Constellation Brands, Inc.
↗STZ
Constellation Brands is the largest provider of alcoholic beverages across the beer, wine, and spirits categories in the US, generating 84% of revenue from Mexican beer imports under top-selling brands such as Modelo and Corona. The rest of the business includes some remaining wine and spirits brands, categories where the company has pruned assets in recent years. With its exclusive rights tied to the Mexican beer brands effective only in the US, the firm has limited revenue exposure to international markets. Constellation owns a 10% stake in Canopy Growth, a medicinal and recreational cannabis producer in Canada, and has a 50/50 joint venture with glass manufacturer Owens-Illinois in Mexico.
