Unisys' chief executive Lawrence Weinbach described 1997 as a "much improved year" following a 225 per cent increase in net profits, although final results were hit by a massive $1.1 billion charge.
Before one-time charges, Unisys reported $199 million profit on revenue of $6.64 billion - the former figure boosted by a significant contribution from a strong fourth quarter of $86.9 million.
Fourth quarter revenue grew by five per cent in this quarter to $1.9 billion, driven by business growth from Unisys' services offerings, helping to offset a six per cent decline in hardware sales.
A one-time charge of $1.1 billion, mostly related to the 1986 merger of Burroughs and Sperry that created Unisys, meant the year actually resulted in a loss of $853 million.
"Driven by continued strong shipments of our Clearpath enterprise servers and a turnaround to operating profitability in our Information Services group, we achieved the best quarterly operating margin in more than three years," said Weinbach.
Last week Unisys announced it would cease manufacturing PCs and select another manufacturer to provide PCs under the Unisys brand.
