 A deal for Paya, which is owned by private-equity firm GTCR, could be announced as early as next week, the sources said, cautioning that talks could still fall apart at the last minute and requesting anonymity because the negotiations are private. FinTech Acquisition III, GTCR and Paya declined to comment. Special-purpose acquisition companies SPACs are shell companies that raise money in an initial public offering IPO to pursue an acquisition at a later date, with the acquired company then going public as a result of the deal.
