Worldpay Group plc (WPYGY)  shares surged to an all-time high Tuesday after receiving multiple takeover approaches, sending the U.K.'s largest payments processor to the top of the FTSE 100.

Worldpay shares were marked 31% higher in London to change hands at 418.9 pence each at 2;45 pm local time, extending a 40% gain over the past three months and giving it a market value of £8.3 billion ($10.7 billion).

The group confirmed Tuesday, July 4, that it had received preliminary approaches from Vantiv Inc. (VNTV) and JP Morgan Chase Bank (JPM - Get Report) in relation to the potential acquisition of the entire issued, and to be issued, share capital of Worldpay.

Vantiv is a U.S.-based payments processor listed on the New York Stock Exchange.

"There can be no certainty either that an offer will be made nor as to the terms of any offer, if made," the company said in a brief statement.

Worldpay, the firm behind many stores cash register payments technology, was carved out of Royal Bank of Scotland RBS after the bank was bailed out following the financial crisis. Worldpay reported a profit before tax of £264 million in 2016, up from £19 million in 2015.
