Yes, they (presumably the Winthers plus maybe Justin Moreno plus whoever else they'd add to their ownership group) would take out all (or maybe it's just most - enough taken out so that SEC reporting drops out)the other shareholders via a solicitation/tender offer.
...Michael Dell used his own money and that of a venture capital firm to buy out the other Dell shareholders.
The question is whether the Winthers have either a spare million dollars or two lying around and/or whether they've got a venture capital firm ready to put up what they don't have. The overall theme is that SEC compliance is costing the company a lot of money, I would think, and that the company would be profitable faster if it weren't burdened with public shareholders.
I'm sure others on this board could give better/simpler responses to your question, as my entire career was in the not-for-profit sector. But I think I've got the general theme here correct.
