Overview
 
SIGA Technologies, Inc. is referred to throughout this report as “SIGA,” “the Company,” “we” or “us.”
 
We are a pharmaceutical company specializing in the development and commercialization of pharmaceutical solutions for some of the most lethal disease-causing pathogens in the world - smallpox, Ebola, dengue, Lassa fever and other dangerous viruses. Our business is to discover, develop, manufacture and successfully commercialize drugs to prevent and treat these high-priority threats. Our mission is to disarm dreaded viral diseases and create robust, modern biodefense countermeasures.
 
Commercial Product - ST-246®

Our lead product, ST-246, is an orally administered antiviral drug that targets orthopoxviruses. On May 13, 2011, we signed the BARDA Contract pursuant to which we agreed to deliver two million courses of ST-246 to the Strategic Stockpile. The five-year base contract award is worth approximately $435 million, and the BARDA Contract also includes various options to be exercised at BARDA’s discretion. As originally issued, the BARDA Contract included an option for the purchase of up to 12 million additional courses of ST-246; however, following a protest by a competitor of the Company, BARDA issued a contract modification on June 24, 2011 pursuant to which it deleted the option to purchase the additional courses. Under the BARDA Contract as modified, BARDA has agreed to buy from SIGA 1.7 million courses of ST-246. Additionally, SIGA will contribute to BARDA 300,000 courses manufactured using federal funds provided by the U.S. Department of Health and Human Services (“HHS”) under prior development contracts. The BARDA Contract as modified also contains options that will permit SIGA to continue its work on pediatric and geriatric versions of the drug as well as use of ST-246 for smallpox prophylaxis. As discussed in Item 3, “Legal Proceedings,” the amount of profits we are likely to retain pursuant to the BARDA Contract is dependent upon resolution of the pending dispute described in such section.

We believe ST-246 will be the first entirely new small-molecule drug delivered to the Strategic Stockpile under the Project

BioShield Act of 2004 (“Project BioShield”). The U.S. Food and Drug Administration (“FDA”) has designated ST-246 for “fast-track status,” creating a path for expedited FDA review and eventual regulatory approval.

ST-246 is a novel, patented drug that is easy to store, transport and administer. ST-246 inhibits vaccinia, cowpox, ectromelia (mousepox), monkeypox, rabbitpox, camelpox, and variola (smallpox) replication in cell culture and in various animal models, but not other unrelated viruses. There could be several uses for an effective smallpox antiviral drug: therapeutically, to reduce mortality and morbidity in those infected with the smallpox virus; prophylactically, to protect the non-immune who risk developing smallpox following virus exposure; and, lastly, as an adjunct to the smallpox vaccine in order to reduce the frequency of serious adverse events due to the live virus used for vaccination. We filed an Investigational New Drug (“IND”) application for ST-246 with FDA in November 2005. In June 2006, we successfully completed the first human clinical safety study of ST-246. The trial showed the drug to be well-tolerated in healthy human volunteers at all tested orally administered doses. In addition, data from blood level exposure was sufficient to support once-a-day dosing. The study was a double-blind, randomized, placebo controlled and ascending single dose study. In 2006, ST-246 became the first oral drug ever to demonstrate 100% protection against human smallpox virus in a primate trial conducted at the U.S. Centers for Disease Control and Prevention (“CDC”). Later in 2006, in two non-human primate trials the drug demonstrated 100% protection for animals injected with high doses of monkeypox virus. One study was sponsored by the National Institute of Allergy and Infectious Diseases (“NIAID”) at the National Institutes of Health (“NIH”). The second study was conducted by the U.S. Army Medical Research Institute of Infectious Diseases (“USAMRIID”) and was funded by the Department of Defense’s Threat Reduction Agency (“DTRA”). Also in late 2006, ST-246 received Orphan Drug designation for both the treatment and prevention of smallpox, and subsequently in September 2010, received Orphan Drug designation for the broader indication of treatment of orthopoxvirus infections (vaccinia, variola, monkeypox and cowpox). An additional Phase I clinical trial started in February 2007 was a 21-day, escalating, multiple-dose, Phase I safety, tolerability and pharmacokinetics study of ST-246 at three different dosages in healthy volunteers. The study was completed in December 2007, and the results indicated that the drug was safe and well tolerated at all tested doses. In August 2008, a Phase I study was performed at the Orlando Clinical Research Center in Orlando, Florida to compare ST-246 polymorph form I to form V. We submitted the final Clinical Study Report for that study to the FDA in May 2009. In December 2009, we completed a Phase II multiple dose clinical trial to evaluate the safety, tolerability and pharmacokinetics of ST-246 when administered as a single, daily oral dose for fourteen days. In that study, ST-246 was well tolerated and did not elicit any serious adverse events. More recently, in 2011, we completed three additional monkeypox efficacy studies in non-human primates to support dose selection, treatment after lesion onset and dose duration. The final reports on these studies have been submitted to FDA for review.

In December 2011, FDA convened an Advisory Committee to consider proposals for using a surrogate orthopoxvirus model in lieu of a reproducible and consistent variola model and to determine what elements of the “animal rule” constitute “enough” evidence for approval of a drug for the treatment of smallpox. The Advisory Committee’s recommendation confirmed that the monkeypox, rabbitpox and ectromelia models, especially in combination, could suitably provide appropriate evidence of efficacy for treatment of smallpox. Animal testing to date has proven ST-246 to be highly effective in all three of these models.
 
Product Candidates and Market Potential  

Dengue Antiviral: Dengue fever, dengue hemorrhagic fever, and dengue shock syndrome are caused by one of four serotypes of dengue virus of the genus Flavivirus. Dengue is considered by the World Health Organization to be the most important arthropod-borne viral disease with an estimated 50-100 million people infected with the virus each year. There is currently no approved antiviral or vaccine for the treatment or prevention of dengue-mediated disease. We currently have two drug series in the pre-clinical development stage, each with activity against all four serotypes of virus. Compounds from these series have recently shown efficacy in a murine model of disease and are undergoing optimization through medicinal chemistry.

Anti-Arenavirus Drug: Arenaviruses are hemorrhagic fever viruses that have been classified as Category A agents by CDC due to the great risk that they pose to public health and national safety. The hemorrhagic fever arenaviruses (Lassa virus in Africa and Junin, Machupo, Guanarito and Sabia viruses in South America) have no available FDA-approved treatment. In order to combat this threat, our scientists have identified one lead drug candidate, which has demonstrated significant antiviral activity in cell culture assays against Lassa fever virus. Lassa fever is an acute viral illness prevalent in West Africa with an estimated 100,000 to 300,000 infections. We have demonstrated therapeutic efficacy of our lead candidate against Lassa fever in several animal challenge studies. We also have programs against other hemorrhagic fever viruses, including Rift Valley Fever, Lymphocytic choriomeningitis virus and Ebola. We believe that the availability of hemorrhagic fever virus antiviral drugs will address national and global security needs by acting as a significant deterrent and defense against the use of arenaviruses as weapons of bioterrorism or biowarfare.
 
Broad Spectrum Antiviral: We continue research and development efforts aimed at developing a comprehensive biodefense against those microbial agents most likely to be deployed as biological weapons. A broad-spectrum antiviral would have great

utility against natural or intentional introduction of these agents into population centers, as well as provide a treatment option in areas where these pathogens are endemic. Screening for antivirals against specific CDC Category A and B pathogens, utilizing our high-throughput screening program, led to the identification of a unique collection of compounds with broad spectrum antiviral activity. Compounds with potent, non-toxic activity against a diversity of virus families are currently being characterized with respect to antiviral mechanism(s) of action. Our chemi-informatics tools are being employed to explore and determine structure-activity relationships within the lead compound series. To date, we have documented sub-micromolar activity of a broad spectrum antiviral candidate against viruses in the Poxviridae, Filoviridae, Bunyaviridae, Arenaviridae, Flaviviridae, Togaviridae, Retroviridae and Picornaviridae families. Lead series are being assessed with respect to the mechanism of antiviral action, formulated for testing in vivo, and administered by multiple routes and dosing regimens to those small animal species traditionally used for modeling the pathogenesis of Category A viruses.
 
Market for Biological Defense Programs
 
The market for biodefense countermeasures is sizeable and very active in light of awareness of the threat of global terror and biowarfare activity. The U.S. government is a lead source of worldwide biodefense spending. U.S. government spending on biodefense programs includes development funding awarded by NIAID, BARDA and the Department of Defense (“DoD”), and procurement of countermeasures by HHS, CDC and DoD. The U.S. government is the largest source of development and procurement funding for academic institutions and biotechnology companies conducting biodefense research or developing vaccines, anti-infectives and immunotherapies directed at potential agents of bioterror or biowarfare.
 
Project BioShield, which became law in 2004, authorizes the procurement of countermeasures for biological, chemical, radiological and nuclear attacks for the Strategic Stockpile, which is a national repository of medical assets and countermeasures designed to provide federal, state and local public health agencies with medical supplies needed to treat and protect those affected by terrorist attacks, natural disasters, industrial accidents and other public health emergencies. Project BioShield provided appropriations of $5.6 billion to be expended over ten years. The Pandemic and All-Hazards Preparedness Act (the “Preparedness Act”) established BARDA as the agency responsible for awarding procurement contracts for biomedical countermeasures and providing development funding for advanced research and development in the biodefense arena. The Preparedness Act supplements the funding available under Project BioShield for radiological, nuclear, chemical and biological countermeasures, and emerging infectious disease threats. Advanced development funding for BARDA is created by annual appropriations by Congress. Congress also appropriates annual funding for CDC for the procurement of medical assets and countermeasures for the Strategic Stockpile and for NIAID to conduct biodefense research. This appropriation funding supplements amounts available under Project BioShield.

In addition to the U.S. government, we believe that other potential additional markets for the sale of biodefense countermeasures include:

foreign governments, including both defense and public health agencies;

state and local governments, which we expect may be interested in these products to protect, among others, emergency responders, such as police, fire and emergency medical personnel;
 
non-governmental organizations and multinational companies, including transportation and security companies; and
 
healthcare providers, including hospitals and clinics.

Manufacturing

We use third parties known as Commercial Manufacturing Organizations (“CMOs”) for the procurement of commercial raw materials and supplies, and for the manufacturing of ST-246. All of our CMOs certify that the methods, facilities and controls used for manufacturing, processing, packaging and holding pharmaceuticals conform to current good manufacturing practices (cGMP), the standard set by FDA for manufacture of pharmaceuticals intended for human use.

Technology
 
Antiviral Technology: Two Approaches
 
We have two approaches to the discovery and development of new antiviral compounds: high-throughput screening (“HTS”) and rational drug design. For HTS, we use whole cell virus inhibition assays, pseudotype virus inhibition assays and validated target biochemical assays. We currently have an in-house library of 260,000 small molecule compounds that may be used for screening in these various assays. This strategy allows for both target-specific and target-neutral screening and identification

of novel antiviral compounds. Compounds are also screened for toxicity in various cell lines to develop a therapeutic index (“TI”), which is the ratio of the concentration at which the compound is toxic to 50% of the cells (CC50) and the concentration of compound required to inhibit 50% of the virus (EC50) (TI = CC50/EC50). Compounds with an acceptable TI are selected for chemical optimization and proceed into the antiviral drug development pipeline.
    
We use rational drug design to model structure-activity relationships and facilitate lead optimization of compounds of interest.
 
Collaborative Research Agreements
 
We obtain funding in the form of grants or contracts (individually, “Grant,” and collectively, “Grants”) from various agencies of the U.S. government to support our research and development activities. Since inception, we have recognized $47.5 million of revenue from Grants currently active or expired during the year. Currently, we have four active Grants with varying expiration dates through July 2016 that provide for potential future aggregate research and development funding for specific projects of approximately $25.3 million, as amended. This amount includes, among other things, options that may or may not be exercised at the U.S. government’s discretion. The Grants contain customary terms and conditions and include the U.S. government’s right to terminate or restructure a grant for convenience at any time. We have entered into the following collaborative research arrangements and contracts:
 
National Institutes of Health. The following Grants awarded by NIH were still active for 2011:
 
Smallpox antiviral drug development: In 2006, we were awarded Grants from NIH totaling approximately $21 million for the continued development of ST-246. In 2008, we were awarded a $55.1 million Grant from NIH to support the development of additional formulations and orthopox-related indications for ST-246. In 2008, we were awarded $20.0 million from NIH under an existing $16.5 million Grant. In August 2011, these Grants were restructured and transferred to BARDA so that $14.0 million was eligible to cover performance through February 2013.
    
In September 2009, we received a three-year, $3.0 million Phase II Grant from NIH to fund the continued development of ST-246 for the treatment of smallpox vaccine-related adverse events.

In total, as of December 31, 2011, approximately $13.0 million is available to us under the aforementioned funding opportunities.
 
Anti-arenavirus drug development: In August 2011, we received a 5-year Grant of $7.7 million from NIH to continue funding for the development of antiviral drugs for Lassa fever virus. As of December 31, 2011, there is $7.3 million available under this Grant.
 
Dengue antiviral drug development: In May 2011, we received a 5-year Grant of $6.5 million from NIH to continue funding for the development of antiviral drugs for dengue. As of December 31, 2011, there is $5.0 million available under this Grant.
 
Broad spectrum antiviral drug development: In September 2009, we were awarded a 2-year, $1.7 million Grant from NIAID to support the development of broad-spectrum, small-molecule inhibitors of bunyaviruses. The Grant was awarded under the American Recovery and Reinvestment Act of 2009 (the “Recovery Act”). This Grant concluded in August 2011; as of December 31, 2011, there are no remaining funds available for the development of the drug under this Grant.
    
Defense Threat Reduction Agency. In February 2010, we were awarded a $2.9 million Grant with options for up to $9.9 million from DTRA to support the pre-clinical development and IND filing of a broad spectrum antiviral drug candidate. This award concluded in April 2011; consequently, as of December 31, 2011, there are no remaining funds available under this Grant.

