Anheuser-Busch InBev is to raise up to US$30bn in the second-biggest corporate bond deal, to help fund its takeover of SABMiller, according to reports.

The deal, which is expected to be announced today, would lag only Verizon's 2013 bond sale, which raised almost $50m, the Financial Times reported. Analysts said AB InBev needs to raise a total of $60bn from global credit markets and could launch another bond deal in the US or Europe.

AB InBev agreed a US$107bn takeover of SABMiller late last year and is waiting on regulatory approval in its global markets. The deal, which will see the company increase its presence in Africa, was initially expected to complete during the second half of this year, although just-drinks learned in November that it could take up to May 2017 or beyond to close.
