IWG can keep expanding into new product lines as they did when they bought the water heater line. They can also expand from business jets to commercial airlines. In essence they can leverage their business structure into markets multiple the size they are currently in. They've pretty much dominated their water treatment nich for business jets for a long time so that may only grow with the market. It is expansion into new product lines and into commercial jets where the big payoff could be. With its cash position, and unused debt capacity, and cashflow it has the money for acquistions and investments.
