RE:Montney not Cardium Thanks for the correction, I got it mixed up with Transglobe.
You are right about the production being mostly heavy oil, but the production growth will be coming from light oil, which will reach 7000 BOED based on guidance. If oil stays above $50, that should have the company trading at about 8X future cash flow, in addition to VERY LOW EV/2P (<$1 per barrel) and EV/BOED ($29400) ratios.
The heavy oil assets provide product leverage while the balance sheet of the company is not as stretched as some of the other names e.g. MEG BTE. If oils stays around $50 for the next few years, ATH will be just fine. But if oil takes off to $60, the company will do very well.