We receive cash payments from NIH for Grants on a monthly basis, as services are performed or goods are purchased. Our current Grants do not include milestone payments. The Grant agreements can be cancelled for non-performance and, if cancelled, we will not receive funds for additional future work under the agreements. .

Competition
 
The biotechnology and pharmaceutical industries are characterized by rapidly evolving technology and intense competition. Our competitors include most of the major pharmaceutical companies, each of which has financial, technical and marketing resources significantly greater than ours. In addition, biotechnology and other pharmaceutical competitors include, but are not limited to, Sanofi Pasteur SA (formerly Acambis), Bavarian Nordic AS, Chimerix Inc. and Emergent BioSolutions. 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.
 
Our biodefense product candidates face significant competition for U.S. 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 government procurement requirements, particularly requirements of the U.S. government with respect to biodefense products.
 
Human Resources and Research Facilities
 
As of February 1, 2012, we had 68 full-time employees. None of our employees is covered by a collective bargaining agreement, and we consider our employee relations to be good. Our research and development facilities are located in Corvallis, Oregon, where we lease approximately 32,800 square feet under a lease agreement signed in January 2007, as amended in May 2011, and which expires in December 2017.
 
Intellectual Property and Proprietary Rights
 
Our commercial success will depend in part on our ability to obtain and maintain patent protection for our proprietary technologies, drug targets and potential products and to effectively preserve our 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 has emerged to date. Accordingly, we cannot predict the type and extent of claims allowed in these patents.
 
We are exclusive owner of 8 U.S. patents. We are also exclusive owner of 1 U.S. provisional patent applications, 18 U.S. utility patent applications, 4 international PCT patent applications and 127 foreign patent applications.

We also rely upon trade secret protection for our 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 our trade secrets or that we can meaningfully protect our trade secrets.

FDA regulations require that patented drugs be sold under brand names that comply with various regulations. We must develop and make efforts to protect these brand names for each of our products in order to avoid product piracy and secure exclusive rights to these brand names. We may expend substantial funds in developing and securing rights to adequate brand names for our products. We currently have proprietary trademark rights in SIGA®, ST-246® 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. We consider securing adequate trademark rights to be important to our business.
 
Government Regulation
 
Regulatory Approval Process. Regulation by governmental authorities in the United States and other countries is a significant factor in the production 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 such product. Virtually all of our potential biopharmaceutical 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 FDA and similar health authorities in foreign countries. Various federal statutes and regulations also govern or influence the manufacturing, safety, labeling, storage, record keeping and marketing of such products. The process of obtaining these approvals and the subsequent compliance with appropriate federal and foreign statutes and regulations requires the expenditure of substantial resources.
 
In order to test clinically, produce and market products for diagnostic or therapeutic use, a company must comply with mandatory procedures and safety standards established by 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 IND application and receive clearance from 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

Table of Contents

produce the drug, as well as an in-depth discussion of the human clinical studies that are being proposed.

The pre-marketing clinical program required for approval by 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 FDA and others.
 
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 has 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 ten years. Upon completion of such clinical testing, a company typically submits a New Drug Application (“NDA”) to FDA that summarizes the results and observations of the drug during the clinical testing. Based on its review of the NDA, FDA will decide whether to approve the drug. 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.
 
FDA amended its regulations, effective June 30, 2002, to include the “animal rule” whereby certain new drug and biological products used to reduce or prevent the toxicity of chemical, biological, radiological, or nuclear agents not otherwise naturally present in circumstances that would permit the typical clinical testing regime may be approved 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. We anticipate that we will seek approval for therapeutic use of ST-246 using the animal rule.
 
Once the product is approved for sale, FDA regulations govern the production process 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 approval under limited circumstances. The Emergency Use Authorization 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. We have provided data to FDA to support an Emergency Use Authorization for ST-246 in the event of a smallpox attack.
 
Legislation and Regulation Related to Bioterrorism Counteragents and Pandemic Preparedness. Because some of 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 HHS to commit funds to countermeasure projects. Project BioShield provides alternative procedures under the Federal Acquisition Regulation, the general rubric for acquisition of material 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 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.

Under Project BioShield, the Secretary of HHS, with the concurrence of the Secretary of the Department of Homeland Security and upon the approval of the President, can contract to purchase unapproved countermeasures for the Strategic Stockpile in specified circumstances. 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 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 entirely, or in part, circumvent FDA approval for marketing, its use in this manner would likely be limited to rare circumstances. The Secretary of HHS concluded that ST-246 will qualify within eight years for approval by FDA for therapeutic use against smallpox prior to award of the BARDA Contract in May 2011.
 
Public Readiness and Emergency Preparedness Act. The Public Readiness and Emergency Preparedness Act, or 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.” 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 8 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 countermeasures.
 
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. Whether or not we obtain FDA approval for a product, we may have to obtain approval of a 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 may vary substantially, based upon the type, complexity and novelty of the pharmaceutical drug candidate, the specific requirements of that jurisdiction, and in some countries whether 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, have adopted biodefense-specific regulation akin to that available in the United States such as a procedure similar to the “animal rule” promulgated by FDA.
 
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 U.S. Government Contracts and Grants
 
We currently expect to derive substantially all of our foreseeable future revenue from sales of ST-246 under the BARDA Contract in addition to Grants from various agencies of the U.S. government. If BARDA demand for ST-246 is reduced, our business, financial condition and operating results could be materially harmed.

Our BARDA Contract does not necessarily increase the likelihood that we will secure future comparable contracts with the U.S. government. The success of our business and our operating results for the foreseeable future are substantially dependent on the terms of the ST-246 sales to the U.S. government, including price per course, the number and size of doses in a course and the timing of deliveries.

Furthermore, substantially all of our revenues for the years ended December 31, 2011, 2010 and 2009, respectively, were derived from Grants other than the BARDA Contract. Our current revenue is primarily derived from contract work being performed for NIH and BARDA under grants and one major contract scheduled to expire in February 2013. There can be no assurance that we will receive the revenue from the BARDA Contract in the time periods we anticipate or at all, or that we will be able to secure future Grants. Failure to receive such revenue or secure such Grants could have an adverse effect on our results of operations.
 
The pricing under our fixed-price government Grants is based on estimates of the time, resources and expenses required to perform these Grants. If our estimates are not accurate, we may not be able to earn an adequate return or may incur a loss under these Grants.

Our existing contract with BARDA for the supply of ST-246 includes fixed-price components. We expect that our future Grants with the U.S. government for ST-246 as well as Grants for biodefense product candidates that we successfully develop also may be fixed-price Grants. Under a fixed-price Grant, we are required to deliver our products at a fixed price regardless of the actual costs we incur and to absorb any cost in excess of the fixed price. Estimating costs that are related to performance in accordance with Grant specifications is difficult, particularly where the period of performance is over several years. Our failure to anticipate technical problems, estimate costs accurately or control costs during performance of a fixed-price Grant could reduce the profitability of a fixed-price Grant or cause a loss, which could in turn harm our operating results.

Our U.S. government Grants require ongoing funding decisions by the government. Reduced or discontinued funding of these Grants could cause our financial condition and operating results to suffer materially.

Our principal customer for ST-246 at the present time is the U.S. government. We anticipate that the U.S. government will also be the principal customer for any other biodefense product that we successfully develop. Over its lifetime, a U.S. government program, such as Project BioShield, may be implemented through the award of many different individual grants, contracts and subcontracts. The funding of some government programs 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 stringent budgetary constraints. Additionally, government-funded development grants and contracts typically consist of a base period of performance followed by successive option periods for performance of certain future activities. The value of these optional services, which options are exercisable in the sole discretion of the government, may constitute the majority of the total value of the underlying contract. If levels of government expenditures and authorizations for biodefense decrease or shift to programs in areas where we do not offer products or are not developing product candidates, our business, revenues and operating results may suffer.

Our future business may be harmed as a result of the government contracting process, which can be a competitive bidding process that may involve risks not present in the commercial contracting process.
 
We expect that a significant portion of the business that we will seek in the near future will be under government grants, contracts or subcontracts, which may be awarded through competitive bidding. Competitive bidding for government Grants presents a number of risks that are not typically present in the commercial contracting process, which may include:

the need to devote substantial time and attention of management and key employees to the preparation of bids and proposals for Grants that may not be awarded to us;
 
the need to accurately estimate the resources and cost structure that will be required to perform any Grant that we might be awarded;

the risk that the government will issue a request for proposal to which we would not be eligible to respond;
 
the risk that third parties may submit protests to our responses to requests for proposal that could result in delays or withdrawals of those requests for proposal; and
 
the expenses that we might incur and the delays that we might suffer if our competitors protest or challenge contract awards made to us pursuant to competitive bidding, and the risk that any such protest or challenge could result in the resubmission of bids based on modified specifications, or in termination, reduction or modification of the awarded Grant.

The U.S. government may choose to award future Grants for the supply of smallpox antivirus and other biodefense product candidates that we are developing to our competitors instead of to us. If we are unable to win particular Grants, we may not be able to operate in the market for products that are provided under those Grants for a number of years. For example, BARDA’s 2009 request for proposal with respect to acquisition of a smallpox antiviral was open to all qualifying small businesses for which we were determined not to qualify. If we are unable to consistently obtain new Grants over an extended period, or if we fail to anticipate all of the costs and resources that will be required to secure such Grants, our growth strategy and our business, financial condition, and operating results could be materially adversely affected.

The success of our business with the U.S. government depends on our compliance with regulations and obligations under our U.S. government Grants and various federal statutes and regulations.
 
Our business with the U.S. government is subject to specific procurement regulations and a variety of other legal compliance obligations. These laws and rules include those related to:

procurement integrity;
 
export control;
 
government security regulations;
 

11

Table of Contents

employment practices;
 
protection of the environment;
 
accuracy of records and the recording of costs; and
 
foreign corrupt practices.

In addition, before awarding us any Grant, the U.S. government could require that we respond satisfactorily to a request to substantiate our commercial viability and industrial capabilities. 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 Grant or relationship as a result of our failure to satisfy any of these obligations would have a negative impact on our operations and harm our reputation and ability to procure other government Grants in the future.
 
Unfavorable provisions in government Grants, some of which may be customary, may harm our future business, financial condition and potential operating results.
 
Government Grants customarily contain provisions that give the government substantial rights and remedies, many of which are not typically found in commercial contracts, including provisions that allow the government to:
 
terminate existing 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 Grants and related orders if funds for performance for any subsequent year become unavailable;
 
decline to exercise an option to renew a Grant;
 
exercise an option to purchase only the minimum amount specified in a Grant;
 
decline to exercise an option to purchase the maximum amount specified in a Grant;
 
claim rights to products, including intellectual property, developed under a Grant;
 
take actions that result in a longer development timeline than expected;
 
direct the course of a development program in a manner not chosen by the government contractor;
 
suspend or debar the contractor from doing business with the government or a specific government agency;
 
pursue criminal or civil remedies under the False Claims Act and False Statements Act; and
 
control or prohibit the export of products.

Generally, government Grants 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 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 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 Grants, including the BARDA Contract, could be terminated under these circumstances. Some government Grants permit the government the right to use, for or on behalf of the U.S. government, any technologies developed by the contractor under a government Grant. If we were to develop technology under a Grant with such a provision, we might not be able to prohibit third parties, including our competitors, from using that technology in providing products and services to the government.

Table of Contents

Political or social factors, including related litigation, may delay or impair our ability to market ST-246 and our 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 highly charged and unpredictable. Political or social pressures or 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 our products to market or limit pricing or purchases of our products, any of which would harm our business.

In addition, substantial delays or cancellations of purchases could result from protests or challenges from third parties. Furthermore, lawsuits brought against us by third parties such as activists, even if not successful, require us to spend time and money defending the related litigation. The need to address political and social issues may divert our management’s time and attention from other business concerns.

Additional lawsuits, publicity campaigns or other negative publicity may adversely affect the degree of market acceptance of, and thereby limit the demand for, ST-246 and our biodefense product candidates.  In such event, our ability to market and sell such products may be hindered and the commercial success of ST-246 and other products we develop will be harmed, thereby reducing our revenues.
 
Risks Related to Product Development
 
Our business depends significantly on our success in completing development and commercialization of drug candidates that are still under development. If we are unable to commercialize these drug candidates, or experience significant delays in doing so, our business will be materially harmed.
 
We have invested a substantial majority of our efforts and financial resources in the development of our drug candidates. Our ability to generate near-term revenue is particularly dependent on the success of our smallpox antiviral drug candidate ST-246. The commercial success of our drug candidates 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 and similar foreign regulatory authorities;
 
establishing commercial manufacturing processes of our own or arrangements on reasonable terms with 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, physicians, patients, healthcare payors and others in the medical community.

We expect to rely on FDA regulations known as the “animal rule” to obtain approval for certain 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 relatively new, and both we and the government have limited experience in the application of these rules to the drug candidates that we are developing. 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 harmed.

13

Table of Contents


We will not be able to commercialize our drug candidates if our pre-clinical development efforts are not successful, our clinical trials do not demonstrate safety or our clinical trials or animal studies do not demonstrate efficacy.
 
Before obtaining regulatory approval for the sale of our drug candidates, we must conduct extensive pre-clinical development, clinical trials to demonstrate the safety of our drug candidates and clinical or animal trials to demonstrate the efficacy of our drug candidates. Pre-clinical and clinical testing is expensive, difficult to design and implement, can take many years to complete and is 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 testing. 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 cost of 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; and
 
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.

We are in various stages of product development and there can be no assurance of successful commercialization.
 
In general, our research and development programs are at an early stage of development. To obtain FDA approval for our biodefense products, we will be required to obtain adequate proof of efficacy from at least one animal model and provide animal and human safety data. Our other products will be subject to the usual FDA regulatory requirements, which include a number of phases of testing in humans.
 
