Item 1. Business.

OVERVIEW

We are a clinical-stage, research and development biotechnology company focused on developing novel immunotherapeutic candidates for the treatment of
different forms of cancer. We have developed two versatile and enabling platform technologies for rational design of precision immune modulatory drugs.
Our lead clinical candidate, APVO436, and preclinical candidates, ALG.APV-527 and APVO603, were developed using our ADAPTIR™ modular protein
technology platform. Our preclinical candidate APVO442 was developed using our ADAPTIR-FLEX™ modular protein technology platform.  

The  versatile  and  robust  ADAPTIR  and  ADAPTIR-FLEX  platforms  are  designed  to  generate  monospecific,  bispecific,  and  multispecific  antibody
candidates that are capable of enhancing the human immune system against cancer cells. ADAPTIR and ADAPTIR-FLEX are both modular platforms,
which  gives  us  the  flexibility  to  generate  immunotherapeutic  candidates  with  a  variety  of  mechanisms  of  action.  This  flexibility  in  design  allows  us  to
potentially generate novel therapeutic candidates that may provide the foundation for the establishment of effective strategies against difficult to treat, as
well as advanced forms cancer. We have successfully designed and constructed numerous investigational-stage prototype product candidates based on our
ADAPTIR platform. The ADAPTIR platform technology is designed to generate monospecific and bispecific immunotherapeutic proteins that specifically
bind  to  one  or  more  targets,  for  example,  bispecific  therapeutic  molecules,  which  may  have  structural  and  functional  advantages  over  monoclonal
antibodies. The structural differences of ADAPTIR molecules over monoclonal antibodies allow for the development of ADAPTIR immunotherapeutics
that are designed to engage immune effector cells and disease targets in a novel manner to produce unique signaling responses and ultimately kill tumors or
modulate the immune system to kill tumors.

We are skilled at candidate generation, validation, and subsequent preclinical and clinical development using the ADAPTIR platform and have added the
ADAPTIR-FLEX platform to generate multi-specific candidates or other candidates to our platform capabilities.  We have developed preclinical candidates
based on the ADAPTIR-FLEX platform which are advancing in our pipeline. We are developing our ADAPTIR and ADAPTIR-FLEX molecules by way
of our protein engineering, preclinical development, process development, and clinical development capabilities.

Prior  to  February  28,  2020,  we  had  one  marketed  product,  IXINITY,  indicated  in  adults  and  children  12  years  of  age  and  older  with  Hemophilia  B  for
control and prevention of bleeding episodes, and management of bleeding during operations. On February 28, 2020, Aptevo entered into an LLC Purchase
Agreement  with  Medexus  Pharmaceuticals  Inc.  (Medexus),  pursuant  to  which  Aptevo  sold  all  of  the  issued  and  outstanding  limited  liability  company
interests of Aptevo BioTherapeutics LLC (Aptevo BioTherapeutics), a subsidiary of Aptevo which wholly owned the IXINITY and related Hemophilia B
business. As a result of the transaction, Medexus obtained all rights, title and interest to the IXINITY product and intellectual property. In addition, Aptevo
BioTherapeutics personnel responsible for the sale and marketing of IXINITY also transitioned to Medexus as part of the transaction.  

As consideration for the sale, at closing Aptevo received an amount equal to $30 million in cash. In addition to the payment received at closing, Aptevo
receives deferred payments based on quarterly net sales of IXINITY and may also earn milestones from Medexus in the future. The parties also agreed that
Aptevo would provide transition services for a limited period of time.

Recent Developments

On  November  6,  2020,  Tang  Capital  Partners  LP,  Tang  Capital  Management,  LLC  and  Kevin  Tang  (collectively,  “Tang”)  jointly  filed  a  statement  on
Schedule 13D to report that Tang had purchased 1,760,000 shares of our common stock, representing approximately 54% of our issued and outstanding
shares of common stock as of the date of filing such Schedule 13D.  As of the date of this Annual Report on Form 10-K, Tang has subsequently been
diluted  to  a  39.6%  beneficial  ownership  position,  primarily  through  the  exercise  of  certain  warrants  that  were  issued  and  outstanding  prior  to  Tang
acquiring  its  ownership  position  in  Aptevo.  Additionally,  on  November  18,  2020,  our  Board  received  a  written  unsolicited,  non-binding  indication  of
interest from Tang, proposing to acquire all of the outstanding shares of our common stock not already beneficially owned by Tang for $50.00 per share in
cash,  subject  to  confirmatory  due  diligence  conducted  under  a  customary  non-disclosure  agreement  (the  “Initial  Proposal”).  We  have  had  a  series  of
communications during which we attempted to negotiate a non-disclosure agreement with Tang to permit discussions covering our nonpublic information
and our operations. Further, on February 9, 2021, Tang announced its intention to nominate two candidates for election to our board of directors at our 2021
annual meeting of stockholders and submitted an advisory stockholder proposal for consideration at our 2021 annual meeting to commence a process to sell
Aptevo to the highest bidder (the “Tang Stockholder Proposals”). We have incurred and may continue to incur additional expenses by retaining the services
of various professionals to advise us on responding to these matters.

The  Aptevo  Board  was  open  to  exploring  the  indication  of  interest  from  Tang  and  made  earnest  efforts  to  evaluate  it.  However,  it  was  unable  to  do  so
because it was unable to reach agreement with Tang on the terms of a customary non-disclosure agreement, including limitations on the use of confidential
information  by  Tang.    Had  agreement  on  the  terms  of  a  non-disclosure  agreement  been  reached,  it  would  have  permitted  the  exchange  of  confidential
information and would have enabled both parties to conduct due diligence.  In this early stage of the Company’s development, the Aptevo Board believes it
is difficult for the market to accurately value the potential of Aptevo’s proprietary platform technologies and therapeutic candidates, which have just begun
to demonstrate their effectiveness and potentially life-saving capabilities to the Company’s patients, shareholders and other stakeholders. The Board will
continue to carefully evaluate any indications of interest and proposals for strategic transactions that it receives from current shareholders or otherwise, in
line with its fiduciary duties and commitment to acting in the best interests of all of the Company’s shareholders.

On  March  30,  2021,  the  Company  entered  into  and  closed  a  royalty  purchase  agreement  (the  Royalty  Purchase  Agreement)  with  an  entity  managed  by
HealthCare Royalty Management, LLC (HCR) pursuant to which the Company sold to HCR the right to receive all royalty payments made by Pfizer Inc.
(Pfizer) in respect of net sales of RUXIENCE. Under the terms of the agreement, the Company received $35 million (the Investment Amount) at closing
and the Company is eligible to receive additional payments in aggregate of up to an additional $32.5 million based on the achievement of sales milestones
in  2021,  2022,  and  2023  (collectively,  the  Milestone  Amounts).  The  Royalty  Purchase  Agreement  further  provides  that,  once  HCR  reaches  aggregate
royalty payments totaling 190% of the Investment Amount plus the Milestone Amounts to the extent paid by HCR to the Company, Aptevo will be entitled
to receive 50% of any additional royalty payments by Pfizer thereafter.

2

 
 
 
 
In  connection  with  the  Royalty  Purchase  Agreement,  we  amended  our  Credit  Agreement  with  MidCap  Financial  and used $10  million  of  the  proceeds
received from the Royalty Purchase Agreement with HCR to pay down the outstanding principal under this agreement from $25 million to $15 million.

STRATEGY

We seek to grow our business by, among other things:

Advancing our ADAPTIR and ADAPTIR-FLEX platforms, initially focusing on immunotherapy and the development of novel bispecific and
multispecific proteins for the treatment of cancer. We focus on product development using our ADAPTIR and ADAPTIR-FLEX platforms. We plan to
generate additional bispecific protein immunotherapies for early development, potentially with other collaborative partners, to further validate the potential
of the ADAPTIR and ADAPTIR-FLEX platforms. We intend to favor the development of bispecific candidates that have the potential to demonstrate proof
of concept early in development and are differentiated in key oncology indications. We expect to continue to expand the ADAPTIR and ADAPTIR-FLEX
product pipelines to address areas of unmet medical need. Our goal is to generate monospecific, bispecific, and multispecific ADAPTIR and ADAPTIR-
FLEX  proteins  to  target  tumors  using  the  immune  system  or  direct  cytokine  delivery  to  selective  cell  populations  or  modulate  immune  cells  to  treat
diseases. We believe these product candidates may have utility in oncology and other therapeutic areas.

Continuing  to  develop  new  products.  We  are  committed  to  new  product  development.  We  have  expertise  in  molecular  biology,  antibody
engineering  and  the  development  of  protein  therapeutics,  including  cell  line  development,  protein  purification,  process  development  and  analytical
characterization.  We  believe  that  these  core  areas  of  expertise  enable  the  development  of  therapeutics  based  on  the  ADAPTIR  and  ADAPTIR-FLEX
platform technologies from design, pre-clinical testing, and clinical development to preparation of a biologics license application, or BLA.

Establishing collaborative partnerships to broaden our pipeline and provide funding for research and development.  We  intend  to  continue  to
develop  and  grow  our  product  portfolio  through  internal  research  and  development  as  well  as  through  collaborations  with  other  biotechnology  and
pharmaceutical companies, academia, and non-governmental organizations.

Platform Technology

ADAPTIR  and  ADAPTIR-FLEX  Platform  Technologies.  The  ADAPTIR  and  ADAPTIR-FLEX  platform  technologies  can  be  used  to  produce
monospecific,  bispecific,  and  multispecific  immunotherapeutic  proteins.  These  protein  candidates  bind  to  one  or  more  targets  found  on  tumor  cells,
immune cells, or other cells in the body or circulation to either amplify, suppress, or regulate the body’s defense mechanisms to treat cancer. We focus on
developing  drugs  for  treatment  of  oncology  indications,  but  also  may  pursue  other  indications  including  autoimmune  diseases.  We  believe  we  are  well
positioned for the development of monospecific, bispecific, or multispecific therapeutics, which are antibody-based molecules that are able to bind one or
more  targets  of  therapeutic  interest,  utilizing  our  innovative  ADAPTIR  (modular  protein  technology)  and  ADAPTIR-FLEX  platform  technology.  This
allows us to take a novel approach to cancer immunotherapy or for treatment of other diseases.

Structurally, ADAPTIR and ADAPTIR-FLEX molecules are similar to antibodies; they can exhibit the same biological functions of an antibody,
but can be easily modified to either eliminate or incorporate new activities, all the while maintaining a similar size, stability, half-life and manufacturing
advantages  of  a  monoclonal  antibody.  The  ADAPTIR  molecules  are  single-chain  polypeptides  comprising  customized  elements,  including  a  protein
domain  that  binds  to  one  or  more  targets  connected  to  the  hinge  domain  and  a  set  of  antibody  constant  domains  known  as  the  fragment  crystallizable
region, or Fc region of a human antibody. A second protein domain can be connected to the Fc region using a linker.  The antibody Fc region can elicit an
immune response by binding to the corresponding Fc receptors found on various immune cells such as natural killer (NK) cells, and other cells bearing Fc
receptors to mediate antibody-dependent cell cytotoxicity resulting in killing the target. With the ADAPTIR platform, the Fc region can be modified to
enhance or eliminate these functions. Incorporation of the Fc region into the ADAPTIR platform also provides for an extended serum half-life by engaging
recycling via the neonatal Fc receptor or FcRn. A long serum half-life could potentially reduce dosing frequency and dose quantity. The ADAPTIR-FLEX
molecules are comprised of at least two polypeptides that are comprised of customized elements similar to ADAPTIR candidates. The Fc region of these
molecules can be modified to enable formation of a stable heterodimer. These candidates have similar mutations in the Fc region as ADAPTIR candidates
to enable or eliminate binding to Fc receptors, but retaining binding to FcRn to provide for an extended serum half-life.  

The ADAPTIR platform technology enables the design of both monospecific and bispecific bi-valent protein therapeutics.

Bispecific ADAPTIR molecules are similar in structure to monospecific ADAPTIR molecules, with the exception that they have two customized
target binding domains on the ends of the Fc region. We have created several bispecific molecules that are able to redirect T-cell cytotoxicity (RTCC). T-
cells are white blood cells that fight infections and tumor cells. RTCC ADAPTIR molecules are designed to activate T-cells to specifically kill a tumor. The
RTCC ADAPTIR does so by binding to a common component CD3, a receptor complex that activates T cells, when engaging a specific tumor antigen on a
specific tumor via the second binding domain, thereby activating the T-cell to kill the tumor.

4

 
Our ADAPTIR-FLEX platform technology extends advantages of ADAPTIR technology to create protein therapeutics with varied specificity and

valency and potentially new modes of action.

ADAPTIR-FLEX molecules are composed of two different polypeptides that form a dimer through modifying specific sequences in the Fc region
of each polypeptide. Each end of the polypeptide may contain one or two different binding domains, enabling the ADAPTIR-FLEX molecules to bind up to
four  targets.  In  addition,  the  ADAPTIR-FLEX  platform  can  be  used  to  modify  the  valency  of  binding  to  each  target,  which  means  it  can  bind  a  target,
through one binding domain or through multiple binding domains, to a specific target to enable modifying the strength of binding to a specific target.  

We  believe  that  ADAPTIR  and  ADAPTIR-FLEX  are  promising  platform  technologies  within  the  rapidly  growing  field  of  immuno-oncology
therapeutics. The structural differences between ADAPTIR and ADAPTIR-FLEX molecules and monoclonal antibodies allow for the development of new
immunotherapeutics that engage disease targets in a novel manner and produce a unique signaling response. By customizing the binding domains of our
molecules, we can select the desired potency, half-life, toxicity and stability/manufacturability. We have the potential to develop products with mechanisms
of  action  including,  but  not  limited  to,  RTCC,  modulating  signals  through  immunostimulatory  or  immunoinhibitory  receptors  and  targeted  cytokine
delivery. We can expand our ADAPTIR and ADAPTIR-FLEX platforms to generate monospecifics, bispecifics, or multispecifics that target tumor antigens
in combination with costimulatory molecules, including TNF-Receptor family members and other activating or inhibitory signaling receptors. We believe
the  ADAPTIR  and  ADAPTIR-FLEX  platform  technologies  may  prove  to  have  advantages  over  other  immunotherapeutics  and  other  bispecific  T-cell
engaging technologies. In pre-clinical studies, we gathered data indicating that APVO436, a RTCC ADAPTIR bispecific that binds CD123, may have high
potency and activity at low doses, a long half-life, and reduced cytokine release compared to other bispecifics targeting the same tumor antigens and CD3.
The  ADAPTIR  and  ADAPTIR-FLEX  monospecifics,  bispecifics,  and  multispecifics  can  be  produced  using  standard  manufacturing  practices.  Further
clinical and pre-clinical studies may not confirm or establish the anticipated benefits of this platform.

Our ADAPTIR and ADAPTIR-FLEX platform intellectual property (IP) portfolio consists of IP that we solely own and control, with the exception
of  non-exclusive  licenses  to  Chinese  hamster  ovary  (CHO)  cell  lines  and  related  expression  systems,  and  a  non-exclusive  license  to  certain  transgenic
rodents  of  Open  Monoclonal  Technology,  Inc.’s  OmniAb  platform,  which  we  non-exclusively  license  from  various  third  parties.    See  “Intellectual
Property” for additional information about the ownership rights to ADAPTIR and ADAPTIR-FLEX platform intellectual property.

Product Portfolio

Our current product candidate pipeline is summarized in the table below:

Product Candidates

Our  pipeline  includes  investigational  clinical  and  pre-clinical  stage  anti-cancer  drug  candidates  with  clinical  impact  potential  for  treating  both

hematologic malignancies, also known as “liquid” tumors, and solid tumor cancers.

APVO436. a recombinant, bispecific T-cell engaging antibody candidate built on Aptevo’s proprietary ADAPTIR protein therapeutic platform, is

designed to simultaneously target CD123 and CD3 and redirect T-cell cytotoxicity to the tumor.

APVO436 is currently being evaluated in a Phase 1/1b open-label, dose-escalation clinical trial in the United States involving patients with AML
and MDS.  In the current Phase 1a trial, patients receive APVO436 by intravenous dosing up to six 28-day cycles. The objective of the trial is to evaluate
safety,  pharmacokinetics,  and  pharmacodynamics  of  APVO436  in  patients.    Phase  1  will  consist  of  up  to  60  patients  and  is  designed  to  determine  the
recommended  dose  for  Phase  1b.    The  primary  endpoint  for  Phase  1  is  designed  to  be  the  identification  of  a  maximally  tolerated  dose  (MTD),  as  the
incidence of dose-limiting toxicities (DLT’s) occurring during Cycle 1 of each dose cohort.  

Phase  1b  is  designed  to  further  evaluate  the  safety  and  tolerability  of  APVO436  as  well  as  assess  its  clinical  activity  as  a  single  agent  at  the
recommended  Phase  2  dose  (RP2D)  level.  The  Phase  1b  portion  of  the  study  will  include  efficacy  endpoints,  including  but  not  limited  to  the  overall
response rate.

To  date,  enrollment  in  cohorts  1  through  9  has  been  completed  and  enrollment  in  cohort  10  is  ongoing.  We  have  observed,  as  signs  of  clinical
activity,  stabilization  of  leukemia,  a  response  that  consequently  deepened  to  partial  remission  and  complete  remission  (CR)  in  two  difficult  to  treat
relapsed/refractory AML patients. Preliminary data regarding APVO436, indicated that two patients in cohort 6 of the APVO436 clinical trial achieved
complete  remission.  The  first  patient  is  no  longer  in  a  complete  remission  status  but  is  continuing  therapy,  while  the  second  patient  progressed  and
discontinued therapy. Most patients have either completed their dose regimens or have discontinued dosing without a dose-limiting toxicity.

6

 
 
One of the most significant and frequent side effects associated with the use bispecific, T-cell engaging antibodies are neurologic toxicities. For
example, approximately 65 percent of patients treated with Blinatumomab (a bispecific antibody approved for an oncologic indication, sold under the brand
name Blincyto, targeting the leukemia-associated CD19 antigen found on acute lymphoblastic leukemia (ALL) cells and redirecting CD3 antigen-carrying
T-cells  against  these  leukemia  cells)  experienced  neurologic  toxicities,  most  frequently  dizziness,  tremor,  confusional  state,  and  encephalopathy.
Neurological toxicities may be severe, life-threatening, or fatal. Grade 3 or higher neuropsychiatric toxicity has occurred in approximately 15 percent of
patients  treated  with  Blinatumomab,  including  encephalopathy,  seizures,  speech  disorders,  disturbance  of  consciousness,  confusion,  disorientation,  and
coordination and balance disorders. Use of dexamethasone is the standard of care for neurotoxicity. Our preliminary data indicates that serious neurologic
toxicity is not a frequent complication associated with APVO436 treatment.

Another potential complication associated with treatment using bispecific, T-cell engaging antibodies is a systemic inflammatory syndrome known
as Cytokine Release Syndrome (CRS). CRS may occur within minutes to hours after infusion of the bispecific T-cell engaging antibody or emerge as a
delayed  onset  complication  after  several  days.  Clinical  manifestations  of  CRS  may  range  from  mild  to  severe  including  hypotension,  hypoxia,  and
uncontrolled  systemic  inflammatory  response  with  circulatory  collapse,  vascular  leakage,  peripheral  and/or  pulmonary  edema,  renal  failure,  cardiac
dysfunction, and fatal multiorgan system failure.  Heart failure can also be a consequence of the systemic inflammatory syndrome of CRS.  Another form
of  systemic  inflammation  a  bispecific  T-cell  engaging  antibody  can  cause  is  Hemophagocytic  Lymphohistiocytosis  (HLH)/Macrophage  Activation
Syndrome (MAS) which shares many clinical and laboratory features with CRS.  HLH/MAS is considered a form of CRS when it occurs after treatment
with a bispecific T-cell engaging antibody.  

CRS have occurred in some APVO436 patients, which have been effectively treated using the generally recommended standard CRS treatment,
which includes the use of tocilizumab and dexamethasone, combined with standard supportive care. This has been confirmed effective in the APVO436
patients that have experienced CRS.   Several additional treatments for CRS have recently become available, and we are working with key opinion leaders
and site investigators to further optimize our algorithm for addressing CRS.

On November 26, 2019, the FDA granted Orphan Drug Designation for AML to APVO436, which grants us exclusive marketing and development

rights, as well as eligibility for market exclusivity upon FDA approval of APVO436.

ALG.APV-527.  a  novel  investigational  bispecific  ADAPTIR  candidate,  developed  in  partnership  with  Alligator  Bioscience  AB  (Alligator),
featuring a novel mechanism of action designed to simultaneously target 4-1BB (CD137) and 5T4, a tumor antigen overexpressed in a number of different
types of cancer. 4-1BB, a costimulatory receptor on T cells, is known to enhance the immune response to cancer through activation of tumor-specific T
cells and is believed to be a promising target for new immunotherapeutic approaches. ALG.APV-527 could potentially have utility in the treatment of a
broad spectrum of cancers over-expressing the 5T4 tumor antigen, including mesothelioma, non-small-cell-lung, head and neck, pancreatic, renal, ovarian
and bladder cancers. Aptevo and Alligator plan to file a clinical trial application (CTA) in Europe in 2021 and to subsequently commence first in human
dosing in the fourth quarter of 2021.

APVO603.  a  preclinical  dual  agonist  bispecific  ADAPTIR  candidate  employing  a  novel  mechanism  of  action  to  simultaneously  target  4-1BB
(CD137) and OX40 (CD134), both members of the TNF-receptor family.  Dual targeting of 4-1BB and OX40 provides synergistic co-stimulation of T cells
with the potential to amplify the cytotoxic function of activated T cells and NK cells, potentially leading to more robust anti-tumor responses. APVO603’s
combined  activation  of  both  the  4-1BB  and  OX40  TNF  receptors  represents  an  attractive  approach  in  potentially  overcoming  the  suppressive  tumor
microenvironment. The targeted co-stimulation of 4-1BB and OX40 has the potential to promote an important immunological cascade, enhancing T-cell
activation, prolonging T-cell survival, and improving tumor killing. This product candidate is not dependent on any one tumor antigen and has the potential
to treat multiple solid tumors. Additionally, we are initiating IND-enabling studies and CMC activities to support IND submission in 2022.

7

 
APVO442.  a  novel  bispecific  candidate  based  on  the  ADAPTIR-FLEX  platform  technology  that  binds  to  PSMA  with  two  identical  binding
domains to PSMA and with one binding domain to CD3 with reduced binding affinity. This candidate was designed to increase biodistribution of drugs to
PSMA  positive  tumors  for  treatment  of  prostate  cancer.  The  low-affinity  single  binding  domain  to  CD3  has  the  potential  to  allow  for  increased
concentrations  at  the  tumor  due  to  possibly  reducing  absorption  of  a  drug  by  circulating  peripheral  T  cells.    Preclinical  studies  have  been  completed
demonstrating in vitro RTCC that is directed to PSMA bearing tumor cell lines in vitro and in vivo animal models.

Competition

We  face,  and  will  continue  to  face,  intense  competition  from  both  U.S.-based  and  foreign  producers  of  both  large  and  small  molecule
immunotherapeutic  products,  some  of  which  have  lower  cost  structures,  greater  access  to  capital,  greater  resources  for  research  and  development,  and
sophisticated marketing capabilities. Any product candidate that we successfully develop and commercialize is likely to compete with currently marketed
products, as well as other novel product candidates that are in development for the same indications.

APVO436:  We  anticipate  that  APVO436  would  compete  with  other  agents  targeting  CD123  that  are  in  development  if  they  are  also  approved.
Bispecifics in development targeting CD123 include: flotetuzumab (formerly MGD006, Macrogenics), JNJ-63709178 (Janssen) and vibecotamab (formerly
XmAb14045,  Xencor).  There  are  numerous  CAR-T  therapies  in  development:  CART123  (University  of  Penn.),  CARTCD123  (NCI/City  of  Hope),
UCART123 (Cellectis), MB-102 (Mustang Bio) and several others in development in China. Other competitive products targeting CD123 are: tagraxofusp
(formerly SL-401, an antibody immunotoxin, Stemline), KHK2833 (monoclonal antibody, Kyowa Hakko Kirin Pharma), CSL362 (monoclonal antibody,
CSL/Janssen) and IMGN632 (ImmunoGen and Jazz Pharmaceuticals).

ALG.APV-527:  This asset targets 4-1BB in a bispecific format when cross-linked with the tumor antigen 5T4.  We anticipate that ALG.APV-527
would  compete  with  bispecifics  targeting  5T4  and  4-1BB  which  are  currently  in  preclinical  development  (Crescendo  Biologics  and  Macrogenics).  In
addition,  other  competitors  include  bispecifics  targeting  4-1BB  in  combination  with  other  targets  such  as  4-1BB  x  FAP  (FAP  is  expressed  on  tumor
associated stomal fibroblasts).  4-1BB x FAP is currently in  phase  1  clinical  development  by  Molecular  Partners  and  Amgen  for  treatment  of  epithelial
cancers. Another bispecific targets 4-1BB x HER (PRS343) which is in phase 1 clinical development by Pieris for treatment of breast cancer.

Furthermore, we face significant competition in the oncology market in general, including from: AbbVie Inc., Aduro, Inc., Affirmed, Amgen Inc.,
AnaptysBio,  Inc.,  Astellas  Pharma  Inc.,  Bayer  AG,  Biogen  Idec  Inc.,  Boehringer  Ingelheim  GmbH,  F-Star  Biotechnology  Ltd.,  Genentech  Inc.  (a
subsidiary  of  F.  Hoffmann-La  Roche  Ltd.),  Genmab  A/S,  GlaxoSmithKline  plc,  Grifols  USA  LLC,  Bristol  Myers  Squibb,  ImmunoGen,  Inc.,
Immunomedics, Inc., Janssen BioTech Inc., Johnson & Johnson, Macrogenics, Inc., Novartis International AG, Pieris Pharmaceuticals, Inc., Sanofi-Aventis
US  LLC,  Takeda  Pharmaceuticals  U.S.A.,  Inc.,  Teneobio  Inc.,  Xencor,  Inc.  and  Zymeworks  Biopharmaceuticals,  Inc.  Additionally,  there  may  be  other
potential competitors or companies developing competitive products that may not be known to us at this time.

COLLABORATIONS WITH ALLIGATOR BIOSCIENCE

On July 20, 2017, our wholly owned subsidiary Aptevo Research and Development LLC (Aptevo R&D), entered into a collaboration and option
agreement  (the  Collaboration  Agreement)  with  Alligator  Bioscience  AB,  (Alligator),  pursuant  to  which  Aptevo  R&D  and  Alligator  are  collaboratively
developing  ALG.APV-527,  a  lead  bispecific  antibody  candidate  simultaneously  targeting  4-1BB  (CD137),  a  member  of  the  TNFR  superfamily  of  a
costimulatory receptor found on activated T-cells, and 5T4 a tumor antigen overexpressed in a number of different types of cancer. This product candidate
is built on our novel ADAPTIR platform. 

Subject  to  certain  exceptions  for  Aptevo  R&D’s  manufacturing  and  platform  technologies,  the  parties  will  jointly  own  intellectual  property
generated  in  the  performance  of  the  development  activities  under  the  Collaboration  Agreement.  Under  the  terms  of  the  Collaboration  Agreement,  the
parties intend to share revenue received from a third-party commercialization partner equally, or, if the development costs are not equally shared under the
Collaboration Agreement, in proportion to the development costs borne by each party.

8

 
The  Collaboration  Agreement  also  contains  several  points  in  development  at  which  either  party  may  elect  to  “opt-out”  (i.e.,  terminate  without
cause) and, following a termination notice period, cease paying development costs for this product candidate, which would be borne fully by the continuing
party. Following an opt-out by a party, the continuing party will be granted exclusive rights to continue the development and commercialization of this
product candidate, subject to a requirement to pay a percentage of revenue received from any future commercialization partner for this product, or, if the
continuing party elects to self-commercialize, tiered royalties on the net sales of this product by the continuing party ranging from the low to mid-single
digits, based on the point in development at which the opt-out occurs. The parties have also agreed on certain technical criteria or “stage gates” related to
the  development  of  this  product  that,  if  not  met,  will  cause  an  automatic  termination  and  wind-down  of  the  Collaboration  Agreement  and  the  activities
thereunder, provided that the parties do not agree to continue.

The Collaboration Agreement contains industry standard termination rights, including for material breach following a specified cure period, and in

the case of a party’s insolvency.

IXINITY

IXINITY (coagulation factor IX (recombinant)). IXINITY is a third-generation recombinant human coagulation factor IX approved by the FDA
in April 2015 in the United States for the control and prevention of bleeding episodes and for perioperative management in adults and children 12 years of
age or older with hemophilia B. Hemophilia B, also known as Christmas disease, is a rare, inherited bleeding disorder. The blood of hemophilia B patients
has an impaired clotting ability, which results from substantially reduced or missing factor IX activity. Patients with hemophilia B commonly experience
joint  bleeding  with  pain  and  swelling,  which  can  result  in  irreversible  joint  damage.  They  may  also  experience  more  serious  or  life-threatening
hemorrhages.  People  with  hemophilia  B  require  factor  IX  injections  to  restore  normal  blood  coagulation  temporarily.  Many  patients  use  regular,
prophylactic treatment to try to prevent bleeding episodes, while others use on-demand treatment to control bleeding episodes after they occur. Treatment
selection and approach is individualized based on factors including the patient’s condition and age, factor level severity, bleeding pattern, activity level and
individual pharmacokinetic parameters.

On  February  28,  2020,  we  entered  into  an  LLC  Purchase  Agreement  with  Medexus,  pursuant  to  which  Aptevo  sold  all  of  the  issued  and
outstanding  limited  liability  company  interests  of  Aptevo  BioTherapeutics,  a  subsidiary  of  Aptevo  wholly  owns  IXINITY  and  related  Hemophilia  B
business. As a result of the transaction, Medexus obtained all rights, title and interest to the IXINITY product and intellectual property. In addition, Aptevo
BioTherapeutics personnel responsible for the sale and marketing of IXINITY also transitioned to Medexus as part of the transaction.

INTELLECTUAL PROPERTY

We  rely  on  a  combination  of  patents,  trademarks,  trade  secrets,  and  nondisclosure  and  non-competition  agreements  to  protect  our  proprietary
intellectual property and will continue to do so. We own or exclusively license the patents and patent applications in our patent portfolio that support the
ADAPTIR-FLEX  platform,  ADAPTIR  platform  and  pipeline  products,  including  APVO436,  with  the  exception  of  certain  cell  line  rights  and  other
research tools, which we license on a non-exclusive basis. We practice patent life cycle management by filing patent applications to protect new inventions
relating to meaningful improvements to our products and related methods. We primarily seek patent protection for inventions that support our products and
product candidates, but from time to time, we may seek patent protection for inventions that could, for instance, support a potential business opportunity or
block a competitor from designing around our existing patents.

In general, and where possible, we pursue patent protection in countries where we believe there will be a significant market for the corresponding
product or product candidate. We generally do not seek patent protection in countries where we have reason to believe we would not be able to enforce
patents. For instance, we tend to not file in countries that are frequently listed on the Priority Watch List of the Special 301 Report prepared by the Office of
the United States Trade Representative, with the exception that we typically file patent applications in China, Russia and India. We may also decide to take
a narrower filing approach for secondary and improvement type inventions as compared to inventions that are more foundational to our products. We do
not seek patent protection in countries that are on the United Nations, or U.N., list of Least Developed Countries.

9

 
The  term  of  protection  for  various  patents  associated  with,  and  expected  to  be  associated  with,  our  marketed  product  and  product  candidates  is
typically twenty years from the filing date, but may vary depending on a variety of factors, including the date of filing of the patent application or the date
of patent issuance and the legal term of patents in the countries in which they are obtained. The protection afforded by a patent varies on a product-by-
product  basis  and  country-to-country  basis  and  depends  upon  many  factors,  including  the  type  of  patent,  the  scope  of  its  coverage,  the  availability  of
regulatory-related  extensions,  the  necessity  for  terminal  disclaimers,  the  availability  of  legal  remedies  in  a  particular  country,  and  the  validity  and
enforceability of the patents.

In  some  cases,  we  may  decide  that  the  best  way  to  protect  our  intellectual  property  is  to  retain  proprietary  information  as  trade  secrets  and
confidential  information,  rather  than  to  apply  for  patents,  which  would  involve  disclosure  of  proprietary  information  to  the  public.  When  determining
whether  to  protect  intellectual  property  as  a  trade  secret,  we  consider  many  factors  including,  for  instance,  our  ability  to  maintain  the  trade  secret,  the
likelihood that a competitor will independently develop the information, our ability to patent protect the intellectual property and the likelihood we would
be able to enforce a resulting patent.

We  are  a  party  to  a  number  of  license  agreements  under  which  we  license  patents,  patent  applications,  and  other  intellectual  property.  These
agreements  impose  various  commercial  diligence  and  financial  payment  obligations  on  us.  We  expect  to  continue  to  enter  into  these  types  of  license
agreements in the future.

ADAPTIR and ADAPTIR-FLEX Platforms. We protect the ADAPTIR platform technology through a combination of patents and trade secrets.
We own all ADAPTIR and ADAPTIR-FLEX platform intellectual property, with the exception that we have licenses to certain intellectual property related
to  third  party  research  tools  that  we  use  in  conjunction  with  our  ADAPTIR  platform  technology  such  as  cell  lines,  vectors,  expression  systems,  and
transgenic rodents.  For instance, we have a non-exclusive commercial license and research license with Lonza Group AG (Lonza) related to its CHO cell
lines and vectors. Under our Lonza research license, we have an option to take a license to use the GS System to develop and manufacture therapeutic
proteins for our commercial purposes. We also have a non-exclusive license to certain transgenic rodents of Open Monoclonal Technology, Inc.’s OmniAb
platform.  

The  initial  version  of  the  ADAPTIR  platform  technology  was  originally  developed  by  Trubion  Pharmaceuticals,  Inc.  (Trubion)  prior  to  its
acquisition by Emergent. A patent family supporting use of unique linkers in the homodimer (a molecule consisting of two identical halves) version of the
ADAPTIR  platform  was  invented  jointly  by  Trubion  and  Wyeth  Pharmaceuticals,  Inc.  (Wyeth)  as  part  of  a  collaboration  between  the  two  companies.
Wyeth  assigned  the  rights  it  had  in  that  platform  patent  family  to  Trubion.  We  subsequently  acquired  the  rights  to  the  platform  patent  family  upon  our
spinoff from Emergent.

In order to differentiate our platform inventions from antibodies and other antibody-like constructs that have been publicly disclosed, many of our

patents and patent applications are directed to unique aspects or components of our platform such as linkers, targets, or binding domains.

We  have  patents  relating  to  the  ADAPTIR  platform  issued  in  the  United  States,  Australia,  Israel,  Japan,  South  Korea,  Mexico,  Malaysia,  New
Zealand, Philippines, Russia, Singapore, South Africa, and Vietnam. We also have applications pending in various territories including Europe and Brazil.
We plan to continue to improve our ADAPTIR platform and to file patent applications on those improvements. Our decision as to where to file any new
ADAPTIR  improvement  inventions  will  be  based  in  part  on  the  significance  of  the  improvement.  If  patents  issue  on  the  pending  ADAPTIR  patent
applications, the patent term for those patents are estimated to expire between 2027 and 2036.  As our ADAPTIR platform technology evolves, we may
decide to allow patent applications and patents to expire if they contain claims that are limited to aspects of the platform that are no longer of value to
Aptevo.  

ADAPTIR-FLEX, our heterodimer platform, is covered by a pending United States provisional patent application.  We anticipate filing a patent
application under the Patent Cooperation Treaty (PCT) in 2021. The PCT patent application will allow us to file patent applications in PCT member state
countries including, for instance, the United States, Europe, Japan, China, Australia, and Canada. If patents claiming priority to the pending ADAPTIR-
FLEX patent application are issued, the resulting patents are estimated to expire in 2041.

We own patent families directed to use of particular binding domains in the ADAPTIR and ADAPTIR-FLEX platforms.  For instance, we have
some patents that cover the use of an ADAPTIR therapeutic to target CD3.  We also have pending patent applications that cover ADAPTIR therapeutics
containing our preferred humanized CD3 binding domain polypeptide sequences.  

10

 
APVO436. We nationalized our core patent family, which covers the APVO436 product candidate in various countries and territories including the
U.S.,  Australia,  Brazil,  Canada,  China,  Colombia,  Europe,  Eurasia,  India,  Indonesia,  Israel,  Japan,  Malaysia,  Mexico,  New  Zealand,  Philippines,
Singapore, South Africa, South Korea, Ukraine, and Vietnam.

ALG.APV-527. We co-own with Alligator a patent family corresponding to PCT application PCT/EP2018/069850, which covers the ALG.APV-
527 product candidate. In January and February of 2020, this patent family was nationalized in various countries. Aptevo and Alligator also co-own U.S.
patent 10,239,949, which relates to protein molecules that specifically bind to 5T4 and/or 4-1BB.  

