are subject to various known and unknown risks and uncertainties and SIGA cautions you that any forward-looking information provided by or on behalf of
SIGA is not a guarantee of future performance. SIGA’s actual results could differ materially from those anticipated by such forward-looking statements due
to a number of factors, some of which are beyond SIGA’s control, including, but not limited to, (i) the risk that BARDA elects, in its sole discretion as
permitted under the BARDA Contracts, not to exercise all, or any, of the remaining unexercised options under those contracts, (ii) the risk that SIGA may

clinical trials, (vi) the risk that SIGA or its collaborators will not obtain appropriate or necessary governmental approvals to market these or other potential
products  or  uses,  (vii)  the  risk  that  SIGA  may  not  be  able  to  secure  or  enforce  sufficient  legal  rights  in  its  products,  including  intellectual  property
protection, (viii) the risk that any challenge to SIGA’s patent and other property rights, if adversely determined, could affect SIGA’s business and, even if
determined  favorably,  could  be  costly,  (ix)  the  risk  that  regulatory  requirements  applicable  to  SIGA’s  products  may  result  in  the  need  for  further  or
additional testing or documentation that will delay or prevent seeking or obtaining needed approvals to market these products, (x) the risk that the volatile
and competitive nature of the biotechnology industry may hamper SIGA’s efforts to develop or market its products, (xi) the risk that changes in domestic or
foreign economic and market conditions may affect SIGA’s ability to advance its research or may affect its products adversely, (xii) the effect of federal,
state,  and  foreign  regulation,  including  drug  regulation  and  international  trade  regulation,  on  SIGA’s  businesses  and  (xiii)  the  risk  that  the  U.S.
Government’s  responses  (including  inaction)  to  the  national  or  global  economic  situation  or  infectious  disease  such  as  COVID-19  may  affect  SIGA’s
business adversely, as well as the risks and uncertainties included in Item 1A “Risk Factors” of this Form 10-K. All such forward-looking statements are

Item 1. Business

Overview

SIGA Technologies, Inc. is referred to throughout this report as “SIGA,” “the Company,” “we” or “us.”

We  are  a  commercial-stage  pharmaceutical  company.  Our  lead  product,  TPOXX®  (“oral  TPOXX®”),  is  a  U.S.  Food  &  Drug  Administration

("FDA")-approved oral formulation antiviral drug for the treatment of human smallpox disease caused by variola virus. 

BARDA Contracts-TPOXX®

19C BARDA Contract

On  September  10,  2018,  the  Company  entered  into  a  contract  with  the  U.S.  Biomedical  Advanced  Research  and  Development  Authority
("BARDA")  pursuant  to  which  SIGA  agreed  to  deliver  up  to  1,488,000  courses  of  oral  TPOXX®  to  the  U.S.  Strategic  National  Stockpile  ("Strategic
Stockpile"), and to manufacture and deliver to the Strategic Stockpile, or store as vendor-managed inventory, up to 212,000 courses of the intravenous (IV)
formulation of TPOXX® (“IV TPOXX®”). Additionally, the contract includes funding from BARDA for advanced development of IV TPOXX®, post-
marketing activities for oral and IV TPOXX®, and procurement activities. As of December 31, 2020, the contract with BARDA (as amended, modified, or
supplemented  from  time  to  time,  the  "19C  BARDA  Contract")  contemplates  up  to  approximately  $602.5  million  of  payments,  of  which  approximately
$51.7  million  of  payments  are  included  within  the  base  period  of  performance  of  five  years,  approximately  $127.1  million  of  payments  are  related  to
exercised  options  and  up  to  approximately  $423.7  million  of  payments  are  currently  specified  as  unexercised  options.  BARDA  may  choose  in  its  sole
discretion when, or whether, to exercise any of the unexercised options. The period of performance for options is up to ten years from the date of entry into
the 19C BARDA Contract and such options could be exercised at any time during the contract term, including during the base period of performance. 

Table of Contents

2

The  base  period  of  performance  specifies  potential  payments  of  approximately  $51.7  million  for  the  following  activities:  payments  of
approximately $11.1 million for the delivery of approximately 35,700 courses of oral TPOXX® to the Strategic Stockpile; payments of $8.0 million for the
manufacture of 20,000 courses of final drug product of IV TPOXX® ("IV FDP"), of which $3.2 million of payments are related to the manufacture of bulk
drug  substance  ("IV  BDS")  to  be  used  in  the  manufacture  of  IV  FDP;  payments  of  approximately  $32.0  million  to  fund  advanced  development  of  IV
TPOXX®; and payments of approximately $0.6 million for supportive procurement activities. As of December 31, 2020, the Company had received or
billed  for  $11.1  million  for  the  successful  delivery  of  approximately  35,700  courses  of  oral  TPOXX®  to  the  Strategic  Stockpile,  $3.2  million  for  the
manufacture of IV BDS and $9.7 million for other base period activities. IV BDS is expected to be used for the manufacture of 20,000 courses of IV FDP.
The $3.2 million received for the manufacture of IV BDS has been recorded as deferred revenue as of December 31, 2020 and December 31, 2019; such
amount is expected to be recognized as revenue when IV TPOXX® containing such IV BDS is delivered to the Strategic Stockpile or placed in vendor-
managed inventory.

The  options  that  have  been  exercised  to  date  provide  for  payments  up  to  approximately  $127.1  million.  There  are  exercised  options  for  the
following activities: payments up to $11.2 million for the procurement of raw materials to be used in the manufacture of at least 363,070 courses of oral
TPOXX®, payments up to $101.3 million for the delivery of up to 363,070 courses of oral TPOXX®; and, payments of up to $14.6 million for funding of
post-marketing activities for oral TPOXX®. As of December 31, 2020, the Company has received the following payments in connection with exercised
options: $11.2 million was received for the procurement of raw materials and such amount was initially recorded as deferred revenue and was recognized
as revenue during the year ended December 31, 2020, with deliveries of approximately 363,000 courses, in the aggregate, of oral TPOXX®; $101.3 million
was received in connection with the June, September and October deliveries, in total, of approximately 363,000 courses of oral TPOXX®; and $5.4 million
has been received or billed for in connection with post-marketing activities for oral TPOXX®.

Unexercised options specify potential payments up to approximately $423.7 million in total (if all such options are exercised). There are options
for the following activities: payments of up to $337.7 million for the delivery of up to approximately 1,089,000 courses of oral TPOXX® to the Strategic
Stockpile; payments of up to $76.8 million for the manufacture of up to 192,000 courses of IV FDP, of which up to $30.7 million of payments would be
paid upon the manufacture of IV BDS to be used in the manufacture of IV FDP; payments of up to approximately $3.6 million to fund post-marketing
activities for IV TPOXX®; and payments of up to approximately $5.6 million for supportive procurement activities.

The options related to IV TPOXX® are divided into two primary manufacturing steps. There are options related to the manufacture of bulk drug
substance (“IV BDS Options”), and there are corresponding options (for the same number of IV courses) for the manufacture of final drug product (“IV
FDP Options”). BARDA may choose to exercise any, all, or none of these options in its sole discretion. The 19C BARDA Contract includes: three separate
IV  BDS  Options,  each  providing  for  the  bulk  drug  substance  equivalent  of  64,000  courses  of  IV  TPOXX®;  and  three  separate  IV  FDP  Options,  each
providing  for  64,000  courses  of  final  drug  product  of  IV  TPOXX®.  BARDA  has  the  sole  discretion  as  to  whether  to  simultaneously  exercise  IV  BDS
Options and IV FDP Options, or whether to exercise options at different points in time (or alternatively, to only exercise the IV BDS Option but not the IV
FDP  Option).  If  BARDA  decides  to  only  exercise  IV  BDS  Options,  then  the  Company  would  receive  payments  up  to  $30.7  million;  alternatively,  if
BARDA decides to exercise both IV BDS Options and IV FDP Options, then the Company would receive payments up to $76.8 million. For each set of
options relating to a specific group of courses (for instance, the IV BDS and IV FDP options that reference the same 64,000 courses), BARDA has the
option to independently purchase IV BDS or IV FDP. The Company estimates that sales of the IV formulation under this contract (under current terms),
assuming the IV FDP Options were exercised, would have a gross margin (sales less cost of sales, as a percentage of sales) that is less than 40%.

Under the terms of this contract, exercise of procurement options are at the sole discretion of BARDA. The request for proposal that preceded the
award of the 19C BARDA Contract indicated that the expected purpose of the contract was to maintain the level of smallpox antiviral preparedness in the
Strategic  Stockpile.  Based  on  prior  product  delivery  activity,  and  current  FDA-approved  shelf  life  of  oral  TPOXX®,  the  Company  estimates  that
approximately one million courses of smallpox antiviral treatment would need to be delivered to the U.S. Government between 2021 and 2023 in order to
maintain stockpile levels of unexpired smallpox antiviral treatment during this period.       

2011 BARDA Contract

 
 
 
 
 
 
 
 
 
 
 
 
 
 
On May 13, 2011, the Company signed a contract with BARDA pursuant to which BARDA agreed to buy from the Company 1.7 million courses

of oral TPOXX®. Additionally, the Company agreed to contribute to BARDA 300,000 courses at no additional cost to BARDA.

Table of Contents

The contract with BARDA (as amended, modified, or supplemented from time to time the "2011 BARDA Contract”) includes a base contract, as
modified,  (“2011  Base  Contract”)  as  well  as  options.  The  2011  Base  Contract  specifies  approximately  $508.4  million  of  payments  (including  exercised
options), of which, as of December 31, 2020, $459.8 million has been received by the Company for the manufacture and delivery of 1.7 million courses of
oral TPOXX® and $45.6 million has been received for certain reimbursements in connection with development and supportive activities. Approximately
$3.0 million remains eligible to be received in the future for reimbursements of development and supportive activities.

For courses of oral TPOXX® that have been physically delivered to the Strategic Stockpile under the 2011 BARDA Contract, there are product
replacement  obligations,  including:  (i)  a  product  replacement  obligation  in  the  event  that  the  final  version  of  oral  TPOXX®  approved  by  the  FDA  was
different  from  any  courses  of  oral  TPOXX®  that  had  been  delivered  to  the  Strategic  Stockpile  (the  "FDA  Approval  Replacement  Obligation");  (ii)  a
product  replacement  obligation,  at  no  cost  to  BARDA,  in  the  event  that  oral  TPOXX®  is  recalled  or  deemed  to  be  recalled  for  any  reason;  and  (iii)  a
product  replacement  obligation  in  the  event  that  oral  TPOXX®  does  not  meet  any  specified  label  claims.  On  July  13,  2018,  the  FDA  approved  oral
TPOXX®  for  the  treatment  of  smallpox  and  there  is  no  difference  between  the  approved  product  and  courses  in  the  Strategic  Stockpile.  As  such,  the
possibility of the FDA Approval Replacement Obligation resulting in any future replacements of product within the Strategic Stockpile is remote.

The  2011  BARDA  Contract  includes  options.  On  July  30,  2018,  the  2011  BARDA  Contract  was  modified  and  BARDA  exercised  its  option
relating to FDA approval of the aforementioned 84-month expiry for oral TPOXX® for which the Company was paid $50.0 million in August 2018. With
the  option  exercise,  the  2011  BARDA  Contract  was  modified  so  that  the  2011  Base  Contract  increased  by  $50.0  million.  Remaining  options,  if  all
were  exercised  by  BARDA,  would  result  in  aggregate  payments  to  the  Company  of  $72.7  million,  including  up  to  $58.3  million  of  funding  for
development and supportive activities such as work on a post-exposure prophylaxis ("PEP") indication for TPOXX® and/or $14.4 million of funding for
production-related activities related to warm base manufacturing. BARDA may choose, in its sole discretion not to exercise any or all of the unexercised
options. In 2015, BARDA exercised two options related to extending the indication of the drug to the geriatric and pediatric populations. The stated value
of those exercises was immaterial.

The 2011 BARDA Contract expires in December 2024.

International Procurement Contracts

Contract with Public Health Agency of Canada

On January 13, 2021, the Public Health Agency of Canada ("PHAC") awarded a contract to Meridian Medical Technologies, Inc. (“Meridian,” a Pfizer
Company) (the “Contract”) for the purchase of up to approximately $33 million of oral TPOXX® (tecovirimat) within five years. The Contract specifies
firm  commitments  for  the  purchase  of  approximately  $3.4  million  of  oral  TPOXX®  to  occur  by  March  31,  2021  and  a  cumulative  purchase  of
approximately $17 million of oral TPOXX® by March 31, 2023; the remaining courses under the Contract are targeted for delivery after March 31, 2023
and are subject to option exercise by PHAC. To date, SIGA has not finalized any deliveries yet in connection with this contract. The contract award was
coordinated  between  SIGA  and  Meridian  under  an  international  promotion  agreement,  as  amended  (the  "International  Promotion  Agreement")  that  was
entered into by the parties on June 3, 2019. As such, Meridian is the PHAC's counterparty under the Contract, and SIGA is responsible for manufacture and
delivery of any oral TPOXX® purchased thereunder. 

Canadian Military Contract

On April 3, 2020, the Company announced that the Canadian Department of National Defence (“CDND”) awarded a contract (the "Canadian Military
Contract")  to  Meridian,  pursuant  to  which  the  CDND  will  purchase  up  to  approximately  $14  million  of  oral  TPOXX®  over  four  years.    In  the  second
quarter 2020, CDND purchased $2.3 million of oral TPOXX®.  The remaining purchases are at the option of the CDND, and are expected to occur after
regulatory approval of oral TPOXX® in Canada. Meridian is the CDND's counterparty under the Canadian Military Contract, and SIGA is responsible for
manufacture and delivery of any oral TPOXX® purchased thereunder. 

International Promotion Agreement

Under the terms of the International Promotion Agreement, Meridian was granted exclusive rights to market, advertise, promote, offer for sale, or sell
oral TPOXX® in a field of use specified in the International Promotion Agreement in all geographic regions except for the United States (the “Territory”),
and Meridian has agreed not to commercialize any competing product, as defined in the International Promotion Agreement, in the specified field of use in
the Territory. SIGA will retain ownership, intellectual property, distribution and supply rights and regulatory responsibilities in connection with TPOXX®,
and, in the United States market, will also retain sales and marketing rights with respect to oral TPOXX®. SIGA’s consent shall be required for the entry
into any sales arrangement pursuant to the International Promotion Agreement.

The fee Meridian retains pursuant to the International Promotion Agreement will be a specified percentage of the collected proceeds of sales of oral
TPOXX® net of certain expenses, for years in which customer invoiced amounts net of such expenses are less than or equal to a specified threshold, and a
higher  specified  percentage  of  such  collected  net  proceeds  for  years  in  which  such  net  invoiced  amounts  exceed  the  specified  threshold.    Taking  into
account Meridian’s fee and manufacturing costs of oral TPOXX®, it is currently estimated by the Company that international sales of oral TPOXX® will
have a contribution margin (as expressed as a percentage of product sales, and before any consideration of expenses not directly related to manufacturing or
Meridian activities) of between approximately 65% and 80%.

SIGA  believes  that  TPOXX®  is  among  the  first  new  small-molecule  drugs  delivered  to  the  Strategic  Stockpile  under  Project  BioShield.  Oral
TPOXX® is a novel, patented drug that is easy to store, transport and administer. On July 13, 2018, the FDA approved oral TPOXX® for the treatment of
smallpox. Oral TPOXX® labeling, approved by the FDA, limits sales of oral TPOXX® in the U.S. to those for the Strategic Stockpile. Under the 2011
BARDA Contract, 1.7 million courses of oral TPOXX® were sold to BARDA and delivered to the Strategic Stockpile between 2013 and 2017. Courses
delivered under the 2011 BARDA Contract have an FDA-approved shelf life of seven years. Under the 19C BARDA Contract, SIGA can deliver up to 1.7
million courses of TPOXX® (of which 1,488,000 courses would be oral TPOXX® and 212,000 courses would be IV TPOXX®) to the Strategic Stockpile,
at the option of BARDA.

For IV TPOXX®, SIGA expects to file a new drug application ("NDA") for IV TPOXX® as early as during the second quarter of 2021. Based on
its review of the NDA, the FDA will decide whether to approve IV TPOXX® and whether to impose any marketing restrictions or require additional post-
approval clinical studies. This review process will typically take ten months. There can be no assurance that any approval will be granted on a timely basis,
if at all.

As noted above, the FDA approved oral TPOXX® for the treatment of smallpox. The Company is currently seeking regulatory approval of oral
TPOXX® in Europe and Canada as well. In July 2020, the Company filed a Marketing Authorisation Application ("MAA") with the European Medicines
Agency ("EMA") for oral tecovirimat, the same formulation that was approved by the FDA in July 2018 under the name TPOXX®.  The MAA was filed
under  the  centralized  application  process,  which,  upon  approval,  will  enable  sales  and  marketing  of  oral  tecovirimat  in  all  EU  member  states,  as  well
as  Norway,  Iceland,  and  Liechtenstein.    SIGA  has  filed  its  application  for  oral  tecovirimat  seeking  a  broader  label  indication  covering  the  treatment  of
smallpox, monkeypox, cowpox, and complications from Vaccinia infection.

In  December,  2020,  the  Company  filed  an  application  for  marketing  authorization  in  Canada  for  oral  tecovirimat,  using  the  same  formulation

approved by the FDA.

Manufacturing

SIGA does not have a manufacturing infrastructure and does not intend to develop one for the manufacture of TPOXX®. SIGA relies on and uses
third parties known as Contract Manufacturing Organizations (“CMOs”) to procure commercial raw materials and supplies, and to manufacture TPOXX®.
SIGA's  CMOs  apply  methods  and  controls  in  facilities  that  are  used  for  manufacturing,  processing,  packaging,  testing,  analyzing  and  holding
pharmaceuticals  which  conform  to  current  good  manufacturing  practices  (“cGMP”),  the  standard  set  by  the  FDA  for  manufacture  and  storage  of
pharmaceuticals intended for human use.

Oral TPOXX®:

For the manufacture of oral TPOXX®, the Company uses the following CMOs: Albemarle Corporation (“Albemarle”); Powdersize, LLC

(“Powdersize”); Catalent Pharma Solutions LLC (“Catalent”); and Packaging Coordinators, LLC ("PCI").

In August 2011, SIGA entered into an agreement with Albemarle. Such agreement was amended in April 2015 and expired in April 2018. On
October 1, 2018, SIGA entered into a new agreement with Albemarle pursuant to which Albemarle manufactures, tests and supplies active pharmaceutical
ingredient (“API”) for use in TPOXX®. The agreement provides that, during the term of the new agreement, SIGA will purchase 100% of its internal and
external API requirements for TPOXX® from Albemarle until the later of (i) September 30, 2021 and (ii) such time as SIGA has purchased twelve metric
tons of API from Albemarle under the new agreement. From and after the later of: (i) September 30, 2021, or (ii) such time as SIGA has purchased twelve
metric tons of API from Albemarle, SIGA will purchase at least 70% of its internal and external API requirements for TPOXX® from Albemarle until the
end of the term of the new agreement (as described below), unless the Company receives an offer to purchase API at a price that Albemarle is unable to
match, in which event SIGA will purchase at least 30% of its internal and external API requirements for TPOXX® from Albemarle until September 30,
2023. There is no minimum amount of kilograms of API that must be used or acquired by SIGA. The following events are excluded from the “100% API”
requirement: (i) if a contract entered into by SIGA for the sale of final drug product (“FDP”) requires that the product used as the API for such FDP be
manufactured  outside  the  U.S.  and  Albemarle  is  unwilling  or  unable  to  subcontract  such  manufacture  to  a  party  or  parties  that  meet  the  terms  of  the
agreement; (ii) if a contract entered into by SIGA for the sale of FDP in an intravenous formulation requires different specifications than those provided for
under the agreement and the parties are not able to reach agreement on the necessary changes to the specifications or on pricing; or (iii) if Albemarle fails
to perform any of its obligations under the agreement and does not cure such failure within 30 days of written notice from SIGA. SIGA is required to pay
Albemarle within 45 days of its invoice date. Pricing for API is at a fixed price per kilogram, subject to adjustment for increases in raw material costs
and/or general manufacturing costs. Albemarle is required to deliver API that conforms to specifications outlined in the agreement; the Company is not
required to pay for API that does not meet specifications. The Company has 120 days to reject any shipments that do not meet such specifications or are
damaged.  In  addition  to  receiving  payments  for  API  deliveries,  Albemarle  is  also  paid  for  related  services,  such  as  stability  testing.  The  Company’s
agreement with Albemarle is currently scheduled to expire upon the earlier of: (i) September 30, 2023, or (ii) the fulfillment of delivery obligations under
the 19C BARDA Contract. Thereafter, the agreement shall renew for successive one-year renewal terms until either the Company or Albemarle provides
notice of non-renewal at least 90 days prior to the expiration date of a term.

Corporate Responsibility and Sustainability

SIGA focuses on the health security market and seeks to advance global health while promoting a sustainable environment.

SIGA  seeks  to  advance  global  public  health  through  its  development  and  commercial  activities,  which  include  (i)  delivering  medical
countermeasures  to  governments  and/or  non-governmental  organizations  ("NGOs")  so  that  governments  and/or  NGOs  can  cost-effectively  stockpile
treatments  for  potential  public  health  emergencies  and  (ii)  donating  therapies  to  NGOs  to  treat  patients  with  serious  infectious  diseases  in  developing
countries or those who are being treated on a compassionate basis and/or within clinical trials.

SIGA seeks to promote a sustainable environment by tracking the involvement of its manufacturing supply chain in initiatives and organizations
that  prioritize  a  sustainable  environment.  All  manufacturers  within  SIGA’s  supply  chain,  including  Albemarle,  Powdersize,  Catalent,  PCI,  Patheon  and
Roquette maintain corporate social responsibility and/or sustainability programs and publicly report on those programs.

SIGA also pursues such policies within its own corporate environment, although the scale is too small to report separately their impact.

Market for Biological Defense Programs

6

The  market  for  biodefense  countermeasures  reflects  continued  awareness  of  the  threat  of  global  terror  and  biowarfare  activity.  The  U.S.
Government  is  the  largest  source  of  development  and  procurement  funding  for  academic  institutions  and  biopharmaceutical  companies  conducting
biodefense research or developing vaccines, anti-infectives and immunotherapies directed at potential agents of bioterror or biowarfare. U.S. Government
spending on biodefense programs includes development funding awarded by the National Institute of Allergy and Infectious Diseases, BARDA and the
Department  of  Defense  (“DoD”),  and  procurement  of  countermeasures  by  BARDA,  the  Strategic  Stockpile  and  the  DoD.  For  the  fiscal  year  ending
September 30, 2021, the budget for the U.S. Department of Health and Human Services provides an annual appropriation of approximately $2.0 billion for
activities related to advanced development and procurement of medical countermeasures for biological and other threats to civilian populations.

In response to the COVID-19 pandemic, Congress has appropriated over $45 billion over the past year across four supplemental appropriations for
the purposes of developing necessary countermeasures and vaccines, prioritizing platform-based technologies with U.S.-based manufacturing capabilities,
the  purchase  of  vaccines,  therapeutics,  diagnostics,  necessary  medical  supplies,  as  well  as  medical  surge  capacity,  and  other  preparedness  and  response
activities. While the focus of such appropriations is to support a broad-based response to the COVID-19 pandemic, funds from these appropriations could,
depending on the COVID-19 response, be available to support biodefense activities related to the development of new medical countermeasures, building
and upgrading of facilities, improvement in surge capacity, and procurement of ancillary medical supplies.

We believe that potential markets for the sale of biodefense countermeasures in addition to the U.S. Government include:

•
•
•
•

foreign governments, including both defense and public health agencies;
NGOs and multinational companies, including transportation and security companies
healthcare providers, including hospitals and clinics; and
state and local governments, which may be interested in these products to protect, among others, emergency responders, such as police, fire
and emergency medical personnel.

At present, oral TPOXX® is not approved for sale in the U.S. beyond sales to the U.S. Government for the purpose of stockpiling and/or usage by
the  Strategic  Stockpile.  The  Company  would  need  to  meet  additional  regulatory  requirements  before  sales  could  be  made  in  the  U.S.  beyond  the  U.S
Government.