FDA has not approved any of our biopharmaceutical product candidates. Any drug candidate we develop will require significant additional research and development efforts, including extensive pre-clinical and clinical testing and regulatory approval, prior to commercial sale. We cannot be sure our approach to drug discovery will be effective or will result in the successful commercialization of any drug. We cannot predict with certainty whether any drug resulting from our research and development efforts will be commercially available within the next several years, or if they will be available at all.
 
Even if we receive initially positive pre-clinical or clinical results, such results do not mean that similar results will be obtained in later stages of drug development, such as additional pre-clinical testing or human clinical trials. All of our potential drug candidates are prone to the risks of failure inherent in pharmaceutical product development, including the possibility that none of our drug candidates will or can:

14

Table of Contents

 
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; and

achieve customer acceptance.

In addition, third parties may preclude us from marketing our drugs through enforcement of their proprietary rights that we are not aware of, or third parties may succeed in marketing equivalent or superior drug products. Our failure to develop safe, commercially viable drugs would have a material adverse effect on our business, financial condition and results of operations.
 
Risks Related to Commercialization
 
Our ability to grow our business depends significantly on our ability to achieve sales of ST-246 to customers other than the U.S. government.

An element of our business strategy is to sell ST-246 to customers other than the U.S. government. These potential customers include foreign governments and state and local governments, as well as 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. Some of these potential customers may wish to stockpile ST-246 in order to protect emergency responders such as police, fire and emergency medical personnel, as well as members of the general populace within their jurisdictions.

The market for sales of ST-246 to customers other than the U.S. government is undeveloped, and we may not be successful in generating meaningful sales of ST-246, if any, to these potential customers.

Governmental regulations may make it difficult for us to achieve significant sales of ST-246 to customers other than the U.S. government. For example, federal and foreign regulations usually require approval of the drug under generally applicable food and drug laws or waivers of such approval before these customers may procure the drug. Additionally, federal laws place various restrictions on the export of drugs that are not FDA-approved or that have potential biodefense-related uses. These restrictions are subject to change as global conditions change. These restrictions and other regulations on drug sales could limit our sales of ST-246 to foreign governments and other foreign customers. In addition, U.S. government demand for ST-246 may limit supplies of ST-246 available for sale to non-U.S. government customers.

If we fail to significantly increase our sales of ST-246 to customers other than the U.S. government, our business and opportunities for growth could be materially limited.

Because we must obtain regulatory clearance or otherwise operate under strict legal requirements in order to test and market our products in the U.S., we cannot predict whether or when we will be permitted to commercialize our products other than through the BARDA Contract.
 
     Except with respect to sales to BARDA under Project BioShield, pharmaceutical products cannot generally be marketed in the U.S. until they have has completed rigorous pre-clinical testing and clinical trials and an extensive regulatory clearance process implemented by FDA. Pharmaceutical products typically take many years to satisfy regulatory requirements and require the expenditure of substantial resources depending on the type, complexity and novelty of the product and its intended use.
 
Before commencing clinical trials in humans, we must submit and receive clearance from FDA by means of an IND application. Institutional review boards and FDA oversee clinical trials and such trials:


15

Table of Contents

must be conducted in conformance with FDA regulations;

must meet requirements for institutional review board oversight;

must meet requirements for informed consent;

must meet requirements for good clinical and manufacturing practices;

are subject to continuing FDA oversight;

may require large numbers of test subjects; and

may be suspended by us or FDA at any time if it is believed that the subjects participating in these trials are being exposed to unacceptable health risks or if FDA finds deficiencies in our IND application or the conduct of these trials.

Before receiving FDA clearance to market a product in the absence of a medical or public health emergency, we must demonstrate that the product is safe and effective on the patient population that will be treated. Data we obtain from pre-clinical and clinical activities and from animal models are susceptible to varying interpretations that could delay, limit or prevent regulatory clearances. Additionally, we have limited experience in conducting and managing the pre-clinical and clinical trials and animal efficacy studies and manufacturing processes necessary to obtain regulatory clearance.

If full regulatory clearance of a product is granted, this clearance will be limited only to those states and conditions for which the product is demonstrated through clinical trials to be safe and efficacious. We cannot ensure that any compound developed by us, alone or with others, will prove to be safe and efficacious in pre-clinical or clinical trials or animal efficacy studies and will meet all of the applicable regulatory requirements needed to receive full marketing clearance.
 
The biopharmaceutical market in which we compete and will compete is highly competitive.
 
The biopharmaceutical 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 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 we have no experience. Many of these companies also have manufacturing facilities and established marketing capabilities that would enable such companies to market competing products through existing channels of distribution.
 
Our potential products may not be acceptable in the market or eligible for third-party reimbursement resulting in a negative impact on our future financial results.
 
Any product we develop may not achieve market acceptance. The degree of market acceptance of any of our products will depend on a number of factors, including:

the establishment and demonstration in the medical community of the efficacy and safety of such products;

the potential advantage of such products over existing approaches to combating the problem intended to be addressed;

the cost of our products relative to their perceived benefits; and

payment or reimbursement policies of government and third-party payors.

Physicians, patients or the medical community in general may not accept or utilize any product we may develop. Our ability to generate revenues and income with respect to drugs, if any, developed through the use of our technology will depend, in part, upon the extent to which payment or reimbursement for the cost of such drugs will be available from third-party payors, such as governmental suppliers such as BARDA, CDC or DoD, governmental health administration authorities, private healthcare insurers, health maintenance organizations, pharmacy benefits management companies and other organizations. Third-party payors

16

Table of Contents

are increasingly disputing the prices charged for pharmaceutical products. If third-party payment or reimbursement was not available or sufficient to allow profitable price levels to be maintained for drugs we develop, it could adversely affect our business.
 
Product liability lawsuits could cause us to incur substantial liabilities and require us to limit commercialization of any products that we may develop.
 
We face an inherent business risk related to the sale of ST-246 and any other products that we successfully develop and the testing of our product candidates in clinical trials.

ST-246 is currently identified as a covered countermeasure under a PREP Act declaration issued in October 2008, which provides us with immunity with respect to the manufacture, administration or use of ST-246. Under our BARDA Contract, the U.S. government should indemnify us against claims by third parties for death, personal injury and other damages related to ST-246, 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 can be lengthy and complicated, and there is no guarantee that we will 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 substantial liabilities. Regardless of merit or eventual outcome, product liability claims may result in:

decreased demand for any product candidate or product that we may develop;

injury to our reputation;

withdrawal of a product from the market;

withdrawal of clinical trial participants;

costs to defend the related litigation;

substantial monetary awards to trial participants or patients;

loss of revenue; and

the inability to commercialize any products that we may develop.

We currently have product liability insurance with coverage up to a $10 million annual aggregate limit and up to $10 million per occurrence. The amount of insurance that we currently hold may not be adequate to cover all liabilities that may occur. Product liability insurance is difficult to obtain and increasingly expensive. 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.

Additionally, a successful product liability claim or series of claims brought against us could cause our stock price to fall and could decrease our financial resources and materially and adversely affect our business.

We may be required to perform additional clinical trials or change the labeling of our products if we or others identify side effects after our products are on the market, which could harm sales of the affected products.
 
If we or others identify side effects after any of our products are on the market, 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 our manufacturing facilities may be required;
 
sales of the affected products may drop significantly;

17

Table of Contents

 
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 sales of the affected products or could increase the costs and expenses of commercializing and marketing these products.
 
Healthcare reform and controls on healthcare spending may limit the price we charge for our products and the amounts that we can sell.
 
The U.S. government and private insurers have considered ways to change, and have changed, the manner in which healthcare services are provided in the U.S. Potential approaches and changes in recent years include controls on healthcare spending and the creation of large purchasing groups. In the future, the U.S. government may institute further controls and limits on healthcare spending, including through the Medicare and Medicaid programs. These controls and limits might affect the payments we could collect from sales of any products. Uncertainties regarding future healthcare reform and private market practices could adversely affect our ability to sell any of our products profitably in the U.S. Similar or other changes to payment systems abroad could adversely affect foreign sales.
 
Laws and regulations governing international operations may preclude us from developing, manufacturing and selling certain product candidates outside of the United States and require us to develop and implement costly compliance programs.
 
We have begun to expand our operations outside of the United States, and we must comply with numerous laws and regulations relating to our business operations in each jurisdiction in which we plan to operate. The creation and implementation of international business practices compliance programs is costly and such programs are difficult 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 of 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. The anti-bribery provisions of the FCPA are enforced primarily by the U.S. Department of Justice. The SEC is involved with enforcement of the books and records provisions of the FCPA.
 
Compliance with the FCPA is expensive and difficult, particularly in countries in which corruption is a recognized problem. In addition, the FCPA presents particular challenges in the pharmaceutical industry, because, in many countries, hospitals are operated by the government, and doctors and other hospital employees are considered foreign officials. 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. Our expanding presence outside of the United States will require us to dedicate additional resources to compliance with these laws, and these laws may preclude us from developing, manufacturing, or selling certain products and product candidates outside of the United States, which could limit our growth potential and increase our development costs.
 
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. 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 governmental contractor. The termination of a governmental contract or relationship as a result of our failure to satisfy any of our obligations under laws governing international business practices would have a negative impact on our operations and harm our reputation and ability to procure governmental contracts. The SEC also may suspend or bar issuers from trading securities on United States exchanges for violations of the FCPA’s accounting provisions.

If we are unable to expand our internal sales and marketing capabilities or enter into agreements with third parties, we may be unable to generate revenue from product sales to customers other than the U.S. government.

To achieve commercial success for any approved product, we may need to further develop our own sales and marketing capabilities, enter into collaborations with third parties able to perform these services or outsource these functions to third parties.

We currently market and sell ST-246 through a small, targeted sales and marketing group. We plan to continue to do so and expect that we will use a similar approach for sales to the U.S. government of any other biodefense product candidates that we successfully develop. If we are unable to do this, we may be unable to achieve our revenue goals in respect of ST-246, which could have an adverse effect on our growth.
 
Risks Related to Manufacturing and Manufacturing Facilities
 
Problems related to large-scale commercial manufacturing could cause us to delay product launches or experience shortages of products.
 
Manufacturing drug products, especially in large quantities, is complex. Our drug candidates require several manufacturing steps, 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 customer orders or contractual commitments, lead to delays in our clinical trials or result in litigation or regulatory action.
 
If third parties do not manufacture our drug candidates or products in sufficient quantities and at an acceptable cost or in compliance with regulatory requirements and specifications, the development and commercialization of our drug candidates could be delayed, prevented or impaired.
 
We currently rely on third parties to manufacture drug candidates that we require for pre-clinical and clinical development, including ST-246. Any significant delay in obtaining adequate supplies of our drug candidates could adversely affect our ability to develop or commercialize these drug candidates. We expect that we will rely on third parties for a portion of the manufacturing process for commercial supplies of drug candidates that we successfully develop. If our contract manufacturers are unable to scale-up production to generate enough materials for commercial launch, the success of those 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 commercialize any product that receives regulatory approval on a timely and competitive basis.
 
We currently rely on third parties to demonstrate regulatory compliance 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 FDA and corresponding state and foreign agencies or their designees to ensure strict compliance with applicable 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. While our Grants call for compliance with all applicable regulatory requirements, we do not control compliance by these manufacturers with these regulations and standards. If we or these third parties fail to comply with applicable regulations, sanctions could be imposed on us, which could significantly and adversely affect supplies of our drug candidates.

Our activities may involve hazardous materials, use of which may subject us to environmental regulatory liabilities.
 
Our biopharmaceutical research and development sometimes involves the controlled use of hazardous and radioactive materials and 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. Although we believe that our 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. Our research and development activities do not produce any unusual hazardous products. We

19

Table of Contents

do use 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.
 
We believe that we are in compliance in all material respects with applicable environmental laws and regulations and currently do not expect to make material additional capital expenditures for environmental control facilities in the near term. However, we may have to incur significant costs to comply with current or future environmental laws and regulations.
 
Risks Related to Sales of Biodefense Products to the U.S. Government
 
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 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, while 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 or prohibition from doing business with the U.S. government.

In June 2009, we became aware that we had not complied with certain HHS regulations requiring the submission of yearly audited statements to the Office of the Inspector General (“OIG”) Office of Audit Services. We submitted the required audits and related statements to the OIG Office of Audit Services. No enforcement action has been taken in this matter, but there can be no assurance that no enforcement action will be taken at some future time with respect to this matter or any similar matter if similar or related problems are uncovered at some future time.

Laws and regulations affecting government Grants might make it more costly and difficult for us to successfully conduct our business.
 
We must comply with numerous laws and regulations relating to the formation, administration and performance of government Grants, which can make it more difficult for us to retain our rights under these contracts. These laws and regulations affect how we do business with federal, state and local governmental agencies. 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;
 
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 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.

Risks Related to Regulatory Approvals
 
If we are not able to obtain required regulatory approvals, we will not be able to commercialize our drug candidates in the United States other than through sales to BARDA under Project BioShield , and our ability to generate revenue will be materially impaired.
 
Our drug candidates and the activities associated with their development and commercialization, including their testing, manufacture, safety, efficacy, recordkeeping, labeling, storage, approval, advertising, promotion, sale and distribution, are subject to comprehensive regulation by FDA and other regulatory agencies in the United States and by comparable authorities in other countries. Failure to obtain regulatory approval for a drug candidate will prevent us from commercializing the drug candidate in the United States other than through sales to BARDA under Project BioShield. We have limited experience in preparing, filing and prosecuting the applications necessary to gain regulatory approvals and expect to rely on third-party contract research organizations and consultants to assist us in this process. Securing FDA approval requires the submission to FDA of extensive pre-clinical and clinical data and, potentially, animal efficacy studies, information about product manufacturing processes and inspection of facilities and supporting information in order to establish the drug candidate’s safety and efficacy. Our future products may not be effective, may be only moderately effective, or may prove to have significant side effects, toxicities, or other characteristics that may preclude our obtaining regulatory approval or prevent or limit commercial use.
 
