Constellation Brands shares pulled back in after-hours trading following the company's second-quarter fiscal 2027 earnings release on October 6. While the company reported a 5% increase in beer sales and a 17% rise in wine and spirits revenue, the market reaction suggests investors remain cautious regarding the company's broader outlook and tightening margins. This downward move follows a regular session where the stock had posted modest gains despite ongoing analyst concerns about the impact of changing consumer habits and GLP-1 usage on alcohol consumption.
