That's far too many employees for the results/revenue.
Two sites means nothing.
Customers means very little, because they obviously can produce a product, which is in routine demand by all types of companies.
The only question is: can they do what they can claim they can do, as well as they claim?
So far, the machines have way more capacity that they are able to use, it seems. Or the machines are breaking down and not working right, just about all the time.
I see a company that claimed to be ready to make money years ago. And yet they still operate in development phase, practically speaking.
The proof is in the pudding, or in this case, revenue. It's WAY off from what they should have produced by now. There is no logical excuse that justifies this failure, not even petcoke.
