Commenting on the transaction, Neil Carson, chief executive of Johnson Matthey said, "The acquisition of Applied Utility Systems is a further step in our strategy of making bolt-on acquisitions in our core business area of environmental technologies. It will enhance the capability of our Stationary Emissions Control business to serve a greater range of applications for controlling harmful NOx emissions."
