Morgan Stanley President Colm Kelleher, who helped navigate the firm through the financial crisis and was once seen as a potential successor to Chief Executive Officer James Gorman, plans to depart at the end of June.
Kelleher, 61, will continue as a senior adviser after his official retirement, according to an internal memo Gorman sent employees on Thursday.
"I am extremely grateful to have been able to call him my partner," Gorman said in the memo. "His sharp mind, wicked humor and Irish charm sets him apart in the world of all-too-often dull business leaders."
Kelleher, who joined the New York-based company in fixed-income sales in 1989, has overseen Morgan Stanley's investment bank and trading operation since 2010. By taking on the retail brokerage in 2016, he had responsibility for the firm's two biggest businesses.
Kelleher's departure marks a generational shift at the firm and opens up the competition to replace Gorman, who's said he plans to stick around several more years. Gorman didn't name a new president, and said in the memo that executives who previously reported to Kelleher will report to the CEO after the departure.
Morgan Stanley in July named Ted Pick, 50, to head the investment-banking and trading division, bolstering his position as a possible successor to Gorman. Franck Petitgas, 58, who's also considered a CEO candidate, was appointed head of the bank's international operations as part of the same management shuffle.
Andy Saperstein and Shelley O'Connor, co-heads of the retail brokerage, are also considered in the succession mix, along with asset-management head Dan Simkowitz, Chief Financial Officer Jon Pruzan and tech chief Rob Rooney.
