AmBev has extended once again 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 5 April - follows Ambev's announcement earlier this month that it was extending the deadline to today (16 March).

The offer, to buy up to 6.8m class A shares and 8.6m class B shares, has been made through Beverage Associates Holding, a Bahamian corporation and wholly-owned subsidiary of AmBev. BAH is offering US$3.35 per class A share and $33.53 per class B share.

When contacted by just-drinks, a spokesperson for InBev said: "The reason for AmBev extending the offer period for the second time is related to the regulatory process being unpredictable, particularly because we have regulators in two jurisdictions, the US and Luxembourg. Consequently, what is very typically done is to commence the offer for the minimum period legally permitted and extend as necessary."

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. When asked if there was a link between this and the deadline extension, the spokesperson said: "The extension is linked to the regulatory process, not to recent opinions expressed by some minority shareholders."
