you multiply the EPS of .13 x the PE multiple. Given SLB's PE is 20 and is a much much much more developed company, i would defiantely argue that DPDW should command a much higher PE (given it has a much greater chance of growth, espically thru acquisitons), espically once/if it gets listed on the AMEX.
All in all, once were on the AMEX i say a PE of 30 should be pretty fair, but higher depending on the factors that are coming out of the company. Major factors will be how fast the company is growing and the type of margins they are setting force.
Keep in mind, this company is very unique for many institutional traders who look to lock up a peice of a deepwater oil services company that is up and coming and some may not care about giving a PE of 30/40 as long as they get a peice of the company once it gets onto the AMEX.
all just my opinion, but .13 EPS is HUGE with a capital H imo