Failure to obtain regulatory approval in international jurisdictions could prevent us from marketing our products abroad.
 
We intend to have our products marketed outside the United States. To market our products in the European Union and many 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. The time required to obtain approval may differ from that required to obtain FDA approval.
 
The foreign regulatory approval process may include all of the risks associated with obtaining FDA approval. We may not obtain foreign regulatory approvals on a timely basis, if at all. Approval by FDA does not ensure approval by regulatory authorities in other countries or jurisdictions, and approval by one foreign regulatory authority does not ensure approval by regulatory authorities in other foreign countries or jurisdictions or by FDA. We and our potential future collaborators may not be able to file for regulatory approvals and may not receive necessary approvals to commercialize our products in any market.

The Fast Track designation for ST-246 may not actually lead to a faster development or regulatory review or approval process.
 
We have obtained a “Fast Track” designation from FDA for ST-246. However, we may not experience a faster development process, review or approval compared to conventional FDA procedures. FDA may withdraw our Fast Track designation if it believes that the designation is no longer supported by data from our clinical development program. Our Fast Track designation does not guarantee that we will qualify for or be able to take advantage of FDA’s expedited review procedures or that any application that we may submit to FDA for regulatory approval will be accepted for filing or ultimately approved.
 
Risks Related to Our Dependence on Third Parties
 
If third parties on whom we rely for clinical trials or certain animal trials do not perform as contractually required or as we expect, we may not be able to obtain regulatory approval for or commercialize our drug candidates and our business may suffer.
 
We do not have the ability to independently conduct the clinical trials, and certain animal trials, required to obtain regulatory approval for our products. We depend on independent investigators, contract research organizations and other third-party service providers to conduct trials of our drug candidates and expect to continue to do so. We rely heavily on these third parties for successful execution of our trials, but do not exercise day-to-day control over their activities. We are responsible for ensuring that each of our trials is conducted in accordance with the general investigational plan and protocols for the trial. Moreover, FDA requires us to comply with standards, commonly referred to as Good Clinical Practices, for conducting and recording and reporting the results of clinical trials to assure that data and reported results are credible and accurate and that the rights, integrity and confidentiality of trial participants are protected. Similarly, animal trials may have to comply with Good Laboratory Practices.

We also currently rely on third-party manufacturers and service providers to produce ST-246. Under the BARDA Contract, we are responsible for the performance of these third-party contracts, and our contracts with these third parties give us certain supervisory and quality control rights, but we do not exercise complete day-to-day control over their activities.
 
     Our reliance on third parties that we do not control does not relieve us of the responsibilities and requirements imposed by the BARDA Contract. Third parties may not complete activities on schedule, or may not conduct our trials in accordance with

21

Table of Contents

regulatory requirements or our stated protocols. The failure of these third parties to carry out their obligations could delay or prevent the development, approval and commercialization of our drug candidates.
 
Risks Related to Our Intellectual Property
 
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 patent protection for our proprietary technologies, drug targets and potential products and to effectively 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 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 has emerged to date. Accordingly, we cannot predict the type and breadth of claims allowed in these patents.
 
As of December 31, 2011, we exclusively own 8 U.S. patents, 1 U.S. provisional patent applications, 18 U.S. utility patent applications, 4 international PCT patent applications and 127 foreign patent applications. We included a summary of our patent position as of December 31, 2011 in Part I, Item 1 of this Annual Report on Form 10-K.
 
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 to or from others on unfavorable terms. 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.
 
The costs to establish or defend against claims of infringement or interference with patents or other proprietary rights can be expensive 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 have a material adverse effect on us. We could incur substantial costs if we are required to defend ourselves in suits brought by third parties or if we initiate such suits. We may not have sufficient funds or resources in the event of litigation. Additionally, we may not prevail in any such action.
 
Any dispute resulting from claims based on patents and proprietary rights could result in a significant reduction in the coverage of the patents or proprietary rights owned, optioned by or licensed to us and limit our ability to obtain meaningful protection for our rights. If patents are issued to third parties that contain competitive or conflicting claims, we may be legally prohibited from researching, developing or commercializing potential products or be required to obtain licenses to these patents or to develop or obtain alternative technology. We may be legally prohibited from using technology owned by others, may not be able to obtain any license to the patents or technologies of third parties on acceptable terms, if at all, or may not be able to obtain or develop alternative technologies.
 
In December 2006, PharmAthene, Inc. (“PharmAthene”) filed an action against us in the Delaware Court of Chancery captioned PharmAthene, Inc. v. SIGA Technologies, Inc., C.A. No. 2627-N. In its amended complaint, PharmAthene asks the Court to order us to enter into a license agreement with PharmAthene with respect to ST-246, as well as issue a declaration that we are obliged to execute such a license agreement, and award damages resulting from our supposed breach of that obligation. PharmAthene also alleges that we breached an obligation to negotiate such a license agreement in good faith, as well as seeks damages for promissory estoppel and unjust enrichment based on supposed information, capital and assistance that PharmAthene allegedly provided to us during the negotiation process. A trial was held on PharmAthene’s claims in January 2011.
In September 2011, the Court of Chancery issued its post-trial opinion. The Court denied PharmAthene’s requests for

22

Table of Contents

specific performance and expectation damages measured by the present value of estimated future profits. However, the Court held that we breached our duty to negotiate in good faith and were liable under the doctrine of promissory estoppel. The Court consequently awarded to PharmAthene what the court described as an equitable payment stream or equitable lien consisting of fifty percent of the net profits that we achieve from sales of ST-246 after we secure the first $40 million in net profits, for ten years following the first commercial sale. In addition, PharmAthene was awarded one-third of its reasonable attorney fees and expert witness expenses. Based on certain documents provided to the Court by PharmAthene in January 2012, we recorded a loss contingency of approximately $2.0 million as of December 31, 2011 for such attorney fees and expert witness expenses. The difference between the amount accrued and PharmAthene’s request for $2.7 million relates to amounts currently in dispute.
We filed a motion for reargument in October 2011, requesting that the Court vacate its award of an equitable payment stream or equitable lien. In December 2011, the Court denied our motion.
The timing and amount of payments to be made pursuant to the Court’s September 2011 ruling remain uncertain. Determination of these matters requires both clarification as to the application of the Court’s post-trial ruling and the timing and amount of payments to us for sales of ST-246. Thus, we are unable to estimate a range of loss that may result from implementation of the Court’s post-trial ruling with respect to ST-246 sales, although this ruling is likely to have a materially adverse impact unless we are successful in any subsequent appeal of the Court’s final judgment. We cannot assure the success of any such appeal.
In addition, 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 Financial Position and Need for Additional Financing
 
We have incurred operating losses since our inception and expect to incur net losses and negative cash flow for the foreseeable future.

We incurred net operating losses of approximately $31.4 million and $12.7 million for the years ended December 31, 2011 and 2010, respectively. As of December 31, 2011, 2010, and 2009, our accumulated deficit was approximately $108.9 million, $122.5 million, and $94.3 million, respectively. We expect to continue to have significant operating expenses and will need to generate significant revenues to achieve and maintain profitability.
 
Our profitability is substantially dependent on revenues from ST-246 product sales. If we do not achieve profitability, we cannot guarantee that we can sustain or increase profitability on a quarterly or annual basis in the future and we expect that revenues will fluctuate significantly from quarter to quarter based on several factors, including the timing of fulfilling orders for the U.S. government. If revenues grow slower than we anticipate, or if operating expenses or expenses resulting from the post-trial ruling in the litigation commenced by PharmAthene exceed our expectations or cannot be adjusted accordingly, then our business, results of operations, financial condition and cash flows will be materially and adversely affected. Because our strategy may include the acquisition of other businesses, acquisition and integration expenses and any cash required to fund these acquisitions will reduce our available cash.
 
Our business may suffer if we are unable to raise additional equity funding.
 
Until we begin to receive payments related to our performance under the BARDA Contract, our operations may be constrained by our ability to raise money through the exercise of existing options or warrants or through the issuance of new equity. While we have raised substantial funds through 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. If we are unable to raise additional equity funds, we may be forced to discontinue, cease or limit certain operations. We currently have sufficient operating capital to finance our operations for at least the next twelve months. Our annual operating needs vary from year to year depending upon the amount of cash generated through the BARDA Contract, Grants and licenses, the amount of projects we undertake, and the amount of resources we expend in connection with acquisitions, all of which may materially differ from year to year and may adversely affect our business.
 
Any additional equity that we raise 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.

Risks Related to Our Common Stock
 
Our stock price is, and we expect it to remain, volatile, which could limit investors’ ability to sell stock at a profit.
 
The volatile price of our stock makes it difficult for investors to predict the value of their investments, to sell shares at a profit at any given time, or to plan purchases and sales in advance. A variety of factors may affect the market price of our common stock. These include, but are not limited to:

publicity regarding actual or potential clinical or animal test results relating to products under development by our competitors or us;

initiating, completing or analyzing, or a delay or failure in initiating, completing or analyzing, pre-clinical or clinical trials or animal trials or the design or results of these trials;

achievement or rejection of regulatory approvals by our competitors or us;

announcements of technological innovations or new commercial products by our competitors or us;

developments concerning proprietary rights, including patents and rights to ST-246 or a portion of the net profits associated therewith as asserted by PharmAthene;

developments concerning our collaborations;

regulatory developments in the United States and foreign countries;

 economic or other crises and other external factors;
 
period-to-period fluctuations in our revenues and other results of operations; and

changes in financial estimates by securities analysts.

Additionally, because the volume of trading in our stock fluctuates significantly at times, any information about us in the media may result in significant volatility in our stock price.
 
We will not be able to control many of these factors, and we believe that period-to-period comparisons of our financial results will not necessarily be indicative of our future performance.
 
In addition, the stock market in general, and the market for biotechnology companies in particular, has experienced extreme price and volume fluctuations that may have been unrelated or disproportionate to the operating performance of individual companies. These broad market and industry factors may seriously harm the market price of our common stock, regardless of our operating performance.
 
We identified a material weakness, which we subsequently remediated, in our internal control over financial reporting that resulted in the restatement of our consolidated financial statements included in our 2009 Annual Report on Form 10-K/A.
 
Our management is responsible for maintaining internal control over financial reporting designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of consolidated financial statements for external purposes in accordance with generally accepted accounting principles. Our management assessed the effectiveness of our internal control over financial reporting as of December 31, 2009, and identified a material weakness related to the failure to ensure timely application of certain anti-dilution provisions contained in certain outstanding warrant arrangements. As a result of this material weakness, our management concluded that our internal control over financial reporting and our disclosure controls and procedures were not effective as of December 31, 2009.  We subsequently remediated this control.

A material weakness is a deficiency, or combination of deficiencies, in internal control over financial reporting such that there is a reasonable possibility that a material misstatement of our annual or interim consolidated financial statements will not be prevented or detected on a timely basis. The effectiveness of any controls or procedures is subject to certain limitations, and as a result, there can be no assurance that our controls and procedures will detect all errors or fraud. A control can provide only reasonable, not absolute, assurance that the objectives of the control system will be attained. We also cannot assure you that other material weaknesses will not arise as a result of failures to maintain adequate internal controls and procedures or that circumvention of

24

Table of Contents

those controls and procedures will not occur. Additionally, even our improved controls and procedures may not be adequate to prevent or identify errors or irregularities or ensure that our financial statements are prepared in accordance with generally accepted accounting principles. If we cannot maintain and execute adequate internal control over financial reporting or implement required new or improved controls that provide reasonable assurance of the reliability of the financial reporting and preparation of our financial statements for external use, we could suffer harm to our reputation, fail to meet our public reporting requirements on a timely basis, or be unable to properly report on our business and the results of our operations, and the market price of our securities could be materially adversely affected.
 
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 10,000,000 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, while providing desirable flexibility in connection with our future activities, could also 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 in control.

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. They also have, through the exercise or conversion of certain securities, the right to acquire additional common stock. As a result, these stockholders, if acting together, have the ability to significantly influence the outcome of corporate actions requiring shareholder approval. Additionally, this concentration of ownership may have the effect of delaying or preventing a change in control of SIGA. As of the most recent available information, directors, officers and principal stockholders beneficially owned approximately 33% of our outstanding stock.     

Risks Related to Our Business
 
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. Our success is dependent upon our personnel and our ability to recruit 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 of our key management could have a material adverse effect on our business.

Our future success depends on our ability to retain our chief executive officer and other key executives and to attract, retain and motivate qualified personnel. The loss of the services of any key executive might impede the achievement of our research, development and commercialization objectives. Replacing key employees may be difficult and time-consuming because of the limited number of individuals in our industry with the skills and experiences required to develop, gain regulatory approval of and commercialize our product candidates successfully. We generally do not maintain key person life insurance to cover the loss of any of our employees. Recruiting and retaining qualified scientific personnel, clinical personnel and sales and marketing personnel will also be critical to our success. We may not be able to attract and retain these personnel on acceptable terms, if at all, given the competition among numerous pharmaceutical and biotechnology companies for similar personnel. We also experience competition for the hiring of scientific and clinical personnel from other companies, universities and research institutions. In addition, we rely on consultants and advisors, including scientific and clinical advisors, to assist us in formulating our research and development, regulatory and commercialization strategy. Our consultants and advisors may be employed by employers other than us and may have commitments under consulting or advisory contracts with other entities that may limit their availability to us.

We may have difficulty managing our growth.
 
During 2011, we have experienced, in part due to our need to perform under the BARDA Contract, and may in the future experience growth in the number of our employees and the scope of our operations. This potential future growth could place a significant strain on our management and operations. Our ability to manage growth will depend upon our ability to broaden our management team and our ability to attract, hire and retain skilled employees. Our success will also depend on the ability of our officers and key employees to continue to implement and improve our operational and other systems and to hire, train and manage our employees.

