Ares Management and Kayne Anderson Capital Advisors are no longer going ahead with a planned merger.
The two alternative investment managers had planned a merger that would have created a company with a combined $113bn (鈧102bn) in assets under management.
The move, first announced in July, is no longer going ahead, with both companies citing current market conditions in the energy sector.
Ares will, however, invest $150m in LA-based Kayne Anderson鈥檚 energy activities, including energy private equity, private energy income and energy infrastructure marketable securities funds.
The companies will look for additional collaborative marketing opportunities, including jointly managing separate accounts.
Tony Ressler, Ares chairman and chief executive, said: 鈥While we continue to strongly believe in Kayne and the long-term energy investment opportunity, it became clear this was not the right time to bring together our cultures and business models into a merged public company.鈥
Ric Kayne, Kayne鈥檚 founder and chairman, said that, after 鈥渕any discussions鈥, the company had decided it could create more value for investors by staying a private.
鈥淜ayne is uniquely well-positioned to take advantage of the markets we are in, and we are delighted that Ares and its principals have chosen to capitalise on this opportunity by investing with us directly,鈥 he said.
Ares Management teamed up with European retail specialist Redevco to invest 鈧500m in Spanish and Portuguese retail real estate.
