Fiserv

Fiserv’s shares plummeted 44% after slashing its earnings outlook and announcing a leadership shakeup. The company lowered its full-year adjusted EPS forecast to $8.50-$8.60 and revenue growth to 3.5%-4%, citing deteriorating economic conditions in Argentina as a factor. Q3 adjusted EPS and revenue also missed estimates. Takis Georgakopoulos and Dhivya Suryadevara will share the co-president role, and Paul Todd is the new finance chief. Three new members will join the board in 2026. Fiserv is transferring its stock listing to the Nasdaq.
