It runs the core-banking, payments, capital-markets and card-issuer systems that thousands of banks and credit unions rent instead of building — a sticky, recurring-fee business. After buying then unwinding Worldpay, it re-focused in Jan 2026: it fully exited Worldpay and bought Global Payments' Issuer Solutions business (~$13.5B), adding card-issuer processing as a third pillar.
