FireEye, which provides virtual machine-based IT security software to enterprises and government, raised $303.5 million on Thursday by offering 15.2 million shares (all primary) at $20, above the upwardly revised range of $15 to $17. The company had originally filed to offer 14.0 million shares at a range of $12 to $14 before boosting the range to $15 to $17 in an amendment filed with the SEC on Tuesday. FireEye, which initially filed confidentially on 5/14/2013, will list on the NASDAQ under the symbol "FEYE". Morgan Stanley, Goldman Sachs and J.P. Morgan acted as lead managers on the deal, which was one of nine IPOs to be completed this week.
