Distell Group boosted revenue in South Africa and across the continent as a deal between the country’s biggest wine exporter and Heineken NV continues to go through a regulatory approval process. While Heineken’s offer of about €2.3-billion for Distell has got support from local shareholders, the final steps to buy the wine, brandy, liqueur and whisky maker are still dependent on the Competition Tribunal of South Africa’s ruling. The outstanding approvals are “considered substantive in nature,” the company said on Thursday.