Research Agreements and Grants

The Company has an R&D program for IV TPOXX®. This program is funded by the 19C BARDA Contract and a separate development contract
with BARDA ("IV Formulation R&D Contract"). The IV Formulation R&D Contract has a period of performance that terminates in February 2024. As of
December  31,  2020,  the  IV  Formulation  R&D  Contract  provides  for  future  aggregate  research  and  development  funding  of  up  to  approximately  $2.1
million. See Note 3 to the consolidated financial statements regarding the 19C BARDA Contract.

In July 2019, the Company was awarded a multi-year research contract valued at a total of $19.5 million, with initial available funding of $12.4
million, from the DoD to support work in pursuit of a potential label expansion for oral TPOXX® that would include post-exposure prophylaxis ("PEP") of
smallpox (such work known as the "PEP Label Expansion Program" and the contract referred to as the "PEP Label Expansion R&D Contract"). In May

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
2020, the DoD increased the scope and the contract value to a total of $26 million with current available funding of $23 million. As of December 31, 2020,
the  PEP  Label  Expansion  R&D  Contract  provides  for  future  aggregate  research  and  development  funding  under  the  award,  as  modified,  of  up  to
approximately $22.4 million. The period of performance for this contract, as modified, terminates on July 31, 2025.

Contracts  and  grants  include,  among  other  things,  options  that  may  or  may  not  be  exercised  at  the  U.S.  Government’s  discretion.  Moreover,
contracts  and  grants  contain  customary  terms  and  conditions  including  the  U.S.  Government’s  right  to  terminate  or  restructure  a  contract  or  grant  for
convenience at any time. As such, we may not be eligible to receive all available funds.

General

We receive cash payments from BARDA on a monthly basis, as services are performed or goods are purchased. Amounts under contract and grant
agreements  are  not  guaranteed  and  can  be  canceled  at  any  time  for  reasons  such  as  non-performance  or  convenience  of  the  U.S.  Government  and,  if
canceled, we will not receive funds for additional work under the agreements.

Competition

The  biotechnology  and  pharmaceutical  industries  are  characterized  by  rapidly  evolving  technology  and  intense  competition.  Our  competitors
include  many  major  pharmaceutical  companies,  each  of  which  has  financial,  technical  and  marketing  resources  significantly  greater  than  ours.
Biotechnology and other pharmaceutical competitors in the biodefense space include, but are not limited to, Emergent BioSolutions Inc., Bavarian Nordic
AS,  and  Chimerix  Inc.  Academic  institutions,  governmental  agencies  and  other  public  and  private  research  organizations  are  also  conducting  research
activities and seeking patent protection and may commercialize products on their own or through joint ventures.

TPOXX®  faces  significant  competition  for  government  funding  for  both  development  and  procurement  of  medical  countermeasures  for

biological, chemical, radiological and nuclear threats, diagnostic testing systems, and other emergency preparedness countermeasures.

Our  commercial  opportunities  could  be  reduced  or  eliminated  if  our  competitors  develop  and  commercialize  products  that  are  safer,  more
effective, have fewer side effects, are more convenient or are less expensive than products that we may develop. In addition, we may not be able to compete
effectively if our product candidates do not satisfy governmental procurement requirements, particularly requirements of the U.S. Government with respect
to biodefense products.

Human Capital Resources and Research Facilities

As  of  February  16,  2021,  we  had  42 full-time  employees.  None  of  our  employees  are  covered  by  a  collective  bargaining  agreement,  and  we
consider  our  employee  relations  to  be  satisfactory.    Our  human  capital  resources  objectives  include,  as  applicable,  identifying,  recruiting,  retaining,
incentivizing and integrating our existing and new employees, advisors and consultants with the overall goal of having an employee base that embraces
teamwork and shares a focus for using each person’s individual skills, experience and expertise in order to develop and maximize the value of corporate
assets, and achieve long-term revenue and earnings growth.

Our  research  and  development  facilities  are  located  in  Corvallis,  Oregon,  where  we  lease  approximately  10,276  square  feet  under  a  lease
agreement that commenced on January 1, 2018 and which expires in December 2021. This lease has one remaining renewal option for an additional three
years.

Intellectual Property and Proprietary Rights

SIGA’s commercial success will depend in part on its ability to obtain and maintain patent and other intellectual property protection in the U.S.
and the rest of the world for its proprietary technologies, drug targets, and potential products and to preserve its trade secrets. Because of the substantial
length  of  time  and  expense  associated  with  bringing  potential  products  through  the  development  and  regulatory  clearance  processes  to  reach  the
marketplace,  the  pharmaceutical  industry  places  considerable  importance  on  obtaining  patent  and  trade  secret  protection.  The  patent  positions  of
pharmaceutical and biotechnology companies can be highly uncertain and involve complex legal and factual questions. No consistent policy regarding the
breadth of claims allowed in biotechnology patents across various jurisdictions has emerged to date. Accordingly, SIGA cannot predict the type and extent
of claims that will be allowed in pending patent applications.

SIGA also relies upon trade secret protection for its confidential and proprietary information. No assurance can be given that other companies will
not independently develop substantially equivalent proprietary information and techniques or otherwise gain access to SIGA’s trade secrets or that SIGA
can meaningfully protect its trade secrets.

SIGA exclusively owns its key patent portfolios, which relate to its leading drug product, TPOXX® (also known as ST-246, tecovirimat). As of
January 12, 2021, the TPOXX® patent portfolio has seven patent families consisting of 27 U.S. utility patents, 86 issued foreign patents, three U.S. utility
patent applications, and 30 foreign patent applications.

The principal and material issued patents covering TPOXX® are described in the table below.

^ A Patent Term Extension Application is pending for US 7737168, which would change the expiration date from May 3, 2027 to September 4, 2031. A
Patent Term Extension Application is also pending for US 8124643, which would change the expiration date from June 18, 2024 to December 13, 2027. In
the event that both US 7737168 and US 8124643 are found to be eligible for a patent term extension, SIGA would only be able to elect one of the two
patents for which the extension is sought and would elect to extend US 7737168.

*  ARIPO  has  19  member  African  States  as  follows:  Botswana,  The  Gambia,  Ghana,  Kenya,  Lesotho,  Malawi,  Mozambique,  Namibia,  Sierra  Leone,
Liberia, Rwanda, Sao Tome and Principe, Somalia, Sudan, Swaziland, Tanzania, Uganda, Zambia and Zimbabwe.

In  addition  to  the  patents  listed  in  the  above  chart,  the  principal  and  material  patent  applications  covering  TPOXX®  include  patent  filings  in
multiple  jurisdictions,  including  the  United  States,  Europe,  Asia,  Australia,  and  other  commercially  significant  markets.  We  hold  33  patent  applications
currently pending with respect to various compositions of TPOXX®, methods of manufacturing, methods of treatment, and dosage forms. Expiration dates
for pending patent applications, if granted, will fall between 2027 and 2037.

FDA  regulations  require  that  patented  drugs  be  sold  under  brand  names  that  comply  with  various  regulations.  SIGA  must  develop  and  make
efforts to protect these brand names for each of its products in order to avoid product piracy and to secure exclusive rights to these brand names. SIGA may
expend substantial funds in developing and securing rights to adequate brand names for our products. SIGA currently has proprietary trademark rights in
SIGA®, TPOXX® and other brands used by us in the United States and certain foreign countries, but we may have to develop additional trademark rights
in order to comply with regulatory requirements. SIGA may need to pursue different names and trademarks ex-U.S. in light of native language and other
jurisdictional considerations. SIGA considers securing adequate trademark rights to be important to its business.

Government Regulation

Regulatory Approval Process

Regulation by governmental authorities in the United States and other countries is a significant factor in the manufacture and marketing of any
biopharmaceutical product that we may develop. The nature and the extent to which such regulations may apply to us will vary depending on the nature of
any  particular  product.  Virtually  all  of  our  potential  pharmaceutical  products  will  require  regulatory  approval  by  governmental  agencies  prior  to  non-
governmental  commercialization.  In  particular,  human  therapeutic  products  are  subject  to  rigorous  pre-clinical  and  clinical  testing  and  other  approval
procedures  by  the  FDA  and  similar  health  authorities  in  foreign  countries.  Various  federal  statutes  and  regulations  also  govern  or  regulate  the
manufacturing,  safety,  labeling,  storage,  recordkeeping  and  marketing  of  such  products.  The  process  of  obtaining  these  approvals  and  the  subsequent
compliance with appropriate federal and foreign statutes and regulations is complex and requires expertise and the expenditure of substantial resources.

In  order  to  test  clinically,  and  to  manufacture  and  market  products  for  diagnostic  or  therapeutic  use,  a  company  must  comply  with  mandatory
procedures  and  safety  standards  established  by  the  FDA  and  comparable  agencies  in  foreign  countries.  Before  beginning  human  clinical  testing  of  a
potential new drug in the United States, a company must file an Investigational New Drug ("IND") application and receive clearance from the FDA. An
IND application is a summary of the pre-clinical studies that were conducted to characterize the drug, including toxicity and safety studies, information on
the drug’s composition and the manufacturing and quality control procedures used to produce the drug, as well as a discussion of the human clinical studies
that are being proposed to evaluate the safety and efficacy of the product.

Table of Contents

12

The pre-marketing clinical program required for approval by the FDA for a new drug typically involves a time-consuming and costly three-phase
process.  In  Phase  I,  trials  are  conducted  with  a  small  number  of  healthy  subjects  to  determine  the  early  safety  profile,  the  pattern  of  drug  distribution,
metabolism and elimination. In Phase II, trials are conducted with small groups of patients afflicted with a target disease in order to determine preliminary
efficacy, optimal dosages and expanded evidence of safety. In Phase III, large scale, multi-center comparative trials, which may include both controlled and
uncontrolled studies, are conducted with patients afflicted with a target disease in order to provide enough data for statistical proof of efficacy and safety
required by the FDA and other authorities. Additional trials may be required to evaluate how a new drug interacts with other drugs as well as if the drug has
any impact on cardio-vascular or other potential risks.

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
The  FDA  closely  monitors  the  progress  of  each  of  the  three  phases  of  clinical  testing  and  may,  in  its  discretion,  reevaluate,  alter,  suspend  or
terminate the testing based on the data that have been accumulated to that point and its assessment of the risk/benefit ratio to the patients involved in the
testing. Estimates of the total time typically required for carrying out such clinical testing vary between two and 10 years. Upon completion of such clinical
testing, a company typically submits an NDA to the FDA that summarizes the results and observations of the drug during the clinical testing. Based on its
review of the NDA, the FDA will decide whether to approve the drug and whether to impose any marketing restrictions or require additional post-approval
clinical studies. This review process can be quite lengthy, and approval for the production and marketing of a new pharmaceutical product can require a
number of years and substantial funding. There can be no assurance that any approval will be granted on a timely basis, if at all. In some circumstances, a
new formulation of an approved product may be reviewed through a supplemental NDA process which relies in part on the prior approval of the initial
formulation.

The FDA amended its regulations, effective June 30, 2002, to include the “Animal Rule” in circumstances that would permit the typical clinical
testing regime to approve certain new drug and biological products used to reduce or prevent the toxicity of chemical, biological, radiological, or nuclear
agents not otherwise naturally present for use in humans based on evidence of safety in healthy subjects and evidence of effectiveness derived only from
appropriate animal studies and any additional supporting data. The FDA has indicated that approval for therapeutic use of TPOXX® was determined under
the “Animal Rule.”

Once  the  product  is  approved  for  sale,  FDA  regulations  govern  the  manufacturing  and  marketing  activities,  and  a  post-marketing  testing  and
surveillance  program  may  be  required  to  monitor  a  product’s  usage  and  effects.  Product  approvals  may  be  withdrawn  if  compliance  with  regulatory
standards is not maintained. Many other countries in which products developed by us may be marketed impose similar regulatory processes.

FDA regulations also make available an alternative regulatory mechanism that may lead to use of the product under limited circumstances. The
Emergency Use Authorization (“EUA”) authority allows the FDA Commissioner to strengthen the public health protections against biological, chemical,
radiological and nuclear agents that may be used to attack the American people or the U.S. armed forces. Under this authority, the FDA Commissioner may
allow medical countermeasures to be used in an emergency to diagnose, treat or prevent serious or life-threatening diseases or conditions caused by such
agents when appropriate findings are made concerning the nature of the emergency, the availability of adequate and approved alternatives, and the quality
of available data concerning the drug candidate under consideration for emergency use.

Legislation and Regulation Related to Bioterrorism Counteragents and Pandemic Preparedness

Because our drug candidates are intended for the treatment of diseases that may result from acts of bioterrorism or biowarfare or for pandemic

preparedness, they may be subject to the specific legislation and regulation described below and elsewhere in this Annual Report on Form 10-K.

Project BioShield

Project  BioShield  and  related  2006  federal  legislation  provide  procedures  for  biodefense-related  procurement  and  awarding  of  research  grants,
making it easier for the U.S. Department of Health and Human Services (“HHS”) to commit funds to countermeasure projects. Project BioShield provides
alternative  procedures  under  the  Federal  Acquisition  Regulation,  the  general  rubric  for  acquisition  of  goods  and  services  by  the  U.S.  Government,  for
procuring property or services used in performing, administering or supporting biomedical countermeasure research and development. In addition, if the
Secretary of HHS deems that there is a pressing need, Project BioShield authorizes the Secretary of HHS to use an expedited award process, rather than the
normal peer review process, for grants, contracts and cooperative agreements related to biomedical countermeasure research and development activity.

Table of Contents

13

Under Project BioShield, the Secretary of HHS, with the concurrence of the Secretary of the U.S. Department of Homeland Security and upon the
approval of the President, can contract to purchase unapproved countermeasures for the Strategic Stockpile in specified circumstances. The U.S. Congress
is notified of a recommendation for a Strategic Stockpile purchase after Presidential approval. Project BioShield specifies that a company supplying the
countermeasure  to  the  Strategic  Stockpile  is  paid  on  delivery  of  a  substantial  portion  of  the  countermeasure.  To  be  eligible  for  purchase  under  these
provisions, the Secretary of HHS must determine that there are sufficient and satisfactory clinical results or research data, including data, if available, from
pre-clinical and clinical trials, to support a reasonable conclusion that the countermeasure will qualify for approval or licensing within eight years. Project
BioShield also allows the Secretary of HHS to authorize the emergency use of medical products that have not yet been approved by the FDA. To exercise
this authority, the Secretary of HHS must conclude that:

•

•

•

•

the agent for which the countermeasure is designed can cause serious or life-threatening disease;

the product may reasonably be believed to be effective in detecting, diagnosing, treating or preventing the disease;

the known and potential benefits of the product outweigh its known and potential risks; and

there is no adequate alternative to a product that is approved and available.

Although this provision permits the Secretary of HHS to circumvent FDA approval (entirely, or in part) for procurement and use, its use in this
manner  would  likely  be  limited  to  rare  circumstances.  Prior  to  the  award  of  the  BARDA  Contract  in  May  2011,  the  Secretary  of  HHS  concluded  that
TPOXX® would qualify within eight years for approval by the FDA for therapeutic use against smallpox.

Public Readiness and Emergency Preparedness Act

The Public Readiness and Emergency Preparedness Act (the "PREP Act") provides immunity for manufacturers from claims under state or federal
law for “loss” arising out of the administration or use of a “covered countermeasure” in the United States. However, injured persons may still bring a suit
for “willful misconduct” against the manufacturer under some circumstances. “Covered countermeasures” include security countermeasures and “qualified
pandemic or epidemic products,” including products intended to diagnose or treat pandemic or epidemic disease, as well as treatments intended to address
conditions caused by such products. For these immunities to apply, the Secretary of HHS must issue a declaration in cases of public health emergency or
“credible risk” of a future public health emergency. Since 2007, the Secretary of HHS has issued eight declarations under the PREP Act to protect from
liability countermeasures that are necessary to prepare the nation for potential pandemics or epidemics, including a declaration on October 10, 2008 that

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
provides  immunity  from  tort  liability  as  it  relates  to  smallpox.  The  PREP  Act  was  amended  in  2015  to  extend  protection  for  smallpox  and  other
countermeasures from December 31, 2015 to December 31, 2022.

Foreign Regulation

As noted above, in addition to regulations in the United States, we might be subject to a variety of foreign regulations governing clinical trials and
commercial sales and distribution of our drug candidates. Regardless of any FDA approval of a product, we may have to obtain approval of that product by
the comparable regulatory authorities of foreign countries before we can commence clinical trials or marketing of the product in those countries. The actual
time required to obtain clearance to market a product in a particular foreign jurisdiction varies substantially, based upon the type, complexity and novelty of
the pharmaceutical drug candidate, the specific requirements of that jurisdiction, and in some countries whether the FDA has previously approved the drug
for marketing. The requirements governing the conduct of clinical trials, marketing authorization, pricing and reimbursement vary from country to country.
Certain foreign jurisdictions, including the European Union and Canada, have adopted certain biodefense-specific regulations akin to that available in the
United States such as a procedure similar to the “Animal Rule” promulgated by the FDA for review and potential approval of biodefense products.

Regulations Regarding Government Contracting

The status of an organization as a government contractor in the United States and elsewhere means that the organization is also subject to various
statutes and regulations, including the Federal Acquisition Regulation, which governs the procurement of goods and services by agencies of the United
States. These governing statutes and regulations can impose stricter penalties than those normally applicable to commercial contracts, such as criminal and
civil  damages  liability  and  suspension  and  debarment  from  future  government  contracting.  In  addition,  pursuant  to  various  statutes  and  regulations,
government  contracts  can  be  subject  to  unilateral  termination  or  modification  by  the  government  for  convenience  in  the  United  States  and  elsewhere,
detailed auditing requirements, statutorily controlled pricing, sourcing and subcontracting restrictions and statutorily mandated processes for adjudicating
contract disputes.

Item 1A. Risk Factors

This report contains forward-looking statements and other prospective information relating to future events. These forward-looking statements and other
information are subject to risks and uncertainties that could cause our actual results to differ materially from our historical results or currently anticipated
results including the following:

Risks Related to Our Dependence on Government Contracts

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
Government contracts require ongoing funding decisions by governments. A substantial percentage of potential contract revenues would come from the
19C BARDA Contract, and the majority of the potential revenue under the 19C BARDA Contract is tied to options which may or may not be exercised
at the sole discretion of BARDA. Reduced or discontinued BARDA funding, or the non-exercise of contract options under the 19C BARDA Contract,
could cause our business, financial condition, results of operations and prospects to suffer materially.

Government-funded contracts typically consist of a base period of performance and options for the performance of certain future activities. The
value of goods and services subject to options may constitute the majority of the total value of the underlying contract, as in the case of the 19C BARDA
Contract.

The  funding  of  government  programs,  which  fund  BARDA’s  purchases  under  the  19C  BARDA  Contract,  is  subject  to  Congressional
appropriations,  generally  made  on  a  fiscal  year  basis  even  though  a  program  may  continue  for  several  years.  Our  government  customers  are  subject  to
political  considerations  and  budgetary  constraints,  which  result  in  uncertainties  as  to  continued  funding  of  their  ongoing  programs,  including  SIGA’s
contracts.

More than 90% of remaining contract value of the 19C BARDA Contract is tied to options exercisable in the sole discretion of BARDA. There is
no  guarantee  that  any  of  the  remaining  options  will  be  exercised,  or  if  they  are  exercised  when  such  exercise  of  options  will  occur.  If  some  of  these
options are not exercised, because levels of government expenditures and authorizations for biodefense decrease or shift to other programs, or for any other
reason, our business, financial condition, results of operations and prospects may suffer materially.

Government procurement contracts are mostly set at fixed prices determined at inception of the contract based on estimates of the time, resources and
expenses required to perform these contracts. If our estimates are not accurate, we may not be able to earn an adequate return or may incur a loss
under these arrangements.

Remaining unexercised options under current government procurement contracts, including the 19C BARDA Contract, are predominately fixed-
price.  We  expect  that  our  future  contracts  with  the  U.S.  Government  and  foreign  governments  for  TPOXX®  as  well  as  contracts  for  other  biodefense
product candidates would also be fixed-price arrangements. Under a fixed-price contract, we are required to deliver our products at a fixed price determined
at the inception of the contract regardless of the actual costs we incur, and to absorb any costs incurred in satisfaction of our obligations. Our failure to
anticipate technical problems, estimate costs accurately or control costs during performance of a fixed-price contract could reduce the profitability of such
contract or cause a loss, which could in turn negatively affect our operating results.

We expect future operating revenues to come significantly from contracts with BARDA for the provision and maintenance of the U.S. Government’s
stockpile  of  TPOXX®.  If  BARDA  does  not  enter  into  additional  contracts  after  the  19C  BARDA  Contract  to  maintain  or  expand  the  stockpile  of
TPOXX®, our long-term business, financial condition and operating results could be materially harmed.

The  success  of  our  business  and  our  operating  results  for  the  foreseeable  future  will  be  substantially  dependent  on  the  U.S.  Government’s
commitment to maintaining or expanding its stockpile of TPOXX®. Failure to secure and perform additional contracts after the 19C BARDA Contract to
substantially maintain or expand the stockpile of TPOXX® could have a material adverse effect on our long-term business, financial condition, results of
operations  and  prospects.  Additionally,  the  19C  BARDA  Contract  does  not  necessarily  increase  the  likelihood  that  we  will  secure  future  comparable
contracts with the U.S. Government.

Laws and regulations affecting government contracts and grants might make it more costly and difficult for us to successfully conduct our business.

Our  business  with  the  U.S.  Federal  Government,  and  any  future  business  with  state  and  local  governmental  agencies  are  subject  to  specific
procurement regulations and a variety of other legal and compliance obligations. These laws and rules include those related to procurement integrity, rates
and  pricing  of  services  and  goods  to  be  reimbursed  by  the  U.S.  Government,  export  control,  government  security  regulations,  employment  practices,
protection of the environment, accuracy of records and the recording and reporting of costs, and foreign corrupt practices.  Among the most significant
government contracting regulations that affect our business are:

•

the Federal Acquisition Regulation and other agency-specific regulations supplemental to the Federal Acquisition Regulation, which
comprehensively regulate the procurement, formation, administration and performance of government contracts;  

Table of Contents

16

•

•

•

the business ethics and public integrity obligations, which govern conflicts of interest and the hiring of former government employees, restrict the
granting of gratuities and funding of lobbying activities and incorporate other requirements such as the Anti-Kickback Act and the Foreign
Corrupt Practices Act;  

export and import control laws and regulations; and  

laws, regulations and executive orders restricting the use and dissemination of information classified for national security purposes and the
exportation of certain products and technical data.

Compliance with these obligations increases our performance and compliance costs. Failure to comply with these regulations and requirements
could lead to suspension or debarment, for cause, from government contracting or subcontracting for a period of time. The termination of a government
contract as a result of our failure to satisfy any of these obligations would have a material negative impact on our operations and harm our reputation and
ability to procure other government contracts or grants in the future.

Unfavorable provisions in government contracts and grants, some of which may be customary, may harm our future business, financial condition and
potential operating results.

Government contracts and grants customarily contain provisions that give the government substantial rights and remedies, many of which are not

typically found in commercial contracts, including (but not limited to) provisions that allow the government to:

•

terminate existing contracts or grants, in whole or in part, for any reason or no reason;

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
•

•

•

•

•

•

•

•

•

unilaterally reduce or modify grants, contracts or subcontracts, including through the use of equitable price adjustments;

cancel multi-year contracts or grants and related orders if funds for performance for any subsequent year become unavailable;

decline to exercise an option to renew, or to exercise the maximum amount specified in, a contract or grant;

exercise an option to purchase only the minimum amount specified in a contract or grant;

claim rights to products or assets, including intellectual property, developed under a contract or grant;

take actions that result in a longer development timeline or higher costs than expected;

suspend or debar a contractor from doing business with the government or a specific government agency due to regulatory or compliance failures;

pursue criminal or civil remedies under the False Claims Act and the False Statements Accountability Act; and

control or prohibit the export of products.

Generally,  government  contracts  contain  provisions  permitting  unilateral  termination  or  modification,  in  whole  or  in  part,  at  the  government’s
convenience.  Under  general  principles  of  government  contracting  law,  if  the  government  terminates  a  contract  or  grant  for  convenience,  the  terminated
company may recover only its incurred or committed costs, settlement expenses and profit on work completed prior to the termination. If the government
terminates a contract or grant for default, the defaulting company is entitled to recover costs incurred and associated profits on accepted items only and may
be liable for excess costs incurred by the government in procuring undelivered items from another source. Our government contracts and grants, including
the 19C BARDA Contract, could be terminated under these circumstances.

