WST vs YUMC Comparison

West Pharmaceutical Services is based in Pennsylvania and is a key supplier to firms in the pharmaceutical, biotechnology, and generic drug industries. West sells elastomer-based packaging components (including stoppers, seals, and plungers), nonglass containment solutions, and auto-injectors for injectable drugs, which include large-molecule biologics, peptides such as GLP-1 receptor agonists, and small-molecule drugs. The company reports in two segments: proprietary products (about 80% of total revenue) and contract-manufactured products (about 20% of total revenue). It generates approximately 55% of its revenue from international markets and 45% from the United States.

Yum China is the largest restaurant operator in China, with over 18,000 locations and USD 12 billion in systemwide sales as of 2025. It generates revenue mainly from its own restaurants and franchise fees. While KFC and Pizza Hut are its flagship brands, Yum China's portfolio also includes Little Sheep, Taco Bell, Huang Ji Huang, and Lavazza. As a trademark licensee of Yum Brands, Yum China pays 3% of KFC and Pizza Hut's systemwide sales to its former parent, from which it spun off in 2016. However, even before the separation, Yum China was granted substantial autonomy, giving its Chinese leadership decision-making authority over menu, supply chain, and marketing-an unusual practice for Western chains at the time.
