FIS announced the close of its $35 billion acquisition of Worldpay Inc., a move that creates one of the world's largest e-commerce and payments companies. 

The combined firm will have pro forma revenue of $12 billion per year and become a leading provider of payments technology for the banking, merchant and capital markets communities. The close comes on the heels of the Fiserv acquisition of First Data Corp. 

"This is an exciting day for FIS and Worldpay and for the industry as a whole," Gary Norcross, chairman, president and CEO of FIS, said in a company release. "This transformative combination significantly enhances the scale, portfolio and global footprint of FIS to help our clients capitalize on growth opportunities at a time of rapid marketplace change."

Top executives at Worldpay will assume key roles in the newly combined company. Mark Heimbouch, president and chief operating officer at Worldpay, was named president of the FIS merchant services division. 

Stephanie Ferris, chief financial officer at Worldpay, was named enterprise-wide chief operating officer at FIS. Charles Drucker, former CEO and executive chairman at Worldpay, was named vice chairman of FIS. 

Earnings for FIS and Worldpay will be announced Tuesday, Aug. 6 at 8:30 EDT.
