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  multi-specific  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 candidate
based on the ADAPTIR-FLEX platform which is 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.

STRATEGY

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

Advancing  our  lead  clinical  stage  candidate,  APVO436,  through  clinical  development  to  evaluate  its  therapeutic  potential  alone  and  in
combination with other therapies. We are continuing enrollment and dosing in a Phase 1b dose expansion study.  This is a multi-center, multi-cohort trial
designed to evaluate APVO436 in adult patients with acute myeloid leukemia (AML) both in monotherapy and in combination with current standard-of
care therapies.  Enrollment is on-going at multiple centers across the United States.  The Company is actively recruiting new centers to participate in the
trial, and plans to be open in up to 20 clinical sites nationally.

Advancing  our  preclinical  stage  candidate,  ALG.APV-527,  developed  in  partnership  with  Alligator  Bioscience  AB  (Alligator),  into  clinical
stage. Aptevo and Alligator continue to advance preclinical candidate, ALG.APV-527 for the treatment of solid tumors, into the clinic and expect to file an
IND with the FDA in the US in the second half of 2022. A first-in-human study is expected to start in the second half of 2022. ALG.APV-527 targets 4-
1BB (T lymphocyte co-stimulatory receptor) and 5TA (tumor antigen) and is designed to reactivate antigen-primed T cells.

Advancing  our  ADAPTIR  and  ADAPTIR-FLEX  platforms,  focusing  on  immunotherapy  and  the  development  of  novel  bispecific  and  multi-
specific proteins for the treatment of cancer. We focus on product development using our ADAPTIR and ADAPTIR-FLEX platforms. We plan to generate
additional monospecific, bispecific, and multi-specific protein immunotherapies for development, potentially with other collaborative partners, to exploit
the potential of the ADAPTIR and ADAPTIR-FLEX platforms. We will select novel 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 multi-specific 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  and  cellular  biology,
immunology,  oncology,  pharmacology,  translational  services,  antibody  engineering  and  the  development  of  protein  therapeutics.  This  includes  target
validation,  preclinical  proof  of  concept,  cell  line  development,  protein  purification,  assay  and  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, preclinical testing, IND preparation, 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  multi-specific  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 multi-specific 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 technologies. 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,  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.

3

 
 
 
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.

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  multi-specifics  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 preclinical 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  multi-specifics  can  be  produced  using  standard  manufacturing  practices.
Further clinical and preclinical 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

Product Portfolio

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

Product Candidates

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

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

APVO436. a bispecific CD3xCD123 ADAPTIR that is designed to engage CD3 and CD123 to redirect T-cells to destroy leukemia cells expressing
the target CD123 molecule on their surface. This antibody-like recombinant protein therapeutic is designed to engage both leukemia cells and T-cells of the
immune system and activate T cells only when engaging CD3 to trigger the destruction of leukemia cells. Importantly, CD123 is not only expressed on the
leukemic  blast  cells  but  is  also  expressed  on  leukemic  stem  cells,  differentiating  it  from  other  tumor  antigens.  APVO436  has  been  engineered  using
Aptevo's proprietary platform technology and is uniquely designed to reduce the likelihood and severity of cytokine release syndrome (CRS). APVO436
has received orphan drug designation ("orphan status") for acute myeloid leukemia (AML) according to the Orphan Drug Act.

In Part 2 of APVO436-5001 which is the dose expansion of this Phase 1b multi-center study, 5 cohorts of AML patients are being simultaneously
enrolled  to  evaluate  up  to  90  adult  patients.  Cohorts  include  both  monotherapy  and  combination  therapy  protocols  including  current  standard  of  care
therapies.  The  Company  anticipates  using  the  outcomes  from  the  Phase  1b  trial  to  inform  the  APVO436  advanced  clinical  program.  A  patient  who
experienced complete remission was reported on November 23, 2021. On February 9, 2022, Aptevo announced that this patient will proceed to transplant.
Complete remission and transplant in patients who have failed prior frontline therapy such as this one, are indicators that the patient is making positive
clinical progress in fighting this difficult-to-treat disease. The expansion trial is designed to evaluate the safety and tolerability of APVO436 when it is used
as  an  adjunct  to  the  standard  of  care  and  as  monotherapy,  and to obtain  a  preliminary  assessment  of  the anti-leukemia activity  of  APVO436  in  both
modalities.

Cohort Therapy Description

Relapsed/refractory AML patients:  Combination therapy in relapsed patients and those with primary refractory AML that
failed  to  respond  to  frontline  standard  induction  chemotherapy.  Patients  will  be  treated  with  the  standard  chemotherapy
drug  cytarabine  or  the  standard  chemotherapy  triple  drug  combination  MEC  (mitoxantrone,  etoposide,  cytarabine)  plus
APVO436.

Poor  prognostic  but  fit  primary  or  secondary  AML  patients  who  are  treatment-naïve,  in  first  relapse  or  with  primary
refractory disease will receive APVO436 in combination with venetoclax and azacytidine.

APVO436  will  be  administered  as  monotherapy  to  AML  patients  in  CR  post  frontline  therapy  for  consolidation.  In
addition,  patients  in  first  relapse  (CR1<1  year)  and  patients  with  primary  refractory  disease  will  also  be  enrolled  and
receive treatment with APVO436.

AML patients in first remission with a MRD+ status following standard of care frontline therapy will receive APVO436 in
combination with oral azacytidine.

AML patients in second remission with MRD+ status will receive APVO436 as a dose intensive monotherapy regimen.

In  2021,  the  Company  completed  a  Phase  1b  open-label,  dose-escalation  clinical  trial  in  the  U.S.  evaluating  APVO436.  Patients  received
APVO436 by intravenous dosing for up to six 28-day cycles. The objective of the trial was to evaluate safety, pharmacokinetics, and pharmacodynamics of
APVO436 in AML and MDS patients. Forty-six patients with both AML and MDS were enrolled in the trial. A recent presentation at the American Society
of  Hematology  (ASH)  revealed  the  safety  profile  and  some  preliminary  efficacy  data  in  a  heavily  pretreated  population.  APVO436  was  generally  well
tolerated and two patients with unfavorable cytogenetics and/or adverse risk genomic mutations in the cohorts that received 12 mcg and 18 mcg flat dose
achieved a complete remission (CR) as their best overall response. Maximum tolerated dose (MTD) was not reached in this study and 18 mcg is now being
tested in a multi-center, multi-cohort expansion trial evaluating a total of 90 patients with AML.

The  most  common  APVO436-related  AEs  were  infusion-related  reactions  (IRR)  occurring  in  thirteen  (28.3%)  patients  and  cytokine  release
syndrome (CRS) occurring in ten (21.7%). No hematologic DLT was observed in any of the ten dose cohorts. Ten patients experienced twelve episodes of
Grade  3  febrile  neutropenia  and  each  one  of  these  twelve  episodes  was  reported  as  not  related  to  APVO436.  APVO436-related  transient  neurotoxicity
occurred in five of forty-six patients (10.9%). It was mild with Grade 1 AEs including headache, tremor, dizziness, lethargy, insomnia, memory loss, and
confusion. A single case of Grade 3 confusion was encountered on the first day of treatment and resolved within a day. APVO436-associated CRS was
generally manageable with standard of care and in most cases it resolved rapidly with the administration of tocilizumab at standard doses combined with
dexamethasone.  APVO436-related  CRS  was  not  required  for  clinically  meaningful  responses  in  R/R  AML  patients,  and  it  did  not  affect  their  survival
outcome.  Notably  patients  who  developed  CRS  after  APVO436  therapy  were  not  more  or  less  likely  to  have  a  favorable  response.  Among  eight  AML
patients with favorable responses, four experienced a CRS and four did not. APVO436-related CRS was not required for clinically meaningful responses in
R/R AML patients, and it did not affect the survival outcome. Prolonged stabilization of disease, partial remissions and complete remissions were achieved
in  both  patients  who  experienced  CRS  as  well  as  patients  who  did  not  experience  CRS  after  APVO436  infusions.  In  addition,  3  of  6  evaluable  MDS
patients developed a marrow CR.

A  potential  complication  associated  with  treatment  using  bispecific,  T-cell  engaging  antibodies  is  a  systemic  inflammatory  syndrome  known  as
Cytokine Release Syndrome. 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  to  be  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,
prostate, breast, cervical, colorectal, endometrial, and bladder cancers. Aptevo and Alligator plan to file an IND with the FDA in the US in 2022 and to
subsequently commence first in human study in the second half of 2022.

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 immunosuppressive 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.

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  the  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.

7

 
 
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), and JNJ-63709178 (Janssen). 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). Bispecific in the clinic
targeting 5T4 include GenMab and Abbvie’s (GEN1044), a 5T4 x CD3 DuoBody, in Phase 1/2 trials. 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 (AMG506) and Hoffmann-La Roche (RO7122290) for treatment of advanced
solid tumors. Another bispecific targets 4-1BB x HER (Cinrebafusp Alfa, PRS343) which is in  phase  2  clinical  development  by  Pieris  for  treatment  of
HER2+ solid tumors.

Furthermore, we face significant competition in the oncology market in general, including from: AbbVie Inc., ABL Bio, Aduro, Inc., Affirmed,
Amgen  Inc.,  AnaptysBio,  Inc.,  Astellas  Pharma  Inc.,  Bayer  AG,  Bicycle  Therapeutics,  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, I-Mab Biopharma, 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.,  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.

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.

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  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.

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 BioSolutions Inc (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 received the rights to the platform
patent family upon our spinoff from Emergent.

9

 
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 patent application under the Patent Cooperation Treaty (PCT) that we filed in 2021. The
PCT patent application allows 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.  

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.

Preclinical Therapeutic Candidates. We routinely file United States provisional patent applications and/or Patent Cooperation Treaty (PCT) patent
applications  on  our  preclinical  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

10

 
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  ongoing 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

Preclinical Testing. Before beginning testing of any compounds with potential therapeutic value in human subjects in the United States, stringent
government requirements for preclinical data must be satisfied. Preclinical 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 preclinical 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  preclinical  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.

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 combinations, or in different population to determine the recommended Phase 2 dose
and strategy.
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

11

 
 
 
 
 
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 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 FDA for 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.

12

 
 
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, preclinical 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.

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.

13

 
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.

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.

14

 
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  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.  Manufacturers  and  other  parties  involved  in  the  supply  chain  for  prescription  drug  products  must  also  comply  with  product  tracking  and  tracing
requirements  and  for  notifying  the  FDA  of  counterfeit,  diverted,  stolen  and  intentionally  adulterated  products  or  products  that  are  otherwise  unfit  for
distribution  in  the  United  States.  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.

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.

15

 
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.

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 Trial Regulation EU 536/2014 (“CTR”) repealed the Clinical Trials Directive 2001/20/EC, as amended (“CTD”) on January
31,  2022,  subject  to  a  three-year  transition  period.  The  CTR  makes  it  possible  within  the  EU  for  sponsors  to  submit  a  single  harmonized  electronic
submission  via  a  single  online  platform  known  as  the  Clinical  Trials  Information  System  (“CTIS”)  for  approval  to  conduct  a  clinical  trial  in  several
European  countries  and  have  a  single  assessment  process  for  clinical  trials  conducted  in  multiple  member  states.  Under  the  CTR,  sponsors  can  use  the
CTIS  from  January  31,  2022  but  are  not  obliged  to  use  it  immediately,  in  line  with  a  three-year  transition  period.    Sponsors  may  use  CTIS  to  apply  to
conduct a clinical trial under the CTR or may choose to apply to conduct a trial under the CTD until January 30, 2023.  From January 31, 2023, sponsors
will  need  to  use  CTIS  to  apply  to  start  a  new  clinical  trial  in  the  EU/EEA.    From  January  31,  2025,  any  trials  approved  under  the  CTD  that  continue
running will need to comply with the CTR and their sponsors must have recorded information on such trials in CTIS.