Our ability to use our net operating loss carryforwards may be limited.
 
As of December 31, 2011, we had federal net operating loss carryforwards, or NOLs, of $90.6 million to offset future taxable income. In 2011, approximately $0.9 million of previously available NOLs expired and approximately $1.2 million expires in 2012 if not utilized, with the remainder expiring in various years between 2018 and 2031. Under the provisions of the Internal Revenue Code, substantial changes in our ownership, in certain circumstances, will limit the amount of NOLs that can be utilized annually in the future to offset taxable income. In particular, section 382 of the Internal Revenue Code imposes limitations on a company’s ability to use NOLs if a company experiences a more-than-50% ownership change over a three-year period. If we are limited in our ability to use our NOLs in future years in which we have taxable income, we will pay more taxes than if we were able to utilize our NOLs fully. For example, as a result of a previous change in stock ownership, the annual utilization of the net operating carryforwards generated in tax years prior to 2004 may be subject to limitation.
    
In addition, existing rulings in the litigation with PharmAthene, if not overturned in subsequent proceedings, may limit our future profitability and therefore our ability to generate future taxable income that we can use our carryforwards to offset.


Item 1B. Unresolved Staff Comments
 
None.

Item 2. Properties
 
Our headquarters are located in New York City, and our research and development facilities are located in Corvallis, Oregon. In New York, we occupy approximately 2,450 square feet under an Office Service Agreement with an affiliate of a shareholder that, as currently amended, is cancelable upon 60 days notice. In Corvallis, we lease approximately 32,700 square feet under an amended lease agreement signed in January 2007, which was amended and extended on June 1, 2011. The Company formerly occupied 5,700 square feet under a sublease agreement signed in January 2010 which expired in September 2011. Our facility in Oregon has been improved to meet the special requirements necessary for the operation of our research and development activities. The facilities leased in Corvallis includes space existing under the prior lease terms and newly constructed space in the same building under the most recent lease amendment. We believe that our current facilities are adequate to our needs.

Item 3. Legal Proceedings
 
In December 2006, PharmAthene, Inc. (“PharmAthene”) filed an action against us in the Delaware Court of Chancery captioned PharmAthene, Inc. v. SIGA Technologies, Inc., C.A. No. 2627-N. In its amended complaint, PharmAthene asks the Court to order us to enter into a license agreement with PharmAthene with respect to ST-246, as well as issue a declaration that we are obliged to execute such a license agreement, and award damages resulting from our supposed breach of that obligation. PharmAthene also alleges that we breached an obligation to negotiate such a license agreement in good faith, as well as seeks damages for promissory estoppel and unjust enrichment based on supposed information, capital and assistance that PharmAthene allegedly provided to us during the negotiation process. A trial was held on PharmAthene’s claims in January 2011.

In September 2011, the Court of Chancery issued its post-trial opinion. The Court denied PharmAthene’s requests for specific performance and expectation damages measured by present value of estimated future profits. However, the Court held that we breached our duty to negotiate in good faith and were liable under the doctrine of promissory estoppel. The Court consequently awarded to PharmAthene what the Court described as an equitable payment stream or equitable lien consisting of fifty percent of the net profits that we achieve from sales of ST-246 after we secure the first $40 million in net profits, for ten years following the first commercial sale. In addition, PharmAthene was awarded one-third of its reasonable attorney fees and expert witness expenses. Based on certain documents provided to the Court by PharmAthene in January 2012, we recorded a loss contingency of approximately $2.0 million as of December 31, 2011 for such attorney fees and expert witness expenses. The difference between the amount accrued and PharmAthene’s request for $2.7 million relates to amounts currently in dispute.

We filed a motion for reargument in October 2011, requesting that the Court vacate its award of an equitable payment stream or equitable lien. In December 2011, the Court denied our motion.

The timing and amount of payments to be made pursuant to the Court’s September 2011 ruling remain uncertain. Determination of these matters requires both clarification as to the application of the Court’s post-trial ruling and the timing and amount of payments to us for sales of ST-246. Thus, we are unable to estimate a range of loss that may result from implementation of the Court’s post-trial ruling with respect to ST-246 sales, although such resolution is likely to have a materially adverse impact unless we are successful in any subsequent appeal of the Court’s final judgment. We cannot assure the success of any such appeal.

Price Range of Common Stock

Our common stock trades under the symbol “SIGA”. Our common stock has been traded on the Nasdaq Global Market since September 3, 2009 and, prior to such date, had been traded on the Nasdaq Capital Market since September 9, 1997. Prior to that time there was no public market for our common stock. The following table sets forth, for the periods indicated, the high and low sales prices for the common stock, as reported on the Nasdaq Global Market:

As of February 15, 2012, the closing sale price of our common stock was $3.11 per share. There were 44 holders of record as of February 15, 2012. We believe that the number of beneficial owners of our common stock is substantially greater than the number of record holders, because a large portion of common stock is held in broker “street names”.
 
We have paid no dividends on our common stock and do not expect to pay cash dividends in the foreseeable future. We are not under any restriction as to our present or future ability to pay dividends. We currently intend to retain any future earnings to finance the growth and development of our business.

Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations
 
The following discussion should be read in conjunction with our consolidated financial statements and notes to those statements and other financial information appearing elsewhere in this Annual Report on Form 10-K. In addition to historical information, the following discussion and other parts of this Annual Report contain forward-looking information that involves risks and uncertainties.
 
Overview
 
We are a pharmaceutical company specializing in the development and commercialization of pharmaceutical solutions for some of the most lethal disease-causing pathogens in the world - smallpox, Ebola, dengue, Lassa fever and other dangerous viruses. Our business is to discover, develop, manufacture and successfully commercialize drugs to prevent and treat these high-priority threats. Our mission is to disarm dreaded viral diseases and create robust, modern biodefense countermeasures.    

Commercial Product - ST-246®

The Company’s lead product, ST-246, is an orally administered antiviral drug that targets orthopoxviruses. On May 13, 2011, SIGA signed the BARDA Contract pursuant to which we agreed to deliver two million courses of ST-246 to the Strategic Stockpile. The five-year base contract award is worth approximately $435 million, and the BARDA Contract also includes various options to be exercised at BARDA’s discretion. As originally issued, the BARDA Contract included an option for the purchase of up to 12 million additional courses of ST-246; however, following a protest by a competitor of the Company, BARDA issued a contract modification on June 24, 2011 pursuant to which it deleted the option to purchase the additional courses. Under the BARDA Contract as modified, BARDA has agreed to buy from SIGA 1.7 million courses of ST-246. Additionally, SIGA will contribute to BARDA 300,000 courses manufactured using federal funds provided by HHS under prior development contracts. The BARDA Contract as modified also contains options that will permit SIGA to continue its work on pediatric and geriatric versions of the drug as well as use ST-246 for smallpox prophylaxis. As discussed in Item 3, “Legal Proceedings”, the amount of profits we are likely to retain pursuant to the BARDA Contract is dependent upon resolution of the pending dispute described in such section.

We believe ST-246 will be the first entirely new small-molecule drug delivered to the Strategic Stockpile under Project BioShield. FDA has designated ST-246 for “fast-track” status, creating a path for expedited FDA review and eventual regulatory approval.
    
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. 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 the valuation of stock options and warrants, revenue recognition, impairment of assets and income taxes. Below, we discuss these policies further, as well as the estimates and judgments involved.

Critical Accounting Policies
 
The following is a brief discussion of the significant accounting policies and methods used by us in the preparation of our consolidated financial statements. Note 2 of the Notes to the Consolidated Financial Statements includes a summary of all of the significant accounting policies.
 
Share-based Compensation
     We account for our stock-based compensation using the fair value recognition provisions prescribed by the authoritative guidance, which requires the measurement and recognition of compensation expense for all share-based payment awards made to employees and directors including employee stock options based on estimated fair values.
 
Stock-based compensation expense for 2011, 2010 and 2009 was $12.5 million, $1.5 million and $2.1 million, respectively. The fair value of share-based awards is determined on the grant date; for options awards, fair value is estimated using the Black-Scholes model. The value of the portion of the award that is ultimately expected to vest is recorded as expense over the requisite

30

Table of Contents

periods in our consolidated statement of operations. Determining the fair value of stock-based awards at the grant date requires judgment, including estimating the expected term over which stock awards will be outstanding before they are exercised, the expected volatility of our stock, and the number of stock-based awards that are expected to be forfeited. It is reasonably likely that future assumptions may change, in which case the fair value of future option awards may exceed or fall short of historical calculated fair values. In addition, for stock options with performance conditions, on a quarterly basis we estimate the most probable outcome of the performance conditions in order to determine the amount of compensation costs to be recorded over the remaining vesting period.

Fair Value of Financial Instruments
The carrying value of cash and cash equivalents, accounts receivables, short-term investments, accounts payable and accrued expenses 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.
 
We use model-derived valuations where inputs are observable in active markets to determine the fair value of certain common stock warrants on a recurring basis and classify such warrants in Level 2. The Black-Scholes model utilizes inputs consisting of: (i) the closing price of our common stock; (ii) the expected remaining life of the warrants; (iii) the expected volatility using a weighted-average of historical volatilities of SIGA and a group of comparable companies; and (iv) the risk-free market rate. At December 31, 2011 and 2010, the fair value of such warrants was $622,938 and $10,524,660, respectively, classified as non-current common stock warrants on the balance sheet.

As of December 31, 2010, we held approximately $15.0 million in United States Treasury Bills, classified as a Level 1 security. For the years ended December 31, 2011 and 2010, we did not hold any Level 3 securities.
 
Revenue Recognition
Revenue is recognized when persuasive evidence of an arrangement exists, delivery has occurred, the fee is fixed and determinable, collectability is reasonably assured, contractual obligations have been satisfied and title and risk of loss have been transferred to the customer. We recognize revenue from non-refundable up-front payments, not tied to achieving a specific performance milestone, over the period which we are obligated to perform services or based on the percentage of costs incurred to date, estimated costs to complete and total expected contract revenue. Payments for development activities are recognized as revenue is earned, over the period of effort. Funding for the acquisition of capital assets under cost-plus-fee Grants is evaluated for appropriate recognition as a reduction to the cost of the acquired asset, a financing arrangement, or revenue, based on the specific terms of the related grant or contract. Substantive at-risk milestone payments, which are based on achieving a specific performance milestone, are recognized as revenue when the milestone is achieved and the related payment is due, providing there is no future service obligation associated with that milestone. In situations where we receive payment in advance of the performance of services, such amounts are deferred and recognized as revenue as the related services are performed.
 
Goodwill
The purchase price of an acquired company is allocated between intangible assets and the net tangible assets of the acquired business with the residual of the purchase price recorded as goodwill. The determination of the fair value of the intangible assets acquired and liabilities assumed involves certain judgments and estimates.

At December 31, 2011, our goodwill totaled $898,000. We evaluate goodwill for impairment at least annually or as circumstances warrant. Goodwill is tested for recoverability between annual evaluations whenever events or changes in circumstances indicate that the carrying amounts may not be recoverable. The impairment review process compares the fair value of the reporting unit in which goodwill resides to its carrying value. In 2011, we operated as one business and one reporting unit. Therefore, the goodwill impairment analysis was performed on the basis of the Company as a whole using our market capitalization as an estimate of our fair value. In the past, our market capitalization has been significantly in excess of our carrying value. It is

31

Table of Contents

possible that our future market capitalization may fall short of our current market capitalization, in which case a potential impairment could result. Also, the use of an alternative method, such as the discounted expected future cash flows or market comparables to evaluate the fair value of the Company as a whole will possibly produce different results than our market capitalization.
 
Income Taxes
Determining the consolidated provision for income tax expense, deferred tax assets and liabilities and related valuation allowance, if any, involves judgment. The recognition of a valuation allowance for deferred taxes requires management to make estimates and judgments about our future profitability which are inherently uncertain. On an on-going basis, we evaluate whether a valuation allowance is needed to reduce our deferred income tax assets to an amount that is more likely than not to be realized. The evaluation process includes assessing historical and current results in addition to future expected results. Upon determining that we would be able to realize our deferred tax assets, an adjustment to the deferred tax valuation allowance would increase income in the period we make such determination.

Our assessment that our deferred tax assets will be realized is based on estimates of future taxable income arising from the BARDA Contract. If the current estimates of future taxable income are reduced or not realized, including any impact of the pending dispute as described in Item 3 “Legal Proceedings”, our assessment regarding the realization of deferred tax assets could change. 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. Changes in estimates may occur often and can have a significant favorable or unfavorable impact on our operating results from period to period.
 
Recent Accounting Pronouncements
In September 2011, the Financial Accounting Standards Board (the “FASB”) issued updated accounting guidance which amended guidance on how to test goodwill for impairment. This update permits an entity to first assess qualitative factors to determine whether it is more likely than not that the fair value of a reporting unit is less than its carrying amount as a basis for determining whether it is necessary to perform a two-step goodwill impairment test. The updated guidance is effective for annual impairment tests performed in fiscal years beginning after December 15, 2011 with early adoption permitted. We expect that the adoption of this guidance will not have a material impact on our consolidated financial statements.

In May 2011, the FASB issued additional guidance on fair value measurements that clarifies the application of existing guidance and disclosure requirements, changes certain fair value measurement principles and requires additional disclosures about fair value measurements. The updated guidance is effective during interim and annual period beginning after December 15, 2011. We expect that the adoption of this guidance will not have a material impact on our consolidated financial statements.
    
