Paysafe said it had been approached by the consortium made up of funds managed by Blackstone and funds managed by CVC Capital Partners in early May and, after turning down a number of indicative proposals, had granted the bidders due diligence access on the basis of the 590 pence per share proposal.
Paysafe said the proposal represented an about 34 percent premium to its volume weighted average price for the six months to June 30, the day before broad sector consolidation speculation hit the market.
Representatives for Blackstone and CVC were not immediately available to comment.
Old Mutual Global Investors, Paysafe's largest shareholder with a stake of about 10.3 percent in the group, has signed a non-binding letter of support for the possible offer, the group said.
If the deal goes through, Paysafe's entire capital will be incorporated in a newly formed company, with the consortium taking full ownership.
While banks have been trying to develop and buy more sophisticated technology, companies like PayPal and Paysafe have gained a large market share as consumers have adopted online shopping and cashless transactions.