A U.S. Government shutdown could negatively impact our business and liquidity

17

Each  year,  the  U.S.  Congress  must  pass  all  spending  bills  in  the  federal  budget.  If  any  such  spending  bill  is  not  timely  passed,  a  government
shutdown may close many federally run operations, and halt work for federal employees unless they are considered essential or such work is separately
funded by a continuing resolution or by industry. If a government shutdown were to occur, we could experience a delay in contract funding decisions by the
government. Additionally, we could be materially harmed by any prolonged government shutdown.

Our business could be adversely affected by a negative audit by the U.S. Government.

U.S. Government agencies such as the Defense Contract Audit Agency (the “DCAA”), routinely audit and investigate government contractors.
These  agencies  review  a  contractor’s  performance  under  its  contracts  and  grants,  cost  structure,  and  compliance  with  applicable  laws,  regulations  and
standards.

The DCAA also reviews the adequacy of, and a contractor’s compliance with, its internal control systems and policies, including the contractor’s
purchasing, property, estimating, compensation and management information systems. Any cost found to be improperly allocated to a specific contract will
not be reimbursed, and such costs already reimbursed must be refunded. If an audit uncovers improper or illegal activities, we may be subject to civil and
criminal  penalties  and  administrative  sanctions,  including  termination  of  contracts,  forfeiture  of  profits,  suspension  of  payments,  fines  and  suspension,
debarment or prohibition from doing business with the U.S. Government.  Such actions would also negatively affect our reputation.

Risks Related to Regulatory Approvals

If we are not able to obtain regulatory approvals for certain additional indications or formulations of TPOXX® from the FDA, we may not be able to
realize the full benefits of any BARDA contracts and may not be able to commercialize such formulations or indications other than through existing
sales to BARDA, and our ability to generate future revenue could be materially impaired.

The  development  and  full  commercialization  of  additional  indications  or  formulations  of  TPOXX®  in  the  U.S.,  such  as  the  intravenous
formulation  or  indication  of  use  for  post-exposure  prophylaxis,  including  the  testing,  manufacture,  safety,  efficacy,  recordkeeping,  labeling,  storage,
approval, advertising, promotion, sale and distribution, are subject to comprehensive regulation by the FDA and other regulatory agencies in the United
States and by comparable authorities in other countries and jurisdictions. We could fail to achieve FDA or other regulatory approval of certain indications
or  formulations  of  TPOXX®,  or  there  could  be  delays  in  such  approval  of  TPOXX®,  or  the  approved  labeling  for  such  indications  or  formulations  of
TPOXX® may differ from expectations. Failure to obtain regulatory approval of certain indications or formulations for TPOXX® may prevent us from
fully commercializing TPOXX® in the United States other than through existing sales to BARDA and may impact other regulatory authorities' review of
TPOXX®,  which  in  turn,  could  adversely  impact  commercializing  TPOXX®  in  other  countries,  and  such  delays  or  required  alterations  to  regulatory
applications could also have a material adverse effect on the Company.

Failure to obtain regulatory approval in international jurisdictions could prevent us from marketing our products abroad.

To  market  our  products  in  Canada,  the  European  Union  and  certain  other  foreign  jurisdictions,  we  may  need  to  obtain  separate  regulatory
approvals  and  comply  with  numerous  and  varying  regulatory  requirements.  The  approval  procedure  varies  among  countries  and  can  involve  additional
testing  and  differing  manufacturing  or  labeling  requirements.  Complying  with  such  requirements  may  take  additional  time  prior  to  approval  and  delay
commercial activities in those jurisdictions.

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
The  foreign  regulatory  approval  process  may  include  all  of  the  risks  associated  with  obtaining  FDA  approval  for  expanded  indications  or  new
formulations of TPOXX®. We may not obtain foreign regulatory approvals on a timely basis, if at all. Regulatory approval by the FDA, which we obtained
for oral TPOXX®, or by a foreign regulatory authority such as Canada or the European Medicines Agency (EMA) does not ensure approval by regulatory
authorities in other foreign countries or jurisdictions or by the FDA for expanded indications or new formulations. In addition, failure to obtain approval in
one  jurisdiction  may  impact  our  ability  to  obtain  approvals  elsewhere.  We  may  not  be  able  to  file  for  or  receive  necessary  regulatory  approvals  to
commercialize our products in any non-U.S. market, in which case, our target market may be reduced and our ability to realize the full market potential of
our product candidates may be harmed and our business, financial condition, results of operations and prospects may be adversely affected.

Risks Related to Commercial Activities

We cannot predict whether or when we will be permitted to commercialize TPOXX® other than the oral formulation for smallpox treatment.

We have only received FDA approval for the oral formulation of TPOXX®, not the intravenous or liquid suspension/pediatric formulation, or any
other indication beyond treatment for smallpox, for TPOXX®. Because pharmaceutical manufacturers are only permitted to commercialize indications and
formulations that have received FDA approval (or in other jurisdictions according to their applicable regulatory and legal frameworks), any regulatory or
legal setbacks as described above could have an adverse impact on the Company’s ability to sell other formulations or for other uses of TPOXX® pending
such approvals.

Changing  political  or  social  factors  and  opposition,  including  protests  and  potential  related  litigation,  may  delay  or  impair  our  ability  to  market
TPOXX® and any other biodefense product candidates and may require us to spend time and money to address these issues.

Products developed to treat diseases caused by or to combat the threat of bioterrorism or biowarfare will be subject to changing political and social
environments. The political and social responses to bioterrorism and biowarfare have been unpredictable and much debated. Changes in the perception of
the risk that military personnel or civilians could be exposed to biological agents as weapons of bioterrorism or biowarfare may delay or cause resistance to
bringing investigational products to market or limit pricing or purchases of approved products, any of which could materially harm our business.

Lawsuits, publicity campaigns or other negative publicity may adversely affect the degree of market acceptance of, and thereby limit the demand
for, TPOXX® and our biodefense product candidates. In such event, our ability to market and sell such products may be hindered, the commercial success
of TPOXX® and other products we develop may be harmed and we may need to expend time, attention and resources addressing such legal or publicity
issues, thereby reducing our revenues and having a material adverse impact on us.

Our ability to grow our business may depend in part on our ability to achieve sales of TPOXX® to customers other than the U.S. government.

An  element  of  our  business  strategy  is  to  sell  TPOXX®  internationally  to  foreign  governments,  as  well  as  to  customers  other  than  the  U.S.
Government.  These  potential  non-U.S.  Government  customers  include  foreign  governments,  as  well  as  state  and  local  governments,  non-governmental
organizations focused on global health like the World Health Organization, health care institutions like hospitals (domestic and foreign) and certain large
business organizations interested in protecting their employees against global threats and protecting first responders in cases of emergencies.

To the extent we seek such non-government sales in the U.S., we may need to meet additional regulatory requirements.

The market for sales of TPOXX® to U.S. customers other than the U.S. Government is undeveloped, and we may not be successful in generating

meaningful sales of TPOXX®, if any, to these potential customers.

If we fail to increase our sales of TPOXX® to customers other than the U.S. Government, our business and opportunities for growth could be

limited.

We  expect  our  future  international  revenues  to  depend  heavily  on  the  success  of  the  efforts  of  Meridian  pursuant  to  an  International  Promotion
Agreement, which may not be successful. 

Pursuant  to  the  International  Promotion  Agreement  described  under  “Business,"  we  granted  a  third  party,  Meridian  Medical  Technologies,  a
division  of  Pfizer,  exclusive  rights  to  market,  advertise,  promote,  offer  for  sale,  or  sell  oral  TPOXX®  in  all  geographic  regions  except  for  the  United
States (the “Territory”), and Meridian agreed not to commercialize any competing product, as defined in the International Promotion Agreement, in the
specified field of use in the Territory.  Our future international revenues will likely depend heavily on the success of the efforts of Meridian pursuant to the
International Promotion Agreement, which may not be successful.

If  we  are  unable  to  expand  our  internal  sales  and  marketing  capabilities  or  enter  into  agreements  with  third  parties  with  expertise  in  sales  and
marketing, we may be unable to expand our sales of TPOXX® or other product candidates in the U.S., including to  U.S. customers other than the U.S.
Government.

In the United States market, we have retained all sales and marketing rights with respect to oral TPOXX®. In this market, we currently employ a
small, targeted group to support development and business activities related to TPOXX®. We plan to continue our current approach for sales to the U.S.
Government of any other biodefense product candidates that we may successfully develop. This approach may prove insufficient to adequately support our
development and business activities in the United States.

In order to expand our sales of TPOXX® or other product candidates in the U.S., including to U.S. customers other than the U.S. Government, we
may  need  to  enhance  our  own  sales  and  marketing  capabilities,  and/or  enter  into  collaborations  with  third  parties  able  to  perform  these  services  or
outsource these functions to third parties.  There is no assurance that we will be able to do so successfully, and even if we are able to do so that it will have
a significant impact on our growth or profitability.

Although TPOXX® is currently stockpiled only by the U.S. and Canadian governments and not sold commercially, in the future we may be required to
perform additional clinical trials or change the labeling of TPOXX® if we or others identify side effects after we are on the market, which could harm

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
future sales of such product.

If we or others identify side effects of any approved product, or if manufacturing problems occur:

•

•

•

regulatory approval may be withdrawn;

reformulation of our products, additional clinical trials or other testing or changes in labeling of our products may be required;

changes to or re-approvals of manufacturing facilities used by SIGA may be required;

20

Table of Contents

•

•

•

sales of the affected products may drop significantly;

our reputation in the marketplace may suffer; and

lawsuits, including class action suits, may be brought against us.

Any  of  the  above  occurrences  could  harm  or  prevent  future  sales  of  the  affected  product  or  could  increase  the  costs  and  expenses  of

commercializing and marketing these products.

If we obtain the necessary marketing approval to sell TPOXX® to non-government customers and are able to charge higher prices than we do to the
U.S. Government, healthcare reform and controls on healthcare spending may nonetheless limit the price we charge for our products and the amounts
that we can sell.

There have been a number of legislative and regulatory proposals in the United States to change the health care system in ways that could affect
pricing if we seek to sell TPOXX® to non-government customers. One enacted proposal, the Patient Protection and Affordable Care Act, as amended by
the  Health  Care  and  Education  Reconciliation  Act  of  2010  (collectively,  the  “Healthcare  Reform  Act”),  substantially  changed  the  way  healthcare  is
financed  by  both  governmental  and  private  insurers  and  had  a  substantial  effect  on  the  pharmaceutical  industry.  The  Healthcare  Reform  Act  contains  a
number  of  provisions,  including  those  governing  enrollment  in  federal  healthcare  programs  like  Medicare,  reimbursement  changes  and  rules  protecting
against  fraud  and  abuse  that  will  affect  existing  healthcare  programs.  If  we  obtain  marketing  approval  for  sale  of  TPOXX®  beyond  the  U.S.
government customers and are able to charge higher prices than we do to the U.S. Government, healthcare reform and controls on healthcare spending may
nonetheless limit the price we charge for our products and the amounts that we can sell. For example, it is possible that some of our revenue may be derived
from governmental healthcare programs, including Medicare. Furthermore, beginning in 2011, the Healthcare Reform Act imposed a non-deductible excise
tax on pharmaceutical manufacturers or importers who sell “branded prescription drugs,” which includes innovator drugs and biologics (excluding orphan
drugs or generics) to U.S. Government programs. The Healthcare Reform Act and other healthcare reform measures that may be adopted in the future could
have an adverse effect on our industry generally and potential future sales and profitability of our current or future products specifically.

Laws  and  regulations  governing  international  operations  may  hinder  us  from  developing,  manufacturing  and  selling  certain  product  candidates
outside of the United States and require us to revise and implement costly compliance programs.

As we expand our operations outside of the United States, we must comply with numerous laws and regulations relating to business operations in
each jurisdiction in which we plan to operate. The creation and implementation of international business practices and compliance programs may be time-
consuming and costly, and such programs can be challenging to oversee and to enforce, particularly where reliance on third parties is required.

The Foreign Corrupt Practices Act, or FCPA, prohibits any U.S. individual or business from paying, offering, or authorizing payment or offering
anything of value, directly or indirectly, to any foreign official, political party or candidate for the purpose of influencing any act or decision of the foreign
entity in order to assist the individual or business in obtaining or retaining business. The FCPA also obligates companies whose securities are listed in the
United  States  to  comply  with  certain  accounting  provisions  requiring  the  Company  to  maintain  books  and  records  that  accurately  and  fairly  reflect  all
transactions  of  the  corporation,  including  international  subsidiaries,  and  to  devise  and  maintain  an  adequate  system  of  internal  accounting  controls  for
international operations. 

As we expand our operations outside of the U.S., compliance with the FCPA, U.K. Bribery Act and similar anti-corruption provisions in other
jurisdictions may be expensive and can be difficult, particularly in countries in which corruption is a recognized problem. Certain payments to hospitals in
connection with clinical studies and other work have been deemed to be improper payments to government officials and have led to FCPA enforcement
actions. In addition, biodefense companies like SIGA often sell their products directly to foreign governments.

Various laws, regulations and executive orders also restrict the use and dissemination outside of the United States, or the sharing with certain non-
U.S.  nationals,  of  information  classified  for  national  security  purposes,  as  well  as  certain  products  and  technical  data  relating  to  those  products.  As  we
expand our presence outside of the United States, we may require additional resources to ensure compliance with these laws.

The failure to comply with laws governing international business practices may result in substantial penalties, including suspension or debarment
from  government  contracting.  Violation  of  the  FCPA  can  result  in  significant  civil  and  criminal  penalties  that  can  be  levied  on  the  Company  and  its
executives.

Indictment  alone  under  the  FCPA  can  lead  to  suspension  of  the  right  to  do  business  with  the  U.S.  Government  until  the  pending  claims  are
resolved.  Conviction  of  a  violation  of  the  FCPA  can  result  in  long-term  disqualification  as  a  government  contractor.  The  termination  of  a  government
contract  or  relationship  as  a  result  of  our  failure  to  satisfy  any  of  our  obligations  under  laws  governing  international  business  practices  could  have  a
material negative impact on our operations and harm our reputation and ability to procure government contracts. The SEC also may suspend or bar issuers
from trading securities on United States exchanges for violations of the FCPA’s accounting provisions.

Other  countries  such  as  the  UK  have  anti-bribery  laws  similar  to  or  more  expansive  in  scope  than  the  FCPA  which  may  be  applicable  to  our

operations as we expand outside the U.S.

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
In  connection  with  our  International  Promotion  Agreement  with  Meridian,  Meridian  will  serve  as  the  entity  that  markets  and  promotes  oral
TPOXX®  (except  in  the  United  States)  and  will  be  the  counterparty  to  any  agreements  with  covered  foreign  jurisdictions.  As  such,  Meridian  will  be
responsible for anti-corruption compliance related to its activities.

We could incur net losses in the future if options are not exercised under the 19C BARDA Contract.

21

While our current cash position is strong, our ability to continue to fund future operations will be substantially impacted by cash flows from the
19C BARDA Contract, which may not be sufficient if BARDA elects, in its sole discretion, not to exercise or to significantly delay exercise of some or all
of the remaining options under the 19C BARDA Contract. If cash flows from the 19C BARDA Contract are significantly different from expectations, or if
operating  expenses  or  other  expenses  meaningfully  exceed  our  expectations  or  cannot  be  adjusted  accordingly,  then  our  business,  financial  condition,
results of operations and prospects could be materially adversely affected.

Risks Related to Manufacturing, Storage and Our Dependence on Third Parties

If  third  parties  on  whom  we  rely  for  manufacturing  and  raw  materials  of  TPOXX®,  and  managing  our  inventory,  do  not  perform  as  contractually
required or as we expect, we may not be able to successfully satisfy our obligations under the 19C BARDA Contract and our business would suffer.

We currently rely on third-party manufacturers and service providers to provide raw materials and manufacture, package, test and ship TPOXX®.
Under the 19C BARDA Contract, we are responsible for the performance of these third-party contractors, and our contracts with these third parties give us
certain supervisory and quality control rights, but we do not exercise day-to-day control over their activities.

Additionally, we may rely on a third-party provider, or multiple providers, to store or transport a portion of the stockpile of IV TPOXX® under the

19C BARDA Contract, entrusting such vendor or vendors with the care and handling of a substantial portion of IV TPOXX® inventory.

If a third-party provider fails to comply with applicable laws and regulations, fails to meet expected deadlines, fails to conduct trials in accordance
with  regulatory  requirements  or  our  stated  protocols,  experiences  shortages  or  delays,  or  otherwise  does  not  carry  out  its  contractual  duties  to  us,  or
encounters physical damage or natural disaster or disruptions at its facilities, for example as a result of the novel coronavirus COVID-19 pandemic, our
ability  to  meet  our  obligations  under  the  19C  BARDA  Contract  or  to  develop,  obtain  approval  and  commercialization  of  IV  TPOXX®  or  other  drug
candidates, could be significantly impaired or delayed. We do not currently have the internal capacity to perform these important functions, and we may not
be able to maintain commercial arrangements for these services on reasonable terms.

If third parties do not manufacture our drug candidates or products in sufficient quantities and at an acceptable cost or in compliance with regulatory
or contractual requirements and specifications, the fulfillment of contractual requirements under the 19C BARDA Contract, or any other procurement
contract, or the development of our drug candidates could be delayed, prevented or impaired.

If our contract manufacturers are unable to generate enough materials to meet commercial obligations or satisfy clinical needs, for example as a
result  of  disruption  resulting  from  the  novel  coronavirus  COVID-19  pandemic,  the  success  of  drug  products  may  be  jeopardized.  Our  current  and
anticipated  future  dependence  upon  others  for  the  manufacture  of  our  drug  candidates  may  adversely  affect  our  ability  to  develop  drug  candidates  and
perform on commercial contracts on a timely and competitive basis. If our third-party manufacturers’ production processes malfunction or contaminate our
drug supplies during manufacturing, we may incur significant inventory loss that may not be covered by our contractual provisions or insurance policies.

We currently rely on third parties to demonstrate regulatory compliance, for regulatory and science support and for quality assurance with respect
to the drug candidates manufactured for us. We intend to continue to rely on these third parties for these purposes with respect to production of commercial
supplies of drugs that we successfully develop. Manufacturers are subject to ongoing, periodic, unannounced inspection by the FDA and corresponding
state and foreign agencies or their designees to ensure strict compliance with applicable laws and regulations.

We  cannot  be  certain  that  our  present  or  future  manufacturers  will  be  able  to  comply  with  these  regulations  and  other  FDA  regulatory
requirements or similar regulatory requirements outside the U.S. In addition, due to the novel coronavirus COVID-19 pandemic, regulatory authorities may
not  conduct  required  inspections  at  our  CMO  facilities,  and  without  such  inspections,  drug  approvals  could  be  delayed.  Our  government  contracts  and
grants call for compliance with all applicable legal and regulatory requirements, however, we do not control third-party manufacturers and their methods
for ensuring adherence to regulatory and legal standards. If we or these third parties fail to comply with applicable regulations, sanctions could be imposed
on us which could significantly delay and adversely affect supplies of our drug candidates.

Problems related to large-scale commercial manufacturing could cause an increase in costs or shortages of products or a delay in product launches.

Manufacturing  API  and  finished  drug  products,  especially  in  large  quantities,  is  complex.  Our  products  require  several  manufacturing  steps  at
multiple  facilities,  and  may  involve  complex  techniques  to  assure  quality  and  sufficient  quantity,  especially  as  the  manufacturing  scale  increases.  Our
products must be made consistently and in compliance with a clearly defined manufacturing process. Accordingly, it is essential to be able to validate and
control the manufacturing process to assure that it is reproducible. Slight deviations anywhere in the manufacturing process, including obtaining materials,
filling, labeling, packaging, storage, shipping, quality control and testing, some of which all pharmaceutical companies, including SIGA, experience from
time to time, may result in lot failures, delay in the release of lots, product recalls or spoilage. Success rates can vary dramatically at different stages of the
manufacturing process, which can lower yields and increase costs. We may experience deviations in the manufacturing process that may take significant
time and resources to resolve and, if unresolved, may affect manufacturing output and/or cause us to fail to satisfy contractual commitments, lead to delays
in  our  clinical  trials  or  result  in  litigation  or  regulatory  action.  Such  actions  would  hinder  our  ability  to  meet  contractual  obligations  and  could  cause
material adverse consequences for our business.

Growth  of  our  business  may  be  impacted  significantly  by  our  success  in  completing  development  and  commercialization  of  drug  candidates,  new
formulations  or  additional  indications  for  TPOXX®.  If  we  are  unable  to  commercialize  new  drug  candidates,  new  formulations,  or  additional
indications, or experience significant delays in doing so, our business may be materially harmed.

We have invested a substantial amount of our efforts and financial resources in the development of our drug candidates. Our ability to generate
near-term cash flows is primarily dependent on the success of our smallpox antiviral drug TPOXX®, which has only been approved by the FDA in oral
form. The commercial success of our current and future drug candidates, new formulations or additional indications for TPOXX®, will depend on many
factors, including:

•

•

•

•

•

•

•

successful development, formulation and cGMP scale-up of drug manufacturing that meets FDA requirements;

successful development of animal models;

successful completion of non-clinical development, including studies in approved animal models;

our ability to pay the expense of filing, prosecuting, defending and enforcing patent claims and other intellectual property rights;

successful completion of clinical trials;

receipt of marketing approvals from FDA for IV and liquid suspension/pediatric formulations of TPOXX® and similar foreign regulatory
authorities;

establishing arrangements on reasonable terms with suppliers and contract manufacturers;

• manufacturing stable commercial supplies of drug candidates, including availability of raw materials;

•

•

launching commercial sales of the product, whether alone or in collaboration with others; and

acceptance  of  the  product  by  potential  government  customers,  public  health  experts,  physicians,  patients,  healthcare  payors  and  others  in  the
medical community.

We may rely on FDA regulations known as the “Animal Rule” to obtain approval for most of our biodefense drug candidates. The Animal Rule
permits the use of animal efficacy studies together with human clinical safety trials to support an application for marketing approval. These regulations are
relied  upon  only  occasionally.  It  is  possible  that  results  from  these  animal  efficacy  studies  may  not  be  predictive  of  the  actual  efficacy  of  our  drug
candidates in humans. If we are not successful in completing the development and commercialization of our drug candidates, whether due to our efforts or
due to concerns raised by our governmental regulators or customers, our business could be materially adversely affected.

Table of Contents

23

We  may  not  be  able  to  fully  commercialize  the  IV  and  liquid  suspension/pediatric  formulation  of  TPOXX®,  or  other  additional  indications  for
TPOXX®, if our clinical trials do not demonstrate adequate safety or our animal studies do not demonstrate adequate efficacy.

Before obtaining regulatory approval for the sale of our drug candidates, extensive development is required. The goal of development is to use
clinical studies to demonstrate the safety of our drug candidates and animal trials to demonstrate the efficacy of our drug candidates. Clinical trials and
animal  studies,  and  related  work,  are  resource-intensive,  difficult  to  design  and  implement,  can  take  many  years  to  complete  and  are  uncertain  as  to
outcome. Success in pre-clinical testing and early clinical trials does not ensure that later clinical trials or animal efficacy studies will be successful, and
interim results of a clinical trial or animal efficacy study do not necessarily predict final results.

A failure of one or more of our clinical trials or animal efficacy studies can occur at any stage of development. We may experience numerous
unforeseen events during, or as a result of, pre-clinical testing and the clinical trial or animal efficacy study process that could delay or prevent our ability
to receive regulatory approval or commercialize our drug candidates, including:

•

•

•

•

•

•

•

•

•

regulators or institutional review boards may not authorize us to commence a clinical trial or conduct a clinical trial at a prospective trial site;

we may decide, or regulators may require us, to conduct additional pre-clinical testing or clinical trials, or we may abandon projects that we expect
to be promising, if our pre-clinical tests, clinical trials or animal efficacy studies produce negative or inconclusive results;

we might have to suspend or terminate our clinical trials if the participants are being exposed to unacceptable health risks;

regulators  or  institutional  review  boards  may  require  that  we  hold,  suspend  or  terminate  clinical  development  for  various  reasons,  including
noncompliance with regulatory requirements;

the resources required to manage and oversee our clinical trials could escalate and become cost prohibitive;

our governmental regulators may impose requirements on clinical trials, pre-clinical trials or animal efficacy studies that we cannot meet or that
may prohibit or limit our ability to perform or complete the necessary testing in order to obtain regulatory approval;

any regulatory approval we ultimately obtain may be limited or subject to restrictions or post-approval commitments that render the product not
commercially viable;

we may not be successful in recruiting a sufficient number of qualifying subjects for our clinical trials; or

the effects of our drug candidates may not be the desired effects or may include undesirable side effects or the drug candidates may have other
unexpected characteristics; or

the required resources, regulations, or challenges associated with animal studies may increase and make our studies more difficult.

