Shares of financial technology firm Fiserv Inc surged more than 5% in pre-market trading on Tuesday following reports that the company is in talks with major banks like JPMorgan Chase & Co and Bank of America Corp regarding the sale of its debit card payment infrastructure business.

In recent months, JPMorgan Chase, Bank of America, Wells Fargo & Co, and PNC Financial Services Group Inc have held preliminary discussions about acquiring Fiserv's STAR payment network. This network provides transaction routing services for over 115 million debit cards issued by more than 2,800 financial institutions, covering ATM transactions, e-commerce, and merchant purchases.

The interest in this acquisition is driven by banks' desire to circumvent federal caps on debit card interchange fees. Current regulations stipulate that large banks with assets exceeding $100 billion must adhere to fee caps when processing debit card transactions through third-party networks. However, if a bank owns its own payment network, it is exempt from these restrictions. Following Capital One Financial Corp's acquisition of Discover Financial Services for $50.6 billion to gain its own network, other industry players are seeking to follow suit.

Nevertheless, the potential deal faces significant hurdles. Several banks have assessed the situation and concluded that the likelihood of proceeding is low, citing concerns that such a move could provoke strong opposition from lawmakers, regulators, and merchant groups. Fiserv's stock price has fallen approximately 70% from its peak last year as the company navigates a challenging transition period. No framework agreement has been reached between the involved parties.
