The mega-merger between beer giants Anheuser-Busch InBev (BUD) and SABMiller (SBMRY) foreshadows more consolidation ahead in the beer industry, according to one expert.

"I would expect to see more consolidation from the other players," said Warwick Business School Professor John Colley, who is based in the U.K. "They usually have to merge to get the same economies of scale, scope and leverage with distribution."

The deal creates the largest beer company in the world.

"One in three beers bought globally will be made by this new mega-brewer," he added. "The top four players are going to have half of the global market. Research shows the less players there are in a particular market, the higher profit, and I think that's where AB InBev and SABMiller are going with this."

AB InBev will divest of its nearly 60% stake in MillerCoors as part of the transaction, in a move to please regulators worried about one company having too much market power.

"They're selling it to Molson Coors (TAP - Get Report) of Canada," Colley said. "There's no way the deal [would pass regulators] if this stake had not been sold."

Irrespective of the sale, AB InBev isn't out of the woods yet when it comes to anti-trust concerns.

"There may be some complications in South America and Mexico, where 80% of AB InBev's trade lies, and there's also a substantial amount of SABMiller trade there too," Colley said.

China could be problematic for the beer giant too. After the merger, the company will have a roughly 40% market share in the region. "I would imagine they will run into competition issues there.'"

Meanwhile, Colley thinks SABMiller shareholders will come out ahead once the deal closes. "The $107 billion is 40% above the pre-bid price, so I think SABMiller shareholders are getting a good deal," he added.

But Colley isn't as bullish for shareholders of AB InBev. "The $107 billion is a steep price and the cost savings are estimated to be 7% of sales, a figure well below expectations," he said. "Research shows most acquisitions result in destroying value rather than creating it."
