
for  treatment  related  to  the  use  or  manufacture  of  our  product  candidates.  While  we  have  conducted  freedom  to  operate
analyses with respect to UDENYCA® and our product candidates, including our in-licensed biosimilar candidates, as well as our
pipeline candidates, we cannot guarantee that any of our analyses are complete and thorough, nor can we be sure that we have
identified each and every patent and pending application in the United States and abroad that is relevant or necessary to the
commercialization of our product candidates. Moreover, because patent applications can take many years to issue, there may
be currently pending patent applications that may later result in issued patents covering our product candidates. With respect to
products we are evaluating for inclusion in our future biosimilar product pipeline, our freedom to operate analyses, including our
research on the timing of potentially relevant patent expirations, are ongoing.

There  may  also  be  patent  applications  that  have  been  filed  but  not  published  and  if  such  applications  issue  as  patents,
they  could  be  asserted  against  us.  For  example,  in  most  cases,  a  patent  filed  today  would  not  become  known  to  industry
participants for at least 18 months given patent rules applicable in most jurisdictions, which do not require publication of patent
applications until 18 months after filing. Moreover, some U.S. patents may issue without any prior publication in cases where the
patent applicant does not also make a foreign filing. We may also face claims from non-practicing entities that have no relevant
product  revenue  and  against  whom  our  own  patent  portfolio  may  have  no  deterrent  effect.  In  addition,  coverage  of  patents  is
subject to interpretation by the courts, and the interpretation is not always uniform. If we are sued for patent infringement, we
would  need  to  demonstrate  that  our  product  candidates,  products  or  methods  either  do  not  infringe  the  patent  claims  of  the
relevant  patent  or  that  the  patent  claims  are  invalid  and/or  unenforceable,  and  we  may  not  be  able  to  do  this.  Proving  that  a
patent is invalid or unenforceable is difficult. For example, in the United States, proving invalidity requires a showing of clear and
convincing  evidence  to  overcome  the  presumption  of  validity  enjoyed  by  issued  patents.  Also  in  proceedings  before  courts  in
Europe, the burden of proving invalidity of the patent usually rests on the party alleging invalidity. Even if we are successful in
these proceedings, we may incur substantial costs and the time and attention of our management and scientific personnel could
be  diverted  in  pursuing  these  proceedings,  which  could  have  a  material  adverse  effect  on  us.  In  addition,  we  may  not  have
sufficient resources to bring these actions to a successful conclusion.

Third parties could bring claims against us that would cause us to incur substantial expenses and, if successful against us,
could cause us to pay substantial monetary damages. Further, if a patent infringement suit were brought against us, we could be
forced to stop or delay research, development, manufacturing or sales of the product or product candidate that is the subject of
the suit. Ultimately, we could be prevented from commercializing a product or be forced to cease some aspect of our business
operations,  if,  as  a  result  of  actual  or  threatened  patent  infringement  claims,  we  are  unable  to  enter  into  licenses  on
commercially acceptable terms or at all. If, as a result of patent infringement claims or to avoid potential claims, we choose or
are required to seek licenses from third parties, these licenses may not be available on acceptable terms or at all. Even if we are
able to obtain a license, the license may obligate us to pay substantial license fees or royalties or both, and the rights granted to
us might be nonexclusive, which could result in our competitors gaining access to the same intellectual property. Parties making
claims against us may obtain injunctive or other equitable relief, which could effectively block our ability to further develop and
commercialize  one  or  more  of  our  product  candidates.  Defense  of  these  claims,  regardless  of  their  merit,  would  likely  involve
substantial litigation expense and would likely be a substantial diversion of employee resources from our business. In the event
of a successful claim of infringement against us, we may, in addition to being blocked from the market, have to pay substantial
monetary damages, including treble damages and attorneys’ fees for willful infringement, pay royalties, redesign our infringing
products or obtain one or more licenses from third parties, which may be impossible or require substantial time and monetary
expenditure.

On May 10, 2017, Amgen Inc. and Amgen Manufacturing Inc. filed an action against us in the U.S. District Court for the
District of Delaware alleging infringement of one or more claims of Amgen’s US patent 8,273,707 (the “‘707 patent”) under 35
U.S.C.  §  271.  The  complaint  seeks  injunctive  relief,  monetary  damages  and  attorney  fees.  On  December  7,  2017,  the  U.S.
Magistrate Judge issued under seal a Report and Recommendation to the District Court recommending that the District Court
grant, with prejudice, our pending motion to dismiss Amgen’s complaint for failure to state a claim pursuant to Federal Rule of
Civil Procedure 12(b)(6). On March 26, 2018, Judge Stark of the District Court adopted the U.S. Magistrate Judge’s Report and
Recommendation to grant our motion pursuant to Federal Rule of Civil Procedure 12(b)(6) to dismiss with prejudice the patent
infringement complaint alleging infringement of the ‘707 patent on the grounds that such complaint failed to state a claim upon
which relief may be granted. In May 2018, Amgen filed a Notice of Appeal in the U.S. Court of Appeals for the Federal Circuit.
Amgen and Coherus filed briefs in this matter and oral argument was held on May 8, 2019. On July 29, 2019, the Federal Circuit
issued  a  precedential  opinion  affirming  the  District  Court’s  judgment  in  our  favor.  The  Federal  Circuit  held  that  the  doctrine  of
prosecution history estoppel barred Amgen from succeeding on its infringement claim and affirmed the District Court’s dismissal.
In a Joint Status Report, dated September 20, 2019, Amgen stated that it does not intend to further appeal the Federal Circuit’s
decision. On October 11, 2019, we filed a Motion for Attorneys’ Fees with the District Court. Amgen filed its Answering Brief in
Opposition  on  November  8,  2019.  On  November  22,  2019,  we  filed  our  Reply  Brief  with  the  District  Court.  On  November  30,
2020, the District Court issued an order denying the Company’s motion.

On  January  24,  2019,  we  entered  into  settlement  and  license  agreements  with  AbbVie,  that  grant  us  global,  royalty-
bearing,  non-exclusive  license  rights  under  AbbVie’s  intellectual  property  to  commercialize  CHS-1420,  our  proposed
adalimumab (Humira) biosimilar. The global settlements resolve all pending disputes between the parties related to CHS-1420.
Under the U.S. settlement, our license period in the United States commences on July 1, 2023.

In  addition  to  infringement  claims  against  us,  we  may  become  a  party  to  other  patent  litigation  and  other  proceedings,
including interference, IPR, derivation or post-grant proceedings declared or granted by the USPTO and similar proceedings in
foreign countries, regarding intellectual property rights with respect to our current or future products. An unfavorable outcome in
any  such  proceedings  could  require  us  to  cease  using  the  related  technology  or  to  attempt  to  license  rights  to  it  from  the
prevailing party or could cause us to lose valuable intellectual property rights. Our business could be harmed if the prevailing
party does not offer us a license on commercially reasonable terms, if any license is offered at all. Litigation or other proceedings
may  fail  and,  even  if  successful,  may  result  in  substantial  costs  and  distract  our  management  and  other  employees.  We  may
also  become  involved  in  disputes  with  others  regarding  the  ownership  of  intellectual  property  rights.  For  example,  we  jointly
develop intellectual property with certain parties, and disagreements may therefore arise as to the ownership of the intellectual
property  developed  pursuant  to  these  relationships.  If  we  are  unable  to  resolve  these  disputes,  we  could  lose  valuable
intellectual property rights.

Third parties may submit applications for patent term extensions in the United States or other jurisdictions where similar
extensions  are  available  and/or  Supplementary  Protection  Certificates  in  the  E.U.  states  (including  Switzerland)  seeking  to
extend  certain  patent  protection,  which,  if  approved,  may  interfere  with  or  delay  the  launch  of  one  or  more  of  our  biosimilar
products.

The  cost  to  us  of  any  patent  litigation  or  other  proceeding,  even  if  resolved  in  our  favor,  could  be  substantial.  Patent
litigation and other proceedings may fail, and even if successful, may result in substantial costs and distract our management
and other employees. The companies that originated the products for which we intend to introduce biosimilar versions, as well
as other competitors (including other biosimilar companies) may be able to sustain the costs of such litigation or proceedings
more effectively than we can because of their substantially greater financial resources. Uncertainties resulting from the initiation
and continuation of patent litigation or other proceedings could impair our ability to compete in the marketplace.

We do not know whether any of our pending patent applications will result in the issuance of any patents or whether the
rights  granted  under  any  patents  issuing  from  these  applications  will  prevent  any  of  our  competitors  from  marketing  similar
products that may be competitive with our own. Moreover, even if we do obtain issued patents, they will not guarantee us the
right to use our patented technology for commercialization of our product candidates. Third parties may have blocking patents
that could prevent us from commercializing our own products, even if our products use or embody our own, patented inventions.

The  validity  and  enforceability  of  patents  are  generally  uncertain  and  involve  complex  legal  and  factual  questions.  Any
patents that may issue on our pending applications may be challenged, invalidated or circumvented, which could limit our ability
to  stop  competitors  from  marketing  products  similar  to  ours.  Furthermore,  our  competitors  may  develop  similar  or  alternative
technologies not covered by any patents that may issue to us.

For  technologies  for  which  we  do  not  seek  patent  protection,  we  may  rely  on  trade  secrets  to  protect  our  proprietary
position. However, trade secrets are difficult to protect. We seek to protect our technology and product candidates, in part, by
entering  into  confidentiality  agreements  with  those  who  have  access  to  our  confidential  information,  including  our  employees,
consultants, advisors, contractors or collaborators. We also seek to preserve the integrity and confidentiality of our proprietary
technology  and  processes  by  maintaining  physical  security  of  our  premises  and  physical  and  electronic  security  of  our
information  technology  systems.  While  we  have  confidence  in  these  individuals,  organizations  and  systems,  agreements  or
security measures may be breached and we may not have adequate remedies for any breach. In addition, our trade secrets may
otherwise  become  known  or  be  independently  discovered  by  competitors.  To  the  extent  that  our  employees,  consultants,
advisors, contractors and collaborators use intellectual property owned by others in their work for us, disputes may arise as to
the rights in related or resulting know-how and inventions.

We may be involved in lawsuits or IPR proceedings to protect or enforce our patents, which could be expensive, time
consuming and unsuccessful.

We  may  discover  that  competitors  are  infringing  our  issued  patents.  Expensive  and  time-consuming  litigation  may  be
required  to  abate  such  infringement.  We  may  not  prevail  in  any  lawsuits  that  we  initiate  and  the  damages  or  other  remedies
awarded, if any, may not be commercially meaningful. If we or one of our collaboration partners were to initiate legal proceedings
against  a  third  party  to  enforce  a  patent  covering  one  of  our  product  candidates,  the  defendant  could  counterclaim  that  the
patent  covering  our  product  candidate  is  invalid  and/or  unenforceable.  In  patent  litigation  in  the  United  States,  defendant
counterclaims alleging invalidity and/or unenforceability are commonplace. Grounds for a validity challenge could be an alleged
failure to meet any of several statutory requirements, including but not limited to lack of novelty, obviousness or non-enablement.
Grounds  for  an  unenforceability  assertion  could  include  an  allegation  that  someone  involved  in  the  prosecution  of  the  patent
withheld relevant or material information related to the patentability of the

40

Table of Contents

invention  from  the  USPTO  or  made  a  misleading  statement  during  prosecution.  The  outcome  following  legal  assertions  of
invalidity and unenforceability is unpredictable.

Interference  proceedings  provoked  by  third  parties  or  brought  by  us  or  declared  by  the  USPTO  may  be  necessary  to
determine the priority of inventions with respect to our patents or patent applications. An unfavorable outcome could require us
to cease using the related technology or to attempt to license rights to it from the prevailing party. Our business could be harmed
if we cannot obtain a license from the prevailing party on commercially reasonable terms. Third parties may request an IPR of
our patents in the USPTO. An unfavorable decision may result in the revocation of our patent or a limitation to the scope of the
claims of our patents. Our defense of litigation, interference or IPR proceedings may fail and, even if successful, may result in
substantial  costs  and  distract  our  management  and  other  employees.  In  addition,  the  uncertainties  associated  with  litigation
could  have  a  material  adverse  effect  on  our  ability  to  raise  the  funds  necessary  to  continue  our  clinical  trials,  continue  our
research programs, license necessary technology from third parties or enter into development partnerships that would help us
bring our product candidates to market.

Furthermore,  because  of  the  substantial  amount  of  discovery  required  in  connection  with  intellectual  property  litigation,
there is a risk that some of our confidential information could be compromised by disclosure during any litigation we initiate to
enforce our patents. There could also be public announcements of the results of hearings, motions or other interim proceedings
or developments. If securities analysts or investors perceive these results to be negative, it could have a material adverse effect
on the price of our common stock.

We  may  be  subject  to  claims  that  our  employees,  consultants,  or  independent  contractors  have  wrongfully  used  or
disclosed  confidential  information  of  third  parties  or  that  our  employees  have  wrongfully  used  or  disclosed  alleged
trade secrets of their former employers.

We employ individuals, retain independent contractors and consultants and members on our board of directors or scientific

advisory board who were previously employed at universities or other pharmaceutical companies, including our competitors or
potential competitors. For example, our Chief Executive Officer, Dennis M. Lanfear is a former employee of Amgen. Mr. Lanfear
was employed at Amgen during periods when Amgen’s operations included the development and commercialization of Neulasta
and Enbrel. Senior members of our commercial team who will be responsible for any launch of our Neulasta biosimilar formerly
held positions at Amgen. Our board of directors and scientific advisory board include members that were former employees of
Genentech, Amgen and Abbott Laboratories. Although we try to ensure that our employees, consultants and independent
contractors do not use the proprietary information or know-how of others in their work for us, we may be subject to claims that
we or our employees or consultants have inadvertently or otherwise used or disclosed intellectual property, including trade
secrets or other proprietary information, of a former employer or other third parties. Litigation may be necessary to defend
against these claims. If we fail in defending any such claims, in addition to paying monetary damages, we may lose valuable
intellectual property rights or personnel, which could adversely impact our business. Even if we are successful in defending
against such claims, litigation could result in substantial costs and be a distraction to management and other employees.

On March 3, 2017, Amgen Inc. and Amgen USA Inc. (collectively “Amgen”) filed an action against us, KBI Biopharma Inc.,
our  employee  Howard  S.  Weiser  and  Does  1-20  in  the  Superior  Court  of  the  State  of  California,  County  of  Ventura.  The
complaint, which was amended, alleged that we engaged in unfair competition and improperly solicited and hired certain former
Amgen  employees  in  order  to  acquire  and  access  trade  secrets  and  other  confidential  information  belonging  to  Amgen.  The
complaint,  as  amended,  sought  injunctive  relief  and  monetary  damages.  On  May  2,  2019,  we  and  Amgen  settled  the  trade
secret  action  brought  by  Amgen.  The  details  of  the  settlement  are  confidential  but  the  Company  will  continue  to  market
UDENYCA® and began paying a mid-single digit royalty to Amgen for five years starting on July 1, 2019.

If we fail to comply with our obligations in the agreements under which we license intellectual property and other rights
from third parties or otherwise experience disruptions to our business relationships with our licensors, we could lose
license rights that are important to our business.

We  are  a  party  to  certain  non-exclusive  intellectual  property  license  agreements  with  certain  vendors  (pertaining  to
mammalian cell lines) and with AbbVie (pertaining to AbbVie’s intellectual property related to CHS-1420) that are important to
our business, and we expect to enter into additional license agreements in the future. Our existing license agreements impose,
and we expect that future license agreements will impose, various diligence, milestone payment, royalty and other obligations on
us. If we fail to comply with our obligations under these agreements or we are subject to a bankruptcy, we may be required to
make certain payments to the licensor, we may lose the license or the licensor may have the right to terminate the license, in
which event we would not be able to develop or market products covered by the license. Additionally, the milestone and other
payments associated with these licenses will make it less profitable for us to develop our product candidates.

41

Table of Contents

In the event we breach any of our obligations related to such agreements, we may incur significant liability to our licensing

partners. Disputes may arise regarding intellectual property subject to a licensing agreement, including but not limited to:

●

●

●

●

●

●

the scope of rights granted under the license agreement and other interpretation-related issues;

the extent to which our technology and processes infringe on intellectual property of the licensor that is not subject to
the licensing agreement;

the sublicensing of patents and other rights;

our diligence obligations under the license agreement and what activities satisfy those diligence obligations;

the  ownership  of  inventions  and  know-how  resulting  from  the  joint  creation  or  use  of  intellectual  property  by  our
licensors and us and our collaborators; and

the priority of invention of patented technology.

If  disputes  over  intellectual  property  and  other  rights  that  we  have  licensed  prevent  or  impair  our  ability  to  maintain  our
current licensing arrangements on acceptable terms, we may be unable to successfully develop and commercialize the affected
product candidates and that could have a material adverse effect on our business.

We may not be successful in obtaining or maintaining necessary rights to our product candidates through acquisitions
and in-licenses.

We currently have rights to certain intellectual property, through licenses from third parties and under patent applications
that we own, to develop our biosimilar product candidates. Because we may find that our programs require the use of proprietary
rights  held  by  third  parties,  the  growth  of  our  business  may  depend  in  part  on  our  ability  to  acquire,  in-license  or  use  these
proprietary  rights.  We  may  be  unable  to  acquire  or  in-license  compositions,  methods  of  use,  processes  or  other  third  party
intellectual  property  rights  from  third  parties  that  we  identify  as  necessary  for  our  product  candidates.  The  licensing  and
acquisition of third-party intellectual property rights is a competitive area, and a number of more established companies are also
pursuing  strategies  to  license  or  acquire  third-party  intellectual  property  rights  that  we  may  consider  attractive.  These
established  companies  may  have  a  competitive  advantage  over  us  due  to  their  size,  financial  resources  and  greater  clinical
development and commercialization capabilities. In addition, companies that perceive us to be a competitor may be unwilling to
assign or license rights to us. We also may be unable to license or acquire third-party intellectual property rights on terms that
would allow us to make an appropriate return on our investment.

If we are unable to successfully obtain required third party intellectual property rights or maintain the existing intellectual
property rights we have, we may have to abandon development of that program and our business and financial condition could
suffer.

Our ability to market our products in the United States may be significantly delayed or prevented by the BPCIA patent
dispute resolution mechanism.

The Biologics Price Competition and Innovation Act of 2009, Title VII, Subtitle A of the Patent Protection and Affordable
Care Act, Pub. L. No. 111-148, 124 Stat. 119, Sections 7001-02 signed into law March 23, 2010, and codified in 42 U.S.C. §262,
(the  “BPCIA”),  created  an  elaborate  and  complex  patent  dispute  resolution  mechanism  for  biosimilars  that,  if  we  choose  to
implement  it,  could  prevent  us  from  launching  our  product  candidates  in  the  United  States  or  could  substantially  delay  such
launches. However, even if we elect not to implement this mechanism, the launch of our products in the United States could still
be  prevented  or  substantially  delayed  by  intellectual  property  disputes  with  originator  companies  that  market  the  reference
products on which our biosimilar products are based.

The BPCIA establishes a patent disclosure and briefing process between the biosimilar applicant and the originator that is
demanding and time-sensitive. While certain aspects of this process are still being tested in the federal courts, the U.S. Supreme
Court, as discussed further below, recently ruled that this process is not mandatory, such that a biosimilar applicant may elect to
engage  in  this  process,  but  is  not  required  to  do  so.  The  following  is  an  overview  of  the  patent  exchange  and  patent  briefing
procedures established by the BPCIA for biosimilar applicants that elect to employ them:

1.

2.

Disclosure of the Biosimilar Application. Within 20 days after the FDA publishes a notice that its application has been
accepted for review, a 351(k) biosimilar applicant may elect to provide a copy of its application to the originator if it
chooses to engage in the BPCIA patent exchange mechanism.

Identification of Pertinent Patents. Within 60 days of the date of receipt of the application the originator must identify
patents owned or controlled by the originator, which it believes could be asserted against the biosimilar applicant.

42

Statement  by  the  Biosimilar  Applicant.  Following  the  receipt  of  the  originator’s  patent  list,  the  biosimilar  applicant
must state either that it will not market its product until the relevant patents have expired or alternatively provide its
arguments that the patents are invalid, unenforceable or would not be infringed by the proposed biosimilar product
candidate. The biosimilar applicant may also provide the originator with a list of patents it believes the brand-name
firm could assert against the reference product.

Statement  by  the  Originator.  In  the  event  the  biosimilar  applicant  has  asserted  that  the  patents  are  invalid,
unenforceable or would not be infringed by the proposed follow-on product, the originator must provide the biosimilar
applicant with a response within 60 days. The response must provide the legal and factual basis of the opinion that
such patent will be infringed by the commercial marketing of the proposed biosimilar.

Patent  Resolution  Negotiations.  If  the  originator  provides  its  detailed  views  that  the  proposed  biosimilar  would
infringe valid and enforceable patents, then the parties are required to engage in good faith negotiations to identify
which of the discussed patents will be the subject of a patent infringement action. If the parties agree on the patents
to be litigated, the brand-name firm must bring an action for patent infringement within 30 days.

Simultaneous  Exchange  of  Patents.  If  those  negotiations  do  not  result  in  an  agreement  within  15  days,  then  the
biosimilar applicant must notify the originator of how many patents (but not the identity of those patents) that it wishes
to litigate. Within five days, the parties are then required to exchange lists identifying the patents to be litigated. The
number  of  patents  identified  by  the  originator  may  not  exceed  the  number  provided  by  the  biosimilar  applicant.
However, if the biosimilar applicant previously indicated that no patents should be litigated, then the originator may
identify one patent.

Commencement  of  Patent  Litigation.  The  originator  must  then  commence  patent  infringement  litigation  within  30
days.  That  litigation  will  involve  all  of  the  patents  on  the  originator’s  list  and  all  of  the  patents  on  the  follow-on
applicant’s list. The follow-on applicant must then notify the FDA of the litigation. The FDA must then publish a notice
of the litigation in the Federal Register.

Notice of Commercial Marketing. The BPCIA requires the biosimilar applicant to provide notice to the originator 180
days in advance of its first commercial marketing of its proposed follow-on biologic. The originator is allowed to seek
a preliminary injunction blocking such marketing based upon any patents that either party had preliminarily identified,
but  were  not  subject  to  the  initial  phase  of  patent  litigation.  The  litigants  are  required  to  “reasonably  cooperate  to
expedite  such  further  discovery  as  is  needed”  with  respect  to  the  preliminary  injunction  motion.  The  federal  courts
have not yet settled the issue as to when, or under what circumstances, the biosimilar applicant must provide the 180
notice of commercial marketing provided in the BPCIA.

On  June  12,  2017,  the  Supreme  Court  issued  its  decision  in  Amgen  v.  Sandoz,  holding  that  (i)  the  “patent  dance”  is
optional;  and  (ii)  the  180-day  pre-marketing  notification  may  be  given  either  before  or  after  receiving  FDA  approval  of  the
biosimilar product. The Supreme Court declined to rule whether a state injunctive remedy may be available to the originator and
remanded that question to the Federal Circuit for further consideration. On December 14, 2017, the Federal Circuit decided that
state law claims are preempted by the BPCIA on both field and conflict grounds.

A  significant  legal  risk  for  a  biosimilar  applicant  that  pursues  regulatory  approval  under  the  351(k)  regulatory  approval
route, and also elects to engage in the above-described BPCIA patent exchange mechanism, is that the process could result in
the  initiation  of  patent  infringement  litigation  prior  to  FDA  approval  of  a  351(k)  application,  and  such  litigation  could  result  in
blocking the market entry of the biosimilar product. However, even if biosimilar applicants opt out of the BPCIA patent exchange
process, originators will still have the right to assert patent infringement as a basis to enjoin a biosimilar product launch. Thus,
whether  or  not  we  engage  in  the  BPCIA  patent  exchange  process,  there  is  risk  that  patent  infringement  litigation  initiated  by
originators could prevent us indefinitely from launching our biosimilar products.

The  legal  and  strategic  considerations  weighing  for  or  against  a  decision  to  voluntarily  engage  in  the  BPCIA  patent
exchange  process  are  complex  and  will  differ  on  a  product-by-product  basis.  If  we  decide  to  engage  in  the  BPCIA  patent
exchange  process,  preparing  for  and  conducting  the  patent  exchange,  briefing  and  negotiation  process  outlined  above  will
require  extraordinarily  sophisticated  legal  counseling  and  extensive  planning,  all  under  extremely  tight  deadlines.  Moreover,  it
may  be  difficult  for  us  to  secure  or  retain  such  legal  support  if  large,  well-funded  originators  have  already  entered  into
engagements with highly qualified law firms or if the most highly qualified law firms choose not to represent biosimilar applicants
due to their long-standing relationships with originators.

Under the complex, and uncertain rules of the BPCIA patent provisions, coupled with the inherent uncertainty surrounding
the legal interpretation of any originator patents that might be asserted against us in this new process, we see substantial risk
that the BPCIA process may significantly delay or defeat our ability to market our products in the United States, or may result in
us incurring substantial legal settlement costs.

Risks Related to the Discovery and Development of Our Product Candidates

We are heavily dependent on the development, clinical success, regulatory approval and commercial success of our
product candidates. We cannot give any assurance that any of our product candidates will receive regulatory approval,
which is necessary before they can be commercialized.

We invested substantially all of our efforts and financial resources to identify, acquire and develop our product candidates.
Our  future  success  is  dependent  on  our  ability  to  develop,  obtain  regulatory  approval  for,  and  then  commercialize  and  obtain
adequate  third  party  coverage  and  reimbursement  for  one  or  more  of  our  product  candidates.  We  currently  do  not  have  any
approved products, other than UDENYCA®.

Our product candidates are in varying stages of development and will require additional clinical development, management
of  nonclinical,  clinical  and  manufacturing  activities,  regulatory  approval,  adequate  manufacturing  supplies,  commercial
organization and significant marketing efforts before we generate any revenue from product sales. For example, CHS-1420 has
completed Phase 3 clinical trials or other 351(k) BLA-enabling clinical development. Other than certain PK bridging studies, we
have not yet initiated phase 3 clinical trials for toripalimab and any other product in our pipeline. It may be some time before we
file for market approval with the relevant regulatory agencies for these product candidates.

We cannot be certain that any of our product candidates will be successful in clinical trials or receive regulatory approval.
Further, our product candidates may not receive regulatory approval even if they are successful in clinical trials. If we and our
existing or future collaboration partners do not receive regulatory approvals for our product candidates, we may not be able to
continue our operations.

We,  together  with  our  collaboration  partners,  generally  plan  to  seek  regulatory  approval  to  commercialize  our  product
candidates in the United States, the E.U., and additional foreign countries where we or our partners have commercial rights. To
obtain regulatory approval, we and our collaboration partners must comply with numerous and varying regulatory requirements
of  such  countries  regarding  safety,  efficacy,  chemistry,  manufacturing  and  controls,  clinical  studies,  commercial  sales,  and
pricing and distribution of our product candidates. Even if we and our collaboration partners are successful in obtaining approval
in one jurisdiction, we cannot ensure that we will obtain approval in any other jurisdictions. For example, Innovent’s bevacizumab
(Avastin)  biosimlar  product  candidate  has  been  developed  principally  in  China,  and  the  FDA  may  not  agree  that  Innovent’s
clinical development plan, even if successfully completed, will support submission of a 351(k) BLA. If we and our collaboration
partners are unable to obtain approval for our product candidates in multiple jurisdictions, our revenue and results of operations
could be negatively affected.

The regulatory approval processes of the FDA, EMA and comparable foreign authorities are lengthy, time consuming
and inherently unpredictable, and the regulatory approval requirements for biosimilars are evolving. If we and our
collaboration partners are ultimately unable to obtain regulatory approval for our product candidates, our business will
be substantially harmed.

The  research,  development,  testing,  manufacturing,  labeling,  packaging,  approval,  promotion,  advertising,  storage,
marketing,  distribution,  post-approval  monitoring  and  reporting  and  export  and  import  of  biologic  and  biosimilar  products  are
subject  to  extensive  regulation  by  the  FDA  and  other  regulatory  authorities  in  the  United  States,  by  the  EMA  and  EEA
Competent  Authorities  in  the  European  Economic  Area  (“EEA”),  and  by  other  regulatory  authorities  in  other  countries,  where
regulations differ from country to country. Neither we nor any existing or future collaboration partners are permitted to market our
product candidates in the United States until we and our collaboration partners receive approval from the FDA, or in the EEA
until we and our collaboration partners receive EC or EEA Competent Authority approvals.

The time required to obtain approval by the FDA and comparable foreign authorities is unpredictable, may take many years
following the completion of clinical studies and depends upon numerous factors. In addition, approval policies, regulations or the
type  and  amount  of  clinical  data  necessary  to  gain  approval  may  change  during  the  course  of  a  product  candidate’s  clinical
development  and  may  vary  among  jurisdictions,  which  may  cause  delays  in  the  approval  or  the  decision  not  to  approve  an
application. For example, during FDA’s review of Bioeq’s 351(k) BLA for its ranibizumab (Lucentis) biosimilar, the FDA requested
that Bioeq submit additional manufacturing data

44

Table of Contents

for  the  equipment  in  its  new  location,  leading  Bioeq  to  withdraw  its  351(k)  BLA  for  this  candidate  in  order  to  provide  the
requested  data  and  resubmit  the  application  thereafter.  Neither  we  nor  any  collaboration  partner  has  obtained  regulatory
approval for any of our product candidates, other than UDENYCA®, and it is possible that none of our other current or future
product candidates will ever obtain regulatory approval.

Applications for our product candidates could fail to receive regulatory approval for many reasons, including but not limited

to the following:

●

●

●

●

●

●

●

the data collected from clinical studies of our product candidates may not be sufficient to support the submission of
an original BLA, an NDA, a biosimilar product application under the 351(k) pathway of the Public Health Service Act
(“PHSA”), a biosimilar marketing authorization under Article 6 of Regulation (EC) No. 726/2004 and/or Article 10(4) of
Directive 2001/83/EC in the EEA or other submission or to obtain regulatory approval in the United States, the EEA
or elsewhere;

the FDA or comparable foreign regulatory authorities may disagree with the design or implementation of our clinical
studies;

the population studied in the clinical program may not be sufficiently broad or representative to assure safety in the
full population for which we seek approval;

the FDA or comparable foreign regulatory authorities may disagree with our interpretation of data from analytical and
bioanalytical studies, nonclinical studies or clinical studies;

we may be unable to demonstrate to the FDA or comparable foreign regulatory authorities that a product candidate’s
risk-benefit ratio for its proposed indication is acceptable;

the  FDA  or  comparable  foreign  regulatory  authorities  may  fail  to  approve  the  manufacturing  processes,  test
procedures and specifications or facilities of our collaborators or third-party manufacturers with which we contract for
clinical and commercial supplies; and

the approval policies or regulations of the FDA or comparable foreign regulatory authorities may significantly change
in a manner rendering our clinical data insufficient for approval.

This  approval  process,  as  well  as  the  unpredictability  of  the  results  of  clinical  studies,  may  result  in  our  failure  to  obtain
regulatory  approval  to  market  any  of  our  product  candidates,  which  would  significantly  harm  our  business.  Any  delays  in  the
commencement or completion of clinical testing could significantly impact our product development costs and could result in the
need for additional financing.

If  we  are  not  able  to  demonstrate  biosimilarity  of  our  biosimilar  product  candidates  to  the  satisfaction  of  regulatory
authorities,  we  will  not  obtain  regulatory  approval  for  commercial  sale  of  our  biosimilar  product  candidates  and  our
future results of operations would be adversely affected.

Our  future  results  of  operations  depend,  to  a  significant  degree,  on  our  ability  to  obtain  regulatory  approval  for  and  to
commercialize  our  proposed  biosimilar  products.  To  obtain  regulatory  approval  for  the  commercial  sale  of  these  product
candidates,  we  will  be  required  to  demonstrate  to  the  satisfaction  of  regulatory  authorities,  among  other  things,  that  our
proposed  biosimilar  products  are  highly  similar  to  biological  reference  products  already  licensed  by  the  regulatory  authority
pursuant to marketing applications, notwithstanding minor differences in clinically inactive components, and that they have no
clinically meaningful differences as compared to the marketed biological products in terms of the safety, purity and potency of
the  products.  Each  individual  jurisdiction  may  apply  different  criteria  to  assess  biosimilarity,  based  on  a  preponderance  of  the
evidence  that  can  be  interpreted  subjectively  in  some  cases.  In  the  EEA,  the  similar  nature  of  a  biosimilar  and  a  reference
product is demonstrated by comprehensive comparability studies covering quality, biological activity, safety and efficacy.

It  is  uncertain  if  regulatory  authorities  will  grant  the  full  originator  label  to  biosimilar  product  candidates  when  they  are
approved. For example, an infliximab (Remicade) biosimilar molecule was approved in Europe and in the United States for the
full originator label but received a much narrower originator label when initially approved in Canada. That infliximab biosimilar
only received full label extension in Canada in 2016 after providing additional clinical data. A similar outcome could occur with
respect to our product candidates and there is no guarantee that our product candidates will receive a full originator label even
after the provision of additional clinical data.

