Anheuser-Busch InBev won U.S. antitrust approval for its takeover of SABMiller after the maker of Budweiser agreed to give up ownership of the Miller brand and open the door to greater competition from craft beers. AB InBev will sell SABMiller’s stake in MillerCoors, separating the two brands, and refrain from practices that restrict distribution of smaller rival brews, thus protecting the ability of craft and import beers to compete, the Justice Department said in a statement Wednesday.
