AB InBev became the world's largest brewer after acquiring Anheuser-Busch in 2008.
Anheuser-Busch InBev, commonly shortened to AB InBev, is a Belgian multinational brewing company. Its modern structure grew from a series of mergers, including Interbrew's combination with AmBev in 2004 and the purchase of Anheuser-Busch in 2008.
The transaction brought brands such as Budweiser and Bud Light into the same global group as Stella Artois, Beck's, and Brahma. In 2016, AB InBev completed its acquisition of SABMiller, further expanding its international reach.
AB InBev is distinct from Heineken, which remains an independent Dutch brewing company. The brewer is publicly listed in Brussels, and its market capitalization varies with the share price and business conditions.
