March 17 (Reuters) - Payments processor Shift4 Payments' ( FOUR )

Chief Executive Officer Jared Isaacman said bids from

potential contenders have failed to "sufficiently value" the

company, Bloomberg News reported on Sunday.

The board determined that none of the "multiple offers"

received by Shift4 adequately valued the business or the

company's future, even though the offers were above its Shift4's

current share price, the report said, citing a memo to the

company's staff on Friday.

Shift4 did not immediately respond to a request for comment

on the Bloomberg report.

Reuters had reported in February that Fiserv ( FI ) and

Amadeus Group are competing to acquire Shift4 Payments ( FOUR ),

which has a market value of nearly $7 billion.

Shift4 collects fees from clients, ranging from restaurants,

casinos and hotels, to sports teams like the San Francisco

49ers, to facilitate their payments. It processes more than $200

billion worth of annual transactions for over 200,000 customers,

according to its website.