In January 2010, the FASB issued updated accounting guidance for fair value measurements. This update provides amendments that require new disclosure as follows: (1) A reporting entity should disclose separately the amounts of significant transfers in and out of Level 1 and Level 2 fair-value measurements and describe the reasons for the transfers. (2) In the reconciliation for fair value measurements using significant unobservable inputs (Level 3), a reporting entity should present separately information about purchases, sales, issuances, and settlements (that is, on a gross basis rather than as one net number). This update provides amendments that clarify existing disclosures as follows: (1) A reporting entity should provide fair-value measurement disclosures for each class of assets and liabilities. A class is often a subset of assets or liabilities within a line item in the statement of financial position. A reporting entity needs to use judgment in determining the appropriate classes of assets and liabilities. (2) A reporting entity should provide disclosures about the valuation techniques and inputs used to measure fair value for both recurring and nonrecurring fair value measurements. Those disclosures are required for fair value measurements that fall in either Level 2 or Level 3. The new disclosures and clarifications of existing disclosures are effective for interim and annual reporting periods beginning after December 15, 2009, except for the disclosures about purchases, sales, issuances, and settlements in the roll-forward of activity in Level 3 fair-value measurements. Those disclosures are effective for fiscal years beginning after December 15, 2010, and for interim periods within those fiscal years. We adopted the amendments, and such adoption has not had a material impact on our consolidated financial statements.

Years ended December 31, 2011, 2010, and 2009.
 
Revenues from research and development contracts and grants for the years ended December 31, 2011 and 2010, were $12.7 million and $19.2 million, respectively. The decrease of $6.5 million, or 34%, relates to a $3.1 million decrease in revenue mainly due to the conclusion of a federal ST-246 contract in the third quarter of 2011, and to a $3.7 million revenue decrease attributable to the conclusion in 2010 of a federal grant mainly supporting development of a Lassa fever antiviral.
 
Revenues from research and development contracts and grants for the years ended December 31, 2010 and 2009, were $19.2 million and $13.8 million, respectively. The increase of $5.4 million or 39% mainly relates to a $2.2 million increase in revenue generated from federal Grants supporting our broad spectrum antiviral development program and a $2.4 million increase generated from federal Grants supporting our arenavirus antiviral program. Revenue generated from federal Grants supporting the development of ST-246 increased $904,000 during the year.
 
Selling, general and administrative expenses (“SG&A”) for the years ended December 31, 2011 and 2010 were $23.9 million and $8.1 million, respectively, reflecting an increase of approximately $15.8 million or 195%. The increase in SG&A expenses mainly relates to a $13.0 million increase in compensation expense, which includes an increase in non-cash stock-based compensation of approximately $11.1 million, and an increase of $2.0 million for an estimated loss contingency in connection with an ongoing legal dispute.

SG&A for the years ended December 31, 2010 and 2009 were $8.1 million and $7.5 million, respectively, reflecting an increase of approximately $598,000 or 8%. The increase in SG&A expenses were mainly due to an increase of $559,000 in legal fees, an increase of $260,000 in expenses supporting business development activities and an increase of $181,000 in insurance premiums. The increase was offset by a decline of $615,000 in compensation related expenditures, including stock-based compensation.
     
     Research and development (“R&D”) expenses were $18.4 million for the year ended December 31, 2011, a decrease of $4.3 million or 19% from the $22.7 million incurred during the year ended December 31, 2010. The decrease was primarily due to direct expenses supporting the development of ST-246 decreasing $4.8 million from the prior year, offset by an increase to employee compensation expenses as a result of hiring additional R&D personnel. As of December 31, 2011 and 2010, we had 61 and 57 full-time R&D personnel, respectively.

R&D expenses were $22.7 million for the year ended December 31, 2010, an increase of $5.2 million or 30% from the $17.4 million incurred during the year ended December 31, 2009. Expenditures related to programs for the development of a broad spectrum antiviral drug and an arenavirus antiviral drug increased $860,000 and $1.8 million, respectively. Expenses supporting the development of ST-246 increased $1.0 million from the prior year. In addition to the programs’ direct expenses, our employee compensation expenses increased $925,000 as a result of hiring additional R&D personnel. As of December 31, 2010 and 2009, we had 57 and 49 full-time R&D personnel, respectively. 

During the years ended December 31, 2011, 2010, and 2009, we incurred direct costs of $7.2 million, $12.2 million and $10.9 million, respectively, on the development of ST-246. During the year ended December 31, 2011, we spent $1.4 million on internal human resources dedicated to the drug’s development and $5.8 million mainly on manufacturing and clinical testing. During the year ended December 31, 2010, we spent $1.7 million on internal human resources dedicated to the drug’s development and $10.5 million mainly on packaging and manufacturing. For the year ended December 31, 2009, we spent $1.5 million on internal human resources dedicated to the drug’s development and $9.3 million mainly on clinical trials and manufacturing. From inception of the ST-246 development program to-date, we invested a total of $45.3 million in the program, of which $8.3 million supported internal human resources, and $37.0 million were used mainly for manufacturing, clinical and pre-clinical work. These

resources reflect research and development expenses directly related to the program. They exclude additional expenditures such as patent costs, allocation of indirect expenses, and other services provided by NIH and DoD.
 
During the years ended December 31, 2011, 2010, and 2009, we incurred direct costs of $1.7 million, $2.5 million and $384,000, respectively, to support the development of drug candidates for dengue fever, Lassa fever virus and other drug candidates for certain arenavirus pathogens and hemorrhagic fevers. During the year ended December 31, 2011, $799,000 was spent on internal human resources and $895,000 was spent mainly on the optimization and chemistry of lead antiviral compounds. During the year ended December 31, 2010, we spent $2.5 million for dengue fever, Lassa virus and other drug candidates for certain arenavirus pathogens and hemorrhagic fevers, of which $305,000 was mainly for internal human resources and $2.2 million for medicinal chemistry and pre-clinical testing of our drug candidates. For the year ended December 31, 2009, we spent $155,000 on internal human resources dedicated to the development of these drugs and $228,000 mainly to for testing of chemical compounds. From inception of these programs to date, we spent a total of $10.0 million related to the programs, of which $3.3 million and $6.7 million were expended on internal human resources and pre-clinical work, respectively. These resources reflect research and development expenses directly related to the programs. They exclude additional expenditures such as patent costs, allocation of indirect expenses, and other services provided by NIH and DoD.

     During the years ended December 31, 2011, 2010, and 2009, we spent $981,000, $1.5 million and $66,000, respectively, to support the development of a broad-spectrum antiviral drug candidate. During the year ended December 31, 2011, we incurred $329,000 mainly on internal human resources and $653,000 was incurred to support medicinal chemistry. During the year ended December 31, 2010, we spent $645,000 on internal human resources and $849,000 mainly on the optimization of lead antiviral compounds. During the year ended December 31, 2009, we spent $42,000 on internal human resources and $24,000 mainly on compound modeling software licenses. From the inception of our program to develop a broad-spectrum antiviral drug to-date, we have spent a total of $2.5 million related to the program, of which $1.0 million and $1.5 million were mainly expended on internal human resources and supporting medicinal chemistry and the optimization of lead antiviral compounds, respectively. These resources reflect expenses directly related to the program. They exclude additional expenditures such as patent costs, allocation of indirect expenses, and other services provided by NIH and DoD.
 
The majority of our product programs are in the early stage of development. As a result, we cannot make reasonable estimates of the potential cost for most of our programs to be completed or the time it will take to complete the programs. There is a high risk of non-completion of any program because of the lead time to program completion, scientific issues that may arise and uncertainty of the costs. However, we could receive additional grants, contracts or technology licenses in the short-term. The potential cash and timing is not known and we cannot be certain if they will ever occur. If we are unable to obtain additional federal funding in the required amounts, the development timeline for these products would slow or possibly be suspended.

Patent preparation expenses for the years ended December 31, 2011 and 2010 were $1.8 million and $1.1 million, respectively. The increase of $660,000 or 57% is mainly as a result of our continuing efforts to protect our lead drug candidates in expanded geographic territories.
 
Patent preparation expenses for the years ended December 31, 2010 and 2009 were $1.1 million and $734,000, respectively. The increase of $414,000 or 56% is mainly related to our efforts to protect our lead drug candidates in geographic territories including South Africa, Japan, China and Europe.
 
Changes in the fair value of certain warrants to acquire common stock are recorded as gains or losses. For the years ended December 31, 2011, 2010, and 2009, we recorded a gain of $8.9 million, a loss of $16.0 million and a loss of $7.5 million, respectively, reflecting changes in the fair market value of warrants and rights to purchase common stock during the respective years. The warrants and rights to purchase our common stock were recorded at fair market value and classified as liabilities. 

Other income for the years ended December 31, 2011, 2010, and 2009, was $13,000, $659,000 and $1,000, respectively. Other income normalized in 2011, after we received $648,000 from the U.S. government in 2010 for qualified therapeutic drug discovery tax grant. Other income in 2011, 2010 and 2009 consists of interest income on our cash and cash equivalents.

For the year ended December 31, 2011, the benefit from income taxes of $36.0 million mainly reflects the partial release of valuation allowance from deferred tax assets. Prior to June 30, 2011, we provided a tax valuation allowance in our United States federal and state deferred tax assets based on our evaluation that such assets were not “more likely than not” to be realized. We continuously evaluated additional facts representing positive and negative evidence in the determination of the realizability of deferred tax assets. Such deferred tax assets consist primarily of net operating loss carryforwards and temporary differences on intangible assets, depreciation and deferred research and development costs. In the second quarter of 2011, we determined that it was more likely than not that certain deferred tax assets would be realized, mainly due to the execution of the BARDA Contract, the scheduling of deferred tax assets and liabilities and future taxable income from operating activities. Accordingly, we

34

Table of Contents

released a portion of the related valuation allowance from deferred tax assets. If the current estimates of future taxable income are reduced or not realized, for example, based on the ultimate outcome of the pending dispute described in Item 3, "Legal Proceedings" the Company’s assessment regarding the realization of deferred tax assets could change. Future changes in the estimated amount of deferred taxes expected to be realized will be reflected in the Company’s financial statements in the period the estimate is changed with a corresponding adjustment to operating results. Changes in estimates may occur often and can have a significant favorable or unfavorable impact on the Company’s operating results from period to period. In 2011, approximately $0.9 million of previously available NOLs expired and approximately $1.2 million expires in 2012 if not utilized, with the remainder expiring in various years between 2018 and 2031.

Liquidity and Capital Resources
 
On December 31, 2011, we had $49.3 million in cash and cash equivalents. During the year ended December 31, 2011, we received $41.0 million in advance payments under the BARDA Contract and proceeds of $3.9 million from exercises of warrants and options to purchase shares of our common stock.
 
Operating activities
Net cash provided by operations for the year ended December 31, 2011 was $25.6 million and net cash used in operations during the years ended December 31, 2010, and 2009 was $10.8 million and $8.5 million, respectively. Operations generated net cash in 2011 primarily due to the receipt of $41 million in advance payments under the BARDA Contract. Cash flow from the advance payments was partially offset by several factors, including: (i) the increase in patent expense in our effort to protect our lead drug candidates; (ii) an increase in regulatory legal and advisory expenses; and (iii) an increase in compensation.

On December 31, 2011 and 2010, our accounts receivable balance was $2.6 million and $3.0 million, respectively. Our account receivable balances reflects the work performed during November and December 2011 under two ST-246 development contracts, one of which concluded in September 2011, as well as work performed in December under our dengue fever and Lassa fever antiviral development contracts. Funds outstanding under these contracts were collected during January and February 2012. Our accounts payable, accrued expenses and other current liabilities balance were $6.9 million and $4.3 million on December 31, 2011 and 2010, respectively. The increase is mainly due to an estimated loss contingency of $2.0 million related to a pending dispute (as described in Item 3, “Legal Proceedings”).
 
Investing activities
Capital expenditures during the years ended December 31, 2011, 2010, and 2009 were approximately $237,000, $550,000 and $340,000, respectively. The years ended December 31, 2011 and 2010 included several purchases and maturities of U.S. Treasury bills.
 
Financing activities
Cash provided by financing activities was $2.6 million, $13.2 million and $26.0 million, during the years ended December 31, 2011, 2010, and 2009, respectively. During the years ended December 31, 2011, 2010 and 2009, we received proceeds of $3.9, $13.2 million and $7.4 million, respectively, from exercises of options and warrants to purchase common stock. The amount of proceeds received in the year ended December 31, 2011 was offset by the repurchase of common stock to meet minimum statutory tax withholding requirements. Furthermore, for the year ended December 31, 2010, cash receipts from exercises included proceeds under a letter agreement dated June 19, 2008 (as amended, the “Letter Agreement”) with MacAndrews & Forbes LLC (“M&F”), a related party, and for the year ended December 31, 2009, we received net proceeds of $18.6 million from a common stock offering.
 
Other
We have incurred cumulative net losses and expect to incur additional losses to perform further research and development activities. We have limited capital resources and will need additional funds to complete the development of our products. We plan to fund continued development work and operations through sources of cash that may include: collaborative agreements, strategic alliances, research grants, future equity and debt financing and procurement contracts. There is no assurance that we will be successful in obtaining additional funding on commercially reasonable terms. We believe that our existing funds combined with cash flows primarily from our procurement contract with BARDA (see Note 3) and continuing government Grants will be sufficient to support our operations for at least the next twelve months. As discussed in Item 3, "Legal Proceedings", our ability to support our operations may be adversely affected by the resolution of the pending dispute described in such section. Our success is dependent upon generating commercial sales and our ability to obtain adequate future financing. If we are unable to raise adequate capital and/or achieve profitable operations, future operations might need to be scaled back or discontinued. The financial statements do not include any adjustment relating to the recoverability of the carrying amount of recorded assets and liabilities that might result from the outcome of these uncertainties.

Item 7A. Quantitative and Qualitative Disclosures About Market Risk
 
Our investment portfolio includes cash, cash equivalents and short-term investments. Our main investment objectives are the preservation of investment capital and the maximization of after-tax returns on our investment portfolio. 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. Accordingly, we believe that, while the securities we hold are subject to 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, we are not subject to any material risks arising from changes in interest rates, foreign currency exchange rates, commodity prices, equity prices or other market changes that affect market risk sensitive instruments.

