Neil Davids, David Janashvili and David Yeh are managing directors, the former two joining from BNP Paribas <BNPP.PA> and Canaccord Genuity CF.TO, also in New York, both with prior energy transition and renewables experience. Yeh, a climate investor and a senior advisor in President Barack Obama's administration, will be based in CIBC's new San Francisco office. The expansion comes even as investment banks and other firms in the U.S. slow hiring as concerns about inflation and a tight labour market.
