Grocery and food retail companies operate supermarkets, warehouse clubs, natural food retailers, drug stores, and pharmacy chains. Kroger is the largest pure-play US grocer, while Costco and Walmart lead in warehouse and supercenter formats. Food retail benefits from non-discretionary spending but competes on price, freshness, private label quality, and digital grocery fulfillment. Pharmacy operations at CVS and Walgreens face structural headwinds from PBM reform and clinic model pivots.
Identical-store sales (IDs) excluding fuel and pharmacy reveal core grocery health. Watch fuel center margins at Kroger and Costco — high margin, high traffic. Digital order penetration and pickup vs delivery mix signal fulfillment cost evolution. Pharmacy comparable script counts indicate clinic strategy traction.
