Personally starting to get concerned. Claiming profitable business but not much cash to show for it so far.
Has anyone spoken to management recently? Everything is all upbeat re shipping loads and revenues going up etc but cash receipts stagnating (not including the $800k coming). On the surface it looks like great expansion happening but revenues for the dec quarter were over $1m but cash received for all three quarters is under $900k, something has to give and I am hoping it is a significant increase in cash coming in and not to get stuck into another “just wait till next quarter scinario”.
I think an email or phone call is on the cards unless someone here can provide some clarity.