In  addition  to  the  co-owned  assets,  Alligator  owns  a  patent  family  corresponding  to  PCT  application  PCT/EP2017/059656,  which  also  covers

ALG.APV-527. Aptevo has an exclusive license from Alligator to this patent family for the development of the ALG.APV-527 product candidate.

Pre-Clinical  Therapeutic  Candidates.  We  routinely  file  United  States  provisional  patent  applications  and/or  Patent  Cooperation  Treaty  (PCT)
patent  applications  on  our  pre-clinical  therapeutic  assets  when  we  believe  we  have  sufficient  data  to  support  a  patent  application  filing.   Aptevo  owns
pending patent applications, for instance, which support its APVO603 and APVO442 therapeutic candidates.

Trademarks owned by Aptevo Therapeutics Inc. and its subsidiaries. Where possible, we pursue registered trademarks for our marketed products
in  significant  markets.  We  own  trademark  registrations  and  pending  applications  for  the  marks:  APTEVO  THERAPEUTICS,  APTEVO
BIOTHERAPEUTICS, APTEVO RESEARCH AND DEVELOPMENT, the Aptevo logo, ADAPTIR, and ADAPTIR-FLEX in relevant jurisdictions.

REGULATION

Regulations  in  the  United  States  and  other  countries  have  a  significant  impact  on  our  product  development,  manufacturing,  and  marketing
activities. Government authorities in the United States, at the federal, state, and local level, and in other countries, extensively regulate, among other things,
the  research,  development,  testing,  approval,  manufacture,  packaging,  storage,  recordkeeping,  labeling,  advertising,  promotion,  distribution,  marketing,
import, and export of biopharmaceutical products. In addition, sponsors of biopharmaceutical products participating in Medicaid and Medicare are required
to comply with mandatory price reporting, discount, and rebate requirements. The processes for obtaining regulatory approvals in the United States and in
foreign countries, along with compliance with applicable statutes and regulations, require the expenditure of substantial time and financial resources. In the
United States, the FDA regulates biopharmaceutical products under the Federal Food, Drug, and Cosmetic Act, or FDCA, the Public Health Services Act,
or  PHSA,  and  their  implementing  regulations.  FDA’s  requirements  and  expectations  with  respect  to  product  development  are  constantly  evolving.  By
example,  in  light  of  the  COVID-19  pandemic,  the  FDA  issued  a  number  of  guidance  documents  to  assist  companies  navigating  COVID-19,  product
development, and manufacturing.

Product Development for Therapeutics

Pre-clinical Testing. Before beginning testing of any compounds with potential therapeutic value in human subjects in the United States, stringent
government requirements for pre-clinical data must be satisfied. Pre-clinical testing includes both in vitro, or in an artificial environment outside of a living
organism, and in vivo, or within a living organism, laboratory evaluation and characterization of the safety and efficacy of a drug and its formulation, as
well as its chemistry, pharmacology, and toxicity. We perform pre-clinical testing on all of our product candidates before we initiate any human trials.

Investigational  New  Drug  Application.  Before  clinical  testing  may  begin,  the  results  of  pre-clinical  testing,  together  with  manufacturing
information, analytical data and any other available clinical data or literature, must be submitted to the United States Food and Drug Administration, or
FDA,  as  part  of  an  Investigational  New  Drug  Application,  or  IND.  The  sponsor  must  also  include  an  initial  protocol  detailing  the  first  phase  of  the
proposed  clinical  investigation,  together  with  information  regarding  the  qualifications  of  the  clinical  investigators.  The  provided  data  must  provide  an
adequate basis for evaluating both the safety and the scientific rationale for the initial clinical studies in human volunteers. The IND automatically becomes
effective 30 days after receipt by the FDA unless the FDA imposes a clinical hold within that 30-day time period. In such a case, the IND sponsor and the
FDA must resolve any outstanding concerns before the clinical trial can begin. Clinical holds also may be imposed by the FDA at any time before or during
trials due to safety concerns or non-compliance. As a result, submission of an IND may not result in FDA authorization to commence a clinical trial.

11

 
Clinical Trials. Clinical trials involve the administration of the drug to healthy human volunteers, or to patients with the target disease or disorder
under  the  supervision  of  a  qualified  physician  (also  called  an  investigator)  pursuant  to  an  FDA-reviewed  protocol.  Human  clinical  trials  typically  are
conducted in three sequential phases, although the phases may overlap with one another. Clinical trials must be conducted under protocols that detail the
objectives of the study, the parameters to be used to monitor safety and the efficacy criteria, if any, to be evaluated. Each protocol, and any subsequent
amendments, must be submitted to the FDA, as part of the IND, or comparable foreign regulatory authorities.

•

•

•

•

Phase  1  clinical  trials  test  for  safety,  dose  tolerance,  absorption,  bio-distribution,  metabolism,  excretion,  structure  activity  relationships,
mechanism of action, and clinical pharmacology and, if possible, for early evidence regarding efficacy. Phase 1 studies may be conducted
in  healthy  human  volunteers  or  patients  with  the  target  disease  or  condition.  Phase  1a  is  typically  a  dose  escalation  trial.  Phase  1b  may
involve cohort expansion at one or more dose levels to determine the recommended Phase 2 dose.
Phase 2 clinical trials are controlled studies that involve a small sample of individuals with the target disease or disorder and seek to assess
the efficacy of the drug for specific targeted indications to determine dose response and the optimal dose range and dose regimen and to
gather additional information relating to safety and potential adverse effects.
Phase  3  clinical  trials  are  adequate  and  controlled  studies  that  consist  of  expanded,  large-scale  studies  of  patients,  at  geographically
dispersed sites, with the target disease or disorder to obtain definitive statistical evidence of the efficacy and safety of the proposed product
and dosing regimen. The safety and efficacy data generated from Phase 3 clinical trials typically form the basis for FDA or comparable
foreign regulatory authorities approval of the product candidate, as well as product labeling. Typically, two Phase 3 trials are required by
the FDA for product approval. Under some limited circumstances, however, the FDA may approve a BLA based upon a single Phase 3
clinical study plus confirmatory evidence or a single large multicenter trial without confirmatory evidence.
Phase  4  clinical  trials,  if  conducted,  are  conducted  after  a  product  has  been  approved.  These  trials  can  be  conducted  for  a  number  of
purposes, including to collect long-term safety information or to collect additional data about a specific population. As part of a product
approval, the FDA or comparable foreign regulatory authorities may require that certain Phase 4 studies, which are called post-marketing
commitment  studies,  be  conducted  post-approval.    The  results  of  Phase  4  studies  can  confirm  or  refute  the  effectiveness  of  a  product
candidate, and can provide important safety information.

Additional  kinds  of  data  may  also  help  to  support  a  BLA  or  product  development,  such  as  patient  experience  and  real  world  evidence.    For
appropriate indications sought through supplemental BLAs, data summaries may provide marketing application support. For genetically targeted products
and variant protein targeted products intended to address an unmet medical need in one or more patient subgroups with a serious or life threatening rare
disease or condition, the FDA may allow a sponsor to rely upon data and information previously developed by the sponsor or for which the sponsor has a
right  of  reference,  that  was  submitted  previously  to  support  an  approved  application  for  a  product  that  incorporates  or  utilizes  the  same  or  similar
genetically  targeted  technology  or  a  product  that  is  the  same  or  utilizes  the  same  variant  protein  targeted  drug  as  the  product  that  is  the  subject  of  the
application.

In addition, under the Pediatric Research Equity Act of 2003, or PREA, BLAs and supplements for a new active ingredient, indication, dosage
form, dosage regimen, or route of administration must contain data to assess the safety and efficacy of the product for the claimed indications in all relevant
pediatric subpopulations and to support dosing and administration for each pediatric subpopulation for which the product is safe and effective. The FDA
may grant deferrals for submission of data or full or partial waivers. Unless otherwise required by regulation, PREA does not apply to any drug or biologic
for an indication for which orphan designation has been granted for the relevant indication.

Good Clinical Practice. All of the phases of clinical studies must be conducted in conformance with the FDA’s Good Clinical Practices (GCPs) or
equivalent  standards  from  comparable  foreign  regulatory  authorities,  which  are  ethical  and  scientific  quality  standards  for  conducting,  recording  and
reporting clinical trials to assure that the data and reported results are credible and accurate and that the rights, safety and well-being of trial participants are
protected.  GCPs  include  requirements  that  all  research  subjects  provide  their  informed  consent  in  writing  for  their  participation  in  any  clinical  trial.
Investigators must also provide certain information to the clinical trial sponsors to allow the sponsors to make certain financial disclosures to the FDA. In
addition, an Institutional Review Board, or IRB, at each study site participating in the clinical trial or a central IRB must review and approve the plan for
any clinical trial, informed consent forms, and communications to study subjects before a study commences at

12

 
 
 
 
 
that site. An IRB considers, among other things, whether the risks to individuals participating in the trials are minimized and are reasonable in relation to
anticipated benefits, and whether the planned human subject protections are adequate. The IRB must continue to oversee the clinical trial while it is being
conducted. Once an IND is in effect, each new clinical protocol and any amendments to the protocol must be submitted to the IND for FDA review, and to
the IRB for approval. If a product candidate is being investigated for multiple intended indications, separate INDs may also be required. Progress reports
detailing the results of the clinical trials must also be submitted at least annually to the FDA and the IRB and more frequently if serious adverse events or
other significant safety information is found.

Information about certain clinical trials, including a description of the study and study results, must be submitted within specific timeframes to the
National Institutes of Health, or NIH, for public dissemination on their clinicaltrials.gov website. Sponsors or distributors of investigational products for the
diagnosis, monitoring, or treatment of one or more serious diseases or conditions must also have a publicly available policy on evaluating and responding
to requests for expanded access requests.

The manufacture of investigational biologics for the conduct of human clinical trials is subject to FDA’s current Good Manufacturing Practice, or
cGMP  requirements.  Investigational  biologics  and  therapeutic  substances  imported  into  the  United  States  are  also  subject  to  regulation  by  the  FDA.
Further, the export of investigational products outside of the United States is subject to regulatory requirements of the receiving country as well as U.S.
export requirements under the FDCA.

Concurrent  with  clinical  trials,  companies  usually  complete  additional  animal  studies  and  must  also  develop  additional  information  about  the
chemistry  and  physical  characteristics  of  the  product  candidate  as  well  as  finalize  a  process  for  manufacturing  the  product  in  commercial  quantities  in
accordance with cGMP requirements. The manufacturing process must be capable of consistently producing quality batches of the product candidate and,
among other things, manufacturers must develop methods for testing the identity, strength, quality, potency, and purity of the final product. Additionally,
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 shelf life.

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. 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 if the trial poses
an unexpected serious harm to subjects. The FDA or an IRB may also impose conditions on the conduct of a clinical trial. Clinical trial sponsors may also
choose to discontinue clinical trials as a result of risks to subjects, a lack of favorable results, or changing business priorities.

Marketing Approval - Biologics

Biologics  License  Application.  All  data  obtained  from  a  comprehensive  development  program,  including  research  and  product  development,
manufacturing, pre-clinical and clinical trials, labeling and related information are submitted in a biologics license application, or BLA, to the FDA and in
similar  regulatory  filings  with  the  corresponding  agencies  in  other  countries  for  review  and  approval.  In  most  cases,  the  submission  of  a  marketing
application is subject to a substantial application user fee. These user fees must be paid at the time of the first submission of the application, even if the
application is being submitted on a rolling basis. Fee waivers or reductions are available in certain circumstances.  By example, product candidates that are
designated as orphan products, which are further described below, are not subject to application user fees unless the application includes an indication other
than the orphan indication.

The submission of an application is not a guarantee that the FDA will find the application complete and accept it for filing. The FDA may refuse to
file the application and request additional information rather than accept the application for filing, in which case the application must be resubmitted with
the  supplemental  information.  The  resubmitted  application  is  also  subject  to  review  before  the  FDA  accepts  it  for  filing.  The  FDA  has  two  months  to
review an application for its acceptability for filing.

13

 
Once  an  application  is  accepted  for  filing,  the  FDA  begins  an  in-depth  substantive  review.    The  Prescription  Drug  User  Fee  Act,  or  PDUFA,
establishes a two-tiered review system: Standard Review and Priority Review. When conducting Priority Review, the FDA has a goal to review and act on
BLA submissions within six months from the date of the FDA’s acceptance for filing of the application, rather than the ten-month goal under a Standard
Review. The FDA gives Priority Review status to product candidates that provide safe and effective therapies where no satisfactory alternative exists or to a
product candidate that are intended to treat serious conditions and, if approved, would provide significant improvements in the safety or effectiveness of the
treatment, diagnosis, or prevention of the serious condition. The PDUFA date is only a goal, thus, the FDA does not always meet its PDUFA dates. The
review  process  and  the  PDUFA  date  may  also  be  extended  if  the  FDA  requests  or  the  sponsor  otherwise  provides  substantial  additional  information  or
clarification regarding the submission.

The FDA may refer certain applications to an advisory committee. Before approving a product candidate for which no active ingredient (including
any ester or salt of active ingredients) has previously been approved by the FDA, the FDA must either refer that product candidate to an external advisory
committee or provide in an action letter, a summary of the reasons why the FDA did not refer the product candidate to an advisory committee. The FDA
may also refer other product candidates to an advisory committee if FDA believes that the advisory committee’s expertise would be beneficial. An advisory
committee is typically a panel that includes clinicians and other experts, which review, evaluate, and make 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.

The FDA reviews applications to determine, among other things, whether a product candidate meets the agency’s approval standards and whether
the manufacturing methods and controls are adequate to assure and preserve the product’s identity, strength, quality, potency, and purity. Before approving
a marketing application, the FDA typically will inspect the facility or facilities where the product is manufactured, referred to as a Pre-Approval Inspection.
The  FDA  will  not  approve  an  application  unless  it  determines  that  the  manufacturing  processes  and  facilities,  including  contract  manufacturers  and
subcontractors,  are  in  compliance  with  cGMP  requirements  and  adequate  to  assure  consistent  production  of  the  product  within  required  specifications.
Additionally, before approving a marketing application the FDA will inspect one or more clinical trial sites to assure compliance with GCPs.

In  reviewing  a  BLA,  the  FDA  may  grant  approval  or  deny  the  application  through  a  complete  response  letter,  or  CRL,  if  it  determines  the
application does not provide an adequate basis for approval requesting additional information. A CRL indicates that the review cycle of the application is
complete and the application is not ready for approval and describes all of the specific deficiencies that the FDA identified. A CRL generally contains a
statement  of  specific  conditions  that  must  be  met  in  order  to  secure  final  approval  of  the  marketing  application,  and  may  require  additional  clinical  or
preclinical testing in order for the FDA to reconsider the application. The deficiencies identified may be minor, for example, requiring labeling changes; or
major, for example, requiring additional clinical trials. If a CRL is issued, the applicant may either: resubmit the marketing application, addressing all of the
deficiencies identified in the letter; withdraw the application; or request an opportunity for a hearing.  Even if additional information outlined in a CRL is
submitted, the FDA may ultimately decide that the BLA does not satisfy the criteria for approval.

The  receipt  of  regulatory  approval  often  takes  many  years,  involving  the  expenditure  of  substantial  financial  resources.  The  speed  with  which
approval is granted often depends on a number of factors, including the severity of the disease in question, the availability of alternative treatments and the
risks and benefits demonstrated in clinical trials. The FDA may also impose conditions upon approval. For example, it may require a Risk Evaluation and
Mitigation Strategy, or REMS, for a product. This can include various required elements, such as publication of a medication guide, patient package insert,
a  communication  plan  to  educate  health  care  providers  of  the  drug’s  risks  and/or  restrictions  on  distribution  and  use,  such  as  limitations  on  who  may
prescribe or dispense the drug. Following product approval, a REMS may also be required by the FDA if new safety information is discovered and the
FDA determines that a REMS is necessary to ensure that the benefits of the product outweigh the risks.

The  FDA  may  also  significantly  limit  the  indications  or  populations  approved  for  a  given  product,  require  that  contraindications,  warnings,  or
precautions  be  included  in  the  product  labeling,  including  a  boxed  warning,    and/or  require,  as  a  condition  of  approval,  enhanced  labeling,  special
packaging or labeling, post-approval clinical trials, distribution or other risk management mechanisms, expedited reporting of certain adverse events, pre-
approval  of  promotional  materials  or  restrictions  on  direct-to-consumer  advertising,  any  of  which  could  negatively  impact  the  commercial  success  of  a
drug. The FDA may also not approve label statements that are necessary for successful commercialization and marketing.

14

 
After approval, some types of changes to the approved product, such as adding new indications, manufacturing changes, and additional labeling
claims, are subject to further testing requirements and FDA review and approval. The FDA may also withdraw the product approval if compliance with the
pre- and post-marketing regulatory standards are not maintained or if problems occur after the product reaches the marketplace. Further, should new safety
information arise, additional testing, product labeling, or FDA notification may be required.

Breakthrough  Therapy.  Under  the  provisions  of  the  Food  and  Drug  Administration  Safety  and  Innovation  Act,  or  FDASIA,  the  FDA  may
designate a product as a breakthrough therapy if the product is intended, alone or in combination with one or more other products, to treat a serious or life-
threatening  disease  or  condition,  and  preliminary  clinical  evidence  indicates  that  the  product  may  demonstrate  substantial  improvement  over  existing
therapies on one or more clinically significant endpoints, such as substantial treatment effects observed early in clinical development. Products designated
as breakthrough therapies are also eligible for accelerated approval. The FDA must take certain actions, such as holding timely meetings and providing
advice, intended to expedite the development and review of an application for approval of a breakthrough therapy.

Orphan Drugs. Under the Orphan Drug Act, an applicant can request the FDA to designate a product as an “orphan drug” in the United States if
the drug is intended to treat an orphan, or rare, disease or condition. A disease or condition is considered orphan if it affects fewer than 200,000 people in
the United States, or affecting more than 200,000 in the United States and for which there is no reasonable expectation that the cost of developing and
making the product available in the United States will be recovered from United States sales. Additionally, sponsors must present a plausible hypothesis for
clinical superiority to obtain orphan drug designation if there is a product already approved by the FDA that that is considered by the FDA to be the same
as the already approved product and is intended for the same indication. This hypothesis must be demonstrated to obtain orphan exclusivity. Orphan drug
designation  must  be  requested  before  submitting  a  BLA.  Products  designated  as  orphan  drugs  are  eligible  for  special  grant  funding  for  research  and
development, potential tax credits for research, waived user fees for marketing applications and a seven-year period of market exclusivity after marketing
approval. The tax advantages, however, were limited in the 2017 Tax Cuts and Jobs Act.

Orphan drug exclusivity (afforded to the first applicant to receive approval for an orphan designated drug) prevents FDA approval of applications
by others for the same drug for the designated orphan disease or condition. The FDA may approve a subsequent application from another applicant if the
FDA determines that the application is for a different drug or different use, or if the FDA determines that the subsequent product is clinically superior, or
that the holder of the initial orphan drug approval cannot assure the availability of sufficient quantities of the drug to meet the public’s need. A grant of an
orphan designation is not a guarantee that a product will be approved. On November 26, 2019 FDA granted Orphan Drug Designation to APVO436, a
bispecific antibody candidate intended for the treatment of acute myelogenous leukemia (AML). APVO436 is currently being evaluated in a Phase 1/1b
clinical trial in patients with AML and myelodysplastic syndrome (MDS).

Post-Approval Requirements. Any biologic for which we receive FDA approval will be subject to continuing regulation by the FDA, including,
among other things, record keeping requirements, reporting of adverse experiences, reporting of deviations and shortages, providing the FDA with updated
safety  and  efficacy  information,  product  sampling  and  distribution  requirements,  current  good  manufacturing  practices,  or  cGMP,  and  restrictions  on
advertising  and  promotion.  Adverse  events  that  are  reported  after  marketing  approval  can  result  in  additional  limitations  being  placed  on  the  product’s
distribution  or  use  and,  potentially,  withdrawal  or  suspension  of  the  product  from  the  market.  In  addition,  the  FDA  authority  to  require  post-approval
clinical trials and/or safety labeling changes if warranted. In certain circumstances, the FDA may impose a REMS after a product has been approved.

Facilities involved in the manufacture and distribution of approved products are required to register their establishments with the FDA and certain
state agencies, list their manufactured products, and are subject to periodic unannounced inspections by the FDA for compliance with cGMP and other
laws. Recently, the information that must be submitted to FDA regarding manufactured products was expanded through the Coronavirus Aid, Relief, and
Economic Security, or CARES, Act to include the volume of drugs produced during the prior year.  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,
require  label  modifications,  or  request  product  recalls,  among  other  actions,  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

 
The FDA also closely monitors advertising and promotional materials we may disseminate for our products for compliance with restrictions on off-
label  promotion  and  other  laws.  We  may  not  promote  our  products  for  conditions  of  use  that  are  not  included  in  the  approved  package  inserts  for  our
products. Physicians, in their independent professional medical judgment, however, may prescribe legally available products for unapproved indications
that are not described in the product’s labeling and that differ from those tested and approved by the FDA. Certain additional restrictions on advertising and
promotion  exist  for  products  that  have  boxed  warnings  in  their  approved  package  inserts.    The  FDA  and  other  agencies  actively  enforce  the  laws  and
regulations  prohibiting  the  promotion  of  off-label  uses,  and  a  company  that  is  found  to  have  improperly  promoted  off-label  uses  may  be  subject  to
significant liability, including, but not limited to, criminal and civil penalties under the FDCA and False Claims Act, exclusion from participation in federal
healthcare programs, mandatory compliance programs under corporate integrity agreements, suspension and debarment from government contracts, and
refusal of orders under existing government contracts.

Biosimilars and Exclusivity. The Biologics Price Competition and Innovation Act of 2009, or BPCIA, creates an abbreviated approval pathway for
biological  products  shown  to  be  highly  similar  to  or  interchangeable  with  an  FDA-licensed  reference  biological  product.  Biosimilarity  sufficient  to
reference  a  prior  FDA-approved  product  requires  a  high  similarity  to  the  reference  product  notwithstanding  minor  differences  in  clinically  inactive
components,  and  no  clinically  meaningful  differences  between  the  biological  product  and  the  reference  product  in  terms  of  safety,  purity,  and  potency.
Biosimilarity  must  be  shown  through  analytical  studies,  animal  studies,  and  at  least  one  clinical  trial,  absent  a  waiver  by  the  FDA.  There  must  be  no
difference between the reference product and a biosimilar in mechanism of action, conditions of use, route of administration, dosage form, and strength. A
biosimilar product may be deemed interchangeable with a prior approved product if it meets the higher hurdle of demonstrating that it can be expected to
produce the same clinical results as the reference product and, for products administered multiple times, the biologic and the reference biologic may be
switched after one has been previously administered without increasing safety risks or risks of diminished efficacy relative to exclusive use of the reference
biologic.

A reference biologic is granted 12 years of exclusivity from the time of first licensure, and no application for a biosimilar can be submitted for four
years from the date of licensure. However, certain changes and supplements to an approved BLA, and subsequent applications filed by the same sponsor,
manufacturer,  licensor,  predecessor  in  interest,  or  other  related  entity  do  not  qualify  for  the  twelve-year  exclusivity  period.  The  PHSA  also  includes
provisions to protect reference products that have patent protection. The biosimilar product sponsor and reference product sponsor may exchange certain
patent  and  product  information  for  the  purpose  of  determining  whether  there  should  be  a  legal  patent  challenge.  Based  on  the  outcome  of  negotiations
surrounding  the  exchanged  information,  the  reference  product  sponsor  may  bring  a  patent  infringement  suit  and  injunction  proceedings  against  the
biosimilar product sponsor. The biosimilar applicant may also be able to bring an action for declaratory judgment concerning the patent.

In an effort to increase competition in the biologic product marketplace, Congress, the executive branch, and FDA have taken certain legislative
and  regulatory  steps.  For  example,  in  2020,  FDA  finalized  a  guidance  to  facilitate  drug  and  biologic  product  importation.  Moreover,  the  2020  Further
Consolidated  Appropriations  Act  included  provisions  requiring  that  sponsors  of  approved  biologic  products,  including  those  subject  to  REMS,  provide
samples  of  the  approved  products  to  persons  developing  biosimilar  products  within  specified  timeframes,  in  sufficient  quantities,  and  on  commercially
reasonable market-based terms. Failure to do so can subject the approved product sponsor to civil actions, penalties, and responsibility for attorney’s fees
and costs of the civil action. This same bill also includes provisions with respect to shared and separate REMS programs for reference and generic drug
products.

Patent Term Restoration.  If approved, biologic products may also be eligible for periods of U.S. patent term restoration. If granted, patent term
restoration extends the patent life of a single unexpired patent, that has not previously been extended, for a maximum of five years. The total patent life of
the  product  with  the  extension  also  cannot  exceed  fourteen  years  from  the  product’  approval  date.  Subject  to  the  prior  limitations,  the  period  of  the
extension is calculated by adding half of the time from the effective date of an IND to the initial submission of a marketing application, and all of the time
between the submission of the marketing application and its approval. This period may also be reduced by any time that the applicant did not act with due
diligence.

16

 
 
Regulation in the European Union. Product development, the regulatory approval process and safety monitoring of medicinal products and their
manufacturers in the European Union proceed broadly in the same way as they do in the United States. Therefore, many of the issues discussed above
apply similarly in the context of the European Union. In addition, drugs are subject to the extensive price and reimbursement regulations of the various EU
member states. The Clinical Trials Directive 2001/20/EC, as amended (“CTD”) (and to be replaced by the Clinical Trial Regulation EU 536/2014) (“CTR”)
(it  is  anticipated  by  December  2021),  provides  a  system  for  the  approval  of  clinical  trials  in  the  European  Union  via  (in  the  case  of  the  CTD)
implementation  through  national  legislation  of  the  member  states.  The  CTR  is  directly  applicable  in  all  member  states  without  the  need  for  national
implementation. Under this system, approval (a CTA) must be obtained from the competent national authority of an EU member state in which the clinical
trial is to be conducted. Once the CTR comes into effect however, it will be possible within the EU to make a single harmonized electronic submission and
have  a  single  assessment  process  for  clinical  trials  conducted  in  multiple  member  states.  CTA  applications  must  be  supported  by  an  investigational
medicinal product dossier with supporting information prescribed by the CTD and corresponding national laws of the member states and further detailed in
applicable  guidance  documents.  Furthermore,  a  clinical  trial  may  only  be  started  after  a  competent  ethics  committee  has  issued  a  favorable  opinion  in
response to a request for an opinion to the Ethics Committee.

Healthcare Fraud and Abuse and Anti-Corruption Laws

Various federal and state laws pertaining to health care “fraud and abuse” exist, including state and federal anti-kickback laws false claims laws,
and patent privacy and security laws. Anti-kickback laws make it illegal for a drug manufacturer to knowingly and willfully solicit, offer, receive or pay
any remuneration in exchange for, to induce, or in return for, the referral of business that may be reimbursed by a third party payor (including Medicare and
Medicaid), including the purchase, prescribing or recommendation of a particular drug. Due to the breadth of the statutory provisions, it is possible that our
practices might be challenged under anti-kickback or similar laws. Civil and criminal false claims laws, false statement laws and civil monetary penalty
laws prohibit, among other things, anyone from knowingly presenting, or causing to be presented for payment, to third-party payors (including Medicare
and  Medicaid)  claims  for  reimbursed  drugs  or  services  that  are  false  or  fraudulent,  claims  for  items  or  services  not  provided  as  claimed  or  claims  for
medically  unnecessary  items  or  services.  Our  activities  relating  to  the  sale  and  marketing  of  our  products  may  be  subject  to  scrutiny  under  these  laws.
Privacy and security laws, such as the Health Insurance Portability and Accountability Act of 1996, or HIPAA, create federal criminal and civil liability for
executing a scheme to defraud any healthcare benefit program or knowingly and willfully falsifying, concealing or covering up a material fact or making
any materially false statement in connection with the delivery of or payment for healthcare benefits, items or services. Additionally, HIPAA, as amended by
the  Health  Information  Technology  for  Economic  and  Clinical  Health,  or  HITECH,  and  their  respective  implementing  regulations,  impose  certain
requirements relating to the privacy, security, and transmission of individually identifiable health information.

In  addition,  as  part  of  the  Affordable  Care  Act,  the  federal  government  enacted  the  Physician  Payment  Sunshine  Act.  Manufacturers  of  drugs
biologics  and  devices  that  are  reimbursed  by  Medicare,  Medicaid  or  the  Children’s  Health  Insurance  Program  are  required  to  annually  report  to  CMS
payments  and  transfers  of  value  made  to  physicians  and  teaching  hospitals,  and  ownership  or  investment  interest  held  by  physicians  and  their  family
members.

Our operations are also subject to compliance with the U.S. Foreign Corrupt Practices Act, or FCPA, which prohibits corporations and individuals
from directly or indirectly paying, offering to pay, or authorizing the payment of anything of value to any foreign government official or employee, or any
foreign political party or political candidate in an attempt to obtain or retain business or to otherwise influence such official, employee, party or candidate
in his or her or its official capacity. Our operations are also subject to compliance with the U.K. Bribery Act of 2010, which applies to activities both in the
public and private sector, Canada’s Corruption of Foreign Public Officials Act and similar laws and industry codes in other countries where we do business.

Other Regulation

Our  present  and  future  business  has  been  and  will  continue  to  be  subject  to  various  other  laws  and  regulations.  Various  laws,  regulations  and
recommendations relating to safe working conditions, laboratory practices, the experimental use of animals, and the purchase, storage, movement, import,
export,  use  and  disposal  of  hazardous  or  potentially  hazardous  substances,  including  radioactive  compounds  and  infectious  disease  agents  used  in
connection with our product development, are or may be applicable to our activities.

ORGANIZATIONAL HISTORY

Aptevo  was  formed  as  a  wholly-owned  subsidiary  of  Emergent  for  the  purpose  of  serving  as  the  parent  company  for  the  development-based
biotechnology  business  focused  on  novel  oncology,  hematology,  and  autoimmune  and  inflammatory  therapeutics  and  was  incorporated  in  Delaware  in
February  2016.  On  August  1,  2016,  Emergent  effectuated  a  spin-off  of  Aptevo  into  an  independent  publicly  traded  company  and  made  a  pro  rata
distribution  of  Aptevo  common  stock  to  Emergent’s  stockholder  base  at  that  time.  Accordingly,  Aptevo  has  operated  as  an  independent  publicly  traded
company since August 1, 2016.

Item 1A. Risk Factors.

We  are  subject  to  significant  risks  and  uncertainties  that  could  impact  the  Company’s  businesses,  results  of  operations  and  financial  condition,
including by causing our actual results to differ materially from those projected in any forward-looking statements. Additional risks and uncertainties that
are not currently known to the Company or management or that are not currently believed by the Company or management to be material may also harm
the Company’s business, financial condition and results of operation. You should carefully consider the following risks and other information in this Annual
Report on Form 10-K in evaluating us and our common stock.

RISK FACTOR SUMMARY

The following is a summary of the material risks to our business, operations, and ownership of our common stock:
•
•
•

We have a history of losses and may not be profitable in the future.
We will require additional capital and may be unable to raise capital when needed or on acceptable terms.
Our  future  income  will  depend,  in  part,  on  the  ability  of  Medexus  to  successfully  further  develop,  market  and  commercialize  IXINITY,
resulting in milestone payments and deferred payments to the Company by Medexus.
Our future income will depend, in part, on the ability of Pfizer to successfully sell RUXIENCE and our receipt of milestone and royalty
payments from HCR in connection therewith. If Pfizer is unable, or does not devote sufficient resources, to maintain or continue increasing
sales  of  RUXIENCE,  or  if  HCR  does  not  comply  with  the  Royalty  Purchase  Agreement,  our  results  of  operations  will  be  adversely
affected.
COVID-19 could adversely impact our business, including our clinical trials.
The terms of our credit agreement may restrict the operation of our business and limit the cash available for investment in our business
operations.
If we experience delays or difficulties in the enrollment of patients in clinical trials, the time to reach critical trial data and receipt of any
necessary regulatory approvals could be delayed.
Our  ability  to  grow  revenues  and  execute  on  our  long-term  strategy  depends  heavily  on  our  ability  to  discover,  develop,  and  obtain
marketing approval for our product candidates.
We may not be successful in our efforts to use and further develop our ADAPTIR or ADAPTIR-FLEX platforms.
Our  long-term  success  depends,  in  part,  upon  our  ability  to  develop,  receive  regulatory  approval  for  and  commercialize  our  product
candidates.
If we are unable to protect our intellectual proprietary rights, our business could be harmed.
Our stock price may be volatile.
We may be subject to periodic litigation, which could result in losses or unexpected expenditure of time and resources.
Actions of an activist stockholder against us have been disruptive and costly and the notice the activist stockholder has sent indicating he
will wage a proxy contest and seek representation on our Board could cause uncertainty about the strategic direction of our business.

volatility in the trading price of our common stock and interfere with our efforts to raise capital.

RISKS RELATED TO OUR BUSINESS

Financial Risks

We have a history of losses and may not be profitable in the future.

We have experienced significant operating losses and we may not achieve profitability in the future. For the year ended December 31, 2020 and
2019, we had net losses of $17.8 million and $40.4 million, respectively. As of December 31, 2020, we had an accumulated deficit of $185.6 million. We
expect  to  continue  to  incur  annual  net  operating  losses,  and  will  require  substantial  resources  over  the  next  several  years  as  we  expand  our  efforts  to
discover, develop and commercialize immunotherapeutic candidates, for the foreseeable future. While we believe our existing cash and cash equivalents
and  the  funding  provided  by  our  IXINITY  deferred  payment  streams,  the  Royalty  Purchase  Agreement  with  HCR,  credit  agreement,  our  Equity
Distribution Agreement with Piper Sandler & Co (Piper Sandler) entered into in December 2020 (the Equity Distribution Agreement) and our Purchase
Agreement with Lincoln Park Capital Fund, LLC (Lincoln Park), entered into in December 2018 (the Purchase Agreement), and exercises of warrants will
provide us with sufficient liquidity to meet our cash requirements through 2021, our future success and ability to attain profitability will depend upon our
ability to develop and take to market our product candidates.

We will require additional capital and may be unable to raise capital when needed or on acceptable terms.

As of December 31, 2020, we had cash, cash equivalents, and restricted cash in the amount of $42.5 million. We will require additional funding to
grow our business including to develop additional products, support commercial marketing activities, or otherwise provide additional financial flexibility.
In October 2019, we implemented an expense reduction plan that reduced annual expenditures by approximately 30%, including streamlining research and
development  programs,  through  reducing  investment  in  certain  programs;  cut-backs  in  legal,  professional  and  consulting  expenses;  reduction  of  leased
space, cut-backs in non-commercial headcount; and reductions in executive and board cash compensation, with such compensation restored to previous
levels in August 2020. If we are not able to secure adequate additional funding, we may need to make further reductions in spending. This may include
extending payment terms with suppliers, liquidating assets, and suspending or curtailing planned programs. We may also have to further delay, reduce the
scope of, suspend or eliminate one or more research and development programs. A failure to raise the additional funding or to effectively implement cost
reductions could harm our business, results of operations and future prospects. Our future capital requirements will depend on many factors, including:

•

•

•

•

•

•

•

•

•

the resolution of actions of activist investors;

the  level,  timing  and  receipt  of  any  milestone  or  deferred  payments  under  our  agreement  with  Medexus  with  respect  to  the  sales  of
IXINITY;

whether and to what extent future proceeds are received under our royalty purchase agreement with HCR;

the extent to which we invest in products or technologies;

the ability to satisfy the payment obligations and covenants under any future indebtedness;

the ability to secure partnerships and/or collaborations that generate additional cash;

capital improvements to our facilities;

the scope, progress, results, and costs of our development activities; and,

future clinical development costs and requirements to complete dosing of Phase 1/1b clinical trial for APVO436, as well as future clinical
trials.

20

 
 
 
 
 
 
 
 
 
 
 
If our capital resources are insufficient to meet our future capital requirements, we will need to finance our cash needs through bank loans, public
or private equity or debt offerings, collaboration and licensing arrangements, or other strategic transactions. Future issuances of common stock may include
(i) any sale of up to the remaining $50.0 million worth of shares of our common stock pursuant to our Equity Distribution Agreement with Piper Sandler &
Co  entered  into  in  December  2020,  (ii)  any  sale  of  up  to  $35.0  million  worth  of  shares  of  our  common  stock  in  a  private  placement  pursuant  to  our
Purchase  Agreement  with  Lincoln  Park  Capital  Fund,  LLC,  or  Lincoln  Park,  entered  into  in  December  2018,  and  (iii)  the  issuance  of  up  to  404,694
remaining outstanding shares of common stock upon the exercise of warrants issued in connection with our March 2019 public offering of common stock
and warrants. Public or bank debt financing, if available, may involve agreements that include covenants limiting or restricting our ability to take specific
actions,  such  as  incurring  additional  debt,  making  capital  expenditures,  pursuing  acquisition  opportunities,  or  declaring  dividends.  If  we  raise  funds  by
issuing equity securities, our stockholders will experience dilution. If we raise funds through collaboration and licensing arrangements with third parties or
enter into other strategic transactions, it may be necessary to relinquish valuable rights to our technologies or product candidates or grant licenses on terms
that may not be favorable to us.

