Stowers Jr. as Twentieth Century Mutual Funds and headquartered in Kansas City, Missouri, is a privately held investment management firm renowned for its focus on delivering investment results to clients while supporting medical research.

The firm’s unique ownership structure sees over 40% of its profits funneled to the Stowers Institute for Medical Research, which it majority-owns, funding groundbreaking biomedical research, while Nomura Holdings holds a significant minority stake. With a global presence in cities like New York, London, and Hong Kong, and a workforce of around 1,400, American Century blends financial expertise with a mission to improve lives through both wealth creation and scientific advancement.
