Mizuho Securities analysts maintained their buy rating and a $156.00 price target for Fiserv (NASDAQ:FISV) amidst ongoing speculation about the possible acquisition of Shift4 Payments (NYSE:FOUR).

Fiserv, a leading financial technology services provider, along with Amadeus, has been rumored as a prospective buyer for Shift4 Payments, which specializes in integrated payment processing and technology solutions. However, Amadeus has publicly declared its lack of interest in the acquisition.

Shift4 Payments announced on November 8 that it was exploring strategic options, sparking discussions about potential acquisition interest from various parties. Despite Amadeus IT Group publicly stepping back from acquiring Shift4 Payments, Fiserv has remained silent regarding its acquisition intentions.

Mizuho believes acquiring Shift4 Payments could significantly enhance Fiserv's organic growth within North America, bolster its footprint in the restaurant and hospitality industries, and address concerns about inflation in Argentina.
