Suit seeks investors who bought Fiserv securities from July 23–Oct 29, 2025, alleging misleading statements about the company’s business, forecasts, and growth. On July 23, 2025 Fiserv set 2025 organic revenue guidance at 10% and raised the EPS low to $10.15, citing an anticipated back‑half ramp. On Oct 29, 2025 it reported a Q3 adjusted revenue decline, cut organic growth to 3.5–4% and EPS to $8.50–$8.60, and announced its CFO’s exit plus board changes replacing Simmons and audit chair Kevin Warren effective Jan 1, 2026. CEO Michael Lyons said a review found prior guidance relied on overly optimistic assumptions about volume, sales and productivity. Shares fell over $59 intraday, erasing $32 billion in market value.
