JANUS HENDERSON GROUP PLC
Janus Henderson Group Ltd — registered with Jersey’s Companies Registry under number 101484 and, since 12 December 2012, with UK Companies House as an overseas company under number FC031677 — is the ultimate holding company of the Janus Henderson group, a global active asset management business. The company traded as Janus Henderson Group plc from 6 December 2018 until 7 August 2026, when it was renamed Janus Henderson Group Ltd following the completion of a take-private acquisition. Before that it was known as Henderson Group plc (2013–2018). It is incorporated in Jersey, Channel Islands, as a public company limited by shares under the Companies (Jersey) Law 1991, with its registered office at 13 Castle Street, St Helier, Jersey JE1 1ES, and its principal business address at 201 Bishopsgate, London EC2M 3AE. Companies House records the company’s status as active.
Janus Henderson Group was formed on 30 May 2017 through the merger of US-based Janus Capital Group Inc. and UK/Australian-listed Henderson Group plc. The group provides active investment management services spanning equities, fixed income, quantitative equities, multi-asset and alternative strategies to individual and institutional investors, operating through subsidiaries including Janus Henderson Investors UK Limited, Janus Henderson Investors US LLC and other regulated asset managers across multiple jurisdictions.
For the year ended 31 December 2024, Janus Henderson Group reported consolidated revenue of $2,473.2 million (up 18% on 2023) and assets under management of approximately $379 billion, according to its Form 10-K filed with the US Securities and Exchange Commission. The group had more than 2,000 employees and offices in 25 cities worldwide as of that date.
Janus Henderson’s ordinary shares traded on the New York Stock Exchange under ticker symbol JHG. On 22 December 2025 the company announced a definitive agreement to be acquired by an investor group led by Trian Fund Management and General Catalyst, together with the Qatar Investment Authority, Sun Hung Kai & Co. Limited, Lunate Capital Limited and MassMutual, in an all-cash transaction subsequently amended to $52.00 per share. The take-private transaction completed on 30 June 2026, at which point Janus Henderson’s shares were delisted from the New York Stock Exchange and the company began operating as a privately held enterprise, with Ali Dibadj continuing as Chief Executive Officer.

Shareholders of Janus Henderson Group Ltd
Until 30 June 2026, Janus Henderson Group Ltd (then Janus Henderson Group plc) was a New York Stock Exchange–listed company (ticker: JHG), and its shareholder base was disclosed through SEC beneficial-ownership filings (Schedule 13G/13D) rather than a private company registry. Institutional and index-fund holders such as The Vanguard Group, Schwab Strategic Trust and iShares Trust funds appeared among its reported holders in filings and market data dated on or around 14 September 2026, together holding roughly 20% of shares outstanding across several passive fund vehicles; these figures reflect index and ETF fund positions rather than a controlling stake. Trian Fund Management, L.P. was separately disclosed as the largest concentrated shareholder, reporting a stake of approximately 20.6% and holding board representation since 2022 as a shareholder since 2020.
On 30 June 2026, Janus Henderson completed a take-private acquisition. Public shareholders (other than Trian, which rolled over part of its stake) received $52.00 per share in cash, the company’s shares were delisted from the NYSE, and it is now privately held by an investor group comprising Trian Fund Management, General Catalyst, the Qatar Investment Authority, Sun Hung Kai & Co. Limited, Lunate Capital Limited, MassMutual and other co-investors named in the transaction announcement. The relative post-completion ownership percentages of these parties have not been made public.
Ultimate beneficial ownership
No single individual has been officially disclosed as an ultimate beneficial owner of Janus Henderson Group Ltd. The post-completion investor group is composed of institutional and corporate entities (an investment firm, a venture firm, a sovereign wealth fund and others); available sources do not provide a complete ownership chain to an identifiable natural person, so no UBO percentage can be reliably calculated.
Data availability
Shareholder disclosure is major shareholders only and now historical for the pre-30 June 2026 public-company period; post-completion ownership of the now-private company is restricted, as no SEC or Jersey filing publicly discloses the individual stakes of the acquiring investor group.
