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.
