Systematics Incorporated was a data processing company acquired in 1968 by Arkansas superinvestor Jackson T. Stephens. In 1990 it was sold to Alltel Corporation, and today is a part of Fidelity Information Systems.
Fidelity Information Systems still uses the name 'Systematics' as the name of a retail banking software product suite.
Systematics employees have held two reunions, most recently the 40th Anniversary Reunion in 2008. Pictures from both reunions and current information about former employees were available for a while at the website “www.sireunion.org,” which no longer exists.
