"We are not satisfied with our top line performance in 2013, which continues to be impacted by macroeconomic headwinds in a number of our markets," said CFO Felipe Dutra.
However, he said the integration of Modelo was going faster than forecast, and the company is already saving $250 million on an annual basis by combining operations.
Shares rose 2.1 percent at the start of trade in Brussels, to 76.13 euros.
AB InBev's global brands include Budweiser, Germany's Beck's, Belgium's Stella Artois, and Brazil's Brahma.
Dutra said the company sees big benefits in the near future as Brazil will benefit from the football World Cup in 2014 and the company's biggest brands have room to grow by selling into markets where they are not well-known.
Budweiser was introduced in parts of Central and Eastern Europe in the past 2 years but is already getting around 2 percent of market share "and in a premium position," Dutra said.
"So it's doing extremely well. Corona can follow that same path, why not?"
He described Corona as a brand that can "go where no others can go," due to its popularity at venues that are better-known for selling cocktails, such as dance clubs.
