You are just factoring in ABSSSI at this point. B-OM, Diabetic foot, eye, ear, proshtetic joint and other biofilm applications, cystic fibrosis,GI, animal health/food supply...I can't venture a guess, but $1B revenue is waaayyy too low.
When deriving the pps from the market cap you have to factor in the options and warrants. I got 150.5 mil fully diluted. Someone else posted 160 on this board. So approximately $31 -$33 pps per $5B in market cap. And we are just talking Bril here!
