Informactica Corp. has received offers from two private equity firms and is in talks over a sale that could value the enterprise software company between $5 billion and $6 billion. Private equity firms have been cautious to talk big companies private over fear of overpaying. Permira Advisers Ltd along with Canada Pension Plan Investment Board, and Thoma Bravo LLC, in partnership with Ontario Teachers’ Pension Plan, all submitted bids for Informatica and they have been asked to improve their offers. A third group of firms comprising of Silver Lake Partners LP and Hellman & Friedman LLC did not submit a firm offer but has informed Informactica that they are open to continuing talks if its valuation expectations are lowered. Informactica helps companies connect software and enterprise applications and stores data. In 2014 the firm total revenue rose 10.5% year to year to $1.05 billion.