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

16

 
 
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 (defined to include doctors, dentists, optometrists, podiatrists and chiropractors) and teaching hospitals,
and ownership or investment interest held by physicians and their family members. Effective January 1, 2022, these reporting obligations extend to include
transfers  of  value  made  to  certain  non-physician  providers  (physician  assistants,  nurse  practitioners,  clinical  nurse  specialists,  certified  registered  nurse
anesthetists and anesthesiologist assistants, and certified-nurse midwives).

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.

Professionalism

17

 
 
 
 
We consider these values to be an integral part of our corporate goal setting and review process. We believe in empowering our employees and
consider them as owners of the business. We treat each other with respect and maintain a high level of professionalism and accountability. Our Board of
Directors and executive team continues to monitor and focus on our human capital resources to ensure we live by our core values.

Diversity, Equity, and Inclusion

Diversity,  equity,  and  inclusion  (DEI)  is  of  great  importance  to  our  culture,  day-to-day  operations,  and  future  success.  Aptevo  is  an  equal
opportunity employer, and we are committed to fostering DEI within our work environment and beyond. We believe DEI promotes our business growth,
drives  innovation  in  the  therapeutic  product  candidates  we  develop,  and  in  the  way  we  solve  problems.  Our  efforts  are  focused  on  hiring  and  retaining
qualified candidates, and promoting a supportive and inclusive working environment for all of our employees. The Company is resolute on its commitment
to the development and fair treatment of all candidates and employees, including equal opportunity hiring and advancement practices and policies, and anti-
harassment and anti-retaliation policies. We believe that fostering diversity, equity, and inclusion is a key element to discovering, developing, and bringing
transformative therapies to patients. As of December 31, 2021, 55% of our workforce and 44% of our leadership (at the Director level and above) were
female. In addition, 44% of our workforce and our leadership (at the Director level and above) were racially or ethnically diverse. We strive to build a
workforce representative of the people we serve and to nurture an inclusive culture where all voices are welcomed, heard, and respected.

Recruiting and Retention

We invest in resources to recruit, develop, and retain the talent needed to achieve our business goals. We believe in supporting our employees to
reach their full potential and strive to promote internally. We have been successful in attracting and retaining talented personnel to support our business,
though competition for personnel in our industry is intense.

Compensation and Benefits

Our compensation packages are designed to attract and retain talent, drive Company performance and achieve business goals. In setting appropriate
compensation levels, we look at the average base pay rate for each position based on market data. We also offer an annual cash incentive program and long-
term  equity  incentive  plans  designed  to  assist  in  attracting,  retaining,  and  motivating  employees  and  promoting  the  creation  of  long-term  value  for
stockholders. Further, all employees are eligible for health insurance and other health benefits, paid and unpaid leaves, retirement benefits with Company
match,  and  life  and  disability  coverage/insurance.  We  have  an  unlimited  paid  time  off  policy  that  provides  employees  with  considerable  flexibility  in
scheduling time away from work.

Health & Safety

Employee safety and well-being is of paramount importance to us and was of continued focus in 2021 in light of the COVID-19 global pandemic.
The  Company  adjusted  its  working  environment  and  operations  since  the  onset  of  the  COVID-19  global  pandemic  to  ensure  only  essential  employees,
which mainly include our research and development team, worked onsite, and transitioned all non-essential employees to remote work. We equipped our
employees working remotely with necessary equipment and tools to continue to collaborate and remain productive. To ensure health and safely of on-site
employees, we provided them with necessary personal protective equipment and implemented new safety procedures, including social distancing while in
the office, and wearing masks while on site.

Additionally,  we  have  an  Environmental,  Health  and  Safety  program  that  focuses  on  implementing  policies  and  training  programs,  as  well  as
performing self-audits to enhance work safety. Importantly, during the COVID-19 pandemic, our continuing focus on safe work practices has enabled us to
preserve business continuity without sacrificing our commitment to keeping our colleagues and workplace visitors safe.

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,

ORGANIZATIONAL HISTORY

18

 
 
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 cash flow 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.
The ongoing COVID-19 pandemic 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 commencement, enrollment of patients or completion of our clinical trials, the time to reach
critical trial data and receipt of any necessary regulatory approvals could be delayed.
The  results  of  our  current  and  planned  preclinical  studies  and  clinical  trials  may  not  satisfy  the  requirements  of  the  FDA  or  non-U.S.
regulatory authorities.  Results from early-preclinical studies and clinical trials may not be predictive of results from later-stage or other
trials and interim or top line data may be subject to change or qualification based on the complete analysis of data.
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.
We depend on third parties to conduct our clinical and non-clinical trials. If these third parties do not effectively carry out their contractual
duties, comply with regulatory requirements or meet expected

deadlines,  we  may  not  be  able  to  obtain  regulatory  approval  for  or  commercialize  our  product  candidates  and  our  business  could  be
substantially harmed.
Our  ability  to  grow  revenues  and  execute  on  our  long-term  strategy  depends  heavily  on  our  ability  to  discover,  develop,  and  obtain

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 years ended December 31, 2021 and
2020, we had net losses of $28.5 million and $17.8 million, respectively. As of December 31, 2021, we had an accumulated deficit of $214.1 million. We
expect to continue to incur annual net operating losses for the foreseeable future, and will require substantial resources over the next several years as we
expand our efforts to discover, develop and commercialize immunotherapeutic candidates. 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  with  MidCap  Financial
(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 February 2022 (the Purchase Agreement),
and exercises of warrants will provide us with sufficient liquidity to meet our cash requirements through at least next twelve months, 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, 2021, we had cash, cash equivalents, and restricted cash in the amount of $46.3 million. We will require additional funding to
grow  our  business  including  to  support  the  ongoing  clinical  development  of  APVO436,  develop  additional  products,  support  commercial  marketing
activities,  or  otherwise  provide  additional  financial  flexibility.  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  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;

20

 
 
 
 
 
 
 
 
 
 
 
 
 
 
•

•

•

•

•

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;

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

the cost of preparing, filing and prosecuting patent applications, obtaining, maintaining, enforcing and protecting our intellectual property
rights and defending intellectual property-related claims.

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 million worth of shares of our common stock to issue from our Purchase Agreement with
Lincoln Park Capital Fund, LLC, or Lincoln Park, entered into in February 2022, and (iii) the issuance of up to 350,589 remaining outstanding shares of
common stock as of December 31, 2021 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.

Our business is affected by macroeconomic conditions, including rising inflation, interest rates and supply chain constraints.  

Various macroeconomic factors could adversely affect our business and the results of our operations and financial condition, including changes in
inflation,  interest  rates  and  overall  economic  conditions  and  uncertainties  such  as  those  resulting  from  the  current  and  future  conditions  in  the  global
financial  markets.  For  instance,  inflation  could  negatively  impact  the  Company  by  increasing  our  labor  costs,  through  higher  wages  and  higher  interest
rates. Recent supply chain constraints have led to higher inflation, which if sustained could have a negative impact on the Company's product development
and operations. If inflation or other factors were to significantly increase our business costs, our ability to develop our current pipeline and new therapeutic
products may be negatively affected. Interest rates, the liquidity of the credit markets and the volatility of the capital markets could also affect the operation
of our business and our ability to raise capital in order to fund our operations. Similarly, these macroeconomic factors could affect the ability of our third-
party suppliers and manufacturers to manufacture all clinical trial materials for our product candidates.

Actions of activist stockholders against us have been and could be disruptive and costly and may cause uncertainty about the strategic direction of our
business.

Stockholders have in the past and may, from time to time, engage in proxy solicitations or advance stockholder proposals, or otherwise attempt to
effect changes and assert influence on our board of directors and management. For example, on February 9, 2021, Tang Capital Partners LP, Tang Capital
Management,  LLC  and  Kevin  Tang  (collectively,  “Tang”)  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. Activist campaigns that contest or conflict with our strategic direction or seek
changes in the composition of our board of directors or management could have an adverse effect on our operating results and financial condition. A proxy
contest  would  require  us  to  incur  significant  legal  and  advisory  fees,  proxy  solicitation  expenses  and  administrative  and  associated  costs  and  require
significant time and attention by our board of directors and management, diverting their attention from the

21

 
 
 
 
 
 
 
pursuit of our business strategy. Any perceived uncertainties as to our future direction and control, our ability to execute on our strategy, or changes to the
composition of our board of directors or senior management team arising from a proxy contest could lead to the perception of a change in the direction of
our business or instability which may result in the loss of potential business opportunities, make it more difficult to pursue our strategic initiatives, or limit
our  ability  to  attract  and  retain  qualified  personnel  and  business  partners,  any  of  which  could  adversely  affect  our  business  and  operating  results.  If
individuals are ultimately elected to our board of directors with a specific agenda, it may adversely affect our ability to effectively implement our business
strategy and create additional value for our stockholders. We may choose to initiate, or may become subject to, litigation as a result of the proxy contest or
matters arising from the proxy contest, which would serve as a further distraction to our board of directors and management and would require us to incur
significant additional costs. In addition, actions such as those described above could cause significant fluctuations in our stock price based upon temporary
or speculative market perceptions or other factors that do not necessarily reflect the underlying fundamentals and prospects of our business.

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 a 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 ongoing 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 affected, 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 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, as a result of a variety of factors,

including:

•
•
•

•

the level and timing of any milestone or deferred payments with respect to sales of IXINITY by Medexus;
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 the ongoing COVID-19 pandemic, 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. In 2021, we continue to see an impact of COVID-19 on our
business  as  some  of  our  clinical  sites  were  at  reduced  capacity.  These  and  other  factors  may  have  a  material  adverse  effect  on  our  business,  results  of
operations and financial condition.

22

 
 
 
 
 
Our future cash flow 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  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
additional  $32.5  million  based  on  the  achievement  of  sales  milestones  in  2022,  2023,  and  2024  (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.  The  Company
received a $10 million milestone payment in March 2022 and incurred $0.5 million in transaction costs. The proceeds from the milestone, net of transaction
costs, will be recorded as additional liability related to sale of future royalties on the balance sheet in the first quarter of 2022. The Company is eligible to
receive additional payments in aggregate of up to $22.5 million based on achievement of sales milestones in 2023 and 2024.

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;

23

 
 
 
 
 
•

•

•

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 General Counsel, SoYoung Kwon, our VP of Finance, Daphne Taylor, 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. Moreover, we have recently experienced increased levels of attrition. On August 25, 2021,
Jane Gross, resigned as the Chief Scientific Officer of the Company effective September 17, 2021 and transitioned into a consulting relationship with the
Company through December 31, 2021. Attracting, retaining or replacing these personnel on acceptable terms may be difficult and time-consuming given
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. Due to our equity plan proposal not receiving stockholder approval at the Company’s annual meeting in 2021, we may not have sufficient equity
available to attract and retain qualified personnel. In addition, we have experienced and may experience an impact on the health of key personnel due to the
ongoing COVID-19 pandemic.

The ongoing COVID-19 pandemic 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, 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;
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

24

 
 
 
 
 
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  or  Pfizer  to  successfully  commercialize  RUXIENCE;  and  negative
impacts on suppliers and licensees. The global outbreak of COVID-19 continues to rapidly evolve. The ongoing 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 ongoing 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  ongoing  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  guidance  several  times  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.