Report of Independent Registered Public Accounting Firm
 
To the Board of Directors and Stockholders of SIGA Technologies, Inc.:
 
In our opinion, the accompanying consolidated balance sheets and the related consolidated statements of operations, of changes in stockholders’ equity and of cash flows present fairly, in all material respects, the financial position of SIGA Technologies, Inc. and its subsidiary (the "Company") at December 31, 2011 and December 31, 2010, and the results of their operations and their cash flows for each of the three years in the period ended December 31, 2011 in conformity with accounting principles generally accepted in the United States of America. Also in our opinion, the Company maintained, in all material respects, effective internal control over financial reporting as of December 31, 2011, based on criteria established in Internal Control - Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO). The Company’s management is responsible for these financial statements, for maintaining effective internal control over financial reporting and for its assessment of the effectiveness of internal control over financial reporting, included in Management’s Report on Internal Control over Financial Reporting under Item 9A. Our responsibility is to express opinions on these financial statements and on the Company’s internal control over financial reporting based on our integrated audits. We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audits to obtain reasonable assurance about whether the financial statements are free of material misstatement and whether effective internal control over financial reporting was maintained in all material respects. Our audits of the financial statements included examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements, assessing the accounting principles used and significant estimates made by management, and evaluating the overall financial statement presentation. Our audit of internal control over financial reporting included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, and testing and evaluating the design and operating effectiveness of internal control based on the assessed risk. Our audits also included performing such other procedures as we considered necessary in the circumstances. We believe that our audits provide a reasonable basis for our opinions.

As discussed in Note 2 to the consolidated financial statements, effective January 1, 2009, the Company changed the way certain financial instruments that are settled in the Company’s common stock are accounted for.

A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company’s internal control over financial reporting includes those policies and procedures that (i) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (ii) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (iii) 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.

SIGA TECHNOLOGIES, INC.
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS


1. Organization and Basis of Presentation
 
Description of Business
SIGA Technologies, Inc. (“SIGA” or the “Company”) is a pharmaceutical company specializing in the development and commercialization of pharmaceutical solutions for some of the most lethal disease-causing pathogens in the world - smallpox, Ebola, dengue, Lassa fever and other dangerous viruses. The Company aims to discover, develop, manufacture and successfully commercialize drugs to prevent and treat these high-priority threats. The Company's mission is to disarm dreaded viral diseases and create robust, modern biodefense countermeasures.
 
Basis of presentation
The consolidated financial statements 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.
 
The consolidated financial statements have been prepared on a basis which assumes that the Company will continue as a going concern and which contemplates the realization of assets and the satisfaction of liabilities and commitments in the normal course of business. The Company has incurred cumulative net losses and expects to incur additional losses to perform further research and development activities. The Company has limited capital resources and will need additional funds to complete the development of its products. Management plans to fund continuing development work and operations through sources of cash that may include: collaborative agreements, strategic alliances, research grants, future equity and debt financing, procurement contracts and cash and investments on hand. There is no assurance that the Company will be successful in obtaining future financing on commercially reasonable terms. Management believes that existing funds combined with cash flows primarily from its procurement contract with the Biomedical Advance Research and Development Authority (“BARDA”) (see Note 3) and continuing government grants and contracts (collectively, Grants) will be sufficient to support its operations for at least the next twelve months. The success of the Company is dependent upon generating commercial sales and the Company’s ability to obtain adequate future financing. If the Company is unable to raise adequate capital and/or achieve profitable operations, future operations might need to be scaled back or discontinued. The financial statements do not include any adjustments relating to the recoverability of the carrying amount of recorded assets and liabilities that might result from the outcome of these uncertainties.

2. Summary of Significant Accounting Policies
 
Reclassifications
Certain reclassifications have been made to prior year amounts to conform to 2011 presentation.

Use of Estimates
The consolidated financial statements and related disclosures are prepared in conformity with accounting principles generally accepted in the United States of America. 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 revenue and expenses during the period reported. The most significant estimates include the variables used in the calculation of fair value for outstanding options and warrants granted or issued by the Company; reported amounts of revenue and expenses, impairment of goodwill, intangibles and long-lived assets, and the realization 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.
 
Cash Equivalents, Short-term Investments and Marketable Securities
The Company considers all highly liquid investments with original maturities of three months or less to be cash equivalents. Highly liquid investments with maturities greater than three months and less than one year are classified as short-term investments. Such investments are generally money market funds, bank certificates of deposit, and U.S. Treasury bills.
 
The Company classifies short-term investments and marketable securities with readily determinable fair values as “available-for-sale”. Investments in securities that are classified as available-for-sale are measured at fair market value in the balance sheet and unrealized holding gains and losses on investments are reported as a separate component of stockholders’ equity until realized.

As of December 31, 2010 the Company’s short-term investments consisted of $15.0 million of available-for-sale United States Treasury Bills. The unrealized gain relating to these investments was immaterial.

Table of Contents

 
Concentration of Credit Risk
The Company has cash in bank accounts that exceed the Federal Deposit Insurance Corporation insured limits. The Company has not experienced any losses on its cash accounts. No allowance has been provided for potential credit losses because management believes that any such losses would be minimal. The Company’s accounts payable consist of trade payables due to creditors.
 
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: 5 years for laboratory equipment; 3 years for computer equipment; and 7 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.
 
Revenue Recognition
Revenue is recognized when persuasive evidence of an arrangement exists, delivery has occurred, the fee is fixed or determinable, collectability is reasonably assured, contractual obligations have been satisfied and title and risk of loss have been transferred to the customer. The Company recognizes revenue from non-refundable up-front payments, not tied to achieving a specific performance milestone, over the period which the Company is obligated to perform services or based on the percentage of costs incurred to date, estimated costs to complete and total expected contract revenue. Payments for development activities are recognized as revenue as earned, over the period of effort. Funding for the acquisition of capital assets under cost-plus-fee Grants is evaluated for appropriate recognition as a reduction to the cost of the asset, a financing arrangement, or revenue based on the specific terms of the related grant or contract. Substantive at-risk milestone payments, which are based on achieving a specific performance milestone, are recognized as revenue when the milestone is achieved and the related payment is due, providing there is no future service obligation associated with that milestone. In situations in which the Company receives payment in advance of the performance of services, such amounts are deferred and recognized as revenue as the related services are performed.
 
For the years ended December 31, 2011, 2010, and 2009, revenues from National Institutes of Health (“NIH”) and BARDA Grants was 96%, 91% and 100%, respectively, of total revenues recognized by the Company.
 
Accounts Receivable
Accounts receivable are recorded net of provisions for doubtful accounts. At December 31, 2011 and 2010, 100% and 87%, respectively, of accounts receivables represented receivables from NIH and BARDA. An allowance for doubtful accounts is based on specific analysis of the receivables. At December 31, 2011, 2010, and 2009, the Company had no allowance for doubtful accounts.
 
Research and Development
Research and development expenses include costs directly attributable to the conduct of research and development programs, including employee related costs, materials, supplies, depreciation on and maintenance of research 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 is estimated using the Black-Scholes model. The value of the portion of the award that is ultimately expected to vest is recorded as expense over the requisite service periods in the Company’s consolidated statement of operations.
 
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 materially 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 applies the applicable authoritative guidance which prescribes a comprehensive model for the manner in which a company should recognize, measure, present and disclose in its financial statements all material uncertain tax positions that the Company has taken or expects to take on a tax return. The Company has no tax positions for which it is reasonably possible that the total amounts of unrecognized tax benefits will significantly increase or decrease within twelve months from December 31, 2011. The Company files federal income tax returns and income tax returns in various state and local tax jurisdictions. The open tax years for U.S. federal, state and local tax returns is generally 2008 - 2011; open tax years relating to unused NOLs begin in 1997. In the event that the Company concludes that it is subject to interest and/or penalties arising from uncertain tax positions, the Company will present interest and penalties as a component of income taxes. No amounts of interest or penalties were recognized in the Company’s consolidated financial statements for each of the years in the three-year period ended December 31, 2011.
 
Net Loss per Share
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 net income (loss) per share computation:

The diluted earnings per share calculation reflects the effect of the assumed exercise of outstanding warrants and the corresponding elimination of the benefit included in operating results from the change in fair value of the warrants. Diluted shares outstanding include the dilutive effect of in-the-money options and warrants, unvested restricted stock and restricted stock units. The dilutive effect of such equity awards 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 with the change in fair market value reported in the operating results of the respective period.

Fair Value of Financial Instruments
The carrying value of cash and cash equivalents, accounts payable and accrued expenses 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

45

Table of Contents

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 inputs are observable in active markets to determine the fair value of certain common stock warrants on a recurring basis and classify such warrants in Level 2. The Company utilizes the Black-Scholes model consisting of the following variables: (i) the closing price of SIGA’s common stock; (ii) the expected remaining life of the warrant; (iii) the expected volatility using a weighted-average of historical volatilities from a combination of SIGA and comparable companies; and (iv) the risk-free market rate. At December 31, 2011 and December 31, 2010, the fair value of such warrants was $622,938 and $10,524,600 classified as non-current common stock warrants on the balance sheet.

As of December 31, 2010, the Company held approximately $15.0 million in United States Treasury Bills, classified as a Level 1 security. For the years ended December 31, 2011 and 2010, SIGA did not hold any Level 3 securities.
 
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. 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 only has one reportable segment.
 
Cumulative Effect of Changes in Accounting Principles
On January 1, 2009, the Company adopted the provisions of the authoritative guidance for derivatives and hedging. The cumulative effect of the change in accounting principle recorded by the Company in connection with certain warrants to acquire shares of the Company’s common stock was recognized as an adjustment to the opening balance of accumulated deficit as summarized in the following table:

Recent Accounting Pronouncements
In September 2011, the Financial Accounting Standards Board (the “FASB”) issued updated accounting guidance, which amended guidance on how to test goodwill for impairment. This update permits an entity to first assess qualitative factors to determine whether it is more likely than not that the fair value of a reporting unit is less than its carrying amount as a basis for determining whether it is necessary to perform a two-step goodwill impairment test. The updated guidance is effective for annual impairment tests performed in fiscal years beginning after December 15, 2011 with early adoption permitted. SIGA expects that the adoption of this guidance will not have a material impact on its consolidated financial statements.

In May 2011, the FASB issued additional guidance on fair value measurements that clarifies the application of existing guidance and disclosure requirements, changes certain fair value measurement principles and requires additional disclosures about fair value measurements. The updated guidance is effective during interim and annual period beginning after December 15, 2011. SIGA expects that the adoption of this guidance will not have a material impact on its consolidated financial statements.

In January 2010, the FASB issued updated accounting guidance for fair value measurements. This update provides amendments that require new disclosure as follows: (1) A reporting entity should disclose separately the amounts of significant transfers in and out of Level 1 and Level 2 fair-value measurements and describe the reasons for the transfers. (2) In the reconciliation for fair value measurements using significant unobservable inputs (Level 3), a reporting entity should present separately information about purchases, sales, issuances, and settlements (that is, on a gross basis rather than as one net number). This update provides amendments that clarify existing disclosures as follows: (1) A reporting entity should provide fair-value measurement disclosures for each class of assets and liabilities. A class is often a subset of assets or liabilities within a line item in the statement of financial

46

Table of Contents

position. A reporting entity needs to use judgment in determining the appropriate classes of assets and liabilities. (2) A reporting entity should provide disclosures about the valuation techniques and inputs used to measure fair value for both recurring and nonrecurring fair value measurements. Those disclosures are required for fair value measurements that fall in either Level 2 or Level 3. The new disclosures and clarifications of existing disclosures are effective for interim and annual reporting periods beginning after December 15, 2009, except for the disclosures about purchases, sales, issuances, and settlements in the roll-forward of activity in Level 3 fair-value measurements. Those disclosures are effective for fiscal years beginning after December 15, 2010, and for interim periods within those fiscal years. The Company has adopted the amendments, and such adoption has not had a material impact on the consolidated financial statements.

3. Procurement Contract and Research Agreements
 
Procurement Contract

In May 2011, the Company signed the BARDA Contract pursuant to which SIGA agreed to deliver two million courses of ST-246 to the U.S. Strategic National Stockpile (the “Strategic Stockpile”). The five-year base contract award is worth approximately $435 million, and the BARDA Contract also includes various options to be exercised at BARDA’s discretion. As originally issued, the BARDA Contract included an option for the purchase of up to 12 million additional courses of ST-246; however, following a protest by a competitor of the Company, BARDA issued a contract modification on June 24, 2011 pursuant to which it deleted the option to purchase the additional courses. Under the BARDA Contract as modified, BARDA has agreed to buy from SIGA 1.7 million courses of ST-246. Additionally, SIGA will contribute to BARDA 300,000 courses manufactured using federal funds provided by the U.S. Department of Health and Human Services (“HHS”) under prior development contracts. The BARDA Contract as modified also contains options that will permit SIGA to continue its work on pediatric and geriatric versions of the drug as well as use ST-246 for smallpox prophylaxis. As described in Note 11, the amount of profits SIGA is likely to retain pursuant to the BARDA Contract is dependent upon resolution of a pending dispute.

In the fourth quarter of 2011, SIGA received approximately $41 million as advance payments under the BARDA Contract. The terms of the BARDA Contract require that the Company meets various performance conditions and delivery requirements (collectively, the "Conditions"). The advance payments are refundable if SIGA fails to fulfill the Conditions. These amounts are recorded as deferred revenue as of December 31, 2011. In accordance with generally accepted accounting principles, the Company will not be able to recognize revenue under the BARDA Contract until the Conditions have been satisfied. Direct costs incurred by the Company to fulfill the requirements under the BARDA Contract are being deferred and will be recognized as an expense as the related revenue is recognized. As of December 31, 2011, deferred direct costs under the BARDA Contract of approximately $250,000 are included in non-current other assets.

