The company was founded by James E. Stowers Jr. in 1958 as "Twentieth Century Mutual Funds", a family of no-load funds, in Kansas City, Missouri.[1] Stowers started the funds in 1958 with just $100,000 in assets from 24 shareholders.[2] He built his business concentrating on small investors. The company changed its name to American Century Investments in 1997.[3] American Century's headquarters are located at 4500 Main in Kansas City, Missouri, near the Country Club Plaza, and employs around 1,300 people.[citation needed]
In 2011, JP Morgan Chase sold their 41% stake in ACI to Toronto based bank CIBC.[4][5] CIBC resold its stake to Nomura Holdings in 2015 for around $1 billion as it could not gain full control of ACI.[6] The stake gave Nomura 10.1% of the voting rights.[7] The Stowers Institute for Medical Research holds the controlling majority stake in the company.[8] Between 2000 and 2019, the institute received over $1.1 billion in dividends from American Century.[9]
The company paid a $1.5 million settlement to its current and former employees after the United States Department of Justice found that it broke anti-trust laws by conspiring with another company to not compete for employees.[10] In August 2021, the company announced a vaccine mandate, requiring its employees to get the COVID-19 vaccine.[11]
