SABMiller shareholders have been urged to accept AB InBev’s revised takeover bid by two influential advisory groups.

Glass Lewis and International Shareholder Services (ISS) both advised SAB investors to vote in favour of the £79bn deal on September 28.

AB InBev revised its offer in July – to £45 a share – following the fall in the value of sterling but some shareholders were still unhappy. Last month it was agreed that SABMiller’s two biggest backers, Altria and BevCo – who have already pledged to back the deal – should be treated as a separate class of shareholder.

It comes as China Resources Beer Holdings Co was revealed to be considering a bid for SAB’s central and eastern European assets for a rumoured $6bn.
