MCD vs TMO Comparison

McDonald's is the world's largest restaurant brand, with nearly $131 billion in systemwide sales across more than 44,000 restaurants and over 100 markets. The quick-service chain built its early reputation on speed, consistency, and affordable hamburgers, and today its global menu spans burgers, chicken, breakfast, and beverages that have helped popularize American fast-food cuisine worldwide. The firm derives the bulk of its revenue from franchise royalties and rent (about 61%), with the remainder stemming from company-operated restaurants across three segments: the United States (41% of systemwide sales), international operated markets (34%), and international developmental/licensed markets (25%).

Thermo Fisher Scientific sells scientific instruments and laboratory equipment, diagnostics consumables, and life science reagents. The firm operates through four segments as of year-end 2024 (revenue figures include some cross-segment revenue): analytical technologies (17% of sales); specialty diagnostic products (11%); life science solutions (23%); and lab products and services, which includes CRO services (the remainder).
