Not sure I agree that ONT has not been able to achieve sustained growth. The past 12 months have been impacted by the loss of CDDS funding however this year should see a return to good growth, particularly after including their large Brisbane based acquisition in May 2014. I see consensus FY15 for ONT sits at 28.6cps which looks achievable. That would have them delivering 12.5% pa EPS growth for 10 years as a listed company. PSQ can't claim that sort of record yet. Big difference between what you achieve unlisted vs the pressure of being listed and having to meet expectations year in year out.
PSQ's performance has prompted me to take another look at ONT, in fact I have bought a small parcel. Kicking myself I was a day too late placing my PSQ bid!
