CHAR is majority owned by a company that has agreed to be bought out on the cheap. Thus there has been concern that the buyer will use their majority shareholder status to take CHAR private, that is, offer a cheap buyout price per share that is less than their excellent earnings might otherwise demand. In other words, since CHAR is already majority owned, CHAR can be owned outright (taken private) for a steal.
