Solid investment performance, with 65%, 65%, 65%, and 67% of assets under management ("AUM") outperforming relevant benchmarks on a one-, three-, five-, and 10-year basis, respectively, as of December 31, 2025

AUM of US$493 billion as of December 31, 2025, an increase of 30% year over year

Fourth quarter 2025 breakeven net flows and US$56.5 billion of net inflows in 2025 compared to US$2.4 billion of net inflows in 2024

Fourth quarter 2025 diluted EPS of US$2.62 and adjusted diluted EPS of US$2.01 were impacted by extraordinary annual performance fee revenue

Janus Henderson Group plc (NYSE:JHG, "JHG, ", ", Janus Henderson, " or the "Company")) published its fourth quarter and full-year 2025 results for the period ended December 31, 2025. Fourth quarter 2025 operating income was US$487.4 million compared to US$172.0 million in the third quarter 2025 and US$197.5 million in the fourth quarter 2024. Adjusted operating income, adjusted for one-time, acquisition and transaction related costs, was US$383.7 million in the fourth quarter 2025 compared to US$204.5 million in the third quarter 2025 and US$204.7 million in the fourth quarter 2024.

Fourth quarter 2025 diluted earnings per share of US$2.62 compared to US$0.92 in the third quarter 2025 and US$0.77 in the fourth quarter 2024. Adjusted diluted earnings per share of US$2.01 in the fourth quarter 2025 compared to US$1.09 in the third quarter 2025 and compared to US$1.07 in the fourth quarter 2024.

Ali Dibadj, Chief Executive Officer, stated:

"Despite a deceleration in inflows, we ended 2025 with solid fourth quarter results that delivered improvements in adjusted operating revenue, operating income, and EPS, driven mostly by markets and strong annual performance fees. In 2025, we demonstrated several signs of continued progress across the business thanks to our valued employees, who have worked together to execute our strategy to Protect and Grow, Amplify, and Diversify our business. Along these lines, the previously announced definitive agreement to acquire Richard Bernstein Advisors (RBA) will position Janus Henderson as a leading model portfolio and separately managed account (SMA) provider. At the completion of the transaction, Janus Henderson will rank among the top 10 model portfolio providers in North America, placing it at the forefront of an industry that is well positioned for growth. In addition, RBA's deep expertise in model and SMA distribution will allow Janus Henderson to strengthen its distribution capabilities, including with wirehouses and Registered Investment Advisors. We look forward to welcoming the RBA team as new colleagues of Janus Henderson and look forward to growing the business for our clients, together. Going forward, we will continue to invest more in our brand, technology, and talented people, underscoring our unwavering commitment to deliver for our clients.

"In that context, the previously announced definitive merger agreement to be acquired by Trian and General Catalyst marks an important step forward for the Company. We believe this proposed transaction delivers compelling, immediate value to our shareholders while allowing us to invest further in our product offering, client services, technology, and talent. Our focus remains where it belongs—on delivering differentiated insights, disciplined investment excellence, and world-class service to our clients."

PROPOSED MERGER

As previously announced on December 22, 2025, the Company has entered into a definitive merger agreement to be acquired by an investor group led by funds and investment vehicles associated with Trian Fund Management, L.P. and General Catalyst Group Management, LLC (the "Proposed Transaction").

SHARE REPURCHASE AND DIVIDEND

As a result of the Proposed Transaction, the Company is suspending the payment of the regular quarterly dividend.

Prior to the Proposed Transaction announcement, as part of the Company's Board-approved US$200 million on-market share repurchase program, JHG purchased approximately 0.6 million shares of its common stock on the New York Stock Exchange (NYSE) in the fourth quarter 2025, for a total outlay of approximately US$27 million.

AUM AND FLOWS (in US$ billions)

FX reflects movement in AUM resulting from changes in foreign currency rates as non-US$ denominated AUM is translated into US$. Redemptions include impact of client transfers.

Outperformance is measured based on composite performance gross of fees versus primary benchmark, except where a strategy has no benchmark index or corresponding composite in which case the most relevant metric is used: (1) composite gross of fees versus zero for absolute return strategies, (2) fund net of fees versus primary index, or (3) fund net of fees versus Morningstar peer group average or median. Non-discretionary and separately managed account assets are included with a corresponding composite where applicable.

Cash management vehicles; ETF-enhanced beta strategies; legacy Tabula passive ETFs; Fixed Income Buy & Maintain mandates; legacy Guardian, NBK Capital Partners, and Victory Park Capital funds; Managed CDOs; Private Equity funds; and custom non-discretionary accounts with no corresponding composite are excluded from the analysis.

The top two Morningstar quartiles represent funds in the top half of their category based on total return. For the 1-, 3-, 5-, and 10-year periods ending December 31, 2025, 64%, 53%, 52%, and 54% of the 187, 173, 162, and 140 total mutual funds, respectively, were in the top 2 Morningstar quartiles.