In  the  event  that  regulatory  authorities  require  us  to  conduct  additional  clinical  trials  or  other  lengthy  processes,  the
commercialization of our proposed biosimilar products could be delayed or prevented. Delays in the commercialization of or the
inability

45

Table of Contents

to obtain regulatory approval for these products could adversely affect our operating results by restricting or significantly delaying
our introduction of new biosimilars.

Clinical drug development involves a lengthy and expensive process and we may encounter substantial delays in our
clinical studies or may fail to demonstrate safety and efficacy to the satisfaction of applicable regulatory authorities.

Before  obtaining  marketing  approval  from  regulatory  authorities  for  the  sale  of  our  product  candidates,  we  (and/or  our
collaboration partners) must conduct clinical studies to demonstrate the safety and efficacy of the product candidates in humans.

Clinical  testing  is  expensive  and  can  take  many  years  to  complete,  and  its  outcome  is  inherently  uncertain.  Failure  can
occur  at  any  time  during  the  clinical  study  process.  The  results  of  preclinical  studies  and  early  clinical  studies  of  our  product
candidates  may  not  be  predictive  of  the  results  of  later-stage  clinical  studies.  Product  candidates  that  have  shown  promising
results  in  early-stage  clinical  studies  may  still  suffer  significant  setbacks  in  subsequent  registration  clinical  studies.  There  is  a
high  failure  rate  for  product  candidates  proceeding  through  clinical  studies,  and  product  candidates  in  later  stages  of  clinical
studies may fail to show the desired safety and efficacy traits despite having progressed through preclinical studies and initial
clinical studies. A number of companies in the biopharmaceutical industry have suffered significant setbacks in advanced clinical
studies  due  to  lack  of  efficacy  or  adverse  safety  profiles,  notwithstanding  promising  results  in  earlier  studies.  Nonclinical  and
clinical data are also often susceptible to varying interpretations and analyses. We do not know whether any clinical studies we
may  conduct  for  our  product  candidates  will  demonstrate  consistent  or  adequate  efficacy  and  safety  to  obtain  regulatory
approval. Furthermore, biosimilar clinical studies must use originator products as comparators, and such supplies may not be
available on a timely basis to support such trials.

We cannot guarantee that any clinical studies will be conducted as planned or completed on schedule, if at all. A failure of
one or more clinical studies can occur at any stage of testing, and our future clinical studies may not be successful. Events that
may prevent successful or timely completion of clinical development include but are not limited to:

●

●

●

●

●

●

●

●

●

●

●

●

●

●

inability to generate sufficient preclinical, toxicology or other in vivo or in vitro data to support the initiation of human
clinical studies;

delays in reaching a consensus with regulatory agencies on study design;

delays in reaching agreement on acceptable terms with prospective contract research organizations (“CROs”), and
clinical  study  sites,  the  terms  of  which  can  be  subject  to  extensive  negotiation  and  may  vary  significantly  among
different CROs and clinical study sites;

delays in obtaining required Institutional Review Board (“IRB”), approval at each clinical study site;

imposition of a clinical hold by regulatory agencies, after review of an investigational new drug (“IND”), application or
amendment or equivalent application or amendment, or an inspection of our clinical study operations or study sites or
as a result of adverse events reported during a clinical trial;

delays in recruiting suitable patients to participate in our clinical studies sponsored by us or our partners;

difficulty collaborating with patient groups and investigators;

failure by our CROs, other third parties or us to adhere to clinical study requirements;

failure  to  perform  in  accordance  with  the  FDA’s  good  clinical  practices  requirements  or  applicable  regulatory
guidelines in other countries;

delays in patients completing participation in a study or return for post-treatment follow-up, or patients dropping out of
a study;

occurrence  of  adverse  events  associated  with  the  product  candidate  that  are  viewed  to  outweigh  its  potential
benefits;

changes in regulatory requirements and guidance that require amending or submitting new clinical protocols;

the cost of clinical studies of our product candidates being greater than we anticipate;

clinical studies of our product candidates producing negative or inconclusive results, which may result in us deciding
or regulators requiring us to conduct additional clinical studies or abandon product development programs; and

46

Table of Contents

●

delays  in  manufacturing,  testing,  releasing,  validating  or  importing/exporting  and/or  distributing  sufficient  stable
quantities of our product candidates and originator products for use in clinical studies or the inability to do any of the
foregoing.

In addition, disruptions caused by the COVID-19 pandemic may increase the likelihood that we encounter such difficulties
or  delays  in  initiating,  enrolling,  or  conducting  our  planned  clinical  trials.  Any  inability  to  successfully  complete  nonclinical  and
clinical  development  could  result  in  additional  costs  to  us  or  impair  our  ability  to  generate  revenue.  In  addition,  if  we  make
manufacturing  or  formulation  changes  to  our  product  candidates,  we  may  need  to  conduct  additional  studies  to  bridge  our
modified  product  candidates  to  earlier  versions.  For  example,  we  altered  the  manufacturing  processes  for  CHS-1420  and  will
need to provide data to the FDA and foreign regulatory authorities demonstrating that the change in manufacturing process has
not changed the product candidate. If we are unable to make that demonstration to the FDA or comparable foreign regulatory
authorities, we could face significant delays or fail to obtain regulatory approval to market the product, which could significantly
harm our business.

The development, manufacture and commercialization of biosimilar products under various global regulatory pathways
pose unique risks.

We  and  our  collaboration  partners  intend  to  pursue  market  authorization  globally.  In  the  United  States,  an  abbreviated
pathway for approval of biosimilar products was established by the BPCIA, enacted on March 23, 2010, as part of the ACA. The
BPCIA established this abbreviated pathway under section 351(k) of the PHSA. Subsequent to the enactment of the BPCIA, the
FDA issued guidance documents regarding the demonstration of biosimilarity and interchangeability as well as the submission
and  review  of  biosimilar  applications.  Moreover,  market  acceptance  of  biosimilar  products  in  the  United  States  is  unclear.
Numerous states are considering or have already enacted laws that regulate or restrict the substitution by state pharmacies of
biosimilars  for  originator  products  already  licensed  by  the  FDA.  Market  success  of  biosimilar  products  will  depend  on
demonstrating  to  patients,  physicians,  payers  and  relevant  authorities  that  such  products  are  similar  in  quality,  safety  and
efficacy as compared to the reference product.

We will continue to analyze and incorporate into our biosimilar development plans any final regulations issued by the FDA,
pharmacy  substitution  policies  enacted  by  state  governments  and  other  applicable  requirements  established  by  relevant
authorities. The costs of development and approval, along with the probability of success for our biosimilar product candidates,
will be dependent upon the application of any laws and regulations issued by the relevant regulatory authorities.

Biosimilar  products  may  also  be  subject  to  extensive  originator-controlled  patent  portfolios  and  patent  infringement
litigation, which may delay and could prevent the commercial launch of a product. Moreover, the BPCIA prohibits the FDA from
accepting an application for a biosimilar candidate to a reference product within four years of the reference product’s licensure
by  the  FDA.  In  addition,  the  BPCIA  provides  innovative  biologics  with  12  years  of  exclusivity  from  the  date  of  their  licensure,
during which time the FDA cannot approve any application for a biosimilar candidate to the reference product.

The  BPCIA  is  complex  and  continues  to  be  interpreted  and  implemented  by  the  FDA.  As  a  result,  its  ultimate  impact,
implementation and meaning are evolving and remain subject to significant uncertainty. Future implementation decisions by the
FDA  could  result  in  delays  in  the  development  or  commercialization  of  our  product  candidates  or  increased  costs  to  assure
regulatory compliance and could adversely affect our operating results by restricting or significantly delaying our ability to market
new  biosimilar  products.  Moreover,  the  Trump  administration  has  taken  several  executive  actions,  including  the  issuance  of  a
number of Executive Orders, that could impose significant burdens on, or otherwise materially delay, the FDA’s ability to engage
in  routine  regulatory  and  oversight  activities  such  as  implementing  statutes  through  rulemaking,  issuance  of  guidance,  and
review  and  approval  of  marketing  applications.  It  is  difficult  to  predict  how  these  Executive  Orders  will  be  interpreted  and
implemented, and the extent to which they will impact the FDA’s ability to continue implementing the BPCIA and engage in its
other  regulatory  authorities  under  the  FDA.  If  these  executive  actions  impose  restrictions  on  the  FDA’s  ability  to  engage  in
oversight and implementation activities in the normal course, our business may be negatively impacted.

Under current E.U. regulations, an application for regulatory approval of a biosimilar drug cannot be submitted in the E.U.
until  expiration  of  an  eight-year  data  exclusivity  period  for  the  reference  (originator)  product,  measured  from  the  date  of  the
reference  product’s  initial  marketing  authorization.  Furthermore,  once  approved,  the  biosimilar  cannot  be  marketed  until
expiration of a ten-year period following the initial marketing authorization of the reference product, such ten-year period being
extendible  to  11  years  if  the  reference  product  received  approval  of  an  additional  therapeutic  indication,  within  the  first  eight
years following its initial marketing authorization, representing a significant clinical benefit in comparison with existing therapies.

In Europe, the approval of a biosimilar for marketing is based on an opinion issued by the EMA and a decision issued by
the EC. Therefore, the marketing approval will cover the entire EEA. However, substitution of a biosimilar for the originator is a
decision  that  is  made  at  the  national  level.  Additionally,  a  number  of  countries  do  not  permit  the  automatic  substitution  of
biosimilars for the originator product. Therefore, even if we obtain marketing approval for the entire EEA, we may not receive
substitution in one or more European nations, thereby restricting our ability to market our products in those jurisdictions.

Other regions, including Canada, Japan and Korea, also have their own legislation outlining a regulatory pathway for the
approval of biosimilars. In some cases other countries have either adopted European guidance (Singapore and Malaysia) or are
following  guidance  issued  by  the  World  Health  Organization  (Cuba  and  Brazil).  While  there  is  overlap  in  the  regulatory
requirements across regions, there are also some areas of non-overlap. Additionally, we cannot predict whether countries that
we may wish to market in which do not yet have an established or tested regulatory framework could decide to issue regulations
or  guidance  and/or  adopt  a  more  conservative  viewpoint  than  other  regions.  Therefore,  it  is  possible  that  even  if  we  obtain
agreement  from  one  health  authority  to  an  accelerated  or  optimized  development  plan,  we  will  need  to  defer  to  the  most
conservative view to ensure global harmonization of the development plan. Also, for regions where regulatory authorities do not
yet have sufficient experience in the review and approval of a biosimilar product, these authorities may rely on the approval from
another  region  (e.g.,  the  U.S.  or  the  E.U.),  which  could  delay  our  approval  in  that  region.  Finally,  it  is  possible  that  some
countries will not approve a biosimilar without clinical data from their population and/or may require that the biosimilar product be
manufactured within their region.

If  other  biosimilars  of  pegfilgrastim  (Neulasta),  bevacizumab  (Avastin),  ranibizumab  (Lucentis),  aflibercept  (Eylea)  or
adalimumab  (Humira),  are  determined  to  be  interchangeable  and  our  biosimilar  candidates  for  these  originator
products are not, our business would suffer.

The  FDA  or  other  relevant  regulatory  authorities  may  determine  that  a  proposed  biosimilar  product  is  “interchangeable”
with  a  reference  product,  meaning  that  the  biosimilar  product  may  be  substituted  for  the  reference  product  without  the
intervention of the health care provider who prescribed the reference product, if the application includes sufficient information to
show that the product is biosimilar to the reference product and that it can be expected to produce the same clinical result as the
reference product in any given patient. If the biosimilar product may be administered more than once to a patient, the applicant
must demonstrate that the risk in terms of safety or diminished efficacy of alternating or switching between the biosimilar product
candidate and the reference product is not greater than the risk of using the reference product without such alternation or switch.
To make a final determination of interchangeability, regulatory authorities may require additional confirmatory information beyond
what we plan to initially submit in our applications for approval, such as more in-depth analytical characterization, animal testing
or further clinical studies. Provision of sufficient information for approval may prove difficult and expensive.

We  cannot  predict  whether  any  of  our  biosimilar  product  candidates  will  meet  regulatory  authority  requirements  for
approval  not  only  as  a  biosimilar  product  but  also  as  an  interchangeable  product  in  any  jurisdiction.  Furthermore,  legislation
governing interchangeability could differ by jurisdiction on a state or national level worldwide.

The labelling of “interchangeability” is important because, in the United States for example, the first biosimilar determined
to be interchangeable with a particular reference, or originator, product for any condition of use is eligible for a period of market
exclusivity  that  delays  a  FDA  determination  that  a  second  or  subsequent  biosimilar  product  is  interchangeable  with  that
originator  product  for  any  condition  of  use  until  the  earlier  of:  (1)  one  year  after  the  first  commercial  marketing  of  the  first
interchangeable  product;  (2)  18  months  after  resolution  of  a  patent  infringement  suit  instituted  under  42  U.S.C.  §  262(l)(6)
against  the  applicant  that  submitted  the  application  for  the  first  interchangeable  product,  based  on  a  final  court  decision
regarding all of the patents in the litigation or dismissal of the litigation with or without prejudice; (3) 42 months after approval of
the  first  interchangeable  product,  if  a  patent  infringement  suit  instituted  under  42  U.S.C.  §  262(l)(6)  against  the  applicant  that
submitted  the  application  for  the  first  interchangeable  product  is  still  ongoing;  or  (4)  18  months  after  approval  of  the  first
interchangeable product if the applicant that submitted the application for the first interchangeable product has not been sued
under 42 U.S.C. § 262(l)(6). Thus, a determination that another company’s product is interchangeable with the originator biologic
before  we  obtain  approval  of  our  corresponding  biosimilar  product  candidates  may  delay  the  potential  determination  that  our
products are interchangeable with the originator product, which could materially adversely affect our results of operations and
delay, prevent or limit our ability to generate revenue.

Failure to obtain regulatory approval in any targeted regulatory jurisdiction would prevent us from marketing our
products to a larger patient population and reduce our commercial opportunities.

We are marketing UDENYCA® in the United States, and subject to product approvals and relevant patent expirations, we
intend to market our other biosimilar products in the United States and outside the U.S. on our own or with future collaboration
partners.  We  entered  into  a  distribution  agreement  with  our  licensee  Orox  for  the  commercialization  of  biosimilar  versions  of
etanercept  (Enbrel),  rituximab  (Rituxan),  adalimumab  (Humira)  and  pegfilgrastim  (Neulasta)  in  certain  Caribbean  and  Latin
American  countries.  We  intend  to  market  our  biosimilar  product  candidates  in  the  United  States  and  may  seek  to  partner
commercially all biosimilars outside the U.S.

In order to market our products in the E.U., the U.S. and other jurisdictions, we and our collaboration partners must obtain
separate regulatory approvals and comply with numerous and varying regulatory requirements. The EMA is responsible for the
centralized  procedure  for  the  regulation  and  approval  of  human  medicines.  This  procedure  results  in  a  single  marketing
authorization  that  is  valid  in  all  E.U.  countries,  as  well  as  in  Iceland,  Liechtenstein  and  Norway.  The  time  required  to  obtain
approval abroad may differ from that required to obtain FDA approval. The foreign regulatory approval process may include all of
the risks associated with obtaining FDA approval and we may not obtain foreign regulatory approvals on a timely basis, if at all.
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  foreign  countries  or  by  the  FDA.  We  or  our
collaboration  partners  may  not  be  able  to  file  for  regulatory  approvals  and  may  not  receive  necessary  approvals  to
commercialize our products in any market. Failure to obtain these approvals would materially and adversely affect our business,
financial condition and results of operations.

We may not be successful in our efforts to identify, develop or commercialize additional product candidates.

Although  a  substantial  amount  of  our  effort  will  focus  on  the  continued  clinical  testing,  potential  approval  and
commercialization  of  our  existing  product  candidates,  the  success  of  our  business  also  depends  upon  our  ability  to  identify,
develop  and  commercialize  additional  product  candidates.  Research  programs  to  identify  new  product  candidates  require
substantial technical, financial and human resources. We may focus our efforts and resources on potential programs or product
candidates  that  ultimately  prove  to  be  unsuccessful.  Our  development  efforts  may  fail  to  yield  additional  product  candidates
suitable for clinical development and commercialization for a number of reasons, including but not limited to the following:

●

●

●

●

●

●

we may not be successful in identifying potential product candidates that pass our strict screening criteria;

we may not be able to overcome technological hurdles to development or a product candidate may not be capable of
producing commercial quantities at an acceptable cost or at all;

we may not be able to assemble sufficient resources to acquire or discover additional product candidates;

our product candidates may not succeed in nonclinical or clinical testing;

our potential product candidates may fail to show sufficient biosimilarity to originator molecules; and

competitors may develop alternatives that render our product candidates obsolete or less attractive or the market for
a product candidate may change such that a product candidate may not justify further development.

If any of these events occur, we may be forced to abandon our development efforts for a program or programs or we may
not be able to identify, develop or commercialize additional product candidates, which would have a material adverse effect on
our business and could potentially cause us to cease operations.

Risks Related to Our Compliance with Applicable Laws

Healthcare legislative reform measures may have a material adverse effect on our business and results of operations.

In the United States, there have been and continue to be a number of legislative initiatives to contain healthcare costs. For
example,  in  March  2010,  the  Patient  Protection  and  Affordable  Care  Act,  as  amended  by  the  Health  Care  and  Education
Reconciliation  Act,  (together  the  “ACA”),  was  passed,  which  substantially  changed  the  way  health  care  is  financed  by  both
governmental  and  private  insurers  and  significantly  impacts  the  U.S.  pharmaceutical  industry.  The  ACA,  among  other  things,
addressed  a  new  methodology  by  which  rebates  owed  by  manufacturers  under  the  Medicaid  Drug  Rebate  Program  are
calculated for drugs that are inhaled, infused, instilled, implanted or injected, increased the minimum Medicaid rebates owed by
manufacturers under the Medicaid Drug Rebate Program and extends the

49

Table of Contents

rebate  program  to  individuals  enrolled  in  Medicaid  managed  care  organizations,  added  a  provision  to  increase  the  Medicaid
rebate  for  line  extensions  or  reformulated  drugs,  establishes  annual  fees  and  taxes  on  manufacturers  of  certain  branded
prescription drugs and promoted a new Medicare Part D coverage gap discount program.

Since its enactment, there have been judicial and Congressional challenges to certain aspects of the ACA, and we expect
there  will  be  additional  challenges  and  amendments  to  the  ACA  in  the  future,  particularly  in  light  of  the  current  presidential
administration and U.S. Congress. In addition, Congress could consider subsequent legislation to replace or repeal and replace
elements of the ACA. At the end of 2017, the Tax Cuts and Jobs Act (the “Tax Act”) was enacted, which, among other things,
removes penalties for not complying with ACA’s individual mandate to carry health insurance. On December 14, 2018, a U.S.
District Court Judge in the Northern District of Texas, ruled that the individual mandate is a critical and inseverable feature of the
ACA, and therefore, because it was repealed as part of the Tax Act, the remaining provisions of the ACA are invalid as well. On
December 18, 2019, the U.S. Court of Appeals for the 5th Circuit upheld the District Court’s decision that the individual mandate
was unconstitutional but remanded the case back to the District Court to determine whether the remaining provisions of the ACA
are invalid as well. The U.S. Supreme Court is currently reviewing the case, although it is unclear how the Supreme Court will
rule. In addition, there may be other efforts to challenge, repeal or replace the ACA. At this time, the full effect that the ACA and
any subsequent changes would have on our business remains unclear.

In addition, other legislative changes have been proposed and adopted in the United States since the ACA was enacted.
On August 2, 2011, the Budget Control Act of 2011, among other things, included aggregate reductions of Medicare payments
to providers of 2% per fiscal year, which went into effect on April 1, 2013 and will stay in effect through 2030, with the exception
of  a  temporary  suspension  from  May  1,  2020  through  March  31,  2021,  unless  additional  Congressional  action  is  taken.  In
addition, on January 2, 2013, the American Taxpayer Relief Act of 2012 was signed into law, which, among other things, further
reduced Medicare payments to certain providers, including physicians, hospitals and cancer treatment centers. Recently there
has also been heightened government scrutiny over the manner in which manufacturers set prices for their approved products,
which has resulted in several Congressional inquiries and proposed and enacted legislation designed to, among other things,
reform  government  program  reimbursement  methodologies.  Individual  states  in  the  United  States  have  also  become
increasingly  active  in  passing  legislation  and  implementing  regulations  designed  to  control  pharmaceutical  product  pricing,
including  price  or  patient  reimbursement  constraints,  discounts,  restrictions  on  certain  product  access  and  marketing  cost
disclosure and transparency measures, and, in some cases, designed to encourage importation from other countries and bulk
purchasing. We expect that additional state and federal healthcare reform measures will be adopted in the future, any of which
could limit the amounts that federal and state governments will pay for healthcare products and services, which could result in
reduced demand for our product candidates or additional pricing pressures, such as a single reimbursement code for biosimilar
products.

In the E.U., similar political, economic and regulatory developments may affect our ability to profitably commercialize our
product  candidates,  if  approved.  In  addition  to  continuing  pressure  on  prices  and  cost  containment  measures,  legislative
developments at the E.U. or member state level may result in significant additional requirements or obstacles that may increase
our operating costs. The delivery of healthcare in the E.U., including the establishment and operation of health services and the
pricing and reimbursement of medicines, is almost exclusively a matter for national, rather than E.U., law and policy. National
governments and health service providers have different priorities and approaches to the delivery of health care and the pricing
and reimbursement of products in that context. In general, however, the healthcare budgetary constraints in most E.U. member
states have resulted in restrictions on the pricing and reimbursement of medicines by relevant health service providers. Coupled
with ever-increasing E.U. and national regulatory burdens on those wishing to develop and market products, this could prevent
or  delay  marketing  approval  of  our  product  candidates,  restrict  or  regulate  post-approval  activities  and  affect  our  ability  to
commercialize  our  product  candidates,  if  approved.  In  markets  outside  of  the  U.S.  and  E.U.,  reimbursement  and  healthcare
payment  systems  vary  significantly  by  country,  and  many  countries  have  instituted  price  ceilings  on  specific  products  and
therapies.

We may be subject, directly or indirectly, to federal and state healthcare laws, including fraud and abuse, false claims
and physician payment transparency laws. If we are unable to comply or have not fully complied with such laws, we
could face substantial penalties.

Our operations are directly or indirectly through our customers subject to various federal and state fraud and abuse laws,
including,  without  limitation,  the  federal  Anti-Kickback  Statute,  the  federal  False  Claims  Act  and  physician  sunshine  laws  and
regulations. These laws impact, among other things, sales, marketing and education programs. In addition, we may be subject
to patient privacy regulation by both the federal government and the states in which we conduct our business. The laws that may
affect our ability to operate include:

●

the federal Anti-Kickback Statute, which prohibits, among other things, persons from knowingly and willfully soliciting,
receiving,  offering  or  paying  remuneration,  directly  or  indirectly,  in  cash  or  in  kind,  to  induce  or  in  return  for  the
purchase,  recommendation,  order  or  furnishing  of  an  item  or  service  reimbursable,  in  whole  or  in  part,  under  a
federal healthcare

program, such as the Medicare and Medicaid programs. A person or entity does not need to have actual knowledge
of the federal Anti-Kickback Statute or specific intent to violate it to have committed a violation;

federal  civil  and  criminal  false  claims  laws,  including  the  False  Claims  Act,  which  prohibit,  among  other  things,
individuals  or  entities  from  knowingly  presenting  or  causing  to  be  presented  claims  for  payment  from  Medicare,
Medicaid or other third-party payers that are false or fraudulent and which may apply to entities that provide coding
and  billing  advice  to  customers.  In  addition,  the  government  may  assert  that  a  claim  including  items  or  services
resulting from a violation of the federal Anti-Kickback Statute constitutes a false or fraudulent claim for purposes of
the False Claims Act;

federal  civil  monetary  penalties  laws,  which  impose  civil  fines  for,  among  other  things,  the  offering  or  transfer  of
remuneration to a Medicare or state healthcare program beneficiary if the person knows or should know it is likely to
influence  the  beneficiary’s  selection  of  a  particular  provider,  practitioner,  or  supplier  of  services  reimbursable  by
Medicare or a state healthcare program, unless an exception applies;

the federal Health Insurance Portability and Accountability Act of 1996 (“HIPAA”), which created new federal criminal
statutes  that  prohibit  executing  a  scheme  to  defraud  any  healthcare  benefit  program  and  making  false  statements
relating to healthcare matters. Similar to the federal Anti-Kickback Statute, a person or entity does not need to have
actual knowledge of the statute or specific intent to violate it to have committed a violation;

federal and state consumer protection and unfair competition laws, which broadly regulate marketplace activities and
activities that potentially harm consumers;

the  federal  physician  “sunshine”  requirements  under  the  ACA,  which  requires  certain  manufacturers  of  drugs,
devices,  biologics  and  medical  supplies  to  report  annually  to  the  Centers  for  Medicare  &  Medicaid  Services
information related to payments and other transfers of value made by such manufacturers to physicians, as defined
in  the  statute,  including  their  immediate  family  members,  certain  other  healthcare  professionals  as  of  2022,  and
teaching  hospitals  and  ownership  and  investment  interests  held  by  such  physicians  and  their  immediate  family
members and applicable GPOs; and

state and foreign law equivalents of each of the above federal laws, such as anti-kickback and false claims laws that
may  apply  to  items  or  services  reimbursed  by  any  third-party  payer,  including  commercial  insurers,  state  laws  that
require pharmaceutical companies to comply with the pharmaceutical industry’s voluntary compliance guidelines and
the relevant compliance guidance promulgated by the federal government or otherwise restrict payments that may be
made to healthcare providers and other potential referral sources; and state laws that require drug manufacturers to
report information related to payments and other transfers of value to physicians and other healthcare providers or
marketing expenditures and pricing information.

Because  of  the  breadth  of  these  laws  and  the  narrowness  of  the  statutory  exceptions  and  safe  harbors  available,  it  is
possible that some of our business activities could be subject to challenge under one or more of such laws. In addition, recent
health care reform legislation has strengthened these laws.

Efforts to ensure that our operations and business arrangements with third parties will comply with applicable healthcare
laws and regulations will involve substantial costs. If we are found to be in violation of any of the laws described above or any
other governmental regulations that apply to us, we may be subject to penalties, including civil and criminal penalties, damages,
fines,  exclusion  from  participation  in  government  health  care  programs,  such  as  Medicare  and  Medicaid,  imprisonment,
additional  reporting  obligations  and  oversight  if  we  become  subject  to  a  corporate  integrity  agreement  or  other  agreement  to
resolve allegations of non-compliance with these laws and the curtailment or restructuring of our operations, any of which could
adversely affect our ability to operate our business and our results of operations. Further, defending against any such actions
can  be  costly,  time-consuming  and  may  require  significant  personnel  resources.  Therefore,  even  if  we  are  successful  in
defending against any such actions that may be brought against us, our business may be impaired.

If we participate in and then fail to comply with our reporting and payment obligations under the Medicaid Drug Rebate
Program or other governmental pricing programs in the United States, we could be subject to additional
reimbursement requirements, penalties, sanctions and fines which could have a material adverse effect on our
business, financial condition, results of operations and growth prospects.

With  the  approval  of  UDENYCA®,  we  now  participate  in  the  Medicaid  Drug  Rebate  Program,  Medicare  Coverage  Gap
Discount Program and a number of other federal and state government pricing programs in the United States in order to obtain
coverage for the

51

Table of Contents

product by certain government healthcare programs. These programs generally require us to pay rebates or provide discounts to
certain  private  purchasers  or  government  payers  in  connection  with  our  products  when  dispensed  to  beneficiaries  of  these
programs.  In  some  cases,  such  as  with  the  Medicaid  Drug  Rebate  Program,  the  rebates  are  based  on  pricing  and  rebate
calculations  that  we  report  on  a  monthly  and  quarterly  basis  to  the  government  agencies  that  administer  the  programs.  The
terms,  scope  and  complexity  of  these  government  pricing  programs  change  frequently.  We  may  also  have  reimbursement
obligations  or  be  subject  to  penalties  if  we  fail  to  provide  timely  and  accurate  information  to  the  government,  pay  the  correct
rebates or offer the correct discounted pricing. Changes to the price reporting or rebate requirements of these programs would
affect our obligations to pay rebates or offer discounts. Responding to current and future changes may increase our costs and
the complexity of compliance, will be time-consuming, and could have a material adverse effect on our results of operations.

Risks Related to Ownership of Our Common Stock

The market price of our common stock may be highly volatile, and purchasers of our common stock could incur
substantial losses.

The  market  price  of  our  common  stock  has  been  highly  volatile  since  our  Initial  Public  Offering  (“IPO”)  and  the  intraday
sales price per share has ranged from $8.05 to $38.10 per share during the period from November 6, 2014 through February 19,
2021  and  could  be  subject  to  wide  fluctuations  in  response  to  various  factors,  some  of  which  are  beyond  our  control.  These
factors include those discussed in the “Risk Factors” section of this Annual Report on Form 10-K and others such as:

adverse results or delays in preclinical or clinical studies;

any inability to obtain additional funding;

any  delay  in  filing  an  IND,  NDA,  original  BLA,  351(k)  BLA  or  other  regulatory  submission  for  any  of  our  product
candidates  and  any  adverse  development  or  perceived  adverse  development  with  respect  to  the  applicable
regulatory agency’s review of that IND, NDA, original BLA, 351(k) BLA or other regulatory submission;

the perception of limited market sizes or pricing for our product candidates;

failure to successfully develop and commercialize our product candidates;

post-marketing safety issues relating to our product candidates or biosimilars generally;

failure to maintain our existing strategic collaborations or enter into new collaborations;

failure  by  us  or  our  licensors  and  strategic  collaboration  partners  to  prosecute,  maintain  or  enforce  our  intellectual
property rights;

changes in laws or regulations applicable to our products;

any  inability  to  obtain  adequate  product  supply  for  our  product  candidates  or  the  inability  to  do  so  at  acceptable
prices;

adverse regulatory decisions;

introduction of new products, services or technologies by our competitors;

failure to meet or exceed financial projections we may provide to the public;

failure to meet or exceed the financial projections of the investment community;

the perception of the pharmaceutical industry by the public, legislatures, regulators and the investment community;

announcements  of  significant  acquisitions,  strategic  partnerships,  joint  ventures  or  capital  commitments  by  us,  our
strategic collaboration partners or our competitors;

disputes  or  other  developments  relating  to  proprietary  rights,  including  patents,  litigation  matters  and  our  ability  to
obtain patent protection for our technologies;

additions or departures of key scientific or management personnel;

lawsuits, including stockholder litigation and litigation filed by us or filed against us pertaining to patent infringement
or other violations of intellectual property rights;

the outcomes of any citizen petitions filed by parties seeking to restrict or limit the approval of biosimilar products;

if securities or industry analysts do not publish research or reports about our business or if they issue an adverse or
misleading opinion regarding our stock;

changes in the market valuations of similar companies;

general market or macroeconomic conditions;

sales of our common stock by us or our stockholders in the future;

trading volume of our common stock;

issuance of patents to third parties that could prevent our ability to commercialize our product candidates;

reductions  in  the  prices  of  originator  products  that  could  reduce  the  overall  market  opportunity  for  our  product
candidates intended as biosimilars to such originator products; and

changes  in  biosimilar  regulatory  requirements  that  could  make  it  more  difficult  for  us  to  develop  our  product
candidates.

In addition, biopharmaceutical companies in particular have experienced extreme price and volume fluctuations that have
often been unrelated or disproportionate to the operating performance of these companies. Broad market and industry factors
may negatively affect the market price of our common stock, regardless of our actual operating performance.

Our principal stockholders and management own a significant percentage of our stock and will be able to exert
significant control over matters subject to stockholder approval.

As of December 31, 2020, our executive officers, directors, five percent stockholders and their affiliates beneficially owned
approximately  62.6%  of  our  voting  stock  (assuming  no  exercise  of  outstanding  options  or  conversion  of  our  outstanding
convertible notes). These stockholders have the ability to influence us through their ownership positions, which may prevent or
discourage unsolicited acquisition proposals or offers for our common stock that you may believe are in your best interest as one
of our stockholders.

Sales of a substantial number of shares of our common stock in the public market could cause our stock price to fall.

If  our  existing  stockholders  sell  or  indicate  an  intention  to  sell  substantial  amounts  of  our  common  stock  in  the  public
market after the lock-up and other legal restrictions on resale lapse, the market price of our common stock could decline. As of
December 31, 2020, there were approximately 72.5 million shares of common stock outstanding. Of these shares, the shares of
our common stock sold in our IPO, our underwritten follow-on offering, pursuant to our at-the-market equity offering program and
in private placement transactions are currently freely tradable, without restriction (except as otherwise applicable), in the public
market.

In  addition,  as  of  December  31,  2020,  approximately  23.3  million  shares  of  common  stock  that  are  either  subject  to
outstanding options and restricted stock units or reserved for future issuance under our equity incentive plans were eligible or
may  become  eligible  for  sale  in  the  public  market  to  the  extent  permitted  by  the  provisions  of  various  vesting  schedules  and
Rule 144 and Rule 701 under the Securities Act. If these additional shares of common stock are sold or if it is perceived that
they will be sold in the public market, the market price of our common stock could decline.

