On 6 August 2010, Advent International and Bain Capital agreed to acquire Worldpay for £2.025bn, including a £200m contingent consideration, and appointed Ron Kalifa, who had previously headed up the global transaction services division with RBS, as CEO.
[13][14][15][16] The combined entity was to keep the "Worldpay" name, and would be headquartered and listed in the United States, with internal operations continuing to be based in the U.K.[17] The transaction was completed on 16 January 2018.
[18] There was initial concern from UK politicians over whether the merger was as a result of the fall in the pound's value since 2016, turning British assets into bargains for foreign investors.
In March 2019, Fidelity National Information Services (FIS), a payment rival based in Florida, bought Worldpay Inc. in a deal worth £32 billion.
