"As discussed in Note 2 to the financial statements, the Company's negative cash flow from operations and losses from operations raises substantial doubt about its ability to continue as a going concern."
Quoted from the filing. Source
The filing states that substantial doubt exists about the company's ability to continue as a going concern: it may not have enough cash to last the next 12 months. Expect dilution, debt deals or worse. An auditor's going-concern paragraph is the strongest form of this warning.
