The "going concern" language is nothing new in 10Q or 10K filings, I wouldn't be to worried about the company going out of business, I don't think Wexford would let that happen, they own over 44% of the company. Either revenues continue rising and the company goes cash flow positive eventually, or the company will have to offer a small block of shares up for sale to keep the lights on while waiting out the FDA, like they have done for 13 years. The company has managed to not take on debt or massively dilute the share holder with the over $90 million they have raised over 13 years, no reason to believe that would change any with the exact same people still sitting on the BOD. The company has plenty of value in it's current products and large patent portfolio.
