AmBev has again extended the period of its offer to buy the remaining shares in Argentina-based brewer Quinsa.

Belgium-based brewing giant InBev, which owns AmBev, announced the extension of the offer yesterday (5 March). The further postponement - to 16 March - follows Ambev's announcement late last month that it was extending the initial deadline to 27 February.

The offer has been made through Beverage Associates Holding, a Bahamian corporation and wholly-owned subsidiary of AmBev.

AmBev already owns around 97% of the voting interests and around 91% of the economic interests in Quinsa.

Earlier this month, a minority investor in Quinsa complained to the company over AmBev's plans to acquire the shares. Private equity firm Duma Capital Partners said that it was not satisfied with the handling of AmBev's offer to outstanding shareholders.
