Private equity firms are said to be interested in Informa, the publishing and events giant. Timesonline.co.uk reports that PE firms Apax and Carlyle are said to be interested in acquiring the company, which is currently has a market capitalisation of £1.64 billion. At this time, however, neither company has approached Informa. Analysts are mixed on the company’s performance, with some concerned that its £502 million Datamonitor acquisition last year had saddled it with high debt levels, while others believed it is holding up well in market conditions. In February, Informa reported strong full year results, and positive forecast for the rest of the year.