IV  and  Liquid  Suspension/Pediatric  TPOXX®  formulations  are  currently  in  product  development  and  there  can  be  no  assurance  of  successful
development or ultimate commercialization beyond the 19C BARDA Contract.

The fact that the FDA has approved the oral formulation of TPOXX® does not guarantee that our approach to drug development will be effective
or  will  result  in  the  successful  commercialization  of  the  IV  or  liquid  suspension/pediatric  formulation  of  TPOXX®,  any  new  indication  such  as  post-
exposure prophylaxis, of TPOXX® or any other drug. We cannot predict with certainty whether any other drug candidate or expanded indication resulting
from our research and development efforts will be approved by the FDA.

All of our potential drug candidates are prone to the risks of failure inherent in pharmaceutical product development, including the possibility that

our drug candidates will not or cannot:

•

•

•

•

•

•

•

•

be shown to be safe, non-toxic and effective;

otherwise meet applicable regulatory standards;

receive the necessary regulatory approvals;

develop into commercially viable drugs;

be manufactured or produced economically and on a large scale;

be successfully marketed;

be paid for by governmental procurers or be reimbursed by governmental or private insurers; or

achieve customer acceptance.

In addition, third parties may seek to preclude us from marketing our drugs through enforcement of their proprietary or intellectual property rights that we
are not aware of, or third parties may succeed in marketing equivalent or superior drug products that do not infringe our intellectual property. Our failure to
develop safe, commercially viable future drug candidates or obtain approval for expanded indications and formulations of TPOXX® could have a material
adverse effect on our ability to grow our business, and impair our financial condition and operations.

Risks Related to Our Intellectual Property

24

Our ability to compete may decrease if we do not adequately protect our intellectual property rights.

Our  commercial  success  will  depend  in  part  on  our  ability  to  obtain  and  maintain  regulatory  exclusivity,  patent  and  other  intellectual  property
protection  for  our  proprietary  technologies,  drug  targets  and  potential  products  and  to  preserve  our  trade  secrets  and  trademark  rights.  Because  of  the
substantial length of time and expense associated with bringing potential products through the development and regulatory clearance processes to reach the
marketplace, the pharmaceutical industry places considerable importance on obtaining regulatory, patent and trade secret protection. The patent positions of
pharmaceutical and biotechnology companies can be highly uncertain and involve complex legal and factual questions. No consistent policy regarding the
breadth of claims allowed in biotechnology patents worldwide has emerged to date. Accordingly, we cannot definitively predict the type and breadth of
claims allowed in patents covering our products.

SIGA exclusively owns its key patent portfolios, which relate to its leading drug product, TPOXX® (also known as ST-246, tecovirimat). As of
January 12, 2021, the TPOXX® patent portfolio has seven patent families consisting of 27 U.S. utility patents, 86 issued foreign patents, three U.S. utility
patent applications, and 30 foreign patent applications.

With  FDA  regulatory  approval  of  oral  TPOXX®  in  July  2018,  we  were  awarded  seven  years  of  regulatory  exclusivity  by  the  U.S.  Patent  and
Trademark Office based on orphan drug designation for the product. Such protection is separate from, and in addition to, our patent and other intellectual
property rights and provides for exclusivity to July 2025.

We  also  rely  on  trade  secrets,  know-how,  continuing  technological  innovation  and  licensing  opportunities.  In  an  effort  to  maintain  the
confidentiality  and  ownership  of  trade  secrets  and  proprietary  information,  we  require  our  employees,  consultants  and  some  collaborators  to  execute
confidentiality  and  invention  assignment  agreements  upon  commencement  of  a  relationship  with  us.  These  agreements  may  not  provide  meaningful
protection for our trade secrets, confidential information or inventions in the event of unauthorized use or disclosure of such information, and adequate
remedies may not exist in the event of such unauthorized use or disclosure.

If our technologies are alleged or found to infringe the patents or proprietary rights of others, we may be sued, we may have to pay damages or be
barred from pursuing a technology, or we may have to license those rights and pay royalties to or from others on unfavorable terms. If we are sued,
even if we prevail, such litigation may be costly.

Our commercial success will depend significantly on our ability to operate without infringing the patents or proprietary rights of third parties. Our
technologies, or the technologies of third parties on which we may depend, may infringe the patents or proprietary rights of others. If there is an adverse
outcome in any dispute concerning rights to these technologies, then we could be subject to significant liability, required to license disputed rights from or
to other parties and/or required to cease using a technology necessary to carry out our research, development and commercialization activities. We do not
currently license any patent rights from third parties relative to TPOXX®.

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
If our patents are challenged and found to be invalid or unenforceable, the value of our products could be harmed, and we could be subject to

competition earlier than we anticipated.

The costs to establish or defend against claims of infringement or interference with patents or other proprietary rights can be expensive, distracting
and  time-consuming,  even  if  the  outcome  is  favorable.  An  outcome  of  any  patent  or  proprietary  rights  administrative  proceeding  or  litigation  that  is
unfavorable to us may cause us to incur significant costs, and have a material adverse effect on us. Additionally, we may not prevail in any such action and
such litigation often takes years to resolve creating business uncertainty if we are not able to resolve it quickly.

Furthermore, like many biopharmaceutical companies, we may from time to time hire scientific personnel formerly employed by other companies
involved in one or more areas similar to the activities conducted by us. It is possible that we and/or these individuals may be subject to allegations of trade
secret misappropriation or other similar claims as a result of their prior affiliations.

Risks Related to Our Common Stock

Concentration of ownership of our capital stock could delay or prevent a change of control.

Our  directors,  executive  officers  and  principal  stockholders  beneficially  own  a  significant  percentage  of  our  common  stock.  As  a  result,  these
stockholders,  if  acting  together,  have  the  ability  to  influence  the  outcome  of  corporate  actions  requiring  stockholder  approval.  Additionally,  this
concentration  of  ownership  may  have  the  effect  of  delaying  or  preventing  a  change  of  control  of  SIGA.  As  of  February  24,  2020,  directors,  executive
officers  and  principal  stockholders  (excluding  index  funds)  beneficially  owned  approximately  42%  of  our  outstanding  common  stock.  In  addition  to
owning common stock of the Company, directors and certain executive officers have the right to acquire additional stock through the exercise or conversion
of certain securities.

Our stock repurchase program could affect the price of our common stock and increase volatility and may be suspended or terminated at any time,
which may result in a decrease in the trading price of our common stock.

On March 5, 2020 our Board of Directors authorized a share repurchase program for up to $50 million of our common stock through December
31, 2021. This stock repurchase program does not obligate the Company to repurchase any dollar amount or number of shares of our common stock and
may be suspended or discontinued at any time, which could cause the market price of our common stock to decline. Repurchases pursuant to our stock
repurchase program could affect the price of our common stock and increase its volatility. Important factors that could cause us to limit, suspend or delay
the Company’s stock repurchases, without prior notice, and that could in any event impact management’s exercise of its discretion as to the amount and
timing of such repurchases include exercise of procurement options under government contracts, alternative opportunities for strategic uses of cash, the
stock  price  of  the  Company’s  common  stock,  market  conditions,  and  other  corporate  liquidity  requirements  and  priorities.  The  existence  of  our  stock
repurchase program could cause the price of our common stock to be higher than it would be in the absence of such a program and could potentially reduce
the market liquidity for our common stock. Additionally, repurchases under our stock repurchase program would diminish our cash reserves, which could
impact our ability to pursue other opportunities, further develop our technology or adversely affect our operating results. There can be no assurance that any
stock repurchases would enhance stockholder value because the market price of our common stock may decline below the levels at which we repurchased
such shares. Any failure to repurchase shares could negatively impact our reputation and investor confidence in us and our stock price.

A future issuance of preferred stock may adversely affect the rights of the holders of our common stock.

Our certificate of incorporation allows our Board of Directors to issue up to 20,000,000 shares of preferred stock and to fix the voting powers,
designations, preferences, rights and qualifications, limitations or restrictions of these shares without any further vote or action by the stockholders. The
rights of the holders of common stock will be subject to, and could be adversely affected by, the rights of the holders of any preferred stock that we may
issue in the future. The issuance of preferred stock could have the effect of making it more difficult for a third party to acquire a majority of our outstanding
voting stock, thereby delaying, deferring or preventing a change of control.

General

Global  infectious  disease  outbreaks,  such  as  the  COVID-19  pandemic,  or  climate-related  matters  could  negatively  impact  the  global  economy  on  a
broad scale and our business in particular.

Occurrence  of  a  global  infectious  disease  outbreak,  such  as  the  novel  coronavirus  (COVID-19)  that  escalated  into  a  worldwide  pandemic,  or
climate-related disasters, could have a broad impact on global economic conditions, sourcing of raw materials and may continue to impact our ability to
promote our products successfully to international governments who may need to divert resources to address the ongoing pandemic and other such matters.
Such delays may reduce our expected revenue from international sales to foreign governments and thereby adversely impact our projected business growth.

The  COVID-19  pandemic,  for  example,  has  caused  significant  societal  and  economic  disruption.  Such  disruption,  and  the  associated  risks  and
costs, are expected to continue for an indeterminate period of time. Given the uncertain future course of the COVID-19 pandemic, and the uncertain scale
and scope of its future impact, the Company is continually reviewing business and financial risks related to the pandemic and seeking coordination with its
government partners with respect to the performance of current and future government contracts. Additionally, the Company is continually coordinating
with service providers and vendors, in particular Contract Manufacturing Organizations ("CMOs") that constitute our supply chain, to review actions and
risks caused by the COVID-19 pandemic.

As of the filing date of this document, the Company has not identified or been notified by government customers of impediments to the continued
full performance of their government contracts. Additionally, the Company’s supply chain for the manufacture of TPOXX® has remained operational on
current  projects  without  material  COVID-19  related  disruption,  and  in  the  ordinary  course  of  operations,  the  supply  chain  has  secured  sufficient  raw
materials to support manufacture and product delivery activities on current projects. With regard to day-to-day operations, the COVID-19 pandemic has at
times  slowed  the  daily  pace  of  execution  of  government  contracts  as  well  as  new  contract  generation,  as  U.S.  and  foreign  government  staff  overseeing
health security preparedness has been involved directly or indirectly in governmental responses to the pandemic, which has diverted government staff time
that  would  normally  be  directed  toward  contract  matters  involving  SIGA.  The  Company  expects  to  experience  delays,  or  slower-than-usual  pace,  in
connection  with  certain  research  and  development  activities,  such  as  those  that  involve  clinical  trials.  The  Company  does  not  currently  expect  any

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
pandemic-related delays in research and development activities to have a material adverse impact on the financial condition or annual financial results of
the Company, or its long-term performance, but there can be no assurance that such delays will not have such a material adverse impact in the future.

While to date the COVID-19 pandemic has not adversely affected the liquidity position of the Company, and is not currently expected to have a
material  adverse  effect  on  the  financial  condition  of  the  Company,  there  can  be  no  assurance  that  it  will  not  have  such  adverse  effects,  which  may  be
material, in the future.  Given that the pandemic has diverted foreign government staff time normally directed toward contract matters involving SIGA, the
COVID-19 pandemic could affect the timing of international contract awards for oral TPOXX, which could potentially have a material adverse effect on
the  short-term  financial  results  of  the  Company.  The  pandemic  has  resulted  in  almost  all  of  our  employees  working  from  home;  however,  the  shift  in
location for employees has not had a material adverse impact on the day-to-day operations of the Company. If the general negative effect of the COVID-19
pandemic becomes more acute or is prolonged, there could be potentially be a material adverse impact on our business and cash flows.

Future  acquisitions,  strategic  investments,  partnerships  or  alliances  could  be  difficult  to  identify  and  integrate,  divert  the  attention  of  management,
disrupt  our  business,  dilute  stockholder  value,  materially  change  the  risk  profile  of  the  Company  and/or  adversely  affect  our  operating  results  and
financial condition.

We may in the future seek to acquire or invest in businesses, products or technologies that we believe could complement or expand our services,
enhance our technical capabilities or otherwise offer growth opportunities. The pursuit of potential acquisitions may divert the attention of management and
cause  us  to  incur  various  expenses  in  identifying,  investigating  and  pursuing  businesses.  In  addition,  we  may  not  be  able  to  find  and  identify  desirable
acquisition  targets  or  be  successful  in  entering  into  an  agreement  with  any  particular  target  or  consummating  any  such  agreement.  Even  if  we  do
consummate an acquisition, in connection therewith we may be required to issue equity (thereby diluting our current stockholders) or debt, we may not be
able to integrate successfully the acquired personnel, operations and technologies, or effectively manage the combined business following the acquisition,
or  the  acquired  business  could  otherwise  fail  to  meet  our  expectations,  which,  in  each  case,  could  have  a  material  adverse  effect  on  our  business
projections, financial condition, results of operations and prospects.

The health security market in which we compete and will compete is highly competitive.

26

The health security industry is characterized by rapid and significant technological change. Our success will depend on our ability to develop and
apply  our  technologies  in  the  design  and  development  of  our  product  candidates  and  to  establish  and  maintain  a  market  for  our  product  candidates.  In
addition, there are many companies, both public and private, including major pharmaceutical and chemical companies, specialized biotechnology firms,
universities and other research institutions engaged in developing pharmaceutical, health security and biotechnology products. Many of these companies
have substantially greater financial, technical, research and development resources, and human resources than us. Competitors may develop products or
other technologies that are more effective than any that are being developed by us or may obtain FDA approval for products more rapidly than us. If we
commence commercial sales of products, we still must compete in the manufacturing and marketing of such products, areas in which it is very difficult to
succeed and in which we have limited experience and in which we are partially dependent on third parties. Many potential competitors have manufacturing
facilities and established marketing capabilities that may enable such companies to market competing products through existing channels of distribution
which could provide a substantial advantage.

Product liability lawsuits could cause us to incur liabilities, which could be substantial, and require us to limit commercialization of any products that
we may develop.

Like all pharmaceutical companies, we face an inherent business risk related to the sale of TPOXX® and any other products that we successfully
develop  and  the  testing  of  our  product  candidates  in  clinical  trials.  TPOXX®  is  currently  identified  as  a  covered  countermeasure  under  the  PREP  Act
declaration issued in October 2008, as amended, which provides us with substantial immunity with respect to the manufacture, administration or use of
TPOXX®. Under our BARDA Contracts, the U.S. Government should indemnify us against claims by third parties for death, personal injury and other
damages  related  to  TPOXX®,  including  reasonable  litigation  and  settlement  costs,  to  the  extent  that  the  claim  or  loss  results  from  specified  risks  not
covered by insurance or caused by our grossly negligent or criminal behavior. The collection process under the PREP Act can be lengthy and complicated,
and there is no guarantee that we would be able to recover these amounts from the U.S. Government.

If we cannot successfully defend ourselves against future claims that our product or product candidates caused injuries and we are not entitled to
or able to obtain indemnity by the U.S. Government with respect to such claims, or if the U.S. Government does not honor its indemnification obligations,
we may incur liabilities, which could be substantial. Regardless of merit or eventual outcome, product liability claims may result in decreased demand for
any  product  candidate  or  product  that  we  may  develop;  withdrawal  of  a  product  from  the  market;  costs  and  management  time  and  focus  to  defend  the
related litigation; substantial monetary awards to trial participants or patients; loss of revenue; harm to our reputation; the inability to commercialize any
products that we may develop. Additionally, a successful product liability claim or series of claims brought against us could cause our stock price to fall,
could decrease our financial resources and materially exhaust our existing insurance or limit our ability to obtain insurance going forward, all of which
would materially adversely affect our business and financial position.

We currently have product liability insurance with coverage up to a $10 million annual aggregate limit and a $10 million per occurrence limit.
Product liability insurance is difficult to obtain and increasingly expensive. Should we face claims, we may not be able to maintain insurance coverage at a
reasonable cost and we may not be able to maintain or obtain insurance coverage that will be adequate to satisfy any liability that may arise.

Our activities may involve hazardous materials, use of which may subject us to environmental regulatory liabilities.

Our  biopharmaceutical  research  and  development  sometimes  may  involve  the  use  of  hazardous  and  radioactive  materials  and  generation  of
biological waste. We are subject to federal, state and local laws and regulations governing the use, manufacture, storage, handling and disposal of these
materials  and  certain  waste  products,  and  may  have  to  incur  significant  costs  to  comply  with  current  or  future  environmental  laws  and  regulations.
Although we believe that our CMOs’ safety procedures for handling and disposing of these materials comply with legally prescribed standards, the risk of
accidental contamination or injury from these materials cannot be completely eliminated. In the event of an accident, we could be held liable for damages,
and  this  liability  could  exceed  our  resources.  We  use  through  third  parties,  for  example,  small  amounts  of  radioactive  isotopes  commonly  used  in
pharmaceutical  research,  which  are  stored,  used  and  disposed  of  in  accordance  with  Nuclear  Regulatory  Commission  regulations.  Our  general  liability
policy provides coverage up to annual aggregate limits of $2 million and coverage of $2 million per occurrence.

 
 
 
 
 
 
 
 
 
 
 
 
 
The loss of key personnel or our ability to recruit or retain qualified personnel could adversely affect our results of operations.

We rely upon the ability, expertise, judgment, discretion, integrity and good faith of our senior management team, including our Chief Executive
Officer,  Chief  Scientific  Officer  and  other  key  executives.  Our  success  is  dependent  upon  our  personnel  and  our  ability  to  recruit,  retain  and  train  high
quality  employees.  We  must  continue  to  recruit,  retain  and  motivate  management  and  other  employees  sufficient  to  maintain  our  current  business  and
support our projected growth. The loss of services of any members of our key management team could have a material adverse effect on our business.

Our business and operations would suffer in the event of computer system failures, cyber-attacks or a deficiency in our cyber-security.

Despite the implementation of security measures, our internal computer systems, and those of third parties on which we rely, are vulnerable to
damage from computer viruses, malware, natural disasters, terrorism, war, telecommunication and electrical failures, cyber-attacks or cyber-intrusions over
the Internet, attachments to emails, persons inside our organization or persons with access to systems inside our organization. The risk of a security breach
or disruption, particularly through cyber-attacks or cyber-intrusion, including by computer hackers, foreign governments and cyber terrorists, has generally
increased  as  the  number,  intensity  and  sophistication  of  attempted  attacks  and  intrusions  from  around  the  world  have  increased  and  been  targeted  at
pharmaceutical companies in particular. If such an event were to occur and cause interruptions in our operations, it could result in a material disruption of
our drug development programs. For example, the loss of clinical trial data from completed or ongoing or planned clinical trials could result in delays in
our regulatory approval efforts and significantly increase our costs to recover or reproduce the data. Also, confidential patient and other information may be
compromised in a cyber-attack or cyber-intrusion. To the extent that any disruption or security breach was to result in a loss of or damage to our data or
applications,  or  inappropriate  disclosure  of  confidential  or  proprietary  information,  we  could  incur  material  legal  claims  and  liability,  damage  to  our
reputation, and the further development of our drug candidates could be delayed.

We may need additional funding, which may not be available to us, and which may force us to delay, reduce or limit proposed acquisitions or strategic
investments or any of our non-government funded product development programs or commercial efforts.

Although our current cash position is strong, we may require additional financing and, while we have raised funds through credit facilities and the
issuance of new equity or the exercise of options or warrants in the past, there is no guarantee that we will continue to be successful in raising such funds
should we need to seek to do so. If we are unable to raise additional funds, we could be forced to discontinue, cease or limit certain strategic transactions or
operations  and  equity  investors  could  experience  significant  or  total  losses  of  their  investments.  Our  cash  flows  may  fall  short  of  our  projections  or  be
delayed,  or  our  expenses  may  increase,  which  could  result  in  our  capital  being  consumed  significantly  faster  than  anticipated.  If  we  are  able  to  obtain
additional financing through the sale of equity or convertible debt securities, such sales may contain terms, such as liquidation and other preferences that
are  not  favorable  to  us  or  our  stockholders.  If  we  raise  additional  funds  through  collaboration  and  licensing  arrangements  with  third  parties,  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. Debt financing
arrangements, if available, may require us to pledge certain assets or enter into covenants that could restrict our business activities or our ability to incur
further indebtedness and may be at interest rates and contain other terms that are not favorable to our stockholders.

Item 1B. Unresolved Staff Comments

None.

Item 2. Properties

Our headquarters are located in New York, NY and our research and development facilities are located in Corvallis, Oregon. In May 2017, we

entered into a new 10-year lease with a related party to let 3,200 square feet in New York, NY to serve as our corporate headquarters.

In Corvallis, we lease approximately 10,276 square feet. Until its expiration on December 31, 2017, this facility was leased under an amended
lease agreement signed in January 2007, and most recently changed through an addendum in April 2015. On November 3, 2017 we entered into a new lease
for the same space which was scheduled to expire in December 2019. In the second quarter of 2019, we exercised the first renewal option which expires in
December 2021. This lease has one remaining renewal option for three years.

Item 3. Legal Proceedings

From  time  to  time,  we  may  be  involved  in  a  variety  of  claims,  suits,  investigations  and  proceedings  arising  from  the  ordinary  course  of  our
business, collections claims, breach of contract claims, labor and employment claims, tax and other matters. Although such claims, suits, investigations and
proceedings are inherently uncertain and their results cannot be predicted with certainty, we believe that the resolution of such current pending matters, if
any, will not have a material adverse effect on our business, consolidated financial position, results of operations or cash flow. Regardless of the outcome,
litigation can have an adverse impact on us because of legal costs, diversion of management resources and other factors.

On March 5, 2020, the Company announced that the Board of Directors had authorized a share repurchase program under which the Company
may repurchase, from time to time, up to an aggregate of $50 million of the Company’s common stock through December 31, 2021. The timing and actual
number  of  shares  repurchased  will  depend  on  a  variety  of  factors,  including:  exercise  of  procurement  options  under  government  contracts;  alternative
opportunities for strategic uses of cash; the stock price of the Company’s common stock; market conditions; and other corporate liquidity requirements and
priorities. Prior to executing any repurchases under this program, the Company’s Term Loan needed to be fully repaid or its terms needed to be amended to
allow for share repurchases.

Unregistered Sale of Equity Securities and Use of Proceeds

On  November  19,  2020,  the  Company  issued  393,646  shares  of  its  common  stock  to  an  investor  on  a  net  basis  upon  the  partial  exercise  of  a
warrant to purchase common stock of the Company. To exercise the warrant, the investor surrendered to the Company 106,354 shares of common stock
otherwise issuable under the warrant in order to effect the partial warrant exercise. The exercise price of the warrant was $1.50 per share. Such shares were
issued pursuant to the exemption from the registration requirements of the Securities Act provided by Section 4(2) of the Securities Act and/or Regulation
D  promulgated  thereunder,  and  the  issuance  did  not  involve  any  underwriters,  underwriting  discounts  or  commissions,  or  any  public  offering.  The
purchaser is an accredited investor, and the Company issued the shares without any general solicitation or advertisement.

following discussion and other parts of this Annual Report contain forward-looking information that involves risks and uncertainties.

Overview

We  are  a  commercial-stage  pharmaceutical  company.  Our  lead  product,  TPOXX®  (“oral  TPOXX®”),  is  an  FDA-approved  oral

formulation antiviral drug for the treatment of human smallpox disease caused by variola virus.

On July 13, 2018 the United States Food & Drug Administration (“FDA”) approved oral TPOXX® for the treatment of smallpox. Oral TPOXX®
is a novel small-molecule drug that has been delivered to the U.S. Strategic National Stockpile (“Strategic Stockpile”) under the Project BioShield Act of
2004 (“Project BioShield”). Concurrent with the approval, the FDA granted the Company's request for a Priority Review Voucher (“PRV”). A PRV is a
voucher  that  may  be  used  to  obtain  an  accelerated  FDA  review  of  a  product  candidate.  On  October  31,  2018,  the  Company  sold  its  PRV  for  cash
consideration of $80.0 million.

