Company Description

SIGA Technologies, Inc. (NASDAQ: SIGA) is a commercial-stage pharmaceutical company in the pharmaceutical preparation manufacturing industry. According to the company’s public disclosures, SIGA focuses on global health and the development of medicines to treat and prevent infectious diseases, with a primary emphasis on orthopoxviruses.

The company describes itself as being dedicated to protecting humanity against severe infectious diseases that occur naturally, accidentally, or intentionally. SIGA highlights its work with governments and public health agencies to provide medical countermeasures against global health threats. The company’s business is centered on the development and commercialization of antiviral therapies that address these high-consequence pathogens.

Core product focus: TPOXX (tecovirimat)

SIGA’s flagship product is TPOXX (tecovirimat), an antiviral medicine. Based on the company’s statements in its press releases, TPOXX is:

  • Approved in the United States and Canada for the treatment of smallpox.
  • Authorized in Europe, the United Kingdom, and Japan for the treatment of smallpox, mpox (monkeypox), cowpox, and complications following smallpox vaccination (vaccinia complications).

In Japan, the company notes that the product is approved under the name TEPOXX for the treatment of smallpox, mpox, cowpox, and complications following smallpox vaccination in adults and pediatric patients weighing at least 13 kg. SIGA further states that TEPOXX is the first antiviral therapy approved by the Pharmaceuticals and Medical Devices Agency (PDMA), in collaboration with the Japan Ministry of Health, Labour and Welfare, for the treatment of orthopoxviruses.

Business model and health security focus

The company characterizes itself as operating in the health security and biodefense space. Public information indicates that SIGA generates product revenues from sales of oral and intravenous (IV) formulations of TPOXX. The company reports product sales and supportive services as part of its revenues, and also reports research and development revenues.

From its financial disclosures and press releases, SIGA indicates that a significant portion of its product sales are related to deliveries of oral and IV TPOXX to the U.S. Strategic National Stockpile (SNS) and to the U.S. Department of Defense, as well as international customers. The company has reported procurement orders and deliveries of TPOXX to the SNS and has noted international sales to multiple countries over recent years.

SIGA also reports that it receives development funding under a contract with the U.S. Biomedical Advanced Research and Development Authority (BARDA), referred to in company disclosures as the BARDA 19C contract. The company has described modifications to this contract that add funding for a TPOXX pediatric development program and for manufacturing-related activities.

Government and international partnerships

In its public statements, SIGA emphasizes partnerships with governments and public health agencies. The company notes a long track record as a partner to the U.S. Government and mentions working with international governments as part of its health security mission. Over a multi-year period, SIGA has reported procurement orders for oral TPOXX from numerous countries and has highlighted international sales in different regions, including an example of a sale in Africa in response to a request from a national ministry of health.

These relationships are central to SIGA’s role in biodefense and health security, as the company positions TPOXX as an essential countermeasure against orthopoxvirus-related threats. The company’s disclosures also reference the broader international biodefense market and the importance of regulatory approvals in multiple jurisdictions.
