23 Note: Outperformance is measured based on composite performance gross of fees vs 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 vs zero for absolute retu rn strategies, (2) fund net of fees vs primary index or (3) fund net of fees vs 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 account s with no corresponding composite are excluded from the analysis. Excluded assets represent 5% of AUM across all time periods. Capabilities defined by Janus Henderson.

The top two Morningstar quartiles represent funds in the top half of their category based on total return. For the 1 - , 3 - , 5 - a nd 10 - year periods ending 31 March 2022, 51%, 53%, 54% and 66% of the 190, 182, 178 and 149 total mutual funds, respectively, were in the top 2 Morningsta r quartiles. Analysis based on ‘primary’ share class (Class I Shares, Institutional Shares or share class with longest history for US 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 b y s hare class. Rankings may be based, in part, on the performance of a predecessor fund or share class and are calculated by Morningstar using a methodol ogy that differs from that used by Janus Henderson. Methodology differences may have a material effect on the return and therefore the ranking. When an exp ense waiver is in effect, it may have a material effect on the total return, and therefore the ranking for the period. ETFs and funds not ranked by Morningstar are excluded from the analysis. Capabilities defined by Janus Henderson. © 2022 Morn in gstar, Inc.

31 ALTERNATIVE PERFORMANCE MEASURES Footnotes to reconciliation of adjusted financial measures 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 service 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 . 2 Adjustments for the three months ended 31 March 2022 consist primarily of long - term incentive plan expense associated with accelerated vesting of awards related to the retirement of our CEO and CIO, deal costs associated with the sale of Intech and rent expense for subleased office space . Adjustments for the three months ended 31 March 2021 and 31 December 2021 consist primarily of rent expense for subleased office space . JHG management believes these costs are not representative of the ongoing operations of the Group . 3 Investment management contracts have been identified as a separately identifiable intangible asset arising on the acquisition of subsidiaries and businesses . Such contracts are recognised 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 amortised on a straight - line basis over the expected life of the contracts . In addition, the adjustment for the three months ended 31 March 2022 includes an out - of - period incremental goodwill impairment charge, and the adjustments for the three months ended 31 March 2021 and 31 December 2021 include impairment charges of certain mutual fund investment management agreements and trademarks . JHG management believes these non - cash and acquisition - related costs are not representative of the ongoing operations of the Group . 4 Adjustments primarily represent contingent consideration adjustments associated with prior acquisitions . In addition, the adjustment for the three months ended 31 March 2022 includes a one - time charge related to the sale of Intech . JHG management believes these costs are not representative of the ongoing operations of the Group . 5 The tax impact of the adjustments is calculated based on the applicable US or foreign statutory tax rate as it relates to each adjustment . Certain adjustments are either not taxable or not tax - deductible .