Current economic conditions, including the impact of COVID-19 on our operations or on the global economy and capital markets, may make it
difficult to obtain additional financing on attractive terms, or at all. If financing is unavailable or lost, our business, results of operations, financial condition
and financial prospects would be adversely affected and we could be forced to delay, reduce the scope of or eliminate many of our planned activities.

Actions of an activist stockholder against us have been disruptive and costly and the notice the activist stockholder has sent indicating he will wage a
proxy contest and seek representation on our Board could cause uncertainty about the strategic direction of our business.

On  November  6,  2020,  Tang  filed  a  statement  on  Schedule  13D  to  report  that  Tang  had  purchased  1,760,000  shares  of  our  common  stock,
representing  at  the  time  approximately  54%  of  our  issued  and  outstanding  shares  of  Common  Stock  (the  Tang  Ownership  Change),  although  Tang  has
subsequently been diluted to a 39.6% beneficial ownership position, primarily through the exercise of certain warrants that were issued and outstanding
prior to Tang acquiring its ownership position in Aptevo.  

On  November  18,  2020,  our  Board  received  a  written  unsolicited,  non-binding  indication  of  interest  from  Tang,  proposing  to  acquire  all  of  the
outstanding  shares  of  our  common  stock  not  already  beneficially  owned  by  Tang  for  $50.00  per  share  in  cash,  subject  to  confirmatory  due  diligence
conducted under a customary non-disclosure agreement. We have had a series of communications with Tang during which we attempted to negotiate a non-
disclosure agreement to permit discussions covering our nonpublic information and our operations.

The Aptevo Board was open to exploring the indication of interest from Tang and made earnest efforts to evaluate it. However, it was unable to do
so  because  it  was  unable  to  reach  agreement  with  Tang  on  the  terms  of  a  customary  non-disclosure  agreement,  including  limitations  on  the  use  of
confidential  information  by  Tang.    Had  agreement  on  the  terms  of  a  non-disclosure  agreement  been  reached,  it  would  have  permitted  the  exchange  of
confidential information and would have enabled both parties to conduct due diligence.  In this early stage of the Company’s development, the Aptevo
Board  believes  it  is  difficult  for  the  market  to  accurately  value  the  potential  of  Aptevo’s  proprietary  platform  technologies  and  therapeutic  candidates,
which  have  just  begun  to  demonstrate  their  effectiveness  and  potentially  life-saving  capabilities  to  the  Company’s  patients,  shareholders  and  other
stakeholders. The Board will continue to carefully evaluate any indications of interest and proposals for strategic transactions that it receives from current
shareholders or otherwise, in line with its fiduciary duties and commitment to acting in the best interests of all of the Company’s shareholders.

On February 9, 2021, Tang announced its intention to nominate two candidates for election to our board of directors at our 2021 annual meeting of
stockholders and submitted an advisory stockholder proposal for consideration at our 2021 annual meeting of stockholders to commence a process to sell
Aptevo to the highest bidder. We have incurred and may continue to incur additional expenses by retaining the services of various professionals to advise
us on responding to these matters.

21

 
 
The Board and management team strive to maintain constructive communications with our stockholders, including Tang, and welcomes their views
and opinions with the goal of enhancing value for all stockholders. However, an activist campaign that seeks to replace members of our Board or changes
in our strategic direction could have an adverse effect on us because:

•

•

•

•

•

•

Responding to actions by Tang and other activist stockholders can disrupt our operations, are costly and time-consuming, and divert the
attention  of  our  Board  and  senior  management  team  from  the  pursuit  of  business  strategies,  which  could  adversely  affect  our  results  of
operations and financial condition;

Perceived uncertainties as to our future direction as a result of changes to the composition of our Board or changes to our stockholder base
may lead to the perception of a change in the direction of the business, instability or lack of continuity which may be exploited by our
competitors, may result in the loss of potential business opportunities, cause concern for those enrolling in our clinical trial, and make it
more difficult to attract and retain qualified personnel and business partners;

The Initial Proposal has interfered, and may continue to interfere, with our efforts to raise capital;

These  and  similar  types  of  actions  could  cause  significant  fluctuations  in  our  stock  price  based  on  temporary  or  speculative  market
perceptions or other factors that do not necessarily reflect the underlying fundamentals and prospects of our business;

As a result of the pending proxy contest, or if other activist stockholder activities ensue, our business could be adversely affected because
responding to proxy contests can be disruptive, costly, and time-consuming; and,

If  individuals  are  elected  to  our  Board  with  a  specific  agenda,  it  may  adversely  affect  our  ability  to  effectively  implement  our  business
strategy and to create additional value for our stockholders.

The Initial Proposal, the Tang Stockholder Proposals and similar proposals from other third-parties, and our responses thereto, may cause volatility in
the trading price of our common stock and interfere with our efforts to raise capital.

We have retained Piper Sandler to assist and advise the Board in its evaluation of the Initial Proposal, as well as our other strategic alternatives,
including remaining independent and executing our existing strategic plans. The Board has met on a number of occasions to carefully evaluate and consider
the Initial Proposal and representatives of the Company have discussed the Initial Proposal directly with representatives of Tang.

The Aptevo Board was open to exploring the indication of interest from Tang and made earnest efforts to evaluate it. However, it was unable to do
so  because  it  was  unable  to  reach  agreement  with  Tang  on  the  terms  of  a  customary  non-disclosure  agreement,  including  limitations  on  the  use  of
confidential  information  by  Tang.    Had  agreement  on  the  terms  of  a  non-disclosure  agreement  been  reached,  it  would  have  permitted  the  exchange  of
confidential information and would have enabled both parties to conduct due diligence.  In this early stage of the Company’s development, the Aptevo
Board  believes  it  is  difficult  for  the  market  to  accurately  value  the  potential  of  Aptevo’s  proprietary  platform  technologies  and  therapeutic  candidates,
which  have  just  begun  to  demonstrate  their  effectiveness  and  potentially  life-saving  capabilities  to  the  Company’s  patients,  shareholders  and  other
stakeholders. The Board will continue to carefully evaluate any indications of interest and proposals for strategic transactions that it receives from current
shareholders or otherwise, in line with its fiduciary duties and commitment to acting in the best interests of all of the Company’s shareholders.

As a result of the uncertainty surrounding the Tang Stockholder Proposals, our response to the Initial Proposal, and similar proposals from other

third-parties, the future trading price of our common stock is likely to be volatile and could be subject to wide price fluctuations.

Our operating results are unpredictable and may fluctuate.

Our operating results are difficult to predict and will likely fluctuate from quarter to quarter and year to year, due to a variety of factors, including:

•
•

the resolution of the Tang Stockholder Proposals;
the level and timing of any milestone or deferred payments with respect to sales of IXINITY by Medexus;

22

 
 
 
 
 
 
 
 
 
•
•

•

whether and to what extent future proceeds are received under our royalty purchase agreement with HCR;
the extent of any payments received from collaboration arrangements and development funding as well as the achievement of development
and clinical milestones under collaboration and license agreements that we may enter into from time to time and that may vary significantly
from quarter to quarter; and,
the timing, cost, and level of investment in our research and development activities as well as expenditures we will or may incur to acquire
or develop additional technologies, products and product candidates.

Due to COVID-19, we may experience delays in opportunities to partner our product candidates, due to financial and other impacts on potential
partners. Additionally, we may experience potential impacts on our future milestone or deferred payments from Medexus, which may impact Medexus’
ability to continue to successfully commercialize the IXINITY businesses, respectively. In 2020, we did see an impact of COVID-19 on our business as
some  of  our  clinical  sites  were  at  reduced  capacity  or  closed,  as  well  as  our  participation  in  the  BEAT  AML  trial  being  delayed  by  the  Leukemia  and
Lymphoma Society. These and other factors may have a material adverse effect on our business, results of operations and financial condition.

Our  future  income  will  depend,  in  part,  on  the  ability  of  Medexus  to  successfully  further  develop,  market  and  commercialize  IXINITY,  resulting  in
milestone payments and deferred payments to the Company by Medexus.

On February 28, 2020, we entered into an LLC Purchase Agreement with Medexus, pursuant to which we sold all of the issued and outstanding
limited liability company interests of Aptevo BioTherapeutics, a subsidiary of Aptevo that wholly owns the IXINITY and related Hemophilia B business.
We are entitled to receive future potential payments to the extent of the achievement of certain regulatory and commercial milestones and through deferred
payments  based  on  net  sales  of  IXINITY.  Royalties  are  earned  at  the  rate  of  2%  of  net  revenue  through  the  earlier  of  June  2022  or  completion  of  the
IXINITY pediatric trial being run by Medexus.  After that, the royalty rate will increase to 5%. We no longer control the development, marketing, and
commercialization of IXINITY and are dependent on Medexus to successfully do so.  Although Medexus has agreed to use commercially reasonable efforts
to  commercialize  IXINITY  in  the  ordinary  course  of  business  in  good  faith,  Medexus  may  not  commit  adequate  resources  to  the  further  development,
marketing,  and  commercialization  of  IXINITY,  may  experience  financial  difficulties,  may  face  competition,  or  may  prioritize  other  products  or
initiatives.    Due  to  the  effect  of  the  COVID-19  pandemic  on  the  current  and  future  environment  for  clinical  development  and  regulatory  approval,
Medexus’ ability to continue to successfully commercialize the IXINITY business may be effected, and we may experience potential impacts on our future
deferred  payments  from  Medexus.  The  failure  of  Medexus  to  successfully  market  and  commercialize  IXINITY,  including  because  of  factors  outside  of
Medexus’  control,  could  result  in  lower  than  expected  milestone  or  deferred  payments  to  us  and  negatively  impact  our  future  financial  and  operating
results.

Our future income will depend, in part, on the ability of Pfizer to successfully sell RUXIENCE and our receipt of milestone and royalty payments from
HCR in connection therewith. If Pfizer is unable, or does not devote sufficient resources, to maintain or continue increasing sales of RUXIENCE, or if
HCR does not comply with the Royalty Purchase Agreement, our results of operations will be adversely affected.

On June 25, 2020, we announced that we will receive royalty payments from Pfizer related to sales of a rituximab biosimilar product, RUXIENCE
(Rituximab-pvvr), which was approved by the U.S. Food and Drug Administration in July 2019 and launched by Pfizer in the United States and Japan in
early 2020, and the European Union in the third quarter of 2020. The payments from Pfizer relate to a collaboration and license agreement acquired by us
as part of our spin-off from Emergent in 2016, which applies a fixed royalty rate of 2.5% on global net sales. The agreement was originally executed by
Trubion Pharmaceuticals (which was subsequently acquired by Emergent) and Wyeth (a wholly-owned subsidiary of Pfizer). The royalty term runs until
the seventh anniversary of the first commercial sale of the biosimilar. Royalty payments to us are due within 60 days after the end of each quarter. Although
the agreement was terminated in 2012, the royalty obligation thereunder survived.

On March 30, 2021, we entered into and closed a Royalty Purchase Agreement with HCR (Royalty Purchase Agreement) pursuant to which we
sold  to  HCR  the  right  to  receive  all  royalty  payments  made  by  Pfizer  in  respect  of  net  sales  of  RUXIENCE.  Under  the  terms  of  the  Royalty  Purchase
Agreement, we received $35 million (the Investment Amount) at closing and we are eligible to receive additional payments in aggregate of up to an  $32.5
million based on the achievement of sales milestones in 2021, 2022, and 2023 (collectively, the Milestone Amounts). The Royalty Purchase Agreement
further provides that, once HCR reaches aggregate royalty payments totaling 190% of the Investment Amount plus the Milestone Amounts to the extent
paid to us by HCR, we will be entitled to receive 50% of any additional royalty payments by Pfizer thereafter.

23

 
 
 
 
We  have  no  control  over  the  sales  of  RUXIENCE  and  are  therefore  dependent  on  the  efforts  and  ability  of  Pfizer  to  generate  net  sales  of
RUXIENCE sufficient for us to receive Milestone Payments and additional royalty payments under the Royalty Purchase Agreement.  The failure of Pfizer
to successfully generate such net sales could negatively impact our future financial and operating results and our results of operations could therefore be
adversely affected. Additionally, even if Pfizer is able to generate net sales of RUXIENCE sufficient for us to receive such payments, if HCR breaches the
Royalty  Purchase  Agreement  (for  example,  by  not  making  required  payments  when  due,  or  at  all),  disputes  or  litigation  may  arise.  Such  disputes  or
litigation could be time-consuming and expensive and could adversely affect our business.

We  face  product  liability  exposure,  which  could  cause  us  to  incur  substantial  liabilities  and  negatively  affect  our  business,  financial  condition,  and
results of operations.

The nature of our business exposes us to potential liability inherent in pharmaceutical products, including with respect to the testing of our product
candidates in clinical trials and any product candidates that we successfully develop. Product liability claims might be made by patients in clinical trials,
consumers, health care providers or pharmaceutical companies or others that sell any products that we successfully develop. These claims may be made
even  with  respect  to  those  products  that  are  manufactured  in  licensed  and  regulated  facilities  or  otherwise  receive  regulatory  approval  for  study  or
commercial sale. We cannot predict the frequency, outcome, or cost to defend any such claims.

If we cannot successfully defend ourselves against future claims that our product candidates caused injuries, we may incur substantial liabilities.

Regardless of merit or eventual outcome, product liability claims may result in:

•

•

•

•

•

•

•

adverse publicity and/or injury to our reputation;

withdrawal of clinical trial participants;

costs to defend the related litigation;

substantial monetary awards to trial participants or patients;

decreased demand or withdrawal of an approved product;

loss of revenue; and,

an inability to commercialize products that we may develop.

The amount of insurance that we currently hold may not be adequate to cover all liabilities that may occur. Further product liability insurance may
be difficult and expensive to obtain. We may not be able to maintain insurance coverage at a reasonable cost and we may not be able to obtain insurance
coverage that will be adequate to satisfy all potential liabilities. Claims or losses in excess of our product liability insurance coverage could have a material
adverse effect on our business, financial condition, and results of operations. The cost of defending any product liability litigation or other proceeding, even
if resolved in our favor, could be substantial. Uncertainties resulting from the initiation and continuation of product liability litigation or other proceedings
could have a material adverse effect on our ability to compete in the marketplace. Product liability claims, regardless of merit or eventual outcome, may
absorb  significant  management  time  and  result  in  reputational  harm,  potential  loss  of  revenue  from  decreased  demand  for  any  product  candidates  we
successfully develop, withdrawal of clinical trial participants and potential termination of clinical trial sites or entire clinical programs, and could cause our
stock price to fall.

Our success is dependent on our continued ability to attract, motivate and retain key personnel, and any failure to attract or retain key personnel may
negatively affect our business.

Because of the specialized scientific nature of our business, our ability to develop products and to compete with our current and future competitors
largely depends upon our ability to attract, retain, and motivate highly qualified managerial and key scientific and technical personnel. If we are unable to
retain  the  services  of  one  or  more  of  the  principal  members  of  senior  management,  including  our  Chief  Executive  Officer,  Marvin  L.  White,  our  Chief
Financial  Officer,  Jeffrey  G.  Lamothe,  our  Chief  Scientific  Officer,  Jane  Gross  Ph.D.,  or  other  key  employees,  our  ability  to  implement  our  business
strategy  could  be  materially  harmed.  We  face  intense  competition  for  qualified  employees  from  biotechnology  and  pharmaceutical  companies,  research
organizations and academic institutions. Attracting, retaining, or replacing these personnel on acceptable terms may be difficult and time-consuming given

24

 
 
 
 
 
 
 
 
the  high  demand  in  our  industry  for  similar  personnel.  We  believe  part  of  being  able  to  attract,  motivate  and  retain  personnel  is  our  ability  to  offer  a
competitive  compensation  package,  including  equity  incentive  awards.  If  we  cannot  offer  a  competitive  compensation  package  or  otherwise  attract  and
retain  the  qualified  personnel  necessary  for  the  continued  development  of  our  business,  we  may  not  be  able  to  maintain  our  operations  or  grow  our
business. Furthermore, we have experienced and may experience an impact on the health of key personnel due to COVID-19.

COVID-19 could adversely impact our business, including our clinical trials.

Since  March  of  2020,  a  novel  strain  of  coronavirus,  COVID-19,  has  spread  through  the  world,  including  the  United  States.  The  COVID-19
outbreak  has  caused  severe  global  economic  and  societal  disruptions  and  uncertainties,  and  we  have  experienced  disruptions  that  have  impacted  our
business and clinical trials, including, limitation of company operations, including implementing work from home policies and office closures; delays or
difficulties in receiving deliveries of critical experimental materials; delays or difficulties in enrolling patients in our clinical trials; delays or difficulties in
clinical site initiation, including difficulties in recruiting clinical site investigators and clinical site staff; diversion of healthcare resources away from the
conduct of clinical trials, including the diversion of hospitals serving as our clinical trial sites and hospital staff supporting the conduct of our clinical trials;
delay  in  participation  of  APVO436  in  the  Beat  AML  trial;  interruption  of  key  clinical  trial  activities,  such  as  patient  enrollment  and  clinical  trial  site
monitoring;  and,  limitations  in  employee  resources  that  would  otherwise  be  focused  on  our  business,  including  the  conduct  of  our  research  and
development activities and process development activities, due to the illness of employees or their families, or the preference of employees to avoid contact
with large groups of people.

We  may  continue  to  experience  disruptions  in  the  future,  or  additional  disruptions  that  could  severely  impact  our  business,  such  as  delays  or
difficulties to the financing environment and raising capital due to economic uncertainty; delays in opportunities to partner our product candidates, due to
financial  and  other  impacts  on  potential  partners;  diversion  of  healthcare  resources  away  from  the  conduct  of  clinical  trials,  including  the  diversion  of
hospitals serving as our clinical trial sites and hospital staff supporting the conduct of our clinical trials; potential impacts on our future deferred payments
and  milestones  from  Medexus  due  to  the  environment  which  may  impact  Medexus’  ability  to  continue  to  successfully  commercialize  the  IXINITY
business; and negative impacts on suppliers and licensees. The global outbreak of COVID-19 continues to rapidly evolve. The COVID-19 pandemic may
also  result  in  the  need  to  suspend  enrollment  into  studies,  patient  withdrawals,  postponement  of  preclinical  studies,  study  modification,  suspension,  or
termination, the introduction of remote study procedures and modified informed consent procedures, study site changes, direct delivery of investigational
products  to  patient  homes  requiring  state  licensing,  study  deviations  or  noncompliance,  and  changes  or  delays  in  site  monitoring.    The  foregoing  may
require that we consult with relevant review and ethics committees and the FDA or comparable foreign regulatory authorities.  The foregoing may also
impact the integrity of our study data. The pandemic could further impact our ability to interact with the FDA or other regulatory authorities, and may
result in delays in the conduct of inspections or review of pending submissions.

The COVID-19 pandemic may further impact our suppliers and manufacturers.  If any of our suppliers or manufacturers are adversely impacted by
the  COVID-19  pandemic  or  the  restrictions  resulting  from  the  outbreak,  if  they  cannot  obtain  the  necessary  supplies,  or  if  such  third  parties  need  to
prioritize other products or customers over us, including under the Defense Production Act, we may experience delays or disruptions in our supply chain,
which could have a material and adverse impact on our business and development plans. Third party manufacturers may also need to implement measures
and  changes,  or  deviate  from  typical  requirements,  because  of  the  COVID-19  pandemic  that  may  otherwise  adversely  impact  our  supply  chains  or  the
quality  of  the  resulting  products  or  supplies.    Depending  on  the  change,  we  may  need  to  obtain  FDA  pre-approval  or  otherwise  provide  FDA  with  a
notification of the change.

The  COVID-19  pandemic  may  result  in  changes  in  laws,  policies,  and  regulations.    By  example,  due  to  the  potential  impact  of  the  COVID-19
outbreak  on  clinical  trials,  drug  development,  and  manufacturing,  FDA  issued  a  number  of  guidances  concerning  how  sponsors  and  investigators  may
address these challenges.  FDA’s guidance is continually evolving.  By further example, in March 2020, the U.S. Congress passed the Coronavirus Aid,
Relief, and Economic Security Act, or CARES Act, which includes various provisions regarding FDA drug shortage reporting requirements, as well as
provisions  regarding  supply  chain  security,  such  as  risk  management  plan  requirements,  and  the  promotion  of  supply  chain  redundancy  and  domestic
manufacturing.  This and any future changes in law may require that we change our internal processes and procedures to ensure continued compliance.

25

 
The extent to which the COVID-19 pandemic may impact our business and clinical trials will depend on future developments, which are highly
uncertain and cannot be predicted with confidence, such as the ultimate geographic spread of the disease, the duration of the outbreak, travel restrictions
and social distancing in the United States and other countries, business closures or business disruptions and the effectiveness of actions taken in the United
States and other countries to contain and treat the disease.

The terms of our credit agreement may restrict the operation of our business and limit the cash available for investment in our business operations.

In  August  2020,  we  entered  into  a  Credit  and  Security  Agreement  (the  Credit  Agreement),  by  and  among  us  and  certain  our  subsidiaries  as
borrowers, MidCap Financial, as agent, and the lenders from time to time party thereto. The terms of the Credit Agreement and borrowings we may make
under the Credit Agreement in the future, could have significant adverse consequences for our business, including:

•

•

•

•

•

requiring us to dedicate a substantial portion of any cash flow from operations to payment on our debt, which would reduce the amounts
available to fund other corporate initiatives;

increasing the amount of interest that we have to pay on borrowings under the Credit Agreement if market rates of interest increase;

requiring  compliance  with  restrictive  covenants  restricting,  among  other  things,  certain  indebtedness,  liens,  dividends  and  other
distributions,  repayment  of  subordinated  indebtedness,  mergers,  dispositions,  investments,  acquisitions,  transactions  with  affiliates  and
modification of organizational documents or certain other agreements, subject to certain exceptions;

requiring compliance with affirmative covenants including payment and reporting covenants; and

placing us at a competitive disadvantage compared to our competitors that have less debt, better debt servicing options or stronger debt
servicing capacity.

We may not have sufficient funds or be able to obtain additional financing to pay the amounts due under the Credit Agreement. In addition, failure
to  comply  with  the  covenants  under  the  Credit  Agreement,  including  those  outside  of  our  control,  such  as  the  appointment  by  Tang  of  a  majority  of
directors to our board, could result in an event of default, notwithstanding the initial waiver and consent obtained upon the Tang Ownership Change. An
event of default could result in the acceleration of amounts due under the Credit Agreement, and we may not be able to obtain additional financing to make
any accelerated payments. Under these circumstances, our lenders could seek to enforce security interests in our assets securing our indebtedness, including
our intellectual property.

We  believe  it  is  likely  that  we  experienced  by  virtue  of  the  Tang  Ownership  Change,  an  “ownership  change”  as  defined  in  Section  382  of  the  U.S.
Internal  Revenue  Code  of  1986,  as  amended  (the  Code),  and,  if  we  are  correct,  the  tax  benefits  of  our  pre-“ownership  change”  net  operating  loss
carryforwards and certain other tax attributes will be subject to annual limitation under Sections 382 and 383 of the Code.  

In  general,  a  corporation  undergoes  an  “ownership  change”  under  Section  382  of  the  Code  if,  among  other  things,  the  stockholders  who  own,
directly or indirectly, 5% or more of the corporation’s stock (by value), or are otherwise treated as “5% shareholders” under Section 382 of the Code and
the  Treasury  regulations  promulgated  thereunder,  increase  their  aggregate  percentage  ownership  (by  value)  of  the  corporation’s  stock  by  more  than  50
percentage points over the lowest percentage of value owned by the 5% shareholders at any time during the applicable testing period, which is generally the
rolling  three-year  period  preceding  the  potential  ownership  change.    Such  potential  ownership  change  testing  events  include  changes  involving  a
shareholder  becoming  a  5%  shareholder  or  arising  from  a  new  issuance  of  capital  stock  or  share  repurchases  by  the  corporation,  subject  to  certain
exceptions.

In  the  event  of  an  “ownership  change,”  Sections  382  and  383  of  the  Code  impose  an  annual  limitation  on  the  amount  of  taxable  income  a
corporation may offset with pre-change net operating loss carryforwards and certain other tax attributes. The annual limitation is generally equal to the
value of the outstanding stock of the corporation immediately before the ownership change (excluding certain capital contributions), multiplied by the long-
term tax-exempt rate as published by the IRS for the month in which the ownership change occurs (the long-term tax-exempt rate for November 2020 is
0.89%).  Any unused annual limitation may generally be carried over to subsequent years until the pre-ownership change net operating loss carryforwards
and certain other tax attributes expire or are fully utilized by the corporation.  Similar provisions of state tax law may also apply to limit the use of state net
operating loss carryforwards and certain other tax attributes.

26

 
 
 
 
 
 
Additionally, Section 382 of the Code includes special rules that apply to a corporation with a significant amount of net unrealized built-in gains or
net  unrealized  built-in  losses  in  its  assets  immediately  prior  to    ownership  change  under  Section  382  of  the  Code.  In  general,  certain  built-in  gains
recognized during the five-year period beginning on the date of the ownership change increases the corporation’s annual limitation under Section 382 and
383 of the Code in the taxable year that such built-in gains are recognized or deemed recognized (but only up to the amount of the net unrealized built-in
gain), while certain built-in losses recognized during such five-year period is subject to the annual limitation under Section 382 of the Code (but only up to
the amount of the net unrealized built-in loss). 

As  of  December  31,  2020,  we  had  approximately  $162.5  million  and  $68.1  million  of  federal  and  state  net  operating  loss  carryforwards,
respectively, available to reduce future taxable income that will begin to expire in 2037 for federal purposes. These net operating loss carryforwards could
expire  unused  and  be  unavailable  to  offset  future  income  tax  liabilities.  Under  the  newly  enacted  federal  income  tax,  federal  net  operating  loss
carryforwards incurred in 2018 and in future years may be carried forward indefinitely, but the deductibility of such federal net operating losses is limited.
It is still uncertain if and to what extent various states will conform to the enacted tax law. We are in the process of completing an IRC Section 382/383
study on our federal and state tax attributes  in connection with the acquisition by Tang of 1,760,000 shares of our common stock in order to determine
whether our ability to use our net operating loss carryforwards and certain other tax attributes in existence prior to the Tang Ownership Change will be
subject to an annual limitation under Sections 382 and 383 of the Code as described above.

We cannot predict or control the occurrence or timing of another ownership change under Section 382 of the Code in the future. In addition, it is
possible that any offering of securities by us could result in an ownership change.  If another ownership change were to occur, future limitations could
apply to our net operating losses and certain other tax attributes, which could result in a material amount of our net operating loss carryforwards and certain
other tax attributes becoming unavailable to offset future income tax liabilities.

The realization of all or a portion of our deferred income tax assets (including net operating loss carryforwards) is dependent upon the generation
of future income during the statutory carryforward periods. Our inability to utilize our limited pre-ownership change net operating loss carryforwards and
certain other tax attributes, or the occurrence of a future ownership change and resulting additional limitations to these tax attributes, could have a material
adverse effect on our financial condition, results of operations and cash flows.

Product Development Risks

The results of our current and planned clinical trials may not satisfy the requirements of the FDA or non-U.S. regulatory authorities.  Interim or top
line data may be subject to change or qualification based the complete analysis of data.

Clinical failure can occur at any stage of clinical development. Clinical trials may produce negative or inconclusive results.  The FDA or a non-US
regulatory  authority  may  require  us,  to  conduct  additional  clinical  or  preclinical  testing.  Success  in  early  clinical  trials  does  not  mean  that  future  larger
registration clinical trials will be successful because product candidates in later-stage clinical trials may fail to demonstrate sufficient safety and efficacy to
the  satisfaction  of  the  FDA  and  non-U.S.  regulatory  authorities  despite  having  progressed  through  initial  clinical  trials.  A  number  of  companies  in  the
pharmaceutical industry, including those with greater resources and experience than us, have suffered significant setbacks in advanced clinical trials, even
after obtaining promising results in earlier clinical trials.

We may publicly disclose top line or interim data from time to time, which is based on a preliminary analysis of then-available data, and the results
and related findings and conclusions are subject to change following a more comprehensive review of the data related to the particular study or trial. The
top line or interim results that we report may differ from future results of the same studies, or different conclusions or considerations may qualify such
results once additional data have been received and fully evaluated. Even in situations where a clinical stage candidate appears to be benefiting a patient,
that benefit may not be of a permanent nature.  For example, we have previously reported on a patient in cohort 4 of our APVO 436 Phase 1/1b clinical trial
who showed a complete marrow response.  That patient dropped out of the trial during the eleventh cycle of treatment because his/her disease progressed.
Top  line  and  interim  data  also  remain  subject  to  audit  and  verification  procedures,  that  may  result  in  the  final  data  being  materially  different  from  the
preliminary data we previously published. In addition, the achievement of one primary endpoint for a trial does not guarantee that additional co-primary
endpoints or secondary endpoints will be achieved.

27

 
 
Our future clinical trials may not be successful. Moreover, should there be a flaw in a clinical trial, it may not become apparent until the clinical
trial is well advanced. We may also experience numerous unforeseen events during, or as a result of, clinical trials that could delay or prevent our ability to
receive marketing approval or commercialize our product candidates, including:

•

•

•

•

•

•

•

•

•

•

•

•

•

•

•

regulators or Institutional Review Boards (IRBs) may not authorize us or our investigators to commence or continue a clinical trial, conduct
a clinical trial at a prospective trial site, or amend trial protocols, or regulators or IRBs may require that we modify or amend our clinical
trial protocols;

we  may  experience  delays  in  reaching,  or  fail  to  reach,  agreement  on  acceptable  clinical  trial  contracts  or  clinical  trial  protocols  with
prospective trial sites and our contract research organizations (CROs);

regulators may require us to perform additional or unanticipated clinical trials to obtain approval or we may be subject to additional post-
marketing testing, surveillance, or REMS requirements to maintain regulatory approval;

clinical trials of our product candidates may produce negative or inconclusive results, or our studies may fail to reach the necessary level of
statistical significance;

changes in marketing approval policies, laws, regulations, or the regulatory review process during the development period rendering our
data insufficient to obtain marketing approval;

the cost of clinical trials of our product candidates may be greater than we anticipate or we may have insufficient funds for a clinical trial or
to pay the substantial user fees required by the FDA upon the filing of a marketing application;

the  supply  or  quality  of  our  product  candidates  or  other  materials  necessary  to  conduct  clinical  trials  of  our  product  candidates  may  be
insufficient or inadequate;

we may fail to reach an agreement with regulators or IRBs regarding the scope, design, or implementation of our clinical trials;

we may have delays in adding new investigators or clinical trial sites, or we may experience a withdrawal of clinical trial sites;

there may be regulatory questions or disagreements regarding interpretations of data and results, or new information may emerge regarding
our product candidates;

the FDA or comparable foreign regulatory authorities may disagree with our study design, including endpoints, or our interpretation of data
from preclinical studies and clinical trials or find that a product candidate’s benefits do not outweigh its safety risks;

the FDA or comparable foreign regulatory authorities may not accept data from studies with clinical trial sites in foreign countries;

the FDA or comparable regulatory authorities may disagree with our intended indications;

the FDA or comparable foreign regulatory authorities may fail to approve or subsequently find fault with the manufacturing processes or
our contract manufacturer’s manufacturing facility for clinical and future commercial supplies; and

we  may  not  be  able  to  demonstrate  that  a  product  candidate  provides  an  advantage  over  current  standards  of  care  or  current  or  future
competitive therapies in development.

Further, our product candidates may not be approved even if they achieve their primary endpoints in Phase 3 clinical trials or registration trials.
Regardless of any advisory committee recommendation, the FDA may decline to approve the BLA for a number of reasons including, if the clinical benefit,
safety profile or effectiveness of the drug is not deemed by the FDA to warrant approval. The FDA or other non-U.S. regulatory authorities may disagree
with  our  trial  design,  and  our  interpretation  of  data  from  preclinical  studies  and  clinical  trials.  In  particular,  the  FDA  may  not  view  our  data  as  being
clinically  meaningful  or  statistically  persuasive.  In  addition,  any  of  these  regulatory  authorities  may  change  requirements  for  the  approval  of  a  product
candidate even after reviewing and providing comments or advice on a protocol for a pivotal Phase 3 clinical trial. Any of these regulatory authorities may
also approve a product candidate for fewer or more limited indications than we request or may grant approval contingent on the performance of costly post-
marketing  clinical  trials.  The  FDA  or  other  non-U.S.  regulatory  authorities  may  not  approve  the  labeling  claims  that  we  believe  would  be  necessary  or
desirable for the successful commercialization of our product candidates.

28

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
If we experience delays or difficulties in the enrollment of patients in clinical trials, the time to reach critical trial data and receipt of any necessary
regulatory approvals could be delayed.

We may not be able to initiate or continue clinical trials for our product candidates if we are unable to locate and enroll a sufficient number of
eligible patients to participate in these trials as required by the FDA or similar regulatory authorities outside the United States. In addition, some of our
competitors have ongoing clinical trials for product candidates that treat the same indications as our product candidates, and patients who would otherwise
be eligible for our clinical trials may instead enroll in clinical trials of our competitors’ product candidates.  In addition, the global outbreak of the COVID-
19 pandemic makes it more difficult to initiate studies and enroll patients.

Patient enrollment is affected by other factors including:

•

•

•

•

•

•

•

the severity of the disease under investigation;

the patient eligibility criteria for the study in question;

the perceived risks and benefits of the product candidate under study;

our payments for conducting clinical trials;

the patient referral practices of physicians;

the ability to monitor patients adequately during and after treatment; and,

the proximity and availability of clinical trial sites for prospective patients.

Our inability to enroll a sufficient number of patients for clinical trials could result in significant delays and could require us to abandon one or
more clinical trials altogether. Enrollment delays in our clinical trials may result in increased development costs for our product candidates and in delays to
commercially launching our product candidates, if approved, which may cause the value of our company to decline and limit our ability to obtain additional
financing.

Serious adverse events, undesirable side effects or other unexpected properties of our product candidates may be identified that could delay, prevent, or
cause  the  withdrawal  of  regulatory  approval,  limit  the  commercial  potential,  or  result  in  significant  negative  consequences  following  marketing
approval.

Serious adverse events or undesirable side effects caused by, or other unexpected properties of any of our product candidates could cause us or
regulatory authorities to interrupt, delay or halt our manufacturing and distribution operations and could result in a more restrictive label, the imposition of
distribution or use restrictions or the delay or denial of regulatory approval by the FDA or comparable foreign regulatory authorities. If any of our product
candidates  are  associated  with  serious  adverse  events  or  undesirable  side  effects  or  have  properties  that  are  unexpected,  we  may  need  to  abandon  their
development or limit development to certain uses or subpopulations in which the undesirable side effects or other characteristics are less prevalent, less
severe or more acceptable from a risk-benefit perspective. Many compounds that initially showed promise in clinical or earlier stage testing have later been
found to cause undesirable or unexpected side effects that prevented further development of the compound.

As we continue developing our product candidates and initiate clinical trials of our additional product candidates, serious adverse events, or SAEs,
undesirable  side  effects,  relapse  of  disease  or  unexpected  characteristics  may  emerge  causing  us  to  abandon  these  product  candidates  or  limit  their
development to more narrow uses or subpopulations in which the SAEs or undesirable side effects or other characteristics are less prevalent, less severe or
more acceptable from a risk-benefit perspective or in which efficacy is more pronounced or durable. Undesirable side effects, or other unexpected adverse
events or properties of any of our product candidates, could arise or become known either during clinical development or, if approved, after the approved
product has been marketed. If such an event occurs during development, our trials could be suspended or terminated, and the FDA or comparable foreign
regulatory authorities could order us to cease further development of or deny approval of our other product candidates. If such an event occurs, a number of
potentially significant negative consequences may result, including:

•

•

regulatory authorities may require additional warnings on the label or impose distribution or use restrictions;

regulatory authorities may require one or more post-market studies;

29

 
 
 
 
 
 
 
 
 
 
•

•

•

•

we may be required to create a medication guide outlining the risks of such side effects for distribution to patients;

regulatory authorities may require implementation of a Risk Evaluation and Mitigation Strategy, or REMS, Field Safety Corrective Actions
or  equivalent,  which  may  include  safety  surveillance,  restricted  distribution  and  use,  patient  education,  enhanced  labeling,  special
packaging  or  labeling,  expedited  reporting  of  certain  adverse  events,  preapproval  of  promotional  materials  and  restrictions  on  direct-to-
consumer advertising;

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

our reputation may suffer.

