U.S. management, overhauled in late 2017, believes it is on course to rebound in the company's biggest market. Part of that is the local-ad focus and fresh versions of 143-year-old staple Budweiser, as well as Bud Light available now in an orange flavor. The two main brands make up 56 percent of its U.S. beer sales, according to market research company Euromonitor International. That is down from more than 60 percent in 2013. Whitworth, a former Marine, CIA officer and PepsiCo Inc director, said the goal is to boost the brand's shares and eventually halt their sales decline. AB InBev has a 36.4 percent share of the U.S. beer market, according to Euromonitor, followed by Molson Coors and Constellation Brands. In general, mainstream lagers including Bud and Bud Light have fallen, while the shares of craft and imports have risen, according to market research group Nielsen. Drinkers have also shifted to wine and spirits.
