NEW DELHI -- Anheuser-Busch InBev has agreed to buy its main rival SABMiller for £68 billion ($104 billion), creating a super brewery with sales of $55 billion.
The combined firm will be the world's largest beermaker by far, with nine of the world's top 20 beers by volume.
AB InBev will offer most SABMiller shareholders £44 ($67.59) per share for the maker of Miller Lite, Pilsner Urquell and Peroni, a premium of roughly 50% over the share price before acquisition rumors started flying.
The companies described the agreement, which must be approved by regulators, as a "possible deal." SABMiller's board members have indicated they will recommend the offer to shareholders. If the deal falls apart, AB InBev will pay a $3 billion penalty to SABMiller.
If completed, it would be the biggest beer deal ever and among the top five acquisitions of all time.
SABMiller had been playing hard to get. The brewer turned down at least four previous offers from AB InBev -- its first approach was worth £38 ($58) a share. SABMiller shares jumped 8.5% to £39.30, while AB InBev shares gained 1.8% to 100 euros.
Antitrust regulators are likely to put the deal under a microscope. The concern is that the combined company would wield too much power in key markets, resulting in higher beer prices for consumers.
In order to get the merger past the the U.S. Department of Justice, the firms could be forced to sell some of their assets in the country, including SABMiller's stake in the MillerCoors joint venture.
Regulators similarly compelled AB InBev to shed some of its ventures following its bid for Grupo Modelo in 2013. Before that deal could be approved, Modelo's U.S. assets -- including Carona -- were sold to a smaller rival.
As younger drinkers turn in ever greater numbers to independent breweries, the global market leaders have been trying to defend their market share.
AB InBev has swallowed Seattle's Elysian Brewing, Oregon's 10 Barrel Brewing and Chicago-based Goose Island in the last year or two.
SABMiller has also tapped into the craft beer scene, buying one of the UK's most successful independents, London's Meantime Brewing Company.