Any of these events could prevent us from achieving or maintaining market acceptance of the affected product candidate, or could substantially
increase commercialization costs and expenses, which could delay or prevent us from generating revenue from the sale of our products and materially harm
our business and results of operations.

We depend on third parties to conduct our clinical and non-clinical trials.

We  do  not  have  the  ability  to  independently  conduct  the  clinical  and  non-clinical  trials  required  to  obtain  regulatory  approval  for  our  product
candidates. We depend on third parties, such as independent clinical investigators, contract research organizations, or CROs, and other third-party service
providers to conduct the clinical and non-clinical trials of our product candidates, and we expect to continue to do so. For example, Dr. Scott Stromatt, our
former full-time Chief Medical Officer, is now providing clinical trial and medical affairs oversight duties as an independent consultant. We rely heavily on
Dr. Stromatt and these other third parties for successful execution of our clinical and non-clinical trials, but we do not exercise day-to-day control over their
activities.

While  we  have  agreements  governing  the  activities  of  third  parties,  we  have  limited  influence  and  control  over  their  actual  performance  and
activities. For instance, our third-party service providers are not our employees, and except for remedies available to us under our agreements with such
third parties we cannot control whether or not they devote sufficient time and resources to our ongoing clinical, non-clinical, and preclinical programs. Our
third-party service providers may also have relationships with other entities, some of which may be our competitors, for whom they may also be conducting
trials  or  other  therapeutic  development  activities  that  could  harm  our  competitive  position.    If  these  third  parties  do  not  successfully  carry  out  their
contractual  duties,  meet  expected  deadlines  or  conduct  our  preclinical  studies  or  clinical  trials  in  accordance  with  regulatory  requirements  or  our  stated
protocols, 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 trials may be repeated, extended, delayed, or terminated, we may not be able to obtain, or may be delayed
in obtaining, marketing approvals for our product candidates, we may not be able to, or may be delayed in our efforts to, successfully commercialize our
product candidates, or we or they may be subject to regulatory enforcement actions.

Our reliance on third-party service providers does not relieve us of our regulatory responsibilities, including ensuring that our trials are conducted
in accordance with the FDA-approved good clinical practices, or GCPs, and the plans and protocols contained in the relevant regulatory application. In
addition,  these  organizations  and  individuals  may  not  complete  these  activities  on  our  anticipated  or  desired  timeframe.  We  also  may  experience
unexpected cost increases that are beyond our control. Problems with the timeliness or quality of the work of a contract research organization may lead us
to seek to terminate the relationship and use an alternative service provider, which may prove difficult and/or costly and result in a delay of our trials. In
addition, business disruptions arising from the COVID-19 pandemic could negatively affect the ability of some of the independent clinical investigators,
contract research organizations and other third-party service providers that conduct our clinical and non-clinical trials of our product candidates. Any delay
in or inability to complete our trials could delay or prevent the development, approval, and commercialization of our product candidates.

If CROs or other third parties assisting us or our study sites fail to comply with applicable GCPs, the clinical data generated in our clinical trials
may be deemed unreliable and the FDA or its non-U.S. counterparts may require us to perform additional clinical trials before approving our marketing
applications.  We  or  they  may  also  face  regulatory  enforcement  action.    We  cannot  assure  you  that,  upon  inspection,  the  FDA  or  non-U.S.  regulatory
agencies will determine that any of our clinical trials comply with GCPs. In addition, our clinical trials must be conducted with product produced under
GMPs and similar regulations outside of the United States. Our failure, or the failure of our product manufacturers, to comply with these regulations may
require us to repeat or redesign clinical trials, or conduct additional trials, which would increase our development costs and delay or impact the likelihood
of regulatory approval.

30

 
 
 
 
 
 
If third parties do not carry out their duties under their agreements with us, if the quality or accuracy of the data they obtain is compromised due to
the failure to adhere to our clinical protocols, including dosing requirements, or regulatory requirements, or if they otherwise fail to comply with clinical
trial  protocols  or  meet  expected  deadlines,  our  clinical  trials  may  not  meet  regulatory  requirements.  If  our  clinical  trials  do  not  meet  regulatory
requirements or if these third parties need to be replaced, our clinical trials may be extended, delayed, suspended or terminated.

Agreements with third parties conducting or otherwise assisting with our clinical or preclinical studies might terminate for a variety of reasons,
including  a  failure  to  perform  by  the  third  parties.  If  any  of  our  relationships  with  these  third  parties  terminate,  we  may  not  be  able  to  enter  into
arrangements with alternative providers or to do so on commercially reasonable terms. Switching or adding additional third parties involves additional cost
and requires management time and focus. In addition, there is a natural transition period when a new third party commences work. As a result, if we need
to enter into alternative arrangements, it could delay our product development activities and adversely affect our business. Though we carefully manage our
relationships with our third parties, there can be no assurance that we will not encounter challenges or delays in the future or that these delays or challenges
will not have a material adverse impact on our business, financial condition and prospects, and results of operations.

If  any  of  these  events  occur,  we  may  not  be  able  to  obtain  regulatory  approval  of  our  product  candidates  or  succeed  in  our  efforts  to  create
approved line extensions for certain of our existing products or generate additional useful clinical data in support of these products. Moreover, if we are
unable to obtain any necessary third-party services on acceptable terms or if these service providers do not successfully carry out their contractual duties or
meet expected deadlines, our efforts to obtain regulatory approvals for our product candidates may be delayed or prevented.

Certain  of  our  product  candidates  have  received  orphan  drug  designation  from  the  FDA.  However,  there  is  no  guarantee  that  we  will  be  able  to
maintain  this  designation,  receive  this  designation  for  any  of  our  other  product  candidates,  or  receive  or  maintain  any  corresponding  benefits,
including periods of exclusivity.

Certain  of  our  product  candidates  have  received  orphan  drug  designation.  We  may  also  seek  orphan  drug  designation  for  our  other  product
candidates, as appropriate. While orphan drug designation does provide us with certain advantages, it neither shortens the development time or regulatory
review time of a product candidate nor gives the product candidate any advantage in the regulatory review or approval process.

Generally, if a product candidate with orphan drug designation subsequently receives marketing approval before another product considered by the
FDA to be the same for the same orphan indication, the product is entitled to a period of marketing exclusivity, which precludes the FDA from approving
another marketing application for the same drug or biologic for the same indication for a period of seven years in the United States.

We may not be able to obtain any future orphan drug designations that we apply for. Orphan drug designations do not guarantee that we will be
able  to  successfully  develop  our  product  candidates,  and  there  is  no  guarantee  that  we  will  be  able  to  maintain  any  orphan  drug  designations  that  we
receive. For instance, orphan drug designations may be revoked if the FDA finds that the request for designation contained an untrue statement of material
fact or omitted material information, or if the FDA finds that the product candidate was not eligible for designation at the time of the submission of the
request.

Moreover, even if we are able to receive and maintain orphan drug designations, we may ultimately not receive any period of regulatory exclusivity
if our product candidates are approved. For instance, we may not receive orphan product regulatory exclusivity if the indication for which we receive FDA
approval is broader than the orphan drug designation. Orphan exclusivity may also be lost for the same reasons that orphan drug designation may be lost.
Orphan exclusivity may further be lost if we are unable to assure a sufficient quantity of the product to meet the needs of patients with the rare disease or
condition.

Even if we obtain orphan exclusivity for any of our current or future product candidates, that exclusivity may not effectively protect the product
from  competition  as  different  products  can  be  approved  for  the  same  condition  or  products  that  are  the  same  as  ours  can  be  approved  for  different
conditions. Even after an orphan product is approved, the FDA can also subsequently approve a product containing the same principal molecular features
for the same condition if the FDA concludes that the later product is clinically superior. The FDA may further grant orphan drug designation to multiple
sponsors for the same compound or active molecule and for the same indication. If

31

 
another sponsor receives FDA approval for such product before we do, we would be prevented from launching our product in the United States for the
orphan  indication  for  a  period  of  at  least  seven  years,  unless  we  can  demonstrate  clinical  superiority.  Moreover,  third-party  payors  may  reimburse  for
products off-label even if not indicated for the orphan condition.

Commercialization Risks

Our ability to grow revenues and execute on our long-term strategy depends heavily on our ability to discover, develop, and obtain marketing approval
for our product candidates.

We currently have no products approved for commercial distribution. We have invested a significant portion of our efforts and financial resources
in  the  development  of  our  product  candidates.    Our  business  depends  on  the  successful  development  and  commercialization  of  our  product  candidates,
which  will  require  additional  clinical  and  non-clinical  development,  regulatory  approval,  commercial  manufacturing  arrangements,  establishment  of  a
commercial organization, significant marketing efforts, and further investment, which may never occur. Our ability to generate revenues is substantially
dependent on our ability to develop, obtain regulatory approval for, and then successfully commercialize our product candidates. Except for the revenues
from previously sold products, we currently generate no revenues from sales of any products, and we may never be able to develop or commercialize a
marketable product.

In order for us to achieve our long-term business objectives, we will need to successfully discover and/or develop and commercialize our product
candidates. Although we have made, and expect to continue to make, significant investments in research and development, we have had only a limited
number of our internally-discovered product candidates reach the clinical development stage. We currently have one clinical-stage candidate, APVO436,
which is built on the ADAPTIR platform. Drug discovery and development is a complex, time-consuming and expensive process that is fraught with risk
and  a  high  rate  of  failure.  Our  product  candidates  are  susceptible  to  the  risks  of  failure  inherent  at  any  stage  of  product  development,  including  the
appearance  of  unexpected  or  unacceptable  adverse  events  or  failure  to  demonstrate  efficacy  in  clinical  trials.  For  example,  in  2018,  we  announced  the
discontinuation of development of APVO414 and otlertuzumab as a result of clinical trial results. In addition, in October 2019, we announced our decision
to  discontinue  development  of  APVO210,  a  novel  investigational  bispecific  antibody  candidate  under  development  for  the  treatment  of  autoimmune
diseases. The decision followed the review of data from Phase 1 multiple ascending dose (MAD) clinical study of APVO210 in healthy volunteers that
suggests that APVO210 would not meet the desired target product profile for future commercialization. Specifically, the clinical data showed evidence of
increasing titers of ADA with repeated doses of APVO210, which had varying impact on APVO210 drug levels in subjects’ blood. Failure to successfully
discover and/or develop, obtain marketing approval for and commercialize additional products and product candidates would likely have a material adverse
effect on our ability to grow revenues and improve our financial condition. If we are required to conduct additional clinical trials or other testing of our
product candidates that we develop beyond those that we currently expect, if we are unable to successfully complete clinical trials of our product candidates
or other testing, if the results of these trials or tests are not positive or are only modestly positive, or if there are safety concerns, we may be delayed in
obtaining  marketing  approval  for  our  product  candidates,  not  obtain  marketing  approval  at  all,  obtain  approval  for  limited  indications  or  patient
populations, with a label without claims necessary for us to successfully market or products, or with significant labeled warnings. We may also be subject
to additional post-marketing testing requirements, surveillance requirements, or REMS. To the extent any of the foregoing should occur, our business may
be materially harmed.

We may not be successful in our efforts to use and further develop our ADAPTIR or ADAPTIR-FLEX platforms.

A key element of our strategy is to expand our product pipeline of immunotherapeutics based on our ADAPTIR and ADAPTIR-FLEX platform
technologies. We plan to select and create product candidates for early development, potentially with other collaborative partners. We expect to continue to
develop the platform to address unmet medical needs through directed cytokine delivery via monospecifics and bispecifics in areas including oncology, and
multispecific  molecules  in  oncology  and  other  therapeutic  areas.  Our  goal  is  to  leverage  this  technology  to  make  targeted  investment  in  monospecific,
bispecific,  and  multispecific  ADAPTIR  and  ADAPTIR-FLEX  therapeutics.  Even  if  we  are  successful  in  continuing  to  build  our  pipeline,  the  potential
product candidates that we identify may not be suitable for clinical development, including as a result of being shown to have harmful side effects or other
characteristics  that  indicate  that  they  are  unlikely  to  be  products  that  will  receive  marketing  approval  and  achieve  market  acceptance.  If  we  do  not
successfully develop and commercialize product candidates

32

 
based on our ADAPTIR and ADAPTIR-FLEX platform technologies, our ability to obtain product revenues in future periods may be adversely affected,
which likely would result in harm to our financial position and our financial prospects, and adversely affect our stock price.

We face substantial competition.

The development and commercialization of new biotechnology products is highly competitive and subject to rapid technological advances. We may
face future competition with respect to our current product candidates and any product candidates we may seek to develop or commercialize in the future
obtained from other companies and governments, universities, and other non-profit research organizations. Our competitors may develop products that are
safer, more effective, more convenient, or less costly than any products that we may develop or market, or may obtain marketing approval for their products
from the FDA, or equivalent foreign regulatory bodies more rapidly than we may obtain approval for our product candidates. Our competitors may have
greater resources and may devote greater resources to research and develop their products, research and development capabilities, adapt more quickly to
new  technologies,  scientific  advances  or  patient  preferences  and  needs,  initiate  or  withstand  substantial  price  competition  more  successfully,  or  more
effectively negotiate third-party licensing and collaborative arrangements.

We believe that our most significant competitors in the oncology market include: AbbVie Inc., Aduro, Inc., Affirmed, Amgen Inc., AnaptysBio,
Inc.,  Astellas  Pharma  Inc.,  Bayer  AG,  Biogen  Idec  Inc.,  Boehringer  Ingelheim  GmbH,  F-Star  Biotechnology  Ltd.,  Genentech  Inc.  (a  subsidiary  of  F.
Hoffmann-La Roche Ltd.), Genmab A/S, GlaxoSmithKline plc, Grifols USA LLC, Bristol Myers Squibb, ImmunoGen, Inc., Immunomedics, Inc., Janssen
BioTech  Inc.,  Johnson  &  Johnson,  Macrogenics,  Inc.,  Novartis  International  AG,  Pieris  Pharmaceuticals,  Inc.,  Sanofi-Aventis  US  LLC,  Takeda
Pharmaceuticals U.S.A., Inc., Teneobio, Inc., Xencor, Inc. and Zymeworks Biopharmaceuticals, Inc. We expect to compete on the basis of product efficacy,
safety, ease of administration, price and economic value compared to drugs used in current practice or currently being developed. If we are not successful
in  demonstrating  these  attributes,  physicians  and  other  key  healthcare  decision  makers  may  choose  other  products  over  any  products  we  successfully
develop, switch from our products, to new products or choose to use our products only in limited circumstances, which could adversely affect our business,
financial condition and results of operations.

Any of our product candidates, if approved, may become subject to unfavorable pricing regulations or third-party coverage and reimbursement policies,
which would harm our business.

The  success  of  our  product  candidates,  if  approved,  will  depend  upon,  among  other  things,  their  acceptance  by  physicians,  patients,  third-party
payors, and other members of the medical community as a therapeutic and cost-effective alternative to competing products and treatments. If any of our
product candidates do not achieve and maintain an adequate level of acceptance, we may not generate material revenues from sales of these products. The
degree  of  market  acceptance  of  our  products  will  depend  on  a  number  of  factors,  including:  our  ability  to  provide  acceptable  evidence  of  safety  and
efficacy; the prevalence and severity of any side effects; availability, relative cost and relative efficacy of alternative and competing treatments; the ability
to offer our products for sale at competitive prices; our ability to continuously supply the market without interruption; the relative convenience and ease of
administration; the willingness of the target patient population to try new products and of physicians to prescribe these products; the strength of marketing
and distribution support; publicity concerning our products or competing products and treatments; and the sufficiency of coverage or reimbursement by
third parties.

Legislative or healthcare 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 ACA was enacted, which substantially changed the way health care is financed by both governmental and private insurers, and significantly impacted
the U.S. pharmaceutical industry. However, some provisions of the ACA have yet to be fully implemented and certain provisions have been subject to legal
and  political  challenges,  as  well  as  efforts  to  repeal,  replace  delay,  circumvent,  or  loosen  certain  aspects  of  the  ACA  or  mandates  required  thereby.
Additionally,  Congress  has  considered  legislation  that  would  repeal  or  repeal  and  replace  all  or  part  of  the  ACA.  While  Congress  has  not  passed
comprehensive repeal legislation, it has enacted laws that modify certain provisions of the ACA, such as removing penalties as of January 1, 2019 for not
complying with the ACA’s individual mandate to carry health insurance, delaying the implementation of certain

33

 
ACA-mandated  fees,  and  increasing  the  point-of-sale  discount  that  is  owed  by  pharmaceutical  manufacturers  who  participate  in  Medicare  Part  D.
Additionally, on December 14, 2018, a Texas U.S. District Court Judge ruled that the ACA is unconstitutional in its entirety because the individual mandate
was repealed by Congress as part of the Tax Cuts & Jobs Act and the case is currently pending before the United States Supreme Court. It is unclear how
this decision, subsequent appeals, and other efforts to repeal and replace the ACA will impact the ACA and our business. We continue to evaluate how the
ACA and recent efforts to repeal and replace or limit the implementation of the ACA will impact our business.

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, created measures for spending reductions by Congress. A Joint Select Committee on Deficit Reduction,
tasked with recommending a targeted deficit reduction of at least $1.2 trillion for the years 2013 through 2021, was unable to reach required goals, thereby
triggering the legislation’s automatic reduction to several government programs. This includes aggregate reductions of Medicare payments to providers of 2
percent per fiscal year. These reductions went into effect on April 1, 2013 and, due to subsequent legislative amendments to the statute, will remain in
effect through 2030 unless additional Congressional action is taken.

Additionally,  there  has  been  heightened  governmental  scrutiny  recently  over  the  manner  in  which  manufacturers  set  prices  for  their  marketed
products. For example, there have been several recent Congressional inquiries and proposed and enacted federal and state legislation designed to, among
other things, bring more transparency to drug pricing, review the relationship between pricing and manufacturer patient programs, and reform government
program  reimbursement  methodologies  for  drug  products,  including  by  tying  reimbursement  to  the  price  of  products  in  other  developed  countries.  For
example, proposals  have  been  made  to  increase  drug  manufacturer  competition,  increase  the  negotiating  power  of  certain  federal  healthcare  programs,
incentivize manufacturers to lower the list price of their products, and reduce the out of pocket costs of drug products paid by consumers. 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. On January 21, 2021, Joe Biden
was sworn in as the U.S. president, and the Democratic Party obtained an equal number of seats in the U.S. Senate as the Republican Party, as well as
maintained control of the U.S. House of Representatives. Many expect that the Biden administration will pursue stronger healthcare consumer protections,
and  it  may  act  to  overturn  some  of  the  prior  Trump  administration  initiatives;  however,  the  legislative  and  regulatory  agendas,  as  they  relate  to  the
healthcare and pharmaceutical industries and the economy as a whole, of the Biden administration and the U.S. Congress currently remain uncertain. Any
new laws and initiatives may result in additional reductions in Medicare and other healthcare funding or impose additional regulatory requirements on drug
development or approval, which could have a material adverse effect on our future customers and accordingly, our financial operations.

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  any  product  candidates  we
successfully develop or additional pricing pressures.

Manufacture  of  our  product  candidates,  especially  in  large  quantities,  is  complex  and  time  consuming.  The  loss  of  any  of  our  third-party
manufacturers,  or  delays  or  problems  in  the  manufacture  our  product  candidates,  could  result  in  product  shortages  and/or  delays  in  clinical
development.

We do not have manufacturing capabilities and do not plan to develop such capacity in the foreseeable future. We depend on a limited number of
sole source third-party suppliers for our product candidates. Accordingly, our ability to develop and deliver products in a timely and competitive manner
and to enable us to conduct our development programs depends on our third-party manufacturers being able to continue to meet our ongoing clinical trial
needs and perform their contractual obligations. In order to successfully develop and commercialize our product candidates in a timely manner, we and our
third-party manufacturers must be able to develop and execute on manufacturing processes and reach agreement on contract terms.

34

 
Our  current  and  anticipated  future  dependence  upon  others  for  the  manufacture  of  our  product  candidates  or  any  product  that  we  develop  may
adversely affect our future profit margins and our ability to commercialize any products that receive marketing approval on a timely and competitive basis.
In addition, any performance failure on the part of our existing or future manufacturers could delay clinical development or marketing approval.

If  these  third-party  manufacturers  do  not  successfully  carry  out  their  contractual  duties,  meet  expected  deadlines  or  manufacture  our  product
candidates  in  accordance  with  regulatory  requirements,  if  there  are  disagreements  between  us  and  such  parties,  or  if  such  parties  are  unable  to  expand
capacities to support commercialization of any of our product candidates for which we obtain marketing approval, we may not be able to produce, or may
be  delayed  in  producing  sufficient  product  candidates  to  meet  our  supply  requirements.  Any  delays  in  obtaining  adequate  supplies  with  respect  to  our
product candidates and components may delay the development or commercialization of our product candidates.

We may not succeed in our efforts to establish manufacturing relationships or other alternative arrangements for any of our product candidates,
components, and programs. Our product candidates may compete with other products and product candidates for access to manufacturing facilities. There
are a limited number of manufacturers that operate under GMP regulations and that are both capable of manufacturing for us and willing to do so.

If our existing third-party manufacturers, or the third parties that we engage in the future to manufacture a product or component for commercial
sale or for our clinical trials should cease to continue to do so for any reason, we likely would experience delays in obtaining sufficient quantities of our
product candidates for us to meet commercial demand or to advance our clinical trials while we identify and qualify replacement suppliers. These third-
party facilities may also be affected by natural disasters, such as floods or fire, or such facilities could face manufacturing issues, such as contamination or
regulatory  findings  following  a  regulatory  inspection  of  such  facility.  In  such  instances,  we  may  need  to  locate  an  appropriate  replacement  third-party
relationship, which may not be readily available or on acceptable terms, which would cause additional delay and increased expense. The addition of a new
or alternative manufacturer may also require FDA approvals and may have a material adverse effect on our business.

If for any reason we are unable to obtain adequate supplies of our product candidates or the components used to manufacture them, it will be more
difficult for us to develop our product candidates and compete effectively. Further, even if we do establish such collaborations or arrangements, our third-
party manufacturers may breach, terminate, or not renew these agreements.

We or our third-party manufacturers may also encounter shortages in the raw materials or therapeutic substances necessary to produce our product
candidates in the quantities needed for our clinical trials or, if our product candidates are approved, in sufficient quantities for commercialization or to meet
an increase in demand. Such shortages may occur for a variety of reasons, including capacity constraints, delays or disruptions in the market, and shortages
caused by the purchase of such materials by our competitors or others. We may also not be able to obtain such materials on favorable terms as a result of
global trade policies.  Our or our third-party manufacturers’ failure to obtain the raw materials, therapeutic substances, or active pharmaceutical ingredients
necessary to manufacture sufficient quantities of our product candidates may have a material adverse effect on our business.

All of our current product candidates are biologics. Our product candidates must be made consistently and in compliance with a clearly defined
manufacturing process. Problems may arise during manufacturing for a variety of reasons, including problems with raw materials, equipment malfunction
or  replacement  and  failure  to  follow  specific  protocols  and  procedures.  Slight  deviations  anywhere  in  the  manufacturing  process,  including  obtaining
materials, maintaining master seed or cell banks and preventing genetic drift, seed or cell growth, fermentation and contamination including from, among
other things, particulates, filtration, filling, labeling, packaging, storage and shipping, and quality control testing, may result in lot failures or manufacturing
shut-down, delays in the release of lots, product recalls, spoilage or regulatory action. Due to COVID-19, our third-party manufacturers may experience
difficulties that impact our product candidates.

Additionally,  our  development  and  commercialization  strategy  involves  entering  into  arrangements  with  corporate  and  academic  collaborators,
contract research organizations, distributors, third-party manufacturers, licensors, licensees and others to conduct development work, manage or conduct
our  clinical  trials,  manufacture  our  product  candidates  and  market  and  sell  our  products  outside  of  the  United  States  and  maintaining  our  existing
arrangements with respect to the commercialization or manufacture of our products. We may not have the expertise or the resources to conduct all of these
activities for all products and product candidates on our own and, as a result,

35

 
are  particularly  dependent  on  third  parties  in  many  areas.  Any  current  or  future  arrangements  for  development  and  commercialization  may  not  be
successful, as the amount and timing of resources that third parties devote to developing, manufacturing, and commercializing our products candidates are
not within our control. If we are not able to establish or maintain agreements relating our product candidates in development, our results of operations and
prospects would be materially and adversely affected.

Any  loss  of  a  third-party  manufacturer,  any  delays,  or  problems  in  the  manufacture  of  our  products,  or  termination  of  any  arrangements  for
development and commercialization of our products could have a material adverse effect on our business, operations, results of operations and financial
condition. We may be required to replace our manufacturer and if this were to occur, we may incur added costs and delays in identifying and qualifying any
such replacements. We may also not be able to enter into such arrangements on favorable commercial terms.

Failure of our third-party manufacturers to successfully manufacture material that conforms to our specifications and the FDA’s or foreign regulatory
authorities’ strict regulatory requirements, may prevent regulatory approval of those manufacturing facilities.

We  rely  on  third  parties  to  manufacture  all  clinical  trial  materials  for  our  product  candidates,  and  we  will  rely  on  third  parties  to  manufacture
commercial supplies, if any such product candidates are ultimately approved for commercial sale. Manufacturers of our product candidates and therapeutic
substances must comply with GMP requirements enforced by the FDA that are applicable to both finished products and their active components used both
for  clinical  and  commercial  supply.  The  FDA  enforces  these  requirements  through  its  facilities  inspection  program.  Our  product  candidates,  including
APVO436  and  ALG.APV-527  will  not  be  approved  for  marketing  by  the  FDA  or  other  foreign  regulatory  authorities  unless  the  FDA  or  their  foreign
equivalents  also  approve  the  facilities  used  by  our  third-party  manufacturers  to  produce  them  for  commercialization.  If  our  third-party  manufacturers
cannot successfully manufacture material that conforms to our specifications and the FDA’s or foreign regulatory authorities’ strict regulatory requirements,
the FDA or their foreign counterparts will not approve their manufacturing facilities, which would result in significant delays in obtaining FDA or foreign
marketing approvals for our product candidates.   If this were to occur, we may also never receive marketing approval, we may need to repeat clinical trials,
we  may  need  to  undertake  costly  corrective  actions,  including  product  recalls,  we  may  risk  harm  to  subjects  or  patients,  and  we  may  face  enforcement
actions.  

While we are ultimately responsible for the manufacture of our product candidates, other than through our contractual arrangements, we have little
control over our manufacturers’ compliance with these regulations and standards. If the FDA or a comparable foreign regulatory authority does not approve
these  facilities  for  the  manufacture  of  our  product  candidates  or  if  it  withdraws  any  such  approval  in  the  future,  we  may  need  to  find  alternative
manufacturing  facilities,  which  would  significantly  impact  our  ability  to  develop,  obtain  and  maintain  regulatory  approval  for  or  market  our  product
candidates, if approved. Any new manufacturers would need to either obtain or develop the necessary manufacturing know-how, and obtain the necessary
equipment and materials, which may take substantial time and investment. We must also receive FDA approval for the use of any new manufacturers for
commercial supply.

We and our third-party manufacturers may not be able to meet these manufacturing process requirements for any of our current product candidates,
all of which have complex manufacturing processes, which make meeting these requirements even more challenging. Due to COVID-19, our third-party
manufacturers may experience difficulties that impact our product candidates. If we are unable to develop manufacturing processes for our clinical product
candidates that satisfy these requirements, we will not be able to supply sufficient quantities of test material to conduct our clinical trials in a timely or cost
effective manner, and as a result, our development programs will be delayed, our financial performance will be adversely impacted and we will be unable
to meet our long-term goals.

Changes in product candidate manufacturing or formulation may result in additional costs or delay.

As product candidates are developed through preclinical studies to late-stage clinical trials toward approval and commercialization, it is common
that various aspects of the development program, such as manufacturing methods, manufacturing sites, and formulation, are altered along the way in an
effort to optimize processes and results. Any of these changes could cause our product candidates to perform differently and affect the results of planned
clinical  trials  or  other  future  clinical  trials  conducted  with  the  altered  materials.  Such  changes  may  also  require  additional  testing,  clinical  trials,  FDA
notification, or FDA approval. Any of the foregoing could limit our future revenues and growth.

36

 
Regulatory and Compliance Risks

Our long-term success depends, in part, upon our ability to develop, receive regulatory approval for and commercialize our product candidates.

Our product candidates and the activities associated with their development, including testing, manufacture, recordkeeping, storage, and approval,
are subject to comprehensive regulation by the FDA and other regulatory agencies in the United States and by comparable authorities in other countries.
Failure to obtain regulatory approval for a product candidate will prevent us from commercializing the product candidate. We have limited resources for
use  in  preparing,  filing,  and  supporting  the  applications  necessary  to  gain  regulatory  approvals  and  expect  to  rely  on  third-party  contract  research
organizations and consultants to assist us in this process.

The  FDA  and  other  comparable  regulatory  agencies  in  foreign  countries  impose  substantial  and  rigorous  requirements  for  the  development,
production, marketing authorization and commercial introduction of drug products. These requirements include pre-clinical, laboratory and clinical testing
procedures,  sampling  activities,  clinical  trials,  and  other  costly  and  time-consuming  procedures.  In  addition,  regulation  is  not  static,  and  regulatory
authorities, including the FDA evolve in their staff interpretations and practices and may impose more stringent or different requirements than currently in
effect, which may adversely affect our planned and ongoing drug development and/or our sales and marketing efforts.

In the United States, to obtain approval from the FDA to market any of our future biologic products, we will be required to submit a BLA to the
FDA. Ordinarily, the FDA requires a sponsor to support a BLA with substantial evidence of the product’s safety, purity, and potency in treating the targeted
indication based on data derived from adequate and well-controlled clinical trials, including Phase 3 safety and efficacy trials conducted in patients with the
disease or condition being targeted.

Developing  and  obtaining  regulatory  approval  for  product  candidates  is  a  lengthy  process,  often  taking  a  number  of  years,  is  uncertain  and  is
expensive.  All  of  the  product  candidates  that  we  are  developing,  or  may  develop  in  the  future,  require  research  and  development,  pre-clinical  studies,
nonclinical  testing,  and  clinical  trials  prior  to  seeking  regulatory  approval,  and  commencing  commercial  sales.  In  addition,  we  may  need  to  address  a
number of technological challenges in order to complete development of our product candidates. As a result, the development of product candidates may
take longer than anticipated or not be successful at all.

Our product candidate development costs will also increase if we experience delays in testing or approvals, and we may not have sufficient funding
to complete the testing and approval process for any of our product candidates. We may be required to obtain additional funds to complete clinical trials
and  prepare  for  possible  commercialization  of  our  product  candidates.  We  do  not  know  whether  any  preclinical  tests  or  clinical  trials  above  what  we
currently have planned will be required, will begin as planned, will need to be restructured, or will be completed on schedule, or at all. Significant delays
relating  to  any  preclinical  or  clinical  trials  also  could  shorten  any  periods  during  which  we  may  have  the  exclusive  right  to  commercialize  our  product
candidates or allow our competitors to bring products to market before we do. This may prevent us from receiving marketing approvals and impair our
ability to successfully commercialize our product candidates and may harm our business and results of operations. In addition, many of the factors that
cause, or lead to, delays in clinical trials may ultimately lead to the denial of marketing approval of any of our product candidates. If any of this occurs, our
business, financial condition, results of operations, and prospects will be materially harmed.

Generally,  no  product  can  receive  FDA  approval,  marketing  authorization  from  the  European  Commission  or  the  competent  authorities  of  the  EU
Member States, or approval from comparable regulatory agencies in foreign countries unless data generated in human clinical trials demonstrates both
safety and efficacy for each target indication in accordance with such authority’s standards.

The  large  majority  of  product  candidates  that  begin  human  clinical  trials  fail  to  demonstrate  the  required  safety  and  efficacy  characteristics
necessary for marketing approval. Failure to demonstrate the safety and efficacy of any of our product candidates for each target indication in clinical trials
would prevent us from obtaining required approvals from regulatory authorities, which would prevent us from commercializing those product candidates.
Negative  or  inconclusive  results  from  the  clinical  trials  or  adverse  medical  events  during  the  trials  could  lead  to  requirements  that  trials  be  repeated  or
extended,  or  that  additional  trials  be  conducted,  any  of  which  may  not  be  clinically  feasible  or  financially  practicable,  that  the  conduct  of  trials  be
suspended, or that a program be terminated.

37

 
Any regulatory approval we ultimately obtain may limit the indicated uses for the product or subject the product to restrictions or post-approval
commitments that render the product commercially non-viable. Securing regulatory approval requires the submission of extensive non-clinical and clinical
data,  information  about  product  manufacturing  processes  and  inspection  of  facilities  and  supporting  information  to  the  regulatory  authorities  for  each
therapeutic indication to establish the product’s safety and efficacy. If we are unable to submit the necessary data and information, for example, because the
results of clinical trials are not favorable, or if the applicable regulatory authority delays reviewing or does not approve our applications, we will be unable
to obtain regulatory approval.

Delays  in  obtaining  or  failure  to  obtain  regulatory  approvals  may:  delay  or  prevent  the  successful  commercialization  of  any  of  the  products  or

product candidates in the jurisdiction for which approval is sought; diminish our competitive advantage; and defer or decrease our receipt of revenue.

Some  of  our  product  candidates  previously  in  development  experienced  regulatory  and/or  clinical  setbacks.  Clinical  development  has  been
discontinued for product candidates otlertuzumab, APVO414, and APVO210. Both APVO414 and APVO210 were discontinued after patients developed
ADA. Most  recently,  in  2019,  we  elected  to  discontinue  the  APVO210  development  program  following  the  review  of  data  from  the  Phase  1  multiple
ascending dose (MAD) clinical study of APVO210 in healthy volunteers that suggests that APVO210 would not meet the desired target product profile for
future commercialization. Specifically, the clinical data showed evidence of increasing titers of ADA with repeated doses of APVO210, which had varying
impact on APVO210 drug levels in subjects’ blood.  The cause of the ADA is uncertain; however, we believe that appearance of ADA is related to the
mechanism of action of APVO210, and not due to the structure, or sequences characteristic of the ADAPTIR platform.   Although we have re-designed
certain components of the ADAPTIR platform based on what we have learned in prior clinical, trials, there is no guarantee that the occurrence of ADA or
other clinical setbacks will not occur in the development of our existing and future ADAPTIR product candidates.

The procedures to obtain marketing approvals vary among countries and can involve additional clinical trials or other pre-filing requirements. The
time required to obtain foreign regulatory approval may differ from that required to obtain FDA approval. The foreign regulatory approval process may
include all the risks associated with obtaining FDA approval, or different or additional risks. Regulatory agencies may have varying interpretations of the
same data, and approval by one regulatory authority does not ensure approval by regulatory authorities in other jurisdictions. Accordingly, approval by the
FDA does not ensure approval by the regulatory authorities in other countries, and approval by one foreign regulatory authority does not ensure approval
by the FDA or regulatory authorities in other foreign countries. Failure to obtain regulatory approval in one jurisdiction, however, may impact the decision
of other jurisdictions.  We may not be able to file for regulatory approvals and may not receive necessary approvals to commercialize our products and
products in development in any market on a timely basis, if at all.

Our product candidates are and will continue to be subject to ongoing obligations and continued regulatory review, which may result in significant
additional expense.  We may be subject to penalties if we fail to comply with regulatory requirements or experience unanticipated problems with our
products.

We  and  our  product  candidates  are  subject  to  extensive  and  ongoing  requirements  of  and  review  by  the  FDA  and  other  regulatory  authorities,
including requirements related to the conduct of clinical and pre-clinical studies, manufacturing processes, post-approval clinical data, labeling, packaging,
distribution,  adverse  event  reporting,  storage,  recordkeeping,  export,  import,  advertising,  marketing,  and  promotional  activities  for  such  product.  These
requirements further include submissions of safety and other post-marketing information, including manufacturing deviations and reports, registration and
listing  requirements,  the  payment  of  annual  fees,  continued  compliance  with  GMP-requirements  relating  to  manufacturing,  quality  control,  quality
assurance, and corresponding maintenance of records and documents, and requirements regarding the distribution of samples to physicians.

FDA and comparable foreign regulatory authorities will continue to closely monitor the safety profile of any product even after approval. If the
FDA  or  comparable  foreign  regulatory  authorities  become  aware  of  new  safety  information  after  approval  of  any  of  our  product  candidates,  they  may,
among  other  actions,  withdraw  approval,  require  labeling  changes  or  establishment  of  a  REMS  or  similar  strategy,  impose  significant  restrictions  on  a
product’s indicated uses or marketing, or impose ongoing requirements for potentially costly post-approval studies or post-market surveillance. Any such
restrictions could limit sales of the product.