Analysis based on "primary" share class (Class I Shares, Institutional Shares, or share class with longest history for U.S. Trusts; Class H Shares or share class with longest history for Dublin based; primary share class as defined by Morningstar for other funds). Performance may vary by share class. Rankings may be based, in part, on the performance of a predecessor fund or share class and are calculated by Morningstar using a methodology that differs from that used by Janus Henderson. Methodology differences may have a material effect on the return and therefore the ranking. When an expense waiver is in effect, it may have a material effect on the total return, and therefore the ranking for the period.

As previously announced, while the Proposed Transaction is pending, the Company will not hold conference calls or live webcasts to discuss its financial results. However, access to the slides accompanying this release will be available via the investor relations section of Janus Henderson's website (ir.janushenderson.com).

Reconciliation of non-GAAP financial information

In addition to financial results reported in accordance with GAAP, we compute certain financial measures using non-GAAP components, as defined by the SEC. These measures are not in accordance with, or a substitute for, GAAP, and our financial measures may be different from non-GAAP financial measures used by other companies. We have provided a reconciliation of our non-GAAP components to the most directly comparable GAAP components. The following are reconciliations of GAAP revenue, operating expenses, operating income, net income attributable to JHG, and diluted earnings per share to adjusted revenue, adjusted operating expenses, adjusted operating income, adjusted net income attributable to JHG, and adjusted diluted earnings per share.

__________

¹		JHG contracts with third-party intermediaries to distribute and service certain of its investment products. Fees for distribution and servicing related activities are either provided for separately in an investment product's prospectus or are part of the management fee. Under both arrangements, the fees are collected by JHG and passed through to third-party intermediaries who are responsible for performing the applicable services. The majority of distribution and servicing fees collected by JHG are passed through to third-party intermediaries. JHG management believes that the deduction of distribution and servicing fees from revenue in the computation of adjusted revenue reflects the pass-through nature of these revenues. In certain arrangements, JHG performs the distribution and servicing activities and retains the applicable fees. Revenues for distribution and servicing activities performed by JHG are not deducted from GAAP revenue. In addition to the adjustments related to distribution and servicing activities, other revenue for the three months ended December 31, 2024, and the years ended December 31, 2025 and 2024, includes an adjustment related to an employee secondment arrangement with a joint venture. The arrangement is pass-through in nature, and we believe the costs do not represent our ongoing operations.

²		Reconciling items for the three months ended December 31, 2025, primarily include:
		• In the three months ended December 31, 2025, we recognized significant performance fees from certain of our funds. A material portion of the direct compensation cost generated by this revenue is deferred into future periods on a U.S. GAAP basis. Given the magnitude of this performance fee revenue, the adjusted results for the three months ended December 31, 2025, accelerate the deferred cost of US$125.8 million in the same period as the associated revenue to better align the economics created by these performance fees.
		• An adjustment to remove the accelerated amortization related to the strategic decision to transition our investment management platform to Aladdin.
		• An adjustment to remove certain legal and consulting costs related to certain acquisitions and the merger agreement.
		Reconciling items for the three months ended September 30, 2025, primarily include:
		• An adjustment to remove the accelerated amortization related to the strategic decision to transition our investment management platform to Aladdin.
		• An adjustment to remove employee redundancy expenses and the acceleration of long-term incentive plan expense related to the departure of certain employees.
		Reconciling items for the three months ended December 31, 2024, primarily include:
		• An adjustment to remove employee redundancy expenses and the acceleration of long-term incentive plan expense related to the departure of certain employees.
		• An adjustment to remove certain acquisition-related expenses.
		• An adjustment to remove the expense impact associated with a pass-through employee secondment arrangement with a joint venture.
		Reconciling items for the year ended December 31, 2025, primarily include:

		• An adjustment to remove employee redundancy expenses and the acceleration of long-term incentive plan expenses related to the departure of certain employees.
		• An adjustment to remove certain acquisition-related expenses.
		• An adjustment to remove the expense impact associated with a pass-through employee secondment arrangement with a joint venture.
		JHG management believes these costs do not represent our ongoing operations.

³		Investment management contracts have been identified as a separately identifiable intangible asset arising on the acquisition of subsidiaries and businesses. Such contracts are recognized at the net present value of the expected future cash flows arising from the contracts at the date of acquisition. The intangible assets are amortized on a straight-line basis over the expected life of the assets, and the amortization of the assets is removed from our adjusted results. In addition, the reconciliation for the three months ended September 30, 2025, and the year ended December 31, 2025, includes an adjustment to remove the impairment expense associated with the impairment of certain capitalized costs related to the strategic decision to transition our investment management platform to Aladdin. JHG management believes these non-cash and acquisition-related costs are not representative of our ongoing operations.

