Aris Prepoudis, CEO of investment manager RobecoSAM, is departing from the firm following a management restructuring.
RobecoSAM, which focuses on sustainable investment, is a sister company of Dutch money manager Robeco. Both firms are owned by ORIX Corp.
The new management structure aims to "strengthen ties between RobecoSAM and Robeco in order to fully unlock the potential between the two companies," said a joint news release Friday.
"After successfully refocusing RobecoSAM's operations and distribution setup and achieving profitable growth in a short period of time," the board and Mr. Prepoudis "have decided to part ways," said the release. His plans could not be learned.
RobecoSAM will be led by co-CEOs Marius Dorfmeister, responsible for areas including client relations and client portfolio management, and Daniel Wild, who will be responsible for investments, sustainable investment research and environmental, social and governance ratings.
Mr. Dorfmeister is head of global clients and marketing; Mr. Wild is head of sustainability investing research and development. A spokeswoman for RobecoSAM said each will continue to oversee these responsibilities.
Rainer Baumann, head of investment management and a member of the executive committee at RobecoSAM, will step down from the board but remain in his role at the firm.
RobecoSAM and Robeco will also establish a multisite Rotterdam and Zurich-based team for trends and thematic investment, with €7 billion ($8.5 billion) in assets under management. The spokeswoman said it will be composed of 10 strategies, including RobecoSAM's smart energy, sustainable water and agribusiness equity strategies, and Robeco's global fintech equities and global growth trend equities strategies.
The firm hired Mark van der Kroft as head of the new team. He was director, strategic institutional business development at NN Investment Partners. NN Spokesmen could not be reached for details on any replacement.
RobecoSAM's board of directors will introduce a "matrix" organization, with functional oversight from Robeco. A Robeco spokeswoman said under this new organization there will be functional reporting lines established from senior managers of RobecoSAM to Robeco.
The changes will become effective once regulatory approval is obtained.
Robeco has €293 billion in assets under management. RobecoSAM has assets under management, advice and/or license of about $20 billion.
