Global asset manager Janus Henderson has been acquired by Trian Fund Management and General Catalyst in a US$7.4 billion deal.
Trian has been a shareholder since 2020 and previously owned 20.6 per cent while General Catalyst is a technology venture capital firm and the proposal was first announced in October 2025.
The deal received unanimous approval and is expected to be completed in mid-2026.
Janus will continue to be led as private company by chief executive Ali Dibadj and will maintain its presence in London and Colorado.
Janus Henderson was formerly listed on the ASX until November 2023 when it de-listed in favour of only being on the New York Stock Exchange (NYSE).
The firm was formed from the merger of Janus Capital and Henderson Global Investors in 2017 but the original Henderson Group has Australian roots as it was formerly owned by AMP.
Dibadj said: “We are pleased with Trian’s and General Catalyst’s interest in partnering with us, which is a strong affirmation of our long-term strategy. During our 91-year history, Janus Henderson has been public and private at different times, and it has never lost focus on investing in a brighter future together for its clients and employees.
“With this partnership with Trian and General Catalyst, we are confident that we will be able to further invest in our product offering, client services, technology, and talent to accelerate our growth and deliver differentiated insights, disciplined investment strategies, and world-class service to our clients.”
Nelson Peltz, chief executive of Trian, said: “As a significant shareholder of JHG with Board representation since 2022, we are proud of the company’s performance in recent years led by Ali and his outstanding team. We see a growing opportunity to accelerate investment in people, technology, and clients.
“The partnership with General Catalyst allows us to bring our shared entrepreneurial spirit and complementary strengths across operational excellence and technological transformation to Janus Henderson.”
