What do you get when you add 4 and 11? In the case of Worldpay Inc., it’s 1. The merged version of the former Vantiv Inc. and Worldpay plc moved to the number-one position in The Strawhecker Group’s annual directory of U.S. merchant acquirers.
Released Monday, the directory ranks industry participants by their estimated total processing volume in 2017. Vantiv, number 4 last year, and Worldpay, number 11, merged in January, adopting the Worldpay name for the company. The merger moved the company to the top spot, with an estimated $1.12 trillion in U.S. processing volume. The new Worldpay serves an estimated 1.2 million merchants across the globe, according to the 2017 documents related to the merger.