We and any of our collaborators could be subject to periodic unannounced inspections by the FDA to monitor and ensure compliance with GMPs

and other FDA regulatory requirements. Application holders must further notify

38

 
the FDA, and depending on the nature of the change, obtain FDA pre-approval for product and manufacturing changes.  In  addition,  later  discovery  of
previously  unknown  adverse  events  or  that  the  product  is  less  effective  than  previously  thought  or  other  problems  with  our  products,  manufacturers  or
manufacturing processes, or failure to comply with regulatory requirements both before and after approval, may yield various results, including:

•

•

•

•

•

•

•

•

•

•

•

•

•

•

•

•

•

•

•

•

•

restrictions on manufacturing or distribution, or marketing of such products;

modifications to promotional pieces and product labels;

issuance of corrective information;

requirements to conduct post-marketing studies or other clinical trials;

clinical holds or termination of clinical trials;

requirements to establish or modify a REMS or a similar strategy;

changes to the way the product is administered;

liability for harm caused to patients or subjects;

reputational harm;

the product becoming less competitive;

warning, untitled, or cyber letters;

suspension of marketing or withdrawal of the products from the market;

regulatory  authority  issuance  of  safety  alerts,  Dear  Healthcare  Provider  letters,  press  releases,  or  other  communications  containing
warnings or other safety information about the product;

refusal to approve pending applications or supplements to approved applications that we submit;

recalls of products;

fines, restitution or disgorgement of profits or revenues;

suspension or withdrawal of marketing approvals;

refusal to permit the import or export of our products;

product seizure or detention;

FDA  debarment,  suspension  and  debarment  from  government  contracts,  and  refusal  of  orders  under  existing  government  contracts,
exclusion from federal healthcare programs, consent decrees, or corporate integrity agreements; or

injunctions or the imposition of civil or criminal penalties, including imprisonment.

Any of these events could prevent us from achieving or maintaining product approval and market acceptance of the particular product candidate, if
approved, or could substantially increase the costs and expenses of developing and commercializing such product, which in turn could delay or prevent us
from generating significant revenues from its sale. Any of these events could further have other material and adverse effects on our operations and business
and could adversely impact our stock price and could significantly harm our business, financial condition, results of operations, and prospects.

The  FDA’s  policies  may  change  and  additional  government  laws  and  regulations  may  be  enacted  that  could  prevent,  limit,  or  delay  regulatory
approval of our product candidates, that could limit the marketability of our product candidates, or that could impose additional regulatory obligations on
us. By example the change in the U.S. administration that occurred on January 20, 2021 may result in new or revised laws, regulatory requirements, and
associated compliance obligations, as well as postponed or frozen regulatory requirements.  Changes in medical practice and standard of care may also
impact the marketability of our product candidates. If we are slow or unable to adapt to changes in existing requirements, standards of care, or the adoption
of new requirements or policies, or if we are not able to maintain regulatory compliance, we may lose any marketing approval that we may have obtained
and be subject to regulatory enforcement action.

Should any of the above actions take place, they could adversely affect our ability to achieve or sustain profitability. Further, the cost of compliance

with post-approval regulations may have a negative effect on our operating results and financial condition.

If we fail to comply with foreign, federal, state, and local healthcare laws, including fraud and abuse and health information privacy and security laws,
we could face substantial penalties and our business, results of operations, financial condition and prospects could be adversely affected.

As a biotechnology company, even though we do not provide healthcare services or receive payments directly from or bill directly to Medicare,
Medicaid, or other third-party payors for our products, certain federal, state, local and foreign healthcare laws and regulations pertaining to fraud and abuse
and  patients’  rights  are  applicable  to  our  business.  We  are  subject  to  healthcare  fraud  and  abuse  and  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 makes it illegal for any person or entity, including a prescription drug manufacturer (or a party acting on
its behalf) to knowingly and willfully solicit, receive, offer or pay remuneration, directly or indirectly, overtly or covertly, to induce, or in
return for, either the referral of an individual, or the purchase, lease, prescribing or recommendation of an item, good, facility or service
reimbursable by a federally funded healthcare program, such as the Medicare or Medicaid program. The term “remuneration” has been
interpreted  broadly  and  may  constrain  our  marketing  practices,  educational  programs,  pricing  policies  and  relationships  with  healthcare
providers or other entities, among other activities;

federal civil and criminal false claims, including the federal False Claims Act, and false statement laws and civil monetary penalty laws,
which impose criminal and civil penalties, including through civil whistleblower or qui tam actions, on individuals or entities for, among
other things, knowingly presenting, or causing to be presented, claims for payment or approval from Medicare, Medicaid or other federal
health care programs that are false or fraudulent or knowingly making any materially false statement in connection with the delivery or
payment for healthcare benefits, items or services;

the U.S. federal Health Insurance Portability and Accountability Act of 1996, as amended, or HIPAA, which imposes criminal and civil
liability for, among other things, knowingly and willfully executing, or attempting to execute, a scheme to defraud any healthcare benefit
program  or  obtain,  by  means  of  false  or  fraudulent  pretenses,  representations,  or  promises,  any  of  the  money  or  property  owned  by,  or
under  the  custody  or  control  of,  any  healthcare  benefit  program,  regardless  of  the  payor  (e.g.,  public  or  private)  and  knowingly  and
willfully  falsifying,  concealing  or  covering  up  by  any  trick  or  device  a  material  fact  or  making  any  materially  false  statement,  in
connection with the delivery of, or payment for, healthcare benefits, items or services. Similar to the U.S. 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;

HIPAA,  as  amended  by  the  Health  Information  Technology  for  Economic  and  Clinical  Health,  or  HITECH,  and  their  respective
implementing regulations mandates, among other things, the adoption of uniform standards for the electronic exchange of information in
common healthcare transactions, as well as standards relating to the privacy, security and transmission of individually identifiable health
information,  which  require  the  adoption  of  administrative,  physical  and  technical  safeguards  to  protect  such  information.  Among  other
things,  HITECH  makes  HIPAA's  security  standards  directly  applicable  to  "business  associates",  or  independent  contractors  or  agents  of
covered  entities  that  create,  receive  or  obtain  protected  health  information  in  connection  with  providing  a  service  for  or  on  behalf  of  a
covered entity;

the Physician Payments Sunshine Act and its implementing regulations, which requires certain manufacturers of drugs, biologics, medical
devices  and  medical  supplies  for  which  payment  is  available  under  Medicare,  Medicaid  or  the  CMS,  certain  payments  and  transfers  of
value  made  to  physicians  and  teaching  hospitals,  and  ownership  or  investment  interests  held  by  physicians  and  their  immediate  family
members.  Beginning  in  2022,  applicable  manufacturers  will  also  be  required  to  report  information  regarding  payments  and  transfers  of
value  provided  to  physician  assistants,  nurse  practitioners,  clinical  nurse  specialists,  certified  nurse  anesthetists,  and  certified  nurse-
midwives; and,

40

 
 
 
 
 
 
•

state law equivalents of each of the above federal laws, such as anti-kickback and false claims laws, which may apply to items or services
reimbursed by any third-party payor, including commercial insurers; state and foreign laws governing 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  effect,  thus
complicating compliance efforts; state, local and foreign 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,  obtain
pharmaceutical agent licensure, and/or otherwise restrict payments that may be made to healthcare providers and entities; and state, local
and foreign laws and industry codes that require drug manufacturers to report information related to payments and other transfers of value
to healthcare providers or entities, or marketing expenditures.

Because  of  the  breadth  of  these  laws  and  the  narrowness  of  the  statutory  exceptions  and  safe  harbors  available  under  the  U.S.  federal  Anti-
Kickback Statute, it is possible that some of our business activities could be subject to challenge under one or more of such laws. Moreover, recent health
care  reform  legislation  has  strengthened  these  laws.  For  example,  the  ACA,  among  other  things,  amends  the  intent  requirement  of  the  federal  Anti-
Kickback Statute and criminal health care fraud statutes, so that a person or entity no longer needs to have actual knowledge of the statute or specific intent
to violate it. In addition, the ACA provides that 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.

Recently, several pharmaceutical and other healthcare companies have been prosecuted under the federal false claims laws for allegedly inflating
drug prices they report to pricing services, which in turn are used by the government to set Medicare and Medicaid reimbursement rates, and for allegedly
providing  free  product  to  customers  with  the  expectation  that  the  customers  would  bill  federal  programs  for  the  product.  In  addition,  certain  marketing
practices, including off-label promotion, interactions with specialty pharmacies, and patient assistance programs may also violate fraud and abuse laws. To
the extent that any product we make is sold in a foreign country, we may be subject to similar foreign laws and regulations.

In addition, certain state and local laws mandate that we comply with a state code of conduct, adopt a company code of conduct under state criteria,
disclose marketing payments made to health care professionals and entities, disclose drug pricing information and/or report compliance information to the
state  authorities.  The  shifting  compliance  environment  and  the  need  to  build  and  maintain  robust  and  expandable  systems  to  comply  in  multiple
jurisdictions with different compliance and reporting requirements increase the possibility that a pharmaceutical company may violate one or more of the
requirements. Any failure to comply with these reporting requirements could result in significant fines and penalties.

The risks of complying with these laws cannot be entirely eliminated. The risk of violation of such laws is also increased because many of them
have not been fully interpreted by the regulatory authorities or the courts, and their provisions are open to a variety of interpretations. Any action against us
for  violation  of  these  laws,  even  if  we  successfully  defend  against  it,  could  cause  us  to  incur  significant  legal  expenses  and  divert  our  management’s
attention  from  the  operation  of  our  business.  Moreover,  achieving  and  sustaining  compliance  with  applicable  federal,  state,  local  and  foreign  privacy,
security, fraud and transparency laws may prove costly. If our past or present operations, or those of our distributors 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  sanctions,  including  civil  and  administrative
penalties,  criminal  fines,  damages,  disgorgement,  exclusion  from  participation  in  U.S.  federal  or  state  health  care  programs,  individual  imprisonment,
integrity  obligations,  and  the  curtailment  or  restructuring  of  our  operations,  any  of  which  could  materially  adversely  affect  our  ability  to  operate  our
business  and  our  financial  results.  Similarly,  if  healthcare  providers,  distributors  or  other  entities  with  whom  we  do  business  are  found  to  be  out  of
compliance with applicable laws and regulations, they may be subject to sanctions, which could also have a negative impact on us.

Our  employees,  independent  contractors,  consultants,  commercial  partners,  principal  investigators,  or  CROs  may  engage  in  misconduct  or  other
improper activities, including noncompliance with regulatory standards and requirements, which could have a material adverse effect on our business.

We are exposed to the risk of employee fraud or other misconduct. Misconduct by employees, independent contractors, consultants, commercial
partners, manufacturers, investigators, or CROs could include intentional, reckless, negligent, or unintentional failures to comply with FDA regulations or
applicable fraud and abuse laws,

41

 
 
provide accurate information to the FDA, properly calculate pricing information required by federal programs, comply with federal procurement rules or
contract terms, report financial information or data accurately or disclose unauthorized activities to us. This misconduct could also involve the improper use
or misrepresentation of information obtained in the course of clinical trials, which could result in regulatory sanctions and serious harm to our reputation. It
is not always possible to identify and deter this type of misconduct, and the precautions we take to detect and prevent this activity may not be effective in
controlling  unknown  or  unmanaged  risks  or  losses  or  in  protecting  us  from  governmental  investigations  or  other  actions  or  lawsuits  stemming  from  a
failure to be in compliance with such laws or regulations. Moreover, it is possible for a whistleblower to pursue a False Claims Act case against us even if
the government considers the claim unmeritorious and declines to intervene, which could require us to incur costs defending against such a claim. Further,
due to the risk that a judgment in a False Claims Act case could result in exclusion from federal health programs or debarment from government contracts,
whistleblower  cases  often  result  in  large  settlements.  If  any  such  actions  are  instituted  against  us,  and  we  are  not  successful  in  defending  ourselves  or
asserting our rights, those actions could have a significant impact on our business, financial condition, and results of operations, including the imposition of
significant fines or other sanctions.

Our  operations,  including  our  use  of  hazardous  materials,  chemicals,  bacteria,  and  viruses,  require  us  to  comply  with  regulatory  requirements  and
expose us to significant potential liabilities.

Our operations involve the use of hazardous materials, including chemicals, and may produce dangerous waste products. Accordingly, we, along
with the third parties that conduct clinical trials and manufacture our products and product candidates on our behalf, are subject to federal, state, local and
foreign laws and regulations that govern the use, manufacture, distribution, storage, handling, exposure, disposal and recordkeeping with respect to these
materials.  We  are  also  subject  to  a  variety  of  environmental  and  occupational  health  and  safety  laws.  Compliance  with  current  or  future  laws  and
regulations can require significant costs and we could be subject to substantial fines and penalties in the event of noncompliance. In addition, the risk of
contamination or injury from these materials cannot be completely eliminated. In such event, we could be held liable for substantial civil damages or costs
associated with the cleanup of hazardous materials.

Intellectual Property Risks

If we are unable to protect our intellectual proprietary rights, our business could be harmed.

Our commercial success will depend, in large part, on our ability to obtain and maintain protection in the United States and other countries for the
intellectual  property  covering  or  incorporated  into  our  technology,  products  and  product  candidates.  Obtaining  and  maintaining  this  protection  is  very
costly.  The  patentability  of  technology  in  the  biotechnology  field  generally  is  highly  uncertain  and  involves  complex  legal  and  scientific  questions.  We
cannot  be  certain  that  our  patents  and  patent  applications,  including  our  own  and  those  that  we  have  rights  through  licenses  from  third  parties,  will
adequately protect our intellectual property. Our success protecting our intellectual property depends significantly on our ability to:

•

•

•

•

•

obtain and maintain U.S. and foreign patents, that are meaningful to our products, including defending those patents against adverse claims;

secure patent term extension for the patents covering our approved products;

protect trade secrets;

operate without infringing the proprietary rights of others; and,

prevent others from infringing our proprietary rights.

We may not be able to obtain issued patents relating to our technology or product candidates. Even if issued, patents may inadvertently lapse or be
challenged, narrowed, invalidated, or circumvented, which could limit our ability to stop competitors from marketing similar products or limit the duration
of patent protection we may have for our product candidates. Further, patents may lapse prior to the regulatory approval of the underlying product in one or
more territories. In the past, we have abandoned the prosecution and/or maintenance of patent applications related to patent families in the ordinary course
of business. In the future, we may choose to abandon such prosecution and/or maintenance in a similar fashion. If these patent rights are later determined to
be valuable or necessary to our business, our competitive position may be adversely affected. Changes in patent laws or

42

 
 
 
 
 
 
administrative patent office rules or changes in interpretations of patent laws in the United States and in other countries may diminish the value of our
intellectual property or narrow the scope of our patent protection, or result in costly defensive measures.

Patent  and  other  intellectual  property  laws  outside  the  United  States  are  even  more  uncertain  than  in  the  United  States  and  are  continually
undergoing review and revisions in many countries. Further, the laws of some foreign countries may not protect our intellectual property rights to the same
extent as the laws of the United States. For example, certain countries do not grant patent claims that are directed to business methods and processes. In
addition, we may have to participate in additional opposition proceedings, like the proceedings described above, to determine the validity of our foreign
patents or our competitors’ foreign patents, which could result in substantial costs and diversion of our efforts.

Our collaborative partners and licensors may not adequately protect our intellectual property rights. These third parties may have the first right to
maintain or defend intellectual property rights in which we have an interest and, although we may have the right to assume the maintenance and defense of
such intellectual property rights if these third parties do not do so, our ability to maintain and defend such intellectual property rights may be compromised
by the acts or omissions of these third parties.

The cost of litigation to uphold the validity of patents, once obtained, to prevent infringement or to otherwise protect or enforce our proprietary
rights  could  be  substantial  and,  from  time  to  time,  our  patents  are  subject  to  patent  office  proceedings.  Some  of  our  competitors  may  be  better  able  to
sustain the costs of complex patent litigation because they may have substantially greater financial resources. Intellectual property lawsuits are expensive
and unpredictable and would consume management’s time and attention and other resources, even if the outcome were successful. In addition, there is a
risk that a court would decide that our patents are not valid and that we do not have the right to stop the other party from using the inventions covered by or
incorporating  them.  There  is  also  a  risk  that,  even  if  the  validity  of  a  patent  were  upheld,  a  court  would  refuse  to  stop  the  other  party  from  using  the
invention(s), including on the grounds that its activities do not infringe the patent. If any of these events were to occur, our business, financial condition and
operating results could be materially and adversely affected.

In addition to patent litigation, we may be a party to adversarial proceedings before the Patent Trial and Appeal Board (PTAB) of the US Patent and
Trademark Office (USPTO), or the Opposition Division of the European Patent Office (EPO). Potential proceedings before the PTAB include inter partes
review proceedings, post-grant review proceedings and interference proceedings. Depending on our level of success at the PTAB and Opposition Division
of the EPO, these proceedings could adversely impact our intellectual property rights with respect to our products and technology.

In addition, the U.S. Supreme Court has ruled on several patent cases in recent years, either narrowing the scope of patent protection available in
certain circumstances or weakening the rights of patent owners in certain situations. This combination of events has created uncertainty with respect to the
value of patents, once obtained, and with regard to our ability to obtain patents in the future. Depending on decisions by the U.S. Congress, the federal
courts, and the USPTO, the laws and regulations governing patents could change in unpredictable ways that would weaken our ability to obtain new patents
or to enforce our existing patents and patents that we might obtain in the future. Patent and intellectual property laws outside of the United States may also
change and be uncertain.

Our  patents,  once  obtained,  also  may  not  afford  us  protection  against  competitors  with  similar  technology.  Because  patent  applications  in  the
United  States  and  many  foreign  jurisdictions  are  typically  not  published  until  eighteen  months  after  filing,  or  in  some  cases  not  at  all,  and  because
publications of discoveries in the scientific literature often lag behind actual discoveries, neither we nor our licensors can be certain that others have not
filed  or  maintained  patent  applications  for  technology  used  by  us  or  covered  by  our  pending  patent  applications  without  our  being  aware  of  these
applications.

We also will rely on current and future trademarks to establish and maintain recognized brands, including APTEVO THERAPEUTICS, APTEVO
BIOTHERAPEUTICS, APTEVO RESEARCH AND DEVELOPMENT, the Aptevo logo, ADAPTIR, and ADAPTIR-FLEX in relevant jurisdictions. If we
fail to acquire and protect such trademarks, our ability to market and sell our products, if approved for marketing, will be harmed. In addition, our current
and future trademarks may be challenged, infringed, circumvented, declared generic, lapsed or determined to be infringing on or dilutive of other marks
and we may not be able to protect our rights in these trademarks, which we need in order to build name recognition. Any of the foregoing cold have a
material and adverse effect on our business, financial condition and operating results.  

43

 
Third parties may choose to file patent infringement claims against us.

Our development and commercialization activities, as well as any product candidates or products resulting from these activities, may infringe or be
claimed to infringe patents and other intellectual property rights of third parties under which we do not hold sufficient licenses or other rights. Third parties
may  be  successful  in  obtaining  patent  protection  for  technologies  that  cover  development  and  commercialization  activities  in  which  we  are  already
engaged.  These  third  parties  may  have  substantially  greater  financial  resources  than  us  and  could  bring  claims  against  us  that  could  cause  us  to  incur
substantial expenses to defend against these claims and, if successful against us, could cause us to pay substantial damages. If a patent infringement or
other similar suit were brought against us, we could be forced to stop or delay development, manufacturing or sales of the product or product candidate that
is the subject of the suit. Intellectual property litigation in the biotechnology industry is common, and we expect this trend to continue.

As a result of patent infringement or other similar claims, or to avoid potential claims, we may choose or be required to seek a license from the
third party and be required to pay license fees or royalties or both. These licenses may not be available on acceptable terms, or at all. Even if we were able
to obtain a license, the rights may be non-exclusive, which could result in our competitors gaining access to the same intellectual property. 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 acceptable terms, if at all, or if an injunction is granted against us, which could harm our
business significantly.

There  has  been  substantial  litigation  and  other  proceedings  regarding  patent  and  other  intellectual  property  rights  in  the  pharmaceutical  and
biotechnology industries. In addition to infringement claims against us, we may become a party to other patent litigation and other adversarial proceedings
such as proceedings before the Patent Trial Appeals Board and opposition proceedings in the European Patent Office, regarding intellectual property rights
that could impact our products and technology.

Patent litigation and other proceedings may also absorb significant management time. The cost to us of any patent litigation or other proceeding,
even  if  resolved  in  our  favor,  could  be  substantial.  Some  of  our  competitors  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 have a material adverse effect on our ability to compete in the marketplace. Patent litigation and other proceedings
may also absorb significant management time.

Our Aptevo trademarks may be opposed which could have a material and adverse effect on our business.

We  have  applications  pending  that  cover  the  APTEVO  THERAPEUTICS,  APTEVO  BIOTHERAPEUTICS,  and  APTEVO  RESEARCH  AND
DEVELOPMENT trademarks. We refer to these trademarks as our house marks. If a third party opposes any of these house marks and we are unable to
reach settlement prior to the commencement of an opposition proceeding, we may incur significant expense in the course of participating in the opposition
process, which can be expensive and lengthy. Any settlement with a third party may result in our agreeing to be subject to restrictions on our use of the
relevant house mark. In addition, if we are unsuccessful in an opposition against a house mark, we would lose the ability to obtain trademark registration
for one or more uses of the relevant mark both in the United States and in other territories which could have a material and adverse effect on our business.

We may be subject to claims that our employees have wrongfully used or disclosed alleged trade secrets of their former employers.

As is common in the biotechnology and pharmaceutical industry, we employ individuals who were previously employed at other biotechnology or
pharmaceutical companies, including our competitors or potential competitors. We may be subject to claims that these employees or we have inadvertently
or otherwise used or disclosed trade secrets or other proprietary information of their former employers. Litigation may be necessary to defend against these
claims. Even if we are successful in defending against these claims, litigation could result in substantial costs and be a distraction to management.

44

 
Failure to comply with our obligations in our intellectual property licenses with third parties, could result in loss of license rights or other damages.

We are a party to a number of license agreements and expect to enter into additional license agreements in the future. Our existing licenses impose,
and we expect future licenses will impose, various diligence, milestone payment, royalty, insurance, and other obligations on us. If we fail to comply with
these obligations, the licensor may have the right to terminate the license in whole or in part, terminate the exclusive nature of the license and/or sue us for
breach, which could cause us to not be able to market any product that is covered by the licensed patents and may be subject to damages.

If we are unable to protect the confidentiality of our proprietary information and know-how, the value of our technology and product candidates could
be adversely affected.

In addition to patented technology, we rely upon unpatented proprietary technology, information processes and know-how. These types of trade
secrets can be difficult to protect. We seek to protect this confidential information, in part, through agreements with our employees, consultants and third
parties  as  well  as  confidentiality  policies  and  audits,  although  these  may  not  be  successful  in  protecting  our  trade  secrets  and  confidential  information.
These agreements may be breached, and we may not have adequate remedies for any such breach. In addition, our trade secrets may otherwise become
known,  including  through  a  potential  cyber  security  breach,  or  may  be  independently  developed  by  competitors.  If  we  are  unable  to  protect  the
confidentiality of our proprietary information and know-how, competitors may be able to use this information to develop products that compete with our
products, which could adversely impact our business.

Risk Related to Collaborations and Other Agreements

We may not be successful in establishing and maintaining collaborations that leverage our capabilities in pursuit of developing and commercializing
our product candidates.

For each of our product candidates we plan to evaluate the merits of entering into collaboration arrangements with third parties, including leading
biotechnology companies or non-governmental organizations. In July 2017, we entered into a collaboration agreement with Alligator pursuant to which
Aptevo R&D and Alligator will collaboratively develop ALG.APV-527, a lead bispecific antibody candidate simultaneously targeting 4-1BB (CD137), a
member of the TNFR superfamily of a costimulatory receptor found on activated T-cells, and 5T4, a tumor antigen widely overexpressed in a number of
different types of cancer. We intend to pursue collaboration arrangements with third parties that have particular technology, expertise or resources for the
development or commercialization of our product candidates or for accessing particular markets. We face, and will continue to face, significant competition
in seeking appropriate partners for our product candidates. If we are unable to identify partners whose capabilities complement and integrate well with ours
and  reach  collaboration  arrangements  with  such  partners  on  a  timely  basis,  on  acceptable  terms  or  at  all,  or  if  the  arrangements  we  establish  are
unproductive  for  us,  we  may  fail  to  meet  our  business  objectives  for  the  particular  product  candidate.  Our  ability  to  enter  into  such  arrangements  with
respect to products in development that are subject to licenses may be limited by the terms of those licenses.

Our collaboration agreement with Alligator, or any collaboration agreement we may consider entering into, may not be successful and the success
of our collaboration arrangements will depend heavily on the efforts and activities of our collaborative partners. It is likely that our collaborative partners
will have significant discretion in determining the efforts and resources that they will apply to these collaborations.

The risks that we are subject to in any of our collaborations include, among others:

•

•

•

•

our  collaborative  partners  may  not  commit  adequate  resources  to  the  development,  marketing  and  distribution  of  any  collaboration
products, limiting our potential revenues from these products;

our collaborative partners may experience financial difficulties and may therefore be unable to meet their commitments to us;

our  collaborative  partners  may  pursue  a  competing  product  candidate  developed  either  independently  or  in  collaboration  with  others,
including our competitors; and,

our collaborative partners may terminate our relationship.

45

 
 
 
 
 
The failure of any of our current or future collaboration partners to perform as expected could place us at a competitive disadvantage and adversely
affect us financially, including delay and increased costs of development, loss of market opportunities, lower than expected revenues and impairment of the
value  of  the  related  product  candidate.  A  loss  of  our  collaboration  agreement  with  Alligator  would  result  in  a  burden  of  locating  a  replacement  partner
under  potentially  less  favorable  terms  at  an  additional  cost.  Collaborations  are  a  critical  part  of  our  business  strategy,  and  any  inability  on  our  part  to
establish  and  successfully  maintain  such  arrangements  on  terms  favorable  to  us  or  to  work  successfully  with  our  collaborative  partners  could  have  an
adverse  effect  on  our  operations  and  financial  performance.  Due  to  COVID-19,  we  may  experience  delays  in  opportunities  to  develop  our  product
candidates, due to financial and other impacts on potential partners.

In  connection  with  our  separation  from  Emergent,  we  and  Emergent  agreed  to  indemnify  the  other  party  for  certain  liabilities.  The  Emergent
indemnity  may  not  be  sufficient  to  hold  us  harmless  from  the  full  amount  of  liabilities  for  which  Emergent  will  be  allocated  responsibility,  and
Emergent may not be able to satisfy its indemnification obligations in the future.

Pursuant to the separation agreement and certain other agreements with Emergent, Emergent has agreed to indemnify us for certain liabilities, and
we  agreed  to  indemnify  Emergent  for  certain  liabilities.  Indemnities  that  we  may  be  required  to  provide  Emergent  are  not  subject  to  any  cap,  may  be
significant  and  could  negatively  impact  our  business,  particularly  indemnities  relating  to  our  actions  that  could  impact  the  tax-free  nature  of  the
distribution. Third parties could also seek to hold us responsible for any of the liabilities that Emergent has agreed to retain. Any amounts we are required
to pay pursuant to these indemnification obligations and other liabilities could require us to divert cash that would otherwise have been used in furtherance
of our operating business. Further, the indemnity from Emergent may not be sufficient to protect us against the full amount of such liabilities, and Emergent
may not be able to fully satisfy its indemnification obligations. Moreover, even if we ultimately succeed in recovering from Emergent any amounts for
which we are held liable, we may be temporarily required to bear these losses ourselves. Each of these risks could negatively affect our business, results of
operations and financial condition.

Risks Related to Our Common Stock and General Risks

Our stock price may be volatile.

Our stock price has fluctuated in the past and is likely to be volatile in the future. Since August 1, 2016, the reported closing price of our common
stock has fluctuated between $3.29 and $112 per share (as adjusted to reflect our 1-for-14 reverse stock split of our outstanding common stock that was
effective on March 26, 2020). The stock market in general, and the market for biotechnology companies in particular, have experienced extreme volatility
that has often been unrelated to the operating performance of particular companies. In particular, the stock market has experienced extreme volatility in
recent months as a result of COVID-19 and its impact on the global economy. The market price of our common stock may fluctuate significantly due to a
number of factors, some of which may be beyond our control or unrelated to our operations, including, among others:

•

•

•

•

•

•

•

•

•

•

changes in earnings estimated by securities analysts or management, or our ability to meet those estimates;

the resolution of the Tang Stockholder Proposals;

investor perceptions or negative announcements by our competitors, suppliers, or partners regarding their own performance;

the success of competitive products or technologies;

the timing, expenses, and results of clinical and non-clinical trials of our product candidates;

announcements regarding clinical trial results and product introductions by us or our competitors;

announcements of acquisitions, collaborations, financings or other transactions by us or our competitors;

public concern as to the safety of our product candidates;

termination or delay of a development program;

the recruitment or departure of key personnel;

46

 
 
 
 
 
 
 
 
 
 
 
 
•

•

•

•

•

•

•

estimated or actual sales of IXINITY by Medexus;

whether and to what extent future proceeds are received under our royalty purchase agreement with HCR;

actual or anticipated variations in our cash flows or results of operations;

the operating and stock price performance of comparable companies;

the impact of COVID-19 or similar global health challenges;

general industry conditions and domestic and global financial, economic, and geo-political instability; and,

the other factors described in this “Risk Factors” section.

Biotechnology  company  stock  prices  have  declined  significantly  in  certain  instances  where  companies  have  failed  to  obtain  FDA  or  foreign
regulatory authority approval of a product candidate or if the timing of FDA or foreign regulatory authority approval is delayed. If the FDAs or any foreign
regulatory authority’s response to any application for approval is delayed or not favorable for any of our product candidates, our stock price could decline
significantly.

In addition, when the market price of a company’s common stock drops significantly, stockholders often institute securities class action lawsuits
against the company. A lawsuit against us could cause us to incur substantial costs and could divert the time and attention of our management and other
resources.

In the event that coverage under our directors’ and officers’ liability insurance is reduced or terminated as a result of the Tang Ownership Change or
otherwise, our indemnification obligations and limitations of our directors’ and officers’ liability insurance may have a material adverse effect on our
financial condition, results of operations and cash flows.

Under Delaware law, our certificate of incorporation, and our bylaws and certain indemnification agreements to which we are a party, we have an
obligation to indemnify, or we have otherwise agreed to indemnify, certain of our current and former directors and officers with respect to past, current, and
future  investigations  and  litigation.  In  order  to  reduce  the  risk  of  expense  of  these  obligations,  we  maintain  directors’  and  officers’  liability  insurance.
However, as a result of the Tang Ownership Change, the cost to us of our directors’ and officers’ liability insurance coverage has increased, and it may
continue to increase in the future, or the coverage thereunder may be reduced or terminated in full. In the event that the coverage under our directors’ and
officers’ liability insurance is reduced or terminated, we will be required to pay the expenses of indemnifying our current and former directors and officers
in  their  defense  of  current  and  future  investigations  and  litigation,  which  expenses  may  be  significant.  The  increased  costs  to  us  of  our  directors’  and
officers’ liability insurance coverage, or our indemnification obligations if our directors’ and officers’ liability insurance coverage is reduced or terminated,
could result in the diversion of our financial resources, and may have a material adverse effect on our financial condition, results of operations and cash
flows.

If we do not maintain effective internal controls, we may not be able to accurately report our financial results and our business could be harmed.

The Sarbanes-Oxley Act requires, among other things, that we assess the effectiveness of our internal control over financial reporting annually and
the effectiveness of our disclosure controls and procedures quarterly. In particular, Section 404 of the Sarbanes-Oxley Act, or Section 404, requires us to
perform system and process evaluation and testing of our internal control over financial reporting to allow management to report on, and our independent
registered public accounting firm potentially to attest to, the effectiveness of our internal control over financial reporting. As an emerging growth company,
we have availed ourselves of the exemption from the requirement that our independent registered public accounting firm attest to the effectiveness of our
internal control over financial reporting under Section 404. However, we may no longer avail ourselves of this exemption when we cease to be an emerging
growth  company.  When  our  independent  registered  public  accounting  firm  is  required  to  undertake  an  assessment  of  our  internal  control  over  financial
reporting,  the  cost  of  our  compliance  with  Section  404  will  correspondingly  increase.  Our  compliance  with  applicable  provisions  of  Section  404  will
require that we incur substantial accounting expense and expend significant management time on compliance-related issues as we

47

 
 
 
 
 
 
 
 
 
implement  additional  corporate  governance  practices  and  comply  with  reporting  requirements.  Moreover,  if  we  are  not  able  to  comply  with  the
requirements of Section 404 applicable to us in a timely manner, or if we or our independent registered public accounting firm identifies deficiencies in our
internal control over financial reporting that are deemed to be material weaknesses, the market price of our stock could decline and we could be subject to
sanctions or investigations by the SEC or other regulatory authorities, which would require additional financial and management resources.

Investor  perceptions  of  our  company  may  suffer  if  material  weaknesses  are  found,  and  this  could  cause  a  decline  in  the  market  price  of  our
common stock. Irrespective of compliance with Section 404, any failure of our internal control over financial reporting could harm our operating results
and reputation. If we are unable to implement these requirements effectively or efficiently, it could harm our operations, financial reporting, or financial
results and could result in an adverse opinion on our internal controls from our independent registered public accounting firm.

The public announcement of data from clinical trials or news of any developments related to our product pipeline may cause significant volatility in
our stock price.

The announcement of data from clinical trials by us or our collaborative partners or news of any developments related to our key pipeline product
candidates may cause significant volatility in our stock price. Furthermore, the announcement of any negative or unexpected data or the discontinuation of
development of any of our key pipeline product candidates, or any delay in our anticipated timelines for filing for regulatory approval, could cause our
stock price to decline significantly. There can be no assurance that data from clinical trials will support a filing for regulatory approval or even if approved,
that any of our key pipeline products will become commercially successful.

Our  common  stock  may  be  at  risk  for  delisting  from  the  Nasdaq  Capital  Market  in  the  future.  Delisting  could  adversely  affect  the  liquidity  of  our
common stock and the market price of our common stock could decrease.

Our common stock is currently listed on the Nasdaq Capital Market. The Nasdaq Stock Market LLC has minimum requirements that a company
must meet in order to remain listed on Nasdaq, including corporate governance standards and a requirement that we maintain a minimum closing bid price
of  $1.00  per  share.    If  we  fail  to  maintain  such  minimum  requirements  and  a  final  determination  is  made  by  Nasdaq  that  our  common  stock  must  be
delisted, the liquidity of our common stock would be adversely affected and the market price of our common stock could decrease. In addition, if delisted,
we would no longer be subject to Nasdaq rules, including rules requiring us to have a certain number of independent directors and to meet other corporate
governance standards. Our failure to be listed on Nasdaq or another established securities market would have a material adverse effect on the value of your
investment in us.

If our common stock is not listed on Nasdaq or another national exchange, the trading price of our common stock is below $5.00 per share and we
have net tangible assets of $6,000,000 or less, the open-market trading of our common stock will be subject to the “penny stock” rules promulgated under
the Securities Exchange Act of 1934, as amended. If our shares become subject to the “penny stock” rules, broker-dealers may find it difficult to effectuate
customer transactions and trading activity in our securities may be adversely affected. Under these rules, broker-dealers who recommend such securities to
persons other than institutional accredited investors must:

•

•

•

•

make a special written suitability determination for the purchaser;

receive the purchaser’s written agreement to the transaction prior to sale;

provide the purchaser with risk disclosure documents which identify certain risks associated with investing in “penny stocks” and which
describe the market for these “penny stocks” as well as a purchaser’s legal remedies; and

obtain  a  signed  and  dated  acknowledgment  from  the  purchaser  demonstrating  that  the  purchaser  has  actually  received  the  required  risk
disclosure document before a transaction in a “penny stock” can be completed.

As a result of these requirements, the market price of our securities may be adversely impacted, and current stockholders may find it more difficult

to sell our securities.

Your percentage of ownership in Aptevo may be diluted in the future.

In  the  future,  your  percentage  ownership  in  Aptevo  may  be  diluted  because  of  equity  issuances  for  acquisitions,  capital  market  transactions  or
otherwise, including, but not limited to, equity issuances under our existing equity sales agreement with Lincoln Park Financial LLC, under our Equity
Distribution Agreement with Piper Sandler, under our Rights Plan with Broadridge Corporate Issuer Solutions, Inc., upon the exercise of warrants issued in
connection  with  our  March  2019  public  offering,  and  equity  awards  to  our  directors,  officers  and  employees.  Our  employees  have  options  to  purchase
shares  of  our  common  stock  and  from  time  to  time,  we  expect  to  issue  additional  options,  restricted  stock  units,  or  other  stock-based  awards  to  our
employees under our employee benefits plans.

In addition, our restated certificate of incorporation authorizes us to issue, without the approval of our stockholders, one or more classes or series of
preferred stock having such designation, powers, preferences and relative, participating, optional and other special rights, including preferences over our
common stock respecting dividends and distributions, as our board of directors generally may determine. The terms of one or more classes or series of
preferred stock could dilute the voting power or reduce the value of our common stock. For example, we could grant the holders of preferred stock the right
to  elect  some  number  of  our  directors  in  all  events  or  on  the  happening  of  specified  events  or  the  right  to  veto  specified  transactions.  Similarly,  the
repurchase  or  redemption  rights  or  liquidation  preferences  we  could  assign  to  holders  of  preferred  stock  could  affect  the  residual  value  of  the  common
stock.

