Unisys is an American information technology company formed in 1986 by the merger of Burroughs and Sperry, two of the earliest computer manufacturers, and it still supports the ClearPath mainframe line descended from those machines. Its modern business is built around digital workplace services, cloud and infrastructure management, application modernisation and a logistics software business, sold largely to government agencies, banks, airlines and transport operators that run long-lived critical systems. Headquartered in Blue Bell, Pennsylvania and listed on the New York Stock Exchange, it carries a substantial legacy pension obligation alongside its services operations.