Future sales and issuances of our common stock or rights to purchase common stock, including pursuant to our
equity incentive plans and convertible notes, could result in additional dilution of the percentage ownership of our
stockholders and could cause our stock price to fall.

We  have  needed  and  anticipate  we  will  need  additional  capital  in  the  future  to  continue  our  planned  operations.  To  the
extent that we raise additional capital by issuing equity securities, our stockholders may experience substantial dilution. Similar
to  prior  financing  transactions,  we  may  sell  common  stock,  convertible  securities  or  other  equity  securities  in  one  or  more
transactions at prices and in a manner we determine from time to time. If we sell common stock, convertible securities or other
equity securities in more than one transaction, investors may be materially diluted by subsequent sales. These sales may also
result in material dilution to our existing stockholders, and new investors could gain rights superior to our existing stockholders.
Any future debt financing may involve covenants that restrict our operations, including, among other restrictions, limitations on
our ability to incur liens or additional debt, pay dividends, redeem our stock, make certain investments, and engage in certain
merger, consolidation, or asset sale transactions. In addition, if we raise additional funds through licensing arrangements, it may
be necessary to grant potentially valuable rights to our product candidates or grant licenses on terms that are not favorable to
us.

Pursuant to our 2014 Equity Incentive Award Plan (the “2014 Plan”), our management is authorized to grant stock options
and other equity-based awards to our employees, directors and consultants. Under the 2014 Plan, the number of shares of our
common stock initially reserved for issuance is 2,300,000 plus the number of shares remaining available for future awards under
the 2010 Plan. The number of shares available for future grant under the 2014 Plan will be increased by (i) the number of shares
pursuant  to  outstanding  awards  under  the  2010  Plan  that  are  forfeited  or  lapse  unexercised  and  which  following  the  effective
date are not issued under the 2010 Plan and (ii) an annual increase on the first day of each fiscal year beginning in 2015 and
ending in 2024, equal to 4% of the shares of stock outstanding as of the last day of the preceding fiscal year, or such smaller
number of shares as determined by our board of directors. Pursuant to our 2014 Employee Stock Purchase Plan (“2014 ESPP”),
eligible  employees  are  able  to  acquire  shares  of  our  common  stock  at  a  discount  to  the  prevailing  market  price,  and  an
aggregate  of  320,000  shares  are  initially  available  for  issuance  under  the  2014  ESPP.  The  number  of  shares  available  for
issuance under the 2014 ESPP will automatically increase on the first day of each fiscal year beginning in 2015 and ending in
2024, equal to 1% of the shares of common stock outstanding on the last day of the immediately preceding fiscal year or such
smaller  number  of  shares  as  determined  by  our  board  of  directors.  If  our  board  of  directors  elects  to  increase  the  number  of
shares available for future grant under the 2014 Plan or the 2014 ESPP, our stockholders may experience additional dilution,
which could cause our stock price to fall. Pursuant to our 2016 Employment Commencement Incentive Plan (the “2016 Plan”),
our management is authorized to grant stock options and other equity-based awards to our new employees. The 2016 Plan is
designed to comply with the inducement exemption contained in Nasdaq’s Rule 5635(c)(4), which provides for the grant of non-
qualified stock options, restricted stock units, restricted stock awards, performance awards, dividend equivalents, deferred stock
awards, deferred stock units, stock payment and stock appreciation rights to a person not previously an employee or director, or
following a bona fide period of non-employment, as an inducement material to the individual’s entering into employment with us.
As of December 31, 2020, we reserved for future issuance under the 2016 Plan a total of 0.2 million shares of common stock for
new employees. The 2016 Plan does not provide for any annual increases in the number of shares available.

In February 2016, we issued and sold $100.0 million aggregate principal amount of our 8.2% senior convertible notes due
March 2022 (the “2022 Convertible Notes”). The holders may convert their 2022 Convertible Notes at their option at any time
prior  to  the  close  of  business  on  the  business  day  immediately  preceding  March  31,  2022.  Upon  conversion  of  the  2022
Convertible Notes by a holder, the holder will receive shares of our common stock, together, if applicable, with cash in lieu of any
fractional share. The initial conversion rate is 44.7387 shares of common stock per $1,000 principal amount of convertible notes,
which  is  equivalent  to  an  initial  conversion  price  of  approximately  $22.35  per  share,  and  is  subject  to  adjustment  in  certain
events.

In April 2020, we issued and sold $230.0 million aggregate principal amount of our 1.5% senior convertible notes due April
2026 (the “2026 Convertible Notes”). The holders may convert their 2026 Convertible Notes at their option at any time prior to
the  close  of  business  on  the  second  scheduled  trading  day  immediately  before  April  15,  2016.  Upon  conversion  of  the  2026
Convertible Notes by a holder, the holder will receive shares of our common stock, together, if applicable, with cash in lieu of any
fractional share. The initial conversion rate is 51.9224 shares of common stock per $1,000 principal amount of convertible notes,
which  is  equivalent  to  an  initial  conversion  price  of  approximately  $19.26  per  share,  and  is  subject  to  adjustment  in  certain
events.

We do not intend to pay dividends on our common stock so any returns will be limited to the value of our stock.

We have never declared or paid any cash dividends on our common stock. We currently anticipate that we will retain future
earnings  for  the  development,  operation  and  expansion  of  our  business  and  do  not  anticipate  declaring  or  paying  any  cash
dividends for the foreseeable future. Any return to stockholders will therefore be limited to the appreciation of their stock.

Provisions in our amended and restated certificate of incorporation and amended and restated bylaws, as well as
provisions of Delaware law, could make it more difficult for a third party to acquire us or increase the cost of acquiring
us, even if doing so would benefit our stockholders or remove our current management.

Our amended and restated certificate of incorporation, amended and restated bylaws and Delaware law contain provisions
that may have the effect of delaying or preventing a change in control of us or changes in our management. Our amended and
restated certificate of incorporation and bylaws include provisions that:

●

●

●

●

●

●

●

●

●

●

authorize “blank check” preferred stock, which could be issued by our board of directors without stockholder approval
and may contain voting, liquidation, dividend and other rights superior to our common stock;

create a classified board of directors whose members serve staggered three-year terms;

specify  that  special  meetings  of  our  stockholders  can  be  called  only  by  our  corporate  secretary  pursuant  to  a
resolution adopted by a majority of our board of directors;

prohibit stockholder action by written consent;

establish  an  advance  notice  procedure  for  stockholder  approvals  to  be  brought  before  an  annual  meeting  of  our
stockholders, including proposed nominations of persons for election to our board of directors other than nominations
made by or at the direction of the board of directors or a committee of the board of directors;

provide that our directors may be removed only for cause or without cause by the holders of 66 2/3% of the voting
power of all then outstanding shares of voting stock;

provide  that  vacancies  on  our  board  of  directors  may  be  filled  only  by  a  majority  of  directors  then  in  office,  even
though less than a quorum;

specify that no stockholder is permitted to cumulate votes at any election of directors;

expressly authorize our board of directors to modify, alter or repeal our amended and restated bylaws; and

require  holders  of  66  2/3%  of  the  voting  power  of  all  then  outstanding  shares  of  voting  stock  to  amend  specified
provisions of our amended and restated certificate of incorporation except for the provision making it possible for our
board of directors to issue “blank check” preferred stock, and amended and restated bylaws.

These provisions, alone or together, could delay, deter or prevent hostile takeovers and changes in control or changes in

our management.

In addition, because we are incorporated in Delaware, we are governed by the provisions of Section 203 of the Delaware
General  Corporation  Law,  which  limits  the  ability  of  stockholders  owning  in  excess  of  15%  of  our  outstanding  voting  stock  to
merge or combine with us.

Any provision of our amended and restated certificate of incorporation or amended and restated bylaws or Delaware law
that  has  the  effect  of  delaying  or  deterring  a  change  in  control  could  limit  the  opportunity  for  our  stockholders  to  receive  a
premium  for  their  shares  of  our  common  stock  and  could  also  affect  the  price  that  some  investors  are  willing  to  pay  for  our
common stock.

General Risk Factors

Our reliance on third parties requires us to share our trade secrets, which increases the possibility that a competitor
will discover them or that our trade secrets will be misappropriated or disclosed.

55

Table of Contents

Because we rely on third parties to develop and manufacture our product candidates, we must, at times, share trade
secrets with them. We seek to protect our proprietary technology in part by entering into confidentiality agreements and, if
applicable, material transfer agreements, collaborative research agreements, consulting agreements or other similar agreements
with our collaboration partners, advisors, employees and consultants prior to beginning research or disclosing proprietary
information. These agreements typically limit the rights of the third parties to use or disclose our confidential information, such as
trade secrets. Despite the contractual provisions employed when working with third parties, the need to share trade secrets and
other confidential information increases the risk that such trade secrets become known by our competitors, are inadvertently
incorporated into the technology of others or are disclosed or used in violation of these agreements. Given that our proprietary
position is based, in part, on our know-how and trade secrets, a competitor’s discovery of our trade secrets or other
unauthorized use or disclosure would impair our competitive position and may have a material adverse effect on our business.

We or the third parties upon whom we depend may be adversely affected by earthquakes or other natural disasters and
our business continuity and disaster recovery plans may not adequately protect us from a serious disaster.

Our corporate headquarters and laboratory are located in the San Francisco Bay Area and in Southern California
(Camarillo), respectively. These locations have in the past experienced severe earthquakes and other natural disasters. We do
not carry earthquake insurance. Earthquakes or other natural disasters could severely disrupt our operations or those of our
collaboration partners and have a material adverse effect on our business, results of operations, financial condition and
prospects. If a natural disaster, power outage or other event occurred that prevented us from using all or a significant portion of
our headquarters, that damaged critical infrastructure (such as the manufacturing facilities of our third-party contract
manufacturers) or that otherwise disrupted operations, it may be difficult or, in certain cases, impossible for us to continue our
business for a substantial period of time. The disaster recovery and business continuity plans we have in place currently are
limited and are unlikely to prove adequate in the event of a serious disaster or similar event. We may incur substantial expenses
as a result of the limited nature of our disaster recovery and business continuity plans, which, particularly when taken together
with our lack of earthquake insurance, could have a material adverse effect on our business.

So called “submarine” patents may be granted to our competitors that may significantly alter our launch timing
expectations, reduce our projected market size, cause us to modify our product or process or block us from the market
altogether.

The term “submarine” patent has been used in the pharmaceutical industry and in other industries to denote a patent

issuing from an application that was not published, publically known or available prior to its grant. Submarine patents add
substantial risk and uncertainty to our business. Submarine patents may issue to our competitors covering our biosimilar product
candidates or our pipeline candidates and thereby cause significant market entry delay, defeat our ability to market our products
or cause us to abandon development and/or commercialization of a molecule.

Examples of submarine patents include Brockhaus, et al., U.S. patents 8,063,182 and 8,163,522 (controlled by Amgen),

which are directed to the fusion protein in Enbrel. On July 1, 2020, the U.S. Court of Appeals for the Federal Circuit issued a
decision that affirmed the lower court’s decision upholding the validity of these patents. As a result, we discontinued the
development of CHS-0214 (our etanercept (Enbrel®) biosimilar candidate).

The issuance of one or more submarine patents may harm our business by causing substantial delays in our ability to

introduce a biosimilar candidate into the United States market.

We may not identify relevant patents or may incorrectly interpret the relevance, scope or expiration of a patent, which
might adversely affect our ability to develop and market our products.

We cannot guarantee that any of our patent searches or analyses, including but not limited to the identification of relevant
patents, the scope of patent claims or the expiration of relevant patents, are complete and thorough, nor can we be certain that
we have identified each and every patent and pending application in the United States and abroad that is relevant to or
necessary for the commercialization of our product candidates in any jurisdiction.

The scope of a patent claim is determined by an interpretation of the law, the written disclosure in a patent and the
patent’s prosecution history. Our interpretation of the relevance or the scope of a patent or a pending application may be
incorrect, which may negatively impact our ability to market our products or pipeline molecules. We may incorrectly determine
that our products are not covered by a third party patent.

56

Table of Contents

Many patents may cover a marketed product, including but not limited to the composition of the product, methods of use,
formulations, cell line constructs, vectors, growth media, production processes and purification processes. The identification of
all patents and their expiration dates relevant to the production and sale of an originator product is extraordinarily complex and
requires sophisticated legal knowledge in the relevant jurisdiction. It may be impossible to identify all patents in all jurisdictions
relevant to a marketed product. Our determination of the expiration date of any patent in the United States or abroad that we
consider relevant may be incorrect, which may negatively impact our ability to develop and market our products.

Our failure to identify and correctly interpret relevant patents may negatively impact our ability to develop and market
our products.

If we are unable to obtain and maintain effective patent rights for our product candidates or any future product candidates,

we may not be able to prevent competitors from using technologies we consider important in our successful development and
commercialization of our product candidates, resulting in loss of any potential competitive advantage our patents may have
otherwise afforded us.

While our principal focus in matters relating to intellectual property is to avoid infringing the valid and enforceable rights of

third parties, we also rely upon a combination of patents, trade secret protection and confidentiality agreements to protect our
own intellectual property related to our product candidates and development programs. Our ability to enjoy any competitive
advantages afforded by our own intellectual property depends in large part on our ability to obtain and maintain patents and
other intellectual property protection in the United States and in other countries with respect to various proprietary elements of
our product candidates, such as, for example, our product formulations and processes for manufacturing our products and our
ability to maintain and control the confidentiality of our trade secrets and confidential information critical to our business.

We have sought to protect our proprietary position by filing patent applications in the United States and abroad related to
our products that are important to our business. This process is expensive and time consuming, and we may not be able to file
and prosecute all necessary or desirable patent applications at a reasonable cost or in a timely manner. It is also possible that
we will fail to identify patentable aspects of our research and development output before it is too late to obtain patent protection.
There is no guarantee that any patent application we file will result in an issued patent having claims that protect our products.
Additionally, while the basic requirements for patentability are similar across jurisdictions, each jurisdiction has its own specific
requirements for patentability. We cannot guarantee that we will obtain identical or similar patent protection covering our
products in all jurisdictions where we file patent applications.

The patent positions of biopharmaceutical companies generally are highly uncertain and involve complex legal and factual

questions. As a result, the patent applications that we own or license may fail to result in issued patents with claims that cover
our product candidates in the United States or in other foreign countries for many reasons. There is no assurance that all
potentially relevant prior art relating to our patents and patent applications has been found, considered or cited during patent
prosecution, which can be used to invalidate a patent or prevent a patent from issuing from a pending patent application. Even if
patents do successfully issue, and even if such patents cover our product candidates, third parties may challenge their validity,
enforceability or scope, which may result in such patent claims being narrowed, found unenforceable or invalidated. Our patents
and patent applications, even if they are unchallenged, may not adequately protect our intellectual property, provide exclusivity
for our product candidates or prevent others from designing around our claims. Any of these outcomes could impair our ability to
prevent competitors from using the technologies claimed in any patents issued to us, which may have an adverse impact on our
business.

In addition, changes to U.S. patent laws provide additional procedures for third parties to challenge the validity of issued
patents based on patent applications filed after March 15, 2013. If the breadth or strength of protection provided by the patents
and patent applications we hold or pursue with respect to our current or future product candidates is challenged, then it could
threaten our ability to prevent competitive products using our proprietary technology. Further, because patent applications in the
United States and most other countries are confidential for a period of time, typically for 18 months after filing, we cannot be
certain that we were the first to either (i) file any patent application related to our product candidates or (ii) invent any of the
inventions claimed in our patents or patent applications. Furthermore, for applications filed before March 16, 2013 or patents
issuing from such applications, an interference proceeding can be provoked by a third party or instituted by the USPTO to
determine who was the first to invent any of the subject matter covered by the patent claims of our applications and patents. As
of March 16, 2013, the U.S. transitioned to a “first-to-file” system for deciding which party should be granted a patent when two
or more patent applications claiming the same invention are filed by different parties. A third party that files a patent application
in the USPTO before we do, could therefore be awarded a patent

57

Table of Contents

covering an invention of ours even if we had made the invention before it was made by the third party. The change to “first-to-
file” from ”first-to-invent” is one of the changes to the patent laws of the U.S. resulting from the Leahy-Smith America Invents Act
(the “Leahy-Smith Act”), signed into law on September 16, 2011. Among some of the other significant changes to the patent
laws are changes that limit where a patentee may file a patent infringement suit and provide opportunities for third parties to
challenge any issued patent in the USPTO. It is not yet clear what, if any, impact the Leahy-Smith Act will have on the operation
of our business. However, the Leahy-Smith Act and its implementation could increase the uncertainties and costs surrounding
the prosecution of our patent applications and the enforcement or defense of our issued patents, all of which could have a
material adverse effect on our business and financial condition.

Patents granted by the European Patent Office may be opposed by any person within nine months from the publication of

their grant and, in addition, may be challenged before national courts at any time. If the breadth or strength of protection
provided by the patents and patent applications we hold, license or pursue with respect to our product candidates is threatened,
it could threaten our ability to prevent third parties from using the same technologies that we use in our product candidates.

We have issued patents and have filed patent applications, which are currently pending, covering various aspects of our

product candidates. We cannot offer any assurances about which, if any, patents will issue, the breadth of any such patent or
whether any issued patents will be found invalid and unenforceable or will be threatened or infringed by third parties. Any
successful actions by third parties to challenge the validity or enforceability of any patents, which may issue to us could deprive
us of the ability to prevent others from using the technologies claimed in such issued patents. Further, if we encounter delays in
regulatory approvals, the period of time during which we could market a product candidate under patent protection could be
reduced.

While our business is based primarily on the timing of our biosimilar product launches to occur after the expiration of

relevant patents and on avoiding infringing valid and enforceable rights of third parties, we have filed a number of patent
applications seeking patents that cover various proprietary elements of our product candidates when we have believed securing
such patents may afford a competitive advantage. Our patent portfolio includes pending patent applications and issued patents,
in the United States and globally, covering our biosimilar product candidates and methods of making them. We cannot guarantee
that our proprietary technologies will avoid infringement of third party patents. Moreover, because competitors may be able to
develop their own proprietary technologies, it is uncertain whether any of our issued patents or pending patent applications
directed to etanercept and adalimumab would cover the etanercept and adalimumab products of any competitors. The product
and patent landscape is highly uncertain and we cannot predict whether our patent filings will afford us a competitive advantage
against third parties or if our etanercept and adalimumab products will avoid infringement of third party patents.

We do not consider it necessary for us or our competitors to obtain or maintain a proprietary patent position in order to

engage in the business of biosimilar development and commercialization. Hence, while our ability to secure patent coverage on
our own proprietary developments may improve our competitive position with respect to the product candidates we intend to
commercialize, we do not view our own patent filings as a necessary or essential requirement for conducting our business nor
do we rely on our own patent filings or the potential for any commercial advantage they may provide us as a basis for our
success.

Obtaining and maintaining our patent protection depends on compliance with various procedural requirements,
document submissions, fee payment and other requirements imposed by governmental patent agencies. Our patent
protection could be reduced or eliminated for non-compliance with these requirements.

The USPTO and various foreign governmental patent agencies require compliance with a number of procedural,

documentary, fee payment and other provisions during the patent process. In many cases, an inadvertent lapse can be cured by
payment of a late fee or by other means in accordance with the applicable rules. However, there are situations in which
noncompliance can result in abandonment or lapse of a patent or patent application, resulting in partial or complete loss of
patent rights in the relevant jurisdiction. In such an event, competitors might be able to enter the market earlier than would
otherwise have been the case.

We may not be able to protect our intellectual property rights throughout the world.

Filing, prosecuting, defending and enforcing patents on product candidates in all countries throughout the world would be
prohibitively expensive, and our intellectual property rights in some countries outside the U.S. can be less extensive than those
in the United States. In addition, the laws of some foreign countries do not protect intellectual property rights to the same extent
as federal and state laws in the United States. Further, licensing partners may choose not to file patent applications in certain
jurisdictions in which

58

Table of Contents

we may obtain commercial rights, thereby precluding the possibility of later obtaining patent protection in these countries.
Consequently, we may not be able to prevent third parties from practicing our inventions in all countries outside the U.S. or
importing products made using our inventions into the U.S. or other jurisdictions. Competitors may use our technologies in
jurisdictions where we have not obtained patent protection to develop their own products and may also export infringing products
to territories where we have patent protection, but the ability to enforce our patents is not as strong as that in the United States.
These products may compete with our products and our patents or other intellectual property rights may not be effective or
sufficient to prevent them from competing.

Many companies have encountered significant problems in protecting and defending intellectual property rights in foreign

jurisdictions. The legal systems of certain countries, particularly certain developing countries, do not favor the enforcement of
patents, trade secrets and other intellectual property protection, which could make it difficult for us to stop the infringement of our
patents or marketing of competing products in violation of our proprietary rights generally. Proceedings to enforce our patent
rights in foreign jurisdictions, whether or not successful, could result in substantial costs and divert our efforts and attention from
other aspects of our business, could put our patents at risk of being invalidated or interpreted narrowly and our patent
applications at risk of not issuing and could provoke third parties to assert claims against us. We may not prevail in any lawsuits
that we initiate and the damages or other remedies awarded, if any, may not be commercially meaningful. Governments of
foreign countries may force us to license our patents to third parties on terms that are not commercially reasonable or
acceptable to us. Accordingly, our efforts to enforce our intellectual property rights around the world may be inadequate to obtain
a significant commercial advantage from the intellectual property that we develop or license.

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

As is the case with other biopharmaceutical companies, our success is heavily dependent on intellectual property,
particularly patents. Obtaining and enforcing patents in the biopharmaceutical industry involves both technological and legal
complexity. Therefore, obtaining and enforcing biopharmaceutical patents is costly, time consuming and inherently uncertain. In
addition, the U.S. has recently enacted and is currently implementing wide-ranging patent reform legislation.

In addition to increasing uncertainty with regard to our ability to obtain patents in the future, this combination of events has

created uncertainty with respect to the value of patents, once obtained. Depending on future actions by the U.S. Congress, the
Federal Courts and the USPTO, the laws and regulations governing patents could change in unpredictable ways that would
weaken our ability to obtain new patents or to enforce our existing patents and patents that we might obtain in the future.

If we are unable to maintain effective (non-patent) proprietary rights for our product candidates or any future product
candidates, we may not be able to compete effectively in our markets.

While we have filed patent applications to protect certain aspects of our own proprietary formulation and process
developments, we also rely on trade secret protection and confidentiality agreements to protect proprietary scientific, business
and technical information and know-how that is not or may not be patentable or that we elect not to patent. However, confidential
information and trade secrets can be difficult to protect. Moreover, the information embodied in our trade secrets and confidential
information may be independently and legitimately developed or discovered by third parties without any improper use of or
reference to information or trade secrets. We seek to protect the scientific, technical and business information supporting our
operations, as well as the confidential information relating specifically to our product candidates by entering into confidentiality
agreements with parties to whom we need to disclose our confidential information, for example, our employees, consultants,
scientific advisors, board members, contractors, potential collaborators and investors. However, we cannot be certain that such
agreements have been entered into with all relevant parties. We also seek to preserve the integrity and confidentiality of our
data and trade secrets by maintaining physical security of our premises and physical and electronic security of our information
technology systems, but it is possible that these security measures could be breached. While we have confidence in these
individuals, organizations and systems, agreements or security measures may be breached, and we may not have adequate
remedies for any breach. Our confidential information and trade secrets thus may become known by our competitors in ways we
cannot prove or remedy.

Although we expect all of our employees and consultants to assign their inventions to us, and all of our employees,
consultants, advisors and any third parties who have access to our proprietary know-how, information or technology to enter into
confidentiality agreements, we cannot provide any assurances that all such agreements have been duly executed. We cannot
guarantee that our trade secrets and other confidential proprietary information will not be disclosed or that competitors will not
otherwise gain access to our trade secrets or independently develop substantially equivalent information and techniques. For
example, any of these parties may

59

Table of Contents

breach the agreements and disclose our proprietary information, including our trade secrets, and we may not be able to obtain
adequate remedies for such breaches. Misappropriation or unauthorized disclosure of our trade secrets could impair our
competitive position and may have a material adverse effect on our business. Additionally, if the steps taken to maintain our
trade secrets are deemed inadequate, we may have insufficient recourse against third parties for misappropriating the trade
secret. We cannot guarantee that our employees, former employees or consultants will not file patent applications claiming our
inventions. Because of the “first-to-file” laws in the United States and the EU, such unauthorized patent application filings may
defeat our attempts to obtain patents on our own inventions.

We may be subject to claims challenging the inventorship of our patent filings and other intellectual property.

Although we are not currently aware of any claims challenging the inventorship of our patent applications or ownership of

our intellectual property, we may in the future be subject to claims that former employees, collaborators or other third parties
have an interest in our patent applications or patents we may be granted or other intellectual property as an inventor or co-
inventor. For example, we may have inventorship or ownership disputes arise from conflicting obligations of consultants or
others who are involved in developing our product candidates. Litigation may be necessary to defend against these and other
claims challenging inventorship or ownership. If we fail in defending any such claims, in addition to paying monetary damages,
we may lose valuable intellectual property rights, such as exclusive ownership of or right to use valuable intellectual property.
Such an outcome could have a material adverse effect on our business. Even if we are successful in defending against such
claims, litigation could result in substantial costs and be a distraction to management and other employees.

We incur significant increased costs as a result of operating as a public company, and our management is required to
devote substantial time to compliance initiatives. We may fail to comply with the rules that apply to public companies,
including Section 404 of the Sarbanes-Oxley Act of 2002, which could result in sanctions or other penalties that would
harm our business.

We incur significant legal, accounting and other expenses as a public company, including costs resulting from public

company reporting obligations under the Securities Exchange Act of 1934, as amended (the “Exchange Act”), and regulations
regarding corporate governance practices. The listing requirements of The Nasdaq Global Market require that we satisfy certain
corporate governance requirements relating to director independence, distributing annual and interim reports, stockholder
meetings, approvals and voting, soliciting proxies, conflicts of interest and a code of conduct. Our management and other
personnel must devote a substantial amount of time to ensure that we maintain compliance with all of these requirements.
Moreover, the reporting requirements, rules and regulations have increased our legal and financial compliance costs and make
some activities more time consuming and costly. Any changes we have made, and may make in the future to comply with these
obligations may not be sufficient to allow us to satisfy our obligations as a public company on a timely basis, or at all. These
reporting requirements, rules and regulations, coupled with the increase in potential litigation exposure associated with being a
public company, may also make it more difficult for us to attract and retain qualified persons to serve on our board of directors or
board committees or to serve as executive officers, or to obtain certain types of insurance, including directors’ and officers’
insurance, on acceptable terms.

We are subject to Section 404 of The Sarbanes-Oxley Act of 2002 (“Section 404”), and the related rules of the Securities

and Exchange Commission (“SEC”), which generally require our management and independent registered public accounting
firm to report on the effectiveness of our internal control over financial reporting. During the course of our review and testing, we
may identify deficiencies and be unable to remediate them before we must provide the required reports. Furthermore, if we have
a material weakness in our internal controls over financial reporting, we may not detect errors on a timely basis and our financial
statements may be materially misstated. We or our independent registered public accounting firm may not be able to conclude
on an ongoing basis that we have effective internal control over financial reporting, which could harm our operating results,
cause investors to lose confidence in our reported financial information and cause the trading price of our stock to fall. In
addition, as a public company we are required to file accurate and timely quarterly and annual reports with the SEC under the
Exchange Act. Any failure to report our financial results on an accurate and timely basis could result in sanctions, lawsuits,
delisting of our shares from The Nasdaq Global Market or other adverse consequences that would materially harm our business.

Stockholder activism, the current political environment and the current high level of government intervention and
regulatory reform may also lead to substantial new regulations and disclosure obligations, which may lead to additional
compliance costs and impact the manner in which we operate our business in ways we cannot currently anticipate. Our
management and other personnel will need to devote a substantial amount of time to these compliance initiatives. Moreover,
these rules and regulations will increase our legal and financial compliance costs and will make some activities more time
consuming and costly. For example, we expect these rules

60

Table of Contents

and regulations to make it more difficult and more expensive for us to obtain director and officer liability insurance and we may
be required to incur substantial costs to maintain our current levels of such coverage.

Our internal computer systems, or those used by our third-party CROs or other contractors or consultants, may fail or
suffer security breaches.

Despite the implementation of security measures, our internal computer, server, and other information technology systems
as well as those of our third-party collaborators, consultants, contractors, suppliers, and service providers, may be vulnerable to
damage from physical or electronic break-ins, computer viruses, “phishing” attacks, malware, ransomware, denial of service and
other cyber-attacks or disruptive incidents that could result in unauthorized access to, use or disclosure of, corruption of, or loss
of sensitive, and/ or proprietary data, including health-related information or other personal information, and could subject us to
significant liabilities and regulatory and enforcement actions, and reputational damage. If we or any of our third-party
collaborators were to experience any material failure or security breach, it could result in a material disruption of our
development programs, reputation, and business operations. For example, the loss of clinical study data from completed or
ongoing clinical studies could result in delays in any regulatory approval or clearance efforts and significantly increase our costs
to recover or reproduce the data, and subsequently commercialize the product. If we or our third-party collaborators,
consultants, contractors, suppliers, or service providers were to suffer an attack or breach, for example, that resulted in the
unauthorized access to or use or disclosure of personal information, including health-related information, we may have to notify
individuals, collaborators, government authorities, and the media, and may be subject to investigations, civil penalties,
administrative and enforcement actions, and litigation, any of which could harm our business and reputation. Likewise, we rely
on our third-party CROs and other third parties to conduct clinical studies, and similar events relating to their computer systems
could also have a material adverse effect on our business. The COVID-19 pandemic is generally increasing the attack surface
available to criminals, as more companies and individuals work online and work remotely, and as such, the risk of a
cybersecurity incident potentially occurring, and our investment in risk mitigations against such an incident, is increasing. For
example, there has been an increase in phishing and spam emails as well as social engineering attempts from “hackers” hoping
to use the recent COVID-19 pandemic to their advantage. To the extent that any disruption or security breach were to result in a
loss of, or damage to, our data or systems, or inappropriate or unauthorized access to or disclosure or use of confidential,
proprietary, or other sensitive, personal information, including health-related information, we could incur liability and suffer
reputational harm, and the development and commercialization of our products could be delayed. Our insurance policies may
not be adequate to compensate us for the potential losses arising from such disruptions, failure, or security breach. In addition,
such insurance may not be available to us in the future on economically reasonable terms, or at all. Further, our insurance may
not cover all claims made against us and defending a suit, regardless of its merit, could be costly, divert management attention,
and harm our reputation.

We are subject to governmental regulation and other legal obligations related to privacy, data protection and
information security. Compliance with these requirements could result in additional costs and liabilities to us or inhibit
our ability to collect and process data, and the failure to comply with such requirements could have a material adverse
effect on our business, financial condition or results of operations.

Privacy and data security have become significant issues in the United States, E.U. and in many other jurisdictions where

we may in the future conduct our operations. As we receive, collect, process, use and store personal and confidential data, we
may be subject to diverse laws and regulations relating to data privacy and security, including, in the United States, HIPAA and
CCPA (defined below), and, in the E.U. and the EEA, Regulation 2016/679, known as the General Data Protection Regulation
(“GDPR”). Compliance with these privacy and data security requirements is rigorous and time-intensive and may increase our
cost of doing business, and despite those efforts, there is a risk that we may be subject to fines and penalties, litigation and
reputational harm, which could materially and adversely affect our business, financial condition and results of operations.

In the United States, we and our partners may be subject to numerous federal and state laws and regulations, including
state data breach notification laws, state health information privacy laws, and federal and state consumer protection laws and
regulations, that govern the collection, use, disclosure, and protection of health-related and other personal information could
apply to our operations or the operations of our partners. In addition, we may obtain health information from third parties
(including research institutions from which we obtain clinical trial data) that are subject to privacy and security requirements
under the Health Insurance Portability and Accountability Act of 1996, as amended, or HIPAA. Depending on the facts and
circumstances, we could be subject to criminal penalties if we knowingly obtain, use, or disclose individually identifiable health
information maintained by a HIPAA-covered entity in a manner that is not authorized or permitted by HIPAA.

61

Table of Contents

Even when HIPAA does not apply, according to the Federal Trade Commission (“FTC”), failing to take appropriate steps to
keep consumers’ personal information secure constitutes unfair acts or practices in or affecting commerce in violation of Section
5(a) of the Federal Trade Commission Act. The FTC expects a company’s data security measures to be reasonable and
appropriate in light of the sensitivity and volume of consumer information it holds, the size and complexity of its business, and
the cost of available tools to improve security and reduce vulnerabilities. Individually identifiable health information is considered
sensitive data that merits stronger safeguards.

