“The synergies are expected to come from economies of scale on raw materials and packaging, alignment of brewer, bottling and shipping productivity, best practice sharing related to cost management and closing down of overlapping regional headquarters and the SAB corporate headquarters,” Trevor Stirling, managing director and analyst at Sanford C. Bernstein wrote in a research note.

A-B InBev is buying SABMiller to add new brands in countries it is not currently present in, particularly in fast-growing markets in Africa.

“Clearly when you combine two companies that are so similar you’re going to have a lot of duplications in functions, such as back-office HR and marketing,” said Morningstar equity analyst Philip Gorham. “An important part of A-B InBev’s playbook is taking out costs.”

The deal has received backing from SABMiller’s board but awaits approval from the company’s shareholders. Some smaller shareholders have turned against the deal since a plunge in the value of the British pound eroded its value. Analysts, however, say it should be approved in a vote on Sept. 28.