The extent to which the ongoing 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, the effectiveness of actions taken in the
United  States  and  other  countries  to  contain  and  treat  the  disease,  including  the  effectiveness  of  vaccination  programs,  and  whether  businesses  and  the
economy in general will continue to reopen and stay open.

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  of  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,

25

 
 
 
 
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, could result in an event of default. 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 completed a Section 382 study and experienced an “ownership change” as defined in Section 382 of the U.S. Internal Revenue Code of 1986, as
amended (the Code), 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, none of which permanently limits our federal tax attributes assuming sufficient income.  

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% stockholders” 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% stockholders 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
stockholder  becoming  a  5%  stockholder  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.

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,  2021,  we  had  approximately  $159.6  million  and  $70.3  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. Federal net operating loss carryforwards incurred in 2018 and in future years may
be carried forward indefinitely, but the usage of such federal net operating losses is limited. We completed an IRC Section 382 study on our federal tax
attributes and determined that the annual utilization of federal net operating loss carryforwards is limited. It is not expected that the annual limitations will
result in the expiration of tax attribute carryforwards prior to utilization assuming sufficient income.

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.

Our  investments  are  subject  to  market  and  credit  risks  that  could  diminish  their  value  and  these  risks  could  be  greater  during  periods  of  extreme
volatility  or  disruption  in  the  financial  and  credit  markets,  which  could  adversely  impact  our  business,  financial  condition,  results  of  operations,
liquidity and cash flows.

Our  investments  and  derivative  financial  instruments  are  subject  to  risks  of  credit  defaults  and  changes  in  market  values.  Periods  of
macroeconomic  weakness  or  recession,  heightened  volatility  or  disruption  in  the  financial  and  credit  markets  could  increase  these  risks,  potentially
resulting  in  other-than-temporary  impairment  of  assets  in  our  investment  portfolio.  The  impact  of  geopolitical  tension,  such  as  a  deterioration  in  the
bilateral relationship between the US and China or increasing escalation of conflict between Russia and Ukraine, including any additional sanctions, export
controls or other restrictive actions that may be imposed by the US and/or other countries against governmental or other entities in, for example, Russia,
also could lead to disruption, instability and volatility in the global markets, which may have an impact on our investments across negatively impacted
sectors or geographies.

Product Development Risks

The results of our current and planned preclinical studies and clinical trials may not satisfy the requirements of the FDA or non-U.S. regulatory
authorities.  Results from early-preclinical studies and clinical trials may not be predictive of results from later-stage or other trials and interim or top
line data may be subject to change or qualification based on the complete analysis of data.

We are very early in our clinical trial with APVO436 and clinical failure can occur at any stage of preclinical or clinical development. Preclinical
studies and 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  preclinical  studies  and  clinical  trials  does  not  mean  that  future  larger  registration  clinical  trials  will  be
successful  and  interim  results  of  a  clinical  trial  do  not  necessarily  predict  final  results.  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.  In  some  instances,  there  can  be  significant  variability  in  safety  or  efficacy  results  between  different  clinical  trials  of  the  same  product
candidate due to numerous factors, including changes in trial procedures set forth in protocols, differences in the size and type of the patient populations,
changes in adherence to the dosing regimen and other clinical trial protocols and the rate of dropout among clinical trial participants. In addition, preclinical
and clinical data are often susceptible to various interpretations and analyses, and many companies whose product candidates performed satisfactorily in
preclinical studies and clinical trials have nonetheless failed to obtain marketing approval. Product candidates in later stages of clinical trials may fail to
show the desired safety and efficacy profile despite having progressed through preclinical studies and initial clinical trials. A number of companies in the
pharmaceutical  and  biopharmaceutical  industry  have  suffered  significant  setbacks  in  advanced  clinical  trials  due  to  lack  of  efficacy  or  adverse  safety
profiles, notwithstanding promising results in earlier studies, and we cannot be certain that we will not face similar setbacks. Even if early-stage clinical
trials  are  promising,  we  may  need  to  conduct  additional  clinical  trials  of  our  product  candidates  in  additional  patient  populations  or  under  different
treatment  conditions  before  we  are  able  to  seek  approvals  from  the  FDA  and  regulatory  authorities  outside  the  United  States  to  market  and  sell  these
product candidates. Any of these events could limit the commercial potential of our product candidates and have a material adverse effect on our business,
prospects, financial condition and results of operations. 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.

27

 
 
In  addition,  our  APVO436  clinical  trial  are  open-label  studies  and  conducted  at  a  limited  number  of  clinical  sites  on  a  limited  number  of
patients.   An  “open-label”  clinical  trial  is  one  where  both  the  patient  and  investigator  know  whether  the  patient  is  receiving  the  investigational  product
candidate  or  either  an  existing  approved  drug  or  placebo.    Most  typically,  open-label  clinical  trials  test  only  the  investigational  product  candidate  and
sometimes  may  do  so  at  different  dose  levels.  Open-label  clinical  trials  are  subject  to  various  limitations  that  may  exaggerate  any  therapeutic  effect  as
patients in open-label clinical trials are aware when they are receiving treatment. Open-label clinical trials may be subject to a “patient bias” where patients
perceive their symptoms to have improved merely due to their awareness of receiving an experimental treatment. In addition, open-label clinical trials may
be subject to an “investigator bias” where those assessing and reviewing the physiological outcomes of the clinical trials are aware of which patients have
received treatment and may interpret the information of the treated group more favorably given this knowledge. The results from these clinical trials may
not be predictive of future clinical trial results with APVO436 or other product candidates.

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. 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. Further, others, including regulatory agencies, may not accept or
agree  with  our  assumptions,  estimates,  calculations,  conclusions  or  analyses  or  may  interpret  or  weigh  the  importance  of  data  differently,  which  could
impact  the  value  of  the  particular  program,  the  approvability  or  commercialization  of  the  particular  product  candidate  or  product  and  our  company  in
general.  In  addition,  the  information  we  choose  to  publicly  disclose  regarding  a  particular  study  or  clinical  trial  is  based  on  what  is  typically  extensive
information, and you or others may not agree with what we determine is material or otherwise appropriate information to include in our disclosure.

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;

28

 
 
 
 
 
 
 
 
 
•

•

•

•

•

•

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 non-clinical 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  non-clinical  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.

We may not be able to file investigational new drug applications, or INDs, or IND amendments to commence additional clinical trials on the timelines
we expect, and even if we are able to, the FDA may not permit us to proceed.

We expect to submit an IND for ALG.APV-527 to the FDA in 2022, however, we may not be able to file future INDs for our product candidates on
the timelines we expect. For example, we may experience manufacturing delays or other delays with IND-enabling studies. Moreover, we cannot be sure
that submission of an IND will result in the FDA allowing further clinical trials to begin, or that, once begun, issues will not arise that suspend or terminate
clinical trials. Additionally, even if such regulatory authorities agree with the design and implementation of the clinical trials set forth in an IND, we cannot
guarantee that such regulatory authorities will not change their requirements in the future. These considerations also apply to new clinical trials we may
submit as amendments to existing INDs or to a new IND. Any failure to file INDs on the timelines we expect or to obtain regulatory approvals for our trials
may prevent us from completing our clinical trials or commercializing our products on a timely basis, if at all.

If we experience delays or difficulties in the commencement, enrollment of patients or completion of our 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,  enroll  and  maintain  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. Furthermore, APVO436 has received
orphan drug designation for AML and thus has a relatively small patient population. Also, the eligibility criteria of our clinical trials may further limit the
pool of available study

29

 
 
 
 
 
 
 
 
 
participants as we require that patients have specific characteristics that we can measure to assure their disease is either severe enough or not too advanced
to include them in a study. In addition, the global outbreak of the COVID-19 pandemic makes it more difficult to initiate studies and enroll patients and the
process of finding and diagnosing eligible patients under these conditions may prove costly.

Patient enrollment is affected by other factors including:

•

•

•

•

•

•

•

•

•

•

•

the severity of the disease under investigation;

the design of the clinical trial, including 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;

our ability to recruit clinical trial investigators with the appropriate competencies and experiences;

our ability to obtain and maintain patient consents;

the ability to monitor patients adequately during and after treatment;

reporting of preliminary results of any of our clinical trial sites;

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

factors we may not be able to control that may limit patients, principal investigators or staff or clinical site availability, such as the ongoing
COVID-19 pandemic.

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, delays in the
availability of preliminary or final results, and 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, either when used
alone or in combination with other approved or investigational therapies, could cause us or regulatory authorities to interrupt, delay or halt our development
activities  and  manufacturing  and  distribution  operations  and  could  result  in  a  more  restrictive  label,  the  imposition  of  a  clinical  hold,  suspension,
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  conduct  clinical  trials  of  our  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, the FDA or comparable foreign regulatory authorities could suspend or terminate a
clinical trial or deny approval of our product candidates. Furthermore, we may to evaluate our product candidates in combination with approved and/or
experimental therapies. These combinations may have additional or

30

 
 
 
 
 
 
 
 
 
 
 
 
more  severe  side  effects  than  caused  by  our  product  candidate  as  monotherapies.  The  uncertainty  resulting  from  the  use  of  our  product  candidate  in
combination  with  other  therapies  may  make  it  difficult  to  accurately  predict  side  effects  or  efficacy  in  potential  future  clinical  trials.  If  our  product
candidates receive marketing approval and we or others later identify undesirable side effects caused by such products, a number of potentially significant
negative consequences may result, including:

•

•

•

•

•

•

•

regulatory authorities may require us to conduct additional clinical trials or abandon our research efforts for our other product candidates;

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;

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 approval and 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. If these third parties do not effectively  carry out their contractual duties,
comply with regulatory requirements or meet expected deadlines, we may not be able to obtain regulatory approval for or commercialize our product
candidates and our business could be substantially harmed.

We  do  not  have  the  ability  to  independently  conduct  the  clinical  and  preclinical  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 preclinical trials of our product candidates, and we expect to continue to do so. For example, Dr. Dirk Huebner is
providing clinical trial and medical affairs oversight duties as an independent consultant. We rely heavily on Dr. Huebner and these other third parties for
successful execution of our clinical and preclinical 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, and non-clinical 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 non-clinical 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.

31

 
 
 
 
 
 
 
 
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  ongoing  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  preclinical  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.

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 non-clinical 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.

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
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.

32

 
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. In some cases, the
technical skills required to manufacture our products or product candidates may be unique or proprietary to the original manufacturer and we may have
difficulty,  or  there  may  be  contractual  restrictions  prohibiting  us  from,  transferring  such  skills  to  an  alternate  supplier  in  a  timely  fashion  if  at  all.  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  the  ongoing  COVID-19  pandemic,  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

33

 
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,  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  to  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  the  ongoing  COVID-19
pandemic,  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.

34

 
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 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.

We  have  in  the  past  and  may  in  the  future  conduct  clinical  trials  for  our  product  candidates  outside  the  United  States,  and  the  FDA  or  non-U.S.
regulatory authorities may not accept data from such trials in the development or approval of our product candidates in those jurisdictions.