In addition, state laws govern the privacy and security of health information in certain circumstances, many of which differ

from each other in significant ways and may not have the same requirements, thus complicating compliance efforts. By way of
example, California enacted the California Consumer Privacy Act (the “CCPA”) on June 28, 2018, which went into effect on
January 1, 2020. The CCPA creates individual privacy rights for California consumers and increases the privacy and security
obligations of entities handling certain personal information. The CCPA provides for civil penalties for violations, as well as a
private right of action for data breaches that is expected to increase data breach litigation. Further, the CPRA recently passed in
California, which will impose additional data protection obligations on covered businesses, including additional consumer rights
processes, limitations on data uses, new audit requirements for higher risk data, and opt outs for certain uses of sensitive data.
It will also create a new California data protection agency authorized to issue substantive regulations and could result in
increased privacy and information security enforcement. The majority of the provisions will go into effect on January 1, 2023, and
additional compliance investment and potential business process changes may be required. The CCPA and the CPRA may
increase our compliance costs and potential liability, and many similar laws have been proposed at the federal level and in other
states.

In addition, the regulatory framework for the receipt, collection, processing, use, safeguarding, sharing and transfer of

personal and confidential data is rapidly evolving and is likely to remain uncertain for the foreseeable future as new global
privacy rules are being enacted and existing ones are being updated and strengthened. For example, on May 25, 2018, the
GDPR took effect. The GDPR is applicable in each EEA member state and applies to companies established in the EEA as well
as companies that collect and use personal data to offer goods or services to, or monitor the behavior of, individuals in the EEA,
including, for example, through the conduct of clinical trials. GDPR introduces more stringent data protection obligations for
processors and controllers of personal data. Among other things, the GDPR requires the establishment of a lawful basis for the
processing of data, includes requirements relating to the consent of the individuals to whom the personal data relates, including
detailed notices for clinical trial subjects and investigators, as well as requirements regarding the security of personal data and
notification of data processing obligations or security incidents to appropriate data protection authorities or data subjects. Recent
legal developments in Europe have created complexity and uncertainty regarding transfers of personal data from the EEA to the
United States. For example, on July 16, 2020, the Court of Justice of the European Union (“CJEU”) invalidated the EU-US
Privacy Shield Framework (“Privacy Shield”) under which personal data could be transferred from the EEA to United States
entities that had self-certified under the Privacy Shield scheme. While the CJEU upheld the adequacy of the standard
contractual clauses (a standard form of contract approved by the European Commission as an adequate personal data transfer
mechanism, and potential alternative to the Privacy Shield), it made clear that reliance on them alone may not necessarily be
sufficient in all circumstances. Use of the standard contractual clauses must now be assessed on a case-by-case basis taking
into account the legal regime applicable in the destination country, in particular applicable surveillance laws and rights of
individuals and additional measures and/or contractual provisions may need to be put in place, however, the nature of these
additional measures is currently uncertain. Penalties and fines for failure to comply with GDPR are significant, including fines of
up to €20 million or 4% of total worldwide annual turnover, whichever is higher.

Additionally, as of January 1, 2021, we have to comply with the GDPR and the GDPR as implemented in the United
Kingdom, each regime having the ability to fine up to the greater of €20 million/ £17.5 million or 4% of global turnover. The
relationship between the United Kingdom and the European Union with respect to certain aspects of data protection law remains
unclear, for example around how data can lawfully be transferred between each jurisdiction, which exposes us to further
compliance risk.

Although we work to comply with applicable laws, regulations and standards, our contractual obligations and other legal
obligations, these requirements are evolving and may be modified, interpreted and applied in an inconsistent manner from one
jurisdiction to another, and may conflict with one another or other legal obligations with which we must comply. Any failure or
perceived failure by us or our employees, representatives, contractors, consultants or other third parties to comply with such
requirements or adequately address privacy and security concerns, even if unfounded, could result in additional cost and liability
to us, damage our reputation, and have a material adverse effect on our business, financial condition and results of operations.

The international aspects of our business expose us to business, regulatory, political, operational, financial and
economic risks associated with doing business outside of the U.S.

We currently have limited international operations of our own and have and may have in the future a number of

international collaborations. Doing business internationally involves a number of risks, including but not limited to:

● multiple, conflicting and changing laws and regulations such as privacy regulations, tax laws, export and import

restrictions, employment laws, regulatory requirements and other governmental approvals, permits and licenses;
● failure by us or our collaboration partners to obtain and maintain regulatory approvals for the use of our products in

various countries;

● additional potentially relevant third-party patent rights;

● complexities and difficulties in obtaining protection and enforcing our intellectual property;

● difficulties in staffing and managing foreign operations by us or our collaboration partners;

● complexities associated with managing multiple payer reimbursement regimes, government payers or patient self-pay

systems by our collaboration partners;

● limits in our or our collaboration partners’ ability to penetrate international markets;

● financial risks, such as longer payment cycles, difficulty collecting accounts receivable, the impact of local and regional
financial crises on demand and payment for our products and exposure to foreign currency exchange rate fluctuations;

● natural disasters, political and economic instability, including wars, terrorism and political unrest, outbreak of disease,

boycotts, curtailment of trade and other business restrictions;

● certain expenses including, among others, expenses for travel, translation and insurance;

● expose us to sanctions, such as the sanctions levied by U.S., E.U. and Russian regulatory bodies in connection with

Russia’s military intervention in the Ukraine in March 2014; and

● regulatory and compliance risks that relate to maintaining accurate information and control over sales and 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.

If we fail to comply with environmental, health and safety laws and regulations, we could become subject to fines or
penalties or incur costs that could have a material adverse effect on the success of our business.

Our  research  and  development  activities  and  our  third-party  manufacturers’  and  suppliers’  activities  involve  the
controlled  storage,  use  and  disposal  of  hazardous  materials,  including  the  components  of  our  product  candidates  and  other
hazardous  compounds.  We  and  our  manufacturers  and  suppliers  are  subject  to  laws  and  regulations  governing  the  use,
manufacture,  storage,  handling  and  disposal  of  these  hazardous  materials.  In  some  cases,  these  hazardous  materials  and
various wastes resulting from their use are stored at our and our manufacturers’ facilities pending their use and disposal. We
cannot  eliminate  the  risk  of  contamination,  which  could  cause  an  interruption  of  our  commercialization  efforts,  research  and
development efforts and business operations, environmental damage resulting in costly cleanup and liabilities under applicable
laws  and  regulations  governing  the  use,  storage,  handling  and  disposal  of  these  materials  and  specified  waste  products.
Although we believe that the safety procedures utilized by us and our third-party manufacturers for handling and disposing of
these materials generally comply with the standards prescribed by these laws and regulations, we cannot guarantee that this is
the case or eliminate the risk of accidental contamination or injury from these materials. In such an event, we may be held liable
for any resulting damages and such liability could exceed our resources and state or federal or other applicable authorities may
curtail  our  use  of  certain  materials  and/or  interrupt  our  business  operations.  Furthermore,  environmental  laws  and  regulations
are complex, change frequently and have tended to become more stringent. We cannot predict the impact of such changes and
cannot be certain of our future compliance. We do not currently carry biological or hazardous waste insurance coverage.

Item 1B.   Unresolved Staff Comments

Not applicable.

Item 2.   Properties

Our headquarters are located in Redwood City, California, where we occupy office space under a lease that will expire in
September  2024  with  a  five-year  renewal  option.  Our  analytical  and  process  development  laboratory  is  located  in  Camarillo,
California under a lease that expires in May 2027, and contains a one-time option to extend the lease term for five years.

We believe that our existing facilities are adequate for our current needs. When our leases expire, or if we need to hire
more employees, we may exercise our renewal option or look for additional or alternate space for our operations and we believe
that suitable additional or alternative space will be available in the future on commercially reasonable terms.

Item 3.   Legal Proceedings

We are a party to the following legal proceedings:

On  March  3,  2017,  Amgen  Inc.  and  Amgen  USA  Inc.  (collectively  “Amgen”)  filed  an  action  against  us  and  other
defendants in the Superior Court of the State of California, County of Ventura. The complaint, which was amended, alleged that
we engaged in unfair competition and improperly solicited and hired certain former Amgen employees in order to acquire and
access trade secrets and other confidential information belonging to Amgen. The complaint, as amended, sought injunctive relief
and monetary damages. On May 2, 2019, we and Amgen settled the trade secret action brought by Amgen. The details of the
settlement  are  confidential  but  we  continued  to  market  UDENYCA®  and  began  to  pay  a  mid-single  digit  royalty  to  Amgen  for
five years starting on July 1, 2019.

On  May  10,  2017,  Amgen  Inc.  and  Amgen  Manufacturing  Inc.  filed  an  action  against  us  in  the  United  States  District
Court  for  the  District  of  Delaware  (the  “District  Court”)  alleging  infringement  of  one  or  more  claims  of  Amgen’s  U.S.  patent
8,273,707 (the “707 patent”) under 35 U.S.C. § 271. The complaint seeks injunctive relief, monetary damages and attorney fees.
On  December  7,  2017,  the  U.S.  Magistrate  Judge  issued  under  seal  a  Report  and  Recommendation  to  the  District  Court
recommending  that  the  District  Court  grant,  with  prejudice,  our  pending  motion  to  dismiss  Amgen  Inc.  and  Amgen
Manufacturing  Inc.’s  complaint  for  failure  to  state  a  claim  pursuant  to  Federal  Rule  of  Civil  Procedure  12(b)(6).  On  March  26,
2019, Judge Stark of the District Court adopted the U.S. Magistrate Judge’s Report and Recommendation to grant our motion
pursuant  to  Federal  Rule  of  Civil  Procedure  12(b)(6)  to  dismiss  with  prejudice  the  patent  infringement  complaint  alleging
infringement of the ‘707 patent on the grounds that such complaint failed to state a claim upon which relief may be granted. In
May 2019, Amgen filed a Notice of Appeal in the U.S. Court of Appeals for the Federal Circuit. The parties filed briefs in this
matter and oral argument was held on May 8, 2019. On July 29, 2019, the Federal Circuit issued a precedential opinion affirming
the  District  Court’s  judgment  in  our  favor.  The  Federal  Circuit  held  that  the  doctrine  of  prosecution  history  estoppel  barred
Amgen  from  succeeding  on  its  infringement  claim  and  affirmed  the  District  Court’s  dismissal.  In  a  Joint  Status  Report,  dated
September 20, 2019, Amgen stated that it does not intend to further appeal the Federal Circuit’s decision. On October 11, 2019,
we filed a Motion for Attorneys’ Fees with the District Court. Amgen filed its Answering Brief in Opposition on November 8, 2019.
On  November  22,  2019,  we  filed  our  Reply  Brief  with  the  District  Court.  On  November  30,  2020,  the  District  Court  issued  an
order denying the Company’s motion.

On  January  24,  2019,  we  filed  suit  against  Amgen  in  the  United  States  District  Court  of  Delaware  alleging  that  the
manufacture  of  Amgen’s  Humira  biosimilar,  Amgevita™,  infringes  our  U.S.  patents  10,155,039;  10,159,732;  and  10,159,733.
Each  of  our  asserted  patents  is  directed  to  stable  formulations  of  adalimumab.  On  March  5,  2019,  we  filed  an  amended
complaint asserting an additional patent, U.S. patent 10,207,000. On April 18, 2019, Amgen filed its answer and counterclaims.
On  June  24,  2019,  we  filed  our  answer  to  Amgen’s  counterclaims.  On  November  25,  2019,  the  parties  filed  a  Stipulation  of
Dismissal,  dismissing  all  claims  set  forth  in  our  amended  complaint  with  prejudice,  and  all  counterclaims  and  affirmative
defenses  set  forth  in  Amgen’s  answer,  affirmative  defenses,  and  counterclaims  as  moot.  On  November  26,  2019,  the  Court
granted the Stipulation of Dismissal. On December 9, 2019, Amgen filed a Motion for a Determination of Exceptional Case and
an Award of Fees. On January 7, 2020, we filed our Answering Brief in Opposition to Amgen’s motion. On January 21, 2020,
Amgen filed its Reply Brief. On June 11, 2020, the Court issued an order denying Amgen’s motion.

We are not a party to any other material legal proceedings on the date of this report.

Common Stockholders

As of January 31, 2021, there were approximately 29 stockholders of record of our common stock. The actual number of
stockholders  is  greater  than  this  number  of  record  holders,  and  includes  stockholders  who  are  beneficial  owners,  but  whose
shares  are  held  in  street  name  by  brokers  and  other  nominees.  This  number  of  holders  of  record  also  does  not  include
stockholders whose shares may be held in trust by other entities.

Dividend Policy

We  have  never  declared  or  paid  any  cash  dividends  on  our  capital  stock  and  do  not  anticipate  paying  any  cash
dividends  in  the  foreseeable  future.  Payment  of  cash  dividends,  if  any,  in  the  future  will  be  at  the  discretion  of  our  board  of
directors and will depend on then-existing conditions, including our financial condition, operating results, contractual restrictions,
capital  requirements,  business  prospects  and  other  factors  our  board  of  directors  may  deem  relevant.  We  entered  into  8.2%
senior  convertible  notes  in  February  2016  and  1.5%  convertible  notes  in  April  2020,  each  of  which  preclude  the  Company,
directly or indirectly, to declare dividends so long as any of the notes are outstanding.

Overview

We  are  a  commercial-stage  biopharmaceutical  company  with  a  mission  to  increase  patient  access  to  cost-effective
medicines  that  can  have  a  major  impact  on  their  lives  and  to  deliver  significant  savings  to  the  health  care  system.  We  have
become a leader in the biosimilar market by leveraging our team’s collective expertise in key areas such as process science,
analytical  characterization,  protein  production,  clinical-regulatory  development  and  commercialization.  We  began  selling
UDENYCA®  (pegfilgrastim-cbqv),  a  biosimilar  to  Neulasta,  a  long-acting  granulocyte-colony  stimulating  factor,  in  the  United
States in January 2019.

On February 1, 2021, we entered into an Exclusive License and Commercialization Agreement (the “Collaboration

Agreement”) with Shanghai Junshi Biosciences, Co., Ltd. (“Junshi Biosciences”), for the co-development and commercialization
of toripalimab, Junshi Biosciences’ anti-PD-1 antibody, in the United States and Canada. Under the Collaboration Agreement,
we will also be granted options to Junshi Biosciences’ TIGIT-targeted antibody and next generation engineered IL-2 cytokine for
evaluation as potential combination therapies with toripalimab, as well as certain negotiation rights to two early-stage checkpoint
inhibitor antibodies (the “Collaboration”). The Collaboration expands our late-stage pipeline into the rapidly growing checkpoint 
inhibitor market, which is expected to exceed $25.0 billion in the United States by 2025, and provides us a PD-1 backbone for 
potential long-term growth with next-generation immuno-oncology combinations.  Closing of the Collaboration Agreement is 
subject to clearance under the HSR Act. 

Our pre-commercial pipeline includes the following product candidates:

Oncology Pipeline

● Toripalimab, an anti-PD-1 antibody being developed in collaboration with Junshi Biosciences.

● A bevacizumab (Avastin) biosimilar candidate in collaboration with Innovent.

Immunology Pipeline

● CHS-1420 (our adalimumab (Humira) biosimilar candidate).

Opthalmology Pipeline

● A ranibizumab (Lucentis) biosimilar candidate in collaboration with Bioeq;

On  January  3,  2019,  we  initiated  the  U.S.  sales  of  UDENYCA®,  our  first  commercial  product.  While  we  have  been
profitable for the years ended December 31, 2020 and 2019, we anticipate that we may experience lower profitability and annual
losses  in  the  near  term  as  a  result  of  incurring  expenses  associated  with  upfront  and  milestone  payments  under  our
collaboration with Junshi Biosciences, if cleared under the HSR Act. Our net income was $132.2 million and $89.8 million for
the  year  ended  December  31,  2020  and  2019,  respectively,  and  our  net  loss  was  $209.4  million  for  the  year  ended
December 31, 2018. As of December 31, 2020, we had an accumulated deficit of $762.8 million.

In  February  2016,  we  issued  and  sold  $100.0  million  aggregate  principal  amount  of  our  8.2%  Convertible  Senior
Notes due in March 2022 (the “2022 Convertible Notes”). These 2022 Convertible Notes require quarterly interest distributions at
a  fixed  coupon  rate  of  8.2%  until  maturity,  redemption  or  conversion,  which  will  be  no  later  than  March  31,  2022.  If  we  fail  to
satisfy certain registration or reporting requirements, then additional interest will accrue on the 2022 Convertible Notes at a rate
of up to 0.50% per annum in the aggregate. The holders of the 2022 Convertible Notes are Healthcare Royalty Partners III, L.P.
and three of its related entities, which hold $75.0 million in aggregate principal amount, and three related party investors, KKR
Biosimilar  L.P.,  which  holds  $20.0  million,  MX  II  Associates  LLC,  which  holds  $4.0  million,  and  KMG  Capital  Partners,  LLC,
which holds $1.0 million. The 2022 Convertible Notes are convertible into shares of common stock at an initial conversion rate of
44.7387 shares of common stock per $1,000 principal amount of the 2022 Convertible Notes (equivalent to a conversion price of
approximately $22.35 per share of common stock, representing a 60% premium over the average last reported sale price of our
common stock over the 15 trading days preceding the date the 2022 Convertible Notes were issued), subject to adjustment in
certain events. Upon conversion of the 2022 Convertible Notes by a holder, the holder will receive shares of our common stock,
together, if applicable, with cash in lieu of any fractional share. After March 31, 2020, the full amount of the 2022 Convertible
Notes not previously converted are redeemable for cash at our option if the last reported sale price per share of our common
stock exceeds 160% of the conversion price on 20 or more trading days during the 30 consecutive trading days preceding the

67

Table of Contents

date on which we send notice of such redemption to the holders of the 2022 Convertible Notes. At maturity or redemption, if not
earlier converted, we will pay 109% of the principal amount of the 2022 Convertible Notes, together with accrued and unpaid
interest, in cash. In April 2020, we amended the 2022 Convertible Notes purchase agreement in connection with the issuance
and sale of our 2026 Convertible Notes (as defined below).

In October 2016, we entered into a sales agreement with Cowen and Company, LLC (“Cowen”), under which we offered
and sold our common stock, having aggregate gross proceeds of up to $100.0 million, from time to time through Cowen as our
sales agent (the “ATM Offering Program”). In the first quarter of 2019, we sold 761,130 shares of common stock at a weighted
average price of $11.17 per share under the ATM Offering Program for aggregate net proceeds of $8.2 million. Following such
sales, the ATM Offering Program terminated as all shares authorized thereunder had been sold.

On January 7, 2019 (the “Term Loan Closing Date”), we entered into a credit agreement (the “Term Loan”) with affiliates
of Healthcare Royalty Partners (together, the “Lender”). The Term Loan consists of a six-year term loan facility for an aggregate
principal amount of $75.0 million (the “Borrowings”). Our obligations under the loan documents are guaranteed by our material
domestic U.S. subsidiaries.

The  Borrowings  under  the  Term  Loan  bear  interest  through  maturity  at  7.00%  per  annum  plus  LIBOR  (customarily
defined).  Pursuant  to  the  terms  of  the  Term  Loan,  the  interest  rate  was  reduced  to  6.75%  per  annum  plus  LIBOR  as  of
January 1, 2020 as the consolidated net sales (customarily defined) for UDENYCA® for the fiscal year ending December 31,
2019, were in excess of $250.0 million. Interest is payable quarterly in arrears.

We  are  required  to  pay  principal  on  the  Borrowings  in  equal  quarterly  installments  beginning  on  the  four  year
anniversary of the Term Loan Closing Date (or, if consolidated net sales of UDENYCA® in the fiscal year ending December 31,
2021 are less than $375.0 million, beginning on the three year anniversary of the Term Loan Closing Date), with the outstanding
balance to be repaid on January 7, 2025, the maturity date.

We  are  also  required  to  make  mandatory  prepayments  of  the  Borrowings  under  the  Term  Loan,  subject  to  specified
exceptions,  with  the  proceeds  of  asset  sales,  extraordinary  receipts,  debt  issuances  and  specified  other  events  including  the
occurrence of a change in control.

If all or any of the Borrowings are prepaid or required to be prepaid under the Term Loan, then we shall pay, in addition
to such prepayment, a prepayment premium equal to (i) with respect to any prepayment paid or required to be paid on or prior to
the three year anniversary of the Term Loan Closing Date, 5.00% of the Borrowings prepaid or required to be prepaid, plus all
required interest payments that would have been due on the Borrowings prepaid or required to be prepaid through and including
the three year anniversary of the Term Loan Closing Date, (ii) with respect to any prepayment paid or required to be paid after
the three year anniversary of the Term Loan Closing Date but on or prior to the four year anniversary of the Term Loan Closing
Date, 5.00% of the Borrowings prepaid or required to be prepaid, (iii) with respect to any prepayment paid or required to be paid
after  the  four  year  anniversary  of  the  Term  Loan  Closing  Date  but  on  or  prior  to  the  five  year  anniversary  of  the  Term  Loan
Closing  Date,  2.50%  of  the  Borrowings  prepaid  or  required  to  be  prepaid,  and  (iv)  with  respect  to  any  prepayment  paid  or
required to be prepaid thereafter, 1.25% of the Borrowings prepaid or required to be prepaid.

In connection with the Term Loan, we paid a fee to the Lender of approximately $1.1 million at closing in the form of an
original issue discount. Upon the prepayment or maturity of the Borrowings (or upon the date such prepayment or repayment is
required to be paid), we are required to pay an additional exit fee in an amount equal to 4.00% of the total principal amount of
the Borrowings.

The obligations under the Term Loan are secured by a lien on substantially all of our and our Guarantors’ tangible and
intangible  property,  including  intellectual  property.  The  Term  Loan  contains  certain  affirmative  covenants,  negative  covenants
and events of default, including, covenants and restrictions that among other things, restrict our ability and our subsidiaries to,
incur liens, incur additional indebtedness, make loans and investments, engage in mergers and acquisitions, in asset sales, and
declare dividends or redeem or repurchase capital stock. Additionally, the consolidated net sales for UDENYCA® must not be
lower than $70.0 million for the fiscal year ending December 31, 2019, (b) $125.0 million for the fiscal year ending December 31,
2020,  and  (c)  $150.0  million  for  each  fiscal  year  thereafter.  A  failure  to  comply  with  these  covenants  could  permit  the  Lender
under the Term Loan to declare the Borrowings, together with accrued interest and fees, to be immediately due and payable. In
April  2020,  we  amended  the  Term  Loan  in  connection  with  the  issuance  and  sale  of  our  2026  Convertible  Notes  (as  defined
below).

68

Table of Contents

In  April  2020,  we  issued  and  sold  $230.0  million  aggregate  principal  amount  of  1.5%  convertible  senior  subordinated
notes  due  in  2026  (the  “2026  Convertible  Notes”)  in  a  private  offering  to  qualified  institutional  buyers  pursuant  to  Rule  144A
under  the  Securities  Act.  In  connection  with  the  pricing  of  the  2026  Convertible  Notes,  we  entered  into  privately  negotiated
capped call transactions with one or more of the initial purchasers or their respective affiliates and/or other financial institutions
(the “Option Counterparties”). The cap price of the capped call transactions will initially be $25.9263 per share, which represents
a  premium  of  approximately  75.0%  over  the  last  reported  sale  price  of  our  common  stock  of  $14.815  per  share  on  April  14,
2020,  and  is  subject  to  certain  adjustments  under  the  terms  of  the  capped  call  transactions.  The  2026  Convertible  Notes  are
general  unsecured  obligations  and  will  be  subordinated  to  our  designated  senior  indebtedness.  The  2026  Convertible  Notes
accrue  interest  at  a  rate  of  1.5%  per  annum,  payable  semi-annually  in  arrears  on  April  15  and  October  15  of  each  year,
beginning on October 15, 2020, and will mature on April 15, 2026, unless earlier repurchased or converted. At any time before
the close of business on the second scheduled trading day immediately before the maturity date, holders may convert their 2026
Convertible  Notes  at  their  option  into  shares  of  our  common  stock,  together,  if  applicable,  with  cash  in  lieu  of  any  fractional
share, at the then-applicable conversion rate. The initial conversion rate is 51.9224 shares of common stock per $1,000 principal
amount of 2026 Convertible Notes, which represents an initial conversion price of approximately $19.26 per share of common
stock. The initial conversion price represents a premium of approximately 30.0% over the last reported sale of $14.815 per share
of our common stock on the Nasdaq Global Market on April 14, 2020. The conversion rate and conversion price will be subject
to  customary  adjustments  upon  the  occurrence  of  certain  events.  If  a  “make-whole  fundamental  change”  (as  defined  in  the
indenture for the 2026 Convertible Notes) occurs, we will, in certain circumstances, increase the conversion rate for a specified
period of time for holders who convert their 2026 Convertible Notes in connection with that make-whole fundamental change.
The  2026  Convertible  Notes  are  not  redeemable  at  our  election  before  maturity.  If  a  “fundamental  change”  (as  defined  in  the
indenture for the 2026 Convertible Notes) occurs, then, subject to a limited exception, holders may require us to repurchase their
2026 Convertible Notes for cash. The repurchase price will be equal to the principal amount of the 2026 Convertible Notes to be
repurchased, plus accrued and unpaid interest, if any, to, but excluding, the applicable repurchase date. The net proceeds from
the  offering  were  $222.2  million,  net  of  the  initial  purchasers’  fees  and  the  offering  expenses.  We  used  approximately  $18.2
million of the net proceeds to fund the cost of entering into the capped call transactions.

COVID-19 Update

As  a  result  of  the  COVID-19  outbreak,  we  have  experienced  and  may  continue  to  experience  disruptions  that  could
severely impact our business, clinical trials and preclinical studies. See “Risk Factors ”. These and other factors arising from the
COVID-19  pandemic  could  result  in  us  not  being  able  to  maintain  UDENYCA®’s  market  position  or  increase  its  penetration
against all Neulasta’s dosage forms, and could result in our inability to meet development milestones for our product candidates,
each  of  which  would  harm  our  business,  financial  condition,  results  of  operations  and  growth.  We  expect  the  COVID-19
pandemic to have some adverse impact on our sales growth on a year-over-year basis.

While the long-term economic impact and the duration of the COVID-19 pandemic may be difficult to assess or predict,
the widespread pandemic has resulted in, and may continue to result in, significant disruption of global financial markets, which
could reduce our ability to access capital and could negatively affect our liquidity and the liquidity and stability of markets for our
common  stock  and  our  convertible  notes.  In  addition,  a  recession,  further  market  correction  or  depression  resulting  from  the
spread of COVID-19 could materially affect our business and the value of our notes and our common stock.

Financial Operations Overview

Revenue

Our  first  FDA  approved  product,  UDENYCA®,  was  approved  in  November  2018,  and  we  initiated  U.S.  sales  of
UDENYCA®  on  January  3,  2019.  We  recorded  net  product  revenue  of  $475.8  million  and  $356.1  million  for  the  years  ended
December 31, 2020 and 2019, respectively.

Cost of Goods Sold

Cost  of  goods  sold  consists  primarily  of  third-party  manufacturing,  distribution,  and  overhead  costs  associated  with
UDENYCA®. A portion of the costs of producing UDENYCA® sold to date was expensed as research and development prior to
the FDA approval of UDENYCA® and therefore it is not reflected in the cost of goods sold.

69

Table of Contents

On May 2, 2019, we settled a trade secret action brought by Amgen Inc. and Amgen USA Inc. (collectively “Amgen”). As
a  result,  the  cost  of  goods  sold  reflects  a  mid-single  digit  royalty  on  net  product  revenue,  which  began  on  July  1,  2019.  The
royalty cost will continue for five years per the terms of the settlement agreement.

Research and Development Expense

Research  and  development  expense  represents  costs  incurred  to  conduct  research,  such  as  the  discovery  and
development of our product candidates. We recognize all research and development costs as they are incurred. We currently
track  research  and  development  costs  incurred  on  a  product  candidate  basis  only  for  external  research  and  development
expenses. Our external research and development expense consists primarily of:

● expense  incurred  under  agreements  with  consultants,  third-party  contract  research  organizations  (“CROs”),  and
investigative sites where a substantial portion of our preclinical studies and all of our clinical trials are conducted;

● costs of acquiring originator comparator materials and manufacturing preclinical study and clinical trial supplies and
other materials from contract manufacturing organizations (“CMOs”), and related costs associated with release and
stability testing;

● costs associated with manufacturing process development activities; and

● certain upfront and milestone payments related to licensing and collaboration agreements.

Internal  costs  are  associated  with  activities  performed  by  our  research  and  development  organization  and  generally
benefit  multiple  programs.  These  costs  are  not  separately  allocated  by  product  candidate.  Unallocated,  internal  research  and
development costs consist primarily of:

● personnel-related expense, which include salaries, benefits and stock-based compensation; and

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

The largest component of our total operating expense has historically been our investment in research and development

activities, including the clinical development and manufacturing process development of our product candidates. We received
regulatory approval for UDENYCA® and as a result, all of our manufacturing costs for this product are capitalized as inventory
and subsequently expensed as costs of goods sold when the inventory is sold. We expect our research and development
expense in 2021 to be substantially higher than in 2020 due to the incurrence of the $150.0 million upfront payment as well as
additional potential milestone payments to Junshi Biosciences and other additional increased development costs. 

We  consider  regulatory  approval  of  product  candidates  to  be  uncertain,  and  any  products  manufactured  prior  to
regulatory  approval  may  not  be  sold  unless  regulatory  approval  is  obtained.  We  expense  manufacturing  costs  as  incurred  for
product candidates prior to regulatory approval as research and development expense. If, and when, regulatory approval of a
product candidate is obtained, we will begin capitalizing manufacturing costs related to the approved product into inventory.

Selling, General and Administrative Expense

Selling,  general  and  administrative  expense  consists  primarily  of  personnel  costs,  allocated  facilities  costs  and  other
expense  for  outside  professional  services,  including  legal,  insurance,  human  resources,  outside  marketing,  advertising,  audit
and  accounting  services,  as  well  as  costs  associated  with  establishing  commercial  capabilities  in  support  of  the
commercialization  of  UDENYCA®.  Personnel  costs  consist  of  salaries,  benefits  and  stock-based  compensation.  Our  selling,
general and administrative expense in 2020 was lower than expected as certain sales and marketing activities were decreased
due to the COVID-19 pandemic. We expect our selling, general and administrative expense in 2021 to be higher than in 2020 as
a  result  of  anticipated  increased  commercial  activities  to  support  UDENYCA®  sales  and  as  a  result  of  initiating  our
ophthalmology and immuno-oncology commercial activities.

Interest Expense

Interest expense consists primarily of interest incurred on our outstanding indebtedness and non-cash interest related to
the  amortization  of  debt  discount  and  debt  issuance  costs  associated  with  our  various  debt  agreements  outstanding  during
the years ended December 31, 2020, 2019 and 2018.

Other Income, Net

Other income, net for the years ended December 31, 2020, 2019 and 2018, consists of gains and losses resulting from
the remeasurement of our contingent consideration, interest earned from our investments in marketable securities and foreign
exchange  gains  and  losses  resulting  from  currency  fluctuations.  We  will  continue  to  record  adjustments  to  the  estimated  fair
value of our contingent consideration related to the Compound Transaction Payment until the contingency settles or expires.

Significant Transactions

1.5% Convertible Senior Subordinated Notes due 2026

In  April  2020,  we  issued  and  sold  $230.0  million  aggregate  principal  amount  of  1.5%  convertible  senior  subordinated
notes due 2026 (the “2026 Convertible Notes”) in a private offering to qualified institutional buyers pursuant to Rule 144A under
the Securities Act. The 2026 Convertible Notes are general unsecured obligations and will be subordinated to our designated
senior indebtedness. The 2026 Convertible Notes accrue interest at a rate of 1.5% per annum, payable semi-annually in arrears
on  April  15  and  October  15  of  each  year,  beginning  on  October  15,  2020,  and  will  mature  on  April  15,  2026,  unless  earlier
repurchased or converted.

At  any  time  before  the  close  of  business  on  the  second  scheduled  trading  day  immediately  before  the  maturity  date,
noteholders may convert their 2026 Convertible Notes at their option into shares of our common stock, together, if applicable,
with cash in lieu of any

fractional  share,  at  the  then-applicable  conversion  rate.  The  initial  conversion  rate  is  51.9224  shares  of  common  stock  per
$1,000 principal amount of the 2026 Convertible Notes, which represents an initial conversion price of approximately $19.26 per
share of common stock. The initial conversion price represents a premium of approximately 30.0% over the last reported sale of
$14.815 per share of our common stock on the Nasdaq Global Market on April 14, 2020. The conversion rate and conversion
price will be subject to customary adjustments upon the occurrence of certain events. If a “make-whole fundamental change” (as
defined in the indenture for the 2026 Convertible Notes) occurs, we will, in certain circumstances, increase the conversion rate
for  a  specified  period  of  time  for  noteholders  who  convert  their  2026  Convertible  Notes  in  connection  with  that  make-whole
fundamental change. The 2026 Convertible Notes are not redeemable at our election before maturity. If a “fundamental change”
(as defined in the indenture for the 2026 Convertible Notes) occurs, then, subject to a limited exception, noteholders may require
us to repurchase their 2026 Convertible Notes for cash. The repurchase price will be equal to the principal amount of the 2026
Convertible Notes to be repurchased, plus accrued and unpaid interest, if any, to, but excluding, the applicable repurchase date.

