golfyeti...based on your post can you work out a share price/market cap for fun? Say use 20-25 P/E ratio. Not sure what the "gross margin" would be for bio for a $5-6Bil gross revenue.  

"$6 billion in your example is an annual revenue, not a market cap.  It is probably more meaningful to estimate derived earnings from that revene amount (you'll need to estimate gross margins) and then if you use a typical biotech 'price to earnings' ratio (P/E) you can then convert that estimated annual earnings amount into an estimated market cap.  Then divide that market cap by 200M shares to get a price per share.  (I use 250M to be more conservative)."