COVID-19 Pandemic

The  COVID-19  pandemic  has  caused  significant  societal  and  economic  disruption.  Such  disruption,  and  the  associated  risks  and  costs,  are
expected to continue for an indeterminate period of time. Given the uncertain future course of the COVID-19 pandemic, and the uncertain scale and scope
of  its  future  impact,  the  Company  is  continually  reviewing  business  and  financial  risks  related  to  the  pandemic  and  seeking  coordination  with  its
government partners with respect to the performance of current and future government contracts. Additionally, the Company is continually coordinating
with service providers and vendors, in particular Contract Manufacturing Organizations ("CMOs") that constitute our supply chain, to review actions and
risks caused by the COVID-19 pandemic.

As of the filing date of this document, the Company has not identified or been notified by government customers of impediments to the continued
full performance of their government contracts. Additionally, the Company’s supply chain for the manufacture of TPOXX® has remained operational on
current  projects  without  material  COVID-19  related  disruption,  and  in  the  ordinary  course  of  operations,  the  supply  chain  has  secured  sufficient  raw
materials to support manufacture and product delivery activities on current projects. With regard to day-to-day operations, the COVID-19 pandemic has at
times  slowed  the  daily  pace  of  execution  of  government  contracts  as  well  as  new  contract  generation,  as  U.S.  and  foreign  government  staff  overseeing
health security preparedness has been involved directly or indirectly in governmental responses to the pandemic, which has diverted government staff time
that  would  normally  be  directed  toward  contract  matters  involving  SIGA.  The  Company  expects  to  experience  delays,  or  slower-than-usual  pace,  in
connection  with  certain  research  and  development  activities,  such  as  those  that  involve  clinical  trials.  The  Company  does  not  currently  expect  any

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
pandemic-related delays in research and development activities to have a material adverse impact on the financial condition or annual financial results of
the Company, or its long-term performance, but cannot give assurances as to the full extent of the impact at this time.

Overall, the COVID-19 pandemic has not adversely affected the liquidity position of the Company, nor is it currently expected to have a material
adverse effect on the financial condition of the Company.  Given that the pandemic has diverted foreign government staff time normally directed toward
contract  matters  involving  SIGA,  the  COVID-19  pandemic  could  affect  the  timing  of  international  contract  awards  for  oral  TPOXX®;  otherwise,  the
pandemic is not currently expected to have a material adverse effect on the 2021 financial results of the Company. The pandemic has resulted in almost all
of our employees working from home; however, the shift in location for employees has not had a material adverse impact on the day-to-day operations of
the Company. If the general negative effect of the COVID-19 pandemic becomes more acute or is prolonged, there could be potential risks to our business
and cash flows.

Lead Product-TPOXX®

19C BARDA Contract

On  September  10,  2018,  the  Company  entered  into  a  contract  with  the  U.S.  Biomedical  Advanced  Research  and  Development  Authority
("BARDA")  pursuant  to  which  SIGA  agreed  to  deliver  up  to  1,488,000  courses  of  oral  TPOXX®  to  the  U.S.  Strategic  National  Stockpile  ("Strategic
Stockpile"), and to manufacture and deliver to the Strategic Stockpile, or store as vendor-managed inventory, up to 212,000 courses of the intravenous (IV)
formulation of TPOXX® (“IV TPOXX®”). Additionally, the contract includes funding from BARDA for advanced development of IV TPOXX®, post-
marketing activities for oral and IV TPOXX®, and procurement activities. As of December 31, 2020, the contract with BARDA (as amended, modified, or
supplemented  from  time  to  time,  the  "19C  BARDA  Contract")  contemplates  up  to  approximately  $602.5  million  of  payments,  of  which  approximately
$51.7  million  of  payments  are  included  within  the  base  period  of  performance  of  five  years,  approximately  $127.1  million  of  payments  are  related  to
exercised  options  and  up  to  approximately  $423.7  million  of  payments  are  currently  specified  as  unexercised  options.  BARDA  may  choose  in  its  sole
discretion when, or whether, to exercise any of the unexercised options. The period of performance for options is up to ten years from the date of entry into
the 19C BARDA Contract and such options could be exercised at any time during the contract term, including during the base period of performance. 

The  base  period  of  performance  specifies  potential  payments  of  approximately  $51.7  million  for  the  following  activities:  payments  of
approximately $11.1 million for the delivery of approximately 35,700 courses of oral TPOXX® to the Strategic Stockpile; payments of $8.0 million for the
manufacture of 20,000 courses of final drug product of IV TPOXX® ("IV FDP"), of which $3.2 million of payments are related to the manufacture of bulk
drug  substance  ("IV  BDS")  to  be  used  in  the  manufacture  of  IV  FDP;  payments  of  approximately  $32.0  million  to  fund  advanced  development  of  IV
TPOXX®; and payments of approximately $0.6 million for supportive procurement activities. As of December 31, 2020, the Company had received or
billed  for  $11.1  million  for  the  successful  delivery  of  approximately  35,700  courses  of  oral  TPOXX®  to  the  Strategic  Stockpile,  $3.2  million  for  the
manufacture of IV BDS and $9.7 million for other base period activities. IV BDS is expected to be used for the manufacture of 20,000 courses of IV FDP.
The $3.2 million received for the manufacture of IV BDS has been recorded as deferred revenue as of December 31, 2020 and December 31, 2019; such
amount is expected to be recognized as revenue when IV TPOXX® containing such IV BDS is delivered to the Strategic Stockpile or placed in vendor-
managed inventory.

The  options  that  have  been  exercised  to  date  provide  for  payments  up  to  approximately  $127.1  million.  There  are  exercised  options  for  the
following activities: payments up to $11.2 million for the procurement of raw materials to be used in the manufacture of at least 363,070 courses of oral
TPOXX®, payments up to $101.3 million for the delivery of up to 363,070 courses of oral TPOXX®; and, payments of up to $14.6 million for funding of
post-marketing activities for oral TPOXX®. As of December 31, 2020, the Company has received the following payments in connection with exercised
options: $11.2 million was received for the procurement of raw materials and such amount was initially recorded as deferred revenue and was recognized
as revenue during the year ended December 31, 2020, with deliveries of approximately 363,000 courses, in the aggregate, of oral TPOXX®; $101.3 million
was received in connection with the June, September and October deliveries, in total, of approximately 363,000 courses of oral TPOXX®; and $5.4 million
has been received or billed for in connection with post-marketing activities for oral TPOXX®.

Unexercised options specify potential payments up to approximately $423.7 million in total (if all such options are exercised). There are options
for the following activities: payments of up to $337.7 million for the delivery of up to approximately 1,089,000 courses of oral TPOXX® to the Strategic
Stockpile; payments of up to $76.8 million for the manufacture of up to 192,000 courses of IV FDP, of which up to $30.7 million of payments would be
paid upon the manufacture of IV BDS to be used in the manufacture of IV FDP; payments of up to approximately $3.6 million to fund post-marketing
activities for IV TPOXX®; and payments of up to approximately $5.6 million for supportive procurement activities.

The options related to IV TPOXX® are divided into two primary manufacturing steps. There are options related to the manufacture of bulk drug
substance (“IV BDS Options”), and there are corresponding options (for the same number of IV courses) for the manufacture of final drug product (“IV
FDP Options”). BARDA may choose to exercise any, all, or none of these options in its sole discretion. The 19C BARDA Contract includes: three separate
IV  BDS  Options,  each  providing  for  the  bulk  drug  substance  equivalent  of  64,000  courses  of  IV  TPOXX®;  and  three  separate  IV  FDP  Options,  each
providing  for  64,000  courses  of  final  drug  product  of  IV  TPOXX®.  BARDA  has  the  sole  discretion  as  to  whether  to  simultaneously  exercise  IV  BDS
Options and IV FDP Options, or whether to exercise options at different points in time (or alternatively, to only exercise the IV BDS Option but not the IV
FDP  Option).  If  BARDA  decides  to  only  exercise  IV  BDS  Options,  then  the  Company  would  receive  payments  up  to  $30.7  million;  alternatively,  if
BARDA decides to exercise both IV BDS Options and IV FDP Options, then the Company would receive payments up to $76.8 million. For each set of
options relating to a specific group of courses (for instance, the IV BDS and IV FDP options that reference the same 64,000 courses), BARDA has the
option to independently purchase IV BDS or IV FDP. The Company estimates that sales of the IV formulation under this contract (under current terms),
assuming the IV FDP Options were exercised, would have a gross margin (sales less cost of sales, as a percentage of sales) that is less than 40%.

Under the terms of this contract, exercise of procurement options are at the sole discretion of BARDA. The request for proposal that preceded the
award of the 19C BARDA Contract indicated that the expected purpose of the contract was to maintain the level of smallpox antiviral preparedness in the
Strategic  Stockpile.  Based  on  prior  product  delivery  activity,  and  current  FDA-approved  shelf  life  of  oral  TPOXX®,  the  Company  estimates  that
approximately one million courses of smallpox antiviral treatment would need to be delivered to the U.S. Government between 2021 and 2023 in order to
maintain stockpile levels of unexpired smallpox antiviral treatment during this period.     

2011 BARDA Contract

 
 
 
 
 
 
 
 
 
 
 
 
On May 13, 2011, the Company signed a contract with BARDA pursuant to which BARDA agreed to buy from the Company 1.7 million courses

of oral TPOXX®. Additionally, the Company agreed to contribute to BARDA 300,000 courses at no additional cost to BARDA.

The contract with BARDA (as amended, modified, or supplemented from time to time the "2011 BARDA Contract”) includes a base contract, as
modified,  (“2011  Base  Contract”)  as  well  as  options.  The  2011  Base  Contract  specifies  approximately  $508.4  million  of  payments  (including  exercised
options), of which, as of December 31, 2020, $459.8 million has been received by the Company for the manufacture and delivery of 1.7 million courses of
oral TPOXX® and $45.6 million has been received for certain reimbursements in connection with development and supportive activities. Approximately
$3.0 million remains eligible to be received in the future for reimbursements of development and supportive activities.

For courses of oral TPOXX® that have been physically delivered to the Strategic Stockpile under the 2011 BARDA Contract, there are product
replacement  obligations,  including:  (i)  a  product  replacement  obligation  in  the  event  that  the  final  version  of  oral  TPOXX®  approved  by  the  FDA  was
different  from  any  courses  of  oral  TPOXX®  that  had  been  delivered  to  the  Strategic  Stockpile  (the  "FDA  Approval  Replacement  Obligation");  (ii)  a
product  replacement  obligation,  at  no  cost  to  BARDA,  in  the  event  that  oral  TPOXX®  is  recalled  or  deemed  to  be  recalled  for  any  reason;  and  (iii)  a
product  replacement  obligation  in  the  event  that  oral  TPOXX®  does  not  meet  any  specified  label  claims.  On  July  13,  2018,  the  FDA  approved  oral
TPOXX®  for  the  treatment  of  smallpox  and  there  is  no  difference  between  the  approved  product  and  courses  in  the  Strategic  Stockpile.  As  such,  the
possibility of the FDA Approval Replacement Obligation resulting in any future replacements of product within the Strategic Stockpile is remote.

The  2011  BARDA  Contract  includes  options.  On  July  30,  2018,  the  2011  BARDA  Contract  was  modified  and  BARDA  exercised  its  option
relating to FDA approval of the aforementioned 84-month expiry for oral TPOXX® for which the Company was paid $50.0 million in August 2018. With
the  option  exercise,  the  2011  BARDA  Contract  was  modified  so  that  the  2011  Base  Contract  increased  by  $50.0  million.  Remaining  options,  if  all
were  exercised  by  BARDA,  would  result  in  aggregate  payments  to  the  Company  of  $72.7  million,  including  up  to  $58.3  million  of  funding  for
development and supportive activities such as work on a post-exposure prophylaxis ("PEP") indication for TPOXX® and/or $14.4 million of funding for
production-related activities related to warm base manufacturing. BARDA may choose, in its sole discretion not to exercise any or all of the unexercised
options. In 2015, BARDA exercised two options related to extending the indication of the drug to the geriatric and pediatric populations. The stated value
of those exercises was immaterial.

The 2011 BARDA Contract expires in December 2024.

International Procurement Contracts

Contract with Public Health Agency of Canada

On January 13, 2021, the Public Health Agency of Canada ("PHAC") awarded a contract to Meridian Medical Technologies, Inc. (“Meridian," a Pfizer
Company) (the “Contract”) for the purchase of up to approximately $33 million of oral TPOXX® (tecovirimat) within five years. The Contract specifies
firm  commitments  for  the  purchase  of  approximately  $3.4  million  of  oral  TPOXX®  to  occur  by  March  31,  2021  and  a  cumulative  purchase  of
approximately $17 million of oral TPOXX® by March 31, 2023; the remaining courses under the Contract are targeted for delivery after March 31, 2023
and are subject to option exercise by PHAC. To date, SIGA has not finalized any deliveries yet in connection with this contract. The contract award was
coordinated  between  SIGA  and  Meridian  under  an  international  promotion  agreement,  as  amended  (the  "International  Promotion  Agreement")  that  was
entered into by the parties on June 3, 2019. As such, Meridian is the PHAC's counterparty under the Contract, and SIGA is responsible for manufacture and
delivery of any oral TPOXX® purchased thereunder. 

Canadian Military Contract

On April 3, 2020, the Company announced that the Canadian Department of National Defence (“CDND”) awarded a contract (the "Canadian Military
Contract")  to  Meridian,  pursuant  to  which  the  CDND  will  purchase  up  to  approximately  $14  million  of  oral  TPOXX®  over  four  years.    In  the  second
quarter 2020, CDND purchased $2.3 million of oral TPOXX®.  The remaining purchases are at the option of the CDND, and are expected to occur after
regulatory approval of oral TPOXX® in Canada. Meridian is the CDND's counterparty under the Canadian Military Contract, and SIGA is responsible for
manufacture and delivery of any oral TPOXX® purchased thereunder. 

International Promotion Agreement

Under the terms of the International Promotion Agreement, Meridian was granted exclusive rights to market, advertise, promote, offer for sale, or sell
oral TPOXX® in a field of use specified in the International Promotion Agreement in all geographic regions except for the United States (the “Territory”),
and Meridian has agreed not to commercialize any competing product, as defined in the International Promotion Agreement, in the specified field of use in
the Territory. SIGA will retain ownership, intellectual property, distribution and supply rights and regulatory responsibilities in connection with TPOXX®,
and, in the United States market, will also retain sales and marketing rights with respect to oral TPOXX®. SIGA’s consent shall be required for the entry
into any sales arrangement pursuant to the International Promotion Agreement.

The fee Meridian retains pursuant to the International Promotion Agreement will be a specified percentage of the collected proceeds of sales of oral
TPOXX® net of certain expenses, for years in which customer invoiced amounts net of such expenses are less than or equal to a specified threshold, and a
higher  specified  percentage  of  such  collected  net  proceeds  for  years  in  which  such  net  invoiced  amounts  exceed  the  specified  threshold.    Taking  into
account Meridian’s fee and manufacturing costs of oral TPOXX®, it is currently estimated by the Company that international sales of oral TPOXX® will
have a contribution margin (as expressed as a percentage of product sales, and before any consideration of expenses not directly related to manufacturing or
Meridian activities) of between approximately 65% and 80%.

Critical Accounting Estimates

The  methods,  estimates  and  judgments  we  use  in  applying  our  accounting  policies  have  a  significant  impact  on  the  results  we  report  in  our
consolidated financial statements, which we discuss under the heading “Results of Operations” following this section of our Management’s Discussion and
Analysis of Financial Condition and Results of Operations. Some of our accounting policies require us to make difficult and subjective judgments, often as
a result of the need to make estimates of matters that are inherently uncertain. Our most critical accounting estimates include revenue recognition over time,
the valuation of warrants granted or issued by us, and income taxes (including realization of deferred tax assets).

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
Revenue Recognition

All of our revenue is derived from long-term contracts that can span multiple years. We account for revenue in accordance with ASC Topic 606,
Revenue  from  Contracts  with  Customers  (“ASC  606”).  The  unit  of  account  in  ASC  606  is  a  performance  obligation. A  contract’s  transaction  price  is
allocated  to  each  distinct  performance  obligation  and  recognized  as  revenue  when,  or  as,  the  performance  obligation  is  satisfied.  Our  performance
obligations are satisfied over time as work progresses or at a point in time. Revenue connected with performance obligations related to product delivery and
supportive services are recognized at a point in time. Revenue connected with performance obligations related to research and development are recognized
over time.

Revenue connected with the performance obligations related to the delivery of oral TPOXX® to the Strategic Stockpile ("Delivery Performance
Obligation") under the 2011 BARDA Contract (Note 3) is recognized at a point in time. The Delivery Performance Obligation has been completed. With
respect to this performance obligation, revenue was recognized when BARDA obtained control of the asset, which was upon delivery to and acceptance by
the customer and at the point in time when the constraint on the consideration was resolved due to FDA approval of oral TPOXX®. The consideration,
which was variable consideration, was constrained until the FDA approved oral TPOXX® for the treatment of smallpox on July 13, 2018. Prior to FDA
approval,  consideration  had  been  constrained  because  the  FDA  Approval  Replacement  Obligation  (as  defined  in  Note  3)  had  not  been  quantified  or
specified. Following FDA approval, the possibility of having to replace product pursuant to the FDA Approval Replacement Obligation was essentially
eliminated and deemed to be remote since there was no difference between the approved product and the courses of oral TPOXX® that had been delivered
to the Strategic Stockpile.

34

Due  to  the  nature  of  the  work  required  to  be  performed  on  many  of  our  performance  obligations,  the  estimation  of  total  revenue  and  costs  to
satisfy  the  obligations  is  complex,  subject  to  many  variables  and  requires  significant  judgment.  The  consideration  associated  with  these  types  of
performance obligations is considered variable. We estimate variable consideration as the most likely amount to which we expect to be entitled. We include
estimated amounts in the transaction price to the extent it is probable that a significant reversal of cumulative revenue recognized will not occur and when
any  uncertainty  associated  with  variable  consideration  is  resolved.  Our  estimates  of  variable  consideration  and  determination  of  whether  to  include
estimated amounts in the transaction price are based largely on an assessment of our historical and anticipated performance, external factors, trends and all
other information (historical, current and forecasted) that is reasonably available to us.

Contracts are often modified to account for additional services to be performed. We consider contract modifications to exist when the modification
either creates new enforceable rights and obligations, or changes existing enforceable rights and obligations. If the effect of a contract modification on the
transaction  price  changes  our  measure  of  progress  for  the  performance  obligation  to  which  it  relates,  the  impact  will  be  recognized  in  the  period  of
modification as an adjustment to revenue (either as an increase in or a reduction of revenue) on a cumulative catch-up basis.

We have a process in which management reviews the progress and execution of our performance obligations. As part of this process, management
reviews information including, but not limited to, any outstanding key contract matters, progress towards completion and the related program schedule,
identified risks and opportunities and the related changes in estimates of revenues and costs. The risks and opportunities include management’s judgment
about  the  ability  and  cost  to  achieve  the  schedule,  technical  requirements  and  other  contract  requirements.  Management  must  make  assumptions  and
estimates regarding labor productivity, the complexity of the work to be performed, customer behavior and execution by our subcontractors, among other
variables.

Based on this analysis, any quarterly adjustments to revenues, research and development expenses and cost of sales and supportive services are
recognized as necessary in the period they become known. Changes in estimates of revenues, research and development expenses and cost of sales and
supportive services are recognized quarterly on a cumulative catch-up basis, which recognizes in the current period the cumulative effect of the changes on
current and prior periods based on a performance obligation’s percentage of completion. A significant change in one or more of these estimates could affect
the profitability of one or more of our performance obligations.

Income Taxes

Our income tax expense and, deferred tax assets and liabilities reflect management’s best estimate of current and future taxes to be paid. We are
subject to US federal income tax and state income tax in numerous jurisdictions. Significant judgments and estimates are required in the determination of
our income tax expense.

Deferred income taxes arise from temporary differences between the tax basis of assets and their reported amounts in the financial statements,
which will result in taxable or deductible amounts in the future. Each reporting period, we assess the realizability of our deferred tax assets to determine if
the  deductible  temporary  differences  will  be  utilized  on  a  more-likely-than-not  basis.  In  making  this  determination,  we  assess  all  available  positive  and
negative evidence to determine if our existing deferred tax assets are realizable on a more-likely-than-not basis. Significant weight is given to positive and
negative evidence that is objectively verifiable. We consider the reversal of existing taxable temporary differences, projected future taxable income, tax
planning  strategies  and  recent  financial  operating  results.  The  realization  of  a  deferred  tax  asset  is  ultimately  dependent  on  our  generation  of  sufficient
taxable income within the available net operating loss carryback and/or carryforward periods to utilize the deductible temporary differences. During the
year ended December 31, 2018, we received FDA approval and recorded revenue related to the delivery of our oral TPOXX® product. We also recorded
revenue related to the FDA holdback payment and the payment for 84-month expiry for oral TPOXX®. In addition, we entered into a new contract with
BARDA for the sale of up to 1.7 million courses of TPOXX®. Based on these factors, we determined that sufficient positive evidence existed to conclude
that substantially all of our deferred tax assets were realizable on a more-likely-than-not basis.

Table of Contents

35

The amount of deferred tax assets considered realizable, however, could be adjusted if estimates of future taxable income during the net operating
loss carryforward period change and/or if significant objective negative evidence is no longer present. Such changes could lead to a change in judgment
related to the realization of the net deferred tax asset. Future changes in the estimated amount of deferred taxes expected to be realized will be reflected in
our financial statements in the period the estimate is changed with a corresponding adjustment to operating results.

 
 
 
 
 
 
 
 
 
 
 
 
 
Income tax benefits are recognized for a tax position when, in management’s judgment, it is more likely than not that the position will be sustained
upon  examination  by  a  taxing  authority.  For  a  tax  position  that  meets  the  more-likely-than-not  recognition  threshold,  the  tax  benefit  is  measured  as  the
largest amount that is judged to have a greater than 50% likelihood of being realized upon ultimate settlement with a taxing authority. As of December 31,
2020, we recorded an uncertain tax position attributable to a reduction related to state net operating loss carryforwards. In the event that we conclude that
we are subject to interest and/or penalties arising from uncertain tax positions, we will present interest and penalties as a component of income taxes.

On  March  27,  2020,  the  Coronavirus  Aid,  Relief  and  Economic  Security  Act  (“CARES  Act”)  was  enacted  in  response  to  the  COVID-19
pandemic. Under ASC 740, the effects of changes in tax rates and laws are recognized in the period which the new legislation is enacted. The CARES Act
made various tax law changes, including among other things: (i) increasing the limitation under IRC Section 163(j) for 2019 and 2020 to permit additional
expensing  of  interest;  (ii)  enacting  a  technical  correction  so  that  qualified  improvement  property  can  be  immediately  expensed  under  IRC  Section
168(k); (iii) making modifications to the federal net operating loss rules including permitting federal net operating losses incurred in 2018, 2019, and 2020
to be carried back to the five preceding taxable years in order to generate a refund of previously paid income taxes; and (iv) enhancing recoverability of
AMT tax credit carryforwards.

In December 2019, the FASB issued ASU No. 2019-12, Simplifying the Accounting for Income Taxes, as part of its initiative to reduce complexity
in accounting standards. The amendments in the ASU are effective for fiscal years beginning after December 15, 2020, including interim periods therein.
Early adoption of the standard is permitted, including adoption in interim or annual periods for which financial statements have not yet been issued. The
Company is currently evaluating the effect, if any, that the ASU will have on its consolidated financial statements.

Warrant Liability

We  account  for  warrants  in  accordance  with  the  authoritative  guidance  which  requires  that  free-standing  derivative  financial  instruments  with
certain cash settlement features be classified as assets or liabilities at the time of the transaction, and recorded at their fair value. Fair value is estimated
using  a  model-derived  valuation.  Determining  the  fair  value  for  warrants  includes  the  expected  volatility  of  our  stock.  An  increase  or  decrease  in  the
expected  volatility  of  our  stock  of  10%  would  result  in  an  additional  gain  or  loss  of  approximately  $0.1  million.  Any  changes  in  the  fair  value  of  the
warrants are reported in earnings or loss as long as they are classified as assets or liabilities.

Recently Issued Accounting Pronouncements 

For  discussion  regarding  the  impact  of  accounting  standards  that  were  recently  issued  but  are  not  yet  effective,  on  our  consolidated  financial

statements, see Note 2, Summary of Significant Accounting Policies, to the consolidated financial statements.