We have in the past and may in the future conduct clinical trials outside the U.S. and the FDA and foreign regulatory authorities may not accept
those data in support of the further development or approval of our product candidates. The acceptance of trial data from clinical trials conducted outside
the United States by the FDA or applicable foreign regulatory authority may be subject to certain conditions. In cases where data from foreign clinical trials
are intended to serve as the basis for marketing approval in the United States, the FDA will generally not approve the application on the basis of foreign
data alone unless (i) the data are applicable to the United States population and United States medical practice; and (ii) the trials were performed by clinical
investigators of recognized competence and pursuant to GCP regulations. Additionally, the FDA’s clinical trial requirements, including sufficient size of
patient populations and statistical powering, must be met. Many foreign regulatory bodies have similar approval requirements.

In addition, such foreign trials will be subject to the applicable local laws of the foreign jurisdictions where the trials are conducted. There can be
no assurance that the FDA or any applicable foreign regulatory authority will accept data from trials conducted outside of the United States. If the FDA or
any applicable foreign regulatory authority does not accept such data, it would result in the need to conduct additional trials beyond those we have

35

 
planned, which would be costly and time-consuming and delay aspects of our business plan, and which may result in our product candidates not receiving
marketing approval for commercialization in the applicable jurisdiction.

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  preclinical  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 our 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
multi-specific  molecules  in  oncology  and  other  therapeutic  areas.  Our  goal  is  to  leverage  this  technology  to  make  targeted  investment  in  monospecific,
bispecific, and multi-specific 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  based  on  our  ADAPTIR  and  ADAPTIR-FLEX  platform  technologies,  our  ability  to  obtain
product revenues in

36

 
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  and  will  continue  to  face  substantial  competition  and  our  failure  to  effectively  compete  may  prevent  us  from  achieving  significant  market
penetration for our product candidates, if approved.

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., Affimed, Amgen Inc., AnaptysBio, Inc., Astellas
Pharma Inc., Bayer AG, Biogen Idec Inc., Boehringer Ingelheim GmbH, Chinook Therapeutics, 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., 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 ACA-mandated fees, and increasing the
point-of-sale discount that is owed by pharmaceutical manufacturers who

37

 
participate in Medicare Part D. On June 17, 2021, the U.S. Supreme Court dismissed the most recent judicial challenge to the ACA brought by several
states without specifically ruling on the constitutionality of the ACA. It is unclear how other healthcare reform measures of the Biden administration or
other  efforts,  if  any,  to  challenge,  repeal  or  replace  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, included aggregate reductions of Medicare payments to providers
of 2% 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,  with  the  exception  of  a  temporary  suspension  from  May  1,  2020  through  March  31,  2022  due  to  the
COVID-19 pandemic. Following the temporary suspension, a 1% payment reduction will occur beginning April 1, 2022 through June 30,
2022, and the 2% payment reduction will resume on July 1, 2022.

On May 30, 2018, the Right to Try Act, was signed into law. The law, among other things, provides a federal framework for certain patients
to access certain investigational new drug products that have completed a Phase 1 clinical trial and that are undergoing investigation for
FDA approval. Under certain circumstances, eligible patients can seek treatment without enrolling in clinical trials and without obtaining
FDA  permission  under  the  FDA  expanded  access  program.  There  is  no  obligation  for  a  pharmaceutical  manufacturer  to  make  its  drug
products available to eligible patients as a result of the Right to Try Act.

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 20, 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.

38

 
 
 
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.

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 non-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
expensive. All of the product candidates that we are developing, or may develop in the future, require research and development, non-clinical studies, non-
clinical 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  non-clinical  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

39

 
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.

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 non-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 products. 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

40

 
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 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

41

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
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

42

 
 
 
 
 
•

•

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. Effective January 1, 2022, applicable manufacturers are 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,

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

43

 
 
 
 
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, 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;

44

 
 
 
 
•

•

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 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

45

 
 
 
 
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 could have a
material and adverse effect on our business, financial condition and operating results.  

If approved, our products regulated as biologics may face competition from biosimilars approved through an abbreviated regulatory pathway.

The  Patient  Protection  and  Affordable  Care  Act,  as  amended  by  the  Health  Care  and  Education  Reconciliation  Act  of  2010,  or  collectively  the
ACA, includes a subtitle called the Biologics Price Competition and Innovation Act of 2009, or BPCIA, which created an abbreviated approval pathway for
biological products that are biosimilar to or interchangeable with an FDA-licensed reference biological product. Under the BPCIA, an application for a
biosimilar  product  may  not  be  submitted  to  the  FDA  until  four  years  following  the  date  that  the  reference  product  was  first  licensed  by  the  FDA.  In
addition, the approval of a biosimilar product may not be made effective by the FDA until 12 years from the date on which the reference product was first
licensed. During this 12-year period of exclusivity, another company may still market a competing version of the reference product if the FDA approves a
BLA for the competing product containing the sponsor’s own preclinical data and data from adequate and well-controlled clinical trials to demonstrate the
safety, purity, and potency of the other company’s product. The law is complex and is still being interpreted and implemented by the FDA. As a result, its
ultimate impact, implementation, and meaning are subject to uncertainty. We believe that any of our product candidates approved as a biological product
under a BLA should qualify for the 12-year period of exclusivity. However, there is a risk that this exclusivity could be shortened due to congressional
action or otherwise, or that the FDA will not consider our investigational medicines to be reference products for competing products, potentially creating
the opportunity for generic competition sooner than anticipated. Other aspects of the BPCIA, some of which may impact the BPCIA exclusivity provisions,
have also been the subject of recent litigation. Moreover, the extent to which a biosimilar, once licensed, will be substituted for any one of our reference
products in a way that is similar to traditional generic substitution for non-biological products is not yet clear, and will depend on a number of marketplace
and  regulatory  factors  that  are  still  developing.  If  competitors  are  able  to  obtain  marketing  approval  for  biosimilars  referencing  any  of  our  products,  if
approved,  our  products  may  become  subject  to  competition  from  such  biosimilars,  which  would  impair  our  ability  to  successfully  commercialize  and
generate revenues from sales of such products.

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.

46

 
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.

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

47

 
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.

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  the  ongoing  COVID-19  pandemic,  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 $3.11 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 the war in Ukraine. 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;

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 preclinical 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;

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 FDA’s 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  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. In the past, we were an emerging
growth  company  and  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 will no longer avail ourselves of this exemption since we
ceased  to  be  an  emerging  growth  company  since  August  2021.  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 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  Purchase  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

51

 
 
 
 
 
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.

Moreover, we currently have a short-term stockholder rights agreement in effect. This rights agreement was amended on November 4, 2021 to extend
the expiration date of such agreement from November 8, 2021 to November 5, 2022. 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

52

 
 
 
 
 
 
 
 
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 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.

53

 
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 ongoing COVID-19 pandemic also poses an increased security risk, due to the remote working environment.

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, 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.

If a breach of our information technology systems occurs, we may incur additional costs related to repairing or rebuilding our internal systems,
complying with breach notification laws, defending legal claims or proceedings, responding to regulatory actions, incurring penalties, and paying damages.
Moreover, it may be determined that as a result of such a breach there was a material weakness or significant deficiency in our internal controls or other
failure  of  our  control  environment.    If  such  a  breach  occurs,  it  may  have  a  material  adverse  effect  on  our  business,  results  of  operations,  and  financial
condition, and it may also negatively impact our reputation.

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.

54

 
Item 1B. Unresolved Staff Comments.

None.

Item 2. Properties.

We lease our headquarters office and laboratory space in Seattle, Washington. The Seattle facility is approximately 48,000 square feet and the lease

for the Seattle facility expires in April 2030.

Item 3. Legal Proceedings.

We  may  from  time  to  time  be  named  as  a  party  to  legal  claims,  actions  and  complaints,  including  matters  involving  employment  claims,  our

Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations.

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  multi-specific  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 of 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 candidate
based on the ADAPTIR-FLEX platform which is 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.

Recent Developments

Announced results from the Phase 1b dose escalation trial evaluating lead drug candidate, APVO436, for the treatment of AML and MDS.  Results

showed:

•

•

APVO436 exhibited a favorable safety profile with acceptable tolerability and generally manageable drug-related adverse events.

Promising clinical activity was observed in 11 of 40 patients (27.5%) evaluable for efficacy.  This included two complete remissions in
patients with AML and three complete marrow responses in patients with MDS.

Initiated the dose expansion part of the APVO436 Phase 1b trial, evaluating adult patients with acute myeloid leukemia (AML) in a multi-center,

multi-cohort study of up to 90 patients who will receive APVO436 in combination and monotherapy.

Published  three  articles  in  two  peer-reviewed  publications,  Cancers  and  Frontiers  in  Medicine,  discussing  APVO436  data.    Results  were  also

presented at the American Society of Hematology annual meeting in November 2021.

57

 
 
 
 
 
 
Announced  that  a  high-risk  AML  patient  treated  with  a  combination  of  chemotherapy  plus  APVO436  achieved  a  complete  remission  after  one
cycle  of  therapy.    The  chemotherapy  regimen  included  the  standard  leukemia  drugs  Mitoxantrone,  Etoposide,  and  Cytarabine.  The  patient  tolerated
treatment without evidence of overt toxicity. More recently, Aptevo reported that this patient will proceed to transplant.

Solidified  plans  with  Alligator  Bioscience  to  submit  an  IND  for  ALG.APV-527  in  the  second  half  of  2022  to  evaluate  the  compound  for  the

treatment of multiple solid tumor types.

•

Aptevo will investigate the initial differentiating benefits of ALG.APV-527 to induce stronger and more tumor-directed T cell activity with
the potential for improved safety and efficacy than existing 4-1BB monoclonal antibody treatments.

Received $35 million on March 30, 2021 from its sale of the right to royalty payments made by Pfizer with respect to net sales of RUXIENCE to

an entity managed by HCR.

Earned  a  $10  million  milestone  payment  related  to  2021  sales  of  RUXIENCE  under  the  terms  of  its  royalty  purchase  agreement  with  HCR.
Received the proceeds from the milestone payment in March 2022, which will be used to pay down our MidCap Financial term loan to $5 million, further
strengthening the Company’s balance sheet.

On November 22, 2021 and November 26, 2021, Tang filed statements on Schedule 13D/A to report that Tang had sold 1,760,000 shares of our
common stock. The shares sold represented Tang’s entire ownership position in the Company at that time and as of the date hereof we believe that Tang no
longer holds any of our shares of issued and outstanding common stock.

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 LLC (Aptevo BioTherapeutics), which was sold in February 2020 to Medexus and 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, 2021 Compared to Year Ended December 31, 2020

For the years ended December 31, 2021 and 2020, we had net losses of $28.5 million and $17.8 million, respectively. As of December 31, 2021,

we had an accumulated deficit of $214.1 million.

Royalty Revenue

For  the  years  ended  December  31,  2021  and  2020,  we  recorded  royalty  revenue  of  $12.3  million  and  $4.3  million,  respectively.  The  royalty
revenue relates to a Collaboration and License Agreement (Definitive 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-owned subsidiary of
Pfizer. The royalty term runs through January 2027, which is the seventh anniversary of the first commercial sale of the CD20 biosimilar. On March 30,
2021, we entered into the Royalty Purchase Agreement pursuant to which we sold to HCR the right to receive royalty payments made by Pfizer in respect
of net sales of RUXIENCE. We maintain our rights under the Definitive Agreement originally between Trubion and Wyeth, with the exception of the cash
flows  of  the  RUXIENCE  royalty  payments  purchased  by  HCR.  Due  to  our  continuing  involvement  under  the  Definitive  Agreement  originally  between
Trubion and Wyeth, we continue to recognize royalty revenue on net sales of RUXIENCE and record the royalty payments to HCR as a reduction of the
liability  when  paid.  As  such  payments  are  made  to  HCR,  the  balance  of  the  liability  will  be  effectively  repaid  over  the  life  of  the  Royalty  Purchase
Agreement. To the extent total future royalties collected are an amount less than the liability, the Company is not obligated to fund any such shortfall.

