UBS Group AG is promoting a long-time executive in the U.S. as it seeks to expand in the region and offer ultra-rich clients more bespoke investments. Jason Chandler will become head of wealth management in the U.S. after more than two decades at the bank, according to a memo sent to staff Monday. That gives him oversight of almost 7,000 financial advisers in the region. He’s been co-leading investment platforms globally, and succeeds Brian Hull, who’s becoming executive vice chairman Americas. The changes will be effective Jan. 1.
