Mercury Payment System may be headed for an initial public offering, according to The Denver Post. The Durango, Colo.-based payments processor told the newspaper that it filed a confidential draft registration statement with the Securities and Exchange Commission.

The Post noted that Reuters, citing confidential sources, reported last month that Mercury's majority private-equity owner, Silver Lake Partners, had hired JPMorgan Chase, Barclays and Morgan Stanley to lead a potential public offering that would value the company at $2.5 billion. That sale could occur in the first half of 2014.
