Anheuser-Busch InBev SA/NV (abbreviated as AB InBev) is a multinational drink and brewing holdings company based in Leuven, Belgium.[3][4][5] Additional main offices are located in São Paulo, New York City, London, St. Louis, Mexico City, Bremen, Johannesburg and others.[6] The company was enlarged in October 2016 when AB InBev purchased SABMiller and concluded a merger of the two entities. It has been the world's largest brewer even before the acquisition of SABMiller and is considered one of the largest fast-moving consumer goods (FMCG) companies in the world. The annual sales for the company in 2018 were US$54.6 billion;[1] prior to the merger, ABInBev had realized US$45.5 billion in revenue in 2016. The company is expected to have a 28 percent market share of global volume beer sales in 2017, according to Euromonitor International.[7]

AB InBev was formed through InBev (itself a merger between Interbrew from Belgium and AmBev from Brazil) acquiring Anheuser-Busch from the United States.[8] In October 2015, Anheuser-Busch InBev announced a successful all-cash bid to acquire multinational competitor SABMiller for £69 billion (US$107 billion). Shareholders for both companies approved the merger on 28 September 2016. The deal closed on 10 October 2016. The new entity has approximately 500 beer brands in over 100 countries.[2]

SABMiller ceased trading on global stock markets. The company subsequently sold the former SABMiller's interest in MillerCoors to Molson Coors, sold many of the former SABMiller's European brands to Asahi Breweries and sold much of its Coca-Cola bottling and distribution interests to the Coca-Cola Company.[9][10][11][12]
