Fiserv Faces Securities Class Action After Q3 Earnings Shock and Outlook Cut

Overview

• A class action has been filed in the U.S. District Court for the Eastern District of Wisconsin on behalf of Fiserv investors covering the July 23–Oct. 29, 2025 period.
• Complaints assert that Fiserv misled investors about the status of new initiatives after a July guidance “re-underwriting” and related revisions.
• On Oct. 29, 2025, Fiserv posted disappointing third‑quarter results and cut its financial outlook, citing prior guidance assumptions that would have been “objectively difficult to achieve.”
• Law‑firm notices report that Fiserv’s stock fell roughly 44% on Oct. 29 following the earnings disclosure and guidance reduction.
• Bernstein Liebhard, Gainey McKenna & Egleston, Robbins LLP, the Schall Law Firm, and Berger Montague are publicizing the case and seeking investors to join or request lead‑plaintiff status.
