NEW YORK, Oct. 23, 2008 (GLOBE NEWSWIRE) -- SIGA Technologies, Inc. (Nasdaq:SIGA), a company specializing in the development of pharmaceutical agents to fight bio-warfare pathogens, today announced that it has been selected as a winner of the Deloitte New York, New Jersey, Connecticut Technology Fast 50 Program for 2008.

The regional award, which recognizes the 50 fastest growing technology, media, telecommunications and life sciences companies in the Tri-State area, based on percentage revenue growth over five years, ranked SIGA as 44 on the list. The award was presented to the company on October 22 at the Metropolitan Club in New York City.

The Fast 50 is an annual election of the 50 fastest growing technology companies. The selection will be based on the percentage revenue growth over the past five years (2003 to 2007). Participants may come from the public and private sector technology and include all segments including software, Internet, biotech/life sciences, computers/peripherals, semiconductors, communications/networking and media/entertainment.

SIGA's revenues have come in the form of grants and contracts from the government that support the research and development of the company's product pipeline, most importantly its lead product candidate, ST-246, an antiviral for orthopox viruses. Over recent years, the government has increased its support for SIGA's products, as ST-246 and other drug candidates have continued to move through the development pipeline. In recent weeks, the government has provided additional support to SIGA in the form of four contracts totaling approximately $80 million.

Commenting on the award, Dr. Eric A. Rose, SIGA's Chairman and Chief Executive Officer, stated, "This recognition speaks to the continued support that the government has provided in our efforts to develop a pipeline of products to protect and defend against the threat of bio-warfare. We will use the more recent monetary contributions from the government to further our product pipeline, most notably our lead product candidate, ST-246."
