Profit for the quarter ended November 30 rose to $119.6 million, or 55 cents a share, from $107.8 million, or 45 cents a share, a year earlier. Analysts polled by Thomson Financial had expected 55 cents per share on revenue of $1.04 billion. However, Constellation lowered its full-year profit outlook, in part due to costs from its recent acquisition of Fortune Brands Inc.

The company earned $31.1 million, or 72 cents per share, compared with $33.6 million, or 77 cents per share, in the same quarter a year ago. Analysts had expected profit of 82 cents per share on revenue of $500.6 million, according to analysts polled by Thomson Financial.

It's been said that if the U.S. state of Georgia were an independent nation, it would have the 18th largest economy in world. The "Empire State of the South" ranked tenth in U.S. in per capita personal income in 2005, and has one of the fastest growing populations in the U.S. -- about a million additional people between 2000 and 2005. Its diverse industrial output ranges from peaches and peanuts, to textiles, food processing, and aircraft manufacturing, to publishing and tourism. Georgia is home to such corporate giants as Coca-Cola Co. (NYSE: KO); Delta Air Lines Inc. (NYSE: DAL); Home Depot Inc. (NYSE: HD); UPS (NYSE: UPS); Newell Rubbermaid Inc. (NYSE: NWL), and Equifax Inc. (NYSE: EFX).

It's also home to Acuity Brands Inc. (NYSE: AYI) and Global Payments Inc. (NYSE: GPN), both of which represented Georgia on the Forbes 2007 list of 100 best mid cap stocks.
