A dispute between Mexican brewer Grupo Modelo and Anheuser-Busch InBev is set to go before an arbitration panel in the US this month.

Modelo is seeking up to US$2.5bn in damages from the brewing giant, said Anheuser-Busch InBev in its half-year results announcement last week. An arbitration hearing is set to begin in New York this month, A-B InBev said.

Modelo filed for arbitration in October last year, at the time of InBev's $52bn takeover of A-B.

The Mexican brewer argues that an agreement between itself and A-B prohibits the automatic transfer of A-B's 50% non-controlling stake in the company to "a competitor in the beer business".
Modelo also argues that the agreement prohibits A-B from disposing of its stake "without first giving the controlling shareholders of Grupo Modelo an opportunity to purchase the shares".

A-B InBev CEO Carlos Brito said in the group's results conference call that Modelo's claim is "completely without merit".

He declined to comment further on the case.
