The UK company is owned jointly by Advent International and Bain Capital. The private equity firms bought Worldpay from the Royal Bank of Scotland in 2010 for $2.7 billion. Worldpay processes more than 31 million transactions every day across 146 countries for 400,000 retailers including Apple AAPL . In 2014, Worldpay saw $1.3 billion in revenue, brought in $725 million in revenue in the first six months of 2015, and ended in June up 13% from the previous year. Worldpay brought in profits of $583.6 million in 2014, and $284 million in the first six months of 2015. The company had recently received acquisition bids from rivals including French payments company Ingenico and Germany’s Wirecard. Investment funds Blackstone and Hellman & Friedman were also bidding to buy Worldpay. If Worldpay does go public, it will be interesting to see how the company preforms in investors eyes. There are a number of payments companies that are newly on the public markets, including PayPal PYPL , newly spun off of Ebay EBAY . Payments giant Ant Financial, which was spun out of Alibaba BABA is also expected to go public in the coming year.
