iM Global Partner is to sell its stake in investment manager Richard Bernstein Advisors to Janus Henderson Group, following the latter’s announcement it will acquire 100% of the business.
RBA focuses on longer-term investment strategies combining top-down, macroeconomic analysis and quantitatively-driven portfolio construction. It has some $20bn under management. Janus Henderson stated that the acquisition would “substantially enhance its position in model portfolios and SMAs. At the completion of the transaction, Janus Henderson will rank among the top 10 model portfolio providers in North America”. The deal is expected to close in Q2 2026.
The announcement comes less than a month after Janus Henderson itself came in scope of an acquisition deal, which will see Janus Henderson Group plc acquired by Trian and General Catalyst in an all-cash transaction at an equity value of approximately $7.4bn. The investor group includes strategic investors Qatar Investment Authority and Sun Hung Kai & Co. Limited. The deal is expected to complete by mid-2026.
RBA became a partner of iM Global Partner in July 2021. iMGP’s platform serves to support managers with distribution and marketing support to reach professional investors.
Philippe Couvrecelle, founder and CEO of iMGP, commented: “Our mission has always been clear: to identify leading boutique asset managers, partner with them to grow, and deliver high quality investment solutions to clients worldwide. Janus Henderson’s acquisition of RBA is a strong outcome for the firm and clients, and clear proof of our strength in identifying leading investment boutiques, and the value our partnership platform can create for our asset management partners.”
“iM Global Partner is a growth company. We already have ambitious plans to accelerate our expansion for the long term, and this transaction provides additional momentum to capitalise on our expertise in partner selection, forge new relationships, and further advance our growth strategy across Europe, the U.S., and Asia.”
Richard Bernstein, CEO and CIO at RBA, added: “iM Global Partner, as their name implies, has been an excellent and supportive partner of RBA over the past five years. All of us at RBA are extremely thankful for iMGP’s helping hand to aid our growth, and we wish them only the best of success for their future endeavours.”
