Shares in Anheuser-Busch rose to a four-month high on the back of new bid speculation about a potential tie-up with InBev. The US brewer of Budweiser and Bud Light saw its shares increase to $52.75 (£26.66) on Wednesday after Belgian traders bought the possibility of a merger with InBev, the maker of Stella Artois and Beck’s, back into the spotlight. The rumours came as Molson Coors was expected to get approval to merge its US operations with those of SABMiller, creating a stronger competitor to Anheuser-Busch, which is the current US market leader. Anheuser-Busch has profit margins of nearly 17%, which is nearly double those of Coors or Miller.