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 non-clinical studies and clinical trials, fees to professional service providers for analytical testing, consulting
costs,  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.

We expect our research and development spending will 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
the ongoing COVID-19 pandemic. While programs are still in the preclinical 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 research and development expenses by program for the years ended December 31, 2021 and 2020 are shown in the following table:

Research and development expenses increased by $1.1 million, to $19.0 million for the year ended December 31, 2021 from $17.9 million for the
year ended December 31, 2020. The increase is due to higher spending on consulting services for our APVO436 clinical trial as we continue to advance
that trial and increased spending on analytical analysis for our preclinical programs, including ALG.APV-527, APVO603, and APVO442. Further, we have
now started dosing in our Phase 1b Expansion program for our APVO436 clinical trial.

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, 2021, general and administrative expenses increased by $0.7 million, or 5%, to $14.7 million from $14.0 million
for the year ended December 31, 2020. This increase was primarily due to higher costs related to responding to stockholder activism matters and higher
employee costs.

Other Expense, Net

Other expense consists primarily of costs related to debt extinguishment, accrued exit fees on debt, non-cash interest on financing agreements, and
interest on debt. Other expense, net was $8.0 million for the year ended December 31, 2021 and $3.4 million for the year ended December 31, 2020. This
increase is primarily due to interest expense and accrued exit fees for the MidCap Credit Agreement, as well as non-cash interest expense for the Royalty
Purchase Agreement.

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 we received a payment in 2021 related to collection of certain accounts receivable,
and the sale of Aptevo BioTherapeutics in 2020.

The following table represents the components attributable to income from discontinued operations in the consolidated statements of operations (in

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. 

Sources of Liquidity

Royalty Purchase Agreement and Milestone Payments

On March 30, 2021, we entered into Royalty Purchase Agreement with HCR pursuant to which we sold HCR the right to receive royalty payments
made by Pfizer in respect to net sale of RUXIENCE. Under the Royalty Purchase Agreement, we received $35 million at closing and incurred $1.1 million
in  transaction  costs.  We  are  eligible  to  receive  additional  payments  in  aggregate  of  up  to  an  additional  $32.5  million  based  on  achievement  of  sales
milestones in 2022, 2023, and 2024. 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. The Company received $10 million milestone payment in March 2022 and incurred $0.5 million in transaction costs. The
Company is eligible to receive additional payments in aggregate of up to $22.5 million based on achievement of sales milestone in 2023 and 2024.

IXINITY Royalty Payments

On  February  28,  2020,  Aptevo  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  consideration  for  the  sale,
Aptevo received $30 million in cash at closing. In addition to the payment received at closing, the Company receives deferred payments based on quarterly
net sales of IXINITY and may also earn milestones from Medexus in the future. For the year ended December 31, 2021, Aptevo received $0.5 million from
Medexus related to IXINITY sales.

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, if any, will be effected pursuant to a Registration Statement on Form
S-3 which we filed on December 14, 2020. We did not issue any shares under the Equity Distribution Agreement for the year ended December 31, 2021.

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

61

 
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 a Purchase Agreement, and a Registration Rights Agreement with Lincoln Park Financial LLC (Lincoln
Park). Pursuant to the Purchase Agreement, Lincoln Park 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.  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. For the year
ended  December  31,  2021,  the  Company  issued  407,047  shares  of  common  stock  to  Lincoln  Park  under  the  Purchase  Agreement.  We  received  $10.2
million in proceeds from issuance of these shares over three-year period. Our 2018 Purchase Agreement and Registration Rights Agreement with Lincoln
Park expired in March 2022.

On February 16, 2022, the Company entered into a new Purchase Agreement and a Registration Rights Agreement with Lincoln Park. Under the
new Purchase Agreement, Lincoln Park committed to purchase up to $35.0 million worth of our common stock over a 36-month period commencing after
the  satisfaction  of  certain  conditions  set  forth  in  the  Purchase  Agreement.  The  purchase  price  per  share  will  be  based  off  of  prevailing  market  price;
provided, however, that the prevailing market price is not below $1.00. The Company agreed to issue 99,276 shares of our common stock to Lincoln Park
for no cash consideration as an initial fee for its commitment to purchase shares of our common stock under the Purchase Agreement.

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, 2021, 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 54,105 shares of the Company’s common stock and aggregate proceeds to the Company of approximately $1.0 million. As of
December 31, 2021, there were warrants to purchase 350,589 shares of common stock outstanding.

Liquidity

We have financed our operations to date primarily through revenue generated from our commercial products, the Royalty Purchase Agreement with

HCR, royalty payments from Pfizer, deferred payments from Medexus, the

62

 
 
 
 
 
 
sale of our hyperimmune products business in September 2017, the sale of Aptevo BioTherapeutics on February 28, 2020, public offerings of our common
stock, proceeds  from  issuance  of  our  common  stock  pursuant  to  our  2018  Purchase  Agreement  with  Lincoln  Park, 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 $28.5 million
and $17.8 million  for  the  years  ended  December  31,  2021  and  December  31,  2020,  respectively.  We  had  cash  and  cash  equivalents  of  $45.0  million,
restricted cash of $1.3 million, and an accumulated deficit of $214.1 million as of December 31, 2021.

For the year ended December 31, 2021, net cash used in our operating activities was $21.7 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.

Due to the ongoing COVID-19 pandemic, 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. Additionally,
we may experience potential impacts on our future milestones from HCR, which are based on global net sales of RUXIENCE, due to the effects of the
COVID-19 pandemic, which may impact Pfizer’s ability to continue to successfully commercialize the RUXIENCE business. We believe that our existing
cash resources, the Investment Amount and Milestone Amounts related to the Royalty Purchase Agreement with HCR, Purchase Agreement with Lincoln
Park, the cash to be generated from future IXINITY deferred payments, release of restricted cash securing letters of credit, and funds available to us from
the remaining principal balance of 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.

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;

our ability to obtain regulatory clearance to commence clinical trials for product candidates;

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;

63

 
 
 
 
 
 
 
 
 
 
•

•

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.

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 the ongoing COVID-19 pandemic, we may experience delays in clinical trials and
non-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. Once we begin participation in the Beat AML Master Clinical Trial, our purchase obligation for the Beat
AML  Master  Clinical  Trial  may  total  up  to  $8.1  million  over  four  years.  As  of  December  31,  2021,  we  have  not  begun  participation  in  the  Beat  AML
Master  Clinical  Trial  and  we  do  not  currently  intend  to  participate  under  the  current  trial  design.  The  Clinical  Trial  Participation  Agreement  contains  a
termination for convenience clause where we may terminate the agreement with 180 days prior written notice. We may re-assess our participation in the
master clinical trial as Part 2 (expansion phase) of our Phase 1b APVO436 clinical trial progresses.

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. 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. Additionally, the Company will use the $10 million milestone payment received on March 8, 2022, pursuant to our Royalty Purchase Agreement
with  HCR  to  pay  down  the  outstanding  principal  down  to  $5  million.  The  Company’s  Credit  Agreement  currently  references  LIBOR.  The  United
Kingdom’s Financial Conduct Authority (FCA), which regulates LIBOR, phased out one-week and two-month US Dollar LIBOR settings on December 31,
2021. All other US Dollar LIBOR settings, including the overnight, one-month, three-month, six-month and twelve-month, will be phased out on June 30,
2023. It is unclear if at that time LIBOR will cease to exist or if new methods of calculating LIBOR will be established such that it continues to exist after
2023. Our Credit Agreement with MidCap Financial currently references one-month LIBOR and also provides that we may amend the Credit Agreement to
reflect an alternative rate of interest upon the phase out of LIBOR.

64

 
 
 
 
 
 
On March 30, 2021, we entered into the Royalty Purchase Agreement pursuant to which the Company sold to HCR the right to receive royalty
payments  made  by  Pfizer  in  respect  of  net  sales  of  RUXIENCE.  Pursuant  to  the  Purchase  Agreement,  we  received  $35  million  at  closing  and  we  are
eligible to receive additional payments in aggregate of up to an additional $32.5 million based on the achievement of sales milestones in 2022, 2023, and
2024. The Company received $10 million milestone payment in March 2022 and incurred $0.5 million in transaction costs. The Company is eligible to
receive additional payments in aggregate of up to $22.5 million based on achievement of sales milestone in 2023 and 2024. We accounted for the Royalty
Purchase Agreement with HCR, including future milestone payments to be received, as a debt-like instrument within the scope of ASC 470-10-25, Debt –
Sales of Future Revenues or Various Other Measures of Income.

Our  principal  commitments  include  obligations  under  vendor  contracts  to  purchase  research  services  and  other  purchase  commitments  with  our
vendors. In the normal course of business, we enter into services agreements with contract research organizations, contract manufacturing organizations
and other third parties. Generally, these agreements provide for termination upon notice, with specified amounts due upon termination based on the timing
of termination and the terms of the agreement. The actual amounts and timing of payments under these agreements are uncertain and contingent upon the
initiation and completion of the services to be provided.

Critical Accounting Policies, and Significant Judgments, and Estimates

The preparation of our consolidated financial statements in conformity with accounting principles generally accepted in the United States (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.

Non-Cash Interest Expense and Liability Related to Sale of Future Royalties

The  Company  accounted  for  the  Royalty  Purchase  Agreement  with  HCR,  including  future  milestone  payments  to  be  received,  as  a  debt-like
instrument within the scope of ASC 470-10-25, Debt – Sales of Future Revenues or Various Other Measures of Income. We recorded the proceeds from the
Royalty  Purchase  Agreement  as  a  liability  related  to  the  sale  of  future  royalties,  net  of  transaction  costs,  and  amortized  the  balance  using  the  effective
interest method. To determine the amortization of the liability, the Company estimates the total amount of future net royalty payments over the life of the
arrangement.  The  total  amount  of  net  royalty  payments  over  the  life  of  the  arrangement,  less  the  net  proceeds  received,  will  be  recorded  as  non-cash
interest expense over the life of the arrangement using the effective interest method. Over the life of the arrangement, the actual effective interest rate will
be affected by the amount and timing of the net royalty payments received by HCR and changes in the Company’s royalty forecasts. The Company engages
third party consultant services in estimating total future net royalty payments and continually assesses the effective interest rate by comparing projected net
royalty payments to actual and adjusts the effective interest rate retrospectively. Future milestone payments will be recorded as additions to the liability
related to the sale of future royalties, net of transaction costs. While we believe our estimates are reasonable, actual net royalty payments may be different
than our projections. Historically, differences between estimated and actual net royalty payments have not been material.

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.

65

 
A substantial portion of our preclinical 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 preclinical 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.

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  sheets  of  Aptevo  Therapeutics  Inc.  (the  “Company”)  as  of  December  31,  2021  and  2020,  the
related consolidated statements of operations, cash flows, and changes in stockholders’ equity for the years 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, 2021 and 2020, and the consolidated results of its operations and its cash flows for the
years 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 audits. We are a public accounting firm registered with the Public Company Accounting Oversight Board
(United States) (“PCAOB”) and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the
applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audit in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audits to obtain reasonable
assurance  about  whether  the  consolidated  financial  statements  are  free  of  material  misstatement,  whether  due  to  error  or  fraud.  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 audits 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 audits 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 audits also included evaluating the accounting principles used and significant estimates made by
management, as well as evaluating the overall presentation of the consolidated financial statements. We believe that our audits provide a reasonable basis
for our opinion.