Provisions under Delaware law and in our restated certificate of incorporation, amended and restated by-laws and rights agreement may discourage
acquisition proposals, delay a change in control or prevent transactions that stockholders may consider favorable.

Certain provisions in our restated certificate of incorporation and amended and restated by-laws, and under Delaware law, may discourage, delay,
or prevent a merger, acquisition or other changes in control that stockholders may consider favorable, including transactions in which stockholders might
otherwise  receive  a  premium  for  their  shares.  These  provisions  may  also  prevent  or  frustrate  attempts  by  our  stockholders  to  replace  or  remove  our
incumbent directors and management.

These provisions include:

•

•

•

•

•

•

•

the classification of our directors;

limitations on the removal of directors;

limitations on filling vacancies on the board;

advance notice requirements for stockholder nominations of candidates for election to the Board of Directors and other proposals;

the inability of stockholders to act by written consent;

the inability of stockholders to call special meetings; and,

the ability of our Board of Directors to designate the terms of and issue a new series of preferred stock without stockholder approval.

The affirmative vote of holders of our capital stock representing at least 75% of the voting power of all outstanding stock entitled to vote is required
to amend or repeal the above provisions of our certificate of incorporation. The affirmative vote of either a majority of the directors present at a meeting of
our Board of Directors or holders of our capital stock representing at least 75% of the voting power of all outstanding stock entitled to vote is required to
amend or repeal our by-laws.

In  addition,  Section  203  of  the  General  Corporation  Law  of  Delaware  prohibits  a  corporation  from  engaging  in  a  business  combination  with  an
interested stockholder, generally a person which, together with its affiliates, owns or within the last three years has owned 15% or more of the corporation’s
voting  stock,  for  a  period  of  three  years  after  the  date  of  the  transaction  in  which  the  person  became  an  interested  stockholder,  unless  the  business
combination is approved in a prescribed manner. Accordingly, Section 203 may discourage, delay or prevent a change in control of us. Tang is an interested
stockholder for purposes of Section 203.

49

 
 
 
 
 
 
 
 
Moreover, in November 2020 our Board adopted a short-term stockholder rights agreement with an expiration date of November 8, 2021. This rights
agreement could render more difficult, or discourage a merger, tender offer, or assumption of control of the Company that is not approved by our Board that
some stockholders may consider favorable. The rights agreement, however, should not interfere with any merger, tender or exchange offer or other business
combination approved by our Board. Nor does the rights agreement prevent our Board from considering any offer that it considers to be in the best interest
of our stockholders.

Our bylaws include a forum selection clause, which may impact your ability to bring actions against us.

Subject to certain limitations, our bylaws provide that, unless we consent in writing to the selection of an alternative forum, the Court of Chancery
in  the  State  of  Delaware  will  be  the  sole  and  exclusive  forum  for  any  stockholder  (including  a  beneficial  owner)  to  bring:  (a)  any  derivative  action  or
proceeding brought on our behalf; (b) any action asserting a claim of breach of fiduciary duty owed by any of our directors, officers or other employees or
our stockholders; (c) any action asserting a claim arising pursuant to any provision of the DGCL or our certificate of incorporation or bylaws; or (d) any
action asserting a claim governed by the internal affairs doctrine. In addition, our bylaws provide that unless we consent in writing to the selection of an
alternative forum, the federal district courts of the United States will be the exclusive forum for resolving any complaint asserting a cause of action arising
under the federal securities laws of the United States against us, our officers, directors, employees or underwriters. These limitations on the forum in which
stockholders may initiate action against us could create costs, inconvenience or otherwise adversely affect your ability to seek legal redress.

Section 22 of the Securities Act creates concurrent jurisdiction for federal and state courts over all suits brought to enforce any duty or liability
created by the Securities Act or the rules and regulations thereunder. As a result, a court may decline to enforce these exclusive forum provisions with
respect  to  suits  brought  to  enforce  any  duty  or  liability  created  by  the  Securities  Act  or  any  other  claim  for  which  the  federal  and  state  courts  have
concurrent  jurisdiction,  and  our  stockholders  may  not  be  deemed  to  have  waived  our  compliance  with  the  federal  securities  laws  and  the  rules  and
regulations thereunder. If a court were to find the exclusive forum provisions to be inapplicable or unenforceable in an action, we may incur additional
costs associated with resolving such action in other jurisdictions.

We may be subject to periodic litigation, which could result in losses or unexpected expenditure of time and resources.

From time to time, we may be called upon to defend ourselves against lawsuits relating to our business. Any litigation, regardless of its merits,
could  result  in  substantial  costs  and  a  diversion  of  management’s  attention  and  resources  that  are  needed  to  successfully  run  our  business.  Due  to  the
inherent  uncertainties  of  litigation,  we  cannot  accurately  predict  the  ultimate  outcome  of  any  such  proceedings.  An  unfavorable  outcome  in  any  such
proceedings  could  have  an  adverse  impact  on  our  business,  financial  condition  and  results  of  operations.  If  our  stock  price  is  volatile,  we  may  become
involved in securities class action lawsuits in the future.

Our failure to comply with data protection laws and regulations could lead to government enforcement actions and significant penalties against us, and
adversely impact our operating results.

EU  Member  States,  Switzerland  and  other  countries  have  adopted  data  protection  laws  and  regulations,  which  impose  significant  compliance
obligations. For example, European Union, or EU, member states and other foreign jurisdictions, including Switzerland, have adopted data protection laws
and regulations which impose significant compliance obligations. Moreover, the collection and use of personal health data in the EU is now governed under
the  EU  General  Data  Protection  Regulation,  or  the  GDPR,  effective  in  May  2018.  The  GDPR,  which  is  wide-ranging  in  scope,  imposed  several
requirements  relating  to  the  consent  of  the  individuals  to  whom  the  personal  data  relates,  the  information  provided  to  the  individuals,  the  security  and
confidentiality of the personal data, data breach notification and the use of third-party processors in connection with the processing of personal data. The
GDPR also imposes strict rules on the transfer of personal data out of the EU to the U.S., provides an enforcement authority and imposes large penalties for
noncompliance,  including  the  potential  for  fines  of  up  to  €20  million  or  4%  of  the  annual  global  revenues  of  the  noncompliant  company,  whichever  is
greater. The GDPR requirements apply not only to third-party transactions, but also to transfers of information between us and our subsidiaries, including
employee information. The GDPR increases our responsibility and liability in relation to personal data that we process, including in clinical trials, and we
may be required to put in place additional mechanisms to ensure compliance with the GDPR, which could divert management’s attention and increase our
cost of doing business. In addition, new

50

 
regulation or legislative actions regarding data privacy and security (together with applicable industry standards) may increase our costs of doing business.
However,  despite  our  ongoing  efforts,  we  may  not  be  successful  either  due  to  various  factors  within  our  control,  such  as  limited  financial  or  human
resources,  or  other  factors  outside  our  control.  It  is  also  possible  that  local  data  protection  authorities  may  have  different  interpretations  of  the  GDPR,
leading to potential inconsistencies amongst various EU member states. Any failure or alleged failure (including as a result of deficiencies in our policies,
procedures,  or  measures  relating  to  privacy,  data  security,  marketing,  or  communications)  by  us  to  comply  with  laws,  regulations,  policies,  legal  or
contractual  obligations,  industry  standards,  or  regulatory  guidance  relating  to  privacy  or  data  security,  may  result  in  governmental  investigations  and
enforcement actions, litigation, fines and penalties or adverse publicity. In addition, we expect that there will continue to be new proposed laws, regulations
and industry standards relating to privacy and data protection in the United States, the EU and other jurisdictions, such as the California Consumer Privacy
Act of 2018, which has been characterized as the first “GDPR-like” privacy statute to be enacted in the United States, and we cannot determine the impact
such future laws, regulations and standards may have on our business.

If we experience a significant disruption in our information technology systems or breaches of data security, including due to a cyber-security incident,
our business could be adversely affected.

We rely on information technology systems to keep financial records, capture laboratory data, maintain clinical trial data and corporate records,
communicate  with  staff  and  external  parties  and  operate  other  critical  functions.  Our  information  technology  systems  are  potentially  vulnerable  to
disruption due to breakdown, malicious intrusion and computer viruses or other disruptive events including but not limited to natural disaster. The impact
of the COVID-19 pandemic also poses an increased security risk, due to the mandatory remote working orders.

We  also  face  the  challenge  of  promptly  detecting  and  remediating  any  cyber-security  breaches.    Our  information  technology  systems  security
measures are focused on the prevention, detection and remediation of damage from computer viruses, unauthorized access, cyber-attack and other similar
disruptions.  However,  our  information  technology  systems  protection  measures  may  not  be  successful  in  preventing  unauthorized  access,  intrusion  and
damage.  Threats  to  our  systems  can  derive  from  human  error,  fraud  or  malice  on  the  part  of  employees  or  third  parties,  including  computer  hackers,
encryption by ransomware, or may result from technological failure.  

If we were to experience a prolonged system disruption in our information technology systems or those of certain of our vendors, it could delay or
negatively  impact  our  development  and  commercialization  of  our  product  candidates,  which  could  adversely  impact  our  business.  If  operations  at  our
facilities were disrupted, it may cause a material disruption in our business if we are not capable of restoring function on an acceptable timeframe.

In addition, as discussed above, our information technology systems are potentially vulnerable to data security breaches—whether by employees or
others, intentionally or unintentionally—which may expose sensitive or personal data to unauthorized persons. Such data security breaches could lead to
the  loss  of  trade  secrets  or  other  intellectual  property,  or  could  lead  to  the  public  exposure  of  personal  information  (including  sensitive  personal
information)  of  our  employees,  patients  in  our  clinical  trials,  customers  and  others,  any  of  which  could  have  a  material  adverse  effect  on  our  business,
financial condition and results of operations.

Moreover, a security breach or privacy violation that leads to destruction, loss, alteration, unauthorized use or access, disclosure or modification of,
personally  identifiable  information  or  personal  data,  could  harm  our  reputation,  compel  us  to  comply  with  federal,  state  and/or  international  breach
notification laws, subject us to mandatory corrective or regulatory action, require us to verify the correctness of database contents and otherwise subject us
to  liability  under  laws  and  regulations  that  protect  personal  data,  including  the  GDPR  and  the  California  Consumer  Privacy  Act  of  2018,  which  could
disrupt  our  business,  result  in  increased  costs  or  loss,  and/or  result  in  significant  legal  and  financial  exposure.  In  addition,  a  data  security  breach  could
result in loss of clinical trial data or damage to the integrity of that data.

If we are unable to implement and maintain adequate organizational and technical measures to prevent such security breaches or privacy violations,
or  to  respond  adequately  in  the  event  of  a  breach,  our  operations  could  be  disrupted,  and  we  may  suffer  loss  of  reputation,  problems  with  regulatory
authorities, financial loss and other negative consequences. In addition, these breaches and other inappropriate access can be difficult to detect, and any
delay in identifying them may lead to increased harm of the type described above.

51

 
A significant portion of our shares may be sold into the market at any time which could depress our stock price

If our stockholders sell a substantial number of shares of our common stock in the public market, our market price could decline. In connection
with the transaction with Lincoln Park, we have agreed to register under the Securities Act of 1933, as amended, the resale of shares of common stock that
have been and may be issued under the Purchase Agreement with Lincoln Park. Any such sales by Lincoln Park, or the perception that such sales may
occur, could decrease the market price of our common stock. In addition, holders of an aggregate of approximately three million shares of our common
stock have the right to require us to register these shares of common stock under specified circumstances.

Item 1B. Unresolved Staff Comments.

Dividend Policy

We have never declared or paid any cash dividends on our common stock or any other securities. We anticipate that we will retain all available
funds  and  any  future  earnings,  if  any,  for  use  in  the  operation  of  our  business  and  do  not  anticipate  paying  cash  dividends  in  the  foreseeable  future.  In
addition, future debt instruments may materially restrict our ability to pay dividends on our common stock. Payment of future cash dividends, if any, will be
at  the  discretion  of  the  board  of  directors  after  taking  into  account  various  factors,  including  our  financial  condition,  operating  results,  current  and
anticipated cash needs, the requirements of then-existing debt instruments and other factors the board of directors deems relevant.

Recent Sales of Unregistered Securities

You  should  read  the  following  Management’s  Discussion  and  Analysis  of  Financial  Condition  and  Results  of  Operations  (this  MD&A)  together
with  the  consolidated  financial  statements  and  the  related  notes  thereto  included  in  this  Annual  Report  on  Form  10-K.  This  MD&A  contains  forward-
looking  statements  that  are  subject  to  risks  and  uncertainties,  such  as  those  set  forth  in  the  sections  of  this  Annual  Report  on  Form  10-K  captioned
“Cautionary Note Regarding Forward-Looking Statements,” “Risk Factors” and elsewhere. As a result, our actual results may differ materially from those
anticipated in these forward-looking statements.

Overview

We are a clinical-stage, research and development biotechnology company focused on developing novel immunotherapeutic candidates for the treatment of
different forms of cancer. We have developed two versatile and enabling platform technologies for rational design of precision immune modulatory drugs.
Our lead clinical candidate, APVO436, and preclinical candidates, ALG.APV-527 and APVO603, were developed using our ADAPTIR™ modular protein
technology platform. Our preclinical candidate APVO442 was developed using our ADAPTIR-FLEX™ modular protein technology platform.  

The  versatile  and  robust  ADAPTIR  and  ADAPTIR-FLEX  platforms  are  designed  to  generate  monospecific,  bispecific,  and  multispecific  antibody
candidates that are capable of enhancing the human immune system against cancer cells. ADAPTIR and ADAPTIR-FLEX are both modular platforms,
which  gives  us  the  flexibility  to  generate  immunotherapeutic  candidates  with  a  variety  of  mechanisms  of  action.  This  flexibility  in  design  allows  us  to
potentially generate novel therapeutic candidates that may provide the foundation for the establishment of effective strategies against difficult to treat, as
well as advanced forms cancer. We have successfully designed and constructed numerous investigational-stage prototype product candidates based on our
ADAPTIR platform. The ADAPTIR platform technology is designed to generate monospecific and bispecific immunotherapeutic proteins that specifically
bind  to  one  or  more  targets,  for  example,  bispecific  therapeutic  molecules,  which  may  have  structural  and  functional  advantages  over  monoclonal
antibodies. The structural differences of ADAPTIR molecules over monoclonal antibodies allow for the development of ADAPTIR immunotherapeutics
that are designed to engage immune effector cells and disease targets in a novel manner to produce unique signaling responses and ultimately kill tumors or
modulate the immune system to kill tumors.

We are skilled at candidate generation, validation, and subsequent preclinical and clinical development using the ADAPTIR platform and have added the
ADAPTIR-FLEX platform to generate multi-specific candidates or other candidates to our platform capabilities.  We have developed preclinical candidates
based on the ADAPTIR-FLEX platform which are advancing in our pipeline. We are developing our ADAPTIR and ADAPTIR-FLEX molecules by way
of our protein engineering, preclinical development, process development, and clinical development capabilities.

2020 Corporate Highlights:

On February 28, 2020, we entered into an LLC Purchase Agreement with Medexus, pursuant to which we sold all of the issued and outstanding
limited  liability  company  interests  of  Aptevo  BioTherapeutics,  a  wholly  owned  subsidiary  of  Aptevo.  As  consideration  for  the  sale,  at  closing  Aptevo
received an amount equal to $30 million in cash. We used $22.1 million of the $30 million in proceeds to repay in full our previous term debt facility with
MidCap Financial, including $20 million of principal and $2.1 million in an end of facility fee, accrued interest, legal fees and prepayment fees. As a result
of the transaction, Medexus obtained all right, title and interest to the IXINITY® product and the related Hemophilia B business and intellectual property.
In addition, Aptevo BioTherapeutics personnel responsible for the sale and marketing of IXINITY also transitioned to Medexus as part of the transaction.
We receive deferred payments (royalties) from Medexus related to sales of IXINITY and may earn milestone payments in the future. Royalties are earned
at the rate of 2% of net revenue through the earlier of June 2022 or completion of the IXINITY pediatric trial being run by Medexus. After that, the royalty
rate will increase to 5%.

54

 
 
 
 
 
In July 2020, we announced that we engaged Piper Sandler & Co to sell our RUXIENCE and IXINITY royalty stream and deferred payments and
milestones,  respectively.  Aptevo  is  entitled  to  receive  a  CD20  biosimilar  product  (royalty)  payments  from  Pfizer  Inc.  of  2.5%  of  global  net  sales  of
RUXIENCE. The royalty term runs for seven years, until early 2027, and payments are due quarterly. Additionally, Aptevo is entitled to receive deferred
payments from Medexus pertaining to the net sales of IXINITY in the United States and Canada. Royalties are earned at the rate of 2% of net revenue
through the earlier of June 2022 or completion of the IXINITY pediatric trial being run by Medexus.  After that, the royalty rate will increase to 5%. The
royalty term runs for up to fifteen years, until early 2035, and payments are due quarterly. Additionally, milestone payments totaling up to $11 million may
be earned from Medexus related to certain regulatory and commercial achievements.

On August 5, 2020, we entered into a Credit and Security Agreement (Credit Agreement), with MidCap Financial. The Credit Agreement provided
us  with  up  to  $25  million  of  available  borrowing  capacity.  The  full  $25  million  was  drawn  on  the  closing  date  of  the  Credit  Agreement. The  MidCap
Financial loan has a 48-month term, is interest-only for the first 18 months, with straight-line amortization for the remaining 30 months and bears interest at
a rate of one month LIBOR plus 6.25% per annum, subject to a 1.50% LIBOR floor and a 2.50% LIBOR cap.  The loan includes additional repayment
provisions should either or both of the royalties or milestones related to IXINITY or royalties related to RUXIENCE be sold during the term of the loan.  

As of December 2020, we have advanced ALG.APV-527 into Phase 1 clinical development in a co-development 50/50 partnership. Aptevo and
Alligator plan to file a clinical trial application (CTA) in Europe in 2021 and to subsequently commence first in human dosing in the fourth quarter of 2021.

For the year ended December 31, 2020, certain of the holders of the Company’s warrants exercised warrants with a strike price of $18.20 per share,
resulting in the issuance of approximately 1.2 million shares of the Company’s common stock and aggregate proceeds to the Company of approximately
$21.2 million. As of December 31, 2020, there were 404,694 warrants outstanding.

Recent Developments

On  November  6,  2020,  Tang  filed  a  statement  on  Schedule  13D  to  report  that  Tang  had  purchased  1,760,000  shares  of  our  common  stock,
representing approximately 54% of our issued and outstanding shares of common stock as of the date of filing such Schedule 13D.  As of the date of this
Annual  Report  on  Form  10-K,  Tang  has  subsequently  been  diluted  to  a  39.6%  beneficial  ownership  position,  primarily  through  the  exercise  of  certain
warrants  that  were  issued  and  outstanding  prior  to  Tang  acquiring  its  ownership  position  in  Aptevo.  Additionally,  on  November  18,  2020,  our  Board
received a written unsolicited, non-binding indication of interest from Tang, proposing to acquire all of the outstanding shares of our common stock not
already  beneficially  owned  by  Tang  for  $50.00  per  share  in  cash,  subject  to  confirmatory  due  diligence  conducted  under  a  customary  non-disclosure
agreement. We have had a series of communications during which we attempted to negotiate a non-disclosure agreement with Tang to permit discussions
covering our nonpublic information and our operations. Further, on February 9, 2021, Tang announced its intention to nominate two candidates for election
to our board of directors at our 2021 annual meeting of stockholders and submitted an advisory stockholder proposal for consideration at our 2021 annual
meeting  to  commence  a  process  to  sell  Aptevo  to  the  highest  bidder.  We  have  incurred  and  may  continue  to  incur  additional  expenses  by  retaining  the
services of various professionals to advise us on responding to these matters.

The Aptevo Board was open to exploring the indication of interest from Tang and made earnest efforts to evaluate it. However, it was unable to do
so  because  it  was  unable  to  reach  agreement  with  Tang  on  the  terms  of  a  customary  non-disclosure  agreement,  including  limitations  on  the  use  of
confidential  information  by  Tang.    Had  agreement  on  the  terms  of  a  non-disclosure  agreement  been  reached,  it  would  have  permitted  the  exchange  of
confidential information and would have enabled both parties to conduct due diligence.  In this early stage of the Company’s development, the Aptevo
Board  believes  it  is  difficult  for  the  market  to  accurately  value  the  potential  of  Aptevo’s  proprietary  platform  technologies  and  therapeutic  candidates,
which  have  just  begun  to  demonstrate  their  effectiveness  and  potentially  life-saving  capabilities  to  the  Company’s  patients,  shareholders  and  other
stakeholders. The Board will continue to carefully evaluate any indications of interest and proposals for strategic transactions that it receives from current
shareholders or otherwise, in line with its fiduciary duties and commitment to acting in the best interests of all of the Company’s shareholders.

On March 30, 2021, the Company entered into and closed a Royalty Purchase Agreement with HCR pursuant to which the Company sold to HCR
the right to receive all royalty payments made by Pfizer in respect of net sales of RUXIENCE. Under the terms of the agreement, the Company received
$35  million  (the  Investment  Amount)  at  closing  and  the  Company  is  eligible  to  receive  additional  payments  in  aggregate  of  up  to  an  additional  $32.5
million based on the achievement of sales milestones in 2021, 2022, and 2023 (collectively, the Milestone Amounts). The Royalty Purchase Agreement
further provides that, once HCR reaches aggregate royalty payments totaling 190% of the Investment Amount plus the Milestone Amounts to the extent
paid by HCR to the Company, Aptevo will be entitled to receive 50% of any additional royalty payments by Pfizer thereafter.

In  connection  with  the  Royalty  Purchase  Agreement,  we  amended  our  Credit  Agreement  with  MidCap  Financial  and  used  $10  million  of  the
proceeds received from the Royalty Purchase Agreement with HCR to pay down the outstanding principal under this agreement from $25 million to $15
million.

Results of Operations

Except as otherwise stated below, the following discussions of our results of operations reflect the results of our continuing operations, excluding
the results related to Aptevo BioTherapeutics, which has been separated from continuing operations and reflected as a discontinued operation.  See Note 2
– Discontinued Operations to the accompanying consolidated financial statements for additional information.

Year Ended December 31, 2020 Compared to Year Ended December 31, 2019

For the year ended December 31, 2020 and 2019, we had net losses of $17.8 million and $40.4 million, respectively. As of December 31, 2020, we

had an accumulated deficit of $185.6 million.

Royalty Revenue

We recorded royalty revenue of $4.3 million for the year ended December 31, 2020. This increase is related to a 2.5% royalty we are entitled to
receive from Pfizer related to global net sales of RUXIENCE (rituximab biosimilar), which was approved by the FDA in July 2019 and launched by Pfizer
in early 2020. The payment from Pfizer relates to an agreement acquired by Aptevo as part of our spin-off from Emergent in 2016. The agreement was
originally  executed  by  Trubion  Pharmaceuticals,  which  was  subsequently  acquired  by  Emergent,  and  Wyeth,  a  wholly-own  subsidiary  of  Pfizer.  The
royalty term runs through January 2027, which is the seventh anniversary of the first commercial sale of the CD20 biosimilar.

Research and Development Expenses

We  expense  research  and  development  costs  as  incurred.  These  expenses  consist  primarily  of  the  costs  associated  with  our  research  and
development activities, including conducting preclinical studies and clinical trials, fees to professional service providers for analytical testing, independent
monitoring or other administration of our clinical trials and obtaining and evaluating data from our clinical trials and non-clinical studies, as well as costs of
contract manufacturing services for clinical trial material, and costs of materials used in clinical trials and research and development.

Our research and development expenses include:

•

•

•

•

employee salaries and related expenses, including stock-based compensation and benefits for our employees involved in our drug discovery
and development activities;

external  research  and  development  expense  incurred  under  agreements  with  third-party  contract  research  organizations  (CROs)  and
investigative sites;

manufacturing expenses and material for third-party manufacturing; and,

overhead costs such as rent, utilities and depreciation.

56

 
 
 
 
 
We  expect  our  future  research  and  development  spending  will  also  be  dependent  upon  such  factors  as  the  results  from  our  clinical  trials,  the
availability of reimbursement of research and development spending, the number of product candidates under development, the size, structure and duration
of  any  clinical  programs  that  we  may  initiate,  and  the  costs  associated  with  manufacturing  our  product  candidates  on  a  large-scale  basis  for  later  stage
clinical  trials.  We  may  experience  interruption  of  key  clinical  trial  activities,  such  as  patient  enrollment  and  clinical  trial  site  monitoring,  and  key  non-
clinical  activities  due  to  COVID-19.  While  programs  are  still  in  the  pre-clinical  trial  phase,  we  do  not  provide  a  breakdown  of  the  initial  associated
expenses, as we are often evaluating multiple product candidates simultaneously. Costs are reported in preclinical research and discovery until the program
enters the clinic.

Our principal research and development expenses by program for the year ended December 31, 2020 and 2019 are shown in the following table:

Research and development expenses decreased by $6.9 million, to $17.9 million for the year ended December 31, 2020 from $24.8 million for the
year  ended  December  31,  2019.  Expenses  decreased  primarily  related  to  decreased  spending  on  programs  discontinued  in  2019.  Pre-clinical  program,
general research and discovery costs decreased primarily due to decreased spending on outside testing and manufacturing for ALG.APV-527. This decrease
was offset by an increase in spending in APVO436 for the year ended December 31, 2020, related to increased clinical trial costs.

General and Administrative Expenses

General  and  administrative  expenses  consist  primarily  of  personnel-related  costs  and  professional  fees  in  support  of  our  executive,  business
development, finance, accounting, information technology, legal and human resource functions. Other costs include facility costs not otherwise included in
research and development expenses.

For the year ended December 31, 2020 general and administrative expenses decreased by $2.2 million, or 14%, to $14.0 million from $16.2 million

for the year ended December 31, 2019. This decrease was primarily due to reduced personnel and professional services costs.

Other Expense

Other expense consists primarily of gains or losses realized on foreign currency revaluation, costs related to debt extinguishment, accrued exit fees
on debt, and interest on debt. Other expense was $3.4 million for the year ended December 31, 2020 and $2.1 million for the year ended December 31,
2019.  This  increase  is  primarily  due  to  a  loss  on  extinguishment  of  debt  of  $2.1  million,  which  consisted  of  interest,  exit,  prepayment,  and  legal  fees
recognized during the first quarter of 2020.

Discontinued Operations

The  accompanying  consolidated  financial  statements  include  discontinued  operations  from  two  separate  transactions:  the  sale  of  hyperimmune
business  to  Saol  International  Limited  in  September  2017,  from  which  milestone  payments  were  recognized  in  2019,  and  the  sale  of  Aptevo
BioTherapeutics LLC (Aptevo BioTherapeutics) in 2020.

Income from discontinued operations was $13.2 million for the year ended December 31, 2020 and $2.6 million for the year ended December
31, 2019. On February 28, 2020, we entered into an LLC Purchase Agreement with Medexus, pursuant to which we sold all of the issued and outstanding
limited liability company interests of Aptevo BioTherapeutics, our former wholly-owned subsidiary which owns the IXINITY and related Hemophilia B
business. As a result of the transaction, Medexus obtained all rights, title, and interest to the IXINITY product and intellectual property. In addition, Aptevo
BioTherapeutics personnel responsible for the sale and marketing of IXINITY also transitioned to Medexus as part of the transaction.  

In addition to the payment received at closing, we may also earn milestone and deferred payments from Medexus in the future.  Pursuant to the
LLC Purchase Agreement, we agreed to provide certain transition services for a limited period of time following the closing. We used $22.1 million of the
$30  million  in  proceeds  to  repay  in  full  our  term  debt  facility  with  MidCap  Financial,  including  $20  million  of  principal  and  $2.1  million  in  an  end  of
facility fee, accrued interest, legal fees, and prepayment fees.

For  the  year  ended  December  31,  2019,  income  from  discontinued  operations  was  primarily  due  to  the  receipt  of  the  $4.3  million  milestone

payment from Saol International Limited, in conjunction with the sale in September 2017 of our hyperimmune business.

Income Taxes

During  the  periods  prior  to  the  spin-off  from  Emergent,  the  Company  did  not  file  separate  tax  returns  as  it  was  included  in  the  tax  returns  of
Emergent entities within the respective tax jurisdictions. The income tax provision included in these financial statements was calculated using a separate
return basis, as if the Company was a separate taxpayer. Under this approach, the Company determines its current taxes, deferred tax assets and liabilities
and related tax expense as if it were filing separate tax returns in each tax jurisdiction.

We did not have an income tax benefit or income tax expense from continuing operations in the years ended December 31, 2020 and December 31,

2019.

Off-Balance Sheet Arrangements

We did not have any off-balance sheet arrangements at December 31, 2020.

Net cash used in operating activities for the year ended December 31, 2020 was primarily due to our net operating loss of $17.8 million, the gain on
sale  of  Aptevo  BioTherapeutics  of  $14.3  million,  and  changes  in  working  capital  accounts.  Net  cash  used  in  operating  activities  for  the  year  ended
December 31, 2019 was primarily due to our net operating loss of $40.4 million, and changes in working capital accounts.

Net cash provided by investing activities for the year ended December 31, 2020, was primarily due to the cash received from the sale of Aptevo
BioTherapeutics, net of transaction fees.  For  the  year  ended  December  31,  2019,  the  net  cash  provided  by  investing  activities  was  primarily  due  to  the
receipt  of  the  $4.25  million  milestone  payment  from  Saol  International  Limited,  in  conjunction  with  the  sale  in  September  2017  of  our  hyperimmune
business, net of the purchase of property and equipment.

Net cash provided by financing activities for the year ended December 31, 2020 was primarily due to $21.2 million received from the exercises of
warrants and common stock, and proceeds of $24.7 million from the credit agreement we entered into with MidCap Financial on August 5, 2020, which
was  offset  by  the  $22.1  million  repayment  of  long-term  debt  in  the  first  quarter  of  2020.  Net  cash  provided  by  financing  activities  for  the  year  ended
December 31, 2019 was primarily due to $20.3 million received from the issuance of common stock and related warrants and the exercise of warrants. 

Sources of Liquidity

Equity Distribution Agreement

On  December  14,  2020,  we  entered  into  an  Equity  Distribution  Agreement  with  Piper  Sandler  &  Co  (Piper  Sandler).  The  Equity  Distribution
Agreement provides that, upon the terms and subject to the conditions set forth therein, we may issue and sell through Piper Sandler, acting as sales agent,
shares  of  our  common  stock  having  an  aggregate  offering  price  of  up  to  $50  million.  We  have  no  obligation  to  sell  any  such  shares  under  the  Equity
Distribution Agreement. The sale of the shares of our common stock by Piper Sandler will be effected pursuant to a Registration Statement on Form S-3
which we filed on November 9, 2017 and updated on December 14, 2020.

The Equity Distribution Agreement will terminate upon the issuance and sale of all shares under the Equity Distribution Agreement or upon the

earlier termination thereof at any time by us or Piper Sandler upon notice to the other party.

Registration Statement

We previously filed a registration statement with the Securities and Exchange Commission on November 13, 2017, amended on December 6, 2017
and  declared  effective  on  December  15,  2017  (the  Prior  Registration  Statement).  The  Prior  Registration  Statement  registered  the  offer  and  sale  of  an
indeterminate number of shares of common stock and preferred stock, an indeterminate principal amount of debt securities and an indeterminate number of
warrants to purchase common stock, preferred stock, and various series of debt securities and/or warrants to purchase any of such securities, having an
aggregate initial offering price of $150 million, of which an aggregate of $127.8 million remained unsold as of the December 14, 2020. On December 14,
2020,  we  filed  a  new  registration  statement  covering  the  offering,  issuance,  and  sale  up  to  $200  million  in  common  stock,  preferred  stock,  and  various
series of debt securities and/or warrants to purchase any of such securities, which included the unsold securities from the Prior Registration Statement.

Purchase Agreement

On December 20, 2018, we entered into the Purchase Agreement, and a registration rights agreement with Lincoln Park. Pursuant to the purchase
agreement, Lincoln Park has committed to purchase up to $35.0 million worth of our common stock over a 36-month period commencing on February 13,
2019,  the  date  the  registration  statement  covering  the  resale  of  the  shares  was  declared  effective  by  the  SEC.  Pursuant  to  this  purchase  agreement,  we
issued 13,991 commitment shares of common stock in the first quarter of 2019 and none in the year ended December 31, 2020.

59

 
 
 
 
Under the Purchase Agreement, on any business day selected by us, we may direct Lincoln Park to purchase shares of our common stock provided
that Lincoln Park’s maximum commitment on any single day does not exceed $2.0 million. The purchase price per share will be based off of prevailing
market prices of our common stock immediately preceding the time of sale; provided, however, that we cannot direct any such purchase if the prevailing
market  price  is  less  than  $1.00.  In  addition,  we  may  also  direct  Lincoln  Park  to  purchase  other  amounts  as  accelerated  purchases  or  as  additional
accelerated purchases if the closing sale price of our common stock exceeds certain threshold prices as set forth in the Purchase Agreement. We have not
sold any shares under the Purchase Agreement through the year ended December 31, 2020.

Actual  sales  of  shares  of  our  common  stock  to  Lincoln  Park  under  the  Purchase  Agreement  will  occur  at  our  discretion  from  time  to  time  and
depend on a variety of factors, including, among others, market conditions, the trading price of our common stock and additional determinations as to the
appropriate  sources  of  funding  for  our  operations.  Lincoln  Park  has  no  right  to  require  any  sales,  but  is  obligated  to  make  purchases  as  we  direct,  in
accordance with the Purchase Agreement.

Warrants

On March 11, 2019, we completed a public offering of common stock and warrants, as follows:

•

•

for a combined public offering price of $14.00 per share of common stock and related warrants, 1,417,857 shares of common stock and
related warrants with a 5-year life to purchase up to 1,417,857 shares of common stock at an exercise price of $18.20 per share,

for  a  combined  public  offering  price  of  $13.86  per  pre-funded  warrant  and  related  warrant,  pre-funded  warrants  with  a  10-year  life  to
purchase up to 153,571 shares of common stock at an exercise price of $0.14 per share and related warrants with a 5-year life to purchase
up to 153,571 shares of common stock at an exercise price of $18.20 per share. These pre-funded warrants were exercised on March 21,
2019.

For the year ended December 31, 2020, certain of the holders of the Company’s warrants exercised warrants with a strike price of $18.20 per share,
resulting  in  the  issuance  of  1,166,735  million  shares  of  the  Company’s  common  stock  and  aggregate  proceeds  to  the  Company  of  approximately  $21.2
million. As of December 31, 2020, there were 404,694 warrants outstanding.

Liquidity

We  have  financed  our  operations  to  date  primarily  through  revenue  generated  from  our  commercial  products,  royalty  payments  from  Pfizer,
deferred payments from Medexus, the sale of our hyperimmune products business in September 2017, the sale of Aptevo BioTherapeutics on February 28,
2020,  public  offerings  of  our  common  stock,  loan  proceeds,  milestone  payments,  research  and  development  funding  from  strategic  partners,  and  funds
received  at  the  date  of  our  spin-off  from  Emergent. We  had  a  net  loss  of  $17.8  million  and  $40.4  million  for  the  years  ended  December  31,  2020  and
December 31, 2019, respectively. We had cash and cash equivalents of $39.9 million, restricted cash – current of $2.6 million, and an accumulated deficit
of $185.6 million as of December 31, 2020.

For the year ended December 31, 2020, net cash used in our operating activities was $29.3 million.

Our future success is dependent on our ability to develop our product candidates and ultimately upon our ability to attain profitable operations. We
anticipate  that  we  will  continue  to  incur  significant  operating  losses  for  the  next  several  years  as  we  incur  expenses  to  continue  to  execute  on  our
development strategy to advance our preclinical and clinical stage assets. We will not generate revenues from our development stage product candidates
unless  and/or  until  we  or  our  collaborators  successfully  complete  development  and  obtain  regulatory  approval  for  such  product  candidates,  which  we
expect  will  take  a  number  of  years  and  is  subject  to  significant  uncertainty.  If  we  obtain  regulatory  approval  for  one  of  our  development  stage  product
candidates, we expect to incur significant commercialization expenses related to sales, marketing, manufacturing and distribution, to the extent that such
costs are not paid by collaborators. We do not have sufficient cash to complete the clinical development of any of our development stage product candidates
and will require additional funding in order to complete the development activities required for regulatory approval of such product candidates. We will
require substantial additional funds to continue our development programs and to fulfill our planned operating goals.

