If the stock is suppressed, then there is no option available for the management or the board. Management is doing everything right. They made money, good eps, decent revenue, stock buyback. Still if the streent dont value them properly, then take t private or sell it. It is upto street to value the company properly.
A company can't be taken private until 50.1% of the common stock is purchased by the parties proposing to privatize it. If they do not offer the common stock holders a price that is high enough to induce a controlling interest to sell, then the privitization cannot take place.