Critical Audit Matter

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

Non-Cash Interest Expense and Liability Related to Sale of Future Royalties

As described in Note 8, on March 30, 2021, the Company entered into a royalty purchase agreement (the Royalty Purchase Agreement) with an entity
managed by HealthCare Royalty Management, LLC (HCR), through which the Company sold the right to receive royalty payments made by Pfizer Inc.
related to the global net sales of RUXIENCE. The Company received $35 million at the closing of the agreement and is eligible to receive additional
payments in aggregate of up to an additional $32.5 million based on the achievement of RUXIENCE sales milestones in 2022, 2023, and 2024
(collectively, the Milestone Amounts). The Royalty Purchase Agreement further provides that, once HCR reaches aggregate royalty payments totaling
190% of the amount paid at closing plus

68

 
 
 
 
 
 
 
 
 
 
 
 
 
Milestone Amounts to the extent paid by HCR to the Company, Aptevo will be entitled to receive 50% of royalty interest payments thereafter. The
proceeds received from HCR were recorded as a debt financing, net of transaction costs, which are amortized over the estimated life of the arrangement
using the effective interest method. In order to determine the amortization of the liability, the Company is required to estimate the total amount of future
royalty payments to be received by HCR over the life of the arrangement. The total amount of future royalty payments received by HCR under the Royalty
Purchase Agreement, less the net proceeds paid to the Company, is recorded as non-cash interest expense over the life of the arrangement using the
effective interest method.

We identified the estimation of the non-cash interest expense and the liability related to the Royalty Purchase Agreement as a critical audit matter. There
was significant judgment by management when developing the estimate of the timing and amount of future royalties to be paid and the implied effective
interest rate in the arrangement. This in turn led to a high degree of auditor judgment, subjectivity, and effort in performing procedures and in evaluating
audit evidence relating to management’s estimate of the expected future royalties to be paid and the implied effective interest rate, including significant
assumptions of future royalty sales by Pfizer Inc. which is reported to the Company on a quarterly basis.

The primary procedures we performed to address this critical audit matter included:

•

•

•

•

•

•

•

Evaluating  management’s  significant  accounting  policies  related  to  the  Royalty  Purchase  Agreement  and  the  application  of  the  relevant
accounting guidance.

Vouching cash payments received from HCR to the Company during the year and through issuance of the consolidated financial statements.

Obtaining management’s forecast of future royalty sales by Pfizer Inc, including projections provided by a third-party specialist. Evaluating the
competency, expertise, and methodology used by such specialist.

Evaluating the reasonableness of significant assumptions used by management when developing the estimate of expected future royalties to be
paid, including future revenue royalty sales of Pfizer Inc.

Performing a retrospective review of historical projected royalty sales to actual results for reasonableness.

Evaluating the appropriateness of management’s method used to estimate the implied effective interest rate and the resulting non-cash interest
expense and liability recognized.  

Testing and recalculating the effective interest rate, non-cash interest expense, and the classification of the short-term and long-term liability on
the consolidated balance sheet.

Aptevo Therapeutics Inc.
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  of  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. 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, and satisfaction of liabilities, and commitments in the normal course of business. For the year ended December 31, 2021, we had a
net loss $28.5 million. We had an accumulated deficit of $214.1 million as of December 31, 2021. For the year ended December 31, 2021, net cash used in
our operating activities was $21.7 million. We have suffered recurring losses from operations and negative cash flows from operating activities. We believe
that our existing cash resources, the Investment Amount and Milestone Amounts related to Royalty Purchase Agreement with HCR, Purchase Agreement
with Lincoln Park, the cash to be generated from future deferred payments and milestones, and release of restricted cash securing letters of credit, funds
available to us from the remaining principal balance of 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 issuance of these financial statements. We may choose to raise additional funds to
support our operating and capital needs in the future.

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; 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  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

74

 
 
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 ongoing COVID-19 pandemic, we may experience delays or difficulties in
the financing environment and raising capital due to economic uncertainty.

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 Company currently operates in one operating segment, which is discovery and development of novel oncology
therapeutics.

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.

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

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.  

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,  forecasted  royalties,  effective  interest  rates,  clinical  accruals,  useful  lives  of  equipment,  commitments  and
contingencies,  and  stock-based  compensation.  Given  the  global  economic  climate  and  additional  or  unforeseen  effects  from  the  ongoing  COVID-19
pandemic, these estimates are becoming more challenging, and actual results could differ materially from those estimates.

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,  2021,  we  had  current  restricted  cash  of  $1.3  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.

75

 
 
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 consolidated statement of operations. 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.

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.

76

 
 
 
 
 
Debt Modification

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 to pay down the outstanding principal under the Credit Agreement from $25 million to $15 million. The amended Credit Agreement
was  accounted  for  under  ASC  470-50,  Debt  Modifications  and  Extinguishments  as  a  debt  modification,  rather  than  an  extinguishment,  based  on  a
comparison of the present value of the cash flows under the terms of the debt immediately before and after the amendment, which resulted in a change of
less than 10%. Unamortized issuance costs as of the date of modification will be amortized to interest expense using the effective interest method over the
repayment term.

Liability Related to Sale of Future Royalties and Non-Cash Interest Expense

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 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  2022,  2023,  and  2024  (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. The Company received a $10 million milestone payment in March 2022 and incurred
$0.5 million in transaction costs. The proceeds from the milestone, net of transaction costs, will be recorded as an additional liability related to the sale of
future royalties on the consolidated balance sheet in the first quarter of 2022. The Company is eligible to receive additional payments in aggregate of up to
$22.5 million based on achievement of sales milestones in 2023 and 2024.

We treat the Royalty Purchase Agreement with HCR (see Note 8) as a debt-like instrument, amortized under the effective interest rate method over
the  life  of  the  related  expected  royalty  stream.  The  liabilities  related  to  the  sale  of  future  royalties  and  the  debt  amortization  are  based  on  our  current
estimates of future royalties expected to be paid over the life of the arrangement. To the extent total future royalties collected are an amount less than the
liability, the Company is not obligated to fund any such shortfall. We will periodically assess the expected royalty payments using projections from external
sources.  To  the  extent  our  estimates  of  future  royalty  payments  are  greater  or  less  than  previous  estimates  or  the  estimated  timing  of  such  payments  is
materially  different  than  previous  estimates,  we  will  adjust  the  effective  interest  rate  and  recognize  related  non-cash  interest  expense  on  a  retrospective
basis. We are not obligated to repay the proceeds received under the Royalty Purchase Agreement with HCR. Due to our continuing involvement under the
Collaboration and License Agreement originally between Trubion and Wyeth, we continue to recognize royalty revenue on net sales of RUXIENCE and
record  the  royalty  payments  to  HCR  as  a  reduction  of  the  liability  when  paid.  As  such  payments  are  made  to  HCR,  the  balance  of  the  liability  will  be
effectively repaid over the life of the Royalty Purchase Agreement.

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 Aptevo’s preclinical 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 preclinical 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.

77

 
 
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 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  twenty-three  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  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.

78

 
 
 
 
 
 
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.

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  we  received  a  payment  in  March  2021  related  to  the  collection  of  a  certain  accounts  receivable,  and  the  sale  of  our  Aptevo
BioTherapeutics LLC business in February 2020.

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 rights, 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. We recorded a gain on sale in the quarter ended March 31, 2020.

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

Cash payment received
Escrow receivable

The  LLC  Purchase  Agreement  with  Medexus  entitles  us  to  future  deferred  payments  and  royalties.  For  the  year  ended  December  31,  2021,  we

collected an approximately $0.5 million deferred payment from Medexus related to IXINITY sales.

There was no amortization for Aptevo BioTherapeutics in the year ended December 31, 2021 and amortization was $0.1 million for the year ended
December  31,  2020.  Significant  operating  non-cash  items  include  the  gain  on  sale  of  Aptevo  BioTherapeutics  of  $14.3  million  for  the  year  ended
December 31, 2020. There were no significant investing non-cash items for the year ended December 31, 2021 and 2020.

Note 3. Collaboration Agreements

Alligator Bioscience AB

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 is a cost sharing agreement, there is no revenue.

For the years ended December 31, 2021 and December 31, 2020, we recorded approximately $0.1 million in our research and development expense

related to the collaboration arrangement.

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— 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,  2021  and  December  31,  2020,  we  had  $41.2  million  and  $35.4.  million  in  money  market  funds,  respectively.  The  carrying
amounts of our money market funds approximate their fair value. At December 31, 2021 and December 31, 2020, we did not have any Level 2 or Level 3
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 investments in money

market funds. Restricted cash, which are time deposits, includes $1.3 million securing letters of credit.

Note 7. Debt

Credit Agreement

On  February  28,  2020,  we  used  a  portion  of  the  proceeds  from  the  sale  of  Aptevo  BioTherapeutics  to  Medexus  to  fully  repay  $20  million
outstanding principal under the Credit and Security Agreement, including payment of $2.1 million in an end of facility fee, accrued interest, legal fees, and
prepayment  fees.  On  August  5,  2020,  we  entered  into  a  Credit  and  Security  Agreement  (the  Credit  Agreement),  with  MidCap  Financial.  The  Credit
Agreement provided us with up to $25.0 million of available borrowing capacity under a term loan facility. The full $25.0 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 Company’s assets are pledged as collateral under the terms of the Credit Agreement. The term loan facility includes additional repayment provisions
should  either  or  both  of  the  royalties  or  milestones  related  to  IXINITY  under  the  LLC  Purchase  Agreement  with  Medexus  or  royalties  related  to
RUXIENCE under the Royalty Purchase Agreement with HCR be sold during the term of the loan. The United Kingdom’s Financial Conduct Authority
(FCA),  which  regulates  LIBOR,  phased  out  one-week  and  two-month  US  Dollar  LIBOR  settings  on  December  31,  2021.  All  other  US  Dollar  LIBOR
settings, including the overnight, one-month, three-month, six-month and twelve-month, will be phased out on June 30, 2023. It is unclear if at that time
LIBOR will cease to exist or if new methods of calculating LIBOR will be established such that it continues to exist after 2023. Our Credit Agreement with
MidCap  Financial  currently  references  one-month  LIBOR  and  also  provides  that  we  may  amend  the  Credit  Agreement  to  reflect  an  alternative  rate  of
interest upon the phase out of LIBOR.

On November 6, 2020, Kevin Tang and his related entities filed a statement on Schedule 13D to report the purchase of 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 such Event
of Default 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 Credit Agreement.

On March 30, 2021, we amended our Credit Agreement with MidCap Financial and used $10.0 million of the proceeds received from the Royalty
Purchase Agreement to pay down the outstanding principal under the Credit Agreement from $25.0 million to $15.0 million. $10.0 million of the remaining
$15.0  million  principal  balance  will  be  payable  on  March  31,  2022.    Beginning  March  1,  2022,  monthly  repayment  of  the  remaining  $5.0  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 $5.0 million principal amount, under the

81

 
 
 
 
 
 
 
 
 
 
 
   
  
   
  
   
 
 
 
 
agreement  with  MidCap  Financial,  we  will  be  required  to  use  the  proceeds  from  the  sale  to  pay  down  the  outstanding  loan  principal  balance.  MidCap
Financial also released its security interest in the RUXIENCE royalty payments. A fee of $0.6 million was paid by the Company to MidCap Financial in
connection with the amendment in lieu of the formula-based fee previously required.

