Overview
- Shares plunged about 43% in one session, erasing roughly $29 billion in market value, and fell further the next day in the company’s worst trading day on record.
- Fiserv reduced its 2025 organic revenue target from about 10% to a range of 3.5%–4%, reflecting a reassessment of growth drivers.
- Executives said the lifting of exchange controls in April, peso depreciation, and easing inflation in Argentina stripped out unusually high local margins.
- Argentina had contributed roughly 10 percentage points to 2024 organic growth with operating margins about double the company average; 2025 year‑to‑date local growth of 56% now adds about two points.
- CEO Mike Lyons launched a “One Fiserv” restructuring and acknowledged other international businesses did not expand fast enough to offset Argentina, as Q3 revenue rose 1% to $5.26 billion with mixed segment results.
