Vista Equity Partners has agreed to exit its investment in TransFirst, selling the company to TSYS (NYSE: TSS) for about $2.35 billion in cash. The company is a provider of secure transaction processing services and payment enabling technologies, working primarily with small and medium-sized business in the U.S. The deal is expected to close 2Q. Vista had acquired the company for $1.5 billion in 2014, two months after TransFirst had submitted paperwork for an IPO to the SEC. Last October, the company again filed for an IPO, this time with Vista’s backing.