Results of Operations for the Years ended December 31, 2020 and 2019

36

Revenues from product sales and supportive services for the years ended December 31, 2020 and 2019 were $115.5 million and $11.2 million,
respectively.  Such  revenues  for  the  year  ended  December  31,  2020  include  $112.6  million  of  revenue  related  to  the  delivery  and  acceptance  of
approximately 363,000 courses of oral TPOXX® to the Strategic Stockpile under the 19C BARDA Contract and $2.3 million of revenue related to courses
of oral TPOXX® that were delivered and accepted by the CDND. Such revenues for the year ended December 31, 2019 were associated with the delivery
and acceptance of approximately 35,700 courses of oral TPOXX® to the Strategic Stockpile under the 19C BARDA Contract. 

Revenues from research and development contracts and grants for the years ended December 31, 2020 and 2019, were $9.5 million and $15.6
million, respectively. The decrease of $6.1 million, or 39.0%, partially reflects the impact of a cumulative catch-up adjustment recognized during the year
ended December 31, 2019. During the year December 31, 2019, the Company completed its negotiation with representatives of the U.S. Government for a
change in the application of certain reimbursement rates in the contract. The change in the application of those reimbursement rates increased the overall
transaction price of the IV Formulation R&D Contract but did not change the estimate of costs to complete under the input method calculation.  As a result,
the Company accounted for this as a change in the transaction price and recognized a cumulative catch-up adjustment to revenue of approximately $3.3
million representing the impact of the change in the application of those reimbursement rates from January 2016 through March 2019. Additionally, the net
decrease  in  revenues  from  research  and  development  activities  reflects  a  $2.0  million  revenue  decrease  in  connection  with  a  decrease  in  direct  vendor-
related  costs  for  IV  TPOXX®  as  well  as  an  approximately  $0.8  million  revenue  decrease  associated  with  variability  in  connection  with  post-marketing
regulatory activities for oral TPOXX®. 

Cost of sales and supportive services for the years ended December 31, 2020 and 2019 were $14.8 million and $1.8 million, respectively. Such
costs in 2020 and 2019 were associated with the manufacture and delivery of approximately 366,000 and 35,700 courses of oral TPOXX®, respectively.
The change in gross margin (cost of sales as a percentage of product sales) is primarily attributable to pricing differences between countries, as well as an
update to the terms of production agreements. 

Selling, general and administrative expenses for the years ended December 31, 2020 and 2019 were $14.0 million and $13.3 million, respectively,
reflecting an increase of $0.7 million, or 5.7%. The increase primarily reflects the commission expense associated with the sale of oral TPOXX® to the
CDND in May 2020 as well as higher regulatory costs associated with our submission of a Marketing Authorisation Application (MAA) with the European
Medicines  Agency  for  oral  TPOXX®  and  increased  insurance  costs,  which  were  only  partially  offset  by  a  decrease  of  $0.4  million  in  compensation
expense.

Research  and  development  expenses  were  $10.9  million  for  the  year  ended  December  31,  2020,  a  decrease  of  approximately  $2.4  million,
or 17.8% from the $13.3 million incurred during the year ended December 31, 2019. The decrease is primarily attributable to a decrease in direct vendor-
related expenses supporting the development of IV TPOXX® as well as a decrease in direct-related expenses supporting the performance of post-marketing
regulatory activities for oral TPOXX®. 

Patent expenses for the years ended December 31, 2020 and 2019 were $0.7 million and $0.7 million, respectively. These expenses reflect our

ongoing efforts to protect our lead drug candidates in varied geographic territories.

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
In connection with the voluntary repayment of the Term Loan on March 13, 2020, we recognized a loss on the extinguishment of the Term Loan of

approximately $5.0 million for the year ended December 31, 2020.

Interest expense on the term loan facility under the Loan Agreement (the "Term Loan") for the year ended December 31, 2020 was $3.0 million,
a decrease of approximately $12.8 million from the $15.8 million incurred during the year ended December 31, 2019. The $3.0 million of interest for the
year ended December 31, 2020 includes $0.9 million of accretion of unamortized costs and fees (prior to repayment of the Term Loan). The $15.8 million
of interest for the year ended December 31, 2019 includes $4.5 million of accretion of unamortized costs and fees related to the Term Loan balance.

Changes  in  the  fair  value  of  the  liability  classified  warrant  to  acquire  common  stock  were  recorded  within  the  income  statement.  For  the  year
ended  December  31,  2020,  we  recorded  a  loss  of  approximately  $3.5  million  reflecting  an  increase  in  the  fair  value  of  the  liability-classified  warrant
primarily  due  to  an  increase  in  our  stock  price.  For  the  year  ended  December  31,  2019,  we  recorded  a  gain  of  approximately  $5.1  million  reflecting  a
decrease in fair value of the liability-classified warrant primarily due to the decrease in the price of our common stock.

Other  income,  net  for  the  years  ended  December  31,  2020  and  2019  was  $0.5  million  and  $2.8  million,  respectively.  Other  income
primarily reflects interest income on the Company's cash balance held in restricted and unrestricted accounts. The decrease of approximately $2.3 million is
driven by lower cash balances during the year as well as lower interest rates for 2020 when compared to 2019. 

For the year ended December 31, 2020, we recognized a tax provision of $17.2 million on pre-tax income of $73.5 million. Our effective tax rate
for the year ended December 31, 2020 was 23.4%. For the year ended December 31, 2020, our effective tax rate differs from the statutory rate of 21%
primarily  as  a  result  of  a  non-taxable  adjustment  for  the  fair  market  value  of  the  Warrant,  non-deductible  executive  compensation  under  IRC  Section
162(m), and state taxes.

For the year ended December 31, 2019, we recognized a tax benefit of approximately $2.9 million on a pre-tax loss of $10.2 million. Our effective
tax rate for the year ended December 31, 2019 was 28.9%. For the year ended December 31, 2019, our effective tax rate differs from the statutory rate of
21% primarily as a result of a non-taxable adjustment for the fair market value of the Warrant, partially offset by non-deductible executive compensation
under IRC Section 162(m).

Liquidity and Capital Resources

As of December 31, 2020, we had $117.9 million in cash and cash equivalents, compared with $65.2 million at December 31, 2019. Additionally,
in comparison to $95.7 million of restricted cash and cash equivalents at December 31, 2019, there was no restricted cash as of December 31, 2020 given
that the Term Loan was repaid in March 2020. The restricted cash and cash equivalents were available to pay interest, fees and principal on the Term Loan.
The Company voluntarily prepaid the Term Loan on March 13, 2020 in an approximate amount of $87.2 million, including accrued interest. As a result of
repayment of the Term Loan, there are no restrictions on the use of our cash and cash equivalents.

Operating Activities

We prepare our consolidated statement of cash flows using the indirect method. Under this method, we reconcile net income (loss) to cash flows
from operating activities by adjusting net (loss) income for those items that impact net income (loss) but may not result in actual cash receipts or payments
during the period. These reconciling items include but are not limited to stock-based compensation and changes in the fair value of our warrant liability;
gains and losses from various transactions and changes in the consolidated balance sheet for working capital from the beginning to the end of the period.

Net cash provided by (used in) operations for the years ended December 31, 2020 and 2019 was $71.5 million and $(18.2) million, respectively.
  For  the  year  ended  December  31,  2020,  the  receipt  of  approximately  $114.9  million  for  product  delivery  and  acceptance  of  oral  TPOXX®  courses
delivered to the SNS and CDND was partially offset by net cash usage primarily related to manufacturing of inventory and customary operating activities.
For the year ended December 31, 2019, we incurred $11.3 million of cash interest expense on the Term Loan and used approximately $10.6 million in
support  of  ordinary  course  working  capital  (accounts  receivable,  accounts  payable,  prepaids,  among  other  items).  Additionally,  cash  was  used  for
customary  operating  activities.  These  cash  uses  were  partially  offset  by  the  receipt  of  approximately  $11.1  million  from  BARDA  for  product  delivery;
$15.5 million from R&D contracts; and $2.8 million of interest income.

On December 31, 2020 and 2019, our accounts receivable balance was approximately $3.3 million (which includes approximately $1.3 million of
unbilled  receivables)  and  $4.2  million,  respectively.  Our  accounts  receivable  balances  primarily  reflect  work  that  is  reimbursable  by  BARDA  and  was
performed during December 31, 2020 and 2019, respectively, in connection with TPOXX®.

Investing Activities

Net cash used in investing activities for the years ended December 31, 2020 and 2019 was $15,501 and $29,094, respectively. In 2020 and 2019,

net cash used related to capital expenditures. 

Financing Activities

Net cash used in financing activities for the years ended December 31, 2020 and 2019 was $114.6 million and $1.2 million, respectively. For the
year  ended  December  31,  2020,  $85.9  million  was  associated  with  our  voluntary  prepayment  of  the  Term  Loan  and  approximately  $28.5  million  was
associated with the repurchase of approximately 4.6 million shares of common stock. For the year ended December 31, 2019, $1.2 million was attributable
to the payment of tax obligations for employee common stock tendered.

Item 7A. Quantitative and Qualitative Disclosures About Market Risk

39

Our investment portfolio includes cash and cash equivalents. Our main investment objective is the preservation of investment capital. We believe
that  our  investment  policy  is  conservative,  both  in  the  duration  of  our  investments  and  the  credit  quality  of  the  investments  we  hold.  We  do  not  utilize
derivative financial instruments, derivative commodity instruments or other market risk sensitive instruments, positions or transactions to manage exposure
to interest rate changes. As such, we believe that, the securities we hold are subject to market risk, changes in the financial standing of the issuer of such
securities and our interest income is sensitive to changes in the general level of U.S. interest rates. Additionally, we are subject to the impact of stock price
fluctuations of our common stock in that we have a liability-classified warrant in which 1.0 million shares of SIGA common stock can be purchased at a
strike  price  of  $1.50  per  share.  For  every  $1  increase  in  the  stock  price  of  SIGA,  the  intrinsic  value  of  the  liability-classified  warrant  will  increase  by
approximately $1.0 million.

Report of Independent Registered Public Accounting Firm

To the Board of Directors and Stockholders of SIGA Technologies, Inc.

Opinion on the Financial Statements

We have audited the accompanying consolidated balance sheets of SIGA Technologies, Inc. and its subsidiaries (the “Company”) as of December 31, 2020
and 2019, and the related consolidated statements of operations and comprehensive income (loss), of changes in stockholders’ equity/(deficiency) and of
cash flows for each of the three years in the period ended December 31, 2020, including the related notes (collectively referred to as the “consolidated
financial statements”). In our opinion, the consolidated financial statements present fairly, in all material respects, the financial position of the Company as
of December 31, 2020 and 2019, and the results of its operations and its cash flows for each of the three years in the period ended December 31, 2020 in
conformity with accounting principles generally accepted in the United States of America. 

Changes in Accounting Principles

As discussed in Note 2 to the consolidated financial statements, the Company changed the manner in which it accounts for leases in 2019 and the manner in
which it accounts for revenues from contracts with customers in 2018.

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 audits of these consolidated financial statements in accordance with the standards of the PCAOB. Those standards require that we plan
and perform the audit to obtain reasonable assurance about whether the consolidated financial statements are free of material misstatement, whether due to
error or fraud. The Company is not required to have, nor were we engaged to perform, an audit of its internal control over financial reporting. As part of our
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 that 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 (i) relates to accounts or disclosures that are material to the consolidated
financial statements and (ii) involved our especially challenging, subjective, or complex judgments. The communication of critical audit matters does not
alter in any way our opinion on the consolidated financial statements, taken as a whole, and we are not, by communicating the critical audit matter below,
providing a separate opinion on the critical audit matter or on the accounts or disclosures to which it relates.

Revenue Recognition – Estimated Costs to Complete the Research and Development Services (“R&D”) Performance Obligations for the 19C BARDA and
IV Formulation R&D Contracts

As discussed in Notes 2 and 3 to the consolidated financial statements, all of the Company’s revenue for the year ended December 31, 2020 was generated
from long-term contracts. For these contracts, all revenue associated with R&D performance obligations for the 19C BARDA and IV Formulation R&D
Contracts, which totaled approximately $7.5 million and $1.4 million respectively, is recognized over time, because the customer simultaneously receives
and consumes the benefits provided by the services as the Company performs these services. Management recognizes revenue based on the progress toward
complete satisfaction of the performance obligation and measures this progress under an input method, which is based on the Company’s costs incurred
relative to total estimated costs. Under this method, progress is measured based on the cost of resources consumed compared to the total estimated costs to
completely satisfy the performance obligation. As disclosed by management, due to the nature of the work required to be performed on many of the
performance obligations, management’s estimation of total revenue and costs to satisfy the obligations is complex, subject to many variables, and requires
significant judgment. The incurred and estimated costs used in the measure of progress include third-party services performed, direct labor hours, and
material consumed.

The principal considerations for our determination that performing procedures relating to revenue recognition – estimated costs to complete the R&D
performance obligations for the 19C BARDA and IV Formulation R&D Contracts is a critical audit matter are the significant judgment by management
when determining the estimated costs to completely satisfy the performance obligations. This in turn led to significant auditor judgment, subjectivity and
effort in performing procedures and in evaluating the estimates of the costs to complete related to management’s estimates of total forecasted costs.

Addressing the matter involved performing procedures and evaluating audit evidence in connection with forming our overall opinion on the consolidated
financial statements. These procedures included, among others, evaluating and testing management’s process for determining the estimated costs to
completely satisfy each performance obligation for the 19C BARDA and IV Formulation R&D Contracts, which included evaluating the reasonableness of
management’s estimates of total forecasted costs. Evaluating the reasonableness of management’s estimates of total forecasted costs involved assessing
management’s ability to reasonably estimate costs to complete the performance obligation by (i) comparing, on a test basis, the underlying cost estimates to
approved contracts or modifications; (ii) comparing, on a test basis, the underlying transaction price to original contracts or modifications; and (iii) testing
actual costs incurred and their eligibility for billing under the research and development performance obligations.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

1. Organization and Basis of Presentation

Description of Business
SIGA  Technologies,  Inc.  (“SIGA”  or  the  “Company”)  is  a  commercial-stage  pharmaceutical  company.  The  Company's  lead  product,  TPOXX®  (“oral
TPOXX®”) is a United States Food & Drug Administration-approved oral formulation antiviral drug for the treatment of human smallpox disease caused
by variola virus. On July 13, 2018, the FDA approved oral TPOXX®.

2. Summary of Significant Accounting Policies

Use of Estimates
Management is required to make estimates and assumptions that affect the reported amounts of assets and liabilities, the disclosure of contingent assets and
liabilities at the date of the financial statements and revenues and expenses during the periods reported. The most significant estimates include the variables
used in the calculation of fair value of warrants granted or issued by the Company, reported amounts of revenue, and the valuation of deferred tax assets.
Estimates and assumptions are reviewed periodically and the effects of revisions are reflected in the financial statements in the period they are determined
to be necessary. Actual results could differ from these estimates.

Basis of Presentation
The  consolidated  financial  statements  and  related  disclosures  are  presented  in  accordance  with  generally  accepted  accounting  principles  in  the  United
States of America (“US GAAP”) and reflect the consolidated financial position, results of operations and cash flows for all periods presented.

Cash Equivalents
The Company considers all highly liquid investments with original maturities of three months or less to be cash equivalents.

Restricted Cash and Cash Equivalents
Under the terms of the Loan Agreement (as defined below), net cash proceeds from the Company's Priority Review Voucher ("PRV") sale on October 31,
2018 (see Note 4) were restricted and were held in a reserve account. Cash and cash equivalents held in the reserve account were available to pay interest,
fees and principal related to the Term Loan (see Note 8 for additional information). Prior to the second quarter of 2020, there was also a reserve account for
certain proceeds of the Loan Agreement. This account was also restricted. Amounts in this reserve account were primarily used to pay interest on the Loan
Agreement. This reserve account was closed in the second quarter of 2020.

The following table reconciles cash, cash equivalents and restricted cash per the consolidated statements of cash flows to the consolidated balance sheet for
each respective period:

Table of Contents

Accounts Receivable
Accounts  receivable  are  recorded  net  of  provisions  for  doubtful  accounts.  At  December  31,  2020  and  2019,  100%  of  accounts  receivable  represented
receivables from the U.S. Government. An allowance for doubtful accounts is based on specific analysis of the receivables. At December 31, 2020 and
2019, the Company had no allowance for doubtful accounts.

Inventory
Inventory is stated at the lower of cost or net realizable value. The Company capitalizes inventory costs associated with the Company’s products when,
based on management’s judgment, future commercialization is considered probable and the future economic benefit is expected to be realized; otherwise,
such  costs  are  expensed  as  research  and  development.  Inventory  is  evaluated  for  impairment  periodically  to  identify  inventory  that  may expire  prior  to
expected sale or has a cost basis in excess of its net realizable value. If certain batches or units of product no longer meet quality specifications or become
obsolete due to expiration, the Company records a charge to write down such unmarketable inventory to its net realizable value.

Property, Plant and Equipment
Property, plant and equipment are stated at cost, net of accumulated depreciation. Depreciation is provided on a straight-line method over the estimated
useful lives of the various asset classes. The estimated useful lives are as follows: five years for laboratory equipment; three years for computer equipment;
and seven years for furniture and fixtures. Leasehold improvements are amortized over the shorter of the estimated useful lives of the assets or the lease
term. Maintenance, repairs and minor replacements are charged to expense as incurred.

Warrant Liability
The Company accounts for warrants in accordance with the authoritative guidance which requires that free-standing derivative financial instruments with
certain cash settlement features be classified as assets or liabilities at the time of the transaction, and recorded at their fair value. Fair value is estimated
using  model-derived  valuations.  Any  changes  in  the  fair  value  of  the  derivative  instruments  are  reported  in  earnings  or  loss  as  long  as  the  derivative
contracts are classified as assets or liabilities.

Revenue Recognition
All of the Company’s revenue is derived from long-term contracts that span multiple years. The Company accounts for revenue in accordance with ASC
Topic 606, Revenue from Contracts with Customers (“ASC 606”).

Adoption of ASC 606. On January 1, 2018, the Company adopted ASC 606 using the modified retrospective method applied to those contracts

that were not completed as of January 1, 2018. 

The  cumulative  impact  of  adopting  ASC  606  as  of  January  1,  2018  was  a  decrease  to  deferred  revenue  of  approximately  $1.8  million;  a  decrease  to
deferred costs of approximately $2.1 million; an increase to receivables of approximately $0.1 million and a net increase to opening accumulated deficit of
$0.2 million, net of tax. For the year ended December 31, 2018, the impact to revenues as a result of applying ASC 606 was an increase of approximately
$1.0 million.

Performance Obligations. A performance obligation is a promise in a contract to transfer a distinct good or service to the customer, and is the
unit of account in ASC 606. A contract’s transaction price is allocated to each distinct performance obligation and recognized as revenue when, or as, the
performance obligation is satisfied. As of December 31, 2020, the Company's active performance obligations, for the contracts outlined in Note 3, consist
of the following: six performance obligations relate to research and development services; one relates to manufacture and delivery of product; and one is
associated with storage of product.

Contract  modifications  may occur  during  the  course  of  performance  of  our  contracts.  Contracts  are  often  modified  to  account  for  changes  in  contract
specifications or requirements. In most instances, contract modifications are for services that are not distinct, and, therefore, are accounted for as part of the
existing contract.

The Company’s performance obligations are satisfied over time as work progresses or at a point in time. All of the Company’s revenue related to current
research  and  development  performance  obligations  is  recognized  over  time,  because  the  customer  simultaneously  receives  and  consumes  the  benefits
provided by the services as the Company performs these services. The Company recognizes revenue related to these services based on the progress toward
complete satisfaction of the performance obligation and measures this progress under an input method, which is based on the Company’s cost incurred
relative  to  total  estimated  costs.  Under  this  method,  progress  is  measured  based  on  the  cost  of  resources  consumed  (i.e.,  cost  of  third-party  services
performed, cost of direct labor hours incurred, and cost of materials consumed) compared to the total estimated costs to completely satisfy the performance
obligation. Incurred costs represent work performed, which corresponds with, and thereby best depicts, the transfer of control to the customer. The incurred
and estimated costs used in the measure of progress include third-party services performed, direct labor hours, and material consumed.

Table of Contents

Revenue  connected  with  the  performance  obligations  related  to  the  delivery  of  oral  TPOXX®  to  the  U.S.  Strategic  National  Stockpile  ("Strategic
Stockpile") ("Delivery Performance Obligation") is recognized at a point in time. The Delivery Performance Obligation under the 2011 BARDA Contract
(Note 3)  has  been  completed.  With  respect  to  this  performance  obligation,  revenue  was  recognized  when  the  U.S.  Biomedical  Advanced  Research  and
Development Authority ("BARDA") obtained control of the asset, which was upon delivery to and acceptance by the customer and at the point in time
when the constraint on the consideration was resolved due to FDA approval of oral TPOXX®. The consideration, which was variable consideration, was
constrained  until  the  FDA  approved  oral  TPOXX®  for  the  treatment  of  smallpox  on  July  13,  2018.  Prior  to  FDA  approval,  consideration  had  been
constrained because the FDA Approval Replacement Obligation (as defined in Note 3) had not been quantified or specified. Following FDA approval, the
possibility of having to replace product pursuant to the FDA Approval Replacement Obligation was essentially eliminated and deemed to be remote since
there was no difference between the approved product and the courses of oral TPOXX® that had been delivered to the Strategic Stockpile.

Contract Estimates. Accounting for long-term contracts and grants involves the use of various techniques to estimate total contract revenue and

costs.

Contract  estimates  are  based  on  various  assumptions  to  project  the  outcome  of  future  events  that  often  span  multiple  years. These  assumptions  include
labor  productivity;  the  complexity  of  the  work  to  be  performed;  external  factors  such  as  customer  behavior  and  potential  regulatory  outcomes;  and  the
performance of subcontractors, among other variables.

The  nature  of  the  work  required  to  be  performed  on  many  of  the  Company’s  performance  obligations  and  the  estimation  of  total  revenue  and  cost  at
completion are complex, subject to many variables and require significant judgment. The consideration associated with research and development services
is variable as the total amount of services to be performed has not been finalized. The Company estimates variable consideration as the most likely amount
to which it expects to be entitled. The Company includes estimated amounts in the transaction price to the extent it is probable that a significant reversal of
cumulative revenue recognized will not occur and when any uncertainty associated with variable consideration is resolved. The Company’s estimates of
variable  consideration  and  determination  of  whether  to  include  estimated  amounts  in  the  transaction  price  are  based  largely  on  an  assessment  of  our
historical and anticipated performance, external factors, trends and all other information (historical, current and forecasted) that is reasonably available to
us.

A significant change in one or more of these estimates could affect the profitability of the Company’s contracts. As such, the Company reviews and updates
its contract-related estimates regularly. The Company recognizes adjustments in estimated revenues, research and development expenses and cost of sales
and supportive services under the cumulative catch-up method. Under this method, the impact of the adjustment on revenues, research and development
expenses and cost of sales and supportive services recorded to date on a contract is recognized in the period the adjustment is identified.

As discussed in Note 3, during the year ended December 31, 2019, the Company recognized a cumulative catch-up adjustment to revenue of approximately
$3.3 million related to the negotiation with representatives of the U.S. Government for a change in the application of certain reimbursement rates under the
IV Formulation R&D Contract (defined in Note 3).

Contract Balances. The timing of revenue recognition, billings and cash collections may result in billed accounts receivable, unbilled receivables
(contract  assets)  and  customer  advances  and  deposits  (contract  liabilities)  in  the  consolidated  balance  sheets.  Generally,  amounts  are  billed  as  work
progresses in accordance with agreed-upon contractual terms either at periodic intervals (monthly) or upon achievement of contractual milestones; as of
December  31,  2020,  the  accounts  receivable  balance  in  the  balance  sheet  includes  approximately  $1.3  million  of  unbilled  receivables.  Under  typical
payment terms of fixed price arrangements, the customer pays the Company either performance-based payments or progress payments. For the Company’s
cost-type  arrangements,  the  customer  generally  pays  the  Company  for  its  actual  costs  incurred,  as  well  as  its  allocated  overhead  and  G&A  costs.  Such
payments occur within a short period of time from billing. When the Company receives consideration, or such consideration is unconditionally due, prior to
transferring  goods  or  services  to  the  customer  under  the  terms  of  a  sales  contract,  the  Company  records  deferred  revenue,  which  represents  a  contract
liability.  During  the  year  ended  December  31,  2020,  the  Company  recognized  revenue  of  $0.1  million  that  was  included  in  deferred  revenue  at  the
beginning of the period.

