Carlyle telecom Acquisitions

Carlyle Group, the world's second-largest private-equity firm, agreed to pay about $2.6 billion to take Syniverse Holdings Inc. private, its second telecommunications buyout in as many days.

Carlyle is offering investors $31 a share in cash, Syniverse said. That's a 30 percent premium to Wednesday's closing price for the Tampa-based company, which makes mobile-phone messaging and network technology. The telecommunications-gear industry, where many companies were hit with spending cuts amid the global recession last year, is rebounding as demand for mobile data services and network equipment increases.

Carlyle also agreed to pay $3.9 billion for fiber-optic cable maker CommScope Inc. to take advantage of demand for high-speed networks.

Private-equity firms are attracted to the industry because of the "explosive, accelerating usage of mobile Internet devices," said John Bright, an analyst with Avondale Partners in Nashville, who rates Syniverse shares "market perform" and doesn't own any.
