The international brewer is expected to report a year-over-year decline in earnings and revenue for the latest quarter.
Analysts have estimated earnings of $1.26 per share on $11.65 billion in revenue.
Last year, AB InBev reported earnings of $1.42 per share on $12.24 billion in revenue for the 2014 third quarter.
Earlier this month, Belgium-based AB InBev offered to acquire SABMiller (SBMRY) for about $103.95 billion, but the brewer will not decide on a formal bid until November 4, the Wall Street Journal reported.
The deadline was extended by a week for AB InBev to secure financing and to find a buyer for SABMiller's 58% stake in MillerCoors, sources told the Journal.
AB InBev stock is down 0.83% to $117.75 in afternoon trading on Thursday.