The amended Credit Agreement was accounted for as a debt modification, rather than an extinguishment, based on a comparison of the present
value of the cash flows under the terms of the debt immediately before and after the amendment, which resulted in a change of less than 10%. Unamortized
issuance costs as of the date of modification will be amortized to interest expense using the effective interest method over the repayment term.

As of December 31, 2021, we classified $11.7 million of the $15.0 million principal of the amended Credit Agreement to current portion of long-
term debt on the consolidated balance sheet. The amended Credit Agreement states that $10.0 million of the remaining $15.0 million principal balance will
be  payable  on  March  31,  2022.  Additionally,  within  the  next  twelve  months,  we  will  pay  $1.7  million  to  MidCap  Financial  for  monthly  repayments  of
outstanding principal beginning on March 1, 2022. For the years ended December 31, 2021 and 2020, the Company paid $1.4 million and $1.1 million in
interest expense pursuant to our Credit Agreement.

This facility is subject to a subjective acceleration clause that could be invoked by MidCap Financial upon the occurrence of any event MidCap

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

Future principal and interest payments in connection with the Credit Agreement as of December 31, 2021 are as follows:

Note 8. Liability Related to Sale of Future Royalties

In March 2021, we entered into and closed the Royalty Purchase Agreement with HCR pursuant to which we sold to HCR the right to receive
royalty  payments  made  by  Pfizer  in  respect  of  global  net  sales  of  RUXIENCE.  Under  the  terms  of  the  agreement,  we  received  $35.0  million  (the
Investment  Amount)  at  closing  and  we  are  eligible  to  receive  additional  payments  in  aggregate  of  up  to  an  additional  $32.5  million  based  on  the
achievement of sales milestones in 2022, 2023, and 2024 (collectively, the Milestone Amounts). The Royalty Purchase Agreement further provides that,
once  HCR  reaches  aggregate  royalty  payments  totaling  190%  of  the  amount  paid  at  closing  plus  Milestone  Amounts  to  the  extent  paid  by  HCR  to  the
Company, Aptevo will be entitled to receive 50% of royalty interest payments thereafter. The Company received a $10.0 million milestone payment in
March 2022 and incurred $0.5 million in transaction costs. The proceeds from the milestone, net of transaction costs, will be recorded as additional liability
related to sale of future royalties on the balance sheet in the first quarter of 2022. The Company is eligible to receive additional payments in aggregate of up
to $22.5 million based on achievement of sales milestones in 2023 and 2024.

The proceeds received from HCR of $35.0 million were recorded as a liability, net of transaction costs of $1.1 million, which will be amortized
over the estimated life of the arrangement using the effective interest method. In order to determine the amortization of the liability, we are required to
estimate  the  total  amount  of  future  royalty  payments  to  be  received  by  HCR  over  the  life  of  the  arrangement.  The  total  amount  of  royalty  payments
received by HCR under the Royalty Purchase Agreement, less the net proceeds we received of $33.9 million, is recorded as non-cash interest expense over
the  life  of  the  arrangement  using  the  effective  interest  method.  We  maintain  our  rights  under  the  Definitive  Agreement  originally  between  Trubion  and
Wyeth,  with  the  exception  of  the  cash  flows  of  the  RUXIENCE  royalty  payments  purchased  by  HCR.  Due  to  our  continuing  involvement  under  the
Definitive Agreement originally between Trubion and Wyeth, we continue to recognize royalty revenue on net sales of RUXIENCE and record the royalty
payments to HCR as a reduction of the liability when paid. As such payments are made to HCR, the balance of the liability will be effectively repaid over
the life of the Royalty Purchase Agreement. To the extent total future royalties collected are an amount less than the liability, the Company is not obligated
to fund any such shortfall.

82

 
 
 
 
 
   
   
 
 
We estimate the effective interest rate used to record non-cash interest expense under the Royalty Purchase Agreement based on the estimate of
future royalty payments to be received by HCR. As of December 31, 2021, the estimated effective interest rate under the agreement was 23.0%. Over the
life of the arrangement, the actual effective interest rate will be affected by the amount and timing of the royalty payments received by HCR and changes in
our forecasted royalties. Periodically, we will reassess our estimate of total future royalty payments to be received by HCR, and retrospectively adjust the
effective interest rate and amortization of the liability as necessary.

The following table presents the changes in the liability in the year related to the sale of future royalties under the Royalty Purchase Agreement

with HCR (in thousands):

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,  2021  and  December  31,  2020,  we  recorded  $0.8  million  and  $0.7  million,  respectively,  related  to  variable

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

 Equipment Leases - Operating

As of December 31, 2021, 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, 2021, 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, 2021.

The long-term portion of the lease liabilities included in the amounts above is $1.3 million and the remainder of our lease liabilities are included in

other current liabilities on our consolidated balance sheets.

As of December 31, 2021, the weighted average remaining lease term and weighted discount rate for operating leases was 1.3 years and 14.46%.

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%.

Note 10. Net Income (Loss) per Share

Basic net income (loss) per share is calculated by dividing the net income (loss) by the weighted average number of common shares outstanding for
the period. Diluted net income (loss) per share is computed by dividing the net income (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 (loss) 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 Company issued warrants to purchase shares of our common stock outstanding related to our March 11, 2019 public offering. For the years
ended December 31, 2021 and 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 54,105 and 1,166,735 shares of the Company’s common stock and aggregate proceeds to the Company of
approximately $1.0 million and $21.2 million, respectively. As of December 31, 2021, and December 31, 2020, there were warrants to purchase 350,589
and 404,694 shares of our common stock outstanding, respectively.

For the year ended December 31, 2021, we did not issue any common stock due to the vesting of RSUs. For the year ended December 31, 2020, we

issued 9,206 of common stock due to the vesting of RSUs.

For the years ended December 31, 2021 and December 31, 2020, we received proceeds of $0.2 million and $0.02 million upon the exercise of stock

options which resulted in the issuance of 26,082 and 2,158 shares of common stock, respectively.

Lincoln Park Purchase Agreement

On December 20, 2018, we entered into a Purchase Agreement, and a registration rights agreement, with Lincoln Park (the Purchase Agreement).
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.

For the year ended December 31, 2021, the Company issued 407,047 shares of common stock to Lincoln Park under the 2018 Purchase Agreement.
We received $10.2 million in proceeds from issuance of these shares over the three-year period. The Company did not issue any shares of common stock to
Lincoln Park under the Purchase Agreement for the year ended December 31, 2020. Our 2018 Purchase Agreement and Registration Rights Agreement
with Lincoln Park expired in March 2022.

On February 16, 2022, the Company entered into a new Purchase Agreement and a Registration Rights Agreement with Lincoln Park. Under the
new Purchase Agreement, Lincoln Park committed to purchase up to $35.0 million worth of our common stock over a 36-month period commencing after
the  satisfaction  of  certain  conditions  set  forth  in  the  Purchase  Agreement.  The  purchase  price  per  share  will  be  based  off  of  prevailing  market  price;
provided, however, that the prevailing market price is not below $1.00. The Company agreed to issue 99,276 shares of our common stock to Lincoln Park
for no cash consideration as an initial fee for its commitment to purchase shares of our common stock under the Purchase Agreement.

Rights Plan

On November 8, 2020, our Board of Directors (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. The Rights Agreement was amended on November 4, 2021 to extend the expiration date
of such agreement from November 8, 2021 to November 5, 2022.

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 2021.

Converted Equity Awards Incentive Plan

In  connection  with  the  spin-off  from  Emergent  in  August  2016,  we  adopted  the  Converted  Equity  Awards  Incentive  Plan  (Converted  Plan)  and
outstanding equity awards of Emergent held by Aptevo employees were converted into or replaced with equity awards of Aptevo (Conversion Awards). A
total of 0.1 million shares of Aptevo common stock have been authorized for issuance under the Converted Plan.

86

 
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.

On  May  31,  2017,  at  the  2017  Annual  Meeting  of  Stockholders  (Annual  Meeting),  the  Company’s  stockholders  approved  the  amendment  and
restatement  of  the  Company’s  2016  SIP  (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 of the Stockholders, the Company’s stockholders approved a new 2018 Stock Incentive Plan (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
have been and will be issued out of the 2018 SIP, which has 0.3 million shares of Aptevo common stock authorized for issuance. The 2018 Plan became
effective immediately upon stockholder approval at the 2018 Annual Meeting of the Stockholders. 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 Plan (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.  As  of  December  31,  2021,  there  are  less  than  0.1  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

Stock-based  compensation  expense  includes  amortization  of  stock  options  and  RSUs  granted  to  employees  and  non-employees  and  has  been

reported in our consolidated statements of operations as follows:

The  Company  accounts  for  stock-based  compensation  by  measuring  the  cost  of  employee  services  received  in  exchange  for  all  equity  awards
granted  based  on  the  fair  value  of  the  award  as  of  the  grant  date.  The  Company  recognizes  the  compensation  expense  over  the  vesting  period.  All
assumptions used to calculate the grant date fair value of nonemployee options are generally consistent with the assumptions used for options granted to
employees. In the event the Company terminates any of its consulting agreements, the unvested options underlying the agreements would also be cancelled.

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

As of December 31, 2021, we had $3.4 million of unrecognized compensation expense related to options expected to vest over a weighted average
period of 2.1 years. The weighted average remaining contractual life of outstanding and exercisable options is 8.2 years. For the year ended December 31,
2021, 81,146 shares were forfeited, compared to 325,904 shares forfeited in the year ended December 31, 2020. The weighted-average grant date fair value
per share of options granted during the years ended December 31, 2021 and 2020 was $23.02 and $5.32, respectively. The total intrinsic value of options
exercised for the years ended December 31, 2021 and 2020 was $0.4 million and $0.1 million, respectively. The total fair value of stock options vested for
the years ended December 31, 2021 and 2020 was $1.6 million and $0.9 million, respectively.

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 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 the last trading day of the year.

As  of  December  31,  2021,  we  had  $1.4  million  of  unrecognized  stock-based  compensation  expense  related  to  RSUs  expected  to  vest  over  a

weighted average period of 2.2 years.

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

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, all of 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.  These  are  therefore  included
within  equity  on  our  consolidated  balance  sheets.  For  the  years  ended  December  31,  2021  and  December  31,  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  54,105  and  1,166,735  shares  of  the
Company’s  common  stock  and  aggregate  proceeds  to  the  Company  of  approximately  $1.0  million  and  $21.2  million,  respectively.  As  of  December  31,
2021, and December 31, 2020, there were warrants to purchase 350,589 and 404,694 shares of our common stock outstanding, respectively.

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,  2021  and  December  31,  2020,  Aptevo’s  related  share  of  matching  contributions  was  approximately  $0.2  million  and  $0.3  million,
respectively.

Note 13. Income Taxes

We did not have an income tax benefit or income tax expense from continuing operations in the years ended December 31, 2021 and December 31,

The  Company  evaluated  the  positive  and  negative  evidence  bearing  upon  the  realizability  of  its  deferred  tax  assets.  Based  on  the  Company’s
history of operating losses, including a three-year cumulative loss position as of December 31, 2021, the Company has concluded that it is more likely than
not that the benefit of its deferred tax assets will not be realized. Accordingly, the Company provided a full valuation allowance for its net deferred tax
assets as of December 31, 2021 and 2020. The valuation allowance increased by $6.0 million during the year ended December 31, 2021. The increase in the
valuation  allowance  during  the  year  ended  December  31,  2021  was  due  primarily  to  an  increase  in  deferred  tax  assets  resulting  from  the  sale  of  the
Company’s RUXIENCE royalty rights to HCR, which was treated as a sale for tax purposes, orphan drug credit generated during the period, and stock-
based compensation expense, the impact of which was partially offset by the utilization of federal and state NOLs during the period.

