In my previous post I suggested to buy both companies. But what shall we do now? After weeks of negotiation and months of speculation, beer giants SABMiller PLC and Anheuser-Busch InBev SA on Tuesday said they’ve agreed on the keys terms for a merger.The price looks to be about $105 billionThe share price The £44-a-share bid offered to the majority of SABMiller’s shareholders marks a 50% premium to the brewer’s trading level on Sept. 14, the day before media speculation about a potential merger erupted. SABMiller shares jumped 8.5% to £39.31 on Tuesday in London trade after the takeover agreement, still putting it more than 10% below the offer price. Shares of InBev rose 1.8% in Brussels, while U.S.-listed shares of the brewer climbed 1.9% in premarket action. Watch out for the world’s largest brewer with 29% market shareThird-largest merger ever — and biggest takeover of U.K. companyBy Oct. 28, put up or shut up The two brewers have agreed on key terms for the merger, but still need to work out details for a formal agreement. The deadline under U.K. takeover rules for that was Wednesday, but SABMiller has requested an extension to the so-called put-up-or-shut-up deadline to Oct. 28. So still buy both? Or wait?