In  connection  with  the  pricing  of  the  2026  Convertible  Notes,  we  entered  into  privately  negotiated  capped  call
transactions  with  one  or  more  of  the  Option  Counterparties.  The  cap  price  of  the  capped  call  transactions  will  initially  be
$25.9263 per share, which represents a premium of approximately 75.0% over the last reported sale price of our common stock
of $14.815 per share on April 14, 2020, and is subject to certain adjustments under the terms of the capped call transactions.

The net proceeds from the offering were $222.2 million, net of the initial purchasers’ discounts and commissions and the
offering  expenses.  We  used  approximately  $18.2  million  of  the  net  proceeds  to  fund  the  cost  of  entering  into  the  capped  call
transactions.

The  2026  Convertible  Notes  are  accounted  for  in  accordance  with  ASC  470-20,  Debt  with  Conversion  and  Other
Options (“ASC 470-20”) and ASC 815-40, Contracts in Entity’s Own Equity  (“ASC  815-40”).  Under  ASC  815-40,  to  qualify  for
equity  classification  (or  nonbifurcation,  if  embedded)  the  instrument  (or  embedded  feature)  must  be  both  (1)  indexed  to  the
issuer’s  stock  and  (2)  meet  the  requirements  of  the  equity  classification  guidance.  We  determined  that  the  2026  Convertible
Notes do contain embedded features indexed to our own stock, but do not meet the requirements for bifurcation, and therefore
do not need to be separately accounted for as an equity component. Since the embedded conversion feature meets the equity
scope  exception  from  derivative  accounting,  and  also  since  the  embedded  conversion  option  does  not  need  to  be  separately
accounted for as an equity component under ASC 470-20, the proceeds received from the issuance of the convertible debt were
recorded  as  a  liability  on  the  consolidated  balance  sheet.  We  evaluated  the  capped  call  transactions  under  ASC  815-10  and
determined  that  it  should  be  accounted  as  a  separate  transaction  from  the  2026  Convertible  Notes  and  that  the  capped  calls
should be classified as equity instruments. Therefore, the capped call premium paid in the amount of $18.2 million was recorded
as a reduction to additional paid-in capital. The capped calls will not be subsequently re-measured as long as the conditions for
equity classification continue to be met.

Critical Accounting Policies and Estimates

Our  management’s  discussion  and  analysis  of  our  financial  condition  and  results  of  operations  is  based  on  our
consolidated financial statements, which have been prepared in accordance with United States generally accepted accounting
principles  (“U.S.  GAAP”).  The  preparation  of  these  consolidated  financial  statements  requires  us  to  make  estimates  and
assumptions that affect the reported amounts of assets and liabilities and the disclosure of contingent assets and liabilities at the
date  of  the  consolidated  financial  statements,  as  well  as  the  reported  revenue  generated  and  expense  incurred  during  the
reporting  periods.  As  appropriate,  we  periodically  evaluate  our  critical  accounting  policies  and  estimates.  Our  estimates  are
based  on  our  historical  experience  and  on  various  other  factors  that  we  believe  to  be  reasonable  under  the  circumstances.
These  estimates  form  the  basis  for  making  judgments  about  the  carrying  value  of  assets  and  liabilities  that  are  not  readily
apparent from other sources. Accounting estimates and judgements are inherently uncertain and the actual results could differ
from these estimates.

Net Product Revenue

We account for sales of UDENYCA® under Topic 606 Revenue from Contracts with Customers. We sell UDENYCA® to
wholesalers and distributors, (collectively, “Customers”). Our Customers resell UDENYCA® to hospitals and clinics (collectively,
“Healthcare  Providers”)  under  set  contracts  with  us.  In  addition  to  distribution  agreements  with  Customers  and  contracts  with
Healthcare Providers, we enter into arrangements with group purchasing organizations (“GPOs”) that provide for government-
mandated  or  privately-negotiated  rebates,  chargebacks  and  discounts  with  respect  to  the  purchase  of  UDENYCA®.  We  also
enter  into  rebate  arrangements  with  payers,  which  consist  primarily  of  commercial  insurance  companies,  to  cover  the
reimbursement of UDENYCA® to Healthcare Providers. We provide co-payment

72

Table of Contents

assistance to patients who have commercial insurance and meet certain eligibility requirements. Revenue from product sales is
recognized  when  a  Customer  controls  the  product,  which  occurs  upon  delivery  of  UDENYCA®  to  and  acceptance  by  that
Customer.

Product Sales Discounts and Allowances

Revenue from product sales is recorded at the net sales price (“transaction price”), which includes estimates of variable
consideration  for  which  reserves  are  established  and  that  result  from  discounts,  chargebacks,  rebates,  co-pay  assistance,
returns and other allowances that are offered within contracts between us and our Customers, Healthcare Providers, payers and
GPOs relating to the sales of UDENYCA®. These reserves are based on the amounts earned or to be claimed on the related
sales and are classified as reductions in trade receivables (if the amounts are payable to the customer) or current liabilities (if
the amounts are payable to a party other than a customer). Where appropriate, these estimates take into consideration a range
of  possible  outcomes  that  are  probability-weighted  for  relevant  factors  such  as  historical  experience,  current  contractual  and
statutory  requirements,  specifically  known  market  events  and  trends,  industry  data  and  forecasted  customer  buying  and
payment  patterns.  Overall,  these  reserves  reflect  the  best  estimates  of  the  amount  of  consideration  to  which  we  are  entitled
based  on  the  term  of  our  contracts.  The  amount  of  variable  consideration  that  is  included  in  the  transaction  price  may  be
constrained, and is included in the net sales price only to the extent that it is probable that a significant reversal in the amount of
the cumulative revenue recognized will not occur in a future period. The actual amount of consideration ultimately received may
differ from our estimates. If actual results in the future vary from our estimates, the estimates will be adjusted, which will affect
net product revenue in the period that such variances become known.

Chargebacks: Chargebacks  are  discounts  that  occur  when  Healthcare  Providers  purchase  directly  from  a  Customer.
Healthcare  Providers,  which  belong  to  Public  Health  Service  institutions,  non-profit  clinics,  government  entities,  GPOs,  and
health maintenance organizations, generally purchase the product at a discounted price. The Customer, in turn, charges back to
us the difference between the price initially paid by the Customer and the discounted price paid by the Healthcare Providers to
the Customer. The allowance for chargebacks is based on an estimate of sales to contracted Customers.

Discounts  for  Prompt  Payment:  We  provide  prompt  payment  discounts  to  our  Customers,  which  are  recorded  as  a

reduction in revenue in the same period that the related product revenue is recognized.

Rebates:  Allowances  for  rebates  include  mandated  discounts  under  the  Medicaid  Drug  Rebate  Program,  other
government  programs  and  commercial  contracts.  Rebate  amounts  owed  after  the  final  dispensing  of  the  product  to  a  benefit
plan  participant  are  based  upon  contractual  agreements  or  legal  requirements  with  public  sector  benefit  providers,  such  as
Medicaid. Certain rebate amounts commensurate with share utilization of UDENYCA® related to other pegfilgrastim products.
The  allowance  for  rebates  is  based  on  statutory  or  contractual  discount  rates  and  expected  utilization.  Our  estimates  for  the
expected  utilization  of  rebates  are  based  on  customer  and  payer  data  received  from  the  pharmacies  and  distributors  and
historical  utilization  rates.  Rebates  are  generally  invoiced  by  the  payer  and  paid  in  arrears,  such  that  the  accrual  balance
consists  of  an  estimate  of  the  amount  expected  to  be  incurred  for  the  current  quarter’s  shipments  to  our  Customers,  plus  an
accrual balance for known prior quarters’ unpaid rebates. If actual future rebates vary from estimates, we may need to adjust our
accruals, which would affect net product revenue in the period of adjustment.

Co-payment Assistance: Patients who have commercial insurance and meet certain eligibility requirements may receive
co-payment assistance. The calculation of the accrual for co-pay assistance is based on an estimate of claims and the cost per
claim that we expect to receive associated with product that has been recognized as revenue.

Product Returns:  We  offer  our  Customers  a  limited  product  return  right,  which  is  principally  based  upon  whether  the
product  is  damaged  or  defective,  or  the  product’s  expiration  date.  Product  return  allowance  is  estimated  and  recorded  at  the
time of sale.

Other  Allowances:  We  pay  fees  to  Customers  for  account  management,  data  management  and  other  administrative
services.  To  the  extent  that  the  services  received  are  distinct  from  the  sale  of  products  to  the  customer,  these  payments  are
classified  in  selling,  general  and  administrative  expense  in  our  consolidated  statements  of  operations,  otherwise  they  are
included as a reduction in product revenue.

Inventory

Prior to the regulatory approval of our product candidates, we incurred expenses for the manufacture of drug product
that  could  potentially  be  available  to  support  the  commercial  launch  of  our  products.  We  began  to  capitalize  inventory  costs
associated with

73

Table of Contents

UDENYCA® after receiving regulatory approval for UDENYCA® in November 2018 when it was determined that the inventory
had a probable future economic benefit.

Our inventory is stated at the lower of cost or estimated net realizable value with cost determined under the first-in first-
out  method.  Inventory  costs  include  third-party  contract  manufacturing,  third-party  packaging  services,  freight,  labor  costs  for
personnel involved in the manufacturing process, and indirect overhead costs. We primarily use actual costs to determine the
cost  basis  for  inventory.  The  determination  of  whether  inventory  costs  will  be  realizable  requires  our  review  of  the  expiration
dates  of  our  product  UDENYCA®  compared  to  our  forecasted  sales.  If  actual  market  conditions  are  less  favorable  than
projected  by  us,  write-downs  of  inventory  may  be  required  which  would  be  recorded  as  cost  of  sales  in  our  consolidated
statement of operations.

Income Taxes

We file U.S. federal and state income tax with varying statutes of limitations. The tax years from 2011 forward remain
open to examination due to the carryover of unused net operating losses and tax credits. To date, we have not been audited by
the Internal Revenue Service or any state income tax authority.

We  use  the  liability  method  of  accounting  for  income  taxes.  Under  this  method,  deferred  tax  assets  and  liabilities  are
determined  based  on  the  differences  between  the  financial  reporting  and  the  tax  bases  of  assets  and  liabilities  and  are
measured using the enacted tax rates and laws that will be in effect when the differences are expected to reverse. We assess
the likelihood that the resulting deferred tax assets will be realized. A valuation allowance is provided when it is more likely than
not that some portion or all of a deferred tax asset will not be realized.

As of December 31, 2020, our total net deferred tax assets, net of gross deferred tax liabilities, were $200.9 million. Due
to the weight of the negative evidence, which is primarily our history of losses, outweighing other positive evidence, the federal
net  deferred  tax  assets  and  state  net  deferred  tax  assets  have  been  fully  offset  by  a  valuation  allowance.  The  deferred  tax
assets  were  primarily  comprised  of  net  operating  losses,  tax  credit  carryforwards,  stock-based  compensation  expenses  and
sales related accruals. Utilization of the net operating loss and tax credit carryforwards may be subject to an annual limitation
due to historical or future ownership changes under Section 382 and 383 of the Internal Revenue Code of 1986, as amended,
and similar state provisions.

Net product revenue for the year ended December 31, 2020 was $475.8 million compared to $356.1 million for the year
ended December 31, 2019, an increase of $119.8 million. The increase was primarily due to an increase in the number of units
of  UDENYCA®  sold,  which  was  partially  offset  by  an  increase  in  discounts  and  allowances  incurred  during  the  year  ended
December 31, 2020.

During  the  second  quarter  of  2020,  we  identified  that  certain  of  our  commercial  payer  invoices  were  erroneously
overstated and we received a refund of $7.5 million from these payers related to fiscal year 2019 which resulted in an increase
in net product revenue by the same amount for 2020.

We expect our net product revenue to decline during 2021, as a result of COVID-19 impact and new market entrants.

Net product revenue for the year ended December 31, 2019 was $356.1 million due to the U.S. sales of UDENYCA®,

which commenced in January 2019. There were no product sales during the year ended December 31, 2018.

The cost of goods sold was $37.7 million for the year ended December 31, 2020 compared to $17.1 million for the year
ended  December  31,  2019.  Cost  of  goods  sold  consists  primarily  of  third-party  manufacturing,  distribution,  overhead  costs
associated with the sale of UDENYCA® and a mid-single digit royalty cost on net product revenue to Amgen, which began on
July  1,  2019  and  will  continue  for  five  years.  A  portion  of  the  manufacturing  costs  for  inventory  were  incurred  prior  to  the
regulatory  approval  of  UDENYCA®  and,  therefore,  were  expensed  as  research  and  development  costs  when  incurred.  The
costs associated with this inventory were approximately $3.3 million and $24.9 million at December 31, 2020 and December 31,
2019, respectively, with estimated associated sales value of approximately $44.8 million and $367.5 million, respectively, based
on our current average net selling price for the three months ended December 31, 2020. The cost basis of product sold that was
expensed prior to approval, was approximately $21.1 million and $17.0 million for the year ended December 31, 2020 and 2019,
respectively. Had such inventories been valued at acquisition cost, it would have resulted in a corresponding increase in cost of
goods sold and a corresponding decrease in gross margin during such period. We expect to utilize the inventory expensed prior
to approval of UDENYCA® by the first quarter of 2021. Subsequent to using our entire zero cost inventory, we estimate cost of
goods  sold  as  a  percentage  of  net  product  revenue  will  be  in  the  range  of  a  high  single  digit  to  low  double  digit  percentage,
including the mid-single digit royalty cost on net product revenue.

Cost of goods sold for the year ended December 31, 2019 included a write-down of manufacturing costs of $1.3 million
due  to  the  cancellation  of  certain  manufacturing  reservations  and  $0.4  million  due  to  the  write-off  of  excess  and  obsolete
inventory.

We expect our gross margin to decrease during 2021 as a result of decreasing net revenue per unit sold.

Research  and  development  expense  for  the  year  ended  December  31,  2020  was  $142.8  million  compared  to  $94.2
million  for  the  same  period  in  2019,  an  increase  of  $48.6  million.  The  increase  in  research  and  development  expense  was
primarily due to:

●

●

●

an increase of $16.0 million in costs for CHS-1420 related to the preparation of our BLA submission and activities
related to inspection readiness;

an  increase  of  $14.2  million  in  costs  for  CHS-2020  as  we  initiated  the  manufacturing  scale-up  to  produce  drug
substance and drug product for clinical trial supply;

an increase of $7.7 million in personnel, consulting and other related costs as a result of hiring personnel in research
and development to advance our programs;

an  increase  of  $6.0  million  related  to  right  of  first  negotiation  fees  cost  in  connection  with  potential  future  strategic
licensing transactions;

●

an increase of $5.0 million related to the on-body device development for UDENYCA®;

an  increase  of  $3.5  million  in  costs  incurred  to  support  opening  an  IND  application  with  the  FDA  and  continued
development of bevacizumab (Avastin) biosimilar product candidate licensed from Innovent in 2020; and

an increase of $3.0 million in facilities, supplies and materials and other infrastructure to support our research and
development programs.

The increase in research and development expense for the year ended December 31, 2020 was partially offset by:

● a  decrease  of  $3.6  million  in  upfront  and  milestone-based  license  fee  primarily  attributable  to  $11.1  million  of
upfront and milestone payments to Bioeq in 2019 partially offset by $7.5 million of upfront and milestone payments
to Innovent in 2020;

● a decrease of $3.3 million in CHS-131 related costs incurred in 2019 in connection with opening an IND application

with the FDA and the initiation of a clinical program.

We expect our research and development expense in 2021 to be substantially higher than in 2020 due to the incurrence
of $150.0 million upfront payment as well as additional potential milestone payments to Junshi Biosciences and other additional
increased development costs.

Research  and  development  expense  for  the  year  ended  December  31,  2019  was  $94.2  million  compared  to  $110.2
million  for  the  same  period  in  2018,  a  decrease  of  $16.1  million.  The  decrease  in  research  and  development  expense  was
primarily due to:

● a decrease of $33.9 million in UDENYCA® manufacturing costs as we began capitalizing these costs as inventory
after  receiving  FDA  approval  for  UDENYCA®  in  November  2018,  which  was  partially  offset  by  an  increase  in
development expense associated with an on-body device for UDENYCA®;

● a  decrease  of  $4.5  million  in  facilities,  supplies  and  materials  and  other  infrastructure  primarily  due  to  the
impairment loss of $3.9 million in the third quarter of 2018 for a machine and equipment used within research and
development;

● a decrease of $3.9 million for CHS-0214 development costs due to close-out activities for our Phase 3 open-label

extension study, which was completed in the first quarter 2018; and

● a decrease of $2.4 million in stock-based compensation expense primarily due to company-wide options granted in
April 2015 with a higher exercise price that have been fully expensed and the capitalization of certain stock-based
compensation  expense  as  inventory  after  receiving  FDA  approval  for  UDENYCA®  in  November  2018.  The
decrease was partially offset by additional stock options and awards granted in 2019.

The decrease in research and development expense for the year ended December 31, 2019 was partially offset by the

following:

● an  increase  of  $15.6  million  in  costs  primarily  attributable  to  $11.1  million  of  upfront  and  milestone  payments  to
Bioeq  and  increases  related  to  the  development  of  our  other  biosimilar  product  candidates  as  we  continued  to
advance our pipeline;

● an  increase  of  $6.4  million  in  personnel,  consulting  and  other  related  costs  as  a  result  of  hiring  personnel  in

research and development to advance our programs;

● an  increase  of  $3.6  million  in  costs  related  to  CHS-131  in  connection  with  opening  an  initial  new  drug  (“IND”)

application with the FDA and conducting a clinical trial; and

● an increase of $3.0 million in costs for CHS-1420 related to the preparation of our BLA.

Selling,  general  and  administrative  expense  for  the  year  ended  December  31,  2020  was  $139.1  million  compared  to

$137.0 million for the same period in 2019, an increase of $2.0 million. The increase was primarily due to the following:

●

●

a  net  increase  of  $12.8  million  for  personnel,  consulting,  professional  services,  marketing,  advertising  and  other
related  expenses  due  to  an  increase  in  sales  force  personnel  and  related  commercial  functions  to  support  the
continued growth in UDENYCA® sales, which was partially offset by a decrease of $3.8 million in travel expenses as
a result of shelter-in-place response to COVID-19; and

an increase of $2.1 million in facilities, supplies and materials and other infrastructure  related  expenses  to  support
our growing commercial infrastructure for UDENYCA®.

These  increases  were  partially  offset  by  a  decrease  of  $9.0  million  in  legal  costs  related  to  entering  into  a  legal

settlement with Amgen in May 2019.

We expect our selling, general and administrative expense in 2021 to be higher than in 2020 as a result of anticipated
increased  commercial  activities  to  support  UDENYCA®  sales  and  as  a  result  of  initiating  our  ophthalmology  and  immuno-
oncology commercial activities.

Selling,  general  and  administrative  expense  for  the  year  ended  December  31,  2019  was  $137.0  million  compared  to
$94.2  million  for  the  same  period  in  2018,  an  increase  of  $42.9  million.  The  increase  in  selling,  general  and  administrative
expense was primarily due to:

● an increase of $35.6 million for personnel, consulting and other related expenses due to an increase in sales force
personnel and related commercial functions in connection with the ongoing commercialization of UDENYCA®;

● an  increase  of  $3.6  million  for  marketing,  advertising,  recruiting  and  other  professional  services  to  support  the
ongoing  commercialization  of  UDENYCA®,  which  was  partially  offset  by  a  decrease  in  legal  costs  as  a  result  of
entering into a legal settlement with Amgen in May 2019;

● an  increase  of  $2.5  million  in  facility  and  other  general  and  administrative  expenses  to  support  our  growing

commercial infrastructure for UDENYCA®; and

● an  increase  of  $1.1  million  in  stock-based  compensation  expense  due  to  an  increase  in  commercial-related
headcount  and  additional  stock  options  and  awards  granted  in  2019.  The  increase  was  partially  offset  by  a
decrease resulting from the company-wide options granted in April 2015 with a higher exercise price that have been
fully expensed.

Interest expense for the year ended December 31, 2019 was $17.6 million compared to $9.7 million for the same period
in 2018, an increase of $7.9 million. The increase in interest expense was primarily attributable to the Term Loan we entered into
in January 2019.

Other income, net for the year ended December 31, 2020 was $0.6 million compared to $2.6 million for the year ended
December 31, 2019, a decrease of $2.1 million. The decrease in other income, net was primarily due to decrease of $1.3 million
in interest income due to lower portfolio yields as a result of decrease in interest rates in 2020 and a decrease of $0.6 million
due to fluctuations in foreign exchange rates.

Other income, net was higher in 2018 compared to that of 2019 because the fair value of our contingent liability related
to  the  Compound  Transaction  Payment  associated  with  our  InteKrin  acquisition  decreased  as  a  result  of  a  decrease  in  the
probability of occurrence from 33% to 10% and an extension in the timing of occurrence to a later date.

Income  tax  provision  for  the  year  ended  December  31,  2020  was  $3.5  million  compared  to  $2.9  million  for  the  same
period  in  2019,  an  increase  of  $0.5  million.  Income  tax  provision  primarily  relates  to  state  taxes  in  jurisdictions  outside  of
California,  for  which  we  have  a  limited  operating  history.  Our  historical  losses  are  sufficient  to  fully  offset  any  federal  taxable
income. The income tax provision differed from the U.S. federal statutory rate of 21% primarily due to the effect of change in the
valuation  allowance  against  our  federal  deferred  tax  assets,  which  reduced  our  net  tax  expense.  We  maintain  a  full  valuation
allowance against our net deferred tax assets due to our history of losses.

There was no income tax provision for the year ended December 31, 2018 as we maintained a full valuation allowance

against our net deferred tax assets due to our history of losses during these periods.

Liquidity and Capital Resources

Due  to  our  significant  research  and  development  expenditures,  and  although  we  are  profitable  for  the  years  ended
December  31,  2020  and  2019,  we  previously  generated  significant  operating  losses  since  our  inception.  We  funded  our
operations primarily through the equity financing, sales of our convertible preferred stock, sales of UDENYCA® units, issuance
of debt and payments received under our collaboration and license agreements.

In October 2016, we entered into a sales agreement with Cowen, under which we offered and sold our common stock,
having  aggregate  gross  proceeds  of  up  to  $100.0  million,  from  time  to  time  through  Cowen  as  our  sales  agent  in  our  ATM
Offering  Program.  In  January  2019,  we  issued  and  sold  an  aggregate  of  761,130  shares  of  common  stock  at  a  weighted
average price of $11.17 per share under the ATM Offering Program for aggregate net proceeds of $8.2 million. As of January 19,
2019, our Shelf Registration Statement expired and accordingly the ATM Offering Program was terminated.

On January 7, 2019 (the “Term Loan Closing Date”), we entered into a credit agreement (the “Term Loan”) with affiliates
of Healthcare Royalty Partners (together, the “Lender”). The Term Loan consists of a six-year term loan facility for an aggregate
principal amount of $75.0 million (the “Borrowings”). Our obligations under the loan documents are guaranteed by our material
domestic  U.S.  subsidiaries.  The  Borrowings  under  the  Term  Loan  bear  interest  through  maturity  at  7.00%  per  annum  plus
LIBOR (customarily defined).

Table of Contents

The  consolidated  net  sales  (customarily  defined)  for  UDENYCA®  for  the  fiscal  year  ending  December  31,  2019,  exceeded
$250.0 million, which resulted in an interest rate reduction to 6.75% per annum plus LIBOR, effective January 1, 2020. Interest is
payable quarterly in arrears. We are required to pay principal on the Borrowings in equal quarterly installments beginning on the
four  year  anniversary  of  the  Term  Loan  Closing  Date  (or,  if  consolidated  net  sales  of  UDENYCA®  in  the  fiscal  year  ending
December 31, 2021 are less than $375.0 million, beginning on the three year anniversary of the Term Loan Closing Date), with
the  outstanding  balance  to  be  repaid  on  January  7,  2025,  the  maturity  date.  We  are  also  required  to  make  mandatory
prepayments  of  the  Borrowings  under  the  Term  Loan,  subject  to  specified  exceptions,  with  the  proceeds  of  asset  sales,
extraordinary receipts, debt issuances and specified other events including the occurrence of a change in control. If all or any of
the Borrowings are prepaid or required to be prepaid under the Term Loan, then we shall pay, in addition to such prepayment, a
prepayment  premium  equal  to  (i)  with  respect  to  any  prepayment  paid  or  required  to  be  paid  on  or  prior  to  the  three  year
anniversary of the Term Loan Closing Date, 5.00% of the Borrowings prepaid or required to be prepaid, plus all required interest
payments that would have been due on the Borrowings prepaid or required to be prepaid through and including the three year
anniversary of the Term Loan Closing Date, (ii) with respect to any prepayment paid or required to be paid after the three year
anniversary of the Term Loan Closing Date but on or prior to the four year anniversary of the Term Loan Closing Date, 5.00% of
the  Borrowings  prepaid  or  required  to  be  prepaid,  (iii)  with  respect  to  any  prepayment  paid  or  required  to  be  paid  after  the
four year anniversary of the Term Loan Closing Date but on or prior to the five year anniversary of the Term Loan Closing Date,
2.50%  of  the  Borrowings  prepaid  or  required  to  be  prepaid,  and  (iv)  with  respect  to  any  prepayment  paid  or  required  to  be
prepaid thereafter, 1.25% of the Borrowings prepaid or required to be prepaid. In connection with the Term Loan, we paid a fee
to the Lender of approximately $1.1 million at closing in the form of an original issue discount. Upon the prepayment or maturity
of the Borrowings (or upon the date such prepayment or repayment is required to be paid), we are required to pay an additional
exit fee in an amount equal to 4.00% of the total principal amount of the Borrowings. The obligations under the Term Loan are
secured by a lien on substantially all of our and our Guarantors’ tangible and intangible property, including intellectual property.
The  Term  Loan  contains  certain  affirmative  covenants,  negative  covenants  and  events  of  default,  including,  covenants  and
restrictions that among other things, restrict our ability and our subsidiaries to, incur liens, incur additional indebtedness, make
loans  and  investments,  engage  in  mergers  and  acquisitions,  in  asset  sales,  and  declare  dividends  or  redeem  or  repurchase
capital  stock.  Additionally,  the  consolidated  net  sales  for  UDENYCA®  must  not  be  lower  than  $70.0  million  for  the  fiscal  year
ending  December  31,  2019,  (b)  $125.0  million  for  the  fiscal  year  ending  December  31,  2020,  and  (c)  $150.0  million  for  each
fiscal  year  thereafter.  A  failure  to  comply  with  these  covenants  could  permit  the  Lender  under  the  Term  Loan  to  declare  the
Borrowings, together with accrued interest and fees, to be immediately due and payable.

In  April  2020,  we  issued  and  sold  $230  million  aggregate  principal  amount  of  1.5%  convertible  senior  subordinated
notes due 2026 (the “2026 Convertible Notes”) in a private offering to qualified institutional buyers pursuant to Rule 144A under
the Securities Act. In connection with the pricing of the 2026 Convertible Notes, we entered into privately negotiated capped call
transactions  with  one  or  more  of  the  Option  Counterparties.  The  cap  price  of  the  capped  call  transactions  will  initially  be
$25.9263 per share, which represents a premium of approximately 75.0% over the last reported sale price of our common stock
of $14.815 per share on April 14, 2020, and is subject to certain adjustments under the terms of the capped call transactions.
The 2026 Convertible Notes are general unsecured obligations and will be subordinated to our designated senior indebtedness.
The  2026  Convertible  Notes  accrue  interest  at  a  rate  of  1.5%  per  annum,  payable  semi-annually  in  arrears  on  April  15  and
October  15  of  each  year,  beginning  on  October  15,  2020,  and  will  mature  on  April  15,  2026,  unless  earlier  repurchased  or
converted. At any time before the close of business on the second scheduled trading day immediately before the maturity date,
holders may convert their 2026 Convertible Notes at their option into shares of our common stock, together, if applicable, with
cash  in  lieu  of  any  fractional  share,  at  the  then-applicable  conversion  rate.  The  initial  conversion  rate  is  51.9224  shares  of
common  stock  per  $1,000  principal  amount  of  2026  Convertible  Notes,  which  represents  an  initial  conversion  price  of
approximately  $19.26  per  share  of  common  stock.  The  initial  conversion  price  represents  a  premium  of  approximately  30.0%
over  the  last  reported  sale  of  $14.815  per  share  of  our  common  stock  on  the  Nasdaq  Global  Market  on  April  14,  2020.  The
conversion  rate  and  conversion  price  will  be  subject  to  customary  adjustments  upon  the  occurrence  of  certain  events.  If  a
“make-whole  fundamental  change”  (as  defined  in  the  indenture  for  the  2026  Convertible  Notes)  occurs,  we  will,  in  certain
circumstances, increase the conversion rate for a specified period of time for holders who convert their 2026 Convertible Notes
in connection with that make-whole fundamental change. The 2026 Convertible Notes are not redeemable at our election before
maturity. If a “fundamental change” (as defined in the indenture for the 2026 Convertible Notes) occurs, then, subject to a limited
exception, holders may require us to repurchase their 2026 Convertible Notes for cash. The repurchase price will be equal to the
principal amount of the 2026 Convertible Notes to be repurchased, plus accrued and unpaid interest, if any, to, but excluding,
the applicable repurchase date. The net proceeds from the offering were $222.2 million, net of the initial purchasers’ fees and
the offering expenses. We used approximately $18.2 million of the net proceeds to fund the cost of entering into the capped call
transactions.

In 2020, we purchased investments in marketable securities in accordance with our investment policy in order to obtain

interest income on our cash balances.

Table of Contents

As of December 31, 2020, we had an accumulated deficit of $762.8 million and cash and cash equivalents of $541.2
million. We had $132.2 million in net income for the year ended December 31, 2020. We believe that our current available cash,
cash equivalents and cash collected from UDENYCA® sales will be sufficient to fund our planned expenditures and meet our
obligations  for  at  least  the  next  12  months  following  our  financial  statement  issuance  date.  We  may  need  to  raise  additional
funds in the future; however, there can be no assurance that such efforts will be successful or that, in the event that they are
successful, the terms and conditions of such financing will be favorable to us.

●

●

a decrease in accounts payable of $9.8 million primarily due to the timing of receiving and processing invoices from
our vendors.

a decrease in lease liabilities of $1.4 million due to the lease payments for 2020.

Cash provided by operating activities was $28.4 million for the year ended December 31, 2019, which was primarily due

to the following:

● net income of $89.8 million;

● an increase in accrued rebates, fees and reserve of $51.1 million as a result of UDENYCA® sales;

million, non-cash operating lease expense of $1.8 million and excess and obsolete inventory of $0.4 million;

● upfront  and  milestone  payments  related  to  license  and  collaboration  arrangements  of  $11.1  million  are  being
reclassified as investing activities to provide better alignment between the cash flows and the underlying nature of
those transactions;

● an  increase  in  accrued  and  other  liabilities  of  $10.4  million  primarily  due  to  our  accruals  for  our  UDENYCA®

manufacturing and royalty expenses;

● an increase in accrued compensation of $10.0 million primarily due to increased compensation and bonus accrual

attributable to increase in headcount and as a result of attainment of certain corporate goals during 2019; and

● an increase in accounts payable of $9.9 million due to the timing of receiving and processing invoices.

The cash provided by operating activities was partially offset by the following:

● an increase in trade receivables of $142.0 million due to initiating sales of UDENYCA® on January 3, 2019;

● an increase in inventory of $48.2 million as we began capitalizing inventory in November 2018 upon receiving FDA

approval for UDENYCA®;

the following:

● a net loss of $209.4 million;

approval for UDENYCA®; and

● a  decrease  in  accounts  payable,  accounts  payable-related  parties,  accrued  liabilities  and  other  liabilities  of  $0.9
million  primarily  due  to  the  payments  to  our  CROs  and  CMOs  as  a  result  of  the  progression  of  our  clinical  trial
programs that are winding down, and the timing of certain vendor payments.

The cash used in operating activities was partially offset by the following:

● non-cash charges related to stock-based compensation of $34.8 million;

● impairment  of  fixed  asset  equipment  of  $3.9  million,  depreciation  and  amortization  of  property  and  equipment  of

bonuses were paid in RSUs in December 2017; and

● a decrease in prepaid manufacturing, other prepaid and other assets of $8.2 million as we utilized the prepayment

for our pre-commercial manufacturing of UDENYCA®.

Net cash used in investing activities

Cash used in investing activities of $14.4 million for the year ended December 31, 2020 was primarily due to purchases
of investments in marketable securities of $273.8 million, upfront and milestone-based license fee payments of $7.5 million to
Innovent and purchases of property and equipment of $7.2 million partially offset by the proceeds from maturities of investments
in marketable securities of $274.0 million.

and  collaboration  arrangement  of  $11.1  million  and  purchases  of  property  and  equipment  of  $1.8  million.  The  cash  used  in
investing activities was partially offset by proceeds from maturities of investments in marketable securities of $20.4 million.

term  investments  in  marketable  securities  of  $42.9  million,  the  purchase  of  the  non-controlling  interest  of  $0.7  million  and
purchases of property and equipment of $0.8 million. The cash used in investing activities was partially offset by proceeds from
maturities of investments in marketable securities of $43.2 million.

