Fidelity National Information Services' legacy operations provide core processing and ancillary services to banks, but its business has expanded over time. By acquiring Sungard in 2015, the company now provides record-keeping and other services to investment firms. With the acquisition of Worldpay in 2019, FIS now provides payment processing services for merchants and holds leading positions in the United States and United Kingdom. About a fourth of revenue is generated outside North America.