Remaining  Performance  Obligations.  Remaining  performance  obligations  represent  the  transaction  price  for  which  work  has  not  been
performed  and  excludes  unexercised  contract  options.  As  of  December  31,  2020,  the  aggregate  amount  of  transaction  price  allocated  to  remaining
performance obligations was $63.5 million. The Company expects to recognize this amount as revenue within the next five years as the specific timing for
satisfying the performance obligations is subjective and outside the Company’s control.

Leases
The Company accounts for leases in accordance with ASC 842, Leases (“ASC 842”)

50

 
 
 
 
 
 
 
 
 
 
Table of Contents

Adoption of ASC 842. On January 1, 2019, the Company adopted ASC 842 using the modified retrospective approach as of the effective date of
the standard without revising prior periods. In addition, the Company elected the package of practical expedients permitted under the transition guidance
within  the  new  standard,  which  among  other  things,  allowed  the  Company  to  carry  forward  its  historical  lease  classification.  In  addition,  the  Company
elected  the  hindsight  practical  expedient  to  determine  the  lease  term  for  existing  leases.  The  Company’s  election  of  the  hindsight  practical  expedient
resulted in the extension of the Oregon lease term as it was determined that the first renewal option under this lease was expected to be exercised with a
reasonable degree of certainty. In the second quarter of 2019, the Company exercised the first renewal option under the Oregon lease. The Company was
required  to  record  an  operating  lease  right-of-use  ("ROU")  asset  and  a  corresponding  operating  lease  liability,  equal  to  the  present  value  of  the  lease
payments at the adoption date. In the determination of future lease payments, the Company has elected to aggregate lease components such as payments for
rent, taxes and insurance costs with non-lease components such as maintenance costs and account for these payments as a single lease component. The
present value of the lease payments was determined using the Company's incremental borrowing rate. The impact of adopting ASC 842 as of January 1,
2019 was the recording of operating lease right-of-use assets of approximately $2.9 million; the recording of operating lease liabilities of approximately
$3.3 million; and a decrease to deferred rent of approximately $0.4 million.

The Company determines if an arrangement is a lease at inception. Leases with an initial term less than one year are not recorded on the balance sheet and
the lease costs are recorded as an expense on a straight-line basis over the lease term. Operating leases with terms greater than one year result in a lease
liability recorded in other liabilities with a corresponding ROU asset recorded in property, plant and equipment.

Operating lease liabilities are recognized at the commencement date based on the present value of future minimum lease payments over the lease term.
ROU assets are recognized based on the corresponding lease liabilities adjusted for qualifying initial direct costs, prepaid or accrued lease payments and
unamortized lease incentives. The Company has lease agreements with lease and non-lease components, which are accounted for as a single lease. Lease
terms may include options to extend or terminate the lease which are incorporated into the Company's measurement when it is reasonably certain that the
Company will exercise the option.

Research and Development
Research  and  development  expenses  include  costs  directly  and  indirectly  attributable  to  the  conduct  of  research  and  development  programs,  and
performance pursuant to the BARDA contracts, including employee related costs, materials, supplies, depreciation on and maintenance of equipment, the
cost of services provided by outside contractors, including services related to the Company’s clinical trials and facility costs, such as rent, utilities, and
general support services. All costs associated with research and development are expensed as incurred. Costs related to the acquisition of technology rights,
for which development work is still in process, and that have no alternative future uses, are expensed as incurred.

Goodwill
The Company evaluates goodwill for impairment at least annually or as circumstances warrant. The impairment review process compares the fair value of
the reporting unit in which goodwill resides to its carrying value. The Company operates as one business and one reporting unit. Therefore, the goodwill
impairment analysis is performed on the basis of the Company as a whole, using the market capitalization of the Company as an estimate of its fair value.

Share-based Compensation
Stock-based  compensation  expense  for  all  share-based  payment  awards  made  to  employees  and  directors  is  determined  on  the  grant  date;  for  options
awards,  fair  value  was  estimated  using  the  Black-Scholes  model.  These  compensation  costs  are  recognized  net  of  an  estimated  forfeiture  rate  over  the
requisite  service  periods  of  the  awards.  Forfeitures  are  estimated  on  the  date  of  the  respective  grant  and  revised  if  actual  or  expected  forfeiture  activity
differs from original estimates.

Income Taxes
The Company recognizes income taxes utilizing the asset and liability method of accounting for income taxes. Under this method, deferred income taxes
are recorded for temporary differences between financial statement carrying amounts and the tax basis of assets and liabilities at enacted tax rates expected
to be in effect for the years in which the differences are expected to reverse. A valuation allowance is established if it is more likely than not that some or
the entire deferred tax asset will not be realized. The recognition of a valuation allowance for deferred taxes requires management to make estimates and
judgments  about  the  Company’s  future  profitability  which  are  inherently  uncertain.  The  Company  may  recognize  tax  benefits  from  an  uncertain  tax
position only if it is more likely than not that the tax position will be sustained on examination by the taxing authorities based on the technical merits of the
position. The tax benefits recognized in the financial statements from such position should be measured based on the largest benefit that has a greater than
fifty percent likelihood of being realized upon ultimate settlement. The Company re-evaluates uncertain tax positions and considers factors, including, but
not limited to, changes in tax law, the measurement of tax positions taken or expected to be taken on tax returns, and changes in circumstances related to a
tax position. The Company recognizes interest and penalties related to income tax matters in income tax expense.

Repurchase of shares
When  shares  recognized  as  equity  are  repurchased,  the  amount  of  the  consideration  paid,  which  includes  directly  attributable  costs,  is  recognized  as  a
deduction from equity. The excess of the purchase price above par value of repurchased shares that are retired is presented as an increase to accumulated
deficit (or a reduction of retained earnings, if any).

(Loss) Earnings per Share
Basic  earnings  per  share  is  computed  by  dividing  net  (loss)  income  by  the  weighted-average  number  of  common  shares  outstanding  during  the  period.
Diluted earnings per share is computed by dividing net (loss) income by the weighted-average number of common shares outstanding during the period,
assuming  potentially  dilutive  common  shares  from  option  exercises,  SSARs,  RSUs,  warrants  and  other  incentives  had  been  issued  and  any  proceeds
received in respect thereof were used to repurchase common stock at the average market price during the period. The assumed proceeds used to repurchase
common  stock  is  the  sum  of  the  amount  to  be  paid  to  the  Company  upon  exercise  of  options  and  the  amount  of  compensation  cost  attributed  to  future
services not yet recognized.

Fair Value of Financial Instruments
The  carrying  value  of  cash  and  cash  equivalents,  restricted  cash  and  cash  equivalents,  accounts  receivable,  accounts  payable  and  accrued  expenses  and
other current liabilities approximates fair value due to the relatively short maturity of these instruments. Common stock warrants which are classified as
liabilities are recorded at their fair market value as of each reporting period.

The measurement of fair value requires the use of techniques based on observable and unobservable inputs. Observable inputs reflect market data obtained
from independent sources, while unobservable inputs reflect our market assumptions. The inputs create the following fair value hierarchy:

•

•

•

Level 1 – Quoted prices for identical instruments in active markets.

Level 2 – Quoted prices for similar instruments in active markets; quoted prices for identical or similar instruments in markets that are not active;
and model-derived valuations where inputs are observable or where significant value drivers are observable.

Level 3 – Instruments where significant value drivers are unobservable to third parties.

The Company uses model-derived valuations where certain inputs are unobservable to third parties to determine the fair value of common stock warrants
on a recurring basis and classifies the liability-classified warrant as Level 3.

The Company used a discounted cash flow model to estimate the fair value of the debt by applying a discount rate to future payments expected to be made
as  set  forth  in  the  Loan  Agreement.    The  fair  value  of  the  loan  was  measured  using  Level  3  inputs.    The  discount  rate  was  determined  using  market
participant assumptions.

There were no transfers between levels of the fair value hierarchy during 2020 or 2019. As of December 31, 2020, the Company had approximately $0.1
million of cash and cash equivalents classified as Level 1 financial instruments. There were no Level 2 financial instruments as of December 31, 2020. As
of December 31, 2019, the Company had approximately $5.6 million and $90.0 million of restricted cash and cash equivalents classified as Level 1 and
Level 2 financial instruments, respectively.

The following table presents changes in the liability-classified warrant measured at fair value using Level 3 inputs:

Loss Contingencies
The Company is subject to certain contingencies arising in the ordinary course of business. The Company records accruals for these contingencies to the
extent that a loss is both probable and reasonably estimable. If some amount within a range of loss appears to be a better estimate than any other amount
within the range, that amount is accrued. Alternatively, when no amount within a range of loss appears to be a better estimate than any other amount, the
lowest amount in the range is accrued. The Company expenses legal costs associated with loss contingencies as incurred. We record anticipated recoveries
under existing insurance contracts when recovery is assured.

Segment Information
The Company is managed and operated as one business. The entire business is managed by a single management team that reports to the chief executive
officer, who is the Chief Operating Decision Maker. The Company does not operate separate lines of business or separate business entities with respect to
any  of  its  product  candidates.  Accordingly,  the  Company  does  not  prepare  discrete  financial  information  with  respect  to  separate  product  areas  or  by
location and has only one reportable segment.

Recent Accounting Pronouncements
In June 2016, the FASB issued ASU No. 2016- 13, Financial Instruments - Credit Losses: Measurement of Credit Losses on Financial Instruments ("ASU
2016- 13"). ASU 2016- 13 requires an entity to measure and recognize expected credit losses for certain financial instruments, including trade receivables,
as an allowance that reflects the entity's current estimate of credit losses expected to be incurred. The standard is effective for fiscal years, and interim
periods within those fiscal years, beginning after December 15, 2019, with early adoption permitted. The adoption of this standard had no impact on the
consolidated financial statements.

In December  2019,  the  FASB  issued  ASU  No. 2019-12, Simplifying  the  Accounting  for  Income  Taxes,  as  part  of  its  initiative  to  reduce  complexity  in
accounting  standards.  The  amendments  in  the  ASU  are  effective  for  fiscal  years  beginning  after  December 15, 2020, including  interim  periods  therein.
Early adoption of the standard is permitted, including adoption in interim or annual periods for which financial statements have not yet been issued. The
Company is currently evaluating the effect, if any, that the ASU will have on its consolidated financial statements.

3. Procurement Contract and Research Agreements

19C BARDA Contract

On September 10, 2018, the  Company  entered  into  a  contract  with  BARDA  pursuant  to  which  SIGA  agreed  to  deliver  up  to  1,488,000  courses  of  oral
TPOXX®  to  the  Strategic  Stockpile,  and  to  manufacture  and  deliver  to  the  Strategic  Stockpile,  or  store  as  vendor-managed  inventory,  up  to  212,000
courses  of  the  intravenous  (IV)  formulation  of  TPOXX®  (“IV  TPOXX®”).  Additionally,  the  contract  includes  funding  from  BARDA  for  advanced
development of IV TPOXX®, post-marketing activities for oral and IV TPOXX®, and procurement activities. As of December 31, 2020, the contract with
BARDA (as amended, modified, or supplemented from time to time, the "19C BARDA Contract") contemplates up to approximately $602.5 million of
payments,  of  which  approximately  $51.7  million  of  payments  are  included  within  the  base  period  of  performance  of  five  years,  approximately  $127.1
million of payments are related to exercised options and up to approximately $423.7 million of payments are currently specified as unexercised options.
BARDA may choose in its sole discretion when, or whether, to exercise any of the unexercised options. The period of performance for options is up to ten
years from the date of entry into the 19C BARDA Contract and such options could be exercised at any time during the contract term, including during the
base period of performance. 

The base period of performance specifies potential payments of approximately $51.7 million for the following activities: payments of approximately $11.1
million  for  the  delivery  of  approximately  35,700  courses  of  oral  TPOXX®  to  the  Strategic  Stockpile;  payments  of  $8.0  million  for  the  manufacture
of  20,000  courses  of  final  drug  product  of  IV  TPOXX®  ("IV  FDP"),  of  which  $3.2  million  of  payments  are  related  to  the  manufacture  of  bulk  drug
substance ("IV BDS") to be used in the manufacture of IV FDP; payments of approximately $32.0 million to fund advanced development of IV TPOXX®;
and payments of approximately $0.6 million for supportive procurement activities. As of December 31, 2020, the Company had received or billed for $11.1
million for the successful delivery of approximately 35,700 courses of oral TPOXX® to the Strategic Stockpile, $3.2 million for the manufacture of IV
BDS and $9.7 million for other base period activities. IV BDS is expected to be used for the manufacture of 20,000 courses of IV FDP. The $3.2 million
received for the manufacture of IV BDS has been recorded as deferred revenue as of  December 31, 2020 and December 31, 2019; such amount is expected
to be recognized as revenue when IV TPOXX® containing such IV BDS is delivered to the Strategic Stockpile or placed in vendor-managed inventory.

The  options  that  have  been  exercised  to  date  provide  for  payments  up  to  approximately  $127.1  million.  There  are  exercised  options  for  the  following
activities: payments up to $11.2 million for the procurement of raw materials to be used in the manufacture of at least 363,070 courses of oral TPOXX®,
payments  up  to  $101.3  million  for  the  delivery  of  up  to  363,070  courses  of  oral  TPOXX®;  and,  payments  of  up  to  $14.6  million  for  funding  of  post-
marketing activities for oral TPOXX®. As of December 31, 2020, the Company has received the following payments in connection with exercised options:
$11.2 million was received for the procurement of raw materials and such amount was initially recorded as deferred revenue and was recognized as revenue
during  the  year  ended  December  31,  2020,  with  deliveries  of  approximately  363,000  courses,  in  the  aggregate,  of  oral  TPOXX®;  $101.3  million  was
received in connection with the June, September and October deliveries, in total, of approximately 363,000 courses of oral TPOXX®; and $5.4 million has
been received or billed for in connection with post-marketing activities for oral TPOXX®.

Unexercised options specify potential payments up to approximately $423.7 million in total (if all such options are exercised). There are options for the
following  activities:  payments  of  up  to  $337.7  million  for  the  delivery  of  up  to  approximately  1,089,000  courses  of  oral  TPOXX®  to  the  Strategic
Stockpile; payments of up to $76.8 million for the manufacture of up to 192,000 courses of IV FDP, of which up to $30.7 million of payments would be
paid upon the manufacture of IV BDS to be used in the manufacture of IV FDP; payments of up to approximately $3.6 million to fund post-marketing
activities for IV TPOXX®; and payments of up to approximately $5.6 million for supportive procurement activities.

Table of Contents

The options related to IV TPOXX® are divided into two primary manufacturing steps. There are options related to the manufacture of bulk drug substance
(“IV  BDS  Options”),  and  there  are  corresponding  options  (for  the  same  number  of  IV  courses)  for  the  manufacture  of  final  drug  product  (“IV  FDP
Options”). BARDA may choose to exercise any, all, or none of these options in its sole discretion. The 19C BARDA Contract includes: three separate IV
BDS  Options,  each  providing  for  the  bulk  drug  substance  equivalent  of  64,000  courses  of  IV  TPOXX®;  and  three  separate  IV  FDP  Options,  each
providing  for  64,000  courses  of  final  drug  product  of  IV  TPOXX®.  BARDA  has  the  sole  discretion  as  to  whether  to  simultaneously  exercise  IV  BDS
Options and IV FDP Options, or whether to exercise options at different points in time (or alternatively, to only exercise the IV BDS Option but not the IV
FDP  Option).  If  BARDA  decides  to  only  exercise  IV  BDS  Options,  then  the  Company  would  receive  payments  up  to  $30.7  million;  alternatively,  if
BARDA decides to exercise both IV BDS Options and IV FDP Options, then the Company would receive payments up to $76.8 million. For each set of
options relating to a specific group of courses (for instance, the IV BDS and IV FDP options that reference the same 64,000 courses), BARDA has the
option to independently purchase IV BDS or IV FDP.

Revenues in connection with the 19C BARDA Contract are recognized either over time or at a point in time. Performance obligations related to product
delivery generate revenue at a point in time. Revenue from other performance obligations under the 19C BARDA Contract are recognized over time using
an input method using costs incurred to date relative to total estimated costs at completion. For the years ended December 31, 2020 and 2019, the Company
recognized revenues of $7.5 million and $7.4 million, respectively, on an over time basis. In contrast, revenue recognized for product delivery and therefore
at a point in time for the years ended December 31, 2020 and 2019, was $112.6 million and $11.1 million, respectively. 

2011 BARDA Contract

On May 13, 2011, the Company signed a contract with BARDA pursuant to which BARDA agreed to buy from the Company 1.7 million courses of oral
TPOXX®. Additionally, the Company agreed to contribute to BARDA 300,000 courses at no additional cost to BARDA.

The contract with BARDA (as amended, modified, or supplemented from time to time the "2011 BARDA Contract") includes a base contract, as modified,
("2011 Base Contract") as well as options. The 2011 Base Contract specifies approximately $508.4 million of payments (including exercised options), of
which,  as  of  December  31,  2020,  $459.8  million  has  been  received  by  the  Company  for  the  manufacture  and  delivery  of  1.7  million  courses  of  oral
TPOXX® and $45.6 million has been received for certain reimbursements in connection with development and supportive activities. Approximately $3.0
million remains eligible to be received in the future for reimbursements of development and supportive activities.

For courses of oral TPOXX® that have been physically delivered to the Strategic Stockpile under the 2011 BARDA Contract, there are product
replacement obligations, including: (i) a product replacement obligation in the event that the final version of oral TPOXX® approved by the FDA was
different from any courses of oral TPOXX® that had been delivered to the Strategic Stockpile (the “FDA Approval Replacement Obligation”); (ii) a
product replacement obligation, at no cost to BARDA, in the event that oral TPOXX® is recalled or deemed to be recalled for any reason; and (iii) a
product replacement obligation in the event that oral TPOXX® does not meet any specified label claims. On July 13, 2018, the FDA approved oral
TPOXX® for the treatment of smallpox and there is no difference between the approved product and courses in the Strategic Stockpile. As such, the
possibility of the FDA Approval Replacement Obligation resulting in any future replacements of product within the Strategic Stockpile is remote.

The 2011 BARDA Contract includes options. On July 30, 2018, the 2011  BARDA  Contract  was  modified  and  BARDA  exercised  its  option  relating  to
FDA approval of the aforementioned 84-month expiry for oral TPOXX® for which the Company was paid $50.0 million in August 2018. With the option
exercise, the 2011 BARDA Contract was modified so that the 2011 Base Contract increased by $50.0 million. Remaining options, if all were exercised by
BARDA, would result in aggregate payments to the Company of $72.7 million, including up to $58.3 million of funding for development and supportive
activities such as work on a post-exposure prophylaxis ("PEP") indication for TPOXX® and/or $14.4 million of funding for production-related activities
related to warm-base manufacturing. BARDA may choose, in its sole discretion not to exercise any or all of the unexercised options. In 2015,  BARDA
exercised two  options  related  to  extending  the  indication  of  the  drug  to  the  geriatric  and  pediatric  populations.  The  stated  value  of  those  exercises  was
immaterial.

The 2011 BARDA Contract expires in December 2024.

As described in Note 2, cash inflows related to delivery of courses under the 2011 BARDA Contract had been recorded as deferred revenue prior to FDA
approval of oral TPOXX®, which occurred in the third quarter 2018. The deferral was due to the constraint on the consideration received related to the
FDA Approval Replacement Obligation. During the third quarter 2018, the constraint was satisfied with FDA approval of oral TPOXX®. As such, $375.6
million  associated  with  cash  consideration  received  in  prior  periods  under  the  2011  BARDA  Contract  was  recognized  as  revenue  for  the  year  ended
December 31, 2018. Separately, as discussed above, $90.9 million of revenues were recognized in the third quarter of 2018 in connection with a $40.9
million holdback payment (under the 2011 BARDA Contract) and a $50.0 million payment for achieving 84-month expiry for oral TPOXX® (under the
2011  BARDA  Contract).  Direct  costs  incurred  by  the  Company  to  manufacture  and  fulfill  the  delivery  of  courses  had  also  been  deferred.  As  of
December 31, 2017, deferred direct costs under the 2011 BARDA Contract were approximately $96.5 million. In connection with the FDA approval of oral
TPOXX®, all related deferred costs were recognized in the consolidated statement of operations during the third quarter of 2018.

Revenues in connection with the 2011 BARDA Contract are recognized either over time or at a point in time. Performance obligations related to product
delivery generate revenue at a point in time. Remaining performance obligations under the 2011 BARDA Contract generate revenue over time. For the
years  ended  December  31,  2020  and 2019,  the  Company  recognized  revenue  of  $0.2  million  and  $0.3  million,  respectively,  on  an  over  time  basis.  In
contrast, revenue recognized for product delivery and supportive services and therefore at a point in time for the years ended December 31, 2020 and 2019,
were $0.4 million and $0.1 million, respectively.

International Procurement Contracts
On January 13, 2021, the Public Health Agency of Canada ("PHAC") awarded a contract to Meridian Medical Technologies, Inc. (“Meridian,” a Pfizer
Company) (the “Contract”) for the purchase of up to approximately $33 million of oral TPOXX® (tecovirimat) within five years. The Contract specifies
firm  commitments  for  the  purchase  of  approximately  $3.4  million  of  oral  TPOXX®  to  occur  by  March  31,  2021  and  a  cumulative  purchase
of approximately $17 million of oral TPOXX® by March 31, 2023; the remaining courses under the Contract are targeted for delivery after March 31, 2023
and are subject to option exercise by PHAC. To date, SIGA has not finalized any deliveries yet in connection with this contract.

On April 3, 2020, the  Company  announced  that  the  Canadian  Department  of  National  Defence  (“CDND”)  awarded  a  contract  (the  "Canadian  Military
Contract")  to  Meridian,  pursuant  to  which  the  CDND  will  purchase  up  to  approximately  $14  million  of  oral  TPOXX®  over  four  years.  In  the  second
quarter 2020, CDND purchased $2.3 million of oral TPOXX®. The remaining purchases are at the option of the CDND, and are expected to occur after
regulatory approval of oral TPOXX® in Canada. Meridian is the CDND's counterparty under the Canadian Military Contract, and SIGA is responsible for
manufacture and delivery of any oral TPOXX® purchased thereunder.

The PHAC and CDND contract awards were both coordinated between SIGA and Meridian under the international promotion agreement, as amended (the
"International Promotion Agreement") that was entered into by the parties on June 3, 2019.

Under the terms of the International Promotion Agreement, Meridian was granted exclusive rights to market, advertise, promote, offer for sale, or sell oral
TPOXX® in a field of use specified in the International Promotion Agreement in all geographic regions except for the United States (the “Territory”), and
Meridian has agreed not to commercialize any competing product, as defined in the International Promotion Agreement, in the specified field of use in the
Territory. SIGA will retain ownership, intellectual property, distribution and supply rights and regulatory responsibilities in connection with TPOXX®, and,
in the United States market, will also retain sales and marketing rights with respect to oral TPOXX®. SIGA’s consent shall be required for the entry into
any sales arrangement pursuant to the International Promotion Agreement.

The  fee  Meridian  retains  pursuant  to  the  International  Promotion  Agreement  will  be  a  specified  percentage  of  the  collected  proceeds  of  sales  of  oral
TPOXX® net of certain expenses, for years in which customer invoiced amounts net of such expenses are less than or equal to a specified threshold, and a
higher specified percentage of such collected net proceeds for years in which such net invoiced amounts exceed the specified threshold.

Revenue  in  connection  with  international  procurement  contracts  for  the  delivery  of  product  are  recognized  at  a  point  in  time.  During  the  year  ended
December 31, 2020, the Company recognized $2.3 million of revenue for delivery to CDND. 

Research Agreements and Grants
The Company has an R&D program for IV TPOXX®. This program is funded by the 19C BARDA Contract and a separate development contract with
BARDA  ("IV  Formulation  R&D  Contract").  The  IV  Formulation  R&D  Contract  has  a  period  of  performance  that  terminates  in  February  2024.  As  of
December  31,  2020,  the  IV  Formulation  R&D  Contract  provides  for  future  aggregate  research  and  development  funding  of  up  to  approximately  $2.1
million.

