Anheuser-Busch InBev, the world's biggest brewer, is close to buying the remainder of Mexico's Grupo Modelo for more than US$12 billion ($15.2 billion), according to a person with knowledge of the matter.
The purchase may be announced as soon as this week, said the person, who asked not to be identified as the discussions are confidential.
The deal isn't completed and may still fall through, the person said.
AB InBev, the Belgium-based maker of Bud Lite, has a non-controlling 50 per cent share of Corona owner Modelo that it inherited after InBev bought US brewer Anheuser-Busch in 2008 for US$52 billion, the biggest brewing deal ever.
Brewers are among consumer-goods companies looking to expand outside Europe as high unemployment and sluggish economies hold back growth.
