Fiserv sees revenue dip as it tackles core banking attrition and expands merchant solutions with AI support.

Fiserv reported a 2.4% revenue decline to $4.68 billion in Q1 2026, driven by a 4% drop in organic revenue and challenges in its core banking segment due to higher attrition. CEO Mike Lyons highlighted the company's strategic focus on execution under the "ONE Fiserv" plan, including hiring experienced leaders and expanding its Clover platform into new sectors like healthcare. To address client attrition and improve service, Fiserv is leveraging AI, reducing client inquiry resolution time by 27% and high-impact incidents by 60%. The company views these efforts as key to stabilizing its financial solutions business amid shifting consumer spending patterns influenced by external factors like rising gas prices.
