Rowntree Mackintosh Confectionery was a British company formed by the merger of Rowntree's and John Mackintosh Co. The company was famous for making chocolate brands, such as Kit Kat, Aero and Quality Street. It was purchased by Nestlé in 1988, with products rebranded under its own brand. Rowntree Mackintosh Confectionery owned Mackintosh's former Halifax headquarters and factory. The factory is still in use, located next to Halifax railway station, for production of Quality Street and other confections.
