Science Applications International, based in San Diego, is the largest privately held defense contractor for scientific, engineering, systems integration and technical services to the U.S. Government and commercial markets. It has many offerings but generally focuses on security, intelligence and homeland defense.

The company also filed for a capital restructuring and will create a parent company called SAIC Inc., with its current shareholders becoming shareholders of the parent company. Given the restructuring and size of the initial offering, SAIC does not expect the IPO to finalize until 2006.
