Before I clicked any of those links posted by the OP, I went to the SEC's site and downloaded the latest 8-K.
Right away, I am seeing a book value of ($1.56B). The net debt is $2.3B!
Even though they are cash flow positive, it will take them a heck of a long time (and good luck) to get out of the hole. What am I missing in this, admittedly quick, back of the envelope, analysis?