Net cash provided by financing activities

Cash  provided  by  financing  activities  of  $223.9  million  for  the  year  ended  December  31,  2020  was  primarily  due  to
$222.2 million in proceeds from the issuance of 2026 Convertible Notes, net of issuance costs, $17.4 million proceeds from the
exercise of stock options and $3.8 million proceeds from purchases under the Employee Stock Purchase Plan (“ESPP”) partially
offset by $18.2 million of capped call option purchases related to 2026 Convertible Notes, $0.9 million in tax payments related to
net share settlement of bonus payout in RSUs and $0.4 million in principal payments for finance lease obligations.

Cash provided by financing activities of $89.4 million for year ended December 31, 2019 was primarily related to $73.0
million in proceeds from our term loan, net of issuance costs, $8.1 million from the issuance of our common stock from our ATM
Offering Program, net of underwriting discounts, commissions and offering costs, $5.6 million from the exercise of stock options
and $3.5 million in proceeds related to our ESPP. The proceeds were partially offset by payments of $0.8 million for taxes related
to the net shares settlement of bonus payout in RSUs.

Cash  provided  by  financing  activities  of  $105.4  million  for  year  ended  December  31,  2018  was  primarily  due  to  net
proceeds  of  $102.3  million  from  the  issuance  of  our  common  stock  from  an  underwritten  public  offering  in  May  2018  and  our
ATM Offering Program,

82

Table of Contents

net  of  underwriting  discounts  and  commissions,  $2.0  million  from  the  exercise  of  stock  options,  and  $1.6  million  in  proceeds
related to our ESPP. The proceeds were partially offset by payments of $0.5 million for offering expenses related to the issuance
of common stock.

Funding Requirements

We  believe  that  our  current  available  cash,  cash  equivalents,  and  cash  collected  from  UDENYCA®  sales  will  be
sufficient to fund our planned expenditures and meet our obligations for the foreseeable future, beyond the 12 months following
our financial statement issuance date. We have based this estimate on assumptions that may prove to be wrong, and we could
utilize  our  available  capital  resources  sooner  than  we  currently  expect.  Further,  our  operating  plan  may  change,  and  we  may
need  additional  funds  to  meet  operational  needs  and  capital  requirements  for  product  development  and  commercialization
sooner than planned. Because of the numerous risks and uncertainties associated with the development and commercialization
of  our  product  candidates  and  the  extent  to  which  we  may  enter  into  additional  agreements  with  third  parties  to  participate  in
their  development  and  commercialization,  we  are  unable  to  estimate  the  amounts  of  increased  capital  outlays  and  operating
expenditures associated with our current and anticipated research and development activities, and on-going and future licensing
and collaboration obligations. Our future funding requirements will depend on many factors, including the following:

● cash proceeds from UDENYCA® sales;

● the costs of manufacturing, distributing and marketing UDENYCA®;

● the cost of manufacturing clinical supplies and any products that we may develop;

● the terms and timing of any other collaborative, licensing and other arrangements that we have established or may

establish;

● the  timing,  receipt  and  amount  of  sales,  profit  sharing  or  royalties,  if  any,  from  any  product  candidates  that  are

● the number and characteristics of product candidates that we pursue;

and other materials from CMOs and related costs associated with release and stability testing;

If  the  proceeds  from  UDENYCA®  sales  are  insufficient  or  are  not  collected  in  a  timely  manner  and  or  our  operating
expenses are higher than the proceeds from UDENYCA® sales, we may need to raise additional capital to fund our operations
in  the  near  future.  Funding  may  not  be  available  to  us  on  acceptable  terms,  or  at  all.  If  we  are  unable  to  obtain  adequate
financing when needed, we may have to delay, reduce the scope of or suspend one or more of our clinical trials or research and
development programs. We may seek to raise any necessary additional capital through a combination of public or private equity
offerings,  debt  financings,  collaborations,  strategic  alliances,  licensing  arrangements  and  other  marketing  and  distribution
arrangements. We may seek to enter into strategic partnerships to commercialize our biosimilar candidates in ex-US territories
or  globally  for  certain  therapeutic  areas.  To  the  extent  that  we  raise  additional  capital  through  marketing  and  distribution
arrangements or other collaborations, strategic alliances or licensing arrangements with third parties, we may have to relinquish
valuable rights to our product candidates, future revenue streams, research programs or product candidates or to grant licenses
on  terms  that  may  not  be  favorable  to  us.  If  we  do  raise  additional  capital  through  public  or  private  equity  offerings,  the
ownership interest of our existing stockholders will be diluted, and the terms of these securities may include liquidation or other
preferences  that  adversely  affect  our  stockholders’  rights.  If  we  raise  additional  capital  through  debt  financing,  we  may  be
subject

to additional covenants limiting or restricting our ability to take specific actions, such as incurring additional debt, making capital
expenditures or declaring dividends.

Off-Balance Sheet Arrangements

Since  our  inception,  we  have  not  engaged  in  any  off-balance  sheet  arrangements,  as  defined  in  the  rules  and

(2) These amounts are comprised of non-cancelable purchase commitments to our CMOs.
(3) These amounts are comprised of future minimum rent payment on our facility leases.
(4) These amounts are comprised of future minimum rent payment on our vehicle leases.

The Company enters into contracts in the normal course of business with CROs for preclinical studies and clinical trials
and CMOs for the manufacture of drug materials. The contracts are cancellable, with varying provisions regarding termination. If
a contract with a specific vendor were to be terminated, the Company would only be obligated for products or services that the
Company had received as of the effective date of the termination and any applicable cancellation fees.

Item 7A.   Quantitative and Qualitative Disclosures about Market Risk

As of December 31, 2020, we had cash and cash equivalents of $541.2 million. A portion of our cash equivalents, which
are in money market funds, may be subject to interest rate risk and could fall in value if market interest rates increase. However,
because  our  cash  equivalents  are  primarily  short-term  in  duration,  we  believe  that  our  exposure  to  interest  rate  risk  is  not
significant and a 1% movement in market interest rates would not have a significant impact on the total value of our portfolio.

We  are  exposed  to  market  risk  related  to  changes  in  foreign  exchange  rates.  We  contract  with  CROs  and  contract
manufacturers  globally  and  thus  we  face  foreign  exchange  risk  as  a  result  of  entering  into  transactions  denominated  in
currencies other than U.S. dollars. Due to the uncertain timing of expected payments in foreign currencies, we do not utilize any
forward exchange contracts. All foreign transactions settle on the applicable spot exchange basis at the time such payments are
made. An adverse movement in foreign exchange rates could have a material effect on payments made to foreign suppliers and
for  license  agreements.  A  hypothetical  10%  change  in  foreign  exchange  rates  during  any  of  the  periods  presented  would  not
have had a material impact on our financial statements. We do not enter into investments for trading or speculative purposes
and have not used any derivative financial instruments to manage our interest rate risk exposure.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Stockholders and the Board of Directors of Coherus BioSciences, Inc.

Opinion on the Financial Statements

We have audited the accompanying consolidated balance sheets of Coherus BioSciences, Inc., (the Company) as of December
31, 2020 and 2019, the related consolidated statements of operations, comprehensive income (loss), stockholders’ equity
(deficit), 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 25, 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 Matter

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

Description of the
Matter

    Estimate of Reserves for Chargebacks and Rebates

As described in Note 2 to the consolidated financial statements, the Company recognizes revenues
from product sales at the net sales price, which includes estimates of reserves for chargebacks and
rebates it provides to hospitals, clinics, and payers under commercial and government programs.
These reserves are recorded in the period when sales occur and are based on the amounts to be
claimed on the related sales which may not be known at the point of sale. Chargebacks and rebates
are estimated based on expected channel and payer mix, and contracted discount rates, adjusted for
current period assumptions. Estimated chargebacks are recorded as a reduction of trade receivables
on the consolidated balance sheet and totaled $40.0 million at December 31, 2020. Estimated rebates
are presented within accrued rebates, fees and reserves on the consolidated balance sheet and
totaled $54.1 million at December 31, 2020.

Auditing the estimates for chargebacks and rebates was complex due to the judgmental nature of the
assumptions used. In particular for product that remains in the distribution channel at December 31,
2020, management is required to estimate the portion of product that is expected to be subject to a
chargeback and rebate as well as the applicable discount rate.

How We Addressed
the Matter in Our Audit

We obtained an understanding, evaluated the design and tested the operating effectiveness of internal
controls over the Company's estimates of chargebacks and rebates, which are accounted for as
reductions to revenue. This included controls over management’s review of significant assumptions
used in the estimates such as expected channel and payer mix and contractual discount rate.

To test the Company's estimated reserves for chargebacks and rebates, our audit procedures
included, among others, testing the accuracy and completeness of the underlying data used in the
Company’s analyses and evaluating the significant assumptions stated above. Specifically, for
estimated chargebacks and rebates, we obtained third-party channel inventory reports and reviewed
the remaining inventory in the distribution channel, tested historical channel and payer mix data, and
compared applicable contractual chargeback or rebate percentages applied against executed
chargeback and rebate agreements. We also assessed the completeness and accuracy of current and
historical channel and payer mix and discount rate data used in management’s estimates and
performed sensitivity analyses to determine the effect of changes in assumptions, where appropriate.

We have served as the Company’s auditor since 2012.

Organization and Operations

Description of the Business

Coherus BioSciences, Inc.

Basis of Presentation and Summary of Significant Accounting Policies

Basis of Consolidation

The accompanying consolidated financial statements have been prepared in accordance with U.S. generally accepted
accounting principles (“U.S. GAAP”). The accompanying consolidated financial statements include the accounts of Coherus and
its wholly owned subsidiaries as of December 31, 2020: Coherus Intermediate Corp, InteKrin Therapeutics Inc. (“InteKrin”) and
InteKrin’s  wholly-owned  subsidiary,  InteKrin  Russia.  Unless  otherwise  specified,  references  to  the  Company  are  references  to
Coherus  and  its  consolidated  subsidiaries.  All  intercompany  transactions  and  balances  have  been  eliminated  upon
consolidation.

Liquidity

As of December 31, 2020, the Company had an accumulated deficit of $762.8 million and cash and cash equivalents of
$541.2 million. The Company had $132.2 million in net income for the year ended December 31, 2020. The Company believes
that its current available cash, cash equivalents and cash collected from UDENYCA® sales will be sufficient to fund its planned
expenditures  and  meet  the  Company’s  obligations  for  at  least  12  months  following  its  financial  statement  issuance  date. The
Company  may  need  to  raise  additional  funds  in  the  future;  however  there  can  be  no  assurance  that  such  efforts  will  be
successful  or  that,  in  the  event  that  they  are  successful,  the  terms  and  conditions  of  such  financing  will  be  favorable.  If  the
Company is unable to obtain adequate financing when needed, it may have to delay, reduce the scope of or suspend one or
more of its clinical trials, or research and development programs.

Use of Estimates

The  preparation  of  financial  statements  in  conformity  with  U.S.  GAAP  requires  management  to  make  judgements,
estimates and assumptions that affect the reported amounts of assets, liabilities, revenue and expenses, and related disclosures
reported in the financial statements. Management uses significant judgment when making estimates including, but not limited to:
those related to revenue recognition, including determining the nature and timing of satisfaction of performance obligations, and
determining the standalone selling price of performance obligations, and variable consideration such as rebates, chargebacks,
sales returns and sale allowances, as well as milestones included in collaboration and license arrangements; related to its stock-
based compensation, valuation of deferred tax assets, impairment of goodwill and long-lived assets, the valuation of acquired
intangible  assets,  valuation  and  reserves  for  inventory,  clinical  trial  accruals,  contingent  consideration,  convertible  notes
valuation, as well as certain accrued liabilities. Management bases its estimates on historical experience and on other various
assumptions that are believed to be reasonable under the circumstances. These estimates form the basis for making judgments
about the carrying values of assets and liabilities when these values are not readily apparent from other sources. Accounting
estimates and judgements are inherently uncertain and the actual results could differ from these estimates.

Table of Contents

During  the  second  quarter  of  2020,  the  Company  identified  that  certain  of  its  commercial  payer  invoices  were
erroneously  overstated.  The  Company  received  a  refund  of  $7.5  million  from  these  payers  related  to  fiscal  year  2019  which
resulted  in  an  increase  in  net  product  revenue  of  $7.5  million  for  the  year  ended  December  31,  2020.  The  refund  adjustment
resulted  in  an  increase  in  basic  and  diluted  net  income  per  share  of  $0.11  and  $0.09,  respectively,  during  the  year  ended
December  31,  2020.  Accrued  commercial  payer  rebates  of  $27.9  million  and  $14.0  million  were  recorded  in  accrued  rebates,
fees and reserve as of December 31, 2020 and December 31, 2019, respectively, in the consolidated balance sheet.

Foreign Currency

The  functional  currency  of  InteKrin  Russia,  which  the  Company  acquired  in  February  2014,  is  the  Russian  Ruble.
Accordingly,  the  financial  statements  of  this  subsidiary  are  translated  into  U.S.  dollars  using  appropriate  exchange  rates.
Unrealized gains or losses on translation are recognized in accumulated other comprehensive loss in the consolidated balance
sheet.

For  the  years  ended  December  31,  2020,  2019  and  2018,  the  foreign  exchange  gains  and  losses  recorded  in  other
income, net in the consolidated statements of operations were a net loss of $333,000, net gain of $239,000 and a net loss of
$571,000, respectively.

Segment Reporting and Revenue by Geographic Region

The Company operates and manages its business as one reportable and operating segment, which is the business of
developing  and  commercializing  biosimilar  products  and,  as  part  of  the  InteKrin  acquisition,  small  molecules.  The  Company’s
chief  executive  officer,  who  is  the  chief  operating  decision  maker,  reviews  financial  information  on  an  aggregate  basis  for
purposes of allocating resources and evaluating financial performance. All revenue is generated in the United States of America
and all Long-lived assets are primarily maintained in the United States of America.

Cash, Cash Equivalents and Restricted Cash

Cash,  cash  equivalents  and  restricted  cash  are  comprised  of  cash  and  highly  liquid  investments  with  remaining
maturities  of  90  days  or  less  at  the  date  of  purchase.  The  Company  limits  cash  investments  to  financial  institutions  with  high
credit standings; therefore, management believes that there is no significant exposure to any credit risk in the Company’s cash,
cash equivalents and restricted cash.

The  following  table  provides  a  reconciliation  of  cash,  cash  equivalents  and  restricted  cash  within  the  consolidated
balance  sheets  and  which,  in  aggregate,  represent  the  amount  reported  in  the  consolidated  statements  of  cash  flows  (in
thousands):

Restricted  cash  –  non-current  consists  of  deposits  for  a  letter  of  credit  that  the  Company  has  provided  to  secure  its

obligations under certain facility and other leases.

The  Company  classifies  the  up-front  and  milestone  payments  related  to  licensing  arrangements  as  cash  flows  from

investing activities in its consolidated statements of cash flows.

Investments in Marketable Securities

Management  determines  the  appropriate  classification  of  investments  in  marketable  securities  at  the  time  of  purchase
based upon management’s intent with regards to such investment and reevaluates such designation as of each balance sheet
date. The Company’s investment policy requires that it only invests in highly-rated securities and limit its exposure to any single
issuer.  All  investments  in  marketable  securities  are  held  as  “available-for-sale”  and  are  carried  at  the  estimated  fair  value  as
determined based upon quoted market prices or pricing models for similar securities.

94

    
    
 
 
 
 
Table of Contents

The  Company  classifies  investments  in  marketable  securities  as  short-term  when  they  have  remaining  contractual
maturities  of  one  year  or  less  from  the  balance  sheet  date.  Unrealized  gains  and  losses  are  reported  as  a  component  of
accumulated comprehensive income (loss), with the exception of unrealized losses believed to be related to credit losses, which,
if any, are recognized through earnings in the period the impairment occurs. Impairment assessments are made at the individual
security  level  each  reporting  period.  When  the  fair  value  of  an  investment  is  less  than  its  cost  at  the  balance  sheet  date,  a
determination is made as to whether the impairment is related to a credit loss and, if it is, the portion of the impairment relating to
credit loss is recorded as an allowance through net income. Realized gains and losses and declines in value judged to be other
than  temporary,  if  any,  on  available-for-sale  securities  are  included  in  other  income,  net,  based  on  the  specific  identification
method. For the years ended December 31, 2020, 2019 and 2018, interest income from marketable securities was $0.6 million,
$1.6 million and $1.4 million, respectively.

Trade Receivables

Trade receivables are recorded net of allowances for chargebacks, chargeback prepayments, cash discounts for prompt
payment  and  credit  losses.  The  Company  estimates  an  allowance  for  expected  credit  losses  by  considering  factors  such  as
historical  experience,  credit  quality,  the  age  of  the  accounts  receivable  balances,  and  current  economic  conditions  that  may
affect  a  customer’s  ability  to  pay.  The  corresponding  expense  for  the  credit  loss  allowance  is  reflected  in  selling,  general  and
administrative expenses. The credit loss allowance was immaterial as of December 31, 2020.

Concentration of Credit Risk

The  Company’s  financial  instruments  that  are  exposed  to  concentration  of  credit  risk  consist  primarily  of  cash,  cash
equivalents  and  restricted  cash.  The  Company  maintains  its  cash  in  bank  accounts,  which  at  times  exceed  federally  insured
limits. The Company attempts to minimize the risks related to cash, cash equivalents and restricted cash by investing in money
markets with a broad and diverse range of financial instruments. The investment portfolio is maintained in accordance with the
Company’s  investment  policy,  which  defines  allowable  investments,  specifies  credit  quality  standards  and  limits  the  credit
exposure of any single issuer. The Company also maintains restricted cash in money market funds that invest primarily in U.S.
Treasury securities. The Company has not recognized any losses from credit risks on such accounts during any of the periods
presented. The Company believes it is not exposed to significant credit risk on its cash and money market funds.

The Company is subject to credit risk from trade receivables related to the product sales in the United States. To date,
the Company has not experienced significant losses with respect to the collection of trade receivables. The Company believes
that its allowance for doubtful accounts was adequate at December 31, 2020.

The  Company  entered  into  a  strategic  commercial  supply  agreement  with  KBI  Biopharma  (“KBI”)  for  the  supply  of
UDENYCA®. The Company currently has not engaged back-up suppliers or vendors for this single-sourced service. If KBI is not
able to manufacture the supply needed in the quantities and timeframe required, the Company may not be able to supply the
product in a timely manner.

Fair Value of Financial Instruments

Fair  value  accounting  is  applied  to  all  financial  assets  and  liabilities  and  non-financial  assets  and  liabilities  that  are

recognized or disclosed at fair value in the financial statements on a recurring basis.

Inventory

Prior to the regulatory approval of the product candidates, the Company incurred expenses for the manufacture of drug
product that could potentially be available to support the commercial launch of its products. The Company began to capitalize
inventory costs associated with UDENYCA® after receiving regulatory approval for UDENYCA® in November 2018 when it was
determined that the inventory had a probable future economic benefit.

Inventory is stated at the lower of cost or estimated net realizable value with cost determined under the first-in first-out
method.  Inventory  costs  include  third-party  contract  manufacturing,  third-party  packaging  services,  freight,  labor  costs  for
personnel  involved  in  the  manufacturing  process,  and  indirect  overhead  costs.  The  Company  primarily  uses  actual  costs  to
determine  the  cost  basis  for  inventory.  The  determination  of  whether  inventory  costs  will  be  realizable  requires  management
review of the expiration dates of UDENYCA®

95

Table of Contents

compared to its forecasted sales. If actual market conditions are less favorable than projected by management, write-downs of
inventory may be required, which would be recorded as cost of goods sold in the consolidated statement of operations.

Property and Equipment

Property and equipment is stated at cost less accumulated depreciation and amortization. Maintenance and repairs are
charged to expense as incurred, and costs of improvements are capitalized. Depreciation and amortization is recognized using
the straight-line method over the following estimated useful lives:

Computer equipment and software
Furniture and fixtures
Machinery and equipment
Leasehold improvements

3 years
5 years
5 years
  Shorter of lease term or useful life

Impairment of Long Lived Assets and Acquired Intangible Asset

The  Company  reviews  long-lived  assets,  including  property  and  equipment,  and  indefinite-lived  intangible  assets  for
impairment  whenever  events  or  changes  in  circumstances  indicate  that  the  carrying  amount  of  the  assets  may  not  be  fully
recoverable.  An  impairment  loss  would  be  recognized  when  the  estimated  undiscounted  future  cash  flows  expected  to  result
from the use of the asset and its eventual disposition is less than its carrying amount. Impairment, if any, is measured as the
amount by which the carrying value of a long-lived asset exceeds its fair value. There were no impairments recorded during the
year ended December 31, 2020. For the years ended December 31, 2019 and 2018, the Company recorded an impairment of
property  and  equipment  of  $0.1  million  and  $3.9  million,  respectively,  in  research  and  development  within  the  statement  of
operations.

The intangible assets of $2.6 million as of December 31, 2020 and 2019 comprise of acquired in-process research and
development  (“IPR&D”),  which  represents  the  fair  value  assigned  to  research  and  development  assets  that  have  not  reached
technological  feasibility.  The  Company  reviews  amounts  capitalized  as  acquired  IPR&D  for  impairment  at  least  annually,  and
whenever  events  or  changes  in  circumstances  indicate  that  the  carrying  value  of  the  assets  might  not  be  recoverable.  If  the
carrying  value  of  the  acquired  IPR&D  exceeds  its  fair  value,  then  the  intangible  asset  is  written-down  to  its  fair  value.  As  of
December  31,  2020,  there  have  been  no  such  impairments.  Once  the  product  candidate  derived  from  the  indefinite-lived
intangible asset has been developed and commercialized, the useful life will be determined, and the carrying value of the finite-
lived asset will be amortized prospectively over the estimated useful life. Alternatively, if the product candidate is abandoned, the
carrying value of the intangible will be charged to research and development expense.

Goodwill

Goodwill  represents  the  excess  of  the  purchase  price  over  the  fair  value  of  the  net  tangible  and  intangible  assets
acquired. The Company tests goodwill for impairment at least annually or more frequently if events or changes in circumstances
indicate that this asset may be impaired. The goodwill test is based on our single operating segment and reporting unit structure.

The Company compares the fair value of its reporting unit to its carrying value. If the carrying value of the net assets
assigned  to  the  reporting  unit  exceeds  the  fair  value  of  the  reporting  unit,  then  the  Company  would  need  to  determine  the
implied  fair  value  of  the  reporting  unit’s  goodwill.  If  the  carrying  value  of  the  reporting  unit’s  goodwill  exceeds  its  implied  fair
value,  then  the  Company  would  record  an  impairment  loss  equal  to  the  difference.  No  goodwill  impairment  was  identified
through December 31, 2020.

Accrued Research and Development Expense

Clinical trial costs are a component of research and development expense. The Company accrues and expenses clinical
trial  activities  performed  by  third  parties  based  upon  actual  work  completed  in  accordance  with  agreements  established  with
clinical  research  and  manufacturing  organizations  and  clinical  sites.  The  Company  determines  the  actual  costs  through
monitoring patient enrollment, discussions with internal personnel and external service providers regarding the progress or stage
of completion of trials or services and the agreed-upon fee to be paid for such services.

96

    
 
 
Table of Contents

Net Product Revenue

The  Company  accounts  for  sales  of  UDENYCA®  under  Topic  606  Revenue  from  Contracts  with  Customers.  The
Company sells UDENYCA® to wholesalers and distributors, (collectively, “Customers”). The Customers then resell UDENYCA®
to hospitals and clinics (collectively, “Healthcare Providers”) pursuant to contracts with the Company. In addition to distribution
agreements  with  Customers  and  contracts  with  Healthcare  Providers,  the  Company  enters  into  arrangements  with  group
purchasing  organizations  (“GPOs”)  that  provide  for  U.S.  government-mandated  or  privately-negotiated  rebates,  chargebacks
and  discounts  with  respect  to  the  purchase  of  UDENYCA®.  The  Company  also  enters  into  rebate  arrangements  with  payers,
which  consist  primarily  of  commercial  insurance  companies  and  government  entities,  to  cover  the  reimbursement  of
UDENYCA®  to  Healthcare  Providers.  The  Company  provides  co-payment  assistance  to  patients  who  have  commercial
insurance  and  meet  certain  eligibility  requirements.  Revenue  from  product  sales  is  recognized  when  a  Customer  controls  the
product, which occurs upon delivery of UDENYCA® to and acceptance by that Customer.

Product Sales Discounts and Allowances

Revenue from product sales is recorded at the net sales price (“transaction price”), which includes estimates of variable
consideration for which reserves are established and that result from chargebacks, rebates, co-pay assistance, prompt-payment
discounts, returns and other allowances that are offered within contracts between the Company and its Customers, Healthcare
Providers, payers and GPOs relating to the sales of UDENYCA®. These reserves are based on the amounts earned or to be
claimed on the related sales and are classified as reductions in trade receivables (if the amounts are payable to a Customer) or
current liabilities (if the amounts are payable to a party other than a Customer). Where appropriate, these estimates take into
consideration  a  range  of  possible  outcomes  that  are  probability-weighted  for  relevant  factors  such  as  historical  experience,
current  contractual  and  statutory  requirements,  specifically  known  market  events  and  trends,  industry  data  and  forecasted
Customer  buying  and  payment  patterns.  Overall,  these  reserves  reflect  the  best  estimates  of  the  amount  of  consideration  to
which the Company is entitled based on the terms of its contracts. The amount of variable consideration that is included in the
transaction price may be constrained, and is included in the net sales price only to the extent that it is probable that a significant
reversal in the amount of the cumulative revenue recognized will not occur in a future period. The actual amount of consideration
ultimately received may differ. If actual results in the future vary from the Company’s estimates, the estimates will be adjusted,
which will affect the net product revenue in the period that such variances become known.

Chargebacks: Chargebacks  are  discounts  that  occur  when  Healthcare  Providers  purchase  directly  from  a  Customer.
Healthcare  Providers,  which  belong  to  Public  Health  Service  institutions,  non-profit  clinics,  government  entities,  GPOs,  and
health maintenance organizations, generally purchase the product at a discounted price. The Customer, in turn, charges back to
the Company the difference between the price initially paid by the Customer and the discounted price paid by the Healthcare
Providers  to  the  Customer.  The  allowance  for  chargebacks  is  based  on  an  estimate  of  sales  through  to  Healthcare  Providers
from the Customer.

Discounts  for  Prompt  Payment:  The  Company  provides  for  prompt  payment  discounts  to  its  Customers,  which  are

recorded as a reduction in revenue in the same period that the related product revenue is recognized.

Rebates: Rebates include mandated discounts under the Medicaid Drug Rebate Program, other government programs
and commercial contracts. Rebate amounts owed after the final dispensing of the product to a benefit plan participant are based
upon  contractual  agreements  or  legal  requirements  with  these  public  sector  benefit  providers.  Certain  rebate  amounts
commensurate with share utilization of UDENYCA® relative to other pegfilgrastim products. The accrual for rebates is based on
statutory or contractual discount rates and expected utilization. The estimates for the expected utilization of rebates are based
on  Customer  and  commercially  available  payer  data,  as  well  as  data  collected  from  the  Healthcare  Providers,  Customers,
GPOs, and historical utilization rates. Rebates invoiced by payers, Healthcare Providers and GPOs are paid in arrears. If actual
future rebates vary from estimates, the Company may need to adjust its accruals, which would affect net product revenue in the
period of adjustment.

Co-payment Assistance: Patients who have commercial insurance and meet certain eligibility requirements may receive
co-payment assistance. The calculation of the accrual for co-pay assistance is based on an estimate of claims and the cost per
claim that the Company expects to receive associated with product that has been recognized as revenue.

Product  Returns:  The  Company  offers  its  Customers  a  limited  product  return  right,  which  is  principally  based  upon
whether  the  product  is  damaged  or  defective,  or  the  product’s  expiration  date.  Product  return  allowance  is  estimated  and
recorded at the time of sale.

97

Table of Contents

Other Allowances: The Company pays fees to Customers and GPOs for account management, data management and
other  administrative  services.  To  the  extent  that  the  services  received  are  distinct  from  the  sale  of  products  to  the  customer,
these  payments  are  classified  in  selling,  general  and  administrative  expense  in  the  Company’s  consolidated  statements  of
operations, otherwise they are included as a reduction in product revenue.

Cost of Goods Sold

Cost  of  goods  sold  consists  primarily  of  third-party  manufacturing,  distribution,  and  overhead  costs  associated  with
UDENYCA®. A portion of the costs of producing UDENYCA® sold to date was expensed as research and development prior to
the FDA approval of UDENYCA® and, therefore, it is not reflected in the cost of goods sold.

On May 2, 2019, the Company and Amgen Inc. and Amgen USA Inc. (collectively “Amgen”) settled a trade secret action
brought by Amgen. As a result, cost of goods sold reflects a mid-single digit royalty on net product revenue, which began on
July 1, 2019. The royalty cost will continue for five years pursuant to the settlement.

Cost  of  goods  sold  for  the  year  ended  December  31,  2019,  included  write-off  of  prepaid  manufacturing  costs  of  $1.3
million due to the cancellation of certain manufacturing reservations, and $0.4 million due to the write-off of excess and obsolete
inventory. There were no material inventory write-offs recorded during the years ended December 31, 2020 and 2018.

Research and Development Expense

Research and development costs are charged to expense as incurred. Research and development expense includes,
among  other  costs,  salaries  and  other  personnel-related  costs,  consultant  fees,  preclinical  costs,  cost  to  manufacture  drug
candidates,  clinical  trial  costs  and  supplies,  laboratory  supply  costs,  upfront  and  milestone  payments  under  the  licensing
agreements and facility-related costs. Costs incurred under agreements with third parties are charged to expense as incurred in
accordance with the specific contractual performance terms of such agreements. Third-party costs include costs associated with
manufacturing drug candidates, preclinical and clinical support activities. In certain cases, amounts received as reimbursement
for  research  and  development  activities  from  the  Company’s  collaborators  are  recognized  as  a  reduction  in  research  and
development expense when the Company engages in a research and development project, jointly with another party, with both
parties  incurring  costs  while  actively  participating  in  project  activities  and  sharing  costs  and  potential  benefits  of  the
arrangement. Costs incurred under arrangements where the Company provides research services approximate the amount of
revenues  recorded.  Advance  payments  for  goods  or  services  to  be  received  in  the  future  to  be  utilized  in  research  and
development activities are deferred and capitalized. The capitalized amounts are expensed as the related goods are delivered or
the services are rendered.

The Company considers regulatory approval of product candidates to be uncertain, and product manufactured prior to
regulatory  approval  may  not  be  sold  unless  regulatory  approval  is  obtained.  The  Company  expenses  manufacturing  costs  as
incurred  to  research  and  development  expense  for  product  candidates  prior  to  regulatory  approval.  If,  and  when,  regulatory
approval of a product is obtained, the Company will begin capitalizing manufacturing costs related to the approved product into
inventory.

Costs associated with the development, validation and scaling of manufacturing processes at new third party suppliers
and  regulatory  registration  of  new  third-party  manufacturing  facilities  are  recognized  as  research  and  development  expenses.
These  costs  generally  comprise  of  all  costs  incurred  in  such  activities  prior  to  the  process  performance  qualification  (“PPQ”)
production  commencement  stage  at  new  manufacturing  facilities.  Costs  incurred  after  the  PPQ  production  commencement  at
new manufacturing facilities are capitalized as inventory as the regulatory approval at that point becomes probable and the net
realizable value of the batches produced during this stage of the process is recoverable.

License Agreements

The Company has entered and may continue to enter into license agreements to access and utilize certain technology.
To determine whether the licensing transactions should be accounted for as a business combination or as an asset acquisition,
the Company makes certain judgments, which include assessing whether the acquired set of activities and assets would meet
the definition of a business under the relevant accounting rules.

98

Table of Contents

If the acquired set of activities and assets does not meet the definition of a business, the transaction is recorded as an
acquisition of assets and, therefore, any acquired IPR&D that does not have an alternative future use is charged to expense at
the  acquisition  date.  To  date  none  of  the  Company’s  license  agreements  have  been  considered  to  be  the  acquisition  of  a
business.

Selling, General and Administrative Expense

Selling,  general  and  administrative  expenses  are  primarily  comprised  of  compensation  and  benefits  associated  with
sales  and  marketing,  finance,  human  resources,  legal,  information  technology  and  other  administrative  personnel,  outside
marketing,  advertising  and  legal  expenses  and  other  general  and  administrative  costs.  The  Company  expenses  the  cost  of
advertising, including promotional expenses, as incurred. Advertising expenses were $3.8 million, $4.5 million and $2.8 million
for the years ended December 31, 2020, 2019 and 2018, respectively.

Stock-Based Compensation

The Company measures the cost of equity-based service awards based on the grant-date fair value of the award. The
compensation  cost  is  recognized  as  expense  on  a  straight-line  basis  over  the  vesting  period  for  options  and  restricted  stock
units (“RSU”). The Company accounts for forfeitures as they occur.

