JPMorgan Chase has made some changes to its leadership. Two investment bankers, Doug Petno and Troy Rohrbaugh, have been promoted to copresidents of the bank. This move sets them up as potential successors to the current CEO, Jamie Dimon.

The bank's current CEO has been leading the nation's largest bank for a long time, and it is expected that he will step down at some point. Further details about the promotion and what it means for the bank's future are available from the source, including information about another announcement made by the bank on Thursday regarding Marianne Lak.
