Without question one of the more interesting drinks companies to watch over the past few years has been Molson Coors. From the 14% drop in sales posted in 2015 to the boost provided by the acquisition of the 58% of MillerCoors it didn't already own in 2016, from the surprisingly-high cost savings of US$200m in 2017, to the loss in share price value of 21% during the same year, the past half-decade has been nothing short of a rollercoaster for the world's third-largest brewer by value and fifth-largest by volume.
