Ali Dibadj, Chief Executive Officer, stated:

"The year ended strongly with fourth quarter results that delivered year-over-year improvement in net flows, a stable management fee rate, solid core revenues, continued cost management, growth in operating income and EPS, and an AUM tailwind entering 2024.

"The tremendous amount of work that began in 2022 to reposition Janus Henderson for greater success is paying off, as evidenced in our 2023 results. During 2023, we executed on our strategy, implemented cost efficiencies to facilitate strategic reinvestment in the business, simplified our operating model, and reinforced our culture through articulating our Mission, Values, and Purpose—all while keeping our clients, and their clients, at the heart of everything we do.

"The current environment remains uncertain, geopolitical tensions are heightened, and we continue to face industry headwinds. Throughout, our focus remains the same—we will control what we can control and position Janus Henderson for growth. We have a fortress balance sheet, strong cash generation, disciplined investment teams and processes, and efficient cost management.

"As we enter 2024, and mark Janus Henderson's 90^th anniversary of providing a world-class investment experience, we are encouraged by many signs of clear progress, which we believe has us squarely on the path to achieving our ambitions of organic growth and delivering superior outcomes for our clients, their clients, colleagues, shareholders, and other stakeholders."

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, Managed CDOs, Private Equity funds, and custom non-discretionary accounts with no corresponding composite are excluded from the analysis. Performance across all time periods excludes Intech, the sale of which was completed March 31, 2022. Excluded assets represent 3% of AUM. Capabilities defined by Janus Henderson.

Performance across all time periods excludes Intech, the sale of which was completed March 31, 2022. 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, 2023, 51%, 50%, 53%, and 64% of the 182, 173, 164, and 151 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 A 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.

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.

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.

Adjustments include rent expense, rent income, other rent-related adjustments associated with subleased office space, and the acceleration of long-term incentive plan expense related to the departure of certain employees. Adjustments for the three months and year ended December 31, 2023, also include a US$9.3 million charge related to a separately managed account trade error. Adjustments for the three months and year ended December 31, 2022, also include redundancy payments associated with the reduction in force. JHG management believes these costs are not representative of our ongoing operations.

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. For segregated mandate contracts, the intangible asset is amortized on a straight-line basis over the expected life of the contracts. Adjustments for the three months and year ended December 31, 2022, also include impairment charges of certain mutual fund investment management contracts, client relationships and trademarks. JHG management believes these non-cash and acquisition-related costs are not representative of our ongoing operations.

⁴

Adjustments for the year ended December 31, 2023, include a provision for a credit loss and a contingent consideration fair value adjustment related to the 2022 sale of Intech, a correction due to an error of previously recognized earnings associated with an equity method investment and accumulated foreign currency translation expense related to JHG liquidated entities. Adjustments for the three months ended December 31, 2023, primarily consist of accumulated foreign currency translation expense related to JHG liquidated entities. The adjustment for the three months ended September 30, 2023, consists of a provision for a credit loss and a contingent consideration fair value adjustment related to the 2022 sale of Intech. JHG management believes these costs are not representative of 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. In addition, adjustments for the year ended December 31, 2023, were impacted by the change to our state tax rate. As a result, the U.S. deferred tax assets and liabilities were revalued from 23.9% to 23.5%, creating a non-cash deferred tax benefit of US$8.8 million.

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, 2022, 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.
