That depends on how you define "losing money." You can have a net loss as a result of a big one-time charge (a non-cash charge similar to the ones you see in the airline business every quarter). What really counts is cash.
I haven't seen the cash flow statement - what were the net cash flows? What is the trend? If Avantair is adding debt to sustain operations, are they able to pay the additional interest payments (debt service in general). Cash is king. It's true that Avantair is a public company and earnings is always emphasized in that case, but cash is what people should always be focusing on. In this time of frozen bank credit, internal cash flow becomes even more critical. Does cash inflow match or exceed cash outflow? Again, what's the trend? Those are the questions I would be asking as a shareholder.
Good points.
