Even where it is trading right this minute, $52.08, I think it is an incredible bargain. Based on the most recent quarter, free cash flow is annualized around $450M. So the company is trading in the vicinity of 15x fcf. It really should trade for at least 20x, given if nothing else that it has strong recurring revenue. When you factor in management's ability to acquire and control costs, it should probably trade at more of a growth multiple, likely 25-30x.
