DRI vs DGX Comparison

Darden Restaurants is the largest restaurant operator in the US full-service space, with consolidated revenue of $12.1 billion in fiscal 2025. The company maintains a portfolio of 11 restaurant brands: Olive Garden, LongHorn Steakhouse, Cheddar's Scratch Kitchen, Ruth's Chris Steak House, Yard House, The Capital Grille, Seasons 52, Eddie V's, Bahama Breeze, The Capital Burger, and Chuy's. Darden generates revenue almost exclusively from company-owned restaurants, though a small network of franchised restaurants and consumer-packaged goods sales through the traditional grocery channel contribute modestly. At the end of fiscal 2025, the company operated 2,159 restaurants in the US.

Quest Diagnostics is a leading independent provider of diagnostic testing, information, and services in the US. The company generates over 95% of its revenue through clinical testing, anatomic pathology, esoteric testing, and substance abuse testing with specimens collected at its national network of roughly 2,300 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.