60

 
 
 
 
 
Due to COVID-19, we may experience delays in opportunities to partner our product candidates, due to financial and other impacts on potential
partners. Additionally, we may experience potential impacts on our future deferred payments and milestones from Medexus due to effects of the COVID-
19 pandemic, which may impact Medexus’ ability to continue to successfully commercialize the IXINITY businesses, respectively. We  believe  that  our
existing cash resources, the Investment Amount from the Royalty Purchase Agreement with HCR, the cash to be generated from future IXINITY deferred
payments,  access  to  cash  under  the  Purchase  Agreement  with  Lincoln  Park  LLC,  release  of  restricted  cash  securing  letters  of  credit,  and  the  Credit
Agreement with Midcap Financial, will be sufficient to meet our projected operating requirements and debt service for at least twelve months from the date
of this filing of this Annual Report on Form 10-K.

In  July  2020,  we  announced  that  we  engaged  Piper  Sandler  to  sell  our  RUXIENCE  and  IXINITY  royalty  streams  and,  deferred  payments  and
milestones, respectively, in order to provide additional funding for the development of our product candidates. On March 30, 2021, the Company entered
into and closed a Royalty Purchase Agreement with HCR pursuant to which the Company sold to HCR the right to receive all royalty payments made by
Pfizer in respect of net sales of RUXIENCE. Under the terms of the agreement, the Company received $35 million (the Investment Amount) at closing and
the Company is eligible to receive additional payments in aggregate of up to an additional $32.5 million based on the achievement of sales milestones in
2021, 2022, and 2023 (collectively, the Milestone Amounts). The Royalty Purchase Agreement further provides that, once HCR reaches aggregate royalty
payments totaling 190% of the Investment Amount plus the Milestone Amounts to the extent paid by HCR to the Company, Aptevo will be entitled to
receive 50% of any additional royalty payments by Pfizer thereafter.

There  are  numerous  risks  and  uncertainties  associated  with  research,  development,  and  commercialization  of  pharmaceutical  products.

Accordingly, our future funding requirements may vary from our current expectations and will depend on many factors, including, but not limited to:

•

•

•

•

•

•

•

•

•

•

our ability to establish and maintain strategic partnerships, licensing or other arrangements and the financial terms of such agreements;

the number and characteristics of the product candidates we pursue;

the  scope,  progress,  results,  and  costs  of  researching  and  developing  our  product  candidates,  and  of  conducting  preclinical  and  clinical
trials;

the timing of, and the costs involved in, completing our clinical trials, and obtaining regulatory approvals for our product candidates;

the costs involved in preparing, filing, prosecuting, maintaining, defending and enforcing patent claims, including litigation costs and the
outcome of such litigation;

the cost of commercialization activities if any of our product candidates are approved for sale, including marketing, sales, and distribution
costs;

the cost of manufacturing our product candidates and any products we successfully commercialize;

the cost of attracting and retaining skilled personnel;

whether and to what extent future proceeds are received under our royalty purchase agreement with HCR; and,

the timing, receipt and amount of any milestone payments and deferred payments from Medexus with respect to IXINITY.

If we are unable to raise substantial additional capital in the next year, whether on terms that are acceptable to us or at all, then we may be required

to:

•

•

delay, limit, reduce or terminate our clinical trials or other development activities for one or more of our product candidates; and/or,

delay, limit, reduce or terminate our establishment of other activities that may be necessary to commercialize our product candidates, if
approved.

61

 
 
 
 
 
 
 
 
 
 
 
 
 
The sale of additional equity or convertible debt securities may result in additional dilution to our stockholders. If we raise additional funds through
the issuance of debt securities or preferred stock or through credit facilities, these securities and/or the loans under credit facilities could provide for rights
senior to those of our common stock and could contain covenants that would restrict our operations. Additional funds may not be available when we need
them, on terms that are acceptable to us, or at all. We also expect to seek additional funds through arrangements with collaborators, licensees or other third
parties. These arrangements would generally require us to relinquish or encumber rights to some of our technologies or drug candidates, and we may not be
able to enter into such arrangements on acceptable terms, if at all. Due to COVID-19, we may experience delays in clinical trials and pre-clinical work, and
opportunities to partner our product candidates, due to financial and other impacts on potential partners.

Contractual Obligations

We have an operating lease related to our office and laboratory space in Seattle, Washington. This lease was amended and extended in March 2019.
The term of the amended lease is through April 2030 and we have two options to extend the lease term, each by five years, as well as a one-time option to
terminate the lease in April 2023.

In January 2020, we entered into a contract with The Leukemia & Lymphoma Society (LLS) to be part of an ongoing national AML master clinical
trial called the ‘Beat AML Master Clinical Trial.’ The Beat AML Master Clinical Trial provides access to leading academic cancer centers and allows us to
study APVO436 in a front-line AML setting. Our purchase obligation for the Beat AML Master Clinical Trial totals $8.1 million over the next three years,
with payments anticipated to begin in 2021. We note that the Clinical Trial Participation Agreement contains a termination for convenience clause where
we may terminate the agreement with 180 days prior written notice.

On August 5, 2020, we entered into a new Credit and Security Agreement (Credit Agreement), with MidCap Financial. The Credit Agreement provided us
with  up  to  $25  million  of  available  borrowing  capacity.  The  MidCap  Financial  loan  has  a  48  month  term,  is  interest-only  for  the  first  18  months,  with
straight-line amortization for the remaining 30 months and bears interest at a rate of one month LIBOR plus 6.25% per annum, subject to a 1.50% LIBOR
floor and a 2.50% LIBOR cap. Additionally, on March 30, 2021, we amended our Credit Agreement with MidCap Financial and used $10 million of the
proceeds received from the Royalty Purchase Agreement with HCR to pay down the outstanding principal under this agreement from $25 million to $15
million.

Critical Accounting Policies and Significant Judgements and Estimates

The  preparation  of  our  consolidated  financial  statements  in  conformity  with  accounting  principles  generally  accepted  in  the  United  States,  or
GAAP, requires management to make estimates and assumptions that affect the amounts reported in the financial statements and accompanying notes. We
base  our  estimates  on  historical  experience  and  on  various  other  factors.  Although  we  believe  that  our  judgments  and  estimates  are  appropriate,  actual
results may differ materially from our estimates and changes in these estimates are recorded when known. An accounting policy is considered critical if it is
important to a company’s financial condition and results of operations and if it requires the exercise of significant judgment and the use of estimates on the
part of management in its application.

While our significant accounting policies are more fully described in Note 1 to our audited consolidated financial statements appearing elsewhere
in  this  report,  we  believe  the  following  accounting  policies  are  the  most  critical  to  the  judgments  and  estimates  we  use  in  the  preparation  of  our
consolidated financial statements.

Research and Development Expenses

Research and development expenses are expensed as incurred. Research and development costs primarily consist of internal labor costs, fees paid
to  outside  service  providers  and  the  costs  of  materials  used  in  clinical  trials  and  research  and  development.  Other  research  and  development  expenses
include facility, maintenance, and related support expenses.

A substantial portion of our pre-clinical studies and all of our clinical studies have been performed by third-party contract research organizations
(CRO). We review the activities performed by the CROs each period. For pre-clinical studies, the significant factors used in estimating accruals include the
percentage  of  work  completed  to  date  and  contract  milestones  achieved.  For  clinical  study  expenses,  the  significant  factors  used  in  estimating  accruals
include the number of patients enrolled and percentage of work completed to date. Our estimates are highly dependent upon the timeliness and accuracy of
the data provided by our CROs regarding the status of each program and total program spending and adjustments are made when deemed necessary.

Stock-Based Compensation

Under ASC 718, Compensation—Stock-based Compensation, we measure and recognize compensation expense for restricted stock units (RSUs),
and stock options granted to our employees and directors based as of the fair value of the awards on the date of grant. The fair value of stock options is
estimated at the date of grant using the Black-Scholes option pricing model that requires management to apply judgment and make estimates, including:

•

•

•

•

•

the expected term of the stock option award, which we calculate using the simplified method, as permitted by the SEC Staff Accounting
Bulletin No. 110, Share-Based Payment, as we have insufficient historical information regarding our stock options to provide a basis for an
estimate;

the expected volatility of our underlying common stock, which we estimate based on the historical volatility of a representative group of
publicly traded biopharmaceutical companies with similar characteristics to us, and our own historical and implied future volatility;

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

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

the fair value of our common stock on the date of grant.

Stock-based compensation expense for RSUs, and stock options is recognized on a straight-line basis over the requisite service period, which is
generally the vesting period of the respective award. We are required to estimate a forfeiture rate to calculate the stock-based compensation expense for our
awards.  Our  forfeiture  rate  is  based  on  an  analysis  of  our  actual  forfeitures  since  the  adoption  of  our  equity  award  plan.  We  routinely  evaluate  the
appropriateness  of  the  forfeiture  rate  based  on  actual  forfeiture  experience,  analysis  of  employee  turnover,  and  expectations  of  future  option  exercise
behavior.

Income Taxes

Income taxes are accounted for using the liability method. Deferred tax assets and liabilities are recognized for future tax consequences attributable
to differences between financial statement carrying amounts of existing assets and liabilities and their respective tax bases and net operating loss and tax
credit carry forwards. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the year in which those
temporary differences are expected to be recovered or settled.

Aptevo’s ability to realize deferred tax assets depends upon future taxable income as well as the limitations discussed below. For financial reporting
purposes, a deferred tax asset must be reduced by a valuation allowance if it is more likely than not that some portion or all of the deferred tax assets will
not be realized prior to expiration. Aptevo considers historical and future taxable income, future reversals of existing taxable temporary differences, taxable
income in prior carryback years, and ongoing tax planning strategies in assessing the need for valuation allowances. In general, if Aptevo determines that it
is  more  likely  than  not  to  realize  more  than  the  recorded  amounts  of  net  deferred  tax  assets  in  the  future,  Aptevo  will  reverse  all  or  a  portion  of  the
valuation  allowance  established  against  its  deferred  tax  assets,  resulting  in  a  decrease  to  the  provision  for  income  taxes  in  the  period  in  which  the
determination is made. Likewise, if Aptevo determines that it is not more likely than not to realize all or part of the net deferred tax asset in the future,
Aptevo will establish a valuation allowance against deferred tax assets, with an offsetting increase to the provision for income taxes, in the period in which
the determination is made.

Because tax laws are complex and subject to different interpretations, significant judgment is required. As a result, Aptevo makes certain estimates
and assumptions, in (1) calculating Aptevo’s income tax expense, deferred tax assets and deferred tax liabilities, (2) determining any valuation allowance
recorded  against  deferred  tax  assets  and  (3)  evaluating  the  amount  of  unrecognized  tax  benefits,  as  well  as  the  interest  and  penalties  related  to  such
uncertain tax positions. Aptevo’s estimates and assumptions may differ significantly from tax benefits ultimately realized.

Report of Independent Registered Public Accounting Firm

To the Stockholders and the Board of Directors of
Aptevo Therapeutics Inc.

Opinion on the Financial Statements

We  have  audited  the  accompanying  consolidated  balance  sheet  of  Aptevo  Therapeutics  Inc.  (the  “Company”)  as  of  December  31,  2020,  the  related
consolidated statements of operations, cash flows, and changes in stockholders’ equity for the year then ended, 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 consolidated
financial position of the Company as of December 31, 2020, and the consolidated results of its operations and its cash flows for the year then ended, in
conformity with accounting principles generally accepted in the United States of America.

Basis for Opinion

These consolidated financial statements are the responsibility of the Company’s management. Our responsibility is to express an opinion on the Company’s
consolidated financial statements based on our audit. We are a public accounting firm registered with the Public Company Accounting Oversight Board
(United States) (“PCAOB”) and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the
applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our 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  the  consolidated  financial  statements  are  free  of  material  misstatement,  whether  due  to  error  or  fraud.  The  Company  is  not
required to have, nor were we engaged to perform, an audit of its internal control over financial reporting. As part of our audit we are required to obtain an
understanding of internal control over financial reporting but not for the purpose of expressing an opinion on the effectiveness of the Company’s internal
control over financial reporting. Accordingly, we express no such opinion.

Our  audit  included  performing  procedures  to  assess  the  risks  of  material  misstatement  of  the  consolidated financial  statements,  whether  due  to  error  or
fraud,  and  performing  procedures  to  respond  to  those  risks.  Such  procedures  included  examining,  on  a  test  basis,  evidence  regarding  the  amounts  and
disclosures in the consolidated financial statements. Our audit also included evaluating the accounting principles used and significant estimates made by
management, as well as evaluating the overall presentation of the consolidated financial statements. We believe that our audit provides a reasonable basis
for our opinion.

Notes to Consolidated Financial Statements

Note 1. Nature of Business and Significant Accounting Policies

Organization and Liquidity

Aptevo  Therapeutics  Inc.  (Aptevo,  we,  us,  or  the  Company)  is  a  clinical-stage,  research  and  development  biotechnology  company  focused  on
developing  novel  immunotherapeutic  candidates  for  the  treatment  of  different  forms  cancer.  We  have  developed  two  versatile  and  enabling  platform
technologies for rational design of precision immune stimulatory drugs. Our lead clinical candidate, APVO436, and preclinical candidates, ALG.APV-527
and APVO603, were developed using our ADAPTIR™ modular protein technology platform. Our preclinical candidate APVO442 was developed using
our ADAPTIR-FLEX™ modular protein technology platform.  

We are currently trading on the Nasdaq Capital Market under the symbol “APVO.”

On February 28, 2020, we entered into an LLC Purchase Agreement with Medexus, pursuant to which we sold all of the issued and outstanding
limited liability company interests of Aptevo BioTherapeutics LLC, a wholly owned subsidiary of Aptevo. As a result of the transaction, Medexus obtained
all right, title and interest to the IXINITY® product and the related Hemophilia B business and intellectual property. In addition, Aptevo BioTherapeutics
personnel responsible for the sale and marketing of IXINITY also transitioned to Medexus as part of the transaction. Aptevo BioTherapeutics met all the
conditions to be classified as a discontinued operation, since the sale of Aptevo BioTherapeutics represented a strategic shift that will have a major effect
on  the  Company’s  operations  and  financial  results.  Aptevo  will  not  have  further  significant  involvement  in  the  operations  of  the  discontinued  Aptevo
BioTherapeutics business. The operating results of Aptevo BioTherapeutics are reported as income (loss) from discontinued operations, in the consolidated
statements of operations for all periods presented. The gain recognized on the sale of Aptevo BioTherapeutics is presented in income from discontinued
operations in the consolidated statement of operations. In addition, on the consolidated balance sheet as of December 31, 2019, the assets and liabilities
held for sale have been presented separately. See Note 2 – Discontinued Operations for additional information.

The accompanying financial statements have been prepared on a basis that assumes we will continue as a going concern and which contemplates
the realization of assets, satisfaction of liabilities, and commitments in the normal course of business. We have suffered recurring losses from operations
and negative cash flows from operating activities. We believe that our existing cash resources, the cash to be generated from future royalty and deferred
payments, the Investment Amount from the Royalty Purchase Agreement with HCR, the cash generated from warrant exercises, access to cash under the
Purchase  Agreement  with  Lincoln  Park,  release  of  restricted  cash  securing  letters  of  credit,  and  the  Credit  Agreement  of  $25  million  with  Midcap
Financial, will be sufficient to meet our projected operating requirements and debt service for at least twelve months from the date of issuance of these
financial statements. We expect to raise additional funds to support our operating and capital needs in 2021.

We continue to face significant challenges and uncertainties and, as a result, our available capital resources may be consumed more rapidly than
currently expected due to: (a) changes we may make to the business that affect ongoing operating expenses; (b) changes we may make in our business
strategy;  (c)  changes  we  may  make  in  our  research  and  development  spending  plans;  (d)  potential  decreases  in  our  expected  milestone  and  deferred
payments from Medexus with respect to IXINITY; (e) whether and to what extent future proceeds are received under our royalty purchase agreement with
HCR; and (f) other items affecting our forecasted level of expenditures and use of cash resources. We may attempt to obtain additional funding through our
existing equity sales agreement with Lincoln Park Financial LLC or our Equity Distribution Agreement with Piper Sandler & Co (Piper Sandler), or other
public or private financing, collaborative arrangements with strategic partners, or through credit lines or other debt financing sources to increase the funds
available to fund operations. However, we may not be able to secure such funding in a timely manner or on favorable terms, if at all. Furthermore, if we
issue equity or debt securities to raise additional funds, our existing stockholders may experience dilution, and the new equity or debt securities may have
rights, preferences, and privileges senior to those of our existing stockholders. If we raise additional funds through collaboration, licensing, or other similar
arrangements, it may be necessary to relinquish valuable rights to our potential products or proprietary technologies, or grant licenses on terms that are not
favorable to us. Without additional funds, we may be forced to delay, scale back, or eliminate some of our research and development activities or other
operations and potentially delay product development in an effort to provide sufficient funds to continue our operations. If any of these events occurs, our
ability  to  achieve  our  development  and  commercialization  goals  may  be  adversely  affected.  Given  the  global  economic  climate  and  additional  or
unforeseen  effects  from  the  COVID-19  pandemic,  we  may  experience  delays  or  difficulties  to  the  financing  environment  and  raising  capital  due  to
economic uncertainty.

On November 6, 2020, Tang Capital Partners LP, Tang Capital Management, LLC and Kevin Tang (collectively, “Tang”) jointly filed a statement
on Schedule 13D to report that Tang had purchased 1,760,000 shares of our common stock, representing approximately 54% of the Company’s issued and
outstanding shares of common stock as of the date of filing such Schedule 13D.  As of the date of this Annual Report on Form 10-K, Tang has subsequently
been diluted to a 39.6% beneficial ownership position, primarily through the exercise of certain warrants that were issued and outstanding prior to Tang
acquiring  its  ownership  position  in  Aptevo.  Additionally,  on  November  18,  2020,  our  Board  received  a  written  unsolicited,  non-binding  indication  of
interest from Tang, proposing to acquire all of the outstanding shares of our common stock not already beneficially owned by Tang for $50.00 per share in
cash, subject to confirmatory due diligence conducted under a customary non-disclosure agreement. We have had a series of communications with Tang
during which we attempted to negotiate a non-disclosure agreement to permit discussions covering our nonpublic information and our operations. Further,
on  February  9,  2021,  Tang  announced  its  intention  to  nominate  two  candidates  for  election  to  our  board  of  directors  at  our  2021  annual  meeting  of
stockholders and submitted an advisory stockholder proposal for consideration at our 2021 annual meeting of stockholders to commence a process to sell
Aptevo to the highest bidder. We have incurred and may continue to incur additional expenses by retaining the services of various professionals to advise
us on responding to these matters.

The Aptevo Board was open to exploring the indication of interest from Tang and made earnest efforts to evaluate it. However, it was unable to do
so  because  it  was  unable  to  reach  agreement  with  Tang  on  the  terms  of  a  customary  non-disclosure  agreement,  including  limitations  on  the  use  of
confidential  information  by  Tang.    Had  agreement  on  the  terms  of  a  non-disclosure  agreement  been  reached,  it  would  have  permitted  the  exchange  of
confidential information and would have enabled both parties to conduct due diligence.  In this early stage of the Company’s development, the Aptevo
Board  believes  it  is  difficult  for  the  market  to  accurately  value  the  potential  of  Aptevo’s  proprietary  platform  technologies  and  therapeutic  candidates,
which  have  just  begun  to  demonstrate  their  effectiveness  and  potentially  life-saving  capabilities  to  the  Company’s  patients,  shareholders  and  other
stakeholders. The Board will continue to carefully evaluate any indications of interest and proposals for strategic transactions that it receives from current
shareholders or otherwise, in line with its fiduciary duties and commitment to acting in the best interests of all of the Company’s shareholders.

Basis of Presentation

The  accompanying  consolidated  financial  statements  have  been  prepared  in  accordance  with  U.S.  generally  accepted  accounting  principles
(GAAP). These consolidated financial statements include all adjustments, which include normal recurring adjustments, necessary for the fair presentation
of the Company’s financial position.

The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported
amounts  of  assets  and  liabilities  at  the  date  of  the  financial  statements  and  the  reported  amounts  of  revenues  and  expenses  during  the  reporting  period.
Actual results could differ from these estimates and changes in these estimates are recorded when known.

In March 2020, we effected a 1-for-14 reverse stock split (the “Reverse Split”) of our common stock pursuant to which every 14 shares of our
common stock issued and outstanding as of March 26, 2020 were automatically combined into one issued and outstanding share of common stock.  No
fractional shares were issued as a result of the reverse stock split. Stockholders of record who would otherwise have been entitled to receive a fractional
share received a cash payment in lieu thereof. All share and per share information with respect to our common stock have been restated to reflect the effect
of the Reverse Split for all periods presented. Refer to Note 9 for additional information.  

Significant Accounting Policies

Use of Estimates

The preparation of financial statements in conformity with GAAP requires estimates and assumptions that affect the reported amounts of assets and
liabilities,  revenues  and  expenses,  and  related  disclosures  of  contingent  liabilities  in  the  consolidated  financial  statements  and  accompanying  notes.
Estimates  are  used  for,  but  not  limited  to,  useful  lives  of  equipment,  clinical  trial  accruals,  income  taxes,  commitments  and  contingencies,  stock-based
compensation, and collectability of receivables. Given the global economic climate and additional or unforeseen effects from the COVID-19 pandemic,
these estimates are becoming more challenging, and actual results could differ materially from those estimates.

72

 
 
Principles of Consolidation

The consolidated financial statements include the accounts of the company and its wholly owned subsidiaries: Aptevo Research and Development
LLC  and  Aptevo  BioTherapeutics  LLC  (for  the  period  prior  to  the  sale  on  February  28,  2020).  All  intercompany  balances  and  transactions  have  been
eliminated.

Cash Equivalents

Cash equivalents are highly liquid investments with a maturity of 90 days or less at the date of purchase and include time deposits and investments

in money market funds with commercial banks and financial institutions.

Restricted Cash

As  of  December  31,  2020,  we  had  current  restricted  cash  of  $2.6  million  related  to  securing  letters  of  credit.  We  classify  our  restricted  cash  as

either current or non-current based on the term of the underlying letters of credit.

Concentrations of Credit Risk

Financial  instruments  that  potentially  subject  Aptevo  to  concentrations  of  credit  risk  consist  primarily  of  cash  and  cash  equivalents,  certain
investments and royalties receivable. Aptevo places its cash and cash equivalents with high quality financial institutions and may maintain cash balances in
excess of insured limits. Management believes that the financial risks associated with its cash and cash equivalents are minimal.

Property and Equipment

Property and equipment are stated at cost. Depreciation is computed using the straight-line method over the following estimated useful lives:

Furniture and equipment
Software and hardware
Leasehold improvements

7-10 years
3-5 years or product life
Lesser of the asset life or the remaining lease term

Upon retirement or sale, the cost of assets disposed of and the related accumulated depreciation are removed from the accounts and any resulting

gain or loss is credited or charged to operations. Repairs and maintenance costs are expensed as incurred.

Leases

We determine if an arrangement is a lease at inception date. Leases are to be classified as finance or operating leases at the lease commencement
date, which affects the classification of expense recognition in the income statement. Right-of-use assets represent the right to use an underlying asset for
the  lease  term  and  lease  liabilities  represent  the  obligation  to  make  lease  payments,  as  agreed  to  in  the  lease.  Operating  lease  liabilities  and  the
corresponding right-of-use assets are recognized based on the present value of the future minimum lease payments over the lease term at commencement
date.  An  operating  right-of-use  asset  is  measured  as  the  amount  of  the  initial  measurement  of  the  lease  liability,  adjusted  for  prepaid  or  accrued  lease
payments, the remaining balance of any lease incentive received, unamortized initial direct costs, and any impairment of the right-of-use asset. The initial
measurement of the lease liabilities and right-to-use assets of finance leases is the same as for operating leases. We include options to extend the lease and
certain termination options in our lease liability and right-of-use asset when it is reasonably certain that we will exercise those options.

As our existing leases do not contain an implicit interest rate, we estimate our incremental borrowing rate (IBR) based on information available at
commencement date in determining the present value of future payments. Due to the significant judgment involved and the complex analysis needed to
determine  this  discount  rate,  we  engaged  a  third-party  valuation  specialist  to  advise  us  in  our  determination  of  our  IBR  for  the  initial  adoption  of  the
standard.

73

 
 
 
 
 
 
Lease  expense  for  operating  leases  is  recognized  on  a  straight-line  basis  over  the  lease  term  as  part  of  our  selling,  general  and  administrative
expenses  and  our  research  and  development  expenses  on  our  consolidated  statements  of  operations.  Lease  expense  for  financing  leases  consists  of
amortization of the right-of-use asset and interest on the lease liability as part of our research and development expenses on our consolidated statements of
operations.

Fair Value of Financial Instruments

We  measure  and  record  cash  equivalents  and  investment  securities  considered  available-for-sale  at  fair  value  in  the  accompanying  financial
statements. Fair value is defined as the exchange price that would be received for an asset or paid to transfer a liability, an exit price, in the principal or
most advantageous market for the asset or liability in an orderly transaction between market participants on 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 carrying amounts of our short-term financial instruments, which include cash and cash equivalents, royalties receivable and accounts payable,

approximate their fair value due to their short maturities.

Debt Issuance Costs

Aptevo  defers  costs  related  to  debt  issuance  and  amortizes  these  costs  to  interest  expense  over  the  term  of  the  debt,  using  the  effective  interest

method. Debt issuance costs are presented in the consolidated balance sheet as a reduction of the carrying amount of the debt liability.

Revenue Recognition – Royalties, Deferred Payments and Milestones

We are entitled to receive royalty revenue from Pfizer related to sales of a rituximab biosimilar product, RUXIENCE. The payment from Pfizer
relates to an agreement acquired by Aptevo as part of its spin-off from Emergent BioSolutions in 2016, which applies a fixed royalty rate of 2.5% on global
net  sales.  The  agreement  was  originally  executed  by  Trubion  Pharmaceuticals  (which  was  subsequently  acquired  by  Emergent  BioSolutions  Inc.)  and
Wyeth  (a  wholly-owned  subsidiary  of  Pfizer).  The  royalty  term  runs  until  the  seventh  anniversary  of  the  first  commercial  sale  of  the  CD20  biosimilar.
CD20 biosimilar product (royalty) payments to Aptevo are due within 60 days after the end of each quarter. We do not have future performance obligations
under  this  agreement.  We  apply  the  royalty  recognition  constraint  required  under  the  guidance  for  sales-based  royalties,  which  requires  a  sales-based
royalty to be recorded no sooner than the underlying sale. Therefore, royalties on sales of products commercialized by Pfizer are recognized in the quarter
the product is sold. Pfizer generally reports sales information to us within 60 days of quarter end. Unless we receive finalized sales information for the
respective quarter, we estimate the expected royalty proceeds based on an analysis of historical experience, analyst expectations, interim data provided by
Pfizer, including their publicly announced sales, and other publicly available information. Differences between actual and estimated royalty revenues are
adjusted for in the period in which they become known, typically the following quarter.

We  are  entitled  to  receive  future  deferred  payments  and  future  milestone  payments  from  Medexus.  The  payments  from  Medexus  constitute
contingent consideration related to our sale of IXINITY in 2020, which is treated as a discontinued operation in the accompanying statement of operations.
We  treat  contingent  consideration  arising  from  discontinued  operations  as  gain  contingencies  in  accordance  with  ASC  450-30  –  Contingencies:  Gain
Contingencies,  whereby  such  gain  contingencies  usually  are  not  recognized  in  the  financial  statements  until  the  period  in  which  all  contingencies  are
resolved  and  the  gain  is  realized  or  realizable.  As  Medexus  communicates  payment  amounts  and  sales  details  subsequent  to  quarter-end,  and  there  is
uncertainty as to the amount of the payment before quarter-end, we record deferred payments in the quarter the payment is received.

Research and Development Expenses

Research and development expenses are expensed as incurred. Research and development costs primarily consist of internal labor costs, fees paid
to  outside  service  providers  and  the  costs  of  materials  used  in  clinical  trials  and  research  and  development.  Other  research  and  development  expenses
include facility, maintenance, and related support expenses.

74

 
 
A  substantial  portion  of  Aptevo’s  pre-clinical  studies  and  all  of  its  clinical  studies  have  been  performed  by  third-party  CROs.  The  Company
reviews the activities performed by the CROs each period. For pre-clinical studies, the significant factors used in estimating accruals include the percentage
of  work  completed  to  date  and  contract  milestones  achieved.  For  clinical  study  expenses,  the  significant  factors  used  in  estimating  accruals  include  the
number of patients enrolled and services provided but not yet invoiced. The Company’s estimates are highly dependent upon the timeliness and accuracy of
the data provided by its CROs regarding the status of each program and total program spending and adjustments are made when deemed necessary.

General and Administrative Expenses

General  and  administrative  expenses  consist  primarily  of  personnel-related  costs  and  professional  fees  in  support  of  our  executive,  business
development, finance, accounting, information technology, legal and human resource functions. Other costs include facility costs not otherwise included in
research and development expense.

Stock-Based Compensation

Under  the  ASC  718,  Compensation—Stock-based  Compensation,  we  measure  and  recognize  compensation  expense  for  restricted  stock  units
(RSUs), and stock options granted to our employees and directors based on the fair value of the awards as of the date of grant. The fair value of stock
options is estimated at the date of grant using the Black-Scholes option pricing model that requires management to apply judgment and make estimates,
including:

•

•

•

•

•

the expected term of the stock option award, which we calculate using the simplified method, as permitted by the SEC Staff Accounting
Bulletin No. 110, Share-Based Payment, as we have insufficient historical information regarding our stock options to provide a basis for an
estimate;

the expected volatility of our underlying common stock, which we estimate based on the historical volatility of the historical and implied
future volatility of our common stock;

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

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

the fair value of our common stock on the date of grant.

Stock-based compensation expense for RSUs is recognized on a straight-line basis over the vesting period of the respective award. Stock-based
compensation  expense  for  our  stock  options,  both  converted  and  Aptevo  granted,  is  recognized  on  a  straight-line  basis  over  the  vesting  period  of  the
respective award.

We have elected to estimate a forfeiture rate to calculate the stock-based compensation expense for our awards. We have estimated a forfeiture rate
of sixteen-percent. We routinely evaluate the appropriateness of the forfeiture rate based on actual forfeiture experience, analysis of employee turnover, and
expectations of future option exercise behavior.

Income Taxes

Income taxes are accounted for using the liability method. Deferred tax assets and liabilities are recognized for future tax consequences attributable
to differences between financial statement carrying amounts of existing assets and liabilities and their respective tax bases and net operating loss and tax
credit carry forwards. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the year in which those
temporary differences are expected to be recovered or settled.

Aptevo’s  ability  to  realize  deferred  tax  assets  depends  upon  future  taxable  income,  as  well  as  the  limitations  discussed  below.  For  financial
reporting purposes, a deferred tax asset must be reduced by a valuation allowance if it is more likely than not that some portion or all of the deferred tax
assets  will  not  be  realized  prior  to  expiration.  Aptevo  considers  historical  and  future  taxable  income,  future  reversals  of  existing  taxable  temporary
differences, taxable income in prior carryback years, and ongoing tax planning strategies in assessing the need for valuation

75

 
 
 
 
 
 
allowances. In general, if Aptevo determines that it is more likely than not to realize more than the recorded amounts of net deferred tax assets in the future,
Aptevo will reverse all or a portion of the valuation allowance established against its deferred tax assets, resulting in a decrease to the provision for income
taxes in the period in which the determination is made. Likewise, if Aptevo determines that it is not more likely than not to realize all or part of the net
deferred  tax  asset  in  the  future,  Aptevo  will  establish  a  valuation  allowance  against  deferred  tax  assets,  with  an  offsetting  increase  to  the  provision  for
income taxes, in the period in which the determination is made.

Because tax laws are complex and subject to different interpretations, significant judgment is required. As a result, Aptevo makes certain estimates
and assumptions, in (1) calculating Aptevo’s income tax expense, deferred tax assets and deferred tax liabilities, (2) determining any valuation allowance
recorded  against  deferred  tax  assets  and  (3)  evaluating  the  amount  of  unrecognized  tax  benefits,  as  well  as  the  interest  and  penalties  related  to  such
uncertain tax positions. Aptevo’s estimates and assumptions may differ significantly from tax benefits ultimately realized.

Segment Reporting

We  have  determined  that  we  operate  in  a  single  segment  and  have  one  reporting  unit:  the  discovery  and  development  of  novel  oncology

therapeutics.

Note 2. Discontinued Operations

The accompanying financial statements include discontinued operations from two separate transactions: the sale of our Hyperimmune business in

2017, from which milestone payments were recognized in 2019, and our Aptevo BioTherapeutics LLC business, which was sold in 2020.

In the third quarter of 2019, we received a $4.25 million milestone payment from Saol International Limited, in connection with the sale of our
hyperimmune business in September 2017. No additional amounts are outstanding related to the milestones. This was recorded as a gain of $4.25 million in
discontinued operations on the consolidated statement of operations.

On  February  28,  2020,  we  entered  into  an  LLC  Purchase  Agreement  with  Medexus,  pursuant  to  which  Aptevo  sold  all  of  the  issued  and
outstanding limited liability company interests of Aptevo BioTherapeutics, a wholly owned subsidiary of Aptevo. As a result of the transaction, Medexus
obtained all right, title and interest to the IXINITY product and the related Hemophilia B business and intellectual property.

The net gain on sale of Aptevo BioTherapeutics, totaling $14.3 million, was calculated as the difference between the fair value of the consideration
received for Aptevo BioTherapeutics, less the net carrying value of the assets transferred to Medexus, less the transaction costs incurred and a working
capital adjustment.

The following table summarizes the gain on sale (in thousands) for the year ended December 31, 2020:

Amortization  for  Aptevo  BioTherapeutics  was  $0.1  million  and  $0.8  million  for  the  year  ended  December  31,  2020  and  December  31,  2019,
respectively. There was no depreciation or capital expenditures for the year ended December 31, 2020 or December 31, 2019. Significant operating non-
cash items include the gain on sale of Aptevo BioTherapeutics of $14.3 million for the year ended December 31, 2020, and the gain on milestone payment
related to the sale of the Hyperimmune business of $4.3 million for the year ended December 31, 2019. There were no significant investing non-cash items
for the years ended December 31, 2019 and 2020.

Medexus reported their net IXINITY sales to Aptevo and made a deferred payment to Aptevo of $0.4 million for the first three quarters of 2020.
As such, we recorded the deferred payment amount related to Medexus’ sales of IXINITY as a gain when collected. Subsequent to year end, Medexus
made a deferred payment of approximately $0.2 million, related to fourth quarter 2020 IXINITY sales.    

Note 3. Collaboration Agreements

Alligator

On July 20, 2017, our wholly owned subsidiary Aptevo Research and Development LLC (Aptevo R&D), entered into a collaboration and option
agreement (the Collaboration Agreement) with Alligator Bioscience AB (Alligator), pursuant to which Aptevo and Alligator will collaboratively develop
ALG.APV-527,  a  lead  bispecific  antibody  candidate  simultaneously  targeting  4-1BB  (CD137),  a  member  of  the  TNFR  superfamily  of  a  costimulatory
receptor found on activated T-cells, and 5T4, a tumor antigen widely overexpressed in a number of different types of cancer.

We assessed the arrangement in accordance with ASC 606 and concluded that the contract counterparty, Alligator, is not a customer. As such the
arrangement is not in the scope of ASC 606 and is instead treated as a collaborative agreement under ASC 808 – Collaborative Arrangements (ASC 808).
In accordance with ASC 808, we concluded that because the Collaboration Agreement with Alligator is a cost sharing agreement, there is no revenue.

For the year ended December 31, 2020, we recorded an immaterial amount in our research and development expense in the consolidated statements
of  operations,  and  for  the  year  ended  December  31,  2019,  we  recorded  a  reduction  of  $1.4  million  in  our  research  and  development  expense  in  the
consolidated statements of operations, related to the collaboration arrangement.  

Note 4. Fair Value Measurements

The  Company’s  estimates  of  fair  value  for  financial  assets  and  financial  liabilities  are  based  on  the  framework  established  in  the  fair  value
accounting guidance. The framework is based on the inputs used in valuation, gives the highest priority to quoted prices in active markets and requires that
observable inputs be used in the valuations when available. The disclosure of fair value estimates in the fair value accounting guidance hierarchy is based
on whether the significant inputs into the valuation are observable. In determining the level of the hierarchy in which the estimate is disclosed, the highest
priority is given to unadjusted quoted prices in active markets and the lowest priority to unobservable inputs that reflect the Company’s significant market
assumptions. The level in the fair value hierarchy within which the fair value measurement is reported is based on the lowest level input that is significant
to the measurement in its entirety. The three levels of the hierarchy are as follows:

Level 1— Observable inputs of quoted prices in active markets for identical assets and liabilities;

Level 2— Inputs other than quoted prices in active markets, that are either directly or indirectly observable; and,

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.

