Daniel Pinto, the long-serving number two to CEO Jamie Dimon, is set to step down in June, leading to a significant reshuffling within JPMorgan Chase. The bank has named Jenn Piepszak as the new Chief Operating Officer, taking over from Pinto, who has announced plans to retire in 2026. Despite being viewed as a potential successor to Dimon, Piepszak has stated that she does not aspire to the CEO position. The changes raise questions about the future leadership structure of the bank as it moves forward in a competitive financial landscape.
