zoomlik, not sure what is going on behind the scenes but nothing has been filed with the SEC to this point. There is no immediate need for funds (they ended last year with about $15M in cash) but it would be in their best interests to raise some money fairly soon, to pay off their senior debt, which is costing them a lot of money interest.
I'm thinking they are waiting until 1Q numbers come out at this point since the numbers will probably be very good and will cause them to raise 2018 guidance.
I still think there is a chance they could get some analyst coverage pretty soon, the only question is whether it will be before 1Q gets announced or right after it.
