Unisys (NYSE: UIS) rose 20 percent Monday after the company refused comment Sunday on a German magazine's report that Deutsche Telekom AG was seeking to buy the U.S. information services company.
Shares were up 4 7/16 to 29 3/4 Monday. The company's stock has fizzled since it reported flat sales along with its fourth-quarter earnings.
"We have a responsibility to shareholders to evaluate any offer that could be made for the company," said Unisys spokesman Brian Daly, who added this was a broad statement of the company's policy. "That does not mean we are seeking these opportunities."
Germany's Deutsche Telekom AG also declined comment Monday.
"We don't comment on speculation," Telekom chief financial officer Karl-Gerhard Eick said in response to a report in German magazine Focus at the weekend, which said Telekom was poised to add Unisys to its IT division.
Unisys already has a network services agreement with Deutsche Telekom, which was announced in December.
