The head of Anheuser-Busch InBev has refused to be drawn on the outcome of global regulatory reviews that could change the shape of his company's recently-confirmed takeover of SABMiller.

In a media call this morning, Carlos Brito was asked about potential reviews in China and the US, where overlaps between SABMiller's and A-B InBev's operations could interest anti-trust authorities. Brito replied that it is too early to comment, later adding: “We are looking to bring all potential reviews to a timely and appropriate resolution.”

A-B InBev announced this morning that it will acquire rival brewer SABMiller in the biggest takeover the alcohol industry has seen. The company also confirmed that it has agreed to the sale of SABMiller’s interest in MillerCoors to Molson Coors for around $12bn.

However, asked if he had talked to US authorities about whether the sale off MillerCoors would diffuse regulatory issues, Brito said the company was committed to being “pro-active” in resolving potential disputes.

On China, where A-B InBev is a major player in the beer segment and SABMiller runs a JV for the leading Snow beer brand, Brito said: “It is not appropriate for me to pre-empt the outcome of the regulatory review and the view of the regulatory authorities.” Asked if he had spoken to authorities in China, he said it was “too early to comment on that”.

Brito also gave few details on job losses resulting from the takeover, but said headquarters and regional headquarters would likely be most affected. “When any company gets together there will be duplication at some level, mostly at headquarters level and regional level,” he said.

No name has been given to the newly enlarged A-B InBev yet, and Brito said it was an issue “not at the top of our list at this point”.
