Worldpay, a company indirectly backed by Advent International and Bain Capital, has completed its public offering, listing on the LSE under the symbol WPG. The company priced its offering at 240 pence per ordinary share, raising total gross proceeds of approximately £2.2 billion and garnering a market cap of £4.8 billion. The company itself will receive about £948 million of the gross proceeds, with its Advent- and Bain-backed institutional shareholder receiving total proceeds of over £1.2 billion. Acquired by Advent and Bain for £1.7 billion in 2010, the U.K.-based payments processer typically processes 31 million mobile, online and in-store transactions per day. Its solutions are delivered by 4,500 personnel through its London headquarters and 25 offices located in 11 different countries. According to reports, Blackstone and Hellman & Friedman had joined efforts in an attempt to persuade the company's PE backers to ax IPO plans earlier this year, but clearly to no avail.
