Vantiv, a leading, integrated payment processor differentiated by a single, proprietary technology platform, filed on Thursday with the SEC to raise up to $100 million in an initial public offering. However, the placeholder $100 million deal size will likely be replaced with a higher number as the IPO moves forward. In July, the Wall Street Journal reported that Vantiv hopes to raise between $750 million and $1 billion at a valuation of $4.5 billion. The Symmes Township, OH-based company, which was founded in 2009 and is backed by private equity firm Advent International, booked $1.4 billion in sales for the 12 months ended June 30, 2011. J.P. Morgan, Morgan Stanley, and Credit Suisse are the lead underwriters on the deal. No pricing terms were disclosed.
