Janus Henderson Group is no longer a publicly traded company. It is now privately held by an investor group led by Trian Fund Management, General Catalyst and the Qatar Investment Authority after their take private deal closed on June 30, 2026.
Janus Henderson is a global asset manager that builds and runs mutual funds, exchange traded funds and separately managed accounts for individual investors, financial advisors and large institutions, with roughly three hundred seventy billion dollars in assets under management near the end of 2025.
The firm itself was formed in 2017 through the merger of Janus Capital Group, founded in Denver in 1969 by Thomas Bailey, and Henderson Group, founded in London in 1934, and it traded on the New York Stock Exchange under the ticker JHG until the 2026 buyout.
So why would an activist investor and a sovereign wealth fund pay about seven point four billion dollars to take a widely held public asset manager private?
This article looks at Janus Henderson ownership before and after the take private deal, its founding history, its CEO, its assets under management, the retirement products it offers, and how to reach the firm.
So let us get started.

What Janus Henderson Does
Janus Henderson is a global asset manager that builds and runs mutual funds, exchange traded funds and separately managed accounts for individual investors, financial advisors and large institutions.
The firm manages equity, fixed income and multi asset strategies, and many of its funds sit inside employer sponsored 401k plans and IRAs offered through outside brokerages and retirement platforms.
Unlike a bank or insurer, Janus Henderson does not hold customer deposits or issue policies. It earns fees for managing money on behalf of clients.
Ownership and Parent Company
For most of its public history, Janus Henderson had no single controlling parent company. It was a widely held public company owned by index funds, pension funds and other institutional investors.
That changed in December 2025, when Janus Henderson agreed to be acquired by an investor group made up of Trian Fund Management, General Catalyst and the Qatar Investment Authority in an all cash deal.
Shareholders approved the transaction in April 2026, and after regulatory approvals and client consents were secured, the take private deal officially closed on June 30, 2026, according to a Janus Henderson press release.
Janus Henderson is now a privately owned asset manager and no longer files quarterly results as a publicly traded company.

Public History and Shareholders Before Going Private
Janus Henderson shares traded on the New York Stock Exchange and the Australian Securities Exchange under the symbol JHG from 2017 until the 2026 take private deal closed.
As a widely held public company, its largest shareholders were mainly index fund managers such as Vanguard and BlackRock, which held stakes through their broad market and sector funds rather than as strategic owners.
Trian Fund Management, led by activist investor Nelson Peltz, had built a meaningful position in Janus Henderson stock before proposing the buyout, giving it leverage to help lead the take private transaction.
CEO and Founding History
Ali Dibadj has served as chief executive officer of Janus Henderson since July 2022, after previously working as an equity research analyst and later as CEO of AllianceBernstein.
Janus Henderson itself was formed in 2017 through the merger of two older asset managers: Janus Capital Group, founded in Denver in 1969 by Thomas Bailey, and Henderson Group, founded in London in 1934.
The 2017 merger combined Janus strong reputation in United States mutual funds with Henderson deep roots in European and global institutional investing, creating one of the larger independent asset managers in the world at the time.
Acquisition and Corporate History Timeline
Financials: Revenue and Assets Under Management
Janus Henderson reported total assets under management of roughly 370 billion dollars around the close of 2025, based on its fourth quarter and full year results release.
Assets under management measures client money the firm invests on behalf of others, which is a very different figure from the company own revenue or the 7.4 billion dollar price paid to take it private.
As a now private company, Janus Henderson is expected to stop publishing detailed quarterly revenue and earnings figures going forward, similar to other firms that exit public markets.
Even after the ownership change, Janus Henderson has continued making acquisitions of its own, including a January 2026 purchase of Richard Bernstein Advisors reported by Bloomberg.
Retirement and Investment Products
Janus Henderson offers mutual funds and exchange traded funds that commonly appear as investment options inside workplace 401k plans, IRAs and 529 education savings accounts.
The firm also manages actively run bond and equity strategies used by financial advisors building diversified portfolios for retirement and long term goals.
Janus Henderson does not typically open retirement accounts directly for individual investors. Most people access its funds through a brokerage, employer retirement plan or a financial advisor.

Anyone deciding whether to hold Janus Henderson funds inside a retirement account should speak with a qualified financial advisor about their personal goals, since this article is general information and not personalized advice.

Customer Service and Contact Information
Individual investors with questions about a Janus Henderson fund should generally contact the brokerage or retirement plan provider that holds the account, since Janus Henderson primarily manages funds rather than individual client accounts directly.
Financial advisors and institutional clients can reach Janus Henderson through the official contact page listed on its corporate website for region specific phone numbers and offices.
Janus Henderson Headquarters
Janus Henderson has long operated with dual headquarters in London, United Kingdom, and Denver, Colorado, reflecting its 2017 merger of a British firm and an American firm.
The company is legally incorporated in Jersey, a common structure for firms with major operations spanning both the United States and Europe.
Is Janus Henderson a Good Asset Manager
Because Janus Henderson mainly serves institutions and advisors rather than retail bank style customers, most public reputation tracking focuses on fund performance rather than customer service complaints.
According to Wikipedia, the firm ranks among the larger independent global asset managers by assets under management following its 2017 merger.
The 2026 take private deal itself is a signal that experienced investors like Trian and a sovereign wealth fund saw enough long term value in the business to pay a premium to buy it outright.