At December 31, 2020 and December 31, 2019, we had $35.4 million and $12.5 million in money market funds, respectively. Money market funds
are  level  one  balances  as  they  are  valued  at  fair  value,  which  is  the  closing  price  reported  by  the  fund  sponsor  from  an  actively  traded  exchange.  At
December 31, 2020 and December 31, 2019, we did not have any level two or level three assets or liabilities.

Note 5. Cash, Cash Equivalents, and Restricted Cash

The Company’s cash equivalents are highly liquid investments with a maturity of 90 days or less at the date of purchase and include time deposits

and investments in money market funds. Restricted cash, current includes $2.6 million securing letters of credit.

The  following  table  shows  our  cash,  cash  equivalents  and  restricted  cash,  both  current  and  long-term  portion  as  of  December  31,  2020  and

Note 7. Debt

Credit Agreement

On August 4, 2016, we entered into a Credit and Security Agreement (the Prior Credit Agreement), with MidCap Financial. On February 28, 2020,
we  repaid  the  entire  amount  outstanding  under  the  Prior  Credit  Agreement  from  the  proceeds  of  the  sale  of  Aptevo  BioTherapeutics  to  Medexus.    In
addition to the outstanding principal of $20 million, we paid $2.1 million in an end of facility fee, accrued interest, legal fees and prepayment fees. We
recorded an adjustment of $0.1 million related to unamortized loan initiation fees and a $2.1 million loss on extinguishment of debt in the first quarter of
2020.

On August 5, 2020, we entered into a new Credit and Security Agreement (the Credit Agreement), with MidCap Financial. The Credit Agreement
provided us with up to $25 million of available borrowing capacity under a term loan facility. The full $25 million was drawn on the closing date of the
Credit Agreement. The term loan facility has a 48 month term, is interest-only for the first 18 months, with straight-line amortization for the remaining 30
months and bears interest at a rate of one month LIBOR plus 6.25% per annum, subject to a 1.50% LIBOR floor and a 2.50% LIBOR cap. The term loan
facility includes additional repayment provisions should either or both of the royalties or milestones related to IXINITY or royalties related to RUXIENCE
be sold during the term of the loan.

As  of  December  31,  2020,  we  reclassified  $5.0  million  of  the  $25  million  Credit  Agreement  to  current  portion  of  long-term  debt  on  the
consolidated balance sheet. The Credit Agreement states that commencing with the calendar quarter ending June 30, 2021 and for each calendar quarter
thereafter, Aptevo will prepay the Term Loan in an amount equal to 100% of the royalties received from RUXIENCE and IXINITY within 45 days of
quarter-end,  up  to  $2.5  million  each  quarter.  We  expect  to  prepay  $5.0  million  of  the  Term  Loan  principal  in  2021  and  reclassified  this  portion  of  the
principal to current portion of long-term debt on the consolidated balance sheet.

On November 6, 2020, Tang filed a statement on Schedule 13D to report that Tang had purchased 1,760,000 shares of the Company’s common
stock, which at the time represented approximately 54% of the Company’s issued and outstanding shares of the Company’s common stock. This acquisition
of voting stock triggered a change in control, resulting in an Event of Default under Section 10.1(a)(ii) of the Credit Agreement. On November 10, 2020,
the Company obtained a waiver from MidCap Financial pursuant to which, among other things, MidCap Financial waived the event of default arising from
the acquisition of voting stock by Tang and MidCap Financial and the Company agreed that an immediate event of default under the Credit Agreement will
be deemed to have occurred in the event that (a) a majority of the seats on the Company’s board of directors are occupied by persons who were neither (i)
nominated by the Company’s board of directors nor (ii) appointed by the directors so nominated, and (b) Tang has appointed the majority of the Company’s
board of directors. No other events of default have occurred with respect to the Company’s credit agreement.

Additionally, this facility is subject to a subjective acceleration clause that could be invoked by the lender upon the occurrence of any event the

lender deems to have a material adverse effect on our ability to repay the lender.

Note 8. Leases and Contingencies

Office Space Lease – Operating

We have an operating lease related to our office and laboratory space in Seattle, Washington. This lease was amended and extended in March 2019.
The term of the amended lease is through April 2030 and we have two options to extend the lease term, each by five years, as well as a one-time option to
terminate the lease in April 2023. The lease was further amended, effective August 2019, to reduce the square footage of our rented area.  

 The amended lease has a renewal option of two five-year renewals at fair market value as determined at the time of renewal, and a termination
option after month thirty-six with nine months written notice. The termination option also requires a penalty equal to the unamortized tenant improvement
allowance  at  8%  interest,  the  unamortized  real  estate  taxes  at  8%  interest,  and  the  equivalent  of  four-months’  rent  at  the  base  rent  price  at  the  time  of
termination.  The  estimated  termination  penalty  has  been  recorded  in  our  lease  payments.  We  determined  we  should  not  include  any  periods  after  the
termination option when evaluating this amendment as we are not reasonably certain to not exercise the option, therefore we are recording our liability
through April 30, 2023.

For  the  years  ended  December  31,  2020  and  December  31,  2019,  we  recorded  $0.7  million  and  $0.5  million,  respectively,  related  to  variable

expenses due to true ups of operating costs or real estate taxes.

 Equipment Leases - Operating

As of December 31, 2020, we have operating leases for one piece of lab equipment and four copiers in our Seattle, Washington headquarters. The

future expense for these leases will be straight-line and will include any variable expenses that arise.

Equipment Lease – Financing

As of December 31, 2020, we had one equipment lease classified as a financing lease as the lease transferred ownership of the underlying asset to
us  at  the  end  of  the  lease  term  in  2020.  The  lease  has  no  remaining  expense  obligation.  There  were  no  financing  lease  payments  for  the  year  ended
December 31, 2020.

The long-term portion of the lease liabilities included in the amounts above is $2.4 million and the remainder of our lease liabilities are included in

other current liabilities on our consolidated balance sheets.

As of December 31, 2020, the weighted average remaining lease term and weighted discount rate for operating leases was 2.3 years and 14.52%.

As of December 31, 2019, the weighted average remaining lease term and weighted discount rate for operating leases was 3.3 years and 14.55%.

Note 9. Reverse Stock Split

On  March  11,  2020,  we  held  a  Special  Meeting  of  Stockholders  at  which  our  stockholders  approved  a  series  of  alternate  amendments  to  the
Amended and Restated Certificate of Incorporation to effect, at the option of our Board of Directors, a reverse split of Aptevo’s common stock at a ratio
ranging  from  1-for-2  to  1-for-20,  inclusive,  with  the  effectiveness  of  one  of  such  amendments  and  the  abandonment  of  the  other  amendments,  or  the
abandonment of all amendments, to be determined by the Board in its sole discretion following the Special Meeting. The specific 1-for-14 reverse split
ratio was subsequently approved by the Board on March 23, 2020. On March 26, 2020, the Company filed a Certificate of Amendment of Amended and
Restated Certificate of Incorporation (the “Amendment”) with the Secretary of State of the State of Delaware to effect a 1-for-14 reverse stock split of the
Company’s outstanding common stock.

No fractional shares were issued as a result of the reverse stock split. Stockholders of record who would otherwise be entitled to receive a fractional

share received a cash payment in lieu thereof. 

We have adjusted all common stock and stock equivalent figures retroactively in this Form 10-K for all periods presented to reflect the reverse

stock split.

Note 10. Net Income (Loss) per Share

Basic  net  loss  per  share  is  calculated  by  dividing  the  net  loss  by  the  weighted  average  number  of  common  shares  outstanding  for  the  period.
Diluted net loss per share is computed by dividing the net loss by the weighted average number of common share equivalents outstanding for the period
using the as-if converted method. For the purpose of this calculation, warrants, stock options and restricted stock units (RSUs) are only included in the
calculation of diluted net income per share when their effect is dilutive.

We utilize the control number concept in the computation of diluted earnings per share to determine whether potential common stock instruments
are dilutive. The control number used is loss from continuing operations or income from discontinued operations. The control number concept requires that
the  same  number  of  potentially  dilutive  securities  applied  in  computing  diluted  earnings  per  share  from  continuing  operations  be  applied  to  all  other
categories of income or loss, regardless of their anti-dilutive effect on such categories. Therefore, no dilutive effect has been recognized in the calculation
of income from discontinued operations per share.

Common stock equivalents include warrants, stock options and unvested RSUs.

The following table presents the computation of basic and diluted net loss per share (in thousands, except share and per share amounts):

On March 11, 2019, we completed a public offering of common stock and warrants, as follows:

•

•

for a combined public offering price of $14.00 per share of common stock and related warrants, 1,417,857 shares of common stock and
related warrants with a 5-year life to purchase up to 1,417,857 shares of common stock at an exercise price of $18.20 per share,

for  a  combined  public  offering  price  of  $13.86  per  pre-funded  warrant  and  related  warrant,  pre-funded  warrants  with  a  10-year  life  to
purchase up to 153,571 shares of common stock at an exercise price of $0.14 per share and related warrants with a 5-year life to purchase
up to 153,571 shares of common stock at an exercise price of $18.20 per share. These pre-funded warrants were exercised on March 21,
2019.

We received net proceeds of $20.2 million, net of transaction costs, as a result of this offering.

For the year ended December 31, 2020, certain of the holders of the Company’s warrants exercised warrants with a strike price of $18.20 per share,
resulting  in  the  issuance  of  approximately  1,166,735  million  shares  of  the  Company’s  common  stock  and  aggregate  proceeds  to  the  Company  of
approximately $21.2 million. As of December 31, 2020, there were 404,694 warrants outstanding.

For the years ended December 31, 2020 and December 31, 2019, we issued 9,206 and 6,752 shares of common stock due to the vesting of RSUs,

respectively.

For the year ended December 31, 2020, we received proceeds of $0.02 million upon the exercise of stock options which resulted in the issuance of

2,158 shares of common stock.

Purchase Agreement

On December 20, 2018, we entered into the Purchase Agreement, and a registration rights agreement, with Lincoln Park. Pursuant to the purchase
agreement, Lincoln Park has committed to purchase up to $35.0 million worth of our common stock over a 36-month period commencing on February 13,
2019,  the  date  the  registration  statement  covering  the  resale  of  the  shares  was  declared  effective  by  the  SEC.  Under  the  Purchase  Agreement,  on  any
business day selected by us, we may direct Lincoln Park to purchase shares of our common stock provided that Lincoln Park’s maximum commitment on
any single day does not exceed $2.0 million. The purchase price per share will be based off of prevailing market prices of our common stock immediately
preceding the time of sale; provided, however, that we cannot direct any such purchase if the prevailing market price is less than $1.00. Pursuant to this
purchase agreement we issued 13,990 commitment shares of common stock in the first quarter of 2019 and none in the year ended December 31, 2020.

Rights Plan

On November 8, 2020, the Board approved and adopted a Rights Agreement, dated as of November 8, 2020, by and between the Company and
Broadridge Corporate Issuer Solutions, Inc., as rights agent, pursuant to which the Board declared a dividend of one preferred share purchase right (each, a
Right)  for  each  outstanding  share  of  the  Company’s  common  stock  held  by  stockholders  as  of  the  close  of  business  on  November  23,  2020.    When
exercisable, each right initially would represent the right to purchase from the Company one one-thousandth of a share of a newly-designated series of
preferred stock, Series A Junior Participating Preferred Stock, par value $0.001 per share, of the Company, at an exercise price of $400.00 per one one-
thousandth of a Series A Junior Participating Preferred Share, subject to adjustment. Subject to various exceptions, the Rights become exercisable in the
event any person (excluding certain exempted or grandfathered persons) becomes the beneficial owner of ten percent (10%) or more of the Company’s
common stock without the approval of the Board.

Equity Distribution Agreement

On  December  14,  2020  we  entered  into  an  Equity  Distribution  Agreement  (the  Equity  Distribution  Agreement)  with  Piper  Sandler.  The  Equity
Distribution Agreement provides that, upon the terms and subject to the conditions set forth therein, we may issue and sell through Piper Sandler, acting as
sales agent, shares of our common stock, $0.001 par value per share, having an aggregate offering price of up to $50 million. This offering supersedes and
replaces the program we commenced in December 2017. We have no obligation to sell any such shares under the Equity Distribution Agreement. The sale
of such shares of common stock by Piper Sandler will be effected pursuant to a Registration Statement on Form S-3, which we filed on December 14, 2020.
We issued no shares under the Equity Distribution Agreement in 2020.

Converted Equity Awards Incentive Plan

In connection with the spin-off from Emergent BioSolutions Inc. (Emergent) in August 2016, we adopted the Converted Equity Awards Incentive
Plan (the Converted Plan). Under the Converted Plan, outstanding equity awards of Emergent held by Aptevo employees were converted into or replaced
with  equity  awards  of  Aptevo  (Conversion  Awards)  and  were  adjusted  to  maintain  the  economic  value  before  and  after  the  distribution  date,  using  the
relative fair market value of the Emergent and Aptevo common stock based on the closing prices as of August 1, 2016. A total of 0.1 million shares of
Aptevo common stock have been authorized for issuance under the Converted Plan. Options issued as Conversion Awards were priced according to the
Converted Plan. RSUs issued as part of the Converted Plan provide for the issuance of a share of Aptevo’s stock at no cost to the holder.

83

 
 
2016 Stock Incentive Plan

On August 1, 2016, the Company adopted the 2016 Stock Incentive Plan (the 2016 SIP). A total of 0.2 million shares of Aptevo common stock

have been authorized for issuance under the 2016 SIP in the form of equity stock options.

Stock options under the 2016 SIP generally vest pro rata over a three-year period and terminate ten years from the grant date, though the specific
terms  of  each  grant  are  determined  individually.  The  Company’s  executive  officers  and  certain  other  employees  may  be  awarded  options  with  different
vesting criteria, and options granted to non-employee directors also vest over a three-year period. Option exercise prices for new options granted by the
Company equal the closing price of the Company’s common stock on the Nasdaq Capital Market on the date of grant.

RSUs issued under the 2016 SIP provide for the issuance of a share of the Company’s common stock at no cost to the holder. RSUs granted to
employees  under  the  2016  SIP  generally  provide  for  time-based  vesting  over  a  twelve-month  to  three-year  period,  although  certain  employees  may  be
awarded RSUs with different time-based vesting criteria. Prior to vesting, RSUs granted under the 2016 SIP do not have dividend equivalent rights, do not
have voting rights and the shares underlying the RSUs are not considered issued or outstanding.

The  equity  compensation  awards  granted  by  the  Company  generally  vest  only  if  the  employee  is  employed  by  the  Company  (or  in  the  case  of

directors, the director continues to serve on the Board) on the vesting date.

On May 31, 2017, at the Annual Meeting of Stockholders (Annual Meeting) in 2017, the Company’s stockholders approved the amendment and
restatement of the Company’s 2016 SIP (the Restated 2016 Plan) to, among other things, increase the number of authorized shares issuable by 0.1 million
shares  of  Aptevo  common  stock.  The  Restated  2016  Plan  was  previously  approved,  subject  to  stockholder  approval,  by  the  Board  of  Directors  of  the
Company.

2018 Stock Incentive Plan

On  June  1,  2018,  at  the  2018  Annual  Meeting,  the  Company’s  stockholders  approved  a  new  2018  Stock  Incentive  Plan  (the  2018  SIP),  which
replaced the Restated 2016 Plan on a go-forward basis. All stock options, RSUs or other equity awards granted subsequent to June 1, 2018, will be issued
out  of  the  2018  SIP,  which  has  0.3  million  shares  of  Aptevo  common  stock  authorized  for  issuance. The  2018  SIP  became  effective  immediately  upon
stockholder approval at the Annual Meeting. Any shares subject to outstanding stock awards granted under the 2016 SIP that (a) expire or terminate for any
reason prior to exercise or settlement; (b) are forfeited because of the failure to meet a contingency or condition required to vest such shares or otherwise
return  to  the  Company;  or  (c)  otherwise  would  have  returned  to  the  2016  SIP  for  future  grant  pursuant  to  the  terms  of  the  2016  SIP  (such  shares,  the
“Returning  Shares”)  will  immediately  be  added  to  the  share  reserve  under  the  2018  SIP  as  and  when  such  shares  become  Returning  Shares,  up  to  a
maximum of 0.3 million shares. The 2018 SIP was previously approved, subject to stockholder approval, by the Board of Directors of the Company. As of
December 31, 2020, there are 0.3 million shares available to be granted under the 2018 SIP.

Stock options under the 2018 SIP generally vest pro rata over a three-year period and terminate ten years from the grant date, though the specific
terms  of  each  grant  are  determined  individually.  The  Company’s  executive  officers  and  certain  other  employees  may  be  awarded  options  with  different
vesting criteria, and options granted to non-employee directors also vest over a three-year period. Option exercise prices for new options granted by the
Company equal the closing price of the Company’s common stock on the Nasdaq Capital Market on the date of grant.

Stock-Based Compensation Expense

granted based on the fair value of the award as of the grant date. The Company recognizes the compensation expense over the vesting period.

Stock Option Exchange

On June 29, 2020, Aptevo commenced a voluntary employee and directors stock option exchange program (the Exchange Program) to permit the
Company’s  eligible  employees,  directors  and  certain  consultants  to  exchange  some  or  all  of  their  eligible  outstanding  options  (Original  Options)  to
purchase the Company’s common stock with an exercise price greater than or equal to $21.00 per share, whether vested or unvested, for a lesser number of
new stock options (New Options) with an exercise price equal to $8.56, which was the closing price of our stock on July 27, 2020. In accordance with the
terms  and  conditions  of  the  Exchange  Program,  we  closed  the  exchange  program  and  accepted  all  exchanged  outstanding  Original  Options  for  New
Options on July 27, 2020. The stock option exchange program was approved at the Company’s 2020 Annual Shareholder Meeting on May 27, 2020.

Pursuant to the Exchange Offer, 52 Eligible Holders elected to exchange Original Options, and the Company accepted for cancellation Original
Options  to  purchase  an  aggregate  of  200,016  shares  of  the  Company’s  common  stock,  representing  approximately  96%  of  the  total  shares  of  Common
Stock underlying the Eligible Options. On July 27, 2020, immediately following the expiration of the Exchange Offer, the Company granted New Options
to  purchase  84,900  shares  of  Common  Stock,  pursuant  to  the  terms  of  the  Exchange  Offer  and  the  2018  SIP.  We  recorded  an  immaterial  additional
compensation cost related to the exchange, as the estimated fair value of the new options slightly exceed the fair value of the exchanged stock options
calculated  immediately  prior  to  the  exchange.  We  recognized  $0.04  million  for  the  remaining  unamortized  compensation  cost  related  to  the  exchanged
options in the third quarter of 2020.

Stock Options

Aptevo utilizes the Black-Scholes valuation model for estimating the fair value of all stock options granted. Set forth below are the assumptions

used in valuing the stock options granted:

Expected dividend yield
Expected volatility
Risk-free interest rate
Expected average life of options

For the Year Ended December 31,

87.78%
1.97%

2.04%
5 years

Management has applied an estimated forfeiture rate of 16% and 10% for the year ended December 31, 2020 and December 31, 2019, respectively.
Expected  volatility  increased,  as  our  stock  price  fluctuated  from  a  low  of  $3.11  to  a  high  of  $48.36  throughout  the  year  ended  December  31,  2020,
compared to a low of $7.36 and high of $26.18 for the year ended December 31, 2019. The increase in expected average life of options is due to the impact
of the option exchange program, which concluded on July 27, 2020, as new options were issued with an expiration of July 26, 2030.

As of December 31, 2020 we had $1.0 million of unrecognized compensation expense related to options expected to vest over a weighted average
period of 1.2 years. The weighted average remaining contractual life of outstanding and exercisable options is 7.4 years. The 325,904 shares forfeited in the
year ended December 31, 2020, are primarily related to the 200,016 options forfeited as part of the option exchange program, which concluded on July 27,
2020.

The  aggregate  intrinsic  value  in  the  table  above  represents  the  total  pretax  intrinsic  value  (the  difference  between  the  closing  stock  price  of
Aptevo’s common stock on the last trading day of 2020 and the exercise price, multiplied by the number of in the money options) that would have been
received by the option holders had all the option holders exercised their options on December 31, 2020.

The fair value of each RSU has been determined to be the closing trading price of the Company’s common shares on the date of grant as quoted in

The Nasdaq Capital Market.

Warrants

In March 2019, as part of a public offering, we issued warrants to purchase up to 1,725,000 shares of our common stock, 1,571,429 of which have
an exercise price of $18.20 per share and have a five-year life, and 153,571 of pre-funded warrants with an exercise price of $0.14 per share. The pre-
funded  warrants  had  a  ten-year  life  and  would  have  expired  on  March  11,  2029;  however,  the  pre-funded  warrants  were  exercised  in  March  2019.  We
determined  the  warrants  do  not  meet  liability  classification  pursuant  to  ASC  480  –  Distinguishing  Liabilities  from  Equity.  They  are  therefore  included
within equity on our consolidated balance sheets. In the fourth quarter of 2020, certain holders of the Company’s warrants exercised warrants with a strike
price of $18.20 per share, resulting in the issuance of approximately 1,166,735 million shares of the Company’s common stock and aggregate proceeds to
the Company of approximately $21.2 million. As of December 31, 2020, there were 404,694 warrants outstanding.

Note 12. 401(k) Savings Plan

Aptevo  has  established  a  defined  contribution  savings  plan  under  Section  401(k)  of  the  Internal  Revenue  Code,  as  amended.  The  401(k)  Plan
covers all employees. Under the 401(k) Plan, employees may make elective salary deferrals. Aptevo currently provides for matching of qualified deferrals
up  to  50%  of  401(k)  employee  deferral  contributions,  based  on  a  maximum  employee  deferral  rate  of  6%  of  compensation.  During  the  year  ended
December  31,  2020  and  December  31,  2019,  Aptevo’s  related  share  of  matching  contributions  was  approximately  $0.3  million  and  $0.4  million,
respectively.

As  of  December  31,  2020,  and  2019,  we  have  recorded  federal  net  operating  losses  (NOL)  carryforwards  of  approximately  $162.5  million  and
$134.4 million, state NOL carryforwards of approximately $68.1 million and $59.4 million, and tax credit carryforwards of $2.2 million and $1.4 million,
respectively. $40.9 million of the federal losses and credits would begin to expire in 2037, while $121.6 million of federal losses may be carried forward
indefinitely. The state net operating losses will begin to expire in varying periods.

The Company is in the process of completing an IRC Section 382/383 study on its federal and state tax attributes based on an ownership change
that occurred during 2020. At this time the Company does not anticipate any permanent limitations on our ability to use federal and state net operating loss
carryforwards and tax credits. We may experience ownership changes in the future as a result of subsequent shifts in our stock ownership, some of which
may be outside of our control. If an ownership change occurs in the future, our ability to use our net operating loss carryforwards and credits could be
limited.

The  Company  files  income  tax  returns  in  the  U.S.  and  several  state  jurisdictions  and  are  open  to  review  by  taxing  authorities  for  the  2016  tax

filings and thereafter.

We  are  subject  to  the  accounting  guidance  for  uncertain  income  tax  positions.  We  believe  that  our  income  tax  positions  and  deductions  will  be
sustained on audit and do not anticipate any adjustments that will result in a material adverse effect on our financial condition, results of operations, or cash
flow. Our policy for recording interest and penalties associated with audits and uncertain tax positions is to record such items as a component of income tax
expense, and amounts recognized to date are insignificant. No uncertain income tax positions are recorded, and we do not expect our uncertain tax position
to change during the next twelve months.

The reconciliation of the federal statutory income tax rate to the Company’s effective income tax from continuing operations is as follows:

Federal tax at statutory rates
State taxes, net of federal benefit
Change in valuation allowance
Tax credits
Permanent differences
Other
Total income tax benefit

On  March  3,  2021  the  Company  collected  $0.3  million  related  to  the  sale  of  the  Hyperimmune  Busines  to  Saol  and  the  collection  of  certain

accounts receivable.

On March 19, 2021, $1.3 million of the restricted cash securing letters of credit was released in Aptevo’s favor.

On March 30, 2021, the Company entered into and closed a royalty purchase agreement (the Royalty Purchase Agreement) with an entity managed
by HealthCare Royalty Management, LLC (HCR) pursuant to which the Company sold to HCR the right to receive all royalty payments made by Pfizer
Inc.  (Pfizer)  in  respect  of  net  sales  of  RUXIENCE.  Under  the  terms  of  the  agreement,  the  Company  received  $35  million  (the  Investment  Amount)  at
closing and the Company is eligible to receive additional payments in aggregate of up to an additional $32.5 million based on the achievement of sales
milestones  in  2021,  2022,  and  2023  (collectively,  the  Milestone  Amounts).  The  Royalty  Purchase  Agreement  further  provides  that,  once  HCR  reaches
aggregate royalty payments totaling 190% of the Investment Amount plus the Milestone Amounts to the extent paid by HCR to the Company, Aptevo will
be entitled to receive 50% of royalty interest payments thereafter.

In connection with the Royalty Purchase Agreement, the Company amended its Credit Agreement with MidCap Financial and used $10 million of
the proceeds received from the Royalty Purchase Agreement with HCR to pay down the outstanding principal under this agreement from $25 million to
$15 million. $10 million of the remaining $15 million principal balance will be payable on March 31, 2022.  Beginning March 1, 2022, monthly repayment
of the remaining $5 million of principal will commence and continue for the final 30 months of the loan term. If the Company sells the IXINITY deferred
payment stream and milestones prior to full repayment of this $5 million principal amount, under the agreement with MidCap Financial, proceeds from
same will be applied to pay down the outstanding loan principal balance. MidCap Financial also released its security interest in the RUXIENCE royalty
payments. A fee of $550,000 was paid by the Company to MidCap Financial in connection with the amendment in lieu of the formula-based fee previously
required.

Item 9A. Controls and Procedures.

Evaluation of Disclosure Controls and Procedures

As of December 31, 2020, management, with the participation of our Chief Executive Officer and Chief Financial Officer, performed an evaluation
of the effectiveness of our disclosure controls and procedures as defined in Rules 13a- 15(e) and 15d-15(e) of the Exchange Act. Based on this evaluation,
our Chief Executive Officer and Chief Financial Officer concluded that, as of December 31, 2020, the design and operation of our disclosure controls and
procedures were effective to provide reasonable assurance that information we are required to disclose in reports that we file or submit under the Exchange
Act is recorded, processed, summarized, and reported within the time periods specified in the SEC’s rules and forms and to provide reasonable assurance
that  such  information  is  accumulated  and  communicated  to  our  management,  including  our  Chief  Executive  Officer  and  Chief  Financial  Officer,  as
appropriate to allow timely decisions regarding required disclosure.

Management’s Report on Internal Control over Financial Reporting

Management is responsible for establishing and maintaining adequate internal control over financial reporting, as defined in Rule 13a-15(f) of the
1934 Act. Management has assessed the effectiveness of our internal control over financial reporting as of December 31, 2020 based on criteria established
in Internal Control—Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission. As a result of this
assessment,  management  concluded  that,  as  of  December  31,  2020,  our  internal  control  over  financial  reporting  was  effective  in  providing  reasonable
assurance  regarding  the  reliability  of  financial  reporting  and  the  preparation  of  financial  statements  for  external  purposes  in  accordance  with  generally
accepted accounting principles.

Changes in Internal Control over Financial Reporting

There have been no changes in our internal control over financial reporting (as defined in Rules 13a-15(f) and 15d-15(f) under the Exchange Act)
during the year ended December 31, 2020, that have materially affected, or are reasonably likely to materially affect, our internal control over financial
reporting.

Limitations on Controls

Because of inherent limitations, disclosure controls and 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.

DESCRIPTION OF THE REGISTRANT’S SECURITIES
REGISTERED PURSUANT TO SECTION 12 OF THE
SECURITIES EXCHANGE ACT OF 1934

Exhibit 4.5

The following description of the common stock, par value $0.001 per share (the “common stock”), of Aptevo Therapeutics Inc. (“us,” “our,”
“we” or the “Company”), which is the only security of the Company registered under Section 12 of the Securities Exchange Act of 1934, as amended (the
“Exchange Act”), summarizes certain information regarding the common stock in our amended and restated certificate of incorporation, our amended and
restated  bylaws,  applicable  provisions  of  the  Delaware  General  Corporation  Law  (the  “DGCL”)  and  pursuant  to  our  rights  plan,  and  is  qualified  by
reference to our amended and restated certificate of incorporation, amended and restated bylaws and rights agreement, which are incorporated by reference
as Exhibit 3.1, Exhibit 3.2, and Exhibit 4.4 respectively, to our Annual Report on Form 10-K of which this Exhibit 4.5 is a part.

Authorized Capital Stock

Our authorized capital stock consists of 500,000,000 shares of common stock and 15,000,000 shares of preferred stock, $0.001 par value per
share (the “preferred stock”). Our common stock is registered under Section 12(b) of the Exchange Act and is listed on the Nasdaq Capital Market under
the trading symbol “APVO.”

Common Stock

Voting Rights

Each holder of our common stock is entitled to one vote for each share on all matters submitted to a vote of the stockholders, including the
election  of  directors.  Under  our  amended  and  restated  certificate  of  incorporation  and  amended  and  restated  bylaws,  our  stockholders  do  not  have
cumulative voting rights. Because of this, the holders of a majority of the shares of common stock entitled to vote in any election of directors can elect all
of the directors standing for election, if they should so choose.

Dividends

Subject to preferences that may be applicable to any then-outstanding shares of preferred stock, holders of common stock are entitled to receive

ratably those dividends, if any, as may be declared from time to time by our board of directors out of legally available funds.

Liquidation

In the event of our liquidation, dissolution or winding up, holders of common stock will be entitled to share ratably in the net assets legally
available for distribution to stockholders after the payment of all of our debts and other liabilities and the satisfaction of any liquidation preference granted
to the holders of any then-outstanding shares of preferred stock.

Rights and Preferences

Each  share  of  common  stock  includes  an  associated  right  pursuant  to  and  as  set  forth  in  the  Rights  Agreement  that  we  entered  into  with
Broadridge Corporate Issuer Solutions, Inc. on November 8, 2020 (the “rights agreement”). Each right initially represents the right to purchase from us one
one-thousandth of a share of our Series A Junior Participating Preferred Stock, par value $0.001 per share. This right is not exercisable until the occurrence
of certain events specified in such rights agreement. The value attributable to these rights, if any, is reflected in the value of our common stock. The rights
agreement and the rights granted thereunder will expire upon the earliest to occur of (i) the

 
 
date on which all of such rights are redeemed, (ii) the date on which such rights are exchanged, and (iii) the close of business on November 8, 2021.

Fully Paid and Nonassessable.

All of our outstanding shares of common stock are fully paid and nonassessable.

Preferred Stock

Pursuant  to  our  amended  and  restated  certificate  of  incorporation,  our  board  of  directors  has  the  authority,  without  further  action  by  our
stockholders, to designate up to 15,000,000 shares of preferred stock in one or more series and to fix the rights, preferences, privileges and restrictions
thereof.  These  rights,  preferences  and  privileges  could  include  dividend  rights,  conversion  rights,  voting  rights,  terms  of  redemption,  liquidation
preferences, sinking fund terms and the number of shares constituting, or the designation of, such series, any or all of which may be greater than the rights
of common stock.

The DGCL provides that the holders of preferred stock will have the right to vote separately as a class on any proposal involving fundamental
changes in the rights of holders of that preferred stock. This right is in addition to any voting rights that may be provided for in the applicable certificate of
designation.

Certain Anti-Takeover Provisions of Our Certificate of Incorporation, Our Bylaws, the DGCL and our Rights Plan

Delaware Law

We  are  subject  to  Section  203  of  the  DGCL,  which  prohibits  a  Delaware  corporation  from  engaging  in  any  business  combination  with  any

interested stockholder for a period of three years after the date that such stockholder became an interested stockholder, with the following exceptions:

•

•

•

before such date, the board of directors of the corporation approved either the business combination or the transaction that resulted in the
stockholder becoming an interested stockholder;

upon completion of the transaction that resulted in the stockholder becoming an interested stockholder, the interested stockholder owned
at least 85% of the voting stock of the corporation outstanding at the time the transaction began, excluding for purposes of determining
the voting stock outstanding (but not the outstanding voting stock owned by the interested stockholder) those shares owned (1) by persons
who  are  directors  and  also  officers  and  (2)  employee  stock  plans  in  which  employee  participants  do  not  have  the  right  to  determine
confidentially whether shares held subject to the plan will be tendered in a tender or exchange offer; or

on or after such date, the business combination is approved by the board of directors and authorized at an annual or special meeting of the
stockholders, and not by written consent, by the affirmative vote of at least 66 2/3% of the outstanding voting stock that is not owned by
the interested stockholder.

In general, Section 203 defines a “business combination” to include the following:

•

•

•

•

•

any merger or consolidation involving the corporation and the interested stockholder;

any sale, transfer, pledge or other disposition of 10% or more of the assets of the corporation involving the interested stockholder;

subject to certain exceptions, any transaction that results in the issuance or transfer by the corporation of any stock of the corporation to
the interested stockholder;

any transaction involving the corporation that has the effect of increasing the proportionate share of the stock or any class or series of the
corporation beneficially owned by the interested stockholder; or

the receipt by the interested stockholder of the benefit of any loans, advances, guarantees, pledges or other financial benefits by or
through the corporation.

 
 
 
 
 
 
 
 
 
 
In  general,  Section  203  defines  an  “interested  stockholder”  as  an  entity  or  person  who,  together  with  the  person’s  affiliates  and  associates,
beneficially owns, or within three years prior to the time of determination of interested stockholder status did own, 15% or more of the outstanding voting
stock of the corporation.

Staggered Board; Removal of Directors

Our amended and restated certificate of incorporation provides for our board of directors to be divided into three classes with staggered three-
year terms. Only one class of directors is elected at each annual meeting of our stockholders, with the other classes continuing for the remainder of their
respective three-year terms. Because our stockholders do not have cumulative voting rights, stockholders holding a majority of the shares of common stock
outstanding  are  able  to  elect  all  of  our  directors.  Our  certificate  of  incorporation  and  our  bylaws  also  provide  that  directors  may  be  removed  by  the
stockholders only for cause upon the vote of 75% of our outstanding common stock. Furthermore, the authorized number of directors may be changed only
by resolution of the board of directors, and vacancies and newly created directorships on the board of directors may, except as otherwise required by law or
determined by the board, only be filled by a majority vote of the directors then serving on the board, even though less than a quorum.

Stockholder Action by Written Consent.

Our  amended  and  restated  certificate  of  incorporation  and  amended  and  restated  bylaws  also  provide  that  all  stockholder  actions  must  be
effected at a duly called meeting of stockholders and eliminates the right of stockholders to act by written consent without a meeting. Our amended and
restated bylaws also provide that only our chairman of the board, chief executive officer or the board of directors pursuant to a resolution adopted by a
majority of the total number of authorized directors may call a special meeting of stockholders.

Requirements for Advance Notification of Stockholder Nominations, Proposals and Amendments.

Our amended and restated bylaws also provide that stockholders seeking to present proposals before a meeting of stockholders to nominate
candidates for election as directors at a meeting of stockholders must provide timely advance notice in writing, and specify requirements as to the form and
content of a stockholder’s notice. Our certificate of incorporation and bylaws provide that the stockholders cannot amend many of the provisions described
above except by a vote of 75% or more of our outstanding common stock.

Shareholder Rights Plan

On  November  8,  2020,  our  board  of  directors  adopted  a  rights  plan  pursuant  to  our  rights  agreement.  The  rights  plan  works  by  causing
substantial dilution to any person or group that acquires beneficial ownership of ten percent (10%) or more of our common stock without the approval of
our board of directors. As a result, the overall effect of the rights plan and the issuance of the rights pursuant to the rights plan may be to render more
difficult  or  discourage  a  merger,  tender  or  exchange  offer  or  other  business  combination  involving  the  Company  that  is  not  approved  by  our  board  of
directors. The rights plan is not intended to interfere with any merger, tender or exchange offer or other business combination approved by our board of
directors.  The  rights  plan  also  does  not  prevent  our  board  of  directors  from  considering  any  offer  that  it  considers  to  be  in  the  best  interest  of  our
stockholders.

These provisions are intended to enhance the likelihood of continued stability in the composition of our board of directors and its policies and
to discourage coercive takeover practices and inadequate takeover bids. These provisions are also designed to reduce our vulnerability to hostile takeovers
and  to  discourage  certain  tactics  that  may  be  used  in  proxy  fights.  However,  such  provisions  could  have  the  effect  of  discouraging  others  from  making
tender offers for our shares and may have the effect of delaying changes in our control or management. As a consequence, these provisions may also inhibit
fluctuations in the market price of our stock that could result from actual or rumored takeover attempts. We believe that the benefits of these provisions,
including increased protection of our potential ability to negotiate with the proponent of an unfriendly or unsolicited proposal to acquire or restructure our
company,  outweigh  the  disadvantages  of  discouraging  takeover  proposals,  because  negotiation  of  takeover  proposals  could  result  in  an  improvement  of
their terms.
