GLONGHUI Feb. 29 | US financial data service company Fiserv and Spanish financial technology company Amadeus IT Group are bidding for US payment service provider Shift4 Payments. Sources said that Fiserv and Amadeus are the two main contenders in Shift4's ongoing sale process. The two companies are preparing to submit a final offer in the next few weeks, but it is uncertain whether the deal can be reached. Payment processors such as Shift4 boomed during the COVID-19 pandemic as customers switched to digital payment methods, but since then, in the face of increased competition and high inflation, some processors have been struggling to maintain growth. Earlier this week, Shift4 announced its fourth-quarter earnings report, and the outlook for 2024 is strong, with profit and revenue forecasts higher than market expectations.
