Fiserv appoints Takis Georgakopoulos as CEO amid leadership shakeup

Fiserv named co-president Takis Georgakopoulos as chief executive after Mike Lyons resigned to return to banking, capping a turbulent 13 months and a broad leadership reorganization. Lyons had launched a transition year with weaker results and investor scrutiny, while Georgakopoulos—long known in payments and banking—signals a push to modernize the Clover platform and stabilize the company amid activist pressure from Jana Partners. Lyons will become CEO of Truist Financial on Sept. 1, and Fiserv faces continued scrutiny as its stock has fallen sharply while it charts a new course.