As  of  December  31,  2021,  and  2020,  we  have  recorded  federal  net  operating  losses  (NOL)  carryforwards  of  approximately  $159.6  million  and
$162.5 million, state NOL carryforwards of approximately $70.3 million and $68.1 million, and tax credit carryforwards of $3.3 million and $2.2 million,
respectively. Approximately $38.0 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 2021. 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.

On March 8, 2022, the Company received a $10 million milestone payment from HCR pursuant to our Royalty Purchase Agreement. We incurred
$0.5 million in transaction costs related to the milestone payment. Proceeds from the milestone payment, net of transaction costs, will be recorded as a
liability related to sale of future royalties on the balance sheet in the first quarter of 2022. Consistent with our initial accounting for the Royalty Purchase
Agreement,  the  milestone  payment  was  accounted  for  as  debt-like  instrument  within  the  scope  of  ASC  470-20-25,  Debt – Sales of Future Revenues or
Various  Other  Measures  of  Income  and  will  be  amortized  over  the  life  of  the  arrangement.  The  Company  is  eligible  to  receive  additional  payments  in
aggregate of up to $22.5 million based on achievement of sales milestones in 2023 and 2024.

On February 16, 2022, the Company entered into a new Purchase Agreement and a Registration Rights Agreement with Lincoln Park to replace our
initial Purchase Agreement and Registration Rights Agreement from 2018. Under the new Purchase Agreement, Lincoln Park committed to purchase up to
$35.0  million  worth  of  our  common  stock  over  a  36-month  period  commencing  after  the  satisfaction  of  certain  conditions  set  forth  in  the  Purchase
Agreement. The purchase price per share will be based off of prevailing market price; provided, however, that the prevailing market price is not below
$1.00. The Company agreed to issue 99,276 shares of our common stock to Lincoln Park for no cash consideration as an initial fee for its commitment to
purchase shares of our common stock under the Purchase Agreement.

Item 9A. Controls and Procedures.

Evaluation of Disclosure Controls and Procedures

As of December 31, 2021, 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, 2021, 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, 2021 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,  2021,  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 quarter ended December 31, 2021, 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.

Item 9B. Other Information.

On March 21, 2022, the Board of Directors of the Company approved the Amended and Restated Senior Management Severance Plan (the “Plan”),
which became effective on March 23, 2022. Among other changes, the Plan was modified to reinstate the percentage of compensation payable to Executive
Vice Presidents that existed in a previous Senior Management Severance Plan. In the event of termination in connection without cause (as defined in the
Plan), Executive Vice Presidents will receive 125% of such participant’s base salary plus target bonus for a period of 15 months and 200% of base salary
plus target bonus for termination without cause related to a change of control (as defined in the Plan).

 (a)

Anything in this Plan to the contrary notwithstanding and except as set forth below, in the event it shall be determined that any
Payment would be subject to the Excise Tax, then the Participant shall have the following two options:

(i)  if a reduction in benefits to a Value equivalent to the Safe Harbor Amount would result in an increase in the Payments
that would be retained by Participant, net of all applicable taxes, Participant may choose to reduce the amount of the
payments made pursuant to this Plan to the Safe Harbor Amount, or

(ii)  in the event that Participant decides not to reduce the amount of Payments to the Safe Harbor Amount pursuant to
Section 6(a)(i), Participant may choose to be solely responsible for the payment of all taxes, including any Excise
Taxes, that become due thereon. The reduction of amounts payable pursuant to Section 6(a)(i), if applicable, shall be
made, as determined by the Company, in the following order: (A) any cash payments, (B) any taxable benefits, (C) any
nontaxable benefits, and (D) any vesting of equity awards, in each case in reverse order beginning with payments or
benefits that are to be paid the farthest in time from the date that triggers the applicability of the Excise Tax, to the
extent necessary to maximize the Value of all Payments actually made to the Participant. For purposes of reducing the
Payments to the Safe Harbor Amount, only amounts payable under this Plan (and no other Payments) shall be reduced.

 (b)

All determinations required to be made under this Section 6, including the amount of such Excise Tax and the assumptions to be
utilized to assist Participant with determining his/her options under Section 6(a), shall be made by such certified public accounting
firm as may be designated by the Company (the “Accounting Firm”), which shall provide detailed supporting calculations both to
the Company and the Participant as is requested by the Company. All fees and expenses of the Accounting Firm shall be borne
solely by the Company. Any determination by the Accounting Firm shall be binding upon the Company and the Participant.

 (c)  

The following terms shall have the meanings below for purposes of this Section 6.

(i)  “Excise Tax” shall mean the excise tax imposed by Section 4999 of the Code, together with any interest or penalties

Section 280G of the Code of the portion of such Payment that constitutes a “parachute payment” under

Excise Tax will apply to such Payment.

(iii)  A “Payment” shall mean any payment or distribution in the nature of compensation (within the meaning of

Section 280G(b)(2) of the Code) to or for the benefit of the Participant, whether paid or payable pursuant to this Plan or
otherwise.

(iv)  The “Safe Harbor Amount” means 2.99 times the Participant’s “base amount,” within the meaning of Section 280G(b)

purposes of Section 280G of the Code, as determined by the Accounting Firm using the discount rate required by

payment or benefit provided for under this Plan by seeking other employment or otherwise, nor shall the amount of any payment or benefit provided for
hereunder be reduced by any compensation or benefits earned or received by such Participant as the result of employment by a subsequent employer, by
retirement benefits, by offset against any amount claimed to be owed by such Participant to the Company or otherwise.

Section 8. Validity. The invalidity or unenforceability of any provision of this Plan shall not affect the validity or enforceability of any other provision of
this Plan, which other provision shall remain in full force and effect.

Section 9. Withholding. All payments hereunder shall be reduced by any applicable taxes required by applicable law to be paid or withheld by the
Company.

Section 10. Modification or Waiver. The Board may amend, modify, or terminate the Plan at any time in its sole discretion; provided, however, that (a) any
such amendment, modification or termination that adversely affects the rights of any Participant shall be unanimously approved by the Board and
consented to in writing by such Participant, (b) no such amendment, modification or termination may affect the rights of a Participant then receiving
payments or benefits under the Plan without the consent in writing of such Participant and (c) no such amendment, modification or termination made after a
Change of Control shall be effective for at least eighteen (18) months following the closing of the Change of Control.

Section 11. Applicable Law. This Plan shall be governed by and construed in accordance with the laws of the State of Delaware, without regard to conflicts
of laws principles thereof.

Section 12. Administration of Plan. This Plan will be administered by the Board. The Board shall have authority to adopt, amend and repeal such

administration, operation and implementation of the Plan, including without limitation any changes made to the definition Good Reason, in establishing the
list of Participants, or in selecting the Participants to be included in any of the Appendices attached to this Plan. No amounts paid under this Section 12 for

Section 13. Payments Subject to Section 409A.

 (a)

Subject to the provisions in this Section 13, any severance payments or benefits under the Plan shall begin only upon the date of the
Participant’s “separation from service” (as determined below), which occurs on or after the date of the Participant’s termination of
employment.  The following rules shall apply with respect to distribution of the severance payments and benefits, if any, to be
provided to the Participant under this Plan:

(i)   It is intended that each installment of the severance payments and benefits provided under this Plan shall be treated as

a separate “payment” for purposes of Section 409A of the Code and the guidance issued thereunder (“Section
409A”).  Neither the Participant nor the Company shall have the right to accelerate or defer the delivery of any such
payments or benefits except to the extent specifically permitted or required by Section 409A.

(ii)  If, as of the date of the Participant’s “separation from service” from the Company (within the meaning of Section 13(a)
(iv) below), the Participant is not a “specified employee” (within the meaning of Section 409A), then each installment
of the severance payments and benefits shall be made on the dates and terms set forth in this Plan.

(iii)  If, as of the date of the Participant’s “separation from service” from the Company, the Participant is a “specified

employee” (within the meaning of Section 409A), then:

A.   Each installment of the severance payments and benefits due under this Plan that, in accordance

with the dates and terms set forth herein, will in all circumstances, regardless of when the
separation from service occurs, be paid within the short-term deferral period (as defined under
Section 409A) shall be treated as a short-term deferral within the meaning of Treasury Regulation
Section 1.409A-1(b)(4) to the maximum extent permissible under Section 409A and shall be made
on the dates and terms set forth in this Plan; and

B.  Each installment of the severance payments and benefits due under this Plan that is not described
in Section 13(a)(iii)(A) above and that would, absent this subsection, be paid within the six-month
period following the Participant’s “separation from service” from the Company shall not be paid
until the date that is six months and one day after such separation from service (or, if earlier, the
Participant’s death), with any such installments that are required to be delayed being accumulated
during the six-month period and paid in a lump sum on the date that is six months and one day
following the Participant’s separation from service and any subsequent installments, if any, being
paid in accordance with the dates and terms set forth herein; provided, however, that the preceding
provisions of this sentence shall not apply to any installment of severance payments and benefits if
and to the maximum extent that that such installment is deemed to be paid under a separation pay
plan that does not provide for a deferral of compensation by reason of the application of Treasury
Regulation Section 1.409A-1(b)(9)(iii) (relating to separation pay upon an involuntary separation
from service).  Any installments that qualify for the exception under Treasury Regulation Section
1.409A-1(b)(9)(iii) must be paid no later than the last day of the Participant’s second taxable year
following the taxable year in which the separation from service occurs.

 
 
 
 
 
 
 
 
 
(iv)  The determination of whether and when the Participant’s separation from service from the Company has occurred shall
be made in a manner consistent with, and based on the presumptions set forth in, Treasury Regulation Section 1.409A-
1(h).  Solely for purposes of this Section 13(a)(iv), “Company” shall include all persons with whom the Company
would be considered a single employer as determined under Treasury Regulation Section 1.409A-1(h)(3).

 (b)

 (c)

 (d)

All reimbursements and in-kind benefits provided under this Plan shall be made or provided in accordance with the requirements of
Section 409A to the extent that such reimbursements or in-kind benefits are subject to Section 409A, including, where applicable,
the requirement that (i) any reimbursement is for expenses incurred during the Participant’s lifetime (or during a shorter period of
time specified in this Plan), (ii) the amount of expenses eligible for reimbursement during a calendar year may not affect the
expenses eligible for reimbursement in any other calendar year, (iii) the reimbursement of an eligible expense will be made on or
before the last day of the calendar year following the year in which the expense is incurred and (iv) the right to reimbursement is
not subject to set off or liquidation or exchange for any other benefit.

The Company makes no representation or warranty and shall have no liability to the Participants or any other person if any
provisions of this Plan are determined to constitute deferred compensation subject to Section 409A and do not satisfy an exemption
from, or the conditions of, Section 409A.

The Plan and the Payments hereunder are intended to comply with or be exempt from Section 409A, and the Plan shall be
interpreted consistent with the provisions of Section 409A.

This Plan supersedes and replaces any severance benefit plan, policy, agreement or practice of or with the Company regarding the subject nature hereof,
including, but not limited to the Amended Senior Management Severance Plan approved by the Board on August 10, 2020.

Adopted by Aptevo Therapeutics Inc. this 23rd day of March, 2022.
