(Reuters) - British payments processing firm Worldpay Group Ltd
The company, owned by investment groups Advent International and Bain Capital, said it expected a free float of at least 25 percent when it joins the London Stock Exchange next month.
A question mark had been hanging over the listing after the company attracted interest from a number of potential buyers in recent weeks.
These including French payments company Ingenico, which offered as much as 6.6 billion pounds including debt, a person familiar with the matter previously said.
Worldpay's private equity backers could have opted for a sale had the U.S. Federal Reserve decided to significantly increase interest rates on Thursday, sources said.
Shares in Ingenico jumped eight percent after it emerged that it would not be buying Worldpay.
Worldpay, which provides platforms that allow merchants to accept payments by cards and other methods, said the IPO would give it access to more capital raising options and help it reduce debt.
As well as Ingenico, rivals offering similar services include First Data, owned by private equity firm KKR.
The listing also paves the way for Worldpay's existing shareholders, senior management and employees to cut their investment in the firm.
The company's private equity owners bought it from Royal Bank of Scotland (L:RBS) in 2010 for about 2 billion pounds.
It plans to pay 20-30 percent of its profits after tax in dividends to shareholders, starting with an interim dividend for 2016.
Bank of America Merrill Lynch (N:BAC), Goldman Sachs (N:GS) and Morgan Stanley (N:MS) are leading the offer, with Barclays (L:BARC), Credit Suisse (VX:CSGN) and UBS (VX:UBSG) acting as joint bookrunners, the firm said.
