America’s fabled Budweiser beer empire could be swallowed by a giant European brewer in a $46.4 billion cash deal.

Shares of Bud’s parent, Anheuser-Busch, surged nearly 10 percent just minutes after news of the evolving deal swept through Wall Street during its closing minutes of trading and in after-market trades.

Belgium’s huge global brewer InBev NV, the maker of Beck’s and Stella, said it offered an unsolicited $65 a share for Anheuser-Busch, whose board said it was reviewing the planned takeover – which would be the industry’s biggest.

The family-dominated Anheuser-Busch, if it decides to fight or seek more money, would be pitted against the world’s largest beer maker by sales, which could exert wide pressure through its broad reach on world markets.
