No doubt they would prefer to be private, but they just did an investor presentation and slide deck in October, so it seems like they are making a bit of an effort. Bottom line, they just don't have great news to report right now and until those things materialize and flow through the income statement, I don't think we'll see a lot of movement in the stock.
Also, pretty sure the board owns only 23% or so of the voting power, correct me if I'm wrong.