On  January  1,  2019,  the  Company  adopted  the  ASU  No.  2018-07,  Improvements  to  Nonemployee  Share-Based
Payment  Accounting,  which  simplifies  the  accounting  for  share-based  payments  to  nonemployees  by  aligning  it  with  the
accounting  for  share-based  payment  to  employees,  with  certain  exceptions.  Prior  to  the  adoption  of  ASU  No.  2018-07,  the
Company  accounted  for  equity  instruments  issued  to  non-employees  using  the  fair  value  approach.  These  equity  instruments
consisted  of  stock  options,  which  were  valued  using  the  Black-Scholes  option-pricing  model.  Stock-based  compensation
expense was recognized as the equity instruments were earned. The measurement of stock-based compensation was subject to
periodic adjustments as the underlying equity instruments vested.

The  Company  utilizes  the  Black-Scholes  option-pricing  model  for  estimating  fair  value  of  its  stock  options  and  ESPP
granted.  Option  valuation  models,  including  the  Black-Scholes  option-pricing  model,  require  the  input  of  highly  subjective
assumptions,  and  changes  in  the  assumptions  used  can  materially  affect  the  grant-date  fair  value  of  an  award.  These
assumptions include the risk-free rate of interest, expected dividend yield, expected volatility and the expected life of the award.
For RSUs, the Company bases the fair value of awards on the closing market value of the common stock at the date of grant.

Income Taxes

The  Company  uses  the  liability  method  of  accounting  for  income  taxes.  Under  this  method,  deferred  tax  assets  and
liabilities are determined based on the differences between the financial reporting and the tax bases of assets and liabilities and
are  measured  using  the  enacted  tax  rates  and  laws  that  will  be  in  effect  when  the  differences  are  expected  to  reverse.  The
Company  must  then  assess  the  likelihood  that  the  resulting  deferred  tax  assets  will  be  realized.  A  valuation  allowance  is
provided when it is more likely than not that some portion or all of a deferred tax asset will not be realized. Due to the Company’s
lack of earnings history, the net deferred tax assets have been fully offset by a valuation allowance.

The  Company  recognizes  uncertain  income  tax  positions  at  the  largest  amount  that  is  more  likely  than  not  to  be
sustained upon audit by the relevant taxing authority. An uncertain income tax position will not be recognized if it has less than a
50% likelihood of being sustained. The Company does not expect its unrecognized tax benefits to change significantly over the
next twelve months.

The Company’s policy is to recognize interest and/or penalties related to income tax matters in income tax expense. The
Company  had  accrued  no  amounts  for  interest  and  penalties  related  to  income  tax  matters  in  the  Company’s  consolidated
balance sheet at December 31, 2020 and 2019.

Operating and Finance Leases

The Company adopted ASU 2016-02, Leases on January 1, 2019. The Company elected the package of practical

expedients upon transition, which allows it to apply the guidance prospectively, without reassessing prior conclusions related to
contracts containing leases, lease classification and initial direct costs. Accordingly, the results for the years ended December
31, 2020 and 2019 are presented under Topic 842, and the results for the year ended December 31, 2018 are presented in
accordance with the prior lease

99

Table of Contents

guidance, ASC Topic 840: Leases. The new standard also provides practical expedients for an entity’s ongoing accounting. The
Company elected an accounting policy that does not recognize right-of-use assets and lease liabilities related to short-term
leases. The Company also elected the practical expedient to not separate lease and non-lease components for its facility and
vehicle leases. The Company did not elect to apply the hindsight expedient.

The Company determines if an arrangement is a lease at inception. Operating leases are included in operating lease

right-of-use assets, other current liabilities, and lease liabilities, non-current in the consolidated balance sheets. The Lease terms
may include options to extend or terminate the lease when it is reasonably certain that the Company will exercise any such
options. The Company recognizes operating lease expense for these leases on a straight-line basis over the term of the lease.

In 2019, the Company entered into a vehicle lease agreement, pursuant to which it currently leases 42 vehicles.
Delivery of the vehicles commenced during the first quarter of 2020. The term of each leased vehicle commences upon the
delivery of the vehicle and is for a period of 36 months. The vehicles leased under this arrangement were classified as finance
leases. Assets acquired under finance leases are included in property and equipment, net, other current liabilities, and lease
liabilities, non-current in the consolidated balance sheets and are depreciated to operating expenses on a straight-line basis
over their estimated useful lives.

With the exception of initial adoption of the new lease standard, where the Company’s incremental borrowing rate used
was the rate on the adoption date (January 1, 2019), the operating and finance lease ROU assets and the lease liabilities are
recognized based on the present value of lease payments over the lease term at the lease commencement date. The Company
uses  its  incremental  borrowing  rate  based  on  the  information  available  at  the  commencement  date  in  determining  the  lease
liabilities, as the Company's leases generally do not provide an implicit rate.

Net Income (Loss) per Share Attributable to Coherus

Basic net income (loss) per share attributable to Coherus is calculated by dividing the net income (loss) attributable to
Coherus  by  the  weighted-average  number  of  shares  of  common  stock  outstanding  for  the  period,  without  consideration  for
potential  dilutive  common  shares.  Diluted  net  income  (loss)  per  share  is  computed  by  dividing  the  net  income  (loss)  by  the
weighted average number of common shares outstanding for the period plus any diluted potential common shares outstanding
for the period determined using the treasury stock method for options, RSUs and ESPP and using the if-converted method for
the convertible notes (see Note 14).

Comprehensive Income (Loss)

Comprehensive  income  (loss)  is  composed  of  two  components:  net  income  (loss)  and  other  comprehensive  income
(loss).  Other  comprehensive  income  (loss)  refers  to  gains  and  losses  that  under  U.S.  GAAP  are  recorded  as  an  element  of
stockholders’  equity  (deficit),  but  are  excluded  from  net  income  (loss).  The  Company’s  other  comprehensive  income  (loss)
included foreign currency translation adjustments for the years ended December 31, 2020, 2019 and 2018.

Recent Accounting Pronouncements

The following are the recent accounting pronouncements adopted by the Company in 2020:

Effective  January  1,  2020,  the  Company  adopted  ASU  No.  2016-13,  Financial  Instruments  —  Credit  Losses,  (Topic
326): Measurement of Credit Losses on Financial Instruments (ASU 2016-13), which changed the impairment model for most
financial assets and certain other instruments. For trade receivables and other instruments, the Company uses a new forward-
looking expected loss model that generally results in the earlier recognition of allowances for losses. The Company is exposed
to  credit  losses  primarily  through  receivables  from  customers.  The  Company’s  expected  loss  allowance  methodology  for  the
receivables is developed using historical collection experience, current and future economic market conditions, a review of the
current aging status and financial condition of the entities. Specific allowance amounts are established to record the appropriate
allowance  for  customers  that  have  a  higher  probability  of  default.  ASU  2016-13  also  eliminates  the  concept  of  “other-than-
temporary”  impairment  when  evaluating  available-for-sale  debt  securities  and  instead  focuses  on  determining  whether  any
impairment is a result of a credit loss or other factors. An entity will recognize an allowance for credit losses on available-for-sale
debt securities, rather than an other-than-temporary impairment that reduces the cost

100

Table of Contents

basis  of  the  investment.  The  adoption  of  the  new  guidance  did  not  have  a  material  impact  on  the  Company’s  consolidated
financial statements.

In January 2017, the FASB issued ASU No. 2017-04, Intangibles-Goodwill and Other: Simplifying the Test for Goodwill
Impairment  (ASU  2017-04),  which  simplifies  the  current  requirements  for  testing  goodwill  for  impairment  by  eliminating  the
second  step  of  the  two-step  impairment  test  to  measure  the  amount  of  an  impairment  loss.  ASU  2017-04  is  effective  for  the
Company’s interim and annual reporting periods during the year ending December 31, 2020, and all annual and interim reporting
periods thereafter. The Company adopted this accounting standard as of January 1, 2020. The adoption did not have a material
impact on the Company’s consolidated financial statements.

In August 2018, the FASB issued ASU No. 2018-13, Fair Value Measurements (ASU 2018-13), which eliminates certain
disclosure  requirements  for  fair  value  measurements,  and  requires  public  entities  to  disclose  certain  new  information  and
modifies some disclosure requirements. The new guidance is effective for the Company’s interim and annual reporting periods
during the year ending December 31, 2020, and all annual and interim reporting periods thereafter. The Company adopted this
accounting  standard  as  of  January  1,  2020.  The  adoption  did  not  have  a  material  impact  on  the  Company’s  consolidated
financial statements.

The following are the recent accounting pronouncements that the Company has not yet adopted:

In  August  2020,  the  FASB  issued  ASU  No.  2020-06, Debt—Debt  with  Conversion  and  Other  Options  (Subtopic  470-
20)  and  Derivatives  and  Hedging  Contracts  in  Entity’s  Own  Equity  (Subtopic  815-40)  (“ASU  2020-06”),  which  reduces  the
number of accounting models for convertible debt instruments and convertible preferred stock as well as amends the derivatives
scope exception for contracts in an entity’s own equity. ASU 2020-06 is effective for the Company on January 1, 2022, with early
adoption permitted. The Company is currently evaluating the potential impact that this standard may have on its consolidated
financial statements and related disclosures.

The Company has reviewed other recent accounting pronouncements and concluded they are either not applicable to

the business or that no material effect is expected on the consolidated financial statements as a result of future adoption.

Fair Value Measurements

Financial  assets  and  liabilities  are  recorded  at  fair  value.  The  carrying  amounts  of  certain  of  the  Company’s  financial
instruments,  including  cash  and  cash  equivalents,  restricted  cash,  investments  in  marketable  securities,  accounts  receivable,
accounts payable and other current liabilities approximate their fair value due to their short maturities. Fair value is the price that
would  be  received  to  sell  an  asset  or  paid  to  transfer  a  liability  in  an  orderly  transaction  between  market  participants  at  the
measurement date. Valuation techniques used to measure fair value must maximize the use of observable inputs and minimize
the use of unobservable inputs. The accounting guidance describes a fair value hierarchy based on three levels of inputs that
may be used to measure fair value, of which the first two are considered observable and the last is considered unobservable.
These levels of inputs are the following:

Level 1 — Quoted prices in active markets for identical assets or liabilities.

Level 2 — Inputs other than Level 1 that are observable, either directly or indirectly, such as quoted prices for similar
assets  or  liabilities,  quoted  prices  in  markets  that  are  not  active,  or  other  inputs  that  are  observable  or  can  be
corroborated by observable market data for substantially the full term of the assets or liabilities.

Level 3 — Unobservable inputs that are supported by little or no market activity and that are significant to the fair value
of the assets or liabilities.

The Company’s financial instruments consist of Level 1 assets and Level 3 liabilities. Where quoted prices are available
in  an  active  market,  securities  are  classified  as  Level  1.  Level  1  assets  consist  of  highly  liquid  money  market  funds  that  are
included  in  cash  and  cash  equivalents,  and  restricted  cash.  There  were  no  unrealized  gains  and  losses  in  the  Company’s
investments in these money market funds.

In certain cases where there is limited activity or less transparency around inputs to valuation, securities are classified

as Level 3. Level 3 liabilities consist of the contingent consideration.

Contingent Consideration

As part of the InteKrin acquisition in February 2014, the Company recognized contingent consideration associated with
potential payments to be made to the former InteKrin stockholders upon (i) the first dosing of a human subject in the first Phase
2 Clinical Trial for CHS-131 (“Earn-Out Payment”), which was achieved and settled by the Company in March 2015, and (ii) per
a compound transaction agreement as defined in the purchase agreement (the “Compound Transaction Payment”). The size of
the Compound Transaction Payment consideration is tiered based on the size of a license or similar agreement with a third party
and the timing of such agreement.

The fair value measurement of the Compound Transaction Payment uses a probability-weighted discounted cash flow
approach based on significant inputs not observable in the market and thus represents a Level 3 measurement within the fair
value  hierarchy.  The  Compound  Transaction  analysis  as  of  December  31,  2020  applied  a  20%  risk-adjusted  discount  rate  to
measure present value and also captured an additional 8.0% credit spread for counterparty credit risk given the cash payment.
The expected cash flow is based on estimates provided by the Company’s management including the timing and probability of
occurrence. The value of the consideration is tiered based on the value of a license or similar agreement with a third party and
the timing of such agreement. Generally, increases or decreases in the probability of occurrence would result in a directionally
similar  impact  in  the  fair  value  measurement  of  the  Compound  Transaction  Payment  and  it  is  estimated  that  a  1%  increase
(decrease) in the probability of occurrence would result in an immaterial fair value fluctuation.

For the years ended December 31, 2020, 2019 and 2018, the Company recognized a loss of $0, a loss of $42,000 and
a gain of $3.2 million in other income, net in the consolidated statement of operations, respectively, as a result of the change in
the fair value of the Compound Transaction Payment.

The  decrease  of  $3.2  million  in  the  fair  value  of  the  Compound  Transaction  Payment  during  the  year  ended
December 31, 2018 was primarily a result of a decrease in the probability of occurrence from 33% to 10% and an extension in
the timing of occurrence to a later date.

1.5% Convertible Notes due 2026

The estimated fair value of the 1.5% Convertible Notes due 2026, which the Company issued in April 2020 (see
Note 8) is influenced by interest rates, the Company’s stock price and stock price volatility and is determined by prices observed
in  market  trading.  The  market  for  trading  of  the  Convertible  Notes  due  2026  is  not  considered  to  be  an  active  market  and
therefore the estimate of fair value is based on Level 2 inputs. The estimated fair value of the Convertible Notes due 2026 was
approximately $269.1 million (par value $230.0 million) as of December 31, 2020.

8.2% Convertible Notes due 2022

The estimated fair value of the 8.2% Convertible Senior Notes Due 2022, which the Company issued on February 29,
2016  (see  Note  8)  is  based  on  an  income  approach.  The  estimated  fair  value  was  approximately  $113.7  million  (par  value
$100.0 million) as of December 31, 2020 and represents a Level 3 valuation. When determining the estimated fair value of the
Company’s long-term debt, the Company uses a single factor binomial lattice model which incorporates the terms and conditions
of the convertible notes and market based risk measurement that are indirectly observable, such as credit risk. The lattice model
produces an estimated fair value based on changes in the price of the underlying common shares price over successive periods
of time. An estimated yield based on market data is used to discount straight debt cash flows.

Term Loan

The principal amount outstanding under the Company’s Term Loan (see Note 8) of $75 million as of December 31, 2020
is subject to variable interest rate, which is based on a fixed percentage plus three month LIBOR (“LIBOR”), and as such, the
Company believes the carrying amount of these obligations approximates fair value.

consisted of raw materials and a portion of work in process.

Prepaid manufacturing of $19.4 million as of December 31, 2020 includes prepayments of $8.9 million to a contract

manufacturing organization (“CMO”) for manufacturing services for UDENYCA®, which the Company expects to be converted
into inventory within the next twelve months; and prepayments of $10.5 million to various CMOs for other research and
development pipeline programs. Prepaid manufacturing of $8.6 million as of December 31, 2019 includes prepayments of $7.2
million to a CMO for manufacturing services for UDENYCA®; and prepayments of $1.4 million to various CMOs for other
research and development pipeline programs.

Other Assets, non-current of $2.1 million on the consolidated balance sheet as of December 31, 2020 primarily includes
prepayments  of  $1.3  million  made  to  a  CMO  for  manufacturing  services  for  UDENYCA®,  which  the  Company  expects  to  be
converted into inventory after twelve months. The other assets, non current balance was immaterial as of December 31, 2019.

Licensing Arrangements

Bioeq AG

On November 4, 2019, the Company entered into a license agreement with Bioeq IP AG (now Bioeq AG, or “Bioeq”) for
the  commercialization  of  a  biosimilar  version  of  ranibizumab  (Lucentis)  in  certain  dosage  forms  in  both  a  vial  and  pre-filled
syringe  presentation  (the  “Licensed  Products”).  Under  this  agreement,  Bioeq  granted  to  the  Company  an  exclusive,  royalty-
bearing  license  to  commercialize  the  Licensed  Products  in  the  field  of  ophthalmology  (and  any  other  approved  labelled
indication)  in  the  United  States.  Bioeq  will  supply  to  the  Company  the  Licensed  Products  in  accordance  with  terms  and
conditions specified in the agreement and a manufacturing and supply agreement to be executed by the parties in accordance
therewith. The agreement’s initial term continues in effect for ten years after the first commercial sale of a Licensed Product in
the  United  States,  and  thereafter  renews  for  an  unlimited  period  of  time  unless  otherwise  terminated  in  accordance  with  its
terms.

Under the agreement, Bioeq must use commercially reasonable efforts to develop and obtain regulatory approval of the
Licensed  Products  in  the  U.S.  in  accordance  with  a  development  and  manufacturing  plan,  and  the  Company  must  use
commercially  reasonable  efforts  to  commercialize  the  Licensed  Products  in  accordance  with  a  commercialization  plan.
Additionally, the Company must commit certain pre-launch and post-launch resources to the commercialization of the Licensed
Products for a limited time as specified in the agreement.

The Company accounted for the licensing transaction as an asset acquisition under the relevant accounting rules. The
Company  paid  Bioeq  an  upfront  and  a  milestone  payment  aggregating  to  €10  million  ($11.1  million),  which  was  recorded  as
research and development expense in the Company’s consolidated statement of operations for the year ended December 31,
2019. The Company is obligated to pay Bioeq an aggregate of up to €25 million in additional milestone payments in connection
with  the  achievement  of  certain  development  and  regulatory  milestones  with  respect  to  the  Licensed  Products  in  the  United
States. The Company will share a percentage of gross profits on sales of Licensed Products in the United States with Bioeq in
the  low  to  mid  fifty  percent  range.  The  additional  milestone  payments  and  royalties  are  contingent  upon  future  events  and,
therefore, will be recorded when it is probable that a milestone will be achieved or when royalties are due. As of December 31,
2020 and 2019, the Company did not have any outstanding obligations for milestones and royalties to Bioeq.

Innovent Biologics (Suzhou) Co., Ltd.

On January 13, 2020, the Company entered into a license agreement (the “License Agreement”) with Innovent Biologics
(Suzhou) Co., Ltd. (“Innovent”) for the development and commercialization of a biosimilar version of bevacizumab (Avastin) in
any dosage form and presentations (“bevacizumab Licensed Product”) in the United States and Canada (the “Territory”). Under
the License Agreement, Innovent granted to the Company an exclusive, royalty-bearing license to develop and commercialize
the bevacizumab Licensed Product in the field of treatment, prevention or amelioration of any human diseases and conditions as
included  in  the  label  of  Avastin.  Under  the  License  Agreement,  the  Company  also  acquired  an  option  to  develop  and
commercialize  Innovent’s  biosimilar  version  of  rituximab  (Rituxan®)  in  any  dosage  form  and  presentations  (the  “rituximab
Licensed  Product”  and  together  with  the  bevacizumab  Licensed  Product,  the  “Innovent  Licensed  Products”)  in  the  Territory.
Subject to the terms of the License Agreement, the Company may exercise its option within 12 months of its receipt of certain
regulatory materials from Innovent. Following the Company’s option exercise, Innovent’s biosimilar version of rituximab would be
deemed an Innovent Licensed Product for all purposes of the License Agreement and Innovent would grant to the Company an
exclusive,  royalty-bearing  license  to  develop  and  commercialize  Innovent’s  biosimilar  version  of  rituximab  in  the  field  of
treatment, prevention or amelioration of any human diseases and conditions as included in the label of Rituxan®.

Innovent  will  supply  the  Innovent  Licensed  Products  to  the  Company  in  accordance  with  a  manufacturing  and  supply
agreement to be executed by the parties. Under the License Agreement, the Company acquired the right to require Innovent to
perform  technology  transfer  for  the  manufacturing  of  the  Innovent  Licensed  Products  in  the  Territory  and,  upon  completion  of
such  technology  transfer,  the  Company  will  have  the  exclusive  right  to  manufacture  the  Innovent  Licensed  Products  in  the
Territory.

106

Table of Contents

Under the agreement, the Company committed to pay Innovent a $5.0 million upfront payment and an aggregate of up to
$40.0 million in milestone payments in connection with the achievement of certain development, regulatory and sales milestones
with respect to the bevacizumab Licensed Product and, if the Company’s option is exercised, an aggregate of up to $40.0 million
in milestone payments in connection with the achievement of certain development, regulatory and sales milestones with respect
to  the  rituximab  Licensed  Product.  The  Company  will  share  a  percentage  of  net  sales  of  Innovent  Licensed  Products  with
Innovent  in  the  mid-teens  to  low  twenty  percent  range.  If  the  Company  exercises  its  option  to  acquire  Innovent’s  biosimilar
version of rituximab (Rituxan®), it would be required to pay a fee of $5.0 million. Subject to the terms of the License Agreement,
if  the  Company  requests  Innovent  to  perform  technology  transfer  for  the  manufacturing  of  the  Innovent  Licensed  Products,  it
would be required to pay up to $10.0 million for fees related thereto. The Company accounted for the licensing transaction as an
asset  acquisition  under  the  relevant  accounting  rules.  The  Company  recorded  research  and  development  expense  of  $7.5
million during the year ended December 31, 2020 related to an upfront payment and a milestone payment for the bevacizumab
Licensed  Product.  As  of  December  31,  2020  the  Company  did  not  have  any  outstanding  milestone  or  royalty  payment
obligations to Innovent.

The additional milestone payments, option fee for licensing of rituximab (Rituxan®), manufacturing technology transfer
fee and royalties are contingent upon future events and, therefore, will be recorded when it is probable that a milestone will be
achieved, option fee or manufacturing technology transfer fee will be incurred or when royalties are due.

Debt Obligations

1.5% Convertible Senior Subordinated Notes due 2026

In  April  2020,  the  Company  issued  and  sold  $230.0  million  aggregate  principal  amount  of  its  1.5%  convertible  senior
subordinated notes due 2026 (the “2026 Convertible Notes”) in a private offering to qualified institutional buyers pursuant to Rule
144A under the Securities Act. The net proceeds from the offering were $222.2 million after deducting initial purchasers’ fees
and  offering  expenses.  The  2026  Convertible  Notes  are  general  unsecured  obligations  and  will  be  subordinated  to  the
Company’s  designated  senior  indebtedness  (as  defined  in  the  indenture  for  the  2026  Convertible  Notes)  and  structurally
subordinated to all existing and future indebtedness and other liabilities, including trade payables. The 2026 Convertible Notes
accrue  interest  at  a  rate  of  1.5%  per  annum,  payable  semi-annually  in  arrears  on  April  15  and  October  15  of  each  year,
beginning on October 15, 2020, and will mature on April 15, 2026, unless earlier repurchased or converted.

At  any  time  before  the  close  of  business  on  the  second  scheduled  trading  day  immediately  before  the  maturity  date,
noteholders may convert their 2026 Convertible Notes at their option into shares of the Company’s common stock, together, if
applicable, with cash in lieu of any fractional share, at the then-applicable conversion rate. The initial conversion rate is 51.9224
shares of common stock per $1,000 principal amount of the 2026 Convertible Notes, which represents an initial conversion price
of approximately $19.26 per share of common stock. The initial conversion price represents a premium of approximately 30.0%
over  the  last  reported  sale  of  $14.815  per  share  of  the  Company’s  common  stock  on  the  Nasdaq  Global  Market  on  April  14,
2020. The conversion rate and conversion price will be subject to customary adjustments upon the occurrence of certain events.
If a “make-whole fundamental change” (as defined in the indenture for the 2026 Convertible Notes) occurs, the Company will, in
certain  circumstances,  increase  the  conversion  rate  for  a  specified  period  of  time  for  noteholders  who  convert  their  2026
Convertible Notes in connection with that make-whole fundamental change. The 2026 Convertible Notes are not redeemable at
the Company’s election before maturity. If a “fundamental change” (as defined in the indenture for the 2026 Convertible Notes)
occurs, then, subject to a limited exception, noteholders may require the Company to repurchase their 2026 Convertible Notes
for  cash.  The  repurchase  price  will  be  equal  to  the  principal  amount  of  the  2026  Convertible  Notes  to  be  repurchased,  plus
accrued and unpaid interest, if any, to, but excluding, the applicable repurchase date.

The 2026 Convertible Notes will have customary provision relating to the occurrence of “events of default” (as defined in
the Indenture for the 2026 Convertible Notes). The occurrence of such events of default could result in the acceleration of all
amounts due under the 2026 Convertible Notes.

As of December 31, 2020, the Company was in full compliance with these covenants and there were no events of default

under the 2026 Convertible Notes.

The  2026  Convertible  Notes  are  accounted  for  in  accordance  with  ASC  470-20,  Debt  with  Conversion  and  Other
Options (“ASC 470-20”) and ASC 815-40, Contracts in Entity’s Own Equity  (“ASC  815-40”).  Under  ASC  815-40,  to  qualify  for
equity  classification  (or  nonbifurcation,  if  embedded)  the  instrument  (or  embedded  feature)  must  be  both  (1)  indexed  to  the
issuer’s stock and (2) meet the

107

Table of Contents

requirements  of  the  equity  classification  guidance.  The  Company  determined  that  the  2026  Convertible  Notes  do  contain
embedded features indexed to its own stock, but do not meet the requirements for bifurcation, and therefore do not need to be
separately accounted for as an equity component. Since the embedded conversion feature meets the equity scope exception
from derivative accounting, and also since the embedded conversion option does not need to be separately accounted for as an
equity  component  under  ASC  470-20,  the  proceeds  received  from  the  issuance  of  the  convertible  debt  were  recorded  as  a
liability on the consolidated balance sheet.

Capped Call Transactions

In connection with the pricing of the 2026 Convertible Notes, the Company also paid $18.2 million to enter into privately
negotiated capped call transactions with one or more of the Option Counterparties. The capped call transactions are generally
expected to reduce the potential dilution upon conversion of the 2026 Convertible Notes in the event that the market price per
share of the Company’s common stock, as measured under the terms of the capped call transactions, is greater than the strike
price of the capped call transactions, which initially corresponds to the conversion price of the 2026 Convertible Notes, and is
subject to anti-dilution adjustments generally similar to those applicable to the conversion rate of the 2026 Convertible Notes.
The cap price of the capped call transactions will initially be $25.9263 per share, which represents a premium of approximately
75.0% over the last reported sale price of the Company’s common stock of $14.815 per share on April 14, 2020, and is subject
to certain adjustments under the terms of the capped call transactions.

The Company evaluated the capped call transactions under ASC 815-10 and determined that it should be accounted as
a separate transaction from the 2026 Convertible Notes and that the capped calls should be classified as equity instruments.
Therefore, the capped call premium paid in the amount of $18.2 million was recorded as a reduction to additional paid-in capital.
The capped calls will not be subsequently re-measured as long as the conditions for equity classification continue to be met.

The Company incurred $0.9 million of debt issuance costs relating to the issuance of the 2026 Convertible Notes, which
were recorded as a reduction to the notes on the consolidated balance sheet. The debt issuance costs is being amortized and
recognized as additional interest expense over the six-year contractual term of the notes using the effective interest rate method.

On February 29, 2016, the Company issued and sold $100.0 million aggregate principal amount of its 8.2% Convertible
Senior  Notes  (the  “2022  Convertible  Notes”)  and  received  total  net  proceeds  of  approximately  $99.2  million,  after  deducting
issuance  costs  of  $0.8  million.  The  2022  Convertible  Notes  constitute  general,  senior  unsubordinated  obligations  of  the
Company  and  are  guaranteed  by  certain  subsidiaries  of  the  Company.  The  2022  Convertible  Notes  bear  interest  at  a  fixed
coupon  rate  of  8.2%  per  annum  payable  quarterly  in  arrears  on  March  31,  June  30,  September  30  and  December  31  of
each  year,  which  commenced  on  March  31,  2016,  and  mature  on  March  31,  2022,  unless  earlier  converted,  redeemed  or
repurchased. If the Company fails to satisfy certain registration or reporting requirements, then additional interest will accrue on
the  2022  Convertible  Notes  at  a  rate  of  up  to  0.50%  per  annum  in  the  aggregate.  The  2022  Convertible  Notes  also  bear  a
premium  of  9%  of  their  principal  amount,  which  is  payable  when  the  2022  Convertible  Notes  mature  or  are  repurchased  or
redeemed by the Company.

The 2022 Convertible Notes were issued to Healthcare Royalty Partners III, L.P., for $75.0 million in aggregate principal
amount, and to three related party investors, KKR Biosimilar L.P., MX II Associates LLC, and KMG Capital Partners, LLC, for
$20.0 million, $4.0 million, and $1.0 million, respectively, in aggregate principal amount.

The 2022 Convertible Notes are convertible at the option of the holder at any time prior to the close of business on the
business  day  immediately  preceding  March  31,  2022  at  the  initial  conversion  rate  of  44.7387  shares  of  common  stock  per
$1,000 principal amount of 2022 Convertible Notes, which is equivalent to an initial conversion price of approximately $22.35 per
share, and is subject to adjustment in certain events. Upon conversion of the 2022 Convertible Notes by a holder, the holder will
receive shares of the Company’s common stock together, if applicable, with cash in lieu of any fractional share.

The 2022 Convertible Notes are redeemable in whole, and not in part, at the Company’s option on or after March 31,
2020,  if  the  last  reported  sale  price  per  share  of  common  stock  exceeds  160%  of  the  conversion  price  on  20  or  more
trading days during the 30 consecutive trading days preceding the date on which the Company sends notice of such redemption
to the holders of the 2022 Convertible Notes. At maturity or redemption, if not earlier converted, the Company will pay 109% of
the principal amount of the 2022 Convertible Notes maturing or being redeemed, together with accrued and unpaid interest, in
cash.

The  2022  Convertible  Notes  contain  customary  events  of  default  (as  defined  in  the  2022  Convertible  Note  purchase
agreement),  the  occurrence  of  which  could  result  in  the  acceleration  of  all  amounts  due  under  the  2022  Convertible  Notes.
These events of default include, among others, certain failures to pay amounts due on the 2022 Convertible Notes, to deliver the
consideration  due  upon  conversion  or  to  settle  uninsured  judgments,  decrees  or  orders  exceeding  $10.0  million,  and  certain
defaults  on  other  indebtedness  for  money  borrowed  of  at  least  $10.0  million,  insolvency-related  events  and  breaches  of
representations,  subject,  in  some  cases,  to  a  cure  period.  The  2022  Convertible  Notes  also  contain  covenants  restricting  the
Company’s ability to incur additional indebtedness for borrowed

109

    
 
 
 
 
 
 
 
 
Table of Contents

money or convertible preferred stock and to pay dividends or make distributions on the Company’s equity interests, subject to
certain  exceptions.  As  of  December  31,  2020,  the  Company  was  in  full  compliance  with  these  covenants  and  there  were  no
events of default under the 2022 Convertible Notes.

The  2022  Convertible  Notes  are  accounted  for  in  accordance  with  ASC  Subtopic  470-20,  Debt  with  Conversion  and
Other  Options.  Pursuant  to  ASC  Subtopic  470-20,  the  Company  evaluated  the  features  embedded  in  the  2022  Convertible
Notes and concluded that the embedded features are not required to be bifurcated and accounted for separately from the host
debt instrument.

The  Company  granted  the  holders  of  the  2022  Convertible  Notes  certain  registration  rights  requiring  the  Company  to
register, under the Securities Act of 1933, as amended, the resale of the shares of common stock issuable upon conversion or
settlement of the 2022 Convertible Notes.

On April 13, 2020, the Company entered into an amendment (the “Second Amendment”) to the 2022 Convertible Note
Purchase  Agreement,  dated  as  of  February  29,  2016  (the  “Note  Purchase  Agreement”),  which  amended  the  definition  of
Restricted Payment to exclude any payment (including a premium) to a counterparty under a Permitted Bond Hedge Transaction
(as defined in the Note Purchase Agreement). The Second Amendment also added to the Note Purchase Agreement a definition
of  Permitted  Bond  Hedge  Transaction,  with  such  definition  including  any  capped  call  option  (or  substantively  equivalent
derivative transaction) relating to the Company’s common stock purchased by it in connection with any issuance of indebtedness
or convertible indebtedness.

Term Loan

On January 7, 2019 (“the “Term Loan Closing Date”), the Company entered into a credit agreement (the “Term Loan”)
with affiliates of Healthcare Royalty Partners (together, the “Lender”). The Term Loan consists of a six-year term loan facility for
an aggregate principal amount of $75.0 million (the “Borrowings”). The obligations of the Company under the loan documents
are guaranteed by the Company’s material domestic U.S. subsidiaries.

The  Borrowings  under  the  Term  Loan  bear  interest  through  maturity  at  7.00%  per  annum  plus  three  month  LIBOR.
Pursuant to the terms of the Term Loan, the interest rate was reduced to 6.75% per annum plus LIBOR as of January 1, 2020 as
the  consolidated  net  sales  for  UDENYCA®  for  the  fiscal  year  ending  December  31,  2019  were  in  excess  of  $250.0  million.
Interest  is  payable  quarterly  in  arrears  and  varies  with  LIBOR.  The  Company  adopted  the  prospective  method  to  account  for
future cash payments. Under the prospective method, the effective interest rate is not constant, and any change in the expected
cash flows is recognized prospectively as an adjustment to the effective yield. As of December 31, 2020, the effective interest
rate is 10.47%.