Revenues in connection with the IV Formulation R&D Contract are recognized over time. For the years ended December 31, 2020 and 2019, the Company
recognized revenue of $1.4 million and $7.5 million, respectively, under this contract. During the year ended December 31, 2019, the Company completed
its negotiation with representatives of the U.S. Government for a change in the application of certain reimbursement rates in the contract. The change in the
application of those reimbursement rates increased the overall transaction price of the IV Formulation R&D Contract, but did not change the estimate of
costs to complete under the input method calculation. As a result, the Company accounted for this as a change in the transaction price and recognized a
cumulative catch-up adjustment to revenue of approximately $3.3 million representing the impact of the change in the application of those reimbursement
rates from January 2016 through March 2019.

In July 2019, the Company was awarded a multi-year research contract valued at a total of $19.5 million, with an initial award of $12.4 million, from the
Department of Defense ("DoD") to support work in pursuit of a potential label expansion for oral TPOXX® that would include post-exposure prophylaxis
("PEP")  of  smallpox  (such  work  known  as  the  "PEP  Label  Expansion  Program"  and  the  contract  referred  to  as  the  "PEP  Label  Expansion  R&D
Contract"). In May 2020, the DoD increased the scope and the contract value to a total of $26 million with current available funding of $23 million. As of
December  31,  2020,  the  PEP  Label  Expansion  R&D  Contract  provides  for  future  aggregate  research  and  development  funding  under  the  award,  as
modified, of up to approximately $22.4 million. The period of performance for this contract, as modified, terminates on July 31, 2025. For the years ended
December  31,  2020  and  2019,  the  Company,  under  the  PEP  Label  Expansion  R&D  Contract,  recognized  revenue  of  $0.3  million  and  $0.3  million,
respectively, on an over time basis.

Contracts and grants include, among other things, options that may or may not be exercised at the U.S. Government’s discretion. Moreover, contracts and
grants contain customary terms and conditions including the U.S. Government’s right to terminate or restructure a contract or grant for convenience at any
time. As such, the Company may not be eligible to receive all available funds.

4. Sale of Priority Review Voucher

Concurrent with the approval of oral TPOXX®, the FDA granted the Company's request for a Priority Review Voucher (“PRV”). A PRV is a voucher that
may be used to obtain an accelerated FDA review of a product candidate. On October 31, 2018 the Company sold its PRV for cash consideration of $80
million which was recognized as other income.

8. Debt

On March 13, 2020, the Company voluntarily prepaid the Loan Agreement in an approximate aggregate amount of $87.2 million. The prepayment was
made from restricted cash, including $80.0 million in respect of outstanding principal of the Term Loan, $4.0 million that was payable upon the repayment
of the Loan Agreement, approximately $1.2 million of accrued interest, and a prepayment premium amount of approximately $1.9 million. The prepayment
was  made  upon  the  Company  and  the  Lender  agreeing  to  and  entering  into  customary  mutual  releases  reflecting  that,  subject  to  such  prepayment  in
accordance with the terms of the Loan Agreement, all of the obligations under the Loan Agreement were released, discharged and satisfied in full. Upon
such prepayment and release, the Loan Agreement was terminated. For the year ended  December 31, 2020, the Company recognized approximately $5.0
million of a loss on the extinguishment of the Term Loan related to the remaining unamortized discount and the prepayment premium.

On September  2,  2016,  the  Company  entered  into  a  loan  and  security  agreement  (as  amended  from  time  to  time,  the  “Loan  Agreement”)  with  OCM
Strategic Credit SIGTEC Holdings, LLC (“Lender”), pursuant to which the Company received $80.0 million (the "Term Loan") (less fees and other items)
on November  16,  2016  having  satisfied  certain  pre-conditions.  Such  $80.0  million  had  been  placed  in  an  escrow  account  on  September  30,  2016  (the
“Escrow Funding Date”). Prior to the Escrow Release Date ( November 16, 2016), the Company did not have access to, or any ownership interest in, the
escrow account. Until the Escrow Release Date occurred, the Company did not have an obligation to make any payments under the Loan Agreement, no
security was granted under the Loan Agreement and no affirmative or negative covenants or events of default were effective under the Loan Agreement.
Amounts were held in the escrow account until the satisfaction of certain conditions including the closing of the Rights Offering on November 16, 2016. As
part of the satisfaction of a litigation claim, funds were released from the escrow account (the date on which such transfer occurred, the “Escrow Release
Date”). Interest on the Term Loan was at a per annum rate equal to the Adjusted LIBOR rate plus 11.5%, subject to adjustments as set forth in the Loan
Agreement.

The Term Loan had a maturity date on the earliest to occur of (i) the four-year anniversary of the Escrow Release Date, and (ii) the acceleration of certain
obligations pursuant to the Loan Agreement.

Through  the  three  and  one-half  year  anniversary  (  May  17,  2020)  of  the  Escrow  Release  Date,  any  prepayment  of  the  Term  Loan  was  subject  to  a
makewhole  provision  in  which  interest  payments  related  to  the  prepaid  amount  were  due  (subject  to  a  discount  of  treasury  rate  plus  0.50%).  Upon
repayment  of  the  Term  Loan,  an  additional  $4.0  million  payment  was  required.  Such  payment  had  been  accreting  to  the  Term  Loan  balance  since  the
Escrow Release Date.

In  connection  with  the  issuance  of  the  Loan  Agreement,  the  Company  incurred  $8.2  million  of  costs  (including  interest  on  amounts  held  in  the  escrow
account  between  September  30,  2016  and  November  15,  2016).  Furthermore,  an  additional  $4.0  million  was  payable  upon  repayment  of  Term  Loan
principal. As part of the Company's entry into the Loan Agreement, the Company issued the Warrant (see Note 10) with a fair market value of $5.8 million.
The fair value of the Warrant, as well as costs related to the Term Loan issuance, were recorded as deductions to the Term Loan balance on the Balance
Sheet. These amounts were being amortized on a straight-line basis over the life of the related Term Loan. The Company compared the amortization under
the effective interest method with the straight-line basis and determined the results were not materially different.

9. Per Share Data

The  Company  computes,  presents  and  discloses  earnings  per  share  in  accordance  with  the  authoritative  guidance  which  specifies  the  computation,
presentation and disclosure requirements for earnings per share of entities with publicly held common stock or potential common stock. The objective of
basic EPS is to measure the performance of an entity over the reporting period by dividing income (loss) by the weighted average shares outstanding. The
objective of diluted EPS is consistent with that of basic EPS, except that it also gives effect to all potentially dilutive common shares outstanding during the
period.

The following is a reconciliation of the basic and diluted (loss) earnings per share computation:

Net income (loss) for basic earnings per share
Less: Change in fair value of warrants
Net income (loss), adjusted for change in fair value of warrants for
diluted earnings per share
Weighted-average shares
Effect of potential common shares
Weighted-average shares: diluted

For  the  year  ended  December  31,  2020,  diluted  shares  outstanding  include  the  dilutive  effect  of  in-the-money  options,  unvested  restricted  stock  and
unreleased restricted stock units. The dilutive effect of options is calculated based on the average share price for each fiscal period using the treasury stock
method. Under the treasury stock method, the amount the employee must pay for exercising stock options, the average amount of compensation cost for
future service that the Company has not yet recognized, and the amount of tax benefits that would be recorded in additional paid-in capital when the award
becomes deductible, are collectively assumed to be used to repurchase shares. Warrants were presumed to be cash-settled and therefore excluded from the
diluted earnings per share calculations for the year ended  December 31, 2020 because the net effect of their inclusion, including the elimination of the
impact  in  the  operating  results  of  the  change  in  fair  value  of  the  warrants,  would  have  been  anti-dilutive.  For  the  year  ended  December  31,  2020,  the
weighted average number of shares under the warrant excluded from the calculation of diluted earnings per share was 1,124,585.

10. Financial Instruments

2016 Warrant
On September 2, 2016, in connection with the entry into the Loan Agreement (see Note 8 for additional information), the Company issued a warrant (the
“Warrant”) to the Lender to purchase a number of shares of the Company’s common stock equal to $4.0 million divided by the lower of (i) $2.29 per share
and (ii) the subscription price paid in connection with the Rights Offering (as defined in Note 11). The subscription price paid was $1.50 in connection with
the Rights Offering; accordingly, the exercise price of the Warrant was set at $1.50 per share, and there were 2.7 million shares underlying the Warrant.
During  the  year  ended  December  31,  2020,  0.5  million  shares  on  the  warrant  were  exercised.  Subsequent  to  partial  exercises  of  the  Warrant,  there  are
approximately 1.0 million shares underlying the Warrant as of December 31, 2020. The Warrant provides for weighted average anti-dilution protection and
is exercisable in whole or in part for ten (10) years from the date of issuance.

The Company accounted for the Warrant in accordance with the authoritative guidance which requires that free-standing derivative financial instruments
with certain anti-dilution and cash settlement features be classified as assets or liabilities at the time of the transaction, and recorded at their fair value. Any
changes in the fair value of the derivative instruments are reported in earnings or loss as long as the derivative contracts are classified as assets or liabilities.
Accordingly, the Company classified the Warrant as a liability and reports its change in fair value in the consolidated statement of operations.

On September 2, 2016, the issuance date of the Warrant, the fair value of the liability-classified Warrant was $5.8 million. The Company applied a Monte
Carlo Simulation-model to calculate the fair value of the Warrant and compared the Monte Carlo simulation model calculation to a Black-Scholes model
calculation as of December 31, 2016. These models generated substantially equivalent fair values for the Warrant. As such, the Company utilized a Black-
Scholes model at December 31, 2020 and 2019 to determine the fair value of the Warrant.

As of December 31, 2020, the fair value of the Warrant was $6.6 million. A Black Scholes model was applied to calculate the fair value of the Warrant
using the following assumptions: risk free interest rate of 0.46%; no dividend yield; an expected life of 5.7 years; and a volatility factor of 80%.

As of December 31, 2019, the fair value of the Warrant was $6.1 million. A Black Scholes model was applied to calculate the fair value of the Warrant
using the following assumptions: risk free interest rate of 1.81%; no dividend yield; an expected life of 6.7 years; and a volatility factor of 70%.

At December 31, 2020, pursuant to the Warrant agreement, there were no conditions under which current assets would have been required to satisfy the
Warrant obligation.

11. Stockholders’ Equity

On December 31, 2020, the Company’s authorized share capital consisted of 620,000,000 shares, of which 600,000,000 are designated common shares and
20,000,000 are designated preferred shares. The Company’s Board of Directors is authorized to issue preferred shares in series with rights, privileges and
qualifications of each series determined by the Board. As of December 31, 2020 and 2019, no preferred shares were outstanding or issued.

On  March  5,  2020,  the  Company  announced  that  the  Board  of  Directors  had  authorized  a  share  repurchase  program  under  which  the  Company  may
repurchase,  from  time  to  time,  up  to  an  aggregate  of  $50  million  of  the  Company's  common  stock  through  December 31, 2021. The  timing  and  actual
number  of  shares  repurchased  will  depend  on  a  variety  of  factors,  including:  exercise  of  procurement  options  under  government  contracts;  alternative
opportunities for strategic uses of cash; the stock price of the Company’s common stock; market conditions; and other corporate liquidity requirements and
priorities. Repurchases under the program may be made from time to time at the Company’s discretion in open market transactions, through block trades, in
privately negotiated transactions, and pursuant to any trading plan that may be adopted by the Company’s management in accordance with Rule 10b5-1 of
the Securities Exchange Act of 1934, as amended, or otherwise. During the year ended December 31, 2020, the Company repurchased 4.6 million shares of
common stock, respectively, for approximately $28.5 million.

12. Stock Compensation Plans

The Company’s 2010 Stock Incentive Plan (the “2010 Plan”) was initially adopted in May 2010. The 2010 Plan provided for the issuance of stock options,
restricted stock and unrestricted stock with respect to an aggregate of 2,000,000 shares of the Company’s common stock to employees, consultants and
outside directors of the Company. On May 17, 2011, the 2010 Plan was amended to provide for the issuance of restricted stock units (“RSUs”) and on
February 2, 2012, the 2010 Plan was amended to provide for the issuance of stock-settled stock appreciation rights ("SSARs"). Effective April 25, 2012 and
May  23,  2017,  the  2010  Plan  was  amended  to  increase  the  maximum  number  of  shares  of  common  stock  available  for  issuance  to  an  aggregate  of
4,500,000  shares  and  8,500,000  shares,  respectively.  The  vesting  period  for  awards  granted  under  the  2010  Plan  is  determined  by  the  Compensation
Committee of the Board of Directors. The Compensation Committee also determines the expiration date of each equity award; however, stock options  may
not be exercisable more than ten years after the date of grant as the maximum term of equity awards issued under the 2010 Plan is ten years.

For the years ended December 31, 2020, 2019 and 2018, the Company recorded stock-based compensation expense, including stock options and RSUs, of
approximately $1.4 million, $2.1 million and $2.3 million, respectively.

Stock Options
Stock option awards provide holders the right to purchase shares of Common Stock at prices determined by the Compensation Committee, at the time of
grant, and must have an exercise price equal to or in excess of the fair market value of the Company’s common stock at the date of grant.

The fair value of options granted is estimated at the date of grant. Expected volatility has been estimated using a combination of the historical volatility of
the Company's common stock and the historical volatility of a group of comparable companies’ common stock, both using historical periods equivalent to
the options’ expected lives. The expected dividend yield assumption is based on the Company’s intent not to issue a dividend in the foreseeable future. The
risk-free  interest  rate  assumption  is  based  upon  observed  interest  rates  for  securities  with  maturities  approximating  the  options’  expected  lives.  The
expected  life  was  estimated  based  on  historical  experience  and  expectation  of  employee  exercise  behavior  in  the  future  giving  consideration  to  the
contractual terms of the award.

The  recognition  of  a  valuation  allowance  for  deferred  taxes  requires  management  to  make  estimates  and  judgments  about  the  Company’s  future
profitability which is inherently uncertain. The Company assesses all available positive and negative evidence to determine if its existing deferred tax
assets  are  realizable  on  a  more-likely-than-not  basis.  In  making  such  assessment,  the  Company  considered  the  reversal  of  existing  taxable  temporary
differences, projected future taxable income, tax planning strategies and recent financial operating results. The ultimate realization of a deferred tax asset
is ultimately dependent on the Company's generation of sufficient taxable income within the available net operating loss carryback and/or carryforward
periods to utilize the deductible temporary differences. As of December 31, 2020 and 2019, the Company has a valuation allowance on certain state and
local  net  operating  losses  which  the  Company  determined  were  not  realizable  on  a  more-likely-than-not  basis.  The  Company’s  valuation  allowance
decreased by $24,873 during the year ended December 31, 2020.

For the year ended December 31, 2020, the Company’s effective tax rate differs from the statutory rate of 21% primarily as a result of non-deductible
executive compensation under IRC Section 162(m), state and local taxes, and a non-taxable adjustment for the fair market value of the Warrant. For the
year ended December 31, 2019, the Company's effective tax rate differs from the statutory rate of 21% primarily as a result of non-deductible executive
compensation under IRC Section 162(m) and a non-taxable adjustment for the fair market value of the Warrant.

Included in the balance of unrecognized tax benefits as of December 31, 2020, are potential benefits of $5.6 million that, if recognized, would affect the
effective tax rate. For the years ended  December 31, 2020 and December 31, 2019, interest and penalties on unrecognized tax benefits were $65,000 and
$38,000  respectively.  There  are  no  uncertain  tax  positions  for  which  it  is  reasonably  possible  that  the  total  amounts  of  unrecognized  benefits  will
significantly increase or decrease within twelve months from December 31, 2020.

The  Company  files  federal  income  tax  returns  and  income  tax  returns  in  various  state  and  local  tax  jurisdictions.  The  federal  tax  years  open  to
examination are 2017 to 2020. The Company's state and local tax years open to examination are 2016-2020.

14. Commitments and Contingencies

Operating lease commitments
The Company leases its Corvallis, Oregon, facilities and office space under an operating lease which was signed on November 3, 2017 and commenced on
January 1, 2018. This lease expires December 31, 2021. The Company had a lease for the same location prior to this lease. On May 26, 2017 the Company
and M&F Incorporated entered into a ten-year office lease agreement (the “New HQ Lease”), pursuant to which the Company agreed to lease 3,200 square
feet at 31 East 62nd Street, New York, New York. The Company is utilizing premises leased under the New HQ Lease as its corporate headquarters. The
Company has no leases that qualify as finance leases.

Operating lease costs totaled $0.7 million and $0.6 million for the years ended December 31, 2020 and 2019, respectively. Cash paid for amounts included
in the measurement of lease liabilities from operating cash flows was $0.6 million and $0.6 million for the years ended December 31, 2020 and 2019,
respectively. As of December 31, 2020, the weighted-average remaining lease term of the Company’s operating leases was 5.7 years while the weighted-
average discount rate was 4.53%.

portion included in accrued expenses.

Legal Proceedings

From  time  to  time,  we  may be  involved  in  a  variety  of  claims,  suits,  investigations  and  proceedings  arising  from  the  ordinary  course  of  our  business,
collections  claims,  breach  of  contract  claims,  labor  and  employment  claims,  tax  and  other  matters.  Although  such  claims,  suits,  investigations  and
proceedings are inherently uncertain and their results cannot be predicted with certainty, we believe that the resolution of such current pending matters, if
any, will not have a material adverse effect on our business, consolidated financial position, results of operations or cash flow. Regardless of the outcome,
litigation can have an adverse impact on us because of legal costs, diversion of management resources and other factors.

Purchase Commitments

In the course of our business, the Company regularly enters into agreements with third party organizations to provide contract manufacturing services and
research  and  development  services.  Under  these  agreements,  the  Company  issues  purchase  orders  which  obligate  the  Company  to  pay  a  specified  price
when agreed-upon services are performed. Commitments under the purchase orders do not exceed our planned commercial and research and development
needs. As of December 31, 2020, the Company has approximately $12.5 million of purchase commitments associated with manufacturing obligations.

15. Related Party Transactions

Board of Directors and Outside Counsel
A member of the Company’s Board of Directors is a member of the Company’s outside counsel. During the years ended December 31, 2020, 2019 and
2018,  the  Company  incurred  expenses  of  approximately  $478,000,  $468,000  and  $450,000,  respectively,  related  to  services  provided  by  the  outside
counsel. On December 31, 2020 the Company’s outstanding payables and accrued expenses included a $78,000 liability to the outside counsel.

Board of Directors-Consulting Agreement
On  October  13,  2018,  the  Company,  entered  into  a  consulting  agreement  with  Dr.  Eric  A.  Rose,  a  member,  and  former  Executive  Chairman,  of  the
Company’s Board of Directors. Under the agreement, the consulting services included assisting the Company on expanded indications for TPOXX® and
other business development opportunities as requested by the Company. The term of the agreement expired on October 13, 2020 and the agreement has not

$157,000 related to services under this agreement. As of December 31, 2020, the Company’s outstanding payables and accrued expenses included a $7,000
liability associated with this agreement.

Real Estate Leases
On May 26, 2017 the Company and M&F Incorporated entered into the New HQ Lease, pursuant to which the Company agreed to lease 3,200 square feet
at 31  East  62nd  Street,  New  York,  New  York.  The  Company  is  utilizing  premises  leased  under  the  New  HQ  Lease  as  its  corporate  headquarters.  The
Company's rental obligations consist of a fixed rent of $25,333, per month in the first sixty-three months of the term, subject to a rent abatement for the
first  six  months  of  the  term.  From  the  first  day  of  the  sixty-fourth  month  of  the  term  through  the  expiration  or  earlier  termination  of  the  lease,  the
Company's rental obligations consist of a fixed rent of $29,333 per month. In addition to the fixed rent, the Company will pay a facility fee in consideration
of the landlord making available certain ancillary services, commencing on the first anniversary of entry into the lease. The facility fee will be $3,333 per
month for the second year of the term and increase by five percent each year thereafter, to $4,925 per month in the final year of the term.

On July 31, 2017, the Company and M&F, entered into a Termination of Sublease Agreement (the “Old HQ Sublease Termination Agreement”), pursuant
to  which  the  Company  and  M&F  agreed  to  terminate  the  sublease  dated  January 9, 2013 for  6,676  square  feet  of  rental  square  footage  located  at  660
Madison Avenue, Suite 1700, New York, New York (such sublease being the “Old HQ Sublease” and the location being the “Old HQ”).

Effectiveness of the Old HQ Sublease Termination Agreement was conditioned upon the commencement of a sublease for the Old HQ between M&F and a
new  subtenant  (the  “Replacement  M&F  Sublease”),  which  occurred  on  August  2,  2017.  The  Old  HQ  Sublease  Termination  Agreement  obligates  the
Company to pay, on a monthly basis, an amount equal to the discrepancy (the “Rent Discrepancy”) between the sum of fixed rent and Additional Rent (as
defined  below)  under  the  Old  HQ  Overlease  (as  defined  below)  and  the  sum  of  fixed  rent  and  Additional  Rent  under  the  Replacement  M&F  Sublease.
Under the Old HQ Sublease Termination Agreement, the Company and M&F release each other from any liability under the Old HQ Sublease.

Under  the  Old  HQ  Sublease,  the  Company  was  obligated  to  pay  fixed  rent  of  approximately  $60,000  per  month  until  August  2018  and  approximately
$63,400  per  month  thereafter  until  the  Old  HQ  Sublease  expiration  date  in    September  2020.  Additionally,  the  Company  was  obligated  to  pay  certain
operating expenses and taxes (“Additional Rent”), such Additional Rent being specified in the overlease between M&F and the landlord at 660 Madison
Avenue (the “Old HQ Overlease”).

Under the Replacement M&F Sublease, the subtenant’s rental obligations were excused for the first two (2) months of the lease term (“Rent Concession
Period”). Thereafter, the subtenant was obligated to pay fixed rent of $36,996 per month for the first twelve (12) months, and was obligated to pay $37,831
per  month  for  the  next  12  months,  and  $38,665  per  month  until  the  scheduled  expiration  of  the  Replacement  M&F  Sublease  in  September,  2020.  In
addition to fixed rent, the subtenant was also obligated to pay, pursuant to the Replacement M&F Sublease, a portion of the Additional Rent specified in the
Old HQ Overlease.

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

None.

Item 9A. Controls and Procedures

Evaluation of Disclosure Controls and Procedures

Our management, with the participation of our Chief Executive Officer and Chief Financial Officer, evaluated the effectiveness of our disclosure
controls  and  procedures  as  of  December  31,  2020  in  accordance  with  the  framework  on  Internal  Control-Integrated  Framework  (2013)  issued  by  the
Committee of Sponsoring Organizations of the Treadway Commission. The term “disclosure controls and procedures” is defined in Rules 13a-15(e) and
15d-15(e) under the Securities Exchange Act of 1934. Management recognizes that any disclosure controls and procedures no matter how well designed
and operated, can only provide reasonable assurance of achieving their objectives and management necessarily applies its judgment in evaluating the cost-
benefit relationship of possible controls and procedures.

Based  on  that  evaluation,  our  Chief  Executive  Officer  and  Chief  Financial  Officer  have  concluded  that  our  disclosure  controls  and  procedures

were effective as of December 31, 2020 at a reasonable level of assurance.

Changes in Internal Control over Financial Reporting

There have been no changes in our internal control over financial reporting during the quarter ended December 31, 2020 that materially affected,

or are reasonably likely to materially affect, our internal control over financial reporting.

Management’s Report on Internal Control over Financial Reporting

Management  is  responsible  for  establishing  and  maintaining  adequate  internal  control  over  financial  reporting,  as  such  term  is  defined  in  Rule
13a-15(f) or Rule 15d-15(f) of the Securities Exchange Act of 1934, as amended. Internal control over financial reporting is a process designed to provide
reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with
generally accepted accounting principles. Our internal control over financial reporting includes those policies and procedures that:

•

•

•

pertain  to  the  maintenance  of  records  that,  in  reasonable  detail,  accurately  and  fairly  reflect  the  transactions  and  disposition  of  the  Company’s
assets;

provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally
accepted  accounting  principles,  and  that  receipts  and  expenditures  of  the  Company  are  being  made  only  in  accordance  with  authorizations  of
management and the directors of the Company; and

provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use or disposition of the Company’s assets that
could have a material effect on the financial statements.

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

Our management conducted an evaluation of the effectiveness of our internal control over financial reporting as of December 31, 2020 using the
framework in Internal Control-Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission. Based
on  this  evaluation  using  the  COSO  criteria,  management  concluded  that  the  Company’s  internal  control  over  financial  reporting  was  effective  as  of
December 31, 2020.
