Wall Street’s Longest-Serving C.E.O. Says He Isn’t Going Anywhere<br />A handful of earlier would-be successors left JPMorgan after it was clear<br />that Mr. Dimon wouldn’t be stepping aside in time for them to take over — sparking concerns among some industry observers that the bank wasn’t doing a good job of grooming talent to eventually replace him<br />Monday’s announcement identified Mary Erdoes, 50, who runs the bank’s asset<br />and wealth management arm; Doug Petno, 52, who runs the commercial banking division; and Marianne Lake, 48, the bank’s finance chief, as among the up-and-comers.<br />In an announcement that seemed designed in part to address questions about the bank’s succession planning, JPMorgan said two of his deputies, Daniel Pinto<br />and Gordon Smith, would be promoted to the joint roles of presidents and chief operating officers.<br />Both Mr. Pinto and Mr. Smith are old enough that it is unclear whether they will be serious<br />contenders to eventually replace Mr. Dimon, especially if he sticks around for five years.<br />Since taking JPMorgan’s helm more than 12 years ago, Mr. Dimon has survived a financial crisis, a monumental trading blowup and throat cancer.<br />James Dimon, the chairman and chief executive of JPMorgan Chase, already has outlasted all of his Wall Street peers.<br />Mr. Pinto, 55, has led JPMorgan’s investment bank for five years.