The Company is required to pay principal on the Borrowings in equal quarterly installments beginning on the four year
anniversary of the Term Loan Closing Date (or, if consolidated net sales of UDENYCA® in the fiscal year ending December 31,
2021 are less than $375.0 million, beginning on the three year anniversary of the Term Loan Closing Date), with the outstanding
balance to be repaid on January 7, 2025, the maturity date.

The  Company  is  also  required  to  make  mandatory  prepayments  of  the  Borrowings  under  the  Term  Loan,  subject  to
specified  exceptions,  with  the  proceeds  of  asset  sales,  extraordinary  receipts,  debt  issuances  and  specified  other  events
including the occurrence of a change in control.

If all or any of the Borrowings are prepaid or required to be prepaid under the Term Loan, then the Company shall pay, in
addition to such prepayment, a prepayment premium equal to (i) with respect to any prepayment paid or required to be paid on
or prior to the three year anniversary of the Credit Agreement Closing Date, 5.00% of the Borrowings prepaid or required to be
prepaid,  plus  all  required  interest  payments  that  would  have  been  due  on  the  Borrowings  prepaid  or  required  to  be  prepaid
through  and  including  the  three  year  anniversary  of  the  Term  Loan  Closing  Date,  (ii)  with  respect  to  any  prepayment  paid  or
required to be paid after the three year anniversary of the Term Loan Closing Date but on or prior to the four year anniversary of
the  Term  Loan  Closing  Date,  5.00%  of  the  Borrowings  prepaid  or  required  to  be  prepaid,  (iii)  with  respect  to  any  prepayment
paid  or  required  to  be  paid  after  the  four  year  anniversary  of  the  Term  Loan  Closing  Date  but  on  or  prior  to  the  five  year
anniversary of the Term Loan Closing Date, 2.50% of the Borrowings prepaid or required to be prepaid, and (iv) with respect to
any prepayment paid or required to be prepaid thereafter, 1.25% of the Borrowings prepaid or required to be prepaid.

In connection with the Term Loan, the Company paid a fee to the Lender of approximately $1.1 million at closing in the
form of an original issue discount. Upon the prepayment or maturity of the Borrowings (or upon the date such prepayment or
repayment is required to be paid), it is required to pay an additional exit fee in an amount equal to 4.00% of the total principal
amount of the Borrowings.

The  obligations  under  the  Term  Loan  are  secured  by  a  lien  on  substantially  all  of  the  Company’s  and  its  Guarantors’
tangible and intangible property, including intellectual property. The Term Loan contains certain affirmative covenants, negative
covenants  and  events  of  default,  including,  covenants  and  restrictions  that  among  other  things,  restrict  the  ability  of  the
Company and its subsidiaries to, incur liens, incur additional indebtedness, make loans and investments, engage in mergers and
acquisitions,  in  asset  sales,  and  declare  dividends  or  redeem  or  repurchase  capital  stock.  Additionally,  the  consolidated  net
sales for UDENYCA® must not be lower than $70.0 million for the

fiscal year ending December 31, 2019, (b) $125.0 million for the fiscal year ending December 31, 2020, and (c) $150.0 million
for each fiscal year thereafter. A failure to comply with these covenants could permit the Lender under the Term Loan to declare
the Borrowings, together with accrued interest and fees, to be immediately due and payable.

On  April  13,  2020,  the  Company  entered  into  an  amendment  to  the  Term  Loan,  which  amended  the  Term  Loan’s
indebtedness covenant such that the Company could incur Convertible Bond Indebtedness (as defined in the credit agreement
governing  the  Term  Loan)  in  an  amount  not  to  exceed  the  greater  of  $230.0  million  or  20%  of  the  Company’s  market
capitalization.

The Company enters into contracts in the normal course of business with contract research organizations for preclinical
studies and clinical trials and CMO for the manufacture of drug materials. The contracts are cancellable, with varying provisions
regarding  termination.  If  a  contract  with  a  specific  vendor  were  to  be  terminated,  the  Company  would  only  be  obligated  for
products or services that the Company had received as of the effective date of the termination and any applicable cancellation
fees.

Contingencies

On March 3, 2017, Amgen filed an action against the Company, KBI BioPharma Inc., the Company’s employee Howard
S.  Weiser  and  Does  1-20  in  the  Superior  Court  of  the  State  of  California,  County  of  Ventura.  The  complaint  alleges  that  the
Company engaged in unfair competition and improperly solicited and hired certain former Amgen employees in order to acquire
and  access  trade  secrets  and  other  confidential  information  belonging  to  Amgen.  On  June  1,  2017,  Amgen  filed  a  Second
Amended  Complaint,  which  alleges  as  to  Coherus  (i)  unfair  competition  under  California  Business  and  Professions  Code
Section  17200  et  seq.,  (ii)  misappropriation  of  trade  secrets,  (iii)  aiding  and  abetting  breach  of  duty  of  loyalty  and  (iv)  tortious
interference  with  contract.  As  to  defendant  Weiser,  the  Second  Amended  Complaint  alleges  (i)  unfair  competition  under
California Business and Professions Code Section 17200 et seq., (ii) misappropriation of trade secrets, (iii) breach of contract,
(iv) violation of Penal Code Section 502 and (v) breach of duty of loyalty. KBI BioPharma Inc. is not named as a defendant in the
Second Amended Complaint. The Second Amended Complaint seeks injunctive relief and monetary damages. On May 2, 2019,
the Company and Amgen settled the trade secret action brought by Amgen. The details of the settlement are confidential but the
Company will continue to market UDENYCA® and began paying a mid-single digit royalty to Amgen for five years starting on
July 1, 2019.

Guarantees and Indemnifications

In  the  normal  course  of  business,  the  Company  enters  into  contracts  and  agreements  that  contain  a  variety  of
representations and warranties and provide for general indemnifications. The Company’s exposure under these agreements is
unknown because it involves claims that may be made against the Company in the future, but have not yet been made. To date,
the Company has not paid any claims or been required to defend any action related to its indemnification obligations. However,
the Company may record charges in the future as a result of these indemnification obligations. The Company would assess the
likelihood of any adverse judgments or related claims, as well as ranges of probable losses. In the cases where the Company
believes that a reasonably possible or probable loss exists, it will disclose the facts and circumstances of the claims, including
an estimate range, if possible.

10.

Leases

In July 2015, the Company entered into the office space for its corporate headquarters in Redwood City, California under
an  operating  lease  agreement,  which  has  been  subject  to  amendments  to  secure  additional  space  such  that  the  total
headquarters  leased  space  is  approximately  47,789  square  feet.  The  Lease  Agreement,  provides  for  certain  limited  rent
abatement  and  contains  annual  scheduled  rent  increases  over  the  lease  term.  The  lease  terminates  in  September 2024  and
contains a one-time option to extend the lease term for five years.

The Company also leases laboratory facilities in Camarillo, California. In October 2019, the Company entered into a new
laboratory facility lease (“New Camarillo Lease”) of approximately 25,017 square feet in a new location in Camarillo, California
as the current Camarillo

113

    
 
 
Table of Contents

leases terminated in June 2020 and December 2020. The New Camarillo Lease provides for certain limited rent abatement and
annual scheduled rent increases over the lease term. The lease commenced in January 2020 and terminates in May 2027, and
contains a one-time option to extend the lease term for five years.

The Company determined that the above facility leases were operating leases. The options to extend the lease terms for
these leases were not included as part of the right-of-use asset or lease liability as the Company was not reasonably certain it
would exercise those options.

In  2019,  the  Company  entered  into  a  vehicle  lease  agreement,  pursuant  to  which  it  currently  leases  42  vehicles.
Delivery  of  the  vehicles  commenced  during  the  first  quarter  of  2020.  The  term  of  each  leased  vehicle  commences  upon  the
delivery of the vehicle and is for a period of 36 months. The vehicles leased under this arrangement were classified as finance
leases.

In determining the present value of the lease payments, the Company used the incremental borrowing rate based on the
information available on January 1, 2019 (adoption date of ASC 842) for the leases that commenced prior to that date. For all
other leases, the Company used the incremental borrowing rate on the lease commencement or the lease modification date, as
applicable.

Stockholders’ Equity

Common Stock Offerings

In January 2016, the Company’s shelf registration statement on Form S-3 (File No. 333-208625) (the “Shelf Registration

Statement”) was declared effective by the SEC. As of January 18, 2019, the Company’s Shelf Registration Statement expired.

On October 28, 2016, the Company entered into a sales agreement (the “Sales Agreement”) with Cowen to sell shares
of the Company’s common stock, with aggregate gross sales proceeds of up to $100,000,000, from time to time, through an at-
the-market  equity  offering  program  under  which  Cowen  acted  as  its  sales  agent  (the  “ATM  Offering  Program”).  Cowen  was
entitled  to  compensation  for  its  services  equal  to  3.0%  of  the  gross  proceeds  of  any  shares  of  common  stock  sold  through
Cowen under the Sales Agreement. The Company had no obligation to sell any shares under the Sales Agreement, and could at
any time suspend solicitation and offers under the Sales Agreement. The shares were issued pursuant to the Company’s Shelf
Registration Statement. The Company filed a prospectus supplement, dated October 28, 2016, with the SEC in connection with
the offer and sale of the shares pursuant to the Sales Agreement. In 2018, the Company issued and sold 1,799,504 shares of
common  stock  at  a  weighted  average  price  of  $12.14  per  share  through  its  ATM  Offering  Program  and  received  total  gross
proceeds  of  $21.8  million.  After  deducting  commission  of  $0.7  million  and  offering  expense  of  $0.1  million,  the  net  proceeds
were  $21.0  million.  In  January  2019,  the  Company  issued  and  sold  761,130  shares  of  common  stock  at  a  weighted  average
price  of  $11.17  per  share  through  its  ATM  Program  and  received  total  gross  proceeds  of  $8.5  million.  After  deducting
commission  of  $0.3  million,  the  net  proceeds  were  $8.2  million.  As  of  January  18,  2019,  the  Company’s  Shelf  Registration
Statement expired and accordingly the ATM Offering Program was terminated.

In May 2018, the Company completed an underwritten public offering of 5,948,274 shares of its common stock at a price
to  the  public  of  $14.50  per  shares,  which  includes  the  closing  of  the  full  exercise  of  the  underwriters’  option  to  purchase  an
additional 775,861 shares of common stock. The Company received total gross proceeds from the offering of $86.3 million. After
deducting underwriting discounts and commissions of $5.2 million and offering expenses of $0.3 million, the net proceeds were
$80.8 million.

Stock Option Plans and Stock-Based Compensation

Equity Incentive Plans

In  October  2014,  the  Company’s  board  of  directors  and  its  stockholders  adopted  the  2014  Equity  Incentive  Plan  (the
“2014 Plan”), which became effective upon the closing of the Company’s IPO on November 6, 2014. The 2014 Plan is subject to
automatic annual increases in the number of shares available for issuance on the first business day of each fiscal year equal to
four percent (4%) of the number of shares of the Company’s common stock outstanding as of such date or a lesser number of
shares  as  determined  by  the  Company’s  board  of  directors.  All  remaining  shares  under  the  Company’s  2010  Stock  Plan  (the
“2010 Plan”) were transferred to the 2014 Plan upon adoption and any additional shares than would otherwise return to the 2010
Plan as a result of forfeiture, termination or expiration of the awards will return to the 2014 Plan. The 2014 Plan provided for the
Company to grant shares and/or options to purchase shares of common stock to employees, directors, consultants and other
service providers. As of December 31, 2020, the Company had 240,467 shares of common stock available for future issuance.

In June 2016, the Company adopted the 2016 Employment Commencement Incentive Plan (the “2016 Plan”). The 2016
Plan is designed to comply with the inducement exemption contained in Nasdaq’s Rule 5635(c)(4), which provides for the grant
of  non-qualified  stock  options,  restricted  stock  units,  restricted  stock  awards,  performance  awards,  dividend  equivalents,
deferred  stock  awards,  deferred  stock  units,  stock  payment  and  stock  appreciation  rights  to  a  person  not  previously  an
employee  or  director  of  the  Company,  or  following  a  bona  fide  period  of  non-employment,  as  an  inducement  material  to  the
individual’s  entering  into  employment  with  the  Company.  As  of  December  31,  2020,  the  Company  had  238,589  shares  of
common stock available for future issuance for new employees. The 2016 Plan does not provide for any annual increases in the
number of shares available.

options granted was $10.94, $9.52 and $7.77 per share, respectively, and the aggregate intrinsic value of options exercised was
$14.6 million, $10.3 million and $4.9 million, respectively.

The  Company  recognized  stock-based  compensation  expenses  of  $30.3  million,  $31.4  million  and  $33.3  million  for
the  years  ended  December  31,  2020,  2019  and  2018,  respectively,  related  to  stock  options.  As  of  December  31,  2020,  total
unrecognized  stock-based  compensation  expenses  related  to  unvested  employee  stock  options  was  $68.5  million,  which  is
expected to be recognized on a straight-line basis over a weighted-average period of approximately 2.6 years.

Restricted Stock Units

In August 2017, the Compensation Committee of the Company’s board of directors approved the granting of restricted
stock  units  (“RSUs”)  to  its  employees.  RSUs  are  share  awards  that  entitle  the  holder  to  receive  freely  tradable  shares  of  our
common stock upon vesting. The RSUs cannot be transferred and are subject to forfeiture if the holder’s employment terminates
prior to the release of the vesting restrictions. The Company’s RSUs generally vest over two to three years from the applicable
grant  date,  provided  the  employee  remains  continuously  employed  with  the  Company.  The  fair  value  of  RSUs  is  equal  to  the
closing price of our common stock on the applicable grant date of the RSUs.

$15.60, respectively.

The  Company  recognized  stock-based  compensation  expense  related  to  RSUs  of  $6.5  million,  $0.8  million  and  $0.7
million  for  the  years  ended  December  31,  2020,  2019  and  2018,  respectively.  As  of  December  31,  2020,  total  unrecognized
stock-based  compensation  expenses  related  to  unvested  RSUs  was  $12.6  million,  which  is  expected  to  be  recognized  on  a
straight-line basis over a weighted-average period of approximately 1.8 years.

Employee Stock Purchase Plan

In  October  2014,  the  Company’s  board  of  directors  and  its  stockholders  approved  the  establishment  of  the  2014
Employee  Stock  Purchase  Plan  (“ESPP”).  The  ESPP  provides  for  annual  increases  in  the  number  of  shares  available  for
issuance on the first business day of each fiscal year equal to the lesser of one percent (1%) of the number of shares of the
Company’s  common  stock  outstanding  as  of  such  date  or  a  number  of  shares  as  determined  by  the  Company’s  board  of
directors.  The  ESPP  had  2,752,449  shares  of  common  stock  available  for  future  issuance  as  of  December  31,  2020.  Eligible
employees may purchase common stock at 85% of the lesser of the fair market value of the Company’s common stock on the
first or last day of the offering period. The offering periods of ESPP are on May 16 and November 16. The Company recognized
stock-based  compensation  expenses  related  to  ESPP  of  $1.4  million,  $1.3  million  and  $0.8  million  for  the  years  ended
December  31,  2020,  2019  and  2018,  respectively.  As  of  December  31,  2020,  there  was  $0.7  million  of  unrecognized
compensation  expense  associated  with  the  ESPP,  which  is  expected  to  be  recognized  over  an  estimated  weighted-average
period of 4.5 months.

Valuation Assumptions of Awards Granted to Employees

The Company estimated the fair value of each stock option and awards granted under the ESPP on the date of grant
using  the  Black-Scholes  option-pricing  model.  The  following  table  illustrates  the  weighted  average  assumptions  for  the  Black-
Scholes option-pricing model used in determining the fair value of the awards during the years ended December 31, 2020, 2019
and 2018:

Expected  Term:  The  expected  term  represents  the  period  for  which  the  stock-based  awards  are  expected  to  be
outstanding and is based on the options’ vesting term and contractual term. The Company elected to use the “simplified method”
for estimating the expected term, which is calculated as the mid-point between the vesting period and the contractual term of the
options,  as  it  has  limited  historical  information  to  develop  expectations  about  future  exercise  patterns  and  post-vesting
employment termination behavior.

Expected  Volatility:  The  expected  volatility  for  the  years  ended  December  31,  2020  and  2019  is  based  on  the
Company’s historical stock price volatility. The expected volatility for the year ended December 31, 2018 is based on an average
historical stock price volatility of industry peers as the Company did not have sufficient trading history for its common stock in
those reporting periods.

Risk-Free  Interest  Rate:  The  Company  based  the  risk-free  interest  rate  by  using  an  equivalent  to  the  expected  term

based on the U.S. Treasury constant maturity rate as of the date of grant.

Expected Dividends: The Company has not paid and does not anticipate paying any dividends in the near future, and

therefore used an expected dividend yield of zero in the valuation model.

401(k) Retirement Plan

In  2019,  the  Company’s  Compensation  Committee  approved  the  Company’s  matching  of  the  employees  401(k) Plan
(the “401(k) Plan”) whereby eligible employees may elect to contribute up to the lesser of 90% of their annual compensation or
the  statutorily  prescribed  annual  limit  allowable  under  Internal  Revenue  Service  regulations.  The  Company  made  matching
contributions of 50% of the first $6,000 of each participant’s contributions into the 401(k) Plan during the years ended December
31, 2020 and 2019. The Company recorded compensation expense related to the match of $0.8 million for each of the years
ended December 31, 2020 and 2019.

Income  tax  provision  for  the  years  ended  December  31,  2020  and  2019  of  $3.5  million  and  $2.9  million,  respectively,
primarily relates to state taxes in jurisdictions outside of California, for which the Company has a limited operating history. There
was no income tax provision for the year ended December 31, 2018 due to the Company’s history of losses and valuation of
allowances against the deferred tax assets.

A reconciliation of the statutory U.S. federal rate to the Company’s effective tax rate is as follows:

ASC  740  (“ASC  740”)  requires  that  the  tax  benefit  of  net  operating  losses,  temporary  differences  and  credit  carry
forwards be recorded as an asset to the extent that management assesses that realization is “more likely than not.” Realization
of  the  future  tax  benefits  is  dependent  on  our  ability  to  generate  sufficient  taxable  income  within  the  carry  forward  period.
Because of our recent history of operating losses, management believes that recognition of the deferred tax assets arising from
the  above-mentioned  future  tax  benefits  is  currently  not  likely  (as  defined  in  ASC  740)  to  be  realized  and,  accordingly,  has
provided a valuation allowance. The valuation allowance decreased by $22.7 million and $13.4 million during the years ended
December 31, 2020 and 2019, respectively and increased by $54.6 million during the year ended December 31, 2018.

As of December 31, 2020, the Company had federal net operating loss carryforwards of approximately $430.3 million,
which will start to expire beginning in 2036, and various state net operating loss carryforwards of approximately $44.6 million,
which have various expiration dates beginning in 2031.

As of December 31, 2020, the Company had federal research and development credit carryforwards for federal income
tax  purposes  of  approximately  $48.2  million,  which  will  start  to  expire  in  2031,  and  state  research  and  development  credit
carryforwards of approximately $18.0 million, which can be carried forward indefinitely.

In assessing the realizability of deferred tax assets, the Company considers whether it is more likely than not that some
portion or all of the deferred tax assets will not be realized. The ultimate realization of deferred tax assets is dependent upon the
generation  of  future  taxable  income  during  the  periods  in  which  the  temporary  differences  representing  net  future  deductible
amounts  become  deductible.  Due  to  the  weight  of  the  negative  evidence,  which  is  primarily  its  history  of  losses  outweighing
other positive evidence, the Company has determined that it is more likely than not that its federal net deferred tax assets and
certain state net deferred tax assets will not be realized, and therefore, the federal and certain state net deferred tax assets are
fully offset by a valuation allowance at December 31, 2020 and 2019. The deferred tax assets were primarily comprised of net
operating losses, tax credit carryforwards and stock-based compensation. Utilization of the net operating loss carryforwards and
credits may be subject to a substantial annual limitation due to the ownership change limitations provided by Section 382 of the
Internal Revenue Code of 1986, as amended, and similar state provisions. The annual limitation may result in the expiration of
net  operating  losses  and  credits  before  utilization.  Under  the  new  enacted  tax  law,  the  carry  forward  period  of  net  operating
losses generated from 2018 forward is indefinite. However, the carryforward period for net operating losses generated prior to
2018  remains  the  same.  Therefore,  the  annual  limitation  may  result  in  the  expiration  of  certain  net  operating  losses  and  tax
credit carryforwards before their utilization.

The Company files U.S. California and other state income tax returns with varying statutes of limitations. The tax years

from 2011 forward remain open to examination due to the carryover of unused net operating losses and tax credits.

As  of  December  31,  2020,  2019  and  2018,  the  Company  had  approximately  $13.2  million,  $11.6  million  and  $18.1
million,  respectively,  of  unrecognized  benefits,  none  of  which  would  currently  affect  the  Company’s  effective  tax  rate  if
recognized due to the Company’s deferred tax assets being fully offset by a valuation allowance. The Company does not believe
there  will  be  any  material  changes  in  its  unrecognized  tax  positions  over  the  next  twelve  months.  During  the  years  ended
December 31, 2020, 2019 and 2018 the Company did not recognize accrued interest and penalties related to unrecognized tax
benefits. The Company does not anticipate a material adjustment of unrecognized tax benefits during the next 12 months that
impacts the rate for tax positions of prior years.

A prior member of the Company’s board of directors is also the president and chief executive officer of Medpace Inc.
(“Medpace”). As such, Medpace was deemed to be a related party until the director’s resignation on March 1, 2018. As a result,
the Company no longer reflects balances and transactions associated with Medpace as related party in its consolidated financial
statements  as  of  March  1,  2018.  The  Company  recognized  $1.5  million  during  year  ended  December  31,  2018  for  services
rendered by Medpace within research and development expense in the consolidated statements of operations.

Convertible Notes — Related Parties

In  February  2016,  the  Company  issued  Convertible  Notes  to  certain  related  parties  (some  companies  affiliated  with
members of the Company’s board of directors), for an aggregate principal amount of $25.0 million (see Note 8 for related party
disclosure).

InteKrin Acquisition

In  February  2014,  the  Company  completed  the  acquisition  of  the  InteKrin  for  total  consideration  of  $5.0  million.
Mr.  Dennis  M.  Lanfear,  the  chief  executive  officer  of  the  Company,  was  the  chairman  of  the  board  and  acting  president  of
InteKrin at the time of the acquisition. As such, the InteKrin acquisition was a related party transaction. Mr. Lanfear also owned
10% of the outstanding securities of InteKrin Russia, a majority owned subsidiary of InteKrin.

In September 2018, InteKrin acquired the outstanding 17.5% of securities of InteKrin Russia held by its non-controlling
owners for $0.7 million. As a result of this purchase of the non-controlling ownership in InteKrin Russia, Mr. Lanfear, who was
one of the non-controlling stockholders of InteKrin Russia, received $0.4 million in consideration for his shares.

16.        Subsequent Events

On February 1, 2021, the Company  entered into an Exclusive License and Commercialization Agreement (the 

“Collaboration Agreement”) with Junshi Biosciences for the co-development and commercialization of toripalimab, Junshi 
Biosciences’ anti-PD-1 antibody in the United States and Canada. 

Under  the  terms  of  the  Collaboration  Agreement,  the  Company  will  pay  $150.0  million  upfront  for  exclusive  rights  to
toripalimab  in  the  United  States  and  Canada,  options  in  these  territories  to  Junshi  Biosciences’  anti-TIGIT  antibody  and  next-
generation  engineered  IL-2  cytokine,  and  certain  negotiation  rights  to  two  undisclosed  preclinical  immuno-oncology  drug
candidates. The Company will have the right to conduct all commercial activities of toripalimb in the United States and Canada.
The  Company  will  be  obligated  to  pay  Junshi  Biosciences  a  20%  royalty  on  net  sales  of  toripalimab  and  up  to  an
aggregate  $380.0  million  in  one-time  payments  for  the  achievement  of  various  milestones,  including  up  to  $290.0  million  for
attainment of certain sales thresholds. If the Company exercise its options, it will be obligated to pay an option exercise fee for
each of the anti-TIGIT antibody and the IL-2 cytokine of $35.0 million per program. Additionally, for each exercised option, the
Company will be obligated to pay Junshi Biosciences an 18% royalty on net sales and up to an aggregate $255.0 million for the
achievement  of  various  milestones,  including  up  to  $170.0  million  for  attainment  of  certain  sales  thresholds.  Under  the
Collaboration Agreement, the Company retains the right to collaborate in the development of toripalimab and the

122

other licensed compounds, and will pay for a portion of these co-development activities up to a maximum of $25.0 million per
licensed compound per year.

Closing of the Collaboration Agreement is subject to clearance under the Hart-Scott Rodino Antitrust Improvements Act

(the “HSR Act”).

In  connection  with  the  Collaboration  Agreement,  the  Company  entered  into  a  stock  purchase  agreement  (the  “Stock
Purchase Agreement”) with Junshi Biosciences agreeing, subject to customary conditions, to acquire certain equity interests in
the Company. Pursuant to the Stock Purchase Agreement, the Company has agreed to issue 2,491,988 unregistered shares of
its common stock, at a price per share of $20.0643, for an aggregate value of approximately $50.0 million, to Junshi Biosciences
as a portion of the consideration for the Collaboration.

Item 9A.   Controls and Procedures

(a)     Evaluation of Effectiveness of Disclosure Controls and Procedures

We carried out an evaluation, under the supervision of our Chief Executive Officer and our Chief Financial Officer, and
evaluated the effectiveness of our disclosure controls and procedures as defined in Rules 13a-15(e) and 15d-15(e) under the
Exchange Act, as of the end of the period covered by this Annual Report on Form 10-K. Based on that evaluation, our President
and  Chief  Executive  Officer  and  our  Chief  Financial  Officer  have  concluded  that,  as  of  the  end  of  the  period  covered  by  this
Annual Report on Form 10-K, our disclosure controls and procedures were, in design and operation, effective.

We maintain disclosure controls and procedures that are designed to ensure that information required to be disclosed in
our Exchange Act reports is recorded, processed, summarized and reported within the time periods specified in the Securities
and Exchange Commission’s rules and forms and that such information is accumulated and communicated to our management,
including our chief executive officer, principal financial officer and principal accounting officer, as appropriate, to allow for timely
decisions regarding required disclosure.

We intend to review and evaluate the design and effectiveness of our disclosure controls and procedures on an ongoing
basis  and  to  correct  any  material  deficiencies  that  we  may  discover.  Our  goal  is  to  ensure  that  our  management  has  timely
access to material information that could affect our business. While we believe the present design of our disclosure controls and
procedures is effective to achieve our goal, future events affecting our business may cause us to modify our disclosure controls
and procedures. In designing and evaluating the disclosure controls and procedures, management recognizes that any controls
and procedures, no matter how well designed and operated, can provide only reasonable assurance of achieving the desired
control  objectives,  and  management  is  required  to  apply  its  judgment  in  evaluating  the  cost-benefit  relationship  of  possible
controls and procedures.

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

Our  management  is  responsible  for  establishing  and  maintaining  adequate  internal  control  over  financial  reporting,  as
such  term  is  defined  in  Exchange  Act  Rules  13a-15(f).  Under  the  supervision  and  with  the  participation  of  our  management,
including our principal executive officer, principal financial officer and principal accounting officer, we 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. Ernst & Young LLP, our independent registered public
accounting firm, has attested to and issued a report on the effectiveness of our internal control over financial reporting, which is
included herein.

Report of Independent Registered Public Accounting Firm

To the Stockholders and the Board of Directors of Coherus BioSciences, Inc.

Opinion on Internal Control Over Financial Reporting

We  have  audited  Coherus  BioSciences,  Inc.’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,  Coherus  BioSciences,  Inc.  (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 Coherus BioSciences, Inc. as of December 31, 2020 and 2019, and the related
consolidated  statements  of  operations,  comprehensive  income  (loss),  stockholders’  equity  (deficit)  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  25,  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

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.

PURSUANT TO
SECTION 13a-14(a) OR 15d-14(a) OF THE SECURITIES EXCHANGE ACT OF 1934
AS ADOPTED PURSUANT TO
SECTION 302 OF THE SARBANES-OXLEY ACT OF 2002

Exhibit 31.1

I, Dennis M. Lanfear, certify that:

1.

2.

3.

4.

I have reviewed this Annual Report on Form 10-K of Coherus BioSciences, Inc. (the "registrant");

Based on my knowledge, this report does not contain any untrue statement of a material fact or omit to state a material
fact necessary to make the statements made, in light of the circumstances under which such statements were made,
not misleading with respect to the period covered by this report;

Based on my knowledge, the financial statements, and other financial information included in this report, fairly present
in all material respects the financial condition, results of operations and cash flows of the registrant as of, and for, the
periods presented in this report;

The registrant’s other certifying officer(s) and I are responsible for establishing and maintaining disclosure controls and
procedures (as defined in Exchange Act Rules 13a-15(e) and 15d-15(e)) and internal control over financial reporting
(as defined in Exchange Act Rules 13a-15(f) and 15d-15(f)) for the registrant and have:

(a) Designed  such  disclosure  controls  and  procedures,  or  caused  such  disclosure  controls  and  procedures  to  be
designed  under  our  supervision,  to  ensure  that  material  information  relating  to  the  registrant,  including  its
consolidated  subsidiaries,  is  made  known  to  us  by  others  within  those  entities,  particularly  during  the  period  in
which this report is being prepared;

(b) Designed such internal control over financial reporting, or caused such internal control over financial reporting to
be designed under our supervision, 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;

(c) Evaluated the effectiveness of the registrant’s disclosure controls and procedures and presented in this report our
conclusions  about  the  effectiveness  of  the  disclosure  controls  and  procedures,  as  of  the  end  of  the  period
covered by this report based on such evaluation; and

(d) Disclosed in this report any change in the registrant’s internal control over financial reporting that occurred during
the registrant’s most recent fiscal quarter (the registrant’s fourth fiscal quarter in the case of an annual report) that
has  materially  affected,  or  is  reasonably  likely  to  materially  affect,  the  registrant’s  internal  control  over  financial
reporting; and

5.

The registrant’s other certifying officer(s) and I have disclosed, based on our most recent evaluation of internal control
over  financial  reporting,  to  the  registrant’s  auditors  and  the  audit  committee  of  the  registrant’s  board  of  directors  (or
persons performing the equivalent functions):

(a) All  significant  deficiencies  and  material  weaknesses  in  the  design  or  operation  of  internal  control  over  financial
reporting which are reasonably likely to adversely affect the registrant’s ability to record, process, summarize and
report financial information; and

(b) Any fraud, whether or not material, that involves management or other employees who have a significant role in

the registrant’s internal control over financial reporting.

4.

I have reviewed this Annual Report on Form 10-K of Coherus BioSciences, Inc. (the "registrant");

Based on my knowledge, this report does not contain any untrue statement of a material fact or omit to state a material
fact necessary to make the statements made, in light of the circumstances under which such statements were made,
not misleading with respect to the period covered by this report;

Based on my knowledge, the financial statements, and other financial information included in this report, fairly present
in all material respects the financial condition, results of operations and cash flows of the registrant as of, and for, the
periods presented in this report;

The registrant’s other certifying officer(s) and I are responsible for establishing and maintaining disclosure controls and
procedures (as defined in Exchange Act Rules 13a-15(e) and 15d-15(e)) and internal control over financial reporting
(as defined in Exchange Act Rules 13a-15(f) and 15d-15(f)) for the registrant and have:

(a) Designed  such  disclosure  controls  and  procedures,  or  caused  such  disclosure  controls  and  procedures  to  be
designed  under  our  supervision,  to  ensure  that  material  information  relating  to  the  registrant,  including  its
consolidated  subsidiaries,  is  made  known  to  us  by  others  within  those  entities,  particularly  during  the  period  in
which this report is being prepared;

(b) Designed such internal control over financial reporting, or caused such internal control over financial reporting to
be designed under our supervision, 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;

(c) Evaluated the effectiveness of the registrant’s disclosure controls and procedures and presented in this report our
conclusions  about  the  effectiveness  of  the  disclosure  controls  and  procedures,  as  of  the  end  of  the  period
covered by this report based on such evaluation; and

(d) Disclosed in this report any change in the registrant’s internal control over financial reporting that occurred during
the registrant’s most recent fiscal quarter (the registrant’s fourth fiscal quarter in the case of an annual report) that
has  materially  affected,  or  is  reasonably  likely  to  materially  affect,  the  registrant’s  internal  control  over  financial
reporting; and

5.

The registrant’s other certifying officer(s) and I have disclosed, based on our most recent evaluation of internal control
over  financial  reporting,  to  the  registrant’s  auditors  and  the  audit  committee  of  the  registrant’s  board  of  directors  (or
persons performing the equivalent functions):

(a) All  significant  deficiencies  and  material  weaknesses  in  the  design  or  operation  of  internal  control  over  financial
reporting which are reasonably likely to adversely affect the registrant’s ability to record, process, summarize and
report financial information; and

(b) Any fraud, whether or not material, that involves management or other employees who have a significant role in

the registrant’s internal control over financial reporting.