⁴		Reconciling items for the three months ended December 31, 2025 and September 30, 2025, primarily include:
		• An adjustment to remove changes in fair value of acquisition-related contingent consideration, warrants and options.
		Reconciling items for the three months and year ended December 31, 2024, primarily include:
		• An adjustment to remove the reclassification of accumulated foreign currency translation reserves to net income. The reclassification resulted from the liquidation of JHG entities.
		Reconciling items for the year ended December 31, 2025, primarily include:
		• An adjustment to remove changes in fair value of acquisition-related contingent consideration, warrants and options.
		• An adjustment to remove the reclassification of accumulated foreign currency translation reserves to net income. The reclassification resulted from the liquidation of JHG entities.
		JHG management believes these costs do not represent our ongoing operations.

⁵		The tax impact of the adjustments is calculated based on the applicable U.S. or foreign statutory tax rate as it relates to each adjustment. Certain adjustments are either not taxable or not tax-deductible.

⁶		Reconciling items for all periods presented include an adjustment to remove the noncontrolling interest on amortization of acquisition-related intangible assets. JHG management believes these non-cash and acquisition-related costs are not representative of our ongoing operations.

Basis of preparation

In the opinion of management of Janus Henderson Group plc, the condensed consolidated financial statements contain all normal recurring adjustments necessary to fairly present the financial position, results of operations, and cash flows of JHG in accordance with GAAP. Such financial statements have been prepared in accordance with the instructions to Form 10‑Q pursuant to the rules and regulations of the SEC. Certain information and footnote disclosures normally included in financial statements prepared in accordance with GAAP have been condensed or omitted pursuant to such rules and regulations. The financial statements should be read in conjunction with the annual consolidated financial statements and notes presented in Janus Henderson's Annual Report on Form 10‑K for the year ended December 31, 2024, filed with the SEC (Commission File No. 001‑38103). Events subsequent to the balance sheet date have been evaluated for inclusion in the financial statements through the issuance date and are included in the notes to the condensed consolidated financial statements.

Past performance is no guarantee of future results. Investing involves risk, including the possible loss of principal and fluctuation of value.

Forward-looking statements

Certain statements in this press release not based on historical facts are "forward-looking statements" within the meaning of the federal securities laws. Such forward-looking statements involve known and unknown risks and uncertainties that are difficult to predict and could cause our actual results, performance or achievements to differ materially from those discussed. These include statements as to our future expectations, beliefs, plans, strategies, objectives, events, conditions, financial performance, prospects or future events, including with respect to the timing and anticipated benefits of pending and recently completed transactions and strategic partnerships, and expectations regarding opportunities that align with our strategy. In some cases, forward-looking statements can be identified by the use of words such as "may," "could," "expect," "intend," "plan," "seek," "anticipate," "believe," "estimate," "predict," "potential," "continue," "likely," "will," "would," and similar words and phrases. Forward-looking statements are necessarily based on estimates and assumptions that, while considered reasonable by us and our management, are inherently uncertain. Accordingly, you should not place undue reliance on forward-looking statements, which speak only as of the date they are made and are not guarantees of future performance. We do not undertake any obligation to publicly update or revise these forward-looking statements.

Various risks, uncertainties, assumptions and factors that could cause our future results to differ materially from those expressed by the forward-looking statements included in this press release include, but are not limited to, Janus Henderson's ability to obtain the regulatory, shareholder and other approvals required to consummate the Proposed Transaction and the timing of the closing of the Proposed Transaction, including the risks that a condition to closing would not be satisfied within the expected timeframe or at all or that the closing of the Proposed Transaction would not occur, the outcome of any legal proceedings that may be instituted against the parties and others related to the merger agreement, that shareholder litigation in connection with the Proposed Transaction may affect the timing or occurrence of the Proposed Transaction or result in significant costs of defense, indemnification and liability, unanticipated difficulties or expenditures relating to the Proposed Transaction, including the impact of the transaction on Janus Henderson's business, that the Proposed Transaction generally may involve unexpected costs, liabilities or delays, that the business of the Company may suffer as a result of uncertainty surrounding the Proposed Transaction or the identity of the purchaser, that the Company may be adversely affected by other economic, business, and/or competitive factors, including the net asset value of assets in certain of the Company's funds, and/or potential difficulties in employee retention as a result of the announcement and pendency of the Proposed Transaction, changes in interest rates and inflation, changes in trade policies (including the imposition of new or increased tariffs), volatility or disruption in financial markets, our investment performance as compared to third-party benchmarks or competitive products, redemptions, and other risks, uncertainties, assumptions, and factors discussed in our Annual Report on Form 10-K for the year ended December 31, 2024, and in other filings or furnishings made by Janus Henderson with the SEC from time to time.
