After a month-long battle, brewers Anheuser-Busch Cos. Inc. and InBev SA announced early Monday they have agreed to merge in a $52 billion deal.

Ending more than a century and a half of independence, St. Louis-based Anheuser-Busch agreed to a $70-per-share offer from InBev. The Leuven, Belgium-based maker of Stella Artois and Beck’s won its target over after adding $5 to the $65-per-share offer it made on June 11.
