Fiserv, Inc. is a Milwaukee, Wisconsin-based global payments and financial technology provider.

According to the lawsuit, in July 2025, Fiserv updated its 2025 financial guidance following a “re-underwriting” review of its new initiatives and product lines. The Company told investors that, despite certain project delays, its initiatives remained fundamentally sound. The complaint alleges that these statements were materially false, as on October 29, 2025, Fiserv disclosed that the assumptions underlying its July 2025 guidance “would have been objectively difficult to achieve even with the right investment and strong execution.”

Following this disclosure, Fiserv's stock price declined by $55.57 per share, or 44%.
