Silver Lake has agreed to sell Mercury Payment Systems to Vantiv (NYSE: VNTV) for an aggregate price of $1.65 billion. A provider of payment products and services, Mercury embeds its tech within third-party software apps in order to combine payment and business management functionality. 2013 saw Mercury generate net revenue of $237 million, growing 17% year-over-year, and adjusted EBITDA of $93 million. In early April, it filed for a $100 million IPO; per the deal, the offering will be withdrawn. Silver Lake holds a 62.3% stake in the company, which the firm acquired in 2010 for a reported $450 million, giving Mercury an estimated $700 million valuation at the time.