Research Agreements

The Company obtains funding from the Grants it obtains from NIH and BARDA to support its research and development activities. Currently, the Company has four active Grants with varying expiration dates through July 2016 that provide for potential future aggregate research and development funding for specific projects of approximately $25.3 million. This amount includes, among other things, options that may or may not be exercised at the U.S. government’s discretion. The Grants contain customary terms and conditions including the U.S. Government’s right to terminate a grant for convenience.
 
4. Stockholders’ Equity
 
On December 31, 2011, the Company’s authorized share capital consisted of 110,000,000 shares, of which 100,000,000 are designated common shares and 10,000,000 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.
 
2009 Financing
On December 9, 2009, the Company entered into Subscription Agreements for the sale of 2,725,339 shares of the Company’s common stock, par value $0.0001 per share, at a purchase price of $7.35 per share. Net proceeds to the Company were approximately $18.6 million.
 
2008 Financing
On June 19, 2008, SIGA entered into a letter agreement (as amended, the “Letter Agreement”) that expired on June 19, 2010, with MacAndrews & Forbes LLC (“M&F”), a related party, for M&F’s commitment to invest, at SIGA’s discretion or at M&F’s option, up to $8 million in exchange for (i) SIGA common stock and (ii) warrants to purchase 40% of the number of SIGA shares acquired by M&F. On June 18, 2010, M&F notified SIGA of its intention to exercise its right to invest $5.5 million, the remaining amount available under the Letter Agreement following earlier investments and entered into a Deferred Closing and Registration Rights

47

Table of Contents

Agreement dated as of June 18, 2010 with the Company. On July 26, 2010, upon satisfaction of certain customary closing conditions, including the expiration of the applicable waiting period pursuant to the Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended, M&F funded the $5.5 million purchase price to SIGA in exchange for the issuance of (i) 1,797,386 shares of common stock and (ii) warrants to purchase 718,954 shares of SIGA common stock at an exercise price of $3.519 per share. The number of shares issuable pursuant to the warrants granted under the Letter Agreement, as well as the exercise price of those warrants, may be subject to adjustment as a result of the effect of future equity issuances on certain anti-dilution provisions in the related warrant agreements.
 
In 2009, SIGA issued to M&F 816,993 shares of common stock and 326,797 warrants to acquire common stock in exchange for total proceeds of $2.5 million. The warrants are exercisable for a term of four years from issuance for an exercise price of $3.519 per share. The number of shares issuable pursuant to the warrants granted under the Letter Agreement, as well as the exercise price of those warrants, may be subject to adjustment as a result of the effect of future equity issuances on certain anti-dilution provisions in the warrant agreements.

In addition and in consideration for the commitment of M&F reflected in the Letter Agreement, on June 19, 2008, M&F received warrants to purchase 238,000 shares of SIGA common stock, initially exercisable at $3.06 (the “Commitment Warrants”). The number of shares issuable pursuant to the warrants granted under the Letter Agreement, as well as the exercise price of those warrants, may be subject to adjustment as a result of the effect of future equity issuances on certain anti-dilution provisions in the Letter Agreement. The Commitment Warrants are exercisable until June 19, 2012. The Company initially recorded all costs related to the Letter Agreement, including the fair value of the Commitment Warrants, as deferred transaction costs. Upon the issuance of common stock and warrants to purchase shares of common stock on April 30, 2009, the Company recorded a reduction in its additional paid-in capital for the effect of the related transaction costs.
 
The Company determined that the warrants potentially issuable to M&F under the Letter Agreement were not “indexed to the Company’s own stock” prior to their issuance in accordance with the authoritative guidance. As a result, warrants potentially issuable under the Letter Agreement met the definition of a derivative and were recorded as a liability on the Company’s balance sheet (also refer to Cumulative Effect of Changes in Accounting Principle in Note 2). Management determined that, upon issuance, the warrants do not meet the definition of a derivative and, consequently, the warrants are reflected as equity at December 31, 2010. The Company recorded a loss of $1.1 million for the year ended December 31, 2010 representing the increase in the fair value of the warrants from January 1, 2010 through the date of issuance.
 
2006 and 2005 Placements
In 2006 and 2005 the Company sold shares of its common stock and warrants to purchase shares of common stock. In 2006, the Company issued 1,000,000 warrants with an initial exercise price of $4.99 per share (the “2006 Warrants”). In 2005, the Company issued 1,000,000 warrants with an initial exercise price of $1.18 per share (the “2005 Warrants”). As of December 31, 2010, all of the 2005 Warrants have been exercised and issued. The 2006 Warrants may be exercised through and including October 19, 2013. Due to the effect of certain anti-dilution provisions in such warrants, the Company adjusted the number of shares issuable under the 2006 Warrants by 706,302 through December 31, 2011. The exercise prices of the warrants issued in these placements were also adjusted. At December 31, 2011, 815,568 of the 2006 Warrants at an exercise price of $2.92 were outstanding. The number of shares issuable pursuant to the Warrants may be subject to further adjustment as a result of the effect of future equity issuances on anti-dilution provisions in the related warrant agreements.
 
The Company accounted for the 2006 and 2005 Warrants in accordance with the authoritative guidance which requires that free-standing derivative financial instruments that require net cash settlement 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. At December 31, 2011, the fair market value of the 2006 Warrants was $623,000. The Company applied the Black-Scholes model to calculate the fair values of the respective derivative instruments using the contractual term of the warrants. Management estimates the expected volatility using a combination of the Company’s historical volatility and the volatility of a group of comparable companies. For the year ended December 31, 2011, the Company recorded a gain of $8.9 million as a result of a net decrease in fair value in the 2006 Warrants.

6. Stock Compensation Plans
 
In May 2010, the Company adopted its 2010 Stock Incentive Plan (the “2010 Plan”), as amended in February 2012, to supersede its 1996 Incentive and Non-Qualified Stock Option Plan (the “1996 Plan”). The 2010 Plan provides for the granting of up to 2,000,000 shares of the Company’s common stock to employees, consultants and outside directors of the Company. The awards that may be provided under the 2010 Plan include: incentive stock options (“ISOs”); nonqualified stock options; stock appreciation rights; restricted stock units; shares of restricted stock; and shares of unrestricted stock.
 
Stock option awards provide holders the right to purchase shares of Common Stock at prices determined by the Compensation Committee but 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 vesting period for options granted under the 2010 Plan, except those granted to outside directors, is determined by the Compensation Committee of the Board of Directors. The Compensation Committee also determines the expiration date of each equity award, however, ISOs may not be exercisable more than ten years after the date of grant. The maximum term of equity awards issued under the 2010 Plan is ten years.

The fair value of option grants were estimated at the date of grant during the years ended December 31, 2011, 2010, and 2009 based upon the following weighted average assumptions:

Expected volatility has been estimated using a combination of the Company’s historical volatility and the historical volatility of a group of comparable companies, 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.
 
For the years ended December 31, 2011, 2010, and 2009, the Company recorded compensation expense of $12.5 million, $1.5 million and $2.1 million, respectively, related to employees and directors equity awards. The total fair value of stock options vested during each year was $2.5 million, $1.5 million and $1.4 million for 2011, 2010 and 2009, respectively. The total fair value of restricted stock and restricted stock units vested during the year-ended December 31, 2011 was $10.0 million; there were no grants of restricted stock or restricted stock units in previous years. The weighted-average grant-date fair value of awards granted was $11.70, $4.95 and $4.29 for 2011, 2010 and 2009, respectively.

As of December 31, 2011, we generated federal net operating loss carryforwards of $90.6 million to offset future taxable income. In 2011, approximately $0.9 million of previously available NOLs expired and approximately $1.2 million expires in 2012 if not utilized, with the remainder expiring in various years between 2018 and 2031. As a result of a previous change in stock ownership, the annual utilization of the net operating loss carryforwards for years prior to 2004 may be subject to limitation. In addition, we have $700,000 of federal net operating loss carryforwards attributable to the excess tax deductions on stock option activity that will be realized as a benefit to Additional Paid-in Capital when they reduce income taxes payable.
 
The recognition of a valuation allowance for deferred taxes requires management to make estimates and judgments about the

Table of Contents

Company’s future profitability which are inherently uncertain. Deferred tax assets are reduced by a valuation allowance when, in the opinion of management, it is more likely than not that some portion or all of the deferred tax assets will not be realized.
During the year ended December 31, 2011, the Company recorded an income tax benefit of $36.0 million primarily due to a partial reduction of its valuation allowance as a significant portion of its deferred tax assets became realizable on a more-likely-than-not basis as a result of the execution of the BARDA Contract and the resulting forecasts of pre-tax earnings. The Company maintains a valuation allowance of $4.6 million with respect to certain net operating losses and other deferred tax assets which may expire prior to realization. If the current estimates of future taxable income are reduced or not realized, for example, based on the ultimate outcome of the pending dispute described in Note 11, the Company’s assessment regarding the realization of deferred tax assets could change. Future changes in the estimated amount of deferred taxes expected to be realized will be reflected in the Company’s financial statements in the period the estimate is changed with a corresponding adjustment to operating results. Changes in estimates may occur often and can have a significant favorable or unfavorable impact on the Company’s operating results from period to period.

For the years ended December 31, 2011 and 2010, the Company’s effective tax rate differs from the federal statutory rate principally due to the partial reversal of its valuation allowance, net operating losses and other differences for which no benefit was recorded, state taxes and other permanent differences. For all years presented, the current year provision was not material.
 
Other Income, net, for the year ended December 31, 2010, includes $648,000 awarded to the Company under the U.S. Government’s Qualified Discovery Tax Credit program.
 
11. Commitments and Contingencies
 
Operating lease commitments
 
The Company leases its Corvallis, Oregon, facilities and office space under an operating lease which was amended in 2011 and expires in 2017. This lease contains annual escalation clauses, renewal provisions and generally requires us to pay utilities, insurance, taxes and other operating expenses. Future minimum rental commitments under non-cancelable operating leases as of December 31, 2011 are expected to be as follows:

In December 2006, PharmAthene, Inc. (“PharmAthene”) filed an action against us in the Delaware Court of Chancery captioned PharmAthene, Inc. v. SIGA Technologies, Inc., C.A. No. 2627-N. In its amended complaint, PharmAthene asks the Court to demand SIGA enter into a license agreement with PharmAthene with respect to ST-246, as well as issue a declaration that SIGA is obliged to execute such a license agreement, and award damages resulting from SIGA’s supposed breach of that obligation. PharmAthene also alleges that SIGA breached an obligation to negotiate such a license agreement in good faith, as well as seeks damages for promissory estoppel and unjust enrichment based on supposed information, capital and assistance that PharmAthene allegedly provided to SIGA during the negotiation process. A trial was held on PharmAthene’s claims in January 2011.

In September 2011, the Court of Chancery issued its post-trial opinion. The Court denied PharmAthene’s requests for specific performance and expectation damages measured by the present value of estimated future profits. However, the Court held that SIGA breached its duty to negotiate in good faith and was liable under the doctrine of promissory estoppel. The Court consequently awarded to PharmAthene what the Court described as an equitable payment stream or equitable lien consisting of fifty percent of the net profits that SIGA achieves from sales of ST-246 after SIGA secures the first $40 million in net profits, for ten years following the first commercial sale. In addition, PharmAthene was awarded one-third of its reasonable attorney fees and expert witness expenses. Based on certain documents provided to the Court by PharmAthene in January 2012, SIGA recorded a loss contingency of approximately $2.0 million for such attorney fees and expert witness expenses as part of its accrued expenses as of December 31, 2011. The difference between the amount accrued and PharmAthene’s request for $2.7 million relates to amounts currently in dispute.
SIGA filed a motion for reargument in October 2011, requesting that the Court vacate its award of an equitable payment stream or equitable lien. In December 2011, the Court denied SIGA’s motion.
The timing and amount of payments to be made pursuant to the Court’s September 2011 ruling remain uncertain. Determination of these matters requires both clarification as to the application of the Court’s post-trial ruling and the timing and amount of payments to SIGA for sales of ST-246. Thus, the Company is unable to estimate a range of loss that may result from implementation of the Court’s post-trial ruling with respect to ST-246 sales, although this ruling is likely to have a materially adverse impact unless the Company is successful in any subsequent appeal of the Court’s final judgment. The Company cannot assure the success of any such appeal.

From time to time, the Company is involved in disputes or legal proceedings arising in the ordinary course of business. The Company believes that there is no dispute or litigation pending, except as discussed above, that could have, individually or in the aggregate, a material adverse effect on its financial position, results of operations or cash flows.

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, 2011. The term “disclosure controls and procedures” is defined in Rules 13a-15(e) and 15d-15(e) under the Securities and 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 Office and Chief Financial Officer have concluded that, our disclosure controls and procedures were effective as of December 31, 2011 at a reasonable level of assurance.
 
     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 and Exchange Act of 1934. 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 prepared for external purposes in accordance with generally accepted accounting principles. Our internal control over financial reporting includes those policies and procedures that:
 
a.
pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and disposition of the Company’s assets;

b.
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

c.
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, including our Chief Executive Officer and Chief Financial Officer, conducted an evaluation of the effectiveness of the Company’s internal control over financial reporting as of December 31, 2011. In making this evaluation, management used the criteria set forth by the Committee of Sponsoring Organizations of the Treadway Commission (the “COSO”) in Internal Control-Integrated Framework. 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, 2011.
 
The effectiveness of our internal control over financial reporting as of December 31, 2011 has been audited by PricewaterhouseCoopers LLP, an independent registered public accounting firm, as stated in their report which appears herein.   
   
     Changes in Internal Control over Financial Reporting
 
There has been no changes in our internal control over financial reporting during the quarter ended December 31, 2011 that materially affected, or are reasonably likely to materially affect our internal control over financial reporting.
