DGX vs STZ Comparison

Quest Diagnostics is a leading independent provider of diagnostic testing, information, and services in the US. The company generates over 97% of its revenue through clinical testing, anatomic pathology, esoteric testing, and substance abuse testing with specimens collected at its national network of roughly 2,400 patient service centers, as well as multiple doctors offices and hospitals. The firm also runs a much smaller diagnostic solutions segment that provides clinical trials testing, risk-assessment services, and information technology solutions.

Constellation Brands is the largest provider of alcoholic beverages across the beer, wine, and spirits categories in the US, generating more than 90% 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.
